Long-term exposure of humans to air pollution enhances the risk of cardiovascular and respiratory diseases. A novel Global Exposure Mortality Model (GEMM) has been derived from many cohort studies, providing much-improved coverage of the exposure to fine particulate matter (PM2.5). We applied the GE...MM to assess excess mortality attributable to ambient air pollution on a global scale and compare to other risk factors.
Methods and results
We used a data-informed atmospheric model to calculate worldwide exposure to PM2.5 and ozone pollution, which was combined with the GEMM to estimate disease-specific excess mortality and loss of life expectancy (LLE) in 2015. Using this model, we investigated the effects of different pollution sources, distinguishing between natural (wildfires, aeolian dust) and anthropogenic emissions, including fossil fuel use. Global excess mortality from all ambient air pollution is estimated at 8.8 (7.11–10.41) million/year, with an LLE of 2.9 (2.3–3.5) years, being a factor of two higher than earlier estimates, and exceeding that of tobacco smoking. The global mean mortality rate of about 120 per 100 000 people/year is much exceeded in East Asia (196 per 100 000/year) and Europe (133 per 100 000/year). Without fossil fuel emissions, the global mean life expectancy would increase by 1.1 (0.9–1.2) years and 1.7 (1.4–2.0) years by removing all potentially controllable anthropogenic emissions. Because aeolian dust and wildfire emission control is impracticable, significant LLE is unavoidable.
Conclusion
Ambient air pollution is one of the main global health risks, causing significant excess mortality and LLE, especially through cardiovascular diseases. It causes an LLE that rivals that of tobacco smoking. The global mean LLE from air pollution strongly exceeds that by violence (all forms together), i.e. by an order of magnitude (LLE being 2.9 and 0.3 years, respectively).

This study investigated occupational risk factors and exposure–response relationships for airway disease among health workers (HWs) exposed to cleaning agents in two tertiary hospitals in South Africa and Tanzania.
Previous studies have demonstrated an association between asthma or respiratory... symptoms and exposure to broad categories of cleaning-related exposures in healthcare settings. However, few studies have identified the specific cleaning agents responsible for asthma and other health outcomes. Products used for medical instrument cleaning and disinfection such as glutaraldehyde, orthophthalaldehyde (OPA) and quaternary ammonium compounds (QACs) have been implicated in the causation and exacerbation of work-related asthma (WRA) and upper airway outcomes such as rhinitis.

The article "Economic Burden of Chronic Obstructive Pulmonary Disease (COPD): A Systematic Literature Review" examines the financial impact associated with moderate-to-very severe COPD. The review analyzes studies published between 2006 and 2016 that discuss healthcare resource utilization (HRU), di...rect costs, and indirect costs related to COPD, with a focus on Europe and North America. It highlights that direct costs, including hospitalizations and medical treatments, increase with the severity of COPD and the frequency of exacerbations. Multivariate analyses identify key factors driving these costs, such as comorbidities and prior treatment history. The findings underscore the significant economic burden of COPD on healthcare systems and emphasize the need for improved management strategies to reduce costs and optimize patient care.

The increasing prevalence of childhood asthma in the developed world is a cause for concern. A so-called Western lifestyle has been the factor most commonly cited to explain this worrying increase in asthma prevalence. Early studies in a limited number of African countries showed a very low rural pr...evalence of childhood asthma, especially where children lived according to a traditional lifestyle. These same studies showed that asthma was not uncommon in urbanized African children. There has been an
increasing tendency over the past 20 years for those in rural communities to move to the large urban centers. This article analyses the urban-rural differences and factors that influence the development of asthma in susceptible children.

