Depression risk in chronic tonsillitis patients underwent tonsillectomy: a global federated health network analysis.

Background: Tonsillectomy is a common surgery in the US, with possible postoperative complications. While small studies indicate postoperative depressive symptoms may occur, large-scale evidence is lacking on the tonsillectomy-depression link. Methods: We conducted a retrospective cohort study using the TriNetX US collaborative network, offering de-identified electronic health data from 59 collaborative healthcare organizations (HCOs) in the United States. In this study, people being diagnosed of chronic tonsillitis between January 2005 and December 2017 were enrolled. Patients deceased, with previous record of cancers or psychiatric events before index date were excluded. 14,874 chronic tonsillitis patients undergoing tonsillectomy were propensity score matched 1:1 to controls for age, sex, and race. New-onset depression risks were evaluated over 5 years post-tonsillectomy and stratified by age and sex. Confounders were adjusted for including demographics, medications, comorbidities and socioeconomic statuses. Results: After matching, the difference of key baseline characteristics including age, sex, comedications status and obesity status was insignificant between tonsillectomy and non-tonsillectomy groups. Tonsillectomy had a 1.29 times higher 5-year depression risk versus matched controls (95% CI, 1.19-1.40), with elevated risks seen at 1 year (HR=1.51; 95% CI, 1.28-1.79) and 3 years (HR=1.30; 95% CI, 1.18-1.43). By stratifications, risks were increased for both males (HR=1.30; 95% CI, 1.08-1.57) and females (HR=1.30; 95% CI, 1.18-1.42), and significantly higher in ages 18-64 years (HR=1.37; 1.26-1.49), but no significance observed for those 65 years and older. After performing sensitivity analyses and applying washout periods of 6, 12, and 36 months, the outcome remained consistent with unadjusted results. Conclusion: This real-world analysis found tonsillectomy was associated with a 30% higher 5-year depression risk versus matched non-tonsillectomy patients with chronic tonsillitis. Further mechanistic research is needed to clarify the pathophysiologic association between depression and tonsillectomy. Depression is not commonly mentioned in the current post-tonsillectomy care realm; however, the outcome of our study emphasized the possibility of these suffering condition after operation. Attention to psychological impacts following tonsillectomy is warranted to support patient well-being, leading to better management of post-tonsillectomy individuals.

Comparative Effectiveness of Varenicline and Nicotine Replacement Therapy for Smoking Cessation in Older and Younger Smokers: A Prospective Cohort in Taiwan.

Introduction: The effectiveness of varenicline compared with nicotine replacement therapy (NRT) in achieving smoking cessation in older smokers has not been investigated. This study prospectively compared the effectiveness of varenicline relative to NRT in smokers aged 25-54 years and separately in smokers aged 55 years or older. Methods: Among 13 397 smokers participating in the Smoking Cessation Program in Taiwan, 2012-2015, 6336 (19.2%, aged ≥55) received varenicline and 7061 received NRT patch or gum (23.2%, aged ≥55). Participants self-reported smoking behaviors by phone interview after 6 months. Logistic regression models estimated odds ratios (ORs) and 95% confidence intervals (CIs) for 7-day, 1-month, and 6-month point-prevalence abstinence. Age-specific models adjusted for sex, education, marital status, smoke-years, nicotine dependence, medical institution, clinic visit number, and duration of medication received. Results: Among smokers aged 25-54 years, varenicline users had a greater point-prevalence abstinence than NRT users (e.g., 7-day point-prevalence: 34.0% vs. 23.5%), with adjusted OR ranging from 1.23 (CI: 1.09-1.39; 6-month point-prevalence) to 1.37 (CI: 1.24-1.50; 1-month point-prevalence). Among smokers aged 55 years or older, point-prevalence was similar for varenicline and NRT users (e.g., 7-day point-prevalence: 32.3% vs. 33.1%), and ORs did not suggest that varenicline has greater effectiveness than NRT. Sex and level of nicotine dependence did not modify the age-specific effectiveness of varenicline relative to NRT. Conclusions: Varenicline did not offer greater effectiveness in achieving abstinence than NRT for smokers 55 years or older, whereas it was more effective than NRT in smokers aged 25-54 years. These findings highlighted the need for age-specific approaches for effective tobacco control. Implications: In this prospective investigation of a national cohort, older smokers (aged ≥55 years) who received varenicline did not have a greater point-prevalence abstinence after 6 months compared with those who used NRT patch or gum. Younger smokers (aged 25-54 years) who received varenicline had a greater likelihood of abstinence than NRT users. Sex and nicotine dependence did not modify the age-specific effectiveness of varenicline relative to NRT patch or gum. Age-appropriate approaches for effective tobacco control are needed.

