Myocardial infarctions are generally clinically classified into ST elevation MI (STEMI) and non-ST elevation MI (NSTEMI), based on changes in ECG. When blood flow to a part of the heart stops or the heart is injured and fails to receive enough oxygen required for its adequate functioning the conditi...on is termed as STEMI or the ‘heart-attack’ in laymen language. Patients with elevated cardiac troponin levels but negative CK-MB who were formerly diagnosed with unstable angina or minor myocardial injury are now reclassified as non-ST-segment elevation Myocardial Infarction (non-STEMI) even in the absence of diagnostic changes.

The article "Barriers and determinants of asthma control in children and adolescents in Africa: a systematic review" analyzes factors contributing to poor asthma control in African youth. Based on studies conducted between 2014 and 2019 in Nigeria, Uganda, and South Africa, the review identifies key... challenges such as limited access to asthma diagnosis, inadequate use of inhaled corticosteroids, and environmental and socio-economic factors. It finds that urban living, older age, and concurrent allergic conditions significantly affect asthma management. The study emphasizes the need for improved diagnostic tools, better access to treatment, and tailored public health interventions to enhance asthma outcomes in African children.

The article is a scoping review that explores the challenges in diagnosing asthma in children in three sub-Saharan African countries: Nigeria, South Africa, and Uganda. It identifies key barriers, such as a lack of community awareness, inadequate healthcare access, limited diagnostic tools like spir...ometry, and insufficient knowledge among healthcare workers. The review also highlights the stigma associated with asthma and the absence of relevant diagnostic guidelines. Solutions proposed include community education, development and adherence to diagnostic guidelines, and strengthening healthcare systems. The study aims to inform policymakers and healthcare providers to improve asthma diagnosis and care for children in these regions.

Background: Cardiovascular disease (CVD), mainly heart attack and stroke, is the
leading cause of premature mortality in low and middle income countries (LMICs).
Identifying and managing individuals at high risk of CVD is an important strategy to prevent and control CVD, in addition to multisector...al population-based interventions to reduce CVD risk factors in the entire population.
Methods: We describe key public health considerations in identifying and managing individuals at high risk of CVD in LMICs.
Results: A main objective of any strategy to identify individuals at high CVD risk is to maximize the number of CVD events averted while minimizing the numbers of
individuals needing treatment. Scores estimating the total risk of CVD (e.g. ten-year risk of fatal and non-fatal CVD) are available for LMICs, and are based on the main CVD risk factors (history of CVD, age, sex, tobacco use, blood pressure, blood cholesterol and diabetes status). Opportunistic screening of CVD risk factors enables identification of persons with high CVD risk, but this strategy can be widely applied in low resource settings only if cost effective interventions are used (e.g. the WHO Package of Essential NCD interventions for primary health care in low resource settings package) and if treatment (generally for years) can be sustained, including continued availability ofaffordable medications and funding mechanisms that allow people to purchase medications without impoverishing them (e.g. universal access to health care). Thisalso emphasises the need to re-orient health systems in LMICs towards chronic diseases management.
Conclusion: The large burden of CVD in LMICs and the fact that persons with high
CVD can be identified and managed along cost-effective interventions mean that
health systems need to be structured in a way that encourages patient registration, opportunistic screening of CVD risk factors, efficient procedures for the management of chronic conditions (e.g. task sharing) and provision of affordable treatment for those with high CVD risk. The focus needs to be in primary care because that is where most of the population can access health care and because CVD programmes can be run effectively at this level.

For the first time, this year’s report includes information on hepatitis C diagnostics. With a focus on selected countries with diverse HCV epidemics, the report provides updates on the various dimensions of access to HCV diagnostics and pha...rmaceutical products, including product pricing, the regulatory environment and patent status, which together shape the national hepatitis response in different settings. It highlights key areas for action by ministries of health and other government decision-makers, pharmaceutical manufacturers and technical partners.

Following review of the latest evidence, WHO recommends that TB-LAMP can be used as a replacement for microscopy for the diagnosis of pulmonary TB in adults with signs and symptoms of TB. It can also be considered as a follow-on test to microscopy in adults with signs and symptoms of pulmonary TB, e...specially when further testing of sputum smear-negative specimens is necessary.

Brief Repor
The overall objective of this implementation plan is to define the strategy for implementation of the Xpert MTB/RIF test for rapid detection of TB and rifampicin (RIF) resistance in Tanzania, within the context of the National Tuberculosis and Leprosy Programme (NTLP) strategic plan and other nation...al health guidelines. It is intended to serve as the main guiding document for national, regional and local programme managers, clinicians, coordinators, laboratory staff and other health workers; national and regional reference laboratories; local and international implementing partners; and donors involved in TB control.

Three classess of tests are now recommended in the latest consolidated guideles on tests for tuberculosis infection. It includes for the first-time a new class of Mycobacterium tuberculosis antigen-based skin tests (TBSTs), and the two existing classes of tests: the tuberculin skin test (TST) and t...he interferon-gamma release assays (IGRAs).
IGRAs and TBSTs use Mycobacterium tuberculosis complex specific antigens and represent a significant advancement to TST which has been used for over half a century.

This document provides a systematic approach in developing a coordinated, standardized, reliable, efficient, cost-effective, and sustainable specimen transport and referral system to support IVHD and VL testing networks. This document provides technical and programmatic recommendations on the approp...riate specimen storage and transportation of specimens for HIV VL and IVHD testing. Along with the national guidelines for specimen storage and transport, these standards should provide guidance on the creation or improvement of specimen referral networks and specimen transport systems. In addition, standard operating procedures (SOPs) targeting drivers and persons responsible for packing of specimens and results return are included in this document.
