Abstract:
ObjectiveTo evaluate procedure utilization patterns for vertebroplasty and kyphoplasty in the US Medicare population from 2004 to 2014.MethodsThe analysis was performed using the Centers for Medicare and Medicaid Services database of specialty utilization files for the fee for service (FFS) Medicare population.ResultsThe FFS Medicare population increased by 28% with an annual increase of 2.5% from 2004 to 2014. Utilization of vertebroplasty procedures decreased by 63% with an average annual decrease of 9.5% from 2004 to 2014 per 100 000 FFS Medicare beneficiaries. During the same time period, kyphoplasty procedures decreased by a total of 10%, with an average annual decrease of 1.3%. For augmentation generally (combined vertebroplasty/kyphoplasty data) there was thus an overall decrease in the rate per 100 000 Medicare population of 32% from 2004 to 2014, with an average annual decrease of 4.8%. The majority of vertebroplasty procedures were performed by radiologists whereas the majority of kyphoplasties were performed by orthopedic surgeons and neurosurgeons.ConclusionsThere has been a significant decline in vertebroplasty and kyphoplasty procedures in the FFS Medicare population between 2004 and 2014.

Abstract:
We propose a novel and easy-to-implement approach to detect potential overbilling based on the hours worked implied by the service codes which physicians submit to Medicare. Using the Medicare Part B Fee-for-Service (FFS) Physician Utilization and Payment Data in 2012 and 2013 released by the Centers for Medicare and Medicaid Services, we construct estimates for physicians' hours spent on Medicare beneficiaries. We find that about 2,300 physicians, representing about 3 percent of those with 20 or more hours of Medicare Part B FFS services, have billed Medicare over 100 hours per week. We consider these implausibly long hours. (JEL H51, I13, I18, J22)

Abstract:
Background and Objective Acquired thrombotic thrombocytopenic purpura (aTTP) is a rare hematologic disorder that causes microvascular thromboses and can lead to serious and life-threatening medical complications. The aim of this study was to describe aTTP-related resource utilization, cost, complications, and overall survival (OS) among US Medicare and non-Medicare populations following aTTP episodes. Methods This retrospective study utilized administrative claims data for Medicare Fee-for-Service (FFS) beneficiaries (100% sample) and a sample of commercial, managed Medicaid [MM], Medicare Advantage [MA] plan members from the Inovalon MORE2 Registry. Patients aged 18+ with aTTP were identified using a validated algorithm (Wahl et al, 2010): ≥1 hospitalization for thrombotic microangiopathy + therapeutic plasma exchange (TPE) between 2010 and 2018. Patients with hemolytic-uremic syndrome or other conditions mimicking aTTP during same hospitalization were excluded. Outcomes included characterization of index hospitalization (including length of stay), diagnosis-related group (DRG) payment amount (2019 US$ [Medicare payments also included outlier payments]), and risk of mortality. OS was compared for Medicare FFS patients with aTTP to a 1:1 matched cohort of Medicare FFS beneficiaries without aTTP (matched on age, gender, region, index year, socioeconomic status, disability insurance benefits, and Charlson comorbidity index score). Median survival time and 1-year/2-year survival rates were estimated using Kaplan Meier methodology and hazard ratio was obtained using Cox proportional hazard model. In a subgroup analysis of aTTP patients across payer channels with at least 6 months of baseline and 1 month of follow-up data, percentage of patients with readmission for TPE (exacerbation if <30 days post-discharge; relapse if >30 days post-discharge) and rate of post-discharge clinical complications per 100 person-years was calculated. Results During the 9-year period, 2,279 patients met the study criteria for aTTP; 65.2% (N=1,486) were enrolled in Medicare FFS: 13.6% (N=312) in commercial, 15.7% (N=358) in MM, and 5.4% (N=123) in MA. Mean (SD) age (in years) varied by payers as expected: Medicare FFS: 65.9 (13.9); MA: 63.8 (13.6); commercial: 45.0 (14.3); MM: 37.5 (14.0). Mean (SD) hospitalization for index event ranged from 12.4 (9.4) to 15.8 (11.8) days; majority of patients required intensive care (Medicare FFS: 61.4% [mean (SD) ICU days: 8.3 (8.2)]; MA: 61.8%; commercial: 62.2%; MM: 60.1%). Among Medicare FFS patients, 15.7% died during initial hospitalization and 21.0% died within first 30 days of the event (mean (SD) time to death: 11.7 (7.2) days). Among matched cohorts of Medicare patients with and without aTTP (N=833 in each cohort), OS was lower for patients with aTTP (Figure 1). Specifically, 1-year survival rates among aTTP patients was 71.8% (95% CI: 68.6%-74.8%) vs. 95.6% (94.0%-96.8%) for those without aTTP. Two-year survival rates among aTTP patients was 66.6% (63.2%-69.8%) vs. 91.1% (88.8%-92.9%) for those without aTTP. Risk of mortality was 2.9 times higher for patients with aTTP vs. without aTTP (95% CI: 2.4-3.4). Mean (SD) DRG payment for index hospitalization varied by payers: Medicare FFS: $29,024 ($32,565); MA: $12,860 ($6,981); commercial: $9,996 ($5,995); MM: $10,470 ($7,370). During follow-up, 18.4%-22.4% of patients experienced aTTP-related exacerbation [Medicare FFS: 18.4%; MA: 21.9%; commercial: 22.4% and MM: 22.2%]. Annual incidence rate of relapse per 100 person-years was 5.6 [Medicare FFS: 3.6; MA: 8.7; commercial: 10.4 and MM: 14.7] and annual incidence rate of complications per 100 person-years was 16.7 [Medicare FFS: 15.5; MA: 20.5; commercial: 21.7 and MM: 19.1]. Conclusions This is the first real-world study evaluating burden of illness among aTTP patients in the US across payer types. Despite being treated with TPE, patients with aTTP have high acute mortality and are nearly three times as likely to die compared with the general Medicare population without aTTP. During the initial hospitalization, many required intensive care. Following discharge, approximately 1 in 5 was readmitted within 30 days and had higher incidence for clinical complications associated with aTTP. The study findings highlight the need for more effective therapies to reduce disease burden for this population.