Duration-response association between exercise and HDL in both male and female Taiwanese adults aged 40 years and above.

BACKGROUND: Exercise is an important cardiovascular risk reducing therapy. OBJECTIVE: The aim of this study was to assess the relationship between weekly exercise duration and high-density lipoprotein cholesterol (HDL-c) in Taiwanese men and women. METHODS: Data were retrieved from the dataset of the national adult preventive medical services which is recorded under the Health Promotion Administration (HPA). The lipid profiles of 194528 eligible participants aged 40 years and above who completed a questionnaire on recent health behavior including smoking, drinking, exercise and other factors in 2014 were determined. Weekly exercise durations of 0.0, <2.5 and ≥2.5 hours were classified as no, below recommended and recommended, respectively. The relationship between exercise and HDL-c was determined using linear regression. RESULTS: After multivariate adjustments, a duration-response association existed between exercise and HDL-c (P-trend <0.0001) in both sexes. Weekly exercise durations of <2.5 and ≥2.5 hours were both positively associated with HDL-c (P <0.0001) in both sexes. However, the associations were stronger in males than females in both exercise groups. Smoking (P <0.05) and BMI (P <0.0001) were negatively associated while drinking was positively associated with HDL-c in both sexes. CONCLUSION: This study demonstrated a duration-response association between exercise and HDL-c. Exercise at durations below the minimum weekly recommendation of 2.5 hours was positively associated with HDL-c.

Elucidating challenges that electronic cigarettes pose to tobacco control in Asia: a population-based national survey in Taiwan.

OBJECTIVES: This study investigated the prevalence and correlates of electronic cigarettes (e-cigarettes) use in Taiwan. DESIGN AND SETTING: We studied a nationally representative random sample in the 2015 Taiwan Adult Smoking Behavior Survey. PARTICIPANTS: This study included 26 021 participants aged 15 years or older (51% women, 79% non-smokers, 16% aged 15-24 years), after excluding 31 persons (0.1%) who had missing information on e-cigarette use. PRIMARY OUTCOME MEASURES: The prevalence of ever having used e-cigarettes was calculated in the overall sample and by smoking status (current, former and never) or age (15-24, 25-44 and ≥45 years). We performed multivariable log-binomial regression to assess correlates of ever having used e-cigarettes among all participants and separately for subgroups by smoking status and age. RESULTS: Approximately 3% of all participants had ever used e-cigarettes. The prevalence of ever having used e-cigarettes was high in current smokers (14%) and people aged 18-24 years (7%). E-cigarette use was particularly common in people aged 15-24 years who were current (49-52%) or former (22-39%) smokers. Ever having used e-cigarettes was positively associated with tobacco smoking (adjusted prevalence ratio (aPR): 21.5, 95% CI 15.4 to 29.8, current smokers; aPR: 8.3, 95% CI 15.2 to 13.1, former smokers), younger age and high socioeconomic status. Age remained a significant factor of ever having used e-cigarettes across smoking status groups. Among non-smokers, men had a 2.4-fold (95% CI 1.5 to 3.8) greater prevalence of e-cigarette use than women. CONCLUSIONS: E-cigarette use was uncommon in the general population in Taiwan, but prevalence was high among smokers and young people. This study highlights challenges that e-cigarettes pose to tobacco control, which warrant high priority action by policymakers and public health professionals. E-cigarette regulations should focus on young people.

