ABSTRACT
BACKGROUND: Alcohol consumption is more prevalent among sexual minorities than among heterosexuals; however, differences between minority sexual orientation groups are understudied. This systematic review and meta-analysis aimed to summarize existing evidence on the prevalence of alcohol use among bisexual people compared to their lesbian/gay and heterosexual counterparts. METHODS: A systematic review of literature from 1995 to May 2020 was performed using Medline, PsycInfo, and Embase (OVID), Scopus, CINHAL and LGBT Life (EBSCO), combining keywords for bisexuality and alcohol use. Peer-reviewed publications that reported quantitative data on alcohol use among bisexual people were included. A random-effects model was used to pool the prevalence of two outcomes: any alcohol use and heavy episodic drinking (HED). Subgroup analysis and random-effects meta-regression were used to explore heterogeneity. RESULTS: Of 105 studies eligible for data extraction, the overall prevalence of alcohol use was higher among bisexuals compared to lesbian/gay and heterosexual people. For example, the prevalence of past-month HED was 30.0% (28.2, 31.8) among bisexual people versus 25.5% (23.8, 27.2) among lesbian/gay and 21.3% (19.6, 23.0) among heterosexual individuals. Pooled odds ratio estimates showed that bisexual people were more likely to report alcohol use and HED compared to their counterparts. Gender was a significant effect modifier in meta-regression analysis, with greater disparities among women than among men. CONCLUSIONS: These results highlight the need for additional research to understand factors underlying bisexual people's greater risk, and particularly bisexual women, as well as alcohol use interventions that are targeted towards the specific needs of bisexual people.

INTRODUCTION: Recent advances in small cell lung cancer (SCLC) treatments necessitate a better understanding of real-world health utility scores (HUS) in patients treated under current standards to facilitate robust pharmaco-economic assessments. METHODS: In this single institution cohort observational study, HUS were evaluated in patients with SCLC through EQ-5D questionnaires at outpatient visits (encounters). In addition, patients completed questionnaires relating to treatment toxicities and cancer symptoms. Clinical and pathological variables were abstracted from electronic medical records and disease status at each patient visit was documented. The impact of these variables on HUS were explored. RESULTS: There were 282 clinical encounters (12% newly diagnosed; 37% stable on treatment; 22% progressing on treatment; 29% stable off therapy/other) in 111 SCLC patients (58% male; 64% extensive stage (ES) SCLC). At the first encounter 29% of patients had an ECOG performance status (PS) ≥ 2. ES-SCLC, bone metastases, female sex, progressive disease and/or PS were each significantly associated with decreased HUS in multivariable analyses. Patients clinically stable on first line therapy had generally steady HUS longitudinally, with differences in HUS between limited disease (LD) and ES patients emerging as treatment progressed. Decreased HUS were associated with increased severity of the majority of measured symptoms (fatigue/tiredness, loss of appetite, pain, drowsiness, shortness of breath, anxiety, depression, and overall well-being; each p<0.001), supporting the value of EQ-5D-derived HUS in assessing health utility. CONCLUSION: Our HUS values in chemotherapy-treated SCLC are clinically relevant and are associated with specific clinico-demographic, symptom and toxicity factors.

BACKGROUND & PURPOSE: Prophylactic cranial irradiation (PCI) is recommended for limited-stage small-cell lung cancer (LS-SCLC) patients with good response to concurrent chemoradiation. We report our institution's 20-year experience with this patient population and associated clinical outcomes. MATERIALS & METHODS: A retrospective cohort of consecutive LS-SCLC patients treated with curative intent chemoradiation at our institution (1997-2018) was reviewed. Overall survival (OS) was calculated using the Kaplan-Meier method, and significant covariates determined by the Cox proportional hazards model. Covariates predictive of PCI were determined using Fisher's exact test and the Mann-Whitney test. Brain failure risk (BFR) was calculated using the cumulative incidence method treating death as a competing event. Treatment cohorts (historic vs. contemporary) were stratified by the median year of diagnosis (2005). RESULTS: A total of 369 patients with LS-SCLC were identified, of which 278 patients were notionally PCI eligible. PCI was given to 196 patients (71%). Younger age was associated with PCI utilization (p < 0.001). PCI utilization rates did not change between the historic and contemporary treatment era (p = 0.11), whereas magnetic resonance imaging (MRI) use at baseline and follow-up became more prevalent in the contemporary era (p = <0.001). On multivariable analysis, PCI utilization was associated with improved OS (HR 1.88, 95% CI 1.32-2.69) and decreased BFR (HR 4.66, 95% CI 2.58-8.40). Patients who had MRI follow-up had a higher incidence of BFR (HR 0.35, 95% CI 0.18-0.66) in multivariable analyses. CONCLUSIONS: For LS-SCLC patients at our institution, PCI is more frequently utilized in younger patients, and the utilization rate did not change significantly over the past 20 years. PCI was independently associated with improved OS and lower BFR. Omission of PCI in LS-SCLC patients should not be routinely practiced in the absence of further prospective data.
ABSTRACT
Cerebral concussion is a brain injury, that involves a complex pathophysiological process that affects the brain as a result of biomechanical forces. With the increasing prevalence, it is important that the public is knowledgeable about concussion and its symptoms, so that they can bring attention to individuals with concussion symptoms soon after onset, for appropriate care. The aim of this study was to determine the knowledgeability of young adults. Secondary aims were to compare the knowledgeability of young adults of different age, of different countries of residence, of different sex, and of different perceived knowledge about concussions. An online survey was circulated to young adults in Canada, the US and the UK. The survey consisted of three components - a consent form, respondent demographics and eight questions to assess each respondent's knowledgeability of concussions. The knowledgeability of each respondent was determined by the summation of the number of correct responses to the knowledge questions. A total of 307 respondents consented and completed the survey in its entirety. The mean knowledge score was 4.25 out of 8. None of the cohort analyses based on demographics - 19 years old and under vs. 20 years and older; North Americans vs. non-North Americans; females vs. males - suggested that one group was more knowledgeable than the other group. These results suggest that educational programs can be developed to increase awareness of concussions. As each cohort seems to have similar starting knowledge levels, it seems appropriate to develop a uniform program to first try to increase knowledgeability, and then produce specialised programs to raise knowledge of certain cohorts. However, prior to the establishment of programs, further studies should be conducted to verify the results disclosed herein.
