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.

This paper explores access to water, sanitation, and health in pastoral communities in northern Tanzania. It argues that the concept of gender, used on its own, is not enough to understand the complexities of sanitation, hygiene, water, and health. It explores pastoralists’ views and perspectives ...on what is ‘clean’, ‘safe’, and ‘healthy’, and their need to access water and create sanitary arrangements that work for them, given the absence of state provision of modern water, sanitation, and hygiene (WASH) infrastructure. Although Tanzania is committed to enhancing its citizens’ access to WASH services, pastoral sanitation and hygiene tend to be overlooked and little attention is paid to complex ways in which access to ‘clean’ water and ‘adequate sanitation’ is structured in these communities. This paper offers an intersectional analysis of water and sanitation needs, showing how structural discrimination in the form of a lack of appropriate infrastructure, a range of sociocultural norms and values, and individual stratifiers interact to influence the sanitation and health needs of pastoralist men, women, boys, and girls.

Climate change will increase the frequency and magnitude of extreme weather events and create risks that will impact health care facilities. Health care facilities will need to assess climate chang...e risks and adopt adaptive management strategies to be resilient, but guidance tools are lacking. In this study, a toolkit was developed for health care facility officials to assess the resiliency of their facility to climate change impacts. A mixed methods approach was used to develop climate change resiliency indicators to inform the development of the toolkit. The toolkit consists of a checklist for officials who work in areas of emergency management, facilities management and health care services and supply chain management, a facilitator’s guide for administering the checklist, and a resource guidebook to inform adaptation. Six health care facilities representing three provinces in Canada piloted the checklist. Senior level officials with expertise in the aforementioned areas were invited to review the checklist, provide feedback during qualitative interviews and review the final toolkit at a stakeholder workshop. The toolkit helps health care facility officials identify gaps in climate change preparedness, direct allocation of adaptation resources and inform strategic planning to increase resiliency to climate change.

Pakistan is the world’s fourth most polluted country. Air pollution shortens the average Pakistani’s life expectancy by 3.8 years, relative to what it would be if the World Health Organization (WHO) guideline of 5 μg/m3 was met.1 Some areas of Pakistan fare much worse than average, with air pol...lution shortening lives by almost 7 years in the country’s most polluted regions, like Lahore and Peshawar.

AACAP OFFICIAL ACTION | This Practice Parameter identifies best approaches to the assessment and management of children and adolescents across all phases of a disaster. Delivered within a disaster system of care, many interventions are appropriate for implementation in the weeks and months after a d...isaster. These include psychological first aid, family outreach, psychoeducation, social support, screening, and anxiety reduction techniques. The clinician should assess and monitor risk and protective factors across all phases of a disaster. Schools are a natural site for conducting assessments and delivering services to children. Multimodal approaches using social support, psychoeducation, and cognitive behavioral techniques have the strongest evidence base. Psychopharmacologic interventions are not generally used but may be necessary as an adjunct to other interventions for children with severe reactions or coexisting psychiatric conditions

This document is written for local and international staff running nutrition programmes in emergencies, and for local, regional and national authorities and donors involved in such programmes.
The note explains why nutrition programmes need to include early childhood development (ECD) activities t...o maximize the child’s development.
It provides practical suggestions as to what simple steps are necessary to create integrated programmes in situations of famine or food insecurity and it gives examples of how such integrated programmes have been established in other situations.

Les progrès remarquables réalisés dans la lutte contre la forme à T. b. gambiense reposent sur le dépistage et le traitement curatif, une stratégie qui interrompt la transmission en réduisant le réservoir de parasites chez l’être humain. Parfois, cette
approche a été combinée avec des... activités de lutte antivectorielle. L’objet de ces lignes directrices est donc de la plus haute importance pour la poursuite des progrès en vue de l’élimination de la THA.

