    Purpose: Endothelial-like vascular progenitor cells (VPCs) are associated with the repair of ischemic tissue injury in several clinical settings. Because the endothelium is a principal target of radiation injury, VPCs may be important in limiting toxicity associated with radiotherapy (RT) in patients with cancer. Methods and Materials: We studied 30 patients undergoing RT for skin cancer (n = 5), head-and-neck cancer (n = 15), and prostate cancer (n = 10) prospectively, representing a wide range of irradiated mucosal volumes. Vascular progenitor cell levels were enumerated from peripheral blood at baseline, midway through RT, at the end of treatment, and 4 weeks after radiation. Acute toxicity was graded at each time point by use of the National Cancer Institute's Common Toxicity Criteria, version 3.0. Results: Significant increases in the proportion of CD34 + /CD133 + VPCs were observed after completion of RT, from 0.012% at baseline to 0.048% (p = 0.029), and the increase in this subpopulation was most marked in patients with Grade 2 peak toxicity or greater after RT (p = 0.034). Similarly, CD34 + /vascular endothelial growth factor receptor 2-positive VPCs were increased after the completion of radiation therapy in comparison to baseline (from 0.014% to 0.027%, p = 0.043), and there was a trend toward greater mobilization in patients with more significant toxicity (p = 0.08). The mobilization of CD34 + hematopoietic stem cells did not increase after treatment (p = 0.58), and there was no relationship with toxicity. Conclusions: We suggest that VPCs may play an important role in reducing radiation-induced tissue damage. Interventions that increase baseline VPC levels or enhance their mobilization and recruitment in response to RT may prove useful in facilitating more rapid and complete tissue healing.

    Hypothyroidism is a common adverse effect of vascular endothelial growth factor receptor tyrosine kinase inhibitor (VEGFR-TKI) therapy in patients with metastatic renal cell carcinoma (mRCC). Some studies have shown an association with improved survival. However, hypothyroidism severity has not been correlated with survival outcomes. We report the incidence and severity of VEGFR-TKI therapy-associated hypothyroidism in correlation with the survival outcomes of patients with mRCC. A retrospective analysis of patients with mRCC who received VEGFR-TKIs (2004 through 2013) was conducted from a single institutional database. Hypothyroidism, progression-free survival (PFS), and overall survival (OS) were assessed. Univariate and multivariate analyses were performed using the Kaplan-Meier method and Cox proportional hazard models. Of 125 patients with mRCC, 65 were eligible. Their median age was 59 years (range, 45-79 years), and 46 (70.8%) were male. Hypothyroidism occurred in 25 patients (38.5%), of whom 13 had a peak thyroid-stimulating hormone (TSH) level > 10 mIU/L during treatment. The median OS was significantly longer in patients with a peak TSH > 10 mIU/L than in patients with a peak TSH of ≤ 10 mIU/L (not reached vs. 21.4 months, P = .005). On multivariate analysis, risk criteria, number of previous therapies, and severe hypothyroidism (TSH > 10 mIU/L) during VEGFR-TKI therapy remained significant for improvements in PFS and OS. The severity of VEGFR-TKI therapy-associated hypothyroidism (TSH > 10 mIU/L) was associated with improved survival outcomes in patients with mRCC and should not necessitate a dose reduction or therapy discontinuation.

    To describe hypersensitivity reactions in patients receiving maintenance hemodialysis. PubMed search of articles published during the past 30 years with an emphasis on publications in the past decade. Case reports and review articles describing hypersensitivity reactions in the context of hemodialysis. Pharmacologic agents are the most common identifiable cause of hypersensitivity reactions in patients receiving hemodialysis. These include iron, erythropoietin, and heparin, which can cause anaphylactic or pseudoallergic reactions, and topical antibiotics and anesthetics, which lead to delayed-type hypersensitivity reactions. Many hypersensitivity reactions are triggered by complement activation and increased bradykinin resulting from contact system activation, especially in the context of angiotensin-converting enzyme inhibitor use. Several alternative pharmacologic preparations and dialyzer membranes are available, such that once an etiology for the reaction is established, recurrences can be prevented without affecting the quality of care provided to patients. Although hypersensitivity reactions are uncommon in patients receiving hemodialysis, they can be life-threatening. Moreover, considering the large prevalence of the end-stage renal disease population, the implications of such reactions are enormous. Most reactions are pseudoallergic and not mediated by immunoglobulin E. The multiplicity of potential exposures and the complexity of the environment to which patients on dialysis are exposed make it challenging to identify the precise cause of these reactions. Great diligence is needed to investigate hypersensitivity reactions to avoid recurrence in this high-risk population. Copyright © 2017 American College of Allergy, Asthma & Immunology.

    Full Text Available Thorsten Reffelmann, Robert A KlonerUniversity of Southern California, The Heart Institute, Good Samaritan Hospital, Division of Cardiovascular Medicine, Keck School of Medicine, Los Angeles, CA, USAAbstract: In many forms of erectile dysfunction (ED, cardiovascular risk factors, in particular arterial hypertension, seem to be extremely common. While causes for ED are related to a broad spectrum of diseases, a generalized vascular process seems to be the underlying mechanism in many patients, which in a large portion of clinical cases involves endothelial dysfunction, ie, inadequate vasodilation in response to endothelium-dependent stimuli, both in the systemic vasculature and the penile arteries. Due to this close association of cardiovascular disease and ED, patients with ED should be evaluated as to whether they may suffer from cardiovascular risk factors including hypertension, cardiovascular disease or silent myocardial ischemia. On the other hand, cardiovascular patients, seeking treatment of ED, must be evaluated in order to decide whether treatment of ED or sexual activity can be recommended without significantly increased cardiac risk. The guideline from the first and second Princeton Consensus Conference may be applied in this context. While consequent treatment of cardiovascular risk factors should be accomplished in these patients, many antihypertensive drugs may worsen sexual function as a drug specific side-effect. Importantly, effective treatment for arterial hypertension should not be discontinued as hypertension itself may contribute to altered sexual functioning; to the contrary, alternative antihypertensive regimes should be administered with individually tailored drug regimes with minimal side-effects on sexual function. When phosphodiesterase-5 inhibitors, such as sildenafil, tadalafil and vardenafil, are prescribed to hypertensive patients on antihypertensive drugs, these combinations of antihypertensive drugs and

    Full Text Available Abstract Introduction Bevacizumab is a monoclonal antibody that inhibits the action of vascular endothelial growth factor (VEGF thereby acting as an angiogenesis inhibitor. As a result, supply of oxygen and nutrients to tissues is impaired and tumour cell growth is reduced. Reported side effects due to bevacizumab are hypertension and increased risk of bleeding. Bowel perforation has also been reported. Periodontal disease in patients on bevacizumab therapy has not been reported before. Case Presentation We report a case of a forty-three year old woman who developed periodontitis whilst receiving bevacizumab for lung cancer. The periodontal disease remained stable on discontinuation of the drug. Conclusion Further investigations are needed to determine the mechanism for bevacizumab-induced periodontal disease.

    Full Text Available Introduction: Vascular and valvular calcifications are a frequent complication in dialyzed patients and are connected to an increased morbi-mortality. Many radiological methods (TAC multiple slices and with electrons emission have been used to investigate the presence of vascular calcifications in this population, but only few works have been focused on simple radiology. Objectives: The objectives of this work are to evaluate vascular calcifications by means of Kauppila index in hemodialysis prevalent patients, identify linked risk factors and determine their association with heart valves calcification. Methods: 95 stable patients under hemodialysis were surveyed during a period of 6 months longer. Abdominal Rx simple profile were performed on all patients to evaluate calcification of abdominal aorta by Kauppila index and twodimensional echocardiogram to detect valvular calcifications. Data were collected about sex, age, diabetes, Hypertension, tabaquism, dislipemia and bone-mineral metabolism. Results: 64.5% of the patients showed vascular calcifications. Average Kauppila index was 6.25. Age and time on dialysis correlated with vascular calcifications. In 31.6 % of individuals valvular calcifications were found, which presented significant association with diabetes and Kauppila Index. Conclusions: Vascular and valvular calcifications were frequent in the surveyed population. Kauppila index correlated with age, time on dialysis and valvular calcifications. Heart valves calcification was associated with diabetes.

  15. Every second cancer patient receives radiotherapy

    Radiotherapy to treat cancer was given for the first time exactly one hundred years ago. Today, radiotherapy and surgery are the two main modes of treating cancer. One in two cancer patients receives radiotherapy at some point during the course of treatment for the disease. Radiotherapy is applied most commonly in cases where surgery is not possible. Moreover, these two modes of treatment are often used together to supplement each other. About half of new cancer cases detected today can be ordered. The estimate given by the EU for cancers cured is 45 per cent, which is divided between the various treatment modes as follows: surgery 22 %, radiotherapy 12 %, surgery plus radiotherapy 6 %, and drug therapy 6 %. In addition to curative treatment, radiotherapy plays a crucial role in palliative treatment, i.e. treatment that alleviates symptoms. The sensitivity of malignant tumours to radiotherapy varies over a wide range; the same is true for healthy tissues. Radiotherapy can only be used to cure a tumour that is more sensitive to radiation than the surrounding healthy tissue. The tumour must also be sufficiently small in size and limited to a relatively small area. (orig.)

    Peritonitis on catheter of dialysis represents the most frequent complication of the peritoneal dialysis (PD) in the pediatric population. It remains a significant cause of morbidity and mortality. In this study, we investigated the risk factors for peritonitis in children. In this study, we retrospectively collected the records of 85 patients who were treated with PD within the past ten years in the service of pediatrics of the University Hospital Charles-Nicolle of Tunis. Peritonitis rate was 0.75 episode per patient-year. Notably, peritonitis caused by Gram-positive organisms were more common. Analysis of infection risk revealed three significant independent factors: the poor weight (P=0.0045), the non-automated PD (P=0.02) and the short delay from catheter insertion to starting PD (P=0.02). The early onset peritonitis was significantly associated with frequent peritonitis episodes (P=0.0008). The mean duration between the first and second episode of peritonitis was significantly shorter than between PD commencement and the first episode of peritonitis. We revealed a significant association between Gram-negative peritonitis and the presence of ureterostomy (0.018) and between Gram-positive peritonitis and the presence of exit-site and tunnel infections (0.02). Transition to permanent hemodialysis was needed in many children but no death occurred in patients with peritonitis. Considering the important incidence of peritonitis in our patients, it is imperative to establish a targeted primary prevention. Nutritional care must be provided to children to avoid poor weight. The automated dialysis has to be the modality of choice. Copyright © 2015 Association Société de néphrologie. Published by Elsevier SAS. All rights reserved.

    To find out the frequency of Alzheimer's and Vascular dementia in the elderly patients. This cross sectional descriptive study was conducted in Department of Medicine, Ziauddin Hospital Karachi from 1 st October 2013 to 31 st March 2014. Patients with symptoms of dementia for more than 6 months duration, and Mini Mental State Examination score dementia were assessed for duration of symptoms. Patients underwent CT scan of brain. Patients with generalized atrophy of brain on CT scanning of brain were labeled as Alzheimer's dementia, while patients with ischemic or hemorrhagic stroke on CT scan of brain were labeled as vascular dementia. Four hundred twenty two patients were included in this study. There were 232 (54.98 %) male and 190 (45.02 %) were female. The mean age ± SD of the patients was 72.58±5.34 years (95% CI: 72.07 to 73.09), similarly average duration of symptoms was 10.14±2.85 months. About 18.96% of patients were illiterate, 32.23% were matric, 28.44% were intermediate and 20.33% were graduate and post graduate. Hypertension and diabetes were the commonest co-morbid i.e. 81.3% and 73.7%, hyperlipedimia and smoking were 38.2% and 45% respectively. Frequency of Alzheimer's disease and vascular dementia in the elderly was observed in 3.79% (16/422) and 2.61% (11/422) cases. A good number of patients, 27 out of 422, in this hospital based study were suffering from Alzheimer's disease and vascular dementia. Early detection and prompt treatment can reduce the burden of the disease in our population.

    Full Text Available Abstract Background The structure of health care in Greece is receiving increased attention to improve its cost-effectiveness. We sought to examine the epidemiological characteristics of patients presenting to the vascular emergency department of a Greek tertiary care hospital during a 2-year period. We studied all patients presenting to the emergency department of vascular surgery at Red Cross Hospital, Athens, Greece between 1st January 2009 and 31st December 2010. Results Overall, 2452 (49.4% out of 4961 patients suffered from pathologies that should have been treated in primary health care. Only 2509 (50.6% needed vascular surgical intervention. Conclusions The emergency department of vascular surgery in a Greek tertiary care hospital has to treat a remarkably high percentage of patients suitable for the primary health care level. These results suggest that an improvement in the structure of health care is needed in Greece.

    In France, the Leonetti law, adopted on April 22, 2005, stipulates the regulations concerning advanced directives. This is a patient's right that is not well known and rarely applied. In 2015, a new law project was thus presented in which the French National Authority for Health recommended that doctors, including all specialists, bring up the subject, especially during consultation. To evaluate the vascular specialist's possibility to mention the topic of advanced directives during consultations. A single and non-interventional prospective study conducted with the help of patients who consulted a private practitioner vascular specialist: recurrent patients regularly consulting a private practitioner vascular specialist were included. First-time consultants, minors and patients to whom it was not adapted to speak about the subject were not included. Between July 27 and September 23, 2015, 159 consecutive patients were examined. Fifty-five first-time consultants and four patients for whom the interview was unsuitable were excluded. In all, 100 patients were questioned. None of them refused to talk about the subject. Women made up a majority of the population (63 %) with an average age of 67 years (23-97). The principal diagnostics were common to vascular medicine consultations: deep vein thrombosis (20 %), peripheral arterial disease (15 %), varicose veins (11 %), lymphedema (11 %) and leg ulcers (9 %). Thirteen percent of the people had a history of cancer. Half of the patients had had follow-ups for over 10 years. The average time devoted to discussing the topic was 12minutes (5-40). Only 22 % of the patients declared having been familiar with advance directives. Once informed however, 78 % chose to write up an adapted form: 36 % with the help of their doctor and 42 % with a doctor and a relative. Seventy-three percent of the consultants thought that talking about the advance directives would reinforce the confidence link between the doctor and the

    External radiation therapy, or teletherapy, is the use of ionizing radiation to destroy cancer cells. Clinical use of ionizing radiation as treatment for cancer began with the discovery of x-rays in 1895, the identification of natural radioactivity (radium) in 1896, and the first reported cure of cancer, a basal cell epithelioma, induced by radiation in 1899. Initially, radiation was administered as a single large dose and produced severe, life-threatening side effects. The basis for the use of ionizing radiation in daily increments for a period of weeks was provided by Regaud in 1922; ten years later, Coutard clinically developed the method of dose fractionation, which remains in use today. Although the use of ionizing radiation as a treatment is over eighty years old, only in recent years have advancements in its clinical application been based on research related to the biologic effect of radiation on human cells. To effectively care for the patient prior to, during, and at the completion of external radiation therapy, the nurse must know the physical and biologic basis of external radiation therapy and its clinical application.

    Vascular calcification is established to be a critical factor in diabetes mellitus, which causes cardiovascular and amputation complication of diabetic patients. OPG/RANKL/RANK axis serves as a regulatory role in vascular calcification. Ghrelin, an endogenous ligand of growth hormone secretagogue receptor (GHSR), has been reported to exhibit potent cardiovascular protective effects. However, the role of ghrelin in the regulation of diabetic vascular calcification is still elusive. Here, we reported the role of ghrelin and its relationship with OPG/RANKL/RANK system in patients with diabetic foot amputation. In vivo and in vitro investigations were performed. Sixty type 2 diabetic patients with foot amputation were enrolled in vivo investigation, and they were divided into three groups through Doppler ultrasound: mild stenosis group (n=20), moderate stenosis group (n=20), and severe stenosis/occlusion group (n=20). Morphological analysis results showed diffused calcium depositions in the anterior tibial artery of diabetic amputees. Compared with the mild and moderate stenosis group, the severe stenosis/occlusion group had more spotty calcium depositions in atherosclerotic plaques. Western blot analysis indicated the expressions of osteoprotegerin (OPG) and ghrelin were downregulated, while the expression of receptor activator of nuclear factor kappa B ligand (RANKL) was upregulated with the vascular stenosis aggravation. Pearson correlation analysis revealed a negative correlation between calcium content and ghrelin levels (r=-0.58, Pghrelin levels and sRANKL levels (r=-0.57, Pghrelin levels (r=0.63, PGhrelin blunted calcification in a dose-dependent manner. In addition, ghrelin upregulated OPG expression and downregulated RANKL expression in VSMC calcification when anti-OPG antibody and RANKL were performed. Collectively, we therefore conclude serum ghrelin level may be a predictor of diabetic vascular calcification. The possible mechanism may be related with OPG

    Full Text Available The outpatient records of 147 patients followed up for diagnosed vascular dementia were analyzed to assess the relationship between affective disorders and severe cognitive impairments. It was found that 7% of the examinees had a history of depressive states. Estimating the development time for vascular dementia could divide the patients into 2 groups: 1 60% of the patients in whom cognitive impairments began to determine its clinical picture just within the first 2 years after identification of affective disorders and 2 40%, in whom cognitive impairments occurred 10—20 years later. In both groups, mental disorders occurred at an equal age in the presence of depressive disorders; in Group 1, vascular dementia developed nearly twice as often as that in Group 2. At the same time, the occurrence of cognitive impairments in Group 1 patients just in the early disease stages is indicative of the organic genesis of affective disorders, as confirmed by the moderately rapid progression of psychopathological symptoms, such as sharpening of personality traits, increased rigidity of psychic processes, emotional lability, variations in affective symptomatology, inadequate remissions, and the presence of neurological symptoms. Another type of a ratio of depressive to severe cognitive disorders was found in the elderly persons in Group 2. The long existence of affective disorders without signs of cognitive diminution leads one to say that they have recurrent depressive disorder with further addition of a comorbid vascular process. These patients showed a fairly high severity of affective pathology that was responsible for more frequent admissions, as well as a phase course with relatively pure remissions without any clear intellectual-mnestic reduction and a predominance of hysterical character traits.

    In hemodynamically unstable patients, the management of retroperitoneal vascular trauma is both difficult and challenging. Endovascular techniques have become an alternative to surgery in several trauma centers. Between 2004 and 2006, 16 patients (nine men, mean age: 46 years, range: 19-79 years) with retroperitoneal vascular trauma and hemodynamic instability were treated using an endovascular approach. The mean injury severity score was 30.7 ± 13.1. Mean systolic blood pressure and the shock index were 74 mm Hg and 1.9, respectively. Vasopressor drugs were required in 68.7% of cases (n = 11). Injuries were attributable to road traffic accidents (n = 15) and falls (n = 1). The hemorrhage sites included the internal iliac artery or its branches (n = 12) with bilateral injury in one case, renal artery (n = 2), abdominal aorta (n = 1), and lumbar artery (n = 1). In all, 14 coil embolizations and three stent-grafts were implanted. The technical success rate was 75%, as early re-embolization was necessary in one case and three patients died during the perioperative period. Six patients died during the period of hospitalization (37.5%). No surgical conversion or major morbidity was reported. In comparison with particulates, coil ± stent-graft may provide similar efficacy with regard to survival, and thus may be a valuable solution when particulate embolization is not available or feasible.

    Hemodialysis vascular access recommendations promote arteriovenous (AV) fistulas first; however, it may not be the best approach for all hemodialysis patients, because likelihood of successful fistula placement, procedure-related and subsequent costs, and patient survival modify the optimal access choice. We performed a decision analysis evaluating AV fistula, AV graft, and central venous catheter (CVC) strategies for patients initiating hemodialysis with a CVC, a scenario occurring in over 70% of United States dialysis patients. A decision tree model was constructed to reflect progression from hemodialysis initiation. Patients were classified into one of three vascular access choices: maintain CVC, attempt fistula, or attempt graft. We explicitly modeled probabilities of primary and secondary patency for each access type, with success modified by age, sex, and diabetes. Access-specific mortality was incorporated using preexisting cohort data, including terms for age, sex, and diabetes. Costs were ascertained from the 2010 USRDS report and Medicare for procedure costs. An AV fistula attempt strategy was found to be superior to AV grafts and CVCs in regard to mortality and cost for the majority of patient characteristic combinations, especially younger men without diabetes. Women with diabetes and elderly men with diabetes had similar outcomes, regardless of access type. Overall, the advantages of an AV fistula attempt strategy lessened considerably among older patients, particularly women with diabetes, reflecting the effect of lower AV fistula success rates and lower life expectancy. These results suggest that vascular access-related outcomes may be optimized by considering individual patient characteristics. Copyright © 2015 by the American Society of Nephrology.

    We conducted a preliminary IR imaging study of blood circulation in patients with peripheral vascular diseases. Abnormal blood flow is common in older adults, especially those with elevated blood lipids, diabetes, hypertension, and a history of smoking. All of these conditions have a high prevalence in our population, often with more than one condition in the same individual. The differences in blood flow is revealed by temperature differences in areas of the extremities as well as other regions of the body. However, what is needed is an imaging technique that is relatively inexpensive and can reveal the blood flow in real time. The IR imaging can show detailed venous system and small tempearture changes associated with blood flow. Six patients with vascular diseases were tested in a clinic set up. Their legs and feet were imaged. We observed large temperature differences (cooling of more than 10° C) at the foot, especially toes. More valuable information were obtained from the temperature distribution maps. IR thermography is potentially a very valuable tool for medical application, especially for vascular diseases.

    Full Text Available Background: Hemodialysis is a critical treatment method, which depends on the vascular access route. Lack of care for the vascular access route could diminish its efficiency in a short time. Regarding this, the present study aimed to evaluate the frequency of nursing care for vascular access route in the hemodialysis patients. Methods: This cross-sectional study was conducted on 20 nurses and 120 hemodialysis patients, who referred to the Hemodialysis Department of Shahid Beheshti Hospital, Babol, Iran, in 2015. The method of nursing care for vascular access route was evaluated using a researcher-made checklist. The data analysis was performed using the descriptive statistics in the SPSS version 16. Results: In total, 14 cases of nursing care were evaluated, in 100% of which all the caring steps, including wearing gloves and a mask, early bolus injections of heparin, washing the catheter tubing, frequent monitoring of blood pressure, rinsing the catheter tubing, returning the blood to the body after hemodialysis, and sterile covering of the puncture site, were observed. However, some of the other techniques, such as the care related to appropriate pump speed when starting the dialysis machine (81.66%, observance of the needle distance from fistula (75.83%, appropriate placement of catheter (75%, pressing the injection site (54.17%, blood pressure monitoring at the end of dialysis (50%, and change of the needle site between two sessions (27.5%, were not adhered to by the nurses. Conclusion: According to the results of this study, some of the nursing care steps, which are necessary in the beginning and end of the hemodialysis, were not accurately followed by the nurses. It is recommended that constant training courses be held for the nurses in this regard.

    Purpose Alternatives to cytotoxic agents are desirable for patients with HIV-associated Kaposi's sarcoma (KS). Vascular endothelial growth factor-A (VEGF-A) contributes to KS pathogenesis. We evaluated the humanized anti–VEGF-A monoclonal antibody, bevacizumab, in patients with HIV-KS. Patients and Methods Patients with HIV-KS who either experienced progression while receiving highly active antiretroviral therapy (HAART) for at least 1 month or did not regress despite HAART for at least 4 months were administered bevacizumab 15 mg/kg intravenously on days 1 and 8 and then every 3 weeks. The primary objective was assessment of antitumor activity using modified AIDS Clinical Trial Group (ACTG) criteria for HIV-KS. HIV-uninfected patients were also eligible and observed separately. Results Seventeen HIV-infected patients were enrolled. Fourteen patients had been receiving effective HAART for at least 6 months (median, 1 year). Thirteen patients had advanced disease (ACTG T1), 13 patients had received prior chemotherapy for KS, and seven patients had CD4 count less than 200 cells/μL. Median number of cycles was 10 (range, 1 to 37 cycles); median follow-up was 8.3 months (range, 3 to 36 months). Of 16 assessable patients, best tumor responses observed were complete response (CR) in three patients (19%), partial response (PR) in two patients (12%), stable disease in nine patients (56%), and progressive disease in two patients (12%). Overall response rate (CR + PR) was 31% (95% CI, 11% to 58.7%). Four of five responders had received prior chemotherapy for KS. Over 202 cycles, grade 3 to 4 adverse events at least possibly attributed to therapy included hypertension (n = 7), neutropenia (n = 5), cellulitis (n = 3), and headache (n = 2). Conclusion Bevacizumab is tolerated in patients with HIV-KS and has activity in a subset of patients. PMID:22430271

    Objective: The prevalence of peripheral vascular disease (PVD) in patients with coronary artery disease (CAD) has been investigated in many different ways. It depends on the diagnostic methods used and definition of atherosclerotic manifestations in the different vascular beds. This study was carried out to determine the prevalence of PVD in the lower limbs in group of patients with CAD. Design: This is a prospective observational study. Place and duration of study: The study was conducted at Combined Military Hospital/Armed Forces institute of Cardiology, Rawalpindi, over a period of one year (January 1998 to January 1999). Subjects and methods: A total number of 200 patient (171 male and 29 females) aged 55-77 years with CAD. Diagnosed by coronary angiography were included in the study. In all patients blood pressure was recorded in both arms by sphygmomanometer and ankle systolic pressure by Doppler ultrasound. Ankle branchial index was calculated. Demographic data were obtained from the patient's hospital files. Results: The prevalence of PVD was 22.5% in patients with CAD in agreement with the results of most previous investigation. There was tendency towards increasing prevalence of PVD with more advanced CAD. Thirty patients (27%) showed evidence of triple vessel disease as compared to 13 patient (18%) with double vessel and 2 patients (1%) with single vessel disease. Conclusion: A non-invasive investigation of peripheral arterial circulation should be included early in the clinical consideration of patients with chest pain or similar symptoms suggesting coronary artery disease. Ankle systolic pressure appears to be simple and cheap technique for evaluation of results. (author)

    Three recent publications have reported the development of erythema multiforme and Stevens-Johnson syndrome in patients receiving cranial irradiation and sodium phenytoin. Some authors have recommended that patients receiving whole brain radiation therapy and who have had seizures should not be prescribed phenytoin but an alternative anticonvulsant. This article reviews the current literature pertaining to the development of this potentially lethal complication in patients receiving whole brain radiation and phenytoin, with reference to the single recorded case of Stevens-Johnson syndrome in a patient receiving cranial irradiation and phenytoin in Auckland, New Zealand. While the clinical picture in the 16 patients reported in the literature and the current case report differed from the classical form of erythema multiforme, a similar pattern of presentation and outcome appeared in all patients reviewed, suggesting that the combination of phenytoin, cranial irradiation and the gradual reduction of concomitant steroids seem to lead to the development of erythema multiforme and/or Stevens-Johnson syndrome. The data presented, although sparse, suggest that phenytoin should not be prescribed in patients receiving cranial irradiation. 21 refs., 2 tabs., 3 figs.

    The aim of this study was to determine impact of lymph vascular space involvement (LVSI) on recurrence and survival in early stage of endometrial cancer. From 1991 through 2010, all endometrial cancer patients at University Hospital of Bari, Italy were identified. The Log-rank test and Kaplan-Meyer methods were used for time-to-event analysis to evaluate the effects of on lymph vascular space involvement recurrence rate and survival time. Of the 560 endometrial cancer patients, 525 underwent primary surgery. Of those, 399 had early stage disease. Three hundred and forty women were not found to have LVSI, whereas 59 were found to have lymph vascular space involvement. Forty-nine (12%) patients developed a recurrence and 20 of them showed lymph vascular space involvement. The statistical analysis demonstrated that LVSI was strongly associated with a poor survival (P < 0.0001). Lymph vascular space involvement is associated with a high risk of recurrence and poor overall survival in early stage of endometrial cancer; therefore, the clinical decision to decide whether or not a patient with early stage endometrial cancer should receive adjuvant therapy should be included the evaluation of lymph vascular space involvement. © 2013 John Wiley & Sons Ltd.

    The oropharynx and hypopharynx are common sites of involvement in AIDS patients with mucocutaneous Kaposi's sarcoma. The radiotherapist is often asked to intervene with these patients due to problems with pain, difficulty in swallowing, or impending airway obstruction. We have noted an unexpected decrease in normal tissue tolerance of the oropharyngeal mucosa to irradiation in AIDS patients treated in our department. Data on 12 patients with AIDS and Kaposi's sarcoma receiving oropharyngeal irradiation are presented here. Doses ranged from 1000 cGy to 1800 cGy delivered in 150-300 cGy fractions. Seven of eight patients receiving doses of 1200 cGy or more developed some degree of mucositis, four of these developed mucositis severe enough to require termination of treatment. All patients in this study received some form of systemic therapy during the course of their disease, but no influence on mucosal response to irradiation was noted. Four patients received total body skin electron treatments, but no effect on degree of mucositis was seen. Presence or absence of oral candidiasis was not an obvious factor in the radiation response of the oral mucosa in these patients. T4 counts were done on 9 of the 12 patients. Although the timing of the T4 counts was quite variable, no correlation with immune status and degree of mucositis was found. The degree of mucositis seen in these patients occurred at doses much lower than expected based on normal tissue tolerances seen in other patient populations receiving head and neck irradiations. We believe that the ability of the oral mucosa to repair radiation damage is somehow altered in patients with AIDS.

    Full Text Available Objective. To examine the relationship of handgrip strength with forearm blood flow (BF and vascular resistance (VR in rheumatoid arthritis (RA patients. Methods. Forearm BF at rest (RBF and after upper arm occlusion (RHBF, and handgrip strength were examined in 78 individuals (RA=42 and controls (CT=36. Subsequently, VR at rest (RVR and after occlusion (RHVR were calculated. Results. The patients’ RBF (P=0.02 and RHBF (P=0.0001 were less, whereas RVR (P=0.002 and RHVR (P=0.0001 were greater as compared to the CTs. Similarly, handgrip strength was lower in the RAs (P=0.0001. Finally, handgrip strength was directly associated with RBF (r=0.43; P=0.0001, and RHBF (r=0.5; P=0.0001, and inversely related to RVR (r=-0.3; P=0.009 and RHVR (r=-0.3; P=0.007. Conclusion. The present study uniquely identifies an association between regional measures of forearm blood flow and handgrip strength in patients and healthy control. In addition, this study confirms the presence of vascular and muscle dysfunction in patients with rheumatoid arthritis, as evidenced by lower forearm blood flow indices, at rest and following occlusion, and lower handgrip strength as compared to healthy individuals.

    Radiotherapy is considered to be associated with psychological distress. We assessed the mental status, anxiety, and the factors associated with these in cancer patients about to receive radiotherapy. Hospitalized patients about to receive radiotherapy participated. Psychological status was assessed by a psychiatrist, based on interview about the type of anxiety related to cancer or radiotherapy as well as self-rating questionnaires. Eligible data were collected from 94 patients. The incidence of mental disorders was 20%. The total mood disturbance scores were significantly higher in patients with poor performance status. The most common type of anxiety regarding radiotherapy was acute adverse effect, and the predictors were palliative treatment and living alone. Mental disorders, mood disturbance, and anxiety in patients cannot be neglected in radiation oncology practice. Especially careful attention should be paid to patients with these predictive factors.

    Full Text Available Methylenetetrahydrofolate Reductase (MTHFR is key enzyme in metabolism of homocysteine. Homozygotes for mutation (TT genotype have hyperhomocysteinemia, risk factor for atherosclerosis development. The aim of the study was to find out distribution of genotype frequencies of C677T MTHFR among patients on maintenance hemodialysis. Possible association of alleles and genotypes of C677T polymorphism of the MTHFR gene with age of onset, duration of dialysis and cause of kidney failure was studied also. Cross-sectional study includes 80 patients from Clinic of Hemodialysis KUCS in Sarajevo. In order to perform genotyping, isolated DNA was analyzed by RFLP-PCR and gel-electrophoresis. From total of 80 patients, 42.5% (n=24 were female, 57.5% (n=46 were male, mean age 54.59±1.78 years and duration of dialysis 79.92±6.32 months. Genotype distribution was: CC 51.2% (n=41, CT 37.5% (n=30 and TT 11.2% (n=9. Patients with wild-type genotype have longer duration of dialysis in month (87.1 ± 63.93 comparing to TT genotype patients (67.06 ± 39.3, with no statistical significance. T allele frequency was significantly higher in group of vascular and congenital cause of kidney failure (Pearson X2 =6.049, P<0.05 comparing to inflammation etiology group. Genotype distribution results are within the results other studies in Europe. Obtained results indicate that C677T polymorphism is not associated with onset, duration and cause of kidney failure in our hemodialysis population. There is an association of T allele of the MTHFR gene and vascular and congenital cause kidney failure.

    Glucocorticoid-induced osteoporosis (GIOP) is the most common form of secondary osteoporosis, yet few patients receive proper measures to prevent its development. We retrospectively searched prescription records to determine if patients receiving oral prednisolone were receiving prophylaxis or treatment for osteopenia and osteoporosis. Patients who were prescribed greater or equal to 7.5 milligrams of prednisolone for 6 months or longer during a 6- month period were identified through the prescription monitoring system. Demographic and clinical data were extracted from the patient records, and dual energy x-ray absorptiometry (DEXA) scans were retrieved, when available. Use of oral calcium, vitamin D and anti-resorptives was recorded. One hundred males and 65 females were receiving oral prednisolone for a mean (SD) duration of 40.4 (29.9) months in males and 41.2 (36.4) months in females. Twenty-one females (12.7%) and 5 (3%) males had bone mineral density measured by DEXA. Of those, 10 (47.6%) females and 3 (50%) males were osteoporotic and 11(52.4%) females and 2 (40%) males were osteopenic. Calcium and vitamin D were prescribed to the majority of patients (60% to 80%), but none were prescribed antiresorptive/anabolic therapy. Patients in this study were neither investigated properly nor treated according to the minimum recommendations for the management of GIOP. Physician awareness about the prevention and treatment of GIOP should be a priority for the local health care system. (author)

    We measured circulating concentrations of endothelin in healthy subjects and in patients with abnormal vascular reactivity. Endothelin concentrations were determined by radioimmunoassay after extraction of plasma using Sep-Pak C-18 cartridges in healthy subjects, in patients with diabetes mellitus type I, in patients with mild to moderate essential hypertension and in non-dialyzed patients with stable chronic renal failure. Plasma concentrations were similar in healthy controls, in diabetics and in hypertensive patients averaging 5.0±0.6 pg/ml, 4.7±0.2 pg/ml and 6.5±1.0 pg/ml, respectively. In contrast, plasma concentrations of endothelin were markedly elevated in patients with chronic renal failure averaging 16.6±2.9 pg/ml. No correlations were observed between serum creatinine concentrations ranging from 124 to 850 μmol/l or blood pressure and plasma concentrations of endothelin. Bicycle ergometric exercise in six healthy subjects and an acute modest i.v. saline load of 1,000 ml of 0.45% NaCl administered within 60 min in six patients with mild essential hypertension did not affect plasma concentrations of endothelin

    Purpose: Multiple studies have shown survival benefits in patients with cancer treated with radiation therapy, but access to treatment facilities has been found to limit its use. This study was undertaken to examine access issues in Iowa and determine a methodology for conducting a similar national analysis. Patients and Methods: All Iowa residents who received radiation therapy regardless of where they were diagnosed or treated were identified through the Iowa Cancer Registry (ICR). Radiation oncologists were identified through the Iowa Physician Information System (IPIS). Radiation facilities were identified through IPIS and classified using the Commission on Cancer accreditation standard. Results: Between 2004 and 2010, 113,885 invasive cancers in 106,603 patients, 28.5% of whom received radiation treatment, were entered in ICR. Mean and median travel times were 25.8 and 20.1 minutes, respectively, to the nearest facility but 42.4 and 29.1 minutes, respectively, to the patient's chosen treatment facility. Multivariable analysis predicting travel time showed significant relationships for disease site, age, residence location, and facility category. Residents of small and isolated rural towns traveled nearly 3× longer than urban residents to receive radiation therapy, as did patients using certain categories of facilities. Conclusion: Half of Iowa patients could reach their nearest facility in 20 minutes, but instead, they traveled 30 minutes on average to receive treatment. The findings identified certain groups of patients with cancer who chose more distant facilities. However, other groups of patients with cancer, namely those residing in rural areas, had less choice, and some had to travel considerably farther to radiation facilities than urban patients.

    Objective: To evaluate the factors leading to hyperkalemia in patients with cirrhosis receiving spironolactone. Results: Patients with hyperkalemia (K>5 mmol/l) had higher blood urea nitrogen, serum creatinine and bilirubin levels (p=0.004, 0.001 and 0.044 respectively). Their serum sodium and albumin levels were lower (p=0.000 and 0.017 respectively). They had advanced cirrhosis with high Pugh score (p=0.003). These patients were on higher dose of spironolactone (p=0.001). Multivariate analysis showed that dose of spironolactone > 100 mg/day, serum creatinine >1.3 mg/dl, persistence of ascites and edema, and female gender were important predictors of development of hyperkalemia. Conclusion: Patients with cirrhosis receiving high dose of the diuretic, having edema, ascites and high serum creatinine are at the greater risk of developing hyperkalemia during spironolactone therapy.

    To determine the frequency of anxiety and depression in patients undergoing chemotherapy for solid tumors using Hospital Anxiety Depression Scale (HADS). Study Design: Cross sectional descriptive study. Place and Duration of Study: Out-patient department of Armed Forces Institute of Mental Health, Rawalpindi from June 2011 to December 2011. Methodology: Consecutive non probability sampling technique was used to select patients of age (25-70 years), male or female, who had received atleast 03 cycles of chemotherapy for solid tumors. Those with history of prior psychiatric illness, current use of psychotropic medication or psychoactive substance use, and any major bereavement in past one year were excluded from the study. After taking informed consent, relevant socio- demographic data was collected and HADS was administered. HADS-A cut off score of 7 was taken as significant anxiety while a HADS-D cut off score of 7 was taken as significant depression. Results: The total number of participants was 209. The mean age of patients was 42.9 years, with 55.5% males and 44.5% females. Overall 33/209 (15.8%) patients had anxiety while 56/209 (26.8%) were found to have depression. There was a higher frequency of anxiety and depression in younger patients (less than age 40 years), females, patients who were single or divorced, and patients receiving chemotherapy for pancreatic carcinoma. Conclusion: Patients undergoing chemotherapy suffer from considerable levels of anxiety and depression, thus highlighting the need for specialized interventions. (author)

    Sugammadex has steroid-encapsulating effect. This study was undertaken to assess whether the clinical efficacy of sugammadex was altered by the administration of steroids. Sixty patients between 18 and 60 years of age with the American Society of Anesthesiologists I-IV and undergoing elective direct laryngoscopy/biopsy were included in this study. Patients were assigned to two groups based on the intraoperative steroid use: those who received steroid (Group S) and who did not (Group C). After standard general anesthesia, patients were monitored with the train of four (TOF) monitoring. The preferred steroid and its dose, timing of steroid administration, and TOF value before and after sugammadex as well as the time to recovery (TOF of 0.9) were recorded. SPSS software version 17.0 was used for statistical analysis. There is no statistically significant difference between groups in terms of age, gender, preoperative medication use, and TOF ratio just before administering sugammadex. The reached time to TOF 0.9 after sugammadex administration was significantly shorter in Group S than Group C (P sugammadex as well as the dose of sugammadex in those who received prednisolone; time to TOF 0.9 was higher in prednisolone receivers as compared to dexamethasone receivers (P sugammadex was found, in contrast with what one expect. Further studies are required to determine the cause of this effect which is probably due to a potential interaction between sugammadex and steroids.

    The main purpose of this article is to examine whether cognitive plasticity increases after cognitive training in Alzheimer's disease patients. Twenty six patients participated in this study, all of them diagnosed with mild Alzheimer's disease, 17 of them received a cognitive training program during 6 months, and the other 9 were assigned to the control group. Participants were assigned to experimental or control conditions for clinical reasons. In order to assess cognitive plasticity, all patients were assessed before and after treatment with three subtests from the "Bateria de Evaluación de Potencial de Aprendizaje en Demencias" [Assessment Battery of Learning Potential in Dementia] (BEPAD). After treatment, Alzheimer's disease patients improved their performance in all the tasks assessing cognitive plasticity: viso-spatial memory, audio-verbal memory and verbal fluency. However, the cognitive plasticity scores of the patients in the control group decreased. In conclusion, this study showed that cognitive stimulation programs can improve cognitive functioning in mildly demented patients, and patients who do not receive any cognitive interventions may reduce their cognitive functioning.

    Objective Antidepressant management for older patients receiving home health care (HHC) may occur through two pathways: nurse-physician collaboration (without patient visits to the physician) and physician management through office visits. This study examines the relative contribution of the two pathways and how they interplay. Methods Retrospective analysis was conducted using Medicare claims of 7,389 depressed patients 65 or older who received HHC in 2006–7 and who possessed antidepressants at the start of HHC. A change in antidepressant therapy (vs. discontinuation or refill) was the main study outcome and could take the form of a change in dose, switch to a different antidepressant, or augmentation (addition of a new antidepressant). Logistic regressions were estimated to examine how use of home health nursing care, patient visits to physicians, and their interactions predict a change in antidepressant therapy. Results About 30% of patients experienced a change in antidepressants versus 51% who refilled and 18% who discontinued. Receipt of mental health specialty care was associated with a statistically significant, 10–20 percentage-point increase in the probability of antidepressant change; receipt of primary care was associated with a small and statistically significant increase in the probability of antidepressant change among patients with no mental health specialty care and above-average utilization of nursing care. Increased home health nursing care in absence of physician visits was not associated with increased antidepressant change. Conclusions Active antidepressant management resulting in a change in medication occurred on a limited scale among older patients receiving HHC. Addressing knowledge and practice gaps in antidepressant management by primary care providers and home health nurses and improving nurse-physician collaboration will be promising areas for future interventions.

    To explore the efficacy and safety of thalidomide for the treatment of delayed vomiting, induced by chemotherapy in cancer patients. Study Design: Randomized, double-blind controlled study. Place and Duration of Study: The Oncology Department of Affiliated Hospital of Xuzhou Medical University, Jiangsu Xuzhou, China, from January 2012 to January 2014. Methodology: A total of 78 cancer patients, who had delayed vomiting observed from 24 hours to 1 week after chemotherapy, were included in the study. Patients were divided in a treatment group (40 patients, 51.28%) and a control group (38 patients, 48.71%). The treatment group received thalidomide at an oral dose of 100 mg per night; 50 mg was added daily up to a dose of 200 mg per night, if the curative effect was suboptimal and the medicine was tolerated. Both the treatment and the control groups received a drip of 10 mg azasetron 30 minutes before chemotherapy. The control group only proportions of antiemetic effects and adverse reactions were compared using the ?2 test. Antiemetic effects and adverse reactions were assessed from Odds Ratios (OR) with 95% Confidence Intervals(95% CI). Results: The effective control rate of delayed vomiting in the treatment group was significantly higher than that in the control group (?2=5.174, p=0.023). No significant difference was found between the two groups in other adverse effects of chemotherapy. Karnofsky scores or the overall self-evaluation of the patients (p>0.05). Conclusion: Thalidomide can effectively control the delayed vomiting of cancer patients receiving chemotherapy and the adverse reactions of the agent can be tolerated.

    Full Text Available AIM: This study was performed in a descriptive matter to determine the views of inpatients at an oncology state hospital on receiving bad news. METHOD: The study sample consisted of 237 inpatients (155 females, 82 males at an oncology state hospital between October and November 2008 who were determined using the random sampling method and accepted participating in the study. The data collection tool used was a survey form that consisted of 24 questions related to the sociodemographic features and views on receiving bad news. RESULTS: The mean age of the study subjects was 53.1±13.9 (min.=18, max.=83. The patients were undergoing the treatment process in 84% and the diagnostic process in 16%. The bad news had been given by the physician in 87.8% and while in the physician's room in 74.8%. The patients had been told while receiving the bad news that 'there is a mass/problem/lesion/tumor and you will undergo surgery' in 47.7% while 24.9% had been told that they had cancer directly. The patients stated that they froze, fainted, were shocked, felt their life was shattered and experienced emotions such as sadness, fear, hopelessness, sorrow, disappointment, desperation, etc. at a rate of 93.7%. We found that 58.2% of the patients had not been given an opportunity to express their emotions when they received the bad news, 67.4% preferred to have a relative with them at the time, 40.9% felt that the bad news should be given in a special environment, 30% wanted the bad news to be given as soon as the diagnosis was known while 36.7% preferred being told everything about the disease when receiving the bad news CONCLUSION: Taking into account the information content, family participation, and the individual preferences of the patients regarding time and place when giving bad news and encouraging them to ask questions and express themselves may make it easier for the patients to cope with bad news.

    Vascular access is a potentially life-saving procedure that is a mainstay of emergency medicine practice. There are a number of challenges associated with obtaining and maintaining vascular access, and the choice of the route of access and equipment used will depend on patient- and provider-specific factors. In this issue, the indications and complications of peripheral intravenous access, intraosseous access, and central venous access are reviewed. Timely and effective assessment and management of difficult-access patients, pain control techniques that can assist vascular access, and contraindications to each type of vascular access are also discussed.

    We analyzed the premorbid biographies of 21 patients with Alzheimer's disease for possible common features. Eleven age-matched patients suffering from vascular dementia served as a control group. The observations from our qualitative study indicate that persons with a conflict-avoiding, submissive, premorbid personality predominate among Alzheimer patients. Persons who later became Alzheimer patients tended to leave important daily-life decisions to their partners (or other persons of reference). Prior to the onset of the very first neuropsychological deficits, persons who later became Alzheimer patients were found to stay in a lasting situation in which they were subject to a treatment that could be designated as "caring tutelage." Subsequently, most patients became subject to an increasingly patronizing and restricting treatment. Further elements that were frequently found as part of the premorbid development were physical or psychological burden, loss of social contacts, and loss of motivation. In contrast, assertive and dominant premorbid traits predominated in the group of vascular patients. The premorbid biographical situation of persons who later became vascular patients was characterized by a loss of the control which these persons had hitherto exerted over partners, their families, or the situation at their working place. We advance the hypothesis that in Alzheimer's disease the described psychological phenomena are part of a preclinical process, during which biological, psychological, and social factors interact, finally joining into the clinical stage of the disease. Possibilities for psychotherapeutic interventions are discussed.

    Purpose: To review and describe our institution's outcomes in patients treated with external beam radiotherapy after keloid excision. Methods and Materials: This was a retrospective study. Patients who received radiotherapy between July 1994 and January 2004 after keloid excision were identified. A questionnaire was mailed regarding sociodemographic factors, early and late radiation toxicities, the need for additional therapy, and satisfaction level. All patients had received a total of 15 Gy in three daily 5-Gy fractions. Treatment started within 24 h after surgery and was delivered on a Siemens orthovoltage machine. The data were analyzed using the STATA statistical package. Results: A total of 234 patients were approached. The response rate was 41%, and 75% were female. The mean age was 36.5 years (range, 16-69 years). The patients were mainly of European (53.1%) or African (19.8%) descent. For early toxicity outcomes, 54.2% reported skin redness and 24% reported skin peeling. For late toxicity outcomes, 27% reported telangiectasia and 62% reported permanent skin color changes. No association was found with gender, skin color, or age for the late toxicity outcomes. Of the patients responding, 14.6% required adjuvant treatment. On a visual scale of 1-10 for the satisfaction level, 60% reported a satisfaction level of ≥8. Telangiectasia was the most significant predictor of a low satisfaction level (≤3, p < 0.005). Conclusion: The results of our study have shown that orthovoltage-based radiotherapy after surgical excision for keloids is a good method for the prevention of relapse. It is well tolerated, causes little toxicity, and leads to a high patient satisfaction level

    Patients with cirrhosis display hypocontractility of splanchnic vessels because of dysregulation of vasoactive proteins, such as decreased effect of RhoA/ROCK and increased activity of β-Arrestin-2 and eNOS. However, it is unknown whether the dysregulation of vasoactive proteins is displayed in other vessels. We investigated whether expression of vasoactive proteins can be evaluated in gastric mucosa vessels. Biopsies from the gastric mucosa of 111 patients with cirrhosis were collected at three different centres and from 13 controls. Forty-nine patients had received TIPS. Portal pressure gradient was measured in 49 patients with TIPS and in 16 patients without TIPS. Biopsies from the antrum were conserved in formaldehyde for immunohistochemistry or shock-frozen for PCR and Western blot. The mucosal transcription of vascular markers (αSMA, CD31) was higher in cirrhotic patients than controls, which was confirmed by immunohistochemistry. On average, relative mucosal levels of RhoA and ROCK were lower, while β-Arrestin-2 levels were higher in cirrhotic patients compared to controls. Transcriptional levels of eNOS increased with presence of ascites and grade of oesophageal varices. Patients with TIPS showed less pronounced markers of vascular dysfunction in gastric mucosa. This is the first evidence that the expression of vasoactive proteins in mucosa from the gastric antrum of patients with cirrhosis reflects their vascular dysfunction and possibly changes after therapeutic interventions. © 2014 John Wiley & Sons A/S.

    Retention of uremic metabolites is a proposed cause of cognitive impairment in patients with ESRD. We used metabolic profiling to identify and validate uremic metabolites associated with impairment in executive function in two cohorts of patients receiving maintenance dialysis. We performed metabolic profiling using liquid chromatography/mass spectrometry applied to predialysis plasma samples from a discovery cohort of 141 patients and an independent replication cohort of 180 patients participating in a trial of frequent hemodialysis. We assessed executive function with the Trail Making Test Part B and the Digit Symbol Substitution test. Impaired executive function was defined as a score ≥2 SDs below normative values. Four metabolites-4-hydroxyphenylacetate, phenylacetylglutamine, hippurate, and prolyl-hydroxyproline-were associated with impaired executive function at the false-detection rate significance threshold. After adjustment for demographic and clinical characteristics, the associations remained statistically significant: relative risk 1.16 (95% confidence interval [95% CI], 1.03 to 1.32), 1.39 (95% CI, 1.13 to 1.71), 1.24 (95% CI, 1.03 to 1.50), and 1.20 (95% CI, 1.05 to 1.38) for each SD increase in 4-hydroxyphenylacetate, phenylacetylglutamine, hippurate, and prolyl-hydroxyproline, respectively. The association between 4-hydroxyphenylacetate and impaired executive function was replicated in the second cohort (relative risk 1.12; 95% CI, 1.02 to 1.23), whereas the associations for phenylacetylglutamine, hippurate, and prolyl-hydroxyproline did not reach statistical significance in this cohort. In summary, four metabolites related to phenylalanine, benzoate, and glutamate metabolism may be markers of cognitive impairment in patients receiving maintenance dialysis.

