    Purpose: Patients with advanced stage IIIB or stage IV non-small cell lung carcinoma are typically treated with initial platinum-based chemotherapy. A variety of factors (eg, performance status, gender, age, histology, weight loss, and smoking history) are generally accepted as predictors of overall survival. Because uncontrolled pulmonary disease constitutes a major cause of death in these patients, we hypothesized that clinical and radiographic factors related to intrathoracic disease at diagnosis may be prognostically significant in addition to conventional factors. The results have implications regarding the selection of patients for whom palliative thoracic radiation therapy may be of most benefit. Methods and Materials: We conducted a pooled analysis of 189 patients enrolled at a single institution into 9 prospective phase II and III clinical trials involving first-line, platinum-based chemotherapy. Baseline clinical and radiographic characteristics before trial enrollment were analyzed as possible predictors for subsequent overall survival. To assess the relationship between anatomic location and volume of disease within the thorax and its effect on survival, the pre-enrollment computed tomography images were also analyzed by contouring central and peripheral intrapulmonary disease. Results: On univariate survival analysis, multiple pulmonary-related factors were significantly associated with worse overall survival, including pulmonary symptoms at presentation (P=.0046), total volume of intrathoracic disease (P=.0006), and evidence of obstruction of major bronchi or vessels on prechemotherapy computed tomography (P<.0001). When partitioned into central and peripheral volumes, central (P<.0001) but not peripheral (P=.74) disease was associated with worse survival. On multivariate analysis with known factors, pulmonary symptoms (hazard ratio, 1.46; P=.042), central disease volume (hazard ratio, 1.47; P=.042), and bronchial/vascular compression (hazard ratio, 1

    Full Text Available INTRODUCTION Radiotherapy is the standard treatment in locally advanced (IIB-IVA and early inoperable cases. The current standard of practice with curable intent is concurrent chemoradiation in which intracavitary brachytherapy is an integral component of radiotherapy. This study aims at assessing the efficacy of HDR ICBT (High-dose rate intracavitary brachytherapy in terms local response, normal tissue reactions, and feasibility. METHODS AND MATERIALS A total of 20 patients of stage IIIB cancer of the uterine cervix were enrolled in the study and were planned to receive concurrent chemotherapy weekly along with EBRT (external beam radiotherapy to a dose of 50 Gy/25 Fr. Suitability for ICBT was assessed at 40 Gy/20 Fr. 6/20 patients were suitable at 40 Gy and received HDR ICBT with a dose of 5.5 Gy to point A in 4 sessions (5.5 Gy/4 Fr. The remaining 14/20 patients completed 50 Gy and received HDR ICBT with a dose of 6 Gy to point A in 3 sessions (6 Gy/3 Fr. RESULTS A total of 66 intracavitary applications were done and only one application required dose modification due to high bladder dose, the pelvic control rate was 85% (17/20. 10% (2/20 had stable disease and 5% (1/20 had progressive disease at one year of follow up. When toxicity was considered only 15% developed grade I and grade II rectal complications. Patient compliance and acceptability was 100%. Patients were very comfortable with the short treatment time as compared with patients on LDR ICBT (low-dose rate intracavitary brachytherapy treatment interviewed during the same period. CONCLUSION This study proves that HDR brachytherapy is efficacious and feasible in carcinoma of cervix stage IIIB. It also proves that good dose distribution can be achieved with HDR intracavitary facility by the use of dose optimization. The short treatment time in HDR ICBT makes it possible to maintain this optimised dose distribution throughout the treatment providing a gain in the therapeutic ratio and

    The emission limits for diesel locomotives inside the European Union are included within the scope of Directive 97/68/EC, which is sometimes referred to as the ''non-road directive''. The pollutants limited by it are NO{sub x}, particulates, CO and HCs. The aim, through the directive, is to reduce railway emissions by a factor of ten by the year 2020. The EU stage IIIB standard is due to take effect on 1 January 2012. This envisages a further drastic reduction in limit values compared with EU stage IIIA, which is applicable today. For diesel locomotives, EU stage IIIA only came into force as recently as 2009. The manufacturers of engines and locomotives are thus having to face up to the huge challenge of getting the technologies needed for EU stage IIIB ready for the production line within a period of only three years. MTU has succeeded in developing engines for diesel locomotives that comply with the EU stage IIIB emission standard, which appreciably lower emissions compared with engines satisfying EU stage IIIA, thanks to the incorporation of the most modern technologies available, and has even gone as far as preparing them for the EU stage IV, the next one to come into force.

    The aim was to determine the long-term prognosis in patients with stage IIIb-IVa squamous cell carcinoma of the cervix who were treated with intra-arterial neoadjuvant chemotherapy (NAC), and to analyze factors related to prognostic value. The authors assessed the disease-free survival of 21 patients with FIGO stage IIIb-IVa squamous cell carcinoma of the cervix treated with intra-arterial NAC followed by irradiation therapy. Before chemotherapy, five factors (age, clinical stage, histologic type, parametrial involvement and serum level of SCC) were evaluated for their correlation with disease-free survival. Univariate Cox's proportional hazard model also demonstrated that age was a significant prognostic factor as a continuous variable. Intra-arterial NAC thus appeared to be effective in treating older patients with stage IIIb-IVa squamous cell carcinoma of the cervix

    Purpose: To report the long-term outcome after radiotherapy with curative intent for Stage IIIB and IVA carcinoma of the cervix. Methods and Materials: We retrospectively reviewed 91 patients treated with radiotherapy with curative intent at University of Florida between January 1980 and December 2003 for Stage IIIB (84 patients) or IVA (7 patients) carcinoma of the cervix. Results: The median follow-up of the surviving patients was 8.8 years. The 5- and 10-year estimates of local control, regional control, locoregional control, relapse-free survival, and overall survival were 53% and 53%, 55% and 47%, 34% and 29%, 30% and 26%, and 29% and 21%, respectively. Ninety percent of the recurrences occurred within 2 years of treatment. Of these, 60% of all failures were local, 29% were regional, and 11% were distant failures alone. Also, 17% of the failures were in the paraaortic nodes with no evidence of failure in the pelvis. Univariate and multivariate analyses were conducted with the endpoint of relapse-free or overall survival. No factor was statistically significant. Complications from therapy were scored using the Radiation Therapy Oncology Group grading system; the overall severe late complication rate was 13% (Grade 3-5). Conclusion: This series is one of the most mature of published reports. With long-term follow-up, approximately one-third of patients with Stage IIIB or IVA carcinoma of the cervix were cured, with a 13% complication rate

    Purpose: There are two criteria for the diagnosis of Stage IIIB cervical cancer in the FIGO staging system: tumor fixation to the pelvic side wall and/or the presence of hydronephrosis due to tumor. However, we often encounter hydronephrosis without tumor fixed to the pelvic side wall or the level of ureteral obstruction not corresponding to the main tumor mass in the pelvis. The clinical implication of these phenomena remains unclear. We investigated the Stage IIIB population treated at the Mallinckrodt Institute of Radiology and hypothesized that, if hydronephrosis presents without tumor fixation to the pelvic side wall or if the level of ureteral obstruction is above the main pelvic tumor mass, it most likely resulted from external compression of ureter(s) by enlarged lymph nodes and, consequently, a worse outcome is expected. Methods and Materials: From 1959 to 1989, there were 297 patients with Stage IIIB cervical cancer who received definitive radiation therapy at the Mallinckrodt Institute of Radiology and were assessable for the presence of hydronephrosis and the level of ureteral obstruction. There were 281 patients who presented with tumor fixed to the pelvic side wall, and 62 of them were associated with concurrent hydronephrosis. An additional 16 patients presented with hydronephrosis without tumor fixation to the pelvic side wall. Among these 78 documented cases of hydronephrosis, the level of ureteral obstruction was above the true pelvis in 39 patients, and below the true pelvis in the other 39. Radiation therapy was individualized according to tumor extension and configuration; para-aortic lymph nodes were not routinely treated except in patients with clinical evidence of nodal metastasis. Results: The progression-free survival (PFS) at 5 years was 35% in 62 patients with hydronephrosis and tumor fixed to the pelvic side wall vs. 43% in 213 patients with tumor fixed to the pelvic side wall only (p 0.12). However, PFS at 5 years decreased to 23% in

    Approximately one third of patients with non-small cell lung cancer have unresectable stage IIIA or stage IIIB disease, and appropriate patients are candidates for chemoradiotherapy with curative intent. The optimal treatment paradigm is currently undefined. Concurrent chemoradiotherapy, compared with sequential chemotherapy and thoracic radiation therapy (TRT), results in superior overall survival outcomes as a result of better locoregional control. Recent trials have revealed efficacy for newer chemotherapy combinations similar to that of older chemotherapy combinations with concurrent TRT and a lower rate of some toxicities. Ongoing phase III trials will determine the roles of cisplatin and pemetrexed concurrent with TRT in patients with nonsquamous histology, cetuximab, and the L-BLP25 vaccine. It is unlikely that bevacizumab will have a role in stage III disease because of its toxicity. Erlotinib, gefitinib, and crizotinib have not been evaluated in stage III patients selected based on molecular characteristics. The preliminary results of a phase III trial that compared conventionally fractionated standard-dose TRT (60 Gy) with high-dose TRT (74 Gy) revealed an inferior survival outcome among patients assigned to the high-dose arm. Hyperfractionation was investigated previously with promising results, but adoption has been limited because of logistical considerations. More recent trials have investigated hypofractionated TRT in chemoradiotherapy. Advances in tumor targeting and radiation treatment planning have made this approach more feasible and reduced the risk for normal tissue toxicity. Adaptive radiotherapy uses changes in tumor volume to adjust the TRT treatment plan during therapy, and trials using this strategy are ongoing. Ongoing trials with proton therapy will provide initial efficacy and safety data.

    From 1976 through 1989, 46 patients with stage IIIB non-small cell lung cancer (NSCLC) without malignant effusion were treated with definitive radiation therapy (RT) at Gunma University Hospital. All patients were treated with 10 MV x-rays using antero posterior parallel opposed fields. The total dose ranged from 60 Gy to 70 Gy (mean dose; 66 Gy) with once daily standard fractionation. The actuarial two and five-year survival rates of the entire group were 22% and 10% respectively with a median survival time (MST) of 10 months. The survival of 18 patients with stage N0-2 disease was significantly better than the 28 patients with stage N3 disease (MST 21 versus 9 months; p<0.05). There were no significant differences in survival based on age and sex. However, there was a borderline difference in survival rates between patients with a performance status of 0-1 and those with status of 2-3 (p=0.06). Three patients with squamous cell carcinoma were alive after 5 years and were without disease progression. No patients with non-squamous cell carcinoma were free of disease after 5 years. These results provide support for the use of definitive RT to manage those patients with limited stage IIIB squamous cell carcinoma not extending to N3 stage. (author)

    To evaluate the efficacy and safety of Icotinib - an orally administered, highly potent selective inhibitor of epidermal growth factor receptor (EGFR) and its active mutations, in the treatment of patients with advanced non-small cell lung cancer (NSCLC). A total of 101 patients with stage IIIb/IV NSCLC were treated with 125 mg Icotinib three times a day until disease progression or intolerable toxicity. Response rate was evaluated using response evaluation criteria in solid tumors and progression-free survival (PFS) was collected. The overall response rate (ORR) and disease control rate (DCR) were 37.6% (38/101) and 79.2% (80/101), respectively. The median PFS was 6.5 months. Multivariate analysis showed that female gender (P= 0.048, 95% confidence interval [CI] 1.010-6.016) and occurrence of rash (P= 0.002, 95% CI 1.667-9.809) were the independent predictive factors for ORR, while a performance status (PS) score of 0-1 (P= 0.001, 95% CI 0.024-0.402) and rash (P= 0.042, 95% CI 1.089-76.557) were the independent predictive factors for DCR. In addition, PS scores of 0-1 (P Icotinib were rash (35.6%) and diarrhea (17.8%), which was tolerable. Treatment of stage IIIb/IV NSCLC patients with Icotinib was effective and tolerable, specifically in patients with EGFR mutation.

    Full Text Available Introduction : The aim of the present study was to evaluate the profile of VEGF-C gene expression in particular stages of cervical cancer (IB-IIIB and to estimate the correlation between VEGF-C mRNA quantity profile and clinical stage. Material and methods : Material for molecular analysis consisted of cervical cancer tissue specimens collected from 38 women (10, 15, 13 cases were classified as IB, IIB and IIIB, respectively. The control group was composed of normal cervical tissues collected from 10 women who underwent hysterectomy for non-oncological reasons. The number of VEGF-C mRNA copies in particular groups was estimated by the reverse transcription quantitative polymerase chain reaction (RT-qPCR method. Results: In the control group the average number of mRNA copies was 134 ± 36 (median: 106, in a group with stage IB it was 16 077 ± 7090 (median: 580, for stage IIB – 35 019 ± 8945 (median: 40 870. The highest number of mRNA VEGF-C copies was derived in a group of patients with cervical cancer of stage IIIB. The average quantity was 56 155 ± 12 470, whereas median 55 981. A statistically significantly higher level of VEGF-C gene expression was disclosed in cervical cancer specimens with stage IIB and IIIB than in the control group. In stage IIIB, the VEGF-C gene expression was significantly higher than in specimens derived from individuals in stage IB. Conclusions : In squamous cell carcinoma of the uterine cervix of stage IB-IIIB genes involved in lymphangio­genesis, especially VEGF-C , are expressed, which expression increases as the clinical stage of cervical cancer is higher.

    Purpose: To define patient, tumor, and treatment factors that influence the outcome of patients with FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix. Materials and Methods: The hospital and radiotherapy records of 1007 consecutive patients treated between 1960 and 1989 for FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix were reviewed retrospectively. All patients were treated with radiation therapy (RT) either with curative intent (903 patients) or to palliate symptoms (104 patients). Patients who were selected for palliative treatment usually had a combination of adverse characteristics including massive tumor with bilateral pelvic wall fixation, hydronephrosis, bulky adenopathy, pathologic evidence of extrapelvic disease, and poor performance status. 64 (7%) of 903 patients failed to complete planned curative RT either because of progressive disease, complications, or poor compliance. Of 903 patients treated with curative intent, 319 (35%) were treated with external beam radiotherapy (EBRT) alone and 586 (65%) were treated with a combination of EBRT and intracavitary irradiation (ICRT). EBRT was usually delivered using 18-25 MV photons and ICRT was administered with Fletcher-Suit-Delclos applicators. Treatment philosophies evolved during the study period with greater emphasis placed on EBRT between 1966 and 1979 (52% treated with EBRT alone) compared with the other study years (15% treated with EBRT alone). 206 patients received investigational treatments including neutrons (69 pts), hyperbaric oxygen (66 pts), concurrent chemotherapy (29 pts), or neoadjuvant chemotherapy (42 pts). 875 patients have been followed until death. Median follow up for surviving patients is 171 months with only 9 surviving patients followed for 10%, or hgb < 10 gm% before treatment or at any time during radiotherapy. DSS was significantly better for patients whose treatment included ICRT (43% vs 21%; P< 0.0001). Also, patients who received

    Purpose: Brazil has one of the highest incidence of carcinoma of the cervix in the world. Half of the patients have advanced stages at the diagnosis. Due to this large number of patients we decided to conduct a prospective pilot study to investigate the tolerance to and survival rate with hyperfractionated external radiotherapy only in patients with Stage IIIB carcinoma of the uterine cervix. Methods and Materials: Between January 1991 and December 1993, 23 patients underwent hyperfractionated external beam radiotherapy without brachytherapy. All cases were biopsy proven squamous cell carcinoma of cervix clinically Staged as IIIB (FIGO). Hyperfractionation (HFX) was given with 1.2 Gy doses, twice daily at 6-h interval, 5 days/week, to the whole pelvis up to 72 Gy within 30 working days. Complications were evaluated by an adaptation of the RTOG Radiation Morbidity Scoring Table graded as 1 = none/mild; 2 = moderate, and 3 = severe. Results: Follow-up ranged from 27 to 50 months (median 40 months) on the 9 to 23 living patients at the time of the analysis in December 1995. There was no severe acute toxicity, but moderate acute reaction was high: 74%. The commonest site of complication was the intestine where severe late toxicity occurred in 2 of 23 (9%). Overall survival rate at 27 months was 48% and at 40 months was 43%. Discussion: There is little information in literature about HFX in carcinoma of the cervix. This is the third published study about it and the one that gave the highest total dose with external HFX of 60 x 1.2 Gy = 72 Gy. Theoretically, through the linear quadratic formula this schedule of HFX would be equivalent to 30 x 2 Gy = 60 Gy of standard fractionation, both treatments given in 30 working days. HFX schedules must be tested to establish their safety. Present results suggest being possible to further increase the total dose in the pelvis with hyperfractionated irradiation

    Objective: to compare survival and toxicity of three different treatments for stage IIIB cervix cancer: low-dose-rate (LDR), high-dose-rate (HDR) brachytherapy and association of HDR and chemotherapy. Methods: between 1985 and 2005, 230 patients with FIGO stage IIIB squamous cell carcinoma of the uterine cervix received 4-field pelvic teletherapy at doses between 40 and 50.4 Gy, with a different complementation in each group. The LDRB group, with 42 patients, received one or two insertions of LDR, with Cesium-137, in a total dose of 80 to 100Gy at point A. The HDR group, 155 patients received HDR in 4 weekly 7 Gy fractions and 9 Gy to 14.4 Gy applied to the involved parametria. The CHT group, 33 patients, were given the same treatment as the HDR group and received 5 or 6 weekly cycles of cisplatin, 40 mg per m2. Results: the five-year progression-free survival (PFS) was 60% for the HDR group and 45% for the LDR group, and the two-year PFS for the CHT group was 65% (p = 0.02). The five-year Overall Survival (OS) was 65% for the HDR group and 49% for the LDR group. The two-year OS was 86% for the CHT group (p 0.02). Rectum toxicity grade II was 7% for the LDR group, 4% for the HDR group and 7% for the CHT group that had one case of rectum toxicity grade IV. Conclusion: patients that received HDR had better OS and PFS. The Chemotherapy-HDR association showed no benefit when compared to HDR only. Toxicity rates showed no difference between the three groups. (author)

    Full Text Available Abstract Background A frequent manifestation of advanced lung cancer is malnutrition, timely identification and treatment of which can lead to improved patient outcomes. Bioelectrical impedance analysis (BIA is an easy-to-use and non-invasive technique to evaluate changes in body composition and nutritional status. We investigated the prognostic role of BIA-derived phase angle in advanced non-small cell lung cancer (NSCLC. Methods A case series of 165 stages IIIB and IV NSCLC patients treated at our center. The Kaplan Meier method was used to calculate survival. Cox proportional hazard models were constructed to evaluate the prognostic effect of phase angle, independent of stage at diagnosis and prior treatment history. Results 93 were males and 72 females. 61 had stage IIIB disease at diagnosis while 104 had stage IV. The median phase angle was 5.3 degrees (range = 2.9 – 8. Patients with phase angle 5.3 had 12.4 months (95% CI: 10.5 to 18.7; n = 84; (p = 0.02. After adjusting for age, stage at diagnosis and prior treatment history we found that every one degree increase in phase angle was associated with a relative risk of 0.79 (95% CI: 0.64 to 0.97, P = 0.02. Conclusion We found BIA-derived phase angle to be an independent prognostic indicator in patients with stage IIIB and IV NSCLC. Nutritional interventions targeted at improving phase angle could potentially lead to an improved survival in patients with advanced NSCLC.

    Background: comprehensive literature on cervical cancer demonstrates, even today, the need for optimization of the timing of external-beam radiotherapy (EBRT) and high-dose-rate brachytherapy (HDR-BT) in the treatment of stage IIA/B-IIIB cervical carcinoma. Patients and methods: 210 patients with carcinoma of the cervix were treated in the Municipal Center of Oncoradiology between January 1991 and December 1996 (FIGO IIA: n = 10, FIGO IIB: n = 113, and FIGO IIIB: n = 87). Two regimens were compared: sequential radiation therapy (SRT) with 4 x 8 Gy HDR-BT to point A followed by EBRT, and continuous radiation therapy (CRT) in which 5 x 6 Gy HDR-BT to point A, one session per week, was integrated into the EBRT. A total dose of 68-70 Gy to point A and 52-54 Gy to point B was given in EBRT with SRT, five fractions per week were applied. Four fractions per week were applied in CRT, i.e., no EBRT was performed on the day of HDR-BT. Total doses to points A and B were identical in both regimens. Overall treatment time (OTT) amounted to 56 days for SRT and 35 days for CRT. Median follow-up time was 3.4 (2.5-4.2) years. Results: progression-free 5-year-survival (PFS) was 71% in the CRT and 56% in the SRT group. Nevertheless, this difference was not statistically significant (p = 1.00), and the same was found in a subgroup analysis of the different tumor stages, showing, however, an unequivocal trend. Late bladder and rectal injuries occurred in 13% and 25%, respectively. Late rectal injuries were significantly more frequent with SRT than CRT (35 patients in the SRT and 18 patients in the CRT group; p = 0.037). This was due to the higher doses per fraction of HDR-BT in the SRT group. No difference was found regarding late bladder injuries (p = 0.837). Conclusion: for the patients included in this study, no advantage has been found so far in using CRT, i.e., shortening the OTT by weekly integration of HDR-BT into EBRT. Nevertheless, an obvious trend exists. The dose of 8 Gy per

    Background and purpose: To evaluate the prognostic significance of response to external beam radiation (EBRT) in predicting the clinical outcomes in stage IIIB cancer cervix and to find out factors affecting response to EBRT. Patients and methods: This retrospective study included 556 patients of cancer cervix stage IIIB treated between 1996 and 2001 with EBRT (46 Gy/23fx/4.5 weeks) followed by intracavitary radiotherapy (ICRT). At the end of EBRT, response to EBRT was grouped as 'no gross residual tumor'(NRT) or 'gross residual tumor'(GRT). Results: Follow up ranged from 2 to 93 months with a median of 36 months. Median dose to point A was 81 Gy. At the end of EBRT, 393 patients (70.7%) attained NRT response. NRT responders had significantly better 5 year pelvic control, disease free survival (DFS) and overall survival (OS) than those who had a GRT response (75.6 vs. 54.6%; 60.6 vs. 31.9% and 62.6 vs. 33.7%, respectively; all P values <0.0001). Apart from response to EBRT, overall treatment time also has emerged as an independent factor to affect all clinical outcomes in multivariate analysis but age had significant impact on pelvic control only. Age was the only factor, which significantly influenced the response to EBRT in univariate as well as multivariate analysis (P=<0.001, OR=1.973, 95% C.I. 1.357-2.868). Patients with age more than 50 years had more NRT response (77%) than patients with age less than 50 years (63.8%). Conclusions: Patients who attain NRT response to EBRT will have an impressive long term pelvic control, DFS and OS in stage IIIB cancer cervix. Older patients (≥50 years) attain significantly higher NRT rates than younger patients

    FDG PET/CT is an excellent tool to detect melanoma metastases and also allows quantification of FDG uptake using standardized uptake value (SUV). The aim of this study was to prospectively investigate the potential prognostic value of SUV for disease-free survival (DFS) and disease-specific survival (DSS) for patients with stage IIIB melanoma. From November 2003 to March 2008, all consecutive patients were included in the present study. Inclusion criteria were: palpable, histology- or cytology-proven lymph node metastases of melanoma, and referred to the University Medical Centre Groningen for FDG PET and CT examination. Patients without distant metastases were evaluated. Multivariable survival analysis was performed to determine whether SUV was associated with DFS and DSS (Cox proportional hazard analysis). In 80 patients (without distant metastases, 65 %) SUV could be measured. Overall 5-year DFS was 41 % (95% CI 26-56 %) and 24 % (95% CI 12-38 %) in patients with a low and high SUVmean (p = 0.02), respectively. Overall 5-year DSS was 48 % (95% CI 31-62 %) and 30 % (95% CI 17-45 %) in patients with a low and high SUVmean (p = 0.04), respectively. In the multivariable analysis, SUVmean was associated with DFS (hazard ratio 1.7; p = 0.048), but was not associated with DSS (hazard ratio 1.6; p = 0.1). The number of positive nodes, extranodal growth and gender were also associated with survival. FDG uptake in clinically overt nodal melanoma metastases is inversely associated with DFS. Univariate analysis showed an association with DSS. However, after adjustment for potential confounders this association was no longer significant. If these findings are confirmed in larger studies, SUVmean could potentially be used (in addition to the number of positive nodes, tumour size and extranodal growth) as a factor in deciding on adjuvant systemic treatment.

    In a prospective study by the Gynecologic Oncology Group (GOG), 104 evaluable patients with cervical squamous cell carcinoma Stages IIIB and IVA were randomly assigned to treatment with hydroxyurea or placebo in combination with radiation. There were no deaths resulting from the treatment. Hematologic toxicity was more common and more severe in patients who received hydroxyurea. Response was evaluated in terms of complete tumor regression, duration of progression-free interval, and survival probability. By all those parameters the response was significantly better in the groups of patients receiving hydroxyurea

    Real-world data on treatment patterns/outcomes in patients with advanced melanoma, while scarce, are useful for health technology assessments that govern patient access in many countries. We collected retrospective data on treatment patterns among patients in France, Germany and the UK with Stage IIIB/IIIC melanoma with macroscopic lymph node involvement, whose primary melanoma and regional lymph node metastases had been completely resected. Patients ≥18 years were diagnosed between 1 January 2009 and 31 December 2011. Data were obtained from patients' medical records and a patient survey. Forty-nine centres provided data on 558 patients: 53.6% had Stage IIIB disease; 58.2% were of working age (<65 years), 22.5% reported a change in employment status due to melanoma, 8% were on long-term sick leave; and 35.1% were deceased over the study period. Overall median distant metastases-free survival was 23.4 months and median disease-free survival was 13.3 months. Hospitalisation frequency increased during distant metastatic/terminal disease phases. Adjuvant therapy was received by 7.0% (14/199) of patients in France, 2.6% (5/195) in the UK, and 33.5% (55/164) in Germany. Low-dose interferon was used more frequently than other regimens. High-dose interferon was associated with discontinuation in 28.6% and dose delay/reduction in 33.3% of patients. Rapid disease progression combined with increased use of healthcare resources in later phases of disease result in a high burden-of-illness for patients and healthcare providers. The use of adjuvant interferon therapy varies considerably in this population in the countries studied, highlighting the need for improved treatments for melanoma. © 2017 John Wiley & Sons Ltd.

    Full Text Available Background and Objectives: Non-small-cell lung cancer (NSCLC represents approximately 80% of all lung cancers. Unfortunately, at their time of diagnosis, most patients have advanced to unresectable disease with a very poor prognosis. The oriental herbal medicine HangAm-Plus (HAP has been developed for antitumor purposes, and several previous studies have reported its therapeutic effects. In this study, the efficacy of HAP was evaluated as a third-line treatment for advanced-stage IIIb/IV NSCLC. Methods: The study involved six patients treated at the East- West Cancer Center (EWCC from April 2010 to October 2011. Inoperable advanced-stage IIIb/IV NSCLC patients received 3,000 or 6,000 mg of HAP on a daily basis over a 12-week period. Computed tomography (CT scans were obtained from the patients at the time of the initial administration and after 12 weeks of treatment. We observed and analyzed the patients overall survival (OS and progression-free survival (PFS. Results: Of the six patients, three expired during the study, and the three remaining patients were alive as of October 31, 2011. The OS ranged from 234 to 512 days, with a median survival of 397 days and a one-year survival rate of 66.7%. In the 12-week-interval chest CT assessment, three patients showed stable disease (SD, and the other three showed progressive disease (PD. The PFS of patients ranged from 88 to 512 days, the median PFS being 96 days. Longer OS and PFS were correlated with SD. Although not directly comparable, the OS and the PFS of this study were greater than those of the docetaxel or the best supportive care group in other studies. Conclusion: HAP may prolong the OS and the PFS of inoperable stage IIIb/IV NSCLC patients without significant adverse effects. In the future, more controlled clinical trials with larger samples from multi-centers should be conducted to evaluate the efficacy and the safety of HAP.

    Full Text Available Vulvar cancer is a rare carcinoma constituting only 4% of gynecologic malignancies and 0.6% of female cancers. Most chemotherapy regimens have been created from extrapolation from anal and cervical cancer research. Advanced stages have the worst prognosis and oftentimes invasive surgical procedures are needed to cure disease with high recurrence rates. Case. A 50 yo G2P2 presented for a 2 cm mass in her right labia. The patient underwent a partial radical vulvectomy and bilateral superficial and deep inguinal lymph node dissection. Bilateral inguinal lymph nodes were positive for residual disease. The patient underwent whole pelvic radiation with cisplatin as a radiosensitizer. The primary tumor was epidermal growth factor receptor (EGFR positive and cetuximab, a monoclonal antibody to EGFR, was added. The patient underwent seven cycles of chemotherapy including cisplatin and cetuximab with adjuvant radiation therapy to the pelvis. She currently is without evidence of disease recurrence since completing treatment 4 years ago. Conclusion. One previous case report showed short-term palliative success of five months for recurrent, metastatic vulvar cancer. This case suggests that cetuximab could possibly be used in initial management of patients with advanced stages of vulvar cancer to improve prognosis.

    Purpose: External irradiation followed by intracavitary therapy (EBIC) has been considered the standard treatment for stage III-B cancer of the uterine cervix. For different reasons, some patients are not suited for intracavitary therapy (ICT), and the treatment may be given entirely by external beam irradiation alone (EBRTA). The purpose of our study is to discuss treatment results and complications for patients undergoing EBIC or EBRTA. Methods and Materials: A retrospective study was carried out on 202 eligible patients with stage III-B cancer of the uterine cervix admitted for radiotherapy from 1980-1997. Ninety-three patients were able to receive EBIC (50 Gy, 8 MV RX whole pelvis followed by one session of 38-45 Gy ICT to point A). The remaining received EBRTA (50-70 Gy for 5-9 or more weeks). Median follow-up procedure was 18.5 months (range: 4-182) for all patients and 26 months (range 4-147) for the patients at risk. Results: The most frequent reason for precluding ICT was large residual tumor volume (32.1%). Ten-year overall survival rates, relapse free survival, and pelvic failure rate for the EBIC and EBRTA patients were, respectively, 22.5% x 15.6% (p = 0.0087), 23.5% x 14.8% (p = 0.005), and 51.6% x 68.8% (p = 0.005). However, when the same comparisons were performed with EBIC patients x EBRTA patients receiving a high dose schedule (60 Gy/6-8 wk to 70 Gy/7-9 wk), the results of the EBIC group remained higher, but the differences became insignificant: respectively, 22.5% x 18.9% (p = 0.17), 23.5% x 15.3% (p = 0.052), and 51.6% x 60.0% (p = 0.10). The distribution of complications was similar in both groups. Conclusions: We found that EBIC was the best treatment modality in our patients with stage III-B cancer of the uterine cervix, whereas for patients who were not candidates for ICT, EBRTA with a high dose schedule appears to be an efficient and safe alternative

    Purpose/Objective: To compare the results between HDR and LDR brachytherapy in the treatment of stage IIIB cervix cancer with radiation therapy alone through a prospective and randomized trial. Materials and Methods: From September 1992 to December 1993, 65 patients with stage IIIB cervical cancer were randomized to one of the following treatment schedule according to the brachytherapy used to complement the dose of external beam radiotherapy (EBRT): 1 - High dose rate (HDR) - 36 patients - 4 weekly insertions of 6,0 Gy at point A 2 - Low dose rate (LDR) - 29 patients - 2 insertions two weeks apart of 17,5 Gy at point A The External Beam radiotherapy was performed through a Linac 4MV, in box arrangement for whole pelvis and in AP-PA fields for parametrial complementation of dose. The dose at the whole pelvis was 45 Gy in 25 fractions of 1,8 Gy and the parametrial dose was 16 Gy. The brachytherapy was realized with Fletcher colpostats and intrauterine tandem, in both arms. The HDR brachytherapy was realized through a Micro-Selectron device, working with Iridium-192 with initial activity of 10 Ci and started ten days after the beginning of EBRT. The total treatment time was shortened in two weeks for this group. The LDR brachytherapy started only after the end of EBRT. Results: With the minimum follow up of 24 months and medium of 31 months, the disease free survival was 50% among the 36 patients in HDR group and 47,8% among the 29 patients in LDR group. Local failures occurred in 50% and 52,8% respectively. Grade I and II complications were restricted to rectites and cistites and the incidence of them was 8,3% for HDR group and 13% for LDR group. Until the time of evaluation there were no grade III complications in any group. Conclusions: Although the number of patients is small and the time of follow up still short, these preliminary results suggest that the HDR brachytherapy has an equivalent efficiency in local control as the LDR in the treatment of stage IIIB

    Purpose/Objective: To determine the efficacy of HDR versus LDR brachytherapy for Stage IIIB cervical cancer patients. Material and Methods: Forty-four HDR patients were retrospectively compared to 51 LDR patients treated at the same institution from 1977 to 1988 (LDR) and from 1989 to 1995 (HDR). A tumor burden score (TBS) of 2-9 was calculated for both groups of patients to assess volume of disease (2-4 low tumor burden, 5-9 high tumor burden). LDR and HDR patients received 60 Gy to the whole pelvis at 1.7 Gy/Fx. The majority of LDR patients were treated after completion of external beam radiation (EBR) with one 25 Gy implant to Point A (55 cGy/h). The HDR patients were treated with 4-5 HDR fractions of 3.7 Gy to 5.8 Gy/Fx for an LDR equivalence of 20-25 Gy (median dose/Fx 4.3 Gy, median insertion number 5). Clinical endpoints were calculated actuarially with significance determined by the log rank test and the relative risk (RR). Results: The median follow-up for the HDR and LDR groups was 1.8 and 5 years, respectively. Pelvic control and survival was better in the LDR group than the HDR group, 51%, 73%, 32%, 44% (p = 0.004, RR = 0.4), with grade III and above RTOG complications of 19% and 15%, respectively. The median age and performance status were similar between the two groups; however, a TBS score ≥7 was present in 23% of the HDR patients and in 9% of the LDR patients. Pelvic control in the HDR group was 58% with a TBS ≤4, and 17% with a TBS >4 (p = 0.01, RR = 0.4). The median EBR dose at the first HDR insertion was 31 Gy while all the LDR patients received 60 Gy before the insertion. Pelvic control rates in Table 1 indicate a trend towards improved outcome within the HDR group and same TBS if more external beam radiation was given prior to the first HDR insertion. Pelvic control was also higher within the HDR group when Point A received a BED Gy 10≥100 versus <100: 62%, 40%, respectively (RR 0.6). Conclusion: These retrospective results of HDR versus

    There is limited data on the pattern of care for locally advanced, clinical (c) IIIB non-small cell lung cancer (NSCLC) in the TNM-7 staging era. The primary aim of this study was to investigate national patterns of care and outcomes in the Netherlands, with a secondary focus on the use of surgery. Data from patients treated for TNM-7 cIIIB NSCLC between 2010 and 2014, was extracted from the Netherlands Cancer Registry (NCR). Survival data was obtained from the automated Civil Registry. 43.762 patients with NSCLC were recorded in the NCR during this 5-year period, with cIIIB accounting for 10% (n=4.401). Clinical N2 (37%) and N3 (63%) nodal involvement was pathologically confirmed in 50.8%. The use of endobronchial ultrasound (EBUS) increased with time from 9% to 29% (pNetherlands, CRT is the most frequent treatment for cIIIB NSCLC in the TNM-7 era. The use of surgery is limited. Accurate staging requires specific attention and the scarce use of radical treatment in elderly patients merits further evaluation. Copyright © 2017 Elsevier B.V. All rights reserved.

    We evaluated the impact of neoadjuvant chemoradiotherapy (NACRT) with radio-enhancing S-1 for locally advanced gastric cancer. Patients who had a gastric cancer infiltrating into other organs (T4) or with bulky N2 were enrolled in this study. They received oral S-1 (65 mg/m 2 /day) administration and 50 Gy radiotherapy followed by radical surgery. In 12 subjects (male:female ratio, 7:5; mean age, 70.0 years), 10 (83.3%) completed NACRT and 12 (100%) underwent curative resection. Histopathological efficacy (≥Grade 1b) and down staging were observed 6 patients (75.0%) and 5 (62.5%), respectively, in 8 T4 patients. The efficacy was ≥Grade 2 in all 4 patients with bulky N2. No extra-nodal invasion was noted. In this series 1-and 3-year survival rates were 90.9% and 60.6%, respectively, during a mean observation period of 18.6 months. This procedure is applicable even to hemorrhaging patients. Outstanding antineoplastic effects are expected in locally advanced gastric cancer. (author)

    Purpose: This study was performed to assess the smoking habits and changes in the cigarette smoking habits of patients prior to, at the time of and after the diagnosis of unresectable stage IIIA/IIIB non-small cell lung cancer. Methods: Patients with the diagnosis of unresectable stage IIIA/IIIB non-small cell lung cancer who had agreed to enter a phase III North Central Cancer Treatment Group Trial comparing twice daily thoracic radiation therapy (TRT) given with chemotherapy to once daily TRT given with chemotherapy were asked to fill out a questionnaire regarding their past and present cigarette smoking habits. This questionnaire included information regarding the number of years of smoking, number of packs of cigarettes smoked per day and the time frame of smoking history. Subsequently, patients were given questionnaires to assess changes in smoking history at the halfway point of treatment, and during follow-up visits. Results: Of the 140 patients who were entered on the above noted trial, 132 filled out baseline questionnaires and were the subject of this study. Of these 132 patients, 126 (95%) had either smoked cigarettes in the past or smoked at the time of study entry. The median pack years of smoking. (years of smoking x packs per day) was 43 with a range of 3-169 pack years. Of the 126 patients with a smoking history, 124 provided information regarding the status of their smoking at the time of entry on the study: 89 (72%) claimed to have quit smoking and, 35 (28%) reported that they continued to smoke an average of one pack per day. Of the 89 patients who had quit smoking, roughly one third had quit within the month before study entry and 45% had quit during the 8 month period prior to entry on the study. Of the 35 patients who continued to smoke at the time of entry on the study, 21 indicated that they stopped smoking during the period following randomization. Hence 10% of the original 140 patients entered on study continued to smoke an average of one

    Full Text Available Abstract Background Cancer stem cell model suggested that tumor progression is driven by the overpopulation of cancer stem cells and eradicating or inhibiting the symmetric division of cancer stem cells would become the most important therapeutic strategy. However, clinical evidence for this hypothesis is still scarce. To evaluate the overpopulation hypothesis of cancer stem cells the association of percentage of CD133+ tumor cells with clinicopathological parameters in colon cancer was investigated since CD133 is a putative cancer stem cell marker shared by multiple solid tumors. Patients and methods Tumor tissues matched with adjacent normal tissues were collected from 104 stage IIIB colon cancer patients who were subject to radical resection between January, 1999 to July, 2003 in this center. The CD133 expression was examined with immunohistochemical staining. The correlation of the percentage of CD133+ cell with clinicopathological parameters and patients' 5-year survival was analyzed. Results The CD133+ cells were infrequent and heterogeneous distribution in the cancer tissue. Staining of CD133 was localized not only on the glandular-luminal surface of cancer cells but also on the invasive budding and the poorly differentiated tumors with ductal structures. Both univariate and multivariate survival analysis revealed that the percentage of CD133+ cancer cells and the invasive depth of tumor were independently prognostic. The patients with a lower percentage of CD133+ cancer cells (less than 5% were strongly associated with a higher 5-year survival rate than those with a higher percentage of CD133+ cancer cells (greater than or equal to 55%. Additionally, no correlation was obtained between the percentage of CD133+ cancer cells and the other clinicopathological parameters including gender, age, site of primary mass, pathologic types, grades, and invasive depth. Conclusion The fact that a higher percentage CD133+ cells were strongly associated

    Purpose: To assess disease response along the parametrial space according to tumor morphology in patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIB and IIIB cervical cancer at the time of image-guided adaptive brachytherapy. Methods and Materials: Patients with FIGO stage IIB and IIIB cervical cancer registered as of November 2013 in the EMBRACE study were evaluated. Tumors were stratified according to morphologic subtype on magnetic resonance imaging (expansive and infiltrative), and the characteristics of those subtypes were analyzed. Parametrial involvement at diagnosis and at brachytherapy was evaluated, and the response to chemo-radiotherapy was classified as good, moderate, or poor. The response grade was compared between the 2 groups and analyzed with regard to tumor volumes, and dosimetric parameters. Results: A total of 452 patients were evaluated, of whom 186 had expansive growth type and 266 had infiltrative morphology. Patients with infiltrative tumors had more extensive disease, as indicated by a higher rate of FIGO stage IIIB disease, as well as radiologic evidence of extension into the distal parametrial space and to the pelvic side wall on magnetic resonance imaging. Cervical necrosis was more common in the infiltrative group. Good response was more common in the expansive group (34% vs 24%; P=.02), and poor response was more common in the infiltrative group (11% and 19%; P=.02). Mean gross tumor volume at diagnosis was equal in both groups (51.7 cm{sup 3}). The high-risk clinical target volume was larger in infiltrative tumors (37.9 cm{sup 3} vs 33.3 cm{sup 3}, P=.005). The mean high-risk clinical target volume D{sub 90} was slightly higher in expansive tumors (92.7 Gy and 89.4 Gy, P<.001). Conclusion: Infiltrative tumors are more advanced at presentation and respond less favorably to chemo-radiotherapy when compared with expansive tumors that are more or less equivalent in size. The use of image

    Neoadjuvant chemotherapy (NAC) and concurrent chemoradiotherapy (CCR) have been used to treat advanced squamous cell carcinoma of the uterine cervix. While the effectiveness of these therapies should be evaluated by a prospective randomized control study, no such study had ever been performed at the National Shikoku Cancer Center Hospital. For this reason, the authors assessed the results of radiotherapy after introduction of RALS (remote-controlled afterloading system) for patients with Stage IIIb squamous cell carcinoma of the uterine cervix and establish historical controls. The subjects were 95 patients (median age: 68 years) who had been treated at this hospital between 1983 and 1993. Twelve patients with PS4, severe complications, and active double cancer, received palliative external irradiation alone to the pelvis and 1 received palliative intracavitary received irradiation alone. The other 82 patients had external irradiation to the pelvis and intracavitary irradiation as curative irradiation. Thus, palliative irradiation and curative irradiation were performed in 13 cases and 82 cases, respectively. The overall survival rate (OAS), disease-specific survival rate (DDS), and disease-free survival rate (DFS) at 5 years in the palliative irradiation group were 7.7%, 16.8%, and 0%, respectively. In the curative irradiation group, OAS, DDS, and DFS were 56.1%, 65.9%, and 61.9%, respectively. Comparisons between the two groups showed significant differences each of the survival rates, and the outcome in the palliative irradiation group was very poor. Risk factors for recurrence were investigated, by comparing DFS among the 82 curatively irradiated cases, but no independent risk factors were identified by multivariate analysis. Exclusive of the patients with PS4, severe complications, active double cancer, and palliative irradiation, 62 patients were defined as historical controls. The survival rates of 62 patients were significantly better than those of the

    Purpose/Objective: To demonstrate feasibility and efficacy of induction chemotherapy followed by concomitant daily irradiation and carboplatine in the treatment of stage IIIB NSCLC patients. Materials and Methods : Were eligible previously untreated patients with histological y proven stage IIIB NSCLC, aged ≤ 75 years, WHO performance status (PS) ≤ 2, neutrophil count ≥ 2000 and platelets ≥ 150,000, and with no renal or hepatic insufficiency. Patients with large tumor volume which could not be irradiated, were excluded from this phase II study. Induction chemotherapy (CT) consisted of navelbine (NVB) and cisplatin (CDDP) administered over a 8 week period. NVB 30 mg/m 2 was given on weeks 1, 2, 4, 5, 6, 8 and 9; NVB 15 mg/m 2 on weeks 3 and 7; CDDP 120 mg/m 2 was given on weeks 1, 5 and 9. Patients free of distant progression after induction CT received megavoltage radiation (66 Gy, 2 Gy/fraction) along with daily CBDCA (15 mg/m 2 ) given 2 to 4 hours before irradiation. Adjuvant NVB-CDDP chemotherapy (2 cycles) was administered in patients still progression-free. Evaluation was performed at the end of induction CT (week 10) and 3 months after the end of irradiation. The Kaplan-Meier method was used to estimate survival rate with time at risk starting the first day of induction CT. Results : From February 1994 to January 1996, 111 patients were enrolled in 8 centers of whom 76 were eligible for analysis at March 1, 1996. Initial characteristics were : male/female ratio (68(8)), mean age 59 (39 to 76), PS 0 : 40%, PS 1 : 49%, PS 2 : 11%, squamous carcinoma 67%. Observed to theoretical dose ratios of NVB and CDDP as induction CT were 83% and 86%, respectively. Hematological grade 3-4 toxicity was observed in 79% of patients; other grade 3-4 toxicities were nausea in 21%, diarrhea in 3%, alopecia in 2% and sepsis in 5% of patients. Seven (9%) patients died before first evaluation. After induction CT, 3 patients were in complete remission (CR), 35 in partial

    The intratumoral infiltration of T cells, especially memory T cells, is associated with a favorable prognosis in early colorectal cancers. However, the mechanism underlying this process remains elusive. This study examined whether high-mobility group box 1 (HMGB1), a damage-associated molecular pattern (DAMP) molecule, is involved in the infiltration of T cells and disease progression in locally advanced colon cancer. Seventy-two cases of pathologically-confirmed specimens were obtained from patients with stage IIIB (T3N1M0) colon cancer who underwent radical resection between January 1999 and May 2002 at the Cancer Center of Sun Yat-Sen University. The density of tumor-infiltrating lymphocytes (TILs) within the tumor tissue and the expression of HMGB1 in the cancer cells were examined via immunohistochemical analysis. The phenotype of CD45RO+ cells was confirmed using a flow cytometric assay. The association between HMGB1 expression, the density of TILs, and the 5-year survival rate were analyzed. The density of CD45RO+ T cells within the tumor was independently prognostic, although a higher density of CD3+ T cells was also associated with a favorable prognosis. More importantly, the expression of HMGB1 was observed in both the nucleus and the cytoplasm (co-expression pattern) in a subset of colon cancer tissues, whereas nuclear-only expression of HMGB1 (nuclear expression pattern) existed in most of the cancer tissues and normal mucosa. The co-expression pattern of HMGB1 in colon cancer cells was inversely associated with the infiltration of both CD3+ and CD45RO+ T cells and 5-year survival rates. This study revealed that the co-expression of HMGB1 is inversely associated with the infiltration of CD45RO+ T cells and prognosis in patients with stage IIIB colon cancer, indicating that the distribution patterns of HMGB1 might contribute to the progression of colon cancer via modulation of the local immune response

    Purpose: To evaluate the efficacy and toxicity of concurrent chemoradiotherapy with paclitaxel/cisplatin for Stage IIIB locally advanced non-small-cell lung cancer (NSCLC). Methods and Materials: Radiotherapy was administered to a total dose of 70.2 Gy (daily fraction of 1.8 Gy, 5 days/wk), over an 8-week period, combined with chemotherapy. The chemotherapy consisted of weekly 40 mg/m 2 of paclitaxel plus 20 mg/m 2 of cisplatin for 8 consecutive weeks. All patients received three-dimensional conformal radiotherapy (3D-CRT), based on computed tomography simulated planning after 41.4 Gy. The median follow-up period of survivors was 24 months. Results: Between January 2000 and October 2002, 135 patients with a median age of 60 years were enrolled and analyzed in this prospective trial. The overall response rate was 75% including 2 cases of complete response. The major patterns of failure were local failure and distant metastasis. The 2-year overall and progression-free survival rates were 37% and 18%, respectively. The median overall and progression-free survival times were 17 months and 9 months, respectively. Hematologic toxicity >Grade 2 was observed in 19% of patients and severe non-hematologic toxicity was infrequent. Conclusions: Three-dimensional conformal radiotherapy, combined with paclitaxel and cisplatin chemotherapy, was associated with a satisfactory outcome with manageable toxicity. Further investigations are needed to improve the local control

    Critical care for advanced lung cancer patients is still controversial, and the appropriate method for the selection of patients who may benefit from intensive care unit (ICU) care is not clearly defined. We retrospectively reviewed the medical records of stage IIIB-IV lung cancer patients admitted to the medical ICU of a university hospital in Korea between 2003 and 2011. Of 95 patients, 64 (67%) had Eastern Cooperative Oncology Group (ECOG) performance status (PS)≥2, and 79 (84%) had non-small-cell lung cancer. In total, 28 patients (30%) were newly diagnosed or were receiving first-line treatment, and 22 (23%) were refractory or bedridden. Mechanical ventilation was required in 85 patients (90%), and ICU mortality and hospital mortality were 57 and 78%, respectively. According to a multivariate analysis, a PaO2/FiO2 ratiobedridden patients (n=22) showed significantly poorer overall survival (11.0 vs. 29.0 days, p=0.005). Among 21 patients who were discharged from the hospital, 11 (52%) received further chemotherapy. Certain advanced lung cancer patients may benefit from ICU management. However, refractory patients and patients with a poor PS do not seem to benefit from ICU care. Oncologists should try to discuss palliative care and end-of-life issues in advance to avoid futile care.

    Full Text Available HeadHER1/EGFR is known to play a pivotal role in tumorigenesis and is overexpressed in up to 80% of NSCLCs. The study of an Expanded Access Clinical Program of Erlotinib in NSCLC is a phase IV openlabel, non-randomized, multicenter trial in patients with advanced (inoperable stage IIIb/IV NSCLC who were eligible for treatment with erlotinib but had no access to trial participation. Patients for the study from Bosnia and Herzegovina (B&H were selected from two Clinical centres (Sarajevo and Banja Luka. The aim of study was to evaluated efficacy and tolerability of erlotinib monotherapy in this setting. All patients who received at least one dose of erlotinib and data were entered in the database as of the CRF cut-off date of 14th May 2008 were included in analysis of data (n = 19. This population is defined as the Intent to Treat (ITT population and includes all patients who had at least one dose of erlotinib regardless of whether major protocol violations were incurred. The findings are consistent with the results of the randomized, placebo-controlled BR.21 study. Indicating that erlotinib is an effective option for patients with advanced NSCLC who are unsuitable for, or who have previously failed standard chemotherapy. In B&H group of patients DCR was almost 84%, and PFS was approximately 24,7 weeks (compared with 44% and 9,7 weeks for erlotinib reported in phase III. Almost three quarter of the patients received erlotinib as their second line of therapy. Overall, erlotinib was well tolerated; there were no patients who withdrew due to a treatment-related AE (mainly rash and there were few dose reductions. 24% of patients experienced an SAE (most commonly gastrointestinal (GI disorders.

    Single-agent gemcitabine is a standard of care for elderly patients with advanced non-small cell lung cancer, but novel therapies are needed for this patient population. We performed a noncomparative randomized phase II trial of gemcitabine, erlotinib, or the combination in elderly patients (age ≥70 years) with stage IIIB or IV non-small cell lung cancer. Patients were randomized to arms: A (gemcitabine 1200 mg/m on days 1 and 8 every 21 days), B (erlotinib 150 mg daily), or C (gemcitabine 1000 mg/m on days 1 and 8 every 21 days and erlotinib 100 mg daily). Arms B and C were considered investigational; the primary objective was 6-month progression-free survival. Between March 2006 and May 2010, 146 eligible patients received protocol therapy. The majority of the patients (82%) had stage IV disease, 64% reported adenocarcinoma histology, 90% reported current or previous tobacco use, and 28% had a performance status of 2. The 6-month progression-free survival rate observed in arms A, B, and C was 22% (95% confidence interval [CI] 11-35), 24% (95% CI 13-36), and 25% (95% CI 15-38), respectively; the median overall survival observed was 6.8 months (95% CI 4.8-8.5), 5.8 months (95% CI 3.0-8.3), and 5.6 months (95% CI 3.5-8.4), respectively. The rate of grade ≥3 hematological and nonhematological toxicity observed was similar in all three arms. The best overall health-related quality of life response did not differ between treatment arms. Erlotinib or erlotinib and gemcitabine do not warrant further investigation in an unselected elderly patient population.

