Objective
Atrial fibrillation is the most common cardiac arrhythmia and a known risk factor for cerebrovascular stroke. Atrial fibrillation and longstanding hypertension may produce ischemic lesions leading to progressive cognitive impairment. The impact of atrial fibrillation alone on cognitive impairment has not been evaluated. Our objective was to compare cognitive function, quality of life, psychological distress, and impulsiveness in people with atrial fibrillation and a matched control group.Methods
The study included 60 patients. The first group of patients were ≥55 years of age, with ≥5 years history of atrial fibrillation, without hypertension (or with well-controlled hypertension), without previous dementia, compared with a matched group of 30 healthy control participants. Demographic and clinical characteristics were recorded. Subjects underwent the following rating scales: Mini-Mental State Examination, Hospital Anxiety and Depression, Heart Quality of Life, and Barratt Impulsiveness Scale.Results
In the atrial fibrillation group there were 63% male (n = 19) and 37% female (n = 11) patients; the control group was 33% male (n = 10) and 67% female (n = 20). Age range was from 55 to 81 years in both groups, mean = 63.9 years (±6.4) in the atrial fibrillation group and 66.1 years (±8.0) in controls.In the atrial fibrillation group, 23.3% had primary or general education, college – 23.3% and university – 53.3%; in the control group – 20%, 23.3%, and 56.7%, respectively. Mini-Mental State Examination score was 27.6 (±1.6) in the atrial fibrillation group vs 29.5 (±0.73) in the control group (P < .0001). Anxiety disorders were observed in 20 patients (66.7%) in atrial fibrillation vs 8 patients (26.67%) in the control group (P = .009). Heart Quality of Life mean score was 1.4 (±0.65) in the atrial fibrillation and 2.6 (±0.35) in the control group (P < .0001). Physical subscale mean scores were 1.4 (±0.74) in atrial fibrillation vs 2.8 (±0.18) in the control group (P < .0001).Conclusion
Individuals with atrial fibrillation are more likely to develop anxiety disorder. Cognitive status is significantly lower in the atrial fibrillation group. In comparison with healthy subjects, individuals with atrial fibrillation have worse quality of life. 相似文献2.

Molecular characterization of isoniazid-resistant Mycobacterium tuberculosis clinical isolates in Lithuania 总被引:1,自引:0,他引:1 下载免费PDF全文

Mutations at codon 315 of the katG gene were detected in 312 of 364 (85.7%) isoniazid-resistant Mycobacterium tuberculosis isolates. Seven of 52 (13.5%) isoniazid-resistant isolates with the wild-type Ser315 codon and 10 of 52 (19.2%) isoniazid-resistant isolates with a mutated katG allele had mutation -15C-->T in the promoter of the mabA-inhA operon. 相似文献

Research on widespread pain often relies upon case definitions bounded by duration limits or “cut-offs.” In clinical reality, however, there are no natural cut-off points between localized and widespread pain. Rather, pain is best represented by a continuum of “widespreadness” from localized pain to pain spread across the body. The objective of this paper was to describe the number of pain sites (NPS) reported in a population study and its association with demographic, lifestyle, and health-related factors. Using a cross-sectional design, the Standardized Nordic Questionnaire was used to measure musculoskeletal pain among seven age groups in Ullensaker, Norway (n = 2926). Results showed that women reported a higher mean NPS than men. A higher NPS was also found for individuals who were separated or divorced, undergoing rehabilitation, or who had a disability pension. Additionally, greater NPS was reported by smokers, individuals with less physical activity, and a higher BMI. A strong linear relationship was found between NPS and reduction in overall health, sleep quality, and psychological health. Results from a multivariate linear regression analysis showed that overall health, sleep quality, and gender demonstrated the strongest associations with increasing NPS, accounting for 31.4% of the variance. Our study indicates that the straightforward and simple method of counting the NPS could be important in managing the complex problem of musculoskeletal pain. 相似文献

The present study analyzed the bactericidal effect of methylene blue associated with low-level lasers on Escherichia coli isolated from a pressure ulcer. Microbiological material from a pressure ulcer was isolated using an aseptic swab, and antimicrobial activity was verified using the diffusion disc method. Methylene blue was used at concentrations of 0.001 and 0.005%, and low-level lasers of 670, 830, and 904 nm, with the energy densities of 4, 8, 10, and 14 J/cm2, were tested on three plates each and combined with methylene blue of each concentration. In addition, three control plates were used, with each concentration and energy density separated without any interventions. The results were analyzed using the paired sample t test to determine the bactericidal effect of the methylene blue and using the ANOVA test to compare the effects of the energy densities and wavelengths among the low-level laser treatment protocols. The results showed bacterial reduction at wavelengths of 830 and 904 nm and more proliferation in wavelengths of 670 nm. In wavelength of 830 nm, a bacterial reduction was observed in the conditions with 0.001% methylene blue in all energy density utilized, with 0.005% methylene blue in energy density of 10 J/cm2, and without methylene blue in energy density at 10 J/cm2. And in a wavelength of 904 nm, all condition showed bacterial reduction with or without methylene blue. We concluded that the low-level lasers of 904 and 830 nm have bactericidal effects and at better energy densities (10 and 14 J/cm2). 相似文献