    The technique of in vivo total body neutron activation analysis was used to measure total body calcium (TBCa), a sensitive and precise index of skeletal mass, expressed as the Ca ratio (TBCa observed/TBCa predicted). 23 unselected, ambulatory, noninstitutionalized, adult epileptic patients under long-term anticonvulsant therapy were studied. Ca ratio was normal in 20 of the patients, low in only 2 and borderline in 1 patient. Plasma alkaline phosphatase values were elevated in half the subjects. Plasma Ca (uncorrected) was in the normal range in all. Serum 25-hydroxvitamin D (25-OHD) was low in 67% of the subjects, but only 1 patient had a value below 5 ng/ml. There was no correlation between the Ca ratio and the alkaline phosphatase or 25-OHD values. No radiographic or other evidences of osteomalacia were observed. This study does not support the notion of a prevalence of osteopenia in ambulatory, noninstitutionalized, adult epileptic patients receiving chronic anticonvulsant therapy in this geographical area despite the frequent findings of biochemical abnormalities.

    Objective To test the performance of appetite assessment tools among patients receiving hemodialysis. Design Cross-sectional. Setting Seven dialysis facilities in Northern California. Subjects 221 patients receiving hemodialysis. Intervention We assessed five appetite assessment tools [self-assessment of appetite, subjective assessment of appetite, visual analogue scale (VAS), Functional Assessment of Anorexia/Cachexia Therapy (FAACT) score and the Anorexia Questionnaire (AQ)]. Main outcome measures Reported food intake, normalized protein catabolic rate (nPCR), and change in body weight were used as criterion measures, and we assessed associations among the appetite tools and biomarkers associated with nutrition and inflammation. Patients were asked to report their appetite and the percentage of food eaten (from 0% to 100%) during the last meal compared to usual intake. Results Fifty-eight (26%) patients reported food intake ≤50% (defined as poor appetite). The prevalence of anorexia was 12% by self-assessment of appetite, 6% by subjective assessment of appetite, 24% by VAS, 17% by FAACT score, and 12% by AQ. All tools were significantly associated with food intake ≤50% (pappetite. The FAACT score and the VAS had the strongest association with food intake ≤50% (c-statistic 0.80 and 0.76). Patients with food intake ≤50% reported weight loss more frequently than patients without low intake (36% vs 22%) and weight gain less frequently (19% vs 35%; p=0.03). nPCR was lower among anorexic patients based on the VAS (1.1 ± 0.3 vs 1.2 ± 0.3, p=0.03). Ln IL-6 correlated inversely with food intake (p=0.03), but neither IL-6 nor CRP correlated with any of the appetite tools. Furthermore, only the self-assessment of appetite was significantly associated with serum albumin (p=0.02), prealbumin (p=0.02) and adiponectin concentrations (p=0.03). Conclusions Alternative appetite assessment tools yielded widely different estimates of the prevalence of anorexia in

    Diabetes is the leading cause of lower limb amputation in Australia. However, due to limited resources, it is not feasible for everyone with diabetes to access podiatry care, and some objective guidelines of who should receive podiatry is required. A total of 250 patients with neuropathy (Biothesiometer; Biomedical Instruments, Newbury, Ohio, USA) ( > 30, age podiatry care (mean of estimates from 10 reports), the NNT to prevent one foot ulcer per year was: no neuropathy (vibration perception threshold (VPT) 30) alone, NNT = 45; +cannot feel monofilament, NNT = 18; +previous ulcer/amputation, NNT = 7. Provision of podiatry care to diabetic patients should not be only economically based, but should also be directed to those with reduced sensation, especially where there is a previous history of ulceration or amputation.

    Purpose: Gastrointestinal injury occurs rarely with agents that affect the vascular endothelial growth factor receptor and with abdominal stereotactic body radiation therapy (SBRT). We explored the incidence of serious bowel injury (SBI) in patients treated with SBRT with or without vascular endothelial growth factor inhibitor (VEGFI) therapy. Methods and Materials: Seventy-six patients with 84 primary or metastatic intra-abdominal lesions underwent SBRT (median dose, 50 Gy in 5 fractions). Of the patients, 20 (26%) received VEGFI within 2 years after SBRT (bevacizumab, n=14; sorafenib, n=4; pazopanib, n=1; sunitinib, n=1). The incidence of SBI (Common Terminology Criteria for Adverse Events, version 4.0, grade 3-5 ulceration or perforation) after SBRT was obtained, and the relationship between SBI and VEGFI was examined. Results: In the combined population, 7 patients (9%) had SBI at a median of 4.6 months (range, 3-17 months) from SBRT. All 7 had received VEGFI before SBI and within 13 months of completing SBRT, and 5 received VEGFI within 3 months of SBRT. The 6-month estimate of SBI in the 26 patients receiving VEGFI within 3 months of SBRT was 38%. No SBIs were noted in the 63 patients not receiving VEGFI. The log–rank test showed a significant correlation between SBI and VEGFI within 3 months of SBRT (P=.0006) but not between SBI and radiation therapy bowel dose (P=.20). Conclusions: The combination of SBRT and VEGFI results in a higher risk of SBI than would be expected with either treatment independently. Local therapies other than SBRT may be considered if a patient is likely to receive a VEGFI in the near future.

    Full Text Available Background: Knowledge of correct information-seeking behavior by the patients can provide health specialists and health information specialists with valuable information in improving health care. This study aimed to investigate the passive receipt and active seeking of health information by diabetic patients. Materials and Methods: A survey method was used in this research on 6426 diabetic patients of whom 362 patients were selected by a no percentage stratified random sampling. The Longo information-seeking behavior questionnaire was used to collect data and they were analyzed by SPSS 20 software. Results: The most common information source by diabetic patients was practitioners (3.12. The minimum usage among the information sources were from charity organizations and emergency phone lines with a usage of close to zero. The amount of health information gained passively from each source has the lowest average of 4.18 and usage of this information in making health decision has the highest average score of 5.83. Analysis of the data related to active seeking of information showed that knowledge of available medical information from each source has the lowest average score of 3.95 and ability in using the acquired information for making medical decisions has the highest average score of 5.28. The paired t-test showed that differences between passive information receipt (41.68 and active information seeking (39.20 considered as statistically significant (P < 0.001. Conclusion: Because diabetic patients are more passive information receivers than active information seekers, the health information must be distributed by passive means to these patients. In addition, information-seeking behavior during different time periods should be investigated; to identify more effective distribution of health information.

    To investigate the clinical factors predicting outcomes of leiomyoma treated with uterine artery embolization (UAE). A total of 183 uterine leiomyoma patients undergoing UAE were retrospectively analyzed. Patient age, characteristics of vascular supply in magnetic resonance imaging (MRI)/digital subtraction angiography (DSA), number, size and location of leiomyoma were recorded. Leiomyoma regrowth, new leiomyoma appearance and recurrence of any previously reported symptoms were carefully monitored over a mean follow-up of 30 months (median 32 months, range 12-80). Potential recurrence risk factors were analyzed by univariate and multivariate cox regression analysis. Twenty-three recurrences were recorded. The difference in the vascularity classification systems between MRI and DSA was not statistically significant (P = 0.059). High vascularity in MRI, high vascularity in DSA and multiple leiomyoma showed a significant risk of recurrence using univariate and multivariate analysis (P = 0.004, P leiomyoma recurrence (P > 0.05). Low vascularity and solitary leiomyoma indicated favourable outcomes in patients treated with UAE. • Low vascularity and solitary mass predicted favourable outcomes in UAE-treated patients. • MRI might provide information on vascularity in leiomyoma before UAE. • Variations in vascular supply, age, size, location were not associated with recurrence.

    To describe the experience of family members of patients receiving palliative sedation at the initiation of treatment and after the patient has died and to compare these experiences over time.
. Descriptive comparative study.
. Oncology ward at Shaare Zedek Medical Center in Jerusalem, Israel.
. A convenience sample of 34 family members of dying patients receiving palliative sedation. 
. A modified version of a questionnaire describing experiences of family members with palliative sedation was administered during palliative sedation and one to four months after the patient died. Descriptive statistics were used to describe the results of the questionnaire, and appropriate statistical analyses were conducted for comparisons over time.
. Experiences of family members and time.
. Most relatives were satisfied with the sedation and staff support. Palliative sedation was experienced as an ethical way to relieve suffering. However, one-third felt that it shortened the patient's life. An explanation of the treatment was given less than half of the time and was usually given on the same day treatment was started. This explanation was given by physicians and nurses. Many felt that they were not ready for changes in the patient's condition and wanted increased opportunities to discuss the treatment with oncology care providers. No statistically significant differences in experiences were found over time. 
. Relatives' experiences of palliative sedation were generally positive and stable over time. Important experiences included timing of the initiation of sedation, timing and quality of explanations, and communication.
. Nurses should attempt to initiate discussions of the possible role of sedation in the event of refractory symptoms and follow through with continued discussions. The management of refractory symptoms at the end of life, the role of sedation, and communication skills associated with decision making related to palliative sedation should be a

    Full Text Available BACKGROUND Human Immunodeficiency Virus (HIV was discovered in 1986 in Chennai (India amongst female sex workers by Dr. Suniti Solomon. Since then, HIV has spread to all parts of the country from the high-risk group to the antepartum population in many states at an alarming rate. The prevalence of dyslipidaemia and other risk factors for cardiovascular disease is significant in HIV/AIDS patients receiving highly active antiretroviral therapy (HAART, ranging from 20% to 80%. In view of the high prevalence of dyslipidaemia and the increased risk for cardiovascular diseases among patients with HIV/AIDS, this is a matter of concern for public health. MATERIALS AND METHODS 143 patients who had been receiving HAART for a minimum of two years from Rajiv Gandhi Institute of Medical Sciences, Kadapa, during the period of January 2015 to September 2016 were studied. They were divided into 4 regimens groups 1 TEL (Tenofovir, Efavirenz, Lamivudine 2 TLAR (Tenofovir, Lamivudine, Atazanavir, Ritonavir 3 ZLE (Zidovudine, Lamivudine, Efavirenz 4 ZLN (Zidovudine, Lamivudine, Nevirapine. Detailed history, demographic data, anthropometric measurements, serum lipid profile obtained and analysed. RESULTS Out of 143 patients, 90 (62.9% were males and 53 (37.1% were females. 68 (47.6% were in the 30-39 years age group accounted for maximum percentage of groups. Based on BMI only 3 (2.1% were obese, 24 (16.8% were of overweight. WaistHip ratio was abnormal in 117 (81.8% and 26 (18.2% were normal. The mean values for patients on TEL regimen are TC is 195.4 mg%, LDL 122.1 mg%, HDL 34.96 mg%, TG 194.02 mg% and TC/HDL is 5.5714. In patients treated with TLAR regimen the mean values of TC are 172.15 mg%, LDL 99.15 mg %, HDL 36.35 mg%, TG 183.35 mg% and TC/HDL is 4.8. In patients treated with ZLE regimen, TC is 201.64 mg%, LDL 123.27 mg%, HDL 35.68 mg%, TG 212.27 mg% and TC/HDL is 5.6364. In patients treated with ZLN regimen, TC is 162.1 mg%, LDL 91.94 mg%, HDL 35.98 mg%, TG

    To evaluate the predictive value of three-dimensional (3D)-power Doppler sonography on recurrent miscarriage. The study patients were divided into a recurrent miscarriage group (30 cases) and a normal pregnancy group (21 cases). Measurement of endometrial thickness was performed using two-dimensional transvaginal ultrasound in the midluteal phase. The endometrial volume, vascularization index (VI), flow index (FI), and vascularization-flow index (VFI) in midluteal and placenta volume, as well as the VI, FI, and VFI of early pregnancy were measured using Virtual Organ Computer-aided Analysis of 3D-power Doppler ultrasound. Endometrial thickness, endometrial volume, endometrial vascular data, VI, FI, and VFI of the midluteal phase were lower in the recurrent miscarriage group compared with the normal pregnancy group (p FI between the recurrent miscarriage and control groups during early pregnancy (p > 0.05). The predictive accuracy of endometrial thickness, endometrial volume, VI, FI, and VFI in the midluteal phase, and placenta volume, VI, FI, and VFI in early pregnancy as measured by the receiver operating characteristic curve to predict miscarriage before 12 gestational weeks in participants was 0.681, 0.876, 0.770, 0.720, 0.879, 0.771, 0.907, 0.592, respectively. The 3D-power Doppler ultrasound is a more comprehensive and sensitive method for evaluating endometrial receptivity. Endometrial volume, VI, FI, and VFI in the midluteal phase, as well as VI in early pregnancy, can be considered as predictive factors for recurrent miscarriage. Copyright © 2015.

    Objectives of the prospective, open-label study were to investigate pharmacokinetics of doripenem and determine appropriate doripenem regimens during continuous hemodiafiltration (CHDF) in critically ill patients with renal failure (creatinine clearance times during one dosing interval were measured in order to calculate pharmacokinetic parameters and clearance via hemodiafiltration. Mean half-life (+/-standard deviation) of doripenem was 7.9+/-3.7 hours. Total body clearance of doripenem was 58.0+/-12.7 ml/min, including clearance of 13.5+/-1.6 ml/min via CHDF. An IV dose of 250 mg of doripenem every 12 hours during CHDF provided adequate plasma concentrations for critically ill patients with renal failure, without resulting in accumulation upon steady-state. Thus, under the conditions tested, CHDF appeared to have little effect on doripenem clearance. Therefore, the blood level of doripenem can be satisfactorily controlled by adjustment of doripenem dose and dosing interval, in accordance with residual renal function in patients receiving CHDF.

    As vascular procedures become more complex, patient understanding of their treatment(s) can become more difficult. We wished to evaluate the utility of multimedia presentations (MPs) to improve patient understanding of their vascular interventions. Patients undergoing endovascular aneurysm repair (EVAR), peripheral angioplasty, Hickman catheter and peripherally inserted central catheter (PICC) insertion were randomized into a control group receiving traditional verbal consent, and a MP group that were shown a two minute simplified video of their procedure on an iPad™ computer in addition to the traditional verbal consent. After obtaining consent, all patients completed a questionnaire assessing their comprehension of the procedure, and satisfaction with the consent process. Satisfaction was rated on a 5 point Likert scale with 5 being 'very helpful' in understanding the procedure. Ninety-three patients were recruited for this study, 62% of which were male. The intervention significantly increased total comprehension in all procedure types controlling for procedure type (multimedia vs. control; F = 9.14, P = .003). A second ANOVA showed there was a significant main effect by intervention (F = 44.06, p consent process to be helpful in patient understanding and that there is improved satisfaction. Given the rapid rate of innovation in vascular interventions, increased regular use of MPs to help patients understand their procedures would be beneficial in the care of patients undergoing vascular interventions.

    The outcome and complications which developed in 8 hemodialysis patients who received 12 DiaTAP bioCarbon button vascular-access devices were reviewed. All patients had a poor vascular access history. Three of twelve devices have been replaced because of thrombosis and two because of infection. Four patients have had 10 episodes of reduced blood flow. Streptokinase infusion into the DiaTAP button led to improved blood flow in 8 of 10 episodes. The 6-month survival rate of the DiaTAP access device was 67% and the average functioning life was 9.4 months. It was a valuable form of access when others had failed.

    Diabetes mellitus is associated with an enhanced risk for cardiovascular disease and its prevalence is increasing. Diabetes induces metabolic stress on blood and vascular cells, promoting platelet activation and vascular dysfunction. The level of vascular cell activation can be measured by the number and phenotype of microparticles found in the circulation. The aim of this study was to investigate the effect of a platelet-inhibitory dose of aspirin on the number and type of microparticles shed to the circulation. Forty-three diabetic patients were enrolled in the study and received a daily dose of 100mg of aspirin for 10 days to cover the average platelet life-span in the circulation. Before and after the intervention period, circulating microparticles were characterized and quantified by flow cytometry. Type 1 diabetic patients had about twice the number of tissue factor-positive circulating microparticles (derived both from platelets and monocytes) and endothelial-derived E-selectin positive microparticles than type 2 diabetic patients. Aspirin therapy significantly inhibited platelets since cyclooxygenase 1 derived thromboxane generation levels were reduced by 99%. Microparticles derived from erythrocytes, activated monocytes, and smooth muscle cells were significantly reduced after 10 days of aspirin administration. These results indicate that: a) vascular and blood cells in type 1 diabetic patients are exposed to more sustained stress shown by their specific microparticle origin and levels; b) aspirin therapy inhibits vascular wall cell activation and microparticle shedding, and c) the effects of aspirin are similar in type 1 and 2 diabetes.

    Full Text Available Background Prolonged mechanical ventilation is increasingly common. It is expensive and associated with significant morbidity and mortality. Our objective is to comprehensively characterize patients admitted to a Ventilator Rehabilitation Unit (VRU for weaning and identify characteristics associated with survival. Methods 182 consecutive patients over 3.5 years admitted to Temple University Hospital (TUH VRU were characterized. Data were derived from comprehensive chart review and a prospectively collected computerized database. Survival was determined by hospital records and social security death index and mailed questionnaires. Results Upon admission to the VRU, patients were hypoalbuminemic (albumin 2.3 ± 0.6 g/dL, anemic (hemoglobin 9.6 ± 1.4 g/dL, with moderate severity of illness (APACHE II score 10.7 + 4.1, and multiple comorbidities (Charlson index 4.3 + 2.3. In-hospital mortality (19% was related to a higher Charlson Index score ( P = 0.006; OR 1.08-1.6, and APACHE II score ( P = 0.016; OR 1.03-1.29. In-hospital mortality was inversely related to admission albumin levels ( P = 0.023; OR 0.17-0.9. The presence of COPD as a comorbid illness or primary determinant of respiratory failure and higher VRU admission APACHE II score predicted higher long-term mortality. Conversely, higher VRU admission hemoglobin was associated with better long term survival (OR 0.57-0.90; P = 0.0006. Conclusion Patients receiving prolonged ventilation are hypoalbuminemic, anemic, have moderate severity of illness, and multiple comorbidities. Survival relates to these factors and the underlying illness precipitating respiratory failure, especially COPD.

    Full Text Available Churg-Strauss syndrome is a rare disorder, but in patients with asthma it may develop as an adverse effect of the administered drugs. The aim of this study was to investigate possible causal relationship between montelukast and the occurrence of Churg-Strauss syndrome. Medical literature was reviewed by searching the databases 'Medline' and 'Googlescholar', in order to detect published cases of Churg-Strauss syndrome associated with use of montelukast. In this article is included 13 publications which contain the following keywords: montelukast, Churg-Strauss syndrome and side effects. Relationship between use of montelukast and development of Churg-Strauss syndrome was not clearly causal, although montelukast was associated with development and relapse of the syndrome. This fact supports the hypothesis that leukotriene antagonists are involved in the pathogenesis of this serious disease. Special attention should be paid to appearance of new symptoms in an asthmatic patient, already treated with corticosteroids, who start receiving leukotriene antagonists, especially if the dose of corticosteroids is reduced. Definitive confirmation or rejection of the hypothesis that leukotriene antagonists are directly involved in the development of this syndrome require further investigations.

    1999-01-01

    To elucidate effects of sodium ethamsylate (SE) on anticoagulant and antiaggregation activity of vascular endothelium in patients suffering from hemorrhagic fever with renal syndrome (HFRS). A trial of SE enrolled 70 HFRS patients (58 males, 12 females aged under 30 years) compatible by the disease severity. They were divided into two groups. 42 patients of the control group received standard therapy, 28 patients of the study group received adjuvant 12% solution of SE in daily dose 1500-2000 mg in the course of HFRS oliguria period. Hemostatic parameters were measured before and after the cuff test to investigate the condition of vascular wall with calculation of the athrombogenicity index (the ratio of the relevant indices before and after the cuff test). SE effects on vascular endothelium was assessed by a blind method. In oliguria, both groups had baseline antiaggregation indices significantly higher than in the control. After the cuff test, control patients' indices tended to an increase while in the study group there was a marked decrease. The trend in anticoagulant activity of microvascular endothelium did not differ much with the groups. This picture persisted also in polyuria. In convalescence hemostasis was similar in both groups. SE enhances antiaggregant activity of vascular endothelium in oliguria period of HFRS without affecting its anticoagulant properties. This is explained by a direct effect of SE on vascular endothelium.

    Nurses noted that the rate of phlebitis was high when intravenous amiodarone was infused via a peripheral site. Hospital policy recommends a central vascular catheter, but this method is often not feasible because the drug is administered in emergent situations for short periods. To determine the rate and severity of phlebitis in patients given peripherally infused amiodarone. The literature, policy, and procedures for administration of amiodarone were reviewed; the pharmacy was consulted; and a data collection tool was developed. The tool was pilot tested and revised, and face validation was established. Data were collected during a 6-month period. A convenience sample was used. The study included a total of 12 patients. Each new infusion of intravenous amiodarone was considered a separate occurrence, for a total of 24 infusions. Various grades of phlebitis developed in 8 patients (67%). Phlebitis developed at 12 of the 24 infusion sites (50%). Patients receiving peripherally infused amiodarone are at high risk for phlebitis. This complication may lead to infection, additional medical intervention, delay in treatment, and prolonged hospitalization.

    Central vascular cannulation is not a risk-free procedure, especially in pediatric patients. Newborn and infants are small and low-weighted, their vascular structures have high mobility because of tissue laxity and their vessels are superficial and with small diameter. These characteristics, together with the natural anatomical variability and poor collaboration of small children, make this technique more difficult to apply. Therefore, ultrasound imaging is increasingly being used to locate vessels and guide vascular access in this population. (a) To present a model that simulates the vascular system for training ultrasound-guided vascular access in pediatrics patients; (b) to ultrasound-guided vascular cannulation in the model. The model consisted of two components: (a) muscular component: avian muscle, (b) vascular component: elastic tube-like structure filled with fluid. 864 ecoguided punctures was realized in the model at different vessel depth and gauge measures were simulated, for two medical operators with different degree of experience. The average depth and diameter of vessel cannulated were 1.16 (0.42)cm and 0.43 (0.1)cm, respectively. The average number of attempts was of 1.22 (0.62). The percentage of visualization of the needle was 74%. The most frequent maneuver used for the correct location, was the modification of the angle of the needle and the relocation of the guidewire in 24% of the cases. The average time for the correct cannulations was 41 (35.8)s. The more frequent complications were the vascular perforation (11.9%) and the correct vascular puncture without possibility of introducing the guidewire (1.2%). The rate of success was 96%. The model simulates the anatomy (vascular and muscular structures) of a pediatric patient. It is cheap models, easily reproducible and a useful tool for training in ultrasound-guided puncture and cannulation. Copyright © 2015 Elsevier España, S.L.U. y SEMICYUC. All rights reserved.

    assess whether the current protein intake recommendations may improve the biochemical parameters of critical patients receiving parenteral nutrition. longitudinal study with three evaluations made (during the first 72 hours, on the 7th and the 14th days of PN). The following tests were applied: albumin, C-reactive protein, prealbumin, total cholesterol, HDL, triglycerides, lymphocytes, and glutathione peroxidase. The severity was determined by SOFA. The statistical analysis included the Spearman and Mann-Whitney tests, as well as ANOVA (analysis of variance). among the 53 patients evaluated, 20 (37.74%) died. The mean calorie was 24.68 ± 9.78 kcal/kg (beginning of PN), 26.49 ± 8.89 kcal/kg (3rd to 7th days of PN), and 30.9 ± 12.19 kcal/kg (7th to 14th days of PN). The mean protein was 1.19 ± 0.44 g/kcal/kg (first 72 hours of PN), 1.29 ± 0.44 g/kcal/kg (3rd to 7th days of PN) and 1.49 ± 0.69 g/kcal/kg (7th to 14th days of PN). Prealbumin, albumin, total cholesterol and HDL were below the reference values, while the CRP levels were high. Throughout the three evaluation times, there was no a significant improvement on the levels of laboratory examinations. A strong and negative correlation was found between SOFA and prealbumin (r = -0.64, p = 0.05). the protein offer, according to the traditional recommendations, was not enough to improve the biochemical parameters of critical patients undergoing parenteral nutrition.

    Music intervention has been shown to reduce anxiety and sedative exposure among mechanically ventilated patients. Whether music intervention reduces ICU costs is not known. The aim of this study was to examine ICU costs for patients receiving a patient-directed music intervention compared with patients who received usual ICU care. A cost-effectiveness analysis from the hospital perspective was conducted to determine if patient-directed music intervention was cost-effective in improving patient-reported anxiety. Cost savings were also evaluated. One-way and probabilistic sensitivity analyses determined the influence of input variation on the cost-effectiveness. Midwestern ICUs. Adult ICU patients from a parent clinical trial receiving mechanical ventilatory support. Patients receiving the experimental patient-directed music intervention received a MP3 player, noise-canceling headphones, and music tailored to individual preferences by a music therapist. The base case cost-effectiveness analysis estimated patient-directed music intervention reduced anxiety by 19 points on the Visual Analogue Scale-Anxiety with a reduction in cost of $2,322/patient compared with usual ICU care, resulting in patient-directed music dominance. The probabilistic cost-effectiveness analysis found that average patient-directed music intervention costs were $2,155 less than usual ICU care and projected that cost saving is achieved in 70% of 1,000 iterations. Based on break-even analyses, cost saving is achieved if the per-patient cost of patient-directed music intervention remains below $2,651, a value eight times the base case of $329. Patient-directed music intervention is cost-effective for reducing anxiety in mechanically ventilated ICU patients.

    Full Text Available There is a lack of data about daily difficulties and life quality, especially among young patients having arteriovenous fistula (AVF affected by (pseudoaneurysm. In this retrospective cohort study, 195 patients with AVF were followed up from May to June 2015. An unstandardized questionnaire was used for the evaluation of patients’ screening needs and expectations. Retired married men in their sixties, with completed secondary education, represented the majority of patients with AVF in this study. The patients had a positive attitude towards the disease and AVF, and they received the majority of information related to the care and treatment of AVF from the medical personnel and doctors in selected dialysis centers. Employed, well-educated single men, aged between 21 and 40 years, had the highest interest in having an aesthetic correction of AVF, especially due to the formation of (pseudoaneurysm at the AVF site. Establishment of rules for reconstructive procedures of AVF, once circulatory and hemodynamic stability is achieved after renal transplantation, is suggested in addition to establishing criteria for determining vascular access affected by (pseudoaneurysm.

    Inter-arm systolic blood pressure difference (SBPD) is an easily obtained patient characteristic which relates to vascular disease. We aimed to identify determinants of large inter-arm SBPD and to investigate the relation between inter-arm SBPD and vascular events in patients with and without manifest vascular disease. In a cohort of 7344 patients with manifest vascular disease or vascular risk factors alone enrolled in the Second Manifestations of ARTerial disease (SMART) study, single bilateral non-simultaneous blood pressure measurements were performed. Logistic and Cox regression was used to identify determinants of large inter-arm SBPD (≥15mmHg) and to investigate the relation between inter-arm SBPD and vascular events (composite of non-fatal myocardial infarction, stroke, and vascular mortality) and all-cause mortality. In all patients the median inter-arm SBPD was 7mmHg (IQR 3-11) and 1182 (16%) patients had inter-arm SBPD ≥15mmHg. Higher age, higher systolic blood pressure, diabetes mellitus, peripheral artery disease, carotid artery stenosis, higher carotid intima-media thickness, and lower ankle-brachial indices were related to large inter-arm SBPD (≥15mmHg). Each 5mmHg increase in inter-arm SBPD was related to a 12% higher risk of vascular events in patients without manifest vascular disease (HR 1.12; 95% CI 1.00-1.27), whereas no relation was apparent in patients with manifest vascular disease (HR 0.98; 95% CI 0.93-1.04, interaction p-value 0.036). Inter-arm SBPD was not related to all-cause mortality (HR 1.05; 95% CI 0.93-1.19). Inter-arm SBPD relates to a higher risk of vascular events in patients without manifest vascular disease, whereas this relation is not apparent in patients with manifest vascular disease.

    Vascular access infections are of concern to hemodialysis patients and nurses. Best demonstrated practices (BDPs) have not been developed for home hemodialysis (HHD) access use, but there have been generally accepted practices (GAPs) endorsed by dialysis professionals. We developed a survey to gather information about training provided and actual practices of HHD patients using the NxStage System One HHD machine. We used GAP to assess training used by nurses to teach HHD access care and then assess actual practice (adherence) by HHD patients. We also assessed training and adherence where GAPs do not exist. We received a 43% response rate from patients and 76% response from nurses representing 19 randomly selected HHD training centers. We found that nurses were not uniformly instructing HHD patients according to GAP, patients were not performing access cannulation according to GAP, nor were they adherent to their training procedures. Identification of signs and symptoms of infection was commonly trained appropriately, but we observed a reluctance to report some signs and symptoms of infection by patients. Of particular concern, when aggregating all steps surveyed, not a single nurse or patient reported training or performing all steps in accordance with GAP. We also identified practices for which there are no GAPs that require further study and may or may not impact outcomes such as infection. Further research is needed to develop strategies to implement and expand GAP, measure outcomes, and ultimately develop BDP for HHD to improve infectious complications. © 2014 The Authors.

    Vessel embolization can be a valuable adjunct procedure in transjugular intrahepatic portosystemic shunt (TIPS). During the creation of a TIPS, embolization of portal vein collaterals supplying esophageal varices may lower the risk of secondary rebleeding. And after creation of a TIPS, closure of the TIPS itself may be indicated if the resulting hepatic encephalopathy severely impairs mental functioning. The Amplatzer Vascular Plug (AVP; AGA Medical, Golden Valley, MN) is well suited for embolization of large-diameter vessels and has been employed in a variety of vascular lesions including congenital arteriovenous shunts. Here we describe the use of the AVP in the context of TIPS to embolize portal vein collaterals (n = 8) or to occlude the TIPS (n = 2)

    2016-12-01

    Patients with chronic kidney disease (CKD) are prone to vascular calcification. Pathogenetic mechanisms of vascular calcifications have been broadly studied and discussed such as the role of hyperphosphatemia, hypercalcemia, parathormone, and vitamin D. In recent years, new insights have been gained pointing to vitamin K as a main actor. It has been discovered that vitamin K is an essential cofactor for the activation of matrix Gla protein (MGP), a calcification inhibitor in the vessel wall. Patients with CKD often suffer from vitamin K deficiency, resulting in low active MGP and eventually a lack of inhibition of vascular calcification. Vitamin K supplementation and switching warfarin to new oral anticoagulants are potential treatments. In addition, MGP may have a role as a non-invasive biomarker for vascular calcification.

    Cerebral microinfarcts (CMIs) are small ischemic lesions that are a common neuropathological finding in patients with stroke or dementia. CMIs in the cortex can now be detected in vivo on 3 Tesla MRI. To determine the occurrence of CMIs and associated clinical features in patients with possible vascular cognitive impairment (VCI). 182 memory-clinic patients (mean age 71.4±10.6, 55% male) with vascular injury on brain MRI (i.e., possible VCI) underwent a standardized work-up including 3 Tesla MRI and cognitive assessment. A control group consisted of 70 cognitively normal subjects (mean age 70.6±4.7, 60% male). Cortical CMIs and other neuroimaging markers of vascular brain injury were rated according to established criteria. Occurrence of CMIs was higher (20%) in patients compared to controls (10%). Among patients, the presence of CMIs was associated with male sex, history of stroke, infarcts, and white matter hyperintensities. CMI presence was also associated with a diagnosis of vascular dementia and reduced performance in multiple cognitive domains. CMIs on 3 Tesla MRI are common in patients with possible VCI and co-occur with imaging markers of small and large vessel disease, likely reflecting a heterogeneous etiology. CMIs are associated with worse cognitive performance, independent of other markers of vascular brain injury.

    Full Text Available Acute disorders of cerebral circulation remain serious medical and social problem associated with high disability and mortality rates. Since 2011 Tomsk oblast is a participating member of the medical campaign aimed at improved medical services to the vascular patients. The preliminary implementation data analysis for 2012 revealed improvement of most of the indices of medical support to patients suffering from acute cerebral circulation; increased number of the in-patient cases (Regional Vascular Center and primary vascular department, decreased lethality rates from strokes, specifically hemorrhagic cases. Strict observance of the Regulations on Medical Assistance for stroke patients and the using of modern methods of therapy allowed to decrease hospital mortality in the Primary Vascular Departments and early mortality in the Regional Vascular Center. The active implementation of neurorehabilitation approaches resulted in the increased number of patients who do not require third parties’ assistance. Analysis of the work of the departments helped to identifying current problems and perspectives of further development of special medical care for stroke patients.

    Although much has been written about excess cost and duration of stay (DOS) associated with surgical site infections (SSIs) after cardiothoracic surgery, less has been reported after vascular and general surgery. We used data from the National Surgical Quality Improvement Program (NSQIP) to estimate the total cost and DOS associated with SSIs in patients undergoing general and vascular surgery. Using standard NSQIP practices, data were collected on patients undergoing general and vascular surgery at a single academic center between 2007 and 2009 and were merged with fully loaded operating costs obtained from the hospital accounting database. Logistic regression was used to determine which patient and preoperative variables influenced the occurrence of SSIs. After adjusting for patient characteristics, costs and DOS were fit to linear regression models to determine the effect of SSIs. Of the 2,250 general and vascular surgery patients sampled, SSIs were observed in 186 inpatients. Predisposing factors of SSIs were male sex, insulin-dependent diabetes, steroid use, wound classification, and operative time (P surgery. Although the excess costs and DOS associated with SSIs after general and vascular surgery are somewhat less, they still represent substantial financial and opportunity costs to hospitals and suggest, along with the implications for patient care, a continuing need for cost-effective quality improvement and programs of infection prevention.

    Objective Scleroderma patients with autoantibodies to centromere proteins (CENPs) and/or interferon-inducible protein 16 (IFI16) are at increased risk of severe vascular complications. We set out to define whether these autoantigens are enriched in cells of the vasculature. Methods Successive stages of embryoid bodies (EBs) as well as vascular progenitors were used to evaluate the expression of scleroderma autoantigens IFI16 and CENP by immunoblotting. CD31 was included to mark early blood vessels. IFI16 and CD31 expression were defined in skin paraffin sections from scleroderma patients and from healthy controls. IFI16 expression was determined by flow cytometry in circulating endothelial cells (CECs) and circulating progenitor cells (CPCs). Results Expression of CENP-A, IFI16 and CD31 was enriched in EBs at days 10 and 12 of differentiation, and particularly in cultures enriched in vascular progenitors (IFI16, CD31, CENPs A and-B). This pattern was distinct from that of comparator autoantigens. Immunohistochemical staining of skin paraffin sections showed enrichment of IFI16 in CD31-positive vascular endothelial cells in biopsies from scleroderma patients and normal controls. Flow cytometry analysis revealed IFI16 expression in CPCs, but minimal expression in CECs. Conclusion Expression of scleroderma autoantigens IFI16 and CENPs, which are associated with severe vascular disease, is increased in vascular progenitors and mature endothelial cells. High level, lineage-enriched expression of autoantigens may explain the striking association between clinical phenotypes and the immune targeting of specific autoantigens. PMID:27159521

    Full Text Available Blood stasis syndrome (BSS in traditional Asian medicine has been considered to correlate with the extent of atherosclerosis, which can be estimated using the cardioankle vascular index (CAVI. Here, the diagnostic utility of CAVI in predicting BSS was examined. The BSS scores and CAVI were measured in 140 stroke patients and evaluated with respect to stroke risk factors. Receiver operating characteristic (ROC curve analysis was used to determine the diagnostic accuracy of CAVI for the diagnosis of BSS. The BSS scores correlated significantly with CAVI, age, and systolic blood pressure (SBP. Multiple logistic regression analysis showed that CAVI was a significant associate factor for BSS (OR 1.55, P=0.032 after adjusting for the age and SBP. The ROC curve showed that CAVI and age provided moderate diagnostic accuracy for BSS (area under the ROC curve (AUC for CAVI, 0.703, P<0.001; AUC for age, 0.692, P=0.001. The AUC of the “CAVI+Age,” which was calculated by combining CAVI with age, showed better accuracy (0.759, P<0.0001 than those of CAVI or age. The present study suggests that the CAVI combined with age can clinically serve as an objective tool to diagnose BSS in stroke patients.

    Vascular calcifications on the preoperative radiograph of patients scheduled for total knee arthroplasty (TKA) often give rise to concern, as their clinical relevance remains uncertain. The aim of this study was to investigate whether these vascular calcifications - especially medial artery calcifications (MACs), which increase arterial stiffness - were associated with tourniquet failure and thus with increased intraoperative blood loss. A total of 765 patients who underwent primary TKA with a tourniquet (cuff pressure 350 mmHg) between 2009 and 2011 were screened for vascular calcifications on the preoperative radiograph. Vascular calcifications were classified into intimal and medial artery calcifications. Intraoperative blood loss of patients with and without MAC was compared, and a mixed linear regression model was used to adjust for the presence of several confounding factors (e.g., obesity, operating time). None of the 50 (6.5%) patients with MAC showed signs of tourniquet failure. Intraoperative blood loss of patients with MAC was not significantly elevated compared to the overall study group (p = 0.592) even when corrected for the presence of several confounding factors. We found no evidence that vascular calcifications seen on the preoperative radiograph might be associated with tourniquet failure. However, surgeons should be aware of this possibility as tourniquet failure might become more common considering the ongoing trend toward minimizing cuff pressures. (orig.)

    primary health care services for other reasons. The aim of the present study is to describe the differential characteristics of AD patients in primary care, distinguishing between those who receive treatment and those who do not, and their reasons for not seeking it. In a cross-sectional study patients were evaluated by their general practitioner (GP) and interviewed by a member of the research team. Sociodemographic, diagnostic and clinical data were collected. From 1,372 patients interviewed in Catalonia, 118 (8.6%) were diagnosed as AD. These patients showed a lower socioeconomic status (48.3% vs 33.3%, odds ratio 2.02), higher unemployment rates (32.2% vs 19.2 %, odds ratio 2.11), and greater psychological distress and disability. Patients with AD receiving treatment (16.9%), were older (44 vs 36 years of age), reported higher unemployment rates (66% vs 25.5%, odds ratio 6.32) and higher daily alcohol consumption (61.5 vs 23.7 grams), suggesting a more advanced disease. Patients with AD in general showed a higher degree of comorbidity compared to other patients, with patients in treatment showing the most elevated level. The main reasons given for not seeking treatment were shame, fear of giving up drinking and barriers to treatment. Taken together, the data suggest the need to implement earlier strategies for the detection and treatment of AD.

    White matter lesions (WMLs) and cerebral infarcts are common findings in Alzheimer disease and may contribute to dementia severity. WMLs and lacunar infarcts may provide a potential target for intervention strategies. This study assessed whether multicomponent vascular care in patients with Alzheimer disease with cerebrovascular lesions slows progression of WMLs and prevents occurrence of new infarcts. A randomized controlled clinical trial, including 123 subjects, compared vascular care with standard care in patients with Alzheimer disease with cerebrovascular lesions on MRI. Progression of WMLs, lacunes, medial temporal lobe atrophy, and global cortical atrophy were semiquantitatively scored after 2-year follow-up. Sixty-five subjects (36 vascular care, 29 standard care) had a baseline and a follow-up MRI and in 58 subjects, a follow-up scan could not be obtained due to advanced dementia or death. Subjects in the vascular care group had less progression of WMLs as measured with the WML change score (1.4 versus 2.3, P=0.03). There was no difference in the number of new lacunes or change in global cortical atrophy or medial temporal lobe atrophy between the 2 groups. Vascular care in patients with Alzheimer disease with cerebrovascular lesions slows progression of WMLs. Treatment aimed at vascular risk factors in patients with early Alzheimer disease may be beneficial, possibly in an even earlier stage of the disease.

Recommended pharmacologic therapies include antiplatelets, angiotensin converting enzyme (ACE inhibitors, and HMG-CoA-reductase inhibitors (statins. Purpose: We studied the degree to which patient admission to a vascular surgery service increased the use of these therapies. Patients and methods: The authors conducted a retrospective chart review of 150 patients with PAD admitted to the vascular surgery service at a large Canadian tertiary care hospital. The use of recommended pharmacologic therapies at the time of admission and discharge were compared. A multidisciplinary clinical team established criteria by which patients were deemed ineligible to receive any of the recommended therapies. Angiotensin receptor blockers (ARBs were considered an alternative to ACE inhibitors. Results: Prior to hospital admission, 64% of patients were on antiplatelet therapy, 67% were on an ACE inhibitor or ARB, and 71% were on a statin.

    Full Text Available Objectives. Diabetes is a major health problem associated with hyperglycemia and chronically increased oxidative stress and enhanced formation of advanced glycation end-products (AGEs. The aim of this study was to determine whether oxidative plasma biomarkers in diabetic patients could be evidenced and associated with vascular complications. Methods. Oxidative stress biomarkers such as thiols, ischemia-modified albumin (IMA, glycated albumin (GA, fructosamine, and AGEs were measured in 75 patients with poorly controlled type 2 diabetes (HbA1c > 7.5% with (44 or without (31 vascular disease and in 31 nondiabetic controls. Results. Most biomarkers of oxidation and glycation were significantly increased in diabetic patients in comparison with nondiabetics. Fructosamines, GA, IMA, and AGEs were positively correlated and levels of fluorescent AGEs were significantly increased in the plasma from patients presenting vascular complication. Conclusions. These results bring new evidence for the potential interest of glycated albumin, oxidative stress, and glycoxidation parameters in the monitoring of type 2 diabetic patients. Furthermore, it emphasizes fluorescent AGEs as a putative indicator for vascular event prediction in diabetic patients.

    Evaluation of the Janus kinase 2 (JAK2) V617F mutation has been widely used for the diagnosis of myeloproliferative neoplasms (MPN). However, its prognostic relevance to clinical outcome is not completely understood. We investigated the association of JAK2 V617F with vascular events in Korean patients with myeloproliferative neoplasms (MPN). We studied 283 patients from 15 centers, who were diagnosed with MPN. The JAK2 V617F status was evaluated by allele-specific polymerase chain reaction (PCR) and sequencing. The patients' diagnoses were essential thrombocythemia (ET n = 146), polycythemia vera (PV n = 120), primary myelofibrosis (n = 12), and unclassifiable MPN (MPNu n = 5). JAK2 V617F was detected in 89 (61%) patients with ET, 103 (86%) with PV, four (33%) with myelofibrosis, and four (80%) with MPNu. A higher number of leukocytes, haemoglobin levels and BM cellularity as well as an older age, lower platelet counts, and diagnosis of PV were significantly correlated with JAK2 V617F. Eighty-three and 43 episodes of thrombosis and bleeding occurred in 100 patients each before and after the diagnosis. Vascular events more frequently occurred in 37% of patients with JAK2 V617F than in 29% of those without the mutation (p = 0.045). Among 175 patients whose samples were available for sequencing, 28 patients with homozygous JAK2 V617F had vascular events more frequently (57%) than those who were heterozygotes (39%) or had the wild type (27%) (p = 0.03). The multivariate analysis showed that a JAK2 homozygous mutation, hypercholesterolemia and older age were independent risk factors for a vascular event. The results of this study showed that Korean patients with MPN had a similar JAK2 mutation rate and frequency of vascular events when compared to Western patients. The presence of V617F was significantly related to vascular events. Therefore, initial evaluation for the JAK2 mutation and careful monitoring for vascular events should be performed in MPN patients.

    Almonds reduce cardiovascular disease risk via cholesterol reduction, anti-inflammation, glucoregulation, and antioxidation. The objective of this randomized, controlled, cross-over trial was to determine whether the addition of 85 g almonds daily to a National Cholesterol Education Program (NCEP) Step 1 diet (ALM) for 6 weeks would improve vascular function and inflammation in patients with coronary artery disease (CAD). A randomized, controlled, crossover trial was conducted in Boston, MA to test whether as compared to a control NCEP Step 1 diet absent nuts (CON), incorporation of almonds (85 g/day) into the CON diet (ALM) would improve vascular function and inflammation. The study duration was 22 weeks including a 6-weeks run-in period, two 6-weeks intervention phases, and a 4-weeks washout period between the intervention phases. A total of 45 CAD patients (27 F/18 M, 45-77 y, BMI = 20-41 kg/m(2)) completed the study. Drug therapies used by patients were stable throughout the duration of the trial. The addition of almonds to the CON diet increased plasma α-tocopherol status by a mean of 5.8%, reflecting patient compliance (P ≤0.05). However, the ALM diet did not alter vascular function assessed by measures of flow-mediated dilation, peripheral arterial tonometry, and pulse wave velocity. Further, the ALM diet did not significantly modify the serum lipid profile, blood pressure, C-reactive protein, tumor necrosis factor-α or E-selectin. The ALM diet tended to decrease vascular cell adhesion molecule-1 by 5.3% (P = 0.064) and increase urinary nitric oxide by 17.5% (P = 0.112). The ALM intervention improved the overall quality of the diet by increasing calcium, magnesium, choline, and fiber intakes above the Estimated Average Requirement (EAR) or Recommended Dietary Allowance (RDA). Thus, the addition of almonds to a NECP Step 1 diet did not significantly impact vascular function, lipid profile or systematic inflammation in CAD patients receiving

    The objective of the research is to estimate the effective dose that patients receive during the procedure of interventional vascular radiology screening using a digital system. The effective dose is the best indicator of radiological risks. A plane ionization camera is used to estimate dose per surface area (Gy/square cm). By means of the method described in the NRPB R-262 report, projections were selected which adjust to the field irradiated in each of the procedures analysed. The product values of the dose surface and effective dose has been 75.7 Gy/cm 2 and 10.5 mSv for abdominal angiography; 29.0 Gy/cm 2 and 7.6 mSv for arteriographic diagnosis of the inferior members; 104.5 Gy/cm 2 and 23.6 mSv for gall drainage; 90.5 Gy/cm 2 and 21.5 mSv for varicoceles, and 39.5 Gy/cm 2 and 9.6 mSv for nephrostomas

    Introduction: Ischemic heart disease is the main cause of death in Uruguay and cancer is the second. The pillar of the systemic treatment of colorectal cancer are fluo pyrimidines and cause acute ischemic events in 3-8% of t rated patients. The 5 fluorouracil is the third anticancer drug most used Objective: Due to the high incidence of the two diseases and the risk of death caused by the ischemic treatment complications, the literature is analyzed to define how to study patients who receive fluo pyrimidines as a medium of preventing the same. Development: fluo pyrimidines cardio-toxicity can occur by myocardial toxicity, vasospasm, dihydropyrimidine dehydrogenase deficiency, autoimmune phenomena, platelet hyper aggregability, etc. The clinic is varied and underestimated: angina, abnormal ST silent and reversible, arrhythmias, heart failure, hypertension and heart failure. It is the most common complication with continuous infusion of 5 Fu and its equivalent capecitabine with bolus f lou pyrimidines. It is common that ischemic heart disease prioritises the risk increase of complications, but their absence does not exist. Without ischemic heart disease it is difficult to prevent ischemic events, however proposes that the older higher risk. Results: No uniform guidelines is advised: detailed history, determine if risk factors such as smoking, hypertension, diabetes and dyslipidemia and They are present electrocardiogram and cardiac evaluation. Warn the patient about angina l pain as early symptom and monitor symptoms during chemotherapy including cardio-vascular hypotension. Discontinue the medication and perform classic anti-angina l symptoms and / or signs of ischemia. Not reintroduce unless it is the only therapeutic option, since mortality may exceed

    Tofacitinib is an oral, small molecule Janus kinase inhibitor that is being investigated for ulcerative colitis (UC). Tofacitinib is approved for rheumatoid arthritis and psoriatic arthritis, where it has been shown to increase herpes zoster (HZ) risk. We evaluated HZ risk among UC patients using tofacitinib. HZ cases were identified in tofacitinib phase II/III/ongoing, open-label, long-term extension (OLE) UC trials. We calculated HZ incidence rates (IRs) per 100 patient-years of tofacitinib exposure within phase III maintenance (Maintenance Cohort) and phase II/III/OLE (Overall Cohort) studies, stratified by baseline demographics and other factors. HZ risk factors were evaluated in the Overall Cohort using Cox proportional hazard models. Overall, 65 (5.6%) patients developed HZ. Eleven patients had multidermatomal involvement (2 nonadjacent or 3-6 adjacent dermatomes), and 1 developed encephalitis (resolved upon standard treatment). Five (7.7%) events led to treatment discontinuation. HZ IR (95% confidence interval [CI]) in the Overall Cohort was 4.07 (3.14-5.19) over a mean (range) of 509.1 (1-1606) days, with no increased risk observed with increasing tofacitinib exposure. IRs (95% CI) were highest in patients age ≥65 years, 9.55 (4.77-17.08); Asian patients, 6.49 (3.55-10.89); patients with prior tumor necrosis factor inhibitor (TNFi) failure, 5.38 (3.86-7.29); and patients using tofacitinib 10 mg twice daily, 4.25 (3.18-5.56). Multivariate analysis identified older age and prior TNFi failure as independent risk factors. In tofacitinib-treated UC patients, there was an elevated risk of HZ, although complicated HZ was infrequent. Increased HZ rates occurred in patients who were older, Asian, or had prior TNFi failure (NCT00787202, NCT01465763, NCT01458951, NCT01458574, NCT01470612).

    Full Text Available In this study, we demonstrated the importance of telomerase protein expression and determined the relationships among telomerase, endothelin-1 (ET-1 and myofibroblasts during early and late remodeling of parenchymal and vascular areas in usual interstitial pneumonia (UIP using 27 surgical lung biopsies from patients with idiopathic pulmonary fibrosis (IPF. Telomerase+, myofibroblasts α-SMA+, smooth muscle cells caldesmon+, endothelium ET-1+ cellularity, and fibrosis severity were evaluated in 30 fields covering normal lung parenchyma, minimal fibrosis (fibroblastic foci, severe (mural fibrosis, and vascular areas of UIP by the point-counting technique and a semiquantitative score. The impact of these markers was determined in pulmonary functional tests and follow-up until death from IPF. Telomerase and ET-1 expression was significantly increased in normal and vascular areas compared to areas of fibroblast foci. Telomerase and ET-1 expression was inversely correlated with minimal fibrosis in areas of fibroblast foci and directly associated with severe fibrosis in vascular areas. Telomerase activity in minimal fibrosis areas was directly associated with diffusing capacity of the lung for oxygen/alveolar volume and ET-1 expression and indirectly associated with diffusing capacity of the lungs for carbon monoxide and severe fibrosis in vascular areas. Cox proportional hazards regression revealed a low risk of death for females with minimal fibrosis displaying high telomerase and ET-1 expression in normal areas. Vascular dysfunction by telomerase/ET-1 expression was found earlier than vascular remodeling by myofibroblast activation in UIP with impact on IPF evolution, suggesting that strategies aimed at preventing the effect of these mediators may have a greater impact on patient outcome.

