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.

2nd edition. WHO's recommendation has not changed: the standard WHO susceptibility tests should remain a primary method by which resistance is detected. However, it was considered necessary to update the existing resistance-monitoring procedures to also highlight the need for operationally meaningfu...l data.
Two new assays were included in this expanded version: an intensity assay and a synergist assay.

Snakebites are well-known medical emergencies in many parts of the world, especially in rural areas. Agricultural workers and children are the most affected. The incidence of snakebite mortality is particularly high in South-East Asia. Rational use of snake anti-venom can substantially reduce mortal...ity and morbidity due to snakebites. These guidelines are a revised and updated version of Regional Guidelines for the Management of snakebites published by the WHO Regional Office in South-East Asia in 2011. These guidelines aim to promote the rational management of snakebite cases in various health facilities where trained health functionaries and quality snake antivenom are available.

Low and middle income countries (LMICs) are facing an increase of the impact of mental health problems while confronted with limited resources and limited access to mental health care, known as the ‘me...ntal health gap’. One strategy to reduce the mental health gap would be to utilize the internet to provide more widely-distributed and low cost mental health care. We undertook this systematic review to investigate the effectiveness and efficacy of online interventions in LMICs.

Low- and middle-income countries (LMICs) experience a high disease burden for epilepsy, a chronic neurological condition.The authors evaluate the cost-effectiveness of community health workers (CHWs) to improve adherence to medication for epilepsy in South Africa. They found that utilizing CHWs to i...mprove medication adherence was cost-effective.

WHO recommends prompt recognition of progressive acute hypoxaemic respiratory failure when a patient with respiratory distress is failing to respond to standard oxygen therapy and adequate preparation to provide advanced oxygen/ventilatory support.
Hypoxaemic respiratory failure in ARDS commonly ...results from intrapulmonary ventilation-perfusion mismatch or shunt and usually requires mechanical ventilation.
At any time, if there are urgent or emergent indications for intubation, do not delay.
We recommend prompt recognition of progressive acute hypoxaemic respiratory failure when a patient with respiratory distress is failing to respond to standard oxygen therapy and adequate preparation to provide advanced oxygen/ventilatory support.
WHO suggests that patients with severe or critical COVID-19 with acute hypoxaemic respiratory failure that do not require emergent intubation be treated with HFNO, or CPAP or NIV (BiPAP) over standard oxygen therapy.

Antimicrobial Resistance (AMR) occurs when organisms that cause disease are no longer susceptible/responsive to antimicrobial agents that previously were effective in combating them. AMR is a global problem with particularly dire consequences for Africa which is already grappling with high levels ...of infection in the face of limited resources.

In the last quarter of 2019 Southern African Regional Interagency Standing Committee Africa (RIASCO) reported that more than 11 million people were experiencing crisis or emergency levels of food insecurity in nine Southern African countries1 due to deepening drought and climate related crisis. The ...Southern African Development Community (SADC) urged for urgent humanitarian action, and at the beginning of November 2019 Angola, Botswana, Lesotho and Namibia had declared states of drought emergencies, requiring international assistance to address the worsening food insecurity situation.

The epidemiology of wheeze in children, when assessed by questionnaires, is dependent on parents' understanding of the term “wheeze”.
In a questionnaire survey of a random population sample of 4,236 children aged 6–10 yrs, parents' definition of wheeze was assessed. Predictors of a correct ...definition were determined and the potential impact of incorrect answers on prevalence estimates from the survey was assessed.
Current wheeze was reported by 13.2% of children. Overall, 83.5% of parents correctly identified “whistling or squeaking” as the definition of wheeze; the proportion was higher for parents reporting wheezy children (90.4%). Frequent attacks of reported wheeze (adjusted odds ratio (OR) 3.0), maternal history of asthma (OR 1.5) and maternal education (OR 1.5) were significantly associated with a correct answer, while the converse was found for South Asian ethnicity (OR 0.6), first language not English (OR 0.6) and living in a deprived neighbourhood (OR 0.6).
In summary, the present study showed that misunderstanding could lead to an important bias in assessing the prevalence of wheeze, resulting in an underestimation in children from South Asian and deprived family backgrounds. Prevalence estimates for the most severe categories of wheeze might be less affected by this bias and questionnaire surveys on wheeze should incorporate measures of parents' understanding of the term wheeze.

Injury to the skin and underlying tissues from acute exposure to
a large external dose of radiation is referred to as cutaneous
radiation injury (CRI). Acute radiation syndrome (ARS) 1 will
usually be accompanied by some skin damage; however, CRI
can ...occur without symptoms of ARS. This is especially true with
acute exposures to beta radiation or low-energy x-rays, because
beta radiation and low-energy x-rays are less penetrating and less
likely to damage internal organs than gamma radiation is. CRI can
occur with radiation doses as low as 2 Gray (Gy) or 200 rads 2 and
the severity of CRI symptoms will increase with increasing doses.
Most cases of CRI have occurred when people inadvertently came
in contact with unsecured radiation sources from food irradiators,
radiotherapy equipment, or well depth gauges. In addition, cases of
CRI have occurred in people who were overexposed to x-radiation
from fluoroscopy units.

The global emergence of antimicrobial resistance (AMR) is posing a threat to human health. Putting resources into the containment of AMR – including surveillance – is one of the highest-yield investments a country can make to mitigate its impact. In 2015, WHO launched the Global Antimicrobial Re...sistance Surveillance System (GLASS), the first global collaborative effort to foster AMR surveillance in bacteria causing acute infections. As of December 2018, 71 countries are enrolled in GLASS. The aim of this report is to document participation efforts and outcomes across these countries, and highlight differences and constraints identified to date. This report follows on from the first GLASS Report – Early implementation 2016-17, published in January 2018, and drawing on data from GLASS first data call in 2017.
