Plain language summary
Endometriosis is a gynaecological condition with symptoms of pelvic pain, fatigue, and stress. Decreased quality of life, impaired fertility and hinderances to carry out day to day tasks are all associated with endometriosis. Treatment options involve medications and surgery; however, both are associated with poorer outcomes than the initial disease itself. Self-management strategies that the individual can perform themselves, such as lifestyle changes, meditation, and rest have all been used to improve the quality of life of individuals with endometriosis, however their effectiveness has not been determined. This systematic review and meta-analysis aimed to determine the effectiveness of self-management strategies for the management of endometriosis. The study showed that many self-management strategies were no more effective than placebo or hormonal therapies for the management of endometriosis. It was concluded that many self-management strategies were no more effective than hormonal treatment at reducing endometriosis symptoms and the studies that did show a benefit were insufficient to base recommendations on due to poor design. This study could be used by healthcare professionals to understand that currently the research on self-management strategies of endometriosis is poor and whilst some may be of benefit to individuals who cannot or do not want to take hormone therapy, more research is warranted.

Summary Review:
Introduction
Endometriosis is an inflammatory condition where endometrial-like tissue is found outside of the uterus. Diagnosis of endometriosis is made in around 6-10% of females of reproductive age. Endometriosis can adversely affect fertility, psychological well being and quality of life (QoL). Conventional interventions can have side effects and limited effectiveness. The aim of this systematic review (SR) was to evaluate the efficacy of self-management interventions for pain-related symptoms and QoL.
Methods
Fifteen experimental studies were included in this SR. Ten evaluated dietary supplements, three evaluated dietary modifications, one evaluated over-the-counter (OTC) medication, and one evaluated exercise. Outcome measures were self-reported for dysmenorrhoea, dyspareunia, overall pain, non-menstrual pelvic pain, use of medications and QoL.
Results
- Most dietary supplements were no more effective than placebo or frequently recommended medical interventions, at reducing pain-related outcomes.
- Melatonin (one RCT n=30) performed better than placebo for managing dysmenorrhoea and overall pain but not for non-menstrual pelvic pain. PEA-transploydatin (one RCT n=20) performed better than placebo for dysmenorrhoea and non-menstrual pelvic pain but not better than medical intervention.
- Resveratrol (one RCT n=22 & one intervention study n=12) plus the oral contraceptive pill (OCP) was more effective than the OCP alone for managing dysmenorrhoea.
- In one observational study, 75% of participants (n=295) reported a reduction in ‘high’ intensity pain scores following a 12-month gluten-free diet (p- value =<0.005). Similarly, a full dietary modification (one non randomised controlled trial , n=30) found less participants reporting pain at ‘high intensity’ (18%) compared to linseed and calcium oil supplements (41%) and placebo (62%).
- A metal trace element supplement was more effective than placebo for managing overall pain (one RCT p- value<0.001).
- Naproxen (one cross over trial, n=11) performed better than placebo at managing dysmenorrhoea (83% vs 41%, p- value 0.008).
- Hatha yoga (one RCT n=12) was found to be effective at reducing overall pain and improving QoL compared to no yoga (p-value <0.05).
Conclusion
Due to limited, low-quality evidence, high risk of bias and high levels of heterogeneity between studies, it was not possible to generalise the findings of the studies included in this systematic review. Further research of high-quality is needed in order to make self-management recommendations for females with endometriosis.
Notes: The authors reported no conflicts of interest.
Clinical practice applications:
Evidence-based self-management interventions are considered critical for the management of endometriosis. However, the quality of evidence in this SR was considered of poor quality. Further high-quality research is needed in order to be able to make recommendations. Strategies that showed potential benefits included:
- Dietary modifications and a gluten-free diet may be effective for reducing the intensity of pain associated with endometriosis.
- Hatha yoga may be effective at reducing overall pain and supporting psychological wellbeing and QoL.
