High levels of storage iron may increase malaria susceptibility. This risk has not been investigated in semi-immune adolescents. We investigated whether baseline iron status of nonpregnant adolescent girls living in a high malaria transmission area in Burkina Faso affected malaria risk during the fo...llowing rainy season. For this prospective study, we analysed data from an interim safety survey, conducted six months into a randomised iron supplementation trial. We used logistic regression to model the risk of P. falciparum infection prevalence by microscopy, the pre-specified interim safety outcome, in relation to iron status, nutritional indicators and menarche assessed at recruitment.

For COVID-19, as for many infectious diseases, the true level of transmission is frequently underestimated because a substantial proportion of people with the infection are undetected either because they are asymptomatic or have only mild symptoms and thus typically fail to present at healthcare fac...ilities. There may also be neglected or under-served segments of the population who are less likely to access healthcare or testing. Under-detection of cases may be exacerbated during an epidemic, when testing capacity may be limited and restricted to people with severe cases and priority risk groups (such as frontline healthcare workers, elderly people and people with comorbidities). Cases may also be misdiagnosed and attributed to other diseases with similar clinical presentation, such as influenza.
Differences in mortality between groups of people and countries are important proxy indicators of relative risk of death that guide policy decisions regarding scarce medical resource allocation during the ongoing COVID-19 pandemic. This document is intended to help countries estimate CFR and, if possible, IFR, as appropriately and accurately as possible, while accounting for possible biases in their estimation

June 2021. Shock-responsive social protection (SRSP) operates in contexts where rapid on-set disasters mean needs for assistance are acute and urgent. Monitoring and identifying problems in programme design and delivery are therefore critical. However, there is limited existing guidance on how to mo...nitor shockresponsive social protection in these contexts.
This Brief aims to help fill this gap. It does not provide a blueprint for developing monitoring indicators, but it presents a guiding framework with key questions and key issues to consider when monitoring SRSP to understand how the intervention contributes to broader crisis response.

Noncommunicable diseases (NCDs) are responsible for 81% of all deaths in the region of the Americas, of which 34% befall prematurely in people between 30- 69 years old. The burden of theses diseases and their common risk factors jeopardize the health systems to provide adequate management, as well a...s to implement customized policies and interventions. The PAHO/WHO STEPwise approach to NCD risk factor surveillance (STEPS) is a simple, sequential, standardized method for collecting, analyzing, and disseminating data on key NCD risk factors in countries in adults from 18 to 69 years old. This survey covers key modifiable risk factors: tobacco use, alcohol use, physical inactivity, and unhealthy diet, as well as key biological risk factors: overweight and obesity, raised blood pressure, raised blood glucose, and abnormal blood lipids. STEPS is a household survey that gathers information on the risk factors through a face-to-face interview (step 1), simple physical measurements (step 2), and collection of urine and blood samples for biochemical analysis (step 3). Every step has a core set of questions, measurements, and expanded sets depending on the countries' needs and interests. It also has optional modules. Implementing STEPS allows the comparability of data within and between countries due to its standardized data collection. It also helps health services plan public health priorities and monitors and evaluates population-wide interventions. It is designed to help countries build and strengthen their capacity to conduct surveillance. STEPS captures 11 of the 25 indicators outlined in the NCD Global Monitoring Framework relating to 7 of the nine global targets.

This report investigates the impact of potential misclassification of samples on HIV prevalence estimates for 23 surveys conducted from 2010-2014. In addition to visual inspection of laboratory results, we examined how accounting for potential misclassification of HIV status through Bayesian latent ...class models affected the prevalence estimates. Two types of Bayesian models were specified: a model that only uses the individual dichotomous test results and a continuous model that uses the quantitative information of the EIA (i.e., the signal-to-cutoff values). Overall, we found that adjusted prevalence estimates matched the surveys’ original results, with overlapping uncertainty intervals. This suggested that misclassification of HIV status should not affect the prevalence estimates in most surveys. However, our analyses suggested that two surveys may be problematic. The prevalence could have been overestimated in the Uganda AIDS Indicator Survey 2011 and the Zambia Demographic and Health Survey 2013-14, although the magnitude of overestimation remains difficult to ascertain. Interpreting results from the Uganda survey is difficult because of the lack of internal quality control and potential violation of the multivariate normality assumption of the continuous Bayesian latent class model. In conclusion, despite the limitations of our latent class models, our analyses suggest that prevalence estimates from most of the surveys reviewed are not affected by sample misclassification.

The Global Burden of Disease (GBD) study, a collaborative endeavour of the World
Health Organization (WHO), the World Bank and the Harvard School of Public Health,
drew the attention of the international health community to the burden of neurological
disorders and many other chronic conditions. T...his study found that the burden of neurological
disorders was seriously underestimated by traditional epidemiological and health
statistical methods that take into account only mortality rates but not disability rates. The
GBD study showed that over the years the global health impact of neurological disorders
had been underestimated.

