Prevalence of Intracranial Aneurysm in Patients with Aortopathy: A Systematic Review with Meta-Analyses

Background and Purpose Patients with aortic disease might have an increased risk of intracranial aneurysm (IA). We conducted this research to assess the prevalence of IA in patients with aortopathy, considering the impact of gender, age, and cardiovascular risk factors.Methods We searched PubMed and Scopus from inception to August 2019 for epidemiological studies reporting the prevalence of IA in patients with aortopathy. Random-effect meta-analyses were performed to calculate the overall prevalence, and the effect of risk factors on the prevalence was also evaluated. Anatomical location of IAs in patients suffered from distinct aortic disease was extracted and further analyzed.Results Thirteen cross-sectional studies involving 4,041 participants were included in this systematic review. We reported an estimated prevalence of 12% (95% confidence interval [CI], 9% to 14%) of IA in patients with aortopathy. The pooled prevalence of IA in patients with bicuspid aortic valve, coarctation of the aorta, aortic aneurysm, and aortic dissection was 8% (95% CI, 6% to 10%), 10% (95% CI, 7% to 14%), 12% (95% CI, 9% to 15%), and 23% (95% CI, 12% to 34%), respectively. Gender (female) and smoking are risk factors related to an increased risk of IA. The anatomical distribution of IAs was heterogeneously between participants with different aortic disease.Conclusions According to current epidemiological evidence, the prevalence of IA in patients with aortic disease is quadrupled compared to that in the general population, which suggests that an early IA screening should be considered among patients with aortic disease for timely diagnosis and treatment of IA.

The Impact

Background: Well-established risk factors for fertility problems such as smoking have been included in fertility awareness efforts globally. However, these efforts neglect risks that women in low and middle-income countries (LMIC) face. Objective: To address this gap, we identified eight risk factors affecting women in LMIC and the aim of the current review was to estimate the impact of these risks on fertility. Methods: We conducted systematic reviews and where data was available meta-analyses. We searched Medline, Embase, Cochrane library, regional databases and key organizational websites (1946-June 2016, updated January 2018, latest update taking place in 2021). Two researchers screened and extracted data independently. We included all study designs that assessed exposure to risk in clinical or community-based samples and excluded studies without control groups. The outcome of interest was fertility problems (inability to achieve pregnancy or live birth and neonatal death). We calculated pooled effect estimates from reported effect sizes or raw data. We assessed study quality using the Newcastle-Ottawa Scale. We registered the review with PROSPERO, registration number CRD42016048497. Results: We identified 2,418 studies and included 61 (57 in meta-analyses). Results revealed a nine-fold increased risk of inability to become pregnant in genital tuberculosis (OR 8.91, CI 1.89-42.12) and almost threefold in HIV (OR 2.93, CI 1.95-4.42) and bacterial vaginosis (OR 2.81, CI 1.85-4.27). A twofold increased risk of tubal-factor infertility in Female Genital Mutilation/Cutting [Type II/III] (OR 2.06, CI 1.03-4.15) and increased post-natal mortality in consanguinity (stillbirth, OR 1.28, CI 1.04-1.57; neonatal death, OR 1.57, CI 1.22-2.02). Strength and limitations: Reliability of results was bolstered by a rigorous systematic review methodology that is replicable but limited by methodological shortcomings of the available primary studies and the small number of studies in each meta-analysis. Conclusions: The risk factors investigated appeared to impact the reproductive process through multiple biological, behavioural, and clinical pathways. Additionally, infection and pelvic inflammatory disease seemed to be common pathways for several risk factors. The complex multifactorial risk profile can be addressed by LMIC using a global health framework to determine which risk factors are significant to their populations and how to tackle them. The subsequent health promotion encompassing these relevant health indicators could translate into more prevention and effective early detection of fertility problems in LMIC. Finally, the findings of multifactorial risk reinforced the need to put fertility as an agenda in global health initiatives.

The Impact

Background: Prenatal maternal stress (PNMS) is defined as the experience of significant levels of prenatal stress, depression or anxiety during pregnancy. PNMS has been associated with increased risk of autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD) in exposed offspring. However, these findings are inconsistent and other studies found no association, meaning a clear consensus on the impact of PNMS on ASD and ADHD risk is required. The purpose of this systematic review and meta-analysis is to summarize and critically review the existing literature on the effects of PNMS on ASD and ADHD risk. Methods: Electronic databases (PubMed, PsycINFO, Web of Science, Scopus and EMBASE) will be searched for articles following a detailed search strategy. We will include cohort, case-control and cross-sectional studies that assessed maternal exposure to psychological and/or environmental stress and had ASD or ADHD as an outcome. Two reviewers will independently screen the titles, abstracts and full articles to identify eligible studies. We will use a standardised data extraction form for extracting data and a bias classification tool for assessing study quality. This systematic review will be reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). The generic inverse variance method will be used if possible to perform meta-analyses. Ethics and dissemination: Ethical approval is not required for this study because it will not involve the conduct or inclusion of any experimental or personal data that would require informed consent. The systematic review will be disseminated in peer-reviewed journals. PROSPERO registration number: CRD42018084222.

