Increased risk of developing psychiatric disorders in children with attention deficit and hyperactivity disorder (ADHD) receiving sensory integration therapy: a population-based cohort study.

Parents of children with attention deficit hyperactivity disorder (ADHD) have been found to prefer sensory integration (SI) training rather than guideline-recommended ADHD treatment. This study investigated whether SI intervention for children with ADHD was associated with a reduced risk of subsequent mental disorders. From children < 8-years-old newly diagnosed with ADHD in a nationwide population-based dataset, we established a SI cohort and a non-SI cohort (N =  1945) matched by propensity score. Incidence and hazard ratios of subsequent psychiatric disorders were compared after a maximum follow-up of 9 years. The incidence of psychiatric disorders was 1.4-fold greater in the SI cohort, with an adjusted hazard ratio of 1.41 (95% confidence interval 1.20-1.67), comparing to the non-SI cohort. Risks were elevated for emotional disturbances, conduct disorders, and adjustment disorders independent of age, gender, or comorbidity. Among children with only psychosocial intervention, the incidence of psychiatric disorders was 3.5-fold greater in the SI cohort than in the non-SI cohort. To our knowledge, this is the first study to report an increased risk of developing psychiatric disorders for children with ADHD who received SI compared to those who did not. Potential adverse effects of SI for ADHD children should be carefully examined and discussed before practice.

Male, old age and low income to predispose epilepsy in migraineurs.

BACKGROUND: This study investigated whether sex, age, income and any comorbidity affect subsequent epilepsy development in migraineurs. MATERIALS AND METHODS: A total of 4915 men diagnosed with migraine who were aged older than 20 years were identified as the study cohort. A total of 4882 female migraineurs were included in the comparison cohort. We calculated the adjusted hazard ratio (aHR) for the risk of epilepsy in the two cohorts after adjustment for age and comorbidity. Kaplan-Meier analysis was used to analyse the cumulative epilepsy incidence, and the log-rank test was used to estimate the differences between the two cumulative incidence curves. RESULTS: The risk of epilepsy was 2·31-fold higher in male migraineurs than in female migraineurs. The income-specific analysis showed that the risk of epilepsy was high in migraineurs with a low monthly income [aHR: 2·73 for 15 000-25 000 new Taiwan dollar (NTD; approximately 500-833 USD) and aHR: 2·71 for < 15 000 NTD]. Among patients with one or more comorbidity, a 2·48-fold (95% confidence interval: 1·65-3·74) high risk of epilepsy was noted in male migraineurs, regardless of the presence of head injury. Additional analyses revealed that male migraineurs aged 65 years or older had the highest risk of epilepsy. CONCLUSION: Migraineurs have an increased risk of subsequent epilepsy. Male sex, old age and low income may interact with migraine and result in a high risk of epilepsy in migraineurs.

Incident asthma and Mycoplasma pneumoniae: A nationwide cohort study.

BACKGROUND: Previous studies investigating the relationship between Mycoplasma pneumoniae and incident asthma in the general population have been inconclusive. OBJECTIVE: We conducted a nationwide cohort study to clarify this relationship. METHODS: Using the National Health Insurance Research Database of Taiwan, we identified 1591 patients with M pneumoniae infection (International Classification of Diseases, Ninth Revision, Clinical Modification code 4830) given diagnoses between 2000 and 2008. We then frequency matched 6364 patients without M pneumoniae infection from the general population according to age, sex, and index year. Cox proportional hazards regression analysis was performed to determine the adjusted hazard ratio (aHR) of the occurrence of asthma in the M pneumoniae cohort compared with that in the non-M pneumoniae cohort. RESULTS: Regardless of comorbidities and the use of antibiotic or steroid therapies, patients with M pneumonia infection had a higher risk of incident asthma than those without it. The aHR of asthma was 3.35 (95% CI, 2.71-4.15) for the M pneumoniae cohort, with a significantly higher risk when patients were stratified by age, sex, follow-up time, and comorbidities, including allergic rhinitis, atopic dermatitis, or allergic conjunctivitis. Patients with M pneumoniae infection had a higher risk of having early-onset (age, <12 years; aHR, 2.87) and late-onset (age, ≥12 years; aHR, 3.95) asthma. The aHR was also higher within the less than 2-year follow-up in the M pneumoniae cohort (aHR, 4.41; 95% CI, 3.40-5.74) than in the cohort without the infection. CONCLUSION: This study found that incident cases of early-onset and late-onset asthma are closely related to M pneumoniae infection, even in nonatopic patients.

