e22171 Background: Previously, TP53 codon 72 polymorphisms have been implicated as risk factors for various cancers. Several studies have conducted on the association of TP53 codon 72 polymorphisms with susceptibility to breast carcinoma and have yielded inconclusive results. The aim of the present study was to assess possible associations of breast cancer risk with TP53 codon 72 polymorphisms. Methods: We conducted a search in the Medline, EMBASE, OVID, Sciencedirect, and Chinese National Knowledge Infrastructure (CNKI) without a language limitation, covering all papers published up to Dec 2008. The associated literature was acquired through deliberate searching and selected based on the established inclusion criteria for publications. Results: Consequently, fifteen studies, including 3436 cases and 4394 controls, met the included criteria and thus were selected. Ultimately, the relevant data were extracted and further analyzed using systematic meta- analyses. The results showed that individuals carrying homozygote Arg/Arg genotype have a significant increased risk of breast cancer compared with those carrying Pro/Pro genotype (OR: 1.58, 95%CI:1.10–2.28). For Arg allele, no evidence indicated that individuals with Arg/Arg genotype have an increased risk of breast cancer compared with those with a combined Pro genotype (Arg/Pro+Pro/Pro) (OR: 1.68, 95%CI:1.24–2.29). For Pro allele, individuals with homozygote Pro/Pro genotype have a marked decreased susceptibility to breast cancer relative to those with a combined Arg genotype (Arg/Pro+Arg/Arg) (OR: 0.84, 95%CI:0.73–0.98). Conclusions: The results of the present study suggest that TP53 codon 72 polymorphisms might be a risk factor for breast cancer. Homozygote Arg allele genotype could significantly increase susceptibility to breast cancer, while Pro/Pro allele markedly decreases breast risk. No significant financial relationships to disclose.

Background. MicroRNA-423 (miR-423) rs6505162 polymorphism is found to be associated with breast cancer (BC) risk. However, the results were inconsistent. This study meta-analyzed the literature on possible association between rs6505162 polymorphism and BC risk. Methods. PubMed, Embase, Google Scholar, and the Chinese National Knowledge Infrastructure (CNKI) databases were systematically searched to identify relevant studies. Meta-analyses were performed to examine the association between rs6505162 polymorphism and BC. Results. None of the five genetic models suggested a significant association between rs6505162 polymorphism and BC risk: allelic model, OR 1.02, 95% CI 0.18–1.28, P = 0.85 ; recessive model, OR 0.99, 95% CI 0.72–1.38, P = 0.97 ; dominant model, OR 0.93, 95% CI 0.72–1.21, P = 0.60 ; homozygous model, OR 1.04, 95% CI 0.66–1.65, P = 0.87 ; and heterozygous model, OR 1.07, 95% CI 0.90–1.28, P = 0.45 . Similar results were obtained in subgroup analyses of Asian, Chinese, and Caucasian patients. Conclusion. The available evidence suggests no significant association between rs6505162 polymorphism and BC risk. These conclusions should be verified in large, well-designed studies.

Aims: The objective of this review was to examine the relationship between osteoarthritis (OA) and mobility-related comorbidities, specifically diabetes mellitus (DM) and cardiovascular disease (CVD). It also investigated the relationship between OA and mortality. Methods: An overview of meta-analyses was conducted by performing two targeted searches from inception to June 2020. The association between OA and (i) DM or CVD ( via PubMed and Embase); and (ii) mortality ( via PubMed) was investigated. Meta-analyses were selected if they included studies that examined adults with OA at any site and reported associations between OA and DM, CVD, or mortality. Evidence was synthesized qualitatively. Results: Six meta-analyses met inclusion criteria. One meta-analysis of 20 studies demonstrated a statistically significant association between OA and DM, with pooled odds ratio of 1.41 (95% confidence interval: 1.21, 1.65; n = 1,040,175 patients). One meta-analysis of 15 studies demonstrated significantly increased risk of CVD among OA patients, with a pooled risk ratio of 1.24 (1.12, 1.37, n = 358,944 patients). Stratified by type of CVD, OA was shown to be associated with increased heart failure (HF) and ischemic heart disease (IHD) and reduced transient ischemic attack (TIA). There was no association reported for stroke or myocardial infarction (MI). Three meta-analyses did not find a significant association between OA (any site) and all-cause mortality. However, OA was found to be significantly associated with cardiovascular-related death across two meta-analyses. Conclusion: The identified meta-analyses reported significantly increased risk of both DM and CVD (particularly, HF and IHD) among OA patients. It was not possible to confirm consistent directional or causal relationships. OA was found to be associated with increased mortality, but mostly in relation to CVD-related mortality, suggesting that further study is warranted in this area.

