Dry Needling for the Treatment of Tension-Type, Cervicogenic, or Migraine Headaches: A Systematic Review and Meta-Analysis.

OBJECTIVE: Dry needling is a treatment technique used by clinicians to relieve symptoms in patients with tension-type headache (TTH), cervicogenic headache (CGH), or migraine. This systematic review's main objective was to assess the effectiveness of dry needling on headache pain intensity and related disability in patients with TTH, CGH, or migraine. METHODS: Medline/PubMed, Scopus, Embase, PEDro, Web of Science, Ovid, Allied and Complementary Medicine Database/EBSCO, Cochrane Central Register of Controlled Clinical Trials, Google Scholar, and trial registries were searched until April 1, 2020, along with reference lists of eligible studies and related reviews. Randomized clinical trials or observational studies that compared the effectiveness of dry needling with any other interventions were eligible for inclusion. Three reviewers independently selected studies, extracted data, and assessed risk of bias. Random-effects meta-analyses were performed to produce pooled-effect estimates (Morris dppc2) and their respective CIs. RESULTS: Of 2715 identified studies, 11 randomized clinical trials were eligible for qualitative synthesis and 9 for meta-analysis. Only 4 trials were of high quality. Very low-quality evidence suggested that dry needling is not statistically better than other interventions for improving headache pain intensity in the short term in patients with TTH (SMD -1.27, 95% CI = -3.56 to 1.03, n = 230), CGH (SMD -0.41, 95% CI = -4.69 to 3.87, n = 104), or mixed headache (TTH and migraine; SMD 0.03; 95% CI = -0.42 to 0.48, n = 90). Dry needling provided significantly greater improvement in related disability in the short term in patients with TTH (SMD -2.28, 95% CI = -2.66 to -1.91, n = 160) and CGH (SMD -0.72, 95% CI = -1.09 to -0.34, n = 144). The synthesis of results showed that dry needling could significantly improve headache frequency, health-related quality of life, trigger point tenderness, and cervical range of motion in TTH and CGH. CONCLUSIONS: Dry needling produces similar effects to other interventions for short-term headache pain relief, whereas dry needling seems to be better than other therapies for improvement in related disability in the short term. IMPACT: Although further high-methodological quality studies are warranted to provide a more robust conclusion, our systematic review suggested that for every 1 or 2 patients with TTH treated by dry needling, 1 patient will likely show decreased headache intensity (number needed to treat [NNT] = 2; large effect) and improved related disability (NNT = 1; very large effect). In CGH, for every 3 or 4 patients treated by dry needling, 1 patient will likely exhibit decreased headache intensity (NNT = 4; small effect) and improved related disability (NNT = 3; medium effect).

The effect of Capsaicinoids or Capsinoids in red pepper on thermogenesis in healthy adults: A systematic review and meta-analysis.

The outcomes of the earlier trials are controversial concerning the effect of Capsaicinoids/Capsinoids on thermogenesis. We carried out this systematic review and meta-analysis to examine the effect of Capsaicinoids/Capsinoids on thermogenesis indices including resting metabolic rate (RMR) and respiratory quotient (RQ) in healthy adults. An electronic literature search was conducted between 1990 and 2019, using the following databases: PubMed, Web of Sciences, Scopus, Cochrane Central Register of Controlled Trials, and EMBASE. Placebo-controlled clinical trials were considered as eligible papers. Effect sizes were pooled using weighted mean difference (WMD), with a random-effects model. Of the 4,092 articles, 13 studies were included in the meta-analysis. Pooled effect sizes revealed that compared with placebo, Capsaicinoids/Capsinoids significantly increased RMR (WMD: 33.99 Kcal/day, 95% CI: 15.95, 52.03; I2 : 0%, p = .94), energy expenditure, and fat oxidation. It also significantly lessened RQ (WMD: -0.01, 95% CI: -0.02, -0.01; I2 : 5.4%, p = .39) and carbohydrate oxidation. Moreover, intervention in capsule form for longer duration had a more considerable influence on RMR than comparative groups. We observed moderate improvement in RMR, RQ, and fat oxidation following supplementation with Capsaicinoids/Capsinoids. However, further high-quality studies are required to clarify the thermogenic properties of Capsaicinoids/Capsinoids.

Effectiveness of dry needling for improving pain and disability in adults with tension-type, cervicogenic, or migraine headaches: protocol for a systematic review.

