Abstract Background Smoking is a major risk factor for periodontitis and tooth loss. Smoking cessation has a positive impact in periodontal treatment. However, so far, no systematic review has evaluated the effect of smoking cessation on tooth loss. Therefore, this review aimed to evaluate if smoking cessation reduces the risk of tooth loss. Methods Observational (cross-sectional and longitudinal) studies that investigated the association between smoking cessation and tooth loss were included. MEDLINE, EMBASE and LILACS databases were searched for articles published up to November 2018. Pooled results for subgroups of current and former smokers were compared in meta-analysis. Meta-regression was used to test the influence of smoking status on estimates and explore the heterogeneity. Results Of 230 potentially relevant publications, 21 studies were included in the qualitative review and 12 in the quantitative analysis. Meta-analysis of cross-sectional studies did not show any differences between former and current smokers in the chance of losing 1 or more teeth (OR = 1.00; 95% CI = 0.80 to 1.24, I2 = 80%), losing more than 8 teeth (OR = 1.02; 95% CI = 0.78 to 1.32, I2 = 0%) or being edentulous (OR = 1.37; 95% CI = 0.94 to 1.99, I2 = 98%). Meta-analysis from longitudinal studies showed that, when compared to never smokers, former smokers presented no increased risk of tooth loss (RR = 1.15; 95% CI = 0.98 to 1.35, I2 = 76%), while current smokers presented an increased risk of tooth loss (RR = 2.60; 95% CI = 2.29 to 2.96, I2 = 61%). Meta-regression showed that, among former smokers, the time of cessation was the variable that better explained heterogeneity (approximately 60%). Conclusions Risk for tooth loss in former smokers is comparable to that of never smokers. Moreover, former smokers have a reduced risk of tooth loss, when compared to current smokers.

Background We conducted a systematic review and meta-analysis to clarify the association between smoking and the risk of developing heart failure. Methods PubMed and Embase databases were searched up to 24 July 2018. Prospective studies were included if they reported adjusted relative risk (RR) estimates and 95% confidence intervals (CIs) of heart failure associated with smoking. Summary RRs and 95% CIs were estimated using a random effects model. Results Twenty-six studies were included. The summary RR was 1.75 (95% CI: 1.54–1.99, I2 = 81%, n = 10) for current smokers, 1.16 (95% CI: 1.08–1.24, I2 = 51%, n = 9) for former smokers, and 1.44 (1.34–1.55, I2 = 83%, n = 10) for ever smokers compared with never smokers. The summary RR was 1.41 (95% CI: 1.01–1.96, I2 = 82%, n = 2) per 10 cigarettes per day, 1.11 (95% CI: 1.04–1.18, I2 = 70%, n = 3) and 1.08 (95% CI: 1.02–1.14, I2 = 34%, n = 2) per 10 pack-years among ever smokers and former smokers, respectively, and 0.79 (95% CI: 0.63–1.00, I2 = 96%, n = 2) per 10 years since quitting smoking. The association between smoking cessation and heart failure reached significance at 15 years of smoking cessation, and at 30 years the summary RR was 0.72 (95% CI: 0.57–0.90), only slightly higher than the summary RR for never smokers (0.64 (95% CI: 0.57–0.72)) when compared with current smokers. Conclusion Smoking is associated with increased risk of heart failure, but the risk decreases with increasing duration since smoking cessation. Any further studies should investigate the association between number of cigarettes per day, duration, pack-years and time since quitting smoking and risk of heart failure.

Abstract Background Age-related sensory loss and frailty are common conditions among older adults, but epidemiologic research on their possible links has been inconclusive. Clarifying this relationship is important because sensory loss may be a clinically relevant risk factor for frailty. Methods In this systematic review and meta-analysis, we searched 3 databases for observational studies investigating 4 sensory impairments—vision (VI), hearing (HI), smell (SI), and taste (TI)—and their relationships with frailty. We meta-analyzed the cross-sectional associations of VI/HI each with pre-frailty and frailty, investigated sources of heterogeneity using meta-regression and subgroup analyses, and assessed publication bias using Egger’s test. Results We included 17 cross-sectional and 7 longitudinal studies in our review (N = 34,085) from 766 records. Our cross-sectional meta-analyses found that HI and VI were, respectively, associated with 1.5- to 2-fold greater odds of pre-frailty and 2.5- to 3-fold greater odds of frailty. Our results remained largely unchanged after subgroup analyses and meta-regression, though the association between HI and pre-frailty was no longer significant in 2 subgroups which lacked sufficient studies. We did not detect publication bias. Longitudinal studies largely found positive associations between VI/HI and frailty progression from baseline robustness, though they were inconclusive about frailty progression from baseline pre-frailty. Sparse literature and heterogenous methods precluded meta-analyses and conclusions on the SI/TI–frailty relationships. Conclusions Our meta-analyses demonstrate significant cross-sectional associations between VI/HI with pre-frailty and frailty. Our review also highlights knowledge gaps on the directionality and modifiability of these relationships and the impact of SI/TI and multiple sensory impairments on frailty.

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.

Abstract Understanding association between tooth loss and hypertension is important for improving cardiovascular health. We searched for publications that were published between July 2011 and June 2021 using three electronic databases (PubMed, EMBASE, and Scopus) and conducted a systematic review and meta-analysis on the association between tooth loss and hypertension. Quality assessments were performed using the Critical Appraisal Skills Program guideline, Newcastle–Ottawa Scale and the GRADE approach. Twenty studies (17 cross-sectional studies, and 3 cohort studies) met the inclusion criteria for this review. Most cross-sectional studies showed that subjects with more tooth loss exhibited a greater proportion of hypertension and higher systolic blood pressure than those with less tooth loss. Meta-analyses revealed a statistically significant association between tooth loss and hypertension. The pooled ORFs of hypertension for having tooth loss with no tooth loss and for edentulous with dentate were 2.22 (95% CI 2.00-2.45) and 4.94 (95% CI: 4.04–6.05), respectively. In cohort studies, subjects with more tooth loss had a greater incidence of hypertension than those with less tooth loss during the follow-up period. The present systematic review and meta-analysis suggested that tooth loss is associated with an increased risk of hypertension and higher systolic blood pressure.