    Despite the vast amount of scientific literature available on electroconvulsive therapy (ECT), there is little qualitative focus upon the patients' subjective experience of this procedure. Using an exploratory descriptive methodology, this study aims to provide a more unique insight into what certain patients actually think of ECT. Semistructured interviews were conducted to explore eight patients' opinions and experiences of ECT. Interviews were subjected to analysis by a five-step framework approach that identified prominent themes in relation to five broad questions and in conjunction with issues raised by the subjects themselves. Eleven major themes were identified. Four of these were chosen for discussion, not only as the most prevalent themes (in terms of how frequently they were mentioned by the subjects), but also as the most striking (in regards to the intensity of emotions evoked, or their influence on their perception of ECT as a future treatment option). The four themes are fear of ECT, attribution of cognitive decline and memory loss to ECT, positive ECT experiences, and patients' suggestions. Using such a qualitative approach, the depth of the information obtained has revealed new perspectives on how patients perceive the experience of ECT. Fears reported by patients present an opportunity to address specific areas of the procedure that generate the most angst. These were closely associated with recommendations that many patients proposed throughout the interviews. Patients' perceptions of the cognitive effects of ECT do not necessarily correspond with those commonly reported in the literature on ECT. Positive experiences with ECT were more complex than simply its efficacy. There is a need for future research in order to explore and address patients' experiences of ECT.

    This article describes measurements made in the bed station of Clinic of Nuclear Medicine in St. Elizabeth Oncological Institute in Bratislava. There are treated thyroid cancer and thyrotoxicosis with the use of 131 I. The aim of the measurements was to determine the possibility of the ambulation treatment of thyrotoxicosis or the possibility of shortening of the patient;s stay in the bed station that the effective dose would not be exceeded suggestions according to the publication of EURATOM. The measurements were made also with thyroid cancer patients but owing to clinical reasons the ambulation treating in this case is not permissible. Therefore this article does not describe the results of these measurements.The effective dose rates were measured in 0.25 m; 0.5 m; 1 m and 2 m distances from the patient's thyroid so the effective dose in the patient's surroundings could be determined. To the present time the results of effective dose rates measurements for 17 patients were evaluated by described way. The age of the patients was from 41 to 82 years, the administered quantity of 131 I was from 259 to 481 MBq, in fractions 37 MBq, 74 MBq, or 111 MBq. The calculated effective half-life of 131 I excretion from the patients body is crucial for the length of patient's necessary staying in the bed station, were from 4.2 days to 8 days. This great extend of values is given by by the different clinical parameters of the treated patients. After the analyse of them can be said that the effective half-life increases, when the patient is elder, has greater mass of thyroid and the accumulation is higher. At the present time authors don't suggest using the ambulation treatment of thyrotoxicosis by 131 I. For discharging the patient from the hospital authors suggest to think criteria according to the model of behaviour D with the effective dose limit 0.5 mSv. For the households with children up to 2 years and/or pregnant women according to the model B with effective dose limit 0

    In diabetics, hyperglycemia results in deficient endothelial progenitors and cells, leading to cardiovascular complications. We aim to engineer 3-dimensional (3D) vascular networks in synthetic hydrogels from type 1 diabetes mellitus (T1D) patient-derived human-induced pluripotent stem cells (hiPSCs), to serve as a transformative autologous vascular therapy for diabetic patients. We validated and optimized an adherent, feeder-free differentiation procedure to derive early vascular cells (EVCs) with high portions of vascular endothelial cadherin-positive cells from hiPSCs. We demonstrate similar differentiation efficiency from hiPSCs derived from healthy donor and patients with T1D. T1D-hiPSC-derived vascular endothelial cadherin-positive cells can mature to functional endothelial cells-expressing mature markers: von Willebrand factor and endothelial nitric oxide synthase are capable of lectin binding and acetylated low-density lipoprotein uptake, form cords in Matrigel and respond to tumor necrosis factor-α. When embedded in engineered hyaluronic acid hydrogels, T1D-EVCs undergo morphogenesis and assemble into 3D networks. When encapsulated in a novel hypoxia-inducible hydrogel, T1D-EVCs respond to low oxygen and form 3D networks. As xenografts, T1D-EVCs incorporate into developing zebrafish vasculature. Using our robust protocol, we can direct efficient differentiation of T1D-hiPSC to EVCs. Early endothelial cells derived from T1D-hiPSC are functional when mature. T1D-EVCs self-assembled into 3D networks when embedded in hyaluronic acid and hypoxia-inducible hydrogels. The capability of T1D-EVCs to assemble into 3D networks in engineered matrices and to respond to a hypoxic microenvironment is a significant advancement for autologous vascular therapy in diabetic patients and has broad importance for tissue engineering. © 2015 American Heart Association, Inc.

    Purpose: Evaluation of the efficacy and safety of percutaneous treatment of vascular stenoses and occlusions in pediatric liver transplant recipients. Methods: Fifteen children (mean age 8.3 years) underwent interventional procedures for 18 vascular complications after liver transplantation. Patients had stenoses or occlusions of portal veins (n = 8), hepatic veins (n = 3), inferior vena cava (IVC; n = 2) or hepatic arteries (n = 5). Technical and clinical success rates were evaluated. Results: Stent angioplasty was performed in seven cases (portal vein, hepatic artery and IVC), and sole balloon angioplasty was performed in eight cases. One child underwent thrombolysis (hepatic artery). Clinical and technical success was achieved in 14 of 18 cases of vascular stenoses or occlusions (mean follow-up 710 days). Conclusion: Pediatric interventional radiology allows effective and safe treatment of vascular stenoses after pediatric liver transplantation (PLT). Individualized treatment with special concepts for each pediatric patient is necessary. The variety, the characteristics, and the individuality of interventional management of all kinds of possible vascular stenoses or occlusions after PLT are shown

    To determine the utility for detecting ischemic heart disease (IHD), dipyridamole thallium myocardial images (DIP-Tl) have been performed in 103 patients with atherosclerotic vascular disease who can't exercise fully. Of the 103 patients, there were 36 patients with arteriosclerosis obliterans (ASO), 31 patients with aneurysm of the abdominal aorta (AAA), 24 patients with aneurysm of the thoracic aorta (TAA) and 12 patients with dissecting aortic aneurysm (DAA). Clinical evidence of IHD was found in 20 patients with ASO, 10 with AAA, 7 with TAA and 4 with DAA. Positive evidence of DIP-Tl was identified in 66% of 41 patients who had clinical evidence of IHD, and particularly in the patients with AAA (80%) and ASO (65%). On the other hand, in the patients without clinical evidence of IHD, positive evidence of DIP-Tl was identified in 19% of 62 patients and particularly in the patients with AAA (39%). In all patients, the percentage of the positive DIP-Tl ratio was 38%. And, when the 38% patients of the positive DIP-Tl were added to the patients of the negative DIP-Tl who had clinical evidence of IHD, almost half patients (51%) were considered to be complicated with IHD. This study suggests that the atherosclerotic vascular disease is highly complicated with IHD and DIP-Tl is useful to detect IHD. (author)

    A postal survey of British and Irish interventional radiologists was carried out in 1991 to assess current practice with respect to sedation and monitoring of patients during angiography and interventional procedures. The response rate was 65%, 49% of patients are fasted prior to angiography and 68% prior to interventional procedures. Radiologists participate in obtaining consent in 60% of cases. Patients are often (50%) sedated for angiography and usually (62-94% depending on the procedure) sedated for interventional procedures. Nurses are present for most procedures, but are given the task of monitoring the patient's vital signs in only 49% of cases. Anaesthetists are present for less than 10% of interventional procedures. The findings indicate a wide variation in practice and a need to standardize practice at a uniform high level. (author).

    One hundred and twenty-four patients with DSM-III-R dementia were assessed with a standardized battery which included the Geriatric Mental State Schedule, the History and Aetiology Schedule, the Secondary Dementia Schedule and the CAMCOG. Patients with Alzheimer's disease, vascular dementia and senile dementia of Lewy body type (SDLT) all had a similar degree of cognitive impairment at the time of the baseline interview. Patients with Alzheimer's disease and vascular dementia each experienced a mean decline of 27 points in patients with SDLT. Patients with SDLT had a significantly greater decline of verbal fluency than both the other groups. Women were significantly more impaired than men at the time of the baseline assessment but experienced a similar decline during the year of follow-up.

    Patients with rheumatoid arthritis (RA) treated with disease-modifying antirheumatic drugs are susceptible to severe infections such as leishmaniasis. As L. infantum is endemic in the Mediterranean region, it is necessary to rule this infectious process out in any RA patient presenting with fever and pancytopenia. An early diagnosis based on a high suspicion can prevent a fatal outcome. Copyright © 2016 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.

    Swimming exercise is an ideal and excellent form of exercise for patients with osteoarthritis (OA). However, there is no scientific evidence that regular swimming reduces vascular dysfunction and inflammation and elicits similar benefits compared with land-based exercises such as cycling in terms of reducing vascular dysfunction and inflammation in patients with OA. Forty-eight middle-aged and older patients with OA were randomly assigned to swimming or cycling training groups. Cycling training was included as a non-weight-bearing land-based comparison group. After 12 weeks of supervised exercise training, central arterial stiffness, as determined by carotid-femoral pulse wave velocity, and carotid artery stiffness, through simultaneous ultrasound and applanation tonometry, decreased significantly after both swimming and cycling training. Vascular endothelial function, as determined by brachial flow-mediated dilation, increased significantly after swimming but not after cycling training. Both swimming and cycling interventions reduced interleukin-6 levels, whereas no changes were observed in other inflammatory markers. In conclusion, these results indicate that regular swimming exercise can exert similar or even superior effects on vascular function and inflammatory markers compared with land-based cycling exercise in patients with OA who often has an increased risk of developing cardiovascular disease.

    The occurrence of a brain tumor or intracranial vascular lesion during pregnancy is a rare event, but when it happens, it jeopardizes the lives of both the mother and infant. It also creates challenges of a neurosurgical, obstetric, and ethical nature. A multidisciplinary approach should be used for their care. Between 1986 and 2015, 12 pregnant women diagnosed with brain tumors and 17 women with intracranial vascular lesion underwent treatment at the Neurosurgery Department of the Servidores do Estado Hospital and Rede D'Or/São Luis. The Neurosurgery Department teamed up with Obstetrics Anesthesiology Departments in establishing the procedures. The patients' records, surgical descriptions, imaging studies, and histopathological material were reviewed. Among 12 patients presenting with brain tumors, there were neither operative mortality nor fetal deaths. Among the vascular lesions, aneurysm rupture was responsible for bleeding in 6 instances. Arteriovenous malformation was diagnosed in 7 patients. In this subgroup, the maternal and fetal mortality rates were 11.7% and 23.7%, respectively. We can assert that the association between a brain tumor and vascular lesions with pregnancy is a very unusual event, which jeopardizes both the lives of the mother and infant. It remains incompletely characterized due to the rare nature of these potentially devastating events. Knowing the exact mechanism responsible for the interaction of pregnancy and with these lesions will improve the treatment of these patients.

    Full Text Available ABSTRACT Erectile dysfunction (ED is a common complication of pelvic fractures. To identify the vascular and neurogenic factors associated with ED, 120 patients admitted with ED after traumatic pelvic fracture between January 2009 and June 2013 were enrolled in this study. All patients answered the International Index of Erectile Function (IIEF-5 questionnaire. Nocturnal penile tumescence (NPT testing confirmed the occurrence of ED in 96 (80% patients on whom penile duplex ultrasound and neurophysiological testing were further performed. Of these ED patients 29 (30% were demonstrated only with vascular abnormality, 41 (42.7% were detected only with neural abnormality, 26 (27.1% revealed mixed abnormalities. Of the 55 patients (29+26 with vascular problems, 7 patients (12.7% with abnormal arterial response to intracavernous injection of Bimix (15mg papaverine and 1mg phentolamine, 31 (56.4% with corporal veno-occlusive dysfunction and 17 (30.9% had both problems. Of the 67 (41+26 patients with abnormal neurophysiological outcomes, 51 (76.1% with abnormal bulbocavernosus reflex (BCR, 20 (29.9% with pathological pudendal nerve evoked potentials (PDEPs and 25 (37.3% with abnormal posterior tibial somatosensory nerve evoked potentials (PTSSEPs. Our observation indicated that neurogenic factors are important for the generation of ED in patients with pelvic fracture; venous impotence is more common than arteriogenic ED.

    Psychiatric institutions (hospitals and out-patient clinics) are obliged to report cases of suicide to the authorities, but it has not been known to what extent this obligation has been fulfilled. The Norwegian Board of Health Supervision wished to provide an overview of reporting frequencies, descriptions of the extent of the problem, reasons for suicide in patients undergoing psychiatric treatment, whether the institutions use these occurrences to improve the quality of their work and how these cases were handled by the 18 county medical officers. The county medical officers completed registration forms and closing letters for each reported case of suicide committed by patients in psychiatric care (in 2005 and 2006), and sent these documents to the Norwegian Board of Health Supervision. 34/176 (19.3%) suicides were not reported according to the requirements. Almost none of the institutions seemed to use the occurrences in their work to improve quality. There were large differences between the counties both with respect to the number of - and the handling of the reports. The psychiatric hospitals and out-patient clinics must fulfil their obligation to report suicides to the authorities to a larger degree, and to use such occurrences in their work to prevent suicides.

    Poor adherence with growth hormone (GH) therapy has been associated with worse clinical outcomes, which in children relates specifically to their linear growth and loss of quality of life. The "360° GH in Europe" meeting, held in Lisbon, Portugal, in June 2016 and funded by Merck KGaA (Germany), examined many aspects of GH diseases. The three sessions, entitled " Short Stature Diagnosis and Referral ," " Optimizing Patient Management ," and " Managing Transition ," each benefited from three guest speaker presentations, followed by an open discussion and are reported as a manuscript, authored by the speakers. Reported here is a summary of the proceedings of the second session, which reviewed the determinants of GH therapy response, factors affecting GH therapy adherence and the development of innovative technologies to improve GH treatment in children. Response to GH therapy varies widely, particularly in regard to the underlying diagnosis, although there is little consensus on the definition of a poor response. If the growth response is seen to be less than expected, the possible reasons should be discussed with patients and their parents, including compliance with the therapy regimen. Understanding and addressing the multiple factors that influence adherence, in order to optimize GH therapy, requires a multi-disciplinary approach. Because therapy continues over many years, various healthcare professionals will be involved at different periods of the patient's journey. The role of the injection device for GH therapy, frequent monitoring of response, and patient support are all important for maintaining adherence. New injection devices are incorporating electronic technologies for automated monitoring and recording of clinically relevant information on injections. Study results are indicating that such devices can at least maintain GH adherence; however, acceptance of novel devices needs to be assessed and there remains an on-going need for innovations.

    Myelofibrosis (MF) is characterized by bone marrow fibrosis, progressive anemia and extramedullary hematopoiesis, primarily manifested as splenomegaly. Patients also experience debilitating constitutional symptoms, including sequelae of splenomegaly, night sweats and fatigue. Ruxolitinib (INC424, INCB18424, Jakafi, Jakavi), a JAK1 and JAK2 inhibitor, was approved in November 2011 by the US FDA for the treatment of intermediate- or high-risk MF, and more recently in Europe and Canada for the treatment of MF-related splenomegaly or symptoms. These approvals were based on data from two randomized Phase III studies: COMFORT-I randomized against placebo, and COMFORT-II randomized against best available therapy. In these studies, ruxolitinib rapidly improved multiple disease manifestations of MF, reducing splenomegaly and improving quality of life of patients and potentially prolonging survival. However, as with other chemotherapies, ruxolitinib therapy is associated with some adverse events, such as anemia and thrombocytopenia. The aims of this article are to provide a brief overview of ruxolitinib therapy, to discuss some common adverse events associated with ruxolitinib therapy and to provide clinical management recommendations to maximize patients' benefit from ruxolitinib.

    Evidence suggests that there may be drug interactions between antiepileptic drugs and hormonal therapies, which can present a challenge to endocrinologists dealing with patients who have both hypopituitarism and neurological diseases. Data are scarce for this subgroup of patients; however, data for the interaction of antiepileptic drugs with the pituitary axis have shown that chronic use of many antiepileptic drugs, such as carbamazepine, oxcarbazepine, and topiramate, enhances hepatic cytochrome P450 3A4 (CYP3A4) activity, and can decrease serum concentrations of sex hormones. Other antiepileptic drugs increase sex hormone-binding globulin, which reduces the bioactivity of testosterone and estradiol. Additionally, the combined oestrogen-progestagen contraceptive pill might decrease lamotrigine concentrations, which could worsen seizure control. Moreover, sex hormones and their metabolites can directly act on neuronal excitability, acting as neurosteroids. Because carbamazepine and oxcarbazepine can enhance the sensitivity of renal tubules, a reduction in desmopressin dose might be necessary in patients with central diabetes insipidus. Although the effects of antiepileptic drugs in central hypothyroidism have not yet been studied, substantial evidence indicates that several antiepileptic drugs can increase thyroid hormone metabolism. However, although it is reasonable to expect a need for a thyroxine dose increase with some antiepileptic drugs, the effect of excessive thyroxine in lowering seizure threshold should also be considered. There are no reports of significant interactions between antiepileptic drugs and the efficacy of human growth hormone therapy, and few data are available for the effects of second-generation antiepileptic drugs on hypopituitarism treatment.

    Full Text Available Type 2 diabetes has long been known to be associated with an increased risk of cardiovascular disease. Patients with type 2 diabetes have also been shown to benefit more from antihypertensive therapy than do non-diabetics with hypertension. The benefits of aggressive antihypertensive therapy are reflected in the recent reduction of blood pressure (BP targets in international guidelines. Drugs acting on the reninangiotensin-aldosterone system (RAAS have well-documented efficacy, and results from large-scale trials with highly selective angiotensin II (Ang II receptor blockers (ARBs, such as valsartan, are awaited. The VALUE trial will provide the largest body of information yet on the comparative benefits of using an ARB or calcium channel blocker in hypertensive patients with diabetes.

  5. Do stress fractures induce hypertrophy of the grafted fibula? A report of three cases received free vascularized fibular graft treatment for tibial defects.

    2016-06-01

    The presence of large segmental defects of the diaphyseal bone is challenging for orthopedic surgeons. Free vascularized fibular grafting (FVFG) is considered to be a reliable reconstructive procedure. Stress fractures are a common complication following this surgery, and hypertrophy is the main physiological change of the grafted fibula. The exact mechanism of hypertrophy is not completely known. To the best of our knowledge, no studies have examined the possible relationship between stress fractures and hypertrophy. We herein report three cases of patients underwent FVFG. Two of them developed stress fractures and significant hypertrophy, while the remaining patient developed neither stress fractures nor significant hypertrophy. This phenomenon indicates that a relationship may exist between stress fractures and hypertrophy of the grafted fibula, specifically, that the presence of a stress fracture may initiate the process of hypertrophy.

    We evaluated 50 consecutive patients who received thrombolytic therapy for acute myocardial infarction using thallium-201 single photon emission computed tomography in combination with oral dipyridamole to assess the frequency of residual myocardial ischemia. Thallium studies were performed early after myocardial infarction at a mean of 4.6 days. The time from the onset of chest pain to the administration of thrombolytic therapy was 2.6 hours (range 0.5 to 5.5). Q wave myocardial infarction was evident in 46 patients; four patients had a non-Q wave infarction (anterior infarction in 31 patients and inferior infarction in 19 patients). The serum mean peak creatinine kinase was 1503 IU/L (range 127 to 6500). Coronary angiography was performed in all patients at a mean of 3.1 days (range 2 to 10) and revealed the infarct-related vessel to be patent in 36 patients (72%). The ejection fraction was 48% (range 26% to 67%). After dipyridamole administration, 13 patients (26%) developed angina that was easily reversed with the administration of intravenous aminophylline. Systolic blood pressure decreased from 122 to 115 mm Hg (p less than 0.05) and the heart rate increased from 76 to 85 beats/min (p less than 0.05). None of the patients had significant hypotension, arrhythmias, or evidence of infarct extension. Perfusion abnormalities were present on the initial thallium images in 48 patients. Redistribution suggestive of ischemia was present in 36 patients (72%). Ischemia confined to the vascular distribution of the infarct vessel was evident in 22 patients. Seven patients had ischemia in the infarct zone as well as in a remote myocardial segment. Thus 29 patients (58%) had ischemia in the distribution of the infarct vessel. Ischemia in the infarct zone was evident in 19 of 36 patients with open infarct vessels and in 10 of 14 patients with occluded infarct vessels

    To investigate variables before sorafenib therapy on the clinical outcomes in hepatocellular carcinoma (HCC) patients receiving sorafenib and to further assess and compare the predictive performance of continuous parameters using time-dependent receiver operating characteristics (ROC) analysis. A total of 225 HCC patients were analyzed. We retrospectively examined factors related to overall survival (OS) and progression free survival (PFS) using univariate and multivariate analyses. Subsequently, we performed time-dependent ROC analysis of continuous parameters which were significant in the multivariate analysis in terms of OS and PFS. Total sum of area under the ROC in all time points (defined as TAAT score) in each case was calculated. Our cohort included 175 male and 50 female patients (median age, 72 years) and included 158 Child-Pugh A and 67 Child-Pugh B patients. The median OS time was 0.68 years, while the median PFS time was 0.24 years. On multivariate analysis, gender, body mass index (BMI), Child-Pugh classification, extrahepatic metastases, tumor burden, aspartate aminotransferase (AST) and alpha-fetoprotein (AFP) were identified as significant predictors of OS and ECOG-performance status, Child-Pugh classification and extrahepatic metastases were identified as significant predictors of PFS. Among three continuous variables (i.e., BMI, AST and AFP), AFP had the highest TAAT score for the entire cohort. In subgroup analyses, AFP had the highest TAAT score except for Child-Pugh B and female among three continuous variables. In continuous variables, AFP could have higher predictive accuracy for survival in HCC patients undergoing sorafenib therapy.

    2014-01-01

    Peritonitis is a major complication of peritoneal dialysis (PD) and remains the most common cause of PD failure. Micrococci are catalase-positive, coagulase-negative, and gram-positive cocci that are spherical, often found in tetrad, and belong to the family Micrococcaceae. Micrococcus species are commonly found in the environment, and it is now recognized that Micrococcus species can be opportunistic pathogens in immunocompromised patients. The only consistent predisposing factor for Micrococcus infection is an immunocompromised state. We report three cases of Micrococcus PD peritonitis. Improper practice of PD may have been the causative factor. Although Micrococcus species are low-virulence pathogens, infection could result in refractory peritonitis and subsequent PD failure. Intraperitoneal administration of vancomycin for at least 2 weeks is recommended for Micrococcus peritonitis.

    Radioimmunologic assays of blood serum carcinoembryonic antigen (CEA) level were conducted at major stages of treatment of gastric cancer by subtotal stomach resection and gastrectomy with preliminary cryotreatment and thawing of tumor. A short-term rise in CEA level occurred in 53.9 % of cases 3-4 days after combined therapy. A decrease in CEA concentration at discharge from hospital as compared with preoperative level and that registered 3-4 days after operation was observed in 50 and 75 % of cases of combined therapy, respectively, and 47.5 and 37.5 % of controls (surgery without cryotreatment). There was nocorrelation between cryotreatment and changes in CEA level in gastric ulcer patients

    Effective use of warfarin involves keeping the international normalised ratio (INR) within a relatively narrow therapeutic range. However, patients respond widely to their dose of warfarin. Overcoagulation can lead to an increased risk of excessive bleeding, while undercoagulation can lead to increased clot formation. There is some evidence that patients with a variable response to warfarin may benefit from a concomitant low dose of vitamin K. To assess the effects of concomitant supplementation of low-dose oral vitamin K for anticoagulation control in patients being initiated on or taking a maintenance dose of warfarin. To identify previous reviews, we searched the Database of Abstracts of Reviews of Effects (DARE via The Cochrane Library, Wiley) (Issue 2, 2011). To identify primary studies, we searched the Cochrane Central Register of Controlled Trials (CENTRAL via The Cochrane Library, Wiley) (Issue 2, 2014), Ovid MEDLINE (R) In-Process & Other Non-Indexed Citations database and Ovid MEDLINE (R) (OvidSP) (1946 to 25 February 2014), Embase (OvidSP) (1974 to week 8 of 2014), Science Citation Index Expanded™ & Conference Proceedings Citation Index - Science (Web of Science™) (1945 to 27 February 2014), and the NHS Economics Evaluations Database (NHS EED) (via The Cochrane Library, Wiley) (Issue 2, 2014). We did not apply any language or date restrictions. We used additional methods to identify grey literature and ongoing studies. Randomised controlled trials comparing the addition of vitamin K versus placebo in patients initiating warfarin or already taking warfarin. Two review authors independently selected and extracted data from included studies. When disagreement arose, a third author helped reached a consensus. We also assessed risk of bias. We identified two studies with a total of 100 participants for inclusion in the review. We found the overall risk of bias to be unclear in a number of domains. Neither study reported the time taken to the first INR in

    Although postoperative readmissions are frequent in vascular surgery patients, the reasons for these readmissions are not well characterized, and effective approaches to their reduction are unknown. Our aim was to analyze the reasons for vascular surgery readmissions and to report potential areas for focused efforts aimed at readmission reduction. The 2012 to 2013 American College of Surgeons National Quality Improvement Program (ACS NSQIP) data set was queried for vascular surgery patients. Multivariable models were developed to analyze risk factors for postdischarge infections, the major drivers of unplanned 30-day readmissions. We identified 86,403 vascular surgery patients for analysis. Thirty-day readmission occurred in 8827 (10%), of which 8054 (91%) were unplanned. Of the unplanned readmissions, 61% (n = 4951) were related to the index vascular surgery procedure. Infectious complications were the most common reason for a surgery-related readmission (1940 [39%]), with surgical site infection being the most common type of infection related to unplanned readmission. Multivariable analysis showed the top five preoperative risk factors for postdischarge infections were the presence of a preoperative open wound, inpatient operation, obesity, work relative value unit, and insulin-dependent diabetes (but not diabetes managed with oral medications). Cigarette smoking was a weak predictor and came in tenth in the mode (overall C index, 0.657). When operative and postoperative factors were included in the model, total operative time was the strongest predictor of postdischarge infectious complications (odds ratio [OR] 1.2 for each 1-hour increase in operative time), followed by presence of a preoperative open wound (OR, 1.5), inpatient operation (OR, 2), obesity (OR, 1.8), and discharge to rehabilitation facility (OR, 1.7; P model was fair (C statistic, 0.686). Infectious complications dominate the reasons for unplanned 30-day readmissions in vascular surgery

    Prior studies show significant gaps in the informed decision-making process, a central goal of surgical care. These studies have been limited by their focus on low-risk decisions, single visits rather than entire consultations, or both. Our objectives were, first, to rate informed decision-making for major elective vascular surgery based on audiotapes of actual physician-patient conversations and, second, to compare ratings of informed decision-making for first visits to ratings for multiple visits by the same patient over time. We prospectively enrolled patients for whom vascular surgical treatment was a potential option at a tertiary care outpatient vascular surgery clinic. We audio-taped all surgeon-patient conversations, including multiple visits when necessary, until a decision was made. Using an existing method, we evaluated the transcripts for elements of decision-making, including basic elements (e.g., an explanation of the clinical condition), intermediate elements (e.g., risks and benefits) and complex elements (e.g., uncertainty around the decision). We analyzed 145 surgeon-patient consultations. Overall, 45% of consultations contained complex elements, whereas 23% did not contain the basic elements of decision-making. For the 67 consultations that involved multiple visits, ratings were significantly higher when evaluating all visits (50% complex elements) compared with evaluating only the first visit (33% complex elements, p decision-making over multiple visits yielded different results than analyzing decision-making for single visits.

    Depression is believed to be a common side effect in patients receiving beta-blocker therapy. However, diagnoses of depression defined by current diagnostic criteria may not be more common in patients receiving beta-blockers than in patients with the same medical disorder receiving other medications. Seventy-seven patients undergoing elective cardiac catheterization for evaluation of chest pain received a semi-structured diagnostic psychiatric interview. Twenty-one percent of the patients receiving beta-blockers and 33 percent of the patients receiving medications other than beta-blockers met the current American Psychiatric Association criteria for major depressive disorder (DSM-III) (p = NS). The mean heart rate and state anxiety scores for patients taking beta-blockers were significantly lower than those measured in patients taking medications other than beta-blockers. No other medical or demographic differences were observed between the two groups. Despite the methodologic limitations of the study, there does not appear to be a difference in the point prevalence of depression between patients receiving beta-blockers and those receiving other medications.

    Purpose To ascertain whether single nucleotide polymorphisms (SNPs) in the Vascular Endothelial Growth factor (VEGFA), Complement Factor H (CFH), and LOC387715 genes could predict outcome to anti-VEGF therapy for patients with age related macular degeneration (AMD). Methods Patients with “wet” AMD were identified by chart review. Baseline optical coherence tomography (OCT) and visual acuity (VA) data, and at least 6 months of clinical follow up after 3 initial monthly injections of bevacizumab or ranibizumab were required for inclusion. Based on OCT and VA, patients were categorized into two possible clinical outcomes: (a) responders and (b) non-responders. DNA was extracted from saliva and genotyped for candidate SNPs in the VEGFA, LOC387715, and CFH genes. Clinical outcomes were statistically compared to patient genotypes. Results 101 patients were recruited, and one eye from each patient was included in the analysis. 97% of samples were successfully genotyped for all SNPs. We found a statistically significant association between the LOC387715 A69S TT genotype and outcome based on OCT. Conclusion Genetic variation may be associated with outcome in patients receiving anti-VEGF therapy. PMID:24143065

    1987-01-01

    Dipyridamole-thallium imaging has been suggested as a method of preoperatively assessing cardiac risk in patients undergoing major surgery. To define more clearly its proper role in preoperative assessment, we prospectively evaluated 111 patients undergoing vascular surgery. In the first set of 61 patients, our data confirmed the value of preoperative dipyridamole-thallium scanning in identifying the patients who suffered postoperative ischemic events. Events occurred in eight of 18 patients with reversible defects on preoperative imaging, compared with no events in 43 patients with no thallium redistribution (confidence interval for the risk difference: 0.624, 0.256). The results also suggested that clinical factors might allow identification of a low-risk subset of patients. To test the hypothesis that patients with no evidence of congestive heart failure, angina, prior myocardial infarction, or diabetes do not require further preoperative testing, we evaluated an additional 50 patients having vascular procedures. None of the 23 without the clinical markers had untoward outcomes, while ten of 27 patients with one or more of these clinical markers suffered postoperative ischemic events (confidence interval for the risk difference: 0.592, 0.148). In the clinical high-risk subset, further risk stratification is achieved with dipyridamole-thallium scanning

    Totally implantable vascular access devices (TIVADs) are widely used to administer chemotherapy to cancer patients. While great progress has been made with respect to breast surgical reconstruction to take into account both aesthetics and patients' perceptions of body integrity, these aspects have not been considered with regard to the impact of TIVAD. In order to address this practice gap, we have adapted our TIVAD implantation technique to improve cosmetic results. The aim of this study was to assess breast cancer patients' comfort level and aesthetic satisfaction with regard to TIVAD insertion. Patients with breast cancer admitted for chemotherapy at an outpatient clinic completed a previously validated survey evaluating three main domains: symptoms (pain, discomfort) related to the TIVAD itself in daily activity, information received before and during the surgical procedure, and cosmetic aspects regarding the port insertion site (scar, port, and catheter location). Between September 2010 and June 2011, 232 patients were evaluated. Cosmetic satisfaction with scar location was high (93.3 %). Information given to patients before and during the procedure had a major impact on both symptom perception in daily activity and on cosmetic satisfaction. Obtaining a more aesthetic scar by placing the TIVAD in the deltopectoral groove contributed to a high rate of cosmetic satisfaction. Furthermore, the relevance of information given to patients before and/or during surgery had a major impact on symptom perception. Therefore, we suggest including a pre-operative information session in the care pathway.

    Cryptococcal infections are responsible for significant morbidity and mortality in immunocompromised patients. Reports of these infections in patients on small molecular kinase inhibitors have not been widely reported in clinical trials. We describe one case of cryptococcal meningoencephalitis and one case of cryptococcal pneumonia in two patients who were receiving ibrutinib for chronic lymphocytic leukemia. Despite different sites of cryptococcal infection, both patients had similar presentations of acute illness. Patient 1 was worked up for health care-associated pneumonia, as well as acute sinusitis prior to the diagnosis of cryptococcal meningoencephalitis. He also had a more complex past medical history than patient 2. Patient 2 developed atrial fibrillation from ibrutinib prior to admission for presumed health care-associated pneumonia. Cryptococcal antigen testing was done sooner in this patient due to patient receiving high-dose steroids for the treatment of underlying hemolytic anemia. We conclude that patients who develop acute illness while receiving ibrutinib should be considered for cryptococcal antigen testing.

    Full Text Available It has recently been shown that vascular endothelial growth factor (VEGF enhances vascular permeability and that mast cells produce VEGF, suggesting the involvement of VEGF in allergic diseases. In the present study we quantitatively analyzed VEGF in the nasal lavage fluid of patients with nasal allergy. We performed nasal antigen challenge with Japanese cedar pollen antigen in 10 healthy adult volunteers and in 10 cedar pollen IgE-positive patients with nasal allergy. In all patients with nasal allergy, VEGF and histamine levels in the nasal lavage fluid reached a peak 30 min after antigen challenge, then returned to prechallenge values 2 h after antigen challenge. In these patients, the histamine level increased three-fold, while the VEGF level increased 10-fold. However, in all healthy adult volunteers, VEGF and histamine levels did not increase. A stronger correlation was noted between the ratio of decreased nasal cavity volume and the ratio of increased VEGF levels (R = 0.823; P < 0.001 than between the ratio of nasal cavity volume and the ratio of increased histamine levels (R = 0.660; P < 0.01. These results suggest that VEGF may contribute to the pathogenesis of nasal obstruction in the early phase of nasal allergy as a new factor involved in increasing vascular permeability.

    1982-01-01

    A retrospective analysis was done of 106 patients who received radiation therapy for brain metastasis. Dexamethasone therapy was instituted in 97 patients. Peptic ulcer disease developed in 5 of 89 patients (5.6 percent) who received a dosage of at least 12 mg a day, but did not occur in patients who received a lower dose or in those who did not receive steroids. The interval between institution of dexamethasone therapy and the development of peptic ulcer disease ranged from three to nine weeks. Two patients had perforated ulcers, one of whom required surgical resection. Peptic ulcer disease contributed to the general deterioration and death of three of the five patients. Overall, in 14 of the 89 patients (15.7 percent) a complication of steroid therapy developed in the form of peptic ulcer disease, steroid myopathy or diabetes mellitus (or a combination of these)

    There is variability in physician practice regarding delivery method and timeliness of test results to cancer patients. Our aim was to survey patients to determine if there was a difference between actual and preferred care for disclosure of test results. A de-identified survey was distributed to online cancer support groups to query patients about their experience regarding communication of cancer testing and timeliness. Analyses of the differences between actual and preferred communication and wait times were performed. Overall, 1000 patients completed the survey. The analysis herein was restricted to 784 breast cancer survivors. Survey responders were predominately White (non-Hispanic; 89 %), college educated (78 %), and media 'savvy' (online medical media usage; 97 %). Differences between actual and preferred care were identified for the domains of mode of communication and wait times for initial breast cancer diagnostic biopsies and other tests. A total of 309 (39 %) of 784 patients received face-to-face communication for a new cancer diagnosis, with 394 (50 %) patients preferring this option (p cancer biopsy result within 2 days, with 646 (82 %) patients preferring this option (p < 0.0001). Differences were also identified between actual and preferred care for multiple other test types. Actual care for timeliness and modes of communication did not reflect patient-desired care. National and local initiatives to improve performance are needed. As a first step, we recommend that each patient be queried about their preference for mode of communication and timeliness, and efforts made to comply.

    Vascular tortuosity syndrome is a rare genetic disorder that causes tortuosity and stenosis of the pulmonary, systemic and / or coronary circulations. As a result of treatment of pulmonary stenosis, symptoms of pulmonary edema, known as lung reperfusion syndrome, may occur. The case is presented of an adolescent patient with vascular tortuosity syndrome who presented with a pulmonary reperfusion syndrome after multiple stent implants in the left pulmonary artery. After the procedure, the patient immediately developed an acute pulmonary edema with severe clinical deterioration, which required assistance with extracorporeal membrane oxygenation for recovery.

    ABSTRACT. There is limited evidence about the progression of cognitive performance during the post-stroke stage. Objective: To assess the evolution of cognitive performance in stroke patients without vascular cognitive impairment (VCI), patients with vascular mild cognitive impairment (MCI), and patients with vascular dementia (VD). Methods: A prospective cohort of stroke outpatients from two secondary medical centers in Lima, Peru was studied. We performed standardized evaluations at definitive diagnosis (baseline evaluation), and control follow-ups at 6 and 12 months, including a battery of short cognitive tests: Clinical Dementia Rating (CDR), Addenbrooke's Cognitive Examination (ACE), and INECO Frontal Screening (IFS). Results: 152 outpatients completed the follow-up, showing progressive increase in mean score on the CDR(0.34 to 0.46), contrary to the pattern observed on the ACE and IFS (78.18 to 76.48 and 23.63 to 22.24). The box plot for the CDR test showed that VCI patients had progressive worsening (0.79 to 0.16). Conversely, this trend was not observed in subjects without VCI. The box plot for the ACE and IFS showed that, for the majority of the differentiated stroke types, both non-VCI and VCI patients had progressive worsening. Conclusion: According to both ACE and IFS results during a 1-year follow-up, the cognitive performance of stroke patients worsened, a trend which was particularly consistent in infarction-type stroke patients.

    Full Text Available This study aimed to explore linkages of patients' social network composition with health behaviors and clinical risk factors.This observational study was embedded in a project aimed at improving cardiovascular risk management (CRVM in primary care. 657 vascular patients (227 with cardiovascular disease, 380 at high vascular risk, mean age 72.4 (SD 9.4 years, were recruited as were individuals patients considered important for dealing with their disease, so called alters (n = 487. Network composition was measured with structured patient questionnaires. Both patients and alters completed questionnaires to measure health behavior (habits for physical activity, diet, and smoking. Clinical risk factors (systolic blood pressure, LDL cholesterol level, and body mass index were extracted from patients' medical records. Six logistic regression analyses, using generalized estimating equations, were used to test three hypothesized effects of network composition (having alters with healthful behaviors, without depression, and with specialized knowledge on six outcomes, adjusted for demographic, personal and psychological characteristics.Having alters with overall healthful behavior was related to healthful patient diet (OR 2.14, 95%CI: 1.52-3.02. Having non-smoking alters in networks was related to reduced odds for patient smoking (OR 0.17, 95%CI: 0.05-0.60. No effects of presence of non-depressed alters were found. Presence of alters with specialized knowledge on CVRM was inversely related to healthful diet habits of patients (OR 0.47, 95%CI 0.24-0.89. No significant associations between social network composition and clinical risk factors were found.Diet and smoking, but not physical exercise and clinical risk factors, were associated with social network composition of patients with vascular conditions. In this study of vascular patients, controlling for both personal and psychological factors, fewer network influences were found compared to previous

    The paper deals with the results of observations over 62 patients (55 females and 7 males) from the age of 42-76 with climacteric spondilopathy. The following syndromes of the nervous system lesions were revealed: neuralgic syndrome, middle and lower thoracal radiculoneuritis, the syndrome of vegetative sympatoganglionitis, myelopathy. Special attetion was given to the specificity of the nervous system lesions in patients with climacteric spondilopathy which was characterized by a tendency to vegetative-visceral crises. The author recommends a scheme of a comprehensive treatment of patients with climacteric spondilopathy with vegetative-vascular and visceral crises. This treatment includes androgen-estrogen preparations, anabolic steroids, thyrocalcitonine and symptomatic treatment.

    The incidence of arterial disease increases with age. Increasing life expectancy in the western world will intensify demands on vascular surgeons with regard to increasing caseload, expanding patient selection criteria, and more complex and minimally-invasive treatment options. We analysed our arterial cases over the past 31 years (n = 6,144) and compared our methods of intervention and complication rates in the elderly population (>75) with the younger cohort, in order to determine whether age should influence our management strategies.

    The aim of this study was to assess pulmonary vascular resistance (PVR) in patients with pulmonary fibrosis (PF) by phase-contrast magnetic resonance imaging (MRI). Subjects were 11 healthy volunteers and 11 patients with PF. Using phase-contrast MRI, we measured pulmonary arterial blood flow and calculated the parameters of PVR. Parameters were compared between volunteers and patients using unpaired t-tests. The diagnostic capability of the parameters was evaluated by receiver operating characteristic (ROC) curve analysis. Patients underwent respiratory function tests (RFTs) and chest computed tomography (CT), and they were correlated with MRI parameters. Most MRI parameters were significantly different between volunteers and patients (t-test P values were <0.05 in 9 of 10 parameters). Regarding the RFT and CT visual score, only the %DLco/VA and acceleration time and the CT visual score and average flow volume had significant correlation [r=-0.667 (P=0.024) and r=-0.6 (P=0.031)], respectively. Our findings suggest that PVR derived from phase-contrast MRI is significantly higher in patients with PF than in volunteers. However, all but two of these parameters may not correlate with the severity of PF. (author)

    Immune state of 272 clean-up workers, participants of the Chernobyl Power Plant accident, suffering from vegeto-vascular dystonia is studied. Comparison groups were formed by 20 healthy clean-up workers, 25 vegeto-vascular dystonia patients non-participating in the clean-up works, and 60 healthy donors. Immune state disturbances in the vegeto-vascular dystonia patients have unidirectional changing but among the clear-up workers their expression was much significant coinciding with the more severe clinical courses of disease comparing to the patients non-participating in the clean-up works

    Full Text Available Paradoxical embolism resulting in cryptogenic stroke has received much attention recently, with the primary focus on patent foramen ovale (PFO. However, it is essential to be vigilant in the search for other causes of paradoxical embolic events, such as pulmonary arteriovenous malformations (PAVM. We describe successful closure of pulmonary AVM with a St Jude Medical (Plymouth, MN Amplatzer TM vascular plug IV. The newer AVP-IV devices can be used for successful embolization of tortuous pulmonary AVM in remote locations where use of other traditional devices may be technically challenging.

    • BACKGROUND: The prevalence of carotid artery stenosis (CAS in the  eneral population is not high enough to justify screening programs. This study was done to determine the prevalence of asymptomatic carotid artery stenosis (ACAS among patients with severe peripheral vascular disease (PVD.
    • METHODS: Between March 2005 and February 2006, 54 consecutive  atients with severe PVD admitted at a vascular surgery unit and underwent carotid duplex scanning in a prospective study. A  uestionnaire was used to collect data concerning known risk factors. Significant CAS was defined as a stenosis of 70% or greater.
    • RESULTS: The mean age was 62.5 years (51-72. Out of 54 patients, 2 (3.7% had an occluded internal carotid artery. Significant CAS was found in 9 (16.7% and its presence was correlated with diabetes, hypertension, hypercholesterolemia, hypertriglyceridemia, coronary artery disease, severity of symptoms, ankle-brachial index, and carotid bruit. On multivariate analysis, only hypercholesterolemia and carotid bruit seemed to have independent influence.
    • CONCLUSION: The prevalence of significant ACAS is higher among  atients with severe PVD. This patient population may indicate a  uitable subgroup for screening of ACAS, especially when hypercholesterolemia and carotid bruit are present.

    Full Text Available Vascular access stenosis is a major complication in hemodialysis patients. We prospectively observed 50 patients in whom 50 nitinol shape-memory alloy-recoverable technology (SMART stents were used as salvage therapy for recurrent peripheral venous stenosis. Twenty-five stents each were deployed in native arteriovenous fistula (AVF and synthetic arteriovenous polyurethane graft (AVG cases. Vascular access patency rates were calculated by Kaplan-Meier analysis. The primary patency rates in AVF versus AVG at 3, 6, and 12 months were 80.3% versus 75.6%, 64.9% versus 28.3%, and 32.3% versus 18.9%, respectively. The secondary patency rates in AVF versus AVG at 3, 6, and 12 months were 88.5% versus 75.5%, 82.6% versus 61.8%, and 74.4% versus 61.8%, respectively. Although there were no statistically significant difference in patency between AVF and AVG, AVG showed poor tendency in primary and secondary patency. The usefulness of SMART stents was limited in a short period of time in hemodialysis patients with recurrent vascular access stenosis.

    Stimulation to bronchial mucosa is one of the major risk factor of asthma attack. When patients receive surgical intervention and general anesthesia, they are always exposed to stimulation to bronchial mucosa. Prevention method of bronchial asthma attack during surgical intervention is not established yet. We investigated that clinical course of patients with bronchial asthma who received general anesthesia and surgical intervention. Seventy-six patients with bronchial asthma were received general anesthesia and surgical intervention from 1993 to 1998. Twenty-four patients were mild asthmatic patients, 39 were moderate asthmatic patients and 13 were severe asthmatic patients. Preoperative treatment for preventing asthma attack was as follows; Eight patients were given intravenous infusion of aminophylline before operation. Fifty-two patients were given intravenous infusion of aminophylline and hydrocortisone before operation. Three patients were given intravenous infusion of hydrocortisone for consecutive 3 days before operation. Thirteen patients were given no treatment for preventing asthma attack. One patient was suffered from asthma attack during operation. She was given no preventing treatment for asthma attack before operation. Three patients were suffered from asthma attack after operation. No wound dehiscence was observed in all patients. To prevent asthma attack during operation, intravenous infusion of steroid before operation is recommended, when patients with asthma receive general anesthesia and surgical intervention.

    In many countries, GPs and home care nurses are involved in care for patients with advanced cancer. Given the varied and complex needs of these patients, providing satisfactory care is a major challenge for them. We therefore aimed to study which aspects of care patients, GPs and home care nurses consider important and whether patients receive these aspects. Seventy-two Dutch patients with advanced cancer, 87 GPs and 26 home care nurses rated the importance of support when experiencing symptoms, respect for patients' autonomy and information provision. Patients also rated whether they received these aspects. Questionnaires were based on the CQ index palliative care. Almost all patients rated information provision and respect for their autonomy as important. The majority also rated support when suffering from specific symptoms as important, especially support when in pain. In general, patients received the care they considered important. However, 49% of those who considered it important to receive support when suffering from fatigue and 23% of those who wanted to receive information on the expected course of their illness did not receive this or only did so sometimes. For most patients with advanced cancer, the palliative care that they receive matches what they consider important. Support for patients experiencing fatigue may need more attention. When symptoms are difficult to control, GPs and nurses may still provide emotional support and practical advice. Furthermore, we recommend that GPs discuss patients' need for information about the expected course of their illness.

    Full Text Available Abstract Background Patients in neurologic in-patient rehabilitation are at risk of cardio- and cerebrovascular events. Microalbuminuria (MAU is frequent and an important risk predictor but has not been validated in in-patient rehabilitation. We therefore aimed to examine MAU as an indicator of risk and predictor of vascular events in a prospective study. Methods The INSIGHT (INvestigation of patients with ischemic Stroke In neuroloGic reHabiliTation registry is the first to provide large scale data on 1,167 patients with acute stroke (χ2 or Mann–Whitney-U Test. Relative risks (RR with 95% confidence intervals (CI were estimated using log-binominal models. To evaluate the association between MAU and new vascular events as well as mortality, we calculated hazard ratios (HR using Cox proportional hazard regression. Results A substantial proportion of patients was MAU positive at baseline (33.1%. Upon univariate analysis these patients were about 4 years older (69 vs. 65 years; p 2; p = 0.03 and increased waist circumference (79.5 vs. 50.4% for women [p  Conclusions INSIGHT demonstrated a significant association between MAU and polyvascular disease and further supports previous findings that MAU predicts cardio-/cerebrovascular events in patients recovering from ischemic stroke. This biomarker may also be used in patients during neurologic in-patient rehabilitation, opening a window of opportunity for early intervention in this patient group at increased risk for recurrent events.

    Objective: To explore the relationship of vascular endothelial marker and endothelium-dependent vasodilatation in patients with essential hypertension (EH). Methods: Plasma endothlium (ET-1) (with RIA) and von Willber factor (vWF)(with ELISA) levels were measured both before and after 12 wks' treatment in 56 patients with essential hypertension and 32 controls. The brachial artery endothelium-dependent vasodilatation function was examined with high resolving color doppler ultra-sonography. The 56 patients with EH were of two groups A. high and very high risk, n=26 B. low and moderate risk, n=30. Results: Plasma levels of ET-1, vWF in patients with EH as a whole were significantly higher than those in controls group [(53.3±16.2)pg/ml vs(42.5±8.5)pg/ml, (158.2±28.6)% vs(130.6±35.2)%], endothelium-dependent vasodilatation function wasmuch reduced in patients with EH(7.5±4.2)% vs controls(12.3±4.3)%. Among the patients, values in Group A were significantly different from those in Group B. After treatment for 12 weeks, plasma ET-1 and vWF and endothelium-dependent vasodilatation function were significantly improved. There was negative correlation between vascular endothelial marker levels and endothelium-dependent vasodilatation function. Conclusion: The endothelium-dependent vasodilatation function was impaired and plasma ET-1 and vWF levels were increased in patients with EH, the endothelial dysfunction was closely associated with the risk level of EH. Vascular endothelial markers were useful indicators for evaluation of the endothelium-dependent vasodilatation function. (authors)

    Purpose: To assess toxicity in patients with either a collagen vascular disease (CVD) or multiple sclerosis (MS) treated with intracranial radiosurgery. Methods and Materials: Between January 2004 and April 2009, 6 patients with MS and 14 patients with a CVD were treated with Gamma Knife radiosurgery (GKRS) for intracranial tumors. Treated lesions included 15 total brain metastases in 7 patients, 11 benign brain tumors, 1 low grade glioma, and 1 cavernous malformation. Toxicities were graded by the Radiation Therapy Oncology Group Acute/Late Radiation Morbidity Scoring Criteria. “Rare toxicities” were characterized as those reported in the scientific literature at an incidence of 3 (range, 0.14–7.8 cm 3 ). Of the 14 patients with CVD, none experienced a Grade 3 or 4 toxicity or a toxicity characterized as rare. Of the 6 patients with MS, 3 experienced rare toxicities, and two of these were Grade 3 toxicities. Rare complications included a patient experiencing both communicating hydrocephalus and facial nerve palsy, as well as 2 additional patients with motor cranial nerve palsy. High-grade toxicities included the patient with an acoustic neuroma requiring ventriculoperitoneal shunt placement for obstructive hydrocephalus, and 1 patient with a facial nerve schwannoma who experienced permanent facial nerve palsy. Interval between radiosurgery and high-grade toxicities ranged from 1 week to 4 months. Conclusions: Our series suggests that patients with MS who receive GKRS may be at increased risk of rare and high-grade treatment-related toxicity. Given the time course of toxicity, treatment-related edema or demyelination represent potential mechanisms.

