BACKGROUND: Subdural hematoma is a common phenomenon following a traumatic brain injury where a hematoma is formed below the dura mater of brain meningeal layer, usually with a coup-contrecoup mechanism of injury. The chronic counterpart of subdural hematoma is frequently occurring in elderly patients. There are several techniques being used by many practitioners, including burr hole with or without irrigation, with little evidence of which technique is favorable, especially in terms of recurrence rates following the procedure. AIM: This study aimed to compare the recurrences of chronic subdural hematoma (CSDH) following burr hole with and without saline irrigation technique by systematic review and meta-analysis. METHODS: This study included all articles that describe the two specified burr hole techniques in treating patients with a CSDH. We extracted the eligibility criteria into keywords using Boolean Operator. In this study, we used keywords (CSDH) and (burr hole) and (irrigation) and ((drainage) or no irrigation)) in PubMed, directory of open access journal, and Google Scholar database. RESULTS: This study included seven retrospective cohort studies from 2002 to 2017 with a total of 635 samples. The incidence of hematoma recurrences between burr hole irrigation and burr hole drainage was 14.7% and 12.0%, respectively. Based on random effect model with high heterogeneity (I2 = 60%; X2 = 14.92; p = 0.02), pooled risk ratio between burr hole irrigation and burr hole drainage on hematoma recurrences was 1.05 (p = 0.92; 95% confidence interval, 0.43–2.54). CONCLUSION: There was no superiority between one procedure toward other in preventing recurrences of chronic subdural hematoma.

BACKGROUND: Acute subdural hematoma (ASDH) is a major problem in traumatic brain injury. Surgical techniques for treating ASDH are varied, including cranioplastic craniotomy and large decompressive craniectomy. The superiority of craniectomy and craniotomy for treating ASDH is still controversial. AIM: The aim of this study was to compare the clinical outcome between craniectomy and craniotomy for treating traumatic ASDH through systematic review and meta-analysis. METHODS: This study used electronic articles published in PubMed, EBSCO, Google Scholar, and Directory of Open Access Journal. Articles included were full-text observational studies in Indonesian or English. Clinical outcome using the Glasgow Outcome Scale was compared between craniectomy and craniotomy. Statistical analysis was done using Review Manager 5.3. RESULTS: Six articles met our inclusion and exclusion criteria. We performed random effect model analysis because of high heterogeneity between studies (I2 = 77%; X2 = 21.98). The pooled risk ratio between craniectomy and craniotomy on poor outcomes was 1.41 (p = 0.02; 95% CI: 1.06–1.88). CONCLUSION: Craniectomy increases the risk of poor clinical outcomes in treating a traumatic ASDH.

Abstract:Objective and Design:There is controversy among neurosurgeons regarding whether double burr hole craniostomy (DBHC) is better than single burr hole craniostomy (SBHC) in the treatment of chronic subdural hematoma (CSH), in terms of having a lower revision rate. In order to compare the revision rates after SBHC versus DBHC, we performed a meta-analysis of the available studies in the literature.Materials and Methods:Multiple electronic health databases were searched to identify all the studies published between 1966 and December 2010 that compared SBHC and DBHC. Data were processed in Review Manager 5.0.18. Effect sizes were expressed in pooled odds ratio (OR) estimates, and due to heterogeneity between studies we used random effect of the inverse variance weighted method to perform the meta-analysis.Results:Five observational retrospective cohort studies were identified: four published studies and one unpublished, describing the outcomes of 355 DBHC and 358 SBHC to evacuate 713 CSH in 631 patients. Meta-analysis showed that there was no significant difference in the revision rates between double burr hole craniostomy and single burr hole craniostomy when performed to evacuate CSH. Pooled odds ratio for all the studies was 0.62 (95% confidence interval 0.26 - 1.46).Conclusions:The results of this meta-analysis suggest that SBHC is as good as DBHC in evacuating chronic subdural hematoma and is not associated with a higher revision rate compared to DBHC.

