RESUMO

This study uses data from electronic health records to examine the rate of tubal sterilization requests in 3 periods before and after the US Supreme Court's 2022 Dobbs v Jackson Women's Health Organization decision, compared with the same periods in 2019 and 2021, at a single institution in Michigan.

RESUMO

PURPOSE: Researchers' obligations to disclose genetic incidental findings (GIFs) have been widely debated, but there has been little empirical study of the engagement of institutional review boards (IRBs) with this issue. METHODS: This article presents data from the first extensive (n = 796) national survey of IRB professionals' understanding of, experience with, and beliefs surrounding GIFs. RESULTS: Most respondents had dealt with questions about GIFs (74%), but only a minority (47%) felt prepared to address them. Although a majority believed that there is an obligation to disclose GIFs (78%), there is still not consensus about the supporting ethical principles. Respondents generally did not endorse the idea that researchers' additional time and effort (7%), and lack of resources (29%), were valid reasons for diminishing a putative obligation. Most (96%) supported a right not to know, but this view became less pronounced (63%) when framed in terms of specific case studies. CONCLUSIONS: IRBs are actively engaged with GIFs but have not yet reached consensus. Respondents were uncomfortable with arguments that could be used to limit an obligation to return GIFs. This could indicate that IRBs are providing some of the impetus for the trend toward returning GIFs, although questions remain about the relative contribution of other stakeholders.Genet Med 18 7, 705-711.

RESUMO

BACKGROUND: Social media, including mobile technologies and social networking sites, are being used increasingly as part of human immunodeficiency virus (HIV) prevention and treatment efforts. As an important avenue for communication about HIV, social media use may continue to increase and become more widespread. OBJECTIVE: The objective of this paper is to present a comprehensive systematic review of the current published literature on the design, users, benefits, and limitations of using social media to communicate about HIV prevention and treatment. METHODS: This review paper used a systematic approach to survey all literature published before February 2014 using 7 electronic databases and a manual search. The inclusion criteria were (1) primary focus on communication/interaction about HIV/acquired immunodeficiency syndrome (AIDS), (2) discusses the use of social media to facilitate communication, (3) communication on the social media platform is between individuals or a group of individuals rather than the use of preset, automated responses from a platform, (4) published before February 19, 2014, and (5) all study designs. RESULTS: The search identified 35 original research studies. Thirty studies had low or unclear risk of at least one of the bias items in the methodological quality assessment. Among the 8 social media platform types described, short message service text messaging was most commonly used. Platforms served multiple purposes including disseminating health information, conducting health promotion, sharing experiences, providing social support, and promoting medication adherence. Social media users were diverse in geographic location and race/ethnicity; studies commonly reported users aged 18-40 years and users with lower income. Although most studies did not specify whether use was anonymous, studies reported the importance of anonymity in social media use to communicate about HIV largely due to the stigma associated with HIV. The ability to share and receive information about HIV was the most commonly reported benefit of social media use and the most common challenges were related to technology. Measures of frequency of use, satisfaction, and effects of use varied across studies. CONCLUSIONS: Using social media to bridge communication among a diverse range of users, in various geographic and social contexts, may be leveraged through pre-existing platforms and with attention to the roles of anonymity and confidentiality in communication about HIV prevention and treatment. More robust research is needed to determine the effects of social media use on various health and social outcomes related to HIV.

RESUMO

The rapid growth of next-generation genetic sequencing has prompted debate about the responsibilities of researchers toward genetic incidental findings. Assuming there is a duty to disclose significant incidental findings, might there be an obligation for researchers to actively look for these findings? We present an ethical framework for analyzing whether there is a positive duty to look for genetic incidental findings. Using the ancillary care framework as a guide, we identify three main criteria that must be present to give rise to an obligation to look: high benefit to participants, lack of alternative access for participants, and reasonable burden on researchers. Our analysis indicates that there is no obligation to look for incidental findings today, but during the ongoing translation of genomic analysis from research to clinical care, this obligation may arise.

RESUMO

OBJECTIVE: To examine the impact of low-density lipoprotein (LDL), an established mediator of atherosclerosis, on the transcription factor cAMP-response element-binding protein (CREB), which is a regulator of vascular smooth muscle cell (VSMC) quiescence. METHODS AND RESULTS: VSMC CREB content is diminished in rodent models of diabetes and pulmonary hypertension. We examined aortic CREB content in rodent models of aging, hypertension, and insulin resistance, and we determined nuclear CREB protein in the medial VSMC of high-fat-fed LDL receptor-null mice. There was significant loss of CREB protein in all models. In vitro, primary culture rat aortic VSMC exposed to LDL and oxidized LDL exhibited a rapid, transient increase in CREB phosphorylation and transient phosphorylation/activation of Akt, ERK, JNK, ans p38 MAPK. Exposure to oxidized LDL, but not to LDL, for 24 to 48 hours decreased CREB protein in a dose-dependent fashion and led to nuclear exclusion of CREB. Pharmacological reactive oxygen species scavengers and inhibition of ERK activation blocked oxidized LDL-mediated CREB downregulation. CONCLUSIONS: These data support a model wherein loss of VSMC CREB protein, which renders these cells more susceptible to activation and apoptosis, is a common pathological response to vascular injury and potentially contributes to plaque progression.
