Global prevalence of osteoporosis among the world older adults: a comprehensive systematic review and meta-analysis

Abstract Background Osteoporosis is one of the most common bone system diseases that is associated with an increased risk of bone fractures and causes many complications for patients. With age, the prevalence of this disease increases so that it has become a serious problem among the elders. In this study, the prevalence of osteoporosis among elders around the world is examined to gain an understanding of its prevalence pattern. Methods In this systematic review and meta-analysis, articles that have focused on prevalence of osteoporosis in the world’s elders were searched with these key words, such as Prevalence, Osteoporosis, Elders, Older adult in the Science Direct, Embase, Scopus, PubMed, Web of Science (WoS) databases and Google Scholar search engine, and extracted without time limit until March 2020 and transferred to information management software (EndNote). Then, duplicate studies were eliminated and the remaining studies were evaluated in terms of screening, competence and qualitative evaluation based on inclusion and exclusion criteria. Data analysis was performed with Comprehensive Meta-Analysis software (Version 2) and Begg and Mazumdar test was used to check the publication bias and I2 test was used to check the heterogeneity. Results In a review of 40 studies (31 studies related to Asia, 5 studies related to Europe and 4 studies related to America) with a total sample size of 79,127 people, the prevalence of osteoporosis in the elders of the world; 21.7% (95% confidence interval: 18.8–25%) and the overall prevalence of osteoporosis in older men and women in the world, 35.3% (95% confidence interval: 27.9–43.4%), 12.5% (95% confidence interval: 9.3–16.7%) was reported. Also, the highest prevalence of osteoporosis in the elders was reported in Asia with; 24.3% (95% confidence interval: 20.9–28.1%). Conclusion The results of the present study showed that the prevalence of osteoporosis in the elders and especially elders' women is very high. Osteoporosis was once thought to be an inseparable part of elders’ lives. Nowadays, Osteoporosis can be prevented due to significant scientific advances in its causes, diagnosis, and treatment. Regarding the growing number of elderly people in the world, it is necessary for health policy-makers to think of measures to prevent and treat osteoporosis among the elders.

Prevalence Of Osteoporosis

Abstract Background Osteoporosis affects all sections of society, including families with people affected by osteoporosis, government agencies and medical institutes in various fields. For example, it involves the patient and his/her family members, and government agencies in terms of the cost of treatment and medical care. Providing a comprehensive picture of the prevalence of osteoporosis globally is important for health policymakers to make appropriate decisions. Therefore, this study was conducted to investigate the prevalence of osteoporosis worldwide. Methods A systematic review and meta-analysis were conducted in accordance with the PRISMA criteria. The PubMed, Science Direct, Web of Science, Scopus, Magiran, and Google Scholar databases were searched with no lower time limit up till 26 August 2020. The heterogeneity of the studies was measured using the I2 test, and the publication bias was assessed by the Begg and Mazumdar’s test at the significance level of 0.1. Results After following the systematic review processes, 86 studies were selected for meta-analysis. The sample size of the study was 103,334,579 people in the age range of 15–105 years. Using meta-analysis, the prevalence of osteoporosis in the world was reported to be 18.3 (95% CI 16.2–20.7). Based on 70 studies and sample size of 800,457 women, and heterogenicity I2: 99.8, the prevalence of osteoporosis in women of the world was reported to be 23.1 (95% CI 19.8–26.9), while the prevalence of osteoporosis among men of the world was found to be 11.7 (95% CI 9.6–14.1 which was based on 40 studies and sample size of 453,964 men.). The highest prevalence of osteoporosis was reported in Africa with 39.5% (95% CI 22.3–59.7) and a sample size of 2989 people with the age range 18–95 years. Conclusion According to the medical, economic, and social burden of osteoporosis, providing a robust and comprehensive estimate of the prevalence of osteoporosis in the world can facilitate decisions in health system planning and policymaking, including an overview of the current and outlook for the future; provide the necessary facilities for the treatment of people with osteoporosis; reduce the severe risks that lead to death by preventing fractures; and, finally, monitor the overall state of osteoporosis in the world. This study is the first to report a structured review and meta-analysis of the prevalence of osteoporosis worldwide.