Men with nonapnea sleep disorders have a high risk of developing subsequent epilepsy: A nationwide population-based cohort study.

OBJECTIVE: This nationwide population-based cohort study evaluated the effects of nonapnea sleep disorders (NSDs) on the development of epilepsy. METHODS: We identified 63,865 patients aged ≥20years, diagnosed with NSDs (ICD-9-CM: 307.4 or 780.5), and without coding for apnea-related sleep disorders (ICD-9-CM: 780.51, 780.53, or 780.57) during 2000-2003 as the NSD cohort. In addition, we enrolled a comparison cohort of 127,728 patients. We calculated the adjusted hazard ratio (aHR) for developing epilepsy (ICD-9-CM: 345) after adjustment for age, sex, comorbidities, and drug use. A Kaplan-Meier analysis was used to measure the cumulative incidence of epilepsy between the 2 groups until the end of 2011. RESULTS: The cumulative incidence of epilepsy was significantly higher in the NSD cohort than in the comparison cohort. The aHR for developing epilepsy in the NSD cohort was 1.52 (95% CI=1.37-1.69). The risk of developing epilepsy was higher among males (aHR=1.41) than among females. The age-stratified effects of NSDs on developing epilepsy were the highest among patients aged ≥65years. When comorbidities and NSDs coexisted, the risk of epilepsy was specifically increased in patients having an NSD and stroke (aHR: 8.61, 95% CI: 7.43-9.98) in addition to brain tumors (aHR: 7.66, 95% CI: 5.06-11.6). CONCLUSION: This study indicated that patients with NSDs have a higher risk of developing epilepsy and that the risk is much higher among men and older patients. These findings suggest that NSDs constitute a predisposing, possibly independent factor for developing subsequent epilepsy in adulthood.

Increased risk of fracture in patients with bipolar disorder: a nationwide cohort study.

OBJECTIVES: Bipolar disorder (BD) is a systemic inflammatory disease, and disrupted bone metabolism due to the inflammatory process can cause fracture. Despite evidence of an association between lower bone mineral density and an increased risk of fracture among patients with depression, schizophrenia, and anorexia nervosa, whether BD is a risk factor for subsequent fracture is unknown. To determine the association between BD and fracture and to examine the risk factors for fracture among patients with BD. METHODS: In this study, we enrolled patients diagnosed with BD from the Taiwan National Health Insurance Research Database. Patients newly diagnosed with BD (ICD-9-CM 296) from 2001 to 2008 were included in the BD cohort, and the date of the initial diagnosis of BD was used as the index date. The comparison cohort, comprising participants without BD, was frequency matched to the BD cohort by age, sex, and index year, and the occurrence of fracture was evaluated in both cohorts. RESULTS: The BD and comparison cohorts were comprised of 47,271 patients with BD and 1,89,084 frequency-matched participants without BD, respectively. The incidence of fracture was higher among patients with BD than among the controls. Cox models showed that BD was an independent risk factor for fracture irrespective of comorbidities [hazard ratio (HR) = 1.79, 95 % confidence interval (CI) = 1.73-1.84, p < .001]. CONCLUSION: Our study showed that patients with BD have a higher risk of subsequent fracture. Additional prospective clinical studies investigating the relationship between BD and fracture are warranted.

Nontuberculosis mycobacterium disease is a risk factor for chronic obstructive pulmonary disease: a nationwide cohort study.

BACKGROUND: The aim of this study was to evaluate the association between chronic obstructive pulmonary disease (COPD) and nontuberculosis mycobacterium (NTM) disease. METHODS: We used data from the National Health Insurance Research Database of Taiwan in this study. The NTM cohort contained 3,005 patients, and each case was randomly frequency matched by age, sex, income, occupation, and index year with four people from the general population without NTM infections. Multivariate Cox proportional hazards regression was used to calculate adjusted hazard ratios (aHR) of COPD in the NTM cohort compared with the non-NTM cohort. RESULTS: The incidence of COPD was 3.08-fold higher (21.75 vs. 6.11 per 1,000 person-years) in the NTM cohort than in the non-NTM cohort. The aHR of COPD comparing the NTM cohort with the non-NTM cohort was 3.57 (95 % CI 2.56-4.97) for women and 2.89 (95 % CI 2.31-3.61) for men. The aHR of COPD was higher in the patients with NTM infection and a comorbidity such as bronchopneumonia, pneumonia, diabetes, asthma, and heart disease. The Mycobacterium avium-intracellulare complex group (MAC) and the non-MAC group were isolated in the NTM cohort. The MAC group had a higher aHR of COPD than the non-NTM cohort (aHR = 3.72, 95 % CI 2.94-4.72). The cumulative incidence of COPD in the NTM cohort was higher than in the non-NTM cohort (P < 0.0001, log rank test). CONCLUSIONS: Physicians should be aware of indolent NTM disease that increases the risk of COPD.

