Abstract:

Scriptlattes computational tool was used for extraction of performance indicators related to social responsibility, popularization and result prospection of research in nanotechnology in Brazil using as data source Plataforma Lattes and the CNPq Research Group Directory. Besides allowing for a quantitative evaluation of the bibliographic production on the matter, which used as base the number of published papers and book chapters, amongst other productions, the extractions have also allowed for the evaluation of indicators such as technological products, processes and techniques, related to the social responsibility in research, such as magazines and newspaper articles, linked to the popularization of Scientific results. Yet, the observation of indicators such as thesis and current research projects allowed the observation of prospective future results of current research in nanotechnology. Apart from the results related to the bibliographic productions, which can be found in several data basis, the tool makes available indicators in circular basis, which on turn, permit the prospect evaluation of future research results, as well as the evaluation of social responsibility and the popularization of research on the theme. The presented results may be replicated for any subject of interest, and may be used to guide future scientific research in the country.

Abstract:

The Tocantinzinho gold deposit, located in the Tapajós Mineral Province, Amazonia, Brazil, is considered the largest gold deposit in the region. It is a stockwork-disseminated gold deposit, hosted in a 1982 ± 8 Ma hydrothermalized monzogranite of the Creporizão Intrusive Suite, with petrographic and geochemical characteristics of volcanic arc to post-collisional granites. Gold is mainly associated with phyllic alteration. Primary fluid inclusions trapped in the mineralization stages are H2O–NaCl and unsaturated and homogenize either to the vapor or to the liquid with Th(t) of 300–430 °C, salinity of 2–16 wt % NaCl eq. and density from 0.43 to 0.94 g/cm3. At these conditions, Au is expected to be transported as Au(HS)2− complexes and ore is deposited as the result of boiling in the first mineralizing stages and of mixing between magmatic fluid and meteoric water during the phyllic alteration. Compared with other deposits, Tocantinzinho has similarities with magmatic-hydrothermal oxidized calc-alkaline granite-related gold deposits classified as porphyry gold deposits but we classify as a porphyry-style gold deposit, as it lacks some characteristics of the Phanerozoic porphyry-type deposits. The results from this study can be used to elaborate and guide prospection models in Amazonia and in similar Proterozoic terrains.

Abstract:

Aromatic and Medicinal Plants (AMP) represent a large part of biodiversity. However, in the absence of a detailed record of this diversity, research and AMP development projects are generally limited to a small portion of ethnobotanical heritage. To guide prospection, exploitation and conservation studies of the existing potential, a comprehensive evaluation of the natural diversity of AMP is required. The western Rif region in northern Morocco, which area represents less than 1% of national territory, is home to about 50% of the Moroccan floristic richness (2053 species and infraspecific taxa). This heritage includes 630 taxa from which only 23 are currently exploited and merely 57% are recognized by ethno-botanists. Among these assets, a list is drawn up containing 106 taxa with a special conservation status (very rare or rare taxa, and / or endemic and / or threatened) and some of which are widely exploited. From a phytosociological point of view and based on an available database of 449 floristic samples, natural forest stands and matorrals contain about 27% of all MAP of the study area. These AMP organize almost half the floristic composition of sclerophyllous forests (oleaster, kermes oak and cork oak forest) and about a third of the richness of each of the other groups analyzed (thermophilic formations, pure fir, limestone mountains forest, calcifuges deciduous, maritime pine, matorrals). Mountain groups are the richest in exclusive, endemic, rare and endangered AMP.

Abstract:

Geophysical methods are one of the best ways to determine the potential of a mining area. Indeed, for the prospection of metalliferous deposits, the magnetic method remains essential as it makes it possible to characterize the extent and the depth of the anomalous bodies present in the prospected zone, mainly due to their reaction with the values of the total magnetic field. Thus, for the manganese mining zone of Bouarfa and more exactly Hammraouet, the genesis of the deposit is such that the manganese is generally associated with ferruginous minerals and clearly affect the total magnetic field. That said, the raw results obtained must imperatively be subjected to corrections to only keep the effect of the anomalous bodies on the magnetic field. Hence, we must proceed with the correction of the daytime effect then we eliminate the regional effects to get the map of the residual anomaly and finally we perform a reduction to the pole that will allow us to have well individualized and unipolar anomalies and thus allowing us to locate precisely the potentially mineralized axes. The synthesis of the various maps obtained by spatial interpolation of the data recorded in situ and corrected allows us to locate areas of mining interest and to determine the different tectonic phenomena that took place in our study area. In time, these maps will serve us to guide the subsequent mechanical surveys to confirm the results obtained by geophysical methods.

