Background: Increased IL-6 level, M2 macrophages and PD-1+CD8+ T cells in tumor microenvironments (TME) have been identified to correlate with resistance to checkpoint blockade immunotherapy, yet the mechanism remains poorly understood. Rab small GTPase-mediated trafficking of cytokines is critical in immuno-modulation. We have previously reported dysregulation of Rab37 in lung cancer cells, whereas the roles of Rab37 in tumor-infiltrating immune cells and cancer immunotherapy are unclear. Methods: The tumor growth of the syngeneic mouse allograft in wild type or Rab37 knockout mice was analyzed. Imaging analyses and vesicle isolation were conducted to determine Rab37-mediated IL-6 secretion. STAT3 binding sites at PD-1 promoter in T cells were identified by chromatin immunoprecipitation assay. Multiplex fluorescence immunohistochemistry was performed to detect the protein level of Rab37, IL-6 and PD-1 and localization of the tumor-infiltrating immune cells in allografts from mice or tumor specimens from lung cancer patients. Results: We revealed that Rab37 regulates the secretion of IL-6 in a GTPase-dependent manner in macrophages to trigger M2 polarization. Macrophage-derived IL-6 promotes STAT3-dependent PD-1 mRNA expression in CD8+ T cells. Clinically, tumors with high stromal Rab37 and IL-6 expression coincide with tumor infiltrating M2-macrophages and PD1+CD8+ T cells that predicts poor prognosis in lung cancer patients. In addition, lung cancer patients with an increase in plasma IL-6 level are found to be associated with immunotherapeutic resistance. Importantly, combined blockade of IL-6 and CTLA-4 improves survival of tumor-bearing mice by reducing infiltration of PD1+CD8+ T cells and M2 macrophages in TME. Conclusions: Rab37/IL-6 trafficking pathway links with IL-6/STAT3/PD-1 transcription regulation to foster an immunosuppressive TME and combined IL-6/CTLA-4 blockade therapy exerts potent anti-tumor efficacy.

Few studies have addressed the impact of diagnostic urine metabolites and the clinical outcomes associated with genitourinary urothelial (GU) cancer to date. Furthermore, longitudinal analysis of the dynamics of urine metabolites contributing to the detection of GU cancer has not yet been fully investigated; therefore, the discovery of novel diagnostic urine biomarkers is of enormous interest. We explored the correlation of the urine metabolomic profiles to GU cancers. The aqueous metabolites of the GU cancer and the control were also identified and analyzed through high-resolution1H nuclear magnetic resonance (NMR) spectroscopy. Compared with the control, the urine metabolites of the tumor were studied in relation to changes over time in a linear mixed model for repeated measures. The urine metabolites of sixty-three (44 male and 19 female) patients with GU cancers were systemically analyzed. The urine metabolite profile in GU cancer was significantly higher than those in the control group (p

Background Tuberculosis (TB) is one of the world’s major communicable infectious diseases, and it still imposes a great health burden in developing countries. The development of drug-resistant TB during the treatment increases the treatment complexity, and the long-term pulmonary complications after completing treatment raise the epidemic health burden. This study intended to investigate the utilization of Chinese medicine (CM) for respiratory symptoms by patients with a medical history of TB in Taiwan. Methods We analyzed a cohort of one million individuals who were randomly selected from the National Health Insurance Research Database in Taiwan. The inclusion criteria of patients (n = 7905) with history of TB (ICD-9-CM codes 010–018 and A02) were: (1) TB diagnosed between January 1, 1997 and December 31, 2010 (2) 18 years old or over (3) Clinical records for at least 2 months with complete demographic information (4) Record of treatment with first-line TB medication prescriptions. CM users for conditions other than respiratory discomforts (n = 3980) were excluded. Finally, a total of 3925 TB patients were categorized as: CM users for respiratory discomforts (n = 2051) and non-CM users (n = 1874). Results Among the 3925 subjects, 2051 (52.25%) were CM users, and 1874 (44.753%) were non-CM users. Female patients and those who were younger (18–39 y/o) and who lived in urbanized areas relatively tended to be CM users (p

Many family caregivers are also employed full- or part-time and are known to be affected by job demands. This study explored the mediating effect of job demands on the relationship between caregiving demands and caregiver health outcomes in primary family caregivers of older persons with dementia in Taiwan (N = 214). A cross-sectional design using a self-completed structured questionnaire was implemented. Structural equation modeling analyses showed that job demands partially mediated the relationship between caregiving demands and caregiver health outcomes. The indirect effect of caregiving demands on caregiver health outcomes through job demands was 0.208 (95% confidence interval: 0.053 - 0.335). Nurses should evaluate job demands when screening for high-risk caregiver groups vulnerable to high caregiving demand. Interventions aimed at lessening both caregiving demands and job demands may improve caregiver health outcomes for family caregivers of older adults with dementia.

