TIPiCO is an annual expert meeting and workshop on infectious diseases and vaccination. The edition of 2020 changed its name and format to aTIPiCO, the first series and podcasts on infectious diseases and vaccines. A total of 13 prestigious experts from different countries participated in this edition launched on the 26 November 2020. The state of the art of coronavirus disease-2019 (COVID-19) and the responsible pathogen, the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), and the options to tackle the pandemic situation were discussed in light of the knowledge in November 2020. Despite COVID-19, the status of other infectious diseases, including influenza infections, respiratory syncytial virus disease, human papillomavirus infection, measles, pertussis, tuberculosis, meningococcal disease, and pneumococcal disease, were also addressed. The essential lessons that can be learned from these diseases and their vaccines to use in the COVID-19 pandemic were also commented with the experts.Purpose In 1979 Vern Seefeldt postulated that individuals that did not achieve a given level of proficiency in the fundamental movement skills (FMS) would be limited in performance on new and more complex skills during development. This hypothesis, the proficiency barrier, inspired research in motor development but, to the best of our knowledge, was never empirically tested. The present article tested three potential mathematical functions (linear, sigmoidal and piecewise) describing the proficiency barrier relating FMS with a transitional movement skill (TMS, a more complex movement skill). Methods 87 children aged 7 to 10 years were tested on six skills of the TGMD-2 test battery (running, hopping, leaping, kicking, catching and stationary bouncing) and dribbling (a combination of running and stationary bouncing). Results The results showed evidence for the proficiency barrier based on a specific sigmoidal relation. We also identified critical movement aspects from FMS that seem to induce this relation. Conclusion There is some evidence supporting Seefeldt's Proficiency Barrier.
Objective Structured Clinical Examinations (OSCE) are used to assess clinical skills. We investigated how exit OSCEs changed in Australian medical schools in response to the COVID-19 pandemic.
The lead ACCLAiM assessment academic from 12 eligible Australian medical school members of the Australian Collaboration for Clinical Assessment in Medicine (ACCLAiM) received a 45-item semi-structured online questionnaire.
All schools (12/12) responded. Exit OSCEs were not used by one school in 2019, and 3/11 schools in 2020. Of eight remaining schools, four reduced station numbers and testing time. The minimum OSCE testing time decreased from 64 min in 2019 to 54 min in 2020. Other modifications included a completely online 'e-OSCE' (
= 1); hybrid delivery (
= 4); stations using videos of patient encounters (
= 3), telephone calls (
= 2), skill completion without face-to-face patient encounters (
= 3). The proportion of stations involving physical examination reduced from 33% to 17%. Fewer examiners were required, and university faculty staff formed a higher proportion of examiners.
All schools changed their OSCEs in 2020 in response to COVID-19. Modifications varied from reducing station numbers and changing delivery methods to removing OSCE and complete assessment re-structuring. Several innovative methods of OSCE delivery were implemented to preserve OSCE validity and reliability whilst balancing feasibility.

Little research has explored the process of disclosure decision-making from antecedents to outcomes. This paper presents a model of decision-making about disclosure of a mental health condition to the immediate supervisor in the workplace shortly after starting a new job.
A qualitative descriptive design was employed to explore participants' experiences of the disclosure decision-making process, the disclosure event itself (if applicable), and their perceptions of the impact of the decision on personal, interpersonal, and organizational outcomes. The transcripts were coded and analyzed using directed content analysis.
Twenty-eight participants were purposively selected to represent different disclosure decisions, sex, diagnoses, and maintenance of employment. Analysis identified goals and conditions/context were important antecedents for the disclosure decision. All participants discussed concerns about prejudice and discrimination if they disclosed, and, for those who chose to disclose, high stress andtional norms into account.Background Although surgical stabilization for rib fractures (SSRF) has been adopted widely over the past decade, little information is available regarding the prevalence and outcomes of post-operative surgical site infection (SSI). We hypothesized that SSI after SSRF is uncommon but morbid. Patients and Methods Patients undergoing SSRF at a level 1 trauma center from 2010-2020 were reviewed. The primary outcome was the prevalence of SSI, documented by clinical examination, radiography, systemic markers of infection, and microbiology. Results Of 228 patients undergoing SSRF, 167 (73.2%) were male, the median age was 53 years (P25-P75; 41-63 years), injury severity score (ISS) was 19 (P25-P75, 13-26), with a median of eight fractured ribs (P25-P75, 6-11). All stabilization plates were titanium. SSRF was typically performed on post-injury day one (P25-P75, 0-2 days) after trauma. All patients received antibiotic agents within 30 minutes of incision, and a median of four ribs (P25-P75, 3-6) were repaired. Four (1.8%) patients developed an SSI and all underwent implant removal. Two patients required implant removal within 30 days (on post-operative day seven and 17) and two for chronic infection at seven and 17 months after SSRF. The causative organism was methicillin-sensitive Staphylococcus aureus (MSSA) bacteria in all patients. After implant