The Relationship

Subclinical hypothyroidism (SCH) has been found to be associated with an increased risk of cardiovascular diseases. However, there is no clear consensus on the relationship between SCH and hypertension (HTN). We sought to investigate the association between SCH and incident HTN in women. MEDLINE and EMBASE databases were searched for studies that reported the incidence of HTN in females with SCH versus without SCH. Pooled odds ratio (OR) and 95% confidence interval (CI) of the outcome were obtained using a random-effects model. Studies were also divided into the middle-aged (mean age < 65) and the older (mean age ≥ 65) subgroups, and a subgroup analysis was performed to examine the potential age-effect on the association between SCH and HTN. Nine studies with a total of 21,972 subjects met the inclusion criteria. SCH was found to be positively associated with HTN (OR = 1.32, 95% CI = 1.02–1.71). Such association varied depending on the age of women. In the middle-aged subgroup, SCH was more positively associated with HTN (OR = 1.64, 95% CI = 1.18–2.27), while there was no significant association in the older subgroup (OR = 0.97, 95% CI = 0.80–1.16). Our study showed that the middle-aged females with SCH had an increased risk of HTN, while there was no significant association in the older females with SCH.

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.

The Relationship

Context Infant colic is a common and distressing disorder of early infancy. Its etiology is unknown, making treatment challenging. Several articles have suggested a link to migraine. Objective The objective of this article was to perform a systematic review and, if appropriate, a meta-analysis of the studies on the relationship between infant colic and migraine. Data sources Studies were identified by searching PubMed and ScienceDirect and by hand-searching references and conference proceedings. Study selection For the primary analysis, studies specifically designed to measure the association between colic and migraine were included. For the secondary analysis, studies that collected data on colic and migraine but were designed for another primary research question were also included. Data extraction Data were abstracted from the original studies, through communication with study authors, or both. Two authors independently abstracted data. Main outcomes and measures The main outcome measure was the association between infant colic and migraine using both a fixed-effects model and a more conservative random-effects model. Results Three studies were included in the primary analysis; the odds ratio for the association between migraine and infant colic was 6.5 (4.6–8.9, p < 0.001) for the fixed-effects model and 5.6 (3.3–9.5, p = 0.004) for the random-effects model. In a sensitivity analysis wherein the study with the largest effect size was removed, the odds ratio was 3.6 (95% CI 1.7–7.6, p = 0.001) for both the fixed-effects model and random-effects model. Conclusions In this meta-analysis, infant colic was associated with increased odds of migraine. If infant colic is a migrainous disorder, this would have important implications for treatment. The main limitation of this meta-analysis was the relatively small number of studies included.

Abstract Objective Macrolide antibiotics are among the most commonly used antibiotics; the association of macrolide antibiotics exposure with sensorineural hearing loss (SNHL) has been hypothesized. A systematic search was conducted in PubMed, EMBASE and Cochrane Library from inception to 15 July 2019 to identify studies used macrolide antibiotics for any indication. The results were reported as odds ratio (OR) with 95% confidence interval (CI) using random-effects model to derive the association of macrolide antibiotics exposure with SNHL. The objective of this meta-analysis was to estimate the association of macrolide antibiotics exposure and SNHL from up-to-date evidence. Key findings Nine studies met the inclusion criteria. There was no statistically significant association between macrolide antibiotics exposure and SNHL; the OR was 1.20 (95% CI: 0.96 to 1.49). No significant association was found with any of the subgroup meta-analyses. Summary Whilst the frequency of SNHL was higher with macrolide antibiotics exposure compared with controls, overall, no association was found between macrolide antibiotics and SNHL.