    Background and purpose Functional magnetic resonance imaging (fMRI) is a non-invasive pre-surgical tool used to assess localization and lateralization of language function in brain tumor and vascular lesion patients in order to guide neurosurgeons as they devise a surgical approach to treat these lesions. We investigated the effect of varying the statistical thresholds as well as the type of language tasks on functional activation patterns and language lateralization. We hypothesized that language lateralization indices (LIs) would be threshold- and task-dependent. Materials and methods Imaging data were collected from brain tumor patients (n = 67, average age 48 years) and vascular lesion patients (n = 25, average age 43 years) who received pre-operative fMRI scanning. Both patient groups performed expressive (antonym and/or letter-word generation) and receptive (tumor patients performed text-reading; vascular lesion patients performed text-listening) language tasks. A control group (n = 25, average age 45 years) performed the letter-word generation task. Results Brain tumor patients showed left-lateralization during the antonym-word generation and text-reading tasks at high threshold values and bilateral activation during the letter-word generation task, irrespective of the threshold values. Vascular lesion patients showed left-lateralization during the antonym and letter-word generation, and text-listening tasks at high threshold values. Conclusion Our results suggest that the type of task and the applied statistical threshold influence LI and that the threshold effects on LI may be task-specific. Thus identifying critical functional regions and computing LIs should be conducted on an individual subject basis, using a continuum of threshold values with different tasks to provide the most accurate information for surgical planning to minimize post-operative language deficits.

    Vascular groin wounds have higher than expected surgical site infection (SSI) rates and some patients are at enhanced risk. The Wiseman et al. paper suggests an objective scoring system that identifies patients at enhanced risk of postdischarge SSI. We hypothesize that prophylactic groin wound vacuum-assisted closure (VAC) therapy in enhanced risk patients will decrease SSI and readmission and the Wiseman model provides potential evidence that enhanced risk patients can be objectively identified. A single institution, retrospective analysis was conducted from January 2013 to September 2016 utilizing procedure codes to identify patients with wound VACs placed in the operating room. Two distinct groups were identified. The first was a wound complication patient group with 15 limbs (13 patients) with a groin wound VAC placed within 45 days postoperatively for groin wound complications. Eleven of these limbs had the VAC placed at readmission. The second group was a prophylactic patient group that included 8 limbs (7 patients) who received a VAC prophylactically placed in the enhanced risk wounds. These wounds were determined to be enhanced risk based on clinical criteria judged by the operating surgeon such as a large overhanging panniculus and/or one of several ongoing medical issues. We calculated a Wiseman score for all patients, determined total cost of the readmissions, and determined 30-day postsurgical SSI incidence for the prophylactic VAC group. Per the Wiseman scores, 9 limbs with postoperative complications were high risk and 3 limbs were moderate/high risk. Eleven limbs had a VAC placed at readmission with an average readmission cost of $8876.77. For the prophylactic group, 8 limbs were high risk with no observed postdischarge SSI in the first 30 days from surgery. The Wiseman scores showed close correlation between the retrospective high and moderate/high risk groups versus the prophylactic VAC group (31.5 ± 7.3 vs. 32 ± 5.5, P = 0.87). The Wiseman

    We aim to assess serum sodium and potassium levels in patients with different types of cerebro-vascular accidents (CVA) in comparison to control group. A comparative cross-sectional study conducted on patients admitted to the emergency department from January to August 2012. Control group consisted of patients admitted to emergency department due to common cold, urinary tract infection, low back pain, cluster, and tension headache or migraine. Serum sodium and potassium levels were measured via standard laboratory methods. There were 77 patients in control group and 78 in CVA group. Forty nine patients from the CVA group had ischemic CVA, 11 had hemorrhagic CVA and 18 suffered a transient ischemic attack (TIA). Serum sodium level in control group was significantly lower than in patients with TIA, ischemic CVA, and hemorrhagic CVA (P < 0.001). Serum potassium level in control group was higher than patients with TIA, ischemic CVA, and hemorrhagic CVA (P < 0.001). Patients with hemorrhagic CVA showed significantly lower serum potassium level than patients with TIA and ischemic CVA (P < 0.001). Correspondingly, it was observed that serum sodium to potassium ratio was higher in patients with TIA, ischemic CVA, and hemorrhagic CVA (P < 0.001). In patients with hemorrhagic CVA serum sodium to potassium ratio was higher when compared to patients with TIA and ischemic CVA (P < 0.001). This study shows that higher serum sodium and lower serum potassium level may be associated with higher incidence of CVA. Further studies are paramount to elucidate the role of serum electrolyte levels in vascular events.

    To describe the imaging findings (MR imaging and angiography) of high-flow vascular anomalies of the tongue, hemangiomas and arteriovenous malformations (AVMs), with emphasis on the discrepant imaging findings in lingual AVMs. Retrospective review of clinical records, histologic reports and imaging studies of five consecutive patients with high-flow lingual vascular anomalies. One patient had hemangioma (aged 1 month) and four patients had AVMs (aged 15 months, 6, 24, and 33 years). Diagnosis was made on the basis of histology in four lesions and was based on typical clinical history in one lesion. MR imaging and angiographic findings of the hemangioma were typical, but similar findings of focal hyperintense mass on T2-weighted images and angiographic stain were seen in three AVMs (patients aged 15 months, 6 and 33 years). On angiography, there was no nidus or direct arteriovenous (AV) shunting in one AVM (patient aged 15 months). The fourth AVM had typical MR imaging and angiographic findings. The imaging findings in lingual AVMs can be atypical or inconclusive and can mimic hemangiomas, especially in the young patient. Since treatment depends on accurate diagnosis, biopsy may be necessary for lesions with inconclusive imaging findings. (orig.)

    Full Text Available The association between dental and cardio-vascular diseases is essential as both are highly prevalent. Finding a possible causal relation between cardiovascular disease and chronic periodontal pathology, known to cause tooth loss, is therefore essential. The existence of some risk factors, such as smoking, bacterial infections, malnutrition and nutritional deficiencies, may explain the associations observed between cardio-vascular and oral pathologies. In the case of dental diseases, acceleration of atherosclerosis is supported by the role played by infections. The study – performed between 2008-2009 – analyzed 45 cases, selected from the patients hospitalized in the Medical Clinics of the Military Hospital of Ia[i. The patients included in the study suffered from arterial hypertension (HTA, cardiac insufficiency, ischemic cardiopathy, pectoral angina and subacute infectious endocarditis. All were subjected to a stomatological examination, for establishing their dental hygiene, the stomatological diseases they had had and the treatments performed. There are several ways in which infections of the oral cavity lead to cardiovascular disease. These include: transitory bacteriemia; inflammation and vascular lesions; diet and smoking.

    Several genetic markers are related to incidence of cardiovascular events. We evaluated whether a genetic risk score (GRS) based on 30 single-nucleotide-polymorphisms associated with coronary artery disease (CAD) can improve prediction of 10-year risk of new cardiovascular events in patients with clinical manifest vascular disease. In 5742 patients with symptomatic vascular disease enrolled in the SMART study, we developed Cox regression models based on the SMART Risk Score (SRS) and based on the SRS plus the GRS in all patients, in patients with a history of acute arterial thrombotic events and in patients with a history of more stable atherosclerosis and without CAD. The discriminatory ability was expressed by the c-statistic. Model calibration was evaluated by calibration plots. The incremental value of adding the GRS was assessed by net reclassification index (NRI) and decision curve analysis. During a median follow-up of 6.5 years (IQR4.0-9.5), the composite outcome of myocardial infarction, stroke, or vascular death occurred in 933 patients. Hazard ratios of GRS ranging from 0.86 to 1.35 were observed. The discriminatory capacity of the SRS for prediction of 10-year risk of cardiovascular events was fairly good (c-statistic 0.70, 95%CI 0.68-0.72), similar to the model based on the SRS plus the GRS. Calibration of the models based on SRS and SRS plus GRS was adequate. No increase in c-statistics, categorical NRIs and decision curves was observed when adding the GRS. The continuous NRI improved only in patients with stable atherosclerosis (0.14, 95%CI 0.03-0.25), increasing further excluding patients with a history of CAD (0.21, 95%CI 0.06-0.36). In patients with symptomatic vascular disease, a GRS did not improve risk prediction of 10-year risk of cardiovascular events beyond clinical characteristics. The GRS might improve risk prediction of first vascular events in the subgroup of patients with a history of stable atherosclerosis. Copyright © 2015 Elsevier

    Pediatric patients who are receiving parenteral nutrition (PN) unsupplemented with trace minerals can become deficient. Due to shortages in trace mineral products and the 2004 American Society for Parenteral and Enteral Nutrition report stating that individualized trace element supplementation may be warranted, a review was conducted concerning the trace minerals selenium (Se), manganese (Mn), and iodine (I). A retrospective review of pediatric patients receiving PN that contained Se and Mn was conducted to determine if a difference existed between them and patients receiving PN without Se and Mn. Statistical analysis was done to assess a difference between trace mineral levels and the time to deficiency between supplemented and unsupplemented patients. Unsupplemented I patients had urine I levels assessed to determine deficiencies in patients receiving PN. Plasma Se levels were measured at a mean of 20 days for supplemented patients (n = 131) and 19 days for nonsupplemented patients (n = 57) with no difference between groups ( P = .2973). Plasma Mn levels were measured at a mean of 28 days, showing no statistical difference ( P = .721). Of the 177 nonsupplemented I patients, 74% demonstrated I deficiencies without supplementation. Time to the development of a Se, Mn, or I deficiency is important to guide supplementation of exclusive PN in children when trace mineral products are short in supply. Our retrospective experience supports assessment of the trace minerals Se at 21 days and Mn at 30 days. It also suggests that some pediatric patients receiving PN are deficient in I.

    Society for Vascular Surgery practice guidelines for the medical treatment of intermittent claudication give a GRADE 1A recommendation for smoking cessation. Active smoking is therefore expected to be low in patients suffering from intermittent claudication selected for vascular surgical intervention. The aim of this study is to evaluate the prevalence of smoking in patients undergoing intervention for intermittent claudication at the national level and to determine the relationship between smoking status and intervention. The Vascular Quality Initiative (VQI) registries for infra-inguinal bypass, supra-inguinal bypass, and peripheral vascular intervention (PVI) were queried to identify patients who underwent invasive treatment for intermittent claudication. Patient factors, procedure type (bypass versus PVI), and level of disease (supra-inguinal versus infra-inguinal) were evaluated for associations with smoking status (active smoking or nonsmoking) by univariate and covariate analysis. Between 2010 and 2015, 101,055 procedures were entered in the 3 registries, with 40,269 (40%) performed for intermittent claudication. Complete data for analysis were present in 37,632 cases. At the time of intervention, 44% of patients were active smokers, with wide variation by regional quality group (16-53%). In covariate analysis, active smoking at treatment was associated with age smoking status. During follow-up, 36% of patients had quit smoking. Predictors of smoking cessation included age ≥70 years (RR 1.45), ABI ≥0.9 (RR 1.12), and bypass procedures (RR 1.22). At the time of treatment, 44% of patients undergoing intervention for intermittent claudication in the VQI were active smokers and there was a wide regional variation. Prevalence of active smoking was greater in the presence of younger age, fewer comorbidities, lower ABI, and supra-inguinal disease. Type of procedure performed, and in turn level of invasiveness required, did not appear to be influenced by smoking

    The vast majority of sudden cardiac arrests occur in patients with structural heart disease and in approximately 10% of the cases, it can occur in those with structurally normal hearts. Brugada syndrome is an autosomal dominant sodium channelopathy that has been implicated in sudden deaths. Given their low prevalence, our knowledge about Brugada syndrome is still evolving. Apart from schizophrenia, there have been no reports of associated medical conditions. We recently encountered a patient with vascular Ehlers-Danlos syndrome who was also found to have Brugada syndrome. Both these conditions share some common clinical presentations including a propensity for sudden death.

    The biological effects of a single high dose of radiation are examined. Both cellular injury and repair are reviewed during early, intermediate, and late phases. Anticipated composite tissue morbidity is detailed for therapeutic radiation doses administered to the head and neck, breast and thorax, and perineum. Patients who demonstrated excessive time-dose fractionation values were irradiated with lower x-ray energies. Those in whom there was an overlap of treatment fields presented a serious challenge to the reconstructive surgeon. Judicious selection of well-vascularized composite tissue outside the portals of irradiation, preferably with a long vascular pedicle, facilitated reconstruction. When possible, both donor and recipient vasculature should be outside the irradiated area to ensure uninterrupted blood flow to the transferred or transplanted tissue

  20. Erythropoietin resistance in end-stage renal disease patient with gastric antral vascular ectasia

    Full Text Available AbstractWe observed a case of recombinant human erythropoietin resistance caused by Gastric Antral Vascular Ectasia in a 40-year-old female with ESRD on hemodialysis. Some associated factors such as autoimmune disease, hemolysis, heart and liver disease were discarded on physical examination and complementary tests. The diagnosis is based on the clinical history and endoscopic appearance of watermelon stomach. The histologic findings are fibromuscular proliferation and capillary ectasia with microvascular thrombosis of the lamina propria. However, these histologic findings are not necessary to confirm the diagnosis. Gastric Antral Vascular Ectasia is a serious condition and should be considered in ESRD patients on hemodialysis with anemia and resistance to recombinant human erythropoietin because GAVE is potentially curable with specific endoscopic treatment method or through surgical procedure.

    Vascular access-related complications are a frequent cause of morbidity in haemodialysis patients and generate high costs. We present the case of an adult patient with end-stage renal disease and recurrent vascular access thrombosis associated with the prothrombin mutation G20210A and renal graft intolerance. The clinical expression of this heterozygous gene mutation may have been favoured by inflammatory state, frequent in dialysis patients. In this patient, the inflammatory response associated with the renal graft intolerance would have favored the development of recurrent vascular access thrombosis in a adult heterozygous for prothrombin mutation G20210A. In the case of early dysfunction of haemodialysis vascular access and after ruling out technical problems, it is convenient to carry out a screening for thrombophilia.

    Freezing of gait (FOG) is one of the most disabling and enigmatic symptoms in Parkinson's disease. Vascular lesions, observed in magnetic resonance imaging (MRI) scans, may produce or exacerbate this symptom. The study includes 22 patients with Parkinson's disease subjects, 12 with freezing of gait and 10 without. All patients underwent an MRI scan and any vascular lesions were analysed using the modified Fazekas scale. Patients with FOG scored higher on the modified Fazekas scale than the rest of the group. Although the two groups contained the same percentage of patients with vascular lesions (50% in both groups), lesion load was higher in the group of patients with FOG. Vascular lesions in the periventricular area and deep white matter seem to be the most involved in the development of FOG. Vascular lesions may contribute to the onset or worsening of FOG in patients with PD. This study suggests that cerebral vascular disease should be considered in patients with FOG.

    2008-01-01

    Mounting evidence from a variety of research fields has drawn attention to the participation of vascular factors in the underlying pathophysiology of Alzheimer's disease (AD). To clarify the influence of vascular and genetic risk factors, we investigated the relationships between cerebral blood flow images provided by single photon emission CT (SPECT) and blood pressure, brain natriuretic peptide (BNP), and ApoE4 phenotyping in AD patients. The present study was based on 197 patients with probable AD. All patients underwent biochemistry tests, neuropsychological evaluation, magnetic resonance imaging (MRI), and 99m Tc ethyl cysteinate dimer (ECD) SPECT. The mini mental state examination (MMSE) score was correlated with the diastolic blood pressure positively, and with BNP negatively. Statistical parametric mapping (SPM) revealed significant hypoperfusion in the posterior cingulate gyri, precuneus, and parieto-temporal region in those patients having ApoE4 as compared to those without ApoE4. When compared to those patients without white matter hyperintensity (WMH) on MRI, those with mild WHM demonstrated significant hypoperfusion in the anterior cingulate gyri, right superior, middle and inferior temporal gyri, and left inferior frontal gyrus, and those with marked WMH demonstrated more expansive hypoperfusion areas on SPM. Those with greater BNP levels showed significant hypoperfusion in the anterior cingulate gyri and superior frontal gyri as compared to those with smaller BNP levels. Posterior hypoperfusion as related to the presence of ApoE4 may imply a degenerative process in AD, whereas anterior hypoperfusion as related to increased BNP levels may indicate the participation of vascular factors in AD.

    This is an observational study of fluorescein angiography (FA) in consecutive patients with rhegmatogenous retinal detachment (RRD) in Changhua Christian Hospital to investigate the peripheral retinal vascular patterns in those patients. All patients had their age, sex, axial length (AXL), and refraction status (RF) recorded. According to the findings in FA of the peripheral retina, the eyes were divided into 4 groups: in group 1, there was a ramified pattern of peripheral retinal vasculature with gradual tapering; in group 2, there was an abrupt ending of peripheral vasculature with peripheral non-perfusion; in group 3, there was a curving route of peripheral vasculature forming vascular arcades or anastomosis; and in group 4, the same as in group 3, but with one or more wedge-shaped avascular notches. Comparisons of age, sex, AXL, and RF, association of breaks with lattice degeneration and retinal non-perfusion, surgical procedures utilized, and mean numbers of operations were made among the four groups. Of the 73 eyes studied, there were 13 eyes (17.8%) in group 1, 3 eyes (4.1%) in group 2, 40 eyes (54.8%) in group 3 and 17 eyes (23.3%) in group 4. Significant differences in age, AXL and RF, and association of retinal breaks to non-perfusion were noted among the four groups. Patients in group 1 had older ages, while younger ages were noted in groups 3 and 4. Eyes in group 1 had the shortest average AXL and were least myopic in contrast to the eyes in groups 3 and 4. Association of retinal breaks and retinal non-perfusion was significantly higher in groups 2, 3 and 4 than in group 1. In conclusion, peripheral vascular anomalies are common in cases with RRD. Patients with peripheral non-perfusion tend to be younger, with longer axial length and have the breaks associated with retinal non-perfusion. PMID:26909812

    Chronic renal failure is a type of clinical syndrome originating from chronic renal diseases. The aim of the study was to investigate the effect of astrogaloside on the inflammation and immunity of renal failure patients receiving maintenance dialysis. We randomly selected 92 renal failure patients receiving maintenance dialysis who were admitted to hospital for treatment between May, 2015 and April, 2016. Patients were randomly divided into the control (n=46) and observation (n=46) groups. Patients in the control group received the regular dialysis plus the basic treatment in Western medicine, while in the observation group, patients additionally received astrogaloside via intravenous injection as treatment. We compared the clinical efficacy of patients between the two groups, residual renal function (RRF), changes in urine volume, variations in inflammatory indicators [C-reaction protein (CRP), interleukin-6 (IL-6), IL-17, and tumor necrosis factor-α (TNF-α)] before and after treatment, and the levels of the thymus-dependent lymphocyte (T cells) subgroup (CD3 + , CD4 + , CD8 + and CD4 + /CD8 + ) in the immune system of patients after treatment. In the observation group, the total effective rate was significantly higher than that in the control group (Prenal failure patients receiving the maintenance dialysis, ameliorate the inflammatory responses, and enhance the immune function, thereby increasing the disease resistance of patients and improving the clinical symptoms.

    Full Text Available INTRODUCTION: Heart failure (HF is a complex syndrome in which effort limitation is associated with deterioration of peripheral musculature. Improving survival rates among these patients have led to the appearance of cases in which other pathologies are associated with HF, such as peripheral vascular insufficiency (PVI. The combination of these two pathologies is common, with significant repercussions for affected patients. OBJECTIVE: To compare functional limitations and quality of life between patients with HF in isolation or HF + PVI. METHOD: Twelve patients with HF+PVI were paired to 12 patients with HF in isolation. All had ejection fraction 0.05. CONCLUSIONS: The study participants who had mixed disease exhibited a greater degree of functional impairment than the group with HF, without reporting worsened quality of life.

    Full Text Available Objectives. To perform a quantitative analysis of the vascular endothelial growth factor (VEGF gene transcription in the skin of ischemic legs and provide information for VEGF in the pathogenesis in critical limb ischemia (CLI. Methods. Skin biopsies were obtained from 40 patients with CLI. Control samples came from 44 patients with chronic venous disease. VEGF gene expression was analysed using quantitative polymerase chain reaction. Results. Patients with CLI had higher skin VEGF expression than control group (RQ: 1.3 ± 0.1 versus 1, P=0.04. Conclusions. We found an association between ischemic skin and an elevated VEGF expression in legs from patients with CLI. These data support that the mechanism for VEGF upregulation in hypoxia conditions is intact and acts appropriately in the ischaemic limbs from patients with CLI.

    Coronary artery calcium (CAC) can be used to estimate vascular age in adults, providing a convenient transformation of CAC from Agatston units into a year's scale. We investigated the role of coronary vascular age in predicting stress-induced myocardial ischemia in subjects with suspected coronary artery disease (CAD). A total of 717 subjects referred to CAC scoring and 82 Rb PET/CT stress-rest myocardial perfusion imaging for suspected CAD were studied. CAC score was measured according to the Agatston method and coronary vascular age by equating estimated CAD risk for chronological age and CAC using the formula 39.1 + 7.25 × ln(CAC + 1). Stress-induced ischemia was present in 105 (15%) patients. Mean chronological age, CAC score, and coronary vascular age were higher (all P age was added to clinical variables. Including vascular age in the model, the global Chi square further increased from 68.77 to 106.38 (P age to clinical data, continuous net reclassification improvement (cNRI) was 0.57, while adding vascular age to clinical data and chronological age cNRI was 0.62. At decision curve analysis, the model including vascular age was associated with the highest net benefit compared to the model including only clinical data, to the model including chronological age and clinical data, and to a strategy considering that all patients had ischemia. The model including vascular age also showed the largest reduction in false-positive rate without missing any ischemic patients. In subjects with suspected CAD, coronary vascular age is strongly associated with stress-induced ischemia. The communication of a given vascular age would have a superior emotive impact improving observance of therapies and healthier lifestyles.

    The aim of the present case report was to investigate the effects of a physiotherapy program combined with sirolimus in a child patient with upper extremity edema and joint limitation due to low-flow vascular malformation. This case report included an 11-year-old male patient (26 kg, 130 cm) diagnosed with congenital lymphovascular malformation on the left and right chest. The patient, who had edema on the upper left extremity and experienced joint limitations, was administered complete decongestive therapy (CDT) and manual therapy in combination with sirolimus. Physiotherapy included a total of 24 sessions, 3 sessions a week for 8 weeks. Following the physiotherapy, the patient was assigned to a home therapy program, and then the maintenance phase of the CDT was initiated. Evaluations were carried out at baseline, at the end of week 8, and after 12 months. Following the physiotherapy program combined with sirolimus, a decrease in extremity volume, an increase in joint movement range, and an improvement in disease-related complaints were observed. Physiotherapy methods combined with sirolimus may be an effective treatment method in patients with vascular malformations. However, further studies with larger sample size are warranted.

    Vascular progenitor cells (VPCs) facilitate angiogenesis and initiate vascular repair by homing in on sites of damage and adhering to extracellular matrix (ECM) proteins. VPCs also contribute to tumor angiogenesis and induce angiogenic switching in sites of metastatic cancer. In this study, the binding of attaching cells in VPC clusters that form in vitro on specific ECM proteins was investigated. VPC cluster assays were performed in vitro on ECM proteins enriched in cancer cells and in remodelling tissue. Profiles of VPC clusters from patients with cancer were compared to healthy controls. The role of VEGF and integrin-specific binding of angiogenic attaching cells was addressed. VPC clusters from cancer patients were markedly increased on fibronectin relative to other ECM proteins tested, in contrast to VPC clusters from control subjects, which formed preferentially on laminin. Specific integrin-mediated binding of attaching cells in VPC clusters was matrix protein-dependent. Furthermore, cancer patients had elevated plasma VEGF levels compared to healthy controls and VEGF facilitated preferential VPC cluster formation on fibronectin. Incubating cells from healthy controls with VEGF induced a switch from the 'healthy' VPC binding profile to the profile observed in cancer patients with a marked increase in VPC cluster formation on fibronectin. The ECM proteins laminin and fibronectin support VPC cluster formation via specific integrins on attaching cells and can facilitate patterns of VPC cluster formation that are distinct in cancer patients. Larger studies, however, are needed to gain insight on how tumor angiogenesis may differ from normal repair processes.

    Although new treatment modalities changed the global approach to hepatocellular carcinoma (HCC), this disease still represents a medical challenge. Currently, the therapeutic stronghold is sorafenib, a tyrosine kinase inhibitor (TKI) directed against the vascular endothelial growth factor (VEGF) family. Previous observations suggested that polymorphisms of VEGF and its receptor (VEGFR) genes may regulate angiogenesis and lymphangiogenesis and thus tumour growth control. The aim of our study was to evaluate the role of VEGF and VEGFR polymorphisms in determining the clinical outcome of HCC patients receiving sorafenib. From a multicentre experience 148 samples (tumour or blood samples) of HCC patients receiving sorafenib were tested for VEGF-A, VEGF-C and VEGFR-1,2,3 single nucleotide polymorphisms (SNPs). Patients' progression-free survival (PFS) and overall survival (OS) were analysed. At univariate analysis VEGF-A alleles C of rs25648, T of rs833061, C of rs699947, C of rs2010963, VEGF-C alleles T of rs4604006, G of rs664393, VEGFR-2 alleles C of rs2071559, C of rs2305948 were significant predictors of PFS and OS. At multivariate analysis rs2010963, rs4604006 and BCLC (Barcelona Clinic Liver Cancer) stage resulted to be independent factors influencing PFS and OS. Once prospectively validated, the analysis of VEGF and VEGFR SNPs may represent a clinical tool to better identify HCC patients more likely to benefit from sorafenib. On the other hand, the availability of more accurate predictive factors could help avoiding unnecessary toxicities to potentially resistant patients who may be optimal candidates for different treatments interfering with other tumour molecular pathways. © 2014 UICC.

    Anticoagulation is a common treatment modality in patients with pulmonary arterial hypertension (PAH). Further studies are needed to appropriately assess the risk/benefit ratio of anticoagulation, particularly in PAH patients receiving PAH-specific therapies. We use observational long-term data on PAH patients treated with subcutaneous (SQ) treprostinil from a large open-label study. Patients were followed for up to 4 years. The use of warfarin and bleeding events were recorded. At total of 860 patients (age [mean±SD] 46±15 years, 76% female, 83% Caucasian, 49% idiopathic PAH, and 76% New York Heart Association [NYHA] functional class III) were included. All patients received SQ treprostinil (15% also other pulmonary hypertension [PH]-therapies) and 590 (69%) received warfarin during the study. The proportions of women, African American, and idiopathic pulmonary hypertension (IPAH) patients were higher in the group receiving warfarin. A higher proportion of patients with congenital heart disease and portopulmonary hypertension did not receive warfarin. There were no differences in unadjusted long-term survival between PAH patients receiving warfarin or not (log-rank test, P value=.69), even when only considering idiopathic PAH (P=.32). In addition, no difference was found in adjusted long-term survival both in PAH (P=.84) and idiopathic PAH patients (P=.44) based on the use of warfarin. Furthermore, no survival difference based on the use of warfarin were noted between propensity score-matched PAH patients (P=.37). Long-term anticoagulation with warfarin was not associated with any significant effect on survival in PAH or idiopathic PAH patients treated with SQ treprostinil. © 2017 John Wiley & Sons Ltd.

    Previous studies of patients with end-stage renal disease have examined the role of fluid shifts on apnea-hypopnea episodes, but the association between volume overload and patient-reported sleep quality or duration has not been well-established. We studied the association between predialysis bioimpedance spectroscopy-derived volume estimates and self-reported sleep quality and duration in 638 patients in the United States Renal Data System ACTIVE/ADIPOSE study receiving hemodialysis from 2009 to 2011. We used questionnaires to assess self-reported sleep duration and quality. We used relative hydration status (fluid overload/extracellular water; FO/ECW) as the primary predictor and examined associations with hours of sleep duration using linear regression. We used multivariable ordinal logistic regression to determine the association between categories of relative hydration status (normal hydration [FO/ECW  15%]) and four levels of difficulty with falling asleep, waking, and returning to sleep. Higher relative hydration status was associated with fewer hours of sleep (-0.31 hours per 10%, 95% confidence interval (CI) -0.49 to -0.13). Compared to the normal hydration group, there was a statistically significant association between higher relative hydration status category and more frequent nighttime waking (OR: mild overhydration 1.92 [95% CI 1.23-2.99], hyperhydration 1.87 [95% CI 1.16-2.99]), a trend toward more difficulty returning to sleep (OR: mild overhydration 1.46 [95% CI 0.94-2.27], hyperhydration 1.52 [95% CI 0.95-2.43]), and no association between relative hydration category and difficulty falling asleep. Hydration status was associated with self-reported sleep duration in patients on dialysis. Future studies should prospectively examine the effects of optimizing fluid status on sleep duration and quality. © 2016 International Society for Hemodialysis.

    Objective: To investigate the serum expression of leptin and vascular endothelial growth factor (VEGF) in patients with breast cancer and assess its diagnostic significance. Methods: Thirty-six patients with breast cancer and thirty-one patients with benign breast disorders entered this study. Serum concentration of leptin (with RIA) and VEGF ( with ELISA) were determined in these patients before operation as well as in 56 controls. All the tested subjects were post-menopausal women. Results: The difference between the leptin levels in the controls and patients with benign breast disorders was significantly; 80 was the difference between the leptin levels in controls and patients with breast cancer. Significant difference also existed between the VEGF levels in controls and patients with cancer as well as between the levels in patients with benign breast disease and patients with cancer. Also, the serum leptin and VEGF levels in the cancerous patients with axillary metastasis were significantly higher than those in patients without metastasis. Conclusion: Serum leptin and VEGF might be taken as diagnostic tumor markers for malignanay and metastasis in patients with breast cancer. (authors)

    Full Text Available Studies of endothelial dysfunction in patients with respiratory diseases have become relevant in recent years. Perhaps endothelial dysfunction and high arterial stiffness bind bronchopulmonary and cardiovascular diseases.Aim. To reveal features of disturbances of arterial wall vasoregulatory function in patients with chronic obstructive pulmonary disease (COPD in the presence and absence of arterial hypertension (HT.Material and methods. The study included 50 patients with COPD with normal blood pressure (BP and 85 patients with COPD and HT. Control group was presented by 20 practically healthy men comparable in age with COPD patients. Tests with reactive hyperemia (endothelium-dependent dilation and nitroglycerin (endothelium-independent dilation were performed in order to evaluate endothelium function. The number of desquamated endotheliocytes in the blood was determined.Results. In patients with COPD and HT in comparison with COPD patients without HT and healthy individuals more pronounced damages of the vascular wall, endothelium vasoregulatory function disturbances and a tendency to the reduction in endothelium-dependent vasodilation were determined both during COPD exacerbation and remission. These differences were most pronounced during the COPD exacerbation. In patients with COPD and HT in comparison with COPD patients without HT the damage of the vascular wall was more pronounced during the remission and endothelium-dependent dilatation disorder – during the exacerbation. The revealed disorders in patients with COPD and HT were associated with smoking status (r=0.61, p<0.01, severity of bronchial obstruction (r=-0.49, p<0.05, and hypoxemia (r=-0.76, p<0.01. We noted relationships between the parameters of 24-hour BP monitoring and remodeling of the brachial artery (r=0.34, p<0.05, endothelium lesion (r=0.25, p<0.05, and impairment of its vasoregulating function (r=-0.58, p<0.05. At that, the following parameters were important: the

    To assess the opinions of vascular surgery trainees on the new Accreditation Council for Graduate Medical Education (ACGME) guidelines. A questionnaire was developed and electronically distributed to trainee members of the Society for Vascular Surgery. Of 238 eligible vascular trainees, 38 (16%) participated. Respondents were predominantly 30 to 35 years of age (47%), male (69%), in 2-year fellowship (73%), and at large academic centers (61%). Trainees report occasionally working while fatigued (63%). Fellows were more likely to report for duty while fatigued (P = .012) than integrated vascular residents. Respondents thought further work-hour restrictions would not improve patient care or training (P life. Respondents reported that duty hours should vary by specialty (81%) and allow flexibility in the last years of training (P balanced against the need to adequately train vascular surgeons.

    Tissue-engineered blood vessels (TEBVs) are promising in regenerating a live vascular replacement. However, the vascular cell source is limited, and it is crucial to develop a scaffold that accommodates new type of vascular progenitor cells and facilitates in vivo lineage specification of the cells into functional vascular smooth muscle cells (VSMCs) to regenerate vascular tissue. In the present study, integration-free human induced pluripotent stem cells (hiPSCs) were established from patient peripheral blood mononuclear cells through episomal vector nucleofection of reprogramming factors. The established hiPSCs were then induced into mesoderm-originated cardiovascular progenitor cells (CVPCs) with a highly efficient directed lineage specification method. The derived CVPCs were demonstrated to be able to differentiate into functional VSMCs. Subcutaneous implantation of CVPCs seeded on macroporous nanofibrous poly(l-lactide) scaffolds led to in vivo VSMC lineage specification and matrix deposition inside the scaffolds. In summary, we established integration-free patient-specific hiPSCs from peripheral blood mononuclear cells, derived CVPCs through directed lineage specification, and developed an advanced scaffold for these progenitor cells to further differentiate in vivo into VSMCs and regenerate vascular tissue in a subcutaneous implantation model. This study has established an efficient patient-specific approach towards in vivo regeneration of vascular tissue. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The hemodynamic changes in hepatic vascular structures of hepatosteatosis patients were examined using Doppler ultrasonography. Ninety hepatosteatosis patients, classified as mild, moderate or severe, and 30 healthy volunteers were included in this 120-person study. The height, weight, liver size, blood lipids and blood liver function tests of the subjects were measured. Those values were compared in the patient and control groups. In the patient and control groups, color duplex Doppler ultrasonography was used to examine portal vein peak velocity, portal vein flow volume, hepatic artery resistive index (RI), hepatic artery pulsatility index (PI) and hepatic artery flow volume. Similarly to the degree of hepatosteatosis, increases in body mass index, liver size, liver enzyme levels and blood lipid levels were statistically significant (p<0.05). While the difference in portal vein peak velocity in the hepatosteatosis and control groups was not statistically significant, there was an increasing reduction in the degree of steatosis (p>0.05). As the degree of hepatosteatosis increased, there was a reduction in hepatic artery flow volume, portal vein flow volume and total flow volume that was not statistically significant. In the mild hepatosteatosis group, hepatic artery RI and PI values were statistically significantly lower than in the other groups (p<0.05). In the severe hepatosteatosis group, although the hepatic artery RI and PI values were not statistically significant, there was a minimal increase compared to the other groups. It is believed that those results were caused by a reduction in liver compliance and hepatic vascular compliance, in addition to resistance increase in vascular structures

    OBJECTIVE Concurrent surgeries, also known as "running two rooms" or simultaneous/overlapping operations, have recently come under intense scrutiny. The goal of this study was to evaluate the operative time and outcomes of concurrent versus nonconcurrent vascular neurosurgical procedures. METHODS The authors retrospectively reviewed 1219 procedures performed by 1 vascular neurosurgeon from 2012 to 2015 at the University of California, San Francisco. Data were collected on patient age, sex, severity of illness, risk of mortality, American Society of Anesthesiologists (ASA) status, procedure type, admission type, insurance, transfer source, procedure time, presence of resident or fellow in operating room (OR), number of co-surgeons, estimated blood loss (EBL), concurrent vs nonconcurrent case, severe sepsis, acute respiratory failure, postoperative stroke causing neurological deficit, unplanned return to OR, 30-day mortality, and 30-day unplanned readmission. For aneurysm clipping cases, data were also obtained on intraoperative aneurysm rupture and postoperative residual aneurysm. Chi-square and t-tests were performed to compare concurrent versus nonconcurrent cases, and then mixed-effects models were created to adjust for different procedure types, patient demographics, and clinical indicators between the 2 groups. RESULTS There was a significant difference in procedure type for concurrent (n = 828) versus nonconcurrent (n = 391) cases. Concurrent cases were more likely to be routine/elective admissions (53% vs 35%, p returns to the OR (3.3% vs 6.9%; all p return to the OR and 30-day mortality were significantly lower in concurrent cases (odds ratio 0.55, 95% confidence interval 0.31-0.98, p = 0.0431, and odds ratio 0.81, p fashion. After adjusting for patient demographics, procedure type, and clinical indicators, concurrent cases had longer procedure times, but equivalent patient outcomes, as compared with nonconcurrent vascular neurosurgical procedures.

    Additive manufacturing (3D printing) technology offers a great opportunity towards development of patient-specific vascular anatomic models, for medical device testing and physiological condition evaluation. However, the development process is not yet well established and there are various limitations depending on the printing materials, the technology and the printer resolution. Patient-specific neuro-vascular anatomy was acquired from computed tomography angiography and rotational digital subtraction angiography (DSA). The volumes were imported into a Vitrea 3D workstation (Vital Images Inc.) and the vascular lumen of various vessels and pathologies were segmented using a "marching cubes" algorithm. The results were exported as Stereo Lithographic (STL) files and were further processed by smoothing, trimming, and wall extrusion (to add a custom wall to the model). The models were printed using a Polyjet printer, Eden 260V (Objet-Stratasys). To verify the phantom geometry accuracy, the phantom was reimaged using rotational DSA, and the new data was compared with the initial patient data. The most challenging part of the phantom manufacturing was removal of support material. This aspect could be a serious hurdle in building very tortuous phantoms or small vessels. The accuracy of the printed models was very good: distance analysis showed average differences of 120 μm between the patient and the phantom reconstructed volume dimensions. Most errors were due to residual support material left in the lumen of the phantom. Despite the post-printing challenges experienced during the support cleaning, this technology could be a tremendous benefit to medical research such as in device development and testing.

    Full Text Available Retinal vascular occlusion is the most common cause of retinopathy leading to severe visual loss in all age groups. Central retinal vein occlusion (CRVO is usually seen in older age group and is often associated with systemic vascular diseases. Although the exact cause and effect relationship has not been proven, central retinal vein occlusion has been associated with various systemic pathological conditions, hence a direct review of systems toward the various systemic and local factors predisposing the central retinal vein occlusion is advocated. We describe the development of central retinal venous occlusion with associated cystoid macular edema (CME in two healthy infertile women who were recruited for in vitro fertilization cycle for infertility. Predisposing risk factors associated with central retinal vein occlusion are obesity, sedentary life style, smoking, and some systemic diseases such as hyperlipidemia, hypertension, associated autoimmune disorders e.g., antiphospholipid antibody syndrome, lupus, diabetes mellitus, cardiovascular disorders, bleeding or clotting disorders, vasculitis, closed-head trauma, alcohol consumption, primary open-angle glaucoma or angle-closure glaucoma.In our patients, they were ruled out afterdoing allpertaining investigations. The cases were managed with further avoidance of oral contraceptives and intra-vitreal injections of Bevacizumab (Avastin, an anti-vascular endothelial growth factor (anti-VEGF drug and Triamcinolone acetonide (a long acting synthetic steroid. Hence, even if no systemic diseases are detected. Physical examinations are recommended periodically for young women on oral contraceptive pills.

  5. Patients with atherosclerotic vascular disease: how low should plasma homocyst(e)ine levels go?

    Science.gov (United States)

    Spence, J D

    2001-01-01

    Plasma homocyst(e)ine level is a strong independent risk factor for vascular disease. The spelling of homocyst(e)ine reflects that what is measured, and what constitutes the risk factor; it includes homocysteine, homocystine (the dimer of homocysteine) and mixed cysteine-homocysteine disulfide. Homocyst(e)ine levels above 10.2 micro mol/L are associated with a doubling of coronary risk, and levels above 20 micro mol/L are associated with a 9.9-fold increase in risk compared with levels below 9 micro mol/L. The mechanisms by which homocyst(e)ine promotes vascular disease include increased thrombosis, consumption of nitric oxide, endothelial injury, and reduced thrombolysis. Homocyst(e)ine is an independent predictor of carotid atherosclerosis. Vitamin therapy with folate, pyridoxine (vitamin B(6)), and cyanocobalamin (vitamin B(12)) reduces blood levels of homocyst(e)ine, improves endothelial function, reduces levels of fibrinogen and lipoprotein(a), improves thrombolysis, and in uncontrolled clinical observation, leads to regression of carotid plaque. These lines of evidence support a causal relationship between homocyst(e)ine and atherosclerosis, and suggest that in patients with vascular disease, an appropriate target level for therapy may be below 9 or 10 micro mol/L. Randomized controlled studies are under way to determine whether vitamin therapy is effective in secondary prevention of myocardial infarction and stroke.

    One of the frequent questions in obstetric practice is to determine placental vascular changes that may account for abnormal Doppler flow velocity alterations in maternal uterine vessels from women and fetuses without pregnancy pathology. A retrospective morphometric study was realized using 27 placentas from patients submitted for Doppler flow velocity exam during pregnancy. The placentas were morphologically examined using hematoxylin-eosin staining. Measurements of villi were made with the use of a video camera coupled to a common light microscope and a computer with automatic image analyzing software. Of the 27 placentas, 13 (48%) were of patients showing unaltered Doppler and 14 (52%) showing altered Doppler. The number of stem villi vessels was significantly larger in the placentas of patients with Doppler exam alterations (P = 0.003). This group also presented greater stem villi vessel thickness, although without significant difference. The number of intermediary and terminal villi vessels was greater in the placentas of patients with altered Doppler exams (P < 0.001), and a greater terminal villi area was observed in these cases (P < 0.001). The morphological proof that uterine artery Doppler flow velocity exam alterations are associated with placental vascular alterations demonstrates the importance of this exam during prenatal care, even in the absence of maternal-fetal alterations.

    Although calcimimetics cinacalcet can reduce parathyroid hormone level and control secondary hyperparathyroidism in end-stage renal disease patients, risk of vascular calcification remains high. Whether cinacalcet can further reduce vascular damage or arterial stiffness is unknown. We studied the effect of cinacalcet in 33 peritoneal dialysis patients with inadequately controlled secondary hyperparathyroidism despite standard treatment. The primary outcome was the aortic pulse wave velocity at 26 and 52 months after cinacalcet treatment. The pulse wave velocity was compared with that of a matched control cohort of 37 peritoneal dialysis patients with secondary hyperparathyroidism. Thirty-three patients completed the cinacalcet treatment, after median dialysis duration of 1.0 year. Significant improvement of parathyroid hormone level was achieved after 52 weeks, from 87.5 ± 28.7 pmol/L to 34.5 ± 45.5 pmol/L (P hyperparathyroidism, a reduction of 60.6% parathyroid hormone level after cinacalcet treatment for one year did not reduce the carotid-femoral pulse wave velocity. © 2014 Asian Pacific Society of Nephrology.

    This study was designed to assess endovascular intervention for central venous cannulation in patients with vascular occlusion after previous catheterization. Patients referred for endovascular management of central venous occlusion during a 42-month period were identified from a regional endovascular database, providing prospective information on techniques and clinical outcome. Corresponding patient records, angiograms, and radiographic reports were analyzed retrospectively. Sixteen patients aged 48 years (range 0.5-76), including 11 females, were included. All patients but 1 had had multiple central venous catheters with a median total indwelling time of 37 months. Eleven patients cannulated for hemodialysis had had significantly fewer individual catheters inserted compared with 5 patients cannulated for nutritional support (mean 3.6 vs. 10.2, pvenous occlusions. Patients were subjected to recanalization (n=2), recanalization and percutaneous transluminal angioplasty (n=5), or stenting for vena cava superior syndrome (n=1) prior to catheter insertion. The remaining 8 patients were cannulated by avoiding the occluded route. Central venous occlusion occurs particularly in patients under hemodialysis and with a history of multiple central venous catheterizations with large-diameter catheters and/or long total indwelling time periods. Patients with central venous occlusion verified by CT or MRT venography and need for central venous access should be referred for endovascular intervention.

    PURPOSE: To examine associations between retinal vascular geometry (tortuosity, branching coefficient [BC] and length-diameter ratio [LDR]) and diabetic proliferative retinopathy (PDR), nephropathy, and peripheral neuropathy in patients with type 1 diabetes mellitus (T1DM). METHODS: A cohort...... of patients with T1DM participated in a clinical examination in 2011. Blood and urine analyses were done and retinal images taken. PDR was defined as Early Treatment Diabetic Retinopathy Study level 61 or above, nephropathy as albumin-creatinin ratio ≥300 mg/g, and neuropathy as vibration perception threshold.......8% were male. Prevalence of PDR, nephropathy, and neuropathy were 26.5%, 6.8%, and 10.1% , respectively. Patients with increased arteriolar BC had a higher risk of nephropathy (OR: 3.10, 95% CI: [1.01-9.54]). Patients with increased venular BC had a higher risk of neuropathy (OR: 2.11, 95% CI: [1...

    Vascular and cardiac safety during tyrosine kinase inhibitor (TKI) therapy is an emerging issue. We evaluated vascular/cardiac toxicities associated with long-term bosutinib treatment for Philadelphia chromosome-positive (Ph+) leukemia based on treatment-emergent adverse events (TEAEs) and changes in QTc intervals and ejection fraction in two studies: a phase 1/2 study of second-/third-/fourth-line bosutinib for Ph+ leukemia resistant/intolerant to prior TKIs (N = 570) and a phase 3 study of first-line bosutinib (n = 248) versus imatinib (n = 251) in chronic phase chronic myeloid leukemia. Follow-up time was ≥48 months (both studies). Incidences of vascular/cardiac TEAEs in bosutinib-treated patients were 7%/10% overall with similar incidences observed with first-line bosutinib (5%/8%) and imatinib (4%/6%). Few patients had grade ≥3 vascular/cardiac events (4%/4%) and no individual TEAE occurred in >2% of bosutinib patients. Exposure-adjusted vascular/cardiac TEAE rates (patients with events/patient-year) were low for second-line or later bosutinib (0.037/0.050) and not significantly different between first-line bosutinib (0.015/0.024) and imatinib (0.011/0.017; P ≥ 0.267). Vascular/cardiac events were managed mainly with concomitant medications (39%/44%), bosutinib treatment interruptions (18%/21%), or dose reductions (4%/8%); discontinuations due to these events were rare (0.7%/1.0%). Based on logistic regression modelling, performance status >0 and history of vascular or cardiac disorders were prognostic of vascular/cardiac events in relapsed/refractory patients; hyperlipidemia/hypercholesterolemia and older age were prognostic of cardiac events. In newly diagnosed patients, older age was prognostic of vascular/cardiac events; history of diabetes was prognostic of vascular events. Incidences of vascular and cardiac events were low with bosutinib in the first-line and relapsed/refractory settings following long-term treatment in patients

    Objective: To investigate CT features on increased cerebral vascular density and its pathological mechanism in patients with cyanotic congenital heart disease (CCHD). Methods: Preoperative brain CT scan and clinical data in 82 patients suffering from CCHD were analyzed. According to the increased levels of vascular density, patients were divided into 4 groups: normal, mild, moderate and severe. Relationships between the increased levels of vascular density and Hb, RBC, HCT, as well as the degree of cyanosis,were studied. AVONA was carried out to test blood CT value of cerebral sinuses, Hb, RBC and HCT in different groups. Descriptive analysis and linear regression were adopted to study the correlation between blood CT value and Hb concentration. The relationship of increased vascular density to degrees of cyanosis was analysed by Spearman. Results: Among 82 patients, 12 patients (14.6%) were found in the group of normal vascular density and 70 patients (85.4%) in the increased vascular density group. Among 70 patients with increased vascular density, 22 patients (26.8% ) with (55.4 ± 2.6) HU, (169 ±6)g/L of Hb, (5.8 ±0.3) × 10 12 /L of RBC and 0.51 ±0.03 of HCT, 29 patients (35.4%) with (61.3 ± 2.9) HU, (209 ± 15 ) g/L, (7.1 ± 0.4) × 10 12 /L, 0.66 ± 0.06 and 19 patients (23.2%) with (68.8 ± 4.2) HU, (242 ± 23) g/L, (8.3 ± 0.9) × 10 12 /L, 0.78 ± 0.08 were observed in the mild,moderate and severe group,respectively. There were significant differences in distribution of blood CT value (HU), Hb, RBC and HCT in different groups (F=163.263, 134.703, 120.974, 136.541; P<0.01). Blood CT value was positively correlated with Hb concentration (r=0.98, P<0.01). Vascular density was also positively correlated with the degree of cyanosis (r=0.86, P<0.01). Conclusions: Cerebral vascular density of patients suffering from CCHD presented different levels of increases based on CT scan results due to rise of RBC stimulated by anoxia. The increased level of vascular

    Full Text Available Objective: To study the relationship of serum sphingosine 1-phosphate (S1P and heparin cofactor II (HCII levels with vasoactive substances and cytokines in patients with cerebral vascular restenosis after stent implantation. Methods: 52 patients who received cerebrovascular stent implantation and developed restenosis in our hospital between May 2012 and December 2015 were collected as observation group, and 40 healthy patients with cerebrovascular stent implantation who had re-examination in our hospital during the same period were selected as control group. ELISA method was used to detect serum S1P and HC-II levels as well as vasoactive substance and inflammatory factor contents. Spearman correlation analysis was used to evaluate the relationship of serum S1P and HC-II levels with vasoactive substances and inflammatory factors. Results: Serum S1P and HC-II levels of observation group were lower than those of control group (P<0.05; serum vasoactive substances endothelin (ET, angiotensin II (AngII and thromboxane B2 (TXB2 contents of observation group were higher than those of control group while nitric oxide (NO content was lower than that of control group (P<0.05; serum inflammatory factors hypersensitive C-reactive protein (hs-CRP, interleukin-1 (IL-1, IL-6, IL-8 and IL-11 contents of observation group were higher than those of control group (P<0.05. Serum S1P and HC-II levels in patients with cerebral vascular restenosis after stent implantation were directly correlated with vasoactive substance and inflammatory factor contents. Conclusion: Serum S1P and HC-II levels decrease in patients with cerebral vascular restenosis after stent implantation, and it is an important cause of cerebral vascular dysfunction and systemic inflammatory response.

