This study aimed to identify caregiver burden and influencing factors on the burden in primary caregivers of peripheral blood stem cell transplantation patients within 2-12 months following transplant, indicating early recovery period after discharge. This descriptive cross sectional study was carried out at hematopoietic stem cell transplantation outpatient units of three university hospitals in Turkey. A total of 55 patient and caregiver dyads were recruited and interviewed. The data were collected using questionnaires developed by the researchers and caregiver burden was measured with the Zarit Burden Interview. The mean score of Zarit Burden Interview was 28.41 (SD = 13.90). Patients' symptoms including nausea and self depreciation feeling were related to greater caregiver burden. Self-depreciation was referred to feeling undervalued. The mean score of the tool was significantly higher in caregivers who have not been educated beyond primary school and also caregivers who had lower income. Caregivers who supported their patients to fulfill physical needs and who did not receive help for meeting patients' psychological needs had statistically more elevated levels of burden. Moreover, the extent of care giving activities undertaken was positively correlated with caregiver burden scores. While positive impact of the care giving process on family relations decreased caregiver burden; negative effect increased the burden. This study suggests that caregiver burden of primary caregivers caring for peripheral blood stem cell transplantation patients varies by education, income status, and the extent of care giving activities undertaken. Changes in family ties and relations due to care giving effected caregiver burden. Copyright © 2014 Elsevier Ltd. All rights reserved.

The aim of this study was to determine the associations between health locus of control (LoC), causal attributions and coping in tumour patients prior to autologous peripheral blood stem cell transplantation. Patients completed the Questionnaire of Health Related Control Expectancies, the Questionnaire of Personal Illness Causes (QPIC), and the Freiburg Questionnaire of Coping with Illness. A total of 126 patients (45% women; 54% suffering from a multiple myeloma, 29% from non-Hodgkin lymphomas, and 17% from other malignancies) participated in the study. Cluster analysis yielded four LoC clusters: 'fatalistic external', 'powerful others', 'yeah-sayer' and 'double external'. Self-blaming QPIC items were positively correlated with depressive coping, and 'fate or destiny' attributions with religious coping (P<0.001). The highest scores were found for 'active coping' in the LoC clusters 'powerful others' and 'yeah-sayer'. External LoC and an active coping style prevail before undergoing autologous peripheral blood stem cell transplantation, whereas the depressive coping is less frequent, associated with self-blaming causal attributions. Health beliefs include causal and control attributions, which can improve or impair the patient's adjustment. A mixture between internal and external attributions seems to be most adaptive.

The aim of this study was to explore the effect of electroacupuncture (EA) on immune function in patients undergoing supratentorial craniotomy. We also examined whether point specificity in EA was present. The study involved 29 patients undergoing craniotomy. The patients were divided into three groups: a control (C, n=10), an EA (A, n=9) and a sham acupoints group (S, n=10). Blood samples were collected at the following time points: before anesthesia (T0), 4 h after the induction of anesthesia (T1), 1 day post-surgery (T2) and 2 days post-surgery (T3) to determine the levels of tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), interleukin-10 (IL-10), immunoglobulin M (IgM), IgA and IgG. Data were analyzed using SPSS 13.0 software. When comparing the levels of cytokines following surgery, we observed that the peripheral blood IL-8 levels in groups A and S were increased significantly compared with those of group C at 1 and 2 days after surgery. When comparing immunoglobulin levels after surgery, we established that the peripheral blood IgA levels in group C had decreased significantly compared to those of group A and group S 4 h after induction of anesthesia and 1 day after surgery. However, there was no significant difference between group A and group S. Compared with simple general anesthesia, acupuncture combined with anesthesia partially reduces immune suppression in the perioperative periods under the same conditions as the simple general anesthesia. Point specificity in EA was not present. PMID:24137250

Reactive hyperemia is the compensatory increase in blood flow that occurs after a period of tissue ischemia, and this response is blunted in patients with cardiovascular risk factors. The predictive value of reactive hyperemia for cardiovascular events in patients with atherosclerosis and the relative importance of reactive hyperemia compared with other measures of vascular function have not been previously studied. We prospectively measured reactive hyperemia and brachial artery flow-mediated dilation by ultrasound in 267 patients with peripheral arterial disease referred for vascular surgery (age 66+/-11 years, 26% female). Median follow-up was 309 days (range 1 to 730 days). Fifty patients (19%) had an event, including cardiac death (15), myocardial infarction (18), unstable angina (8), congestive heart failure (6), and nonhemorrhagic stroke (3). Patients with an event were older and had lower hyperemic flow velocity (75+/-39 versus 95+/-50 cm/s, P=0.009). Patients with an event also had lower flow-mediated dilation (4.5+/-3.0 versus 6.9+/-4.6%, P<0.001), and when these 2 measures of vascular function were included in the same Cox proportional hazards model, lower hyperemic flow (OR 2.7, 95% CI 1.2 to 5.9, P=0.018) and lower flow-mediated dilation (OR 4.2, 95% CI: 1.8 to 9.8, P=0.001) both predicted cardiovascular events while adjusting for other risk factors. Thus, lower reactive hyperemia is associated with increased cardiovascular risk in patients with peripheral arterial disease. Furthermore, flow-mediated dilation and reactive hyperemia incrementally relate to cardiovascular risk, although impaired flow-mediated dilation was the stronger predictor in this population. These findings further support the clinical relevance of vascular function measured in the microvasculature and conduit arteries in the upper extremity.

The objective of this study was to investigate the incidence, risk factors, and clinical and prognostic characteristics of febrile infection that occurred during the neutropenic period in cancer patients who underwent autologous peripheral blood stem cell transplantation (APBSCT). Clinical data of all the APBSCT cases from 2007 to 2009 in Sun Yat-sen University Cancer Center were collected and retrospectively analyzed. Eighty-nine APBSCT subjects were investigated. Neutropenia usually occurred on the 4th day (range, 0-15) after transplantation and lasted 6 (range, 3-27) days. Febrile neutropenia occurred in 78.7% patients and lasted around 3 (range, 1-20) days and no infection-related deaths were observed. For febrile episodes, 12 patients (17.1%) were diagnosed as having microbiologically documented infections (MDI). Initial empirical antimicrobial therapy was given to all cases of post-APBSCT febrile neutropenia, of which 44 cases (62.9%) were effective. Febrile neutropenia occurred in 25/34 (73.5%) patients who were given antifungal drugs for prophylaxis. Neutropenic infection is still the major complication in APBSCT patients and duration of neutropenia is one of the major risk factors. Prophylactic administration of antifungal drugs seems to be invalid to reduce post-APBSCT infection. Sufficient doses of broad-spectrum antibiotics at the early stage lead to better results of initial antimicrobial treatment. Copyright © 2015 Elsevier Inc. All rights reserved.

Heel pressure ulcer is a major complication in elderly hospitalized patients. The association with peripheral arterial disease (PAD) which is also a frequent disease in this population is poorly known. The aim of this study was to assess the prevalence of PAD and critical limb ischemia (CLI) in patients with heel pressure ulcer. Patients referred to the vascular medicine department for heel pressure ulcer from October 2014 to June 2015 were included in the study. The assessment of peripheral arterial disease was made with the results of ankle brachial index and/or doppler ultra sound of lower limb arteries. Toe systolic pressure and transcutaneous pressure (TcPO2) were also recorded, and the diagnosis of critical limb ischemia was made according to the TASC 2 criteria. The population was composed with 42 patients (women 43%, men 57%). The mean age was 81±11 years. Heel pressures ulcers were diagnosed in the following situations: lower limb fracture (31%), acute medical illness (21%), multiple chronic conditions (28%) and critical care unit hospitalization (7%). A peripheral arterial disease was present in 31 patients (73%), and a critical limb ischemia in 7 patients. For 18 patients, PAD was not known in their past medical history, and this was the case of 5 patients among those with critical limb ischemia. A revascularization was performed in 12 patients, and 5 patients undergo a lower limb amputation. 12 patients were died at 3 months. PAD is frequent among patients with heel pressure ulcer, and is often unknown. The functional and vital prognostic are poor, and the results of our study emphasize the importance of screening PAD in the evaluation of heel pressure ulcer risk.

Disorders of mineral metabolism, including secondary hyperparathyroidism, are thought to contribute to extraskeletal (including vascular) calcification among patients with chronic kidney disease. It has been hypothesized that treatment with the calcimimetic agent cinacalcet might reduce the risk of death or nonfatal cardiovascular events in such patients. In this clinical trial, we randomly assigned 3883 patients with moderate-to-severe secondary hyperparathyroidism (median level of intact parathyroid hormone, 693 pg per milliliter [10th to 90th percentile, 363 to 1694]) who were undergoing hemodialysis to receive either cinacalcet or placebo. All patients were eligible to receive conventional therapy, including phosphate binders, vitamin D sterols, or both. The patients were followed for up to 64 months. The primary composite end point was the time until death, myocardial infarction, hospitalization for unstable angina, heart failure, or a peripheral vascular event. The primary analysis was performed on the basis of the intention-to-treat principle. The median duration of study-drug exposure was 21.2 months in the cinacalcet group, versus 17.5 months in the placebo group. The primary composite end point was reached in 938 of 1948 patients (48.2%) in the cinacalcet group and 952 of 1935 patients (49.2%) in the placebo group (relative hazard in the cinacalcet group vs. the placebo group, 0.93; 95% confidence interval, 0.85 to 1.02; P=0.11). Hypocalcemia and gastrointestinal adverse events were significantly more frequent in patients receiving cinacalcet. In an unadjusted intention-to-treat analysis, cinacalcet did not significantly reduce the risk of death or major cardiovascular events in patients with moderate-to-severe secondary hyperparathyroidism who were undergoing dialysis.

To evaluate if WT1 expression may predict relapse after allo-SCT, we analyzed WT1 levels on peripheral blood (PB) and bone marrow (BM) before and after allo-SCT in 24 AML patients with WT1 overexpression at diagnosis. Five copies of WT1/ABL × 104 from PB were identified as the threshold value that correlated with relapse after allo-SCT. The same correlation was not identified when WT1 expression was assessed from bone marrow (BM). Eight out of 11 (73%) patients with a pre-allo-SCT PB-WT1 ≥ 5 and 4/13 (31%) patients with a pre-allo-SCT PB-WT1 < 5 relapsed, respectively (P = 0.04). The incidence of relapse was higher in patients with PB-WT1 ≥ 5 measured after allo-SCT, at the 3rd (56% versus 38%; P = 0.43) and at the 6th month (71% versus 20%; P = 0.03). Patients with pretransplant PB-WT1 < 5 had significantly better 2-year OS and LFS than patients with a PB-WT1 ≥ 5 (81% versus 0% and 63% versus 20%) (P = 0.02). Our data suggest the usefulness of WT1 monitoring from PB to predict the relapse in allotransplanted AML patients and to modulate the intensity of conditioning and/or the posttransplant immunosuppression in an attempt to reduce the posttransplant relapse risk.

The clinical effect of bag-plasmapheresis was investigated in 60 patients with peripheral arterial occlusive disease stage II according to Fontaine. The initial number of patients was subdivided in three groups of 20 individuals using a randomised double-blind placebo-controlled design. Each patient gave 300 ml of blood twice a week for a 6 week duration. Blood plasma was separated in two groups and replaced with Hydroxyethyl-starch (200/0.5 10%) in group 1 and with Laevulose 5% in group 2. Patients in group 3 received their whole blood without any processing. All patients had to undergo a physical training of 45 minutes three times a week. The group who received Hydroxyethylstarch presented a 20% increase in walking distance whereas the increase in the Laevulose group was 5% and approximately 1% in the group receiving whole blood. The increase in walking distance in the Hydroxyethylstarch-group was significant on the 0.1%-level and significantly better than the improvement in walking distance of the other groups. Additionally in this group plasma viscosity showed a 3% decrease, erythrocyte aggregation was reduced by 10%. Results in the Laevulose group were only half as good as in the Hydroxyethylstarch group while parameters remained unchanged in the whole-blood-group. Bag plasmapheresis with Hydroxyethylstarch as substitute leads to an improvement in the walking capacity and blood fluidity thus offering a promising therapy for peripheral vascular occlusive disease.

INTRODUCTION: The present study examines cardiovascular risk factor profiles and 24-month mortality in patients with symptomatic peripheral arterial disease. DESIGN STUDY: Prospective observational study including 75 consecutive patients with PAD (67 ± 9.7 years of age; 52 men and 23 women) hospitalized for planned peripheral vascular reconstruction. Doppler echocardiograms were performed before surgery in 54 cases. Univariate analyses were performed using Student’s t-test or Fisher’s exact test. Survival analysis at 24-month follow-up was performed using the Cox regression model and Kaplan-Meier method including age and chronic use of aspirin as covariates. Survival curves were compared using the log-rank test. RESULTS: Hypertension and smoking were the most frequent risk factors (52 cases and 51 cases, respectively), followed by diabetes (32 cases). Undertreated dyslipidemia was found in 26 cases. Fasting glycine levels (131 ± 69.1 mg/dl) were elevated in 29 cases. Myocardial hypertrophy was found in 18 out of 54 patients. Thirty-four patients had been treated with aspirin. Overall mortality over 24 months was 24% and was associated with age (HR: 0.064; CI95: 0.014–0.115; p=0.013) and lack of use of aspirin, as no deaths occurred among those using this drug (p<0.001). No association was found between cardiovascular death (11 cases) and the other risk factors. CONCLUSION: There is a high prevalence of uncontrolled (treated or untreated) cardiovascular risk factors in patients undergoing planned peripheral vascular reconstruction, and chronic use of aspirin is associated with reduced all-cause mortality in these patients.

The symptom clusters in patients with ovarian cancer undergoing chemotherapy have not been well evaluated. We investigated the symptom clusters and effects of symptom clusters on the quality of life of patients with ovarian cancer. We recruited 210 ovarian cancer patients being treated with chemotherapy and used a descriptive cross-sectional study design to collect information on their symptoms. To determine inter-relationships among symptoms, a principal component analysis with varimax rotation was performed based on the patient's symptoms (fatigue, pain, sleep disturbance, chemotherapy-induced peripheral neuropathy, anxiety, depression, and sexual dysfunction). All patients had experienced at least two domains of concurrent symptoms, and there were two types of symptom clusters. The first symptom cluster consisted of anxiety, depression, fatigue, and sleep disturbance symptoms, while the second symptom cluster consisted of pain and chemotherapy-induced peripheral neuropathy symptoms. Our subgroup cluster analysis showed that ovarian cancer patients with higher-scoring symptoms had significantly poorer quality of life in both symptom cluster 1 and 2 subgroups, with subgroup-specific patterns. The symptom clusters were different depending on age, age at disease onset, disease duration, recurrence, and performance status of patients with ovarian cancer. In addition, ovarian cancer patients experienced different symptom clusters according to cancer stage. The current study demonstrated that there is a specific pattern of symptom clusters, and symptom clusters negatively influence the quality of life in patients with ovarian cancer. Identifying symptom clusters of ovarian cancer patients may have clinical implications in improving symptom management. Copyright © 2017 Elsevier Ltd. All rights reserved.

Objective To assess the frequency and reasons for return to the primary acute care service among leukemia patients undergoing inpatient rehabilitation. Design Retrospective study of all patients with leukemia, myelodysplastic syndrome, aplastic anemia, or myelofibrosis admitted to inpatient rehabilitation at a tertiary referral-based cancer center between January 1, 2005, and April 10, 2012. Items analyzed from patient records included return to the primary acute care service with demographic information, leukemia characteristics, medications, hospital admission characteristics, and laboratory values. Results 225 patients were admitted a total of 255 times. 93/255 (37%) of leukemia inpatient rehabilitation admissions returned to the primary acute care service. 18/93 (19%) and 42/93 (45%) of these patients died in the hospital and were discharged home respectively. Statistically significant factors (p<.05) associated with return to the primary acute care service include peripheral blast percentage and the presence of an antifungal agent on the day of inpatient rehabilitation transfer. Using an additional two factors (platelet count and the presence of an antiviral agent both with a p<.11), a Return To Primary (RTP) - Leukemia index was formulated. Conclusions Leukemia patients with the presence of circulating peripheral blasts and/or antifungal agent may be at increased risk of return to the primary acute care service. The RTP-Leukemia index should be tested in prospective studies to determine its usefulness. PMID:23117267

Patients with peripheral arterial disease (PAD) undergoing percutaneous coronary intervention (PCI) are at high risk for adverse cardiovascular events. Trends over time in outcomes with advances in PCI and medical therapy are unknown. We evaluated 866 patients with PAD in the National Heart, Lung, and Blood Institute (NHLBI) Dynamic Registry undergoing PCI according to treatment eras: the early bare metal stent (BMS) era (wave 1, 1997 to 1998, n = 180), the BMS era (waves 2 and 3, 1999 and 2001 to 2002, n = 339), and the drug-eluting stent (DES) era (waves 4 and 5, 2004 and 2006, n = 347). We compared in-hospital and 1-year outcomes by recruitment era. In-hospital coronary artery bypass graft surgery rates were significantly lower in the later eras (3.9%, 0.9%, and 0.6% for the early BMS, BMS, and DES eras, respectively, p for trend = 0.005), and an increasing percentage of patients were discharged on aspirin, β blockers, statins, and thienopyridines (p for trend <0.001 for all comparisons). Cumulative 1-year event rates in patients with PAD in the early BMS era, BMS era, and DES era for death were 13.7%, 10.5%, and 9.8% (p for trend = 0.21), those for myocardial infarction (MI) were 9.8%, 8.8%, and 10.0% (p for trend = 0.95), and those for repeat revascularization were 26.8%, 21.0%, and 17.2% (p for trend = 0.008). The 1-year adjusted hazard ratios of adverse events in patients with PAD using the early BMS era as the reference were 0.84 for death in the BMS era (95% confidence interval [CI] 0.46 to 1.55, p = 0.58) and 1.35 in the DES era (95% CI 0.71 to 2.56, p = 0.36), 0.89 for MI in the BMS era (95% CI 0.48 to 1.66, p = 0.72) and 1.02 in the DES era (95% CI 0.55 to 1.87, p = 0.95), and 0.63 for repeat revascularization in the BMS era (95% CI 0.41 to 0.97, p = 0.04) and 0.46 in the DES era (95% CI 0.29 to 0.73, p = 0.001). In conclusion, despite significant improvements in medical therapy and a decrease in repeat revascularization over time, patients with PAD

This pilot exploratory study aimed to describe the changes in nutritional status, body composition, quality of life (QoL), and physical activity levels (PAL) of cancer patients undergoing high-dose conditioning and autologous peripheral blood stem cell transplantation (PBSCT) at pre-admission, hospital discharge, and at 100 days post-transplantation, and to examine if changes in these parameters are interrelated. Twenty-four patients (56.2 ± 12.9 years; 7 females, 17 males) were recruited from an Australian transplant center. Assessment was prospectively conducted at pre-admission, hospital discharge, and 100 days post-transplantation using the scored patient-generated subjective global assessment, air displacement plethysmography, EORTC QLQ-C30 (version 3), and the international physical activity questionnaire. At discharge, nutritional status deteriorated (patient-generated subjective global assessment (PG-SGA) median, +8.0; interquartile range, 6.0-13.0; p < 0.001) and the number of malnourished patients increased (n = 8/23; p = 0.023). Patients experienced significant loss of lean body mass (LBM; -2.2 kg, CI 95% -3.0, -1.4; p < 0.001), and decrease in QoL (-10.6, CI 95% -24.1, 2.9; p = 0.117); the proportion of patients with high PAL decreased (p = 0.012). By 100 days post-transplantation, all patients were well-nourished; however, LBM remained lower -1.0 kg (CI 95% -1.9, -0.1; p = 0.028). Change in nutritional status (PG-SGA score) was associated with weight (r = -0.46; p = 0.039) and fat mass (r = -0.57; p = 0.013). Change in QoL was associated with nutritional reservoir (i.e., fat; r = 0.54; p = 0.024); QoL was consistently higher for patients with high PAL. High-dose conditioning and autologous PBSCT is associated with deterioration in nutritional status, QoL and PAL, with LBM remaining below baseline levels at 100 days post-transplantation.

The development of a standardised reporting set is important to ensure that research is directed towards the most important outcomes and that data is comparable. To ensure validity, the set must be agreed by a consensus of stakeholders including patients, healthcare professionals and lay representatives. There is currently no agreed core outcome set for patients undergoing major lower limb amputation for peripheral arterial disease (PAD) for either short- or medium-term research outcomes. By developing these sets we aim to rationalise future trial outcomes, facilitate meta-analysis and improve the quality and applicability of amputation research. We will undertake a comprehensive systematic review of studies of patients undergoing major lower limb amputation for PAD. Data regarding all primary and secondary outcomes reported in relevant studies will be extracted and summarised as outcome domains. We will then undertake focus groups with key stakeholders (patients, carers, health and social care workers) to collect qualitative data to identify the main short- and medium-term research outcomes for patients undergoing major lower limb amputation. Results of the systematic review and focus groups will be combined to create a comprehensive list of potential key outcomes. Stakeholders (patients, researchers and health and social care workers) will then be polled to determine which of the outcomes are considered to be important in a general context using a three-phase Delphi process. After preliminary analysis, results will be presented at a face-to-face meeting of key stakeholders for discussion and voting on the final set of core outcomes. This project is being run in parallel with a feasibility trial assessing perineural catheters in patients undergoing lower limb amputation (the PLACEMENT trial). Full ethical approval has been granted for the study (Wales REC 3 reference number 16/WA/0353). Core outcome sets will be developed for short- and medium-term outcomes of

We conducted a descriptive study to identify the symptoms, emotional status, and quality of life experienced by hospitalized ovarian cancer patients undergoing chemotherapy, and influencing the factors of symptom clusters on their quality of life. A total of 192 patients who had been diagnosed with ovarian cancer and received adjuvant chemotherapy after surgery more than once from 2 university hospitals with over 800 beds located in the Seoul and Gyeonggi areas of South Korea were included in this study. Using a structured questionnaire, the symptoms, emotional status, and quality of life by these patients were investigated from May 2012 to June 2013. We identified the following 7 symptom clusters among ovarian cancer patients undergoing chemotherapy: psychological distress, fatigue-pain, abdominal discomfort, flu-like symptoms, fluid accumulation, and peripheral neuropathy.

Impaired glucose regulation (IGR) is the prestate of diabetes; about 1/3 of IGR patients will develop to diabetes finally. In this study, we investigated the serum tumor necrosis factor-alpha (TNF- α ) and interleukin-6 (IL-6) levels in peripheral neuropathy impaired patients with impaired glucose regulation (IGR). A total of 70 IGR patients received the conventional nerve conduction test, including 30 patients with peripheral neuropathy (PN) and 40 patients without peripheral neuropathy (NPN). The other 40 healthy individuals were recruited as controls. The serum TNF- α and IL-6 in IGR patients were higher than in control group, and serum TNF- α and IL-6 levels in IGR-PN group were higher than in IGR-NPN group (27.7 ± 17.8 versus 13.1 ± 6.7 pg/mL and 18.1 ± 17.7 versus 6.4 ± 3.7 pg/mL, resp., both p < 0.05). Multifactors logistic regression analysis showed that TNF- α (OR = 0.893; p = 0.009) was an independent factor affecting whether IGR could combine with peripheral neuropathy. TNF- α and IL-6 could aggregate peripheral neuropathy in impaired glucose regulation patients; TNF- α might be independent risk factor for peripheral neuropathy in glucose regulation impaired patients.

Central venous access is often used during apheresis procedure in stem cell collection. The aim of the present study was to evaluate whether central or peripheral venous access has an effect on stem cell yield and the kinetics of the procedure and the product in patients undergoing ASCT after high dose therapy. A total of 327 patients were retrospectively reviewed. The use of peripheral venous access for stem cell yield was significantly more frequent in males compared to females (p = 0.005). Total volume of the product was significantly lower in central venous access group (p = 0.046). As being a less invasive procedure, peripheral venous access can be used for stem cell yield in eligible selected patients. Copyright © 2016 Elsevier Ltd. All rights reserved.

Clinical impact of exercise in patients with peripheral arterial disease.

2017-08-01

Increasing prevalence, high morbidity and mortality, and decreased health-related quality of life are hallmarks of peripheral arterial disease. About one-third of peripheral arterial disease patients have intermittent claudication with deleterious effects on everyday activities, such as walking. Exercise training improves peripheral arterial disease symptoms and is recommended as first line therapy for peripheral arterial disease. This review examines the effects of exercise training beyond improvements in walking distance, namely on vascular function, parameters of inflammation, activated hemostasis and oxidative stress, and quality of life. Exercise training not only increases walking distance and physiologic parameters in patients with peripheral arterial disease, but also improves the cardiovascular risk profile by helping patients achieve better control of hypertension, hyperglycemia, obesity and dyslipidemia, thus further reducing cardiovascular risk and the prevalence of coexistent atherosclerotic diseases. American guidelines suggest supervised exercise training, performed for a minimum of 30-45 min, at least three times per week, for at least 12 weeks. Walking is the most studied exercise modality and its efficacy in improving cardiovascular parameters in patients with peripheral arterial disease has been extensively proven. As studies have shown that supervised exercise training improves walking performance, cardiovascular parameters and quality of life in patients with peripheral arterial disease, it should be encouraged and more often prescribed.

Recent reports suggest increased frequency of peripheral neuropathy (PN) in Parkinson's disease (PD) patients on levodopa compared with age-matched controls particularly during continuous levodopa delivery by intestinal infusion (CLDII). The aim of this study is to compare frequency, clinical features, and outcome of PN in PD patients undergoing different therapeutic regimens. Three groups of consecutive PD patients, 50 on intestinal levodopa (CLDII), 50 on oral levodopa (O-LD) and 50 on other dopaminergic treatment (ODT), were enrolled in this study to assess frequency of PN using clinical and neurophysiological parameters. A biochemical study of all PN patients was performed. Frequency of PN of no evident cause was 28% in CLDII, 20% in O-LD, and 6% in ODT patients. Clinically, 71% of CLDII patients and all O-LD and ODT PN patients displayed a subacute sensory PN. In contrast, 29% of CLDII patients presented acute motor PN. Levodopa daily dose, vitamin B12 (VB12) and homocysteine (hcy) levels differed significantly in patients with PN compared to patients without PN. Our findings support the relationship between levodopa and PN and confirm that an imbalance in VB12/hcy may be a key pathogenic factor. We suggest two different, possibly overlapping mechanisms of PN in patients on CDLII: axonal degeneration due to vitamin deficiency and inflammatory damage. Whether inflammatory damage is triggered by vitamin deficiency and/or by modifications in the intestinal micro-environment should be further explored. Proper vitamin supplementation may prevent peripheral damage in most cases. Copyright © 2013 Elsevier Ltd. All rights reserved.

Intra and perioperative anticoagulation in patients with heparin induced thrombocytopenia (HIT), candidates for peripheral vascular surgery remains a challenge, as the best alternative to heparin has not yet been established. We evaluated the off-label use of fondaparinux in four patients with HIT, undergoing peripheral vascular surgery procedures. Four patients of whom 3 men of a mean age of 66 years, with proven heparin induced thrombocytopenia (HIT) underwent two axillo-femoral bypasses, one femoro-popliteal bypass and one resection of a splenic artery aneurysm under fondaparinux. No intra or perioperative bleeding or thrombosis of new onset was observed. In the absence of a valid alternative to heparin for intra and perioperative anticoagulation in HIT, several other anticoagulants can be used in an off-label setting. However, no general consensus exist on which should be the one of choice. In this small series fondaparinux appeared to be both safe and effective. These preliminary results seem to justify the off-label use of fondaparinux for intra and perioperative anticoagulation in patients with HIT, candidates for peripheral vascular surgery interventions.

This study sought to evaluate the effect of age on procedure type, periprocedural management, and in-hospital outcomes of patients undergoing lower-extremity (LE) peripheral vascular intervention (PVI). Surgical therapy of peripheral arterial disease is associated with significant morbidity and mortality in the elderly. There are limited data related to the influence of advanced age on the outcome of patients undergoing percutaneous LE PVI. Clinical presentation, comorbidities, and in-hospital outcomes of patients undergoing LE PVI in a multicenter, multidisciplinary registry were compared between 3 age groups: < 70 years, between 70 and 80 years, and ≥ 80 years (elderly group). In our cohort, 7,769 patients underwent LE PVI. The elderly patients were more likely to be female and to have a greater burden of comorbidities. Procedural success was lower in the elderly group (74.2% for age ≥ 80 years vs. 78% for age 70 to < 80 years and 81.4% in patients age < 70 years, respectively; p < 0.0001). Unadjusted rates of procedure-related vascular access complications, post-procedure transfusion, contrast-induced nephropathy, amputation, and major adverse cardiac events were higher in elderly patients. After adjustment for baseline covariates, the elderly patients were more likely to experience vascular access complications; however, advanced age was not found to be associated with major adverse cardiac events, transfusion, contrast-induced nephropathy, or amputation. Contemporary PVI can be performed in elderly patients with high procedural and technical success with low rates of periprocedural complications including mortality. These findings may support the notion of using PVI as a preferred revascularization strategy in the treatment of severe peripheral arterial disease in the elderly population.

We sought to develop a predictive model based exclusively on preoperative factors to identify patients at risk for PrlICULOS following coronary artery bypass grafting (CABG). Retrospective analysis was performed on patients undergoing isolated CABG at a single center between June 1998 and December 2002. PrlICULOS was defined as initial admission to ICU exceeding 72 h. A parsimonious risk-predictive model was constructed on the basis of preoperative factors, with subsequent internal validation. Of 3483 patients undergoing isolated CABG between June 1998 and December 2002, 411 (11.8%) experienced PrlICULOS. Overall in-hospital mortality was higher among these patients (14.4% vs. 1.2%, Pperipheral vascular disease, chronic obstructive pulmonary disease, ejection fraction <40%, previous CABG, triple-vessel and/or left main disease, NYHA class IV symptoms and urgent or emergent status. Subsequent validation of this model demonstrated a c-statistic of 78%. An internally-validated, risk predictive model of PrlICULOS in patients undergoing CABG was constructed. Based on preoperative clinical factors, a scorecard was developed allowing identification of these patients prior to surgery and allowing for strategies aimed at optimizing hospital resources.

Radiographic contrast administration is a major cause of acute kidney injury (AKI), worldwide. Currently, contrast induced acute kidney injury (CI-AKI) is the third leading cause of hospital acquired renal failure in the United States. Over 50% of these cases are the result of contrast exposure during cardiac catheterization. The predictive risk factors for and clinical impact of AKI following coronary procedures have been extensively studied and documented in the literature. Similar data, however, are lacking for AKI following angiography or endovascular interventions for lower extremity peripheral artery disease (PAD). The present review examined the published data available for AKI in patients undergoing peripheral procedures using MEDLINE searches. Specific data on number of peripheral cases, subject characteristics, hydration strategies, and AKI incidence rates was recorded. The systematic review resulted in 50 potentially relevant studies and ultimately 15 studies were selected for detailed analysis that included AKI incidence data on patients undergoing peripheral angiography or interventions. The summated studies included 11,311 patients and 10,316 peripheral procedures. The median incidence of AKI in the studies was 10%. The retrieved publications demonstrated significant variations in patient risk factors, definitions of AKI, and specificity of description of endovascular therapies. The incidence, risk factors, and outcomes related to AKI in the context of peripheral angiography or endovascular therapy remain poorly described in the literature and warrant further study in a prospective, systematic fashion. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

The effect of perioperative beta-blockade on the pulmonary function of patients undergoing major arterial surgery.

2006-09-01

Concern about the potential detrimental side-effects of beta-blockade on pulmonary function often dissuades against their perioperative use in patients undergoing major arterial surgery (especially in those with chronic obstructive pulmonary disease (COPD)). In this study we aimed to establish prospectively the clinical relevance of these concerns. After ethics committee approval and individual informed consent, the pulmonary function of twenty patients (mean age 68.7 years (range 43-82), 11 males) scheduled to undergo non-emergency major vascular surgery was studied by recording symptoms and spirometry before and after institution of effective beta-blockade. Fifteen patients (75%) had significant smoking histories (mean pack years/patient=50), while 12 (60%) had COPD. All patients tolerated effective beta-blockade satisfactorily without developing either subjective deterioration in symptoms or significant change on spirometry. The mean change in FEV1 following adequate beta-blockade was 0.05+/-0.24 liters (95% CI -0.06 to +1.61), p=0.35, giving a mean percentage change of 3.18%+/-11.66 (95% CI -2.26 to 8.62). Previously held concerns about worsening pulmonary function through the short-term use of beta-blockers should not dissuade their perioperative usage in patients with peripheral vascular disease. Furthermore, the accuracy of pulmonary function tests in preoperative assessment and risk stratification also appears unaffected by this therapy.

Given its practicality, the internet is a primary resource for patients afflicted with diseases like peripheral neuropathy. Therefore, it is important that the readily available online resources on peripheral neuropathy are tailored to the general public, particularly concerning readability. Patient education resources were downloaded from the US National Library of Medicine, Mayo Clinic, National Institute of Neurological Disorders and Stroke, Neuropathy.org, GBS/CIDP Foundation International, Hereditary Neuropathy Foundation, Charcot-Marie-Tooth Association, Foundation for Peripheral Neuropathy, and Neuropathy Action Foundation websites. All patient education material related to peripheral neuropathy was evaluated for its level of readability using the Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level. The FRE scores averaged 43.4 with only the US National Library of Medicine scoring above 60 (76.5). The Flesch-Kincaid Grade Level scores averaged 11.0. All scores were above a seventh-grade level except the US National Library of Medicine, which had a score of a fifth-grade reading level. Most Americans may not fully benefit from patient education resources concerning peripheral neuropathy education on many of the websites. Only the US National Library of Medicine, which is written at a fifth-grade level, is likely to benefit the average American. © 2013 Peripheral Nerve Society.

2016-06-01

To assess the bleeding risk profile using the HAS-BLED score in patients with symptomatic peripheral artery disease (PAD). A post hoc analysis was performed using data from a series of 115 consecutive patients (mean age 72.4±11.4 years; 68 men) with symptomatic PAD undergoing endovascular revascularization. The endpoint of the study was to assess bleeding risk using the 9-point HAS-BLED score, which was previously validated in cohorts of patients with and without atrial fibrillation. For the purpose of this study, the low (0-1), intermediate (2), and high-risk (≥3) scores were stratified as low/intermediate risk (HAS-BLED <3) vs high risk (HAS-BLED ≥3). The mean HAS-BLED score was 2.76±1.16; 64 (56%) patients had a HAS-BLED score ≥3.0. Patients with PAD Rutherford category 5/6 ischemia had an even higher mean HAS-BLED score (3.20±1.12). Logistic regression analysis revealed aortoiliac or femoropopliteal segment involvement, chronic kidney disease, as well as Rutherford category 5/6, to be independent risk factors associated with a HAS-BLED score ≥3. Patients with PAD, especially those presenting with Rutherford category 5/6 ischemic symptoms, have high HAS-BLED scores, suggesting increased risk for major bleeding. Prospective clinical validation of the HAS-BLED score in patients with PAD may help with the risk-benefit assessment when prescribing antithrombotic therapy. © The Author(s) 2016.

Objectives This study aimed to review general anaesthesia protocols for patients undergoing electroconvulsive therapy (ECT) at a tertiary care hospital in Oman, particularly with regards to clinical profile, potential drug interactions and patient outcomes. Methods This retrospective study took place at the Sultan Qaboos University Hospital (SQUH), Muscat, Oman. The electronic medical records of patients undergoing ECT at SQUH between January 2010 and December 2014 were reviewed for demographic characteristics and therapy details. Results A total of 504 modified ECT sessions were performed on 57 patients during the study period. All of the patients underwent a uniform general anaesthetic regimen consisting of propofol and succinylcholine; however, they received different doses between sessions, as determined by the treating anaesthesiologist. Variations in drug doses between sessions in the same patient could not be attributed to any particular factor. Self-limiting tachycardia and hypertension were periprocedural complications noted among all patients. One patient developed aspiration pneumonitis (1.8%). Conclusion All patients undergoing ECT received a general anaesthetic regimen including propofol and succinylcholine. However, the interplay of anaesthetic drugs with ECT efficacy could not be established due to a lack of comprehensive data, particularly with respect to seizure duration. In addition, the impact of concurrent antipsychotic therapy on anaesthetic dose and subsequent complications could not be determined. PMID:28417028

The objective was to determine the prevalence and clinical determinants of renal artery stenosis (RAS) in patients undergoing digital subtraction angiography (DSA) for the assessment of peripheral artery disease (PAD), and to evaluate its prognostic significance. All DSAs performed from January 2000 to January 2006 were retrospectively reviewed for assessment of PAD in patients naive for any prior revascularisation of lower-limb arteries. All DSA studies were read by two senior physicians blinded to outcome, and consensus was reached in cases of disagreement. RAS was defined as the presence of ≥50% stenosis in either renal artery. Patients' electronic medical files were systematically reviewed and follow-up was completed by contact with family physicians until January 2014. The primary outcome was composite, including death, peripheral revascularisation, or any limb amputation. Secondary outcomes were all-cause mortality, and another composite, including death and non-fatal myocardial infarction or stroke or coronary or carotid revascularisation. In total, 400 consecutive patients having a first DSA of lower extremities, two thirds of whom were for critical limb ischaemia, were studied. Thirteen patients were excluded owing to poor renal artery imaging. RAS was detected in 57 patients (14%). Only two factors were independently and significantly associated with RAS in multivariate analysis: diffuse PAD (involving both proximal and distal segments [odds ratio {OR} 3.50, 95% confidence interval {CI} 1.16-10.54; p = .026]) and decreased glomerular filtration rate (OR 0.55 per 30 mL/minute/1.73 m 2 , 95% CI 0.41-0.75; p < .001). During follow-up (mean ± SD 62 ± 47 months), 25% experienced limb amputation and 54% died. In multivariate analysis, no significant association was found between RAS and primary outcome (hazard ratio 0.80; 95% CI 0.57-1.10). No significant association was found with secondary outcomes. Incidental RAS is frequent (14%) among patients

This study was designed to show, in certain patients, that colonic epithelial cells can be present in peripheral blood while absent in portal venous blood. The circulating colorectal epithelial cells were detected by a reverse transcriptase-polymerase chain reaction assay, which involved amplifying guanylyl cyclase C transcripts. Portal venous and peripheral blood samples were obtained at intervals from 58 patients undergoing colorectal cancer surgery. Circulating colonic epithelial cells were more frequently detected in portal venous blood than in peripheral blood only before mobilization of the tumor-bearing colon segment in patients with tumors of Stage B. In five other patients, before mobilization of their tumor-bearing colon segments, and in another three patients, during the mobilization, colorectal epithelial cells were detected in peripheral blood but not in portal venous blood. These eight patients had Stage C or D tumors. In 8 of 58 patients, colorectal epithelial cells were detected in peripheral but not in portal venous blood. Metastatic deposits in lymphatic vessels or liver might be the source of these cells.

Progressive external ophthalmoplegia is a common clinical feature in mitochondrial disease caused by nuclear DNA defects and single, large-scale mitochondrial DNA deletions and is less frequently associated with point mutations of mitochondrial DNA. Peripheral neuropathy is also a frequent manifestation of mitochondrial disease, although its prevalence and characteristics varies considerably among the different syndromes and genetic aetiologies. Based on clinical observations, we systematically investigated whether the presence of peripheral neuropathy could predict the underlying genetic defect in patients with progressive external ophthalmoplegia. We analysed detailed demographic, clinical and neurophysiological data from 116 patients with genetically-defined mitochondrial disease and progressive external ophthalmoplegia. Seventy-eight patients (67%) had a single mitochondrial DNA deletion, 12 (10%) had a point mutation of mitochondrial DNA and 26 (22%) had mutations in either POLG, C10orf2 or RRM2B, or had multiple mitochondrial DNA deletions in muscle without an identified nuclear gene defect. Seventy-seven patients had neurophysiological studies; of these, 16 patients (21%) had a large-fibre peripheral neuropathy. The prevalence of peripheral neuropathy was significantly lower in patients with a single mitochondrial DNA deletion (2%) as compared to those with a point mutation of mitochondrial DNA or with a nuclear DNA defect (44% and 52%, respectively; P < 0.001). Univariate analyses revealed significant differences in the distribution of other clinical features between genotypes, including age at disease onset, gender, family history, progressive external ophthalmoplegia at clinical presentation, hearing loss, pigmentary retinopathy and extrapyramidal features. However, binomial logistic regression analysis identified peripheral neuropathy as the only independent predictor associated with a nuclear DNA defect (P = 0.002; odds ratio 8.43, 95% confidence

To characterize the profile and speech characteristics of patients undergoing primary palatoplasty in a Brazilian university hospital, considering the time of intervention (early, before two years of age; late, after two years of age). Participants were 97 patients of both genders with cleft palate and/or cleft and lip palate, assigned to the Speech-language Pathology Department, who had been submitted to primary palatoplasty and presented no prior history of speech-language therapy. Patients were divided into two groups: early intervention group (EIG) - 43 patients undergoing primary palatoplasty before 2 years of age and late intervention group (LIG) - 54 patients undergoing primary palatoplasty after 2 years of age. All patients underwent speech-language pathology assessment. The following parameters were assessed: resonance classification, presence of nasal turbulence, presence of weak intraoral air pressure, presence of audible nasal air emission, speech understandability, and compensatory articulation disorder (CAD). At statistical significance level of 5% (p≤0.05), no significant difference was observed between the groups in the following parameters: resonance classification (p=0.067); level of hypernasality (p=0.113), presence of nasal turbulence (p=0.179); presence of weak intraoral air pressure (p=0.152); presence of nasal air emission (p=0.369), and speech understandability (p=0.113). The groups differed with respect to presence of compensatory articulation disorders (p=0.020), with the LIG presenting higher occurrence of altered phonemes. It was possible to assess the general profile and speech characteristics of the study participants. Patients submitted to early primary palatoplasty present better speech profile.

The ventilated patient undergoing hydrotherapy: a case study.

2003-08-01

The ascending peripheral neuropathy and paralysis that result from Guillain-Barre Syndrome's (GBS) demyelination of peripheral nerves is a challenge to health professionals; the patient requires support during the acute disease process and during the remyelination recovery period, often lasting months to years. The staff of a major metropolitan teaching hospital's critical care unit (CCU) and physiotherapy departments developed a hydrotherapy treatment programme for a ventilated patient with GBS. Through careful planning and appropriate preparation, it was found that hydrotherapy could successfully and safely be incorporated into a patient's treatment regimen. The benefits included improved range of movement due to the supportive nature of water, anecdotal increased strength, size and movement of remyelinating muscles and a psychological improvement. Although this patient has not recovered from GBS to be independent, hydrotherapy was a valuable part of the treatment regimen and it could be suggested the increase muscle strength lead to improved respiratory function and enabled weaning from ventilation, reducing intensive care length of stay and cost.

Little is known about acute peripheral arterial thrombosis in patients with concomitant cancer. Small studies suggest that revascularization in this patient group is associated with thrombosis and increased risk of amputation and death. We investigated the frequency of cancer in patients operated on for acute peripheral arterial thrombosis and the long-term risk of amputation, mortality, myocardial infarction, and stroke in a national cohort. This was a prospective case/noncase study comprising all Danish citizens undergoing vascular surgery for acute arterial thrombosis from 1986 to 2012 with up to 26 years of follow-up. A total of 7840 patients were treated surgically for acute arterial thrombosis; 2384 (30.4%) were previously diagnosed with cancer or developed cancer during the observation period. Risk of amputation was not significantly different in patients with or without cancer, except in patients with cancer diagnosed <24 months before acute limb ischemia (hazard ratio, 2.0). Mortality was significantly greater in all patients having or developing cancer within 24 months after surgery (hazard ratio, 1.2-2.2). The frequencies of myocardial infarction and stroke were similar to those among patients without cancer. One of five patients operated on for acute limb ischemia has a diagnosis of cancer, and a further 3.4% will develop cancer within 24 months. The data further show that patients with acute limb ischemia and concomitant cancer can be successfully revascularized and that the majority of these patients preserve their limb. Cancer should therefore not contravene interventional treatment. Copyright © 2015 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.

Coagulation management in patients undergoing neurosurgical procedures.

2017-10-01

Management of coagulation in neurosurgical procedures is challenging. In this contest, it is imperative to avoid further intracranial bleeding. Perioperative bleeding can be associated with a number of factors, including anticoagulant drugs and coagulation status but is also linked to the characteristic and the site of the intracranial disorder. The aim of this review will be to focus primarily on the new evidence regarding the management of coagulation in patients undergoing craniotomy for neurosurgical procedures. Antihemostatic and anticoagulant drugs have shown to be associated with perioperative bleeding. On the other hand, an increased risk of venous thromboembolism and hypercoagulative state after elective and emergency neurosurgery, in particular after brain tumor surgery, has been described in several patients. To balance the risk between thrombosis and bleeding, it is important to be familiar with the perioperative changes in coagulation and with the recent management guidelines for anticoagulated patients undergoing neurosurgical procedures, in particular for those taking new direct anticoagulants. We have considered the current clinical trials and literature regarding both safety and efficacy of deep venous thrombosis prophylaxis in the neurosurgical population. These were mainly trials concerning both elective surgical and intensive care patients with a poor grade intracranial bleed or multiple traumas with an associated severe traumatic brain injury (TBI). Coagulation management remains a major issue in patients undergoing neurosurgical procedures. However, in this field of research, literature quality is poor and further studies are necessary to identify the best strategies to minimize risks in this group of patients.

OBJECTIVE The purpose of this study was to investigate the incidence of seizures during the intraoperative monitoring of motor evoked potentials (MEPs) elicited by electrical brain stimulation in a wide spectrum of surgeries such as those of the orthopedic spine, spinal cord, and peripheral nerves, interventional radiology procedures, and craniotomies for supra- and infratentorial tumors and vascular lesions. METHODS The authors retrospectively analyzed data from 4179 consecutive patients who underwent surgery or an interventional radiology procedure with MEP monitoring. RESULTS Of 4179 patients, only 32 (0.8%) had 1 or more intraoperative seizures. The incidence of seizures in cranial procedures, including craniotomies and interventional neuroradiology, was 1.8%. In craniotomies in which transcranial electrical stimulation (TES) was applied to elicit MEPs, the incidence of seizures was 0.7% (6/850). When direct cortical stimulation was additionally applied, the incidence of seizures increased to 5.4% (23/422). Patients undergoing craniotomies for the excision of extraaxial brain tumors, particularly meningiomas (15 patients), exhibited the highest risk of developing an intraoperative seizure (16 patients). The incidence of seizures in orthopedic spine surgeries was 0.2% (3/1664). None of the patients who underwent surgery for conditions of the spinal cord, neck, or peripheral nerves or who underwent cranial or noncranial interventional radiology procedures had intraoperative seizures elicited by TES during MEP monitoring. CONCLUSIONS In this largest such study to date, the authors report the incidence of intraoperative seizures in patients who underwent MEP monitoring during a wide spectrum of surgeries such as those of the orthopedic spine, spinal cord, and peripheral nerves, interventional radiology procedures, and craniotomies for supra- and infratentorial tumors and vascular lesions.

This study sought to evaluate the impact of an inter-hospital transfer strategy on treatment times and in-hospital and 1 year cardiac mortality of patients with ST-segment elevation acute myocardial infarction (STEMI) undergoing primary percutaneous intervention (p-PCI) in the Italian region of Emilia-Romagna, where an efficient region-wide system for reperfusion has been established. 3296 patients with STEMI, undergoing on-site p-PCI (2444 patients) (OS group) or p-PCI after inter-hospital transfer (852 patients) (T group) between 1 January 2004 and 30 June 2006 in the Italian region of Emilia-Romagna, were considered. During the study period, the number of patients undergoing p-PCI increased both for patients admitted to interventional centres and for those admitted to peripheral hospitals. At the same time, the proportion of patients with STEMI initially admitted to peripheral hospitals and not transferred and the door-to-balloon time delays of transfer patients decreased. In spite of longer door-to-balloon delay in the transfer group [112 min (86-147) vs. 71 min (46-104)], in-hospital cardiac mortality (OS 7.0 vs. T 5.4%, P = 0.10) did not significantly differ between the two groups. After multivariable adjustment, the transfer strategy was not associated with increased risk of in-hospital [odds ratio 0.956; 95% confidence interval (CI) 0.633-1.442] and 1 year (hazard ratio 0.817; 95% CI 0.617-1.085) cardiac mortality. This study, concerning an established STEMI regional network, suggests that a strategy of inter-hospital transfer for p-PCI, when supported by an organized system of care, may be applied with rapid reperfusion times and favourable short- and long-term clinical outcomes.

