Given that New York State's (NYS) was the first epicenter of the COVID-19 pandemic in the United States (US), we were interested in potential racial/ethnic differences in pregnancy-related experiences among women pregnant during versus prior to the pandemic. We surveyed 1,525 women (18-44 years) proportionate to geographic and sociodemographic distribution between June 9, 20 and July 21, 20. We carried out bivariate analysis of various social and pregnancy-related factors by racial/ethnic identity (White, Black, Hispanic) and binary logistic and linear regression assessing the association between race/ethnicity, pregnancy prior to/during the pandemic, demographic characteristics, health and social wellbeing, and employment as an essential worker with pregnancy-related healthcare delays and changes. Overall, Black and Hispanic women were significantly more likely to experience a host of negative prenatal and postpartum experiences. In general, multivariate analyses revealed that individuals who were pregnant during the pandemic, lived in NYC, participated in social welfare programs, lacked health insurance, and/or were essential workers were more likely to report delays in prenatal and postpartum care and/or more changes/negative experiences. In light of previous evidence of racial disparities in birth experiences, the higher rates of negative pregnancy/birth-care and postpartum/newborn-care experiences among Black and Hispanic women in bivariate analysis warrant further inspection given that their aggregation for multivariate analysis may have obscured differences at the level of individual events. Findings support continued efforts for universal health insurance and improved social welfare programs. Guidelines are needed to protect essential workers' access to health services, particularly related to pregnancy given the time-sensitive nature of this care.Supplemental data for this article is available online at https://doi.org/10.1080/08964289.2021.1997893 .

Age-related cognitive impairment has been associated with arterial stiffening and decreased cardiorespiratory fitness. The aims of this cross-sectional study were to compare cognitive function domains and cardiovascular parameters in older adults (≥ 65 years old) with high and normal aortic stiffness (via carotid-femoral pulse wave velocity, cfPWV) and to explore relationships among cfPWV, carotid intima-media thickness, cardiorespiratory fitness, and cognitive function. Vascular and cognitive function were measured in older adults with either normal or high cfPWV. Cognitive function was measured via an intensive one-time neuropsychological battery, while cfPWV by applanation tonometry, carotid intima-media thickness and function (i.e., distensibility) by ultrasonography, and cardiorespiratory fitness (i.e., VO₂peak) by a submaximal exercise test. Correlations among age, VO₂peak, carotid intima-media thickness, cfPWV, and cognitive function were performed along with a series of multivariate analyses of variance. Compared with NAS, participants with HAS had greater aortic, carotid, and brachial blood pressures but similar cardiorespiratory fitness and carotid intima-media thickness and distensibility. Participants with NAS exhibited better neuropsychological performance in executive function and attention and overall cognitive function than those with HAS. When controlling for age, visual scanning and perception scores were correlated with cfPWV and VO₂peak. Our findings suggest that certain cognitive domains for older adults are associated with their cardiorespiratory fitness and aortic stiffness.

Sexual minority stressors (community homophobia, sexuality-related discrimination, and internalized homonegativity) are negatively associated with accessing HIV prevention services among men who have sex with men (MSM). Few studies have tested minority stressors' associations with PrEP engagement among high-HIV risk young MSM (YMSM). Therefore, we assessed the associations between PrEP-indicated YMSM's progression along the PrEP continuum and their experiences of minority stress. N = 229 YMSM completed a web-survey on PrEP-related behaviors and minority stress. Adjusted for covariates, we developed two partial-proportional odds models examining the associations between PrEP continuum progression and minority stressors, as a composite, and community homophobia, sexuality-related discrimination, and internalized homonegativity, respectively. Our multivariable model demonstrated minority stress levels to be negatively associated with PrEP continuum location (AOR = 0.76, 95% CI: 0.58-0.99). Broken down, discrimination was positively associated with reporting being at an advanced location along the continuum (AOR = 1.39, 95% CI: 1.06-1.82). Internalized homonegativity was negatively associated with continuum location between PrEP-aware participants with no intention to initiate and participants who intended to initiate PrEP (AOR = 0.45, 95% CI: 0.27-0.77) and between those who intended to initiate and those who had ever used PrEP (AOR = 0.39, 95% CI: 0.22-0.69). Our findings suggest that minority stress, especially internalized homonegativity, remains a barrier to PrEP among PrEP-indicated YMSM. Sexuality-related discrimination was associated with PrEP continuum progression, suggesting potentially well-developed, adaptive coping skills (e.g., ability to locate sexuality-affirming providers). Coupled with stigma reduction efforts, HIV prevention services aiming to promote PrEP should incorporate internalized homonegativity screenings and referrals into sexuality-affirming resources for PrEP-indicated YMSM.

