Development and feasibility of randomized trial to reduce urinary bisphenols in women with obesity.

ABSTRACT:

Background

Bisphenol exposure is widespread and correlated with diabetes and cardiovascular disease. Previous intervention studies have successfully lowered bisphenol exposure among women of normal weight. The primary objective of this study was to develop and test the feasibility of a 3-week behavioral change intervention, rooted in social cognitive theory, to lower a broad range of bisphenols (BPA, BPS, and BPF) in women with obesity.

Methods

Thirty women with obesity (31.1 ± 5.6?kg/m², 21.1 ± 3.1?years) were randomly assigned to an intervention or control. The intervention included weekly face-to-face meetings to reduce bisphenol exposures from food, cosmetics, and packaged products. Fasting urinary bisphenols, creatinine, and weight were assessed at study entry and after 3 weeks.

Results

The intervention was evaluated as feasible (100% of enrollment and recruitment, 96% of retention and attendance at lesson plan visits, and 96% of a collection of urine samples). Adherence to the intervention was estimated based on completion of self-monitoring records; the number of daily records completed was 7.7 ± 1.3 (mean ± SD) after week 1, 7.1 ± 1.5 after week 2, and 4.4 ± 0.9 after week 3. In secondary analysis, there was a significant treatment × time effect on creatinine-corrected urinary BPS (- 1.42??g/g creatinine in the intervention vs. - 0.09??g/g creatinine in the control group).

Conclusion

In women with obesity, the 3-week intervention was considered feasible with promising preliminary results of decreasing BPS concentrations. These data warrant future large-scale clinical trial interventions to reduce bisphenol exposure and determine whether reductions in bisphenols positively impact diabetes and cardiovascular disease risk markers. This study was retroactively registered at ClinicalTrial.gov Identifier NCT03440307.

Project description:Background:About 1 in every 150 pregnancies end in stillbirth. Consequences include symptoms of post traumatic stress disorder (PTSD), depression, and anxiety. Yoga has been used to treat PTSD in other populations and may improve health outcomes for stillbirth mothers. The purpose of this study was to determine: (a) feasibility of a 12-week home-based, online yoga intervention with varying doses; (b) acceptability of a "stretch and tone" control group; and (c) preliminary efficacy of the intervention on reducing symptoms of PTSD, anxiety, depression, perinatal grief, self-compassion, emotional regulation, mindfulness, sleep quality, and subjective health.Methods:Participants (N = 90) were recruited nationally and randomized into one of three groups for yoga or exercise (low dose (LD), 60 min per week; moderate dose (MD), 150 min per week; and stretch-and-tone control group (STC)). Baseline and post-intervention surveys measured main outcomes (listed above). Frequency analyses were used to determine feasibility. Repeated measures ANCOVA were used to determine preliminary efficacy. Multiple regression analyses were used to determine a dose-response relationship between minutes of yoga and each outcome variable.Results:Over half of participants completed the intervention (n = 48/90). Benchmarks (≥70% reported > 75% satisfaction) were met in each group for satisfaction and enjoyment. Participants meeting benchmarks (completing > 90% of prescribed minutes 9/12 weeks) for LD and MD groups were 44% (n = 8/18) and 6% (n = 1/16), respectively. LD and MD groups averaged 44.0 and 77.3 min per week of yoga, respectively. The MD group reported that 150 prescribed minutes per week of yoga was too much. There were significant decreases in PTSD and depression, and improvements in self-rated health at post-intervention for both intervention groups. There was a significant difference in depression scores (p = .036) and grief intensity (p = .009) between the MD and STC groups. PTSD showed non-significant decreases of 43% and 56% at post-intervention in LD and MD groups, respectively (22% decrease in control).Conclusions:This was the first study to determine the feasibility and preliminary efficacy of an online yoga intervention for women after stillbirth. Future research warrants a randomized controlled trial.Trial registration:ClinicalTrials.gov. NCT02925481. Registered 10-04-16.

