We present CO observations of 78 spiral galaxies in local merger pairs. These galaxies represent a subsample of a Ks-band-selected sample consisting of 88 close major-merger pairs (HKPAIRs), 44 spiral–spiral (S+S) pairs, and 44 spiral–elliptical (S+E) pairs, with separation <20 h−1 kpc and mass ratio <2.5. For all objects, the star formation rate (SFR) and dust mass were derived from Herschel PACS and SPIRE data, and the atomic gas mass, MHI, from the Green Bank Telescope HI observations. The complete data set allows us to study the relation between gas (atomic and molecular) mass, dust mass, and SFR in merger galaxies. We derive the molecular gas fraction (MH2/M*), molecular-to-atomic gas mass ratio (MH2/MHI), gas-to-dust mass ratio and SFE (= SFR/MH2) and study their dependences on pair type (S+S compared to S+E), stellar mass, and the presence of morphological interaction signs. We find an overall moderate enhancement (∼2×) in both molecular gas fraction (MH2/M*) and molecular-to-atomic gas ratio (MH2/MHI) for star-forming galaxies in major-merger pairs compared to non-interacting comparison samples, whereas no enhancement was found for the SFE nor for the total gas mass fraction ((MHI + MH2)/M*). When divided into S+S and S+E, low mass and high mass, and with and without interaction signs, there is a small difference in SFE, a moderate difference in MH2/M*, and a strong difference in MH2/MHI between subsamples. For the molecular-to-atomic gas ratio MH2/MHI, the difference between S+S and S+E subsamples is 0.55 ± 0.18 dex and between pairs with and without interaction sign 0.65 ± 0.16 dex. Together, our results suggest that (1) star formation enhancement in close major-merger pairs occurs mainly in S+S pairs after the first close encounter (indicated by interaction signs) because the HI gas is compressed into star-forming molecular gas by the tidal torque; and (2) this effect is much weakened in the S+E pairs.

This study examined median household income (MHI) of communities with community emergency response teams (CERTs). Preliminary data from New York City showed that in three of five counties, the mean MHI in CERT communities exceeded countywide MHI by up to $19,000. The research was then expanded to New Jersey, where, of 18 counties with CERTs, the mean MHI exceeded the countywide MHI in 15 counties (83 percent of the time). In counties where the mean CERT-community MHI was higher, it exceeded the county MHI by $6,060. Mean CERT-community MHI also exceeded the state’s MHI by over $5,000 ($60,745 versus $55,146). Given recent examples of the vulnerability of poor and working-class communities, emergency management agencies at all levels need to target CERT resources based on need, not on demand.

Previous studies suggested either census-tract-level median household income (MHI) or median family income (MFI) estimates may be used as a unidimensional measure of neighborhood socioeconomic status (SES) in the United States (US). To better understand its general use, the purpose of this study was to assess the usefulness of MHI and MFI in a wide range of geographic areas. Area-based socioeconomic data at the census tract level were obtained from the 2000 Census as well as the 2005–2009, 2010–2014, and 2015–2019 American Community Survey. MHI and MFI were used as two simple measures of neighborhood SES. Based on the five area-based indexes developed in the US, several census-tract-level socioeconomic indicators were used to derive five composite measures of neighborhood SES. Then, a series of correlation analyses was conducted to assess the relationships between these seven measures in the State of California and its seven Metropolitan Statistical Areas. Two simple measures were very strongly and positively correlated with one another, and were also strongly or very strongly correlated, either positively or negatively, with five composite measures. Hence, the results of this study support an analytical thinking that simple measures and composite measures may capture the same dimension of neighborhood SES in different geographic areas.

e17113 Background: Previous reports suggest that men with MHI who subsequently develop PC have worse outcomes. However, it has not been established whether a history of MHI is associated with a PC diagnosis (dx) or more aggressive PC. The objective of this study was to (i) investigate the assoc between MHI and development of PC, and (ii) in a subset of men with available Gleason Score (GS) data, assess the assoc between MHI and aggressive PC as measured by GS ≥7 PC at dx. Methods: This was a retrospective matched-cohort analysis to assess the assoc between MHI and time to PC dx in the Veterans Affairs (VA) Health Care System. Men with an ICD code for MHI dx between 2000-2020 were matched 1:1 to men with no MHI dx in the same time frame. The MHI dx date of the exposed (exp) male was assigned as the index date of the unexp male. Variables matched on included race, age at MHI exp (+/- 3 years), census region, and median household income. Uni- and multivariable competing risks models were used to test the assoc between MHI and time to PC using death from other causes as competing risk. In a subset of men with GS data available, logistic regression was used to test the assoc between MHI and GS ≥7 at PC dx. All multivariable models were adjusted for age, race, census region, income, Charlson Comorbidity Index, year of MHI index, and year of VA entry. Results: There were 2,597,810 MHI-exp men matched 1:1 to unexp men. During a median (Q1, Q3) follow up of 128 (65, 192) months, 390,977 PC diagnoses were observed (172,442 MHI-exp vs. 218,535 unexp). MHI-exp men were significantly less likely to be diagnosed with PC than unexp men in both uni- (HR: 0.798, 95% CI: 0.793-0.803) and multivariable (HR: 0.763, 95% CI: 0.758-0.768) analysis. Cumulative incidence estimates at 3, 5, 10, and 20 years were 2.1%, 3.1%, 5.2%, and 8.5%, respectively, for MHI-exp men vs 2.9%, 4.2%, 6.9%, and 11.7%, respectively, for unexp men. Among men with PC and available GS data (n = 51,404), 32,645 had GS ≥7 PC, of which 20,749 were MHI-exp vs 11,896 unexp. MHI-exp men had significantly higher odds of GS ≥7 PC in both uni- (OR: 2.38, 95% CI: 2.32-2.43) and multivariable (OR: 1.97, 95% CI: 1.92-2.02) analysis. Conclusions: Men with MHI are 20% less likely to be diagnosed with PC, however when diagnosed, are nearly 2 times more likely to have aggressive PC compared to non-MHI men. Although speculative based on the nature of the study, this may be due to poorer access to preventative health services resulting in delayed diagnoses.

11556 Background: Anxiety and depression are associated with decreased quality of life, treatment adherence, and survival in patients with cancer. Mental Health Inventory (MHI-17) is a validated screening tool for psychological well-being, but cut points for older adults with cancer are unknown. The goal of this study is to identify cut points on MHI-17 Anxiety (MHI-A) and Depression (MHI-D) subscales which correlate with patient-reported anxiety and depression in older adults with cancer. Methods: This is a secondary analysis of baseline data from a randomized controlled trial in adults aged 65+ with solid tumors starting chemotherapy. At baseline, patients completed MHI-17. MHI-A and MHI-D were calculated (range 0-100; higher scores represent better mental health). Self-reported anxiety was obtained from single-item Linear Analog Scale Assessment (0-5 = low, 6-10 = high). Self-reported depression was obtained from Yale Depression Screen, “Do you often feel sad or depressed?” The association of MHI-A and MHI-D with the patient-reported outcomes was analyzed using logistic regression. Youden’s index was used to determine the optimal cut points for MHI-A and MHI-D for identifying patients with high anxiety and depression. Results: 458 patients (median age 71 (range 65-91), 57% female, 55% non-Hispanic white) were included in this analysis. The most common cancer types were: GI (31%), breast (19%), GU (18%), and pulmonary (16%); 75% had stage IV cancer. Twenty-four percent (N = 110) reported high anxiety and 21% (N = 97) depression. Median scores for MHI-A and MHI-D were 75 (range 0-100) and 80 (range 0-100). The optimal cut point for high anxiety on MHI-A was 65; this had an accuracy of 76.1%, a sensitivity of 71.8%, and a specificity of 77.5%. The optimal cut point for depression on MHI-D was 70; this had an accuracy of 80.1%, a sensitivity of 80.4%, and a specificity of 79.8%. Conclusions: The current study identified optimal cut points for MHI-Anxiety and MHI-Depression subscales to identify older adults with cancer starting chemotherapy with self-reported anxiety and depression. In the absence of patient-reported anxiety and depression, these cut points could be used to identify older patients with cancer at risk for poor mental health.

