    Purpose: To investigate the incidence and clinical significance of platelet responsiveness in patients receiving clopidogrel after peripheral angioplasty procedures. Materials and Methods: This prospective study included patients receiving antiplatelet therapy with clopidogrel 75 mg after infrainguinal angioplasty or stenting and who presented to our department during routine follow-up. Clopidogrel responsiveness was tested using the VerifyNow P2Y12 Assay. Patients with residual platelet reactivity units (PRU) {>=} 235 were considered as nonresponders (NR group NR), whereas patients with PRU < 235 were considered as normal (responders [group R]). Primary end points were incidence of resistance to clopidogrel and target limb reintervention (TLR)-free survival, whereas secondary end points included limb salvage rates and the identification of any independent predictors influencing clinical outcomes. Results: In total, 113 consecutive patients (mean age 69 {+-} 8 years) with 139 limbs were enrolled. After clopidogrel responsiveness analysis, 61 patients (53.9 %) with 73 limbs (52.5 %) were assigned to group R and 52 patients (46.1 %) with 66 limbs (47.5 %) to group NR. Mean follow-up interval was 27.7 {+-} 22.9 months (range 3-95). Diabetes mellitus, critical limb ischemia, and renal disease were associated with clopidogrel resistance (Fisher's exact test; p < 0.05). According to Kaplan-Meier analysis, TLR-free survival was significantly superior in group R compared with group NR (20.7 vs. 1.9 %, respectively, at 7-year follow-up; p = 0.001), whereas resistance to clopidogrel was identified as the only independent predictor of decreased TLR-free survival (hazard rate 0.536, 95 % confidence interval 0.31-0.90; p = 0.01). Cumulative TLR rate was significantly increased in group NR compared with group R (71.2 % [52 of 73] vs. 31.8 % [21 of 66], respectively; p < 0.001). Limb salvage was similar in both groups. Conclusion: Clopidogrel resistance was related with

    Peripheral artery disease (PAD) is an important marker for the risk stratification of patients with coronary artery disease (CAD). We investigated the prevalence of PAD in patients undergoing percutaneous coronary intervention (PCI) with CAD and the relationship between ankle-brachial pressure index (ABPI) and CAD severity. A total of 711 patients undergoing PCI for CAD from August 2009 to August 2011 were enrolled. PAD diagnosis was made using the ABPI. The prevalence of PAD was 12.8%. In PAD patients, mean values of right and left ABPI were 0.71 ± 0.15 and 0.73 ± 0.15. Patients with PAD had a higher prevalence of left main coronary disease (14.3% vs 5.8%, P = 0.003), more frequently had multivessel lesions (74.9% vs 52.1%, P < 0.001) and had higher SYNTAX score (18.2 ± 12.3 vs 13.1 ± 8.26, P = 0.002). Using multivariate analysis, we determined that left main CAD (OR, 2.954; 95% CI, 1.418-6.152, P = 0.004) and multivessel CAD (OR, 2.321; 95% CI, 1.363-3.953, P = 0.002) were both independently associated with PAD. We recommend that ABPI-based PAD screening should be implemented in all patients undergoing PCI with CAD, especially in severe cases. PMID:23341717

    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.

    Background Rapid growth of the elderly peritoneal dialysis (PD) population is posing a special challenge for renal teams. Peripheral artery disease (PAD) has been reported to be an independent predictor of cardiovascular and all-cause mortality in hemodialysis patients. However, the prevalence and associated risk factors for PAD in elderly PD patients have not yet been fully investigated. Methods A total of 69 elderly PD patients were included in the present study. PAD was defined as either an ankle-brachial index < 0.9 or a history of intermittent claudication, lower-limb amputation, foot ulcers, or gangrene. On enrollment, clinical and biochemical characteristics were collected. Results The overall prevalence of PAD was 31.9%. Compared with non-PAD patients, PAD patients were significantly older and more likely to be female and have longer PD duration and lower diastolic blood pressure (P < 0.001, = 0.002, 0.018, and 0.007, respectively). Serum albumin level (P < 0.001) and residual renal Kt/V value (P < 0.001) were significantly lower, but the serum C-reactive protein level (P = 0.005) was significantly higher, in PAD patients compared with non-PAD patients. Logistic regression analysis showed that serum albumin level (odds ratio = 1.485, P = 0.040) and residual renal Kt/V value (odds ratio = 1.725, P = 0.016) were independently associated with PAD. Conclusion A high prevalence of PAD appeared among elderly PD patients in Macao. Serum albumin level and residual renal Kt/V value were independently related to PAD. PMID:23112578

    Suspected deep or systemic mycosis in patients undergoing high-dose therapy and autologous or allogeneic bone marrow transplantation (BMT) requires an immediate systemic antimycotic therapy. Intravenous therapy with the standard drug conventional amphotericin-B is associated with severe adverse effects like nephrotoxicity and chills. Furthermore, BMT patients often receive other potential nephrotoxic drugs such as CsA or virustatics. In this study, we report 74 BMT-patients treated with liposomal amphotericin-B for culture-documented aspergillosis (n = 5) or candidiasis (n = 6), or for serologically (n = 35) or clinically suspected mycosis or as prophylaxis (n = 2). Therapy was initiated with a median dose of 2.8 (0.64-5.09) mg/kg body-weight and continued for 13 (1-55) days. The drug was excellently tolerated and only in one was therapy stopped due to severe chills and fever. Severe organ impairment was not observed under therapy with liposomal amphotericin-B. Creatinine decreased in five patients after an increase under preceding therapy with the conventional formulation. Influence of liposomal amphotericin-B on bilirubin and transaminases was difficult to evaluate due to therapy-related toxicity, veno-occlusive disease (VOD), and graft-versus-host disease (GvHD). 10/11 culture-positive patients died from aspergillosis (5/5) or candidiasis (5/6), but in 9/11 of these subjects the immunity was additionally compromised by GvHD, steroid therapy, and VOD. Liposomal amphotericin-B was effective in preventing relapse of systemic mycosis in 10/12 patients with a history of aspergillosis (n = 11) or candidiasis (n = 1). We conclude, that favourable toxicity of liposomal amphotericin-B should encourage dose escalation studies of liposomal amphotericin-B randomised against the conventional formulation and that the comparison of patients undergoing BMT with patients under standard chemotherapy might be difficult because of additional risk factors of the BMT-patients.

    O6-alkylguanine-DNA-alkyltransferase (ATase) levels were measured in extracts of peripheral blood lymphocytes taken at various times during chemotherapy from 19 patients with various haematological malignancies. Seven patients with advanced Hodgkin's disease received preparative treatment consisting of cyclophosphamide (1.5 g m-2, daily) administered on days 1 to 4 and BCNU (600 mg m-2) on day 5 prior to autologous bone marrow rescue (ABMR) delivered on day 7. Treatment in the remaining 12 patients consisted of cyclophosphamide (1.8 g m-2, daily) given on days 1 and 2 followed at day 4 with total body irradiation (TBI) administered in six fractions over the subsequent 3 days to a total dose of 1200 cGy prior to bone marrow transplantation. In the Hodgkin's group, significant decreases in ATase activity were seen during the cyclophosphamide treatment, and the median ATase nadir was 32% (range 0% to 57%) of pretreatment levels following 4 days of cyclophosphamide. In one patient, no ATase activity was detectable following the 4th cyclophosphamide treatment. ATase activities decreased further after BCNU administration to a median of 19% (range 0% to 32%) of pretreatment levels. Extensive cyclophosphamide-induced reduction of lymphocyte ATase levels was also seen in the other group of 12 patients treated with cyclophosphamide/TBI: postcyclophosphamide median ATase nadir was 35% (range 12% to 78%) of the pretreatment levels. No ATase depletion was seen when cyclophosphamide (up to 10 mM) was incubated for 2 h with pure recombinant human ATase in vitro whereas ATase activity was reduced by 90% on preincubation with 100 microns acrolein or with greater than 1 mM phosphoramide mustard. This suggests that a cyclophosphamide-induced decrease in ATase levels in human peripheral lymphocytes in vivo may be due to depletion mediated by the production of intracellular acrolein. Since ATase appears to be a principal mechanism in cellular resistance to the cytotoxic effects of BCNU

    This study aimed to determine the optimal fraction scheme (FS) in patients with small peripheral non-small cell lung cancer (NSCLC) undergoing stereotactic body radiotherapy (SBRT) with the 4 × 12 Gy scheme as the reference. CT simulation data for sixteen patients diagnosed with primary NSCLC or metastatic tumor with a single peripheral lesion ≤3 cm were used in this study. Volumetric modulated arc therapy (VMAT) plans were designed based on ten different FS of 1 × 25 Gy, 1 × 30 Gy, 1 × 34 Gy, 3 × 15 Gy, 3 × 18 Gy, 3 × 20 Gy, 4 × 12 Gy, 5 × 12 Gy, 6 × 10 Gy and 10 × 7 Gy. Five different radiobiological models were employed to predict the tumor control probability (TCP) value. Three other models were utilized to estimate the normal tissue complication probability (NTCP) value to the lung and the modified equivalent uniform dose (mEUD) value to the chest wall (CW). The 1 × 30 Gy regimen is recommended to achieve 4.2% higher TCP and slightly higher NTCP and mEUD values to the lung and CW compared with the 4 × 12 Gy schedule, respectively. This regimen also greatly shortens the treatment duration. However, the 3 × 15 Gy schedule is suggested in patients where the lung-to-tumor volume ratio is small or where the tumor is adjacent to the CW. PMID:26657569

    Chronic kidney disease (CKD) patients exhibit high levels of genetic damage. Part of this genetic damage is supposed to be caused by the hemodialysis (HD) therapy. Different and more efficient HD procedures could reduce the genetic damage and improve health status of CKD patients. In the present study, we analyzed if changing to online hemodiafiltration (OL-HDF) has a beneficial effect on the levels of genetic damage. The levels of genetic damage (DNA breaks and oxidatively damaged DNA) were analyzed in peripheral blood lymphocytes by using the comet assay. Forty-nine patients submitted to HD, 34 of them changing to OL-HDF and 15 patients continuing in low-flux HD, were included in the study. Plasma antioxidant capacity was also determined. Second sampling period was established after 6 months on the new or traditional HD protocol. A slight decrease in the levels of DNA damage was observed in patients who switched to OL-HDF (P=0.048) in relation to the reference group. This reduction is indicative that OL-HDF shows greater efficiency than low-flux HD in the reduction of basal levels of genetic damage. PMID:27637480

    A 19-year-old woman complaining of fever and a sore throat was diagnosed with very severe aplastic anemia (AA) by bone marrow examination at a local hospital. Despite administration of antibiotics and granulocyte-colony stimulating factor to treat the soft tissue infection in her neck, her neutrophil count showed no increase. Because emergent allogeneic stem cell transplantation (SCT) was necessary, she was referred to our hospital. On admission, computed tomography revealed right-sided severe pharyngitis and lymphadenitis causing tracheal stenosis, and emergent intubation was required the next day. Granulocyte transfusion therapy (GTX) from related donors coupled with broad-spectrum antibiotic administration controlled the otherwise overwhelming infection. The patient received allogeneic peripheral blood SCT using a reduced-intensity conditioning regimen. After allogeneic SCT, successful engraftment was obtained. She was discharged from the hospital 59 days after allogeneic SCT. She remains alive and well, as of the latest follow up. This case clearly demonstrates that GTX is useful for controlling severe infection and enables patients with severe AA to receive allogeneic SCT safely. PMID:27169447

    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.

  12. Central and peripheral pulmonary vascular resistance: Implications for who should undergo pulmonary thromboendarterectomy.

    PubMed

    Poullis, Mike

    2015-08-01

    Pulmonary thromboendarterectomy remains a technically challenging procedure with variable outcomes with regard to improvement in pulmonary function. Reducing the resistance to flow between the pulmonary valve and the pulmonary capillary bed is the key aim of surgery. The resistance to flow is due to the combination of resistance due to the central clot and distal capillary resistance. We hypothesise that the use of fluid mechanics in combination with modern radiology and electronic circuit theory can potentially predict who should or should not undergo a thromboendarterectomy. Electronic circuit theory of two resistors in series was utilised to demonstrate the concept of a model of a central clot and the peripheral pulmonary capillary bed. A simplified 2D model of the lungs utilising finite element analysis and Poiseuille's law was constructed for proof of principle. Modelling predicts that cardiac output and anatomical obstruction interplay and can have profound effects on the outcomes after thromboendarterectomy. Identical pulmonary artery pressures, due to differing cardiac outputs and identical anatomical obstructions due to thrombus can have very different physiological outcomes with regard to changes in pulmonary artery pressure. Modelling the pulmonary vasculature to determine central and peripheral pulmonary vascular resistance may help in predicting who should undergo pulmonary thromboendarterectomy. Mathematical modelling can potentially predict which patients have haemodynamically significant clots in their pulmonary arteries that thromboendarterectomy may potentially help in the setting of pulmonary capillary disease.

    To evaluate the effect of furosemide on cardiovascular hemodynamics in patients with end-stage renal failure, we studied ten patients undergoing hemodialysis three times a week. Arterial pressure, heart rate, and cardiac output (indocyanine green dye) were measured in triplicate; total peripheral resistance and central blood volume were calculated by standard formulas. Hemodynamics were determined at baseline and 5, 10, 15, and 30 minutes after intravenous (IV) bolus injection of furosemide 60 mg. Furosemide produced a decrease in central blood volume of -13% +/- 2.2% from pretreatment values (P less than .01) that was most pronounced five minutes after injection, together with a fall in cardiac output (from 6.76 +/- 0.59 to 6.17 +/- 0.52 L/min, P less than .10). Stroke volume decreased with a maximum fall occurring after 15 minutes (from 84 +/- 7 to 79 +/- 7 mL/min, P less than .05), and total peripheral resistance increased (from 15.8 +/- 2.1 to 17.8 +/- 2.3 units, P less than .05) after furosemide. Arterial pressure and heart rate did not change. The decrease in central blood volume reflects a shift of the total blood volume from the cardiopulmonary circulation to the periphery, suggesting dilation of the peripheral venous bed. Thus, even in patients undergoing hemodialysis, furosemide acutely decreases left ventricular preload by venous dilation and should therefore prove to be beneficial in acute volume overload.

    Oral mucositis is an important side effect of hematopoietic stem cell transplantation (HCST), mainly due to toxicity of conditioning regimens. It produces significant pain and morbidity. The present study reports a prospective, randomized, non-blinded study testing the efficacy of a new mouthwash, called Baxidil Onco® (Sanitas Farmaceutici Srl, Tortona, Italy) in 60 hematologic patients undergoing HCST (28 autologous, 32 allogeneic). Baxidil Onco®, used three times a day from Day -1 to Day +30, in addition to standard prophylactic schedules, was administered to 14 patients undergoing autologous and 14 patients undergoing allogeneic HCST. The remaining 32 patients (14 autologous and 18 HCST) were treated only with standard prophylactic schedules and served as control. In our study, the overall incidence of oral mucositis, measured according to the World Health Organization 0-4 scale, was 50% in the Baxidl Onco® group versus 82% in the control group (P=0.022). In addition, a significant reduction in scale 2-4 oral mucositis was observed in the Baxidil Onco® group (25% vs 56.2%; P=0.0029). The results obtained indicate that incidence, severity and duration of oral mucositis induced by conditioning regimens for HCST can be significantly reduced by oral rinsing with Baxidil Onco®, in addition to the standard prophylaxis scheme. Since Camelia Sinensin extract, which is used to produce green tea, is the main agent in this mouthwash, we hypothesize that the anti-oxidative properties of polyphenolic compounds of tea might exert protective effects on oral mucosa.

    Liver transplantation (LT) is a major surgery performed on patients with end stage liver disease. Nutrition is an integral part of patient care, and protein-energy malnutrition is almost universally present in patients suffering from liver disease undergoing LT. Nutrition assessment of preliver transplant phase helps to make a good nutrition care plan for the patients. Nutrition status has been associated with various factors which are related to the success of liver transplant such as morbidity, mortality, and length of hospital stay. To assess the nutritional status of preliver transplant patients, combinations of nutrition assessment methods should be used like subjective global assessment, Anthropometry mid arm-muscle circumference, Bioelectrical impedance analysis (BIA) and handgrip strength.

    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

Care delivered by a multidisciplinary approach is timely and streamlines the allocation of resources to provide prompt care and to attain favorable outcomes. A hospital dentist, oral and maxillofacial surgeon, and a maxillofacial prosthodontist must be involved early to prevent avoidable oral complications. Prevention and thorough preparation are vital before the start of chemotherapy and radiation therapy. Oral complications must be addressed immediately and, even with the best management, can cause delays and interruption in treatment, with serious consequences for the outcome and prognosis.

    ABSTRACT Background: Intestinal malrotation is a rare congenital anomaly. In adults is very difficult to recognize due to the lack of symptoms. Diagnosis is usually incidental during surgical procedures or at autopsy. Aim: To review the occurrence and recognition of uneventful intestinal malrotation discovered during regular cases of bariatric surgeries. Methods: Were retrospectively reviewed the medical registry of 20,000 cases undergoing bariatric surgery, from January 2002 to January 2016, looking for the occurrence of intestinal malrotation and consequences in the intraoperative technique and immediate evolution of the patients. Results: Five cases (0,025%) of intestinal malrotation were found. All of them were males, aging 45, 49, 37,52 and 39 years; BMI 35, 42, 49, 47 and 52 kg/m2, all of them with a past medical history of morbid obesity. The patient with BMI 35 kg/m2 suffered from type 2 diabetes also. All procedures were completed by laparoscopic approach, with no conversions. In one patient was not possible to move the jejunum to the upper abdomen in order to establish the gastrojejunostomy and a sleeve gastrectomy was performed. In another patient was not possible to fully recognize the anatomy due to bowel adhesions and a single anastomosis gastric bypass was preferred. No leaks or bleeding were identified. There were no perioperative complications. All patients were discharged 72 h after the procedure and no immediate 30-day complications were reported. Conclusion: Patients with malrotation can successfully undergo laparoscopic bariatric surgery. May be necessary changes in the surgical original strategy regarding the malrotation. Surgeons must check full abdominal anatomical condition prior to start the division of the stomach. PMID:27683770

    Improving clinical outcomes among high risk Class III β thalassemia major patients (Class IIIHR) receiving an allogeneic SCT remains a challenge. From October, 2009 a treosulfan based regimen (TreoFluT) was used for all consecutive Class III patients (n = 50). The clinical outcomes were compared with the historical conventional busulfan (BuCy) based regimen (n = 139). Use of TreoFluT was associated with a significantly reduced incidence of sinusoidal obstruction syndrome (SOS) among Class IIIHR cases (78% to 30%; P = 0.000) and early TRM (46% to 13%; p = 0.005). There was also a trend towards better engraftment in the Class IIIHR subset (P = 0.055). However, the use of bone marrow (BM) as source of stem cells along with the TreoFluT regimen was associated with 50% early mixed chimerism which reduced to 8.5% with the use of a peripheral blood stem cell graft (PBSC). Use of a PBSC graft was not associated with a significant increase in the incidence of acute or chronic graft versus host disease (GVHD). The overall and event free survival was significantly better among the Class IIIHR subset with the use of TreoFluT Vs. BuCy (86.6 ± 7.3 Vs. 39.4 ± 6.8%; P = 0.002 and 77.8 ± 8.8 Vs. 32.4 ± 6.5%; P = 0.003 respectively). A TreoFluT conditioning regimen with a PBSC graft can significantly improve clinical outcomes of Class IIIHR patients.

    Kidney failure affects different aspects of normal life. Among different manifestations, sleep problem can be considered as a common complaint of ESRD (End Stage Renal Disease) patients. In this study, we aimed to investigate the interrelationship between sleep disorders in ESRD patients and their characteristics. Through a cross-sectional study (2010-2011), 88 ESRD patients undergoing maintenance hemodialysis thrice weekly were recruited to enter the study. We used a self-administered questionnaire into which the data were reflected. The patients selected their specific sleep disorders using a nine-item scale while the Epworth Sleepiness Scale (ESS) determined both the presence and severity of sleep disorders. The data was finally analyzed with their baseline characteristics, dialysis characteristics, medication/stimulants use, and clinical and biochemical parameters. Over 95% of the patients had, at least, one specific sleep disorder while the ESS revealed 36.36% of patients as normal, 59.09% as having mild sleep disorders, and 4.54% as having moderate to severe sleep disorders. Sleep disorders were significantly correlated with older ages (P=0.035), dialysis dose (P=0.001), blood creatinine levels (P=0.037), upper airways obstruction (P=0.035), hepatomegaly (P=0.006), hepatic failure (P=0.001), higher blood TSH levels (P=0.039), history of hypothyroidism (P=0.005), and the use of levodopa (P=0.004), anti-hypertensive medications (P=0.006), benzodiazepines (P=0.006), Eprex (Erythropoietin) (P=0.001), Venofer (Iron Sucrose Injection) (P=0.013), and phosphate-binders agents (P=0.018). Sleep disorders are common findings among ESRD patients and seem to be a more complicated issue than a simple accumulation of the wastes products in the body. Whatever the causes of sleep disorders are, disorder-specific treatments should be considered. PMID:27107522

    Introduction Despite successful preservation of low-frequency hearing in patients undergoing cochlear implantation (CI) with shorter electrode lengths, there is still controversy regarding which electrodes maximize hearing preservation (HP). The thin straight electrode array (TSEA) has been suggested as a full cochlear coverage option for HP. However, very little is known regarding its HP potential. Methods A retrospective review was performed at two tertiary academic medical centers, reviewing the electronic records for 52 patients (mean, 58.2 yr; range, 11–85 yr) implanted with the Cochlear Nucleus CI422 Slim Straight (Centennial, CO, USA) electrode array, referred to herein as the thin straight electrode array or TSEA. All patients had a preoperative low-frequency pure-tone average (LFPTA) of 85 dB HL or less. Hearing thresholds were measured at initial activation (t1) and 6 months after activation (t2). HP was assessed by evaluating functional HP using a cutoff level of 85 dB HL PTA. Results At t1, 54% of the subjects had functional hearing; 33% of these subjects had an LFPTA between 71 and 85 dB HL, and 17% had an LFPTA between 56 and 70 dB HL. At t2, 47% of the patients had functional hearing, with 31% having an LFPTA between 71 and 85 dB HL. Discussion Preliminary research suggests that the TSEA has the potential to preserve functional hearing in 54% of patients at t1. However, 22% (n = 6) of the patients who had functional hearing at t1 (n = 28) lost their hearing between t1 and t2. Further studies are needed to evaluate factors that influence HP with the TSEA electrode and determine the speech perception benefits using electric and acoustic hearing over electric alone.

    A case is reported from the Safety Reporting System in Anaesthesia and Resuscitation database. The event occurred in a patient undergoing abdominal surgery in whom an epidural catheter was inserted for analgesia. After the intervention, the patient was transferred to the recovery unit where the patient controlled analgesia (PCA) is programmed. Due to an error, the PCA was connected to a peripheral venous line, which was detected early without harm to the patient. Communication and analysis of this incident served to introduce a new drug delivery protocol through PCA pumps, including the obligation to prescribe the PCA in the electronic system, a dual computerised check immediately before connecting PCA, labelling the medication bag as well as the proximal and distal lines, standardisation of daily visits to patients, and monthly monitoring of results.

    Objective To determine the risk factors related to the development of stroke in patients undergoing cardiac surgery. Methods A historical cohort study. We included 4626 patients aged > 18 years who underwent coronary artery bypass surgery, heart valve replacement surgery alone or heart valve surgery combined with coronary artery bypass grafting between January 1996 and December 2011. The relationship between risk predictors and stroke was assessed by logistic regression model with a significance level of 0.05. Results The incidence of stroke was 3% in the overall sample. After logistic regression, the following risk predictors for stroke were found: age 50-65 years (OR=2.11 - 95% CI 1.05-4.23 - P=0.036) and age >66 years (OR=3.22 - 95% CI 1.6-6.47 - P=0.001), urgent and emergency surgery (OR=2.03 - 95% CI 1.20-3.45 - P=0.008), aortic valve disease (OR=2.32 - 95% CI 1.18-4.56 - P=0.014), history of atrial fibrillation (OR=1.88 - 95% CI 1.05-3.34 - P=0.032), peripheral artery disease (OR=1.81 - 95% CI 1.13-2.92 - P=0.014), history of cerebrovascular disease (OR=3.42 - 95% CI 2.19-5.35 - P<0.001) and cardiopulmonary bypass time > 110 minutes (OR=1.71 - 95% CI 1.16-2.53 - P=0.007). Mortality was 31.9% in the stroke group and 8.5% in the control group (OR=5.06 - 95% CI 3.5-7.33 - P<0.001). Conclusion The study identified the following risk predictors for stroke after cardiac surgery: age, urgent and emergency surgery, aortic valve disease, history of atrial fibrillation, peripheral artery disease, history of cerebrovascular disease and cardiopulmonary bypass time > 110 minutes.

    Patients with peripheral vascular disease (PVD) often have coronary artery disease (CAD) which means an increased risk during anesthesia. The prevalence of CAD is nearly 50% among such patients. Owing to claudication, diagnostic stress tests can rarely be performed in PVD patients. In order to evaluate the frequency of transient perioperative myocardial ischemia, Holter monitoring was performed in 30 consecutive PVD patients with ASA II-III and AVK scale (Fontaine) II-IV who were undergoing femoropopliteal bypass surgery. Patients who had left bundle branch block and left ventricular hypertrophy or were taking digitalis medication were excluded from Holter monitoring. The ST-segment analysis of the frequency modulated recordings (n = 19) revealed episodes of myocardial ischemia in 26% of the patients. Most (75%) of the episodes occurred preoperatively, and 25%, during or after the anesthesia or during preparation for it. Risk factors for CAD were more often found in patients with ST segment alterations than in patients without ST segment deviations, even though the preoperative antianginal medication administered was comparable in the two subgroups. It is concluded that in a considerable subset of PVD patients silent myocardial ischemia occurs, which can be related to the different perioperative intervals by means of ST segment analyses of Holter recordings. The ST segment may allow a better insight into the cardiac state of PVD patients. Further studies are necessary in larger populations to test our suspicion.

    Patient-education information provided to patients undergoing progenitor cell transplantation (PCT) is complex. Patients' and caregivers' inability to process this information and apply principles of self-care can result in poor outcomes. An interdisciplinary team developed a three-part modular teaching program and documentation tool to address the complex informational needs of patients undergoing PCT. The modules were designed to reflect information relative to the three phases of PCT: pretransplantation, transplantation, and post-transplantation. The structured content of the documentation tool allows for consistent documentation that systematically reflects the content of the patient-education modules.

    Peripheral joint involvement is a common, potentially debilitating feature of psoriatic arthritis (PsA). Joint involvement is commonly symmetrical and polyarticular similar to rheumatoid arthritis (RA) but it can also be oligoarticular, asymmetrical or occasionally monoarticular. Involvement of the distal interphalangeal joints is a feature which distinguishes PsA from RA. Articular involvement in PsA can be severe with a mutilating arthropathy found in about 5%. These patients are characterised clinically by digital shortening and on radiographs by erosion on both sides of the joint and/or osteolysis. Treatments targeting joint disease frequently reduces symptoms and signs resulting in prevention of damage progression.

    Candidates for epilepsy surgery often use the word "hope" to express their attitudes and beliefs about surgery. However, studies suggest that hope has a multiplicity of meanings that are not well understood. The goal of this analysis was to evaluate whether Candidates for epilepsy surgery use hope language to express a traditional, expected optimism during presurgery interviews. We examined patients' uses of the word "hope" and its derivatives (hoping, hopeful, hopefully) through a secondary analysis of 37 interviews of adult patients prior to epilepsy surgery. Approximately 1/3 of all hope statements were coded as expressions of optimism, while 1/3 were not optimistic, and 1/3 had unclear meanings. In addition to traditionally optimistic uses of the term, other themes surrounding use of this word included ideas of dread, worry, uncertainty, and temporizing language. This information may help clinicians communicate more effectively with patients, enhancing the informed consent process for epilepsy surgery.

    The Prevention of Orthopaedic Implant Infection in Patients Undergoing Dental Procedures evidence-based clinical practice guideline was codeveloped by the American Academy of Orthopaedic Surgeons (AAOS) and the American Dental Association. This guideline replaces the previous AAOS Information Statement, "Antibiotic Prophylaxis in Bacteremia in Patients With Joint Replacement," published in 2009. Based on the best current evidence and a systematic review of published studies, three recommendations have been created to guide clinical practice in the prevention of orthopaedic implant infections in patients undergoing dental procedures. The first recommendation is graded as Limited; this recommendation proposes that the practitioner consider changing the long-standing practice of routinely prescribing prophylactic antibiotic for patients with orthopaedic implants who undergo dental procedures. The second, graded as Inconclusive, addresses the use of oral topical antimicrobials in the prevention of periprosthetic joint infections. The third recommendation, a Consensus statement, addresses the maintenance of good oral hygiene.

    Plasma beta-endorphin levels were studied in the coronary sinus of 8 patients undergoing percutaneous transluminal coronary angioplasty (PTCA). All the patients had ECG ischemic signs and pain during the inflation of the balloon. No significant changes in plasma beta-endorphin levels were observed during PTCA-induced ischemia. Baseline coronary sinus plasma beta-endorphin levels were found to be elevated when compared with peripheral ones which would suggest an accumulation of beta-endorphin in the ischemic heart.

    Fibromyalgia syndrome (FS) frequently co-occurs with regional pain disorders. This study evaluated how these disorders contribute to FS, by assessing effects of local active vs placebo treatment of muscle/joint pain sources on FS symptoms. Female patients with (1) FS+myofascial pain syndromes from trigger points (n=68), or (2) FS+joint pain (n=56) underwent evaluation of myofascial/joint symptoms [number/intensity of pain episodes, pressure pain thresholds at trigger/joint site, paracetamol consumption] and FS symptoms [pain intensity, pressure pain thresholds at tender points, pressure and electrical pain thresholds in skin, subcutis and muscle in a non-painful site]. Patients of both protocols were randomly assigned to two groups [34 each for (1); 28 each for (2)] to receive active or placebo local TrP or joint treatment [injection/hydroelectrophoresis] on days 1 and 4. Evaluations were repeated on days 4 and 8. After therapy, in active--but not placebo-treated-- groups: number and intensity of myofascial/joint episodes and paracetamol consumption decreased and pressure thresholds at trigger/joint increased (p<0.001); FS pain intensity decreased and all thresholds increased progressively in tender points and the non-painful site (p<0.0001). At day 8, all placebo-treated patients requested active local therapy (days 8 and 11) vs only three patients under active treatment. At a 3-week follow-up, FS pain was still lower than basis in patients not undergoing further therapy and had decreased in those undergoing active therapy from day 8 (p<0.0001). Localized muscle/joint pains impact significantly on FS, probably through increased central sensitization by the peripheral input; their systematic identification and treatment are recommended in fibromyalgia.

    Patients undergoing partial hepatectomy have an increased susceptibility to infection. To investigate whether this increased risk is related to impaired leukocyte function, we studied polymorphonuclear leukocyte (PMN) phagocytosis in patients undergoing a hemihepatectomy because of liver metastasis (LM, n = 11) and in patients undergoing major abdominal surgery because of abdominal malignancy (AM, n = 8). Eight healthy volunteers (HVs) served as controls. Leukocyte suspensions were incubated with fluorescein isothiocyanate-labeled Staphylococcus aureus, and phagocytosis was measured by flow cytometry. Preoperative PMN phagocytosis, in the presence of autologous plasma, was significantly less in patients with LM compared with patients with AM or HVs. This impaired phagocytosis was potentially restored in the presence of normal plasma. The decreased phagocytic capacity of PMNs from patients with LM was not related to levels of known plasma opsonins or phenotypic changes of PMNs. Rather, it was related to a deficiency of unidentified plasma factors. After surgery, the phagocytic capacity of PMNs of patients with AM decreased by approximately 30%, which correlated with decreasing levels of immunoglobulin G and C3. In conclusion, patients with LM had a decreased PMN phagocytic capacity before surgery. This impairment in phagocytosis disappeared 1 week after surgery. We propose that the presence of LM leads to a deficiency of factor(s) in the blood that impairs PMN phagocytic capacity.

    Transcatheter aortic valve implantation (TAVI) has extended the treatment options for severe, symptomatic aortic valve stenosis (AS). Risk factors for AS have been shown to be similar to atherosclerosis. Consequently, coronary artery disease (CAD), peripheral vascular and carotid artery diseases are often found concurrently with diagnostic, procedural and prognostic implications. This study sought to describe comprehensive vascular assessment in terms of prevalence, severity and correlations in TAVI candidates. A total of 323 patients (81 ± 6 years) undergoing TAVI were enrolled. Vascular pathologies were evaluated by invasive coronary angiography, computer-tomography (abdominal aorta, renal, iliac and femoral arteries), echo-color Doppler ultrasound (carotid artery), and transoesophageal echocardiography (thoracic aorta). CAD was found in 173 (54%) patients, of which 65 (38%) had 1-vessel, 45 (26%) 2-vessel and 59 (34%) 3-vessel disease. Carotid artery disease was present in 33.6% patients, of which 23.6% unilateral and 10.0% bilateral. Iliac, femoral and renal stenosis were found in 29.2%, 22.0%, and 4.7%, respectively. Cardiovascular risk factor and gender correlated with CAD. CAD patients presented more frequently with significant stenosis (luminal narrowing ≥ 50%) of at least one other district. Multi-districts significant stenosis stratified patients on long-term survival and the coexistence of 3-districts involvement with CAD negatively impacts on mortality. Multimodality imaging assessment shows that coronary, carotid, and peripheral artery disease are often found concurrently in patients undergoing TAVI. Several risk factors and gender correlate with the presence and severity of CAD and peripheral pathologies. Long-term mortality is increased in patients with a more compromised vascular situation.

    Impaired nutrition is an important predictor of perioperative complications in lung cancer patients, and preoperative chemoradiotherapy increases the risk of such complications. The goal of this study was to assess the effect of an immune-enhancing diet on nutritional status in patients undergoing lung resection after chemoradiotherapy. We compared the preoperative nutritional status in 15 patients with lung cancer undergoing lung resection without chemoradiotherapy and 15 who had chemoradiotherapy. Body mass index and lymphocyte counts were lower in patients who had chemoradiotherapy. Although there was no difference in the rate of postoperative morbidity between groups, the chemoradiotherapy patients were more likely to have severe complications postoperatively. After chemoradiotherapy in 12 patients, 6 received oral Impact for 5 days, and 6 had a conventional diet before surgery. Oral intake of Impact for 5 days before surgery modified the decrease in transferrin and lymphocytes after the operation. Preoperative immunonutrition may improve the perioperative nutritional status after induction chemoradiotherapy in patients undergoing lung cancer surgery, and reduce the severity of postoperative complications. These potential benefits need to be confirmed in a randomized controlled trial.

    The need for a screening programme for spinal stenosis in children with achondroplasia undergoing limb lengthening was identified in a tertiary limb reconstruction service. The aim of this study was to evaluate whether screening would identify the 'at risk' group. A total of 26 achondroplastic patients underwent our screening programme. Canal diameters were measured by MRI. Neurosurgical interventions were recorded. Of the patients, 13 had severe foramen magnum narrowing. Six patients required single or multiple surgical decompressions. We identified female sex, delayed milestones and a tight cervicomedullary junction as high risks. We stress upon the importance of developing a nationalized screening programme with guidelines to identify a high-risk group. PMID:24345918

    While carotid interventions help decrease the risk of stroke, nearly 40% of patients experience cognitive deterioration. Genetic polymorphism in apolipoprotein E (ApoE) and brain-derived neurotrophic factor (BDNF) have been implicated in cognitive impairment; however, it is unclear whether they may influence cognitive changes in patients undergoing carotid intervention. In this study, we seek to assess the role of genetic polymorphisms in carotid intervention-related cognitive change. Polymorphisms related to cognitive function were chosen for this preliminary analysis. Over 2 years, patients undergoing carotid interventions were prospectively recruited. Patients underwent neuropsychological testing 2 weeks prior to and at 1 month following their procedure. Saliva samples were collected for genetic analysis. Logistic regressions were used to identify associations between polymorphisms and cognitive measures. A total of 91 patients were included; all were male with an average age of 70 years. The majority of patients exhibited hypertension (95%) and a history of smoking (81%). Presence of ApoE 4 allele was associated with depression (p= 0.047). After correcting for age and genetic polymorphisms in BDNF and serotonin transporter (5-HTT), ApoE 4 allele was associated with depression (p= 0.044) and showed a trend with baseline cognitive impairment (p= 0.10). Age ≥ 70 years was associated with baseline cognitive impairment after adjusting for the three genetic polymorphisms (p= 0.03). Patients with ApoE 4 and BDNF A polymorphisms performed less well on the visual and verbal memory measures, respectively. Polymorphisms in ApoE and BDNF may provide insight on cognition in patients undergoing carotid interventions; however, the mechanism of this relationship remains unclear. PMID:27574384

    Defibrotide pharmacokinetics were studied in 6 voluntary healthy subjects and in 10 uremic patients undergoing dialysis during which (instead of heparin) defibrotide was administered to prevent fibrino-formation in the circuit. Blood concentrations of the drug were assessed (expressed with reference to the residual glycidic deoxyribose) during a standard dialysis using defibrotide, 3.5, 15, 30, 45, 60 and 90 minutes after the defibrotide bolus (200 mg) had been injected into the arterial channel. The half-lives of the alpha and beta plasmatic phases were found to be equal at 3.79 and 41.4 min in dialysed subjects and at 1.13 and 16.54 in healthy volunteers. These results indicate that in uremic patients undergoing dialysis at intervals using defibrotide, a longer time is required to eliminate the drug from the circulation. This variation does not however appear to be significant in terms of the therapeutic use of the drug during dialysis.

    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.

    Glioblastoma multiforme (GBM) has associated with it one of the poorest prognoses among brain tumors. Postoperative seizures and the side effects of anticonvulsants, routinely given for prophylactic purposes, add to patient morbidity. The primary goal of this study was to determine who, of those undergoing craniotomy for GBM resection, is at risk for epilepsy. We studied 72 consecutive patients who underwent craniotomy and palliative resection for GBM. Twenty-nine presented with seizures and 17 had postoperative seizures. All patients were treated with a postoperative anticonvulsant for at least six months; anticonvulsants were continued longer if there was a postoperative seizure. Patient factors examined for an association with risk for postoperative seizure included age, sex, tumor size, tumor location, adjuvant therapy, postoperative complications and history of preoperative seizures. The majority of patients with no prior seizure history and who seized postoperatively had their first seizure after withdrawal from their anticonvulsant medication. All, but one, of the patients with both pre- and postoperative seizures had their first postoperative seizure while still on anticonvulsants. Smaller tumor size and frontal resection were associated with an increased risk of postoperative seizures. Our data suggests that those who do not present with seizures and undergo GBM resection may still be prone to seize but more easily protected from postoperative seizures with anticonvulsant therapy than patients who present with seizures; resection of frontal tumors and smaller tumors seemed to indicate an increased risk for postoperative seizures.

    Traditional coagulative parameters are of limited use in identifying perioperative coagulopathy occurring in patients undergoing major elective orthopedic surgery (MEOS). The aim of our study was to evaluate the coagulation changes in patients undergoing MEOS and to facilitate an early detection of perioperative coagulopathy in patients experiencing major intraoperative bleeding. We enrolled 40 consecutive patients (M/F 10/30, age range 34-90 years) who underwent MEOS at the Orthopedic Unit of the Padua University Hospital, Italy, between January 2014 and January 2015. Blood samples were obtained at the following time points: T0-pre: 30 min before surgery; T0-post: 30 min after the end of the procedure; T1: morning of the first postoperative day; T2: 7 ± 2 days after surgery. Patients who experienced an intraoperative blood loss ≥250 mL/h were considered as cases. Routine coagulative parameters, thromboelastometry and thrombin generation (TG) profiles were evaluated. At baseline, a significantly lower platelet count and FIBTEM MCF/AUC were observed in patents with excessive bleeding (p < 0.05 and 0.02/0.01, respectively). At T0-post and T1 intervals, cases showed hypocoagulation characterized by a significantly low platelet count (p = 0.001), prolonged CFT INTEM/EXTEM, reduction of alpha-angle and MaxV INTEM/EXTEM, MCF and AUC INTEM/EXTEM/FIBTEM (p < 0.05 in all comparisons). The only TG parameter standing out between study groups was time to peak at T0-pre. A low platelet count and fibrinogen activity were associated with significant intraoperative bleeding in patients undergoing MEOS. Thromboelastometry performed by ROTEM(®) identifies patients with coagulopathy. PMID:26951189

    General anesthesia and central neuraxial blockades in patients with severe Duchenne muscular dystrophy are associated with high risks of complications, including rhabdomyolysis, malignant hyperthermia, hemodynamic instability, and postoperative mechanical ventilation. Here, we describe peripheral nerve blocks as a safe approach to anesthesia in a patient with severe Duchenne muscular dystrophy who was scheduled to undergo surgery. A 22-year-old male patient was scheduled to undergo reduction and internal fixation of a left distal femur fracture. He had been diagnosed with Duchenne muscular dystrophy at 5 years of age, and had no locomotive capability except for that of the finger flexors and toe extensors. He had developed symptoms associated with dyspnea 5 years before and required intermittent ventilation. We blocked the femoral nerve, lateral femoral cutaneous nerve, and parasacral plexus under ultrasound on the left leg. The patient underwent a successful operation using peripheral nerve blocks with no complications. In conclusion general anesthesia and central neuraxial blockades in patients with severe Duchenne muscular dystrophy are unsafe approaches to anesthesia because of hemodynamic instability and respiratory depression. Peripheral nerve blocks are the best way to reduce the risks of critical complications, and are a safe and feasible approach to anesthesia in patients with severe Duchenne muscular dystrophy.

    OBJECTIVE--To determine whether thalamotomy leads to cognitive disturbances in patients with Parkinson's disease. METHODS--A total of 53 patients with Parkinson's disease undergoing stereotaxic ventrolateral thalamotomy for tremor and rigidity were tested for cognitive functions before and after surgery. The cognitive functions investigated involved visuospatial perception and memory. verbal memory, attention shift, and executive functions including set maintenance and shift. A neuropsychological test battery was used that contained the Wisconsin card sorting test, Street completion test, Stroop test, a dichotic memory listening test, and a facial recognition test. RESULTS--Clinically, a good or moderately good effect on parkinsonian symptoms was obtained in 50 patients. The neuropsychological investigations showed that the patients were impaired compared with healthy age matched control subjects on most tests, showing slight improvement postoperatively on verbal memory and visuospatial perception. No major differences were found between tests before and after operation, and there were no significant differences between patients undergoing surgery in the right or in the left thalamus. CONCLUSION--The study indicates that ventrolateral thalamotomy does not reduce the cognitive capacity in this group of patients. PMID:8778265

    The aim of this study was to determine if preemptive use of the NMDA receptor antogonist ketamine decreases postoperative pain in patients undergoing abdominal hystrectomy. A total of 60 patients admitted for total abdominal hysterectomy were included in this study after the approval of the ethic committee, and the patients were randomly classified into three groups. After standart general anaesthesia, before or after incision patients received bolus saline or ketamine. Group S received only saline while Group Kpre received ketamine 0.4 mg/kg before incision and saline after incision, and Group Kpost received saline before incision and 0.4 mg/kg ketamine after incision. Postoperatif analgesia was maintained with i.v. PCA morphine. Pain scores were assessed with Vizüal Analog Scale (VAS), Verbal Rating Scale (VRS) at 1., 2, 3., 4., 8., 12. ve 24. hours postoperatively. First analgesic requirement time, morphine consumption and side effects were recorded. There were no significant differences between groups with respect to VAS / VRS scores, the time for first analgesic dose, and morphine consumption ( p>0.05). Patients in Group S had significantly lower sedation scores than either of the ketamine treated groups ( p<0.05). In conclusion, a single dose of ketamin had no preemptive analgesic effect in patients undergoing abdominal hysterectomy, but further investigation is needed for different operation types and dose regimens.

    To minimize perioperative complications after orthopaedic procedures, patients may undergo medical optimization, which includes an assessment of their renal function and gastrointestinal (GI) system. The GI and renal systems are complex, and their proper optimization in the preoperative period can influence the success of any procedure. Several factors can prevent complications and reduce morbidity, mortality, and the cost of care, including a thorough evaluation and screening, with particular emphasis on anemia and its renal and GI causes; management of medications that are metabolized by the liver and excreted by the kidneys; and careful attention to the patient's nutritional status.

    The level of cytogenetic damage in peripheral blood lymphocytes of patients undergoing chemotherapy has been analyzed incisively 20 years ago. The results showed that the highest level of cytogenetic damage was observed at the end of therapy. In recent years, the doses of anticancer drugs were intensified thanks to the discovery of colony stimulating factors. Therefore, it was interesting to analyze the kinetics of micronuclei formation in lymphocytes of patients undergoing modern chemotherapy. The frequencies of micronuclei were measured in lymphocytes of 6 patients with small cell lung cancer treated with a combination of cisplatin and etoposide and 7 patients with ovarian carcinoma treated with a combination of taxol and cisplatin. 3 patients with lung cancer received radiotherapy in addition to chemotherapy. Micronuclei were analyzed in lymphocytes collected before the start of therapy and 1 day before each following cycle of chemotherapy. The micronucleus frequencies were compared with the kinetics of leukocyte counts. The micronucleus frequencies showed an interindividual variability. On average, the frequencies of micronuclei increased during the first half of therapy and declined thereafter, reaching, in some patients with ovarian carcinoma, values below the pre-treatment level. Leukocyte counts decreased strongly at the beginning of therapy with an upward trend at the end. We suggest that the decline of micronuclei was due to repopulation of lymphocytes and acquired drug resistance.

    Introduction Perioperative myocardial infarction adversely affects the prognosis of patients undergoing coronary artery bypass graft and its diagnosis was hampered by numerous difficulties, because the pathophysiology is different from the traditional instability atherosclerotic and the clinical difficulty to be characterized. Objective To identify the frequency of perioperative myocardial infarction and its outcome in patients undergoing coronary artery bypass graft. Methods Retrospective cohort study performed in a tertiary hospital specialized in cardiology, from May 01, 2011 to April 30, 2012, which included all records containing coronary artery bypass graft records. To confirm the diagnosis of perioperative myocardial infarction criteria, the Third Universal Definition of Myocardial Infarction was used. Results We analyzed 116 cases. Perioperative myocardial infarction was diagnosed in 28 patients (24.1%). Number of grafts and use and cardiopulmonary bypass time were associated with this diagnosis and the mean age was significantly higher in this group. The diagnostic criteria elevated troponin I, which was positive in 99.1% of cases regardless of diagnosis of perioperative myocardial infarction. No significant difference was found between length of hospital stay and intensive care unit in patients with and without this complication, however patients with perioperative myocardial infarction progressed with worse left ventricular function and more death cases. Conclusion The frequency of perioperative myocardial infarction found in this study was considered high and as a consequence the same observed average higher troponin I, more cases of worsening left ventricular function and death.

    Objective. Postoperative hyperalgesia is very frequent and hard to treat. Dezocine is widely used and has a modulatory effect for thermal hyperalgesia in animal models. So, this study was designed to investigate the potential role of dezocine in decreasing postoperative hyperalgesia for patients undergoing open abdominal surgery. Methods. This is a randomized, double-blinded, and placebo-controlled trial. 50 patients for elective open gastrectomy were randomly allocated to either a true treatment group (0.15 mg/kg intravenous dezocine at the end of surgery) or a sham treatment group (equivalent volume of saline) in a 1 : 1 ratio. Patients were followed up for 48 hours postoperatively and pain threshold to Von Frey filaments, pain scores, PCIA consumption, rescue analgesics use, sedation score, and occurrence of postoperative nausea and vomiting were recorded. Results. Patients in the true treatment group experienced statistically significantly higher pain threshold on forearm and smaller extent of peri-incisional hyperalgesia than the sham treatment group. Rescue analgesic use, cumulative PCIA consumption, and pain scores were statistically significantly decreased in the true treatment group compared to the sham treatment group. Conclusions. Dezocine offers a significant antihyperalgesic and analgesic effect in patients undergoing elective open gastrectomy for up to 48 hours postoperatively. PMID:26170890

    Background: In India the incidence of end stage renal disease (ESRD) is increasing day by day and the option for the treatment of ESRD is dialysis or transplantation. In the present scenario, due to the cost of treatment normal people can afford only hemodialysis rather than transplantation. Since the cost of hemodialysis differs across the country, research is needed to evaluate its exact cost. Aim: This study is to analyze the healthcare cost of hemodialysis in a private hospital of South India. Materials and Methods: This is a prospective, observational study carried out in a tertiary care hospital. Patients who are undergoing routine hemodialysis in this hospital were selected for the study. Patient data as well as cost details were collected for a period of six months. Thirty patients were selected for the study and a total of 2160 dialysis sessions were studied. Patient perspective was taken for the analysis of cost. Both direct and indirect costs were analyzed. This includes cost of dialysis, investigations, erythropoietin, food, transportation, lost wages etc. Socioeconomic status of the patient was also studied. Result: The total cost per session was found to be around Rs. 4500. Fifty six percent contributes direct medical cost whereas 20% contributes direct non medical cost. Twenty four percent cost was due to indirect costs. Since the patients are paying from their own pocket, only the upper or upper middle class patient can undergo hemodialysis regularly. Conclusion: These findings are important to find out the impact of cost of hemodialysis on patients suffering from ESRD. Further studies related to costs and outcome, otherwise known as pharmacoeconomic studies, are needed to analyze the pros and cons of renal replacement therapy and to improve the quality of life of ESRD patients. Thus pharmacoeconomical studies are needed to realize that government has to take initiative to provide insurance or reimbursement for the common people. PMID:22557920

    The increasing prevalence and complexity of fluoroscopically guided interventions (FGI) raises concern regarding radiation dose to patients subjected to the procedure. Despite current evidence showing the risk to patients from the deterministic effects of radiation (e.g. skin burns), radiation induced injuries remain commonplace. This review aims to increase the awareness surrounding radiation dose measurement for patients undergoing FGI. A review of the literature was conducted alongside previous researches from the authors’ department. Studies pertaining to patient dose measurement, its formalism along with current advances and present challenges were reviewed. Current patient monitoring techniques (using available radiation dosimeters), as well as the inadequacy of accepting displayed dose as patient radiation dose is discussed. Furthermore, advances in real-time patient radiation dose estimation during FGI are considered. Patient dosimetry in FGI, particularly in real time, remains an ongoing challenge. The increasing occurrence and sophistication of these procedures calls for further advances in the field of patient radiation dose monitoring. Improved measuring techniques will aid clinicians in better predicting and managing radiation induced injury following FGI, thus improving patient care.