Abstract:

The use of combustion in industrial activity is of paramount importance for economic and social development. However, combustion reactions are the main sources of atmospheric pollutant emissions. Given this reality, it is necessary to study new combustion techniques, such as the application of oxygen in the process, in order to increase the efficiency and productivity of the burning process and energy production. In addition, studies have reported the use of acoustic excitation, a low-investment technique that can promote higher rates of heat and mass transfer. Thus, the goal of this study was to bring data on the current scenario related to the application of these two technologies to the combustion process where, through the reported results, they can be used as a guide for companies’ decisions about new technologies and global trends to be identified. For this, a technological prospection was carried out which focused on patents to investigate the use of oxygen-enhanced combustion and acoustic excitation coupled to the combustion process; a total of 88 documents were found. Few documents applied acoustic excitation for process improvement, indicating that its use is recent; however, according to the literature, it is a promising field to be explored. Siemens AG was the main depositor, and ten primary inventors were identified. Germany and the United States were the countries with the highest number of filings. In the prospected documents, it was possible to identify that there is a need for the further investigation of the joint use of both techniques. These investigations may lead to the development of processes and devices that can provide economic and environmental gains for the energy industry.

Abstract Objectives To evaluate the accuracy and reliability of dental MRI for static guided implant surgery planning. Materials and methods In this prospective study, a 0.4-mm isotropic, artifact-suppressed, 3T MRI protocol was used for implant planning and surgical guide production in participants in need of dental implants. Two dentists decided on treatment plan. Surgical guides were placed intraorally during a subsequent reference cone beam computed tomography (CBCT) scan. Inter-rater and inter-modality agreement were assessed by Cohen’s kappa. For each participant, dental MRI and CBCT datasets were co-registered to determine three-dimensional and angular deviations between planned and surgically guided implant positions. Results Forty-five implants among 30 study participants were planned and evaluated (17 women, 13 men, mean age 56.9 ± 13.1 years). Inter-rater agreement (mean κ 0.814; range 0.704–0.927) and inter-modality agreement (mean κ 0.879; range 0.782–0.901) were both excellent for the dental MRI-based treatment plans. Mean three-dimensional deviations were 1.1 ± 0.7 (entry point) and 1.3 ± 0.7 mm (apex). Mean angular deviation was 2.4 ± 1.5°. CBCT-based adjustments of MRI plans were necessary for implant position in 29.5% and for implant axis in 6.8% of all implant sites. Changes were larger in the group with shortened dental arches compared with those for tooth gaps. Except for one implant site, all guides were suitable for clinical use. Conclusion This feasibility study indicates that dental MRI is reliable and sufficiently accurate for surgical guide production. Nevertheless, more studies are needed to increase its accuracy before it can be used for implant planning outside clinical trials. Key Points • An excellent reliability for the dental MRI-based treatment plans as well as agreement between dental MRI-based and CBCT-based (reference standard) decisions were noted. • Ideal implant position was not reached in all cases by dental MRI plans. • For all but one implant site surgical guides derived from dental MRI were sufficiently accurate to perform implant placement (mean three-dimensional deviations were 1.1 ± 0.7 (entry point) and 1.3 ± 0.7 mm (apex); mean angular deviation was 2.4 ± 1.5°).

Abstract:

The accuracy of static guided implant surgery (sGIS) using conventional planning workflow has been extensively examined; however, more information is required to justify the application of fully digital planning protocol. The purpose of this study was to investigate the clinical accuracy of sGIS with a fully digital planning workflow. Twenty-one partially edentulous patients were enrolled in this prospective study. Cone-beam computed tomography (CBCT) and intraoral scans were taken and superimposed by matching the dental surface images directly (surface registration protocol) or by matching fiducial markers on a stereolithographic (SLA) radiographic template fabricated from the digital data of the intraoral scan (fiducial marker registration protocol). Virtual implant treatment plans were then determined, and tooth-supported SLA surgical guides were fabricated according to the plans. Twenty-six implant surgeries were performed via the surgical guide by one surgeon. Pre- and post-operative CBCT images were superimposed, and the positional and angular deviations between placed and planned implants were measured with metrology software. A total of 43 fully guided implants were placed, in which 25 implants were planned with the surface registration protocol. Implants planned based on the surface registration protocol had a larger mean angular deviation than the fiducial marker registration protocol. No significant differences were found for any deviations of the examined variables. Within the limits of this study, we concluded that the clinical accuracy of the sGIS planned with a fully digital workflow was consistent with the conventional workflow for partially edentulous patients.

