ABSTRACT Objectives To evaluates the role of diet in determining knee osteoarthritis risk. Methods Literature search was conducted in Ovid, PubMed, Science Direct, and Springer. To estimate knee osteoarthritis risk with high use of vegetarian, prudent, and omnivorous diets, dairy products, vitamin C/E, and carotenoids, the odds ratios (ORs) or relative risks (RRs) reported by included studies were pooled. Results Fifteen studies (97,157 individuals) were included. High use of vegetarian diet {OR 0.71 [95% confidence interval (CI): 0.45, 0.97]}, prudent diet [OR 0.87 (95% CI: 0.76, 0.98)/RR 0.89 (95% CI: 0.82, 0.97)], and dairy [OR 0.66 (95% CI: –0.08, 1.39)/RR 0.58 (95% CI: 0.41, 0.75)] were associated with lower risk of knee osteoarthritis but risk was relatively higher with high use of omnivorous diet [OR 1.13 (95% CI: 0.95, 1.30)/RR 1.06 (95% CI: 0.84, 1.29) and 1.05 (0.78, 1.33)]. High intake of vitamin C [OR 0.92 (0.29, 1.56)] or E [OR 0.93 (0.64, 1.21)] did not reduce knee osteoarthritis risk, but high use of carotenoids was associated with the lower risk [OR 0.66 (0.37, 0.96)]. Conclusions Knee osteoarthritis risk is low with high use of vegetarian diet, prudent diet, and dairy, but cannt be reduced by high intakes of vitamin C/E.

AbstractObjectiveThe present review aimed to quantify the association of dietary intake and circulating concentration of major dietary antioxidants with risk of total CVD mortality.DesignSystematic review and meta-analysis.SettingSystematic search in PubMed and Scopus, up to October 2017.ParticipantsProspective observational studies reporting risk estimates of CVD mortality across three or more categories of dietary intakes and/or circulating concentrations of vitamin C, vitamin E and β-carotene were included. A random-effects meta-analysis was conducted.ResultsA total of fifteen prospective cohort studies and three prospective evaluations within interventional studies (320 548 participants and 16 974 cases) were analysed. The relative risks of CVD mortality for the highest v. the lowest category of antioxidant intakes were as follows: vitamin C, 0·79 (95 % CI 0·68, 0·89; I2=46 %, n 10); vitamin E, 0·91 (95 % CI 0·79, 1·03; I2=51 %, n 8); β-carotene, 0·89 (95 % CI 0·73, 1·05; I2=34 %, n 4). The relative risks for circulating concentrations were: vitamin C, 0·60 (95 % CI 0·42, 0·78; I2=65 %, n 6); α-tocopherol, 0·82 (95 % CI 0·76, 0·88; I2=0 %, n 5); β-carotene, 0·68 (95 % CI 0·52, 0·83; I2=50 %, n 6). Dose–response meta-analyses demonstrated that the circulating biomarkers of antioxidants were more strongly associated with risk of CVD mortality than dietary intakes.ConclusionsThe present meta-analysis demonstrates that higher vitamin C intake and higher circulating concentrations of vitamin C, vitamin E and β-carotene are associated with a lower risk of CVD mortality.

Cvd Mortality

Background. Legume consumption is suggested to have protective effects against cardiovascular disease (CVD) mortality in the general population, but the results have been equivocal. We conducted a meta-analysis of prospective cohort studies to assess the association between legume consumption and risk of CVD mortality and all-cause mortality. Methods and Results. Medline (via Ovid) and EMBASE (via Ovid) databases were searched through April 2017 to identify eligible studies. The two authors independently extracted the data and the adjusted relative risks (RRs) and 95% confidence intervals (CIs) were pooled by using a random-effects model. A total of 6 studies were identified, including the sizes of participants ranging from 23,601 to 59,485 with a sum of 21,8997. Comparing the highest category with the lowest, the pooled RR (95% CI) was 0.96 (0.86–1.06) for CVD mortality and 0.93 (0.87–0.99) for all-cause mortality. Conclusions. Results from the current study show that high legume intakes are associated with lower risk of all-cause mortality. In consideration of the small number of studies, the evidence for assessing relationship between legumes intake and risk of all-cause mortality remains inclusive and warrants further study in the future. Further, consuming legumes does not increase the risk of CVD mortality.