Abstract
Introduction: Road traffic accidents (RTAs) are a major public health issue
in developing countries, where roads tend to be built haphazardly and accidents
take a heavy toll on victims—including leaving them disabled. This
study seeks ...to identify those factors that cause RTA victims to become disabled
as a result of their injuries. Methods: This retrospective community-
based study looked at RTA victims treated in five public and faith-based
hospitals in Benin. Disability was evaluated using the Washington Group on
Disabilities Statistics questionnaire. The independent variables were related to
the victim’s socio-demographic traits, the circumstances of the accident, and
post-crash response mechanisms. The proportions were compared using the
chi-squared test, with a threshold of 5%. Results: The prevalence of disability
among road traffic accident victims is 9.59% (CI 95%: 6.86% - 13.20%). The
occurrence of disability is associated with age (p = 0.002), occupational group
(p = 0.0077), the mode of transport used to transfer the victim (p < 0.001)
and the location of the injuries (p = 0.0035). The study also found that people
fail to make sufficient use of post-crash response mechanisms. Conclusion:
Public policy-makers should therefore focus on stepping up interventions to
get more people using both protective equipment and post-crash response services.

An Economist Intelligence Unit briefing paper | The Economist Intelligence Unit (EIU) undertook a study aimed at assessing the degree of commitment of 15 countries within the AsiaPacific region to integrating those with mental illness into their communities. The research was commissioned and funded... by Janssen Asia Pacific, a division of Johnson & Johnson Pte. Ltd. This report focuses on the results of this benchmarking study, called the Asia-Pacific Mental Health Integration Index. Drawing on lessons from the EIU’s 2014 European Mental Health Integration Index, this edition index compares the level of effort in each of the countries on indicators associated with integrating individuals suffering from mental illness into society. Data for the Index was collected between March and May 2016. The set of 18 indicators were grouped into four categories.

Children malnutrition eradication in developing countries is a real challenge, especially among
vulnerable population. There are so many effort towards women (who are the main care providers)
socio-economic situation in order to improve their children nutrition. This article aims to identify the
...impact of mothers’ activities on child nutrition and care. Interviews were used to collect data from
mothers of children less than 5 years old. Pearson correlation test and regression models were
performed to highlight relation and to identify the main factors that affect child nutrition and care. The
nutritional statuses of children show a high prevalence of underweight (38.46%), emaciation (25.17%)
and stunting (23.77%). Statistic results show that a child whose mother has food processing as main
activity has 2,322 more times to not suffer from emaciation malnutrition compared to a child whose
mother has trade as main activity. A child whose mother has high revenue has 1.463 more times to
not be suffering from stunting malnutrition compared to a child whose mother has lower revenue. A
child whose father has fishing as main activity has 8,4 more chance to not be suffering from stunting
malnutrition compared to a child whose father has another activity as main activity. A child whose
father is present in the household has 8.11 more chance to not suffer from stunting malnutrition
compared to a child whose father is absent. A child from mother who has food processing as main
activity is 2,464 more times preserved from fever compared to a child from mother whose main activity
is trade. Moreover child position, child feeding with porridge, child nursing are correlated with mother
activity. This situation is justified by the fact that mother need money to improve child nutrition and
health but they are also confronted to the fact that those activity that provide significant money are
sometime time consuming and not permit to take care of children in term of feeding practices, hygiene
control etc. Therefore it is important that intervention towards women take in consideration those
factors (money and time) but also the family in the whole.

Maternal mortality has fallen significantly in recent years, especially in countries that have emphasized the prevention of its main causes, such as hemorrhagic and infectious complications and hypertension , including in the Region of the Americas. In its final report on the Plan of Action to Accel...erate the Reduction of Maternal Mortality and Severe Maternal Morbidity, the Pan American Health Organization (PAHO) reported a continuing downward trend in maternal mortality, with an 18.1% reduction in the maternal morbidity ratio during the period 2010-2015 . From a pathophysiological perspective, death events are a common end result of a wide spectrum of complications leading to multi-organ dysfunction. However, there is a group of women in this situation who survive, despite the seriousness of their condition. This high number of patients––who were in serious condition
but did not die––reflects the actual health conditions in an institution or a country. For this reason, there is a need to create indicators to estimate morbidity in women due to diseases and incidents that occur during pregnancy, childbirth, and the puerperium. To this end, we propose conducting epidemiological surveillance of an indicator that includes women who survived after presenting a potentially fatal complication during pregnancy, childbirth, or the puerperium, reflecting quality medical attention and care (5, 6). This indicator
is maternal near-miss (MNM), which refers to extremely severe maternal morbidity––cases of a severity that
brings women very close to the death event. After adjusting the definition to a specific population and time,
MNM is defined as a case in which a woman nearly died, but survived a complication that occurred during
pregnancy, childbirth, or within 42 days of termination of pregnancy

Asia remained the world’s most disaster-hit region from weather, climate and water-related hazards in 2023. Floods and storms caused the highest number of reported casualties and economic losses, whilst the impact of heatwaves became more severe, according to a new report from the World Meteorolog...ical Organization (WMO).
The State of the Climate in Asia 2023 report highlighted the accelerating rate of key climate change indicators such as surface temperature, glacier retreat and sea level rise, which will have major repercussions for societies, economies and ecosystems in the region.
In 2023, sea-surface temperatures in the north-west Pacific Ocean were the highest on record. Even the Arctic Ocean suffered a marine heatwave.
Asia is warming faster than the global average. The warming trend has nearly doubled since the 1961–1990 period.
