Pneumocystis carinii pneumonia (PCP) remains a serious opportunistic infection in HIV infected individuals. Seasonal changes in climate are associated with changes within individual susceptibility to infection. The possibility of monthly variability in the incidence of PCP was therefore examined by means of a cohort study of a database of 8640 HIV infected individuals attending the Chelsea and Westminster Hospital. There were 792 cases of PCP diagnosed since 1985. A marked decline was observed in the incidence of PCP in mid-1992 coincident with the introduction of PCP prophylaxis. There was a further decline in 1996 after the introduction of highly active antiretroviral therapy. Despite no significant monthly variation in the mean attendance to clinic and CD4 count, both new and all cases of PCP were higher in January than in other months (15.9% and 14.5% of all cases, respectively). A correlation with low rainfall in January and new cases of PCP was observed. These data are consistent with an influence of climatic conditions on the presentation of PCP. The diagnosis of PCP is more common in winter months suggesting that this is a transmissible infection.
Background In the last decade surgical care has been propelled into the public health domain with the establishment of a World Health Organisation (WHO) designated programme and key publications. The passing of the historic World Health Assembly Resolution (WHA) acknowledged surgical care as a vital component towards achieving Universal Health Coverage (UHC). We conducted the first worldwide survey to explore the perception of surgical care as a public health issue. Method The anonymous, cross sectional survey targeted worldwide participants across a range of professional backgrounds, including non-medical using virtual snowball sampling method (in English) using Google Forms (Google Inc., Mountain View, CA, USA) from 20th February 2019 to 25th June 2019. The survey questions were designed to gauge awareness on Sustainable Development Goals (SDGs), UHC, WHO programmes and key publications on surgical care as well as perception of surgical care as a priority topic in public health. Results The survey was completed by 1954 respondents from 118 countries. Respondents were least aware of surgical care as a teaching topic in public health courses (27%; n = 526) and as a WHO programme (20%; n = 384). 82% of respondents were aware of UHC (n = 1599) and of this 72% (n = 1152) agreed that surgical care fits within UHC. While 77% (n = 1495) of respondents were aware of SDGs, only 19% (n = 370) agreed that surgery was a priority to meet SDGs. 48% (n = 941) rated surgical care as a cost-effective component of Primary Health Care. 88% (n = 1712) respondents had not read the WHA Resolution on ‘Strengthening emergency and essential surgical care and anaesthesia as a component of UHC’. Conclusion There is still a widespread gap in awareness on the importance of surgical care as a public health issue amongst our respondents. Surgical care was not seen as a priority to reach the SDGs, less visible as a WHO programme and not perceived as an important topic for public health courses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