The Impact

IntroductionThe development of multiple coexisting chronic diseases (multimorbidity) is increasing globally, along with the percentage of older adults affected by it. Multimorbidity is associated with the concomitant use of multiple medications, a greater possibility of adverse effects, and increased risk of hospitalisation. Therefore, this systematic review study protocol aims to analyse the impact of multimorbidity on the occurrence of hospitalisation in older adults and assess whether this impact changes according to factors such as sex, age, institutionalisation and socioeconomic status. This study will also review the average length of hospital stay and the occurrence of hospital readmission.Methods and analysisA systematic review of the literature will be carried out using the PubMed, Embase and Scopus databases. The inclusion criteria will incorporate cross-sectional, cohort and case–control studies that analysed the association between multimorbidity (defined as the presence of ≥2 and/or ≥3 chronic conditions and complex multimorbidity) and hospitalisation (yes/no, days of hospitalisation and number of readmissions) in older adults (aged ≥60 years or >65 years). Effect measures will be quantified, including ORs, prevalence ratios, HRs and relative risk, along with their associated 95% CI. The overall aim of this study is to widen knowledge and to raise reflections about the association between multimorbidity and hospitalisation in older adults. Ultimately, its findings may contribute to improvements in public health policies resulting in cost reductions across healthcare systems.Ethics and disseminationEthical approval is not required. The results will be disseminated via submission for publication to a peer-reviewed journal when complete.PROSPERO registration numberCRD42021229328.

The Impact

The incidence of respiratory disease is increasing. In relation to this, in addition to infection, factors associated with working with chemical insecticides are a cause for concern. Some of the chemicals involved have been shown to affect the respiratory system, and consequentially workers are at increased risk of conditions such as asthma. However, medical opinion around this area is still controversial; therefore, the objective of this study is to investigate the association between exposure to insecticides and asthma by means of a systematic review of the relevant literature. Relevant literature was identified, and a systematic review was conducted to investigate the association between exposure to insecticides and asthma. A total of five studies (three cross sectional and two cohort) including 45,435 subjects were identified as relevant. The summary odds ratios related to the impact of exposure to specific insecticides on asthma were organophosphates 1.31 (95%CI = 1.17–1.48, I2 = 27%, p = 0.172), carbamates 1.44 (95%CI 1.08–1.92, I2 = 56.7%, p = 0.031) and organochlorines 1.31 (95%CI 1.19–1.64, I2 = 37.3%, p = 0.131). Farmers exposed to certain insecticides may have an increased risk of asthma and asthmatic symptoms, but further research on that issue is urgently needed.

Meta Analyses

Globally, increasing rates of obesity are one of the most important health issues. The association between breakfast skipping and body weight is contradictory between cross-sectional and interventional studies. The systematic review and meta-analyses aim to summarize this association based on observational longitudinal studies. We included prospective studies on breakfast skipping and overweight/obesity or weight change in adults. Literature was searched until September 2020 in PubMed and Web of Science. Summary RRs with a 95% CI were estimated in pairwise meta-analyses by applying a random-effects model. In total, 9 studies were included in the systematic review and 6 of them were included in the meta-analyses. The meta-analysis indicated an 13% increased RR for overweight/obesity when breakfast was skipped on ≥ 3 days per week compared to ≤ 2 days per week (95% CI: 1.06, 1.21, n=3 studies). The meta-analysis on weight change displays a 21% increased RR for weight gain for breakfast skippers compared to breakfast eaters (95% CI: 1.05, 1.40, n=2 studies). The meta-analysis on BMI change displayed no difference between breakfast skipping and eating (RR=1.02, 95% CI: 0.99, 1.05, n=2 studies). This study provides low meta-evidence for an increased risk for overweight/obesity and weight gain for breakfast skipping.

