Increased risk of benign paroxysmal positional vertigo in patients with anxiety disorders: a nationwide population-based retrospective cohort study.

BACKGROUND: The objective of this study was to evaluate the risk of benign peripheral persistent vertigo (BPPV) among patients with anxiety disorders by using the Taiwan National Health Insurance Research Database (NHIRD). METHODS: We conducted a retrospective study of 15,470 participants (7735 anxiety disorder patients and 7735 control patients) selected from the NHIRD. Patients were observed for a maximum of 9 years to determine the rates of newly diagnosed BPPV. A Cox regression model was used to evaluate the risk of BPPV among the patients with anxiety disorders. RESULTS: During the 9-year follow-up period, 178 (2.05 per 1000 person-years) anxiety disorder patients and 71 (0.81 per 1000 person-years) control patients were diagnosed with BPPV. The incidence risk ratio of BPPV between anxiety disorder patients and control patients was 2.52 (95 % confidence interval [CI], 1.90-3.37, P < .001). After adjustment for age, sex, and comorbidities, patients with anxiety disorders were found to be 2.17 times more likely to develop BPPV (95 % CI, 1.63-2.90, P < .001) than the control patients. Furthermore, female sex (HR = 1.81, 95 % CI, 1.31-2.50, P < .001) and cerebrovascular disease (HR = 1.53, 95 % CI, 1.00-2.34, P = .050) were independent risk factors for developing new-onset BPPV in patients with anxiety disorders. CONCLUSIONS: Anxiety disorder patients may have an increased risk of developing BPPV, especially those who are female or have cerebrovascular disease.

Prevalence and risk factors of asymptomatic colorectal diverticulosis in Taiwan.

BACKGROUND: To investigate the prevalence and risk factors of asymptomatic colorectal diverticulosis in Taiwanese general population. METHODS: From January 2009 to December 2011, consecutive asymptomatic subjects undergoing a health check-up were evaluated by colonoscopy. The colorectal diverticulosis was assessed, and a medical history and demographic data were obtained from each subject. Logistic regression analysis was conducted to search the risk factors of colorectal diverticulosis. RESULTS: Of the 1899 asymptomatic subjects, the prevalence of colorectal diverticulosis was 13.5%. On univariate logistic regression analysis, age over 60 years old, male, adenomatous polyp, current smoking and heavy alcohol consumption were significantly associated with diverticulosis. Multivariate logistic regression analysis revealed that age over 60 years old (relative risk [RR], 2.57; 95% confidence interval [CI], 1.64-6.47), adenomatous polyps (RR, 2.18; 95% CI, 1.18-4.61) and heavy alcohol consumption (RR, 1.82; 95% CI, 1.04-3.08) were independent predictors for colorectal diverticulosis. CONCLUSIONS: The prevalence of asymptomatic colorectal diverticulosis was 13.5% in Taiwan. Age over 60 years old, adenomatous polyp and heavy alcohol consumption may affect the risk of development of the disease.

Erosive esophagitis in asymptomatic subjects: risk factors.

INTRODUCTION: Asymptomatic erosive esophagitis is a common yet rarely reported disease. The purpose of this study is to investigate the prevalence of asymptomatic erosive esophagitis and to identify the risk factors for this disease. MATERIALS AND METHODS: In this study, we investigated 572 asymptomatic subjects undergoing health check-ups after upper gastrointestinal endoscopy. The severity of esophagitis was evaluated by the Los Angeles classification, and the independent risk factors for asymptomatic esophagitis were analyzed by the logistic regression method. RESULTS: The results showed the prevalence of erosive esophagitis in asymptomatic subjects was 12% (70/572). In all asymptomatic subjects, erosive esophagitis was grade A (71%) or B (29%). Univariate analysis revealed that male gender, high body mass index (BMI), and consumption of tobacco, alcohol, tea, spicy foods, and betel nut were associated with the development of erosive esophagitis. Multivariate analysis revealed that male gender (OR, 3.8, 95% CI, 1.5-9.3) and high BMI (BMI 25-30: OR, 2.3, 95% CI, 1.3-4.2; BMI >30: OR, 3.8, 95% CI, 1.3-10.9) were independent predictors of erosive esophagitis. CONCLUSION: Our data revealed male gender and high BMI are independent risk factors for asymptomatic erosive esophagitis.