    Neural stem cells are characterized by the ability to differentiate and stably express exogenous ge-nes. Vascular endothelial growth factor plays a role in protecting local blood vessels and neurons of newborn rats with hypoxic-ischemic encephalopathy. Transplantation of vascular endothelial growth factor-transfected neural stem cells may be neuroprotective in rats with cerebral palsy. In this study, 7-day-old Sprague-Dawley rats were divided into ifve groups: (1) sham operation (control), (2) cerebral palsy model alone or with (3) phosphate-buffered saline, (4) vascular en-dothelial growth factor 165 + neural stem cells, or (5) neural stem cells alone. hTe cerebral palsy model was established by ligating the letf common carotid artery followed by exposure to hypox-ia. Phosphate-buffered saline, vascular endothelial growth factor + neural stem cells, and neural stem cells alone were administered into the sensorimotor cortex using the stereotaxic instrument and microsyringe. Atfer transplantation, the radial-arm water maze test and holding test were performed. Immunohistochemistry for vascular endothelial growth factor and histology using hematoxylin-eosin were performed on cerebral cortex. Results revealed that the number of vas-cular endothelial growth factor-positive cells in cerebral palsy rats transplanted with vascular endothelial growth factor-transfected neural stem cells was increased, the time for ifnding water and the ifnding repetitions were reduced, the holding time was prolonged, and the degree of cell degeneration or necrosis was reduced. hTese ifndings indicate that the transplantation of vascu-lar endothelial growth factor-transfected neural stem cells alleviates brain damage and cognitive deifcits, and is neuroprotective in neonatal rats with hypoxia ischemic-mediated cerebral palsy.

    Depression among patients with vascular dementia is frequently overlooked and potentially causes significant morbidity. There is limited data in Malaysia on the subject and this study was conducted to determine the prevalence of depression in vascular dementia (VaD) in UKMMC. This was a cross-sectional study involving diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM IV) criteria and who had a mini mental state examination (MMSE) score of less than 26. All patients were interviewed, examined clinically and their previous brain computer tomography (CT) were reviewed. The prevalence of depression was determined using the Cornell scale of depression. A total of 76 patients were recruited with a mean age of 70.5 ± 9.5 years. The median duration of illness was 2.0 (1.0-4.8) years. The prevalence of depression in the study population was 31.6%. The patients with depression had a significant older mean age (74.5±8.7 years old) compared to those without depression (68.6±9.4 years old). Patients with large artery stroke of less than 3 years had significant higher frequency of depression (53.6%) compared to patients with small artery stroke (23.8%) and patients with right sided large artery stroke had significantly higher frequency of depression compared to left (70% vs. 44.4%). Median MMSE score (17.0) for depressed patients was significantly lower compared with median MMSE score (22.5) for non depressed patients. Median Barthel Index (30.0) for depressed patients was significantly lower compared with median Barthel score for non depressed patients. Depression was prevalent among post stroke patients with VaD in UKMMC particularly for patients with older age, large artery stroke, right sided large artery stroke, low MMSE score and low Barthel Index. Early recognition of high risk patients is important in the holistic management of patients to prevent significant morbidity arising from depression.

The abstracts for all studies meeting initial search criteria were reviewed; relevant studies were included. No prospective studies were found; however, four retrospective case studies were identified that examined LASIK surgery in patients with CVD. Several case reports were also identified in similar fashion.Results: The FDA considers CVD a relative contraindication to LASIK surgery, due largely to the ocular complications associated with disease in the CVD spectrum. However, recent studies of LASIK in patients with CVD indicate LASIK may be safe for patients with very well-controlled systemic disease, minimal ocular manifestations, and no clinical signs or history of dry

    Full Text Available Vascular calcification is common and may affect cardiac function in patients with end-stage renal disease (ESRD. However, little is known about the effect of residual renal function on vascular calcification and cardiac function in patients on hemodialysis.This study was conducted between January 2014 and January 2017. One hundred six patients with residual renal function on maintenance hemodialysis for 3 months were recruited. We used residual renal urea clearance (KRU to measure residual renal function. First, abdominal aortic calcification score (AACS and brachial-ankle pulse wave velocity (baPWV were measured in patients on hemodialysis. Second, we performed echocardiography and investigated new cardiovascular events after study enrollment.The median KRU was 0.9 (0.3-2.5 mL/min/1.73m2. AACS (4.0 [1.0-10.0] vs. 3.0 [0.0-8.0], p = 0.05 and baPWV (1836.1 ± 250.4 vs. 1676.8 ± 311.0 cm/s, p = 0.01 were significantly higher in patients with a KRU < 0.9 mL/min/1.73m2 than a KRU ≥ 0.9 mL/min/1.73m2. Log-KRU significantly negatively correlated with log-AACS (ß = -0.29, p = 0.002 and baPWV (ß = -0.19, P = 0.05 after factor adjustment. The proportion of left ventricular diastolic dysfunction was significantly higher in patients with a KRU < 0.9 mL/min/1.73m2 than with a KRU ≥ 0.9 mL/min/1.73m2 (67.9% vs. 49.1%, p = 0.05. Patients with a KRU < 0.9 mL/min/1.73m2 showed a higher tendency of cumulative cardiovascular events compared to those with a KRU ≥ 0.9 ml/min/1.73m2 (P = 0.08.Residual renal function was significantly associated with vascular calcification and left ventricular diastolic dysfunction in patients on hemodialysis.

    To clarify the characteristics of cerebrovascular lesions in subtypes of vascular ocular syndrome, including amaurosis fugax (AF), retinal artery occlusion (RAO), and retinal vein occlusion (RVO), 93 patients with vascular ocular syndrome were studied by means of carotid ultrasonography (US) and brain computerized tomography (CT). The subjects comprised 21 patients with AF, 37 with RAO, and 35 with RVO who were sequentially given these diagnoses by the department of ophthalmology. On the basis of US findings, carotid lesions were defined as the presence of plaque or stenotic changes. CT findings were assessed for the presence and distribution of low-density areas (LDAs). Mean age was similar in each group, ranging from 64.5 to 67.4 years. The RAO group had high rates of men, hypertension, and smokers. US showed that the prevalence of carotid lesions ipsilateral to the affected eye was high in the RAO group and that severe stenosis and ulcerated plaque were present in 28.6% of the AF group and 45.9% of the RAO group. On CT examination, cerebral infarctions appeared as LDAs in about 10% of the patients in each group, and the incidence and distribution of LDAs were similar. Of 13 patients with cerebral infarction, only 2 were presumably due to carotid lesions; the others had a variety of causes. The discrepancy between US and CT findings was attributed to the small number of patients with cerebral infarction, since most patients had visual defects as an initial symptom. Our results suggest that extracranial carotid lesions, considered to be a major risk factor for stroke, should be carefully assessed in patients with AF or RAO to prevent further stroke. (author)

    To compare the efficacy of intravenous iron and oral iron for prevention of blood transfusions in gynecologic cancer patients receiving platinum-based chemotherapy. Sixty-four non anemic gynecologic cancer patients receiving adjuvant platinum-based chemotherapy were stratified and randomized according to baseline hemoglobin levels and chemotherapy regimen. The study group received 200mg of intravenous iron sucrose immediately after each chemotherapy infusion. The control group received oral ferrous fumarate at a dose of 200mg three times a day. Complete blood count was monitored before each chemotherapy infusion. Blood transfusions were given if hemoglobin level was below 10mg/dl. There were 32 patients in each group. No significant differences in baseline hemoglobin levels and baseline characteristics were demonstrated between both groups. Nine patients (28.1%) in the study group and 18 patients (56.3%) in the control group required blood transfusion through 6 cycles of chemotherapy (p=0.02). Fewer median number of total packed red cell units were required in the study group compared to the control group (0 and 0.5 unit, respectively, p=0.04). Serious adverse events and hypersensitivity reactions were not reported. However, constipation was significantly higher in the control group (3.1% and 40.6%, p=gynecologic cancer patients receiving platinum-based chemotherapy, associated with less constipation than the oral formulation. © 2013 Elsevier Inc.

    Conclusion: Hyponatraemia, hyperkalaemia, and hypochloremia characterized some of the electrolyte imbalance among TB patients receiving treatments. The raised level of bicarbonate may be attributed to overcorrection of respiratory acidosis often found in patients with tuberculosis. Monitoring electrolytes is therefore an important component of TB management.

    Full Text Available Background: Electroconvulsive therapy (ECT is the one of the oldest and effective treatments in psychiatry today. It has been used in a wide variety of psychiatric disorders in both young and old patients. Aims of the study: The present study is a retrospective chart review of geriatric patients receiving ECT as a treatment option in a tertiary care general hospital psychiatry setting. Methodology: The study evaluated ECT records over a 5-year period between the years 2010 and 2014, and it was observed that 23 elderly patients (aged ≥60 years had received ECT. Results: The patients received modified bitemporal ECT using a brief pulse ECT machine and had no major complications. A total of 184 ECT treatments were administered at an average of 8 treatments per case. The major diagnoses of patients were schizophrenia and major depression. The main indications of ECT were intolerance to medication, suicidal behavior and aggression. Out of the 23 elderly patients, 18 (78.26% showed a good response to ECT. The only complication noted was memory loss and confusion in 3 cases. Patients with medical illnesses like hypertension, diabetes and both together received ECT without any complications. Conclusions: This study adds to the scarce database on the use of ECT in elderly patients in India and adds evidence to the fact that ECT is a safe and effective treatment in the elderly.

    The aim of this fMRI study was to evaluate the motor reorganization (cerebral plasticity) and the risk of motor deficit in patients presenting with tumors and vascular malformations, within the framework of their pre-surgical planning. Functional MR imaging data was obtained from 17 patients. Ten patients (seven with tumors and three with vascular malformations) presented with motor reorganization. The results of the present study suggest that the evaluation of the cerebral reorganization is an essential step in predicting the risk of motor deficit in patients having surgical indication for treatment. Furthermore, the cerebral reorganization constitutes an important factor for surgical decision

    Vascular endothelial growth factor (VEGF) is expressed in human bladder tumors. A phase II study was conducted to assess the VEGF inhibitor pazopanib in patients with metastatic, urothelial carcinoma. Nineteen patients with one prior systemic therapy were enrolled. No objective responses were observed and median progression-free survival was 1.9 months. The role of anti-VEGF therapies in urothelial carcinoma remains to be determined. Background Vascular endothelial growth factor (VEGF) is produced by bladder cancer cell lines in vitro and expressed in human bladder tumor tissues. Pazopanib is a vascular endothelial receptor tyrosine kinase inhibitor with anti-angiogenesis and anti-tumor activity in several preclinical models. A 2-stage phase II study was conducted to assess the activity and toxicity profile of pazopanib in patients with metastatic, urothelial carcinoma. Methods Patients with one prior systemic therapy for metastatic urothelial carcinoma were eligible. Patients received pazopanib at a dose of 800 mg orally for a 4-week cycle. Results Nineteen patients were enrolled. No grade 4 or 5 events were experienced. Nine patients experienced 11 grade 3 adverse events. Most common toxicities were anemia, thrombocytopenia, leucopenia, and fatigue. For stage I, none of the first 16 evaluable patients were deemed a success (complete response or partial response) by the Response Evaluation Criteria In Solid Tumors criteria during the first four 4-week cycles of treatment. Median progression-free survival was 1.9 months. This met the futility stopping rule of interim analysis, and therefore the trial was recommended to be permanently closed. Conclusions Pazopanib did not show significant activity in patients with urothelial carcinoma. The role of anti-VEGF therapies in urothelial carcinoma may need further evaluation in rational combination strategies. PMID:23891158

    We have used near-infrared spectroscopy to measure the hemoglobin saturation at rest and during exercise on patients affected by peripheral vascular disease (PVD). The instrument used in our study is a frequency-domain tissue oximeter which employs intensity modulated (110 MHz) laser diodes. We examined 9 subjects, 3 of which were controls and 6 were patients affected by stage II PVD. The optical probe was located on the calf muscle of the subjects. The measurement protocol consisted of: (1) baseline (approximately 5 min); (2) stationary bicycle exercise (approximately 5 min); (3) recovery (approximately 15 min). The change in hemoglobin saturation during exercise ((Delta) Y) and the recovery time after exercise (trec) were significantly greater in the PVD patients ((Delta) Y equals -21 +/- 3%, trec equals 5.9 +/- 3.8 min) than in the control subjects ((Delta) Y equals 2 +/- 3%, trec equals 0.6 +/- 0.1 min).

    Full Text Available Introduction: The creation and maintenance of a good vascular access is mandatory for a successful haemodialysis sessions and the survival of a Chronic Kidney Disease patient. Aim: The aim of the present cross-sectional study was to look into the vascular access complications in haemodialysed patients with or without Diabetes Mellitus (DM and to find any possible correlation of these complications with Diabetes Mellitus. Methods: For this cross-sectional study data from patients’ records of private Dialysis Unit (n=77 and a big General Hospital in a Northern Greece city (n=33 were studied. Demographics, data on medication therapy and vascular access (area, type, dialysis parameters and complications were recorded. Statistical analysis was performed with SPSS 20.0. Results: The sample was 66.7 (±12.5 years old, mainly male (58%, n=58 and on dialysis for 37.3 (±34.3 months. DM was the primary disease of 53% (n=53 of the patients and Hypertension for 13% (n=13,whereas the mean of comorbidities was 5,3 (±2,6. Thirty-seven patients (37% had more than one VA created or placed. On the total of the sample (n=100 156 VA were accessed with the 63% (n=63 of them with arteriovenous fistula (AVF, 35% (n=35 with central venous catheter (CVC and 2% (n=2 with arteriovenous graft (AVG. A statistical significance (U=2560,5, p=0,1 was found regarding the number of VA of the two group of patients (DM=2,2 VA, non DM=1,8. On survival analysis it was found that DM increases the relative risk of “death” of a VA with odds ratio of 1,7 (95% confidence interval 1,1-2,6. Conclusions: DM, as primary disease or co-morbidity, in haemodialysis patients affects negatively the VA survival. Effective blood glucose control, management and methods of puncturing VA play a crucial role in maintaining the VA in DM haemodialysis patients.

    Dipyridamole thallium imaging has been proposed for cardiac risk stratification in patients undergoing peripheral vascular surgery. The purpose of this study was to define the benefit of this investigation in routine preoperative evaluation of these patients. The outcome of 86 patients undergoing vascular surgery procedures was examined in light of preoperative clinical assessment and dipyridamole SPECT thallium imaging (DST). Fifty-one patients (59%) were considered at high risk on clinical grounds, and 22 patients (26%) had perfusion defects. Ten patients suffered a perioperative coronary event, including unstable angina, myocardial infarction, or cardiac death. Seven of the patients with such events were among the 51 clinically high-risk subjects (14%). Three perioperative events occurred in the group of 19 patients with positive DST images who underwent surgery (16%), but the DST test failed to identify 7 patients who suffered coronary events. The frequency of abnormal thallium imaging was similar to the prevalence of angiographically significant coronary disease reported previously at this center, but considerably less than the rate of abnormal thallium imaging in past studies of vascular surgery patients. The application of the test to a low to moderate risk population is probably responsible for its lower predictive accuracy for coronary events. DST is not an ideal routine noninvasive technique for risk stratification in patients undergoing vascular surgery

    Disorders associated with the hepatitis C virus (HCV) have been reported including cardiovascular, metabolic, and central nervous system diseases. Since chronic HCV infections may be curable, their identification as causal contributors to cardiovascular risk could offer new perspectives in the prevention of cardiovascular disease. The aim of this study is to investigate the association between HCV and aortic arch calcification (AAC) and corneal and conjunctival calcification (CCC) in maintenance hemodialysis (MHD) patients; further, we assessed the correlation of CCC with vascular calcification. A total of 100 patients undergoing hemodialysis (HD) in our hospital were included in this study. Patients underwent a complete ocular examination including intraocular pressure, and CCC was looked for by slit lamp and fundoscopy. CCC was graded according to modified Porter and Crombie classification system described by Tokuyama et al. Helical computerized tomographic chest examination was used to evaluate the grading of AAC. Demographic, hematological, biochemical, and dialysis-related data were obtained. There was significant difference between seropositive (n = 51) and seronegative patients (n = 49) regarding grading of AAC and CCC (P <0.001). Significant positive correlation was found between grading of CCC, AAC, age (P <0.001), duration on HD (P <0.001), HCV-antibody positivity (P <0.001), serum calcium level (P <0.001), serum phosphorus level (P <0.001), calcium × phosphorus product (P <0.001), and i-parathormone level (P < 0.001). In addition, CCC grading positively correlated with AAC. Our results suggest that patients undergoing HD infected with the HCV have high degree of CCC, AAC, and mineral metabolism disorder. The strong correlation between CCC and AAC indicates that CCC evaluation is an easy, fast, non-invasive method, and might be used as an indirect indicator to detect vascular calcification in patients undergoing MHD.

    Safe and efficient endovascular aneurysm repair (EVAR) for ruptured abdominal aortic aneurysm (r-AAA) requires advanced infrastructure and surgical expertise not available at all US hospitals. The objective was to assess the impact of regionalizing r-AAA care to centers equipped for both open surgical repair (r-OSR) and EVAR (r-EVAR) by vascular surgeons. A retrospective review of all patients with r-AAA undergoing open or endovascular repair in a 12-hospital region. Patient demographics, transfer status, type of repair, and intraoperative variables were recorded. Outcomes included perioperative morbidity and mortality. Four hundred fifty-one patients with r-AAA were treated from 2002 to 2015. Three hundred twenty-one patients (71%) presented initially to community hospitals (CHs) and 130 (29%) presented to the tertiary medical center (MC). Of the 321 patients presenting to CH, 133 (41%) were treated locally (131 OSR; 2 EVAR) and 188 (59%) were transferred to the MC. In total, 318 patients were treated at the MC (122 OSR; 196 EVAR). At the MC, r-EVAR was associated with a lower mortality rate than r-OSR (20% vs 37%, P = 0.001). Transfer did not influence r-EVAR mortality (20% in r-EVAR presenting to MC vs 20% in r-EVAR transferred, P > 0.2). Overall, r-AAA mortality at the MC was 20% lower than CH (27% vs 46%, P AAA repair to centers equipped for both r-EVAR and r-OSR decreased mortality by approximately 20%. Transfer did not impact the mortality of r-EVAR at the tertiary center. Care of r-AAA in the US should be centralized to centers equipped with available technology and vascular surgeons.

    To examine whether the inter-individual variation in constipation among patients receiving opioids for cancer pain is associated with genetic or non-genetic factors. Cancer patients receiving opioids were included from 17 centers in 11 European countries. Intensity of constipation was reported by 1,568 patients on a four-point categorical scale. Non-genetic factors were included as covariates in stratified regression analyses on the association between constipation and 75 single-nucleotide polymorphisms (SNPs) within 15 candidate genes related to opioid- or constipation-signaling pathways (HTR3E, HTR4, HTR2A, TPH1, ADRA2A, CHRM3, TACR1, CCKAR, KIT, ARRB2, GHRL, ABCB1, COMT, OPRM1, and OPRD1). The non-genetic factors significantly associated with constipation were type of laxative, mobility and place of care among patients receiving laxatives (N=806), in addition to Karnofsky performance status and presence of metastases among patients not receiving laxatives (N=762) (Pconstipation. Five SNPs, rs1800532 in TPH1, rs1799971 in OPRM1, rs4437575 in ABCB1, rs10802789 in CHRM3, and rs2020917 in COMT were associated with constipation (Phospitalization, Karnofsky performance status, presence of metastases, and five SNPs within TPH1, OPRM1, ABCB1, CHRM3, and COMT may contribute to the variability in constipation among cancer patients treated with opioids. Knowledge of these factors may help to develop new therapies and to identify patients needing a more individualized approach to treatment.

    Full Text Available Objective. To assess whether acute stroke patients in rural hospitals receive less occupational therapy and physiotherapy than those in metropolitan hospitals. Design. Retrospective case-control study of health data in patients ≤10 days after stroke. Setting. Occupational therapy and physiotherapy services in four rural hospitals and one metropolitan hospital. Participants. Acute stroke patients admitted in one health district. Main Outcome Measures. Frequency and duration of face-to-face and indirect therapy sessions. Results. Rural hospitals admitted 363 patients and metropolitan hospital admitted 378 patients. Mean age was 73 years. Those in rural hospitals received more face-to-face (p>0.0014 and indirect (p=0.001 occupational therapy when compared to those in the metropolitan hospital. Face-to-face sessions lasted longer (p=0.001. Patients admitted to the metropolitan hospital received more face-to-face (p>0.000 and indirect (p>0.000 physiotherapy when compared to those admitted to rural hospitals. Face-to-face sessions were shorter (p>0.000. Almost all were seen within 24 hours of referral. Conclusions. Acute stroke patients in Australian rural hospital may receive more occupational therapy and less physiotherapy than those in metropolitan hospitals. The dose of therapy was lower than recommended, and the referral process may unnecessarily delay the time from admission to a patient’s first therapy session.

    Chemotherapy-induced nausea and vomiting (CINV) is one of most distressing adverse events during cancer chemotherapy. In breast cancer patients receiving anthracycline and cyclophosphamide (AC) chemotherapy, CINV is poorly controlled. The prevalence of guideline-consistent antiemetic medication and control of CINV were investigated retrospectively in breast cancer patients receiving the first cycle of AC chemotherapy. Risks for CINV were analyzed by the multivariate logistic regression analysis. The effect of olanzapine added to the standard antiemetic medication on the incidence of CINV was subsequently evaluated in separate patients who received the first cycle of AC chemotherapy. Although the guideline-consistent antiemetic medication was performed in all subjects, the control rate of nausea (32%), but not vomiting (78%) was low. Risk analysis indicated that age younger than 55-year-old was a significant factor that reduces the control of both nausea and vomiting. Olanzapine (5 mg/day for 5 days), when added to the standard three-drug antiemetic medication, significantly improved the control of nausea and complete response. CINV was poorly controlled in breast cancer patients receiving AC chemotherapy, in which age younger than 55-year-old was a significant risk for both nausea and vomiting. Olanzapine was effective for improvement of the control of CINV associated with AC chemotherapy. Therefore, care should be taken to prevent CINV in young patients receiving AC chemotherapy by adding olanzapine to the standard three-drug antiemetic medication.

    Cocaine, a powerful vasoconstrictor, induces immune responses including cytokine elevations. Chronic cocaine use is associated with functional brain impairments potentially mediated by vascular pathology. Although the Crack-Cocaine epidemic has declined, its vascular consequences are increasingly becoming evident among individuals with cocaine use disorder of that period, now aging. Paradoxically, during the period when prevention efforts could make a difference, this population receives psychosocial treatment at best. We review major postmortem and in vitro studies documenting cocaine-induced vascular toxicity. PubMed and Academic Search Complete were used with relevant terms. Findings consist of the major mechanisms of cocaine-induced vasoconstriction, endothelial dysfunction, and accelerated atherosclerosis, emphasizing acute, chronic, and secondary effects of cocaine. The etiology underlying cocaine's acute and chronic vascular effects is multifactorial, spanning hypertension, impaired homeostasis and platelet function, thrombosis, thromboembolism, and alterations in blood flow. Early detection of vascular disease in cocaine addiction by multimodality imaging is discussed. Treatment may be similar to indications in patients with traditional risk-factors, with few exceptions such as enhanced supportive care and use of benzodiazepines and phentolamine for sedation, and avoiding β-blockers. Given the vascular toxicity cocaine induces, further compounded by smoking and alcohol comorbidity, and interacting with aging of the crack generation, there is a public health imperative to identify pre-symptomatic markers of vascular impairments in cocaine addiction and employ preventive treatment to reduce silent disease progression.

    Full Text Available Background: Systemic Sclerosis (SSc is characterized by skin thickening, fibrosis and vascular obliteration. The onset and course are heterogeneous. Prominent features include autoimmunity, inflammation and vascular damage. Aim of study: To measure the level of serum Anti-Annexin V antibodies in SSc patients and to study its significance in relation to vascular damage in these patients. Patients and methods: Twenty patients with SSc (12 with diffuse SSc and 8 with the limited form and 10 healthy age and sex matched volunteers as controls were all subjected to routine laboratory testing and immunological profiling including antinuclear, anti-Scl-70, anticentomere, anticardiolipin antibodies and anti-annexin V antibodies titres. Vascular damage was assessed by clinical examination and assessment of the disease activity score, nailfold capillaroscopy and colour flow Doppler of the renal arteries; Doppler echocardiography was used for assessing pulmonary hypertension. Results: Anti-annexin V antibodies were detected in 75% of patients. Comparisons between anti-annexin V in diffuse and limited subgroups showed no significance; however a statistically significant positive correlation was found between Anti-annexin V titre and the degree of vascular damage in SSc patients. Anti-annexin V increased significantly in patients with severe vascular damage in comparison with those less affected (15.3 ± 6.6 vs. 11.25 ± 3.6, P , 0.05. A significant positive correlation was found between Anti-annexin V titre and both the ACL titre (r = 0.79, P , 0.001 and the resistive index of the main renal artery (r = 0.42, P , 0.05. Conclusion: Anti-annexin V antibodies were significantly present in sera of patients with SSc. Patients with more severe forms of vascular damage had higher titres of these antibodies. Anti-annexin V antibodies are a sensitive predictor of vascular damage in SSc and could serve as a useful parameter in discriminating patients with a higher

    Full Text Available Background: Alzheimer dementia (AD and vascular dementia (VD are the most common causes of dementia in the elderly. Depression is an important co-morbid disorder in these diseases, which is often challenging to recognize. We investigated the prevalence of depression in patients with AD and VD and estimated the influence of depression on the health-related quality of life (HrQoL in these patients. Materials and Methods: We evaluated prevalence of depression in consecutively recruited patients with AD or VD (n= 98. Depression was diagnosed according to criteria of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV and scored using the Geriatric Depression Scale. The EuroQol (EQ-5D and visual analogue scale was applied to evaluate HrQoL. The severity of cognitive impairment was measured by the Mini-Mental State Examination (MMSE. Multiple regression analysis was used to identify factors predicting severity of depression. Results: The prevalence of depression in AD/VD was 87%. In comparison to the general population, HrQoL measured on the visual analogue scale was reduced by 54% in patients with AD/VD. In the dimension "anxiety/depression" of the EQ-5D, 81% of patients with AD/VD had moderate or severe problems. Depression showed significant association with reduced HrQoL (P<0.01. Independent predictors of more severe depression were older age, male gender, better MMSE scores and being not married. Conclusions: Depression is a prevalent psychiatric co-morbidity in patients with AD/VD, which is often under-diagnosed being masked by cognitive impairment. Depression is a predictor of reduced HrQoL in elder people with AD/VD. Therefore, they should be screened for presence of depressive symptoms and receive adequate antidepressant treatment.

    To determine risk factors for death in HIV-infected African patients on anti-retroviral therapy (ART). Retrospective Case-control study. The MOH-USAID-AMPATH Partnership ambulatory HIV-care clinics in western Kenya. Between November 2001 and December 2005 demographic, clinical and laboratory data from 527 deceased and 1054 living patients receiving ART were compared to determine independent risk factors for death. Median age at ART initiation was 38 versus 36 years for the deceased and living patients respectively (p100/mm3 (HR=1.553. 95% CI (1.156, 2.087), p<0.003). Patients attending rural clinics had threefold higher risk of dying compared to patients attending clinic at a tertiary referral hospital (p<0.0001). Two years after initiating treatment fifty percent of non-adherent patients were alive compared to 75% of adherent patients. Male gender, WHO Stage and haemoglobin level <10 grams% were associated with time to death while age, marital status, educational level, employment status and weight were not. Profoundly immunosuppressed patients were more likely to die early in the course of treatment. Also, patients receiving care in rural clinics were at greater risk of dying than those receiving care in the tertiary referral hospital.

    Full Text Available Crohn’s disease (CD is a chronic inflammatory bowel disease and its pathogenesis is still not well understood. Previous studies suggested the possibility of the involvement of vascular system, but, todate, the mesenteric circulation has poor been investigated, especially in complicated CD cases requiring colectomy. We investigated the mesenteric circulation in a case-control pilot study, including 19 controls and 7 patients affected by complicated cases of CD. Cases and controls underwent selective angiography of both superior and inferior mesenteric district. Transit time was found either significantly shortened in 2/7 cases (29%, or prolonged 5/7 (71% (P=0.0034 in the superior mesenteric district; P=0.0079 in the inferior mesenteric district, respectively due to the presence of A-V malformations and of a miscellaneous of venous abnormalities, which included thrombosis, hypoplasia and extra-truncular venous malformations. Our study demonstrates the presence of congenital or acquired vascular anomalies in a small sample of CD patients not responder to current treatment and with severe complications. The present pilot study warrants further investigations.

    Cognitive impairment caused by subcortical ischemic vascular disease (SIVD) has been elucidated by many neuroimaging studies. However, little is known regarding the changes in brain functional connectivity networks in relation to the severity of cognitive impairment in SIVD. In the present study, 20 subcortical ischemic vascular cognitive impairment no dementia patients (SIVCIND) and 20 dementia patients (SIVaD) were enrolled; additionally, 19 normal controls were recruited. Each participant underwent a resting-state functional MRI scan. Whole-brain functional networks were analyzed with graph theory and network-based statistics (NBS) to study the functional organization of networks and find alterations in functional connectivity among brain regions. After adjustments for age, gender, and duration of formal education, there were significant group differences for two network functional organization indices, global efficiency and local efficiency, which decreased (NC > SIVCIND > SIVaD) as cognitive impairment worsened. Between-group differences in functional connectivity (NBS corrected, p  impairment worsened, with an increased number of decreased connections between brain regions. We also observed more reductions in nodal efficiency in the prefrontal and temporal cortices for SIVaD than for SIVCIND. These findings indicated a progressively disrupted pattern of the brain functional connectivity network with increased cognitive impairment and showed promise for the development of reliable biomarkers of network metric changes related to cognitive impairment caused by SIVD.

    One of the most specific and critical regulators of angiogenesis is vascular endothelial growth factor (VEGF), which regulates endothelial proliferation, permeability, and survival. Vascular endothelial growth factor is an angiogenic mediator in tumors and has been implicated in the pathogenesis and progression of cancer. Adipose tissue is a major endocrine and it secretes hormones termed adipokines. These factors are derived from adipocytes and include proteins and metabolites such as adiponectin. Recently, adiponectin was also shown to modulate angiogenesis. This study was designed to determine the serum VEGF and adiponectin levels in patients with benign and malignant gynecological diseases and if there was a correlation between serum VEGF and adiponectin. Serum samples, collected fasting before surgery or intervention, were available for total of 114 female patients recorded between October 2006 and December 2008. Diagnosis of benign and malignant gynaecological diseases was established by biopsy. Serum levels VEGF and adiponectin were using commercially available enzyme linked immunosorbent assay (R&D Systems Inc, Minneapolis, MN), respectively. Statistical analysis was performed by using the SPSS 9.0 software package (SPSS, Inc, Chicago, IL). The correlation between serum VEGF and serum Adiponectin was calculated using the Pearson correlation coefficient. P values of benign and malignant gynecological diseases of the patient. Only for serum VEGF levels was a significant difference observed (P = 0.004) between patients with benign and malignant gynecological diseases. A significantly inverse correlation between serum VEGF and adiponectin levels among patients with benign and malignant gynecological diseases was found. Adiponectin level is not correlated with body mass index. This is one of the first report on adiponectin in benign and malignant gynecological diseases. Future studies are needed to address the clinical potential role of adiponectin in cancer.

    Thrombocytopenia is a common finding in patients with cirrhosis and may lead to unnecessary referral for bone marrow (BM) biopsy. To date, the prevalence of cirrhosis in patients with thrombocytopenia who receive BM biopsy is largely unknown. Between fiscal years 2006-2010, 744 patients (≥18 years) who underwent BM biopsies for thrombocytopenia at our hospital were identified retrospectively. 541 patients were excluded who had hematologic malignancies and received chemotherapy. Remaining 203 patients with predominant isolated thrombocytopenia were included in the study. Of 203 patients, 136 (67%) had a normal and 67 (33%) had an abnormal BM examination. Prevalence of cirrhosis in the study population was 35% (95% CI: 28.4-41.9). 51% patients with normal BM were found to have cirrhosis compared to 3% of patients with abnormal BM exam (P < 0.0001). Common causes of cirrhosis were nonalcoholic steatohepatitis (NASH) (47%), followed by alcohol and Hepatitis C virus infection. Idiopathic thrombocytopenia and myelodysplastic syndrome were most frequent causes of thrombocytopenia in patients without cirrhosis. Patients with NASH had higher body mass index (BMI) (33.4 vs. 25.8, P < 0.001) and lower MELD scores (11.1 vs. 16, P = 0.028) when compared to non-NASH patients with cirrhosis. Approximately, one third (35%) of patients with cirrhosis induced thrombocytopenia may undergo unwarranted BM biopsies. Clinical diagnosis of cirrhosis is still a challenge for many physicians, particularly with underlying NASH. We propose cirrhosis to be the prime cause of isolated thrombocytopenia.

    Nonpharmacologic pain management in patients receiving mechanical ventilation support in critical care units is under investigated. Natural sounds may help reduce the potentially harmful effects of anxiety and pain in hospitalized patients. The aim of this study was to examine the effect of pleasant, natural sounds on self-reported pain in patients receiving mechanical ventilation support, using a pragmatic parallel-arm, randomized controlled trial. The study was conducted in a general adult intensive care unit of a high-turnover teaching hospital, in Tehran, Iran. Between October 2011 and June 2012, we recruited 60 patients receiving mechanical ventilation support to the intervention (n = 30) and control arms (n = 30) of a pragmatic parallel-group, randomized controlled trial. Participants in both arms wore headphones for 90 minutes. Those in the intervention arm heard pleasant, natural sounds, whereas those in the control arm heard nothing. Outcome measures included the self-reported visual analog scale for pain at baseline; 30, 60, and 90 minutes into the intervention; and 30 minutes post-intervention. All patients approached agreed to participate. The trial arms were similar at baseline. Pain scores in the intervention arm fell and were significantly lower than in the control arm at each time point (p natural sounds via headphones is a simple, safe, nonpharmacologic nursing intervention that may be used to allay pain for up to 120 minutes in patients receiving mechanical ventilation support.

    Ibrutinib is a Bruton's tyrosine kinase inhibitor that is used for the treatment of lymphoid malignancies, including chronic lymphocytic leukemia (CLL), Waldenström's macroglobulinemia and mantle cell lymphoma (MCL). Several case series have described opportunistic infections among ibrutinib recipients, but the full extent of these infections is unknown. We sought to determine the spectrum of serious infections associated with ibrutinib treatment. We reviewed the electronic medical records of patients with lymphoid malignancies at Memorial Sloan Kettering Cancer Center who received ibrutinib during a five-year period from January 1, 2012 to December 31, 2016. Serious infections were identified by review of the relevant microbiology, clinical laboratory, and radiology data. Risk factors for infection were determined by univariate and multivariate analyses. 378 patients with lymphoid malignancies who received ibrutinib were analyzed. The most common underlying malignancies were CLL and MCL. 84% of patients received ibrutinib as monotherapy. Serious infection developed in 43 patients (11.4%), primarily during the first year of ibrutinib treatment. Of these, 23 (53.5%) developed invasive bacterial infections, and 16 (37.2%) developed invasive fungal infections (IFI). The majority of those who developed IFI on ibrutinib therapy (62.5%) lacked classical clinical risk factors for fungal infection (i.e., neutropenia, lymphopenia, and receipt of corticosteroids). Infection resulted in death in six of the 43 patients (14%). Patients with lymphoid malignancies receiving ibrutinib treatment are at risk for serious infections, including IFI.

    Purpose. A case report evaluating flucytosine dosing in a critically ill patient receiving continuous renal replacement therapy. Summary. This case report outlines an 81-year-old male who was receiving continuous venovenous hemofiltration (CVVH) for acute renal failure and was being treated with flucytosine for the treatment of disseminated Cryptococcus neoformans infection. Due to patient specific factors, flucytosine was empirically dose adjusted approximately 50% lower than intermittent hemodialysis (iHD) recommendations and approximately 33% lower than CRRT recommendations. Peak and trough levels were obtained, which were supratherapeutic, and pharmacokinetic parameters were calculated. The patient experienced thrombocytopenia, likely due to elevated flucytosine levels, and flucytosine was ultimately discontinued. Conclusion. Despite conservative flucytosine dosing for a patient receiving CVVH, peak and trough serum flucytosine levels were supratherapeutic (120 μg/mL at 2 hours and 81 μg/mL at 11.5 hours), which increased drug-related adverse effects. The results indicate that this conservative dosing regimen utilizing the patient's actual body weight was too aggressive. This case report provides insight into flucytosine dosing in CVVH, a topic that has not been investigated previously. Further pharmacokinetic studies of flucytosine dosing in critically ill patients receiving CVVH are needed in order to optimize pharmacokinetic and pharmacodynamic parameters while avoiding toxic flucytosine exposure.

    To prospectively examine the risk of developing Lhermitte’s sign (LS) in patients with lymphoma treated with modern-era chemotherapy followed by consolidation intensity-modulated radiation therapy. We prospectively interviewed all patients with lymphoma who received irradiation to the mediastinum from July 2011 through April 2014. We extracted patient, disease, and treatment-related variables from the medical records of those patients and dosimetric variables from treatment-planning systems and analyzed these factors to identify potential predictors of LS with Pearson chi-square tests. During the study period 106 patients received mediastinal radiation for lymphoma, and 31 (29 %) developed LS. No correlations were found between LS and any of the variables examined, including total radiation dose, maximum point dose to the spinal cord, volume receiving 105 % of the dose, and volumes receiving 5 or 15 Gy. In this group of patients, treatment with chemotherapy followed by intensity-modulated radiation therapy led to 29 % developing LS; this symptom was independent of radiation dose and seemed to be an idiosyncratic reaction. This relatively high incidence could have resulted from prospective use of a structured interview

    Patients receiving long-term parenteral nutrition (PN) are at increased risk of aluminium (Al) toxicity because of bypass of the gastrointestinal tract during PN infusion. Complications of Al toxicity include metabolic bone disease (MBD), Al-associated encephalopathy in adults, and impaired neurological development in preterm infants. Unlike the United States, there are no regulations regarding Al content of large- and small-volume parenterals in Canada. We, therefore, aimed to present our data on plasma Al concentration and Al intake from our cohort of pediatric patients receiving long-term PN. Plasma Al concentration was retrospectively gathered from the patient charts of all 27 patients with intestinal failure (IF) receiving long-term PN at The Hospital for Sick Children, Toronto, Canada, and compared with age- and sex-matched controls recruited for comparison. In addition, Al concentration was measured in PN samples collected from 10 randomly selected patients with IF and used to determine their Al intake. The plasma Al concentration of patients with IF receiving long-term PN was significantly higher than that of control participants (1195 ± 710 vs 142 ± 63 nmol/L; P Parenteral and Enteral Nutrition.

    Vascular malformations (VM) are congenital lesions that can be debilitating and cause significant aesthetic and functional limitations. The chemotherapeutic agent bleomycin has been utilized as a sclerosant, directly injected percutaneously into the VM. Unfortunately, little is known about the benefits and short-term side effects of bleomycin with intralesional injections. An IRB approved, retrospective chart review was performed on patients with VM who had been treated with intralesional bleomycin. Data included type of VM, number of treatments, total bleomycin dose per m², and adverse effects. A questionnaire was administered to available patients to assess subjective outcomes and side effects. Forty-six patients were treated with 141 procedures of bleomycin sclerotherapy for VM. Patient ages ranged from 1 to 20 years (median age 10 years). The median cumulative bleomycin dose was 16.3 units/m²/person (range of 1.7-97.0 units/m²/person). Sixty-three percent of patients were reached for a questionnaire to assess short-term side effects. Ninety percent of patients surveyed were satisfied to very satisfied with the results from the procedure. About 24% of patients experienced transient nausea, vomiting and/or local hyperpigmentation. Bleomycin sclerotherapy can be an effective treatment of VM with repeat exposure with minor risk of short-term side effects, however, long-term risks are of great concern. Further studies are required to assess systemic absorption and long-term risks. © 2018 Wiley Periodicals, Inc.

    The relationship between the antithrombotic and antiplatelet effects of aspirin is complex, since aspirin influences other systems that protect against thrombosis as well as inhibiting platelet function. We investigated possible cumulative effects of low-dose aspirin on vascular production of prostacyclin in patients with documented atherosclerotic cardiovascular disease. Candidates for coronary artery vein graft bypass ingested 20 mg of aspirin daily during the week before surgery, and platelet aggregation, platelet formation of thromboxane A2 (TXA2), aortic and saphenous vein production of prostacyclin (PGI2), and hemostatic status were measured at the time of the bypass surgery. Low-dose aspirin markedly inhibited platelet aggregation responses and reduced TXA2 generation by greater than 90%, effects similar to those observed with much higher doses of aspirin. Both aortic and saphenous vein production of PGI2 were inhibited by 50% compared with PGI2 produced by vascular tissues of control subjects who received no aspirin preoperatively (51 +/- 10 pg 6-keto-PGF1 alpha/mg aortic wet weight [mean +/- SEM] in aspirin-treated subjects vs 130 +/- 16 pg/mg in control subjects, and 71 +/- 8 pg/mg saphenous vein wet weight vs 131 +/- 17 pg/mg). Blood loss at surgery was not significantly increased by preoperative low-dose aspirin as measured by chest tube drainage (754 +/- 229 ml in aspirin-treated subjects vs 645 +/- 271 ml in control subjects), hematocrit nadir (31.2 +/- 1.9% vs 31.8 +/- 1.7%), or transfusions (2.2 +/- 1.3 units of red blood cells vs 2.2 +/- 1.7 units).(ABSTRACT TRUNCATED AT 250 WORDS)

    Objective: To discuss the perioperative nursing care of patients who is going to receive interventional therapy for hepatic artery stenosis after liver transplantation and to provide useful reference for reducing surgery-related complication and for improving the prognosis of patients. Methods: Based on the patient's condition and operative requirement,we provided effective nursing care for 20 patients who were admitted to receive the interventional therapy for hepatic artery stenosis after liver transplantation. The nursing care included preoperative preparation,postoperative nursing and medical guidance at the time of discharge. Results: Interventional therapy was successfully performed in all 20 cases, and no hemorrhagic tendency or acute thrombosis occurred. Marked symptomatic improvement was obtained in all patients. Conclusion: The interventional therapy is an effective treatment for hepatic artery stenosis after liver transplantation. Intensive perioperative nursing care can well prevent the occurrence of surgery-related complications and can surely improve the therapeutic results. (authors)

    We describe four patients with chronic renal failure (CRF) who developedsignificant neurotoxicity after receiving short-term ciprofloxacin. Three ofthem had developed encephalopathy with myoclonic jerks and one patient haddelirium. All patients had advanced chronic renal failure (mean estimatedcreatinine clearance 16+-6 ml/min), although they were not yet on renalreplacement therapy). The mean received dose of ciprofloxacin was 2150+-1300mg and symptoms started to appear after the first 24 hours of drug intake.Investigations ruled out other possible causes of these neurologicalpresentations and withdrawal of ciprofloxacin was followed by completeresolution, after a mean of 8.5+- 4 days. Advanced renal failure in allpatients and underlying neurologic disease in two patients may havepredisposed them to the neurotoxicity. The report of these cases should helpto draw the attention of clinicians to the potential occurrence of theseadverse effects in patients with CRF. (author)

    The aim of this study was to investigate if relaxing music is an effective method of reducing the physiological signs of anxiety in patients receiving mechanical ventilatory support. Few studies have focused on the effect of music on physiological signs of anxiety in patients receiving mechanical ventilatory support. A study-case-control, experimental repeated measures design was used. Sixty patients aged 18-70 years, receiving mechanical ventilatory support and hospitalised in the intensive care unit, were taken as a convenience sample. Participants were randomised to a control group or intervention group, who received 60 minutes of music therapy. Classical music was played to patients using media player (MP3) and headphones. Subjects had physiological signs taken immediately before the intervention and at the 30th, 60th and 90th minutes of the intervention. Physiological signs of anxiety assessed in this study were mean systolic and diastolic blood pressure, pulse rate, respiratory rate and oxygen saturation in blood measured by pulse oxymetry. Data were collected over eight months in 2006-2007. The music group had significantly lower respiratory rates, and systolic and diastolic blood pressure, than the control group. This decrease improved progressively in the 30th, 60th and 90th minutes of the intervention, indicating a cumulative dose effect. Music can provide an effective method of reducing potentially harmful physiological responses arising from anxiety. As indicated by the results of this study, music therapy can be supplied to allay anxiety in patients receiving mechanical ventilation. Nurses may include music therapy in the routine care of patients receiving mechanical ventilation. © 2011 Blackwell Publishing Ltd.

    To elucidate the factors associated with residual gastroesophageal reflux disease (GERD) symptoms in patients receiving proton pump inhibitor (PPI) maintenance therapy in clinical practice. The study included 39 GERD patients receiving maintenance PPI therapy. Residual symptoms were assessed using the Frequency Scale for Symptoms of GERD (FSSG) questionnaire and the Gastrointestinal Symptom Rating Scale (GSRS). The relationships between the FSSG score and patient background factors, including the CYP2C19 genotype, were analyzed. The FSSG scores ranged from 1 to 28 points (median score: 7.5 points), and 19 patients (48.7%) had a score of 8 points or more. The patients' GSRS scores were significantly correlated with their FSSG scores (correlation coefficient = 0.47, P reflux-related symptom scores: 12 ± 1.9 vs 2.5 ± 0.8, P reflux disease patients were significantly lower than those of the other patients (total scores: 5.5 ± 1.0 vs 11.8 ± 6.3, P < 0.05; dysmotility symptom-related scores: 1.0 ± 0.4 vs 6.0 ± 0.8, P < 0.01). Approximately half of the GERD patients receiving maintenance PPI therapy had residual symptoms associated with a lower quality of life, and the CYP2C19 genotype appeared to be associated with these residual symptoms.

    The objectives of this study were to describe the prevalence and types of complementary and alternative medicines (CAMs) used among patients with cancer receiving outpatient chemotherapy in Taiwan. This study was a cross-sectional survey. The study participants were 160 patients with cancer receiving outpatient chemotherapy at a medical center in northern Taiwan. The vast majority of the participants reported CAM use (n = 157, 98.1%). The two most common groups of CAM used were "biologically based therapies" (77.5%) and "mind-body interventions" (60.6%). Fifteen percent (15.3%) of patients took grapeseed and ginseng, which might affect the efficacy of some chemotherapy regimens. Fourteen percent (14.4%) of patients did not know the name of the herbs they took. The most commonly reported reasons for CAM use were to boost the immune system (55.4%) and relieve stress (53.5%). Approximately two thirds of patients (66.2%) had never informed their physicians of CAM use. This survey revealed a high prevalence of CAM use among patients with cancer receiving out-patient chemotherapy in Taiwan. The types of CAM used by patients with cancer in Taiwan differed from those in Western countries. Health professionals need to be cautious about the potential herb-drug interactions.

    Pulmonary vascular resistance (PVR) is the current standard for evaluating reactivity in children with pulmonary arterial hypertension (PAH). However, PVR measures only the mean component of right ventricular afterload and neglects pulsatile effects. We recently developed and validated a method to measure pulmonary vascular input impedance, which revealed excellent correlation between the zero harmonic impedance value and PVR and suggested a correlation between higher-harmonic impedance values and pulmonary vascular stiffness. Here we show that input impedance can be measured routinely and easily in the catheterization laboratory, that impedance provides PVR and pulmonary vascular stiffness from a single measurement, and that impedance is a better predictor of disease outcomes compared with PVR. Pressure and velocity waveforms within the main pulmonary artery were measured during right heart catheterization of patients with normal pulmonary artery hemodynamics (n = 14) and those with PAH undergoing reactivity evaluation (49 subjects, 95 conditions). A correction factor needed to transform velocity into flow was obtained by calibrating against cardiac output. Input impedance was obtained off-line by dividing Fourier-transformed pressure and flow waveforms. Exceptional correlation was found between the indexed zero harmonic of impedance and indexed PVR (y = 1.095x + 1.381, R2 = 0.9620). In addition, the modulus sum of the first 2 harmonics of impedance was found to best correlate with indexed pulse pressure over stroke volume (y = 13.39x - 0.8058, R2 = 0.7962). Among a subset of patients with PAH (n = 25), cumulative logistic regression between outcomes to total indexed impedance was better (R(L)2 = 0.4012) than between outcomes and indexed PVR (R(L)2 = 0.3131). Input impedance can be consistently and easily obtained from pulse-wave Doppler and a single catheter pressure measurement, provides comprehensive characterization of the main components of RV afterload, and

    The Medical Outcome Short Form 36 is commonly used as a generic quality of life measure in the assessment of vascular disease. The Claudication Scale CLAU-S, the PAVK-86 Fragebogen, and the Walking Impairment Questionnaire WIQ are validated disease-specific questionnaires for intermittent claudication. A disease specific tool for critical ischaemia is lacking. Quality of life of patients with peripheral arterial occlusive disease is not only impaired in the physical functioning domains (mobility, self care, activities of daily living), but moreover in their social and emotional wellbeing. This situation worsens under conservative treatment. Angioplasty and operation procedure similar improvements in all dimensions of hrQOL. As radiological interventional procedures just aim to improve hrQOL and do not bring a definite cure for the underlying disease, patients perception of their quality of life should be taken into account both in the indication for angioplasty and for the scientific evaluation of new treatment modalities.

    was 65.2 years. Urinary glucose concentration (UGC) was determined quantitatively in a freshly voided morning urine specimen. RESULTS: The over-all prevalence of peripheral vascular disease (PVD) was 16.5%. Bivariately, high values of UGC were associated with low prevalence of PVD (p...). The predictive value of PVD--together with HbA1c, glomerular filtration rate (GFR) and 10 other possible predictors--was confirmed in a logistic regression analysis with glycosuria (Y/N) as outcome variable (p=0.0004). CONCLUSION: Surprisingly, type 2 diabetic patients with PVD tend not to have glycosuria...... as compared to patients without PVD. PVD may be indicative of generalized atherosclerotic lesions in the major vessels, including the renal arteries. This could lead to a lowering of GFR and thereby of the amount of glucose filtered. Assuming no, or only a minor direct effect of PVD on tubular function...