Deep Dermatophytosis Caused by Zoophilic Strain of Trichophyton interdigitale with Successful Treatment of Itraconazole.

We report a 66-year-old female patient with deep dermatophytosis caused by zoophilic strain of Trichophyton interdigitale, a rare granulomatous presentation of Trichophyton species infection in patients with underlying systemic diseases, and she was successfully cured by itraconazole. Since the identification of Trichophyton mentagrophytes complex had been misused for years, a brief discussion of molecular diagnosis and taxonomy of T. mentagrophytes complex is given. The pathogenesis and comparison with cases reported in the literature are also discussed.

Comparative Effectiveness of Smoking Cessation Medications: A National Prospective Cohort From Taiwan.

BACKGROUND AND OBJECTIVE: Relative effectiveness of smoking cessation medications-varenicline, bupropion and nicotine replacement therapy (NRT)-remains unclear among smokers in real-world settings. Evidence in females and smokers with light/moderate nicotine dependence is particularly insufficient. This study compared the effectiveness of varenicline, bupropion or NRT gum relative to NRT patch, in achieving abstinence among recent quitters. METHODS: In a national smoking cessation program in Taiwan (2012-2015), a cohort of 11,968 participants received varenicline (n = 5,052), bupropion (n = 823), NRT gum (n = 1944) or NRT patch (n = 4,149). The 7-day, 1-month or 6-month point-prevalence was calculated based on self-reported last smoking event via telephone interview after 6 months. Logistic regression modellings estimated odds ratios (OR) and 95% confidence intervals (CI) for achieving abstinence using different modalities (NRT patch as referent). Models included age, sex, education, marital status, geographic region, smoke-years, nicotine-dependence level, medical institution, number of clinic visits and medication use duration. Analyses were further stratified by sex and dependence severity. RESULTS: Participants were predominantly male (83%) with a mean age of 43.7±12.6 years. Varenicline users were more likely than NRT patch users to achieve abstinence, based on 7-day point-prevalence (OR = 1.30, CI: 1.19-1.44), 1-month point-prevalence (OR = 1.36, CI: 1.24-1.50) or 6-month point-prevalence (OR = 1.30, CI: 1.14-1.47). Compared with NRT patch, varenicline was associated with greater odds of being abstinent in women (OR = 1.29, CI: 1.01-1.65), men (OR = 1.31, CI: 1.18-1.46), those with light/moderate dependence (OR = 1.42, CI: 1.24-1.63) or smokers with severe dependence (OR = 1.19, CI: 1.04-1.37), based on 7-day point-prevalence. Differences in effectiveness were not observed between users of bupropion, NRT gum and NRT patch. CONCLUSIONS: In smoking cessation clinics in Taiwan, varenicline users reported higher abstinence rates than NRT patch users after 6 months. Women and smokers with light/moderate nicotine dependence may also benefit from varenicline in actual clinical practice.

Risk of autistic disorder after exposure to general anaesthesia and surgery: a nationwide, retrospective matched cohort study.