Abstract Background Echinococcosis is a severe zoonotic disease that imposes a substantial burden on human life. Numerous studies on echinococcosis have involved a variety of risk factors, and it is difficult to evaluate the key risk factors. The objectives of this meta-analysis are to summarize available data on the prevalence of human echinococcosis and identify the key risk factors for echinococcosis. Methods Relevant studies were comprehensively searched in the PubMed, EMBASE, Web of Science, Cochrane, Chinese National Knowledge Infrastructure (CNKI), Chongqing VIP Information (VIP), Wanfang and SinoMed databases from database inception until August 22, 2020. A random-effects model was used to estimate the pooled odds ratio (OR) and 95% confidence interval (CI) by integrating the OR values of each risk factor. The I2 and Q statistics were calculated to evaluate the heterogeneity, and potential sources of heterogeneity were identified using sensitivity analysis and subgroup analysis. Publication bias was estimated by funnel plots and Egger’s test. Results A total of 1026 studies were identified through the database search, of which 26 were eligible for this meta-analysis. In total, 23 and 9 of the 26 studies were cystic echinococcosis (CE) and alveolar echinococcosis (AE) studies, respectively (6 papers included both AE and CE). The pooled prevalence of echinococcosis was 5.52% (95% CI: 5.47%-5.58%). Ethnicity (OR = 2.93, 95% CI: 1.81–4.75; I2 = 0), being a herder (OR = 2.66, 95%CI95% CI: 2.25–3.14; I2 = 8%), not washing hands before meals (OR = 2.40, 95% CI: 1.34–4.28; I2 = 82.8%) and being female (OR = 1.45, 95% CI: 1.26–1.66; I2 = 33.9%) were risk factors for AE. The top five risk factors for CE were ethnicity (OR = 3.18, 95% CI: 1.55–6.52; I2 = 79.2%), nomadism (OR = 2.71, 95% CI: 1.65–4.47; I2 = 55.8%), drinking nonboiled water (OR = 2.47, 95% CI: 1.36–4.47; I2 = 85.7), feeding viscera to dogs (OR = 2.35, 95% CI: 1.89–2.91; I2 = 21.5%), and being a herder (OR = 2.19, 95% CI: 1.67–2.86; I2 = 85.1%). The study design-specific subgroup analysis showed that the heterogeneity of CE risk factors decreased to varying degrees. Conclusions Specific characteristics (i.e., ethnicity and herder status) and behaviors (i.e., not washing hands before meals and feeding viscera to dogs ) are possible risk factors for echinococcosis. This study provided remarkable insight for future prevention and control of echinococcosis.

Cryptosporidium is a well-known cause of diarrhoea in humans. Little is known about risk factors associated with endemic cryptosporidiosis, which constitutes the majority of cases. We carried out meta-analyses to verify if drinking water is also associated with endemic infection and to assess the magnitude of the associations. The global meta-analysis suggests that there is an increased risk of Cryptosporidium infection among unsafe water users (OR 1.40 [1.15, 1.72]). Studies were stratified, according to the exposure to different sources of safe drinking water, due to the heterogeneity presented. The consumption of non-well and unboiled water was associated with an increased chance of endemic cryptosporidiosis, though only the latter was significant (OR 1.45 [0.95, 2.20]; OR 1.61 [1.09, 2.38]). Drinking non-bottled water did not present a risk factor associated with endemic cryptosporidiosis (OR 0.87 [0.72, 1.05]). These meta-analyses present results that could be useful to clarify the epidemiology of Cryptosporidium. We recommend that other risk factors could also be studied by this approach.