    Full Text Available OBJECTIVE: This study seeks to understand the drivers of overall patient satisfaction in a predominantly low-income, ethnic-minority population of HIV primary care patients. The study's primary aims were to determine 1 the component experiences which contribute to patients' evaluations of their overall satisfaction with care received, and 2 the relative contribution of each component experience in explaining patients' evaluation of overall satisfaction. METHODS: We conducted a cross-sectional study of 489 adult patients receiving HIV primary care at two clinics in Houston, Texas, from January 13-April 21, 2011. The participation rate among eligible patients was 94%. The survey included 15 questions about various components of the care experience, 4 questions about the provider experience and 3 questions about overall care. To ensure that the survey was appropriately tailored to our clinic population and the list of component experiences reflected all aspects of the care experience salient to patients, we conducted in-depth interviews with key providers and clinic staff and pre-tested the survey instrument with patients. RESULTS: Patients' evaluation of their provider correlated the strongest with their overall satisfaction (standardized β = 0.445, p<0.001 and accounted for almost half of the explained variance. Access and availability, like clinic hours and ease of calling the clinic, also correlated with overall satisfaction, but less strongly. Wait time and parking, despite receiving low patient ratings, did not correlate with overall satisfaction. CONCLUSIONS: The patient-provider relationship far exceeds other component experiences of care in its association with overall satisfaction. Our study suggests that interventions to improve overall patient satisfaction should focus on improving patients' evaluation of their provider.

    Full Text Available In Germany, every child with a life-limiting condition suffering from symptoms that cannot sufficiently be controlled is eligible by law for specialized pediatric palliative home care (SPPHC. It is the aim of this study to describe the demographic and clinical characteristics of children referred to SPPHC and to compare patients with cancer and non-cancer conditions. The prospective multicenter study includes data on 75 children (median age 7.7 years, 50.7% male. The majority had non-cancer conditions (72%. The most common symptoms were cognitive impairment, somatic pain, impairment in communication or swallowing difficulties. Swallowing difficulties, seizures, and spasticity occurred significantly more often in non-cancer patients (p < 0.01. Cancer patients received antiemetics significantly more often (permanent and on demand than non-cancer patients (p < 0.01. Significantly more non-cancer patients had some type of feeding tube (57.3% or received oxygen (33.3% (p < 0.01. Central venous catheters had been fitted in 20% of the patients, mostly in cancer patients (p < 0.001. Tracheostomy tubes (9.3% or ventilation (14.7% were only used in non-cancer patients. In conclusion, patients referred to SPPHC are a diverse cohort with complex conditions including a large range of neurologically originating symptoms. The care of pediatric palliative care patients with cancer is different to the care of non-cancer patients.

    Provision of information to patients and families is a priority of palliative care. Lack of information on symptoms, treatment and disease progress adversely affects patients' and caregivers' abilities to self manage and participate in decision making and care. Qualitative reports of end of life care suggest caregivers seek more information than patients. Ignorance of this need may hamper health promotion strategies and limitation of patient and caregiver morbidity during end of life and bereavement processes. To compare satisfaction of dying patients with information given; to proxy satisfaction estimates on the patient's behalf. Prospective study comparing assessment of satisfaction with information received by nurse, informal caregiver and dying patient (>64 years) in hospital. Assessments made within 24 h, using patient and caregiver versions of the palliative outcome scale (POS). weighted kappa for agreement between proxy and patient. Informal caregivers overestimate dissatisfaction with level of information given compared to patients. Weighted kappa patient versus ICG 0.187 (slight agreement), n = 50. The disparity between patient and proxy information satisfaction reflects the complexity of participatory strategies to limit morbidity at the end of life. Proxy over- estimation of patient dissatisfaction with information received may reflect the caregivers own dissatisfaction. As death approaches, caregivers require more information than patients, their burden increases and they become the interpreter of patient symptoms. Ignorance may lead to overestimation of symptoms, early breakdown of social care, and unplanned admission, risking death other than in the patients preferred place. Meeting caregiver information needs may reduce caregiver burden and improve proxy assessments, reducing patient and caregiver morbidity. © 2015, Published by the BMJ Publishing Group Limited.

Ambulatory blood pressure measurement (ABPM is able to identify patients with masked hypertension (MH underdetected by clinical BP measurement. The benefit of screening for MH in a highrisk population was investigated.Aims: To detect MH in a population with no prior history of hypertension and medically treated for peripheral or coronary arterial disease.Methods: Thirty-eight consecutive patients with peripheral or coronary artery disease documented with arteriography, without a history of hypertension, and with an admission BP < 140/90 mmHg underwent ABPM after discharge. Ambulatory BP ≥ 125/80 mmHg were defined as MH.Results: MH was found in 11 patients (28.9%. The MH group had a mean systolic and diastolic hospitalization BP significantly higher (127 versus 115 mmHg, respectively, P = 0.002 and 76 versus 66 mmHg, P = 0.01, and tended to have a higher admission systolic BP and pulse pressure (127 versus 121 mmHg, respectively, P = 0.07; and 54 versus 46 mmHg, P = 0.06. The first BP measurement on the 24-hour ABPM was significantly higher in the MH group 140 versus 121 mmHg, P = 0.001, for systolic BP and 84 versus 74 mmHg, P = 0.03, for diastolic BP.Conclusions: MH was found in patients with documented and medically treated vascular disease. BP in the prehypertensive range is associated with MH. Systematic screening for MH in this high-risk population requires further investigation.Keywords: blood pressure, monitoring, masked hypertension, vascular disease

    It remains unknown whether taste disorders can be a risk factor for micro- and macro-vascular diseases in patients with abnormal glucose tolerance. A cross-sectional study in a nationally representative samples of 848 and 849 US adults (aged ≥40years) with diabetes or prediabetes who had sweet and salt taste disorders, respectively, from the National Health and Nutrition Examination Survey 2011-2012. Among the study population, 5.7% had sweet taste disorder and 8.6% had salt taste disorder. These data correspond to approximately 1.5 million and 1.8 million individuals with abnormal glucose tolerance aged 40years or older in the US population, respectively. In the adjusted model, sweet taste disorder was significantly associated with complication of ischemic heart disease (adjusted odds ratio [OR], 2.45; 95% confidence interval [CI], 1.03-5.81; P=0.04). Moreover, sweet taste disorder in patients with diabetes was significantly associated with diabetic retinopathy (adjusted OR, 2.89; 95% CI, 1.09-7.69; P=0.03) and diabetic nephropathy (adjusted OR, 3.17; 95% CI, 1.07-9.36; P=0.03). Meanwhile, salt taste disorder was not significantly associated with diabetic retinopathy, diabetic nephropathy, ischemic heart disease, or stroke. Total sugar intake was significantly higher in patients with sweet taste disorder than in those without it, whereas total daily intake of carbohydrate did not differ significantly. No significant association was observed between salt taste disorder and daily intake of sodium after multivariate analysis. Sweet taste disorder in patients with abnormal glucose tolerance was associated with increased sugar intake and vascular complications. Copyright © 2016 The Authors.

    This study aimed to assess the cognitive functions and cerebral blood flow measured with arterial spin labeling (ASL) and their possible correlations with vascular age in untreated middle-aged patients with grade 1-2 essential arterial hypertension (EAH). We examined 73 subjects aged 40-59 years (33 with EAH and 40 healthy volunteers [controls]). Neuropsychological assessment included Montreal Cognitive Assessment (MoCA), Trail Making test (part A and part B), Stroop Color and Word Test, verbal fluency test (phonemic verbal fluency and semantic verbal fluency), 10‑item word list learning task. All subjects underwent brain MRI. MRI protocol included ASL. Vascular age was calculated by two techniques - using Framingham Heart Study risk tables and SCORE project scales. Patients with EAH had lower performance on phonemic verbal fluency test and lower mean MoCA score (29.2±1.4 vs. 28.1±1.7 points) compared to controls (13.4±3.2, р=0.002; 29.2±1.4, p=0.001, respectively). White matter hyperintensities (WMH) were present in 7.5 % controls and in 51.5 % EAH patients (р=0.0002). Cerebral blood flow (CBF) in EAH patients was lower in both right (39.1±5.6 vs. 45.8±3.2 ml / 100 g / min) and left frontal lobes of the brain (39.2±6.2 и 45.2±3.6 ml / 100 g / min, respectively) compared to controls (р.

    Hepatocellular carcinoma (HCC) is a common malignant tumor in China, and early diagnosis is critical for patient outcome. In patients with HCC, it is mostly based on liver cirrhosis, developing from benign regenerative nodules and dysplastic nodules to HCC lesions, and a better understanding of its vascular supply and the hemodynamic changes may lead to early tumor detection. Angiogenesis is essential for the growth of primary and metastatic tumors due to changes in vascular perfusion, blood volume and permeability. These hemodynamic and physiological properties can be measured serially using functional computed tomography perfusion (CTP) imaging and can be used to assess the growth of HCC. This study aimed to clarify the physiological characteristics of tumor angiogenesis in cirrhotic liver disease by this fast imaging method. CTP was performed in 30 volunteers without liver disease (control subjects) and 49 patients with liver disease (experimental subjects: 27 with HCC and 22 with cirrhosis). All subjects were also evaluated by physical examination, laboratory screening and Doppler ultrasonography of the liver. The diagnosis of HCC was made according to the EASL criteria. All patients underwent contrast-enhanced ultrasonography, pre- and post-contrast triple-phase CT and CTP study. A mathematical deconvolution model was applied to provide hepatic blood flow (HBF), hepatic blood volume (HBV), mean transit time (MTT), permeability of capillary vessel surface (PS), hepatic arterial index (HAI), hepatic arterial perfusion (HAP) and hepatic portal perfusion (HPP) data. The Mann-Whitney U test was used to determine differences in perfusion parameters between the background cirrhotic liver parenchyma and HCC and between the cirrhotic liver parenchyma with HCC and that without HCC. In normal liver, the HAP/HVP ratio was about 1/4. HCC had significantly higher HAP and HAI and lower HPP than background liver parenchyma adjacent to the HCC. The value of HBF at the tumor

    The purpose of this study was to investigate the incidence of fosaprepitant-associated infusion site adverse events (ISAEs) among a cohort of breast cancer patients receiving doxorubicin/cyclophosphamide (AC) chemotherapy. A retrospective review of electronic medical record (EMR) data was performed for all patients who were initiated on AC from January 2011 to April 2012. Data collected included baseline demographics, antiemetic regimen, documentation of ISAEs, and type of intravenous (IV) access. Descriptive statistics (mean and standard deviation or percentages) were summarized overall, by type of IV access and initial antiemetic given. Among the 148 patients included in this analysis, 98 initially received fosaprepitant and 44 received aprepitant. The incidence of ISAEs associated with fosaprepitant administration was 34.7 % (n=34), while the incidence of aprepitant-associated ISAEs was 2.3 % (n=1). All ISAEs were associated with peripheral IV access. The most commonly reported ISAEs were infusion site pain (n=26), erythema (n=22), swelling (n=12), superficial thrombosis (n=8), infusion site hives (n=5), and phlebitis/thrombophlebitis (n=5). Twenty-six patients experienced more than one type of ISAE. The incidence and severity of ISAEs associated with fosaprepitant administration among a group of patients receiving AC chemotherapy are significant and appreciably higher than what has been previously reported.

    Full Text Available Purpose. A case report evaluating flucytosine dosing in a critically ill patient receiving continuous renal replacement therapy. Summary. This case report outlines an 81-year-old male who was receiving continuous venovenous hemofiltration (CVVH for acute renal failure and was being treated with flucytosine for the treatment of disseminated Cryptococcus neoformans infection. Due to patient specific factors, flucytosine was empirically dose adjusted approximately 50% lower than intermittent hemodialysis (iHD recommendations and approximately 33% lower than CRRT recommendations. Peak and trough levels were obtained, which were supratherapeutic, and pharmacokinetic parameters were calculated. The patient experienced thrombocytopenia, likely due to elevated flucytosine levels, and flucytosine was ultimately discontinued. Conclusion. Despite conservative flucytosine dosing for a patient receiving CVVH, peak and trough serum flucytosine levels were supratherapeutic (120 μg/mL at 2 hours and 81 μg/mL at 11.5 hours, which increased drug-related adverse effects. The results indicate that this conservative dosing regimen utilizing the patient’s actual body weight was too aggressive. This case report provides insight into flucytosine dosing in CVVH, a topic that has not been investigated previously. Further pharmacokinetic studies of flucytosine dosing in critically ill patients receiving CVVH are needed in order to optimize pharmacokinetic and pharmacodynamic parameters while avoiding toxic flucytosine exposure.

    Over the past 2 decades, significant advances have been made in the management of infections after transplant; however, transplant recipients are still at high risk of infectious complications. This study aimed to evaluate the prevalence of bacterial infections and antimicrobial resistance patterns in kidney transplant recipients. This cross-sectional study included 356 patients who received kidney transplants, regardless of the underlying disease, from 2013 to 2015 at the Montaserieh Transplant Hospital (Mashhad, Iran). Clinical samples collected from patients were sent to the microbiology laboratory for culture processing. Typing of bacteria was conducted, and susceptibility testing was performed according to the Clinical and Laboratory Standards Institute guideline by use the of disk diffusion agar method. Data were then analyzed by SPSS software (SPSS: An IBM Company, IBM Corporation, Armonk, NY, USA) using chi-square test. Among 356 kidney recipients (206 men and 150 women), 115 (32.3%) received transplants from living donors and 241 (67.7%) received transplants from deceased donors. Of 356 total patients, 112 patients (31.5%) had an infection at various times after transplant. The most common gram-negative and gram-positive isolated bacteria were Escherichia coli and coagulase-negative Staphylococcus, with prevalence rates of 66.1% and 48.6%. Most of the isolates were resistant against selected antibiotics. Because of the high prevalence of infection among transplant patients, infection prevention should receive more attention, and antibiotic susceptibility should be determined before treatment.

    Pediatric limb reconstruction after resection of a malignant tumor presents specific challenges. Multiple surgical techniques have been used to treat these patients. This paper describes a staged surgical technique for the reconstruction of large distal femoral defects due to tumor resection in skeletally immature patients. Three pediatric patients with osteosarcoma of the distal femur underwent staged reconstruction. Neoadjuvant chemotherapy was followed by en bloc tumor resection and immediate reconstruction of the distal femoral defect with a vascularized free fibular autograft utilizing a unique A-frame construct combined with intramedullary nail fixation. The second stage was a planned gradual lengthening of the healed construct, over a custom-made magnetically driven expandable intramedullary nail. All patients achieved bony union and satisfactory length with minimal complications. The patients all returned to full, unlimited physical activities. The early results confirm that the described technique is a safe and reliable procedure for the reconstruction of large femoral defects in pediatric patients with osteosarcoma. Level IV-therapeutic.

    The patient's perception and satisfaction are increasingly considered as a useful factor in the assessment of competency of health care providers and quality of care. However, these patient focused assessments are largely ignored when assessing health care outcomes. The study assessed the perception and satisfaction of patients receiving antiretroviral therapy (ART) with pharmaceutical services received in outpatient HIV treatment settings. Seventeen HIV treatment centres in Nigeria. This cross-sectional survey included 2,700 patients randomly selected from 26,319 HIV patients on ART, who received pharmaceutical services in the study setting. A study-specific Likert-type instrument was administered to the participants at point of exit from the pharmacy. Midpoint of the 5-point scale was computed and scores above it were regarded as positive while below as negative. Chi-square was used for inferential statistics. All reported p values were 2-sided at 95 % confidence interval (CI). Patient satisfaction with pharmaceutical services. Of 2,700 patients sampled, data from 1,617 (59.9 %) were valid for analysis; 62.3 % were aged 26-40 years and 65.4 % were females. The participants had received pharmaceutical services for a mean duration of 25.2 (95 % CI 24.3-26.1) months. Perception of participants regarding the appearance of pharmacy was positive while that regarding the pharmacists' efforts to solve patients' medication related problems was negative. The participants' rating of satisfaction with the waiting time to access pharmaceutical services was negative; the satisfaction decreases with increasing waiting time.

    Despite the theoretical risk of serotonin toxicity (ST) with linezolid, “real-world” clinical evaluations of the risk of ST in patients receiving linezolid have been limited to case reports and noncomparator studies. An observational, matched-cohort study was conducted to evaluate the risk of ST among hospitalized patients who received linezolid or vancomycin at the Upstate New York Veterans Affairs Healthcare Network (Veterans Integrated Service Network 2 [VISN-2]). Matching criteria included VISN-2 hospital, hospital ward, prior hospital length of stay, age, and baseline platelet counts. The patients' electronic medical records were evaluated for symptoms consistent with ST and the Hunter serotonin toxicity criteria (HSTC) using an intensive, natural word search algorithm. The study included 251 matched pairs. Demographics and comorbidities were similar between groups. Over half of the study population received at least one concurrent medication with serotonergic activity. Receipt of agents with serotonergic activity was more pronounced in the vancomycin group, and the higher frequency was due to concomitant antihistamine and antiemetic use. Antidepressant use, including selective serotonin reuptake inhibitors (SSRIs), was similar between groups. No patients in either group were found to meet the criteria using the word search algorithm for ST. Fewer linezolid patients than vancomycin patients met the HSTC overall (3.2% versus 8.8%) and when stratified by receipt of a concurrent serotonergic agent (4.3% versus 12.4%). Of the patients meeting the HSTC, most had past or present comorbidities that may have contributed to or overlapped the HSTC. This study of hospitalized patients revealed comparably low frequencies of adverse events potentially related to ST among patients who received linezolid or vancomycin. PMID:24041888

    This research investigated the information needs of patients receiving ED procedural sedation to determine the best format to consistently deliver key information in a way acceptable to all involved. Of particular interest was the question concerning patients' need for receiving written information. A descriptive exploratory study gathered qualitative data through face-to-face interviews and focus groups involving patients, nurses and medical staff. Individual interviews were conducted with eight adult patients following procedural sedation. They identified very few gaps in terms of specific information they needed pertaining to procedural sedation and rejected the need for receiving information in a written format. Their information needs related to a central concern for safety and trust. Focus groups, reflecting on the findings from patients, were conducted with five ED nurses and four emergency medicine consultants/registrars who regularly provided procedural sedation. Themes that emerged from the analysis of data from all three groups identified the issues concerning patient information needs as being: competence and efficiency of staff; explanations of procedures and progress; support person presence; and medico-legal issues. The research confirms that the quality of the patient's ED experience, specifically related to procedural sedation, is enhanced by ED staff, especially nurses, providing them with ongoing and repeated verbal information relevant to their circumstances.

    Background Pulmonary vascular resistance (PVR) is the current standard for evaluating reactivity in children with pulmonary arterial hypertension (PAH). However, PVR measures only the mean component of right ventricular afterload and neglects pulsatile effects. We recently developed and validated an method to measure pulmonary vascular input impedance, which revealed excellent correlation between the zero-harmonic impedance value and PVR, and suggested a correlation between higher harmonic impedance values and pulmonary vascular stiffness (PVS). Here we show that input impedance can be measured routinely and easily in the catheterization laboratory, that impedance provides PVR and PVS from a single measurement, and that impedance is a better predictor of disease outcomes compared to PVR. Methods Pressure and velocity waveforms within the main PA were measured during right-heart catheterization of patients with normal PA hemodynamics (n=14) and those with PAH undergoing reactivity evaluation (49 subjects; 95 conditions). A correction factor needed to transform velocity into flow was obtained by calibrating against cardiac output. Input impedance was obtained off-line by dividing Fourier-transformed pressure and flow waveforms. Results Exceptional correlation was found between the indexed zero harmonic of impedance and indexed PVR (y=1.095·x+1.381, R2=0.9620). Additionally, the modulus sum of the first two harmonics of impedance was found to best correlate with indexed pulse pressure over stroke volume (PP/SV) (y=13.39·x-0.8058, R2=0.7962). Amongst a subset of PAH patients (n=25), cumulative logistic regression between outcomes to total indexed impedance was better (RL2=0.4012) than between outcomes and indexed PVR (RL2=0.3131). Conclusions Input impedance can be consistently and easily obtained from PW Doppler and a single catheter pressure measurement, provides comprehensive characterization of the main components of RV afterload, and better predicts patient

    Recent advances in resting-state functional MRI have revealed altered functional networks in Alzheimer's disease (AD), especially those of the default mode network (DMN) and central executive network (CEN). However, few studies have evaluated whether small vessel disease (SVD) or combined amyloid and SVD burdens affect the DMN or CEN. The aim of this study was to evaluate whether SVD or combined amyloid and SVD burdens affect the DMN or CEN. In this cross-sectional study, we investigated the resting-state functional connectivity within DMN and CEN in 37 Pittsburgh compound-B (PiB)(+) AD, 37 PiB(-) subcortical vascular dementia (SVaD), 13 mixed dementia patients, and 65 normal controls. When the resting-state DMN of PiB(+) AD and PiB(-) SVaD patients were compared, the PiB(+) AD patients displayed lower functional connectivity in the inferior parietal lobule while the PiB(-) SVaD patients displayed lower functional connectivity in the medial frontal and superior frontal gyri. Compared to the PiB(-) SVaD or PiB(+) AD, the mixed dementia patients displayed lower functional connectivity within the DMN in the posterior cingulate gyrus. When the resting-state CEN connectivity of PiB(+) AD and PiB(-) SVaD patients were compared, the PiB(-) SVaD patients displayed lower functional connectivity in the anterior insular region. Compared to the PiB(-) SVaD or PiB(+) AD, the mixed dementia patients displayed lower functional connectivity within the CEN in the inferior frontal gyrus. Our findings suggest that in PiB(+) AD and PiB(-) SVaD, there is divergent disruptions in resting-state DMN and CEN. Furthermore, patients with combined amyloid and SVD burdens exhibited more disrupted resting-state DMN and CEN than patients with only amyloid or SVD burden.

    Full Text Available The cardio-ankle vascular index (CAVI is used to test vascular function and is an arterial stiffness marker and potential predictor of cardiovascular events. This study aimed to analyze the relation between objective indices of diabetic polyneuropathy (DPN and the CAVI. One hundred sixty-six patients with type 2 diabetes mellitus were included in this study. We used nerve conduction studies (NCSs and the coefficient of variation of the R-R interval to evaluate DPN. We estimated arteriosclerosis by the CAVI. Simple and multiple linear regression analyses were performed between neuropathy indices and the CAVI. In univariate analysis, the CAVI showed significant associations with sural sensory nerve conduction velocity and median F-wave conduction velocity. Multiple linear regression analysis for the CAVI showed that sural nerve conduction velocity and median F-wave conduction velocity were significant explanatory variables second only to age. In multiple linear regression analysis for sural nerve conduction velocity among neuropathy indices, the CAVI remained the most significant explanatory variable. In multiple linear regression analysis for median nerve F-wave conduction velocity among neuropathy indices, the CAVI remained the second most significant explanatory variable following HbA1c. These results suggest a close relationship between macroangiopathy and DPN.

    To investigate the relationship between effective fentanyl sublingual spray (FSS) doses for breakthrough cancer pain (BTCP) and around-the-clock (ATC) transdermal fentanyl patch (TFP). Adults tolerating ATC opioids received open-label FSS for 26 days, followed by a 26-day double-blind phase for patients achieving an effective dose (100-1600 µg). Out of 50 patients on ATC TFP at baseline, 32 (64%) achieved an effective dose. FSS effective dose moderately correlated with mean TFP dose (r = 0.4; p = 0.03). Patient satisfaction increased during the study. Common adverse event included nausea (9%) and peripheral edema (9%). FSS can be safely titrated to an effective dose for BTCP in patients receiving ATC TFP as chronic cancer pain medication. ClinicalTrials.gov identifier: NCT00538850.

    Prior studies demonstrate mitochondrial dysfunction with increased reactive oxygen species generation in peripheral blood mononuclear cells in diabetes mellitus. Oxidative stress-mediated damage to mitochondrial DNA promotes atherosclerosis in animal models. Thus, we evaluated the relation of mitochondrial DNA damage in peripheral blood mononuclear cells s with vascular function in patients with diabetes mellitus and with atherosclerotic cardiovascular disease. We assessed non-invasive vascular function and mitochondrial DNA damage in 275 patients (age 57 ± 9 years, 60 % women) with atherosclerotic cardiovascular disease alone (N = 55), diabetes mellitus alone (N = 74), combined atherosclerotic cardiovascular disease and diabetes mellitus (N = 48), and controls age >45 without diabetes mellitus or atherosclerotic cardiovascular disease (N = 98). Mitochondrial DNA damage measured by quantitative PCR in peripheral blood mononuclear cells was higher with clinical atherosclerosis alone (0.55 ± 0.65), diabetes mellitus alone (0.65 ± 1.0), and combined clinical atherosclerosis and diabetes mellitus (0.89 ± 1.32) as compared to control subjects (0.23 ± 0.64, P < 0.0001). In multivariable models adjusting for age, sex, and relevant cardiovascular risk factors, clinical atherosclerosis and diabetes mellitus remained associated with higher mitochondrial DNA damage levels (β = 0.14 ± 0.13, P = 0.04 and β = 0.21 ± 0.13, P = 0.002, respectively). Higher mitochondrial DNA damage was associated with higher baseline pulse amplitude, a measure of arterial pulsatility, but not with flow-mediated dilation or hyperemic response, measures of vasodilator function. We found greater mitochondrial DNA damage in patients with diabetes mellitus and clinical atherosclerosis. The association of mitochondrial DNA damage and baseline pulse amplitude may suggest a link between mitochondrial dysfunction and excessive small artery pulsatility with potentially adverse microvascular impact.

    The ratio of the area under the free (unbound) concentration-time curve to minimum inhibitory concentration (fAUC/MIC) was proposed to be the pharmacokinetic/pharmacodynamic index most strongly linked to the antibacterial effect of colistin against Acinetobacter baumannii. A retrospective study of patients who received colistin to treat pneumonia caused by extensively drug-resistant (XDR) A. baumannii over a 4-year period was performed to assess the impact of the colistin MIC on mortality. A total of 227 patients were included in the analysis. The 7-day and 14-day mortality rates of patients with XDR A. baumannii pneumonia receiving colistin therapy were 15.0% and 23.8%, respectively. In the multivariate analysis, Acute Physiology and Chronic Health Evaluation (APACHE) II score, days from index culture to first dose of colistin, underlying tumour and septic shock at presentation were independent predictors of mortality in patients with XDR A. baumannii pneumonia receiving colistin therapy. In the univariate analysis, the colistin dose based on ideal body weight (IBW) correlated with patient outcome. Therefore, the use of IBW appeared to be more appropriate to calculate the colistin dosage. In addition, these results highlight the clinical significance of colistin MIC in patients with XDR A. baumannii pneumonia receiving colistin therapy. Although MICs were in the 'susceptible' range, patients infected with isolates with high colistin MICs showed a poorer clinical response rate than patients infected with isolates with low colistin MICs. Further clinical studies are needed to evaluate the roles of colistin MIC for predicting mortality in XDR A. baumannii pneumonia with a high colistin MIC.

    ESRD requiring dialysis is associated with increased morbidity and mortality rates, including increased rates of cognitive impairment, compared with the general population. About one quarter of patients receiving dialysis choose to discontinue dialysis at the end of life. Advance directives are intended to give providers and surrogates instruction on managing medical decision making, including end of life situations. The prevalence of advance directives is low among patients receiving dialysis. Little is known about the contents of advance directives among these patients with advance directives. We retrospectively reviewed the medical records of all patients receiving maintenance in-center hemodialysis at a tertiary academic medical center between January 1, 2007 and January 1, 2012. We collected demographic data, the prevalence of advance directives, and a content analysis of these advance directives. We specifically examined the advance directives for instructions on management of interventions at end of life, including dialysis. Among 808 patients (mean age of 68.6 years old; men =61.2%), 49% had advance directives, of which only 10.6% mentioned dialysis and only 3% specifically addressed dialysis management at end of life. Patients who had advance directives were more likely to be older (74.5 versus 65.4 years old; Phydration (34.3%), and pain management (43.4%) than dialysis (10.6%). Although one-half of the patients receiving dialysis in our study had advance directives, end of life management of dialysis was rarely addressed. Future research should focus on improving discernment and documentation of end of life values, goals, and preferences, such as dialysis-specific advance directives, among these patients.

    PurposeTo evaluate the safety and efficacy of transarterial embolization of life-threatening arterial rupture in patients with vascular Ehlers–Danlos syndrome (vEDS) in a single tertiary referral center.MethodsWe retrospectively analyzed transarterial embolization for vEDS performed at our institution from 2000 to 2012. The indication of embolization was spontaneous arterial rupture or pseudoaneurysm with acute bleeding. All interventions used a percutaneous approach through a 5F or less introducer sheath. Embolic agents were microcoils and glue in 3 procedures, glue alone in 2, and microcoils alone in 2.ResultsFive consecutive vEDS patients were treated by 7 embolization procedures (4 women, mean age 29.8 years). All procedures were successfully performed. Two patients required a second procedure for newly arterial lesions at a different site from the first procedure. Four of the five patients were still alive after a mean follow-up of 19.4 (range 1–74.7) months. One patient died of multiple organ failure 2 days after procedure. Minor procedural complications were observed in 3 procedures (43 %), all directly managed during the same session. Remote arterial lesions occurred after 3 procedures (43 %); one underwent a second embolization, and the other 2 were observed conservatively. Puncture site complication was observed in only one procedure (14 %).ConclusionEmbolization for vEDS is a safe and effective method to manage life-threatening arterial rupture.

    We measured vascular endothelial growth factor (VEGF) levels in tear fluid and serum in patients with retinal vein occlusion (RVO). Eight patients with RVO due to secondary macular oedema were examined. VEGF levels were measured by enzyme-linked immunosorbent assay. All patients had a full ophthalmic examination (visual acuity, slit lamp biomicroscopy, perimetry, and fluorescein angiography). Central retinal thickness (CRT) was examined using optical coherence tomography (OCT). Tear and serum samples were collected and examinations were performed at diagnosis and 1 and 4 weeks later. VEGF levels in the tears of RVO eyes were significantly higher than in fellow eyes at diagnosis and after both 1 and 4 weeks (paired t test, p1 = 0.01, p2 = 0.02, p3 = 0.006). We found a weak but significant positive correlation between VEGF levels in tear fluid and serum of patients with RVO (r = 0.21), while this correlation tended to be stronger between the fellow eyes and serum levels (r = 0.33). To the best of our knowledge, we are the first to report an increased level of VEGF in the tear fluid of patients with RVO. Alterations of VEGF levels in tears may be useful for determining stages of RVO. This non-invasive and objective method may also be helpful for estimating the severity of macular oedema and efficacy of treatment.

    We report results of Iotrolan CT-cisternography on 41 demented patients (13 males and 28 females) to find 'occult normal pressure hydrocephalus'. These patients were suspected to have CSF flow disturbance from clinical symptoms and simple brain CT scan findings. Their average age, duration of dementia, and score of Hasegawa's dementia scale (HDS) were 76.2 years, 5.9 years, 9.5/32.5,respectively. Before performing CT-cisternography, clinical diagnosis for their dementia were vascular dementia in 18 patients. Alzheimer type dementia in 12, suspect of NPH in 5, and other diagnoses in 6. From the results of cisternography, we found 13 patients with CSF flow disturbance (contrast material remained in the ventricle more than 48 hours after injection), and 17 patients with normal CSF flow. The former showed lower scores of HDS, higher urinary incontinence scores and smaller areas of the interhemispheric fissure on CT scan than the latter. But the former showed no significant difference from the latter in the average age, duration of dementia and width of the ventricles. (author)

    This paper reports the use of different vascular access devices and the incidence of intravascular catheter-related infection (CRI) in patients receiving intravenous antibiotics for infective endocarditis (IE). To examine whether rates of infection vary with type of vascular access device, and assess the impact of CRI on mortality in IE. A prospective observational service evaluation of all inpatients who received intravenous antibiotics for IE was performed. In total, 114 inpatients were evaluated. All cases of CRI [including exit-site infection, intravascular catheter-related bloodstream infection (CRBSI) and mortality] were recorded. Tunnelled and non-tunnelled central venous catheters (CVCs), and peripherally inserted cannulae were used for antibiotic delivery. There were 15 episodes of CRI, 11 of which were CRBSI (all associated with CVC use). The remainder comprised uncomplicated exit-site infections. Use of tunnelled CVCs [hazard ratio (HR) 16.95, 95% confidence interval (CI) 2.13-134.93; P = 0.007] and non-tunnelled CVCs (HR 24.54, 95% CI 2.83-212.55; P = 0.004) was associated with a significantly increased risk of CRI. Risk of mortality increased significantly with Staphylococcus aureus as the cause of IE (P < 0.001) and CRBSI (P = 0.034). Risk of CRI in patients with IE is linked to the type of vascular access device used. Rates of CRBSI were greatest with CVCs, while peripheral venous cannulae were not associated with CRBSI or serious sequelae. Many patients (40%) tolerated complete treatment courses delivered via peripheral cannulae. These findings confirm the importance of device selection in reducing the risk of CRI; a potentially modifiable variable that impacts on outcome and mortality in IE.

    Purpose: We investigated intrahepatic vascular changes in patients undergoing right portal vein ligation (PVL) or portal vein embolization (PVE) in conjunction with the ensuing hypertrophic response and function of the left liver lobe. Methods: Between December 2008 and October 2011, 7 patients underwent right PVL and 14 patients PVE. Computed tomographic (CT) volumetry to assess future remnant liver (FRL) and functional hepatobiliary scintigraphy were performed in all patients before and 3 weeks after portal vein occlusion. In 18 patients an intraoperative portography was performed to assess perfusion through the occluded portal branches. Results: In all patients after initially successful PVL, reperfused portal veins were observed on CT scan 3 weeks after portal occlusion. This was confirmed in all cases during intraoperative portography. Intrahepatic portoportal collaterals were identified in all patients in the PVL group and in one patient in the PVE group. In all other PVE patients, complete occlusion of the embolized portal branches was observed on CT scan and on intraoperative portography. The median increase of FRL volume after PVE was 41.6 % (range 10-305 %), and after PVL was only 8.1 % (range 0-102 %) (p = 0.179). There were no differences in FRL function between both groups. Conclusion: Preoperative PVE and PVL are both methods to induce hypertrophy of the FRL in anticipation of major liver resection. Compared to PVE, PVL seems less efficient in inducing hypertrophy of the nonoccluded left lobe. This could be caused by the formation of intrahepatic portoportal neocollateral vessels, through which the ligated portal branches are reperfused within 3 weeks.

    Resuscitation of patients presenting with hemorrhagic shock after major trauma has evolved to incorporate multiple strategies to maintain tissue perfusion and oxygenation while managing coagulation disorders. We aimed to study changes across time in long-term outcomes in patients with major trauma. A retrospective observational study in a single major trauma center in Australia was conducted. We included all patients with major trauma and massive blood transfusion within the first 24 h during a 6-year period (from 2006 to 2011). The main outcome measures were Glasgow Outcome Score-Extended (GOSE) and work capacity at 6 and 12 months. There were 5,915 patients with major trauma of which 365 (6.2%; 95% confidence interval [95% CI], 5.6 - 6.8) received a massive transfusion. The proportion of major trauma patients receiving a massive transfusion decreased across time from 8.2% to 4.4% (P GOSE at 6 months, and 44% unfavorable GOSE at 12 months. Massive transfusion was independently associated with unfavorable outcomes at 6 months after injury (adjusted odds ratio, 1.56; 95% CI, 1.05 - 2.31) but not at 12 months (adjusted odds ratio, 0.85; 95% CI, 0.72 - 1.01). A significant reduction in massive transfusion rates was observed. Unfavorable long-term outcomes among patients receiving a massive transfusion after trauma were frequent with a substantial proportion of survivors experiencing poor functional status 1 year after injury.

    To assess the benefit of proactive palliative medicine consultation for delineation of goals of care and quality-of-life preferences before implantation of left ventricular assist devices as destination therapy (DT). We retrospectively reviewed the cases of patients who received DT between January 15, 2009, and January 1, 2010. Of 19 patients identified, 13 (68%) received proactive palliative medicine consultation. Median time of palliative medicine consultation was 1 day before DT implantation (range, 5 days before to 16 days after). Thirteen patients (68%) completed advance directives. The DT implantation team and families reported that preimplantation discussions and goals of care planning made postoperative care more clear and that adverse events were handled more effectively. Currently, palliative medicine involvement in patients receiving DT is viewed as routine by cardiac care specialists. Proactive palliative medicine consultation for patients being considered for or being treated with DT improves advance care planning and thus contributes to better overall care of these patients. Our experience highlights focused advance care planning, thorough exploration of goals of care, and expert symptom management and end-of-life care when appropriate.

    Patients dependent on parenteral nutrition (PN) are among a group at risk of developing iodine deficiency. Supplementation with iodine in this population has been debated in a number of studies, resulting in variable clinical practices. The Committee on Clinical Practice Issues of the American Society for Clinical Nutrition recommends a dose of 1 mcg/kg/d of parenteral iodine for patients receiving PN. At our institution, PN trace elements do not include iodine, although this is not the case internationally. Our study sought to assess iodine levels and thyroid function in a cohort of PN-dependent pediatric patients. A retrospective analysis studied 32 pediatric patients with a variety of medical diagnoses who received PN as a primary means of nutrition for 6 months or longer. Patients received variable proportions of their total caloric intake as PN, which ranged from 14%-100%. Iodine and thyroid function levels were obtained by serum sampling. No patient in our cohort of 32 demonstrated thyroid dysfunction or developed iodine deficiency. The length of time on PN and the percentage of total nutrition intake as PN were not associated with iodine levels (P Parenteral and Enteral Nutrition.

    Visit-to-visit blood pressure variability (BPV) is a simple surrogate marker for the development of atherosclerotic diseases, cardiovascular and all-cause mortality. Nevertheless, the relative prognostic value of BPV in comparison with other established vascular assessments remain uncertain. We prospectively followed-up 656 high-risk patients with diabetes or established cardiovascular or cerebrovascular diseases for the occurrence of major adverse cardiovascular events (MACEs). Baseline brachial endothelial function, carotid intima-media thickness (IMT) and plaque burden, ankle-brachial index and arterial stiffness were determined. Visit-to-visit BPV were recorded during a mean 18 ± 9 outpatient clinic visits. After a mean 81 ± 12 month's follow-up, 123 patients (19%) developed MACEs. Patients who developed a MACE had significantly higher systolic BPV, more severe endothelial function, arterial stiffness and systemic atherosclerotic burden compared to patients who did not develop a MACE (all Parea under receiver operating characteristic curve (AUC) 0.69 ± 0.03, PAUC 0.65 ± 0.03, P<0.01). After adjustment of confounding factors, a high BPV remained a significant independent predictor of MACE (hazards ratio 1.67, 95% confidence interval 1.14-2.43, P<0.01). Compared with established surrogate markers of atherosclerosis, visit-to-visit BPV provides similar prognostic information and may represent a new and simple marker for adverse outcomes in patients with vascular diseases.

    Effects of oxygen-derived free radicals are suggested to be a potential pathogenic factor for endothelial dysfunction. In this study we sought to evaluate the effect of hydroxyl radicals on the human coronary vascular bed in type I diabetes mellitus using positron emission tomography (PET). Thirteen patients with type 1 diabetes underwent PET using nitrogen-13 ammonia at rest and during sympathetic stimulation with the cold pressor test (CPT). The rest-stress study protocol was repeated twice (on different days) using pre-stress infusion of either saline as placebo or deferoxamine, an iron chelator which inhibits generation of hydroxyl radicals. At rest, global MBF was higher in diabetics than in normal controls (78.1{+-}17.5 vs 63.2{+-}14.9 mg 100 g{sup -1} min{sup -1}, P<0.05) and myocardial vascular resistance (MVR) showed a trend towards lower values (patients, 1.28{+-}0.35; controls, 1.55{+-}0.32, P=NS). CPT increased MBF in all controls while 7/13 diabetics responded normally. CPT decreased MVR in 10/13 controls but in only 4/13 diabetics. There was no significant difference in the duration of diabetes, HbA1c, daily insulin dose, body mass index, or lipid profiles between patients with and patients without abnormal MBF or MVR responses. Pre-stress infusion of deferoxamine normalized MBF response in all six patients, and MVR response in six of the nine patients. Another group consisting of seven patients underwent a rest-rest protocol after infusion of deferoxamine and saline to investigate the effect of deferoxamine on resting MBF. Deferoxamine did not change the resting MBF (deferoxamine, 81{+-}17 ml 100 g{sup -1} min{sup -1}; saline, 75{+-}19 ml 100 g{sup -1} min{sup -1}, P=NS) or MVR (deferoxamine, 1.0{+-}0.5 mmHg ml{sup -1} 100 g{sup -1} min{sup -1}; saline, 1.2{+-}0.6 mmHg ml{sup -1} 100 g{sup -1} min{sup -1}, P=NS). In conclusion, inhibition of hydroxyl radical formation using deferoxamine significantly improved the responses of coronary

    To evaluate a pharmaceutical care protocol for patients with rheumatoid arthritis (RA) or psoriatic arthritis who begin treatment with etanercept with the objective of identifying potential medication-related problems and implementing therapeutic measures to improve the way this drug is used. An observational, prospective, 3-month study of patients with RA receiving etanercept therapy from March to December 2003 was conducted and a pharmaceutical care protocol was set up. During the first visit, a pharmacotherapeutic record was initiated for each patient, including socio-demographic data, personal history, diagnosis, DMARDs (disease-modifying anti-rheumatic drugs) previously received, and concomitant therapies for other underlying conditions. Patients were briefed on dosage, administration route, and potential adverse events both orally and in writing. Correct drug administration and preservation were verified during the second visit, where potential adverse effects were identified, treatment adherence was confirmed, and, if needed, potential drug interactions with other ongoing medications were disclosed. During the third visit, adherence was assessed, adverse events were recorded, and patients evaluated their response to treatment. Fifty patients were included, 40 with a diagnosis of rheumatoid arthritis (80%) and 10 diagnosed with psoriatic arthritis (20%). In all, 72% had received previous treatment with methotrexate (MTX), 40% with leflunomide, 20% with infliximab, 56% with corticoids, 2% with analgesics, 56% with NSAIDs, and 30% with other DMARDs. No significant drug interactions were found. Regarding adherence to treatment, 7.7% of patients skipped one or more doses, with travelling being the most common reason. Adverse events reported included: injection site reaction (27%), headache (7.7%) and nausea (7.7%). At 3 months after treatment onset, a reduction of MTX doses was seen in 18% of patients, of leflunomide dosage in 8%, of corticoids in 18%, of

    Objectives: To examine whether the inter-individual variation in constipation among patients receiving opioids for cancer pain is associated with genetic or non-genetic factors. Methods: Cancer patients receiving opioids were included from 17 centers in 11 European countries. Intensity of constipation was reported by 1,568 patients on a four-point categorical scale. Non-genetic factors were included as covariates in stratified regression analyses on the association between constipation and 75 single-nucleotide polymorphisms (SNPs) within 15 candidate genes related to opioid- or constipation-signaling pathways (HTR3E, HTR4, HTR2A, TPH1, ADRA2A, CHRM3, TACR1, CCKAR, KIT, ARRB2, GHRL, ABCB1, COMT, OPRM1, and OPRD1). Results: The non-genetic factors significantly associated with constipation were type of laxative, mobility and place of care among patients receiving laxatives (N=806), in addition to Karnofsky performance status and presence of metastases among patients not receiving laxatives (N=762) (P<0.01). Age, gender, body mass index, cancer diagnosis, time on opioids, opioid dose, and type of opioid did not contribute to the inter-individual differences in constipation. Five SNPs, rs1800532 in TPH1, rs1799971 in OPRM1, rs4437575 in ABCB1, rs10802789 in CHRM3, and rs2020917 in COMT were associated with constipation (P<0.01). Only rs2020917 in COMT passed the Benjamini–Hochberg criterion for a 10% false discovery rate. Conclusions: Type of laxative, mobility, hospitalization, Karnofsky performance status, presence of metastases, and five SNPs within TPH1, OPRM1, ABCB1, CHRM3, and COMT may contribute to the variability in constipation among cancer patients treated with opioids. Knowledge of these factors may help to develop new therapies and to identify patients needing a more individualized approach to treatment. PMID:26087058

    To compare the incidence of repeated red blood cell (RBC) transfusion in anemic gynecologic cancer patients receiving platinum-based chemotherapy comparing intravenous and oral iron. Forty-four anemic gynecologic cancer patients (hemoglobin level below 10 mg/dl) who required RBC transfusion were stratified and randomized according to baseline hemoglobin levels and chemotherapy regimen. Study group received 200 mg of intravenous iron sucrose and control group received oral ferrous sulphate 600 mg/day. RBC transfusion requirement in the consecutive cycle of chemotherapy was the primary outcome. Quality of life was evaluated by validated Thai version of the Functional Assessment of Cancer Therapy-Anemia (FACT-An). In a total of the 44 patients, there were 22 patients in each group. Five patients (22.7%) in the study group and 14 patients (63.6%) in the control group required RBC transfusion in consecutive cycle of chemotherapy (p=0.01). No significant difference in baseline hemoglobin and hematocrit levels was demonstrated in both groups. Significantly higher mean hemoglobin and hematocrit levels after treatment were reported in the study group (10.0+/-0.8 g/dl and 30.5+/-2.4%) than the control group (9.5+/-0.9 g/dl and 28.4+/-2.7%). No significant change of total FACT-An scores was noted between before and after treatment in both groups. No serious adverse events were reported and there was no significant difference among adverse events between both groups. Intravenous iron is an alternative treatment for anemic gynecologic cancer patients receiving platinum-based chemotherapy and reduces the incidence of RBC transfusion without serious adverse events.

    Patients with end-stage renal disease (ESRD) are clinically complex, requiring intensive and costly care. Coordinated care may improve outcomes and reduce costs. The objective of this study was to determine the impact of a payer-provider care partnership on key clinical and economic outcomes in enrolled patients with ESRD.  Retrospective observational study. Data on patient demographics and clinical outcomes were abstracted from the electronic health records of the dialysis provider. Data on healthcare costs were collected from payer claims. Data were collected for a baseline period prior to initiation of the partnership (July 2011-June 2012) and for two 12-month periods following initiation (April 2013-March 2014 and April 2014-March 2015). Among both Medicare Advantage and commercial insurance program members, the rate of central venous catheter use for vascular access was lower following initiation of the partnership compared with the baseline period. Likewise, hospital admission rates, emergency department visit rates, and readmission rates were lower following partnership initiation. Rates of influenza and pneumococcal vaccination were higher than 95% throughout all 3 time periods. Total medical costs were lower for both cohorts of members in the second 12-month period following partnership initiation compared with the baseline period. Promising trends were observed among members participating in this payer-provider care partnership with respect to both clinical and economic outcomes. This suggests that collaborations with shared incentives may be a valuable approach for patients with ESRD.

The use of dual (two maintenance treatments and triple (combination of any three treatments therapy has shown efficacy for symptom relief; however, some patients with COPD remain symptomatic despite these therapies. This study assessed the scope and magnitude of the symptomatic burden for patients with COPD receiving dual or triple therapy. Patients and methods: Cross-sectional data from three Adelphi COPD surveys (2013–2016 conducted in the USA, Europe, Japan, and China were analyzed for patients with COPD and forced expiratory volume in 1 second ≤65% receiving dual or triple therapy for ≥3 months. Physicians completed clinical and disease characteristic forms for identified patients. Corresponding patients completed questionnaires that included validated survey instruments to assess adherence and symptom impact. Descriptive statistics are reported. Results: Our analysis included 690 patients (mean age 68.2 years; 73.3% male; 41.4% and 58.6% were receiving dual and triple therapy, respectively. Most patients had dyspnea with substantial disability (modified Medical Research Council dyspnea scale rating ≥2, 56.3%; large health status impairment from symptoms, COPD Assessment Test score >20, 64.4%. A large symptom burden was observed, even for patients highly adherent to treatment (Morisky Medication Adherence Scale 8, 30.3% [185/612], of whom 62.1% still had a COPD Assessment Test score >20. Sensitivity analyses of patients regardless of their forced expiratory volume in 1 second status and of those receiving treatment for >6 months both reported similar results

    To evaluate the prognostic value of coronary atherosclerotic burden, assessed by coronary artery calcium (CAC) score, and coronary vascular function, assessed by coronary flow reserve (CFR) in patients with suspected coronary artery disease (CAD). We studied 436 patients undergoing hybrid {sup 82}Rb positron emission tomography/computed tomography imaging. CAC score was measured according to the Agatston method, and patients were categorized into three groups (0, <400, and ≥400). CFR was calculated as the ratio of hyperemic to baseline myocardial blood flow, and it was considered reduced when <2. Follow-up was 94% complete during a mean period of 47±15 months. During follow-up, 17 events occurred (4% cumulative event rate). Event-free survival decreased with worsening of CAC score category (p < 0.001) and in patients with reduced CFR (p < 0.005). At multivariable analysis, CAC score ≥400 (p < 0.01) and CFR (p < 0.005) were independent predictors of events. Including CFR in the prognostic model, continuous net reclassification improvement was 0.51 (0.14 in patients with events and 0.37 in those without). At classification and regression tree analysis, the initial split was on CAC score. For patients with a CAC score < 400, no further split was performed, while patients with a CAC score ≥400 were further stratified by CFR values. Decision curve analyses indicate that the model including CFR resulted in a higher net benefit across a wide range of decision threshold probabilities. In patients with suspected CAD, CFR provides significant incremental risk stratification over established cardiac risk factors and CAC score for prediction of adverse cardiac events. (orig.)

