The aim of this study was to develop vitamin D (VD) and iron (Fe) blended granules using Neusilin® US2 as an excipient. A central composite design of experiments was used for the continuous manufacturing process, considering VD and iron as independent variables and the bulk density, flow index, oil holding capacity, and color difference as response variables. The addition of VD had a significant effect on the powder flow properties. The X-ray diffraction and Scanning electron microscopy-energy dispersive X-ray analysis validated the presence of VD and Fe in the granules, whereas the variations in porosity and roughness were demonstrated by tomography and atomic force microscopy, respectively. The in vitro cellular uptake profile confirmed the absorption of VD in the breast cancer cell line MCF-7 with apparent apoptosis. These results could help in scaling up the process from laboratory to pilot scale in twin-screw granulation and boost the intervention of VitD/iron deficiencies.

Background: Overweight and obesity-chronic illnesses in which an increase in body fat promotes adipose tissue dysfunction and abnormal fat mass resulting in adverse metabolic, biomechanical, and psychosocial health consequences-negatively impact female fertility. Adverse conception outcomes are multifactorial, ranging from poor oocyte quality and implantation issues to miscarriages and fetal health issues. However, with the advent of novel pharmacologic agents, significant weight loss can be achieved, improving the chances of healthy pregnancies, and their use should be considered during periconceptual counseling.

This study was an original article, mainly aimed to explore the influence of nutritional guidance during pregnancy on nutritional status and pregnancy outcome of pregnant women. Two hundred (200) pregnant women were admitted to the Nanjing General Hospital of Nanjing Military Command from May 2021 to May 2023. They were randomly sub-divided into a control group and an intervention group.

Introduction: The increasing adoption of strict vegetarian diets during pregnancy has raised concerns about their effects on maternal and neonatal outcomes. This systematic review and meta-analysis aimed to assess the impact of strict vegetarian diets on key pregnancy outcomes, including neonatal birth weight, small-for-gestational-age (SGA) infants, gestational diabetes mellitus (GDM), hypertensive disorders, and gestational weight gain (GWG).
Methods: A comprehensive literature search across multiple databases yielded eight studies from various countries, involving a total of 72,284 participants.

Anemia is a critical medical condition in public health concern in tropical and subtropical areas, and understanding its hematological changes is crucial for improving diagnosis, treatment, and prognosis.It manifests through symptoms like weakness, fatigue, pale skin, and shortness of breath due to insufficient hemoglobin or red blood cells to carry adequate oxygen, with severe cases leading to complications such as chest pain. Common causes include blood loss, chronic diseases, and iron and vitamin deficiencies.

Background: Evaluation of primary care allows for identification of problems in the healthcare system, such as poor health outcomes, inappropriate health services, overuse of unnecessary resources, or underuse of recommended strategies. Assessment of adherence to existing clinical practice guidelines as quality indicators is critical for evaluating the effectiveness of primary care and shaping healthcare policies.
Objectives: To determine the adherence of primary care providers to existing practice guidelines for common pediatric concerns in remote, rural, and urban areas in the Philippines.
