Association of mindfulness and stress with menopausal symptoms in midlife women.

Purpose: Midlife women frequently experience stress and menopausal symptoms. Mindfulness is thought to mitigate stress by avoiding emotional reactivity and ruminative thinking. We sought to assess the association of mindfulness and stress on menopausal symptoms among midlife women. Materials and methods: In this cross-sectional study, women aged 40-65 years completed questionnaires, including the Menopause Rating Scale (MRS), the Perceived Stress Scale-4 (PSS-4), and the Mindfulness Attention Awareness Scale (MAAS). Linear regression was used to assess the impact of mindfulness and stress on menopausal symptoms with use of univariate and multivariable analyses, adjusting for patient characteristics. Results: In this cohort of 1744 midlife women, higher mindfulness (MAAS) and lower stress (PSS-4) scores correlated independently with lower menopausal symptom (MRS) scores. On multivariable analysis, a significant interaction effect was observed between the MAAS and PSS-4 on the MRS, such that with higher PSS-4 scores, the magnitude of association between the MAAS and lower MRS scores was larger. Conclusion: Among midlife women, higher mindfulness and lower stress correlated with lower menopausal symptom scores independently. Among women experiencing more stress, the magnitude of association between mindfulness and lower menopausal symptom scores was greater, largely driven by psychological subdomain scores. Mindfulness may mitigate menopausal symptoms among midlife women.

A negative view of menopause: does the type of symptom matter?

OBJECTIVES: To assess the association between the type of symptom and women's self-reported view of menopause. METHODS: The study was conducted at Mayo Clinic, Rochester MN, between January 2006 and October 2014. Women aged 40-64 were included. Data from 1420 women were analyzed in a cross-sectional design. The Menopause Health Questionnaire was used for symptom assessment. Odds ratios (ORs) and population attributable risk (PAR) (OR × percent frequency) were calculated for each symptom. Logistic regression analyses were performed with the view of menopause as the dependent variable. RESULTS: Anxiety (2.34), depressed mood (2.24), irritability (2.22), vaginal itching (2.27), crying spells (2.1) and breast tenderness (2.08) were associated with highest odds of having a negative view of menopause. Highest PAR (population impact) symptoms were anxiety (22.27), weight gain (20.66), fatigue (20.28) and irritability (19.41). Hot flushes and night sweats, although common, were not associated with a negative view of menopause (OR 1.3 and 1.16; PAR 3.85 and 4.42, respectively). CONCLUSION: Mood symptoms, vaginal itching, weight gain, breast tenderness and fatigue, although less common than hot flushes, were noted to have greater association with a negative view of menopause. Specifically addressing these symptoms during menopausal consultation may improve patient satisfaction and outcomes.

Methamphetamine acts on subpopulations of neurons regulating sexual behavior in male rats.

Methamphetamine (Meth) is a highly addictive stimulant. Meth abuse is commonly associated with the practice of sexual risk behavior and increased prevalence of Human Immunodeficiency Virus and Meth users report heightened sexual desire, arousal, and sexual pleasure. The biological basis for this drug-sex nexus is unknown. The current study demonstrates that Meth administration in male rats activates neurons in brain regions of the mesolimbic system that are involved in the regulation of sexual behavior. Specifically, Meth and mating co-activate cells in the nucleus accumbens core and shell, basolateral amygdala, and anterior cingulate cortex. These findings illustrate that in contrast to current belief drugs of abuse can activate the same cells as a natural reinforcer, that is sexual behavior, and in turn may influence compulsive seeking of this natural reward.

ΔFosB in the nucleus accumbens is critical for reinforcing effects of sexual reward.

Sexual behavior in male rats is rewarding and reinforcing. However, little is known about the specific cellular and molecular mechanisms mediating sexual reward or the reinforcing effects of reward on subsequent expression of sexual behavior. This study tests the hypothesis that ΔFosB, the stably expressed truncated form of FosB, plays a critical role in the reinforcement of sexual behavior and experience-induced facilitation of sexual motivation and performance. Sexual experience was shown to cause ΔFosB accumulation in several limbic brain regions including the nucleus accumbens (NAc), medial prefrontal cortex, ventral tegmental area and caudate putamen but not the medial preoptic nucleus. Next, the induction of c-Fos, a downstream (repressed) target of ΔFosB, was measured in sexually experienced and naïve animals. The number of mating-induced c-Fos-immunoreactive cells was significantly decreased in sexually experienced animals compared with sexually naïve controls. Finally, ΔFosB levels and its activity in the NAc were manipulated using viral-mediated gene transfer to study its potential role in mediating sexual experience and experience-induced facilitation of sexual performance. Animals with ΔFosB overexpression displayed enhanced facilitation of sexual performance with sexual experience relative to controls. In contrast, the expression of ΔJunD, a dominant negative binding partner of ΔFosB, attenuated sexual experience-induced facilitation of sexual performance and stunted long-term maintenance of facilitation compared to green fluorescence protein and ΔFosB overexpressing groups. Together, these findings support a critical role for ΔFosB expression in the NAc for the reinforcing effects of sexual behavior and sexual experience-induced facilitation of sexual performance.