Baby-boomers might be more health-conscious than earlier birth cohorts, but limited evidence has been produced so far. To investigate such changes, this study compared health-related behaviors at age 65 to 70 among three successive five-year birth cohorts (pre-war: born 1934-1938; war: born 1939-1943 and baby-boom: born 1944-1948) representative of the community-dwelling population. Information about alcohol use, smoking, physical activity, and nutrition was compared across the three cohorts (n = 4,270 participants) using Chi-squared test. Alcohol and the mean nutritional intake score did not vary across cohorts, whereas the consumption of nonalcoholic drinks increased significantly from pre-war to war and to baby-boom cohort (p<.001). Other differences across cohorts were observed only in women: the proportion of women who never or rarely engaged in sports decreased from 52.9% in the pre-war cohort to around 43% in subsequent cohorts (p<.001), while the proportion of women who had never smoked was higher in the pre-war cohort (56.1%) than in the war and the baby-boom cohorts (49.8% and 46.8%, respectively, p<.001). Overall, these results show some positive changes in older persons' health behaviors over time. Nevertheless, considerable room remains for improving lifestyles through public health interventions.

Opioid misuse is a significant public health concern with substantial medical, social, and economic costs. Cross cutting the personal and societal effects of this current crisis, opioid misuse is associated with poorer physical and mental health outcomes that impair function across numerous life domains. Importantly, opioid misuse disproportionately affects persons with chronic pain and individuals who smoke tobacco. Despite the higher risk for smokers with chronic pain to engage in opioid misuse, little work has examined how opioid misuse may be related to mental health problems, including other substance use, among this vulnerable group. The current study examined opioid misuse as a predictor of substance use and mental health problems among 187 (M_age = 39.02, SD = 9.94, 74.9% female) daily cigarette smokers with chronic pain who currently use opioids. Results indicated that opioid misuse is associated with greater tobacco (13% of variance), alcohol (27% of variance), and cannabis (22% of variance) problems, as well as anxiety (26% of variance) and depressive symptoms (26% of variance). These results highlight the potential importance of opioid misuse in terms of concurrent substance and mental health problems among smokers with chronic pain. Future work is needed to explicate directionality and temporal ordering in the observed relations.

There is evidence regarding the presence of alterations in both the stress response and the endogenous pain modulation systems of people with fibromyalgia (FM). However, research on pain modulation under induced stress on FM patients is scarce and contradictory. The present study analyzes stress-induced changes in pain and intolerance thresholds among FM patients, examining the possible existence of differences linked to PTSD comorbidity and gaining insights into the role of cardiovascular reactivity. Eighteen women diagnosed with FM and comorbid PTSD (FM + PTSD), 18 women diagnosed with FM and no PTSD (FM-PTSD), and 38 healthy women (HC) were exposed to the Social Stress Test task. Pressure pain thresholds and intolerance thresholds were measured before and during stress induction, and after a recovery period, while systolic blood pressure and heart rate were simultaneously recorded. Overall, while pain thresholds decreased during stress and recovery for HC, no significant changes were observed for women with FM. The intolerance threshold decreased for HC during stress, but was maintained at basal level during recovery. FM-PTSD women exhibited a delayed response, with a drop at recovery. For FM + PTSD, tolerance levels remained unchanged. In addition, cardiovascular reactivity did not seem to explain these results. This performance of the pain modulation system seems to follow the same pattern of hypoactive responsiveness under stressors that has previously been observed in FM patients on the autonomic and neuroendocrine axes. Such a hypoactive pattern may involve a non-adaptive response that may contribute to the development and maintenance of chronic pain.

Previous studies have shown an association between the number of withdrawal attempts and increased severity of withdrawal symptoms in patients with an alcohol use disorder (AUD). An underlying allostatic neuroadaptive response may negatively affect the withdrawal pathology after alcohol discontinuation. The objective of the present research is to examine the intensification of psychiatric distress, craving, and post-detoxification drinking outcomes, which may result from these neurobehavioral alternations. Fifty-two AUD inpatients were divided into two groups: <2 previous detoxifications and ≥2 previous detoxifications. Patients completed the Dutch version of the Severity of Withdrawal Scale (SWS), Depression Anxiety Stress Scales (DASS-21), VAS Craving, and Desires for Alcohol Questionnaire (DAQ). Linear mixed effects models were applied, controlling for the number of drinks consumed in the past 30 days and alcohol drinking history (years). Patients who had undergone ≥2 detoxifications reported statistically significantly higher scores on SWS withdrawal and DASS psychiatric symptoms. Also, craving patterns were different between groups, as shown by a statistically significant interaction effect for VAS craving for the time of day factor (morning vs. evening). No statistically significant group differences were found for DAQ scores and post-detoxification drinking outcomes. Due to relatively low 1-month follow-up rates our power was limited to detect such a difference. The present study contributes to the existing body of evidence that multiple detoxifications are associated with aggravated withdrawal/psychiatric pathology, and distinct diurnal patterns of VAS craving. Several clinical implications are discussed and alternative strategies are provided to manage repeated cycles of detoxifications.