    Enzastaurin is an oral serine/threonine kinase inhibitor that targets protein kinase C-beta (PKC-β) and the phosphatidylinositol-3-kinase/AKT pathway. This trial assessed pemetrexed-carboplatin ± enzastaurin to docetaxel-carboplatin in advanced non-small cell lung cancer. Patients with stage IIIB (with pleural effusion) or IV non-small cell lung cancer and performance status 0 or 1 were randomized to one of the three arms: (A) pemetrexed 500 mg/m and carboplatin area under the curve 6 once every 3 weeks for up to 6 cycles with a loading dose of enzastaurin 1125 or 1200 mg followed by 500 mg daily until disease progression, (B) the same regimen of pemetrexed-carboplatin without enzastaurin, or (C) docetaxel 75 mg/m and carboplatin area under the curve 6 once every 3 weeks for up to six cycles. The primary end point was time to disease progression (TTP). Between March 2006 and May 2008, 218 patients were randomized. Median TTP was 4.6 months for pemetrexed-carboplatin-enzastaurin, 6.0 months for pemetrexed-carboplatin, and 4.1 months for docetaxel-carboplatin (differences not significant). Median survival was 7.2 months for pemetrexed-carboplatin-enzastaurin, 12.7 months for pemetrexed-carboplatin, and 9.2 months for docetaxel-carboplatin (log-rank p = 0.05). Compared with the other arms, docetaxel-carboplatin was associated with lower rates of grade 3 thrombocytopenia and anemia but a higher rate of grade 3 or 4 febrile neutropenia. There was no difference in TTP between the three arms, but survival was longer with pemetrexed-carboplatin compared with docetaxel-carboplatin. Enzastaurin did not add to the activity of pemetrexed-carboplatin.

In the randomized, open-label Phase III OPTiM trial (NCT00769704, talimogene laherparepvec significantly improved durable response rate (DRR versus granulocyte-macrophage colony-stimulating factor (GM-CSF in 436 patients with unresectable stage IIIB–IVM1c melanoma. The median overall survival (OS was longer versus GM-CSF in patients with earlier-stage melanoma (IIIB–IVM1a. Here, we report a detailed subgroup analysis of the OPTiM study in patients with IIIB–IVM1a disease. Patients and methods: The patients were randomized (2:1 ratio to intralesional talimogene laherparepvec or subcutaneous GM-CSF and were evaluated for DRR, overall response rate (ORR, OS, safety, benefit–risk and numbers needed to treat. Descriptive statistics were used for subgroup comparisons. Results: Among 249 evaluated patients with stage IIIB–IVM1a melanoma, DRR was higher with talimogene laherparepvec compared with GM-CSF (25.2% versus 1.2%; P<0.0001. ORR was also higher in the talimogene laherparepvec arm (40.5% versus 2.3%; P<0.0001, and 27 patients in the talimogene laherparepvec arm had a complete response, compared with none in GM-CSF-treated patients. The incidence rates of exposure-adjusted adverse events (AE and serious AEs were similar with both treatments. Conclusion

    Purpose: We retrospectively investigated the impact of weight change (WC) during concurrent chemoradiation therapy (C-CRT) on clinical outcomes of stage 3B non-small cell lung cancer (NSCLC) patients. Methods and Materials: A total of 425 patients treated with C-CRT were included. All patients received 60 to 66 Gy of thoracic radiation therapy concurrently with 1 to 3 cycles of platinum-based chemotherapy. Pre- and posttreatment weight measurements on first and last days of C-CRT were used for WC. Patients were divided into 2 groups: group 1 = weight loss (WL); group 2 = weight preservation/gain (WP) for comparative analyses. Results: Following C-CRT, 252 patients (59.3%) experienced WL, while 89 patients (20.9%) and 84 patients (19.8%) showed WP or WG. At median 24.2 months of follow-up, 142 patients (33.4%) were alive (84 WP [48.6%] and 58 WL [23.0%]), and 58 (13.6%) of them were free of disease progression (41 [23.7%] for WP and 17 [6.7%] for WL). Median overall survival (OS), locoregional progression-free survival (LRPFS), progression-free survival (PFS), and distant metastases-free survival (DMFS) for the entire population were 22.8, 14.4, 10.6, and 11.7 months, respectively. Intergroup comparisons between WP and WL cohorts revealed significantly superior OS, LRPFS, PFS, and DMFS in WP patients (P<.05 for each). On multivariate analyses, only WL and advanced T stage were associated with poor prognosis (P<.05). Conclusions: Present results in 425 stage 3B NSCLC patients demonstrated that WL during C-CRT is strongly associated with inferior survival outcomes compared to WP. This emerging finding might be useful by forming an encouraging basis for future investigations in facilitating a way to improve the outcomes of these patients experiencing WL during C-CRT

    The term New York Heart Association (NYHA) class IIIB has been used increasingly in clinical medicine, including as an inclusion criteria for many clinical trials assessing left ventricular assist devices (LVADs). Indeed, NYHA class IIIB is incorporated in the Food and Drug Administration's approved indication for the Heartmate II. However, on review of the medical literature, we found that there is no consensus definition of NYHA class IIIB. Until the ambiguity is resolved, we suggest that this designation not be used in clinical practice or by investigators leading clinical trials assessing therapies which convey substantial risk to patients and therefore require clarity in describing the enrolled patient population. With ongoing improvements in LVADs, this therapy will increasingly be considered in patients less sick than those who require inotropic support, providing urgency to establish a consensus system of classifying such patients who nevertheless fall within the spectrum of advanced heart failure. Herein we propose a modification of the standard NYHA classification system which can be used to fill this void. Copyright © 2012 Elsevier Inc. All rights reserved.

    Purpose The phase III OAM4971g study (METLung) examined the efficacy and safety of onartuzumab plus erlotinib in patients with locally advanced or metastatic non-small-cell lung cancer selected by MET immunohistochemistry whose disease had progressed after treatment with a platinum-based chemotherapy regimen. Patients and Methods Patients were randomly assigned at a one-to-one ratio to receive onartuzumab (15 mg/kg intravenously on day 1 of each 21-day cycle) plus daily oral erlotinib 150 mg or intravenous placebo plus daily oral erlotinib 150 mg. The primary end point was overall survival (OS) in the intent-to-treat population. Secondary end points included median progression-free survival, overall response rate, biomarker analysis, and safety. Results A total of 499 patients were enrolled (onartuzumab, n = 250; placebo, n = 249). Median OS was 6.8 versus 9.1 months for onartuzumab versus placebo (stratified hazard ratio [HR], 1.27; 95% CI, 0.98 to 1.65; P = .067), with a greater number of deaths in the onartuzumab arm (130 [52%] v 114 [46%]). Median progression-free survival was 2.7 versus 2.6 months (stratified HR, 0.99; 95% CI, 0.81 to 1.20; P = .92), and overall response rate was 8.4% and 9.6% for onartuzumab versus placebo, respectively. Exploratory analyses using MET fluorescence in situ hybridization status and gene expression showed no benefit for onartuzumab; patients with EGFR mutations showed a trend toward shorter OS with onartuzumab treatment (HR, 4.68; 95% CI, 0.97 to 22.63). Grade 3 to 5 adverse events were reported by 56.0% and 51.2% of patients, with serious AEs in 33.9% and 30.7%, for experimental versus control arms, respectively. Conclusion Onartuzumab plus erlotinib did not improve clinical outcomes, with shorter OS in the onartuzumab arm, compared with erlotinib in patients with MET-positive non-small-cell lung cancer.

    Combined modality therapy is a standard therapy for patients with unresectable stage III non-small cell lung cancer (NSCLC). Gefitinib is active in advanced NSCLC, and in preclinical models, it potentiates the activity of radiation therapy. We investigate the tolerability of gefitinib in combined modality therapy in combination with three-dimensional thoracic conformal radiation therapy (3-dimensional TCRT). Stage III patients with a good performance status were treated with induction chemotherapy (carboplatin area under the curve [AUC] of 5, irinotecan 100 mg/m(2), and paclitaxel 175 mg/m(2) days 1 and 22) with pegfilgrastim support followed by concurrent chemotherapy (carboplatin AUC 2, and paclitaxel 45 mg/m(2) weekly) and gefitinib 250 mg daily beginning on day 43 with 3-dimensional TCRT to 74 Gy. Between March 2004 and January 2006, 23 patients received treatment on the trial: median age 62 years (range 44-82), 52% female, 61% stage IIIA, 61% performance status 0, 17% > or =5% weight loss, and 91% underwent positron emission tomography staging. Induction chemotherapy with pegfilgrastim support was well tolerated and active (partial response rate, 24%; stable disease, 76%; and early progression, 0%). Twenty-one patients initiated the concurrent chemoradiation, and 20 patients completed therapy to 74 Gy. The primary toxicities of concurrent chemoradiation were grade 3 esophagitis (19.5%) and cardiac arrhythmia (atrial fibrillation) (9.5%). The median progression-free survival and overall survival were 9 months (95% confidence intervals [CI]: 7-13 months) and 16 months (95% CI: 10-20 months), respectively. Treatment with induction chemotherapy and gefitinib concurrent with 3-dimensional TCRT has an acceptable toxicity and tolerability, but the survival results were disappointing.

    The current study was a retrospective questionnaire survey of stage IIIb adenocarcinoma of the uterine cervix treated with high-dose-rate intracavitary brachytherapy combined with external beam radiation therapy in Japan aimed to investigate the optimal dose on the basis of the biological effective dose and prognostic factors. Between 1990 and 2000, 61 patients with stage IIIb adenocarcinoma of the uterine cervix underwent high-dose-rate intracavitary brachytherapy combined with external beam radiation therapy in 19 major hospitals in Japan. This retrospective questionnaire survey was performed by mail including survey charts to be fulfilled by radiation oncologists in these 19 major hospital. Fifty had only adenocarcinoma components and 11 had adenosquamous cell carcinoma components. All patients were treated with high-dose-rate intracavitary brachytherapy combined with external beam radiation therapy. Total biological effective dose (T-BED 10 ) was calculated from the sum of the biological effective doses of the external beam radiation therapy and the intracavitary brachytherapy. Thirty-two patients underwent chemotherapy. The 5-year overall survival rate of all patients was 20.2%. Stratified by total biological effective dose, the 5-year overall survival rate was 0% for T-BED 10 10 between 75 and 100 Gy and 0% for T-BED 10 >110 Gy (P=0.15). Stratified by histopathology, the 5-year overall survival rate was 22.1% for adenocarcinoma and 13.6% for adenosquamous cell carcinoma (P=0.43). Stratified by chemotherapy, the 5-year overall survival rate was 20.3% in patients who received chemotherapy and 20.4% in patients who did not receive chemotherapy (P=0.96). The 5-year overall survival rate of stage IIIb adenocarcinoma of the uterine cervix in this retrospective questionnaire survey was 20.2%. The optimal T-BED 10 and evident prognostic factors were not clear from this questionnaire survey. (author)

    The prognosis of stage III non-small cell lung cancer (NSCLC) can be improved by a combination of radiotherapy (RT) and chemotherapy (CT). In this study, the GOTHA group evaluated the feasibility, tolerance, tumour response, pattern of failure and effect on survival of a combination alternating accelerated hyperfractionated (AH) RT and CT in patients with tumour stage III NSCLC. Toxic effects were leucopenia, nausea and vomiting, mucositis, diarrhoea, alopecia and peripheral neuropathy. Alternating CT and AHRT, as used in this study, were well tolerated and allowed full dose delivery within less than 12 weeks. Initial response was not predictive of survival. The survival curve is encouraging and the 5 year survival is superior to the 5% generally observed with conventionally fractionated radiotherapy. (author).

In this study the results of the advanced stage Freiberg’s disease patients, who were treated with surgery were evaluated. Methods: 12 patients (8 female, 4 male whose pain could not be solved with conservative method and underwent surgery (6 debridement, 3 osteotomy, 3 excision of the metatarsal head were included in this study. Themean age of the patients 19.1 (range 13- 31 and the mean follow-up 30.8(range 25-94 months. According to the Smillie classification 3 patients had type 5, 8 patients had type 4 and 1 patient had type 3 osteonecrosis. The results of the patients were evaluated according to Lesser Metatarsophalangeal-Interphalangeal Scale. Results: According to Lesser MetatarsophalangealInterphalangeal Scale 3 patients (%25 had excellent, 6 patients (%50 had good and 3 patients had poor results were obtained. 2 of 3 patients with poor results were type 5, and 1 patient was type 4 and all three patients underwent joint debridement. Conclusion:The method of surgical treatment of Freiberg disease determined according to the stage of the disease. Debridement alone in the treatment of patients with late stage is not enough, it should be combined with other methods.

    Rhizoctonia solani anastomosis group AG2-2 IIIB is a severe sugar beet and maize pathogen. It causes crown and root rot disease which leads to yield losses world-wide. The soil-borne pathogen is difficult to detect and quantify by conventional methods. We developed a real-time PCR (qPCR) assay for the quantification of genomic DNA of Rhizoctonia solani AG2-2 IIIB based on the ITS region of rDNA genes. The limit of quantification of the assay is 1.8 pg genomic DNA. The amplification efficiency was 96.4. The assay will be helpful in the diagnoses of Rhizoctonia solani infection of sugar beet and maize roots and in the quantification of R. solani AG2-2 IIIB inoculum in plant debris and soil. (author)

    Traditionally, Gustilo Anderson grade IIIb open tibial fractures have been treated by initial wide wound debridement, stabilization of fracture with external fixation, and delayed wound closure. The purpose of this study is to evaluate the clinical and radiological results of staged treatment using negative pressure wound therapy (NPWT) for Gustilo Anderson grade IIIb open tibial fractures. 15 patients with Gustilo Anderson grade IIIb open tibial fractures, treated using staged protocol by a single surgeon between January 2007 and December 2011 were reviewed in this retrospective study. The clinical results were assessed using a Puno scoring system for severe open fractures of the tibia at the last followup. The range of motion (ROM) of the knee and ankle joints and postoperative complication were evaluated at the last followup. The radiographic results were assessed using time to bone union, coronal and sagittal angulations and a shortening at the last followup. The mean score of Puno scoring system was 87.4 (range 67-94). The mean ROM of the knee and ankle joints was 121.3° (range 90°-130°) and 37.7° (range 15°-50°), respectively. Bone union developed in all patients and the mean time to union was 25.3 weeks (range 16-42 weeks). The mean coronal angulation was 2.1° (range 0-4°) and sagittal was 2.7° (range 1-4°). The mean shortening was 4.1 mm (range 0-8 mm). Three patients had partial flap necrosis and 1 patient had total flap necrosis. There was no superficial and deep wound infection. Staged treatment using NPWT decreased the risks of infection and requirement of flap surgeries in Gustilo Anderson grade IIIb open tibial fractures. Therefore, staged treatment using NPWT could be a useful treatment option for Gustilo Anderson grade IIIb open tibial fractures.

The type of nephrolithiasis was determined in 45 cases and etiology in 42. The treatment and evolution of stone disease and patient’s survival were studied.Results: The overall proportion of nephrolithiasis related ESRD was 0.63%. The mean age was 48.4 years. Infection stones (struvite accounted for 40%, calcium stones, 26.67% (primary hyperparathyroidism:15.56%; familial hypercalciuria: 4.44%, unknown etiology: 6.66%, primary hyperoxaluria type 1, 17.78% and uric acid lithiasis in 15.56% of cases. The mean delay of the evolution of the stone renal disease to chronic renal failure was 85.8 months. The feminine gender, obesity and elevated alkaline phosphatases >128 IU/L were significantly correlated with fast evolution of ESRD. The median evolution to ESRD was 12 months. The normal body mass index (BMI, medical treatment of stone and primary hyperoxaluria type 1 were correlated with fast evolution to ESRD. All patients were treated by hemodialysis during a mean evolution of 60 months. Sixteen patients died. The patient's survival rate at 1, 3 and 5 years was 97.6, 92.8 and 69% respectively. Hypocalcemia, cardiopathy and normal calcium-phosphate product were significantly correlated with lower survival rate.Conclusion: Severe forms of nephrolithiasis remain an underestimated cause of

  3. Cardiovascular Disease and Chronic Inflammation in End Stage Kidney Disease

    Full Text Available Background: Chronic Kidney Disease (CKD is one of the most severe diseases worldwide. In patients affected by CKD, a progressive destruction of the nephrons is observed not only in structuralbut also in functional level. Atherosclerosis is a progressive disease of large and medium-sized arteries. It is characterized by the deposition of lipids and fibrous elements and is a common complication of the uremic syndrome because of the coexistence of a wide range of risk factors. High blood pressure, anaemia, insulin resistance, inflammation, high oxidative stress are some of the most common factors that cause cardiovascular disease and atherogenesis in patients suffering from End Stage Kidney Disease (ESRD. At the same time, the inflammatory process constitutes a common element in the apparition and development of CKD. A wide range of possible causes can justify the development of inflammation under uremic conditions. Such causes are oxidative stress, oxidation, coexistentpathological conditions as well as factors that are due to renal clearance techniques. Patients in ESRD and coronary disease usually show increased acute phase products. Pre-inflammatory cytokines, such as IL-6 and TNF-a, and acute phase reactants, such as CRP and fibrinogen, are closely related. The treatment of chronic inflammation in CKD is of high importance for the development ofthe disease as well as for the treatment of cardiovascular morbidity.Conclusions: The treatment factors focus on the use of renin-angiotensic system inhibitors, acetylsalicylic acid, statins and anti-oxidant treatment in order to prevent the action of inflammatorycytokines that have the ability to activate the mechanisms of inflammation.

    Purpose: To define patient, tumor, and treatment factors that influence the outcome of patients with FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix. Methods and Materials: The records of 1,096 patients treated with radiation therapy between 1960 and 1993 for FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix were reviewed retrospectively. Of these, 983 (90%) were treated with curative intent and 113 were treated only to achieve palliation of symptoms. Of 907 patients who completed the intended curative treatment, 641 (71%) were treated with a combination of external beam irradiation (EBRT) and intracavitary irradiation (ICRT) and 266 (29%) were treated with EBRT only. The median duration of treatment for these 907 patients was 51 days. Between 1966 and 1980, only 52% of patients who completed treatment with curative intent received ICRT, compared with 92% of patients treated during 1981-1993, an increase that reflects an evolution in the philosophy of treatment for advanced tumors. In general, the intensity of ICRT correlated inversely with the dose of EBRT to the central pelvis. Median follow-up of surviving patients was 134 months. Results: For 983 patients treated with initial curative intent, disease-specific survival (DSS) was significantly worse for those who were 52 Gy of EBRT to the central pelvis had DSS rates of 27-34%, compared with 53% for patients treated with lower doses of EBRT to the central pelvis and more intensive ICRT (p 52 Gy of EBRT to the central pelvis (57-68%), compared with those who had 48-52 Gy (28%) and those who had ≤ 47 Gy of EBRT to the central pelvis (15%) (p < 0.0001). Outcome was also compared for four time periods during which different treatment policies were in place for patients with Stage IIIB disease. The highest DSS (51%) and lowest actuarial complication rate (17%) were achieved during the most recent period (1981-1993) when modest doses of EBRT were combined with relatively

    As of 2012, diesel locomotives in Europe must comply with the emission requirements laid down in EU Non-Road Mobile Machinery Directive 97 / 68 / EC Stage IIIB. Compared to the Stage IIIA in effect today, this will require a significant reduction of air pollutants. MTU Friedrichshafen GmbH has developed new engines for rail applications based on the 4000 series which will comply with future emissions standards due to optimisation inside the engine and the use of a diesel particulate filter.

    Mucopolysaccharidosis IIIB (MPS IIIB) is a lysosomal storage disorder characterized by severe behavioural disturbances and progressive loss of cognitive and motor function. There is no effective treatment, but behavioural testing is a valuable tool to assess neurodegeneration and the effect of novel therapies in mouse models of disease. Several groups have evaluated behaviour in this model, but the data are inconsistent, often conflicting with patient natural history. We hypothesize that this discrepancy could be due to differences in open field habituation and home cage behaviour. Eight-month-old wild-type and MPS IIIB mice were tested in a 1-h open field test, performed 1.5 h after lights on, and a 24-h home cage behaviour test performed after 24 h of acclimatization. In the 1-h test, MPS IIIB mice were hyperactive, with increased rapid exploratory behaviour and reduced immobility time. No differences in anxiety were seen. Over the course of the test, differences became more pronounced with maximal effects at 1 h. The 24-hour home cage test was less reliable. There was evidence of increased hyperactivity in MPS IIIB mice, however, immobility was also increased, suggesting a level of inconsistency in this test. Performance of open field analysis within 1-2 h after lights on is probably critical to achieving maximal success as MPS IIIB mice have a peak in activity around this time. The open field test effectively identifies hyperactive behaviour in MPS IIIB mice and is a significant tool for evaluating effects of therapy on neurodegeneration. © 2011 The Authors.

    Full Text Available ABSTRACT Purpose The study aims to assess the influence of the stage of chronic kidney disease and glomerular filtration rate on prevalence and degree of erectile dysfunction. Materials and Methods This transversal study, conducted from May 2013 to December 2015, included patients with chronic kidney disease in conservative treatment, stages III/IV/V. Erectile dysfunction was evaluated by the International Index of Erectile Function. Data classically associated with erectile dysfunction were obtained by medical record review. Erectile dysfunction, degree of erectile dysfunction, and other main variables associated with erectile dysfunction were compared between patients with chronic kidney disease on conservative treatment stages III versus IV/V using the Chi-square test. The relationship between score of the International Index of Erectile Dysfunction and glomerular filtration rate was established by Pearson correlation coefficient. Results Two hundred and forty five patients with chronic kidney disease in conservative treatment participated of the study. The prevalence of erectile dysfunction in patients with chronic kidney disease in stages IV/V was greater than in stage III. Glomerular filtration rate positively correlated with score of the International Index of Erectile Dysfunction. Conclusions The study suggests that chronic kidney disease progression (glomerular filtration rate decrease and advance in chronic kidney disease stages worsen erectile function. Hypothetically, diagnosis and treatment of erectile dysfunction may be anticipated with the analysis of chronic kidney disease progression.

    Disease staging involves the assessment of disease severity or progression and is used for treatment selection. In diabetic retinopathy, disease staging using a wide area is more desirable than that using a limited area. We investigated if deep learning artificial intelligence (AI) could be used to grade diabetic retinopathy and determine treatment and prognosis. The retrospective study analyzed 9,939 posterior pole photographs of 2,740 patients with diabetes. Nonmydriatic 45° field color fundus photographs were taken of four fields in each eye annually at Jichi Medical University between May 2011 and June 2015. A modified fully randomly initialized GoogLeNet deep learning neural network was trained on 95% of the photographs using manual modified Davis grading of three additional adjacent photographs. We graded 4,709 of the 9,939 posterior pole fundus photographs using real prognoses. In addition, 95% of the photographs were learned by the modified GoogLeNet. Main outcome measures were prevalence and bias-adjusted Fleiss' kappa (PABAK) of AI staging of the remaining 5% of the photographs. The PABAK to modified Davis grading was 0.64 (accuracy, 81%; correct answer in 402 of 496 photographs). The PABAK to real prognosis grading was 0.37 (accuracy, 96%). We propose a novel AI disease-staging system for grading diabetic retinopathy that involves a retinal area not typically visualized on fundoscopy and another AI that directly suggests treatments and determines prognoses.

    From September 1989 to December 1992, 178 patients with cervix cancer were treated with radiation therapy alone, being 81 stage IIIB patients were randomized according to the number of intracavitary brachytherapy insertion realized after external irradiation. Of these, 34 were treated with two intracavitary insertion (group A) and 47 with one insertion (group B). Among stage IIIB patients, 54 were treated with one intracavitary insertion after external irradiation (group C) and 47 with external irradiation alone as they had no geometrical condition for intracavitary insertion (group D). There were no statistical difference in 50 months disease free survival among patients stage IIB treated with one or two intracavitary insertion, 72,3% and 70.6% respectively (P=0,711). The 50 months disease free survival were better in patients stage IIIB treated with external irradiation followed by one intracavitary insertion, compared with those treated with external irradiation alone, 51,8% and 30,2% respectively (P=0,007). This series suggests that there is no difference in the treatment of stage IIB cervix cancer with one or two intracavitary insertion. Among stage IIIB patients, the worse result of those treated with external irradiation alone was probably due to the unfavorable prognostic factors, as they were excluded for brachytherapy because they showed no geometrical condition for intracavitary insertion and larger tumor volume.

    2016-03-01

    Conclusions: On most behavioral measures, MPS IIIB patients did not differ substantially from MPS IIIA patients over age six, demonstrating autistic features and a Klüver Bucy-like syndrome including lack of fear and poor attention. Delay in onset of behavioral symptoms was associated with later diagnosis in two patients. Lack of fear, poor attention, and autistic-like symptomatology are as characteristic of MPS IIIB as they are of MPS IIIA. A possible difference is that the some behavioral abnormalities develop more quickly in MPS IIIB. If this is so, these patients may become at risk for harm and present a challenge for parenting even earlier than do those with MPS IIIA. In future clinical trials of new treatments, especially with respect to quality of life and patient management, improvement of these behaviors will be an essential goal. Because very young patients were not studied, prospective natural history documentation of the early development of abnormal behaviors in MPS IIIB is needed.

  1. High prevalence of frailty in end-stage renal disease

    This paper provides a survival analysis of End Stage Renal Disease (ESRD) under Kaplan-Meier Estimates and Weibull Distribution. The data were obtained from the records of V. L. MakabaliMemorial Hospital with respect to time t (patient's age), covariates such as developed secondary disease (Pulmonary Congestion and Cardiovascular Disease), gender, and the event of interest: the death of ESRD patients. Survival and hazard rates were estimated using NCSS for Weibull Distribution and SPSS for Kaplan-Meier Estimates. These lead to the same conclusion that hazard rate increases and survival rate decreases of ESRD patient diagnosed with Pulmonary Congestion, Cardiovascular Disease and both diseases with respect to time. It also shows that female patients have a greater risk of death compared to males. The probability risk was given the equation R = 1 — e-H(t) where e-H(t) is the survival function, H(t) the cumulative hazard function which was created using Cox-Regression.

  7. Tendon Interposition and Ligament Reconstruction with ECRL Tendon in the Late Stages of Kienböck’s Disease: A Cadaver Study

    Full Text Available Background. The optimal surgical treatment for Kienböck’s disease with stages IIIB and IV remains controversial. A cadaver study was carried out to evaluate the use of coiled extensor carpi radialis longus tendon for tendon interposition and a strip obtained from the same tendon for ligament reconstruction in the late stages of Kienböck’s disease. Methods. Coiled extensor carpi radialis longus tendon was used to fill the cavity of the excised lunate, and a strip obtained from this tendon was sutured onto itself after passing through the scaphoid and the triquetrum acting as a ligament to preserve proximal row integrity. Biomechanical tests were carried out in order to evaluate this new ligamentous reconstruction. Results. It was biomechanically confirmed that the procedure was effective against axial compression and distributed the upcoming mechanical stress to the distal row. Conclusion. Extensor carpi radialis longus tendon has not been used for tendon interposition and ligament reconstruction in the treatment of this disease before. In view of the biomechanical data, the procedure seems to be effective for the stabilization of scaphoid and carpal bones.

    To evaluate the potential health issues associated with periodontal disease (PD) in dogs, 1004 teeth from 25 dogs were examined. The dogs were randomly selected, aged 2-14 years, and had at least 95% of their teeth at the first PD stage. Significant positive correlations between plaque grade (PG) and gum inflammation, gingival regression, periodontal pocket, age and serum alanine aminotransferase (ALT) activity were identified. In contrast, PG was negatively correlated to total platelet count. Altogether, these findings suggest that prevention and therapy at the first PD stages can have an important impact on the general health condition of dogs. Copyright © 2014 Elsevier Ltd.

    Between April 1969, and December 1974, 216 successive surgically-staged IA-IIIB Hodgkin's disease patients were seen and treated at the Joint Center for Radiation Therapy. Patients with stages IA and IIA disease received mantle and para-aortic-splenic pedicle irradiation alone and have a probability of relapse-free survival of 97 percent and 80 percent, respectively. Patients with stage IIIA disease were treated with total-nodal irradiation (TNI) alone and have a 51 percent relapse-free and 82 percent overall survival. In spite of the high relapse rate in stage IIIA patients, the majority are currently disease-free following retreatment with MOPP chemotherapy. Stage IIB and IIIB patients received either radiation therapy alone or combined with chemotherapy. While the relapse-free survival is similar in stage IIB patients with or without the addition of chemotherapy, combined TNI and MOPP chemotherapy in stage IIIB patients has provided a superior relapse-free survival (74 percent) when compared to patients treated with TNI alone. There have been 3 mantle irradiation-related deaths in 209 patients treated (1.5 percent); in contrast, there have been 6 deaths related to combined-modality treatment in 74 patients at risk (8 percent). We continue to advocate the minimum therapy needed to produce uncomplicated cure. We feel that this is achieved with radiation therapy alone in stages IA and IIA disease without extensive mediastinal involvement and with combined modality therapy in stage IIIB disease. The role of combined modality therapy in place of radiation therapy alone in stage IIB and IIIA disease is less certain

    Dysphagia is a clinically relevant symptom in patients with Parkinson's disease (PD) leading to pronounced reduction in quality of life and other severe complications. Parkinson's disease-related dysphagia may affect the oral and pharyngeal, as well as the esophageal phase of swallowing. To examine the nature and extend of esophageal dysphagia in different stages of PD and their relation to oropharyngeal dysfunction, we examined 65 PD patients (mean age 66.3±9.7 years, mean disease duration 7.9±5.8 years, mean Hoehn & Yahr [H&Y] stage 2.89±0.91) and divided into three groups (early [H&Y I+II; n=21], intermediate [H&Y III; n=25], and advanced stadium [H&Y IV+V; n=19]), using esophageal high-resolution manometry (HRM) to detect esophageal motor disorders. Oropharyngeal impairment was assessed using fiberoptic endoscopic evaluation of swallowing. Major esophageal motor disorders were detected in nearly one third of the PD patients. Minor impairment of the esophageal body was present in 95% of participants and throughout all disease stages with pathological findings especially in peristalsis and intrabolus pressure (IBP). The IBP was found to significantly increase in the advanced stadium. Although dysfunction of the upper and lower esophageal sphincters was observed in individual patients, alterations in these esophageal segments revealed no statistical significance compared with normative data. No clear association was found between the occurrence of oropharyngeal dysphagia and esophageal impairment. Esophageal body impairment in PD is a frequent phenomenon during all disease stages, which possibly reflects α-synucleinopathy in the enteric nervous system. © 2016 John Wiley & Sons Ltd.

    Treatment recommendations for patients with upper abdominal Stage IIIA Hodgkin's (III1A) disease have varied widely. The current study reports on a combined institutional retrospective review of 85 patients with surgically staged III1A Hodgkin's disease. Twenty-two patients received combined modality therapy (CMT), 36 patients were treated initially with total nodal irradiation (TNI), and 27 with mantle and para-aortic radiotherapy (MPA). Patients treated with CMT had an actuarial 8-year freedom from relapse (FFR) of 96% as compared to a FFR of 51% in TNI treated patients (p = 0.002), and a FFR of 54% in MPA treated patients (p = 0.004). Of the 11 relapses in MPA treated patients, 7 had a component of their failure in the untreated pelvic or inguinal nodes. The patients treated with CMT had an 8-year actuarial survival of 100% as compared to 79% in TNI treated patients (p = 0.055) and 78% in patients treated with MPA (p = 0.025). Histology and the number of splenic nodules were the most important prognostic variables. Patients with MC/LD histology and greater than or equal to 5 splenic nodules have a high risk of relapse (10/13) when treated with radiation alone (TNI or MPA). We recommend CMT for this group of patients. Patients with NS/LP histology and 1-4 splenic nodules represent a favorable subset of Stage III1A patients. Only 4/21 patients have relapsed and all 21 patients are currently alive without disease regardless of treatment. We currently feel that patients with Stage III1A Hodgkin's disease with NS/LP histology and splenic disease limited to 1-4 nodules are good candidates for MPA as an alternative to TNI or CMT

    Two treatment policies for the therapy of patients with Stage IIIA Hodgkin's disease are compared. From 1969-1976, 49 newly diagnosed and pathologically staged IIIA patients received total nodal irradiation (TNI) alone (no liver irradiation). Although actuarial survival was 80% at 5 years and 68% at 10 years, actuarial freedom from relapse was only 38% at 5 years. Accordingly, a new treatment policy was instituted in 1976. Patients with either CS IIIA disease, multiple splenic nodules, IIIA with a large mediastinal mass or III 2 , received combined modality therapy (combination chemotherapy and irradiation). All others received TNI. Thirty-six patients have been treated under the new program. The actuarial survival is 90% at 5 years and the relapse-free survival is 87%, suggesting the superiority of this approach. Complications from the treatments are discussed

    Full Text Available The research on staging of pre-symptomatic and prodromal phase of neurological disorders, e.g., Alzheimer's disease (AD, is essential for prevention of dementia. New strategies for AD staging with a focus on early detection, are demanded to optimize potential efficacy of disease-modifying therapies that can halt or slow the disease progression. Recently, neuroimaging are increasingly used as additional research-based markers to detect AD onset and predict conversion of MCI and normal control (NC to AD. Researchers have proposed a variety of neuroimaging biomarkers to characterize the patterns of the pathology of AD and MCI, and suggested that multi-view neuroimaging biomarkers could lead to better performance than single-view biomarkers in AD staging. However, it is still unclear what leads to such synergy and how to preserve or maximize. In an attempt to answer these questions, we proposed a cross-view pattern analysis framework for investigating the synergy between different neuroimaging biomarkers. We quantitatively analyzed 9 types of biomarkers derived from FDG-PET and T1-MRI, and evaluated their performance in a task of classifying AD, MCI and NC subjects obtained from the ADNI baseline cohort. The experiment results showed that these biomarkers could depict the pathology of AD from different perspectives, and output distinct patterns that are significantly associated with the disease progression. Most importantly, we found that these features could be separated into clusters, each depicting a particular aspect; and the inter-cluster features could always achieve better performance than the intra-cluster features in AD staging.

    The purpose of our study was to describe the clinical and radiological manifestations of tuberculosis in patients with end-stage renal disease. The medical records, chest radiographs, and CT scans of 42 patients with tuberculosis among 871 consecutive patients with end-stage renal disease were reviewed. Patterns of initial chest radiographs were categorized as primary, postprimary, miliary, or atypical, according to the predominant radiologic findings. Chest radiographs and CT scans revealed pulmonary tuberculosis in 28 patients and extrapulmonary tuberculosis in 15. The pattern of chest radiographs indicative of pulmonary tuberculosis was primary in 12 cases, postprimary in 11, miliary in one, demonstrated atypical infiltrates in three, and was normal in one. Tuberculosis involved the extrathoracic lymph nodes in six cases, the peritoneum in four, the spine in three, and the bone marrow in two. The primary pattern, seen in 12 patients, manifested as pleural effusion or segmental consolidation, and in ten of the twelve the former was dominant. The radiological pattern of pulmonary tuberculosis in end-stage renal disease is often primary, and extrapulmonary involvement is frequent

    OBJECTIVE: Depression and anxiety significantly affect morbidity in Huntington's disease. Mice. models of Huntington's disease have identified sex differences in mood-like behaviours that vary across disease lifespan, but this interaction has not previously been explored in humans with Huntington......'s disease. However, among certain medical populations, evidence of sex differences in mood across various disease stages has been found, reflecting trends among the general population that women tend to experience anxiety and depression 1.5 to 2 times more than men. The current study examined whether...... disease stage and sex, either separately or as an interaction term, predicted anxiety and depression in Huntington's disease. METHODS: A cross-sectional study of REGISTRY data involving 453 Huntington's disease participants from 12 European countries was undertaken using the Hospital Anxiety...

    Full Text Available ABSTRACT: Intermittent hemodialysis (IHD is a form of renal replacement that is used in veterinary medicine for cases involving drug removal, electrolyte imbalance, acute kidney injury, and chronic kidney disease (CKD. The aim of the present study was to verify the efficacy of IHD in dogs with CKD staged at grade III and to evaluate the effect of IHD on quality of life. Twelve dogs with CKD at stage III met the inclusion criteria and were divided equally into two groups. The control group (n=6 received only clinical treatment and intravenous fluid therapy, and the hemodialysis group (n=6 received clinical and IHD treatments. Blood samples were collected before and after treatments in both groups. We evaluated complications and clinical parameters of IHD every 30 minutes. Hemodialysis decreased serum urea, creatinine, and phosphorus. Despite the evident removal of nitrogen compounds, dialysis treatment did not increase survival time in these patients. The results of this study do not support the early use of dialysis in dogs with chronic kidney disease stage III.

    One hundred twenty-one patients with newly diagnosed, previously untreated Hodgkin disease underwent abdominal and pelvic computed tomographic (CT) scanning and bipedal lymphography. These studies were followed by staging laparotomy, which included biopsy of the liver, retroperitoneal and mesenteric lymph nodes, and splenectomy. Correlation of the results of the imaging studies with the histopathologic diagnoses revealed a small - but significant - increased accuracy of lymphography compared with CT in assessing the retroperitoneal lymph nodes. The theoretical advantages of CT scanning in detecting lymphomatous deposits in lymph nodes about the celiac axis and the mesentery, or in the liver and spleen, were not confirmed.

    Subjective emotional experience is thought to rely on a large cortical-subcortical network including orbitofrontal and cingulate frontostriatal circuits together with the mesolimbic dopaminergic system that modulates their activity. Parkinson's disease (PD) provides a model for exploring this issue. By using an original emotion induction procedure, the present study examined to what extent subjective experience of emotion of PD patients at different stages of the disease was modulated by emotion in the same way as healthy individuals. A battery of film excerpts was used to elicit different emotional feelings (happiness, anger, fear, sadness, disgust, and neutral) in 15 newly diagnosed PD patients, 18 patients with advanced PD and 15 matched controls. The newly diagnosed patients were examined in two conditions: "on" and "off" dopaminergic medication. Participants reported the intensity of their emotional feelings on a scale consisting of 10 emotional categories. Results indicated that PD patients at different stages of the disease did not significantly differ from the controls in the self-reported emotional experience to the presented film excerpts. Moreover, analyses conducted within the newly diagnosed PD group (on-dopa vs. off-dopa conditions) indicated that the patients' emotional reactivity to the presented film excerpts was not significantly modulated by dopaminergic medication. These results thus question the possible role of dopaminergic pathways in subjective emotional experience, at least in this sample and in the context of emotion induction.

    This literature review of recent clinical and experimental studies describes the role of oxidative stress in the multifactorial and interdisciplinary pathogenesis of non-inflammatory chronic pelvic pain syndrome IIIB (CPPS-IIIB) in men. The authors outline general biological nature of oxidative stress and its mechanisms. More detailed information is presented on cytokine-mediated chronic subclinical inflammation, one of the key mechanisms of oxidative stress, which is currently being actively studied. It is shown that the imbalance between pro- and anti-inflammatory cytokines observed in patients with CPPS-IIIB can explain some features of the clinical course (in particular, the characteristics of the pain syndrome) and the progression of this disease. In this regard, cytokine profiling of prostatic secretion can provide valuable diagnostic, prognostic and monitoring information in the management of this category of patients. Recently published evidence has demonstrated the essential role of the cytokine-mediated chronic inflammatory response as a mechanism of oxidative stress in the pathogenesis of CPPS-IIIB. Further studies in this area are warranted and in the long term may become a basis for the development of new effective pathogenetic pharmacotherapy of CPPS-IIIB.

    While tendon degeneration has been known to be an important cause of rotator cuff disease, few studies have objectively proven the association of tendon degeneration and rotator cuff disease. The purpose of this study was to investigate changes of tendon degeneration with respect to the stage of rotator cuff disease. A total of 48 patients were included in the study: 12 with tendinopathy, 12 with a partial-thickness tear (pRCT), 12 with a full-thickness tear (fRCT), and 12 as the control. A full-thickness supraspinatus tendon sample was harvested en bloc from the middle portion between the lateral edge and the musculotendinous junction of the tendon using a biopsy punch with a diameter of 3 mm. Harvested samples were evaluated using a semi-quantitative grading scale with 7 parameters after haematoxylin and eosin staining. There was no significant difference in age, gender, symptom duration, and Kellgren-Lawrence grade between the groups except for the global fatty degeneration index. All of the seven parameters were significantly different between the groups and could be categorized as follows: early responders (fibre structure and arrangement), gradual responder (rounding of the nuclei), after-tear responders (cellularity, vascularity, and stainability), and late responder (hyalinization). The total degeneration scores were not significantly different between the control (6.08 ± 1.16) and tendinopathy (6.67 ± 1.83) (n.s.). However, the score of pRCT group (10.42 ± 1.31) was greater than that of tendinopathy (P rotator cuff disease progresses from tendinopathy to pRCT, and then to fRCT. The degree of degeneration of tendinopathy was not different from that of normal but aged tendons, and significant tendon degeneration began from the stage of pRCT. The clinical relevance of the study is that strategies and goals of the treatment for rotator cuff disease should be specific to its stage, in order to prevent disease progression for tendinopathy and pRCT, as

  7. Diabetic nephropathy. Is end-stage renal disease inevitable?

    Science.gov (United States)

    Bogusky, R T

    1983-10-01

    The appearance of proteinuria in an insulin-dependent diabetic patient is an ominous sign. Proteinuria heralds the presence of diabetic nephropathy and early death, or chronic renal failure requiring dialysis or transplantation, in 50% of patients. The pathogenesis of diabetic nephropathy is unknown. Adequate insulin administration is the most important preventive measure. Hypertension, if present, should be aggressively treated to delay progression of renal disease. Good nutrition, prompt treatment of urinary tract infections, and caution in the use of radiocontrast agents are other important preventive measures. Hemodialysis, peritoneal dialysis, and transplantation are options for patients with end-stage renal disease. No matter which is selected, the patient may still have multiple amputations, blindness, congestive heart failure, infections, and uncontrolled glycemia. Advancements are being made, however, that promise a better future for insulin-dependent diabetics.

    Full Text Available Severe forms of chronic kidney disease can lead to a critical, end-stage condition, requiring renal replacement therapy, which may involve a form of dialysis or renal transplantation. Identification and characterization of novel markers and/or targets of therapy that could be applied in these critically ill patients remains the focus of the current research in the field of critical care medicine and has been the objective of our studies for some years past. To this end, we used models of renal vascular disease, Ang II, L-NAME or mice overexpressing renin, treated with AT1 antagonists at different stages of progression, to create cohorts of animals during progression, reversal or escape from therapy. Transcriptomic analysis and comparisons were performed and genes were selected according to the following criteria: a not previously described in the kidney, b highly upregulated during progression and returning to the normal levels during reversal, and c producing proteins that are either circulating or membrane receptors.

    To evaluate whether ceramic workers exposed to silica experience an excess of end stage renal disease. On the basis of a health surveillance programme, a cohort of 2980 male ceramic workers has been enrolled during the period 1974-91 in Civitacastellana, Lazio, Italy. For each worker, employment history, smoking data, and x ray film readings were available. The vital status was ascertained for all cohort members. All 2820 people still alive and resident in the Lazio region as in June 1994 were searched for a match in the regional end stage renal diseases registry, which records (since June, 1994) all patients undergoing dialysis treatment in public and private facilities of the region. Expected numbers of prevalent cases from the cohort were computed by applying the rate of patients on dialysis treatment by the age distribution of the cohort. A total of six cases was detected when 1.87 were expected (observed/expected (O/E) = 3.21; 95% confidence interval (95% CI) 1.17 to 6.98). The excess risk was present among non-smokers (O = 2; O/E = 4.34) and smokers (O = 4; O/E = 2.83), as well as among workers without silicosis (O = 4; O/E = 2.78) and workers with silicosis (O = 2; O/E = 4.54). The risk was higher among subjects with 20 years. These results provide further evidence that exposure to silica dust among ceramic workers is associated with nephrotoxic effects.

    Full Text Available Hypoplastic thumb is the second most common congenital deformity of the thumb. Thumb hypoplasia is characterized by diminished thumb size, metacarpal adduction, metacarpophalangeal joint instability, and thenar muscle hypoplasia. In the literature, different classification types of hypoplastic thumb have been used and different treatment methods described. In this case we presented an alternative palliative treatment method for a ten-year-old patient with modified Blauth's classification type IIIB hypoplastic thumb and one-year follow-up results.

    To assess correlations between the degree of dopaminergic depletion measured using single-photon emission computed tomography (SPECT) and different clinical parameters of disease progression in Parkinson's disease (PD). This retrospective study included 970 consecutive patients undergoing {sup 123}I-ioflupane SPECT scans in our institution between 2003 and 2013, from which we selected a study population of 411 patients according to their clinical diagnosis: 301 patients with PD (69.4 ± 11.0 years, of age, 163 men) and 110 patients with nondegenerative conditions included as controls (72.7 ± 8.0 years of age, 55 men). Comprehensive and operator-independent data analysis included spatial normalization into standard space, estimation of the mean uptake values in the striatum (caudate nucleus + putamen) and voxel-wise correlation between SPECT signal intensity and disease stage as well as disease duration in order to investigate the spatiotemporal pattern of the dopaminergic nigrostriatal degeneration. To compensate for potential interactions between disease stage and disease duration, one parameter was used as nonexplanatory coregressor for the other. Increasing disease stage was associated with an exponential decrease in {sup 123}I-ioflupane uptake (R {sup 2} = 0.1501) particularly in the head of the ipsilateral caudate nucleus (p < 0.0001), whereas increasing disease duration was associated with a linear decrease in {sup 123}I-ioflupane uptake (p < 0.0001; R {sup 2} = 0.1532) particularly in the contralateral anterior putamen (p < 0.0001). We observed two distinct spatiotemporal patterns of posterior to anterior dopaminergic depletion associated with disease stage and disease duration in patients with PD. The developed operator-independent reference database of 411 {sup 123}I-ioflupane SPECT scans can be used for clinical and research applications. (orig.)

    Because of the considerable heterogeneity in breast carcinoma with noninflammatory skin involvement (T4b/Stage IIIB), a revision was proposed of the TNM staging system that would classify these tumors exclusively based on their tumor size and lymph node status. In the current study, the authors evaluated how implementation of this proposal will affect Stage III noninflammatory breast cancer. Two hundred seven patients who were classified with noninflammatory Stage III breast cancer were treated consecutively between 1990 and 1999 at the University Hospital Basel, Switzerland. To assess the extent of T4b/Stage IIIB tumors independent of the clinicopathologic feature of skin involvement, the reclassification was undertaken. Of 68 patients who had nonmetastatic T4b breast cancer, 37 patients (54.4%) had a tumor extent in accordance with Stage I/II and had improved disease-specific survival (DSS) compared with patients who had Stage III breast cancer (P = .008). Excluding those patients from Stage III led to a 17.9% reduction of the number of patients in this group (n = 170 patients). The 10-year DSS declined from 48.5% to 42.9%. Considerable numbers of patients who are classified with noninflammatory Stage IIIB breast cancer show only a limited disease extent. Through a revision of the T4 category, these low-risk patients were excluded from the highest nonmetastatic TNM stage, and overstaging could be avoided. This procedure decreased the degree of heterogeneity of the entire Stage III group and may result in a more precise assessment of this disease entity. Copyright 2006 American Cancer Society.

    Thirty patients with acute cerebrovascular disease were evaluated by both computed tomography (CT) and magnetic resonance (MR) imaging. The 17 patients with cerebral infarction (CI) were evaluated within 24 hours and the 13 with intracerebral hemorrhage (ICH) within 6 hours of the onset of symptoms. All ICHs were detected in T2-weighted images and appeared as perifocal, ring-like areas of high signal intensity. T2-weighted images also demonstrated a ruptured aneurysm and an arteriovenous malformation. In T1-weighted images, all ICHs displayed high signal intensity, which paralleled the CT images and is characteristic of MR imaging with an ultra-low magnetic filed. These findings were obtained as early as 90 minutes from the onset of symptoms. In cases of CI, T2-weighted images obtained 3 - 7 hours after onset demonstrated the pathology more clearly than did CT. This study proved MR imaging useful in the evaluation of both ICH and CI in the acute stage. In addition, it was possible to differentiate ICH from CI in the acute stage by T2-weighted images alone.

    To determine the frequency of endometriosis in general gynecological and infertile women presenting to hospital and to correlate symptomatology and stage of disease. Fifty patients with diagnosis of endometriosis on laparoscopy were included in the study. The degree of pain symptoms was graded according to 1-4 point verbal rating scale designed by Biberoglu and Behrman. Endometriosis was staged according to Revised American Fertility Society (R-AFS) scoring on laparoscopy. Correlation coefficient-Spearman rank order correlation test was applied to analyze data. The frequency of endometriosis in infertile women was 24% (33) and in women with general gynecological complaints, it was 23% (17). There was a significant positive correlation between chronic pelvic pain and R-AFS scoring. Increasing severity of pelvic pain was also positively correlated with presence of endometrioma and complete obliteration of pouch of Douglas. No correlation between dysmenorrhoea and R-AFS scoring could be detected. Dysmenorrhoea was strongly and positively correlated with the presence of superficial implants. Dyspareunia was found to have positive correlation with R-AFS score and also with complete obliteration of pouch of Douglas. The frequency of endometriosis in infertile women was 24% (33) and in women with general gynecological complaints, it was 23% (17). Chronic pelvic pain and dyspareunia had strong positive correlation with R-AFS score while dysmenorrhoea had no such correlation. (author)

    Full Text Available Cardiovascular disease is the main cause of death among patients with end-stage renal disease (ESRD. The present study was undertaken to identify the main cardiovascular diseases and their risk factors in 160 patients with ESRD on hemodialysis (HD in Brazil. Their mean age was 47 ± 39 years. The main risk factors for cardiovascular diseases were arterial hypertension (89.4%, dyslipidemia (78.3%, low high-density lipoprotein levels (84.2% and low physical activity (64.1%. Family history of coronary insufficiency and high low-density lipoprotein levels were significantly associated with coronary artery disease (P = 0.005 and P = 0.029, respectively. Sedentary life style, diabetes mellitus, secondary hyperparathyroidism and hyperglycemia also showed a significant association with the underlying vascular disease (P = 0.017, P = 0.039, P = 0.037 and P = 0.030, respectively. Hypercalcemia, hypertension and black race were factors significantly associated with left ventricular systolic dysfunction (P = 0.01, P = 0.0013 and P = 0.024, respectively. Our study shows that the most prevalent cardiovascular diseases in patients with ESRD were left ventricular hypertrophy, atherosclerotic disease, valvular disease and coronary artery disease. Hypertension and dyslipidemia were the common risk factors associated with cardiovascular diseases. The present study was undertaken to identify the main cardiovascular diseases and their risk factors in 160 patients with ESRD on HD in a single center in Brazil.

