The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

Extreme heat events (EHEs) are a leading cause of weather-related injury and death in the United States, and under a changing climate, these meteorological episodes are predicted to increase in both frequency and intensity. Prolonged heat exposure from EHEs places an increased strain on the heart an...d may lead to heat-related illness if the cardiovascular system fails to properly thermoregulate internal body temperature. Every individual is susceptible to heat-related illness, however, those with reduced cardiovascular function and pre-existing cardiovascular diseases are at a greater risk for morbidity and mortality during EHEs. This document gives an overview of our current understanding of heat exposure and its impact on cardiovascular health outcomes, an overview of the medications that may exacerbate heat-related cardiovascular illness, and asummary of the interaction between extreme heat and air pollutants, and their collective impact on cardiovascular health. Additionally, this document summarizes epidemiologic evidence and identifies gaps in the extant peer-reviewed literature on the effectiveness of strategies and interventions to protect against heat-related cardiovascular disease and death. This information is intended to aid health departments and other health professionals in understanding and responding to the impacts of heat exposure on cardiovascular health.

Yemen’s war has become one of the world’s worst humanitarian catastrophes . In September 2014, the Ansarallah (Houthi) movement allied with former President Ali Abdullah Saleh to seize control over the capital city Sana’a and renegotiate Yemen’s fragile power-sharing agreement, and then seve...ral months later pursued President Abed Rabbo Mansour Hadi south to Aden . In March 2015, Saudi Arabia and the United Arab Emirates launched a military intervention, ostensibly to restore Hadi to power . More than 1,000 days later, that war has settled into a brutal stalemate . Officially, the Houthis remain in control of Sana’a and much of the north, while the Saudi-UAE coalition controls much of the south . A comprehensive Saudi-UAE blockade and air campaign has caused incipient famine conditions, the spread of communicable diseases such as cholera and diphtheria, and a wave of internal displacement .

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.

AMR is one of the Key priority of the global health security agenda action package, as well as it is one of the commitments of Ministry of Public Health Afghanistan to combat AMR. In Afghanistan because of war and some other political issues the borders of the country are not well secured and well c...ontrolled therefore control of smuggling of medicine is a big challenge in front of the rational use of medicine. Lack of knowledge (professionals and public), poor economic state, conflict of war, presence of remote areas and etc…. are the other main challenges for this to won the battle of combating AMR.

Everyday experience shows that there is a commonality between spirituality and medical practice. A text message I received from a friend recently read, "Please pray for me. I've been getting a mysterious headache for some days now. I will be seeing the doctor today." This clearly speaks of a relatio...nship: asking for prayer so as to be relieved of a "mysterious headache", yet going to see a doctor whose job is not to cure mysterious headaches. Even though both areas of human experience have their peculiar and largely unrelated methodologies, this paper argues that any extreme separation of the two is injurious to the teleology of both disciplines in relation to human well-being, which forms the core of spirituality and medicine.

Background: Community health worker (CHW) programmes are a valuable component of primary care in resource-poor settings. The evidence supporting their effectiveness generally shows improvements in disease-specific outcomes relative to the absence of a CHW programme. In this study, we evaluated expan...ding an existing HIV and tuberculosis (TB) disease-specific CHW programme into a polyvalent, household-based model that subsequently included non-communicable diseases (NCDs), malnutrition and TB screening, as well as family planning and antenatal care (ANC).
Methods: We conducted a stepped-wedge cluster randomised controlled trial in Neno District, Malawi. Six clusters of approximately 20 000 residents were formed from the catchment areas of 11 healthcare facilities. The intervention roll-out was staggered every 3 months over 18 months, with CHWs receiving a 5-day foundational training for their new tasks and assigned 20–40 households for monthly (or more frequent) visits.
Findings: The intervention resulted in a decrease of approximately 20% in the rate of patients defaulting from chronic NCD care each month (−0.8 percentage points (pp) (95% credible interval: −2.5 to 0.5)) while maintaining the already low default rates for HIV patients (0.0 pp, 95% CI: −0.6 to 0.5). First trimester ANC attendance increased by approximately 30% (6.5pp (−0.3, 15.8)) and paediatric malnutrition case finding declined by 10% (−0.6 per 1000 (95% CI −2.5 to 0.8)). There were no changes in TB programme outcomes, potentially due to data challenges.