BackgroundGastroschisis is strongly associated with young maternal age. This association suggests the need for further investigations on non-genetic risk factors. Identifying these risk factors is a public health priority in order to develop prevention strategies aimed at reducing the prevalence and health consequences in offspring.ObjectiveTo systematically assess and quantitatively synthesise the available epidemiological studies to evaluate the association between non-genetic risk factors and gastroschisis.MethodsLiterature from PubMed, EMBASE and Scopus was searched for the period 1990–2018. Epidemiological studies reporting risk estimates between lifestyle and sociodemographic risk factors and gastroschisis were included. Two pairs of reviewers independently extracted information on study characteristics following Preferred Reporting Items for Systematic Reviews and Meta-Analyses and MOOSE (Meta-analysis Of Oservational Studies in Epidemiology) guidelines. Relative risk (RR) estimates were calculated across the studies and meta-analysis was performed using random-effects model.ResultsWe identified 58 studies. Meta-analyses were conducted on 29 studies. Maternal smoking (RR 1.56, 95% CI 1.40 to 1.74), illicit drug use (RR 2.14, 95% CI 1.48 to 3.07) and alcohol consumption (RR 1.40, 95% CI 1.13 to 1.70) were associated with an increased risk of gastroschisis. A decreased risk among black mothers compared with non-Hispanic white mothers (RR 0.49, 95% CI 0.38 to 0.63) was found. For Hispanic mothers no association was observed.ConclusionsExposure to smoking, illicit drugs and alcohol during pregnancy is associated with an increased risk of gastroschisis. A significantly decreased risk for black mothers was observed. Further epidemiological studies to assess the potential role of other environmental factors are strongly recommended.PROSPERO registration numberCRD42018104284.

Abstract Plasma levels of haemostatic proteins involved in coagulation and fibrinolysis may represent an important intermediate phenotype for cardiovascular diseases (because increased levels of these proteins have been associated with an increased/reduced risk of thrombosis). However, investigation in arterial diseases of gain-of-function polymorphisms of genes encoding coagulation factor V (F5 G1691A) and prothrombin (F2 G20210A), established risk factors for venous thrombosis, have generally indicated weak or no associations in a number of conflicting and inconclusive reports [Ye et al., Lancet2006;367:651–8]. These negative results might be due to the sample size, too small to reliably assess relatively small genetic effects. Recently, a meta-analysis of 4,944 patients and 7,090 controls on the association of the F2 G20210A and ischemic heart disease [Burzotta et al, Heart2004;90:82–6], and a meta-analysis of 66,155 cases and 91,307 controls on the association of haemostatic genetic variants and coronary artery disease (CAD) [Ye et al, Lancet2006;367:651–8], found that either F2 G20210A and F5 G1691A polymorphisms were associated with a moderately increased risk of CAD. Results from these meta-analyses, large but based respectively upon 19 and 100 different studies all of rather small size, should be taken cautiously. Considering that genetic factors play a particularly important role in CAD occurring in the young, with usually less coronary atherosclerosis and a high prevalence of normal or near-normal coronary angiograms, we chose to replicate the meta-analysis results by investigating an adequately large population of 1,864 Italian patients who developed myocardial infarction (MI) before the age of 45 yrs (1,655 men and 209 women) and 1,864 age- and sex-matched controls. Genotyping was performed by Sequenom MassARRAY platform. Statistical analysis was performed fitting a conditional logistic model with STATA 9.2 software. Our results showed that the minor A allele of F5 G1691A (2.6% frequency in cases and 1.7% in controls) was associated with a moderately increased risk of MI (OR:1.59; 95% CI:1.14–2.20; P=0.006). The association remained statistically significant after adjustment for traditional risk factors, including diabetes, smoking, hypertension, and hypercholesterolemia (OR:1.81; 95% CI:1.14–2.87; P=0.012). The minor A allele of F2 G20210A (2.4% frequency in cases and 1.9% in controls) was not associated with the risk of MI (OR:1.27; 95% CI:0.93–1.74; P=0.133), even after adjustment (OR:1.19; 95% CI:0.77–1.85; P=0.429). In conclusion, results of the previous meta-analyses are replicated only partially in this cohort of young MI patients, the largest investigated so far, as only the gain-of-function variant F5 G1691A (but not F2 G20210A) was associated with an increased risk of MI. Our results suggest that anticoagulant drugs might be considered for secondary prophylaxis of MI in patients with the F5 gene variant, who carry a procoagulant phenotype.