Progressive external ophthalmoplegia is a common clinical feature in mitochondrial disease caused by nuclear DNA defects and single, large-scale mitochondrial DNA deletions and is less frequently associated with point mutations of mitochondrial DNA. Peripheral neuropathy is also a frequent manifestation of mitochondrial disease, although its prevalence and characteristics varies considerably among the different syndromes and genetic aetiologies. Based on clinical observations, we systematically investigated whether the presence of peripheral neuropathy could predict the underlying genetic defect in patients with progressive external ophthalmoplegia. We analysed detailed demographic, clinical and neurophysiological data from 116 patients with genetically-defined mitochondrial disease and progressive external ophthalmoplegia. Seventy-eight patients (67%) had a single mitochondrial DNA deletion, 12 (10%) had a point mutation of mitochondrial DNA and 26 (22%) had mutations in either POLG, C10orf2 or RRM2B, or had multiple mitochondrial DNA deletions in muscle without an identified nuclear gene defect. Seventy-seven patients had neurophysiological studies; of these, 16 patients (21%) had a large-fibre peripheral neuropathy. The prevalence of peripheral neuropathy was significantly lower in patients with a single mitochondrial DNA deletion (2%) as compared to those with a point mutation of mitochondrial DNA or with a nuclear DNA defect (44% and 52%, respectively; P<0.001). Univariate analyses revealed significant differences in the distribution of other clinical features between genotypes, including age at disease onset, gender, family history, progressive external ophthalmoplegia at clinical presentation, hearing loss, pigmentary retinopathy and extrapyramidal features. However, binomial logistic regression analysis identified peripheral neuropathy as the only independent predictor associated with a nuclear DNA defect (P=0.002; odds ratio 8.43, 95% confidence interval 2

To evaluate the efficacy and safety of peripheral vitrectomy under air infusion in comparison with fluid infusion in patients undergoing 23-gauge pars plana vitrectomy for primary rhegmatogenous retinal detachment. A total of 80 eyes of 80 patients with primary rhegmatogenous retinal detachment were enrolled into the study. Forty cases underwent peripheral vitrectomy under air infusion (air group), and a control group of equal number underwent peripheral vitrectomy under fluid infusion (fluid group). Peripheral iatrogenic retinal breaks during peripheral vitrectomy, postoperative visual acuities, and retinal redetachment rates were compared. The number of eyes with peripheral iatrogenic retinal breaks in air group during peripheral vitrectomy was statistically comparable with that in fluid group (1/40 and 4/40, 2.5% and 10%, respectively; P = 0.16). Scleral depression was necessitated in 7 of 40 cases (17.5%) during the operation in the air group. There were no statistically significant differences between the groups in means of postoperative visual acuity and retinal redetachment (P = 0.18 and P = 1.0, respectively). Peripheral vitrectomy under air infusion for primary rhegmatogenous retinal detachment revealed comparable results with fluid infusion in terms of intraoperative and postoperative complications and surgical outcomes.

Antithrombotic agents are used increasingly in Asia. The management of patients on antithrombotics undergoing elective or emergency endoscopy has become an increasing clinical challenge for gastroenterologists. Current practice guidelines have been developed by societies from western countries. On the other hand, these guidelines cannot meet the specific needs of the Asian Pacific region, raising the need for separate guidelines in Asia. This review compares the recommendations of previous guidelines with the most recently published Asian guidelines regarding the management of patients on antithrombotic agents undergoing elective and emergency endoscopy.

The aim of the present study was to evaluate whether elevated cardiac troponin T (cTnT) was independently associated with an increased all-cause mortality or risk of cardiovascular events and amputation among patients with peripheral arterial disease (PAD). PAD patients often have impaired renal function, and the blood concentration of cardiac troponin often increases with declining glomerular filtration rate. The cohort consisted of 1,041 consecutive PAD patients (653 males, 388 females, age 70.7 ± 10.8 years, Rutherford stages 2 to 5) undergoing endovascular peripheral revascularization. At baseline, measurable cTnT levels (≥0.01 ng/ml) were detected in 21.3% of individuals. Compared with patients who had undetectable cTnT levels, those with cTnT levels ≥0.01 ng/ml had higher rates for mortality (31.7% vs. 3.9%, respectively; p < 0.001), myocardial infarction (4.1% vs. 1.1%, respectively; p = 0.003), and amputation (10.1% vs. 2.4%, respectively; p < 0.001) during a 1-year follow-up. In adjusted Cox regression models, cTnT levels ≥0.01 ng/ml were associated with increased total mortality (hazard ratio [HR]: 8.14; 95% confidence interval [CI]: 3.77 to 17.6; p < 0.001) and amputation rates (HR: 3.71; 95% CI: 1.33 to 10.3; p = 0.012). cTnT is frequently elevated in PAD patients and is associated with higher event rates in terms of total mortality and amputation. Even small cTnT elevations predict a markedly increased risk that is independent of an impaired renal function.

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 <70 years (prevalence ratio [PR] 2.42), male gender (PR 1.03), chronic obstructive pulmonary disease (PR 1.35), absence of prior cardiovascular procedures (PR 1.15), poor medication usage (PR 1.10), preoperative ankle-brachial index (ABI) <0.9 (PR 1.19), and supra-inguinal disease (PR 1.14). Invasiveness of treatment (PVI versus bypass procedures) was not significantly associated with 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

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

Innovations in minimally invasive surgery have led to more procedures being performed in the interventional radiology suite. It, therefore, is essential that nurses in radiology departments be competent to care for all types of patients. Use of nursing classification systems can improve care by providing standardized language for documentation. We conducted a project that involved 25 patients undergoing interventional radiology procedures between August and October 2006 in São Paulo, Brazil, to identify the most frequent North American Nursing Diagnosis Association (NANDA) nursing diagnoses used and then compared the NANDA diagnoses to Perioperative Nursing Data Set diagnoses. The most frequent nursing diagnoses in the participants were anxiety, chronic pain, inefficient tissue perfusion-peripheral, deficient knowledge, and risk for falls. These results are similar to diagnoses that have been reported in outpatient centers. The NANDA and Perioperative Nursing Data Set diagnoses were found to be similar. Copyright 2010 AORN, Inc.

Ultrasound-Guided Cryoanalgesia of Peripheral Nerve Lesions.

PubMed

Djebbar, Sahlya; Rossi, Ignacio M; Adler, Ronald S

2016-11-01

The real-time nature of ultrasound makes it ideally suited to provide guidance for a variety of musculoskeletal interventional procedures involving peripheral nerves. Continuous observation of the needle ensures proper placement and allows continuous monitoring when performing localized ablative therapy and therefore more accurate positioning of a cryoprobe, use of smaller needles, as well as access to small structures. We describe our experience performing cryoablative procedures. Patients undergoing cryoneurolysis have largely reported varying degrees of long-term pain relief and improvement in function; no serious complications have yet been identified. Ultrasound-guided cryoneurolysis can provide a useful, safe alternative to other ablative techniques to achieve long-term analgesia from painful peripheral nerve lesions.

Recent studies have shown a high prevalence of hypovitaminosis D, defined as a serum 25-hydroxyvitamin D level less than 30 ng/ml, in both healthy populations and patients with chronic kidney disease. Patients undergoing kidney transplant are at an increased risk of skin cancer and are advised to avoid sunlight exposure. Therefore, these patients might share two major risk factors for hypovitaminosis D: chronic kidney disease and low sunlight exposure. This paper describes the prevalence and clinical characteristics of hypovitaminosis D among patients undergoing kidney transplant. We evaluated 25-hydroxyvitamin D serum levels in a representative sample of patients undergoing kidney transplant. We sought to determine the prevalence of hypovitaminosis D, compare these patients with a control group, and identify factors associated with hypovitaminosis D (e.g., sunlight exposure and dietary habits). Hypovitaminosis D was found in 79% of patients undergoing kidney transplant, and the major associated factor was low sunlight exposure. These patients had higher creatinine and intact parathyroid hormone serum levels, with 25-hydroxyvitamin D being inversely correlated with intact parathyroid hormone serum levels. Compared with the control group, patients undergoing kidney transplant presented a higher prevalence of 25-hydroxyvitamin D deficiency and lower serum calcium, phosphate and albumin but higher creatinine and intact parathyroid hormone levels. Our results confirmed the high prevalence of hypovitaminosis D in patients undergoing kidney transplant. Therapeutic strategies such as moderate sunlight exposure and vitamin D supplementation should be seriously considered for this population.

As bariatric surgery rates continue to climb, anaemia will become an increasing concern. We assessed the prevalence of anaemia and length of hospital stay in patients undergoing bariatric surgery. Prospective data (anaemia [haemoglobin <12 g/dL], haematinics and length of hospital stay) was analysed on 400 hundred patients undergoing elective laparoscopic bariatric surgery. Results from a prospective database of 1530 patients undergoing elective general surgery were used as a baseline. Fifty-seven patients (14%) were anaemic pre-operatively, of which 98% were females. Median MCV (fL) and overall median ferritin (μg/L) was lower in anaemic patients (83 vs. 86, p=0.001) and (28 vs. 61, p<0.0001) respectively. In the elective general surgery patients, prevalence of anaemia was similar (14% vs. 16%) but absolute iron deficiency was more common in those undergoing bariatric surgery; microcytosis p<0.0001, ferritin <30 p<0.0001. Mean length of stay (days) was increased in the anaemic compared to in the non-anaemic group (2.7 vs. 1.9) and patients who were anaemic immediately post-operatively, also had an increased length of stay (2.7 vs. 1.9), p<0.05. Absolute iron deficiency was more common in patients undergoing bariatric surgery. In bariatric patients with anaemia there was an overall increased length of hospital stay.

To characterize the peripheral immunity and immunity response of patients with sporotrichosis, in this study we determined the lymphocyte subsets in the peripheral blood of Chinese patients with sporotrichosis. In this retrospective study, peripheral blood was collected from 69 sporotrichosis patients (37, fixed cutaneous form; 32 lymphocutaneous) and 66 healthy controls. Lymphocyte subsets were analyzed using flow cytometry. Compared to controls, the percentage of CD8+ T cells was lower in sporotrichosis patients. The percentage of CD8+ T cells in peripheral blood tended to become lower with disease duration and disease severity, although the difference was not statistically significant for either acute, subacute and chronic patients or fixed cutaneous and lymphocutaneous patients. Our data indicate that the decrease of CD8+ T cells in peripheral blood of patients with sporotrichosis is associated with disease severity, although the difference was not statistically significant for either duration or clinical forms of the disease. Combining antifungal agents and immunomodulators in patients with long disease duration and lymphocutaneous may be more beneficial than antifungal monotherapy. Copyright © 2016.

Objective: To study the prevalence, clinical features, electrophysiological features, and severity of peripheral neuropathy in predialysis chronic kidney disease (CKD) patients with respect to severity of renal failure and presence of diabetes mellitus. Materials and Methods: Between May 2015 and December 2016, 200 predialysis CKD patients were assessed prospectively. Results: The prevalence of peripheral neuropathy in predialysis CKD patients in the present study was 45% based on clinical symptoms and 90% electrophysiologically. Mean age of 200 predialysis CKD patients who participated in the study was 53.2 ± 13.2 years. One hundred and thirty-six (68%) patients were male and 64 (32%) patients were female. Mean duration of disease was 2.2 ± 1.6 years. Nearly 45% patients of patients had asymptomatic peripheral neuropathy in the present study, which was more common in mild-to-moderate renal failure group. One hundred twenty-six patients (63%) had definite damage and 54 patients (27%) had early damage. In mild-to-moderate renal failure (n = 100) and severe renal failure patients (n = 100), 88% and 92% had significant peripheral neuropathy, respectively. Most common nerves involved were sural nerve, median sensory nerve, and ulnar sensory nerve. Diabetic patients (97%) showed more severe and high prevalence of peripheral neuropathy when compared to nondiabetic patients (83%). Most common patterns were pure axonal sensorimotor neuropathy and mixed sensorimotor neuropathy. Conclusion: Peripheral neuropathy is common in predialysis patients, prevalence and severity of which increases as renal failure worsens. Predialysis patients with diabetes show higher prevalence and severity of peripheral neuropathy when compared with nondiabetics. PMID:29204008

Myotonic dystrophy type 2 (dystrophia myotonica type 2-DM2) is an autosomal dominant multi-organ disorder. The involvement of the peripheral nervous system was found in 25%-45% of patients with myotonic dystrophy type 1, although limited data are available concerning polyneuropathy in patients with DM2, which was the aim of this study with a thorough presentation of the cases with peripheral neuropathy. Patients with genetically confirmed DM2 underwent motor nerve conduction studies of the median, ulnar, tibial and fibular nerves and sensory nerve conduction studies of the median (second finger), ulnar (fifth finger), radial (forearm) and sural nerves. Seventeen adult patients with DM2 participated in the study. Fifty-three percent (9/17) of our patients had abnormality of one or more attributes (latency, amplitude or conduction velocity) in two or more separate nerves. Four types of neuropathies were found: (i) predominantly axonal motor and sensory polyneuropathy, (ii) motor polyneuropathy, (iii) predominantly demyelinating motor and sensory polyneuropathy and (iv) mutilating polyneuropathy with ulcers. The most common forms are axonal motor and sensory polyneuropathy (29%) and motor neuropathy (18% of all examined patients). No correlations were found between the presence of neuropathy and age, CCTG repeats, blood glucose or HbA1C. Peripheral neuropathy is common in patients with DM2 and presents one of the multisystemic manifestations of DM2. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

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 < 0.001). Furthermore, 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 < 0.001). Transverse versus longitudinal incisions were also associated with significantly lower need for wound vacuum therapy (6% vs. 15%, respectively; P < 0.05) and muscle flap closure (0% vs. 13%, respectively; P < 0.001) for wound complications.

The presence of >5% blasts at "day 14" (D14), in patients undergoing induction chemotherapy for acute myeloid leukemia (AML) is problematic. It is unclear if a second course of chemotherapy for early persistent disease will alter outcome in these patients. We conducted a retrospective study of AML patients undergoing induction chemotherapy where diagnostic, interim (around day 14), and recovery (days 21-42) bone marrow (BM) evaluations were available for review. Of the 113 patients included in the final analysis, 99 (87.6%) achieved CR at hematologic recovery. At D14, 90 patients (79.6%) had <5% blasts and of these, 87 (96.7%) ultimately achieved CR. At D14, Twenty-three (20.4%) patients had residual leukemia (>5% blasts). Of these, 11 (47.8%) received a second course of chemotherapy (double induction [DI]) and 12 (52.2%) were observed until count recovery (single induction [SI]). No significant difference in CR rates was observed between these two groups (58.3% DI group vs. 45.5% SI group, P value = 0.684). In our analysis, D14 BM evaluation did not uniformly identify patients with primary induction failure. To unequivocally determine the value of a D14 marrow assessment in AML, prospective studies in the context of large cooperative group trials are required. Considering our findings and similar reports from others, we propose that D14 marrow assessment should be individualized, and that other factors, such as cytogenetics and early peripheral blood blast clearance should be considered, to identify patients most likely to benefit from interim disease assessment during AML induction therapy. © 2015 Wiley Periodicals, Inc.

This work was a retrospective cohort study of cases from the National Inpatient Sample (NIS). Patients who underwent pituitary surgery from 2005 to 2012 were selected in the NIS. Patients undergoing surgery in July and in non-July months were compared to determine differences in demographics, comorbidities, and complications. Of the 12,939 patients, 1098 (8.5%) underwent pituitary surgery in July. Patients receiving surgery in July had similar demographics and Agency for Healthcare Research and Quality comorbidity values compared with patients receiving surgery in other months. There were no significant differences in mortality, cerebral edema, cerebrospinal fluid leakage, iatrogenic pituitary complications, iatrogenic cerebrovascular accidents, urinary tract infections, pulmonary edema, pulmonary complications, or acute cardiac complications. There were no differences in the rate of postoperative fistulas, hematomas, perforations, or infections. The use of meningeal suturing, pedicled or free-flap reconstruction, and skin reconstruction was more frequent in July. Finally, hospitalization costs in July were similar to costs in other months. The turnover of new residents in July showed no change in complication rates for patients undergoing pituitary surgery. Patient care in July is similar to care during other months, demonstrating that hospitals are adequately supervising surgical residents during this transition. © 2018 ARS-AAOA, LLC.

In an otherwise eligible patient with relapsed lymphoma, inadequate mobilization of peripheral blood stem cells is a limiting factor to proceeding with an autologous hematopoietic cell transplantation (auto-HCT). Multiple strategies have been used to mobilize an adequate number of hematopoietic stem cells (HSCs) with no obvious front-line strategy. We report a single institutional experience mobilizing HSCs using four different approaches in lymphoma patients. We prospectively collected mobilization outcomes on patients planning to undergo auto-HCT at Ohio State University. We report results of first mobilization attempt for all relapsed or refractory lymphoma patients between 2008–2014. We identified 255 lymphoma patients who underwent mobilization for planned auto-HCT. The 255 lymphoma patients underwent the following front line mobilization strategies: 95 (37%) GCSF alone, 38 (15%) chemomobilization (GCSF+chemotherapy), 97 (38%) preemptive day 4 plerixafor, and 25 (10%) rescue day 5 plerixafor. As expected, there were significant differences between cohorts including age, comorbid indices, histology, and amount of prior chemotherapy. After controlling for differences between groups, the odds of collecting 2×106/kg HSCs on the first day of collection and 5×106/kg HSCs in total was highest in the cohort undergoing chemomobilization. In conclusion, our experience highlights the effectiveness of chemomobilization. PMID:28067870

Thrombus located distal to the main or primary pulmonary arteries has been previously viewed as a relative contraindication to surgical pulmonary embolectomy. We compared outcomes for surgical pulmonary embolectomy for submassive and massive pulmonary embolism (PE) in patients with central versus peripheral thrombus burden. All consecutive patients (2011-2016) undergoing surgical pulmonary embolectomy at a single center were retrospectively reviewed. Based on computed tomographic angiography of each patient, central PE was defined as any thrombus originating within the lateral pericardial borders (main or right/left pulmonary arteries). Peripheral PE was defined as thrombus exclusively beyond the lateral pericardial borders, involving the lobar pulmonary arteries or distal. The primary outcome was in-hospital and 90-day survival. 70 patients were identified: 52 (74%) with central PE and 18 (26%) with peripheral PE. Preoperative vital signs and right ventricular dysfunction were similar between the two groups. Compared to the central PE cohort, operative time was significantly longer in the peripheral PE group (191 vs. 210 minutes, p<0.005)). Median right ventricular dysfunction decreased from moderate dysfunction preoperatively to no dysfunction at discharge in both groups. Overall 90-day survival was 94%, with 100% survival in patients with submassive PE in both cohorts. This single center experience demonstrates excellent overall outcomes for surgical pulmonary embolectomy with resolution of right ventricular dysfunction, and comparable morbidity and mortality for central and peripheral PE. In an experienced center and when physiologically warranted, surgical pulmonary embolectomy for peripheral distribution of thrombus is both technically feasible and effective. Copyright © 2018.

Purpose. Restenosis remains a frequent complication after angioplasty in peripheral arterial disease. Inflammation plays a critical role in the vascular response to injury. Effective medical treatment to improve patency after angioplasty is still elusive. The aims of this prospective clinical study were to investigate changes in blood coagulation and inflammatory markers after angioplasty and their significance for restenosis. Methods. Thirty-four patients with peripheral arterial disease underwent angioplasty of the iliac and superficial femoral arteries. Ten patients undergoing diagnostic angiography were included in the study as controls. Plasma levels of tissue factor, prothrombin fragment 1 + 2, D-dimer, P-selectin, C-reactive proteinmore » (CRP), and fibrinogen were analyzed before and after angioplasty. Patients were followed up with angiography after 6 months to assess restenosis. Results. CRP was elevated the day after angioplasty (6.6 mg/l, p = 0.0001) and tended to peak after 1 week (11 mg/l, p = 0.09). There was a significant increase of D-dimer and P-selectin 1-4 hr after angioplasty (0.4 mg/l, p = 0.001 and 68 ng/ml, p = 0.05, respectively). None of the biochemical markers was a statistically significant predictor of restenosis. Conclusion. We have observed a much more prolonged inflammatory response than previously noted, but only minor changes in coagulation activity after angioplasty. The biochemical markers, before and after angioplasty, were not related to restenosis. Further studies are needed to delineate the molecular mechanisms behind these observations and their involvement in thrombosis and restenosis. If these pathways are further defined, improved treatment strategies, including antithrombotic treatments and statins, could be tailored to modulate postprocedural inflammation.« less

Vincristine-induced peripheral neuropathy in pediatric cancer patients

2016-01-01

Vincristine is a chemotherapeutic agent that is a component of many combination regimens for a variety of malignancies, including several common pediatric tumors. Vincristine treatment is limited by a progressive sensorimotor peripheral neuropathy. Vincristine-induced peripheral neuropathy (VIPN) is particularly challenging to detect and monitor in pediatric patients, in whom the side effect can diminish long term quality of life. This review summarizes the current state of knowledge regarding VIPN, focusing on its description, assessment, prediction, prevention, and treatment. Significant progress has been made in our knowledge about VIPN incidence and progression, and tools have been developed that enable clinicians to reliably measure VIPN in pediatric patients. Despite these successes, little progress has been made in identifying clinically useful predictors of VIPN or in developing effective approaches for VIPN prevention or treatment in either pediatric or adult patients. Further research is needed to predict, prevent, and treat VIPN to maximize therapeutic benefit and avoid unnecessary toxicity from vincristine treatment. PMID:27904761

Recent clinical studies have shown a relationship between abnormalities in peripheral perfusion and unfavorable outcome in patients with circulatory shock. Nitroglycerin is effective in restoring alterations in microcirculatory blood flow. The aim of this study was to investigate whether nitroglycerin could correct the parameters of abnormal peripheral circulation in resuscitated circulatory shock patients. This interventional study recruited patients who had circulatory shock and who persisted with abnormal peripheral perfusion despite normalization of global hemodynamic parameters. Nitroglycerin started at 2 mg/hour and doubled stepwise (4, 8, and 16 mg/hour) each 15 minutes until an improvement in peripheral perfusion was observed. Peripheral circulation parameters included capillary refill time (CRT), skin-temperature gradient (Tskin-diff), perfusion index (PI), and tissue oxygen saturation (StO2) during a reactive hyperemia test (RincStO2). Measurements were performed before, at the maximum dose, and after cessation of nitroglycerin infusion. Data were analyzed by using linear model for repeated measurements and are presented as mean (standard error). Of the 15 patients included, four patients (27%) responded with an initial nitroglycerin dose of 2 mg/hour. In all patients, nitroglycerin infusion resulted in significant changes in CRT, Tskin-diff, and PI toward normal at the maximum dose of nitroglycerin: from 9.4 (0.6) seconds to 4.8 (0.3) seconds (P < 0.05), from 3.3 °C (0.7 °C) to 0.7 °C (0.6 °C) (P < 0.05), and from [log] -0.5% (0.2%) to 0.7% (0.1%) (P < 0.05), respectively. Similar changes in StO2 and RincStO2 were observed: from 75% (3.4%) to 84% (2.7%) (P < 0.05) and 1.9%/second (0.08%/second) to 2.8%/second (0.05%/second) (P < 0.05), respectively. The magnitude of changes in StO2 was more pronounced for StO2 of less than 75%: 11% versus 4%, respectively (P < 0.05). Dose-dependent infusion of nitroglycerin reverted abnormal peripheral perfusion and

Peripheral facial nerve paralysis in children might be an alarming sign of serious disease such as malignancy, systemic disease, congenital anomalies, trauma, infection, middle ear surgery, and hypertension. The cases of 40 consecutive children and adolescents who were diagnosed with peripheral facial nerve paralysis at Baskent University Adana Hospital Pediatrics and Pediatric Neurology Unit between January 2010 and January 2013 were retrospectively evaluated. We determined that the most common cause was Bell palsy, followed by infection, tumor lesion, and suspected chemotherapy toxicity. We noted that younger patients had generally poorer outcome than older patients regardless of disease etiology. Peripheral facial nerve paralysis has been reported in many countries in America and Europe; however, knowledge about its clinical features, microbiology, neuroimaging, and treatment in Turkey is incomplete. The present study demonstrated that Bell palsy and infection were the most common etiologies of peripheral facial nerve paralysis. © The Author(s) 2014.

Objective: To examine the incidence of nonsynonymous missense variants in SCN9A (NaV1.7), SCN10A (NaV1.8), and SCN11A (NaV1.9) in patients with painful and nonpainful peripheral neuropathy. Methods: Next-generation sequencing was performed on 457 patient DNA samples provided by the Peripheral Neuropathy Research Registry (PNRR). The patient diagnosis was as follows: 278 idiopathic peripheral neuropathy (67% painful and 33% nonpainful) and 179 diabetic distal polyneuropathy (77% painful and 23% nonpainful). Results: We identified 36 (SCN9A), 31 (SCN10A), and 15 (SCN11A) nonsynonymous missense variants, with 47.7% of patients carrying a low-frequency (minor allele frequency <5%) missense variant in at least 1 gene. The incidence of previously reported gain-of-function missense variants was low (≤3%), and these were detected in patients with and without pain. There were no significant differences in missense variant allele frequencies of any gene, or SCN9A haplotype frequencies, between PNRR patients with painful or nonpainful peripheral neuropathy. PNRR patient SCN9A and SCN11A missense variant allele frequencies were not significantly different from the Exome Variant Server, European American (EVS-EA) reference population. For SCN10A, there was a significant increase in the alternate allele frequency of the common variant p.V1073A and low-frequency variant pS509P in PNRR patients compared with EVS-EA and the 1000 Genomes European reference populations. Conclusions: These results suggest that identification of a genetically defined subpopulation for testing of NaV1.7 inhibitors in patients with peripheral neuropathy is unlikely and that additional factors, beyond expression of previously reported disease “mutations,” are more important for the development of painful neuropathy than previously discussed.

Anemia correlates with worse outcomes in patients undergoing percutaneous coronary intervention (PCI), improved anemia can improve the outcomes in patients who underwent PCI. But the influence of anemia on long-term ischemic events after PCI remains unknown. We analyzed 8,825 consecutive patients who underwent PCI at General Hospital of Shenyang Military Region and identified 581 patients with anemia. Patients (anemia vs. no anemia) were compared using a propensity score analysis to best match between groups. The main outcome of this study is 3-year ischemic events after PCI, the secondary outcome of this study is 3-year mortality and major adverse cardiac events (MACE) after PCI. Compared with nonanemic patients, anemic patients were often female (38.90% vs. 14.51%) and elder patients (66.44% vs. 34.95%). Anemic patients have lower left ventricular ejection fraction (LVEF) and creatinine clearance (Ccr) and were more likely to have history of cardiovascular and cerebrovascular diseases, hypertension, peripheral vascular diseases (PVD) (P<0.05). However, the prevalences of diabetes and hyperlipidemia were lower in anemic patients (P<0.01). Anemia was an independent predictor for 3-year ischemic events [hazard ratio (HR): 2.20, 95% confidence intervals (CI): 1.61-3.00, P<0.01], 3-year mortality (HR: 3.58, 95% CI: 1.75-7.32, P<0.01) and 3-year MACE (HR: 2.14, 95% CI: 1.64-2.79, P<0.01) after PCI in post-match samples. The incidence of 3-year ischemic events was 41.0% and 19.3% in anemic and nonanemic patients, respectively. Anemia is an independent predictor for 3-year ischemic events, 3-year mortality and 3-year MACE in patients who underwent PCI. Further studies need to explore the impact of the pathogenesis and progress, prevention and therapy of anemia on the outcome of patients undergoing PCI.

AIM: To investigate the effect of pain relief after infusion of ropivacaine at port sites at the end of surgery. METHODS: From October 2006 to September 2007, 72 patients undergoing laparoscopic cholecystectomy (LC) were randomized into two groups of 36 patients. One group received ropivacaine infusion at the port sites at the end of LC and the other received normal saline. A visual analog scale was used to assess postoperative pain when the patient awakened in the operating room, 6 and 24 h after surgery, and before discharge. The amount of analgesics use was also recorded. The demographics, laboratory data, hospital stay, and perioperative complications were compared between the two groups. RESULTS: There was no difference between the two groups preoperatively in terms of demographic and laboratory data. After surgery, similar operation time, blood loss, and no postoperative morbidity and mortality were observed in the two groups. However, a significantly lower pain score was observed in the patients undergoing LC with local anesthesia infusion at 1 h after LC and at discharge. Regarding analgesic use, the amount of meperidine used 1 h after LC and the total used during admission were lower in patients undergoing LC with local anesthesia infusion. This group also had a shorter hospital stay. CONCLUSION: Local anesthesia with ropivacaine at the port site in LC patients significantly decreased postoperative pain immediately. This explains the lower meperidine use and earlier discharge for these patients. PMID:19452582

Diabetes mellitus (DM) can present complications of neuropathy and peripheral arterial disease with high risk for developing foot ulcers and consequent amputations. To identify the association between peripheral vascular disease, and neuropathy in type 2 Diabetes mellitus patients from the Hospital General de Zona No. 1 IMSS in Colima, Mexico. Cross-sectional study of 80 patients with diabetes mellitus evaluated by means of the Edinburgh Claudication Questionnaire, Michigan Neuropathy Screening Instrument, ankle-arm index, Motor Nerve Conduction Velocity and H-reflex. 51 women and 29 men were studied. Mean age was 53.9 +/- 9.6 years, mean diabetes mellitus progression was 8 +/- 6.6 years and mean glucose level was 283 +/- 110 mg/mL. Neuropathy presented in 65 patients (81.2%). Ankle/arm index revealed 19% of patients presented with moderate peripheral vascular insufficiency. Motor Nerve Conduction Velocity was abnormal in 40% of patients and H-reflex was absent in 70%. Grade 2 motor-sensitive polyneuropathy was found in 70-80% of patients and moderate peripheral vascular insufficiency in 19%. It can thus be inferred that the complication of diabetic neuropathy appears before that of peripheral vessel damage.

Peripherally inserted central catheters (PICC) are increasingly used in hospitalized patients. The benefit can be offset by complications such as upper extremity deep vein thrombosis (UEDVT). Retrospective study of patients who received a PICC while hospitalized at the Methodist University Hospital (MUH) in Memphis, TN. All adult consecutive patients who had PICCs inserted during the study period and who did not have a UEDVT at the time of PICC insertion were included in the study. A UEDVT was defined as a symptomatic event in the ipsilateral extremity, leading to the performance of duplex ultrasonography, which confirmed the diagnosis of UEDVT. Pulmonary embolism (PE) was defined as a symptomatic event prompting the performance of ventilation-perfusion lung scan or spiral computed tomography (CT). Among 777 patients, 38 patients experienced 1 or more venous thromboembolisms (VTEs), yielding an incidence of 4.89%. A total of 7444 PICC-days were recorded for 777 patients. This yields a rate of 5.10 VTEs/1000 PICC-days. Compared to patients whose PICC was inserted in the SVC, patients whose PICC was in another location had an increased risk (odds ratio = 2.61 [95% CI = 1.28-5.35]) of VTE. PICC related VTE was significantly more common among patients with a past history of VTE (odds ratio = 10.83 [95% CI = 4.89-23.95]). About 5% of patients undergoing PICC placement in acute care hospitals will develop thromboembolic complications. Thromboembolic complications were especially common among persons with a past history of VTE. Catheter tip location at the time of insertion may be an important modifiable risk factor.

Cardiovascular mortality is the leading cause of death in patients with prostate cancer (PC), metabolic syndrome (MS) being related to it. The main objective of this study was to determine the prevalence of MS in patients with CP undergoing androgen suppression (AS). We performed a retrospective study of cases and controls that included 159 patients. The study group was made up of 53 patients with PC undergoing SA for a period exceeding 12 months. The control group was formed by 53 patients with PC at the time of diagnosis and 53 patients with negative prostate biopsy. All patients were evaluated for presence of MS according to NCEP-ATPIII criteria. Prevalence of MS in patients without PC was 32.1% and in those with non-treated PC 35.8%, P = .324. In patients with PC undergoing AS, prevalence of MS was 50.9%, P < .001. When AS duration was less than 36 months, prevalence of MS was 44.0% and when greater than 36 months 57.1%, P < .001. Waist circumference and hyperglycemia were the two MS components that significantly increased. AS and its duration were independent predictors factors for the development of MS. Continuous AS therapy increases the prevalence of MS and especially waist circumference and hyperglycemia. Development of MS increases according to AS duration. Copyright © 2013 AEU.

Boyce, Brenda A Brady; Yee, Barbara Homer

2012-08-01

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.

We aimed to investigate the relationship between peripheral vertigo and inflammation by using the neutrophil-to-lymphocyte ratio (NLR) as an inflammatory marker. We recruited 103 patients with peripheral vertigo (71 women, 32 men; mean age, 39.8 ± 14.7 years) who presented to the Otolaryngology Department of Dumlupinar University Hospital. Vertigo patients with systemic diseases, neurological disorders, malignancy or any inflammatory disease that could alter the NLR were excluded from the study. We also enrolled 103 age- and sex-matched healthy subjects (controls; 82 women, 21 men; mean age, 36.7 ± 13.5 years) who underwent routine checkups in our hospital. The vertigo patients underwent full otolaryngologic and neurologic examinations and audiometric tests to rule out any other pathology causing the peripheral vertigo. NLR was calculated in all subjects and was compared between the patient and control groups. There were no significant differences between the study and control groups in terms of lipid profiles, liver-function tests, white blood cell (WBC) count, hemoglobin level, mean platelet volume, and vitamin B12 and folate levels. The mean NLR was significantly higher in the patients than in the controls (P<0.05). In conclusion, this study, which was the first to investigate the relationship between the NLR and peripheral vertigo, found that the NLR is significantly higher among peripheral vertigo patients than among healthy controls. This result suggests that the NLR is a novel potential marker of stress in peripheral vertigo patients. Copyright © 2014 Elsevier Inc. All rights reserved.

Sequential changes in lung density measured by CT are potentially sensitive and convenient monitors of lung abnormalities following total body irradiation (TBI). Methods have been developed to compare pre- and post-TBI CT of lung. The average local features of a cross-sectional lung slice are extracted from three peripheral regions of interest in the anterior, posterior, and lateral portions of the CT image. Also, density profiles across a specific region may be obtained. These may be compared first for verification of patient position and breathing status and then for changes between pre- and post-TBI. These may also be compared with radiation dose profiles through the lung. A preliminary study on 21 leukemia patients undergoing total body irradiation indicates the following: (a) Density gradients of patients' lungs in the antero-posterior direction show a marked heterogeneity before and after transplantation compared with normal lungs. The patients with departures from normal density gradients pre-TBI correlate with later pulmonary complications. (b) Measurements of average peripheral lung densities have demonstrated that the average lung density in the younger age group is substantially higher: pre-TBI, the average CT number (1,000 scale) is -638 +/- 39 Hounsfield unit (HU) for 0-10 years old and -739 +/- 53 HU for 21-40 years old. (c) Density profiles showed no post-TBI regional changes in lung density corresponding to the dose profile across the lung, so no differentiation of a radiation-specific effect has yet been possible. Computed tomographic density profiles in the antero-posterior direction are successfully used to verify positioning of the CT slice and the breathing level of the lung.

Tranexamic acid reduces the risk of bleeding among patients undergoing cardiac surgery, but it is unclear whether this leads to improved outcomes. Furthermore, there are concerns that tranexamic acid may have prothrombotic and proconvulsant effects. In a trial with a 2-by-2 factorial design, we randomly assigned patients who were scheduled to undergo coronary-artery surgery and were at risk for perioperative complications to receive aspirin or placebo and tranexamic acid or placebo. The results of the tranexamic acid comparison are reported here. The primary outcome was a composite of death and thrombotic complications (nonfatal myocardial infarction, stroke, pulmonary embolism, renal failure, or bowel infarction) within 30 days after surgery. Of the 4662 patients who were enrolled and provided consent, 4631 underwent surgery and had available outcomes data; 2311 were assigned to the tranexamic acid group and 2320 to the placebo group. A primary outcome event occurred in 386 patients (16.7%) in the tranexamic acid group and in 420 patients (18.1%) in the placebo group (relative risk, 0.92; 95% confidence interval, 0.81 to 1.05; P=0.22). The total number of units of blood products that were transfused during hospitalization was 4331 in the tranexamic acid group and 7994 in the placebo group (P<0.001). Major hemorrhage or cardiac tamponade leading to reoperation occurred in 1.4% of the patients in the tranexamic acid group and in 2.8% of the patients in the placebo group (P=0.001), and seizures occurred in 0.7% and 0.1%, respectively (P=0.002 by Fisher's exact test). Among patients undergoing coronary-artery surgery, tranexamic acid was associated with a lower risk of bleeding than was placebo, without a higher risk of death or thrombotic complications within 30 days after surgery. Tranexamic acid was associated with a higher risk of postoperative seizures. (Funded by the Australian National Health and Medical Research Council and others; ATACAS Australia New Zealand

BK virus (BKV) reactivation has been increasingly associated with the occurrence of late-onset hemorrhagic cystitis (HC) after allogeneic hematopoietic SCT (allo-HSCT) resulting in morbidity and sometimes mortality. We investigated the incidence, risk factors and outcome of BKV-HC in 323 consecutive adult patients undergoing allo-HSCT over a 5-year period. BK viremia values for HC staging were evaluated, as well as the medico-economic impact of the complication. Forty-three patients developed BKV-HC. In univariate analysis, young age (P=0.028), unrelated donor (P=0.0178), stem cell source (P=0.0001), HLA mismatching (P=0.0022) and BU in conditioning regimen (P=0.01) were associated with a higher risk of developing BKV-HC. In multivariate analysis, patients receiving cord blood units (CBUs) (P=0.0005) and peripheral blood stem cells (P=0.011) represented high-risk subgroups for developing BKV-HC. BK viremia was directly correlated to HC severity (P=0.011) with a 3 to 6-log peak being likely associated with grades 3 or 4 HC. No correlation was found between BKV-HC and acute graft versus host disease or mortality rate. Patients with BKV-HC required a significantly longer duration of hospitalization (P<0.0001), more RBC (P=0.0003) and platelet transfusions (P<0.0001). Over the 5-year study period, the financial cost of the complication was evaluated at \\[euro]2 376 076 ($3 088 899). Strategies to prevent the occurrence of late-onset BKV-HC after allo-HSCT are urgently needed, especially in CBU and peripheral blood stem cell recipients. BK viremia correlates with the severity of the disease. Prospective studies are required to test prophylactic approaches.

With the transition from infectious disease and acute illness to chronic disease and degenerative illness as leading causes of death, health-related quality of life has become an important aspect in assessing the burden of chronic disease. The quality of life of haemodialysis patients has been studied extensively; however, very limited research using exploratory descriptive design has been carried out in this area in China. The aim of this study was to explore health-related quality of life of end-stage renal disease patients undergoing haemodialysis in China. This study used the qualitative research design approach. A semi-structured, in-depth interview was conducted with 16 haemodialysis patients in two hospitals using Colaizzi's phenomenological method to transcribe and analyse the data. The results of this study showed that dialysis patients show improvement in physical competence, but they also experienced emotional instability and psychological distress, financial burdens, inadequate disease knowledge and less social support which influenced their quality of life. To optimise the patients undergoing dialysis health-related quality of life, support of psycho-social-economical aspects should be enhanced. Health care providers should give haemodialysis patients thorough health education, individualised psychological and emotional intervention and adequate social support to optimise health-related quality of life.

The peripheral artery questionnaire (PAQ) is a disease-specific health status measure of patients with peripheral artery disease (PAD). Whether the PAQ scores are associated with a PAD diagnosis among patients with symptoms suspicious for PAD is unknown and could help increase the pretest probability of ankle brachial index (ABI) screening among patients with suspicious symptoms. The PAQ was completed by 567 patients evaluated for potential intermittent claudication at six tertiary centres. Demographics, medical history, physical examination findings and the PAQ domain scores were compared with ABI. A diagnostic threshold < 0.90 for a PAD diagnosis was assessed with a ROC of PAQ scores. The correlation between the PAQ Summary Score and ABI was also calculated. The PAQ Summary Score was significantly lower in patients with low ABI as compared with those having a normal ABI (37.6 ± 19.0 vs. 70.1 ± 22.7, p < 0.001). The PAQ Summary Score and ABI were highly correlated (r = 0.56, p < 0.001) and the optimal PAQ Summary Score for predicting low ABI was 50.3 (AUC = 0.86, sensitivity 80.3%, specificity 78.3%). The PAQ Summary Score was associated with an increased likelihood of PAD in patients with suspected PAD symptoms, and a low summary score (≤ 50.3) was an optimal threshold for predicting PAD among patients referred for ABI. © 2014 John Wiley & Sons Ltd.

This study was designed to investigate the effects of aromatherapy on pruritus in patients with chronic renal failure undergoing hemodialysis. The participants were 29 adult patients living in Seoul, Korea. Thirteen patients were assigned to the experimental group and received the aromatherapy massage on the arm 3 times a week for 4 weeks. Pruritus score, skin pH, stratum corneum hydration, and pruritus-related biochemical markers were measured before and after the treatment. The results showed that pruritus score was significantly decreased after aromatherapy. Skin pH showed no significant changes in either group while stratum corneum hydration increased significantly in the experimental group after aromatherapy. The results support the use aromatherapy as a useful and effective method of managing pruritus in patients undergoing hemodialysis.

The association of operative duration with the risk of venous thromboembolism (VTE) has not been quantified in neurosurgery. To investigate the association of surgical duration for several neurosurgical procedures and the incidence of VTE. We performed a retrospective cohort study involving patients who underwent neurosurgical procedures from 2005 to 2012 and were registered in the American College of Surgeons National Quality Improvement Project registry. In order to control for confounding, we used multivariable regression models, and propensity score conditioning. During the study period, there were 94 747 patients, who underwent neurosurgical procedures, and met the inclusion criteria. Of these, 1358 (1.0%) developed VTE within 30 days postoperatively. Multivariable logistic regression demonstrated an association of longer operative duration with higher 30-day incidence of VTE (odds ratio [OR], 1.22; 95% confidence interval [CI], 1.19-1.25). Compared with procedures of moderate duration (third quintile, 40-60th percentile), patients undergoing the longest procedures (>80th percentile) had higher odds (OR, 3.15; 95% CI, 2.49-3.99) of developing VTE. The shortest procedures (<20th percentile) were associated with a decreased incidence of VTE (OR, 0.51; 95% CI, 0.27-0.76) in comparison to those of moderate duration. The same associations were present in propensity score-adjusted models, and models stratified by subgroups of cranial, spinal, peripheral nerve, and carotid procedures. In a cohort of patients from a national prospective surgical registry, increased operative duration was associated with increased incidence of VTE for neurosurgical procedures. These results can be used by neurosurgeons to inform operative management, and to stratify patients with regard to VTE risk. Copyright © 2016 by the Congress of Neurological Surgeons

Patients with peripheral arterial disease (PAD) undergoing percutaneous coronary intervention (PCI) are at elevated risk of ischemic and bleeding events. However, the optimal duration of dual antiplatelet therapy (DAPT) after PCI in patients with PAD remains unclear. A systematic literature search was performed through June 2017 using PubMed, EMBASE and Cochrane databases with the following key terms: "dual antiplatelet therapy", "P2Y12 inhibitor", "myocardial infarction", "percutaneous coronary intervention", "stent", "peripheral arterial disease", and "ankle-brachial index". The analysis was restricted to randomized trials published in English in patients with PAD receiving extended DAPT (> 12-month) after PCI. Overall analysis was performed using Review Manager 5.3 with the Mantel-Haenszel method. Two randomized controlled trials involving 895 patients were included in this review. Compared to the placebo group, there was no statistical significance in the occurrence of major adverse cardiovascular and cerebrovascular events (MACCE) in patients receiving extended DAPT (odds ratio (OR) 0.76, 95% confidence interval (CI) 0.37 - 1.57; P = 0.46). The results were associated with substantial heterogeneity (I 2 = 71%, P = 0.07). Extended DAPT was not significantly associated with increased moderate/severe bleeding events (OR 1.63, 95% CI 0.84 - 3.18; P = 0.15; I 2 = 0%, P = 0.59). The extended DAPT was associated with 82% relative risk reduction in the events of definite/probably stent thrombosis. Among patients with PAD, extended DAPT after PCI resulted in a non-significant difference in ischemic and bleeding events compared to placebo, respectively. The routine use of extended DAPT in this cohort should be carefully evaluated.

Changing sociodemographic patterns with an increase in the age of childbirth have affected fertility rates worldwide. With advancing reproductive medicine, assisted reproductive techniques (ARTs) are becoming common. While dermatological manifestations in normal pregnancies have been well documented, there is a paucity of data regarding cutaneous manifestations in patients undergoing ART. The objectives of our study were to estimate the incidence and types of dermatological manifestations in patients undergoing in vitro fertilisation (IVF) and to study their associations with age, type of infertility, and outcome of the procedure. A prospective cohort of 200 patients undergoing IVF in a tertiary care centre was observed for occurrence of any dermatological manifestations from initiation of the IVF protocol to the outcome of the procedure at 3 weeks after embryo transfer. Dermatological manifestations were seen in 27% of the study group, with urticaria being the most common cutaneous finding seen in 13.5%, followed by acneform eruptions (3%). Twenty-six (96.3%) of patients who manifested with urticaria were on progesterone. No statistically significant association was found between the occurrence of dermatological manifestations and the outcome of IVF, type of infertility, history of ART, and ovum donation in our study. Association between the age of the patient and the outcome of IVF cycle was statistically significant. Dermatological manifestations are seen in almost one-quarter of patients undergoing IVF, with progesterone-induced urticaria being the most common. Occurrence of cutaneous manifestations has no significant association with the outcome of IVF.

This study was designed to evaluate the effectiveness of lavender aromatherapy on pain, anxiety, and level of satisfaction associated with the peripheral venous cannulation (PVC) in patients undergoing surgery. One hundred and six patients undergoing surgery were randomized to receive aromatherapy with lavender essential oil (the lavender group) or a placebo (the control group) during PVC. The patients' pain, anxiety, and satisfaction scores were measured. There was no statistically significantly difference between the groups in terms of demographic data. After cannulation, the pain and anxiety scores (anxiety 2) of the patients in the lavender group were significantly lower than the control group (for p = 0.01 for pain scores; p < 0.001 for anxiety 2 scores). In addition, patient satisfaction was significantly higher in the lavender group than in the control group (p = 0.003). Lavender aromatherapy had beneficial effects on PVC pain, anxiety, and satisfaction level of patients undergoing surgery. Copyright © 2016 Elsevier Ltd. All rights reserved.

There are relatively few studies, which focus on peripheral neuropathy in large cohorts of genetically characterized patients with mitochondrial disorders. This study sought to analyze the pattern of peripheral neuropathy in a cohort of patients with mitochondrial disorders. The study subjects were derived from a cohort of 52 patients with a genetic diagnosis of mitochondrial disorders seen over a period of 8 years (2006-2013). All patients underwent nerve conduction studies and those patients with abnormalities suggestive of peripheral neuropathy were included in the study. Their phenotypic features, genotype, pattern of peripheral neuropathy and nerve conduction abnormalities were analyzed retrospectively. The study cohort included 18 patients (age range: 18 months-50 years, M:F- 1.2:1).The genotype included mitochondrial DNA point mutations (n=11), SURF1 mutations (n=4) and POLG1(n=3). Axonal neuropathy was noted in 12 patients (sensori-motor:n=4; sensory:n=4; motor:n=4) and demyelinating neuropathy in 6. Phenotype-genotype correlations revealed predominant axonal neuropathy in mtDNA point mutations and demyelinating neuropathy in SURF1. Patients with POLG related disorders had both sensory ataxic neuropathy and axonal neuropathy. A careful analysis of the family history, clinical presentation, biochemical, histochemical and structural analysis may help to bring out the mitochondrial etiology in patients with peripheral neuropathy and may facilitate targeted gene testing. Presence of demyelinating neuropathy in Leigh's syndrome may suggest underlying SURF1 mutations. Sensory ataxic neuropathy with other mitochondrial signatures should raise the possibility of POLG related disorder. Copyright © 2015. Published by Elsevier B.V.

Both cutaneous and uveal melanoma undergo haematogenous dissemination. Detection of tyrosinase mRNA by reverse transcription-polymerase chain reaction (RT-PCR) has been described as an extremely sensitive way of detecting circulating viable melanoma cells in the peripheral venous blood, and this technique may be of value in the early detection of dissemination. Also, it has been suggested that surgical manipulation of the eye, such as occurs during enucleation, can provoke uveal melanoma dissemination. The purpose of this study was to evaluate whether tyrosinase mRNA is detectable in the peripheral blood of patients with uveal and cutaneous melanoma and in patients with uveal melanoma undergoing surgical procedures on the eye harbouring the tumour. Venous blood samples from 36 patients diagnosed as having active uveal melanoma and from six patients with advanced metastatic cutaneous melanoma were analysed. In addition, blood samples were spiked with known numbers of cells from three cell lines and four primary uveal melanoma cultures. The reported sensitivity of the technique was confirmed, with an ability to detect down to one cell per ml of blood. All 51 blood samples from the 36 patients with uveal melanoma were negative, and this included 20 perioperative blood samples. The test was also negative for the six patients with advanced cutaneous melanoma. There were two positives among 31 control samples analysed. This study demonstrates that there are far fewer circulating viable melanocytes than has been previously supposed in patients with melanoma and that the RT-PCR is of no clinical value in detecting metastatic melanoma disease. There was no evidence for surgery causing a bolus of melanoma cells to enter the peripheral circulation. Images Figure 1 Figure 2 PMID:7599046

To study the influence of peripheral neuropathy on intermittent claudication in patients with Type 2 diabetes (T2DM). Twenty-five patients with T2DM were grouped according to the ankle/brachial index (ABI): 10 with ABI > 0.9 without peripheral artery disease (PAD; group T2DM) and 15 with ABI < 0.9 with PAD (group T2DM + PAD). Twelve individuals without T2DM with PAD (group PAD without T2DM) were also enrolled. Tests for peripheral neuropathy were performed in all patients. ABI, rate pressure product, prothrombin fragments 1 + 2 (F1+2), thrombin-anti-thrombin complex (TAT), and d-dimer were measured before and after a treadmill test. During exercise both initial and absolute claudication distance and electrocardiogram readings were recorded. We found mild peripheral neuropathy in 20% of group T2DM and 46.7% of group T2DM + PAD (P < 0.01). After exercise, the rate pressure product increased in each group; ABI fell in T2DM + PAD (P < 0.0001) and in PAD without T2DM (P = 0.0005); the fall was greater in the latter group. Initial and absolute claudication distances were similar in PAD patients. In group T2DM + PAD, absolute claudication distance was longer in the subgroup without peripheral neuropathy (P < 0.05), whereas ABI and rate pressure products were similar. F1+2 values at rest were higher in group T2DM + PAD. After exercise, F1+2 values and TAT increased only in group PAD without T2DM. Only group PAD without T2DM experienced muscular ischaemia, whereas group T2DM + PAD did not. Mild peripheral neuropathy may have prevented them from reaching the point of muscular ischaemia during the treadmill test, because they stopped exercising with the early onset of pain. Reaching a false absolute claudication distance may induce ischaemic preconditioning. These findings suggest a possible protective role of mild peripheral neuropathy in T2DM patients with intermittent claudication, by preventing further activation of coagulation during treadmill testing.

