The ventilation of buildings and other mitigating measures for COVID-19: a focus on wintertime.

The year 2020 has seen the emergence of a global pandemic as a result of the disease COVID-19. This report reviews knowledge of the transmission of COVID-19 indoors, examines the evidence for mitigating measures, and considers the implications for wintertime with a focus on ventilation.This work was undertaken as a contribution to the Rapid Assistance in Modelling the Pandemic (RAMP) initiative, coordinated by the Royal Society

When the cause of death does not exist: time for the WHO to close the ICD classification gap for Medical Aid in Dying.

UNLABELLED: Medical aid in dying (MAID) is a highly controversial ethical issue in the global medical community. Unfortunately, the International Classification of Diseases (ICD) of the World Health Organization (WHO) lacks coding for MAID. Therefore, no robust data adequately monitors worldwide trends that include information on diseases and conditions underlying the patients request for assisted dying (MAID gap). Countries with legalised MAID observe substantial increases in cases, and likely additional countries will allow MAID in the near future. Hence, we encourage the WHO to create specific ICD codes for MAID. According to internationally established practices, a revised classification would require separate MAID-codes for (1) assisted suicide and (2) voluntary active euthanasia including supplemental codings of diseases, clusters of symptoms and function-oriented categories. By addressing these concerns, the WHO could close the MAID gap with new codes providing urgently necessary insights to society, public health decision-makers and regulators on this comparatively new social and medical ethical phenomenon. SEARCH STRATEGY AND SELECTION CRITERIA: Data for this Viewpoint were identified by searches of MEDLINE, PubMed, and references from relevant articles using the search terms Medical Aid in Dying, Assisted Dying, Assisted suicide, Voluntary active euthanasia, End of life decisions and Cause of death statistics. Only articles and sources published in English between 1997 and 2023 were included

Prevalence of undiagnosed urinary tract infections on admission to a rehabilitation unit

Background Through clinical observation nursing staff of an inpatient rehabilitation unit identified a link between incontinence and undiagnosed urinary tract infections (UTIs). Further, clinical observation and structured continence management led to the realisation that urinary incontinence often improved, or resolved completely, after treatment with antibiotics. In 2009 a small study found that 30% of admitted rehabilitation patients had an undiagnosed UTI, with the majority admitted post-orthopaedic fracture. We suspected that the frequent use of indwelling urinary catheters (IDCs) in the orthopaedic environment may have been a contributing factor. Therefore, a second, more thorough, study was commenced in 2010 and completed in 2011. Aim The aim of this study was to identify what proportion of patients were admitted to one rehabilitation unit with an undiagnosed UTI over a 12-month period. We wanted to identify and highlight the presence of known risk factors associated with UTI and determine whether urinary incontinence was associated with the presence of UTI. Methods Data were collected from every patient that was admitted over a 12-month period (n=140). The majority of patients were over the age of 65 and had an orthopaedic fracture (36.4%) or stroke (27.1%). Mid-stream urine (MSU) samples, routinely collected and sent for culture and sensitivity as part of standard admission procedure, were used by the treating medical officer to detect the presence of UTI. A data collection sheet was developed, reviewed and trialled, before official data collection commenced. Data were collected as part of usual practice and collated by a research assistant. Inferential statistics were used to analyse the data. Results This study found that 25 (17.9%) of the 140 patients admitted to rehabilitation had an undiagnosed UTI, with a statistically significant association between prior presence of an IDC and the diagnosis of UTI. Urinary incontinence improved after the completion of treatment with antibiotics. Results further demonstrated a significant association between the confirmation of a UTI on culture and sensitivity and the absence of symptoms usually associated with UTI, such as burning or stinging on urination. Overall, this study suggests careful monitoring of urinary symptoms in patients admitted to rehabilitation, especially in patients with a prior IDC, is warranted

ICD-Based Cause of Death Statistics Fail to Provide Reliable Data for Medical Aid in Dying.

Objectives: To evaluate the most recent developments of medical aid in dying (MAID) in Switzerland and to test the reliability of reporting this phenomenon in cause of death statistics. Methods: By reviewing the MAID cases between 2018 and 2020, we compared the diseases and conditions underlying MAID reported by the ICD-based statistics provided by the Swiss Federal Statistical Office (FSO, n = 3,623) and those provided by the largest right-to-die organization EXIT (n = 2,680). Results: EXIT reported the motivations underlying the desire for death in a mixture of disease-specific and symptom-oriented categories; the latter including, for example, multimorbidity (26% of cases), and chronic pain (8%). Symptom-oriented categories were not included in the ICD-based FSO statistics. This led to the fact that the distribution of the diseases/conditions underlying MAID differed in 30%-40% of cases between both statistics. Conclusion: In order to reliably follow developments and trends in MAID, the diseases/conditions underlying the wish to die must be accurately recorded. Current methods of data collection using the ICD classification do not capture this information thoroughly (MAID gap). Newly created ICD codes for MAID must include both disease-specific and symptom-oriented categories
