Meta-Analysis
BACKGROUND
While the incidence of inflammatory bowel disease (IBD) has stabilised in the West, it is still increasing in several newly industrialised countries.
AIMS
To investigate whether the environmental and dietary risk factors for IBD differ between Eastern and Western populations METHODS: We systematically searched PubMed, Embase, and Web of Science for studies published from inception through June 30, 2020. Data were pooled using a random effects model.
RESULTS
Overall, 255 studies were assessed. We identified 25 risk factors for IBD, seven of which were noted in both Eastern and Western populations: family history of Crohn's disease [CD] or ulcerative colitis [UC], former smoking (CD/UC), smoking (CD), appendicectomy (CD), tonsillectomy (CD), meat and meat products (CD), and vitamin D deficiency (UC). The remaining factors, including urban living, current smoking, antibiotics, oral contraceptives, caesarean section, isotretinoin, total energy, fat, cholesterol, fatty acids and their sub-classifications, eggs, and soft drinks, were associated with an increased risk of IBD in Western or Eastern populations only. We identified 21 protective factors for IBD, among which eight were common in the East and West: farm animals (CD/UC), Helicobacter pylori infection (CD/UC), multiple births (CD), physical activity (CD), history of breastfeeding (CD), pets (UC), current smoking (UC), and coffee intake (UC). Ten factors conferred protection against IBD in Western populations only, whereas eight factors conferred protection against IBD in Eastern populations only.
CONCLUSIONS
Numerous environmental and dietary factors influenced the development of IBD in both Western and Eastern populations, whereas certain factors influenced IBD risk differently in these populations.

Meta-Analysis
INTRODUCTION
It is established that higher prediagnostic circulating androgen and estrogen levels are associated with increased breast cancer risk in premenopausal and postmenopausal women. Pooled analyses in postmenopausal women report higher androgen and estrogen levels in current heavy cigarette smokers compared to nonsmokers. However, evidence among premenopausal women has been inconsistent.
AIMS AND METHODS
We conducted a systematic review and meta-analysis to estimate differences in standardized mean hormone levels among current premenopausal smokers compared to nonsmokers. We reviewed and collated publications with sex hormone levels by smoking status among healthy, premenopausal women who were nonusers of exogenous hormones, including oral contraceptives, using PubMed through December 2019. A random effects meta-analysis was conducted to combine the standardized mean differences (SMD) and 95% confidence intervals (CIs) for estradiol, progesterone, testosterone, dehydroepiandrosterone, dehydroepiandrosterone-sulfate, and sex hormone-binding globulin by smoking status. Findings were summarized by menstrual cycle phase and overall.
RESULTS
Nineteen published peer-reviewed articles were included. Significantly increased testosterone levels among smokers compared to nonsmokers were identified from cross-sectional studies with varied menstrual phase timing (SMD 0.14; 95% CI 0.0005, 0.29) and significantly increased dehydroepiandrosterone-sulfate levels were found over all phases (SMD 0.12; 95% CI 0.01, 0.22). However, substantial heterogeneity existed in these studies.
CONCLUSIONS
This meta-analysis suggests that smoking may increase blood androgen levels in healthy premenopausal women which may increase breast cancer risk; however, the differences were modest. Larger and covariate-adjusted studies with standardized collection over the menstrual cycle are needed to better understand this relationship and to reduce heterogeneity.
IMPLICATIONS
Existing research has described associations between high prediagnostic estradiol and androgen levels with breast cancer risk among premenopausal women and has established active smoking as a breast cancer risk factor. However, the smoking and circulating sex hormone associations among premenopausal women remain inadequately studied. In this meta-analysis, we identified an association between smoking and higher mean testosterone and dehydroepiandrosterone-sulfate levels with consideration of menstrual phase, providing additional information on smoking's potential pathway to premenopausal breast cancer.

