Testing and diagnosis of hepatitis B (HBV) and C (HCV) infection is the gateway for access to both prevention and treatment services, and is a crucial component of an effective response to the hepatitis epidemic. Early identification of persons with chronic HBV or HCV infection enables them to recei...ve the necessary care and treatment to prevent or delay progression of liver disease. Testing also provides an opportunity to link people to interventions to reduce transmission, through counselling on risk behaviours and provision of prevention commodities (such as sterile needles and syringes) and hepatitis B vaccination.

Several diagnostic criteria of Post-traumatic Stress Disorder (PTSD) are remarkably similar to symptoms reported by individuals with depression, particularly as they manifest as cognitive processing deficits in children. Because of this overlap in profile and the high rate of comorbidity of PTSD and... depression (48% to 69%), pinpointing similarities/differences in cognitive processes related to each of these disorders is essential to accurate diagnosis. This study aims to examine cognitive performance profiles of 23 children who have been victims of PTSD and to compare their results with 23 children with depression and 24 controls.

Progress in diagnosis: Akey in overcoming the MDR-TB crisis.
The expanse-TV project progress and impact brief.
This diagnostic and treatment manual is designed for use by medical professionals involved in cura-
tive care at the dispensary and hospital levels. We have tried to respond in the simplest and most
practical way possible to the questions and problems faced by field medical staff..., using the accumu-
lated field experience of Médecins Sans Frontières, the recommendations of reference organizations
such as the World Health Organization (WHO) and specialized works in each field.

BMJ has created a free resource on SARS-CoV-2 and covid-19 to inform diagnosis and treatment, and to promote the wellbeing and safety of staff and patients during this extremely stressful and challenging period.
BMJ’s dedicated covid-19 hub not only draws on the latest peer reviewed research, n...ews and opinion from The BMJ and BMJ’s 70 + specialist journals. It also provides online CPD from BMJ Learning and guidance on the evidence-based management of covid-19 from BMJ Best Practice.
The content is updated daily so that healthcare professionals on the frontline of care can readily keep abreast of the latest developments in thinking and practice

FIND conducted independent evaluations at the University Hospitals of Geneva (HUG), to verify the limit of detection (LOD) and the clinical performance (as reported by the manufacturers) of the following molecular test kits. The LOD analysis was performed using cultured viral stocks from a clinical ...isolate from Switzerland, and quantified using an E gene standard. The clinical performance analysis was conducted on extracted samples from individuals suspected to have COVID-19 that were tested using an in-house PCR protocol that was optimized based on the Tib Molbiol assay.

The speed of developing diagnostics for SARS-CoV-2, the causative agent of coronavirus disease 2019 (COVID-19), has been quite remarkable. Diagnostics have focused on nucleic acid amplification testing (NAAT) to identify infected individuals in acute-phase disease for timely implementation of mitiga...tion strategies and case management. More and more immunodiagnostics, mostly rapid diagnostic tests, are being made available as an alternative to NAATs. This type of test can be used out-of-laboratory conditions at large scale.

The portable diagnostic imaging technology covered by this document will serve not only the pressing demands for tuberculosis screening and triage but also other diseases. Therefore, the requirements, accessories, hardware and software packages listed in the following specifications are described in... detail in order to serve also other pathologies and conditions, like trauma and pneumonia.
Through the definition of "minimum technical requirements", this document is recommended to support decision-making regarding the selection, incorporation, allocation and use of portable X-ray systems and is intended for health care providers, managers of imaging departments, procurement and regulatory agencies, policymakers and planning officers in ministries of health, as well as biomedical engineering professionals, medical physicists, the private health sector, medical device industry and intergovernmental and international agencies.

To meet the need for laboratory diagnosis to be integrated in community care, the new 2022 Update describes point-of-care tests that can be performed both in district laboratories and peripheral healthcare facilities by non-specialist staff. Also included are recently developed self-tests.
For the molecular diagnosis of Chagas disease by real-time PCR (polymerase chain reaction), optimization of diagnostic accuracy is desirable. The detection limit of real-time PCR assays for the diagnosis of Trypanosoma cruzi in human serum is affected by various influences including the choice of th...e nucleic acid extraction assay. In this study, three nucleic acid extraction assays were compared regarding their influence on the sensitivity of a T. cruzi-specific real-time PCR with 62 reference sera containing T. cruzi target DNA (deoxyribonucleotide acid). More than 95% of the positive sera were correctly identified after all three nucleic acid extraction strategies with a detection rate ranging from 96.8% (60/62) for the worst assay to 100% (62/62) for the best one. A matched pairs analysis for the comparison of the cycle threshold (Ct) values obtained with the 59 reference samples with positive real-time PCR results after all three nucleic acid extraction schemes indicated differences in a range of about 3 Ct steps. Summarized, all three compared nucleic acid extraction schemes were basically suitable for T. cruzi-specific PCR from serum with some minor differences. However, in the case of low quantities of circulating parasite DNA in the serum of a patient with Chagas disease, even minor effects can make a difference in the individual diagnosis.

Under-diagnosis of asthma in ‘under-fives’ may be alleviated by improved inquiry into disease history. We assessed a questionnaire-based screening tool for asthma among 614 ‘under-fives’ with severe respiratory illness in Uganda. The questionnaire responses were compared to post hoc consensu...s diagnoses by three pediatricians who were guided by study definitions that were based on medical history, physical examination findings, laboratory and radiological tests, and response to bronchodilators. Children with asthma or bronchiolitis were categorized as “asthma syndrome”. Using this approach, 253 (41.2%) had asthma syndrome. History of and present breathing difficulties and present cough and wheezing was the best performing combination of four questionnaire items [sensitivity 80.8% (95% CI 77.6–84.0); specificity 84.7% (95% CI 81.8–87.6)]. The screening tool for asthma syndrome in ‘under-fives’ may provide a simple, cheap and quick method of identifying children with possible asthma. The validity and reliability of this tool in primary care settings should be tested.
