Meta-Analysis Review
BACKGROUND
Molecular pathways found to be important in pulmonary fibrosis are also involved in cancer pathogenesis, suggesting common pathways in the development of pulmonary fibrosis and lung cancer.
RESEARCH QUESTION
Is pulmonary fibrosis from exposure to occupational carcinogens an independent risk factor for lung cancer?
STUDY DESIGN AND METHODS
A comprehensive search of PubMed, Embase, Web of Science and Cochrane databases with over 100 search terms regarding occupational hazards causing pulmonary fibrosis was conducted. After screening and extraction, quality of evidence and eligibility criteria for meta-analysis were assessed. Meta-analysis was performed using a random-effects model.
RESULTS
52 studies were identified for systematic review. Meta-analysis of subgroups identified silicosis as a risk factor for lung cancer when investigating odds ratios for silicosis in autopsy studies (OR 1.47, 95% CI 1.13-1.90) and for lung cancer mortality in patients with silicosis (OR 3.21, 95% CI 2.67-3.87). Only considering studies with an adjustment for smoking as a confounder identified a significant increase in lung cancer risk (OR 1.58, 95% CI 1.34-1.87). However, due to a lack of studies including cumulative exposure, no adjustments could be included. In a qualitative review, no definitive conclusion could be reached for asbestosis and silicosis as independent risk factors for lung cancer, partly because the studies did not take cumulative exposure into account.
INTERPRETATION
This systematic review confirms the current knowledge regarding asbestosis and silicosis, indicating a higher risk of lung cancer in exposed individuals compared to exposed workers without fibrosis. These individuals should be monitored for lung cancer, especially when asbestosis or silicosis is present.

Review
Foodborne enteritis is a major disease burden globally. Two of the most common causative bacterial enteropathogens in humans are Campylobacter and Salmonella species which are strongly associated with the consumption of raw or contaminated chicken. The poultry industry has approached this issue by use of a multi-hurdle method across the production chain to reduce or eliminate this risk. The use of poultry vaccines is one of these control methods. A systematic review and meta-analysis of vaccination effects against caecal Campylobacter and Salmonella were performed on primary research published between 2009 and 2022. Screening was conducted by three reviewers with one reviewer performing subsequent data extraction and one reviewer performing the risk of bias assessment. The confidence in cumulative evidence was evaluated based on the GRADE method. Meta-analyses were performed using standardised mean differences (SMDs) with additional analyses and random effects regression models on intervention effects grouped by the vaccine type. A total of 13 Campylobacter and 19 Salmonella studies satisfied the eligibility criteria for this review. Many studies included multi-arm interventions, resulting in a total of 25 Campylobacter and 34 Salmonella comparators which were synthesised. The analyses revealed a large reduction in pathogen levels; however, many effects required statistical adjustment due to unit of analysis errors. There was a moderate level of confidence in the reduction of Campylobacter by 0.93 SMD units (95% CI: −1.275 to −0.585; p value < 0.001) and a very low level of confidence in the reduction of Salmonella by 1.10 SMD units (95% CI: −1.419 to −0.776; p value < 0.001). The Chi2 test for heterogeneity (p value 0.001 and <0.001 for Campylobacter and Salmonella, respectively) and the I2 statistic (52.4% and 77.5% for Campylobacter and Salmonella, respectively) indicated high levels of heterogeneity in the SMDs across the comparators. The certainty of gathered evidence was also affected by a high risk of study bias mostly due to a lack of detailed reporting and, additionally for Salmonella, the presence of publication bias. Further research is recommended to source areas of heterogeneity, and a conscious effort to follow reporting guidelines and consider units of analysis can improve the strength of evidence gathered to provide recommendations to the industry.

