Is Obesity a Risk or Protective Factor for Open-Angle Glaucoma in Adults? A Two-Database, Asian, Matched-Cohort Study. J Clin Med 2021; 10:jcm10174021. [PMID: 34501469 PMCID: PMC8432455 DOI: 10.3390/jcm10174021] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Revised: 08/28/2021] [Accepted: 09/02/2021] [Indexed: 11/17/2022] Open
Abstract
Obesity contributes to multiple systemic disorders; however, extensive discussion regarding obesity and open-angle glaucoma (OAG) remains limited, and conclusions in the existing literature diverge. This study aims to analyze the risk of OAG among obese adults in Taiwan. In this study, adults (aged ≥18 years) with a diagnostic code of obesity or morbid obesity registered in the Longitudinal Health Insurance Database (LHID) 2000 and LHID2005 from 1 January 2001 to 31 December 2010 were included. All adults were traced until the diagnosis of OAG, the occurrence of death, or 31 December 2013. Risk of OAG was significantly higher in obese adults than in non-obese adults after multivariable adjustment (adjusted hazard ratio (aHR): 1.43 (95% confidence interval (CI) 1.11-1.84)/aHR: 1.54 (95% CI 1.23-1.94) in the LHID2000/LHID2005). Both databases demonstrated that young obese adults (aged ≤40 years) had a remarkably increased risk of OAG compared with young non-obese adults (aHR 3.08 (95% CI 1.82-5.21)/aHR 3.81 (95% CI 2.26-6.42) in the LHID2000/LHID2005). This two-database matched-cohort study suggests that obese adults have an increased risk of OAG. In young adults, in particular, obesity could be a potential risk factor of OAG.

Abstract
PURPOSE This study assessed the benefits and efficacy of bariatric surgery (BS) in reducing the risk of cancer in Asians with morbid obesity. METHODS Records for patients aged between 18 and 55 years whose diagnoses corresponded with the ICD-9 codes for obesity and BS were extracted from the National Health Insurance Research Database (NHIRD) in Taiwan between 2000 and 2015. The patients who underwent BS (BS group), those who did not undergo BS (NS group), and the general population (GP group) were propensity score matched. The outcome was newly diagnosed malignancy. Data were extracted from the Registry for Catastrophic Illness Patient Database (RCIPD) of the NHIRD. RESULTS The BS group developed significantly less malignancy (1.18%) than the GP group (1.46%, p = 0.0364). There was no statistically significant difference in malignancy risk between the BS and GP groups (aHR =1.00, p = 0.9997). The NS group developed significantly higher malignancy (2.48%) than the GP group (1.97%, p < 0.0001). There was a significantly higher malignancy risk in the NS group (aHR =1.22, p < 0.0001) than in the GP group. In the subgroup analysis, the malignancy risks of the NS group were significantly higher in the subgroup of men aged between 18 and 35 years (aHR =1.37, p = 0.003) and women aged between 18 and 35 years (aHR = 1.62, p < 0.0001), and 35-55 years (aHR = 1.27, p < 0.0001). All the subgroup analyses between the BS and GP groups demonstrated no significant differences. CONCLUSIONS Our study demonstrated that BS reduced the risk of malignancy in patients with morbid obesity, particularly in women and young men.

Obes Surg 2021; 31:2231-2240. [PMID: 33604869 DOI: 10.1007/s11695-021-05262-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2020] [Revised: 01/21/2021] [Accepted: 01/26/2021] [Indexed: 12/20/2022]
Abstract
OBJECTIVES The aim of this study is to investigate the impact of bariatric surgery on non-traffic accident-related fractures in patients with obesity. METHODS This retrospective cohort study was conducted using the Taiwan National Health Insurance Research Database. Patients aged 18 to 55 years with obesity diagnosis between 2003 and 2008 were enrolled and divided into two groups: non-surgical and bariatric surgery groups. Patients with endocrine bone disease and malignancy history were excluded. Healthy patients were also randomly selected from the database and assigned to the general population group. The development of fracture was the primary end point. All patients were followed until the end of 2013 or death, whichever came first. RESULTS After propensity score matching, 1322, 1322, and 4359 subjects were included in the bariatric surgery (BS), non-surgical (NS), and general population (GP) groups, respectively. Based on multivariate analysis, the risk of overall fractures is similar between the BS group (hazard ratio [HR] = 0.774, p = 0.164) and the NS group; nevertheless, the risk of overall fractures was higher in the BS group (HR = 2.210, p<0.001) than in the GP group. The BS group had a significantly lower risk of non-traffic accident-related fractures (HR = 0.542, p = 0.010) than the NS group but a higher risk of non-traffic accident-related fractures (HR = 1.693, p = 0.023) than the GP group. CONCLUSIONS Bariatric surgery may decrease the risk of non-traffic accident-related fractures; however, the risk remains higher in patients with obesity than in the general population.