Meta-Analysis
OBJECTIVE
To systematically evaluate the efficacy and safety of Weichang'an pill (, WCA) combined with Western Medicine (WM) for the treatment of gastrointestinal diseases.
METHODS
Eight databases, including China National Knowledge Infrastructure Database, Wanfang Data, China Science and Technology Journal Database, SinoMed, PubMed, Web of Science, Cochrane Library, and Embase, were searched for randomized controlled trials (RCTs) of WCA from inception to 30 September 2021. We independently screened the literature, extracted data, and then evaluated the bias risk, effectiveness, safety, and other indicators of the included articles.
RESULTS
A total of 33 RCTs were included in this study with 3368 patients. After analysis, it was found that WCA combined with WM could effectively prevent and treat antibiotic-associated gastrointestinal reaction, functional dyspepsia (FD), irritable bowel syndrome, rotavirus diarrhea (RVD), and ulcerative colitis (UC); no serious adverse reactions occurred. Moreover, compared with the control group, the experimental group showed significantly improved symptoms and some biochemical parameters.
CONCLUSIONS
WCA combined with WM for the treatment of gastrointestinal diseases had better clinical efficacy than the control group, without serious adverse reactions. Notably, in the treatment of FD, RVD, and UC, WCA improved clinical symptoms and biochemical indicator expression. Nevertheless, owing to the restricted quality and quantity of the literature, the results need to be further studied using high-quality RCTs.

Meta-Analysis Review
We assessed the available evidence regarding adverse effects on surrogate and patient-important health outcomes of third- and fourth-generation combined oral contraceptives among premenopausal women. We performed a systematic review and meta-analysis including randomized controlled trials and observational studies comparing third- and fourth-generation combined oral contraceptives with other generation contraceptives or placebo. Studies that enrolled women aged 15 to 50 years, with at least three cycles of intervention and 6 months of follow-up were included. A total of 33 studies comprising 629,783 women were included. Low-density lipoprotein cholesterol levels were significantly lower in fourth-generation oral contraceptives (mean differences (MD): -0.24 mmol/L; [95% CI -0.39 to -0.08]), while total cholesterol was significantly increased in levonorgestrel users when compared to third-generation oral contraceptives (MD: 0.27 mmol/L; [95% CI 0.04 to 0.50]). A decreased arterial thrombosis incidence was shown in fourth-generation oral contraceptive users, as compared to levonorgestrel (incidence rate ratio (IRR): 0.41; [95% CI 0.19 to 0.86]). No difference was found in the occurrence of deep venous thrombosis between fourth-generation oral contraceptives and levonorgestrel users (IRR: 0.91; [95% CI 0.66 to 1.27]; p = 0.60; I = 0%). Regarding the remaining outcomes, data were heterogeneous and showed no clear difference. In premenopausal women, the use of third- and fourth-generation oral contraceptives is associated with an improved lipid profile and lower risk of arterial thrombosis. Data were inconclusive regarding the rest of outcomes assessed. This review was registered in PROSPERO with CRD42020211133.

Review
OBJECTIVE
The aim of this review and meta-analysis was to assess the effects and safety of modified Si-Miao pill (mSMP) in treatment of rheumatoid arthritis.
DESIGN
A systematic literature search was carried out in eight databases from their available dates of inception to April 2020. After screening, fifteen randomized, controlled trials (RCTs) comparing the effects and safety of mSMP in combination with western medicine (including disease-modifying antirheumatic drugs (DMARDs) and nonsteroidal anti-inflammatory drugs (NSAIDs)) in treating rheumatoid arthritis patients were included after screening.
RESULTS
In comparison with DMARDs, or coadministration of DMARDs and NSAIDs, mSMP in combination with western medicine significantly lowered erythrocyte sedimentation rate (mean difference (MD) = -10.61, 95% confidence interval (CI) [-12.19, -9.03]), C-reactive protein (MD = -6.50, 95% CI [-8.43, -4.56]), rheumatoid factors (MD = -17.31, 95% CI [-24.34, -10.27]), swollen joint count (MD = -1.63, 95% CI [-2.29, -0.97]), tender joint count (MD = -1.98, 95% CI [-2.34, -1.62]), and morning stiffness time (MD = -24.37, 95% CI [-29.41, 19.33]) and ameliorated the condition of patients (odds ratio (OR) = 3.69, 95% CI [2.64, 5.14]). Additionally, mSMP in combination with western medicine seemed safer (OR = 0.49, 95% CI [0.30, 0.81]).
CONCLUSION
The results of the meta-analysis study have shown that mSMP in combination with western medicine therapies appears to be more effective and safer than western medicine alone in the treatment of rheumatoid arthritis including reducing inflammatory markers and adverse events and improving symptoms. Howbeit, more high-grade, large-scale RCTs of mSMP in various countries and regions are still needed.