Project description:BackgroundUnhealthy infant feeding practices, such as a combination of formula feeding and early introduction of solids may lead to rapid or excessive weight gain in early infancy. Adolescent mothers' feeding behaviors are most directly related to infant weight gain in the first year of life. Compared to adult mothers, adolescent mothers are less knowledgeable, less responsive, more controlling, and less skilled in infant feeding, which interferes with infants' healthy growth. The Tools for Teen Moms trial aims to compare the effect of a social media intervention for low-income adolescent, first-time mothers of infants 2 months of age or younger, versus standard care on infant weight, maternal responsiveness, and feeding style and practices. The intervention is conducted during the infant's first four months of life to promote healthy transition to solids during their first year. Tools for Teen Moms is an intervention delivered via a social media platform that actively engages and coaches low-income adolescent mothers in infant-centered feeding to reduce rapid/excessive infant weight gain in the first six months of life.Methods/designWe describe our study protocol for a randomized control trial with an anticipated sample of 100 low-income African- American and Caucasian adolescent, first-time mothers of infants. Participants are recruited through Maternal-Infant Health Programs in four counties in Michigan, USA. Participants are randomly assigned to the intervention or the control group. The intervention provides infant feeding information to mothers via a web-based application, and includes daily behavioral challenges, text message reminders, discussion forums, and website information as a comprehensive social media strategy over 6 weeks. Participants continue to receive usual care during the intervention. Main maternal outcomes include: (a) maternal responsiveness, (b) feeding style, and (c) feeding practices. The primary infant outcome is infant weight. Data collection occurs at baseline, and when the baby is 3 and 6 months old.DiscussionExpected outcomes will address the effectiveness of the social media intervention in helping teen mothers develop healthy infant feeding practices that contribute to reducing the risk of early onset childhood obesity.Trial registrationClinical Trials.Gov NCT02244424, June 24, 2014.

Project description:ImportanceElectroacupuncture involving the lumbosacral region may be effective for women with stress urinary incontinence (SUI), but evidence is limited.ObjectiveTo assess the effect of electroacupuncture vs sham electroacupuncture for women with SUI.Design, setting, and participantsMulticenter, randomized clinical trial conducted at 12 hospitals in China and enrolling 504 women with SUI between October 2013 and May 2015, with data collection completed in December 2015.InterventionsParticipants were randomly assigned (1:1) to receive 18 sessions (over 6 weeks) of electroacupuncture involving the lumbosacral region (n = 252) or sham electroacupuncture (n = 252) with no skin penetration on sham acupoints.Main outcomes and measuresThe primary outcome was change from baseline to week 6 in the amount of urine leakage, measured by the 1-hour pad test. Secondary outcomes included mean 72-hour urinary incontinence episodes measured by a 72-hour bladder diary (72-hour incontinence episodes).ResultsAmong the 504 randomized participants (mean [SD] age, 55.3 [8.4] years), 482 completed the study. Mean urine leakage at baseline was 18.4 g for the electroacupuncture group and 19.1 g for the sham electroacupuncture group. Mean 72-hour incontinence episodes were 7.9 for the electroacupuncture group and 7.7 for the sham electroacupuncture group. At week 6, the electroacupuncture group had greater decrease in mean urine leakage (-9.9 g) than the sham electroacupuncture group (-2.6 g) with a mean difference of 7.4 g (95% CI, 4.8 to 10.0; P < .001). During some time periods, the change in the mean 72-hour incontinence episodes from baseline was greater with electroacupuncture than sham electroacupuncture with between-group differences of 1.0 episode in weeks 1 to 6 (95% CI, 0.2-1.7; P = .01), 2.0 episodes in weeks 15 to 18 (95% CI, 1.3-2.7; P < .001), and 2.1 episodes in weeks 27 to 30 (95% CI, 1.3-2.8; P < .001). The incidence of treatment-related adverse events was 1.6% in the electroacupuncture group and 2.0% in the sham electroacupuncture group, and all events were classified as mild.Conclusions and relevanceAmong women with stress urinary incontinence, treatment with electroacupuncture involving the lumbosacral region, compared with sham electroacupuncture, resulted in less urine leakage after 6 weeks. Further research is needed to understand long-term efficacy and the mechanism of action of this intervention.Trial registrationclinicaltrials.gov Identifier: NCT01784172.