L'OMS a développé une définition de cas clinique de l'état post COVID-19 par la méthodologie Delphi qui comprend 12 domaines, disponible pour une utilisation dans tous les contextes. Cette première version a été élaborée par des patients, des chercheurs et d'autres personnes, représentant... toutes les Régions de l'OMS, étant entendu que la définition peut changer à mesure que de nouvelles preuves apparaissent et que notre compréhension des conséquences de la COVID-19 continue d'évoluer.
L'état post COVID-19 survient chez les personnes ayant des antécédents d'infection probable ou confirmée par le CoV-2 du SRAS, généralement 3 mois après l'apparition de symptômes qui durent au moins 2 mois et ne peuvent être expliqués par un autre diagnostic. Les symptômes courants comprennent la fatigue, l'essoufflement, le dysfonctionnement cognitif mais aussi d'autres et ont généralement un impact sur le fonctionnement quotidien. Les symptômes peuvent être d'apparition récente après le rétablissement initial d'un épisode aigu de COVID-19 ou persister depuis la maladie initiale. Les symptômes peuvent également fluctuer ou rechuter au fil du temps.

Vol 5 No 27 | ISSN 2039-2117 (online) | ISSN 2039-9340 (print) | The rate of sexual victimization of mentally retarded children is alarming and it goes unnoticed because the perpetrators could be parents, step- parents, relatives, well-respected individuals by family members, neighbours and educator...s. Drawing from labelling theory that the mentally retarded have low IQ, majority of perpetrators tend not to get arrested because of lack of evidence. Research indicates that educators struggle to identify the psychological, behavioural and physical symptoms of sexual abuse owing to their limited training. Having employed systematic review as methodology, this research study found that mentally retarded children are prone to HIV/AIDS, PTSD and feelings of helplessness owing to uninvolvement of parents, dysfunctional communities, poverty and their inability to differentiate between abuse and affection. Based on the findings, the recommendations are that: (1) extensive training for professionals, families and community members be executed to protect children with intellectual disability. Furthermore, the rights of the mentally retarded children must be respected in the court of law when reporting sexual abuse.

Around the world, nurses are working under enormous pressure providing care to sick and dying patients during the pandemic. Many are faced with increased stress, and other negative effects on their mental health. They are also faced with the possibility of infection and death from COVID-19. Before t...he pandemic there was a global shortage of nurses, but this is likely to be exacerbated by the increased demands of caring during COVID-19 as well as the usual care of non-COVID patients.

The aim of this study is to research deeply on the post-traumatic stress disorder in sexually abused children. Proving the presence of forms of the disorder in children and the their treatment mode will be in the center of the study. The methods used to conduct this study will be a literature review... on the focused issue referring to reviews of articles which focus on the defined peer group. For the purpose we have selected only articles focusing on sexually abused children treated for post-traumatic stress disorder. The results of the study reveal that all forms of abuse could bring consequences on children, even more, posttraumatic stress is the language with which the victims communicate their sorrow in the most typical mode. Sexual abuse as one of the major forms of abuse, is among the most severe which cause irreversible consequences over a category of children. In conclusion we can assume that post-traumatic stress in sexually abused children might appear through the most severe forms of psychiatric and psychological symptoms and for the recovery and rehabilitation of the child in many cases the pharmacological treatment seems as the best choice for the child.

Rev Mex Patol Clin Med Lab 2020; 67 (2): 93-112: La tuberculosis (TB) es en la actualidad la patología de tipo infeccioso que causa mayor número de muertes alrededor del mundo cada año. La percepción acerca de esta entidad ha cambiado a lo largo del tiempo, ya que se consideraba que se relaciona...ba con la pobreza y las consecuencias de la misma como desnutrición, hacinamiento y promiscuidad; sin embargo, en los últimos 40 años con la aparición de la infección del virus de la inmunodeficiencia humana (VIH) los casos comenzaron a incrementarse, además de la aparición de nuevas sepas multirresistentes a la terapéutica convencional, lo que indudablemente ha provocado la reemergencia de esta entidad así como la potencialización en su letalidad.