Secular Increasing Trends in Female Thyroid Cancer Incidence in Taiwan.

BACKGROUND: Thyroid cancer incidence has increased globally in recent decades, especially in females, although its trends in Taiwan have not been studied extensively. This study aimed to investigate changes in female incidence and possible causes of thyroid cancer in Taiwan. METHODS: Using the Taiwan Cancer Registry (TCR) Database, age-standardized incidence rates, age-specific incidence rates and birth cohorts were calculated. Correlation between female thyroid cancer incidence and cohort fertility rates were examined. RESULTS: Thyroid cancer incidence increased in Taiwanese female, with age-adjusted rates per 100,000 people increasing from 7.37 during 1995-1999 to 20.53 during 2015-2019; the annual percentage change (APC) was 5.9% (95% CI, 5.3-6.5). Age-specific incidence rates increased with age, with peak rates occurring at younger ages. The APCs in the 50-54 age group were the highest (6.8%, 95% CI, 6.1-7.5). Incidence rates also increased with later birth cohorts. We observed a significant negative correlation between thyroid cancer incidence and fertility rates in the same birth cohort. CONCLUSIONS: We hypothesize that overdiagnosis may be a main reason for the rapidly increasing thyroid cancer incidence in Taiwanese females. Notably, we observed a strong negative correlation between fertility and thyroid cancer incidence. However, our study is limited by the absence of individual-level cancer data in the TCR database. These associations with fertility will be an important subject for future thyroid cancer research.

High-Fat Diet Exacerbates Autistic-Like Restricted Repetitive Behaviors and Social Abnormalities in CC2D1A Conditional Knockout Mice.

Autism spectrum disorder (ASD) represents a heterogeneous group of neurodevelopmental disorders characterized by deficits in social communication, social interaction, and the presence of restricted repetitive behaviors. The cause of ASD involves complex interactions between genetic and environmental factors. Haploinsufficiency of the Coiled-coil and C2 domain containing 1A (Cc2d1a) gene is causally linked to ASD, and obesity has been associated with worse outcomes for ASD. High-fat diet (HFD) feeding leads to the development of obesity and metabolic dysfunction; however, the effect of HFD on pre-existing autistic-like phenotypes remains to be clarified. Here, we report that male Cc2d1a conditional knockout (cKO) mice fed with HFD, from weaning onwards and throughout the experimental period, show a marked aggravation in autistic-like phenotypes, manifested in increased restricted repetitive behaviors and impaired performance in the preference for social novelty, but not in sociability and cognitive impairments assessed using the object location memory, novel object recognition, and Morris water maze tests. HFD feeding also results in increased numbers of reactive microglia and astrocytes, and exacerbates reductions in dendritic complexity and spine density of hippocampal CA1 pyramidal neurons. Furthermore, we demonstrate that chronic treatment with minocycline, a semisynthetic tetracycline-derived antibiotic, rescues the observed behavioral and morphological deficits in Cc2d1a cKO mice fed with HFD. Collectively, these findings highlight an aggravating role of HFD in pre-existing autistic-like phenotypes and suggest that minocycline treatment can alleviate abnormal neuronal morphology and behavioral symptoms associated with ASD resulted from the interplay between genetic and environmental risk factors.

Enhancing anatomy education through cooperative learning: harnessing virtual reality for effective gross anatomy learning.