    Abstract Background: The existence of peripheral opioid receptors and its effectiveness in peripheral nerve block remain controversial. The aim of this prospective, randomized, double-blinded study was to examine the analgesic effects of adding fentanyl to ropivacaine for continuous femoral nerve block (CFNB) using patient-controlled analgesia after total knee arthroplasty (TKA). Methods: The patients were divided into 2 groups, each with n = 40 in ropivacaine (R) group and n = 42 in R with fentanyl (R + F) group. After operation, the patients in each group received R + F and R alone via a femoral nerve catheter, respectively. We assessed the visual analog scale (VAS) pain immediately before administration (baseline) and at 15, 30, and 60 minutes on postanesthesia care unit (PACU), and resting and ambulatory VAS score up to 24 hours. Results: Overall, the average VAS scores in the R + F group were slightly lower than those of the R group. However, the VAS score differences between groups were not statistically significant, except for 30 minutes (P = 0.009) in PACU. R group showed higher supplemental analgesics consumption in average compared with R + F group, but not significant. Conclusion: Additional fentanyl did not show prominent enhancement of analgesic effect in the field of CFNB after TKA. PMID:27603376

    As a reflection of the increasing global incidence of obesity, there has been a corresponding rise in the proportion of obese patients undergoing major surgery. This review reports the physiological effect of these changes in body composition on the respiratory system and discusses the clinical approach required to maximize safety and minimize the risk to the patient. The changes in respiratory system compliance and lung volumes, which can adversely affect pulmonary gas exchange, combined with upper airways obstruction and sleep-disordered breathing need to be considered carefully in the peri-operative period. Indeed, these challenges in the obese patient have led to a clear focus on the clinical management strategy and development of peri-operative pathways, including pre-operative risk assessment, patient positioning at induction and under anesthesia, modified approach to intraoperative ventilation and the peri-operative use of non-invasive ventilation (NIV) and continuous positive airways pressure.

    Sarcopenia is characterized by muscle mass depletion and decrease in muscle power or physical activity. We evaluated significance of sarcopenia in patients undergoing living donor liver transplantation (LDLT). Patients with low skeletal muscle mass (SMM) had significantly worse survival compared with patients with normal/high SMM (p < 0.001). Correlations of preoperative zinc with prealbumin and branched-chain amino acids were significantly positive. While, correlations of zinc with tyrosine and ammonia levels were significantly negative. The low pre-transplant zinc level steeply dropped for 2/3 days after LDLT and subsequently increased back to reach the pre-transplant level around the postoperative day 5, and continued to increase until normalized during 2 weeks. Perioperative nutritional therapy including zinc supplement significantly increased survival in patients with low SMM (p = 0.009). PMID:27455815

    Capsulotomy is an established psychosurgical intervention for anxiety disorders. While the effectiveness of the intervention in reducing target symptoms is undisputed, the issue of negative personality changes following capsulotomy is of great concern. We studied prospectively personality traits in nine consecutive patients undergoing capsulotomy for anxiety disorder, using the Rorschach test and a personality inventory, the Karolinska Scales of Personality (KSP), administered before and one year after operation. The protocols were evaluated under blind conditions by an independent assessor who had access to no data other than the age and sex of the patients. The Rorschach findings were used in two main comparison procedures: between the patients pre- and postoperative scores, and between that group and three reference groups. The KSP data were compared both with an age-stratified non-patient control group and with data obtained from groups of neurotic patients. In summary, the capsulotomy patients' personalities, as expressed in their Rorschach interpretations, remained intact, and significant reductions were noted in scales reflecting anxiety and hospitality. Statistically significant changes were also noted after operation in 10 of the 17 scales included in the KSP. While pathological scores were observed preoperatively in many scales, all the postoperative scores but one (Socialization) were within the normal range. Scores on the Socialization scale remained low, which is often the case in chronic patients. It is concluded that the patients displayed more normal personality features after operation than before and that adverse personality changes are not likely to occur after capsulotomy. PMID:3223360

    Aim: The aim of this study was to describe our institutional experience, primarily with general anesthesiologists consulting with cardiac anesthesiologists, caring for left ventricular assist device (LVAD) patients undergoing noncardiac surgery. Materials and Methods: This is a retrospective review of the population of patients with LVADs at a single institution undergoing noncardiac procedures between 2009 and 2014. Demographic, perioperative, and procedural data collected included the type of procedure performed, anesthetic technique, vasopressor requirements, invasive monitors used, anesthesia provider type, blood product management, need for postoperative intubation, postoperative disposition and length of stay, and perioperative complications including mortality. Statistical Analysis: Descriptive statistics for categorical variables are presented as frequency distributions and percentages. Continuous variables are expressed as mean ± standard deviation and range when applicable. Results: During the study, 31 patients with LVADs underwent a total of 74 procedures. Each patient underwent an average of 2.4 procedures. Of the total number of procedures, 48 (65%) were upper or lower endoscopies. Considering all procedures, 81% were performed under monitored anesthesia care (MAC). Perioperative care was provided by faculty outside of the division of cardiac anesthesia in 62% of procedures. Invasive blood pressure monitoring was used in 27 (36%) procedures, and a central line, peripherally inserted central catheter or midline was in place preoperatively and used intraoperatively for 38 (51%) procedures. Vasopressors were not required in the majority (65; 88%) of procedures. There was one inhospital mortality secondary to multiorgan failure; 97% of patients survived to discharge after their procedure. Conclusion: At our institution, LVAD patients undergoing noncardiac procedures most frequently require endoscopy. These procedures can frequently be done safely under

    Objective. The aim of this prospective, randomized study was to investigate the effects of low-flow sevoflurane anesthesia on the pulmonary functions in patients undergoing laparoscopic cholecystectomy. Methods. Sixty American Society of Anesthesiologists (ASA) physical status classes I and II patients scheduled for elective laparoscopic cholecystectomy were included in the study. Patients were randomly allocated to two study groups: high-flow sevoflurane anesthesia group (Group H, n = 30) and low-flow sevoflurane anesthesia group (Group L, n = 30). The fresh gas flow rate was of 4 L/min in high-flow sevoflurane anesthesia group and 1 L/min in low-flow sevoflurane anesthesia group. Heart rate (HR), mean arterial blood pressure (MABP), peripheral oxygen saturation (SpO2), and end-tidal carbon dioxide concentration (ETCO2) were recorded. Pulmonary function tests were performed before and 2, 8, and 24 hours after surgery. Results. There was no significant difference between the two groups in terms of HR, MABP, SpO2, and ETCO2. Pulmonary function test results were similar in both groups at all measurement times. Conclusions. The effects of low-flow sevoflurane anesthesia on pulmonary functions are comparable to high-flow sevoflurane anesthesia in patients undergoing laparoscopic cholecystectomy. PMID:27413741

    Cardiovascular disease is one of the leading causes of death in patients with advanced renal disease. The objective of this study was to investigate impairments in heart rhythm complexity in patients with end-stage renal disease. We prospectively analyzed 65 patients undergoing peritoneal dialysis (PD) without prior cardiovascular disease and 72 individuals with normal renal function as the control group. Heart rhythm analysis including complexity analysis by including detrended fractal analysis (DFA) and multiscale entropy (MSE) were performed. In linear analysis, the PD patients had a significantly lower standard deviation of normal RR intervals (SDRR) and percentage of absolute differences in normal RR intervals greater than 20 ms (pNN20). Of the nonlinear analysis indicators, scale 5, area under the MSE curve for scale 1 to 5 (area 1–5) and 6 to 20 (area 6–20) were significantly lower than those in the control group. In DFA anaylsis, both DFA α1 and DFA α2 were comparable in both groups. In receiver operating characteristic curve analysis, scale 5 had the greatest discriminatory power for two groups. In both net reclassification improvement model and integrated discrimination improvement models, MSE parameters significantly improved the discriminatory power of SDRR, pNN20, and pNN50. In conclusion, PD patients had worse cardiac complexity parameters. MSE parameters are useful to discriminate PD patients from patients with normal renal function.

    Purpose: Recently, performance of cardiac surgery in hemodialysis patients has increased, but the mortality rate is high. Methods: We retrospectively examined the early and long-term outcomes in 128 dialysis patients who underwent cardiac surgery with or without carperitide infusion and were followed for 2 years. Sixty-three patients received carperitide infusion during surgery and 65 patients did not. Results: The hospital mortality rate was 1.6% in the carperitide group and 12.3% in the non-carperitide group, being significantly lower in the carperitide group. The 2-year actuarial survival rate was 90.5% ± 3.7% in the carperitide group, and 76.9% ± 5.2% in the non-carperitide group, while the major adverse cardiovascular and cerebrovascular events (MACCE)-free rate at 2 years postoperatively was 90.5% ± 3.7% in the carperitide group and 67.7% ± 5.8% in the non-carperitide group. Conclusions: These findings suggest that carperitide improves the early postoperative outcome in dialysis patients undergoing cardiac surgery, as has already been demonstrated in non-dialysis patients. An early postoperative cardioprotective effect of carperitide and improvement of renal function in oliguric patients might have contributed to this outcome. However, this was a retrospective study, so a prospective investigation is required to demonstrate the mechanisms involved. In addition, further evaluation of the long-term results would be desirable. PMID:27025780

    BACKGROUND Pericardial effusion (PE) is common in cancer patients but the optimal therapeutic approach is not well defined. Percutaneous pericardiocentesis is less invasive than surgery, but its long-term effectiveness and safety are not well documented. OBJECTIVES We evaluated outcomes of cancer patients undergoing percutaneous pericardiocentesis for PE and assessed the procedure’s safety in patients with thrombocytopenia. METHODS Cancer patients who underwent percutaneous pericardiocentesis for PE between November 2009 and October 2014 at MD Anderson Cancer Center were included. Procedure-related complications, effusion recurrence rate, and overall survival were analyzed. RESULTS Of 1,645 cancer patients referred for PE, 212 (13%) underwent percutaneous pericardiocentesis. The procedure was successful in 99% of the cases with no procedure-related deaths. Four patients had major procedure-related bleeding that did not vary by platelet count <50,000/µl or ≥50,000/µl (p = 0.1281). Patients with catheter drainage for 3 to 5 days had the lowest recurrence rate (10%). Median overall survival was 143 days with age >65 years, lung cancer, platelet count <20,000/µl, and malignant pericardial fluid independently associated with poor prognosis. Lung cancer patients with proven malignant effusions had a significantly shorter median 1-year survival compared to those with nonmalignant effusions (16.2% vs. 49.0%, respectively; log-rank test p value = 0.0101). A similar difference in 1-year survival was not observed in breast cancer patients (40.2% vs. 40.0%, respectively; log-rank test p = 0.4170). CONCLUSION Percutaneous pericardiocentesis with extended catheter drainage, as primary treatment for PE in cancer patients, is safe and effective, including in those with thrombocytopenia. Malignant PE significantly shortens the survival outcome of lung, but not breast, cancer patients. PMID:26337990

    Background Patients undergoing treatment for malignant gliomas (MGs) can encounter medical costs beyond what their insurance covers. The magnitude and type of costs experienced by patients are unknown. The purpose of this study was to have patients or their families report on the medical costs incurred during the patients MG treatment. Methods Patients with MG were eligible if they were within 6 months of diagnosis or tumor recurrence. Patients had to be ≥18 years of age, fluent in English, and not aphasic. Weekly logbooks were issued to patients for recording associated costs for ∼6 months or until tumor progression. “Out-of-pocket” (OOP) costs included medical and nonmedical expenses that were not reimbursed by insurance. Direct medical costs included hospital and physician bills. Direct nonmedical costs included transportation, parking, and other related items. Indirect medical costs included lost wages. Costs were analyzed to provide mean and medians with range of expenses. Results Forty-three patients provided cost data for a median of 12 weeks. There were 25 men and 18 women with a median age of 57 years (range, 24y–73y); 79% were married, and 49% reported annual income >$75 000. Health insurance coverage was preferred provider organizations for 58% of patients, and median deductible was $1 500. Median monthly OOP cost was $1 342 (mean, $2 451; range, $333.41–$17 267.16). The highest OOP median costs were medication copayments ($710; range, $0–13 611.20), transportation ($327; range, $0–$1 927), and hospital bill copayments ($403; range, $0–$4 000). Median lost wages were $7 500, and median lost days of work were 12.8. Conclusions OOP costs for MG patients can be significant and comprise direct and indirect costs across several areas. Informing patients about expected costs could limit additional duress and allow financial support systems to be implemented. PMID:26034619

    Background Body weight has been increasing in the general population and is an established risk factor for hypertension, diabetes, and all-cause and cardiovascular mortality. Patients undergoing peritoneal dialysis (PD) gain weight, mainly during the first months of treatment. The aim of this study was to assess the relationship between body composition and metabolic and inflammatory status in patients undergoing PD. Methods This was a prospective, non-interventional study of prevalent patients receiving PD. Body composition was studied every 3 months using bioelectrical impedance (BCM®). We performed linear regression for each patient, including all BCM® measurements, to calculate annual changes in body composition. Thirty-one patients in our PD unit met the inclusion criteria. Results Median follow-up was 26 (range 17–27) months. Mean increase in weight was 1.8 ± 2.8 kg/year. However, BCM® analysis revealed a mean increase in fat mass of 3.0 ± 3.2 kg/year with a loss of lean mass of 2.3 ± 4.1 kg/year during follow-up. The increase in fat mass was associated with the conicity index, suggesting that increases in fat mass are based mainly on abdominal adipose tissue. Changes in fat mass were directly associated with inflammation parameters such as C-reactive protein (r = 0.382, P = 0.045) and inversely associated with high-density lipoprotein cholesterol (r=−0.50, P = 0.008). Conclusions Follow-up of weight and body mass index can underestimate the fat mass increase and miss lean mass loss. The increase in fat mass is associated with proinflammatory state and alteration in lipid profile. PMID:27274820

    Purpose. Patients may not achieve a clinical benefit after percutaneous cholecystostomy due to the inherent difficulty in identifying patients who truly have infected gallbladders. We attempted to identify imaging and biochemical parameters which would help to predict which patients have infected gallbladders. Methods. A retrospective review was performed of 52 patients undergoing percutaneous cholecystostomy for clinical suspicion of acute cholecystitis in whom bile culture results were available. Multiple imaging and biochemical variables were examined alone and in combination as predictors of infected bile, using logistic regression. Results. Of the 52 patients, 25 (48%) had infected bile. Organisms cultured included Enterococcus, Enterobacter, Klebsiella, Pseudomonas, E. coli, Citrobacter and Candida. No biochemical parameters were significantly predictive of infected bile; white blood cell count >15,000 was weakly associated with greater odds of infected bile (odds ratio 2.0, p = NS). The presence of gallstones, sludge, gallbladder wall thickening and pericholecystic fluid by ultrasound or CT were not predictive of infected bile, alone or in combination, although a trend was observed among patients with CT findings of acute cholecystitis toward a higher 30-day mortality. Radionuclide scans were performed in 31% of patients; all were positive and 66% of these patients had infected bile. Since no patient who underwent a radionuclide scan had a negative study, this variable could not be entered into the regression model due to collinearity. Conclusion. No single CT or ultrasound imaging variable was predictive of infected bile, and only a weak association of white blood cell count with infected bile was seen. No other biochemical parameters had any association with infected bile. The ability of radionuclide scanning to predict infected bile was higher than that of ultrasound or CT. This study illustrates the continued challenge to identify bacterial cholecystitis

    Antimicrobial therapy may cause changes in the resident oral microbiota, with the increase of opportunistic pathogens. The aim of this study was to compare the prevalence of Candida, Staphylococcus, Pseudomonas and Enterobacteriaceae in the oral cavity of fifty patients undergoing antibiotic therapy for pulmonary tuberculosis and systemically healthy controls. Oral rinsing and subgingival samples were obtained, plated in Sabouraud dextrose agar with chloramphenicol, mannitol agar and MacConkey agar, and incubated for 48 h at 37°C. Candida spp. and coagulase-positive staphylococci were identified by phenotypic tests, C. dubliniensis, by multiplex PCR, and coagulase-negative staphylococci, Enterobacteriaceae and Pseudomonas spp., by the API systems. The number of Candida spp. was significantly higher in tuberculosis patients, and C. albicans was the most prevalent specie. No significant differences in the prevalence of other microorganisms were observed. In conclusion, the antimicrobial therapy for pulmonary tuberculosis induced significant increase only in the amounts of Candida spp. PMID:24031759

    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

    The purpose of this retrospective study was to compare functional dysphagia outcomes following inpatient rehabilitation for patients with brain tumors with that of patients following a stroke. Group 1 (n = 24) consisted of consecutive admissions to the brain injury program with the diagnosis of brain tumor and dysphagia. Group 2 (n = 24) consisted of matched, consecutive admissions, with the diagnosis of acute stroke and dysphagia. Group 2 was matched for age, site of lesion, and initial composite cognitive FIM score. The main outcome measures for this study included the American Speech-Language-Hearing Association (ASHA) National Outcome Measurement System (NOMS) swallowing scale, length of stay, hospital charges, and medical complications. Results showed that swallowing gains made by both groups as evaluated by the admission and discharge ASHA NOMS levels were considered to be statistically significant. The differences for length of stay, total hospital charges, and speech charges between the two groups were not considered to be statistically significant. Three patients in the brain tumor group (12.5%) demonstrated dysphagia complications of either dehydration or pneumonia during their treatment course as compared to 0% in the stroke group. This study confirms that functional dysphagia gains can be achieved for patients with brain tumors undergoing inpatient rehabilitation and that they should be afforded the same type and intensity of rehabilitation for their swallowing that is provided to patients following a stroke.

    In an attempt to determine whether noninvasive cardiac testing could be used to assess cardiac risk in patients undergoing surgery for vascular disease, the authors studied 96 patients. Seventy-seven patients eventually underwent major vascular surgery with 11 (14%) experiencing a significant cardiac complication. Thallium imaging was much more likely to be positive (p less than 0.01) in patients with a cardiac complication; however, there was a significant number of patients with cardiac complications who had a positive history or electrocardiogram for myocardial infarction. When grouped by complication and history of infarction, thallium imaging, if negative, correctly predicted low cardiac risk in the group with a history of infarction. Thallium imaging, however, did not provide a clear separation of risk in those without a history of infarction. Age and coronary angiography, on the other hand, did reveal significant differences within the group without a history of infarction. The resting radionuclide ejection fraction followed a similar pattern to thallium imaging. It is concluded that a positive history of myocardial infarction at any time in the past is the strongest risk predictor in this population and that the predictive value of noninvasive testing is dependent on this factor. Considering these findings, a proposed scheme for assessing risk that will require further validation is presented.

    Peripheral tissues, such as skin and muscles, are sensitive to alterations in perfusion. During circulatory shock, these tissues are the first to receive less blood and the last to recover after treatment. By monitoring peripheral circulation, disturbance of the systemic circulation can be detected at an early stage. Peripheral perfusion is often disturbed in critically ill patients. Peripheral perfusion may remain disturbed, even if conventional hemodynamic parameters such as blood pressure and heart frequency normalize after treatment. Persistent abnormal peripheral perfusion is related to a poorer clinical course. With current non-invasive methods, peripheral circulation in critically ill patients can easily be assessed at the bedside. Interventions that improve peripheral circulation may speed up recovery in critically ill patients.

    The elderly constitute a continuously increasing social group of the Hellenic, but also of the global population. This phenomenon is also evident in the haemodialysis patient population, which grows continually. Faced with this reality, Nursing is obliged to adapt itself and, in this effort that it is putting forward it has achieved many positive steps (geriatric nursing). It is imperative however for nursing that there is a particular way of dealing with the elderly, especially those that undergo chronic periodic haemodialysis, which regards as much the problems stemming from the disease, as it regards their grave psychological condition. The objective of our study was to develop the need for the presence of the Nephrology Nurse in the psychological support of the elderly renal patient and we have been able to define: level of communication, level of dietetic information, psycho-social condition and restrictions imposed by the disease. 30 patients (age 65-80, mean 72.92 years) were included with an observation time of 3 years, less than 60% responded positively to the efforts for psychological support, on the basis of the studied factors. The rest did not show any willingness to answer. We conclude that psychological support is of paramount importance for these patients but also that the Nephrology Nurse has not yet discovered and detected some unknown aspects of the different problems arising due to insufficient knowledge of geriatric caring.

    Background The obesity has achieved an alarming increase in recent years, which led this disease to global epidemic condition. Aim To evaluate the nutritional status as well as the quality of life of obese patients undergoing bariatric surgery. Methods A transversal study was conducted with obese adults of both genders who underwent bariatric surgery by Fobi-Capella technique for at least 30 days. It was evaluated: age, gender, marital status, occupation, weight before surgery, current weight, height, preoperative and current BMI, weight loss and loss of excess weight percentages, presence of clinical manifestations and food intolerances. Results The sample consisted of 70 patients, being 81.4% female, 37.1% aged 30 to 39 years, 58.6% were married, 41.4% have undergone the bariatric surgery in the last 12 months. It was observed a reduction in BMI from 37.2 kg/m2 (one to three months) to 28.9 kg/m2 (>12 months) and consequent increase in weight loss and loss of excess weight percentages. The most frequent clinical manifestation was alopecia (62.9%). The most reported food intolerance was on the red meat (24%). According to the Baros questionnaire, 50% of patients were classified as having good quality of life. Conclusion The operation of Fobi-Capella proved to be effective in promoting gradual and lasting weight loss. Quality of life was considered good in most patients, indicating that the operation had a positive impact on their lives. PMID:25409963

    Background Patients with end stage renal disease often fail to follow prescribed dietary and fluid regimen, leading to undesirable outcomes. This study aimed to examine and identify factors influencing dietary, fluid, medication and dialysis compliance behaviours in patients undergoing hemodialysis. Methods This was a cross-sectional study which employed purposive sampling design. A total of 188 respondents were recruited from 14 dialysis centres in Malaysia between 2008–2011. Self-reported compliance behaviours and biochemical measurements were used as evaluation tools. Results Compliance rates of dietary, fluid, medication and dialysis were 27.7%, 24.5%, 66.5% and 91.0%, respectively. Younger, male, working patients and those with longer duration on hemodialysis were found more likely to be non-compliant. Lacks of adequate knowledge, inadequate self-efficacy skills, forgetfulness and financial constraints were the major perceived barriers towards better compliance to fluid, dietary, medication and dialysis, respectively. Conclusions Healthcare professionals should recognise the factors hindering compliance from the patients' perspective while assisting them with appropriate skills in making necessary changes possible.

    Background Surgery is the treatment of choice for patients with non-small cell lung cancer (NSCLC) stages I-IIIA. However, more than 20% of these patients develop recurrence and die due to their disease. The release of tumor cells into peripheral blood (CTCs) is one of the main causes of recurrence of cancer. The objectives of this study are to identify the prognostic value of the presence and characterization of CTCs in peripheral blood in patients undergoing radical resection for NSCLC. Patients and Methods 56 patients who underwent radical surgery for previously untreated NSCLC were enrolled in this prospective study. Peripheral blood samples for CTC analysis were obtained before and one month after surgery. In addition CTCs were phenotypically characterized by epidermal growth factor receptor (EGFR) expression. Results 51.8% of the patients evaluated were positive with the presence of CTCs at baseline. A decrease in the detection rate of CTCs was observed in these patients one month after surgery (32.1%) (p = 0.035). The mean number of CTCs was 3.16 per 10 ml (range 0–84) preoperatively and 0.66 (range 0–3) in postoperative determination. EGFR expression was found in 89.7% of the patients at baseline and in 38.9% patients one month after surgery. The presence of CTCs after surgery was significantly associated with early recurrence (p = 0.018) and a shorter disease free survival (DFS) (p = .008). In multivariate analysis CTC presence after surgery (HR = 5.750, 95% CI: 1.50–21.946, p = 0.010) and N status (HR = 0.296, 95% CI: 0.091–0.961, p = 0.043) were independent prognostic factors for DFS. Conclusion CTCs can be detected and characterized in patients undergoing radical resection for non-small cell lung cancer. Their presence might be used to identify patients with increased risk of early recurrence. PMID:26913536

    Summary Background and objectives Fibroblast growth factor 23 (FGF23) is an independent risk factor for mortality in patients with ESRD. Before FGF23 testing can be integrated into clinical practice of ESRD, further understanding of its determinants is needed. Design, setting, participants, & measurements In a study of 67 adults undergoing peritoneal dialysis, we tested the hypothesis that longer dialysis vintage and lower residual renal function and renal phosphate clearance are associated with higher FGF23. We also compared the monthly variability of FGF23 versus parathyroid hormone (PTH) and serum phosphate. Results In unadjusted analyses, FGF23 correlated with serum phosphate (r = 0.66, P < 0.001), residual renal function (r = −0.37, P = 0.002), dialysis vintage (r = 0.31, P = 0.01), and renal phosphate clearance (r = −0.38, P = 0.008). In adjusted analyses, absence of residual renal function and greater dialysis vintage associated with higher FGF23, independent of demographics, laboratory values, peritoneal dialysis modality and adequacy, and treatment with vitamin D analogs and phosphate binders. Urinary and dialysate FGF23 clearances were minimal. In three serial monthly measurements, within-subject variability accounted for only 10% of total FGF23 variability compared with 50% for PTH and 60% for serum phosphate. Conclusions Increased serum phosphate, loss of residual renal function, longer dialysis vintage, and lower renal phosphate clearance are associated with elevated FGF23 levels in ESRD patients undergoing peritoneal dialysis. FGF23 may be a more stable marker of phosphate metabolism in ESRD than PTH or serum phosphate. PMID:21903990

    The aim of this study was to investigate the activity of myoinositol, in a court of 217 PCOS women undergoing intracytoplasmic sperm injection (ICSI), on pregnancy rate, embryo development, estradiol, and progesterone concentration in blood serum, superoxide dismutase (SOD), and catalase (CAT) in follicular fluid. Concerning the court of patient, 112 (groups I and II) out of 217 were PCOS women, whereas group III consisted of healthy subjects (not PCOS). Group I patients were treated with 400 μg of folic acid per day for 3 months before ICSI, whereas group II patients received 4000 mg of myoinositol and 400 μg of folic acid per day for 3 months before ICSI. Group II revealed a shorter embryo/blastocyst development period between microinjection and 5-cell stage compared to group I. The difference in SOD concentration between groups I and II and between groups II and III was statistically significant. In group II, 34.62% of pregnancies were obtained, whereas in group I this number reached 20% (NS). Myoinositol increased embryo development dynamics and accelerated blastocyst stage reaching time; however, no effect was shown on clinical pregnancy. Furthermore, it restored SOD concentration, lowered in PCOS women, but did not exert any effect on CAT concentration. PMID:27777587

    Objective Prior studies have suggested treatment and outcome disparities between men and women for lower extremity peripheral arterial disease after surgical bypass. Given the recent shift toward endovascular therapy, which has increasingly been used to treat claudication, we sought to analyze sex disparities in presentation, revascularization, amputation, and inpatient mortality. Methods We identified individuals with intermittent claudication and critical limb ischemia (CLI) using International Classification of Diseases, Ninth Revision codes in the Nationwide Inpatient Sample from 1998 to 2009. We compared presentation at time of intervention (intermittent claudication vs CLI), procedure (open surgery vs percutaneous transluminal angioplasty or stenting vs major amputation), and in-hospital mortality for men and women. Regional and ambulatory trends were evaluated by performing a separate analysis of the State Inpatient and Ambulatory Surgery Databases from four geographically diverse states: California, Florida, Maryland, and New Jersey. Results From the Nationwide Inpatient Sample, we identified 1,797,885 patients (56% male) with intermittent claudication (26%) and CLI (74%), who underwent 1,865,999 procedures (41% open surgery, 20% percutaneous transluminal angioplasty or stenting, and 24% amputation). Women were older at the time of intervention by 3.5 years on average and more likely to present with CLI (75.9% vs 72.3%; odds ratio [OR], 1.21; 95% confidence interval [CI], 1.21–1.23; P < .01). Women were more likely to undergo endovascular procedures for both intermittent claudication (47% vs 41%; OR, 1.27; 95% CI, 1.25–1.28; P < .01) and CLI (21% vs 19%; OR, 1.14; 95% CI, 1.13–1.15; P < .01). From 1998 to 2009, major amputations declined from 18 to 11 per 100,000 in men and 16 to 7 per 100,000 in women, predating an increase in total CLI revascularization procedures that was seen starting in 2005 for both men and women. In-hospital mortality was

  2. Radiation Dose Estimation for Pediatric Patients Undergoing Cardiac Catheterization

    NASA Astrophysics Data System (ADS)

    Wang, Chu

    Patients undergoing cardiac catheterization are potentially at risk of radiation-induced health effects from the interventional fluoroscopic X-ray imaging used throughout the clinical procedure. The amount of radiation exposure is highly dependent on the complexity of the procedure and the level of optimization in imaging parameters applied by the clinician. For cardiac catheterization, patient radiation dosimetry, for key organs as well as whole-body effective, is challenging due to the lack of fixed imaging protocols, unlike other common X-ray based imaging modalities. Pediatric patients are at a greater risk compared to adults due to their greater cellular radio-sensitivities as well as longer remaining life-expectancy following the radiation exposure. In terms of radiation dosimetry, they are often more challenging due to greater variation in body size, which often triggers a wider range of imaging parameters in modern imaging systems with automatic dose rate modulation. The overall objective of this dissertation was to develop a comprehensive method of radiation dose estimation for pediatric patients undergoing cardiac catheterization. In this dissertation, the research is divided into two main parts: the Physics Component and the Clinical Component. A proof-of-principle study focused on two patient age groups (Newborn and Five-year-old), one popular biplane imaging system, and the clinical practice of two pediatric cardiologists at one large academic medical center. The Physics Component includes experiments relevant to the physical measurement of patient organ dose using high-sensitivity MOSFET dosimeters placed in anthropomorphic pediatric phantoms. First, the three-dimensional angular dependence of MOSFET detectors in scatter medium under fluoroscopic irradiation was characterized. A custom-made spherical scatter phantom was used to measure response variations in three-dimensional angular orientations. The results were to be used as angular dependence

    Improvement in quality of life (QoL) is a primary treatment goal for patients with peripheral arterial disease (PAD). The current study aimed to quantify improvement in the health status of PAD patients following peripheral revascularization using the peripheral artery questionnaire (PAQ) and ankle-brachial index (ABI), and to evaluate possible correlation between the two methods. The PAQ and ABI were assessed in 149 symptomatic PAD patients before, and three months after peripheral revascularization. Mean PAQ summary scores improved significantly three months after revascularization (+49.3 ± 15 points, p < 0.001). PAQ scores relating to patient symptoms showed the largest improvement following revascularization. The smallest increases were seen in reported treatment satisfaction (all p's < 0.001). As expected the ABI of treated limbs showed significant improvement post-revascularization (p < 0.001). ABI after revascularization correlated with patient-reported changes in the physical function and QoL domains of the PAQ. Twenty-two percent of PAD patients were identified as having a poor response to revascularization (increase in ABI < 0.15). Interestingly, poor responders reported improvement in symptoms on the PAQ, although this was less marked than in patients with an increase in ABI > 0.15 following revascularization. In conclusion, data from the current study suggest a significant correlation between improvement in patient-reported outcomes assessed by PAQ and ABI in symptomatic PAD patients undergoing peripheral revascularization.

    Background Renal impairment is a known predictor of mortality in both the general population and in patients with cardiac disease. The aim of this study was to evaluate factors that determine mortality in patients with chronic kidney disease (CKD) who have undergone percutaneous coronary intervention (PCI). Methods In this study we included 293 consecutive patients with CKD who underwent PCI between 1st January 2007 and 30th September 2012. The primary outcome that we studied was all-cause mortality in a follow-up period of 12-69 months (mean 38.8 ± 21.7). Results Age (p < 0.001), PCI indication (p = 0.035), CKD stage (p < 0.001) and left ventricular ejection fraction (p < 0.001) were significantly related to mortality. CKD stage 5 [hazard ratio (HR) = 6.39, 95% CI: 1.51-27.12) and severely impaired left ventricular function (HR = 4.04, 95% CI: 2.15-7.59) were the strongest predictors of mortality. Other factors tested (gender, hypertension, diabetes, hyperlipidaemia, established peripheral vascular disease/stroke, coronary arteries intervened, number of vessels treated, number of stents implanted and length of lesion treated) did not show any correlation with mortality. Conclusions The mortality of patients with CKD undergoing PCI increases with age, worsening CKD stage and deteriorating left ventricular systolic function, and it is also higher in patients with acute coronary syndromes compared to those with stable coronary artery disease.

    Abstract Both dexmedetomidine and sufentanil modulate spinal analgesia by different mechanisms, and yet no human studies are available on their combination for analgesia during the first 72 hours after abdominal hysterectomy. This CONSORT-prospective, randomized, double-blinded, controlled trial sought to evaluate the safety and efficacy of the combination of dexmedetomidine and sufentanil in intravenous patient-controlled analgesia (PCA) for 72 hours after abdominal hysterectomy. Ninety women undergoing total abdominal hysterectomy were divided into 3 equal groups that received sufentanil (Group C; 0.02 μg/kg/h), sufentanil plus dexmedetomidine (Group D1; 0.02 μg/kg/h, each), or sufentanil (0.02 μg/kg/h) plus dexmedetomidine (0.05 μg/kg/h) (Group D2) for 72 hours after surgery in this double-blinded, randomized study. The primary outcome measure was the postoperative sufentanil consumption, whereas the secondary outcome measures were pain intensity (visual analogue scale), requirement of narcotic drugs during the operation, level of sedation, Bruggrmann comfort scale, and concerning adverse effects. The postoperative sufentanil consumption was significantly lower in Groups D1 and D2 than in Group C during the observation period (P < 0.05), but lower in Group D2 than in Group D1 at 24, 48, and 72 hours after surgery (P < 0.05). The heart rate after intubation and incision was lower in Groups D1 and D2 than in Group C (P < 0.05). On arrival at the recovery room, Groups D1 and D2 had lower mean blood pressure than Group C (P < 0.05). The intraoperative requirement of sevoflurane was 30% lesser in Groups D1 and D2 than in Group C. The sedation levels were greater in Groups D1 and D2 during the first hour (P < 0.05). Compared with Groups C and D1, Group D2 showed lower levels of the overall incidence of nausea and vomiting (P < 0.05). Among the tested PCA options, the addition of dexmedetomidine (0.05 μg/kg/h) and sufentanil (0

    Panniculitis is a rare cutaneous manifestation of dermatomyositis (DM). The appearance of panniculitis during treatment with methotrexate (MTX) is exceptional and has only been described in 3 cases. We report a case of a 50-year-old woman suffering from DM since 1997 who was treated with corticosteroids showing favorable clinical and biological evolution. When a relapse occurred 2 years later, she was treated with higher-dose of corticosteroids in combination with a 7,5 mg weekly dose of methotrexate. The evolution was rapidly favorable. Eighteen months later, the patient had multiple subcutaneous nodules on limbs and buttocks. Anatomopathological examination showed panniculitis. There was no evidence supporting progression in DM. Prednisone dose was increased to 0.5 mg/kg/day, always in combination with MTX, without any clear signs of improvement. MTX treatment was stopped and the cutaneous lesions completely disappeared in 2 months without any relapse. This objective response lasted for 42 months. Our observation is particular given the occurrence of panniculitis in a patient undergoing treatment for dermatomyositis with methotrexate and illustrates the difficulties in the diagnosis. This entity must be known despite its exceptional nature since cutting off MTX treatment generally induces the disappearance of subcutaneous nodules. PMID:27279974

    Background The aim of the present study was to determine the safety and feasibility of the use of laryngeal mask airway (LMA) for non-endotracheal intubated anesthesia for patients with pectus excavatum (PE) undergoing thoracoscopic Nuss procedure. Methods Between July 2015 and December 2015, 30 selected patients with PE were planned to undergo a thoracoscopic Nuss procedure using LMA for non-endotracheal intubated anesthesia in the Guangdong General Hospital. The clinical data were analyzed to evaluate the safety and feasibility of this technique. Results Of the 30 selected patients, two were female, the mean age was 16.04±5.09 years and the average Haller index was 3.37±0.88. A total of 27 cases (90%) succeeded at the first attempt, one patient required conversion to an endotracheal tube (ETT) because of continuous air leak. The peripheral O2 saturation (SpO2), end-tidal carbon dioxide (EtCO2) values, heart rate (HR), and mean arterial blood pressure (MAP) remained stable throughout the procedure in all cases. All of the 30 patients were successfully corrected without requiring conversion to an open surgery. Two patients experienced postoperative nausea and one reported a sore throat. Neither gastro-esophageal reflux nor in-hospital mortality occurred. Conclusions The use of LMA for non-endotracheal intubated anesthesia for selected patients with PE undergoing thoracoscopic Nuss procedure is clinically safe and technically feasible. PMID:27621860

    Background Dysregulations of blood glucose (BG) are associated with adverse outcome in critical illness; controlling BG to target appears to improve outcome. Since BG-control is challenging in daily intensive care practice BG-control remains poor especially in patients with rapidly fluctuating BG. To improve BG-control and to avoid deleterious hypoglycemia, automated online-measurement tools are advocated. We thus evaluated the point-accuracy of the subcutaneous Sentrino® Continuous Glucose Monitoring System (CGM, Medtronic Diabetes, Northridge, California) in patients undergoing extracorporeal cardiac life support (ECLS) for cardiogenic shock. Methods Management of BG was performed according to institute’s standard aiming at BG-levels between 100–145 mg/dl. CGM-values were recorded without taking measures into therapeutic account. Point-accuracy in comparison to intermittent BG-measurement by the ABL-blood-gas analyzer was determined. Results CGM (n = 25 patients) correlated significantly with ABL-values (r = 0.733, p<0.001). Mean error from standard was 15.0 mg/dl (11.9%). 44.2% of the readings were outside a 15% range around ABL-values. In one of 635 paired data-points, ABL revealed hypoglycemia (BG 32 mg/dl) whereas CGM did not show hypoglycemic values (132mg/dl). Conclusions CGM reveals minimally invasive BG-values in critically ill adults with dynamically impaired tissue perfusion. Because of potential deviations from standard, CGM-readings must be interpreted with caution in specific ICU-populations. PMID:26963806

    Objectives: Removal of pro inflammatory stimuli after CABG, wound closure and the regenerative ability of the bone marrow will ensure a gradual recovery of hematological parameters. The aim of this study was to assess the hematological changes after CABG. Materials and Methods: A prospective cohort study included 164 consecutive patients undergoing on pump CABG surgery between January 2012 and January 2013. Patients with primary hematologic disease, emergent or urgent CABG and off-pump CABG were not included. A time line protocol was employed. Results: All patients survived surgery. Average values of erythrocytes, hemoglobin and hematocrit declined, to reach lower values on day 3 after surgery (-33.6 %, -33.1 %, -32.6 % versus preoperative value, p<0.001) and then gradually increased to reach normal values after one month and the preoperative values after three months. The average values of leukocytes and neutrophils increased rapidly to achieve the highest value on day 2, while the average value of lymphocytes decreased quickly to achieve lower value on day 1 after surgery (+74.7 %, +127.1 %, -52.4 % respectively from the preoperative value, p<0.001). The average platelet count decreased to the lowest value on day 2 after surgery (-26.4 % from the preoperative value, p<0.001), after which gradually increased up to +100.8 % of preoperative value on day 14 (p<0.001) and then gradually decreased to reach normal values on day 21 and preoperative values after three months. Conclusions: Average values of the three peripheral blood cells parameters undergo important changes after CABG, but not life threatening, and regain normal and preoperative values after 1-3 months after surgery.

    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.

  13. Pros and cons of splenectomy in patients with myelofibrosis undergoing stem cell transplantation.

    During fetal development, the spleen is a major hemopoietic organ. In the adult human, this task is relinquished to the bone marrow. However, under the stress of certain pathologic conditions, extramedullary hemopoiesis may again occur in the spleen. This is especially true for diseases of the marrow, in particular, myeloproliferative disorders such as agnogenic myeloid metaplasia, which is associated with severe fibrosis of the marrow space. At the same time, the spleen sequesters blood cells and contributes to peripheral blood cytopenias, which may improve following splenectomy. However, success is unpredictable, and the operative mortality of splenectomy is on the order of 10%. As a growing number of patients undergo hemopoietic stem cell transplantation as definitive therapy for myelofibrosis, the decision on splenectomy has additional ramifications since the spleen plays an important role in the kinetics of engraftment of donor cells and in immune reconstitution. We conclude from our analysis of available information that the benefit of splenectomy is difficult to predict, although after transplantation splenectomized patients have faster hemopoietic recovery. It appears that the most important indication for splenectomy in these patients is the relief of symptoms from massive spleen enlargement.

    The lack of consistent definitions and nomenclature across clinical trials of novel devices, drugs, or biologics poses a significant barrier to accrual of knowledge in and across peripheral artery disease therapies and technologies. Recognizing this problem, the Peripheral Academic Research Consortium, together with the U.S. Food and Drug Administration and the Japanese Pharmaceuticals and Medical Devices Agency, has developed a series of pragmatic consensus definitions for patients being treated for peripheral artery disease affecting the lower extremities. These consensus definitions include the clinical presentation, anatomic depiction, interventional outcomes, surrogate imaging and physiological follow-up, and clinical outcomes of patients with lower-extremity peripheral artery disease. Consistent application of these definitions in clinical trials evaluating novel revascularization technologies should result in more efficient regulatory evaluation and best practice guidelines to inform clinical decisions in patients with lower extremity peripheral artery disease.

    Obesity affects a disproportionate proportion of total knee arthroplasty (TKA) patients. Our study explores pre-operative characteristics between obese and non-obese patients undergoing TKA surgery. A cohort of 4718 osteoarthritic patients, undergoing primary TKA, was studied. Patients were stratified according to BMI classes. Each class was compared in terms of age, race, gender, level of education, insurance status, pre-operative WOMAC, SF-36, and Elixhauser comorbidities. There was a positive relationship between BMI and female gender, non-white race, Medicaid, private insurance, and self-pay. A negative relationship was observed between BMI and age, Medicare, WOMAC and SF-36. Obese TKA candidates differ from their non-obese counterparts in a number of demographic, socioeconomic, and clinical characteristics. PMID:23523207

    Despite the growing number of cancer cases and cancer surgeries around the world, the pharmacokinetics (PK) and pharmacodynamics (PD) of anesthetics used in this population are poorly understood. Patients operated due to cancer are usually in severe state and often require chemotherapy. It might affect the PK/PD of drugs used in this population. Therefore, in this study we explored the PK/PD of propofol in cancer patients having a major lung surgery. 23 patients that underwent a propofol-fentanyl total intravenous anesthesia were included in the analysis. A large set of demographic, biochemical and hemodynamic parameters was collected for the purpose of covariate analysis. Nonlinear mixed effect modeling in NONMEM was used to analyze the collected data. A three-compartment model was sufficient to describe PK of propofol. The anesthetic effect (AAI index) was linked to the propofol effect site concentrations through a sigmoidal E max model. A slightly higher value of clearance, a lower value of distribution clearance, and a decreased volume of peripheral compartment were observed in our patients, as compared with the literature values reported for healthy volunteers by Schnider et al. and by Eleveld et al. Despite these differences, both models led to a clinically insignificant bias of -8 and -1 % in concentration predictions, as reflected by the median performance error. The C e50 and propofol biophase concentration at the time of postoperative orientation were low and equaled 1.40 and 1.13 mg/L. The population PK/PD model was proposed for cancer patients undergoing a major lung surgery. The large body of studied covariates did not affect PK/PD of propofol significantly. The modification of propofol dosage in the group of patients under study is not necessary when TCI-guided administration of propofol by means of the Schnider model is used.

    Overwhelming infection causes significant morbidity and mortality among patients treated with bone marrow transplantation (BMT) for primary immune deficiencies, syndromes of bone marrow failure, or cancer. The polymorphonuclear leukocyte (PMN; neutrophil) is the first responder to microbial invasion and acts within the innate immune system to contain and clear infections. PMNs contain, and possibly clear, infections in part by forming neutrophil extracellular traps (NETs). NETs are extensive lattices of extracellular DNA and decondensed chromatin decorated with antimicrobial proteins and degradative enzymes, such as histones, myeloperoxidase, and neutrophil elastase. They trap and contain microbes, including bacteria and fungi, and may directly affect extracellular microbial killing. Whether or not deficient NET formation contributes to the increased risk for overwhelming infection in patients undergoing BMT remains incompletely characterized, especially in the pediatric population. We examined NET formation in vitro in PMNs isolated from 24 patients who had undergone BMT for 13 different clinical indications. For these 24 study participants, the median age was 7 years. For 6 of the 24 patients, we examined NET formation by PMNs isolated from serial, peripheral blood samples drawn at three different clinical time points: pre-BMT, pre-engraftment, and post-engraftment. We found decreased NET formation by PMNs isolated from patients prior to BMT and during the pre-engraftment and post-engraftment phases, with decreased NET formation compared with healthy control PMNs detected even out to 199 days after their BMT. This decrease in NET formation after BMT did not result from neutrophil developmental immaturity as we demonstrated that >80% of the PMNs tested using flow cytometry expressed both CD10 and CD16 as markers of terminal differentiation along the neutrophilic lineage. These pilot study results mandate further exploration regarding the mechanisms or factors

    Background Geriatric patients undergoing hemiarthroplasty for hip fractures have unacceptably high rates of postoperative complications and mortality. Whether anesthesia type can affect the outcomes has still been inconclusive. Objectives We compared general anesthesia (GA) and peripheral nerve blocks (PNBs) on postoperative complications and mortality in elderly patients with femoral neck fractures (FNF) undergoing hemiarthroplasty. Materials and methods This retrospective study involved data collection from an electronic database. Two hundred and seventeen patients underwent hemiarthroplasty for FNF between January 2008 and December 2012 at the Chinese People’s Liberation Army General Hospital. Data on mortality within in-hospital, 30-day, and 1-year, complications, comorbidities, blood loss and transfusion, operative time, postoperative hospital length of stay, intensive care unit admission, and hospital charge were collected and analyzed. Univariate and multivariate Cox regression analyses of all variables were used for 30-day and 1-year mortality. Results Seventy-two patients receiving GA and 145 receiving PNBs were eventually submitted and analyzed. Mortality was 6.9%, 14.7%, and 23.5% at in-hospital, 30-day, and 1-year, respectively postoperatively, while mortality and cardiovascular complications did not differ between the two anesthetic techniques. Preoperative comorbidities and intraoperative parameters were not statistically different except that patients receiving GA were more likely to have dementia (χ2=10.45, P=0.001). The most common complications were acute cardiovascular events, electrolyte disturbances, and delirium. Postoperative acute respiratory events and hypoxemia both were also common, but no differences were found between groups (χ2=0.68, P=0.410; χ2=3.42, P=0.065, respectively). Key factors negatively influencing mortality included: age, male gender, American Society of Anesthesiologists status, dementia, perioperative cardiovascular

    ABSTRACT Purpose: To identify the educational needs of adults who undergo total hip and total knee replacement surgery. Methods: A qualitative research design using a semi-standardized interviewing method was employed. A purposive sampling technique was used to recruit participants, who were eligible if they were scheduled to undergo total hip or total knee replacement or had undergone total hip or total knee replacement in the previous 3 to 6 months. A comparative contrast method of analysis was used. Results: Of 22 potential participants who were approached, 15 participated. Five were booked for upcoming total hip or total knee replacement and 10 had undergone at least one total hip or total knee replacement in the previous 3 to 6 months. Several themes related to specific educational needs and factors affecting educational needs, including access, preoperative phase, surgery and medical recovery, rehabilitation process and functional recovery, fears, and expectations counterbalanced with responsibility, emerged from the interviews. Conclusions: Educational needs of adults who undergo total hip and knee replacement surgery encompass a broad range of topics, confirming the importance of offering an all-inclusive information package regarding total hip and total knee replacement.

    Available propofol pharmacokinetic protocols for target-controlled infusion (TCI) were obtained from healthy individuals. However, the disposition as well as the response to a given drug may be altered in clinical conditions. The aim of the study was to examine population pharmacokinetics (PK) and pharmacodynamics (PD) of propofol during total intravenous anesthesia (propofol/fentanyl) monitored by bispectral index (BIS) in patients scheduled for abdominal aortic surgery. Population nonlinear mixed-effect modeling was done with Nonmem. Data were obtained from ten male patients. The TCI system (Diprifusor) was used to administer propofol. The BIS index served to monitor the depth of anesthesia. The propofol dosing was adjusted to keep BIS level between 40 and 60. A two-compartment model was used to describe propofol PK. The typical values of the central and peripheral volume of distribution, and the metabolic and inter-compartmental clearance were V(C) = 24.7 l, V(T) = 112 l, Cl = 2.64 l/min and Q = 0.989 l/min. Delay of the anesthetic effect, with respect to plasma concentrations, was described by the effect compartment with the rate constant for the distribution to the effector compartment equal to 0.240 min(-1). The BIS index was linked to the effect site concentrations through a sigmoidal E(max) model with EC(50) = 2.19 mg/l. The body weight, age, blood pressure and gender were not identified as statistically significant covariates for all PK/PD parameters. The population PK/PD model was successfully developed to describe the time course and variability of propofol concentration and BIS index in patients undergoing surgery.