Balance problems are one of the most frequent symptoms in patients with Fibromyalgia Syndrome (FMS). However, the extent and nature of this balance disorder are not known. The objective of this work was to determine the best evidence for the alteration of postural balance in patients with FMS and analyze differences with healthy controls. To meet this objective, a systematic review with meta-analysis was performed. A bibliographical search was carried out in PubMed Medline, Scopus, Web of Science, CINAHL and SciELO. Observational studies that assessed postural balance in patients with FMS compared to healthy subjects in baseline conditions, were selected. In a random-effect model, the pooled effect was calculated with the Standardized Mean Difference (SMD) and its 95% confidence interval (CI). Nineteen studies reporting data of 2347 participants (95% female) were included. FMS patients showed poor balance with a large effect on static (SMD = 1.578; 95% CI = 1.164, 1.992), dynamic (SMD = 0.946; 95% CI = 0.598, 1.294), functional balance (SMD = 1.138; 95% CI = 0.689, 1.588) and on balance confidence (SMD = 1.194; 95% CI = 0.914, 1.473). Analysis of the Sensory Organization Test showed large alteration of vestibular (SMD = 1.631; 95% CI = 0.467, 2.795) and visual scores (SMD = 1.317; 95% CI = 0.153, 2.481) compared to healthy controls. Patients with FMS showed worse scores for different measures of postural balance compared to healthy controls. Concretely, FMS patients appear to have poor vestibular and visual scores with a possible somatosensory dependence.

Abstract Background Neural tube defects (NTDs) are a group of disorders that arise from the failure of the neural tube close between 21 and 28 days after conception. About 90% of neural tube defects and 95% of death due to these defects occurs in low-income countries. Since these NTDs cause considerable morbidity and mortality, this study aimed to determine the prevalence and associated factors of NTDs in Africa. Methods The protocol of this study was registered in the International Prospective Register of Systematic Reviews (PROSPERO number: CRD42020149356). All major databases such as PubMed/MEDLINE, EMBASE, CINAHL, Web of Science, African Journals Online (AJOL), and Google Scholar search engine were systematically searched. A random-effect model was used to estimate the pooled prevalence of NTDs in Africa, and Cochran’s Q-statistics and I2 tests were used to assess heterogeneity between included studies. Publication bias was assessed using Begg ’s tests, and the association between determinant factors and NTDs was estimated using a random-effect model. Results Of the total 2679 articles, 37 articles fulfilled the inclusion criteria and were included in this systematic review and meta-analysis. The pooled prevalence of NTDs in Africa was 50.71 per 10,000 births (95% CI: 48.03, 53.44). Folic acid supplementation (AOR: 0.40; 95% CI: 0.19–0.85), maternal exposure to pesticide (AOR: 3.29; 95% CI: 1.04–10.39), mothers with a previous history of stillbirth (AOR: 3.35, 95% CI: 1.99–5.65) and maternal exposure to x-ray radiation (AOR 2.34; 95% CI: 1.27–4.31) were found to be determinants of NTDs. Conclusions The pooled prevalence of NTDs in Africa was found to be high. Maternal exposure to pesticides and x-ray radiation were significantly associated with NTDs. Folic acid supplementation before and within the first month of pregnancy was found to be a protective factor for NTDs.

Risk Of Recurrence

Objective Chronic subdural hematoma (CSDH) is a common and debilitating neurological condition whose treatments, including burr hole drainage and craniotomy, suffer from high rates of recurrence and complication. Embolization of the middle meningeal artery (EMMA) is a promising minimally invasive approach to manage CSDH in a broad set of patients. Methods To evaluate the efficacy and safety of EMMA, a database search was conducted including the terms “subdural hematoma; embolization; embolized; middle meningeal” was performed and yielded a total of 260 results. Following exclusion based on predefined criteria, a total of four studies were identified and outcomes including recurrence rates and complication rates were extracted for analysis. Results Four studies including intervention and control groups were included with a total of n = 888 patients. The relative risk of CSDH recurrence in the EMMA (3.5%) compared to control group (23.5%) was significantly reduced when EMMA was performed (risk ratio = 0.17; 95% confidence interval (CI) 0.05–0.67). In addition, rates of complication were not significantly different between patients with conventional therapy and those who received EMMA (OR = 0.77; 95 confidence interval (CI) 0.3–1.99). Conclusion Based on limited data, EMMA reduces the risk of recurrence by 20% compared to surgical treatment for CSDH.