The advent of virtual reality (VR) in education offers unique possibilities for facilitating cooperative learning strategies, particularly in fields demanding intricate spatial understanding, such as gross anatomy. This study investigates the impact of integrating cooperative learning strategies within a VR-based gross anatomy curriculum, focusing on enhancing students' anatomy knowledge and skills. We analyzed the performance of two cohorts of first-year nursing students across five semesters (2016-2020), where traditional learning methods were used in the first three semesters (2016-2018), and a VR-based cooperative learning approach was adopted in the last two semesters (2019-2020). Our findings suggest that the VR-based cooperative learning group achieved significantly higher scores in their gross anatomy laboratory courses compared to their counterparts learning through traditional methods. This research provides valuable insights into how the integration of VR technology and cooperative learning strategies can not only enhance learning outcomes but also improve the VR learning experience by reducing motion sickness. It accentuates the potential of VR-based cooperative learning as an impactful educational tool in anatomy education. Future research should further explore the optimal integration of VR and cooperative learning strategies in diverse course types and their potential to enhance educational outcomes and the learning experience.

Risk Factors for Female Breast Cancer: A Population Cohort Study.

BACKGROUND: The incidence of female BC among the Eastern and Southeastern Asian populations has gradually increased in recent years. However, epidemiological studies on the relationship between a sedentary lifestyle and female BC are insufficient. In order to determine the association between this lifestyle and the incidence of female BC, we conducted a population-based cohort study on women in Taiwan. METHODS: We followed a prospective cohort of 5879 women aged 30 years and over enrolled in the 2001 National Health Interview Survey (NHIS), who developed female BC over a period of 72,453 person years, and we estimated the hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) using the Cox proportional hazards model. RESULTS: RFs associated with female BC incidence included parity (adjusted HR = 0.63; 95% CI: 0.44-0.91), body mass index (adjusted HR = 1.34; 95% CI: 1.04-1.71), and ≥3 h/day spent sitting (adjusted HR = 1.89; 95% CI: 1.08-3.32). The incidence of female BC in participants who sat for ≥3 h/day and consumed sugary drinks was 2.5 times greater than that in those who sat for <3 h/day and did not consume sugary drinks (adjusted HR = 2.51; 95% CI: 1.01-6.23). CONCLUSIONS: The findings of this study indicate that sedentary behavior and sugary drink intake may increase the risk of developing female BC. These are modifiable RFs; therefore, a healthy lifestyle and diet can reduce the incidence of female BC.

Metformin, Statin Use, and Female Colorectal Cancer: A Population-Based Cohort Study in Taiwan.

In the last few years, the incidence of colorectal cancer (CRC) in women has gradually increased. However, epidemiological studies on the relationship between type II diabetes mellitus (T2DM) and female CRC and the effect of metformin or statins on female CRC are insufficient. To determine their association, we conducted a population-based cohort study on women in Taiwan. We collected data on a total of 396,521 women aged 40 to 64 years old from 1 January 2007 to 31 December 2009 from the National Health Insurance Research Database. We followed up on all participants in the cohort until the occurrence of CRC, the date for all death, or 31 December 2015. Full development of CRC was identified using the International Classification of Disease (ICD), 9th Revision, code 153. We estimated hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) using the Cox proportional hazards model. Both metformin (adjusted hazard ratio, aHR = 1.12; 95% CI: 0.934-1.335, p = 0.227) and statin (aHR = 1.03; 95% CI: 0.906-1.172, p = 0.645) use showed no association with female CRC in a multivariate analysis. The findings indicate that metformin and statin use showed no protective effect against female colorectal cancer (CRC). An additional randomized trial is necessary to investigate the effect of metformin and statin use in CRC prevention.

Sedative and Immunosuppressive Effects of Dexmedetomidine in Transplantation.

Dexmedetomidine, an α2-adrenergic receptor agonist, is used as an anti-anxiety medication. It exerts a cholinergic effect, thereby reducing the release of tumor necrosis factor alpha (TNF-α). We hypothesized that the use of dexmedetomidine as a sedative agent in transplantation would also protect allografts. We examined our patients who underwent living donor liver transplantation. Subsequently, we generated a series of mouse models to investigate the effect of dexmedetomidine on sedation-based tolerance post transplantation. A total of 49 liver recipients were enrolled in this study, of which 23 (47%) were administered dexmedetomidine through 24 h infusion on postoperative day 1. A trend toward the improvement of hepatocyte injury along with better liver function was observed in the dexmedetomidine-treated group during the first postoperative week. In animal models, dexmedetomidine inhibited the proliferation of CD4+ and CD8+ T cells and TNF-α production in a dose-dependent manner. We used dexmedetomidine to treat skin-transplanted mice and observed a significantly prolonged graft survival in mice that were administered a higher dose of dexmedetomidine. Our results revealed that dexmedetomidine exerts a dual effect of sedation and immunosuppression. This light-sedation approach will not only make patients calmer in the intensive care unit but also protect allografts from injury.