Sinusitis is a common morbidity in general population, however little is known about its occurrence in severely immunocompromised patients undergoing allogeneic hematopoietic stem cell transplantation. The aim of the study was to analyze the literature concerning sinusitis in patients undergoing allogeneic bone marrow transplantation. An electronic database search was performed with the objective of identifying all original trials examining sinusitis in allogeneic hematopoietic stem cell transplant recipients. The search was limited to English-language publications. Twenty five studies, published between 1985 and 2015 were identified, none of them being a randomized clinical trial. They reported on 31-955 patients, discussing different issues i.e. value of pretransplant sinonasal evaluation and its impact on post-transplant morbidity and mortality, treatment, risk factors analysis. Results from analyzed studies yielded inconsistent results. Nevertheless, some recommendations for good practice could be made. First, it seems advisable to screen all patients undergoing allogeneic hematopoietic stem cell transplantation with Computed Tomography (CT) prior to procedure. Second, patients with symptoms of sinusitis should be treated before hematopoietic stem cell transplantation (HSCT), preferably with conservative medical approach. Third, patients who have undergone hematopoietic stem cell transplantation should be monitored closely for sinusitis, especially in the early period after transplantation.

Ehlers-Danlos syndrome (EDS) is an inherited disease characterized by defects in various collagens or their post translational modification, with an incidence estimated at 1 in 5000. Performance of peripheral nerve block in patients with EDS is controversial, due to easy bruising and hematoma formation after injections as well as reports of reduced block efficacy. The objective of this study was to review the charts of EDS patients who had received peripheral nerve block for any evidence of complications or reduced efficacy. Case series, chart review. Academic medical center. Patients with a confirmed or probable diagnosis of EDS who had received a peripheral nerve block in the last 3 years were identified by searching our institutions electronic medical record system. The patients were classified by their subtype of EDS. Patients with no diagnosed subtype were given a probable subtype based on a chart review of the patient's symptoms. Patient charts were reviewed for any evidence of complications or reduced block efficacy. A total of 21 regional anesthetics, on 16 unique patients were identified, 10 of which had a EDS subtype diagnosis. The majority of these patients had a diagnosis of hypermobility-type EDS. No block complications were noted in any patients. Two block failures requiring repeat block were noted, and four patients reported uncontrolled pain on postoperative day one despite successful placement of a peripheral nerve catheter. Additionally, blocks were performed without incident in patients with classical-type and vascular-type EDS although the number was so small that no conclusions can be drawn about relative safety of regional anesthesia in these groups. This series fails to show an increased risk of complications of peripheral nerve blockade in patients with hypermobility-type EDS. Copyright © 2016 Elsevier Inc. All rights reserved.

Our objective was to describe our experience of managing a cohort of adult patients prescribed direct oral anticoagulants (DOACs) undergoing dentoalveolar procedures between November 2012 and May 2016. Prior to conducting a procedure a formal assessment was made of each patient's anticoagulation treatment. A specific plan was then formulated, balancing the risk of bleeding with the risk of thrombosis. Patients received a telephone consultation one week following treatment to assess any post-operative bleeding. Eighty-two patients underwent 111 oral surgical procedures, the majority of which were dental extractions. In the case of 35 (32%) procedures, advice was given to omit the DOAC, either before or after treatment. There was no bleeding following the majority of procedures. Persistent bleeding followed 15 (13.5%) procedures, of which 7 (6.3%) procedures required specific intervention. The majority of patients prescribed DOACs can undergo dentoalveolar procedures safely. Important considerations when planning treatment are: (i) when the patient usually takes their dose of DOAC, (ii) the time the procedure is performed and, (iii) when the DOAC is taken post-procedure. In our experience, if these factors are considered carefully, omission of DOAC doses is unlikely to be required for most patients.

Summary The aim of this study was to evaluate knowledge of electromyography (EMG) in patients undergoing the procedure. In one year, 1,586 consecutive patients (mean age 56 years; 58.8% women) were admitted to two EMG labs to undergo EMG for the first time. The patients found to be “informed” about the how an EMG examination is performed and about the purpose of EMG numbered 448 (28.2%), while those found to be “informed” only about the manner of its execution or only about its purpose numbered 161 (10.2%) and 151 (9.5%), respectively. The remaining 826 (52.1%) patients had either no information, or the information they had was very poor or incorrect (this was particularly true if they had been consulting websites). Being “informed” was associated with level of education (high), type of referring physician (specialist) and with an appropriate referral diagnosis specified in the EMG request. The quality of patient information on EMG was found to be very poor and could be improved. Physicians referring patients for EMG examinations, especially general practitioners, should assume primary responsibility for patient education and counseling in this field. PMID:25473740

The American Academy of Orthopaedic Surgeons, in collaboration with the American Dental Association, has developed Appropriate Use Criteria (AUC) for the Management of Patients with Orthopaedic Implants Undergoing Dental Procedures. Evidence-based information, in conjunction with the clinical expertise of physicians, was used to develop the criteria to improve patient care and obtain best outcomes while considering the subtleties and distinctions necessary in making clinical decisions. The Management of Patients with Orthopaedic Implants Undergoing Dental Procedures AUC clinical patient scenarios were derived from indications of patients with orthopaedic implants presenting for dental procedures, as well as from current evidence-based clinical practice guidelines and supporting literature to identify the appropriateness of the use of prophylactic antibiotics. The 64 patient scenarios and 1 treatment were developed by the writing panel, a group of clinicians who are specialists in this AUC topic. Next, a separate, multidisciplinary, voting panel (made up of specialists and nonspecialists) rated the appropriateness of treatment of each patient scenario using a 9-point scale to designate a treatment as Appropriate (median rating, 7 to 9), May Be Appropriate (median rating, 4 to 6), or Rarely Appropriate (median rating, 1 to 3).

The concomitant presence of mitral stenosis (MS) in the setting of symptomatic aortic stenosis represent a clinical challenge. Little is known regarding the outcome of mitral stenosis (MS) patients undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). Therefore, we sought to study the outcome of MS patients undergoing aortic valve replacement (AVR). Using weighted data from the National Inpatient Sample (NIS) database between 2011 and 2014, we identified patients who were diagnosed with MS. Patients who had undergone TAVR as a primary procedure were identified and compared to patients who had SAVR. Univariate and multivariate logistic regression analysis were performed for the outcomes of in-hospital mortality, length of stay (LOS), blood transfusion, postprocedural hemorrhage, vascular, cardiac and respiratory complications, permanent pacemaker placement (PPM), postprocedural stroke, acute kidney injury (AKI), and discharge to an outside facility. A total of 4524 patients were diagnosed with MS, of which 552 (12.2%) had TAVR and 3972 (87.8%) had SAVR. TAVR patients were older (79.9 vs 70.0) with more females (67.4% vs 60.0%) and African American patients (7.7% vs 7.1%) (P < 0.001). In addition, the TAVR group had more comorbidities compared to SAVR in term of coronary artery disease (CAD), congestive heart failure (CHF), chronic lung disease, hypertension (HTN), chronic kidney disease (CKD), and peripheral vascular disease (PVD) (P < 0.001 for all). Using Multivariate logistic regression, and after adjusting for potential risk factors, TAVR patients had lower in-hospital mortality (7.9% vs 8.1% adjusted Odds Ratio [aOR], 0.615; 95% confidence interval [CI], 0.392-0.964, P = 0.034), shorter LOS. Also, TAVR patients had lower rates of cardiac and respiratory complications, PPM, AKI, and discharge to an outside facility compared with the SAVR group.

Diverticular disease of the colon is frequent in clinical practice, and a large number of patients each year undergo surgical procedures worldwide for their symptoms. Thus, there is a need for better knowledge of the basic pathophysiologic mechanisms of this disease entity. Because patients with colonic diverticular disease have been shown to display abnormalities of the enteric nervous system, we assessed the frequency of myenteric plexitis (i.e. the infiltration of myenteric ganglions by inflammatory cells) in patients undergoing surgery for this condition. We analyzed archival resection samples from the proximal resection margins of 165 patients undergoing left hemicolectomy (60 emergency and 105 elective surgeries) for colonic diverticulitis, by histology and immunochemistry. Overall, plexitis was present in almost 40% of patients. It was subdivided into an eosinophilic (48%) and a lymphocytic (52%) subtype. Plexitis was more frequent in younger patients; and it was more frequent in those undergoing emergency surgery (50%), compared to elective (28%) surgery (p = 0.007). All the severe cases of plexitis displayed the lymphocytic subtype. In conclusion, myenteric plexitis is frequent in patients with colonic diverticular disease needing surgery, and it might be implicated in the pathogenesis of the disease.

Diabetic sensory neuropathy is a common form of microvascular complication among diabetic patients. The swiftly growing population of people living with diabetes in Ethiopia and lack of elaborated scientific data on peripheral sensory neuropathy among diabetic population in Ethiopia prompted this work. This study was set out to assess the enormity and associated factors of peripheral sensory neuropathy among diabetes patients attending chronic illness clinic of Felege Hiwot Regional Referral Hospital, Bahr Dar, Northwest Ethiopia. An institution based cross-sectional study was conducted at Felege Hiwot Referral Hospital chronic illness clinic using Michigan neuropathy screening instrument tool for diabetic peripheral sensory neuropathy on 408 diabetic patients during 2016. Data were collected using interview, patient record review, anthropometric measurements and physical examination. Both bivariate and multivariate binary logistic regression was employed to identify factors associated with peripheral sensory neuropathy. Odds ratios with their 95% CI and P value less than 0.05 used to determine statistically significant associations. A total of 368 patients were included with the mean age of 49 ± 14.3 years. The overall prevalence of Peripheral Sensory Neuropathy was found to be 52.2%. The major associated factors identified by multivariate analysis were age >50 years: AOR: 3.0 CI [1.11, 7.89]; overweight and obese: AOR: 7.3 CI [3.57, 14.99]; duration of DM: AOR: 3.4 CI [1.75, 6.60]; not involved in physical exercise: AOR: 4.8 CI [1.90, 7.89]; male gender: AOR: 2.4 CI [1.18, 5.05]. Almost half of the diabetic patients who attended Felege Hiwot regional referral hospital during study period were found to present with peripheral sensory neuropathy. Socio-demographic and bio characteristics like patients age, Body Mass Index, level of physical activity and marital status were significantly associated with diabetic peripheral sensory neuropathy.

Chemotherapy-induced peripheral neuropathy (CIPN) is a common chemotherapy side effect, but its prevention and treatment remains a challenge. Neurotoxicity may lead to dose limitation or even treatment discontinuation, and therefore potentially affect the efficacy of anticancer treatment and long term outcomes. The practice to administer gabapentin for neuropathy may be applicable, but is limited by insufficient studies. The aim of our study was to assess the presence of chemotherapy-induced peripheral neuropathy in ovarian cancer patients treated with first-line paclitaxel and carboplatin chemotherapy and evaluate the effectiveness of gabapentin in treatment of this condition. 61 ovarian cancer patients treated with first line chemotherapy were included in the study. The first phase of the study was to assess neurological condition of each patient by: neuropathy symptoms scale, McGill's scale, neurological deficit and quality of life, during the chemotherapy. In the second phase of the study we evaluated the response to gabapentin treatment in a group of patients who developed neuropathy. 78.7% of the patients developed chemotherapy related neuropathy. During the course of chemotherapy these patients experienced significant exacerbation of neuropathy symptoms (p < 0.0001), neuropathic pain (p < 0.0001), neurologic deficit (p < 0.0012) and worsening of quality of life (p < 0.0002). Patients who were qualified to undergo the gabapentin treatment observed improvement in symptoms (p < 0.027), pain (p < 0.027) and neurologic deficit (p < 0.019). Quality of life did not change significantly after gabapentin treatment (p < 0.128). Chemotherapy substantially deteriorates the neurologic condition of the patients and the quality of life. Paclitaxel and carboplatin treated patients may benefit from gabapentin therapy in chemotherapy-induced peripheral neuropathy.

Psychological distress is a common problem among patients with cancer, yet it mostly goes unreported and untreated. This study examined the association of a psycho-educational intervention with the psychological distress levels of breast cancer and cervical cancer patients undergoing chemotherapy. The design of the study was quasi-experimental, pretest-posttest design with a comparison group. One hundred patients at a cancer hospital in Jakarta, Indonesia, completed Distress Thermometer screening before and after chemotherapy. Fifty patients in the intervention group were given a psycho-educational video with positive reappraisal, education and relaxation contents, while receiving chemotherapy. Patients who received the psycho-educational intervention had significantly lower distress levels compared with those in the control group. Routine distress screening, followed by distress management and outcome assessment, is needed to improve the wellbeing of cancer patients.

Peginesatide, a synthetic peptide-based erythropoiesis-stimulating agent (ESA), is a potential therapy for anemia in patients with advanced chronic kidney disease. We conducted two randomized, controlled, open-label studies (EMERALD 1 and EMERALD 2) involving patients undergoing hemodialysis. Cardiovascular safety was evaluated by analysis of an adjudicated composite safety end point--death from any cause, stroke, myocardial infarction, or serious adverse events of congestive heart failure, unstable angina, or arrhythmia--with the use of pooled data from the two EMERALD studies and two studies involving patients not undergoing dialysis. In the EMERALD studies, 1608 patients received peginesatide once monthly or continued to receive epoetin one to three times a week, with the doses adjusted as necessary to maintain a hemoglobin level between 10.0 and 12.0 g per deciliter for 52 weeks or more. The primary efficacy end point was the mean change from the baseline hemoglobin level to the mean level during the evaluation period; noninferiority was established if the lower limit of the two-sided 95% confidence interval was -1.0 g per deciliter or higher in the comparison of peginesatide with epoetin. The aim of evaluating the composite safety end point in the pooled cohort was to exclude a hazard ratio with peginesatide relative to the comparator ESA of more than 1.3. In an analysis involving 693 patients from EMERALD 1 and 725 from EMERALD 2, peginesatide was noninferior to epoetin in maintaining hemoglobin levels (mean between-group difference, -0.15 g per deciliter; 95% confidence interval [CI], -0.30 to -0.01 in EMERALD 1; and 0.10 g per deciliter; 95% CI, -0.05 to 0.26 in EMERALD 2). The hazard ratio for the composite safety end point was 1.06 (95% CI, 0.89 to 1.26) with peginesatide relative to the comparator ESA in the four pooled studies (2591 patients) and 0.95 (95% CI, 0.77 to 1.17) in the EMERALD studies.

We report a 35-year-old mulatto female patient with neurofibromatosis Type 1 who presented with facial asymmetry. The patient had two lesions: florid cemento-osseous dysplasia associated with peripheral giant cell granuloma. She was referred for surgical treatment of the peripheral giant cell granuloma and the florid cemento-osseous dysplasia was treated conservatively by a multidisciplinary team. So far, no changes have been observed in the patient's clinical status. We observed no recurrence of peripheral giant cell granuloma. To the best of our knowledge, the present case is the first report of a patient with neurofibromatosis Type 1 associated with a giant cell lesion and florid cemento-osseous dysplasia.

Variability in individual response profiles to antiplatelet therapy, in particular clopidogrel, is a well-established phenomenon. Genetic variations of the cytochrome P450 (CYP) 2C19 enzyme, a key determinant in clopidogrel metabolism, have been associated with clopidogrel response profiles. Moreover, the presence of a CYP2C19 loss-of-function allele is associated with an increased risk of atherothrombotic events among clopidogrel-treated patients undergoing percutaneous coronary interventions (PCI), prompting studies evaluating the use of genetic tests to identify patients who may be potential candidates for alternative platelet P2Y 12 receptor inhibiting therapies (prasugrel or ticagrelor). Areas covered: The present manuscript provides an overview of genetic factors associated with response profiles to platelet P2Y 12 receptor inhibitors and their clinical implications, as well as the most recent developments and future considerations on the role of genetic testing in patients undergoing PCI. Expert commentary: The availability of more user-friendly genetic tests has contributed towards the development of many ongoing clinical trials and personalized medicine programs for patients undergoing PCI. Results of pilot investigations have shown promising results, which however need to be confirmed in larger-scale studies to support the routine use of genetic testing as a strategy to personalize antiplatelet therapy and improve clinical outcomes.

Purpose: To perform a retrospective outcomes analysis of central venous catheters with peripheral venous access ports, with comparison to published data.Methods: One hundred and twelve central venous catheters with peripherally placed access ports were placed under sonographic guidance in 109 patients over a 4-year period. Ports were placed for the administration of chemotherapy, hyperalimentation, long-term antibiotic therapy, gamma-globulin therapy, and frequent blood sampling. A vein in the upper arm was accessed in each case and the catheter was passed to the superior vena cava or right atrium. Povidone iodine skin preparation was used in the first 65 port insertions. Amore » combination of Iodophor solution and povidone iodine solution was used in the last 47 port insertions. Forty patients received low-dose (1 mg) warfarin sodium beginning the day after port insertion. Three patients received higher doses of warfarin sodium for preexistent venous thrombosis. Catheter performance and complications were assessed and compared with published data.Results: Access into the basilic or brachial veins was obtained in all cases. Ports remained functional for a total of 28,936 patient days. The port functioned in 50% of patients until completion of therapy, or the patient's expiration. Ports were removed prior to completion of therapy in 18% of patients. Eleven patients (9.9% of ports placed) suffered an infectious complication (0.38 per thousand catheter-days)-in nine, at the port implantation site, in two along the catheter. In all 11 instances the port was removed. Port pocket infection in the early postoperative period occurred in three patients (4.7%) receiving a Betadine prep vs two patients (4.2%) receiving a standard O.R. prep. This difference was not statistically significant (p = 0.9). Venous thrombosis occurred in three patients (6.8%) receiving warfarin sodium and in two patients (3%) not receiving warfarin sodium. This difference was not statistically

The three main types of killer cells - CD8 + T cells, NK cells and NKT cells - have been linked to asthma and chronic obstructive pulmonary disease (COPD). However, their role in a small subset of asthma patients displaying fixed airway obstruction (FAO), similar to that seen in COPD, has not been explored. The objective of the present study was to investigate killer cell numbers, phenotype and function in peripheral blood from asthma patients with FAO, asthma patients without FAO, and healthy individuals. Peripheral CD8 + T cells (CD8 + CD3 + CD56 - ), NK cells (CD56 + CD3 - ) and NKT-like cells (CD56 + CD3 + ) of 14 asthma patients with FAO (post-bronchodilator FEV/FVC <0.7, despite clinician-optimised treatment), 7 asthma patients without FAO (post-bronchodilator FEV/FVC ≥ 0.7), and 9 healthy individuals were studied. No significant differences were seen between the number, receptor expression, MAPK signalling molecule expression, cytotoxic mediator expression, and functional cytotoxicity of peripheral killer cells from asthma patients with FAO, asthma patients without FAO and healthy individuals. Peripheral killer cell numbers or functions do not differentiate between asthma patients with or without fixed airway obstruction.

Because the islets of Langerhans are more prevalent in the body and tail of the pancreas, distal pancreatectomy (DP) is believed to increase the likelihood of developing new onset diabetes mellitus (NODM). To determine whether the development of postoperative diabetes was more prevalent in patients undergoing DP or Whipple procedure, 472 patients undergoing either a DP (n = 122) or Whipple (n = 350), regardless of underlying pathology, were analyzed at one month postoperatively. Insulin or oral hypoglycemic requirements were assessed and patients were stratified into preoperative diabetic status: NODM or preexisting diabetes. A retrospective chart review of the 472 patients between 1996 and 2014 showed that the total rate of NODM after Whipple procedure was 43 per cent, which was not different from patients undergoing DP (45%). The incidence of preoperative diabetes was 12 per cent in patients undergoing the Whipple procedure and 17 per cent in the DP cohort. Thus, the overall incidence of diabetes after Whipple procedure was 54 and 49 per cent in the DP group. The development of diabetes was unrelated to the type of resection performed. Age more than 65 and Caucasian ethnicity were associated with postoperative diabetes regardless of the type of resection performed.

We conducted this study to identify differences in the re-treatment rates and ancillary procedures for the two most commonly utilized stone treatment procedures in the Medicare population: ureteroscopy (URS) and shock wave lithotripsy (SWL). A retrospective claims analysis of the Medicare standard analytical file 5% sample was conducted to identify patients with a new diagnosis of urolithiasis undergoing treatment with URS or SWL from 2009-2010. Outcomes evaluated: (1) repeat stone removal procedures within 120 days post index procedure, (2) stent placement procedures on the index date, 30 days prior to and 120 days post index date, and (3) use of general anesthesia. We identified 3885 eligible patients, of which 2165 (56%) underwent SWL and 1720 (44%) underwent URS. Overall, SWL patients were 1.73 times more likely to undergo at least one repeat procedure than URS patients, and twice as likely to require multiple re-treatments compared to URS. Among those with ureteral stones, SWL patients were 2.27 times more likely to undergo repeat procedures. The difference was not statistically significant in renal stone patients. Overall, SWL patients were 1.41 times more likely than URS patients to have a stent placed prior to index procedure, and 1.33 times more likely to have a stent placed subsequent to the index procedure. The majority of URS patients (77.8%) had a stent placed at the time of index procedure. There was no significant difference in anesthetic approaches between SWL and URS. Patients undergoing SWL are significantly more likely to require re-treatments than URS patients. SWL patients are also significantly more likely to require ureteral stent placement as a separate event. SWL and URS patients have similar rates of general anesthesia.

Leg ischemia is a serious complication of femoral artery cannulation. The primary aim of this study was to assess the safety and efficacy of a novel bidirectional femoral arterial cannula (Sorin Group USA, a wholly owned subsidiary of LivaNova PLC, Arvada, CO USA) that provides both antegrade and retrograde flow, in patients undergoing peripheral cannulation for cardiopulmonary bypass during cardiac surgery. Patients undergoing routine cardiac surgery requiring femoral artery cannulation for cardiopulmonary bypass were identified preoperatively. Informed written consent was obtained in all cases. Bidirectional cannula insertion used either a surgical cut-down and wire through needle approach or a percutaneous technique. Flow in the superficial femoral artery was assessed using Doppler ultrasound after commencement of cardiopulmonary bypass. Lower limb perfusion was assessed using reflectance near-infrared spectroscopy to measure regional oxygen saturations in the cannulated limb during cardiopulmonary bypass. Fifteen patients (median age = 61.3 years, range = 26-79 years, 10 males, 5 females) underwent femoral arterial cannulation using the novel bidirectional femoral cannula between August 2016 and May 2017. Fourteen cannulae were inserted directly into the femoral artery via a surgical cut-down and wire through needle technique. One bidirectional cannula was inserted using a percutaneous insertion technique. Indications included minimally invasive mitral and aortic valve surgery, thoracic aortic aneurysm repair, and redo cardiac surgery. The median duration of cardiopulmonary bypass was 129 minutes (range = 53-228 minutes). The cannula was inserted and positioned without difficulty in 14 of 15 patients. Incorrect sizing and arterial spasm prevented correct cannula positioning in one patient. Antegrade flow in the superficial femoral artery was observed on Doppler ultrasound in 12 of 12 patients in which this was performed. Continuous stable distal perfusion was

Considerable studies directly connect the complications in diabetic patients, and especially peripheral neuropathy, with the emergence of depression. Neuropathetic pain may deteriorate the general health status of the diabetic patient and glycaemic regulation. The purpose of this study was to investigate the appearance and degree of diabetic peripheral neuropathy and its correlation with depression, with other parameters of the disease and also duration. 57 diabetic patients participated with diagnosed diabetic peripheral neuropathy (male n=27, female n= 30, mean of age 72.7±6.35 years). The first part of Michigan Neuropathy Screening Instrument and the Zung Depression Rating Scale were used as tools for our study. Data was analysed with the SPSS 18.0 statistic program. 57.9% of the patients were overweight, 35.1% were obese and only 7% were within normal weight range. The BMI findings between the two genders indicate that male participants are more often obese than females. Women surpassed men in the category of overweight patients (p < 0.05). The score based on MNSI was high and between 3 to 12 (mean average of 8.19±2.60 with 8 as intermediate rate). Almost 60% of patients had severe neuropathy, only 2 were found with mild symptoms and the rest had moderate neuropathtic symptoms, based on the score summary from the questionnaire. Investigating in detail the relation of diabetic neuropathy and depression, it derives that a high degree of diabetic neuropathy is related with high score of depression [F(3.160)=9.821, p=0.001]. Moderate and severe neuropathy was found with almost the same levels of depression. The correlation between diabetic neuropathy and depression is confirmed, while a very high depression rate was found in patients with severe neuropathy. The issue needs further study by using common instruments to obtain comparative results from the scientific community.

Background Diverticular disease of the colon is frequent in clinical practice, and a large number of patients each year undergo surgical procedures worldwide for their symptoms. Thus, there is a need for better knowledge of the basic pathophysiologic mechanisms of this disease entity. Objectives Because patients with colonic diverticular disease have been shown to display abnormalities of the enteric nervous system, we assessed the frequency of myenteric plexitis (i.e. the infiltration of myenteric ganglions by inflammatory cells) in patients undergoing surgery for this condition. Methods We analyzed archival resection samples from the proximal resection margins of 165 patients undergoing left hemicolectomy (60 emergency and 105 elective surgeries) for colonic diverticulitis, by histology and immunochemistry. Results Overall, plexitis was present in almost 40% of patients. It was subdivided into an eosinophilic (48%) and a lymphocytic (52%) subtype. Plexitis was more frequent in younger patients; and it was more frequent in those undergoing emergency surgery (50%), compared to elective (28%) surgery (p = 0.007). All the severe cases of plexitis displayed the lymphocytic subtype. Conclusions In conclusion, myenteric plexitis is frequent in patients with colonic diverticular disease needing surgery, and it might be implicated in the pathogenesis of the disease. PMID:26668745

The prognostic implications of dyspnea and typical angina in patients referred for coronary CT angiography have not been examined. We examined features associated with incident mortality risk among individuals undergoing coronary computed tomographic angiography (CCTA) presenting with dyspnea, typical angina, and neither of these symptoms. 1147 consecutive individuals without known CAD (mean 61 years, 61.6 %men) undergoing CCTA comprised the study population 132 with dyspnea, 218 with typical angina, and 797 without dyspnea or typical angina (reference group). Mortality risk in relation to dyspnea or typical angina was evaluated with multivariable Cox proportional hazards models compared to reference. In addition, the prognosis associated with dyspnea or typical angina was assessed among age matched subgroups. Patients with dyspnea had a greater prevalence of C70 % stenosis (p\\0.001) and coronary segments with plaque (p = 0.02) compared to the other two groups. During a follow-up of 3.1 years, 52 individuals died. By multivariable Cox models, compared to patients in reference group, dyspnea patients experienced higher mortality (HR 2.0, 95 % CI 1.0–4.0, p = 0.049) while typical angina patients did not (HR 1.1, 95 % CI 0.6–2.3, p = 0.76). In the matched group, the patients with dyspnea (HR 2.2, 95 % CI 1.1–4.3, p = 0.03) still had significantly reduced survival compared to the other two groups, while those with typical angina did not (HR 1.2, 95 % CI 0.6–2.6,p = 0.62). Dyspnea is associated with increased mortality ate compared to patients with typical angina and those with neither of these symptoms among patients undergoing CCTA.

Animal data have demonstrated increased block duration after local anaesthetic injections in diabetic rat models. Whether the same is true in humans is currently undefined. We, therefore, undertook this prospective cohort study to test the hypothesis that type-2 diabetic patients suffering from diabetic peripheral neuropathy would have increased block duration after ultrasound-guided popliteal sciatic nerve block when compared with patients without neuropathy. Thirty-three type-2 diabetic patients with neuropathy and 23 non-diabetic control patients, scheduled for fore-foot surgery, were included prospectively. All patients received an ultrasound-guided popliteal sciatic nerve block with a 30 ml 1:1 mixture of lidocaine 1% and bupivacaine 0.5%. The primary outcome was time to first opioid request after block procedure. Secondary outcomes included the time to onset of sensory blockade, and pain score at rest on postoperative day 1 (numeric rating scale 0-10). These outcomes were analysed using an accelerated failure time regression model. Patients in the diabetic peripheral neuropathy group had significantly prolonged median (IQR [range]) time to first opioid request (diabetic peripheral neuropathy group 1440 (IQR 1140-1440 [180-1440]) min vs. control group 710 (IQR 420-1200 [150-1440] min, p = 0.0004). Diabetic peripheral neuropathy patients had a time ratio of 1.57 (95%CI 1.10-2.23, p < 0.01), experienced a 59% shorter time to onset of sensory blockade (median time ratio 0.41 (95%CI 0.28-0.59), p < 0.0001) and had lower median (IQR [range]) pain scores at rest on postoperative day 1 (diabetic peripheral neuropathy group 0 (IQR 0-1 [0-5]) vs. control group 3 (IQR 0-5 [0-9]), p = 0.001). In conclusion, after an ultrasound-guided popliteal sciatic nerve block, patients with diabetic peripheral neuropathy demonstrated reduced time to onset of sensory blockade, with increased time to first opioid request when compared with patients without neuropathy. © 2018 The

Many of the patients with lymph node tuberculosis show 'Paradoxical Response" in the form of appearance of new lymph node (LN) or increase in the size of existing LN, development of new disease in other organ and worsening of the disease while on treatment. Reason behind such response in only selective patients is not clearly understood. We evaluated the pattern and predictors for paradoxical response(s) (PR) in patients with peripheral lymph node tuberculosis (TB). Study included patients aged > 6 years with peripheral lymphadenopathy of tubercular etiology attending a tertiary care hospital from Jan 2010 to Dec 2010. PR in our study was defined as worsening of pre-existing disease or development of new lesions in a patient who has been on anti-TB therapy for at least 2 weeks. One hundred ten patients with peripheral lymph node TB were included. Their mean age was 27.5 ± 5 years and 68 (62%) were females. PR occurred in 28 (25%) patients, at a mean onset time of 6 weeks (range 2-12 weeks) after starting anti-TB medication. Four of these 28 patients experienced PR on two occasions. Of these, 22 (79%) patients presented with enlarged lymph nodes only, 8 (29%) with new nodes at same or different site and 2 (7%) with discharging sinus. PR was observed more in younger age group (p> 0.05), female gender (p> 0.05), unilateral lymphadenopathy (p> 0.05) and those with positive AFB on initial examination (p< 0.01). Paradoxical response in peripheral lymph node TB is associated with younger age, female gender, unilateral lymphadenopathy and those with positive AFB on initial examination.

Evaluation of pain and degree of satisfaction in patients undergoing ultrasound-assisted peripheral regional block for the treatment of idiopathic palmar hyperhidrosis with botulinum toxin. A descriptive, observational study of patients with palmar hyperhidrosis treated with botulinum toxin A, who underwent ultrasound-guided peripheral regional block of the median and ulnar nerves with 3 ml of mepivacaine 1% in each one. The radial nerve block was injected in the anatomical snuffbox. After establishing blocking, the dermatologist performed a mapping and injected around 100 IU of botulinum toxin across the whole palm. The pain experienced during the injection of botulinum toxin was evaluated by verbal numerical scale (from 0 to 10), along with the degree of satisfaction with the anesthetic technique, and the post-anesthetic complications. A total of 40 patients were enrolled in the study, 11 men and 29 women with no significant differences. The pain intensity assessed with verbal numerical scale was 1.03 (standard deviation of 1.37). No patients had a value greater than 5. The degree of patient satisfaction with the anesthetic technique was very good for 85% of the patients, and good for 7.5%. There were no complications related to type of anesthesia. The ultrasound-assisted peripheral regional block could be a simple, effective and safe technique for patients undergoing palmar injection of botulinum toxin. Pain intensity was very low, and it provided a very good level of satisfaction in most patients. Copyright © 2013 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.

The purposes of this study were to document the prevalence and severity of coexisting lumbar spondylosis in patients with advanced knee OA undergoing TKA and to determine whether the coexisting lumbar spondylosis at the time of TKA adversely affects clinical scores in affected patients before and 2 years after TKA. Radiographic lumbar spine degeneration and lumbar spine symptoms including lower back pain, radiating pain at rest, and radiating pain with activity were assessed in 225 patients undergoing TKA. In addition, the WOMAC score and the SF-36 scores were evaluated before and 2 years after TKA. Potential associations of radiographic lumbar spine degeneration and lumbar spine symptom severities with pre- and postoperative WOMAC subscales and SF-36 scores were examined. All 225 patients had radiographic degeneration of the lumbar spine, and the large majority (89% [200 of 225]) had either moderate or severe spondylosis (72% and 17%, respectively). A total of 114 patients (51%) had at least one moderate or severe lumbar spine symptom. No association was found between radiographic severity of lumbar spine degeneration and pre- and postoperative clinical scores. In terms of lumbar spine symptoms, more severe symptoms were likely to adversely affect the preoperative WOMAC and SF-36 physical component summary (PCS) scores, but most of these adverse effects improved by 2 years after TKA with the exception of the association between severe radiating pain during activity and a poorer postoperative SF-36 PCS score (regression coefficient = -5.41, p = 0.015). Radiographic lumbar spine degeneration and lumbar spine symptoms are common among patients with advanced knee OA undergoing TKA. Severe lumbar spine symptoms

Current evidence suggests that gut dysbiosis drives obesity and non-alcoholic fatty liver disease (NAFLD) pathogenesis. Toll-like receptor 2 (TLR2) and TLR6 specifically recognize components of Gram-positive bacteria. Despite the potential implications of TLR2 in NAFLD pathogenesis, the role of TLR6 has not been addressed. Our aim is to study a potential role of TLR6 in obesity-related NAFLD. Forty morbidly obese patients undergoing bariatric surgery were prospectively studied. Cell surface expression of TLR2 and TLR6 was assessed on peripheral blood mononuclear cells (PBMCs) by flow cytometry. Freshly isolated monocytes were cultured with specific TLR2/TLR6 agonists and intracellular production of cytokines was determined by flow-cytometry. In liver biopsies, the expression of TLR2 and TLR6 was analyzed by immunohistochemistry and cytokine gene expression using RT-qPCR. TLR6 expression in PBMCs from non-alcoholic steatohepatitis (NASH) patients was significantly higher when compared to those from simple steatosis. The production of pro-inflammatory cytokines in response to TLR2/TLR6 stimulation was also significantly higher in patients with lobular inflammation. Hepatocyte expression of TLR6 but not that of TLR2 was increased in NAFLD patients compared to normal liver histology. Deregulated expression and activity of peripheral TLR6 in morbidly obese patients can mirror the liver inflammatory events that are well known drivers of obesity-related NASH pathogenesis. Moreover, TLR6 is also significantly overexpressed in the hepatocytes of NAFLD patients compared to their normal counterparts. Thus, deregulated TLR6 expression may potentiate TLR2-mediated liver inflammation in NAFLD pathogenesis, and also serve as a potential peripheral biomarker of obesity-related NASH.

Reduction of cognitive function is a possible side effect after the use of cardiopulmonary bypass (CPB) during cardiac surgery. Since it has been proven that piracetam is cerebroprotective in patients undergoing coronary bypass surgery, we investigated the effects of piracetam on the cognitive performance of patients undergoing open heart surgery. Patients scheduled for elective open heart surgery were randomized to the piracetam or placebo group in a double-blind study. Patients received 12 g of piracetam or placebo at the beginning of the operation. Six neuropsychological subtests from the Syndrom Kurz Test and the Alzheimer's Disease Assessment Scale were performed preoperatively and on day 3, postoperatively. To assess the overall cognitive function and the degree of cognitive decline across all tests after the surgery, we combined the six test-scores by principal component analysis. A total of 88 patients with a mean age of 67 years were enrolled into the study. The mean duration of CPB was 110 minutes. Preoperative clinical parameters and overall cognitive functions were not significantly different between the groups. The postoperative combined score of the neuropsychological tests showed deterioration of cognitive function in both groups (piracetam: preoperative 0.19 ± 0.97 vs. postoperative -0.97 ± 1.38, p <0.0005 and placebo: preoperative -0.14 ± 0.98 vs. postoperative -1.35 ± 1.23, p <0.0005). Patients taking piracetam did not perform better than those taking placebo, and both groups had the same decline of overall cognitive function (p = 0.955). Piracetam had no cerebroprotective effect in patients undergoing open heart surgery. Unlike the patients who underwent coronary surgery, piracetam did not reduce the early postoperative decline of neuropsychological abilities in heart valve patients.

Eribulin is a microtubule inhibitor, which is approved for the treatment of breast cancer. Peripheral neuropathy has been reported in the studies of eribulin, but the incidence and relative risk (RR) of eribulin-associated peripheral neuropathy varied greatly in cancer patients. The purpose of this meta-analysis was to determine the overall incidence and RR of eribulin-associated peripheral neuropathy in cancer patients. Pubmed database and Embase and abstracts presented at the American Society of Clinical Oncology (ASCO) meetings were systematically reviewed for primary studies. Eligible studies included prospective clinical trials and expanded access programs of cancer patients treated with eribulin. Statistical analyses were performed to calculate the incidences, RRs, and 95% confidence intervals (CIs). Altogether, 4,849 patients from 19 clinical trials were selected for this meta-analysis. The incidences of all-grade and high-grade peripheral neuropathy were 27.5% (95% CI: 23.3-32.4%) and 4.7% (95% CI: 3.6-6.2%), respectively. The relative risks of peripheral neuropathy of eribulin compared to control were increased for all-grade (RR = 1.89, 95% CI: 1.10-3.25) but not statistically significant for high-grade (RR = 2.98, 95% CI: 0.71-12.42). The use of eribulin is associated with an increased incidence of peripheral neuropathy. The RR is increased for all-grade peripheral neuropathy.

To investigate lower limb biomechanical strategy during stair walking in patients with diabetes and patients with diabetic peripheral neuropathy, a population known to exhibit lower limb muscular weakness. The peak lower limb joint moments of twenty-two patients with diabetic peripheral neuropathy and thirty-nine patients with diabetes and no neuropathy were compared during ascent and descent of a staircase to thirty-two healthy controls. Fifty-nine of the ninety-four participants also performed assessment of their maximum isokinetic ankle and knee joint moment (muscle strength) to assess the level of peak joint moments during the stair task relative to their maximal joint moment-generating capabilities (operating strengths). Both patient groups ascended and descended stairs slower than controls (p<0.05). Peak joint moments in patients with diabetic peripheral neuropathy were lower (p<0.05) at the ankle and knee during stair ascent, and knee only during stair descent compared to controls. Ankle and knee muscle strength values were lower (p<0.05) in patients with diabetic peripheral neuropathy compared to controls, and lower at knee only in patients without neuropathy. Operating strengths were higher (p<0.05) at the ankle and knee in patients with neuropathy during stair descent compared to the controls, but not during stair ascent. Patients with diabetic peripheral neuropathy walk slower to alter gait strategy during stair walking and account for lower-limb muscular weakness, but still exhibit heightened operating strengths during stair descent, which may impact upon fatigue and the ability to recover a safe stance following postural instability.

Introduction Variability in individual response profiles to antiplatelet therapy, in particular clopidogrel, is a well-established phenomenon. Genetic variations of the cytochrome P450 (CYP) 2C19 enzyme, a key determinant in clopidogrel metabolism, have been associated with clopidogrel response profiles. Moreover, the presence of a CYP2C19 loss-of-function allele is associated with an increased risk of atherothrombotic events among clopidogrel-treated patients undergoing percutaneous coronary interventions (PCI), prompting studies evaluating the use of genetic tests to identify patients who may be potential candidates for alternative platelet P2Y12 receptor inhibiting therapies (prasugrel or ticagrelor). Areas covered The present manuscript provides an overview of genetic factors associated with response profiles to platelet P2Y12 receptor inhibitors and their clinical implications, as well as the most recent developments and future considerations on the role of genetic testing in patients undergoing PCI. Expert Commentary The availability of more user-friendly genetic tests has contributed towards the development of many ongoing clinical trials and personalized medicine programs for patients undergoing PCI. Results of pilot investigations have shown promising results, which however need to be confirmed in larger-scale studies to support the routine use of genetic testing as a strategy to personalize antiplatelet therapy and improve clinical outcomes.

The relative benefit of higher statin dosing in patients with peripheral artery disease has not been reported previously. We compared the effectiveness of low- or moderate-intensity (LMI) versus high-intensity (HI) statin dose on clinical outcomes in patients with peripheral artery disease. We reviewed patients with symptomatic peripheral artery disease who underwent peripheral angiography and/or endovascular intervention from 2006 to 2013 who were not taking other lipid-lowering medications. HI statin use was defined as atorvastatin 40-80 mg or rosuvastatin 20-40 mg. Baseline demographics, procedural data, and outcomes were retrospectively analyzed. Among 909 patients, 629 (69%) were prescribed statins, and 124 (13.6%) were treated with HI statin therapy. Mean low-density lipoprotein level was similar in patients on LMI versus HI (80±30 versus 87±44 mg/dL, P =0.14). Demographics including age (68±12 versus 67±10 years, P =0.25), smoking history (76% versus 80%, P =0.42), diabetes mellitus (54% versus 48%, P =0.17), and hypertension (88% versus 89%, P =0.78) were similar between groups (LMI versus HI). There was a higher prevalence of coronary artery disease (56% versus 75%, P =0.0001) among patients on HI statin (versus LMI). After propensity weighting, HI statin therapy was associated with improved survival (hazard ratio for mortality: 0.52; 95% confidence interval, 0.33-0.81; P =0.004) and decreased major adverse cardiovascular events (hazard ratio: 0.58; 95% confidence interval 0.37-0.92, P =0.02). In patients with peripheral artery disease who were referred for peripheral angiography or endovascular intervention, HI statin therapy was associated with improved survival and fewer major adverse cardiovascular events compared with LMI statin therapy. © 2017 The Authors.

Retrospective database analysis. To investigate incidence, comorbidities, and impact on health care resources of Clostridium difficile infection after lumbar spine surgery. C. difficile colitis is reportedly increasing in hospitalized patients and can have a negative impact on patient outcomes. No data exist on estimates of C. difficile infection rates and its consequences on patient outcomes and health care resources among patients undergoing lumbar spine surgery. The Nationwide Inpatient Sample was examined from 2002 to 2011. Patients were included for study based on International Classification of Diseases, Ninth Revision, Clinical Modification, procedural codes for lumbar spine surgery for degenerative diagnoses. Baseline patient characteristics were determined and multivariable analyses assessed factors associated with increased incidence of C. difficile and risk of mortality. The incidence of C. difficile infection in patients undergoing lumbar spine surgery is 0.11%. At baseline, patients infected with C. difficile were significantly older (65.4 yr vs. 58.9 yr, P<0.0001) and more likely to have diabetes with chronic complications, neurological complications, congestive heart failure, pulmonary disorders, coagulopathy, and renal failure. Lumbar fusion (P=0.0001) and lumbar fusion revision (P=0.0003) were associated with increased odds of postoperative infection. Small hospital size was associated with decreased odds (odds ratio [OR], 0.5; P<0.001), whereas urban hospitals were associated with increased odds (OR, 2.14; P<0.14) of acquiring infection. Uninsured (OR, 1.62; P<0.0001) and patients with Medicaid (OR, 1.33; P<0.0001) were associated with higher odds of acquiring postoperative infection. C. difficile increased hospital length of stay by 8 days (P<0.0001), hospital charges by 2-fold (P<0.0001), and inpatient mortality to 4% from 0.11% (P<0.0001). C. difficile infection after lumbar spine surgery carries a 36.4-fold increase in mortality and costs

This study was conducted in order to determine the effects of body position on electromyographic (EMG) activity of sternocleidomastoid and masseter muscles, in 15 patients with myogenic cranio-cervical-mandibular dysfunction undergoing occlusal splint therapy. EMG activity was recorded by placing surface electrodes on the sternocleidomastoid and masseter muscles (contralateral to the habitual sleeping side of each patient). EMG activity at rest and during swallowing of saliva and maximal voluntary clenching was recorded in the following body positions: standing, supine and lateral decubitus. In the sternocleidomastoid muscle significant higher EMG activities at rest and during swallowing were recorded in the lateral decubitus position, whereas during maximal voluntary clenching EMG activity did not change. In the masseter muscle significant higher EMG activity during maximal voluntary clenching in a standing position was observed, whereas EMG activity at rest and during swallowing did not change. The opposite pattern of EMG activity supports the idea that there may exist a differential modulation of the motor neuron pools of the sternocleidomastoid and masseter muscles, of peripheral and/or central origin. This suggests that the presence of parafunctional habits and body position could be closely correlated with the clinical symptomatology in these muscles in patients with myogenic craniomandibular dysfunction.

Cardiovascular disease is a major cause of mortality in hemodialysis patients. The aim was to assess the relationship of various invasive cardiovascular procedures (ICP) to clinical outcome in hemodialysis patients. A total of 5,813 patients at 76 facilities were on maintenance hemodialysis in Kumamoto Prefecture. Of these, 4,807 patients at 58 institutions were enrolled. Of 4,807 patients, 212 ICP (4.4%) were performed for various cardiovascular diseases in 189 patients (3.9%). ICP included PCI (n=80), endovascular treatment (n=59), radiofrequency catheter ablation (n=8), implantation of permanent pacemaker (n=15) and ICD (n=5), thoracotomy for valvular diseases (n=16), CABG (n=14), bypass surgery for peripheral artery disease (PAD; n=8), and artificial vessel replacement for aneurysm or aortic dissection (n=7). The overall mortality rate was 10.1% (19/189 patients). The mortality rate was highest in patients who underwent ICP for PAD, compared with other ICP (PAD, 18.2%; non-PAD, 6.7%, P=0.017). Infection and PAD were significant predictors of mortality (infection: OR, 8.30; 95% CI: 1.29-65.13, P=0.027; PAD: OR, 3.76; 95% CI: 1.35-10.48, P=0.012). The presence of inflammation/malnutrition factors was associated with high mortality (OR, 15.49; 95% CI: 3.22-74.12, P=0.0006). In this community-based registry study of 4,807 hemodialysis patients, the mortality rate of PAD patients was high despite ICP.

Previous studies have indicated that music decreases intraoperative sedative requirements in patients undergoing surgical procedures under regional anesthesia. In this study we sought to determine whether this decrease in sedative requirements results from music or from eliminating operating room (OR) noise. A secondary aim of the study was to examine the relationship of response to intraoperative music and participants' culture (i.e., American versus Lebanese). Eighty adults (36 American and 54 Lebanese) undergoing urological procedures with spinal anesthesia and patient-controlled IV propofol sedation were randomly assigned to intraoperative music, white noise, or OR noise. We found that, controlling for ambient OR noise, intraoperative music decreases propofol requirements (0.004 +/- 0.002 mg . kg(-1) . min(-1) versus 0.014 +/- 0.004 mg . kg(-1) . min(-1) versus 0.012 +/- 0.002 mg . kg(-1) . min(-1); P = 0.026). We also found that, regardless of group assignment, Lebanese patients used less propofol as compared with American patients (0.005 +/- 0.001 mg . kg(-1) . min(-1) versus 0.017 +/- 0.003 mg . kg(-1) . min(-1); P = 0.001) and that, in both sites, patients in the music group required less propofol (P < 0.05). We conclude that when controlling for ambient OR noise, intraoperative music decreases propofol requirements of both Lebanese and American patients who undergo urological surgery under spinal anesthesia.

Clinical predictors of perioperative mortality in geriatric patients undergoing emergent general surgery have not been well described. The purpose of this study was to determine the incidence of postoperative morbidity and mortality in geriatric patients and factors associated with mortality. A retrospective review of patients 65 years of age or older undergoing emergent general surgery at a public teaching hospital was performed over a 7-year period. Data collected included demographics, comorbidities, laboratory studies, perioperative morbidities, and mortality. Descriptive statistics and predictors of morbidity and mortality are described. The mean age was 74 years. Indications for surgery included small bowel obstruction (24%), diverticulitis (20%), perforated viscous (16%), and large bowel obstruction (9%). The overall complication rate was 41 per cent with six cardiac complications (14%) and seven perioperative (16%) deaths. Mean admission serum creatinine was significantly higher in patients who died (3.6 vs 1.5 mg/dL, P = 0.004). Mortality for patients with an admission serum creatinine greater than 2.0 mg/dL was 42 per cent (5 of 12) compared with 3 per cent (2 of 32) for those 2.0 mg/dL or less (OR, 10.7; CI, 1.7 to 67; P = 0.01). Morbidity and mortality in geriatric patients undergoing emergency surgery remains high with the most significant predictor of mortality being the presence of renal insufficiency on admission.

Patients undergoing hemodialysis have a higher rate of hepatitis C virus infection than the general population, and due to various factors including hemodialysis and immunosuppression, it is difficult to make a diagnosis. The appearance of direct-acting antiviral agents greatly promotes the treatment of hepatitis C, but there are still no adequate data on their effect and safety in patients undergoing hemodialysis. This article discusses the prevalence, diagnosis, and treatment of hepatitis C in patients undergoing hemodialysis.

