Desde hace muchas décadas, los microbios, en particular las bacterias, se han vuelto cada vez más resistentes a diversos antimicrobianos. El aval de la Asamblea Mundial de la Salud al Plan de Acción Mundial sobre la resistencia a los antimicrobianos, en mayo de 2015, y la Declaración política d...e la reunión de alto nivel de la Asamblea General sobre la resistencia a los antimicrobianos, en septiembre de 2016, reconocen que la resistencia a los antimicrobianos es una amenaza para la salud pública mundial. Estas iniciativas políticas reconocen el uso excesivo e inapropiado de los antimicrobianos como el principal factor que favorece dicha resistencia, así
como la necesidad de optimizar el uso de estos medicamentos.

The World Health Organization (WHO) convened a meeting of the Technical Advisory Group on Buruli ulcer at its headquarters in Geneva, Switzerland on 25 to 27 March 2019
WHO’s sentinel surveys of acquired HIV resistance to dolutegravir among people receiving dolutegravir-containing antiretroviral therapy is intended for easy and frequent implementation. Results from sentinel surveys provide insight into the prevalence and year-over-year trends of dolutegravir resi...stance in adults, children and adolescents receiving dolutegravir-based ART.
This sentinel method is implemented complementary to WHO-recommended methods for estimating nationally representative levels of acquired HIV drug resistance.

The epidemiology of the disease is mediated by the interaction of the parasite (trypanosome) with the vectors (tsetse flies), as well as with the human and animal hosts within a particular environment. Related to these interactions, the disease is confined in spatially limited areas called “foci..., which are located
in Sub-Saharan Africa, mainly in remote rural areas. The risk of contracting HAT is, therefore, determined by the possibility of contact of a human being with an infected tsetse fly. Epidemics of HAT were described at the beginning of the 20th century; intensive activities have been set up to confront the disease, and it was under control in the 1960s, with fewer than 5,000 cases reported in the whole continent.

Avec l’essor des traitements antirétroviraux (TAR) à base de dolutégravir (DTG) pour soigner les personnes vivant avec
le VIH dans le monde, il est important d’estimer la vitesse à laquelle la résistance acquise au DTG apparaît dans les
populations sous TAR. Bien que la résistance au DT...G ne soit pas apparue dans les populations naïves aux TAR incapables
de supprimer la charge virale dans les essais cliniques, certains éléments portent à croire que la résistance au
DTG peut émerger chez les personnes suivant des schémas thérapeutiques incluant le DTG. L’OMS recommande aux
pays qui étendent les TAR incluant le DTG d’accompagner ce déploiement d’une surveillance en routine de la pharmacorésistance

A medida que el tratamiento antirretrovírico con dolutegravir se extiende a más personas que viven con el VIH en el
mundo, adquiere más importancia estimar la frecuencia con que surge la farmacorresistencia adquirida a este
antirretrovírico en las poblaciones tratadas con esquemas que lo conti...enen. Si bien no se ha detectado resistencia
al dolutegravir en los ensayos clínicos con poblaciones no tratadas antes con antirretrovíricos en las que se ha
detectado una viremia persistente pese al tratamiento, los datos indican que puede surgir en quienes toman esquemas
con dolutegravir. La OMS recomienda a los países que estén ampliando el tratamiento con dolutegravir que acompañen
su despliegue con la vigilancia sistemática de la farmacorresistencia.

The annual Joint Meeting of the Food and Agriculture Organization of the United Nations (FAO) Panel of Experts on Pesticide Residues in Food and the Environment and the World Health Organization (WHO) Core Assessment Group on Pesticide Residues (JMPR) was held in Rome, Italy, from 13 to 22 September.... The FAO panel of experts had met in preparatory sessions from 8 to 12 September. The Meeting was held in pursuance of recommendations made by previous Meetings and accepted by the governing bodies of FAO and WHO that studies should be undertaken jointly by experts to evaluate possible hazards to humans arising from the occurrence of pesticide residues in foods. During the meeting the FAO Panel of Experts was responsible for reviewing pesticide use patterns (use of good agricultural practices), data on the chemistry and composition of the pesticides and methods of analysis for pesticide residues and for estimating the maximum residue levels that might occur as a result of the use of the pesticides according to good agricultural use practices. The WHO Core Assessment Group was responsible for reviewing toxicological and related data and for estimating, where possible and appropriate, acceptable daily intakes (ADIs) and acute reference doses (ARfDs) of the pesticides for humans. This report contains information on ADIs, ARfDs, maximum residue levels, and general principles for the evaluation of pesticides. The recommendations of the Joint Meeting, including further research and information, are proposed for use by Member governments of the respective agencies and other interested parties.