  17. End Stage and Chronic Kidney Disease: Associations with Renal Cancer

    International Nuclear Information System (INIS)

    Russo, Paul

    2012-01-01

    There is a well known association between end stage renal disease and the development of kidney cancer in the native kidney of patients requiring renal replacement therapy. There is now emerging evidence that lesser degrees of renal insufficiency (chronic kidney disease, CKD) are also associated with an increased likelihood of cancer in general and kidney cancer in particular. Nephropathological changes are commonly observed in the non-tumor bearing portions of kidney resected at the time of partial and radical nephrectomy (RN). In addition, patients with renal cancer are more likely to have CKD at the time of diagnosis and treatment than the general population. The exact mechanism by which renal insufficiency transforms normal kidney cells into tumor cells is not known. Possible mechanisms include uremic immune inhibition or increased exposure to circulating toxins not adequately cleared by the kidneys. Surgeons managing kidney tumors must have an increased awareness of their patient’s renal functional status as they plan their resection. Kidney sparing approaches, including partial nephrectomy (PN) or active surveillance in older and morbidly ill patients, can prevent CKD or delay the further decline in renal function which is well documented with RN. Despite emerging evidence that PN provides equivalent local tumor control to RN while at the same time preventing CKD, this operation remains under utilized in the United States and abroad. Increased awareness of the bi directional relationship between kidney function and kidney cancer is essential in the contemporary management of kidney cancer.

    End-stage renal disease and dialysis is commonly associated with poor outcomes after joint replacement surgery. The goal of this study was to evaluate postoperative complications in patients with less advanced chronic kidney disease undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA). Patients who underwent THA or TKA between 2004 and 2011 with stage 1, 2, or 3 chronic kidney disease were retrospectively reviewed via an electronic medical record. The authors compared 377 patients who had stage 1 to 2 chronic kidney disease with 402 patients who had stage 3 chronic kidney disease. No significant differences in 90-day readmission or revision rates were found between the stage 1 to 2 and stage 3 patient groups. For patients with stage 3 chronic kidney disease, the overall mortality rate was greater than that in patients with stage 1 to 2 chronic kidney disease. However, when adjusted for comorbid disease, no significant increases were seen in joint infection, readmission, or early revision between patients with stage 1 to 2 chronic kidney disease vs patients with stage 3 chronic kidney disease. The overall incidence of infection was high (3.5%) but far less than reported for patients with end-stage renal disease, dialysis, and kidney transplant. In conclusion, patients with stage 1, 2, or 3 chronic kidney disease may have a higher than expected rate of prosthetic joint infection (3.5%) after total joint arthroplasty. Patients with stage 3 chronic kidney disease are at higher risk for postoperative mortality compared with those with lesser stages of kidney disease. Copyright 2014, SLACK Incorporated.

    Full Text Available Background: Autosomal dominant polycystic kidney disease (ADPKD is a progressive genetic disorder characterized by the development of numerous kidney cysts that result in kidney failure. Little is known regarding the key patient characteristics and utilization of healthcare resources for ADPKD patients along the continuum of disease progression. This observational study was designed to describe the characteristics of ADPKD patients and compare them with those of patients with other chronic kidney diseases. Methods: This retrospective cohort study involved patients with a claim for ADPKD or PKD unspecified from 1/1/2000–2/28/2013 and ≥6 months of previous continuous enrollment (baseline within a large database of administrative claims in the USA. A random sample of chronic kidney disease (CKD patients served as comparators. For a subset of ADPKD patients who had only a diagnosis code of unspecified PKD, abstraction of medical records was undertaken to estimate the proportion of patients who had medical chart-confirmed ADPKD. In patients with linked electronic laboratory data, the estimated glomerular filtration rate was calculated via serum creatinine values to determine CKD stage at baseline and during follow-up. Proportions of patients transitioning to another stage and the mean age at transition were calculated. Results: ADPKD patients were, in general, younger and had fewer physician visits, but had more specific comorbidities at observation start compared with CKD patients. ADPKD patients had a longer time in the milder stages and longer duration before recorded transition to a more severe stage compared with CKD patients. Patients with ADPKD at risk of rapid progression had a shorter time-to-end-stage renal disease than patients with CKD and ADPKD patients not at risk, but stage duration was similar between ADPKD patients at risk and those not at risk. Conclusions: These results suggest that distribution of patients by age at transition

    Hydronephrosis is frequently encountered in advanced stage cervical cancers, and may be associated with mortality. In the present study, we aimed to demonstrate the effect of hydronephrosis on survival in patients with inoperable advanced stage cervical cancer. The study data were acquired by retrospective analysis of the patient records belonging to 165 women with FIGO (International Federation of Gynecology and Obstetrics) stage-IIIB or more advanced cervical cancer, which were not surgical candidates. Parameters including patient age, pathological diagnosis, disease stage, pelvic sidewall extension, presence of hydronephrosis and administration of chemoradiation were analyzed. Further, the effects of these variables on survival were assessed. P values less than 0.05 were considered statistically significant. The distribution of the study patients according to disease stage was as follows: 131 (79.4%) had stage-IIIB, 18 (10.9%) had stage-IVB and 16 (% 9.7) patients had stage-IVA disease. Hydronephrosis was not evident in 91 (55.2%) of these patients, whereas 41 (24.8%) had unilateral and 33 (20%) patients had bilateral hydronephrosis. When compared to mean survival in patients who did not have hydronephrosis, survival was significantly shortened in patients who had bilateral and unilateral hydronephrosis (phydronephrosis (p>0.05). Although patient age, pathological type, pelvic involvement, and chemotherapy treatment rates were similar (p>0.05), radiotherapy requirement rate and disease stage were significantly different among the study groups (pHydronephrosis was found to be a significant predictor of poor survival in patients with advanced stage cervical cancer, irrespective of unilateral or bilateral involvement.While waiting for future studies with larger sample sizes, we believe that the FIGO stages in advanced cervical cancer could further be stratified into subgroups according to presence or absence of hydronephrosis.

    The number of persons receiving renal replacement therapy (RRT) is estimated at more than 2.5 million worldwide, and is growing by 8% annually. Registries in the developing world are not up to standards compared to the United States Renal Data System (USRDS). Herein we examine the causes, progression, and magnitude of end-stage kidney disease (ESKD) over 3 decades in Oman. We examined ESKD data from 1983 to 2013. Data from 1998 to 2013 were obtained through an Information Management System. Data before 2008 were collected from patients' files. A questionnaire based on USRDS form 2728 was completed by nephrologists once a citizen reached ESKD. A total of 4066 forms were completed, with a response rate of 90% (52% male). The mean (SD) age was 50.1 (14.0) years. By 31 December 2013, there were 2386 patients alive on RRT, of whom 1206 were on hemodialysis (50.5%), 1080 were living with a functioning kidney transplant (45.3%), and 100 were receiving peritoneal dialysis (4.2%). The incidence of ESKD on RRT was 21, 75, and 120 per million population in 1983, 2001, and 2013, respectively. Similarly, the prevalence of ESKD was 49, 916, and 2386 in 1983, 2001, and 2013 respectively. Among patients with ESKD on RRT, a progressive rise was seen in diabetic nephropathy, with 5.8%, 32.1%, and 46% in 1983, 2001, and 2013 respectively. The incidence and prevalence of ESKD has increased progressively over last 30 years. This is anticipated to continue at an even higher rate in view of the progressive rise in noncommunicable diseases. Continuous improvement in registries is required to improve capturing of ESKD patients for providing accurate data to health authorities, and enhancing public awareness of the magnitude, future trends, treatments, and outcomes regarding ESKD.

    A limited number of studies have assessed health-related quality of life (HRQoL) in autosomal dominant polycystic kidney disease (ADPKD). Results to date have been conflicting and studies have generally focused on patients with later stages of the disease. This study aimed to assess HRQoL in ADPKD across all stages of the disease, from patients with early chronic kidney disease (CKD) to patients with end-stage renal disease. A study involving cross-sectional patient-reported outcomes and retrospective clinical data was undertaken April-December 2014 in Denmark, Finland, Norway and Sweden. Patients were enrolled into four mutually exclusive stages of the disease: CKD stages 1-3; CKD stages 4-5; transplant recipients; and dialysis patients. Overall HRQoL was generally highest in patients with CKD stages 1-3, followed by transplant recipients, patients with CKD stages 4-5 and patients on dialysis. Progressive disease predominately had an impact on physical health, whereas mental health showed less variation between stages of the disease. A substantial loss in quality of life was observed as patients progressed to CKD stages 4-5. Later stages of ADPKD are associated with reduced physical health. The value of early treatment interventions that can delay progression of the disease should be considered. © The Author 2016. Published by Oxford University Press on behalf of ERA-EDTA.

    Visual impairments are frequent in Parkinson's disease (PD) and impact normal functioning in daily activities. Visual contrast sensitivity is a powerful nonmotor sign for discriminating PD patients from controls. However, it is usually assessed with static visual stimuli. Here we examined the interaction between perception and eye movements in static and dynamic contrast sensitivity tasks in a cohort of mildly impaired, early-stage PD patients. Patients (n = 13) and healthy age-matched controls (n = 12) viewed stimuli of various spatial frequencies (0-8 cyc/deg) and speeds (0°/s, 10°/s, 30°/s) on a computer monitor. Detection thresholds were determined by asking participants to adjust luminance contrast until they could just barely see the stimulus. Eye position was recorded with a video-based eye tracker. Patients' static contrast sensitivity was impaired in the intermediate spatial-frequency range and this impairment correlated with fixational instability. However, dynamic contrast sensitivity and patients' smooth pursuit were relatively normal. An independent component analysis revealed contrast sensitivity profiles differentiating patients and controls. Our study simultaneously assesses perceptual contrast sensitivity and eye movements in PD, revealing a possible link between fixational instability and perceptual deficits. Spatiotemporal contrast sensitivity profiles may represent an easily measurable metric as a component of a broader combined biometric for nonmotor features observed in PD.

    In a multicenter randomized phase II trial of gemcitabine (arm A), erlotinib (arm B), and gemcitabine and erlotinib (arm C), similar progression-free survival (PFS) and overall survival (OS) were observed in all arms. We performed an exploratory, blinded, retrospective analysis of plasma or serum samples collected as part of the trial to investigate the ability of VeriStrat (VS) to predict treatment outcomes. Ninety-eight patients were assessable, and the majority had stage IV disease (81%), adenocarcinoma histology (63%), reported current or previous tobacco use (84%), and 26% had a performance status (PS) of 2. In arm A, patients with VS Good (n = 20) compared with VS Poor status (n = 8) had similar PFS (hazard ratio [HR]: 1.21; p = 0.67) and OS (HR: 0.82; p = 0.64). In arm B, patients with VS Good (n = 26) compared with VS Poor (n = 12) had a statistically significantly superior PFS (HR: 0.33; p = 0.002) and OS (HR: 0.40; p = 0.014). In arm C, patients with VS Good (n = 17) compared with Poor (n = 1 5) had a superior PFS (HR: 0.42; p = 0.027) and a trend toward superior OS (HR: 0.48; p = 0.051). In the multivariate analysis for PFS, VS status was statistically significant (p = 0.011); for OS, VS status (p = 0.017) and PS (p = 0.005) were statistically significant. A statistically significant VS and treatment interaction (gemcitabine versus erlotinib) was observed for PFS and OS. Gemcitabine is the superior treatment for elderly patients with VS Poor status. First-line erlotinib for elderly patients with VS Good status may warrant further investigation.

    Few studies have investigated the relation between dream features and cognition in Parkinson's disease (PD), although vivid dreams, hallucinations and cognitive decline have been proposed as successive steps of a pathological continuum. Our objectives were therefore to characterize the dreams of early stage PD and to study the relation between dream characteristics, cognitive function, motor status, depression, dopaminergic treatment, and the presence of REM sleep behaviour disorder (RBD) and hallucinations. Dreams of 19 male PD patients and 21 matched control subjects were classified according to Hall and van de Castle system. h statistics was used to compare the dream content between patients and controls. We tested the relation between patients' dreams characteristics and cognitive function (Frontal assessment battery (FAB) and Mini-Mental State Examination tests) depression (Beck depression inventory), motor function (UPDRS), dopaminergic treatment, the presence of RBD (according to clinical criteria) and hallucinations, using general linear model statistics. Patients and controls differed only on FAB scores. Relevant differences in the Hall and van de Castle scale were found between patient's dreams and those of the control group, regarding animals, aggression/friendliness, physical aggression, befriender (higher in the patient group) and aggressor and bodily misfortunes (lower in the patient group) features. Cognitive and particularly frontal dysfunction had a significant influence on the frequency of physical aggression and animal related features, while dopaminergic doses, depressive symptoms, hallucinations and RBD did not. We found a pattern of dream alteration characterized by heightened aggressiveness and the presence of animals. These were related to more severe frontal dysfunction, which could be the origin of such changes.

    Full Text Available This study was undertaken to define the prevalence of the upper Gastrointestinal (GI lesions, dyspeptic symptoms, H.pylori infection, and the impact of duration of dialysis on upper GI symptoms and lesions of children with End-stage renal disease. We studied 69 children with ESRD who were under regular hemodialysis therapy in our department. The age of the patients were between 4-18 years (mean: 11.3. 57(82.6% of 69 patients had GI symptoms and 12(17.4% were symptom free, the prevalence of each symptom in 57 symptomatic children was as follows: anorexia 48(84.2%, nausea/vomiting 39 (68.4%, belching/heartburn 20(35%, abdominal distention 15(26.3%, and epigastric pain 8(14%. 65(92.4% of 69 patients with ESRD had pathologic lesions and the most common lesion was gastritis .There was no case of gastric angiodysplasia in our patients. 15(21.7% of 69 patients had H. pylori infection. The prevalence of H.pylori infection in non-uremic children with upper GI symptoms is about 27% in our pediatric gastroenterology department, so there was no significant difference in prevalence of H.pylori infection between uremic and non-uremic children in our study (p value = 0.4735. There was no significant relationship between duration of dialysis and dyspeptic symptoms or upper GI lesions (p values were 0.8775 and 0.7435, respectively. Conclusions: Upper GI disorders are very common in children with ESRD, even when they have no upper GI symptoms, the most common lesion is gastritis. The prevalence of H.pylori infection is not different between children with ESRD and non-uremic children with upper GI symptoms, and duration of hemodialysis therapy has no significant effect on prevalence of GI symptoms and lesions.

    Chronic kidney disease of unknown etiology (CKDU) is endemic among the rural farming communities in several localities in and around the North Central region of Sri Lanka. This is an interstitial type renal disease and typically has an insidious onset and slow progression. This study was conducted to identify the pathological features in the different clinical stages of CKDU. This is a retrospective study of 251 renal biopsies identified to have a primary interstitial disease from regions endemic for CKDU. Pathological features were assessed and graded in relation to the clinical stage. The mean age of those affected by endemic CKDU was 37.3 ± 12.5 years and the male to female ratio was 3.3:1. The predominant feature of stage I disease was mild and moderate interstitial fibrosis; most did not have interstitial inflammation. The typical stage II disease had moderate interstitial fibrosis with or without mild interstitial inflammation. Stage III disease had moderate and severe interstitial fibrosis, moderate interstitial inflammation, tubular atrophy and some glomerulosclerosis. Stage IV disease typically had severe interstitial fibrosis and inflammation, tubular atrophy and glomerulosclerosis. The mean age of patients with stage I disease (27 ± 10.8 years) was significantly lower than those of the other stages. About 79.2%, 55%, 49.1% and 50% in stage I, II, III and IV disease respectively were asymptomatic at the time of biopsy.

    2016-03-01

    The review summarizes recent studies on chronic kidney disease-mineral bone disorders, with a focus on new developments in disease management. The term chronic kidney disease-mineral bone disorder has come to describe an increasingly complex network of alterations in minerals and skeletal disorders that contribute to the significant cardiovascular morbidity and mortality seen in patients with chronic kidney disease and end stage renal disease. Clinical studies continue to suggest associations with clinical outcomes, yet current clinical trials have failed to support causality. Variability in practice exists as current guidelines for management of mineral bone disorders are often based on weak evidence. Recent studies implicate novel pathways for therapeutic intervention in clinical trials. Mineral bone disorders in chronic kidney disease arise from alterations in a number of molecules in an increasingly complex physiological network interconnecting bone and the cardiovascular system. Despite extensive associations with improved outcomes in a number of molecules, clinical trials have yet to prove causality and there is an absence of new therapies available to improve patient outcomes. Additional clinical trials that can incorporate the complexity of mineral bone disorders, and with the ability to intervene on more than one pathway, are needed to advance patient care.

    Addison's disease is a rare disorder in patients with end-stage renal disease (ESRD). In patients, the diagnosis of Addison's disease is difficult in clinical practice because most of the clinical findings of this disease are similar to those of the renal failure. We present a 51-year-old male patient, who underwent hemodialysis therapy for 8 years, diagnosed with Addison's disease after having myalgia, skin hyperpigmentation, weight loss, sweating, and nausea for the past few weeks. The physical examination was completely normal except for muscle weakness, hyperpigmentation on labial mucosa and skin in a patient. The laboratory tests revealed anemia and hypoglycemia. Serum cortisol, adrenocorticotropic hormone (ACTH) levels, and ACTH stimulation test results were consistent with Addison's disease. Adrenal computerized tomography revealed bilateral atrophic glands. Additionally, it was found that elevated serum thyroid stimulating hormone levels and antithyroid peroxidase antibody titer were positive. Our purpose is to emphasize that physicians should be alert to the potential for additional different conditions particularly in terms of adrenal failure in patients with ESRD.

    Hydroxychloroquine sulfate retinopathy can progress after the drug is stopped. It is not clear how this relates to the stage of retinopathy or whether early screening with modern imaging technology can prevent progression and visual loss. To determine the relationship between progression of retinopathy and the severity of disease using objective data from optical coherence tomography and assess the value of early screening for the toxic effects of hydroxychloroquine. Clinical findings in patients with hydroxychloroquine retinopathy were monitored with repeated anatomical and functional examinations for 13 to 40 months after the drug was stopped in a referral practice in a university medical center. Eleven patients participated, with the severity of toxic effects categorized as early (patchy parafoveal damage shown on field or objective testing), moderate (a 50%-100% parafoveal ring of optical coherence tomography thinning but intact retinal pigment epithelium), and severe (visible bull's-eye damage). Visual acuity, white 10-2 visual field pattern density plots, fundus autofluorescence, spectral-density optical coherence tomography cross sections, thickness (from cube diagrams), and ellipsoid zone length. Visual acuity and visual fields showed no consistent change. Fundus autofluorescence showed little or no change except in severe cases in which the bull's-eye damage expanded progressively. Optical coherence tomography cross sections showed little visible change in early and moderate cases but progressive foveal thinning (approximately 7 μm/y) and loss of ellipsoid zone (in the range of 100 μm/y) in severe cases, which was confirmed by quantitative measurements. The measurements also showed some foveal thinning (approximately 4 μm/y) and deepening of parafoveal loss in moderate cases, but the breadth of the ellipsoid zone remained constant in both early and moderate cases. A few cases showed a suggestion of ellipsoid zone improvement. Patients with

    Finding efficient central nervous system (CNS) delivery approaches has been the major challenge facing therapeutic development for treating diseases with global neurological manifestation, such as mucopolysaccharidosis (MPS) IIIB, a lysosomal storage disease, caused by autosomal recessive defect of alpha-N-acetylglucosaminidase (NaGlu). Previously, we developed an approach, intracisternal (i.c.) injection, to deliver recombinant adeno-associated viral (rAAV) vector to the CNS of mice, leading to a widespread periventricular distribution of transduction. In the present study, we delivered rAAV2 vector expressing human NaGlu into the CNS of MPS IIIB mice by an i.c. injection approach, to test its therapeutic efficacy and feasibility for treating the neurological manifestation of the disease. We demonstrated significant functional neurological benefits of a single i.c. vector infusion in adult MPS IIIB mice. The treatment slowed the disease progression by mediating widespread recombinant NaGlu expression in the CNS, resulting in the reduction of brain lysosomal storage pathology, significantly improved cognitive function and prolonged survival. However, persisting motor function deficits suggested that pathology in areas outside the CNS contributes to the MPS IIIB behavioral phenotype. The therapeutic benefit of i.c. rAAV2 delivery was dose-dependent and could be attribute solely to the CNS transduction because the procedure did not lead to detectable transduction in somatic tissues. A single IC rAAV2 gene delivery is functionally beneficial for treating the CNS disease of MPS IIIB in mice. It is immediately clinically translatable, with the potential of improving the quality of life for patients with MPS IIIB.

    To study and summarize the etiology of children patients with chronic kidney disease (CKD) stage 2 to 5 seen in Children's Hospital of Fudan University from Jan. 2004 to Dec. 2013. By complying with the NKF-K/DOQI guidelines, we collected data of 264 cases of children patients with CKD stage 2-5 from Jan. 2004 to Dec. 2013 in the medical record system of Children's Hospital of Fudan University. And we retrospectively analyzed their age and CKD stage at first diagnosis, primary diseases, complications, etc. In the collected 264 cases, 52 cases (19.7%) were diagnosed at stage 2, 67 (25.4%) at stage 3, 52 (19.7%) at stage 4 and 93 (35.2%) at stage 5. For disease causes, 116 cases (43.9%) had congenital anomalies of the kidney and urinary tract (CAKUT), 61 cases (23.1%) had glomerular disease, 15 (5.7%) had hereditary kidney disease, 14 (5.3%) had other diseases and in 58 cases (22.0%) the causes of disease were unknown. In the group with age between 0 and 3.0 and 3.1 and 6.0 years, 57.1% (24 cases) and 60.0% (30 cases) had primary disease with CAKUT. In the group with age older than 10 years, 49.2% (30 cases) had primary disease with glomerular disease and 32.0% (32 cases) with unknown causes. The major cause of CKD stage 2-5 in children in our hospital during the last ten years was CAKUT (43.9%), followed by glomerular disease (23.1%). The primary diseases of CKD were significantly different between the 2 age groups. CAKUT was more common in infants and preschool children while for adolescents, glomerular disease was the major cause.

    Full Text Available Introduction: Diabetes Mellitus (DM is a common chronic disease accompanied by severe complications. It is the leading cause of End-Stage Renal Disease (ESRD requiring management either by haemodialysis (HD or peritoneal dialysis (PD. The chronicity of the disease, and its complications, affects the psychological, family and social life of the patients and their Quality of Life (QoL. Aim: of the present study was to estimate the disease burden of patients with diabetic nephropathy (DN during pre-ESRD and during End-Stage Renal Disease. Methods: A sample of 103 patients with DN treated at the General Hospital of Veria were studied during May and June 2016. The study was conducted using the Dialysis Symptoms Index (DSI for the assessment of Chronic Kidney Disease (CKD symptom load and the European Quality of Life (EuroQol questionnaire for assessing the QoL of patients in the Renal Outpatient Clinic, Haemodialysis and Peritoneal Dialysis Unit. Results: It was found that the Renal Replacement Method (HD or PD, the presence of DM and CKD’s stage affect significantly the patients’ self-assessment regarding painful symptoms of DN. Furthermore, the above factors have major impact on some aspects of patients’ QoL, such as mobility and self-care. Conclusions: Pre-End Stage patients experience more severe painful symptoms of DN compared to patients on Renal Replacement Therapies.

    Introduction Magnetic resonance imaging (MRI) can be used to identify biomarkers in Parkinson’s disease (PD); R2* values reflect iron content related to high levels of oxidative stress, whereas volume and/or shape changes reflect neuronal death. We sought to assess iron overload in the nigrostriatal system and characterize its relationship with focal and overall atrophy of the striatum in the pivotal stages of PD. Methods Twenty controls and 70 PD patients at different disease stages (untreated de novo patients, treated early-stage patients and advanced-stage patients with L-dopa-related motor complications) were included in the study. We determined the R2* values in the substantia nigra, putamen and caudate nucleus, together with striatal volume and shape analysis. We also measured R2* in an acute MPTP mouse model and in a longitudinal follow-up two years later in the early-stage PD patients. Results The R2* values in the substantia nigra, putamen and caudate nucleus were significantly higher in de novo PD patients than in controls. Early-stage patients displayed significantly higher R2* values in the substantia nigra (with changes in striatal shape), relative to de novo patients. Measurements after a two-year follow-up in early-stage patients and characterization of the acute MPTP mouse model confirmed that R2* changed rapidly with disease progression. Advanced-stage patients displayed significant atrophy of striatum, relative to earlier disease stages. Conclusion Each pivotal stage in PD appears to be characterized by putative nigrostriatal MRI biomarkers: iron overload at the de novo stage, striatal shape changes at early-stage disease and generalized striatal atrophy at advanced disease.

    Purpose : The aim of this study is to analyze the survival rate, treatment failure and complication of radiation therapy alone in stage III uterine cervical cancer. Materials and Methods : From January 1980 through December 1985, 227 patients with stage II uterine cervical cancer treated with radiation therapy at Kosin Medical Center were retrospectively studied. Among 227 patients, 72 patients(31.7%) were stage IIIa, and 155 patients(68.3%) were stage IIIb according to FIGO classification. Age distribution was 32-71 years(median: 62 years). Sixty nine patients(95.8%) in stage IIIa and 150 patients(96.8%) in stage IIIb were squamous cell carcinoma. Pelvic lymph node metastasis at initial diagnosis was 8 patients (11.1%) in stage IIIa and 29 patients(18.7%) in stage IIIb. Among 72 patients with stage IIIa, 36 patients(50%) were treated with external radiation therapy alone by conventional technique (180-200 cGy/fr). And 36 patients(50%) were treated with external radiation therapy with intracavitary radiotherapy(ICR) with Cs137 sources, and among 155 patients with stage IIIb, 80 patients(51.6%) were treated with external radiation therapy alone and 75 patients(48.4%) were treated with external radiation therapy with ICR. Total radiation doses of stage IIIa and IIIb were 65-105 Gy(median : 78.5 Gy) and 65-125.5 Gy (median :83.5 Gy). Survival rate was calculated by life-table method. Results : Complete response rates were 58.3% (42 patients) in state IIIa and 56.1%(87 patients) in stage Iiib. Overall 5 year survival rates were 57% in stage IIIa and 40% in stage IIIb. Five year survival rates by radiation technique in stage IIIa and IIIb were 64%, 40% in group treated in combination of external radiation and ICR, and 50%, 40% in the group of external radiation therapy alone(P=NS). Five year survival rates by response of radiation therapy in stage IIIa and IIIb were 90%, 66% in responder group, and 10%, 7% in non-responder group (P<0.01). There were statistically no

Among 227 patients, 72 patients(31.7%) were stage IIIa, and 155 patients(68.3%) were stage IIIb according to FIGO classification. Age distribution was 32-71 years(median: 62 years). Sixty nine patients(95.8%) in stage IIIa and 150 patients(96.8%) in stage IIIb were squamous cell carcinoma. Pelvic lymph node metastasis at initial diagnosis was 8 patients (11.1%) in stage IIIa and 29 patients(18.7%) in stage IIIb. Among 72 patients with stage IIIa, 36 patients(50%) were treated with external radiation therapy alone by conventional technique (180-200 cGy/fr). And 36 patients(50%) were treated with external radiation therapy with intracavitary radiotherapy(ICR) with Cs137 sources, and among 155 patients with stage IIIb, 80 patients(51.6%) were treated with external radiation therapy alone and 75 patients(48.4%) were treated with external radiation therapy with ICR. Total radiation doses of stage IIIa and IIIb were 65-105 Gy(median : 78.5 Gy) and 65-125.5 Gy (median :83.5 Gy). Survival rate was calculated by life-table method. Results : Complete response rates were 58.3% (42 patients) in state IIIa and 56.1%(87 patients) in stage Iiib. Overall 5 year survival rates were 57% in stage IIIa and 40% in stage IIIb. Five year survival rates by radiation technique in stage IIIa and IIIb were 64%, 40% in group treated in combination of external radiation and ICR, and 50%, 40% in the group of external radiation therapy alone(P=NS). Five year survival rates by response of radiation therapy in stage IIIa and IIIb were 90%, 66% in responder group, and 10%, 7% in non-responder group (P<0.01). There were statistically no

    A series of 510 patients with carcinoma of the uterine cervix given the curative radiation therapy from March 1979 through December 1986 was evaluated to determine the value of intravenous pyelography(IVP), cystoscopy, sigmoidoscopy, and abdomino-pelvic CT as staging work-up prior to treatment. On IVP and cystoscopy, 10.7%(49/456) and 5/3%(24/452) showed abnormality, respectively, but only 0.7% (3/413) did on signoidoscopy. As a result of these work-ups prerequisite to FIGO staging, twenty six (5.1%) out of 510 patients were upstaged from the stage determined by the findings of physical examination alone. The proportions of upstaging in each stage were as follows none in stage IB(35), IIA (89) and IIIA(8), 7.9%(20/252) in stage IIB(14 patients to FIGO Stage IIIB, 6 patients to FIGO stage IVA), and 4.8% (6/126) in stage IIIB (all to FIGO stage IVA). Positive findings of staging work-ups were found only in patients with advanced stages of stage IIB or over determined by physical examination alone but not in those with earlier stages. CT was performed in 337 patients. CT detected pelvic lymph node (LN) enlargement in 25.2% (85/337) and paraaortic LN enlargement in 7.4% (25/337). Pelvic LN positivity was well correlated with increasing stage but paraaortic LN positivity was not. In the evaluation of parametrial involvement, CT findings were in accordance with those of physical examination only in 65.6%(442/674). When compared with endoscopic studies, CT had much lower positive predictive value than negative predictive value in the evaluation of adjacent organ invasion. The staging work-ups should be individualized by the disease extent of each patient, and then the efficiency of work-ups may be increased without compromising the appropriate FIGO staging and treatment

    2017-08-01

    Valvular heart disease (VHD), particularly aortic valve disease, is prevalent with increasing incidence. When surgery is not possible, or when risks outweigh benefits, percutaneous treatment options may offer effective alternatives. However, procedures may not always go as planned, and frail patients or those whose symptoms are caused by other comorbidities may not benefit from valve intervention at all. Significant effort should be made to assess frailty, comorbidities and patient goals prior to intervention. Palliative care (PC) should play a critical role in the care of patients with severe valve disease. PC is specialised medical care that aims to optimise health-related quality of life by managing symptoms and clarifying patient values and goals of care. It should be implemented at the time of diagnosis and continue throughout the disease course. Because of the paucity of studies dedicated to the provision of PC to patients with advanced VHD, further research is needed. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Twenty-one patients (26 hips) with typical signs of Legg-Perthes-Calve (LPC) disease on plain radiographs were explored by MRI. Patients were imaged with a 0.5 T MR unit. Gadolinium-enhanced spinecho MR images were obtained after nonenhanced T1-weighted (spin-echo) and T2[sup *]-weighted (gradient-echo) images. Four different areas were identified in the femoral epiphysis (necrosis, regenerative, cartilaginous and normal fatty bone tissue). The histological evolution of LPC is well described by Catterall and others. Comparing their descriptions with out MR findings, we suggest classification ofLPC into five phases: necrosis: regeneration, reconstruction, reossification and sequelae. (orig.)

    1983-01-01

    A total of 241 patients (482 sacroiliac indices) in different X-ray stage of the disease were studied and the data obtained were correlated with the sacroiliac indices in a control group of 104 normal subjects (208 sacroiliac indices). Sacroiliac indices were obtained by quantitative examination of the zones of interest of the sacroiliac joints and the sacrum, 3 hours after intravenous injection of 99 sup(m)Tc-pyrophosphate in indicator activities of 1.85 MBq/kg. The sacroiliac index levels increased with advancing X-ray stage of the disease within the I-III stage span; in the IV-th X-ray stage there was obvious decrease in these values. There appeared to exist statistically significant differences in the sacroiliac index values during all X-ray stages of the disease, as compared to the data obtained in the control group of healthy individuals (P<0.001). The significance level of the differences between neighbouring stages was low. Peak percentage of negative findings was observed in the zero stage (14.3) and in stage IV (11.7). The high percentage of positive findings in zero stage patients (15.7 per cent) is an evidence of the major sensitivity of quantitative scintigraphy in comparison with X-ray method of examination.

    Although most of the statistical methods for diagnostic studies focus on disease processes with binary disease status, many diseases can be naturally classified into three ordinal diagnostic categories, that is normal, early stage, and fully diseased. For such diseases, the volume under the ROC surface (VUS) is the most commonly used index of diagnostic accuracy. Because the early disease stage is most likely the optimal time window for therapeutic intervention, the sensitivity to the early diseased stage has been suggested as another diagnostic measure. For the purpose of comparing the diagnostic abilities on early disease detection between two markers, it is of interest to estimate the confidence interval of the difference between sensitivities to the early diseased stage. In this paper, we present both parametric and non-parametric methods for this purpose. An extensive simulation study is carried out for a variety of settings for the purpose of evaluating and comparing the performance of the proposed methods. A real example of Alzheimer's disease (AD) is analyzed using the proposed approaches. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    2002-01-01

    The main purpose of this study is to determine signs and indexes useful for differentiating grades of appendicitis (catarrhal, phlegmonous, gangrenous). We assessed CT findings of 98 cases of appendicitis retrospectively. Nonenhanced CT scans were obtained in 83 cases and enhanced scans in 15 cases. No patients were given oral or colon contrast media. Each examination was performed from the level of the diaphragm to the pubic symphysis with 10 mm or 7 mm slice thickness and intervals. All images were examined for CT signs of appendicitis and the diameter and appearance of the appendix. We statistically analyzed the results and white blood cell count. We detected an abnormal appendix in 88 cases. Two CT signs identified and their sensitivity, specificity, and accuracy, respectively, included fat stranding around the appendix (92.2%, 81.8%, 90.9%) and indistinct wall of the appendix (63.9%, 94.2%, 81.8%). The diameter of the appendix differed significantly among the three grades (p=0.0008). The appearance of the appendix could be divided into 5 types, which exhibited correlation with the grades, although white blood cell count did not (p=0.1988). Fat stranding and indistinct wall, and appendix diameter and CT appearances provided useful signs and indexes for staging of appendicitis. (author)

    The relationship between motor impairment and cognitive deterioration has long been described in Parkinson's disease (PD). The aim of the study was to compare cognitive performance of de novo PD patients in relation to the motor impairment severity according to Hoehn and Yahr (HY) stages. Forty de novo PD patients at HY stage I and 40 patients at HY stage II completed a standardized neuropsychological battery. A multivariate analysis of covariance was used to compare cognitive performance between HY groups. Odds ratios (ORs) were employed to explore the risk of cognitive impairment between HY stages. Finally, the prevalence of mild cognitive impairment (MCI) was estimated for patients in HY stage I and II. Patients at HY stage I obtained better scores on neuropsychological tests than patients at HY stage II (p = 0.001). Univariate analysis of covariance revealed significant differences between HY stages on Rey's auditory verbal learning test -immediate recall (p cognitive impairment were greater for HY stage II than stage I group. MCI occurred in 7.5% of patients in HY stage I, and in 42.5% of patients in HY stage II. In de novo PD patients, the severity of motor impairment at the diagnosis is associated to cognitive deficits and higher risk of MCI. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2018-02-01

    As a noninvasive and easily available biological fluid, the urine is becoming an important source for disease biomarker study. Change is essential for the usefulness of a biomarker. Without homeostasis mechanisms, urine can accommodate more changes, especially in the early stages of diseases. In this review, we summarize current status and discuss perspectives on the discovery of urine biomarkers in the early stages of diseases. We emphasize the advantages of urine biomarkers compared to plasma biomarkers for the diagnosis of diseases at early stages, propose a urine biomarker research roadmap, and highlight a novel membrane storage technique that enables large-scale urine sample collection and storage efficiently and economically. It is anticipated that urine biomarker studies will greatly promote early diagnosis, prevention, treatment, and prognosis of a variety of diseases, and provide strong support for translational and precision medicine.

  17. Evaluation of functional changes in the evolutionary stages of Parkinson's disease: a case series

    Directory of Open Access Journals (Sweden)

    Natália Feitoza do Nascimento

    Full Text Available Abstract Introduction : Parkinson's disease is one of the fastest growing neurological disorders in the world and is considered to be predominantly a motor disorder, classified as neurodegenerative, chronic and extrapyramidal, characterized by tremors, muscular rigidity, postural balance deficit and bradykinesia. Objective : To analyze the functional changes presented by Parkinson's disease patients in the different evolutionary stages of the disease. Methods : The sample included 30 patients of both genders, aged between 51 and 75 years, with clinical diagnoses of Parkinson's disease in different evolutionary stages, undergoing physiotherapy in the Pernambuco Parkinson Association. The patients were evaluated through the Hoehn and Yahr Staging Scale and the Unified Parkinson's Disease Rating Scale (UPDRS. Results : The results highlighted an increase in the presence and severity of the changes presented by the Parkinson's disease patients, according to the evolution of the stages of the disease, especially considering aspects relating to motor activity and activities of daily living, including changes related to speech, swallowing, the ability to get dressed, personal hygiene, turning in bed and arising from a chair, occurrence of falls, posture, gait, postural stability and the presence of bradykinesia/hypokinesia. Conclusion : It is believed that the classification of the evolutionary stage of patients through the Hoehn and Yahr Scale and the registration of functional change through the UPDRS are useful for the development of the physiotherapy treatment plan.

    In Venezuela there are 3234 new cases (132 per million population [pmp]) requiring renal replacement therapy each year, and only 40% of these are admitted to the different modalities of dialysis. In the year 2000, there were 195 patients pmp in chronic hemodialysis (4700 patients). Diabetes, glomerular diseases, and hypertension account for more than 60% of the patients in chronic dialysis. Gross mortality in hemodialysis is around 20%, and cardiovascular causes are the primary cause of death (39.5%). Hospital admission in the dialysis patients amounts to 4.6 days/patient/year. Rehabilitation is inadequate. Only 45% of the dialysis patients report normal home or work activities. Transplantation in Venezuela has a general graft survival rate of 83% at 1 year (90% for living related grafts) and 50% (64% for living related grafts) at 10 years. Future tendencies include emphasis in preventive strategies, including early detection and treatment of diabetes and hypertension, as well as efforts to increase the rate of renal transplantation.

    1994-01-01

    The records of all patients with stage I and II Hodgkin's disease treated with radiotherapy alone at the Royal Adelaide Hospital between 1970 and 1986 were reviewed. The aim was to ensure the results were equivalent to the best reported series, particularly as treating such patients with chemotherapy alone has been shown to produce equivalent overall survival figures with improved relapse-free survival. There were 104 patients of whom 67 and undergone staging laparotomy. Fifty-seven patients were stage I and 47 stage II. Nine patients had B symptoms. Overall survival at 10 years was 83% with disease-specific survival being 86% and relapse-free survival 68%. These results compare favourably with those in the world literature. Multivariate analysis only revealed stage as an independent predictor of improved relapse-free survival. 30 refs., 3 figs., 3 tabs

    In this study, the aim was to identify the incidence of sarcopenia and dynapenia according to disease stage among idiopathic Parkinson's disease (IPD) patients and collect data to illuminate precautions related to reducing the disease load. The study was completed with 166 patients divided by stage according to modified Hoehn and Yahr (HYR) criteria and 249 healthy volunteers aged from 18 to 39 and 68 to 75 years met the inclusion criteria. In our prospective and cross-sectional study, patients with IPD according to "UK Brain Bank" diagnostic criteria had the Unified Parkinson's Disease Rating Scale (UPDRS) and HYR scales applied. The patient and control groups had skeletal muscle mass index (SMMI), muscle power, and physical performance assessed. Diagnosis of sarcopenia used the European Working Group on Sarcopenia in Older People (EWGSOP) diagnostic criteria. In our study, in parallel with the increase in disease stage among IPD patients, the incidence of sarcopenia (led by severe sarcopenia) and dynapenia was high compared to that among the control group of the same age. In the early stages of chronic progressive diseases like IPD, identification of sarcopenia and dynapenia is important considering the limitations of disease-preventive effects in treatments applied after diagnosis.

    Combining immunotherapeutic agents with different mechanisms of action may enhance efficacy. We describe the safety and efficacy of talimogene laherparepvec (T-VEC; an oncolytic virus) in combination with ipilimumab (a cytotoxic T-lymphocyte-associated antigen 4 checkpoint inhibitor) in patients with advanced melanoma. In this open-label, multicenter, phase Ib trial of T-VEC in combination with ipilimumab, T-VEC was administered intratumorally in week 1 (10(6) plaque-forming units/mL), then in week 4 and every 2 weeks thereafter (10(8) plaque-forming units/mL). Ipilimumab (3 mg/kg) was administered intravenously every 3 weeks for four infusions, beginning in week 6. The primary end point was incidence of dose-limiting toxicities. Secondary end points were objective response rate by immune-related response criteria and safety. Median duration of treatment with T-VEC was 13.3 weeks (range, 2.0 to 95.4 weeks). Median follow-up time for survival analysis was 20.0 months (1.0 to 25.4 months). Nineteen patients were included in the safety analysis. No dose-limiting toxicities occurred, and no new safety signals were detected. Grade 3/4 treatment-related adverse events (AEs) were seen in 26.3% of patients; 15.8% had AEs attributed to T-VEC, and 21.1% had AEs attributed to ipilimumab. The objective response rate was 50%, and 44% of patients had a durable response lasting ≥ 6 months. Eighteen-month progression-free survival was 50%; 18-month overall survival was 67%. T-VEC with ipilimumab had a tolerable safety profile, and the combination appeared to have greater efficacy than either T-VEC or ipilimumab monotherapy. © 2016 by American Society of Clinical Oncology.

    To investigate arterial spin-labelling (ASL) cerebral blood flow (CBF) changes in predementia stages of Alzheimer's disease (AD). Data were obtained from 177 patients with subjective complaints, mild cognitive impairment and AD from the Amsterdam Dementia Cohort. AD stages were based on diagnosis and cerebrospinal fluid biomarkers amyloid-β (Aβ) and total-tau (tau). General-linear-models were used to assess relationships between AD stages and total and regional CBF, correcting for age and sex. Decreasing CBF was related to more advanced AD stages in all supratentorial regions (p for trend < 0.05). Post-hoc testing revealed that CBF was lower in AD compared to controls and stage-1 predementia patients (i.e. abnormal Aβ and normal tau) in temporal and parietal regions, and compared to stage-2 predementia patients (i.e. abnormal Aβ and tau) in temporal regions. CBF values of stage-2 predementia patients were numerically in between those of stage-1 predementia patients and AD. The continuing decrease of CBF along the continuum of AD indicates the potential of ASL-CBF as a measure for disease progression. (orig.)

    Stage IIIA non-small cell lung cancer (NSCLC) is heterogeneous in tumor burden, and its treatment is variable. Whole-body metabolic tumor volume (MTV{sub WB}) has been shown to be an independent prognostic index for overall survival (OS). However, the potential of MTV{sub WB} to risk-stratify stage IIIA NSCLC has previously been unknown. If we can identify subgroups within the stage exhibiting significant OS differences using MTV{sub WB}, MTV{sub WB} may lead to adjustments in patients' risk profile evaluations and may, therefore, influence clinical decision making regarding treatment. We estimated the risk-stratifying capacity of MTV{sub WB} in stage IIIA by comparing OS of stratified stage IIIA with stage IIB and IIIB NSCLC. We performed a retrospective review of 330 patients with clinical stage IIB, IIIA, and IIIB NSCLC diagnosed between 2004 and 2014. The patients' clinical TNM stage, initial MTV{sub WB}, and long-term survival data were collected. Patients with TNM stage IIIA disease were stratified by MTV{sub WB}. The optimal MTV{sub WB} cutoff value for stage IIIA patients was calculated using sequential log-rank tests. Univariate and multivariate cox regression analyses and Kaplan-Meier OS analysis with log-rank tests were performed. The optimal MTV{sub WB} cut-point was 29.2 mL for the risk-stratification of stage IIIA. We identified statistically significant differences in OS between stage IIB and IIIA patients (p < 0.01), between IIIA and IIIB patients (p < 0.01), and between the stage IIIA patients with low MTV{sub WB} (below 29.2 mL) and the stage IIIA patients with high MTV{sub WB} (above 29.2 mL) (p < 0.01). There was no OS difference between the low MTV{sub WB} stage IIIA and the cohort of stage IIB patients (p = 0.485), or between the high MTV{sub WB} stage IIIA patients and the cohort of stage IIIB patients (p = 0.459). Similar risk-stratification capacity of MTV{sub WB} was observed in a large range of cutoff values from 15 to 55 mL in

    The preferred histopathological classification of Hodgkin's disease (HD) is suggested by Lukes and Butler as modified at the Rye Symposium; the histologic subtypes are highly reproducible and correlate well with the anatomic sites of involvement, clinical stage, and survival. The accuracy of the bipedal lymphangiogram, /sup 67/gallium scan, and ultrasonography in predicting abdominal involvement by HD is 90 percent, 50 percent, and 88 percent, respectively. Staging laparotomy remains the most accurate method of detecting intra-abdominal disease and has added immensely to new concepts in the management of HD. These concepts suggest that patients with nodal disease limited to the celiac axis or upper para-aortic areas (substage III/sub 1/) or pathologic stage (PS) III/sub S+N-/A, when treated with extended field radiotherapy alone have survival rates comparable to PS IIA patients. In contrast, patients in PS IIIA with lower abdominal nodal disease (substage III/sub 2/), regardless of splenic involvement, have a prognosis comparable to PS IV disease. Thus, there may only be two stages of HD, those curable with extended mantle or smaller radiotherapy fields alone, and those requiring chemotherapy with or without supplemental radiotherapy.

    To investigate the skin innervation and its clinical significance in late-stage chronic kidney disease (CKD). Case series. National Taiwan University Hospital, Taipei, Taiwan. Forty consecutive nondiabetic patients with late-stage CKD (14 female and 26 male; mean [SD] age, 60.7 [12.3] years), including 2 cases with stage 3 CKD, 6 with stage 4 CKD, and 32 with stage 5 CKD, ie, end-stage kidney disease. Clinical evaluation of neurological deficits, nerve conduction study, autonomic function tests, and a 3-mm-diameter skin biopsy specimen taken from the distal leg. Quantitation of epidermal innervation, parameters of nerve conduction study, R-R interval variability, and sympathetic skin response. Clinically, 21 patients (52.5%) were symptomatic with paresthesia over the limbs or autonomic symptoms. The intraepidermal nerve fiber (IENF) density was markedly reduced in patients with CKD compared with age- and sex-matched controls (mean [SD], 2.8 [2.0] vs 8.6 [2.8] fibers/mm; P Skin denervation was observed in 27 patients (67.5%). Fifteen patients (37.5%) had abnormalities on nerve conduction studies, and 29 patients (72.5%) had abnormal results on autonomic function tests. By analysis with multiple regression models, the IENF density was negatively correlated with the duration of renal disease (P = .02). Additionally, the R-R interval variability at rest was linearly correlated with the IENF density (P = .02) and the absence of sympathetic skin responses at the soles was associated with reduced IENF density (P = .03). Small-fiber sensory and autonomic neuropathies constitute the major form of neuropathy in late-stage CKD. Furthermore, skin denervation was associated with the duration of renal disease.

    To examine the outcomes and risk factors in pediatric differentiated thyroid carcinoma (DTC) patients who were defined as TNM stage I because some patients develop disease recurrence but treatment strategy for such stage I pediatric patients is still controversial. We reviewed 57 consecutive TNM stage I patients (15 years or less) with DTC (46 papillary and 11 follicular) who underwent initial treatment at Ito Hospital between 1962 and 2004 (7 males and 50 females; mean age: 13.1 years; mean follow-up: 17.4 years). Clinicopathological results were evaluated in all patients. Multivariate analysis was performed to reveal the risk factors for disease-free survival (DFS) in these 57 patients. Extrathyroid extension and clinical lymphadenopathy at diagnosis were found in 7 and 12 patients, respectively. Subtotal/total thyroidectomy was performed in 23 patients, modified neck dissection in 38, and radioactive iodine therapy in 10. Pathological node metastasis was confirmed in 37 patients (64.9%). Fifteen patients (26.3%) exhibited local recurrence and 3 of them also developed metachronous lung metastasis. Ten of these 15 achieved disease-free after further treatments and no patients died of disease. In multivariate analysis, male gender (p = 0.017), advanced tumor (T3, 4a) stage (p = 0.029), and clinical lymphadenopathy (p = 0.006) were risk factors for DFS in stage I pediatric patients. Male gender, tumor stage, and lymphadenopathy are risk factors for DFS in stage I pediatric DTC patients. Aggressive treatment (total thyroidectomy, node dissection, and RI therapy) is considered appropriate for patients with risk factors, whereas conservative or stepwise approach may be acceptable for other patients

    Full Text Available Objective To analyze the sensitivity of auxiliary examinations in different periods of sporadic Creutzfeldt-Jakob disease (sCJD. Methods The clinical data of 53 sCJD patients were retrospectively analyzed including the different stages of skull diffusion-weighted magnetic resonance imaging (DWI, 24-hour ambulatory electroencephalogram (EEG, 18F-FDG PET/CT (PET-CT and cerebrospinal fluid 14-3-3 protein. When calculating the sensitivity of an auxiliary examination, the diagnostic criteria were defined by combining the specific clinical manifestations with two or more positive results of other auxiliary examinations. Results There were 24, 53 and 22 sCJD patients, respectively, met the criterion of early (E, middle (M and later (L stage of disease (some patients fit 2 or 3 stages. The sensitivity of DWI (E: 58.3%, M: 85.4%, L: 94.7%, EEG (E: 45.8%, M: 62.7%, L: 77.8%, 14-3-3 protein in cerebrospinal fluid (E: 11.1%, M: 52.9% and PET-CT (E: 80%, M: 100% increased gradually with disease progression. The sensitivity of PET-CT was higher than the other auxiliary examinations for E and M stages; no PET-CT was conducted in L stage. High signal regions mainly distributed in the cortex in E and M stages, but in L stage, no significant difference was found on the distribution of high signal regions between cortex and basal ganglia. Conclusions The sensitivities of the auxiliary examinations were different for sCJD patients in different stages. Reexaminations in different periods may improve the sensitivity for sCJD diagnosis. The sensitivity of PET-CT was high, and the combination of PET-CT and other auxiliary examinations may play a key role in the diagnosis of sCJD. DOI: 10.11855/j.issn.0577-7402.2017.05.15

    Purpose: Analysis of treatment outcome for Stage I-IIA supradiaphragmatic Hodgkin's disease treated solely by irradiation in Australia and New Zealand. Methods and Materials: Patients with supradiaphragmatic Hodgkin's disease only who were treated by irradiation alone with curative intent between 1969 to 1988 were retrospectively reviewed. Ten radiation oncology departments in Australia and New Zealand contributed patient data to the study. Patient, tumor, and treatment variables were recorded. Disease-free interval, survival, and complications were analyzed. Results: Eight hundred and twenty patients were reviewed. The median age was 29 years. There were 437 men and 383 women. The distribution of 310 clinically staged patients was 170 stage IA, 5 IB, and 135 IIA. Five hundred and ten patients received laparotomies, and pathologic staging was as follows: IA 214, IB 13, IIA 283. The 10-year acturial disease-free rate was 69% and overall survival rate was 79%. Increasing age, male sex, higher number of involved sites, the use of involved field irradiation, no staging laparotomy, and earlier year of treatment were significantly associated with an increased risk of relapse and lower survival. Actuarial 10-year survival following recurrence was 48%. Acute complications requiring interruption to treatment occurred in 46 patients (6%), but < 1% had their treatment permanently suspended. Actuarial complication rates at 10 years were: cardiac 2%, pulmonary 3% and thyroid 5%. There were 44 second malignancies including 10 non-Hodgkin's lymphomas, 3 leukemias, 7 lung, and 6 breast cancers. Mean delay to the development of a second cancer was 6 years. The 10-year actuarial rate of second malignancy was 5%. Conclusions: The Australasian experience of early stage Hodgkin's disease is consistent with the results in the published literature and confirms that irradiation produces a high cure rate with minimal toxicity.