Methicillin-resistant Staphylococcus aureus is a leading cause of death in patients undergoing hemodialysis. However, controversy exists about the optimal dose of vancomycin that will yield the recommended pre-hemodialysis serum concentration of 15-20 mg/L. To develop a data-driven model to optimize the accuracy of maintenance dosing of vancomycin for patients undergoing hemodialysis. A prospective observational cohort study was performed with 164 observations obtained from a convenience sample of 63 patients undergoing hemodialysis. All vancomycin doses were given on the floor after completion of a hemodialysis session. Multivariate linear generalized estimating equation analysis was used to examine independent predictors of pre-hemodialysis serum vancomycin concentration. Pre-hemodialysis serum vancomycin concentration was independently associated with maintenance dose ( B = 0.658, p < 0.001), baseline pre-hemodialysis serum concentration of the drug ( B = 0.492, p < 0.001), and interdialytic interval ( B = -2.133, p < 0.001). According to the best of 4 models that were developed, the maintenance dose of vancomycin required to achieve a pre-hemodialysis serum concentration of 15-20 mg/L, if the baseline serum concentration of the drug was also 15-20 mg/L, was 5.9 mg/kg with interdialytic interval of 48 h and 7.1 mg/kg with interdialytic interval of 72 h. However, if the baseline pre-hemodialysis serum concentration was 10-14.99 mg/L, the required dose increased to 9.2 mg/kg with an interdialytic interval of 48 h and 10.0 mg/kg with an interdialytic interval of 72 h. The maintenance dose of vancomycin varied according to baseline pre-hemodialysis serum concentration of the drug and interdialytic interval. The current practice of targeting a pre-hemodialysis concentration of 15-20 mg/L may be difficult to achieve for the majority of patients undergoing hemodialysis.

The hypothesis that exercise-induced myocardial ischemia is associated with abnormal platelet activation and fibrin formation or dissolution was tested in patients with coronary artery disease undergoing upright bicycle stress testing. In vivo platelet activation was assessed by radioimmunoassay of platelet factor 4, beta-thrombo-globulin and thromboxane B2. In vivo fibrin formation was assessed by radioimmunoassay of fibrinopeptide A, and fibrinolysis was assessed by radioimmunoassay of thrombin-increasable fibrinopeptide B which reflects plasmin cleavage of fibrin I. Peripheral venous concentrations of these substances were measured in 10 normal subjects and 13 patients with coronary artery disease at rest and during symptom-limited peak exercise. Platelet factor 4, beta-thromboglobulin and thromboxane B2 concentrations were correlated with rest and exercise catecholamine concentrations to determine if exercise-induced elevation of norepinephrine and epinephrine enhances platelet activation. Left ventricular end-diastolic and end-systolic volumes, ejection fraction and segmental wall motion were measured at rest and during peak exercise by first pass radionuclide angiography. All patients with coronary artery disease had documented exercise-induced myocardial ischemia manifested by angina pectoris, ischemic electrocardiographic changes, left ventricular segmental dyssynergy and a reduction in ejection fraction. Rest and peak exercise plasma concentrations were not significantly different for platelet factor 4, beta-thromboglobulin, thromboxane B2, fibrinopeptide A and thrombin-increasable fibrinopeptide B. Peripheral venous concentrations of norepinephrine and epinephrine increased significantly (p less than 0.001) in both groups of patients. The elevated catecholamine levels did not lead to detectable platelet activation. This study demonstrates that enhanced platelet activation, thromboxane release and fibrin formation or dissolution are not detectable in

Objective: to evaluate the self-esteem of cancer patients undergoing chemotherapy. Method: descriptive analytical cross-sectional study with a quantitative approach. Around 156 patients that attended an oncology unit of a mid-sized hospital participated in the study. Results: we found a higher frequency of patients with high self-esteem, but some of them showed average or low self-esteem. The scale showed a Cronbach's alpha value of 0.746, by considering its acceptable internal consistency for the evaluated items. No independent variables showed significant associations with self-esteem. Conclusion: the cancer patients evaluated have presented high self-esteem; thus, it becomes crucial for nursing to plan the assistance of patients undergoing chemotherapy treatments, which enables actions and strategies that meet their physical and psychosocial conditions, aiming to maintain and rehabilitate these people's emotional aspects.

Peripheral nerve block combined with general anesthesia is a preferable anesthesia method for elderly patients receiving hip arthroplasty. The depth of sedation may influence patient recovery. Therefore, we investigated the influence of peripheral nerve blockade and different intraoperative sedation levels on the short-term recovery of elderly patients receiving total hip arthroplasty. Patients aged 65 years and older undergoing total hip arthroplasty were randomized into 3 groups: a general anesthesia without lumbosacral plexus block group, and 2 general anesthesia plus lumbosacral plexus block groups, each with a different level of sedation (light or deep). The extubation time and intraoperative consumption of propofol, sufentanil, and vasoactive agent were recorded. Postoperative delirium and early postoperative cognitive dysfunction were assessed using the Confusion Assessment Method and Mini-Mental State Examination, respectively. Postoperative analgesia was assessed by the consumption of patient-controlled analgesics and visual analog scale scores. Discharge time and complications over a 30-day period were also recorded. Lumbosacral plexus block reduced opioid intake. With lumbosacral plexus block, intraoperative deep sedation was associated with greater intake of propofol and vasoactive agent. In contrast, patients with lumbosacral plexus block and intraoperative light sedation had lower incidences of postoperative delirium and postoperative cognitive decline, and earlier discharge readiness times. The 3 groups showed no difference in complications within 30 days of surgery. Lumbosacral plexus block reduced the need for opioids and offered satisfactory postoperative analgesia. It led to better postoperative outcomes in combination with intraoperative light sedation (high bispectral index).

The authors determined the pharmacokinetics of fentanyl 100 micrograms X kg-1 iv in patients undergoing elective abdominal aortic surgery. The mean (+/- SD) age of the ten patients was 67.2 +/- 8.7 yr; their mean weight was 78.5 +/- 13.7 kg. Seven patients had aortic aneurysm repair, and the other three patients had aortobifemoral grafts. Serum fentanyl concentrations were determined from samples drawn at increasing intervals over a 24-h period. A three-compartment pharmacokinetic model was fit to the concentration versus time data. Total drug clearance was 9.8 +/- 1.8 ml X min-1 X kg-1. The volume of distribution at steady-state (Vdss) was 5.4 +/- 1.9 X 1 kg-1. Elimination half-time was 8.7 +/- 2.5 h. There were no significant correlations between these pharmacokinetic parameters and patient's age, duration of aortic cross-clamping, duration of surgery, intraoperative blood loss, or volume of iv fluids given intraoperatively. In healthy volunteers or patients undergoing general surgery, other investigators report mean elimination half-times for fentanyl ranging from 1.7 to 4.4 h. The prolonged elimination half-time in patients having abdominal aortic surgery has important clinical implications. In particular, recovery from large doses will take much longer than would have been anticipated from previously published fentanyl pharmacokinetic data.

This study was an exploratory repeated measures design comparing patients undergoing two magnitudes of surgery in the lumbar spine: lumbar herniated disc repair and posterior lumbar fusion. The present study evaluated and compared the effect of perceived pain, perceived stress, anxiety, and mood on natural killer cell activity (NKCA) and IL-6 production among adult patients undergoing lumbar surgery. Presurgical stress and anxiety can lead to detrimental patient outcomes after surgery, such as increased infection rates. It has been hypothesized that such outcomes are due to stress-immune alterations, which may be further exacerbated by the extent of surgery. However, psychologic stress, anxiety, and mood have not been previously characterized in patients undergoing spinal surgery. Pain, stress, anxiety, and mood were measured using self-report instruments at T1 (1 week before surgery), T2 (the day of surgery), T3 (the day after surgery), and T4 (6 weeks after surgery). Blood (30 mL) was collected for immune assessments at each time point. Pain, stress, anxiety, and mood state were elevated at baseline in both surgical groups and were associated with significant reduction in NKCA compared with the nonsurgical control group. A further decrease in NKCA was observed 24 hours after surgery in both surgical groups with a significant rise in stimulated IL-6 production, regardless of the magnitude of surgery. In the recovery period, NKCA increased to or above baseline values, which correlated with decreased levels of reported pain, perceived stress, anxiety, and mood state. This study demonstrated that patients undergoing elective spinal surgery are highly stressed and anxious, regardless of the magnitude of surgery and that such psychologic factors may mediate a reduction in NKCA.

Background Schistosomiasis is a helminthic disease that affects more than 200 million people. An effective vaccine would be a major step towards eliminating the disease. Studies suggest that T follicular helper (Tfh) cells provide help to B cells to generate the long-term humoral immunity, which would be a crucial component of successful vaccines. Thus, understanding the biological characteristics of Tfh cells in patients with schistosomiasis, which has never been explored, is essential for vaccine design. Methodology/Principal Findings In this study, we investigated the biological characteristics of peripheral memory Tfh cells in schistosomiasis patients by flow cytometry. Our data showed that the frequencies of total and activated peripheral memory Tfh cells in patients were significantly increased during Schistosoma japonicum infection. Moreover, Tfh2 cells, which were reported to be a specific subpopulation to facilitate the generation of protective antibodies, were increased more greatly than other subpopulations of total peripheral memory Tfh cells in patients with schistosomiasis japonica. More importantly, our result showed significant correlations of the percentage of Tfh2 cells with both the frequency of plasma cells and the level of IgG antibody. In addition, our results showed that the percentage of T follicular regulatory (Tfr) cells was also increased in patients with schistosomiasis. Conclusions/Significance Our report is the first characterization of peripheral memory Tfh cells in schistosomasis patients, which not only provides potential targets to improve immune response to vaccination, but also is important for the development of vaccination strategies to control schistosomiasis.

Regulation of coronary vasomotor tone by serotonin is significantly changed after cardioplegic arrest and reperfusion. The current study investigates whether cardiopulmonary bypass may also affect peripheral arteriolar response to serotonin in patients with or without diabetes. Human peripheral microvessels (90-180 µm diameter) were dissected from harvested skeletal muscle tissues from diabetic and non-diabetic patients before and after cardiopulmonary bypass and cardiac surgery (n = 8/group). In vitro contractile response to serotonin was assessed by videomicroscopy in the presence or absence of serotonin alone (10 -9 -10 -5 M) or combined with the selective serotonin 1B receptor (5-HT1B) antagonist, SB224289 (10 -6 M). 5-HT1A/1B protein expression in the skeletal muscle was measured by Western-blot and immunohistochemistry. There were no significant differences in contractile response of peripheral arterioles to serotonin (10 -5 M) pre-cardiopulmonary bypass between diabetic and non-diabetic patients. After cardiopulmonary bypass, contractile response to serotonin was significantly impaired in both diabetic and non-diabetic patients compared to their pre-cardiopulmonary bypass counterparts (P < .05). This effect was more pronounced in diabetic patients than non-diabetic patients (P < .05 versus non-diabetic). The contractile response to serotonin was significantly inhibited by the 5-HT1B antagonist in both diabetic and non-diabetic vessels (P < .05 versus serotonin alone). There were no significant differences in the expression/distribution of 5-HT1A/1B between non-diabetic and diabetic groups or between pre- versus post- cardiopulmonary bypass vessels. Cardiopulmonary bypass is associated with decreased contractile response of peripheral arterioles to serotonin and this effect was exaggerated in the presence of diabetes. Serotonin-induced contractile response of the peripheral arterioles was via 5-HT1B in both diabetic and non-diabetic patients. Copyright �

Nab-paclitaxel, a Cremophor EL-free formulation of paclitaxel, is used to treat various malignancies. Peripheral neuropathy is one of its major toxicities, although the overall incidence remains unclear. We performed a meta-analysis to calculate the incidence of peripheral neuropathy in cancer patients treated with nab-paclitaxel and to compare the relative risk (RR) with conventional taxanes. The electronic databases were searched for relevant clinical trials. Eligible studies included phase II and III prospective clinical trials of cancer patients treated with nab-paclitaxel with toxicity profile on peripheral neuropathy. Statistical analyses were done to calculate summary incidences, RRs and 95% confidence intervals (CI), using fixed-effects or random-effects models based on the heterogeneity of the included studies. Nineteen trials were selected for the meta-analysis, yielding a total of 2878 cancer patients. The overall incidences of peripheral neuropathy (all-grade) was 51.0% (95% CI: 45.1-57.6%), and that of high-grade peripheral neuropathy was 12.4% (9.8-15.7%). The RRs of peripheral neuropathy of nab-paclitaxel compared to taxanes were not increased for all-grade and high-grade peripheral neuropathy. Nab-paclitaxel is associated with an increased risk of developing peripheral neuropathy. Future clinical studies are still needed to investigate the risk reduction and possible use of nab-paclitaxel. © 2015 John Wiley & Sons Ltd.

Morbidity and mortality caused by schistosomiasis usually results from immunopathology. But the underlying mechanisms are not yet clearly understood. Th2-type immune response is thought to be dominant during chronic schistosomiasis, and upregulation of arginase-I is one component of this milieu. A cohort study was conducted to assess arginase activity in peripheral blood of humans with intestinal schistosomiasis in Wonji-Shoa Sugar Estate, Central Ethiopia. Laboratory-confirmed 30 Schistosoma mansoni-infected patients and 18 apparently healthy controls were recruited. Faecal egg count was carried out by Kato-Katz technique. Plasma and peripheral blood mononuclear cells (PBMCs) were isolated from whole blood. Activity of arginase in plasma and PBMC lysates was measured, and results were compared with that of controls. Twenty-one of 30 patients had light infection, whereas moderate and heavy intensity infections were observed in eight and only one patient(s), respectively. A significant increase in both PBMC (patients: 59.96 + 82.99, controls: 25.44 + 24.6 mU/mg protein, P < 0.0001) and plasma (patients: 1.61 + 2.19, controls: 0.31 + 0.73 mU/mL plasma, P < 0.0001) arginase activity was observed during human S. mansoni infection. Arginase activity increases in peripheral blood of patients with intestinal schistosomiasis. © 2015 John Wiley & Sons Ltd.

Chemotherapy-induced peripheral neuropathies (CIPNs) are an increasingly common neuropathic and pain syndrome in adult and pediatric cancer patients and survivors [1–69]. However, symptoms associated with CIPNs are often undiagnosed, under-assessed, and communications problems between clinicians, family members, and patients have been observed [70–73]. Less is known about the prevalence and impact of CIPNs on pediatric cancer populations [70–71]. This article aims to provide a brief understanding of CIPNs in pediatric populations, and to review the evidence for both its prevention and treatment. PMID:25144779

Numerous studies have been published on comorbid anxiety and depression in patients with vertigo. However, very few studies have separately described and analyzed anxiety or depression in patients with different types of vestibular peripheral vertigo. The present study investigated anxiety and depression among patients with 4 different types of peripheral vertigo. A total of 129 patients with 4 types of peripheral vertigo, namely, benign paroxysmal positional vertigo (BPPV, n = 49), migrainous vertigo (MV, n = 37), Menière disease (MD, n = 28), and vestibular neuritis (VN, n = 15), were included in the present study. Otological and neurootological examinations were carefully performed, and self-rating anxiety scale and self-rating depression scale were used to evaluate anxiety and depression. Patients were divided into 2 groups, according to the vestibular function: normal and abnormal vestibular function. There was no significant difference in the risk of anxiety/depression between these 2 groups. However, for patients with the 4 different vertigo types, the prevalence of anxiety (MV = 45.9%, MD = 50%) and depression (MV = 27%, MD = 28.6%) was significantly higher in the patients with MV or MD than those with BPPV or VN (P < 0.05). Vestibular function is not significantly associated with the risk of anxiety/depression. Anxiety/depression is more common in patients with MV or MD than those with BPPV or VN. This may be due to the different mechanisms involved in these 4 types of vertigo, as well as differences in the prevention and self-control of the patients against the vertigo.

Background Eribulin is a microtubule inhibitor, which is approved for the treatment of breast cancer. Peripheral neuropathy has been reported in the studies of eribulin, but the incidence and relative risk (RR) of eribulin-associated peripheral neuropathy varied greatly in cancer patients. The purpose of this meta-analysis was to determine the overall incidence and RR of eribulin-associated peripheral neuropathy in cancer patients. Materials and Methods Pubmed database and Embase and abstracts presented at the American Society of Clinical Oncology (ASCO) meetings were systematically reviewed for primary studies. Eligible studies included prospective clinical trials and expanded access programs of cancer patients treated with eribulin. Statistical analyses were performed to calculate the incidences, RRs, and 95% confidence intervals (CIs). Results Altogether, 4,849 patients from 19 clinical trials were selected for this meta-analysis. The incidences of all-grade and high-grade peripheral neuropathy were 27.5% (95% CI: 23.3–32.4%) and 4.7% (95% CI: 3.6–6.2%), respectively. The relative risks of peripheral neuropathy of eribulin compared to control were increased for all-grade (RR = 1.89, 95% CI: 1.10–3.25) but not statistically significant for high-grade (RR = 2.98, 95% CI: 0.71–12.42). Conclusions The use of eribulin is associated with an increased incidence of peripheral neuropathy. The RR is increased for all-grade peripheral neuropathy. PMID:29340112

Reclaiming the Periphery: Automated Kinetic Perimetry for Measuring Peripheral Visual Fields in Patients With Glaucoma.

Peripheral vision is important for mobility, balance, and guidance of attention, but standard perimetry examines only <20% of the entire visual field. We report on the relation between central and peripheral visual field damage, and on retest variability, with a simple approach for automated kinetic perimetry (AKP) of the peripheral field. Thirty patients with glaucoma (median age 68, range 59-83 years; median Mean Deviation -8.0, range -16.3-0.1 dB) performed AKP and static automated perimetry (SAP) (German Adaptive Threshold Estimation strategy, 24-2 test). Automated kinetic perimetry consisted of a fully automated measurement of a single isopter (III.1.e). Central and peripheral visual fields were measured twice on the same day. Peripheral and central visual fields were only moderately related (Spearman's ρ, 0.51). Approximately 90% of test-retest differences in mean isopter radius were < ±4 deg. Relative to the range of measurements in this sample, the retest variability of AKP was similar to that of SAP. Patients with similar central visual field loss can have strikingly different peripheral visual fields, and therefore measuring the peripheral visual field may add clinically valuable information.

Contemporary data on patients presenting with acute limb ischemia (ALI), who are selected for treatment with endovascular peripheral vascular interventions (PVI), are limited. Our study examined outcomes following endovascular PVI in patients with ALI by comparing with patients treated for chronic critical limb ischemia using a regional quality improvement registry. Of the 11 035 patients in the Vascular Study Group of New England PVI database (2010-2014), we identified 365 patients treated for lower extremity ALI who were 5:1 frequency matched (by procedure year and arterial segments treated) to 1808 patients treated for critical limb ischemia. ALI patients treated with PVI had high burden of atherosclerotic risk factors and were more likely to have had prior ipsilateral revascularizations. ALI patients were less likely to be treated with self-expanding stents and more likely to undergo thrombolysis than patients with critical limb ischemia. In multivariable analysis, ALI was associated with higher technical failure (odds ratio 1.7, 95% confidence interval, 1.1%-2.5%), increased rate of distal embolization (odds ratio 2.7, 95% confidence interval, 1.5%-4.9%), longer length of stay (means ratio 1.6, 95% confidence interval, 1.4%-1.8%), and higher in-hospital mortality (odds ratio 2.8, 95% confidence interval, 1.3%-5.9%). ALI was not associated with risk of major amputation or mortality at 1 year. In a multicenter cohort of patients treated with PVI, we found that ALI patients selected for treatment with endovascular techniques experienced greater short-term adverse events but similar long-term outcomes as their critical limb ischemia counterparts. Further studies are needed to refine the selection of ALI patients who are best served by PVI. © 2018 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley.

Loss of genomic stability appears as a key step in colorectal carcinogenesis. Micronucleus (MN) designates a chromosome fragment or an entire chromosme which lags behind mitosis. MN may be noticed as an additional nucleus within the cytoplasm cell during the intermediate mitosis phases. We tested the hypothesis that MN and its related anomalies may be associated with the presence of neoplastic colorectal lesions. Peripheral blood lymphocytes were cultured and microscopically examined. The frequency of micronuclei (FMN) and the presence of nucleoplasmic bridges (NPB) in binucleated cells were compared in patients with of without colorectal neoplastic lesions. We included 45 patients undergoing colonoscopy, 23 males and 22 females, with a median age of 59. 17 patients had polyps, 11 colorectal cancer (CRC) and 17 had a normal colonoscopy. The FMN was significantly higher in women than in men (8.14 vs 4.17, p=0.008); NPB were significantly less frequent in patients with advanced adenomas (>10mm or vilous) or CRC (p=0.044) when compared with patients with normal colonoscopy, hiperplastic polyps or non-advanced adenomas. Micronuclei are more frequent in women, but its frequency was not significantly different in patients with advanced adenomas or CRC. Null or low frequency values for nucleoplasmic bridges presence in peripheral lymphocyte may be predictive for advanced adenomas and colorectal cancer.

The prognostic effects of poor nutritional status and cardiac cachexia on coronary artery disease (CAD) are not clearly understood. A well-accepted nutritional status parameter, the prognostic nutritional index (PNI), which was first demonstrated to be valuable in patients with cancer and those undergoing gastrointestinal surgery, was introduced to patients requiring coronary artery bypass grafting (CABG). The aim of the present study was to evaluate the prognostic value of PNI in patients with CAD undergoing CABG. We evaluated the in-hospital and long-term (3-y) prognostic effect of PNI on 644 patients with CAD undergoing CABG. Baseline characteristics and outcomes were compared among the patients by PNI and categorized accordingly: Q1, Q2, Q3, and Q4. Patients with lower PNI had significantly higher in-hospital and long-term mortality. Patients with lower PNI levels (Q1) had higher in-hospital mortality and had 12 times higher mortality rates than those with higher PNI levels (Q4). The higher PNI group had the lower rates and was used as the reference. Long-term mortality was higher in patients with lower PNI (Q1)-4.9 times higher than in the higher PNI group (Q4). In-hospital and long-term mortality rates were similar in the non-lower PNI groups (Q2-4). The present study demonstrated that PNI, calculated based on serum albumin level and lymphocyte count, is an independent prognostic factor for mortality in patients undergoing CABG.

Short-course preoperative radiotherapy (SC-RT) followed by total mesorectal excision (TME) is one therapeutic option for locally advanced rectal cancer (LARC) patients. Since radio-induced DNA damage may affect tumor immunogenicity, Myeloid-derived suppressor cells (MDSCs) and T regulatory cells (Tregs) were evaluated in 13 patients undergoing SC-RT and TME for LARC. Peripheral Granulocytic-MDSCs (G-MDSC) [LIN−/HLA-DR−/CD11b+/CD14−/CD15+/CD33+], Monocytic (M-MDSC) [CD14+/HLA-DR−/lowCD11b+/CD33+] and Tregs [CD4+/CD25hi+/FOXP3+- CTLA-4/PD1] basal value was significantly higher in LARC patients compared to healthy donors (HD). Peripheral MDSC and Tregs were evaluated at time 0 (T0), after 2 and 5 weeks (T2-T5) from radiotherapy; before surgery (T8) and 6–12 months after surgery (T9, T10). G-MDSC decreased at T5 and further at T8 while M-MDSC cells decreased at T5; Tregs reached the lowest value at T5. LARC poor responder patients displayed a major decrease in M-MDSC after SC-RT and an increase of Treg-PD-1. In this pilot study MDSCs and Tregs decrease during the SC-RT treatment could represent a biomarker of response in LARC patients. Further studies are needed to confirm that the deepest M-MDSC reduction and increase in Treg-PD1 cells within 5–8 weeks from the beginning of treatment could discriminate LARC patients poor responding to SC-RT.

Cardiac surgery is a highly complex procedure which generates worsening of lung function and decreased inspiratory muscle strength. The inspiratory muscle training becomes effective for muscle strengthening and can improve functional capacity. To investigate the effect of inspiratory muscle training on functional capacity submaximal and inspiratory muscle strength in patients undergoing cardiac surgery. This is a clinical randomized controlled trial with patients undergoing cardiac surgery at Instituto Nobre de Cardiologia. Patients were divided into two groups: control group and training. Preoperatively, were assessed the maximum inspiratory pressure and the distance covered in a 6-minute walk test. From the third postoperative day, the control group was managed according to the routine of the unit while the training group underwent daily protocol of respiratory muscle training until the day of discharge. 50 patients, 27 (54%) males were included, with a mean age of 56.7±13.9 years. After the analysis, the training group had significant increase in maximum inspiratory pressure (69.5±14.9 vs. 83.1±19.1 cmH2O, P=0.0073) and 6-minute walk test (422.4±102.8 vs. 502.4±112.8 m, P=0.0031). We conclude that inspiratory muscle training was effective in improving functional capacity submaximal and inspiratory muscle strength in this sample of patients undergoing cardiac surgery.

Glycogen storage diseases are rare genetic disorders of glycogen synthesis, degradation, or metabolism regulation. When these patients are subjected to anesthesia, perioperative complications can develop, including hypoglycemia, rhabdomyolysis, myoglobinuria, acute renal failure, and postoperative fatigue. The objective of this study was to describe the perioperative course of a cohort of patients with glycogen storage diseases. This is a retrospective review of patients with glycogen storage diseases undergoing anesthetic care at our institution from January 1, 1990, through June 30, 2015 to assess perioperative management and outcomes. We identified 30 patients with a glycogen storage disease who underwent 41 procedures under anesthesia management. Intraoperative lactic acidosis developed during 4 major surgeries (3 liver transplants, 1 myectomy), and in all cases resolved within 24 postoperative hours. Lactated Ringer solution was used frequently. Preoperative and intraoperative hypoglycemia was noted in some patients with glycogen storage disease type I, all of which responded to administration of dextrose-containing solutions. No serious postoperative complications occurred. Patients with glycogen storage disease, despite substantial comorbid conditions, tolerates the anesthetic management without major complications. Several patients who experienced self-limited metabolic acidosis were undergoing major surgical procedures, during which acidosis could be anticipated. Close monitoring and management of blood glucose levels of patients with glycogen storage disease type I is prudent.

Patients with breast cancer-the deadliest cancer among women-are at constant risk of developing metastasis. Oxidative stress and hypoxia are common feature of tumor cells that can proliferate even in a resultant metabolic acidosis. Despite the low extracellular pH, intracellular pH of tumor cells remains relatively normal, or even more alkaline due to the action of a membrane protein family known as monocarboxylate transporters (MCTs). The objective of this study was to verify the diagnostic and prognostic value of MCT1 , MCT4 and CD147 in tumor and peripheral blood samples of patients with breast cancer undergoing chemotherapic treatment. Differential expression of MCT1 , MCT4 and CD147 obtained by qPCR was determined by 2 -ΔΔ C q method between biological samples (tumor and serial samples of peripheral) of patients ( n = 125) and healthy women ( n = 25). tumor samples with higher histological grades have shown higher expression of these markers; this higher expression was also observed in blood samples obtained at diagnosis of patients when compared to healthy women and in patients with positive progression of the disease (metastasis development). markers studied here could be a promising strategy in routine laboratory evaluations as breast cancer diagnosis and prognosis.

Cardiac manifestations of Marfan syndrome include aortic root dilation and mitral valve prolapse (MVP). Only scant data exist describing MVP in patients with Marfan syndrome undergoing aortic root replacement. We retrospectively analyzed data from 166 MFS patients with MVP who were enrolled in a prospective multicenter registry of patients who underwent aortic root aneurysm repair. Of these 166 patients, 9% had mitral regurgitation (MR) grade >2, and 10% had MR grade 2. The severity of MVP and MR was evaluated by echocardiography preoperatively and ≤ 3 years postoperatively. Forty-one patients (25%) underwent composite graft aortic valve replacement, and 125 patients (75%) underwent aortic valve-sparing procedures; both groups had similar prevalences of MR grade >2 (P=0.7). Thirty-three patients (20%) underwent concomitant mitral valve (MV) intervention (repair, n=29; replacement, n=4), including all 15 patients with MR grade >2. Only 1 patient required MV reintervention during follow-up (mean clinical follow-up, 31 ± 10 months). Echocardiography performed 21 ± 13 months postoperatively revealed MR >2 in only 3 patients (2%). One early death and 2 late deaths occurred. Although the majority of patients with Marfan syndrome who undergo elective aortic root replacement have MVP, only 20% have concomitant MV procedures. These concomitant procedures do not seem to increase operative risk. In patients with MR grade ≤ 2 who do not undergo a concomitant MV procedure, the short-term incidence of progressive MR is low; however, more follow-up is needed to determine whether patients with MVP and MR grade ≤ 2 would benefit from prophylactic MV intervention.

A meta-analysis of peripheral blood nerve growth factor levels in patients with schizophrenia.

Neurotrophins particularly brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) are crucial modulators in the neurodevelopment and maintenance of central and peripheral nervous systems. Neurotrophin hypothesis of schizophrenia (SCZ) postulated that the changes in the brains of SCZ patients are the result of disturbances of developing processes involving neurotrophic factors. This hypothesis was mainly supported by the abnormal regulation of BDNF in SCZ, especially the decreased peripheral blood BDNF levels in SCZ patients validated by several meta-analyses. However, the regulation of NGF in SCZ remains unclear because of the inconsistent findings from the clinical studies. Therefore, we undertook, to the best of our knowledge, the first systematic review with a meta-analysis to quantitatively summarize the peripheral blood NGF data in SCZ patients compared with healthy control (HC) subjects. A systematic search of Pubmed, PsycINFO and Web of Science identified 13 articles encompassing a sample of 1693 individuals for the meta-analysis. Random-effects meta-analysis showed that patients with SCZ had significantly decreased peripheral blood levels of NGF when compared with the HC subjects (Hedges's g=-0.633, 95% confidence interval (CI)=-0.948 to -0.318, P<0.001). Subgroup analyses revealed reduced NGF levels both in serum (Hedges's g=-0.671, 95% CI=-1.259 to -0.084, P=0.025) and plasma (Hedges's g=-0.621, 95% CI=-0.980 to -0.261, P<0.001) of the patients, and in drug-free (Hedges's g=-0.670, 95% CI=-1.118 to -0.222, P=0.003) and medicated (Hedges's g=-0.357, 95% CI=-0.592 to -0.123, P=0.003) patients with SCZ. Furthermore, meta-regression analyses showed that age, gender and sample size had no moderating effects on the outcome of the meta-analysis, whereas disease severity might be a confounding factor for the meta-analysis. These results demonstrated that patients with SCZ are accompanied by the decreased peripheral blood NGF levels, strengthening

The level of circulating EBV DNA is a prognostic marker in patients with some EBV-associated malignant diseases. To investigate the presence and nature of Epstein-Barr virus (EBV) DNA in the plasma and to evaluate the correlation of plasma concentrations of EBV DNA with the EBV genomic status in peripheral blood T-cells and neoplastic cells and with the clinical outcome of patients with peripheral T-cell and NK-cell lymphomas (PTCL) and peripheral T-cell proliferative diseases (PTPD). EBV DNA in the plasma of 45 patients and 45 controls was measured using real-time PCR. The presence of the EBV genome in the isolated peripheral blood lymphocytes (CD3+ and CD3- cells) was analysed by PCR. Detection of EBV-encoded early RNA (EBER) in corresponding tumor tissues was carried out using in situ hybridization. DNase I digestion was applied to plasma samples to detect naked EBV DNA. Cell-free EBV DNA was detected in 32/38 (84%) of PTCL patients and 5/7 (71%) of PTPD patients, but not in the controls. Patients with EBV genome in peripheral blood CD3+ cells and EBV genome (EBER) in the tumor cells, compared to those without these findings, had significantly higher plasma EBV DNA levels. The majority of circulating EBV DNA molecules was naked form. The plasma EBV DNA levels were not related to survival. The concentration of EBV DNA in the plasma was not a prognostic marker in PTCL and PTPD patients.

[Hereditary heterozygous factor VII deficiency in patients undergoing surgery : Clinical relevance].

A hereditary deficiency in coagulation factor VII (FVII) may affect the international normalized ratio (INR) value. However, FVII deficiency is occasionally associated with a tendency to bleed spontaneously. We hypothesized that perioperative substitution with coagulation factor concentrates might not be indicated in most patients. In this retrospective data analysis, we included all patients with hereditary heterozygous FVII deficiency who underwent surgical procedures at the University Hospital Basel between December 2010 and November 2015. In addition, by searching the literature, we identified publications reporting patients with FVII deficiency undergoing surgical procedures without perioperative substitution. We identified 22 patients undergoing 46 surgical procedures, resulting in a prevalence of 1:1500-2000. Coagulation factor concentrates were administered during the perioperative period in 15 procedures (33 %), whereas in the other 31 procedures (66 %), FVII deficiency was not substituted. No postoperative bleeding or thromboembolic events were reported. In addition, we found no differences in pre- and postoperative hemoglobin and coagulation parameters, with the exception of an improved postoperative INR value in the substituted group. In the literature review, we identified five publications, including 125 patients with FVII deficiency, undergoing 213 surgical procedures with no perioperative substitution. Preoperative substitution using coagulation factor concentrates does not seem to be mandatory in patients with an FVII level ≥15 %. For decision-making on preoperative substitution, patient history of an increased tendency to bleed may be more important than the FVII level or increased INR value.

Chemotherapy-induced peripheral neuropathy (CIPN) is a debilitating side effect that occurs in many patients undergoing chemotherapy. It is often irreversible and frequently leads to early termination of treatment. In this study, we have identified two compounds, lithium and ibudilast, that when administered as a single prophylactic injection prior to paclitaxel treatment, prevent the development of CIPN in mice at the sensory-motor and cellular level. The prevention of neuropathy was not observed in paclitaxel-treated mice that were only prophylactically treated with a vehicle injection. The coadministration of lithium with paclitaxel also allows for administration of higher doses of paclitaxel (survival increases by 60%), protects against paclitaxel-induced cardiac abnormalities, and, notably, does not interfere with the antitumor effects of paclitaxel. Moreover, we have determined a mechanism by which CIPN develops and have discovered that lithium and ibudilast inhibit development of peripheral neuropathy by disrupting the interaction between paclitaxel, neuronal calcium sensor 1 (NCS-1), and the inositol 1,4,5-trisphosphate receptor (InsP3R) to prevent treatment-induced decreases in intracellular calcium signaling. This study shows that lithium and ibudilast are candidate therapeutics for the prevention of paclitaxel-induced neuropathy and could enable patients to tolerate more aggressive treatment regimens.—Mo, M., Erdelyi, I., Szigeti-Buck, K., Benbow, J.

Abstract Numerous studies have been published on comorbid anxiety and depression in patients with vertigo. However, very few studies have separately described and analyzed anxiety or depression in patients with different types of vestibular peripheral vertigo. The present study investigated anxiety and depression among patients with 4 different types of peripheral vertigo. A total of 129 patients with 4 types of peripheral vertigo, namely, benign paroxysmal positional vertigo (BPPV, n = 49), migrainous vertigo (MV, n = 37), Menière disease (MD, n = 28), and vestibular neuritis (VN, n = 15), were included in the present study. Otological and neurootological examinations were carefully performed, and self-rating anxiety scale and self-rating depression scale were used to evaluate anxiety and depression. Patients were divided into 2 groups, according to the vestibular function: normal and abnormal vestibular function. There was no significant difference in the risk of anxiety/depression between these 2 groups. However, for patients with the 4 different vertigo types, the prevalence of anxiety (MV = 45.9%, MD = 50%) and depression (MV = 27%, MD = 28.6%) was significantly higher in the patients with MV or MD than those with BPPV or VN (P < 0.05). Vestibular function is not significantly associated with the risk of anxiety/depression. Anxiety/depression is more common in patients with MV or MD than those with BPPV or VN. This may be due to the different mechanisms involved in these 4 types of vertigo, as well as differences in the prevention and self-control of the patients against the vertigo. PMID:25654382

An association between celiac disease and renal diseases has been suggested, but the results are controversial. To investigate the prevalence of celiac disease autoimmunity among individuals undergoing renal biopsies and to evaluate whether co-existent celiac autoimmunity influences the clinical outcome of the renal disease. The prevalence of celiac autoimmunity (previous diagnosis of celiac disease or positive tissue transglutaminase antibodies) was determined in 827 consecutive patients undergoing kidney biopsies due to clinical indications. Up to 15 years' follow-up data on kidney function and co-morbidities were obtained. Celiac autoimmunity was found in 45 (5.4%) patients. Among the IgA nephropathy patients, 8.2% of had celiac autoimmunity. At the time of kidney biopsy and after a median follow-up of 5 to 6 years, renal function measured by estimated glomerular filtration rate (eGFR) was inferior in IgA nephropathy patients with celiac autoimmunity compared to those without it (P=0.048 and P=0.022, respectively). The prevalence of celiac autoimmunity seems to be high in patients undergoing renal biopsies, especially in patients with IgA nephropathy. Such autoimmunity may be associated with worse renal function in IgA nephropathy. Hence the co-existence of celiac disease should be taken into consideration when treating patients with renal diseases. Copyright © 2017 Editrice Gastroenterologica Italiana S.r.l.

This study examined whether racial/ethnic differences in illness perceptions exist among patients on maintenance hemodialysis. One hundred sixty-one patients with end stage renal disease (ESRD) undergoing maintenance hemodialysis (20% African Americans, 44% Hispanics, 9% Filipinos, and 27% Koreans) completed the Revised Illness Perception Questionnaire. Korean participants had higher emotional disturbance than their counterparts, whereas African-American participants had higher negative perceptions of personal intervention or medical treatment controlling their disease. This study indicates that patients from different racial/ethnic backgrounds undergoing maintenance hemodialysis may perceive their disease differently. This phenomenon could affect clinical outcomes and may require different therapeutic approaches. PMID:22480051

Postoperative hyperglycaemia of diabetic patients undergoing cardiac surgery - a clinical audit.

PubMed

Lehwaldt, Daniela; Kingston, Mary; O'Connor, Sheila

2009-01-01

Previous studies have shown that hyperglycaemia is associated with postoperative complications in cardiac surgical patients. Conversely, well-controlled glucose levels are said to reduce major infectious complications in diabetic patients. The purpose of this clinical audit was to evaluate the blood glucose levels of diabetic patients undergoing cardiac surgery and to determine the effectiveness of postoperative glycaemic control. A group of 150 patients from a large Irish cardiac surgery centre was selected by convenience sampling. An audit tool was designed to capture the patients' blood glucose levels, treatment regimes and postoperative complications. The findings showed major variations between 'high', 'good' and 'borderline' blood glucose levels in the pre- and postoperative phase. Although blood glucose testing practices seemed inconsistent, mean levels measured 'borderline'. Furthermore, the treatment regimes varied greatly and suggest a lack of consensus regarding the management of postoperative hyperglycaemia. A total of 52% (n = 78) patients developed 114 complications with a level of 21.4% (n = 32) postoperative wound infections. The findings from this audit highlight the importance of regular blood glucose testing to enable early detection of hyperglycaemia and timely initiation of appropriate treatments regimes for diabetic patients undergoing cardiac surgery. Findings also show that hyperglycaemia derangement may make a difference in the recovery phase. While patients will benefit from lesser wound infections, hospitals might save costs involved with treating postoperative complications. More consistent blood glucose testing might be achieved through the use of evidence-based protocols. However, the education of staff is as important as it develops knowledge on the complex metabolic interactions of diabetic patients undergoing cardiac surgery. While this means investing in staff education and policy development, costs for daily care and expensive

To characterize trends in pain and functional outcomes and identify risk factors in patients with lumbar spinal stenosis (LSS) and neurogenic claudication undergoing the "Minimally Invasive Lumbar Decompression" (MILD) procedure. Retrospective observational cohort study. Academic multidisciplinary pain center at Stony Brook Medicine. Patients undergoing the MILD procedure from October 2010 to November 2012. De-identified perioperative, pain and function related data for 50 patients undergoing MILD were extracted from the Center for Pain Management's quality assessment database. Data included numerical rating scale (NRS), symptom severity and physical function (Zurich Claudication Questionnaire), functional status (Oswestry Disability Index [ODI]), pain interference scores (National Institutes of Health Patient-Reported Outcomes Measurement Information System [PROMIS]), and patients' self-reported low back and lower extremity pain distribution. No MILD patient incurred procedure-related complications. Average NRS scores decreased postoperatively and 64.3% of patients reported less pain at 3 months. Clinically meaningful functional ODI improvements of at least 20% from baseline were present in 25% of the patients at 6 months. Preliminary analysis of changes in PROMIS scores at 3 months revealed that pre-MILD "severe" lumbar canal stenosis may be associated with high risk of "no improvement." No such impact was observed for NRS or ODI outcomes. Overall, pain is reduced and functional status improved in LSS patients following the MILD procedure at 3 and 6 months. Given the small sample size, it is not yet possible to identify patient subgroups at risk for "no improvement." Continued follow-up of longer-term outcomes appears warranted to develop evidence-based patient selection criteria. Wiley Periodicals, Inc.

The primary objective of this study is to compare the oocyte yield in breast cancer patients undergoing controlled ovarian stimulation (COS) using letrozole and gonadotropins with patients undergoing COS with standard gonadotropins for elective cryopreservation of oocytes. Odds ratios (OR) for the number of mature oocytes were estimated. Pregnancy outcomes for breast cancer patients undergoing frozen-thawed 2-PN embryo transfers (FETs) after oncologic treatment were also noted. 220 and 451 cycles were identified in the breast cancer and the elective cryopreservation groups, respectively. Patients in the former group had lower peak estradiol levels [464.5 (315.5-673.8) pg/mL] compared to the latter [1696 (1058-2393) pg/mL; p < 0.01]. More oocytes were retrieved in the breast cancer group (12.3 ± 3.99) compared to the elective cryopreservation group (10.9 ± 3.86; p < 0.01). The odds for mature oocytes with letrozole and gonadotropins was 2.71 (95% CI 1.29-5.72; p = 0.01). Fifty-six FETs occurred in the breast cancer group. The clinical pregnancy and live birth rates per FET cycle were 39.7%, and 32.3%, respectively. Our findings suggest that COS with letrozole and gonadotropins yield more mature oocytes at lower estradiol levels compared to COS with gonadotropins alone. Breast cancer patients undergoing FET after oncologic treatment have live birth rates comparable to age-matched counterparts.

Peripherally inserted central catheters (PICC) are more and more used for intravenous antibiotic infusions in cystic fibrosis (CF) patients in the Grenoble area (France). The aim of this study was to assess the use of this technique in this indication. 1. Retrospective evaluation of 102 consecutive PICC insertions over 3years and the incidence of adverse events during the therapy. 2. Prospective evaluation of 12 patient's satisfaction and their nurses over a 3-month period. 3. Comparative analysis of single domiciliary treatment costs using PICC versus peripheral catheter (PC). 102 PICC insertions were attempted in 31 patients. Seven failures and 7 complications occurred during the treatment requiring removal of the PICC, i.e. an overall success rate of 86.2% (88/102). Pain during PICC introduction was 4.2/10 (visual analogical scale). Mean satisfaction levels during therapy were 9.3/10 for patients and 8.7/10 for nurses. Compared with PC, all the patients said that PICC was "more comfortable". Differential costs of treatment with PC and with PICC at home were estimated at 57.15€ and 590.16€ respectively. PICC is an alternative to CP for intravenous antibiotherapy in CF patients, providing better safety and comfort. PICC use should be promoted in this indication. Copyright © 2013 SPLF.

Improved sensitivity in patients with peripheral neuropathy: effects of monochromatic infrared photo energy.

PubMed

DeLellis, Salvatore L; Carnegie, Dale H; Burke, Thomas J

2005-01-01

The medical records of 1,047 patients (mean age, 73 years) with established peripheral neuropathy were examined to determine whether treatment with monochromatic infrared photo energy was associated with increased foot sensitivity to the 5.07 Semmes-Weinstein monofilament. The peripheral neuropathy in 790 of these patients (75%) was due to diabetes mellitus. Before treatment with monochromatic infrared photo energy, of the ten tested sites (five on each foot), a mean +/- SD of 7.9 +/- 2.4 sites were insensitive to the 5.07 Semmes-Weinstein monofilament, and 1,033 patients exhibited loss of protective sensation. After treatment, the mean +/- SD number of insensate sites on both feet was 2.3 +/- 2.4, an improvement of 71%. Only 453 of 1,033 patients (43.9%) continued to have loss of protective sensation after treatment. Therefore, monochromatic infrared photo energy treatment seems to be associated with significant clinical improvement in foot sensation in patients, primarily Medicare aged, with peripheral neuropathy. Because insensitivity to the 5.07 Semmes-Weinstein monofilament has been reported to be a major risk factor for diabetic foot wounds, the use of monochromatic infrared photo energy may be associated with a reduced incidence of diabetic foot wounds and amputations.

At present, limited experience exists on the treatment of atrial fibrillation (AF) in patients undergoing mitral valve repair (MVR) for Barlow disease. The aim of this investigation was to prospectively evaluate the radiofrequency ablation of AF in patients undergoing MVR for severe regurgitation due to Barlow disease. From January 1, 2007 to December 31, 2010, out of 85 consecutive patients with Barlow disease, 27 with AF underwent RF ablation associated with MVR. They were examined every 4 months in the first year after surgery and thereafter twice yearly. At follow-up, AF was observed in 4/25 (16.0%). NYHA (New York Heart Association) functional class improved significantly, with no patients in class III or IV (before surgery, 81.5% had been). Otherwise, among 58 patients in sinus rhythm, 6 (11%) developed AF during follow-up. No clinical or echocardiographic predictive factor was found in this subgroup. Results from our investigation suggest that radiofrequency ablation of AF in patients with Barlow disease undergoing MVR for severe regurgitation is effective and should be considered in every patient with Barlow disease and AF undergoing valve surgical repair.

Do-not-resuscitate (DNR) status has been shown to be an independent risk factor for mortality in the post-operative period. Patients with DNR orders often undergo elective surgeries to alleviate symptoms and improve quality of life, but there are limited data on outcomes for informed decision making. Retrospective cohort study. A multi-institutional setting including operating room, postoperative recovery area, inpatient wards, and the intensive care unit. A total of 566 patients with a DNR status and 316,431 patients without a DNR status undergoing elective procedures using the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) from 2012. Patients undergoing elective surgical procedures. We analyzed the risk-adjusted 30-day morbidity and mortality outcomes for the matched DNR and non-DNR cohorts undergoing elective surgeries. DNR patients had significantly increased odds of 30-day mortality (OR 2.51 [1.55-4.05], p < 0.001) compared with non-DNR patients. In the DNR versus non-DNR cohort there was no significant difference in the occurrence of a number of 30-day complications, the rate of resuscitative measures undertaken, including cardiac arrest requiring CPR, reintubation, or return to the OR. The most common complications in both DNR and non-DNR patients undergoing elective procedures were transfusion, urinary tract infection, reoperation, and sepsis. Finally, the DNR patients had a significantly increased total length of hospital stay (7.65 ± 9.55 vs. 6.87 ± 9.21 days, p = 0.002). DNR patients, as compared with non-DNR patients, have increased post-operative mortality but not morbidity, which may arise from unmeasured severity of illness or transition to comfort care in accordance with a patient's wishes. The informed consent process for elective surgeries in this patient population should include a discussion of acceptable operative risk. Copyright © 2018 Elsevier Inc. All rights reserved.

The present study was designed to analyze the serum levels of aspartate and alanine aminotransferases, gamma-glutamyl transferase, and the hematocrit in patients with chronic kidney disease who were undergoing peritoneal dialysis or hemodialysis. Twenty patients on peritoneal dialysis and 40 on hemodialysis were assessed, and the patients were matched according to the length of time that they had been on dialysis. Blood samples were collected (both before and after the session for those on hemodialysis) to measure the enzymes and the hematocrit. In the samples from the patients who were undergoing peritoneal dialysis, the aspartate and alanine aminotransferase levels were slightly higher compared with the samples collected from the patients before the hemodialysis session and slightly lower compared with the samples collected after the hemodialysis session. The levels of gamma-glutamyl transferase in the hemodialysis patients were slightly higher than the levels in the patients who were undergoing peritoneal dialysis. In addition, the levels of aminotransferases and gamma-glutamyl transferase that were collected before the hemodialysis session were significantly lower than the values collected after the session. The hematocrit levels were significantly lower in the patients who were on peritoneal dialysis compared with the patients on hemodialysis (both before and after the hemodialysis session), and the levels were also significantly lower before hemodialysis compared with after hemodialysis. The aminotransferase levels in the patients who were undergoing peritoneal dialysis were slightly higher compared with the samples collected before the hemodialysis session, whereas the aminotransferase levels were slightly lower compared with the samples collected after the session. The hematocrits and the aminotransferase and gamma-glutamyl transferase levels of the samples collected after the hemodialysis session were significantly higher than the samples collected before

Biliary lithiasis is not much frequent in paediatric patients. The manegement of cholelithiasis in patients undergoing laparoscopic cholecystectomy is still controversial. We propose the preoperatory echographic study of the biliary tree 24-48 h before surgery, as the first choice, instead of the intraoperatory cholangiography. We made a retrospective study of 42 patients undergoing laparoscopic cholecystectomy due to symptomatic biliary lithiasis during the last 15 years, with ages between 18 months and 17-years-old (mean age 9,6-years-old) and weight between 11 and 70 kg (mean weight 42 kg) at the moment of surgery. Six of them had haematological illnesses, 17 came to the hospital because of acute abdominal pain, 10 had been studied because of recurrent abdominal pain and 9 had casual diagnoses. Abdominal sonography was performed in all patients 24-48 hours before surgery. Four children were diagnosed of biliary duct lithiasis: two choledocolithiasis and two stones in the cystic duct. One of the cystic stones was extracted in the operating room and the rest resolved spontaneously. One patient presented dilatation of choledocal duct after surgery, without any stones' evidence. Also this patient resolved spontaneously. We had no complications. Biliary lithiasis is not frequent in children, even if it seems to be increasing. A few of these patients will suffer of choledocolithiasis. The intraoperatory exploration of the biliary tree during laparoscopic surgery is technically difficult due the small size of paediatric patients. Cholangiography is not always successful and can produce some important complications as pancreatitis. Preoperative sonography 24-48 hours before surgery is a safe and efficient method for the diagnosis and follow-up of paediatric patients with biliary lithiasis undergoing laparoscopic cholecystectomy. It is safe enough to be performed without intraoperatory cholangiography.

