Jointly enclosed in-between: the collective meaning of liminality in refugees' and other migrants' mental health care.

People on the move are increasingly immobilised between and within state borders, having left 'there' but not allowed to be fully 'here'. This paper presents a nuanced examination of this state of enforced in--betweenness, exploring how refugees and other migrants negotiate collective existence through, despite, and alongside liminality. Drawing on ethnographic data collected at a Swiss Red Cross psychotraumatology centre, the study identifies factors that impede and facilitate the formation of collective identities, with temporal and spatial liminality emerging as the most central collective experience for refugees and other migrants. The findings illustrate how therapists reinforce these bonds by fostering an idealised sense of therapeutic communitas that promotes unity in adversity. However, the paper refrains from reducing the collective significance of liminality to a mere act of defiance. Instead, it critically reflects on how refugees and other migrants forge collective connections within politically and legally imposed disconnection. It accounts for the paradox of refugees and other migrants making collective lives in liminality while confronting the always-imminent possibility of this very liminality dismantling their lives.

Chronic hepatitis C virus infections in Switzerland in 2020: Lower than expected and suggesting achievement of WHO elimination targets.

In this multi-method study, we investigated the prevalence of chronic infections with the hepatitis C virus (HCV) in Switzerland in 2020, and assessed Switzerland's progress in eliminating HCV as a public health problem by 2030 with regard to the World Health Organization (WHO) criteria targeting infections acquired during the preceding year ('new transmissions') and HCV-associated mortality. Based on a systematic literature review, the reappraisal of a 2015 prevalence analysis assuming 0.5% prevalence among the Swiss population and data from many additional sources, we estimated the prevalence among subpopulations at increased risk and the general population. For new transmissions, we evaluated mandatory HCV notification data and estimated unreported new transmissions based on subpopulation characteristics. For the mortality estimate, we re-evaluated a previous mortality estimate 1995-2014 based on new data on comorbidities and age. We found a prevalence of ≤0.1% among the Swiss population. Discrepancies to the 2015 estimate were explained by previous (i) underestimation of sustained virologic response numbers, (ii) overestimation of HCV prevalence among PWID following bias towards subgroups at highest risk, (iii) overestimation of HCV prevalence among the general population from inclusion of high-risk persons and (iv) underestimation of spontaneous clearance and mortality. Our results suggest that the WHO elimination targets have been met 10 years earlier than previously foreseen. These advancements were made possible by Switzerland's outstanding role in harm-reduction programmes, the longstanding micro-elimination efforts concerning HIV-infected MSM and nosocomial transmissions, little immigration from high-prevalence countries except Italian-born persons born before 1953, and wealth of data and funding.

Adjusted COVID-19 booster schedules balance age-dependent differences in antibody titers benefitting risk populations.

We provide follow-up data on the humoral immune response after COVID-19 vaccinations of two distinct cohorts aged below 60 and over 80 years to screen for age-related differences in the longevity and magnitude of the induction of the antibody responses post booster-vaccinations. While anti-SARS-CoV-2 spike-specific IgG and neutralization capacity waned rapidly after the initial vaccination schedule, additional boosters highly benefitted the humoral immune responses especially in the elderly cohort, including the neutralization of Omikron variants. Thus, adjusted COVID-19 booster vaccination schedules are an appropriate tool to overcome limitations in the success of vaccinations.

Sex differences in 24-hour ultra-marathon performance--a retrospective data analysis from 1977 to 2012.

OBJECTIVES: This study examined the changes in running performance and the sex differences between women and men in 24-hour ultra-marathons held worldwide from 1977 to 2012. METHOD: Changes in running speed and ages of the fastest 24-hour ultra-marathoners were determined using single- and multi-level regression analyses. RESULTS: From 1977 to 2012, the sex differences in 24-hour ultra-marathon performance were 4.6±0.5% for all women and men, 13.3% for the annual fastest finishers, 12.9±0.8% for the top 10 and 12.2±0.4% for the top 100 finishers. Over time, the sex differences decreased for the annual fastest finishers to 17%, for the annual 10 fastest finishers to 11.3±2.2% and for the annual 100 fastest finishers to 14.2±1.8%. For the annual fastest men, the age of peak running speed increased from 23 years (1977) to 53 years (2012). For the annual 10 and 100 fastest men, the ages of peak running speed were unchanged at 40.9±2.5 and 44.4±1.1 years, respectively. For women, the ages of the annual fastest, the annual 10 fastest and the annual 100 fastest remained unchanged at 43.0±6.1, 43.2±2.6 and 43.8±0.8 years, respectively. CONCLUSION: The gap between the annual top, annual top 10 and annual top 100 female and male 24-hour ultra-marathoners decreased over the last 35 years; however, it seems unlikely that women will outrun men in 24-hour ultra-marathons in the near future. The fastest 24-hour ultra-marathoners worldwide achieved their peak performance at the age of master athletes (>35 years).