Mapping and monitoring the condition of mangrove forests is needed for environmental rehabilitation and conservation. Mangrove Health Index (MHI) using satellite image analysis is a new approach that can be used to determine the environmental quality of mangrove forest ecosystems. This study aims to determine the structure of the mangrove forest community and conduct a spatial and temporal MHI analysis in the coastal areas of Surabaya and Sidoarjo. The data used in this study were the results of field observations on 10 transects. MHI analysis using Sentinel 2 imagery recorded in 2015, 2018, 2021. The results of the analysis show that the most dominant mangrove species in the research location is Avicennia marina. Analysis of satellite imagery detects a significant increase in mangrove area from 2015 to 2021, which is more than 500 Ha. Based on the MHI analysis, there was a positive change from poor dominant mangrove forest conditions (MHI <33%) in 2015 to moderate (33.4% < MHI < 66.67%) to good (MHI > 66.68%). The increase in the area of mangrove forests is accompanied by improvements in ecosystem conditions with indicators of increasing MHI.

Background: In the Veterans Health Administration (VA), Primary Care-Mental Health Integration (PC-MHI) clinics offer mental health services embedded in primary care, a strategy shown to reduce overall specialty mental health clinic burden while facilitating prompt referrals when indicated. Among newly initiated patients, same-day access to PC-MHI from primary care increases subsequent specialty mental health engagement. However, the impact of virtual care on the association between same-day access to PC-MHI and subsequent mental health engagement remains unclear. Objective: To examine the effects of same-day access to PC-MHI and virtual care use on specialty mental health engagement. Methods: We used administrative data from 3066 veterans who initiated mental health care at a large, California VA PC-MHI clinic during 3/1/2018 to 2/28/2022 and had no previous mental health visits for at least 2 years prior to the index appointment. We conducted Poisson regression analyses to examine the effects of same-day access to PC-MHI, virtual access to PC-MHI and their combined effect on subsequent specialty mental health engagement. Results: Same-day access to PC-MHI from primary care was positively associated with specialty mental health engagement (IRR = 1.19; 95% CI 1.14-1.24). Virtual access to PC-MHI was negatively associated with specialty mental health engagement (IRR = 0.83; 95% CI 0.79-0.87). The positive effect of same-day access on specialty mental health engagement was smaller among patients who initiated PC-MHI in a virtual visit (IRR = 1.07) compared to in-person visits (IRR = 1.29; 95% CI 1.22-1.36). Conclusions: Although same-day access to PC-MHI increased overall specialty mental health engagement, the magnitude of this effect varied between in-person and virtual modalities. More research is needed to understand mechanisms of the association between virtual care use, same-day access to PC-MHI, and specialty mental health engagement.

As M-Health apps become more popular, users can access more mobile health information (MHI) through these platforms. Yet one preeminent question among both researchers and practitioners is how to bridge the gap between simply providing MHI and persuading users to buy into the MHI for health self-management. To solve this challenge, this study extends the Elaboration Likelihood Model to explore how to make MHI advice persuasive by identifying the important central and peripheral cues of MHI under individual difference. The proposed research model was validated through a survey. The results confirm that (1) both information matching and platform credibility, as central and peripheral cues, respectively, have significant positive effects on attitudes toward MHI, but only information matching could directly affect health behavior changes; (2) health concern significantly moderates the link between information matching and cognitive attitude and only marginally moderates the link between platform credibility and attitudes. Theoretical and practical implications are also discussed.

Detection of mental distress cases is essential in clinical practice, especially in primary care. Screening instruments could be useful and effective tools to help identify them. This study sought to evaluate the utility and capability of the Mental Health Inventory (MHI)-38 and MHI-5 in identifying cases suffering from mental distress from those who do not. The validity and accuracy of these MHI versions were tested using as gold standards: two samples of adults, one with clinical complaints ( n = 33) and another without clinical complaints ( n = 31); and the scores in Scales of Psychological Well-Being and in a psychopathology inventory (Minnesota Multiphasic Personality Inventory 2). Receiver operating characteristic curves were used to define cutpoints, which is the Youden’s index for the optimization criteria. The data analysis indicated an optimal cutpoint of 7.19 for MHI-38TOTAL and of 53 (recoded to a 0–100 scale) for MHI-5TOTAL to differentiate clinical cases from those who are not. These results indicate cutpoint values similar to those of previous studies in the case of MHI-5 and provide useful reference values for MHI-38. The need to replicate this study with larger samples and with controlled clinical conditions and type of pathology is also discussed.

AbstractPersistent cognitive complaints are common following a mild head injury (MHI), but deficits are rarely detected on neuropsychological tests. Our objective was to examine the effect of symptom expectation on self-report and cognitive performance measures in MHI individuals. Prior research suggests that when MHI participants are informed they may experience cognitive difficulties, they perform worse on neuropsychological tests compared to MHI participants who are uninformed. In this study, undergraduate students with and without a prior MHI were either informed that the study's purpose was to investigate the effects of MHI on cognitive functioning (“diagnosis threat” condition) or merely informed that their cognitive functioning was being examined, with no mention of status (“neutral” condition). “Diagnosis threat” MHIs self-reported more attention failures compared to “diagnosis threat” controls and “neutral” MHIs, and more memory failures compared to “diagnosis threat” controls. In the “neutral” condition, MHIs reported higher anxiety levels compared to controls and compared to “diagnosis threat” MHIs. Regardless of condition, MHIs performed worse on only one neuropsychological test of attention span. “Diagnosis threat” may contribute to the prevalence and persistence of cognitive complaints made by MHI individuals found in the literature, but may not have as strong of an effect on neuropsychological measures.