Objective: Percutaneous coronary intervention has been effective in increasing longevity of patients with cardiovascular disease. However, the evidence shows that the quality of life after the intervention is still lower than optimal level. The quality of life can be affected by various factors. The aim of this study is to determine the quality of life and its related factors in patients undergoing coronary angioplasty. Methods: This cross-sectional study was performed on 106 patients undergoing coronary angioplasty during 2015-2016. This study population included all patients who referred to a cardiac clinic in Rasht, Iran, were passed 3 months after their angioplasty. Research samples met the inclusion criteria and were willing to participate to the study, were selected gradually (continually). Research tools were a self-structured questionnaire regarding factors associated with the quality of life and the MacNew quality of life questionnaire. Data were collected through asking patients questions and using patient’s medical records. Data analysis was conducted using descriptive and inferential statistics. Results: The results of multivariate linear regression analysis showed that independent variables of age (P = 0.0001), the number of diseased vessels (P = 0.0001), and the number of comorbidities (P < 0.05) were the most important factors associated with the quality of life. Conclusion: Health-care professionals can play an effective role in promoting the quality of life of patients undergoing coronary angioplasty by modifying lifestyle based on the related factors and to provide comprehensive care programs, especially for elderly.

The impact of permanent pacemaker (PPM) on long-term clinical outcomes of patients undergoing percutaneous coronary intervention (PCI) has not been studied. PPM may increase heart failure (HF) burden on patients undergoing PCI. We recruited consecutive patients undergoing PCI and carried out a nested case-control study. Patients with confirmed PPM undergoing first PCI were identified and matched by age and sex in 1:1 fashion to patients without PPM undergoing first PCI. Clinical data were collected and analyzed. The primary endpoint outcomes were all-cause mortality and hospitalization for HF. The final analysis included 156 patients. The mean follow-up period was 4.6 ± 2.9 years. The overall all-cause mortality was 21.15%, without significant difference between the 2 groups (21.79% vs 20.51%; P = 0.85). However, the rate of HF-related hospitalization was significantly higher in patients with PPM than in controls (26.92% vs 10.26%; P = 0.008). After adjustment for hypertension, type 2 diabetes mellitus, hyperlipidemia, chronic kidney disease, stroke, left ventricular ejection fraction, brain natriuretic peptide, and acute coronary syndrome (ACS), PCI patients with PPM were still associated with a greater hospitalization rate for HF (odds ratio: 4.31, 95% confidence interval: 0.94-19.80, P = 0.061). Further analysis in the ACS subgroup showed VVI-mode pacing enhanced the risk for HF-associated hospitalization (adjusted odds ratio: 8.27, 95% confidence interval: 1.37-49.75, P = 0.02). PPM has no effect on all-cause mortality in patients undergoing first PCI but significantly increases the HF-associated hospitalization rate, especially in ACS patients. © 2016 Wiley Periodicals, Inc.

Continuous positive airway pressure (CPAP) has been used as an effective support to decrease the negative pulmonary effects of coronary artery bypass graft (CABG) surgery. However, it is unknown whether CPAP can positively influence patients undergoing CABG during exercise. This study evaluated the effectiveness of CPAP on the first day of ambulation after CABG in patients undergoing inpatient cardiac rehabilitation (CR). Fifty-four patients after CABG surgery were randomly assigned to receive either inpatient CR and CPAP (CPG) or standard CR without CPAP (CG). Cardiac rehabilitation included walking and CPAP pressures were set between 10 to 12 cmH2O. Participants were assessed on the first day of walking at rest and during walking. Outcome measures included breathing pattern variables, exercise time in seconds (ETs), dyspnea/leg effort ratings, and peripheral oxygen saturation (SpO2). Twenty-seven patients (13 CPG vs 14 CG) completed the study. Compared with walking without noninvasive ventilation assistance, CPAP increased ETs by 43.4 seconds (P = .040) during walking, promoted better thoracoabdominal coordination, increased ventilation during walking by 12.5 L/min (P = .001), increased SpO2 values at the end of walking by 2.6% (P = .016), and reduced dyspnea ratings by 1 point (P = .008). Continuous positive airway pressure can positively influence exercise tolerance, ventilatory function, and breathing pattern in response to a single bout of exercise after CABG.

The aim of this study was to investigate the relationships between personality and joint-specific function, general physical and general mental health in patients undergoing total hip (THA) and knee arthroplasty (TKA). One hundred and eighty-four patients undergoing THA and 205 undergoing TKA were assessed using the Eysneck Personality Questionnaire, brief version (EPQ-BV). General physical and mental health was measured using the Short-Form 12 (SF-12) questionnaire and the EuroQol (EQ-5D). Joint-specific function was measured using the Oxford hip or knee score. The "unstable introvert" personality type was associated with poorer pre-operative function and health in patients with hip arthrosis. In patients with knee arthrosis, there was poorer general health in those with "stable extrovert" and "unstable introvert" types. Personality was not an independent predictor of outcome following TKA or THA. The main predictor was pre-operative function and health. Comorbidity was an important covariate of both pre-operative and postoperative function. Personality may play a role in the interaction of these disease processes with function and health perception. It may also affect the response and interpretation of psychometric and patient-reported outcome measures. It may be important to characterise and identify these traits in potential arthroplasty patients as it may help deliver targeted education and management to improve outcomes in certain groups.

We identified all gynecologic oncology patients undergoing an SBFT from January 2004 to December 2009. We characterized the SBFT as normal, delayed transit, partial obstruction, or complete obstruction. Patient outcomes were correlated with the SBFT results. Seventy patients underwent 79 SBFT examinations with Gastrografin to evaluate their bowel dysfunction. The overall rate of operative intervention was 23%. A total of 69% of patients with a complete obstruction underwent surgery as compared to 21% of patients with a partial obstruction (p = 0.002). Return of bowel function was significantly longer in patients with complete obstructions as compared to patients with partial obstructions (48 vs. 8 hours, p = 0.006). Length of stay was longest in patients with complete obstructions. The majority of patients with a complete obstruction on SBFT will require surgical intervention and have a protracted hospital stay. Patients with delayed transit or a partial obstruction on SBFT usually will have resolution of their bowel dysfunction with conservative management.

Patients undergoing primary hepatic resection often develop hemostatic dysfunction associated with cirrhosis. We retrospectively surveyed pre- and postoperative prothrombin time (PT) and the PT expressed as international normalized ratio (PT-INR) in 39 patients undergoing primary liver resection. We also compared PT changes between primary and metastatic cancer cases (8 cases). Postoperative PT-INR was 1.40 ± 0.38, which was significantly prolonged compared to preoperative PT-INR of 1.08 ± 0.07. Preoperative PT was over 70% in all 39 patients undergoing primary liver resection, whereas postoperative PT was less than 60% in 13 of 39 patients. No significant difference was found in preoperative PT-INR between primary and metastatic cancer cases, but postoperative PT-INR was significantly prolonged in primary cancer cases. Patients undergoing primary liver resection are susceptible to hemostatic dysfunction, even with preoperative PT levels within normal limits.

Generally, before being operated on, patients will be given informal information by the healthcare providers involved in the care of the patients (doctors, nurses, ward clerks, or healthcare assistants). This information can also be provided formally in different formats including written information, formal lectures, or audio-visual recorded information. To compare the benefits and harms of formal preoperative patient education for patients undergoing laparoscopic cholecystectomy. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2, 2013), MEDLINE, EMBASE, and Science Citation Index Expanded to March 2013. We included only randomised clinical trials irrespective of language and publication status. Two review authors independently extracted the data. We planned to calculate the risk ratio with 95% confidence intervals (CI) for dichotomous outcomes, and mean difference (MD) or standardised mean difference (SMD) with 95% CI for continuous outcomes based on intention-to-treat analyses when data were available. A total of 431 participants undergoing elective laparoscopic cholecystectomy were randomised to formal patient education (215 participants) versus standard care (216 participants) in four trials. The patient education included verbal education, multimedia DVD programme, computer-based multimedia programme, and Power Point presentation in the four trials. All the trials were of high risk of bias. One trial including 212 patients reported mortality. There was no mortality in either group in this trial. None of the trials reported surgery-related morbidity, quality of life, proportion of patients discharged as day-procedure laparoscopic cholecystectomy, the length of hospital stay, return to work, or the number of unplanned visits to the doctor. There were insufficient details to calculate the mean difference and 95% CI for the difference in pain scores at 9 to 24 hours (1 trial; 93 patients); and we did not identify clear evidence of

Should patients with Björk-Shiley valves undergo prophylactic replacement?

About 85,000 patients have undergone replacement of diseased heart valves with prosthetic Björk-Shiley convexo-concave (CC) valves. These valves are prone to fracture of the outlet strut, which leads to acute valve failure that is usually fatal. Should patients with these valves undergo prophylactic replacement to avoid fracture? The incidence of strut fracture varies between 0% and 1.5% per year, depending on valve opening angle (60 degrees or 70 degrees), diameter (less than 29 mm or greater than or equal to 29 mm), and location (aortic or mitral). Other factors include the patient's life expectancy and the expected morbidity and mortality associated with reoperation. We have used decision analysis to identify the patients most likely to benefit from prophylactic reoperation. The incidence of outlet strut fracture was estimated from the data of three large studies on CC valves, and stratified by opening angle, diameter, and location. A Markov decision analysis model was used to estimate life expectancy for patients undergoing prophylactic valve replacement and for those not undergoing reoperation. Prophylactic valve replacement does not benefit patients with CC valves that have low strut fracture risks (60 degrees aortic valves and less than 29 mm, 60 degrees mitral valves). For most patients with CC valves that have high strut fracture risks (greater than or equal to 29 mm, 70 degrees CC), prophylactic valve replacement increases life expectancy. However, elderly patients with such valves benefit from prophylactic reoperation only if the risk of operative mortality is low. Patient age and operative risk are most important in recommendations for patients with CC valves that have intermediate strut fracture risks (less than 29 mm, 70 degrees valves and greater than or equal to 29 mm, 60 degrees mitral valves). For all patients and their doctors facing the difficult decision on whether to replace CC valves, individual estimates of operative mortality risk that

This study is the first to use 10- to 90-kg tissue-equivalent phantoms as patient surrogates to measure peripheral skin doses (Dskin) in lung cancer treatment through Volumetric Modulated Arc Therapy of the Axesse linac. Five tissue-equivalent and Rando phantoms were used to simulate lung cancer patients using the thermoluminescent dosimetry (TLD-100H) approach. TLD-100H was calibrated using 6 MV photons coming from the Axesse linac. Then it was inserted into phantom positions that closely corresponded with the position of the represented organs and tissues. TLDs were measured using the Harshaw 3500 TLD reader. The ICRP 60 evaluated the mean Dskin to the lung cancer for 1 fraction (7 Gy) undergoing VMAT. The Dskin of these phantoms ranged from 0.51±0.08 (10-kg) to 0.22±0.03 (90-kg) mSv/Gy. Each experiment examined the relationship between the Dskin and the distance from the treatment field. These revealed strong variations in positions close to the tumor center. The correlation between Dskin and body weight was Dskin (mSv) = -0.0034x + 0.5296, where x was phantom's weight in kg. R2 is equal to 0.9788. This equation can be used to derive an equation for lung cancer in males. Finally, the results are compared to other published research. These findings are pertinent to patients, physicians, radiologists, and the public.

The purpose of this study was to assess the extent to which patients undergoing flexible bronchoscopy (FOB) experience pain and to identify patient factors and process of care factors that are associated with pain. We conducted a prospective cohort study on 481 patients undergoing FOB. Overall control of pain during FOB was the primary outcome. The mean age of the patients was 48 yr, 50% were male, and 32% required supplemental oxygen prior to FOB. Pain control was excellent in 36% of patients, but 10% considered it to be fair or poor. Patient factors associated with excellent pain control were excellent health (versus poor health, OR = 6.25 [95% CI, 2.28-16.67]), more education (college education versus high school education, OR = 1.72 [95% CI, 1.05-2.86]), and not having asthma (OR = 2.86 [95% CI, 1.09-7.14]). Process of care factors associated with excellent pain control were not being bothered by scope insertion (versus bothered, OR = 3.65 [95% CI, 1.99-6.98]), no memory of FOB (versus some memory, OR = 2.33 [95% CI, 1.24-4.44]), and higher ratings of information about the procedure (per 1-point increase on a 12-point scale, OR = 1.57 [95% CI, 1.41-1.78]). This is the first large-scale, prospective study to evaluate patient and process of care factors that influence pain control during FOB. It demonstrated that there are patient characteristics and process of care factors that need to be considered when evaluating pain during bronchoscopy. Improved preparation of patients with lower education, inferior health status, and asthma may lead to decreased pain during FOB. Bronchoscopists may be able to reduce pain during FOB by identifying methods to decrease pain on scope insertion, by improving the information provided to patients, and by achieving greater levels of amnesia during FOB.

To evaluate the effects of an intensive postoperative physiotherapy program focused on respiratory exercises in patients undergoing lobectomy by open thoracotomy. Quasi-experimental study. Tertiary referral academic hospital. 208 patients undergoing lobectomy by open thoracotomy. Control group patients (n=102) received standard medical/nursing care, and experimental group patients (n=106) added to the standard clinical pathway a daily physiotherapy program focused on respiratory exercises until discharge. Analyzed outcomes were the frequency of postoperative pulmonary complications (PPCs) more amenable to physiotherapy (pneumonia, atelectasis and respiratory insufficiency) and length of hospital stay (LOS). Both groups were comparable regarding preoperative and surgical characteristics. Incidence of PPCs was 20.6% in control and 6.6% in experimental group (P=.003). Median (IQR) LOS in control group was 14 (7) days (Huber M estimator 14.21) and 12 (6) days (Huber M estimator 12.81) in experimental. Logistic regression model identified the evaluated physiotherapy program (P=.017; EXP [B] 95% CI 0.081-0.780) and % FEV1 (P=.042; EXP [B] 95% CI 0.941-0.999) as protective factors for the development of PPCs in patients undergoing lobectomy. Implementing a postoperative intensive physiotherapy program focused on respiratory exercises reduces the risk of PPCs and resultant LOS on patients undergoing lobectomy. Copyright © 2016 SEPAR.

2009-10-01

A 52-year-old patient, ASA physical status IV, undergoing a radical prostatectomy for cancer with a robotic system had a cardiac arrest 3 hours into the case. All attempts to resuscitate were unsuccessful, and several hours later he was pronounced dead. Underlying patient comorbidity and procedural issues contributed to the patient's death. The patient had a history of coronary artery disease that required the placement of drug-eluting stents 2 years before this surgical procedure. The preoperative cardiac evaluation and pharmacological management of patients with drug-eluting coronary stents are reviewed. There are a number of positional and technical considerations for patients undergoing robotic surgical procedures, especially in relation to the requirement of low-lithotomy and steep Trendelenburg positions. The cardiac and respiratory systems are especially vulnerable to the extreme and lengthy head-down position. The needed positioning, combined with the problems associated with insufflation, presents a unique challenge in anesthetic management. This course reviews the current literature on the surgical implications for patients with drug-eluting stents and the physiologic factors related to position and pneumoperitoneum and their associated stressors. By using a review of the contemporary literature, a best-evidence approach to anesthetic management is reviewed.

Gestational diabetes Mellitus has been considered an inflammatory disease involving different cells and mediators in its development. The role of innate immune cells in GDM physiopathology remains unclear, therefore this study was conducted to assess monocyte profile in GDM patients. This was a case-control study including 20 glucose-tolerant pregnant women (controls) and 18 GDM patients. Flow cytometry was used to assess peripheral blood monocytes subsets (classical, intermediate, non-classical), the expression of TLR4 and CCR2 chemokine receptor (CD192) and cytokines (TNFA, IL6, IL10) secretion by monocytes subsets. In addition, sCD14 serum levels were evaluated by ELISA. We observed increased percentage of CD14 + cells, decreased frequency of intermediate monocytes (CD14 + CD16 + ), and lower percentage of circulating monocytes (classical, intermediate and non-classical) that express TLR4 in the diabetic group compared to controls. Soluble CD14 + serum levels were higher in GDM patients compared to controls. There were no differences in the expression of the CCR2 chemokine receptor and cytokines (TNFA, IL6 and IL10) secretion between the studied groups. Our results demonstrated that GDM patients present impaired monocyte profile in the peripheral blood, suggesting that these cells are involved in GDM physiopathology. Copyright © 2017 Elsevier Ltd.

Whether the unaffected function of the hand of patients presenting with nerve injury is affected remains inconclusive. We aimed to evaluate whether there are differences in finger tapping following central or peripheral nerve injury compared with the unaffected hand and the ipsilateral hand of a healthy subject. Thirty right brain stroke patients with hemiplegia, 30 left arm peripheral nerve injury cases, and 60 healthy people were selected. We tested finger tapping of the right hands, and each subject performed the test twice. Finger tapping following peripheral nerve injury as compared with the unaffected hand and the dominant hand of a healthy person was markedly higher than was found for central nerve injury (P < 0.05). Finger tapping of the male peripheral group's unaffected hand and the control group's dominant hand was significantly higher than the central group (P < 0.001). However, finger tapping of the female control group's dominant hand was significantly higher than the central group's unaffected hand (P < 0.01, P = 0.002), the peripheral group's unaffected hand (P < 0.05, P = 0.034). The unaffected function of the hand of patients with central and peripheral nerve injury was different as compared with the ipsilateral hand of healthy individuals. The rehabilitation therapist should intensify the practice of normal upper limb fine activities and coordination of the patient.

Background Breast reconstruction is associated with multiple risk factors for venous thromboembolism. However, the incidence of deep vein thrombosis in patients undergoing breast reconstruction is uncertain. Objective The aim of this study was to prospectively evaluate the incidence of deep vein thrombosis in patients undergoing breast reconstruction using autologous tissue transfer and to identify potential risk factors for deep vein thrombosis. Methods Thirty-five patients undergoing breast reconstruction were enrolled. We measured patients' preoperative characteristics including age, body mass index (kg/m 2 ), and risk factors for deep vein thrombosis. The preoperative diameter of each venous segment in the deep veins was measured using duplex ultrasound. All patients received intermittent pneumatic pump and elastic compression stockings for postoperative thromboprophylaxis. Results Among the 35 patients evaluated, 11 (31.4%) were found to have deep vein thrombosis postoperatively, and one patient was found to have pulmonary embolism postoperatively. All instances of deep vein thrombosis developed in the calf and were asymptomatic. Ten of 11 patients underwent free flap transfer, and the remaining one patient received a latissimus dorsi pedicled flap. Deep vein thrombosis incidence did not significantly differ between patients with a free flap or pedicled flap (P = 0.13). Documented risk factors for deep vein thrombosis demonstrated no significant differences between patients with and without deep vein thrombosis. The diameter of the common femoral vein was significantly larger in patients who developed postoperative deep vein thrombosis than in those who did not ( P < 0.05). Conclusions The morbidity of deep vein thrombosis in patients who underwent breast reconstruction using autologous tissue transfer was relatively high. Since only the diameter of the common femoral vein was predictive of developing postoperative deep vein thrombosis, postoperative

Disease-specific categories of the International Classification of Functioning, Disability and Health have not yet been described for patients with chronic peripheral arterial obstructive disease (PAD). The authors examined the relationship between the categories of the Brief Core Sets for ischemic heart diseases with the Peripheral Artery Questionnaire and the ankle-brachial index to determine which International Classification of Functioning, Disability and Health categories are most relevant for patients with PAD. This is a retrospective cohort study including 77 patients with verified PAD. Statistical analyses of the relationship between International Classification of Functioning, Disability and Health categories as independent variables and the endpoints Peripheral Artery Questionnaire or ankle-brachial index were carried out by simple and stepwise linear regression models adjusting for age, sex, and leg (left vs. right). The stepwise linear regression model with the ankle-brachial index as dependent variable revealed a significant effect of the variables blood vessel functions and muscle endurance functions. Calculating a stepwise linear regression model with the Peripheral Artery Questionnaire as dependent variable, a significant effect of age, emotional functions, energy and drive functions, carrying out daily routine, as well as walking could be observed. This study identifies International Classification of Functioning, Disability and Health categories in the Brief Core Sets for ischemic heart diseases that show a significant effect on the ankle-brachial index and the Peripheral Artery Questionnaire score in patients with PAD. These categories provide fundamental information on functioning of patients with PAD and patient-centered outcomes for rehabilitation interventions.

Residual platelet function despite treatment with clopidogrel may predict an unfavourable cardiovascular outcome. The majority of studies have investigated the effects of clopidogrel administration in conjunction with aspirin in patients undergoing percutaneous coronary intervention. The primary objective of the present study was to assess the platelet response to clopidogrel in the absence of aspirin in patients with peripheral arterial occlusive disease (PAOD) and to investigate whether non-responsiveness to clopidogrel is reproducible during long-term follow-up. Fifty-four clinically stable PAOD patients on a maintenance dose of 75 mg/d clopidogrel were enrolled in this study. Platelet function was assessed at baseline and after a median follow-up of 18 months using light transmittance aggregometry (LTA) with 2 microM ADP as an agonist. HPLC-coupled mass spectrometry was used to detect clopidogrel and clopidogrel carboxylic acid, the main metabolite of clopidogrel. Residual platelet function, as defined by late aggregation values within the reference range (i.e., >43%), was observed in 35.2% of patients at baseline and 17.6% during follow-up. During the observation period, 26.5% had switched from responder to non-responder status or vice versa. Among non-responders, either clopidogrel or its metabolite was detected in 89.5% and 83.3% of patients at baseline and at follow-up, respectively. We conclude that non-responsiveness to clopidogrel as determined by ADP-induced LTA is not stable over time. This phenomenon cannot be attributed to non-compliance alone.

To demonstrate the importance of pre-operative ear, nose and throat assessment in patients undergoing endoscopic, transsphenoidal surgery for pituitary tumours. Literature pertaining to the pre-operative otorhinolaryngological assessment and management of patients undergoing endoscopic anterior skull base surgery is sparse. We describe two cases from our series of 59 patients undergoing endoscopic pituitary surgery. The first case involved a young male patient with a large pituitary macroadenoma. His main complaint was visual impairment. He had no previous history of sinonasal pathology and did not complain of any nasal symptoms during the pre-operative neurosurgical assessment. At the time of surgery, a purulent nasal discharge was seen emanating from both middle meati. Surgery was abandoned due to the risk of post-operative meningitis, and postponed until the patient's chronic rhinosinusitis was optimally managed. The second patient was a 47-year-old woman with a large pituitary macroadenoma, who presented to the neurosurgical department with a main complaint of diplopia. She too gave no history of previous nasal problems, and she underwent uneventful surgery using the endoscopic, transnasal approach. Two weeks after surgery, she presented to the emergency unit with severe epistaxis. A previous diagnosis of hereditary haemorrhagic telangiectasia was discovered, and further surgical and medical intervention was required before the epistaxis was finally controlled. Pre-operative otorhinolaryngological assessment is essential prior to endoscopic pituitary or anterior skull base surgery. A thorough otorhinolaryngological history will determine whether any co-morbid diseases exist which could affect the surgical field. Nasal anatomy can be assessed via nasal endoscopy and sinusitis excluded. Computed tomography imaging is a valuable aid to decisions regarding additional procedures needed to optimise access to the pituitary fossa.

Marriage confers various health advantages in the general population. However, the added value of marriage among patients who undergo percutaneous coronary intervention (PCI) beyond the standard cardiovascular risk factors is not clear. This study aimed to assess the effects of marital status on outcomes of patients undergoing elective or urgent PCI. Clinical observational analysis of consecutive patients undergoing elective or urgent PCI from 1993 to 2011 was performed. Patients were stratified by marital status, comparing married to unmarried patients. Clinical outcome up to 12 months was obtained by telephone contact or office visit. A total of 11,216 patients were included in the present analysis; 55% were married and 45% unmarried. Significant differences in baseline characteristics were noted, including a lower prevalence of hypertension (86% vs 88%), diabetes (34% vs 38%), and smoking (19% vs 25%) among married vs unmarried patients, respectively (P < .001). However, married patients had a higher prevalence of hypercholesterolemia and family history of coronary artery disease. Early and late major adverse cardiac event rates were significantly lower for married vs unmarried patients up to 1 year (13.3% vs 8.2%, P < .001). Married status was independently associated with improved outcome in multivariable analysis (hazard ratio 0.7, 95% CI 0.6-0.9). Married patients who undergo urgent or elective PCI have superior short- and long-term outcomes up to 1 year when compared with unmarried patients. These benefits persist after adjustment for multiple traditional cardiovascular risk factors. © 2013.

Background and objectives Despitethe multiple depicted associations of CKD with reduced cardiovascular and overall prognoses, the association of CKD with outcome of patients undergoing transcatheter aortic valve implantation has still not been well described. Design, setting, participants, & measurements Data from all hospitalized patients who underwent transcatheter aortic valve implantation procedures between January 1, 2010 and December 31, 2013 in Germany were evaluated regarding influence of CKD, even in the earlier stages, on morbidity, in-hospital outcomes, and costs. Results A total of 28,716 patients were treated with transcatheter aortic valve implantation. A total of 11,189 (39.0%) suffered from CKD. Patients with CKD were predominantly women; had higher rates of comorbidities, such as coronary artery disease, heart failure at New York Heart Association 3/4, peripheral artery disease, and diabetes; and had a 1.3-fold higher estimated logistic European System for Cardiac Operative Risk Evaluation value. In-hospital mortality was independently associated with CKD stage ≥3 (up to odds ratio, 1.71; 95% confidence interval, 1.35 to 2.17; P<0.05), bleeding was independently associated with CKD stage ≥4 (up to odds ratio, 1.82; 95% confidence interval, 1.47 to 2.24; P<0.001), and AKI was independently associated with CKD stages 3 (odds ratio, 1.83; 95% confidence interval, 1.62 to 2.06) and 4 (odds ratio, 2.33; 95% confidence interval, 1.92 to 2.83 both P<0.001). The stroke risk, in contrast, was lower for patients with CKD stages 4 (odds ratio, 0.23; 95% confidence interval, 0.16 to 0.33) and 5 (odds ratio, 0.24; 95% confidence interval, 0.15 to 0.39; both P<0.001). Lengths of hospital stay were, on average, 1.2-fold longer, whereas reimbursements were, on average, only 1.03-fold higher in patients who suffered from CKD.

To report the initial use of a novel thrombectomy device for revascularization of below-the-knee thromboembolic occlusions encountered during proximal revascularization procedures. The ReVive PV Peripheral Thrombectomy Device is a non-detachable, self-expanding stent-like device recently approved for peripheral thrombectomy. Four patients (3 women; mean age 68.8 years) undergoing proximal revascularization procedures experienced embolic occlusions of all 3 trifurcation vessels in 1 patient, the tibioperoneal trunk alone in 2 cases, and the peroneal artery alone in the last patient. In all cases, the involved arteries represented the primary or sole vessel(s) providing outflow to the lower extremity. In each case, the ReVive PV device was used to successfully extract the thrombus and restore flow to the distal extremity. No complications were encountered during any of the procedures. The ReVive PV peripheral thrombectomy device may facilitate the safe and efficient revascularization of distal arterial embolic occlusions.

While transradial approach to conduct percutaneous coronary interventions offers multiple advantages, the procedure can cause radial artery damage and occlusion. Because radial artery is the preferred site for the creation of an arteriovenous fistula to provide dialysis, patients with chronic kidney disease are particularly dependent on radial artery for their long-term survival. In this retrospective study, we investigated the prevalence of chronic kidney disease in patients undergoing coronary interventions via radial artery. Stage of chronic kidney disease was based on estimated glomerular filtration rate and National Kidney Foundation - Kidney Disease Outcomes Quality Initiative guidelines. A total of 497 patients undergoing transradial percutaneous coronary interventions were included. Over 70.4% (350/497) of the patients had chronic kidney disease. Stage II chronic kidney disease was observed in 243 (69%) patients (estimated glomerular filtration rate = 76.0 ± 8.4 mL/min). Stage III was observed in 93 (27%) patients (estimated glomerular filtration rate = 49 ± 7.5 mL/min). Stage IV chronic kidney disease was observed in 5 (1%) patients (estimated glomerular filtration rate = 25.6 ± 4.3 mL/min) and Stage V chronic kidney disease was observed in 9 (3%) patients (estimated glomerular filtration rate = 9.3 ± 3.5 mL/min). Overall, 107 of 350 patients (30%) had advanced chronic kidney disease, that is, stage III-V chronic kidney disease. Importantly, 14 of the 107 (13%) patients had either stage IV or V chronic kidney disease. This study finds that nearly one-third of the patients undergoing transradial percutaneous coronary interventions have advanced chronic kidney disease. Because many of these patients may require dialysis, the use of radial artery to conduct percutaneous coronary interventions must be carefully considered in chronic kidney disease population.

Vitamin D deficiency was reported to be associated with diabetic peripheral neuropathy. But the association in Chinese population and the screening value of vitamin D deficiency for diabetic peripheral neuropathy were unknown. A total of 861 patients with type 2 diabetes were recruited in this cross-sectional study. Vitamin D deficiency was defined as serum circulating 25-hydroxyvitamin D(25(OH)D) level < 20 ng/mL. Peripheral neuropathy was evaluated by neurological symptoms, neurological signs, neurothesiometer and electromyogram. The patients with diabetic peripheral neuropathy had significantly lower serum 25(OH)D concentration (15.59 ± 7.68 ng/mL) and higher prevalence of vitamin D deficiency (80%) than patients with signs of diabetic peripheral neuropathy (17.66 ± 7.50 ng/mL; 64.5%) and non-DPN patients (18.35 ± 6.60; 61.7%) (all p < 0.01). Spearman's correlation analysis showed that serum circulating 25(OH)D level was closely associated with DPN (r = 0.121) and signs of DPN (r = 0.111) (both p < 0.01). After adjusting for all potential confounders, VDD was still linked with increased risk of DPN [odds ratio 2.59 (1.48-4.53)] (p < 0.01). Logistical regression analysis further revealed that VDD was an independent risk factor for DPN (β = 0.88) (p < 0.01). Receiver operating characteristic analysis indicated that serum 25(OH)D < 17.22 ng/mL hinted the signs of DPN and serum 25(OH)D < 16.01 ng/mL predicted the occurrence of DPN (both p < 0.01). Vitamin D deficiency is an independent risk factor for diabetic peripheral neuropathy and may be a potential biomarker for peripheral neuropathy in Chinese patients with type 2 diabetes.

Purpose: Peripheral neuropathy (PN) is known as a major contributor of the worsening of ischemic symptoms and the foot ulceration in patients with peripheral arterial occlusive disease (PAOD). However, there are few studies reporting the prevalence and risk factors for PN in PAOD. This study aimed to evaluate these issues for PN and to establish the importance of screening as additional treatment target for PN in PAOD. Materials and Methods: A total of 52 limbs with PAOD were enrolled from January 2011 to December 2012. PN was divided into radiculopathy, ischemic PN (IPN), and diabetic PN (DPN), based on electromyographic findings. We investigated the prevalence of overall PN and subtypes of PN and then analyzed the risk factors. Results: The prevalence of overall PN in PAOD was 43 of 52 limbs (82.7%). In terms of subtypes of PN, the prevalence rate of radiculopathy and IPN was 30.8% and 23.1%, respectively. DPN showed in 22 limbs (73.3%) among 30 diabetic limbs. There was no significant correlation between each type of PN and ischemic symptoms. Our analysis showed that coronary artery disease (CAD) was a significant risk factor (P=0.01) for IPN, however, did not identify any significant risk factors for DPN. Conclusion: This present study indicated that most patients with PAOD had PN and CAD was a risk factor for IPN. In particular, PAOD with diabetes represented a higher prevalence for DPN. Our study suggests that PN should be evaluated and considered as another treatment target in patients with PAOD. PMID:26217631

Background Patients undergoing hemodialysis frequently report pain with multifactorial causes, not limited to that experienced directly from hemodialysis treatment. Their pain may be nociceptive, neuropathic, somatic or visceral in nature. Despite this, pain in this population remains under-recognized and under-treated. Although several tools have been used to measure pain in patients undergoing hemodialysis as reported in the literature, none of them have been validated specifically in this population. The objective for this review was to compare and contrast these pain assessment tools and discuss their clinical utility in this patient population. Methods To identify pain assessment tools studied in patients undergoing hemodialysis, a literature search was performed in PubMed and Medline. An expert panel of dialysis and pain clinicians reviewed each tool. Each pain assessment tool was assessed on how it is administered and scored, its psychometric properties such as reliability, validity and responsiveness to change, and its clinical utility in a hemodialysis population. Brief Pain Inventory, McGill Pain Questionnaire, Pain Management Index, Edmonton Symptom Assessment System, Visual Analogue Scale and Faces Pain Scale were evaluated and compared. Results This assessment will help clinicians practicing in nephrology to determine which of these pain assessment tools is best suited for use in their individual clinical practice. PMID:25852910

Objectives: High doses of chemotherapy generate DNA damage in patients undergoing bone marrow transplantation (BMT), due to the production of reactive oxygen species (ROS). In order to evaluate the local defensive effectiveness of the patient undergoing BMT, the concentrations of the antioxidants superoxide dismutase (SOD) and uric acid (UA) were measured in saliva. Study Design: Basal saliva samples were collected from 20 patients undergoing BMT at the Oncology Department, Sanatorio Allende (Córdoba), in the stages: initial, prior to conditioning therapy (I); middle: 7 to 10 days after BMT (M) and final stage, 30 days after discharge from isolation (F). SOD levels were determined using a RANDOX kit (RANSOD superoxide dismutase manual), and for uric acid enzymatic UOD / PAP spectrophotometric method, ( Trinder Color Kit , Wiener Lab) was used. Results: 85% of the patients developed oral mucositis. SOD concentration in the M stage was significantly higher (p<0.01) compared with stage I, and it reversed in stage F. UA concentration was significantly lower (p<0.001) in stage M compared with stage I, and in stage F it recovered the initial values. Conclusions: SOD increase in stage M coincided with the appearance of mucositis, which could be interpreted as a defensive mechanism of saliva against oxidative stress produced by chemotherapy. UA decrease in stage M would favour the development of higher degrees of mucositis. Key words:Bone marrow transplantation, mucositis, superoxide dismutase, uric acid. PMID:24608218

Anxiety is the most frequent emotional reaction to the chronic somatic disease. However, little is known about anxiety and coping strategies in patients with end-stage renal disease (ESRD) undergoing renal replacement therapies (RRTs). The purpose of the study was to assess the intensity and determinants of anxiety in patients treated with different RRTs in comparison with end-stage breast cancer patients and healthy controls. The study involved (1) ESRD patients undergoing different RRTs: 32 renal transplant recipients, 31 maintenance haemodialysis and 21 chronic peritoneal dialysis patients, (2) women with end-stage breast cancer (n = 25) and (3) healthy persons (n = 55). We used State-Trait Anxiety Inventory, Scale of Personal Religiousness, Mental Adjustment to Cancer Scale, Rotterdam Symptom Checklist with reference to medical history. The data thus obtained were analysed using the analysis of variance, the Tukey's HSD post hoc test and Spearman's rank correlation coefficient. Both ESRD and breast cancer patients revealed higher level of anxiety state and trait than healthy controls; however, there was no statistically significant difference found between both findings. There was a tendency towards higher levels of anxiety state in breast cancer patients when compared to ESRD patients undergoing the RRT treatment and for both groups non-constructive coping strategies correlated with the levels of anxiety state. With ESRD patients undergoing RRTs, the intensity of anxiety state did not depend on the mode of treatment but on the correlation between the levels of anxiety and the general quality of their life, psychological condition and social activity. In patients with advanced somatic disease (ESRD and end-stage breast cancer), non-constructive strategies of coping with the disease require further evaluation and possibly psychological support.

The aim of the study was to investigate the frequency and characteristics of peripheral nervous system (PNS) and central nervous system (CNS) involvement in COPD. The study included 41 COPD patients and 41 healthy volunteers. Electrophysiological studies were carried out: electromyography (EMG) and visual evoked potentials (VEPs). The median nerve, ulnar nerve, common peroneal nerve, and tibial nerve were evaluated for latency, amplitude, and conduction velocity. The mean age of patients with COPD was 61.8 years and disease duration 10.3 years. There was no difference between patient and control groups in terms of age, BMI, smoking status, or biochemical parameters. Upon VEP examination, latencies were significantly prolonged and amplitudes shortened in the patient group compared to the control group. In EMG measurements, conduction velocity and amplitudes in all nerves were low in the patient group. Similarly, latencies in all nerves were higher in patients with COPD. Central and peripheral nervous system involvement could develop in patients with moderate-severe COPD, and these patients should be monitored for neuropathic changes in combination with neurological examination.

Evaluation of Peripheral Blood Circulation Disorder in Scleroderma Patients Using an Optical Sensor with a Pressurization Mechanism

Blood circulation function of peripheral blood vessels in skin dermis was evaluated employing an optical sensor with a pressurization mechanism using the blood outflow and reflow characteristics. The device contains a light source and an optical sensor. When applied to the skin surface, it first exerts the primary pressure (higher than the systolic blood pressure), causing an outflow of blood from the dermal peripheral blood vessels. After two heartbeats, the pressure is lowered (secondary pressure) and blood reflows into the peripheral blood vessels. Hemoglobin concentration, which changes during blood outflow and reflow, is derived from the received light intensity using the Beer–Lambert law. This method was evaluated in 26 healthy female volunteers and 26 female scleroderma patients. In order to evaluate the blood circulation function of the peripheral blood vessels of scleroderma patients, pressurization sequence which consists of primary pressure followed by secondary pressure was adopted. Blood reflow during the first heartbeat period after applying the secondary pressure of 40mmHg was (mean±SD) 0.059±0.05%mm for scleroderma patients and 0.173±0.104%mm for healthy volunteers. Blood reflow was significantly lower in scleroderma patients than in healthy volunteers (p<0.05). This result indicates that the information necessary for assessing blood circulation disorder of peripheral blood vessels in scleroderma patients is objectively obtained by the proposed method.

Retinitis Pigmentosa is a common form of hereditary retinal degeneration constituting the largest Mendelian genetic cause of blindness in the developed world. It has been widely suggested that oxidative stress possibly contributes to its pathogenesis. We measured the levels of total antioxidant capacity, free nitrotyrosine, thiobarbituric acid reactive substances (TBARS) formation, extracellular superoxide dismutase (SOD3) activity, protein, metabolites of the nitric oxide/cyclic GMP pathway, heme oxygenase-I and inducible nitric oxide synthase expression in aqueous humor or/and peripheral blood from fifty-six patients with retinitis pigmentosa and sixty subjects without systemic or ocular oxidative stress-related disease. Multivariate analysis of covariance revealed that retinitis pigmentosa alters ocular antioxidant defence machinery and the redox status in blood. Patients with retinitis pigmentosa present low total antioxidant capacity including reduced SOD3 activity and protein concentration in aqueous humor. Patients also show reduced SOD3 activity, increased TBARS formation and upregulation of the nitric oxide/cyclic GMP pathway in peripheral blood. Together these findings confirmed the hypothesis that patients with retinitis pigmentosa present reduced ocular antioxidant status. Moreover, these patients show changes in some oxidative-nitrosative markers in the peripheral blood. Further studies are needed to clarify the relationship between these peripheral markers and retinitis pigmentosa. PMID:24069283

Acromegaly is known to affect peripheral nervous system (PNS) causing carpal tunnel syndrome (CTS) and polyneuropathy. The frequency of these disorders and the evaluation methods vary among studies. In the present study, we aimed to examine PNS of acromegaly patients under somatostatin analogue (SSA) therapy. Forty-eight acromegaly patients (26 F/22 M, 45.58 ± 11.6 years) under SSA treatment and 44 healthy controls (25 F/19 M, 47.46 ± 8.7 years) were assessed by symptom questionnaires, neurologic examination and electrophysiological studies. 87.5 % of the acromegaly patients had at least one abnormal finding regarding PNS. With the incorporation of palm-wrist median nerve conduction velocity method, we detected CTS in 50 % of patients. Polyneuropathy was less frequent (29.2 %). Both conditions were independent from the coexisting diabetes mellitus (p = 0.22 for CTS, p = 0.71 for polyneuropathy). Polyneuropathy but not CTS was more common among biochemically uncontrolled acromegaly patients rather than those under control (p = 0.03; p = 0.68, respectively). Our findings emphasize the high prevalence of peripheral nervous system involvement in acromegaly patients under SSA therapy and importance of neurological evaluation of these patients. Early diagnosis and treatment of the disease may reduce the PNS involvement.

The present study is an evaluation of the efficacy of endovascular treatment in emergency setting for patients with acute peripheral and visceral arterial injury secondary to penetrating or blunt trauma. Twelve patients (11 men) aged 35.8±11.3 years (range: 18-56 years) with penetrating or blunt trauma who underwent endovascular treatment in our department between March 2010 and June 2014 for peripheral and visceral arterial injury were retrospectively reviewed. Selective coil embolization was performed on 11 patients and particle embolization of the injured vessel was performed on 1 patient. Criteria for endovascular treatment included active extravasation or pseudoaneurysm on contrast-enhanced computed tomography and decrease in hemoglobin level or temporary hemodynamic instability. Arterial injuries were secondary to penetrating injury due to gunshot wound in 4 patients and stab wound in 5, and blunt abdominal injury as result of traffic accident in 3 patients. Traumatic lesions were in the right hepatic artery (n=3), left hepatic (n=2), right hepatic and right renal (n=1), left inferior epigastric (n=2), left facial (n=1), anterior tibial (n=1), and deep femoral (n=1) arteries. Technical success with no procedural complications was seen in all cases. Two patients died due to coexisting injuries on 29th and 43rd days of hospitalization. Median hospitalization period was 6.0 days (range: 1-43 days) and mean intensive care unit hospitalization was 7.7 days (range: 0-43 days). In our experience, endovascular treatment was a safe and effective option for acute traumatic peripheral and visceral arterial lesions.

The prevention and treatment of peritonitis in patients undergoing peritoneal dialysis is often complicated by several factors, including nephrotoxicity, requirement for hospitalization, parenteral antibiotic therapy, and infection caused by resistant microorganisms. Ciprofloxacin, a new carboxyquinolone derivative, may offer the advantages of oral administration, a broad spectrum of antibacterial activity, and safety for the management of these patients. The pharmacokinetics of ciprofloxacin in serum and peritoneal fluid of eight adult patients undergoing chronic ambulatory peritoneal dialysis (CAPD) were investigated. Each patient ingested a single 750-mg dose of ciprofloxacin, and drug concentrations were measured by high-pressure liquid chromatography in serum and peritoneal fluid for 48 h after the dose. Serum concentrations reached a mean peak of 3.6 micrograms/ml 1 to 2 h after the oral dose. The mean terminal serum half-life was 16.8 h, and the mean peritoneal fluid/serum concentration ratio was 0.64. The mean peak ciprofloxacin concentration in peritoneal fluid was 1.3 micrograms/ml, and the bioactivity of the drug in peritoneal fluid was confirmed. These data indicated that therapeutic concentrations of ciprofloxacin against bacterial pathogens commonly associated with peritonitis in CAPD patients may be achievable in the peritoneal fluid after oral administration to patients undergoing CAPD. In addition, the pharmacokinetic data provide guidelines for further clinical studies of oral ciprofloxacin in CAPD patients. PMID:2944477

This narrative review will present and discuss clinical data from 16 cross-sectional and 6 longitudinal studies examining the relationship between body mass index (BMI), symptoms of depression and peripheral inflammation. Our aim is to determine which of obesity and depression contributes best to the peripheral low-grade inflammation frequently associated to both conditions. Studies including a complete evaluation of inflammatory markers are scarce and high levels of interleukin-6 (IL-6) and C-reactive protein (CRP) are the most consistent findings associated with obesity and symptoms of depression. Among the cross-sectional studies, seven studies, including a total of 9421 individuals, pointed to BMI as the major factor associated with systemic low-grade inflammation. However, in four studies, including 16,837 individuals, CRP levels remained associated with the symptoms of depression even after correction for BMI, suggestion that in the absence of overweight or obesity other sources of peripheral inflammation might contribute to presence of depressive symptoms. Additionally, another five studies, including 5569 individuals failed to find an association between depression and peripheral inflammation, reinforcing the heterogeneity of this condition. In the longitudinal data, changes in BMI were associated with a reduction in depressive scores at follow-up, after bariatric surgery or after diet. In four longitudinal studies, high levels of CRP were found to be associated with depression even after adjustment for BMI and weight loss, further corroborating the idea that other sources of peripheral inflammation might contribute to depressive symptoms. Thus it seems that both obesity and depressive symptoms can contribute to peripheral inflammation, and once installed the presence of inflammation can contribute to several behavioral alterations that reinforce the cyclic pattern of co-occurrence observed in patients with obesity and MDD.

Background: Problems regarding bowel elimination are quite common in patients undergoing abdominal surgery. Objectives: To determine constipation risk before the surgery, bowel elimination during postoperative period, and the factors affecting bowel elimination. Patients and Methods: This is a cross-sectional study. It was conducted in a general surgery ward of a university hospital in Zonguldak, Turkey between January 2013 and May 2013. A total of 107 patients were included in the study, who were selected by convenience sampling. Constipation Risk Assessment Scale (CRAS), patient information form, medical and nursing records were used in the study. Results: The mean age of the patients was found to be 55.97 ± 15.74 (year). Most of the patients have undergone colon (37.4%) and stomach surgeries (21.5%). Open surgical intervention (83.2%) was performed on almost all patients (96.3%) under general anesthesia. Patients were at moderate risk for constipation with average scores of 11.71 before the surgery. A total of 77 patients (72%) did not have bowel elimination problem during postoperative period. The type of the surgery (P < 0.05), starting time for oral feeding after the surgery (P < 0.05), and mobilization (P < 0.05) were effective on postoperative bowel elimination. Conclusions: There is a risk for constipation after abdominal surgery. Postoperative practices are effective on the risk of constipation. PMID:26380107

The relationship between vitamin B12 deficiency and peripheral neuropathy has been shown in a number of previous studies. Metformin is the indispensable first-line treatment for type 2 diabetes mellitus (DM) worldwide. One of the adverse effects of the use of metformin is vitamin B12 deficiency. In the present study, we investigated the relationship between vitamin B12 deficiency and peripheral neuropathy due to the use of metformin. Patient's laboratory and electromyography (EMG) data were retrospectively reviewed. Patients with no EMG report and other necessary information were excluded from the study. Eighty-six patients with type 2 DM using metformin were included in the study. Of these patients, 26 were males and 60 were females. The mean age of the patients was 55.1±7.7 years. The mean body mass index of the patients was 29.1±9.01 kg/m 2 . The mean HbA1c level of the patients was 8.6%±2.1%. The mean duration of diabetes was 8.02±5.4 years. The incidence of vitamin B12 deficiency was 38.4%. Peripheral neuropathy was detected in 33.7% patients. There was no statistically significant difference in vitamin B12 levels between patients with peripheral neuropathy and those without peripheral neuropathy (p=0.64). Therefore, it can be concluded that the lack of vitamin B12 secondary to the use of metformin did not significantly increase the frequency of peripheral neuropathy.

Purpose. To report the 2-year results after hybrid (combined surgical-endovascular) therapy in patients with complex peripheral multifocal steno-obstructive vascular disease. Methods. From September 2001 through April 2003, 47 combined surgical-endovascular procedures were performed in a single session in 44 patients with peripheral occlusive artery disease. Although the common femoral artery is usually treated with open surgery, endoluminal procedures were performed upward in 23 patients (group A), distally in 18 patients (group B), and both upward and downward of the area treated with open surgery in 3 patients (group C). Patients underwent clinical assessment and color duplex ultrasonography examination at 1,more » 3, 6, 12, 18, and 24 months after the procedure. Results. The technical success rate was 100%. Two patients died, at 2 and 19 months after treatment, respectively, both from myocardial infarction. Primary and primary-assisted patency rates were 86.2% and 90.8% at 6 months and 79.1% and 86.1% at 24 months, respectively. Thirty-three patients remained free of symptoms, without any secondary interventions, which corresponded to a primary patency rate of 78.6% (33 of 42). Conclusion. Combined therapy simplifies and allows the one-step treatment of patients with complex peripheral multifocal steno-obstructive vascular disease that has indications for revascularization, and it provides excellent long-term patency rates.« less

As life expectancy increases, it is expected that 60% of all cases of cancer will be detected in elderly patients in the next two decades. Cancer treatment for older persons is complicated by a number of factors, thus negatively affecting patients' quality of life. The purpose of this study is to investigate quality of life in elderly cancer patients undergoing chemotherapy. This study was descriptive and non-experimental. It was conducted in one large hospital in a major city of Northern Greece. The sample was convenience comprising 53 elderly cancer patients undergoing cycle 3 chemotherapy. The data was collected using the Functional Assessment of Cancer Therapy scale and included questions related to demographic and clinical characteristics. The majority of participants were men (n = 27, 50.9%) who were married (n = 32, 79.5%). Their mean age was 70.07 ± 3.60. Almost half of the sample (n = 30, 56.6%) had colon cancer. There was a statistical significant difference between men and women pertaining to physical wellbeing (p = 0.004) and overall quality of life (p < 0.001). When comparing each subscale with the patients' marital status it was found that there was a statistical difference with respect to social/family wellbeing (p = 0.029), functional wellbeing (p = 0.09) and overall quality of life (p < 0.001). Moreover, the type of cancer affected overall quality of life (p < 0.001) and social/family wellbeing (p = 0.029). These findings call attention to quality of life and its related factors in elderly cancer patients. It is highly recommended to envisage measures for improving quality of life in this group of cancer patients.