Prostate cancer is one of the most common seen malignancies and the leading cause of cancer-related death among men. Given the importance of early diagnosis and treatment, it is worth to identify a potential novel therapeutic target for prostate cancer. Mucosa-associated lymphoid tissue 1 (MALT1) is a novel gene involved in nuclear factor κB (NF-κB) signal transduction by acting as an adaptor protein and paracaspase, with an essential role in inflammation and tumorigenesis in many cancers. This study investigated the functions and the potential regulatory mechanisms of MALT1 in the human prostate cancer cells. We found that MALT1 is abundant in prostate cancer tissues. MALT1 facilitated NF-κB subunits (p50 and p65) nuclear translocation to induce gene expression of interleukin 6 (IL-6) and C-X-C motif chemokine 5 (CXCL5) in prostate carcinoma cells. MALT1 promoted cell proliferation, invasion, and tumor growth in vitro and in vivo. MALT1 enhanced NF-κB activity in prostate carcinoma cells, moreover, NF-κB induced MALT1 expression determined by reporter and immunoblot assays, implying there is a positive feedback loop between MALT1 and NF-κB. In conclusion, MALT1 is a NF-κB-induced oncogene in the human prostate carcinoma cells.

Caffeic acid phenethyl ester (CAPE), a bioactive component of propolis, has beneficial effects on cancer prevention. Growth differentiation factor 15 (GDF15) is an antitumor gene of bladder cancer. Therefore, this study investigated the anti-cancer effect of CAPE on bladder carcinoma cells and related mechanisms.The expressions of GDF15, N-myc downstream-regulated gene 1 (NDRG1), and maspin, and the activations of extracellular signal regulated kinase (ERK), c-jun Nterminal kinase (JNK), p38, and 50 adenosine monophosphate-activated protein kinase (AMPK) α1/2 in human bladder cells after gene transfection or knockdown were determined by immunoblot, real-time reverse transcriptase-polymerase chain reaction (RT-qPCR), and reporter assays. The assays of 5-ethynyl-2'-deoxyuridine (EdU), CyQUANT cell proliferation, and Matrigel invasion, and the xenograft animal study were used to assess the cell proliferation, invasion, and tumorigenesis.GDF15 expression in epithelial cells was negatively correlated with neoplasia in vitro. Also, GDF15 exhibits in bladder fibroblasts and smooth muscle cells. CAPE-induced expressions of NDRG1 and maspin decreased cell proliferation and invasion of bladder carcinoma cells in a GDF15-dependent manner in vitro. The xenograft animal study suggesting CAPE attenuated tumor growth in vivo. CAPE increased phosphorylation of ERK, JNK, p38, and AMPKα1/2 to modulate the GDF15 expressions. Pretreatments with ERK, JNK, or p38 inhibitors partially inhibited the CAPE effects on the inductions of GDF15, NDRG1, or maspin. Knockdown of AMPKα1/2 attenuated the CAPE-induced GDF15 expression and cell proliferation in bladder carcinoma cells.Our findings indicate that CAPE is a promising agent for anti-tumor growth in human bladder carcinoma cells via the upregulation of GDF15.

Introduction: The effects of Gassless single port retroperitoneoscopic surgery with urologic diseaseremain unclear. In this retrospective review, we aim to elucidate the effect of the Gassless retroperitoneoscopy for urologic disease. Methods: We retrospectively enrolled five consecutive patients who visited the urologic department for urologic disease from January 2016 to October 2016. All cases were followed up at least 12 months postoperatively. Of these, two renal mass, two adrenal tumors and one ureter stricture were reports. Result: There were no significant differences between the characteristics of these groups. (p

