Association between bronchopulmonary dysplasia and cerebral palsy in children: a meta-analysis

ObjectiveTo investigate the association between bronchopulmonary dysplasia (BPD) and the risk of cerebral palsy (CP) in children.Data sourcesWe used EMBASE, PubMed and Web of Science to conduct a meta-analysis of studies published before 1 September 2017, written in English whose titles or abstracts discussed an association between BPD and CP.Study selectionObservational studies, for example, case–control and cohort studies were included.Data extraction and synthesisAll review stages were conducted by two reviewers independently. Data synthesis was undertaken via meta-analysis of available evidence.Main outcomes and measuresThe prevalence of developing CP was measured after exposure to BPD.ResultsAmong 1234 initially identified studies, we selected those that addressed an association between BPD and CP according to our preselected inclusion criteria. Our meta-analysis included 11 studies. According to a random effect model, BPD was significantly associated with CP (ORs 2.10; 95% CI 1.57 to 2.82) in preterm infants. Factors explaining differences in the study results included study design, the definition of BPD, the time of diagnosis of CP and whether the studies adjusted for potential confounders.ConclusionThis study suggests that BPD is a risk factor for CP. Further studies are required to confirm these results and to detect the influence of variables across studies.

Capgras Syndrome

ABSTRACT The association between Capgras syndrome and Alzheimer’s disease has been reported in several studies, but its prevalence varies considerably in the literature, making it difficult to measure and manage this condition. Objective: This study aims to estimate the prevalence of Capgras syndrome in patients with Alzheimer’s disease through a systematic review, and to review etiological and pathophysiological aspects related to the syndrome. Methods: A systematic review was conducted using the Medline, ISI, Cochrane, Scielo, Lilacs, and Embase databases. Two independent researchers carried out study selection, data extraction, and qualitative analysis by strictly following the same methodology. Disagreements were resolved by consensus. The meta-analysis was performed using the random effect model. Results: 40 studies were identified, 8 of which were included in the present review. Overall, a total of 1,977 patients with Alzheimer’s disease were analyzed, and the prevalence of Capgras syndrome in this group was 6% (CI: 95% I² 54% 4.0-8.0). Conclusion: The study found a significant prevalence of Capgras syndrome in patients with Alzheimer’s disease. These findings point to the need for more studies on the topic to improve the management of these patients.

ABSTRACTObjective:Hemodynamic instability following emergent endotracheal intubation (EETI) is a potentially life-threatening adverse event. The objectives of this systematic literature review were to document the incidence of postintubation hemodynamic instability (PIHI), to determine the definitions for PIHI used in the available literature, and to examine factors associated with PIHI in adult patients who require EETI.Data Source:Articles published in Medline (1966–August 2012).Study Selection:This systematic review included adult, inhospital studies of EETIs. Studies with nonemergent or pediatric patient populations were excluded.Data Extraction:Two authors independently performed data abstraction. Disagreements were resolved by a third party. The methodological quality of included studies was assessed with the Newcastle-Ottawa Quality Assessment Scale for Cohort Studies.Data Synthesis:We estimated the pooled prevalence of PIHI across studies using a random effects meta-analysis. Subgroups analyzed included study design, intubation setting, geographic location of the study, physician experience, medications used for sedation, neuromuscular blockade, and definition of PIHI. Eighteen studies were analyzed, with sample sizes from 84 to 2,833 patients. The incidence of PIHI ranged from 5 to 440 cases per 1,000 intubations, with a pooled estimate of 110 cases per 1,000 intubations (95% CI 65–167).Conclusions:PIHI was found to occur in 110 cases per 1,000 in-hospital, emergent intubations. However, heterogeneity among the included studies limits the reliability of this summary estimate. Further investigation is warranted.

BackgroundMany studies explored the use of simulation in basic surgical education, with a variety of devices, contexts and outcomes, with sometimes contradictory results.ObjectivesThe objectives of this meta-analysis were to focus the effect that the level of physical resemblance in a simulation has on the development of basic surgical skill in undergraduate medical students and to provide a foundation for the design and implementation of a simulation, with respect to its effectiveness and alignment with the learning outcomes.Study selectionWe searched PubMed and Scopus database for comparative randomised studies between simulations with a different level of resemblance. The result was synthesised as the standardised mean difference, under a random effect model.FindingsWe selected 12 out of 2091 retrieved studies, reporting on 373 undergraduate students (mean of subjects 15.54±6.89). The outcomes were the performance of simple skills and the time to complete a task. Two studies reported a scoring system; seven studies reported time for a task; and three studies reported both. The total number of measures included in the meta-analysis was 456 for score and 504 for time. The pooled effect size did not show any significant advantage in a simulation of a high level of physical resemblance over a lower level, both for the scoring system (−0.19, 95% CI −0.44 to 0.06) and for time (−0.14, 95% CI −0.54 to 0.27).ConclusionSimulations with a low level of physical resemblance showed the same effect as the simulation using a higher level of resemblance on the development of basic surgical skills in undergraduate students.