Actuarial 10-year survival following recurrence was 48%. Acute complications requiring interruption to treatment occurred in 46 patients (6%), but < 1% had their treatment permanently suspended. Actuarial complication rates at 10 years were: cardiac 2%, pulmonary 3% and thyroid 5%. There were 44 second malignancies including 10 non-Hodgkin's lymphomas, 3 leukemias, 7 lung, and 6 breast cancers. Mean delay to the development of a second cancer was 6 years. The 10-year actuarial rate of second malignancy was 5%. Conclusions: The Australasian experience of early stage Hodgkin's disease is consistent with the results in the published literature and confirms that irradiation produces a high cure rate with minimal toxicity

    This study aims to develop a valid and reliable chronic kidney disease self-management instrument (CKD-SM) for assessing early stage chronic kidney disease patients' self-management behaviours. Enhancing early stage chronic kidney disease patients' self-management plays a key role in delaying the progression of chronic kidney disease. Healthcare provider understanding of early stage chronic kidney disease patients' self-management behaviours can help develop effective interventions. A valid and reliable instrument for measuring chronic kidney disease patients' self-management behaviours is needed. A cross-sectional descriptive study collected data for principal components analysis with oblique rotation. Mandarin- or Taiwanese-speaking adults with chronic kidney disease (n=252) from two medical centres and one regional hospital in Southern Taiwan completed the CKD-SM. Construct validity was evaluated by exploratory factor analysis. Internal consistency and test-retest reliability were estimated by Cronbach's alpha and Pearson correlation coefficients. Four factors were extracted and labelled self-integration, problem-solving, seeking social support and adherence to recommended regimen. The four factors accounted for 60.51% of the total variance. Each factor showed acceptable internal reliability with Cronbach's alpha from 0.77-0.92. The test-retest correlations for the CKD-SM was 0.72. The psychometric quality of the CKD-SM instrument was satisfactory. Research to conduct a confirmatory factor analysis to further validate this new instrument's construct validity is recommended. The CKD-SM instrument is useful for clinicians who wish to identify the problems with self-management among chronic kidney disease patients early. Self-management assessment will be helpful to develop intervention tailored to the needs of the chronic kidney disease population. © 2013 Blackwell Publishing Ltd.

  2. Temporal order of RNase IIIb and loss-of-function mutations during development determines phenotype in pleuropulmonary blastoma / DICER1 syndrome: a unique variant of the two-hit tumor suppression model [version 2; referees: 2 approved

    Full Text Available Pleuropulmonary blastoma (PPB is the most frequent pediatric lung tumor and often the first indication of a pleiotropic cancer predisposition, DICER1 syndrome, comprising a range of other individually rare, benign and malignant tumors of childhood and early adulthood. The genetics of DICER1-associated tumorigenesis are unusual in that tumors typically bear neomorphic missense mutations at one of five specific “hotspot” codons within the RNase IIIb domain of DICER 1, combined with complete loss of function (LOF in the other allele. We analyzed a cohort of 124 PPB children for predisposing DICER1 mutations and sought correlations with clinical phenotypes. Over 70% have inherited or de novo germline LOF mutations, most of which truncate the DICER1 open reading frame. We identified a minority of patients who have no germline mutation, but are instead mosaic for predisposing DICER1 mutations. Mosaicism for RNase IIIb domain hotspot mutations defines a special category of DICER1 syndrome patients, clinically distinguished from those with germline or mosaic LOF mutations by earlier onsets and numerous discrete foci of neoplastic disease involving multiple syndromic organ sites. A final category of PBB patients lack predisposing germline or mosaic mutations and have sporadic (rather than syndromic disease limited to a single PPB tumor bearing tumor-specific RNase IIIb and LOF mutations. We propose that acquisition of a neomorphic RNase IIIb domain mutation is the rate limiting event in DICER1-associated tumorigenesis, and that distinct clinical phenotypes associated with mutational categories reflect the temporal order in which LOF and RNase IIIb domain mutations are acquired during development.

  5. Central Pain Processing in Early-Stage Parkinson's Disease: A Laser Pain fMRI Study.

    Full Text Available Pain is a common non-motor symptom in Parkinson's disease. As dopaminergic dysfunction is suggested to affect intrinsic nociceptive processing, this study was designed to characterize laser-induced pain processing in early-stage Parkinson's disease patients in the dopaminergic OFF state, using a multimodal experimental approach at behavioral, autonomic, imaging levels.13 right-handed early-stage Parkinson's disease patients without cognitive or sensory impairment were investigated OFF medication, along with 13 age-matched healthy control subjects. Measurements included warmth perception thresholds, heat pain thresholds, and central pain processing with event-related functional magnetic resonance imaging (erfMRI during laser-induced pain stimulation at lower (E = 440 mJ and higher (E = 640 mJ target energies. Additionally, electrodermal activity was characterized during delivery of 60 randomized pain stimuli ranging from 440 mJ to 640 mJ, along with evaluation of subjective pain ratings on a visual analogue scale.No significant differences in warmth perception thresholds, heat pain thresholds, electrodermal activity and subjective pain ratings were found between Parkinson's disease patients and controls, and erfMRI revealed a generally comparable activation pattern induced by laser-pain stimuli in brain areas belonging to the central pain matrix. However, relatively reduced deactivation was found in Parkinson's disease patients in posterior regions of the default mode network, notably the precuneus and the posterior cingulate cortex.Our data during pain processing extend previous findings suggesting default mode network dysfunction in Parkinson's disease. On the other hand, they argue against a genuine pain-specific processing abnormality in early-stage Parkinson's disease. Future studies are now required using similar multimodal experimental designs to examine pain processing in more advanced stages of Parkinson's disease.

  6. Diagnosis of Alzheimer’s Disease with [18F]PET in Mild and Asymptomatic Stages

    Full Text Available With longer life expectancy, dementia based on the age-related Alzheimers’ disease (AD has turned into one of the most prevalent disorders of older age, representing a serious medical and socio-economic issue. There has been growing interest in early diagnosis of this disease, particularly regarding the initiation of new treatment strategies ahead of the onset of irreversible neuronal damage. It is accepted that the pathologic changes underlying AD appear in the brain years to decades before the symptomatic stages. Consequently, clinical measures of cognitive impairment, as used for definition of dementia, will not allow early diagnosis of AD-pathology in the mild or asymptomatic stages. Thus, a need for complementary sensitive biomarkers is apparent. Brain imaging markers are among the most promising candidates for this diagnostic challenge. Particularly, [18F]FDG PET as a marker of regional neuronal function has been demonstrated to represent a most sensitive and specific method for early identification of AD-pathology and thus for prediction of dementia of the Alzheimer type (DAT, even in the mild and asymptomatic stages. Currently, systematic data of comparable quality are hardly available for any other imaging procedure. The purpose of this article is to describe the typical findings of [18F]FDG PET in different stages of AD and to demonstrate its value for early and reliable diagnosis of Alzheimer's disease, particularly ahead of the stage of dementia of the Alzheimer’s type.

  7. Lack of miRNA misregulation at early pathological stages in Drosophila neurodegenerative disease models

    Full Text Available Late onset neurodegenerative diseases represent a major public health concern as the population in many countries ages. Both frequent diseases such as Alzheimer disease (AD, 14% incidence for 80-84 year old Europeans or Parkinson disease (PD, 1.4% prevalence for > 55 years old share, with other low-incidence neurodegenerative pathologies such as spinocerebellar ataxias (SCAs, 0.01% prevalence and frontotemporal lobar degeneration (FTLD, 0.02% prevalence, a lack of efficient treatment in spite of important research efforts. Besides significant progress, studies with animal models have revealed unexpected complexities in the degenerative process, emphasizing a need to better understand the underlying pathological mechanisms. Recently, microRNAs, a class of small regulatory non-coding RNAs, have been implicated in some neurodegenerative diseases. The current data supporting a role of miRNAs in PD, tauopathies, dominant ataxias and FTLD will first be discussed to emphasize the different levels of the pathological processes which may be affected by miRNAs. To investigate a potential involvement of miRNA dysregulation in the early stages of these neurodegenerative diseases we have used Drosophila models for 7 diseases (PD, 3 FTLD, 3 dominant ataxias that recapitulate many features of the human diseases. We performed deep sequencing of head small RNAs after 3 days of pathological protein expression in the fly head neurons. We found no evidence for a statistically significant difference in miRNA expression in this early stage of the pathological process. In addition, we could not identify small non coding CAG repeat RNAs (sCAG in polyQ disease models. Thus our data suggest that transcriptional deregulation of miRNAs or sCAG is unlikely to play a significant role in the initial stages of neurodegenerative diseases.

    BACKGROUND AND PURPOSE: Previous volumetric magnetic resonance imaging (MRI) studies of Parkinson's disease (PD) utilized primarily voxel-based morphometry (VBM), and investigated mostly patients with moderate- to late-stage disease. We now use deformation-based morphometry (DBM), a method...... purported to be more sensitive than VBM, to test for atrophy in patients with early-stage PD. METHODS: T1-weighted MRI images from 24 early-stage PD patients and 26 age-matched normal control subjects were compared using DBM. Two separate studies were conducted, where two minimally-biased nonlinear...... intensity-average were created; one for all subjects and another for just the PD patients. The DBM technique creates an average population-based MRI-average in an iterative hierarchical fashion. The nonlinear transformations estimated to match each subject to the MRI-average were then analysed. RESULTS...

    Miguel Carreira, L; Daniela, Dias; Pedro, Azevedo

    2015-06-01

    Periodontal diseases (PD) are infectious, inflammatory, progressive diseases of the oral cavity affecting people and dogs. PD takes 2 forms: gingivitis and periodontitis. Diagnosing or staging PD can be achieved only with dental x-rays and periodontal probing, both of which require the use of general anesthesia in dogs. This study aimed to determine whether serum ionized calcium ([iCa(2+)]) levels can be useful in preliminary PD staging in dogs. A sample of 40 dogs (n = 40) was divided into 4 groups (n = 10 each) based on the following PD stages: G1 (gingivitis), G2 (initial periodontitis), G3 (moderate periodontitis), and G4 (severe periodontitis). The groups were then subjected to [iCa(2+)] quantification. Statistically significant differences were observed between PD stages and [iCa(2+)] for all stages except G3 and G4. Therefore, this parameter can be used as an additional tool to establish and monitor preliminary PD status. Copyright © 2015 Elsevier Inc. All rights reserved.

    2017-05-15

    This study aimed to analyse the feasibility and acute toxicity of radical hypo-fractionated radiotherapy (RT) for elderly patients with non-small-cell lung cancer (NSCLC). We conducted a retrospective evaluation of treatment with volumetric modulated arc therapy (VMAT) of elderly patients affected by stage III inoperable NSCLC. The dose prescription was 56 Gy in 20 fractions, 55 Gy in 22 fractions, or 50 Gy in 20 fractions. Target volume included only the primary lesion and the infiltrated lymph nodes. The primary end point was acute and late toxicity, while secondary end points were progression-free survival (PFS), and overall survival (OS). In all, 41 patients were included in this analysis. The mean age of the patients was 78.6 years, and 22 patients had staged IIIA while 19 patients had stage IIIB disease. All but one patient had pathological nodal involvement; 15 patients received chemotherapy before RT. Acute grade 1-2 toxicity was recorded in 25 (61%) patients. Late toxicity was recorded in 13 (32%) patients. No cases of G3 or G4 toxicity were recorded. Complete response was obtained in two (5%) patients, 26 (63%) showed a partial response, and two (5%) experience disease progression. At a mean follow-up of 9.9 months (range, 1.1-25.4), 17 patients had died from disease progression, one died from other causes, and 23 were alive. Median OS was 13.7 ± 1.5 months (95% CI: 10.7-16.7), OS at 12 and 18 months was 51.3 ± 9.5% and 35.1 ± 10.1%, respectively. Median PFS was 13.7 ± 2.3 months (95% CI: 9.1-18.2), and PFS at 12 and 18 months was 50.1 ± 9.9% and 38.9 ± 10.4%, respectively. Radical hypo-fractionated VMAT is a promising treatment for locally advanced NSCLC in the elderly. The use of hypo-fractionated radiotherapy for lung cancer in older patients can be considered a valuable approach, particularly for patients with poor performance status or refusing other treatment approaches.

    2017-05-01

    In Parkinson's disease (PD), several efforts have been spent in order to find biochemical parameters able to identify the progression of the pathological processes at the basis of the disease. It is already known that advanced PD patients manifesting dyskinesia are featured by the high homovanillic acid (HVA)/dopamine (DA) ratio, suggesting the increased turnover of DA in these patients. Less clear is whether similar changes affect mild and moderate stages of the disease (between 1 and 2.5 of Hoehn & Yahr -H&Y- stage). Hence, here we tested whether cerebrospinal fluid (CSF) concentrations of DA and its major metabolites, either 3,4-dihydroxyphenylacetic acid (DOPAC) or HVA, correlate with motor performance in mild and moderate PD patients. CSF samples were collected after 2 days of anti-PD drugs washout, via lumbar puncture (LP) performed 130 min following administration of oral levodopa (LD) dose (200 mg). LP timing was determined in light of our previous tests clarifying that 2 h after oral LD administration CSF DA concentration reaches a plateau, which was un-respective of PD stage or duration. DA, DOPAC and HVA were assayed by high performance liquid chromatography in a group of 19 patients, distributed in two groups on the basis of the H&Y stage with a cut-off of 1.5. In these PD patients, HVA was correlated with DOPAC (R = 0,56, p motor impairment. More importantly, HVA correlated with motor impairment measured by the Unified Parkinson's Disease Score -III (UPDRS) (R = 0.61; p motor impairment. Therefore, we suggest the potential use of measuring the CSF HVA level as a possible biomarker of PD stage changes in order to monitor the effectiveness of PD-modifying pharmacological therapies.

    We estimate a dynamic multi-stage duration model to investigate how early detection of diabetes can delay the onset of lower extremity complications and death. We allow for partial observability of the disease stage, unmeasured heterogeneity, and endogenous timing of diabetes screening. Timely diagnosis appears important. We evaluate the effectiveness of two potential policies to reduce the monetary costs of frequent screening in terms of lost longevity. Compared to the status quo, the more restrictive policy yields an implicit value for an additional year of life of about $50,000, while the less restrictive policy implies a value of about $120,000.

    Alzheimer's disease (AD) is a progressive neurodegenerative disease affecting millions of patients worldwide. Previous studies have demonstrated alterations in the lipid composition of lipid extracts from plasma and brain samples of AD patients. However, there is no consensus regarding the qualitative and quantitative changes of lipids in brains from AD patients. In addition, the recent developments in imaging mass spectrometry methods are leading to a new stage in the in situ analysis of lipid species in brain tissue slices from human postmortem samples. The present study uses the matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI-IMS), permitting the direct anatomical analysis of lipids in postmortem brain sections from AD patients, which are compared with the intensity of the lipid signal in samples from matched subjects with no neurological diseases. The frontal cortex samples from AD patients were classified in three groups based on Braak's histochemical criteria, ranging from non-cognitively impaired patients to those severely affected. The main results indicate a depletion of different sulfatide lipid species from the earliest stages of the disease in both white and gray matter areas of the frontal cortex. Therefore, the decrease in sulfatides in cortical areas could be considered as a marker of the disease, but may also indicate neurochemical modifications related to the pathogenesis of the disease.

    Contrary to well-recognized bleeding diathesis in chronic liver disease, thrombotic events can occur in these patients due to reduction or loss of synthesis of anticoagulant proteins. Forty-seven consecutive patients with end-stage liver disease (ESLD) were investigated for activity of protein C, protein S, antithrombin, and factor V Leiden mutation. Forty-two (89.4%) patients had low levels of at least 1 while 33 (70.2%) patients were deficient for all anticoagulant proteins studied. Forty-six (97.9%) patients were negative for factor V Leiden mutation. The deficiencies were more marked in hepatitis C virus-positive patients and patients with model for end-stage liver disease (MELD) score >15. Six (12.8%) patients had portal vein thrombosis (PVT), and all had diminished protein S activity. In conclusions, deficiency of anticoagulant proteins occur in early phase of chronic liver disease. The severity of deficiency is proportional to the severity of liver disease. Despite the high prevalence of hypercoagulability, the incidence of PVT is low. Further studies with larger cohort of patients are needed to support these conclusions and to study other associated factors.

    Treatment recommendations for patients with upper abdominal Stage IIIA Hodgkin's (III1A) disease have varied widely. The current study reports on a combined institutional retrospective review of 85 patients with surgically staged III1A Hodgkin's disease. Twenty-two patients received combined modality therapy (CMT), 36 patients were treated initially with total nodal irradiation (TNI), and 27 with mantle and para-aortic radiotherapy (MPA). Patients treated with CMT had an actuarial 8-year freedom from relapse (FFR) of 96% as compared to a FFR of 51% in TNI treated patients (p = 0.002), and a FFR of 54% in MPA treated patients (p = 0.004). Of the 11 relapses in MPA treated patients, 7 had a component of their failure in the untreated pelvic or inguinal nodes. The patients treated with CMT had an 8-year actuarial survival of 100% as compared to 79% in TNI treated patients (p = 0.055) and 78% in patients treated with MPA (p = 0.025). Histology and the number of splenic nodules were the most important prognostic variables. Patients with MC/LD histology and greater than or equal to 5 splenic nodules have a high risk of relapse (10/13) when treated with radiation alone (TNI or MPA). We recommend CMT for this group of patients. Patients with NS/LP histology and 1-4 splenic nodules represent a favorable subset of Stage III1A patients. Only 4/21 patients have relapsed and all 21 patients are currently alive without disease regardless of treatment. We currently feel that patients with Stage III1A Hodgkin's disease with NS/LP histology and splenic disease limited to 1-4 nodules are good candidates for MPA as an alternative to TNI or CMT.

    Purpose: To report long term follow-up results and analyze prognostic factors for overall and disease-free survival in patients with subdiaphragmatic stage I and II Hodgkin's disease. Methods and Materials: From September 1962 to April 1995, 109 patients presented to the M. D. Anderson Cancer Center with subdiaphragmatic Hodgkin's disease. The medical records of these patients were retrospectively reviewed. Twenty-two patients who received no treatment at M. D. Anderson Cancer Center or who had radiation therapy at other institutions were excluded. The remaining 87 patients formed the basis of this study. The median age of our group was 33 years with a male:female ratio of 3.3:1. The histological subtypes were nodular sclerosis in 21 (24.1%) patients, mixed cellularity in 31 (35.6%), lymphocyte predominence in 33 (37.9%), lymphocyte depletion in 1 (1.1%) and unclassified histology in 1 (1.1%). Thirty three (37%) patients underwent laparotomy, 74 (85.1%) had lymphangiography, and 35 (40.2%) had computerized tomography of the abdomen. Twenty two (25%) patients had more than three sites of nodal involvement at presentation, 56 (64.4%) had pelvic or abdominal disease, and 14 (18.4%) had bulky disease which was defined as disease with largest dimension ≥ 7 cm. Stage distribution was IA in 33.3%, IIA in 39.1%, and IIB in 27.6%. Sixty (69%) patients were treated with radiotherapy alone, 23 (26.4%) with chemotherapy and radiation, and 4 (4.6%) with chemotherapy alone. Results: The 10 and 20 year actuarial overall survival rates for all the patients were 74.6% and 55.3%, and the corresponding disease free survival rates were 72.4% and 67.5%, respectively. On univariate analysis, age, B symptoms, nodular sclerosis or mixed cellularity histology, and decreased albumin and hemoglobin level were statistically significant adverse pretreatment factors for overall survival. B symptoms, decreased albumin level, more than 3 sites of disease at presentation, and stage were

    The aim of this study was to evaluate our results of treatment for acute type IIIb aortic dissection associated with malperfusion of abdominal organs, and to consider the therapeutic strategies. Between December 1997 and August 2005, 123 patients with acute type IIIb aortic dissection were treated at our hospital. Of those, 11 patients (8.9%) required emergency treatment for malperfusion of abdominal organ. In our hospital, the indication of emergency treatment for acute type IIIb aortic dissection was any symptom of acute abdomen plus insufficiency of visceral arterial circulation on computed tomography or angiography. All of the 11 patients (100%) had cul-de-sac of a false lumen, 8 (72.7%) had at least one symptom of acute abdomen, and 3 (27.3%) had metabolic acidosis before surgical treatment. In 7 patients of the ''true lumen stenosis type,'' 5 patients who were treated with open stent grafting are alive. The other two patients, who were treated with transluminally placed endovascular stent grafting (TPEG) or with superior mesenteric artery (SMA) bypass, died. Of the 2 ''visceral arterial dissection type'' patient, one was treated with transluminal stenting of the celiac artery and the other was treated with resection of the intestine and ileocolic artery bypass, and both are alive. Two ''mixed type'' patients who were treated with open stent grafting died. The mortality rate of this series was 36.4%. In conclusion, to improve the prognosis of acute type IIIb aortic dissection associated with malperfusion of abdominal organ, it is important that we obtain early diagnosis of organ ischemia caused by cul-de-sac of a false lumen and choose the correct treatment based on understanding of the mechanism of organ ischemia.

    The development of durable ventricular assist devices (VADs) has improved mortality rates and quality of life in patients with end stage heart failure. While the use of VADs has increased dramatically in recent years, there is limited experience with VAD implantation in patients with complex congenital heart disease (CHD), despite the fact that the number of patients with end stage CHD has grown due to improvements in surgical and medical care. VAD use has been limited in patients with CHD and end stage heart failure due to anatomic (systemic right ventricle, single ventricle, surgically altered anatomy, valve dysfunction, etc.) and physiologic constraints (diastolic dysfunction). The total artificial heart (TAH), which has right and left sided pumps that can be arranged in a variety of orientations, can accommodate the anatomic variation present in CHD patients. This review provides an overview of the potential use of the TAH in patients with CHD.

    A variety of studies demonstrated that some forms of memory for music are spared in dementia, but only few studies have investigated patients with early stages of dementia. In this pilot-study we tested working memory for music in patients with mild cognitive impairment (MCI) and early stage Alzheimer's disease (AD) with a newly created test. The test probed working memory using 7 gradually elongated tone-lines and 6 chords which were each followed by 3 similar items and 1 identical item. The participants of the study, namely 10 patients with MCI, 10 patients with early stage AD and 23 healthy subjects were instructed to select the identical tone-line or chord. Subjects with MCI and early AD showed significantly reduced performance than controls in most of the presented tasks. In recognizing chords MCI- participants surprisingly showed an unimpaired performance. The gradual increase of the impairment during the preclinical phase of AD seems to spare this special ability in MCI.

  15. Role of low protein diet in management of different stages of chronic kidney disease - practical aspects.

    Chronic kidney disease (CKD) is a worldwide public health problem and more so in India. With limited availability and high cost of therapy, barely 10 % of patients with incident end stage renal disease (ESRD) cases get treatment in India. Therefore, all possible efforts should be made to retard progression of CKD. This article reviews the role of low protein diet (LPD) in management of CKD subjects and suggests how to apply it in clinical practice. The role of LPD in retarding progression of CKD is well established in animal experimental studies. However, its role in human subjects with CKD is perceived to be controversial based on the modification of diet in renal disease (MDRD) study. We believe that beneficial effect of LPD could not be appreciated due to shorter duration of follow-up in the MDRD study. Had the study been continued longer, it may have been possible to appreciate beneficial effect of LPD. It is our contention that in all cases of CKD that are slowly progressive, LPD can significantly retard progression of CKD and delay the need for renal replacement therapy (RRT). To be able to apply LPD for a long period, it is important to prescribe LPD at earlier stages (1,2,3) of CKD and not at late stage as recommended by KDIGO guidelines. Many clinicians are concerned about worsening nutritional status and hence reluctant to prescribe LPD. This actually is true for patients with advanced CKD in whom there is spontaneous decrease in calorie and protein intake. In our experience, nutritional status of patients in early stages (1,2,3) of CKD is as good as that of healthy subjects. Prescribing LPD at an early stage is unlikely to worsen status. The role of LPD in retarding progression of CKD is well established in animal experimental studies. Even in human subjects, there is enough evidence to suggest that LPD retards progression of CKD in carefully selected subjects. It should be prescribed to those with good appetite, good nutritional status and a slowly

    Foot-and-mouth disease virus (FMDV) causes an economically important and highly contagious disease of cloven-hoofed animals such as cattle, swine, and sheep. FMD vaccine is the traditional way to protect against the disease, which can greatly reduce its occurrence. However, the use of FMD vaccines to protect early infection is limited. Therefore, the alternative strategy of applying antiviral agents is required to control the spread of FMDV in outbreak situations. As previously reported, LiCl has obviously inhibition effects on a variety of viruses such as transmissible gastroenteritis virus (TGEV), infectious bronchitis coronavirus (IBV), and pseudorabies herpesvirus and EV-A71 virus. In this study, our findings were the first to demonstrate that LiCl inhibition of the FMDV replication. In this study, BHK-21 cell was dose-dependent with LiCl at various stages of FMDV. Virus titration assay was calculated by the 50% tissue culture infected dose (TCID 50 ) with the Reed and Muench method. The cytotoxicity assay of LiCl was performed by the CCK8 kit. The expression level of viral mRNA was measured by RT-qPCR. The results revealed LiCl can inhibit FMDV replication, but it cannot affect FMDV attachment stage and entry stage in the course of FMDV life cycle. Further studies confirmed that the LiCl affect the replication stage of FMDV, especially the early stages of FMDV replication. So LiCl has potential as an effective anti-FMDV drug. Therefore, LiCl may be an effective drug for the control of FMDV. Based on that, the mechanism of the antiviral effect of LiCl on FMDV infection is need to in-depth research in vivo. © 2017 Wiley Periodicals, Inc.

    Deficits in emotional processing can be detected in the pre-manifest stage of Huntington's disease and negative emotion recognition has been identified as a predictor of clinical diagnosis. The underlying neuropathological correlates of such deficits are typically established using correlative structural MRI studies. This approach does not take into consideration the impact of disruption to the complex interactions between multiple brain circuits on emotional processing. Therefore, exploration of the neural substrates of emotional processing in pre-manifest HD using fMRI connectivity analysis may be a useful way of evaluating the way brain regions interrelate in the period prior to diagnosis. We investigated the impact of predicted time to disease onset on brain activation when participants were exposed to pictures of faces with angry and neutral expressions, in 20 pre-manifest HD gene carriers and 23 healthy controls. On the basis of the results of this initial study went on to look at amygdala dependent cognitive performance in 79 Huntington's disease patients from a cross-section of disease stages (pre-manifest to late disease) and 26 healthy controls, using a validated theory of mind task: "the Reading the Mind in the Eyes Test" which has been previously been shown to be amygdala dependent. Psychophysiological interaction analysis identified reduced connectivity between the left amygdala and right fusiform facial area in pre-manifest HD gene carriers compared to controls when viewing angry compared to neutral faces. Change in PPI connectivity scores correlated with predicted time to disease onset (r=0.45, pneural networks underlying social cognition and emotional processing can be detected prior to clinical diagnosis in Huntington's disease. Connectivity between the amygdala and other brain regions is impacted by the disease process in pre-manifest HD and may therefore be a useful way of identifying participants who are approaching a clinical diagnosis

    1987-01-01

    Twenty-one patients with stage IB cervical cancer were treated with radical hysterectomy, pelvic lymph node dissection, and pelvic radiation therapy to approximately 5,090 rad. Patients were divided into two groups: group I, nine patients with involved parametria or positive margins at surgery; group II, 12 patients with metastatic pelvic lymph nodes. Patients in group I had an actuarial survival of 40% at 5 years and 20% at 10 years; patients in group II had an actuarial survival of 67% at 5 and 10 years (.01 < P < .05). The overall actuarial survival was 55% at 5 years and 43% at 10 years. Thus, patients with stage IB disease and involved parametrium or surgical margins do poorly. Alternative forms of therapy should be considered when this disease picture is clinically suspected preoperatively

    Pancreatitis with normal lipase and amylase level is a rare phenomenon. This is especially true in patient with end-stage renal disease as lipase and amylase are renally excreted. Literature review reveals previous case report of pancreatitis with normal lipase and amylase level, however, none of them occurred in the setting of end-stage renal disease. Our case is the first such reported case of pancreatitis in such setting. Here we report a 30year old male with past medical history of end-stage renal disease who presented in emergency department with acute abdominal pain. Laboratory work up revealed normal lipase and amylase level. However, radiological work up was consistent with pancreatitis. This case report highlight the importance of taking the overall clinical picture rather than laboratory work up to rule in or rule out the diagnosis of pancreatitis. Furthermore, this should also serve an important reminder for clinicians to further investigate where clinical suspicion for pancreatitis is high. Copyright © 2017 Elsevier Inc. All rights reserved.

  8. Computerised tomography in the staging of Hodgkin's disease and non-Hodgkin's lymphoma

    2003-01-01

    The last 25 years have seen major changes in the imaging investigation and subsequent management of patients with Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL); accurate staging is vital for prognostication and treatment in both, and particularly in HD. The choice of imaging modality for staging depends on its accuracy, impact on clinical decision-making, and availability. Modern CT scanners fulfil most of the desired criteria. The advent of CT scanning, along with the development of ever more effective chemotherapeutic regimens, has resulted in the virtual demise of bipedal lymphangiography (LAG) as a staging tool in patients with lymphoma. It has rendered superfluous a battery of other tests that were in routine use. This contribution reviews the evidence for the use of CT in preference to LAG. CT accurately depicts nodal enlargement above and below the diaphragm, has variable sensitivity for intra-abdominal visceral involvement and is generally outstanding in depicting the extent of disease, especially extranodal extension. Despite the advances in CT technology, there are still areas where CT performs less well (e.g. disease in normal-sized lymph nodes, splenic and bone marrow infiltration). The influence of technical factors, such as the use of intravenous contrast medium, is discussed. In some instances, CT is not the imaging modality of choice and the place of newer techniques such as MRI and endoscopic ultrasound will be reviewed. (orig.)

    Coronary artery disease (CAD) was evaluated by noninvasive examination in abdominal aortic aneurysm (AAA) patients. A simultaneous operation or a 2-staged operation was performed depending on the seriousness of the condition when both diseases were combined. A total of 36 patients underwent elective repair of AAA between 1996 and 2001. Coronary angiography (CAG) was performed only in patients with suspected CAD by dipyridamole myocardial scintigraphy. Significant CAD was found in 8 patients. Simultaneous operation was performed in 4 patients, and off-pump coronary artery bypass grafting (OPCAB) was performed in all cases of simultaneous operation. In 4 patients receiving 2-staged operations, 1 standard coronary artery bypass grafting (CABG), 1 OPCAB and 2 percutaneous transluminal coronary angioplasties (PTCA) were performed prior to AAA surgery. Twenty-eight patients underwent only AAA operation. Though there were no incidents of perioperative myocardial infarction or cardiac related deaths in this group, 2 patients died due to other causes (hemorrhage and duodenal perforation). In the 8 patients associated with CAD, 1 patient died of myonephrotic metabolic syndrome (MNMS) after simultaneous operation. The other 7 patients revived their social function soon of the discharge. Dipyridamole cardiac scintigraphy was considered to be an effective examination for evaluation of CAD in AAA patients. There was no need to perform CAG in all AAA patients. The policy of choosing simultaneous operation or 2-staged operation according to the seriousness of the 2 diseases seemed to be appropriate. (author)

    The coagulopathy of end-stage liver disease results from a complex derangement in both anticoagulant and procoagulant processes. With even minor insults, cirrhotic patients experience either inappropriate bleeding or clotting, or even both simultaneously. The various phases of liver transplantation along with fluid and blood product administration may contribute to additional disturbances in coagulation. Thus, anesthetic management of patients undergoing liver transplantation to improve hemostasis and avoid inappropriate thrombosis in the perioperative environment can be challenging. To add to this challenge, traditional laboratory tests of coagulation are difficult to interpret in patients with end-stage liver disease. Viscoelastic coagulation tests such as thromboelastography (Haemonetics Corporation, Braintree, MA) and rotational thromboelastometry (TEM International, Munich, Germany) have helped to reduce transfusion of allogeneic blood products, especially fresh frozen plasma, but have also lead to the increased use of fibrinogen-containing products. In general, advancements in surgical techniques and anesthetic management have led to significant reduction in blood transfusion requirements during liver transplantation. Targeted transfusion protocols and pharmacologic prevention of fibrinolysis may further aid in the management of the complex coagulopathy of end-stage liver disease.

    One hundred and one consecutive patients with newly diagnosed stage I Hodgkin's disease (HD) received treatment at St Bartholomew's Hospital, between 1968 and 1987, with a median follow-up of 12 years. Actuarial analysis predicts 78% to be alive and without relapse of Hodgkin's disease at 15 years. Ninety evaluable patients received either mantle or inverted 'Y' radiotherapy. Histology at presentation was nodular sclerosing (39), lymphocytic predominant (27) or mixed cellularity (24). The presenting site was neck (78), axilla (6) groin (4) and mediastinum (2). Complete remission was achieved in all evaluable patients, the actuarial proportion in remission being 75% at 15 years. Factors predictive of a prolonged remission were pathological staging versus clinical staging and lymph node size < 3 cm. Actuarial overall survival in these 90 patients was 75% at 15 years. Relapse of HD has occurred in 18 patients. Second remission was achieved in 15/18. The actuarial rate of second remission and survival was 40% at 10 years. Sixteen patients have died, 7 of Hodgkin's disease, 7 of unrelated causes and 2 of second malignancy. A further 3 patients who developed second malignancy are still alive. At 15 years the actuarial mortality related to HD was 12%. These results confirm the importance of long follow up to assess the efficacy of primary therapy. (author)

    Previous MRI studies have investigated cortical or subcortical grey matter changes in patients with Parkinson's disease (PD), yielding inconsistent findings between the studies. We therefore sought to determine whether focal cortical or subcortical grey matter changes may be present from the early disease stage. We recruited 49 untreated, early stage PD patients without dementia and 53 control subjects. Voxel-based morphometry was used to evaluate cortical grey matter changes, and automated volumetry and shape analysis were used to assess volume changes and shape deformation of the subcortical grey matter structures, respectively. Voxel-based morphometry showed neither reductions nor increases in grey matter volume in patients compared to controls. Compared to controls, PD patients had significant reductions in adjusted volumes of putamen, nucleus accumbens, and hippocampus (corrected p grey matter and clinical variables representing disease duration and severity. Our results suggest that untreated, early stage PD without dementia is associated with volume reduction and shape deformation of subcortical grey matter, but not with cortical grey matter reduction. Our findings of structural changes in the posterolateral putamen and ventromedial putamen/nucleus accumbens could provide neuroanatomical basis for the involvement of motor and limbic striatum, further implicating motor and non-motor symptoms in PD, respectively. Early hippocampal involvement might be related to the risk for developing dementia in PD patients. Copyright © 2014 Elsevier Ltd. All rights reserved.

Compare the rates of metastases in esophageal cancer patients undergoing EUS staging who require esophageal dilation in order to pass the echoendoscope versus those who do not. Methods. We reviewed consecutive patients referred for EUS staging of esophageal cancer. We evaluated whether dilation was necessary in order to pass the echoendoscope, and for the subsequent development of metastases after EUS at various time intervals. Results. Among all patients with similar stage (locally advanced disease, defined as T3, N0, M0 or T1-3, N1, M0, there was no difference between the dilated and nondilated groups in the rates of metastases at 3 months (14% versus 10%, =1.0, 6 months (28% versus 20%, =0.69, 12 months (43% versus 40%, =1.0, or ever during a mean followup of 15 months (71% versus 55%, =0.48. Conclusions. Dilation of malignant strictures for EUS staging of esophageal cancer does not appear to lead to higher rates of distant metastases.

  14. Improving prediction of Alzheimer’s disease using patterns of cortical thinning and homogenizing images according to disease stage

    Predicting Alzheimer’s disease (AD) in individuals with some symptoms of cognitive decline may have great influence on treatment choice and guide subject selection in trials on disease modifying drugs. Structural MRI has the potential of revealing early signs of neurodegeneration in the human brain...... and may thus aid in predicting and diagnosing AD. Surface-based cortical thickness measurements from T1-weighted MRI have demonstrated high sensitivity to cortical gray matter changes. In this study, we investigated the possibility of using patterns of cortical thickness measurements for predicting AD...... of conversion from MCI to AD can be improved by learning the atrophy patterns that are specific to the different stages of disease progression. This has the potential to guide the further development of imaging biomarkers in AD....

    Cardiovascular disease among hemodialysis (HD) patients is linked to poor outcomes. The Acute Dialysis Quality Initiative Workgroup proposed echocardiographic (ECHO) criteria for structural heart disease (SHD) in dialysis patients. The association of SHD with important patient outcomes is not well defined. This study sought to determine prevalence of ECHO-determined SHD and its association with survival among incident HD patients. We analyzed patients who began chronic HD from 2001 to 2013 who underwent ECHO ≤1 month prior to or ≤3 months following initiation of HD (n = 654). Mean patient age was 66 ± 16 years, and 60% of patients were male. ECHO findings that met 1 or more and ≥3 of the new criteria were discovered in 87% and 54% of patients, respectively. Over a median of 2.4 years, 415 patients died: 108 (26%) died within 6 months. Five-year mortality was 62%. Age- and sex-adjusted structural heart disease variables associated with death were left ventricular ejection fraction (LVEF) ≤45% (hazard ratio [HR]: 1.48; confidence interval [CI]: 1.20 to 1.83) and right ventricular (RV) systolic dysfunction (HR: 1.68; CI: 1.35 to 2.07). An additive of higher death risk included LVEF ≤45% and RV systolic dysfunction rather than neither (HR: 2.04; CI: 1.57 to 2.67; p = 0.53 for test for interaction). Following adjustment for age, sex, race, diabetic kidney disease, and dialysis access, RV dysfunction was independently associated with death (HR: 1.66; CI 1.34 to 2.06; p < 0.001). SHD was common in our HD study population, and RV systolic dysfunction independently predicted mortality. Copyright © 2016 American College of Cardiology Foundation. Published by Elsevier Inc.

  17. End-stage renal disease in Nigeria: An overview of the epidemiology and the pathogenetic mechanisms

    2011-01-01

    Full Text Available There is paucity of information on the magnitude of the burden of renal disease in our environment. Obtaining accurate data is hampered by the poor socioeconomic status of most patients with lack of access to specialized care in tertiary institutions, where most of the data is generated. The incidence of chronic renal failure (CRF and end-stage renal disease (ESRD in any specified area is known to be influenced by the prevalence of specific disease entities resulting in CRF. Hypertension, glomerulonephritis (GN, sickle cell disease, quartan malaria nephropathy, urinary tract schistosomiasis and other parasite-related forms of chronic GN are known to contribute significantly to the incidence of CRF in Nigeria. As is the situation in other parts of the world, diabetic nephropathy appears to be of increasing importance in the causation of ESRD in Nigeria. Even though the underlying cause of renal disease can often not be treated, extensive studies in experimental animals and preliminary studies in humans suggest that progression in chronic renal disease may largely be due to secondary factors, attention to which may be important in the prevention and/or control of renal disease.

    Full Text Available ABSTRACT Objective To investigate which factors are associated with the quality of life decline in Parkinson’s disease patients from mild to moderate stages. Methods The Unified Parkinson’s Disease Rating Scale and Parkinson’s Disease Questionnaire-39 were used to evaluate clinical/functional data and the quality of life. Results The markers of clinical/functional worsening were drooling (p < 0.004, need for assistance with hygiene (p = 0.02, greater freezing frequency (p = 0.042, bradykinesia (p = 0.031, greater intensity of the resting tremor (p = 0.035 and “pill rolling” (p = 0.001. The decline in quality of life was related to stigma (p = 0.043, greater impairment in cognition (p = 0.002, mobility (p = 0.013 and for daily living activities (p = 0.05, and was considered more significant in men, married, older individuals, and those with a longer time of disease. Conclusions The quality of life worsening markers at the moderate stage were related to stigma, worsening of cognition, and to greater impairment in mobility and daily living activities.

    The aim of the present study was to gain insight into the living and care situation in advanced behavioral variant frontotemporal dementia (bvFTD), to describe symptoms and findings in advanced bvFTD, and to evaluate somatic comorbidities and circumstances of death. Standardized interviews were conducted with family caregivers of 83 patients with bvFTD. Forty-four percent of the patients were already deceased at the time of the interview. At the time of the interview or death, respectively, 47% of the patients lived in a nursing home. The median time between symptom onset and nursing home admission was 5.0 ± 5.5 years. In moderate and severe dementia stages almost all patients suffered from severe disabilities including impairment of language, gait, swallowing, and of the ability to care for themselves. Sixteen percent of the patients had got enteral tube feeding. Comorbid somatic diseases were diagnosed in 46% of the patients. Twenty-three percent of the deceased patients had been admitted into a hospital before death. Cardiovascular disease and respiratory disease, mostly pneumonia, were the most frequent causes of death. Advanced bvFTD is characterized by severe cognitive impairment and physical disabilities. BvFTD leads to a premature death. Our findings stress the importance of strategies that maximize patient comfort in advanced disease stages and allow for a peaceful death. Copyright © 2016 John Wiley & Sons, Ltd.

    Full Text Available Cardiovascular disease (CVD and chronic kidney disease (CKD are common comorbid conditions. Life style, particularly diet is a critical component of treatment for these conditions. Register dietitians play a key role in bridging the gap between the science of nutrition and the empowerment of individuals to alter their lifestyles in a healthy manner. A range of dietary manipulations has been reported to reduce risk factors and decrease risk of CVD and CKD outcomes. However, many studies provided food to participants or were limited to adjustment of few specific nutrients. Diet intervention in relation with end-stage renal disease (ESRD is really complicated topic. As multiple co morbid conditions such as hypertension, CVD, CKD, and diabetes mellitus (DM are associated with ESRD, which made the scenario really worse while fixing the dose of any diet. Still a lot of research work is required to understand this topic.

    Eradication of a disease is one of the greatest gifts any generation can give to subsequent ones, but most attempts have failed. The biggest challenges occur in the final stages of eradication and elimination campaigns. These include falling public support as a disease becomes less common; the emergence of groups who do not support eradication; spiralling costs; and the evolution of drug, vaccine or insecticide resistance. Mass campaigns become less effective as the disease fragments and modelling becomes less reliable. Optimism bias is the biggest risk to any eradication campaign and the long endgame must be planned for from the beginning. © The Author 2015.

    2016-01-01

    Hyperphosphatemia, hypocalcemia and vitamin D deficiency are the main factors involved in the pathogenesis of secondary hyperparathyroidism (SHPT). Moreover, the skeletal resistance to parathyroid hormone is not only a high-turnover bone accompanying SHPT, but may also play a crucial role in the onset of low-turnover bone disease in uremia. However, a growing body of evidence suggests that other hormones play a key role in this disease, such as fibroblast growth factor 23, Klotho and sclerostin. SHPT causes both bone-associated and non-skeletal consequences, including cardiovascular calcifications. Furthermore, vitamin D and calcium (Ca)-containing phosphate binders may increase Ca load. Anyway, the rate of parathyroidectomy in end-stage renal disease has greatly decreased during the last decade. Is there any room left for surgeons? © 2016 S. Karger AG, Basel.

  3. The patient, disease status, and treatment options for prostate cancer: stages B1 and B2

    Prostatic adenocarcinoma palpably confined to the prostate is clinically defined as stage B. Although potentially curable in many, if not most, instances, there is no disputing that the optimal management of patients with stage B neoplasms is one of the most uncertain and controversial issues in modern urologic oncology. The present uncertainty can be related to three major factors: 1) competing causes of death in patients commonly older than 50 years of age; 2) the variable and unpredictable natural course of localized prostatic cancer as reflected by the three, at least in part, independent variables of growth rate, metastatic potential, and therapeutic responsiveness; and 3) the multiplicity and effectiveness of a variety of treatments in producing effects on the tumor favorable to the patient. The relative effectiveness of different treatments has been and remains clouded by a constantly changing array of clinical staging techniques, selection criteria for treatment, and definitions of response, and by the general absence of satisfactory control data. Experiences with patients receiving no treatment, various forms of irradiation, and radical excision have indicated a general similarity in at least 10-year survival rates and clinically manifest local failure rates among comparable substages of stage B prostatic cancer. Since suitable control data are lacking, one may conclude that a variety of treatments offer similar prospects of benefit or that none of the treatments is producing significant beneficial effect and that survivals are a consequence of the natural history of stage B disease. A Possibility that has yet to be evaluated is that different treatments produce benefit in different segments of the stage B prostatic cancer population, and the challenge today is to recognize and define such neoplasms that may respond most appropriately to one form of therapy or another

    Huntington disease (HD) results in a range of cognitive and motor impairments that progress throughout the disease stages; however, little research has evaluated specific dual-task abilities in this population, and the degree to which they may be related to functional ability. The purpose of this study was to a) examine simple and complex motor-cognitive dual-task performance in individuals with HD, b) determine relationships between dual-task walking ability and disease-specific measures of motor, cognitive and functional ability, and c) examine the relationship of dual-task measures to falls in individuals with HD. Thirty-two individuals with HD were evaluated for simple and complex dual-task ability using the Walking While Talking Test. Demographics and disease-specific measures of motor, cognitive and functional ability were also obtained. Individuals with HD had impairments in simple and complex dual-task ability. Simple dual-task walking was correlated to disease-specific motor scores as well as cognitive performance, but complex dual-task walking was correlated with total functional capacity, as well as a range of cognitive measures. Number of prospective falls was moderately-strongly correlated to dual-task measures. Our results suggest that individuals with HD have impairments in cognitive-motor dual-task ability that are related to disease progression and specifically functional ability. Dual-task measures appear to evaluate a unique construct in individuals with early to mid-stage HD, and may have value in improving the prediction of falls risk in this population.

    To see the various hematological changes in the bone marrow of patients with chronic kidney disease (CKD) stage III, IV and V. Study Design: Cross sectional observational study.Place and Duration of Study: Study was conducted in the department of haematology (Pathology), Army Medical College, Rawalpindi and duration was one year, from Mar 2015 to Feb 2016. Material and Methods: Patients of both sexes and all age groups with CKD stage III, IV and V were included in this study. Patients' histories were recorded. Complete blood counts, bone marrow aspiration and trephine biopsy were done and evaluated microscopically. Mean blood counts of the patients in three groups of CKD were compared. Frequencies of various bone marrow (BM) findings in patients of CKD were calculated. Results: Out of 57 patients, 41 (71.9%) were males while 16 (28%) were females. Mean age was 60 years. There was no statistically significant difference between the mean hemoglobin, mean white cell count and mean platelets count of the patients in three groups of CKD. Reactive changes due to underlying CKD and inflammation were the most frequent findings in the BM of the patients. Conclusion: Anaemia of mild to moderate severity and reactive changes in the BM are the most frequent haematological findings encountered in patients suffering from advanced stage CKD. Since CKD is predominantly a disease of the elderly so it is not rare to find the co-morbidities including plasmacytosis, malignancies and their effects on the BM in patients of CKD. (author)

  6. Fetal Origins of Life Stage Disease: A Zebrafish Model for the ...

    Science.gov (United States)

    In the U.S., childhood obesity has more than doubled in children and quadrupled in adolescents in the past 30 years, affects 35% of adults, and costs the U.S. healthcare industry >$200 billion annually. The chemical environment in the womb may cause susceptibility to different life-stage and life-long metabolic diseases including obesity. The challenge is to understand if exposures during developmentally sensitive windows impact life-stage disease, such as obesity, by increasing adipose tissue mass. In vitro models lack the integrated systems approach needed to assess adipose development, while mammalian models are impractical in a screen of thousands of chemicals. Therefore, an obesogen screening method was developed to interrogate bioactivity using a full systems approach, in a vertebrate zebrafish model with complete metabolic activity, at a time when the full signaling repertoire is expressed and active, to optimally examine how chemical dose and duration impact life-stage adipose mass. A time-line for adipose depot formation was mapped in zebrafish 6−14 days post fertilization (dpf) using the lipophilic dye, Nile Red, in combination with fluorescent microscopy. Those time points were then used to investigate the impact of embryonic tributyltin chloride (TBT, a known obesogen) exposure (10nM daily renewal, 0−5dpf) on adipose mass. Fluorescent microscopy revealed adipose depots that were larger and appeared 2 days earlier in TBT treated compared to contro

    Fifty-two patients with pathologic stage III Hodgkin's disease were studied in an effort to determine whether location of involved abdominal nodes influenced survival. Treatment consisted of total nodal radiotherapy with or without subsequent combination chemotherapy. The initial radiation field was the ''extended mantle,'' which included supradiaphragmatic nodes, the splenic hilar area, and paraaortic nodes to the level of L2-L4. Subsequently, lower paraaortic and iliac regions were treated (''lower inverted Y''). Patients with disease limited to the spleen and/or splenic, celiac, or portal nodes (''anatomic substage'' III/sub 1/) had a more favorable 5-yr survival than did patients with involvement of paraaortic, iliac, or mesenteric nodes (''anatomic substage'' III/sub 2/) : 93% versus 57%, respectively (p < 0.05). The addition of combination chemotherapy to total nodal irradiation was associated with improved survival of patients in stage III/sub 2/, but not of those in stage III/sub 1/.

    The diagnostic paradigm of Alzheimer disease (AD) is changing; there is a trend toward diagnosing the disease in its early stages, even before the complete syndrome of dementia is apparent. The clinical stage at which AD is usually diagnosed in our area is unknown. Therefore, the purpose of this study is to describe the clinical stages of AD patients at time of diagnosis. Multicentre, observational and cross-sectional study. Patients with probable AD according to NINCDS-ARDRA criteria, attended in specialist clinics in Spain, were included in the study. We recorded the symptom onset to evaluation and symptom onset to diagnosis intervals and clinical status of AD (based on MMSE, NPI questionnaire, and CDR scale). Participants in this study included 437 specialists representing all of Spain's autonomous communities and a total of 1,707 patients, of whom 1,694 were included in the analysis. Mean MMSE score was 17.6±4.8 (95% CI:17.4-17.9). Moderate cognitive impairment (MMSE between 10 and 20) was detected in 64% of the patients, and severe cognitive impairment (MMSEde Neurología.

    The objectives of this study were to assess the prevalence of chronic obstructive pulmonary disease (COPD) in hemodialysis patients with spirometry and to examine the effects of fluid removal by hemodialysis on lung volumes. Patients ≥18 years at two Danish hemodialysis centers were included....... Forced expiratory volume in one second (FEV1 ), forced vital capacity (FVC), and FEV1 /FVC ratio were measured with spirometry before and after hemodialysis. The diagnosis of COPD was based on both the GOLD criteria and the lower limit of normal criteria. There were 372 patients in treatment at the two...... centers, 255 patients (69%) completed spirometry before dialysis and 242 of these (65%) repeated the test after. In the initial test, 117 subjects (46%) had airflow limitation indicative of COPD with GOLD criteria and 103 subjects (40.4%) with lower limit of normal criteria; COPD was previously diagnosed...

    Cardiovascular (CV) disease is the leading cause of death in chronic kidney disease (CKD) and end-stage renal disease (ESRD). A key driver in this pathology is increased aortic stiffness, which is a strong, independent predictor of CV mortality in this population. Aortic stiffening is a potentially modifiable biomarker of CV dysfunction and in risk stratification for patients with CKD and ESRD. Previous work has suggested that therapeutic modification of aortic stiffness may ameliorate CV mortality. Nevertheless, future clinical implementation relies on the ability to accurately and reliably quantify stiffness in renal disease. Pulse wave velocity (PWV) is an indirect measure of stiffness and is the accepted standard for non-invasive assessment of aortic stiffness. It has typically been measured using techniques such as applanation tonometry, which is easy to use but hindered by issues such as the inability to visualize the aorta. Advances in cardiac magnetic resonance imaging now allow direct measurement of stiffness, using aortic distensibility, in addition to PWV. These techniques allow measurement of aortic stiffness locally and are obtainable as part of a comprehensive, multiparametric CV assessment. The evidence cannot yet provide a definitive answer regarding which technique or parameter can be considered superior. This review discusses the advantages and limitations of non-invasive methods that have been used to assess aortic stiffness, the key studies that have assessed aortic stiffness in patients with renal disease and why these tools should be standardized for use in clinical trial work.

