RESUMO
This study aims to assess the association between nicotine replacement therapy (NRT), varenicline, and untreated smoking with the risk of developing eye disorders. We employed a new-user design to investigate the association between NRT use and the incidence of eye disorders by the Taiwan National Health Insurance program. This study included 8416 smokers who received NRT and 8416 smokers who did not receive NRT (control group) matched using propensity scores between 2007 and 2018. After adjustment for relevant factors, a multivariable Cox regression analysis revealed that compared with untreated smokers, NRT use was associated with a significantly reduced risk of macular degeneration (hazard ratio [HR]: 0.34; 95% confidence interval [CI]: 0.13-0.87, P = 0.024). When stratified by dose, short-term NRT use (8-28 defined daily doses) was associated with significantly lower risk of glaucoma (HR: 0.35; 95% CI: 0.16-0.80, P = 0.012) and a trend toward reduced risk of cataract (HR: 0.60; 95% CI: 0.36-1.01, P = 0.053) compared to no treatment. However, these associations were not observed with long-term NRT use. The results of this real-world observational study indicate that NRT use, particularly short-term use, was associated with a lower risk of certain eye disorders compared to no treatment for smoking cessation. Long-term NRT use did not demonstrate the same benefits. Thus, short-term NRT may be a beneficial treatment strategy for reducing the risk of eye disorders in smokers attempting to quit. However, further evidence is required to verify these findings and determine the optimal duration of NRT use.

We evaluated the long-term risks of overall cancer and all-cause mortality associated with five types of phytopharmaceuticals and the most commonly used estrogen-progestogen medications for the treatment of postmenopausal syndrome in women. Using data from Taiwan's National Health Insurance Research Database (NHIRD) from 1 January 2000 to 31 December 2018, we conducted a 1:2 matched cohort study with 12,087 eligible patients. We compared phytopharmaceuticals -only users (n = 4029, phytopharmaceuticals group) with HRT-only users (n = 8058, HRT group) with a washout period of ≥6 months. The phytopharmaceuticals group had significantly lower risks of overall cancer and all-cause mortality than the HRT group (adjusted hazard ratio [95% confidence interval]: 0.60 [0.40-0.9] and 0.40 [0.16-0.99], respectively) after over 180 days of use. Bupleurum and Peony Formula were associated with lower risks of overall cancer and all-cause mortality (aHR: 0.57 [0.36-0.92] and 0.33 [0.11-1.05], respectively). In conclusion, phytopharmaceuticals may serve as an alternative therapy to HRT for alleviating menopausal symptoms and reducing health risks, leading to more favorable long-term health outcomes. Further randomized control trials are necessary to validate the findings of this study.
RESUMO
N-Nitrosodimethylamine (NDMA), a carcinogenic chemical, has recently been identified in ranitidine. We conducted a population-based study to explore ranitidine use and cancer emergence over time. Using the Taiwan National Health Insurance Research Database, a population-based cohort study was conducted. A total of 55,110 eligible patients who received ranitidine between January 2000 and December 2018 were enrolled in the treated cohort. We conducted a 1:1 propensity-score-matching procedure to match the ranitidine-treated group with the ranitidine-untreated group and famotidine controls for a longitudinal study. The association of ranitidine exposure with cancer outcomes was assessed. A multivariable Cox regression analysis that compared cancer risk with the untreated groups revealed that ranitidine increased the risk of liver (hazard ratio (HR): 1.22, 95% confidence interval (CI): 1.09-1.36, p < 0.001), lung (HR: 1.17, CI: 1.05-1.31, p = 0.005), gastric (HR: 1.26, CI: 1.05-1.52, p = 0.012), and pancreatic cancers (HR 1.35, CI: 1.03-1.77, p = 0.030). Our real-world observational study strongly supports the pathogenic role of NDMA contamination, given that long-term ranitidine use is associated with a higher likelihood of liver cancer development in ranitidine users compared with the control groups of non-ranitidine users treated with famotidine or proton-pump inhibitors.

