Inter- and transgenerational heritability of preconception chronic stress or alcohol exposure: Translational outcomes in brain and behavior.

Chronic stress and alcohol (ethanol) use are highly interrelated and can change an individual's behavior through molecular adaptations that do not change the DNA sequence, but instead change gene expression. A recent wealth of research has found that these nongenomic changes can be transmitted across generations, which could partially account for the "missing heritability" observed in genome-wide association studies of alcohol use disorder and other stress-related neuropsychiatric disorders. In this review, we summarize the molecular and behavioral outcomes of nongenomic inheritance of chronic stress and ethanol exposure and the germline mechanisms that could give rise to this heritability. In doing so, we outline the need for further research to: (1) Investigate individual germline mechanisms of paternal, maternal, and biparental nongenomic chronic stress- and ethanol-related inheritance; (2) Synthesize and dissect cross-generational chronic stress and ethanol exposure; (3) Determine cross-generational molecular outcomes of preconception ethanol exposure that contribute to alcohol-related disease risk, using cancer as an example. A detailed understanding of the cross-generational nongenomic effects of stress and/or ethanol will yield novel insight into the impact of ancestral perturbations on disease risk across generations and uncover actionable targets to improve human health.

Neuro-Ophthalmologic Monitoring in the Management of Increased Intracranial Pressure From Leaking Arachnoid Cysts.

BACKGROUND: Intracranial arachnoid cysts are common incidental imaging findings. They may rarely rupture, leading to the development of subdural hygromas and high intracranial pressure (ICP). Neurosurgical intervention has been advocated in the past, but recent evidence indicates that most cases resolve spontaneously. The role of neuro-ophthalmologic monitoring in identifying the few cases that have persisting vision-threatening papilledema that justifies intervention has not been emphasized. METHODS: Retrospective review of 4 cases of leaking arachnoid cysts drawn from the files of the University of Michigan Medical Center (Michigan Medicine) between 2007 and 2018. RESULTS: In 1 case, surgery was avoidable as papilledema resolved over time despite lingering imaging features of mass effect. In 3 cases, papilledema persisted with the threat of permanent vision loss, prompting neurosurgical intervention. In one of those cases, the fluid collection was thinly but extensively spread across both hemispheres without brain shift; yet, papilledema was pronounced. Emergent evacuation led to rapid resolution of papilledema and encephalopathy, but with residual optic nerve damage. CONCLUSIONS: Because constitutional symptoms and even imaging are not always reliable indicators of high ICP in leaking arachnoid cysts, neuro-ophthalmologic monitoring of papilledema is valuable in identifying the cases when neurosurgical intervention is necessary.

CSF flow jet: novel CT myelogram finding of CSF leak through dural tear in traumatic pseudomeningocele.

Determining the exact location of dural violation after traumatic pre-ganglionic (avulsion) injury of the brachial plexus with associated progressively enlarging pseudomeningocele is critical for treatment, but current imaging by MR and CT myelogram remains inadequate as there are often only indirect imaging features. We present a case of a 25-year-old man with history of motorcycle accident and left brachial plexus injury, who was found to have an extensive anterior epidural CSF collection, resulting in the contralateral neurologic deficit. Surgical treatment relies upon the identification of the site of the dural violation. On dynamic CT myelogram images, a thin hyperdense line of contrast was seen, representing "CSF flow jet" extravasating into the pseudomeningocele. Subsequent laminectomy and foraminotomy revealed a left avulsed nerve root and a dural tear at the site localized on the CT myelogram. To our knowledge, this is the first case of using dynamic CT myelography to visualize "CSF flow jet," revealing the exact location of dural violation resulting in the expanding pseudomeningocele, providing crucial information for perioperative planning.

Nonpharmacological Self-Management of Migraine Across Social Locations: An Equity-Oriented, Qualitative Analysis.