Abstract In Veterans Health Administration’s (VA) Primary Care–Mental Health Integration (PC-MHI) models, primary care providers, care managers, and mental health clinicians collaboratively provide depression care. Primary care patients, however, still lack timely, sufficient access to psychotherapy treatment. Adapting PC-MHI collaborative care to improve uptake of evidence-based computerized cognitive behavioral therapy (cCBT) may be a potential solution. Understanding primary care-based mental health clinician perspectives is crucial for facilitating adoption of cCBT as part of collaborative depression care. We examined PC-MHI mental health clinicians’ perspectives on adapting collaborative care models to support cCBT for VA primary care patients. We conducted 16 semi-structured interviews with PC-MHI nurse care managers, licensed social workers, psychologists, and psychiatrists in one VA health-care system. Interviews were audio-recorded, transcribed, coded using the constant comparative method, and analyzed for overarching themes. Although cCBT awareness and knowledge were not widespread, participants were highly accepting of enhancing PC-MHI models with cCBT for depression treatment. Participants supported cCBT delivery by a PC-MHI care manager or clinician and saw it as an additional tool to engage patients, particularly younger Veterans, in mental health treatment. They commented that current VA PC-MHI models did not facilitate, and had barriers to, use of online and mobile treatments. If effectively implemented, however, respondents thought it had potential to increase the number of patients they could treat. There is widespread interest in modernizing health systems. VA PC-MHI mental health clinicians appear open to adapting collaborative care to increase uptake of cCBT to improve psychotherapy access.

Abstract Background Glioblastoma is the most common and aggressive primary brain tumour in adults. The development of anti-cancer agents for brain tumours is challenged by the blood-brain barrier and the resistance conferred by the local tumour microenvironment. Heptamethine cyanine dyes (HMCDs) are a class of near-infrared fluorescence compounds that have recently emerged as promising agents for drug delivery Material and Methods We conjugated palbociclib, a cyclin-dependent kinase 4/6 inhibitor to the HMCD, MHI 148 for the treatment of GBM. Patient-derived GBM cell lines were established from surgically resected biopsy GBM tissue. Results High-throughput drug screening revealed an almost 100-fold increase in cytotoxicity of the palbociclib-MHI 148 conjugate compared to palbociclib alone. Moreover, the palbociclib-MHI 148 conjugate was synergistic with radiation, but not with temozolomide. Further analysis revealed the palbociclib-MHI 148 conjugate was superior to other cyclin-dependent kinase inhibitors in vitro. The shift of palbociclib from cytostatic to cytotoxic when conjugated to MHI 148 prompted further investigation. We revealed that palbociclib-MHI 148-dependent inhibition of cell-cycle progression resulted in increased DNA damage. This preceded increased transcription of key extrinsic apoptosis genes and caused a time-dependent upregulation of TNFR1 endocytosis-dependent cell death signalling. Notably, inhibition of endocytosis and siRNA knockdown of TNFR1 prevented palbociclib-MHI 148-induced cell death. Conclusion: These results highlight a novel mechanism of action of palbociclib when conjugated to MHI-148 that induced autocrine-driven TNFR1-mediated apoptosis. In addition, we highlight the potential application of HMCDs in repurposing tyrosine kinase inhibitors, to overcome the current limitations preventing the expansion of second-line treatment options for GBM.

AbstractMeloidogyne hispanica (Mhi) is a difficult-to-control polyphagous root-knot nematode (RKN) species of emerging importance for economically valuable crops. Nematode secretions are likely to be the first signals perceived by the plant and are thought to be involved in various aspects of the plant–nematode interaction. The aims of this work were to identify and characterize M. hispanica parasitism genes: cathepsin L cysteine protease (cpl-1), calreticulin (crt-1), β-1,4-endoglucanase-1 (eng-1) and manganese superoxide dismutase (mnsod). As there are no genomic data available for M. hispanica, primers were designed from the conserved regions of the putative parasitism genes in M.incognita and M. hapla and used to amplify the genes in M. hispanica, which led to the successful amplification of these genes in M. hispanica. Partial gene sequences were also obtained for M. arenaria, M. hapla, M. hispanica, M. incognita and M. javanicacpl-1, crt-1, eng-1 and mnsod genes, and their phylogenetic relationship analysed. In order to determine whether these genes are differentially expressed during M. hispanica development, cDNA was amplified from mRNA isolated from eggs, second-stage juveniles (J2) and females. Amplification products were observed from cDNA of all developmental stages for the Mhi-cpl-1 and Mhi-crt-1 genes. However, the gene Mhi-crt-1 exhibited intense amplification bands in females, while the Mhi-eng-1 gene was equally amplified in eggs and J2 and the Mhi-mnsod gene was only expressed in eggs. In comparison to the other RKN species, the genes Mhi-eng-1 and Mhi-mnsod showed transcription in different nematode developmental stages.

AbstractRecovery of cognitive function after mild head injury (MHI) is thought to be relatively swift and complete. The present study replicates and extends previous work in which university students with self-reported concussion demonstrated reduced P300 amplitude on a set of easy and difficult attention tasks, in addition to performing more poorly than controls on demanding cognitive tasks many years after injury. In the present study, 13 students with self-reported concussion (MHI group: M time since injury 5 8 years) and 10 controls were matched for age, sex, education, and a variety of cognitive, physical and emotional complaints. Controls outperformed the MHI group on the Digit Symbol substitution task and on a difficult dual task involving tone discrimination and visual working memory. Additionally, controls exhibited larger P300 amplitudes on both an easy and a difficult auditory discrimination task. A combination of electrophysiological, neuropsychological and self-report indices predicted group membership (MHI vs. control) with 88% accuracy. The present results, coupled with previous work, offer preliminary evidence that the combination of event-related potentials and demanding behavioral measures might reveal long-lasting, subtle cognitive problems associated with MHI. These findings may challenge existing notions of complete recovery after MHI.

Assessments of the cold-gas reservoir in galaxies are a cornerstone for understanding star-formation processes and the role of feedback and baryonic cycling in galaxy evolution. Here we exploit a sample of 392 galaxies (dubbed MAGMA, Metallicity and Gas for Mass Assembly), presented in a recent paper, to quantify molecular and atomic gas properties across a broad range in stellar mass, Mstar, from ∼107 − 1011 M⊙. First, we find the metallicity (Z) dependence of the conversion factor for CO luminosity to molecular H2 mass αCO to be shallower than previous estimates, with αCO ∝ (Z/Z⊙)−1.55. Second, molecular gas mass MH2 is found to be strongly correlated with Mstar and star-formation rate (SFR), enabling predictions of MH2 good to within ∼0.2 dex; analogous relations for atomic gas mass MHI and total gas mass Mgas are less accurate, ∼0.4 dex and ∼0.3 dex, respectively. Indeed, the behavior of atomic gas mass MHI in MAGMA scaling relations suggests that it may be a third, independent variable that encapsulates information about the circumgalactic environment and gas accretion. If Mgas is considered to depend on MHI, together with Mstar and SFR, we obtain a relation that predicts Mgas to within ∼0.05 dex. Finally, the analysis of depletion times and the scaling of MHI/Mstar and MH2/Mstar over three different mass bins suggests that the partition of gas and the regulation of star formation through gas content depends on the mass regime. Dwarf galaxies (Mstar ≲ 3 × 109 M⊙) tend to be overwhelmed by (H I) accretion, and despite short τH2 (and thus presumably high star-formation efficiency), star formation is unable to keep up with the gas supply. For galaxies in the intermediate Mstar “gas-equilibrium” bin (3 × 109 M⊙ ≲ Mstar ≲3 × 1010 M⊙), star formation proceeds apace with gas availability, and H I and H2 are both proportional to SFR. In the most massive “gas-poor, bimodality” regime (Mstar ≳ 3 × 1010 M⊙), H I does not apparently participate in star formation, although it generally dominates in mass over H2. Our results confirm that atomic gas plays a key role in baryonic cycling, and is a fundamental ingredient for current and future star formation, especially in dwarf galaxies.

