Associations between perceived neighborhood environment and cognitive function among middle-aged and older women and men: Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study

Purpose: To examine cross-sectional associations between perceived neighborhood environment and cognitive function among middle-aged and older Hispanic/Latino women and men. Methods: Data from the Hispanic Community Health Study/Study of Latinos (2008–2011) and its Sociocultural Ancillary Study (2009–2010) were used. Participants were Hispanic/Latino women (n = 1812) and men (n = 1034) aged 45–74 years. Survey-weighted linear regression models were used to examine associations between self-reported perceived neighborhood environment (i.e., neighborhood social cohesion and problems categorized as quintiles, and neighborhood safety from crime categorized as low, medium, or high) with cognitive function (i.e., global cognition, verbal learning, memory, verbal fluency, and processing speed scores) in women and men. Final model adjusted for age, Hispanic/Latino background, language, field site, household income, education, years lived in neighborhood, and depressive symptoms. Results: Women in the lowest quintile of perceived neighborhood problems (vs. highest quintile) had higher global cognition (β 0.48, 95% CI 0.03, 0.94, p trend 0.229) and memory scores (0.60, 95% CI 0.11, 1.09, p trend: 0.060). Women in the highest quintile of perceived neighborhood social cohesion (vs. lowest quintile) had lower global cognition (β − 0.56, 95% CI − 1.02, − 0.09, p trend 0.004), verbal learning (B − 1.01, 95% CI − 2.00, − 0.03, p trend 0.015), verbal fluency (B − 2.00, 95% CI − 3.83, − 0.16, p trend 0.006), and processing speed (B − 2.11, 95% CI − 3.87, − 0.36, p trend 0.009). There was no association between perceived neighborhood safety from crime and cognition among women, or between any perceived neighborhood environment measure and cognition among men. Conclusions: Middle-aged and older Hispanic/Latina women living in neighborhoods with the lowest perceived problems had higher global cognition and memory. Women living in neighborhoods with the highest perceived social cohesion had lower global cognition, verbal learning, verbal fluency, and processing speed

ESCAPE pain trial - The effects of Curcumin in pain relief in women diagnosed with primary dysmenorrhea: A triple blinded, placebo-controlled, phase II, randomized clinical trial protocol

ntroduction: Primary dysmenorrhea affects many women, being a major cause of absenteeism and reduced productivity at work and at school. Although non-steroidal anti-inflammatory drugs (NSAIDs) are a good treatment option, up to 18% of women show no response or present allergic reactions and adverse events. Curcumin has antispasmodic, antinociceptive and both specific and nonspecific anti-inflammatory effects, with good tolerability and safety. To date, no previous trial involving curcumin and dysmenorrhea pain has been performed. Therefore, our main goal is to assess the efficacy of curcumin for pain relief among women with primary dysmenorrhea, along with determining curcumin\u2019s adverse effects and tolerability profile. Methods:A phase II, single-center, randomized, triple-blinded, placebo-controlled, parallel-group, superiority trial to evaluate the effect of curcumin (500 mg/12h) in pain reduction in women (18 to 35-year-old) with primary dysmenorrhea. A first cycle will be used for a passive, observational run-in phase. A sample of 108 participants (54 per group) is necessary to detect a 30% difference in pain sensitivity between groups assessed by visual analogue scale (VAS). Secondary outcomes include side effects, Cox Menstrual Symptom Scale (CMSS), and use of rescue drugs for pain relief. Discussion: Clinical evidence has shown analgesic and anti-inflammatory effects of curcumin and in view of dysmenorrhea\u2019s physiopathology being related to those mechanisms targeted by curcumin, we hypothesize its use could represent an innovative and effective therapy to reduce the severity of this disease and its symptoms.Keywords:primary dysmenorrhea, Curcumin, pain relief, Visual Analogue Scale, Cox Menstrual Sympto