    The study was dedicated to investigating the change in information processing in brain networks of vascular dementia (VaD) patients during the process of decision making. EEG was recorded from 18 VaD patients and 19 healthy controls when subjects were performing a visual oddball task. The whole task was divided into several stages by using global field power analysis. In the stage related to the decision-making process, graph theoretical analysis was applied to the binary directed network derived from EEG signals at nine electrodes in the frontal, central, and parietal regions in δ (0.5-3.5Hz), θ (4-7Hz), α1 (8-10Hz), α2 (11-13Hz), and β (14-30Hz) frequency bands based on directed transfer function. A weakened outgoing information flow, a decrease in out-degree, and an increase in in-degree were found in the parietal region in VaD patients, compared to healthy controls. In VaD patients, the parietal region may also lose its hub status in brain networks. In addition, the clustering coefficient was significantly lower in VaD patients. Impairment might be present in the parietal region or its connections with other regions, and it may serve as one of the causes for cognitive decline in VaD patients. The brain networks of VaD patients were significantly altered toward random networks. The present study extended our understanding of VaD from the perspective of brain functional networks, and it provided possible interpretations for cognitive deficits in VaD patients.

    There were many reports about the "do not resuscitate" (DNR) order while practicing in the critical care units and conducting hospice affairs but limited in the neurological issues. This study investigated the possible flaws in the execution of the DNR order among patients who received acute neurological care in Taiwan. Over a 3-year period, we retrospectively reviewed the medical records of 77 deceased patients with neurological conditions for DNR orders. Registry and analysis works included demography, hospital courses, DNR data, and clinical usefulness of the lab and image examinations. Sixty-seven DNR orders were requested by the patients' families, and more than half were signed by the patients' children or grandchildren. The main DNR items were chest compression, cardiac defibrillation, and pacemaker use, although several DNR patients received resuscitation. The mean duration from the coding date to death was 7.6 days. Two-thirds of the patients with DNR requests remained in the intensive care unit, with a mean stay of 6.9 days. Several patients underwent regular roentgenography and blood tests on the day of their death, despite their DNR orders. Hospital courses and DNR items may be valuable information on dealing with the patients with DNR orders. The results of this study also suggest the public education about the DNR orders implemented for neurological illnesses.

    Pneumonia which develops in patients while living in their own home is categorized as community-acquired pneumonia (CAP), even if these patients are bedridden and receiving home health care. However, because of the differences in patient backgrounds, we speculated that the clinical outcomes and pathogens of bedridden patients with pneumonia who are receiving home health care would be different from those of CAP. We conducted a prospective study of patients with CAP who were hospitalized at our hospital from April 2007 through September 2009. We compared home health care bedridden pneumonia (performance status 4, PS4-CAP) with non-PS4-CAP in a total of 505 enrolled patients in this study. Among these, 66 had PS4-CAP, mostly associated with aspiration. Severity scores, mortality rate, recurrence rate and length of hospital stay of those with PS4-CAP were significantly higher than those with non-PS4-CAP. Drug resistant pathogens were more frequently isolated from patients with PS4-CAP than from those of non-PS4-CAP. The results of patients with PS4-CAP were in agreement with those of previous health care-associated pneumonia (HCAP) reports. The present study suggested home health care bedridden pneumonia should be categorized as HCAP, not CAP.

    The disparity between patients awaiting transplantation and available organs forced many patients to go overseas to receive a transplant. Few data concerning overseas transplantation in Korea are available and the Korea Society for Transplantation conducted a survey to evaluate the trend and outcome of overseas transplantation. The survey, conducted on June 2006, included 25 hospitals nationwide that followed up patients after receiving kidney transplant (KT) or liver transplant (LT) overseas. The number of KT increased from 6 in 2001 to 206 in 2005 and for LT from 1 to 261. The information about overseas transplant came mostly from other patients (57%). The mean cost for KT was $21,000 and for LT $47,000. Patients were admitted for 18.5 days for KT and 43.4 days for LT. Graft and patient survival was 96.8% and 96.5% for KT (median follow up 23.1 months). Complication occurred in 42.5% including surgical complication (5.3%), acute rejection (9.7%) and infection (21.5%). Patient survival for LT was 91.8% (median follow up 21.2 months). Complication occurred in 44.7% including 19.4% biliary complication. Overseas KT and LT increased rapidly from 2001 to 2005. Survival of patients and grafts was comparable to domestic organ transplantation, but had a high complication rate.

    The aim of the present study was to compare clinical features of patients with elevated serum digoxin concentrations who were treated with digoxin-Fab with those where the immunotherapy was not given by a tertiary hospital toxicology service. This was a retrospective series of patients with supratherapeutic serum digoxin concentrations referred to the toxicology service from August 2013 to October 2015. Data collected included demographics, presenting complaint, digoxin dose, other medications taken, serum digoxin, potassium and creatinine concentration on presentation and initial and post-digoxin-Fab heart rate. There were 47 referrals. Digoxin-Fab was administered in 21 cases. It was given more commonly when the heart rate was 5.0 mmol/L. Patients receiving digoxin-Fab were more likely to be on maintenance therapy with beta-blockers or calcium channel blockers (95% vs 61%; OR 13.1; 95% CI 1.5-113) and/or potassium-sparing medications (95% vs 54%; OR 17.1; 95% CI 2.0-147). They had elevated serum creatinine (76% vs 42%; OR 8.2; 95% CI 1.9-34), higher serum potassium (median: 5.1 mmol/L vs 4.2 mmol/L, P = 0.02), higher serum digoxin concentration (median: 3.5 nmol/L vs 2.3 nmol/L, P = 0.02) and pretreatment heart rate Fab. However, individual heart rate response to digoxin-Fab was variable. Digoxin-Fab was more commonly administered when heart rate was Fab was variable as patients were using other negative chronotropic medications. In symptomatic bradycardic patients on multiple heart failure medications, positive chronotropic and potassium-lowering therapies should be considered in concert with digoxin-Fab. © 2018 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    to verify the nursing diagnoses in patients affected by CVAs. this is an integrative review of the literature. The search was conducted on LILACS, Scielo, Medline, CINAHL, and Scopus databases between February and March 2015, using the following keywords: "Enfermagem", "Acidente Vascular Cerebral", "Diagnóstico de Enfermagem"; and "Nursing", "Stroke", and "Nursing Diagnosis". we found 9 articles published between 2009 and 2015; most of them were Brazilian, cross-sectional, and exploratory, with a level of evidence of 6. The evidence from the publications was classified as: "Evaluation and validation of specific nursing diagnoses for subjects affected by CVAs" and "Application of the nursing process on subjects affected by CVAs". we noticed the publications focused on nursing diagnoses related to motor disorders, such as risk of falls and impaired physical mobility. Domains regarding safety/protection (domain 11) and sleep/resting (domain 4) were present in most evaluated publications.

    Acute ischemic brain injury (stroke, stroke), a leader among the causes of morbidity and mortality in the world. This pathology is one of the most pressing health and social problems that cause enormous economic damage to society, due to the high fatality rate, significant disability and social maladjustment of patients, which is based in most cases are the motor and cognitive impairment. Despite the fact that, currently established risk factors and pathophysiological basis of this disease, the availability of effective methods of diagnosing illness, still a practicing neurologist in some cases difficult to find adequate therapy that could effectively reach a well-established neurological deficit. Therefore the search for treatments that effectively reduce the health and social consequences of vascular damage to the brain, is one of the priority areas of neurology.

    After the Fontan operation, patients are at a substantial risk of the development of impaired functional health status. Few early markers of suboptimal outcomes have been identified. We sought to assess the association between peripheral vascular function and functional health status in Fontan-palliated patients. Asymptomatic Fontan patients (n = 51) and age- and gender-matched healthy controls (n = 22) underwent endothelial pulse amplitude testing using a noninvasive fingertip peripheral arterial tonometry (PAT) device. Raw data were transformed into the PAT ratio, an established marker of vascular function. Cardiopulmonary exercise testing was performed using the Bruce protocol. In the Fontan cohort, 94% of patients were New York Heart Association functional class I and 88% had a B-type natriuretic peptide level of interquartile range 1.96 to 4.13 vs median 1.86, interquartile range 1.14 to 2.79, p = 0.03). The PAT ratio, a measure of reactive hyperemia, was lower in Fontan patients (median 0.17, interquartile range -0.04 to 0.44, vs median 0.50, interquartile range 0.27 to 0.74, p = 0.002). The key parameters of exercise performance, including peak oxygen consumption (median 28.8 ml/kg/min, interquartile range 25.6 to 33.2 vs median 45.5 ml/kg/min, interquartile range 41.7 to 49.9, p interquartile range 150 to 246 vs median 330, interquartile range 209 to 402 W, p <0.0001), were lower in Fontan patients than in the controls. The PAT ratio correlated with the peak oxygen consumption (r = 0.28, p = 0.02) and peak work (r = 0.26, p = 0.03). In conclusion, in an asymptomatic Fontan population, there is evidence of reduced basal peripheral arterial tone and vasodilator response, suggesting dysfunction of the endothelium-derived nitric oxide pathway. Vasodilator function appears to correlate with exercise performance. Copyright © 2011 Elsevier Inc. All rights reserved.

Retrospective analysis of 49 consecutive patients. Multidisciplinary ventilatory rehabilitation unit in an academic medical center. Forty-nine consecutive chronic ventilator-dependent patients referred to a tertiary care hospital ventilator rehabilitation unit. None. Patients were 58 +/- 7 yrs old with multiple etiologies for respiratory failure. On admission, all patients were bedridden and had severe weakness of upper and lower extremities measured by a 5-point muscle strength score and a 7-point Functional Independence Measurement. Postrehabilitation, patients had increases in upper and lower extremity strength (p respiratory muscle training with an improvement in strength, weaning outcome, and functional status. Whole-body rehabilitation should be considered a significant component of their therapy.

    Evidence suggests that some aspects of schizophrenia can be induced in healthy volunteers through acute administration of the non-competitive NMDA-receptor antagonist, ketamine. In probabilistic inference tasks, patients with schizophrenia have been shown to ‘jump to conclusions’ (JTC) when asked to make a decision. We aimed to test whether healthy participants receiving ketamine would adopt a JTC response pattern resembling that of patients. The paradigmatic task used to investigate JTC has been the ‘urn’ task, where participants are shown a sequence of beads drawn from one of two ‘urns’, each containing coloured beads in different proportions. Participants make a decision when they think they know the urn from which beads are being drawn. We compared performance on the urn task between controls receiving acute ketamine or placebo with that of patients with schizophrenia and another group of controls matched to the patient group. Patients were shown to exhibit a JTC response pattern relative to their matched controls, whereas JTC was not evident in controls receiving ketamine relative to placebo. Ketamine does not appear to promote JTC in healthy controls, suggesting that ketamine does not affect probabilistic inferences. PMID:22389244

    The Internet is frequently accessed by patients as a resource for medical knowledge. However, the provided material is typically written at a level well above the recommended 7th grade level. A clear understanding of the capabilities, limitations, risks, and benefits of interventional radiology by patients, both current and prospective, is hindered when the textual information offered to the public is pitched at a level of sophistication too high for general comprehension. In January 2013, all 25 patient education resources from the Cardiovascular and Interventional Radiology Society of Europe (CIRSE) Web site ( http://www.cirse.org ) and all 31 resources from the Society of Interventional Radiology (SIR) Web site ( http://www.sirweb.org ) were analyzed for their specific level of readability using ten quantitative scales: Flesch Reading Ease, Flesch-Kincaid Grade Level, Simple Measure of Gobbledygook, Gunning fog index, New Fog Count, Coleman-Liau index, FORCAST formula, Fry graph, Raygor Readability Estimate, and New Dale-Chall. Collectively, the patient education resources on the CIRSE Web site are written at the 12.3 grade level, while the resources on the SIR Web site are written at the 14.5 grade level. Educational health care materials available on both the CIRSE and the SIR Web sites are presented in language in the aggregate that could be too difficult for many lay people to fully understand. Given the complex nature of vascular and interventional radiology, it may be advantageous to rewrite these educational resources at a lower reading level to increase comprehension.

    The fasting plasma levels of nine gastrointestinal regulatory peptides were measured by radioimmunoassay in 13 stable patients with chronic renal failure, receiving hemodialysis treatment regularly and compared with those of ten healthy controls. The plasma concentrations of gastrin-releasing peptide, motilin, neurotensin, pancreatic polypeptide, peptide YY, somatostatin, substance P, and vasoactive intestinal peptide were increased. The plasma level of gastrin was not statistically different from that of the control (p=0.077). It is concluded that patients with chronic renal failure, receiving hemodialysis treatment regularly, have increased concentrations of eight of nine measured gastrointestinal regulatory peptides. The elevated levels of gastrointestinal peptides in patients with chronic renal failure may contribute to uremic gastrointestinal symptoms and dysfunctions. It is necessary to make a renal function evaluation before interpreting measured plasma levels of gastrointestinal regulatory peptides. 62 refs., 2 tabs

    Although red wine (RW) reduces cardiovascular risk, the mechanisms underlying the effect have not been identified. Correction of endothelial dysfunction by RW flavonoids could be one mechanism. We measured brachial artery reactivity by high-resolution ultrasonography, plasma lipids, glucose, adhesion molecules (ICAM-1 and VCAM), and platelet function in 16 hypercholesterolemic individuals (8 men and 8 women; mean age 51.6 +/- 8.1 years) without other risk factors. Twenty-four normal subjects were used as controls for vascular reactivity. Subjects randomly received RW, 250 ml/day, or purple grape juice (GJ), 500 ml/day, for 14 days with an equal wash-out period. At baseline, all 16 subjects were hypercholesterolemic (mean LDL = 181.0 +/- 28.7 mg/dl) but HDL, triglycerides, glucose, adhesion molecules, and platelet function were within normal limits. Brachial artery flow-mediated dilation was significantly decreased compared to controls (9.0 +/- 7.1 vs 12.1 +/- 4.5%; P effect on either molecule. No significant alterations were observed in plasma lipids, glucose or platelet aggregability with RW or GJ. Both RW and GJ similarly improved flow-mediated dilation, but RW also enhanced endothelium-independent vasodilation in hypercholesterolemic patients despite the increased plasma cholesterol. Thus, we conclude that GJ may protect against coronary artery disease without the additional negative effects of alcohol despite the gender.

    The purpose of this retrospective review was to evaluate concordance with evidence-based quality indicator guidelines for prostate cancer patients treated radically in a 'generalist' (as distinct from 'sub-specialist') centre. We were concerned that the quality of treatment may be lower in a generalist centre. If so, the findings could have relevance for many radiotherapy departments that treat prostate cancer. Two hundred fifteen consecutive patients received external beam radiotherapy (EBRT) and/or brachytherapy between 1.10.11 and 30.9.12. Treatment was deemed to be in line with evidence-based guidelines if the dose was: (i) 73.8-81 Gy at 1.8-2.0 Gy/fraction for EBRT alone (eviQ guidelines); (ii) 40-50 Gy (EBRT) for EBRT plus high-dose rate (HDR) brachytherapy boost (National Comprehensive Cancer Network (NCCN) guidelines); and (iii) 145 Gy for low dose rate (LDR) I-125 monotherapy (NCCN). Additionally, EBRT beam energy should be ≥6 MV using three-dimensional conformal RT (3D-CRT) or intensity-modulated RT (IMRT), and high-risk patients should receive neo-adjuvant androgen-deprivation therapy (ADT) (eviQ/NCCN). Treatment of pelvic nodes was also assessed. One hundred four high-risk, 84 intermediate-risk and 27 low-risk patients (NCCN criteria) were managed by eight of nine radiation oncologists. Concordance with guideline doses was confirmed in: (i) 125 of 136 patients (92%) treated with EBRT alone; (ii) 32 of 34 patients (94%) treated with EBRT + HDR BRT boost; and (iii) 45 of 45 patients (100%) treated with LDR BRT alone. All EBRT patients were treated with ≥6 MV beams using 3D-CRT (78%) or IMRT (22%). 84%, 21% and 0% of high-risk, intermediate-risk and low-risk patients received ADT, respectively. Overall treatment modality choice (including ADT use and duration where assessable) was concordant with guidelines for 176/207 (85%) of patients. The vast majority of patients were treated concordant with evidence-based guidelines suggesting that

    Shared decision-making (SDM) has been advocated as the preferred method of choosing a suitable treatment option. However, patient involvement in treatment decision-making is not yet common practice in the field of vascular surgery. The aim of this mixed-methods study was to explore patients' decision-making preferences and to investigate which facilitators and barriers patients perceive as important for the application of SDM in vascular surgery. Patients were invited to participate after visiting the vascular surgical outpatient clinic of an Academic Medical Center in the Netherlands. A treatment decision was made during the consultation for an abdominal aortic aneurysm or peripheral arterial occlusive disease. Patients filled in a number of questionnaires (quantitative part) and a random subgroup of patients participated in an in-depth interview (qualitative part). A total of 67 patients participated in this study. 58 per cent of them (n=39) indicated that they preferred a shared role in decision-making. In more than half of the patients (55%; n=37) their preferred role was in disagreement with what they had experienced. 31 per cent of the patients (n=21) preferred a more active role in the decision-making process than they had experienced. Patients indicated a good patient-doctor relationship as an important facilitator for the application of SDM. The vast majority of vascular surgical patients preferred, but did not experience a shared role in the decision-making process, although the concept of SDM was insufficiently clear to some patients. This emphasises the importance of explaining the concept of SDM and implementing it in the clinical encounter. Published by the BMJ Publishing Group Limited.

    Purpose: We previously reported the advantages of 18 F-fluorodeoxyglucose-positron emission tomography (PET) fused with CT for radiotherapy planning over CT alone in head and neck carcinoma (HNC). The purpose of this study was to evaluate clinical outcomes and the predictive value of PET for patients receiving PET/CT-guided definitive radiotherapy with or without chemotherapy. Methods and Materials: From December 2002 to August 2006, 42 patients received PET/CT imaging as part of staging and radiotherapy planning. Clinical outcomes including locoregional recurrence, distant metastasis, death, and treatment-related toxicities were collected retrospectively and analyzed for disease-free and overall survival and cumulative incidence of recurrence. Results: Median follow-up from initiation of treatment was 32 months. Overall survival and disease-free survival were 82.8% and 71.0%, respectively, at 2 years, and 74.1% and 66.9% at 3 years. Of the 42 patients, seven recurrences were identified (three LR, one DM, three both LR and DM). Mean time to recurrence was 9.4 months. Cumulative risk of recurrence was 18.7%. The maximum standard uptake volume (SUV) of primary tumor, adenopathy, or both on PET did not correlate with recurrence, with mean values of 12.0 for treatment failures vs. 11.7 for all patients. Toxicities identified in those patients receiving intensity modulated radiation therapy were also evaluated. Conclusions: A high level of disease control combined with favorable toxicity profiles was achieved in a cohort of HNC patients receiving PET/CT fusion guided radiotherapy plus/minus chemotherapy. Maximum SUV of primary tumor and/or adenopathy was not predictive of risk of disease recurrence

    Objective: To evaluate batroxobin in preventing vascular restenosis in diabetic patients after infrapopliteal arterial angioplasty through comparing the clinical results of the combination use of batroxobin and aspirin with that of simple use of aspirin. Methods: After a successful angioplasty, fifty-two diabetic patients with symptomatic infrapopliteal obstructions were randomly divided into the study group (n=26) and the control group (n=26). Patients in both groups received 100 aspirin everyday, but the patients in study group additionally received 5 IU batroxobin intravenous drip every day for six times. At the end of the follow-up period lasting for 12 months, magnetic resonance angiography (MRA) or Doppler ultrasonic angiography was performed to check the vessels to see if there was any restenosis or reocclusion. The relief degree of clinical symptoms were observed, and both preoperative and postoperative ankle-brachial index (ABI) were regularly determined and compared. Kaplan-Meier curves were constructed to evaluate restenosis/reocclusion-free rate, limb salvage rate and amputation-free rate. Results: During the follow-up period the occurrence of restenosis/reocclusion in study group and control group was 22.0% and 34.5% respectively (P=0.0307). Statistically significant difference in ABI existed between two groups both after the procedure (P<0.05) and at 12 months after the treatment (P=0.0094). Clinical improvement and tissue healing in study group and control group were observed in 23 and 19 patients respectively (P=0.0544). Twelve months after angioplasty, Kaplan-Meier analysis showed that the restenosis/reocclusion-free rate, the limb salvage rate and the amputation-free rate for study group were 74.0%, 96.2% and 84.6% respectively, while they was 54.8%, 92.3% and 84.6% respectively for control group. Conclusion: The results of this study indicate that the use of the clinical therapeutic efficacy and markedly relieve the symptoms, although this

    Growing methadone use in pain management has raised concerns regarding its safety relative to other long-acting opioids. Methadone hydrochloride may increase the risk for lethal respiratory depression related to accidental overdose and life-threatening ventricular arrhythmias. To compare the risk of out-of-hospital death in patients receiving methadone for noncancer pain with that in comparable patients receiving sustained-release (SR) morphine sulfate. A retrospective cohort study was conducted using Tennessee Medicaid records from 1997 through 2009. The cohort included patients receiving morphine SR or methadone who were aged 30 to 74 years, did not have cancer or another life-threatening illness, and were not in a hospital or nursing home. At cohort entry, 32 742 and 6014 patients had filled a prescription for morphine SR or methadone, respectively. The patients' median age was 48 years, 57.9% were female, and comparable proportions had received cardiovascular, psychotropic, and other musculoskeletal medications. Nearly 90% of the patients received the opioid for back pain or other musculoskeletal pain. The median doses prescribed for morphine SR and methadone were 90 mg/d and 40 mg/d, respectively. The primary study end point was out-of-hospital mortality, given that opioid-related deaths typically occur outside the hospital. There were 477 deaths during 28 699 person-years of follow-up (ie, 166 deaths per 10 000 person-years). After control for study covariates, patients receiving methadone had a 46% increased risk of death during the follow-up period, with an adjusted hazard ratio (HR) of 1.46 (95% CI, 1.17-1.83; P Methadone doses of 20 mg/d or less, the lowest dose quartile, were associated with an increased risk of death (HR, 1.59; 95% CI, 1.01-2.51, P = .046) relative to a comparable dose of morphine SR (methadone in this retrospective cohort study, even for low doses, supports recommendations that it should not be a drug of first choice for

    Full Text Available The paper presents results of clinical application of autologous stromal-vascular fraction (SVF cells in patients with degenerative osteoarthritis (OA of the knee, grade II and III (Kellgren–Lawrence scale.We recruited six patients with knee OA (3 men and 3 women; median age 64 years with mean disease duration of 7 years. All the patients were administered a single intra-articular injection of autologous nucleated SVF cells at an average dose of 16.8±0.9 × 106 per joint (a total of 11 joints. The patients did not experience any serious side effects (allergic, toxic or inflammatory related to the knee injection. Patient surveys at 1 month after SVF administration revealed a decrease in the severity of pain, as measured by a visual analog scale (VAS and a specialized 100-point scale KOOS (subscale "pain" (p < 0.05 on both scales. Moreover, the patients reported improvement in the joint functions and quality of life related to affected joints on a KOOS scale (p < 0.05. These positive clinical changes persisted during 6 month follow up. Significant improvements were noted in ultrasound findings, with increased thickness of the cartilage layer at 3 months (in 73% of cases and at 6 months (in 82%. Our pilot study demonstrated the safety and tolerability of intra-articular injection of autologous SVF cells in patients with moderate to severe OA. The results obtained also indicate a significant antiinflammatory effect of autologous adipose tissue SVF cells, which is manifested at the early stages of cell therapy. Our further investigations will be focused on exploring the SVF stimulatory effects on regeneration of damaged joints.

    The aim of this study was to assess qualitatively the psychological stressors affecting patients with cutaneous vascular malformations and hemangiomas (CVM-H) and their impact on compliance to interventional treatment. A retrospective chart review was conducted of all patients with CVM-H treated by interventional neuroradiology at a single academic institution during a five-year period (2009-2014). Psychological complaints were documented during each clinic visit by a neuroradiologist. Compliance to interventional treatment was defined by adherence to the scheduled treatment sessions. Fisher's exact test was used to assess for associations between psychological complaints and compliance. Seventy-five patients were assessed, of whom 49 (65.3%) were female, with an age range of 2-78 years (mean age 30.2 years). All except one patient older than seven years of age (n = 71; 94.6%) had a psychological complaint, including fear of negative appearance (n = 53; 70.6%), dissatisfaction with appearance (n = 46; 61.3%), low self-esteem (n = 35; 46.6%), anxiety (n = 16; 21.3%), stress (n = 13; 17.3%), bullying (n = 5; 6.6%), and low mood (n = 4; 5.3%). Twenty-three (31%) patients were non-compliant. Low self-esteem was significantly associated with non-compliance (p = 0.0381). There is a high prevalence of psychological comorbidities among patients treated for CVM-H. This has potential implications for interventional treatment, as it was found that low self-esteem is significantly associated with non-compliance. These results suggest the need for early psychological support in these patients in order to maximize compliance to interventional treatment. © The Author(s) 2016.

    Sub-optimal nutrition status is common amongst patients receiving peritoneal dialysis (PD) and leads to poor clinical outcome. This population experiences multi-factorial challenges to achieving optimal nutritional status, particularly driven by inadequate intake. The aim of this investigation was to identify factors associated with inadequate protein intake and sub-optimal nutritional status in patients undergoing PD. This was a cross-sectional study of 67 adult patients receiving PD (mean age 59 ± 14 years; 57% male) within a single centre. Participants were consecutively recruited and interviewed by renal dietitians, collecting: Subjective Global Assessment (SGA); quality of life (using EQ-5D); dietary intake (via dietary interview); and appetite (using Appetite and Diet Assessment Tool). Participant demographics were obtained via survey or medical charts. Main outcome measures were inadequate dietary protein intake (anorexia) was reported in 62% (18/29) of participants with inadequate protein malnourished patients reported anorexia versus 12 (23%) of the well-nourished patients (p = 0.0001). Anorexia was a key risk factor for inadequate protein intake and malnutrition in patients undergoing PD. These findings highlight a need to closely monitor patients with appetite disturbances. © 2016 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    Published CRRT drug dosing algorithms and other dosing guidelines appear to result in underdosed antibiotics, leading to failure to attain pharmacodynamic targets. High mortality rates persist with inadequate antibiotic therapy as the most important risk factor for death. Reasons for unintended antibiotic underdosing in patients receiving CRRT are many. Underdosing may result from lack of the recognition that better hepatic function in AKI patients yields higher nonrenal antibiotic clearance compared to ESRD patients. Other factors include the variability in body size and fluid composition of patients, the serious consequence of delayed achievement of antibiotic pharmacodynamic targets in septic patients, potential subtherapeutic antibiotic concentrations at the infection site, and the influence of RRT intensity on antibiotic concentrations. Too often, clinicians weigh the benefits of overcautious antibiotic dosing to avoid antibiotic toxicity too heavily against the benefits of rapid attainment of therapeutic antibiotic concentrations in critically ill patients receiving CRRT. We urge clinicians to prescribe antibiotics aggressively for these vulnerable patients. © 2014 Wiley Periodicals, Inc.

    Sickle cell disease (SCD) is common in the Arabian Gulf region. Most cases require a red blood cell (RBC) transfusion, increasing the potential for RBC alloantibody development. The incidence of RBC alloimmunization among Kuwaiti Arab SCD patients is not yet known. This study retrospectively assessed the effect of using two different matching protocols on the incidence of alloimmunization among multiply transfused Kuwaiti Arab SCD patients. A total of 233 Kuwaiti Arab SCD patients were divided into two groups: Group 1 (n = 110) received RBC transfusion through standard ABO- and D-matched nonleukoreduced blood; Group 2 (n = 123) received RBCs matched for ABO, Rh, and K1 poststorage-leukoreduced blood. Multivariate analysis was performed on the factors associated with RBC alloimmunization and antibody specificity. Sixty-five percent of patients in Group 1 developed clinically significant RBC alloantibody with an increased prevalence in females; in patients in Group 2, 23.6% developed RBC alloantibodies (p = 0.01). In Group 1, 72 patients (65.5%) had alloantibodies directed against Rh and Kell systems (p = 0.01). Multivariate analysis further confirmed the results, showing that blood transfusion type and sex have significant effects on the rate of alloimmunizations. This study confirms the importance of selecting RBCs matched for Rh and Kell to reduce the risk of alloimmunizations among Kuwaiti Arab SCD patients.

    To investigate the prognostic value of electrodiagnostic testing in patients with sciatica receiving physical therapy. Electrodiagnostic testing was performed on 38 patients with sciatica participating in a randomized trial comparing different physical therapy interventions. Patients were grouped and analyzed according to the presence or absence of radiculopathy based on electrodiagnostic testing. Longitudinal data analysis was conducted using multilevel growth modeling with ten waves of data collected from baseline through the treatment and post-treatment periods up to 6 months. The primary outcome measure was changes in low back pain-related disability assessed using the Roland and Morris disability questionnaire (RMDQ). Patients with radiculopathy (n = 19) had statistically significant and clinically meaningful improvements in RMDQ scores at every post-treatment follow-up occasion regardless of treatment received. The final multilevel growth model revealed improvements in RMDQ scores in patients with radiculopathy at the 6-week (-8.1, 95 % CI -12.6 to -2.6; P = 0.006) and 6-month (-4.1, 95 % CI -7.4 to -0.7; P = 0.020) follow-up occasions compared to patients without radiculopathy. Treatment group was not a significant predictive factor at any follow-up occasion. An interaction between electrodiagnostic status and time revealed faster weekly improvements in RMDQ scores in patients with radiculopathy at the 6-week (-0.72, 95 % CI -1.4 to -0.04; P = 0.040) through the 16-week (-0.30, 95 % CI, -0.57 to -0.04; P = 0.028) follow-up occasions compared to patients without radiculopathy. The presence of lumbosacral radiculopathy identified with electrodiagnostic testing is a favorable prognostic factor for recovery in low back pain-related disability regardless of physical therapy treatment received.

    Objective: To determine the immune abnormalities and occurrence of infections in transfusion-dependent -thalassemia major patients receiving oral iron chelator deferasirox (DFX). Study Design: An observational study. Place and Duration of Study: Hematology Clinics, King Khalid University Hospital, Riyadh, Saudi Arabia, from July to December 2010. Methodology: Seventeen patients with -thalassemia major (12 females, median age 26 years) receiving deferasirox (DFX) for a median duration of 27 months were observed for any infections and had their immune status determined. Immune parameters studied included serum immunoglobulins and IgG subclasses, serum complement (C3 and C4) and anti-nuclear antibody (ANA) level, total B and T-lymphocytes, CD4+ and CD8+ counts, CD4+/CD8+ ratio, and natural killer (NK) cells. Immunological parameters of the patients were compared with age, gender, serum ferritin level and splenectomy status. Lymphocyte subsets were also compared with age and gender matched normal controls. Results: A considerable reduction in serum ferritin was achieved by DFX from a median level of 2528 to 1875 mol/l. Serum IgG levels were increased in 7 patients. Low C4 levels were found in 9 patients. Total B and T-lymphocytes were increased in 14 patients each, while CD4+, CD8+ and NK cells were increased in 13, 12 and 11 patients respectively. Absolute counts for all lymphocyte subsets were significantly higher compared to the normal controls (p=0.05 for all parameters). Raised levels of IgG were associated with older age, female gender, splenectomized status and higher serum ferritin levels but this did not reach statistical significance except for the higher ferritin levels (p=0.044). Increased tendency to infections was not observed. Conclusion: Patients with -thalassemia major receiving DFX exhibited significant immune abnormalities. Changes observed have been described previously, but could be related to DFX. The immune abnormalities were not associated with

    Full Text Available Background: Considering the incidence and prevalence rates of gastric cancer in Mazandaran Province of Iran, this research was performed to evaluate the efficacy and safety of olanzapine in symptom relief and quality of life (QOL improvement of gastric patients receiving chemotherapy. Materials and Methods: This clinical trial was conducted on thirty new cases of gastric cancer patients whose treatment protocol was planned on chemotherapy and were allocated into two groups by simple random sampling. Intervention group (15 patients received olanzapine tablets (2.5–10 mg/day a day before the beginning of chemotherapy; in the 1st day of chemotherapy to 8 weeks after chemotherapy, besides the routine treatment regimens. The control group received only the routine treatment regimens. The patients were followed for 8 weeks after intervention. All of the patients were assessed with Hospital Anxiety and Depression Scale (HADS and WHO-QOL-BREF questionnaires; further, Rhodes index was used to evaluate nausea and vomiting (N/V status. Results: All the recruited patients continued the allocated interventions (no lost to follow-up. N/V decreased in the case group, but the difference was not statistically significant (P = 0.438. The patients' appetite and body mass index increased (P = 0.006. Anxiety and depression subscales of HADS had significant differences between the two groups (P 0.05. No significant increase was observed in fasting and 2-h postprandial blood glucose and lipid profile (P > 0.05. Conclusion: Olanzapine can be considered as an effective drug to increase appetite and decrease anxiety and depression in patients with gastric cancer.

    We investigated the trace element status in Crohn's disease (CD) patients receiving enteral nutrition, and evaluated the effects of trace element-rich supplementation. Thirty-one patients with CD were enrolled in this study. All patients were placed on an enteral nutrition regimen with Elental(R) (Ajinomoto pharmaceutical. Ltd., Tokyo, Japan). Serum selenium, zinc and copper concentrations were determined by atomic absorption spectroscopy. Serum selenoprotein P levels were determined by an ELISA system. Average serum levels of albumin, selenium, zinc and copper were 4.1 +/- 0.4 g/dl, 11.2 +/- 2.8 microg/dl, 71.0 +/- 14.8 microg/dl, and 112.0 +/- 25.6 microg/dl, respectively. In 9 patients of 31 CD patients, serum albumin levels were lower than the lower limit of the normal range. Serum selenium, zinc and copper levels were lower than lower limits in 12 patients, 9 patients and 1 patient, respectively. Serum selenium levels significantly correlated with both serum selenoprotein P levels and glutathione peroxidase activity. Supplementation of selenium (100 microg/day) and zinc (10 mg/day) for 2 months significantly improved the trace element status in CD patients. In conclusion, serum selenium and zinc levels are lower in many CD patients on long-term enteral nutrition. In these patients, supplementation of selenium and zinc was effective in improving the trace element status.

    Inflammatory Bowel Disease (IBD) patients with anxiety and/or depressive symptoms may not receive the care they need. Provision of care requires insight into the factors affecting these psychiatric symptoms. The study was designed to examine the extent to which: (1) IBD patients with anxiety and/or depressive symptoms receive mental treatment and (2) clinical and socio-demographic variables are associated with these symptoms. 231 adult IBD patients (79% response rate), attending a tertiary care center, completed standardized measures on anxiety and depressive symptoms (HADS), quality of life (SF-12) and mental health care use (TIC-P). Diagnosis and disease activity were determined by the gastroenterologist. 43% had high levels of anxiety and/or depressive symptoms, indicative of a psychiatric disorder (HADS ≥ 8), of whom 18% received psychological treatment and 21% used psychotropic medication. In multivariate analysis, high disease activity was associated with anxiety (OR=2.72 | psymptoms and poor quality of life, psychiatric complaints in IBD patients were undertreated. Screening for and treatment of psychiatric symptoms should become an integral part of IBD medical care. Copyright © 2011 European Crohn's and Colitis Organisation. Published by Elsevier B.V.

    Because a limited number of patients receive heart transplantation, alternative therapies, such as left ventricular assist device (LVAD) therapy, have emerged. Published studies have shown that LVAD implantation, by itself, improves exercise tolerance to the point where it is comparable to those with mild heart failure. The improvement in exercise capacity is maximally achieved 12 weeks after LVAD therapy and can continue even after explantation of the device. This effect varies, depending on the type of LVAD and exercise training. The available data in the literature on safety and benefits of exercise training in patients after LVAD implantation are limited, but the data that are available suggest that training trends to be safe and have an impact on exercise capacity in LVAD patients. Although no studies were identified on the role of cardiac rehabilitation programs in the management of LVAD patients, it appears that cardiac rehabilitation programs offer an ideal setting for the provision of supervised exercise training in this patient group.

    While electroconvulsive therapy (ECT) has been used for many years, there is insufficient research regarding the indications for continuation/maintenance (C/M)-ECT, its safety and efficacy, and the characteristics of patients with schizophrenia or schizoaffective disorder who receive multiple ECT sessions. The aims of this study were to characterize a series of patients who received 30 ECT sessions or more, to describe treatment regimens in actual practice, and to examine the results of C/M-ECT in terms of safety and efficacy, especially the effect on aggression and functioning. We performed a retrospective chart review of 20 consecutive patients (mean age 64.6 years) with schizophrenia (n=16) or schizoaffective disorder (n=4) who received at least 30 ECT sessions at our ECT unit, and also interviewed the treating physician and filled out the Clinical Global Impression-Severity, Global Assessment of Functioning, and the Staff Observation Aggression Scale-Revised. Patients received a mean of 91.3 ECT sessions at a mean interval of 2.6 weeks. All had been hospitalized for most or all of the previous 3 years. There were no major adverse effects, and cognitive side effects were relatively minimal (cognitive deficit present for several hours after treatment). We found that ECT significantly reduced scores on the Staff Observation Aggression Scale-Revised subscales for verbal aggression and self-harm, and improved Global Assessment of Functioning scores. There were reductions in total aggression scores, subscale scores for harm to objects and to others, and Clinical Global Impression-Severity scores, these were not statistically significant. C/M-ECT is safe and effective for chronically hospitalized patients. It improves general functioning and reduces verbal aggression and self-harm. More research using other aggression tools is needed to determine its effects and to reproduce our findings in prospective and controlled studies.

    Full Text Available The first non-vitamin K antagonist oral anticoagulant (NOAC introduced to the market in Japan was dabigatran in March 2011, and three more NOACs, rivaroxaban, apixaban, and edoxaban, have since become available. Randomized controlled trials of NOACs have revealed that intracranial hemorrhage (ICH occurs less frequently with NOACs compared with warfarin. However, the absolute incidence of ICH associated with NOACs has increased with greater use of these anticoagulants, and we wanted to explore the incidence, clinical characteristics, and treatment course of patients with NOACs-associated ICH.We retrospectively analyzed the characteristics of symptomatic ICH patients receiving NOACs between March 2011 and September 2014.ICH occurred in 6 patients (5 men, 1 woman; mean ± SD age, 72.8 ± 3.2 years. Mean time to onset was 146.2 ± 111.5 days after starting NOACs. Five patients received rivaroxaban and 1 patient received apixaban. None received dabigatran or edoxaban. Notably, no hematoma expansion was observed within 24 h of onset in the absence of infusion of fresh frozen plasma, activated prothrombin complex concentrate, recombinant activated factor VIIa or hemodialysis. When NOAC therapy was initiated, mean HAS-BLED and PANWARDS scores were 1.5 ± 0.5 and 39.5 ± 7.7, respectively. Mean systolic blood pressure was 137.8 ± 15.9 mmHg within 1 month before spontaneous ICH onset.Six symptomatic ICHs occurred early in NOAC therapy but hematoma volume was small and did not expand in the absence of infusion of reversal agents or hemodialysis. The occurrence of ICH during NOAC therapy is possible even when there is acceptable mean systolic blood pressure control (137.8 ± 15.9 mmHg and HAS-BLED score ≤ 2. Even stricter blood pressure lowering and control within the acceptable range may be advisable to prevent ICH during NOAC therapy.

    Community acupuncture is a recent innovation in acupuncture service delivery in the U.S. that aims to improve access to care through low-cost treatments in group-based settings. Patients at community acupuncture clinics represent a broader socioeconomic spectrum and receive more frequent treatments compared to acupuncture users nationwide. As a relatively new model of acupuncture in the U.S., little is known about the experiences of patients at community acupuncture clinics and whether quality of care is compromised through this high-volume model. The aim of this study was to assess patients' perspectives on the care received through community acupuncture clinics. The investigators conducted qualitative, thematic analysis of written comments from an observational, cross-sectional survey of clients of the Working Class Acupuncture clinics in Portland, Oregon. The survey included an open-ended question for respondents to share comments about their experiences with community acupuncture. Comments were received from 265 community acupuncture patients. Qualitative analysis of written comments identified two primary themes that elucidate patients' perspectives on quality of care: 1) aspects of health care delivery unique to community acupuncture, and 2) patient engagement in health care. Patients identified unique aspects of community acupuncture, including structures that facilitate access, processes that make treatments more comfortable and effective and holistic outcomes including physical improvements, enhanced quality of life, and empowerment. The group setting, community-based locations, and low cost were highlighted as aspects of this model that allow patients to access acupuncture. Patients' perspectives on the values and experiences unique to community acupuncture offer insights on the quality of care received in these settings. The group setting, community-based locations, and low cost of this model potentially reduce access barriers for those who might not

    Full Text Available Abstract Background Surgical treatment of peripheral vascular disease (PVD in dialysis patients is controversial. Methods We examined the post-operative morbidity and mortality of surgical revascularization or amputation for PVD in a retrospective analysis of United States Renal Data System. Propensity scores for undergoing amputation were derived from a multivariable logistic regression model of amputation. Results Of the Medicare patients initiated on dialysis from Jan 1, 1995 to Dec 31, 1999, patients underwent surgical revascularization (n = 1,896 or amputation (n = 2,046 in the first 6 months following initiation of dialysis were studied. In the logistic regression model, compared to claudication, presence of gangrene had a strong association with amputation [odds ratio (OR 19.0, 95% CI (confidence interval 13.86–25.95]. The odds of dying within 30 days and within1 year were higher (30 day OR: 1.85, 95% CI: 1.45–2.36; 1 yr OR: 1.46, 95% CI: 1.25–1.71 in the amputation group in logistic regression model adjusted for propensity scores and other baseline factors. Amputation was associated with increased odds of death in patients with low likelihood of amputation (rd percentile of propensity score and moderate likelihood of amputation (33rd to 66th percentile but not in high likelihood group (>66th percentile. The number of hospital days in the amputation and revascularization groups was not different. Conclusion Amputation might be associated with higher mortality in dialysis patients. Where feasible, revascularization might be preferable over amputation in dialysis patients.

    Patients with central obesity have impaired insulin-stimulated vasodilation and increased ET-1 (endothelin 1) vasoconstriction, which may contribute to insulin resistance and vascular damage. Apelin enhances insulin sensitivity and glucose disposal but also acts as a nitric oxide (NO)-dependent vasodilator and a counter-regulator of AT 1 (angiotensin [Ang] II type 1) receptor-induced vasoconstriction. We, therefore, examined the effects of exogenous (Pyr 1 )apelin on NO-mediated vasodilation and Ang II- or ET-1-dependent vasoconstrictor tone in obese patients. In the absence of hyperinsulinemia, forearm blood flow responses to graded doses of acetylcholine and sodium nitroprusside were not different during saline or apelin administration (both P >0.05). During intra-arterial infusion of regular insulin, however, apelin enhanced the vasodilation induced by both acetylcholine and nitroprusside (both P 0.05). In conclusion, in patients with central obesity, apelin has favorable effects not only to improve insulin-stimulated endothelium-dependent and endothelium-independent vasodilator responses but also to blunt Ang II- and ET-1-dependent vasoconstriction by a mechanism not involving NO. Taken together, our results suggest that targeting the apelin system might favorably impact some hemodynamic abnormalities of insulin-resistant states like obesity. © 2017 American Heart Association, Inc.

    To investigate the association between ultraearly hematoma growth (uHG) and clinical outcome in patients with spontaneous intracerebral hemorrhage (sICH) receiving hematoma evacuation. Supratentorial sICH patients receiving hematoma evacuation within 24 hours after ictus were enrolled in this study. uHG was defined as baseline hematoma volume/onset-to-computed tomography (CT) time (mL/h). The outcome was assessed by the modified Rankin Scale (mRS) score at 3 months. Unfavorable outcome was defined as mRS >2. A total of 93 patients were enrolled in this study. The mean uHG was 10.3 ± 5.5 mL/h. In 69 (74.2%) of patients, the outcome was unfavorable at 3 months. The uHG in patients with unfavorable outcome were significantly higher than in those with favorable outcome (11.0 ± 6.1 mL/h vs. 8.3 ± 2.5 mL/h, P = 0.003). The optimal cutoff of uHG for predicting unfavorable outcome was 8.7 mL/h. The sensitivity, specificity, positive predictive value, and negative predictive value of uHG >8.7 mL/h for predicting unfavorable outcome were 56.5%, 75.0%, 86.7%, and 37.5%, respectively. uHG is a helpful predictor of unfavorable outcome in sICH patients treated with hematoma evacuation. The optimal cutoff of uHG to assist in predicting unfavorable outcome in sICH patients receiving hematoma evacuation is 8.7mL/h. Copyright © 2017 Elsevier Inc. All rights reserved.

    High rates of depression and anxiety have been consistently reported among patients suffering from chronic pain. Prescription opioids are one of the most common modalities for pharmacological treatment of pain, however in recent years medical marijuana(MM) has been increasingly used for pain control in the US and in several countries worldwide. The aim of this study was to compare levels of depression and anxiety among pain patients receiving prescription opioids and MM. Participants were patients suffering from chronic pain treated with prescription opioids (OP,N=474), MM (N=329) or both (OPMM,N=77). Depression and anxiety were assessed using the depression module of the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder scale (GAD-7). Prevalence of depression among patients in the OP, MM and OPMM groups was 57.1%, 22.3% and 51.4%, respectively and rates of anxiety were 48.4%, 21.5% and 38.7%, respectively. After controlling for confounders, patients in the OP group were significantly more likely to screen positive for depression (Adjusted Odds Ratio(AOR)=6.18;95%CI=4.12-9.338) and anxiety(AOR=4.12;CI=3.84-5.71)) compared to those in the MM group. Individuals in the OPMM group were more prone for depression (AOR for depression=3.34;CI=1.52-7.34)) compared to those in the MM group. Cross-sectional study, restricting inference of causality. Levels of depression and anxiety are higher among chronic pain patients receiving prescription opioids compared to those receiving MM. Findings should be taken into consideration when deciding on the most appropriate treatment modality for chronic pain, particularly among those at risk for depression and anxiety.

    Atrial fibrillation (AF) is the most common cardiac arrhythmia, with increasing prevalence in Japan. Although prothrombin time-international normalized ratio (PT-INR) targets for monitoring warfarin therapy in patients with nonvalvular AF (NVAF) are well defined, real-world patient characteristics and PT-INR levels remain unknown among Japanese patients with NVAF who initiate and continue warfarin (warfarin maintainers) versus those who switch from warfarin to direct oral anticoagulants (DOACs; warfarin switchers). Patients with NVAF receiving oral anticoagulants between February 2013 and June 2015 were identified using a nationwide electronic medical record (EMR) database from 69 hospitals in Japan. Demographics and characteristics of patients, PT-INR, time in therapeutic range (TTR), and frequency in range (FIR) of PT-INR between warfarin maintainers and warfarin switchers were assessed. A total of 1705 patients met inclusion criteria and were examined (1501 warfarin maintainers versus 204 warfarin switchers). CHADS 2 , CHA 2 DS 2 -VASc, and HAS-BLED scores were comparable between groups. However, these scores were significantly higher among warfarin switchers at the time of switching than at the time of warfarin initiation. Furthermore, TTR and FIR of PT-INR were lower in warfarin switchers than in maintainers. Nevertheless, TTR and FIR were below 50% (PT-INR, 1.6-2.6) in both patient groups. In this EMR-based clinical study, patients who switched to DOACs had both poor or inadequate PT-INR control and higher risk factors of stroke. Many patients receiving warfarin did not achieve sufficient PT-INR therapeutic range. DOACs could be recommended in Japanese patients with NVAF with inadequate PT-INR control and increased risk of stroke. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

    Objective: To observe the incidence of anxiety in radiotherapy cancer patients in relation to their age, gender, education, marital status, performance status and type of disease. Design: Data regarding socio-demographic variables and disease type was recorded on a data capture form. The presence of anxiety was measured by administering taylor Manifest Anxiety Scale, Whereas patients, performance status was measured by administering Kernosky Performance Status Scale. Setting: Patients coming to the Department of Radiation Oncology, Shaukat Khanum Memorial Cancer Hospital and research center for their treatment were included in this study. Subjects and methods: A consecutive sample of 113 patients was taken and followed up to study the incidence of anxiety. Data over various parameters like age, gender, education, marital status, disease type and performance status was recorded. Results: Fifty percent of cancer patients receiving radiotherapy were found to be suffering from anxiety. Among 89% of patients, anxiety lowered after the therapy, in 3% it increased and remained static in 8% Patients with low education and low performance status presented with high anxiety. Among all the patients, no significant relationship between anxiety and gender, age, marital status and site of the disease was observed. Conclusion: Correlates other than radiotherapy procedure can also cause anxiety in patients by further research is required to establish those correlates of anxiety. It is recommended that all radiotherapy patients should be provided education and procedural information designed to familiarize them with the forthcoming experience in order to reduce their anxiety.

    This study piloted the use of three relaxation interventions in an attempt to reduce levels of anxiety in patients who are immobilised for radiotherapy treatment of head and neck cancers, as well as trying to validate the study methodology. In addition to receiving normal radiation therapy treatment, 14 patients were assigned to either a control group not receiving the relaxation intervention or one of three validated relaxation intervention techniques; music therapy, aromatherapy or guided imagery. Patients in the intervention groups underwent the relaxation technique daily for the first seven days of treatment. On days 1, 3, 5 and 7 of treatment patients were required to complete the State Anxiety Inventory survey. While caution should be taken in accepting the results due to the small numbers of patients involved in the study and the non-randomised assignment of patients within the study, the results of the study demonstrate a clinically significant reduction in anxiety levels in each of the three relaxation interventions compared to the control group. The study demonstrated good study validity due to the ease of implementation, the unambiguous results generated, and the use of already validated anxiety intersections and measurement tools.

    To assess which characteristics are associated with failure to receive fertility counseling among a cohort of young women diagnosed with cancer. Population-based cohort study. Not applicable. A total of 1,282 cancer survivors, of whom 1,116 met the inclusion criteria for the analysis. None. The main outcome in this study was whether or not women reported receiving any information at the time of their cancer diagnosis on how cancer treatment might affect their ability to become pregnant. Forty percent of cancer survivors reported that they did not receive fertility counseling at the time of cancer diagnosis. Women were more likely to fail to receive counseling if they had only a high school education or less or if they had given birth. Cancer-related variables that were associated with a lack of counseling included not receiving chemotherapy as part of treatment and diagnosis with certain cancer types. Counseling about the risk of infertility and available fertility preservation options is important to cancer patients. Additionally, counseling can make women aware of other adverse reproductive outcomes, such as early menopause and its associated symptoms. Less-educated women and parous women are at particular risk of not getting fertility-related information. Programs that focus on training not just the oncologist, but also other health care providers involved with cancer care, to provide fertility counseling may help to expand access.

