Self-reported sleep quality and exercise in polycystic ovary syndrome: A secondary analysis of a pilot randomized controlled trial.

OBJECTIVE: To examine the proportion of participants with poor sleep quality, evaluate the associations between sleep quality and anthropometric and cardiometabolic health markers, and evaluate the effect of high intensity interval training (HIIT) and continuous aerobic exercise training (CAET) on sleep quality in polycystic ovary syndrome (PCOS). DESIGN: Secondary analysis of a pilot randomized controlled trial. PATIENTS: Women with PCOS aged 18-40 years. MEASUREMENTS: The Pittsburgh Sleep Quality Index (PSQI) was measured at baseline and following a 6-month exercise intervention. A PSQI score >5 indicates poor sleep. Linear regression was used to evaluate the associations between PSQI score and anthropometric and cardiometabolic health markers, and the effect of exercise training on these associations. RESULTS: Thirty-four participants completed the PSQI at baseline, and 29 postintervention: no-exercise control (n = 9), HIIT (n = 12) and CAET (n = 8). At baseline, 79% had poor sleep quality. Baseline PSQI score was positively correlated with body mass index, waist circumference, body weight, haemoglobin A1c and insulin resistance. Mean PSQI score changes were -0.4 (SD 1.1), -0.7 (SD 0.6) and -0.5 (SD 0.9) for control, HIIT and CAET, respectively. For HIIT participants, change in PSQI score was associated with changes in body weight (B = .27, 95% CI 0.10-0.45) and waist circumference (B = .09, 95% CI 0.02-0.17). CONCLUSION: Most participants had poor sleep quality which was associated with poorer anthropometric and cardiometabolic health markers. There were no statistically significant changes in PSQI score with exercise training. With HIIT training, decreases in the sleep efficiency score were associated with reductions in body weight and waist circumference. Further studies are needed to determine the effect of exercise training on sleep quality.

Exercise training and reproductive outcomes in women with polycystic ovary syndrome: A pilot randomized controlled trial.

OBJECTIVE: Exercise is recommended for polycystic ovary syndrome (PCOS), but the most effective exercise prescription is unclear. This trial compared effects of high-intensity interval training (HIIT), continuous aerobic exercise training (CAET) and no-exercise control on reproductive, anthropometric and cardiometabolic outcomes in PCOS. DESIGN: Pilot randomized controlled trial. PARTICIPANTS: Previously inactive women aged 18-40 years with PCOS. MEASUREMENTS: Feasibility outcomes included recruitment, retention, adherence to exercise and daily ovulation prediction kit (OPK) testing. Preliminary efficacy outcomes included reproductive, anthropometric and cardiometabolic health markers. RESULTS: Forty-seven women were randomized to no-exercise control (n = 17), HIIT (n = 16), or CAET (n = 14). Forty (85%) participants completed the trial. Median exercise adherence was 68% (IQR 53%, 86%). Median daily OPK-testing adherence in the first half of the intervention was 87% (IQR 61%, 97%) compared with 65% (IQR 0%, 96%) in the second half. Body mass index decreased significantly in CAET compared with control (-1.0 kg/m2 , p = .01) and HIIT (-0.9 kg/m2 , p = .04). Mean waist circumference decreased in all groups (-7.3 cm, -6.9 cm, -4.5 cm in HIIT, CAET and control) with no significant between-group differences. Mean LDL-C was significantly reduced for HIIT compared to CAET (-0.33 mmol/L, p = .03). HDL-C increased in HIIT compared with control (0.18 mmol/L, p = .04). CONCLUSIONS: There were feasibility challenges with adherence to daily ovulation assessment limiting the ability to analyse the effect of the exercise interventions on ovulation. CAET and HIIT were both effective at improving anthropometrics and some cardiometabolic health markers. Further studies need to determine optimal and acceptable exercise prescriptions for this population.

Sex Differences in Endovascular Treatment for Stroke: A Population-based Analysis.