Background: Headache is the most common neurological symptoms worldwide, as over 90% of people have noted at least one headache during their lifetime. Tension-type headaches, cervicogenic headaches, and migraines are common types of headache which can have a significant impact on social, physical, and occupational functioning. Therapeutic management of headaches mainly includes physical therapy and pharmacological interventions. Dry needling is a relatively new therapeutic approach that uses a thin filiform needle without injectate to penetrate the skin and stimulate underlying tissues for the management of neuromusculoskeletal pain and movement impairments.The main objective of this systematic review and meta-analysis is to evaluate the effectiveness of dry needling in comparison to other interventions on pain and disability in patients with tension-type headache, cervicogenic headache, and migraine. Methods/design: We will focus on clinical trials with concurrent control group(s) and comparative observational studies assessing the effect of dry needling in patients with tension-type headache, cervicogenic headache, and migraine. Electronic databases from relevant fields of research (PubMed/ Medline, Scopus, Embase®, PEDro, Web of Science, Ovid, AMED, CENTRAL, and Google Scholar) will be searched from inception to June 2019 using defined search terms. No restrictions for language of publication or geographic location will be applied. Moreover, grey literature, citation tracking, and reference lists scanning of the selected studies will be searched manually. Primary outcomes of this study are pain intensity and disability, and secondary outcomes are cervical spine ROM, frequency of headaches, health-related quality of life, and TrPs tenderness. Studies will be selected by three independent reviewers based on prespecified eligibility criteria. Three reviewers will independently extract data in each eligible study using a pre-piloted Microsoft Excel data extraction form. The assessment of risk of bias will be implemented using the Cochrane Back and Neck Review Group 13-item criteria and NOS. Direct meta-analysis will be performed using a fixed or random effects model to estimate effect size such as standardized mean difference (Morris's dppc ) and 95% confidence intervals. Statistical heterogeneity will also be evaluated using the I2 statistic and the χ2 test. All meta-analyses will be performed using Stata V.11 and V.14 softwares. The overall quality of the evidence for the primary outcomes will be assessed using GRADE. Discussion: All analyses in this study will be based on the previous published papers. Therefore, ethical approval and patient consent are not required. The findings of this study will provide important information on the value of dry needling for the management of tension-type headache, cervicogenic headache, and migraine.

Can coenzyme Q10 supplementation effectively reduce human tumor necrosis factor-α and interleukin-6 levels in chronic inflammatory diseases? A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND/OBJECTIVE: Systematic inflammation plays a major role in all stages of chronic diseases. Recent evidence suggests that Coenzyme Q10 (CoQ10), as an anti-inflammatory agent, has shown beneficial effects on the inflammatory process of various human diseases. However, several trials have examined the effects of CoQ10 on pro-inflammatory cytokines with contrasting results. The objective of this systematic review and meta-analysis of randomized clinical trials (RCTs) was to assess the efficacy of CoQ10 supplementation on tumor necrosis factor- α (TNF-α) and interleukin-6 (IL-6) levels. MATERIALS AND METHODS: A systematic literature was performed on databases including PubMed/Medline, EMBASE, Web of Science, SCOPUS, Cochrane Library databases, Clinical Trials.gov and historical search of reference lists from selected studies up to December 2018. Two reviewers independently investigated study eligibility, extracted data, and assessed risk of bias of relevant studies using a standardized protocol. Heterogeneity was measured by the I2 statistic. Data were pooled, using the fix or random-effect model based on the heterogeneity test results and the efficacy of CoQ10 expressed as the standardized mean difference (SMD) with 95% confidence interval (CI). Random-effects meta-regression was done to examine the effect of putative confounders or potential moderators on TNF-α and IL-6 levels. RESULTS: Overall, nine RCTs with a total of 509 patients (269 in the CoQ10 arm and 240 in the control arm) provided the inclusion criteria and were included in the analysis. Our meta-analysis indicated that oral CoQ10 supplementation (60-500 mg/day for 8-12 weeks) resulted in significant reduction of TNF-α (SMD: -0.44, 95% CI: [-0.81 to -0.07] mg/dl; I2 = 66.1%, p  = 0.00) and IL-6 levels (SMD: -0.37, 95% CI: [-0.65 to -0.09]; I2 = 57.2, p  = 0.01), respectively. Subgroup analyses represented a significant reduction of TNF-α and IL-6 levels in patients with BMI < 26. Due to the small number of studies and patients included in each subgroup, these subgroup analyses need to be interpreted cautiously. CONCLUSION: This meta-analysis of RCTs reported a significant effect of CoQ10 on some of the inflammatory markers among patients with chronic diseases which could attenuate the inflammatory state. However, well-designed studies with a larger sample size are required. Note that the results should be interpreted with caution because of the evidence of heterogeneity and limited number of studies.