BACKGROUND: Migraine is a disabling neurological disorder and the sixth biggest cause of disability worldwide. The World Health Organization has declared migraine a major public health problem due to a paucity of knowledge about cause and effective treatment options. Both in incidence and severity, migraine disproportionately affects people occupying marginalized social locations (SL). Managed pharmacologically, migraine is treated with daily preventive and as-needed abortive medications. Both come with high literal and figurative costs: intolerable side effects, medication interactions, and prohibitive prices. Cost prohibitive, ineffective, and unsustainable pharmacological treatment options have contributed to high levels of interest in complementary approaches by people with migraine, but little is known about their motivations, patterns of use or access, or how these may vary by SL. METHOD: We conducted focus groups with 30 people with migraine to explore their desires and recommendations for migraine clinicians and researchers. We used qualitative content analysis to identify themes.Outcomes: We identified 4 themes: a more holistic, collaborative, long-term treatment approach; medication as a short-term solution; high personal and economic costs of medication; and desire for more information and access to natural approaches. Across SL, participants expressed keen interest in integrative approaches and wanted better access to complementary modalities. Participants in marginalized SL described reliance on traditional/folk remedies, including engagement with family and community healers, who they described as more affordable and culturally accessible. CONCLUSIONS: Holistic and integrative approaches were preferred over medication as long-term migraine management strategies. However, people in marginalized SL, while disproportionately disabled by migraine, did not feel as comfortable accessing integrative approaches through currently available channels. Engaging with these communities and using a critical lens to explore barriers to access can develop options to make complementary modalities more approachable, while also attending to systemic blind spots that may unintentionally alienate socially marginalized groups.

Measuring Contrast Sensitivity in Specific Areas of Vision - A Meaningful Way to Assess Quality of Life and Ability to Perform Daily Activities in Glaucoma.

Purpose: To investigate: 1) the impact of reduced contrast sensitivity (CS) in specific areas of vision on subjective assessment of vision-related quality of life (VRQoL) and objective performance-based measures in patients with primary open-angle, primary angle-closure, and pseudoexfoliation glaucoma; and 2) correlations between measurements of contrast sensitivity (CS) in specific areas of vision and visual field (VF) tests. Methods: The Spaeth/Richman Contrast Sensitivity Test (SPARCS) measured CS in the inferior, superior, and central areas, while the Pelli-Robson test measured central CS. Visual fields were tested in participants using standard-automated perimetry. The National Eye Institute Visual Function Questionnaire (NEI-VFQ-25) assessed VRQoL, and the Compressed Assessment of Ability Related to Vision (CAARV) assessed vision-related performance. Results: Three hundred and twenty-two eyes of 161 participants were included in our analysis. Significant correlations were found between CS and VF scores in the inferior, central, and superior areas (P < .0001 for all). Significant correlations were found between SPARCS scores in the inferior areas in both eyes and most CAARV scores (P < .05). Significant correlations were also found between SPARCS scores in the inferior and superior areas in the worse eye and most NEI-VFQ -25 scores (P < .05). Conclusion: Contrast sensitivity and VF scores significantly correlated in all tested areas. Reduced CS in the inferior areas of both eyes affected most performance-based measures. Measurement of CS areas using SPARCS is a meaningful way to assess VRQoL and ability to perform daily activities in participants with glaucoma.

A pooled analysis of three studies of nonpharmacological interventions for menopausal hot flashes.

OBJECTIVE: The aim of the study was to conduct a pooled analysis of three published trials of nonpharmacological interventions for menopausal hot flashes to compare the effectiveness of interventions. METHODS: Data from three randomized controlled trials of interventions for hot flashes (two acupuncture trials, one yoga trial) were pooled. All three studies recruited perimenopausal or postmenopausal women experiencing ≥4 hot flashes/d on average. The primary outcome for all three studies was frequency of hot flashes as measured by the Daily Diary of Hot Flashes. Study 1 participants were randomly assigned to 8 weeks of acupuncture treatments (active intervention), sham acupuncture (attention control), or usual care. Study 2 participants were randomly assigned to 10 weeks of yoga classes, health and wellness education classes (attention control), or waitlist control. Study 3 randomly assigned participants to 6 months of acupuncture or waitlist control. To standardize the time frame for these analyses, only the first 8 weeks of intervention from all three studies were used. RESULTS: The three active interventions and the two attention control groups had statistically similar trends in the percentage reduction of hot flashes over 8 weeks, ranging from 35% to 40%. These five groups did not differ significantly from each other, but all showed significantly greater reduction in hot flash frequency compared with the three usual care/waitlist groups. CONCLUSION: Acupuncture, yoga, and health and wellness education classes all demonstrated statistically similar effectiveness in reduction of hot flash frequency compared with controls.

