We investigated fetal development and the estimation of fetal age of 127 Hokkaido sika deer fetuses, categorizing them into three groups according to the nutritional condition of populations. The order and time of the appearance of ossification centers were clarified, and fetal age was determined based on bone length and the appearance of ossification centers. Then we observed the differences in fetal growth among three populations, and discussed the effect of poor nutrition on the fetal growth. The results suggest that fetal diaphysial length of the femur was affected very little by nutritional conditions, whereas conception dates were delayed and fetal weight was restricted as the nutritional condition became poorer. Although it is impossible to know the exact accurate fetal age in wild populations, it was possible to create a standard to estimate fetal age more precisely by the method described in this study. Both the bone length and the appearance of ossification centers are reliable indices to estimate fetal age precisely in measurements available from fetuses of unknown age, and can be applied to estimate the fetal age of other populations of sika deer, whereas estimation of fetal age based on weight is prone to great errors.

Background And Hypothesis: It is unclear if low birth weight (LBW), preterm birth and small for gestational age (SGA) could synergistically cause chronic kidney disease (CKD) and end-stage kidney disease (ESKD). This cohort study was conducted to examine their individual and combined impacts on the development of CKD and ESKD in childhood.
Methods: From the Taiwan Maternal and Child Health Database, we identified 1 477 128 newborns born between January 1, 2009, and December 31, 2016.

Background & Aims: The health-related quality of life (HRQoL) during pregnancy has not been well-lidated in mothers with chronic hepatitis B (CHB). We aim to compare patient-reported outcomes (PROs) in CHB mothers with those of healthy mothers during pregnancy.
Methods: Between 4/16/2023 and 7/31/2023, we invited consecutive CHB and healthy mothers to complete the self-administered 36-item Short Form Survey (SF-36) and the Chronic Liver Disease Questionnaire (CLDQ) for PRO assessment.
Introduction: A recent scoping review identified histological chorioamnionitis (HCA), small for gestational age (SGA), and bubbly/cystic appearance on chest X-ray (bubbly/cystic CXR) as risk factors for severe bronchopulmonary dysplasia (BPD). To further validate these results, a large-scale database was analyzed.
Methods: This retrospective multicenter cohort study included infants born at <28 weeks' gestational age between 2003 and 2016.

Microelectrodes offer exceptional sensitivity, rapid response, and versatility, making them ideal for real-time detection and monitoring applications. Photoelectrochemical (PEC) sensors have shown great value in many fields due to their high sensitivity, fast response, and ease of operation. Nevertheless, conventional PEC sensing relies on cumbersome external light sources and bulky electrodes, hindering its miniaturization and implantation, thereby limiting its application in real-time disease monitoring.

Introduction: Intrauterine devices (IUDs) are highly effective contraceptives. Despite their effectiveness, pregnancies can occur during IUD use, and the management of such cases, particularly when the pregnancy is desired, remains controversial.
Material And Methods: We conducted a systematic review and meta-analysis to evaluate outcomes in women who unintentionally conceived while using IUDs and chose to continue their pregnancies.