Cystic fibrosis (CF) was earlier thought to be a disease prevalent in the West among Caucasians. However, quite a number of recent studies have uncovered CF cases outside of this region, and reported hundreds of unique and novel variant forms of CFTR. Here, we discuss the evidence of CF in parts of... the world earlier considered to be rare; Africa, and Asia. This review also highlighted the CFTR mutation variations and new mutations discovered in these regions. This discovery implies that the CF data from these regions were earlier underestimated. The inadequate awareness of the disease in these regions might have contributed towards the poor diagnostic facilities, under-diagnosis or/and under-reporting, and the lack of CF associated health policies. Overall, these regions have a high rate of infant, childhood and early adulthood mortality due to CF. Therefore, there is a need for a thorough investigation of CF prevalence and to identify unique and novel variant mutations within these regions in order to formulate intervention plans, create awareness, develop mutation specific screening kits and therapies to keep CF mortality at bay.

Fortbildung | VNR 2760602016064370005 | Hessisches Ärzteblatt 5/2016 | Die weltweit zu beobachtende Flucht von Menschen vor Krieg, Gewalt, Verfolgung und Hunger stellt auch für die medizinischen Versorgungssysteme in Deutschland eine große Herausforderung dar. Neben der Versorgung somatischer Kra...nkheiten kommt der Diagnostik und Therapie psychischer Erkrankungen eine hohe Bedeutung zu. In einer in einer bayrischen zentralen Aufnahmeeinrichtung für Flüchtlinge durchgeführten Studie wurden bei 63,6 Prozent der Flüchtlinge eine oder mehrere psychiatrische Diagnosen gestellt, wobei die Posttraumatische Belastungsstörung (PTBS) mit 32,2 Prozent am häufigsten vorkam. Die Angaben zur Prävalenz der PTBS in weniger belasteten Stichproben haben eine weite Bandbreite, die durch unterschiedliche Studiendesigns und durch unterschiedliche diagnostische Kriterien in der ICD 10 und dem DSM 5 bedingt sind. In den USA findet sich in der Allgemeinbevölkerung eine hochgerechnete Lebenszeitprävalenzrate von etwa 8 Prozent. In Europa liegen die Schätzungen mit 0,5–1 Prozent deutlich niedriger. Für Deutschland werden 1-Monatsprävalenzraten von 1–3 Prozent berichtet.

n Deutschland leben zurzeit etwa 22 Millionen Menschen mit Migrationshintergrund, davon sind über 2,23 Millionen älter als 65 Jahre. Eine Studie des Robert Koch-Instituts (2008) kam zu dem Ergebnis, dass Migrantinnen und Migranten ab 55 Jahren höhere Gesundheitsrisiken aufweisen als vergleichbare... Gruppen aus der Aufnahmegesellschaft. Dies liegt vor allem daran, dass sie ein höheres Armutsrisiko und einen geringeren sozialen Status haben als andere ältere Menschen.

The intended purpose of this compendium is to provide program managers, organizations, and policy makers with a menu of indicators to better “know their HIV epidemic/know their response” from a gender perspective. The indicators in the compendium are all either part of existing indicators used i...n studies or by countries or have been adapted from existing indicators to address the intersection of gender and HIV. The indicators can be measured through existing data collection and information systems (e.g. routine program monitoring, surveys) in most country contexts, though some may require special studies or research.

Interim Assessement Report
The EMA review was started by the Agency’s Committee for Medicinal Products for Human Use (CHMP) to support decision-making by health authorities. This first interim report includes information on seven experimental medicines intended for the treatment of people infecte...d with the Ebola virus:
BCX4430 (Biocryst);
Brincidofovir (Chimerix);
Favipiravir (Fujifilm Corporation/Toyama);
TKM-100802 (Tekmira);
AVI-7537 (Sarepta);
ZMapp (Leafbio Inc.);
Anti-Ebola F(ab’)2 (Fab’entech).
The amount of information available for the seven treatments is highly variable. For some compounds there is no data from use in human subjects available. A small number of treatments have been administered to patients in the current Ebola outbreak as compassionate use. Finally, there are also medicines included in this review that have already been studied in humans, albeit for the treatment of other viral diseases.
