Abstract Objectives To explore the short- and long-term effects of glycemic management—through glycemic treatment and blood glucose monitoring (BGM)—on stroke recurrence and mortality specifically in patients experiencing a first-ever ischemic stroke (FIS) with hyperglycemia (FISHG) who have not previously been diagnosed with diabetes mellitus (DM). Methods We gathered data on patients who were registered on Taiwan’s National Health Insurance Research Database from 2000 to 2015. We one-fold propensity-score-matched (by sex, age, and index date) 207,054 patients into 3 cohorts: those with FIS (1) without hyperglycemia, (2) hyperglycemia without glycemic treatment, and (3) hyperglycemia with glycemic treatment. We used Cox proportional hazard regression to evaluate the short- (within 1 year after FIS) and long-term (9.3 ± 8.6 years after FIS) prognostic effects of glycemic management on stroke recurrence and mortality of FISHG. Results Stroke recurrence and mortality were significantly more likely in the patients with FISHG than their counterparts without hyperglycemia (p 0.05). Integrating BGM with glycemic treatment in the FISHG cohort significantly reduced the risk of stroke recurrence compared to patients receiving only glycemic treatment at 1-month, 3-month, 6-month, and 1-year post-stroke follow-ups (adjusted hazard ratios = 0.84, 0.90, 0.88, and 0.92, respectively); additionally, this approach significantly decreased mortality risk at each post-stroke follow-up period (p

Abstract Infectious intestinal diseases (IIDs) pose a significant health and economic burden worldwide. Recent observations at the Tri-Service General Hospital, Taiwan, suggest a potential association between IIDs and neurodegenerative diseases, prompting an investigation into this relationship. This study explored interactions between IIDs and neurodegenerative diseases. We conducted a population-based retrospective cohort analysis using data from the National Health Insurance Research Database (NHIRD) of Taiwan. Patients diagnosed with IIDs between 2000 and 2015 were identified along with a matched control group. Covariates, including demographics, comorbidities, and healthcare utilization were considered. The hazard ratios (HRs) of neurodegenerative diseases were assessed using a Cox proportional regression analysis. This study included 297,438 patients: 99,146 and 198,292 patients in the IID and control groups, respectively. Patients with IIDs showed a significantly higher overall risk of neurodegenerative diseases (adjusted hazard ratio [aHR] = 1.144, P

Background Pandemic influenza virus is a public health issue, and the neuraminidase inhibitors (NIs) “Oseltamivir” and “Zanamivir” are effective treatments. While teenagers use NIs, there are concerns regarding neuropsychiatric adverse events (NPAEs). Aim We aimed to use the Taiwan National Health Insurance Research Database to identify the correlation between NPAEs and NIs use in teenagers aged 13–19 years. Methods The final population between 2000 and 2015 included in this study was 3698 individuals, with 2287 individuals having received “Oseltamivir” and “Zanamivir” (study cohort group) and 9148 individuals not receiving “Oseltamivir” and “Zanamivir” (comparison cohort group). We initially used a multivariate Cox regression analysis during the tracking period to determine the cumulative incidence of NPAEs. Results Our findings revealed no significant increase in the likelihood of developing NPAEs in the study group. The Kaplan–Meier survival curve demonstrated that individuals who received “Oseltamivir” and “Zanamivir” were not associated with statistically significantly increased NPAEs compared with controls (log-rank test, P = 0.724). Conclusion No more risk in comparison of the normal population in our study, and the safety of “Oseltamivir” and “Zanamivir” is established treatments for influenza.

BACKGROUND AND OBJECTIVES: To study longitudinal associations between blood-based neural biomarkers (including total tau, neurofilament light [NfL], glial fibrillary acidic protein [GFAP], and ubiquitin C-terminal hydrolase-L1) and white matter neuroimaging biomarkers in collegiate athletes with sport-related concussion (SRC) from 24 hours postinjury to 1 week after return to play. METHODS: We analyzed clinical and imaging data of concussed collegiate athletes in the Concussion Assessment, Research, and Education (CARE) Consortium. The CARE participants completed same-day clinical assessments, blood draws, and diffusion tensor imaging (DTI) at 3 time points: 24-48 hours postinjury, point of becoming asymptomatic, and 7 days after return to play. DTI probabilistic tractography was performed for each participant at each time point to render 27 participant-specific major white matter tracts. The microstructural organization of these tracts was characterized by 4 DTI metrics. Mixed-effects models with random intercepts were applied to test whether white matter microstructural abnormalities are associated with the blood-based biomarkers at the same time point. An interaction model was used to test whether the association varies across time points. A lagged model was used to test whether early blood-based biomarkers predict later microstructural changes. RESULTS: Data from 77 collegiate athletes were included in the following analyses. Among the 4 blood-based biomarkers, total tau had significant associations with the DTI metrics across the 3 time points. In particular, high tau level was associated with high radial diffusivity (RD) in the right corticospinal tract (β = 0.25, SE = 0.07, p FDR-adjusted = 0.016) and superior thalamic radiation (β = 0.21, SE = 0.07, p FDR-adjusted = 0.042). NfL and GFAP had time-dependent associations with the DTI metrics. NfL showed significant associations only at the asymptomatic time point (|β|s > 0.12, SEs 0.14, SEs