This study demonstrates the feasibility of a view-based method, the motion history image (MHI) to map biospeckle activity around the scar region in a green orange fruit. The comparison of MHI with the routine intensity-based methods validated the effectiveness of the proposed method. The results show that MHI can be implementated as an alternative online image processing tool in the biospeckle analysis.

Modal interpretations are non-collapse interpretations, where the quantum state of a system describes its possible properties rather than the properties that it actually possesses. Among them, the atomic modal interpretation (AMI) assumes the existence of a special set of disjoint systems that fixes the preferred factorization of the Hilbert space. The aim of this paper is to analyze the relationship between the AMI and our recently presented modal-hamiltonian interpretation (MHI), by showing that the MHI can be viewed as a kind of “atomic” interpretation in two different senses. On the one hand, the MHI provides a precise criterion for the preferred factorization of the Hilbert space into factors representing elemental systems. On the other hand, the MHI identifies the atomic systems that represent elemental particles on the basis of the Galilei group. Finally, we will show that the MHI also introduces a decomposition of the Hilbert space of any elemental system, which determines with precision what observables acquire definite actual values.

BACKGROUND: There is an increase in students enrolled in higher education diagnosed with mental illness or experiencing symptoms suggestive of mental health issues (MHI). This has a significant impact on the faculty–student relationship. OBJECTIVES: The purpose of this study was to identify the basic social psychological process that occurs when nursing faculty interact with students with MHI. DESIGN: Grounded theory methodology was implemented to identify the basic social psychological process that occurs when faculty encounter students with MHI. Thirteen nursing faculty were interviewed. Data were analyzed using line by line coding and constant comparative analysis. RESULTS: The resulting substantive theory, navigating the faculty–student relationship in the context of student MHI, is an iterative four-phase process: noticing, responding, experiencing, and reflecting. CONCLUSION: This theory provides a framework for understanding how nursing faculty recognize and address student MHI. The theory can be used to establish interventional strategies and best practice guidelines.

Texto completoResumen
Mild head injury (MHI) represents one of the most challenging neurological pathologies occurring during athletic participation. Athletic trainers and sports medicine personnel are often faced with decisions about the severity of head injury and the timing of an athlete's return to play following MHI. Returning an athlete to competition following MHI too early can be a catastrophic mistake. This case study involves a 20-year-old collegiate football player who sustained three mild head injuries during one season. The case study demonstrates how objective measures of balance and cognition can be used when making decisions about returning an athlete to play following MHI. These measures can be used to supplement the subjective guidelines proposed by many physicians.

AbstractWe investigated the function of the m. hyohyoideus superior (MHS) and inferior (MHI) in the head of three carp (Cyprinus carpio L., 29.7 ± 2.1 cm FL ) during three movements (normal breathing, stressed movements and food uptake). Both muscle parts are located ventrally at the inner side of the operculum and branchiostegal rays and consist of red (mainly in MHI) and white (mainly in MHS) fibres. Contrasting views exist about the functional role of these muscles during ventilation and food uptake. Therefore, we analysed muscle activities of the MHS and MHI using electromyography (EMG) and measured the strain pattern of the MHS using sonomicrometry. Carp were also filmed from a ventral viewpoint using high-speed video at 250 frames s-1. EMG and sonomicrometry data showed an increase in muscle strain amplitudes, cycle frequency and (relative) stimulus duration while stimulus on- and off-times occurred earlier in the strain cycle from normal breathing to stressed movements to food uptake. The MHS and MHI were always simultaneously active. We concluded that: 1) the MHI is not responsible for high frequency movements (i.e. stressed movements and food uptake); 2) both muscle parts assist in the onset of opercular closing, and 3) the MHS and MHI do not act as antagonists in carp.

New estimates of median body length at sexual maturity (L50) are presented for females of ehu (Etelis carbunculus) and kalekale (Pristipomoides sieboldii) in the main Hawaiian Islands (MHI); these are compared with published estimates for females of each species in the north-western Hawaiian Islands (NWHI). This case study illustrates the general importance of identifying regional and subregional variations in species’ life histories when estimating parameters for input to stock assessments. L50 values differed somewhat between the two species, but greatly between the MHI and NWHI for each species. Size-standardised ovary weights were greater in the NWHI v. MHI for all-sized fish of both species and nominally greater at larger body sizes among the mature females of both species in the MHI compared with the NWHI. L50 was smaller in the MHI compared with NWHI for females of both species. The mean (±s.e.m.) L50 for female ehu was 23.4±0.3- v. 27.2±1.0-cm fork length (FL) in the MHI v. NWHI respectively. For female kalekale, the respective estimates were 23.8±0.3 and 28.6±0.7cm FL. Possible determinants of these subregional geographic variations in L50, including latitude, productivity and history of extraction by Hawaiian bottomfish fisheries, are discussed.

This study examined the relationship between self ratings of recorded daydreams and mental health as measured by the Mental Health Index (MHI). Forty-eight subjects recorded at least five daydreams over a two-week period and completed the MHI. As predicted there was no relationship between the MHI and subjects' rating of how they felt during the daydream. After the daydream, distressed subjects rated the daydream as being more potent than healthy subjects. Consistent with the study's hypothesis, the difference score between the two daydream ratings was related to the MHI with measures of mental health positively related to change scores and measures of distress negatively related to change scores. Results were interpreted in terms of the role of daydreams in feedback loops and self-efficacy.

Most of the hollow carbon submicro-fibers (HCSFs) reported today are made from polyacrylonitrile (PAN) homopolymer. The obtained HCSFs are fragile due to the poor stabilization and spinnability of PAN. In this study, a bifunctional comonomer, β-methylhydrogen itaconate (MHI), was synthesized to prepare poly(acrylonitrile- co-β-methylhydrogen itaconate) [P(AN- co-MHI)] copolymer, which was used as a precursor to produce HCSF by coaxial electrospinning. The stabilization of P(AN- co-MHI) was studied by differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR); the structure of HCSFs was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and field emission scanning electron microscopy (FE-SEM). The stabilization of P(AN- co-MHI) has been improved significantly by MHI with lower cyclization temperature, broadened peak and lower activation energy, which is beneficial to producing high-performance HCSFs. HCSFs with fine and uniform structures were obtained after stabilization and carbonization; the diameter of the HCSFs shrinks due to the elimination of N and the extra H. The diameter and wall thickness of HCSFs can be controlled simply by the feeding ratio of P(AN- co-MHI) solution/styrene- co-acrylonitrile solution. The resultant HCSFs can be bent more than 280° without breaking, which has potential applications in lithium-ion rechargeable batteries, supercapacitors, fuel cells, and catalyst.