Background Despite controversy, an association between allergy and nocturnal enuresis (NE) has been reported for almost a century. Allergic rhinitis (AR)-associated sleep-disordered breathing frequently results in microarousals during sleep, decreased sleep efficiency, and change in sleep pattern and behavior. NE is a common sleep disorder in children. Hence, this study aimed to investigate the incidence and risk of NE in children with AR. Methods A population-based cohort study was conducted among 327,928 children with AR and 327,601 non-AR controls between 2000 and 2012 in Taiwan. By the end of 2012, the incidence of NE in both cohorts, and the AR-to-non-AR cohort hazard ratios (HRs) were measured. Results The adjusted HR of NE during the study period was 1.7-fold higher in the AR cohort compared to the non-AR cohort. The risk was greater for boys, children younger than 6 years old, those with comorbidities of asthma, atopic dermatitis, and attention deficit/hyperactivity disorder (ADHD), and those who had more than 5 AR-related medical visits per year. The risk of NE in the AR cohort decreased with follow-up time and was the highest within the first year after AR diagnosis. Conclusion Children with AR had a higher incidence and subsequent risk of NE. The risk of NE was greater for boys, younger children, and those with more frequent health utilization for AR symptoms.

Pei-Shan Yang,1 Chien-Lun Chen,1 Chen-Pang Hou,1 Yu-Hsiang Lin,1 Ke-Hung Tsui1,2 1Department of Urology, 2Prostate Health Laser Center, Chang Gung Memorial Hospital-Linkou, Chang Gung University, College of Medicine, Taipei, Taiwan, Republic of China Purpose: The aim of this study was to investigate the efficacy and tolerability of switching from 0.2mg tamsulosin to 0.4mg tamsulosin oral controlled absorption system (OCAS) over a 12-week period in Taiwanese men with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). Patients and methods: Taiwanese male patients who were dissatisfied with treatment with 0.2mg tamsulosin were enrolled in this clinical study and switched to 0.4mg tamsulosin OCAS. Efficacy was assessed over a 12-week period by an International Prostate Symptom Score (IPSS) questionnaire and analysis of urinary flow by uroflowmetry. Results: A statistically significant improvement was observed in total IPSS scores from baseline (14.94±7.41, moderate) to 12weeks (7.36±5.77, mild) in 81 patients who were switched from 0.2 to 0.4mg tamsulosin OCAS (P

Background Capillarisin (Cap), an active ingredient of Artemisia capillaris extracts, has known for its anti-inflammatory, antioxidant, and anticancer properties. Functions of Cap in prostate cancer are not clear. We investigate effects of Cap on downregulation of prostate specific antigen (PSA) via modulation of androgen receptor (AR) in prostate carcinoma cells. Methods Cell proliferation was measured by water-soluble tetrazolium-1 (WST-1) cell proliferation assays. The PSA and AR expressions were assessed by immunoblotting and RT-qPCR assays. Effects of Cap on PSA expressions were determined by ELISA, immunoblotting, and reporter assays. Co-immunoprecipitation and immunoblotting assays were used to define the effects of Cap on dissociation of AR-heat shock protein 90 (Hsp90) interaction. Results Cap inhibited LNCaP cell growth in a dose- and/or time-dependent way without inducing poly ADP-Ribose Polymerase (PARP) cleavage. Cap not only effectively suppressed AR and PSA protein expressions, but also attenuated activations of synthetic androgen (R1881) on PSA promoter activity dose- and time-dependently. The Cap pretreatment abrogated effects of R1881 on AR activity by reducing AR translocation to the nucleus. Immunoblotting assays indicated that Cap promoted a degradation of AR proteins dose-dependently in either cycloheximide pretreated-LNCaP cells or AR-ectopic expressed PC-3 cells. Pretreatment of MG132, a proteasome inhibitor, attenuated effect of Cap on AR degradation. Cap lessened AR stability by dissociation of AR-Hsp90 interaction. Conclusions Our results indicated that Cap inhibited growth of LNCaP cells. Cap effectively suppressed androgen activation on AR-mediated transactivation, which is AR-dependent through AR degradation and dissociation of AR-Hsp90 in prostate carcinoma cells.

