Pilot Social Network Weight Loss Intervention With Two Immigrant Populations During the COVID-19 Pandemic.
American journal of health promotion : AJHP. 2022;(3):458-471
PURPOSE To examine the feasibility and acceptability of a social network weight loss intervention delivered by lay health promoters (HPs) to immigrant populations. DESIGN Single-arm, non-randomized, pilot study of a social network weight loss intervention developed by a community-based participatory research partnership and delivered by HPs. SETTING Community-based setting in Southeastern Minnesota, United States. SAMPLE Somali and Hispanic immigrants to the United States: 4 social networks of adults (2 Hispanic and 2 Somali) with 39 network participants. INTERVENTION Twelve-week behavioral weight loss intervention delivered by HPs (4 weeks in-person and then 8 weeks virtual). MEASURES Feasibility was assessed by recruitment and retention rates. Acceptability was assessed by surveys and focus groups with HPs and participants. Behavioral measures included servings of fruits and vegetables, drinking soda, and physical activity. Physiologic measures included weight, blood pressure, glucose, cholesterol, and triglycerides. ANALYSIS Paired t-tests of pre- to post-intervention changes at the end of 12 weeks of treatment. RESULTS Recruitment was feasible and post-intervention was 100%. Participants highly rated the intervention on satisfaction, motivation, and confidence to eat a healthy diet, be physically active, and lose weight. Participants were motivated by group social support and cohesion of their social networks. On average, participants lost weight (91.6 ± 15.9 to 89.7 ± 16.6 kg, P < .0001), lowered their systolic blood pressure (133.9±16.9 to 127.2 ± 15.8 mm Hg; P < .001), lowered their diastolic blood pressure (81 ± 9.5 to 75.8 ± 9.6 mm Hg; P < .0001), had more servings of vegetables per day (1.9 ± 1.2 to 2.6 ± 1.4; P < .001), and increased their physical activity (2690 ± 3231 to 6595 ± 7322 MET-minutes per week; P = .02). CONCLUSION This pilot study of 2 immigrant communities who participated in a peer-led weight loss social network intervention delivered during the COVID-19 pandemic demonstrated high feasibility and acceptability. Participants lost weight, improved their health status, and improved their health behaviors.
Chemotherapy-induced nausea and vomiting: incidence and characteristics of persistent symptoms and future directions NCCTG N08C3 (Alliance).
Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer. 2016;(6):2661-7
BACKGROUND Despite newer agents, chemotherapy-induced nausea and vomiting (CINV) continues to remain a distressing side effect to a proportion of patients undergoing systemic anti-cancer therapy. METHODS We recently performed an unplanned secondary analysis on a previously reported negative phase III trial (N08C3) looking at the efficacy of gabapentin/placebo in combination with dexamethasone and a 5HT3 receptor antagonist in the prevention of CINV for 413 patients undergoing regimens with highly emetogenic chemotherapy (HEC). In the current study, we attempted to better understand the higher than expected rate of overall patient satisfaction, despite a low complete response rate in both arms. Additionally, we looked at patient variables and their relationship to rates of CINV. RESULTS Approximately one third of patients experienced more than mild nausea and reported scores on the Functional Living Index-Emesis that indicated interference with activities. Thirty-five percent reported nausea greater than 2.5 on a scale of 0 to 10 (0 being none), 19 % reported at least one emetic episode, and 49 % reported taking rescue medication. Nausea and vomiting on day 1, cisplatin therapy, and history of motion sickness significantly predicted delayed CINV. Age, combination chemotherapy (HEC with moderately emetogenic), and getting treatment for breast cancer predicted CINV on day 1. DISCUSSION These data confirm previous reports that subgroups of patients may be more prone to acute and delayed CINV. Future CINV study design may benefit from a more individualized approach to CINV management, targeting those patients who are truly at risk for CINV despite continued drug development efforts.
A phase II trial of green tea in the treatment of patients with androgen independent metastatic prostate carcinoma.
BACKGROUND Recent laboratory and epidemiologic studies have suggested that green tea has antitumor effects in patients with prostate carcinoma. This Phase II trial explored green tea's antineoplastic effects in patients with androgen independent prostate carcinoma. METHODS This study, which was conducted by the North Central Cancer Treatment Group, evaluated 42 patients who were asymptomatic and had manifested, progressive prostate specific antigen (PSA) elevation with hormone therapy. Continued use of luteinizing hormone-releasing hormone agonist was permitted; however, patients were ineligible if they had received other treatments for their disease in the preceding 4 weeks or if they had received a long-acting antiandrogen therapy in the preceding 6 weeks. Patients were instructed to take 6 grams of green tea per day orally in 6 divided doses. Each dose contained 100 calories and 46 mg of caffeine. Patients were monitored monthly for response and toxicity. RESULTS Tumor response, defined as a decline ≥ 50% in the baseline PSA value, occurred in a single patient, or 2% of the cohort (95% confidence interval, 1-14%). This one response was not sustained beyond 2 months. At the end of the first month, the median change in the PSA value from baseline for the cohort increased by 43%. Green tea toxicity, usually Grade 1 or 2, occurred in 69% of patients and included nausea, emesis, insomnia, fatigue, diarrhea, abdominal pain, and confusion. However, six episodes of Grade 3 toxicity and one episode of Grade 4 toxicity also occurred, with the latter manifesting as severe confusion. CONCLUSIONS Green tea carries limited antineoplastic activity, as defined by a decline in PSA levels, among patients with androgen independent prostate carcinoma.