Abstract Context: People with CHD are at increased risk for executive functioning deficits. Meta-analyses of these measures in CHD patients compared to healthy controls have not been reported. Objective: To examine differences in executive functions in individuals with CHD compared to healthy controls. Data sources: We performed a systematic review of publications from 1 January, 1986 to 15 June, 2020 indexed in PubMed, CINAHL, EMBASE, PsycInfo, Web of Science, and the Cochrane Library. Study selection: Inclusion criteria were (1) studies containing at least one executive function measure; (2) participants were over the age of three. Data extraction: Data extraction and quality assessment were performed independently by two authors. We used a shifting unit-of-analysis approach and pooled data using a random effects model. Results: The search yielded 61,217 results. Twenty-eight studies met criteria. A total of 7789 people with CHD were compared with 8187 healthy controls. We found the following standardised mean differences: −0.628 (−0.726, −0.531) for cognitive flexibility and set shifting, −0.469 (−0.606, −0.333) for inhibition, −0.369 (−0.466, −0.273) for working memory, −0.334 (−0.546, −0.121) for planning/problem solving, −0.361 (−0.576, −0.147) for summary measures, and −0.444 (−0.614, −0.274) for reporter-based measures (p < 0.001). Limitations: Our analysis consisted of cross-sectional and observational studies. We could not quantify the effect of collinearity. Conclusions: Individuals with CHD appear to have at least moderate deficits in executive functions. Given the growing population of people with CHD, more attention should be devoted to identifying executive dysfunction in this vulnerable group.

Abstract Background. Parental separation is a very common childhood adversity. The association between other adverse childhood experiences and an increased risk of psychosis has been reported. However, the evidence on the risk of psychosis for children of separated parents is limited. In this systematic review, cohort, case–control, and cross-sectional studies, comparing the risk of psychotic disorders for people with and without separated parents, were searched, critically appraised, and summarized. Methods. Studies were searched in PubMed, EMBASE, PsycINFO, and the Web of Science, from database inception to September 2019. A meta-analysis, using random-effects models, was undertaken to obtain pooled estimates of the risk of psychosis among participants with separated parents. Results. Twelve studies, with 305,652 participants from 22 countries, were included in the review. A significantly increased risk of psychosis for those with separated parents was observed, with a pooled odds ratio: 1.53 (95% confidence interval [CI]: 1.29–1.76), p < 0.001. The association remained significant when cohort, case–control, and cross-sectional studies were analyzed separately. The five cohort studies included in this review showed and increased risk of psychosis with odds ratio: 1.47 (95% CI: 1.26–1.69), p < 0.001. Conclusions. Parental separation is a common childhood adversity associated with an increased risk of psychosis. Although the risk for an individual child of separated parents is still low, given the high proportion of couple that separate, the increased rates of psychosis may be substantial in the population. Further studies on the risk of psychosis in those with separated parents, and the explanatory factors for this association, are required.

Data on the dose-dependent effects of smoking and smoking cessation on tooth loss are scarce. We hypothesized that smoking has both dose- and time-dependent effects on tooth loss incidence. We used longitudinal data on tobacco use and incident tooth loss in 43,112 male health professionals, between 1986 and 2002. In multivariate Cox models, current smokers of 5 to 14 and 45+ cigarettes daily had a two-fold (HR, 1.94; 95% CI, 1.72, 2.18) and three-fold (HR, 3.05; 95% CI, 2.38, 3.90) higher risk of tooth loss, respectively, compared with never-smokers. Risk decreased with increasing time since cessation, but remained elevated by 20% (95% CI, 16%, 25%) for men who had quit 10+ years before. Current pipe/cigar smokers had a 20% (95% CI, 1.11, 1.30) increased risk of tooth loss compared with never- and former smokers of pipes/cigars.

Abstract Background: To investigate the bidirectional association between tooth loss and hypertensionMethods: PubMed, EMBASE, OVID were searched through May, 2020. Longitudinal and cross-sectional studies reporting the association between tooth loss and hypertension were included. We quantitatively analyzed the basic framework and study characteristics, and then pooled estimate effects with 95% confidence intervals (CIs) of outcomes of each included studies using random-effects meta-analysis.Results: This systematic review included sixteen studies involving about 188,000 participants. Quantitatively summarized results suggested, compared to individuals who have lost fewer than ten teeth, there was no significantly difference in the incidence of hypertension among participants who lost more than ten teeth (OR: 1.09, 95%CI: 0.93,1.28). Besides, there is no significant difference of incident hypertension between individuals who ever lost teeth and never lost teeth (OR:1.03, 95% CI: 0.85,1.25). There was a significant association between hypertension and incidence of tooth loss (OR: 1.33, 95% CI: 1.04,1.70). Subgroup analysis by study design, age, gender ratio and religion showed statistically significant association between hypertension and incidence of tooth loss in specific subgroups.Conclusions: This meta-analysis identified hypertension as a significantly risk factor of tooth loss while tooth loss was not an efficient predictor for incident hypertension. Considering the limited number of available researches and drawback of cross-sectional studies, more high-quality prospective studies of large sample sizes are needed to understand details of this bidirectional association. Since both tooth loss and hypertension are worldwide problems, our study provides new and comprehensive evidence for the prevention in oral complication of hypertensive patients.
