Upper third tears of the subscapularis tendon can be repaired successfully with a single anchor according to previous literature. The aim of the present study was to compare three single anchor repair techniques regarding fixation strength, footprint coverage and contact pressure in a biomechanical test set-up on human cadaveric shoulders.

Eighteen human cadaveric shoulders were randomized in three groups with respect to the repair technique; group 1 knotted lasso-loop mattress, group 2 knotted mattress and group 3 knotless tape repair. Upper third tears of the subscapularis tendon (Lafosse type 2) were created and repairs were performed with additional contact pressure and area measurement using a pressure mapping system. Cyclic testing was performed by loading the subscapularis from 10 to 100N for 300 cycles. A position-controlled ramp protocol up to 30 and 50N was used to allow for pressure measurements. Finally, specimens were loaded to failure and failure modes were recorded.

The three groups were pper third subscapularis tears were able to provide sufficient biomechanical stability. Knotted lasso-loop mattress and knotless tape repair were superior regarding pressurized footprint coverage compared to a knotted horizontal mattress technique and are, therefore, preferable techniques for upper subscapularis repair.

Valgus knees have inferior outcomes compared to varus knees. There is little data regarding soft-tissue balance in flexion which may influence outcome in valgus knees undergoing TKA. The purpose of this study was to evaluate whether there is imbalance between medial and lateral flexion gaps in valgus deformity. A secondary aim was to compare soft-tissue balance in knees with valgus deformity less than 10° with those exceeding 10°. The null hypothesis was that there was no soft-tissue imbalance in 90° of flexion irrespective of magnitude of deformity.

64 valgus knees (52 female and 12 male) with deformity from 0.5 to 27.5° (mean 188.77, SD 6.21) were studied in 54 patients (mean age 67.81 y, SD 8.69) undergoing navigated TKA. Medial and lateral gaps in extension and at 90° of flexion were compared (using Independent-samples t test) between knees with valgus < 10° with those > 10° using a validated dynamic method after resection of cruciates, menisci and osteophytes, and then after final trialling.

of the soft-tissues after resection of cruciates, menisci, and osteophytes, with the knee flexed to 90°. These findings, highlighting the need for restoring flexion gap balance, may improve the inferior outcomes in valgus knees.

IV.Elastic recoil drives some of the fastest and most powerful biological movements. For effective use of elastic recoil, the tuning of muscle and spring force capacity is essential. Although studies of invertebrate organisms that use elastic recoil show evidence of increased force capacity in their energy loading muscle, changes in the fundamental properties of such muscles have yet to be documented in vertebrates. Here, we used three species of frogs (Cuban tree frogs, bullfrogs and cane toads) that differ in jumping power to investigate functional shifts in muscle-spring tuning in systems using latch-mediated spring actuation (LaMSA). We hypothesized that variation in jumping performance would result from increased force capacity in muscles and relatively stiffer elastic structures, resulting in greater energy storage. To test this, we characterized the force-length property of the plantaris longus muscle-tendon unit (MTU), and quantified the maximal amount of energy stored in elastic structures for each species. We found that the plantaris longus MTU of Cuban tree frogs produced higher mass-specific energy and mass-specific forces than the other two species. Moreover, we found that the plantaris longus MTU of Cuban tree frogs had higher pennation angles than the other species, suggesting that muscle architecture was modified to increase force capacity through packing of more muscle fibers. Finally, we found that the elastic structures were relatively stiffer in Cuban tree frogs. These results provide a mechanistic link between the tuned properties of LaMSA components, energy storage capacity and whole-system performance.ATP-binding cassette (ABC) transporters play an important role in various cellular processes. They display a similar architecture and share a mechanism which couples ATP hydrolysis to substrate transport. However, in the light of current data and recent experimental progress, this protein superfamily appears as multifaceted as their broad substrate range. Among the prokaryotic ABC transporters, MsbA can serve as a paradigm for research in this field. It is located in the inner membrane of Gram-negative bacteria and functions as a floppase for the lipopolysaccharide (LPS) precursor core-LPS, which is involved in the biogenesis of the bacterial outer membrane. While MsbA shows high similarity to eukaryotic ABC transporters, its expression in Gram-negative bacteria makes it conveniently accessible for many experimental approaches from spectroscopy to 3D structure determination. As an essential protein for bacterial membrane integrity, MsbA has also become an attractive target for the development of novel antibiotics. Furthermore, it serves as a model for multidrug efflux pumps. Here we provide an overview of recent findings and their relevance to the field, highlight the potential of methods such as solid-state NMR and EPR spectroscopy and provide a perspective for future work.
A debate is developing in Italy on the reform of the employment status of general practitioners. The dispute was prompted by the extraordinary resources the European Union has allocated to Italy on the condition of several structural reforms, among which lies the renewal of the primary care system. One of the most debated questions is whether general practitioners should become civil servants or remain autonomous workers. The issue is not only relevant to the quality and efficiency of primary care but is propitious for improving the legal certainty of this "hybrid figure" in Italian health law. The commentary suggests that, from a public law point of view, the employment status of civil servants better agrees with the foreseeable conditions of general practitioners working in Community Houses. In any case, national and regional policymakers must take into consideration possible controversies and litigation arising from an inappropriate qualification of the legal status of general practitioners in building tf general practitioners in building the new system of Italian primary care.
Bosnia and Herzegovina hasn't still developed and started any vaccination programs to contain the current COVID-19 outbreak and prevent further spreading and death from this disease. The aim of this study was to assess current knowledge, attitudes and practices towards COVID-19 vaccination during the third wave of the outbreak when the healthcare system is facing a collapse and to create a paradigm for developing vaccination programs in the country.