The Decisive Case-Control Study Elaborates the Null Association between ESR1 XbaI and Osteoarthritis in Asians: A Case-Control Study and Meta-Analysis.

(1) Background: The prevalence of knee osteoarthritis (OA) in women is significantly higher than in men. The estrogen receptor α (ERα) has been considered to play a key role due to a large gender difference in its expression. ERα is encoded by the gene estrogen receptor 1 (ESR1), which is widely studied to explore the gender difference in knee OA. Several polymorphisms in ESR1 [PvuII (rs2234693) and BtgI (rs2228480)] were confirmed as the risk factors of OA. However, the evidence of the last widely investigated polymorphism, ESR1 Xbal (rs9340799), is still insufficient for concluding its effect on knee OA. (2) Objective: This study proposed a case-control study to investigate the association between ESR1 Xbal and knee OA. Moreover, a meta-analysis and trial sequential analysis (TSA) were conducted to enlarge the sample size for obtaining a conclusive evidence. (3) Methods: In total, 497 knee OA cases and 473 healthy controls were recruited between March 2015 and July 2018. The Kellgren-Lawrence grading system was used to identify the knee OA cases. To improve the evidence level of our study, we conducted a meta-analysis including the related studies published up until December 2018 from PubMed, Embase, and previous meta-analysis. The results are expressed as odds ratios (ORs) with corresponding 95% confidence intervals (CI) for evaluating the effect of this polymorphism on knee OA risk. TSA was used to estimate the sample sizes required in this issue. (4) Results: We found non-significant association between the G allele and knee OA [Crude-OR: 0.97 (95% CI: 0.78-1.20) and adjusted-OR: 0.90 (95% CI: 0.71-1.15) in allele model] in the present case-control study, and the analysis of other genetic models showed a similar trend. After including six published studies and our case-control studies, the current evidence with 3174 Asians showed the conclusively null association between ESR1 XbaI and knee OA [OR: 0.78 (95% CI: 0.59-1.04)] with a high heterogeneity (I2: 78%). The result of Caucasians also concluded the null association [OR: 1.05 (95% CI: 0.56-1.95), I2: 87%]. (5) Conclusions: The association between ESR1 XbaI and knee OA was not similar with other polymorphisms in ESR1, which is not a causal relationship. This study integrated all current evidence to elaborate this conclusion for suggesting no necessity of future studies.

Possible increased risk of colonic diverticular disease from alcohol intoxication or abuse.

Alcohol consumption has been suggested as a potential risk factor for diverticular diseases. This study investigated the association between alcohol intoxication or abuse and colonic diverticular disease (CDD).Using the National Health Insurance Research Database of Taiwan from January 1, 2000, to December 31, 2008, 51, 866 subjects newly diagnosed with alcohol intoxication were enrolled in this study as the alcohol intoxication cohort. The control (nonalcohol intoxication) cohort was frequency-matched 1:4 by age, sex and index year. Data were analyzed using a Cox proportional hazards model.The overall incidence of CDD (per 10,000 person-years) for the alcohol intoxication and control cohorts was 16.4 and 3.46, respectively. Compared with patients in the control cohort (95% confidence interval [CI] = 2.76-3.74), those with alcohol intoxication exhibited a 3.21-fold risk of CDD; the risk was particularly higher in male patients (adjusted hazard ratio [aHR] = 3.19, 95% CI = 2.72-3.74) and in those aged <45 years (aHR = 4.95, 95% CI = 3.91-6.27). The alcohol intoxication still had higher risk of CDD than nonalcohol intoxication, regardless of subjects without comorbidity (aHR = 3.38, 95% CI = 2.77-4.11) or with (aHR = 2.85, 95% CI = 2.25-3.61).There was a significant relationship between alcohol intoxication or abuse and CDD.

Increased Risk for Hip Fractures among Patients with Cholangitis: A Nationwide Population-Based Study.