removal, three patients received intravenous and oral antibiotic agents, ranging from two to six weeks, without recurrent infection. No patient required additional SSRF. Conclusions Surgical site infection after SSRF is rare but morbid and can become symptomatic within one week to 17 months. Implant removal results in complete recovery.Background Institutional programs such as antibiotic stewardship (ABS) programs offer possibilities to monitor and modify antibiotic usage with the aim of reducing antibiotic resistance. In orthopedic units that treat peri-prosthetic joint infections (PJIs), ABS programs are still rare, however, there is extensive use of high-risk antibiotic agents and an increased risk for the occurrence of Clostridium difficile infections (CDIs). Patients and Methods An ABS program was implemented at the Department of Orthopedic Surgery at a university hospital. ABT-199 solubility dmso Quarterly antibiotic consumption was measured in defined daily doses (DDDs) per 100 patient-days (PDs) at 10 quarters before the intervention and seven quarters after the intervention. The effect of the new antibiotic policy on drug use rates was evaluated using an interrupted time-series analysis. Estimated changes over time in the incidence of CDIs (cases per 1,000 PDs) were analyzed. Results A remarkable percentual reduction in second-generation cephalosporin use of 83% (p less then 0.001; pre-intervention level, 81.486 DDDs/100 patient-days; post-intervention level, 13.751 DDDs/100 PDs) and clindamycin administration of 78% (p less then 0.001; pre-intervention level, 18.982 DDDs/100 PDs; post-intervention level, 4.216 DDDs/100 PDs) was observed after implementation of ABS interventions. Total antibiotic use declined by 25% (p less then 0.001; pre-intervention level, 129.078 DDDs/100 PDs; post-intervention level, 96.826 DDDs/100 PDs). Conclusions This research assessed the positive impact of an intensified ABS program at an orthopedic department specializing in PJIs. Antibiotic stewardship program interventions encourage the reduction of total antibiotic usage and especially high-risk antibiotic agents, associated with the development of antimicrobial resistance.Background Recurrent cellulitis has high impact on physical, psychological, and social aspects for lymphedema patients. We speculated that identification of characteristics of skin and subcutaneous adipose tissue with cellulitis history can help considering new approach for prevention of recurrent cellulitis in lymphedema patients. Therefore, in this study, we aimed to noninvasively identify the ultrasonographic features of skin and subcutaneous tissue of lymphedema in patients with a cellulitis history. Method and Results This was a cross-sectional study, and all data were collected from patients' medical records. We assessed ultrasonographic images of the lower extremity of patients with lymphedema that were obtained in a lymphedema clinic. The ultrasonographic images were analyzed on the basis of the following five features dermal hypoechogenicity, unclear dermal border, unclear superficial fascia, increased subcutaneous echogenicity, and subcutaneous cobblestone appearance. Fifty-two ultrasonographic images from 19 female patients with lower extremity lymphedema, including 8 with and 11 without a cellulitis history, were analyzed. The proportion of dermal hypoechogenicity on the upper leg was significantly higher in the patients with than in those without a cellulitis history (75.0% vs. 9.1%, p = 0.006). Conclusion Cellulitis history in lymphedema patients appears to be associated with dermal hypoechogenicity, particularly in the proximal lower extremity. This finding suggests that it may be the initial step to consider new approach for prevention of recurrent cellulitis in lymphedema patients.The analytical value of peaks arising by a proximity effect in the electron ionization mass spectra of benzanilides has been established by examining the spectra of numerous examples of general structure XC6H4NHCOC6H4Y. Significant [M-X]+ signals are observed only when X = Cl, Br, I or CH3O in the 2-position. The presence of strong [M-X]+ signals, but negligibly weak [M-Y]+ peaks, even when the C-Y bond would be expected to break more readily than the C-X bond, indicates that these diagnostically useful signals do not arise by simple cleavage. Similarly, the presence of an appreciable [M-Cl]+ signal, but no [M-Br]+ signal, in the spectra of representative examples of 4-Br-2ClC6H3NHCOC6H4Y, reveals that loss of a substituent from the 2-position occurs much more rapidly than fission of a weaker bond to a substituent in the 4-position. These trends are interpreted in terms of cyclization of the ionized 2-substituted benzanilide, followed by elimination of the substituent originally in the 2-position, to form a protonated 2-arylbenzoxazole.Developing engaging activities that build skills for understanding and appreciating research is important for undergraduate and postgraduate science students. Comparing and contrasting opposing research studies does this, and more it also appropriately for these cohorts challenges higher-level cognitive processing. Here, we present and discuss one such scenario, that of calcineurin in the heart and its response to exercise training. This scenario is further accentuated by the existence of only 2 studies. The background is that regular aerobic endurance exercise training stimulates the heart to physiologically adapt to chronically increase its ability to produce a greater cardiac output to meet the increased demand for oxygenated blood in working muscles, and this happens by 2 main mechanisms 1) increased cardiac contractile function and 2) physiologic hypertrophy. The major underlying mechanisms have been delineated over the last decades, but one aspect has not been resolved the potential role of calcineurin in modulating physiologic hypertrophy.