Maternal diet during pregnancy might influence the development of childhood allergic disorders. The aim of the present study was to evaluate the impact of Mediterranean diet (MD) adherence during pregnancy on wheeze and eczema in the first year of life in two population-based mother–child cohorts in Spain and Greece. We studied 1771 mother–newborn pairs from the Spanish multi-centre ‘INMA’ (INfancia y Medio Ambiente) study (Gipuzkoa, Sabadell and Valencia) and 745 pairs from the ‘RHEA’ study in Crete, Greece. The symptoms of wheeze and eczema were based on the criteria of the International Study of Asthma and Allergies in Childhood. Maternal diet during pregnancy was assessed by FFQ and MD adherence was evaluated through an a priori score. Multivariate log-binomial regression models were used to adjust for several confounders in each cohort and summary estimates were obtained by a meta-analysis. MD adherence was not associated with the risk of wheeze and eczema in any cohort, and similar results were identified in the meta-analysis approach. High meat intake (relative risk (RR) 1·22, 95 % CI 1·00, 1·49) and ‘processed’ meat intake (RR 1·18, 95 % CI 1·02, 1·37) during pregnancy were associated with an increased risk of wheeze in the first year of life, while a high intake of dairy products was significantly associated with a decreased risk of infantile wheeze (RR 0·83, 95 % CI 0·72, 0·96). The results of the present study show that high meat intake during pregnancy may increase the risk of wheeze in the first year of life, while a high intake of dairy products may decrease it.

Abstract The present meta-analysis was conducted to explore the role of milk and dairy products consumption on oral or oropharyngeal cancer risk. PubMed, Embase and Chinese Wanfang databases were investigated until 30 June 2019. The overall and subgroup associations were pooled with odds ratios (ORs) and 95% confidence intervals (CIs). As a result, the present study involving 4635 cases and 50777 participants from 12 publications suggested that an inverse association was found between milk and dairy products consumption and oral or oropharyngeal cancer risk (OR = 0.74, 95% CI = 0.59–0.92; I2 = 65.9%, Pfor heterogeneity=0.001). Four studies reported milk consumption on oral cancer risk, but no significant association was found (OR = 0.91, 95% CI = 0.61–1.37). Six studies about milk consumption and oropharyngeal cancer risk found that there was a positive association between them (OR = 0.63, 95% CI = 0.44–0.90). In conclusion, findings from our meta-analysis indicated that milk and dairy products consumption may be associated with decreased risk of oral or oropharyngeal cancer.

Introduction: Recent research has focused on the role of persistent ascending bacterial infections and sexually transmitted infections (STI) as a factor associated to endometriosis. Indeed, some studies investigated the possible role of HPV in endometriosis, but this topic remains inconclusive. Objective:The present study aims to meta-analyze research that assessed the presence of HPV infection in patients with endometriosis. Methods: MEDLINE, Embase, Scopus, LILACS, Cochrane Library, and OpenGrey were searched until February 10th, 2020. Search terms included “endometriosis” and “HPV” without language restrictions. The combined relative risks and 95% confidence interval (95%CI) were calculated, and heterogeneity was assessed with I-square (I2 ). Results: Meta-analysis with low heterogeneity found a relative risk of twice as much in women exposed to HPV in relation to the unexposed control. Conclusion: Results indicate that HPV could be a risk factor for developing endometriosis.

Dietary Indices

Background: The association between plant-based diets and cardiovascular disease (CVD) remains poorly characterized. Given that diet represents an important and a modifiable risk factor, this study aimed to assess (1) the relationships between the impact of adherence to plant-based diets on cardiovascular mortality, incident CVD, and stroke; (2) if associations differed by adherence to healthful and less healthful plant-based diets.Methods and Findings: MEDLINE and EMBASE databases were searched up to May 2021. Studies assessing CVD outcomes with relation to plant-based dietary patterns or according to plant-based dietary indices (PDI) were included. A meta-analysis of hazard ratios (HR) was conducted using DerSimonian and Laird random effects model. Thirteen studies involving 410,085 participants were included. Greater adherence to an overall plant-based dietary pattern was significantly associated with a lower risk of cardiovascular mortality (pooled HR: 0.92, 95% CI: 0.86–0.99 p = 0.0193, I2 = 88.5%, N = 124,501) and a lower risk of CVD incidence (pooled HR: 0.90, 95% CI: 0.82–0.98, p = 0.0173, I2 = 87.2%, N = 323,854). Among the studies that used PDI, unhealthful plant-based diets were associated with increased risk of cardiovascular mortality (pooled HR: 1.05, 95% CI: 1.01–1.09, p = 0.0123, I2 = 0.00%, N = 18,966), but not CVD incidence. Conversely, healthful plant-based diets were associated with decreased CVD incidence (pooled HR: 0.87, 95% CI: 0.80–0.95, p = 0.0011, I2 = 57.5%, N = 71,301), but not mortality. Vegetarians also had significantly lower CVD incidence (HR: 0.81, 95% CI: 0.72–0.91, p = 0.0004, I2 = 22.2%, N = 16,254), but similar CVD mortality or stroke risk when compared to the meat-eaters.Conclusion: To date, this comprehensive study examines the effects of a plant-based diet on major clinical endpoints using more holistic PDIs. These findings highlight the favorable role of healthful plant-based foods in reducing cardiovascular mortality and CVD.

