Background: University entrance is accompanied by major changes in social relationship, rules, and expectations that lead to psychological disorders in susceptible students. The goal of this research is to study the anxiety rate in Iranian medical residents in 2010-2011.
Methods: This study is a cross-sectional, descriptive study. It contains 370 medical residents from the 1(st) year to the 4(th) year of medical universities in Isfahan, Gilan, Zahedan, Sanandaj, and Kashan. The stratified sampling method proportionate to volume of participants is used in this study. The information is collected based on researchers' questioners and Zung self-rating anxiety scale and analyzed with the use of spss software version 16, addition to descriptive and analytic tests (Pearson, one-way analysis of variance, t-test). Meaningful level is regarded as P ≤ 0.05.
Results: The study showed that more than 92% of residents participated in the study did not demonstrate anxiety. Among 370 subjects 5.5% presented with mild symptoms of anxiety and no one had symptom of severe anxiety. A meaningful statistical relationship was observed between anxiety and sex, major of study and the city of study (P < 0.05). The results showed a positive meaningful relationship between the number of visits and the score of anxiety. On average the number of night floats were two in 1 week and the number of patient visit was 19 in the past 24 h. A meaningful statistical relationship between anxiety score and number of patient visits was observed.
Conclusions: The anxiety rate in medical students in this study compared to the findings of previous studies reveled very low anxiety in medical residents. The low rate of anxiety could be attributed to the sense of job security and the hope for a better future among residents. The high percentage of anxiolytics abuse and absence of anxiety producing factors among residents in addition to inaccurate response to the questionnaire may all contribute to the low rate of anxiety in this study.

This study quantifies the impact of COVID-19 vaccination on hospitalization for COVID-19 infection in a South African private health insurance population. This retrospective cohort study is based on the analysis of demographic and claims records for 550,332 individuals belonging to two health insurance funds between 1 March 2020 and 31 December 2022. A Cox Proportional Hazards model was used to estimate the impact of vaccination (non-vaccinated, partly vaccinated, fully vaccinated) on COVID-19 hospitalization risk; and zero-inflated negative binomial models were used to estimate the impact of vaccination on hospital utilization and hospital expenditure for COVID-19 infection, with adjustments for age, sex, comorbidities and province of residence.

Guanylate binding proteins (GBPs) are large interferon-inducible GTPases, executing essential host defense activities against Toxoplasma gondii, an invasive intracellular apicomplexan protozoan parasite of global importance. T. gondii establishes a parasitophorous vacuole (PV) which shields the parasite from the host's intracellular defense mechanisms.

Chemical modification of naturally derived glycosaminoglycans (GAGs) expands their potential utility for applications in soft tissue repair and regenerative medicine. Here we report the preparation of a novel crosslinked chondroitin sulfate (~200 to 2000 kilodaltons) that is both soluble in aqueous solution and microfilterable. We refer to these materials as "SuperGAGs.
