No test medical abortion - a review of the evidence on selective use of preabortion testing.

Purpose Of Review: The last decade has seen a cascade of different telemedicine models for medical abortion (MA) being tested and implemented. Among these service delivery models is the 'no-test' MA model, in which care is provided remotely and eligibility for the MA is based on history alone. The purpose of this review is to provide an overview of the existing evidence for no-test MA.

Managing assessment during curriculum change: Ottawa Consensus Statement.

Curriculum change is relatively frequent in health professional education. Formal, planned curriculum review must be conducted periodically to incorporate new knowledge and skills, changing teaching and learning methods or changing roles and expectations of graduates. Unplanned curriculum evolution arguably happens continually, usually taking the form of "minor" changes that in combination over time may produce a substantially different programme.

Determinants of Choice of Facility-Based Delivery among Mothers in Kwara State, Nigeria.

Background: Nigeria has the highest number of maternal deaths in the world, which is a major public health problem. One of the major contributory factors is high prevalence of unskilled birth attendance from low facility delivery. However, the reasons for and against facility delivery are complex and not fully understood.

Scoping Review of Predisposing Factors Associated with Sensorineural Hearing Loss in Sickle Cell Disease.

Purpose: Sickle cell disease (SCD) is a genetically inherited red blood cell disorder that affects people all over the world but is more common among blacks of African ancestry than other races. The condition is linked to sensorineural hearing loss (SNHL). This scoping review aims to evaluate studies that reported SNHL in SCD patients and to identify demographic and contextual risk factors for SNHL in SCD patients.

An ISN-DOPPS Survey of the Global Impact of the COVID-19 Pandemic on Peritoneal Dialysis Services.

Introduction: Home dialysis may minimize SARS-CoV2 exposure risks compared to center-based dialysis. We explored how the pandemic may have introduced challenges related to peritoneal dialysis (PD) supply availability, routine patient care, and how facility practices changed during this time.

Methods: The PD/Dialysis Outcomes and Practice Patterns Study (PDOPPS/DOPPS) and International Society of Nephrology (ISN) administered a web-based survey from November 2020 to March 2021.

The Impact of COVID-19 on Neurosurgical Services in Africa.

Introduction: COVID-19 has affected the global provision of neurosurgical services. We sought to review the impact of COVID-19 on the neurosurgical services in Africa.

Methods: A cross-sectional survey was distributed to African neurosurgeons seeking to review demographics, national and neurosurgical preparedness, and change in clinical services in April 2020.

Taxonomy of the complex. III. The revision of South African species of and (Collembola, Isotomidae).

Species of the genera of the complex in South Africa are morphologically revised. Five new species of the genus Willem, 1902 and one new species of the genus Delamare Deboutteville, 1948 are described. and have only one chaeta on the anterior side of dens and no chaetae on the anterior side of manubrium, the latter species being characterized by the presence of a bulb at apex of antennae; shows a rare combination of eight ocelli on each side of the head with a tridentate mucro; has five long s-chaetae on the fifth abdominal segment; is unique by having a very long and slender postantennal organ with strong inner denticles; is the second member of the genus and differs from the type species by many more anterior chaetae on the manubrium and the presence of chaetae on ventral side of metathorax.

Implementation barriers for mHealth for non-communicable diseases management in low and middle income countries: a scoping review and field-based views from implementers.

: Mobile health (mHealth) has been hailed as a potential gamechanger for non-communicable disease (NCD) management, especially in low- and middle-income countries (LMIC). Individual studies illustrate barriers to implementation and scale-up, but an overview of implementation issues for NCD mHealth interventions in LMIC is lacking. This paper explores implementation issues from two perspectives: information in published papers and field-based knowledge by people working in this field.

Dynamic balance and ankle injury odds: a prospective study in 196 Dutch physical education teacher education students.

Objective: The aim of this study was to investigate whether dynamic balance, measured with the anterior component of the Star Excursion Balance Test (SEBT-ANT), is a risk factor for ankle injuries in physical education teacher education (PETE) students.

Design And Setting: A prospective monocentre study in first-year PETE students.

Participants: A total of 196 subjects, of which 137 men (70%) and 59 women (30%).

The Lysosomal Sequestration of Tyrosine Kinase Inhibitors and Drug Resistance.