ObjectiveTo synthesise, quantify and compare risks for incident myocardial infarction (MI) across five major types of arthritis in population-based studies.MethodsA systematic search was performed in MEDLINE, EMBASE and CINAHL databases with additional manual/hand searches for population-based cohort or case-control studies published in English of French between January 1980 and January 2015 with a measure of effect and variance for associations between incident MI and five major types of arthritis: rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), gout or osteoarthritis (OA), adjusted for at least age and sex. All search screening, data abstraction quality appraisals were performed independently by two reviewers. Where appropriate, random-effects meta-analysis was used to pool results from studies with a minimum of 10 events.ResultsWe identified a total of 4, 285 articles; 27 met review criteria and 25 criteria for meta-analyses. In studies adjusting for age and sex, MI risk was significantly increased in RA (pooled relative risk (RR): 1.69, 95% CI 1.50 to 1.90), gout (pooled RR: 1.47, 95% CI 1.24 to 1.73), PsA (pooled RR: 1.41, 95% CI 1.17 to 1.69), OA (pooled RR: 1.31, 95% CI 1.01 to 1.71) and tended towards increased risk in AS (pooled RR: 1.24, 95% CI 0.93 to 1.65). Traditional risk factors were more prevalent in all types of arthritis. MI risk was attenuated for each type of arthritis in studies adjusting for traditional risk factors and remained significantly increased in RA, PsA and gout.ConclusionsMI risk was consistently increased in multiple types of arthritis in population-based studies, and was partially explained by a higher prevalence of traditional risk factors in all types of arthritis. Findings support more integrated cardiovascular (CV) prevention strategies for arthritis populations that target both reducing inflammation and enhancing management of traditional CV risk factors.

Background: Breast cancer is the second most common cancer among women in India and accounts for 7% of global burden of breast cancer and one-fifth of all cancers among women in India. The risk factors are related to lifestyle, early menarche, nulli parity, prolonged use of oral contraceptive pills, hormone replacement therapy, not breast‑feeding, alcohol, obesity, lack of exercise, and induced abortion. A woman who attains menopause after fifty five years of age has an increased risk of ovarian, breast, and uterine cancers. The risk is greater if a woman also began menstruating before twelve years of age. A longer exposure to estrogen increases a woman’s risk of breast cancers.Methods: This is a prospective observational study, conducted in the department of surgery, between December 2013 and June 2015(2 years). Patients diagnosed as breast carcinoma and admitted in surgical wards were included, Data pertaining to demography, clinical and pathological tumor profile, and treatment details were collected prospectively for each patient based on patient interviews and medical records. To analyse the Prevalence of breast cancer, clinical presentation, risk factors, diagnostic methods, treatment protocols, difference between pre and post‑menopausal breast cancer women regarding risk factors, assess the impact of treatment given and women’s knowledge about breast cancer.Results: A total number of 25 cases of breast carcinoma based on detailed history, clinical examination, Trucut biopsy, ultrasonography breast and axilla, ultrasound abdomen, mammogram and chest x-ray were analysed. All of them received three cycles of anterior chemotherapy consisting of 5- Fluorouracil 500 mg/m2,Adriamycin 50 mg/m2 Cyclophosphamide 80 mg/m2 (FAC regimen) administered intravenously followed by modified radical mastectomy. There were no recurrences seen on follow up till date.Conclusions: Late stage at presentation of breast cancer is a challenge to the health care providers. Cancer awareness programmes, multidisciplinary approach and evidence‑based strategies for early detection and effective management of the disease can go a long way in prevention.