AbstractObjectiveTo evaluate and quantify the future risk of cardiovascular events in young adults with high blood pressure.DesignSystematic review and meta-analysis.Data sourcesMedline, Embase, and Web of Science were searched from inception to 6 March 2020. Relative risks were pooled using a random effects model and expressed with 95% confidence intervals. Absolute risk difference was calculated. Dose-response relations between blood pressure and individual outcomes were assessed by a restricted cubic spline model.Eligibility criteria for selecting studiesStudies were selected that investigated the adverse outcomes of adults aged 18-45 with raised blood pressure. The primary study outcome was a composite of total cardiovascular events. Coronary heart disease, stroke, and all cause mortality were examined as secondary outcomes.ResultsSeventeen observational cohorts consisting of approximately 4.5 million young adults were included in the analysis. The average follow-up was 14.7 years. Young adults with normal blood pressure had increased risk of cardiovascular events compared with those with optimal blood pressure (relative risk 1.19, 95% confidence interval 1.08 to 1.31; risk difference 0.37, 95% confidence interval 0.16 to 0.61 per 1000 person years). A graded, progressive association was found between blood pressure categories and increased risk of cardiovascular events (high normal blood pressure: relative risk 1.35, 95% confidence interval 1.22 to 1.49; risk difference 0.69, 95% confidence interval 0.43 to 0.97 per 1000 person years; grade 1 hypertension: 1.92, 1.68 to 2.19; 1.81, 1.34 to 2.34; grade 2 hypertension: 3.15, 2.31 to 4.29; 4.24, 2.58 to 6.48). Similar results were observed for coronary heart disease and stroke. Generally, the population attributable fraction for cardiovascular events associated with raised blood pressure was 23.8% (95% confidence interval 17.9% to 28.8%). The number needed to treat for one year to prevent one cardiovascular event was estimated at 2672 (95% confidence interval 1639 to 6250) for participants with normal blood pressure, 1450 (1031 to 2326) for those with high normal blood pressure, 552 (427 to 746) for those with grade 1 hypertension, and 236 (154 to 388) for those with grade 2 hypertension.ConclusionsYoung adults with raised blood pressure might have a slightly increased risk of cardiovascular events in later life. Because the evidence for blood pressure lowering is limited, active interventions should be cautious and warrant further investigation.

Objective: It is still controversial whether differentiated thyroid carcinoma (DTC) in patients with Graves disease (GD) can be more aggressive than non-Graves DTC. We conducted a systematic review and meta-analysis to examine the association between GD and prognosis in patients with DTC. Methods: We comprehensively searched the databases of MEDLINE and EMBASE from inception to March 2019. We included published studies that compared the risk of mortality and prognosis between DTC patients with GD and those with non-GD. Data from each study were combined using the random-effects model. Results: Twenty-five studies from February 1988 to May 2018 were included (987 DTC patients with GD and 2,064 non-Graves DTC patients). The DTC patients with GD had a significantly higher risk of associated multifocality/multicentricity (odds ratio, 1.45; 95% confidence interval, 1.04 to 2.02; I 2, 6.5%; P = .381) and distant metastasis at the time of cancer diagnosis (odds ratio, 2.19; 95% confidence interval, 1.08 to 4.47; I 2, 0.0%; P = .497), but this was not associated with DTC-related mortality and recurrence/persistence during follow-up. Conclusion: Our meta-analysis demonstrates a statistically significant increased risk of multifocality/multicentricity and distant metastasis at the time of cancer diagnosis in DTC patients with GD than those without GD.