Abstract:

Abstract Background and study aims Colonoscopy can be technically challenging and cause discomfort in patients. The integrated Scope Guide assist is built in to show that with its use outcomes are improved during colonoscopy. We aimed to test the usefulness of the Magnetic Scope Guide Assist (ScopeGuide) with respect to cecal intubation time, and other procedural quality outcomes. Patients and methods We conducted a prospective study of outpatients undergoing elective colonoscopy at the endoscopic units of the University of Alabama at Birmingham (UAB) from March 2016 to July 2016. Patients were randomly assigned in a 1:1 block design to groups that either had standard colonoscopy or Scope-guided colonoscopy. The primary outcome measure was cecal intubation time (CIT). Secondary outcome measures included use of manual pressure, position changes for cecal intubation and sedation requirements. Results Three hundred patients were randomized to either group; standard (n = 150) vs. Scope-guided (n = 150). The mean CIT was not statistically different for the standard and the Scope-guided groups (4.6 vs. 4.3 minutes; P = 0.46). There were also no statistical differences in frequency of manual pressure applied (16.7 % for Scope-guided vs. 19.1 % for standard; P = 0.65) or position changes (11.4 % for scope guided vs. 8.8 % standard; P = 0.56). Sedation requirements showed lesser use of midazolam (3.9 mg vs. 4.7 mg, P = 0.003) in the Scope-guide group, while there was no significant difference in use of fentanyl (fentanyl – 62.1 mg vs. 68.9 mg, P = 0.09 similar between groups, for Scope-guided vs. standard groups, respectively). Adverse events were similar in both groups. Conclusions In patients undergoing routine elective colonoscopy, use of ScopeGuide by experienced colonoscopists did not improve CIT or affect the frequency of ancillary maneuvers. The benefit of this device during training of endoscopists could be considered for further studies.

Abstract:

ObjectivesTo summarise current data on the value of imaging to guide interventional procedures in patients with rheumatic and musculoskeletal disease (RMDs) informing an European Alliance of Associations for Rheumatology taskforce.MethodsA systematic literature review was conducted to retrieve prospective and retrospective studies published in English and comparing different (imaging) techniques, different settings and procedural protocols to guide interventions in patients with RMDs. MEDLINE, EMBASE, the Cochrane Library and Epistemonikos databases were searched through October 2021. Risk of bias (RoB) was assessed using the Cochrane RoB tool for randomised trials V.2 (ROB2), the RoB tool for Non-Randomised Studies of Interventions and the appraisal tool for cross-sectional studies.ResultsSixty-six studies were included (most with moderate/high RoB); 49 were randomised controlled trials, three prospective cohort studies and 14 retrospective studies. Fifty-one studies compared either one imaging technique with another imaging technique, or with palpation-guided interventions. Ultrasound (US) was most frequently studied (49/51), followed by fluoroscopy (10/51). Higher accuracy was found for US or fluoroscopy compared with palpation-guided interventions. Studies comparing different imaging techniques (12/51) did not endorse one specific method. Different settings/equipment for imaging-guided procedures (eg, automatic vs manual syringes) were investigated in three studies, reporting heterogeneous results. Fifteen studies compared different imaging-guided procedures (eg, intra-articular vs periarticular injections).ConclusionHigher accuracy of needle positioning at joints and periarticular structures was seen in most studies when using imaging (especially US) guidance as compared with palpation-guided interventions with the limitation of heterogeneity of data and considerable RoB.

ABSTRACT General objective: To contribute to a better knowledge of Senna obtusifolia (L.) in Burkina Faso. Specific objectives: to identify the endogenous knowledge related to the nomenclature of the plant, to identify the endogenous knowledge related to the use of the plant, to collect the seed of Senna obtusifolia. Methodology and results: The survey and collection allowed noting the presence of Senna obtusifolia (Casse fétide) in the studied area and to collect 132 accessions. The ethnobotanical survey allowed the collection of endogenous knowledge related to the plant. The survey unit was the household. Fourteen ethnic groups were encountered in the 237 households surveyed. Phenomena of synonymy, use of the same name by two or more ethnic groups and unexplained names were observed. The species is used in food as well as in medicine. It is also a source of revenues for the local population. Conclusion and application of results: A lot of endogenous knowledge about the species was collected from the local population. This endogenous knowledge will serve as a guide for the development of the species. The 132 accessions collected will be used for other studies such as agromorphological characterization, physico-chemical characterization and molecular genetic characterization in order to better understand its diversity, conserve it and better valorize the species. The present study will thus allow to establish scientific bases for the conservation, the valorisation and the genetic improvement of the species. Keywords: Senna obtusifolia, endogenous knowledge, ethnobotanical study, Burkina Faso.