Introduction: Same-day referrals from primary care to mental health increase subsequent mental health treatment engagement. VA Primary Care-Mental Health Integration (PC-MHI) clinics offer integrated mental health services embedded in primary care clinics, providing a key entry point to mental health care. Although telehealth use expanded rapidly after the onset of COVID-19, the impact of telehealth on same-day primary care access among new PC-MHI mental health patients is unknown. To address this knowledge gap, we examined associations between telehealth use and same-day primary care access in VA PC-MHI. Methods: We examined electronic health record data to identify same-day primary care appointments among PC-MHI patients who initiated care during 3/1/2018 to 10/29/2021. We used logistic regression analyses to evaluate the effect of telehealth on same-day primary care access. Time, demographic characteristics, mental health diagnoses (PTSD and depression), and substance use disorder diagnosis were evaluated as covariates. Results: New PC-MHI patients who were seen via telehealth were less likely to receive same-day primary care access than patients seen in person (OR: 0.54; 95% CI: 0.41-0.71; P < .001). Conclusions: Despite the potential advantages of using telehealth to increase access, VA patients with an initial PC-MHI visit via telehealth were less likely than patients seen in person to be referred from primary care. Telehealth may adversely affect primary care referrals to mental health services, an outcome that could ultimately reduce specialty mental health care continuity. There is an urgent need to identify strategies to facilitate PC-MHI care coordination in the telehealth context.

Introduction. The critical problem of Russian health care is the deficit of funding for the program of state-guaranteed medical care for citizens of Russia. Purpose of the study. To search for solutions to the problem of financing the deficit of the program of state guarantees of free medical care in the Russian Federation. Material and methods. Retrospective data analysis was carried out to analyse the reasons for the deficit in the financing of the program of state guarantees of free medical care and search for solutions in the experience of other countries. Results. The analysis showed that the reasons for the deficit of the program of state guarantees of free medical care are the shortcomings of the mandatory health insurance (MHI) income system: linking contributions for the working population to the wages fund; the vagueness of the definition of the non-working population and the payment of contributions for its MHI by the constituent entities of the Russian Federation; non-participation of the solvent population in the co-financing of medical care; deficit of economic integration between the payment of MHI treatment and the health care system; the absence of formalized mechanisms for reimbursing the expenses of the MHI system by the federal budget to pay for aid in catastrophic situations. Discussion. The authors see the solution to the problem of the deficit of the program of state guarantees of free medical care in the modernization of the MHI income system: replacement of the MHI contributions paid by employers with an additional “medical” part of the value-added tax; replacement of the MHI contributions paid by the constituent entities of the Russian Federation for the non-working population with a targeted “medical” tax on retail sales; creation of a system of additional income based on the principle “the guilty person pays for causing harm to health”; recognition of the cost of medical care to the population in catastrophic situations as an unconditional obligation of the federal budget. Conclusion. a systemic solution to the problem of the financing deficit of the program of state guarantees of free medical care for the citizens of Russia seems to be the modernization of the MHI income system.

Introduction: After abdominal surgery, the patients who are separated from mechanical ventilation and provided with oxygen therapy via a T-piece are at risk for respiratory complications. Therefore, they need additional respiratory support. This study aimed to evaluate the effects of manual hyperinflation (MHI) on pulmonary function after weaning. Methods: This randomized clinical trial included 40 patients who had undergone abdominal surgery and were receiving oxygen via a T-piece. Patients were selected from the intensive care units (ICU) of two hospitals in Mashhad, Iran. The subjects were randomly allocated to intervention (MHI) and control groups. Patients in the MHI group were provided with three 20-minute MHI rounds using the Mapleson C, while the control group received routine cares. Tidal volume (Vt), Rapid Shallow Breathing Index (RSBI), and the ratio of arterial oxygen partial pressure to fractional inspired oxygen (P/F ratio) were measured before the intervention, as well as 5 and 20 minutes after the intervention. Atelectasis prevalence was assessed before and 24 hours after the intervention. Data were analysed by SPSS software version 13. Results: At baseline, there were no significant differences between the groups regarding Vt, RSBI, P/F ratio, and atelectasis rate. No significant difference was also found between the groups regarding atelectasis rate 24 hours after the intervention. However, at both posttests, Vt, RSBI, and P/F ratio in the MHI group were significantly better than the control group. Conclusion: In patients with artificial airway and spontaneous breathing, MHI improves pulmonary function.

Abstract Introduction: Although manual hyperinflation (MHI) is a physical therapy technique commonly used in intensive care and emergency units, there is little consensus about its use. Objective: To investigate the knowledge of physical therapists working in intensive care and emergency units about manual hyperinflation. Methods: Data were collected through self-administered questionnaires on manual hyperinflation. Data collection took place between September 2014 and January 2015, in Itabuna and Ilhéus, Bahia, Brazil. Results: The study sample was composed of 32 physical therapists who had between 4 months and 10 years working experience. All respondents affirmed that they used the technique in their professional practice. However, only 34.4% reported it to be a routine practice. 90.6% stated that the most common patient position during manual hyperinflation is “supine”. Participants were almost unanimous (93.8%) in citing secretion removal and cough stimulation as perceived benefits of MHI. High peak airway pressure was identified as being a precaution to treatment with MHI by 84.4% of participants, whilst 100% of the sample agreed that an undrained pneumothorax was a contraindication to MHI. Conclusion: The most common answers to the questionnaire were: supine position during MHI; secretion removal and cough stimulation as perceived benefits; high peak airway pressure as a precaution; and an undrained pneumothorax as a contraindication.

Introduction: Despite concerted efforts, Ukraine is challenged by increasing rates of multidrug and rifampicin-resistant tuberculosis (MDR/RR-TB) comorbid with alcohol use disorder (AUD). This study describes a cohort of RR-TB patients with high alcohol consumption treated in MSF Zhytomyr Project, Ukraine.
Methodology: We used programmatic data for 73 RR-TB patients screened with the AUD Identification Test March-July 2019 and followed-up for culture conversion/TB treatment outcome till 31 January 2020. We described socio-demographic, behavioral, and clinical characteristics, the level of depressive symptoms, and TB treatment outcomes in three groups: 1) patients with AUD who received mental health interventions (MHI); 2) patients with AUD who did not receive MHI; 3) patients with no AUD. We also found three potential contributors to declining to receive MHI.
Results: Main characteristics of the study groups did not differ substantially. Those receiving MHI (mean: nine sessions) were rated for alcohol consumption as ‘hazardous’ (41%), ‘harmful’ (43%) and ‘dependence’ (36%) and had higher depression scores versus the second (p=0.009) and third (p=0.095) groups at baseline. Depressive symptoms declined at 9-month follow-up for all patients. Culture conversion was seen at 77%, 73%, and 83% for each group respectively. We also found three reasons for declining from MHI.
Conclusions: We detected little differences across the groups. However, our study cohort demonstrated substantially higher adherence rates, culture conversion and reduction of depressive symptoms than reported globally. We recommend further research on the effectiveness of MHI in changing the drinking habits, quality of life and/or TB treatment outcomes of patients with AUD.

Although it is well known that patients with mild head injury (MHI) are less able to endure intense light and sound stimuli than normal people, there are few psychophysical studies that have objectively measured this type of hyperaesthesia. In the present study, using a computerised rating scale technique, both the maximal and submaximal levels of reduced tolerance to light and sound were assessed for a wide range of stimuli. Three to six days after the trauma, 40 MHI patients were significantly less tolerant to stimuli of intensities over 71 dB and 500 lux levels than controls. These intensities are common, and MHI patients may suffer as a consequence.