To evaluate the surgical outcomes of stroke patients with symptomatic benign prostatic hyperplasia (BPH) who underwent transurethral resection of the prostate (TURP) and compare the clinical outcomes between patients with stroke and those without stroke receiving this procedure.This retrospective cohort study analyzed claims data collected during the period of 1997-2012 from Taiwan National Health Insurance Research Database. We enrolled 6625 patients who had persistent lower urinary tract symptoms and underwent TURP for BPH. They were categorized into a stroke (n = 577) and nonstroke (n = 6048) group. Patient characteristics, postoperative clinical outcomes, medication records, and medical expenses were compared.Compared with the stroke group patients, those in the nonstroke group were younger, had fewer comorbidities, and more favorable postoperative clinical outcomes. Nevertheless, TURP achieved favorable outcomes in stroke patients with symptomatic BPH. In the stroke group, the rate of urinary tract infection (UTI) decreased from 34.7% during 1 year preoperatively to 29.8% during 1 year postoperatively (p = .05). The rate of urinary retention (UR) also decreased from 55.5% during 1 year preoperatively to 22.5% during 1 year postoperatively (p = .05). TURP reduced the overall medical expenses of patients with stroke. Annual patient medical expense during 1 year preoperatively, 1 year postoperatively, 2 years postoperatively, and 3 years postoperatively was NT$659,000, NT$646,000, NT$560,000, and NT$599,000, respectively.In patients with stroke, TURP reduces the risks of UTI and UR and annual total medical expense.

Purpose: To analyze the outcomes of thulium vapoenucleation of the prostate (ThuVEP) in the management of benign prostatic hyperplasia. The outcomes of this increasingly popular procedure are yet to be confirmed in patients with various prostate sizes and health status. Materials and methods: Three hundred and three patients who underwent ThuVEP were included and stratified in subgroups according to prostate size and age. We analyzed patient demographics, preoperative disease-related parameters, and perioperative and follow-up results. Correlation of prostate size and operation time were also assessed. Results: Baseline mean prostate volume was 61.0 mL (range 19.3–226 mL), mean urinary peak flow rate (Qmax) was 8.6 mL/second (range 1.4–23.25 mL/second), mean postvoid residual volume was 126.2 mL (range 0–649 mL) and mean International Prostate Symptom Score was 25.1 (range 8–35). The mean operation time was 84.0 minutes and 88.6 minutes for total and prostate volume >80 mL, respectively. After laser surgery, there were mean reductions of 5.3 ng/mL, 7.5 ng/mL, 3.7 ng/mL, and 3.5 ng/mL (38.0%, 49.7%, 30.3%, and 36.5% change from baseline) in prostate-specific antigen level among the four groups. As for postvoid residual volume, there was a significant reduction in volume in the total, prostate volume >80 mL and prostate volume

To identify dementia-friendly communities' indicators and their current conditions in Taiwan from the perspectives of people with dementia and dementia-family caregivers.This qualitative study explored the opinions and experiences of people with dementia and dementia-family caregivers regarding dementia-friendly communities.Participants (16 people with dementia and 20 family caregivers) were recruited from neurological clinics, day care centres for people with dementia and support groups for family caregivers in the Taipei community from July - October, 2016. Data were collected in face-to-face interviews, which were tape recorded and transcribed verbatim. Transcripts were analysed by Miles and Huberman's (1994) guidelines.Similar indicators for dementia-friendly communities were identified in Taiwan as in other countries, including dementia-friendly care services, dementia-friendly hospitals, dementia-friendly community environment, dementia-friendly transportation, dementia-friendly stores and shops, dementia friendly people, integrated dementia-related information and community contribution- and -involvement opportunities for people with dementia. However, Taiwanese people with dementia and family caregivers described no emphasis on the potential of people with dementia to contribute to developing dementia-friendly communities and more top-down expectations for the government's role.These indicators can be a guide for developing and evaluating dementia-friendly communities in Taiwan. Differences between Taiwan and Western developed countries in indicators for dementia-friendly communities can be further explored. Community nursing assessment, interventions, and evaluation based on these dementia-friendly communities indicators can be further developed.This study developed indicators for dementia-friendly communities in an Asian country. These indicators can be used as a guide for developing and evaluating dementia-friendly communities.目的: 根据痴呆患者和痴呆家庭照顾者的意见,制定痴呆友好社区指标以及台湾目前的痴呆友好社区指标。 设计: 此定性研究主要内容是探讨痴呆患者和痴呆家庭照顾者关于痴呆友好社区指标的观点。 方法: 从2016年7月到10月,研究参与者(16位痴呆患者和20 位痴呆家庭照顾者)都是来自台北社区的神经学诊所、痴呆患者日托中心、家庭照顾者的相关专业人士。 结果: 得出的台湾痴呆友好社区指标与其他国家类似,指标包括痴呆友好护理服务、痴呆友好医院、痴呆友好社区环境、痴呆友好交通、痴呆友好商店、痴呆友好人员、完善痴呆信息、社区贡献与痴呆患者参与机会。但是,台湾的痴呆患者和痴呆家庭照顾者表示并不期待痴呆患者和政府会为建设痴呆友好社区做出贡献。 结论: 台湾痴呆友好社区指标与西方发达国家痴呆友好社区指标的不同值得我们进一步研究。根据痴呆友好社区指标发展社区护理评估、干预措施和评估等。 影响: 此研究发现了亚洲国家痴呆友好社区指标。研究得出的指标可用作指南,引导发展和评估痴呆友好社区。.

