RESUMO

OBJECTIVE: Patients with schizophrenia are living at the border of society and their sexuality is often neglected. The aim of the study is to explore the association among The Brief Psychiatric Rating Scale (BPRS), quality of life (QoL), Taiwanese Depression Questionnaire, and Sexual Desire Inventory in people with schizophrenia (PwS). METHODS: This study used a cross-sectional design with 277 psychiatric inpatients. A descriptive analysis, difference analysis, and logistic regression model were presented to identify relevant variables that may affect the probability of good QoL. RESULTS: The study showed that male PwS had higher scores of standard deviation (SD) than females in PwS. The study also showed that smoking, early illness onset age, and shorter illness duration demonstrated a significantly higher SD. The logistic regression analysis showed that BPRS, depression, and SD significantly affected the probability of QoL. By structural equation model, SD would be positively correlated with mental status and SD would indirectly influence QoL. CONCLUSION: Our results showed psychological and sociological factors interactions may contribute to the QoL and SD for PwS. This study also demonstrated a close relationship between SD, depression, and BPRS. These factors may predict the probability of good life quality for the PwS.

RESUMO

OBJECTIVE: To determine whether ultrasound (US)-detected synovitis affects the therapeutic efficacy of hyaluronic acid (HA) injection for treating knee OA. METHODS: Patients with symptomatic knee OA were recruited. All the patients received HA injection two times at 2-week intervals. Clinical assessments were performed using a visual analogue scale (VAS) and the Western Ontario and McMaster Universities OA Index (WOMAC) at baseline and 1 and 6 months after treatment. Imaging evaluation was based on complete knee US examination and the Kellgren-Lawrence grading. Suprapatellar synovial fluid (SF) depth, synovial hypertrophy (SH) and vascularity were measured through US. RESULTS: In total, 137 patients who fulfilled the inclusion criteria were included in the analysis. All patients demonstrated improvement in VAS and WOMAC scores at 1 and 6 months after treatment (P < 0.001). Moreover, regression model-based analysis revealed significant associations of SF depth with the VAS and WOMAC scores in all patients. Each centimetre increase in the effusion diameter was associated with a decrease in the 1-month post-treatment VAS improvement percentage (15.26; 95% CI: 0.05, 29.5; P = 0.042) and 6-month post-treatment WOMAC improvement (37.43; 95% CI: 37.68, 50.69; P < 0.01). However, SH and vascularity were not significantly associated with VAS or WOMAC scores. CONCLUSION: Ultrasound detected suprapatellar effusion predicts reduced efficacy of HA injection in knee OA.

RESUMO

Infection with the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes the development of the novel 2019 coronavirus disease (COVID-19) and associated clinical symptoms, which typically presents as an upper respiratory syndrome such as pneumonia. Growing evidence indicates an increased prevalence of neurological involvement (e.g., in the form of stroke) during virus infection. COVID-19 has been suggested to be more than a lung infection because it affects the vasculature of the lungs and other organs and increases the risk of thrombosis. Patients with stroke are vulnerable to secondary events as a result not only of their poor vascular condition but also of their lack of access to rehabilitation resources. Herein, we review current knowledge regarding the pathophysiology of COVID-19, its possible association with neurological involvement, and current drug therapies. Suggestions are also offered regarding the potential for current neurorehabilitation therapies to be taught and practiced at home.

RESUMO

Coronavirus disease 2019 has severely affected public health. Under social distancing and lockdown policies, patients with musculoskeletal pain have fewer opportunities than usual to receive routine medical care for pain management in hospitals. Therefore, we provided some suggestions for such patients to manage musculoskeletal pain and techniques that may be performed at home during this period.