Chronic fatigue of the small enterprise workers participating in an occupational health checkup center in southern Taiwan.

PURPOSE: There has been increasing interest in the occupational health of workers in small enterprises, especially in developing countries. This study examines the association between psychosocial job characteristics and fatigue, and attempts to identify risk factors for fatigue among workers of small enterprises in southern Taiwan. METHODS: A structured questionnaire was administered to workers receiving regular health examinations between August 2005 and January 2006. The questionnaire collected demographic information and data on working conditions, personal health status and life styles. It also collected information on psychosocial job characteristics, fatigue and psychological distress using three instruments. RESULTS: A total of 647 workers with mean age of 43.7 were completed. Probable fatigue was found in 34.6% of the sample. Fatigue was found by multiple logistic regressions to be associated with the lack of exercise, working in shifts, depression score and lack of social support at workplace. CONCLUSIONS: This study found associations between life style, psychosocial job characteristics and fatigue. Because the high prevalence of probable fatigue was found in such small enterprises, the authors suggest that a short interview with some quick questionnaires in health checkup for these small enterprise workers are helpful to early detect psychosocial and fatigue problems.

Risk of hip fractures in patients with depressive disorders: A nationwide, population-based, retrospective, cohort study.

BACKGROUND: Some studies have suggested that depressive disorders may play a vital role in the incidence of hip fractures. However, nationwide data are lacking regarding the association between depressive disorders and hip fractures. OBJECTIVE: We aimed to explore the association between depressive disorders and new-onset hip fractures. METHODS: We conducted a retrospective study of 11,207 patients with depressive disorders and 11,207 control patients using Taiwan's National Health Insurance Research Database. A Cox regression model was used to evaluate the risk of hip fractures in patients with depressive disorders. RESULTS: The incidence rate ratio of hip fractures between patients with depressive disorders and controls was 1.6 (95% confidence interval [CI] = 1.29-1.99, P < .001). After adjustment for potential confounders in multivariate analysis using the Cox regression model, patients with depressive disorders were found to have 1.34 times higher risk of hip fractures than controls (95% CI = 1.08-1.66, P = .008). Furthermore, age (hazard ratio [HR] = 7.43, 95% CI = 4.94-11.19, P < .001), hypertension (HR = 1.63, 95% CI = 1.17-2.28, P = .004), diabetes mellitus (HR = 1.47, 95% CI = 1.08-1.99, P = .014), cerebrovascular disease (HR = 1.76, 95% CI = 1.31-2.35, P < .001), living in rural areas (HR = 1.88, 95% CI = 1.30-2.70, P = .001), and low monthly income (NT$0-NT$19,000: HR = 4.08, 95% CI = 1.79-9.29, P = .001 and NT$19,100-NT$42,000: HR = 4.09, 95% CI = 1.76-9.49, P = .001) were independent risk factors for new-onset hip fractures in patients with depressive disorders. CONCLUSION: Depressive disorders might increase the risk of new-onset hip fractures, particularly in older patients and patients with hypertension, diabetes mellitus, cerebrovascular disease, or low socioeconomic status.

Factors related to incomplete flexible sigmoidoscopy among adult Chinese in Taiwan.

