Objective: The aim: To investigate changes in the characteristics of menstrual function in women after suffering from Covid-19 or vaccination against SARS-CoV-2.
Patients And Methods: Materials and methods: After the retrospective analysis of 378 medical records patients were divided into: Group 1 (177 women) with menstrual function disorders (MFD) after COVID-19, Group 2 (121 women) with MFD after SARS-CoV-2 vaccination, Group C (80 women) without MFD after COVID-19 or vaccination (controls). The study focused on the clinical and hormonal menstrual cycle characteristics and factors influencing MFD.
Results: Results: Dyshormonal thyroid disorders were observed in 63.0% of Group 1 and 45.7% of Group 2 patients; hyperprolactinemia - in 31.0% and 39.4%, hyper¬estrogenia - in 50% and 21%, and hyperandrogenism - in 39% and 20%. MFD was associated with hyperandrogenism with concurrent hyperprolactinemia, in the context of thyroid dysfunction; and with changes of gonadotropin production, along with normal and elevated estrogen concentrations and worsening of mental health that suggest disruption of central regulatory and feedback mechanisms in the pituitary-thyroid-ovarian system under the stressors influence.
Conclusion: Conclusions: There are changes in the menstrual cycle associated with disruption of the hypothalamus-pituitary-ovary system and thyroid function in women after suffering from Covid-19 or vaccination. To reestablish reproductive homeostasis, employing a personalized diagnostic strategy is recommended, encompassing the evaluation of thyroid gland status, hormonal profiling, and the consideration of psychosocial facets.

Since the precursor frequency of naive T cells is extremely low, investigating the early steps of antigen-specific T cell activation is challenging. To overcome this detection problem, adoptive transfer of a cohort of T cells purified from T cell receptor (TCR) transgenic donors has been extensively used but is not readily available for emerging pathogens. Constructing TCR transgenic mice from T cell hybridomas is a labor-intensive and sometimes erratic process, since the best clones are selected based on antigen-induced CD69 upregulation or IL-2 production in vitro, and TCR chains are polymerase chain reaction (PCR)-cloned into expression vectors.

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.

Bullous pemphigoid (BP) is a debilitating autoimmune skin blistering disease, characterized by the deposition of specific autoantibodies at the dermal-epidermal junction. This leads to an inflammatory cascade involving the activation of complement proteins, mast cell degranulation, immune cell recruitment, and the release of proteases by granulocytes. While several cytokines and signaling pathways have been implicated in the pathogenesis of BP, the precise mechanism behind autoantibody production remains unclear.

The global epidemic of bovine coronavirus (BCoV) has caused enormous economic losses. The characterisation and genetic composition of endemic strains in Southwest China remain elusive. This study aimed to fill this gap by isolating three BCoV strains from this region and sequencing their whole genomes.

Background: This study aimed to assess the antibody response to SARS-CoV-2 vaccines among healthcare workers (HCWs) from multiple outpatient clinics in Japan, examining the effects of baseline characteristics (e.g., sex, age, underlying condition, smoking history, occupation) and prior infections.