    Better treatment during early stages of chronic kidney disease (CKD) may slow progression to end-stage renal disease and decrease associated complications and medical costs. Achieving early treatment of CKD is challenging, however, because a large fraction of persons with CKD are unaware of having this disease. Screening for CKD is one important method for increasing awareness. We examined the cost-effectiveness of identifying persons for early-stage CKD screening (i.e., screening for moderate albuminuria) using published CKD risk scores. We used the CKD Health Policy Model, a micro-simulation model, to simulate the cost-effectiveness of using CKD two published risk scores by Bang et al. and Kshirsagar et al. to identify persons in the US for CKD screening with testing for albuminuria. Alternative risk score thresholds were tested (0.20, 0.15, 0.10, 0.05, and 0.02) above which persons were assigned to receive screening at alternative intervals (1-, 2-, and 5-year) for follow-up screening if the first screening was negative. We examined incremental cost-effectiveness ratios (ICERs), incremental lifetime costs divided by incremental lifetime QALYs, relative to the next higher screening threshold to assess cost-effectiveness. Cost-effective scenarios were determined as those with ICERs less than $50,000 per QALY. Among the cost-effective scenarios, the optimal scenario was determined as the one that resulted in the highest lifetime QALYs. ICERs ranged from $8,823 per QALY to $124,626 per QALY for the Bang et al. risk score and $6,342 per QALY to $405,861 per QALY for the Kshirsagar et al. risk score. The Bang et al. risk score with a threshold of 0.02 and 2-year follow-up screening was found to be optimal because it had an ICER less than $50,000 per QALY and resulted in the highest lifetime QALYs. This study indicates that using these CKD risk scores may allow clinicians to cost-effectively identify a broader population for CKD screening with testing for albuminuria

    2011-09-01

    Patients with chronic kidney disease (CKD) often experience a decline in their nutrient intake starting at early stages of CKD. This reduction in intake can affect both energy-producing nutrients, such as carbohydrates, proteins, and fats, as well as vitamins, minerals, and trace elements. Knowledge of the burden and bioactivity of vitamins and their effect on the health of the patients with CKD is very incomplete. However, without sufficient data, the use of nutritional supplements to prevent inadequate intake may result in either excessive or insufficient intake of micronutrients for people with CKD. The purpose of this article is to briefly summarize the current knowledge regarding vitamin requirements for people with stages 3, 4, or 5 CKD who are not receiving dialysis.

    2014-11-01

    The increasing prevalence of obesity places ever-increasing cost demands on healthcare systems. One million individuals are eligible for bariatric surgery in the UK, and yet less than 6000 bariatric procedures are performed annually. Bariatric surgery reverses or improves almost all the medical and psychosocial co-morbidities associated with obesity. Although the BMI is a simple method to estimate adiposity at a population level, it is relatively inaccurate within an individual and provides little-to-no indication of overall health status or disease severity. Staging systems overcome the inherent limitations of BMI and allow highly informed decision-making for an individual. At a societal level, this helps to identify those most likely to gain and maximise economic benefit. This review summarises the co-morbidities associated with obesity and the evidence for their improvement following surgery. The rationale for new staging criteria and appropriate patient selection are discussed.

    To suggest a behavioural research agenda for patients with end-stage renal disease (ESRD) based on a concise review of seven stages of psychosocial research, a literature review, and current behavioural research in other chronic somatic diseases. Historical behavioural ESRD research was classified. The specialized register of the Cochrane Behavioral Medicine Field was also checked, and additional papers were selected by screening reference lists and related behavioural science journals, to identify promising areas for future research. The top-five topics identified via the literature search pertain to (1) psychological aspects and interventions, (2) adaptation, coping, and depression, (3) exercise, (4) counseling and education, and (5) compliance. 'Illness and treatment beliefs', 'sexuality', 'suicide', 'family support', and 'self-management interventions', were identified on the basis of research in other chronic illnesses as topics for future research. Regarding theory, the Common-Sense Model (CSM) was judged to offer useful theoretical perspectives; regarding methods, qualitative methods can be a valuable addition to quantitative research methods. Illness beliefs, treatment beliefs, and self-management behaviours are promising concepts in the assessment and clinical care of ESRD-patients. Cognitive-behavioural treatments appear to have potential and should be specified and elaborated for specific categories and problems of ESRD-patients. This research agenda is in line with moves towards patient-centred disease-management to improve the quality of medical care for ESRD-patients. (c) 2009 Elsevier Ireland Ltd. All rights reserved.

    2015-07-01

    Full Text Available Parkinson's disease (PD is a devastating age related neurodegenerative disease that is believed to have a lengthy prodromal state. It is critical to find methods of interfering with the progression of this early degenerative stage by inducing compensatory recovery processes to slow or prevent the eventual clinical symptoms. The current perspective article argues that immune system signalling molecules represent such a promising therapeutic approach. Two cytokines of interest are granulocyte macrophage-colony stimulating factor (GM-CSF and erythropoietin (EPO. These hematopoietic cytokines have been protective in models of stroke, neuronal injury, and more recently PD. It is our belief that these trophic cytokines can be used not only for cell protection but also regeneration. However, success is likely dependent on early intervention. This paper will outline our perspective on the development of novel trophic recovery treatments for PD. In particular, we present new data from our lab suggesting that EPO and GM-CSF can foster neural re-innervation in a mild or partial lesion PD model that could be envisioned as reflecting the early stages of the disease.

    The present study investigated differences and associations between cortical perfusion, nigrostriatal dopamine pathway and neuropsychological functions in different stages of Parkinson's disease (PD). We recruited 53 non-demented PD patients divided into four groups according to the Hoehn and Yahr (HY) staging system and 20 healthy controls who were used in the comparison of the neuropsychological findings. Each patient underwent two separate brain single photon emission computed tomography (SPECT) studies (perfusion and dopamine transporter binding) as well as neuropsychological evaluation. Perfusion images of each patient were quantified and compared with a normative database provided by the NeuroGam software manufacturers. Mean values obtained from the cortical areas and neuropsychological measures in the different groups were also compared by analysis of covariance (ANCOVA) controlling for disease duration and educational level. We found cognitive deficits especially in the late PD stages (HY 3, 4 and 5) compared to the early stages (HY 1 and 2) and associations between cognitive decrements and cortical perfusion deterioration mainly in the frontal and posterior cortical areas. Compared with controls, PD patients showed impairments of cognition and cerebral perfusion that increased with clinical severity. Furthermore, we found a significant correlation between the performance on the phonemic fluency task and regional cerebral blood flow (rCBF) in the left frontal lobe. Dopamine transporter binding in the left caudate nucleus significantly correlated with blood flow in the left dorsolateral prefrontal cortex (DLPFC), but not with measures of executive functions. There are significant cognitive and perfusion deficits associated with PD progression, implying a multifactorial neurodegeneration process apart from dopamine depletion in the substantia nigra pars compacta (SNc).

    Background Primary care is recognised to have an important role in the delivery of care for people with chronic kidney disease (CKD). However, there is evidence that CKD management is currently suboptimal, with a range of practitioner concerns about its management. Aim To explore processes underpinning the implementation of CKD management in primary care. Design and setting Qualitative study in general practices participating in a chronic kidney disease collaborative undertaken as part of the National Institute for Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care (CLAHRC) for Greater Manchester. Method Semi-structured interviews were conducted with GPs and practice nurses (n = 21). Normalisation Process Theory provided a framework for generation and analysis of the data. Results A predominant theme was anxiety about the disclosure of early-stage CKD with patients. The tensions experienced related to identifying and discussing CKD in older people and patients with stage 3A, embedding early-stage CKD within vascular care, and the distribution of work within the practice team. Participants provided accounts of work undertaken to resolve the difficulties encountered, with efforts having tended to focus on reassuring patients. Analysis also highlighted how anxiety surrounding disclosure influenced, and was shaped by, the organisation of care for people with CKD and associated long-term conditions. Conclusion Offering reassurance alone may be of limited benefit, and current management of early-stage CKD in primary care may miss opportunities to address susceptibility to kidney injury, improve self-management of vascular conditions, and improve the management of multimorbidity.

    Appendectomy was performed at primary or secondary staging operations in 100 patients with ovarian malignancies. Of 80 patients who underwent appendectomy at the time of their primary surgery, 25 (31.2%) had appendiceal metastases. Among 47 patients who were believed to have disease limited to the pelvis at the time of surgery--stage I (N = 34), II (N = 7), IIIA (N = 5), and those designated stage IIIC solely on the basis of microscopic para-aortic nodal metastasis (N = 1)--the appendix was involved with disease in only two patients (4.3%). However, among 33 patients with advanced disease--stage IIIB (N = 6), IIIC except those designated IIIC solely on the basis of microscopic paraaortic nodal metastasis (N = 19), and IV (N = 8)--the appendix was involved with disease in 23 patients (69.7%) (P less than .001). Poorly differentiated tumors and serous histologic cell types more frequently metastasized to the appendix (64, 15, 6, and 8% for grades 3, 2, and 1 and borderline histology, respectively; P less than .001; and 48, 13, and 8% for serous, endometrioid, and mucinous; P less than .001). Of 20 patients who underwent appendectomy at their secondary staging procedure, two had metastases. Metastatic disease in the appendix was microscopic in nine of 27 patients. Because the frequency of appendiceal metastasis is similar to that of other metastatic sites in stages I and II ovarian cancer, it should be removed at primary staging procedures. Appendectomy should also be performed in patients with advanced ovarian malignancies if it contributes to cytoreduction or at the time of secondary staging procedures.

    Radioiodine (RAI) is a cornerstone in the treatment of Differentiated Thyroid Cancer (DTC). In patients on haemodialysis due to End-Stage Renal Disease (ESRD), it must be used cautiously, considering the renal clearance of this radionuclide. Also, the safety of the procedure and subsequent long-term outcome is still not well defined. In 2001, we described a dosimetric method and short-term results in three patients, with a good safety profile. We hypothesize that our method is safe in a long-term scenario without compromising the prognosis of both renal and thyroid disease. Descriptive-retrospective study. A systematic search was carried out using our clinical database from 2000 to 2014. DTC and radioiodine treatment while on haemodialysis. peritoneal dialysis. Final sample n=9 patients (n=5 males), age 48 years (median age 51 years males, 67 years female group); n=8 papillary thyroid cancer, n=1 follicular thyroid cancer; n=5 lymph node invasion; n=1 metastatic disease. Median RAI dose administered on haemodialysis 100mCi. 7.5 years after radioiodine treatment on haemodialysis, n=7 deemed free of thyroid disease, n=1 persistent non-localised disease. No complications related to the procedure or other target organs were registered. After 3.25 years, n=4 patients underwent successful renal transplantation; n=4 patients did not meet transplantation criteria due to other conditions unrelated to the thyroid disease or its treatment. One patient died due to ischemic cardiomyopathy (free of thyroid disease). Radioiodine treatment during haemodialysis is a long-term, safe procedure without worsening prognosis of either renal or thyroid disease. Copyright © 2015 Elsevier España, S.L.U. and SEMNIM.

    Objective: To evaluate the prevalence of renal failure (RF) in the patients of end stage liver disease (ESLD), to determine the causes of RF in these patients and its impact on patient's outcome. Study Design: Descriptive, analytical study. Place and Duration of Study: Shifa International Hospital, Islamabad, Pakistan, from May 2011 to March 2013. Methodology: A total of 523 patients with end stage liver disease (ESLD) were evaluated, renal failure (RF) and its causes were recognized in these patients according to established criteria. Outcome of these patients was assigned as reversal of RF or mortality. Data was analyzed using SPSS version 16. Chi-square test was used for comparing proportions and t-test was used for comparing mean values. P < 0.05 was considered significant. Results: Out of 523 patients, 261 (49.9%) had RF. Acute kidney injury (AKI) was the most common presentation seen in 160 (61%) patients. Hypovolemia and infections were the most frequent causes of RF. Mortality was significantly higher in the patients with RF, when compared to the patients without RF (31% vs. 4.5%, p < 0.001). Reversal of RF was seen in 98 (37%) of the affected patients. Reversal was more common in the patients with hypovolemia. The mortality was higher in the patients with hepatorenal syndrome (HRS) and infections. Conclusion: Renal failure in the end stage liver disease is an important prognostic factor. Etiology of RF is the key factor in patients' outcome. Patients of ESLD with RF had higher mortality. Majority of the cases of RF were reversible in patients of ESLD coming in the setup. (author)

    Parkinson's disease (PD) is known to affect postural control, especially in situations needing a change in balance strategy or when a concurrent task is simultaneously performed. However, few studies assessing postural control in patients with PD included homogeneous population in late stage of the disease. Thus, this study aimed to analyse postural control and strategies in a homogeneous population of patients with idiopathic advanced (late-stage) PD, and to determine the contribution of peripheral inputs in simple and more complex postural tasks, such as sensory conflicting and dynamic tasks. Twenty-four subjects with advanced PD (duration: median (M)=11.0 years, interquartile range (IQR)=4.3 years; Unified Parkinson's Disease Rating Scale (UPDRS): M "on-dopa"=13.5, IQR=7.8; UPDRS: M "off-dopa"=48.5, IQR=16.8; Hoehn and Yahr stage IV in all patients) and 48 age-matched healthy controls underwent static (SPT) and dynamic posturographic (DPT) tests and a sensory organization test (SOT). In SPT, patients with PD showed reduced postural control precision with increased oscillations in both anterior-posterior and medial-lateral planes. In SOT, patients with PD displayed reduced postural performances especially in situations in which visual and vestibular cues became predominant to organize balance control, as was the ability to manage balance in situations for which visual or proprioceptive inputs are disrupted. In DPT, postural restabilization strategies were often inefficient to maintain equilibrium resulting in falls. Postural strategies were often precarious, postural regulation involving more hip joint than ankle joint in patients with advanced PD than in controls. Difficulties in managing complex postural situations, such as sensory conflicting and dynamic situations might reflect an inadequate sensory organization suggesting impairment in central information processing.

    Healthy diet and physical activity are the treatment cornerstones of non-alcoholic fatty liver disease (NAFLD); their effectiveness is however limited by difficulties in implementing lifestyle changes. We aimed at determining the stage of change and associated psychological factors as a prerequisite to refine strategies to implement behavior changes. We studied 138 consecutive NAFLD patients (73% male, age 19-73 years). The diagnosis was confirmed by liver biopsy in 64 cases (steatohepatitis, 47%). All cases completed the validated EMME-3 questionnaire, consisting of two parallel sets of instruments (for diet and physical activity, respectively) and providing stages of change according to transtheoretical model. Logistic regression analysis was used to identify factors associated with stages making behavioral changes more demanding. The individual profiles were variable; for diet, no cases had precontemplation as prevalent stage of change (highest score in individual profiles); 36% had contemplation. For physical activity, 50% were classified in either precontemplation or contemplation. Minor differences were recorded in relation to associated metabolic complications or steatohepatitis. Logistic regression identified male sex (odds ratio, 4.51; 95% confidence interval, 1.69-12.08) and age (1.70; 1.20-2.43 per decade) as the independent parameters predicting precontemplation or contemplation for diet. No predictors were identified for physical activity. NAFLD cases have scarce readiness to lifestyle changes, particularly with regard to physical activity. Defining stages of change and motivation offers the opportunity to improve clinical care of NAFLD people through individual programs exploiting the powerful potential of behavioral counseling, an issue to be tested in longitudinal studies.

    Full Text Available Introduction: Primary single-stage pull-through for Hirschsprung′s disease (HD has been reported to give comparable surgical outcomes to staged operations with less morbidity. Herein, we present our experience with single-stage Modified Duhamel procedure for management of HD. Patients and Methods: This was a review of 48 cases of HD who underwent single-stage Modified Duhamel procedure without a protective colostomy. Results: The age at surgery ranged from 6 months to 10 years (median - 9 months, mean - 2.3 years. The average weight of the child was 7.2 kg (range, 4.9-22 kg. 38 (79.2% patients had classical rectosigmoid HD, the rest being long segment HD (the proximal most level being the splenic flexure. The average duration of surgery was 175 minutes (range, 130-245 minutes. The average blood loss was 45 ml. The average hospital stay was 7.2 days (range: 6-10 days. The major postoperative complications (n=3 included postoperative adhesive intestinal obstruction, anastomotic leak and persistent constipation due to residual aganglionosis. Each required a re-exploration. Minor complications included surgical site infection (n=3 and post-operative enterocolitis (n=3, which were managed conservatively. Six patients had constipation for a limited period post-operatively. All patients have a satisfactory functional outcome and normal development and growth. Conclusions: For HD, we recommend that single-stage Modified Duhamel procedure should be the preferred approach in view of its low morbidity, satisfactory functional outcome and avoidance of stoma, multiple surgeries and economic benefit in view of decreased hospital stay.

    The objective of this study was to compare the diagnostic accuracy of positron emission tomography/low-dose computed tomography (PET/ldCT) versus the same technique implemented by contrast-enhanced computed tomography (ceCT) in staging Hodgkin's disease (HD).Forty patients (18 men and 22 women, mean age 30 ± 9.6) with biopsy-proven HD underwent a PET/ldCT study for initial staging including an unenhanced low-dose computed tomography for attenuation correction with positron emission tomography acquisition and a ceCT, performed at the end of the PET/ldCT scan, in the same exam session. A detailed datasheet was generated for illness locations for separate imaging modality comparison and then merged in order to compare the separate imaging method results (PET/ldCT and ceCT) versus merged results positron emission tomography/contrast-enhanced computed tomography (PET/ceCT). The nodal and extranodal lesions detected by each technique were then compared with follow-up data that served as the reference standard.No significant differences were found at staging between PET/ldCT and PET/ceCT in our series. One hundred and eighty four stations of nodal involvement have been found with no differences in both modalities. Extranodal involvement was identified in 26 sites by PET/ldCT and in 28 by PET/ceCT. We did not find significant differences concerning the stage (Ann Arbor).Our study shows a good concordance and conjunction between PET/ldCT and ceCT in both nodal and extranodal sites in the initial staging of HD, suggesting that PET/ldCT could suffice in most of these patients.

    Full Text Available Ideally, disease modifying therapies for Alzheimer disease (AD will be applied during the 'preclinical' stage (pathology present with cognition intact before severe neuronal damage occurs, or upon recognizing very mild cognitive impairment. Developing and judiciously administering such therapies will require biomarker panels to identify early AD pathology, classify disease stage, monitor pathological progression, and predict cognitive decline. To discover such biomarkers, we measured AD-associated changes in the cerebrospinal fluid (CSF proteome.CSF samples from individuals with mild AD (Clinical Dementia Rating [CDR] 1 (n = 24 and cognitively normal controls (CDR 0 (n = 24 were subjected to two-dimensional difference-in-gel electrophoresis. Within 119 differentially-abundant gel features, mass spectrometry (LC-MS/MS identified 47 proteins. For validation, eleven proteins were re-evaluated by enzyme-linked immunosorbent assays (ELISA. Six of these assays (NrCAM, YKL-40, chromogranin A, carnosinase I, transthyretin, cystatin C distinguished CDR 1 and CDR 0 groups and were subsequently applied (with tau, p-tau181 and Aβ42 ELISAs to a larger independent cohort (n = 292 that included individuals with very mild dementia (CDR 0.5. Receiver-operating characteristic curve analyses using stepwise logistic regression yielded optimal biomarker combinations to distinguish CDR 0 from CDR>0 (tau, YKL-40, NrCAM and CDR 1 from CDR<1 (tau, chromogranin A, carnosinase I with areas under the curve of 0.90 (0.85-0.94 95% confidence interval [CI] and 0.88 (0.81-0.94 CI, respectively.Four novel CSF biomarkers for AD (NrCAM, YKL-40, chromogranin A, carnosinase I can improve the diagnostic accuracy of Aβ42 and tau. Together, these six markers describe six clinicopathological stages from cognitive normalcy to mild dementia, including stages defined by increased risk of cognitive decline. Such a panel might improve clinical trial efficiency by guiding

    Patients presenting with an exacerbation of chronic obstructive pulmonary disease (COPD) are initially assessed to ensure that a proper diagnosis has been made and that relevant differential diagnoses are excluded. Although guidelines provide indicators for use, very little systematic research has...... been done in initial assessment of COPD exacerbations. Next, the assessment should aim at stratifying patients for risk of poor outcome. For this, predictors of poor prognosis as well as knowledge of favorable treatments can be used. However, no formal and validated staging system exists today. Given...... the frequency and impact of COPD exacerbations, there seems to be a need for systematic research in this area....

    Full Text Available This questionnaire-based study included 69 patients from the Republic of Guinea with end-stage renal disease (ESRD and was conducted over 12 months. The factors that affected their quality of life (QoL were determined. The included ESRD patients had an estimated creatinine clearance (CCr of 4, P = 0.01. Good QoL was associated with younger age, fewer comorbidities, less severe physical pain, and fewer physical or social limitations. QoL could be increased by improving comorbidity treatments, giving more effective pain control, and providing more assistance for social and physical limitations.

    Cast nephropathy is the most common manifestation of renal injury in patients with multiple myeloma but is rarely reported in other conditions. We are reporting our experience in caring for a teenager with a metastatic neuroendocrine carcinoma who developed rapidly progressive kidney injury that advanced to end-stage renal disease. On renal biopsy extensive tubular necrosis and intratubular eosinophilic casts were noted. This previously unreported finding should prompt oncologists to closely monitor for such a complication in patients with secretory tumors. Whether early plasmapheresis could be of benefit, as has been tried in multiple myeloma, remains to be determined.

    Severe pulmonary hypertension in a teenager with end-stage renal disease on chronic hemodialysis via arteriovenous access is reported. Clinical presentation included persistent volume overload and pericardial effusion. Serial hemodynamic data obtained at cardiac catheterization confirmed the diagnosis. In addition, detailed biochemical and imaging data (echo- Doppler, computed tomography of chest, computed tomographic pulmonary angiography, VQ lung scan, etc.) were obtained to find out the mechanism. The exact cause of pulmonary hypertension remains unclear, and a multi- factorial mechanism is postulated. This rare case is presented to highlight the role of aggressive dialysis, pericardiocentesis, and use of sildenafil and bosentan in the management

    Full Text Available Background: Metabolic acidosis, a common condition particularly in the end-stage of renal disease patients, results in malnutrition, inflammation and oxidative stress. In this study, we focused on the association between low serum bicarbonate and cardiovascular disease in patients on intermittent dialysis. Methods: We studied 52 on-line-pre-dilution hemodiafiltration (on-l HDF patients, 32 males and 20 females, with a mean age of 58.01 ± 15.4 years old. Metabolic acidosis was determined by serum bicarbonate concentrations less than 22 mmol/L. Residual renal function (RRF was defined by interdialytic urine volume. Kaplan–Meier curves and Cox regression models were performed to predict coronary artery disease (CAD, defined by ejection fraction <50%, or diastolic dysfunction congestive heart failure (CHF and peripheral vascular disease (PVD. Results: Kaplan–Meier analyses showed that a lower or higher than 22 mmol/L serum bicarbonate metabolic acidosis status was significantly associated with both PVD and diastolic dysfunction (log-rank = 5.07, p = 0.02 and log-rank = 5.84, p = 0.01, respectively. A similar prevalence of serum bicarbonate on CAD or CHF by low ejection fraction was not shown. The RRF was associated with PVD event and serum bicarbonate less than 22 mmol/L (log-rank = 5.49, p = 0.01 and log-rank = 3.9, p = 0.04, respectively. Cox regression analysis revealed that serum bicarbonate and RRF were significant risk factors for PVD after adjustment for confounders. Furthermore, RRF adjusted for covariates was shown to be a significant risk factor for diastolic dysfunction. Conclusion: Low serum bicarbonate was associated with peripheral vascular disease and diastolic dysfunction in intermittent dialysis. The residual renal function may impact patients’ outcomes through its relationship with metabolic acidosis status, particularly for peripheral vascular disease manifestation.

    2010-11-01

    To review prevalence, causes and management of end-stage renal disease (ESRD) in sub-Saharan Africa (SSA). Review of literature and data. Approximately 70% of the least developed countries of the world are in SSA. Rapid urbanization is occurring in many parts of the continent, contributing to overcrowding and poverty. While infections and parasitic diseases are still the leading cause of death in Africa, non-communicable diseases are coming to the forefront. There is a continuing "brain drain" of healthcare workers (physicians and nurses) from Africa to more affluent regions. There are large rural areas of Africa that have no health professionals to serve these populations. There are no nephrologists in many parts of SSA; the numbers vary from 0.5 per million population (pmp) in Kenya to 0.6 pmp in Nigeria, 0.7 pmp in Sudan and 1.1 pmp in South Africa. Chronic kidney disease affects mainly young adults aged 20 - 50 years in SSA and is primarily due to hypertension and glomerular diseases. HIV- related glomerular disease often presents late, with patients requiring dialysis. Diabetes mellitus affects 9.4 million people in Africa. The prevalence of diabetic nephropathy is estimated to be 6 - 16% in SSA. The current dialysis treatment rate is Africa, Nigeria, Mauritius and Ghana, with most of the transplants being living donor transplants, except in South Africa where the majority are from deceased donors. Chronic kidney disease care is especially challenging in SSA, with large numbers of ESRD patients, inadequate facilities, funding and support.

    Chronic kidney disease (CKD) predisposes one to either deficiency or toxic excess of different micronutrients. The knowledge on micronutrients-specifically water-soluble vitamins and trace elements-in CKD is very limited. Consequently, current guidelines and recommendations are mostly based on expert opinions or poor-quality evidence. Abnormalities of micronutrient resources in CKD develop for several reasons. Dietary restrictions and anorexia lead to an insufficient micronutrient intake, while diuretics use and renal replacement therapy lead to their excessive losses. Absorption is unpredictable, and metabolism impaired. Better understanding of the micronutrient needs of CKD patients could have an impact on many complications linked to vitamin and trace element disorders, including high mortality, increased risk of atherosclerosis, inflammation, oxidative stress, anemia, polyneuropathy, encephalopathy, weakness and fragility, muscle cramps, bone disease, depression, or insomnia. Here, we summarize the up-to-date knowledge on micronutrient resources in different stages of CKD, and share our experience with the assessment of micronutrient status.

    Full Text Available Adult patients with chronic kidney disease are at risk of major neurologic and cardiac complications. The purpose of this study is to review the neurological and cardiac complications in children with end-stage renal disease (ESRD. A retrospective review of medical records of children with ESRD at Jordan University Hospital was performed. All neurological and cardiac events were recorded and analyzed. Data of a total of 68 children with ESRD presenting between 2002 and 2013 were reviewed. Neurological complications occurred in 32.4%; seizures were the most common event. Uncontrolled hypertension was the leading cause of neurological events. Cardiac complications occurred in 39.7%, the most common being pericardial effusion. Mortality from neurological complications was 45%. Neurological and cardiac complications occurred in around a third of children with ESRD with a high mortality rate. More effective control of hypertension, anemia, and intensive and gentle dialysis are needed.

    This retrospective study summarizes 11 cases of end-stage renal disease (ESRD) in captive polar bears (Ursus maritimus) from eight zoologic institutions across the United States and Canada. Ten bears were female, one was male, and the mean age at the time of death was 24 yr old. The most common clinical signs were lethargy, inappetence, and polyuria-polydipsia. Biochemical findings included azotemia, anemia, hyperphosphatemia, and isosthenuria. Histologic examination commonly showed glomerulonephropathies and interstitial fibrosis. Based on submissions to a private diagnostic institution over a 16-yr period, ESRD was the most commonly diagnosed cause of death or euthanasia in captive polar bears in the United States, with an estimated prevalence of over 20%. Further research is needed to discern the etiology of this apparently common disease of captive polar bears.

    Background: Short course chemotherapy followed by radiotherapy is a standard treatment for early Hodgkin's disease. There is yet no consensus regarding the appropriate radiotherapy portal following chemotherapy. A good guide to the adjuvant radiotherapy field is the site of relapse in patients treated with chemotherapy alone. Patients and methods: From 1980 to 1996, 61 patients with stage I and II supradiaphragmatic Hodgkin's disease were treated with chemotherapy alone at the Royal Marsden Hospital. We undertook a retrospective review and failure analysis to define the pattern of recurrence. Results: After a median follow-up of 6.5 years, 24 patients had relapsed giving a 5-year relapse rate of 40%. The 5 and 10-year actuarial survival rates were 94 and 89%, respectively with cause-sepecific survival being 94% at 5 and 10 years. Two-thirds of the relapses were nodal and supradiaphragmatic. Twenty patients (83%) relapsed in the initially involved sites of disease and this was the sole site of recurrence in 11 (45%) of patients. In retrospect, it appeared that at least 12 recurrences could have been prevented by involved field radiotherapy. Review of detailed imaging data (available in 9 out of 11 patients with recurrences in initial sites of disease) showed that the relapses were always in the initially involved nodes. Conclusion: After chemotherapy alone in early stage HD most initial recurrences are nodal. Loco-regional recurrences are in the originally involved nodes. Based on limited data it appears that involved nodal RT is equivalent to involved field radiotherapy and may halve the risk of recurrence

  3. Changes in brain oxysterols at different stages of Alzheimer's disease: Their involvement in neuroinflammation

    Full Text Available Alzheimer's disease (AD is a gradually debilitating disease that leads to dementia. The molecular mechanisms underlying AD are still not clear, and at present no reliable biomarkers are available for the early diagnosis. In the last several years, together with oxidative stress and neuroinflammation, altered cholesterol metabolism in the brain has become increasingly implicated in AD progression. A significant body of evidence indicates that oxidized cholesterol, in the form of oxysterols, is one of the main triggers of AD. The oxysterols potentially most closely involved in the pathogenesis of AD are 24-hydroxycholesterol and 27-hydroxycholesterol, respectively deriving from cholesterol oxidation by the enzymes CYP46A1 and CYP27A1. However, the possible involvement of oxysterols resulting from cholesterol autooxidation, including 7-ketocholesterol and 7β-hydroxycholesterol, is now emerging. In a systematic analysis of oxysterols in post-mortem human AD brains, classified by the Braak staging system of neurofibrillary pathology, alongside the two oxysterols of enzymatic origin, a variety of oxysterols deriving from cholesterol autoxidation were identified; these included 7-ketocholesterol, 7α-hydroxycholesterol, 4β-hydroxycholesterol, 5α,6α-epoxycholesterol, and 5β,6β-epoxycholesterol. Their levels were quantified and compared across the disease stages. Some inflammatory mediators, and the proteolytic enzyme matrix metalloprotease-9, were also found to be enhanced in the brains, depending on disease progression. This highlights the pathogenic association between the trends of inflammatory molecules and oxysterol levels during the evolution of AD. Conversely, sirtuin 1, an enzyme that regulates several pathways involved in the anti-inflammatory response, was reduced markedly with the progression of AD, supporting the hypothesis that the loss of sirtuin 1 might play a key role in AD. Taken together, these results strongly support the

    Full Text Available ABSTRACT Background Patients with liver disease often present protein-energy malnutrition. The assessment of food intake is very important in the investigation regarding the "health-disease" process. Objective To assess dietary intake of cirrhotic patients through food record during 3 days, correlating it with the nutritional status of the patient and the stage of the disease. Methods Cirrhotic outpatients from the Santa Casa de Misericórdia Hospital, RS, Brazil, were assessed. Nutritional assessment was performed by anthropometry; non-dominating handgrip strength; adductor pollicis muscle thickness; phase angle by bioelectrical impedance analysis; and Subjective Global Assessment. For analysis of food consumption we used the food records of 3 days using scales for weighing of all foods. Results We evaluated 25 (68% patients, in which there was a prevalence of cirrhosis by hepatitis C virus. The upper arm circumference, handgrip strength and phase angle by bioelectrical impedance analysis diagnosed 56% of malnourished. Phase angle by bioelectrical impedance analysis and upper arm circumference were associated with Child-Pugh score (P<0.05. The average consumption of calories, carbohydrates, proteins and lipids were within the recommended. However, sodium was above the recommendations, 106±57.2 mEq, and was inversely associated with Child-Pugh score (rs=-0.410; P=0.042. Conclusion Food intake did not have a significant difference between the Child-Pugh scores and nutritional status. In addition, food intake did not vary neither according to the stage of the disease, nor to the nutritional assessment, by the phase angle by bioelectrical impedance analysis.

    Improved survival of chronic kidney disease (CKD) patients has led to an increased focus on health-related quality of life (HRQoL) for evaluating treatment effectiveness and assessing health outcomes of these patients. To evaluate HRQoL in patients in different stages of CKD and to explore possible correlating and influencing factors. Cross-sectional design with 200 patients from India in CKD stages 1-5 assessed for HRQoL through 36-item short-form together with biomarkers. Patients were divided into four groups according to their estimated Glomerular Filtration Rate (eGFR); group A with GFR range > 90 ml/min/1.73 m 2 , group B with GFR range 30-59 ml/min/1.73 m 2 , group C with GFR range 15-29 ml/min/1.73 m 2 and group D with GFR stages. A statistically significant decreasing trend in physical composite summary and mental composite summary scores was found in patients from group A to D (Plife. © The Author 2016.

    Gastrointestinal symptoms are early events in Parkinson's disease (PD). The gastrointestinal hormone ghrelin was neuroprotective in the nigrostriatal dopamine system. The objective of this study was to assess ghrelin levels in the early stages of PD. Plasma was collected in the fasting state in 291 PD patients in stages 1-3 and 303 age- and sex-matched healthy controls. Additional samples were taken in the glucose response test to assess nutrition-related ghrelin levels in 20 PD patients and 20 healthy controls. The enzyme-linked immunosorbent assay was used to measure total and active plasma ghrelin levels. We reported that total and active plasma ghrelin levels were decreased in PD, although there was no difference across progressive PD stages. Postprandial ghrelin suppression and preprandial peak responses were both attenuated in PD. Plasma ghrelin levels were decreased in PD; however, this event might be irrelevant to PD progression. Ghrelin responses to meals were also impaired in PD. © 2017 International Parkinson and Movement Disorder Society. © 2017 International Parkinson and Movement Disorder Society.

    2017-03-01

    One of the most difficult decisions for individuals with Alzheimer's disease (AD) is when to stop driving. Because driving is a fundamental activity linked to socialization, independent functioning, and well-being, making the decision to stop driving is not easy. Cognitive decline in older adults can lead to getting lost while driving, difficulty detecting and avoiding hazards, as well as increased errors while driving due to compromised judgment and difficulty in making decisions. The purpose of the current literature review was to synthesize evidence regarding how individuals with early-stage AD, their families, and providers make determinations about driving safety, interventions to increase driving safety, and methods to assist cessation and coping for individuals with early-stage AD. The evidence shows that changes in driving ability start early and progress throughout the trajectory of AD. Some individuals with mild cognitive impairment or early-stage AD may be safe to drive for a period of time. Support groups aimed at helping with the transition have been shown to be helpful for individuals who stop driving. Research and practice must support interventions to help individuals maintain safety while driving, as well as cope with driving cessation. [Res Gerontol Nurs. 2017; 10(2):86-100.].

Papers known to the authors were included, as were scientific statements. Articles were chosen based on the judgment of the authors.Results: Drug-dosing decisions should be based on the method used in the published studies and package labeling that have been determined to be safe, which is most often the Cockcroft–Gault formula unadjusted for body weight. Although Modification of Diet in Renal Disease is more commonly used in practice for staging, the CKD–Epidemiology Collaboration (CKD–EPI equation is the most accurate formula for estimating the CKD staging, especially at higher GFR values. Automated HITs offer a solution to the complexity of determining which equation to use for a given clinical scenario. HITs can educate providers on which formula to use and how to apply the formula in a given clinical situation, ultimately improving appropriate medication and medical management in CKD patients.Conclusion: Appropriate estimation of GFR is key to optimal health outcomes. HITs assist clinicians in both choosing the most appropriate GFR estimation formula and in applying the results of the GFR estimation in practice. Key limitations of the

In order to specify the cholinergic involvement in early stages, we performed a presynaptic imaging study of the cholinergic system using a vesicular Acetylcholine transporter ligand labelled with iodine 123 ( 123 I-IBVM - Iodobenzovesamicol) Materials And Methods Eight patients (5 women and 3 men, 74-89 years, MMS>23) and 8 controls (6 women and 2 men, 72-80 years, MMS>30) have been evaluated using the neuropsychological tests; cerebral SPECT was performed 6 hours after intravenous injection of 218±19 MBq of 123 I - IBVM (30 min, 3 volume, 128x128) and the 3D MRI (T1 weighted images). Acquisition data were processed by filtered retroprojection (Butterworth 5.35) and analysed with SPM software. Each examination was co-registered with the MRI of the patient, normalised in the MNI template and smoothed (10mm). Results The analyse of the group (two sample T-test, p 123 I-IBVM has been detected in the patients group, compared to the control. Conclusions Our results indicate that cholinergic dysfunctions appear very early in the development of Alzheimer's disease and affect the cortical structures involved in the attention process. Some studies are in progress to analyze imaging data with cognitive impairments of each patient. (author)

    With the number of migrants and refugees increasing globally, the nephrology community is increasingly confronted with issues relating to the management of end-stage kidney disease in this population, including medical, logistical, financial, and moral-ethical questions. Beginning with data for the state of affairs regarding refugees in Europe and grounded in moral reasoning theory, this Policy Forum Perspective contends that to improve care for this specific population, there is a need for: (1) clear demarcations of responsibilities across the societal (macro), local (meso), and individual (micro) levels, such that individual providers are aware of available resources and able to provide essential medical care while societies and local communities determine the general approach to dialysis care for refugees; (2) additional data and evidence to facilitate decision making based on facts rather than emotions; and (3) better information and education in a broad sense (cultural sensitivity, legal rights and obligations, and medical knowledge) to address specific needs in this population. Although the nephrology community cannot leverage a change in the geopolitical framework, we are in a position to generate accurate data describing the dimensions of care of refugee or migrant patients with end-stage kidney disease to advocate for a holistic approach to treatment for this unique patient population.

    Full Text Available Fibroblast growth factor 21 (FGF21 is an endocrine factor that regulates glucose and lipid metabolism. Circulating FGF21 predicts cardiovascular events and mortality in type 2 diabetes mellitus, including early-stage chronic kidney disease, but its impact on clinical outcomes in end-stage renal disease (ESRD patients remains unclear. This study enrolled 90 ESRD patients receiving chronic hemodialysis who were categorized into low- and high-FGF21 groups by the median value. We investigated the association between circulating FGF21 levels and the cardiovascular event and mortality during a median follow-up period of 64 months. A Kaplan-Meier analysis showed that the mortality rate was significantly higher in the high-FGF21 group than in the low-FGF21 group (28.3% vs. 9.1%, log-rank, P = 0.034, while the rate of cardiovascular events did not significantly differ between the two groups (30.4% vs. 22.7%, log-rank, P = 0.312. In multivariable Cox models adjusted a high FGF21 level was an independent predictor of all-cause mortality (hazard ratio: 3.98; 95% confidence interval: 1.39-14.27, P = 0.009. Higher circulating FGF21 levels were associated with a high mortality rate, but not cardiovascular events in patient with ESRD, suggesting that circulating FGF21 levels serve as a predictive marker for mortality in these subjects.

    The United States Renal Data System (USRDS) began in 1989 through US Congressional authorization under National Institutes of Health competitive contracting. Its history includes five contract periods, two of 5 years, two of 7.5 years, and the fifth, awarded in February 2014, of 5 years. Over these 25 years, USRDS reporting transitioned from basic incidence and prevalence of end-stage renal disease (ESRD), modalities, and overall survival, as well as focused special studies on dialysis, in the first two contract periods to a comprehensive assessment of aspects of care that affect morbidity and mortality in the second two periods. Beginning in 1999, the Minneapolis Medical Research Foundation investigative team transformed the USRDS into a total care reporting system including disease severity, hospitalizations, pediatric populations, prescription drug use, and chronic kidney disease and the transition to ESRD. Areas of focus included issues related to death rates in the first 4 months of treatment, sudden cardiac death, ischemic and valvular heart disease, congestive heart failure, atrial fibrillation, and infectious complications (particularly related to dialysis catheters) in hemodialysis and peritoneal dialysis patients; the burden of congestive heart failure and infectious complications in pediatric dialysis and transplant populations; and morbidity and access to care. The team documented a plateau and decline in incidence rates, a 28% decline in death rates since 2001, and changes under the 2011 Prospective Payment System with expanded bundled payments for each dialysis treatment. The team reported on Bayesian methods to calculate mortality ratios, which reduce the challenges of traditional methods, and introduced objectives under the Health People 2010 and 2020 national health care goals for kidney disease.

    Few studies have examined the neuropsychological sequelae associated with end-stage pulmonary disease. Neuropsychological data are presented for 47 patients with end-stage chronic obstructive pulmonary disease (COPD) who were being evaluated as potential candidates for lung transplantation. Although patients exhibited a diversity of neurocognitive deficits, their highest frequencies of impairment were found on the Selective Reminding Test (SRT). Specifically, over 50% of the patients completing the SRT exhibited impaired immediate free recall and consistent long-term retrieval deficits, while more than 44% of these individuals displayed deficient long-term retrieval. Deficient SRT long-term storage strategies, cued recall, and delayed recall were exhibited by between 26% and 35% of these patients, while more than 32% of this sample displayed elevated numbers of intrusion errors. Over 31% of the patients completing the Wisconsin Card Sorting Test (WCST) failed to achieve the expected number of categories on this measure, while more than 23% of these individuals demonstrated elevated numbers of perseverative errors and total errors. Clinically notable frequencies of impairment (greater than 20% of the sample) were also found on the Trail Making Test (TMT): Part B and the Wechsler Memory Scale-R (WMS-R) Visual Reproduction II subtest. Minnesota Multiphasic Personality Inventory-2 (MMPI-2) personality assessments indicated that patients were experiencing a diversity of somatic complaints and that they may have been functioning at a reduced level of efficiency. These findings are discussed in light of patients’ end-stage COPD and factors possibly contributing to their neuropsychological test performances. Implications for clinical practice and future research are also included. PMID:14589783

    Alzheimer's disease (AD) and vascular dementia (VD) are serious, irreversible forms of cognitive impairment, which means that an early diagnosis is essential to slow down their progression. One potential neurophysiological biomarker of these diseases is the mismatch negativity (MMN) event-related potentials (ERP) component, which reflects an automatic detection mechanism at the pre-attentive stages of information processing. We evaluated the auditory MMN response in individuals from two patient groups: those in the prodromal stages of AD (P-AD) and those in the prodromal stages of VD (P-VD). Thirty patients (15 P-AD patients and 15 P-VD patients) and 30 age-matched controls were recruited to undergo electrophysiological recordings during the presentation of an auditory deviant-standard-reverse oddball paradigm that was used to elicit genuine MMN responses. We show that over the frontal-central area, the mean amplitude of the MMN was significantly reduced in both the P-AD (p=0.017) and P-VD groups (p=0.013) compared with controls. The MMN peak latency in P-VD patients was significantly shorter than in controls (p=0.027). No MMN response differences between the P-AD and P-VD were found in either the frontal-central or the temporal areas. These results indicate that P-AD and P-VD patients exhibit impaired pre-attentive information processing mechanisms as revealed by the frontal-central area MMN response, which is associated with sensory memory and cognitive deficits.

    Purpose To use resting-state functional magnetic resonance (MR) imaging and graph theory approaches to investigate the brain functional connectome and its potential relation to disease severity in Parkinson disease (PD). Materials and Methods This case-control study was approved by the local research ethics committee, and all participants provided informed consent. There were 153 right-handed patients with PD and 81 healthy control participants recruited who were matched for age, sex, and handedness to undergo a 3-T resting-state functional MR examination. The whole-brain functional connectome was constructed by thresholding the Pearson correlation matrices of 90 brain regions, and the topologic properties were analyzed by using graph theory approaches. Nonparametric permutation tests were used to compare topologic properties, and their relationship to disease severity was assessed. Results The functional connectome in PD showed abnormalities at the global level (ie, decrease in clustering coefficient, global efficiency, and local efficiency, and increase in characteristic path length) and at the nodal level (decreased nodal centralities in the sensorimotor cortex, default mode, and temporal-occipital regions; P left postcentral gyrus and left superior temporal gyrus correlated negatively with Unified Parkinson's Disease Rating Scale III score (P = .038, false discovery rate corrected, r = -0.198; and P = .009, false discovery rate corrected, r = -0.270, respectively) and decreased with increasing Hoehn and Yahr stage in patients with PD. Conclusion The configurations of brain functional connectome in patients with PD were perturbed and correlated with disease severity, notably with those responsible for motor functions. These results provide topologic insights into understanding the neural functional changes in relation to disease severity of PD. © RSNA, 2017 Online supplemental material is available for this article.

    Clinical diagnosis of sporadic Creutzfeldt-Jakob disease (sCJD) is currently based on changes occurring in the late disease stages, which limits early-stage detection. Therefore, we investigated the disease course from the vague symptomatic to the terminal phase. We retrospectively reviewed 36 sCJD patient records, classifying the disease progression into 4 stages based on clinical manifestations: vague symptomatic, possible CJD, probable CJD and chronic vegetative state. We analyzed findings from diffusion-weighted imaging (DWI), electroencephalography (EEG) and cerebrospinal fluid (CSF) 14-3-3 protein testing performed at each stage. In stage 1, the most distinctive feature was DWI hyperintensities in the neocortex, even with negative CSF 14-3-3 protein and EEG results. In stage 2, DWI hyperintensities in the limbic cortex were more remarkable.

    To evaluate the long-term outcomes of treatment of total exudative retinal detachments (ERDs) secondary to Coats disease (stage 3B) and the role of vitrectomy. Retrospective, observational case series. A total of 16 eyes in 16 patients undergoing treatment for total ERDs secondary to Coats disease with at least 5 years of follow-up. We reviewed the records of patients with stage 3B Coats disease. The interventions, including the timing of vitrectomy if used, and clinical course were recorded. The primary outcome measures were visual acuity at the most recent appointment, whether there was progression to neovascular glaucoma (NVG) or phthisis bulbi, and need for enucleation. All patients received ablative treatment (photocoagulation or cryotherapy), with 8 having scleral buckling (SB) and 6 having external drainage of subretinal fluid (XD). Of the 12 patients who had pars plana vitrectomy (PPV), 8 had early PPV (EV) in the first year after presenting, and 4 of 8 in the expectant management group had late PPV (late vitrectomy) at a mean of 4.3 years post-presentation for treatment of significant traction retinal detachment (TRD). The other 4 patients of 8 in the expectant management group did not require vitrectomy. Mean follow-up overall was 9 1/2 years. At the date of last follow-up, 50% had no light perception or light perception vision, which was consistent across the subgroups that underwent EV (4/8), late vitrectomy (2/4), or no PPV (2/4). A total of 4 of 16 patients had progression to NVG or phthisis, 1 of whom required enucleation. In this retrospective series of patients with Stage 3B Coats disease, ablative therapy with a combination of PPV, XD, or SB was effective in preventing progression to NVG or phthisis in the majority of patients, thus preserving the globe. Half of the patients (4/8) in this series who did not undergo PPV in the early vitrectomy group developed late-onset TRD, suggesting a possible role for early prophylactic vitrectomy with possible

    The CRISPR (clustered regularly interspaced short palindromic repeats) system protects archaea and bacteria by eliminating nucleic acid invaders in a crRNA-guided manner. The Sulfolobus islandicus type III-B Cmr-α system targets invading nucleic acid at both RNA and DNA levels and DNA targeting relies on the directional transcription of the protospacer in vivo. To gain further insight into the involved mechanism, we purified a native effector complex of III-B Cmr-α from S. islandicus and characterized it in vitro. Cmr-α cleaved RNAs complementary to crRNA present in the complex and its ssDNA destruction activity was activated by target RNA. The ssDNA cleavage required mismatches between the 5΄-tag of crRNA and the 3΄-flanking region of target RNA. An invader plasmid assay showed that mutation either in the histidine-aspartate acid (HD) domain (a quadruple mutation) or in the GGDD motif of the Cmr-2α protein resulted in attenuation of the DNA interference in vivo. However, double mutation of the HD motif only abolished the DNase activity in vitro. Furthermore, the activated Cmr-α binary complex functioned as a highly active DNase to destroy a large excess DNA substrate, which could provide a powerful means to rapidly degrade replicating viral DNA. © The Author(s) 2016.

    Full Text Available Abstract Background Patients with refractory angina pectoris in end-stage coronary artery disease represent a severe condition with a higher reduction of life-expectancy and quality of life as compared to patients with stable coronary artery disease. It was the purpose of this study to invasively re-evaluate highly symptomatic patients with formerly diagnosed refractory angina pectoris in end-stage coronary artery disease for feasible options of myocardial revascularization. Methods Thirty-four Patients formerly characterized as having end stage coronary artery disease with refractory angina pectoris were retrospectively followed for coronary interventions. Results Of those 34 patients 21 (61.8% were eventually revascularized with percutaneous interventional revascularization (PCI. Due to complex coronary morphology (angulation, chronic total occlusion PCI demanded an above-average amount of time (66 ± 42 minutes, range 25–206 minutes and materials (contrast media 247 ± 209 ml, range 50–750 ml; PCI guiding wires 2.0 ± 1.4, range 1–6 wires. Of PCI patients 7 (33.3% showed a new lesion as a sign of progression of atherosclerosis. Clinical success rate with a reduction to angina class II or lower was 71.4% at 30 days. Surgery was performed in a total of8 (23.5% patients with a clinical success rate of 62.5%. Based on an intention-to-treat 2 patients of originally 8 (25% demonstrated clinical success. Mortality during follow-up (1–18 months was 4.8% in patients who underwent PCI, 25% in patients treated surgically and 25% in those only treated medically. Conclusion The majority of patients with end-stage coronary artery disease can be treated effectively with conventional invasive treatment modalities. Therefore even though it is challenging and demanding PCI should be considered as a first choice before experimental interventions are considered.

    To examine neuropsychiatric and neuropsychological predictors of progression from normal to early clinical stages of Alzheimer disease (AD). From a total sample of 559 older adults from the Massachusetts Alzheimer's Disease Research Center longitudinal cohort, 454 were included in the primary analysis: 283 with clinically normal cognition (CN), 115 with mild cognitive impairment (MCI), and 56 with subjective cognitive concerns (SCC) but no objective impairment, a proposed transitional group between CN and MCI. Two latent cognitive factors (memory-semantic, attention-executive) and two neuropsychiatric factors (affective, psychotic) were derived from the Alzheimer's Disease Centers' Uniform Data Set neuropsychological battery and Neuropsychiatric Inventory brief questionnaire. Factors were analyzed as predictors of time to progression to a worse diagnosis using a Cox proportional hazards regression model with backward elimination. Covariates included baseline diagnosis, gender, age, education, prior depression, antidepressant medication, symptom duration, and interaction terms. Higher/better memory-semantic factor score predicted lower hazard of progression (hazard ratio [HR] = 0.4 for 1 standard deviation [SD] increase, p factor score predicted higher hazard (HR = 1.3 for one SD increase, p = 0.01). No other predictors were significant in adjusted analyses. Using diagnosis as a sole predictor of transition to MCI, the SCC diagnosis carried a fourfold risk of progression compared with CN (HR = 4.1, p factors as significant predictors of more rapid progression from normal to early stages of cognitive decline and highlight the subgroup of cognitively normal elderly with SCC as those with elevated risk of progression to MCI.