Abstract Purpose Cardiotoxicity affects 5–16% of cancer patients who receive anthracyclines and/or trastuzumab. Limited research has examined interventions to mitigate cardiotoxicity. We examined the role of statins in mitigating cardiotoxicity by performing a systematic review and meta-analysis of published studies. Methods A literature search was conducted using PubMed, Embase, Web of Science, ClinicalTrials.gov, and Cochrane Central. A random-effect model was used to assess summary relative risks (RR), weighted mean differences (WMD), and corresponding 95% confidence intervals. Testing for heterogeneity between the studies was performed using Cochran’s Q test and the I2 test. Results Two randomized controlled trials (RCTs) with a total of 117 patients and four observational cohort studies with a total of 813 patients contributed to the analysis. Pooled results indicate significant mitigation of cardiotoxicity after anthracycline and/or trastuzumab exposure among statin users in cohort studies [RR = 0.46, 95% CI (0.27–0.78), p = 0.004, $${ }I^{2}$$ I 2  = 0.0%] and a non-significant decrease in cardiotoxicity risk among statin users in RCTs [RR = 0.49, 95% CI (0.17–1.45), p = 0.20, $$I^{2}$$ I 2  = 5.6%]. Those who used statins were also significantly more likely to maintain left ventricular ejection fraction compared to baseline after anthracycline and/or trastuzumab therapy in both cohort studies [weighted mean difference (WMD) = 6.14%, 95% CI (2.75–9.52), p < 0.001, $$I^{2}$$ I 2  = 74.7%] and RCTs [WMD = 6.25%, 95% CI (0.82–11.68, p = 0.024, $$I^{2}$$ I 2  = 80.9%]. We were unable to explore publication bias due to the small number of studies. Conclusion This meta-analysis suggests that there is an association between statin use and decreased risk of cardiotoxicity after anthracycline and/or trastuzumab exposure. Larger well-conducted RCTs are needed to determine whether statins decrease risk of cardiotoxicity from anthracyclines and/or trastuzumab.

Abstract Background The probability of developing invasive cutaneous malignant melanoma (CMM) is higher in women than in men up until the age of 49. Several studies investigated the association between hormonal factors and CMM. The aim of this systematic review and meta-analysis is to summarize the evidence on the association between Oral Contraceptives (OC) and the risk of CMM. Methods This review and meta-analysis follow the PRISMA guidelines. A systematic literature search was conducted on Medline and Web of Science until December 2019. Studies were eligible if reported a risk estimate for the association between OC and CMM. Heterogeneity testing was performed using Cochran's Q and I2 statistics. Publication bias was assessed by Egger's test and Begg's test. Meta-analysis was performed using random effect model. Results The results of the pooled analysis of all 32 studies showed no significant association between OC and the risk of CMM (OR 1.02; 95% CI 0.94-1.11; I2=39.32%, p = 0.013). The stratified analyses by study design found no significant association between OC and the risk of CMM neither in the 18 case-control studies (OR 1.02; 95% CI 0.87-1.21; I2=56.91%, p = 0.002) nor in the 14 cohort studies (OR 1.04; 95% CI 0.98-1.11; I2=0.00%, p = 0.557). No significant publication bias could be detected by Egger's test or Begg's test. Conclusions This meta-analysis of available literature suggests no significant association between OC and the risk of developing CMM. Further investigations are needed to evaluate the possible relationship of OC use and other hormonal factors potentially contributing to the increased risk of CMM in women during their reproductive years. Key messages Oral contraceptives (OC) do not significantly contribute to the risk of Cutaneous Malignant Melanoma (CMM). Further studies are needed to investigate the potential role of other hormonal factors in the increased probability of developing CMM in women during their reproductive years.
