Research indicates that family reaction to the birth of a disabled child changes according to the type of disability and the child's diagnostic category. The differences are probably an indirect consequence of anticipated or actual reactions by those ...surrounding the disabled child and the family, in addition to parental reactions. Many researchers have recently mentioned the positive coping and functioning of many families with developmentally disabled children. In the past there was a tendency to emphasize issues of illness and pressures, spousal strain and maladjustment within the family, while presently they are replaced with questions concerning positive adjustment, satisfaction, acceptance, and spousal harmony. Rather than perceiving the family as a helpless victim, it is perceived as a unit that adapts by a process of structuring. Professionals must acknowledge the importance of the family, this change towards a positive attitude towards disability and that the controls decisions concerning the disabled child and the family.

Background: In Benin, little is known about the influence of both gender and
HIV-status on diagnostic patterns and treatment outcomes of Tuberculosis
(TB) patients. Objective: To assess whether differences in gender and HIV
status affect diagn...ostic patterns and treatment outcomes of TB patients. Methods:
Retrospective cohort study of patients registered in 2013 and 2014 in
the three largest TB Basic Management Units in south Benin. Results: Of 2694
registered TB patients, 1700 (63.1%) were male. Case notification rates were
higher in males compared with females (96 vs 53/100,000 inhabitants). The
male to female ratio was 1:1 in HIV positive patients, but was 2:1 among HIV
negative cases. In HIV-positive patients, there were no differences in TB types
between men and women. In HIV-negative patients, there were significantly
higher proportions of females with clinically diagnosed pulmonary TB (p =
0.04) and extrapulmonary TB (p < 0.001). Retreatment TB was 4.65 times
higher amongst males compared with females. For New bacteriologically confirmed
pulmonary TB, no differences were observed in treatment outcomes
between genders in the HIV positive group; but significantly more unfavorable
outcomes were reported among HIV negative males, with higher rates of
failure (p < 0.001) and loss-to-follow up (p = 0.02). Conclusion: The study
has shown that overall TB notification rates were higher in males than in females
in south Benin, with more females co-infected with HIV. Unfavorable outcomes were more common in HIV-negative males.

Heart failure (HF) is a global public health concern with disproportionate socioeconomic, morbidity and mortality burden on low- and middle-income countries (LMICs). This review summarises contemporary data on the demographic and clinical characteristics, aetiologies, treatment, economic burden and ...outcomes of HF in LMICs. Patients with HF in LMICs are younger than those from high-income countries (HICs) and present at advanced stages of the disease. Hypertension, ischaemic heart disease (IHD), cardiomyopathy (CMO), and rheumatic heart disease (RHD) are the leading causes of HF in LMICs. The contribution of infectious diseases to HF remains prominent in many LMICs. Most health facilities in LMICs lack adequate diagnostic tools for HF, and the use of evidence-based medical and device therapies is suboptimal. Further, HF in LMICs is associated with prolonged hospital stay and high in-hospital and one-year mortality. Finally, HF has profound economic impact on individual patients who, mostly, have no health insurance, and on societies where patients are young, comprising those who have the greatest potential to contribute to economic productivity.

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.

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.

To assess the quality of Indian clinical practice guidelines (CPG)s for the management of cardiovascular conditions, MEDLINE, Embase, Google Scholar and websites of relevant medical associations and government organisations were searched, from inception until August 2020, to identify Indian CPGs for... the management of cardiovascular disease (CVD) conditions, produced in or between 2010 and 2019. Excluded were CPGs that were not specific to India, focused on alternative systems of medicine, of non-CVD conditions (even if they included a component of CVD), and those related to the electronic devices, cardiac biomarkers, or diagnostic procedures. Quality of the each included CPG was assessed using the AGREE II tool by four reviewers in duplicate, independently. Each AGREE II domain score and overall quality score was considered low (≤40%), moderate (40.1%-59.9%), and high (≥60%). Of the 23 CPGs included, six (26%) were reported to be adapted from other CPGs. Fourteen (61%) CPGs were produced by medical associations, six (26%) by individual authors and three (13%) by government agencies. Based on the AGREE II overall quality score, two (9%) CPGs were of high quality, four (17%) and seventeen (74%) CPGs were of moderate and low quality, respectively. Except for scope and purpose, and clarity of presentation all other domains were rated low. The quality of most Indian CPGs for managing CVD conditions assessed using the AGREE II tool was moderate-to-low. Combined efforts from different stakeholders are needed to develop, disseminate and implement high-quality CPGs while identifying and addressing barriers to their uptake to optimize patient care and improve outcomes.

-rence Laboratories (NRLs) across Africa.
Africa CDC and APHF are coordinating a continental initiative to maximize the benefits of molecular approaches and pathogen genomics for more effective
outbreak preparedness, prevention, response, and for the control and elimination of endemic diseases in Africa. One of Africa CDC’s flagship initiative is the Africa
Pathogen Genomics Initiative (Africa PGI), a partnership that aims to strengthen laboratory systems and enhance genomic surveillance by equipping the continent’s
public health institutions with the tools, training, and data infrastructure.
About the Project
In 2023, 166 outbreaks and public health events were reported in Africa. This calls for a resilient laboratory systems for timely detection and reporting of current and future outbreaks. This project aims to scale up molecular diagnostic and genomic sequencing-based detection and characterization of outbreaks.
Africa CDC is working with Member States to develop guidance, diagnostic algorithm, training and capacity building to enable outbreak detection, and reporting to inform public health response.

Diagnosing asthma in children represents an important clinical challenge. There is no single gold-standard test to confirm the diagnosis. Consequently, over- and under-diagnosis of asthma is frequent in children. A task force supported by the European Respiratory Society has developed these evidence...-based clinical practice guidelines for the diagnosis of asthma in children aged 5–16 years using nine Population, Intervention, Comparator and Outcome (PICO) questions. The task force conducted systematic literature searches for all PICO questions and screened the outputs from these, including relevant full-text articles. All task force members approved the final decision for inclusion of research papers. The task force assessed the quality of the evidence using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach.
The task force then developed a diagnostic algorithm based on the critical appraisal of the PICO questions, preferences expressed by lay members and test availability. Proposed cut-offs were determined based on the best available evidence. The task force formulated recommendations using the GRADE Evidence to Decision framework.
Based on the critical appraisal of the evidence and the Evidence to Decision framework, the task force recommends spirometry, bronchodilator reversibility testing and exhaled nitric oxide fraction as first-line diagnostic tests in children under investigation for asthma. The task force recommends against diagnosing asthma in children based on clinical history alone or following a single abnormal objective test. Finally, this guideline also proposes a set of research priorities to improve asthma diagnosis in children in the future.