Abstract
PURPOSE This study aims to determine whether bariatric surgery (BS) decreases the risk of respiratory tract infections (RTIs) in obese patients. MATERIALS AND METHODS This retrospective, population-based, matched cohort study utilized data from the Taiwan National Health Insurance Research Database. All patients 18 to 55 years of age with obesity diagnosed between 2005 and 2010 were enrolled. Patients were separated into two groups based on whether they underwent BS. Two groups were selected using 1:1 propensity score matching according to age, sex, and comorbidities. The general population was also enrolled for comparison. The primary endpoint was the incidence of RTIs, including pneumonia, influenza, and bronchitis. All patients were followed up until the end of 2013, the primary endpoint, or death. RESULTS Compared to the non-surgery group, the BS group was at significantly lower risk for RTIs (aHR 0.432, 95% CI 0.340-0.549, p < 0.001) with shorter length of hospital stay (LOH) and lower cost. Regardless of the RTI-related mortality, pneumonia, influenza, and bronchitis rates, BS did have significant protective effects on the non-surgery group. Compared to the general population, the BS group was at higher risk for RTIs (aHR 3.601, 95% CI 2.742-4.728, p < 0.001) with similar LOH and lower cost. CONCLUSION Patients with obesity who underwent BS were at significantly lower risk for RTIs than obese patients who did not undergo BS but were at higher risk for RTIs than the general population. BS may result in a long-term reduction of the RTI risk.

The Increasing Possibility of Pregnancy Postbariatric Surgery: a Comprehensive National Cohort Study in Asian Population. Obes Surg 2020; 31:1022-1029. [PMID: 33188494 DOI: 10.1007/s11695-020-05099-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 10/27/2020] [Accepted: 10/29/2020] [Indexed: 12/15/2022]
Abstract
PURPOSE The present study aimed to investigate bariatric surgery's effects on pregnancy in obese women. MATERIALS AND METHODS The source of the data was the Taiwan National Health Insurance Research Database. We extracted female patients aged 18 to 45 years who had been diagnosed with obesity from 2005 to 2010. Two groups were formed based on bariatric surgery, according to the medical procedure codes of ICD-9-2001. The propensity score match of 1:1 was coordinated, based on the age, previous delivery, and the existence of comorbidities in patients. The primary endpoint was regarded as a pregnancy, including abortion, ectopic pregnancy, and delivery. The follow-up was performed until the end of 2013, or death. RESULTS There were 689 patients placed in each group, with a median of 64.8 follow-up months. Following multivariate analysis of the data, bariatric surgery resulted in significantly higher chances for pregnancy (aHR 2.886, p < 0.001) and resulted in a higher chance of successful delivery (aHR 2.775, p < 0.001) and vaginal delivery (aHR = 6.426, p < 0.001) compared with NS group. Moreover, we identified BS has a significantly higher proportion of vaginal delivery (BS 44.74% vs. NS 20%, p = 0.025) with significantly lower overall complications during labor (BS 9.21% vs. NS 33.3%, p = 0.006). CONCLUSION Patients suffering from obesity who undergo bariatric surgery have higher chances of pregnancy, successful delivery, vaginal delivery, and lower maternal complications during labor. Bariatric surgery did increase the possibility of pregnancy in obese patients.

Abstract
PURPOSE This study evaluated the differences in long-term cardiovascular events between obese patients who received bariatric surgery (BS), those who did not, and the general population (GP). METHODS Between 2003 and 2008, patients with severe obesity, aged 18-55 years, were divided into the non-surgical (NS) and BS groups and were included in this retrospective study. We also extracted data of healthy civilians defined as the GP. The incidence of cardiovascular events, including myocardial infarction, intracranial hemorrhage, epidural hemorrhage, ischemic stroke, and transient ischemic attack, was defined as the primary end point. Patients were followed up either until the end of 2013, upon reaching the primary end point, or death. RESULTS After propensity score matching, 1436 patients were included in both the BS and NS groups, and 4829 subjects were enrolled as the GP. Of these, 57 (3.9%), 10 (0.6%), and 30 (0.62%) subjects in the NS, BS, and GP, respectively, experienced cardiovascular events. Multivariate analysis revealed that patients with BS had a significantly lower risk of cardiovascular events (HR = 0.168; 95% CI 0.085-0.328; p < 0.001) than those in the NS group, but it was not significantly different in the BS group compared with the GP (HR = 1.202; 95% CI 0.585-2.471; p = 0.617). CONCLUSION Long-term risk of cardiovascular events was significantly lower among patients who had BS, compared to the NS obese patients. Thus, the long-term cardiovascular risk between those who received BS and the GP had no significant difference, in a retrospective view.