BACKGROUND: Deficits of learning, memory and cognition have been observed in newborn animals exposed to general anaesthetics. However, conclusions from clinical studies conducted in humans to investigate the relationship between anaesthesia and neurodevelopmental disorders have been inconsistent. Autistic disorder is typically recognised earlier than other neurobehavioural disorders. Although certain genes apparently contribute to autistic disorder susceptibility, other factors such as perinatal insults and exposure to neurotoxic agents may play a crucial role in gene-environmental interaction. OBJECTIVE: This study was designed to investigate the association of exposure to general anaesthesia/surgery with autistic disorder. We hypothesised that exposure to general anaesthesia and surgery before 2 years of age is associated with an increased risk of developing autistic disorder. DESIGN: A retrospective matched-cohort study. SETTING: A medical university. Data from the National Health Insurance Research Database of Taiwan from 2001 to 2010 were analysed. PATIENTS: The birth cohort included 114,435 children, among whom 5197 were exposed to general anaesthesia and surgery before the age of 2 years. The 1 : 4 matched controls comprised 20,788 children. MAIN OUTCOME MEASURES: The primary endpoint was the diagnosis of autistic disorder after the first exposure to general anaesthesia and surgery. RESULTS: No differences were found in the incidence of autistic disorder between the exposed group (0.96%) and the unexposed controls (0.89%) (P = 0.62). Cox proportional regression showed that the hazard ratio of exposure to general anaesthesia and surgery was 0.93 [95% confidence interval (95% CI) 0.57 to 1.53] after adjusting for potential confounders. Age at first exposure did not influence the risk of autistic disorder. No relationship was found between the total number of exposures and the risk of autistic disorder. CONCLUSION: Exposure to general anaesthesia and surgery before the age of 2 years age at first exposure and number of exposures were not associated with the development of autistic disorder.

Risk factors for nonunion in 337 displaced midshaft clavicular fractures treated with Knowles pin fixation.

BACKGROUND: Clavicular fractures account for nearly 10 % of all fractures, and the majority of those fractures involve the midshaft. Historically, these fractures were treated nonoperatively; however, recent data suggest an increased risk of nonunion and symptomatic malunion for displaced, comminuted midshaft clavicular fractures treated conservatively. Surgical intervention via plate osteosynthesis or intramedullary fixation with pins, nails, or screws has been shown to reduce, but not eliminate, this risk. Identification of risk factors predictive of nonunion would improve the overall management of displaced, comminuted midshaft clavicular fractures. METHODS: The medical records of 337 consecutive patients who underwent Knowles pin fixation and supplemental cerclage for the treatment of displaced, comminuted midshaft clavicular fractures between April 2007 and March 2009 were retrospectively reviewed. The records of the mechanism of injury, side of injury, Robinson fracture classification, presence of associated injuries, cerclage material, and patient-related variables, including diabetes mellitus, hypertension and smoking, were analyzed. Variables were assessed by univariate and multivariate analysis to identify those factors significantly associated with the development of fracture nonunion. RESULTS: A total of 19 nonunions occurred. Increasing age and use of wire for supplemental cerclage fixation were significantly associated with an increased risk for fracture nonunion (p < 0.001). Although suggested as predictors of nonunion in other studies, female gender and fracture severity were not significantly associated with nonunion. CONCLUSIONS: Nonunion remains a significant complication in the treatment of displaced, comminuted midshaft clavicular fractures even with intramedullary fixation. Use of absorbable suture in place of wire for cerclage fixation and careful selection of treatment strategy in the elderly may reduce the risk for nonunion.

Treatment of interstitial cystitis with hydrodistention and bladder training.

This study aimed to evaluate the efficacy of hydrodistention (HD) and bladder training for interstitial cystitis (IC). From 1997 to 2006, 361 consecutive IC patients were treated by HD, followed by bladder training. Each patient was followed up using a diary for 8 weeks after HD weekly and monthly thereafter. The efficacy of the treatment was evaluated using the average of the voided volumes and the voiding frequency. The mean +/- standard deviation of the pre-HD daytime voided volumes and voiding frequency were 110.0 +/- 47.0 ml and 14.7 +/- 11.0, respectively. Furthermore, the nocturnal values were 173.1 +/- 91.8 ml and 2.8 +/- 1.7, respectively. After 72 weeks post-HD, the 185 patients who completed the follow-up had volumes/frequency of daytime, 306.5 +/- 80 ml and 6.9 +/- 2.1, respectively, and nocturnal, 325.8 +/- 122.4 ml and 1.3 +/- 0.6, respectively. The implementation of HD and bladder training is crucially important for long-term remission among IC patients.