A Critical Exploration of Migraine as a Health Disparity: the Imperative of an Equity-Oriented, Intersectional Approach.

PURPOSE OF REVIEW: Despite recognition of rising prevalence and significant burden, migraine remains underestimated, underdiagnosed, and undertreated. This is especially true among groups who have been historically, socially, and economically marginalized such as communities of color, women, people experiencing poverty, people with lower levels of education, and people who hold more than one of these marginalized identities. While there is growing public and professional interest in disparities in migraine prevalence, there is a paucity of research focusing on racial/ethnic and socioeconomic disparities, and the social and structural determinants of health and equity that perpetuate these disparities. From a health equity perspective, migraine research and treatment require an examination not only of biological and behavioral factors, but of these identities and underlying, intersecting social and structural determinants of health. RECENT FINDINGS: Significant disparities in migraine incidence, prevalence, migraine-related pain and disability, access to care, and quality of care persist among marginalized and underserved groups: African Americans, Hispanics, people experiencing poverty, un- or under-employment, the un- and under-insured, people who have been exposed to stressful and traumatic events across the lifespan, and people experiencing multiple, overlapping marginalized identities. These same groups are largely underrepresented in migraine research, despite bearing disproportionate burden. Current approaches to understanding health disparities in migraine largely assume an essentializing approach, i.e., documenting differences between single identity groups-e.g., race or income or education level-rather than considering the mechanisms of disparities: the social and structural determinants of health. While disparities in migraine are becoming more widely acknowledged, we assert that migraine is more aptly understood as a health equity issue, that is, a condition in which many of the health disparities are avoidable. It is important in research and clinical practice to consider perspectives that incorporate a cultural understanding of racial, ethnic, and socioeconomic identity within and across all levels of society. Incorporating perspectives of intersectionality provides a strong foundation for understanding the role of these complex combination of factors on migraine pain and treatment. We urge the adoption of intersectional and systems perspectives in research, clinical practice, and policy to examine (1) interplay of race, gender, and social location as key factors in understanding, diagnosing, and treating migraine, and (2) the complex configurations of social and structural determinants of health that interact to produce health inequities in migraine care. An intentional research and clinical focus on these factors stands to improve how migraine is identified, documented, and treated among marginalized populations.

A Qualitative, Systems Thinking Approach to Study Self-Management in Women With Migraine.

BACKGROUND: A dearth of effective and affordable treatment options has rendered nonpharmacological self-management a crucial part of living with migraine-a debilitating neurobiological condition without cure that disproportionately disables vulnerable women. OBJECTIVE: The aim of the study was to describe the development and use of a systems thinking, problem-structuring data collection approach that was applied to the study of migraine self-management with women in diverse social locations. METHODS: Two systems mapping activities were developed for use in focus groups: one to unpack a migraine episode (system support map) and the other (connection circle [CC]) to construct a mental model of self-management. Later in the process, a strengths-based problem-solving tool was developed to replace the CC. RESULTS: The CCs-often enlightening for affluent participants-left marginalized women feeling overwhelmed and defeated, as a solution to one challenge became the cause of another. Through constant comparison analysis, we recalibrated the approach using a theory, clinical experience, and participant feedback and replaced the CC with a strengths-based problem-solving activity highlighting relationships and trade-offs in a more agential, actionable way. DISCUSSION: Bringing a critical lens and strengths-based approaches to work with vulnerable populations can replace traditional deficit thinking in healthcare, developing options for leveraging resources and understanding complex health behaviors without losing sight of systemic, distributional justice issues. These systems thinking tools can provide a way to extrapolate the complexities of actual self-management behaviors and challenges faced by vulnerable women with migraine versus what they may be instructed to do by a medical model that does not always account for the social and structural determinants of equity and health.

