Background: There is increasing evidence of an elevated sex ratio at birth (SRB) in many Asian countries, including Vietnam, and that this prenatal gender inequity is related to sex-selective abortion. However, few studies have investigated the relation between the sex of offspring and delivery care utilization.
Objective: The aim of the present study was to relate sex of newborns to place and mode of delivery in a province in northern Vietnam.
Methods: A population-based surveillance system within the Neonatal Health-Knowledge Into Practice (NeoKIP) project (ISRCTN44599712) recorded all births within eight districts of Quang Ninh province in northern Vietnam from July 2008 to June 2011.
Results: In total, there were 22,377 live births within the study area. SRB was 108 boys per 100 girls. There was a large difference in SRB depending on place of delivery, with 94 boys per 100 girls being delivered at home, whereas 113 boys per 100 girls were delivered at a district-level hospital. Cesarean section (CS) rate was 17%, and within the CS group, the SRB was 135:100.
Conclusions: We demonstrated an elevated SRB, especially at district hospital level, and that sex of offspring influenced place and mode of delivery. Although mothers to boys were more likely to receive more qualified delivery care, they were at the same time more likely to undergo unnecessary surgery. Correct information to women and family members about CS and stricter implementation of the medical indications for CS are urgently called for.

This work describes fully integrated multifolding electrochemical paper-based devices (ePADs) for enhanced multiplexed voltammetric determination of heavy metals (Zn(II), Cd(II), and Pb(II)) using tunable passive preconcentration. The paper devices integrate five circular sample preconcentration layers and a 3-electrode electrochemical cell. The hydrophobic barriers of the devices are drawn by pen-plotting with hydrophobic ink, while the electrodes are deposited by screen-printing.

Introduction Following the COVID-19 pandemic, there was adoption of virtual psychotherapy. There are a number of benefits and drawbacks to telehealth video conferencing that are experienced by both clients and clinicians. The current qualitative study sought to outline the advantages and disadvantages that clients and clinicians have personally experienced in virtual versus in-person therapy in an effort to identify the reasons for which one medium may be preferred over another.

A novel silica-based material (SBM), synthesized from chemically-, thermally-, and mechanically-treated blast furnace slag (TBFS), was examined for its batch-mode lead adsorption capacity based on various parameters. Physicochemical examinations revealed that the formulation of the new SBM consisted mainly of silica, which represented 81.79% of its total composition.

Purpose: Variations in neural survival along the cochlear implant electrode array leads to off-place listening, resulting in poorer speech understanding outcomes for recipients. Therefore, it is important to develop and compare clinically viable tests to identify these patient-specific intra-cochlear neural differences.
Methods: Nineteen experienced cochlear implant recipients (9 males and 10 females) were recruited for this study.

In the case of repeated loadings, the reliability of inertial microelectromechanical systems (MEMS) can be linked to failure processes occurring within the movable structure or at the anchors. In this work, possible debonding mechanisms taking place at the interface between the polycrystalline silicon film constituting the movable part of the device and the silicon dioxide at the anchor points are considered. In dealing with cyclic loadings possibly inducing fatigue failure, a strategy is proposed to optimize the geometry of an on-chip testing device designed to characterize the strength of the aforementioned interface.