Can coenzyme Q10 supplementation effectively reduce human tumour necrosis factor-α and interleukin-6 levels in chronic diseases? Protocol for a systematic review and meta-analysis of randomised controlled trials.

INTRODUCTION: Inflammation, as a critical factor, can cause numerous chronic diseases by creating various proinflammatory cytokines. Coenzyme Q10 (CoQ10) can potentially exert an anti-inflammatory agent; in turn, this agent can reduce the systemic inflammatory response. The aims of this study are to conduct a comprehensive systematic review and a meta-analysis for the determination of the CoQ10 efficacy on the changes in serum interleukin-6 (IL-6) and the tumour necrosis factor-α (TNF-α) levels in unhealthy subjects. METHOD AND ANALYSIS: We will conduct an electronic search for articles published between January 1990 and January 2017 using a prespecified search strategy in MEDLINE, SCOPUS, EMBASE, CENTRAL and Web of Science.Our search will focus only on randomised controlled clinical trials in unhealthy subjects that employ either a parallel or a crossover design; this search will involve concurrent control groups. The primary outcomes of the literature are to determine the CoQ10 efficacy on the changes in the serum IL-6 and the TNF-α levels in unhealthy subjects. Secondary outcomes such as body mass index, serum adiponectin and high-sensitivity C-reactive protein levels, lipid profile and the heterogeneity assessment of the primary studies will be evaluated. The stages of screen articles, the extracts of relevant data and the assessment of study quality using the Cochrane risk of bias tool will be conducted independently by the two reviewers. Any disagreement will be resolved by discussion with a third person. If the number of eligible studies is sufficient, we will carry out a meta-analysis according to both outcomes. ETHICS AND DISSEMINATION: This study is the protocol for a systematic review and no ethics approval is needed. The findings from the full systematic review will be published in a peer-reviewed journal, and they will also be exhibited at national/international academic and clinical conferences. TRIAL REGISTRATION NUMBER: CRD42016052200.

Estimating the avoidable burden of certain modifiable risk factors in osteoporotic hip fracture using Generalized Impact Fraction (GIF) model in Iran.

BACKGROUNDS: The number of hip fractures, the most common complication of osteoporosis, has increased rapidly over the past decades. The goal of this study is to estimate the avoidable burden of certain modifiable risk factor of the condition using the Generalized Impact Fraction (GIF) model, which has been suggested and used by epidemiologists to overcome the drawbacks associated with the use of Attributable Fraction index. In addition to preventing a risk factor or the avoidable fraction of burden, this index can also calculate the change in the burden, when a risk factor is altered. METHODS: International databases were searched through PubMed, CINAHLD, Embase using OVID and Google scholar. National resources were searched through IranDoc, IranMedex, SID and Journal sites. Other resources include abstract books and articles sent to the IOF congress. The following search strategy was used: ("Osteoporotic fracture" OR "Fragility Hip fracture" OR "Calcium" OR "vitamin D" OR "BMI" OR "lean body weight" OR "Physical activity" OR "exercise" OR "Smoke") AND ("prevalence" OR "incidence" OR "relative risk") and limited to "humans." RESULTS: With regards to different scenarios already explained in modifying the studied risk factors, the greatest impact in reducing the prevalence of risk factors on osteoporotic hip fractures, was seen in low serum vitamin D levels, low physical activity and low intake of calcium and vitamin D, respectively. According to the fact that interventions for low serum vitamin D and low intake of calcium and vitamin D, are related to each other, it can be concluded that implementing interventions to change these two risk factors, in the easy, moderate and difficult scenarios, would result in approximately a 5%, 11% and 17% decrease in the burden of osteoporotic hip fractures, respectively. The addition of interventions addressing low physical activity in the easy, moderate and difficult scenarios, an 8%, 21% and 35% reduction in the burden of osteoporotic hip fractures would be reported, respectively. CONCLUSION: Improving serum vitamin D levels, recommending the consumption of calcium and vitamin D supplementations and advocating physical activity are the most effective interventions to reduce the risk of osteoporotic hip fractures.