Abstract:

Object. The authors describe their initial results obtained using a skull-mounted trajectory guide for intraoperative magnetic resonance (MR) imaging—guided brain biopsy sampling. The device was used in conjunction with a new methodology known as prospective stereotaxis for surgical trajectory alignment. Methods. Between January 1999 and March 2000, 38 patients underwent 40 brain biopsy procedures in which prospective stereotaxis was performed with the trajectory guide in a short-bore 1.5-tesla MR imager. In most cases, orthogonal T2-weighted half-Fourier acquisition single-shot turbo spin—echo (HASTE) images were used to determine the desired trajectory and align the device. The surgical trajectory was defined as a line connecting three points: the target, pivot, and alignment stem points. In all cases, surgical specimens were submitted for frozen section and pathological examination. Postoperative turbofluid-attenuated inversion-recovery and gradient-echo images were obtained to exclude the presence of hemorrhage. Trajectory determination and alignment was simple and efficient, requiring less than 5 minutes. Confirmatory HASTE images were obtained along the biopsy needle as it was being advanced or after reaching the target. All biopsy procedures yielded diagnostic tissue. One patient with a lesion near the motor strip experienced a transient hemiparesis of the hand related to passage of the biopsy needle, and another sustained a fatal postoperative myocardial infarction. No patient suffered a clinically significant or radiologically visible hemorrhage. Conclusions. In combination with prospective stereotaxis, the trajectory guide provided a safe and accurate way to perform brain biopsy procedures.

Abstract:

The aim of this study is to compare the implant placement deviations and evaluate the 1-year post-implant placement bone loss of pilot and fully guided implant placement protocols. In the first method, the pilot drill is used for guide surgery, and the following procedure is a method for performing implant surgery in a non-guided protocol. The second method is to perform fully guided surgery. A total of 74 implants in 20 patients were included. Postoperative CT scans were used to compare the implant placement deviations with the preoperative plan. In addition, bone loss was compared one year after surgery. In shoulder area, the implant deviations from the planned positions for dx(mesio-distal), dy(bucco-lingual), dz(vertical) dimensions, mean deviations with pilot-guided protocol (n = 31) were 0.50 ± 0.42 mm, 0.61 ± 0.55 mm, 0.87 ± 0.71 mm, and 1.33 ± 0.75 mm, respectively. The corresponding deviations for fully guided protocol (n = 41) were 0.50 ± 0.52 mm, 0.29 ± 0.27 mm, 0.56 ± 0.51 mm, and 0.96 ± 0.57 mm. In apical area, the corresponding deviations for pilot-guided protocol were 0.75 ± 0.72 mm, 0.61 ± 0.46 mm, 0.98 ± 0.76 mm, and 1.54 ± 0.87 mm. Deviations for fully guided protocol were 0.91 ± 0.90 mm, 0.44 ± 0.39 mm, 0.54 ± 0.51 mm, and 1.38 ± 0.76 mm, respectively. Angular deviations were 3.33 ± 3.23° with pilot-guided protocol and 3.90 ± 1.85° with fully guided protocol. The average bone loss after 1 year was 0.50 + 0.29 mm and 0.50 ± 0.24 mm, respectively. In the shoulder area, dy(bucco-lingual) of horizontal deviations, vertical deviations, and mean value of the deviations showed a statistically significant difference between fully guided and pilot-guided (p = 0.005, p = 0.033, and p = 0.023, respectively). In the apical area, vertical deviations showed a statistically significant difference. However, the mean value of the deviations did not show a statistically significant difference (p = 0.347). There was no statistically significant difference in angular deviations (p = 0.59).

