IntroductionSerological detection of SARS-CoV-2-specific immunoglobulins G (IgG) and M (IgM) antibodies is becoming increasingly important in the management of the COVID-19 pandemic.MethodsWe report the first results of COVID-19 serological testing in Bosnia and Herzegovina on 2841 samples collected and analysed in 2 medical institutions in Sarajevo. Antibody detection was performed using commercially available kits.ResultsIn the first cohort, 43 IgM-positive/IgG-negative and 16 IgM-positive/IgG-positive individuals were detected, corresponding to 3.41% of participants having developed antibodies. In the second cohort, 4.28% participants were found to be IgM-negative/IgG-positive.ConclusionsOur results suggest the need for population-wide serological surveying in Bosnia and Herzegovina. 相似文献

Introduction
Patients on warfarin with sub-optimal time-in-therapeutic-range (TTR) are more likely to have adverse events. Target-specific oral anticoagulants (TSOACs) are approved and can be used as an alternative to warfarin for a number of indications. Further, the efficacy and safety profiles of the TSOACs compared to warfarin are more favourable when the TTR is ≤ 65% for certain indications.Objective
We aimed to determine simple, sensitive and specific diagnostic tools to identify TTR ≤ 65% during the initial three months of warfarin therapy.Methods
A cross-sectional study including patients newly initiated on warfarin without any interruption for three months was conducted. TTR was calculated using the Rosendaal method. Patients were stratified by TTR (≤ 65% or > 65%). Number of INR measurements, dose changes and INR measurements of ≤ 1.7 or ≥ 4.0 were evaluated as potential diagnostic tools to identify TTR ≤ 65%.Results
670 patients were included. The most common indication for anticoagulation was venous thromboembolism. The mean TTR in the first three months was 68 ± 21% (Range: 10 to 100%). Three or more dose changes identified TTR ≤ 65% and demonstrated a sensitivity and specificity of 90% (95%CI 86 to 93%) and 56% (95%CI 51 to 61%), respectively. Three or more INR measurements of ≤ 1.7 during the initial three months of anticoagulation showed a sensitivity and specificity of 37% (95%CI 32 to 43%) and 98% (95%CI 96 to 99%), respectively.Conclusion
Three or more dose changes and three or more INR measurements of ≤ 1.7 could identify patients with a TTR ≤ 65% in the first three months of warfarin therapy. 相似文献28.

Introduction: One important reason why functional electrical stimulation (FES) has not gained widespread clinical use is the limitation imposed by rapid muscle fatigue due to non‐physiological activation of the stimulated muscles. We aimed to show that asynchronous low‐pulse‐rate (LPR) electrical stimulation applied by multipad surface electrodes greatly postpones the occurrence of muscle fatigue compared with conventional stimulation (high pulse rate, HPR). Methods: We compared the produced force vs. time of the forearm muscles responsible for finger flexion in 2 stimulation protocols, LPR (fL = 10 Hz ) and HPR (fH = 40 Hz ). Results: Surface‐distributed low‐frequency asynchronous stimulation (sDLFAS) doubles the time interval before the onset of fatigue (104 ± 80%) compared with conventional synchronous stimulation. Conclusions: Combining the performance of multipad electrodes (increased selectivity and facilitated positioning) with sDLFAS (decreased fatigue) can improve many FES applications in both the lower and upper extremities.

Objective. To investigate capstone experiences in pharmacy education with the broad aim of better understanding how they are designed, used, and sustained.Methods. Capstones were defined as culminating experiences that required Doctor of Pharmacy (PharmD) students to apply their knowledge and skills and demonstrate their ability to integrate, extend, and apply multiple components of their academic experience. This study was conducted in two phases. Phase one was a mapping review, which provided insight into the design of pharmacy capstone experiences, including the purpose they served and their associated outcomes. Phase two consisted of conducting follow-up interviews to explore the current status and sustainability of those capstone experiences. Qualitative methods with multiple coders were used to analyze the data.Results. Five distinct purposes for capstone experiences were identified: preparation for advanced pharmacy practice experiences (APPEs), pharmacotherapy education, research, reflection on pharmacy school experiences, and immersive learning through an external organization. Wide variability was found in the design, purpose, and outcomes of capstone experiences. Study authors described the capstone experiences at their institution in terms of the viability, feasibility, desirability, and challenges faced.Conclusion. Capstones can play an important role in assessing student progress and practice readiness in pharmacy education. The findings of this study can be used to help pharmacy schools design capstone experiences that are effective and sustainable. 相似文献