BACKGROUND: Sigmoidoscopy is effective in colorectal cancer screening, but incomplete examinations may overlook colonic pathologies and delay diagnosis. This study aimed to explore risk factors for incomplete insertions of flexible sigmoidoscopy among Taiwanese. METHODS: Healthy adults participating in health check-up in a tertiary medical center were invited for study. Subjects were recruited when they had fully consented and agreed to participate. Factors related to incomplete insertions of flexible sigmoidoscopy were evaluated and multivariate logistic regression was used to determine independent risk factors. A predictive model was generated by the risk factors identified. RESULTS: In total, 1,252 subjects (mean age, 53.9 13.1 years; age range, 2187 years; male/female,780/472) were enrolled, and 278 (22.2%) incomplete insertions were recorded. Multivariate analysis showed that female gender (odds ratio [OR], 2.06; 95% confidence interval [CI], 1.562.73; p < 0.001), age >or= 60 years (OR, 1.68; 95% CI, 1.262.23; p < 0.001), inadequate bowel preparation (OR, 1.66; 95% CI, 1.212.16; p = 0.001), history of constipation (OR, 2.43; 95% CI, 1.045.69; p = 0.042), and body mass index (BMI) < 25 kg/m2 (OR, 1.41; 95% CI, 1.051.89; p = 0.024) were all independent risk factors. The probability of incomplete insertion was significantly associated with the sum of the aforementioned risk factors (p < 0.001). Compared with subjects with no risk factors, the risks of incomplete insertions increased significantly among subjects bearing 1 risk factor (OR, 2.57; 95% CI, 1.474.49; p = 0.001), 2 risk factors (OR, 4.41; 95% CI, 2.527.39; p < 0.001), 3 risk factors (OR, 6.40; 95% CI, 3.5611.52; p < 0.001) and >or= 4 risk factors (OR, 10.00; 95% CI, 3.8925.70; p < 0.001). CONCLUSION: Female sex, age >or= 60 years, BMI < 25 kg/m2, history of constipation, and inadequate bowel preparation were independent risk factors for incomplete insertion of flexible sigmoidoscopy. Subjects with multiple risk factors may consider alternative modalities for colonic examination.

Illness: an opportunity for spiritual growth.

Spirituality is an innate aspect of being human, and every patient has the potential for spiritual growth through suffering from an illness. However, spirituality and spiritual care are rarely mentioned in the field of medicine, either because their definition can be ambiguous or because their nature can be highly personal. In a departure from the traditional biomedical view of health care, the author in this paper explores another aspect of the patient, hoping to inspire caregivers to be more attentive to the growth of a patient's spirituality. Furthermore, citing several clinical examples and by extrapolating the trajectory of human adaptation to illness, the author also delineates the proper compass of spiritual care and uncovers the distinction between spirituality, religion, and psyche.

Gender Differences in Outcome of an Attempt to Stop Smoking Among Smokers Attending a Smoking Cessation Clinic in Taiwan: 3-Year Follow-Up Study.

Studies that have examined gender differences in smoking cessation have produced mixed results. The purpose of the study was to examine whether there are gender differences in long-term smoking abstinence rates in smokers treated with nicotine patches at a smoking cessation clinic in Taiwan, where 39% of men and 5% of women smoke. This study included 1,065 smokers, comprising of 940 men and 125 women. Smokers were invited to attend the clinic every 1-2 weeks for a maximum of eight visits over 90 days, where they received prescriptions for nicotine patches, counseling, and educational materials. Participants were contacted by telephone at 1 and 3 years after the first visit and were asked whether they had smoked at all over the past 7 days. The results showed that women were significantly less likely than men to be abstinent at 1 year (adjusted odds ratio [aOR] = 0.64; 95% CI [confidence interval] = [0.41, 0.99]; p = .044) and 3 years (aOR = 0.44; 95% CI = [0.27, 0.74]; p = .02). More effective ways are needed to help female smokers quit in societies where smoking in women is rare and may be associated with social stigma.

A comparison of the effectiveness of varenicline and transdermal nicotine patch in outpatients following a standardized smoking cessation program in Southern Taiwan.