The surgical outcomes of patients with single ureteral stones who had undergone ureteroscopic Holmium laser lithotripsy as outpatients and compare them with those of patients who had received the same procedure as inpatients. Records were obtained from January 2012 to December 2016 for selected patients who had undergone the above mentioned procedure at our institution. Patients were excluded if their ECOG performance status was ≥2, presented with multiple stones or concomitant renal stones, had histories of cancer or congenital urinary system abnormalities, or had undergone urinary system reconstruction surgery. Patients could decide whether to receive the procedure as an outpatient or inpatient. All surgeries were performed by a single surgeon. Patients preoperative, operative, and postoperative data were recorded. The clinical results, such as urinary tract infection, analgesic requirement, rate of returning to the emergency room, stone clearance, surgical complications, and medical expenditure for the treatment courses were analyzed and compared between the 2 cohorts. In total, 303 patients met the inclusion criteria. Among them, 119 patients decided to receive ureteroscopic laser lithotripsy as outpatients, whereas 184 decided to be inpatients. The outpatient cohort was younger (P

Traditional Chinese medicine (TCM) has been used for over two thousand years to treat motor impairments corresponding to the clinical manifestations of Parkinson's disease (PD).This study aimed to investigate the prescription of Chinese herbal medicine (CHM) for the management of PD and further determine whether CHM can improve motor function and decrease the risk of incident fracture.Patients older than 40 years newly diagnosed with PD between January 1997 and December 2010 were selected from the National Health Insurance Research Database (NHIRD) and followed up until the end of 2013. We used 1:1 frequency matching by age, sex, index year, and initial diagnostic year to compare the TCM users and non-TCM users. We used a Cox regression model and the Kaplan-Meier method to estimate the risk of developing fracture among the TCM and non-TCM users.In total, 7197 patients older than 40 years were newly diagnosed with PD between 1997 and 2010 in Taiwan. Among these patients, 3456 were TCM users, and 3730 were non-TCM users. We compared 2007 PD patients with comparable demographic characteristics and comorbidity profiles between the two cohorts. During the follow-up period, compared with the non-TCM cohort, fewer patients in the TCM cohort had incident fractures (adjusted hazard ratio: 0.5, 95% CI: 0.44-0.56). The cumulative incidence of fracture was lower in the TCM cohort (log-rank test, p 0.0001). Shi-Chang-Pu (Acorus gramineus Aiton), Yuan-Zhi (Polygala tenuifolia Willd), Bei-Mu (Fritillaria cirrhosa D. Don), Hai-Piao-Xiao (Sepiella maindronide Rochebrune; Sepia esculenta Hoyle), and Tian-Ma (Gastrodia elata Blume) constituted the core Chinese herbal medicine prescriptions used to treat PD patients.The present study identified the core prescription pattern for the management of PD in Taiwan. Complementary CHM therapy was associated with a reduced risk of fracture in PD patients.

Background To evaluate the long-term surgical outcomes of patients with urinary retention (UR) caused by a benign prostatic obstruction (BPO) who underwent transurethral resection of the prostate (TURP), and compare their outcomes with those of patients who received medication without surgical intervention. Methods This retrospective cohort study analyzed claims data collected during the period of 1997–2012 from Taiwan’s National Health Insurance Research Database. We examined geriatric adverse events among patients who had received a diagnosis of symptomatic benign prostatic hyperplasia and whom experienced UR, and compared those who received TURP and medication only. Primary outcomes included urinary tract infection (UTI), UR, inguinal hernia, hemorrhoids, stroke, acute myocardial infarction, and bony fracture. We excluded patients who had concomitant prostate cancer, bladder cancer, or a long-term urinary catheter indwelling, as well as those who did not receive α-blocker medication regularly. Those aged 90 years were also excluded. The enrolled patients were categorized into TURP (n = 1218) and medication only (n = 795) groups. After 1:1 propensity score matching, we recorded and compared patients’ characteristics, postoperative clinical outcomes, and geriatric adverse events. Results The TURP cohort had a lower incidence of UTI and UR during the postoperative follow-up period from 2 months to 3 years than did the medication only group (20.7% vs. 28.9% and 12.5% vs. 27.6%, respectively, p