RESUMO

Buccal mucosa squamous cell carcinoma (BMSCC) is one of major subsites of oral cancer and is associated with a high rate of metastasis and poor prognosis. Heat shock proteins (HSPs) act as potential prognostic biomarkers in many cancer types. However, the role of HSPD1 in oral cancer, especially in BMSCC, is still unknown. Through data analysis with The Cancer Genome Atlas (TCGA), we found the association of HSPD1 gene expression with tumorigenesis and poor prognosis in oral cancer patients. Our cohort study showed that higher HSPD1 protein level was associated with tumorigenesis and poor prognosis in BMSCC patients with lymph node invasion, suggesting that HSPD1 may be involved in tumor metastasis. Moreover, knockdown of HSPD1 induced E-cadherin expression and decreased the migration and invasion of BMSCC cells. In contrast, ectopic expression of HSPD1 diminished E-cadherin expression and promoted the migration/invasion of BMSCC cells. Further, HSPD1 regulated RelA activation to repress E-cadherin expression, enhancing the migration and invasion of BMSCC cells. Furthermore, HSPD1 protein level was inversely correlated with E-cadherin protein level in tumor tissues and co-expression of high HSPD1/low E-cadherin showed a significant association with poor prognosis in BMSCC patients. Taken together, HSPD1 might repress E-cadherin expression and promote metastatic characters of BMSCC cells for poor prognosis of BMSCC patients.

RESUMO

BACKGROUND: COMT rs4680 Val158 allele is associated with high MB-COMT protein expression and elevated activity compared to the Met158 allele in post-mortem brains. A meta-analysis study suggested the link between COMT SNPs and MDD risk; in addition, MB membrane-bound (MB-COMT) specific genetic variation was reported that influences predisposition to depression amongst females. METHODS: Four tagSNPs, including rs4680, were genotyped. 268 MDD subjects and 223 controls were enrolled. MDD severity was rated by HDRS. Total-COMT and MB-COMT mRNA were detected by quantitative PCR. COMT protein and activity were assayed by western blot and methyltransferase assay, respectively. RESULTS: Haplotype TG of rs4633-rs4680, rs4646312 C, and rs4633 T allele might be linked to MDD vulnerability. Haplotype TG may interact with gender and affect MDD risk, since female haplotype TG carriers were estimated for a 9.17-fold higher risk than counterparts. COMT SNPs were not associated with HDRS scores. Haplotype TG female controls had higher MB-COMT protein, whereas non-TG female controls had higher soluble cytoplasmic (S-COMT) protein than other groups. COMT activity was much higher in controls than in MDD subjects. LIMITATIONS: Restricted numbers of homozygous TG carriers were recruited and analyzed for COMT mRNA, protein and activity. Only peripheral blood samples were used. CONCLUSIONS: A female-specific haplotype (haplotype TG)-MDD vulnerability association was found. TG female controls had higher MB-COMT protein and S-COMT. Altogether, high COMT protein and activity in female TG controls may be predisposing factors for enhanced MDD risk, though not correlated to MDD severity as rated by HDRS.