    There has been an increase in the number of patients undergoing lung resection for primary or suspected primary lung cancer in the UK due to improved staging techniques, dedicated thoracic surgeons and other initiatives such as preoperative pulmonary rehabilitation. This has had an impact on local healthcare resources requiring new ways of delivering thoracic surgical services. When considering service changes, patient reported outcomes are pivotal in terms of ensuring that the experience of care is enhanced and may include elements such as involving patients in their care, reducing the length of inpatient stay and reducing postoperative complications. The implementation of a thoracic surgical Patient Education Programme (PEP) has the potential to address these measures and improve the psychological and physical wellbeing of patients who require a lung resection. It may also assist in their care as an inpatient and to enhance recovery after surgery both in the short and long term. PMID:25984358

    OBJECT Vertebral fractures are the most common osteoporotic fracture. Bone density testing and medical treatment with bisphosphonates or parathormone are recommended for all patients with an osteoporotic fracture diagnosis. Inadequate testing and treatment of patients presenting with low-impact fractures have been reported in various specialties. Similar data are not available from academic neurosurgery groups. The authors assessed compliance with treatment and testing of osteoporosis in patients with vertebral compression fractures evaluated by the authors' academic neurosurgery service, and patient variable and health-systems factors associated with improved compliance. METHODS Data for patients who underwent percutaneous kyphoplasty for compression fractures was retrospectively collected. Diagnostic and medical interventions were tabulated. Pre-, intra-, and posthospital factors that had been theorized to affect the compliance of patients with osteoporosis-related therapies were tabulated and statistically analyzed. RESULTS Less than 50% of patients with kyphoplasty received such therapies. Age was not found to correlate with other variables. Referral from a specialist rather than a primary care physician was associated with a higher rate of bone density screening, as well as vitamin D and calcium therapy, but not bisphosphonate/parathormone therapy. Patients who underwent preoperative evaluation by their primary care physician were significantly more likely to receive bisphosphonates compared with those only evaluated by a hospitalist. Patients with unprovoked fractures were more likely to undergo multiple surgeries compared with those with minor trauma. CONCLUSIONS These results suggest poor compliance with current standard of care for medical therapies in patients with osteoporotic compression fractures undergoing kyphoplasty under the care of an academic neurosurgery service.

    Purpose Opioid-based intravenous patient-controlled analgesia (IV-PCA) is a popular method of postoperative analgesia, but many patients suffer from PCA-related complications. We hypothesized that PCA was not essential in patients undergoing major abdominal surgery by minimal invasive approach. Methods Between February 2013 and August 2013, 297 patients undergoing laparoscopic surgery for colorectal cancer were included in this retrospective comparative study. The PCA group received conventional opioid-based PCA postoperatively, and the non-PCA group received intravenous anti-inflammatory drugs (Tramadol) as necessary. Patients reported their postoperative pain using a subjective visual analogue scale (VAS). The PCA-related adverse effects and frequency of rescue analgesia were evaluated, and the recovery rates were measured. Results Patients in the PCA group experienced less postoperative pain on days 4 and 5 after surgery than those in the non-PCA group (mean [SD] VAS: day 4, 6.2 [0.3] vs. 7.0 [0.3], P = 0.010; and day 5, 5.1 [0.2] vs. 5.5 [0.2], P = 0.030, respectively). Fewer patients in the non-PCA group required additional parenteral analgesia (41 of 93 patients vs. 53 of 75 patients, respectively), and none in the non-PCA group required rescue PCA postoperatively. The incidence of postoperative nausea and vomiting was significantly higher in the non-PCA group than in the PCA group (P < 0.001). The mean (range) length of hospital stay was shorter in the non-PCA group (7.9 [6-10] days vs. 8.7 [7-16] days, respectively, P = 0.03). Conclusion Our Results suggest that IV-PCA may not be necessary in selected patients those who underwent minimal invasive surgery for colorectal cancer. PMID:25692119

    Unexpected fatal events in patients with head and neck cancers undergoing concurrent chemoradiation therapy are a clinical concern. Malnutrition, which is reported frequently in head and neck cancer patients, are associated with immunity derangement. The purpose of this study was to identify risk factors for early death of patients undergoing chemoradiation. We retrospectively analyzed the records of 194 stage III, IVA, and IVB head and neck cancer patients who were treated with chemoradiation between 2007 and 2009. We defined early death as death while receiving chemoradiation or within 60 days of treatment completion. Risk factors for early death were tested using univariate and multivariate analyses. Fourteen patients (7.2 %) experienced early death, 78.6 % of whom died of infection. Univariate analysis revealed significant correlations between early death and several pretreatment variables, including Eastern Cooperative Oncology Group performance status (PS) >1, hemoglobin <10 g/dL, albumin <3 g/dL, body mass index (BMI) <19 kg/m(2), and peripheral blood total lymphocyte count <700/μL. Multivariate analysis showed that PS >1, BMI <19 kg/m(2), and peripheral blood total lymphocyte count <700/μL were independent variables associated with early death. Poor performance status and malnutrition before chemoradiation independently predict early death in locally advanced head and neck cancer patients undergoing chemoradiation. Cautious management of head and neck cancer patients with these risk factors is required throughout chemoradiation period.

    Peripheral facial nerve palsy (FNP) is a mononeuropathy that affects the peripheral part of the facial nerve. Primary causes of peripheral FNP remain largely unknown, but detectable causes include systemic infections (viral and others), trauma, ischemia, tumor, and extrinsic compression. Peripheral FNP in relation to extrinsic compression has rarely been described in case reports. Here, we report a case of a 71-year-old man who was diagnosed with peripheral FNP following endoscopic submucosal dissection. This case is the first report of the development of peripheral FNP in a patient undergoing therapeutic endoscopy. We emphasize the fact that physicians should be attentive to the development of peripheral FNP following therapeutic endoscopy.

    Currently, no molecular biological markers do exist for early diagnosis of breast cancer. One of the possible candidates for the marker of early breast cancer is mammaglobin (MGB1) or SCGB2A2 (secretoglobin, family 2A, member 2), characterized by the maximal expression level in early breast cancer. Using the RT-PCR method MGB1 mRNA expression was examined in 57 tumor tissue samples and 57 samples of morphologically non-malignant tissue (MNT) of breast cancer (BC) patients. Specificity and sensitivity of the MGB1 mRNA assay in peripheral blood of BC patients was evaluated by nested PCR. 169 blood samples (from 95 BC patients, 22 from patients with benign breast tumors, 28 from patients with tumors of other localizations, and 24 samples from healthy donors) have been analyzed. MGB1 expression was significantly higher in BC tissue samples compared to MNT (p=0.0019). The maximal expression level was in the samples T1 (p=0.013), stage I BC (p=0.037), GI (p=0.0019). The MGB1 expression positively correlated with expression of estrogen (p = 0,034) and progesterone (p=0.0004) receptors. Sensitivity and specificity of the MGB1 mRNA assay in peripheral blood were 60.6% and 92.3%, respectively. Expression of MGB1 was higher in BC than MNT and it decreased during BC progression. The sensitivity and specificity of the MGB1 mRNA assay may be used as an additional diagnostic method. PMID:27563000

    A valid control group is an essential part of any patient study. We asked whether burned children returning for reconstructive surgery could be used as "controls" in a study of seven proteolytic elements in the circulation. Functional levels of elastase, plasminogen, prekallikrein, antithrombin, alpha 2-antiplasmin, alpha 2-macroglobulin, and total proteolytic activity in 30 healthy unburned children were compared with levels in 29 patients admitted for reconstructive surgery an average of 7.9 years after burn. The two groups were not statistically different in distributions of sex and race but differed in mean age. Levels of six of the seven parameters were equal in the two groups. However, even when correction for the age difference was done between the groups, alpha 2-macroglobulin in the patients undergoing reconstructive surgery still was significantly less (p < 0.021) than in the unburned group. Therefore caution may be needed when readily available patients undergoing reconstructive surgery are used as "controls" in studies of patients with acute burns.

    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

    Peripheral arterial disease (PAD) describes the clinical manifestations of atherosclerosis affecting the circulation in the legs. The severity of PAD is classified according to symptom severity, time course, and anatomical distribution. The signs and symptoms of PAD reflect the degree of circulatory compromise and whether there has been a gradual reduction in the circulation or an abrupt, uncompensated decrease. Accurate clinical assessment underpins decisions on management strategy and should objectively assess the severity of the ischemia and need for revascularization. Clinical history should discriminate symptoms of PAD from other conditions presenting with leg pain, elucidate cardiovascular risk factors and the effect of symptoms on the patient's quality of life. Clinical examination includes signs of general cardiovascular disease and associated conditions before assessing the circulation and viability of the limb. Palpation of peripheral pulses must be augmented by determination of the ankle brachial pressure index using hand held Doppler. A whole patient approach to management is required and must include modification of cardiovascular risk status as well as dealing with the local circulatory manifestation of PAD. PMID:25435653

    Venous access devices are of pivotal importance for an increasing number of critically ill patients in a variety of disease states and in a variety of clinical settings (emergency, intensive care, surgery) and for different purposes (fluids or drugs infusions, parenteral nutrition, antibiotic therapy, hemodynamic monitoring, procedures of dialysis/apheresis). However, healthcare professionals are commonly worried about the possible consequences that may result using a central venous access device (CVAD) (mainly, bloodstream infections and thrombosis), both peripherally inserted central catheters (PICCs) and centrally inserted central catheters (CICCs). This review aims to discuss indications, insertion techniques, and care of PICCs in critically ill patients. PICCs have many advantages over standard CICCs. First of all, their insertion is easy and safe -due to their placement into peripheral veins of the arm- and the advantage of a central location of catheter tip suitable for all osmolarity and pH solutions. Using the ultrasound-guidance for the PICC insertion, the risk of hemothorax and pneumothorax can be avoided, as well as the possibility of primary malposition is very low. PICC placement is also appropriate to avoid post-procedural hemorrhage in patients with an abnormal coagulative state who need a CVAD. Some limits previously ascribed to PICCs (i.e., low flow rates, difficult central venous pressure monitoring, lack of safety for radio-diagnostic procedures, single-lumen) have delayed their start up in the intensive care units as common practice. Though, the recent development of power-injectable PICCs overcomes these technical limitations and PICCs have started to spread in critical care settings. Two important take-home messages may be drawn from this review. First, the incidence of complications varies depending on venous accesses and healthcare professionals should be aware of the different clinical performance as well as of the different risks

    Aortic augmentation index (AIx) is used to investigate arterial stiffness. The authors tested the hypothesis that patients with peripheral arterial disease (PAD) demonstrate a higher AIx and also evaluated several related factors. In 97 patients with PAD, identified by ankle-brachial pressure index (ABPI ≤ 0.9), and 97 controls (ABPI ≥ 0.91< 1.4), AIx (%) was determined using tonometry of the radial artery. There was no significant difference between patients and controls in characteristics of age, sex, height, diastolic blood pressure, mean blood pressure, and heart rate. AIx was higher in patients with PAD (32 ± 9 vs 28 ± 9; P = .001). In multivariate regression analysis, AIx was independently associated with heart rate (β = -0.40, P = .0005). This study showed that AIx increased in patients with PAD and that heart rate is a determinant of AIx. Further studies are necessary to assess the pathophysiological and clinical importance of AIx in patients with PAD. PMID:25228305

    Positioning injuries in the perioperative period are one of the inherent risks of surgery, but particularly in robot-assisted urologic surgery, and can result in often unrecognized morbidity. Injuries such as upper or lower extremity peripheral neuropathies occur via neural mechanisms and injuries such as compartment syndrome, rhabdomyolysis, ischemic optic neuropathy, and acute arterial occlusion occur via vascular mechanisms. The risk of injury may be exacerbated by operative and patient-related risk factors. Patient-related risk factors include ASA class and BMI, while surgery-related risk factors include physical orientation of the patient and operative length. These injuries can be prevented or reduced by joint effort of the surgeon, anesthesiologist, and operating room staff.

    Case Description A 60-year-old man developed painless neutropenic enterocolitis after induction chemotherapy for newly diagnosed acute myelogenous leukemia. The patient had recurrent fever while neutropenic, without experiencing abdominal pain or tenderness on physical examination. His diagnosis was delayed by the fact that he had no localizing symptoms. Discussion Neutropenic enterocolitis is a common complication, generally occurring in patients who are severely neutropenic; the condition presents with fever and abdominal pain. No cases of painless neutropenic enterocolitis have yet been reported. Review of the literature shows that patients can develop this condition in the absence of fever and, sometimes, neutropenia. Furthermore, few comprehensive studies or reviews have investigated the utility of computed tomography imaging in identifying a source for abdominal pain in neutropenic patients with fever. Summary Many potential causes of febrile neutropenia should be considered in chemotherapy patients. PMID:27803612

    Percutaneous coronary intervention (PCI) is a common procedure to treat coronary artery stenoses. Several studies had demonstrated that PCI does not reduce the risk of death or myocardial infarction when performed to patients with stable angina. However it has been observed that most patients believe that PCI will reduce their risk for death and myocardial infarction. On the other hand, cardiologists generally acknowledge the limitation of PCI according to the current literature.Cardiologists' decision to refer a patient to PCI is based on factors other then perceived benefits such as fear of missing a needed procedure, defensive medicine, desire of demonstrating their professional competence, vested professional and economic interests, accomplish patient expectation, the so called oculo-stenotic reflex, when a lesion is dilated regardless the clinical indication. Patients' misleading perception of harm and benefits of a procedure is mainly related to the cognitive dissonance, when individuals tend to reduce the conflict of an uncomfortable decision adopting information, which are likely to reduce their discomfort. Furthermore, patients believe that doing more means doing better, that technologic intervention are better than pharmacological treatment that in turn are better than doing nothing. Finally, they assume that a procedure is really effective since their physician suggested it.It should be emphasized that physicians and patients do not communicate successfully about key decision and how little we know about patient understanding of the factors that influence important medical care decisions. Although considerable attention is given to facilitating informed consent, patients' perceived benefits of elective PCI do not match existing evidence, as they overestimated both the benefits and urgency of their procedures. These findings suggest that an even greater effort at patient education is needed prior to elective PCI to facilitate fully informed decision-making.

    ♦ Background: Peritonitis is the leading cause of morbidity for peritoneal dialysis (PD) patients, and microbial biofilms have previously been identified on catheters from infected patients. However, few studies of catheters from patients without clinical signs of infection have been undertaken. The aim of the present study was to investigate the extent to which bacteria are present on catheters from PD patients with no symptoms of infection. ♦ Methods: Microbiologic culturing under aerobic and anaerobic conditions and confocal laser scanning microscopy were used to determine the distribution of bacteria on PD catheters from 15 patients without clinical signs of infection and on catheters from 2 infected patients. The 16S rRNA gene sequencing technique was used to identify cultured bacteria. ♦ Results: Bacteria were detected on 12 of the 15 catheters from patients without signs of infection and on the 2 catheters from infected patients. Single-species and mixed-microbial communities containing up to 5 species were present on both the inside and the outside along the whole length of the colonized catheters. The bacterial species most commonly found were the skin commensals Staphylococcus epidermidis and Propionibacterium acnes, followed by S. warneri and S. lugdunensis. The strains of these micro-organisms, particularly those of S. epidermidis, varied in phenotype with respect to their tolerance of the major classes of antibiotics. ♦ Conclusions: Bacteria were common on catheters from patients without symptoms of infection. Up to 4 different bacterial species were found in close association and may represent a risk factor for the future development of peritonitis in patients hosting such micro-organisms. PMID:22855889

    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.

Factor analysis indicated that therapy-related expectations come into three broad categories--pain/emotional control, healing and tumour/symptom control. 35 patients expected 'healing' even though curative treatment was intended in only 19 and all patients had been fully informed. The expectation of healing was associated with high quality of life, and the same was true of perception of healing after radiotherapy. In the group as a whole, quality of life was little altered by radiotherapy, but it became substantially worse in those patients who had expected healing but perceived that this had failed, even though physician-assessed Karnofsky status did not change. These findings indicate that the expectation of healing, in cancer patients, is a component of a good global quality of life, whereas more limited expectations (pain control, tumour control) relate to lower quality of life. Patients' expectations deserve further study as a novel approach to improving care. PMID:11193059

    Renovascular disease (RVD) can lead to hypertension and chronic kidney disease (CKD). Patients with advanced peripheral arterial disease (PAD) have a 5-year mortality of ∼30%. Rate and causes of death in patients with significant RVD, who share similar risk factors with patients having PAD, are not well defined. We assessed consecutive patients with RVD who underwent renal artery stenting at our institution over 6 years. Specific causes of death were ascertained, and the probability of survival was estimated. Cox models were fit to identify predictors of outcomes. We identified 281 patients with RVD who underwent renal stenting. Follow-up was available for all patients (median 5.1 years). All-cause mortality was 24.2% at 5 years and 33.7% at 7 years (compounded annualized death rate: 5.5%). Of the 68 deaths, 36 (52.9%) were cardiovascular (13.2% acute myocardial infarction, 13.2% stroke, 11.8% sudden death, and 10.3% congestive heart failure) and 32 (47.1%) deaths had noncardiovascular causes. In patients with RVD undergoing stenting, cardiovascular events are the most common causes of death. Compared to patients with advanced PAD, RVD may have a lower 5-year mortality.

    This study aims to determine the prevalence, types, and associated factors for the use of herbal remedies in hemodialysis patients. Two hundred participants were selected by stratified sampling and were systematically interviewed. One hundred and twenty-six patients (63%) had used herbal remedies some time since their initiation of dialysis treatment. The users of herbal remedies had a significantly older age than nonusers, but no other significant differences were observed. The most prevalent complaints that led to herbal remedies use were gastroenterological complaints, flushing, and excessive thirst. Cichorium intybus, Borage officinalis, Mentha longifolia, and Matricaria recutita were the most prevalently used herbs in our patients. More study should be done on safety and efficacy of these herbs for hemodialysis patients. PMID:24241097

    Discharge destination to skilled nursing facilities (SNF) following total joint arthroplasty (TJA) plays an important role in healthcare costs. The pre-operative, intra-operative, and post-operative factors of 50 consecutive patients discharged to an SNF following TJA were compared to that of 50 consecutive patients discharged to home. Patients discharged to SNFs had slower pre-operative Get Up and Go scores (TGUG), lower pre-operative EQ-5D scores, higher ASA scores, increased hospital length of stay, increased self-reported post-operative pain, and decreased physical therapy achievements. We believe that the results of this study indicate that patients who get discharged to SNFs fit a certain criteria and this may be used to guide post-operative discharge destination during pre-operative planning, which can help lower costs while helping decrease the length of inpatient stay.

    Background Sudden cardiac death is one of the primary causes of mortality in chronic hemodialysis (HD) patients. Prolonged QTc interval is associated with increased rate of sudden cardiac death. The aim of this article is to assess the abnormalities found in electrocardiograms (ECGs), and to explore factors that can influence the QTc interval. Methods A total of 141 conventional HD patients were enrolled in this study. ECG tests were conducted on each patient before a single dialysis session and 15 minutes before the end of dialysis session (at peak stress). Echocardiography tests were conducted before dialysis session began. Blood samples were drawn by phlebotomy immediately before and after the dialysis session. Results Before dialysis, 93.62% of the patients were in sinus rhythm, and approximately 65% of the patients showed a prolonged QTc interval (i.e., a QTc interval above 440 ms in males and above 460ms in females). A comparison of ECG parameters before dialysis and at peak stress showed increases in heart rate (77.45±11.92 vs. 80.38±14.65 bpm, p = 0.001) and QTc interval (460.05±24.53 ms vs. 470.93±24.92 ms, p<0.001). After dividing patients into two groups according to the QTc interval, lower pre-dialysis serum concentrations of potassium (K+), calcium (Ca2+), phosphorus, calcium* phosphorus (Ca*P), and higher concentrations of plasma brain natriuretic peptide (BNP) were found in the group with prolonged QTc intervals. Patients in this group also had a larger left atrial diameter (LAD) and a thicker interventricular septum, and they tended to be older than patients in the other group. Then patients were divided into two groups according to ΔQTc (ΔQTc = QTc peak-stress- QTc pre-HD). When analyzing the patients whose QTc intervals were longer at peak stress than before HD, we found that they had higher concentrations of Ca2+ and P5+ and lower concentrations of K+, ferritin, UA, and BNP. They were also more likely to be female. In addition, more cardiac

    Endovascular aneurysm repair has taken over open surgery as the primary strategy for treatment of patients with abdominal and thoracic aneurysms. The minimally invasive nature of these techniques requires alterations in preoperative workup, intraoperative management, and familiarity with unique complications that can occur. Familiarity from the anesthetic standpoint of endovascular techniques, including treatment of patients with fenestrated, chimney, snorkel, and periscope grafts, is necessary for the contemporary cardiac anesthesiologist.

    Introduction. It is a consensus that the postoperative cognitive function is impaired in elderly patients after general anaesthesia, and such category patient takes more time to recover. Xenon is a noble gas with anesthetic properties mediated by antagonism of N-methyl-D-aspartate receptors. With a minimum alveolar concentration of 0.63, xenon is intended for maintaining hypnosis with 30% oxygen. The fast recovery after xenon anaesthesia was hypothesized to be advantageous in this scenario. Case Presentation. We report the case of 99-year-old woman who underwent sigmoid colon carcinoma resection with colorectal anastomosis. We carried out the induction phase by propofol, oxygen, fentanil, and rocuronium bromide, and then we proceeded to a rapid sequence endotracheal intubation consequently. The patient was monitored by IBP, NIBP, ECG, cardiac frequency, respiratory rate, capnometry, TOF Guard, blood gas analysis, and BIS. For maintenance we administrated oxygen, remifentanil, rocuronium bromide, and xenon gas 60–65%. Shortly after the end of surgery the patients started an autonomous respiratory activity, and a high BIS level was also recorded. Decision was made by our team to proceed into the emergence phase. The residual neuromuscular block was antagonized by sugammadex, modified Aldrete score was implicated, and we got our patient fully awake without any cognitive dysfunction or delirium. Conclusion. The rapid emergence to full orientation in very elderly patient who had been anesthetized by xenon shows concordance to the high BIS values and the clinical signs of the depth of anesthesia.

    AIM: To investigate the effect of prophylaxis with antibiotics on clinical adverse events in patients who underwent endoscopic submucosal dissection (ESD) or endoscopic mucosal resection (EMR) for colorectal lesions. METHODS: From June 2011 to December 2013, a total of 428 patients were enrolled into the study, of which 214 patients admitted to hospital underwent EMR or ESD procedures. These patients were randomized to an antibiotic group, in which patients were given cefuroxime 1.5 g iv half an hour before and 6 h after surgery respectively, and a control group, in which patients were not given any antibiotic. A further 214 outpatients with small polyps treated by polypectomy were compared with controls that were matched by age and gender, and operations were performed as outpatient surgery. Recorded patient parameters were demographics, characteristics of lesions and treatment modality, and the size of the wound area. The primary outcome measures were clinical adverse events, including abdominal pain, diarrhea, hemotachezia, and fever. Secondary outcome measures were white blood cell count, C-reactive protein and blood culture. Additionlly, the relationship between the size of the wound area and clinical adverse events was analyzed. RESULTS: A total of 409 patients were enrolled in this study, with 107 patients in the control group, 107 patients in the antibiotic group, and another 195 cases in the follow-up outpatient group. The patients’ demographic characteristics, including age, gender, characteristics of lesions, treatment modality, and the size of the wound area were similar between the 2 groups. The rates of adverse events in the antibiotic group were significantly lower than in the control group: abdominal pain (2.8% vs 14.9%, P < 0.01), diarrhea (2.0% vs 9.3%, P < 0.05), and fever (0.9% vs 8.4%, P < 0.05) respectively. The levels of inflammatory markers also decreased significantly in the antibiotic group compared with the control group: leukocytosis

    To investigate the appropriateness of the current vancomycin dosing strategy in adult patients with extracorporeal membrane oxygenation (ECMO), between March 2013 and November 2013, patients who were treated with vancomycin while on ECMO were enrolled. Control group consisted of 60 patients on vancomycin without ECMO, stayed in medical intensive care unit during the same study period and with the same exclusion criteria. Early trough levels were obtained within the fourth dosing, and maintenance levels were measured at steady state. A total of 20 patients were included in the analysis in ECMO group. Sixteen patients received an initial intravenous dose of 1.0 g vancomycin followed by 1.0 g every 12 hours. The non-steady state trough level of vancomycin after starting administration was subtherapeutic in 19 patients (95.00%) in ECMO group as compared with 40 patients (66.67%) in the control group (p = 0.013). Vancomycin clearance was 1.27±0.51 mL/min/kg, vancomycin clearance/creatinine clearance ratio was 0.90 ± 0.37, and elimination rate constant was 0.12 ± 0.04 h-1. Vancomycin dosingfrequency and total daily dose were significantly increased after clinical pharmacokinetic services of the pharmacist based on calculated pharmacokinetic parameters (from 2.10 ± 0.72 to 2.90 ± 0.97 times/day, p = 0.002 and from 32.54 ± 8.43 to 42.24 ± 14.62mg/kg, p = 0.014) in ECMO group in contrast with those (from 2.11 ± 0.69 to 2.37 ± 0.86 times/day, p = 0.071 and from 33.91 ± 11.85 to 31.61 ± 17.50 mg/kg, p = 0.350) in the control group.Although the elimination rate for vancomycin was similar with population parameter of non ECMO patients, the current dosing strategy of our institution for vancomycinin our ICU was not sufficient to achieve the target trough in the initial period in most patients receiving ECMO.

    2 334 patients from 29 dental practices took part in a written survey on their experiences with dental treatment in general as well as treatment of periodontal disease (response rate 80.8%). 72.6% of all participating patients fully agreed that they could recommend their dentist to their friends. 63.6% of patients undergoing treatment of periodontitis (N=328) rated this treatment as "excellent". However, for important aspects (prevention, patient information, treatment) potentials for improvement became obvious. 43.7% of patients treated for periodontitis were not completely satisfied with information on how this disease develops; 40.7% saw potentials for better information on preventive care (dental-hygiene, nutrition). An even higher percentage of patients actually not treated for periodontitis was interested in more information on prevention (51.4%). The results of the survey show that dentists should offer information and exercise on how to prevent periodontal desease more actively. There is a lack of research on the present state of affairs and potentials for improvement concerning treatment and prevention of periodontitis including the patients' perspective. PMID:26086539

    This study aimed to explore needs and expectations of Iranian patients who undergone angioplasty procedures. Coronary artery disease is the leading cause of morbidity and mortality worldwide. Recently, Percutaneous Coronary Intervention (PCI) has frequently been used as a substitute for coronary artery surgery, representing a less invasive and more cost-effective procedure. However, little information is known about the experiences and needs of patients undergone PCI. This research involved a qualitative study that employed the content analysis method. A semi-structured in-depth interview protocol was carried out using a face-to-face approach. Researchers reached to theoretical saturation by interviewing 18 patients who undergone angioplasty. Constant comparison analysis was used with simultaneous data collection. Three themes emerged from this study including Uncertainty, Procedural knowledge and Social Support. The findings from this study enhance our understanding on expectations and needs of patients who undergone PCI. These findings help nurses and health-care providers to develop and provide pre and post-procedural care according to each individual needs and experiences. This Iranian study not only contributes to other international study but also, emphasizes on the need for pre-procedural awareness and post-procedural support of patients who undergone PCI.

    The Peripherally Inserted Central Catheter (PICC) is still in its infancy in Taiwan. It has many advantages, including safety, simplicity, and few complications during the insertion process. It is suitable for patients who need long-term parenteral administration of medication or chemotherapy. However, the duration of PICC implantation is around six months, or even up to one year. As a result, it is very important to educate patients to take care of themselves throughout the implantation period in order to prevent complications. This report describes the experience of nursing a forty-four-year old male patient who suffered from acute lymphocytic leukemia and received a PICC implantation while undergoing chemotherapy treatment. As a PICC case manager, the author utilized self-efficacy theory and devoted herself to nursing care, interviews and phone calls to collect valuable information. During the process of PICC implantation, the author analyzed the characteristics of this case and assisted the patient and his primary care giver in choosing a suitable catheter and self-care techniques to achieve minimal complications during implantation. It is hoped that, by sharing in her experience, nursing staff may enhance their ability to assist patients with PICC and to help them to maintain their quality of life.

    A prospective evaluation of vocal changes in patients receiving radiation therapy for T1 and T2 (AJC) glottic carcinoma was undertaken in January 1987. Vocal analysis was performed prior to radiotherapy and at specific intervals throughout the radiation treatment program. The voicing ratio was extrapolated from a sustained vowel phonation using the Visipitch interfaced with the IBM-PC. Preliminary observations suggested three distinct patterns of vocal behavior: 1. reduced voicing ratio with precipitous improvement within the course of treatment, 2. high initial voicing ratio with reduction secondary to radiation induced edema, with rapid improvement in the voicing component after the edema subsided, and 3. fluctuating voicing ratio during and following treatment. Enrollment of new patients and a 2-year follow-up of current patients was undertaken. PMID:2348739

    Iron deficiency in patients with morbid obesity can occur before bariatric surgery due to its inflammatory component and after surgery as the result of implementing the malabsorptive techniques. For patients with morbid obesity, micronutrient deficiencies, such as vitamin B12, iron and folate, should be suspected. Iron deficiency and other hematinics should be corrected, even when anemia has not been established. Normal ferritin levels do not allow us to rule out a possible iron deficiency, given that ferritin can increase due to the chronic inflammatory condition of obesity. After bariatric surgery, patients should take iron supplements; however, these supplements are frequently poorly tolerated. Rapid and effective correction of hemoglobin levels might require the intravenous administration of iron preparations.

    The Patient Advocacy Committee of the International Federation of Kidney Foundations (IFKF) has developed a document proposing a set of rights for individuals with end stage renal failure (ESRF). These rights have been approved by the Board of Directors of the IFKF. Twenty rights have been developed and are organized into the following categories: (i) need of treatment and choice of patients; (ii) treatment of ESRF by haemodialysis; (iii) treatment of ESRF by peritoneal dialysis; and (iv) renal transplantation. It is the hope of this Committee and the IFKF that this document will provide a stimulus to more scientific inquiry and discussion as to what rights do patients possess with regard to treatment of chronic kidney disease, regardless of where they live or what may be their economic, social, ethnic or political status.

    Introduction To obtain the optimal anesthesia depth is not easy in cardiovascular surgery patients where the haemodynamic reserve is limited, due to reasons such as not being able to give the desired dose of anesthetic agent, or the change in the pharmacokinetics of the agent in the heart-lung machine. This study was planned to assess the contribution of bispectral index (BIS) monitoring in the depth of anesthesia. Methods The patients were divided into 2 groups, and BIS monitoring was used for each patient. Group 1 (G1 n=35): keeping the BIS monitor screen open, the anesthesia need was set. Group 2 (G2 n=35): BIS monitor was tied to the patient and the monitor screen was closed in such a way that the anaesthesist couldn't see the BIS value. When the recording time came, the data on the monitor was recorded. The need for the anesthetic agent was set according to the parameters such as haemodynamics or follow up of pupils, instead of BIS value, by titrating the anesthetic infusion doses. Results BIS values were similar in both groups before the induction, BIS values in both groups showed a decrease, showing no significant statistical difference (P>0.05). One patient in each group said that he dreamt, and one patient in G2 said that he had heard a noise and felt that he was taken from one place to another. Conclusion The management should be done with clinical evaluation, haemodynamics and other monitorization methods and BIS monitoring findings together. PMID:27556320

    Extracorporeal membrane oxygenation (ECMO) for cardiovascular collapse or catastrophic respiratory failure in the critically ill patient imposes a multidisciplinary approach. Nutritional support is one of the issues that must be faced, as this population presents a state of increased metabolic activity, elevated catabolism of protein and rapid accumulating energy deficiency. Provision of adequate nutritional therapy is hard to achieve due to different factors. This article provides a brief overview of the current literature regarding nutritional support during ECMO in adult patients, as no current guidelines address this issue.

    Infection with hepatitis C virus (HCV) is increasing all over the world, especially among hemodialysis patients. HCV is one of the major autoantibody inducing viruses, where anti-nuclear antibodies (ANA), anti-smooth muscle antibodies (ASMA), anti-liver kidney microsome antibodies (LKM-1), and rheumatoid factor (RF) have been related to HCV. Few studies have investigated the presence of anti-extractable nuclear antigens (ENA) antibodies in chronic liver diseases, especially in chronic hepatitis C cases, but none investigated its immunostimulation role in hemodialysis units. The aim of the study was to assess the prevalence of HCV among chronic kidney disease- Stage 5 (CKD5) patients undergoing hemodialysis and the prevalence of ENA antibodies among them. Sera of 134 patients with chronic kidney disease undergoing hemodialysis, were screened for HCV antibodies and ENA antibodies profile, using ELISA and Immunoblot technique. 41 HCV-positive blood bank donors were used as controls. Sixty-four (47.7%) of 134 patients undergoing hemodialysis were infected with HCV. Thirty-three (51.6%) of 64 patients with HCV infection undergoing hemodialysis had anti-ENA antibodies: 9 (27.3%) showed anti-SSA antibodies and 22 (66.7%) had anti-SSB antibodies. The prevalence of anti-ENA antibodies was significantly higher in the patients with HCV infection, undergoing hemodialysis, compared with both control groups (hepatitis C-positive blood bank donors and hepatitis C-negative patients undergoing hemodialysis). Seventeen of 33 HCV antibodies-positive males undergoing hemodialysis had anti-ENA antibodies, compared with 16 of 31 females, indicating no sex related difference. This study emphasizes the high prevalence of HCV infection in our hemodialysis patients, comparable to that of other Middle Eastern countries, but higher than Western ones. A strong association was observed between anti-HCV positivity and hemodialysis duration, as well as anti-ENA antibody profile. However, these

    The field of perioperative medicine has garnered legitimacy during the past 3 decades. Adverse cardiovascular events in the perioperative period account for significant morbidity and mortality. Although testing patients preoperatively to detect ischemia and identify those who may benefit from modifications in care is a tempting strategy, risk assessment should account for posterior probability. Validated risk stratification tools, such as the Revised Cardiac Risk Index or the National Surgical Quality Improvement Program risk calculator, can assist in the identification of patients for whom preoperative noninvasive testing is justified and may change the plan of care. Furthermore, current guidelines emphasize that prophylactic coronary revascularization should not be performed exclusively for the purposes of reducing the risk of perioperative events. There has been enthusiasm for medical therapies that may reduce the risk of adverse cardiovascular events in the perioperative period. Current guidelines encourage the perioperative use of β-blockade in patients already receiving such therapy and caution against initiating such therapy on the day of the surgical procedure. Reduction of morbidity and mortality in the perioperative period relies on an understanding of the myriad physiological perturbations in this period and thoughtful selection of patients for further testing and treatment.

    Atrial pacing (AP) procedure was carried out in 11 cardioischemic patients to reproduce tachycardia-induced myocardial ischemia. Six control subjects underwent the same procedure until the maximum pacing rate was reached. During the procedure, endothelin-1 (ET-1) and plasma lactate levels were measured in the coronary sinus and in the aortic root. In all the patients, atrial pacing provoked electrocardiographic signs and metabolic evidence of myocardial ischemia and a significant decrease (p<0.001) in left ventricular ejection fraction. At AP-induced ischemia, coronary sinus (17.31 +/- 4.20 pg/mL) and arterial (9.60 +/- 3.31 pg/mL) ET-1 plasma levels were significantly different (p<0.001) in the patients. On the contrary, at maximum pacing rate, no significant difference (p=0.186) emerged between coronary sinus (9.72 +/- 1.09 pg/mL) and arterial (8.95 +/- 0.75 pg/mL) plasma ET-1 levels in the control group. These results suggest that, in cardioischemic patients, tachycardia can induce the coronary endothelium to release significant amounts of ET-1. PMID:11563817

    Background The purpose of this retrospective study was to determine the prevalence of sarcopenia and sarcopenic obesity among patients who underwent orthopedic surgery (OS). Methods A total of 222 patients were reviewed immediately after or prior to OS. In the control group, 364 patients from outpatient departments (OPDs) who did not have any OS were enrolled. Whole-body dual-energy X-ray absorptiometry was used to analyze body composition. Skeletal muscle mass was adjusted for height squared, total body weight, and height and fat mass (residuals). Obesity was defined as body mass index (BMI) > 25.0 kg/m2. Results The prevalence of sarcopenia in the OS group was 25.7%, 44.1%, and 26.6%, respectively, according to the 3 different criteria. The prevalence was significantly lower in the OPD group (6.0%, 33.1%, and 14.8%, respectively). The highest rates of sarcopenia with height-adjusted definition were seen in patients with a femoral neck fracture. In the multivariate analysis, factors associated with sarcopenia were male gender, older age, and lower BMI (odds ratio [OR]: 28.38, 1.03, and 1.83, respectively) when muscle mass was adjusted for height, whereas male gender, older age, and higher BMI were associated with sarcopenia (OR: 1.04, 2.57, and 1.83, respectively) when adjusted for weight. When residuals were used as a cutoff, decreased BMI and total hip bone mineral density (0.1 g/cm2) were independent risk factors associated with sarcopenia (OR: 1.09 and 1.05). The prevalence of sarcopenic obesity ranged from 1.8% to 21.2%. Conclusions Our study demonstrated a high prevalence of sarcopenia among OS patients. PMID:27247746

    Purposes To assess the cardiovascular responses during constant load walking and to identify predictors of this response in peripheral artery disease (PAD) patients. Methods Seventy-nine patients with PAD performed a constant load treadmill test (2 mph, 0% grade). During the test, systolic blood pressure (BP), diastolic BP, and heart rate (HR) were obtained at the fourth minute to the last minute of exercise. Patients were also characterized on demographic measures, cardiovascular risk factors, baseline exercise performance and vascular measures. Results During constant load walking, there was a significant increase (p<0.01) in systolic BP (+12 ± 10 mmHg), diastolic BP (+6 ± 9 mmHg), and HR (+5 ± 5 bpm). The HR responses was negatively correlated with ischemic window (r= −0.23; p<0.05), expressed as an area under the curve of the resting ankle systolic BP and its recovery from maximal graded treadmill test, and positively correlated with the HR during the first minute of recovery from maximal graded treadmill test (r= 0.27; p<0.05). The increase in cardiovascular variables during constant load walking was greater in subjects with higher body mass index and in men (p<0.05). Conclusion Patients with PAD had an increased cardiovascular response during constant load walking, and these responses were greater in obese patients and in men. The clinical implication is that PAD patients engaged in walking training programs, particularly men and those with obesity, require frequent assessment of cardiovascular parameters to avoid exaggerated increases in BP and HR during constant load walking.

    The risk of venous thromboembolism (VTE) in rheumatoid arthritis (RA) and the higher incidence of RA patients undergoing major orthopedic surgery is well recognized. The objective of the present study is to describe the incidence of VTE and discuss the correct prophylaxis in RA patients undergoing knee or hip replacement. A systematic review of studies on thromboprophylaxis in RA patients undergoing major orthopedic surgery was performed. Detailed information was extracted to calculate the rate of VTE in RA orthopedic patients and analyze the thromboprophylaxis performed and bleeding complications. Eight articles were eligible for full review. No difference in the overall rate of VTE was observed between RA patients and controls. No significant differences were found in RA patients in terms of bleeding complications. The data on the optimal prophylaxis to be used in RA patients were insufficient to recommend any of the several options available. In the absence of dedicated guidelines for the care of RA patients undergoing orthopedic surgery, management must be individualized to obtain favorable patient outcome, weighing up all the factors that might put the patient at risk for higher bleeding and thrombotic events.

    Symptomatic degenerative central lumbar spinal stenosis (LSS) is a frequent indication for decompressive spinal surgery, to reduce spinal claudication. No data are as yet available on the effect of surgery on the level of activity measured with objective long-term monitoring. The aim of this prospective, controlled study was to objectively quantify the level of activity in central LSS patients before and after surgery, using a continuous measurement device. The objective data were correlated with subjective clinical results and the radiographic degree of stenosis. Forty-seven patients with central LSS and typical spinal claudication scheduled for surgery were included. The level of activity (number of gait cycles) was quantified for 7 consecutive days using the StepWatch Activity Monitor (SAM). Visual analogue scales (VAS) for back and leg pain, Oswestry disability index and Roland–Morris score were used to assess the patients’ clinical status. The patients were investigated before surgery and 3 and 12 months after surgery. In addition, the radiographic extent of central LSS was measured digitally on preoperative magnetic resonance imaging or computed tomography. The following results were found preoperatively: 3,578 gait cycles/day, VAS for back pain 5.7 and for leg pain 6.5. Three months after surgery, the patients showed improvement: 4,145 gait cycles/day, VAS for back pain 4.0 and for leg pain 3.0. Twelve months after surgery, the improvement continued: 4,335 gait cycles/day, VAS for back pain 4.1 and for leg pain 3.3. The clinical results and SAM results showed significant improvement when preoperative data were compared with data 3 and 12 months after surgery. The results 12 months after surgery did not differ significantly from those 3 months after surgery. The level of activity correlated significantly with the degree of leg pain. The mean cross-sectional area of the spinal canal at the central LSS was 94 mm2. The radiographic results did not

    Peripheral artery disease affects over eight million Americans and is associated with an increased risk of mortality, cardiovascular disease, functional limitation, and limb loss. In its most severe form, critical limb ischemia, patients are often treated with lower extremity (LE) amputation (LEA), although the overall incidence of LEA is declining. In the US, there is significant geographic variation in the performing of major LEA. The rate of death after major LEA in the US is approximately 48% at 1 year and 71% at 3 years. Despite this significant morbidity and mortality, the use of diagnostic testing (both noninvasive and invasive testing) in the year prior to LEA is low and varies based on patient, provider, and regional factors. In this review we discuss the significance of LEA and methods to reduce its occurrence. These methods include improved recognition of the risk factors for LEA by clinicians and patients, strong advocacy for noninvasive and/or invasive imaging prior to LEA, improved endovascular revascularization techniques, and novel therapies.

    Abstract With 185 million people chronically infected globally, hepatitis C is a leading bloodborne infection. All-oral regimens of direct acting agents have superior efficacy compared to the historical interferon-based regimens and are significantly more tolerable. However, trials of both types of regimens have often excluded patients on immunosuppressive medications for reasons other than organ transplantation. Yet, these patients—most often suffering from malignancy or autoimmune diseases—could stand to benefit from these treatments. In this study, we systematically review the literature on the treatment of hepatitis C in these neglected populations. Research on patients with organ transplants is more robust and this literature is reviewed here non-systematically. Our systematic review produced 2273 unique works, of which 56 met our inclusion criteria and were used in our review. The quality of data was low; only 3 of the 56 studies were randomized controlled trials. Sustained virologic response was reported sporadically. Interferon-containing regimens achieved this end-point at rates comparable to that in immunocompetent individuals. Severe adverse effects and death were rare. Data on all-oral regimens were sparse, but in the most robust study, rates of sustained virologic response were again comparable to immunocompetent individuals (40/41). Efficacy and safety of interferon-containing regimens and all-oral regimens were similar to rates in immunocompetent individuals; however, there were few interventional trials. The large number of case reports and case series makes conclusions vulnerable to publication bias. While firm conclusions are challenging, given the dearth of high-quality studies, our results demonstrate that antiviral therapy can be safe and effective. The advent of all-oral regimens offers patients and clinicians greatly increased chances of cure and fewer side effects. Preliminary data reveal that these regimens may confer such benefits in

    ABSTRACT Background: Morbid obesity is a multifactorial disease that increasingly is being treated by surgery. Aim: To evaluate gastric histopathological changes in obese, and to compare with patients who underwent gastrojejunal bypass and the jejunal mucosa after the surgery. Methods: This is an observational study performed at a tertiary public hospital, evaluating endoscopic biopsies from 36 preoperative patients and 35 postoperative. Results: In the preoperative group, 80.6% had chronic gastritis, which was active in 38.9% (77.1% and 20.1%, respectively, in the postoperative). The postoperative group had a significant reduction in H. pylori infection (p=0.0001). A longer length of the gastric stump and a time since surgery of more than two years were associated with Helicobacter pylori infection. The jejunal mucosa was normal in 91.4% and showed slight nonspecific chronic inflammation in 8.6%. Conclusion: There was a reduction in the incidence of Helicobacter pylori infection in the postoperative group. A longer length of the gastric stump and longer time elapsed since surgery were associated with Helicobacter pylori infection. The jejunal mucosa was considered normal in an absolute majority of patients. PMID:27683773

    Average life expectancy is increasing in the western world resulting in a growing number of frail individuals with coronary heart disease, often associated with comorbidities. Decisions to proceed to invasive interventions in elderly frail patients is challenging because they may gain benefit, but are also at risk of procedure-related complications. Current risk scores designed to predict mortality in cardiac procedures are mainly based on clinical and angiographic factors, with limitations in the elderly because they are mainly derived from a middle-aged population, do not account for frailty and do not predict the impact of the procedure on quality of life which often matters more to elderly patients than mortality. Frailty assessment has emerged as a measure of biological age that correlates well with quality of life, hospital admissions and mortality. Potentially, the incorporation of frailty into current risk assessment models will cause a shift towards more appropriate care. The need for a more accurate method of risk stratification incorporating frailty, particularly for elderly patients is pressing. This article reviews the association between frailty and cardiovascular disease, the impact of frailty on outcomes of cardiac interventions and suggests ways in which frailty assessment could be incorporated into cardiology clinical practice.

    The proper use of anticoagulants is crucial for ensuring optimal patient outcomes post percutaneous interventions in the cardiac catheterization laboratory. Anticoagulant agents such as unfractionated heparin, a thrombin inhibitor; low-molecular weight heparins, predominantly Factor Xa inhibitors; fondaparinux, a Factor Xa inhibitor and bivalirudin, a direct thrombin inhibitor have been developed to target various steps in the coagulation cascade to prevent formation of thrombin. Optimal anticoagulation achieves the correct balance between thrombosis and bleeding and is related to optimal outcomes with minimal complications. This review will discuss the mechanisms and appropriate use of current and emerging anticoagulant therapies used during percutaneous interventions.

    The effectiveness of colonoscopy is directly affected by the quality of the patient's bowel preparation. Patients with lower socioeconomic status (SES) are at increased risk of having suboptimal bowel prep quality. Patient navigators can play a key role in clarifying bowel prep instructions. The aim of the present study was to examine the quality of bowel prep and its predictors among individuals of low SES undergoing screening colonoscopy with patient navigation. Participants (N = 607) were individuals of low SES who completed a screening colonoscopy with patient navigation. Demographic information was collected after the participants received a primary care referral for a screening colonoscopy. After the colonoscopy was completed, medical charts were reviewed to document the colonoscopists' bowel prep quality ratings. A total of 6.8% (41/607) of the sample had poor bowel prep, which significantly correlated with having a colonoscopy that did not reach the cecum. If fair preps were included, approximately 19.3% (117/607) of our cohort would be considered to have suboptimal bowel prep. Our suboptimal bowel prep rates were better than those reported from other low SES samples.

    Lanthanum carbonate (LaC) is a non-calcium-based phosphate binder used to treat hyperphosphatemia in patients with chronic kidney disease. Oral administration of LaC is difficult in patients undergoing tube feeding or those who are of advanced age because it is essential to chew the LaC tablet sufficiently before swallowing it. We report two cases in whom crushed LaC was used in hemodialysis patients undergoing tube feeding. In both cases, previously crushed LaC was mixed into enteral nutrients. We found that LaC administered this way was effective for decreasing serum phosphorus levels.

    2014-01-01

    With cancer survival rate climbing up over the past three decades, quality of life for cancer patients has become an issue of major concern. Oral health plays an important part in one's overall quality of life. However, oral health status can be severely hampered by side effects of cancer therapies including surgery, chemotherapy, radiotherapy, and hematopoietic stem cell transplantation. Moreover, prevention and treatment of these complications are often overlooked in clinical practice. The present paper aims at drawing health care professionals' attention to oral complications associated with cancer therapy by giving a comprehensive review. Brief comments on contemporary cancer therapies will be given first, followed by detailed description of oral complications associated with cancer therapy. Finally, a summary of preventive strategies and treatment options for common oral complications including oral mucositis, oral infections, xerostomia, and dysgeusia will be given. PMID:24511293

    Patients on peritoneal dialysis (PD) are at high cardiovascular risk. Although some risk factors are unmodifiable (for example, age, sex, genetics), others are exacerbated in the unfriendly uremic milieu (inflammation, oxidative stress, mineral disturbances) or contribute per se to kidney disease and cardiovascular progression (diabetes mellitus, hypertension). Moreover, several factors associated with PD therapy may both increase (by altered lipid profile, hyperinsulinemia, and formation of advanced glycation end-products) and decrease (by better blood pressure control and anemia management) cardiovascular risk. The present review discusses recent findings and therapy trends in cardiovascular research on the PD population, with emphasis on the roles of inflammation, insulin resistance, homocysteinemia, dyslipidemia, vascular calcification, and genetics/epigenetics.

    The pharmacokinetics of cefepime were studied in 10 male patients receiving continuous ambulatory peritoneal dialysis therapy. Five patients received a single 1,000-mg dose and the other five received a single 2,000-mg dose; all doses were given as 30-min intravenous infusions. Serial plasma, urine, and peritoneal dialysate samples were collected; and the concentrations of cefepime in these fluids were measured over 72 h by using a high-performance liquid chromatographic assay with UV detection. Pharmacokinetic parameters were calculated by noncompartmental methods. The peak concentrations in plasma and the areas under the plasma concentration-versus-time curve for the 2,000-mg dose group were twice as high as those observed for the 1,000-mg dose group. The elimination half-life of cefepime was about 18 h and was independent of the dose. The steady-state volume of distribution was about 22 liters, and values for the 1,000- and 2,000-mg doses were not significantly different. The values for total body clearance and peritoneal dialysis clearance were about 15 and 4 ml/min, respectively. No dose dependency was observed for the clearance estimates. Over the 72-h sampling period, about 26% of the dose was excreted intact into the peritoneal dialysis fluid. For 48 h postdose, mean concentrations of cefepime in dialysate at the end of each dialysis interval exceeded the reported MICs for 90% of the isolates (MIC90s) for bacteria which commonly cause peritonitis resulting from continuous peritoneal dialysis. A parenteral dose of 1,000 or 2,000 mg of cefepime every 48 h would maintain the antibiotic levels in plasma and peritoneal fluid above the MIC90s for the most susceptible bacteria for the treatment of systemic and intraperitoneal infections [corrected].

    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 protein (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.

    This study aimed to collect data on the oral health status of patients undergoing treatment for head and neck oncology across Northern Ireland. Data were collected on all patients referred to the Northern Ireland Multidisciplinary Head and Neck Oncology Team for discussion and treatment planning. Each patient underwent pre-treatment dental assessment in the Centre for Dentistry, Queen's University Belfast, between June 2013 and November 2014. Data were collected from clinical oral examinations supplemented with intra-oral radiographs. During the course of the study 96 patients were assessed and the levels of dental disease observed in this cohort were high. On clinical examination 43% were diagnosed with caries and 46% with periodontal disease. Ten patients were completely edentate. The disease profile of this patient group presents significant challenges to dental services tasked with rendering patients dentally fit prior to undergoing oncology treatment. PMID:27424336

    This study aimed to evaluate the incidence of clinically significant venous thromboembolic events (VTE) in Asian patients undergoing total knee arthroplasty (TKA) without anticoagulation. All patients who underwent TKA by a single surgeon from 2006 to 2010 in Singapore General Hospital were reviewed. Only symptomatic patients were referred for ultrasonography. Of the 531 patients reviewed, 3 patients developed symptoms of deep vein thrombosis with subsequent ultrasonographic confirmation, whereas 1 patient developed fatal pulmonary embolism without any clinical or radiologic evidence of deep vein thrombosis. Hence, the incidence of clinically significant VTE was 0.75%. Given the low incidence of clinically significant VTE, there is a need to review the current practice of routine chemoprophylaxis in Asian patients undergoing TKA.