Abstract:
Background: The cost of US health care continues to increase, with treatments related to low back and neck pain and other musculoskeletal disorders accounting for the third highest amount of various disease categories. Interventional techniques for managing pain apart from conservative modalities and surgical interventions, have generally been thought to be growing rapidly. However, a recent analysis of utilization of interventional techniques from 2000 to 2016 has shown a modest decline from 2009 to 2016, compared to 2000 to 2009. Objectives: The objectives of this analysis include providing an update on utilization of interventional techniques in managing chronic pain in the Medicare population from 2009 to 2018 in the fee-for-service (FFS) Medicare population of the United States. Study Design: Utilization patterns and variables of interventional techniques in managing chronic pain were assessed from 2000 to 2009 and from 2009 to 2018 in the FFS Medicare population of the United States. Methods: The data for the analysis was obtained from the master database from the Centers for Medicare & Medicaid Services (CMS) physician/supplier procedure summary from 2000 to 2018. Results: The analysis of data showed that there was a decline in utilization of interventional techniques from 2009 to 2018 of 6.7%, with an annual decline of 0.8% per 100,000 FFS Medicare population, despite an increase of 0.7% per year of population growth (3.2% of those 65 years or older) and a 3% annual increase in Medicare participation from 2009 to 2018. Medicare data from 2000 to 2009 showed an increase of 11.8% per year per 100,000 individuals of the Medicare population. The 2009 to 2018 data also showed a 2.6% annual decrease in the rate of utilization of epidural and adhesiolysis procedures per 100,000 population of FFS Medicare, and a 1% decrease for disc procedures and other types of nerve blocks, while there was an increase of 0.9% annually for facet joint interventions and sacroiliac joint blocks. Limitations: Limitations of this analysis include: only the Medicare population was utilized, and among the Medicare population, only the FFS population was evaluated; utilization patterns in Medicare Advantage Plans, which constitutes almost 30% of the population were not considered. Further, the utilization data for individual states was sparse and may not be accurate. Conclusion: The decline in utilization of interventional techniques continued from 2009 to 2018 with 6.7% per 100,000 Medicare population, with an annual decline of 0.8%, despite an increase in the population rate and Medicare enrollees of 0.7% and 3% annually.

Abstract:
e12615 Background: Patients with invasive or in-situ breast cancers may increasingly be offered bilateral mastectomy with reconstruction with a view towards achieving symmetry and risk reduction. We investigated whether this treatment option was offered equally based on race and insurance status. Methods: Rates of mastectomy and reconstruction were studied among 4703 patients diagnosed or treated at Ascension St John Hospital, Ascension Macomb Oakland Hospital, and Ascension Providence Hospital between 2005 and 2015. Data collected included demographics, tumor characteristics, insurance (primary payer), first course of surgical treatment, vital status, and cause of death. Cases coded as contralateral mastectomy and reconstruction were considered as representative of “bilateral mastectomy” and reconstruction. Results: Insurance status could be definitively categorized as HMO/PPO, fee for service (FFS), Medicare, or Medicaid in 2375 breast cancer patients. Medicaid HMO was categorized as Medicaid and Medicare with or without supplemental insurance was categorized as Medicare. For simplicity, cases coded as uninsured, other, and NOS were not analyzed further. A total of 406 of 2375 (17.0%) were coded as contralateral mastectomy with reconstruction. Smaller numbers of Medicare cases had contralateral mastectomy and reconstruction (7.3%) compared to 23.3% for HMO/PPO, 26.3% for FFS, and 16% for Medicaid, presumably related to older age. Within each insurance category, similar proportions of Caucasian and African American women were treated with contralateral mastectomy (Table) compared to all patients (Table). Conclusions: Patients having Medicaid insurance had lower rates of contralateral mastectomy and reconstruction compared to HMO/PPO and FFS cases. African American race did not appear to be associated with lower rates of this surgery within the Ascension St John, Ascension Macomb Oakland, and Ascension Providence hospitals. [Table: see text]

Abstract:
The prices that private insurers pay hospitals have received considerable attention in recent years, but most of that literature has focused on the commercially insured population. Although nearly one-third of Medicare beneficiaries are enrolled in a Medicare Advantage (MA) plan, little is known about the prices paid to hospitals by the private insurers that administer such plans. More information on the hospital prices paid by MA plans would provide additional insights into whether MA prices are more closely tied to Medicare fee-for-service (FFS) prices or commercial prices. Moreover, information on whether the hospital prices paid by MA plans vary with market characteristics or other factors would be useful for evaluating the performance of the MA program and analyzing proposals to modify it. In this study, we compared the hospital prices paid by MA plans and commercial plans with Medicare FFS prices using 2013 claims from the Health Care Cost Institute (HCCI) database. The HCCI claims were used to calculate hospital prices for private insurers, and Medicare’s payment rules were used to estimate Medicare FFS prices. We focused on stays at acute care hospitals in metropolitan statistical areas (MSAs). We found MA prices to be roughly equal to Medicare FFS prices, on average, but commercial prices were 89% higher than FFS prices. In addition, commercial prices varied greatly across and within MSAs, but MA prices varied much less.