RESUMO

BACKGROUND: Sexual dysfunction occurs commonly in patients with psychiatric illness and may be related to the primary mental disorder, comorbidity with sexual disorders or medical illness, or medications used for mental disorders treatment, but the magnitude of this problem is unknown. AIM: To estimate the prevalence of current sexual activity, sexual dysfunction, and sexual attitude and influence of factors on patients with schizophrenia. METHODS: This study used a cross-sectional design with a total of 317 patients diagnosed with schizophrenia. The subjects completed a demographic questionnaire, sexual attitude scale, sexual dysfunction scale, and sexual behavior scale. Descriptive analysis, difference analysis, and logistic regression model were used to identify relevant variables that may affect sexual life quality. OUTCOMES: Age, sexual satisfaction, and patient symptoms may predict sexual life quality on patients with schizophrenia. RESULTS: The mean age of patients was 47.71 ± 9.54 years old. About the sexual activities, 53% of subjects had sexual intercourse experience, and 41.3% reported currently having sexual intercourse. The mean ± SD age for first sexual intercourse was 20.83 ± 5.95 years old (median was 20.0 years old). Moreover, women older than 50 years had significantly higher medians for the Brief Psychiatric Rating Scale (BPRS) score, higher proportions of sexual dysfunction, and lower proportions of feeling important to sexual life quality than men. For participants with age ≤50 years old, there was a significant relationship among BPRS group (mean score >2.5 vs ≤2.5), sexual dysfunction (P < .001), sexual life quality (P < .001), and sexual satisfaction (P = .006). Among the predictors of feeling important to sexual life quality, sexual satisfaction (odds ratio = 7.005, 95% CI = 4.126-11.892, P < .001) and BPRS score (odds ratio = 4.501, 95% CI = 2.042-9.923, P < .001) were significant independent factors after adding the interaction of age group and BPRS group. CLINICAL TRANSLATION: This study also reveals the close relationship between sexual satisfaction and BPRS score, which may predict sexual life quality of patients with schizophrenia. Limitations include the possibility of underreporting and bias associated with self-report measurement. CONCLUSION: Sexual life quality and sexual dysfunction on patients with schizophrenia are associated with interaction among psychological, sociological, and biochemical-pharmacological factors.

RESUMO

AIMS AND OBJECTIVES: This study aimed to evaluate the effectiveness of a sexual healthcare training programme for clinical nurses, with respect to knowledge, attitudes and self-efficacy concerning sexual healthcare. BACKGROUND: Inadequate sexual healthcare can result in poor treatment and quality of life for patients. Few studies have examined the development of sexual healthcare and related interventions from nurses' perspectives. DESIGN: The study included two stages involving focus groups and a quasi-experimental design. METHODS: The first stage consisted of an exploratory, descriptive session to assess nurses' perceptions and educational needs concerning sexual healthcare via two focus groups (N = 16). The second stage involved a quasi-experimental session to evaluate the training programme, based on the results of the first stage. In total, 117 nurses were recruited from a Taiwanese hospital; the experimental group (n = 59) completed a four-week (16 hours) training programme, and the control group (n = 58) did not participate in a training programme. Data were collected at four time points over 17 weeks. Longitudinal changes that occurred over time were examined using hierarchical linear models. RESULTS: The experimental group demonstrated significant improvements in knowledge (ß = 0·16, p < 0·01), attitude (ß = 0·18, p < 0·05), and self-efficacy (ß = 0·73, p < 0·001) scores. Relative to that of the control group, the experimental group showed significantly greater improvement in knowledge (ß = -0·12, p < 0·01) and attitudes regarding sexual healthcare (ß = -0·25, p < 0·05), but their improvement in self-efficacy concerning sexual healthcare was limited (p = 0·179). CONCLUSIONS: The training programme for sexual healthcare could exert positive and beneficial effects on nurses' development of knowledge regarding sexual healthcare and clarify their values and attitudes. RELEVANCE TO CLINICAL PRACTICE: The training programme could reduce challenges related to sexual healthcare issues in nursing care.

RESUMO

Relatively few studies have addressed the risk factors of erectile dysfunction (ED) in Taiwanese- most have described ED and medical problems in the general population. In this study, the cardiovascular risk factors of ED among aborigines in Taiwan were investigated. However, alcohol dependence (AD) was prevalent in Taiwan's aborigine population. So this study also focused on the relationship among AD, the cardiovascular risk factors and ED. A cross-sectional study was conducted, and data was obtained from a baseline survey of 192 aboriginal adults (35-75 years of age). The participants' demographic data, AD, markers of endothelial function, serum testosterone, and ED status were assessed. Ninety-four (49%) of the 192 participants had a history of alcoholism and 79 (84%) of those with alcoholism had ED. The study reported that AD and hyperlipidemia, metabolic syndrome (MetS), ED, abnormality of testosterone, and high-sensitivity C-reactive protein are highly prevalent among the aborigines. Factors that may affect ED included age, AD, central obesity, diabetes mellitus, hyperlipidemia, hypertension, MetS, and testosterone. ED is highly prevalent among aborigines with the risk factors of AD, MetS, old age, and abnormal testosterone serum level. MetS, atherosclerosis, and ED are risk factors for cardiovascular diseases. Hence, an increased focus on Taiwanese aborigines with ED is necessary.

