El desarrollo de inmunidad a un patógeno por infección natural es un proceso de varias etapas que suele producirse a lo largo de una o dos semanas. El organismo responde a una infección vírica de forma inmediata a través de una respuesta innata no específ...ica, en la que los macrófagos, los neutrófilos y las células dendríticas frenan el avance del virus y pueden incluso evitar que este provoque síntomas. A esta respuesta no específica le sigue una respuesta adaptativa en la que el organismo genera anticuerpos que se unen específicamente al virus. Estos anticuerpos son las proteínas denominadas inmunoglobulinas. El organismo también genera linfocitos T que reconocen y eliminan las células infectadas por el virus: es lo que se conoce como inmunidad celular. Esta respuesta adaptativa combinada puede eliminar el virus del organismo y, si la respuesta es suficientemente intensa, puede evitar el agravamiento de la enfermedad o la reinfección por el mismo virus. Este proceso se mide a menudo a través de la presencia de anticuerpos en la sangre.

Un comité OMS d’experts sur la trypanosomiase humaine africaine (THA) : lutte et surveillance, s’est réuni à Genève (Suisse), du 22 au 26 avril 2013. Le Dr H. Nakatani, sous-directeur général pour le VIH/SIDA, la tuberculose, le paludisme et les maladies tropicales négligées, a ouvert la... réunion au nom du Dr M. Chan, directeur-général de l’OMS.
La THA est une maladie qui afflige les populations rurales de l’Afrique, là où prolifère la mouche tsé-tsé (ou glossine), vecteur des trypanosomes qui en sont la cause. On distingue deux formes de THA : la forme à T. b. gambiense ou forme gambienne, endémique en Afrique de l’Ouest et en Afrique centrale et qui
représente actuellement 95 % des cas, et la forme à T. b. rhodesiense ou forme rhodésienne, endémique en Afrique de l’Est et en Afrique australe, à laquelle sont dus les 5 % restants.

It is widely understood that the food insecurity crisis in the Sahel and the Horn of Africa is one of the world’s fastest growing and most neglected crises. It lacks sufficient global focus, resources and urgency. As in so many crises, women and girls are disproportionately affected and shoulder t...he consequences of protracted neglect, with unconscionable impacts on their safety, life chances and agency.
Gaining a holistic view of the gendered drivers, risks and impacts of food insecurity in the Sahel and the Horn of Africa is difficult. This is due to a lack of data and prioritization, and the large geographical and socioeconomic terrain covered by both regions. However, what we do know about this crisis is more than enough to urgently address the needs of women and girls.
An OCHA discussion paper on this topic (which will be published imminently, and from which this policy brief is drawn) found that there is:
A strong risk of profound regression in gender equality gains made to date in the countries of concern, including on education, sexual and reproductive health, and the economic independence of women and girls (with knock-on effects on broader humanitarian and development outcomes).
An increasing challenge to reverse what must be recognized as a protracted and growing gender-based violence (GBV) emergency in the Sahel and the Horn of Africa.
The food insecurity crisis in the Sahel and the Horn of Africa is protracted, multidimensional and highly gendered, with spiralling impacts on gender equality and food security outcomes. It is driven by interwoven and overlapping factors, including climate change, political instability, conflict, socioeconomic conditions, migration and displacement and, more recently, COVID-19 and the war in Ukraine. Interlinked with these factors are gendered structural drivers of food insecurity, including deeply entrenched gender inequalities and harmful social norms. Gendered risks and impacts of food insecurity include alarming limitations on access to education, sexual and reproductive health rights, women’s agency and participation, and dramatic increases in different existing forms of GBV and the emergence of new ones. Recognition of such gendered dimensions of food insecurity and of the need for a multisectoral approach in the response is key to addressing the crisis, along-side sustained commitment and adequate allocation of resources. This policy brief draws out key findings from the OCHA discussion paper on this topic, which includes a desk review of studies, assessments and reports, and interviews with local women’s organizations on the front lines of the food insecurity crisis in communities across both regions.
Below are the most pressing gendered drivers, risks and impacts of food insecurity (not in order of priority), as well as key gaps in the current humanitarian response to food insecurity, and recommendations to take forward.

La pratique infirmière avancée (PIA), telle qu’évoquée dans le présent document, se réfère aux services et
aux interventions de santé renforcés et étendus, assurés par des infirmières qui, grâce à des compétences avancées, influent sur les résultats des soins de santé cliniques ...et dispensent des services de santé directs à la personne, aux familles et aux collectivités (CNA, 2019; Hamric et Tracy, 2019). Une infirmière de pratique avancée (IPA) a acquis, grâce à une formation complémentaire, une base de connaissances spécialisées, des capacités perfectionnées en matière de prise de décision et des compétences cliniques pour une pratique infirmière plus étendue, dont les caractéristiques dépendent du contexte dans lequel elle est accréditée
à exercer ses fonctions (CII, 2008a). L’infirmière clinicienne spécialisée (ICS) et l’infirmière praticienne (IP)
sont les deux catégories d’IPA les plus généralement

BACKGROUND. Asthma is a heterogeneous condition characterised by chronic inflammation and variable expiratory airflow limitation, as well as airway reversibility. The burden of asthma in children is increasing in low- and middle-income countries and remains under-recognised and poorly managed.
OBJE...CTIVES. To quantify the burden of asthma in the South African (SA) population and identify the risk factors associated with disease severity in the local context.
METHODS. The SA Childhood Asthma Working Group (SACAWG) convened in January 2017 with task groups, each headed by a section leader, constituting the editorial committee on assessment of asthma epidemiology, diagnosis, control, treatments, novel treatments and self-management plans. The epidemiology task group reviewed the available scientific literature and assigned evidence according to the Grades of Recommendation Assessment, Development and Evaluation (GRADE) system.
CONCLUSIONS. Asthma in children remains a common condition, which has shown an increasing prevalence in urban and rural populations of SA. Of concern is that almost half of children in urban communities experience severe asthma symptoms, and many asthmatics lack a formal diagnosis and thus access to treatment. Exposure to tobacco smoke and living in highly polluted areas increase the severity of wheezing in young children.