BACKGROUND: Acute ischemic stroke may affect women and men differently. We aimed to evaluate sex differences in outcomes of endovascular treatment (EVT) for ischemic stroke due to large vessel occlusion in a population-based study in Alberta, Canada. METHODS AND RESULTS: Over a 3-year period (April 2015-March 2018), 576 patients fit the inclusion criteria of our study and constituted the EVT group of our analysis. The medical treatment group of the ESCAPE trial had 150 patients. Thus, our total sample size was 726. We captured outcomes in clinical routine using administrative data and a linked database methodology. The primary outcome of our study was home-time. Home-time refers to the number of days that the patient was back at their premorbid living situation without an increase in the level of care within 90 days of the index stroke event. In adjusted analysis, EVT was associated with an increase of 90-day home-time by an average of 6.08 (95% CI -2.74-14.89, p-value 0.177) days in women compared to an average of 11.20 (95% CI 1.94-20.46, p-value 0.018) days in men. Further analysis revealed that the association between EVT and 90-day home-time in women was confounded by age and onset-to-treatment time. CONCLUSIONS: We found a nonsignificant nominal reduction of 90-day home-time gain for women compared to men in this province-wide population-based study of EVT for large vessel occlusion, which was only partially explained by confounding.

Comparative Success of Recruitment Strategies for an Exercise Intervention Trial Among Women With Polycystic Ovary Syndrome: Observational Study.

BACKGROUND: Effective and efficient participant recruitment is a key determinant of the success of a research program. Previously reported recruitment strategies have displayed variable success rates in studies on women with polycystic ovary syndrome (PCOS). OBJECTIVE: This study aimed to evaluate the effectiveness and cost per participant of the recruitment strategies that we used in a prospective randomized controlled trial to examine the effects of exercise training among inactive women with PCOS, who are aged 18-40 years. METHODS: The 4 recruitment methods we used were as follows: (1) referral by health care providers or by word of mouth, (2) media (eg, local newspaper stories and radio interviews), (3) Facebook advertisements, and (4) unpaid advertisements including posters and websites. The proportions of potential, eligible, and enrolled participants recruited with each method were determined and compared using tests of proportion. The time investment and cost per participant enrolled were calculated for each recruitment strategy. RESULTS: Of 200 potential participants screened, 98 (49%) were recruited from unpaid advertisements (posters and websites), 70 (35%) from Facebook advertisements, 16 (8%) by referral, and 16 (8%) from traditional media (newspaper and radio). Every potential participant was recruited from separate means (ie, no participant was approached through more than one recruitment method). A total of 109 (54.5%) women were deemed eligible for participation in the trial, and 60 (30.0%) were enrolled. The proportion of potential participants who completed the trial was higher for those recruited from traditional media than from Facebook advertisements (n=7/16, 44% vs n=13/70, 19%, respectively; P=.03) or unpaid advertisements (n=7/16, 44% vs n=13/98, 13%, respectively; P=.002). The cost per participant was Can $18.21 (US $14.46) for Facebook advertisements and Can $43.88 (US $34.85) for unpaid advertisements. There were no direct trial costs for referrals or traditional media. CONCLUSIONS: For this trial, each method was important for recruiting inactive women with PCOS because no participant reported learning about the trial through more than one method. Unpaid advertisements and Facebook advertisements helped recruit the largest number of participants in the trial, the former resulting in a higher cost per participant than the latter.

Sexual Activity After Acute Coronary Syndrome: A Qualitative Approach to Patient and Partner Experiences.