Nonpharmacologic Treatments for Attention-Deficit/Hyperactivity Disorder: A Systematic Review.

CONTEXT: Nonpharmacologic treatments for attention-deficit/hyperactivity disorder (ADHD) encompass a range of care approaches from structured behavioral interventions to complementary medicines. OBJECTIVES: To assess the comparative effectiveness of nonpharmacologic treatments for ADHD among individuals 17 years of age and younger. DATA SOURCES: PubMed, Embase, PsycINFO, and Cochrane Database of Systematic Reviews for relevant English-language studies published from January 1, 2009 through November 7, 2016. STUDY SELECTION: We included studies that compared any ADHD nonpharmacologic treatment strategy with placebo, pharmacologic, or another nonpharmacologic treatment. DATA EXTRACTION: Study design, patient characteristics, intervention approaches, follow-up times, and outcomes were abstracted. For comparisons with at least 3 similar studies, random-effects meta-analysis was used to generate pooled estimates. RESULTS: We identified 54 studies of nonpharmacologic treatments, including neurofeedback, cognitive training, cognitive behavioral therapy, child or parent training, dietary omega fatty acid supplementation, and herbal and/or dietary approaches. No new guidance was identified regarding the comparative effectiveness of nonpharmacologic treatments. Pooled results for omega fatty acids found no significant effects for parent rating of ADHD total symptoms (n = 411; standardized mean difference -0.32; 95% confidence interval -0.80 to 0.15; I2 = 52.4%; P = .10) or teacher-rated total ADHD symptoms (n = 287; standardized mean difference -0.08; 95% confidence interval -0.47 to 0.32; I2 = 0.0%; P = .56). LIMITATIONS: Studies often did not reflect the primary care setting and had short follow-up periods, small sample sizes, variations in outcomes, and inconsistent reporting of comparative statistical analyses. CONCLUSIONS: Despite wide use, there are significant gaps in knowledge regarding the effectiveness of ADHD nonpharmacologic treatments.

Acupuncture for Chronic Pain in the Vermont Medicaid Population: A Prospective, Pragmatic Intervention Trial.

INTRODUCTION: In response to the opioid crisis, the 2016 Vermont legislature commissioned a study to assess acupuncture for patients with chronic pain in the Vermont Medicaid population. OBJECTIVE: To assess the feasibility, acceptability, and effectiveness of acupuncture provided by licensed acupuncturists for Vermont Medicaid patients with chronic pain. METHODS: A total of 156 Medicaid patients with chronic pain were offered up to 12 acupuncture treatments within a 60-day period at the offices of 28 Vermont licensed acupuncturists. PROMIS® questionnaires were administered prior to and at the end of the treatment period to assess changes in pain intensity, pain interference, physical function, fatigue, anxiety, depression, sleep disturbance, and social isolation. Questionnaires also captured patients' overall impressions of treatments as well as self-reported changes in medication use and work function. RESULTS: One hundred eleven women (71%) and 45 men (29%) with a wide range of pain complaints received a mean of 8.2 treatments during the intervention period. Measurements captured prior to and at the end of the treatment period showed significant improvements in group mean pain intensity, pain interference, physical function, fatigue, anxiety, depression, sleep disturbance, and social isolation as assessed by Patient-Reported Outcomes Measurement Information System (PROMIS) measures (paired t tests, P < .01). Fifty-seven percent of patients using analgesic (nonopioid) medication reported reductions in use. Thirty-two percent of patients using opioid medication reported reductions in use of opioid medication following the intervention. Seventy-four percent of employed patients reported improved capacity to work. Ninety-six percent of patients said that they would recommend acupuncture to others with chronic pain, and 91% reported qualitative improvements, including physical (31%), functional/behavioral (29%), and psycho-emotional (24%) improvements. CONCLUSIONS: Our findings demonstrate that acupuncture treatment for chronic pain is feasible and well received by patients in the Vermont Medicaid population. Receiving care from Licensed Acupuncturists was associated with significant improvements in physical, functional, psycho-emotional, and occupational outcomes compared with before receiving acupuncture treatments.

