Low‐normal birthweight in the first pregnancy as a risk factor for small for gestational age in the second pregnancy: A matched case–control study

Pregnancy, Volume 2, Issue 4, July 2026.
Abstract Background Recurrent obstetric complications may stem from chronic placental dysfunction or maternal vulnerability, with potential worsening across successive pregnancies. Subtle intrauterine growth restriction in a first pregnancy, even within the appropriate‐for‐gestational‐age (AGA) range, may signal underlying risk for subsequent adverse ...

Metastatic Gastric Adenocarcinoma Presenting With Pleuropericardial Effusions and Cardiac Tamponade: A Diagnostic Challenging Case Report

Respirology Case Reports, Volume 14, Issue 7, July 2026.
This case highlights the diagnostic challenge of occult gastric adenocarcinoma presenting with pleuropericardial effusions and tamponade. In unexplained lymphocyte‐predominant effusions, malignancy should be considered, and early VATS‐guided pleural biopsy may be required when noninvasive tests are inconclusive.

Spatial Transcriptomic Atlas Reveals That Forkhead Box O3‐Mediated Mitochondrial Dynamics Imbalance Drives Premature Ovarian Insufficiency in Mice

Aging Cell, Volume 25, Issue 7, July 2026.
This study constructed a spatial transcriptomic atlas of POI mouse ovaries and confirmed that decreased FOXO3 phosphorylation triggers mitochondrial dynamic disorder, granulosa cell senescence and ovarian dysfunction. FOXO3‐mitochondrial axis is a shared core mechanism in both drug‐induced POI and physiological ovarian aging, offering promising ...

Microtubule Inner Protein CFAP77 Contributes to Sperm Motility and Male Fertility in Mice

Andrology, Volume 14, Issue 5, Page 1240-1248, July 2026.
ABSTRACT Background Sperm motility is essential for male fertility, and its regulation is dependent on the structural integrity of the axoneme. The axoneme consists of a conserved “9+2” microtubule arrangement and is supported by microtubule inner proteins. However, the functional significance of many microtubule inner proteins remains unclear.

Computer‐Assisted Sperm Analysis (CASA) Versus Manual Evaluation and the Clinical Significance of Sperm Hyperactivated Motility

Andrology, Volume 14, Issue 5, Page 1401-1412, July 2026.
ABSTRACT Background Semen analysis remains the first‐line diagnostic test for male infertility, although it is affected by operator subjectivity. Computer‐assisted sperm analysis (CASA) is proposed to improve objectivity; however, its accuracy and clinical relevance remain uncertain.
