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.

Asthma is the most common noncommunicable disease in children, and among the most common in adults. According to the most recent estimates from the Global Asthma Network Phase I study, around one in 10 children and adults have symptoms of asthma and one in 20 school-aged children have severe asthma ...symptoms, with marked variations in prevalence and in prevalence trends between countries and regions of the world. The Global Burden of Disease Study estimated that asthma caused the loss of 21.6 million healthy years of life (disability-adjusted life years) and 461 069 deaths in 2019. Approximately 90% of the asthma burden of disease is borne by people living low and middle income countries (LMICs). Some countries report very high (up to 90%) rates of uncontrolled asthma. While the prevalence of asthma is highest in countries with a high Socio-Demographic Index (SDI), death rates from asthma are highest in countries with low and lower middle incomes.

The interim guidelines are based on what is currently known about the Coronavirus Disease 2019 (COVID-19). The National Department of Health (NDOH) and National Institute for Communicable Diseases will update these interim guidelines as needed and as additional information becomes available.

Project protocol
Introduction Ready-to-eat food sold in the street represents a global phenomenon, more common in urbanized areas, that constitutes an important dietary source in populations from low- and middle-income countries. However, research on the kind of street food offered and its composit...ion is scarce. The main objective of this study is to characterize the urban street food environment, including vending places, the food offered, its nutritional composition, food purchasing patterns and advertising.
Methods and analysis This protocol provides a framework for a stepwise, standardized characterization of the street food environment; it consists of three steps that are of increasing complexity and demand increasingly great human and technical resources. Step 1 comprises identification of street food vending sites and characterization of the products available; this stage may be complemented with an evaluation of food advertising in the streets. Step 2 comprises description of street food purchasing patterns, by direct observation. Step 3 requires collection of food samples for bromatological analysis. Different levels of data collection may be defined for each step; hereafter, these are presented as core and expanded evaluations. For the most part, data analysis involves descriptive statistics and basic spatial analysis.

J Glob Health Sci. 2020 Jun;2(1):e3. A group of enzootic and zoonotic protozoan infections, the leishmaniases constitute among the most severely neglected tropical diseases (NTDs) and are found in all continents except Oceania. Representing the most common infectious diseases, NTDs comprise an open-...ended list of some 20 parasitic, bacterial, viral, protozoan and helminthic infections. Called “diseases of the poor,” because of their characteristic prevalence in poor populations regardless of a country's income status, they infect over one billion people in over 140 countries, with about 90% of the global burden in Africa. While NTDs do not contribute significantly to global deaths, they are debilitating and remain the most common infections among the poor worldwide, preventing them from escaping poverty by impacting livelihoods such as agriculture and livestock, and affecting cognitive, developmental and education outcomes.

The overall threat posed by Omicron largely depends on four key questions: (i) how transmissible the variant is; (ii) how well vaccines and prior infection protect against infection, transmission, clinical disease and death; (iii) how virulent the variant is compared to other varian...ts; and (iv) how populations understand these dynamics, perceive risk and follow control measures, including public health and social measures (PHSM).