Management of Menopause Symptoms with Acupuncture: An Umbrella Systematic Review and Meta-Analysis.

OBJECTIVES: Vasomotor symptoms (VMSs) are the most common symptoms reported during menopause. Although hormone therapy is effective for reducing VMSs, its use is restricted in some women. Many women with VMSs thus seek nonhormonal, nonpharmacologic treatment options such as acupuncture. DESIGN: An umbrella systematic review (SR) was conducted, supplemented by a search of published randomized controlled trials (RCTs), that assessed the effectiveness of acupuncture for VMSs, health-related quality of life (HRQOL), and adverse effects of treatment in perimenopausal or postmenopausal women. Meta-analyses were conducted using a random-effects model when data were sufficient. RESULTS: Three SRs and four new RCTs were identified that met eligibility criteria. Meta-analyses of this study revealed statistically significant standardized mean differences (SMDs) associated with acupuncture compared with no acupuncture at reducing VMS frequency (SMD -0.66, 95% confidence interval [CI] -1.06 to -0.26, I2 = 61.7%, 5 trials) and VMS severity (SMD -0.49, 95% CI -0.85 to -0.13, I2 = 18.1%, 4 trials) and improving HRQOL outcomes (SMD -0.93, 95% CI -1.20 to -0.67, I2 = 0.0%, 3 trials). SMDs were smaller or not statistically significant when acupuncture was compared with sham acupuncture. CONCLUSIONS: Evidence from RCTs supports the use of acupuncture as an adjunctive or stand-alone treatment for reducing VMSs and improving HRQOL outcomes, with the caveat that observed clinical benefit associated with acupuncture may be due, in part, or in whole to nonspecific effects. The safety of acupuncture in the treatment of VMSs has not been rigorously examined, but there is no clear signal for a significant potential for harm.

Orbital infantile hemangioma and rhabdomyosarcoma in children: differentiation using diffusion-weighted magnetic resonance imaging.

PURPOSE: To evaluate differences in magnetic resonance imaging (MRI) appearance between infantile hemangiomas and rhabdomyosarcomas of the orbit in pediatric patients using diffusion-weighted imaging. METHODS: A multicenter retrospective review of MRIs of pediatric patients with infantile hemangiomas and rhabdomyosarcomas of the orbit was performed. MRI examinations from a total of 21 patients with infantile hemangiomas and 12 patients with rhabdomyosarcomas of the orbit were independently reviewed by two subspecialty board-certified neuroradiologists masked to the diagnosis. A freehand region of interest was placed in the mass to obtain the mean apparent diffusion coefficient (ADC) value of the mass as well as within the medulla to obtain a ratio of the ADC mass to the medulla. A t test was used to compare mean ADC and ADC ratios between the two groups. Receiver operating characteristic analysis was performed to determine ADC value and ADC ratio thresholds for differentiation of infantile hemangioma and rhabdomyosarcoma. RESULTS: There was a statistically significant difference in the mean ADC value of infantile hemangiomas compared to rhabdomyosarcomas (1527 × 10-6 mm2/s vs 782 × 10-6 mm2/s; P = 0.0001) and the ADC ratio of the lesion to the medulla (1.77 vs 0.92; P = 0.0001). An ADC threshold of <1159 × 10-6 mm2/sec and an ADC ratio of <1.38 differentiated rhabdomyosarcoma from infantile hemangioma (sensitivity 100% and 100%; specificity 100% and 100%) with area under the curve of 1.0 and 1.0, respectively. CONCLUSIONS: In conjunction with conventional MRI sequences, ADC values obtained from diffusion-weighted MRI are useful to differentiate orbital infantile hemangiomas from rhabdomyosarcomas in pediatric patients.