Review
BACKGROUND AND PURPOSE
Patients with migraine are at increased risk of stroke. The aim was to systematically review the current literature on the association between migraine and atrial fibrillation, which is a relevant risk factor for stroke.
METHODS
PubMed was searched for 'migraine' AND 'atrial fibrillation' and selected original investigations on the association of migraine and atrial fibrillation for our analysis. Articles without original data, such as guidelines, narrative reviews, editorials and others, were excluded.
RESULTS
In all, 109 publications were found. Twenty-two were included and analysed for this review. The population-based Atherosclerosis Risk in Communities study showed a significant association of migraine with visual aura and incident atrial fibrillation (hazard ratio 1.30, 95% confidence interval 1.03-1.62, p = 0.02), but not for migraine without aura, compared to non-headache persons after multivariable adjustment for vascular risk factors. An even larger population-based study in Denmark confirmed this association (odds ratio 1.25, 95% confidence interval 1.16-1.36). Studies investigating patients with ischaemic stroke and migraine are methodologically insufficient and provide contradictory results. Ablation therapy for atrial fibrillation in patients with migraine might reduce migraine attacks, but transient post-ablation new-onset migraine-like headaches in persons without a history of migraine have also been reported.
CONCLUSION
Population-based studies indicate a significant association of migraine with aura and atrial fibrillation. In practical terms, screening for atrial fibrillation in patients who have a long history of migraine might be reasonable, whereas in patients with stroke or other disorders and migraine extensive screening for atrial fibrillation should be performed as in all patients without migraine.

Review
BACKGROUND
There is growing evidence that breastfeeding has short- and long-term cardiovascular health benefits for mothers. The objectives of this systematic review were to examine the association between breastfeeding and maternal cardiovascular risk factors and outcomes that have not previously been synthesized systematically, including metabolic syndrome, hypertension and cardiovascular disease.
METHODS AND FINDINGS
This systematic review meets PRISMA guidelines. The MEDLINE, EMBASE and CINAHL databases were systematically searched for relevant publications of any study design from the earliest publication date to March 2016. The reference lists from selected articles were reviewed, and forward and backward referencing were conducted. The methodological quality of reviewed articles was appraised using validated checklists. Twenty-one studies meeting the inclusion criteria examined the association between self-reported breastfeeding and one or more of the following outcomes: metabolic syndrome/metabolic risk factors (n = 10), inflammatory markers/adipokines (n = 2), hypertension (n = 7), subclinical cardiovascular disease (n = 2), prevalence/incidence of cardiovascular disease (n = 3) and cardiovascular disease mortality (n = 2). Overall, 19 studies (10 cross-sectional/retrospective, 9 prospective) reported significant protective effects of breastfeeding, nine studies (3 cross-sectional/retrospective, 5 prospective, 1 cluster randomized controlled trial) reported non-significant findings and none reported detrimental effects of breastfeeding. In most studies reporting significant associations, breastfeeding remained associated with both short- and long-term maternal cardiovascular health risk factors/outcomes, even after covariate adjustment. Findings from several studies suggested that the effects of breastfeeding may diminish with age and a dose-response association between breastfeeding and several metabolic risk factors. However, further longitudinal studies, including studies that measure exclusive breastfeeding, are needed to confirm these findings.
CONCLUSIONS
The evidence from this review suggests that breastfeeding is associated with cardiovascular health benefits. However, results should be interpreted with caution as the evidence gathered for each individual outcome was limited by the small number of observational studies. Additional prospective studies are needed.

Review
Pregnancy and lactation deplete nutrients essential to the neurotransmission system. This may be one reason for the increased risk of depression during the perinatal period. The objective of the present review was to systematically review the literature and summarise evidence on whether blood nutrient levels influence the risk of perinatal depression. PubMed, EMBASE and CINAHL databases were searched for studies of any design. A total of twenty-four articles of different designs were included, representing 14 262 subjects. We extracted data on study population, depression prevalence, nutrients examined, deficiency prevalence, timing of assessment, reporting, analysis strategy and adjustment factors. In all, fourteen studies found associations of perinatal depression with lower levels of folate, vitamin D, Fe, Se, Zn, and fats and fatty acids, while two studies found associations between perinatal depression and higher nutrient levels, and eight studies found no evidence of an association. Only ten studies had low risk of bias. Given the methodological limitations and heterogeneity of study approaches and results, the evidence for a causal link between nutritional biomarkers and perinatal depression is still inconclusive. High-quality studies in deficient populations are needed.