The Lysosomal sequestration of weak-base anticancer drugs is one putative mechanism for resistance to chemotherapy but it has never been directly proven. We addressed the question of whether the lysosomal sequestration of tyrosine kinase inhibitors (TKIs) itself contributes to the drug resistance in vitro. Our analysis indicates that lysosomal sequestration of an anticancer drug can significantly reduce the concentration at target sites, only when it simultaneously decreases its extracellular concentration due to equilibrium, since uncharged forms of weak-base drugs freely diffuse across cellular membranes.

Lenses and levels: the why, what and how of measuring health system drivers of women's, children's and adolescents' health with a governance focus.

Health systems are critical for health outcomes as they underpin intervention coverage and quality, promote users' rights and intervene on the social determinants of health. Governance is essential for health system endeavours as it mobilises and coordinates a multiplicity of actors and interests to realise common goals. The inherently social, political and contextualised nature of governance, and health systems more broadly, has implications for measurement, including how the health of women, children and adolescents health is viewed and assessed, and for whom.

Awareness and Knowledge Associated with Autism Spectrum Disorders Among University Students in Zambia.

Experiences with Autism Spectrum Disorders (ASDs) in sub-Saharan Africa are characterized with lots of uncertainty, including lack of awareness and knowledge. This study examined ASD awareness and knowledge among 488 University of Zambia undergraduate students using an autism awareness and knowledge survey. Study findings on awareness revealed a high proportion of students-seventy-nine percent (79%) had never heard of ASD before the survey.

BioTIME: A database of biodiversity time series for the Anthropocene.

Motivation: The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community-led open-source database of biodiversity time series.

The learning environment in remediation: a review.

Background: The focus of this concise article is how best to support students to achieve success at medical school. Our aim is not to provide a guide to remediating under-performance in medical students. This, in our view, implies an approach that fundamentally is about quick fixes for addressing individual student deficits, such as intensive coaching of clinical skills to help a student scrape through a resit examination.

Converging on child mental health - toward shared global action for child development.

We are a group of researchers and clinicians with collective experience in child survival, nutrition, cognitive and social development, and treatment of common mental conditions. We join together to welcome an expanded definition of child development to guide global approaches to child health and overall social development. We call for resolve to integrate maternal and child mental health with child health, nutrition, and development services and policies, and see this as fundamental to the health and sustainable development of societies.

Proper-motion age dating of the progeny of Nova Scorpii AD 1437.

'Cataclysmic variables' are binary star systems in which one star of the pair is a white dwarf, and which often generate bright and energetic stellar outbursts. Classical novae are one type of outburst: when the white dwarf accretes enough matter from its companion, the resulting hydrogen-rich atmospheric envelope can host a runaway thermonuclear reaction that generates a rapid brightening. Achieving peak luminosities of up to one million times that of the Sun, all classical novae are recurrent, on timescales of months to millennia.

The prevalence of pulmonary complications after thoracic and abdominal surgery and associated risk factors in patients admitted at a government hospital in Harare, Zimbabwe-a retrospective study.

Background: The burden of HIV/AIDS in Sub-Saharan Africa has presented unusual and challenging acute surgical problems across all specialties. Thoraco-abdominal surgery cuts through muscle and thereby disrupts the normal anatomy and activity of the respiratory muscles leading to reduced lung volumes and putting the patients at greater risk of developing post-operative pulmonary complications (PPCs). PPCs remain an important cause of post-operative morbidity, mortality, and impacts on the long-term outcomes of patients post hospital discharge.

The social patterning of risk factors for noncommunicable diseases in five countries: evidence from the modeling the epidemiologic transition study (METS).

Background: Associations between socioeconomic status (SES) and risk factors for noncommunicable diseases (NCD-RFs) may differ in populations at different stages of the epidemiological transition. We assessed the social patterning of NCD-RFs in a study including populations with different levels of socioeconomic development.

Methods: Data on SES, smoking, physical activity, body mass index, blood pressure, cholesterol and glucose were available from the Modeling the Epidemiologic Transition Study (METS), with about 500 participants aged 25-45 in each of five sites (Ghana, South Africa, Jamaica, Seychelles, United States).

Improvements in ECG accuracy for diagnosis of left ventricular hypertrophy in obesity.

Objectives: The electrocardiogram (ECG) is the most commonly used tool to screen for left ventricular hypertrophy (LVH), and yet current diagnostic criteria are insensitive in modern increasingly overweight society. We propose a simple adjustment to improve diagnostic accuracy in different body weights and improve the sensitivity of this universally available technique.

Methods: Overall, 1295 participants were included-821 with a wide range of body mass index (BMI 17.