ABSTRACT Aims The present study was conducted in the fertility unit of a medical college to compare the implantation rate of embryo in ultrasound-guided vs clinical touch method of embryo transfer. Today, approximately 80% of women undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) will reach the embryo transfer stage with good quality embryos. Traditionally, the ‘clinical touch’ method has been used to guide placement of the embryo transfer. The use of ultrasound to guide embryo transfer would allow accurate and atraumatic positioning of the catheter tip near the uterine fundus. Materials and methods A prospective study was conducted at fertility center of Mahatma Gandhi Hospital. A total 100 patients requiring IVF, from a period of July 2011—July 2013 were taken into the study. A total of 50 patients were subjected to USG-guided embryo transfer and 50 patients were subjected to clinical touch embryo transfer. Detailed patient history, clinical examination, relevant investigation and details of procedure were entered in a prestructured proforma. The data were entered and analyzed in Microsoft Office Excel. Results There was a significant improvement in the implantation rates in the USG-guided group (31.9%) as compared to clinical touch group (24.3%). There was also a significant improvement in the pregnancy rates in the USG-guided group (40%) as compared to the clinical touch group (28%). Compared with the traditional clinical touch method, the abdominal ultrasound-guided embryo transfer was found to have a number of advantages.

Abstract:

Background: The aim of the study was to evaluate the safety of fiberoptic bronchoscope guided percutaneous dilatational tracheostomy performed in the intensive care unit.Methods: This was a prospective clinical study done on 30 critically ill patients in Intensive care unit. A puncture was made with 16G cannula at the second or third tracheal interspace which was confirmed by the fiberoptic bronchoscope. This was followed by insertion of guide wire through the cannula followed by insertion of the guiding catheter over the guide wire. The tract was enlarged with white single stage dilator to allow placement of a standard tracheostomy tube. The procedure was continuously monitored with the fiberoptic bronchoscope. Complications were noted during procedure and till patient’s stay in Intensive care unit.Results: The study included 18 (60%) male and 12 (40%) female patients. The mean age was 64.5±8 years. Percutaneous dilatational tracheostomy was done early (<10 days) in 10 (33.3%) patients and late (>10 days) in 20 (66.7%) patients. Fentanyl was used for the procedure in all the patients and among them 8 (26.6%) patients required injection rocuronium. Average procedure duration, from incision to suture for 30 patients was 12.6± 2 minutes. Indication for tracheostomy was weaning failure in 22 (73.3%) patients and airway maintenance in 8 (26.6%) patients. The mean duration patient remained on mechanical ventilation was 12.6 days and mean length of stay in critical care unit before shifting to ward was 7.6 days after tracheostomy. Acute postprocedure complications were transient bleed in four patients (13.3%), two (6.7%) had stomal bleeding, one (3%) had tracheal mucosa laceration and another (3%) had subcutaneous emphysema. No cases of stomal infection, pneumothorax, tracheal laceration, paratracheal insertion, pneumothorax and pneumomediastinum. There was no procedure-related mortality. Conclusion: Fiberoptic bronchoscope guided percutaneous dilatational tracheostomy is safe and the method of choice for elective tracheostomy in the majority of intensive care patientsJournal of Society of Anesthesiologists of Nepal 2015; 2(2): 52-55

Abstract:

This paper presents an exploratory and descriptive study on the use of the prospective research applied to the design management to generate innovation guided by the meaning. Innovation has been used as a key strategy for growth and maintenance of companies in the competitive market. However, in most cases, the development of innovation is either usually based on technological change, or on traditional market research. The first needs strong investment and time and the second relies only on the needs articulated by today's consumers, what limits the innovative results. In this context, as alternative approach, prospective research is considered a strong strategy, as it anticipates future consumer’s needs. Nevertheless, aiming at the designer’s work, there is a lack of information on how to manage it to foster meaning innovation by searching emerging opportunities using prospecting surveys. Therefore, this work aimed at the proposal of requirements to improve management of design in companies, by the use of prospective research to foster innovation guided by meaning. First, the research was conduct by a bibliographical review, with systematic and unsystematic phases followed by their interpretation and analysis that resulted in a preset of guidelines. From them, a Delphi method was conducted with manager’s and designers’ experts, to reinforce our review them. Confronting the previous results, the work proposes a list of requirements for the strategic, tactic and operational levels of design management. They intend to improve the use of prospective research within design management to generate innovation guided by meaning.

