Understanding barriers and facilitators to lifestyle management in people with polycystic ovary syndrome: A mixed method systematic review.

Polycystic ovary syndrome (PCOS) is an endocrine disorder affecting 10-13% of reproductive-aged women. Lifestyle management through diet and physical activity changes can improve reproductive, metabolic, and psychological comorbidities. The aim of this systematic review is to understand the barriers and facilitators to lifestyle changes from the perspective of people with PCOS and health care professionals (HCP) using the theoretical domains framework and capability, opportunity, motivation, and behavior model. Six databases were systematically searched for qualitative, quantitative, and mixed-methods studies to 22nd September 2022. Quantitative outcomes from quantitative and mixed-methods studies were narratively synthesized and all studies were thematically analyzed. Sixty-eight papers met the eligibility criteria. HCP education on lifestyle management in PCOS was viewed by all to be inadequate, impacting the quality of care and health outcomes. Lifestyle advice delivered by a multidisciplinary team, including dietitians, was identified as a key component for change. All agreed that there was a need for individualized and PCOS-specific lifestyle advice. Weight stigma was identified as negatively impacting both those in larger and smaller bodies with PCOS, reducing the quality of care and affecting self-perception and mental health. People with PCOS perceived that lifestyle management was overly focused on weight loss and fertility, independent of their own personal motivations and goals. Systemic changes, including increasing HCP education on lifestyle management and multidisciplinary collaboration, focusing on lifestyle advice that meets individual needs, and reducing the use of weight-centric care are necessary for long-term sustainable changes and improvements in health outcomes in people with PCOS.

Effectiveness of naturopathy for pregnancy in women with diminished ovarian reserve: feasibility randomized controlled trial.

RESEARCH QUESTION: Is conducting a randomized control trial (RCT) to assess the effectiveness of whole-system naturopathy in improving pregnancy rates among women with diminished ovarian reserve (DOR) feasible? DESIGN: A two-arm, parallel group, assessor-blinded feasibility RCT was conducted. Women with DOR, trying to conceive naturally or by ART, were randomly assigned to naturopathy plus usual care, or usual care alone for 16 weeks. Primary outcomes were feasibility (recruitment, adherence, retention rates), acceptability and safety. Secondary outcomes included ongoing pregnancy rates, live birth rates and health-related outcomes (mental health, quality of life, diet, exercise, sleep and weight). Statistical significance of the differences between the two groups (P-values) were exploratory. RESULTS: One hundred and fifteen women completed the screening survey between March and November 2022. Of these, 66 women were assessed for eligibility and 41 (62%) consented. Recruitment resulted in seven enrolments each month. All 41 participants (100%) adhered to the intervention, 38 (93%) completed end-point questionnaires, 32 (78%) found study participation to be acceptable and 18 out of 21 (86%) from the intervention group would recommend a naturopathic intervention to other women with DOR. The naturopathic treatment was associated with only mild and temporary adverse events. No between-group differences were observed for pregnancy and live birth rates. CONCLUSION: The evaluation of whole-system naturopathy through a RCT was feasible and the treatment was acceptable and well tolerated according to women with DOR. Outcomes from this study will help inform sample size calculations powered for fertility outcomes for future RCTs on this topic.

The effectiveness and safety of lifestyle medicine and integrative therapies in inflammatory arthritis: an umbrella review using a hierarchical evidence gathering approach.