Mientras los países se esfuerzan por avanzar hacia los Objetivos de Desarrollo Sostenible (ODS) y lograr la cobertura sanitaria universal, las desigualdades sanitarias provocadas por la discriminación racial y los factores interrelacionados siguen estando omnipresentes. Las desigualdades que sufre...n los pueblos indígenas, los afrodescendientes, los romaníes y otras minorías étnicas son preocupantes a nivel mundial; son injustas, prevenibles y remediables
Los propios sistemas de salud son determinantes importantes de la salud y la equidad sanitaria. Pueden perpetuar las desigualdades sanitarias al reflejar el racismo estructural y las prácticas discriminatorias de la sociedad en general. En este sentido, el racismo sistémico (por ejemplo, relacionado con la ubicación de los servicios o los requisitos para acceder a ellos), los prejuicios implícitos, la práctica clínica mal informada o la discriminación por parte de los profesionales de la salud contribuyen a las desigualdades sanitarias. Ahora bien, los sistemas de salud también pueden convertirse en una de las principales fuerzas para combatir las desigualdades a las que se enfrentan las poblaciones que sufren discriminación racial.
La atención primaria de salud (APS) representa la estrategia esencial que permite reorientar los sistemas de salud y las sociedades para que sean más saludables, equitativos, eficaces y sostenibles. En 2018, al cumplirse el 40.º aniversario de la Declaración de Alma-Ata, la Organización Mundial de la Salud (OMS) y el Fondo de las Naciones Unidas para la Infancia (UNICEF) renovaron el énfasis en la atención primaria de salud con su estrategia sobre la atención primaria de salud en el siglo XXI.
La OMS ha señalado 14 mecanismos estratégicos y operacionales con los que los responsables políticos pueden reforzar la atención primaria de salud. Cada mecanismo dispone de múltiples puntos de partida posibles para emprender acciones específicas dirigidas a combatir la discriminación racial, fomentar la atención de salud intercultural y reducir las desigualdades sanitarias que sufren los pueblos indígenas, los afrodescendientes, los romaníes y otras minorías étnicas

Q7. SCOPING QUESTION: In adults with moderate-severe depressive disorder, what is the effectiveness and safety of antidepressant medication (ADM) in comparison with psychological treatment?
The WHO mhGAP programme’s existing guidelines recommend that either structured brief psychological treatm...ents (e.g., interpersonal psychotherapy or cognitive behavioural therapy, including behavioural activation) or antidepressant medication (e.g., SSRIsi and tricyclic antidepressants) be considered in adults with moderate-severe depression. Health care workers need to know whether these treatments have different effects, including side-effects, in treating depressive disorder in the short and long term, in order to improve clinical decision-making.

The meeting addressed the last key area, that is, determining the best method or combination of diagnostic methods for a control programme for S. stercoralis infections in humans.
Dr Montresor’s presentation highlighted that while there is currently no “gold standard” for the... diagnosis of S. stercoralis, there is a felt urgency to optimize diagnostic regimens that are currently available, and in the context of population-based testing (as opposed to individual focused diagnostics in clinical settings).
In other words, the diagnostic test(s) should have good accuracy, but we should remember that in public health we do not aim at individual diagnosis: rather, we need a tool that should help to estimate the prevalence in a population.

Chagas disease caused by Trypanosoma cruzi is a public health issue in Latin America. This highly diverse parasite is divided into at least seven discrete typing units (DTUs) TcI-TcVI and Tcbat. Some DTUs have been associated with geographical distribution in epidemiological scenarios and clinical m...anifestations, but these aspects remain poorly understood. Many studies have focused on studying the parasite and its vectors/hosts, using a wide variety of genetic markers and methods. Here, we performed a systematic review of the literature for the last 20 years to present an update of DTUs distribution in the Americas, collecting ecoepidemiological information. We found that the DTUs are widespread across the continent and that there is a whole gamma of genetic markers used for the identification and genotyping of the parasite. The data obtained in this descriptor could improve the molecular epidemiology studies of Chagas disease in endemic regions.

2nd edition. Children with TB comprise about 10-12% of the total TB cases diagnosed in the country. This burden is likely to be higher given the challenges in diagnosing TB in children. The symptoms of TB in children mimic those of other childhood diseases. Children do not readily expectorate and th...ey have pauci-bacillary TB hence some will be missed using bacteriological tests. The government has however introduced GeneXpert molecular testing that is more sensitive than microscopy in detecting TB. Health care workers therefore need a reference guide to obtaining sputum from children for testing. Treatment of TB in children has been reviewed and now includes Ethambutol. There are now improved paediatric friendly TB medicines for treatment of TB in children and health care workers need a reference guide to enable them accurately dispense the TB medicine to children. Malnutrition is a common predisposing factor for TB in children. On the other hand, TB predisposes children to malnutrition or worsens an existing state of malnutrition. Nutrition care and support forms an integral part of treatment for a child with TB disease.