Background
Cardiovascular diseases (CVDs) are one of the global leading causes of concern due to the rising prevalence and consequence of mortality and disability with a heavy economic burden. The objective of the current study was to analyze the trend in CVD incidence, mortality, and mortality-to-...incidence ratio (MIR) across the world over 28 years.
Methods
The age-standardized CVD mortality and incidence rates were retrieved from the Global Burden of Disease (GBD) Study 2017 for both genders and different world super regions with available data every year during the period 1990–2017. Additionally, the Human Development Index was sourced from the United Nations Development Programme (UNDP) database for all countries at the same time interval. The marginal modeling approach was implemented to evaluate the mean trend of CVD incidence, mortality, and MIR for 195 countries and separately for developing and developed countries and also clarify the relationship between the indices and Human Development Index (HDI) from 1990 to 2017.
Results
The obtained estimates identified that the global mean trend of CVD incidence had an ascending trend until 1996 followed by a descending trend after this year. Nearly all of the countries experienced a significant declining mortality trend from 1990 to 2017. Likewise, the global mean MIR rate had a significant trivial decrement trend with a gentle slope of 0.004 over the time interval. As such, the reduction in incidence and mortality rates for developed countries was significantly faster than developing counterparts in the period 1990–2017 (p < 0.05). Nevertheless, the developing nations had a more rather shallow decrease in MIR compared to developed ones.
Conclusions
Generally, the findings of this study revealed that there was an overall downward trend in CVD incidence and mortality rates, while the survival rate of CVD patients was rather stable. These results send a satisfactory message that global effort for controlling the CVD burden was quite successful. Nonetheless, there is an urgent need for more efforts to improve the survival rate of patients and lower the burden of this disease in some areas with an increasing trend of either incidence or mortality.

In 2017, $37.4 billion of development assistance was provided to low- and middleincome countries to maintain or improve health. This amount is down slightly compared to 2016, and since 2010, development assistance for health (DAH) has grown at an annualized rate of 1.0%. While global development ass...istance for health has seemingly leveled off, global health spending continues to climb, outpacing economic growth in many countries. Total health spending for 2015, the most recent year for which data are available, was estimated to be $9.7 trillion (95% uncertainty interval: 9.7–9.8)*, up 4.7% (3.9–5.6) from the prior year, and accounted for 10% of the world’s total economy. With some sources of health spending growing and other types remaining steady, and with major variations in spending from country to country, it is more important than ever to understand where resources for health come from, where they go, and how they align with health needs. This information is critical for planning and is a necessary catalyst for change as we aim to close the gap on the unfinished agenda of the Millennium Development Goals (MDGs) and move forward toward universal health coverage (UHC) in the Sustainable Development Goals (SDGs) era.

This document focuses on the management of patients affected by gambiense HAT and
constitutes an update to the WHO therapeutic guidance issued in 2013. The main changes in recommendations concern the criteria and methods for deciding the treatment among the new set of therapeutic options and the pa...rticular conditions that apply to treatment with fexinidazole, as outlined below. Because HAT is a serious, life-threatening disease and because the efficacy of fexinidazole depends on swallowing the medicine after an appropriate intake of food as well as on completing the full 10-day
treatment schedule, the recommendations regarding fexinidazole administration are considered key elements that must be carefully followed. When the conditions listed in these guidelines are not met for any individual patient, the alternative available treatments should be prescribed.

The Food and Agriculture Organization of the United Nations has launched a new Compendium of forgotten foods in Africa which is a first-of-its-kind comprehensive collection of 100 African forgotten food crops.
Also referred to as neglected, underutilized or orphan crops, these species offer valua...ble benefits, including nutrition and diet diversification, while supporting resilient, climate-smart agriculture but they are at risk of being lost as foods such as maize, rice and wheat dominate African diets.
The compendium list includes details on each crop's botanical classification, agroecological suitability, agronomic requirements, traditional and medicinal uses, value-added prospects and nutritional content. Among the entries are: African locust beans, African nightshade, baobab, Bambara nut, bush mango, cassava, fonio, marula, moringa, teff and tigernut.
Produced by the Food and Agriculture Organization (FAO)'s Regional Office for Africa with the Forum for Agricultural Research in Africa (FARA), the Compendium is a direct response to the UN Food Systems Summit and the Call for Collective Action in the Global Manifesto on Forgotten Foods.
Embracing both agricultural heritage and innovation can transform agrifood systems across Africa. By cataloguing these forgotten or underutilized crops, traditional knowledge is being honoured in the push to unlock the potential for better nutrition, sustainable agriculture, and resilience against the climate crisis.
In a joint foreword to the publication, FAO Assistant Director-General and Regional Representative for Africa Abebe Haile-Gabriel and FARA Executive Director Aggrey Agumya urged the mainstreaming of forgotten foods into African agrifood systems.

En los últimos cinco años y como parte del ciclo programático humanitario, se han identificado las personas con necesidades en Colombia (anual) en un esfuerzo conjunto de los socios del Equipo Humanitario de País, en coordinación con otras contrapartes del Estado. La afectación histórica de m...illones de personas por diferentes emergencias humanitarias, como consecuencia del conflicto, la violencia y eventos de desastres naturales, ha requerido la presencia e intervención complementaria al Estado, por parte de organizaciones humanitarias tanto nacionales como internacionales. Después de cuatro años de Diálogos de Paz entre el Gobierno y las FARC-EP se dio la firma de un Acuerdo, el cual debía también representar el alivio humanitario en muchas regiones golpeadas; no obstante, el deterioro de la situación humanitaria interna en Colombia, se refleja en más de 5.1 millones de personas con necesidades, como lo podremos evidenciar en este documento.