Meta-Analysis
OBJECTIVE
To compare between different combined oral contraceptive pills (COCPs) as part of the update of the International Evidence-Based Guidelines on the Assessment and Management of polycystic ovary syndrome (PCOS).
DESIGN
A systematic review and meta-analysis was performed, Prospero CRD42022345640.
METHODS
MEDLINE, EMBASE, All EBM, CINAHL, and PsycINFO was searched on July, 8, 2022, for studies including women with PCOS, comparing 2 different COCPs in randomized controlled trials.
RESULTS
A total of 1660 studies were identified, and 19 randomized controlled trials (RCTs) were included.Fourth-generation COCP resulted in lower body mass index (BMI) (mean difference [MD] 1.17 kg/m2 [95% confidence interval {CI} 0.33; 2.02]) and testosterone (MD 0.60 nmol/L [95% CI 0.13; 1.07]) compared with third-generation agents, but no difference was seen in hirsutism.Ethinyl estradiol (EE)/cyproterone acetate (CPA) was better in reducing hirsutism as well as biochemical hyperandrogenism (testosterone [MD 0.38 nmol/L {95% CI 0.33-0.43}]) and BMI (MD 0.62 kg/m2 [95% CI 0.05-1.20]) compared with conventional COCPs.There was no difference in hirsutism between high and low EE doses. No evidence regarding natural estrogens in COCP was identified.
CONCLUSION
With current evidence, combined regimens containing an antiandrogen (EE/CPA) may be better compared with conventional COCPs in reducing hyperandrogenism, but EE/CPA will not be recommended as a first-line COCP treatment by the pending PCOS guideline update, due to higher venous thrombotic events (VTE) risk in the general population. Later-generation progestins offer theoretical benefits, but better evidence on clinical outcomes is needed in women with PCOS.
TRIAL REGISTRATION
The protocol for the systematic review was registered prospectively in Prospero, CRD42022345640.

Review
The prognosis of various cardiovascular diseases eventually leads to heart failure (HF). An energy metabolism disorder of cardiomyocytes is important in explaining the molecular basis of HF; this will aid global research regarding treatment options for HF from the perspective of myocardial metabolism. There are many drugs to improve myocardial metabolism for the treatment of HF, including angiotensin receptor blocker-neprilysin inhibitor (ARNi) and sodium glucose cotransporter 2 (SGLT-2) inhibitors. Although Western medicine has made considerable progress in HF therapy, the morbidity and mortality of the disease remain high. Therefore, HF has attracted attention from researchers worldwide. In recent years, the application of traditional Chinese medicine (TCM) in HF treatment has been gradually accepted, and many studies have investigated the mechanism whereby TCM improves myocardial metabolism; the TCMs studied include Danshen yin, Fufang Danshen dripping pill, and Shenmai injection. This enables the clinical application of TCM in the treatment of HF by improving myocardial metabolism. We systematically reviewed the efficacy of TCM for improving myocardial metabolism during HF as well as the pharmacological effects of active TCM ingredients on the cardiovascular system and the potential mechanisms underlying their ability to improve myocardial metabolism. The results indicate that TCM may serve as a complementary and alternative approach for the prevention of HF. However, further rigorously designed randomized controlled trials are warranted to assess the effect of TCM on long-term hard endpoints in patients with cardiovascular disease.

Review
There is limited understanding of the potential relationship between the risk of colorectal cancer and oral contraceptive use among women of different ages. Further investigation on the issue helps develop an informed choice of contraception. Data for this meta-analysis were derived from case-control and cohort studies of colorectal cancer and oral contraceptive use conducted between June 2000 and May 2022. The studies had a very high heterogeneity, as shown by an I of 99%, and a confidence interval of 95% was considered significant. Other results from the meta-analysis were as follows; Heterogeneity: Chi = 585.13, df = 6 (P < 0.00001). A test of the overall effect of ever use versus never use of oral contraceptives was Z = 21.85 (P < 0.00001). All the studies had a pooled risk ratio (RR) of 0.53. The use of oral contraceptives is associated with reduced risk of developing colorectal cancer. There is a need for further research into the biological mechanisms underlying these relationships, which may lead to insights into potential preventive interventions for colorectal carcinogenesis in women. The keywords used to locate studies included in this meta-analysis include Keywords targeting oral contraceptives included oral contraceptive pills, and birth control pills. Search keywords targeting colorectal carcinogenesis included neoplasms, tumors, or colon and rectal cancer.