`Varenicline use has been shown to produce greater long-term smoking cessation rates than bupropion but has no clear differences compared to the transdermal nicotine patch. We performed this study to compare the effectiveness of varenicline with the nicotine patch at 3 and 6 months of follow-up of patients in an outpatient smoking cessation program provided by a hospital in Southern Taiwan. The sample consisted of 463 patients who attended the smoking cessation program at the outpatient family medicine clinic at Kaohsiung Veterans General Hospital between March 2006 and December 2008. All patients were aged ≥18 years and either smoked ≥10 cigarettes per day or scored ≥4 on the Fagerström Test for Nicotine Dependence. Patients were seen by a physician for up to 8 sessions in 90 days. Medication use was guided by patient preference (208 opted for varenicline and 255 for the nicotine patch). The primary outcomes of the study were self-reported 7-day point prevalence abstinence rates at 3 and 6 months from the first clinic visit. Varenicline users had a significantly higher abstinence rate than those using nicotine patch at 3-month (47.1% vs. 30.6%; odds ratio [OR] = 2.02, 95% confidence interval [CI] = [1.38, 2.96]) and 6-month follow-up (41.3% vs. 30.6%; OR = 1.60, 95% CI [1.09, 2.32]). Both groups had similar incidences of adverse events. Varenicline use in a sample of treatment-seeking-dependent smokers was associated with significantly higher abstinence rates than the nicotine patch.

[Spiritual care].

The essence of spirituality and spiritual care is too complex for clear definition. Topics of personal religious belief about life and death, an understanding or sensing of the process of dying, and the various means of influencing a patient's s body and mind may all be implied by the term "spiritual care". All care involving the patient's s thoughts or emotions tends to be put in the same basket, without any distinction between psychic needs, spiritual nature and religious belief. Spirituality connotes a person's s wholeness (body, mind and soul). Spirituality not only affects the individuals psychosocial activities, but also his or her physical condition and behavior. So, what is the scope of spiritual care? Does it include physical and psychological elements? Using clinical examples, the author seeks to clarify the role of spirituality in the process of adapting to a disease, and to expound a definition and goals of spiritual care. In addition, human spiritual needs and the elements of spiritual care are also outlined. It is hoped that this article will be helpful to nurses in their spiritual growth and to those who practice holistic care.

Prevotella brain abscesses and stroke following dental extraction in a young patient: a case report and review of the literature.

A brain abscess is a life-threatening infection. There are few reports describing Prevotella bacteremia with middle cerebral artery (MCA) occlusion and brain abscess following dental extraction in the literature. We herein describe a 32-year-old healthy man who experienced headache after tooth extraction. He was not correctly diagnosed until he experienced a stroke and a blood culture revealed Prevotella denticola weeks later. This case and our detailed review of related cases highlight the importance of thorough medical history-taking and clinical evaluations. Brain abscess formation should be considered in previously healthy patients with fever, stroke, and a recent history of tooth extraction.

Varenicline versus transdermal nicotine patch: a 3-year follow-up in a smoking cessation clinic in Taiwan.

RATIONALE: A network meta-analysis of randomized trials and real-world comparative studies strongly suggest that varenicline is more effective in aiding smoking cessation than single form nicotine replacement therapy (NRT). Modeling the health benefits attributable to this difference relies on extrapolation to lifetime cessation, but to date, follow-up has only extended to 12 months. Longer term follow-up data are helpful in checking these assumptions. OBJECTIVES: This study aimed to compare the sustained abstinence rates of smokers using varenicline versus nicotine patch in their quit attempt up to 36 months. METHOD: Five hundred eighty-seven smokers were recruited at Kaohsiung Veteran General Hospital between Feb 2006 and Aug 2009. Participants received counseling from a physician and received either varenicline (N=296) or the nicotine patch (N=291) for smoking cessation. Both varenicline and nicotine patch users could receive their medications for a maximum of 8 weeks. Participants were followed up by telephone at 3, 6, 12, and 36 months from the first visit. The primary outcome measure was self-reported sustained abstinence up to 36 months. Measures were also taken of smoking characteristics, cigarette dependence, and sociodemographic characteristics. RESULTS: Multiple logistic regression of 36-month sustained abstinence on to medication adjusting for other baseline variables showed a significant advantage for varenicline, OR=7.94 (95 % CI 1.87-33.74). CONCLUSION: An 8-week course of varenicline appears to yield higher abstinence rate up to 3 years than a similar length course of nicotine transdermal patch in routine clinical practice where behavioral support is available.

