RESUMO
BACKGROUND: Short-term fine particulate matter (PM2.5) exposure is positively associated with acute cardiovascular and respiratory events. Understanding whether this association varies across specific cardiovascular and respiratory conditions has important biologic, clinical, and public health implications. METHODS: We conducted a time-stratified case-crossover study of hospitalizations from 2000 through 2014 among United States Medicare beneficiaries aged 65+. The outcomes were hospitalizations with any of 57 cardiovascular and 32 respiratory discharge diagnoses. We estimated associations with two-day moving average PM2.5 as a piecewise linear term with a knot at PM2.5 = 25 g/m3. We used Multi-Outcome Regression with Tree-structured Shrinkage (MOReTreeS) to identify de novo groups of related diseases such that PM2.5 associations are: (1) similar within outcome groups; but (2) different between outcome groups. We adjusted for temperature, humidity, and individual-level characteristics. We introduce an R package, moretrees. RESULTS: Our dataset included 16,007,293 cardiovascular and 8,690,837 respiratory hospitalizations. Of 57 cardiovascular diseases, 51 were grouped and positively associated with PM2.5. We observed a stronger positive association for heart failure, which formed a separate group. We observed negative associations for groups containing the outcomes other aneurysm and intracranial hemorrhage. Of 32 respiratory outcomes, 31 were grouped and were positively associated with PM2.5. Influenza formed a separate group with a negative association. CONCLUSIONS: We used a new statistical approach, MOReTreeS, to uncover variation in the association between short-term PM2.5 exposure and hospitalizations for cardiovascular and respiratory causes controlling for patient characteristics, time trends, and environmental confounders.

BACKGROUND: The number of affected infants and the types of malformations identified by a malformation surveillance programs can be impacted if elective terminations for malformations are not included. METHODS: The occurrence of malformations in all newborn infants was determined in a daily review of the findings in the pediatricians' examinations and those of all consultants. In addition, the findings in autopsies of all elective terminations were reviewed to identify all fetuses with structural abnormalities. A severity scale was used to subdivide the malformations. To establish the impact of elective termination, the malformed infants identified in the Active Malformations Surveillance Program at Brigham and Women's Hospital in Boston were analyzed for the 2 years before and after the hospital decreased significantly the number of elective terminations temporarily (1999-2000 vs. 2001-2002). The effect on the number of malformations identified at birth, as well as malformations of greater severity, was determined. RESULTS: The number of terminated fetuses with malformations decreased dramatically after termination services were interrupted (p < 0.0001). There were no differences in the prevalence rates of all malformations in the 2 years before and after the change in access to elective terminations. However, there were significant decreases in the number of infants identified with lethal/life-limiting and severe/handicapping malformations. CONCLUSION: In the surveillance for malformations among newborn infants, the inclusion of malformed fetuses from elective terminations had a significant effect on the number of infants with the more severe malformations identified.

Objectives: Advance care planning (ACP) specifies decision-making surrogates and preferences for serious illness or end-of-life medical care. ACP research has largely neglected sexual minority men (SMM), a population that experiences disparities in health care and health status. Methods: We examined formal and informal ACP among SMM ages 40+ in the Multicenter AIDS Cohort Study (N = 1,071). Results: For informal ACP (50%), younger SMM and men with past cardiovascular events had greater odds of planning; single men had lower odds of planning. For formal ACP (39%), SMM with greater socioeconomic status had greater odds of planning; SMM who were younger, of racial/ethnic minority identities, who were single or in a relationship without legal protections, and who lacked a primary care home had lower odds of planning. Discussion: Findings warrant further exploration of both informal and formal planning. More equitable, culturally-humble engagement of SMM may facilitate access, uptake, and person-centered planning.

Home- and community-based services (HCBS) facilitate community living for older adults and persons with disabilities, but limited awareness of HCBS is a significant barrier to access. Social exposure is one potential conduit for HCBS knowledge. To understand the general population's social exposure to HCBS-that is, knowing someone who has used HCBS (including one's self)-we fielded a survey item with a nationally representative panel of U.S. adults. An estimated 53% of U.S. adults reported not knowing anyone who had used HCBS. Exposure rates were low across specific HCBS types (6%-28%). Women had greater exposure than men for eight of the 11 HCBS. We also found differences by age, racial/ethnic identity, rurality, education, and income. Increasing the general public's awareness of HCBS may facilitate access when services are needed, enhance readiness for aging in place, and increase the visibility and inclusion of older adults, persons with disabilities, and caregivers.

OBJECTIVE: People released from prison who experience mental health and substance use problems are at high risk of reincarceration. This study aimed to examine the association between contact with mental health and substance use treatment services, and reincarceration, among adults released from prison. METHODS: Pre-release survey data from 1,115 adults released from prisons in Queensland, Australia were linked with administrative health and correctional records covering a median of 787 days post-release. We constructed marginal structural Cox proportional hazards models, adjusting for pre-release variables and time-varying indicators of emergent mental health and substance use problems, to examine the association between contact with mental health and substance use treatment services, and reincarceration. RESULTS: The adjusted hazard ratio (AHR) for reincarceration associated with mental health service contact was 1.76 (95%CI 1.23,2.51). Among those not on parole following release, the AHR for reincarceration associated with substance use treatment service contact was 3.16 (95%CI 2.09,4.77); we found no evidence for an association among those who were released on parole (AHR = 1.07; 95%CI 0.80,1.43). CONCLUSIONS: Although we cannot eliminate the possibility of residual confounding, our findings suggest that infrequent or unsustained contact with community-based mental health and substance use treatment services is not protective against reincarceration, and may even be iatrogenic. Increased investment in high-quality and timely behavioural health services for people released from prison may simultaneously improve health outcomes, and reduce reincarceration.