Background:Lack of sustainable and affordable health financing mechanisms in India has exposed the poor ininformal sector to iatrogenic poverty. Hardship financing of health services has negative financial consequences on thefuture income of these households. This can be mitigated through micro health insurance (MHI) because it aims to removefinancial barriers to access and utilize health services.Objectives:Recognizing the dearth of studies on impact of MHI schemes in India, we carried out an in-depth study onSampoorna Suraksha Programme (SSP) in Karnataka to assess the effect on access and utilization of healthcare services.Methods:We designed a descriptive cross sectional household survey that collected data from 1146 households toevaluate the impact using logistic regression analysis.Results:Insured individuals were more likely to access and utilize inpatient services compared to uninsured individuals.Moral hazard measured as length of stay in the hospital was absent. Horizontal equity in utilization based on gender andincome was observed. Insured used private providers than public hospitals or self-medicine. The results of the studysupport the positive impact of MHI on access and utilization of health services.Conclusion:The findings of the study enhance our understanding of the positive role of MHI in the promotion of betterhealth behavior of the poor people who usually forego treatment during illness. This would reinforce policymakers toadvocate MHI to mitigate iatrogenic poverty in India, the land of villages.

Combining near-infrared fluorescence (NIRF) and nuclear imaging techniques provides a novel approach for hepatocellular carcinoma (HCC) diagnosis. Here, we report the synthesis and characteristics of a dual-modality NIRF optical/positron emission tomography (PET) imaging probe using heptamethine carbocyanine dye and verify its feasibility in both nude mice and rabbits with orthotopic xenograft liver cancer. This dye, MHI-148, is an effective cancer-specific NIRF imaging agent and shows preferential uptake and retention in liver cancer. The corresponding NIRF imaging intensity reaches 109/cm2tumor area at 24 h after injection in mice with HCC subcutaneous tumors. The dye can be further conjugated with radionuclide68Ga (68Ga-MHI-148) for PET tracing. We applied the dual-modality methodology toward the detection of HCC in both patient-derived orthotopic xenograft (PDX) models and rabbit orthotopic transplantation models. NIRF/PET images showed clear tumor delineation after probe injection (MHI-148 and68Ga-MHI-148). The tumor-to-muscle (T/M) standardized uptake value (SUV) ratios were obtained from PET at 1 h after injection of68Ga-MHI-148, which was helpful for effectively capturing small tumors in mice (0.5 cm × 0.3 cm) and rabbits (1.2 cm × 1.8 cm). This cancer-targeting NIRF/PET dual-modality imaging probe provides a proof of principle for noninvasive detection of deep-tissue tumors in mouse and rabbit and is a promising technique for more accurate and early detection of HCC.

BackgroundA comparison of the performance of the 5-item mental health dimension of SF–36 (MHI–5) with that of the 12-item General Health Questionnaire (GHQ–12) in a defined, non-patient population, using standard statistical tests.MethodsA postal survey of 3000 patients aged 16–64 years was conducted. Patients were randomly selected from the practice lists of two general practices chosen to represent populations with different socio-economic characteristics.ResultsConsiderable evidence was found for the internal consistency of both instruments (Cronbach's α 0.91 and 0.84 for GHQ–12 and the MHI–5 respectively) and for their construct validity in terms of distinguishing between groups with measured health differences. Both instruments showed a significant difference in the mean scores for men and women. In contrast to the GHQ–12, no correlation was found between age and score for the MHI–5. Both instruments were equally sensitive to socio-economic characteristics and to levels of social support The scores on the two instruments were highly correlated (Spearman rank correlation – 0.73).ConclusionThe MHI–5 has comparable psychometric performance to the GHQ–12, and can be used to measure and compare mental health in defined populations. Operational advantages of the MHI–5 over the GHQ–12 are that it is in the public domain, is part of a general health measure (SF–36) and is shorter.

Integration of ecological and genetic data to study patterns of biological connectivity can aid in ecosystem-based management. Here we investigated connectivity of the Hawaiian grouperEpinephelus quernus, a species of management concern within the Main Hawaiian Islands (MHI), by comparing genetic analyses with simulated larval dispersal patterns across the species range in the Hawaiian Archipelago and Johnston Atoll. Larval simulations revealed higher dispersal from the MHI to the Northwestern Hawaiian Islands (NWHI) than in the opposite direction and evidence for a dispersal corridor between Johnston and the middle of the Hawaiian Archipelago. Genetic analyses using mitochondrial DNA (mtDNA) control region sequences and microsatellites revealed relatively high connectivity across the Hawaiian Archipelago, with the exception of genetically distinct populations and higher mtDNA diversity in the mid-Archipelago. These analyses support the preservation of the mid-archipelago as a source of genetic diversity and a region of connectivity with locations outside the Hawaiian Archipelago. Additionally, our evidence for directional dispersal away from the MHI lends caution to any management decisions that would rely on the NWHI replenishing depleted MHI stocks.

This study aimed to show the impact of different extents of internal limiting membrane (ILM) peeling on visual and anatomical outcomes following idiopathic full-thickness macular hole (FTMH) surgery. Methods. In this single-center prospective study, patients with idiopathic FTMH underwent standard pars plana vitrectomy with two different extents of ILM peeling: 2-disc diameters (DD) or 4 DD. The main outcome measures were the closure rate of the holes based on optical coherence tomography (OCT) findings at three months after surgery. Results. Forty eyes from 39 patients were enrolled in the study. After three months, anatomical closure was achieved in 78% and 76% eyes in 2 DD peel and 4 DD peel groups, respectively. From 29 eyes with macular hole index (MHI) ≤ 0.5, type 1 closure was achieved in 42% eyes receiving a 2 DD ILM peel, compared to 66% eyes receiving a 4 DD peel p=0.041. In comparison, this significant difference was not seen in the subgroup of MHI > 0.5 p=061. In the subgroup of subjects with baseline MHI ≤ 0.5, visual improvement was significantly more in eyes with 4 DD ILM peeling p=0.034, which was not seen in the MHI > 0.5 subgroup p=0.61. Conclusion. In patients with idiopathic full‐thickness macular hole (MHI ≤ 0.5), a larger ILM peel of 4 DD appears to yield better anatomical outcomes than a more limited 2 DD peel.

INTRODUCTION: Measurement-based care (MBC) uses standardized measurement to systematically monitor treatment response over time. Although MBC is underutilized in mental health settings, primary care–mental health integration (PC-MHI) settings are expected to provide MBC. This article describes a quality improvement (QI) process to increase Patient Health Questionnaire-9 (PHQ9) utilization within a PC-MHI setting. AIMS: Pre-intervention, rates of baseline and follow-up PHQ9 administration for veterans with a depressive disorder were 76% and 35%, respectively. This article describes a QI process to increase PHQ9 utilization rates within a PC-MHI setting, with the goal to improve provider PHQ9 utilization rates at baseline and within 4-week follow-up to 90%. METHOD: An educational intervention and weekly motivational enhancement sessions were implemented in 2017. Chart review data compared PHQ9 utilization rates from fall 2016 and 2017. RESULTS: Following intervention, provider PHQ9 utilization rates increased to 98% and 88% at baseline and follow-up. CONCLUSIONS: These findings demonstrate that a brief education-based intervention can increase clinician use of MBC within a PC-MHI setting. Meaningful use of MBC to inform treatment was not evaluated in this QI project and is an area for future investigation.

