We measured these perforators with the tablet navigation device. The mean difference was 5.4 mm (minimum, 0 mm; maximum, 20 mm). The perforator flaps were elevated safely. The perforator flaps could be elevated safely using our device, as the mean difference was only 10 mm, which is acceptable for navigating perforator flap operations. learn more Pig backs are triangular in shape; therefore, we were unable to place markers on the contralateral side. Thus, for clinical applications of the device, we should determine the ideal marker locations.
Free flap surgeries are useful procedures for lower-extremity reconstruction. Recipient vein selection for anastomosis is important to avoid venous congestion and thrombosis. Although deep or superficial venous system can be used as a recipient vein site, there is a lack of consensus on which system would be superior to avoid postoperative complications. This systematic review and meta-analysis aimed to assess the differences in outcomes between deep and superficial vein anastomosis for lower-extremity free flap reconstruction.
The PubMed, Scopus, Web of Science, and Cochrane Library medical databases were systematically searched from inception to April 2022, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. A comparative meta-analysis was conducted on studies of deep and superficial venous system anastomosis outcomes, comprising vascular thrombosis, reoperation, complete flap necrosis, and any flap necrosis. The fixed-effects meta-analysis model was used when low heterogeneity (I
< 50%) was present.
Six studies with 789 flaps were included in the analysis and qualitative and quantitative syntheses. The rate of vascular thrombosis (8.2% vs. 15.1%; p=.005) was significantly lower for flaps involving deep vein anastomosis than for those involving superficial vein anastomosis. The rate of reoperation after deep vein anastomosis was lower than that after superficial vein anastomosis, with no statistically significant difference (9.0% vs. 14.7%; p=.06). There were no significant differences in the rates of complete (2.5% vs. 2.0%; p=.90) or any flap necrosis (7.0% vs. 9.8%; p=.20).
Deep vein anastomosis might be recommended for avoiding vascular thrombosis.

Oral cladribine is a highly effective pulsed selective immune reconstitution therapy licensed for relapsing multiple sclerosis (RMS) since 2017. A full treatment course comprises two treatment cycles given 1 year apart, followed by two treatment-free years. The management of cladribine-treated patients beyond year 4 needs to be addressed as patients have now passed the initial 4years since European Medical Agency approval.
A panel of neurologists and a neuroradiologist experienced in MS treatment/monitoring evaluated clinical trial data and real-world evidence and proposed recommendations for the management of cladribine-treated patients beyond year 4.
Continuous monitoring of disease activity during the treatment-free period is important. Subsequent management depends on the presence or absence of inflammatory disease activity, determined in the absence of consistent guidelines via practice-driven neurological decision criteria. Persisting or newly occurring inflammatory disease activity is an indicatiring disease course, treatment history, and safety aspects. In the absence of disease activity, either retreatment can be offered, or the treatment-free period can be extended under structured monitoring.
There is a clinical need for a quantitative test to objectively diagnose negative dysphotopsia, especially because the diagnosis is generally assessed using patients' subjective descriptions. In the search of a clinical test to objectify the shadow experienced in negative dysphotopsia, this study excludes static perimetry as suitable evaluation method.
This study aimed to evaluate the value of static perimetry in the objective assessment and follow-up of negative dysphotopsia.
Peripheral 60-4 full-threshold visual field tests were performed in 27 patients with negative dysphotopsia and 33 pseudophakic controls. In addition, 11 patients with negative dysphotopsia repeated the test after an intraocular lens exchange. Both the total peripheral visual field and the averaged peripheral visual field from 50 to 60° eccentricity were compared between patients and controls, and pre-operatively and post-operatively in patients who had an intraocular lens exchange.
The peripheral visual fields from 30 to 60° didhotopsia.