Brain natriuretic peptide (BNP) levels correlate with prognosis in patients with cardiac disease and may be useful in the risk stratification of cardiac patients undergoing noncardiac surgery (NCS). The objective of this study was to examine whether BNP levels predict perioperative events in cardiac patients undergoing NCS. Patients undergoing NCS with at least 1 of the following criteria were included: a clinical history of congestive heart failure (CHF), ejection fraction <40%, or severe aortic stenosis. All patients underwent echocardiography and measurement of BNP performed using the ADVIA-Centaur BNP assay (Bayer HealthCare). Clinical endpoints were death, myocardial infarction or pulmonary congestion requiring intravenous diuretics at 30 days of follow-up. Forty-four patients were entered into the study; 15 patients (34%) developed cardiac postoperative complications. The mean BNP level was 1,366 +/- 1,420 pg/ml in patients with events and 167 +/- 194 pg/ml in patients without events, indicating a highly significant difference (p < 0.001). The ROC area under the curve was 0.91 (95% CI 0.83-0.99) with an optimal cutoff of >165 pg/ml (100% sensitivity, 70% specificity). BNP levels may predict perioperative complications in cardiac patients undergoing NCS, and the measurement of BNP should be considered to assess the preoperative cardiac risk. (c) 2007 S.

Prosthetic joint infection (PJI) is a complication with serious repercussions and its main cause is Staphylococcus aureus. The purpose of this study is to determine whether decolonization of S.aureus carriers helps to reduce the incidence of PJI by S.aureus. An S.aureus screening test was performed on nasal carriers in patients undergoing knee or hip arthroplasty between January and December 2011. Patients with a positive test were treated with intranasal mupirocin and chlorhexidine soap 5 days. The incidence of PJI was compared with patients undergoing the same surgery between January and December 2010. A total of 393 joint replacements were performed in 391 patients from the control group, with 416 joint replacements being performed in the intervention group. Colonization study was performed in 382 patients (91.8%), of which 102 were positive (26.7%) and treated. There was 2 PJI due S.aureus compared with 9 in the control group (0.5% vs 2.3%, odds ratio [OR]: 0.2, 95% confidence interval [CI]: 0.4 to 2.3, P=.04). In our study, the detection of colonization and eradication of S.aureus carriers achieved a significant decrease in PJI due to S.aureus compared to a historical group.

Background The definition of neuropathic pain has recently been changed by the International Association for the Study of Pain. This means that conditions such as fibromyalgia cannot, as sometimes discussed, be included in the neuropathic pain conditions. However, fibromyalgia and peripheral neuropathic pain share common clinical features such as spontaneous pain and hypersensitivity to external stimuli. Therefore, it is of interest to directly compare the conditions. Material and methods In this study we directly compared the pain modulation in neuropathic pain versus fibromyalgia by recording responses to a cold pressor test in 30 patients with peripheral neuropathic pain, 28 patients with fibromyalgia, and 26 pain-free age-and gender-matched healthy controls. Patients were asked to rate their spontaneous pain on a visual analog scale (VAS (0-100 mm) immediately before and immediately after the cold pressor test. Furthermore the duration (s) of extremity immersion in cold water was used as a measure of the pain tolerance threshold, and the perceived pain intensity at pain tolerance on the VAS was recorded on the extremity in the water after the cold pressor test. In addition, thermal (thermo tester) and mechanical stimuli (pressure algometer) were used to determine sensory detection, pain detection, and pain tolerance thresholds in different body parts. All sensory tests were done by the same examiner, in the same room, and with each subject in a supine position. The sequence of examinations was the following: (1) reaction time, (2) pressure thresholds, (3) thermal thresholds, and (4) cold pressor test. Reaction time was measured to ensure that psychomotoric inhibitions did not influence pain thresholds. Results Pain modulation induced by a cold pressor test reduced spontaneous pain by 40% on average in neuropathic pain patients, but increased spontaneous pain by 2.6% in fibromyalgia patients. This difference between fibromyalgia and neuropathic pain patients was

Objective: The objective of this study was to evaluate the peripheral binocular visual field (PBVF) in patients with glaucoma using the threshold strategy of Humphrey Field Analyzer. Methods: We conducted a case-control pilot study in which we enrolled 59 patients with glaucoma and 20 controls. All participants were evaluated using a custom PBVF test and central 24° monocular visual field tests for each eye using the threshold strategy. The central binocular visual field (CBVF) was predicted from the monocular tests using the most sensitive point at each field location. The glaucoma patients were grouped according to Hodapp classification and age. The PBVF was compared to controls and the relationship between the PBVF and CBVF was tested. Results: The areas of frame-induced artefacts were determined (over 50° in each temporal field, 24° superiorly and 45° inferiorly) and excluded from interpretation. The patients presented a statistically significant generalized decrease of the peripheral retinal sensitivity compared to controls for Hodapp initial stage - groups aged 50-59 (t = 11.93 > 2.06; p < 0.05) and 60-69 (t = 7.55 > 2.06; p < 0.05). For the initial Hodapp stage there was no significant relationship between PBVF and CBVF (r = 0.39). For the moderate and advanced Hodapp stages, the interpretation of data was done separately for each patient. Conclusions: This pilot study suggests that glaucoma patients present a decrease of PBVF compared to controls and CBVF cannot predict the PBVF in glaucoma.

Patients undergoing lobectomy are at significantly increased risk of lung injury. One-lung ventilation is the most commonly used technique to maintain ventilation and oxygenation during the operation. It is a challenge to choose an appropriate mechanical ventilation strategy to minimize the lung injury and other adverse clinical outcomes. In order to understand the available evidence, a systematic review was conducted including the following topics: (I) protective ventilation (PV); (II) mode of mechanical ventilation [e.g., volume controlled (VCV) versus pressure controlled (PCV)]; (III) use of therapeutic hypercapnia; (IV) use of alveolar recruitment (open-lung) strategy; (V) pre-and post-operative application of positive end expiratory pressure (PEEP); (VI) Inspired Oxygen concentration; (VII) Non-intubated thoracoscopic lobectomy; and (VIII) adjuvant pharmacologic options. The recommendations of class II are non-intubated thoracoscopic lobectomy may be an alternative to conventional one-lung ventilation in selected patients. The recommendations of class IIa are: (I) Therapeutic hypercapnia to maintain a partial pressure of carbon dioxide at 50-70 mmHg is reasonable for patients undergoing pulmonary lobectomy with one-lung ventilation; (II) PV with a tidal volume of 6 mL/kg and PEEP of 5 cmH 2 O are reasonable methods, based on current evidence; (III) alveolar recruitment [open lung ventilation (OLV)] may be beneficial in patients undergoing lobectomy with one-lung ventilation; (IV) PCV is recommended over VCV for patients undergoing lung resection; (V) pre- and post-operative CPAP can improve short-term oxygenation in patients undergoing lobectomy with one-lung ventilation; (VI) controlled mechanical ventilation with I:E ratio of 1:1 is reasonable in patients undergoing one-lung ventilation; (VII) use of lowest inspired oxygen concentration to maintain satisfactory arterial oxygen saturation is reasonable based on physiologic principles; (VIII) Adjuvant drugs

Peripheral neuropathy is the most frequent disabling neuromuscular complication of burns. However, the insidious and progressive onset of burn neuropathy makes it often undiagnosed or overlooked. In our study, we reviewed the current studies on the burn-related peripheral neuropathy to summarize the morbidity, mechanism, detecting method and management of peripheral neuropathy in burn patients. Of the 1533 burn patients included in our study, 98 cases (6.39%) were presented with peripheral neuropathy. Thermal and electrical burns were the most common etiologies. Surgical procedures, especially nerve decompression, showed good effect on functional recovery of both acute and delayed peripheral neuropathy in burn patients. It is noteworthy that, for early detection and prevention of peripheral neuropathy, electrodiagnostic examinations should be performed on burn patients independent of symptoms. Still, the underlying mechanisms of burn-related peripheral neuropathy remain to be clarified. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

This work discusses the production and management of liquid radioactive wastes as excretas from patients undergoing therapy procedures with 131I radiopharmaceuticals in Spain. The activity in the sewage has been estimated with and without waste radioactive decay tanks. Two common therapy procedures have been considered, the thyroid cancer (4.14 GBq administered per treatment), and the hyperthyroidism (414 MBq administered per treatment). The calculations were based on measurements of external exposure around the 244 hyperthyroidism patients and 23 thyroid cancer patients. The estimated direct activity discharged to the sewage for two thyroid carcinomas and three hyperthyroidisms was 14.57 GBq and 1.27 GBq, respectively, per week; the annual doses received by the most exposed individual (sewage worker) were 164 microSv and 13 microSv, respectively. General equations to calculate the activity as a function of the number of patient treated each week were also obtained.

The present study evaluated the relationship between health status (HS) and peripheral muscle histochemical characteristics in chronic obstructive pulmonary disease (COPD), and identified selected independent respiratory and extrapulmonary variables that predicted the HS of these patients. Cross-sectional study. Outpatient respiratory clinic of a university hospital. We studied 29 patients (63+/-10 yrs) with a forced expiratory volume in 1s (FEV1) of 39+/-12%. All patients underwent vastus lateralis muscle biopsies for histochemical analysis. They also had spirometry, arterial blood gas analysis, body mass index (BMI), dyspnea determined with the MMRC scale and responded to the St. George's Respiratory Questionnaire (SGRQ) for HS assessment. SGRQ total score correlated with fiber type distribution. A stepwise multiple regression identified three independent predictors of SGRQ total score: type I fiber proportion, BMI, and FEV1; r = 0.78 and r2 = 0.61. These results indicate that impaired HS in COPD is related to the peripheral muscle changes characterized by less type I fibers proportion. The findings argue in favor of an important contribution of the systemic consequences on the HS in COPD independently from the airflow limitation severity, and help to explain the observation of the poor correlation between the degree of airflow limitation and SGRQ total score.

The utilization of peripheral nerve blocks in orthopaedic surgery has paralleled the rise in the number of ambulatory surgical procedures performed. Optimization of pain control in the perioperative orthopaedic patient contributes to improved patient satisfaction, early mobilization, decreased length of hospitalization, and decreased associated hospital and patient costs. Our purpose was to provide a concise, pertinent review of the use of peripheral nerve blocks in various orthopaedic procedures of the lower extremity, with specific focus on procedural anatomy, indications, patient outcome measures, and complications. We reviewed the literature and reference textbooks on commonly performed lower-extremity peripheral nerve block procedures in orthopaedic surgery, focusing on those most commonly used. The use of lower-extremity peripheral nerve blocks is a safe and effective approach to perioperative pain management. Different techniques and timing can have an important impact on patient satisfaction, and each technique has specific indications and complications. For major hip surgery, one of the most commonly used is the lumbar plexus block, which can result in early mobilization, reduced postoperative pain, and decreased opioid-associated adverse events. Associated complications include epidural spread of anesthesia, retroperitoneal hematoma formation, and postoperative falls. For arthroscopic and open knee procedures, the femoral nerve block is frequently used adjunctively. It provides improved early postoperative pain control, early mobilization with therapy, and increased patient satisfaction compared with intra-articular or intravenous opioids alone; it also provides cost savings. However, some studies have shown no significant difference in outcome measures compared with intra-articular opioids alone for arthroscopic anterior cruciate ligament reconstruction. Associated complications include nerve injury, intravascular injection, and postoperative falls. The

Forty-nine consecutive subjects with established diabetic peripheral neuropathy were treated with monochromatic near-infrared photo energy (MIRE) to determine if there was an improvement of sensation. Loss of protective sensation characterized by Semmes-Weinstein monofilament values of 4.56 and above was present in 100% of subjects (range, 4.56 to 6.45), and 42 subjects (86%) had Semmes-Weinstein values of 5.07 or higher. The ability to discriminate between hot and cold sensation was absent (54%) or impaired (46%) in both groups prior to the initiation of MIRE treatment. On the basis of Semmes-Weinstein monofilament values, 48 subjects (98%) exhibited improved sensation after 6 treatments, and all subjects had improved sensation after 12 treatments. Therefore, MIRE may be a safe, drug-free, noninvasive treatment for the consistent and predictable improvement of sensation in diabetic patients with peripheral neuropathy of the feet.

The aim of this study was to assess retrospectively the efficacy and complication rate of hindlimb peripheral nerve blocks (PNBs) in cats. Clinical records of cats that received PNBs and underwent hindlimb orthopaedic surgery from February 2010 to October 2014 were examined. Type of PNB, type and dose of local anaesthetic used, end-expiratory fraction of isoflurane (FE'Iso) administered, additional intraoperative analgesia, incidence of hypotension, postoperative opioid requirement, postoperative contralateral limb paralysis and neurological complications at the 6 week re-examination were investigated. Eighty-nine records were retrieved but only 69 were analysed. Four combinations of PNBs were used: 34 lateral preiliac (LPI) approach to lumbar plexus (LP) associated with lumbar paravertebral approach to sciatic nerve (SN); 20 LPI-LP associated with the lateral approach to SN; three LPI-LP associated with gluteal approach to SN; 12 dorsal-paravertebral (DPV) approach to LP associated with lateral SN. Levobupivacaine was used for the majority of PNBs. The mean intraoperative FE'Iso was 1.15%; hypotension was documented in 55.1% of anaesthetics, while 31.8% of cats received fentanyl and/or ketamine intraoperatively. Postoperatively, 72.7% of cats received at least one dose of opioid, while five cats required further postoperative analgesia (ketamine constant rate infusion and/or gabapentin). No cats showed contralateral limb paralysis and neurological complications at the 6 week re-examination. No differences were found when comparing the different PNBs used. PNBs contributed to perioperative anaesthesia/analgesia in cats undergoing hindlimb orthopaedic surgery. However, the clinical relevance of intraoperative hypotension needs further investigation. © The Author(s) 2015.

Emerging evidence suggested that microRNAs (miRNAs) play a causal role in cancer tumorigenesis. Aberrant expression of miRNA (miR)-139-5p has been observed in various types of cancers. The present study evaluated the relationship between miR-139-5p expression levels and prostate cancer (PCa), to assess the feasibility of using peripheral blood miR-139-5p as a potential non-invasive biomarker for PCa. Total RNA was extracted from peripheral whole blood samples from 45 PCa patients, 45 benign prostatic hyperplasia (BPH) patients and 50 healthy controls (HC). The expression of miR-139-5p was assessed by reverse transcription quantitative polymerase chain reaction. MiR-139-5p in peripheral blood was significantly higher in PCa patients than in patients with BPH and HC individuals (P<0.001). Higher miR-139-5p expression was observed to be associated with certain clinicopathological parameters, including PSA>20ng/ml (P<0.05), pathological tumor stage 3/4 (P<0.05) and Gleason score >7 (P<0.01). A receiver operating characteristic (ROC) curve analysis revealed that miR-139-5p distinguished PCa patients from BPH patients [area under the curve (AUC), 0.936; 95% CI, 0.878-0.993; P<0.001]. Peripheral blood miR-139-5p may be utilized as a potential novel non-invasive biomarker for PCa screening. © 2016 The Author(s) Published by S. Karger AG, Basel.

Diabetic patients are at high risk of foot ulcerations that may lead to limb amputations with important socio-economic impact. Peripheral vascular disease may be frequently associated in diabetes mellitus type II with its main symptom, intermittent claudication. Many studies reported the known efficacy of cilostazol in treating vascular claudication. Metalloproteinase-9 (MMP-9) seems to be a biochemical marker implicated in chronic wounds and in particular in diabetic foot ulcers. Cilostazol appears to have a lowering effect on MMP-9 levels and this may suggest a beneficial effect in order to prevent or retard the onset of foot ulcer in diabetic patients. In our study, two groups of diabetic patients with peripheral vascular disease were divided into two groups according to the presence of claudication in order to receive cilostazol. Group A (31 patients without claudication) were not eligible to receive cilostazol whereas Group B (47 patients with claudication) received cilostazol administration for 24 weeks (100 mg orally twice daily). Median follow up was of 16 months. During the follow up, 4·25% of patients of Group B and 35·48% of patients of Group A (P < 0·01) showed onset of foot ulceration. Although further randomised and controlled studies are required cilostazol seems to show beneficial effects for primary prevention of diabetic foot ulcers. © 2013 The Authors.

Hemodialysis (HD) patients have been increasing recently. Some rheumatoid arthritis (RA) patients need hemodialysis (HD), though the proportion is not high. At present, such patients are almost treated with corticosteroids and/or nonsteroidal anti-inflammatory drugs alone, even if they have a high disease activity that would require disease-modifying anti-rheumatic drug (DMARD) therapy, partly because the safety of DMARDs in RA patients with end-stage renal disease has not been confirmed. Their joint destruction would be inevitable and lead to impaired activities of daily living. As there are no guidelines for the use of DMARDs in HD patients, here I reviewed the previous reports about the treatment of DMARDs including biologics for patients with RA undergoing HD.

Reduction of cognitive function is a possible side effect after cardiac surgery using cardiopulmonary bypass. We investigated the cerebroprotective effect of piracetam on cognitive performance in patients undergoing coronary artery bypass surgery under cardiopulmonary bypass. Patients scheduled for elective, primary and isolated coronary bypass surgery were randomised either to piracetam or placebo group. The study was performed in a double blind fashion. Patients received either 12 g piracetam or placebo at the beginning of the operation. Six neuropsychological subtests from the Syndrom Kurz Test and the Alzheimer's Disease Assessment Scale were performed preoperatively and on the third postoperative day. To assess the overall cognitive function and the degree of cognitive decline across all tests after surgery we combined the six test-scores by principal component analysis. A total number of 120 patients were enrolled into the study. Preoperative overall cognitive function were not significantly different between the groups. The postoperative combined score of the neuropsychological tests showed a deterioration of cognitive function in both groups (placebo-pre: -0.06+/-0.99 vs placebo-post: -1.38+/-1.11; p<0.0005 and piracetam-pre: 0.06+/-1.02 vs piracetam-post: -0.65+/-0.93; p<0.0005). However, the piracetam patients performed significantly better compared to the placebo patients after the operation and had a less decline of overall cognitive function (p<0.0005). Piracetam has a cerebroprotective effect in patients undergoing coronary artery bypass surgery with the use of cardiopulmonary bypass. It reduces an early postoperative substantial decline of neuropsychological abilities.

This study was conducted to evaluate the effect of royal jelly on oral mucositis in patients undergoing radiotherapy and chemotherapy. The study population consisted of 103 patients undergoing radiotherapy and chemotherapy. Oral mucositis was graded according to the World Health Organization criteria, and patients were divided into 2 groups. All patients received mouthwash therapy with benzydamine hydrochloride and nystatin rinses. In addition, patients in the experimental group received royal jelly. The mean resolution time of oral mucositis in the royal jelly group was significantly shorter than that of the control group. As a result, the study results demonstrate that royal jelly administrated by a certain procedure improved the signs and symptoms of oral mucositis and markedly shortened its healing time.

Objective The endocannabinoid system (ECS) promotes weight gain and obesity-associated metabolic changes. Weight loss interventions may influence obesity-associated risk indirectly through modulation of the peripheral ECS. We investigated the effect of acute and chronic treatment with sibutramine on components of the peripheral ECS. Methods and Procedures Twenty obese otherwise healthy patients received randomized, double-blind, crossover treatment with placebo and 15 mg/day sibutramine for 5 days each, followed by 12 weeks open-label sibutramine treatment. We determined circulating anandamide and 2-arachidonoylglycerol and expression levels of endocannabinoid genes in subcutaneous abdominal adipose tissue biopsies. Results Body weight was stable during the acute treatment period and decreased by 6.0 ± 0.8 kg in those patients completing 3 months of sibutramine treatment (P < 0.05). Circulating endocannabinoids and the expression of ECS genes did not change with acute or chronic sibutramine treatment. Discussion The ECS is activated in obesity. We did not find any influence of 5% body weight loss induced by sibutramine on circulating levels of endocannabinoids and adipose-tissue expression of endocannabinoid genes in obese subjects. These data confirm our previous findings on dietary weight loss and suggest that the dysregulation of the ECS may be a cause rather than a consequence of obesity. PMID:18356837

AIM: To evaluate the effect of β-blockade on angiotensins in the splanchnic and peripheral circulation of cirrhotic patients and also to compare hemodynamic parameters during liver transplantation according to propranolol pre-treatment or not. METHODS: Patients were allocated into two groups: outpatients with advanced liver disease(LD) and during liver transplantation(LT). Both groups were subdivided according to treatment with propranolol or not. Plasma was collected through peripheral venipuncture to determine plasma renin activity(PRA), Angiotensin(Ang) I, Ang II, and Ang-(1-7) levels by radioimmunoassay in LD group. During liver transplantation, hemodynamic parameters were determined and blood samples were obtained from the portal vein to measure renin angiotensin system(RAS) components. RESULTS: PRA, Ang I, Ang II and Ang-(1-7) were significantly lower in the portal vein and periphery in all subgroups treated with propranolol as compared to non-treated. The relationships between Ang-(1-7) and Ang I levels and between Ang II and Ang I were significantly increased in LD group receiving propranolol. The ratio between Ang-(1-7) and Ang II remained unchanged in splanchnic and peripheral circulation in patients under β-blockade, whereas the relationship between Ang II and Ang I was significantly increased in splanchnic circulation of LT patients treated with propranolol. During liver transplantation, cardiac output and index as well systemic vascular resistance and index were reduced in propranolol-treated subgroup. CONCLUSION: In LD group, propranolol treatment reduced RAS mediators, but did not change the ratio between Ang-(1-7) and Ang II in splanchnic and peripheral circulation. Furthermore, the modification of hemodynamic parameters in propranolol treated patients was not associated with changes in the angiotensin ratio. PMID:19058308

Peripheral myelin protein (PMP-22) gene aneuploidy results in Charcot-Marie-Tooth disease Type 1A (CMT1A) and the Hereditary Neuropathy with Liability to Pressure Palsy (HNPP) in Japanese patients as well as Caucasian Americans. Charcot-Marie-Tooth disease (CMT), the most common genetic neuropathy, results when expression of one of at least seven genes is defective. CMT1A, about half of all CMT mutations, is usually associated with a duplication spanning the peripheral myelin protein-22 gene on distal chromosome band 17p11.2. Autosomal dominant HNPP (hereditary pressure and sensory neuropathy, HPSN) results from a deletion of the CMT1A gene region. Multicolor in situ hybridization with PMP-22 genemore » region probe characterized HNPP deletion reliably and detected all different size duplications reported previously. In summary, 72% of 28 Japanese CMT1 (HMSNI) patients tested had the CMT1A duplication, while none of the CMT2 (HMSNII) or CMT3 (HMSNIII) patients had a duplication. Three cases of HNPP were identified by deletion of the CMT1A gene region on chromosome 17p. HNPP and CMT1A have been reported to result simultaneously from the same unequal recombination event. The lower frequency of HNPP compared to CMT1A suggests that HNPP patients have a lower reproductive fitness than CMT1A patients. This result, along with a CMT1A duplication found in an Asian Indian family, demonstrates the broad geographic distribution and high frequency of PMP-22 gene aneuploidy.« less

We aimed to determine the radiation doses delivered to patients undergoing general examinations using computed or digital radiography systems in Turkey. Radiographs of 20 patients undergoing posteroanterior chest X-ray and of 20 patients undergoing anteroposterior kidney-ureter-bladder radiography were evaluated in five X-ray rooms at four local hospitals in the Ankara region. Currently, almost all radiology departments in Turkey have switched from conventional radiography systems to computed radiography or digital radiography systems. Patient dose was measured for both systems. The results were compared with published diagnostic reference levels (DRLs) from the European Union and International Atomic Energy Agency. The average entrance surface doses (ESDs) for chest examinations exceeded established international DRLs at two of the X-ray rooms in a hospital with computed radiography. All of the other ESD measurements were approximately equal to or below the DRLs for both examinations in all of the remaining hospitals. Improper adjustment of the exposure parameters, uncalibrated automatic exposure control systems, and failure of the technologists to choose exposure parameters properly were problems we noticed during the study. This study is an initial attempt at establishing local DRL values for digital radiography systems, and will provide a benchmark so that the authorities can establish reference dose levels for diagnostic radiology in Turkey.

OBJECTIVE: The relationship between vitamin B12 deficiency and peripheral neuropathy has been shown in a number of previous studies. Metformin is the indispensable first-line treatment for type 2 diabetes mellitus (DM) worldwide. One of the adverse effects of the use of metformin is vitamin B12 deficiency. In the present study, we investigated the relationship between vitamin B12 deficiency and peripheral neuropathy due to the use of metformin. METHODS: Patient’s laboratory and electromyography (EMG) data were retrospectively reviewed. Patients with no EMG report and other necessary information were excluded from the study. RESULTS: Eighty-six patients with type 2 DM using metformin were included in the study. Of these patients, 26 were males and 60 were females. The mean age of the patients was 55.1±7.7 years. The mean body mass index of the patients was 29.1±9.01 kg/m2. The mean HbA1c level of the patients was 8.6%±2.1%. The mean duration of diabetes was 8.02±5.4 years. The incidence of vitamin B12 deficiency was 38.4%. Peripheral neuropathy was detected in 33.7% patients. There was no statistically significant difference in vitamin B12 levels between patients with peripheral neuropathy and those without peripheral neuropathy (p=0.64). CONCLUSION: Therefore, it can be concluded that the lack of vitamin B12 secondary to the use of metformin did not significantly increase the frequency of peripheral neuropathy. PMID:29270571

To systematically analyze published randomized trials on the effectiveness of preoperative prophylactic antibiotics in patients undergoing breast surgical procedures. Trials on the effectiveness of preoperative prophylactic antibiotics in patients undergoing breast surgery were selected and analyzed to generate summated data (expressed as risk ratio [RR]) by using RevMan 5.0. Nine randomized controlled trials encompassing 3720 patients undergoing breast surgery were retrieved from the electronic databases. The antibiotics group comprised a total of 1857 patients and non-antibiotics group, 1863 patients. There was no heterogeneity [χ(2) = 7.61, d.f. = 7, p < 0.37; I(2) = 8%] amongst trials. Therefore, in the fixed-effects model (RR, 0.64; 95% CI, 0.50-0.83; z = 3.48; p < 0.0005), the use of preoperative prophylactic antibiotics in patients undergoing breast surgical procedures was statistically significant in reducing the incidence of surgical site infection (SSI). Furthermore, in the fixed-effects model (RR, 1.30; 95% CI, 0.89-1.90; z = 1.37; p < 0.17), adverse reactions secondary to the use of prophylactic antibiotics was not statistically significant between the two groups. Preoperative prophylactic antibiotics significantly reduce the risk of SSI after breast surgical procedures. The risk of adverse reactions from prophylactic antibiotic administration is not significant in these patients. Therefore, preoperative prophylactic antibiotics in breast surgery patients may be routinely administered. Further research is required, however, on risk stratification for SSI, timing and duration of prophylaxis, and the need for prophylaxis in patients undergoing breast reconstruction versus no reconstruction. © 2012 Wiley Periodicals, Inc.

Background Silent/asymptomatic peripheral artery disease may occur in patients with chronic obstructive pulmonary disease, but it is poorly investigated. The primary aim of this study was to evaluate in chronic obstructive pulmonary disease patients the impact of asymptomatic/silent peripheral artery disease on maximal exercise capacity; the secondary aim was to search for predictors of peripheral artery disease. Methods We prospectively enrolled chronic obstructive pulmonary disease outpatients. Data on anthropometric characteristics, lung function, cardiopulmonary exercise test and ankle-brachial index were recorded. The cut-off of ankle-brachial index used to define patients with peripheral artery disease was ≤0.90. Results We studied 47 patients and found 24 patients (51%) who showed peripheral artery disease. As compared to patients without peripheral artery disease, patients with peripheral artery disease had lower values of peak oxygen uptake, peak workload, energy expenditure (metabolic equivalents) and heart rate recovery, but showed the same degree of airflow obstruction and static and dynamic hyperinflation. In a multivariate linear regression model performed to identify variables predicting metabolic equivalents, ankle-brachial index (β 2.59; 95% confidence interval 0.51-4.67; p = 0.016) was an independent variable. In the search for predictors of peripheral artery disease, heart rate recovery (odds ratio 8.80; 95% confidence interval 1.30-59.35; p = 0.026) increased the risk of peripheral artery disease, whereas metabolic equivalents (odds ratio 0.50; 95% confidence interval 0.26-0.94, p = 0.033) and inhaled corticosteroids+long-acting β 2 agonists (odds ratio 0.13; 95% confidence interval 0.02-0.83; p = 0.030) reduced this risk. Conclusions In chronic obstructive pulmonary disease outpatients, asymptomatic/silent peripheral artery disease affects the maximal exercise capacity regardless of airflow obstruction and lung

The Peripheral Artery Questionnaire (PAQ), as developed in US English, is a validated scale to evaluate the health status of patients with peripheral artery disease (PAD). The aim of this study was to translate the PAQ into Korean and to evaluate its reliability and validity. A multi-step process of forward-translation, reconciliation, consultation with the developer, back-translation and proofreading was conducted. The test-retest reliability was evaluated at a 2-week interval using the intra-class correlation coefficient (ICC). The validity was assessed by identifying associations between Korean PAQ (KPAQ) scores and Korean Health Assessment Questionnaire (KHAQ) scores. A total of 100 PAD patients were enrolled: 63 without and 37 with severe claudication. The reliability of the KPAQ was adequate, with an ICC of 0.71. There were strong correlations between KPAQ's subscales. Cronbach's alpha for the summary score was 0.94, indicating good internal consistency and congruence with the original US version. The validity was supported by a significant correlation between the total KHAQ score and KPAQ physical function, stability, symptom, social limitation and quality of life scores (r = -0.24 to -0.90; p < 0.001) as well as between the KHAQ walking subscale and the KPAQ physical function score (r = -0.55, p < 0.001). Our results indicate that the KPAQ is a reliable, valid instrument to evaluate the health status of Korean patients with PAD.

Context Myocardial perfusion imaging (MPI) is the single medical test with the highest radiation burden to the US population. While many patients undergoing MPI receive repeat MPI testing, or additional procedures involving ionizing radiation, no data are available characterizing their total longitudinal radiation burden and relating radiation burden with reasons for testing. Objective To characterize procedure counts, cumulative estimated effective doses of radiation, and clinical indications, for patients undergoing MPI. Design, Setting, Patients Retrospective cohort study evaluating, for 1097 consecutive patients undergoing index MPI during the first 100 days of 2006 at Columbia University Medical Center, all preceding medical imaging procedures involving ionizing radiation undergone beginning October 1988, and all subsequent procedures through June 2008, at that center. Main Outcome Measures Cumulative estimated effective dose of radiation, number of procedures involving radiation, and indications for testing. Results Patients underwent a median (interquartile range, mean) of 15 (6–32, 23.9) procedures involving radiation exposure; 4 (2–8, 6.5) were high-dose (≥3 mSv, i.e. one year's background radiation), including 1 (1–2, 1.8) MPI studies per patient. 31% of patients received cumulative estimated effective dose from all medical sources >100mSv. Multiple MPIs were performed in 39% of patients, for whom cumulative estimated effective dose was 121 (81–189, 149) mSv. Men and whites had higher cumulative estimated effective doses, and there was a trend towards men being more likely to undergo multiple MPIs than women (40.8% vs. 36.6%, Odds ratio 1.29, 95% confidence interval 0.98–1.69). Over 80% of initial and 90% of repeat MPI exams were performed in patients with known cardiac disease or symptoms consistent with it. Conclusion In this institution, multiple testing with MPI was very common, and in many patients associated with very high cumulative

Patients often resort to religious and spiritual activities to cope with physical and mental challenges. The effect of spiritual coping on overall health, adaptation and health-related quality of life among patients undergoing haemodialysis (HD) is well documented. Thus, it is essential to establish a valid and reliable instrument that can assess both the religious and non-religious coping methods in patients undergoing HD. This study aimed to assess the validity and reliability of the Spiritual Coping Strategies Scale Arabic version (SCS-A) in Saudi patients undergoing HD. A convenience sample of 60 Saudi patients undergoing HD was recruited for this descriptive, cross-sectional study. Data were collected between May and June 2015. Forward-backward translation was used to formulate the SCS-A. The SCS-A, Muslim Religiosity Scale and the Quality of Life Index Dialysis Version III were used to procure the data. Internal consistency reliability, stability reliability, factor analysis and construct validity tests were performed. Analyses were set at the 0.05 level of significance. The SCS-A showed an acceptable internal consistency and strong stability reliability over time. The EFA produced two factors (non-religious and religious coping). Satisfactory construct validity was established by the convergent and divergent validity and known-groups method. The SCS-A is a reliable and valid tool that can be used to measure the religious and non-religious coping strategies of patients undergoing HD in Saudi Arabia and other Muslim and Arabic-speaking countries. © 2016 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Digital ischemia is commonly found in patients with scleroderma and has been shown to respond to peripheral digital sympathectomy. While favorable long- and intermediate-term results have been documented in the literature, minimal objective data are available and the mechanism of surgical sympathectomy has not been entirely elucidated. Patients with digital ischemia secondary to Raynaud's phenomenon that had undergone peripheral sympathectomy surgery between 2001 and 2009 were identified and contacted for participation. Radial artery Doppler ultrasound studies were performed and compared to those done at the time of their sympathectomy. Of 11 patients treated over a 9-year period, only two patients were available for detailed follow-up analysis. Four patients were deceased, and two were lost to follow-up. Four of the five remaining patients reported excellent use of the hand and no significant episodes of digital ischemia. Of the two patients studied, functional results were favorable and pain was markedly improved despite worsening of the digital flow resistance over time. We conclude that peripheral digital sympathectomy may provide favorable long-term results in patients with digital ischemia from autoimmune causes, although this intervention should be considered in the early stages once ischemic symptoms manifest. Interestingly, Doppler data did not appear to correlate with functional status and symptom severity in these two patients. Further research, particularly prospective studies, is warranted to guide clinical decisions in this patient population.

Plerixafor, a recently approved peripheral blood progenitor cell mobilizing agent, is often added to granulocyte-colony stimulating factor (G-CSF) to mobilize peripheral blood progenitor cells in patients with lymphoma or myeloma who cannot mobilize enough CD34+ cells with G-CSF alone to undergo autologous stem cell transplantation. However, data are lacking regarding the feasibility and efficacy of just-in-time plerixafor in combination with chemotherapy and G-CSF. We reviewed the peripheral blood stem cell collection data of 38 consecutive patients with lymphoma (Hodgkin's and non-Hodgkin's) and multiple myeloma who underwent chemomobilization and high-dose G-CSF and just-in-time plerixafor to evaluate the efficacy of this treatment combination. All patients with multiple myeloma and all but one patient with lymphoma collected the minimum required number of CD34+ cells to proceed with autologous stem cell transplantation (>2 × 10(6) /kg of body weight). The median CD34+ cell dose collected in patients with non-Hodgkin lymphoma was 4.93 × 10(6) /kg of body weight. The median CD34+ cell dose collected for patients with multiple myeloma was 8.81 × 10(6) /kg of body weight. Plerixafor was well tolerated; no grade 2 or higher non-hematologic toxic effects were observed. Copyright © 2013 Wiley Periodicals, Inc.

Recent reports suggested dendritic cells (DCs) to be important players in the pathogenesis of autoimmune thyroid processes in humans. However, there are virtually no data addressing the influence of thyroid autoaggression-associated disturbances of thyrometabolic conditions on DCs biology. The aim of the study was to evaluate the influence of L-thyroxine supplementation on conventional and plasmacytoid peripheral blood DCs subtypes in patients with hypothyroidism due to Hashimoto's thyroiditis (HT). Eighteen patients with newly diagnosed hypothyroidism due to HT were included into the study. All patients received L-thyroxine treatment with doses adjusted to reach euthyroidism. Peripheral blood DC subtypes structure and immunoregulatory phenotype were analyzed by flow cytometry in the same patient prospectively at two time points: (i) before and (ii) 3 months after beginning of L-thyroxine treatment (hypothyroidism vs. euthyroidism, respectively). Percentage of plasmacytoid DCs in peripheral blood mononuclear cells fraction was significantly decreased in the course of L-thyroxine treatment (0.27 ± 0.19 vs. 0.11 ± 0.08; p < 0.05), whereas we did not observe any changes in the number of conventional DCs. However, the phenotypic analysis showed a significant increase of conventional DCs expressing CD86 and CD91 (64.25 ± 21.6% vs. 86.3 ± 11%; p < 0.05 and 30.75 ± 11.66% vs. 44.5 ± 13.3%; p < 0.05; respectively) in euthyroid patients. Standard L-thyroxine supplementation in HT patients exerted significant immunoregulatory effects, associated with quantitative and phenotypic changes of peripheral blood DC subpopulations.

Objectives To estimate neuropathic sign/symptom rates with initiation of combination antiretroviral therapy (cART) in HIV-infected ART-naive patients, and to investigate risk factors for: peripheral neuropathy and symptomatic peripheral neuropathy (SPN), recovery from peripheral neuropathy/SPN after neurotoxic ART (nART) discontinuation, and the absence of peripheral neuropathy/SPN while on nART. Design AIDS Clinical Trials Group (ACTG) Longitudinal Linked Randomized Trial participants who initiated cART in randomized trials for ART-naive patients were annually screened for symptoms/signs of peripheral neuropathy. ART use and disease characteristics were collected longitudinally. Methods Peripheral neuropathy was defined as at least mild loss of vibration sensation in both great toes or absent/hypoactive ankle reflexes bilaterally. SPN was defined as peripheral neuropathy and bilateral symptoms. Generalized estimating equation logistic regression was used to estimate associations. Results Two thousand, one hundred and forty-one participants were followed from January 2000 to June 2007. Rates of peripheral neuropathy/SPN at 3 years were 32.1/8.6% despite 87.1% with HIV-1RNA 400 copies/ml or less and 70.3% with CD4 greater than 350 cells/µl. Associations with higher odds of peripheral neuropathy included older patient age and current nART use. Associations with higher odds of SPN included older patient age, nART use, and history of diabetes mellitus. Associations with lower odds of recovery after nART discontinuation included older patient age. Associations with higher odds of peripheral neuropathy while on nART included older patient age and current protease inhibitor use. Associations with higher odds of SPN while on nART included older patient age, history of diabetes, taller height, and protease inhibitor use. Conclusion Signs of peripheral neuropathy remain despite virologic/immunologic control but frequently occurs without symptoms. Aging is a risk factor for

Medical tourism, where patients travel abroad intentionally to access medical treatment, is a growing trend. Some of these patients travel to undergo organ transplantation. This study aims to quantify the number of UK patients who undergo liver transplantation abroad, assessing their motivations and management. Questionnaires were sent to all seven UK liver transplant units enquiring about liver patients receiving transplant abroad. Included were questions on destination, motivation, and pre and post-transplant care. Responses were received from six of the seven transplant centres (86%). A total of 12 patients were identified as having undergone liver transplantation overseas. The top destinations were India, China and Egypt. Four units responded to questions regarding pre-transplant screening. One unit reported Hepatitis B and C screening not taking place. Four units responded to questions regarding post-transplant antimicrobial therapy. This revealed examples of patients inappropriately not receiving valganciclovir, co-trimoxazole, anti-fungal treatment and Hepatitis B immunoglobulins. UK patients are undergoing liver transplant abroad, albeit in small numbers. Pre and post-transplant management of these patients is of a lower standard than that provided to those undergoing transplantation in the UK. Information transfer between overseas and UK based transplant teams is poor. Copyright © 2016 Elsevier Ltd. All rights reserved.

Patients undergoing lobectomy are at significantly increased risk of lung injury. One-lung ventilation is the most commonly used technique to maintain ventilation and oxygenation during the operation. It is a challenge to choose an appropriate mechanical ventilation strategy to minimize the lung injury and other adverse clinical outcomes. In order to understand the available evidence, a systematic review was conducted including the following topics: (I) protective ventilation (PV); (II) mode of mechanical ventilation [e.g., volume controlled (VCV) versus pressure controlled (PCV)]; (III) use of therapeutic hypercapnia; (IV) use of alveolar recruitment (open-lung) strategy; (V) pre-and post-operative application of positive end expiratory pressure (PEEP); (VI) Inspired Oxygen concentration; (VII) Non-intubated thoracoscopic lobectomy; and (VIII) adjuvant pharmacologic options. The recommendations of class II are non-intubated thoracoscopic lobectomy may be an alternative to conventional one-lung ventilation in selected patients. The recommendations of class IIa are: (I) Therapeutic hypercapnia to maintain a partial pressure of carbon dioxide at 50–70 mmHg is reasonable for patients undergoing pulmonary lobectomy with one-lung ventilation; (II) PV with a tidal volume of 6 mL/kg and PEEP of 5 cmH2O are reasonable methods, based on current evidence; (III) alveolar recruitment [open lung ventilation (OLV)] may be beneficial in patients undergoing lobectomy with one-lung ventilation; (IV) PCV is recommended over VCV for patients undergoing lung resection; (V) pre- and post-operative CPAP can improve short-term oxygenation in patients undergoing lobectomy with one-lung ventilation; (VI) controlled mechanical ventilation with I:E ratio of 1:1 is reasonable in patients undergoing one-lung ventilation; (VII) use of lowest inspired oxygen concentration to maintain satisfactory arterial oxygen saturation is reasonable based on physiologic principles; (VIII) Adjuvant drugs

Balanced transmembrane signals maintain a competent peripheral B cell pool limited in self-reactive B cells that may produce pathogenic autoantibodies. To identify molecules regulating peripheral B cell survival and tolerance to self-antigens (Ags), a gene modifier screen was performed with B cells from CD22-deficient C57BL/6 (CD22−/−[B6]) mice that undergo activation-induced cell death (AICD) and fail to up-regulate c-Myc expression after B cell Ag receptor ligation. Likewise, lysozyme auto-Ag–specific B cells in IgTg hen egg lysozyme (HEL) transgenic mice inhabit the spleen but undergo AICD after auto-Ag encounter. This gene modifier screen identified EndoU, a single-stranded RNA-binding protein of ancient origin, as a major regulator of B cell survival in both models. EndoU gene disruption prevents AICD and normalizes c-Myc expression. These findings reveal that EndoU is a critical regulator of an unexpected and novel RNA-dependent pathway controlling peripheral B cell survival and Ag responsiveness that may contribute to peripheral B cell tolerance.

A significant proportion of cancer patients at end of life (EOL) undergo radiotherapy, but this evidence is not from nationwide population-based studies. The aims of this population-based study were to investigate the trend in undergoing radiotherapy among Taiwanese cancer patients' last month of life (EOL radiotherapy) in 2001-2010 and to identify factors associated with EOL radiotherapy. This was a population-based retrospective cohort study analyzing data from Taiwan's national death registry, cancer registry, and National Health Insurance claims for EOL radiotherapy using multilevel generalized linear mixed modeling. Participants were Taiwanese cancer patients (N = 339,546) who died in 2001-2010. Overall, 8.59% (7.97%-9.85%) of patients underwent EOL radiotherapy with a decreasing trend over time. Correlates of EOL radiotherapy included male gender, younger age, residing in less urbanized areas, diagnosis of lung cancer, metastatic disease, death within two years of diagnosis, and without comorbidities. Cancer patients were more likely to undergo EOL radiotherapy if they received primary care from medical oncologists and pediatricians, in a nonprofit, teaching hospital with a larger case volume of terminally ill cancer patients, and greater EOL care intensity. Approximately one-tenth of Taiwanese cancer patients underwent EOL radiotherapy with a decreasing trend over time. Undergoing EOL radiotherapy was associated with demographics, disease characteristics, physician specialty, and primary hospital's characteristics and EOL care practice patterns. Clinical and financial interventions should target hospitals/physicians that tend to aggressively treat at-risk cancer patients at EOL to carefully evaluate the appropriateness and effectiveness of using EOL radiotherapy.

Perioperative risk associated with pulmonary hypertension (PH) in patients undergoing non-cardiac surgery (NCS) remains poorly defined. We report perioperative outcomes in a large cohort of patients undergoing NCS, comparing those with and without PH. Patients undergoing NCS at our institution between January 2002 and December 2006, were cross matched with a Right Heart Catheterization (RHC) database for the same period. Patients were excluded if they were <18 years old and if they underwent cardiac surgery prior to NCS or minor procedures using local anesthesia or sedation. Controls were defined as patients who underwent similar NCS with mean pulmonary arterial pressure (MPAP) ≤ 25 mmHg. 173 patients underwent RHC and NCS during the specified period and were included in the analysis. Of these 96 (55%) had PH. Mean pulmonary arterial pressure (p = 0.001), American Association of Anesthesiology Class (p = 0.02), and chronic renal insufficiency (p = 0.03) were determined as independent risk factors for post-operative morbidity. Patients with PH were more likely to develop congestive heart failure (p < 0.001; OR: 11.9), hemodynamic instability (p < 0.002), sepsis (p < 0.0005), and respiratory failure (p < 0.004). Patients with PH needed longer ventilatory support (p < 0.002), stayed longer in the ICU (p < 0.04), and were more frequently readmitted to the hospital within 30 days (p < 008; OR 2.4). In addition to the traditionally known risk factors for outcomes after NCS such as coronary artery disease, diabetes mellitus, chronic renal insufficiency, American Society of Anesthesiology class, the presence of underlying PH can have a significant negative impact on perioperative outcomes.

Optimizing perioperative outcomes for older patients with rheumatoid arthritis undergoing arthroplasty: emphasis on medication management.

PubMed

Goodman, Susan M

2015-05-01

Patients with rheumatoid arthritis continue to undergo arthroplasty despite widespread use of potent disease-modifying drugs (DMARDs), including the biologic tumor necrosis-α inhibitors. In fact, over 80 % of RA patients are taking DMARDs or biologics at the time of arthroplasty. While many RA-specific factors including disease activity and disability may contribute to the increase in infection in RA patients undergoing arthroplasty, immunosuppressant medications may also play a role. As the age of patients with RA undergoing arthroplasty is rising, and the incidence of arthroplasty among the older population is increasing, optimal perioperative management of DMARDs and biologics in older patients with RA is an increasing challenge. Although evidence is sparse, most evidence supports withholding tumor necrosis-α inhibitors and other biologics prior to surgery based on the dosing interval, and continuing methotrexate and hydroxychloroquine through the perioperative period. There is no consensus regarding leflunomide, and rituximab risk does not appear related to the interval between infusion and surgery. This paper reviews arthroplasty outcomes including complications in patients with RA, and discusses the rationale for strategies for the optimal medication management of DMARDs and biologics in the perioperative period to minimize complications and improve outcomes.

Glomerular filtration rate (GFR) is partially impaired in patients with multiple sclerosis (MS). When given chemotherapy before receiving hematopoietic stem-cell transplantation, GFR might be further deteriorated. To measure the effect of cyclophosphamide on GFR in patients with MS who undergo chemotherapy. We estimated GFR based on creatinine and cystatin C plasma concentrations in patients undergoing autologous hematopoietic stem-cell transplantation to treat their MS. Baseline GFR values were lower in the 28 patients with MS than in the 20 healthy individuals. Also, according to the Chronic Kidney Disease-Epidemiology Collaborative Group (CKD-EPI) 2012 Creat-CysC equation criteria, 4 of 28 patients were classified as having chronic kidney disease (CKD) before receiving the chemotherapy drugs. After receiving 4 × 50 mg per kg body weight cyclophosphamide, abnormal GFR results were recorded in 12 of 28 patients. Renal function must be monitored in patients with MS undergoing autologous stem-cell transplantation. Also, chemotherapy should be constrained as much as possible to prevent further deterioration of renal function.

Objective To detect the frequencies of peripheral programmed death-1 + (PD-1 + ) lymphocytes and CD4 + CD25 + FOXP3 + regulatory T cells in patients with gastric adenocarcinoma. Methods The study enrolled 29 patients with gastric adenocarcinoma and 29 age- and sex-matched healthy controls. Frequencies of PD-1 + lymphocytes and CD4 + CD25 + FOXP3 + regulatory T cells were detected using flow cytometry. Results The number of PD-1 + lymphocytes and CD4 + CD25 + FOXP3 + regulatory T cells in peripheral blood was higher in patients with gastric adenocarcinoma than that in the control group. Moreover, linear correlation analysis indicated a positive correlation between PD-1 expression and frequency of CD4 + CD25 + FOXP3 + regulatory T cells in peripheral blood of the patients. Conclusion Gastric adenocarcinoma patients present with increased PD-1 + lymphocytes and CD4 + CD25 + FOXP3 + regulatory T cells in the peripheral blood.

