Prevention and control of non-communicable diseases in antenatal, intrapartum, and postnatal care: a systematic scoping review of clinical practice guidelines since 2011.

BACKGROUND: Non-communicable diseases (NCDs) are a leading cause of maternal mortality and morbidity worldwide. The World Health Organization is developing new recommendations focusing on the management of NCDs for pregnant, intrapartum, and postnatal women. Thus, to support the development of new guidelines and recommendations, we aimed to determine the availability, focus, and scope of recommendations of current guidelines for the management of NCDs during pregnancy, intrapartum, and postnatal period. METHODS: PubMed, Global Index Medicus, TRIP, and Guideline International Network databases were searched on 31 May 2021, to identify any NCD-related guidelines published between 2011 and 2021 with no language or country restrictions. Websites of 165 professional organizations were also searched. Characteristics of included guidelines were analyzed, and recommendations were extracted from guidelines of five high-priority NCD conditions (diabetes, chronic hypertension, respiratory conditions, hemoglobinopathies and sickle cell disease, and mental and substance use disorders). RESULTS: From 6026 citations and 165 websites, 405 guidelines were included of which 132 (33%) were pregnancy-specific and 285 (88%) were developed in high-income countries. Among pregnancy-specific guidelines, the most common conditions for which recommendations were provided were gestational diabetes, circulatory diseases, thyroid disorders, and hypertensive disorders of pregnancy. For the five high-priority conditions, 47 guidelines were identified which provided 1834 recommendations, largely focused on antenatal care interventions (62%) such as early detection, screening tools, pharmacological treatment, and lifestyle education. Postnatal recommendations largely covered postnatal clinical assessments, lifestyle education, and breastfeeding. Health system recommendations largely covered multidisciplinary care teams and strengthening referral pathways. CONCLUSIONS: This study provides a robust assessment of currently available guidelines and mapping of recommendations on NCD management within maternal health services, which will inform the scope of the World Health Organization's future guideline development activities. This study identified a need to develop guidelines that consider NCDs holistically, with an integrated approach to antenatal, intrapartum, and postnatal care, and that are relevant for resource-limited contexts. Any such guidelines should consider what interventions are most essential to improving outcomes for women with NCDs and their newborns, and how variations in quality of NCD-related care can be addressed.

Mindfulness-based psychological interventions for improving mental well-being in medical students and junior doctors.

BACKGROUND: Mindfulness interventions are increasingly popular as an approach to improve mental well-being. To date, no Cochrane Review examines the effectiveness of mindfulness in medical students and junior doctors. Thus, questions remain regarding the efficacy of mindfulness interventions as a preventative mechanism in this population, which is at high risk for poor mental health.  OBJECTIVES: To assess the effects of psychological interventions with a primary focus on mindfulness on the mental well-being and academic performance of medical students and junior doctors. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and five other databases (to October 2021) and conducted grey literature searches.  SELECTION CRITERIA: We included randomised controlled trials of mindfulness that involved medical students of any year level and junior doctors in postgraduate years one, two or three. We included any psychological intervention with a primary focus on teaching the fundamentals of mindfulness as a preventative intervention. Our primary outcomes were anxiety and depression, and our secondary outcomes included stress, burnout, academic performance, suicidal ideation and quality of life.  DATA COLLECTION AND ANALYSIS: We used standard methods as recommended by Cochrane, including Cochrane's risk of bias 2 tool (RoB2).  MAIN RESULTS: We included 10 studies involving 731 participants in quantitative analysis.  Compared with waiting-list control or no intervention, mindfulness interventions did not result in a substantial difference immediately post-intervention for anxiety (standardised mean difference (SMD) 0.09, 95% CI -0.33 to 0.52; P = 0.67, I2 = 57%; 4 studies, 255 participants; very low-certainty evidence). Converting the SMD back to the Depression, Anxiety and Stress Scale 21-item self-report questionnaire (DASS-21) showed an estimated effect size which is unlikely to be clinically important. Similarly, there was no substantial difference immediately post-intervention for depression (SMD 0.06, 95% CI -0.19 to 0.31; P = 0.62, I2 = 0%; 4 studies, 250 participants; low-certainty evidence). Converting the SMD back to DASS-21 showed an estimated effect size which is unlikely to be clinically important. No studies reported longer-term assessment of the impact of mindfulness interventions on these outcomes.  For the secondary outcomes, the meta-analysis showed a small, substantial difference immediately post-intervention for stress, favouring the mindfulness intervention (SMD -0.36, 95% CI -0.60 to -0.13; P < 0.05, I2 = 33%; 8 studies, 474 participants; low-certainty evidence); however, this difference is unlikely to be clinically important. The meta-analysis found no substantial difference immediately post-intervention for burnout (SMD -0.42, 95% CI -0.84 to 0.00; P = 0.05, I² = 0%; 3 studies, 91 participants; very low-certainty evidence). The meta-analysis found a small, substantial difference immediately post-intervention for academic performance (SMD -0.60, 95% CI -1.05 to -0.14; P < 0.05, I² = 0%; 2 studies, 79 participants; very low-certainty evidence); however, this difference is unlikely to be clinically important. Lastly, there was no substantial difference immediately post-intervention for quality of life (mean difference (MD) 0.02, 95% CI -0.28 to 0.32; 1 study, 167 participants; low-certainty evidence). There were no data available for three pre-specified outcomes of this review: deliberate self-harm, suicidal ideation and suicidal behaviour. We assessed the certainty of evidence to range from low to very low across all outcomes. Across most outcomes, we most frequently judged the risk of bias as having 'some concerns'. There were no studies with a low risk of bias across all domains.  AUTHORS' CONCLUSIONS: The effectiveness of mindfulness in our target population remains unconfirmed. There have been relatively few studies of mindfulness interventions for junior doctors and medical students. The available studies are small, and we have some concerns about their risk of bias. Thus, there is not much evidence on which to draw conclusions on effects of mindfulness interventions in this population. There was no evidence to determine the effects of mindfulness in the long term.