Abstract:
Background: The increase in the utilization of various techniques in managing chronic pain, including interventional techniques, is a major concern for policy-makers and the public at large. Consequently, multiple regulations have been instituted to reduce health care expenditures in general and expenditures related to interventional techniques in particular. Previous investigations have shown significant increases of utilization of interventional techniques across the board with minor decreases noted in 2007, 2010, 2012 and 2013. Objective: To assess the patterns of utilization of interventional techniques in chronic pain management in the fee-for-service (FFS) Medicare population. Study Design: Analysis of utilization patterns of interventional techniques from 2000 to 2014 in Fee-for-Services (FFS) Medicare beneficiaries in managing chronic pain. Methods: The analyzed data was derived from the Centers for Medicare and Medicaid Services (CMS) Physician/Supplier Procedure Summary Master Data from 2000 to 2014. Results: The analysis of data from 2000 to 2014 in FFS Medicare beneficiaries showed overall utilization of interventional techniques increasing at a rate of 153% and an annual average growth rate of 6.9% per 100,000 Medicare population with increase in services of 242%. This showed a 3% decrease per 100,000 Medicare population, compared to the data from 2000 through 2013, even though services increased by 6% due to the increase in the number of Medicare recipients in the FFS beneficiary group. The overall increases in epidural and adhesiolysis procedures were 165% with a rate of 96% per 100,000 Medicare population with an average annual increase of 4.9%. Facet joint interventions and sacroiliac joint blocks increased at a rate of 313% per 100,000 population with an annual average increase of 10.7%. Disc procedures and other types of nerve blocks increased at a much lesser pace than epidural and adhesiolysis procedures or facet joint interventions with an increase of 54% per 100,000 Medicare population and annual increase of 3.1%. A decrease in utilization was noted in 5 of 14 years ranging from 1.2% to 3.8%. Limitations: The limitations of this updated utilization patterns of interventional techniques in managing chronic pain are multiple with lack of inclusion of participants from Medicare Advantage Plans, lack of complete and accurate data for statewide utilization, and potential errors in coding, billing, and documentation. Conclusion: This overall analysis of patterns of utilization in managing chronic pain with interventional techniques showed a continued and significant increase in FFS Medicare beneficiaries from 2000 to 2014 with an increase of 153% per 100,000 Medicare population and at a rate of 6.9% on average per year. However, there were decreases of 2.9% in 2007, 3.8% in 2010, and 1.3%, 3.4%, and 1.2% from 2012 to 2014.

Abstract:
Abstract Introduction: Population-based cancer registries, such as the National Cancer Institute Surveillance, Epidemiology and End Results (SEER) program and the North American Association of Central Cancer Registries (NAACCR) are the largest sources of information for cancer epidemiology and statistics. The most recent acute myeloid leukemia incidence estimate from SEER (2011) is 17.5 per 100,000 (N=7,245) among the US ≥65 year-old population; however, recent studies suggest these registries may underreport cancer rates due to reasons including sequencing of diagnoses and inpatient reporting requirements. For cancers such as myelodysplastic syndrome (MDS) and acute and chronic myeloid leukemia (AML & CML), this is concerning as they are more likely to occur after initial diagnosis of other cancers. A recent study independently calculated MDS, AML and CML cases from 2000-2005 using a Medicare claims-based algorithm and concluded that SEER and NAACCR failed to capture a substantial number of cases and the true incidence was 50-75% greater than reported (Cogle, et al., 2012). Updated AML epidemiology statistics outside of SEER and NAACCR have not been published. Objective: To employ a Medicare claims-based algorithm to estimate gender- and age-specific AML incidence and prevalence among the 2012 US Medicare fee-for-service (FFS) population. Methods: A retrospective analysis of claims using 2012 Centers for Medicare and Medicaid Services (CMS) data included an Institutional sample (100%) and random Non-Institutional Carrier samples (5%) which together represented the healthcare utilization of Medicare Part A & B (Medicare FFS) beneficiaries. AML diagnoses were identified using ICD-9 codes and AML treatments identified using HCPCS J Codes and ICD-9 infusion codes. Prevalent AML patients were defined as having ≥2 AML diagnoses associated with medical claims OR 1 AML medical claim and 1 AML treatment. A sub-population of all prevalent AML patients without historical AML diagnoses or treatments during the prior 2 years were identified as new (incident) AML patients.Analyses were computed by gender and two age-cohorts (<65 and ≥65 years old). Patients in the Institutional 100% dataset were considered census and no weighting was required but appropriate weights were used to project the 5% random carrier sample (<9% of AML patients) to the Medicare FFS population. Results: Of 34.2 million Medicare FFS beneficiaries, 15,976 had AML, a prevalence rate of 0.05% (Table). Most were ≥65 years old (N=11,936; 75%) and prevalence did not vary between age groups; however, women ≥65 years old had a significantly lower prevalence than men ≥65 years old (0.03% vs. 0.06%; z=31.2, p<.001) as men were nearly twice as likely to be diagnosed with AML (RR=1.86, 95% CI: 1.78, 1.95). There were no gender differences in incidence among younger patients (18.6 per 100,000 for men vs. 18.4 per 100,000 for women). A high proportion of AML patients were newly diagnosed (N=9,074; 57%). Conclusions : Our AML incidence estimate for the ≥65 year Medicare FFS cohort of 29.0 per 100,000 (N=7,582) is substantially higher than incidence estimate reported by SEER for this age group. As only 70-80% of the ≥65 year-old population is covered under Medicare FFS, the total number of ≥65 incident patients is likely higher than reported by SEER. Registries may be underreporting AML due to methodological differences. Furthermore, the 15,976 prevalent patients in Medicare FFS alone may be much higher than previously known. Claim-based algorithms may provide higher AML estimates than current SEER methodology. Further research should investigate claims data in the remaining ≥65 year-old population covered under Medicare Advantage and a younger, non-Medicare FFS population sample more representative of persons <65 years of age.