BackgroundEctopic pregnancy (EP) occurs when a fertilized ovum is implanted outside the uterine cavity. Its incidence is 2% of all pregnancies and is known to decrease fertility. This study aimed to measure pregnancy rates after EP, identify the various parameters influencing pregnancy, and compare these variables in women with and without a history of EP, as well as determine in which medical facilities women with EP seek medical help.MethodsThe data was extracted from the National Health Insurance Research Database during 2000–2013. The study group included of women with a history of one EP (study group) and women without EP (control group). The chi-square/Fisher exact test was performed for categorical variables, and t-tests were used for continuous variables.ResultsThe EP group had a higher cumulative pregnancy rate (41.55%) than the control group (37.14 %), and a 1.16 times higher rate in developing pregnancy (p < 0.001). While the pregnancy rate in the EP group was initially lower than in the control group during the first 5 years, it surpassed the control group’s rate between the 10th and 14th years.ConclusionsFecundability after EP was lower at the beginning but increased at long-term follow-up.

BackgroundDementia poses a growing global mental health impact, with variations in prevalence by gender, possibly influenced by reproductive factors. Ectopic pregnancy (EP), known for its association with cardiovascular diseases and depression, which are also predictors of dementia, prompted an exploration of their interplay.MethodsUsing Taiwan’s National Health Insurance Research Database, this nationwide cohort study examined 53,096 individuals to investigate the link between EP and dementia. Covariates included age, insured premiums, comorbidity by Charlson Comorbidity Index revised by excluding dementia, level of care, and residence. Surgical approaches, number of EP episodes, and dementia subtypes were considered in outcomes analysis using Cox regression.ResultsAmong 13,274 women diagnosed with EP, 791 developed dementia over a 15-year follow-up, particularly vascular dementia. Adjusting for the covariates, the adjusted sub-distribution Hazard Ratio (asHR) with competing risks was 1.644 (95% CI, 1.394–2.053; p < 0.001). For patients with more than one episode, it was even higher (asHR=1.670 [95% CI, 1.419–2.092; p < 0.001]). Post-ectopic depression, prevalent in 62.2% within four weeks, was associated with a greater dementia risk compared to those without (asHR=1.702 [95% CI, 1.444-2.125; p

Sport-related concussion (SRC) is an important public health issue. White-matter alterations after SRC are widely studied by neuroimaging approaches, such as diffusion magnetic resonance imaging (MRI). Although the exact anatomical location of the alterations may differ, significant white-matter alterations are commonly observed in long fiber tracts, but are never proven. In the present study, we performed streamline tractography to characterize the association between tract length and white-matter microstructural alterations after SRC. Sixty-eight collegiate athletes diagnosed with acute concussion (24-48 h post-injury) and 64 matched contact-sport controls were included in this study. The athletes underwent diffusion tensor imaging (DTI) in 3.0 T MRI scanners across three study sites. DTI metrics were used for tract-based spatial statistics to map white-matter regions-of-interest (ROIs) with significant group differences. Whole-brain white-mater streamline tractography was performed to extract affected white-matter streamlines (i.e., streamlines passing through the identified ROIs). In the concussed athletes, streamline counts and DTI metrics of the affected white-matter fiber tracts were summarized and compared with unaffected white-matter tracts across tract length in the same participant. The affected white-matter tracts had a high streamline count at length of 80-100 mm and high length-adjusted affected ratio for streamline length longer than 80 mm. DTI mean diffusivity was higher in the affected streamlines longer than 100 mm with significant associations with the Brief Symptom Inventory score. Our findings suggest that long fibers in the brains of collegiate athletes are more vulnerable to acute SRC with higher mean diffusivity and a higher affected ratio compared with the whole distribution.