    Surgical staging in early-stage uterine cancer is controversial. Preoperative serum CA-125 may be of clinical value in predicting the presence of extra-uterine disease in patients with apparent early-stage endometrial cancer. Between October 6, 2005, and June 17, 2010, 760 patients were enrolled in an international, multicentre, prospective randomized trial (LACE) comparing laparotomy with laparoscopy in the management of endometrial cancer apparently confined to the uterus. Of these, 657 patients with endometrial adenocarcinoma had a preoperative serum CA-125 value recorded. Multiple cross-validation analysis was undertaken to correlate preoperative serum CA-125 with stage of disease (Stage I vs. Stage II+) after surgery. Patients' median preoperative serum CA-125 was 14 U/ml. A cutoff point of 30 U/ml was associated with the smallest misclassification error, and using this cutoff, 98 patients (14.9%) had elevated CA-125 levels. Of those, 36 (36.7%) had evidence of extra-uterine disease. Of the 116 patients (17.7%) with evidence of extra-uterine disease, 31.0% had an elevated CA-125 level. On univariate and multivariable logistic regression analysis, only preoperative CA-125 level, but no other preoperative clinical characteristics were found to be associated with extra-uterine spread of disease. Utilizing a cutoff point of 30 U/ml achieved a sensitivity, specificity, positive predictive value and negative predictive value of 31.0, 88.5, 36.7 and 85.7%, respectively. Elevated CA-125 above 30 U/ml in patients with apparent early-stage disease is a risk factor for the presence of extra-uterine disease and may assist clinicians in the management of patients with clinical Stage I endometrial cancer.

    Understanding causes of disability among elderly individuals is an important public health issue, particularly because of the increasing rate of disabled elderly individuals and the social costs in a rapidly aging society. Accordingly, we aimed to describe the diseases that precede disability and investigate the types of diseases that are related to severe disability among Japanese elderly individuals aged over 75 years. Using claim data from the latter-stage elderly healthcare system and long-term care insurance system, we identified 76,265 elderly individuals over 75 years old who did not qualify as disabled on April 1, 2011. Among them, 3,715 elderly individuals who had been newly qualified as disabled between April 1, 2011 and March 31, 2012 were selected. Disease codes from the medical claim data in the 6 months prior to disability were collected. All descriptions were developed separately for six groups divided by gender and disability level (low, middle, and high). The results of the ordinal logistic analysis including sex and age revealed that men tended to have significantly higher levels of disability (β = 0.417, p disability level groups. In low-level disability groups, cancer in men (12.8%) and arthropathy and fracture in women (11.9% and 13.5%, respectively) were as common as cerebrovascular disorder (12.2% and 9.7%, in men and women, respectively). Stroke was the most common disease for all genders and disability levels. The diseases preceding low-level disability differed by gender. This study demonstrated the need to consider arthropathy and fracture as well as CVD in order to prevent disability.

    Full Text Available Human Immunodeficiency Virus type 1 (HIV-1 known to cause Acquired Immune Deficiency Syndrome (AIDS disease are divided into several subtypes (A, B, C, D, F, G, H, J, K and Circulating Recombinant Form (CRF. Different characteristics of subtype of the virus and its interaction with the host can affect the severity of the disease. This study was to analyze HIV-1 subtypes circulating in HIV/AIDS patients from the East Java region descriptively and to analyze its relationship with clinical stadiums of HIV/AIDS. Information from this research was expected to complement the data of mocular epidemiology of HIV in Indonesia. This study utilited blood plasma from patients who had been tested to be HIV positive who sected treatment to or were reffered to the Intermediate Care Unit of Infectious Disease (UPIPI Dr. Soetomo Hospital Surabaya from various area representing the East Java regions. Plasma was separated from blood samples by centrifugation for use in the the molecular biology examination including RNA extraction, nested PCR using specific primer for HIV gp120 env gene region, DNA purifying, DNA sequencing, and homology and phylogenetic analysis. Based on the nucleotide sequence of the HIV gp120 env gene, it was found that the most dominant subtypes in East Java were in one group of Circulating Recombinant Form (CRF that is CRF01_AE, CRF33_01B and CRF34_01B which was also found in Southeast Asia. In the phylogenetic tree, most of HIV samples (30 samples are in the same branch with CRF01_AE, CRF33_01B and CRF34_01B, except for one sample (HIV40 which is in the same branch with subtype B. HIV subtypes are associated with clinical stadiums (disease severity since samples from different stages of HIV disease have the same subtype.

    Lipids are essential components of cell membranes, contributing to cell fuel, myelin formation, subcellular organelle function, and steroid hormone synthesis. Children with chronic kidney disease (CKD) and end-stage renal disease (ESRD) exhibit various co-morbidities, including dyslipidemia. The prevalence of dyslipidemias in children with CKD and ESRD is high, being present in 39-65% of patients. Elevated lipid levels in children without renal disease are a risk factor for cardiovascular disease (CVD), while the risk for CVD in pediatric CKD/ESRD is unclear. The pathogenesis of dyslipidemia in CKD features various factors, including increased levels of triglycerides, triglyceride-rich lipoproteins, apolipoprotein C3 (ApoC-III), decreased levels of cholesterylester transfer protein and high-density lipoproteins, and aberrations in serum very low-density and intermediate-density lipoproteins. If initial risk assessment indicates that a child with advanced CKD has 2 or more co-morbidities for CVD, first-line treatment should consist of non-pharmacologic management such as therapeutic lifestyle changes and dietary counseling. Pharmacologic treatment of dyslipidemia may reduce the incidence of CVD in children with CKD/ESRD, but randomized trials are lacking. Statins are the only class of lipid-lowering drugs currently approved by the U.S. Food and Drug Administration (FDA) for use in the pediatric population. FDA-approved pediatric labeling for these drugs is based on results from placebo-controlled trial results, showing 30-50% reductions in baseline low-density lipoprotein cholesterol. Although statins are generally well tolerated in adults, a spectrum of adverse events has been reported with their use in both the clinical trial and post-marketing settings.

    We investigated structural hypertrophy and functional hyperfiltration as compensatory adaptations after radical nephrectomy in patients with renal cell carcinoma according to the preoperative chronic kidney disease stage. We retrospectively identified 543 patients who underwent radical nephrectomy for renal cell carcinoma between 1997 and 2012. Patients were classified according to preoperative glomerular filtration rate as no chronic kidney disease--glomerular filtration rate 90 ml/minute/1.73 m(2) or greater (230, 42.4%), chronic kidney disease stage II--glomerular filtration rate 60 to less than 90 ml/minute/1.73 m(2) (227, 41.8%) and chronic kidney disease stage III--glomerular filtration rate 30 to less than 60 ml/minute/1.73 m(2) (86, 15.8%). Computerized tomography performed within 2 months before surgery and 1 year after surgery was used to assess functional renal volume for measuring the degree of hypertrophy of the remnant kidney, and the preoperative and postoperative glomerular filtration rate per unit volume of functional renal volume was used to calculate the degree of hyperfiltration. Among all patients (mean age 56.0 years) mean preoperative glomerular filtration rate, functional renal volume and glomerular filtration rate/functional renal volume were 83.2 ml/minute/1.73 m(2), 340.6 cm(3) and 0.25 ml/minute/1.73 m(2)/cm(3), respectively. The percent reduction in glomerular filtration rate was statistically significant according to chronic kidney disease stage (no chronic kidney disease 31.2% vs stage II 26.5% vs stage III 12.8%, p kidney was not statistically significant (no chronic kidney disease 18.5% vs stage II 17.3% vs stage III 16.5%, p=0.250). The change in glomerular filtration rate/functional renal volume was statistically significant (no chronic kidney disease 18.5% vs stage II 20.1% vs stage III 45.9%, p chronic kidney disease stage (p <0.001). Patients with a lower preoperative glomerular filtration rate had a smaller reduction in

    Full Text Available This study aimed to investigate the topological organization of intrinsic functional brain networks in patients with end-stage renal disease (ESRD.Resting-state functional MRI data were collected from 22 patients with ESRD (16 men, 18-61 years and 29 age- and gender-matched healthy controls (HCs, 19 men, 32-61 years. Whole-brain functional networks were obtained by calculating the interregional correlation of low-frequency fluctuations in spontaneous brain activity among 1,024 parcels that cover the entire cerebrum. Weighted graph-based models were then employed to topologically characterize these networks at different global, modular and nodal levels.Compared to HCs, the patients exhibited significant disruption in parallel information processing over the whole networks (P < 0.05. The disruption was present in all the functional modules (default mode, executive control, sensorimotor and visual networks although decreased functional connectivity was observed only within the default mode network. Regional analysis showed that the disease disproportionately weakened nodal efficiency of the default mode components and tended to preferentially affect central or hub-like regions. Intriguingly, the network abnormalities correlated with biochemical hemoglobin and serum calcium levels in the patients. Finally, the functional changes were substantively unchanged after correcting for gray matter atrophy in the patients.Our findings provide evidence for the disconnection nature of ESRD's brain and therefore have important implications for understanding the neuropathologic substrate of the disease from disrupted network organization perspective.

    Full Text Available To study whole-brain microstructural alterations in patients with end-stage renal disease (ESRD and examine the relationship between brain microstructure and physiological indictors in the disease.Diffusion tensor imaging data were collected from 35 patients with ESRD (28 men, 18-61 years and 40 age- and gender-matched healthy controls (HCs, 32 men, 22-58 years. A voxel-wise analysis was then used to identify microstructural alterations over the whole brain in the ESRD patients compared with the HCs. Multiple biochemical measures of renal metabolin, vascular risk factors, general cognitive ability and dialysis duration were correlated with microstructural integrity for the patients.Compared to the HCs, the ESRD patients exhibited disrupted microstructural integrity in not only white matter (WM but also gray matter (GM regions, as characterized by decreased fractional anisotropy (FA and increased mean diffusivity (MD, axial diffusivity (AD and radial diffusivity (RD. Further correlation analyses revealed that the in MD, AD and RD values showed significantly positive correlations with the blood urea nitrogen in the left superior temporal gyrus and significantly negative correlations with the calcium levels in the left superior frontal gyrus (orbital part in the patients.Our findings suggest that ESRD is associated with widespread diffusion abnormalities in both WM and GM regions in the brain, and microstructural integrity of several GM regions are related to biochemical alterations in the disease.

  10. The epidemiology of end-stage renal disease in Nigeria: the way forward.

    2011-09-01

    The incidence of CKD (Chronic kidney disease) in Nigeria has been shown by various studies to range between 1.6 and 12.4%. We have shown that the burden of renal disease in Nigeria is probably significantly higher than any previous study on end-stage renal disease (ESRD) has documented, as most studies are hospital-based and fail to include the many patients who do not have access to hospital care. The increased prevalence of ESRD among blacks in the United States and South Africa compared with other races also suggests that ESRD may be more prevalent in Africa than in the United States and other developed nations. Common causes of CKD in Nigerian adults are glomerulonephritis and hypertension, while common causes in children are glomerulonephritis and posterior urethral valves. In the United States, diabetes and hypertension are the commonest causes of CKD and glomerulonephritis plays a less important role. Access to renal replacement therapy (RRT) in Nigeria is limited, and mortality rates are very high, ranging between 40 and 50%. Important steps towards improving the situation are the development of prevention programmes and increased funding to ensure increased availability of RRT. To achieve this, health policies concerning CKD must be formulated, and the lack of a renal registry makes it difficult for this to be done. There is need for the development of a functional organizational structure for the reporting of CKD in Nigeria, the Nigerian Renal Registry.

    Some suggest race-specific cutpoints for kidney measures to define and stage chronic kidney disease (CKD), but evidence for race-specific clinical impact is limited. To address this issue, we compared hazard ratios of estimated glomerular filtration rates (eGFR) and albuminuria across races using meta-regression in 1.1 million adults (75% Asians, 21% whites, and 4% blacks) from 45 cohorts. Results came mainly from 25 general population cohorts comprising 0.9 million individuals. The associations of lower eGFR and higher albuminuria with mortality and end-stage renal disease (ESRD) were largely similar across races. For example, in Asians, whites, and blacks, the adjusted hazard ratios (95% confidence interval) for eGFR 45–59 vs. 90–104 ml/min/1.73m2 were 1.3 (1.2–1.3), 1.1 (1.0–1.2) and 1.3 (1.1–1.7) for all-cause mortality, 1.6 (1.5–1.8), 1.4 (1.2–1.7), and 1.4 (0.7–2.9) for cardiovascular mortality, and 27.6 (11.1–68.7), 11.2 (6.0–20.9), and 4.1 (2.2–7.5) for ESRD, respectively. The corresponding hazard ratios for urine albumin-to-creatinine ratio 30–299 mg/g or dipstick 1-positive vs. an albumin-to-creatinine ratio under 10 or dipstick negative were 1.6 (1.4–1.8), 1.7 (1.5–1.9) and 1.8 (1.7–2.1) for all-cause mortality, 1.7 (1.4–2.0), 1.8 (1.5–2.1), and 2.8 (2.2–3.6) for cardiovascular mortality, and 7.4 (2.0–27.6), 4.0 (2.8–5.9), and 5.6 (3.4–9.2) for ESRD, respectively. Thus, the relative mortality or ESRD risks of lower eGFR and higher albuminuria were largely similar among three major races, supporting similar clinical approach to CKD definition and staging, across races.

    The purpose of this paper is to address the potential use of cognitive remediation interventions for children and adolescents with chronic kidney disease (CKD) and end-stage kidney disease (ESKD). The prevalence and risk for neurocognitive dysfunction in children with this condition remains high, but, to date, interventions targeting these challenges have not been attempted either individually or as part of a larger treatment program. This is the next logical step in addressing the neurocognitive dysfunction that can be present in pediatric CKD/ESKD, with the field needing to determine the efficacy of cognitive remediation approaches for this population. To our knowledge, this paper is the first to raise this possibility by identifying candidate treatments addressing the neurocognitive challenges observed in children and adolescents with CKD/ESKD. Initially, we present the rationale for the importance of addressing the cognitive difficulties in this population, including an overview of the literature documenting the neurocognitive deficits associated with pediatric-onset CKD/ESKD. This is followed by a review of five candidate cognitive remediation programs that may be applicable to patients with this condition, and associated factors that could affect such treatment. The paper concludes with suggestions for both clinical and research initiatives that could be implemented to examine cognitive remediation as potential components of a larger treatment program for children and adolescents with CKD/ESKD.

  13. How to Recover from a Brain Disease: Is Addiction a Disease, or Is there a Disease-like Stage in Addiction?

    People struggling with addiction are neither powerless over their addiction, nor are they fully in control. Lewis vigorously objects to the brain disease model of addiction (BDMA), because it makes people lose belief in their self-efficacy, and hence hinders their recovery. Although he acknowledges that there is a compulsive state in addiction, he objects to the claim that this compulsion is carved in stone. Lewis argues that the BDMA underestimates the agency of addicted people, and hence hinder their recovery. Lewis's work offers us a very much to be welcomed neurobiology of recovery. It offers addicted people a hopeful and respectful narrative for their recovery that treats them as agents rather than as damaged brains. However, I argue that overestimating people's agency can also result in people losing belief in their self-efficacy. Lewis's strong focus on the agency of addicted people might not match their experiences of struggle, hence reinforcing their feelings of guilt when they fail to control their use. I propose to replace the notion of addiction as a disease with a notion of a disease-like stage in addiction. I call this stage the duress stage in addiction, in which the addictive behaviour is largely impervious to the agent's values and to available techniques of self-control. However, the agent can overcome this stage by developing new techniques of self-control, by building on their self-concept and belief in self-efficacy, by changing their environments and habits, and by engaging in projects that are meaningful to the agent.

    Full Text Available We describe a case with macular hole (MH associated with Vogt-Koyanagi-Harada (VKH disease. A 71-year-old Japanese woman presented with visual loss and headaches. The best-corrected visual acuity (BCVA was 0.02 in the right eye (RE and 0.1 in the left eye (LE. The patient was diagnosed with VKH based on circumferential choroidal detachments, multiple serous retinal detachments, and optic disc hyperemia. The multiple serous retinal detachments improved with high-dose corticosteroid therapy and gradual tapering. The BCVA was recovered to 1.2/0.7 in the RE/LE. Six weeks after the initial administration of steroid, vitreomacular traction was found by optical coherence tomography in the LE, which progressed to stage 4 MH with the BCVA of 0.2 in the LE. Twenty-three weeks after the initial treatment, vitrectomy was performed with the standard surgical procedures, including inner limiting membrane peeling around the fovea and air tamponade. The MH was closed successfully and the BCVA was 0.4 in the LE 5 weeks after the vitrectomy. This is the first report of a case with MH secondary to the acute uveitic stage of VKH. Successful closure of MH was achieved with the standard surgical intervention for an idiopathic MH. To conclude, at the early stage of VKH, there is a possibility of MH formation due to the rapid progress of vitreous traction following the inflammation, and the surgical procedure could be effective to resolve this secondary disorder.

    Control of hypertension is often a problem in the management of end stage renal disease (ESRD). Multiple modalities of treatment are required to prevent cardiovascular and cerebrovascular mortality and morbidity. These include fluid and salt restriction, multidrug regimes and dialysis. We report a case of young 25 years old patient, admitted with chronic renal failure, complicated by malignant and refractory hypertension, not responding to hemodialysis and antihypertensive agent. During stay in hospital, patient also had intracerebral hemorrhage, fits due to uncontrolled hypertension requiring ventilatory support followed. Renal transplant was considered to be the final therapeutic modality. After gradual recovery, a successful live-related renal transplant was performed. As soon as good graft was established, the blood pressure settled and 4 of the 5 antihypertensives were withdrawn. After 2 weeks, patient was discharged in a stable condition with a total stay of about 2 months. (author)

    Full Text Available Depression is a prevalent burden for patients with end-stage renal disease (ESRD and one that is under-recognized and consequently under-treated. Although several studies have explored the association between depression symptoms, treatment adherence and outcomes in Euro-American patient groups, quantitative and qualitative exploration of these issues in patients from different cultural and ethnic backgrounds has been lacking. This review discusses the methodological issues associated with measuring depression in patients of South Asian origin who have a 3- to 5-fold greater risk of developing ESRD. There is a need to advance research into the development of accurate screening practices for this patient group, with an emphasis on studies utilizing rigorous approaches to evaluating the use of both emic (culture-specific and etic (universal or culture-general screening instruments.

    We have studied the role of the chemokine receptor CCR1 during the effector stage of myelin oligodendrocyte glycoprotein-induced experimental autoimmune encephalomyelitis in DA rats. In situ hybridization histochemistry revealed local production of the CCR1 ligands CCL3 (MIP-1 alpha) and CCL5 (RANTES), as well as large numbers of CCR1 and CCR5 expressing cells within inflammatory brain lesions. A low-molecular weight CCR1 selective antagonist potently abrogated both clinical and histopathological disease signs during a 5-day treatment period, without signs of peripheral immune compromise. Thus, we demonstrate therapeutic targeting of CCR1-dependent leukocyte recruitment to the central nervous system in a multiple sclerosis (MS)-like rat model.

    End-stage renal disease (ESRD) during infancy has been associated with poor short-term neurocognitive outcomes. Limited information exists regarding long-term outcomes. Neurocognitive outcomes for 12 patients diagnosed with ESRD during the first 16 months of life were assessed. Nine patients (mean age: 11 years) were compared to their healthy siblings (mean age: 10 years) on measures of intellectual and executive functioning, memory, and academic achievement using paired-samples t tests. Patients' Full Scale IQ (FSIQ) scores (M = 78, SD = 16.1) were significantly lower than sibling controls (M = 94, SD = 18.9; p executive functioning, memory, and academic achievement. In summary, patients diagnosed with ESRD as infants had intellectual and metacognitive functioning significantly lower than sibling controls. Fewer months on dialysis and younger age at transplant were associated with better outcomes.

    Molecular alterations reflecting pathophysiologic changes thought to occur many years before the clinical onset of Machado-Joseph disease (MJD)/spinocerebellar ataxia type 3 (SCA3), a late-onset polyglutamine disorder, remain unidentified. The absence of molecular biomarkers hampers clinical trials, which lack sensitive measures of disease progression, preventing the identification of events occurring prior to clinical onset. Our aim was to analyse the mtDNA content and the amount of the common deletion (m.8482_13460del4977) in a cohort of 16 preataxic MJD mutation carriers, 85 MJD patients and 101 apparently healthy age-matched controls. Relative expression levels of RPPH1, MT-ND1 and MT-ND4 genes were assessed by quantitative real-time PCR. The mtDNA content was calculated as the difference between the expression levels of a mitochondrial gene (MT-ND1) and a nuclear gene (RPPH1); the amount of mtDNA common deletion was calculated as the difference between expression levels of a deleted (MT-ND4) and an undeleted (MT-ND1) mitochondrial genes. mtDNA content in MJD carriers was similar to that of healthy age-matched controls, whereas the percentage of the common deletion was significantly increased in MJD subjects, and more pronounced in the preclinical stage (p < 0.05). The BCL2/BAX ratio was decreased in preataxic carriers compared to controls, suggesting that the mitochondrial-mediated apoptotic pathway is altered in MJD. Our findings demonstrate for the first time that accumulation of common deletion starts in the preclinical stage. Such early alterations provide support to the current understanding that any therapeutic intervention in MJD should start before the overt clinical phenotype.

    Full Text Available Alzheimer's disease (AD is a devastating disorder of increasing prevalence in modern society. Mild cognitive impairment (MCI is considered a transitional stage between normal aging and AD; however, not all subjects with MCI progress to AD. Prediction of conversion to AD at an early stage would enable an earlier, and potentially more effective, treatment of AD. Electroencephalography (EEG biomarkers would provide a non-invasive and relatively cheap screening tool to predict conversion to AD; however, traditional EEG biomarkers have not been considered accurate enough to be useful in clinical practice. Here, we aim to combine the information from multiple EEG biomarkers into a diagnostic classification index in order to improve the accuracy of predicting conversion from MCI to AD within a two-year period. We followed 86 patients initially diagnosed with MCI for two years during which 25 patients converted to AD. We show that multiple EEG biomarkers mainly related to activity in the beta-frequency range (13–30 Hz can predict conversion from MCI to AD. Importantly, by integrating six EEG biomarkers into a diagnostic index using logistic regression the prediction improved compared with the classification using the individual biomarkers, with a sensitivity of 88% and specificity of 82%, compared with a sensitivity of 64% and specificity of 62% of the best individual biomarker in this index. In order to identify this diagnostic index we developed a data mining approach implemented in the Neurophysiological Biomarker Toolbox (http://www.nbtwiki.net/. We suggest that this approach can be used to identify optimal combinations of biomarkers (integrative biomarkers also in other modalities. Potentially, these integrative biomarkers could be more sensitive to disease progression and response to therapeutic intervention.

    Hyperphosphatemia is common in end-stage renal disease and associates with mortality. Phosphate binders reduce serum phosphorus levels; however, adherence is often poor. This pilot study aims to assess patients' self-motivation to adhere to phosphate binders, its association with phosphorus control, and potential differences by race. Cross sectional design. Subjects were enrolled from one academic medical center dialysis practice from July to November 2012. Self-motivation to adhere to phosphate binders was assessed with the autonomous regulation (AR) scale (range: 1-7) and self-reported medication adherence with the Morisky Medication Adherence Scale. Linear regression models adjusting for age, sex, health literacy, and medication adherence were applied to determine associations with serum phosphorus level, including any evidence of interaction by race. Among 100 participants, mean age was 51 years (±15 years), 53% were male, 72% were non-white, 89% received hemodialysis, and mean serum phosphorus level was 5.7 ± 1.6 mg/dL. More than half (57%) reported the maximum AR score (7). Higher AR scores were noted in those reporting better health overall (P = .001) and those with higher health literacy (P = .01). AR score correlated with better medication adherence (r = 0.22; P = .02), and medication adherence was negatively associated with serum phosphorus (r = -0.40; P motivation was associated with phosphate binder adherence and phosphorus control, and this differed by race. Additional research is needed to determine if personalized, culturally sensitive strategies to understand and overcome motivational barriers may optimize mineral bone health in end-stage renal disease.

    Full Text Available After observing persistently low CD4 counts at initial HIV diagnosis in South Africa, we sought to determine risk factors for late-stage HIV disease presentation among adults.We surveyed adults prior to HIV testing at four outpatient clinics in Durban from August 2010 to November 2011. All HIV-infected adults were offered CD4 testing, and late-stage HIV disease was defined as a CD4 count <100 cells/mm(3. We used multivariate regression models to determine the effects of sex, emotional health, social support, distance from clinic, employment, perceived barriers to receiving healthcare, and foregoing healthcare to use money for food, clothing, or housing ("competing needs to healthcare" on presentation with late-stage HIV disease.Among 3,669 adults screened, 830 were enrolled, newly-diagnosed with HIV and obtained a CD4 result. Among those, 279 (33.6% presented with late-stage HIV disease. In multivariate analyses, participants who lived ≥5 kilometers from the test site [adjusted odds ratio (AOR 2.8, 95% CI 1.7-4.7], reported competing needs to healthcare (AOR 1.7, 95% CI 1.2-2.4, were male (AOR 1.7, 95% CI 1.2-2.3, worked outside the home (AOR 1.5, 95% CI 1.1-2.1, perceived health service delivery barriers (AOR 1.5, 95% CI 1.1-2.1, and/or had poor emotional health (AOR 1.4, 95% CI 1.0-1.9 had higher odds of late-stage HIV disease presentation.Independent risk factors for late-stage HIV disease presentation were from diverse domains, including geographic, economic, demographic, social, and psychosocial. These findings can inform various interventions, such as mobile testing or financial assistance, to reduce the risk of presentation with late-stage HIV disease.

  6. Renal function trajectory is more important than chronic kidney disease stage for managing patients with chronic kidney disease.

    2012-01-01

    Management of patients with chronic kidney disease (CKD) emphasizes a current level of function as calculated from the modification of diet in renal disease glomerulofiltration rate equations (eGFR) and proteinuria for staging of CKD. Change in a patient's eGFR over time (renal function trajectory) is an additional and potentially more important consideration in deciding which patients will progress to the point where they will require renal replacement therapy (RRT). Many patients with CKD 3-5 have stable renal function for years. Proteinuria/albuminuria is a primary determinant of renal trajectory which may be slowed by medications that decrease proteinuria and/or aggressively lower blood pressure. A renal trajectory of >3 ml/min/1.73 m(2)/year may relate to a need for closer renal follow-up and increased morbidity and mortality. Additional CKD population-based studies need to examine the relationship of renal trajectory to: baseline renal function; acute kidney injury episodes; age, race, sex and primary etiologies of renal disease; blood pressure control and therapies; dietary protein intake; blood glucose control in diabetics and the competitive risk of death versus the requirement for renal replacement therapy. In the elderly CKD 4 population with significant comorbidities and slow decline in renal function, the likelihood of death prior to the need for RRT should be considered before placing AV access for dialysis. Prediction models of renal progression must account for the competitive risk of death as well as stable or improved renal function to be clinically useful. Copyright © 2012 S. Karger AG, Basel.

    Full Text Available Abstract Background Chronic kidney disease (CKD and end-stage renal disease (ESRD represent worldwide health problems with an epidemic extent. Therefore, attention must be given to the optimisation of patient care, as gaps in the care of CKD and ESRD patients are well documented. As part of a multidisciplinary patient care strategy, clinical pharmacy services have led to improvements in patient care. The purpose of this study was to summarise the available evidence regarding the role and impact of clinical pharmacy services for these patient populations. Methods A literature search was conducted using the Medline, Embase and International Pharmaceutical Abstracts databases to identify relevant studies on the impact of clinical pharmacists on CKD and ESRD patients, regarding disease-oriented and patient-oriented outcomes, and clinical pharmacist interventions on drug-related problems. Results Among a total of 21 studies, only four (19% were controlled trials. The majority of studies were descriptive (67% and before-after studies (14%. Interventions comprised general clinical pharmacy services with a focus on detecting, resolving and preventing drug-related problems, clinical pharmacy services with a focus on disease management, or clinical pharmacy services with a focus on patient education in order to increase medication knowledge. Anaemia was the most common comorbidity managed by clinical pharmacists, and their involvement led to significant improvement in investigated disease-oriented outcomes, for example, haemoglobin levels. Only four of the studies (including three controlled trials presented data on patient-oriented outcomes, for example, quality of life and length of hospitalisation. Studies investigating the number and type of clinical pharmacist interventions and physician acceptance rates reported a mean acceptance rate of 79%. The most common reported drug-related problems were incorrect dosing, the need for additional

    We have shown previously that skin perfusion is reduced in patients with diabetes mellitus (DM). Patients with diabetes and with chronic kidney disease (CKD) stage 5 were having advanced microangiopathy. In this cross-sectional study, we measured skin blood flow in DM and non-DM patients on dialysis to assess whether any differences exist in skin perfusion in those 2 groups of patients. A total of 25 patients with DM (aged 59.9 +/- 2.2 years) and 24 patients with non-DM CKD stage 5 (44.6 +/- 2.9 years) on hemodialysis (HD) were studied. Ten healthy subjects (37 +/- 4.3 years) were used as a control group. Skin blood flow (SBF) was measured using Vasamedic Model 403B laser Doppler device (Vasamedics Inc., St. Paul, MN) in a standardized way at the plantar and dorsal surface of the finger and toe and at the pretibial surface of the leg at 2 different local skin temperatures of 35 degrees C and 44 degrees C. Laboratory biochemical data were collected at the time of SBF study. The SBF measured at 35 degrees C was lower in the patients with DM on dialysis as compared with healthy subjects and non-DM dialysis patients. The SBF response to the increase in temperature of the probe to 44 degrees C was 70% to 80% lower in DM patients as compared with healthy subjects and non-DM patients. However, non-DM subjects who displayed SBF similar to control subjects at 35 degrees C, had impaired response in SBF at 44 degrees C as well. Patients with lower serum albumin exhibited lower SBF even after adjustment for age. SBF is impaired in patients with stage 5 CKD on HD, particularly in those with DM as a cause of CKD. SBF negatively correlated with age and albumin (nutritional status) in DM and non-DM patients with stage 5 CKD on HD. Measurement of SBF can be useful in the evaluation of vasculopathy in CKD population and can potentially be used for assessment of vascular response during specific clinical intervention.

    Lung transplantation is commonly used for patients with end-stage lung disease. However, there is continuing debate on the optimal operation for patients with chronic obstructive pulmonary disease (COPD) and pulmonary fibrosis. Single-lung transplantation (SLT) provides equivalent short- and medium-term results compared with bilateral lung transplantation (BLT), but long-term survival appears slightly better in BLT recipients (especially in patients with COPD). The number of available organs for lung transplantation also influences the choice of operation. Recent developments suggest that the organ donor shortage is not as severe as previously thought, making BLT a possible alternative for more patients. Among the different complications, re-implantation edema, infection, rejection, and bronchial complications predominate. Chronic rejection, also called obliterative bronchiolitis syndrome, is a later complication which can be observed in about half of the patients. Improvement in graft survival depends greatly in improvement in prevention and management of complications. Despite such complications, graft survival in fibrosis patients is greater than spontaneous survival on the waiting list; idiopathic fibrosis is associated with the highest mortality on the waiting list. Patients should be referred early for the pre-transplantation work-up because individual prognosis is very difficult to predict.

  12. Vitamins and Microelement Bioavailability in Different Stages of Chronic Kidney Disease

    2017-03-01

    Full Text Available Chronic kidney disease (CKD predisposes one to either deficiency or toxic excess of different micronutrients. The knowledge on micronutrients—specifically water-soluble vitamins and trace elements—in CKD is very limited. Consequently, current guidelines and recommendations are mostly based on expert opinions or poor-quality evidence. Abnormalities of micronutrient resources in CKD develop for several reasons. Dietary restrictions and anorexia lead to an insufficient micronutrient intake, while diuretics use and renal replacement therapy lead to their excessive losses. Absorption is unpredictable, and metabolism impaired. Better understanding of the micronutrient needs of CKD patients could have an impact on many complications linked to vitamin and trace element disorders, including high mortality, increased risk of atherosclerosis, inflammation, oxidative stress, anemia, polyneuropathy, encephalopathy, weakness and fragility, muscle cramps, bone disease, depression, or insomnia. Here, we summarize the up-to-date knowledge on micronutrient resources in different stages of CKD, and share our experience with the assessment of micronutrient status.

    Full Text Available Background: End-stage renal disease patients experience increased prevalence of cardiovascular disease. Heart-artery interaction may be shifted, impacting blood pressure lability, and exercise tolerance. The coupling ratio consists of the ratio of indexed arterial elastance (EaI, arterial load to ElvI, a measure of cardiac contractility or stiffness. Our purpose was to explore the relationship between elastances and functional capacity. We hypothesized that arterial stiffness (central pulse wave velocity, PWV and elastances would be correlated to shuttle walk time. Methods: We used applanation tonometry, ultrasonography, and a shuttle walk test to evaluate our hypothesis. Spearman's correlations were used to assess relationships between variables. Block regression was also performed. Results: Forty-two subjects on maintenance hemodialysis participated. Average age=44±5 years, body surface area=2.01 kg/m2. Mean EaI=4.45 and mean ElvI=6.89; the coupling ratio=0.82. Mean aortic pulse pressure=51 mmHg and PWV=9.6 m/s. PWV(r=-0.385 and EaI (r=-0.424 were significantly and inversely related to walking time while stroke volume index (SVI was positively correlated to shuttle walk time (r=0.337, pConclusions: We conclude that, like other clinical populations, both arterial and heart function predict walking ability and represent potential targets for intervention; arterial stiffness and SVI are strongly related to shuttle walk time in patients with ESRD.

    High-sensitivity troponin (hs-TNT), a biomarker of myocardial damage, might be useful for assessing fibrosis in Fabry cardiomyopathy. We performed a prospective analysis of hs-TNT as a biomarker for myocardial changes in Fabry patients and a retrospective longitudinal follow-up study to assess longitudinal hs-TNT changes relative to fibrosis and cardiomyopathy progression. For the prospective analysis, hs-TNT from 75 consecutive patients with genetically confirmed Fabry disease was analyzed relative to typical Fabry-associated echocardiographic findings and total myocardial fibrosis as measured by late gadolinium enhancement (LE) on magnetic resonance imaging. Longitudinal data (3.9±2.0 years), including hs-TNT, LE, and echocardiographic findings from 58 Fabry patients, were retrospectively collected. Hs-TNT level positively correlated with LE (linear correlation coefficient, 0.72; odds ratio, 32.81 [95% CI, 3.56-302.59]; P=0.002); patients with elevated baseline hs-TNT (>14 ng/L) showed significantly increased LE (median: baseline, 1.9 [1.1-3.3] %; follow-up, 3.2 [2.3-4.9] %; PFabry disease and a qualified predictor of cardiomyopathy progression. Thus, hs-TNT could be helpful for staging and follow-up of Fabry patients. © 2016 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley Blackwell.

    Patients with end-stage renal disease (ESRD) and on hemodialysis (HD) are at increased risk for developing rheumatoid arthritis (RA), as a result of defective immunity. Our aim was to examine if ESRD and the length of HD treatment impact the clinical utility of antibodies to cyclic citrullinated peptides (anti-CCP) and rheumatoid factor (RF) as diagnostic tools for RA. We included 94 subjects in our study: 37 healthy volunteers and 57 patients with ESRD who had been undergoing HD for 1-12 years, and without confirmed RA. In order to test our hypothesis, we measured and correlated anti-CCP and RF as laboratory markers of RA. Our study showed that there is no significant difference between values for anti-CCP (p=0.11) and RF (p=0.98) in control subjects as well as in patients undergoing HD, regardless of the length of time that patients had been undergoing HD treatment. Our study indicates that HD does not impair the specificity of anti-CCP and RF for RA in patients where the disease has not yet developed. Future prospective studies may show whether there is any use in determinating RF, and especially anti-CCP, as early predictors of RA in patients with ESRD who are at greater risk of developing this condition.

    Electrolyte and acid-base disturbances are frequent in patients with end-stage liver disease; the underlying physiopathological mechanisms are often complex and represent a diagnostic and therapeutic challenge to the physician. Usually, these disorders do not develop in compensated cirrhotic patients, but with the onset of the classic complications of cirrhosis such as ascites, renal failure, spontaneous bacterial peritonitis and variceal bleeding, multiple electrolyte, and acid-base disturbances emerge. Hyponatremia parallels ascites formation and is a well-known trigger of hepatic encephalopathy; its management in this particular population poses a risky challenge due to the high susceptibility of cirrhotic patients to osmotic demyelination. Hypokalemia is common in the setting of cirrhosis: multiple potassium wasting mechanisms both inherent to the disease and resulting from its management make these patients particularly susceptible to potassium depletion even in the setting of normokalemia. Acid-base disturbances range from classical respiratory alkalosis to high anion gap metabolic acidosis, almost comprising the full acid-base spectrum. Because most electrolyte and acid-base disturbances are managed in terms of their underlying trigger factors, a systematic physiopathological approach to their diagnosis and treatment is required.

    While kidney transplantation (KTx) reverses many disorders associated with end-stage renal disease (ESRD), patients who have received KTx often have chronic kidney disease and bone and mineral disorder (CKD-MBD). However, it is unknown how bone metabolism changes by KTx. Living donor-KTx recipients (n = 34) at Tokyo Women's Medical University were prospectively recruited and the levels of bone-specific alkaline phosphatase (BAP) and serum cross-linked N-telopeptides of Type 1 collagen (NTX) were measured before, 6 and 12 months after transplantation. Before KTx, serum BAP was within the reference range in more than half of patients while NTX was high in most patients. Serum NTX was higher in patients with longer dialysis durations compared to that with shorter durations before KTx. However, there was no difference in serum BAP between these patients. After KTx, BAP increased while NTX decreased along with the decline of PTH. In addition, the numbers of patients who showed high BAP and NTX were comparable after KTx. These results suggest that bone formation is suppressed and uncoupled with bone resorption in patients with ESRD and this uncoupling is restored by KTx. Further studies are necessary to clarify the mechanism of bone uncoupling in patients with ESRD.

  18. End Stage and Chronic Kidney Disease:Associations with Renal Cancer

    2012-04-01

    Full Text Available There is a well known association between end stage renal disease and the development of kidney cancer in the native kidney of patients requiring renal replacement therapy. There is now emerging evidence that lesser degrees of renal insufficiency (chronic kidney disease, CKD are also associated with an increased likelihood of cancer in general and kidney cancer in particular. Nephro pathological changes are commonly observed in the non tumor bearing portions of kidney resected at the time of partial and radical nephrectomy. In addition, patients with renal cancer are more likely to have CKD at the time of diagnosis and treatment than the general population. The exact mechanism by which renal insufficiency transforms normal kidney cells into tumor cells is not known. Possible mechanisms include uremic immune inhibition or increased exposure to circulating toxins not adequately cleared by the kidneys. Surgeons managing kidney tumors must have an increased awareness of their patient’s renal functional status as they plan their resection. Kidney sparing approaches, including partial nephrectomy or active surveillance in older and morbidly ill patients, can prevent CKD or delay the further decline in renal function which is well documented with radical nephrectomy. Despite emerging evidence that partial nephrectomy provides equivalent local tumor control to radical nephrectomy while at the same time preventing CKD, this operation remains under utilized in the United States and abroad. Increased awareness of the bi directional relationship between kidney function and kidney cancer is essential in the contemporary management of kidney cancer.

    The Model for End-Stage Liver Disease (MELD) score is an imperfect prognosticator of waitlist dropout, so transplant centers may apply for exception points to increase a waitlist candidate's priority on the waitlist. Exception applications are categorized as recognized exceptional diagnoses (REDs; eg, hepatocellular carcinoma) and non-REDs (eg, cholangitis). Although prior work has demonstrated regional variation in the use of exceptions, no work has examined the between-center variability. We analyzed all new waitlist candidates from February 27, 2002 to June 3, 2011 to explore variations in the use of non-REDs, for which no strict exception criteria exist. There were 58,641 new waitlist candidates, and 4356 (7.4%) applied for a non-RED exception. The number of applications increased steadily over time, as did the approval rates for such applications: from variation to ensure the appropriate and equitable use of non-RED exceptions. © 2013 American Association for the Study of Liver Diseases.

    Full Text Available Introduction: Hirschsprung's disease(HD is a common congenital disease. In 80% of cases, the recto sigmoid junction is involved. Recently, one-stage transanal endorectal pull-through(TAEPT procedure has been popular, but it could have several complications. In this research, we have studied the complications of this procedure. Methods: During a four year period, 86 infants clinically suspected to have HD were admitted at our center. HD was confirmed by rectal biopsy and all were candidates for TAEPT operation. A Swenson-like procedure was performed and in 30 cases, prophylactic Hegar dilatation was done 2 weeks after operation. Results: Anal stricture was seen in 12 cases(14% of which 10 cases were treated by anal dilation and 2 cases were corrected by surgical management. Entrocolitis was seen in 4 cases(5% who were treated by medical management. In 2 cases, retrocolic abscess was present that was treated by spontaneous drainage via tube drain. There was no anastomotic stricture after starting prophylactic anal bouginage. Conclusion: TAEPT has many advantages and few complications. It seems that one of the most common complications is anastomotic stricture that responds well to prophylactic bouginage. We recommend prophylactic anal bouginage with Hegar probe 2 weeks after operation. A long-term follow-up is needed to evaluate the outcomes of these operations.

    Background/Aims Dialysis and kidney transplantation adversely impact outcomes of total hip or knee arthroplasty (THA, TKA), but complication rates have not been reported for patients with less advanced stages of chronic kidney disease (CKD). Surgeons lack the data necessary to have informed discussions regarding anticipated outcomes of joint replacement for these patients. Methods We retrospectively reviewed electronic health records of 779 adults with stages 1, 2, and 3 CKD not requiring dialysis or transplantation who underwent THA or TKA from 2004–2011, to assess infection, revision, 90-day readmission and mortality rates. Patients with less than 12 months follow-up, open fracture, prior joint surgery, pregnancy, or acute kidney injury were excluded. Chi-square analysis and Cox survival analysis compared these outcomes between the stage 1–2 and stage 3 groups, stratified by joint replaced (THA vs TKA). All models adjusted for age, sex and BMI at surgery. Results No statistically different rates of revision or infection between Stage 3 vs. Stages 1–2 were seen, although there was a trend toward increased infections in Stage 3. THA patients with Stage 3 showed a significantly increased mortality rate compared to Stage 1–2 THA patients (HR 3.40, 95% CI = 1.25–9.23, P = 0.02). Conclusions CKD affects nearly 15% of the U.S. population many of whom undergo joint replacement. End stage kidney disease (patients post-transplant or on hemodialysis) has been consistently associated with increased rates of infection and revision in excess of our observed outcomes, but the overall rate of infection/revision in our study population was only slightly higher than reported rates in the general population (2–7% vs. 1–2%, respectively). CKD should not preclude joint replacement, but these data can help clinicians engage in meaningful informed discussions with patients with mild kidney disease regarding risks for infection, revision and death following joint

    Full Text Available Abstract Background Ovarian cancer is a heterogeneous disease and prognosis for apparently similar cases of ovarian cancer varies. Recurrence of the disease in early stage (FIGO-stages I-II serous ovarian cancer results in survival that is comparable to those with recurrent advanced-stage disease. The aim of this study was to investigate if there are specific genomic aberrations that may explain recurrence and clinical outcome. Methods Fifty-one women with early stage serous ovarian cancer were included in the study. DNA was extracted from formalin fixed samples containing tumor cells from ovarian tumors. Tumor samples from thirty-seven patients were analysed for allele-specific copy numbers using OncoScan single nucleotide polymorphism arrays from Affymetrix and the bioinformatic tool Tumor Aberration Prediction Suite. Genomic gains, losses, and loss-of-heterozygosity that associated with recurrent disease were identified. Results The most significant differences (p  Conclusions The results of our study indicate that presence of two aberrations in TP53 on 17p and LOH on 19q in early stage serous ovarian cancer is associated with recurrent disease. Further studies related to the findings of chromosomes 17 and 19 are needed to elucidate the molecular mechanism behind the recurring genomic aberrations and the poor clinical outcome.

    Full Text Available Anemia is common and is associated with impaired clinical outcomes in diabetic chronic kidney disease (CKD. It may be explained by reduced erythropoietin (EPO synthesis, but recent data suggest that EPO-resistance and diminished iron availability due to inflammation contribute significantly. In this cohort study, we evaluated the impact of hepcidin-25--the key hormone of iron-metabolism--on clinical outcomes in diabetic patients with CKD along with endogenous EPO levels.249 diabetic patients with CKD of any stage, excluding end-stage renal disease (ESRD, were enrolled (2003-2005, if they were not on EPO-stimulating agent and iron therapy. Hepcidin-25 levels were measured by radioimmunoassay. The association of hepcidin-25 at baseline with clinical variables was investigated using linear regression models. All-cause mortality and a composite endpoint of CKD progression (ESRD or doubling of serum creatinine were analyzed by Cox proportional hazards models.Patients (age 67 yrs, 53% male, GFR 51 ml/min, hemoglobin 131 g/L, EPO 13.5 U/L, hepcidin-25 62.0 ng/ml were followed for a median time of 4.2 yrs. Forty-nine patients died (19.7% and forty (16.1% patients reached the composite endpoint. Elevated hepcidin levels were independently associated with higher ferritin-levels, lower EPO-levels and impaired kidney function (all p<0.05. Hepcidin was related to mortality, along with its interaction with EPO, older age, greater proteinuria and elevated CRP (all p<0.05. Hepcidin was also predictive for progression of CKD, aside from baseline GFR, proteinuria, low albumin- and hemoglobin-levels and a history of CVD (all p<0.05.We found hepcidin-25 to be associated with EPO and impaired kidney function in diabetic CKD. Elevated hepcidin-25 and EPO-levels were independent predictors of mortality, while hepcidin-25 was also predictive for progression of CKD. Both hepcidin-25 and EPO may represent important prognostic factors of clinical outcome and have the

    End-stage renal disease (ESRD) is a risk after kidney donation. We sought, in a large cohort of kidney donors, to determine the causes of donor ESRD, the interval from donation to ESRD, the role of the donor/recipient relationship, and the trajectory of the estimated GFR (eGFR) from donation to ESRD. From 1/1/1963 thru 12/31/2015, 4030 individuals underwent living donor nephrectomy at our center, as well as ascertainment of ESRD status. Of these, 39 developed ESRD (mean age ± standard deviation [SD] at ESRD, 62.4 ± 14.1 years; mean interval between donation and ESRD, 27.1 ± 9.8 years). Donors developing ESRD were more likely to be male, as well as smokers, and younger at donation, and to have donated to a first-degree relative. Of donors with a known cause of ESRD (n = 25), 48% was due to diabetes and/or hypertension; only 2 from a disease that would have affected 1 kidney (cancer). Of those 25 with an ascertainable ESRD cause, 4 shared a similar etiology of ESRD with their recipient. Almost universally, thechange of eGFR over time was stable, until new-onset disease (kidney or systemic). Knowledge of factors contributing to ESRD after living kidney donation can improve donor selection and counseling, as well as long-term postdonation care. © 2018 The American Society of Transplantation and the American Society of Transplant Surgeons.

    The prevalence of coronary artery disease (CAD) in end-stage liver disease (ESLD) being evaluated for orthotopic liver transplantation (OLT) is unclear based on variable definition used for CAD. The aim of this study to investigate the prevalence of abnormal stress myocardial perfusion single-photon emission computed tomography (MPS) imaging, as a marker for CAD, among patients with ESLD who were referred for stress MPS imaging as a routine work up before OLT. This was a single-center, retrospective study. We reviewed data on 167 patients who were referred for MPS as a routine work up before OLT over the last 2 years. All patients underwent evaluation for CAD risk factors [age, hypercholesterolemia, diabetes mellitus (DM), hypertension (HTN), and smoking], and stress MPS as per standard protocol. The total number of patients referred for stress MPS was 167. Seven patients (4% of total study population) were excluded from the study due to poor and/or nondiagnostic studies. 147 patients (92%) had normal, but only 13 patients (8%) had abnormal MPS scans. DM and male gender were the most independent risk factors for abnormal MPS with P value of 0.046, and 0.26, respectively. There was no significant association between the abnormal MPS result and HTN, hypercholesterolemia, smoking, age or etiology of the liver disease. Based on our data, the prevalence of abnormal MPS and left ventricular ejection fraction in patients with ESLD was found to be 8%. DM and male gender were the most independent predictor factors for abnormal MPS. True prevalence of CAD and usefulness of MPS in patients with ESLD can only be studied using a very large and randomized prospective study

    Full Text Available Background/Aims: One of the most common causes of anemia of chronic disease (ACD is chronic kidney disease. The main pathomechanism responsible for ACD is subclinical inflammation. The key element involved in iron metabolism is hepcidin, however, studies on new indices of iron status are in progress.The aim of the study was to assess the iron status in patients in early stages of chronic kidney disease, iron correlation with inflammation parameters and novel biomarkers of iron metabolism. Methods: The study included 69 patients. Standard laboratory measurements were used to measure the iron status, complete blood count, fibrinogen, prothrombin index, C-reactive protein concentration (CRP, creatinine, urea, uric acid. Commercially available kits were used to measure high-sensitivity CRP, interleukin 6 (IL-6, hepcidin-25, hemojuvelin, soluble transferrin receptor (sTfR, growth differentiation factor-15 (GDF-15 and zonulin. Results: Absolute iron deficiency was present in 17% of the patients, functional iron deficiency was present in 12% of the patients. Functional iron deficiency was associated with significantly higher serum levels of fibrinogen, ferritin, transferrin saturation, total iron binding capacity, hepcidin and older age relative to patients with absolute iron deficiency. In comparison with patients without iron deficiency, patients with functional iron deficiency were older, with lower prothrombin index, higher fibrinogen, CRP, hsCRP, sTfR, GDF-15, urea and lower eGFR. Hepcidin was predicted by markers of inflammation:ferritin, fibrinogen and IL-6. Conclusion: Inflammation is correlated with iron status. Novel biomarkers of iron metabolism might be useful to distinguish iron deficiency anemia connected with inflammation and absolute iron deficiency.

    Taiwan has the highest incidence of end-stage renal disease (ESRD) in the world. The epidemiologic features of ESRD, however, have not been investigated. In this case-control study, we evaluated the risk of ESRD associated with a number of putative risk factors. We studied 200 patients among whom ESRD had been newly diagnosed between 1 January 2005 and 31 December 2005; 200 controls were selected from among relatives of patients treated in the general surgery unit. Using a structured questionnaire, we collected information related to socioeconomic factors, history of disease, regular blood or urine screening, lifestyle, environmental exposure, consumption of vitamin supplements, and regular drug use at 5 years before disease onset. Our primary multivariate risk models indicated that low socioeconomic status was a strong predictor of ESRD (education: odds ratio [OR], 2.78; 95% confidence interval [CI], 1.49-5.19; income: OR, 2.86, 95% CI, 1.48-5.52), even after adjusting for other risk factors. Other significant predictors for ESRD were a history of hypertension (OR, 3.63-3.90), history of diabetes (OR, 3.85-5.50), and regular intake of folk remedies or over-the-counter Chinese herbs (OR, 10.84-12.51). Regular intake of a multivitamin supplement 5 years before diagnosis was associated with a decreased risk of ESRD (OR, 0.12-0.14). Our findings indicate that low socioeconomic status, history of hypertension, diabetes, and regular use of folk remedies or over-the-counter Chinese herbs were significant risk factors for ESRD, while regular intake of a multivitamin supplement was associated with a decreased risk of ESRD.