OBJECTIVE: To examine the relationship between gastroesophageal reflux (GER) and COPD exacerbations. METHODS: We conducted a systematic search of various electronic databases for articles published up through December of 2012. Studies considered eligible for inclusion were those dealing with COPD, COPD exacerbations, and GER; comparing at least two groups (COPD vs. controls or GER vs. controls); and describing relative risks (RRs) and prevalence ratios-or ORs and their respective 95% CIs (or presenting enough data to allow further calculations) for the association between GER and COPD-as well as exacerbation rates. Using a standardized form, we extracted data related to the study design; criteria for GER diagnosis; age, gender, and number of participants; randomization method; severity scores; methods of evaluating GER symptoms; criteria for defining exacerbations; exacerbation rates (hospitalizations, ER visits, unscheduled clinic visits, prednisone use, and antibiotic use); GER symptoms in COPD group vs. controls; mean number of COPD exacerbations (with symptoms vs. without symptoms); annual frequency of exacerbations; GER treatment; and severity of airflow obstruction. RESULTS: Overall, GER was clearly identified as a risk factor for COPD exacerbations (RR = 7.57; 95% CI: 3.84-14.94), with an increased mean number of exacerbations per year (mean difference: 0.79; 95% CI: 0.22-1.36). The prevalence of GER was significantly higher in patients with COPD than in those without (RR = 13.06; 95% CI: 3.64-46.87; p < 0.001). CONCLUSIONS: GER is a risk factor for COPD exacerbations. The role of GER in COPD management should be studied in greater detail.

Abstract In this systematic review and dose-response meta-analysis, we aim to assess whether coffee and tea consumption is related to the risk of glioma. We performed a systematic literature search using PubMed, Embase, Scopus, and the EuropePMC up until 1st October 2020. Exposures in this study were coffee and tea consumption. The main outcome of this study was the incidence of glioma. This study compares the association between the exposure of coffee and tea with the incidence of glioma, the results are reported in Relative Risks (RRs). There are 12 unique studies comprising of 1,960,731 participants with 2,987 glioma cases. Higher coffee consumption was associated with a statistically non-significant trend towards lower risk of glioma (RR 0.77 [0.55, 1.03], p=0.11; I2: 75.27%). Meta-regression showed that the association between coffee and glioma was reduced by smoking (p=0.029). Higher tea consumption was associated with the lower risk of glioma (RR 0.84 [0.71, 0.98], p=0.030; I2: 16.42%). Sensitivity analysis by removal of case-control studies showed that higher coffee consumption (RR 0.85 [0.72, 1.00], p=0.046; I2: 0%) and higher tea consumption (RR 0.81 [0.70, 0.93], p=0.004; I2: 0%, Pnon-linearity=0.140) were associated with lower risk of glioma. Dose-response meta-analysis showed that every 1 cup of coffee per day decreases the risk of glioma by 3% (RR 0.97 [0.94, 0.99], p=0.016, Pnon-linearity=0.054) and every 1 cup of tea per day decreases the risk of glioma by 3% (RR 0.97 [0.94, 1.00], p=0.048). This meta-analysis showed apparent association between coffee and tea intake and risk of glioma.

BACKGROUND: Although widely studied, the role of HPV in the genesis of breast carcinomas remains elusive due to the diversity of results across studies, possibly caused by the wide methodological heterogeneity, some of them with inadequate methods. OBJECTIVE: To verify the association between HPV and breast cancer through the meta-analysis of studies that used the best-recognized techniques for viral detection and tissue conservation. METHODS: A systematic review and meta-analysis restricted to studies that detected HPV by PCR in fresh and frozen tissue from breast cancer were conducted to obtain greater homogeneity. PubMed, Scopus, Science Direct, Cochrane Library, and SciELO were searched until December 14, 2019. Search terms included “breast cancer” and “HPV” without language restrictions. Eleven studies were included in the meta-analysis. The pooled relative risks and 95% confidence interval (95% CI) were calculated, and heterogeneity was assessed using the I-squared (I2). RESULTS: The selected studies had very low heterogeneity (2%). There is a 2.15 times higher combined relative risk (95% CI = 1.60-2.89) of detecting HPV in breast cancer than in cancer-free breast controls with a statistically significant p-value (p < 0.0001). CONCLUSION: Our data support the association of DNA-HPV with breast carcinomas. Further studies are needed to find out which breast cancer subtypes this association is most frequent.