Abstract:
238 Background: Care experience ratings are recognized as measures of quality. We introduce a new resource, SEER-CAHPS, linking cancer registry data from the National Cancer Institute’s Surveillance, Epidemiology and End Results (SEER) program with Medicare claims and the Medicare Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey. Methods: The SEER-CAHPS data resource includes registry data from 1973-2011 (diagnosis, incidence, mortality, and sociodemographic data), Medicare CAHPS survey data from 1998-2013 (sociodemographic, health status, and care experience ratings), and Medicare fee-for-service (FFS) claims data from 2002-2013. SEER-CAHPS includes global ratings of overall care, personal doctor, specialist, health plan, and prescription drug plan and composite ratings of doctor communication, care coordination, getting needed care, and getting care quickly. The data also contain optional survey weights to account for the Medicare CAHPS sampling design. Results: Currently, SEER-CAHPS includes 205,339 individuals with a history of cancer documented in SEER (FFS: 26,802 with a survey before cancer diagnosis, and 55,231 with a survey after cancer diagnosis; Medicare Advantage [MA]: 57,227 with a survey before cancer diagnosis and 71,436 with a survey after cancer diagnosis). The database also includes 724,965 MCAHPS respondents without cancer in SEER regions (FFS: 282,592; MA: 447,358). The data provide insights on topics including experiences of cancer patients in their last year of life; experiences of cancer survivors; experiences of dually eligible (Medicare-Medicaid) cancer patients; and the associations of guideline-concordant follow-up care with patient experiences among people with colorectal cancer. We will demonstrate project sample-size estimation and present instructions for submitting data access applications. Conclusions: SEER-CAHPS provides population-based, cancer-specific data on patient experiences and associations with both health outcomes and healthcare utilization.

Abstract:
Gaps in knowledge and systematic tracking of the prevalence of intellectual and developmental disabilities (IDD) and characteristics that may affect the health of this disability group limits our ability to address the health disparities they experience in comparison to people without disability. The purpose of this study is to begin to fill one relevant critical gap in knowledge: understanding the demographics and health outcomes of adults with IDD who receive services under Medicare Fee-for-Service (FFS), many of who are also eligible for Medicaid. Using 2016 Medicare administrative claims, we examined the prevalence and characteristics of five diagnosis groups of IDD, in those under 65 and those 65 and over, as well as their health outcomes. We found that the IDD Medicare FFS group had high prevalence rates for chronic physical and mental health conditions, overuse of emergency departments, and high rate of 30-day readmission. These findings highlight the need for evidence-based health care coordination, improved and increased public health interventions, and continued surveillance.

Abstract:
Current thinking suggests that preeclampsia is associated with activation of the maternal vascular endothelium in response to factors released from the placenta due to placental hypoxia. Failure of physiological modification of spiral arteries due to impaired trophoblast invasion results in a several-fold increase in the risk of developing pre-eclampsia and/or (IUGR). The defect behind impaired trophoblast invasion is not fully explained and the aetiological factor(s) linked with the development of pre-eclampsia, compared to normotensive IUGR, is not known. In this thesis, I examined placental and serum levels of fms-like tyrosine kinase I (sFltl) and placental growth factor (PIGF), as mediators of angiogenesis, and Fas and FasL, as mediators of apoptosis, in three groups; preeclampsia, normotensive IUGR and controls who had abnormal mid-trimester uterine artery Doppler. Uterine artery Doppler flows were examined in 553 women at 24 weeks. 97 of them had abnormal uterine artery Doppler flow and were enrolled in this study. 86 women were followed up; among them eight women developed preeclampsia and seven developed normotensive IUGR. Umbilical artery Doppler examination 24 hours before delivery in both groups, showed significantly lowered resistance indices in the preeclampsia compared to the normotensive IUGR group. I examined placental and serum levels of fms-like tyrosine kinase I (FIt I) and Placental Growth Factor (PIGF) in three groups. Soluble FItI acts as an antagonist for both Vascular Endothelial Growth Factor (VEGF) and PIGF. Placental FIt 1 and serum sFlt 1 were higher and serum PIGF was lower in the preeclampsia group compared to the other two groups. This could be responsible for the systemic manifestations of preeclampsia. This dysregulation in serum sFltl and PIGF was found as early as 24 weeks in pregnancies with abnormal uterine artery Doppler examination. The normotensive IUGR group had significantly elevated serum sFlU compared to controls. This could be due to an element of placental hypoxia in the IUGR group. To investigate the in-vivo effect of sFltl on impaired placental angiogenesis and trophoblast invasion, I examined the correlations between uterine artery Doppler resistance indices and serum sFIU and PIGF at 24 weeks. Significant correlations were found between these markers and uterine artery Doppler pulsatility index (pn and resistance index (Rn on both the placental and non-placental sides at 24 weeks. Fas and Fas ligand (FasL) are membrane proteins that mediate cellular apoptosis, and recently were related to cellular growth and migration. Using western blotting and immunohistochemistry, placental expression of Fas (western blotting) and (FasL) (immunohistochemistry) was assessed in the three study groups. No differences in placental Fas or Fas ligand were found between the groups. In addition, serum levels of Fas and FasL were measured at 24 weeks and within 24 hours of delivery in the same groups. Serum Fas was not different between the three study groups at 24 weeks and within 24 hours of delivery. Serum FasL was below the kit's detection threshold in the samples studied. In conclusion, placental FlU and its soluble form sFltl seem to play an important role in the pathophysiology of preeclampsia. In addition, sFltl correlated positively with the severity of impaired trophoblast invasion and could playa central role in blocking placental angiogenesis in these pregnancies. This needs further evaluation. Fas and FasL do not seem to have a role In impaired placentation and development of preeclampsia and IUGR.