    Guideline adherence in chronic kidney disease management is low, despite guideline implementation initiatives. Knowing general practitioners' (GPs') perspectives of management of early-stage chronic kidney disease (CKD) and the applicability of the national interdisciplinary guideline could support strategies to improve quality of care. Qualitative focus group study with 27 GPs in the Netherlands. Three analysts open-coded and comparatively analysed the data. Mind-mapping sessions were performed after data-saturation. Five themes emerged: defining CKD, knowledge and awareness, patient-physician interaction, organisation of CKD care and value of the guideline. A key finding was the abstractness of the CKD concept. The GPs expressed various perspectives about defining CKD and interpreting estimated glomerular filtration rates. Views about clinical relevance influenced the decision-making, although factual knowledge seems lacking. Striving to inform well enough without creating anxiety and to explain suitably for the intellectual ability of the patient caused tension in the patient-physician interaction. Integration with cardiovascular disease-management programmes was mentioned as a way of implementing CKD care in the future. The guideline was perceived as a rough guide rather than a leading document. CKD is perceived as an abstract rather than a clinical concept. Abstractness plays a role in all formulated themes. Management of CKD patients in primary care is complex and is influenced by physician-bound considerations related to individual knowledge and perception of the importance of CKD. Strategies are needed to improve GPs' understanding of the concept of CKD by education, a holistic approach to guidelines, and integration of CKD care into cardiovascular programmes. Not applicable.

    End-stage renal disease (ESRD) presents a significant health burden and is associated with high cardiovascular morbidity and mortality. This is particularly true in African Americans who generally have higher rates of cardiovascular mortality. Outcomes in ESRD are related to extent of cardiovascular disease, but markers for outcome are not clearly established. Global longitudinal strain (GLS) has emerged as an important measure of left ventricular systolic function that is additive to traditional ejection fraction (EF). It can be measured on routine digital echocardiography and is reproducible. This study tested the hypothesis that GLS is associated with mortality in black Americans with ESRD and preserved EF. Forty-eight outpatients undergoing hemodialysis, 59.4 ± 13.3 years, with EF ≥50% were prospectively enrolled. GLS, measured by an offline speckle tracking algorithm, ranged from -8.6% to -22.0% with a mean of -13.4%, substantially below normal (-16% or more negative). The prevalence of left ventricular systolic dysfunction, as determined by GLS, was 89%. Patients were followed for an average of 1.9 years; all-cause mortality was 19% (9 deaths). GLS was significantly associated with mortality (hazard ratio 1.15, 95% confidence interval 1.02 to 1.30, p = 0.02), whereas EF was not. After adjustment for multiple potential confounders (age, gender, race, smoking, hypertension, diabetes, hyperlipidemia, coronary disease, heart failure, and EF), GLS remained strongly associated with mortality (hazard ratio 1.30, 95% confidence interval 1.10 to 1.56, p = 0.002). In conclusion, GLS is an important index in patients with ESRD, which is additive to EF as a marker for mortality in this high-risk group. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Background: Molecular mechanisms of increased cardiovascular mortality in chronic kidney disease (CKD associated with biological age are not well understood. Recent studies support the hypothesis that common factors responsible for this phenomenon are cellular aging and telomere dysfunction. Objectives: The purpose of this study was to investigate the relation between telomerase activity and CKD stages. Methods: The study included 120 patients who were followed-up for CKD stage 2–5D, composed of 30 patients of each stage and 30 healthy volunteers without any known disease who were admitted to our hospital for routine check-ups. Telomerase activity in peripheral blood mononuclear cells (PBMC was measured using the TRAP assay. Results: A significant difference was observed for telomerase activity in PBMC between groups. The detected levels were lowest in the healthy control group (0.15 ± 0.02, and highest in CKD stage 5D patients (0.23 ± 0.04. In CKD patients, telomerase activity in PBMC was positively correlated with the CKD stage, serum creatinine, potassium and parathormone levels, and negatively correlated with estimated glomerular filtration rate (eGFR, body mass index (BMI, platelet count and serum calcium levels. According to the linear regression analysis, independent predictors for high telomerase activity in CKD patients were eGFR and BMI. Conclusion: Telomerase activity in PBMC increases with advancing CKD stage in CKD patients. Increased telomerase activity in PBMC is associated with eGFR and BMI. Resumen: Antecedentes: Los mecanismos moleculares responsables del aumento de la mortalidad cardiovascular en la enfermedad renal crónica (ERC asociada a la edad biológica no se conocen bien.

    Aim: Chemotherapy with Docetaxel and Carboplatin (DC) has shown high response rates in advanced non-small cell lung cancer (NSCLC). Histologic tumor response after chemotherapy or combined chemoradiotherapy is strongly associated with systemic tumor control and potentially cure. Metabolic tumor response assessed by FDG-PET after induction VIP-chemotherapy has been shown to be predictive of outcome in NSCLC. The aim of the present study was to correlate the tumor FDG metabolism as measured by F-18 FDG-PET with morphometric findings after DC induction chemotherapy plus Erythropoietin (10,000 IU Epo s.c. three times a week). Material and Methods: In this prospective multicenter study, 54 patients with NSCLC stage IIIA (9 patients) or IIIB (45 patients) were enrolled and received neoadjuvant treatment with D 100 mg/m 2 d1 and C AUC 7.5 d2 q21 days for 4 cycles prior to surgery. Postoperatively, all patients received adjuvant radiotherapy. WB-PET-studies (ECAT Exact 47) were obtained p.i. of 400 MBq F-18 FDG. Standardized uptake values (SUV), metabolic tumor diameter (MTD) and metabolic tumor index (MTI SUV x MTD) were assessed. Image fusion of PET and CT data was applied on a HERMES computer. Results: Of 54 enrolled patients, 46 were evaluable for response by CT. 30/46 patients (65%) achieved complete remission (CR, 1 patient) or partial remission (PR 29 patients.). Of the 46 patients, 37 patients completed neoadjuvant chemotherapy (Chx) and were studied before and after Chx by FDG-PET. 14 (30% of the 46 evaluable patients) had SUV < 2.5, corresponding to metabolic complete remission (mCR), 23 had PR or stable disease (non-mCR); in 9 patients, PET was not performed because of progressive disease demonstrated by CT. The R0-resection rate was 56% (27/48 evaluable patients). Of the 14 patients with metabolic CR, 9 were evaluated by morphometry. All had regression grades III (no vital tumor cells) or grade IIB (< 10% vital tumor cells and induced apoptosis). With a median

    Background: Coronary heart disease patients and end-stage renal disease patients have been documented to have an increased amount of coronary artery calcifications (CAC). Purpose: To evaluate the distribution of CAC and its influence on interscan variability of measurement in end-stage renal disease and coronary heart disease patients, proven to have calcifications. Material and Methods: 69 patients having CAC, including 34 with coronary heart disease and 35 with end-stage renal disease, were scanned twice with multidetector-row computed tomography (MDCT). Amount of CAC was determined as the number of calcified lesions (CN), total calcium score (CS), calcium volume (CV), and calcium mass (CM). Distribution of CAC was evaluated on a per-patient basis as the median CS and CM of a single lesion. Density of the calcifications was calculated as the patient's CM divided by CV. Results: The overall median CS was 457.2, and the median CM was 75.6 mg. There were no significant differences in the number of calcified lesions, CS, or CM between the two groups. Both CS and CM of a single lesion, as well as the mean calcium density were lower in renal disease patients (P<0.05) than in coronary heart disease subjects. The relative interscan variability of coronary calcium measurement was higher in the renal disease group (P<0.05). There was a negative correlation between the calcium concentration and the relative interscan variability. Conclusion: The results indicate that the coronary calcium distribution influences the measurement interscan reproducibility, and the distribution may differ between end-stage renal disease patients and coronary heart disease patients, reflecting the dissimilar nature of coronary calcifications in those groups.

    Vacuum-assisted closure (VAC) therapy has been shown to be effective at reducing bacterial counts in wounds until definitive bony coverage. However, there is continued debate over timing and type of definitive wound coverage even with VAC therapy application. From 2004 to 2009, 32 patients with Gustilo type IIIB open tibia fractures were initially treated with VAC therapy were included. The number of debridements, length of treatment with VAC dressing, definitive wound coverage management, and length of hospital stay, flap-related complications, and time to radiographic fracture healing were recorded. The mean Injury Severity Score was 17.3 ± 2.0. All wounds closed after being treated with the primary VAC closure. The mean interval between the initial injury and definitive intervention was 10.9 days ± 0.3 days. Twenty of 27 patients (74%) underwent rotational muscle flaps; four received free muscle flaps and three only with split-thickness skin grafts for definitive wound coverage. Nine of 32 patients (28%) underwent below knee amputation, five without flap coverage after several VAC sessions and four after definitive flap coverage. The average time to union was 10.0 months ± 2.0 months. Eight patients developed nonunion and 11 patients developed infections. The average follow-up time is 2.4 years ± 0.2 years. Patients were divided into two groups for analysis according to the interval time. The rate of infection was significantly increased in patients who had an interval of more than 7 days from the time of injury to flap coverage. The VAC therapy may help to reduce the flap size and need for a flap transfer for type IIIB open tibial fractures. However, prolonged periods of VAC usage, greater than 7 days, should be avoided to reduce higher infection and amputation risks.

    Full Text Available Non-adaptive remodeling of cardiovascular system and progressive kidney damage at chronic kidney disease (CKD is associated with the development of endothelial dysfunction (ED and apoptosis. The aim of this research was to study the changes of indicators of apoptosis and ED in patients with CKD 1 stage throughout 12 months. Complex biochemical, immunoferment and tool methods were applied at patient examinations. Arterial pressure of all observed patients was resolved on target values in 12 months. However, the indicators of endothelium-dependent vasodilation (EDV increased in 55 patients (1st group, and the peak of circulating blood volume in skin microvessels in 22 patients (2nd group wasn't changed: 134±4 % и 136±4 %, p>0.1. The level of the annexin A5 reduced from 3.5±0.47 to 1.27±0.31 ng/ml (p0.1 in 2nd group. Diurnal excretion of sodium chloride decreased from 6.8±0.57 g/d to 2.8±0.39 g/d (p<0.05 in patients of 1st group. Dynamics of these indicators was not marked in patients of 2nd group: accordingly from 7.39±0.63 g/d to 7.01±0.65 g/d. Diurnal excretion of sodium chloride reflected the salt intake in patients with CKD 1 stage is associated with disturbance of endothelial-dependent vasodilation and apoptosis.

    Full Text Available Abstract Background Alzheimer's Disease (AD affects a growing proportion of the population each year. Novel therapies on the horizon may slow the progress of AD symptoms and avoid cases altogether. Initiating treatment for the underlying pathology of AD would ideally be based on biomarker screening tools identifying pre-symptomatic individuals. Early-stage modeling provides estimates of potential outcomes and informs policy development. Methods A time-to-event (TTE simulation provided estimates of screening asymptomatic patients in the general population age ≥55 and treatment impact on the number of patients reaching AD. Patients were followed from AD screen until all-cause death. Baseline sensitivity and specificity were 0.87 and 0.78, with treatment on positive screen. Treatment slowed progression by 50%. Events were scheduled using literature-based age-dependent incidences of AD and death. Results The base case results indicated increased AD free years (AD-FYs through delays in onset and a reduction of 20 AD cases per 1000 screened individuals. Patients completely avoiding AD accounted for 61% of the incremental AD-FYs gained. Total years of treatment per 1000 screened patients was 2,611. The number-needed-to-screen was 51 and the number-needed-to-treat was 12 to avoid one case of AD. One-way sensitivity analysis indicated that duration of screening sensitivity and rescreen interval impact AD-FYs the most. A two-way sensitivity analysis found that for a test with an extended duration of sensitivity (15 years the number of AD cases avoided was 6,000-7,000 cases for a test with higher sensitivity and specificity (0.90,0.90. Conclusions This study yielded valuable parameter range estimates at an early stage in the study of screening for AD. Analysis identified duration of screening sensitivity as a key variable that may be unavailable from clinical trials.

    Full Text Available The aim. To assess the influence of liver fibrosis stage on the clinical course of periodontal diseases in patients with chronic hepatitis C. Material and Methods. 122 patients with chronic hepatitis C, treated at the 7th department ofLvivRegionalInfectiousDiseasesHospital during 2013 – 2015 were included into dental investigation. The periodontal disease was diagnosed in accordance with the classification of M. F. Danilevsky (1994. The clinical condition of periodontium was assessed by the papillary marginal alveolar index (PMA in the modification ofParma, by the periodontal index – PI (AL Russel, 1956, by the Muhlemann and Son index – the degree of bleeding in the region of the gingival papilla (PBI. The stage of liver fibrosis was determined according to the medical history. The significance of the difference between two or more relative indicators was calculated using the Fisher test with the Metropolis algorithm. The correlation dependence between the clinical condition of periodontal tissues and the stage of liver fibrosis in patients with viral hepatitis C was studied using the Spearman rank correlation coefficient. Results. The highest percentage of patients with stage of liver fibrosis F0 (70.00 ± 15.28 % was registered in patients with healthy periodont, the lowest - in patients with generalized periodontitis of the third stage (7.89 ± 4.37 %. The highest frequency of patients with the stage of liver fibrosis F3 (73.68 ± 7.14 % was also observed in persons suffering from generalized periodontitis stage III (73.68 ± 7.14 %. Conclusions. The distribution of periodontal lesion severity statistically significant (p < 0.001 depended on the stage of liver fibrosis in patients with chronic hepatitis C. Direct (R = 0.70; p < 0.001 strong correlation between the clinical state of periodontal tissues and the stage of liver fibrosis in patients with chronic hepatitis C (using the Spearman rank correlation coefficient has been determined

    Background Little is known about muscle mass loss in early stage chronic kidney disease (CKD). We used 24-hour urinary creatinine excretion rate to assess determinants of muscle mass and its evolution with kidney function decline. We also described the range of urinary creatinine concentration in this population. Methods We included 1072 men and 537 women with non-dialysis CKD stages 1 to 5, all of them with repeated measurements of glomerular filtration rate (mGFR) by 51Cr-EDTA renal clearance and several nutritional markers. In those with stage 1 to 4 at baseline, we used a mixed model to study factors associated with urinary creatinine excretion rate and its change over time. Results Baseline mean urinary creatinine excretion decreased from 15.3±3.1 to 12.1±3.3 mmol/24 h (0.20±0.03 to 0.15±0.04 mmol/kg/24 h) in men, with mGFR falling from ≥60 to creatinine excretion at baseline. Mean annual decline in mGFR was 1.53±0.12 mL/min/1.73 m2 per year and that of urinary creatinine excretion rate, 0.28±0.02 mmol/24 h per year. Patients with fast annual decline in mGFR of 5 mL/min/1.73 m2 had a decrease in urinary creatinine excretion more than twice as big as in those with stable mGFR, independent of changes in urinary urea as well as of other determinants of low muscle mass. Conclusions Decrease in 24-hour urinary creatinine excretion rate may appear early in CKD patients, and is greater the more mGFR declines independent of lowering protein intake assessed by 24-hour urinary urea. Normalizing urine analytes for creatininuria may overestimate their concentration in patients with reduced kidney function and low muscle mass. PMID:25401694

    Full Text Available The management of human African trypanosomiasis (HAT is constrained by lack of simple-to-use diagnostic, staging, and treatment tools. The search for novel biomarkers is, therefore, essential in the fight against HAT. The current study aimed at investigating the potential of IL-6 as an adjunct parameter for HAT stage determination in vervet monkey model. Four adult vervet monkeys (Chlorocebus aethiops were experimentally infected with Trypanosoma brucei rhodesiense and treated subcuratively at 28 days after infection (dpi to induce late stage disease. Three noninfected monkeys formed the control group. Cerebrospinal fluid (CSF and blood samples were obtained at weekly intervals and assessed for various biological parameters. A typical HAT-like infection was observed. The late stage was characterized by significant (P<0.05 elevation of CSF IL-6, white blood cell count, and total protein starting 35 dpi with peak levels of these parameters coinciding with relapse parasitaemia. Brain immunohistochemical staining revealed an increase in brain glial fibrillary acidic protein expression indicative of reactive astrogliosis in infected animals which were euthanized in late-stage disease. The elevation of IL-6 in CSF which accompanied other HAT biomarkers indicates onset of parasite neuroinvasion and show potential for use as an adjunct late-stage disease biomarker in the Rhodesian sleeping sickness.

    To test the hypothesis that bone marrow oedema (BME) observed on MRI in patients with avascular necrosis (AVN) of the femoral head represents an indicator of subchondral fracture. Thirty-seven symptomatic hips of 27 consecutive patients (53% women, mean age 49.2) with AVN of the femoral head and associated BME on magnetic resonance (MR) imaging were included. MR findings were correlated with computed tomography (CT) of the hip and confirmed by histopathological examination of the resected femoral head. Imaging studies were analysed by two radiologists with use of the ARCO classification. On MR imaging a fracture line could be identified in 19/37 (51%) cases, which were classified as ARCO stage 3 (n = 15) and stage 4 (n = 4). The remaining 18/37 (49%) cases were classified as ARCO stage 2. However, in all 37/37 (100%) cases a subchondral fracture was identified on CT, indicating ARCO stage 3/4 disease. The extent of subchondral fractures and the femoral head collapse was graded higher on CT as compared to MRI (P AVN, BME of the femoral head represents a secondary sign of subchondral fracture and thus indicates ARCO stage 3 disease. BME on MRI in AVN of femoral head indicates a subchondral fracture. BME in AVN of the femoral head represents ARCO stage 3/4 disease. CT identifies subchondral fractures and femoral head collapse better than MR imaging. This knowledge helps to avoid understaging and to trigger adequate treatment.

    Purpose: To examine the costs and benefits of an established practice of routine follow-up in a cohort of patients treated with radiation therapy for early stage Hodgkin's disease. Materials and Methods: We retrospectively examined patterns of follow-up and methods of relapse detection among 709 patients with Ann Arbor Stage I-II Hodgkin's disease treated with sub-total lymphoid irradiation (STLI) or total lymphoid irradiation (TLI) between 1969-1994. We determined the probability of relapse detection for each of 7 routine follow up procedures, compared their relative costs, and determined the impact of each procedure on the likelihood of overall survival following salvage therapy. Results: Relapse has occurred in 157 patients (22%) at a median 1.9 years (range 0-13 years) following treatment. 133 relapses (85%) occurred during the first 5 years of follow. Detailed information concerning the method of relapse detection was available on 107 patients. These 107 patients form the basis of this analysis. Relapse was identified by history (Hx) alone in 55% of patients, physical exam (PE) in 14%, chest x-ray (CXR) in 23% and abdominal x-ray (KUB) in 7%. Only one relapse (1%) was identified by a routine laboratory study - erythrocyte sedimentation rate (ESR). The rate of relapse detection was highest for a combination of history and physical exam (78/10,000 exams) followed by CXR (26/10,000 exams), KUB (10/10,000 exams) and ESR (1/10,000 tests). Complete blood count (CBC) and serum chemistries were never the primary factor in detecting HD relapse. Radiographs accounted for greater than 60% of charges while laboratory studies and physician charges accounted for approximately 20% each. The projected charges (1994 dollars) of relapse detection by routine follow up Hx and PE was [dollar]10,600 compared with [dollar]68,200 for CXR, [dollar]141,800 for KUB and [dollar]156,400 for ESR. 10 year actuarial survival following salvage therapy was 65% overall, 65% for patients in whom

    Dietary modification is an important component of the management of end stage kidney disease (ESKD). The diet for ESKD involves modifying energy and protein intake, and altering sodium, phosphate, potassium and fluid intake. There have been no comprehensive reviews to date on this topic. The aims of this integrative review were to (i) describe the methods used to measure dietary adherence (ii) determine the rate of dietary adherence and (iii) describe factors associated with dietary adherence in ESKD. The Web of Science and Scopus databases were searched using the search terms 'adherence' and 'end stage kidney disease'. Of the 787 potentially eligible papers retrieved, 60 papers of 24,743 patients were included in this review. Of these papers, 44 reported the rate of dietary adherence and 44 papers described factors associated with adherence. Most of the evidence regarding dietary adherence is derived from studies of hemodialysis patients (72% of patients). The most common method of measuring dietary adherence in ESKD was subjective techniques (e.g. food diaries or adherence questionnaires). This was followed by indirect methods (e.g. serum potassium, phosphate or interdialytic weight gain). The weighted mean adherence rate to ESKD dietary recommendations was 31.5% and 68.5% for fluid recommendations. Adherence to protein, sodium, phosphate, and potassium recommendations were highly variable due to differences in measurement methods used, and were often derived from a limited evidence base. Socioeconomic status, age, social support and self-efficacy were associated with dietary adherence. However, factors such as taste, the impact of the diet on social eating occasions; and dietetic staffing also appear to play a role in dietary adherence. Dietary adherence rates in people with ESKD are suboptimal. Further research is required on dietary adherence in patients with ESKD from different social, educational, economic and ethnic groups. This research may identify other

    With progression of chronic kidney disease (CKD), disorders of mineral metabolism appear. The classic sequence of events begins with a deficit of calcitriol synthesis and retention of phosphorus. As a result of this, serum calcium decreases and parathyroid hormone (PTH) is stimulated, producing in the bone the high turnover (HT) bone disease known as osteitis fibrosa while on the other extreme we find the forms of low turnover (LT) bone disease. Described later and initially associated with aluminum intoxication, these diseases are now seen primarily in older and/or diabetic patients, who in a uremic setting have relatively low levels of PTH to maintain normal bone turnover. Osteomalacia is also included in this group, which after the disappearance of aluminum intoxication is rarely observed. LT forms of hyperparathyroidism facilitate the exit of calcium (Ca) and phosphorus (P) from bone, whereas the adynamic bone limits the incorporation of Ca and P into bone tissue. Therefore, both forms facilitate the availability of Ca and P, which ends up being deposited in soft tissues such as arteries. The link between bone disease and vascular calcifications in CKD is now a well-established phenomenon. 2. Diagnostic strategies Calcium, Phosphorus They have little capacity to predict underlying bone disease, but their regular measurement is decisive for therapeutic management of the patient, especially in the dose titration stages of intestinal phosphorus binders, vitamin D analogs or calcimimetics. Ideally, Ca++ should be used, but total Ca is routinely used. It is recommended to adjust albumin levels in the event of hypoalbuminemia (for each g/dL of decrease in albumin, total serum Ca decreases 0.9 mg/dL). The following formula facilitates rapid calculation of corrected total calcium: Corrected total Ca (mg/dL) = total Ca (mg/dL) + 0.8 [4-albumina (g/dL)]. Parathyroid hormone "Intact" PTH is the biochemical parameter that best correlates with bone histology (levels

    Bacterial communities are called another "organ" for aquatic animals and their important influence on the health of host has drawn increasing attention. Thus, it is important to study the relationships between aquatic animals and bacterial communities. Here, bacterial communities associated with Litopenaeus vannamei larvae at different healthy statuses (diseased and healthy) and growth stages (i.e., zoea, mysis, and early postlarvae periods) were examined using 454-pyrosequencing of the 16S rRNA gene. Bacterial communities with significant difference were observed between healthy and diseased rearing water, and several bacterial groups, such as genera Nautella and Kordiimonas could also distinguish healthy and diseased shrimp. Rhodobacteraceae was widely distributed in rearing water at all growth stages but there were several stage-specific groups, indicating that bacterial members in rearing water assembled into distinct communities throughout the larval development. However, Gammaproteobacteria , mainly family Enterobacteriaceae , was the most abundant group (accounting for more than 85%) in shrimp larvae at all growth stages. This study compared bacterial communities associated with healthy and diseased L . vannamei larvae and rearing water, and identified several health- and growth stage-specific bacterial groups, which might be provided as indicators for monitoring the healthy status of shrimp larvae in hatchery.

    Twenty-three patients with clinical Stage IA to IIIB Hodgkin disease underwent extended-field radiotherapy, including the intact spleen. In 17 of those patients, there was little evidence of renal dysfunction resulting from partial irradiation of the left kidney, which is inherent in such treatment. While isotopic images revealed an anatomic defect in the upper pole of the left kidney in one-third of the patients, dynamic studies showed that this anatomic alteration was not accompanied by any demonstrable dysfunction. Consistently normal serum BUN and creatinine levels in all patients tended to affirm that conclusion

    Chagas' disease, or American trypanosomosiasis, has been the most relevant illness produced by protozoa in Latin America. Synthetic medicinal chemistry efforts have provided an extensive number of chemodiverse hits at the "active-to-hit" stage. However, only a more limited number of these have been studied in vivo in models of Chagas' disease. Herein, we survey some of the cantidates able to surpass the "hit-to-lead" stage discussing their limitations or merit to enter in clinical trials in the short term.

    Full Text Available Polyuria after kidney transplantation causes graft dysfunction and increased thrombotic risk. We present a case of a polyuric adult with Dent’s disease who underwent staged bilateral native nephrectomies, the first operation before transplant and the second four months after transplant. This led to improved allograft function maintained during four years of follow-up. The retroperitoneal laparoscopic approach was well tolerated and allowed continuation of peritoneal dialysis before transplantation. A staged approach helps regulate fluid balance perioperatively and may be tailored to individual need according to posttransplant urine output. This novel approach should be considered for polyuric patients with tubular dysfunction including Dent’s disease.

    This study aims to characterise the timing of referral to a paediatric nephrology unit of children who develop end-stage kidney disease (ESKD). This study also aims to determine whether late referral (LR) influences outcomes and to explore factors that may lead to LR. A retrospective case review of all incident patients with ESKD who received renal replacement therapy (RRT) at a single paediatric centre. Time between referral to a paediatric nephrologist and commencement of RRT, demographic and clinical data were collated. Estimated glomerular filtration rate (eGFR) at referral was calculated using height and creatinine. LR was defined as having an eGFR ≤ 30 mL/min/1.73 m(2) when first seen by a paediatric nephrologist. RRT was initiated for 74 patients Children referred before age 1 year (41%) had a more prolonged course before ESKD. Median (interquartile range) eGFR at referral of children > 1 year was 27.2 (9.0-52.0) mL/min/1.73 m(2) . Twenty-two (55%) of these children were referred late (LR) with an eGFR ≤ 30 mL/min/1.73 m(2) . LR patients were more likely to have glomerulonephritis or haemolytic uraemic syndrome and to live in a remote or outer regional area. LR patients had higher urea, lower haemoglobin and were more likely to receive haemodialysis via a vascular catheter. A significant proportion of children who develop ESKD are referred late to nephrology units with potentially preventable complications. Aetiology of renal disease and geographic isolation contribute to LR. © 2011 The Authors.

    End-stage kidney disease is a leading cause of morbidity and mortality worldwide. Prevalence of the disease and worldwide use of renal replacement therapy (RRT) are expected to rise sharply in the next decade. We aimed to quantify estimates of this burden. We systematically searched Medline for observational studies and renal registries, and contacted national experts to obtain RRT prevalence data. We used Poisson regression to estimate the prevalence of RRT for countries without reported data. We estimated the gap between needed and actual RRT, and projected needs to 2030. In 2010, 2·618 million people received RRT worldwide. We estimated the number of patients needing RRT to be between 4·902 million (95% CI 4·438-5·431 million) in our conservative model and 9·701 million (8·544-11·021 million) in our high-estimate model, suggesting that at least 2·284 million people might have died prematurely because RRT could not be accessed. We noted the largest treatment gaps in low-income countries, particularly Asia (1·907 million people needing but not receiving RRT; conservative model) and Africa (432,000 people; conservative model). Worldwide use of RRT is projected to more than double to 5·439 million (3·899-7·640 million) people by 2030, with the most growth in Asia (0·968 million to a projected 2·162 million [1·571-3·014 million]). The large number of people receiving RRT and the substantial number without access to it show the need to both develop low-cost treatments and implement effective population-based prevention strategies.

    Dysphagia in patients with Parkinson's disease (PD) significantly reduces quality of life and predicted lifetime. Current screening procedures are insufficiently evaluated. We aimed to develop and validate a patient-reported outcome questionnaire for early diagnosis of dysphagia in patients with PD. The two-phased project comprised the questionnaire, diagnostic scales construction (N = 105), and a validation study (N = 82). Data for the project were gathered from PD patients at a German Movement Disorder Center. For validation purposes, a clinical evaluation focusing on swallowing tests, tests of sensory reflexes, and fiberoptic endoscopic evaluation of swallowing (FEES) was performed that yielded a criteria sum score against which the results of the questionnaire were compared. Specificity and sensitivity were evaluated for the detection of noticeable dysphagia and for the risk of aspiration. The Munich Dysphagia Test - Parkinson's disease (MDT-PD) consists of 26 items that show high internal consistency (α = 0.91). For the validation study, 82 patients, aged 70.9 ± 8.7 (mean ± SD), with a median Hoehn & Yahr stage of 3, were assessed. 73% of patients had dysphagia with noticeable oropharyngeal symptoms (44%) or with penetration/aspiration (29%). The criteria sum score correlated positively with the screening result (r = 0.70, p dysphagia vs. risk of aspiration (noticeable dysphagia) with a sensitivity of 90% (82%) and a specificity of 86% (71%), and yielded similar results in cross-validation, respectively. MDT-PD is a valid screening tool for early diagnosis of swallowing problems and aspiration risk, as well as initial graduation of dysphagia severity in PD patients. Copyright © 2014 Elsevier Ltd.

    The epidemiology of new patients presenting to Sultanah Aminah Hospital Johor Bahru (HSAJB) with end-stage renal disease (ESRD) in 2003 and 2004 was analysed. Patients with ESRD were prospectively registered in the renal replacement therapy (RRT) database in the nephrology unit. The incidence of ESRD and the RRT provision rate in the district of Johor Bahru were calculated according to gender and race. There were 306 new patients in 2003 and 299 in 2004. Diabetic nephropathy contributed 56.8% new patients in 2003 and 57.9% in 2004. The mean age was 50.8 + 15.1 years in 2003 and 51.3 + 14.2 years in 2004. Males accounted for 53.3% in 2003 and 47.8% in 2004. Haemodialysis was the commonest form of RRT (60.5% in 2003, 69.9% in 2004), followed by continuous ambulatory peritoneal dialysis (30.1% in 2003, 19.4% in 2004) and renal transplantation (5.5% in 2003, 2.3% in 2004). Ninety-one percent of patients in 2003 and 90% in 2004 were alive at the end of the year they presented. The incidence of ESRD in the district of Johor Bahru was estimated as 136 per million population (p.m.p.) in 2003 and 151 p.m.p. in 2004. In the two year period the incidence of ESRD was higher among females (154 p.m.p.) than males (134 p.m.p.). Malays (194 p.m.p.) had higher ESRD incidence compared to Chinese (126 p.m.p.) and Indians (134 p.m.p.). RRT provision in Johor Bahru (92.7%) did not differ significantly with gender or race. The increasing number of patients presenting to HSAJB with ESRD especially those with diabetic nephropathy is a major concern. Prevention strategies at the primary care level may curb the burden of this chronic disease.

    Full Text Available Background/Aim. The main characteristic of matrix metalloproteinases (MMPs is the degradation of extracellular matrix. Synthesis of MMPs has been reported in coronary atherosclerotic lesions in patients with coronary disease (CD suggesting a pathogenic role of MMPs in its development. Recently there is increasing evidence that gelatinase A (pro MMP-2 and gelatinase B (proMMP-9 play a pathogenic role in the development of the atherosclerotic plaques. The aim of the study was to determine, by the use of a gel image system, a possible presence of active gelatinases in the serum of the patients with CD, as well as if their activity is higher in these patients than in healthy people. Methods. By gelatin zymography we analyzed the activity of proMMP-2 and proMMP-9 in the serum of 50 patients with various coronary artery disease stages and in the serum of 15 healthy controls. The activity was measured by using a gel image system (Kodak Image 1D 3.6.. Results. ProMMP-2 and proMMP-9 activity was significantly higher in the serum of patients with CD compared to controls. There was higher activity of MMP-2 and MMP-9 in the serum of patients with acute myocardial infarction (AMI compared to patients with stable angina pectoris, as well as higher proMMP-9 activity in patients with unstable angina pectoris compared to patients with stable angina pectoris. Conclusion. ProMMP-2 and proMMP-9 participate in processes associated with destabilizing plaques and understanding the processes of MMPs activation and regulation may have significant benefits in clinical interpretation. The reported higher proMMP-2 and proMMP-9 activity in the serum of patients with CD suggests a role of proMMP-2 and proMMP-9 in prognostic stratification of these patients and in designing new drugs.

    Full Text Available Despite decades of research, a full understanding of chronic kidney disease (CKD-end stage renal disease (ESRD progression remains elusive. The common consensus is a predictable, linear, progressive and time-dependent decline of CKD to ESRD. Acute kidney injury (AKI on CKD is usually assumed to be transient, with recovery as the expected outcome. AKI-ESRD association in current nephrology literature is blamed on the so-called "residual confounding." We had previously described a relationship between AKI events and rapid onset yet irreversible ESRD happening in a continuum in a high-risk CKD cohort. However, the contribution of the syndrome of rapid onset-ESRD (SORO-ESRD to incident United States ESRD population remained conjectural. In this retrospective analysis, we analyzed serum creatinine trajectories of the last 100 consecutive ESRD patients in 4 Mayo Clinic chronic hemodialysis units to determine the incidence of SORO-ESRD. Excluding 9 patients, 31 (34% patients, including two renal transplant recipients, had SORO-ESRD: 18 males and 13 females age 72 (range 50-92 years. Precipitating AKI followed pneumonia (8, acutely decompensated heart failure (7, pyelonephritis (4, post-operative (5, sepsis (3, contrast-induced nephropathy (2, and others (2. Time to dialysis was shortest following surgical procedures. Concurrent renin angiotensin aldosterone system blockade was higher with SORO-ESRD - 23% versus 5%, P = 0.0113. In conclusion, SORO-ESRD is not uncommon among the incident general US ESRD population. The implications for ESRD care planning, AV-fistula-first programs, general CKD care and any associations with renal ageing/senescence warrant further study.

    Radiologic contrast media can cause acute renal failure, but whether their repeated use is associated with end-stage renal disease (ESRD) is unknown. We compared 716 incident case subjects of treated ESRD with 361 control subjects, frequency matched on age, drawn from the general population (age, 20-65 years). Participants were interviewed by telephone regarding their previous exposure (before initiation of dialysis for case subjects and the study interview for control subject) to various imaging procedures. As expected, the case subjects reported having more imaging procedures of the kidneys than did control subjects. Excluding persons who had been subjected to examinations of their kidney from the analysis and adjusting for ultrasound examinations and several possible confounders, persons who had a history of one [odds ratio (OR), 2.0; 95% confidence interval (CI), 1.0, 4.0], 2 or 3 (OR, 2.6; 95% CI, 1.2,5.9), or 4 or more (OR, 3.6; 95% CI, 1.0, 12.5) radiocontrast examinations were at higher risk of treated ESRD than persons who reported not having had such procedures. Ultrasound examinations and a history of barium enema were not associated with an increased risk of treated ESRD. In the current study, a graded association was present between increasing exposure to radiologic contrast media and higher risk of treated ESRD. Whether exposure to contrast media accelerates progression to ESRD or is merely a noncausal accompaniment to multiple disease processes occurring concurrently cannot be determined from our observational data. However, if these results are confirmed in future prospective studies, they will have important clinical implications.

    Viscosity, an important determinant of microcirculatory hemodynamics, is related to hematocrit (HCT), and may be altered by renal failure or its treatment. To assess these factors, we studied the effect of dialysis on the viscosity of whole blood, plasma, and reconstituted 70% HCT blood of eight continuous ambulatory peritoneal dialysis (CAPD) and nine hemodialysis (HD) patients under steady shear flow conditions at different shear rates, before and after dialysis, compared with nine normal subjects. The density of the red blood cells (RBCs), a marker of cell hydration, was measured in HD patients by a nonaqueous differential floatation technique. Whole blood viscosity was higher in controls than patients, and correlated with HCT before treatment (P less than 0.05) at shear rates of 11.5 to 230 s-1) in HD patients, and 23 to 230 s-1 in all end-stage renal disease (ESRD) patients. In contrast, whole blood viscosity correlated with HCT in CAPD patients only at the lowest shear rates (2.3 and 5.75 s-1, P less than 0.05). Plasma viscosity was higher in CAPD patients than both HD patients before treatment and controls (P less than 0.05, analysis of variance [ANOVA]), despite lower plasma total protein, albumin, and similar fibrinogen concentration compared with HD patients. When all samples were reconstituted to 70% HCT, CAPD patients had higher whole blood viscosity than control subjects'. The high HCT blood viscosity of the ESRD patients was higher than control subjects' at capillary shear rates, suggesting increased RBC aggregation and decreased RBC deformability in patients with renal disease.(ABSTRACT TRUNCATED AT 250 WORDS)

    Chronic kidney disease (CKD) and end-stage renal disease (ESRD) have emerged as a worldwide public health problem. Due to the remarkably higher incidence and prevalence of this chronic disease in Taiwan than in other countries, CKD/ESRD has contributed to a significant health burden in Taiwan. Patients with CKD/ESRD have an increased risk of coronary artery disease (CAD) and acute coronary syndrome (ACS) compared to the normal population. Patients with ACS alone can present differently than patients with ACS and CKD/ESRD. Also, due to the lower prevalence of chest pain and ST-segment elevation, CKD/ESRD patients were more difficult to diagnose than other patients. Furthermore, whether advances in ACS management with medical therapy and an early invasive approach could improve patient outcomes with CKD/ESRD is not known. The use of antiplatelets such as aspirin and other antithrombotic agents might reduce the incidence of ACS or stroke in CKD patients. However, such use could also increase bleeding risk and even increase the likelihood of mortality, especially in dialysis patients. While recent clinical data suggest the potential benefit of aggressive management with coronary intervention for CAD and ACS in this category of patients, further clinical studies are still indicated for the proper medical strategy and revascularization therapy to improve the outcomes of CAD and ACS in CKD/ESRD patients, both in Taiwan and worldwide.

    From 1983 through 1989, 141 untreated patients with Hodgkin's disease underwent CT of the abdomen. They subsequently underwent staging laparotomy plus splenectomy and multiple biopsies of liver and lymph nodes, at the Institute of Radiology and Hematology, University 'La Sapienza', Rome. CT results were compared with surgical findings to evaluate CT sensitivity, specificity, and overall accuracy. The cases from this series were divided into two groups depending on the characteristics of the CT scanners employed. From 1983 to 1985, 78 patients were examined with 3nd-generation CT units; from 1986 to 1989, 63 patients underwent CT performed with 3rd-generation scanner. The results from the two groups were analyzed according to these parameters. A total number of 622 biopsies were performed, of spleen, liver and lymph nodes. CT sensitivity, specificity, and overall accuracy were: 22.9% (group I) vs 43.7% (group II), 83.1% vs 92%, and 68.4% vs 81.2% for lymph nodes; 28.1% vs 36.3%, 93.5% vs 98%, and 66.7% vs 87.3% for the spleen, and 12.5% vs 42.8%, 97.1% vs 98.2% and 88.5% vs 92.1% for the liver. Our results demonstrate an obvious increase in reliability with newer units, even though a high percentage of false-negatives were still observed in our series, which caused understaging in 19.4% of cases vs 24.4 in group I

    Full Text Available Aim. This study seeks to review the psychosocial factors affecting patients with end-stage kidney disease (ESKD from a tertiary hospital in Australia. Methods. We audited patients with ESKD, referred to social work services from January 2012 to December 2014. All patients underwent psychosocial assessments by one, full-time renal social worker. Patient demographics, cumulative social issues, and subsequent interventions were recorded directly into a database. Results. Of the 244 patients referred, the majority were >60 years (58.6%, male (60.7%, born in Australia (62.3%, on haemodialysis (51.6%, and reliant on government financial assistance (88%. Adjustment issues (41%, financial concerns (38.5%, domestic assistance (35.2%, and treatment nonadherence (21.3% were the predominant reasons for social work consultation. Younger age, referral prior to start of dialysis, and unemployment were significant independent predictors of increased risk of adjustment issues (p=0.004, <0.001, and =0.018, resp.. Independent risk factors for treatment nonadherence included age and financial and employment status (p=0.041, 0.052, and 0.008, resp.. Conclusion. Psychosocial and demographic factors were associated with treatment nonadherence and adjustment difficulties. Additional social work support and counselling, in addition to financial assistance from government and nongovernment agencies, may help to improve adjustment to the diagnosis and treatment plans as patients approach ESKD.

    We investigated the prevalence of sarcopenia in elderly patients with end-stage renal disease (ESRD) and its relationship with various markers of nutrition, cognitive function, depressive symptoms, inflammation and β2-microglobulin. A cross-sectional study was conducted with 95 patients having ESRD aged over 50 years. Sarcopenia was defined as a decline in both muscle mass and strength. The mean age was 63.9 ± 10.0 years; 56.8% were men and 52.6% had diabetes. Sarcopenia was highly prevalent in elderly patients with ESRD (37.0% in men and 29.3% in women). Subjective Global Assessment (SGA), inflammatory markers and β2-microglobulin levels were significantly associated with sarcopenia, even after adjustment for age, gender, diabetes, and body mass index. Additionally, patients with depressive symptoms showed a higher risk of sarcopenia relative to those without depressive symptoms (odds ratio, OR = 6.87, 95% confidence interval, CI = 2.06-22.96) and sarcopenia was more likely to be present in patients with mild cognitive dysfunction (OR = 6.35, 95% CI = 1.62-34.96). Sarcopenia is highly prevalent in elderly patients with ESRD and is closely associated with SGA, inflammatory markers, β2-microglobulin, depression and cognitive dysfunction.

    1999-01-01

    In the United States, there is a large and growing population of patients undergoing dialysis because of end-stage renal disease (ESRD). These patients present special management considerations for dentists, including antibiotic prophylaxis for the prevention of bacterial endocarditis (BE). ESRD patients, particularly those with an arteriovenous shunt for hemodialysis access, are predisposed to valvular endocarditis. Thus, BE prevention is the primary goal of antibiotic prophylaxis prior to dental or other invasive procedures in these patients. Bacteremia may predispose to infection of synthetic vascular access grafts, although this form of endovascular infection in ESRD patients has not been as well-characterized as BE. Antibiotic prophylaxis may be of some benefit for prevention of synthetic graft infections as well as BE. Poor dentist and physician compliance with BE prophylaxis regimens, as well as errors in dosing, timing, or duration of prophylaxis, have been reported. These problems are of particular concern in the treatment of chronically ill patients. In this article, we review the rationale for prophylactic antibiotic therapy prior to dental procedures in ESRD patients with vascular access. We also elaborate on the current American Heart Association guidelines for BE prophylaxis, and address special considerations for ESRD patients.

    Although possessing different anthropological origins, there are similarities in the epidemiology of end-stage kidney disease (ESKD) among the indigenous peoples of Australia (the Australian Aborigines and Torres Strait Islanders) and New Zealand (Maori and Pacific Peoples). In both countries there is a substantially increased rate of ESKD among these groups. This is more marked in Australia than in New Zealand, but in both countries the relative rate (in comparison to non-indigenous rates) as well as absolute rate have nearly stabilized in recent years. The excess risk affects females particularly-in contrast to the non-indigenous picture. Among Aboriginal and Torres Strait Islander people in Australia, there is a strong age interaction, with the most marked risk being among those aged 25 to 45 years. Indigenous peoples are less likely to be treated with home dialysis, and much less likely to receive a kidney transplant. In particular, rates of living donation are very low among indigenous groups in both countries. Outcomes during dialysis treatment and during transplantation are inferior to those of nonindigenous ones, even after adjustment for the higher prevalence of comorbidities. The underlying causes for these differences are complex, but the slowing and possible stabilization of incident rate changes is heartening.

    Full Text Available Background. The purpose of this study was to analyze the factors associated with receiving peritoneal dialysis (PD in patients with incident end-stage renal disease (ESRD in a hospital in Southern Taiwan. Methods. The study included all consecutive patients with incident ESRD who participated in a multidisciplinary predialysis education (MPE program and started their first dialysis therapy between January 1, 2008, and June 30, 2013, in the study hospital. We provided small group teaching sessions to advanced CKD patients and their family to enhance understanding of various dialysis modalities. Multivariate logistic regression models were used to analyze the association of patient characteristics with the chosen dialysis modality. Results. Of the 656 patients, 524 (80% chose hemodialysis and 132 chose PD. Our data showed that young age, high education level, and high scores of activities of daily living (ADLs were positively associated with PD treatment. Patients who received small group teaching sessions had higher percentages of PD treatment (30.5% versus 19.5%; P=0.108 and preparedness for dialysis (61.1% versus 46.6%; P=0.090. Conclusion. Young age, high education level, and high ADL score were positively associated with choosing PD. Early creation of vascular access may be a barrier for PD.

    Full Text Available Sporadic Alzheimer’s disease (AD is an emerging chronic illness characterized by a progressive pleiotropic pathophysiological mode of actions triggered during the senescence process and affecting the elderly worldwide. The complex molecular mechanisms of AD not only are supported by cholinergic, beta-amyloid, and tau theories but also have a genetic basis that accounts for the difference in symptomatology processes activation among human population which will evolve into divergent neuropathological features underlying cognitive and behaviour alterations. Distinct immune system tolerance could also influence divergent responses among AD patients treated by immunotherapy. The complexity in nature increases when taken together the genetic/immune tolerance with the patient’s brain reserve and with neuropathological evolution from early till advance AD clinical stages. The most promising diagnostic strategies in today’s world would consist in performing high diagnostic accuracy of combined modality imaging technologies using beta-amyloid 42 peptide-cerebrospinal fluid (CSF positron emission tomography (PET, Pittsburgh compound B-PET, fluorodeoxyglucose-PET, total and phosphorylated tau-CSF, and volumetric magnetic resonance imaging hippocampus biomarkers for criteria evaluation and validation. Early diagnosis is the challenge task that needs to look first at plausible mechanisms of actions behind therapies, and combining them would allow for the development of efficient AD treatment in a near future.

We used questionnaire Plutchik-Kellerman-Comte "life style Index". The study involved 257 people (118 women (46% and 139 men (54% aged 18 to 67 years (mean age — 23,5±8,9years. Results. In patients with primary syphilis primary mecha-protection scheme is "denying"; secondary syphilis of skin and mucus-purity membranes— "replacement"; syphilis latent early — "projection"; in patients with late syphilis — intellectualization. Thus, in patients with late forms of syphilis is dominated by more Mature mechanisms of protection (projection, rationalization. Patients with early forms use more primitive mechanisms (denial, substitution. Conclusion. The obtained data may be useful in the choice of methods of psychotherapy, the formation of patients more realistic (ADAP-tive installations for the treatment, restoration of family and other social relations, the prevention of distress and improving the quality of life of patients.

    Resistant hypertension is a common and refractory complication of hemodialysis (HD) patients and is associated with a higher risk of cardiovascular morbidity and mortality. Here we present a case of resistant hypertension treated successfully by nocturnal HD. A 63-year-old female with end-stage kidney disease was hospitalized for severe headache, objective vertigo and persistent vomiting for 1 month on February 6, 2012. She had been on intermittent HD for 3 months, and her blood pressure maintained 200-240/100-130 mm Hg even after using 7 kinds of antihypertensive drugs including olmesartan, benazepril, nitrendipine, arotinolol, terazosin, clonidine and torasemide. A CT of the abdomen revealed a mild hyperplasia of the left adrenal gland (fig. 1). However, plasma renin, angiotensin and aldosterone were all within the normal range. Nocturnal extended HD was initiated with a blood flow rate of 150 ml/min and a dialysis time of 7 h. After 3 months of nocturnal HD, all symptoms were relieved and her systolic blood pressure started to decrease by 10-20 mm Hg. Six months later, the predialysis blood pressure was decreased to 140-160/90-100 mm Hg and the antihypertensive drugs were reduced to 4 kinds. Meanwhile, the blood biochemical parameters including hemoglobin, serum calcium, phosphate and parathyroid hormone were all controlled well during 2 years of treatment. This case indicates that nocturnal extended HD is probably a promising and effective choice for resistant hypertension in HD patients.

    Full Text Available Abstract Background End-stage lung disease (ESLD is a frequent cause of death. What are the differences in the supports needed by caregivers of individuals with ESLD at end of life versus other life-limiting diagnoses? Methods The South Australian Health Omnibus is an annual, random, face-to-face, cross-sectional survey. In 2002, 2003 and 2005-2007, respondents were asked a range of questions about end-of-life care; there were approximately 3000 survey participants annually (participation rate 77.9%. Responses were standardised for the whole population. The families and friends who cared for someone with ESLD were the focus of this analysis. In addition to describing caring, respondents reported additional support that would have been helpful. Results Of 1504 deaths reported, 145 (9.6% were due to ESLD. The ESLD cohort were older than those with other 'expected' causes of death (> 65 years of age; 92.6% versus 70.6%; p physical care, information provision, and emotional and spiritual support. Conclusions Caregiver needs were similar regardless of the underlying diagnosis although access to palliative care specialist services occurred less often for ESLD patients. This was despite significantly longer periods of time for which care was provided.

    Full Text Available Parkinson’s disease (PD is a progressive neurodegenerative disorder that is characterized by dopamine depletion in the striatum. One consistent pathophysiological hallmark of PD is an increase in spontaneous oscillatory activity in the basal ganglia thalamocortical networks. We evaluated these effects using resting state functional connectivity MRI (fcMRI in mild to moderate stage Parkinson’s patients on and off L-DOPA and age-matched controls using six different striatal seed regions. We observed an overall increase in the strength of cortico-striatal functional connectivity in PD patients off L-DOPA compared to controls. This enhanced connectivity was down-regulated by L-DOPA as shown by an overall decrease in connectivity strength, particularly within motor cortical regions. We also performed a frequency content analysis of the BOLD signal time course extracted from the six striatal seed regions. PD off L-DOPA exhibited increased power in the frequency band 0.02 – 0.05 Hz compared to controls and to PD on L-DOPA. The L-DOPA associated decrease in the power of this frequency range modulated the L-DOPA associated decrease in connectivity strength between striatal seeds and the thalamus. In addition, the L-DOPA associated decrease in power in this frequency band also correlated with the L-DOPA associated improvement in cognitive performance. Our results demonstrate that PD and L-DOPA modulate striatal resting state BOLD signal oscillations and corticostriatal network coherence.

    A significant percentage of patients with end-stage renal disease are malnourished and/or muscle wasted. Uremia is associated with decreased protein synthesis and increased protein degradation. Fortunately, nutritional status has been shown to be a modifiable risk factor in the dialysis population. It has long been proposed that exercise could positively alter the protein synthesis-degradation balance. Resistance training had been considered as the only form of exercise likely to induce anabolism in renal failure patients. However, a small, but growing, body of evidence indicates that for some dialysis patients, favourable improvements in muscle atrophy and fibre hypertrophy can be achieved via predominantly aerobic exercise training. Moreover, some studies tentatively suggest that nutritional status, as measured by SGA, can also be modestly improved by modes and patterns of exercise training that have been shown to also increase muscle fibre cross-sectional area and improve functional capacity. Functional capacity tests can augment the information content of basic nutritional status assessments of dialysis patients and as such are recommended for routine inclusion as a feature of all nutritional status assessments.