Prevalence and risk factors of asymptomatic colorectal polyps in taiwan.

Purpose. To investigate the prevalence and risk factors of hyperplastic and adenomatous colorectal polyps in a Taiwanese general population. Methods. From January 2009 to December 2011, consecutive asymptomatic subjects undergoing a routine health check-up were evaluated by colonoscopy. The colorectal polyps were assessed, and medical history and demographic data were obtained from each patient. Logistic regression analysis was conducted to search the independent risk factors for asymptomatic hyperplastic and adenomatous colorectal polyps. Results. Of the 1899 asymptomatic subjects, the prevalences of hyperplastic polyps and adenomatous polyps were 11.1% and 16.1%, respectively. Multivariate analysis revealed that high body mass index (BMI > 25: OR, 1.32, 95% CI, 1.05-1.71) and current smoking (OR, 1.87, 95% CI, 1.42-2.71) were independent predictors for hyperplastic colorectal polyps. Age over 60 years old (OR, 3.49, 95% CI, 1.86-6.51), high body mass index (BMI > 25: OR, 1.75, 95% CI, 1.21-2.71), heavy alcohol consumption (OR, 2.01, 95% CI, 1.02-3.99), and current smoking (OR, 1.31, 95% CI, 1.04-1.58) were independent predictors for adenomatous colorectal polyps. Conclusion. High BMI and smoking are common risk factors for both adenomatous and hyperplastic polyps. Old age and alcohol consumption are additional risk factors for the development of adenomatous polyps.

Prevalence and risk factors of asymptomatic peptic ulcer disease in Taiwan.

AIM: To investigate the prevalence and risk factors of asymptomatic peptic ulcer disease (PUD) in a general Taiwanese population. METHODS: From January to August 2008, consecutive asymptomatic subjects undergoing a routine health check-up were evaluated by upper gastrointestinal endoscopy. Gastroduodenal mucosal breaks were carefully assessed, and a complete medical history and demographic data were obtained from each patient. Logistic regression analysis was conducted to identify independent risk factors for asymptomatic PUD. RESULTS: Of the 572 asymptomatic subjects, 54 (9.4%) were diagnosed as having PUD. The prevalence of gastric ulcer, duodenal ulcer and both gastric and duodenal ulcers were 4.7%, 3.9%, and 0.9%, respectively. Multivariate analysis revealed that prior history of PUD [odds ratio (OR), 2.0, 95% CI: 1.3-2.9], high body mass index [body mass index (BMI) 25-30: OR, 1.5, 95% CI: 1.0-2.2; BMI > 30 kg/m(2): OR, 3.6, 95% CI: 1.5-8.7] and current smoker (OR, 2.6, 95% CI: 1.6-4.4) were independent predictors of asymptomatic PUD. In contrast, high education level was a negative predictor of PUD (years of education 10-12: OR, 0.5, 95% CI: 0.3-0.8; years of education > 12: OR, 0.6, 95% CI: 0.3-0.9). CONCLUSION: The prevalence of PUD in asymptomatic subjects is 9.4% in Taiwan. Prior history of PUD, low education level, a high BMI and current smoker are independent risk factors for developing asymptomatic PUD.

Emergency department (ED) utilization of oldest old men in a veterans care home in Taiwan.