Abstract:

When a family member is being cared for in palliative care relatives often need support to be able to support their family member. The purpose of the literature review was to illuminate the nursing staff’s support from the relatives’ perspective when a family member is being cared in a late palliative phase. The study is a literature review, there already existing research are surveyed. The findings were structured into two parts, tangible- and the intangible support. Tangible support is a one-way support; to receive information and that someone takes over. Intangible support is support within an interpersonal relation, when the nursing staff in one way or another respond to the relatives needs; that someone shows consideration, to be met with honesty, someone who gives time and to be given opportunity to feel hope. The support could make relatives feel secure and in control. Tangible- and intangible support are connected and form wholeness, but it is important to notice that there are two kinds of support and the relatives are in need of both.

This thesis addresses the problem of comfortable, low powered and, wireless solutions for specific body-worn sensing. The thesis discusses advantages and limitations of three different communication technologies for on body measurement and investigate methods to reshape sensors for optimum body-centric assessments. The RFID technology is considered one of the most influential solutions to overcome the limitated power consumption due to the presence of many sensors connected. Further, the Bluetooth low energy has been studied to solve security problems and reading distance that overall represent the bottleneck of the RFID for the body-worn sensors. Analog devices can drastically reduce the energy needs due to the sensors and the communications, considering few elements and a simple transmitting method. An entirely passive communication method, based on FSS is studied, enabling a reasonable reading distance with precise and reliable sensing capabilities, which has been discussed in this thesis. The objective of this thesis is to investigate multiple wireless technologies for wearable devices to identify suitable solutions for particular applications in medical fields. The first objective is to demonstrate the usability of the inexpensive battery-less technologies as a useful indicator of such a physio-pathological parameters by investigating the properties of the RFID tags. Furthermore, a more complex aspect regards the use of small passive components as wireless sensors for sleep diseases has been addressed. Lastly, an outcome of the thesis is to develop an entirely autonomous system using the BLE technology to obtain advanced properties keeping low power and a low price.

Full text
Abstract:
Functional electrical stimulation (FES) is a well-established approach that is employed as a therapeutic tool for the restoration of motor control in individuals experiencing muscle impairment. Although its use as a rehabilitation tool is validated by clinical results, current control approaches limit the full exploitation of its potential due to the lack of accuracy with which the FES is applied. Research has thus focused on the use of advanced, closed-loop control algorithms to provide more accurate FES that is both task-oriented, and matches the rehabilitation needs of the patient. Experimental results have been reported for a variety of control schemes. However, the majority of approaches have failed to transfer to clinical practice due to the difficulties associated with identifying a model of electrically stimulated muscle that adapts as the true plant varies with time. Estimation-based multiple model switched adaptive control (EMMSAC) is a robust control approach that has the potential to overcome the problems associated with the uncertain, time-varying properties of electrically stimulated muscle. EMMSAC utilises optimal disturbance estimation to assess the respective performances of a set of candidate plant models. Then the controller associated with the model that has best performance is switched into closed-loop operation. This thesis details the algorithmic modifications that allow disturbance estimation to be performed in the time-varying setting for nonlinear Hammerstein structures. Then it is shown experimentally that a general plant model set can be identified that represents the time-varying, FES-induced muscle activation dynamics for the population of younger healthy adults. This finding is exploited to design an EMMSAC controller that achieves accurate trajectory tracking for multiple participants with minimal prior model identification. Results indicate that the use of EMMSAC reduces RMS tracking error when compared with a fixed controller; similar results are also reported for older healthy participants. Furthermore, initial results for a small sample of stroke-participants are shown, which confirms the potential for the proposed control approach to be applied in a clinical setting for FES-based rehabilitation.

Abstract:
The aim of this master’s thesis is to interview school staff and pupils’ experiences and opinions of the FMS model in health prevention and promotion in one upper secondary school. This master´s thesis is based on qualitative data from three interviews, one individual interview with the principal of the school, and two focus interviews where there were one group from the school staff and one group with pupils. A semi-structured interview method was used. The interviews were recorded and transcribed word by word and analyzed with a qualitative content analysis. The analysis determines a theme where it was shown that FMS was a “Support for a meaningful school day and a better health”. The result contained two categories: Society accountableness and Content. The result show that FMS was a significant tool for both the principal, students and school staff. FMS made sure that the students got the possibility to work with structure and routine within their health work. Furthermore, FMS created relationships between both school personal as well as among students. In addition, FMS increased consciousness around health from a holistic perspective and created clarity around a good health. One important part of working with FMS was collaboration. In addition, the students wished that the school had an even bigger focus on health and helped them be free from performance anxiety. Moreover, the students had a wish about more health focus in school overall and they also wished for the FMS to be without encumbrance in the future. Their opinion today was that the students compared their results.    The FMS online tool, lifestyle plan, was easy to understand and work with.

