Summary: Some interaction-powered supernovae have long rise times of more than 100 days. If the circumstellar matters (CSM) have a flat density structure (s ≥ 1.5, where s is the exponent of CSM), such long rise times are naturally expected. In this case, the bolometric luminosities from the CSM interaction keep increasing as long as the CSM interacts with the outer layers of the SN ejecta. Thus, the rise time is determined by the dynamical time-scale in which the reverse shock propagates the outer layers of the SN ejecta, not by the time-scales in which photons diffuse in the CSM as often considered. Interaction-powered supernovae with very long rise times can be an important probe of extensive non-steady mass-loss in massive stars.

Summary: A wind-driven model is used to model the observational properties of transients powered by continuous outflow from a central system. This study introduces a time-dependent wind-driven model that considers the expanding outflow and time evolution of the outflow rate. The model is applied to a sample of well-observed fast blue optical transients (FBOTs) and suggests that FBOTs may be related to relativistic objects such as black holes.

Summary: Gyrochronology can provide useful ages for field main-sequence stars, especially in situations where other techniques are problematic. In this study, the performance of existing gyrochronology relations is tested by constructing samples of stellar pairs with coeval components. Results show that wide binaries and cluster members are in better agreement with gyrochronology compared to randomly paired field stars, but the agreement decreases for older stars, indicating the need for revised calibrations.

Summary: Superhumps are variable phenomena observed in cataclysmic variables, coming in positive and negative flavors. Positive superhumps are common in short-period dwarf novae while negative superhumps are not preference for a particular type. This study utilizes TESS's long high-cadence light curves to analyze superhump behavior in old novae and novalike variables, resulting in the most comprehensive census of superhumps in these stars. Furthermore, eclipse epochs derived from the TESS light curves are used to update orbital ephemeris and discuss period changes.

Summary: This article presents a study of 34 red giant candidate members of NGC 188 using WIYN1/Hydra spectra, which, in combination with WOCS2 and Gaia data, identifies different categories of members. The study reports a [Fe/H] value of +0.064 +/- 0.018 dex for NGC188 and makes improvements in the line list near Li 6707.8 angstrom. The study argues that all four stars can be considered Li-rich in the context of the cluster and discusses possible sources of lithium in each star.

Summary: The cardiovascular system is frequently affected by COVID-19, particularly in hospitalized cases, leading to complications such as myocarditis and pulmonary embolism. Early detection through imaging techniques such as CT scan and MRI is important for prompt disease recognition and evaluation. The immune system's abnormal response is responsible for severe COVID-19 and organ-specific injury, with molecular mimicry possibly being the immunological mechanism for myocarditis in COVID-19.

Summary: The immune system plays a crucial role in maintaining tissue homeostasis and defending against pathogens and cancer cells. However, the aging process leads to a decline in immune function, resulting in compromised immune responses and unresolved inflammation. This contributes to a subclinical syndrome of homeostatic frailty in the elderly, making them more susceptible to immune debilitation and chronic low-grade inflammation, which in turn increase the risk of chronic and degenerative diseases. This review focuses on the age-dependent changes in myeloid populations and their impact on frailty and diseases in the elderly.

Summary: This systematic review and meta-analysis aimed to investigate the correlation between isolated serum antinuclear antibody (ANA) and infertility in IVF, idiopathic recurrent pregnancy losses (RPL), and pregnancy complications in the second/third trimester. The study found that ANA-positive women undergoing IVF had a lower pregnancy rate and a higher miscarriage rate compared to ANA-negative women. In terms of RPL, there was a higher prevalence of ANA-positivity. However, the effect of serum ANA on late pregnancy complications was inconclusive.

Summary: An important issue often ignored is the discrepancy in medical treatment response between male and female genders. COVID-19 vaccine administration has revealed that females tend to experience more adverse events compared to males despite following identical protocols. Through logistic regression analysis of adverse events in 2385 healthcare workers receiving the Comirnaty vaccine, we found that age, sex, COVID-19 history, and BMI may contribute to the development of adverse events, particularly in young subjects, females, and individuals with a BMI below 25 kg/m(2). Furthermore, partial dependence plots indicate a 50% probability of mild adverse events lasting for a long period (>= 7 days) or any duration of severe adverse events in women below 40 years old with a BMI < 20 kg/m(2). Given that this effect is more prominent after the second vaccine dose, we propose adjusting the vaccine dosage for additional booster doses based on age, sex, and BMI to reduce adverse events without compromising vaccine efficacy.

Summary: Rheumatoid arthritis (RA) is an autoimmune disease characterized by synovitis, and interstitial lung disease (RA-ILD) is a common extra-articular feature. The mechanisms and predictors of RA-ILD are limited, and early identification is crucial for timely treatment. New biomarkers, imaging techniques, and diagnostic pathways are needed for better management of RA-ILD.

Summary: Progressive pulmonary fibrosis is diagnosed when interstitial lung disease progresses without any other causes, and some myositis patients with associated interstitial lung disease may develop this condition. Autoantibodies increase the risk of pulmonary fibrosis in myositis, and serum biomarkers can predict pulmonary involvement and the early identification of progressive pulmonary fibrosis. The association between anti-Ro52 and pulmonary fibrosis in patients with inflammatory myositis has been supported by previous evidence.

Summary: Nonbacterial thrombotic endocarditis (NBTE) is a type of endocarditis that occurs in patients with predisposing conditions, commonly referred to as marantic or Libman-Sacks endocarditis. The clinical presentation involves embolic events, with fewer valvular complications compared to infective forms of endocarditis. The diagnosis is primarily based on echocardiography, with comprehensive microbiological and serological tests to exclude infective endocarditis.