ED is a common channel for older people to seek for medical services. However, unlike most care homes in the world, veterans care home in Taiwan has a constantly operating outpatient and inpatient services. Therefore, utilization of ED services among veterans care home may be different from most care home residents. Records of residents in Banciao Veterans Home residents visiting the ED of Taipei Veterans General Hospital from January to December of 2006 were retrospectively collected and analyzed. Demographic variables including age, sex, modes of arrival, category of triage, time of visit, main presenting symptoms, principal diagnosis, medical expenditure and the disposition after the ED visit or after admission to wards were carefully recorded. In total, 368 residents (mean age=81.9+/-5.9 years, all men) with 635 visits were identified. Nearly a half of Banciao Veterans Home residents had visited ED for at least once in 2006 and the medical expenditure was four times higher than other ED visitors. In average, 52.3% of ED visitors would be hospitalized and the most common diagnosis was infectious conditions. Onsite primary care geriatricians may play an important role in such settings.

Emergency department (ED) utilization and outcome of oldest old men presenting with geriatric syndromes in a veterans care home in Taiwan.

The first presentation of elderly people in the emergency department (ED) is commonly nonspecific and atypical, often in the form of geriatric syndromes, i.e. falls, immobility, incontinence, or deteriorating mental function. The purpose of this study was to evaluate the management and outcomes of institutionalized elderly people who initially presented with geriatric syndrome (GS) in the ED. A retrospective chart review of Banciao Veterans Care Home residents who visited the ED of a tertiary medical center was done. Demographic data including age, sex, modes of arrival, category of triage, time of visit, main presenting symptoms, principal diagnosis, medical expenditures, and clinical outcomes were recorded. From January to December, 2006, 629 ED visits (mean age, 82.1+/-5.3 years, all male) were retrieved. The overall prevalence of GS was 23.8%. When GS subjects were admitted, they were more likely to be transferred to step-down community hospitals for post-acute care (OR = 2.63; 95% CI: 1.36-5.08, p = 0.004). GS was common in institutionalized elderly people calling for ED services, and GS subjects were more likely to be transferred to step-down community hospitals after hospitalization. Comprehensive geriatric assessments may be of value for institutionalized elderly patients visiting the ED.

Overexpression of p27kip1 in urinary bladder urothelial carcinoma.

OBJECTIVES: Cyclins and cyclin-dependent kinase (CDK) complexes have important regulatory roles during cell cycle progression and can be used as prognostic markers in various kinds of malignant tumors. This study investigated the expression of proliferative cell nuclear antigen (PCNA), p53, Rb, p27(kip1), and cyclin D1 by immunostains in bladder tumors, especially urothelial papilloma, papillary urothelial neoplasm of low malignant potential, and low and high grade urothelial carcinoma, to see if their expression is associated with classification or grading of the urinary bladder urothelial carcinoma. METHOD: Nuclear expression of PCNA, p53, Rb, p27(kip1), and cyclin D1 was determined immunohistochemically in a series of 89 urinary bladder tumor specimens, including 13 papilloma, 15 urothelial neoplasm of low malignant potential, 17 low grade urothelial carcinoma, and 44 high grade urothelial carcinoma. The results of immunoreactivity were analyzed with respect to the associations with tumor grade. RESULTS: Eighty-two percent (38/45) of the p27(kip1) positive tumors were urothelial carcinoma, and the percentage of the p27(kip1) positivity was higher with increasing grade of the urothelial carcinoma (P = 0.011). A tendency of higher percentage of positive p53 immunoreactivity was noted in the urothelial carcinoma (P = 0.053). There was no significant difference in cyclinD1, Rb and PCNA expression between benign, low malignant potential and urothelial carcinoma. CONCLUSION: We first noted an overexpression of p27(kip1) in urinary bladder urothelial carcinoma. The result indicates that some urothelial carcinomas may tolerate this inhibitor of cell cycle progression.
