Antimicrobials are medicines, including antibiotics, antivirals, antifungals, and antiparasitics, that are used to prevent and treat infections in humans, animals, and plants. Antimicrobial Resistance (AMR) arises when bacteria, viruses, fungi, and parasites no longer respond to these medicines, ren...dering them ineffective and making infections more difficult to treat. This resistance increases the risk of disease spread, severe illness, disability, and death. Although AMR is a natural phenomenon driven by genetic
changes in pathogens, it is significantly accelerated by human activities such as the misuse and overuse of antimicrobials in healthcare, agriculture, and animal husbandry.

HIV testing programmes need to ensure that all clients who test for HIV are provided with correct diagnoses. The accuracy of HIV testing is critical to prevent misdiagnosis, as the consequences of giving an incorrect test result can be serious for clients, HIV testing services, HIV programmes and pu...blic health.
With the evolution of global HIV epidemiology, HIV testing approaches must also evolve to maintain accuracy and efficiency in population-level diagnosis. Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used. As a result of changing epidemiology and declining HIV positivity in testing, WHO recommends all countries use a standard three-test strategy to ensure a PPV of at least 99%, minimizing false-positive misdiagnosis. The WHO-recommended HIV testing strategy, along with quality assurance measures such as retesting to verify a positive diagnosis prior to initiation of HIV treatment, is cost-effective as it prevents misdiagnosis and unnecessary initiation of costly lifelong treatment.
This implementation guide provides practical advice on switching to a three-test strategy and instituting other measures that can help national HIV programmes deliver high-quality, accurate HIV testing services and ensure that misdiagnosis is minimized.

In 2014, the World Heart Federation (WHF) launched
an initiative to develop a series of Roadmaps [1e6]. Their
aim is to identify potential roadblocks on the pathway to
effective prevention, detection, and management of cardiovascular disease (CVD), along with evidence-based
solutions to overcome... them. The resulting documents
provide a framework to translate strategic intent into action
on integrating epidemiology, population, and cardiovascular outcome trial data into national plans for optimal
CVD management.

The pharmacological management of asthma has changed considerably in recent decades, as it has come to be understood that it is a complex, heterogeneous disease with different phenotypes and endotypes. It is now clear that the goal of asthma treatment should be to achieve and maintain control of the... disease, as well as to minimize the risks (of exacerbations, disease instability, accelerated loss of lung function, and adverse treatment effects). That requires an approach that is personalized in terms of the pharmacological treatment, patient education, written action plan, training in correct inhaler use, and review of the inhaler technique at each office visit. A panel of 22 pulmonologists was invited to perform a critical review of recent evidence of pharmacological treatment of asthma and to prepare this set of recommendations, a treatment guide tailored to use in Brazil. The topics or questions related to the most significant changes in concepts, and consequently in the management of asthma in clinical practice, were chosen by a panel of experts. To formulate these recommendations, we asked each expert to perform a critical review of a topic or to respond to a question, on the basis of evidence in the literature. In a second phase, three experts discussed and structured all texts submitted by the others. That was followed by a third phase, in which all of the experts reviewed and discussed each recommendation. These recommendations, which are intended for physicians involved in the treatment of asthma, apply to asthma patients of all ages.

Globally, 311,000 women die of cervical cancer every year, 85 percent of them
in resource limited regions of the world. To address this grave threat to women,
the WHO made a call to action in 2018, resulting in accelerated plans to improve
cervical cancer control under the elimination threshold w...ith respect to cervical
cancer incidence. As part of WHO’s approach to cervical cancer control, availability of high quality,
affordable medical devices for HPV screening, and treatment of precancerous
lesions in low resource settings is indispensable.

A discussion paper on the scope of the problem, its drivers, and strategies for moving forward for policy, practice, and research
In many protracted emergencies, the prevalence rates of global acute malnutrition (GAM) regularly exceed the emergency threshold of > 15% of children with acute malnutri...tion (< -2 weight-for-height z-scores (WHZ) or with nutritional edema), despite ongoing humanitarian interventions. The widespread scale and long-lasting nature of “persistent GAM” means that it is a policy and programming priority.

Antibiotics have been useful in fighting infectious diseases in our country for decades, but because of the overuse and misuse of these agents, an increasing number of organisms are now resistant to them. The Philippines, like other Southeast Asian countries, has already been encountering the many c...hallenges of antimicrobial resistance (AMR) which include increasing social and economic costs and rising patient mortality. Although considered a global threat, it is already an emerging local health concern which calls for an urgent collaboration among different sectors to provide solutions addressing this growing problem.

Infectious diseases are constantly in transition. New diseases develop, known dis-eases become widespread or reemerge, and occasionally a disease is eradicated.Infectious diseases such as HIV, tuberculosis, and cholera are significant causes ofillness and death in many parts of the world. Health car...e personnel are on thefront lines, helping to protect their clients from infectious diseases and treatingthem when infections occur. During the course of their work, health care person-nel perform clinical procedures or other activities that can expose both them andtheir clients to potentially infectious microorganisms. Many of their clients aresick and thus may be more susceptible to infections or may have infections thatcan be transmitted to others. Fortunately, all staff working at health care facilities can perform simple proce-dures to minimize risk—to themselves and clients—and reduce the spread ofinfections. These practices can be integrated at minimal cost into the routineworkday at clinics and hospitals around the world. This reference booklet isspecifically designed for use at all levels of the health care system, from thelargest hospitals to the smallest dispensaries or health posts, in settings whereresources are scarce. This booklet, which was first published in 1999, has now been updated. Whilemost practices remain the same, there have been a few important changes—forexample, in recommendations related to hand hygiene and standard precautions.Nonetheless, this booklet continues to present practical recommendations forsimple and relatively low-cost procedures that can be implemented anywhere,with basic supplies and little to no high-technology equipment.

Arsenical monotherapies were previously very successful for treating human African trypanosomiasis (HAT).
Melarsoprol resistance emerged as early as the 1970s and was widespread by the late 1990s.
Melarsoprol resistance represents the only example of widespread drug resistance in HAT patients wher...e the genetic mechanism has been established.
The current goal of elimination of HAT as a public health problem by 2020 may be undermined by the emergence and spread of resistance to current or new drugs.
Insights into potential resistance mechanisms for current and new drugs will facilitate predictions of the likelihood of resistance and will also facilitate rational approaches to minimizing, monitoring, and tackling the future emergence of resistance.

It describes and analyzes the theoretical-practical incidences of misinformation, disinformation, and malinformation, including but not limited to the Information Science framework. Besides, it aims to outline an understanding of these three concepts based on 16 arrangements intercon...nected according to their intentionality.
Conclusions: We highlight that the complexity that permeates the various fields in the present situation is due to the difficulty of reaching a consensus on the semantic definition of the concepts of information, misinformation, and its disambiguations since these concepts have various properties.

The COVID-19 pandemic’s immediate costs, measured in lives lost and damaged, have been appalling and continue to rise. In addition, its effects on individuals’ livelihoods and economies around the world have been deep and are likely to be long lasting. While saving lives was the near-exclusive f...ocus during the first phase of the crisis, governments are now trying to strike a delicate balance between preventing further economic damage by reopening parts of their economies, while managing the obvious health risks of doing so.
In the international mobility and migration arenas—policy areas enormously affected by the health and economic effects of the pandemic—this reflection considers both how these fields have fared thus far and the challenges that lay ahead