Species-specific responses to climate change and community composition determine future calcification rates of Florida Keys reefs.

Anthropogenic climate change compromises reef growth as a result of increasing temperatures and ocean acidification. Scleractinian corals vary in their sensitivity to these variables, suggesting species composition will influence how reef communities respond to future climate change. Because data are lacking for many species, most studies that model future reef growth rely on uniform scleractinian calcification sensitivities to temperature and ocean acidification. To address this knowledge gap, calcification of twelve common and understudied Caribbean coral species was measured for two months under crossed temperatures (27, 30.3 °C) and CO2 partial pressures (pCO2 ) (400, 900, 1300 µatm). Mixed-effects models of calcification for each species were then used to project community-level scleractinian calcification using Florida Keys reef composition data and IPCC AR5 ensemble climate model data. Three of the four most abundant species, Orbicella faveolata, Montastraea cavernosa, and Porites astreoides, had negative calcification responses to both elevated temperature and pCO2 . In the business-as-usual CO2 emissions scenario, reefs with high abundances of these species had projected end-of-century declines in scleractinian calcification of >50% relative to present-day rates. Siderastrea siderea, the other most common species, was insensitive to both temperature and pCO2 within the levels tested here. Reefs dominated by this species had the most stable end-of-century growth. Under more optimistic scenarios of reduced CO2 emissions, calcification rates throughout the Florida Keys declined <20% by 2100. Under the most extreme emissions scenario, projected declines were highly variable among reefs, ranging 10-100%. Without considering bleaching, reef growth will likely decline on most reefs, especially where resistant species like S. siderea are not already dominant. This study demonstrates how species composition influences reef community responses to climate change and how reduced CO2 emissions can limit future declines in reef calcification.

Trajectories of response to acupuncture for menopausal vasomotor symptoms: the Acupuncture in Menopause study.

OBJECTIVE: To examine the trajectories of responses to acupuncture treatment for menopausal vasomotor symptoms (VMS) and the characteristics of women in each trajectory. METHODS: Two hundred nine perimenopausal and postmenopausal women aged 45 to 60 years experiencing at least four VMS per day were recruited and randomized to receive up to 20 acupuncture treatments within 6 months or to a waitlist control group. The primary outcome was percent change from baseline in the mean daily VMS frequency. Finite mixture modeling was used to identify patterns of percent change in weekly VMS frequencies over the first 8 weeks. The Freeman-Holton test and analysis of variance were used to compare characteristics of women in different trajectories. RESULTS: Analyses revealed four distinct trajectories of change in VMS frequency by week 8 in the acupuncture group. A small group of women (11.6%, n = 19) had an 85% reduction in VMS. The largest group (47%, n = 79) reported a 47% reduction in VMS frequency, 37.3% (n = 65) of the sample showed only a 9.6% reduction in VMS frequency, and a very small group (4.1%, n = 7) had a 100% increase in VMS. Among women in the waitlist control group, 79.5% reported a 10% decrease in VMS frequency at week 8. Baseline number of VMS, number of acupuncture treatments in the first 8 weeks, and traditional Chinese medicine diagnosis were significantly related to trajectory group membership in the acupuncture group. CONCLUSIONS: Approximately half of the treated sample reported a decline in VMS frequency, but identifying clear predictors of clinical response to acupuncture treatment of menopausal VMS remains challenging.

Role of Acupuncture in the Treatment or Prevention of Migraine, Tension-Type Headache, or Chronic Headache Disorders.