Abstract:

Introduction: As elsewhere in the world, Quebec (Canada) is currently facing the COVID-19 pandemic. Approximately 92% of deaths have occurred among people aged over 70, and approximately 100 long-term care (LTC) centers (termed CHSLDs in Quebec) were contaminated. This alarming situation is prompting stakeholders from healthcare networks to investigate the socio-economic repercussions of COVID-19. To the best of our knowledge, there is no valid and reliable tool to measure the costs associated with the management of COVID-19 in CHSLDs. Objectives: This research protocol aims to: i) adapt and validate for use in CHSLDs a combined guide, Cout-COVID19-SLD, developed from 2 guides used in acute care; ii) pilot the Cout-COVID19-SLD guide in CHSLDs and test its feasibility and afterwards resolve any barriers to its administration, and to conduct a partial estimate of costs brought about by COVID-19. Methods: A two-part prospective study will be conducted. Phase 1 will use a Delphi approach with 14 to 17 experts to validate the content of the Cout-COVID19-SLD guide. Phase 2 will pilot test the guide in a cross-sectional study in two CHSLDs. Discussion and conclusion: This study will provide a validated guide for the systematic measurement of costs associated with the management of COVID-19 (costs of preventive measures and costs of illness) in CHSLDs. Finally, this guide will serve as a valid and reliable instrument with which to better plan future research surrounding the socio-economic impacts of COVID-19 in CHSLDs.

Abstract:

Purpose The purpose of this study was to compare, in terms of blood loss and implant alignment, a new generation of smart extramedullary (EM) cutting guides with the conventional intramedullary (IM) guide for total knee arthroplasty (TKA). The hypothesis was that the EM system would result in less blood loss and fewer days of hospitalization, while ensuring equal or higher accuracy in the alignment of the femoral implant. Methods Thirty-six patients were enrolled for the present study: 18 patients underwent TKA using the EM guide and for the other 18 patients the IM guide was used. Preoperative and postoperative X-rays were acquired. The preoperative and postoperative hemoglobin values were compared. Lastly, length of hospital stay was recorded. Results The hemoglobin difference was significantly lower in the EM group. The alignment of the prosthetic femoral implant in the two groups was comparable but all patients in the EM cohort had a final alignment within 3 degrees of range on the frontal view, while 22% of the patients in the IM cohort had a final alignment exceeding 3 degrees of range. The mean hospitalization duration showed no significant difference between groups, though EM group showed 1.6 days less compared with IM group. Conclusions The inertial-based EM guide system could be useful for decreasing blood loss compared with conventional guide. This device tended to have better results even in terms of accuracy, but this difference was not significant. Level of Evidence This is a level II, prospective cohort study.

Abstract:

Background: Initiation of a long-term improvement of cardiac risk factors is one of the major aims of a cardiac rehabilitation/secondary prevention programme. Methods and participants: The Health Guide collected data in terms of cardiac risk factors: blood pressure, resting pulse, total cholesterol, LDL cholesterol, body weight, physical activity and number of cigarettes at admission and discharge after a stationary rehabilitation programme and every 3 months. After 12 months the Health Guides were returned. In the prospective study 2664 patients (71.8% men, age: MV = 62.94 years, SD = 9.96; 28% women, MV = 67.59 years, SD = 9.53) with coronary heart disease (CHD) were included. Results: All cardiac risk factors documented by the Health Guide improved during the cardiac rehabilitation programme. After one year, risk factors were significantly lower than at admission, apart from total cholesterol. The individual goal in terms of body weight and LDL cholesterol was partially achieved after the rehabilitation programme and maintained after one year. In the investigation years, 2004–2007, the cholesterol and blood pressure were significantly lower than in the years 2000–2003. Conclusion: The use of a Health Guide resulted in an improved long-term effect of a cardiac rehabilitation/secondary prevention programme. It is a simple and cheap intervention and can help in the guidance of the patients.

Abstract:

Supervised, center-based, daily physiotherapy presents limitations: transport, need for an accompanying person, or risk of infection. Home-based rehabilitation protocols (HBRP) can be effective alternatives. We use a HBRP for the non-surgically treated proximal humeral fractures (PHF) in older patients. Objectives To assess patient satisfaction and preferences of using a booklet, videos, or an app to guide physiotherapy. Patients and methods Prospective, single-center observational study of patients ≥55 years old who sustained a non-surgically treated PHF. The HBRP consisted of immediate mobilization, followed by 5 physiotherapist-guided, weekly sessions of rehabilitation and standard physiotherapy after 3 months, if needed. A booklet with images, videos, or a smartphone application were offered to guide the patients. Results Mean degree of satisfaction (1-5) was 4.66 ± .9: 84 patients (82.4%) were very satisfied, 11 patients (10.8%) were satisfied, and 5 patients (4.9%) were not satisfied at all. Mean Oxford Shoulder Score achieved was 40.5 ± 6.6. 59.8% patients preferred the booklet and 29.4% the videos. Exercise compliance was considered very high in 87.3% of patients, while 4% hardly never followed the HBRP. Only 17.7% patients needed center-based physiotherapy after the HBRP. Discussion Reasons for satisfaction were good final functional outcome, no need for transportation, being away from hospital, immediate rehabilitation availability and being capable of maintaining independence. Adherence is a major concern. Videos are more didactic explaining the exercises. Conclusion If standard physiotherapy is not available, the HBRP can be a valid treatment option for PHF management in older patients, with a high degree of patient satisfaction. Older patients preferred the booklet to guide physiotherapy.