Non-steroidal anti-inflammatory drugs (NSAIDs) for treating lateral elbow pain in adults.

BACKGROUND: Lateral elbow pain, or tennis elbow, is a common condition that causes pain in the elbow and forearm. Although self-limiting, it can be associated with significant disability and often results in work absence. It is often treated with topical and oral non-steroidal anti-inflammatory drugs (NSAIDs). This is an update of a review first published in 2002 (search date October 11, 2012). OBJECTIVES: To assess the benefits and harms of topical and oral NSAIDs for treating people with lateral elbow pain. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials, MEDLINE, CINAHL, EMBASE and SciSearch up to October 11, 2012. No language restriction was applied. SELECTION CRITERIA: Studies were included if they were randomised or quasi-randomised controlled trials (RCTs or CCTs) that compared topical or oral NSAIDs with placebo or another intervention, or compared two NSAIDs in adults with lateral elbow pain. Outcomes of interest were pain, function, quality of life, pain-free grip strength, overall treatment success, work loss and adverse effects. DATA COLLECTION AND ANALYSIS: Two review authors independently selected the studies for inclusion, extracted the data, and performed a risk of bias assessment. MAIN RESULTS: Fifteen trials, involving 759 participants and reporting 17 comparisons, were included in the review. Four new trials identified from the updated search were included, along with 11 of 14 trials included in the original review (three trials included in the previous review were found not to meet inclusion criteria). Of eight trials that studied topical NSAIDs (301 participants), five compared topical NSAIDs with placebo, one compared manipulative therapy and topical NSAIDs with manipulative therapy alone, one compared leech therapy with topical NSAIDs and one compared two different topical NSAIDs. Of seven trials that investigated oral NSAIDs (437 participants), two compared oral NSAIDs with placebo, one compared oral NSAIDs and bandaging with bandaging alone, three compared oral NSAIDs with glucocorticoid injection, one compared oral NSAIDs with a vasodilator and two compared two different oral NSAIDs. No trials directly compared topical NSAIDs with oral NSAIDs. Few trials used intention-to-treat analysis, and the sample size of most was small. The median follow-up was 2 weeks (range 1 week to 1 year).Low-quality evidence was obtained from three trials (153 participants) suggesting that topical NSAIDs were significantly more effective than placebo with respect to pain in the short term (mean difference -1.64, 95% confidence interval (CI) -2.42 to -0.86) and number needed to treat to benefit (7 (95% CI 3 to 21) on a 0 to 10 scale). Low-quality evidence was obtained from one trial (85 participants) indicating that significantly more participants report fair, good or excellent effectiveness with topical NSAIDs versus placebo at 28 days (14 days of therapy) (risk ratio (RR) 1.49, 95% CI 1.04 to 2.14). No participants withdrew as the result of adverse events, but some studies reported mild adverse effects such as rash in 2.5% of those exposed to topical NSAIDs compared with 1.3% of those exposed to placebo.Low-quality and conflicting evidence regarding the benefits of oral NSAIDs obtained from two trials could not be pooled. One trial found significantly greater improvement in pain compared with placebo, and the other trial found no between-group differences; neither trial found differences in function. One trial reported a withdrawal due to adverse effects for a participant in the NSAIDs group. Use of oral NSAIDs was associated with increased risk of gastrointestinal side effects compared with placebo in one trial in the review. Another trial reported discontinuation of treatment due to gastrointestinal side effects in four participants taking NSAIDs, and another participant developed an allergic reaction in response to oral NSAIDs.Very scant and conflicting evidence regarding the comparative effects of oral NSAIDs and glucocorticoid injection was obtained. One trial reported a significant improvement in pain with glucocorticoid injection, and another found no between-group differences; treatment success was similar between groups (RR of fair, good or excellent effectiveness 0.74; 95% CI 0.43 to 1.26). Transient pain may occur following injection. AUTHORS' CONCLUSIONS: There remains limited evidence from which to draw firm conclusions about the benefits or harms of topical or oral NSAIDs in treating lateral elbow pain. Although data from five placebo-controlled trials suggest that topical NSAIDs may be beneficial in improving pain (for up to 4 weeks), non-normal distribution of data and other methodological issues precluded firm conclusions. Some people may expect a mild transient skin rash. Evidence about the benefits of oral NSAIDs has been conflicting, although oral NSAID use may result in gastrointestinal adverse effects in some people. No direct comparisons between oral and topical NSAIDs were available. Some trials demonstrated greater benefit from glucocorticoid injection than from NSAIDs in the short term, but this was not apparent in all studies and was not apparent by 6 months in the only study that included longer-term outcomes.