BACKGROUND: Cholangitis is the infectious disease involving the biliary tract, which may induce systemic inflammation. Bone loss is a well-known sequelae after systemic inflammatory disease, and one grave complication after osteoporosis is hip fracture. We want to know whether cholangitis can contribute to increased risk of hip fracture. METHODS: All the patients diagnosed with cholangitis since January 1, 2001, to December 31, 2009, were assessed. All the subjects with cancer history, traumatic accident, and previous fracture were excluded. We selected the controls without cholangitis and matched the controls to cholangitis patients by age, sex, osteoporosis, and the use of steroid for more than 30 days by approximately 1:4 ratio. RESULTS: There were 2735 subjects in the cholangitis cohort and 10915 in the noncholangitis cohort. There were 101 hip fractures in the cholangitis cohort with the incidence density of 7.58 per 1000 person-years. As for the noncholangitis cohort, 366 individuals suffered from hip fracture with the incidence density of 5.86 per 1000 person-years. The risk of hip fracture was higher in the cholangitis cohort with a 1.29-fold increased risk than the noncholangitis cohort (hazard ratio = 1.29, 95% confidence interval = 1.03-1.61). The association between cholangitis and the hip fracture was more prominent among subjects less than 65 years (hazard ratio = 2.65, 95% confidence interval =1.30-5.39) and the subjects without comorbidities (hazard ratio = 3.01, 95% confidence interval = 1.42-6.41). CONCLUSIONS: Cholangitis is associated with higher risk for hip fracture, especially among young subjects free from medical comorbidities.

Association between use of short-acting benzodiazepines and migraine occurrence: a nationwide population-based case-control study.

AIM: To evaluate the association between using benzodiazepines (BZDs) with short- or long-acting durations and migraine occurrence. METHODS: The migraine group comprised 9616 subjects older than 20 years and newly diagnosed with migraine between 2005 and 2011, and the comparison group comprised 38,464 subjects without migraine. The BZDs used in the subjects were dichotomously defined as short-acting (half-life ≤24 h) and long-acting substances. A logistic regression model was used to calculate the odds ratio (OR) of migraine associated with BZD exposure and other diseases. RESULTS: The adjusted OR of migraine associated with BZD exposure was 1.73 (95% confidence interval [CI] = 1.63-1.84). Either exposure to a short-acting BZD alone or using it combining with a long-acting BZD had significant higher risks of migraine (adjusted OR = 1.69, 95% CI = 1.59-1.80; adjusted OR = 2.06, 95% CI = 1.91-2.24, respectively), whereas only long-acting BZD use was not associated with an increase of migraine. Meanwhile, sleep disorders, anxiety, and stroke were strongly associated with migraine (adjusted OR = 2.00, 1.91, and 1.57, respectively). CONCLUSIONS: We observed a significant increase of migraine occurrence in subjects using short-acting BZDs, either alone or in combination with long-acting ones.

High risk of developing subsequent epilepsy in patients with sleep-disordered breathing.

PURPOSE: Sleep-disordered breathing (SDB) is often associated with other medical disorders. Whether SDB interacts with other factors for developing subsequent epilepsy remains unclear. METHODS: This population-based cohort study was conducted using the National Health Insurance Research Database of Taiwan. Patients aged >20 years and diagnosed with SDB between 2000 and 2010 comprised the SDB cohort (n = 138,507), and their data were compared with those of the comparison cohort (n = 138,507). The adjusted hazard ratio (aHR) for epilepsy was calculated using a multivariate Cox proportional hazards model. RESULTS: The SDB cohort had an increased risk of epilepsy (aHR = 1.50, 95% confidence interval [CI] = 1.36-1.66). The sex-stratified analysis revealed a significant adjusted hazard ratio (aHR) for epilepsy with a 1.51-fold higher risk for female patients, and also a significantly 1.49-fold higher risk for male patients in the SDB cohort. Although epilepsy incidence increased with age in both cohorts, different age groups in the SDB cohort all had a significantly higher risk of developing epilepsy than comparison cohort. CONCLUSION: This population-based cohort study indicates that patients with SDB are at a high risk of developing subsequent epilepsy, in both sexes and all age groups.

Alcohol use disorder increases the risk of necrotizing fasciitis: A nationwide retrospective cohort study.