Objectives: Gallstone disease shares certain risk factors with cardiovascular disease, particularly metabolic risk factors. Patients with gallstone disease may be at increased risk of cardiovascular disease. Several recent studies exploring the effect of gallstone disease on cardiovascular disease outcomes demonstrated inconsistent results. Design: We conducted a systematic review and meta-analysis of cohort, case–control, and cross-sectional studies that compared the risk of developing cardiovascular disease events in patients with gallstone disease versus non-gallstone disease controls. Data from each study were combined using the random-effects, generic inverse variance method of DerSimonian and Laird to calculate the pooled hazard ratio, odd ratio, and 95% confidence interval. Results: Data were extracted from six studies involving 176,734 cases and 803,714 controls. The pooled hazard ratio of cardiovascular events in patients with gallstone disease was 1.28 (95% confidence interval: 1.23–1.33, I2 = 42%). The pooled odd ratio of cardiovascular events in patients with gallstone disease was 1.82 (95% confidence interval: 1.47–2.24, I2 = 68%). Conclusions: Our study demonstrated a statistically significant increase in the risk of cardiovascular disease among patients with gallstone disease.

Dupuytren Disease

Abstract Background The Dupuytren disease is a benign fibroproliferative disorder that leads to the formation of the collagen knots and fibres in the palmar fascia. The previous studies reveal different levels of Dupuytren’s prevalence worldwide; hence, this study uses meta-analysis to approximate the prevalence of Dupuytren globally. Methods In this study, systematic review and meta-analysis have been conducted on the previous studies focused on the prevalence of the Dupuytren disease. The search keywords were Prevalence, Prevalent, Epidemiology, Dupuytren Contracture, Dupuytren and Incidence. Subsequently, SID, MagIran, ScienceDirect, Embase, Scopus, PubMed and Web of Science databases and Google Scholar search engine were searched without a lower time limit and until June 2020. In order to analyse reliable studies, the stochastic effects model was used and the I2 index was applied to test the heterogeneity of the selected studies. Data analysis was performed within the Comprehensive Meta-Analysis Software version 2.0. Results By evaluating 85 studies (10 in Asia, 56 in Europe, 2 in Africa and 17 studies in America) with a total sample size of 6628506 individuals, the prevalence of Dupuytren disease in the world is found as 8.2% (95% CI 5.7–11.7%). The highest prevalence rate is reported in Africa with 17.2% (95% CI 13–22.3%). According to the subgroup analysis, in terms of underlying diseases, the highest prevalence was obtained in patients with type 1 diabetes with 34.1% (95% CI 25–44.6%). The results of meta-regression revealed a decreasing trend in the prevalence of Dupuytren disease by increasing the sample size and the research year (P < 0.05). Conclusion The results of this study show that the prevalence of Dupuytren disease is particularly higher in alcoholic patients with diabetes. Therefore, the officials of the World Health Organization should design measures for the prevention and treatment of this disease.

ObjectiveTo estimate the association between the use of sodium glucose co-transporter-2 (SGLT2) inhibitors and postmarket harms as identified by drug regulatory agencies.DesignWe conducted a systematic review and meta-analysis of randomised controlled trials (RCT). Six large databases were searched from inception to May 2018. Random effects models were used to estimate pooled relative risks (RRs).InterventionSGLT2 inhibitors, compared with placebo or active comparators.Primary outcomesAcute kidney injury (AKI), diabetic ketoacidosis (DKA), urinary tract infections (UTI), bone fractures and lower limb amputations.ResultsWe screened 2418 citations of which 109 were included. Most studies included one of four SGLT2 inhibitors, dapagliflozin, canagliflozin, empagliflozin and ipragliflozin. When compared with placebo, SGLT2 inhibitors were found to be significantly protective against AKI (RR=0.59; 95% CI 0.39 to 0.89; I2=0.0%), while no difference was found for DKA (RR 0.66; 95% CI 0.30 to 1.45, I2=0.0%), UTI (RR 1.02; 95% CI 0.95 to 1.09, I2=0.0%) or bone fracture (RR 0.87; 95% CI 0.69 to 1.09, I2=1.3%). Three studies reported on amputation, with one finding a significant increase risk. No increased risk for either outcome was found when compared with active controls. Subgroup analysis did show an increased risk of UTI with dapagliflozin only (RR 1.21; 95% CI 1.02 to 1.43, I2=0.0%), but no other analysis supported an increased risk of AKI, DKA, UTI or fracture.ConclusionsCurrent evidence from RCTs does not suggest an increased risk of harm with SGLT2 inhibitors as a class over placebo or active comparators with respect to AKI, DKA, UTI or fracture. However, wide CIs for many comparisons suggest limited precision, and therefore clinically important adverse events cannot be ruled out. Dapagliflozin, appears to independently increase the risk of UTI, although the mechanism for this intraclass variation in risk is unclear.PROSPERO registration numberCRD42016038715.

