An Outbreak of Cholera Associated with an Unprotected Well in Parbatia, Orissa, Eastern India
In November 2003, an outbreak (41 cases; attack rate–4.3%; no deaths) of severe diarrhoea was reported from a village in Orissa, eastern India. Thirteen of these cases were hospitalized. A matched case-control study was conducted to identify the possible exposure variables. Since all wells were heavily chlorinated immediately after the outbreak, water samples were not tested. The cases were managed symptomatically. Descriptive epidemiology suggested clustering of cases around one public well. Vibrio cholerae El Tor O1, serotype Ogawa was isolated from four of six rectal swabs. The water from the public well was associated with the outbreak (matched odds ratio: 12; 95% confidence interval 1.2–44.1). On the basis of these conclusions, access to the well was barred immediately, and it was protected. This investigation highlighted the broader use of field epidemiology methods to implement public-health actions guided by epidemiologic data to control a cholera epidemic
An Outbreak of Cholera Associated with an Unprotected Well in Parbatia, Orissa, Eastern India
In November 2003, an outbreak (41 cases; attack rate\u20134.3%; no

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Mortality from Aspiration Pneumonia: Incidence, Trends, and Risk Factors
Aspiration pneumonia is a potentially preventable, aggressive type of pneumonia. Little is understood on the burden in mortality from aspiration pneumonia. Our objectives were to first examine the burden of mortality from aspiration pneumonia in the United States and second investigate comorbidities associated with aspiration pneumonia to understand risk factors. We conducted a case-control study of individuals who died of aspiration pneumonia matched to those who died of other causes. We analyzed all deaths in the United States using the Multiple Cause of Death Dataset from 1999-2017. Cases were matched with controls based on age, sex, and race. We calculated age-adjusted mortality rates, annual percentage changes in aspiration pneumonia mortality and matched odds ratio comparisons. We identified a total of 1,112,944 deaths related to aspiration pneumonia from 1999-2017 or an average of 58,576 per year (age-adjusted mortality rate, 21.85 per 100,000 population; 95% confidence interval (CI) 21.78-21.92). Aspiration pneumonia was reported as the underlying cause of death in 334,712 deaths or an average of 17,616 deaths per year (30.1% of the total aspiration pneumonia-associated deaths). Individuals 75 years old or older accounted for 76.0% of aspiration pneumonia deaths and the age adjusted rate ratio was 161.0 (CI 160.5-161.5). Neurologic, upper gastrointestinal, and pulmonary conditions as well as conditions associated with sedative substances were more often associated with aspiration pneumonia-associated deaths. Aspiration pneumonia is the underlying cause or a cofactor in tens of thousands of deaths each year in the United States. Aspiration pneumonia-associated deaths are highly prevalent with advanced age and are associated with neurologic, upper gastrointestinal and pulmonary conditions