Full text
Abstract:
The thesis work concerns X-ray spectrometry for both medical and space applications and is divided into two sections. The first section addresses an X-ray spectrometric system designed to study radiological beams and is devoted to the optimization of diagnostic procedures in medicine. A parametric semi-empirical model capable of efficiently reconstructing diagnostic X-ray spectra in 'middle power' computers was developed and tested. In addition, different silicon diode detectors were tested as real-time detectors in order to provide a real-time evaluation of the spectrum during diagnostic procedures. This project contributes to the field by presenting an improved simulation of a realistic X-ray beam emerging from a common X-ray tube with a complete and detailed spectrum that lends itself to further studies of added filtration, thus providing an optimized beam for different diagnostic applications in medicine. The second section describes the preliminary tests that have been carried out on the first version of an Application Specific Integrated Circuit (ASIC), integrated with large area position-sensitive Silicon Drift Detector (SDD) to be used on board future space missions. This technology has been developed for the ESA project: LOFT (Large Observatory for X-ray Timing), a new medium-class space mission that the European Space Agency has been assessing since February of 2011. The LOFT project was proposed as part of the Cosmic Vision Program (2015-2025).

Full text
Abstract:
Latensfasen är den första fasen i ett förlossningsarbete och är en normal process, trots detta är den komplex och svårdiagnostiserad. Det finns ingen direkt gräns mellan förvärkar och latensfasens början, däremot finns en tydligare beskrivning av när den aktiva fasen startar. Att latensfasen inte är väl definierad kan innebära problem för barnmorskor i deras möte med dessa kvinnor. En lång latensfas är relaterat till ett antal problem för den födande kvinnan, såsom trötthet, uppgivenhet, smärta, oro och olika förlossningskomplikationer. Även risken för interventioner ökar om kvinnan kommer in i ett tidigt skede till förlossningsavdelningen, och ännu inte är i aktivt fas. Syftet med studien är att belysa hur barnmorskan bedömer att kvinnan är i latensfas respektive aktiv fas. Metoden som använts är en enkätundersökning som har analyserats med kvalitativ innehållsanalys med deduktiv ansats. 78 barnmorskor som arbetar inom förlossningsvård i Göteborg samt Borås deltog i studien. De svarade på två öppna frågor om vilka parametrar de väger in i sin bedömning för att definiera latensfas respektive aktiv fas. I resultatet framkom att barnmorskorna beskriver 67 olika kriterier med små variationer för latensfasen som klassificerades i fem huvudkategorier. De definierade aktiv fas med 48 olika kriterier som även delades in i fem huvudkategorier. Huvudkategorierna delades in i underkategorier enligt analysprocess för kvalitativ innehållsanalys. I sammanställningen av resultatet visades sig att flertalet barnmorskor uppgav att oregelbundna värkar och ringa påverkan på livmodertappen är huvud- kriterier för latensfasen. Regelbundenhet och progress var huvudkriterier för aktiv fas. Tydligare riktlinjer är nödvändigt för att på allra bästa sätt hjälpa dessa kvinnor.

Full text
Abstract:
Technically-driven medical devices such as wireless implantable medical devices (WIMD) have become ubiquitous within healthcare. The use of these devices has changed the way nurses administer patient care. Consequently, the nursing workforce is large and diverse, and with it comes an expected disparity in personalities. Research involving human factors and technology acceptance in healthcare is not new. Yet due to the changing variables in the manner of which patient care is being administered, both in person and in the mechanism of treatment, recent research suggests that individual human factors such as personality traits may hold unknown implications involving more successful adoption of emerging technologies for patient care. The purpose of this research was to empirically investigate the influence of personality traits on a nurse’s intention to use WIMDs for patient care. One hundred and two nurses from a tertiary teaching hospital in Michigan were surveyed to determine if their identifiable personality traits statistically related to their intention to use a WIMD. A predictive model was developed by combining constructs from the unified theory of acceptance and use of technology (UTAUT) model and the Five Factor personality trait model (FFM). The model used moderated multiple regression (MMR) to statistically identify if the personality traits of openness, conscientiousness, extraversion, agreeableness, and neuroticism, moderated one or more statistically significant relationships between 1) performance expectancy (PE) and intention to use (IU), 2) effort expectancy (EE) and IU, 3) and social influence (SI) and IU. It was predicted that PE, EE, and SI would show statistical significance on a nurse’s IU of a WIMD when moderated by one or more of the five personality traits. Results showed statistical significance between PE and IU, and EE and IU, but not between SI and IU, when moderated by extraversion. Results showed no statistical significance between PE and IU, EE and IU, or SI and IU when moderated by openness, conscientiousness, agreeableness, or neuroticism. This research has contributed by conducting an investigation on individual human factors that may impact nurses’ intention to use emerging technologies; and by providing statistical evidence that may help to better predict the role personality traits have on a nurse’s adoption of WIMDs for patient care.