In recent years, several Micro Health Insurance (MHI) schemes have been initiated in low- and middle-income countries (LMIC) to meet the universal health coverage targets. Evidence on the utilization of these MHI schemes is scarce. Field experiences and lesson learning is crucial to effectively increase access to health care and offer protection against catastrophic health expenditure to the poorest population through the MHI schemes. This paper analyzes community utilization and factors affecting utilization of an MHI provided to the poorest rural households in eight districts of Sindh province of Pakistan. This initiative is part of a larger pro-poor European Union (EU) funded Sindh Union Council and Community Economic Strengthening Support (SUCCESS) Programme implemented by the Rural Support Programs (RSPs). The analysis draws on insurance utilization records and an internal assessment report by the RSPs Network (RSPN). The analysis provides qualitative experiences of the community, empanelled health care providers, the insurance agency and frontline management staff. Our analysis revealed that the overall utilization was very low (0.42%) and the highest number of cases treated at the hospital were of women utilizing obstetric and gynaecology related care. The scheme was noted to prevent catastrophic health expenditure in households that were able to successfully utilize the scheme. Key factors affecting utilization were identified to be around i) awareness creation, ii) distance to empanelled hospitals, and iii) access issues at the health facility level. We aim to add to the knowledge base around MHI for policy makers to design and implement more informed initiatives in the future.

Oral health is indeed a challenge for the urban poor. Majority of the patients spend from their pocket, which aggravates their financial condition. It is paramount for the government and the healthcare industry to adopt a value-based approach to redress the oral health lapses for the underserved population. Micro health insurance (MHI) can have a game changing effect on the oral healthcare space too, if concerned stakeholders build the right partner network. Aim of the study was to discuss the principal features, basic structure, and functioning of a few MHI schemes, and presents a hypothetical model of MHI which can be implemented in dentistry. Literature search was conducted in two main databases, pubmed and cochrane, using key phrases such as “community based health insurance,” “micro health insurance,” micro or community based health insurance,” and “health insurance and financial protection”. Articles published in last ten years with full texts were considered. 23 schemes were eligible for the systematic review. Our analysis shows that MHI, in the majority of cases, contributes to the financial protection of its beneficiaries, by reducing out of pocket health expenditure, catastrophic health expenditure, household borrowings and poverty. However, the studies did not affirm oral health benefits. The importance of oral healthcare in India is superficial. Focus on oral healthcare can be achieved only if the impending cost due to out of pocket payments can be supplanted with a more affordable and dynamic payment model. With MHI extended to oral healthcare, India can certainly achieve its SDG goal. It’s time to look beyond.

ObjectivesResearch suggests that military personnel frequently delay disclosing mental health issues and illness (MHI), including substance use disorder, to supervisors. This delay causes missed opportunities for support and workplace accommodations which may help to avoid adverse occupational outcomes. The current study aims to examine disclosure-related beliefs, attitudes and needs, to create a better understanding of personnel’s disclosure decision making.DesignA cross-sectional questionnaire study among military personnel with and without MHI. Beliefs, attitudes and needs regarding the (non-)disclosure decision to a supervisor were examined, including factors associated with (non-)disclosure intentions and decisions. Descriptive and regression (logistic and ordinal) analyses were performed.SettingThe study took place within the Dutch military.ParticipantsMilitary personnel with MHI (n=324) and without MHI (n=554) were participated in this study.Outcome measure(Non-)disclosure intentions and decisions.ResultsCommon beliefs and attitudespro non-disclosurewere the preference to solve one’s own problems (68.3%), the preference for privacy (58.9%) and a variety of stigma-related concerns. Common beliefs and attitudespro disclosurewere that personnel wanted to be their true authentic selves (93.3%) and the desire to act responsibly towards work colleagues (84.5%). The most reported need for future disclosure (96.8%) was having a supervisor who shows an understanding for MHI. The following factors were associated both with non-disclosure intentions and decisions: higher preference for privacy (OR (95% CI))=(1.99 (1.50 to 2.65)intention, 2.05 (1.12 to 3.76)decision) and self-management (OR (95% CI))=(1.64 (1.20 to 2.23)intention, 1.79 (1.00 to 3.20)decision), higher stigma-related concerns (OR (95% CI))=(1.76 (1.12 to 2.77)intention, 2.21 (1.02 to 4.79)decision) and lower quality of supervisor–employee relationship (OR (95% CI))=(0.25 (0.15 to 0.42)intention, 0.47 (0.25 to 0.87)decision).ConclusionTo facilitate (early-)disclosure to a supervisor, creating opportunities for workplace support, interventions should focus on decreasing stigma and discrimination and align with personnels’ preference for self-management. Furthermore, training is needed for supervisors on how to recognise, and effectively communicate with, personnel with MHI. Focus should also be on improving supervisor–employee relationships.

Object. The aims of this study were to analyze the relevance of risk factors in mild head injury (MHI) by studying the possibility of establishing prediction models based on these factors and to evaluate the reliability of the clinical guidelines proposed for the management of MHI. Methods. A series of 1101 patients with MHI were prospectively enrolled in this study. In all cases clinical data were collected and a computerized tomography (CT) scan was obtained. The relationship between clinical findings and the presence of intracranial lesions was studied to establish prediction models based on logistic regression and recursive partitioning analysis. Recently proposed guidelines and recommendations for the treatment of MHI were selected, calculating their diagnostic efficiency when applying each of them to our series. The incidence of acute intracranial lesions was 7.5% (83 patients). A Glasgow Coma Scale score of 14, loss of consciousness, vomiting, headache, signs of basilar skull fracture, neurological deficit, coagulopathies, hydrocephalus treated with shunt insertion, associated extracranial lesions, and patient age greater than 65 years were identified as independent risk factors. Prediction models built on clinical variables were able to indicate patients with clinically important lesions, but failed to achieve 100% sensitivity in the detection of all patients with CT scans positive for intracranial lesions within reasonable specificity limits. Conclusions. Clinical variables are insufficient to predict all cases of intracranial lesions following MHI, although they can be used to detect patients with relevant injuries. Avoiding systematic CT scan indication implies a rate of misdiagnosis that should be known and assumed when planning treatment in these patients by using guidelines based on clinical parameters.