Project description:BackgroundUrgency urinary incontinence afflicts many adults, and most commonly affects women. Medications, a standard treatment, may be poorly tolerated, with poor adherence. This warrants investigation of alternative interventions. Mind-body therapies such as hypnotherapy may offer additional treatment options for individuals with urgency urinary incontinence.ObjectiveTo evaluate hypnotherapy's efficacy compared to medications in treating women with urgency urinary incontinence.Materials and methodsThis investigator-masked, noninferiority trial compared hypnotherapy to medications at an academic center in the southwestern United States, and randomized women with non-neurogenic urgency urinary incontinence to weekly hypnotherapy sessions for 2 months (and continued self-hypnosis thereafter) or to medication and weekly counseling for 2 months (and medication alone thereafter). The primary outcome was the between-group comparison of percent change in urgency incontinence on a 3-day bladder diary at 2 months. Important secondary outcomes were between-group comparisons of percent change in urgency incontinence at 6 and 12 months. Outcomes were analyzed based on noninferiority margins of 5% for between group differences (P < 0.025) (that is, for between group difference in percentage change in urgency incontinence, if the lower bound of the 95% confidence interval was greater than -5%, noninferiority would be proved).ResultsA total of 152 women were randomized to treatment between April 2013 and October 2016. Of these women, 142 (70 hypnotherapy, 72 medications) had 3-day diary information at 2 months and were included in the primary outcome analysis. Secondary outcomes were analyzed for women with diary data at the 6-month and then 12-month time points (138 women [67 hypnotherapy, 71 medications] at 6 months, 140 women [69 hypnotherapy, 71 medications] at 12 months. There were no differences between groups' urgency incontinence episodes at baseline: median (quartile 1, quartile 3) for hypnotherapy was 8 (4, 14) and medication was 7 (4, 11) (P = .165). For the primary outcome, although both interventions showed improvement, hypnotherapy did not prove noninferior to medication at 2 months. Hypnotherapy's median percent improvement was 73.0% (95% confidence interval, 60.0-88˖9%), whereas medication's improvement was 88.6% (95% confidence interval, 78.6-100.0%). The median difference in percent change between groups was 0% (95% confidence interval, -16.7% to 0.0%); because the lower margin of the confidence interval did not meet the predetermined noninferiority margin of greater than -5%, hypnotherapy did not prove noninferior to medication. In contrast, hypnotherapy was noninferior to medication for the secondary outcomes at 6 months (hypnotherapy, 85.7% improvement, 95% confidence interval, 75.0-100%; medications, 83.3% improvement, 95% confidence interval, 64.7-100%; median difference in percent change between groups of 0%, 95% confidence interval, 0.0-6.7%) and 12 months (hypnotherapy, 85.7% improvement, 95% confidence interval, 66.7-94.4%; medications, 80% improvement, 95% confidence interval, 54.5-100%; median difference in percent change between groups of 0%, 95% confidence interval, -4.2% to -9.5%).ConclusionBoth hypnotherapy and medications were associated with substantially improved urgency urinary incontinence at all follow-up. The study did not prove the noninferiority of hypnotherapy compared to medications at 2 months, the study's primary outcome. Hypnotherapy proved noninferior to medications at longer-term follow-up of 6 and 12 months. Hypnotherapy is a promising, alternative treatment for women with UUI.