Objectives: The relationship between Noggin ( NOG) and methylenetetrahydrofolate reductase and nonsyndromic cleft lip and palate (NSCLP) has been reported participate in craniofacial development but need further evidence. To indicate the susceptibility between the 2 genes and NSCLP, rs227731 and rs1801131 polymorphisms were included in the present research. This research may provide some genetic clues for disease detection and surveillance. Design: Seventeen studies including 4023 cases and 5691 controls were provided for meta-analysis, and odds ratio (OR) with 95% CI were obtained to estimate NSCLP risk. Results: Our analysis suggested potential association of rs227731C on increasing the risk of NSCLP in the Caucasian group and total group but not Asian group under all models: allele (OR = 1.45, 95% CI = 1.21-1.75, P < .0001), homozygote (OR = 2.03, 95% CI = 1.42-2.90, P < .0001), heterozygote (OR = 1.44, 95% CI = 1.19-1.73, P = .0001), dominant (OR = 1.61, 95% CI = 1.27-2.04, P < .0001), and recessive models (OR = 1.63, 95% CI = 1.25-2.12, P = .0003). Besides, increased risk is related to rs1801131 in Asian group under 3 models: allele (OR = 1.24, 95% CI = 1.06-1.44, P = .006), heterozygote (OR = 1.24, 95% CI = 1.02-1.52, P = .03), and dominant models (OR = 1.29, 95% CI = 1.06-1.56, P = .009). Conclusions: Our analysis indicates polymorphisms rs227731 and rs1801131 are associated with NSCLP, with predominance of different ethnic group and deepen understanding of NSCLP.

Background: As society ages, the incidence of osteoporosis increases. In several studies, cadmium (Cd) is thought to be related to osteoporosis. However, there are conflicting reports about the relationship between Cd and the risk of osteoporosis and osteopenia. Therefore, the purpose of this meta-analysis was to explore the relationship between Cd and osteoporosis and osteopenia.Methods: Through a review of the literature, articles published in PubMed as of December 2020 were identified and the references of related publications and reviews were reviewed. Ultimately, 17 eligible articles were selected to determine the relationship between blood and urine Cd concentrations for the risk of osteoporosis or osteopenia. In this study, we performed a classification analysis, heterogeneity test, subgroup analysis, and evaluated publication bias.Results: A total of 17 studies were included, including seven on blood Cd and 10 on urine Cd. By combining the odds ratio (OR) and 95% confidence interval (CI) for the lowest and highest categories, the odds ratio of blood Cd concentration that increased the risk of osteoporosis or osteopenia was OR 1.21 (95% CI: 0.84–1.58) and that of urine Cd concentration that increased the risk of osteoporosis or osteopenia was OR 1.80 (95% CI: 1.42–2.18), and the results of the subgroup analysis were also consistent.Conclusions: Our research indicates that while urine cadmium (Cd) concentration may be related to increased risk of osteoporosis and osteopenia, blood Cd concentration may not. Therefore, compared to blood Cd concentration, urine Cd concentration may be more reliable as a risk factor for osteoporosis and osteopenia. This result should be interpreted with caution. Currently. research on the relationship between Cd concentration and osteoporosis and osteopenia is limited, thus, further large, high-quality prospective studies are required to elucidate the relationship between Cd concentration and osteoporosis and osteopenia.

Abstract Background Several primary studies evaluated the association between rhinitis and the incidence of depression and yielded inconsistent results. We conducted a meta-analysis of studies evaluating the association between rhinitis and depression. Methods We searched the EMBASE, PubMed and Cochrane Library databases for studies published in English before April 1, 2019. The studies were included if they reported any type of rhinitis in relation to depression. Two authors independently extracted the data. The odds ratios (ORs) were pooled using a random-effects model. Stratified analyses were conducted to evaluate the association. Results Among the 3472 initially identified studies, we included 14 studies involving a total of 19.36 ± 1.1 million participants according to predefined inclusion criteria. The associations between rhinitis (R), allergic rhinitis (AR), and nonallergic rhinitis (NAR) and depression were significant with ORs of 1.86 (95% CI 1.32 to 2.62, p < 0.05), 1.54 (95% CI 1.24 to 1.90, p < 0.05), and 2.15 (95% CI 1.49 to 3.09, p < 0.05), respectively. The results were consistent and statistically significant in all subgroup analyses. Conclusions Rhinitis was associated with an increased risk of depression. Further prospective studies involving large sample sizes are required to confirm the results by considering more confounders and clarify the mechanisms.