    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

    Purpose. To evaluate outcomes of peripheral iridotomy (PI) for initial management of primary angle closure suspects (PACS), chronic primary angle closure (CPAC), and chronic primary angle closure glaucoma (CPACG). Patients and Methods. Seventy-nine eyes with PACS, CPAC, or CPACG and better than 20/50 visual acuity that underwent PI as initial management were included. Eyes with previous acute angle closure attacks, laser trabeculoplasties, surgeries, or intraocular injections were excluded. Additional treatments, glaucomatous progression, intraocular pressure, visual acuity, and the number of medications were evaluated. Results. The mean followup was 57.1 ± 29.0 months (range 13.8–150.6 months). Sixty-eight eyes (86.1%) underwent additional medical, laser, or surgical treatment. Forty eyes (50.6%) underwent lens extraction due to reduced visual acuity. The mean 10× logMAR visual acuity score for all patients significantly declined from 0.94 ± 1.12 at baseline to 1.83 ± 3.49 (N = 79, P = 0.0261) at the last followup. Conclusions. Most patients who undergo PI for CPAC spectrum will require additional intervention for either IOP lowering or improvement of visual acuity. This suggests that a procedure that not only deepens the angle but also lowers IOP and improves visual acuity would be desirable as further intervention could be avoided. Evaluation of techniques that achieve all 3 goals is warranted. PMID:24558607

    To establish whether radioisotope-labeled fibrinogen leg scanning is of value in the context of hip surgery, we propsectively studied 21 consectuvie patients undergoing either total hip replacement (14) or open repair of a hip fracture (seven) with leg scans, contrast phlebography, and ventilation and perfusion lung scans. We found that in eight patients (38%), venous thromboembolism developed postoperatively. Agreement between phlebographic and leg scanning results was excellent. In no patient as venous thrombosis limited to the thigh on the operated-on side, a vital consideration in application of fibrinogen leg scanning to this patient population. Two patients had lung scan changes indicative of embolism; both had thrombi extending into thigh veins. Leg scanning with radioisotope-labeled fibrinogen appears to be a useful method for monitoring patients undergoing hip surgery, if the upper three counting points on the operated-on side are excluded.

    Atrial fibrillation (AF) and coronary artery disease (CAD) often present concomitantly. Given the increased risk of thrombotic complications with either of them but different pathogenesis of clot formation, combined antithrombotic therapy is necessary in patients developing acute coronary syndrome and/or undergoing percutaneous coronary intervention (PCI). Different antithrombotic regimens in this group of patients have been summarized and discussed earlier. Triple therapy remains the treatment of choice in these patients despite the increased risk of hemorrhagic complications. Given the absence of evidence from randomized controlled trials, balancing the risk of stroke and stent thrombosis against the risk of major bleeding is a challenge. Precise stroke and bleeding risk assessment is an essential part of the decision making process regarding antithrombotic management. Continuing the discussion of current concepts and concerns of antithrombotic management in AF patients undergoing PCI, we emphasize the importance of various strategies to reduce bleeding in the modern era, namely, radial access combined with careful selection of a P2Y₁₂ receptor inhibitor, use of newer drug-eluting stents, and uninterrupted anticoagulation for patients undergoing procedures. We also focus on the role of the non-vitamin K oral anticoagulants (novel oral anticoagulants, eg, dabigatran, rivaroxaban, apixaban, and edoxaban) which are increasingly used for stroke prevention in AF. Finally, recent recommendations on the management of antithrombotic therapy in AF patients presenting with acute coronary syndrome and/or undergoing PCI as well as ongoing clinical trials and future directions are highlighted.

    Purpose The goal in this study was to determine the incidence of subclinical neuropathy in treatment-naive patients with multiple myeloma (MM) with no history of peripheral neuropathy using quantitative sensory tests (QSTs) and its correlation with innervation density of the extremities using noninvasive laser reflectance confocal microscopy. Patients and Methods QST results were collected for 27 patients with a diagnosis of MM and compared with data collected from 30 age- and sex-matched healthy volunteers. Skin temperature, sensorimotor function (grooved pegboard test), and detection thresholds for temperature, sharpness, and low-threshold mechanical stimuli (von Frey monofilaments and bumps detection test) were measured. Meissner's corpuscle (MC) density in the fingertips was assessed using in vivo laser reflectance confocal microscopy. Results Patients showed a high incidence (> 80%) of ≥ one subclinical QST deficit. These included increased von Frey, bumps, and warmth detection thresholds as compared with healthy volunteers. Patients also showed increases in cold pain, sensorimotor deficits (grooved pegboard test), and higher overall neuropathy scores. MC density was significantly lower in patients than controls and showed significant inverse correlation with bumps detection threshold. Conclusion Patients with MM commonly present with sensory and sensorimotor deficits before undergoing treatment, and these deficits seem to result from disease-related decreases in peripheral innervation density.

    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.

    Background: Anxiety is a common preprocedural problem and during processing especially in interventional medical processes. Aim: Aim of this study was to assess the level of anxiety in patients who will undergo upper gastrointestinal endoscopy and coloscopy. Methods: Five hundred patients scheduled to undergo sedation for elective upper gastrointestinal endoscopy and colonoscopy were studied. Beck Anxiety Inventory (BAI) was administered to each patient before brought to the endoscopy room. Demographic data of patients were collected. Results: BAI scores and anxiety levels were significantly lower in; males compared to females, patients with no comorbidity compared to patients with comorbidity (both P values < 0.001). BAI scores were significantly lower in patients educational status university and upper compared to patients educational status primary-high school (p=0.026). There were no significant difference between BAI and anxiety levels compared to procedures (Respectively, P=0.144 P=0.054). There were no significant difference between BAI scores and anxiety levels compared to age groups (Respectively, P=0.301 P=0.214). Conclusions: We think that level of anxiety in patients who will undergo upper gastrointestinal endoscopy and colonoscopy was effected by presence of comorbidities and gender but was not effected by features such as age, procedure type and educational status.

    Background: Patients undergoing pacemaker implantation often experience anxiety and fear. As such, studies have focused on the mechanisms that relieve the negative emotions caused by the intervention. Continuous nursing is a safe and effective nursing mode. In this study, continuous nursing intervention was provided for elderly patients undergoing pacemaker implantation and an empirical investigation was performed to determine the effects of their negative emotion and disease-coping ability. Methods: Overall, 114 (68 males and 46 females) elderly patients who were undergoing pacemaker implantation from Harbin City (China), were enrolled in the study. The patients were divided into two groups, namely, the control group and the intervention group, based on different nursing methods. Routine nursing was applied to the control group; continuous nursing support was provided for the intervention group from January 2014 to January 2015. The nursing results of the two groups were compared. These results were also evaluated using self-rating depression scale, self-rating anxiety scale, and trait coping style questionnaire. Result: The effects of depression and anxiety intervention were significant in the intervention group (P<0.05). Compared with the control group, the intervention group did not significantly differ. The coping style of the intervention group elicited significant effects. Compared with the control group, the intervention group was significantly different (P < 0.05). Conclusion: Continuous nursing can relieve the negative emotion and improve the negative coping style of patients undergoing pacemaker implantation. PMID:26576373

    Peripheral neuropathy and hypertension caused by lead intoxication are reported in two children with sickle cell anemia. One child had generalized weakness in the initial occurrence and distal paralysis during a relapse two years later. The second child had foot and wrist drop. Both had slow peripheral nerve conduction velocities during the episodes. Chelation therapy was successful and resulted in a return of strength (over a period of several months) and a normalization of the blood pressures. Children with sickle cell anemia who are subjected to lead intoxication appear to be predisposed to peripheral nerve damage.

    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.

    2014-01-01

    The cardiac patient undergoing major urologic surgery is a complex case requiring a great attention by the anesthesiologist. Number of this group of patients having to go through this procedure is constantly increasing, due to prolonged life, increased agressiveness of surgery and increased anesthesia’s safety. The anesthesiologist usually has to deal with several problems of the patient, such as hypertension, chronic heart failure, coronary artery disease, rhythm disturbances, intraoperative hemodymanic changes, intraoperative bleeding, perioperative fluid imbalance, and metabolic disturbances. A cardiac patient undergoing major urologic surgery is a complex case requiring a great attention by the anesthesiologist. The scope of this review article is to present the most frequent issues encountered with this group of patients, and to synthetically discuss the respective strategies and maneuvers during perioperative period, which is the major challenge for the anesthesiologist.

    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.

    Background This randomized controlled study evaluated the efficacy of intravenous patient-controlled analgesia (IV-PCA) with fentanyl and ketorolac for neurosurgical patients, and compared the effectiveness of IV-PCA with intermittent analgesics injection. Methods The patients undergoing craniotomy were randomly assigned to two groups. Patients of group P (n = 53) received fentanyl (0.2 µg/kg/hr) and ketorolac (0.3 mg/kg/hr) via IV-PCA, and those of group N (n = 53) received intermittent fentanyl or ketorolac injection as needed. Pain was evaluated using a 0-10 visual analogue scale (VAS) at postoperative 1, 4, and 24 hr. The amount of infused analgesic drugs, Glasgow Coma Scale (GCS) score, systolic arterial pressure, heart rate, respiratory rate, and the incidence of nausea and miosis were measured at the same time points. Results Although VAS of pain (VASp) was comparable at postoperative 1 hr (P = 0.168) between the two groups, the group P had significantly lower VASp at postoperative 4 hr (P = 0.007) and 24 hr (P = 0.017). In group P, less analgesic drugs were administered at postoperative 1 hr, and more analgesic drugs were administered at postoperative 24 hr. There were no differences between two groups with respect to nausea, GCS, systolic arterial pressure, and heart rate. IV-PCA did not further incur respiratory depression or miosis. Conclusions IV-PCA with fentanyl and ketorolac after craniotomy is more effective analgesic technique, without adverse events, than the intermittent administration of analgesics. PMID:21359078

    Despite the increasing prevalence of sleep apnoea, little information is available regarding its impact on the peri-operative outcome of patients undergoing posterior lumbar fusion. Using a national database, patients who underwent lumbar fusion between 2006 and 2010 were identified, sub-grouped by diagnosis of sleep apnoea and compared. The impact of sleep apnoea on various outcome measures was assessed by regression analysis. The records of 84 655 patients undergoing posterior lumbar fusion were identified and 7.28% also had a diagnostic code for sleep apnoea. Compared with patients without sleep apnoea, these patients were older, more frequently female, had a higher comorbidity burden and higher rates of peri-operative complications, post-operative mechanical ventilation, blood transfusion, and intensive care. Patients with sleep apnoea also had longer and more costly periods of hospitalisation. In the regression analysis, sleep apnoea emerged as an independent risk factor for the development of peri-operative complications (Odds Ratio (OR) 1.50, Confidence Interval (CI) 1.38;1.62), blood transfusions (OR 1.12, CI 1.03;1.23), mechanical ventilation (OR 6.97, CI 5.90;8.23), critical care services (OR 1.86, CI 1.71;2.03), prolonged hospitalisation and increased cost (OR 1.28, CI 1.19;1.37; OR 1.10, CI 1.03;1.18). Patients with sleep apnoea who undergo posterior lumbar fusion pose significant challenges to clinicians. PMID:24493191

    The purpose of this study was to retrospectively analyze the feasibility of outpatient management without initial assessment for febrile patients undergoing adjuvant chemotherapy for breast cancer. A total of 131 consecutive patients with breast cancer treated with adjuvant or neoadjuvant chemotherapy from 2011 to 2013 at Osaka Medical College Hospital (Osaka, Japan) were retrospectively reviewed. In the case of developing a fever (body temperature, ≥38°C), the outpatients had been instructed to take previously prescribed oral antibiotics for 3 days without any initial assessment, and if no improvement had occurred by then, they were required to visit the hospital for examination and to undergo treatment based on the results of a risk assessment for complications. The primary aim of the present study was to assess the outcome of febrile episodes, while the secondary aim was to assess the incidence of febrile episodes, hospitalizations, and the type of chemotherapy. The 131 patients received 840 chemotherapy administrations. Fifty-five patients (42.0%) had a total of 75 febrile episodes after 840 chemotherapy administrations (8.9%). Treatment failure occurred in 12 of the 75 episodes (16.0%) in 11 of the 55 patients (20.0%). Only four episodes required hospitalization. Treatment success was achieved in 63 episodes (84.0%). In conclusion, the feasibility of outpatient management without initial assessment was evaluated in the present study for febrile patients undergoing adjuvant chemotherapy for breast cancer, and the outpatient strategy regimen may be safe and convenient for these patients.

    Introduction: The presence of metabolic syndrome in men with prostate cancer (PCa) undergoing androgen-deprivation therapy (ADT), especially intermittent type, has not been completely evaluated. The aim of this study is to evaluate metabolic syndrome in men with PCa undergoing intermittent ADT. Methods: In this longitudinal study, we studied the prevalence of metabolic syndrome and its components in 190 patients who were undergoing intermittent ADT. The metabolic syndrome was defined according to the Adult Treatment Panel III criteria. All metabolic parameters, including lipid profile, blood glucose, blood pressures, and waist circumferences of the patients were measured six and 12 months after treatment. Results: Mean age of the patients was 67.5 ± 6.74 years. The incidence of metabolic syndrome after six and 12 months was 6.8% and 14.7%, respectively. Analysis of various components of the metabolic syndrome revealed that patients had significantly higher overall prevalence of hyperglycemia, abdominal obesity, and hypertriglyceridemia in their six- and 12-month followups, but blood pressure has not been changed in the same period except for diastolic blood pressure after six months. Conclusions: Although there was an increased risk of metabolic syndrome in patients receiving intermittent ADT, it was lower than other studies that treated the same patients with continuous ADT. Also it seems that intermittent ADT has less metabolic complications than continuous ADT and could be used as a safe alternative in patients with advanced and metastatic PCa.

    The lack of consistent definitions and nomenclature across clinical trials of novel devices, drugs, or biologics poses a significant barrier to accrual of knowledge in and across peripheral artery disease therapies and technologies. Recognizing this problem, the Peripheral Academic Research Consortium, together with the U.S. Food and Drug Administration and the Japanese Pharmaceuticals and Medical Devices Agency, has developed a series of pragmatic consensus definitions for patients being treated for peripheral artery disease affecting the lower extremities. These consensus definitions include the clinical presentation, anatomic depiction, interventional outcomes, surrogate imaging and physiological follow-up, and clinical outcomes of patients with lower-extremity peripheral artery disease. Consistent application of these definitions in clinical trials evaluating novel revascularization technologies should result in more efficient regulatory evaluation and best practice guidelines to inform clinical decisions in patients with lower extremity peripheral artery disease.

    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. PMID:20153859

    The increasing number of patients with coronary artery disease (CAD) undergoing major noncardiac surgery justifies guidelines concerning preoperative cardiac evaluation. This is compounded by increasing chances for a volatile perioperative period if the underlying cardiac problems are left uncorrected prior to major noncardiac surgeries. Preoperative cardiac evaluation requires the clinician to assess the patient's probability to have CAD, severity and stability of CAD, placing these in perspective regarding the likelihood of a perioperative cardiac complication based on the planned surgical procedure. Coronary events like new onset ischemia, infarction, or revascularization, induce a high-risk period of 6 weeks, and an intermediate-risk period of 3 months before performing noncardiac surgery. This delay is unwarranted in cases where surgery is the mainstay of treatment. The objective of this review is to offer a comprehensive algorithm in the preoperative assessment of patients undergoing noncardiac surgery and highlight the importance of myocardial perfusion imaging in risk stratifying these patients.

    Little data exists comparing acute post-operative outcomes in patients with different types of inflammatory arthritis (IA) after undergoing a total knee arthroplasty (TKA). Our objectives were to compare perioperative complications and determine the most common complications between the different IA subtypes compared with patients with osteoarthritis undergoing primary TKA. We found significant differences when comparing complications within the different subtypes of IA. RA patients, despite having a greater number of comorbidities had a reduced rate of medical complications postoperatively compared to the OA cohort. All of the inflammatory subtypes had a higher rate of orthopedic complications postoperatively compared to the OA group except for patients with AS. However, ankylosing spondylitis had the highest mortality rate as well as medical complication rate among the subtypes. PMID:26111792

    To determine the incidence of fetomaternal hemorrhage in patients undergoing cesarean section, Kleihauer-Betke tests were performed in the immediate postoperative period on 199 parturients. Some degree of hemorrhage was detected in 18.5% of patients, with 2.5% demonstrating greater than 30 ml of fetal blood. Comparison of groups on the basis of indication for cesarean delivery revealed no difference in rates of fetal hemorrhage. Because patients with greater than 30 ml of fetal blood would not be adequately protected from Rh sensitization by the standard 300 micrograms dose of Rh immune globulin, we recommend screening all Rh-negative patients undergoing cesarean section for the presence of significant fetomaternal hemorrhage.

    Possible cytogenic alterations due to radiologic contrast medium in patients undergoing a common radiologic examination is studied. Two groups of 20 patients each were used. Group I consisted of patients undergoing excretory urography, using sodium and meglumine diatrizoate as contrast. A different agent, sodium and meglumine ioxaglate, was used with group II. Three blood samples were taken from each patient before urography, immediately after urography, and 1 week later. The frequency of sister chromatid exchanges (SCE) and chromosomal aberrations (CA) were found to increase significantly in the B samples from both groups, that of group I being higher (P less than .01 compared with P less than .05). Furthermore, these alterations were found to persist in the C samples from group I. No modification of the Proliferating Rate Index (PRI) was found. The osmolarity or other components of the contrast media studied could be involved in the process. The results indicate that ioxaglate produces less cytogenic damage than diatrizoate.

    Context: Postoperative throat complaints such as postoperative sore throat (POST), dysphagia, and hoarseness frequently arises after tracheal intubation and throat packing for patient undergoing general anesthesia. This condition is very disturbing to patient. Avoiding POST is a major priority for these patients because preventing postoperative complications contributes to patient satisfaction. Aims: To describe and analyze the postoperative throat effects of nasopharyngeal packing and oropharyngeal packing in patients undergoing nasal surgery. Settings and Design: A randomized comparative study. Subjects and Methods: After obtaining approval of Ethical Committee 40 patients were included in study. After this patient were randomly allocated into two groups of 20 each. Group A - in which the oropharynx was packed and Group B - inwhich the nasopharynx was packed. General anesthesia were given and throat packing was done and patients were interviewed postoperatively for any throat complications such as sore throat, difficulty in swallowing (dysphagia), hoarseness of voice, throat irritation, and any other symptom pertaining to the study were noted and data were analyzed. Statistical Analysis Used: T-test to compare the age, while Chi-square test and Fisher's exact test were used to compare sex distribution, sore throat, dysphagia, hoarseness, and throat irritation. Results: Results showed statistically significant difference in incidence and severity of POST in Group A patients when compared to Group B patients to be more. Patients in Group A had a higher incidence of dysphagia when compared to their Group B counterparts. With respect to the incidence of hoarseness and throat irritation, there was no statistical significance between the groups. Conclusion: We concluded that the site of pharyngeal packing influences the incidence and severity of POST and as well as the incidence of dysphagia after general anesthesia.

    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.

    Background Secondary hyperparathyroidism (SHPT) is a major disorder in patients with chronic renal disease with or without dialysis. Air pollution has been confirmed as being associated with increased incidence of human morbidity and mortality. To our knowledge, investigating air pollution as a dialysis-unrelated factor for SHPT in patients undergoing dialysis is limited. We developed this study to assess the effect of air pollution and other important risk factors on SHPT in patients undergoing peritoneal dialysis (PD). Materials and methods We recruited a total of 141 patients who did not have diabetes mellitus, were nonsmokers, and were undergoing PD in this cross-sectional study. We analyzed the difference in air quality based on the patients’ living areas. We estimated demographic, hematological, nutritional, inflammatory, biochemical, air pollutant, and dialysis-related data based on this cross-sectional study. Subgroup analysis of the relationship between air pollutants and the clinical variables and having or not having hyperparathyroidism (HPT) (intact parathyroid hormone level ≥180 pg/dL) was also performed. Results A total of 141 patients undergoing PD (30 men and 111 women) were enrolled in the study. Sixty-eight patients had SHPT. In a binary logistic regression, high environmental CO exposure (odds ratio [OR] 3.22, 95% confidence interval [CI] 1.42–7.28; P=0.005), serum phosphate levels (OR 1.66, 95% CI 1.17–2.37; P=0.005), hypoalbuminemia (OR 3.76, 95% CI 1.29–10.94; P=0.015), and use of calcitriol (OR 8.25, 95% CI 3.43–19.85; P<0.001) were positively associated with SHPT. Conclusion The findings of this cross-sectional study indicated the presence of an association between environmental CO exposure and SHPT in patients undergoing PD who did not have diabetes mellitus. Therefore, poor environmental air quality may be a risk factor for deterioration of SHPT in patients undergoing PD. PMID:26396525

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

    Objectives To identify patient-reported outcome measures (PROMs) that have been developed and/or used with patients undergoing hip or knee replacement surgery and to provide a shortlist of the most promising generic and condition-specific instruments. Methods A systematic review of the literature was performed to identify measures used in patients undergoing hip and knee replacement and extract and evaluate information on their methodological quality. Results Thirty-two shortlisted measures were reviewed for the quality of their measurement properties. On the basis of the review criteria, the measures with most complete evidence to date are the Oxford Hip Score (OHS) (for patients undergoing hip replacement surgery) and the Oxford Knee Score (OKS), with OKS-Activity and Participation Questionnaire (for patients undergoing knee replacement surgery). Conclusion A large number of these instruments lack essential evidence of their measurement properties (eg, validity, reliability, and responsiveness) in specific populations of patients. Further research is required on almost all of the identified measures. The best-performing condition-specific PROMs were the OKS, OHS, and Western Ontario and McMaster Universities Osteoarthritis Index. The best-performing generic measure was the Short Form 12. Researchers can use the information presented in this review to inform further psychometric studies of the reviewed measures. PMID:27524925

    A major decline in pulmonary function is observed on the first day after upper abdominal surgery. This decline can reduce vital and inspiratory capacity and can culminate in restrictive lung diseases that cause atelectasis, reduced diaphragm movement, and respiratory insufficiency. The objective of this study was to evaluate the efficacy of preoperative ambulatory respiratory muscle training in patients undergoing esophagectomy. The sample consisted of 20 adult patients (14 men [70%] and 6 women [30%]) with a diagnosis of advanced chagasic megaesophagus. A significant increase in maximum inspiratory pressure was observed after inspiratory muscle training when compared with baseline values (from −55.059 ± 18.359 to −76.286 ± 16.786). Preoperative ambulatory inspiratory muscle training was effective in increasing respiratory muscle strength in patients undergoing esophagectomy and contributed to the prevention of postoperative complications.

    Introduction 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. Objective To investigate the effect of inspiratory muscle training on functional capacity submaximal and inspiratory muscle strength in patients undergoing cardiac surgery. Methods 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. Results 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). Conclusion 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.

    Introduction: 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. Methods: 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. Results: 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). Conclusions: 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.

    Background. Obesity impacts utilization of healthcare resources. The goal of this study was to measure the relationship between increasing body mass index (BMI) in patients undergoing total hip arthroplasty (THA) with different components of operating room (OR) time. Methods. The Stanford Translational Research Integrated Database Environment (STRIDE) was utilized to identify all ASA PS 2 or 3 patients who underwent primary THA at Stanford Medical Center from February 1, 2008 through January 1, 2013. Patients were divided into five groups based on the BMI weight classification. Regression analysis was used to quantify relationships between BMI and the different components of total OR time. Results. 1,332 patients were included in the study. There were no statistically significant differences in age, gender, height, and ASA PS classification between the BMI groups. Normal-weight patients had a total OR time of 138.9 min compared 167.9 min (P < 0.001) for morbidly obese patients. At a BMI > 35 kg/m(2) each incremental BMI unit increase was associated with greater incremental total OR time increases. Conclusion. Morbidly obese patients required significantly more total OR time than normal-weight patients undergoing a THA procedure. This increase in time is relevant when scheduling obese patients for surgery and has an important impact on health resource utilization.

    Retention of {beta} 2-microglobulin in patients undergoing hemodialysis is associated with a {beta} 2-microglobulin-derived amyloidosis. Removal of {beta} 2-microglobulin by renal replacement therapy has been proposed for the prevention of this amyloidosis. Currently, however, data on the {beta} 2-microglobulin synthesis rate in patients undergoing hemodialysis are scarce, and consequently it remains speculative how much removal would be necessary to counterbalance synthesis. The plasma kinetics of iodine 131-labeled {beta} 2-microglobulin were therefore examined in 11 patients with anuria who were undergoing long-term hemodialysis. Five healthy persons served as controls. Kinetic modeling of the plasma curves showed that the data fitted a two-pool model (r2 greater than 0.96) consisting of a rapid 2 to 4 hour distribution phase followed by a less steep curve, described by the plasma (metabolic) clearance (Clp). Synthetic rates were calculated from Clp and the {beta} 2-microglobulin steady state plasma concentration (plus {beta} 2-microglobulin removal during hemodialysis in the case of high flux hemodialysis). The results showed a significantly higher Clp in normal controls as compared with patients undergoing hemodialysis (65.5 {plus minus} 12.8 ml/min (mean {plus minus} SD) versus 3.4 {plus minus} 0.7 ml/min). In contrast, the {beta} 2-microglobulin synthesis rate in the patient group (3.10 {plus minus} 0.79 mg/kg/day) was not significantly different from that of normal controls (2.40 {plus minus} 0.67 mg/kg/day), which was due to markedly elevated {beta} 2-microglobulin plasma concentrations in the patients (37.6 {plus minus} 14.1 mg/L vs 1.92 {plus minus} 0.27 mg/L). These findings suggest that the presence of end-stage renal disease does not have a significant impact on the beta 2-microglobulin generation rate.

    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.

    The management of suspected and/or unsuspected common bile duct (CBD) stones in patients undergoing laparoscopic cholecystectomy (LC) is controversial. Decisions on whether to perform an open CBD exploration versus employing therapeutic options such as preoperative/post-operative endoscopic retrograde cholangiography (ERCP) or endoscopic duct exploration are polemic. To determine indications, timing, benefits, and potential morbidity of these approaches, we gathered data on 401 patients undergoing LC within the last 18 months. Indications for preoperative ERCP included jaundice (40%), dilated ducts (28%), elevated amylase (19%) or alkaline phosphatase (21%), suspicion of CBD stones by ultrasound (17%) and "other" (17%). Indications for postoperative ERCP were retained stones (33%) and CBD evaluation (67%). Indications for CBD exploration included abnormal cholangiogram (64%), palpable stones (18%), and other (18%). A significant correlation was observed between suspected stones by ultrasound and stones found by ERCP (P < 0.01). For patients in the "other" category, preoperative ERCP was universally negative (P = 0.04). Overall ERCP morbidity was 4/59 (6.8%), and the overall failure rate for clearing CBD stones was 2/28 (7.1%). The timing of the ERCP did not affect morbidity/mortality. Multivariate analysis revealed that age (P < 0.001), the presence of pre-existing medical risk factors (P < 0.001), and duration of LC (P = 0.0034), but not ERCP (P = 0.08), were the important factors determining LC morbidity. In summary, common bile duct stones can be successfully cleared endoscopically in the majority of patients undergoing LC. Patients with suspected CBD stones should undergo pre-operative ERCP, and strict criteria should be applied in the selection of these patients.(ABSTRACT TRUNCATED AT 250 WORDS)

    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.

    Visceral disseminated varicella zoster virus (VZV) disease has a high mortality rate, and occurs in immunocompromised hosts, mostly subsequent to allogeneic stem cell transplantation. Only a few cases of this disease that onset during conventional chemotherapy in patients with lymphoma have been reported. The present study reports the cases of 3 patients with disseminated and visceral VZV infection undergoing treatment for follicular lymphoma, diffuse large B-cell lymphoma and peripheral T-cell lymphoma, not otherwise specified. All 3 patients presented with initial symptoms of abdominal pain, and 2 patients demonstrated syndrome of inappropriate antidiuretic hormone and hepatitis. All patients developed widespread cutaneous dissemination, and all had a low cluster of differentiation 4 cell count or lymphocyte count at the time of VZV diagnosis and at least 4 month prior. With intravenous systemic acyclovir therapy (Cases 1 and 3, 1500 mg/day; Case 2, 750 mg/day), the patients achieved complete recovery by day 14 of therapy. Visceral disseminated VZV infection is not limited to patients undergoing stem cell transplantation, and may present with abdominal pain with or without skin eruption. Visceral infection may take a poor clinical course, therefore, in patients with prolonged duration of low lymphocyte count and/or long-term use of steroids, the prophylactic use of acyclovir may be considered.

    Inadequate pain control in older patients who have undergone abdominal surgery can lead to many complications. This study investigates the effect of systematic relaxation techniques on pain and anxiety in older patients undergoing abdominal surgery. One hundred twenty-four patients were randomly assigned into the experimental and control groups. The systematic relaxation techniques consisted of older patients in the experimental group slowly reading relaxing sentences during recovery in ambulation after the surgery. Patients' satisfaction with pain and anxiety relief was recorded, as was their use of opioid analgesia. Statistically significant differences in pain and anxiety, and in analgesic use, were reported between the patients in experimental and control groups after the intervention. These relaxation techniques can be incorporated into the care plan to reduce pain and anxiety after surgery as well as offering a measure for increasing the patients' independence in pain management control.

    Electrolyte and mineral disturbances remain a major concern in patients undergoing continuous renal replacement therapy (CRRT); however, it is not clear whether those imbalances are associated with adverse outcomes in patients with septic acute kidney injury (AKI) undergoing CRRT. We conducted a post-hoc analysis of data from a prospective randomized controlled trial. A total of 210 patients with a mean age of 62.2 years (136 [64.8%] males) in 2 hospitals were enrolled. Levels of sodium, potassium, calcium, and phosphate measured before (0 hour) and 24 hours after CRRT initiation. Before starting CRRT, at least 1 deficiency and excess in electrolytes or minerals were observed in 126 (60.0%) and 188 (67.6%) patients, respectively. The excess in these parameters was greatly improved, whereas hypokalemia and hypophosphatemia became more prevalent at 24 hours after CRRT. However, 1 and 2 or more deficiencies in those parameters at the 2 time points were not associated with mortality. However, during 28 days, 89 (71.2%) deaths occurred in patients with phosphate levels at 0 hour of ≥4.5 mg/dL as compared with 49 (57.6%) in patients with phosphate levels <4.5 mg/dL. The 90-day mortality was also significantly higher in patients with hyperphosphatemia. Similarly, in 184 patients who survived at 24 hours after CRRT, hyperphosphatemia conferred a 2.2-fold and 2.6-fold increased risk of 28- and 90-day mortality, respectively. The results remained unaltered when the serum phosphate level was analyzed as a continuous variable. Electrolyte and mineral disturbances are common, and hyperphosphatemia may predict poor prognosis in septic AKI patients undergoing CRRT. PMID:27603344

    Implantation failure is a major limiting factor in assisted reproduction improvement. Dysfunction of embryo-maternal immuno-tolerance pathways may be responsible for repeated implantation failures. This fact is supported by immunotropic theory stipulating that maternal immune cells, essentially uterine CD56+ natural killer cells, are determinants of implantation success. In order to test this hypothesis, we applied endometrium immuno-modulation prior to fresh embryo transfer for patients with repeated implantation failures. Peripheral blood mononuclear cells were isolated from repeated implantation failure patients undergoing assisted reproductive technology cycles. On the day of ovulation induction, cells were isolated and then cultured for 3 days and transferred into the endometrium cavity prior to fresh embryo transfer. This immunotherapy was performed on 27 patients with repeated implantation failures and compared with another 27 patients who served as controls. Implantation and clinical pregnancy were increased significantly in the peripheral blood mononuclear cell test versus control (21.54, 44.44 vs. 8.62, 14.81%). This finding suggests a clear role for endometrium immuno-modulation and the inflammation process in implantation success. Our study showed the feasibility of intrauterine administration of autologous peripheral blood mononuclear cells as an effective therapy to improve clinical outcomes for patients with repeated implantation failures and who are undergoing in vitro fertilization cycles.

    An 80 year old woman developed fever 11 days after volvulus surgery. A peripheral blood smear showed numerous yeast cells--both extraleucocytic and intraleucocytic--as well as leucoagglutination. The fungal elements included blastospores, pseudohyphae, and germ tubes. Two days later, blood cultures yielded Candida albicans, Enterobacter aerogenes, and Staphlococcus aureus. The patient had no medical history of immunodeficiency. Several reports indicate that fungal elements may be detected in peripheral blood smears from patients who have a severe intestinal disease.

    Summary Background and objectives Patients with the hereditary disease Alport syndrome commonly require renal replacement therapy (RRT) in the second or third decade of life. This study compared age at onset of RRT, renal allograft, and patient survival in men with Alport syndrome receiving various forms of RRT (peritoneal dialysis, hemodialysis, or transplantation) with those of men with other renal diseases. Design, setting, participants, & measurements Patients with Alport syndrome receiving RRT identified from 14 registries in Europe were matched to patients with other renal diseases. A linear spline model was used to detect changes in the age at start of RRT over time. Kaplan-Meier method and Cox regression analysis were used to examine patient and graft survival. Results Age at start of RRT among patients with Alport syndrome remained stable during the 1990s but increased by 6 years between 2000–2004 and 2005–2009. Survival of patients with Alport syndrome requiring dialysis or transplantation did not change between 1990 and 2009. However, patients with Alport syndrome had better renal graft and patient survival than matched controls. Numbers of living-donor transplantations were lower in patients with Alport syndrome than in matched controls. Conclusions These data suggest that kidney failure in patients with Alport syndrome is now being delayed compared with previous decades. These patients appear to have superior patient survival while undergoing dialysis and superior patient and graft survival after deceased-donor kidney transplantation compared with patients receiving RRT because of other causes of kidney failure.

    The rapid progress in knee implants technology and operational techniques go together with more and more modem medical programs, designed to optimize the patients' care and shorten their stay in hospital. However, this does not guarantee any elimination ofperioperative stress in patients. Anxiety is a negative emotional state arising from stressful circumstances accompanied by activation of the autonomous nervous system. Anxiety causes negative physiological changes, including wound healing, resistance to anesthetic induction, it is associated with an increased perioperative pain and prolong recovery period. The purpose of this work is to present the current state of knowledge on the preoperative anxiety and discuss its impact on pain and other parameters in patients undergoing fast-track arthroplasty of big joints. The work also shows selected issues of anxiety pathomechanism, and actual methods reducing preoperative anxiety in hospitalized patients. The common prevalence of anxiety in patients undergoing surgery induces the attempt to routinely identify patients with higher anxiety, which may be a predictive factor of worse results after TKA. Undertaking widely understood psychological support in these patients before and after the operation could be a favorable element, which would influence thefinal result of the treatment of patients after big joints arthroplasties.

    Context Music and surgery. Objective To determine the effect of live classical piano music on vital signs of patients undergoing ophthalmic surgery. Design Retrospective case series. Setting and Patients 203 patients who underwent various ophthalmologic procedures in a period during which a piano was present in the operating room of St. Francis Medical Center. [Note: St. Francis Medical Center has recently been renamed Hawaii Medical Center East.] Intervention Demographic data, surgical procedures, and the vital signs of 203 patients who underwent ophthalmic procedures were obtained from patient records. Blood pressure, heart rate, and respiratory rate measured in the preoperative holding area were compared with the same parameters taken in the operating room, with and without exposure to live piano music. A paired t-test was used for statistical analysis. Main outcome measure Mean arterial pressure, heart rate, and respiratory rate. Results 115 patients who were exposed to live piano music showed a statistically significant decrease in mean arterial blood pressure, heart rate, and respiratory rate in the operating room compared with their vital signs measured in the preoperative holding area (P < .0001). The control group of 88 patients not exposed to live piano music showed a statistically significant increase in mean arterial blood pressure (P < .0002) and heart rate and respiratory rate (P < .0001). Conclusion Live classical piano music lowered the blood pressure, heart rate, and respiratory rate in patients undergoing ophthalmic surgery. PMID:18679538

    Changes in smoking behaviour and attitudes of 2642 patients, undergoing cardiac surgery, between January 2000 and July 2008 were studied. All patients completed a preoperative questionnaire concerning smoking behaviour and attitude. Study endpoints are behaviour and attitude in relation to tobacco use in hospitals, cessation smoking before and after the operation. Over the years there have been no notable differences in smoking behaviour, however, significantly less patients accept smoking in the hospital (0.9% vs. 5.3%). Significantly more patients stopped within the two weeks before surgery (9.4% vs. 5.3%). The percentage of patients who did not have the intention to stop smoking after the operation did not decrease significantly. Significantly less older patients smoke (1.6% vs. 13.4%) and are less tolerant towards smoking in the hospital (1.8% vs. 4.1%). A significant higher percentage of older patients have stopped smoking over five years before the operation. Concerning the intention to stop smoking after the operation, there is no significant difference. These results show that over the years, patients undergoing cardiac surgery seem to be more aware about the relation between health and smoking. This is not related to the type of operation, however, apparently with age.

    Meibomian gland dysfunction (MGD) is one of the most common conditions in the elderly. Most of MGD patients undergoing cataract surgery were found to have significant dry eye symptoms and ocular surface disease. The severe cases with ocular surface disease are also at higher risk of postoperative complications, namely infections and corneal ulcers. To improve the operation effect and achieve the best visual outcome and life quality in cataract patients, it is important to evaluate the ocular surface and meibomian glands in MGD patients preoperatively, pay attention to the intraoperative care and detect the postoperative complications carefully and use medicine properly.

    Isolated limb perfusion and isolated limb infusion are surgical interventions that provide high-dose regional chemotherapy to patients experiencing a recurrence of melanoma in an extremity. Nurses may be unfamiliar with these treatment options, as they are not available in all hospitals; however, the number of people diagnosed with melanoma is increasing. It is important for nurses to understand these surgical procedures to provide safe high-quality care before and after the surgery. Currently, there are several gaps in our knowledge about patients' experiences or nurse-sensitive outcomes. There are abundant opportunities for nurses to improve the care of patients who undergo surgical interventions to manage melanoma in the extremity.

    A strong emphasis on self-management for health maintenance in a variety of chronic diseases has been shown to benefit patients' outcomes and quality of life. However, little has been published on such programs in patients with chronic kidney disease. We studied the feasibility and effectiveness of the Chronic Disease Self-Management Program (CDSMP) in 14 patients with ESRD undergoing conventional hemodialysis. This program is designed to enhance skills in the areas of medical, emotional, and role management. Outcome measures in health status, self-management behaviors, self-efficacy, and health care utilization were evaluated through use of questionnaires at baseline and after six months. PMID:26263750

    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

    Coronary artery disease (CAD) is prevalent in patients with end-stage liver disease and associated with poor outcomes when undergoing orthotopic liver transplantation (OLT); however, noninvasive screening for CAD in this population is less sensitive. In an attempt to identify redundancy, we reviewed our experience among patients undergoing CAD screening as part of their OLT evaluation between May 2009 and February 2014. Demographic, clinical, and procedural characteristics were analyzed. Of the total number of screened patients (n = 132), initial screening was more common via stress testing (n = 100; 75.8%) than coronary angiography (n = 32; 24.2%). Most with initial stress testing underwent angiography (n = 52; 39.4%). Among those undergoing angiography, CAD was common (n = 31; 23.5%). Across the entire cohort the number of traditional risk factors was linearly associated with CAD, and those with two or more risk factors were found to have CAD by angiography 50% of the time (OR 1.92; CI 1.07-3.44, p = 0.026). Our data supports that CAD is prevalent among pre-OLT patients, especially among those with 2 or more risk factors. Moreover, we identified a lack of uniformity in practice and the need for evidence-based and standardized screening protocols. PMID:27418975

    Diabetes mellitus is associated with end-organ complications in the peripheral and central nervous system. It is unknown if these complications share a common aetiology, and if they co-occur in the same patient. The aim of the present study was to relate different measures of peripheral neuropathy in patients with type 2 diabetes mellitus (DM2) to cognition and brain MRI. A standardized neurological examination and questionnaire, neuropsychological examination and brain MRI were performed in 122 patients with DM2 and 56 matched controls. Measures of peripheral neuropathy were vibration threshold, a sensory examination sum score and the Toronto Clinical Neuropathy Scoring System. Neuropsychological test scores were expressed in standardized z-values across five predetermined cognitive domains. White matter lesions and cortical and subcortical atrophy were rated on MRI. Overall 38% of the patients with DM2 and 12% of the controls were classified as having any neuropathy (p<0.001). Patients with DM2 had a lower performance on the neuropsychological tests, more white matter lesions (p<0.01) and more atrophy (p<0.01) than controls. Within the DM2 group none of the measures of peripheral neuropathy was related to MRI abnormalities or cognitive dysfunction (linear regression analyses, adjusted for age, education, sex). We conclude that peripheral neuropathy in patients with DM2 is not related to cognitive dysfunction and brain abnormalities. This indicates that central and peripheral neurological complications of DM2 might have different etiologies.

    OBJECTIVE: To determine whether there is an association between serum ischemia-modified albumin and the risk factor profile in type 2 diabetic patients with peripheral arterial disease and to identify the risk markers for peripheral arterial disease. METHODS: Participants included 290 patients (35.2% women) with type 2 diabetes. The ankle-brachial pressure index was measured using a standard protocol, and peripheral arterial disease was defined as an ankle-brachial index <0.90 or ≥1.3. The basal ischemia-modified albumin levels and clinical parameters were measured and analyzed. The risk factors for peripheral arterial disease were examined by multiple logistic analyses. RESULTS: Age, systolic blood pressure, total cholesterol, low-density lipoprotein cholesterol, urine albumin, homocysteine, and ischemia-modified albumin were significantly higher in patients with peripheral arterial disease than in disease-free patients (p<0.05), while ankle-brachial index was lower in the former group (p<0.05). Ischemia-modified albumin was positively associated with HbA1c and homocysteine levels (r = 0.220, p = 0.030; r = 0.446, p = 0.044, respectively), while no correlation was found with ankle-brachial index. Multiple logistic analyses indicated that HbA1c, systolic blood pressure, homocysteine and ischemia-modified albumin were independent risk factors for peripheral arterial disease in the diabetic subjects. CONCLUSION: The baseline ischemia-modified albumin levels were significantly higher and positively associated with HbA1c and homocysteine levels in type 2 diabetic patients with peripheral arterial disease. Ischemia-modified albumin was a risk marker for peripheral arterial disease. Taken together, these results might be helpful for monitoring diabetic peripheral arterial disease. PMID:22012037

    Objective Evaluation of the functional outcomes of patients undergoing an early rehabilitation protocol for critically ill patients from admission to discharge from the intensive care unit. Methods A retrospective cross-sectional study was conducted that included 463 adult patients with clinical and/or surgical diagnosis undergoing an early rehabilitation protocol. The overall muscle strength was evaluated at admission to the intensive care unit using the Medical Research Council scale. Patients were allocated to one of four intervention plans according to the Medical Research Council score, the suitability of the plan’s parameters, and the increasing scale of the plan expressing improved functional status. Uncooperative patients were allocated to intervention plans based on their functional status. The overall muscle strength and/or functional status were reevaluated upon discharge from the intensive care unit by comparison between the Intervention Plans upon admission (Planinitial) and discharge (Planfinal). Patients were classified into three groups according to the improvement of their functional status or not: responsive 1 (Planfinal > Planinitial), responsive 2 (Planfinal = Planinitial) and unresponsive (Planfinal < Planinitial). Results In total, 432 (93.3%) of 463 patients undergoing the protocol responded positively to the intervention strategy, showing maintenance and/or improvement of the initial functional status. Clinical patients classified as unresponsive were older (74.3 ± 15.1 years of age; p = 0.03) and had longer lengths of intensive care unit (11.6 ± 14.2 days; p = 0.047) and hospital (34.5 ± 34.1 days; p = 0.002) stays. Conclusion The maintenance and/or improvement of the admission functional status were associated with shorter lengths of intensive care unit and hospital stays. The results suggest that the type of diagnosis, clinical or surgical, fails to define the positive response to an early rehabilitation protocol. PMID:26340157

    Background Unfulfilled expectations can lead to patient dissatisfaction with surgical outcomes. Understanding expectations allows surgeons to identify those patients who hold inaccurate expectations preoperatively, and to reset those expectations through focused pre-operative education. The purpose of this study is to investigate preoperative expectations of women undergoing implant breast reconstruction. Identifying inaccurate or unfulfilled expectations is a critical step towards the advancement of preoperative education and subsequently improving patient satisfaction with surgical outcomes. Methods In-depth, open-ended interviews were conducted with 28 women undergoing implant breast reconstruction. The interviews were recorded, transcribed, and data were coded using standard qualitative techniques. Results Interviews ascertained that implant-based breast reconstruction patients may have inaccurate expectations regarding the results of their surgery despite having received standard preoperative teaching. Specifically, patients often had unclear expectations regarding the appearance and physical outcome of the reconstructed breast(s). Some patients were surprised by the “flatness” of the tissue expander immediately following its insertion. Most patients felt unprepared for the “unnatural” final appearance of the breast(s). Furthermore, they did not expect many of the physical outcomes, including loss of sensation, firmness of the reconstructed breast(s), and lack of movement of the reconstructed breast(s). Inaccurate expectations corresponded to areas of dissatisfaction highlighted by the patients in postoperative interviews. Conclusion This study has important implications for preoperative education of women undergoing implant breast reconstruction. Physicians and nurses involved in the preoperative preparation process should take care to explore patients’ expectations regarding the look, feel, sensation, and movement of reconstructed breasts to

    Background Malnutrition is prevalent among peri-operative patients undergoing hepatobiliary surgery and is an important prognostic factor. Both hepatobiliary disease and surgical trauma significantly affects body’s metabolism and environment. Therefore, it is very important for patients with liver diseases undergoing hepatobiliary surgery to receive essential nutritional support during peri-operative period. Methods We summarized our clinical experience and reviewed of related literature to find the way for implementing the appropriate nutritional strategy. Results We found after comprehensively evaluating nutrition status, function of liver and gastrointestinal tract, nutritional strategy would be selected correctly. In severe malnutrition, initiation of enteral nutrition (EN) and/or parenteral nutrition (PN) with essential or special formulae is often recommended. Especially nasojejunal feeding is indicated that early application can improve nutritional status and liver function, reduce complications and prolong survival. Conclusions The reasonable peri-operative nutritional support therapy can improve the effect of surgical treatment and promote the patients’ recovery. PMID:26605277

    To better understand mannitol pharmacokinetics, the authors constructed and compared population models for high-versus low-dose bolus infusions in humans. Patients (aged 18-75, American Society of Anesthesiologists physical status 1-3) scheduled for elective craniotomy with an anticipated need for intraoperative mannitol were randomly assigned to receive either 0.5 (n = 10) or 1.0 (n = 12) g/kg of 20% mannitol over 15 minutes. Serial blood samples were collected at the predetermined intervals over 12 hours. Plasma mannitol concentrations were measured by gas chromatography and subjected to pharmacokinetic analysis; a 3-compartment model best described mannitol disposition characteristics. Weight and dose were the important covariates for rapid peripheral volume of distribution (V2) and central clearance (CL1), respectively. Estimated population means were 2.80, 8.86, and 12.0 L for central (V1), rapid (V2), and slow (V3) volumes of distribution, respectively. Clearances of the central compartments (CL1) were 0.07 versus 0.04 L/min in the high-versus low-dose group, respectively. Thus, mannitol kinetics can be considered as nonlinear. Clearances of the rapid peripheral (CL2) and slow peripheral compartments (CL3) were identical (2.07 and 0.16 L/min) in both. The current weight-based dosing guidelines yielded greater than expected plasma drug concentrations in obese patients. PMID:20051588

    A non-invasive method using continuous wave Doppler shift ultrasound and spectral analysis was used as a screening test for severe carotid artery disease in patients undergoing cardiopulmonary bypass operations. One hundred and eighty-eight patients were examined before cardiac surgery (91 for ischaemic heart disease, 17 for ischaemic heart disease and valve replacement, 66 for valve replacement alone, and 14 for congenital abnormalities). The mean age of the 108 patients suffering from ischaemic heart disease was 54 years (+/- 8) and that of the 80 patients admitted either for valve replacement alone or for congenital abnormalities was 52 years (+/- 12). Five of the 108 patients suffering from ischaemic heart disease were found to have severe occlusive disease of the internal carotid artery by the ultrasound test, while the test was normal in the other two groups. Patients with severe carotid artery disease proceeded to carotid arteriography and endarterectomy before the planned heart operation. Images PMID:7397042

    Background: In patients with advanced renal dysfunction undergoing maintenance hemodialysis, glycated albumin (GA) levels may be more representative of blood glucose levels than hemoglobin A1C levels. The aim of this study was to determine the predictive power of GA levels on long-term survival in hemodialysis patients. Methods: A total of 176 patients with a mean age of 68.2 years were enrolled. The median duration of follow-up was 51.0 months. Receiver-operating characteristic curve analysis was utilized to determine the optimal cutoff value. We examined the cumulative survival rate by Kaplan-Meier estimates and the influence of known survival factors with the multivariate Cox proportional-hazard regression model. Results: In the whole patient group, cumulative survival in the low GA group was better than in the high GA group (p=0.030), with more prominence in those aged <70 years (p=0.029). In subgroup analysis, both diabetic (DM) and non-DM patients with low GA had a better cumulative survival compared with those with high GA. The risk of mortality increased by 3.0% for each 1% increase in serum GA level in all patients undergoing hemodialysis. Conclusions: In addition to serving as a glycemic control marker, GA levels may be useful for evaluating the risk of death in both DM and non-DM patients on hemodialysis. PMID:27226780

    Background Postoperative delirium is a frequent complication in elderly patients undergoing major abdominal surgery and is associated with a poor outcome. We compared postoperative delirium in elderly patients following laparoscopic gastrectomy (LG) versus open gastrectomy (OG). Methods In total, 130 patients aged ≥ 65 years with gastric cancer undergoing LG and OG were enrolled prospectively. Postoperative delirium and cognitive status were assessed daily using the Confusion Assessment Method (CAM) and Mini-Mental Status Examination (MMSE), respectively, for 3 days postoperatively. For CAM-positive patients, delirium severity was then assessed using the Delirium Index (DI). Results In total, 123 subjects (LG, n = 60; OG, n = 63) were included in the analysis. In both groups, the overall incidences of postoperative delirium were similar: 31.6% (19/60) in the LG group and 41.2% (26/63) in the OG group. When considering only those with delirium, the severity, expressed as the highest DI score, was similar between the groups. A decline in cognitive function (reduction in MMSE ≥ 2 points from baseline) during 3 days postoperatively was observed in 23 patients in the LG group (38.3%) and 27 patients in the OG group (42.9%) (P = 0.744). In both groups, postoperative cognitive decline was significantly associated with postoperative delirium (P < 0.001). Conclusions We found that, compared with traditional open gastrectomy, laparoscopic gastrectomy did not reduce either postoperative delirium or cognitive decline in elderly patients with gastric cancer.