Project description:ObjectivesTo determine the feasibility of conducting a randomised trial of the effectiveness of cranberry extract in reducing antibiotic use by women with symptoms of acute, uncomplicated urinary tract infection (UTI).DesignOpen-label feasibility randomised parallel group trial.SettingFour general practices in Oxfordshire.ParticipantsWomen aged 18 years and above presenting to general practice with symptoms of acute, uncomplicated UTI.InterventionsWomen were randomly assigned using Research Electronic Data Capture in a 1:1:1 ratio to: (1) immediate antibiotics alone (n=15); (2) immediate antibiotics and immediate cranberry capsules for up to 7 days (n=15); or (3) immediate cranberry capsules and delayed antibiotics for self-initiation in case of non-improvement or worsening of symptoms (n=16).Primary and secondary outcome measuresThe primary outcome measures were: rate of recruitment of participants; numbers lost to follow-up; proportion of electronic diaries completed by participants; and acceptability of the intervention and study procedures to participants and recruiters. Secondary outcomes included an exploration of differences in symptom burden and antibiotic use between groups.ResultsFour general practitioner practices (100%) were opened and recruited participants between 1 July and 2 December 2019, with nine study participants recruited per month on average. 68.7% (46/67) of eligible participants were randomised (target 45) with a mean age of 48.4 years (SD 19.9, range 18-81). 89.1% (41/46) of diaries contained some participant entered data and 69.6% (32/46) were fully complete. Three participants (6.5%) were lost to follow-up and two (4.4%) withdrew. Of women randomly assigned to take antibiotics alone (controls), one-third of respondents reported consuming cranberry products (33.3%, 4/12). There were no serious adverse events.ConclusionsIt appears feasible to conduct a randomised trial of the use of cranberry extract in the treatment of acute, uncomplicated UTI in general practice.Trial registration numberISRCTN Registry (ID: 10399299).

Project description:BackgroundStress urinary incontinence (SUI) presents as unintentional urine leakage associated with activities. It significantly affects quality of life (QoL) and is the most common type of incontinence in women. Current treatment options, particularly non-surgical therapies, are lacking.ObjectiveTo assess the efficacy of mechanotherapy provided by the Flyte® intra-vaginal device during pelvic floor muscle training (PFMT).DesignThis was a randomized, controlled, double-blinded trial.Materials and methodsFlyte is a repeat use device for conditioning and strengthening the pelvic floor muscles (PFMs). It provides two-part mechanotherapy. Part 1 is the stretching and preloading of the PFM from the internal wand. Part 2 integrates mechanical pulses which elicit muscle cellular and tissue level responses that trigger cellular regeneration, improve neuromuscular facilitation and motor learning. Subjects used the device for 5 min/day for 12 weeks. Subjects (144) were randomized and evaluated at 6 and 12 weeks. Arm A (72) received both Part 1 and Part 2 mechanotherapy for 12 weeks, whereas Arm B (72) received Part 1 therapy for 6 weeks, then crossed over to full therapy. Mean age was 50, 49, respectively, prior pelvic/abdominal surgery 26%, 46%, and previous incontinence treatments 13%, 22%. The primary endpoint was 24-h pad weight (24-HR PW) at 6 weeks. Secondary endpoints were 24-HR PW at 12 weeks and QoL [International Consultation on Incontinence Questionnaire (ICIQ), Urinary Incontinence Quality of Life (IQOL)].ResultsPart 1 therapy had a greater than anticipated therapeutic effect. Thus, the study was underpowered to identify differences between study arms. Therefore, data were pooled to assess the effects of mechanotherapy. Twenty four-HR PW was significantly reduced at 6 weeks (p = <0.0001), with further reduction from 6 to 12 weeks (p = <0.0001). Data were stratified based on 24-HR PW severity. Significant reductions were noted in all severity groups (mild p = <0.0001, moderate p = <0.0001, severe p = <0.01). QoL was similarly improved at 6 weeks (ICIQ p = <0.0001, IQOL p = <0.0001), and 12 weeks (ICIQ p = <0.0001, IQOL p = <0.0001). Compliance was >80% at 6 weeks and 70% at 12 weeks.ConclusionTwo-part mechanotherapy significantly improved 24-HR PW and QoL across all severities of SUI. Improvements were noted in as little as 2 weeks and appeared to be sustained through 2-year follow up.Trial registrationRegistered on ClinTrials.gov (NCT02954042).