Characteristics of high-risk sexual behaviors for human immunodeficiency virus infection among Iranian drug abusers.

OBJECTIVES: This study was conducted to estimate the prevalence and the associated factors of high-risk sexual behaviors among drug abusers referred to a methadone clinic in Gorgan, the capital of Golestan province in the northeast of Iran, to help health care decision makers on designing interventional programs. METHODS: In this cross-sectional study, 400 drug abusers referred to our methadone clinic were evaluated for high-risk sexual behavior. A logistic regression model was fitted for the association between independent variables and high-risk sexual behavior. RESULTS: Approximately a quarter of patients (25.5%) had high-risk sexual behavior among which 47% had not used a condom in their last sexual contact. Drug abusers who had poor economic status had a lower chance of high-risk sexual behavior than those with good economic status (adjusted odds ratio [AOR] = 0.35, 95% confidence interval [CI] = 0.13-0.96). Also, 1-year increase in age reduced the chance by 6% (AOR = 0.94, 95% CI = 0.91-0.98). Heroin abusers, compared with opium abusers, had a duplicated chance of having high-risk sex (AOR = 2.11, 95% CI = 1.12-3.96). CONCLUSION: According to this study, high-risk sexual behavior in the drug abusers referred to methadone clinic was associated with younger age, good economic status, and heroin addiction. Hence, in interventional planning, more attention should be paid to young drug abusers, patients with good economic status, and heroin addicts as well.

Effects of Vitamin E and Zinc Supplementation on Antioxidants in Beta thalassemia major Patients.

OBJECTIVE: In beta thalassemic patients, tissue damage occurs due to oxidative stress and it happens because of the accumulation of iron in the body. This study was conducted to determine the effect of zinc and vitamin E supplementation on antioxidant status in beta-thalassemic major patients. METHODS: This double blind randomized clinical trial was carried out on 120 beta thalassemic patients older than 18 years. Patients were randomly categorized in four groups. Zinc (50mg/day) and vitamin E (400mg/day) supplements were administered for former and latter group, respectively. In the third group both supplements were administered in similar doses. The fourth (control) group received no supplement. The effect of supplementations on serum zinc and vitamin E, superoxide dismutase (SOD), glutathione peroxidase (GPX), total antioxidant capacity (TAC) and body mass index (BMI) were measured at the beginning and the end of the study. FINDINGS: Serum zinc levels in group 1 and 3 were significantly increased (P<0.007 and P<0.005, respectively). Serum vitamin E levels in group 2 and 3 were also increased significantly (P<0.001). Mean GPX activity in group1, 2 and 3 decreased significantly (P<0.015, P<0.032 and P<0.029, respectively). Mean SOD activity and TAC did not show significant change after supplementation. BMI had significant increase in all treated groups (P<0.001). CONCLUSION: Our results suggest that beta thalassemic patients have enhanced oxidative stress and administration of selective antioxidants may preclude oxidative damage.

Soils selenium level and esophageal cancer: an ecological study in a high risk area for esophageal cancer.

PROJECT: Golestan province, located in northeast of Iran, has been known as a high risk area for esophageal cancer (EC). This study was conducted to assess the relationship between soils selenium (Se) level and development of EC in this region. PROCEDURES: In this ecological study, 135 blocks were identified in Golestan province based on geographical altitude and longitude on the map. One soil sample was collected from the center of each block. Then we investigated Se concentration in soil samples by flame atomic absorption spectrometry. Statistical analysis was performed by the Pearson correlation test and Student t-tests. P-values of less than 0.05 were considered as significant. RESULTS: The mean+/-SD of soils Se level in Golestan province was 3.7+/-1.61 mg/kg. There was a positive correlation between soils Se level and EC rates in this area (P=0.03) (Pearson correlation coefficient=0.19). Soils Se concentration was significantly higher in high (4.13 mg/kg) than in the low (3.39 mg/kg) EC rate areas (P=0.01). CONCLUSIONS: We found high soils Se concentration and a significant positive relationship between soils Se level and EC rate in Golestan province of Iran. So, high soils Se level may play a possible role in developing EC in this area, specifically in Turkmensahra (very high EC rates).