RESUMO

BACKGROUND: Resistin, adipocyte-secreting adipokine, may play critical role in modulating cancer pathogenesis. The aim of this study was to investigate the effects of resistin on HCC adhesion to the endothelium, and the mechanism underlying these resistin effects. METHODS: Human SK-Hep1 cells were used to study the effect of resistin on intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) expressions as well as NF-κB activation, and hence cell adhesion to human umbilical vein endothelial cells (HUVECs). 5-Aminoimidazole-4-carboxamide 1-ß-D-ribofuranoside (AICAR), an AMP-activated protein kinase (AMPK) activator, was used to determine the regulatory role of AMPK on HCC adhesion to the endothelium in regard to the resistin effects. RESULTS: Treatment with resistin increased the adhesion of SK-Hep1 cells to HUVECs and concomitantly induced NF-κB activation, as well as ICAM-1 and VCAM-1 expressions in SK-Hep1 cells. Using specific blocking antibodies and siRNAs, we found that resistin-induced SK-Hep1 cell adhesion to HUVECs was through NF-κB-regulated ICAM-1 and VCAM-1 expressions. Moreover, treatment with AICAR demonstrated that AMPK activation in SK-Hep1 cells significantly attenuates the resistin effect on SK-Hep1 cell adhesion to HUVECs. CONCLUSIONS: These results clarify the role of resistin in inducing HCC adhesion to the endothelium and demonstrate the inhibitory effect of AMPK activation under the resistin stimulation. Our findings provide a notion that resistin play an important role to promote HCC metastasis and implicate AMPK may be a therapeutic target to against HCC metastasis.

RESUMO

INTRODUCTION: Obesity has been receiving an increasing amount of attention recently, but investigations regarding the potential impact of obesity, sexual behaviors, and sex hormones on erectile dysfunction (ED) in men have not completely clarified the association. AIM: To identify the relationship between ED, sexual behavior, sexual satisfaction, sex hormones, and obesity in older adult males in Taiwan. METHODS: Data were obtained from a baseline survey of 476 older adult males (≧40 years old). Their demographic data, body mass index (BMI), sex hormones, sexual desire, sexual satisfaction, and ED status were assessed. MAIN OUTCOME MEASURES: The International Index of Erectile Function-5 (IIEF-5), Sexual Desire Inventory (SDI), and Sexual Satisfaction Scale (SSS) were used to assess ED, sexual desire, and sexual satisfaction. RESULTS: In all, 476 men were available for analysis. The mean age of the sample was 51.34 ± 7.84 years (range 40 to 70 years). The IIEF total score had a mean of 19.44 ± 4.98; 264 (55.5%) subjects had ED, 250 (52.9%) were currently obese (BMI ≧27), and 297 (62.4%) had metabolic syndrome. The results showed an increased risk of ED among obese men and subjects with lower levels of sex hormones and lower sexual desire. Testosterone levels were lower in subjects with obesity (P < 0.001). Among the predictors of ED, obesity (odds ratio [OR] = 1.62, 95% CI = 1.07-2.44, P = 0.021), abnormal high sensitivity C-reactive protein (hs-CRP) (OR = 10.59, 95% CI = 4.70-23.87, P < 0.001), and lower serum full testosterone (OR = 3.27, 95% CI = 2.16-4.93, P < 0.001) were significantly independent factors. CONCLUSIONS: This study supports the idea of a close relationship between low levels of sex hormones, sexual desire, sexual satisfaction, obesity, and ED, and also shows that low free testosterone and hs-CRP may predict ED, even in obese populations.

