Parasites & Vectors volume 11, Article number: 264 (2018)
Dengue creates a staggering epidemiological and economic burden for endemic countries. Without a specific therapy and with a commercial vaccine that presents some problems relative to its full effectiveness, initiatives to improve vector... control strategies, early disease diagnostics and the development of vaccines and antiviral drugs are priorities. In this study, we present the probable origins of dengue in America and the trajectories of its spread. Overall, dengue diagnostics are costly, making the monitoring of dengue epidemiology more difficult and affecting physicians’ therapeutic decisions regarding dengue patients, especially in developing countries. This review also highlights some recent and important findings regarding dengue in Brazil and the Americas. We also summarize the existing DENV polymerase chain reaction (PCR) diagnostic tests to provide an improved reference since these tests are useful and accurate at discriminating DENV from other flaviviruses that co-circulate in the Americas. Additionally, these DENV PCR assays ensure virus serotyping, enabling epidemiologic monitoring.

Today there are Community-based Rehabilitation (CBR) programmes in a large number of countries. In many countries, the CBR approach is a part of the national rehabilitation services. However, there is a lack of reliable data about persons with disabilities who benefit from CBR and the kind of benefi...ts they receive. This article reviews the disability data collection systems and presents some case studies to understand the influence of operational factors on data collection in the CBR programmes. The review shows that most CBR programmes use a variable number of broad functional categories to collect information about persons with disabilities, combined occasionally with more specific diagnostic categories. This categorisation is influenced by local contexts and operational factors, including the limitations of human and material resources available for its implementation, making it difficult to have comparable CBR data. Therefore, any strategies to strengthen the data collection in CBR programmes must take these operational factors into account.

The article presents findings from the BREATHE study, which assessed the distribution of COPD-related symptoms in the Middle East and North Africa (MENA) region. The study involved a large cross-sectional survey in 11 countries, collecting data on respiratory symptoms, smoking habits, and potential ...COPD prevalence in adults aged 40 and older. Results showed that 14.3% of the surveyed population reported symptoms consistent with COPD, with variations across countries. Women reported symptoms more frequently than men, though diagnosed COPD was more common in men. The study highlighted smoking, including waterpipe use, as significant risk factors and called attention to underdiagnosed COPD in the region, emphasizing the need for increased awareness and better diagnostic practices.

Dans la plupart des pays, les services de lutte contre la tuberculose (TB) sont décentralisés jusqu’aux dispensaires
les plus périphériques et souvent au sein même des villages et des quartiers. Par contre, les services
de lutte contre le VIH/Sida sont généralement beaucoup plus centralis...és parce que la diffusion des
soins, notamment de la thérapie antirétrovirale (TARV), n’a commencé qu’assez récemment. De ce fait,
les patients qui ont besoin d’un traitement à la fois contre la tuberculose et le VIH/Sida peuvent être obligés
de se rendre dans deux établissements distincts et ainsi d’avoir à parcourir de longues distances pour
accéder aux soins. L’absence de services intégrés TB/VIH peut provoquer des retards dans le diagnostic
et le traitement, et même se traduire par un mauvais suivi des traitements, voire par des interruptions. Par
ailleurs, les patients ont à supporter la charge financière des frais de déplacement et des autres coûts indirects,
tels que de longs temps d’attente et une perte de revenu

Le cancer du sein est le cancer le plus courant dans le monde et la première cause de mortalité imputable cette maladie chez les femmes. Il touche de façon disproportionnée les pays à revenu faible et intermédiaire. L’Initiative mondiale contre le cancer du sein met tout en œuvre pour faire... reculer la mortalité due à cette maladie de 2,5 pour cent par an, ce qui, en vingt ans, pourrait sauver 2,5 millions de vies. Cet ensemble de mesures techniques fondamentales a pour objet de définir les grandes lignes d’une voie qui mènerait à des améliorations progressives et pérennes, adaptées aux besoins spécifiques des pays et reposant sur trois stratégies et objectifs clés : promotion de la santé à l’appui d’une détection précoce, diagnostic en temps voulu et prise en charge globale du cancer du sein. Le présent document propose un cadre commun associant les décideurs politiques, les parties prenantes, le milieu hospitalier, les gestionnaires de programmes et la société civile à une démarche systématique fondée sur des données probantes susceptible de faciliter le renforcement des systèmes de santé et de diminuer les inégalités touchant à la santé des femmes tout au long de leur vie.