Abstract Background Hearing loss has been shown to be a risk factor for psychiatric disorders. In addition, long-term hearing loss is associated with increased hospitalization and mortality rates; however, the increased risk and duration of effect of hearing loss in combination with other chronic diseases on each psychiatric disorder are still not clearly defined. The purpose of this article is to clarify the risk of hearing loss for each disorder over time. Methods This was a retrospective cohort study, and a national health insurance research database in Taiwan was utilized. All (n = 1,949,101) Taiwanese residents who had a medical visit between 2000 and 2015 were included. Patients with hearing loss and a comparative retrospective cohort were analyzed. Every subject was tracked individually from their index date to identify the subjects who later received a diagnosis of a psychiatric disorder. The Kaplan‒Meier method was used to analyze the cumulative incidence of psychiatric disorders. Cox regression analysis was performed to identify the risk of psychiatric disorders. Results A total of 13,341 (15.42%) and 31,250 (9.03%) patients with and without hearing loss, respectively, were diagnosed with psychiatric disorders (P

Background/Objectives: According to the 2023 Ministry of Health and Welfare statistics, the suicide rate among adolescents aged 15 to 24 has steadily increased since 2018, from 3.7 to 5.5 per 100,000 populations, reaching a recent high. Although previous studies have pointed out that the future risk of suicide of those who had suffered from abuse was higher than that of the general population, researchers seldom focused on adolescent groups. Therefore, the aim of this study was to explore the risk of suicide after youth violence and the impact of subsequent comorbid mental illness and suicide risk. Methods: This retrospective matched cohort study analyzed data from the NHIRD, covering the period from 2000 to 2015. A total of 976 cases aged 10–18 who had experienced violence were included in this study. Controlled grouping was conducted by 1:10 matching based on gender, age, and the time of medical treatment, and a control group who had not experienced violence was selected for comparison. We used the Cox proportional hazards model to analyze the risk of suicide among adolescents after exposure to violence. Results: The suicide rate among adolescents who have experienced violence was significantly higher than that of the control group after 15 years of follow-up (1.0% vs. 0.5%). The prevalence of mental illness or disorders in adolescents exposed to violence was significantly higher than in the control group (45.2% vs. 40.1%). Among adolescents who had experienced violence, the methods of suicide included poisoning (solid and liquid) (53.6% vs. 43.2%), hanging (1.2% vs. 0.6%), firearms (2.4% vs. 0%), and cutting instruments (27.4% vs. 22.8%), all of which were significantly higher than in the control group. After adjusting for gender, age, residential area, and mental health comorbidities, the risk of suicide in those who had experienced violence was 1.475 times that of the control group (95% CI = 1.125–1.933; p = 0.005). Conclusions: In this study, female, younger age, and comorbid mental disorders were identified as risk factors for suicide among the adolescent victims of violence. Exposure to youth violence was associated with an increased prevalence of emotional disorders, including depression and social isolation, which subsequently elevated the suicide risk. These findings underscore the urgent need for governmental attention to the mental health of adolescent victims of violence. Implementing targeted psychological support and intervention programs could play a crucial role in mitigating the risk of suicide among this vulnerable population.

Objectives To evaluate whether nephrotic syndrome (NS) and further corticosteroid (CS) use increase the risk of osteoporosis in Asian population during the period January 2000–December 2010.Design Nationwide population-based retrospective cohort study.Setting All healthcare facilities in Taiwan.Participants A total of 28 772 individuals were enrolled.Interventions 26 614 individuals with newly diagnosed NS between 2000 and 2010 were identified and included in out study. 26 614 individuals with no NS diagnosis prior to the index date were age matched as controls. Diagnosis of osteoporosis prior to the diagnosis of NS or the same index date was identified, age, sex and NS-associated comorbidities were adjusted.Primary outcome measure To identify risk differences in developing osteoporosis among patients with a medical history of NS.Results After adjusting for covariates, osteoporosis risk was found to be 3.279 times greater in the NS cohort than in the non-NS cohort, when measured over 11 years after NS diagnosis. Stratification revealed that age older than 18 years, congestive heart failure, hyperlipidaemia, chronic kidney disease, liver cirrhosis and NS-related disease including diabetes mellitus, hepatitis B infection, hepatitis C infection, lymphoma and hypothyroidism, increased the risk of osteoporosis in the NS cohort, compared with the non-NS cohort. Additionally, osteoporosis risk was significantly higher in NS patients with CS use (adjusted HR (aHR)=3.397). The risk of osteoporosis in NS patients was positively associated with risk of hip and vertebral fracture (aHR=2.130 and 2.268, respectively). A significant association exists between NS and subsequent risk for osteoporosis.Conclusion NS patients, particularly those treated with CS, should be evaluated for subsequent risk of osteoporosis.
