Background
Asthma remains highly prevalent, with more severe symptoms in low-income to middle-income countries (LMICs) compared with high-income countries. Identifying risk factors for severe asthma symptoms can assist with improving outcomes. We aimed to determine the prevalence, severity and ris...k factors for asthma in adolescents in an LMIC.
Methods
A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.
Results
A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.
Conclusion
Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.

Globally each year, millions of people suffer illness or lose their lives because the vaccines, medicines and diagnostic tests that they need are either unavailable or unaffordable – and this lack of access to medicine is acute in low- and middle-in-
come countries (LMICs). While the COVID-19 pan...demic laid this inequity bare, it also saw the pharmaceutical industry develop and bring new vaccines and treat- ments to market at unprecedented speed. As the world emerges from the worst
of this crisis, pharmaceutical companies are now at an important juncture, where lessons learned from the pandemic can prove pivotal in finding solutions to bridge long-standing gaps in access to medicine in LMICs.

It is Zika virus (ZIKV) that most often causes these neurological effects it appears to be the only arbovirus than can cause congenital malformations such as microcephaly. In any case, more scientific tests are needed to establish the causal relationship between the virus and this malformation (7-10...).
This document is a practical tool designed to help health workers improve clinical diagnosis and provide timely care for patients infected
with the dengue, chikungunya, or Zika virus. It is intended mainly for
health workers in primary care facilities where laboratory diagnosis of
arboviruses is not always available. However, this guide may also be
very useful in hospitals that provide second- and third-level care, as it
describes the clinical manifestations of each of the three most important
arboviral diseases currently found in the Region, the elements for
differential diagnosis, and their clinical behavior.

The report and an accompanying series of studies show the global uptake of the World Health Organization (WHO) Surgical Safety Checklist in its first ten years since its launch and recommend ways the Checklist can be more effectively used to improve surgical safety for millions at risk.
The report ...found that uptake has been remarkably positive: the Checklist has been adopted in almost 90% of operating rooms in countries with a high Human Development Index (HDI), a country-level measure of health, education, and standard of living. It was referenced by at least 139 (70%) of the world's countries and is included as a national standard by the health ministries of at least 20 countries. The Checklist has also had beneficial qualitative impact, introducing a culture of safety and improved communication within surgical teams, increasing patient trust, and improving job satisfaction.

The BRACED Myanmar Alliance was a three-year project aiming to ‘build the resilience of 350,000 people across Myanmar to climate extremes’. The project worked in 7 states, 8 townships and 155 communities. The main impact for project populations was intended to be ‘improved well-being and reduc...ed loss and damage despite climate shocks’, and the project sought to do this by addressing immediate hazard-related needs at community level while encouraging longer-term solutions driven and delivered by communities and subnational and national government.
Community Resilience Assessments (CRAs) were the first activities delivered as part of the project, and the list of community-identified needs became the basis from which local-level project interventions were selected. The selection typically involved an infrastructure requirement (linked to addressing a natural hazard, and sometimes shared between communities); a package of livelihood support (assets and trainings); capacity-building on climate change/resilience topics; and village savings and loans association (VSLA) support. A particular emphasis was placed on women’s empowerment, and leadership trainings and support to women’s self-help groups were provided.
