Danish Twin

The Danish Twin Register, which comprises all twins born in Denmark between 1870 and 1920, has been used for studies of selected problems in the field of epidemiology and public health. This report gives a survey of the preliminary results of an investigation of this type, which intends to amplify the present knowledge about the possible harmful effects of smoking on health, by taking advantage of a twin material which makes it possible to keep the genetic factors under control.A series of 762 MZ and same-sexed DZ twin pairs, which had their smoking habits mapped in 1959, has been followed continuously, and the mortality which has occurred in this group has been analysed in relation to tobacco consumption. Neither MZ nor DZ pairs showed any tendency to increased mortality in the heavier smoking cotwins. When the material was subdivided according to cause of death, no conspicuous exception from the general pattern was found, but the subgroups were relatively small.The distribution of selected diseases and symptoms, mainly of the cardiovascular and respiratory systems, was studied in this and a second series, followed since 1966, with a total of 1584 pairs.

Danish Twin

Previous studies on schizophrenia in twins have quite recently been reviewed in detail by Gottesman and Shields (1966a) and Shields (1968). The indications of concordance in different series are highly diverging, in monozygotic pairs ranging from near unity to zero. The high concordance rates found by Luxenburger (1928), Kallmann (1946) and Slater (1953) stress the importance of genetic factors in the aetiology of schizophrenia, whereas the low concordance rate in two recent Scandinavian twin series (Tienari, 1963; Kringlen, 1966) has given rise to the question whether special genetic or environmental factors prevail in some populations. It has, therefore, been found of interest to study schizophrenia in a Danish twin population.

Background: New York City is a gateway for emerging pathogens and global threats. In 2013, faculty from Montefiore Medical Center and Memorial Sloan Kettering developed a free half-day workshop for postgraduate trainees in antimicrobial stewardship (AS), infection prevention (IP), hospital epidemiology, and public health. This annual workshop, sponsored by the Infectious Diseases Society of New York (IDSNY), incorporates case studies and expert panel discussions on timely topics such as Ebola, Candida auris, Clostridiodes difficile, measles, nosocomial influenza, drug shortages, and AS/IP “big data.” Methods: From 2013 through 2017, the workshop involved 10–15 interactive AS/IP cases with audience response questions and panel discussions. In 2018–2019, based on feedback, the format was revised to emphasize breakout sessions in which participants actively practiced AS/IP tools, (eg, medication utilization evaluations, epidemiologic curves, and performance improvement devices). Examples of 2018–2019 cases are shown in Figure 1. A pre- and postseminar paper survey was conducted yearly to understand baseline training in AS/IP, desire for future AS/IP careers, and self-reported effectiveness of the workshop. Results: Initially, the primary audience was NYC ID fellows. From 2018 onward, we opened enrollment to pharmacy residents. Approximately 45 NYC ID fellows were eligible for the course each year. Results from 2013 to 2016 surveys were reported previously (Fig. 2). There were 32 attendees in 2018, 42 in 2019. The survey response rate was 88% in 2018 and 95% in 2019, with 68 (92%) total participants. Most participants had received previous training in IP (82%) and AS (94%) (Fig. 3). Most participants reported that the program was a good supplement to their ID training (98%) and that case studies were an effective means of learning IP (100%) and AS (98%). Furthermore, 92% stated they would like additional AS/IP training, and many since 2013 have requested a full-day course. Self-reported interest in future involvement in AS/IP increased after the workshop: IP, 68%–83% (P =.04) and AS, 88%–91% (P = .61). Conclusions: Most trainees reported satisfaction with the workshop and case-study learning method; interest in future AS/IP careers increased after the seminar. We intend to explore Funding: to expand to a full-day program for all NYC postgraduate trainees and AS/IP junior faculty. As such, we hope to obtain the endorsement of professional societies such as SHEA. This workshop could address a crucial educational gap in AS/IP postgraduate training and help sustain our future workforce.Funding: NoneDisclosures: None

Investigation of an outbreak of hepatitis in Dhaka implicated enterically transmitted non-A, non-B (ET-NANB) hepatitis as the etiologic agent. This observation was made by exclusion in 17 of 19 patients, and confirmed serologically in one randomly selected patient by a fluorescent antibody blocking assay specific for ET-NANB hepatitis. These findings reinforce earlier suspicions that ET-NANB may be an important cause of acute hepatitis in Bangladesh. The epidemiology of ET-NANB hepatitis is discussed, and public health recommendations are made.

Low And Middle Income

SummarySuicide, a common cause of death in many low- and middle-income countries, has often been viewed through a medical/psychiatric lens. Such perspectives medicalise social and personal distress and suggest individual and medication-based treatments. This editorial argues for the need to examine suicide from a public health perspective and suggests the need for population-based social and economic interventions.