Full text
Abstract:
In this pilot study, a new avenue for exercise in tetraplegia, involving FES applied to upper limb muscles, is suggested. The main motivation for developing methods for FES-assisted arm-cranking exercise is to provide an exercise modality specifically designed for tetraplegia that might address cardiopulmonary issues, as well as work with remaining voluntary control of upper body musculature. One primary aim of this thesis was to determine the feasibility of using these systems in tetraplegia. To investigate this, standard protocols for exercise training, and incremental and constant-load exercise testing, were adapted to make them suitable for this population and this exercise modality. These novel protocols are described here, and represent one of the contributions of the thesis. The implementation of these protocols for an experimental evaluation of the proposed systems for FES-assisted arm-cranking exercise makes up the main part of the thesis. Five volunteers with tetraplegia participated in this experimental evaluation, and their data are presented as two main case studies, and additional case reports. The first outcome of thesis evaluation is that it shows the feasibility of the proposed methods for FES-assisted arm-cranking exercise training and testing in tetraplegia. Secondly, benefits of regular use of the systems are illustrated for some individuals with tetraplegia, based on key indicators of cardiopulmonary fitness and measures of upper limb strength. Thirdly, the limitations of the current set-up for FES-assisted arm-cranking exercise in higher level tetraplegia are identified. In summary, this thesis describes new systems and protocols for FES-assisted arm-cranking exercise in tetraplegia, and provides a preliminary assessment of these methods.

Abstract:
Effective techniques for the cryopreservation of human Adipose Stem Cells (ASCs) could increase the usefulness of these cells in tissue engineering and regenerative medicine. The traditional method of using fetal calf serum (FCS) and a chemical cryoprotectant like dimethylsulfoxide (DMSO) during freezing storage restricts the direct use of ASCs in regenerative medicine and reconstruction surgery. The objective of this study was to investigate the apoptotic, necrotic and viability response of ASCs frozen/thawed in the presence of a high molecular weight polymer, Polyvinylpyrrolidone (PVP) and in the absence of FCS. Post-freeze/thaw studies were also conducted to evaluate the effect of PVP on the in vitro osteogenic and adipogenic differentiation of ASCs. The results were compared with those obtained using the most commonly used cryopreservation media of 10%DMSO + 10% Dulbecco’s Modified Eagle Media (DMEM) + 80%FCS.

Abstract:
To match for complex product function and to solve insufficient computer aid for functional design, the Extended-Effect driven Function-Behavior-Structure (EE-FBS) model is constructed. A multi-flow and multi-pole effect model is presented by extending the one with single input/output flow in TRIZ. Four effect patterns and three reasoning methods are proposed to create effect chains. The FBS model is extended to an EE-FBS model based on effect through the description of the law of mapping overall function to external behavior, from external behavior to sub-behavior, etc. A functional design process was presented based on the EE-FBS model, and the computer-aided functional design software system is developed. A design example for functional design of Chinese dropping pill medicine demonstrates the proposed method is feasible.

Abstract:
Abstract In paraplegia due to complete or incomplete spinal cord injury, the connection from the brain to muscles in the lower limbs is severed but the muscles that act on signals from the brain to produce limb movement remain functional. Functional electrical stimulation (FES), which is the application of electric potential across a muscle group to artificially cause the muscle to contract, is a method that can be used alone or in conjunction with an orthosis to produce a gait cycle. Such FES based walking machines or devices have been studied and designed for several decades. However, their application in everyday exercise is limited by several factors, one of which is the rapid onset of muscle fatigue produced in the stimulated muscle. In this work, simulations were conducted in Simscape Multibody to lay the groundwork for the design of a next-generation FES based walking machine powered by the quadriceps femoris muscle group of each limb. The stimulation of the quadriceps femoris muscle causes the knee to extend while some energy is stored by the orthosis, which uses the stored energy to complete the gait cycle. In this study, we have analyzed the power requirements of each step in the hybrid FES-orthosis gait cycle for different stride lengths. These requirements can help identify small step sizes to reduce the power required from the stimulated muscle.

Abstract:
Introduction Virtual classroom training (VCT) is a novel educational method that permits accessible, distanced interactive expert instruction. We aimed to evaluate the efficacy of VCT in comparison to face-to-face training (FFT) and non-interactive computer-based learning (CBL) for basic surgical skills training. Methods 72 participants recruited from five London medical schools underwent stratified block randomisation into three equal intervention groups based on subjective and objective suturing experience. VCT was delivered via the BARCO weConnect platform and FFT was provided by expert instructors. Optimal student-to-teacher ratio was used, 12:1 for VCT and 4:1 for FFT. The assessed task was interrupted suturing with hand-tied knots. The primary outcome was post-intervention Objective Structured Assessment of Technical Skills (OSATS) score, adjudicated by two blinded experts and adjusted for baseline proficiency. Results VCT was non-inferior to FFT (adjusted difference 0.44, 95% CI: -0.54 to 1.75, delta 0.675), VCT was superior to CBL (adjusted difference 1.69, 95% CI 0.41 to 2.96) and FFT was superior to CBL (adjusted difference 1.25, 95% CI 0.20 to 2.29). FFT alone was associated with student travel expenses (mean £4.88, SD 3.70). Instructor hours used per student for VCT and FFT were 0.25 and 0.75, respectively. Conclusion VCT has a similar educational benefit to FFT and is a suitable modality of high-quality surgical skills education. VCT provides greater accessibility and resource efficiency compared to FFT. VCT satisfies the requirement for social distancing during the COVID-19 pandemic and is better than non- interactive CBL. VCT has the potential to improve global availability and accessibility of surgical skills training.

Abstract:
The development of an efficient and green catalyst can be considered as a major contribution for the esterification of free fatty acid (FFA) in non-edible oil feedstocks. The DES was encapsulated in medical capsules for esterification of free fatty acid. The DES was synthesized from allyltriphenylphosphonium bromide (Allyl) and p-toluenesulfonic acid (PTSA). The FFA content was reduced to < 2 % under optimum conditions (catalyst dosage 2% (wt/wt) catalyst to oil, 10:1 molar ratio of oil to methanol at 60 °C for 60 min reaction time). The formation of a eutectic mixture endows the catalyst with advantages for esterification reaction such as improvements in recyclability and hygroscopicity of PTSA.