RESUMO

The authors examined the association among sexual desire, sexual satisfaction, and quality of life in a sample of community participants. They predicted that quality of life would be positivity correlated with sexual satisfaction and that sexual desire would indirectly influence quality of life. This research showed that elderly adults' sexual desire and sexual satisfaction decrease with age and that nearly 40% of the interviewees still had sexual activity one or more times every month. The results revealed that sexual desire does not directly influence quality of life, but it does have a direct effect on sexual satisfaction; hence, sexual satisfaction will indirectly affect quality of life.

RESUMO

INTRODUCTION: Obesity is receiving growing research attention. However, investigations concerning the potential impact of obesity and testosterone on erectile dysfunction (ED) in young men have not been completely clarified. AIM: To identify the relationship between ED, serum testosterone level, and obesity in draftees in Taiwan. METHODS: Data were obtained from a baseline survey of 364 young adult military conscripts (19-24 years old). Their demographic data, body mass index (BMI), serum testosterone, and ED status were assessed. Sixty-four subjects had ED, and 300 comprised the normal control group. MAIN OUTCOME MEASURES: The International Index of Erectile Function-5 (IIEF-5), Sexual Desire Inventory, and Sexual Behavior Scale were used to assess ED, sexual desire, and sexual function. RESULTS: Three hundred sixty-four men were available for analysis. The mean age of the sample was 21.66 ± 0.92 years (19-24 years). The IIEF total score had a mean of 21.99 ± 2.34 and median of 23; 64 (17.6%) subjects had ED, although mild. The results showed an increased risk of ED among obese men and subjects with lower serum testosterone. Among the predictors of ED, obesity (odds ratio =83.97, 95% CI = 16.17-436.03, degrees of freedom [d.f.] = 1, P < 0.001) and lower serum testosterone (odds ratio = 679.84, 95% CI = 108.48-4,260.58, d.f. = 1, P < 0.001) were significantly independent factors. Testosterone levels were lower in subjects with obesity (P < 0.001). CONCLUSION: This study supports the idea that BMI and serum testosterone may provide warning signs of ED and, at the same time, an opportunity for early intervention in young men.

RESUMO

In recent years, attention has been focused on the anti-cancer properties of pure components, an important role in the prevention of disease. Andrographolide (Andro), the major constituent of Andrographis paniculata (Burm. F.) Nees plant, is implicated towards its pharmacological activity. To investigate the mechanism basis for the anti-tumor properties of Andro, Andro was used to examine its effect on cell-cycle progression in human colorectal carcinoma Lovo cells. The data from cell growth experiment showed that Andro exhibited the anti-proliferation effect on Lovo cells in a time- and dose-dependent manner. This event was accompanied the arrest of the cells at the G1-S phase by Andro at the tested concentrations of 0-30 microM. Cellular uptake of Andro and Andro was confirmed by capillary electrophoresis analysis and the intracellular accumulation of Andro (0.61+/-0.07 microM/mg protein) was observed when treatment of Lovo cells with Andro for 12h. In addition, an accumulation of the cells in G1 phase (15% increase for 10 microM of Andro) was observed as well as by the association with a marked decrease in the protein expression of Cyclin A, Cyclin D1, Cdk2 and Cdk4. Andro also inducted the content of Cdk inhibitor p21 and p16, and the phosphorylation of p53. Further immunoprecipitation studies found that, in response to the treatment, the formation of Cyclin D1/Cdk4 and Cyclin A/Cdk2 complexes had declined, preventing the phosphorylation of Rb and the subsequent dissociation of Rb/E2F complex. These results suggested Andro can inhibit Lovo cell growth by G1-S phase arrest, and was exerted by inducing the expression of p53, p21 and p16 that, in turn, repressed the activity of Cyclin D1/Cdk4 and/or Cyclin A/Cdk2, as well as Rb phosphorylation.