    A retrospective cohort study was performed to evaluate the relationship of BMI to conversion rate in patients undergoing robotic surgery for endometrial cancer. Secondary outcomes were operative times, number of lymph nodes retrieved, and complications. Women with endometrial cancer scheduled for robotic surgery from September 2008 to September 2012 were included. Women were divided into three groups based on BMI, and conversion rates to laparotomy were compared. Descriptive and comparative analyses were performed among non-obese, obese, and morbidly obese women who completed robotic surgery. 298 women were scheduled for robotic surgery for endometrial carcinoma: 87 non-obese (BMI 19-29, μ 25.23), 110 obese (BMI 30-39, μ 34.21), and 101 morbidly obese (BMI 40-71, μ 47.38). Conversion to laparotomy occurred in 18 patients (6%), with no difference in conversion rate between BMI categories. Direct comparison between converted and completed robotic patients showed no significant differences in preoperative characteristics, except that patients who required conversion had a higher number of previous abdominal surgeries. Patients completing robotic surgery underwent node dissections at similar rates in all three BMI categories. Operating room time, but not surgical time, was increased in morbidly obese patients. There were no significant differences in complications, performance of lymphadenectomy, or lymph node yields between BMI categories. Increase in BMI was not associated with an increase in rate of conversion to laparotomy or complication rate in patients undergoing robotic surgery for endometrial carcinoma. Node dissections were pathologically equivalent between BMI categories.

    The present study examines the reasons cited by 103 patients for their electing to undergo total knee arthroplastic surgery and the relationship between these reasons and their post-operative pain and range of motion. Results suggest that individuals who describe different reasons for undergoing surgery vary in their post-operative recovery. Specifically, patients who cite pain as the reason they are undergoing surgery report greater levels of pain during the early post-operative period. In contrast, patients who describe goals of regaining mobility or a specific activity as their reason for undergoing surgery achieve a greater range of motion during early post-operative physical therapy. Individuals who express avoidance goals for undergoing total knee arthroplasty report more severe post-operative pain at 1 and 3 months following surgery compared to patients who express approach goals. Interventions targeted towards patients reporting pre-operative pain or avoidance goals may decrease subsequent post-operative pain and increase mobility.

    Examination of 109 patients with chronic renal disease undergoing hemodialysis revealed significant impairment of arterial wall distensibility (accordingly, decreased Peterson's and Young's elastic moduli, distensibility coefficient). The relative thickness of the common carotid artery and pulse wave velocity were significantly greater than in practically healthy subjects. Independent factors influencing arterial wall rigidity included age, arterial pressure, total cholesterol and homocystein, stable metabolites of nitric oxide, creatinine, calcium, phosphorus levels, calcium x phosphorus product, duration of hemodialysis, interdialytic weight gain.

    Objective: The aim of the study was to assess the effect of dexmedetomidine in high-risk patients undergoing aortic vascular surgery. Design: A randomized prospective study. Setting: Cairo University, Egypt. Materials and Methods: The study included 150 patients undergoing aortic vascular surgery. Intervention: The patients were classified into two groups (n = 75). Group D: The patients received a loading dose of 1 μg/kg dexmedetomidine over 15 min before induction and maintained as an infusion of 0.3 μg/kg/h to the end of the procedure. Group C: The patients received an equal volume of normal saline. The medication was prepared by the nursing staff and given to anesthetist blindly. Measurements: The monitors included the heart rate, mean arterial blood pressure, central venous pressure, electrocardiogram (ECG), serum troponin I level, end-tidal sevoflurane, and total dose of morphine in addition transthoracic echocardiography to the postoperative in cases with elevated serum troponin I level. Main Results: The dexmedetomidine decreased heart rate and minimized the changes in blood pressure compared to control group (P < 0.05). Furthermore, it decreased the incidence of myocardial ischemia reflected by troponin I level, ECG changes, and the development of new regional wall motion abnormalities (P < 0.05). Dexmedetomidine decreased the requirement for nitroglycerin and norepinephrine compared to control group (P < 0.05). The incidence of hypotension and bradycardia was significantly higher with dexmedetomidine (P < 0.05). Conclusion: The dexmedetomidine is safe and effective in patients undergoing aortic vascular surgery. It decreases the changes in heart rate and blood pressure during the procedures. It provides cardiac protection in high-risk patients reflected by decreasing the incidence of myocardial ischemia and serum level of troponin. The main side effects of dexmedetomidine were hypotension and bradycardia. PMID:27716690

    Objective To determine whether cardiothoracic ratio (CTR), within the range conventionally considered normal, predicted prognosis in patients undergoing coronary angiography. Design Cohort study with a median of 7‐years follow‐up. Setting Consecutive patients undergoing coronary angiography at Barts and The London National Health Service (NHS) Trust. Subjects 1005 patients with CTRs measured by chest radiography, and who subsequently underwent coronary angiography. Of these patients, 7.3% had a CTR ⩾0.5 and were excluded from the analyses. Outcomes All‐cause mortality and coronary event (non‐fatal myocardial infarction or coronary death). Adjustments were made for age, left ventricular dysfunction, ACE inhibitor treatment, body mass index, number of diseased coronary vessels and past coronary artery bypass graft. Results The risk of death was increased among patients with a CTR in the upper part of the normal range. In total, 94 (18.9%) of those with a CTR below the median of 0.42 died compared with 120 (27.8%) of those with a CTR between 0.42 and 0.49 (log rank test p<0.001). After adjusting for potential confounders, this increased risk remained (adjusted HR 1.45, 95% CI 1.03 to 2.05). CTR, at values below 0.5, was linearly related to the risk of coronary event (test for trend p = 0.024). Conclusion : In patients undergoing coronary angiography, CTR between 0.42 and 0.49 was associated with higher mortality than in patients with smaller hearts. There was evidence of a continuous increase in risk with higher CTR. These findings, along with those in healthy populations, question the conventional textbook cut‐off point of ⩾0.5 being an abnormal CTR. PMID:17164481

  18. Clinical benefits of training patients to voluntarily increase peripheral blood flow: the WarmFeet intervention.

    Rice, Birgitta I

    2007-01-01

    The purpose of this article is to introduce a training program that can help diabetes educators get a fresh approach to assist their clients with the diabetes complication of limited peripheral blood flow. Biofeedback-assisted relaxation training is an educational and integrative intervention that supplements traditional medical care. Biofeedback-assisted relaxation training can be taught to the patient in a single setting. The relaxation training allows peripheral blood vessels to widen, providing enhanced circulation to peripheral tissues, including nerves. The training includes an explanation of relaxation and its effects on the patient, after which the technique is practiced with the assistance of thermal biofeedback. Biofeedback is an effective physiological training modality that teaches the patient what is going on in his or her own body. As the patient relaxes correctly, peripheral blood vessels dilate and blood flow improves, resulting in increased skin temperature. The change in skin temperature is measured with a small alcohol thermometer. Consistent relaxation yields significant outcomes such as improved peripheral blood flow, a reduction in peripheral pain, enhanced healing, improved ambulation, and increased coping skills in the patient's life.

    Current recommendations on the management of patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention with stent (PCI-S) essentially derive from small, single-center, retrospective datasets. To obtain larger and better quality data, we carried out the prospective, multicenter Atrial Fibrillation undergoing Coronary Artery Stenting (AFCAS) study. Therefore, consecutive patients with history of or ongoing AF undergoing PCI-S were enrolled, and occurrence of adverse ischemic and bleeding events recorded during 12 months follow-up. In this article, we report the in-hospital observations. Out of the 963 patients, in the majority of cases (49.1%) AF was permanent. The associated risk of stroke, as defined by a CHADS2 -score ≥2, was in 70% of patients moderate to high. Upon enrollment in the registry, 69.3% of patients were on VKA therapy. Overall occurrence of in-hospital major adverse cardiac events was 4.5% (cardiovascular death 1.9%, urgent revascularization in 1.5%, and stroke/arterial thromboembolism in 0.6%). Bleeding complications occurred in 7.1% of patients, being severe in 2.5%. In a logistic regression analysis, no risk factor was independently associated with bleeding events, whereas Clopidogrel treatment decreased and female gender/treatment with gpIIb/IIIa-antagonists, respectively increased the risk for the combined ischemic endpoint. The majority of AF patients undergoing PCI-S are at high stroke risk, and therefore VKA treatment should not be withdrawn and combined anticoagulant and antiplatelet treatment is warranted. Current management appears largely in accordance with current recommendations, whereby accounting for the limited occurrence of in-hospital adverse ischemic and bleeding events.

    Purpose: We have demonstrated that toxicities are acceptable with total marrow irradiation (TMI) at 16 Gy without chemotherapy or TMI at 12 Gy and the reduced intensity regimen of fludarabine/melphalan in patients undergoing hematopoietic cell transplantation (HCT). This article reports results of a study of TMI combined with higher intensity chemotherapy regimens in 2 phase I trials in patients with advanced acute myelogenous leukemia or acute lymphoblastic leukemia (AML/ALL) who would do poorly on standard intent-to-cure HCT regimens. Methods and Materials: Trial 1 consisted of TMI on Days -10 to -6, etoposide (VP16) on Day -5 (60 mg/kg), and cyclophosphamide (CY) on Day -3 (100 mg/kg). TMI dose was 12 (n=3 patients), 13.5 (n=3 patients), and 15 (n=6 patients) Gy at 1.5 Gy twice daily. Trial 2 consisted of busulfan (BU) on Days -12 to -8 (800 {mu}M min), TMI on Days -8 to -4, and VP16 on Day -3 (30 mg/kg). TMI dose was 12 (n=18) and 13.5 (n=2) Gy at 1.5 Gy twice daily. Results: Trial 1 had 12 patients with a median age of 33 years. Six patients had induction failures (IF), and 6 had first relapses (1RL), 9 with leukemia blast involvement of bone marrow ranging from 10%-98%, 5 with circulating blasts (24%-85%), and 2 with chloromas. No dose-limiting toxicities were observed. Eleven patients achieved complete remission at Day 30. With a median follow-up of 14.75 months, 5 patients remained in complete remission from 13.5-37.7 months. Trial 2 had 20 patients with a median age of 41 years. Thirteen patients had IF, and 5 had 1RL, 2 in second relapse, 19 with marrow blasts (3%-100%) and 13 with peripheral blasts (6%-63%). Grade 4 dose-limiting toxicities were seen at 13.5 Gy (stomatitis and hepatotoxicity). Stomatitis was the most frequent toxicity in both trials. Conclusions: TMI dose escalation to 15 Gy is possible when combined with CY/VP16 and is associated with acceptable toxicities and encouraging outcomes. TMI dose escalation is not possible with BU/VP16 due to

    Background and Purpose Selecting an ideal antithrombotic therapy for elderly patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) can be challenging since they have a higher thromboembolic and bleeding risk than younger patients. The current study aimed to assess the efficacy and safety of triple therapy (TT: oral anticoagulation plus dual antiplatelet therapy: aspirin plus clopidogrel) in patients ≥75 years of age with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI). Methods A prospective multicenter study was conducted from 2003 to 2012 at 6 Spanish teaching hospitals. A cohort study of consecutive patients with AF undergoing PCI and treated with TT or dual antiplatelet therapy (DAPT) was analyzed. All outcomes were evaluated at 1-year of follow-up. Results Five hundred and eighty-five patients, 289 (49%) of whom were ≥75 years of age (79.6±3.4 years; 33% women) were identified. TT was prescribed in 55.9% of patients at discharge who had a higher thromboembolic risk (CHA2DS2VASc score: 4.23±1.51 vs 3.76±1.40, p = 0.007 and a higher bleeding risk (HAS-BLED ≥3: 88.6% vs 79.2%, p = 0.02) than those on DAPT. Therefore, patients on TT had a lower rate of thromboembolism than those on DAPT (0.6% vs 6.9%, p = 0.004; HR 0.08, 95% CI: 0.01–0.70, p = 0.004). Major bleeding events occurred more frequently in patients on TT than in those on DAPT (11.7% vs 2.4%, p = 0.002; HR 5.2, 95% CI: 1.53–17.57, p = 0.008). The overall mortality rate was similar in both treatment groups (11.9% vs 13.9%, p = 0.38); however, after adjustment for confounding variables, TT was associated with a reduced mortality rate (HR 0.33, 95% CI: 0.12–0.86, p = 0.02). Conclusions In elderly patients with AF undergoing PCI, the use of TT compared to DAPT was associated with reduced thromboembolism and mortality rates, although a higher rate of major bleeding.

    Purpose and design The aim of this study was to establish the prevalence of known glaucoma in patients undergoing ectropion or entropion surgical repair. In this study, retrospective review of case series was performed. Participants All patients who underwent ectropion or entropion surgery in a tertiary medical center between 2007 and 2014 were included. The etiology of eyelid malpositioning was involutional or cicatricial. Methods The medical files of the study participants were reviewed for the presence and type of glaucoma, medical treatment, duration of treatment, and the amount of drops per day. These data were compared to a matched control group of 101 patients who underwent blepharoplasty for dermatochalasis in the same department during the same period. Main outcome measure In this study, the prevalence of glaucoma in individuals with ectropion or entropion was the main outcome measure. Results A total of 227 patients (57% men, mean age: 79.2 years) who underwent ectropion or entropion surgery comprised the study group and 101 patients who underwent upper blepharoplasty for dermatochalasis comprised the control group. Compared to four patients in the control group (4%, P=0.01), 30 of the study patients (13.2%) had coexisting glaucoma. Of 30 glaucomatous patients, 25 had primary open-angle glaucoma for a mean duration of 10.3 years. The glaucomatous patients were treated with an average of 2.7 antiglaucoma medications. Conclusion An increased prevalence of known glaucoma in patients undergoing ectropion or entropion repair surgery was found. This observation may indicate that the chronic usage of topical anti-glaucoma eyedrops may lead to an increased risk of developing eyelid malpositions, especially in elderly patients. PMID:27785003

    Hepatitis C infection is a worldwide problem. The global prevalence of the hepatitis C virus (HCV) averages 3%. Moreover, its prevalence among patients undergoing haemodialysis (HD) varies worldwide, ranging from as low as 1% to up to 70%. There are few data on its prevalence in developing countries, and even less information is available on HD patients. A literature review revealed that the prevalence of HCV infection among patients undergoing HD in Latin America ranges from 4.2 to 83.9%, with most data stemming from Argentina, Brazil, Mexico, Peru, Chile, Venezuela and Cuba. The most common genotype was genotype 1, and subtype 1b was the most frequent. The risk factors associated with this condition were the duration of the HD treatment and blood transfusion before hepatitis C screening. In addition, HCV RNA detection by polymerase chain reaction is crucial for the diagnosis of HCV infection in HD patients. Trials using combinations of new oral antiviral drugs, such as sofosbuvir and combo (ombitasvir, paritaprevir, ritonavir and dasabuvir), should be the next step in the improvement of care among HD patients with HCV, because these therapeutic agents apparently do not require dose adjustment according to renal function. Finally, information on this subgroup of patients remains unavailable in some countries; therefore, additional studies are needed to determine the prevalence trend of HCV infection in these populations.

    Peripherally inserted central venous catheters (PICCs) are of growing interest because they allow intravenous therapies up to several months. The appropriate management of the PICCs is crucial to minimize complications and largely depends on the right information for everyone who cares for the patient. To reach this goal we develop the mobile application "PICC App" to provide the necessary information for all involved persons in the outpatient setting. We expect to be able to report about the PICC App and the results of the usability evaluation with pilot users.

    AIM: To investigate possible disparities in perioperative morbidity and mortality among different body mass index (BMI) groups and to simulate the impact that these differences might have had on the cohort of patients undergoing cadaveric liver transplantation (LT). METHODS: All adult recipients undergoing first time LT for benign conditions and receiving a whole graft from brain-dead donors were selected from the united network of organ sharing registry. From January 1994 to June 2013, 48281 patients satisfied the inclusion criteria and were stratified by their BMI. The hypothesis that abnormal BMIs were independent predictors of inferior outcomes was tested with univariate and multivariate regression analyses. RESULTS: In comparison to normal weight recipients, underweight and morbidly obese recipients had increased 90-d mortality (adjusted OR = 1.737; 95%CI: 1.185-2.548, P = 0.005) (adjusted OR = 1.956; 95%CI: 1.473-2.597, P = 0.000) respectively and inferior patients’ survivals (adjusted HR = 1.265; 95%CI: 1.096-1.461, P = 0.000) (adjusted HR = 1.157; 95%CI: 1.031-1.299, P = 0.013) respectively. Overall, patients’ 5-year survival were 73.9% for normal-weight, 71.1% for underweight, 74.0% for overweight, 74.4% for class I obese, 75.0% for class II obese and 71.5% for class III obese recipients. Analysis of hypothetical exclusion of underweight and morbidly obese patients from the pool of potential LT candidates would have improved the overall survival of the entire cohort by 2.7% (95%CI: 2.5%-3.6%). CONCLUSION: Selected morbidly obese patients undergoing LT for benign conditions had 5-year survival rates clinically comparable to normal weight recipients. Impact analysis showed that exclusion of high-risk recipients (underweight and morbid obese patients) would not significantly improve the overall survival of the entire cohort of patients requiring LT.

    Emergency laparotomies are performed commonly throughout the world, but one in six patients die within a month of surgery. Current international initiatives to reduce the considerable associated morbidity and mortality are founded upon delivering individualised perioperative care. However, while the identification of high-risk patients requires the routine assessment of individual risk, no method of doing so has been demonstrated to be practical and reliable across the commonly encountered spectrum of presentations, co-morbidities and operative procedures. A systematic review of Embase and Medline identified 20 validation studies assessing 25 risk assessment tools in patients undergoing emergency laparotomy. The most frequently studied general tools were APACHE II, ASA-PS and P-POSSUM. Comparative, quantitative analysis of tool performance was not feasible due to the heterogeneity of study design, poor reporting and infrequent within-study statistical comparison of tool performance. Reporting of calibration was notably absent in many prognostic tool validation studies. APACHE II demonstrated the most consistent discrimination of individual outcome across a variety of patient groups undergoing emergency laparotomy when used either preoperatively or postoperatively (area under the curve 0.76-0.98). While APACHE systems were designed for use in critical care, the ability of APACHE II to generate individual risk estimates from objective, exclusively preoperative data items may lead to better-informed shared decisions, triage and perioperative management of patients undergoing emergency laparotomy. Future endeavours should include the recalibration of APACHE II and P-POSSUM in contemporary cohorts, modifications to enable prediction of morbidity and assessment of the impact of adoption of these tools on clinical practice and patient outcomes.

    Purpose: To identify factors impacting outcome in patients undergoing interventions for acute ischemic stroke (AIS). Materials and Methods: This was a retrospective analysis of patients undergoing endovascular therapy for AIS secondary during a 30 month period. Outcome was based on modified Rankin score at 3- to 6-month follow-up. Recanalization was defined as Thrombolysis in myocardial infarction score 2 to 3. Collaterals were graded based on pial circulation from the anterior cerebral artery either from an ipsilateral injection in cases of middle cerebral artery (MCA) occlusion or contralateral injection for internal carotid artery terminus (ICA) occlusion as follows: no collaterals (grade 0), some collaterals with retrograde opacification of the distal MCA territory (grade 1), and good collaterals with filling of the proximal MCA (M2) branches or retrograde opacification up to the occlusion site (grade 2). Occlusion site was divided into group 1 (ICA), group 2 (MCA with or without contiguous M2 involvement), and group 3 (isolated M2 or M3 branch occlusion). Results: A total of 89 patients were studied. Median age and National Institutes of health stroke scale (NIHSS) score was 71 and 15 years, respectively. Favorable outcome was seen in 49.4% of patients and mortality in 25.8% of patients. Younger age (P = 0.006), lower baseline NIHSS score (P = 0.001), successful recanalization (P < 0.0001), collateral support (P = 0.0008), distal occlusion (P = 0.001), and shorter procedure duration (P = 0.01) were associated with a favorable outcome. Factors affecting successful recanalization included younger age (P = 0.01), lower baseline NIHSS score (P = 0.05), collateral support (P = 0.01), and shorter procedure duration (P = 0.03). An ICA terminus occlusion (P < 0.0001), lack of collaterals (P = 0.0003), and unsuccessful recanalization (P = 0.005) were significantly associated with mortality. Conclusion: Angiographic findings and preprocedure variables can help

    Study Design Retrospective database analysis. Objective To assess the effect glycemic control has on perioperative morbidity and mortality in patients undergoing elective degenerative lumbar spine surgery. Summary of background data Diabetes Mellitus (DM) is a prevalent disease of glucose dysregulation that has been demonstrated to increase morbidity and mortality following spine surgery. However, there is limited understanding of whether glycemic control influences surgical outcomes in DM patients undergoing lumbar spine procedures for degenerative conditions. Methods The Nationwide Inpatient Sample was analyzed from 2002 to 2011. Hospitalizations were isolated based on International Classification of Diseases Ninth Revision, Clinical Modification procedural codes for lumbar spine surgery and diagnoses codes for degenerative conditions of the lumbar spine. Patients were then classified into three cohorts: controlled diabetics, uncontrolled diabetics and non-diabetics. Patient demographic data, acute complications and hospitalization outcomes were determined for each cohort. Results A total of 403,629 (15.7%) controlled diabetics and 19,421(0.75%) uncontrolled diabetics underwent degenerative lumbar spine surgery from 2002-2011. Relative to non-diabetics, uncontrolled diabetics had significantly increased odds of cardiac complications, deep venous thrombosis and post-operative shock; additionally, uncontrolled diabetics also had an increased mean length of stay (approximately 2.5 days), greater costs (1.3-fold) and a greater risk of inpatient mortality (odds ratio=2.6, 95% confidence interval=1.5-4.8, p < .0009). Controlled diabetics also had increased risk of acute complications and inpatient mortality when compared to non-diabetics, but not nearly to the same magnitude as uncontrolled diabetics. Conclusion Suboptimal glycemic control in diabetic patients undergoing degenerative lumbar spine surgery leads to increased risk of acute complications and poor outcomes

    Clinical practice sometimes brings to face with situations quite peculiar, potentially dangerous for the patient's life. In the great majority of cases, pathologies associated with each other (cardiovascular, respiratory, neurological), while in other cases we can treat rare diseases or syndromes. It's considered exceptional the simultaneous presence of "rare" pathologies in a single patient. This exceptionality has been a push to treat a patient as a "unique" asking for help to deeper studies of pharmacogenetics. Our case reports the management of a patient with Ehlers-Danlos syndrome (EDS) and Multiple Chemical Sensitivity (MCS), undergoing a total thyroidectomy. We found several problems, and we tried to find effective solutions for the management of the patient during the whole peri-operative process, from a clinical, pharmacological and also from a surgical point of view.

Tamoxifen has been generally well-tolerated, even without randomized controlled trials. Case Presentation Herein, we report a case of a patient undergoing 12 years of PD who developed EPS and calciphylaxis simultaneously. We also provide a comprehensive discussion about the association between EPS and calciphylaxis. Moreover, although tamoxifen is used in EPS due to its inhibition of fibroblast-transforming growth factor beta (TGFβ) production, it may worsen the calciphylaxis due to a hypercoagulable state. Conclusions We suggest avoiding the use of tamoxifen for EPS in patients with superimposed calciphylaxis.

    The esophagectomy for esophageal cancer is major surgery and has the highest rate of postoperative pulmonary complications. Respiratory physiotherapy in patients undergoing esophagectomy has been applied to improve oxygenation and airway secretion clearance. Recently, the utility and effectiveness of enhanced recovery after surgery for gastroenterological surgery have been reported in Japan, and patients should be encouraged to participate in early mobilization. Perioperative rehabilitation which includes early mobilization reduces postoperative complications and improves fast-track recovery after esophagectomy. These interventions play important role in postoperative care. PMID:26975645

    Hypertrophic cardiomyopathy (HCM) presents a significant perioperative challenge. Anesthetic drugs, patient positioning, and surgical technique can provoke worsening left ventricular outflow tract obstruction and hemodynamic deterioration. In this case report, we present the perioperative management of a 70-year-old male with a history of HCM who underwent a robotic laparoscopic prostatectomy. Discussion focuses on the utilization of echocardiographic guidance in the care of patients with HCM undergoing noncardiac surgery, as well as the pathophysiology of laparoscopic insufflation and its effects on left ventricular outflow tract obstruction in HCM.

    Excision of a suspected retroperitoneal, duodenal duplication cyst was performed in a pre-operatively normotensive patient under combined epidural and general anaesthesia. Intraoperatively, the cystic tumour was discovered to be a retroperitoneal mass, free from duodenal or adrenal origin. Development of severe arrhythmias, ST segment changes and hypertensive spikes during cyst handling and dissection suggested the possibility of a catecholamine-secreting tumour. These were managed effectively with pharmacological agents. Subsequently, histopathology of the specimen revealed a paraganglioma. Vasoactive tumour has to be suspected in every patient undergoing anaesthesia for retroperitoneal cystic lesion.

    Patients with peripheral vascular disease have a high risk of coronary artery disease. The risk is even greater when the peripheral vascular disease leads to lower extremity amputation. Exercise testing using lower extremity exercise has been the "gold standard" for screening for coronary artery disease, but many patients with peripheral vascular disease and those with amputations have difficulty doing this type of exercise. Arm exercise ergometry has been shown to be a safe and effective alternative for the detection of coronary artery disease in patients who cannot do leg exercise. This test has also been used to determine safe exercise levels and may be able to predict the ultimate level of prosthetic use in amputees. Exercise training with arm ergometry also improves cardiovascular efficiency and upper body strength in poorly conditioned patients. Studies are needed to appreciate fully the role of exercise testing and training in the recovery of these patients after amputation. PMID:1866958

    Prognostic value of peripheral monocyte, as a member of inflammatory cells, was widely being investigated. The aim of this study was to evaluate the prognostic value of preoperative peripheral blood monocyte count for hepatocellular carcinoma (HCC) patients who underwent liver transplantation (LT) and the relationship between monocyte count and tumor-related characteristics. We retrospectively analyzed the clinical data of 101 HCC patients after LT. Preoperative monocyte count and demographic, clinical, and pathologic data were analyzed. The optimal cutoff value of monocyte count was 456/mm(3), with the sensitivity and specificity of 69.4 and 61.5 %, respectively. Elevated preoperative peripheral blood monocyte count was significantly associated with large tumor size. The 1-, 3-, and 5-year disease-free survival (DFS) (80.9, 70.1, and 53.3 % vs 55.1, 38.7, and 38.7 %, P = 0.007) and overall survival (OS) rates (95.7, 76.6, and 64.8 % vs 72.2, 44.1, and 36.1 %, P = 0.002) of HCC patients in the peripheral blood monocyte count ≤456/mm(3) group were higher than those in the peripheral blood monocyte count >456/mm(3) group. In conclusion, elevated preoperative peripheral blood monocyte count was significantly associated with advanced tumor stage and it can be considered as a prognostic factor for HCC patients after LT.

    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.

    We investigated the effect of high spinal anesthesia on postoperative delirium in opium dependent patients undergoing coronary artery bypass grafting (CABG). The study was conducted in a tertiary referral university hospital on a population of 60 opium dependent patients undergoing CABG surgery. Patients were divided into two groups based on anesthesia protocol. One group were given general anesthesia (GA Group), the other group additionally received intrathecal morphine and bupivacaine (SGA Group). Postoperative delirium (POD) was defined as the main outcome of interest. Incidence of POD was significantly higher in patients of GA Group as compared with those in SGA Group (47% and 17% for GA and SGA respectively; P-value = 0.01). Time to extubation was on average 2.2 h shorter in SGA than in GA (7.1 h and 9.3 h respectively, P-value < 0.001). Intrathecal morphine and bupivacaine reduced the risk of POD after CABG in a population of opium dependent patients.

    In six patients with end-stage renal disease, a single bolus of imipenem-cilastatin (500 mg each) was given either intravenously or intraperitoneally in a randomized crossover protocol such that each patient received the drug by both routes at a 2- to 3-week interval. Drug levels in plasma and the peritoneal dialysis fluid were analyzed at frequent intervals, and various pharmacokinetic variables were calculated for a one-compartment open model. Data obtained in the present study suggest that while no significant difference in peak plasma levels or volume of distribution were noted, the following variables were significantly different for imipenem as compared with cilastatin: elimination half-life, total plasma clearance, area under the concentration-time curve, and percent drug excretion in the peritoneal dialysis fluid. The elimination half-life of imipenem (3.28 h) or cilastatin (8.84 h) in our patients was in the same range as observed in patients with minimal renal function undergoing hemodialysis. The dose of imipenem-cilastatin should be reduced appropriately in patients with end-stage renal disease undergoing peritoneal dialysis. PMID:3377464

    Red blood cell distribution width (RDW), which is routinely reported in complete blood counts, is a measure of the variability in size of circulating erythrocytes. RDW is a novel, independent predictor of prognosis in patients with cardiovascular diseases. The aim of the present study was to evaluate the significance of this biomarker in a relatively large cohort of patients, and to assess its association with a more severe underlying cardiovascular disease. A cohort of 3,222 consecutive patients undergoing coronary angiography was divided according RDW median. The association between RDW and 3-year outcome in the context of other predictors was assessed using Cox's proportional hazards analysis. Patients with elevated RDWs were older, had higher body mass indices, and had more cardiovascular risk factors and more cardiovascular diseases. The total rate of mortality, MI and stroke (MACE) was 7.7% (120 events) in the lower RDW group, and 18.2% (303 events) in the higher RDW group, p < 0.001. Following adjustment for multiple background risk factors, medications, and laboratory results, the RDW value was independently associated with worse outcome (HR = 1.12, 95% CI 1.07-1.18, p < 0.001, for each 1% increase in RDW). Elevated RDW values are independently associated with adverse 3-year outcome in patients undergoing coronary angiography. PMID:23836454

    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.

    INTRODUCTION Music has been proposed as a safe, inexpensive, nonpharmacological antistress intervention. The purpose of this study was to determine whether patients undergoing cataract surgery while listening to meditation music experience lower levels of blood pressure and heart rate. METHODS Two hundred individuals undergoing cataract surgery participated in the study. Hundred individuals listened to meditation music, through headphones, before and during the operation (intervention group) and 100 individuals received standard care (control group). Patients stress coping skills were measured by the Sense of Coherence Scale (SOC Scale). Systolic and diastolic blood pressure and heart rate were defined as outcome measures. RESULTS According to the SOC Scale, both groups had similar stress coping skills (mean score: 127.6 for the intervention group and 127.3 for the control group). Before entering the operating room (OR) as well as during surgery the rise in systolic and diastolic pressures was significantly lower in the intervention group (P < 0.001). Among patients receiving antihypertensive therapy, those in the intervention group presented a lower increase only in systolic pressure (P < 0.001) at both time recordings. For those patients in the intervention group who did not receive antihypertensive treatment, lower systolic blood pressure at both time recordings was recorded (P < 0.001) while lower diastolic pressure was observed only during entry to the OR (P = 0.021). Heart rate was not altered between the two groups in any of the recordings. CONCLUSIONS Meditation music influenced patients’ preoperative stress with regard to systolic blood pressure. This kind of music can be used as an alternative or complementary method for blood pressure stabilizing in patients undergoing cataract surgery. PMID:26106264

    Background Prior studies have suggested intraaortic balloon pump (IABP) have a neutral effect on acute myocardial infarction (AMI) patients with cardiogenic shock (CS). However, the effects of IABP on patients with severe CS remain unclear. We therefore investigated the benefits of IABP in AMI patients with severe CS undergoing coronary revascularization. Methods and Results This study identified 14,088 adult patients with AMI and severe CS undergoing coronary revascularization from Taiwan’s National Health Insurance Research Database between January 1, 1997 and December 31, 2011, dividing them into the IABP group (n = 7044) and the Nonusers group (n = 7044) after propensity score matching to equalize confounding variables. The primary outcomes included myocardial infarction(MI), cerebrovascular accidents or cardiovascular death. In-hospital events including dialysis, stroke, pneumonia and sepsis were secondary outcomes. Primary outcomes were worse in the IABP group than in the Nonusers group in 1 month (Hazard ratio (HR) = 1.97, 95% confidence interval (CI) = 1.84–2.12). The MI rate was higher in the IABP group (HR = 1.44, 95% CI = 1.16–1.79), and the cardiovascular death was much higher in the IABP group (HR = 2.07, 95% CI = 1.92–2.23). The IABP users had lower incidence of dialysis (8.5% and 9.5%, P = 0.04), stroke (2.6% and 3.8%, P<0.001), pneumonia (13.9% and 16.5%, P<0.001) and sepsis (13.2% and 16%, P<0.001) during hospitalization than Nonusers. Conclusion The use of IABP in patients with myocardial infarction and severe cardiogenic shock undergoing coronary revascularization did not improve the outcomes of recurrent myocardial infarction and cardiovascular death. However, it did reduce the incidence of dialysis, stroke, pneumonia and sepsis during hospitalization. PMID:27483439

    Introduction Treatment of cholesteatoma consists of either excision or exteriorisation of disease. Approaches have traditionally included a radical or modified radical mastoidectomy and combined approach tympanoplasty. Hearing thresholds following a modified radical mastoidectomy alone have been reported as poor. We assessed hearing outcomes in patients undergoing a primary malleostapedial reconstruction combined with their open cavity surgery. Methods All patients undergoing open cavity mastoidectomy with primary malleostapedial rotation ossiculoplasty between 2009 and 2013 were identified. Case notes were reviewed, and demographic data, recurrence rate and audiometry were recorded. Results Twenty-one patients were identified. The age range was 10–65 years. There was no evidence of recurrence of cholesteatoma. The mean postoperative air-bone gap was 20dBHL, 23dBHL, 10dBHL and 27dBHL at 0.5kHz, 1kHz, 2kHz and 4kHz respectively. Excluding cases consistent with a postoperative ossicular discontinuity (n=3), the mean postoperative air-bone gap was 15dBHL, 19dBHL, 8dBHL and 26dBHL at 0.5kHz, 1kHz, 2kHz and 4kHz respectively. Conclusions The improvement in hearing thresholds demonstrated in this cohort of patients supports the use of this form of ossiculoplasty in those undergoing open cavity procedures. This would also suggest that the subsequent use of hearing aids in these patients would require less amplification and therefore provide superior hearing outcomes. As hearing loss remains a significant concern following modified radical mastoidectomy, we suggest an open cavity with primary malleostapedial rotation ossiculoplasty as a viable alternative to modified radical mastoidectomy alone, in selected cases.

    Whether low-concentration desflurane reinforces propofol-based intravenous anesthesia on maintenance of anesthesia for patients undergoing laparoscopic cholecystectomy is to be determined. The aim of this study was to investigate whether propofol-based anesthesia adding low-concentration desflurane is feasible for laparoscopic cholecystectomy. Fifty-two patients undergoing laparoscopic cholecystectomy were enrolled in the prospective, randomized, clinical trial. Induction of anesthesia was achieved in all patients with fentanyl 2 μg/kg, lidocaine 1 mg/kg, propofol 2 mg/kg, and rocuronium 0.8 mg/kg to facilitate tracheal intubation and to initiate propofol target-controlled infusion (TCI) to effect site concentration (Ce: 4 μg/mL with infusion rate 400 mL/h). The patients were then allocated into either propofol TCI based (group P) or propofol TCI adding low-concentration desflurane (group PD) for maintenance of anesthesia. The peri-anesthesia hemodynamic responses to stimuli were measured. The perioperative psychomotor test included p-deletion test, minus calculation, orientation, and alert/sedation scales. Group PD showed stable hemodynamic responses at CO2 inflation, initial 15 minutes of operation, and recovery from general anesthesia as compared with group P. There is no significant difference between the groups in operation time and anesthesia time, perioperative psychomotor functional tests, postoperative vomiting, and pain score. Based on our findings, the anesthetic technique combination propofol and desflurane for the maintenance of general anesthesia for laparoscopic cholecystectomy provided more stable hemodynamic responses than propofol alone. The combined regimen is recommended for patients undergoing laparoscopic cholecystectomy.

    Background Health-related quality of life (HRQOL) reflects the general well-being of individuals. In patients with coronary artery disease (CAD), HRQOL is compromised. Female patients with CAD have been reported to have lower HRQOL. In this study, we investigate gender differences in HRQOL and in associations of patient characteristics with HRQOL in patients with coronary angiography (CAG). Methods We cross-sectionally analysed patients from the Utrecht Coronary Biobank undergoing CAG. All patients filled in an HRQOL questionnaire (RAND-36 and EuroQoL) on inclusion. RAND-36 and EuroQoL HRQOL measures were compared between the genders across indications for CAG, CAD severity and treatment of CAD. RAND-36 HRQOL measures were compared with the general Dutch population. Additionally, we assessed interactions of gender with patient characteristics in their association with HRQOL (EuroQoL). Results We included 1421 patients (1020 men and 401 women) with a mean age of 65 in our analysis. Women reported lower HRQOL measures than men (mean EuroQoL self-rated health grade 6.84±1.49 in men, 6.46±1.40 in women, p<0.001). The reduction in RAND-36 HRQOL as compared with the general Dutch population was larger in women than in men. From regression analysis, we found that diabetes, a history of cardiovascular disease and symptoms of shortness of breath determined HRQOL (EuroQoL) more strongly in men than in women. Conclusions Women reported lower HRQOL than men throughout all indications for CAG and regardless of CAD severity or treatment. As compared with the general population, the reduction in HRQOL was more extreme in women than in men. Evident gender differences were found in determinants of HRQOL in patients undergoing CAG, which deserve attention in future research. Trial registration NCT02304744 (clinicaltrials.gov).

    OBJECTIVES: We sought to develop and validate a model that estimates the risk of obstructive coronary artery disease in patients undergoing operations for mitral valve degeneration and to demonstrate its potential clinical utility. METHODS: A total of 722 patients (67% men; age, 61 +/- 12 years) without a history of myocardial infarction, ischemic electrocardiographic changes, or angina who underwent routine coronary angiography before mitral valve prolapse operations between 1989 and 1996 were analyzed. A bootstrap-validated logistic regression model on the basis of clinical risk factors was developed to identify low-risk (< or =5%) patients. Obstructive coronary atherosclerosis was defined as 50% or more luminal narrowing in one or more major epicardial vessels, as determined by means of coronary angiography. RESULTS: One hundred thirty-nine (19%) patients had obstructive coronary atherosclerosis. Independent predictors of coronary artery disease include age, male sex, hypertension, diabetes mellitus,and hyperlipidemia. Two hundred twenty patients were designated as low risk according to the logistic model. Of these patients, only 3 (1.3%) had single-vessel disease, and none had multivessel disease. The model showed good discrimination, with an area under the receiver-operating characteristic curve of 0.84. Cost analysis indicated that application of this model could safely eliminate 30% of coronary angiograms, corresponding to cost savings of $430,000 per 1000 patients without missing any case of high-risk coronary artery disease. CONCLUSION: A model with standard clinical predictors can reliably estimate the prevalence of obstructive coronary atherosclerosis in patients undergoing mitral valve prolapse operations. This model can identify low-risk patients in whom routine preoperative angiography may be safely avoided.

    Systemic sclerosis (SSc) is characterized by disturbed blood circulation. The effect of ambrisentan, an endothelin-A receptor-selective antagonist, on impaired peripheral circulation in SSc remains largely elusive. Here we show SSc patients, whose clinical symptoms such as cyanosis and Raynaud's phenomenon, were ameliorated by the treatment with ambrisentan. Additionally, objective evaluations with thermography showed improvement of hand coldness in steady-state and cold challenge tests. Ambrisentan might have a potential to improve peripheral circulation in SSc.

    Cytogenetics play a major role in determining the prognosis of patients with AML. However, the existing cytogenetics classifications were developed on chemotherapy-treated patients and may not be optimal for patients undergoing allogeneic hematopoietic cell transplantation (HCT). We studied 821 adult patients reported to the CIBMTR who underwent HCT for AML in first or second CR between 1999 and 2004. We compared the ability of the 6 existing classifications to stratify patients by overall survival (OS). We then defined a new schema specifically applicable to HCT patients using this patient cohort. Under this CIBMTR schema, inv(16) is favorable, complex karyotype (4+ abnormalities) is adverse, and all other classified abnormalities are intermediate in predicting survival after HCT (5y OS 64%, 18%, and 50%, respectively, p=0.0001). This schema stratified patients into 3 groups with similar non-relapse mortality, but significantly different incidences of relapse, overall and leukemia-free survival. It applied to patients regardless of their disease status (CR1 or CR2), donor type (MRD or URD), or conditioning intensity (myeloablative or reduced intensity). This transplantation-specific classification could be adopted for prognostication purposes and to stratify patients with AML and karyotypic abnormalities entering HCT clinical trials. PMID:21810400

    Haploidentical SCT (HaploSCT) has been most commonly performed using a myeloablative, TBI-based preparative regimen; however, the toxicity with this approach remains very high. We studied the feasibility of a reduced-intensity conditioning regimen in a phase II clinical trial using fludarabine, melphalan and thiotepa and antithymocyte globulin (ATG) for patients with advanced hematological malignancies undergoing T-cell depleted HaploSCT. Twenty-eight patients were entered in the study. Engraftment with donor-derived hematopoiesis was achieved in 78% of patients after a median of 13 days. Six patients experienced primary graft failure, three out of four tested patients had donor-specific anti-HLA antibodies (DSA) (P = 0.001). Toxicity included mostly infections. A total of 21 out of 22 patients with AML/myelodysplastic syndrome (MDS) achieved remission after transplant (16 with relapsed/refractory AML). Five out of the 12 patients (42%) with AML/MDS with <15% BM blasts survived long term as compared with none with more advanced disease (P = 0.03). HaploSCT with this fludarabine, melphalan and thiotepa and ATG RIC is an effective, well-tolerated conditioning regimen for patients with AML/MDS with low disease burden at the time of transplant and allowed a high rate of engraftment in patients without DSA. Patients with overt relapse fared poorly and require novel treatment strategies. PMID:19668237

    Some patients undergoing periodic hemodialysis have complained that between one treatment session and the next they suffer form thirst and have serious problems in maintaining their interdialytic weight gain within the limits indicated by the medical team. Weight gain may usually be explained by psychological factors: they may be more or less acute depending on the situation in which the patient finds himself. On the basis of the present study, the Authors affirm that the lack of interdialytic weight control may be easily improved by providing the patient with psychological support capable of optimising his general level of adaptation, and that this can lead to excellent results with regard to specific problems which otherwise detract from the wellbeing of the patient and hamper the work of the medical team.

    Clinical practice sometimes brings to face with situations quite peculiar, potentially dangerous for the patient’s life. In the great majority of cases, pathologies associated with each other (cardiovascular, respiratory, neurological), while in other cases we can treat rare diseases or syndromes. It’s considered exceptional the simultaneous presence of “rare” pathologies in a single patient. This exceptionality has been a push to treat a patient as a “unique” asking for help to deeper studies of pharmacogenetics. Our case reports the management of a patient with Ehlers-Danlos syndrome (EDS) and Multiple Chemical Sensitivity (MCS), undergoing a total thyroidectomy. We found several problems, and we tried to find effective solutions for the management of the patient during the whole peri-operative process, from a clinical, pharmacological and also from a surgical point of view.

    The purpose of this study was to examine the effect of educational interventions on breast cancer patients during chemotherapy, with a secondary aim of focusing on describing symptoms in patients during chemotherapy and their effects on the quality of life of patients with breast cancer undergoing chemotherapy. The study was quasi-experimental. A sample of 120 patients participated, of which 60 were in the experimental group and 60 were in the control group. Pre/posttest quality-of-life subgroups were compared in terms of their mean scores. In the posttest in the experimental group, mean scores of the Family subscale, Health and Functioning subscale, Psychological/Spiritual subscale, and Social and Economic subscale correlated negatively and the difference was statistically significant (P < .05).

    Respiratory muscle dysfunction, particularly of the diaphragm, may play a key role in the pathophysiological mechanisms that lead to difficulty in weaning patients from mechanical ventilation. The limited mobility of critically ill patients, and of the diaphragm in particular when prolonged mechanical ventilation support is required, promotes the early onset of respiratory muscle dysfunction, but this can also be caused or exacerbated by other factors that are common in these patients, such as sepsis, malnutrition, advanced age, duration and type of ventilation, and use of certain medications, such as steroids and neuromuscular blocking agents. In this review we will study in depth this multicausal origin, in which a common mechanism is altered protein metabolism, according to the findings reported in various models. The understanding of this multicausality produced by the same pathophysiological mechanism could facilitate the management and monitoring of patients undergoing mechanical ventilation.

    Autosomal Dominant Polycystic Kidney Disease (ADPKD) is one of the most common monogenic disorders and the leading inheritable cause of end-stage renal disease worldwide. Cystic and noncystic extrarenal manifestations are correlated with variable clinical presentations so that an inherited disorder is now considered a systemic disease. Kidney and liver cystic infections are the most common infectious complications in ADPKD patients. Furthermore, it is well known that ADPKD is commonly associated with colonic diverticular disease which recently has been reported to be linked to increased risk of infection on hemodialysis patients. Herein, we present a case of anterior abdominal wall abscess caused by Enterococcus faecalis in a patient with ADPKD undergoing hemodialysis. Although the precise pathway of infection remains uncertain, the previous medical history as well as the clinical course of our patient led us to hypothesize an alternative route of infection from the gastrointestinal tract through an aberrant intestinal barrier into the bloodstream and eventually to an atypical location.

    Objectives To evaluate the impact of left ventricular (LV) chamber size on procedural and hospital outcomes of patients undergoing aortic valvuloplasty. Background Balloon aortic valvuloplasty (BAV) is used as an integral step during transcatheter aortic valve implantation. Patients with small, thickened ventricles are thought to have more complications during and following BAV. Methods Retrospective study of consecutive patients with severe, symptomatic calcific aortic stenosis who underwent retrograde BAV at Massachusetts General Hospital. We compared patients with left ventricular end-diastolic diameters (LVEDD) <4.0 cm (n = 31) to those with LVEDD ≥4.0 cm (n = 78). Baseline and procedural characteristics as well as clinical outcomes were compared. Multivariate logistic regression was used for the adjusted analysis. Results Patients with smaller LV chamber size were mostly women (80.7% vs. 19.4%, P < 0.01) and had a smaller body surface area (BSA), (1.61 ± 0.20 m2 vs. 1.79 ± 0.25 m2, P < 0.01). Patients with smaller LV chamber size had higher ejection fractions and thicker ventricles. Otherwise, baseline characteristics were similar. The intraprocedural composite of death, cardiopulmonary arrest, intubation, hemodynamic collapse, and tamponade was higher for patients with LVEDD < 4.0 cm (32.3% v. 11.5%, P = 0.01). Adjusting for age, gender, BSA, LV pressure, and New York Heart Association class, LVEDD < 4.0 cm remained an independent predictor of procedural (OR 5.1, 95% CI 1.4– 18.2) and in-hospital complications (OR 3.8, 95% CI 1.2–11.6). Conclusions Compared to patients undergoing BAV with LVEDD ≥4.0 cm, those with smaller LV chambers had worse procedural and in-hospital outcomes. PMID:22926957

    AIM: To determine the impact of red blood cell distribution width on outcome in anemic patients undergoing transcatheter aortic valve implantation (TAVI). METHODS: In a retrospective single center cohort study we determined the impact of baseline red cell distribution width (RDW) and anemia on outcome in 376 patients with aortic stenosis undergoing TAVI. All patients were discussed in the institutional heart team and declined for surgical aortic valve replacement due to high operative risk. Collected data included patient characteristics, imaging findings, periprocedural in hospital data, laboratory results and follow up data. Blood samples for hematology and biochemistry analysis were taken from every patient before and at fixed intervals up to 72 h after TAVI including blood count and creatinine. Descriptive statistics were used for patient’s characteristics. Kaplan-Meier survival curves were used for time to event outcomes. A recursive partitioning regression and classification was used to investigate the association between potential risk factors and outcome variables. RESULTS: Mean age in our study population was 81 ± 6.1 years. Anemia was prevalent in 63.6% (n = 239) of our patients. Age and creatinine were identified as risk factors for anemia. In our study population, anemia per se did influence 30-d mortality but did not predict longterm mortality. In contrast, a RDW > 14% showed to be highly predictable for a reduced short- and longterm survival in patients with aortic valve disease after TAVI procedure. CONCLUSION: Age and kidney function determine the degree of anemia. The anisocytosis of red blood cells in anemic patients supplements prognostic information in addition to that derived from the WHO-based definition of anemia. PMID:26981217

    Purpose: To determine the prevalence of psychosocial distress among patients undergoing radiotherapy (RT) for head and neck cancer and to examine the association between depression and anxiety and demographic and medical variables. Methods and Materials: A total of 40 patients (25 men and 15 women) with nonmetastatic head and neck cancer were enrolled in this prospective study and underwent RT administered with definitive (24 patients) or postoperative (16 patients) intent. Twenty patients (50%) received concurrent chemotherapy. All patients completed the Hospital Anxiety and Depression Scale and Beck Depression Inventory-II instrument before RT, on the last day of RT, and at the first follow-up visit. The effect of patient-, tumor-, and treatment-related factors on psychosocial distress was analyzed. Results: The prevalence of mild to severe pre-RT depression was 58% and 45% using the Hospital Anxiety and Depression Scale-D and Beck Depression Inventory-II scale, respectively. The prevalence of severe pre-RT anxiety was 7%. The depression levels, as determined by the Hospital Anxiety and Depression Scale and Beck Depression Inventory-II instrument increased significantly during RT and remained elevated at the first follow-up visit (p < 0.001 for both). The variables that were significantly associated with post-RT depression included a greater pre-RT depression level, employment status (working at enrollment), younger age (<55 years), single marital status, and living alone (p < 0.05, for all). Conclusion: The results of our study have shown that an alarming number of patients undergoing RT for head and neck cancer have symptoms suggestive of psychosocial distress even before beginning treatment. This proportion increases significantly during RT. Studies investigating the role of antidepressants and/or psychiatric counseling might be warranted in the future.