BACKGROUND: The postoperative bleeding complications associated with laser surgery of the prostate and transurethral resection of the prostate (TURP) were compared. METHODS: We used the Taiwan National Health Insurance Research Database to conduct an observational population-based cohort study. All eligible patients who received transurethral procedures between January 2015 and September 2018 were enrolled. Patients who received laser surgery or TURP were matched at a ratio of 1:1 by using propensity score matching, and the association of these procedures with bleeding events was evaluated. RESULTS: A total of 3302 patients who underwent elective transurethral procedures were included. The multivariable Cox regression analysis revealed that diode laser enucleation of the prostate (DiLEP) resulted in significantly higher emergency room risks within 90 days after surgery due to clot retention than the Monopolar transurethral resection of the prostate (M-TURP) (Hazard Ratio: 1.52; 95% Confidence Interval [CI], 1.06-2.16, p = 0.022). Moreover, GreenLight photovaporization of the prostate (PVP) (0.61; 95% CI, 0.38-1.00 p = 0.050) and thulium laser vaporesection of the prostate (ThuVARP) (0.67; 95% CI, 0.47-0.95, p = 0.024) resulted in significantly fewer rehospitalization due to clot retention than did M-TURP. No significant increase in blood clots were observed in patients using comedications and those with different demographic characteristics and comorbidities. CONCLUSIONS: Among the investigated six transurethral procedures for Benign prostatic hyperplasia, PVP and ThuVARP were safer than M-TURP because bleeding events and clot retention were less likely to occur, even in patients receiving anticoagulant or antiplatelet therapy. However, DiLEP and holmium laser enucleation of the prostate (HoLEP) did not result in fewer bleeding events than M-TURP.
RESUMO
Postmenopausal women with hepatitis B virus (HBV) infection are more likely to have accelerated liver fibrosis, eventually advancing to liver cirrhosis or hepatocellular carcinoma (HCC). The association between sex hormones and HBV-related HCC risk is unclear. We investigated whether hormone replacement therapy (HRT) is beneficial to postmenopausal women with HBV infection. This retrospective study selected the data of 44,465patients with HBV infection between January 2000 and December 2018 from Taiwan's National Health Insurance Research Database. After excluding patients with preexisting liver diseases, liver cirrhosis, or liver malignancies, we grouped the remaining 10,474 patients by whether they had undergone HRT for at least 3 months (n = 5,638) and whether they had not received HRT (n = 4,836). After propensity score matching, we assigned 3080 patients to an HRT cohort and matched them (1:1) with those in a non-HRT cohort. The incidence of HCC (P < 0.022) and all-cause mortality rate (P < 0.001) were lower in the HRT cohort than in the non-HRT cohort. The liver cirrhosis risk was not significantly higher in the HRT cohort (P = 0.355). HRT is associated with reduced HCC risk and improved survival outcomes but is unrelated to liver cirrhosis development in postmenopausal women.

Diabetes mellitus (DM) was found to be more common in hepatitis C virus (HCV)-related cirrhotic males. However, the association between DM, or other extrahepatic manifestations (EHMs), and liver cirrhosis is still undetermined. We used a large-scale long-term study to analyze the cirrhosis risk of treatment-naïve HCV patients with EHMs as compared to those without. In this retrospective nested case-control study, we identified 11 872 treatment-naïve patients with chronic HCV between 2001 and 2013 from Taiwan National Health Insurance Research Database and divided them into patients with (cases) and without cirrhosis (controls). All patients were followed up from the index month (exact month of diagnosis) to the end of 2013, death, or study outcome, whichever occurred first. The cases and controls were 1:6 propensity score matched for age, sex, and exact month of diagnosis; finally, 8078 patients (1154 with and 6924 without cirrhosis) were included in the analysis. The presence of coexisting EHMs and a new diagnosis of cirrhosis was analyzed. Adjusted hazard ratios (HRs) and cumulative incidence for cirrhosis were calculated in conditional Cox regression models after propensity score matching. Patients with high-cirrhosis-risk EHMs, such as DM (HR: 1.72, 95% CI: 1.51-1.96, P < .001), HCD (HR: 1.45, 95% CI: 1.27-1.67, P < .007), CKD (HR: 1.21, 95% CI: 1.05-1.38, P < .001), hyperlipidemia (HR: 0.53, 95% CI: 0.46-0.60, P < .001), lichen planus (HR: 2.71, 95% CI: 1.56-4.72, P < .001), and palpable purpura (HR: 2.67, 95% CI: 2.13-3.35, P < .001) exhibited significantly higher risk of liver cirrhosis than those without. Cumulative incidence (P < .001) of liver cirrhosis by pairwise comparisons of multiple high-cirrhosis-risk EHMs, and that of lichen planus was the highest. Our study provided direct estimates of specific HCV-associated EHM time trends of cirrhosis risk, with an upward trend in incidence. Lichen planus was at the top of the list of single-EHM comparisons, and the maximum combination of certain EHMs was the greatest risk factor across a different array of multi-EHM comparisons for liver cirrhosis development.