Among the many changes caused by a surgical insult one of the least studied is postoperative immunosuppression. This phenomenon is an important cause of infectious complications of surgery such as surgical site infection or hospital acquired pneumonia. One of the mechanisms leading to postoperative immunosuppression is the apoptosis of immunological cells. Anesthesia during surgery is intended to minimize harmful changes and maintain perioperative homeostasis. The aim of the study was evaluation of the effect of the anesthetic technique used for total knee replacement on postoperative peripheral blood lymphocyte apoptosis. 34 patients undergoing primary total knee replacement were randomly assigned to two regional anesthetic protocols: spinal anesthesia and combined spinal-epidural anesthesia. 11 patients undergoing total knee replacement under general anesthesia served as control group. Before surgery, immediately after surgery, during first postoperative day and seven days after the surgery venous blood samples were taken and the immunological status of the patient was assessed with the use of flow cytometry, along with lymphocyte apoptosis using fluorescent microscopy. Peripheral blood lymphocyte apoptosis was seen immediately in the postoperative period and was accompanied by a decrease of the number of T cells and B cells. There were no significant differences in the number of apoptotic lymphocytes according to the anesthetic protocol. Changes in the number of T CD3/8 cells and the number of apoptotic lymphocytes were seen on the seventh day after surgery. Peripheral blood lymphocyte apoptosis is an early event in the postoperative period that lasts up to seven days and is not affected by the choice of the anesthetic technique.

Objectives To determine whether nonselective preoperative carotid artery ultrasound screening alters management of patients scheduled for coronary artery bypass grafting (CABG), and whether such screening affects neurologic outcomes. Methods From March 2011 to September 2013, preoperative carotid artery ultrasound screening was performed on 1236 of 1382 patients (89%) scheduled to undergo CABG. Carotid artery stenosis (CAS) was classified as none or mild (any type 0%–59% stenosis), moderate (unilateral 60%-79% stenosis), or severe (bilateral 60%-79% stenosis or unilateral 80%–100% stenosis). Results A total of 1069 (86%) hadpatients with patients with ≥moderate CAS, 1 of 19 (5.3%) undergoing CABG + CEA and 3 of 148 (2.0%) undergoing CABG alone experienced stroke (P = .4). In patients with moderate CAS, stroke occurred in 1 of 11 (9.1%) off-pump and 1 of 79 (1.3%) on-pump patients (P = .2). In patients with severe CAS, stroke occurred in 1 of 6 (17%) off-pump and 1 of 71 (1.4%) on-pump patients (P = .15). Conclusions Routine preoperative carotid artery evaluation altered the management of a minority of patients undergoing CABG; this did not translate into perioperative stroke risk. Hence, a more targeted approach for preoperative carotid artery evaluation should be adopted. PMID:26586360

The utility of routine preoperative electrocardiography (ECG) for assessing perioperative cardiovascular risk in patients undergoing noncardiac, nonvascular surgery (NCNVS) is unclear. There would be an association between preoperative ECG and perioperative cardiovascular outcomes in patients undergoing NCNVS. A total of 660 patients undergoing NCNVS were prospectively evaluated. Patients age >18 years who underwent an elective, nonday case, open surgical procedure were enrolled. Troponin I concentrations and 12-lead ECG were evaluated the day before surgery, immediately after surgery, and on the first 5 postoperative days. Preoperative ECG showing atrial fibrillation, left or right bundle branch block, left ventricular hypertrophy, frequent premature ventricular complexes, pacemaker rhythm, Q-wave, ST-segment changes, or sinus tachycardia or bradycardia were classified as abnormal. The patients were followed up during hospitalization and were evaluated for the presence of perioperative cardiovascular events (PCE). Eighty patients (12.1%) experienced PCE. Patients with abnormal ECG findings had a greater incidence of PCE than those with normal ECG results (16% vs 6.4%; P < 0.001). Mean QTc interval was significantly longer in the patients who had PCE (436.6 ± 31.4 vs 413.3 ± 16.7 ms; P < 0.001). Univariate analysis showed a significant association between preoperative atrial fibrillation, pacemaker rhythm, ST-segment changes, QTc prolongation, and in-hospital PCE. However, only QTc prolongation (odds ratio: 1.15, 95% confidence interval: 1.06-1.2, P < 0.001) was an independent predictor of PCE according to the multivariate analysis. Every 10-ms increase in QTc interval was related to a 13% increase for PCE. Prolongation of the QTc interval on the preoperative ECG was related with PCE in patients undergoing NCNVS. © 2011 Wiley Periodicals, Inc.

Peripheral catheterization is a technique that can be difficult in some patients. Some studies have recently described the use of ultrasound to guide the venous catheterization. To describe the success rate, time required, complications of ultrasound-guided peripheral venous catheterization. and patients and professionals satisfaction The search was performed in databases (Medline-PubMed, Cochrane Library, CINAHL and Cuiden Plus) for studies published about ultrasound-guided peripheral venous catheterization performed on patients that provided results on the success of the technique, complications, time used, patient satisfaction and the type of professional who performed the technique. A total of 21 studies were included. Most of them get a higher success rate 80% in the catheterization ecoguide and time it is not higher than the traditional technique. The Technical complications analyzed were arterial puncture rates and lower nerve 10%. In all studies measuring and comparing patient satisfaction in the art ecoguide is greater. Various professional groups perform the technique. The use of ultrasound for peripheral pipes has a high success rate, complications are rare and the time used is similar to that of the traditional technique. The technique of inserting catheters through ultrasound may be learned by any professional group performing venipuncture. Finally, it gets underscores the high patient satisfaction with the use of this technique. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

Forced-Air Warmers and Surgical Site Infections in Patients Undergoing Knee or Hip Arthroplasty.

PubMed

Austin, Paul N

2017-01-01

The majority of the evidence indicates preventing inadvertent perioperative hypothermia reduces the incidence of many perioperative complications. Among the results of inadvertent perioperative hypothermia are increased bleeding, myocardial events, impaired wound healing, and diminished renal function. Most researchers agree there is an increased incidence of surgical site infections in patients who experience inadvertent perioperative hypothermia. Forced-air warming is effective in preventing inadvertent perioperative hypothermia. Paradoxically, forced-air warmers have been implicated in causing surgical site infections in patients undergoing total knee or hip arthroplasty. The results of investigations suggest these devices harbor pathogens and cause unwanted airflow disturbances. However, no significant increases in bacterial counts were found when forced-air warmers were used according to the manufacturer's directions. The results of one study suggested the incidence of surgical site infections in patients undergoing total joint arthroplasty was increased when using a forced-air warmer. However these researchers did not control for other factors affecting the incidence of surgical site infections in these patients. Current evidence does not support forced-air warmers causing surgical site infections in patients undergoing total knee or hip arthroplasty. Clinicians must use and maintain these devices as per the manufacturer's directions. They may consider using alternative warming methods. Well-conducted studies are needed to help determine the role of forced-air warmers in causing infections in these patients.

BACKGROUND Recent studies suggest that the decision to undergo breast reconstruction and contralateral prophylactic mastectomy (CPM) are closely related. Here we describe the relationship between method of reconstruction and decision to undergo CPM. We also evaluate recent trends in CPM use in the context of literature questioning its oncologic benefit. STUDY DESIGN Female patients with unilateral breast cancer were identified and data extracted from the Surveillance, Epidemiology, and End Results (SEER) database from 2000 through 2010. Logistic regression analyses were performed to study the relationship between having CPM and key demographic, oncologic and reconstructive factors among women with unilateral breast cancer. RESULTS A total of 157,042 patients with unilateral breast cancer were included. CPM rate increased from 7.7% to 28.3% during the study period, and the proportion of reconstructed patients who underwent CPM increased from 19% to 46%. Reconstruction was associated with higher odds of CPM (odds ratio (OR) 2.79, 95% CI 2.70-2.88, p<0.0001) after controlling for oncologic and demographic factors. Among women who had reconstruction, implant-based reconstruction was associated with significantly higher odds of CPM than autologous tissue reconstruction (OR 1.38, p<0.0001). Over the study period Implant reconstruction rates increased from 28.2% to 43.5% while autologous reconstruction rates decreased from 32.2% to 27.3% in CPM patients. CONCLUSIONS The frequency of CPM continues to increase in spite of literature questioning its oncologic benefit. Our study confirms that reconstruction and the decision to undergo CPM are closely related, with implant reconstruction dominating in patients who undergo CPM. Given the relationship between reconstruction and the choice for CPM, plastic surgeons should play an active role in educating patients to avoid decisions made based on inaccurate information.

Our primary objective was to assess the feasibility of geriatric patients (>65 yr) bypassing the postanesthesia care unit (PACU) after ambulatory surgery. A secondary objective was to compare recovery profiles when using three different maintenance anesthetics. Ninety ASA physical status I--III consenting outpatients (>65 yr) undergoing short urologic procedures were randomly assigned to one of three anesthetic treatment groups. After a standardized induction with fentanyl and propofol, anesthesia was maintained with propofol (75-150 microg center dot kg(-1) center dot min(-1) IV), isoflurane (0.7%-1.2% end tidal), or desflurane (3%-6% end tidal), in combination with nitrous oxide 70% in oxygen. In all three groups, the primary anesthetic was titrated to maintain an electroencephalographic-bispectral index value of 60-65. Recovery times, postanesthesia recovery scores, and therapeutic interventions in the PACU were recorded. Although emergence times were similar in the three groups, the time to achieve a fast-track discharge score of 14 was significantly shorter in patients receiving desflurane compared with propofol and isoflurane (22 +/- 23 vs 33 +/- 25 and 44 +/- 36 min, respectively). On arrival in the PACU, a significantly larger percentage of patients receiving desflurane were judged to be fast-track eligible compared with those receiving either isoflurane and propofol (73% vs 43% and 44%, respectively). The number of therapeutic interventions in the PACU was also significantly larger in the Isoflurane group when compared with the Propofol and Desflurane groups (21 vs 11 and 7, respectively). In conclusion, use of desflurane for maintenance of anesthesia should facilitate PACU bypass ("fast-tracking") of geriatric patients undergoing short urologic procedures. Geriatric outpatients undergoing brief urologic procedures more rapidly achieve fast-tracking discharge criteria after desflurane (versus isoflurane and propofol) anesthesia. Use of isoflurane was also

To compare the acute procedure and angiographic outcomes of peripheral artery disease (PAD) patients treated with orbital atherectomy stratified by gender. The CONFIRM I, II, and III registries are US multicenter, nonrandomized, all-comers registries of PAD patients who were treated with orbital atherectomy. All patients with gender specified in the registry database were included in the current analysis, which compared the final residual stenosis achieved after atherectomy and the rate of acute complications in female and male patients. The 3 registries included 3131 patients with 4761 lesions: 1261 women (mean age 73.2 ± 10.7 years) with 1874 lesions and 1870 men (mean age 70.4 ± 10.2) with 2887 lesions. The women were older (p < 0.001) and had a higher but nonsignificant prevalence of critical limb ischemia (p = 0.075). After treatment, the final residual stenosis in women vs. men was 9% ± 11% vs. 11% ± 11%, respectively (p < 0.001). Women had a higher rate of all types of dissection (13.3% vs. 9.9%, p<0.001). However, both genders had similar rates of flow-limiting dissections (1.6% vs. 1.4%, p = 0.61), perforation, slow flow, vessel closure, spasm, embolism, and thrombus formation. The gender analysis of the CONFIRM registries revealed that there was successful lesion modification with orbital atherectomy in both men and women; however, women had a higher rate of dissection (all types). This difference is likely because of the older age and higher percentage of critical limb ischemia in women in this cohort. These results, however, suggest that additional studies should be completed to further understand the increased risks for women vs. men during endovascular procedures. © The Author(s) 2015.

We aimed to determine the prevalence and co-occurrence of tobacco smoking, alcohol consumption, and depressive symptoms among a sample of head and neck cancer (HNC) patients undergoing radiotherapy. A total of 307 HNC patients participated in a multi-site stepped-wedge randomized controlled trial (RCT) evaluating the effectiveness of a dietitian-delivered health behavior intervention in patients with HNC undergoing radiotherapy. During week one of radiotherapy patients completed measures of smoking, alcohol consumption, and level of depression. Approximately one-fifth (21%) of patients had two or more co-occurring problems: current smoking, hazardous alcohol use, and/or likely presence of a major depressive episode (MDE). Approximately one-third (34%) of the sample were current smokers, one-third (31%) were drinking hazardously and almost one-fifth (19%) had likely cases of depression. Comorbidity of smoking, hazardous alcohol use, and MDE is high in HNC patients, and interventions need to address this cluster of cancer risk factors. © 2018 The Authors.

PURPOSE We aimed to determine the radiation doses delivered to patients undergoing general examinations using computed or digital radiography systems in Turkey. MATERIALS AND METHODS Radiographs of 20 patients undergoing posteroanterior chest X-ray and of 20 patients undergoing anteroposterior kidney-ureter-bladder radiography were evaluated in five X-ray rooms at four local hospitals in the Ankara region. Currently, almost all radiology departments in Turkey have switched from conventional radiography systems to computed radiography or digital radiography systems. Patient dose was measured for both systems. The results were compared with published diagnostic reference levels (DRLs) from the European Union and International Atomic Energy Agency. RESULTS The average entrance surface doses (ESDs) for chest examinations exceeded established international DRLs at two of the X-ray rooms in a hospital with computed radiography. All of the other ESD measurements were approximately equal to or below the DRLs for both examinations in all of the remaining hospitals. Improper adjustment of the exposure parameters, uncalibrated automatic exposure control systems, and failure of the technologists to choose exposure parameters properly were problems we noticed during the study. CONCLUSION This study is an initial attempt at establishing local DRL values for digital radiography systems, and will provide a benchmark so that the authorities can establish reference dose levels for diagnostic radiology in Turkey.

Both diabetes mellitus and hyperglycemia per se are associated with negative outcomes after cardiac surgery. In this article, we review these associations, the possible mechanisms that lead to adverse outcomes, and the epidemiology of diabetes focusing on those patients requiring cardiac surgery. We also examine outpatient and perioperative management of diabetes with the same focus. Finally, we discuss our own efforts to improve glycemic management of patients undergoing cardiac surgery at our institution, including keys to success, results of implementation, and patient safety concerns.

Previous studies performed in non-obese patients undergoing elective surgery have revealed that psychological factors may affect postoperative analgesic requirements. The aim of this observational prospective study was to investigate the extent to which psychopathological dimensions, including anxiety, depression and alexithymia, may influence postoperative pain intensity and analgesics consumption using patient-controlled analgesia (PCA) in patients undergoing bariatric surgery. 120 patients, aged 18-60years, with an ASA physical status I-II, undergoing gastric bypass were enrolled. Anxiety and depression Hamilton scales, and Toronto Alexithymia scale, were administered to patients on the day before surgery. General anesthesia was standardized. After awakening, a PCA pump with intravenous tramadol was immediately made available for a 36-hour postoperative analgesia. Visual analog scale at rest (VASr) and after coughing (VASi), and effective PCA requests number were postoperatively recorded. Pearson's correlations, Anova analyses and multiple linear regression were used for statistical purpose. Positive correlations were found between anxiety, depression, alexithymia and all pain indicators (p<0.01). Analyses of variance showed that anxious (p<0.001), depressed (p<0.001) and alexithymic (p<0.05) patients had high pain indicators. VASr and VASi were predicted by anxiety and depression (p<0.05), but not by alexithymia; effective PCA requests number was predicted by anxiety, depression and alexithymia (p<0.001). Obese patients with high depression, anxiety and alexithymia levels rated their pain as more intense and required a larger amount of tramadol. Pain perception intensity was predicted by anxiety and depression but not by alexithymia, whereas analgesics consumption was predicted by all the investigated psychopathological dimensions.

Despite selection process before awake-craniotomy, some patients experience an unexpected decline in language functions in the operating room (OR), compared with their baseline evaluation, which may impair their functional monitoring. To investigate this phenomenon we prospectively compared language function the day before surgery and on entrance to the OR. Data were collected prospectively from consecutive patients undergoing awake-craniotomy with intraoperative cortical mapping for resection of gliomas affecting language areas. Language functions of 79 patients were evaluated and compared 1-2 days before surgery and after entering the OR. Changes in functional linguistic performance were analyzed with respect to demographic, clinical, and pathologic characteristics. There was a significant decline in language function, beyond sedation effect, after entering the OR, (from median/interquartile range: 0.94/0.72-0.98 to median/interquartile range: 0.86/0.51-0.94; Z = -7.19, P < 0.001). Univariate analyses revealed that this decline was related to age, preoperative Karnofsky Performance Scale, tumor location, tumor pathology, and preexisting language deficits. Multivariate stepwise regression identified tumor pathology and the presence of preoperative language deficit as significant independent predictors for this functional decline. Patients undergoing awake-craniotomy may experience a substantial decline in language functioning after entering the OR. Tumor grade and the presence of preoperative language deficits were significant risk factors for this phenomenon, suggesting a possible relation between cognitive reserve, psychobehavioral coping abilities and histologic features of a tumor involving language areas. Capturing and identifying this unique population of patients who are prone to experience such language decline may improve our ability in the future to select patients eligible for awake-craniotomy.

Pectus excavatum (PEx) is one of the most common congenital chest wall deformities. Depending on the severity, presentation of PEx may range from minor cosmetic issues to disabling cardiopulmonary symptoms. The effect of PEx on adult patients has not been extensively studied. Symptoms may not occur until the patient ages, and they may worsen over the years. More recent publications have implied that PEx may have significant cardiopulmonary implications and repair is of medical benefit. Adults presenting for PEx repair can undergo a successful repair with a minimally invasive “Nuss” approach. Resolution of symptoms, improved quality of life, and satisfying results are reported.

2015-04-01

Quiescent-interval single-shot MRA (QISS-MRA) is a promising nonenhanced imaging technique for assessment of peripheral arterial disease (PAD). Previous studies at 3 Tesla included only very limited numbers of patients for correlation of QISS-MRA with digital subtraction angiography (DSA) as standard of reference (SOR). The aim of this prospective institutional review board-approved study was to compare QISS-MRA at 3 Tesla with DSA in a larger patient group. Our study included 32 consecutive patients who underwent QISS-MRA, contrast-enhanced MRA (CE-MRA), and DSA. Two readers independently performed a per-segment evaluation of QISS-MRA and CE-MRA for image quality and identification of non-significant stenosis (<50%) versus significant stenosis (50-100%). The final dataset included 1,027 vessel segments. Reader 1 and 2 rated image quality as diagnostic in 96.8 and 98.0% of the vessel segments on QISS-MRA and in 99.3 and 98.4% of the vessel segments on CE-MRA, respectively. DSA was available for 922 segments and detected significant stenosis in 133 segments (14.4%). Consensus reading yielded the following diagnostic parameters for QISS-MRA versus CE-MRA: sensitivity: 83.5% (111/133) versus 82.7% (110/133), p = 0.80; specificity: 93.9% (741/789) versus 95.7% (755/789), p = 0.25; and diagnostic accuracy: 92.4% (852/922) versus 93.8% (865/922), p = 0.35. In conclusion, using DSA as SOR, QISS-MRA and CE-MRA at 3 Tesla showed similar diagnostic accuracy in the assessment of PAD. A limitation of QISS-MRA was the lower rate of assessable vessel segments compared to CE-MRA.

The aim of this study was to characterize the pharmacokinetics (PK) of propofol in ICU patients undergoing long-term sedation and to assess the influence of routinely collected covariates on the PK parameters. Propofol concentration-time profiles were collected from 29 patients. Non-linear mixed-effects modelling in NONMEM 7.2 was used to analyse the observed data. The propofol pharmacokinetics was best described with a three-compartment disposition model. Non-parametric bootstrap and a visual predictive check were used to evaluate the adequacy of the developed model to describe the observations. The typical value of the propofol clearance (1.46 l/min) approximated the hepatic blood flow. The volume of distribution at steady state was high and was equal to 955.1 l, which is consistent with other studies involving propofol in ICU patients. There was no statistically significant covariate relationship between PK parameters and opioid type, SOFA score on the day of admission, APACHE II, predicted death rate, reason for ICU admission (sepsis, trauma or surgery), gender, body weight, age, infusion duration and C-reactive protein concentration. The population PK model was developed successfully to describe the time-course of propofol concentration in ICU patients undergoing prolonged sedation. Despite a very heterogeneous group of patients, consistent PK profiles were observed. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Peripheral neuropathy in liver cirrhosis.

Neuropathy in association with chronic liver disease, including cirrhosis, is recognized; however, there are differences in the incidence and type of neuropathy reported. The causal relationship of liver disease to neuropathy has been questioned. This study was designed to evaluate the incidence and character of peripheral neuropathy in patients with liver cirrhosis. The effect of alcohol consumption, severity of liver disease and encephalopathy on the incidence and severity of neuropathy were also studied. Patients having an identifiable cause of peripheral neuropathy, except alcohol, were excluded from the study. Patients with evidence of vitamin B12 deficiency or diabetes were also excluded from the study. In this study, 33 patients with liver cirrhosis were evaluated clinically and electrophysiologically to detect any evidence of peripheral neuropathy. Nerve conduction studies were performed in the upper and lower limbs using surface electrodes. These patients also underwent a detailed clinical examination. Clinical signs of peripheral neuropathy were found in seven (21%) patients. Nerve conduction studies were abnormal in 24 (73%) patients. The pattern of involvement was predominantly of an axonal sensory motor polyneuropathy. Neuropathy was found both in patients with alcohol-related and non-alcohol-related cirrhosis. The presence of encephalopathy did not have a significant bearing on the incidence and severity of neuropathy. The neuropathy was also not significantly related to the severity of liver disease. The present study reveals that a significant number of patients with liver cirrhosis show evidence of peripheral neuropathy, which is present regardless of the etiology of cirrhosis, and is subclinical in a majority of these patients. The cause of neuropathy was probably the liver disease itself, as the incidence and severity of neuropathy in the alcohol-related cirrhosis, although higher, was not significantly different from the neuropathy in patients

Provision of preoperative information can alleviate patients' anxiety. However, the ideal method of delivering this information is unknown. Video information has been shown to reduce patients' anxiety, although little is known regarding the effect of preoperative multimedia information on anxiety in patients undergoing regional anaesthesia. We randomized 110 patients undergoing upper or lower limb surgery under regional anaesthesia into the study and control groups. The study group watched a short film (created by the authors) depicting the patient's in-hospital journey including either a spinal anaesthetic or a brachial plexus block. Patients' anxiety was assessed before and after the film and 1 h before and within 8 h after their operation, using the Spielberger state trait anxiety inventory and a visual analogue scale. There was no difference in state and trait anxiety between the two groups at enrollment. Women had higher baseline state and trait anxiety than men (P=0.02). Patients in the control group experienced an increase in state anxiety immediately before surgery (P<0.001), and patients in the film group were less anxious before operation than those in the control group (P=0.04). After operation, there was a decrease in state anxiety from baseline in both groups, but patients in the film group were less anxious than the control group (P=0.005). Preoperative multimedia information reduces the anxiety of patients undergoing surgery under regional anaesthesia. This type of information is easily delivered and can benefit many patients.

We compared data regarding diagnosis, treatment and follow-up of patients with dementia in the central and the peripheral areas of Israel. Data were collected from the medical records of 164 patients with advanced dementia, all residents of dementia special care units - 97 patients from a central nursing home and 67 patients from the peripheral areas. The data collected related to the period prior to hospitalization and included: demographic data, imaging tests, follow-up by a memory clinic and drug treatment prior to admission. Mini Mental State Examination on admission was also recorded. Patients in the peripheral areas were hospitalized while having better cognitive function, as demonstrated by the Mini Mental State Examination (p < 0.05). More patients in the central areas versus the peripheral areas were aided by an in-house worker prior to admission (p < 0.001). More patients with dementia in the central areas were followed up by a memory clinic (p < 0.001) and underwent brain imaging (p < 0.01) compared with patients with dementia living in the peripheral areas. Although not significant, patients from the central areas were more commonly treated with atypical neuroleptics for behavioral problems (p = 0.05). On the basis of the current data, we suggest that there are differences in the diagnosis, follow-up and drug treatment among patients with dementia living in the central areas versus those living in the peripheral ones. Patients in the peripheral areas are hospitalized while their cognitive abilities are relatively better than those of the patients in central areas. © The Author(s) 2013.

Video Material as an Effective Educational Tool to Address Informational and Educational Needs of Cancer Patients Undergoing Radiation Therapy.

With increasing rates of cancer patients undergoing radiation therapy, the treatment itself can cause patients significant amounts of anxiety and distress. This can be attributed to the diagnosis of the disease, lack of knowledge of what radiation therapy is, expectations and management of side effects, and the lack of knowledge of supportive care for patients and their families. Providing patients with effective educational tools to meet the informational needs of cancer patients undergoing radiation therapy can empower patients and allow them to participate in treatment decision-making and their own healthcare. This discussion paper will evaluate several studies on the psychological impact of cancer patients undergoing radiation therapy and how video material can effectively meet the informational and educational needs of this patient population group.

Gupta, Kamesh; Jain, Anand; Rohatgi, Anurag

A descriptive, observational study was completed in a tertiary care hospital between November 2014 and March 2016. Fifty consecutive patients of Type 2-Diabetes Mellitus who had been on metformin therapy for at least three months were included in our study. Several Parameters were compared with vitamin B12 levels and severity of peripheral neuropathy (using Toronto Clinical Scoring System (TCSS) and Nerve Conduction Velocity). These included the duration of diabetes, duration of metformin usage, dietary history, and HbA1c levels. Definite B12 deficiency was defined as B12<150pg/ml and possible B12 deficiency as <220pg/ml. In our study, we found a negative correlation between duration of metformin use and Vitamin B12 levels(r=-0.40). The mean Vitamin B12 levels seen in our study was 212.3pg/mL. There is a positive correlation between the duration of metformin therapy and peripheral neuropathy (r=0.40). The mean TCSS score was 6.8. The percentage of patients with mild neuropathy was 28%, with moderate neuropathy was 20% and severe neuropathy in 12% of the patients. The average duration of metformin use in patients without peripheral neuropathy was 5.5yrs whereas the average length of metformin use in patients with peripheral neuropathy was 10.4 yrs. Patients on long-term metformin therapy are at a high risk for Vitamin B12 deficiency and peripheral neuropathy. Interval Screening for peripheral neuropathy is recommended for patients on metformin even if Vitamin B12 levels appear to be normal. Copyright © 2017 Diabetes India. Published by Elsevier Ltd.

Frailty and falls among adult patients undergoing chronic hemodialysis: a prospective cohort study

PubMed Central

2013-01-01

Background Patients undergoing hemodialysis are at high risk of falls, with subsequent complications including fractures, loss of independence, hospitalization, and institutionalization. Factors associated with falls are poorly understood in this population. We hypothesized that insights derived from studies of the elderly might apply to adults of all ages undergoing hemodialysis; we focused on frailty, a phenotype of physiological decline strongly associated with falls in the elderly. Methods In this prospective, longitudinal study of 95 patients undergoing hemodialysis (1/2009-3/2010), the association of frailty with future falls was explored using adjusted Poisson regression. Frailty was classified using the criteria established by Fried et al., as a combination of five components: shrinking, weakness, exhaustion, low activity, and slowed walking speed. Results Over a median 6.7-month period of longitudinal follow-up, 28.3% of study participants (25.9% of those under 65, 29.3% of those 65 and older) experienced a fall. After adjusting for age, sex, race, comorbidity, disability, number of medications, marital status, and education, frailty independently predicted a 3.09-fold (95% CI: 1.38-6.90, P=0.006) higher number of falls. This relationship between frailty and falls did not differ for younger and older adults (P=0.57). Conclusions Frailty, a validated construct in the elderly, was a strong and independent predictor of falls in adults undergoing hemodialysis, regardless of age. Our results may aid in identifying frail hemodialysis patients who could be targeted for multidimensional fall prevention strategies. PMID:24131569

To explore the perspectives of patients undergoing haemodialysis in Singapore on an imposed dietary and fluid restriction regime. Adherence to prescribed dietary and fluid restriction constructs the fundamental basis of self-care with improved morbidity and mortality. However, most patients have struggled to adhere in this aspect. Existing studies have presented limited understanding on the facilitators and barriers of dietary and fluid adherence among haemodialysis patients. An exploratory qualitative study. A purposive sample of 14 patients undergoing haemodialysis was recruited from a renal unit of a tertiary hospital in Singapore. Data were collected through face-to-face individual interviews and subsequently analysed by thematic analysis. Four themes emerged: (1) Pessimism, (2) Existing struggles, (3) Perceived quality of support, and (4) Immensity of self-discipline. The imposed dietary and fluid restriction is a constant struggle and a cause of suffering among haemodialysis patients in Singapore. Nonetheless, they are generally submissive to their fluid restrictions for the sake of survival or to meet the expectations of their loved ones. The imposed dietary restrictions are generally neglected. The findings from this study can provide useful information in reviewing existing educational strategies, policies and nursing care. This is especially important because most patients exhibit high reliance on healthcare professionals. © 2017 John Wiley & Sons Ltd.

The prevalence, intensity, safety, and efficacy of oral anticoagulation (OAC) in addition to dual antiplatelet therapy (DAPT) in "real-world" patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) have not yet been fully evaluated. In the Coronary REvascularization Demonstrating Outcome Study in Kyoto registry cohort-2, a total of 1,057 patients with AF (8.3%) were identified among 12,716 patients undergoing first PCI. Cumulative 5-year incidence of stroke was higher in patients with AF than in no-AF patients (12.8% vs 5.8%, p <0.0001). Although most patients with AF had CHADS2 score ≥2 (75.2%), only 506 patients (47.9%) received OAC with warfarin at hospital discharge. Cumulative 5-year incidence of stroke in the OAC group was not different from that in the no-OAC group (13.8% vs 11.8%, p = 0.49). Time in therapeutic range (TTR) was only 52.6% with an international normalized ratio of 1.6 to 2.6, and only 154 of 409 patients (37.7%) with international normalized ratio data had TTR ≥65%. Cumulative 5-year incidence of stroke in patients with TTR ≥65% was markedly lower than that in patients with TTR <65% (6.9% vs 15.1%, p = 0.01). In a 4-month landmark analysis in the OAC group, there was a trend for higher cumulative incidences of stroke and major bleeding in the on-DAPT (n = 286) than in the off-DAPT (n = 173) groups (15.1% vs 6.7%, p = 0.052 and 14.7% vs 8.7%, p = 0.10, respectively). In conclusion, OAC was underused and its intensity was mostly suboptimal in real-world patients with AF undergoing PCI, which lead to inadequate stroke prevention. Long-term DAPT in patients receiving OAC did not reduce stroke incidence. Copyright © 2014 The Authors. Published by Elsevier Inc. All rights reserved.

We instituted a ketamine-predominant analgesic regimen in the peri- and postoperative periods to limit the effects of narcotic analgesia on bowel function in patients undergoing radical cystectomy. The primary end points of interest were time to return of bowel function, time to discharge, and efficacy of the analgesic regimen. We performed a retrospective chart review of patients undergoing robotic-assisted laparoscopic cystectomy (RARC) with urinary diversion by a single surgeon at our institution from January 1, 2011 to June 30, 2012. Patients receiving the opioid-minimizing ketamine protocol were compared to a cohort of patients undergoing RARC with an opioid-predominant analgesic regimen. In total, 15 patients (Group A) were included in the ketamine-predominant regimen and 25 patients (Group B) in the opioid-predominant control group. Three patients (19%) in Group A discontinued the protocol due to ketamine side effects. The mean time to bowel movement and length of stay in Group A versus Group B was 3 versus 6 days (p < 0.001), and 4 versus 8 days, respectively (p < 0.001). Group A patients received an average of 13.0 mg of morphine versus 97.5 mg in Group B (p < 0.001). Patients who received our ketamine pain control regimen had a shorter time to return of bowel function and length of hospitalization after RARC. Our study has its limitations as a retrospective, single surgeon, single institution study and the non-randomization of patients. Notwithstanding these limitations, this study was not designed to show inferiority of one approach, but instead to show that our protocol is safe and efficacious, warranting further study in a prospective fashion.

Peripheral venous catheters are frequently used in hospitalized patients but increase the risk of nosocomial bloodstream infection. Evidence-based guidelines describe specific steps that are known to reduce infection risk. However, the degree of guideline implementation in clinical practice is not known. The aim of this study was to determine the use of specific steps for insertion of peripheral venous catheters in clinical practice and to implement a multimodal intervention aimed at improving both compliance and the optimum order of the steps. The study was conducted at University Hospital Hamburg. An optimum procedure for inserting a peripheral venous catheter was defined based on three evidence-based guidelines (WHO, CDC, RKI) including five steps with 1A or 1B level of evidence: hand disinfection before patient contact, skin antisepsis of the puncture site, no palpation of treated puncture site, hand disinfection before aseptic procedure, and sterile dressing on the puncture site. A research nurse observed and recorded procedures for peripheral venous catheter insertion for healthcare workers in four different departments (endoscopy, central emergency admissions, pediatrics, and dermatology). A multimodal intervention with 5 elements was established (teaching session, dummy training, e-learning tool, tablet and poster, and direct feedback), followed by a second observation period. During the last observation week, participants evaluated the intervention. In the control period, 207 insertions were observed, and 202 in the intervention period. Compliance improved significantly for four of five steps (e.g., from 11.6% to 57.9% for hand disinfection before patient contact; p<0.001, chi-square test). Compliance with skin antisepsis of the puncture site was high before and after intervention (99.5% before and 99.0% after). Performance of specific steps in the correct order also improved (e.g., from 7.7% to 68.6% when three of five steps were done; p<0.001). The

Intrahepatic cholangiocarcinoma with hepatic hilus involvement has been either classified as intrahepatic cholangiocarcinoma or hilar cholangiocarcinoma. The present study aimed to investigate the clinicopathologic characteristics and short- and long-term outcomes after curative resection for hilar type intrahepatic cholangiocarcinoma in comparison with peripheral intrahepatic cholangiocarcinoma and hilar cholangiocarcinoma. A total of 912 patients with mass-forming peripheral intrahepatic cholangiocarcinoma, 101 patients with hilar type intrahepatic cholangiocarcinoma, and 159 patients with hilar cholangiocarcinoma undergoing curative resection from 2000 to 2015 were included from two multi-institutional databases. Clinicopathologic characteristics and short- and long-term outcomes were compared among the 3 groups. Patients with hilar type intrahepatic cholangiocarcinoma had more aggressive tumor characteristics (eg, higher frequency of vascular invasion and lymph nodes metastasis) and experienced more extensive resections in comparison with either peripheral intrahepatic cholangiocarcinoma or hilar cholangiocarcinoma patients. The odds of lymphadenectomy and R0 resection rate among patients with hilar type intrahepatic cholangiocarcinoma were comparable with hilar cholangiocarcinoma patients, but higher than peripheral intrahepatic cholangiocarcinoma patients (lymphadenectomy incidence, 85.1% vs 42.5%, P < .001; R0 rate, 75.2% vs 88.8%, P < .001). After curative surgery, patients with hilar type intrahepatic cholangiocarcinoma experienced a higher rate of technical-related complications compared with peripheral intrahepatic cholangiocarcinoma patients. Of note, hilar type intrahepatic cholangiocarcinoma was associated with worse disease-specific survival and recurrence-free survival after curative resection versus peripheral intrahepatic cholangiocarcinoma (median disease-specific survival, 26.0 vs 54.0 months, P < .001; median recurrence

This study was aimed at assessing the effectiveness and the importance of an oral hygiene (OH) protocol in patients undergoing radiation therapy and chemotherapy after prosthesis rehabilitation, in order to reduce or minimize oral complications. This study was carried out at the Department of Dental Science, at the University of Bari-Italy from December 2012 to December 2015 on 34 selected patients with primary oral cancer undergoing chemotherapy and radiotherapy after prosthesis rehabilitation. They were divided into 2 groups according to their age, sex and cancer therapy. Seventeen patients were assigned to the control group and seventeen in the experimental one. In the experimental group (Table 1), patients underwent an oral hygiene protocol whereas in the control group (Table 2) patients received the usual care provided within the clinical setting. All the patients gave written informed consent. It has been asked and obtained the authorisation from the Ethics Committee of the Dental Science and Surgery Department. Results show that in patients undergoing the oral hygiene protocol, the complications and the risks of infection and permanent dental problems have been minimized. Indeed, of the seventeen patients undergoing the OH protocol, 70% obtained positive results and were satisfied with the program outcome. The role of the health care providers is essential to educate patients to adhere to the prescribed treatments and reinforce their motivation in oral hygiene. The oral hygiene procedures prevent and ameliorate oral complications due to the radiation therapy and chemotherapy.

Liver dysfunction increases death and morbidity after cardiac operations. There are currently no data evaluating liver function in patients undergoing transcatheter aortic valve replacement (TAVR). We aimed therefore to evaluate our TAVR results in regard to liver function. A total of 640 consecutive TAVR patients were evaluated. Of those, 11 patients presented with chronic liver disease before TAVR. The Model for End-Stage Liver Disease score was used to measure liver function in these patients. The primary study end point was 30-day mortality in patients presenting with liver dysfunction. Secondary study end point was liver enzymes after TAVR. The mean Model for End-Stage Liver Disease score in patients with chronic liver disease was 16.8 ± 6.2 (median, 18; range, 7 to 26). The 30-day mortality was 9.1% (57 of 629) in patients presenting without liver disease and 9.1% (1 of 11) in patients with liver disease (p = 1.00). Patients with chronic liver disease showed significantly higher preoperative levels of γ-glutamyl transpeptidase (p < 0.001). After TAVR, we observed a significant increase in alanine aminotransferase on postoperative day 3 compared with preoperative values (p < 0.001), accompanied by a decrease in albumin (p < 0.001). Liver cirrhosis per se is not considered as a contraindication for cardiac operations. In the present study, we did not observe a higher 30-day mortality rate in liver cirrhotic patients undergoing TAVR, suggesting TAVR as a feasible alternative with acceptable outcomes in patients with chronic liver disease. Moreover, the present study is the first to evaluate liver variables in patients undergoing TAVR. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

N-acetylcysteine improves coronary and peripheral vascular function.

Andrews, N P; Prasad, A; Quyyumi, A A

We investigated whether N-acetylcysteine (NAC), a reduced thiol that modulates redox state and forms adducts of nitric oxide (NO), improves endothelium-dependent vasomotion. Coronary atherosclerosis is associated with endothelial dysfunction and reduced NO activity. In 16 patients undergoing cardiac catheterization, seven with and nine without atherosclerosis, we assessed endothelium-dependent vasodilation with acetylcholine (ACH) and endothelium-independent vasodilation with nitroglycerin (NTG) and sodium nitroprusside (SNP) before and after intracoronary NAC. In 14 patients femoral vascular responses to ACH, NTG and SNP were measured before and after NAC. Intraarterial NAC did not change resting coronary or peripheral vascular tone. N-acetylcysteine potentiated ACH-mediated coronary vasodilation; coronary blood flow was 36 +/- 11% higher (p < 0.02), and epicardial diameter changed from -1.2 +/- 2% constriction to 4.7 +/- 2% dilation after NAC (p = 0.03). Acetylcholine-mediated femoral vasodilation was similarly potentiated by NAC (p = 0.001). Augmentation of the ACH response was similar in patients with or without atherosclerosis. N-acetylcysteine did not affect NTG-mediated vasodilation in either the femoral or coronary circulations and did not alter SNP responses in the femoral circulation. In contrast, coronary vasodilation with SNP was significantly greater after NAC (p < 0.05). Thiol supplementation with NAC improves human coronary and peripheral endothelium-dependent vasodilation. Nitroglycerin responses are not enhanced, but SNP-mediated responses are potentiated only in the coronary circulation. These NO-enhancing effects of thiols reflect the importance of the redox state in the control of vascular function and may be of therapeutic benefit in treating acute and chronic manifestations of atherosclerosis.

There are few data on the risk for peripheral neuropathy associated with dronedarone, a newer antiarrhythmic medicine. The objective of this study was to assess whether dronedarone is potentially associated with an increased risk for peripheral neuropathy compared with other antiarrhythmics, including amiodarone, sotalol, flecainide, and propafenone. The MarketScan database was used for identifying patients who were at least 18 years of age, had atrial fibrillation or flutter, and had not been diagnosed with peripheral neuropathy in the 180-day period prior to or on the date of the first prescription of an antiarrhythmic between July 20, 2009, and December 31, 2011. Peripheral neuropathy that occurred during the treatment period for a study drug was ascertained using ICD-9-CM diagnostic codes. For each antiarrhythmic, the incidence rate of peripheral neuropathy was calculated. The adjusted hazard ratio (aHR) for peripheral neuropathy for dronedarone compared with another antiarrhythmic was obtained, with control for age, sex, diabetes mellitus status, and the presence of other comorbidities. The study population included 106,933 patients treated with dronedarone (n = 12,989), amiodarone (n = 45,173), sotalol (n = 22,036), flecainide (n = 14,244), or propafenone (n = 12,491). The incidence rates (per 1000 person-years) of peripheral neuropathy were 1.33 for dronedarone, 2.38 for amiodarone, 1.20 for sotalol, 1.08 for flecainide, and 1.97 for propafenone. The aHRs for peripheral neuropathy for dronedarone relative to other drugs ranged from 0.53 (95% CI, 0.21-1.34) compared with propafenone, to 0.94 (95% CI, 0.38-2.30) compared with sotalol. A new-user analysis showed similar results. The risks for peripheral neuropathy were not significantly different between dronedarone and other antiarrhythmics.

A plethora of papers have been written regarding postcatheterization femoral pseudoaneurysms. However, literature is lacking on pseudoaneurysmal management in patients undergoing coronary artery bypass grafting (CABG). Thus, we examined if pseudoaneurysms with subsequent CABG can be managed with the same strategies as those not exposed to the intense anticoagulation accompanying CABGs. During a 14-year study period, we retrospectively examined femoral iatrogenic pseudoaneurysms (IPSAs) diagnosed postheart catheterization in patients having a subsequent CABG. Patient information was obtained from electronic medical records and included pseudoaneurysm characteristics, treatment, and resolution. Outcomes of interest included the occurrence of IPSA treatment failures and complications. In the 66 patients (mean age, 66 ± 11 years, 46% male) meeting inclusion criteria, mean dose of heparin received during the CABG procedure was 34 000 ± 23 000 units. The IPSA size distribution was the following: 17% of IPSAs measured <1 cm, 55% between 1 and 3 cm, and 21% measured >3 cm. Pseudoaneurysms were managed with compression, duplex-guided thrombin injection, and surgical repair (1%, 27%, and 26% of cases, respectively). Thrombin injection and surgical repair were 100% effective at treating pseudoaneurysms, with 1 patient experiencing a surgical site infection postsurgical repair. Observation-only management was employed in 30 (45%) patients. Nine of 30 patients with no intervention beyond observation had duplex documented resolution/thrombosis during follow-up. One patient initially managed by observation required readmission and surgical repair of an enlarging pseudoaneurysm (6 cm growth) following CABG. Management of pseudoaneurysms in patients prior to CABG should be similar to those patients not undergoing intense anticoagulation. In appropriate cases, small aneurysms can be safely observed, while thrombin injections are effective and safe as well. Thus, routine open

To describe a characteristic form of the corona sign and its clinical relevance to the degree of corneal endothelial decompensation and investigate the underlying mechanism using a rabbit model. These observational cases include 31 patients undergoing penetrating keratoplasty (PKP) and 15 patients undergoing Descemet stripping automated endothelial keratoplasty (DSAEK) with special attention to the circumferentially developed corneal epithelial edema. We also conducted a laboratory observation of horizontal water flow in the rabbit cornea. We consistently observed the corona sign at the superior periphery during the initial stage of corneal endothelial decompensation after PKP. With progressive corneal endothelial cellular loss, the epithelial edema gradually expanded circumferentially in the periphery. The endothelial cellular density associated with the corona sign significantly (P < 0.01) decreased compared with that without the sign. The endothelial cellular density decreased significantly (P < 0.05) in cases with a circumferential corona sign compared with a superior corona sign. After DSAEK, however, the corneal epithelial edema subsided from the center but persisted peripherally as a corona sign in all cases. By 3 months postoperatively, the epithelial edema was confined to the superior periphery along with uneventful corneal endothelial healing. Rabbit experiments showed that total corneal endothelial decompensation decreased the horizontal intracorneal water migration (Inoue-Ohashi phenomenon) in the corneal periphery and induced peripheral corneal edema. The slit-lamp microscopic findings of the corona-like epithelial edema in the peripheral cornea are associated with the stage of corneal endothelial function. To support this, the developmental mechanism of the corona sign was demonstrated experimentally.

The study was made to evaluate the long-term physical and psychosocial changes after high-dose therapy and autologous bone marrow or peripheral stem transplantation for recurrent lymphoid malignancies. Patients who had undergone high dose therapy and autologous bone marrow or peripheral stem cell transplantation for recurrent lymphoid malignancies at least 1 year previously were contacted by phone interview regarding their status after the transplant. The patients' comments were confirmed by checking medical records when possible. Fifty patients who had undergone transplantation at the University of Nebraska Medical Center at least 1 year before the interview were available for interview and willing to answer questions. After transplant, many patients noticed temporary changes in their appearance, which usually returned to normal within 1 year. Few patients reported remarkable cardiovascular, gastrointestinal, or pulmonary changes after transplantation. However, up to one-third of the patients reported changes in sexual function or desire. The most common infectious problem after transplant was Herpes zoster, which occurred in 25% of the patients. Overall, the patients had a positive outlook after high-dose therapy and transplantation, with most being able to return to work and enjoy a normal life style. Ninety-six percent of the patients stated that they would be willing to undergo high-dose therapy and transplantation again under the same circumstances.

To evaluate the impact of CT perfusion imaging on the detection of peripheral chronic pulmonary embolisms (CPE). 62 patients underwent a dual-energy chest CT angiographic examination with (a) reconstruction of diagnostic and perfusion images; (b) enabling depiction of vascular features of peripheral CPE on diagnostic images and perfusion defects (20 segments/patient; total: 1240 segments examined). The interpretation of diagnostic images was of two types: (a) standard (i.e., based on cross-sectional images alone) or (b) detailed (i.e., based on cross-sectional images and MIPs). The segment-based analysis showed (a) 1179 segments analyzable on both imaging modalities and 61 segments rated as nonanalyzable on perfusion images; (b) the percentage of diseased segments was increased by 7.2 % when perfusion imaging was compared to the detailed reading of diagnostic images, and by 26.6 % when compared to the standard reading of images. At a patient level, the extent of peripheral CPE was higher on perfusion imaging, with a greater impact when compared to the standard reading of diagnostic images (number of patients with a greater number of diseased segments: n = 45; 72.6 % of the study population). Perfusion imaging allows recognition of a greater extent of peripheral CPE compared to diagnostic imaging. • Dual-energy computed tomography generates standard diagnostic imaging and lung perfusion analysis. • Depiction of CPE on central arteries relies on standard diagnostic imaging. • Detection of peripheral CPE is improved by perfusion imaging.

The aim of this study was to describe the imaging appearance of patients undergoing active surveillance for ductal carcinoma in situ (DCIS). We retrospectively identified 29 patients undergoing active surveillance for DCIS from 2009 to 2014. Twenty-two patients (group 1) refused surgery or were not surgical candidates. Seven patients (group 2) enrolled in a trial of letrozole and deferred surgical excision for 6-12 months. Pathology and imaging results at the initial biopsy and follow-up were recorded. In group 1, the median follow-up was 2.7 years (range: 0.6-13.9 years). Fifteen patients (68%) remained stable. Seven patients (32%) underwent additional biopsies with invasive ductal carcinoma diagnosed in two patients after 3.9 and 3.6 years who developed increasing calcifications and new masses. In group 2, one patient (14%) was upstaged to microinvasive ductal carcinoma at surgery. Among the patients in both groups with calcifications (n = 26), there was no progression to invasive disease among those with stable (50%, 13/26) or decreased (19%, 5/26) calcifications. Among a DCIS active surveillance cohort, invasive disease progression presented as increasing calcifications and a new mass following more than 3.5 years of stable imaging. In contrast, there was no progression to invasive disease among cases of DCIS with stable or decreasing calcifications. Close imaging is a key follow-up component in active surveillance.

Diabetes mellitus (DM) and metabolic syndrome are important targets for secondary prevention in cardiovascular disease. However, the prevalence in patients undergoing elective percutaneous coronary intervention is not well defined. We aimed to analyse the prevalence and characteristics of patients undergoing percutaneous coronary intervention with previously unrecognized prediabetes, diabetes and metabolic syndrome. Data were collected from 740 patients undergoing elective percutaneous coronary intervention between November 2010 and March 2013 at a tertiary referral center. Prevalence of DM and prediabetes was evaluated using Haemoglobin A1c (A1c ≥ 6.5% for DM, A1c 5.7-6.4% for prediabetes). A modified definition was used for metabolic syndrome [three or more of the following criteria: body mass index ≥30 kg/m2; triglycerides ≥ 150 mg/dL; high density lipoprotein <40 mg/dL in men and <50 mg/dL in women; systolic blood pressure ≥ 130 mmHg and/or diastolic ≥ 85 mmHg; and A1c ≥ 5.7% or on therapy]. Mean age was 67 years, median body mass index was 28.2 kg/m(2) and 39% had known DM. Of those without known DM, 8.3% and 58.5% met A1c criteria for DM and for prediabetes at time of percutaneous coronary intervention. Overall, 54.9% met criteria for metabolic syndrome (69.2% of patients with DM and 45.8% of patients without DM). Among patients undergoing elective percutaneous coronary intervention, a substantial number were identified with a new DM, prediabetes, and/or metabolic syndrome. Routine screening for an abnormal glucometabolic state at the time of revascularization may be useful for identifying patients who may benefit from additional targeting of modifiable risk factors.