Zusammenfassung Einleitung Der Gemeinsame Bundesausschuss (G-BA) hat im Jahr 2015 eine Richtlinie zu minimalinvasiven Herzklappeninterventionen (MHI-RL) beschlossen. Krankenhäuser haben demnach jährlich die Erfüllung der Qualitätsanforderungen der Richtlinie in Form von Checklisten gegenüber den Sozialleistungsträgern zu erklären. Diese können die Angaben durch den Medizinischen Dienst der Krankenversicherung (MDK) vor Ort überprüfen lassen. Es wird über die Erfahrungen mit diesen Prüfungen in hessischen Krankenhäusern berichtet. Methode Beim MDK Hessen werden nach Beauftragung durch die Sozialleistungsträger und entsprechender Ankündigung die Prüfungen von 2 ärztlichen Fachgutachtern im Rahmen von Begehungen vor Ort in den Krankenhäusern durchgeführt. Ergebnisse Seit dem Inkrafttreten der MHI-RL wurden bei 12 hessischen Krankenhäusern 33 Qualitätsprüfungen zur kathetergestützten Aortenklappenimplantation (TAVI) und/oder transvenösen Clip-Rekonstruktion der Mitralklappe (TMVR/„MitraClip®“) durchgeführt. Im Rahmen einer ersten Prüfung konnte in 87,5% der Krankenhäuser, die TAVI und TMVR durchführen, und in 50,0% der ausschließlich TMVR durchführenden Krankenhäuser eine Übereinstimmung mit den Checklisten nachvollzogen werden. Im Fall einer Nichterfüllung konnte in allen Fällen im Nachgang der Erstprüfung innerhalb der jeweils mit den Sozialleistungsträgern vereinbarten Frist die Erfüllung bestätigt werden. Bis zum Stichtag 21.03.2017 konnte in 11 der 12 überprüften und seit März 2018 in allen 12 Krankenhäusern die Anforderungen der MHI-RL als erfüllt beurteilt werden. Schlussfolgerungen Seit Inkrafttreten der MHI-RL erfolgt konsequent eine Beauftragung des MDK Hessen als unabhängige und unparteiische sozialmedizinische Sachverständigeninstitution innerhalb der gesetzlichen Krankenversicherung. Mit den Qualitätsprüfungen leistet er einen wichtigen Beitrag zur Qualitätssicherung der spezialisierten stationären Versorgung in Hessen. Dies hat zu einer flächendeckenden Erfüllung der Qualitätsvorgaben der MHI-RL in Hessen geführt. Aufgrund dieser Erfahrungen ist der MDK Hessen gut für die Herausforderungen der zukünftigen MDK-Qualitätskontroll-Richtlinie/MDK-QK-RL gerüstet.

Age is variably described as a minor or major risk factor for traumatic intracranial lesions after head injury. However, at present, no specific CT decision rule is available for elderly patients with minor head injury (MHI). The aims of this prospective multicenter cohort study were to assess the performance of existing CT decision rules for elderly MHI patients and to compare the clinical and CT characteristics of elderly patients with the younger MHI population. Thirty-day mortality between two age groups (cutoff ≥ 60 years), along with clinical and CT characteristics, was evaluated with four CT decision rules: the National Institute for Health and Care Excellence (NICE) guideline, the Canadian CT Head Rule (CCHR), the New Orleans Criteria (NOC), and the CT Head Injury Patients (CHIP) rule. Of the 5517 MHI patients included, 2310 were aged ≥ 60 years. Elderly patients experienced loss of consciousness (17% vs. 32%) and posttraumatic amnesia (23% vs. 31%) less often, but intracranial lesions (13% vs. 10%), neurological deterioration (1.8% vs. 0.2%), and 30-day mortality (2.0% vs. 0.1%) were more frequent than in younger patients (all p < 0.001). Elderly patients with age as their only risk factor showed intracranial lesions in 5% (NOC and CHIP) to 8% (CCHR and NICE) of cases. The sensitivity of decision rules in the elderly patients was 60% (CCHR) to 97% (NOC) when age was excluded as a risk factor. Current risk factors considered when evaluating elderly patients show lower sensitivity to identify intracranial abnormalities, despite more frequent intracranial lesions. Until age-specific CT decision rules are developed, it is advisable to scan every elderly patient with an MHI.

Ekosistem mangrove memiliki peranan penting bagi eksistensi dan penyediaan jasa ekosistem kepada masyarakat di pulau kecil. Fungsionalitas mangrove sangat tergantung dari ukuran, struktur komunitas dan kualitas ekosistem. Penelitian tentang penilaian kualitas struktur komunitas mangrove pulau kecil telah dilakukan di Pulau Middleburg-Miossu sebagai rangkaian dari Ekspedisi Nusa Manggala 2018. Penelitian ini bertujuan untuk menganalisis struktur komunitas dan indeks kesehatan mangrove (MHI) mangrove di pulau tersebut yang dihubungkan dengan indeks-indeks vegetasi berbasis penginderaan jauh. Lokasi penelitian dibagi menjadi empat zona, dimana hasil penelitian menunjukkan bahwa zona terdepan didominasi oleh jenis Sonneratia alba (INP 263,32%) dengan persentase tutupan kanopi < 50%, ukuran diameter > 20 cm dan ketinggian tegakan yang lebih rendah. Sementara itu, tiga zona lainnya ke arah darat, didominasi oleh jenis Ceriops tagal dengan persentase tutupan kanopi >80%, serta kerapatan pancang yang cukup tinggi. Secara keseluruhan, kondisi kesehatan mangrove di lokasi penelitian termasuk dalam kategori sedang/cukup baik dengan rentang nilai MHI 38,7-60,7%. Kombinasi indeks vegetasi NBR, GCI, SIPI dan ARVI menunjukkan nilai koefisien regresi yang paling tinggi untuk memprediksi nilai MHI, yaitu 0,831, berdasarkan analisis AIC. Interpolasi nilai MHI berdasarkan model regresi linier terbaik menunjukkan bahwa 6,56 ha mangrove di lokasi penelitian atau 40.74% termasuk dalam kategori sehat.

The objective of this work is to assess the potential of the atmospheric water harvesting (AWH) by direct cooling under the climate of Thailand. The assessment was considered from water scarcity, meteorological data and engineering analysis, including moisture harvesting index (MHI), water capability and energy cost. The meteorological data between 2012-2021 were used as primary data for engineering analysis. The results showed that Thailand has the potential to supply freshwater by using AWH with direct cooling. The average MHI of Thailand is 0.548 which is comparable with high potential of global assessment. 71 cities from 77 cities in Thailand have MHI over 0.50, which is the favorable condition for AWH by direct cooling. From the calculation under Thailand conditions, the water harvesting rates by direct cooling could be in the range of 0.97-1.30 L/h with energy costs as low as 0.047 USD/L for 71 cities in Thailand.

Abstract This research aimed to explore, isolate, select, and characterize lactic acid bacteria (LAB) potentially used as amylolytic bacteria from traditional fermented food “dadih”. Dadih was collected from Lareh Sago Halaban and Lintau, West Sumatera Province. The LAB was isolated by the streak method to obtain a uniform color and size colonies. The selected isolates were characterized by the reaction gram and catalase test. The result showed that isolates had the form of coccus, coccobacillus, and basil with gram-positive, catalase-negative, and endospore-negative reactions. The further characterization using the KIT API 50 CHL identified Lactobacillus plantarum (mH1), Lactobacillus paracasei ssp paracasei (mL3), Lactobacillus plantarum (mH4), Lactococcus lactis subsp lactis (mH6), Lactobacillus plantarum (mH7), Lactobacillus plantarum (mH8), Lactobacillus brevis (mH13), and Lactobacillus paracasei subsp paracasei (mL14). The amylolytic and starch hydrolysis test showed that the isolates with higher amylolytic index ≥2 were Lactobacillus paracasei ssp paracasei mL3, Lactobacillus plantarum mH4, and Lactobacillus paracasei ssp paracasei mL14. The Lactobacillus plantarum mH8 had a lower amylolytic index of 0.7. Therefore, the four isolates (mL3, mH4, mL14, and mH8) are potentially used as fermenting bacteria for high- carbohydrate food.