Objective: An umbrella review was conducted to provide a comprehensive evaluation of the evidence on lifestyle medicine and integrative therapies for inflammatory arthritis. Methods: Five electronic databases were searched for umbrella reviews, meta-analyses, and systematic reviews of randomised controlled trials on acupuncture, diet, exercise, herbal medicine, nutrient supplements, and mind-body therapies for rheumatoid arthritis, spondyloarthritis, and gout published from January 2012 to December 2022. The primary outcomes were functional status and quality of life. Quality assessment was performed using the A MeaSurement Tool to Assess systematic Reviews (AMSTAR-2) tool, and the certainty of evidence for our primary outcomes was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach where possible. Results: We included 52 reviews. Exercise was beneficial for functional status in both rheumatoid arthritis and spondyloarthritis, with moderate certainty of evidence. Chinese herbal medicine in combination with disease-modifying anti-rheumatic drugs may improve functional status in rheumatoid arthritis (very low certainty evidence). Acupuncture may improve functional status in rheumatoid arthritis and pain in both rheumatoid arthritis and gout; however, the evidence is of very low certainty. Evidence for other therapies was not clinically significant; however, it suggests possible benefits from quercetin and polyunsaturated fatty acids. Yoga may result in a moderate improvement in functional status when used as an adjunct to medication; however, the certainty of evidence is very low. Diet interventions offered inconsistent improvements to functional status in rheumatoid arthritis, spondyloarthritis, and gout with low to very low certainty. Conclusion: Exercise should be prescribed for people with rheumatoid arthritis and spondyloarthritis. More research is needed to confirm or refute evidence for Chinese herbal medicine, acupuncture, yoga, and anti-inflammatory diets.

Health needs, treatment decisions and experience of traditional complementary and integrative medicine use by women with diminished ovarian reserve: A cross-sectional survey.

BACKGROUND: Women with diminished ovarian reserve (DOR) have fewer eggs than would be expected at their age. It is estimated that 10% of women seeking fertility treatment are diagnosed with DOR. However, the success rate of medically assisted reproduction (MAR) is significantly lower in women with DOR, thus many seek additional approaches. AIM: To explore the health needs of women with DOR, treatment options and experience of treatment including traditional complementary integrative medicine (TCIM). METHODS: Anyone with a diagnosis of DOR, living in Australia or New Zealand, aged over 18 were invited to complete an online survey distributed via fertility support networks and social media platforms from April to December 2021. RESULTS: Data from 67 respondents were included. The main aspects of health that were impacted by DOR were fertility (91.0%) and mental health (52.2%). The main treatment recommended was MAR with most women either currently using MAR (38.8%) or having previously used MAR (37.3%). TCIM was widely used with 88.1% of women utilising supplements, 74.6% consulting with TCIM practitioners, and 65.7% adopting self-care practices. The main reasons for using TCIM were to improve fertility or support pregnancy, and to support general health and well-being. CONCLUSIONS: Women with DOR have additional health needs apart from infertility, most notably mental health support. The main form of treatment utilised is MAR, despite DOR being challenging for fertility clinicians. TCIM was widely used, and respondents perceived benefits related to improving fertility, supporting pregnancy, or improving well-being through use of acupuncture, meditation, naturopathy, massage, yoga.

Inositol for Polycystic Ovary Syndrome: A Systematic Review and Meta-analysis to Inform the 2023 Update of the International Evidence-based PCOS Guidelines.

CONTEXT: Insulin resistance is common in women with polycystic ovary syndrome (PCOS). Inositol may have insulin sensitizing effects; however, its efficacy in the management of PCOS remains indeterminate. OBJECTIVE: To inform the 2023 international evidence-based guidelines in PCOS, this systematic review and meta-analysis evaluated the efficacy of inositol, alone or in combination with other therapies, in the management of PCOS. DATA SOURCES: Medline, PsycInfo, EMBASE, All EBM, and CINAHL from inception until August 2022. STUDY SELECTION: Thirty trials (n = 2230; 1093 intervention, 1137 control), with 19 pooled in meta-analyses were included. DATA EXTRACTION: Data were extracted for hormonal, metabolic, lipids, psychological, anthropometric, reproductive outcomes, and adverse effects by 1 reviewer, independently verified by a second. DATA SYNTHESIS: Thirteen comparisons were assessed, with 3 in meta-analyses. Evidence suggests benefits for myo-inositol or D-chiro-inositol (DCI) for some metabolic measures and potential benefits from DCI for ovulation, but inositol may have no effect on other outcomes. Metformin may improve waist-hip ratio and hirsutism compared to inositol, but there is likely no difference for reproductive outcomes, and the evidence is very uncertain for body mass indexI. Myo-inositol likely causes fewer gastrointestinal adverse events compared with metformin; however, these are typically mild and self-limited. CONCLUSION: The evidence supporting the use of inositol in the management of PCOS is limited and inconclusive. Clinicians and their patients should consider the uncertainty of the evidence together with individual values and preferences when engaging in shared decision-making regarding the use of inositol for PCOS.