Importance: In peer-reviewed medical journals, authoring an invited commentary on an original article is a recognition of expertise. It has been documented that women author fewer invited publications than men do. However, it is unknown whether this disparity is due to gender differences in characteristics that are associated with invitations, such as field of expertise, seniority, and scientific output. Objective: To estimate the odds ratio (OR) of authoring an invited commentary for women compared with men who had similar expertise, seniority, and publication metrics. Design, Setting, and Participants: This matched case-control study included all medical invited commentaries published from January 1, 2013, through December 31, 2017, in English-language medical journals and multidisciplinary journals. Invited commentaries were defined as publications that cite another publication within the same journal volume and issue. Bibliometric data were obtained from Scopus. Cases were defined as corresponding authors of invited commentaries in a given journal during the study period. Controls were matched to cases based on scientific expertise by calculating a similarity index for abstracts published during the same period using natural language processing. Data analyses were conducted from March 13, 2019, through May 3, 2019. Exposure: Corresponding or sole author gender was predicted from author first name and country of origin using genderize.io. Main Outcomes and Measures: The OR for gender was estimated after adjusting for field of expertise, publication output, citation impact, and years active (ie, years since first publication), with an interaction between gender and years active. Results: The final data set included 43â¯235 cases across 2549 journals; there were 34â¯047 unique intraciting commentary authors, among whom 9072 (26.6%) were women. For researchers who had been active for the median of 19 years, the odds of invited commentary authorship were 21% lower for women (OR, 0.79 [95% CI, 0.77-0.81]; P < .001) compared with men who had similar scientific expertise, number of publications, and citation impact. For every decile increase in years active, the OR decreased by a factor of 0.97 (95% CI, 0.96-0.98; P < .001). Conclusions and Relevance: In this case-control study, women had lower odds of authoring invited commentaries than their male peers. This disparity was larger for senior researchers. Journal editors could use natural language processing of published research to widen and diversify the pool of experts considered for commentary invitations.

BACKGROUND: Malformations surveillance programs among newborn infants are used to determine the prevalence of congenital anomalies. A comparison in the same group of infants between the malformations detected at birth and those detected at 1 year of age will identify errors in the surveillance process and, also, the abnormalities more likely not to be detected at birth, but later in the first year of life. METHODS: The malformations identified at birth by Brigham and Women's Hospital (BWH) in the years 2000 and 2005 have been compared with the abnormalities detected in the same infants up to age 1 year by the Massachusetts Birth Defects Monitoring Program. RESULTS: The Massachusetts Birth Defects Monitoring Program identified 557 malformed infants in 2000 and 415 in 2005. Of these, 34 (3.5%) of the malformed infants were missed at birth by BWH Surveillance Program. An additional 22 (2.3%) malformed infants had delayed detection, as they were identified later in the first year. The reasons were the fact that: (1) the Surveillance staff reviewed the physicians' recorded findings only on the first day of life; (2) failure of the examining pediatrician to record the presence of a malformation in her/his notes. The most common abnormalities with delayed detection were mild heart defects, such as atrial septal defects. CONCLUSION: These findings emphasize the importance in a newborn malformations surveillance program of continued follow up in the first days of life, especially in small, premature infants.

BACKGROUND: The evaluation of tools to accurately identify low birth weight (LBW) and/or premature newborns in resource-limited countries is a research priority. We explored the use of foot length, chest circumference, and mid-upper arm circumference (MUAC) measured within 24 h as diagnostic tools for identifying newborns who are LBW, premature, or both; and compared measurements taken at birth with those taken at five days of age. MATERIALS AND METHODS: An observational study was undertaken in Hoa Binh Province General Hospital, Vietnam, in ethnic minority newborns. Birth weight, foot length, chest circumference, and MUAC were measured within 24 h of birth and in a subset of 200, were repeated on day five of life. Gestational age was estimated using the New Ballard Score. Receiver Operating Characteristic curves and optimal cut-points (the point with the highest sensitivity and specificity where the sensitivity was at least 0.8) were calculated, for predicting prematurity, LBW, and both. Measurements within 24 h and at five days of life were compared. RESULTS: 485 newborns were recruited. Chest circumference and MUAC measured within 24 h of birth were found to be highly predictive of LBW (both yielding area under the curve [AUC] of 0.98, 95% confidence interval [CI] 0.96-0.99), and performed marginally better than foot length (AUC 0.94, 95%CI 0.92-0.96). The optimal cut-points for measurements within 24 h of birth were ≤ 7.4 cm for foot length; ≤ 30.4 cm for chest circumference; and ≤ 9.0 cm for MUAC. There was statistical evidence that anthropometric measurements taken within 24 h of birth were higher than measurements on day five (p<0.02 for all anthropometric measurements) but the magnitude of these differences was small (at most 2mm). CONCLUSIONS: All measurements taken within 24 h of birth were good predictors of LBW, prematurity and both. Differences in measurements taken within 24 h and on day five were not clinically relevant. Further research will ensure that the application of these measures is reliable in community settings.