This cross-sectional study was conducted by an anonymous online questionnaire based on a Congo study and Center for Disease Control and Prevention facts regarding COVID-19 vaccination during the third wave of the COVID-19 outbreak in the country.

In total, 570 subjects, mostly female 474 (83.1%), with a high school degree or lower 230 (40.3%), married 305 (53.5%), engaged in intellectual labor 302 (53.0%), from urban environment 531 (93.1%) and with a mean age of 35.28±11.35, were included in the study. The mean COVID-19 vaccination knowledge test score was sitancy and further COVID-19 spreading and death toll. By activating proper socioepidemiological measures and educating population about COVID-19 and COVID- 19 vaccination, as well as vaccination against COVID-19, the current situation could be changed.
Our study shows that Bosnia and Herzegovina population has poor knowledge, relatively pessimistic attitudes and a very low vaccinal rate against COVID-19 during the third wave of the outbreak which promotes COVID-19 vaccination hesitancy and further COVID-19 spreading and death toll. By activating proper socioepidemiological measures and educating population about COVID-19 and COVID- 19 vaccination, as well as vaccination against COVID-19, the current situation could be changed.
The COVID-19 vaccination campaign began in Italy at the end of December 2020, with the primary aim of immunizing healthcare professionals, using the EMA approved mRNA vaccines (Comirnaty® by Pfizer/BioNTech; mRNA-1273 by Moderna) and recombinant adenoviral vaccine (Vaxzevria® by AstraZeneca). The study aimed at evaluating the prevalence and motivations underlying Vaccine Hesitancy, as well as the incidence and type of adverse events associated with COVID-19 vaccination.

Cross-sectional study. Data were collected January 1st to 28th 2021 using a purposely created online self-administered questionnaire from a selected cohort of Italian physicians.

Overall, 7,881 questionnaires were analyzed 6,612 physicians had received one dose, and 1,670 two doses of Comirnaty®; 30 had received one dose of mRNA-1273. Vaccine Hesitancy rate was 3.6%; it correlated with prior SARS-CoV-2 infection, diabetes, Adverse Eventss at previous vaccinations and refusal of 2020 flu vaccine, and was mainly motivated by concerns about vaccine Adverse Events. Typical Adverse Events were pain/itching/paresthesia at the inoculation site, followed by headache, fever, fatigue and myalgia/arthralgia occurring more frequently after the second dose (77.8 vs 66.9%; p<0.001), and in subjects with a prior SARS-CoV-2 infection.

Adherence to COVID-19 vaccination is high among physicians. Adverse Events are typically mild and more frequent in people with a prior SARS-CoV-2 infection.

Academic failure can negatively impact on the student, the university and the nursing workforce in the short term. The aim of this study is to analyze the characteristics and predictors of academic success in two cohorts of students of a Nursing Bachelor's Degree program.

This longitudinal study enrolled students who attended the Nursing Bachelor's Degree program. The Tor Vergata University includes 21 Nursing Bachelor's Degree programs at several Sanitary Institutions of the Rome area, with a mean annual recruitment of 800 students. We considered two cohorts of students beginning the program in the 2011-2012 and 2012-2013 academic years, respectively. The follow-up of these two cohorts ended in the 2017-2018 academic year. We considered socio-demographic and academic variables in the nursing field (pre-admission test grade, training exam grade in the first, second and third year and professional license exam grade). The outcome variable is academic success defined as graduation on time; academic failure is defined as changing degree, delay in completion of the course, attrition and dismissal (failure to complete the studies).