There has been no clear consensus on the optimal consolidation periods following HBeAg seroconversion (SC) in HBeAg-positive chronic hepatitis B (CHB) patients. Our study aimed to prospectively compare relapse rates between 12 months' and 18 months' consolidation periods to see whether or not there is beneficial durability of tenofovir disoproxil fumarate (TDF) therapy with longer consolidation periods.We enrolled a total of 137 HBeAg-positive Asian CHB patients treated with TDF monotherapy. Forty-six patients achieved HBeAg SC. Then, they were randomly assigned to consolidation period of either 12 months (group A) or 18 months (group B). After stopping TDF therapy, all patients were followed up for 12 months.Thirteen patients (56.5%) relapsed in group A and 12 patients (52.2%) relapsed in group B after 12 months' follow-up (Pâ=â.958). Pretreatment HBsAg level is the only significant predictor for off-therapy recurrence by univariate analysis (Pâ=â.024). Baseline HBeAg >1000âS/CO in group B patients were significantly less likely to relapse than those of group A (Pâ=â.046). Baseline alanine aminotransferase (ALT) >133âU/L could significantly predict occurrence of HBeAg SC (Pâ=â.008; 95% CI: 0.545-0.763; AUC: 0.654).Overall, a prolonged consolidation period has no positive effect on TDF therapy on sustained viral suppression in HBeAg-positive Asian CHB patients. However, a prolonged consolidation period was beneficial to patients with high baseline semi-quantitative HBeAg levels in terms of off-treatment durability. Baseline ALTâ>â133âU/L could significantly predict the occurrence of HBeAg SC.

BACKGROUND: The rate of preterm birth has been increasing worldwide. Most preterm babies are at an increased risk of central nervous system impairments as well as respiratory and gastrointestinal complications. The aim of this study was to investigate the epidemiologic characteristics of and associated factors contributing to preterm birth in Taiwan. METHODS: Information on obstetric antecedents and risk factors for preterm birth in pregnant women was obtained from the National Health Insurance Research (NHIR) database provided by the Taiwan National Health Research Institute. All live births from 2004 to 2013 in Taiwan were included in this study. RESULTS: A total of 130,362 live births from 2004 to 2013 were included in this study. Overall, the average annual rate of preterm births increased by 5.3% (from 3.33% in 2004 to 5.11% in 2013). Multiple logistic regression analyses showed that nulliparous women, multifetal pregnancies, advanced mother age, history of preterm birth, history of maternal drug abuse/dependence, and maternal medical complications were positively associated with an increased risk of preterm birth (all p-values< 0.05). CONCLUSION: The overall proportion of preterm births increased from 2004 to 2013 in Taiwan. Babies born preterm had a higher risk of developing morbidities and mortalities. The development of a comprehensive program to identify the high-risk group is needed for effective interventions to prevent premature birth.

Background: The work of homecare nurses is different from that of general hospital nurses; therefore, it is necessary to understand the risks of occupational diseases in homecare nurses. Materials and Methods: In this retrospective cohort research conducted from 2000 to 2013, nursing staff comprised the sample obtained from the National Health Insurance Research Database. Nursing staff were subgrouped according to practice site into homecare, medical center, regional hospital, and local community hospital nurses. The control group included 4,108 subjects. Results: The risk of severe kidney disease was higher in homecare nurses than in medical center nurses (hazard ratio [HR]: 7.3, 95% confidence interval [CI]: 2.45-21.78) and regional hospital nurses (HR: 3.30, 95% CI: 1.37-7.96). The risk of severe liver disease was higher in homecare nurses than in medical center nurses (HR: 1.92, 95% CI: 1.10-3.35) and regional hospital nurses (HR: 2.06, 95% CI: 1.17-3.62). Conclusions: The prevalence of occupational diseases was higher in homecare nurses than in noncaregivers. The correlation between different practice environments and disease prevalence rates revealed that various types of nurses can be ranked in the following order based on the prevalence of the aforementioned diseases: homecare nurses > local community hospital nurses > regional hospital nurses > medical center nurses.
RESUMO
This retrospective cohort study evaluated the effects of different frequencies of physical therapy intervention on the total knee arthroplasty (TKA) and total hip arthroplasty (THA) risk of osteoarthritis (OA) patients.We sampled 438,833 insurants from Taiwan National Health Insurance Research Database for patients diagnosed as having OA during 2000 to 2013. OA who received physical therapy within in the first year of OA diagnosis were divided based on the number of sessions they received in that first year: >24, 13-23, and <12 sessions.The results revealed that the TKA and THA incidence rates among patients aged 60 to 80 years were respectively 3.5% and 0.9% in the >24 cohort and 4.9% and 1.4% (all Pâ<â.001) in the comparison cohort. Moreover, the HRs of TKA and THA in the >24 cohort were 0.77 (0.67-0.87, Pâ<â.001) and 0.71 (0.53-0.96, P = .024), respectively. By contrast, no significant differences were noted between the 13-23 and <12 cohorts and their respective comparison cohorts.In conclusion, our study results indicated that elderly patients aged 60 to 80 years who underwent >24 physical therapy sessions within 1 year of receiving an OA diagnosis exhibited reduced of TKA and THA risks.