Full text
Abstract:
A bioelectrical impedance analysis is a proven method to measure body composition in clinical situations. It uses the relation between the body fluid and the impedances in a variety of frequencies. A body model can be simplified as a parallel combination of a capacitor and two resistors which represent a cell membrane, Intracellular Fluid (ICF), and Extracellular Fluid (ECF). Low frequency current passes through ECF and high frequency current also passes through ICF in a body. A Cole-Cole plot is a graphical interpretation of the path of impedances and each axis represents resistance and reactance with variable frequencies. A high value of resistance in a horizontal axis is a resistance value of ECF and a low value of resistance at a high frequency presents ICF. Interpolation technique is needed to find out the exact cross-point between impedance values and the horizontal axis. The two estimated impedance values are used to derive Total Body Water (TBW), ICF, ECF, Fat Free Mass (FFM), and Fat Mass (FM) from various published equations [1]. Minimizing the possible error of fluid volume assessment and accurate prediction of fluid status in a human body is essential for appropriate therapy. Different techniques of fluid status assessment in a human body can be applicable, such as physical examination, orthostatic vital signs, blood volume measurement, acoustic cardiograph, chest radiography, and thoracic ultrasonography [2]. In this study, a bioelectrical impedance spectroscopy device and simple body models were used to collect data such as TBW, ICF, ECF, FM, and FFM. The ratio between ICF and ECF was investigated for the same values of TBW, FM, and FFM by varying impedance values.

Abstract:
Limited information exists about enrollment in Part D prescription coverage by Medicare beneficiaries with cancer. Part D coverage may increase access to medicines. This study evaluated patterns of Part D uptake and costs and assessed the effects of coverage on hospitalizations and emergency department (ED) use among people with colorectal cancer (CRC). We analyzed Surveillance, Epidemiology, and End Results (SEER)–Medicare linked data on fee-for-service (FFS) Medicare beneficiaries with at least 36 months of follow-up who were diagnosed with CRC at any point from January 2007 through December 2010, and a matched cohort of beneficiaries without cancer. Dual (Medicare/Medicaid) enrollees were excluded because they are automatically enrolled in Part D. Among beneficiaries with CRC (n=12,774), 39 percent had complete Part D coverage, defined as coverage in the diagnosis year and 2 subsequent years; the rate was 38 percent in the matched comparison cohort (P=.119). Among those with complete Part D coverage, there was no significant difference in annual prescription drug costs between people with CRC ($3,157, 95% confidence interval [CI]: $3,098–$3,216) and without ($3,113, 95% CI: $3,054–$3,172). Among people with CRC, odds of ED use ranged from unchanged to marginally higher for those with no or partial Part D coverage, (adjusted odds ratio: 1.09, 95% CI: 1.00–1.18), compared with those with complete Part D coverage. Lack of continuous Part D coverage was associated with more ED use among Medicare FFS beneficiaries with CRC in 2007–2013. Among people with Part D coverage, prescription drug costs varied little between those with CRC and matched beneficiaries without cancer.

Estimating financial cost to individuals with a food hypersensitivity. Food Standards Agency, December 2022. http://dx.doi.org/10.46756/sci.fsa.buq453.

Full text
Abstract:
The Food Standards Agency (FSA) is a non-ministerial government department within the United Kingdom responsible for protecting public health and protecting consumer interests in relation to food in England, Wales, and Northern Ireland. Food Hypersensitivities (FHS) is a key priority within the FSA as it is an important food-related health issue with a severe and enduring impact for people living with it. FHS includes individuals living with a food allergy, coeliac disease and food intolerance. It is the responsibility of the FSA to seek ways to understand and reduce avoidable deaths, the negative impact of FHS on both consumers and businesses, and make sure that FHS consumers have access to safe food that is what it says it is on the label, which they can trust. For people with chronic and / or potentially life-threatening FHS, that trust becomes even more important. FHS places both a public health and financial burden on society. According to the FSA’s Food and You 2 Wave 3 Survey(footnote 1), an estimated 800,000 people are living with a clinically diagnosed food allergy, 300,000 with coeliac disease and 1.2 million living with food intolerance and other FHS conditions in the UK. The FSA has invested in a programme of research to understand the economic and societal burden of FHS and to explore how people living with FHS are impacted in their daily lives. The FSA commissioned RSM UK Consulting (RSM), Dr Audrey DunnGalvin from University College Cork and Alizon Draper from the University of Westminster to quantify and monetise the financial burden imposed on people living with FHS through their day-to-day management of the physical risks associated with food allergies, food intolerance and coeliac disease. This is the first study of its kind to consider whether residents in England, Northern Ireland, and Wales who live with any type of FHS condition (food intolerance, coeliac disease or food allergy) results in additional financial burden for their household. About this study The aim of the study was to quantify and monetise the financial burden imposed on households with FHS through the day-to-day management of the physical risks associated with food allergies, food intolerance and coeliac disease, by: comparing the price paid for food between households with at least one adult above 18 years old living with FHS, to households without FHS valuing the direct costs incurred through efforts to manage FHS and remain symptom free (for example, medical and kitchen supplies) monetising indirect costs incurred when having to deal with an FHS condition (for example, lost working days) This study is unique in terms of estimating price differentials for food consumption across different types of FHS and then comparing to a non-FHS comparison group. Previous studies have focused on coeliac disease, specifically the comparison between gluten-free and gluten-containing products, so this study is adding new knowledge to the evidence base.