This policy brief describes key HIV viral load thresholds and the available viral load testing approaches for monitoring how well antiretroviral therapy is working for people living with HIV. It provides clarification for and elaborates upon the current treatment monitoring algorithm from the Consol...idated guidelines on HIV prevention, testing, treatment, service delivery and monitoring: recommendations for a public health approach.
This information can help people living with HIV to live healthy lives, ensure that HIV is not transmitted to other people and support policy-makers in determining the optimal allocation of resources for viral load testing and communicating the results.

While there has been real progress in addressing the burden of disease in the WHO African region, the COVID-19 pandemic has highlighted the link between health, economics and security, as the region saw decades of progress threatened, including positive trends in decreasing inequality. In the Africa...n Region the momentum towards achieving the 2030 SDG disease burden reduction targets (SDG targets 3.3, 3.4 and 3B) has stalled.
The COVID-19 pandemic was also a major threat to gains made, such as the eradication of polio in the region, declared in 2020; reduced numbers of new HIV infections in 2021 compared to 2010; and passing the 2020 milestone of the End TB Strategy, with a 22% reduction in new cases compared with 2015. However, the pandemic also disrupted essential health services in 92% of countries globally, 22.7 million children missed basic immunization, there was an increase in malaria and TB, and global deaths from TB rose for the first time since 2015.

As the Americas undergo profound demographic change and there are more persons aged 65 years or older than children younger than 5 years, it is crucial to recognize that national immunization programs must be redesigned to ensure comprehensive protection for individuals across the lifespan. By adopt...ing a life course approach (LCA) to immunization, vaccination programs can be tailored to close immunity gaps at different stages of life. The life course approach foresees the establishment of multiple strategies to reduce missed opportunities for vaccination according to age group. This technical document explains the key concepts of the LCA with a focus on immunization by vaccination, as well as the underlying biological mechanisms that require the application different vaccines at different life stages according to changes to the immune system and in the epidemiological situation of a community.

Hepatitis B (HBV) infection is a major public health problem and cause of chronic liver disease.
The 2024 HBV guidelines provide updated evidence-informed recommendations on key priority topics. These include expanded and simplified treatment criteria for adults but now also for adolescents; expa...nded eligibility for antiviral prophylaxis for pregnant women to prevent mother-to-child transmission of HBV; improving HBV diagnostics through use of point-of-care HBV DNA viral load and reflex approaches to HBV DNA testing; who to test and how to test for HDV infection; and approaches to promote delivery of high-quality HBV services, including strategies to promote adherence to long-term antiviral therapy and retention in care.
The 2024 guidelines include 11 updated chapters with new recommendations and also update existing chapters without new recommendations, such as those on treatment monitoring and surveillance for liver cancer.

This is an update (third edition) of the BACPR Standards & Core Components and represents current evidence-based best practice and a pragmatic overview of the structure and function of Cardiovascular Prevention and Rehabilitation Programmes (CPRPs) in the UK. The previously described seven standards... have now been reduced to six but without sacrificing any of the key elements and with a greater emphasis placed on measurable clinical outcomes, audit and certification. Similarly, the second edition provided an overview of seven core components felt to be essential for the delivery of quality prevention and rehabilitation, and this too has been reduced to six. The interplay between cardio-protective therapies and medical risk factors is almost impossible to disentangle for the vast majority of patients and even if specific drug therapies are deployed exclusively for risk factor modulation, the indirect effect will also be cardio-protective. Thus, these have been combined into a single core component – medical risk management.

This UNAIDS 2024 report brings together new data and case studies which demonstrate that the decisions and policy choices taken by world leaders this year will decide the fate of millions of lives and whether the world’s deadliest pandemic is overcome.
Asthma is the most common non-communicable disease in children and remains one of the most common throughout the life course. The great majority of the burden of this disease is seen in low-income and middle-income countries (LMICs), which have disproportionately high asthma-related mortality relati...ve to asthma prevalence. This is particularly true for many countries in sub-Saharan Africa. Although inhaled asthma treatments (particularly those containing inhaled corticosteroids) markedly reduce asthma morbidity and mortality, a substantial proportion of the children, adolescents, and adults with asthma in LMICs do not get to benefit from these, due to poor availability and affordability. In this review, we consider the reality faced by clinicians managing asthma in the primary and secondary care in sub-Saharan Africa and suggest how we might go about making diagnosis and treatment decisions in a range of resource-constrained scenarios. We also provide recommendations for research and policy, to help bridge the gap between current practice in sub-Saharan Africa and Global Initiative for Asthma (GINA) recommended diagnostic processes and treatment for children, adolescents, and adults with asthma.

HIV Treatment - Interim Guidance
It is estimated that more than 311 000 women die of cervical
cancer each year. Of these deaths, 91% occur in low- and
middle-income countries. Demographic changes and a lack of
action mean that the number of deaths per year is projected
to reach 460 000 by 2040.
The aim of this paper is to investigate how doctors working in primary health care in Latin American address patients with common mental disorders and to investigate how stigma can affect their clinical decisions