Considerations for future research:
High quality studies are needed as well as a ‘gold standard’ definition for self-management criteria. Understanding potential barriers to self-management interventions may also be beneficial.
Abstract
Self-management is critical for the care of endometriosis. Females with endometriosis frequently use self-management strategies to manage associated symptoms; however, the efficacy of such strategies is unknown. The aim of this review was to systematically appraise the evidence concerning efficacy of self-management strategies for endometriosis symptoms. Electronic databases, including Medline, Embase, Emcare, Web of Science Core Collection, Scopus, and the Cochrane Central Register of Controlled Trials, were searched from inception to March 2021. We included peer-reviewed experimental studies published in English evaluating the efficacy of self-management strategies in human females laparoscopically diagnosed with endometriosis. Studies underwent screening, data extraction, and risk of bias appraisal (randomised studies: Risk of Bias 2 tool; non-randomised studies: Risk Of Bias In Non-randomized Studies - of Interventions tool). Of the fifteen studies included, 10 evaluated dietary supplements, three evaluated dietary modifications, one evaluated over-the-counter medication, and one evaluated exercise. Most studies had a high-critical risk of bias. Many self-management strategies were not more effective at reducing endometriosis symptoms compared to placebo or hormonal therapies. Where studies suggest efficacy for self-management strategies, no recommendations can be made due to the poor quality and heterogeneity of evidence. High-quality empirical evidence is required to investigate the efficacy of self-management strategies for females with endometriosis.

Plain language summary
Migraine and headaches can be a seriously debilitating disorder for those who suffer from them. The exact cause is still unknown; however, it is thought that inflammation in the body and the blood vessels which serve the brain may be part of the problem. Alpha-lipoic acid (ALA) is a nutrient that is found in foods such as broccoli and organ meats and it is also produced within the body. It has been shown to have anti-inflammatory effects and therefore may be of benefit to those individuals who have headaches and migraines. This 12-week randomised control study of 92 individuals with migraine aimed to determine the effects of ALA supplementation on measures of inflammation in the blood vessels and symptoms. The results showed that oxygen passage to the brain was improved, which resulted in an improvement to migraine severity and frequency. It was concluded that ALA supplementation could be considered a possible migraine treatment in conjunction with regular pain medications for migraine symptoms. This study could be used by healthcare professionals to recommend the consumption of ALA as part of migraine management.
Abstract
The current study was performed to evaluate the effects of alpha-lipoic acid (ALA) supplementation on lactate, nitric oxide (NO), vascular cell adhesion molecule-1 (VCAM-1) levels, and clinical symptoms in women with episodic migraines. Considering the inclusion and exclusion criteria, ninety-two women with episodic migraines participated in this randomized, double-blind, placebo-controlled, parallel-design trial. The participants were randomly assigned to receive either 300 mg/day ALA or placebo, twice per day for 12 weeks. The primary outcomes included headache severity, headache frequency per month, and duration of attacks and the secondary outcomes included lactate (a marker of mitochondrial function), NO, and VCAM-1 serum levels were measured at baseline and the end of the intervention. At the end of the study, there was a significant decrease in lactate serum levels (- 6.45 ± 0.82 mg/dl vs - 2.27 ± 1.17 mg/dl; P = 0.039) and VCAM-1 (- 2.02 ± 0.30 ng/ml vs - 1.21 ± 0.36 ng/ml; P = 0.025) in the ALA as compared to the placebo group. In addition, the severity (P < 0.001), frequency (P = 0.001), headache impact test (HIT-6) (P < 0.001), headache dairy results (HDR) (P = 0.003), and migraine headache index score (MHIS) (P < 0.001) had significantly decreased in the intervention as compared to the control group. No significant changes were observed for NO levels and duration of migraine pains. ALA supplementation can be considered a potential adjunct treatment in patients with migraine due to its improving mitochondrial and endothelial functions and clinical symptoms.
