INTRODUCTION: The COVID-19 pandemic has disrupted health systems around the world. The objectives of this study are to estimate the overall effect of the pandemic on essential health service use and outcomes in Mexico, describe observed and predicted trends in services over 24 months, and to estimat...e the number of visits lost through December 2020.
METHODS: We used health information system data for January 2019 to December 2020 from the Mexican Institute of Social Security (IMSS), which provides health services for more than half of Mexico's population-65 million people. Our analysis includes nine indicators of service use and three outcome indicators for reproductive, maternal and child health and non-communicable disease services. We used an interrupted time series design and linear generalised estimating equation models to estimate the change in service use and outcomes from April to December 2020. Estimates were expressed using average marginal effects on the risk ratio scale.
RESULTS: The study found that across nine health services, an estimated 8.74 million patient visits were lost in Mexico. This included a decline of over two thirds for breast and cervical cancer screenings (79% and 68%, respectively), over half for sick child visits and female contraceptive services, approximately one-third for childhood vaccinations, diabetes, hypertension and antenatal care consultations, and a decline of 10% for deliveries performed at IMSS. In terms of patient outcomes, the proportion of patients with diabetes and hypertension with controlled conditions declined by 22% and 17%, respectively. Caesarean section rate did not change.
CONCLUSION: Significant disruptions in health services show that the pandemic has strained the resilience of the Mexican health system and calls for urgent efforts to resume essential services and plan for catching up on missed preventive care even as the COVID-19 crisis continues in Mexico.

The humanitarian-development-peace nexus (HDPNX) is a new way of working that offers a framework for coherent joined-up planning and implementation of shared priorities between humanitarian development and peacebuilding actors in emergency settings. To advance the HDPNx in a given country a sh...ared foundational understanding of the current situation is needed. However it can be challenging to find such a resource perpetuating poor understanding planning and operationalization. This is one of a series of country profiles that have been developed by WHO to address that need. Each profile provides an overview of health-related nexus efforts in the country and will be updated regularly.

Supportive supervision is considered critical to community health worker programme performance, but there is relatively little understanding of how it can be sustainably done at scale. Supportive supervision is a holistic concept that encompasses three key functions: management (ensuring performance...), education (promoting development) and support (responding to needs and problems). Drawing on the experiences of the ward-based outreach team (WBOT) strategy, South Africa’s national community health worker (CHW) programme, this paper explores and describes approaches to supportive supervision in policy and programme guidelines and how these are implemented in supervision practices in the North West Province, an early adopter of the WBOT strategy. Outreach teams typically consist of six CHWs plus a nurse outreach team leader (OTL).

The extensive use of natural resources threatens to exceed the carrying capacity of the Earth. The concept of a
circular economy offers an avenue to sustainable growth, good health and decent jobs, while saving the environment
and its natural resources. Further, the change from a linear economy (t...ake, make, dispose) to a circular economy (renew, remake, share) is expected to support significantly the attainment of the Sustainable Development Goals
(SDGs), particularly SDG 12 on responsible consumption and production.

Ocean plastic pollution has reached crisis level: every minute, more than an entire garbage truck of plastic makes its way into the world’s oceans—roughly 11 million metric tons annually. While plastic waste presents an immediate threat to marine wildlife and ecosystems, this global challenge al...so has implications for major industries such as fishing and tourism, impacting the livelihoods of millions of people. The drivers and impacts of ocean plastic pollution also contribute to global challenges in food security, human health, and climate change.

Las infecciones del sitio quirúrgico (ISQ) constituyen una de las Infecciones Asociadas al Cuidado de la Salud (IACS) más frecuentes que ponen en riesgo a los pacientes llevando muchas veces al fracaso del procedimiento quirúrgico. Con una incidencia mucho mayor en países de medianos y bajos ing...resos, representa un desafío de la práctica médica cotidiana que compromete la salud y la seguridad de los pacientes. La indicación de profilaxis primaria con antibióticos en relación a los procedimientos invasivos, tiene como objetivo disminuir la incidencia de infecciones con la consecuente disminución de la morbimortalidad debiendo utilizarse únicamente en aquellos procedimientos en los que hay evidencia de efectividad. Cabe destacar que la indicación inadecuada, tiene potenciales efectos adversos tales como infecciones por Clostridium difficile, emergencia de resistencia
bacteriana, reacciones adversas a drogas e incremento de los costos en salud.
La profilaxis antibiótica como complemento de una buena técnica quirúrgica, es una medida costo efectiva de prevención de las ISQ representando alrededor del 30% de la indicación de antibióticos entre los pacientes hospitalizados. Dado que en algunos estudios el uso inapropiado de antibióticos se ve reflejado en el 40 al
80% de las indicaciones médicas, desde la Comisión de Infecciones Asociadas al Cuidado de la Salud y Seguridad del Paciente de SADI hemos realizado una actualización de la evidencia disponible. Este documento es una acción complementaria al consenso “Prevención de Infección del Sitio Quirúrgico” realizado entre SADI y el Instituto Nacional de Epidemiología “J. Jara” durante el Congreso de SADI 2015.
La posibilidad de contar con una guía actualizada de profilaxis quirúrgica adaptada a nuestro medio, constituye una herramienta de uso cotidiano por parte de los profesionales del equipo quirúrgico que permite la optimización de la utilización de fármacos restringiendo así la emergencia y diseminación de la resistencia bacteriana. Sin duda esperamos que pueda ser de utilidad para el equipo de salud.

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
Buruli ulcer caused by Mycobacterium ulcerans is a neglected tropical disease characterized by extensive ulceration involving predominantly the upper and lower limbs of patients. The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is lim...ited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

The WHO estimates that 19 million children aged 15 years or younger are visually impaired. Of these, 1.4 million are irreversibly blind and need visual rehabilitation interventions for full psychological and personal development. The remainder have visual problems that could be prevented or treated.... Identifying children with visual problems early in life so that they can benefit from medical and optical interventions remains a key challenge for most child eye health programmes. Reports from various low-and middle-income countries indicate that the age of children undergoing operation for cataract is frequently too high to achieve maximum benefit.

The World Health Organization (WHO) and the global community of countries, partners, donors, technical experts, scientists and field implementation teams continue to work towards the ultimate goal of a world free of the burden of neglected tropical diseases (NTDs).
Anopheles stephensi, a highly competent vector of Plasmodium falciparum and P. vivax, is considered an efficient vector of urban malaria. Until 2011, the reported distribution of An. stephensi was confined to certain countries of South Asia and parts of the Arabian Peninsula. Since then, the vector ...has been collected in Djibouti (2012), Ethiopia (2016), Sudan (2016), Sri Lanka (2017), Somalia (2019), and most recently Nigeria (2020) and Yemen (2021). WHO considers the spread of An. stephensi to be a major potential threat to malaria control and elimination in Africa and southern Asia and has recently launched an initiative against the spread of this vector in Africa.