BACKGROUND: This study aimed to investigate the occurrence and risk factors of thyroid dysfunction (TD) in patients with chronic hepatitis C (CHC) infection in Taiwan. METHODS: The data in this study were obtained from the Taiwan National Health Insurance Research (Taiwan NHIR) database between 2001 and 2013. CHC patients treated with pegylated interferon/ribavirin (PEG-IFN/RBV) were enrolled as case patients, and nontreated CHC patients were enrolled as controls and were matched at a control:case ratio of 3:1 by index date, age (± 3 years), and sex. We compared the cumulative incidence of TD between the cohorts at follow-up until 2013. RESULTS: During the study period, 3810 cases and 9393 controls were included in the study. Among the study subjects, 173 (4.5%) case patients and 244 (2.6%) controls were diagnosed with TD during the follow-up period. The types of TD were hypothyroidism (42.9%), hyperthyroidism (31.2%), and thyroiditis (25.9%). Compared to controls during the 13-year follow-up, patients treated with PEG-IFN/RBV had a higher incidence rate of TD (P < 0.0001), as determined using the Kaplan-Meier method. Cox proportional hazards regression analysis showed that female sex (adjusted hazard ratio (HR): 1.49; 95% confidence interval (CI): 1.23-1.75; P < 0.001), treatment with PEG-IFN/RBV (HR: 1.68; 95% CI: 1.38-2.06; P < 0.001), hyperlipidemia (HR: 1.38; 95% CI: 1.12-1.71; P < 0.001), and past history of goiter (HR: 6.40; 95% CI: 5.00-8.18; P < 0.001) were independent predictors for the development of TD. CONCLUSIONS: PEG-IFN/RBV treatment may be an independent risk factor for thyroid dysfunction among patients with hepatitis C virus (HCV) infection. Monitoring thyroid function keenly during PEG-IFN/RBV therapy in patients with chronic HCV infection is recommended for clinicians, especially for female patients and for patients with a history of hyperlipidemia and goiter.

The aim of this study was to quantitatively estimate the long-term risk of abortion-related consequences and comorbidities.We identified 36,375 patients with at least 2 diagnosed abortions from 2000 to 2013 and included them in the abortion group. This group was further subdivided into 4 subgroups: spontaneous abortion, induced abortion, nonspecific abortion, and mixed-type abortion groups. For comparison, another 36,375 pregnant women from the National Health Insurance Research Database of Taiwan were included in the nonabortion group. For the puerperal cohort, the index year was defined as the year with the occurrence of at least 1 pregnancy. The puerperal cohort was then matched to the abortion cohort by age; comorbidities of diabetes mellitus, hypertension, and hyperlipidemia; and index year at a 1:1 ratio. The data of these cohorts were used to examine the risk of abortion-related consequences and comorbidities in pregnant women after a mean follow-up period of 7.60 person-years.The spontaneous abortion group exhibited significantly elevated adjusted hazard ratios (HRs) of 1.493 for pelvic inflammatory disease (Pâ<â.001), 1.680 for urinary tract infection (Pâ<â.001), 3.771 for ectopic pregnancy (Pâ<â.001), and 1.938 for infertility with no subsequent conception (Pâ<â.001). However, this group exhibited statistically insignificant HRs of 1.709 for placenta previa (Pâ=â.260), 2.982 for placenta abruption (Pâ=â.344), 1.499 for incompetent cervix (Pâ=â.658), and 0.854 for early onset of labor (Pâ=â.624). The induced abortion group showed a statistically significant elevated adjusted HR of 1.291 for urinary tract infection (Pâ=â.008) but statistically insignificant HRs of 1.031 for pelvic inflammatory disease, 1.637 for ectopic pregnancy, 5.114 for placenta previa, 65.434 for placenta abruption, 0.998 for incompetent cervix, 0.285 for early onset of labor, and 1.019 for subsequent infertility with no subsequent conception.Clinicians encountering patients in a predicament such as spontaneous or induced abortion should unprejudicely and objectively inform the patients of the effects or influence of abortion on their physical health, including statistically significant and insignificant risks. Induced abortion may not be an independent risk factor for subsequent infertility.