OBJECTIVE: To summarize the current evidence that evaluates the effectiveness of acupuncture for the treatment or prevention of migraine, tension-type headache, and chronic headache disorders. METHODS: Findings from selected systematic reviews and meta-analyses are summarized. RESULTS: Recently published systematic reviews and meta-analyses demonstrate that acupuncture is associated with improved clinical outcomes compared to routine care only, medical management, and sham acupuncture 2 months after randomization. The evidence in support of acupuncture's comparative effectiveness at longer follow-up periods is mixed. Cost effectiveness analyses conducted in the United Kingdom and Germany suggest that acupuncture is a cost-effective treatment option in those countries. There are few or no cost-effectiveness studies of acupuncture in the United States. DISCUSSION: This brief review of the current, published evidence does not include a discussion of potential risks or adverse events associated with acupuncture. There is also the question of the extent to which placebo effects might contribute to acupuncture's clinical effectiveness. From a purely comparative effectiveness perspective, however, the evidence from clinical trials and meta-analyses makes a compelling case in support of a potentially important role for acupuncture as part of a treatment plan for patients with migraine, tension-type headache, and several different types of chronic headache disorders.

An evidence map of yoga for low back pain.

OBJECTIVE: Yoga is being increasingly studied as a treatment strategy for a variety of different clinical conditions, including low back pain (LBP). We set out to conduct an evidence map of yoga for the treatment, prevention and recurrence of acute or chronic low back pain (cLBP). METHODS: We searched Medline, Cochrane Database of Systematic Reviews, EMBASE, Allied and Complementary Medicine Database and ClinicalTrials.gov for randomized controlled trials (RCT), systematic reviews or planned studies on the treatment or prevention of acute back pain or cLBP. Two independent reviewers screened papers for inclusion, extracted data and assessed the quality of included studies. RESULTS: Three eligible systematic reviews were identified that included 10 RCTs (n=956) that evaluated yoga for non-specific cLBP. We did not identify additional RCTs beyond those included in the systematic reviews. Our search of ClinicalTrials.gov identified one small (n=10) unpublished trial and one large (n=320) planned clinical trial. The most recent good quality systematic review indicated significant effects for short- and long-term pain reduction (n=6 trials; standardized mean difference [SMD] -0.48; 95% CI, -0.65 to -0.31; I(2)=0% and n=5; SMD -0.33; 95% CI, -0.59 to -0.07; I(2)=48%, respectively). Long-term effects for back specific disability were also identified (n=5; SMD -0.35; 95% CI, -0.55 to -0.15; I(2)=20%). No studies were identified evaluating yoga for prevention or treatment of acute LBP. CONCLUSION: Evidence suggests benefit of yoga in midlife adults with non-specific cLBP for short- and long-term pain and back-specific disability, but the effects of yoga for health-related quality of life, well- being and acute LBP are uncertain. Without additional studies, further systematic reviews are unlikely to be informative.

Nonpharmacologic, nonherbal management of menopause-associated vasomotor symptoms: an umbrella systematic review (protocol).

BACKGROUND: Vasomotor symptoms such as hot flashes and night sweats are a common concern of perimenopausal and postmenopausal women and are associated with a decreased quality of life. These symptoms can be effectively managed with hormone therapy, but safety concerns limit its use. Thus, understanding the effectiveness of nonpharmacologic therapies such as acupuncture or yoga is critical to managing these common symptoms in older women. Our review seeks to address the following question: In women with menopause-associated vasomotor symptoms, what are the effects on health-related quality of life, vasomotor symptoms, and adverse events of the following nonpharmacologic, nonherbal interventions as compared with any inactive control or active comparator: (a) acupuncture, (b) yoga, tai chi, and qigong, (c) structured exercise, and (d) meditation, mindfulness-based practices, and relaxation? METHODS: We describe a protocol for an umbrella review approach, supplemented by evaluating randomized controlled trials (RCTs) published after the most recent good-quality systematic review for each of the eligible interventions. Specific interventions were chosen based on current literature and with input from a technical expert panel and organizational stakeholders. We will conduct a thorough literature search and perform a quality assessment of potentially included systematic reviews and RCTs. DISCUSSION: Our umbrella review, supplemented by an additional search for eligible RCTs, aims to synthesize existing evidence on the use of nonpharmacologic, nonherbal interventions to manage bothersome vasomotor symptoms in perimenopausal and postmenopausal women.