Efficacy of dietary supplements containing isolated organic compounds for weight loss: a systematic review and meta-analysis of randomised placebo-controlled trials.

BACKGROUND/OBJECTIVES: A systematic review with meta-analysis was conducted to synthesise evidence on the efficacy of dietary supplements containing isolated organic compounds for weight loss. SUBJECTS/METHODS: Four electronic databases (Medline, Embase, Web of Science, Cinahl) were searched until December 2019. Sixty-seven randomised placebo-controlled trials of dietary supplements containing isolated organic compounds for weight loss were included. Meta-analyses were conducted for chitosan, glucomannan, conjugated linoleic acid and fructans, comparing mean weight difference post-intervention between participants receiving the dietary supplement or placebo. RESULTS: Statistically significant weight differences compared to placebo were observed for chitosan (-1.84 kg; 95% confidence interval [CI] -2.79, -0.88; p < 0.01), glucomannan (-1.27 kg; 95%CI -2.45, -0.09; p = 0.04), and conjugated linoleic acid (-1.08 kg; 95%CI -1.61, -0.55; p < 0.01). None met our threshold for clinical significance (≥2.5 kg). There was no statistically significant effect on weight for fructans compared to placebo (p = 0.24). For dietary supplements with an inadequate number of trials for meta-analysis, a statistically and borderline clinically significant weight difference compared to placebo was found for modified cellulose, manno-oligosaccharides (in males), blood orange juice extract, and three multiple-ingredient dietary supplements. These were only reported in one trial of each. Thus, more evidence is needed before recommending them for weight loss. CONCLUSIONS: While some dietary supplements containing isolated organic compounds warrant further investigation to determine efficacy and safety, there is currently insufficient evidence to recommend any of these dietary supplements for weight loss.

Effectiveness of herbal medicines for weight loss: A systematic review and meta-analysis of randomized controlled trials.

AIM: To update the available evidence on the efficacy and safety of complementary medicines to assist in weight loss by conducting a systematic review and meta-analysis of herbal medicines for weight loss. METHODS: Four electronic databases (Medline, Embase, CINAHL and Web of Science) were searched from inception until August 2018. A total of 54 randomized placebo-controlled trials of healthy overweight or obese adults were identified. Meta-analyses were conducted for herbal medicines with ≥4 studies available. Weight differences of ≥2.5 kg were considered clinically significant. RESULTS: As a single agent, only Phaseolus vulgaris resulted in a statistically significant weight loss compared to placebo, although this was not considered clinically significant. No effect was seen for Camellia sinensis or Garcinia cambogia. Statistically, but not clinically, significant differences were observed for combination preparations containing C. sinensis, P. vulgaris or Ephedra sinica. Of the herbal medicines trialled in ≤3 randomized controlled trials, statistically and clinically significant weight loss compared to placebo was reported for Irvingia gabonensis, Cissus quadrangularis, and Sphaeranthus indicus combined with Garcinia mangostana, among others, but these findings should be interpreted cautiously because of the small number of studies, generally poor methodological quality, and poor reporting of the herbal medicine interventions. Most herbal medicines appeared safe for consumption over the short duration of the studies (commonly ≤12 weeks). Some warrant further investigation to determine effect size, dosage and long-term safety. CONCLUSION: There is currently insufficient evidence to recommend any of the herbal medicines for weight loss included in the present review.