Full-threshold static perimetry with a Goldmann size III stimulus up to 60° eccentricity does not show significant differences between patients with negative dysphotopsia and pseudophakic controls or between measurements before and after intraocular lens exchange. Therefore, this type of static perimetry cannot be used as a quantitative objective test for diagnosis or follow-up of patients with negative dysphotopsia.High-quality, well-annotated, healthy tissue specimens are crucial to the success of basic and translational research, but often difficult to procure. Postmortem (PM) tissue collections provide the opportunity to collect these healthy biospecimens. PM procurement programs led by biobanks can further contribute by providing researchers with rare biospecimens collected with short postmortem intervals (PMI) in controlled environments. To support biomedical and translational research, the Cornell Veterinary Biobank (CVB), an ISO 20387 accredited core resource at the Cornell University College of Veterinary Medicine, has performed PM tissue collections from research and privately owned animals since 2013. The CVB PM collection team, consisting of a board-certified veterinary pathologist, a licensed veterinary technician collection specialist, and a data capture specialist, performs rapid tissue collections during controlled warm necropsies, with an accepted PMI of ≤2 hours and a target PMI of ≤1 hour. A retrospective analysis of PM collections between 2013 and 2020 was completed, consisting of 4077 aliquots of 1582 biospecimens from 69 donors (48 canine, 16 feline, and 5 equine). An average of 22.93 biospecimens per donor were collected (range 1-49). The average PMI for standard collections was 43.48 ± 2.30 minutes, starting on average 20.81 ± 1.61 minutes after time of death. Thus far, the CVB has a favorable utilization rate, with 414 aliquots (10.15%) from 350 specimens (20.12%) and 45 animals (65.22%) distributed to researchers. The success of the CVB PM tissue biobanking program, collecting high-quality biospecimens with short PMIs, was due to support from veterinary pathologists, the competence of CVB personnel, and the continuous evolution of methods within a quality management system. Improvement of PM tissue collection programs in biobanks, with standardized practices for all processes and specialized personnel, can enhance the quality and increase utilization of its biospecimens and associated data.Phenomenon Compassion, and related constructs such as empathy, are core values in healthcare, with known benefits for both patients and staff. Yet research on the factors that affect compassion and compassion-related constructs remains scattered. This review systematizes and synthesizes studies investigating the predictors of compassion and related constructs among medical students, allowing for a better understanding of the factors that both positively and negatively contribute to the development of compassionate future physicians. Approach A systematic review of 12 databases for studies from database inception up until April 2020 was conducted. Non-peer-reviewed literature and studies in which >50% of the sample were non-medical students were excluded. Intervention studies were also out of the scope of this review. We assessed risk of bias and confidence in the findings using standardized tools. Data were categorized within the Transactional Model of Physician Compassion, a framework in which compassion is sion is predicted by a wide range of factors relating to the student, their training environment, their patients, and the clinical situation. However, existing research has largely focused on student factors (e.g., sociodemographic and dispositional traits), many of which are not amenable to intervention. Skills such as perspective taking, reflection, and mindfulness are associated with higher compassion and may present opportunities for intervention. There is also strong evidence that environmental factors shape students' compassion. Researchers and educators should continue to explore the impact of patient and clinical factors on students' compassion. Studies remain at high risk of bias.Objectives. Workplace inspection supports improving the working environment. Changes in workplaces following inspections are construed as the inspection's outcome. This study aimed to develop a tool for inspection performance assessment (TIPA) based on identified inspection prerequisites and evaluate the tool's appropriateness for performance assessment. Methods. Occupational safety and health experts ranked the prerequisites for effective inspection performance, based on their experiences and perception of importance of the prerequisites. The outcome formed the basis for weighting and assignment of values to the prerequisite subgoals. An assessment tool interface, with which inspectors can assess their workplace inspection performance was designed. Inspectors from different national authorities provided feedback on the tool's appropriateness for measuring inspection performance. Results. Results showed much agreement between the inspectors. A five-level performance consideration based on inspection performance index attained was implemented. High average ratings for the test criteria were obtained, with high inter-rater consistency, and reliability. Conclusion. TIPA provides a systematic inspection performance quantification supporting inspectors' self-actualization, improving performance. Furthermore, the tool's generality allows for use irrespective of the inspection area without affecting inspection areas' specificity adjustments. In addition, the ease of use adds to its utility, with agreement on the tool's appropriateness for inspection performance assessment.Background We investigated the effect of the Whole of Systems Trial of Prevention Strategies for Childhood Obesity (WHO STOPS) intervention on children's objectively measured physical activity and sedentary time (ST). Methods We conducted a cluster randomized controlled trial with children in grades 4 (∼9-10 years old) and grade 6 (∼11-12 years old) from 10 communities in the Great South Coast region of Victoria, Australia. Communities were randomly allocated (11) to receive the WHO STOPS intervention in 2015. WHO STOPS was a whole of community systems-based approach to preventing childhood obesity. Outcome data were collected using a repeat cross-sectional design in 2015, 2017, and 2019. Children were asked to wear a hip-mounted accelerometer for 7 days. Age-specific Axis 1 activity counts were converted into duration (minutes/day) spent engaged in moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), and ST. Linear mixed regression models were fitted to estimate the effects of the intervention on the three activity outcomes across the study period.
