The cellular microenvironment contributes to the architecture, differentiation, polarity, mechanics and functions of the cell [1]. Spatial confinement of cells using micropatterning techniques allows to alter and regulate the cellular microenvironment for a better understanding of cellular mechanisms [2]. However, commercially available micropatterned consumables such as coverslips, dishes, plates etc. are expensive. These methods are complex and based on deep UV patterning [3,4]. In this study, we establish a low-cost method for effective micropatterning using Polydimethylsiloxane (PDMS) chips.•We demonstrate this method by generating fibronectin-coated micropatterned lines (width, 5 µm) on a glass bottom dish.•As a proof of concept, we culture macrophages on these lines. We additionally show that this method allows to determine the cellular polarity by measuring the position of the nucleus within a cell on a micropatterned line.

Experiences of African women who migrate to a developed country and encounter intimate partner violence: a systematic review of qualitative evidence.
JBI Evid Synth
January 2025
School of Nursing and Midwifery, University of Newcastle, Newcastle, New South Wales, Australia.
Objective: The objective of this review was to synthesize the available evidence on the experiences of African women who migrated to a developed country and encountered intimate partner violence (IPV).
Introduction: IPV is a significant public health issue, and migrant women living in developed countries are particularly vulnerable to IPV, experiencing disproportionately higher rates of IPV. Understanding the experiences of these women can inform health policy and decision-making in clinical practice to minimize IPV.
Impact of Frailty on Antihypertensive Treatment in Older Adults.
Hypertension
January 2025
The George Institute for Global Health, Faculty of Medicine, University of New South Wales, Newtown, Australia (L.C., S.Y., N.E., M.W., T.L., Y.G., C.S.A., K.H., X.C., R.P.).
Background: The association between systolic blood pressure and all-cause mortality differs between frail and nonfrail individuals, highlighting uncertainties about the effectiveness of antihypertensive treatments in frail populations.
Methods: Using data from the SHEP trial (Systolic Hypertension in the Elderly Program), a baseline frailty index (FI), including 55 variables, was constructed. Fine-Gray subdistribution hazard models and Cox proportional hazards regression models were used to explore the association between baseline FI and the risks of stroke, cardiovascular disease, and all-cause death, as well as to examine whether the impact of antihypertensive treatment on these outcomes was modified by baseline FI.
Determinants of Racial and Ethnic Differences in Maternal Cardiovascular Health in Early Pregnancy.
Circ Cardiovasc Qual Outcomes

Department of Preventive Medicine, Northwestern University Feinberg School of Medicine, Chicago, IL. (N.A.C., X.H., L.C.P., H.N., N.S.S., A.M.P., P.G., D.M.L.-J., K.N.K., S.S.K.).
Background: Suboptimal cardiovascular health (CVH) in pregnancy is associated with adverse maternal and offspring outcomes. To guide public health efforts to reduce disparities in maternal CVH, we determined the contribution of individual- and neighborhood-level factors to racial and ethnic differences in early pregnancy CVH.
Methods: We included nulliparous individuals with singleton pregnancies who self-identified as Hispanic, non-Hispanic Black (NHB), or non-Hispanic White (NHW) and participated in the nuMoM2b cohort study (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be).
Validation Status of Electronic Sphygmomanometers in China: A National Survey.
Hypertension
January 2025
Clinical Research Institute, Institute of Advanced Clinical Medicine, Peking University, Beijing, China (X.Z., W.X., Y.W.).
Background: Although the information on the validation status of electronic sphygmomanometer (ES) devices in use in health care institutions and households is much more clinically relevant than that of ES models available on the market, it remains insufficient.
Methods: A national survey was conducted across all administrative regions of mainland China to assess the validation status of ESs. Fifty-eight cities were selected with stratification by municipality, provincial capital, and other cities, and health care institutions and households in each city were chosen by convenience to identify ES devices in use according to the study protocol.
Reductive Removal of Antimony from Wastewater by a UV/Sulfite Process: Targeted Recovery of Strategic Metalloid Antimony.

The removal of antimony from wastewater using traditional methods such as adsorption and membrane filtration generates large amounts of antimony-containing hazardous wastes, posing significant environmental threats. This study proposed a new treatment strategy to reductively remove and recover antimony from wastewater using an advanced UV/sulfite reduction process in the form of valuable strategic metalloid antimony (Sb(0)), thus preventing hazardous waste generation. The results indicated that more than 99.
