Characterizing Intervention Strategies Used in Community-Based Mental Health Care for Infants and Their Families
Abstract
Mental health interventions for infants typically target high-risk groups and can prevent long-term negative outcomes. Despite federal initiatives promoting early intervention, minimal research has examined usual care services for infants, which is important to improve routine care. The current study characterized usual care practices in infant mental health through the adaptation and administration of a provider survey. Providers (n = 126) reported using a wide range of intervention strategies and few intervention programs with varied evidence. Findings can inform future research to identify quality improvement targets of usual mental health care for high-risk infants and their families.

Foreign-Born Blacks Experience Lower Odds of Obesity but Higher Odds of Diabetes than US-Born Blacks in New York City
Abstract
Research is limited on the health of foreign-born Blacks (FBBs), who are often grouped with African Americans. This study compared obesity and diabetes odds in FBBs and US-born Blacks (USBBs) in NYC. Analyzing the 2009–2013 NYC Community Health Survey (3701 FBBs and 6297 USBBs), weighted multivariate logistic regression examined odds of obesity and diabetes, adjusting for age, gender, education, income, marital status, children < 18, BMI (for diabetes only) and duration of residence. FBBs had lower odds of obesity [OR 0.62 (95% CI 0.54, 0.72)] and greater odds of diabetes [OR 1.24 (95% CI 1.01, 1.52)] compared to USBBs. FBBs had 1.4 times the odds of diabetes at overweight status, compared to USBBs [OR 1.40 (95% CI 1.01, 1.95)]. Living in the US ≥ 10 years was not associated with odds of obesity and diabetes. Future research should seek to uncover unique risk profiles of sub-ethnic groups in the African diaspora.

Reduced arterial vasodilation in response to hypoxia impairs cerebral and peripheral oxygen delivery in hypertensive men
Abstract
This study investigated whether hypertension impairs isocapnic hypoxia (IH)-induced cerebral and skeletal muscle hyperemia to an extent that limits oxygen supply. Oxygen saturation (Oxymetry), mean arterial pressure (MAP, photoplethysmography), muscle sympathetic nerve activity (MSNA, microneugraphy), and femoral (FA), internal carotid (ICA) and vertebral (VA) artery blood flow (BF, Doppler ultrasound) were quantified in 9 normotensive (NT, 40 ± 11 yrs., systolic (SP) 119 ± 7 mmHg and diastolic pressure (DP) 73 ± 6 mmHg) and 9 hypertensive men (HT, 44 ± 12 yrs., SP 152 ± 11 mmHg and DP 90 ± 9 mmHg) during 5 min of normoxia (NX – 21% O2) and IH (10% O2). Total cerebral blood flow (tCBF), brain (CDO2) and leg (LDO2) oxygen delivery were estimated. IH provoked similar oxygen desaturation without changing MAP. ICA perfusion increased in both groups during IH. However, VA and FA BF only increased in NT. Thus, IH-induced increase in tCBF was smaller in HT. CDO2 only increased in NT and LDO2 decreased in HT. Furthermore, IH evoked a greater increase in HT MSNA. Changes in MSNA were inversely related to FA BF, LDO2 and end-tidal oxygen tension. In conclusion, hypertension disturbs regional and total cerebrovascular and peripheral responses to IH and consequently limits oxygen supply to the brain and skeletal muscle. While increased chemoreflex-induced sympathetic activation may explain impaired peripheral perfusion, attenuated vasodilatory signalling in the posterior cerebrovasculature seems responsible for the small increase in tCBF when HT were exposed to IH.