The Relationship

Background: Coffee is one of the drinks most often consumed throughout the world and is the second most popular beverage in the world after water. At present, the effect of coffee consumption on the human body is increasingly being studied, especially on the cardiovascular system. Many studies say that coffee consumption can prevent stroke, either directly or indirectly against stroke risk factors by a variety of mechanisms caused by the compounds contained in coffee. However, to date various prospective studies looking at the relationship between coffee consumption and stroke risk are still inconsistent. Objectives: To determine the relationship of coffee consumption with the risk of stroke. Methods: We searched on MEDLINE and PubMed, using the keywords “coffee” or “caffeine” and "stroke or cardiovascular events" which follows the flow and search rules of the Reporting Item Options for Systematic Review and Meta Analysis (PRISMA) to find studies with cohort design in the last 10 years starting in 2009-2019. Discussion: Among 226 citations identified in this systematic review, only 10 studies met the inclusion criteria. Four studies provided evidence that coffee consumption habits were not associated with an increased risk of stroke, while 6 other studies explaining that more coffee consumption has protective benefits against the risk of stroke. Conclusion: Coffee consumption shows a preventive effect on stroke risk. Keywords: caffeine, coffee, relative risk, stroke risk Latar Belakang: Kopi merupakan salah satu minuman yang paling sering dikonsumsi di seluruh dunia dan menjadi minuman populer kedua di dunia setelah air. Saat ini, pengaruh konsumsi kopi untuk tubuh manusia semakin banyak diteliti, khususnya terhadap sistem kardiovaskular. Banyak penelitian mengatakan bahwa konsumsi kopi dapat mencegah timbulnya penyakit stroke, baik secara langsung atau tidak langsung terhadap faktor risiko stroke dengan beragam mekanisme yang ditimbulkan oleh senyawa yang terkandung dalam kopi. Namun, hingga saat ini beragam studi prospektif yang mengamati hubungan antara konsumsi kopi dan risiko stroke masih belum konsisten. Tujuan: Untuk mengetahui hubungan konsumsi kopi dengan risiko terjadinya stroke. Metode: Pencarian dilakukan pada MEDLINE dan PubMed dengan menggunakan kata kunci “coffee or caffeine” and “stroke or cardiovascular events”. yang mengikuti alur dan kaidah pencarian Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) untuk mencari studi dengan desain cohort dalam rentang waktu 10 tahun terakhir mulai tahun 2009-2019. Pembahasan: Dari 226 sitasi yang teridentifikasi pada systematic review, hanya 10 studi yang sesuai dengan kriteria inklusi. Empat penelitian memberikan bukti bahwa kebiasaan mengonsumsi kopi tidak dikaitkan dengan peningkatan risiko stroke, sedangkan 6 penelitian lainnya, menjelaskan bahwa konsumsi kopi yang lebih banyak memiliki manfaat perlindungan terhadap risiko kejadian stroke. Kesimpulan: Konsumsi kopi menunjukkan efek pencegahan terhadap risiko stroke. Kata Kunci: kafein, kopi, risiko relatif, risiko stroke

Abstract Ibrutinib therapy was associated with an increased risk of bleeding in previous trials. In this systematic review and meta-analysis of published trials including patients treated with ibrutinib, the relative risk (95% confidence interval [CI]) of overall bleeding was significantly higher in ibrutinib recipients (2.72 [1.62-6.58]), but major bleeding did not show a significant difference (1.66 [0.96-2.85]). The incidences (95% CI) of major bleeding and any bleeding were 3.0 (2.3-3.7) and 20.8 (19.1-22.1) per 100 patient-years, respectively. This analysis is limited by reporting bias from variable ascertainment of bleeding and lack of allocation concealment in some studies and differing exposures between groups, leading to potential overestimation of event rates in the ibrutinib group.