This nationwide retrospective cohort study determined the association between alcohol use disorder (AUD) and the risk of necrotizing fasciitis (NF).This study used health insurance claims data of 52,212 in-patients with AUD and 208,848 controls randomly frequency-matched by age and sex at a 1:4 ratio. The AUD cohort included patients newly diagnosed with AUD between January 1, 2000 and December 31, 2008. The NF event occurrence was observed until December 31, 2011. We used the Kaplan-Meier method to present the cumulative incidence curve and Cox proportional hazard models to depict the risk of NF in patients with AUD.The incidence of NF was 19.4 per 10,000 person-years in the AUD cohort, which was nearly 7.73-fold higher than that in the comparison cohort (2.54 per 10,000 person-years). After adjustment for age, sex, and comorbidities, the patients with AUD exhibited a 3.55-fold higher risk of NF than did the controls (hazard ratio [HR] = 3.55, 95% confidence interval [CI] = 3.00-4.20). Nevertheless, in the AUD groups without any comorbidity, patients with AUD exhibited a significant 15.2-fold higher risk of NF than did the comparison cohort (HR = 15.2, 95% CI = 10.9-21.3). Moreover, the adjusted HRs of NF risk with respect to the severity of AUD were 2.15 (95% CI = 1.76-2.62), 4.54 (95% CI = 3.67-5.62), and 10.7 (95% CI = 8.66-13.2) for mild, moderate, and severe AUD, respectively.This study indicated that AUD should be considered an independent and significant risk factor for NF.

Selective Serotonin Reuptake Inhibitors and Poststroke Epilepsy: A Population-Based Nationwide Study.

OBJECTIVE: To investigate the effects of selective serotonin reuptake inhibitors (SSRIs) on poststroke epilepsy in a population-based nationwide study. PATIENTS AND METHODS: The SSRI group included patients who received a stroke diagnosis from January 1, 2000, through December 31, 2009, and were prescribed SSRIs after stroke. The non-SSRI group enrolled patients with stroke who were not prescribed SSRIs from the Taiwan National Health Insurance Research Database and used propensity score matching based on the index year, duration time, sex, age, type of stroke, and duration of hospitalization. Cox proportional hazards models were used to estimate the risk of epilepsy between the SSRI and comparison groups. RESULTS: A total of 4688 patients with stroke (2344 in each of the SSRI and non-SSRI cohorts) were enrolled. The cumulative incidence of epilepsy in the SSRI group was significantly higher than that in the comparison group (log-rank P<.001). In the SSRI group, the risk of poststroke epilepsy increased 2.45-fold (95% CI, 1.69- to 3.57-fold) compared with that in the comparison group. Furthermore, the risk of poststroke epilepsy increased with the defined daily dose of SSRIs. For patients with ischemic stroke, SSRIs users had a 2.74-fold higher risk of epilepsy than non users (95% CI, 1.79- to 4.22-fold). CONCLUSION: In this study, SSRI users had a higher risk of poststroke epilepsy than nonusers. Further study is warranted to investigate the causal relationship between SSRI exposure and poststroke epilepsy.

Female schizophrenia patients and risk of breast cancer: A population-based cohort study.

OBJECTIVE: Breast cancer is the most common type of cancer in women. This population-based cohort study aimed to examine the association between breast cancer in female schizophrenia patients and its association with the use of antipsychotics drugs. METHODS: All study subjects were selected from the Taiwan Insurance Claims Data (1998-2008). We compared the risk for breast cancer between female schizophrenia patients receiving antipsychotics (n=29,641) with female patients without any serious mental illnesses nor receiving antipsychotic drugs (n=59,282). We also compared between patients on 1) first-generation antipsychotics (FGAs) alone; 2) combination of first and second generation antipsychotics (SGAs); and 3) SGAs alone. We then stratified those on SGAs into two subgroups according to their prolactin-elevating properties: risperidone (RIS), paliperidone (PAL) or amisulpride (AMI) and all other SGAs. RESULTS: After adjusting for confounding factors, the risk of breast cancer in female schizophrenia patients was 1.94 higher than the non-schizophrenia cohort (aHR: 1.94, 95% CI: 1.43-2.63). Schizophrenia patients receiving a combination of FGAs and SGAs had a slightly higher risk of breast cancer than non-schizophrenic patients (aHR: 2.17, 95% CI: 1.56-3.01). Patients on RIS, PAL, and AMI had a 1.96-fold risk of breast cancer compared to the non-schizophrenic cohort (95% CI: 1.36-2.82). CONCLUSIONS: This study raises awareness among both clinicians and patients about the importance of breast cancer screening and the promotion of healthy lifestyle choices. Due to the nature of our database, confounding factors - such as parity, obesity, hormone therapy, and smoking - could not be controlled for.