This tool is designed to help governments, partners, and other stakeholders to estimate potential requirements for essential supplies to respond to the current pandemic of COVID-19. Although it gives users with an estimation of the number of cases, this calculator is not an epidemiological calculato...r.
The focus of this tool is to forecast essential supplies: it includes estimation of personal protective equipment, diagnostic equipment, biomedical equipment for case management, essential drugs for supportive care, and consumable medical supplies.
The COVID-19 ESFT tool is intended to be complimentary to the Health Workforce tools (Adaptt and the Workforce Estimator). Both tools use the same base clinical attack rate ranges and classify health workforce using ILO ISCO codes, but their outputs are intentionally different due to their primary focus.

Each year, ≈795 000 individuals in the United States experience a stroke, of which 87% (690 000) are ischemic and 185 000 are recurrent.1 Approximately 240 000 individuals experience a transient ischemic attack (TIA) each year.2 The risk of recurrent stroke or TIA is high but can be mitiga...ted with appropriate secondary stroke prevention. In fact, cohort studies have shown a reduction in recurrent stroke and TIA rates in recent years as secondary stroke prevention strategies have improved.3,4 A meta-analysis of randomized controlled trials (RCTs) of secondary stroke prevention therapies published from 1960 to 2009 showed a reduction in annual stroke recurrence from 8.7% in the 1960s to 5.0% in the 2000s, with the reduction driven largely by improved blood pressure (BP) control and use of antiplatelet therapy.5 The changes may have been influenced by changes in diagnostic criteria and differing sensitivities of diagnostic tests over the years.

WHO Guideline. Since 2010, countries in the meningitis belt have started to introduce a new serogroup A meningococcal conjugate vaccine conferring individual protection and herd immunity. Following the successful roll-out of this vaccine, epidemics due to Neisseria meningitidis serogroup A (NmA) are... disappearing, but other serogroups (e.g. NmW, NmX and NmC) still cause epidemics, albeit at a lower frequency and of a smaller size. Due to these changes, WHO organized the review of the evidence to provide recommendations for epidemic control, related to operational thresholds for investigation and response to outbreaks, the use of rapid diagnostic tests, antibiotic regimens in epidemics, and prophylaxis for household contacts of cases

"Explosions can produce unique patterns of injury seldom seen outside combat.
When they do occur, they have the potential to inflict multi-system life-threatening injuries
on many persons simultaneously. The injury patterns following such events are a product of
the composition and amount of the ...materials involved, the surrounding environment,
delivery method (if a bomb), the distance between the victim and the blast, and any
intervening protective barriers or environmental hazards. Because explosions are relatively
infrequent, blast-related injuries can present unique triage, diagnostic, and management
challenges to providers of emergency care. "

Young children are especially susceptible to exposure to trauma. Rates of abuse and neglect among this population are staggering. This article presents a review of relevant literature, including research findings specific to early childhood vulnerability to trauma, symptoms associated with traumatic... events, diagnostic validity of early childhood trauma, and treatments for young children. In the past, misconceptions about the mental health of young children have hindered accurate diagnosis and treatment of trauma-related mental illness. Due to the prevalence of trauma exposure in early childhood, counselors are encouraged to become familiar with ways that clients and families are impacted and methods for treatment. Implications for future research also are presented.

Myocardial infarctions are generally clinically classified into ST elevation MI (STEMI) and non-ST elevation MI (NSTEMI), based on changes in ECG. When blood flow to a part of the heart stops or the heart is injured and fails to receive enough oxygen required for its adequate functioning the conditi...on is termed as STEMI or the ‘heart-attack’ in laymen language. Patients with elevated cardiac troponin levels but negative CK-MB who were formerly diagnosed with unstable angina or minor myocardial injury are now reclassified as non-ST-segment elevation Myocardial Infarction (non-STEMI) even in the absence of diagnostic changes.

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.