ABSTRACT Objective: To compare efficacy and safety of vancomycin versus teicoplanin in patients with proven or suspected infection. Methods: Data Sources: Cochrane Renal Group's Specialized Register, CENTRAL, MEDLINE, EMBASE, nephrology textbooks and review articles. Inclusion criteria: Randomized controlled trials in any language comparing teicoplanin to vancomycin for patients with proven or suspected infection. Data extraction: Two authors independently evaluated methodological quality and extracted data. Study investigators were contacted for unpublished information. A random effect model was used to estimate the pooled risk ratio (RR) with 95% confidence interval (CI). Results: A total of 24 studies (2,610 patients) were included. The drugs had similar rates of clinical cure (RR: 1.03; 95%CI: 0.98-1.08), microbiological cure (RR: 0.98; 95%CI: 0.93-1.03) and mortality (RR: 1.02; 95%CI: 0.79-1.30). Teicoplanin had lower rates of skin rash (RR: 0.57; 95%CI: 0.35-0.92), red man syndrome (RR: 0.21; 95%CI: 0.08-0.59) and total adverse events (RR: 0.73; 95%CI: 0.53-1.00). Teicoplanin reduced the risk of nephrotoxicity (RR: 0.66; 95%CI: 0.48-0.90). This effect was consistent for patients receiving aminoglycosides (RR: 0.51; 95%CI: 0.30-0.88) or having vancomycin doses corrected by serum levels (RR: 0.22; 95%CI: 0.10-0.52). There were no cases of acute kidney injury needing dialysis. Limitations: Studies lacked a standardized definition for nephrotoxicity. Conclusions: Teicoplanin and vancomycin are equally effective; however the incidence of nephrotoxicity and other adverse events was lower with teicoplanin. It may be reasonable to consider teicoplanin for patients at higher risk for acute kidney injury.

AbstractBackgroundHypertension is a common public health problem worldwide and is a well-known risk factor for increased risk of cardiovascular diseases, contributing to high morbidity and mortality. However, there is no systematic review and meta-analysis that has been done in a multi-ethnic population like Malaysia. This systematic review aims to determine the trend in prevalence, awareness and control of hypertension in Malaysia.MethodsSystematic searches were conducted in PubMed, Scopus, Ovid, Cumulative Index to Nursing and Allied Health Literature, Malaysian Medical Repository and Malaysia Citation Index published between 1980 and 2017. All original articles in English were included. Studies included were those on adults aged 18 years and above. Studies of prevalence in children and adolescents and pregnancy related hypertension were excluded. Two authors independently reviewed the studies, carried out data extraction and performed quality assessment. Heterogeneity between studies and publication bias was assessed and effect size was pooled by the random effect model.ResultsFifty-six studies with a total of 241,796 subjects were included. The prevalence of hypertension throughout Malaysia varied (I2= 99.3%). The overall pooled prevalence of hypertension over the past 4 decades was 28.2% in adults aged 18 years and older (95% CI: 26.1 – 33.3) and the prevalence in those 30 years and older was 40.0% (95% CI: 35.3-44.8).For subgroup analysis, the prevalence of hypertension in male aged 18 and above was 31.4% (95% CI: 26.5 - 36.2) and 27.8% in female (95% CI: 20.7 – 34.9). The prevalence of hypertension among the ethnic groups aged 18 years and above were 37.3% in Malays (95% CI: 32.9 – 41.7); 36.4% in Chinese (95% CI 31.6 - 41.2) and 34.8% in Indians (95% CI: 31.2-38.4). The prevalence of hypertension was the lowest in the 1980s (16.2%, 95% CI: 13.4-19.0%), increases up to 36.8% in the 1990s (95% CI: 6.1-67.5), then came down to 28.7% (95% CI: 21.7-35.8) in the 2000s and 29.2% (95% CI: 24.0-34.4) in the 2010s. The prevalence of awareness was 38.7% (95% CI: 31.7 – 45.8) whereas the control of hypertension of those on treatment was 33.3% (95% CI: 28.4 – 38.2).ConclusionThree in 10 adults aged 18 years old and above have hypertension, whereas four in 10 adults aged 30 years old and above have hypertension. Four out of 10 are aware of their hypertension status and only one-third of them who were under treatment achieved control of their hypertension. Concerted efforts by policymakers and healthcare professionals to improve the awareness and control of hypertension should be of high priority.

