Age- and sex-stratified risks of myocarditis and pericarditis attributable to COVID-19 vaccination: A systematic review and meta-analysis.

While COVID-19 vaccines are generally very safe, the risks of myocarditis and pericarditis has been established following mRNA vaccines, with the highest risk in young males. Most systematic reviews and meta-analyses of the risk of myocarditis or pericarditis have included passive surveillance data, which is subject to reporting errors. Accurate measures of age-, sex-, vaccine dose-, and vaccine type-specific risks are crucial for assessment of the benefits and risks of the vaccination.

Comparison of methotrexate dosing protocols for graft-versus-host disease prophylaxis after unrelated hematopoietic stem cell transplantation.

Background Aims: Methotrexate (MTX) is used as standard graft-versus-host disease (GVHD) prophylaxis in allogeneic hematopoietic stem cell transplantation. However, the optimal dosing regimen among the various MTX regimens available remains unclear.

Methods: We used the registration data of Kyoto Stem Cell Transplantation Group to compare six MTX dosing protocols in a multicenter retrospective analysis of 816 cases of unrelated bone marrow or peripheral blood stem cell transplantation.

Risk of admission requirement among children with respiratory infection in the post-COVID-19 pandemic era.

Background: To evaluate the effect of the type and codetection of respiratory viruses on admission requirements among children with respiratory infections in the post-COVID-19 pandemic era.

Methods: In this retrospective study, we analyzed patients with acute respiratory symptoms using FilmArray® Respiratory Panel between December 2020 and March 2024. The viruses were classified into eight groups: adenovirus, seasonal coronavirus, human metapneumovirus, human rhinovirus/enterovirus, influenza virus, parainfluenza virus, respiratory syncytial virus, and severe acute respiratory virus coronavirus-2.

Evaluation of 3β-hydroxysteroid dehydrogenase activity using progesterone and androgen receptors-mediated transactivation.

3β-Hydroxysteroid dehydrogenases (3β-HSDs) catalyze the oxidative conversion of delta (5)-ene-3-beta-hydroxy steroids and ketosteroids. Human 3β-HSD type 2 (HSD3B2) is predominantly expressed in gonadal and adrenal steroidogenic cells for producing all classes of active steroid hormones. Mutations in HSD3B2 gene cause a rare form of congenital adrenal hyperplasia with varying degree of salt wasting and incomplete masculinization, resulting from reduced production of corticoids and androgens.

Polyploidy mitigates the impact of DNA damage while simultaneously bearing its burden.

Polyploidy is frequently enhanced under pathological conditions, such as tissue injury and cancer in humans. Polyploidization is critically involved in cancer evolution, including cancer initiation and the acquisition of drug resistance. However, the effect of polyploidy on cell fate remains unclear.

A Case of Spontaneous Regression of Adult Multi-system Langerhans Cell Histiocytosis Presenting as Liver Tumor Rupture.

Adult multisystem Langerhans cell histiocytosis (MS-LCH) is rare and has a poor prognosis. A 67-year-old man with MS-LCH presented with a hepatic tumor rupture and multiple masses in the lungs, liver, and pancreas. Despite the initial aggressive disease course and involvement of organs at risk, the patient experienced spontaneous regression and lesion disappearance following smoking cessation without chemotherapy.

Duration of PCR positivity by type of respiratory virus among children using a multiplex PCR test.

Prolonged positive polymerase chain reaction (PCR) results, irrespective of the transmission risk, can lead to prolonged restrictions on daily activities and infection precaution interventions. Studies evaluating the duration of PCR positivity for multiple pathogens in a single patient cohort are scarce. This study aimed to evaluate and compare the durations of PCR positivity for multiple respiratory viruses among children and adolescents.

Ozenoxacin suppresses sebum production by inhibiting mTORC1 activation in differentiated hamster sebocytes.

Acne vulgaris is a complex condition involving factors that affect the pilosebaceous unit. A primary manifestation of acne pathology is the development of comedones, often linked to the overproduction of sebum resulting from 5α-dihydrotestosterone (5α-DHT) and insulin activity. Ozenoxacin is a topical quinolone that exhibits potent antibacterial activity against Cutibacterium acnes (C.

The Role of TLR7 and TLR9 in the Pathogenesis of Systemic Sclerosis.

The bleomycin-induced scleroderma model is a well-established and dependable method for creating a mouse model of SSc (systemic sclerosis). In the field of skin connective tissue diseases, increasing evidence from clinical and animal experiments suggests that TLRs (Toll-like receptors) play an important role in several diseases. This study aimed to determine the role of TLR7 (Toll-like receptor 7) and TLR9 (Toll-like receptor 9) in the mechanisms of immune abnormalities and fibrosis in SSc.

promotes zygotic genome activation upon loss of .

Once fertilized, mouse zygotes rapidly proceed to zygotic genome activation (ZGA), during which long terminal repeats (LTRs) of murine endogenous retroviruses with leucine tRNA primer (MERVL) are activated by a conserved homeodomain-containing transcription factor, DUX. However, -knockout embryos produce fertile mice, suggesting that ZGA is redundantly driven by an unknown factor(s). Here, we present multiple lines of evidence that the multicopy homeobox gene, , encodes a transcription factor that is highly expressed in mouse two-cell embryos and redundantly drives ZGA.

Background: There are no sex-specific guidelines for chronic aortic regurgitation (AR). This retrospective study examined sex-specific differences and propose treatment criteria from an Asian AR cohort.

Methods and results: Consecutive 1,305 patients with moderate-severe AR or greater at 3 tertiary centers in Taiwan and Japan (2008-2022) were identified.

The impact of single-stranded RNAs on the dimerization of double-stranded RNA-dependent protein kinase PKR.

The RNA-binding protein PKR serves as a crucial antiviral innate immune factor that globally suppresses translation by sensing viral double-stranded RNA (dsRNA) and by phosphorylating the translation initiation factor eIF2α. Recent findings have unveiled that single-stranded RNAs (ssRNAs), including in vitro transcribed (IVT) mRNA, can also bind to and activate PKR. However, the precise mechanism underlying PKR activation by ssRNAs, remains incompletely understood.