This meta-analysis was conducted to assess the consistency and strength of the relationship between polymorphism of IL-2 -330T/G and susceptibility to pulmonary tuberculosis (TB). PubMed, Web of Knowledge and CNKI were searched to find eligible studies about the relationship between IL-2 -330T/G polymorphism and susceptibility to pulmonary TB. A total of eight studies comprising 971 cases and 1519 controls were grouped together for the purpose of elucidating the relationship between polymorphism of IL-2 -330T/G and pulmonary TB susceptibility. The allele model (G vs. T: odds ratio (OR) = 1.34; 95% confidence interval (CI) 1.05–1.71, Phet = 0.001) and the recessive model (GG+GT vs. TT: OR = 1.60; 95% CI 1.08–2.38, Phet = 0.0001) showed an increased risk of development of pulmonary TB. However, the homozygous model (GG vs. TT: OR = 1.74; 95% CI 0.98–3.09, Phet = 0.0005) and the dominant model (GG vs. TT + TG: OR = 1.30; 95% CI = 0.80-2.14, Phet =  0.001) failed to show an increased incidence of pulmonary TB. When analysis was stratified by ethnicity, no obvious associations were identified in the Caucasian subgroup under all four genetic models. Additionally, heterogeneity disappeared in the analysis of Caucasian subgroup. Our combined data suggested that there was no association between IL-2 -330T/G polymorphism and pulmonary TB among Caucasians.

Background and Aims: Several studies have shown that host genetic factors can be associated with the risk of developing Helicobacter pylori infections. Therefore, we evaluated the most prevalent toll-like receptors (TLRs) polymorphisms in Helicobacter pylori positive subjects and their possible role in susceptibility to Helicobacter pylori infections. Materials and Methods: Using related keywords, an independent search in the electronic databases including PubMed, Scopus, Google Scholar and ISI web of knowledge was performed to collect studies evaluating, until January 15, 2019, polymorphisms in the TLR 1 to 13 genes and their association with susceptibility to Helicobacter pylori infection. A total of 18 articles met our inclusion criteria and thus were included in the meta-analysis. Results: In this meta-analysis, a significantly increased risk of Helicobacter pylori infection was observed in subjects carrying TLR2 rs3804099 (TT vs. CC: odds ratio = 2.209, 95% CI: 1.283-3.804), TLR4 rs4986790 (A allele vs. G allele: odds ratio = 2.987, 95% CI: 1.899-4.697), TLR4 rs4986791 (C allele vs. T allele: odds ratio = 5.469, 95% CI: 13.432-8.713), TLR4 rs4986791 (CC vs. TT: odds ratio = 7.974, 95% CI: 2.682-23.706), TLR4 rs10759932 (TT vs. CC: odds ratio = 3.180, 95% CI: 1.022-9.890), TLR4 rs1927914 (C allele vs. T allele: odds ratio = 8.831, 95% CI: 4.222-18.470), and TLR9 rs352140 (CC vs. CT: odds ratio = 1.878, 95% CI: 1.071-3.290) polymorphisms. Conclusions: This meta-analysis indicated that TLR2 rs3804099, TLR4 rs4986790, TLR4 rs4986791, TLR4 rs10759932, TLR4 rs1927914 and TLR9 rs352140 polymorphisms are associated with increased susceptibility to Helicobacter pylori infections.

Background: The purpose of this study is to systematically review the literature addressing the effectiveness of legislative smoking bans and anti-tobacco media campaigns in reducing smoking among women. Methods: MEDLINE, PubMed, CINAHL, and ABI/INFORM were searched for studies published from 2005 onwards. Meta-analysis was conducted using a random effects model and subgroup analysis on pre-selected characteristics. Results: In total, 652 articles were identified, and five studies satisfied the inclusion criteria. The studies varied from school-based to workplace settings and had a total of 800,573 women participants, aged 12 to 64 years old. Three studies used legislative bans, one study used anti-tobacco campaigns and another one used both as their intervention. The overall pooled effect of the five studies yielded an odds ratio (OR) = 1.137 (C.I. = 0.976–1.298 and I2 = 85.6%). Subgroup analysis by intervention revealed a significant pooled estimate for studies using legislative smoking bans OR = 1.280 (C.I. = 1.172–1.389 and I2 = 0%). Conclusion: Legislative smoking bans were found to be associated with a reduction in the smoking rates among women compared to anti-tobacco media campaigns. Further research in this area is needed.