BACKGROUND: Little is known about how best to support both patients and their partners in the reengagement of sexual activity (SA) after acute coronary syndrome (ACS), with sparse direct data from the partner on their needs and concerns in the area of SA support. OBJECTIVES: We undertook a qualitative study to address this gap in the literature through 3 objectives from a patient and partner perspective: (1) to characterize the experience of reengaging in SA post ACS, (2) to identify needs and priorities in the area of SA support post ACS, and (3) to determine whether cardiac rehabilitation (CR) could be an acceptable point of intervention for SA support. METHODS: Semistructured qualitative interviews were conducted with 6 male patients who were post ACS and their partners (age range, 47-81 years). Patients were criterion sampled from the Alberta Provincial Project for Outcome Assessment in Coronary Heart Disease database. Inductive thematic data analysis was conducted. RESULTS: Four themes were identified: "importance," "support received," "on their own," and "wanting support." Couples reaffirmed the importance of SA pre and post ACS, reported SA support as currently insufficient but articulated ways it could be improved, and reported CR as a current source of SA support but thought there could be room for improvement on the content and delivery of such information. CONCLUSIONS: This study illustrates the potential value of promoting SA support for both patients who are post ACS and their partners and reports that SA support provided at CR would be viewed as important, needed, and acceptable.

Skin cancer knowledge and photoprotective practices of organ transplant recipients.

BACKGROUND: Long-term use of immunosuppressive medications by organ transplant recipients (OTRs) leads to an increased risk of non-melanoma skin cancers (NMSCs). The objective of this study was to assess photoprotective knowledge and practices among OTRs and to identify predictors of poor sunscreen adherence and barriers to photoprotection. METHODS: A written survey was administered to 300 solid OTRs attending the Southern Alberta Transplant Program. Demographics, transplant and NMSC history, ultraviolet radiation (UVR) exposure, photoprotective knowledge and practices, and barriers to implementing photoprotection were collected. Relevant statistical analyses and univariate and multivariable regression models on sunscreen use were performed. RESULTS: One hundred and seventy-nine of the 300 respondents reported not using sunscreen most days despite 79.3% recalling have received photoprotection education. Of the surveyed OTRs, 45.7% reported no barriers to implementing photoprotective practices. On average, respondents scored 74.5% on a commonly used tool to assess photoprotective knowledge (SD 30.6%). In multivariable analyses, older age, male gender, and lack of post-secondary education were associated with lower rates of self-reported sunscreen use. The most commonly patient-reported barriers to photoprotection were "hassle/time consuming" (16.7%) and "sunscreen is uncomfortable or unpleasant" (10.0%). CONCLUSIONS: Despite OTRs self-reporting having received sufficient sun-protective knowledge and demonstrating reasonable recollection of photoprotective education on assessment, implementation of sun protection in the studied OTRs remains suboptimal.

Proceedings from the 9th Annual University of Calgary Leaders in Medicine Research Symposium.

On November 3, 2017 the Leaders in Medicine (LIM) program at the University of Calgary's Cumming School of Medicine hosted the 9th Annual Leaders in Medicine (LIM) Symposium. This year's event commemorated 20 years of the LIM program and its dedication to the training of clinician- scientists.

The Need for an Executive Leadership Curriculum in Scientist-Clinician Training Programs.

The health of Canadians depends on effective leadership among health care providers to facilitate the translation of new health discoveries into clinical practice. Clinician-scientists play an important role in bridging the gap between research and clinical practice, and require effective leadership skills to advance clinical practice successfully. To accelerate the leadership development in clinician scientist trainees, with the aim of developing strong leaders in administration and health advocacy, the Leaders in Medicine (LIM) training program at the University of Calgary created an Executive Leadership Coaching Program involving three phases: 1) an evidence-based evaluation tool, the Core Values IndexTM (CVI), that was used to identify the key drivers behind how individuals can be most effective in making their contribution; 2) small group workshops to debrief the results of the CVI assessment; and 3) one-on-one executive coaching sessions to facilitate the discovery, development and deployment of individual leadership capabilities. Coaching in leadership strategies enables clinician-scientist trainees to lead, influence, manage and deliver science-based improvements into the practice of medicine. We strongly recommend that other Canadian scientist-clinician training programs consider opportunities like the ones we offer to our LIM trainees. This training has important implications for the delivery of healthcare in Canada.
