Intimate Partner Violence Polyvictimization and Health Outcomes

This study examines how gender interacts with polyvictimization patterns in survivors' health problems using 8,587 survivors of intimate partner violence from the National Intimate Partner and Sexual Violence Survey, a nationally representative sample collected in 2010. Polyvictimization included six categories that were created in our previous work: sexual violence, physical and psychological violence, coercive control, multiple violence, stalking, and psychological aggression. Multiple violence was associated with chronic pain, headache, difficulty sleeping, and poor health perception. Females experiencing coercive control were more likely to have chronic pain than males. The appropriate assessment of gendered patterns of polyvictimization, and relevant subsequent services and support will better address health problems among survivors.

MTHFR c.665C>T guided fluoropyrimidine therapy in cancer: gender-dependent effect on dose requirements

OBJECTIVES

The fluoropyrimidine derivatives 5-Fluorouracil and Capecitabine are widely used for the treatment of solid tumors. Fluoropyrimidine metabolism involves a cascade of different enzymes, including MTHFR enzyme. MTHFR c.665C>T polymorphism, leading to decreased MTHFR activity, is a potential pharmacogenomic marker for fluoropyrimidine drug response. The aim of the present study was to analyze the association of MTHFR c.665C>T polymorphism with fluoropyrimidine response in terms of therapy induced adverse events (AEs), requirement of dose reduction and delayed drug administration or therapy discontinuation.

METHODS

The study group consisted of 313 fluoropyrimidine-treated cancer patients. PCR-RFLP was used to analyze MTHFR c.665C>T polymorphism.

RESULTS

In female patients, MTHFR c.665 CT and TT genotypes were associated with dose reduction (p=0.029). In gender stratification, regression analysis adjusted for age of disease onset, body surface area and AE incidence, showed that MTHFR CT and TT genotypes increased both need for fluoropyrimidine dose reduction (OR 5.050, 95% CI 1.346-18.948, p=0.016) and percentage of dose reduction (β=3.318, 95% C.I. 1.056-5.580, p=0.004) in female patients. Such differences were not present in male patients. No other associations were found.

CONCLUSIONS

MTHFR c.665C>T polymorphism was associated with fluoropyrimidine dose reduction in female cancer patients. This gender*MTHFR interaction merits further investigation.

Gender differences in objectively assessed physical activity in asthmatic and non-asthmatic children

OBJECTIVE

To compare objectively assessed physical activity levels, between asthmatic children and non-asthmatic controls.

METHODS

From a random community sample of 794 children aged 8-9 years, in a case-control design, 104 children with ever doctor's diagnosis of asthma and 99 non-asthmatic controls were recruited and had assessment of physical activity with biaxial accelerometers for 7 days.

RESULTS

Children with active (also reporting at least one episode of wheezing in the last 12 months) and inactive (no wheezing in past 12 months) asthma appeared to have similar physical activity and sedentary activity levels compared to non-asthmatic children. However, girls with active asthma had significantly lower moderate-to-vigorous physical activity (MVPA) levels than their peers with adjusted geometric mean ratio of 0.59 (95% CI: 0.369, 0.929, P-value = 0.024). No difference in physical and sedentary activity levels was observed between asthmatic and non-asthmatic boys. The difference between genders in the comparison of MVPA levels in asthmatics and controls was statistically significant (P-value of likelihood ratio test [LRT] for effect modification by gender = 0.034).

CONCLUSIONS

Unlike boys, girls with active asthma appear to be less active than their healthy peers, and this gender difference might explain the inconsistent evidence from previous reports on physical activity levels in asthmatic children. Further studies are needed to confirm the gender interaction in the childhood asthma-physical activity relation and the implications on current guidelines for physical exercise prescriptions in asthmatic children.

Early life socio-economic position and later alcohol use: birth cohort study

AIMS

To investigate associations between socio-economic position in early life and later alcohol use and problem use among male and female adolescents.

DESIGN

Birth cohort study.

SETTING

South West England.

PARTICIPANTS

A total of 2711 girls and 2379 boys with one or more measures of alcohol use or problem use at age 15 years.

MEASUREMENTS

Exposure measures were highest parental social class, maternal education and household disposable income (all maternal self-report before school-age); outcome measures were heavy typical drinking, frequent drinking, regular binge drinking, alcohol-related psychosocial problems and alcohol-related behavioural problems.

FINDINGS

Alcohol use and related problems were relatively common amongst adolescent girls and boys. Boys were slightly more likely to report frequent drinking and girls were slightly more likely to drink heavily and to experience alcohol-related psychosocial problems. Higher maternal education appeared protective in relation to alcohol-related problems, particularly among boys. Higher household income was associated with greater risk of alcohol use and problem use, most apparently among girls.

CONCLUSIONS

Children from higher-income households in England appear to be at greater risk of some types of adolescent alcohol problems, and these risks appear different in girls compared to boys. Childhood social advantage may not generally be associated with healthier behaviour in adolescence.