    Objective Knowledge about determinants of participation in lifestyle interventions in cancer patients undergoing chemotherapy, particularly with palliative intent, remains poor. The objective of the present study was to identify determinants of participating in a 12 month individualized, comprehensive lifestyle intervention, focusing on diet, physical activity, mental stress and smoking cessation, in cancer patients receiving chemotherapy with curative or palliative intent. The secondary objective was to identify participation determinants 4 months into the study. Methods Newly diagnosed cancer patients starting chemotherapy at the cancer center in Kristiansand/Norway (during a 16 month inclusion period) were screened. Demographic and medical data (age, sex, body mass index, education level, marital status, smoking status, Eastern Cooperative Oncology Group performance status (ECOG), diagnosis, tumor stage and treatment intention) was analyzed for screened patients. Results 100 of 161 invited patients participated. There were more females (69 vs. 48%; P = 0.004), breast cancer patients (46 vs. 25%; P = 0.007), non-smokers (87 vs. 74%; P = 0.041), younger (mean age 60 vs. 67 yrs; P < 0.001) and fitter (82 vs. 64% with EGOC 0; P = 0.036) participants vs. non-participants included. In multivariate logistic regression analyses, age (Odds Ratio 0.94, 95% Confidence Interval 0.91, 0.97) and smoking (0.42, 0.18, 0.99) were negatively associated with participation. After 4 months, 63 participants were still participating. Cancer type, smoking and age increased the probability of dropping out. Multivariate logistic regression revealed that age was the only significant determinant of 4 month participation (0.95, 0.91, 0.99). Patients aged >70 years were less likely to participate at baseline and 4 months. Conclusion Individualized lifestyle interventions in cancer patients undergoing chemotherapy appear to facilitate a high participation rate that declines with increasing

    BACKGROUND/AIM—Hypoxia and carbon dioxide rebreathing are potential problems during eye surgery in spontaneously breathing patients. The aim of the present study was to determine effectiveness of nasal application of oxygen to prevent hypoxia and carbon dioxide accumulation in spontaneously breathing patients undergoing cataract surgery.
METHODS—Oxygenation and carbon dioxide rebreathing were examined in 40 elderly patients using two different methods of oxygen supply—nasal v ambient air—with a constant flow of 2 l/min. Partial pressure of carbon dioxide under ophthalmic drapes, transcutaneous pressure of carbon dioxide, and the respiratory rate were measured during 25 minutes while oxygen was supplied via a nasal cannula or into the ambient air under the drapes.
RESULTS—In both groups carbon dioxide accumulation under the drapes, carbon dioxide rebreathing, tachypnoea, and an increase in peripheral oxygen saturation occurred. No significant differences were found between the two methods.
CONCLUSION—Nasal application of oxygen prevented hypoxia but did not prevent carbon dioxide accumulation in patients undergoing eye surgery under retrobulbar anaesthesia. Additionally, as a side effect when using nasal probes, irritation of the nose was described in half of the patients investigated.

    Abstract This cross-sectional study was designed to obtain the current prevalence of deep vein thrombosis (DVT) and analyze related risk factors in patients undergoing lumbar interbody fusion. Medical record data were collected from Department of Spinal Surgery, The Third Hospital of Hebei Medical University, between July 2014 and March 2015. Both univariate analysis and binary logistic regression analysis were performed to determine risk factors for DVT. A total of 995 patients were admitted into this study, including 484 men and 511 women, aged from 14 to 89 years old (median 50, IQR 19). The detection rate of lower limb DVT by ultrasonography was 22.4% (223/995) in patients undergoing lumbar interbody fusion. Notably, average VAS (visual analog scale) score in the first 3 days after surgery in the DVT group was more than that in the non-DVT group (Z = −21.69, P < 0.001). The logistic regression model was established as logit P = −13.257 + 0.056∗X1 − 0.243∗X8 + 2.085∗X10 + 0.001∗X12, (X1 = age; X8 = HDL; X10 = VAS; X12 = blood transfusion; x2 = 677.763, P < 0.001). In conclusion, advanced age, high postoperative VAS scores, and blood transfusion were risk factors for postoperative lower limb DVT. As well, the logistic regression model may contribute to an early evaluation postoperatively to ascertain the risk of lower limb DVT in patients undergoing lumbar interbody fusion surgery.

    Purpose. To compare the efficacy of perioperative ranibizumab injections on diabetic macular edema (DME) in patients undergoing cataract surgery. Methods. This study included 59 eyes of 59 patients. All patients had advanced cataract with DME and underwent an uneventful phacoemulsification surgery. There were 3 subgroups. The first group received intravitreal ranibizumab injection 2 weeks preoperatively, the second group received intraoperatively, and the third group received 2 weeks postoperatively. Follow-up examinations were performed at 1 week as well as at 1 and 3 months. Results. Baseline visual acuity showed a significant increase in all groups at 1 month. In group 1, compared to baseline value, foveal thickness (FT) increased significantly at 1 month and showed a significant decrease up to month 3. In group 2, FT increased at month 1 and this continued up to month 3. In group 3, FT increased at month 1 and was almost stable up to month 3. There were not any significant differences for visual acuity and FT between the groups. Conclusions. Although intrapostoperative ranibizumab injection for DME seems to be more effective than preoperative injections in patients undergoing cataract surgery, the treatment still needs to be continued following surgery.

    Recent studies have indicated that the ratio of C-reactive protein to albumin (CRP–Alb ratio) is associated with clinical outcomes in patients with disease. We examined the predictive value of this ratio in patients undergoing hemodialysis (HD). In this cross-sectional study, 91 eligible adult HD patients were analyzed, and the correlation between the CRP–Alb ratio and skeletal muscle mass normalized for body weight (SMM/wt; estimated using a bioelectrical impedance analyzer) was investigated. The mean age of the study participants was 54.9 ± 6.6 years (ranging from 27 to 64 years); 43 (47.2%) were men. The mean values for the SMM/wt were 39.1% ± 5.4%. The CRP–Alb ratio was found to be negatively correlated with SMM/wt (r = −0.33, P = 0.002) and creatinine (r = −0.20, P = 0.056). All the univariate significant and nonsignificant relevant covariates were selected for multivariable stepwise regression analysis. We determined that the homeostasis model assessment-estimated insulin resistance and CRP–Alb ratio were independent risk determinants for SMM/wt (βHOMA-IR = −0.18 and βCRP–Alb ratio = −3.84, adjusted R2 = 0.32). This study indicated that the CRP–Alb ratio may help clinicians in predicting muscle mass in adult patients undergoing HD. PMID:27768746

    Infiltrating macrophages play an important role in the production of inflammatory mediators by the adipose tissue of obese subjects. To reach the adipose tissue, peripheral monocytes are recruited by locally produced chemoattractants. However, little is known about the activation of monocytes in the peripheral blood of obese subjects. The objective of this study was to determine reactive oxygen species and endoplasmic reticulum stress as early markers of monocytic commitment with an inflammatory phenotype in the peripheral blood of nondiabetic obese patients. Patients were recruited from an academic general hospital; controls were voluntary students. Seven lean controls and 6 nondiabetic obese patients were included in the study. Monocytes were prepared from peripheral blood. Immunoblot, flow cytometry, and polymerase chain reaction were used to determine reactive oxygen species and endoplasmic reticulum stress. Increased reactive oxygen species and activation of endoplasmic reticulum stress were detected in the monocytes from obese patients. Reducing endoplasmic reticulum stress with a chemical chaperone reversed monocytic activation, as determined by the reduction of reactive oxygen species production. Thus, monocytes from nondiabetic obese patients are already committed with an inflammatory phenotype in peripheral blood; and reducing endoplasmic reticulum stress negatively modulates their activation.

    Background Conventional surgical risk scores lack accuracy in risk stratification of patients undergoing transcatheter aortic valve replacement (TAVR). Elevated levels of midregional proadrenomedullin (MR-proADM) levels are associated with adverse outcome not only in patients with manifest chronic disease states, but also in the general population. Objectives We investigated the predictive value of MR-proADM for mortality in an unselected contemporary TAVR population. Methods We prospectively included 153 patients suffering from severe aortic stenosis who underwent TAVR from September 2013 to August 2014. This population was compared to an external validation cohort of 205 patients with severe aortic stenosis undergoing TAVR. The primary endpoint was all cause mortality. Results During a median follow-up of 258 days, 17 out of 153 patients who underwent TAVR died (11%). Patients with MR-proADM levels above the 75th percentile (≥ 1.3 nmol/l) had higher mortality (31% vs. 4%, HR 8.9, 95% CI 3.0–26.0, P < 0.01), whereas patients with EuroSCORE II scores above the 75th percentile (> 6.8) only showed a trend towards higher mortality (18% vs. 9%, HR 2.1, 95% CI 0.8–5.6, P = 0.13). The Harrell’s C-statistic was 0.58 (95% CI 0.45–0.82) for the EuroSCORE II, and consideration of baseline MR-proADM levels significantly improved discrimination (AUC = 0.84, 95% CI 0.71–0.92, P = 0.01). In bivariate analysis adjusted for EuroSCORE II, MR-proADM levels ≥1.3 nmol/l persisted as an independent predictor of mortality (HR 9.9, 95% CI (3.1–31.3), P <0.01) and improved the model’s net reclassification index (0.89, 95% CI (0.28–1.59). These results were confirmed in the independent validation cohort. Conclusions Our study identified MR-proADM as a novel predictor of mortality in patients undergoing TAVR. In the future, MR-proADM should be added to the commonly used EuroSCORE II for better risk stratification of patients suffering from severe aortic stenosis. PMID

    Background Uterine atony (UA) is recognized as a leading cause of postpartum haemorrhage. However, knowledge of risk factors of haemorrhage-related morbidity among patients diagnosed with UA is uncertain. We investigated risk factors for haemorrhage-related morbidity among patients undergoing Caesarean delivery with UA. Methods We conducted a secondary analysis of data sourced from a 4-yr observational study at 19 US academic centres. Patients with UA were identified based on receiving methylergonovine or carboprost. Our primary outcome (haemorrhage-related morbidity) included a composite of intra- or postpartum transfusion; Caesarean hysterectomy; uterine or hypogastric artery ligation; intensive care admission for: pulmonary oedema, coagulopathy, adult respiratory distress syndrome, postoperative ventilation, or invasive line monitoring. Results Among 57 182 patients who underwent Caesarean delivery, 2294 (4%) patients developed UA. Haemorrhage-related morbidity occurred in 450 (19.6%) patients with UA. The risk of haemorrhage-related morbidity was increased among African-Americans [adjusted odds ratio (aOR)=2.36; 95% confidence interval (CI)=1.73–3.23], Hispanics (aOR=1.4; 95% CI=1.04–1.9), women with multiple gestations (aOR=1.59; 95% CI=1.06–2.38), placenta praevia (aOR=4.89; 95% CI=3.04–7.87), patients with ASA class III (aOR=1.4; 95 CI=1.03–1.9), or ASA class IV (aOR=5.88; 95% CI=2.48–13.9), exposure to general anaesthesia (GA) (aOR=2.4; 95% CI=1.59–3.62) and combined general and regional anaesthesia (aOR=4.0; 95% CI=2.62–6.09), and ≥2 prior Caesarean deliveries (aOR=1.62; 95% CI=1.1–2.39). Conclusions Among patients with UA undergoing Caesarean delivery, the risk of haemorrhage-related morbidity is increased in African-Americans, Hispanics, patients with multiple gestations, placenta praevia, ASA class III or IV, ≥2 prior Caesarean deliveries and those undergoing GA.

    Patients undergoing thyroid surgery with retrosternal goitre may raise concerns for the anaesthetist, especially airway management. We reviewed a multicentre prospective thyroid surgery database and extracted data for those patients with retrosternal goitre. Additionally, we reviewed the anaesthetic charts of patients with retrosternal goitre at our institution to identify the anaesthetic induction technique and airway management. Of 4572 patients in the database, 919 (20%) had a retrosternal goitre. Two cases of early postoperative tracheomalacia were reported, one in the retrosternal group. Despite some very large goitres, no patient required tracheostomy or cardiopulmonary bypass and there were no perioperative deaths. In the subset of 133 patients managed at our institution over six years, there were no major adverse anaesthetic outcomes and no patient had a failed airway or tracheomalacia. In the latter cohort, of 32 (24%) patients identified as having a potentially difficult airway, 17 underwent awake fibreoptic tracheal intubation, but two of these were abandoned and converted to intravenous induction and general anaesthesia. Eleven had inhalational induction; two of these were also abandoned and converted to intravenous induction and general anaesthesia. Of those suspected as having a difficult airway, 28 (87.5%) subsequently had direct laryngoscopy where the laryngeal inlet was clearly visible. We found no good evidence that thyroid surgery patients with retrosternal goitre, with or without symptoms and signs of tracheal compression, present the experienced anaesthetist with an airway that cannot be managed using conventional techniques. This does not preclude the need for multidisciplinary discussion and planning. PMID:25342401

    Abstract Objective To determine the Helicobacter pylori status of patients who underwent gastroscopy. Design Retrospective chart review. Setting Peace River Community Health Centre in rural northwestern Alberta. Participants Data were collected from patients who had a gastroscopy performed by either of 2 family physicians between January 1, 2011, and December 31, 2012. Main outcome measures The proportion of patients who had positive test results for H pylori overall and among first-time gastroscopy patients. For first-time gastroscopy patients, the associations between H pylori infection and patient age, sex, residence, and procedural indications and findings were explored. Results A total of 251 gastroscopies were conducted in 229 unique patients during the study period. Overall, 12.4% (95% CI 8.3% to 16.4%) of patients had positive results for H pylori and among the 159 first-time gastroscopy patients, 17.6% (95% CI 11.7% to 23.5%) had positive test results for H pylori. Helicobacter pylori status did not differ significantly by geography, sex, or age. The prevalence of H pylori was higher among patients with H pylori–related indications for gastroscopy (such as dyspepsia and upper gastrointestinal tract bleeding) than among patients with other indications; however, H pylori infection was not statistically significantly greater in patients diagnosed with peptic ulcer disease. Conclusion The prevalence of H pylori infection among patients undergoing gastroscopy in rural northern Alberta appears lower than other Canadian estimates. In regions with low H pylori rates, patients with dyspepsia might be better served by acid suppression and nonsteroidal anti-inflammatory drug cessation before investigating for H pylori infection. Population-based research is required to further describe regional differences in H pylori rates. PMID:27629690

    Peripheral chemoreceptor activity/sensitivity is enhanced in chronic heart failure (HF), and sensitivity is linked to greater mortality. This study aimed to determine the role of the peripheral chemoreceptor in cardiovascular control at rest and during exercise in HF patients and controls. Clinically stable HF patients (n = 11; ejection fraction: 39 ± 5%) and risk-matched controls (n = 10; ejection fraction: 65 ± 2%) performed randomized trials with or without dopamine infusion (2 μg·min(-1)·kg(-1)) at rest and during 40% maximal voluntary contraction handgrip (HG) exercise, and a resting trial of 2 min of inspired 100% oxygen. Both dopamine and hyperoxia were used to inhibit the peripheral chemoreceptor. At rest in HF patients, dopamine decreased ventilation (P = 0.02), decreased total peripheral resistance index (P = 0.003), and increased cardiac and stroke indexes (P ≤ 0.01), yet there was no effect of dopamine on these variables in controls (P ≥ 0.7). Hyperoxia lowered ventilation in HF (P = 0.01), but not in controls (P = 0.9), indicating suppression of the peripheral chemoreceptors in HF. However, no decrease of total peripheral resistance index was observed in HF. As expected, HG increased heart rate, ventilation, and brachial conductance of the nonexercising arm in controls and HF patients. During dopamine infusion, there were no changes in mean arterial pressure, heart rate, or ventilation responses to HG in either group (P ≥ 0.26); however, brachial conductance increased with dopamine in the control group (P = 0.004), but decreased in HF (P = 0.02). Our findings indicate that the peripheral chemoreceptor contributes to cardiovascular control at rest in HF patients and during exercise in risk-matched controls.

    Objective Protective ventilation (PV) has been validated in patients with acute respiratory distress syndrome. However, the effect of PV in patients undergoing major surgery is controversial. The study aimed to explore the beneficial effect of PV on patients undergoing a major operation by systematic review and meta-analysis. Setting Various levels of medical centres. Participants Patients undergoing general anaesthesia. Interventions PV with low tidal volume. Primary and secondary outcome measures Study end points included acute lung injury (ALI), pneumonia, atelectasis, mortality, length of stay (LOS) in intensive care unit (ICU) and hospital. Methods Databases including PubMed, Scopus, EBSCO and EMBASE were searched from inception to May 2015. Search strategies consisted of terms related to PV and anaesthesia. We reported OR for binary outcomes including ALI, mortality, pneumonia, atelectasis and other adverse outcomes. Weighted mean difference was reported for continuous outcomes such as LOS in the ICU and hospital, pH value, partial pressure of carbon dioxide, oxygenation and duration of mechanical ventilation (MV). Main results A total of 22 citations were included in the systematic review and meta-analysis. PV had protective effect against the development of ALI as compared with the control group, with an OR of 0.41 (95% CI 0.19 to 0.87). PV tended to be beneficial with regard to the development of pneumonia (OR 0.46, 95% CI 0.16 to 1.28) and atelectasis (OR 0.68, 95% CI 0.46 to 1.01), but statistical significance was not reached. Other adverse outcomes such as new onset arrhythmia were significantly reduced with the use of PV (OR 0.47, 95% CI 0.48 to 0.93). Conclusions The study demonstrates that PV can reduce the risk of ALI in patients undergoing major surgery. However, there is insufficient evidence that such a beneficial effect can be translated to more clinically relevant outcomes such as mortality or duration of MV. Trial registration number The study

    Abstract Objective: To evaluate the changes in lung function in the first year after single lung transplantation in patients with idiopathic pulmonary fibrosis (IPF). Methods: We retrospectively evaluated patients with IPF who underwent single lung transplantation between January of 2006 and December of 2012, reviewing the changes in the lung function occurring during the first year after the procedure. Results: Of the 218 patients undergoing lung transplantation during the study period, 79 (36.2%) had IPF. Of those 79 patients, 24 (30%) died, and 11 (14%) did not undergo spirometry at the end of the first year. Of the 44 patients included in the study, 29 (66%) were men. The mean age of the patients was 57 years. Before transplantation, mean FVC, FEV1, and FEV1/FVC ratio were 1.78 L (50% of predicted), 1.48 L (52% of predicted), and 83%, respectively. In the first month after transplantation, there was a mean increase of 12% in FVC (400 mL) and FEV1 (350 mL). In the third month after transplantation, there were additional increases, of 5% (170 mL) in FVC and 1% (50 mL) in FEV1. At the end of the first year, the functional improvement persisted, with a mean gain of 19% (620 mL) in FVC and 16% (430 mL) in FEV1. Conclusions: Single lung transplantation in IPF patients who survive for at least one year provides significant and progressive benefits in lung function during the first year. This procedure is an important therapeutic alternative in the management of IPF. PMID:26398749

    2012-01-01

    Background Over the past decade, advances in cancer treatments have been counterbalanced by a rising number of immunosuppressed patients with a multitude of new risk factors for infection. Hence, the aim of this study was to determine risk factors, infectious pathogens in blood and oral cavity of oral cancer patients undergoing different treatment procedures. Methods The present prospective cohort analysis was conducted on the patients undergoing treatment in the radiotherapy unit of Regional Cancer Institute, Pt. B.D. Sharma University of Health Sciences, Rohtak, Haryana, during the period of January 2007 to October 2009. Total 186 patients with squamous cell carcinoma of oral cavity were analyzed in the study. Based on treatment procedures patients were divided into three groups, group I were under radiotherapy, group II under chemotherapy and group III were of radio chemotherapy together. Clinical isolates from blood and oral cavity were identified by following general microbiological, staining and biochemical methods. The absolute neutrophile counts were done by following the standard methods. Results Prevalent bacterial pathogens isolated were Staphylococcus aureus, Escherichia coli, Staphylococcus epidermidis, Pseudomonas aeruginosa, Klebsiella pneumonia, Proteus mirabilis, Proteus vulgaris and the fungal pathogens were Candida albicans, Aspergillus fumigatus. The predominant gram negative bacteria, Pseudomonas aeruginosa and Klebsiella pneumonia were isolated from blood of radiotherapy and oral cavity of chemotherapy treated cases respectively. The predominance of gram positive bacteria (Staphylococcus aureus and Staphylococcus epidermidis) were observed in blood of chemotherapy, radio chemotherapy cases and oral cavity of radiotherapy, radio chemotherapy treated cases. Our study also revealed the presence of C. albicans fungi as most significant oral cavity pathogens in radiotherapy and radio chemotherapy cases. Conclusion Gram positive bacteria and Gram

    Background and Objectives The growing implantations of electrophysiological devices in the context of increasing rates of chronic antithrombotic therapy in cardiovascular disease patients underscore the importance of an effective periprocedural prophylactic strategy for prevention of bleeding complications. We assessed the risk of significant bleeding complications in patients receiving anti-platelet agents or anticoagulants at the time of permanent pacemaker (PPM) implantation. Subjects and Methods We reviewed bleeding complications in patients undergoing PPM implantation. The use of aspirin or clopidogrel was defined as having taking drugs within 5 days of the procedure and warfarin was changed to heparin before the procedure. A significant bleeding complication was defined as a bleeding incident requiring pocket exploration or blood transfusion. Results Permanent pacemaker implantations were performed in 164 men and 96 women. The mean patient age was 73±11 years old. Among the 260 patients, 14 patients took warfarin (in all of them, warfarin was changed to heparin at least 3 days before procedure), 54 patients took aspirin, 4 patients took clopidogrel, and 25 patients took both. Significant bleeding complications occurred in 8 patients (3.1%), all of them were patients with heparin bridging (p<0.0001). Heparin bridging markedly increased the length of required hospital stay when compare with other groups and the 4 patients (1.5%) that underwent the pocket revision for treatment of hematoma. Conclusion This study suggests that hematoma formation after PPM implantation was rare, even among those who had taken the anti-platelet agents. The significant bleeding complications frequently occurred in patients with heparin bridging therapy. Therefore, heparin bridging therapy was deemed as high risk for significant bleeding complication in PPM implantation. PMID:22977449

    Recent evidence has suggested that a moist environment plays an important role in wound healing. Karayahesive, one type of hydrocolloidal dressing, contains natural karaya gum as a hydrophilic gel. We applied hydrocolloidal dressing to operative wounds in 147 patients who underwent cardiovascular surgery from April 2001 through August 2002 to evaluate its clinical usefulness. The dressing was kept on the wounds for 7 days after operation, but was immediately switched to conventional dressing with gauze if there was any problem. A total of 144 patients (98%) had no wound chest infections. Good wound healing was obtained with only 1 dressing, removed 7 days after operation, in 128 patients (87%). In 19 patients (13%), the hydrocolloidal dressing was switched to conventional dressing. In 13 of these patients the hydrocolloidal dressing dissolved naturally or exudation occurred; clinically, there were no local problems; however, 3 patients had infection, 2 had fat necrosis, and 1 had burn injury caused by electrocautery. No patients had skin problems caused by this dressing. We conclude that hydrocolloidal dressing can be used safely and effectively in patients undergoing cardiovascular surgery and reduce the workload of healthcare workers.

    According to the Hunter Serotonin Toxicity Criteria, the presence of either clonus or hyperreflexia is a must for making a diagnosis of serotonin syndrome (SS). We report five patients with SS who had areflexia because of associated polyneuropathy. None of the patients fulfilled the Hunter criteria for SS. However, all five patients had features suggestive of neuromuscular hyperactivity, autonomic hyperactivity and altered mental status and fulfilled the Sternbach criteria for SS. All patients responded to cyproheptadine within 5 days to 2 weeks duration. These cases highlight the limitations of the Hunter criteria for SS in patients with associated polyneuropathy.

    Patients diagnosed with an Abdominal Aorta Aneurism who undergo an operation using either conventional surgery or endovascular surgery require a series of different nursing treatment. The authors comparatively analyze nursing treatment applied to patients who have undergone an abdominal aorta aneurism according to the technique used; their study is retrospective, observational and comparative for all 61 patients who underwent an abdominal aorta aneurism in the Navarre Hospital in 2004. The authors describe both techniques, their advantages and inconveniences, and in a well-developed comparative manner, point out the differences in nursing treatment during post-operative care. Part of this study was presented in a poster format at the XVII National Congress on Vascular Nursing. PMID:16875361

    We describe a case of peritonitis with isolation of a group JK corynebacterium from the peritoneal effluent in a patient undergoing continuous ambulatory peritoneal dialysis and treated with corticosteroids. Therapy with intraperitoneal vancomycin resulted in a rapid eradication of the organism. However, only 1 month after discontinuation of the 26-day therapy, a second episode of peritonitis with JK corynebacterium occurred. After vancomycin was restarted, the organism disappeared again from the peritoneal fluid, but the patient died a few days later from heart failure apparently unrelated to the infection. Some authors have mentioned the isolation of diphtheroids (without further identification) from peritoneal effluent of continuous ambulatory peritoneal dialysis patients, but to our knowledge, this is the first report of peritonitis associated with JK corynebacterium, an opportunistic organism that must be differentiated from other corynebacteria.

    Objective The objective of the present study is to determine the incidence of delirium and the associated factors in patients undergoing open heart surgery. Method This is an Analytic-descriptive study conducted on 404 patients undergoing elective open heart surgery in Fatemeh Zahra Heart Center, Sari, over the period of 6 months from July to December 2011. Sampling was achieved in a nonrandomized targeted manner and delirium was assessed using NeeCham questionnaire. A trained nurse evaluated the patients for delirium and completed the risk factor checklist on days 1 to 5 after surgery. Data analyses were accomplished using survival analysis (Kaplan-Meier and Cox regression) on SPSS software version 15. Results We found that variables, including ventilation time, increased drainage during the first 24 hours, the need for re-operation in the first 24 hours, dysrhythmias, use of inotropic agents, increased use of analgesics, increased arterial carbon dioxide, lack of visitors, and use of physical restrainers were associated with the development of delirium. In addition, we found a delirium incidence of 29%. Conclusion Diagnosis of cognitive disorders is of utmost value; therefore, further studies are required to clarify the risk factors because controlling them will help prevent delirium. PMID:25337310

    This study was performed to evaluate the effects of cryoanalgesia combined with thoracic epidural analgesia on pain and respiratory complications in patients undergoing thoracotomy. Ninety patients were prospectively randomised to epidural analgesia alone (n = 45) or epidural analgesia and cryoanalgesia combined (n = 45). We monitored the use of rescue pain medication and changes in forced vital capacity and forced expired volume in 1 s, and recorded pain and opioid-related side-effects during the immediate postoperative period. The incidence of post-thoracotomy pain and numbness were also assessed up to the sixth month after surgery. Cryoanalgesia combined with thoracic epidural analgesia was associated with earlier recovery in pulmonary function, less pain during movement and a lower daily requirement for rescue analgesia one week after surgery. However, the combination of cryoanalgesia and epidural analgesia failed to decrease the incidence of long-term pain and numbness. In view of its associated long-term morbidity, cryoanalgesia combined with thoracic epidural analgesia is not recommended for patients undergoing thoracotomy. PMID:15479314

    Patients with complex ventral/incisional hernias often undergo an abdominal wall reconstruction (AWR). These operations have a high cost of care and often result in a long hospital stay and high complication rates. Using the principles of clinical quality improvement (CQI), several attempts at process improvement were implemented in one hernia program over a 3-year period. For consecutive cases of patients undergoing abdominal wall reconstruction, process improvement attempts included the use of a long-term resorbable synthetic mesh (TIGR® Resorbable Matrix, Novus Scientific, Uppsala, Sweden) in place of a biologic mesh, the use of the transversus abdominis release approach in place of an open or endoscopic component separation (external oblique release) technique, and the use of a preoperative transversus abdominis plane (TAP) block using a long-acting local anesthetic (Exparel®, Pacira Pharmaceutical, Parsippany, NJ) as a part of perioperative multi-modal pain management and an enhanced recovery program. After over 60 cases, improvement in materials costs and postoperative outcomes were documented. No mesh-related complications occurred and no mesh removal was required. In this real-world, value-based application of CQI, several attempts at process improvement led to decreased costs and improved outcomes for patients who underwent abdominal wall reconstruction for complex ventral/incisional hernias. Value-based CQI could be a tool for improved health care value globally.

    Purpose. To assess visual function and its response to serial intravitreal ranibizumab (Lucentis, Genentech) in patients with neovascular age-related macular degeneration (nv-AMD). Methods. Forty-seven eyes of 47 patients with nv-AMD, and corrected distance visual acuity (CDVA) logMAR 0.7 or better, undergoing intravitreal injections of ranibizumab, were enrolled into this prospective study. Visual function was assessed using a range of psychophysical tests, while mean foveal thickness (MFT) was determined by optical coherence tomography (OCT). Results. Group mean (±sd) MFT reduced significantly from baseline (233 (±59)) to exit (205 (±40)) (P = 0.001). CDVA exhibited no change between baseline and exit visits (P = 0.48 and P = 0.31, resp.). Measures of visual function that did exhibit statistically significant improvements (P < 0.05 for all) included reading acuity, reading speed, mesopic and photopic contrast sensitivity (CS), mesopic and photopic glare disability (GD), and retinotopic ocular sensitivity (ROS) at all eccentricities. Conclusion. Eyes with nv-AMD undergoing intravitreal ranibizumab injections exhibit improvements in many parameters of visual function. Outcome measures other than CDVA, such as CS, GD, and ROS, should not only be considered in the design of studies investigating nv-AMD, but also in treatment and retreatment strategies for patients with the condition.

    Purpose: To assess the predictive significance of serum glutathione (GSH) and tumor tissue DNA damage in the treatment of cervical cancer patients undergoing chemoradiotherapy. Methods and Materials: This study included subjects undergoing hysterectomy (for normal cervix tissue) and cervical cancer patients who underwent conventional concurrent chemoradiotherapy (cisplatin once per week for 5 weeks with concurrent external radiotherapy of 2 Gy per fraction for 5 weeks, followed by two applications of intracavitary brachytherapy once per week after 2 weeks' rest). Blood was collected after two fractions, whereas both blood and tissues were collected after five fractions of radiotherapy in separate groups of subjects. Serum for total GSH content and tissues were processed for single-cell gel electrophoresis (SCGE) assay for DNA damage analysis. Clinical tumor radioresponse was assessed 2 months after the completion of treatment as complete responders (CR) (100% shrinkage), partial responders (PR) (>50%), and nonresponders (NR) (<50%). Results: Serum GSH content depleted significantly after a total dose of 4 Gy and 10 Gy of radiotherapy with a single dose of cisplatin, which was significantly lesser in NR than of CR patients. Similarly, Olive Tail Moment, the index of DNA damage, indicated significantly higher values in the fifth fraction of radiotherapy (5-RT) than in pretreatment. The DNA damage after 5-RT in the NR subgroup was significantly lower than that of CR. Conclusions: Serum GSH analysis and tumor tissue SCGE assay found to be useful parameters for predicting chemoradioresponse prior to and also at an early stage of treatment of cervical cancers.

    Previous studies suggest a correlation of central venous pressure (CVP) with peripheral venous pressure (PVP) in different clinical settings. The effect of body temperature on PVP and its agreement with CVP in patients under general anesthesia are investigated in this study. Fifteen American Society of Anesthesiologists I-II patients undergoing elective craniotomy were included in the study. CVP, PVP, and core (Tc) and peripheral (Tp) temperatures were monitored throughout the study. A total of 950 simultaneous measurements of CVP, PVP, Tc, and Tp from 15 subjects were recorded at 5-minute intervals. The measurements were divided into low- and high-Tc and -Tp groups by medians as cutoff points. Bland-Altman assessment for agreement was used for CVP and PVP in all groups. PVP measurements were within range of +/-2 mm Hg of CVP values in 94% of the measurements. Considering all measurements, mean bias was 0.064 mm Hg (95% confidence interval -0.018-0.146). Corrected bias for repeated measurements was 0.173 +/- 3.567 mm Hg (mean +/- SD(corrected)). All of the measurements were within mean +/- 2 SD of bias, which means that PVP and CVP are interchangeable in our setting. As all the measurements were within 1 SD of bias when Tc was > or = 35.8 degrees C, even a better agreement of PVP and CVP was evident. The effect of peripheral hypothermia was not as prominent as core hypothermia. PVP measurement may be a noninvasive alternative for estimating CVP. Body temperature affects the agreement of CVP and PVP, which deteriorates at lower temperatures.

    Background Pulmonary vein isolation (PVI) for atrial fibrillation (AF) is associated with a transient increased risk of thromboembolic and hemorrhagic events. We hypothesized that dabigatran can be safely used as an alternative to continuous warfarin for the peri-procedural anticoagulation in PVI. Methods and Results 999 consecutive patients undergoing PVI were included; 376 patients were on dabigatran (150 mg) and 623 were on warfarin with therapeutic INR. Dabigatran was held 1 to 2 doses prior to PVI and restarted at the conclusion of the procedure or as soon as patients were transferred to the nursing floor. Propensity score matching was applied to generate a cohort of 344 patients in each group with balanced baseline data. Total hemorrhagic and thromboembolic complications were similar in both groups, before (3.2% vs 3.9%; p = 0.59), and after (3.2% vs 4.1%; p = 0.53) matching. Major hemorrhage occurred in 1.1% vs 1.6% (p = 0.48) before, and 1.2% vs 1.5% (p = 0.74) after matching in the dabigatran vs warfarin group respectively. A single thromboembolic event occurred in each of the dabigatran and warfarin groups. Despite higher doses of intra-procedural heparin, the mean ACT was significantly lower in patients who held dabigatran for 1 or 2 doses than those on warfarin. Conclusions Our study found no evidence to suggest a higher risk of thromboembolic or hemorrhagic complications with use of dabigatran for peri-procedural anticoagulation in patients undergoing PVI compared to uninterrupted warfarin therapy.

    A recent histological study of resected scallop-P2 in mitral valve (MV) prolapse, showed that chordae tendinae may be missing or hidden in superimposed fibrous tissue of the leaflets, contributing to their thickening. This may have relevant clinical implication because detailed analysis of MV leaflets has a central role in the evaluation of patients undergoing repair. The aim of this study was to analyze MV leaflets focusing on thickness of prolapsing segments and the presence of chordal rupture (CR). We enrolled 246 patients (age 63 ± 13 years, 72 men) with isolated P2 prolapse and also 50 age-matched patients with normal MV anatomy as control group. Transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) were retrospectively analyzed to quantify the length and the proximal and distal thickness of both anterior (A2) and posterior (P2) MV scallops. Measurements were performed at end diastole in the standard TTE and TEE views. TTE and TEE measurements were feasible in all cases. Echocardiographically 176 patients had CR (group A), 45 had no rupture (group B), and 25 had an uncertain diagnosis (group C). All pathological groups showed thickening and elongation of involved leaflets versus normal, whereas no differences in leaflets characteristics were found among MV groups. Most patients undergoing MV repair had CR with thickening of the prolapsed segment. These findings are in agreement with recent histological studies showing superimposed fibrous tissue on MV leaflets partially including ruptured chordae. This may also explain that in cases without ruptured chordae, thickness of the leaflets is markedly increased (hidden chordae?). In conclusion, detailed analysis of MV apparatus may further improve knowledge of these patients and may influence surgical timing. PMID:27184171

    Vitamin D is recognized as an essential component in bone health, muscle function, and immune system regulation. This study sought to characterize the prevalence of hypovitaminosis D in patients undergoing total shoulder arthroplasty (TSA), reverse total shoulder arthroplasty (RSA), and shoulder hemiarthroplasty (HA). Between September 2013 and December 2014, a total of 218 patients undergoing TSA, RSA, and HA by a single surgeon were screened for hypovitaminosis D and retrospectively reviewed. Demographic variables and risk factors were recorded. Overall, 93 shoulder arthroplasty patients (43%) were vitamin D insufficient (<30 ng/mL) and 24 patients (11%) were vitamin D deficient (<20 ng/mL). Body mass index (BMI) had a significant effect on vitamin D levels; BMI of 30 kg/m(2) or greater was associated with lower vitamin D levels (31.5±12.1 ng/mL) compared with patients with a BMI of less than 30 kg/m(2) (36.2±15.7 ng/mL, P ≤.01). The absence of supplementation with vitamin D and calcium prior to serum testing was the most significant risk factor for hypovitaminosis D (odds ratio [OR], 8.234, P<.001). Age, gender, race, smoking status, American Society of Anesthesiologists (ASA) score, procedure, and surgical indication were not significant. This is the largest cohort of shoulder arthroplasty patients screened for hypovitaminosis D. Almost half (43%) of the study population was insufficient, and both the absence of supplementation prior to serum testing and BMI of 30 kg/m(2) or greater were found to be predictive of lower serum 25-hydroxyvitamin D levels. Given the extent of vitamin D involvement in normal musculoskeletal physiology, routine preoperative evaluation is merited. [Orthopedics. 2016; 39(4):e651-e656.]. PMID:27286046

    Appropriate management of patients with mechanical prosthetic valves on warfarin during dental procedures is crucial. If the patients continue warfarin, they might develop bleeding, while interruption of therapy can cause thromboembolic events. Bridging therapy (mostly heparin) is used in some patients, while others stop medications. There is no unifying protocol. Information on management of patients on warfarin undergoing dental procedures in Saudi Arabia is lacking. Therefore, the current study aimed to provide more insight into various approaches utilized by clinicians to deal with such patients at a large teaching hospital in Riyadh, and to evaluate the frequency and severity of bleeding and thromboembolic complications during different types of dental procedures in this population. This was a cohort study. Patient records were used to collect data on peri-procedural management of patients on warfarin, continuation or interruption of warfarin therapy, as well as bleeding and thromboembolic complications. Fifty medical records were reviewed from March to October 2012. Regarding management, 10% had no proper documentation, 74% underwent bridging therapy, 12% discontinued warfarin therapy, and 4% continued warfarin. Of the patients, 31% had minor bleeding (15% in patients on bridging therapy and 16% in patients continuing warfarin). Thromboembolic complications were documented in 4%, (2% in those on bridging therapy and 2% in those discontinuing warfarin). Patients on bridging therapy (heparin) were admitted to the hospital for a mean of five days, and none of the other patients were admitted. Adopting the protocol to continue warfarin caused bleeding tendency that was controlled with the usual measures, with more cost effectiveness, and no thromboembolic risks. PMID:27679745

    Since cancer vaccines do not always elicit beneficial effects in treated patients, identification of biomarkers for predicting clinical outcomes would be highly desirable. We previously reported that abnormal granulocytes present in peripheral blood mononuclear cells (PBMC) may contribute to poor prognosis in advanced prostate cancer patients receiving personalized peptide vaccination (PPV). In the current study, we examined whether soluble factors derived from granulocytes, such as matrix metalloproteinase 9 (MMP-9), myeloperoxidase (MPO), and arginase 1 (ARG1), and inhibitory cytokine TGFβ in pre-vaccination plasma were useful for predicting prognosis after PPV in advanced cancer patients. In biliary tract cancer (n=25), multivariate Cox regression analysis demonstrated that patients with higher plasma MMP-9 levels had a significantly worse overall survival (OS) [hazard ratio (HR) = 4.637, 95% confidence interval (CI) = 1.670 - 12.877, P = 0.003], whereas MPO, ARG1, or TGFβ levels were not correlated with OS. Similarly, patients with higher MMP-9 levels showed worse prognosis than those with lower MMP-9 levels in other types of advanced cancers, including non-small cell lung cancer (n=32, P = 0.037 by log-rank test), and pancreatic cancer (n=41, P = 0.042 by log-rank test). Taken together, plasma MMP-9 levels before vaccination might be potentially useful as a biomarker for selecting advanced cancer patients who would benefit from PPV. PMID:26325075

    Extracorporeal shockwave lithotripsy (SWL) currently is accepted as the preferred treatment for most renal and upper ureteral calculi. However, little is known about the infection risks of SWL. In this study, the incidence and severity of urinary tract infection in 117 patients with renal calculi undergoing SWL were evaluated and the stone characteristics of those with and without infection were compared. The patients were followed clinically and bacteriologically 1 and 14 days after the procedure. Bacteriuria was noted in six patients within 24 hours after SWL. No bacteriuria was noted 2 weeks later. Of these patients, three were symptomatic (including dysuria, burning, and fever >38 degrees C). No patient was hospitalized. We found no significant correlation between the occurrence of bacteriuria and the number or size of the stones (P > 0.05), nor was there any correlation between bacteriuria and the stone-free rate or the location of the calculi (P > 0.05). However, there was a significantly higher risk of urinary tract infection in patients with struvite stones than in those with other types of stones (17.3% v 2.1%). In patients with infection stones, prophylactic antimicrobial chemotherapy is necessary even if bacteriuria is not present before SWL.

    Nausea and vomiting are important complications after craniotomy, for which there are little published epidemiologic data. We retrospectively examined the incidence of postcraniotomy nausea and vomiting to define risk factors. Medical records from 199 adults undergoing elective craniotomy were identified. Data extracted from surgery and the initial 48 hours postoperatively included gender, age, supratentorial versus infratentorial craniotomy, type of anesthesia (general versus monitored anesthesia care), intraoperative fentanyl dose, duration of anesthesia, antiemetic administration intraoperatively and postoperatively, and incidence of postoperative nausea, emesis, and opioid use. Postoperative nausea was recorded in 99 patients (50%) and emesis in 78 patients (39%). Postoperative opioids were administered to 170 patients (85%). Antiemetics were given intraoperatively to 13 patients (7%) and postoperatively to 121 patients (61%). More women (61%) than men (37%) had nausea (P = 0.001); emesis (women = 46%; men = 31%, P = 0.03); and postoperative antiemetic use (women = 69%; men = 51%, P = 0.013). The incidence of postoperative nausea (P = 0.04) and vomiting (P = 0.06) was greater in patients having infratentorial surgery. Emesis was more frequent in younger patients (P = 0.03). Postoperative nausea and vomiting were independent of anesthetic duration, fentanyl dose, or postoperative opioid use and occurred with similar frequency after general anesthesia or monitored anesthesia care. We conclude that postoperative nausea and vomiting occur frequently after craniotomy. Infratentorial surgery, female gender, and younger age are significant risk factors for this complication.

    Background. The aim of this study is to evaluate the usefulness of serum N-glycan profiling for prognosis in hemodialysis patients. Methods. Serum N-glycan analysis was performed in 100 hemodialysis patients in June 2008 using the glycoblotting method, which allows high-throughput, comprehensive, and quantitative N-glycan analysis. All patients were longitudinally followed up for 5 years. To evaluate the independent predictors for prognosis, patients' background, blood biochemistry, and N-glycans intensity were analyzed using Cox regression multivariate analysis. Selected N-glycans and independent factors were evaluated using the log-rank test with the Kaplan-Meier method to identify the predictive indicators for prognosis. Each patient was categorized according to the number of risk factors to evaluate the predictive potential of the risk criteria for prognosis. Results. In total, 56 N-glycan types were identified in the hemodialysis patients. Cox regression multivariate analysis showed cardiovascular events, body mass index, maximum intima media thickness, and the serum N-glycan intensity of peak number 49 were predictive indicators for overall survival. Risk classification according to the number of independent risk factors revealed significantly poor survival by increasing the number of risk factors. Conclusions. Serum N-glycan profiling may have a potential to predict prognosis in patients undergoing hemodialysis. PMID:24453820

    Objective. To investigate the effects of diabetes mellitus (DM) in patients undergoing off-pump coronary artery bypass grafting (OPCAB). Method. A total of 728 patients with DM and 1380 patients without DM who underwent OPCAB treatment from March 2012 to April 2015 were reviewed. The effects of DM on intraoperative variables and postoperative complications were determined using propensity score analysis. Results. Two well-matched subgroups were selected using propensity score analysis (DM = 728, no-DM = 728) to compare the perioperative outcome. The duration of the ICU stay, in hours (55.2 ± 53.0 versus 49.29 ± 51.30, P < 0.05), postoperative new-onset atrial fibrillation (20.9% versus 14.97%, P < 0.05), and postoperative infection (9.2% versus 4.67%, P < 0.05) were greater in DM patients, as indicated by univariate analysis. Conclusion. OPCAB was found to be effective in DM patients, but postoperative infection and postoperative new-onset atrial fibrillation were found to be more likely to occur in DM patients than in other patients. DM was found to be a powerful risk factor for postoperative infection and postoperative new-onset atrial fibrillation. PMID:27777946

    The literature reports poor correlation between coagulation screening and prediction of bleeding risk in children. Our aim is to determine whether there is a role for coagulation studies in children undergoing percutaneous intervention for appendiceal abscesses. A retrospective review of 1805 patients presenting with a diagnosis of appendicitis from September 2008 to September 2013 was performed. Patients presenting with appendiceal abscess who underwent percutaneous intervention were selected for further review (n = 131). A total of 76 patients (58%) had normal coagulation studies, whereas 55 (42%) had elevated values. An international normalized ratio ≥ 1.3 was found in 26 patients. Patients with normal coagulation values had an incidence of bleeding of 1.3 per cent. In the abnormal coagulation group, 8 patients received fresh frozen plasma before intervention, whereas 47 did not. There was one hematoma noted in each group with an incidence of bleeding of 3.6 per cent. The overall incidence of hematoma was 2.3 per cent with no significant difference in bleeding risk between the normal and abnormal coagulation groups. In conclusion, although many patients are found to have elevated coagulation studies, most do not have bleeding complications after intervention. There is poor correlation between coagulation screening and postprocedural outcomes evidenced by the low risk of bleeding.

    BACKGROUND Management of patients requiring antiplatelet therapy with clopidogrel (Plavix) and major lung resection must balance the risks of bleeding and cardiovascular events. We reviewed our experience with patients treated with clopidogrel perioperatively to examine outcomes, including results of a new strategy for high-risk patients. METHODS Patients who underwent major lung resection and received perioperative clopidogrel between January 2005 and September 2010 were reviewed. Initially, clopidogrel management consisted of discontinuation approximately 5 days before surgery and resumption immediately after surgery. Following July 2010, high-risk patients (drug-eluting coronary stent placement within prior year or previous coronary event after clopidogrel discontinuation) were admitted 2–3 days preoperatively and bridged with the intravenous GP IIb/IIIa receptor inhibitor eptifibatide (Integrilin) according to a multidisciplinary cardiology/anesthesiology/thoracic surgery protocol. Outcomes were compared to control patients (matched for preoperative risk factors and extent of pulmonary resection) who did not receive perioperative clopidogrel. RESULTS Fifty-four patients who had major lung resection between January 2005 and September 2010 and received clopidogrel perioperatively were matched with 108 controls. Both groups had similar mortality, postoperative length of stay, and no differences in the rates of perioperative transfusions, reoperations for bleeding, myocardial infarctions, and strokes. Seven of the 54 clopidogrel patients were admitted preoperatively for an eptifibatide bridge. Two of these patients received perioperative transfusions, but there were no mortalities, reoperations, myocardial infarctions, or stroke. CONCLUSIONS Patients taking clopidogrel can safely undergo major lung resection. Treatment with an eptifibatide bridge may minimize the risk of cardiovascular events in higher risk patients.

    A best evidence topic in cardiovascular surgery was written according to a structured protocol. The question addressed was whether patients with severe asymptomatic carotid and coronary artery diseases should undergo simultaneous carotid endarterectomy (CEA) and coronary artery bypass grafting (CABG). A total of 624 papers were found using the reported search, of which 20 represent the best evidence to answer the clinical question. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results and study results of these papers are tabulated. Previous cohort studies showed mixed results, while advocating for the necessity of a randomized controlled trial (RCT). A recent RCT showed that patients undergoing prophylactic or simultaneous CEA + CABG had lower rates of stroke (0%) compared with delayed CEA 1–3 months after CABG (7.7%), without significant perioperative mortality difference. This study included patients with unilateral severe (>70%) asymptomatic carotid stenosis requiring CABG. An earlier partly randomized trial also showed better outcomes for patients undergoing simultaneous procedures (P = 0.045). Interestingly, systematic reviews previously failed to show compelling evidence supporting prophylactic CEA. This could be partly due to the fact that these reviews collectively analyse different cohort qualities. Neurological studies have, however, shown reduced cognitive and phonetic quality and function in patients with unilateral and bilateral asymptomatic carotid artery stenosis. Twenty-one RCTs comparing lone carotid artery stenting (CAS) and CEA informed the American Heart Association guidelines, which declared CAS comparable with CEA for symptomatic and asymptomatic carotid stenosis (CS). However, the risk of death/stroke for CAS alone is double that for CEA alone in the acute phase following onset of symptoms, while CEA alone is associated with a doubled risk of myocardial infarction.

    The vestibulo-ocular reflex (VOR) of five patients with surgically confirmed unilateral peripheral vestibular lesions is evaluated. Testing used both earth vertical axis (EVA) and earth horizontal axis (EHA) yaw rotation. Results indicated that the patients had short VOR time constants, asymmetric responses to both EVA and EHA rotation, and normal EHA modulation components. These findings suggest that unilateral peripheral vestibular loss causes a shortened VOR time constant even with the addition of dynamic otolithic stimulation and causes an asymmetry in semicircular canal-ocular reflexes and one aspect of otolith-ocular reflexes.