Meta-Analysis Review
BACKGROUND
The longer term cardiovascular effects of fertility therapy are unknown.
OBJECTIVES
The aim of this study was to summarize data linking fertility therapy with subsequent cardiovascular outcomes.
METHODS
We systematically searched published reports for studies addressing the question "does fertility therapy increase the risk of longer term cardiovascular outcomes?" We included: 1) human studies; 2) case control, cohort, or randomized designs with 3) exposure to fertility therapy and 4) cardiovascular outcomes clearly reported; 5) presence of comparison group; 6) minimum 1-year follow-up; and 7) adjustment for age. Two independent reviewers screened abstracts, titles, and full texts, and assessed study quality. We used the DerSimonian and Laird random-effects models to pool hazard ratios (HRs) with 95% confidence intervals (CIs) of the following outcomes: acute cardiac event; stroke; venous thromboembolism; hypertension; and diabetes mellitus, comparing women who received fertility therapy with those who did not.
RESULTS
Six observational studies met inclusion criteria including 41,910 women who received fertility therapy and 1,400,202 women who did not. There was no increased risk of a cardiac event (pooled HR: 0.91; 95% CI: 0.67 to 1.25; I = 36.6%), or diabetes mellitus (pooled HR: 0.93; 95% CI: 0.87 to 1.001; I = 0%). Results were not pooled for hypertension (I = 95.0%) and venous thromboembolism (I = 82.3%). There was a trend toward higher risk of stroke (pooled HR: 1.25; 95% CI: 0.96 to 1.63; I = 0%).
CONCLUSIONS
The small number of studies and significant heterogeneity precludes definitive reassurance about the longer term cardiovascular safety of these treatments, particularly stroke. Future studies are needed to address ongoing knowledge gaps in this area.

Review
The importance of family functioning in the development of child and adult psychopathology has been widely studied. However, the relationship between partners' adjustment and family health is less studied. This paper aims to describe and summarize research that analyzes the relationship between partners' adjustment and family health. A systematic review was conducted in the PubMed, PsycINFO, Scopus, Lilacs, Psicodoc, Cinahl, and Jstor databases. Inclusion criteria were as follows: articles published from 2012 to 2019 in English, Spanish, or Portuguese. Data were extracted and organized according to the family health model: family climate, integrity, functioning, and coping. Initially, 835 references were identified, and 24 articles were assessed for quality appraisal. Finally, 20 publications were selected. Results showed that couple adjustment was an important factor that triggered the emotional climate of the family, was positively intercorrelated to parenting alliance or coparenting, and contributed to family efficacy and help when facing stressful life events. Findings revealed a consensus about the relationship between couple dyadic adjustment and family health. The results could orientate interventions to promote well-being and to increase quality of life and family strength. Health professionals should thoroughly study couple relationships to identify risk factors, assess family skills, and promote family health.