Methods: This analysis was a retrospective cohort study using 13years (2000–2012) of claims data from Taiwan’s National Health Insurance Research Database (NHIRD). A total of 4,887 patients who had persistent LUTSs and underwent TUR-P for prostate enlargement (benign prostate enlargement [BPE]) were enrolled and divided into two groups: DM and non-DM groups. The patients’ characteristics, postoperative clinical outcomes, and the medication records after TUR-P were compared. Chi-square test was used for categorical variables and independent samples t-test for continuous variables. Multivariable logistic regression analysis was used to compare the risk of postoperative outcomes. Finally, we estimated the medication-free survival rate after TUR-P using Kaplan–Meier method and compared it between study groups using log-rank test. Results: DM group patients had a higher prevalence of comorbidities. Postoperatively, the DM group had lower rates of urinary tract infection (UTI; odds ratio [OR], 0.78; P=0.009) and higher rates of urinary retention requiring catheterization (OR, 1.35; P=0.01) within 1month after TUR-P. A higher proportion of patients with DM took anti-muscarinics (OR, 1.23; P=0.032) within the first 3months and α-blockers (OR, 1.18; P=0.049) during 3–12months after receiving TUR-P. Overall, the DM group patients had a worse postoperative medication-free survival compared to that of non-DM group patients (95% confidence interval [95% CI], 1.14; P=0.005). Conclusion: DM patients require higher rates of continuing medication after TUR-P, especially anti-muscarinics in 3months postoperatively and alpha-blocker after 3months postoperatively. DM patients also had higher incidence of urine retention after surgery. DM patients had relatively poor treatment outcomes compared to DM-free patients.

A challenge facing dementia service providers is how to detect dementia early to facilitate timely intervention. This article reports findings of an evaluation study of a dementia-screening program in Taiwan utilizing the Theory of Planned Behaviors. We present the Short Portable Mental Status Questionnaire (SPMSQ) program rationale and examine the effects of this important health and social service intervention. Follow-up telephone interviews were completed by 108 respondents. Findings indicate that the SPMSQ program was successful in identifying suspected dementia. Results also show that the dementia-screening program contributed to an increase in medical service utilization and in unpaid informal care.

Aim To report the moderating effects of work-related conditions and interactive family-care-giving variables, including mutuality and preparedness, on caregiver role strain and mental health for family caregivers of patients with dementia. Background Few studies have examined the interrelationships among caregivers' working conditions, care-giving dynamics and caregiver well-being. Design Cross-sectional, correlational study. Methods Data were collected by self-completed questionnaires from 176 primary family caregivers of patients with dementia in Taiwan from May 2005-January 2006. Caregiver role strain and mental health were analysed by multiple regressions using a hierarchical method to enter independent variables and two- and three-way interaction terms after controlling for caregiver age and gender, employment status, and work flexibility and the simple effect of each independent variable. Results More preparedness was associated with less role strain for family caregivers with less work/care-giving conflict. More care-giving demand was associated with poorer mental health only for caregivers with low work/care-giving conflict and with average and low preparedness, but not high preparedness. For family caregivers with less work/care-giving conflict, more preparedness decreased role strain and maintained mental health even when care-giving demand was high. Conclusion These results provide a knowledge base for understanding complex family caregiver phenomena and serve as a guide for developing interventions. Future studies with longitudinal follow-ups are suggested to explore actual causal relationships.

wang y.-n., shyu y.-i.l., chen m.-c. & yang p.-s. (2011) Reconciling work and family caregiving among adult-child family caregivers of older people with dementia: effects on role strain and depressive symptoms. Journal of Advanced Nursing67(4), 829–840. Abstract Aims. This paper is a report of a study that examined the effects of work demands, including employment status, work inflexibility and difficulty reconciling work and family caregiving, on role strain and depressive symptoms of adult-child family caregivers of older people with dementia. Background. Family caregivers also employed for pay are known to be affected by work demands, i.e. excessive workload and time pressures. However, few studies have shown how these work demands and reconciliation between work and family caregiving influence caregivers’ role strain and depressive symptoms. Method. For this cross-sectional study, secondary data were analysed for 119 adult-child family caregivers of older people with dementia in Taiwan using hierarchical multiple regression. Results. After adjusting for demographic characteristics, resources and role demands overload, family caregivers with full-time jobs (β = 0·25, P

