Scale up and strengthening of comprehensive emergency obstetric and newborn care in Tanzania.

Introduction: In Tanzania, inadequate access to comprehensive emergency obstetric and newborn care (CEmONC) services is the major bottleneck for perinatal care and results in high maternal and perinatal mortality. From 2015 to 2019, the Accessing Safe Deliveries in Tanzania project was implemented to study how to improve access to CEmONC services in underserved rural areas.

Methods: A five-year longitudinal cohort study was implemented in seven health centres (HCs) and 21 satellite dispensaries in Morogoro region.

Screening for depression in children and adolescents: a protocol for a systematic review update.

Background: Major depressive disorder is common, debilitating, and affects feelings, thoughts, mood, and behaviors. Childhood and adolescence are critical periods for the development of depression and adolescence is marked by an increased incidence of mental health disorders. This protocol outlines the planned scope and methods for a systematic review update that will evaluate the benefits and harms of screening for depression in children and adolescents.

Surface-emitting electroholographic SAW modulator.

We report the design and operation of a surface-emitting surface acoustic wave (SAW) acousto-optical modulator which behaves as a cm-scale linear hologram in response to an applied electronic waveform. The modulator is formed by an optical waveguide, transducer, and out-coupling surface grating on a 1 mm-thick lithium niobate substrate. We demonstrate the ability to load and illuminate a 9-region linear hologram into the modulator's 8 mm-long interaction region using applied waveforms of 280-320 MHz.

Preterm birth and the future risk of orthopedic fracture.

Background: Preterm birth occurs during a critical period of bone mineralization. We assessed whether preterm birth increases the risk of childhood fracture.

Methods: We analyzed a cohort of 788,903 infants born between 2006 and 2016 in Quebec, Canada.

Screening for depression in women during pregnancy or the first year postpartum and in the general adult population: a protocol for two systematic reviews to update a guideline of the Canadian Task Force on Preventive Health Care.

Background: In 2018, the World Health Organization reported that depression is the most common cause of disability worldwide, with over 300 million people currently living with depression. Depression affects an individual's physical health and well-being, impacts psychosocial functioning, and has specific negative short- and long-term effects on maternal health, child health, developmental trajectories, and family health. The aim of these reviews is to identify evidence on the benefits and harms of screening for depression in the general adult population and in pregnant and postpartum women.

Knowledge acquisition after Helping Babies Survive training in rural Tanzania.

Background: While the effectiveness of Helping Babies Breathe (HBB) training in Tanzania has been reported, no published studies of Essential Care for Every Baby (ECEB) and Essential Care for Small Babies (ECSB) in this setting have been found. This study compared knowledge before and after HBB, ECEB and ECSB training in Tanzania.

Methods: Training was provided to future facilitators (n=16) and learners (n=24) in Tanzania.

Magnetic field imaging with microfabricated optically-pumped magnetometers.

A multichannel imaging system is presented, consisting of 25 microfabricated optically-pumped magnetometers. The sensor probes have a footprint of less than 1 cm and a sensitive volume of 1.5 mm × 1.

Major Depressive Disorder Among Preadolescent Canadian Children: Rare Disorder or Rarely Detected?

Objective: Despite agreement that preadult onset of depression is associated with greater illness severity, and that children can meet the diagnostic criteria for major depressive disorder (MDD), few studies have examined the presentation of MDD among young children. This is the first nationwide study of MDD among preadolescent children in Canada.

Methods: Pediatrician members (2500) of a Canadian pediatric surveillance network were surveyed monthly over 3 years to report new cases of MDD among 5- to 12-year-olds.

Long-Term Effects of Education and Legislation Enforcement on All-Age Bicycle Helmet Use: A Longitudinal Study.

Bicycle-related injuries are a leading cause of child and youth hospitalizations in Canada. The use of helmets while bicycling reduces the risk of brain injuries. This study investigated the long-term effect of legislation coupled with enforcement to improve helmet use rates.

Maternal depression and malnutrition in children in southwest Uganda: a case control study.

Background: Malnutrition remains one of the most significant child health problems in developing countries with an estimated 53% of child deaths per year attributed to being underweight. The 2011 Uganda Demographic and Health Survey (UDHS) showed that 38 % of the children were stunted and 16% were underweight. While dietary and environmental factors are known major contributors to children's nutritional status, maternal depression may also contribute since it disrupts the mothers' ability to cope with demands of childcare.

Fetal magnetocardiography measurements with an array of microfabricated optically pumped magnetometers.

Following the rapid progress in the development of optically pumped magnetometer (OPM) technology for the measurement of magnetic fields in the femtotesla range, a successful assembly of individual sensors into an array of nearly identical sensors is within reach. Here, 25 microfabricated OPMs with footprints of 1 cm(3) were assembled into a conformal array. The individual sensors were inserted into three flexible belt-shaped holders and connected to their respective light sources and electronics, which reside outside a magnetically shielded room, through long optical and electrical cables.

Early repair of congenital heart disease associated with increased rate of attention deficit hyperactivity disorder symptoms.

Background: As more children survive with congenital heart disease, their neurodevelopmental outcomes (including attention deficit hyperactivity disorder [ADHD]) are becoming increasingly important. The objective of our study was to determine if school-aged children who underwent early cardiac surgery for congenital heart disease are more likely than healthy control subjects to have screening scores on the Swanson, Nolan, and Pelham IV (SNAP-IV) questionnaire suggestive of ADHD.

Methods: Children aged 7-15 years who underwent open-heart surgery before 1 year of age were identified from the Izaak Walton Killam (IWK) Children's Heart Centre Database.

The CYRM-12: a brief measure of resilience.

Objectives: This article details the reduction of the Child and Youth Resilience Measure (CYRM) from a 28-item to a 12-item measure. The CYRM-28 is a measure of youth resilience that accounts for cultural and contextual diversity across youth populations. A reduced version of the CYRM is better suited to inclusion in omnibus surveys.
