  • Music as a Therapy to Alleviate Anxiety During Inpatient Rehabilitation for Stroke

    by Maureen Le Danseur, April D. Crow, Sonja E. Stutzman, Marcos D. Villarreal, DaiWai M. Olson

    Purpose: The aim of the study was to determine if listening to music may reduce anxiety experienced by stroke patients during acute rehabilitation. Design: A prospective, nonblinded, randomized study in an inpatient rehabilitation setting. Methods: Fifty participants were randomized into two groups: (1) 1 hour of music (intervention) or (2) no music (control). All participants completed pretest anxiety and depression screening and 44 completed the posttest anxiety screening. Differences between groups were determined using chi-square and t tests. Findings: After listening to music for 1 hour, participants who completed the posttest (n = 44) reported significantly less anxiety (p < .0001) compared to before the intervention. The control group showed no difference in their pre- and posttest anxiety scores (p = .84). No differences were determined among age, gender, or diagnostic groups. Conclusions: These findings demonstrate that music intervention may help lessen anxiety in rehabilitation patients poststroke. Clinical Relevance: Offering musical intervention to stroke patients in rehabilitation may lessen symptoms of anxiety.

    School shootings during 2013–2015 in the USA

    by Bindu Kalesan, Kinan Lagast, Marcos Villarreal, Elizabeth Pino, Jeffrey Fagan, Sandro Galea

    Background Data on the factors associated with school shootings in the USA are limited. The public conversation has often suggested several factors that may be linked to these events, however with little empirical support. Aiming to fill this gap, we describe the characteristics of school shooting incidents in the USA between 2013 and 2015 and explore whether four factors that represent domains of firearm policy, educational policy and epidemiological risk factors for intentional firearm injuries-background check (BC) policies, per capita mental health expenditures (MHE), K-12 education expenditure (KEE) and urbanicity—were associated with school shootings during this period. Methods We searched LexisNexis, a newspaper and broadcast media databases for school shooting incidents from 1 January 2013 to 31 December 2015. Presence of BC laws was extracted from legal information in LexisNexis. State-level covariates of per capita MHE (2013), KEE (2013) and urbanicity (2010) rates were obtained from publicly available data sources. We used negative binomial regression models accounting for clustering by state to explore unadjusted associations between the BC laws, state-level covariates and school shootings to report IRR and 95% CI. Results We documented 154 school shootings (35, 55 and 64 each year). In unadjusted models, BC for firearm purchase (IRR=0.55, 95% CI 0.39 to 0.76), ammunition purchase (IRR=0.11, 95% CI 0.05 to 0.27), log per capita MHE (IRR=0.58, 95% CI 0.37 to 0.90), log per-capita KEE (IRR=0.09, 9% CI 0.02 to 0.29) and urbanicity (IRR=0.97, 95% CI 0.96 to 0.99) were associated with school shooting. Conclusions School shootings are less likely in states with BC laws, higher MHE and KEE, and with greater per cent urban population.

    Gun ownership and social gun culture

    by Bindu Kalesan, Marcos D Villarreal, Katherine M Keyes, Sandro Galea

    We assessed gun ownership rates in 2013 across the USA and the association between exposure to a social gun culture and gun ownership. We used data from a nationally representative sample of 4000 US adults, from 50 states and District of Columbia, aged >18 years to assess gun ownership and social gun culture performed in October 2013. State-level firearm policy information was obtained from the Brady Law Center and Injury Prevention and Control Center. One-third of Americans reported owning a gun, ranging from 5.2% in Delaware to 61.7% in Alaska. Gun ownership was 2.25-times greater among those reporting social gun culture (PR=2.25, 95% CI 2.02 to 2.52) than those who did not. In conclusion, we found strong association between social gun culture and gun ownership. Gun cultures may need to be considered for public health strategies that aim to change gun ownership in the USA.


  • Venlafaxine in management of hot flashes in women with breast cancer: a systematic review and meta-analysis

    by Ramya Ramaswami, Marcos Daniel Villarreal, Dina Marie Pitta, Janet S. Carpenter, Justin Stebbing, Bindu Kalesan

    Toxicity due to treatment causes a negative impact on quality of life in breast cancer survivors. Hot flash symptoms, described as intense sensations of heat, sweating and flushing occur in more than 50 % of breast cancer patients taking tamoxifen. We hypothesized that venlafaxine, a selective-norepinephrine reuptake inhibitor drug, was effective for reducing patient-reported hot flash scores among women treated for breast cancer compared to other non-hormonal treatments. We searched Medline, Scopus, and Cochrane Central Register of Controlled Trials from inception till May 2015 for venlafaxine (75 mg once daily or greater) with non-hormonal comparators for the treatment of hot flashes in female breast cancer patients. The primary outcome was hot flash score (derived from patient-reported hot flash severity and frequency) in randomized controlled trials. Standardized mean differences (SMD) were calculated for each study due to variation in the outcome measures. Heterogeneity was determined using I 2 statistics, and publication bias was assessed using a contour funnel plot and Egger’s tests. Pooled analyses demonstrated that venlafaxine significantly reduced hot flash scores compared to the trial comparators (overall SMD 2.06; 95 % confidence interval (CI) [0.40, 3.72]). There was significant heterogeneity among these studies (I 2 = 98.7 %, P < 0.001). Asymmetry in the contour funnel plot suggests the presence of publication bias and a trend towards small study effects (Egger’s test, P = 0.096). Venlafaxine is efficacious in managing hot flashes among women with breast cancer. This review highlights methodological issues that arise from eligible trials and recommends a collaborative approach in survivorship studies.
