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 document is based on currently available scientific evidence on treatment for drug use disorders and sets out a framework for the implementation of the Standards, in line with principles of public health care. The Standards identify major components and features of effective systems for the tre...atment of drug use disorders. They describe treatment modalities and interventions to match the needs of people at different stages and severities of drug use disorders, in a manner consistent with the treatment of any chronic disease or health condition. The Standards are aspirational, and such, national or local treatment services or systems need not attempt to meet all the standards and recommendations made in this document all at once. However over time, progressive quality improvement, with ‘evidence-based and ethical practice’ as an objective, can and should be expected to achieve better organized, more effective and ethical systems and services for people with drug use disorders.

Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or... drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.

The guideline on Drug misuse: opioid detoxification, commissioned by NICE and developed by the National Collaborating Centre for Mental Health, sets out clear, evidence-based recommendations for healthcare staff on how to work with people who misuse opioids to significantly improve their treatment a...nd care, and to deliver detoxification safely and effectively. Of the estimated 4 million people in the UK who use illicit drugs each year, approximately 50,000 misuse opioids (such as heroin, opium, morphine, codeine and methadone). Opioid misuse presents a considerable health risk and can lead to significant social problems. This NICE guideline is an important tool in helping people to overcome their drug problem.

We systematically reviewed Medline as well as the references of published review articles for relevant studies of adherence to multidrug treatment of both drug-susceptible and drug-resistant TB through February 3, 2018. We included randomized controlled trials (RCTs) as well as prospective and retro...spective cohort studies (CSs) with an internal or external control group that evaluated any adherence intervention and conducted a meta-analysis of their impact on TB treatment outcomes. Our search identified 7,729 articles, of which 129 met the inclusion criteria for quantitative analysis. Seven adherence categories were identified, including DOT offered by different providers and at various locations, reminders and tracers, incentives and enablers, patient education, digital technologies (short message services [SMSs] via mobile phones and video-observed therapy [VOT]), staff education, and combinations of these interventions.

WHO has updated its guidelines for COVID-19 therapeutics, with revised recommendations for patients with non-severe COVID-19. This is the 13th update to these guidelines.
Updated risk rates for hospital admission in patients with non-severe COVID-19
The guidance includes updated risk rates for... hospital admission in patients with non-severe COVID-19.
The current COVID-19 virus variants tend to cause less severe disease while immunity levels are higher due to vaccination, leading to lower risks of severe illness and death for most patients.
This update includes new baseline risk estimates for hospital admission in patients with non-severe COVID-19. The new ‘moderate risk’ category now includes people previously considered to be high risk including older people and/or those with chronic conditions, disabilities, and comorbidities of chronic disease. The updated risk estimates will assist healthcare professionals to identify individuals at high, moderate or low risk of hospital admission, and to tailor treatment according to WHO guidelines:
**High: **People who are immunosuppressed remain at higher risk if they contract COVID-19, with an estimated hospitalization rate of 6%.
**Moderate: **People over 65 years old, those with conditions like obesity, diabetes and/or chronic conditions including chronic obstructive pulmonary disease, kidney or liver disease, cancer, people with disabilities and those with comorbidities of chronic disease are at moderate risk, with an estimated hospitalization rate of 3%.
Low: Those who are not in the high or moderate risk categories are at low risk of hospitalization (0.5%). Most people are low risk.
Review of COVID-19 treatments for people with non-severe COVID-19
WHO continues to strongly recommend nirmatrelvir-ritonavir (also known by its brand name ‘Paxlovid’) for people at high-risk and moderate risk of hospitalization. The recommendations state that nirmatrelvir-ritonavir is considered the best choice for most eligible patients, given its therapeutic benefits, ease of administration and fewer concerns about potential harms. Nirmatrelvir-ritonavir was first recommended by WHO in April 2022.
If nirmatrelvir-ritonavir is not available to patients at high-risk of hospitalization, WHO suggests the use of molnupiravir or remdesivir instead.
WHO suggests against the use of molnupiravir and remdesivir for patients at moderate risk, judging the potential harms to outweigh the limited benefits in patients at moderate risk of hospital admission.
For people at low risk of hospitalization, WHO does not recommend any antiviral therapy. Symptoms like fever and pain can continue to be managed with analgesics like paracetamol.
WHO also recommends against use of a new antiviral (VV116) for patients, except in clinical trials.
The update also includes a strong recommendation against the use of ivermectin for patients with non-severe COVID-19. WHO continues to advise that in patients with severe or critical COVID-19, ivermectin should only be used in clinical trials.