    Full Text Available To estimate the costs and effectiveness measured in quality-adjusted life years (QALY of kidney transplantation compared with dialysis in adults suffering from end-stage renal disease from the perspective of the Colombian healthcare system, we designed a Markov model with monthly cycles over a five-year time horizon and eight transitional states, including death as an absorbing state. Transition probabilities were obtained from international registries, costs from different local sources [case studies, official tariffs (ISS 2001 + 35% for procedures and SISMED for medications]. Data were validated by an expert panel and we performed univariate, multivariate and probabilistic sensitivity analyses. Effectiveness indicators were months of life gained, months of dialysis averted and deaths prevented. The annual discount rate was 3% and the cost-utility threshold (willingness to pay was three times gross domestic product (GDP = USD 20,000 per QALY. The costs were adopted in US dollars (USD using the 2012 average exchange rate (1 USD = COP$ 1798. The discounted average total cost for five years was USD 76,718 for transplantation and USD 76,891 for dialysis, with utilities 2.98 and 2.10 QALY, respectively. Additionally, renal transplantation represented 6.9 months gained, 35 months in dialysis averted per patient and one death averted for each of the five patients transplanted in five years. We conclude that renal transplantation improves the overall survival rates and quality of life and is a cost-saving alternative compared with dialysis.

    The incidence and prevalence of end-stage renal disease (ESRD) are extremely high in Taiwan. It is an interesting fact that both the husband and wife in some families of Taiwan suffer from ESRD. Therefore, we attempted to identify the potential risk factors of such couples. This is a retrospective observational study. Six couples receiving maintenance dialysis in our hospital from 1996 to 2006 were enrolled in this study. Detailed medical history; drugs history including over-the-counter drugs (OCD), analgesics and herbal remedies; occupational history and onset of transitional cell carcinoma (TCC) were recorded. These data are correlated with pre-dialysis laboratory findings. The outcomes of dialysis and TCC were also recorded and analyzed. Two males were Chinese herbal medicine practitioners. All the patients (12/12) had taken Chinese herbs and most of them (10/12) had also taken OCD (especially cold remedies and analgesics). We found all of them had bilateral contracted kidneys, mild proteinuria and trace glucosuria. One patient's renal biopsy revealed Chinese herb nephropathy. Four patients (33%) suffered from TCC. Three patients expired during follow up due to hyperkalemia, extensive TCC and suicide, respectively. The prevalence of Chinese herbs or compound analgesics abuse is high in couples with ESRD. The clinical features and high incidence of TCC are compatible with drug related chronic tubulointerstitial nephritis. Abuse of offending agents should be considered as a risk factor in family members with ESRD.

    Full Text Available Hemodialysis is a modality of blood filtration in which accumulated toxins and water are removed from the body. This treatment is indicated for patients at the end stage of renal disease. Vascular access complications are responsible for 20–25% of all hospitalizations in dialyzed patients. The occurrence of thrombosis in the vascular access is a serious problem that may severely compromise or even make the hemodialysis impossible, which is vital for the patient. The aim of this study was to investigate inflammatory profile in patients undergoing hemodialysis as well as the association between these alterations and vascular access thrombosis. A total of 195 patients undergoing hemodialysis have been evaluated; of which, 149 patients had not experienced vascular access thrombosis (group I and 46 patients had previously presented this complication (group II. Plasma levels of cytokines including interleukin (IL- 2, IL-4, IL-5, IL-10, TNF-α, and IFN-γ were measured by cytometric bead array. Our results showed that patients with previous thrombotic events (group II had higher levels of the IL-2, IL-4, IL-5, and IFN-γ when compared to those in group I. Furthermore, a different cytokine signature was detected in dialyzed patients according to previous occurrences or not of thrombotic events, suggesting that elevated levels of T-helper 1 and T-helper 2 cytokines might, at least in part, contribute to this complication.

    Studies have shown that protein-energy malnutrition (PEM) is a strong predictor of total mortality among patients with end-stage renal disease (ESRD). The aim of this study is to assess the relationship between nutritional indices and cardiovascular (CV) mortality among patients with ESRD by using data from the US Renal Data System (USRDS) Dialysis Morbidity and Mortality Study Wave I (DMMS-1). Demographic and medical data were abstracted from 5,058 patients who participated in the USRDS DMMS-1. Nutritional measurements of interest included subjective assessment of malnutrition, serum albumin level, body mass index (BMI), and cholesterol level. The USRDS provided follow-up data on mortality through July 1998. The Cox proportional hazard model was used to estimate the risk for CV death associated with nutritional markers. The risk for CV death was 39% greater for each 1-g/dL (10-g/L) decrement in serum albumin level (95% confidence interval [CI], 1.20 to 1.60; P history of CVD at the study start. Both PEM at baseline and worsening PEM over time are associated with a greater risk for CV death. This finding persists among dialysis patients without preexisting CVD at baseline.

    Malnutrition is found in almost 100% of patients with end stage liver disease (ESLD) awaiting transplantation and malnutrition before transplantation leads to higher rates of post-transplant complications and worse graft survival outcomes. Reasons for protein energy malnutrition include several metabolic alterations such as inadequate intake, malabsorption, and overloaded expenditure. And also, stress from surgery, gastrointestinal reperfusion injury, immunosuppressive therapy and corticosteriods use lead to delayed bowl function recovery and disorder of nutrients absorption. In the pretransplant phase, nutritional goals include optimization of nutritional status and treatment of nutrition-related symptoms induced by hepatic decompensation. During the acute post-transplant phase, adequate nutrition is required to help support metabolic demands, replenish lost stores, prevent infection, arrive at a new immunologic balance, and promote overall recovery. In a word, it is extremely important to identify and correct nutritional deficiencies in this population and provide an adequate nutritional support during all phases of liver transplantation (LT). This study review focuses on prevalence, nutrition support, evaluation, and management of perioperative nutrition disorder in patients with ESLD undergoing LT.

    Full Text Available The aim of this retrospective, nationwide, matched cohort study was to investigate the association of serous retinal detachment with having end-stage renal disease (ESRD while on dialysis. The cohort study included 94,024 patients with ESRD on dialysis registered between January 2000 to December 2009 in the Taiwan National Health Insurance Research Database. An age- and sex-matched control group comprised 94,024 patients selected from the Taiwan Longitudinal Health Insurance Database 2000. Information for each patient was collected from the index date until December 2011. Twenty-seven ESRD patients and 11 controls developed serous retinal detachment (P < 0.001 during follow-up, demonstrating a significantly increased risk of serous retinal detachment in patients with ESRD on dialysis compared with controls (incidence rate ratio = 3.39, 95% confidence interval [CI] = 1.68-6.83. After adjustment for potential confounders, patients were 3.86 times more likely to develop serous retinal detachment than the full cohort (adjusted HR = 3.86, 95% CI = 1.15-12.96. In conclusion, patients with ESRD on dialysis demonstrate an increased risk of serous retinal detachment. Interdisciplinary collaboration between nephrologists and ophthalmologists is important to deal with serous retinal detachment in patients with ESRD on dialysis and prevent impairments of visual acuity.

    Full Text Available Among patients with end-stage renal disease (ESRD, few studies have examined the use of complementary and alternative medicine (CAM and patients’ interest in learning mind-body interventions to address health issues. We surveyed 89 adult patients (response rate 84% at an outpatient hemodialysis center in Brookline, MA, USA regarding the utilization of CAM, including mind-body practices, and willingness to learn mind-body practices. Of respondents, 47% were female, 63% were black, and mean age was 62 years. 61% reported using CAM for health in their lifetime, and 36% reported using CAM within a month of the survey. The most frequent CAM modalities reported in ones’ lifetime and in the last month were mind-body practices (42% and 27%, resp.. Overall lifetime CAM use did not differ significantly by sex, race, dialysis vintage, diagnosis of ESRD, employment status, or education level. Subjects reported that mind-body interactions were very important to health with a median score of 9 on a 10-point Likert scale (ranging from 0 for not important to 10 for extremely important. Most patients (74% reported interest in learning mind-body practices during maintenance hemodialysis. In summary, CAM use, particularly mind-body practice, is frequent among patients with ESRD providing opportunities for future clinical research.

    Many patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD) experience depression. Depression influences patient quality of life (QOL), dialysis compliance, and medical comorbidity. We developed and applied a group cognitive behavioral therapy (CBT) program including mindfulness meditation for ESRD patients undergoing HD, and measured changes in QOL, mood, anxiety, perceived stress, and biochemical markers. We conducted group CBT over a 12-week period with seven ESRD patients undergoing HD and suffering from depression. QOL, mood, anxiety, and perceived stress were measured at baseline and at weeks 8 and 12 using the World Health Organization Quality of Life scale, abbreviated version (WHOQOL-BREF), the Beck Depression Inventory II (BDI-II), the Hamilton Rating Scale for Depression (HAM-D), the Beck Anxiety Inventory (BAI), and the Perceived Stress Scale (PSS). Biochemical markers were measured at baseline and after 12 weeks. The Temperament and Character Inventory was performed to assess patient characteristics before starting group CBT. The seven patients showed significant improvement in QOL, mood, anxiety, and perceived stress after 12 weeks of group CBT. WHOQOL-BREF and the self-rating scales, BDI-II and BAI, showed continuous improvement across the 12-week period. HAM-D scores showed significant improvement by week 8; PSS showed significant improvement after week 8. Serum creatinine levels also improved significantly following the 12 week period. In this pilot study, a CBT program which included mindfulness meditation enhanced overall mental health and biochemical marker levels in ESRD patients undergoing HD.

    To describe the prevalence, diagnosis, treatment, and outcomes of end stage liver disease (ESLD) patients with severe epistaxis thought to be severe upper gastrointestinal hemorrhage (UGIH). This observational single center study included all consecutive patients with ESLD and epistaxis identified from consecutive subjects hospitalized with suspected UGIH and prospectively enrolled in our databases of severe UGIH between 1998 and 2011. A total of 1249 patients were registered for severe UGIH in the data basis, 461 (36.9%) were cirrhotics. Epistaxis rather than UGIH was the bleeding source in 20 patients. All patients had severe coagulopathy. Epistaxis was initially controlled in all cases. Fifteen (75%) subjects required posterior nasal packing and 2 (10%) embolization in addition to correction of coagulopathy. Five (25%) patients died in the hospital, 12 (60%) received orthotopic liver transplantation (OLT), and 3 (15%) were discharged without OLT. The mortality rate was 63% in patients without OLT. Severe epistaxis in patients with ESLD is (1) a diagnosis of exclusion that requires upper endoscopy to exclude severe UGIH; and (2) associated with a high mortality rate in patients not receiving OLT.

    Over the last few decades there has been a revival of interest in virtue ethics, with the emphasis on the virtuous caregiver. This paper deals with the 'virtuous patient', specifically the patient with End Stage Renal Disease (ESRD). We believe that a virtue approach provides insights not available to current methods of studying coping styles and coping strategies. Data are derived from seven semi-structured in-depth interviews. The transcripts of the interviews were subjected to an Interpretative Phenomenological Analysis (IPA). The focus of the analysis was on 'living well with chronic illness.' It appears that the moral challenges faced by patients with ESRD are manifold. When they are invited to tell the story of their illness, they do not explicitly speak of virtues, but they often refer to moral qualities, and to attitudes that can be regarded as virtuous. We identify several such concepts in the narratives of patients with ESRD. We conclude that the Aristotelian model of virtue ethics is particularly descriptively (and possibly also normatively) relevant to the explanation of the life narratives and the moral challenges of patients with an ESRD.

    Physical frailty, as measured by the Fried Frailty Index, is increasingly recognized as a critical determinant of outcomes in patients with cirrhosis. However, its utility is limited by the inclusion of self-reported components. We aimed to identify performance-based measures associated with frailty in patients with cirrhosis. Patients with cirrhosis, aged 50 years or older, underwent: 6-minute walk test (cardiopulmonary endurance), chair stands in 30 seconds (muscle endurance), isometric knee extension (lower extremity strength), unipedal stance time (static balance), and maximal step length (dynamic balance/coordination). Linear regression associated each physical performance test with frailty. Principal components exploratory factor analysis evaluated the interrelatedness of frailty and the 5 physical performance tests. Of 40 patients with cirrhosis, with a median age of 64 years and Model for End-stage Liver Disease (MELD) MELD of 12.10 (25%) were frail by Fried Frailty Index ≥3. Frail patients with cirrhosis had poorer performance in 6-minute walk test distance (231 vs 338 m), 30-second chair stands (7 vs 10), isometric knee extension (86 vs 122 Newton meters), and maximal step length (22 vs 27 in. (P ≤ 0.02 for each). Each physical performance test was significantly associated with frailty (P test to a single factor-frailty. Frailty in cirrhosis is a multidimensional construct that is distinct from liver dysfunction and incorporates endurance, strength, and balance. Our data provide specific targets for prehabilitation interventions aimed at reducing frailty in patients with cirrhosis in preparation for liver transplantation.

    To explore the relationship between physical activity and risk of end-stage kidney disease (ESKD). We analysed data on a prospective cohort of 59,552 Chinese adults aged 45-74 years enrolled in the Singapore Chinese Health Study. Information on physical activity was collected with a structured questionnaire. Physically active individuals were defined as those who engaged in any moderate activities for 2 h or more per week and any strenuous activities 30 min or more per week. Incident ESKD was identified via record linkage with the Singapore Registry of Birth and Death and Singapore Renal Registry. Cox proportional hazards regression method was used for analysis for risk of incident ESKD alone or ESKD plus death associated with physical activity. During a median follow-up of 15.3 years, a total of 642 incident ESKD occurred, and 9808 study participants died. A 24% lower adjusted risk of ESKD (hazard ratio: 0.76; 95% confidence interval: 0.62-0.93) was associated with moderate or strenuous physical activities compared with no regular physical activity. This association appeared to be dose dependent with the lowest risk for subjects at highest intensity of physical activity (P trend <0.003). Similar results were observed for risk of ESKD plus death. Higher levels of physical activity are associated with lower risk of ESKD. Our findings highlight the role of physical activity for prevention of ESKD, which deserves further evaluation in intervention trials. © 2014 Asian Pacific Society of Nephrology.

    Healthcare for end-stage renal disease (ESRD) is intensive, expensive, and provided in both the public and private sector. Using a societal perspective, we examined healthcare costs and health outcomes for Department of Veterans Affairs (VA) ESRD patients comparing those who received hemodialysis care at VA versus private sector facilities. Dialysis patients were recruited from 8 VA medical centers from 2001 through 2003 and followed for 12 months in a prospective cohort study. Patient demographics, clinical characteristics, quality of life, healthcare use, and cost data were collected. Healthcare data included utilization (VA), claims (Medicare), and patient self-report. Costs included VA calculated costs, Medicare dialysis facility reports and reimbursement rates, and patient self-report. Multivariable regression was used to compare costs between patients receiving dialysis at VA versus private sector facilities. The cohort comprised 334 patients: 170 patients in the VA dialysis group and 164 patients in the private sector group. The VA dialysis group had more comorbidities at baseline, outpatient and emergency visits, prescriptions, and longer hospital stays; they also had more conservative anemia management and lower baseline urea reduction ratio (67% vs. 72%; Pprivate sector dialysis group (Pprivate sector settings is critical in informing health policy options for patients with complex chronic illnesses such as ESRD.

    There is a growing number of people with advanced chronic health conditions and with palliative care needs who die without their health and social needs satisfied. This is enough to redefine the traditional models of care in order to focus on the person, rather than on the disease. In these new models, the important role of nursing is unquestionably to promote an approach based on comprehensive care, coordination and continuity, and at a social health level appropriate to respond to the care of patients who require complex long-term care. The nurse contribution in the end stages of chronic conditions must be in the value of care. Taking care of someone is to be concerned about them. And this is related to attitude, commitment and responsibility. In the care of patients who live in a situation of extreme vulnerability, it is possible to help them feel warmth, confident, relieve their suffering, respect their autonomy, and help them them find sense and hope, through daily tasks. With gestures, words and facial expressions that go with this care, it is possible to preserve patient dignity. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    Full Text Available Depression is the most common psychiatric complication in patients with end-stage renal disease (ESRD. Sarcopenia, defined as loss of muscle mass and strength, is expected to be associated with depression, because both are closely linked to physical inactivity and functional impairment. We investigated the association of sarcopenia with depression in patients with ESRD. A total of 115 patients undergoing hemodialysis (HD were included in this study. Muscle mass was assessed by lean tissue index (LTI using portable whole body bioimpedance spectroscopy, and muscle strength was measured with handgrip strength (HGS. Depression was defined as Beck Depression Inventory-II (BDI-II score ≥16. About 60% of prevalent HD patients had depression. Compared to subjects without depression, depressed patients had a higher prevalence of sarcopenia (45.5 vs. 8.2%, p<0.001 and significantly increased serum IL-6 and hs-CRP level. However, (prealbumin and body mass index (BMI failed to correlate with BDI-II. HGS and LTI had a consistent negative effect on BDI-II even after adjusting other parameters including inflammation. In multivariate analysis, lower , increased IL-6 and β2-microglobulin,and sarcopenia were significant predictors for depression; sarcopenia was most powerful [odds ratio 9.01, 95% CI 3.60-12.22, p=0.001]. In conclusion, the prevalence of sarcopenia and depression was considerably high and and the presence of sarcopenia was an important predictor for depression.

    Long-term use of aluminum-based phosphate binders and trace aluminum contamination of dialysate solution have led to increased body burden of this metal in patients with end-stage renal disease. Aluminum accumulates in bone and has been associated with the development of a renal osteodystrophy, called aluminum-induced osteomalacia. At present, bone biopsy is the method of diagnosis of this condition. When examined by quantitative histomorphometry, the aluminum accumulation was reported to correlate with the severity of the osteomalacia. This project was therefore undertaken to investigate the possibility of developing a non-invasive technique using neutron activation analysis for the direct in vivo assessment of bone aluminum levels. A bilateral exposure of the patient's hand is performed at the patient port of the Brookhaven Medical Research Reactor. The induced activity is then counted for 5 min using four 4'' x 4'' x 16'' NaI(T1) detectors arranged in a quasi-4! geometry. In addition to Al, Ca is also detected and serves as each individual's internal standard for the volume of bone mass irradiated. The Al/Ca ratio provides an index of the amount of elevated aluminum per unit bone mass. When this ratio is multiplied by the total body calcium value, an estimate of total skeletal aluminum is obtained. These measurements will be presented for a pilot study of ten asymptomatic renal patients

    Anxiety is an unpleasant emotion affecting patients with cancer, and there are various ways of coping with it. Little is known about the relationship between the anxiety level and physical, somatic or spiritual (e.g. religiousness) factors in breast cancer patients at different stages of the disease. The purpose of the study was to assess the intensity of anxiety at different stages of breast cancer, to define the relationship between religiousness and physical (somatic) condition and anxiety in the study subjects and to find out if religiousness is an effective coping strategy at any breast cancer stage. The study involved 180 women aged between 28 and 77, who were qualified to one of five study groups, according to their disease stage. The following research instruments were used: the State-Trait Anxiety Inventory (STAI), Scale of Personal Religiousness, the Rotterdam Symptom Checklist as well as medical history and data from patients' medical records. There is a significant correlation between state anxiety and trait anxiety measured by STAI in study groups. Breast cancer stage differentiates the study groups in respect of revealed anxiety level. Somatic condition has no significant impact on the intensity of anxiety in terminal breast cancer patients. Amongst the studied variables, only religiousness is an important factor that influences the anxiety level of end-stage cancer patients. The obtained results allow us to conclude that: (a) religiousness is an effective factor of coping with anxiety only of the end-stage breast cancer patients; (b) cancer stage is a differentiating factor in respect of revealed anxiety level in study subjects; (c) exacerbation of somatic symptoms does not influence the anxiety level in terminal cancer patients and at disease-free period.

    Despite the high prevalence of chronic kidney disease in the elderly population, few data are available on the frequency of secondary hyperparathyroidism in the Spanish population affected by this problem. We undertook a study on this issue in patients attending the internal medicine departments in our area. An observational, cross-sectional survey performed at internal medicine departments on 415 patients with stage 3 and 4 chronic kidney disease. Clinical history and risk factors were collected using a standardized protocol. Serum creatinine, phosphate, calcium, intact parathormone (PTH) and 25-hydroxy-cholecalciferol (25-OH-vitD) levels were measured in all patients. Among stage 3 patients, 62.9% had PTH levels ≥70pg/mL and 32.7% levels ≥110pg/mL. Median PTH level in stage 4 patients was 120pg/mL (p <0.001), and 77.9% of these patients had PTH ≥70pg/mL (p <0.001) and 54.1% ≥110pg/mL (p=0.015). Adequate 25-hydroxy-cholecalciferol levels were found in only 7.2% of stage 3 patients and 4.1% of stage 4 patients. Only 7.2% of stage 3 patients had hyperphosphatemia, as compared to 25.4% of stage 4 patients (p <0.001). Hyperparathyroidism is a common complication of stage 3 and 4 chronic kidney disease which is not associated to detectable changes in serum calcium and phosphate levels. It is therefore advisable to measure PTH levels in all patients with decreased glomerular filtration rate. Copyright © 2015 SEEN. Published by Elsevier España, S.L.U. All rights reserved.

Our aim was to validate this staging approach using data from three surveys in The Copenhagen City Heart Study, in which a sample of the general population was examined at baseline and in which, after 5 and 15 years, spirometry was performed at all surveys. Criteria for GOLD Stage 0 was fulfilled....... Further analyses using multivariate logistic regression analysis confirmed that GOLD Stage 0 was not identifying subsequent airways obstruction. When analyzing FEV(1) decline, Stage 0 carried a risk of excess decline. GOLD Stage 0 was not a stable feature, which may explain the lack of predictive value...

    Mucopolysaccharidosis type IIIB syndrome (also known as Sanfilippo type B syndrome) is a lysosomal storage disease resulting in progressive deterioration of cognitive acquisition after age 2-4 years. No treatment is available for the neurological manifestations of the disease. We sought to assess the safety and efficacy of a novel intracerebral gene therapy. Local regulatory authorities in France allowed inclusion of up to four children in this phase 1/2 study. Treatment was 16 intraparenchymal deposits (four in the cerebellum) of a recombinant adenoassociated viral vector serotype 2/5 (rAAV2/5) encoding human α-N-acetylglucosaminidase (NAGLU) plus immunosuppressive therapy. We assessed tolerance, neurocognitive progression, brain growth, NAGLU enzymatic activity in CSF, and specific anti-NAGLU immune response for 30 months after surgery. This trial is registered with EudraCT, number 2012-000856-33, and the International Standard Clinical Trial Registry, number ISRCTN19853672. Of seven eligible children, the four youngest, from France (n=2), Italy (n=1), and Greece (n=1), aged 20, 26, 30, and 53 months, were included between February, 2012, and February, 2014. 125 adverse events were recorded, of which 117 were treatment emergent and included six classified as severe, but no suspected unexpected serious adverse drug reactions were seen. Vector genomes were detected in blood for 2 days after surgery. Compared with the natural history of mucopolysaccharidosis type III syndromes, neurocognitive progression was improved in all patients, with the youngest patient having function close to that in healthy children. Decrease in developmental quotient was -11·0 points in patient one, -23·0 in patient two, -29·0 in patient three, and -17·0 in patient four, compared with -37·7 in the natural history of the disease. NAGLU activity was detected in lumbar CSF and was 15-20% of that in unaffected children. Circulating T lymphocytes that proliferated and produced tumour

    Retinopathy of prematurity (ROP) is a retinal vascular disease that occurs in infants with short gestational age and low birth weight and may lead to retinal detachment and blindness. Missense mutations in the Norrie disease (ND) gene have been associated with the risk of progression to advanced stages in cases of ROP from the US and also in clinically similar ND and familial exudative vitreoretinopathy. We have screened two ND gene mutations, namely A105T and Val60Glu, by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and allele-specific PCR methods, respectively, in 210 Kuwaiti premature newborns to replicate these findings in a different ethnic group. In the Kuwaiti premature newborn cohort, 115 of 210 babies had no eye problems and served as controls, while 95 were cases of ROP. In 71 of 95 ROP cases, the disease regressed spontaneously on or before stage 3, while in 24 of 95 ROP cases the disease progressed to advanced stages 4 and 5. In case of missense mutation (A105T), the AA genotype was detected in 96% of controls compared with 87% of ROP cases (NS); similarly no significant difference was found between spontaneously regressed ROP cases and those who progressed to advanced stages. For the Val60Glu mutation, no significant association was detected between the genotype and progression of ROP to advanced stages. Unlike data from the US, our findings from a Kuwaiti cohort of ROP cases and controls suggest a lack of association between the two ND gene mutations (A105T and Val60Glu) and ROP and the risk of progression of the disease to advanced stages.

    Ovarian cancer is a heterogeneous disease and prognosis for apparently similar cases of ovarian cancer varies. Recurrence of the disease in early stage (FIGO-stages I-II) serous ovarian cancer results in survival that is comparable to those with recurrent advanced-stage disease. The aim of this study was to investigate if there are specific genomic aberrations that may explain recurrence and clinical outcome. Fifty-one women with early stage serous ovarian cancer were included in the study. DNA was extracted from formalin fixed samples containing tumor cells from ovarian tumors. Tumor samples from thirty-seven patients were analysed for allele-specific copy numbers using OncoScan single nucleotide polymorphism arrays from Affymetrix and the bioinformatic tool Tumor Aberration Prediction Suite. Genomic gains, losses, and loss-of-heterozygosity that associated with recurrent disease were identified. The most significant differences (p < 0.01) in Loss-of-heterozygosity (LOH) were identified in two relatively small regions of chromosome 19; 8.0-8,8 Mbp (19 genes) and 51.5-53.0 Mbp (37 genes). Thus, 56 genes on chromosome 19 were potential candidate genes associated with clinical outcome. LOH at 19q (51-56 Mbp) was associated with shorter disease-free survival and was an independent prognostic factor for survival in a multivariate Cox regression analysis. In particular LOH on chromosome 19q (51-56 Mbp) was significantly (p < 0.01) associated with loss of TP53 function. The results of our study indicate that presence of two aberrations in TP53 on 17p and LOH on 19q in early stage serous ovarian cancer is associated with recurrent disease. Further studies related to the findings of chromosomes 17 and 19 are needed to elucidate the molecular mechanism behind the recurring genomic aberrations and the poor clinical outcome

    Flortaucipir (tau) positron emission tomography (PET) binding distinguishes individuals with clinically well-established posterior cortical atrophy (PCA) due to Alzheimer disease (AD) from cognitively normal (CN) controls. However, it is not known whether tau-PET binding patterns differentiate individuals with PCA from those with amnestic AD, particularly early in the symptomatic stages of disease. Flortaucipir and florbetapir (β-amyloid) PET imaging were performed in individuals with early-stage PCA (N=5), amnestic AD dementia (N=22), and CN controls (N=47). Average tau and β-amyloid deposition were quantified using standard uptake value ratios and compared at a voxelwise level, controlling for age. PCA patients [median age-at-onset, 59 (51 to 61) years] were younger at symptom onset than similarly staged individuals with amnestic AD [75 (60 to 85) years] or CN controls [73 (61 to 90) years; P=0.002]. Flortaucipir uptake was higher in individuals with early-stage symptomatic PCA versus those with early-stage amnestic AD or CN controls, and greatest in posterior regions. Regional elevations in florbetapir were observed in areas of greatest tau deposition in PCA patients. Flortaucipir uptake distinguished individuals with PCA and amnestic AD dementia early in the symptomatic course. The posterior brain regions appear to be uniquely vulnerable to tau deposition in PCA, aligning with clinical deficits that define this disease subtype.

    Objective: To compare the accuracy of 99 Tc m -diethylene triamine pentaacetic acid ( 99 Tc m -DTPA) renal dynamic imaging and modified modification of diet in renal disease trail (MDRD) equation in determining the stage of the chronic kidney disease (CKD) patients in clinical practice. Methods: A total of 169 patients were enrolled whose glomerular filtration rate (GFR) were determined simultaneously by 3 methods: dual plasma sample clearance method, renal dynamic imaging and modified MDRD equation. The dual plasma sample clearance method was employed as the reference method. The accuracy of the other methods in determining the stage of CKD patients was compared and the comparison was repeated based on the different stages. Results: The accuracy of renal dynamic imaging and modified MDRD equation was 56.80% and 68.64%, respectively (P=0.019<0.05). And only in the stage of uremia, the difference of the above-mentioned two method reached statistical significance (P=0.012<0.05), while in other stages they showed similar performance (P=0.180, 0.424, 0.629 and 0.754, all P>0.05). Conclusion: Modified MDRD equation showed better performance than renal dynamic imaging or as good as the second one in determining the stage of CKD patients and the former one should be the first choice in clinical practice because of its simplicity and economy.

    To compare the difference in clinical efficacy on chronic obstructive pulmonary disease (COPD) at stable stage in the patients among the combined therapy of cutting method and western medication (combined therapy), simple cutting method and simple western medication. One hundred and twenty cases of COPD were randomized into three groups, 40 cases in each one. In the cutting method group, for excessive phlegm pattern/syndrome, Feishu (BL 13), Danzhong (CV 17), Dingchuan (EX-B 1) and Yuji (LU 10) were selected as the main acupoints, and Lieque (LU 7) and Pianli (LI 6) were as the supplementary acupoints. For the pattern/syndrome of failure to consolidate kidney primary, Shenshu (BL 23), Pishu (BL 20), Guanyuan (CV 4) and Yuji (LU 10) were selected as main acupoints, and Jueyinshu (BL 14) and Zusanli (ST 36) were as the supplementary acupoint. Three acupoints were selected alternatively in each treatment and the cutting method was applied once every 10 days. Three treatments made one session. Two sessions of treatment were required. In the western medication group, salbutamol sulfate aerosol, one press (200 μg/press) was used each night, as well as salmeterol xinafoate and fluticasone propionate powder for inhalation, one inhalation each night. The treatment of 1 month made one session. Two sessions were required. In the combined therapy group, the cutting method and western medication were applied in combination. The results of clinical symptom score, lung function test, arterial blood gas analysis, degree of inflation as well as clinical efficacy were observed before and after treatment in each group. Except the degree of lung inflation, the clinical symptom score, indices of lung function test, partial pressure of arterial blood gas (PaO2) and partial pressure of carbon dioxide (PaCO2) were all obviously improved after treatment as compared with those before treatment in each group (all Psyndrome differentiation and the combined therapy with western medication

  7. A combined pulmonary function and emphysema score prognostic index for staging in Chronic Obstructive Pulmonary Disease.

    Full Text Available Chronic Obstructive Pulmonary Disease (COPD is characterized by high morbidity and mortality. Lung computed tomography parameters, individually or as part of a composite index, may provide more prognostic information than pulmonary function tests alone.To investigate the prognostic value of emphysema score and pulmonary artery measurements compared with lung function parameters in COPD and construct a prognostic index using a contingent staging approach.Predictors of mortality were assessed in COPD outpatients whose lung computed tomography, spirometry, lung volumes and gas transfer data were collected prospectively in a clinical database. Univariate and multivariate Cox proportional hazard analysis models with bootstrap techniques were used.169 patients were included (59.8% male, 61.1 years old; Forced Expiratory Volume in 1 second % predicted: 40.5±19.2. 20.1% died; mean survival was 115.4 months. Age (HR = 1.098, 95% Cl = 1.04-1.252 and emphysema score (HR = 1.034, 95% CI = 1.007-1.07 were the only independent predictors of mortality. Pulmonary artery dimensions were not associated with survival. An emphysema score of 55% was chosen as the optimal threshold and 30% and 65% as suboptimals. Where emphysema score was between 30% and 65% (intermediate risk the optimal lung volume threshold, a functional residual capacity of 210% predicted, was applied. This contingent staging approach separated patients with an intermediate risk based on emphysema score alone into high risk (Functional Residual Capacity ≥210% predicted or low risk (Functional Residual Capacity <210% predicted. This approach was more discriminatory for survival (HR = 3.123; 95% CI = 1.094-10.412 than either individual component alone.Although to an extent limited by the small sample size, this preliminary study indicates that the composite Emphysema score-Functional Residual Capacity index might provide a better separation of high and low risk patients

    Full Text Available Persons with early-stage Parkinson’s disease (EPD do not typically experience marked functional deficits but may have difficulty with turning tasks. Studies evaluating turning have focused on individuals in advanced stages of the disease. The purpose of this study was to compare postural control strategies adopted during turning in persons with EPD to those used by healthy control (HC subjects. Fifteen persons with EPD, diagnosed within 3 years, and 10 HC participated. Participants walked 4 meters and then turned 90°. Dynamic postural control was quantified as the distance between the center of pressure (COP and the extrapolated center of mass (eCOM. Individuals with EPD demonstrated significantly shorter COP-eCOM distances compared to HC. These findings suggest that dynamic postural control during turning is altered even in the early stages of PD.

    Alzheimer's disease (AD) is a major neurodegenerative disease and the most common cause of dementia. Currently, no treatment exists to slow down or stop the progression of AD. There is converging belief that disease-modifying treatments should focus on early stages of the disease, that is, the mild cognitive impairment (MCI) and preclinical stages. Making a diagnosis of AD and offering a prognosis (likelihood of converting to AD) at these early stages are challenging tasks but possible with the help of multimodality imaging, such as magnetic resonance imaging (MRI), fluorodeoxyglucose (FDG)-positron emission topography (PET), amyloid-PET, and recently introduced tau-PET, which provides different but complementary information. This article is a focused review of existing research in the recent decade that used statistical machine learning and artificial intelligence methods to perform quantitative analysis of multimodality image data for diagnosis and prognosis of AD at the MCI or preclinical stages. We review the existing work in 3 subareas: diagnosis, prognosis, and methods for handling modality-wise missing data-a commonly encountered problem when using multimodality imaging for prediction or classification. Factors contributing to missing data include lack of imaging equipment, cost, difficulty of obtaining patient consent, and patient drop-off (in longitudinal studies). Finally, we summarize our major findings and provide some recommendations for potential future research directions. Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available Alzheimer’s disease (AD is characterized by disorders that can impair the nutrition of the patient and lead to weight loss and nutritional deficits during the course of the disease. The aim of this study was to assess the nutritional status and food intake of Brazilian patients with Alzheimer’s disease at 3 different stages of the disease. The sample consisted of 30 subjects of both genders, mean age 77 years, with probable AD. Subjects were assessed by collecting anthropometric data, the Mini Nutritional Assessment (MNA, serum albumin content, Mini Mental State Examination and 24-hour records of food and drink. Although a steady decrease in average weight was observed as the disease progressed (CDR1: 70.8±15.9 kg; CDR2: 61.4±15.7 kg; CDR3: 56.1± 8.4 kg, the differences were not significant. MNA and serum albumin both fell during the progression of the disease (p = 0.042; p = 0.047, respectively and, at the severe stage, half the patients were found to be undernourished and the other half at risk of undernutrition. According to their body mass index, 23.3% of patients were overweight. The nutritional value of the food consumed was similar across the stages of AD. In conclusion, the majority of Brazilian patients with AD in this study exhibited cognitive decline and malnutrition. However, food intake was similar among the stages of the disease, thus having no direct association with the progression of AD.

    The Latin American Dialysis and Renal Transplant Registry (RLADTR) was founded in 1991; it collects data from 20 countries which are members of Sociedad Latinoamericana de Nefrología e Hipertension. This paper presents the results corresponding to the year 2010. This study is an annual survey requesting data on incident and prevalent patients undergoing renal replacement treatment (RRT) in all modalities: hemodialysis (HD), peritoneal dialysis (PD) and living with a functioning graft (LFG), etc. Prevalence and incidence were compared with previous years. The type of renal replacement therapy was analyzed, with special emphasis on PD and transplant (Tx). These variables were correlated with the gross national income (GNI) and the life expectancy at birth. Twenty countries participed in the surveys, covering 99% of the Latin American. The prevalence of end stage renal disease (ESRD) under RRT in Latin America (LA) increased from 119 patients per million population (pmp) in 1991 to 660 pmp in 2010 (HD 413 pmp, PD 135 pmp and LFG 111 pmp). HD proportionally increased more than PD, and Tx HD continues to be the treatment of choice in the region (75%). The kidney Tx rate increased from 3.7 pmp in 1987 to 6.9 pmp in 1991 and to 19.1 in 2010. The total number of Tx's in 2010 was 10 397, with 58% deceased donors. The total RRT prevalence correlated positively with GNI ( r 2 0.86; P chronic kidney disease (CKD) and its associated risk factors. PD is still an underutilized strategy for RRT in the region. Even though renal Tx is feasible, its growth rate is still not as fast as it should be in order to compensate for the increased prevalence of patients on waiting lists. Diagnostic and prevention programs for hypertension and diabetes, appropriate policies promoting the expansion of PD and organ procurement as well as transplantation as cost-effective forms of RRT are needed in the region. Regional cooperation among Latin American countries, allowing the more developed to

    To determine skin changes in patients of End Stage Renal Disease (ESRD) on maintenance hemodialysis (MHD) and factors affecting these changes. Study Design:Cross-sectional observational study. Place and Duration of Study:Nephrology Department, Mayo Hospital, Lahore in collaboration with Dermatology Department, King Edward Medical University, Lahore, from October 2015 to January 2016. Methodology:Two hundred patients who were undergoing MHD for more than three months were included in the study. Patients' demographic data, laboratory reports and dialysis records were noted in a predesigned questionnaire. Skin examination was carried out by consultant dermatologist after patient's permission. Results:Among 200 patients included in study, 105 were males and rest of them were females. Major causes of ESRD were Diabetes Mellitus (n=83, 41.5%, followed by Hypertension (n=80, 40%), Nephrolithiasis (n=15, 7.5%) and Chronic glomerulonephritis (n=5, 2.5%). At least one cutaneous finding was present in every patient. Common skin findings observed were pigmentation (86%), xerosis (83%), pallor (79%), pruritus (69%), acquired ichthyosis (50.5%), and bacterial skin infections (18.5%). Among them, nail manifestations were half-and-half nails (52%), nychomycosis (30.5%), onycholysis (20.5%), subungual hyperkeratosis (23.5%), and Mee's lines (7.5). Among hair changes were sparse scalp hair (38.5%), brittle and lustreless hair (28%). The factors contributing to skin changes were patient's age, cause of ESRD, anti HCV positivity, high urea and creatinine levels, duration and frequency of hemodialysis, hemoglobin levels, calcium phosphate product and socioeconomic status. Some skin manifestations were interrelated with each other like xerosis with pruritus (p<0.001), pruritus with bacterial infection (p<0.022), acquired Ichthyosis (p=0.008) and hair changes (p=0.035). Conclusion:ESRD patients on hemodialysis develop various skin changes during the course of disease

    Full Text Available Abstract Background The question of a genetic contribution to the higher prevalence and incidence of end stage kidney disease (ESKD among African Americans (AA remained unresolved, until recent findings using admixture mapping pointed to the association of a genomic locus on chromosome 22 with this disease phenotype. In the current study we utilize this example to demonstrate the utility of applying a multi-step admixture mapping approach. Methods A multi-step case only admixture mapping study, consisted of the following steps was designed: 1 Assembly of the sample dataset (ESKD AA; 2 Design of the estimated mutual information ancestry informative markers (n = 2016 screening panel 3; Genotyping the sample set whose size was determined by a power analysis (n = 576 appropriate for the initial screening panel; 4 Inference of local ancestry for each individual and identification of regions with increased AA ancestry using two different ancestry inference statistical approaches; 5 Enrichment of the initial screening panel; 6 Power analysis of the enriched panel 7 Genotyping of additional samples. 8 Re-analysis of the genotyping results to identify a genetic risk locus. Results The initial screening phase yielded a significant peak using the ADMIXMAP ancestry inference program applying case only statistics. Subgroup analysis of 299 ESKD patients with no history of diabetes yielded peaks using both the ANCESTRYMAP and ADMIXMAP ancestry inference programs. The significant peak was found on chromosome 22. Genotyping of additional ancestry informative markers on chromosome 22 that took into account linkage disequilibrium in the ancestral populations, and the addition of samples increased the statistical significance of the finding. Conclusions A multi-step admixture mapping analysis of AA ESKD patients replicated the finding of a candidate risk locus on chromosome 22, contributing to the heightened susceptibility of African Americans to develop non

    Cardiovascular morbidity and mortality are common in end stage renal disease (ESRD) patients. There is scarce data on carotid and bulb intima-media thickness (IMT-C and IMT-B) as an early marker of atherosclerosis and related factors in children on hemodialysis (HD) and peritoneal dialysis (PD). Since we did not have enough information about our patients, this study was carried on all ESRD children (hemodialysis and peritoneal dialysis) in a referral center. Data was collected from 16 ESRD children under 18 years with seven patients on PD and nine on HD. Lab tests and biochemical parameters including serum von Willebrand factor (vWF), homocystein, apo lipoprotein A, apo lipoprotein B and quantitative CRP were measured in fasting patients just before initiating dialysis. IMT-C and IMT-B were measured by gray scale ultrasound using 7.5 MHZ probe. The mean of age was 12.76+/-4.5 years. The mean duration of dialysis in HD and PD patients were not significantly different; 11.88+/-3.25 months and 10.14+/-2.4 months respectively. Mean of systolic blood pressure in HD group was significantly higher than PD group, 135.55+/-25.54 mmHg versus 121.42+/-12.14 mmHg, Phomocystein and IMT-C. However, we could not demonstrate any difference between IMT-B in case and control group. After adjusting for age, partial correlation showed significant correlation between IMT-C and following factors: N-PTH and serum alkaline phosphatase. Longitudinal studies with large size samples are needed to clarify the contributing factors with intima-media thickness in ESRD children.

    Summary Objective Hyperphosphatemia is common in end-stage renal disease (ESRD), and associates with mortality. Phosphate binders reduce serum phosphorus; however, adherence is often poor. This pilot study aims to assess patients’ self-motivation to adhere to phosphate binders, its association with phosphorus control, and potential differences by race. Design Cross-sectional Participants and measurements Subjects were enrolled from one academic medical center dialysis practice from July–November 2012. Self-motivation to adhere to phosphate binders was assessed with the Autonomous Regulation (AR) scale (range: 1–7), and self-reported medication adherence with the Morisky Medication Adherence Scale (MMAS). Linear regression models adjusting for age, gender, health literacy and medication adherence were applied to determine associations with serum phosphorus level, including any evidence of interaction by race. Results Among 100 participants, mean age was 51 years (± 15), 53% were male, 72% were non-white, 89% received hemodialysis, and mean serum phosphorus level was 5.7 [±1.6] mg/dL. More than half (57%) reported the maximum AR score (7). Higher AR scores were noted in those reporting better health overall (p=0.001) and those with higher health literacy (p=0.01). AR score correlated with better medication adherence (r=0.22; p=0.02), and medication adherence was negatively associated with serum phosphorus (r= −0.40; pSelf-motivation was associated with phosphate binder adherence and phosphorus control, and this differed by race. Additional research is needed to determine if personalized, culturally sensitive strategies to understand and overcome motivational barriers may optimize mineral bone health in ESRD. PMID:25912398

    Obesity is a relative contraindication to organ transplantation. Preliminary reports suggest that bariatric surgery may be used as a bridge to transplantation in patients who are not eligible for transplantation because of morbid obesity. The Bariatric Center at Tampa General Hospital, University of South Florida, Tampa, Florida. We reviewed the outcomes of 16 consecutive patients on hemodialysis for end-stage renal disease (ESRD) who underwent bariatric surgery from 1998 to 2016. Demographics, comorbidities, weight loss, as well as transplant status were reported. Data is mean ± SD. Six men and ten women aged 43-66 years (median = 54 years) underwent laparoscopic Roux-en-Y gastric bypass (LRYGB, n = 12), laparoscopic adjustable gastric banding (LAGB, n = 3), or laparoscopic sleeve gastrectomy (LSG, n = 1). Preoperative BMI was 48 ± 8 kg/m 2 . Follow-up to date was 1-10 years (median = 2.8 years); postoperative BMI was 31 ± 7 kg/m 2 ; %EBWL was 62 ± 24. Four patients underwent renal transplantation (25%) between 2.5-5 years after bariatric surgery. Five patients are currently listed for transplantation. Five patients were not listed for transplantation due to persistent comorbidities; two of these patients died as a consequence of their comorbidities (12.5%) more than 1 year after bariatric surgery. Two patients were lost to follow-up (12.5%). Bariatric surgery is effective in patients with ESRD and improves access to renal transplantation. Bariatric surgery offers a safe approach to weight loss and improvement in comorbidities in the majority of patients. Referrals of transplant candidates with obesity for bariatric surgery should be considered early in the course of ESRD.

    Full Text Available The study focuses on the mechanisms of endothelial dysfunction in the uremic milieu. Subcutaneous resistance arteries from 35 end-stage renal disease (ESRD patients and 28 matched controls were studied ex-vivo. Basal and receptor-dependent effects of endothelium-derived factors, expression of endothelial NO synthase (eNOS, prerequisites for myoendothelial gap junctions (MEGJ, and associations between endothelium-dependent responses and plasma levels of endothelial dysfunction markers were assessed. The contribution of endothelium-derived hyperpolarizing factor (EDHF to endothelium-dependent relaxation was impaired in uremic arteries after stimulation with bradykinin, but not acetylcholine, reflecting the agonist-specific differences. Diminished vasodilator influences of the endothelium on basal tone and enhanced plasma levels of asymmetrical dimethyl L-arginine (ADMA suggest impairment in NO-mediated regulation of uremic arteries. eNOS expression and contribution of MEGJs to EDHF type responses were unaltered. Plasma levels of ADMA were negatively associated with endothelium-dependent responses in uremic arteries. Preserved responses of smooth muscle to pinacidil and NO-donor indicate alterations within the endothelium and tolerance of vasodilator mechanisms to the uremic retention products at the level of smooth muscle. We conclude that both EDHF and NO pathways that control resistance artery tone are impaired in the uremic milieu. For the first time, we validate the alterations in EDHF type responses linked to kinin receptors in ESRD patients. The association between plasma ADMA concentrations and endothelial function in uremic resistance vasculature may have diagnostic and future therapeutic implications.

    Full Text Available Background : Many patients with end-stage renal disease (ESRD undergoing hemodialysis (HD experience depression. Depression influences patient quality of life (QOL, dialysis compliance, and medical comorbidity. We developed and applied a group cognitive behavioral therapy (CBT program including mindfulness meditation for ESRD patients undergoing HD, and measured changes in QOL, mood, anxiety, perceived stress, and biochemical markers. Methods : We conducted group CBT over a 12-week period with seven ESRD patients undergoing HD and suffering from depression. QOL, mood, anxiety, and perceived stress were measured at baseline and at weeks 8 and 12 using the World Health Organization Quality of Life scale, abbreviated version (WHOQOL-BREF, the Beck Depression Inventory II (BDI-II, the Hamilton Rating Scale for Depression (HAM-D, the Beck Anxiety Inventory (BAI, and the Perceived Stress Scale (PSS. Biochemical markers were measured at baseline and after 12 weeks. The Temperament and Character Inventory was performed to assess patient characteristics before starting group CBT. Results : The seven patients showed significant improvement in QOL, mood, anxiety, and perceived stress after 12 weeks of group CBT. WHOQOL-BREF and the self-rating scales, BDI-II and BAI, showed continuous improvement across the 12-week period. HAM-D scores showed significant improvement by week 8; PSS showed significant improvement after week 8. Serum creatinine levels also improved significantly following the 12 week period. Conclusion : In this pilot study, a CBT program which included mindfulness meditation enhanced overall mental health and biochemical marker levels in ESRD patients undergoing HD.

    In a collaborative effort between the Missouri Department of Health, Area Agencies on Aging (AAA), Alzheimer Association, and academic researchers, we tested whether early dementia detection and comprehensive care consultations would improve health outcomes in care receivers (CRs) and their family caregivers (FCGs), therefore addressing an important public health concern. A total of 244 community-dwelling older adults screened for early-stage dementia by the AAA field staff were referred to the Alzheimer Association and participated in Project Learn MORE (Missouri Outreach and Referral Expanded) (PLM) - a 2-year, nonrandomized multisite intervention consisting of comprehensive care consultations to improve coping skills. PLM participants were compared against 96 controls receiving the Alzheimer Association's "usual services" between January 2011 and December 2012. We examined CR and FCG outcomes, including burden, care confidence, and mood, as effects of PLM, on delaying transitions in level of care. CRs showed improved knowledge (P=0.002) and reduced depression (P=0.007), while FCGs demonstrated improved knowledge (P=0.003) and ability to identify sources of support for the CR (P=0.032) and for themselves (P=0.043). However, FCGs were more burdened after PLM (P=0.02), due to increased awareness of Alzheimer's disease. PLM delayed transitions in care (odds ratio [OR] 3.32, 95% confidence level [CI]: 1.25-8.83) with the number needed to treat =6.82. PLM was successful in improving detection of incident cases of dementia in the community and in connecting patients and their families with needed services. Our findings support the use of state agencies and community service partners to detect dementia. Early implementation of psychosocial interventions could have significant impact in improving patient- and family-centered outcomes, potentially providing a cost-efficient alternative to pharmacotherapy.

    Denosumab, a RANK-ligand inhibitor, is an effective treatment for osteoporosis in postmenopausal women and men. Unlike the bisphosphonates, it is not excreted by the kidney. Little is known, however, about its efficacy and safety in patients with severe chronic kidney disease (CKD). A retrospective study was performed in CKD 4-5D patients from a tertiary referral hospital who were treated with denosumab between 1st January 2011 and 31st March 2014. Data collected included information about the following: CKD stage, fracture history, bone mineral density, serum calcium levels pre and post denosumab treatment, episodes of hypocalcemia, relevant medications and adverse events. Eight patients with CKD-5 and 6 patients with CKD-4 were identified (all female, mean age 77.1 ± 9.9). The mean pre-denosumab calcium value was 2.42 ± 0.12 mmol/l, PTH 20.2 ± 14.7 pmol/l and 25-OH vitamin D 69.1 ± 30.1 nmol/l. After denosumab treatment, 6/8 patients with CKD-5/5D, and 2/5 patients with CKD-4 developed severe hypocalcemia. Two patients developed direct adverse complications of hypocalcemia (seizure, laryngospasm, prolonged QTc). Among the patients who developed hypocalcemia, the median time to serum calcium nadir was 21 days and the median time to correction of hypocalcemia was 71 days. Treatment of hypocalcemia required large doses of oral calcium and calcitriol, and increases in dialysate calcium concentration. A high rate of severe hypocalcemia was observed in patients with advanced CKD treated with denosumab. If denosumab is used in patients with severe CKD, close monitoring and aggressive replacement of calcium and calcitriol is required to avoid the development of hypocalcemia.

    Patients with end stage renal diseases (ESRD) undergoing hemodialysis (HD) have high morbidity and mortality due to multiple causes; one of which is dramatically higher fall rates than the general population. In spite of the multiple efforts aiming to decrease the high mortality and improve quality of life in ESRD patients, limited success has been achieved. If adequate interventions for fall prevention are to be achieved, the functional and mobility mechanisms consistent with falls in this population must be understood. Human movements such as sit-to-walk (STW) tasks are clinically significant, and analysis of these movements provides a meaningful evaluation of postural and locomotor performance in elderly patients with functional limitations indicative of fall risks. In order to assess the effects of HD therapy on fall risks, 22 sessions of both pre- and post-HD measurements were obtained in six ESRD patients utilizing customized inertial measurement units (IMU). IMU signals were denoised using ensemble empirical mode decomposition and Savistky-Golay filtering methods to detect relevant events for identification of STW phases. The results indicated that patients were slower to get out of the chair (as measured by trunk flexion angular accelerations, time to peak trunk flexion, and overall STW completion time) following the dialysis therapy session. STW is a frequent movement in activities of daily living, and HD therapy may influence the postural and locomotor control of these movements. The analysis of STW movement may assist in not only assessing a patient's physical status, but in identifying HD-related fall risk as well. This preliminary study presents a non-invasive method of kinematic measurement for early detection of increased fall risk in ESRD patients using portable inertial sensors for out-patient monitoring. This can be helpful in understanding the pathogenesis better, and improve awareness in health care providers in targeting interventions to