    Mitochondria are essential for energy production in the muscle cell and for this they are dependent upon a sufficient supply of oxygen by the circulation. Exercise training has shown to be a potent stimulus for physiological adaptations and mitochondria play a central role. Whether changes in mitochondrial respiration are seen after exercise in patients with a reduced circulation is unknown. The aim of the study was to evaluate the time course and whether one session of calf raise exercise stimulates mitochondrial respiration in the calf muscle of patients with peripheral vascular disease. One group of patients with peripheral vascular disease (n = 11) and one group of healthy older adults (n = 11) were included. Patients performed one session of continuous calf raises followed by 5 extra repetitions after initiation of pain. Healthy older adults performed 100 continuous calf raises. Gastrocnemius muscle biopsies were collected at baseline and 15 minutes, one hour, three hours and 24 hours after one session of calf raise exercise. A multi substrate (octanoylcarnitine, malate, adp, glutamate, succinate, FCCP, rotenone) approach was used to analyze mitochondrial respiration in permeabilized fibers. Mixed-linear model for repeated measures was used for statistical analyses. Patients with peripheral vascular disease have a lower baseline respiration supported by complex I and they increase respiration supported by complex II at one hour post-exercise. Healthy older adults increase respiration supported by electron transfer flavoprotein and complex I at one hour and 24 hours post-exercise. Our results indicate a shift towards mitochondrial respiration supported by complex II as being a pathophysiological component of peripheral vascular disease. Furthermore exercise stimulates mitochondrial respiration already after one session of calf raise exercise in patients with peripheral vascular disease and healthy older adults.

    The aim of the study was to describe the epidemiology, clinical features, antimicrobial treatment, and outcomes of bedridden pneumonia patients receiving home healthcare. A 3-year prospective observational study of poor performance status (PS) 3-4 patients receiving long-term home healthcare and hospitalized at a single center with pneumonia between October 2010 and September 2013 was conducted, and their clinical characteristics were compared with non-bedridden community-acquired pneumonia (CAP) patients. A total of 131 CAP patients with PS 3-4, and 400 CAP patients with PS 0-2 were evaluated. The PS 3-4 patients were older, and exhibited a higher frequency of underlying diseases. Aspiration was thought to be associated with pneumonia in 77.1% of the PS 3-4 patients. Streptococcus pneumoniae was the leading pathogen in both groups, whereas the frequency of streptococci and polymicrobial infections was higher in the PS 3-4 group. The incidence of multidrug-resistant pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) or Pseudomonas aeruginosa was lower than in previous healthcare-associated pneumonia reports. The in-hospital mortality and recurrence rates were significantly higher in the PS 3-4 group than in the good PS group (17.6% vs. 6.0%, p < 0.001 and 15.3% vs. 7.5%, p = 0.008, respectively). The clinical characteristics of pneumonia in poor PS patients were similar to healthcare-associated pneumonia (HCAP), except for the frequency of drug-resistant pathogens. Hence, it might be beneficial to categorize pneumonia in home residents with poor PS separately from pneumonia in CAP patients who were previously healthy or experienced mild comorbidities.

    Full Text Available Background/Aims: The aim of the following study is to compare the behavioral and psychological symptoms of dementia (BPSD in patients of Alzheimer disease (AD and vascular dementia (VaD. Materials and Methods: We used National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer′s Disease and Related Disorders Association criteria for diagnosing AD and National Institute of Neurological Disorders and Stroke-Association International pour la Recherche et l′Enseignement en Neurosciences Criteria for diagnosing VaD. VaD cohort was further subcategorized into small vessel and large vessel disease. The severity of cognitive impairment and the BPSD were studied by means of the Clinical Dementia Rating Scale (CDR and the Neuropsychiatric Inventory respectively. Results: We studied 50 AD and 50 VaD patients of whom 38 were small vessels and 12 were large vessels VaD. The severity of dementia was comparable in both groups. The agitation/aggression, depression/dysphoria, anxiety, apathy/indifference, irritability, aberrant motor behavior, appetite and eating behavior and night-time behaviors occurred significantly more frequently in patients with VaD than AD. We found a weak positive correlation between the CDR score and the number of neuropsychiatric symptoms per patient in both cohorts. Elation/euphoria, agitation/aggression was significantly more frequent in patients with large vessel in comparison to small vessel VaD. Conclusions: BPSD are common in both types of dementia and they are more severe in VaD than AD when the groups have similar levels of cognitive impairment.

    Compounding pharmacies often prepare parenteral nutrition (PN) and must adhere to rigorous standards to avoid contamination of the sterile preparation. In March 2011, Serratia marcescens bloodstream infections (BSIs) were identified in 5 patients receiving PN from a single compounding pharmacy. An investigation was conducted to identify potential sources of contamination and prevent further infections. Cases were defined as S. marcescens BSIs in patients receiving PN from the pharmacy between January and March 2011. We reviewed case patients' clinical records, evaluated pharmacy compounding practices, and obtained epidemiologically directed environmental cultures. Molecular relatedness of available Serratia isolates was determined by pulsed-field gel electrophoresis (PFGE). Nineteen case patients were identified; 9 died. The attack rate for patients receiving PN in March was 35%. No case patients were younger than 18 years. In October 2010, the pharmacy began compounding and filter-sterilizing amino acid solution for adult PN using nonsterile amino acids due to a national manufacturer shortage. Review of this process identified breaches in mixing, filtration, and sterility testing practices. S. marcescens was identified from a pharmacy water faucet, mixing container, and opened amino acid powder. These isolates were indistinguishable from the outbreak strain by PFGE. Compounding of nonsterile amino acid components of PN was initiated due to a manufacturer shortage. Failure to follow recommended compounding standards contributed to an outbreak of S. marcescens BSIs. Improved adherence to sterile compounding standards, critical examination of standards for sterile compounding from nonsterile ingredients, and more rigorous oversight of compounding pharmacies is needed to prevent future outbreaks.

    Clinical outcomes after a hospital discharge are poorly defined for patients receiving maintenance in-center (outpatient) hemodialysis. To describe the proportion and characteristics of these patients who are rehospitalized, visit an emergency department, or die within 30 days after discharge from an acute hospitalization, we conducted a population-based study of all adult patients receiving maintenance in-center hemodialysis who were discharged between January 1, 2003, and December 31, 2011, from 157 acute care hospitals in Ontario, Canada. For patients with more than one hospitalization, we randomly selected a single hospitalization as the index hospitalization. Of the 11,177 patients included in the final cohort, 1926 (17%) were rehospitalized, 2971 (27%) were treated in the emergency department, and 840 (7.5%) died within 30 days of discharge. Complications of type 2 diabetes mellitus were the most common reason for rehospitalization, whereas heart failure was the most common reason for an emergency department visit. In multivariable analysis using a cause-specific Cox proportional hazards model, the following characteristics were associated with 30-day rehospitalization: older age, the number of hospital admissions in the preceding 6 months, the number of emergency department visits in the preceding 6 months, higher Charlson comorbidity index score, and the receipt of mechanical ventilation during the index hospitalization. Thus, a large proportion of patients receiving maintenance in-center hemodialysis will be readmitted or visit an emergency room within 30 days of an acute hospitalization. A focus on improving care transitions from the inpatient setting to the outpatient dialysis unit may improve outcomes and reduce healthcare costs.

    Purpose: Photon therapy has been reported to induce resets of implanted cardiac devices, but the clinical sequelae of treating patients with such devices with proton beam therapy (PBT) are not well known. We reviewed the incidence of device malfunctions among patients undergoing PBT. Methods and Materials: From March 2009 through July 2012, 42 patients with implanted cardiac implantable electronic devices (CIED; 28 pacemakers and 14 cardioverter-defibrillators) underwent 42 courses of PBT for thoracic (23, 55%), prostate (15, 36%), liver (3, 7%), or base of skull (1, 2%) tumors at a single institution. The median prescribed dose was 74 Gy (relative biological effectiveness; range 46.8-87.5 Gy), and the median distance from the treatment field to the CIED was 10 cm (range 0.8-40 cm). Maximum proton and neutron doses were estimated for each treatment course. All CIEDs were checked before radiation delivery and monitored throughout treatment. Results: Median estimated peak proton and neutron doses to the CIED in all patients were 0.8 Gy (range 0.13-21 Gy) and 346 Sv (range 11-1100 mSv). Six CIED malfunctions occurred in 5 patients (2 pacemakers and 3 defibrillators). Five of these malfunctions were CIED resets, and 1 patient with a defibrillator (in a patient with a liver tumor) had an elective replacement indicator after therapy that was not influenced by radiation. The mean distance from the proton beam to the CIED among devices that reset was 7.0 cm (range 0.9-8 cm), and the mean maximum neutron dose was 655 mSv (range 330-1100 mSv). All resets occurred in patients receiving thoracic PBT and were corrected without clinical incident. The generator for the defibrillator with the elective replacement indicator message was replaced uneventfully after treatment. Conclusions: The incidence of CIED resets was about 20% among patients receiving PBT to the thorax. We recommend that PBT be avoided in pacing-dependent patients and that patients with any type of CIED receiving

    Full Text Available The article is dedicated to diagnostics and treatment of infectious complications among children with juvenile rheumatoid arthritis, receiving immunosuppressive therapy. The research involves 92 children with different variants of the illness run, who received immunosuppressive therapy. All the patients showed development of the systemic inflammatory response manifestations. The researchers used the definition of the procalcytonine levels as a marker for the bacterial infectiondevelopment. All the patients showed it higher than 0,5 ng/ml, while 7 patients — higher than 10 ng/ml. keeping in mind several courses of the antibacterial therapy in the anamnesis and presence of the combined bacterial infection, ceftriaxone was prescribed to all the children. As a result of the ceftriaxone based therapy, reduction of the clinical and laboratory manifestations of the bacterial infection was noted among more than 90% of patients. The development of the allergic reaction was noted in 1 case, and leukopenia was also found in 1 patient.Key words: children, juvenile rheumatoid arthritis, ceftriaxone.

    Full Text Available OBJECTIVE: Determine the prevalence of metabolic abnormalities (MA and estimate the 10-year risk for cardiovascular disease (CVD among Latin American HIV-infected patients receiving highly active anti-retroviral therapy (HAART. METHODS: A cohort study to evaluate MA and treatment practices to reduce CVD has been conducted in seven Latin American countries. Adult HIV-infected patients with at least one month of HAART were enrolled. Baseline data are presented in this analysis. RESULTS: A total of 4,010 patients were enrolled. Mean age (SD was 41.9 (10 years; median duration of HAART was 35 (IQR: 10-51 months, 44% received protease inhibitors. The prevalence of dyslipidemia and metabolic syndrome was 80.2% and 20.2%, respectively. The overall 10-year risk of CVD, as measured by the Framingham risk score (FRF, was 10.4 (24.7. Longer exposure to HAART was documented in patients with dyslipidemia, metabolic syndrome and type 2 diabetes mellitus. The FRF score increased with duration of HAART. Male patients had more dyslipidemia, high blood pressure, smoking habit and higher 10-year CVD than females. CONCLUSIONS: Traditional risk factors for CVD are prevalent in this setting leading to intermediate 10-year risk of CVD. Modification of these risk factors through education and intervention programs are needed to reduce CVD.

    It has rarely been reported about the changes of hemoglobin (Hb) and hematocrit (Hct) in elderly patients receiving total knee arthroplasty (TKA) or total hip arthroplasty (THA). This study aimed to evaluate the changes of Hb and Hct after TKA or THA in elderly patients, and analyze its relationship with sex and type of arthroplasty. This is a prospective cohort study, including 107 patients receiving TKA or THA without allogeneic blood transfusion. There were 54 males and 53 females, with a mean age of 69.42 years. Levels of Hb and Hct were examined preoperatively and during the 6 months follow-up after operation. Levels of Hb and Hct decreased postoperatively and reached their minimum points on postoperative day 4. Thereafter, Hb and Hct recovered to their preoperative levels within 6-12 weeks. No significant differences in the levels of Hb and Hct were noticed between different sexes. THA patients showed significantly greater drop in Hb and Hct than TKA patients in the first 4 days postoperatively (P < 0.05). Levels of Hb and Hct decreased during the first 4 days after arthroplasty and gradually returned to their normal levels within 6-12 weeks postoperatively. THA may be associated with higher postoperative blood loss than TKA.

    In 15 months we encountered eight patients with intracranial tumors who developed erythema multiforme (EM) or erythema multiforme bullosa (Stevens-Johnson syndrome). All occurred shortly after use of phenytoin (DPH) and brain radiation therapy (WBRT). The clinical picture differed from the classic form of EM in that the erythema began on the scalp and spread to the extremities, progressing in three cases to extensive bullous formation. There were no cases of EM among patients who received either DPH or radiotherapy alone. The combination of DPH, WBRT, and tapering of steroids seems to predispose to EM. The pathogenesis of the disorder is probably immunologic. In the absence of seizures, anticonvulsants should not be given routinely to patients with brain tumors. When anticonvulsants are necessary in patients scheduled for WBRT, DPH may not be the drug of choice

    Objective: To discuss the application of nursing care in CT-guided percutaneous biopsy of the pancreas. Methods: The perioperative nursing measures were carried out in 21 patients receiving percutaneous biopsy of the pancreas under CT-guidance. Active, effective and comprehensive nursing procedures were adopted to closely cooperate with the whole process of percutaneous biopsy as far as possible. Results: All the patients could actively cooperate with the physician during the whole process of percutaneous biopsy and the surgery was successfully completed in all patients. The technical success rate with only single puncture was 100%. No obvious complications occurred after the procedure. Conclusion: In order to ensure that the patient will be able to cooperate with the CT-guided percutaneous biopsy of the pancreas, that the operation time can be shortened and that the postoperative complications can be avoided, perioperative nursing care is indispensable.

    Clinical concern over significant cardiotoxicity of commonly employed chemotherapeutic regimens is a common indication for gated blood pool imaging. The authors have undertaken a review of 102 patients referred for such evaluation during a 14-month period. Ventricular ejection fractions, cine displays, and phase analysis were performed on each patient study. Approximately one-third of the cases showed significant abnormalities in wall motion or global ejection fraction. Many abnormal cases had isolated left ventricular findings, while fewer had isolated right ventricular findings. Left ventricular wall motion abnormalities were often focal. The patterns of ventricular dysfunction in patients receiving cardiotoxic chemotherapy are diverse, and awareness of the various possibilities is important for accurate clinical assessment of these patients

    Background and study aims  Recent literature suggests that chemo(radio)therapy might reduce the patency of plastic stents in patients with malignant biliary obstruction. Whether this might also be valid for other types of stents is unknown. The aim of this study was to determine the influence of chemo(radio)therapy on the patency of fully-covered self-expandable metal stents (FCSEMSs) and plastic stents. Patients and methods  We retrospectively reviewed the electronic medical records of patients with distal malignant biliary obstruction who underwent biliary stent placement between April 2001 and July 2015. Primary outcome was duration of stent patency. Secondary outcome was stent patency at 3 and 6 months. We used Kaplan–Meier survival analyses to compare stent patency rates between patients who received chemo(radio)therapy and patients who did not. Results  A total of 291 biliary stents (151 metal and 140 plastic) were identified. The median cumulative stent patency of FCSEMSs did not differ between patients receiving chemo(radio)therapy (n = 51) and those (n = 100) who did not ( P  = 0.70, log-rank test). The estimated cumulative stent patency of plastic stents was also comparable in 99 patients without and 41 patients with chemo(radio)therapy ( P  = 0.73, log-rank test). At 3 and 6 months, FCSEMS patency rates were 87 % and 83 % in patients without chemo(radio)therapy and 96 % and 83 % in patients with therapy, respectively. Plastic patency rates were 69 % and 55 % in patients without and 85 % and 39 % in patients with therapy, respectively. After 1 year, 78 % of the FCSEMSs were still patent in patients without chemo(radio)therapy and 69 % of the FCSEMSs were still patent in patients with therapy. Conclusion  Our data indicate that chemo(radio)therapy does not reduce the patency of biliary fully-covered metal and plastic stents. PMID:29090242

    Adherence to rehabilitation exercise is much lower in patients with hematologic malignancies (22.5-45.8%) than in patients with solid tumors (60-85%) due to the administration of more intensive chemotherapeutic regimens in the former. Virtual reality exercise can be performed even in a biological clean room and it may improve the adherence rates in elderly patients with hematologic malignancies. Thus, in this pilot study, we aimed to investigate the feasibility and safety of virtual reality exercise intervention using Nintendo Wii Fit in patients with hematologic malignancies receiving chemotherapy. In this feasibility study, 16 hospitalized patients with hematologic malignancies aged ≥60 years performed virtual reality exercise for 20 minutes using the Nintendo Wii Fit once a day, five times a week, from the start of chemotherapy until hospital discharge. The adherence rate, safety, and physical and psychological performances were assessed. The adherence rate for all 16 patients was 66.5%. Nine patients completed the virtual reality exercise intervention with 88 sessions, and the adherence rate was 62.0%. No intervention-related adverse effects >Grade 2, according to National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0, were observed. We noted maintenance of the physical performance (e.g., Barthel index, handgrip strength, knee extension strength, one-leg standing time, and the scores of timed up and go test and Instrumental Activities of Daily Living) and psychosocial performance (e.g., score of hospital anxiety and depression scale). Virtual reality exercise using the Wii Fit may be feasible, safe and efficacious, as demonstrated in our preliminary results, for patients with hematologic malignancies receiving chemotherapy.

    Full Text Available BACKGROUND: Oropharyngeal candidiasis is a common infection in patient receiving radiotherapy for head and neckcancer. Accurate and rapid identification of candida species is very important in clinical laboratory, because theincidence of candidiasis continues to rise after radiotherapy. The genus Candida has about 154 species that showdifferent level of resistance to antifungal drugs and have high degree of phenotypic similarity. The aim of this study wasto investigate oral yeast colonization and infection and resistance to antifungal drugs in these patients.METHODS: Thirty patients receiving a 6-week course of radiation therapy for treatment of head and neck cancer at theOncology Unit in Shafa Hospital, in 2008, were enrolled in the study. Specimens from patients were cultured weeklyfor Candida. All isolates were plated on CHROM agar and RPMI-based medium. They were subcultured and submittedfor antifungal susceptibility testing (nystatin, fluconazole, clotrimazole and ketoconazole and molecular typing.RESULTS: Infection (clinical and microbiological evidence occurred in 50% of the patients and Candida colonization(only microbiological evidence occurred in 70% of subjects in the first week. Candida albicans alone was isolated in94.9% of patient visits with positive cultures. Candida tropicalis was isolated from 5.1% of patient visits with positivecultures. All isolates were susceptible to nystatin, but did not respond to the other antifungal drugsCONCLUSIONS: The irradiation-induced changes of the intraoral environment such as xerostomia lead to increasedintraoral colonization by Candida species. All yeast isolates were susceptible to nystatin. Thus prophylactic therapywith nystatin should be considered for these patients.

    To survey a large sample of type 2 diabetes mellitus (T2DM) patients in Mexico City to determine if patient experience, access to basic services, treatment, and outcomes differed between those with social security coverage and those without. From 2001-2007 a total of 1 000 individuals with T2DM were surveyed in outpatient clinics of the three largest public ophthalmology hospitals in Mexico City. Patients reported information about their health status and receipt of basic diabetes services, such as laboratory glycemic monitoring and diabetes education. Rates were compared between those with (n = 461) and without (n = 539) social security. Almost half of the patients (46%) in these public facilities were social security patients that were unable to access other services and had to pay out-of-pocket for care. Half of respondents were originally identified as potentially diabetic based on symptom complaints (51%), including 11% with visual impairment. Most patients (87.9%) reported that their glycemic level was being monitored exclusively via fasting blood glucose testing or random capillary blood glucose tests; only 5.3% reported ever having a glycated hemoglobin test. While nearly all respondents reported an individual physician encounter ever, only 39% reported ever receiving nutrition counseling and only 21% reported attending one or more sessions of diabetes education in their lifetime. Processes of care and outcomes were no different in patients with and those without social security coverage. In Mexico, the quality of diabetes care is poor. Despite receiving social security, many patients still have to pay out-of-pocket to access needed care. Without policy changes that address these barriers to comprehensive diabetes management, scientific achievements in diagnosis and pharmacotherapy will have limited impact.

    Full Text Available Summary: Background: Given the global increase in aging populations and cancer incidence, understanding the influence of age on postoperative outcome after cancer surgery is imperative. This study aimed to evaluate the impact of age on survival outcome in solid cancer patients receiving curative surgery. Methods: A total of 37,288 patients receiving curative surgeries for solid cancers between 2007 and 2012 at four affiliated Chang Gung Memorial Hospital were included in the study. All patients were categorized into age groups by decades for survival analysis. Results: The percentages of patient populations aged <40 years, 40–49 years, 50–59 years, 60–69 years, 70–79 years, and ≥80 years were 9.7%, 17.7%, 27.8%, 22.1%, 16.9%, and 5.7%, respectively. The median follow-up period was 38.9 months (range, 22.8–60.4 months and the overall, cancer-specific, and noncancer-specific mortality rates were 26.0%, 17.6%, and 8.5%, respectively. The overall mortality rate of patients in different age groups were 18.5%, 21.1%, 22.0%, 25.3%, 35.3%, and 49.0%, respectively. Compared to patients aged <40 years, more significant decrease in long-term survival were observed in aging patients. Multivariate analysis showed higher postoperative short-term mortality rates in patients older than 70 years, and the adjusted odds ratio of mortality risk ranged from 1.47 to 1.74 and 2.26 to 3.03 in patients aged 70–79 years and ≥80 years, respectively, compared to those aged <40 years. Conclusion: Aging was a negative prognostic factor of survival outcome in solid cancer patients receiving curative surgery. After adjustment of other clinicopathologic factors, the influence of age on survival outcome was less apparent in the elderly. Keywords: Age, Solid cancer, Surgical resection, Prognosis

    The aim of this investigation is to quantify periodontal pathogens (Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Campylobacter rectus, and Tannerella forsythia) in vascular, blood, and subgingival samples. As a secondary objective, two molecular bacterial identification methods (nested polymerase chain reaction [PCR] and quantitative PCR [qPCR]) are compared. Seventy consecutive patients provided a vascular lesion, a blood sample, and 36 subgingival samples. Bacterial DNA was extracted, and qPCR was used to determine the prevalence and amounts of the target pathogens in each sample. Nested PCR was performed only in the samples from vascular lesions. Periodontal examination was performed in 42 patients. Mann-Whitney U or χ(2) tests were used to compare microbiologic results according to periodontal diagnosis. All targeted periodontal pathogens (A. actinomycetemcomitans, P. gingivalis, T. forsythia, or C. rectus) were detected in subgingival samples, with a prevalence rate of 72.2%, 47.2%, 74.3%, and 82.9%, respectively. In 7.1% and 11.4% of vascular and blood samples, bacterial DNA was detected. One patient was positive for A. actinomycetemcomitans in the three types of samples. No differences were found in the levels of targeted bacteria when comparing patients with and without periodontitis. Prevalence rates obtained with nested PCR were significantly higher than those obtained with qPCR. The presence of A. actinomycetemcomitans was demonstrated in vascular, blood, and subgingival samples in one of 36 patients. These results, although with a very low frequency, may support the hypothesis of a translocation of periodontal pathogens from subgingival microbiota to the bloodstream and then to atheromatous plaques in carotid or other peripheral arteries. Nested PCR is not an adequate method for identifying DNA of periodontal pathogens in low quantities because of the high number of false-negative results.

    Neuronal system activity plays an important role for the prognosis of patients with atrial fibrillation (AF). Using 123 I metaiodobenzylguanidine ( 123 I-MIBG) scintigraphy, we investigated whether a cardiac sympathetic nervous system (SNS) abnormality would be associated with an increased risk of vascular events in patients with paroxysmal AF. 123 I-MIBG scintigraphy was performed in 69 consecutive patients (67 ± 13 years, 62% men) with paroxysmal AF who did not have structural heart disease. SNS integrity was assessed from the heart to mediastinum (H/M) ratio on delayed imaging. Serum concentration of C-reactive protein (CRP) was measured before 123 I-MIBG study. During a mean of 4.5 ± 3.6 years follow-up, 19 patients had myocardial infarction, stroke or heart failure (range: 0.2-11.5 years). SNS abnormality (H/M ratio <2.7) and high CRP (≥0.3 mg/dl) were associated with the vascular events (58.3% in 14 of 24 patients with SNS abnormality vs 11.1% in 5 of 45 patients without SNS abnormality, p < 0.0001, 52.4% in 11 of 21 patients with high CRP vs 16.7% in 8 of 48 patients without high CRP, p < 0.0001). After adjustment for potential confounding variables such as age, left atrial dimension and left ventricular function, SNS abnormality was an independent predictor of vascular events with a hazard ratio of 4.1 [95% confidence interval (CI): 1.3-12.6, p = 0.014]. Further, SNS abnormality had an incremental and additive prognostic power in combination with high CRP with an adjusted hazard ratio of 4.1 (95% CI: 1.5-10.9, p = 0.006). SNS abnormality is predictive of vascular events in patients with idiopathic paroxysmal AF. (orig.)

    To determine whether genetic or acquired thrombophilias and other risk factors are associated with nonarteritic anterior ischemic optic neuropathy (NAION). Retrospective case-control study. Sixty-one patients with NAION diagnosed between 1984 and 1997. Ninety consecutive patients who visited the Eye Institute made up the control group. Protein C, protein S, antithrombin III, lupus anticoagulant, and three recently described prothrombotic polymorphisms (i.e., factor V G1691A, factor II G20210A, and methylenetetrahydrofolate reductase [MTHFR] C677T) were analyzed. In addition, risk factors for arteriosclerotic vascular disease were assessed. Parameters of thrombophilia. None of the thrombophilic markers (genetic and acquired) constituted a significant risk factor for NAION. Ischemic heart disease, hypercholesterolemia, and diabetes mellitus were discerned as risk factors for NAION with odds ratios of 2.9 (95% confidence interval [CI], 1.3-6.4), 2.6 (95% CI, 1.2-5.5), and 2.3 (95% CI, 1.1-4.8), respectively. Multiple logistic regression analysis indicated that ischemic heart disease and hypercholesterolemia exerted an additive risk for NAION with a combined odds ratio of 4.5 (95% CI, 1.4-14.5). However, none of these risk factors statistically predicted second eye involvement. NAION was not found to be associated with thrombophilic risk factors, yet it was related to ischemic heart disease, hypercholesterolemia, and diabetes mellitus.

    Full Text Available Background. The contribution of the hemodialysis (HD vascular access type to inflammation is unclear. Methods. We conducted a prospective observational study in an incident HD population. C-reactive protein (CRP, interleukin-6 (IL-6, and interferon-γ-induced protein (IP-10 were measured before and at 6-time points after access placement for 1 year. Results. Sixty-four incident HD patients were included (tunneled catheter (TC, =40, arteriovenous fistula (AVF, =14, and arteriovenous graft (AVG, =10. A mixed effects model was performed to adjust for age, sex, race, coronary artery disease, diabetes mellitus, infections, access thrombosis, initiation of HD, and days after access surgery. In comparison to AVFs, the presence of a TC was associated with significantly higher levels of CRP (=0.03, IL-6 (=0.07, and IP-10 (=0.03. The presence of an AVG was associated with increases in CRP (=0.01 and IP-10 (=0.07. Conclusions. Patients who initiate HD with a TC or an AVG have a heightened state of inflammation, which may contribute to the excess 90-day mortality after HD initiation.

    We investigated Doppler ultrasonographic (US) parameters of patients with acute stroke to predict the cerebral vascular reserve (CVR) measured by SPECT. We reviewed the flow velocity and cross-sectional area of the circular vessel at the common, external, and internal carotid arteries (ICA) and the vertebral arteries (VA) in 109 acute stroke patients who underwent SPECT. Flow volume (FV) of each artery was calculated as the product of the angle-corrected time averaged flow velocity and cross-sectional area of the circular vessel. Total cerebral FV (TCBFV) was determined as the sum of the FVs of the right and left ICA and VA. We compared the Doppler US parameters between 44 cases of preserved and 65 cases of impaired CVR. In the preserved CVR group, ICA FV, anterior circulating FV (ACFV) and TCBFV were higher than in the impaired CVR group (p < 0.05, independent t-test). In the impaired CVR group, the ROC curves showed ACFV and TCBFV were suitable parameters to predict CVR (p < 0.05). Doppler US was helpful for understanding the hemodynamic state of acute stroke. FV measurement by Doppler US was useful for predicting CVR

    Background In ESCAPE, there was no difference in days alive and out of the hospital for patients with decompensated heart failure (HF) randomly assigned to therapy guided by pulmonary artery catheter (PAC) plus clinical assessment versus clinical assessment alone. The external validity of these findings is debated. Methods and Results ESCAPE sites enrolled 439 patients receiving PAC without randomization in a prospective registry. Baseline characteristics, pertinent trial exclusion criteria, reasons for PAC use, hemodynamics, and complications were collected. Survival was determined from the National Death Index and the Alberta Registry. On average, registry patients had lower blood pressure, worse renal function, less neurohormonal antagonist therapy, and higher use of intravenous inotropes as compared with trial patients. Although clinical assessment anticipated less volume overload and greater hypoperfusion among the registry population, measured filling pressures were similarly elevated in the registry and trial, while measured perfusion was slightly higher among registry patients. Registry patients had longer hospitalization (13 vs. 6 days, p <0.001) and higher 6-month mortality (34% vs. 20%, p < 0.001) than trial patients. Conclusions The decision to use PAC without randomization identified a population with higher disease severity and risk of mortality. This prospective registry highlights the complex context of patient selection for randomized trials. PMID:18926438

    To explore the experiences of patients receiving oral anticancer agents. A qualitative study using semistructured interviews with a grounded theory approach. A university hospital in Japan. 14 patients with gastric cancer who managed their cancer with oral anticancer agents. Patients with cancer experienced inner conflict between rational belief and emotional resistance to taking medication due to confrontation with cancer, doubt regarding efficacy and concerns over potential harm attached to use of the agent. Although they perceived themselves as being adherent to medication, they reported partial non-adherent behaviours. The patients reassessed their lives through the experience of inner conflict and, ultimately, they recognised their role in medication therapy. Patients with cancer experienced inner conflict, in which considerable emotional resistance to taking their medication affected their occasional non-adherent behaviours. In patient-centred care, it is imperative that healthcare providers understand patients' inner conflict and inconsistency between their subjective view and behaviour to support patient adherence.

    Background and purpose: The diagnosis and treatment of breast cancer can cause considerable psychological consequences, which may remain unrecognized and untreated. In this study, the prevalence of depressive symptoms and distress, and unmet needs for psychosocial support were assessed among breast cancer patients receiving postoperative radiotherapy. Material and methods: Out of 389 consecutive patients, 276 responded and comprised the final study group. Depressive symptoms were assessed with the Beck Depression Inventory. Distress was measured with the Distress Thermometer. Hospital records of the patients were examined for additional information. Results: Nearly one third of patients (32.1%) displayed depressive symptoms, and more than a quarter of patients (28.4%) experienced distress. Younger age (p = 0.001) and negative hormone receptor status (p = 0.008) were independent factors associated with distress. One quarter of the patients expressed an unmet need for psychosocial support, which was independently associated with depressive symptoms and/or distress (p = 0.001) and younger age (p = 0.006). Conclusions: During radiotherapy for breast cancer, the staff should have awareness of the higher risk of depression and distress in their patients and should consider screening tools to recognise distress and depressive symptoms. Special attention should be paid to younger patients.

    2018-03-26

    This was a single center, retrospective cross-sectional study looking into the incidence and types of drug-related problems (DRPs) detected among elderly cancer patients receiving at least three long-term medications concurrent with IV chemotherapy, and the types of intervention taken to address these DRPs. This paper serves to elucidate the prevalence and risk of polypharmacy in our geriatric oncology population in an ambulatory care setting, to raise awareness on this growing issue and to encourage more resource allocation to address this healthcare phenomenon. DRP was detected in 77.6% of elderly cancer patients receiving at least three long-term medications concurrent with IV chemotherapy, with an average incidence of three DRPs per patient. Approximately half of DRPs were related to long-term medications. Forty percent of DRPs required interventions at the prescriber level. The use of five or more medications was shown to almost double the risk of DRP occurrence (OR 1.862, P = 0.039). Out of the eight predefined categories of DRPs, underprescribing was the most common (26.7%), followed by adverse drug reaction (25.0%) and drug non-adherence (16.2%). Polypharmacy leading to DRPs is a common occurrence in elderly cancer patients receiving outpatient IV chemotherapy. There should be systematic measures in place to identify patients who are at greater risk of inappropriate polypharmacy and DRPs, and hence more frequent drug therapy optimization and monitoring. The identification of DRPs is an important step to circumvent serious drug-related harm. Future healthcare interventions directed at reducing DRPs should aim to assess the clinical and economic impact of such interventions.

    Alzheimer's Disease (AD) and Vascular Dementia (VaD) are the most common causes of dementia in older people. Both diseases appear to have similar clinical symptoms, such as deficits in attention and executive function, but specific cognitive domains are affected. Current cohort studies have shown a close relationship between αβ deposits and age-related macular degeneration (Johnson et al., 2002; Ratnayaka et al., 2015). Additionally, a close link between the thinning of the retinal nerve fiber (RNFL) and AD patients has been described, while it has been proposed that AD patients suffer from a non-specific type of color blindness (Pache et al., 2003). Our study included 103 individuals divided into three groups: A healthy control group (n = 35), AD (n = 32) according to DSM-IV-TR, NINCDS-ADRDA criteria, and VaD (n = 36) based on ΝΙΝDS-AIREN, as well as Magnetic Resonance Imaging (MRI) results. The severity of patient's cognitive impairment, was measured with the Mini-Mental State Examination (MMSE) and was classified according to the Reisberg global deterioration scale (GDS). Visual perception was examined using the Ishihara plates: "Ishihara Color Vision Test - 38 Plate." The three groups were not statistically different for demographic data (age, gender, and education). The Ishihara color blindness test has a sensitivity of 80.6% and a specificity of 87.5% to discriminate AD and VaD patients when an optimal (32.5) cut-off value of performance is used. Ishihara Color Vision Test - 38 Plate is a promising potential method as an easy and not time-consuming screening test for the differential diagnosis of dementia between AD and VaD.

    BACKGROUND.: Lung cancer is the leading cause of cancer deaths. Angiogenesis is crucial process in cancer growth and progression. This prospective study evaluated expression of two central regulatory molecules: angiogenin and vascular endothelial growth factor (VEGF) in patients with lung cancer. PATIENTS AND METHODS.: Clinical data, blood samples and broncho-alveolar lavage (BAL) from 23 patients with primary lung carcinoma were collected. BAL fluid was taken from part of the lung with malignancy, and from corresponding healthy side of the lung. VEGF and angiogenin concentrations were analysed by an enzyme-linked immunosorbent assay. Dilution of bronchial secretions in the BAL fluid was calculated from urea concentration ratio between serum and BAL fluid. RESULTS.: We found no statistical correlation between angiogenin concentrations in serum and in bronchial secretions from both parts of the lung. VEGF concentrations were greater in bronchial secretions in the affected side of the lung than on healthy side. Both concentrations were greater than serum VEGF concentration. VEGF concentration in serum was in positive correlation with tumour size (p = 0,003) and with metastatic stage of disease (p = 0,041). There was correlation between VEGF and angiogenin concentrations in bronchial secretions from healthy side of the lung and between VEGF and angiogenin concentrations in bronchial secretions from part of the lung with malignancy. CONCLUSION.: Angiogenin and VEGF concentrations in systemic, background and local samples of patients with lung cancer are affected by different mechanisms. Pro-angiogenic activity of lung cancer has an important influence on the levels of angiogenin and VEGF.

    Full Text Available Background: Serum N-terminal pro-brain natriuretic peptide (NT-proBNP is regarded as a sensitive marker of cardiovascular disease. Vascular disease plays an important role in cognitive impairment. Method: In 447 elderly patients with mental illness, serum NT-proBNP level and the presence or absence of vascular disease according to the medical record were used to categorize patients in different subgroups of vascular disease. Results and Conclusion: Patients with vascular disease and elevated serum NT-proBNP level had a lower cognition level, shorter survival time, lower renal function and a higher percentage of pathological brain imaging than patients with vascular disease and normal NT-proBNP level. Thus, elevated serum NT-proBNP level might be helpful to detect patients who have a more severe cardiovascular disease.

    Full Text Available Vascular access thrombosis is one of the major causes of morbidity in patients maintained on chronic hemodialysis. Thrombophilia has been recognized as a risk factor of vascular access thrombosis. The authors report a case of inherited protein S deficiency associated with vascular access thrombotic events. DNA sequence analysis of the PROS1 gene identified a novel heterozygous nonsense mutation in exon 10 by transition of AAG (lysine to TAG (stop codon at codon 473 (c.1417A>T, p.K473X. Results from the study suggest that the inherited protein S deficiency due to a PROS1 gene mutation may cause vascular access thrombosis in hemodialysis patients.

    This study evaluates differences in wound complication rate when transverse versus longitudinal incision is utilized to expose femoral vessels in managing patients with peripheral vascular disease. A retrospective review from 2013 to 2015 was conducted of 150 patients undergoing 156 lower extremity revascularizations with femoral artery exposure through a groin incision. Patients were stratified into 2 groups, transverse versus longitudinal groin incision. Data were reviewed for 3 surgeons that utilize either transverse or longitudinal groin incision in patients undergoing common or iliofemoral endarterectomies, or where femoral artery was used as inflow and/or outflow vessel for limb revascularization. Each group had a comparative outcomes analysis based on incision type. The primary outcome was wound complication, defined as any wound infection, lymphocele, hematoma, dehiscence, pseudoaneurysm, or necrosis. Other outcomes studied included unplanned return to operating room for wound complication, wound vacuum therapy, and soft-tissue flap closure. Data were analyzed using 2-tailed chi-squared test and Student's t-test. Patients in the transverse (n = 85 cases) versus longitudinal (n = 71 cases) cohorts were similar in relation to demographics and comorbidities. Overall mean follow-up was 220 days. Patients with a transverse as compared to longitudinal incision had a significantly lower overall wound complication rate, 7% vs. 42%, respectively (P transverse incisions were associated with lower incidence of unplanned return to the operating room to manage wound complications than patients with a longitudinal incision (5% vs. 23%, respectively; P Transverse versus longitudinal incisions were also associated with significantly lower need for wound vacuum therapy (6% vs. 15%, respectively; P Transverse groin incisions for femoral artery exposure may offer a lower risk of wound complications for open procedures as compared to a longitudinal incision

    Conclusion: Survival analysis using Cox regression showed that the average consumption of opioids played an important role in postoperative nausea and vomiting, a result not found by logistic regression. Therefore, the incidence of postoperative nausea and vomiting in patients cannot be reliably determined on the basis of a single visit at one point in time.

    Context Serum creatinine has been reported to increase in patients receiving Vemurafenib, yet neither the prevalence nor the mechanism of this adverse event are known. Objective We aimed to evaluate the frequency and the mechanisms of increases in plasma creatinine level in patients receiving Vemurafenib for advanced melanoma. Methods We performed a retrospective monocentric study including consecutive patients treated with Vemurafenib for an advanced melanoma. We collected clinical and biological data concerning renal function before introduction of Vemurafenib and in the course of monthly follow-up visits from March 2013 to December 2014. Cystatin C-derived glomerular filtration rate was evaluated before and after Vemurafenib initiation, as increase in serum cystatin C is specific to a decrease in the glomerular filtration rate. We also performed thorough renal explorations in 3 patients, with measurement of tubular secretion of creatinine before and after Vemurafenib initiation and a renal biopsy in 2 patients. Results 70 patients were included: 97% of them displayed an immediate, and thereafter stable, increase in creatinine (+22.8%) after Vemurafenib initiation. In 44/52 patients in whom Vemurafenib was discontinued, creatinine levels returned to baseline. Serum cystatin C increased, although proportionally less than serum creatinine, showing that creatinine increase under vemurafenib was indeed partly due to a renal function impairment. In addition, renal explorations demonstrated that Vemurafenib induced an inhibition of creatinine tubular secretion. Conclusion Thus, Vemurafenib induces a dual mechanism of increase in plasma creatinine with both an inhibition of creatinine tubular secretion and slight renal function impairment. However, this side effect is mostly reversible when Vemurafenib is discontinued, and should not lead physicians to discontinue the treatment if it is effective. PMID:26930506

    The antiemetic effects and safety of granisetron and palonosetron against chemotherapy-induced nausea and vomiting (CINV) were retrospectively evaluated in patients with non-Hodgkin lymphoma receiving bendamustine-based chemotherapy. A total of 61 patients were eligible for this study. Before starting the bendamustine-based chemotherapy, granisetron or palonosetron were intravenously administered with or without aprepitant and/or dexamethasone. The proportions of patients with complete control (CC) during the overall (during the 6 days after the start of the chemotherapy), acute (up to 2 days), and delayed (3 to 6 days) phases were assessed. CC was defined as complete response with only grade 0-1 nausea, no vomiting, and no use of antiemetic rescue medication. Granisetron or palonosetron alone were administered to 9 and 19 patients, respectively. Aprepitant and/or dexamethasone were combined with granisetron and palonosetron in 28 and 5 patients, respectively. Acute CINV was completely controlled in all patients. Both granisetron monotherapy and palonosetron combination therapy could provide good control of delayed CINV, although the CC rates during the delayed and overall phases were not significantly different among mono- and combination therapy of the antiemetics. There was no significant difference in the frequencies of adverse drug events between the granisetron and palonosetron treatment groups. The present study showed that the antiemetic efficacy and safety of granisetron-based therapy were non-inferior to those of palonosetron-based therapy. Taken together with treatment costs, granisetron monotherapy would be adequate to prevent CINV in patients with non-Hodgkin lymphoma receiving bendamustine-based chemotherapy.

    Purpose: This study evaluates outcomes and patterns of care among patients receiving radiation therapy (RT) for bone metastases at a high-volume academic institution. Methods and Materials: Records of all patients whose final RT course was for bone metastases from April 2007 to July 2012 were identified from electronic medical records. Chart review yielded demographic and clinical data. Rates of complicated versus uncomplicated bone metastases were not analyzed. Results: We identified 339 patients whose final RT course was for bone metastases. Of these, 52.2% were male; median age was 65 years old. The most common primary was non-small-cell lung cancer (29%). Most patients (83%) were prescribed ≤10 fractions; 8% received single-fraction RT. Most patients (52%) had a documented goals of care (GOC) discussion with their radiation oncologist; hospice referral rates were higher when patients had such discussions (66% with vs 50% without GOC discussion, P=.004). Median life expectancy after RT was 96 days. Median survival after RT was shorter based on inpatient as opposed to outpatient status at the time of consultation (35 vs 136 days, respectively, P<.001). Hospice referrals occurred for 56% of patients, with a median interval between completion of RT and hospice referral of 29 days and a median hospice stay of 22 days. Conclusions: These data document excellent adherence to American Society for Radiation Oncolology Choosing Wisely recommendation to avoid routinely using >10 fractions of palliative RT for bone metastasis. Nonetheless, single-fraction RT remains relatively uncommon. Participating in GOC discussions with a radiation oncologist is associated with higher rates of hospice referral. Inpatient status at consultation is associated with short survival.

    Liver transplantation is widely accepted as an effective therapy of hepatoma. Perioperative dynamic observation of coagulation function is important for graft-receivers. This study was to explore perioperative changes of coagulation functions in the local advanced liver cancer patients who received liver transplantation. Clinical data of 31 local advanced liver cancer patients, underwent liver transplantation from Sep. 2003 to Jan. 2007, were analyzed. Platelet (PLT) counting, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fib) and international normalized ratio (INR) before operation, at anhepatic phase and the first week after operation were analyzed to evaluate congulation function. The coagulation functions of most patients were normal before operation. The six parameters varied significantly at anhepatic phase and on most days of the first week after operation when compared with the preoperative levels (Pfunctions of local advanced liver cancer patients shift from hypocoagulatory to hypercoagulatory or normal in perioperative period, therefore, prevention of bleeding should be focused on at anhepatic phase and on 1-2 days after operation while prevention of thrombosis should be focused on after the first week after operation. The degree of liver cirrhosis and Child-Pugh level could help to evaluate postoperative coagulation disorder.

    Full Text Available Background. Globally, it is estimated that depressive features occur in 15 - 36% of people suffering from chronic diseases and 60% of people with HIV/AIDS. A high prevalence of mental disorders among HIV-infected individuals has been shown in South Africa and other parts of sub-Saharan Africa. Untreated depression leads to poor adherence to treatment and poor quality of life for patients with chronic diseases. Methods. Using the Zung self-rating scale, we screened for depressive features among adult patients receiving highly active antiretroviral therapy (HAART who attended primary healthcare facilities in the Rustenburg district of North West Province in South Africa during December 2009. Results. Among 117 participants, 81 (69.2 % had mild depressive features, 2 (1.7% had moderate depressive features, 1 (0.9 % had severe depressive features and 33 (28.2% did not have depressive features. Depressive features were more common in males (77.1% than in females (69.5%, and were most common in patients taking the combination of efavirenz, lamivudine and stavudine. Conclusion. Depressive features seem to be common among adult patients receiving HAART and attending primary healthcare facilities in the Rustenburg district.

    Full Text Available Abstract Background Lithium-induced thyroid abnormalities have been documented in many studies. They may occur despite normal plasma lithium levels. The objectives of this study were: 1 to determine possible relationship between lithium ratio, defined as erythrocyte lithium concentrations divided by plasma lithium concentrations, and thyroid abnormalities in bipolar patients receiving lithium and 2 to find other possible risk factors for developing thyroid abnormalities in the subjects. Methods Sixty-eight bipolar patients receiving lithium therapy were enrolled in a cross-sectional evaluation of thyroid function test and thyroid size. Patients were divided into two groups based on their thyroid function tests and thyroid sizes. Erythrocyte and plasma lithium concentrations were determined by atomic absorption spectrometry for each patient. Lithium ratio was then calculated. Results No significant differences were found between age, positive family history of affective disorder, plasma lithium concentration, erythrocyte lithium concentration, and lithium ratio comparing the two groups. Thyroid abnormalities was significantly higher in women than in men (p Conclusions Lithium ratio does not appear to have a predictive role for thyroidal side effects of lithium therapy. Female gender was the main risk factor. We suggest more frequent thyroid evaluation of bipolar women who are treated with lithium.

    Full Text Available Louise RoseLawrence S Bloomberg Faculty of Nursing, University of Toronto, Toronto, Ontario, CanadaAbstract: Patients requiring noninvasive and invasive ventilation frequently present to emergency departments, and may remain for prolonged periods due to constrained critical care services. Emergency clinicians often do not receive the same education on management of mechanical ventilation or have similar exposure to these patients as do their critical care colleagues. The aim of this review was to synthesize the evidence on management of patients requiring noninvasive and invasive ventilation in the emergency department including indications, clinical applications, monitoring priorities, and potential complications. Noninvasive ventilation is recommended for patients with acute exacerbation of chronic obstructive pulmonary disease or cardiogenic pulmonary edema. Less evidence supports its use in asthma and other causes of acute respiratory failure. Use of noninvasive ventilation in the prehospital setting is relatively new, and some evidence suggests benefit. Monitoring priorities for noninvasive ventilation include response to treatment, respiratory and hemodynamic stability, noninvasive ventilation tolerance, detection of noninvasive ventilation failure, and identification of air leaks around the interface. Application of injurious ventilation increases patient morbidity and mortality. Lung-protective ventilation with low tidal volumes based on determination of predicted body weight and control of plateau pressure has been shown to reduce mortality in patients with acute respiratory distress syndrome, and some evidence exists to suggest this strategy should be used in patients without lung injury. Monitoring of the invasively ventilated patient should focus on assessing response to mechanical ventilation and other interventions, and avoiding complications, such as ventilator-associated pneumonia. Several key aspects of management of noninvasive

    Background  Radiology is an interdisciplinary field dedicated to the diagnosis and treatment of numerous diseases and is involved in the development of multimodal treatment concepts. Method  Interdisciplinary case management, a broad spectrum of diagnostic imaging facilities and dedicated endovascular radiological treatment options are valuable tools that allow radiology to set up an interdisciplinary center for vascular anomalies. Results  Image-based diagnosis combined with endovascular treatment options is an essential tool for the treatment of patients with highly complex vascular diseases. These vascular anomalies can affect numerous parts of the body so that a multidisciplinary treatment approach is required for optimal patient care. Conclusion  This paper discusses the possibilities and challenges regarding effective and efficient patient management in connection with the formation of an interdisciplinary center for vascular anomalies with strengthening of the clinical role of radiologists. Key points   · Vascular anomalies, which include vascular tumors and malformations, are complex to diagnose and treat.. · There are far more patients with vascular anomalies requiring therapy than interdisciplinary centers for vascular anomalies - there is currently a shortage of dedicated interdisciplinary centers for vascular anomalies in Germany that can provide dedicated care for affected patients.. · Radiology includes a broad spectrum of diagnostic and minimally invasive therapeutic tools which allow the formation of an interdisciplinary center for vascular anomalies for effective, efficient and comprehensive patient management..

    To assess joint disease activity by ultrasound (US) in patients with rheumatoid arthritis (RA) initiating treatment with adalimumab (ADA) plus methotrexate (MTX). Data for this post hoc analysis originated from the MUSICA trial (ClinicalTrials.gov identifier: NCT01185288), which evaluated the efficacy of initiating ADA (40 mg every other week) plus 7.5 or 20 mg/week MTX in 309 patients with RA with an inadequate response to MTX. Synovial vascularization over 24 weeks was assessed bilaterally at metacarpophalangeal joint 2 (MCP2), MCP3, MCP5, metatarsophalangeal joint 5, and the wrists by power Doppler US (PDUS). A semiquantitative 4-grade scale was used. Disease activity was assessed using the Disease Activity Score in 28 joints using the C-reactive protein level (DAS28-CRP) and Simplified Disease Activity Index (SDAI). The correlation between continuous variables was assessed using Pearson's correlation coefficient. After 24 weeks of treatment with ADA plus MTX, rapid improvements in the mean synovial vascularity score were observed; the greatest improvements were in MCP2 (-0.5), MCP3 (-0.4), and the wrist (-0.4). At week 24, patients with the lowest DAS28-CRP ( 0.9). Synovial vascularity scores correlated poorly with DAS28, swollen joint count in 66 joints (SJC66), SJC28, tender joint count in 68 joints (TJC68), TJC