    Patients with complex coronary lesions undergoing percutaneous coronary intervention (PCI) have more major adverse cardiac events (MACE) than do those with simpler cases. Therefore, intensive antiplatelet therapy might be needed in these patients. A total of 127 patients with complex lesions undergoing PCI in the Second Hospital of Tianjin Medical University from October 2012 to April 2014 were randomized to receive either dual (aspirin plus clopidogrel, DAPT, n = 66), or triple antiplatelet therapy (aspirin plus clopidogrel plus cilostazol; TAPT, n = 61). Patients in the TAPT group received low-dose cilostazol (100 mg loading, followed with 50 mg twice per day) for 3-6 months. The primary endpoint was composite MACE. The complex coronary target lesions were defined as at least one of the following: left main disease; severe 3-vessel disease; chronic total occlusion lesions; true bifurcation lesion; ostial lesions; severe calcified lesions; and highly thrombotic lesions. The two groups had similar baseline clinical and angiographic characteristics. One-year clinical outcomes showed that the TAPT group had significantly lower incidences of myocardial infarction (1.6% vs 13.6%, P = 0.018) and MACE (1.6% vs 16.7%, P = 0.004) than DAPT group. The DAPT group had two cases of stent thrombosis, while the TAPT group did not. Furthermore, adjunctive low-dose cilostazol didn't significantly increase the incidence of bleeding events (26.2% vs 19.7%, P = 0.381) regardless of major (4.9% vs 4.5%, P = 0.921) or minor (21.3% vs 15.2%, P = 0.368) bleeding events. In conclusion, low-dose adjunctive cilostazol seems superior to dual antiplatelet therapy in reducing recurrent ischemic events in patients with complex coronary lesions and the two test groups have a similar incidence of bleeding events.

    Background The use of dexmedetomidine may have benefits on the clinical outcomes of cardiac surgery. We conducted a meta-analysis comparing the postoperative complications in patients undergoing cardiac surgery with dexmedetomidine versus other perioperative medications to determine the influence of perioperative dexmedetomidine on cardiac surgery patients. Methods Randomized or quasi-randomized controlled trials comparing outcomes in patients who underwent cardiac surgery with dexmedetomidine, another medication, or a placebo were retrieved from EMBASE, PubMed, the Cochrane Library, and Science Citation Index. Results A total of 1702 patients in 14 studies met the selection criteria among 1,535 studies that fit the research strategy. Compared to other medications, dexmedetomidine has combined risk ratios of 0.28 (95% confidence interval [CI] 0.15, 0.55, P = 0.0002) for ventricular tachycardia, 0.35 (95% CI 0.20, 0.62, P = 0.0004) for postoperative delirium, 0.76 (95% CI 0.55, 1.06, P = 0.11) for atrial fibrillation, 1.08 (95% CI 0.74, 1.57, P = 0.69) for hypotension, and 2.23 (95% CI 1.36, 3.67, P = 0.001) for bradycardia. In addition, dexmedetomidine may reduce the length of intensive care unit (ICU) and hospital stay. Conclusions This meta-analysis revealed that the perioperative use of dexmedetomidine in patients undergoing cardiac surgery can reduce the risk of postoperative ventricular tachycardia and delirium, but may increase the risk of bradycardia. The estimates showed a decreased risk of atrial fibrillation, shorter length of ICU stay and hospitalization, and increased risk of hypotension with dexmedetomidine. PMID:27049318

    Abstract The aim of the study is to utilize electrical impedance tomography (EIT) to guide positive end-expiratory pressure (PEEP) and to optimize oxygenation in patients undergoing laparoscopic abdominal surgery. Fifty patients were randomly assigned to the control (C) group and the EIT (E) group (n = 25 each). We set the fraction of inspired oxygen (FiO2) at 0.30. The PEEP was titrated and increased in a 2-cm H2O stepwise manner, from 6 to 14 cm H2O. Hemodynamic variables, respiratory mechanics, EIT images, analysis of blood gas, and regional cerebral oxygen saturation were recorded. The postoperative pulmonary complications within the first 5 days were also observed. We chose 10 cm H2O and 8 cm H2O as the “ideal” PEEP for the C and the E groups, respectively. EIT-guided PEEP titration led to a more dorsal shift of ventilation. The PaO2/FiO2 ratio in the E group was superior to that in the C group in the pneumoperitoneum period, though the difference was not significant (330 ± 10 vs 305.56 ± 4 mm Hg; P = 0.09). The C group patients experienced 8.7% postoperative pulmonary complications versus 5.3% among the E group patients (relative risk 1.27, 95% confidence interval 0.31–5.3, P = 0.75). Electrical impedance tomography represents a new promising technique that could enable anesthesiologists to assess regional ventilation of the lungs and optimize global oxygenation for patients undergoing laparoscopic abdominal surgery.

    Background: Renal failure is a major public health problem in the world. These patients experience high levels of psychological tension, anxiety, and depression, which leads to their lowered quality of life, increased health care costs, and early mortality. Due to medication side effects in these patients, non-medicational methods are more in demand now. This study aimed to investigate the effect of hope therapy on depression, anxiety, and stress among the patients undergoing hemodialysis. Materials and Methods: This is a clinical trial. Fifty patients undergoing hemodialysis were selected. Patients were assigned to two groups of hope therapy and placebo. Intervention of hope therapy was administered for 60–90 min during dialysis sessions once a week for eight sessions. In the placebo group, non-specific intervention was administered with the same number of sessions. Depression, Anxiety, and Stress scale (DASS)-21 questionnaire was completed at the end of the last session and 4 weeks later. Data were analyzed by paired t-test, repeated measures analysis of variance (ANOVA), and least significant difference (LSD) post hoc test through SPSS 18. Results: There was a significant difference in mean scores of depression, anxiety, and stress in hope therapy group before, immediately after, and 1 month after intervention (P < 0.05), while there was no significant difference in mean scores of depression, anxiety, and stress before and immediately after intervention in the placebo group. Changes in mean scores of depression, anxiety, and stress were significantly higher in hope therapy group compared to placebo (P < 0.05). Conclusions: The obtained results showed that hope therapy is effective on reduction of depression, anxiety, and stress. PMID:26793255

    Objectives: Recent investigations have shown that serotonergic antidepressant (SAd) use may increase the risk of peri-operative bleeding events. Our objective was to evaluate the possibility of a similar association in patients undergoing radiologic breast biopsies. Methods: We used data from 3890 patients undergoing 6300 biopsy procedures between January 2011 and October 2014 in the Breast Clinic of McGill University Health Centre, Montreal, Canada. In this case-control study, cases were patients reported to have abnormal bleeding during their biopsy by board-certified radiologists. A control group of nonbleeders was selected using matching according to age and type of biopsy. The correlation between abnormal bleeding and SAd use was assessed using bivariate and multivariate statistical analyses. Results: There were 97 patients with abnormal bleeding and 137 matched controls; 10 bleeders (cases) were on SAds (7 citalopram, 3 paroxetine) while only 1 nonbleeder (control group) was on a SAd (low-dose sertraline, 25 mg/day). SAds were significantly associated with increased bleeding risk (10.3% versus 0.7%, Fisher’s Exact p = 0.001). Moreover, after adjusting for confounding factors (age, type of biopsy, size of biopsy, needle caliber, pathology result and nonsteroidal anti-inflammatory drug use, multivariate logistic regression confirmed that SAds were associated with elevated bleeding risk (16.2, 95% confidence interval 1.87–140.1, p = 0.01). Conclusions: This is the first study demonstrating increased bleeding events in breast biopsy patients using SAds. Clinicians should be aware that SAds may be associated with peri-operative bleeding risk, even in relatively minor procedures such as breast biopsies. PMID:26834966

    This study evaluated intraoperative complications and postoperative outcomes of gynecologic oncology patients undergoing robotic-assisted (RA) laparoscopic procedures in a university setting. A retrospective chart review evaluated all gynecologic oncology patients at the University of Alabama at Birmingham who underwent attempted RA procedures between August 2006 and October 2011. Patient demographics, medical/surgical history, intraoperative complications, postoperative outcomes, conversion rates, readmission rates, and length of stay were examined. Total complication rates were assessed over time for each surgeon. 681 patients underwent planned RA procedures by seven gynecologic oncologists. The mean body mass index was 33.5 kg/m(2) (range 16.6-71.0 kg/m(2)). 61.4 % were diagnosed with malignancy. The most common procedure was RA hysterectomy with unilateral/bilateral salpingo-oophorectomy (37.2 %). Robotic staging was performed in 291 patients (45.1 %). Mean estimated blood loss was 75 ml (range 5-700 ml). 36 patients (5.3 %) were converted to laparotomy. The most common reason for conversion was adhesions (30.1 %), followed by uterine size (22.2 %). In 107 cases, a surgical modification was required for specimen removal including mini-laparotomy (24), extension of accessory port (36), morcellation (9), and difficult vaginal delivery (38). 3.7 % had intraoperative complications; 6 patients had a cystotomy and 5 had a vascular injury. Postoperatively, 20 patients had a febrile episode, 9 had wound complications, and 3 had a vaginal cuff dehiscence. 27 (4.2 %) patients were readmitted within 30 days. Complication rates and conversion rates were similar per surgeon. Total complication rates for evaluable surgeons were similar between the first 10 cases and subsequent 50 cases. Although patients undergoing RA procedures in a university setting are high risk, the conversion rate to laparotomy is low and intraoperative and postoperative complications are

    This study investigated if free T4 and TSH concentrations or thyroid function categories were associated with prevalent CHD and the severity of coronary atherosclerosis in a population undergoing coronary angiography. This was a cross-sectional study including 1799 patients who were consecutively admitted and underwent coronary angiography. We evaluated the severity of coronary atherosclerosis using Gensini score. In the entire study population, free T4 level was inversely associated with prevalent CHD (OR = 0.95, 95% CI 0.91–0.99, P = 0.01) and the natural log-transformed Gensini score (ln(Gensini score)) (β = −0.03, 95% CI −0.05–−0.01, P = 0.005). The odds of CHD increased gradually across hyperthyroidism, subclinical hypothyroidism, and overt hypothyroidism groups using the euthyroid group as the reference, and the trend is borderline significant (P for trend = 0.051). When comparing to the euthyroid group, ln(Gensini score) of the overt hypothyroidism group was significantly higher (P = 0.009), but the trend was not significant (P for trend = 0.08). A significant association of thyroid function with CHD or ln(Gensini score) in euthyroid patients was not observed. The present study demonstrated an association of thyroid function with prevalent CHD and the severity of coronary atherosclerosis in a population undergoing coronary angiography. However, this association was not observed in euthyroid individuals. PMID:26770196

    Background Liver failure following liver surgery is caused by an insufficient functioning remnant cell mass. This can be due to insufficient liver volume and can be aggravated by additional cell death during or after surgery. The aim of this study was to elucidate the causes of hepatocellular injury in patients undergoing liver resection. Methods Markers of hepatocyte injury (AST, GSTα, and L-FABP) and inflammation (IL-6) were measured in plasma of patients undergoing liver resection with and without intermittent inflow occlusion. To study the separate involvement of the intestines and the liver in systemic L-FABP release, arteriovenous concentration differences for L-FABP were measured. Results During liver manipulation, liver injury markers increased significantly. Arterial plasma levels and transhepatic and transintestinal concentration gradients of L-FABP indicated that this increase was exclusively due to hepatic and not due to intestinal release. Intermittent hepatic inflow occlusion, anesthesia, and liver transection did not further enhance arterial L-FABP and GSTα levels. Hepatocyte injury was followed by an inflammatory response. Conclusions This study shows that liver manipulation is a leading cause of hepatocyte injury during liver surgery. A potential causal relation between liver manipulation and systemic inflammation remains to be established; but since the inflammatory response is apparently initiated early during major abdominal surgery, interventions aimed at reducing postoperative inflammation and related complications should be started early during surgery or beforehand.

    Background Routine preoperative laboratory testing for ambulatory surgery is not recommended. Methods Patients who underwent elective hernia repair (N = 73,596) were identified from the National Surgical Quality Improvement Program (NSQIP) database (2005–2010). Patterns of preoperative testing were examined. Multivariate analyses were used to identify factors associated with testing and postoperative complications. Results A total of 46,977 (63.8%) patients underwent testing, with at least one abnormal test recorded in 61.6% of patients. In patients with no NSQIP comorbidities (N = 25,149) and no clear indication for testing, 54% received at least one test. In addition, 15.3% of tested patients underwent laboratory testing the day of the operation. In this group, surgery was done despite abnormal results in 61.6% of same day tests. In multivariate analyses, testing was associated with older age, ASA (American Society of Anesthesiologists) class >1, hypertension, ascites, bleeding disorders, systemic steroids, and laparoscopic procedures. Major complications (reintubation, pulmonary embolus, stroke, renal failure, coma, cardiac arrest, myocardial infarction, septic shock, bleeding, or death) occurred in 0.3% of patients. After adjusting for patient and procedure characteristics, neither testing nor abnormal results were associated with postoperative complications. Conclusions Preoperative testing is overused in patients undergoing low-risk, ambulatory surgery. Neither testing nor abnormal results were associated with postoperative outcomes. On the basis of high rates of testing in healthy patients, physician and/or facility preference and not only patient condition currently dictate use. Involvement from surgical societies is necessary to establish guidelines for preoperative testing. PMID:22868362

    OBJECTIVES To better understand the risk of short-term complications associated with perioperative intravesical mitomycin-C (MMC) therapy for patients undergoing endoscopic management of non-muscle invasive bladder cancer (NMIBC). METHODS AND MATERIALS Using an institutional database of patients with bladder cancer, we performed a retrospective case-control study of patients receiving perioperative MMC after tumor resection (2008–2012). MMC cases were matched by clinical stage to controls receiving endoscopic resection alone. Demographic information, clinicopathologic details and outcomes were compared between groups. Outcomes of interest included overall, genitourinary (GU) and major complications. Chi-square tests and multivariable logistic regression were used to evaluate associations between patient characteristics, clinical factors, exposure to MMC and outcomes of interest. RESULTS One-hundred sixteen patients treated with MMC were matched to 116 controls. Patients receiving MMC were younger (p=0.04) and more likely to have invasive disease (i.e., T1 or greater) (23% vs. 15%, p=0.02). Complications were more frequent among patients who were treated with MMC (34.5% vs. 19.8%, OR 2.89, 95% CI 1.43–5.81). The most common complication among MMC patients that required medical management was dysuria (17%). Major complications were more common among MMC patients (5.2% vs. 0.9%), but this difference did not reach statistical significance (p=0.11). CONCLUSIONS Use of MMC is associated with a greater odds of complications compared to controls. Patients should be counseled regarding both the benefits and potential risks of perioperative intravesical MMC. Continued research is required to understand the safety implications associated with the use of perioperative, intravesical MMC. PMID:23787296

    We conducted a phase II trial investigating the impact of fractionated hematopoietic cell infusions on engraftment kinetics and symptom burden in patients with plasma cell myeloma (PCM) undergoing autologous hematopoietic cell transplant (AHCT). We hypothesized that multiple hematopoietic cell infusions would reduce duration of neutropenia and enhance immune recovery resulting in a better tolerated procedure. Twenty-six patients received high-dose melphalan followed by multiple cell infusions (Days 0, +2, +4, +6) and were compared to PCM patients (N = 77) who received high-dose melphalan and a single infusion (Day 0) (concurrent control group). The primary endpoint was number of days with ANC <500K/mcL. Symptom burden was assessed using the MSK-modified MD Anderson Symptom Inventory. Median duration of neutropenia was similar in study (4 days, range 3-5) and control patients (4 days, range 3-9) (p = 0.654). There was no significant difference in the number of red cell or platelet transfusions, days of fever, diarrhea, antibiotics, number of documented infections, or length of admission. Symptom burden surveys showed that AHCT was well-tolerated in both study and control patients. We conclude that fractionated stem cell infusions following high-dose melphalan do not enhance engraftment kinetics or significantly alter patients' clinical course following AHCT in PCM.

    Background The aim of the study was to clarify the frequency of colorectal neoplasm (CRN) complicating superficial esophageal squamous cell carcinoma (ESCC) and the need for colonoscopy. Methods We retrospectively reviewed 101 patients who had undergone initial endoscopic resection (ER) for superficial ESCC. Control group participants were age- and sex-matched asymptomatic subjects screened at our hospital over the same period of time. Advanced adenoma was defined as an adenoma ≥10 mm, with villous features, or high-grade dysplasia. Advanced CRN referred to advanced adenoma or cancer. We measured the incidence of advanced CRN in superficial ESCC and controls, and we compared the characteristics of superficial ESCC patients with and without advanced CRN. Results In the superficial ESCC group, advanced CRNs were found in 17 patients (16.8%). A history of smoking alone was found to be a significant risk factor of advanced CRN [odds ratio 6.02 (95% CI 1.30-27.8), P=0.005]. Conclusion The frequency of synchronous advanced CRN is high in superficial ESCC patients subjected to ER. Colonoscopy should be highly considered for most patients who undergo ER for superficial ESCC with a history of smoking, and is recommended even in superficial ESCC patients. PMID:27366032

    No survival advantage of autologous stem cell transplantation (ASCT) has been documented for patients older than 65 years, and in the era of thalidomide (Thalomid), bortezomib (Velcade), and lenalidomide (Revlimid), ASCT has a diminished role in the front-line treatment of older patients with myeloma. For these individuals and for those who cannot or choose not to undergo ASCT, the initial treatment regimens now recommended by both the National Comprehensive Cancer Network and the International Myeloma Working Group are melphalan (Alkeran)/prednisone/thalidomide (MPT), bortezomib/melphalan/prednisone (VMP), and lenalidomide/low-dose dexamethasone. Melphalan/prednisone should no longer be considered the reference treatment, although it may be appropriate for a small number of patients with serious comorbidity and/or poor performance status. Advantages of VMP over MPT include rapid response, high rates of complete response, patient compliance, and more extensive evidence of efficacy in patients with certain cytogenetic abnormalities. Lenalidomide/low-dose dexamethasone is particularly appropriate for patients with preexisting neurotoxicity and those who wish to postpone ASCT. Toxicity profiles differ among the newly established and emerging regimens, and oncology teams must take care to apply the appropriate risk management measures, including dose reduction where necessary.

    Clinical significance of diametrically polarized tumor-associated macrophages in gastric cancer has been elucidated in our previous study, whereas the role of cytokines that orchestrate tumor-associated macrophages polarization in gastric cancer remains elusive. The study aims to evaluate the prognostic value of colony-stimulating factor-1 expression in patients with gastric cancer. We examined the colony-stimulating factor-1 expression in tumor tissues by immunohistochemical staining in retrospectively enrolled 365 patients with gastric cancer undergoing gastrectomy at Zhongshan Hospital during 2008. Kaplan-Meier analysis and Cox regression models were used to evaluate the prognostic value of colony-stimulating factor-1 expression and its association with clinicopathological factors. A predictive nomogram by integrating colony-stimulating factor-1 expression with the TNM staging system was generated for overall survival evaluation of the patients. High colony-stimulating factor-1 expression predicted an unfavorable outcome in gastric cancer. The colony-stimulating factor-1 expression in tumor tissue could give a further discrimination for the prognosis of gastric cancer patients. Cox multivariate analysis identified the colony-stimulating factor-1 expression as an independent prognostic factor. The generated nomogram performed well in predicting the 3- and 5-year overall survival of gastric cancer patients.T he colony-stimulating factor-1 is a potential independent adverse prognosticator for gastric cancer patients, which could be integrated with the tumor-associated macrophages staging system to improve the predictive accuracy for overall survival, especially in advanced tumors.

    There is increasing and consistent evidence concerning the association of systemic inflammation and poor outcome in patients with hepatocellular carcinoma (HCC). The aim of this study was to identify a superior inflammation-based prognostic scoring system for patients with HCC undergoing hepatectomy.We analyzed two independent cohorts of a total of 723 patients with HCC who underwent radical surgery between 2010 and 2012. The prognostic value of the inflammation scores, including the Glasgow Prognostic Score (GPS), modified GPS (mGPS), neutrophil-to-lymphocyte ratio, platelet lymphocyte ratio, prognostic index, and prognostic nutritional index, as well as the Barcelona Clinic Liver Cancer and Cancer of the Liver Italian Program staging systems was analyzed in a test cohort of 367 patients and validated in a validation cohort of 356 patients.A high score with the mGPS was associated with large tumor size, vascular invasion, and advanced clinical stage. Multivariate analysis showed that the mGPS was independently associated with overall survival and disease-free survival, and had a higher area under the curve value in comparison with other inflammation-based scores.The results of this study demonstrated that the mGPS is an independent marker of poor prognosis in patients with resectable HCC and is superior to other inflammation-based scores.

    The incidence and nature of acute secondary irradiation esophagitis was studied in a series of 38 patients undergoing 60Co teletherapy for carcinoma of the lung. Thirty-four patients were male and four female, with ages ranging from 38 to 78 years. The mediastinum being irradiated in the process, all the patients underwent endoscopy for signs of esophagitis and/or gastritis after a dose of 30-40 Gy was delivered to the esophagus. Eighteen patients complained of dysphagia, but only in 12 of them did endoscopy show esophagitis. Of the remaining patients without complaints five had endoscopic signs of esophagitis. Gastritis was found in 18 cases and confirmed histologically in 14. In 17 cases, esophagitis and/or gastritis were confirmed histologically. It is believed that there is a fairly close correlation among clinical, endoscopic, and histological findings to support the claim that esophagitis in these patients is radiation induced. However, the cause of gastritis is not well understood. Data in the literature suggest that nonsteroid anti-inflammatory agents can act as prophylactic means of preventing radiation esophagitis.

To ascertain the incidence of lymphedema in a hospital based population (in patients undergoing axillary dissection for breast cancer. 2. To determine the clinico-epidemilogical factors associated with the occurrence of lymphedema in these patients. For all patients undergoing axillary dissection, arm measurements were taken in the pre-& post-operative period from at least 3 sites; one in the arm, forearm and wrist (points fixed in reference to fixed bony landmarks). Patients included in this study were followed up for at least 12 months. Circumference difference of more than 5% was taken as mild lymphedema; more than 10% as moderate lymphedema and more than 15% as severe lymphedema. Data was analyzed using SPSS 11.0 statistical software. Of the 231 patients in this study mean age was 51.2 years, majority were housewives (71.9%) and postmenopausal (58.5%). Modified radical mastectomy (MRM), was performed on 203 (87.9%) patients. 57.2% patients had positive lymph nodes. The mean number of positive nodes was 6.52. Majority of the patients received chemo and radio therapy. Overall incidence of lymphedema was 41.1%. The definition of 5-10% increase as mild lymphedema may be a bit severe as in most patients with this increase, lymphedema is not clinically apparent. The incidence of moderate and severe lymphedema in our series is only 7.4%. The incidence of clinically significant lymphedema (moderate to severe lymphedema & symptomatic mild lymphedema) was 16.8%. Only axillary irradiation and pathological nodal status (pN3) emerged as significant risk factors for lymphedema development on multivariate analysis. Lymphedema once established is difficult to treat. Combination of axillary dissection with radiation and more nodal positivity seems to

    Objective: Compare the prognosis and complications of diabetic and non-diabetic patients undergoing isolated coronary artery bypass surgery at a hospital with a high surgical volume. Methods: Data of patients who underwent coronary artery bypass surgery from June 2009 to July 2010 were analyzed. We selected diabetic and non-diabetic patients and evaluated their postoperative and long-term prognosis based on clinical complications. To reduce the disparity within the sample, statistical analyses were performed using propensity scores. Results: We included 2,688 patients who underwent coronary artery bypass surgery; 36% of them had diabetes, their mean age was 62.1±9.49 years and 70% (1,884) of them were men. Patients with diabetes were older (63±9 years vs. 61±10 years; P<0.001), more often obese (BMI>25 kg/m2: 70.7% vs. 64.5%; P<0.001), dyslipidemic (50.4% vs. 41.1%; P<0.001), hypertensive (89.2% vs. 78.7%; P<0.001), and presented chronic renal failure (8.3% vs. 3.8%; P<0.001). They also presented higher rates of acute renal failure (5.6% vs. 2.7%, P<0.001), infection (11.4% vs. 7.2%, P<0.001) and mortality after one year (9.1% vs. 5.6%, P<0.001). Pneumonia was more common among patients with diabetes (7.7% vs. 4.0%, P<0.001). According to propensity scoring, 430 patients (215 diabetics and 215 non-diabetics) had a mean age of 61.3±8.97 years, and 21.2% (91 of 430) were women. However, diabetes was not an independent factor for poor prognosis. Conclusion: Patients with diabetes were at higher risk for postoperative complications and mortality after undergoing coronary artery bypass surgery. However, diabetes did not explain the poor prognosis of these patients after pairing this factor with the propensity score. PMID:27074269

    Summary Introduction: Lateral osteotomies play an important role in rhinoplasty and can be performed with different techniques. Objective: To compare the results of narrowing of the nasal dorsum and base through 2 types of lateral osteotomy: continuous and microperforating. Method: We selected 74 patients undergoing rhinoplasty: 37 patients underwent lateral continuous osteotomy and the other 37 underwent microperforating osteotomy, all performed by the same surgeon. We analyzed frontal photography from the pre- and post-operative (6 months) periods, evaluating the width of the nasal dorsum and base. This was a retrospective study. Results and Conclusion: Using Student's t-test, statistical analysis concluded that there was a statistically significant difference in the post-operative narrowing of the nasal dorsum and base following both osteotomy techniques, and there was no statistically significant difference between the 2 techniques.

    Acute esophageal necrosis is uncommon in the literature. Its etiology is unknown, although cardiovascular disease, hemodynamic compromise, gastric outlet obstruction, alcohol ingestion, hypoxemia, hypercoagulable state, infection, and trauma have all been suggested as possible causes. A 67-year-old female underwent a coronary angiography (CAG) for evaluation of chest pain. CAG findings showed coronary three-vessel disease. We planned percutaneous coronary intervention (PCI). Coronary arterial dissection during the PCI led to sudden hypotension. Six hours after the index procedure, the patient experienced a large amount of hematemesis. Emergency gastrofibroscopy was performed and showed mucosal necrosis with a huge adherent blood clot in the esophagus. After conservative treatment for 3 months, the esophageal lesion was completely improved. She was diagnosed with acute esophageal necrosis. We report herein a case of acute esophageal necrosis occurring in a patient undergoing percutaneous coronary intervention. PMID:24851074

    Summary Introduction: The merging of medicine with information technology facilitates the retrieval of stored data, aiding the conduct of research with greater scientific rigor. Studies in the field of otorhinolaryngology, specifically in the area of laryngology and voice, are of fundamental importance, since 70% of the economically active need their voice to work. Objective: To create a computerized protocol of the diseases of the larynx, apply and validate it, and use it to evaluate patients undergoing laryngoscopic microsurgery of the larynx. Method: We created a database of ENT diseases through a literature review of textbooks and scientific articles. Next, we computerized the data and incorporated it into the SINPE©, creating a master protocol (ENT diseases) and a specific protocol (laryngeal diseases). Data were collected prospectively from patients undergoing laryngeal microsurgery in the ENT Hospital of Paraná. The collected data were analyzed with graphs through the SINPE© Analyzer module. Results: We evaluated 245 patients aged 9–79 years, and determined that 36.61% (93 patients) underwent surgery for the presence of polyps on the vocal folds, 12.6% (32) underwent surgery for papillomatosis, and 11.83% (29) underwent surgery for intracordal cysts. Conclusions: The creation of an electronic database of clinical ENT diseases was feasible. We were also able to implement and validate the protocol. The database may be released to physicians involved in clinical data collection and retrieval of information to conduct scientific research in an organized manner. The most common laryngeal disorders identified were polyps, papilloma, and intracordal cysts. PMID:25991956

    Background Bilirubin has emerged as an important endogenous antioxidant molecule, and increasing evidence shows that bilirubin may protect against atherosclerosis. The SYNTAX score has been developed to assess the severity and complexity of coronary artery disease. The aim of this study was to evaluate whether serum bilirubin levels are associated with SYNTAX scores and whether they could be used to predict future cardiovascular events in patients undergoing coronary intervention. Methods Serum bilirubin levels and other blood parameters in patients with at least 12-h fasting states were determined. The primary endpoint was any composite cardiovascular event within 1 year, including death, nonfatal myocardial infarction, and target-vessel revascularization. Results In total, 250 consecutive patients with stable coronary artery disease (mean age 70 ± 13) who had received coronary intervention were enrolled. All study subjects were divided into two groups: group 1 was defined as high SYNTAX score (> 22), and group 2 was defined as low SYNTAX score (≤ 22). Total bilirubin levels were significantly lower in the high SYNTAX score group than in the low SYNTAX score group (0.51 ± 0.22 vs. 0.72 ± 0.29 mg/dl, p < 0.001). By multivariate analysis, serum total bilirubin levels were identified as an independent predictor for high SYNTAX score (adjusted odds ratio: 0.28, 95% confidence interval 0.04-0.42; p = 0.004). Use of the Kaplan-Meier analysis demonstrated a significant difference in 1-year cardiovascular events between high (> 0.8 mg/dl), medium (> 0.5, ≤ 0.8 mg/dl), and low (≤ 0.5 mg/dl) bilirubin levels (log-rank test p = 0.011). Conclusions Serum bilirubin level is associated with SYNTAX score and predicts future cardiovascular events in patients undergoing coronary intervention. PMID:27471354

    AIM: To ascertain current surgeon practice in the United Kingdom National Health Service for the management of patients undergoing lumbar spinal fusion surgery. METHODS: Descriptive survey methodology utilised an online questionnaire administered through SurveyMonkey. Eligible participants were all surgeons currently carrying out lumbar spinal fusion surgery in the National Health Service. Two previous surveys and a recent systematic review informed questions. Statistical analyses included responder characteristics and pre-planned descriptive analyses. Open question data were interpreted using thematic analysis. RESULTS: The response rate was 73.8%. Most surgeons (84%) were orthopaedic surgeons. Range of surgeon experience (1-15 years), number of operations performed in the previous 12 mo (4-250), and range of information used to predict outcome was broad. There was some consistency of practice: most patients were seen preoperatively; all surgeons ensured patients are mobile within 3 d of surgery; and there was agreement for the value of post-operative physiotherapy. However, there was considerable variability of practice: variability of protocols, duration of hospital stay, use of discharge criteria, frequency and timing of outpatient follow up, use of written patient information and outcome measures. Much variability was explained through patient-centred care, for example, 62% surgeons tailored functional advice to individual patients. CONCLUSION: Current United Kingdom surgeon practice for lumbar spinal fusion is described. The surgical procedure and patient population is diverse, and it is therefore understandable that management varies. It is evident that care should be patient-centred. However with high costs and documented patient dissatisfaction it is important that further research evaluates optimal management. PMID:26191495

    Purpose: To evaluate the patterns and timing of initial recurrence in patients with Hodgkin's lymphoma (HL) who subsequently underwent high-dose chemotherapy with autologous stem cell transplantation to enhance our understanding of the natural history of this disease and its modern treatment strategies and to direct approaches to disease surveillance. Methods and Materials: The records of 69 patients with HL who had undergone high-dose chemotherapy with autologous stem cell transplantation in our center between May 1992 and June 2006 were analyzed. The initial diagnosis had been made between April 1982 and January 2005 at a median patient age of 33 years (range, 19-65). The patients were segregated according to the initial stage (Stage I-II vs. III-IV). Results: Early-stage HL patients developed a relapse at a median of 2.1 years (range, 0.5-10.3), with 91% of relapses at the initial disease site, 71% of which (65% overall) were only in previously involved sites. Advanced-stage HL patients developed a relapse at a median of 1.5 years (range, 0.6-10.5), with 97% at the initial site, 71% of which (69% overall) were only in previously involved sites. Single-site relapses occurred in 47% of early- vs. 26% of advanced-stage patients, and extranodal relapses occurred in 12% of early- vs. 31% of advanced-stage patients. Conclusions: Almost all patients with HL who develop relapse and subsequently undergo high-dose chemotherapy with autologous stem cell transplantation initially developed recurrence in previously involved disease sites. Early-stage HL relapses often occurred in single sites, and advanced-stage disease relapses were more likely in multiple and extranodal sites. The interval to recurrence was brief, suggesting that the frequency of screening should be the greatest in the early post-therapy years.

    Background In contrast to the developed nations, invasive cervical cancer (ICC) is the most common womens malignancy in Kenya and many other locations in sub-Saharan Africa. However, studies on survival from this disease in this area of the world are severely restricted by lack of patient follow-up. We now report a prospective cohort study of ICC in Kenyan women analysing factors affecting tumour response and overall survival in patients undergoing radiotherapy. Methods and Findings Between 2008 and 2010, 355 patients with histologically confirmed ICC were recruited at the Departments of Gynaecology and Radiotherapy at Kenyatta National Hospital (KNH). Structured questionnaires were completed recording socio-demographics, tumour response and overall survival following treatment with combinations of external beam radiation (EBRT), brachytherapy and adjuvant chemotherapy. Of the 355 patients, 42% (146) were lost to follow-up while 18% (64) died during the two year period. 80.5% of patients presented with advanced stage IIB disease or above, with only 6.7% of patients receiving optimal combined EBRT, brachytherapy and adjuvant chemotherapy. Kaplan Meier survival curves projected two year survival at <20%. Conclusion Cervical cancer is preventable yet poverty, poor education, lack of cancer awareness coupled with an absence of regular screening programs, late patient presentation, sub-optimal diagnosis and treatments are major factors contributing to the alarmingly low survival rate of cervical cancer patients in Kenya. It is concluded that simple cost-effective changes in clinical practice could be introduced which would have a marked impact on patient survival in this setting. PMID:24205226

    Malnutrition occurs frequently in patients with cancer. Indeed, a variety of nutritional and tumor-related factors must be taken into account in these patients. Recognizing this relationship, we aimed to prospectively evaluate the risk factors that influence weight loss in patients undergoing radiotherapy with oral nutritional supplementation and dietetic counseling. Weight loss of 74 patients during radiotherapy and 1 month after treatment was analyzed. Parameters such as age, gender, tumor location, tumor stage, Eastern Cooperative Oncology Group performance status (ECOG PS) score, and the use of chemotherapy were analyzed to evaluate their influence on weight loss. All patients underwent oral nutritional supplementation and dietetic counseling. Forty-six (65.7%) patients lost weight, with a mean weight loss of (4.73 ± 3.91) kg, during radiotherapy. At 1 month after treatment, 45 (66.2%) patients lost weight, presenting a mean weight loss of (4.96 ± 4.04) kg, corresponding to a (6.84 ± 5.24)% net reduction from their baseline weight. Head and neck cancer patients had a mean weight loss of (3.25 ± 5.30) kg, whereas the remaining patients had a mean weight loss of (0.64 ± 2.39) kg (P = 0.028) during radiotherapy. In the multivariate analysis, the head and neck tumor location (P = 0.005), use of chemotherapy (P = 0.011), and ECOG PS score of 2-3 (P = 0.026) were considered independent risk factors. Nutritional status and parameters, such as tumor location (especially the head and neck), the use of chemotherapy, and the ECOG PS score, should be evaluated before radiotherapy because these factors can influence weight loss during radiotherapy and 1 month after treatment.

    Treatment of patients with lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) may affect the quality of sexual function and ejaculation. The effect of new surgical procedures, which are currently available to treat BPH, on erection and ejaculation, has been poorly studied. This study aimed to assess the effect of thulium laser enucleation of the prostate (ThuLEP) on sexual function and retrograde ejaculation in patients with LUTS secondary to BPH. We performed a prospective study in 110 consecutive patients who had undergone ThuLEP to analyze changes in sexual function and urinary symptoms. To evaluate changes in erection and ejaculation, and the effect of urinary symptoms on the quality of life (QoL), five validated questionnaires were used: the ICIQ-MLUTSsex, MSHQ-EjD, International Index of Erectile Function 5, International Prognostic Scoring System (IPSS) questionnaire, and QoL index of the intraclass correlation coefficients. Patients also underwent IPSS and flowmetry to assess the outcome of flow. Patients were evaluated before surgery and 3-6 months after ThuLEP, whereas those with previous abdominal surgery were excluded. The patients' mean age was 67.83 years. Postoperative urinary symptoms improved after surgery. No significant differences in erectile function before and after surgery were observed. As compared with other techniques described in the literature, the percentage of patients with conserved ejaculation increased by 52.7% after ThuLEP. ThuLEP positively affects urinary symptoms and their effect on the QoL of patients as assessed by questionnaire scores. While endoscopic management of BPH (e.g. transurethral resection of the prostate) causes retrograde ejaculation in most patients, those who undergo ThuLEP have conserved ejaculation and erectile function.

    Pharmacoinvasive treatment is an acceptable alternative for patients with ST-segment elevation myocardial infarction (STEMI) in developing countries. The present study evaluated the influence of gender on the risks of death and major adverse cardiovascular events (MACE) in this population. Seven municipal emergency rooms and the Emergency Mobile Healthcare Service in São Paulo treated STEMI patients with tenecteplase. The patients were subsequently transferred to a tertiary teaching hospital for early (<24 h) coronary angiography. A total of 469 patients were evaluated [329 men (70.1%)]. Compared to men, women had more advanced age (60.2 ± 12.3 vs. 56.5 ± 11 years; p = 0.002); lower body mass index (BMI; 25.85 ± 5.07 vs. 27.04 ± 4.26 kg/m2; p = 0.009); higher rates of hypertension (70.7 vs. 59.3%, p = 0.02); higher incidence of hypothyroidism (20.0 vs. 5.5%; p < 0.001), chronic renal failure (10.0 vs. 8.8%; p = 0.68), peripheral vascular disease (PVD; 19.3 vs. 4.3%; p = 0.03), and previous history of stroke (6.4 vs. 1.3%; p = 0.13); and higher thrombolysis in myocardial infarction risk scores (40.0 vs. 23.7%; p < 0.001). The overall in-hospital mortality and MACE rates for women versus men were 9.3 versus 4.9% (p = 0.07) and 12.9 versus 7.9% (p = 0.09), respectively. By multivariate analysis, diabetes (OR 4.15; 95% CI 1.86-9.25; p = 0.001), previous stroke (OR 4.81; 95% CI 1.49-15.52; p = 0.009), and hypothyroidism (OR 3.75; 95% CI 1.44-9.81; p = 0.007), were independent predictors of mortality, whereas diabetes (OR 2.05; 95% CI 1.03-4.06; p = 0.04), PVD (OR 2.38; 95% CI 0.88-6.43; p = 0.08), were predictors of MACE. In STEMI patients undergoing pharmacoinvasive strategy, mortality and MACE rates were twice as high in women; however, this was due to a higher prevalence of risk factors and not gender itself.

    Context • Combined treatment with an extract of Lentinula edodes mycelia (LEM) and chemotherapy has been reported to improve quality of life (QOL) and immunological function in cancer patients. However, those effects have not been elucidated for patients receiving cancer immunotherapy. Objective • The present study intended to investigate the effects of oral LEM on QOL and immunological function in cancer patients receiving immunotherapy. Design • The research team designed an open-label, single-armed pilot study. Setting • The study took place at Bio-Thera Clinic, a facility associated with Tokyo Women's Medical University in Tokyo, Japan. Participants • The participants were 10 cancer patients undergoing cancer immunotherapy at Bio-Thera Clinic. Intervention • The participants received either dendritic cell (DC)-based cancer vaccine therapy or CD3-activated T-lymphocyte (CAT) therapy as immunotherapy. They received the immunotherapy only for the first 4 wk of the study, and then oral LEM (1800 mg/d) was added for the next 4 wk. Outcome Measures • Preintervention and at 4 and 8 wk after the start of the study, participants completed a QOL survey, and immunological parameters were measured. Results • Participants' QOL symptom scores increased (ie, worsened) by 5.1 ± 1.7 during the first 4 wk of treatment when they were receiving immunotherapy only, but it decreased (ie, improved) by -2.5 ± 1.6 during the next 4 wk when the immunotherapy was combined with the LEM, P < .05. The measurement of the immunological parameters during the 4 wk of immunotherapy combined with LEM showed that the amount of interferon-γ (IFN-γ) produced in the peripheral blood tended to increase as compared with that during the first 4 wk of immunotherapy only. The rise in IFN-γ was correlated with changes in several regulatory T cells (Tregs) (ie, forkhead box P3 [FOXP3]+/cluster of differentiation 4 [CD4]+ and transforming growth factor beta [TGF-β]).

    Objective To identify the characteristics of anesthesia and perioperative management for ankylosing spondylitis (AS) patients undergoing total hip arthroplasty (THA). Methods Totally 63 patients scheduled for single THA in PUMC Hospital from January 1st 2013 to June 1st 2015 were included in this retrospective analysis,among whom 21 patients were diagnosed of AS. The perioperative clinical data included:demographic data,American Society of Anesthesiologists (ASA) classification,medical history,airway assessment,preoperative laboratory examinations,electrocardiogram,pulmonary function tests,intubation information,operation time,intraoperative intake and output volume,postoperative hospital stay,and postoperative complications. Results Significantly fewer AS patients undergoing THA were evaluated as ASA classification I than non-AS patients (9.5% vs. 33.3%,P=0.041). AS patients had significantly higher level of preoperative high-sensitivity C-reactive protein [(17.0±14.8)mg/L vs.(4.3±7.1)mg/L,P<0.001],platelets [(275.0±71.3)×10(9)/L vs. (237.7±68.0)×10(9)/L,P=0.048] and neutrophils [(4.7±1.7)×10(9)/L vs. (3.9±1.4)×10(9)/L,P=0.044] and higher incidence of pulmonary function abnormality (42.9% vs.16.7%,P=0.024).More AS patients were induced with scoline (14.3% vs.0,P=0.012). More AS patients underwent THA with Mallampati classification 3 (28.6% vs.7.1%,P=0.022),reduced neck extension(47.6% vs.2.4%,P<0.001),Cormack-Lehane classification2(56.3% vs.15.4%,P=0.002)and 3 (18.8% vs.0,P=0.005),while much fewer AS patients had Cormack-Lehane classification1 (25.0% vs.84.6%,P<0.001).A variety of difficult airway tools were used in intubation (AS group:Macintosh laryngoscope:14%,Macintosh laryngoscope with stylet:38%,visualization laryngoscope:24%,visualization stylet:10% and fiber bronchoscope:14%;non-AS group:57%,24%,12%,5% and 2%,respectively).

    IMPORTANCE The common practices used in the perioperative care of patients undergoing septorhinoplasty are diverse and controversial. A consensus statement on the preferred clinical pathway in the perioperative treatment of patients undergoing septorhinoplasty has yet to be approached formally. OBJECTIVES To investigate the perioperative treatment of patients undergoing septorhinoplasty and to identify common practice patterns based on the preferences of leading facial plastic surgeons. DESIGN, SETTING, AND PARTICIPANTS We distributed an online survey to members of the American Academy of Facial Plastic and Reconstructive Surgery. Specifically, fellowship directors and academic contact members were anonymously polled and stratified by the number of septorhinoplasties performed annually. MAIN OUTCOME AND MEASURE A cohesive clinical guide to perioperative treatment after rhinoplasty. RESULTS Of the 92 members surveyed, 67 (73%) successfully completed the survey. The distribution of respondents included 43 academicians (64%) and 24 physicians in private practice (36%). Twenty-eight surgeons (42%) performed fewer than 50 rhinoplasties a year and 39 (58%), more than 50, representing 3510 to 4549 septorhinoplasties in total among respondents. Forty-four surgeons (66%) refrained from using any packing, and 41 (61%) used intranasal splints, with polymeric silicone splints the most popular of these (n = 24 [59%]). Sixty-six surgeons (99%) used external nasal splints, including 49 (74%) who used a thermoplastic splint and 49 (74%) who left the external nasal splint in place for 7 days or longer. The most common postoperative interventions to reduce edema and ecchymosis were elevation of the head of bed by 62 (93%), ice packs by 50 (75%), and Arnica montana by 33 (49%). Only 12 surgeons (18%) used postoperative corticosteroids to reduce edema. Fifty-six respondents (84%) prohibited participation in contact sports until at least 6 weeks after surgery.

    Uremic pruritus (UP), also known as chronic kidney disease-associated pruritus, is a common and disabling symptom in patients undergoing maintenance hemodialysis (MHD). The pathogenesis of UP is multifactorial and poorly understood. Outdoor air pollution has well-known effects on the health of patients with allergic diseases through an inflammatory process. Air pollution-induced inflammation could occur in the skin and aggravate skin symptoms such as pruritus or impair epidermal barrier function. To assess the role of air pollutants, and other clinical variables on uremic pruritus (UP) in HD patients, we recruited 866 patients on maintenance HD. We analyzed the following variables for association with UP: average previous 12-month and 24-month background concentrations for nitrogen dioxide (NO2) and carbon monoxide (CO), and suspended particulate matter of <2.5 μm (PM2.5). In a multivariate logistic regression, hemodialysis duration, serum ferritin levels, low-density lipoprotein levels, and environmental NO2/CO levels were positively associated with UP, and serum albumin levels were negatively associated with UP. This cross-sectional study showed that air pollutants such as NO2 and CO might be associated with UP in patients with MHD. PMID:27507591

    Both obesity (BMI over 30) and SAS are risks for Supper airway maintenance. We report an obese patient (BMI 33.5) with SAS who underwent awake craniotomy. Weight reduction was instructed 1 month before the operation, and the patient lost enough weight to use intraoperative MRI. Under general anesthesia, surgical pads containing 2% lidocaine with adrenaline were inserted into the nasal cavities. The patient's airway S was secured by i-gel® until dura was opened. A nasal airway was then inserted to confirm the upper airway patency and anesthetics were terminated The patient regained consciousness and started respiration. The i-gel® was removed. The nasal airway was changed to an RAE tracheal tube ; the tube was fixed above the vocal cords under bronchofiberscopic observation. Continuous positive airway pressure (CPAP) via RAE tube was started. Neither coughing nor epistaxis was observed.The RAE tube prevented glossoptosis and did not disturb speech mapping. Emergent endotracheal intubation was easily managed because the tube was close to the glottis. The RAE tube was removed and nasal CP AP was applied overnight Carefully prepared CP AP support via nasal RAE tube was practical in keeping upper airway patency for an obese patient complicated with SAS undergoing awake craniotomy.

    Patients with end-stage liver disease frequently have baseline coagulopathies. The international normalized ratio is in common use for the estimation of bleeding tendency in such patients, especially those undergoing an invasive procedure like cardiac catheterization. The practice of international normalized ratio measurement-followed by pharmacologic (for example, vitamin K or fresh frozen plasma) or nonpharmacologic intervention-is still debatable. The results of multiple randomized trials have shown the superiority of the radial approach over femoral access in reducing catheterization bleeding. This reduction in bleeding in turn decreases the risk and cost of blood-product transfusion. However, there is little evidence regarding the use of the radial approach in the end-stage liver disease patient population specifically. In this review, we summarize the studies that have dealt with cardiac catheterization in patients who have end-stage liver disease. We also discuss the role of the current measurements that are used to reduce the risk of bleeding in these same patients.

    Diabetes mellitus (DM) and hyperglycemia are associated with increased surgical morbidity and mortality. Hyperglycemia is a determinant of risk of surgical complications and should be addressed across the continuum of surgical care. While data support the need to address hyperglycemia in patients with DM in the ambulatory setting prior to surgery and in the inpatient setting, data are less certain about hyperglycemia occurring during the perioperative period-that part of the process occurring on the day of surgery itself. The definition of "perioperative" varies in the literature. This paper proposes a standardized definition for the perioperative period as spanning the time of patient admission to the preoperative area through discharge from the recovery area. Available information about the impact of perioperative hyperglycemia on surgical outcomes within the framework of that definition is summarized, and the authors' approach to standardizing perioperative care for patients with DM is outlined, including the special case of patients receiving insulin pump therapy. The discussion is limited to adult ambulatory non-obstetric patients undergoing elective surgical procedures under general anesthesia.

    Objective: Atrial fibrillation is the most common arrhythmia after cardiac surgery. Several studies have shown the impact of vitamin D on heart disease; however, there have been few studies for the incidence of AF and its relationship with vitamin D levels. According to the different results of these studies, we decided to evaluate the relation of plasma levels of vitamin D and postoperative atrial fibrillation in patients undergoing coronary artery bypass surgery (CABG). Methods: This cross-sectional study was performed on 50 patients after CABG surgery. Simple random sampling was done. Twenty five patients who developed AF within 48 hours after CABG with Cardiopulmonary bypass (CPB) were enrolled in the case group and 25 patients who did not develop AF within 48 hours after CABG with CPB were enrolled in the control group. Plasma levels of vitamin D in both groups of patients were recorded. Collected data were analyzed by the SPSS software version 17. Results: There was no significant difference in terms of demographic characteristics, comorbidities, lipid profile and kidney function between two groups. The mean plasma level of vitamin D was 27.4 ± 2.22 ng/ml in the case group and was 28.2 ± 1.18 ng/ml in the control group it (p= 0.803). Conclusions: Plasma levels of vitamin D were almost the same in both groups and there was no statistically significant difference between the groups with and without atrial fibrillation following CABG.

    Obesity represents a unique challenge in orthopaedic surgery, the impact of which is seen through all phases of injury: in the development of disease, during the operative procedure, and throughout the rehabilitation period. Given the high prevalence of obesity in the United States and around the world, this patient population represents a substantial proportion of patients in need of orthopedic care. The effects of this disease constrain both medical and financial resources. For obese patients undergoing orthopedic procedures, adequate steps must be taken to minimize the risks that occur before, during, and after surgical intervention. This literature review discusses the impact of obesity on arthroscopic procedures, with a focus on procedures involving the shoulder, hip, and knee. The management of obese patients during the perioperative period should address the specific concerns relating to these patients. Obesity is a risk factor for numerous comorbidities, is associated with surgical complications, and is a predictor of poor functional outcomes following arthroscopy. Efforts to minimize the negative impact of obesity on arthroscopic procedures are crucial. PMID:27578242

    Midazolam and propofol are widely used for the sedation of patients with serious mental and physical disabilities. However, we often experience difficulty in the management of airway and respiratory depression when using these sedatives. Dexmedetomidine (DEX) is being increasingly used as a sedative because of the lack of associated respiratory depression. Here we report anesthetic management with DEX in two patients with disability undergoing dental treatment To avoid movement during treatment, DEX was infused at the rate recommended in the package insert, with an initial administration at 6 μg x kg(-1) x hr(-1) for 10 min followed by maintenance infusion at 0.7 μg x kg(-1) x hr(-1). Although the infusion rate seemed to be sufficient for the patients, DEX was not effective and administration of additional sedatives was required. Further, respiratory depression, such as airway obstruction and increase in the concentration of end-tidal carbon dioxide, was observed even when DEX was used as the sole agent for inducing sedation. No remarkable change in hemodynamics was observed. Therefore, it is difficult to maintain the sedative state using DEX alone in patients with serious mental and physical disabilities in comparison with patients with no disability. PMID:27188121

    Perioperative management of patients with liver cirrhosis undergoing open heart surgery (3 males and 1 female, mean age 57.3 years) was evaluated. All 4 patients had NYHA class III acquired valvular heart disease accompanied by severe tricuspid regurgitation, and the operation was a redo operation in 3 of them. Preoperatively, the total serum bilirubin was 1.7 mg/dl, ICGR15 24.3 +/- 1.7%, and blood platelet count was 83,000 +/- 19,000/m3. The postoperative course was uneventful in 2 patients who maintained good cardiac function and did not require homologous blood transfusion. The other two patients who underwent a re-redo operation, sustained a large volume of hemorrhage, and required massive transfusion showed severe postoperative complications (respiratory failure in 1, multiple organ failure in 1). The stage of the disease improved to NYHA class I in all 3 patients who survived the operation. Comprehensive measures including avoidance of massive hemorrhage, preservation of the hepatic blood flow, resolution of hepatic congestion, and prevention of complications such as digestive tract bleeding, infections, and renal failure are considered to be needed for prevention of postoperative liver failure. Especially, sufficient surgical hemostasis and autologous platelet rich plasma were useful for prevention of massive hemorrhage.