Efficacy And Safety

Background: Obesity is a real burden and its prevalence is constantly increasing. High body weight is a risk factor for developing venous thromboembolism (VTE). Direct oral anticoagulants’ (DOAC) pharmacokinetics and pharmacodynamics are affected by obesity. Their efficacy and safety in obese (BMI ≥30kg/m 2 ) and morbidly obese (BMI ≥40kg/m 2 ) patients are still unclear in the treatment of VTE. Objectives: To compare the efficacy and safety of DOAC with vitamin K antagonist (VKA)/low molecular weight heparin (LMWH) in the acute treatment of VTE in obese and morbidly obese patients. The primary efficacy outcome was VTE recurrences. The safety outcomes were major bleeding (MB) and clinically relevant non-MB (CRNMB). All-cause mortality was also assessed. Hypothesis: We hypothesized that DOAC would present the same efficacy and safety for the treatment of acute VTE in obese and morbidly obese patients compared to VKA/LMWH. Methods: A systematic literature search (MEDLINE, EMBASE, CENTRAL, Web of Science) was conducted from inception to April 15 th 2020, identifying trials studying DOAC in the treatment of acute VTE in obese patients. Studies were included if one of the outcomes was reported. Two independent reviewers performed the study selection, data extraction, risk of bias assessment and strength of body evidence evaluation using the GRADE methodology. Analyses were conducted using the Mantel-Haenszel method based on a random-effect model. Relative risks (RR) were estimated for the effect measure with 95% confidence intervals. Results: From 1240 citations screened, we included 21 studies (58,590 patients). VTE recurrences was similar with DOAC compared to VKA/LMWH in obese patients (risk ratio (RR): 1.03; 95%CI 0.93-1.15; p=0.55) and morbidly obese patients (RR 1.06; 95CI 0.94-1.19; p=0.35). DOAC was associated with a reduction in MB in obese patients (RR 0.57; 95%CI 0.34-0.94; p=0.03) and morbidly obese patients (RR 0.71; 95%CI 0.50-1.00; p=0.05) compared to VKA/LMWH. In obese patients, no difference was observed in CRNMB with DOAC compared to VKA/LMWH. Conclusion: DOAC is as effective in reducing VTE and is associated with less MB compared to VKA/LMWH in obese and morbidly obese patients.

The Relationship

Introduction: Diabetes is the most common endocrine disease that annually causes four million deaths in the world. It is not just a disease, however a series of metabolic disorders caused by defects in insulin secretion, insulin action, or both. Considering the importance of diet in the incidence and complications of diabetes, this study aimed to investigate the relationship between the dietary acid load with diabetes, which has recently been considered. Methods: This meta-analysis was first performed as a systematic review by searching in Google Scholar, Science Direct, PubMed, Wiley, Directory of Open Access Journals (DOAJ), Springer, Cochrane, ProQuest, and Scopus, as well as domestic databases including Magiran, SID, Irandoc, and Google Scholar. A total of 1511 articles were found that after reviewing and excluding irrelevant articles, five were included in the study. Results: In the present study, a significantly high heterogeneity was observed (I2 = 61.5, P = 0.01). A random effect model was used and the studies were weighted using the inverse-variance method. The odds ratio (OR) obtained from the meta-analysis was 1.17 (1.12-1.22). Examination of publication bias showed that the studies were symmetrically distributed in the funnel plot. Egger’s and Begg’s tests were also performed that showed no evidence for the existence of publication bias [Egger’s test (P ≥ 0.79) and Begg’s test (P ≥ 0.69)]. Conclusion: The results of the present meta-analysis showed a significant relationship between dietary acid load and the incidence of diabetes. This result is similar to most studies on the subject, except for one study, which was limited to the elderly male population. The number of studies in the present meta-analysis was low due to the limited number of research in this field.

ABSTRACTObjectivesTo systematically review the literature on the prevalence of dental fear in adults to estimate a worldwide pooled prevalence and to investigate factors related to the heterogeneity of estimates.MethodsInclusion criteria were population-based studies reporting the prevalence or data that allowed the calculation of prevalence of dental fear in adults and/or elders. Five electronic databases (Embase, PubMed, Scopus, Virtual Health Library (BVS) and Web of Science) were searched. Two researchers independently performed the study selection, data extraction and quality assessment of the included studies. The prevalence pooled estimates of dental fear were calculated using fixed- and random-effect models. Subgroup analyses were performed to investigate variability between studies.ResultsThe search strategy identified 4,486 studies. After removal of duplicates (1,722), title and abstract screening (2,764) and full-text reading (108), 31 publications were deemed eligible for this systematic review. A total of 72,577 individuals 18 years of age or older composed the sample of this systematic review. The global estimated prevalence of dental fear and anxiety (DFA), high DFA and severe DFA in adults were 13.8%, 11.2% and 2.6%, respectively. Subgroup analyses showed a higher prevalence of DFA, high DFA and severe DFA among women and younger adults. The instrument used to measure dental fear also affected the prevalence of the outcome.ConclusionsDental fear and high dental fear are prevalent in adults worldwide, being more prevalent among women.