Abstract Study question Do high birth weight or large for gestational age (LGS) increase the risk of serious disease later in life? Summary answer High birth weight and/or LGA were associated with elevated risks for certain child malignancies, breast cancer, psychiatric disorders, childhood hypertension and diabetes type 1. What is known already Previous studies have shown that children born after frozen embryo transfer (FET) have an increased risk of being born LGA or having a high birth weight. In recent years the practice of FET in Assisted Reproductive Technology (ART) has increased rapidly. The perinatal risks of being born LGA or with a high birth weight are well studied, however less is known about the impact on long-term health and morbidity. Study design, size, duration Pubmed, Scopus and Web of Science were searched until December 2020. 11 748 abstracts were screened, 172 publications were selected for systematic review and 63 for meta-analyses. The methodological quality in terms of risk of bias was assessed by pairs of reviewers. Robin-I (www.methods.cochrane.org) was used for assessing risk of bias in original articles. For systematic reviews AMSTAR was used. For certainty of evidence the GRADE system was used. Participants/materials, setting, methods Exposures were LGA and high birth weight. Long-term morbidity outcomes were cancer, metabolic disease, cardiovascular disease and psychiatric disorders. Cancer was focused on breast cancer, child malignancies in the central nervous system (CNS), hematological malignancies and Wilm´s tumor. Metabolic diseases included diabetes type 1 and type 2. Cardiovascular diseases were focused on hypertension and other cardiovascular disorders and psychiatric disorders on schizophrenia/psychosis and cognitive disorders. Main results and the role of chance Pooled Adjusted Odds Ratios (AOR) for outcome variables were compared for birth weights >4000 or > 4500 g versus < 4000 g. For cancer, meta-analyses showed AOR of 1.24 (95% 1.11-1.39) for development of breast cancer, AOR of 1.15 (95% CI 1.05-1.27) for development of CNS tumors, AOR of 1.29 (95% CI 1.20-1.39) for childhood leukemia and AOR 1.68 (95% CI 1.38-2.06 ) for Wilm´s tumor. For metabolic disease a meta-analysis showed AOR of 1.15 (95%CI 1.05-1.26) for the association between high birth weight and type 1 diabetes. For psychiatric diseases an association was found between high birth weight and/or LGA and schizophrenia and depression. For cardiovascular disease, an association was found between high birth weight and hypertension in childhood with an inverse association in adulthood. No difference in the risk of coronary heart disease in adults born with high birth weight compared to normal birth Limitations, reasons for caution The main limitation is that all data are based on observational studies with their inborn risk of selection bias. Our conclusions are however, mainly based on meta-analyses and/or studies with low risk of bias. Wider implications of the findings Even though high birth weight and LGA are associated with an increased risk of serious diseases, both in childhood and in adulthood, the size of these effects seems modest. However, the identified risk associations should be taken into account in stimulation strategies and when considering fresh or frozen embryo transfer. Trial registration number Not applicable

Objective. Recent studies on the association between uridine diphosphosglucuronosyltransferases (UGTs) 2B17 polymorphism and risk of prostate cancer (PCa) showed inconclusive results. To clarify this possible association, we conducted a meta-analysis of published studies. Methods. We searched the published literature from PubMed, Embase, Google Scholar, and China National Knowledge Infrastructure (CNKI). According to our inclusion criteria, studies that observed the association between UGT2B17 polymorphism and PCa risk were included. The principal outcome measure was the adjusted odds ratio (OR) with 95% confidence interval (CI) for the risk of PCa associated with UGT2B17 polymorphism. Results. A total of 6 studies with 7,029 subjects (3,839 cases and 3,190 controls) were eligible for inclusion in the meta-analysis. Overall, there was a significant association between UGT2B17 polymorphism and increased risk of prostate cancer (, 95% CI 1.14–2.64, ). Similar results were found in the subgroup analyses by ethnicity and types of controls. Conclusion. This meta-analysis demonstrates that UGT2B17 polymorphism is associated with prostate cancer susceptibility, and it contributes to the increased risk of prostate cancer.