Abstract:

Object. The goal of this study was to compare the freehand technique of catheter placement using external landmarks with the technique of using the Ghajar Guide for this procedure. The placement of a ventricular catheter can be a lifesaving procedure, and it is commonly performed by all neurosurgeons. Various methods have been described to cannulate the ventricular system, including the modified Friedman tunnel technique in which a soft polymeric tube is inserted through a burr hole. Paramore, et al., have noted that two thirds of noninfectious complications have been related to incorrect positioning of the catheter.Methods. Forty-nine consecutive patients were randomized between either freehand or Ghajar Guide—assisted catheter placement. The target was the foramen of Monro, and the course was through the anterior horn of the lateral ventricle approximately 10 cm above the nasion, 3 cm from the midline, to a depth of 5.5 cm from the inner table of the skull. In all cases, the number of passes was recorded for successful cannulation, and pre- and postplacement computerized tomography scans were obtained. Calculations were performed to determine the bicaudate index and the distance from the catheter tip to the target point.Conclusions. Successful cannulation was achieved using either technique; however, the catheters placed using the Ghajar Guide were closer to the target.

Abstract:

Objective. To investigate if 3D printed guides and preoperative planning can accurately control femoral stem anteversion. Methods. A prospective comparative study was carried out from 2018 to 2020, including 53 patients who underwent hip arthroplasty for femoral neck fracture. The target rotation center of the femoral head is determined by three-dimensional planning. In group A, planning was made by 2D templates. In group B, preoperative 3D planning and 3D printed osteotomy/positioning guides were performed. After the operation, 3D model registration was performed to calculate the accuracy of anteversion restoration. Results. We screened 60 patients and randomized a total of 53 to 2 parallel study arms: 30 patients to the group A (traditional operation) and 23 patients to the group B (3D preoperative planning and 3D printed guide). There were no significant differences in demographic or perioperative data between study groups. The restoration accuracy of group A was 5.42 ° ± 3.65 ° and of group B was 2.32 ° ± 1.89 ° . The number and rate of abnormal cases was 15 (50%) and 2 (8.7%), respectively. Significant statistical differences were found in angle change, restoration accuracy, and number of abnormal cases. Conclusion. Three-dimensional preoperative planning and 3D printed guides can improve the accuracy of the restoration of femoral anteversion during hip arthroplasty.

Abstract:

Abstract. Knowledge of free ligand conformational preferences (energy minima) and conformational dynamics (rotational energy barriers) of small molecules in solution can guide drug design hypotheses and help rank ideas to bias syntheses towards more active compounds. Visualization of conformational exchange dynamics around torsion angles, by replica exchange with solute tempering molecular dynamics (REST-MD), gives results in agreement with high-resolution 1H nuclear magnetic resonance (NMR) spectra and complements free ligand conformational analyses. Rotational energy barriers around individual bonds are comparable between calculated and experimental values, making the in-silico method relevant to ranking prospective design ideas in drug discovery programs, particularly across a series of analogs. Prioritizing design ideas, based on calculations and analysis of measurements across a series, efficiently guides rational discovery towards the “right molecules” for effective medicines.