Objectives: Gallstone disease shares certain risk factors with cardiovascular disease, particularly metabolic risk factors. Patients with gallstone disease may be at increased risk of cardiovascular disease. Several recent studies exploring the effect of gallstone disease on cardiovascular disease outcomes demonstrated inconsistent results. Design: We conducted a systematic review and meta-analysis of cohort, case–control, and cross-sectional studies that compared the risk of developing cardiovascular disease events in patients with gallstone disease versus non-gallstone disease controls. Data from each study were combined using the random-effects, generic inverse variance method of DerSimonian and Laird to calculate the pooled hazard ratio, odd ratio, and 95% confidence interval. Results: Data were extracted from six studies involving 176,734 cases and 803,714 controls. The pooled hazard ratio of cardiovascular events in patients with gallstone disease was 1.28 (95% confidence interval: 1.23–1.33, I2 = 42%). The pooled odd ratio of cardiovascular events in patients with gallstone disease was 1.82 (95% confidence interval: 1.47–2.24, I2 = 68%). Conclusions: Our study demonstrated a statistically significant increase in the risk of cardiovascular disease among patients with gallstone disease.

Meta Analyses

AbstractWe performed a systematic review and meta-analyses of studies assessing tuberculosis (TB) patient-related risk factors for transmission of Mycobacterium tuberculosis infection. Meta-analyses were conducted for sputum smear-positivity, lung cavitation and HIV seropositivity of index patients with both crude and adjusted odds ratios (AORs) pooled using random effect models. Thirty-seven studies were included in the review. We found that demographic characteristics such as age and sex were not significant risk factors, while behaviours such as smoking and alcohol intake were associated with infectiousness although inconsistently. Treatment delay of >28 days was a significant predictor of greater infectiousness. Contacts of sputum smear-positive index patients were found to be more likely to be infected than contacts of sputum smear-negative patients, with a pooled AOR of 2.15 (95% confidence interval (CI) 1.47–3.17, I2 = 38%). Similarly, contacts of patients with the cavitary disease were around twice as likely to be infected as contacts of patients without cavitation (pooled AOR 1.9, 95% CI 1.26–2.84, I2 = 63%). In contrast, HIV seropositive patients were associated with few contact infections than HIV seronegative patients (AOR 0.45, 95% CI 0.26–0.80, I2 = 52%). In conclusion, behavioural and clinical characteristics of TB patients can be used to identify highly infectious patients for targeted interventions.

First Admission

Objective: This study examines the impact of the transition process on the mortality of elderly individuals following their first admission to nursing home from the community at 1, 3, and 6 months postadmission, and causes and risk factors for death. Method: A systematic review of relevant studies published between 2000 and 2015 was conducted using key search terms: first admission, death, and nursing homes. Results: Eleven cohort studies met the inclusion criteria. Mortality within the first 6 month postadmission varied from 0% to 34% (median = 20.2). Causes of deaths were not reported. Heightened mortality was not wholly explained by intrinsic resident factors. Only two studies investigated the influence of facility factors, and found an increased risk in facilities with high antipsychotics use. Discussion: Mortality in the immediate period following admission may not simply be due to an individual’s health status. Transition processes and facility characteristics are potentially independent and modifiable risk factors.

The Impact

IntroductionHypertensive disorders of pregnancy (HDPs), that is chronic hypertension, gestational hypertension, pre-eclampsia (de novo or superimposed on chronic hypertension) and white coat hypertension, affect approximately 5%–15% of pregnancies. HDP exposure has been linked to an increased risk of autism spectrum disorder, attention deficit/hyperactivity disorder and other neurodevelopmental disorders in children. However, findings are inconsistent, and a clear consensus on the impact of HDPs on the risk of neurodevelopmental disorders is needed. Therefore, we aim to synthesise the published literature on the relationship between HDPs and the risk of neurodevelopmental disorders in the form of a systematic review and meta-analysis.Methods and analysisWe will include cohort, case–control and cross-sectional studies in which diagnosis of an HDP was reported, and neurodevelopmental disorders were the outcome of interest based on a preprepared protocol. A systematic search of PubMed, CINAHL, Embase, PsycINFO and Web of Science will be conducted in accordance with a detailed search strategy. Two authors will independently review the titles and abstracts of all studies, perform data extraction using a standardised data collection form and assess study quality using a bias classification tool. Meta-analyses will be performed to calculate overall pooled estimates using the generic inverse variance method. This systematic review will be reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses.Ethics and disseminationThis proposed systematic review and meta-analysis is based on published data, therefore, does not require ethics approval. Findings will be presented at scientific conferences and disseminated through publication in a peer-reviewed journal.RegistrationCRD42017068258.