Nutrition Reviews Nov 2017Pancreatic cancer has the highest case fatality rate of all major cancers. (Meta-Analysis)
Meta-Analysis Review
CONTEXT
Pancreatic cancer has the highest case fatality rate of all major cancers.
OBJECTIVE
A systematic review using PRISMA guidelines was conducted to summarize the associations between dietary patterns and risk of pancreatic cancer.
DATA SOURCES
PubMed and Web of Science databases were searched for case-control and cohort studies published up to June 15, 2016.
STUDY SELECTION
Eligible studies included a dietary pattern as exposure and pancreatic cancer incidence or mortality as outcome and reported odds ratios, hazard ratios, or relative risks, along with corresponding 95%CIs.
DATA EXTRACTION
Important characteristics of each study, along with the dietary assessment instrument, the component foods or nutrients included in each dietary pattern or the scoring algorithm of a priori dietary patterns, were presented. For each dietary pattern identified, the estimate of association and the 95%CI comparing the highest versus the lowest category from the model with the most covariate adjustment were reported.
RESULTS
A total of 16 studies were identified. Among the 8 studies that examined data-driven dietary patterns, significant positive associations were found between pancreatic cancer risk and the Animal Products, Starch Rich, and Western dietary patterns, with effect estimates ranging from 1.69 to 2.40. Significant inverse relationships were found between risk of pancreatic cancer and dietary patterns designated as Fruits and Vegetables, Vitamins and Fiber, and Prudent, with effect estimates ranging from 0.51 to 0.55. Eight studies of a priori dietary patterns consistently suggested that improved dietary quality was associated with reduced risk of pancreatic cancer.
CONCLUSIONS
Better diet quality is associated with reduced risk of pancreatic cancer. The associations between dietary patterns and pancreatic cancer were stronger in case-control studies than in cohort studies and were stronger among men than among women.

Meta-Analysis Review
INTRODUCTION AND HYPOTHESIS
Numerous analytic observational studies assess family history as a risk factor for POP and report a wide range of associations. This review aims to systematically evaluate the role of family history of POP in relation to POP risk and its recurrence.
METHODS
A review was performed of the PubMed/MEDLINE database with search criteria specifying family history, risk factors, POP, and their synonyms as title/abstract keywords, as well as MESH terms, up to March 2020. We aggregated evidence across studies with fixed effects (FE) and random effects (RE) meta-analysis.
RESULTS
Forty-three articles underwent full-text review. Eighteen independent studies evaluating the relationship between family history of POP and POP risk in 3639 POP cases and 10,912 controls were eligible for meta-analysis. Four studies evaluating family history and POP recurrence in 224 recurrent cases and 400 non-recurrent cases were eligible for inclusion into another meta-analyses. A positive family history of POP is on average associated with 2.3- to 2.7-fold increased risk for POP (RE OR = 2.64; 95% CI = 2.07, 3.35) as well as a 1.4-fold increased risk for POP recurrence (FE OR = 1.44; 95% CI = 1.00, 2.08). Meta-analysis estimates of POP risk varied by study design, definition of family history, and model adjustment status. We found evidence that publication bias and recall bias are a possibility.
CONCLUSIONS
Family history of POP is a risk factor for both POP presence and recurrence. However, reported magnitudes may be overestimates due to confounding, recall bias, and publication bias.

Meta-Analysis Review
UNLABELLED
Diabetes mellitus (DM) may be a risk factor for venous thromboembolism (VTE) but results are inconsistent.
AIM
We conducted a systematic review and meta-analysis of epidemiologic studies to quantify the association between DM and VTE.
METHODS AND RESULTS
We included studies identified in PubMed, Web of Science, and CINAHL through 07/31/2014. We identified 19 studies that met our selection criteria. We pooled RRs using a random-effects model: the pooled RR for the association of DM with VTE was 1.10 (95% CI: 0.94-1.29). Between-study heterogeneity was explored with a forest plot, funnel plot, meta-regression, and a stratified analysis. Between-study heterogeneity was observed and not explained by study design, method of DM assessment, or degree of adjustment for confounding. Sensitivity analyses omitted one study at a time to assess the influence of any single study on the pooled estimate. These analyses indicated that one large study was highly influential; when this study was excluded, the pooled estimate increased and just reached statistical significance: 1.16 (95% CI: 1.01-1.34).
CONCLUSIONS
This meta-analysis suggests either no association or a modest positive one between DM and VTE in the general population. DM is unlikely to play a major role in VTE development.