Animals: Forty-one client-owned female cats scheduled for ovariectomy were enrolled in the study and randomly assigned to one of the treatment groups. Methods: Both treatment and control groups received general anesthesia and a bilateral rectus abdominis sheath block (RSB) under ultrasound guidance. The block was performed with 0.05 mL kg -1 of 2% lidocaine and 0.15 mL kg -1 of 0.5% bupivacaine mixed together in each rectus abdominis sheath (group A) or the equivalent volume of saline (group B). Intraoperative pain assessment was based on changes in physiological parameters compared to the baseline values and rescue analgesic requirement. Postoperative pain assessment was performed using the 4A-Vet pain scale and the need for rescue analgesics at 1, 2, 4 and 6 hours after extubation. The sedation was evaluated and graded at the same times. The owners were asked to fill a questionnaire at three time points: the night the cat was back home, the next morning and ten days after the surgery. Results: There were two significant differences between group A and B: less isoflurane was needed in group A during the suturing phases (p = 0.04 during peritoneal muscular sutures and 0.02 during skin suture) and cats from group A were less sedated 6 hours after extubation (p = 0.03338). Conclusions and clinical relevance: In summary, our study concludes that ultrasound-guided RSB decreases the amount of isoflurane used during surgical closing time and the sedation score 6 hours after extubation. The block was easily and successfully performed. Further studies are needed to adjust the local anesthetic volume and prove its long-term efficacy in cats.

Abstract:

Abstract Purpose Ultrasound-guided biopsy (US biopsy) with 10–12 cores has a suboptimal sensitivity for clinically significant prostate cancer (sigPCa). If US biopsy is negative, magnetic resonance imaging (MRI)–guided biopsy is recommended, despite a low specificity for lesions with score 3–5 on Prostate Imaging Reporting and Data System (PIRADS). Screening and biopsy guidance using an imaging modality with high accuracy could reduce the number of unnecessary biopsies, reducing side effects. The aim of this study was to assess the performance of positron emission tomography/MRI with 68Ga-labeled prostate-specific membrane antigen (PSMA-PET/MRI) to detect and localize primary sigPCa (ISUP grade group 3 and/or cancer core length ≥ 6 mm) and guide biopsy. Methods Prospective, open-label, single-center, non-randomized, diagnostic accuracy study including patients with suspected PCa by elevation of prostate-specific antigen (PSA) level and a suspicious lesion (PIRADS ≥3) on multiparametric MRI (mpMRI). Forty-two patients underwent PSMA-PET/MRI followed by both PSMA-PET/MRI-guided and section-based saturation template biopsy between May 2017 and February 2019. Primary outcome was the accuracy of PSMA-PET/MRI for biopsy guidance using section-based saturation template biopsy as the reference standard. Results SigPCa was found in 62% of the patients. Patient-based sensitivity, specificity, negative and positive predictive value, and accuracy for sigPCa were 96%, 81%, 93%, 89%, and 90%, respectively. One patient had PSMA-negative sigPCa. Eight of nine false-positive lesions corresponded to cancer on prostatectomy and one in six false-negative lesions was negative on prostatectomy. Conclusion PSMA-PET/MRI has a high accuracy for detecting sigPCa and is a promising tool to select patients with suspicion of PCa for biopsy. Trial registration This trial was retrospectively registered under the name “Positron Emission Tomography/Magnetic Resonance Imaging (PET/MRI) Guided Biopsy in Men with Elevated PSA” (NCT03187990) on 06/15/2017 (https://clinicaltrials.gov/ct2/show/NCT03187990).

Abstract:

Purpose: The purpose of this study was to determine the clinical utility of an algorithm-based decision tool designed to assess risk associated with opioid use in the primary care setting. Methods: A prospective, longitudinal study was conducted to assess the utility of precision medicine testing in 1822 patients across 18 family medicine/primary care clinics in the United States. Using the profile, patients were categorized into low, moderate, and high risk for opioid use. Physicians who ordered testing were asked to complete patient evaluations and document their actions, decisions, and perceptions regarding the utility of the precision medicine tests. Results: Approximately 47% of primary care physicians surveyed used the profile to guide clinical decision-making. These physicians rated the benefit of the profile on patient care an average of 3.6 on a 5-point scale (1 indicating no benefit and 5 indicating significant benefit). Eighty-eight percent of all clinicians surveyed felt the test exhibited some benefit to their patient care. The most frequent utilization for the profile was to guide a change in opioid prescribed. Physicians reported greater benefit of profile utilization for minority patients. Patients whose treatment was guided by the profile had pain levels that were reduced, on average, 2.7 levels on the numeric rating scale. Conclusions: The profile provided primary care physicians with a useful tool to stratify the risk of opioid use disorder and was rated as beneficial for decision-making and patient improvement by the majority of physicians surveyed. Physicians reported the profile resulted in greater clinical improvement for minorities, highlighting the objective use of this profile to guide judicial use of opioids in high-risk patients. Significantly, when physicians used the profile to guide treatment decisions, patient-reported pain was greatly reduced.
