Sex disparities in physical activity domains and hypertension prevalence.

BACKGROUND: This study aimed to examine the associations of leisure time physical activity (LTPA) and occupational physical activity (OPA) with the prevalence of hypertension, while exploring the sex disparities in these associations. METHODS: A cross-sectional study was conducted using data from the Korea National Health and Nutrition Examination Survey between 2014 and 2019 (n = 26,534). Hypertension was defined as the use of antihypertensive drugs or systolic and diastolic blood pressure ≥ 140/90 mm Hg. Self-reported physical activity (PA), assessed by the global PA questionnaire, was categorized into three domains: total PA, LTPA and OPA. Each PA domain was classified based on METs-min/wk and intensity. RESULTS: In a multivariable adjusted model, the odds ratio (OR) with 95% confidence intervals (CIs) for the prevalence of hypertension in the active versus inactive group, based on METs, was 0.92 (95% CI 0.85-0.99) for total PA, 0.90 (95% CI 0.83-0.98) for LTPA and 1.21 (95% CI 1.05-1.38) for OPA. Compared to the inactive group, moderate to vigorous intensity was associated with a lower odds of hypertension for total PA and LTPA (total PA: OR 0.95, 95% CI 0.89-1.00 and LTPA: OR 0.92, 95% CI 0.86-0.98), but a higher odd for OPA (OR 1.17, 95% CI 1.05-1.30). Subgroup analyses showed significant evidence of effect modification by sex on the associations of total PA and LTPA (METs and intensity) with hypertension prevalence (p-values for interaction < 0.01); the associations were generally stronger for women. OPA was associated with a higher prevalence of hypertension in women, but not in men (p-value for interaction > 0.05). CONCLUSIONS: Higher levels of total PA and LTPA were associated with lower prevalence of hypertension in both men and women, with slightly stronger associations for women. However, higher OPA was associated with a higher prevalence of hypertension in women. These findings support the PA health paradox hypothesis and highlight the sex disparities in the association between OPA and hypertension prevalence.

Current Trends in the Use of Social Media by Plastic Surgeons.

BACKGROUND: As social media continue to be widely used, understanding the current trend in social media use by plastic surgeons will help determine how the specialty can better harness its power and respect its risks. In this study, the authors performed a survey study of trainees, candidates, and members of the American Society of Plastic Surgeons to determine current use and consensus on social media in plastic surgery. METHODS: An electronic survey was sent to plastic surgery trainees, candidates, and members of the American Society of Plastic Surgeons using SurveyMonkey. Demographic data, social media use patterns, and views on social media use were collected. RESULTS: When compared with salaried surgeons, private practitioners used social media for the promotion of their practice, such as patient acquisition (74.3 percent versus 28.3 percent) and branding (61 percent versus 21.7 percent). The majority of nonusers felt social media was too time consuming and susceptible to breach of patient privacy. The majority of social media users agreed that acceptable use included before-and-after photographs, video testimonials, and patient reviews. Both social media users and nonusers alike agreed that plastic surgery residents should receive training on social media. CONCLUSIONS: This study showed that a majority of plastic surgeons use social media to brand their practice, attract patients, and educate the public. Without engaging in this valuable tool, plastic surgeons' voices will be lost in the conversation. To use social media to their greatest potential, this specialty needs to begin formal training in the proper and ethical use of social media.

A Primer on Social Media Use by Young Plastic Surgeons.

Similar to the outcry over the ethics of website marketing by physicians in the 1990s, the resistance to plastic surgeons' use of social media has been loud and vehement. Many physicians, although receptive to website marketing, view social media as too radical or unprofessional. Despite the controversy, the value of social media as a communication tool for interacting with and educating patients is supported by studies showing that 65 percent of Americans and 90 percent of young adults use social media. Many plastic surgeons have been early adopters, as reflected by the articles written to help board-certified plastic surgeons use social media in academic medicine and for their practice. However, there is little guidance for young plastic surgeons who wish to use social media for professional purposes. In this study, the authors discuss the ethics and current literature on social media use by young plastic surgeons and make recommendations for how to use social media during training and after residency graduation.

In vivo and in vitro assessment of the bleaching effectiveness of a brush-off patch containing 3.0% hydrogen peroxide.

OBJECTIVES: To evaluate the efficacy of a brush-off patch containing 3.0% hydrogen peroxide, which is a new over-the-counter (OTC) product for tooth whitening, and determine the optimal protocol for use. MATERIALS AND METHODS: We performed an in vitro study using hydroxyapatite specimens and a clinical trial involving 140 volunteers. The brush-off patch was applied to the specimens (in vitro) or the maxillary anterior teeth (in vivo; 14 days) for 10 min twice daily (case 10 group) or 30 min once daily (case 30 group). We also included control groups in both experiments. Lightness (L*), redness (a*), and yellowness (b*) values were measured using a colorimeter. In the in vivo study, color changes were measured at baseline and 7 and 14 days after the start of patch application. The overall color change (ΔE) was statistically analyzed. RESULTS: In the in vitro study, the color change (ΔE*) after the experiment was significantly different between the two case groups and the control group (p < 0.001). In the in vivo study, the case groups showed color changes at both 7 and 14 days after patch application. In particular, the change in the case 30 group was significantly more prominent on day 14 than on day 7 (p < 0.05). CONCLUSION: Our findings suggest that brush-off patches containing 3.0% hydrogen peroxide are effective OTC products for tooth whitening. CLINICAL RELEVANCE: For best results, brush-off patches containing 3.0% hydrogen peroxide can be applied once daily for 30 min.

Evaluation of the American Society of Anesthesiologists Physical Status classification system in risk assessment for plastic and reconstructive surgery patients.

BACKGROUND: The American Society of Anesthesiologists Physical Status (ASA-PS) classification is a ranking system that quantifies patient health before anesthesia and surgery. Some surgical disciplines apply the ASA-PS to gauge a patient's likelihood of developing postoperative complications. OBJECTIVE: In this study, the authors analyze whether ASA-PS scores can successfully predict risk for postoperative complications in plastic and reconstructive operations. METHODS: The authors retrospectively reviewed the charts of 1801 patient procedures and selected for inclusion 1794 complex plastic and reconstructive operations that took place at 1 of several academic medical institutions between January 2008 and January 2012. ASA-PS scores, patient comorbidities, and postoperative complications were analyzed. Percentile data were treated with tests for proportions. Nonpercentile data were analyzed through comparison of means (t test). Low-risk (ASA 1-2) and high-risk (ASA 3+) groups were compared with simple odds ratios. RESULTS: For the 1430 women and 364 men in the patient cohort (average age, 49.5 years), the overall complication rate was 27.7%. When patients with complications were compared to those without, body mass index, operation time, recent major surgery, diabetes, hypertension, renal disease, cancer, and oral contraceptive use were statistically significant. After high-risk (n = 398) and low-risk (n = 1396) groups were identified, infection, delayed wound healing, deep vein thrombosis, and overall complications had significantly increased incidence in the high risk group. Notably, deep vein thrombosis displayed the highest odds ratio (4.17) and a complication rate increase from 0.93% to 3.77%. CONCLUSIONS: ASA-PS scores can be used either as substitutes for or as adjuncts to questionnaire-based risk assessment methods in plastic surgery. In addition to deducing significant findings for deep vein thrombosis incidence, ASA-PS scores hold important predictive associations for multiple non-venous thromboembolism complications, providing a broader measurement for postoperative complication risks.