Psychotherapies are first-line treatments for most mental disorders, but their absolute outcomes (i.e., response and remission rates) are not well studied, despite the relevance of such information for health care users, providers and policy makers. We aimed to examine absolute and relative outcomes of psychotherapies across eight mental disorders: major depressive disorder (MDD), social anxiety disorder, panic disorder, generalized anxiety disorder (GAD), specific phobia, post-traumatic stress disorder (PTSD), obsessive-compulsive disorder (OCD), and borderline personality disorder (BPD). We used a series of living systematic reviews included in the Metapsy initiative (www.metapsy.org), with a common strategy for literature search, inclusion of studies and extraction of data, and a common format for the analyses. Literature search was conducted in major bibliographical databases (PubMed, PsycINFO, Embase, and the Cochrane Register of Controlled Trials) up to January 1, 2023. We included randomized controlled trials comparing psychotherapies for any of the eight mental disorders, established by a diagnostic interview, with a control group (waitlist, care-as-usual, or pill placebo). We conducted random-effects model pairwise meta-analyses. The main outcome was the absolute rate of response (at least 50% symptom reduction between baseline and post-test) in the treatment and control conditions. Secondary outcomes included the relative risk (RR) of response, and the number needed to treat (NNT). Random-effects meta-analyses of the included 441 trials (33,881 patients) indicated modest response rates for psychotherapies: 0.42 (95% CI: 0.39-0.45) for MDD; 0.38 (95% CI: 0.33-0.43) for PTSD; 0.38 (95% CI: 0.30-0.47) for OCD; 0.38 (95% CI: 0.33-0.43) for panic disorder; 0.36 (95% CI: 0.30-0.42) for GAD; 0.32 (95% CI: 0.29-0.37) for social anxiety disorder; 0.32 (95% CI: 0.23-0.42) for specific phobia; and 0.24 (95% CI: 0.15-0.36) for BPD. Most sensitivity analyses broadly supported these findings. The RRs were significant for all disorders, except BPD. Our conclusion is that most psychotherapies for the eight mental disorders are effective compared with control conditions, but absolute response rates are modest. More effective treatments and interventions for those not responding to a first-line treatment are needed.

Obstetrics and Gynecology Jan 2024To estimate the effect of medical management on the size of ovarian endometriomas. (Meta-Analysis)
Meta-Analysis
OBJECTIVE
To estimate the effect of medical management on the size of ovarian endometriomas.
DATA SOURCE
Online databases were searched from inception to October 2022, including Ovid MEDLINE, Ovid EMBASE, PubMed, EBM Reviews-Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials.gov , and Web of Science.
METHODS OF STUDY SELECTION
Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we included all English-language, full-text articles that reported on change in endometrioma size (either diameter or volume) after medical interventions. Studies evaluating surgical interventions or postoperative recurrence were excluded. All screening and data extraction were performed independently by two authors. Risk of bias assessment was performed with either the Cochrane Risk of Bias Tool for randomized controlled trials or a modified Newcastle-Ottawa Scale for observational studies.
TABULATION, INTEGRATION, AND RESULTS
After removal of duplicates, 9,332 studies were screened, with 33 full-text articles deemed eligible for inclusion. In the meta-analysis, dienogest showed significant reduction in cyst diameter (reduction 1.32 cm, 95% CI, 0.91-1.73, eight studies, n=418 cysts) and volume (mean difference of log-transformed volume 1.35, 95% CI, 0.87-1.83, seven studies, n=282 cysts). Similarly, significant reductions were seen with the oral contraceptive pill (OCP) (1.06 cm, 95% CI, 0.59-1.53, nine studies, n=455), gonadotropin-releasing hormone (GnRH) agonists (1.17 cm, 95% CI, 0.42-1.92, four studies, n=128 cysts), norethindrone acetate (0.6 cm, 95% CI, 0.27-0.94, two studies, n=88 cysts), and danazol (1.95 cm, 95% CI, 1.18-2.73, two studies, n=34 cysts). Norethindrone acetate with aromatase inhibitor was also effective in reducing endometrioma volume (mean difference of log-transformed volume 1.47, 95% CI, 0.16-2.78, two studies, n=34 cysts).
CONCLUSION
Medical management with dienogest, OCPs, GnRH agonists, norethindrone acetate, norethindrone acetate with aromatase inhibitor, or danazol can reduce the size of ovarian endometriomas.
