Background: Little attention has been placed on the unique iron demands that may exist in women with multiple gestations. This merits attention because iron deficiency (ID) during pregnancy is associated with adverse pregnancy outcomes that are known to be more prevalent in multiple births.
Objective: We characterized longitudinal changes in iron status across pregnancy in a cohort of healthy women with multiple gestations and identified determinants of maternal ID and anemia.
Design: A group of 83 women carrying twins, triplets, or quadruplets (aged 20-46 y) was recruited from 2011 to 2014. Blood samples obtained during pregnancy (∼24 wk; n = 73) and at delivery (∼35 wk; n = 61) were used to assess hemoglobin, serum ferritin (SF), soluble transferrin receptor (sTfR), hepcidin, serum iron, erythropoietin, serum folate, vitamin B-12, C-reactive protein, and interleukin-6.
Results: The prevalence of tissue ID (sTfR >8.5 mg/L) increased significantly from pregnancy to delivery (9.6% compared with 23%, P = 0.03). Women with depleted iron stores (SF <12 μg/L, n = 20) during pregnancy had a 2-fold greater risk of anemia at delivery, and 25% (n = 5) developed iron deficiency anemia (IDA). Overall, 44.6% of women studied (n = 37/83) were anemic at delivery, and 18% of women (n = 11/61) had IDA. Erythropoietin during pregnancy was significantly negatively associated with hemoglobin at delivery. Women with erythropoietin >75th percentile during pregnancy exhibited a 3-fold greater risk of anemia, suggesting that erythropoietin is a sensitive predictor of anemia at delivery. Inflammation was present at delivery, which limited the utility of ferritin or hepcidin as iron-status indicators at delivery.
Conclusions: ID and anemia are highly prevalent in women with multiple gestations. Additional screening and iron supplementation may be warranted in this high-risk population given the known associations between ID anemia and adverse maternal and neonatal outcomes. This trial was registered at clinicaltrials.gov as NCT01582802.

Background: The involvement of undergraduate medical students in research is pivotal for the advancement of evidence-based clinical practice. This study aimed to assess the extent of research involvement and the factors influencing it among undergraduate medical students in Bangladesh.
Methods: A multi-center cross-sectional study involving 2864 medical students from both public and private medical colleges was conducted between June and December 2023.

Background: This study aimed to explore the relationship of cervical tumor lesion location (CTLL) with bilateral parametrial involvement (PI) and pelvic lymph node metastasis (LNM).
Methods: The study retrospectively analyzed the clinicopathologic and imaging data of patients with cervical squamous cell carcinoma (SCC) retrieved from multiple centers. According to the CTLL, patients were allocated to three groups: a middle one third group, a unilaterally dominant group, and the entire-region group.

Background: Despite prior observational studies suggesting a link between gut microbiota to Kawasaki disease (KD), these findings remain debated. This study aimed to assess the association between gut microbiota and KD on a genetic level using a two-sample Mendelian randomization (MR) analysis.
Methods: This two-sample MR analysis utilized summary statistics from the largest genome-wide association study meta-analysis on gut microbiota conducted by the MiBioGen consortium.

In Brazil, health policies implemented over the last three decades have enabled rapid testing for HIV to be made available in primary health care services. However, although these policies are national, the implementation of actions is not uniform, as they depend on the local management of local health systems. In this context, the study identified the proportion of women from sexual minorities who had never tested for HIV and the factors associated with access, in a Metropolitan Region of the Brazilian Amazon.

Introduction: The UK national pediatric diabetes audit reports higher HbA1c for children and young people (CYP) with type 1 diabetes (T1D) of Black ethnicity compared with White counterparts. This is presumably related to higher mean blood glucose (MBG) due to lower socioeconomic status (SES) and less access to technology. We aimed to determine if HbA1c ethnic disparity persists after accounting for the above variables.