Nutritional status is one of the most important issues faced by cancer patients. Several studies have shown that a low preoperative nutritional status is associated with a worse prognosis in patients with various types of cancer, including esophageal cancer (EC). Recently, neoadjuvant chemotherapy (NAC) and/or radiotherapy have been accepted as the standard treatment for resectable advanced EC. However, NAC has the potential to deteriorate the nutritional status of a patient. This study aimed to evaluate the prognostic significance of the nutritional status for EC patients who underwent NAC. We retrospectively reviewed 66 squamous cell EC patients who underwent NAC consisting of docetaxel, cisplatin, and 5-fluorouracil followed by subtotal esophagectomy at Nara Medical University Hospital between January 2009 and August 2015. To assess the patients' nutritional status, the prognostic nutritional index (PNI) before commencing NAC and prior to the operation was calculated as 10 × serum albumin (g/dl) + 0.005 × total lymphocyte count in the peripheral blood (per mm3). The cutoff value of the PNI was set at 45. A multivariable analysis was performed to identify prognostic factors for overall survival (OS) and relapse-free survival (RFS). The mean pre-NAC and preoperative PNI were 50.2 ± 5.7 and 48.1 ± 4.7, respectively (P = 0.005). The PNI decreased following NAC in 44 (66.7%) patients. Before initiating NAC, 9 (13.6%) patients had a low PNI, and 12 (18.2%) patients had a low PNI prior to the operation. The pre-NAC PNI and preoperative PNI were significantly associated with the OS (P = 0.013 and P = 0.004, respectively) and RFS (P = 0.036 and P = 0.005, respectively) rates. The multivariable analysis identified the preoperative PNI as an independent prognostic factor for poor OS and RFS, although the pre-NAC PNI was not an independent predictor. Our results suggest that the preoperative PNI is a useful marker for predicting the long-term outcomes of EC patients

The aim of the study was to examine the effect of orbital implantation on peripheral blood melatonin and sex hormone levels in pediatric patients with congenital eyeball dysplasia. A total of 28 cases of pediatric patients with congenital eyeball dysplasia diagnosed in the Second Affiliated Hospital of Xi'an Jiaotong University from June 2014 to December 2014 were selected for the study. The patients included those that received orbital implantation, and the melatonin levels in the peripheral blood in patients before and after operation was observed. In addition, the sex hormone levels and T lymphocytes, plasma reactive oxygen species (ROS) and VEGF levels, urine 8-OHdG and 8-isoPGF2α levels in patients before and after treatment were detected, followed by statistical analysis. As a result, after 3 months of orbital implantation, the sex hormone levels in peripheral blood in child patients fluctuated significantly, and differences were not statistically significant (P>0.05). The peripheral blood T lymphocytes and ROS levels were significantly lower than those before treatment, and the differences were statistically significant (P<0.05). The correlation analysis revealed that the peripheral blood melatonin levels were negatively related to ROS levels; the correlation coefficient was rs = -0.481 and P<0.05. In conclusion, orbital implantation does not have significant impact on sex hormone levels in child patients with congenital eyeball dysplasia. The hydroxyapatite orbital implantation can achieve more satisfactory curative effects, and there are fewer postoperative complications. It does not affect the appearance of the eye, and therefore, it is suitable for patients with congenital eyeball dysplasia.

Limited (wedge) resection of pulmonary lesions is frequently performed as a diagnostic/therapeutic procedure. Some lesions may be difficult to locate thoracoscopically with conversion to open thoracotomy or incomplete resection being potential limitations to this approach. Multiple methods have been described to aid video-assisted thoracoscopic surgical (VATS) wedge resection of pulmonary nodules, including hookwire localization, percutaneous tattoo, or intraoperative ultrasound. We report on our experience using electromagnetic navigation bronchoscopic dye marking of small subpleural lesions to aid VATS wedge resection. A retrospective cohort study of consecutive patients undergoing VATS wedge resection of peripheral lesions. Preoperative bronchoscopy with electromagnetic navigation was utilized to guide a 25 G needle to within/adjacent to the target lesion with injection of 1 mL of methylene blue or indigo carmine under fluoroscopic vision. Six patients underwent bronchoscopic marking of peripheral pulmonary lesions, navigation deemed successful in all patients, with no procedural complications. Surgery was performed within 24 hours of bronchoscopic marking. Pleural staining by dye was visible thoracoscopically in all 6 lesions either adjacent to or overlying the lesion. All lesions were fully excised with wedge resection. Pathologic examination confirmed accuracy of dye staining. Electromagnetic navigation bronchoscopic dye marking of peripheral lesions is feasible, without complications commonly associated with percutaneous marking procedures. Further experience is required but early findings suggest that this method may have utility in aiding minimally invasive resection of small subpleural lesions.

In total joint arthroplasty (TJA) literature, there is a paucity of large cohort studies comparing chronic kidney disease (CKD) and end-stage renal disease (ESRD) vs non-CKD/ESRD patients. Thus, the purposes of this study were (1) to identify inhospital complications and mortality in CKD/ESRD and non-CKD/ESRD patients and (2) compare inhospital complications and mortality between dialysis and renal transplantation patients undergoing TJA. We queried the Nationwide Inpatient Sample database for patients with and without diagnosis of CKD/ESRD and those with a renal transplant or on dialysis undergoing primary or revision total knee or hip arthroplasty from 2007 to 2011. Patient comorbidities were identified using the Elixhauser comorbidity index. International Classification of Diseases, Ninth Revision, codes were used to identify postoperative surgical site infections (SSIs), wound complications, deep vein thrombosis, and transfusions. Chronic kidney disease/ESRD was associated with greater risk of SSIs (odds ratio [OR], 1.4; P<.001), wound complications (OR, 1.1; P=.01), transfusions (OR, 1.6; P<.001), deep vein thrombosis (OR, 1.4; P=.03), and mortality (OR, 2.1; P<.001) than non-CKD/ESRD patients. Dialysis patients had higher rates of SSI, wound complications, transfusions, and mortality compared to renal transplant patients. Chronic kidney disease/ESRD patients had a greater risk of SSIs and wound complications compared to those without renal disease, and the risk of these complications was even greater in CKD/ESRD patients receiving dialysis. These findings emphasize the importance of counseling CKD patients about higher potential complications after TJA, and dialysis patients may be encouraged to undergo renal transplantation before TJA.

OBJECT The aim of this study was to evaluate outcome in patients undergoing surgical treatment for intradural spinal tumor using a patient-oriented, self-rated, outcome instrument and a physician-based disease-specific instrument. METHODS Prospectively collected data from 63 patients with intradural spinal tumor were analyzed in relation to scores on the multidimensional patient-rated Core Outcome Measures Index (COMI) and the physician-rated modified McCormick Scale, before and at 3 and 12 months after surgery. RESULTS There was no statistically significant difference between the scores on the modified McCormick Scale preoperatively and at the 3-month follow-up, though there was a trend for improvement (p = 0.073); however, comparisons between the scores determined preoperatively and at the 12-month follow-up, as well as 3- versus 12-month follow-ups, showed a statistically significant improvement in each case (p < 0.004). The COMI scores for axial pain, peripheral pain, and back-related function showed a significant reduction (p < 0.001) from before surgery to 3 months after surgery, and thereafter showed no further change (p > 0.05) up to 12 months postoperatively. In contrast, the overall COMI score, "worst pain," quality of life, and social disability not only showed a significant reduction from before surgery to 3 months after surgery (p < 0.001), but also a further significant reduction up to 12 months postoperatively (p < 0.001). The scores for work disability showed no significant improvement from before surgery to the 3-month follow-up (p > 0.05), but did show a significant improvement (p = 0.011) from 3 months to 12 months after surgery. At the 3- and 12-month follow-ups, 85.2% and 83.9% of patients, respectively, declared that the surgical procedure had helped/helped a lot; 95.1% and 95.2%, respectively, declared that they were satisfied/very satisfied with their care. CONCLUSIONS COMI is a feasible tool to use in the evaluation of baseline symptoms and

Cross-sectional study. To investigate the factors associated with work ability in patients undergoing surgery for cervical radiculopathy. Surgery is a common treatment of cervical radiculopathy in people of working age. However, few studies have investigated the impact on the work ability of these patients. Patients undergoing surgery for cervical radiculopathy (n = 201) were recruited from spine centers in Sweden to complete a battery of questionnaires and physical measures the day before surgery. The associations between various individual, psychological, and work-related factors and self-reported work ability were investigated by Spearman rank correlation coefficient, multivariate linear regression, and forward stepwise regression analyses. Factors that were significant (P < 0.05) in each statistical analysis were entered into the successive analysis to reveal the factors most related to work ability. Work ability was assessed using the Work Ability Index. The mean Work Ability Index score was 28 (SD, 9.0). The forward stepwise regression analysis revealed 6 factors significantly associated with work ability, which explained 62% of the variance in the Work Ability Index. Factors highly correlated with greater work ability included greater self-efficacy in performing self-cares, lower physical load on the neck at work, greater self-reported chance of being able to work in 6 months' time, greater use of active coping strategies, lower frequency of hand weakness, and higher health-related quality of life. Psychological, work-related and individual factors were significantly associated with work ability in patients undergoing surgery for cervical radiculopathy. High self-efficacy was most associated with greater work ability. Consideration of these factors by surgeons preoperatively may provide optimal return to work outcomes after surgery. 3.

The overall quality of patient care is a function of the quality of both its technical and its nontechnical components. The purpose of this study was to identify the elements of nontechnical (personal) care that are most important to patients undergoing radiation therapy for prostate cancer. We reviewed the literature and interviewed patients and health professionals to identify elements of personal care pertinent to patients undergoing radiation therapy for prostate cancer. We identified 143 individual elements relating to 10 aspects of personal care. Patients undergoing radical radiation therapy for prostate cancer completed a self-administered questionnaire in which they rated the importance of each element. The overall importance of each element was measured by the percentage of respondents who rated it as "very important." The importance of each aspect of personal care was measured by the mean importance of its elements. One hundred eight patients completed the questionnaire. The percentage of patients who rated each element "very important" ranged from 7% to 95% (mean 61%). The mean importance rating of the elements of each aspect of care varied significantly: "perceived competence of caregivers," 80%; "empathy and respectfulness of caregivers," 67%; "adequacy of information sharing," 67%; "patient centeredness," 59%; "accessibility of caregivers," 57%; "continuity of care," 51%; "privacy," 51%; "convenience," 45%; "comprehensiveness of services," 44%; and "treatment environment," 30% (P<.0001). Neither age nor education was associated with importance ratings, but the patient's health status was associated with the rating of some elements of care. Many different elements of personal care are important to patients undergoing radiation therapy for prostate cancer, but the 3 aspects of care that most believe are most important are these: the perceived competence of their caregivers, the empathy and respectfulness of their caregivers, and the adequacy of

Patients with relapsed or refractory peripheral T-cell lymphoma have a poor prognosis after conventional chemotherapy. Approved novel agents have only modest single-agent activity in most subtypes of peripheral T-cell lymphoma. Panobinostat is a potent oral pan-deacetylase inhibitor. Findings of many preclinical studies have shown synergistic antilymphoma activity when panobinostat is combined with the proteasome inhibitor bortezomib. We aimed to study the effect of panobinostat and bortezomib in patients with relapsed or refractory peripheral T-cell lymphoma. In this open-label, multicentre phase 2 trial, we recruited patients aged 21 years or older with relapsed or refractory peripheral T-cell lymphoma who had received at least one previous line of systemic therapy from five tertiary hospitals in Singapore, Malaysia, and South Korea. Patients received 20 mg oral panobinostat three times a week and 1·3 mg/m(2) intravenous bortezomib two times a week, both for 2 of 3 weeks for up to eight cycles. The primary endpoint was the proportion of patients who achieved an objective response in accordance with the International Working Group revised response criteria; analyses were by intention to treat. The study is completed and is registered with ClinicalTrials.gov, number NCT00901147. Between Nov 9, 2009, and Nov 26, 2013, we enrolled 25 patients with various histological subtypes of peripheral T-cell lymphoma. Of 23 patients assessable for responses, ten (43%, 95% CI 23-63) patients had an objective response, of which five were complete responses. Serious adverse events were reported in ten (40%) of 25 patients. Common treatment-related grade 3-4 adverse events included thrombocytopenia (17 [68%]), neutropenia (ten [40%]), diarrhoea (five [20%]), and asthenia or fatigue (two [8%]). We recorded peripheral neuropathy of any grade in ten (40%) patients. Combined proteasome and histone deacetylase inhibition is safe and feasible and shows encouraging activity for patients

Rheumatoid arthritis (RA) is an autoimmune disorder characterized by progressive joint destruction that requires aggressive treatment using appropriate disease-modifying antirheumatic drugs (DMARDs). RA patients with renal failure, however, are intolerant to most DMARDs due to the potential toxicity. In Japan, tacrolimus was approved for the treatment of RA in 2005. Based on its pharmacokinetics, tacrolimus may be administered to the patients undergoing hemodialysis. We report two cases of RA patients on hemodialysis treated effectively and safely with tacrolimus.

Severe brachial plexopathy after an ultrasound-guided single-injection nerve block for total shoulder arthroplasty in a patient with multiple sclerosis.

DESPITE the known benefits of regional anesthesia for patients undergoing joint arthroplasty, the performance of peripheral nerve blocks in patients with multiple sclerosis (MS) remains controversial. MS has traditionally been described as an isolated disease of the central nervous system, without involvement of the peripheral nerves, and peripheral nerve blockade has been suggested to be safe. However, careful review of the literature suggests that MS may also be associated with involvement of the peripheral nervous system, challenging traditional teachings. There is a paucity of evidence with regard to safety in using peripheral nerve regional anesthesia in these patients. This makes it difficult to provide adequate "informed consent" to these patients. This case report describes a patient with MS who sustained a severe brachial plexopathy after a total shoulder arthroplasty during combined general anesthesia and interscalene nerve block.

Airway injury is a potentially serious and costly adverse event of anesthesia care. The epidemiologic characteristics of airway injury have not been well documented. The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) is a multicenter, prospective, outcome-oriented database for patients undergoing major surgical procedures. Using the NSQIP data for the years 2005 to 2008, we examined the incidence of, and risk factors for, airway injury. Of the 563,190 patients studied, 1202 (0.2%) sustained airway injury. The most common airway injury was lip laceration/hematoma (61.4%), followed by tooth injury (26.1%), tongue laceration (5.7%), pharyngeal laceration (4.7%), and laryngeal laceration (2.1%). Multivariable logistic modeling revealed an increased risk of airway injury in patients with Mallampati class III (adjusted odds ratio [OR], 1.69; 99% confidence interval [CI], 1.36-2.11, relative to patients with Mallampati classes I and II) or class IV (adjusted OR, 2.6; 99% CI, 1.52-4.02), and in patients aged 80 years or older (adjusted OR, 1.50; 99% CI, 1.02-2.19, relative to patients aged 40 to 49 years). The risk of airway injury for patients undergoing major surgical procedures is approximately 1 in 500. Patients with difficult airways as indicated by Mallampati classes III and IV are at significantly increased risk of sustaining airway injury during anesthesia for major surgical procedures.

Uridine monophosphate, folic acid and vitamin B12 in patients with symptomatic peripheral entrapment neuropathies.

2016-01-01

Carpal tunnel syndrome is the most common type of peripheral entrapment neuropathy. We performed an exploratory, open-label, multicenter, observational study of 48 patients with peripheral entrapment neuropathy. Patients received a daily capsule of uridine monophosphate, folic acid + vitamin B12 for 2 months and were evaluated using the Pain DETECT questionnaire. The global score for pain decreased from 17.3 ± 5.9 at baseline to 10.3 ± 6.1 at the final evaluation (p < 0.001). Concomitant analgesic and anti-inflammatory treatment was stopped or the dose reduced in 77.4% of patients. Uridine monophosphate + folic acid + vitamin B12 reduced total pain score, intensity and characterization of pain and associated symptoms. These results should be tested in a well-designed, adequately powered randomized controlled trial.

To determine whether nonselective preoperative carotid artery ultrasound screening alters management of patients scheduled for coronary artery bypass grafting (CABG), and whether such screening affects neurologic outcomes. From March 2011 to September 2013, preoperative carotid artery ultrasound screening was performed on 1236 of 1382 patients (89%) scheduled to undergo CABG. Carotid artery stenosis (CAS) was classified as none or mild (any type 0%-59% stenosis), moderate (unilateral 60%-79% stenosis), or severe (bilateral 60%-79% stenosis or unilateral 80%-100% stenosis). A total of 1069 (86%) had patients with patients with ≥moderate CAS, 1 of 19 (5.3%) undergoing CABG + CEA and 3 of 148 (2.0%) undergoing CABG alone experienced stroke (P = .4). In patients with moderate CAS, stroke occurred in 1 of 11 (9.1%) off-pump and 1 of 79 (1.3%) on-pump patients (P = .2). In patients with severe CAS, stroke occurred in 1 of 6 (17%) off-pump and 1 of 71 (1.4%) on-pump patients (P = .15). Routine preoperative carotid artery evaluation altered the management of a minority of patients undergoing CABG; this did not translate into perioperative stroke risk. Hence, a more targeted approach for preoperative carotid artery evaluation should be adopted. Copyright © 2016 The American Association for Thoracic Surgery. Published by Elsevier Inc.

Oral anticoagulation (OAC) therapy is associated with increased periprocedural risks after cardiac implantable electronic device (CIED) implantation. Patterns of anticoagulation management involving non-vitamin K antagonist oral anticoagulants (NOACs) have not been characterized. Anticoagulation strategies and outcomes differ by anticoagulant type in patients undergoing CIED implantation. Using the nationwide Outcomes Registry for Better Informed Treatment of Atrial Fibrillation, we assessed how atrial fibrillation (AF) patients undergoing CIED implantation were cared for and their subsequent outcomes. Outcomes were compared by oral anticoagulant therapy (none, warfarin, or NOAC) as well as by anticoagulation interruption status. Among 9129 AF patients, 416 (5%) underwent CIED implantation during a median follow-up of 30 months (interquartile range, 24-36). Of these, 60 (14%) had implantation on a NOAC. Relative to warfarin therapy, those on a NOAC were younger (70.5 years [range, 65-77.5 years] vs 77 years [range, 70-82 years]), had less valvular heart disease (15.0% vs 31.3%), higher creatinine clearance (67.3 [range, 59.7-99.0] vs 65.8 [range, 50.0-91.6]), were more likely to have persistent AF (26.7% vs 22.9%), and use concomitant aspirin (51.7% vs 35.2%). OAC therapy was commonly interrupted for CIED in 64% (n = 183 of 284) of warfarin patients and 65% (n = 39 of 60) of NOAC patients. Many interrupted patients received intravenous bridging anticoagulation: 33/183 (18%) interrupted warfarin and 4/39 (10%) interrupted NOAC patients. Thirty-day periprocedure bleeding and stroke adverse events were infrequent. Management of anticoagulation among AF patients undergoing CIED implantation is highly variable, with OAC being interrupted in more than half of both warfarin- and NOAC-treated patients. Bleeding and stroke events were infrequent in both warfarin and NOAC-treated patients. © 2017 The Authors. Clinical Cardiology published by Wiley Periodicals, Inc.

Evaluate patients with breast cancer undergoing chemotherapy with respect to their epidemiologic and clinical variables as well as performance at work or at home. this was a cross-sectional study including 52 women interviewed during breast cancer chemotherapy, stratified in two groups: those who continued to work and do household tasks, and did not continue to work or do household tasks. Patients were from two public hospitals in the State of São Paulo, one in Santo Andre and the other in São Bernardo do Campo. The WPAI - GH (Work Productivity and Activity Impairment) questionnaire was used to evaluate work and household performance of professionals or housewives, respectively. Mean age of the patients was 55.7 (SD=13.8), most were Caucasian (88.5%), married (55.8%), employed (65.3%) and the majority had to stop working because of treatment (51.0%), at more advanced stage (p<0.05), fatigue and nausea (p<0.05). Mean WPAI - GH was 67.04 (|SD = 5.62) for patients who stopped working and 49.17 (SD = 6.89) for those who continued to work (Mann-Whitney U test: p = 0.04). Chemotherapy leads to a decrease in performance of a sizable fraction of women with breast cancer undergoing chemotherapy. A more advanced stage of neoplasia was positively associated with withdrawal from these activities probably due to side effects such as fatigue and nausea.

Coronary artery disease occurs frequently in patients undergoing aortic reconstruction, and it has been presumed that internal carotid artery occlusive disease is also common. This has led to the practice of screening for and repairing significant carotid lesions in asymptomatic patients prior to aortic reconstruction. The purpose of this study was to determine the true prevalence of internal carotid artery disease in these patients. The records of 240 patients who underwent duplex ultrasound screening for carotid artery disease prior to aortic reconstruction were reviewed. Surgery was performed for aortic aneurysm (AA) or aorto-iliac occlusive disease (AO). The prevalence of hyperlipidemia and coronary artery disease was similar between the two groups, but tobacco use, hypertension, and diabetes mellitus differed. Internal carotid artery stenosis > or = 50% occurred in 26.7% of the total group (64 of 240 cases). Stenosis > or = 50% was more common in the AO group (40 of 101 cases, 39.6%) than the AA group (24 of 139 cases, 17.3%, P = 0.0001). Severe disease (70% to 99%) was also more common in the AO group than the AA group (9.9% versus 3.6%, P = 0.0464). Internal carotid artery disease occurs commonly in patients undergoing aortic reconstruction, and screening is worthwhile. Significant disease is more common in patients with aorto-iliac occlusive disease than in those with aortic aneurysm, although atherosclerotic risk factors occur with varying frequency in the two groups. These findings suggest that additional factors may contribute to the higher prevalence of internal carotid artery stenosis in aorto-iliac occlusive disease.

Background: Chronic renal disease is a health problem in today’s world. In the end-stages of renal disease patients depend upon alternative therapies including dialysis for their survival. However, dialysis causes several stressors on physical, mental and social performance of patients. The present study aimed to review and compare the self-concept in patients undergoing hemodialysis and peritoneal dialysis. Materials and Methods: This was a case-control study including two groups of patients, undergoing hemodialysis and peritoneal dialysis, who referred to Al-Zahra and Ali Asghar Hospitals, which are affiliated to Isfahan University of Medical Sciences. These groups were compared to the control group. Data were collected through completing the form of demographic characteristics and a questionnaire, written by the researcher, pertaining to the self-concept which was collected by the samples. The data were analyzed by the Software SPSS version 18. Findings: ANOVA (analysis of variance) showed that statistically there was a significant difference between mean score of self-concept in the three physical (body-image), psychological, and social self aspects in the two groups of hemodialysis and peritoneal dialysis with the control group; however, Duncan’s post-hoc analysis showed no significant difference between mean score of self-concept in the three mentioned aspects in the two groups of hemodialysis and peritoneal dialysis. Furthermore, ANOVA (analysis of variance) showed that there was no significant difference between mean score of the spiritual aspect of the self-concept in the two groups of hemodialysis and peritoneal dialysis with the control group. Duncan’s post-hoc analysis also showed no significant difference in this aspect between the two groups of hemodialysis and peritoneal dialysis. Conclusions: Patients undergoing dialysis have many psychological disorders and the type of dialysis is not of much importance in this regard; therefore, adequate

Lymphoma patients undergoing therapy must cope with the side-effects of the disease itself, therapy and associated immobility. Peripheral neuropathy (PNP), loss of balance control and weakness not only diminishes patients' quality of life (QOL), it can also affect planning and the dosage of therapy. Exercise may enable patients to reverse these declines, improving their performance level and QOL. We carried out a randomized, controlled trial, assigning 61 lymphoma patients either to a control group (CG; N=31) or to a 36-week intervention (IG; N=30), consisting of sensorimotor-, endurance- and strength training twice a week. Primary end point was QOL; secondary end points included movement coordination, endurance, strength and therapy-induced side-effects. Intergroup comparison revealed improved QOL- (ΔT1-T0; P=0.03) and PNP-related deep sensitivity in the IG: 87.5% were able to reduce the symptom, compared with 0% in the CG (P<0.001). Significant differences in the change of balance control could be found between the groups, with the IG improving while the CG steadily declined (monopedal static ΔT3-T0; P=0.03; dynamic ΔT3-T0; P=0.007; perturbed mono-ΔT3-T0; P=0.009 and bipedal ΔT3-T0; P=0.006), failed attempts (monopedal static ΔT3-T0; P=0.02, dynamic ΔT3-T0; P<0.001and perturbed ΔT3-T0; P=0.006) and improved time to regain balance (ΔT3-T0; P=0.04). Moreover, the change in the aerobic performance level (ΔT3-T0; P=0.05) and additional amount of exercise carried out per week [metabolic equivalent (MET); P=0.02] differed significantly across groups. Exercise, especially sensorimotor training, is a feasible and promising method to support cancer patients during therapy. It improves patients QOL, reduces restrictions from side-effects such as PNP and improves patients' balance control, physical performance level and mobility. DRKS00003894.

The present study was conducted to investigate whether upper-extremity vascular access (VA) creation increases the risk for major adverse cardiac events (MACE) and death in patients undergoing coronary artery bypass grafting (CABG) with an in situ left internal thoracic artery (ITA) graft. A total of 111 patients with CABG with a left ITA graft who underwent upper-extremity VA creation were analyzed retrospectively; 93 patients received left VA creation (83.8%, ipsilateral group) and 18 patients received right VA creation (16.2%, contralateral group). The primary outcome was the occurrence of MACE, and the secondary outcome was the composite of MACE or late death. There were no significant differences in the incidence of primary (P = 0.30) or secondary (P = 0.09) outcomes between the two groups. Multivariate regression analysis indicated that prior cerebrovascular accidents (hazard ratio [HR] 3.30; 95% confidence interval [CI] 1.37-7.97; P = 0.01) and type of VA (HR 3.44; 95% CI 1.34-8.82; P = 0.01) were independently associated with MACE; prior peripheral arterial occlusive disease (HR 4.22; 95% CI 1.62-10.98; P<0.01) and type of VA (arteriovenous fistula vs. prosthetic arteriovenous grafting) (HR 3.06; 95% CI, 1.42-6.61; P<0.01) were associated with the composite of MACE or death. The side and location of VA were not associated with MACE or death. Our study showed no definite evidence that ipsilateral VA creation affects the subsequent occurrence of MACE or late death from any cause. The type of VA (a prosthetic arteriovenous grafting) is a significant predictor of the subsequent occurrence of MACE or late death.

To determine the prevalence, location, mechanism, and characteristics of peripheral nerve injury (PNI) in trauma patients. A retrospective study of medical records with PNI diagnosis secondary to trauma in the period of 2008-2012. The following information was collected: gender, age, occupation, anatomic location, affected nerve, mechanism of injury, degree of injury, costs, and hospitalization time. The prevalence of PNI is 1.12%. The location of the nerve injury was 61% upper limb, the highest incidence was presented to the brachial plexus (35%) and ulnar nerve (18%). The mechanism of the lesion was sharp injury (19%). The PNI are commonly present in people of a productive age. Neurotmesis was the most frequent degree of lesion. The patients stayed at hospital 2.51 ± 1.29 days and the average cost was 12,474.00 Mexican pesos ± 5,595.69 (US$ 1,007.54 ± 452.21) for one nerve injury.

Peripheral nerve blocks in patients with Ehlers-Danlos syndrome, hypermobility type: a report of 2 cases.

PubMed

Ehlers-Danlos syndrome is an inherited disorder of collagen production that results in multiorgan dysfunction. Patients with hypermobility type display skin hyperextensibility and joint laxity, which can result in chronic joint instability, dislocation, peripheral neuropathy, and severe musculoskeletal pain. A bleeding diathesis can be found in all subtypes of varying severity despite a normal coagulation profile. There have also been reports of resistance to local anesthetics in these patients. Several sources advise against the use of regional anesthesia in these patients citing the 2 previous features. There have been reports of successful neuraxial anesthesia, but few concerning peripheral nerve blocks, none of which describe nerves of the lower extremity. This report describes 2 cases of successful peripheral regional anesthesia in the lower extremity. In case 1, a 16-year-old adolescent girl with hypermobility type presented for osteochondral grafting of tibiotalar joint lesions. She underwent a popliteal sciatic (with continuous catheter) and femoral nerve block under ultrasound guidance. She proceeded to surgery and tolerated the procedure under regional block and intravenous sedation. She did not require any analgesics for the following 15 hours. In case 2, an 18-year-old woman with hypermobility type presented for medial patellofemoral ligament reconstruction for chronic patella instability. She underwent a saphenous nerve block above the knee with analgesia in the distribution of the saphenous nerve lasting for approximately 18 hours. There were no complications in either case. Prohibitions against peripheral nerve blocks in patients with Ehlers-Danlos syndrome, hypermobility type, appear unwarranted. Published by Elsevier Inc.

Data on the quality of communication during informed consent for surgery is sparse; we investigated this issue in a cohort of patients undergoing laparoscopic cholecystectomy (LC). Two hundred and seven consecutive patients with benign biliary disease who had undergone LC completed 2 questionnaires. We investigated the patient choice to undergo the surgical procedure along with perceptions of risk complications presented by the surgeon. Nineteen attending surgeons also completed a questionnaire giving information on their recall perception on the information they provided. Multiple logistic regression analyses determined the predictors of perceived communication factors during the informed consent process. One hundred eighty-one patients (87.4%) returned questionnaires. Younger patients (<50 y) with lower education perceived higher level of risk complications compared with older and higher educated patients (P=0.04 and P<0.001). Younger patients felt psychologic support was necessary (P<0.001) and that quality of life issues related to the interventions were under addressed (P=0.018). Differences were observed between patients' recalled risk of complications and the risk to convert LC to open laparotomy and physicians' perception of information provided to patients regarding these aspects (P<0.01). Although informed consent for surgical procedures requires that the procedures are explained and that the patient understands the procedures and risks, our data suggest different perceptions of the quality of information provided during this process between patients and physicians. Physicians should be aware that surgical risks might be perceived differently by patients and this perception might be influenced, for example, by patients' age and education. Major efforts should be directed to improve communications skills in surgical laparoscopy.

Delirium is a common complication among elderly patients undergoing total joint arthroplasty (TJA). Its incidence has been reported from 4% to 53%. The Centers for Medicare and Medicaid Services consider delirium following TJA a "never-event." The purpose of this study is to evaluate a simple perioperative protocol used to identify delirium risk patients and prevent its incidence following TJA. Our group developed a protocol to identify and prevent delirium in patients undergoing TJA. All patients were screened and scored in the preoperative assessment, on criteria such as age, history of forgetfulness, history of agitation or visual hallucinations, history of falls, history of postoperative confusion, and inability to perform higher brain functions. Patients were scored on performance in a simple mental examination. The patients were classified as low, medium, or high risk. Patients who were identified as high risk were enrolled in a delirium avoidance protocol that minimized narcotics and emphasized nursing involvement and fluids administration. Five of 7659 (0.065%) consecutive TJA patients from 2010 to 2015 developed delirium. A total of 422 patients were identified as high risk. All 5 patients who suffered delirium were within the high risk group. No low or medium risk patients suffered a delirium complication. Three (0.039%) patients suffered drug-induced delirium, 1 (0.013%) had delirium related to alcohol withdrawal, and 1 (0.013%) had delirium after a systemic infection. This protocol is effective in identifying patients at high delirium risk and diminishing the incidence of this complication by utilizing a simple screening tool and perioperative protocol.

Aspirin has cyclooxygenase-2 (COX2)-mediated anti-inflammatory and anti-coagulant properties that may confer a positive effect in preventing and limiting the progression of prostate cancer. Prostate cancer has been shown to have poor treatment outcomes due to therapeutic resistance; therefore, COX2 inhibition caused by aspirin could represent an opportunity to augment current therapies. This is particularly of interest to patients undergoing radiation therapy (RT) where inflammation is a common side-effect. This review discusses the evidence for the potential role of aspirin in the management of patients with prostate cancer undergoing RT.

Five cases underwent successful endovascular stenting of infected aneurysms of the subclavian, femoral, and carotid arteries. All these patients were at high risk for open surgery. Covered stents were placed by percutaneous approach under local anesthesia in all patients. Postoperatively, antibiotics were continued for 3 months. A literature review using the Medline database was also undertaken, and all the relevant papers on endovascular management of peripheral infected aneurysms were takenmore » into account. Stent deployment was successful in all patients. One patient died of mediastinal sepsis and another from type A aortic dissection 5 weeks later. Two patients required drainage of the infected hematoma. Three patients did well at a median follow-up of 1 year, with no evidence of sepsis. A review of the literature shows promising early and midterm results. Most early reports were of single cases, reflecting the low incidence of peripheral infected aneurysms. We conclude that further development of endoluminal techniques and long-term follow-up to establish the durability of stenting could potentially lead to a decrease in the high morbidity and mortality rates associated with infected aneurysmal disease in this high-risk group of patients.« less

Preformed donor-specific human leukocyte antigen antibodies (DSAs) in patients undergoing simultaneous liver and kidney transplantation (SLKT) are an independent risk factor for poorer patient and renal allograft survival. The outcomes of patients highly sensitized (HS) against HLA antigens undergoing SLKT and select HS SLKT recipients undergoing desensitization at a high-volume desensitization center were investigated. Seventy-five patients undergoing SLKT at a high-volume desensitization center between January 1, 2001, and December 31, 2015, were retrospectively reviewed. HS patients were defined by panel-reactive antibody (PRA) >30% (n = 17 patients), 11 of whom received pre- or perioperative desensitization with high-dose intravenous immunoglobulin (IVIG) ± rituximab. HS patients had significantly higher class I and class II PRA (class I = 41.3% ± 40.0% vs 2.5% ± 6.3%; class II = 45.7% ± 36.4% vs 1.0% ± 2.9%; P < .001), were more likely to be female (P = .05), and more likely to have had a prior transplant (P = .03). HS patients demonstrated greater susceptibility to renal cell-mediated rejection (CMR) (23.5% vs 5.2%, P = .02) compared to nonsensitized patients. Higher renal antibody-mediated rejection (ABMR) was also observed in HS patients, 11.8% vs 3.4%, but did not reach significance (P = .18). Desensitization in select HS SLKT patients was well tolerated but did not improve patient and allograft survival or significantly curtail rejection. HS SLKT recipients demonstrated increased allograft rejection, particularly CMR, but patient and graft survival were not impacted in the first year post-transplant. Select HS SLKT patients tolerated desensitization with high-dose IVIG ± rituximab and may have received additional immunoprotection against ABMR but survival was not affected.

Interventional procedures on peripheral vessels are the field of a novel specialty dedicated to the diagnosis and minimally invasive endovascular treatment of diseases involving the cerebral, thoracic and abdominal arteries (including renal and visceral arteries), as well as the peripheral arteries (femoro-popliteal arteries and the arteries below the knee). At present, physicians with three different types of medical training, each involving particular strengths and characteristics, specialize in endovascular treatment of patients with peripheral arterial disease: vascular surgeons, interventional radiologists and interventional cardiologists. Treatment of high-risk patients in terms of anatomical and clinical (serious comorbidities) complexity raised the need for the interventional cardiologist to face issues related to technical aspects of the procedure, multilevel pathology management and adequate indication. To achieve this goal, interventional cardiologists require particular facilities and clinical skills. The objectives of this position paper from the Italian Society of Interventional Cardiology (SICI-GISE) are (i) to define the theoretical background and practical training required to ensure that interventional cardiologists maintain high-quality standards also in the field of treatment of peripheral arterial disease, by establishing shared rules and drafting papers; (ii) to standardize the procedures of interventional cardiology operational units that treat patients with peripheral arterial disease in Italy on the basis of scientific evidence, and (iii) to establish common requirements in terms of facilities and regulations.

Direct injury to the right coronary artery as a result of reparative operation on the tricuspid valve is a rare, probably underdiagnosed, but serious complication, which often involves dramatic clinical consequences. So far, only five cases have been described in the literature. We describe our single-center experience of this complication, and review and analyze relevant clinical and anatomic considerations related to this entity. Cases previously reported in the literature were also reviewed. We describe four cases of direct injury to the right coronary artery in patients undergoing tricuspid annuloplasty (DeVega annuloplasty, 3; ring annuloplasty, 1) in our institution since 2005. All patients had right ventricular dilatation and severely dilated tricuspid annulus. Right coronary artery occlusion always occurred between the right marginal artery and the crux of the heart. Patients presented with hemodynamic or electrical instability. Coronary flow could be restored in 2 patients (percutaneously 1; surgically 1), both of whom finally survived, while it was not technically possible in the other 2 (1 died). Occlusion of the right coronary artery in patients undergoing tricuspid annuloplasty is a rare complication that may occur if great annulus dilatation is present, thus altering both normal annular geometry and the relationship between the right coronary artery and the tricuspid annulus, particularly when DeVega annuloplasty is performed. Such an entity should be considered in the immediate postoperative period in an unstable patient, especially when complementary tests support this diagnosis. Prompt recognition and treatment can positively affect the patient's outcome, most often by means of an emergency revascularization strategy. Copyright © 2014 The Society of Thoracic Surgeons.

To assess the value of SYNTAX score to predict major adverse cardiac and cerebrovascular events (MACCE) among patients with three-vessel or left-main coronary artery disease undergoing percutaneous coronary intervention. 190 patients with three-vessel or left-main coronary artery disease undergoing percutaneous coronary intervention (PCI) with Cypher select drug-eluting stent were enrolled. SYNTAX score and clinical SYNTAX score were retrospectively calculated. Our clinical Endpoint focused on MACCE, a composite of death, nonfatal myocardial infarction (MI), stroke and repeat revascularization. The value of SYNTAX score and clinical SYNTAX score to predict MACCE were studied respectively. 29 patients were observed to suffer from MACCE, accounting 18.5% of the overall 190 patients. MACCE rates of low (≤ 20.5), intermediate (21.0 - 31.0), and high (≥ 31.5) tertiles according to SYNTAX score were 9.1%, 16.2% and 30.9% respectively. Both univariate and multivariate analysis showed that SYNTAX score was the independent predictor of MACCE. MACCE rates of low (≤ 19.5), intermediate (19.6 - 29.1), and high (≥ 29.2) tertiles according to clinical SYNTAX score were 14.9%, 9.8% and 30.6% respectively. Both univariate and multivariate analysis showed that clinical SYNTAX score was the independent predictor of MACCE. ROC analysis showed both SYNTAX score (AUC = 0.667, P = 0.004) and clinical SYNTAX score (AUC = 0.636, P = 0.020) had predictive value of MACCE. Clinical SYNTAX score failed to show better predictive ability than the SYNTAX score. Both SYNTAX score and clinical SYNTAX score could be independent risk predictors for MACCE among patients with three-vessel or left-main coronary artery disease undergoing percutaneous coronary intervention. Clinical SYNTAX score failed to show better predictive ability than the SYNTAX score in this group of patients.

This study aims to conduct a meta-analysis to identify and compare the effectiveness of compressive cryotherapy and cryotherapy alone for patients undergoing knee surgery. Postoperative management is an important guarantee for the success of surgery. Cryotherapy and compression are two common nursing techniques after knee surgery, and are considered to be effective for postoperative clinical symptoms such as local pain and swelling. However, no previous meta-analyses have compared the effectiveness of compressive cryotherapy and cryotherapy alone in patients undergoing knee surgery. A meta-analysis of randomized controlled trials (RCTs). We conducted a search in MEDLINE (via Pubmed, 1990-2014), EMBASE (via Elsevier, 1990-2014), Cochrane Central Register of Controlled Trials (The Cochrane Library, 1990-2014), CINAHL (1990-2014) and China National Knowledge Infrastructure (1990-2014) databases for RCTs published in English and Chinese. The primary outcome measure of interest was visual analog scale and girth measure. Finally, a meta-analysis was carried out using RevMan 5.3. Among the 593 RCTs, 10 RCTs were selected and included into this study. These studies included 522 patients who underwent knee surgery. Patients who underwent compressive cryotherapy tended to have less pain than patients who underwent cryotherapy alone at POD2 and POD3, while compressive cryotherapy had a strong tendency towards less swelling over cryotherapy alone at POD1 and POD2. However, there was no significant difference between compressive cryotherapy and cryotherapy alone at the intermediate stage of rehabilitation after knee surgery. All adverse reactions were recorded in all included RCTs. Current evidence suggests that compressive cryotherapy is beneficial to patients undergoing knee surgery at the early rehabilitation stage. At the last stage, the effectiveness of compressive cryotherapy and cryotherapy alone were found to be similar.

Estimating radiation dose to organs of patients undergoing conventional and novel multidetector CT exams using Monte Carlo simulations

NASA Astrophysics Data System (ADS)

Angel, Erin

Advances in Computed Tomography (CT) technology have led to an increase in the modality's diagnostic capabilities and therefore its utilization, which has in turn led to an increase in radiation exposure to the patient population. As a result, CT imaging currently constitutes approximately half of the collective exposure to ionizing radiation from medical procedures. In order to understand the radiation risk, it is necessary to estimate the radiation doses absorbed by patients undergoing CT imaging. The most widely accepted risk models are based on radiosensitive organ dose as opposed to whole body dose. In this research, radiosensitive organ dose was estimated using Monte Carlo based simulations incorporating detailed multidetector CT (MDCT) scanner models, specific scan protocols, and using patient models based on accurate patient anatomy and representing a range of patient sizes. Organ dose estimates were estimated for clinical MDCT exam protocols which pose a specific concern for radiosensitive organs or regions. These dose estimates include estimation of fetal dose for pregnant patients undergoing abdomen pelvis CT exams or undergoing exams to diagnose pulmonary embolism and venous thromboembolism. Breast and lung dose were estimated for patients undergoing coronary CTA imaging, conventional fixed tube current chest CT, and conventional tube current modulated (TCM) chest CT exams. The correlation of organ dose with patient size was quantified for pregnant patients undergoing abdomen/pelvis exams and for all breast and lung dose estimates presented. Novel dose reduction techniques were developed that incorporate organ location and are specifically designed to reduce close to radiosensitive organs during CT acquisition. A generalizable model was created for simulating conventional and novel attenuation-based TCM algorithms which can be used in simulations estimating organ dose for any patient model. The generalizable model is a significant contribution of this

Background Syphilis, a sexually transmitted disease caused by spirochetal bacterium Treponema pallidum, can progress to affect the central nervous system, causing neurosyphilis. Accumulating evidence suggest that regulatory T cells (Tregs) may play an important role in the pathogenesis of syphilis. However, little is known about Treg response in neurosyphilis. Methodology/Principal Findings We analyzed Treg frequencies and Transforming Growth Factor-β (TGF-β) levels in the blood and CSF of 431 syphilis patients without neurological involvement, 100 neurosyphilis patients and 100 healthy donors. Suppressive function of Tregs in peripheral blood was also assessed. Among syphilis patients without neurological involvement, we found that secondary and serofast patients had increased Treg percentages, suppressive function and TGF-β levels in peripheral blood compared to healthy donors. Serum Rapid Plasma Reagin (RPR) titers were positively correlated with Treg numbers in these patients. Compared to these syphilis patients without neurological involvement, neurosyphilis patients had higher Treg frequency in peripheral blood. In the central nervous system, neurosyphilis patients had higher numbers of leukocytes in CSF compared to syphilis patients without neurological involvement. CD4+ T cells were the predominant cell type in the inflammatory infiltrates in CSF of neurosyphilis patients. Interestingly, among these neurosyphilis patients, a significant decrease in CSF CD4+ CD25high Treg percentage and number was observed in symptomatic neurosyphilis patients compared to those of asymptomatic neurosyphilis patients, which may be associated with low CSF TGF-β levels. Conclusions Our findings suggest that Tregs might play an important role in both bacterial persistence and neurologic compromise in the pathogenesis of syphilis. PMID:24244772

To determine whether the Tinnitus Handicap Inventory (THI), a validated patient-based outcomes measure, may improve our ability to quantify impact and assess therapy for patients with tinnitus. Nonrandomized, prospective analysis of 32 patients undergoing tinnitus retraining therapy (TRT). Assessment tools included comprehensive audiology, a subjective self-assessment survey of tinnitus characteristics, and the THI. Tinnitus Handicap Inventory scores were assessed at baseline and 6 months following TRT. Baseline analysis revealed significant correlation between the subjective presence of hyperacusis and higher total, emotional, and catastrophic THI scores. Tinnitus Handicap Inventory scores correlated with subjective perception of overall tinnitus effect (P<.001). Mean pure-tone threshold average was 17.4 dB, and mean speech discrimination was 97.0%. There were no consistent correlations between baseline audiologic parameters and THI scores. Following 6 months of TRT, the total, emotional, functional, and catastrophic THI scores significantly improved (P<.001). Loudness discomfort levels also significantly improved (P< or =.02). There is significant improvement in self-perceived disability following TRT as measured by the THI. The results confirm the utility of the THI as a patient-based outcomes measure for quantifying treatment status in patients with primary tinnitus.

Despite major advances in pain management, cancer pain is managed poorly in 80% of the patients with cancer. Due to deleterious side effects of pharmacology therapy in these people, there is an urgent need for clinical trials of non-pharmacological interventions. To examine the effect of therapeutic touch (TT) on the pain and fatigue of the cancer patients undergoing chemotherapy, a randomized and three-groups experimental study-experimental (TT), placebo (placebo TT), and control (usual care)-was carried out. Ninety patients undergoing chemotherapy, exhibiting pain and fatigue of cancer, were randomized into one of the three groups in the Cancer Center of Imam Khomeini Hospital in Tehran, Iran. Pain and fatigue were measured and recorded by participants before and after the intervention for 5 days (once a day). The intervention consisted of 30 min TT given once a day for 5 days between 10:00 a.m. and 10:30 a.m. The Visual Analogue Scale (VAS) of pain and the Rhoten Fatigue Scale (RFS) were completed for 5 days before and after the intervention by the subjects. The TT (significant) was more effective in decreasing pain and fatigue of the cancer patients undergoing chemotherapy than the usual care group, while the placebo group indicated a decreasing trend in pain and fatigue scores compared with the usual care group.

Purpose To develop a system prognostic of outcome in those undergoing allogeneic hematopoietic cell transplantation (allo HCT) for myelodysplastic syndrome (MDS). Patients and Methods We examined 2,133 patients with MDS undergoing HLA-matched (n = 1,728) or -mismatched (n = 405) allo HCT from 2000 to 2012. We used a Cox multivariable model to identify factors prognostic of mortality in a training subset (n = 1,151) of the HLA-matched cohort. A weighted score using these factors was assigned to the remaining patients undergoing HLA-matched allo HCT (validation cohort; n = 577) as well as to patients undergoing HLA-mismatched allo HCT. Results Blood blasts greater than 3% (hazard ratio [HR], 1.41; 95% CI, 1.08 to 1.85), platelets 50 × 109/L or less at transplantation (HR, 1.37; 95% CI, 1.18 to 1.61), Karnofsky performance status less than 90% (HR, 1.25; 95% CI, 1.06 to 1.28), comprehensive cytogenetic risk score of poor or very poor (HR, 1.43; 95% CI, 1.14 to 1.80), and age 30 to 49 years (HR, 1.60; 95% CI, 1.09 to 2.35) were associated with increased hazard of death and assigned 1 point in the scoring system. Monosomal karyotype (HR, 2.01; 95% CI, 1.65 to 2.45) and age 50 years or older (HR, 1.93; 95% CI, 1.36 to 2.83) were assigned 2 points. The 3-year overall survival after transplantation in patients with low (0 to 1 points), intermediate (2 to 3), high (4 to 5) and very high (≥ 6) scores was 71% (95% CI, 58% to 85%), 49% (95% CI, 42% to 56%), 41% (95% CI, 31% to 51%), and 25% (95% CI, 4% to 46%), respectively (P < .001). Increasing score was predictive of increased relapse (P < .001) and treatment-related mortality (P < .001) in the HLA-matched set and relapse (P < .001) in the HLA-mismatched cohort. Conclusion The proposed system is prognostic of outcome in patients undergoing HLA-matched and -mismatched allo HCT for MDS. PMID:27044940

Patients undergoing PCI early after fibrinolytic therapy are at high risk for both thrombotic and bleeding complications. We sought to assess the pharmacodynamic effects of ticagrelor versus clopidogrel in the fibrinolytic-treated STEMI patients undergoing early PCI. Patients undergoing PCI within 24 hours of tenecteplase (TNK), aspirin, and clopidogrel for STEMI were randomized to receive additional clopidogrel 300 mg followed by 75 mg daily or ticagrelor 180 mg followed by 90 mg twice daily. The platelet reactivity units (PRU) were measured with the VerifyNow Assay before study drug administration (baseline) at 4 and 24 hours post-PCI. The primary end point was PRU ≤208 at 4 hours. A total of 140 patients (74 in ticagrelor and 66 in clopidogrel group) were enrolled. The mean PRU values at baseline were similar for the 2 groups (257.8±52.9 vs 259.5±56.7, P=.85, respectively). Post-PCI, patients on ticagrelor, compared to those on clopidogrel, had significantly lower PRU at 4 hours (78.7±88 vs 193.6±86.5, respectively, P<.001) and at 24 hours (34.5±35.0 and 153.5±75.5, respectively, P<.001). The primary end point was observed in 87.8% (n=65) in the ticagrelor-treated patients compared to 57.6% (n=38) of clopidogrel-treated patients, P<.001. Fibrinolysis-treated STEMI patients who received clopidogrel and aspirin at the time of fibrinolysis and were undergoing early PCI frequently had PRU >208. In this high-risk population, ticagrelor provides more prompt and potent platelet inhibition compared with clopidogrel (Funded by Astra Zeneca; NCT01930591, https://clinicaltrials.gov/ct2/show/NCT01930591).