Toxic epidermal necrolysis (TEN) is a rare condition with potentially high mortality and involves severe exfoliative disease of the skin and mucous membranes induced by drugs. The reported fatality of TEN varies widely from 20% to 60%. The technique for TEN wound coverage described in this article involves the use of various dressings. Patients and methods Nine women with histologically confirmed TEN (>30% total body surface area, TBSA) were treated at our burn intensive care unit. All patients received hydrotherapy and wounds were covered with Aquacel® Ag and Vaseline gauzes onlay. Following this, elastic cotton bandage was wrapped around the dressing. The dressing was changed and the wound evaluated twice a week. Efficacy was established by the wound achieving ≥95% re-epithelialisation of the study area. Results The mean age was 60.1 years (range from 7 to 88 years). The percentage of body surface area affected by epidermal slough ranged from 30% to 85% TBSA, with a mean of 51%. One patient expired due to severe sepsis on day 3. Eight patients achieved over 95% wound healing. All wounds healed well without the need for skin grafting. However, two of them expired on day 14 and day 20 because of pneumonia and retention of carbon dioxide, respectively. The average duration to achieve 95% wound healing was 10.4 days in eight cases (range from 7 to 14 days). No adverse reactions were noted. Conclusion Aquacel® Ag dressing can be easily removed during hydrotherapy. The wound pain is reduced. By changing the dressing just twice a week, we were able to evaluate the wound directly, decrease the odour and increase the quality of life of the patients. In addition, lower frequency of dressing changes decreases the manpower requirements and is cost effective. Use of Aquacel® Ag with Vaseline gauze is a good alternative for the management of TEN wounds.

Aims and objectives. To explore the process of development of collaborative relationship between family caregivers of institutionalized elders with dementia and nursing home staff in Taiwan. Background. Evidence suggests that family members are continuously involved in the lives of loved ones and have not given up their roles as caregivers after the institutionalization of a family member. Little is known, however, about how family caregivers develop a collaborative relationship with nursing home staff, particularly in Asian countries. Design and methods. Grounded theory methodology was used. Data were collected via interviews and observations from 11 family caregivers of patients who were suffering from dementia and living in an institution for persons with dementia in northern Taiwan. Data were analysed by constant comparative analysis. Results. Findings revealed that ‘institutional social penetration’ was the process most used by family caregivers to achieve an harmonious collaborative relationship with the nursing home staff. Institutional social penetration is a dynamic process, which includes three components: self-disclosure, evaluation of care and penetration strategies. Family caregivers, who had developed a ‘socially penetrating’ relationship with the nursing home staff, were more likely to disclose information in more breadth and depth, to receive positive care evaluations and to adopt multiple effective penetration strategies. Conclusions. Institutional social penetration between family caregivers and nursing home staff can sensitize healthcare providers to meet the family's needs during the placement of their loved one and provide a basis for developing intervention strategies. Relevance to clinical practice. Findings of this study may help healthcare providers to understand the ways in which collaborative relationships develop between the families of elders with dementia and nursing home staff. Interventions can be developed to facilitate self-disclosure of both the family members and nursing home staff through timely feedback and familiarising family caregivers with different penetration strategies.

ESTs were used to screen for differential gene expression in a high-grade cell line (MGH-U1) and in a premalignant cell line (MGH-U4). Immunohistochemistry and real-time reverse transcription-polymerase chain reaction were used to validate the degree of EST expression and the prognostic value of ESTs.Results: Apoferritin H subunit (FTH1 protein) exhibited increased expression in high-grade bladder carcinoma compared with that seen in low-grade carcinoma. Immunohistochemistry and real-time reverse transcription-polymerase chain reaction both supported the higher expression of FTH1 in high-grade urothelial carcinoma.Conclusion: ESTs are useful for detecting the FTH1 protein, which predicts the prognosis of patients with bladder carcinoma.Keywords: expression sequence tag, transitional cell carcinoma, FTH1