    ABSTRACT Objective: To evaluate the incidence of premalignant lesions and cancer in endometrial polyps, in patients undergoing hysteroscopic polypectomy. Methods: The results of 1,020 pathological examinations of patients submitted to hysteroscopic polypectomy were analyzed, as well as their diagnostic and surgical hysteroscopy findings. As to their menstrual status, 295 (28.9%) patients were in menacme. Of the total, 193 (65.4%) presented abnormal uterine bleeding, and 102 (34.6%) were asymptomatic with altered endometrial echo on transvaginal ultrasound. Out of 725 (71.1%) postmenopausal patients, 171 (23.6%) were symptomatic (abnormal uterine bleeding), and 554 (76.4%) were asymptomatic with endometrial echo >5.0mm. Results: Twenty-one (2.0%) patients presented premalignant lesions in the polyps, 13 had simple glandular hyperplasia, of which 5 had no atypia, and eight presented atypia. Eight polyps presented focal area of complex hyperplasia: 4 with atypia and 4 without lesions. Cancer was diagnosed in 5 (0.5%) polyps. Of the 21 polyps that harbored premalignant lesions, 12 were interpreted as benign in diagnostic and surgical hysteroscopy. Of the polyps with cancer, 4 were also histeroscopically interpreted as normal. Conclusion: Symptomatic polyps in menacme and in all postmenopausal women should be resected and submitted to histopathological examination, since they may have a benign aspect, even when harboring areas of cellular atypia or cancer.

    ABSTRACT Objective To evaluate the vital capacity after two chest therapy techniques in patients undergoing abdominal surgical. Methods A prospective randomized study carried out with patients admitted to the Intensive Care Unit after abdominal surgery. We checked vital capacity, muscular strength using the Medical Research Council scale, and functionality with the Functional Independence Measure the first time the patient was breathing spontaneously (D1), and also upon discharge from the Intensive Care Unit (Ddis). Between D1 and Ddis, respiratory therapy was carried out according to the randomized group. Results We included 38 patients, 20 randomized to Positive Intermittent Pressure Group and 18 to Volumetric Incentive Spirometer Group. There was no significant gain related to vital capacity of D1 and Ddis of Positive Intermittent Pressure Group (mean 1,410mL±547.2 versus 1,809mL±692.3; p=0.979), as in the Volumetric Incentive Spirometer Group (1,408.3mL±419.1 versus 1,838.8mL±621.3; p=0.889). We observed a significant improvement in vital capacity in D1 (p<0.001) and Ddis (p<0.001) and in the Functional Independence Measure (p<0.001) after respiratory therapy. The vital capacity improvement was not associated with gain of muscle strength. Conclusion Chest therapy, with positive pressure and volumetric incentive spirometer, was effective in improving vital capacity of patients submitted to abdominal surgery. PMID:27462894

    Objective: Atrial fibrillation is the most common arrhythmia after cardiac surgery. Several studies have shown the impact of vitamin D on heart disease; however, there have been few studies for the incidence of AF and its relationship with vitamin D levels. According to the different results of these studies, we decided to evaluate the relation of plasma levels of vitamin D and postoperative atrial fibrillation in patients undergoing coronary artery bypass surgery (CABG). Methods: This cross-sectional study was performed on 50 patients after CABG surgery. Simple random sampling was done. Twenty five patients who developed AF within 48 hours after CABG with Cardiopulmonary bypass (CPB) were enrolled in the case group and 25 patients who did not develop AF within 48 hours after CABG with CPB were enrolled in the control group. Plasma levels of vitamin D in both groups of patients were recorded. Collected data were analyzed by the SPSS software version 17. Results: There was no significant difference in terms of demographic characteristics, comorbidities, lipid profile and kidney function between two groups. The mean plasma level of vitamin D was 27.4 ± 2.22 ng/ml in the case group and was 28.2 ± 1.18 ng/ml in the control group it (p= 0.803). Conclusions: Plasma levels of vitamin D were almost the same in both groups and there was no statistically significant difference between the groups with and without atrial fibrillation following CABG.

    The clinical course and aluminum status of 38 patients who had been receiving dialysis for at least eight years and were still undergoing dialysis in 1985 were evaluated. Twenty-nine had evidence of increased aluminum burden, although only three had evidence of overt aluminum toxicity, and nine did not have evidence of increased aluminum burden. The patients in both the high- and low-aluminum group were similar with regard to age, the cause of their renal failure, presence of hypertension or coronary artery disease, previous parathyroidectomy, and a number of biochemical parameters, along with the amount of prescribed aluminum. All patients were followed up for the next two years or until they died. The amount of ingested aluminum was reduced, and in selected patients, treatment with intermittent infusions of deferoxamine mesylate was instituted. There were no deaths in the low-aluminum group, but ten of 29 died in the high-aluminum group: seven of vascular disease and three of infection. In addition, morbidity as defined by hospitalization for coronary or cerebral vascular disease or infection occurred in only two of the nine patients in the low-aluminum group and in 19 of the 29 patients in the high-aluminum group. These observations imply that the occurrence of increased body aluminum, as suggested by aluminum blood levels or by results of bone biopsies in some patients, has an adverse effect on morbidity and mortality and should be considered as a possible independent risk factor in patients who are receiving long-term hemodialysis.

    Treatment of patients with lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) may affect the quality of sexual function and ejaculation. The effect of new surgical procedures, which are currently available to treat BPH, on erection and ejaculation, has been poorly studied. This study aimed to assess the effect of thulium laser enucleation of the prostate (ThuLEP) on sexual function and retrograde ejaculation in patients with LUTS secondary to BPH. We performed a prospective study in 110 consecutive patients who had undergone ThuLEP to analyze changes in sexual function and urinary symptoms. To evaluate changes in erection and ejaculation, and the effect of urinary symptoms on the quality of life (QoL), five validated questionnaires were used: the ICIQ-MLUTSsex, MSHQ-EjD, International Index of Erectile Function 5, International Prognostic Scoring System (IPSS) questionnaire, and QoL index of the intraclass correlation coefficients. Patients also underwent IPSS and flowmetry to assess the outcome of flow. Patients were evaluated before surgery and 3–6 months after ThuLEP, whereas those with previous abdominal surgery were excluded. The patients’ mean age was 67.83 years. Postoperative urinary symptoms improved after surgery. No significant differences in erectile function before and after surgery were observed. As compared with other techniques described in the literature, the percentage of patients with conserved ejaculation increased by 52.7% after ThuLEP. ThuLEP positively affects urinary symptoms and their effect on the QoL of patients as assessed by questionnaire scores. While endoscopic management of BPH (e.g. transurethral resection of the prostate) causes retrograde ejaculation in most patients, those who undergo ThuLEP have conserved ejaculation and erectile function.

  10. I-ONE therapy in patients undergoing total knee arthroplasty: a prospective, randomized and controlled study

    PubMed Central

    2012-01-01

    Background Total knee arthroplasty (TKA) is often associated with a severe local inflammatory reaction which, unless controlled, leads to persistent pain up to one year after surgery. Standard and accelerated rehabilitation protocols are currently being implemented after TKA, but no consensus exists regarding the long-term effects. Biophysical stimulation with pulsed electromagnetic fields (PEMFs) has been demonstrated to exert an anti-inflammatory effect, to promote early functional recovery and to maintain a positive long-term effect in patients undergoing joint arthroscopy. The aim of this study was to evaluate whether PEMFs can be used to limit the pain and enhance patient recovery after TKA. Methods A prospective, randomized, controlled study in 30 patients undergoing TKA was conducted. Patients were randomized into experimental PEMFs or a control group. Patients in the experimental group were instructed to use I-ONE stimulator 4hours/day for 60days. Postoperatively, all patients received the same rehabilitation program. Treatment outcome was assessed using the Knee Society Score, SF-36 Health-Survey and VAS. Patients were evaluated pre-operatively and one, two, six and 12 months after TKA. Joint swelling and Non Steroidal Anti Inflammatory Drug (NSAID) consumption were recorded. Comparisons between the two groups were carried out using a two-tail heteroschedastic Student’s t-test. Analysis of variance for each individual subject during the study was performed using ANOVA for multiple comparisons, applied on each group, and a Dunnet post hoc test. A p value < 0.05 was considered statistically significant. Results Pre-operatively, no differences were observed between groups in terms of age, sex, weight, height, Knee-Score, VAS, SF-36 and joint swelling, with the exception of the Functional Score. The Knee-Score, SF-36 and VAS demonstrated significantly positive outcomes in the I-ONE stimulated group compared with the controls at follow-ups. In the I

    Endotoxaemia is thought to occur in cardiac surgery using extracorporeal circulation (ECC) and a positive correlation has been proposed between the magnitude of endotoxaemia and risk for postoperative complications. We studied the effects of a new endotoxin adsorber device (Alteco LPS adsorber) in patients undergoing cardiac surgery with ECC, with special reference to safety and ease of use. Fifteen patients undergoing coronary artery bypass and/or valvular surgery were studied. In 9 patients, the LPS Adsorber was included in the bypass circuit between the arterial filter and the venous reservoir. Flow through the adsorber was started when the aorta was clamped and stopped at the end of perfusion. Flow rate was kept at 150 ml/min. Six patients served as controls with no adsorber in the circuit. Samples were taken for analysis of endotoxin, TNFalpha, IL-1beta and IL-6 as well as complement factors C3, C4 and C1q. Whole blood coagulation status was evaluated using thromboelastograpy (TEG) and platelet count. No adverse events were encountered when the adsorber was used in the circuit. Blood flow through the device was easily monitored and kept at the desired level. Platelet count decreased in both groups during surgery. TEG data revealed a decrease in whole blood clot strength in the control group while it was preserved in the adsorber group. Endotoxin was detected in only 2 patients and IL-1beta in 4 patients. IL-6 decreased in both groups whereas no change in TNF concentrations was found. C3 fell in both groups, but no changes wer found in C4 and C1q. The Alteco LPS adsorber can be used safely and is easy to handle in the bypass circuit. No complications related to the use of the adsorber were noted. The intended effects of the adsorber, i.e. removal of endotoxin from the blood stream could not be evaluated in this study, presumably due to the small number of patients and the relatively short perfusion times.

    Objective Biological markers for Alzheimer's disease (AD) will help clinicians make objective diagnoses early during the course of dementia. Previous studies have suggested that cell cycle dysregulation begins earlier than the onset of clinical manifestations in AD. Methods We examined the lymphocyte expression of cell cycle proteins in AD patients, dementia controls (DC), and normal controls (NC). One-hundred seventeen subjects (36 AD, 31 DC, and 50 NC) were recruited. The cell cycle proteins CDK2, CDK4, CDK6, cyclin B, and cyclin D were measured in peripheral lymphocytes. Cell cycle protein expression in the three groups was compared after adjusting for age and sex. Results The levels of cell cycle proteins CDK2, CDK4, CDK6, cyclin B, and cyclin D were significantly higher in AD patients than in the NC subjects. The DC group manifested intermediate levels of cell cycle proteins compared with the AD patients and the NC subjects. The present study indicates that cell cycle proteins are upregulated in the peripheral lymphocytes of AD patients. Conclusion Cell cycle dysregulation in peripheral lymphocytes may present a promising starting point for identifying peripheral biomarkers of AD. PMID:26766955

    Dementia in patients undergoing long-term dialysis has not been clearly defined; however, four different entities have been described. Uraemic encephalopathy is a complication of uraemia and responds well to dialysis. Dialysis encephalopathy syndrome, the result of acute intoxication of aluminium caused by the use of an aluminium-containing dialysate, was a common occurrence prior to 1980. However, using modern techniques of water purification, such acute intoxication can now be avoided. Dialysis-associated encephalopathy/dementia (DAE) is always associated with elevated serum aluminium levels. Pathognomonic morphological changes in the brain have been described, but the mechanism for the entry of aluminium into the CNS is incompletely understood. The mechanisms involved in the pathogenesis of the neurotoxicity associated with aluminium are numerous. Although only a very small fraction of ingested aluminium is absorbed, the continuous oral aluminium intake from aluminium-based phosphate binders, and also of dietary or environmental origin, is responsible for aluminium overload in dialysis patients. Age-related dementia, especially vascular dementia, occurs in patients undergoing long-term dialysis as frequently as it does in the general population. The differential diagnoses of dialysis-associated dementias should include investigation for metabolic encephalopathies, heavy metal or trace element intoxications, and distinct structural neurological lesions such as subdural haematoma, normal pressure hydrocephalus, stroke and, particularly, hypertensive encephalopathy and multi-infarct dementia. To prevent DAE, dietary training programmes should aim to achieve the lowest phosphate intake and pharmacological tools should be used to keep serum phosphate levels below 2 mmol/L. To prevent vascular dementia, lifestyle modification should be undertaken, including optimal physical activity and fat intake, nicotine abstinence, and targeting optimal blood glucose, cholesterol

    Abstract Background: Trial design neuroinflammation and postoperative pain after surgery are increasingly reported in association with postoperative cognitive dysfunction (POCD). Parecoxib, a selective cyclooxygenase (COX)-2 inhibitor, is used for postoperative analgesia for its potent anti-inflammatory and analgesic effects. This study aimed to evaluate parecoxib's effects on POCD in elderly patients undergoing total knee arthroplasty. Methods: Around 134 elderly patients undergoing total knee arthroplasty were randomly divided into parecoxib (group P) and control (group C) groups, and treated with parecoxib sodium and saline, respectively, shortly after induction of general anesthesia and 12-h postsurgery, respectively. Perioperative plasma IL-1β, IL-6, TNF-α, and C-reactive protein (CRP) 1evels were measured. Postoperative pain was assessed following surgery. Neuropsychological tests were performed before surgery, and 1 week and 3 months postoperation. Results: POCD incidence in group P was significantly lower compared with that of group C at 1 week after surgery (16.7% vs 33.9%; P < 0.05); no significant difference was found between groups C and P at 3-month follow-up (9.7% vs 6.7%). Compared with group C values, visual analog pain scale (VAS) scores at 3, 6, and 12 hours after surgery were significantly lower in group P(P < 0.05). Plasma IL-1β, IL-6, and TNF-α levels were lower in group P than in group C after the operation (P < 0.05). No significant difference in the plasma CRP level was found between groups P and C. Conclusions: Parecoxib sodium decreases POCD incidence after total knee arthroplasty in elderly patients and may explain how this drug suppresses inflammation and acute postoperative pain caused by surgical trauma.

    Long-term clinical and functional outcomes for patients undergoing foot and ankle amputations are not well documented. We attempted to document long-term outcomes for patients who required lower extremity amputations as a result of wounds suffered during wartime. For this study, 27 Iranian soldiers who had wounds requiring amputation of the foot and ankle were selected for follow-up. The participants' wartime medical records were reviewed, a clinical examination was performed, and each participant completed a questionnaire. Postamputation follow-up averaged 17.5 years. The most prevalent (66.6%) cause of injury was a land mine. The prevalences of different clinical symptoms reported by the amputees at the time of the last follow-up were as follows: 11 (40.7%) with phantom sensation, 6 (22.2%) with phantom pain, 12 (44.4%) with stump pain, 12 (44.4%) with back pain, 9 (33.3%) with contralateral knee pain, and 4 (14.8%) with ipsilateral knee pain; 20 (74%) reported treatment for psychological conditions. In regard to social conditions, 13 (48.1) were currently employed, or had been employed, for a number of years after the amputation; 26 (96%) had children, and all of the patients were married. The results of this observational study indicate that individuals have significant long-term pain and discomfort after war-related lower extremity amputation. Although all 27 (100%) of the amputees were able to maintain satisfactory family functioning, only 13 (48.1%) of the study participants were able to remain productively employed after undergoing amputation, and 20 (74%) reported long-term psychological problems in addition to their physical pain.

  16. Estimating Radiation Dose Metrics for Patients Undergoing Tube Current Modulation CT Scans

    McMillan, Kyle Lorin

    Computed tomography (CT) has long been a powerful tool in the diagnosis of disease, identification of tumors and guidance of interventional procedures. With CT examinations comes the concern of radiation exposure and the associated risks. In order to properly understand those risks on a patient-specific level, organ dose must be quantified for each CT scan. Some of the most widely used organ dose estimates are derived from fixed tube current (FTC) scans of a standard sized idealized patient model. However, in current clinical practice, patient size varies from neonates weighing just a few kg to morbidly obese patients weighing over 200 kg, and nearly all CT exams are performed with tube current modulation (TCM), a scanning technique that adjusts scanner output according to changes in patient attenuation. Methods to account for TCM in CT organ dose estimates have been previously demonstrated, but these methods are limited in scope and/or restricted to idealized TCM profiles that are not based on physical observations and not scanner specific (e.g. don't account for tube limits, scanner-specific effects, etc.). The goal of this work was to develop methods to estimate organ doses to patients undergoing CT scans that take into account both the patient size as well as the effects of TCM. This work started with the development and validation of methods to estimate scanner-specific TCM schemes for any voxelized patient model. An approach was developed to generate estimated TCM schemes that match actual TCM schemes that would have been acquired on the scanner for any patient model. Using this approach, TCM schemes were then generated for a variety of body CT protocols for a set of reference voxelized phantoms for which TCM information does not currently exist. These are whole body patient models representing a variety of sizes, ages and genders that have all radiosensitive organs identified. TCM schemes for these models facilitated Monte Carlo-based estimates of fully

    Cesarean section is associated with significant postoperative pain. The aim of this study was to evaluate the effects of tramadol versus bupivacaine administration at wound closure on postoperative pain relief in patients undergoing cesarean section. Sixty women undergoing cesarean deliveries were randomly assigned to receive either 10 mL of bupivacaine 0.5% (n = 30) or 50 mg of tramadol in 10 mL of normal saline (n = 30), both as local wound infiltration prior to skin closure at the end of operation. Postoperative pain was evaluated with a visual analogue scale (VAS: 0-10) at 1, 2 and 6 hours after operation. Time to first analgesic administration and analgesic consumption in 24 hours after operation were recorded and compared between the two groups. Data were analyzed by SPSS software version 15 and p < 0.05 was considered significant. The VAS score did not differ significantly between the two groups at 1 and 2 hours after cesarean section, but it was higher in bupivacaine group than tramadol group 6 hours after operation (p < 0.05; Fisher exact test). Postoperative consumption of analgesic was higher in bupivacaine group than tramadol group but the difference was not significant (p > 0.05; Fisher exact test). No side effects were reported in either group. This study showed that subcutaneous administration of tramadol provided analgesic effect equal to bupivacaine with longer pain relief after cesarean section.

METHOD: a transversal study, undertaken using a questionnaire. The sample was made up of 178 individuals. The Chi-squared and Mann-Whitney U tests were undertaken. RESULTS: the adaptation problems and the socioeconomic and clinical aspects which presented statistical associations were: Hyperkalemia and age; Edema and income; Impairment of a primary sense: touch and income; Role failure and age; Sexual dysfunction and marital status and sex; Impairment of a primary sense: vision and years of education; Intolerance to activity and years of education; Chronic pain and sex and years of education; Impaired skin integrity and age: Hypocalcemia and access; Potential for injury and age and years of education; Nutrition below the organism's requirements and age; Impairment of a primary sense: hearing and sex and kinetic evaluation of urea; Mobility in gait and/or coordination restricted, and months of hemodialysis; and, Loss of ability for self-care, and months of hemodialysis and months of illness. CONCLUSION: adaptation problems in the clientele undergoing hemodialysis can be influenced by socioeconomic/clinical data. These findings contribute to the development of the profession, fostering the nurse's reflection regarding the care. PMID:25591091

    Pulmonary arterial hypertension is a common and fatal complication of scleroderma that may involve inflammatory and autoimmune mechanisms. Alterations in the gene expression of peripheral blood mononuclear cells have been previously described in patients with pulmonary arterial hypertension. Our goal is to identify differentially expressed genes in peripheral blood mononuclear cells in scleroderma patients with and without pulmonary hypertension as biomarkers of disease. Gene expression analysis was performed on a Microarray Cohort of scleroderma patients with (n=10) and without (n=10) pulmonary hypertension. Differentially expressed genes were confirmed in the Microarray Cohort and validated in a Validation Cohort of scleroderma patients with (n=15) and without (n=19) pulmonary hypertension by RT-qPCR. We identified inflammatory and immune-related genes including interleukin-7 receptor (IL-7R) and chemokine receptor 7 as differentially expressed in patients with scleroderma-associated pulmonary hypertension. Flow cytometry confirmed decreased expression of IL-7R on circulating CD4+ T-cells from scleroderma patients with pulmonary hypertension. Differences exist in the expression of inflammatory and immune-related genes in peripheral blood cells from patients with scleroderma-related pulmonary hypertension compared to those with normal pulmonary artery pressures. These findings may have implications as biomarkers to screen at-risk populations for early diagnosis and provide insight into mechanisms of scleroderma-related pulmonary hypertension. PMID:20973920

    Background and Purpose. Regulatory T cells (Tregs) have been suggested to modulate stroke-induced immune responses. However, analyses of Tregs in patients and in experimental stroke have yielded contradictory findings. We performed the current study to assess the regulation and function of Tregs in peripheral blood of stroke patients. Age dependent expression of CD39 on Tregs was quantified in mice and men. Methods. Total FoxP3+ Tregs and CD39+FoxP3+ Tregs were quantified by flow cytometry in controls and stroke patients on admission and on days 1, 3, 5, and 7 thereafter. Treg function was assessed by quantifying the inhibition of activation-induced expression of CD69 and CD154 on T effector cells (Teffs). Results. Total Tregs accounted for 5.0% of CD4+ T cells in controls and <2.8% in stroke patients on admission. They remained below control values until day 7. CD39+ Tregs were most strongly reduced in stroke patients. On day 3 the Treg-mediated inhibition of CD154 upregulation on CD4+ Teff was impaired in stroke patients. CD39 expression on Treg increased with age in peripheral blood of mice and men. Conclusion. We demonstrate a loss of active FoxP3+CD39+ Tregs from stroke patient's peripheral blood. The suppressive Treg function of remaining Tregs is impaired after stroke. PMID:27073295

    Background The association of congenital heart disease (CHD) with malformations of the gastrointestinal (GI) tract/abdominal wall is known. The rates of cardiac malformations reported in previous studies of these anomalies are highly variable. Objective To find the prevalence and pattern of CHD in patients with major gastrointestinal malformations (anorectal malformations, oesophageal atresia/tracheo-oesophageal fistula, and omphalocoele) undergoing surgery at a tertiary care hospital in India. Methods From July 2012 to December 2013, 43 patients (34 (79%) male, 9 (21%) female) were evaluated by clinical examination, ECG, chest radiography, and colour Doppler echocardiography. Results Of the 43 patients, 26 (60.46%) had CHD. The most common GI malformation was anorectal malformation: 32 cases (74.41%), of whom 16 (50%) had CHD. The second most common malformation was oesophageal atresia/tracheo-oesophageal fistula: 5 cases (11.62%), all (100%) with CHD. The third group comprised patients with omphalocoele: 4 cases (9.3%), 3 of whom (75%) had CHD. The fourth group comprised patients with VACTERAL (vertebral anomalies, anal atresia, cardiovascular malformations, tracheo-oesophageal fistula, renal and limb anomalies) association—2 cases (4.6%), all (100%) with CHD. The most common CHD was isolated atrial septal defect (ASD) (73%), followed by ASD + ventricular septal defect (VSD) + patent ductus arteriosus (PDA) (7.6%), ASD + VSD (3.8%), ASD + PDA (3.8%), VSD (3.8%), PDA (3.8%), and coarctation of the aorta (3.8%). Conclusions We found the frequency of CHD in patients with GI malformations was very high, the most common presentation being ASD. Our study indicates the need for larger scale studies to determine the prevalence of CHD in patients with GI malformations in the Indian population. PMID:27326210

    Purpose The goal of this study was to characterize changes in daily fatigue in women undergoing chemotherapy for breast cancer. We examined whether there are subgroups of patients with distinct fatigue trajectories and explored potential psychosocial and biomedical predictors of these subgroups. Methods Participants were 77 women with breast cancer receiving adjuvant chemotherapy with AC-T (2-week cycle) and TC or TCH (3-week cycle) regimens. They completed 28 daily ratings online using an adapted version of the Patient-Reported Outcomes Measurement Information System (PROMIS®) fatigue instrument. Results Both regimens followed an “inverted-U shaped” fatigue pattern over approximately 2 weeks. Growth mixture modeling identified three patient subgroups with distinct trajectories. Fatigue scores in the “low fatigue” group (23%) increased following the infusion and quickly abated. The “transient fatigue” (27%) group had a very pronounced increase. Patients in the “high fatigue” (50%) group reported consistently elevated fatigue with a relatively small increase. Demographic and medical variables were not associated with fatigue trajectory. Patients in the “high fatigue” group reported significantly poorer physical, emotional, and social functioning, poorer general health, and more depressed mood than patients in the “low fatigue” group. The “transient fatigue” group reported significantly better physical and social functioning than the “high fatigue” group, but emotional distress and depression similar to the “high fatigue” group. Conclusions The identification of patient subgroups with distinct fatigue trajectories during chemotherapy is an essential step for developing preventative strategies and tailored interventions. Our results suggest that different trajectories are associated with patients’ psychosocial and general health. PMID:25876159

    Micturating cystourethrography (MCU) is considered to be the gold-standard method used to detect and grade vesicoureteric reflux (VUR) and show urethral and bladder abnormalities. It accounts for 30-50% of all fluoroscopic examinations in children. Therefore, it is crucial to define and optimize the radiation dose received by a child during MCU examination, taking into account that children have a higher risk of developing radiation-induced cancer than adults. This study aims to quantify and evaluate, by means of thermoluminescence dosimetry (TLD), the radiation dose to the newborn and paediatric populations undergoing MCU using fluoroscopic imaging. Evaluation of entrance surface dose (ESD), organ and surface dose to specific radiosensitive organs was carried out. Furthermore, the surface dose to the co-patient, i.e. individuals helping in the support, care and comfort of the children during the examination, was evaluated in order to estimate the level of risk. 52 patients with mean age of 0.36 years who had undergone MCU using digital fluoroscopy were studied. ESD, surface doses to thyroid, testes/ovaries and co-patients were measured with TLDs. MCU with digital equipment and fluoroscopy-captured image technique can reduce the radiation dose by approximately 50% while still obtaining the necessary diagnostic information. Radiographic exposures were made in cases of the presence of reflux or of the difficulty in evaluating a finding. The radiation surface doses to the thyroid and testes are relatively low, whereas the radiation dose to the co-patient is negligible. The risks associated with MCU for patients and co-patients are negligible. The results of this study provide baseline data to establish reference dose levels for MCU examination in very young patients.

    Purpose: Approximately 5% to 20% of patients who undergo total body irradiation (TBI) in preparation for hematopoietic cell transplantation (HCT) can develop extramedullary (EM) relapse. Whereas total marrow and lymphoid irradiation (TMLI) provides a more conformally targeted radiation therapy for patients, organ sparing has the potential to place the patient at a higher risk for EM relapse than TBI. This study evaluated EM relapse in patients treated with TMLI at our institution. Methods and Materials: Patients eligible for analysis had been enrolled in 1 of 3 prospective TMLI trials between 2006 and 2012. The TMLI targeted bones, major lymph node chains, liver, spleen, testes, and brain, using image-guided tomotherapy with total dose ranging from 12 to 15 Gy. Results: A total of 101 patients with a median age of 47 years were studied. The median follow-up was 12.8 months. Incidence of EM relapse and bone marrow (BM) relapse were 12.9% and 25.7%, respectively. Of the 13 patients who had EM relapse, 4 also had BM relapse, and 7 had EM disease prior to HCT. There were a total of 19 EM relapse sites as the site of initial recurrence: 11 soft tissue, 6 lymph node, 2 skin. Nine of these sites were within the target region and received ≥12 Gy. Ten initial EM relapse sites were outside of the target region: 5 sites received 10.1 to 11.4 Gy while 5 sites received <10 Gy. Pretransplantation EM was the only significant predictor of subsequent EM relapse. The cumulative incidence of EM relapse was 4% at 1 year and 11.4% at 2 years. Conclusions: EM relapse incidence was as frequent in regions receiving ≥10 Gy as those receiving <10 Gy. EM relapse rates following TMLI that included HCT regimens were comparable to published results with regimens including TBI and suggest that TMLI is not associated with an increased EM relapse risk.

    Objective to analyze the relationship between the hope and spirituality of patients with chronic kidney disease undergoing hemodialysis. Method this is a cross-sectional, correlational study. The sample was composed of 127 patients of a Renal Replacement Unit. Data were collected through individual interviews guided by the following instruments: participant characterization, Herth Hope Index (HHI), and Pinto Pais-Ribeiro Spirituality Scale (PP-RSS). Results the average HHI score was 38.06 (±4.32) while the average PP-RSS score was 3.67 (±0.62) for "beliefs" and 3.21 (±0.53) for "hope/optimism". Spearman's coefficient indicated there was a moderate positive correlation between the HHI and PP-RSS dimensions of "beliefs" (r=0.430; p<0.001) and "hope/optimism" (r=0.376; p<0.001). Conclusion Since a relationship between the sense of hope and spirituality of patients with chronic kidney disease was found, these constructs should be taken into account at the time health professionals deliver care to help patients coping with the disease and treatment.

    This study aimed to determine clinical features of adult patients with gelastic seizures recorded on video -electroencephalography (EEG) over a 5-year period. We screened video-EEG telemetry reports for the occurrence of the term "gelastic" seizures, and assessed the semiology, EEG features, and duration of those seizures. Gelastic seizures were identified in 19 (0.8%) of 2,446 admissions. The presumed epileptogenic zone was in the hypothalamus in one third of the cases, temporal lobe epilepsy was diagnosed in another third, and the remainder of the cases presenting with gelastic seizures were classified as frontal, parietal lobe epilepsy or remained undetermined or were multifocal. Gelastic seizures were embedded in a semiology, with part of the seizure showing features of automotor seizures. A small proportion of patients underwent epilepsy surgery. Outcome of epilepsy surgery was related to the underlying pathology; two patients with hippocampal sclerosis had good outcomes following temporal lobe resection and one of four patients with hypothalamic hamartomas undergoing gamma knife surgery had a good outcome.

    We report a systematic review and meta-analysis of the peer-reviewed literature focusing on metal sensitivity testing in patients undergoing total joint replacement (TJR). Our purpose was to assess the risk of developing metal hypersensitivity post-operatively and its relationship with outcome and to investigate the advantages of performing hypersensitivity testing. We undertook a comprehensive search of the citations quoted in PubMed and EMBASE: 22 articles (comprising 3634 patients) met the inclusion criteria. The frequency of positive tests increased after TJR, especially in patients with implant failure or a metal-on-metal coupling. The probability of developing a metal allergy was higher post-operatively (odds ratio (OR) 1.52 (95% confidence interval (CI) 1.06 to 2.31)), and the risk was further increased when failed implants were compared with stable TJRs (OR 2.76 (95% CI 1.14 to 6.70)). Hypersensitivity testing was not able to discriminate between stable and failed TJRs, as its predictive value was not statistically proven. However, it is generally thought that hypersensitivity testing should be performed in patients with a history of metal allergy and in failed TJRs, especially with metal-on-metal implants and when the cause of the loosening is doubtful.

    Background Bariatric surgery is considered the only effective method to treat refractory obesity, and especially for those in which clinical treatment was not successful. However, the appearance of food intolerances and clinical manifestations are quite common. Aim To identify food intolerances and associated them to symptoms in patients undergoing Fobi-Capella technique without gastric ring. Methods This was a cross-sectional study of adult patients who had more than one year after surgery. Demographic, anthropometric, weight and preoperative height data were investigated. Nutritional status was classified according to the criteria established by the World Health Organization. It was considered food intolerance the presence of nausea, vomiting, diarrhea or bloating after eating a particular food. Results The sample consisted of 61 patients who attended the nutritional consultation of which 26 (42.6%) had food intolerance, mostly related to red meat (n=12; 34.3%) during the first six months of operation; there was a significant difference between the periods between 0 and 6 months, and 7 to 12 (p=0.02). Among the symptoms reported by patients, nausea was the most recurrent until the 6th month, but without significant differences between the two periods (p=0.06). Conclusions The Fobi-Capella procedure without gastric ring promoted high frequency of intolerance to meat in general, especially for the red, chicken and fish, on this sequence; nausea was the most frequent symptom. These data suggest the need for adequate nutritional monitoring throughout the postoperative period. PMID:25861067

    Background To assess the utilization of stress management in relieving anxiety and pain among patients who undergo transrectal ultrasound (TRUS)-guided biopsy of the prostate. Methods Eighty-two patients admitted to a community hospital for a TRUS biopsy of the prostate participated in this case-controlled study. They were divided into an experimental group that was provided with stress management and a control group that received only routine nursing care. Stress management included music therapy and one-on-one simulation education. Before and after the TRUS biopsy, the patients’ state-anxiety inventory score, pain visual analogue scale (VAS), respiratory rate, heart rate, and blood pressure were obtained. Results There were no differences in baseline and disease characteristics between the two groups. The VAS in both groups increased after the TRUS biopsy, but the difference in pre- and postbiopsy VAS scores was significantly lower in the experimental group (P=0.03). Patients in both groups experienced mild anxiety before and after the biopsy, but those in the experimental group displayed a significantly greater decrease in postbiopsy state-anxiety inventory score compared to the control group (P=0.02). Conclusion Stress management can alleviate anxiety and pain in patients who received a TRUS biopsy of the prostate under local anesthesia. PMID:26929606

    Objectives: To investigate whether mitral valve repair (MVR) at the time of coronary artery bypass grafting (CABG) in patients with ischemic moderate mitral regurgitation (MR) and coronary artery disease could improve short- and mid-term postoperative outcomes. Methods: Between March 2013 and December 2015, 90 patients with moderate ischemic MR underwent first-time CABG in Bursa Yuksek Ihtisas Training and Research Hospital, Bursa, Turkey. Out of 90 patients, 44 (48.9%) underwent combined CABG+MVR. The remaining 46 (51.1%) underwent CABG alone. Ventricular functions and effort capacities of patients in both groups were evaluated echocardiographically and clinically in the preoperative period, and in the first postoperative year. Results: Postoperative regurgitant volume changes according to preoperative values were -24.76±19 ml/beat in the combined CABG+MVR group, and -8.70±7.2 ml/beat in the CABG alone group (p=0.001). The change of vena contracta width was -3.40±0.2 mm in the combined CABG+MVR group whereas in the CABG alone -1.45±0.7 mm (p=0.019). The changes of left ventricular end-systolic volume index were -30.77±25.9 ml/m2 in the combined CABG+MVR group and -15.6±9.4 ml/m2 in the CABG alone group (p=0.096). Ejection fraction changes in the combined CABG+MVR group was +1.51±5.3% and in the CABG alone group was +1.15±4.3%. No statistically significant difference was found between both groups (p=0.604). Preoperative New York Heart Association class values in the combined CABG+MVR group was 2.18±0.45, and in the CABG alone group was 2.13±0.54. Conclusions: Moderate MR in patients undergoing CABG affects the outcome adversely and it does not reliably improve after CABG alone. Therefore, patients with ischemic moderate MR should undergo simultaneous MVR at the time of CABG. PMID:27464861

    The purpose of this study was to evaluate the effect of z overscanning on normalized effective dose for pediatric patients undergoing multidetector-computed tomography (CT) examinations. Five commercially available mathematical anthropomorphic phantoms representing newborn, 1-, 5-, 10-, and 15-year-old patients and the Monte Carlo N-Particle (MCNP, version 4C2) radiation transport code were employed in the current study to simulate pediatric CT exposures. For all phantoms, axial and helical examinations at 120 kV tube voltage were simulated. Scans performed at 80 kV were also simulated. Sex-specific normalized effective doses were estimated for four standard CT examinations i.e., head-neck, chest, abdomen-pelvis, and trunk, for all pediatric phantoms. Data for both axial and helical mode acquisition were obtained. In the helical mode, z overscanning was taken into account. The validity of the Monte Carlo results was verified by comparison with dose data obtained using thermoluminescence dosimetry and a physical pediatric anthropomorphic phantom simulating a 10-year-old child. In all cases normalized effective dose values were found to increase with increasing z overscanning. The percentage differences in normalized data between axial and helical scans may reach 43%, 70%, 36%, and 26% for head-neck, chest, abdomen-pelvis, and trunk studies, respectively. Normalized data for female pediatric patients was in general higher compared to male patients for all ages, examined regions, and z overscanning values. For both male and female children, the normalized effective dose values were reduced as the age was increased. For the same typical exposure conditions, dose values decreased when lower tube voltage was used; for a 1-year-old child, for example, the effective dose was 3.8 times lower when 80 kV instead of 120 kV was used. Normalized data for the estimation of effective dose to pediatric patients undergoing standard axial and helical CT examinations on an

    Background Cardiotoxicity from anthracycline-based chemotherapy is an important cause of early and late morbidity and mortality in breast cancer patients. Left ventricular (LV) function is assessed for patients receiving anthracycline-based chemotherapy to identify cardiotoxicity. However, animal studies suggest that right ventricular (RV) function may be a more sensitive measure to detect LV dysfunction. The purpose of this pilot study was to determine if breast cancer patients undergoing anthracycline-based chemotherapy experience RV dysfunction. Methods Forty-nine breast cancer patients undergoing anthracycline-based chemotherapy at the Ottawa Hospital between November 2007 and March 2013 and who had 2 echocardiograms performed at least 3months apart were retrospectively identified. Right atrial area (RAA), right ventricular fractional area change (RV FAC) and RV longitudinal strain of the free wall (RV LSFW) were evaluated according to the American Society of Echocardiography guidelines. Results The majority (48/49) of patients were females with an average age of 53.4 (95% CI: 50.1–56.7years). From baseline to follow-up study, average LV ejection fraction (LVEF) decreased from 62.22 (95% CI: 59.1–65.4) to 57.4% (95% CI: 54.0–60.9) (P=0.04). During the same time period, the mean RAA increased from 12.1cm2 (95% CI: 11.1–13.0cm2) to 13.8cm2 (95% CI: 12.7–14.9cm2) (P=0.02), mean RV FAC decreased (P=0.01) from 48.3% (95% CI: 44.8–51.74) to 42.1% (95% CI: 38.5–45.6%), and mean RV LSFW worsened from −16.2% (95% CI: −18.1 to −14.4%) to −13.81% (95% CI: −15.1 to −12.5%) (P=0.04). Conclusion This study demonstrates that breast cancer patients receiving anthracycline-based chemotherapy experience adverse effects on both right atrial size and RV function. Further studies are required to determine the impact of these adverse effects on right heart function and whether this represents an earlier marker of cardiotoxicity. PMID:27457966

    As of 2000, more adults than children are alive with congenital heart disease. Each year, more of these adults with congenital heart disease undergo surgery. Adults with congenital heart disease require lifelong surveillance, follow-up imaging, and clinical decision making by appropriately trained and familiar physicians and extenders. Three common challenges facing adults with congenital heart disease are the neglected patient, weak programmatic infrastructure, and the planning and management of pregnancy in the adult with congenital heart disease. Many challenges must be overcome in order to establish and maintain a comprehensive medical and surgical program for adults with congenital heart disease. Three common and challenging groups of adults with congenital heart disease who may require surgery are adults requiring tricuspid valve surgery for Ebstein's malformation, those requiring reoperation for failing Fontan circulation, and those requiring pulmonary valve replacement (PVR). Surgery for Ebstein's anomaly is now offered to older patients at low risk and with good late outcome. The operation includes tricuspid valve repair or replacement and frequent concomitant procedures such as atrial septal defect closure, arrhythmia surgery (the Maze procedure), and coronary artery bypass grafting. Patients undergoing previous iterations of the Fontan operation are especially prone to arrhythmia and failing circulation. Fontan conversion with arrhythmia surgery and pacemaker therapy was developed by Constantine Mavroudis, Barbara Deal, and Carl Backer to treat these challenging patients, with the first such operation performed in 1994. Fontan conversion involves: (1) conversion of the previously created atriopulmonary connection to a total cavopulmonary connection (TCPC), extracardiac Fontan; (2) arrhythmia surgery, typically with a modified biatrial Maze procedure along with placement of an antitachycardia, dual-chamber pacemaker with steroid-eluting epicardial leads

    Disorders of iron utilization caused by abnormal elevation of hepcidin levels are the main mechanism of anemia of chronic disease. Hepcidin is mainly produced by the liver. Recently it has been found that monocytes are another source of hepcidin. The increased hepcidin in serum and urine of multiple myeloma patients may be one cause of anemia of chronic disease (ACD). However it is unclear whether the peripheral blood monocyte hepcidin is involved in the pathogenesis of anemia of chronic disease. This study was purposed to investigate the role of monocyte hepcidin in multiple myeloma patients with anemia of chronic disease. The clinical data and peripheral venous blood of multiple myeloma patients were collected.Serum concentration of IL-6 and TNF-α was detected by ELISA. Peripheral blood monocytes were isolated by CD14(+) magnetic beads. Hepcidin, IL-6 and TNF-α mRNA of monocytes were detected by real time quantitative PCR. The results showed that the expression level of monocyte hepcidin mRNA in myeloma patients was higher than that in normal controls. In untreated patients, the expression level of monocyte hepcidin mRNA was negatively correlated with hemoglobin, and positively correlated with serum ferritin and IL-6 levels, but unrelated with TNF-α levels.It is concluded that the increased monocyte hepcidin levels in multiple myeloma patients may play an etiologic role in ACD.

    One of the reasons for the increased susceptibility to infections in patients with Alzheimer disease may be enhanced apoptotic death of their peripheral leukocytes. If this is the case, the enhanced apoptosis may be due to components in the patients' sera or to an increased sensitivity of the cells to apoptotic stimuli. To examine this possibility, the percentage of apoptotic cells in the peripheral blood mononuclear cells (PBMC) from 12 patients with Alzheimer disease was compared with that of 12 age-matched non-demented persons and 12 middle-aged healthy control subjects. In addition, the effect of sera from subjects in the three groups on the apoptosis, interleukin (IL)-1beta, IL-2, IL-6, IL-10, and tumor necrosis factor (TNF)alpha production by peripheral blood cells from healthy control subjects was examined. It was found that the percentage of apoptotic PBMC from patients with Alzheimer disease was higher than that from the remaining two groups. However, incubation of control cells with sera from patients with Alzheimer disease and non-demented elderly persons did not affect the number of apoptotic cells. Sera from patients with Alzheimer disease and non-demented elderly subjects caused an increase in IL-2 and a decrease in IL-10 production by PBMC from middle-aged control subjects but did not affect IL-1beta, IL-6, and TNFalpha secretion, indicating alterations of the immune system related to aging.

    Objective To assess the prevalence and risk factors of erectile dysfunction (ED) in HIV patients from the HIV clinic of a tertiary referral center in Mexico City. Design Prevalence was obtained from cross-sectional studies, and the International Index of Erectile Function (IIEF), a standardized method, was used to assess ED. Methods A cross-sectional study was performed in the HIV clinic. Participants completed the IIEF to allow ED assessment. Information on demographics, clinical and HIV-related variables was retrieved from their medical records. Results One hundred and nine patients were included, with a mean age of 39.9 ± 8.8 years. ED was present in 65.1% of the individuals. Patients had been diagnosed with HIV for a mean of 92.7 ± 70.3 months and had undergone a mean 56.4 ± 45.5 months of HAART. The only variable associated with ED in the univariate analysis was dyslipidemia, and this association was also found in the multivariate analysis (P = 0.01). Conclusions ED is highly prevalent in HIV patients. Dyslipidemia should be considered as a risk factor for ED in HIV patients.

    Background and Purpose Enrollment in the SAMMPRIS trial was halted due to the high risk of stroke or death within 30 days of enrollment in the percutaneous transluminal angioplasty and stenting (PTAS) arm relative to the medical arm. This analysis focuses on the patient and procedural factors that may have been associated with peri-procedural cerebrovascular events in the trial. Methods Bivariate and multivariate analyses were performed to evaluate whether patient and procedural variables were associated with cerebral ischemic or hemorrhagic events occurring within 30 days of enrollment (termed peri-procedural) in the PTAS arm. Results Of 224 patients randomized to PTAS, 213 underwent angioplasty alone (n=5) or with stenting (n=208). Of these, 13 had hemorrhagic strokes (7 parenchymal, 6 subarachnoid), 19 had ischemic stroke, and 2 had cerebral infarcts with temporary signs (CITS) within the peri-procedural period. Ischemic events were categorized as perforator occlusions (13), embolic (4), mixed perforator and embolic (2), and delayed stent occlusion (2). Multivariate analyses showed that higher percent stenosis, lower modified Rankin score, and clopidogrel load associated with an activated clotting time above the target range were associated (p ≤ 0.05) with hemorrhagic stroke. Non-smoking, basilar artery stenosis, diabetes, and older age were associated (p ≤ 0.05) with ischemic events. Conclusions Peri-procedural strokes in SAMMPRIS had multiple causes with the most common being perforator occlusion. Although risk factors for peri-procedural strokes could be identified, excluding patients with these features from undergoing PTAS to lower the procedural risk would limit PTAS to a small subset of patients. Moreover, given the small number of events, the present data should be used for hypothesis generation rather than to guide patient selection in clinical practice. PMID:22984008

    Purpose: To study the prognostic value of the human papillomavirus (HPV) genotypes in cervical cancer patients undergoing radiotherapy. Patients and Methods: A total of 1,010 patients with cervical cancer after radiotherapy between 1993 and 2000 were eligible for this study. The HPV genotypes were determined by a genechip, which detects 38 types of HPV. The patient characteristics and treatment outcomes were analyzed using the Cox regression hazard model and classification and regression tree decision tree method. Results: A total of 25 genotypes of HPV were detected in 992 specimens (98.2%). The leading 8 types were HPV16, 58, 18, 33, 52, 39, 31, and 45. These types belong to two high-risk HPV species: alpha-7 (HPV18, 39, 45) and alpha-9 (HPV16, 31, 33, 52, 58). Three HPV-based risk groups, which were independent of established prognostic factors, such as International Federation of Gynecology and Obstetrics stage, age, pathologic features, squamous cell carcinoma antigen, and lymph node metastasis, were associated with the survival outcomes. The high-risk group consisted of the patients without HPV infection or the ones infected with the alpha-7 species only. Patients co-infected with the alpha-7 and alpha-9 species belonged to the medium-risk group, and the others were included in the low-risk group. Conclusion: The results of the present study have confirmed the prognostic value of HPV genotypes in cervical cancer treated with radiotherapy. The different effect of the alpha-7 and alpha-9 species on the radiation response deserves additional exploration.

    Clostridium difficile infections (CDI) remain the leading cause of infectious diarrhea among hospitalized patients in this country. Patients with hematologic malignancies, especially those who undergo hematopoietic progenitor cell transplants are particularly at risk for developing CDI. One hundred and forty seven consecutive allogeneic hematopoietic progenitor cell transplants were analyzed for peri-transplant Clostridium difficile infections (PT-CDI). Sixteen patients (11%) developed PT-CDI (Median time = 7 days after transplant). The probability for developing PT-CDI during the peri-transplant period was 12.3%. History of CDI was strongly associated with the development of PT-CDI (P = 0.008) (OR = 5.48) (P = 0.017). These patients also developed PT-CDI much earlier than in those without a history (median 1 day vs. 8 days, P = 0.03). The probability for developing PT-CDI for those with a history was 39%. There was a trend toward significance (P = 0.065) between matched related donor grafts and the development of PT-CDI (OR = 0.245) (P = 0.08). Age, sex, diagnosis, transplant preparative regimens, Graft-versus-host disease (GVHD) prophylaxis, grade 3/4 acute GVHD, or use of antimicrobials within 8 weeks of transplant were not associated with PT-CDI. Non-CDI-related deaths occurred in one patient in the PT-CDI group and nine in the group without PT-CDI. In the remaining 139 patients, the length of hospital stay for those with PT-CDI was significantly longer than those without (mean 27 days vs. 22 days; P = 0.02). PMID:26661725

    The goal of this study was to explore the polymorphisms of CYP2C19 (CYP2C19*2, CYP2C19*3) in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) on clopidogrel therapy in Zhengzhou city for guidance on clinical medication and reduction in the incidence of thromboembolic events. Two hundred and thirty-four ACS patients undergoing PCI were included in the study, including 171 males (average age = 64.13 ± 12 years) and 63 females (average age = 67.86 ± 10.20 years). Pyrosequencing analysis detected CYP2C19*2/*3 genotypes, which were divided into wild-type homozygous C/C, mutant heterozygous C/T, and mutant homozygous T/T. This study further explored the relationship between CYP2C19 polymorphisms and clopidogrel resistance in ACS patients. Gene frequencies of C/C, C/T, and T/T for CYP2C19*2 were 39.74, 50, and 10.26%, respectively, while the frequencies of C/C, C/T, and T/T for CYP2C19*3 were 94.02, 5.55, and 0.43%, respectively. According to platelet aggregation analysis, 203 cases normally responded to clopidogrel (86.8%) and 31 cases were clopidogrel resistant (13.2%). There was a correlation between gender and genotype distribution but none between age and genotype. In addition, patients with clopidogrel resistance were treated with ticagrelor antiplatelet therapy instead of clopidogrel, and only 1 case in all patients suffered thrombotic events during a 3-12 month follow-up. In conclusion, CYP2C19*2/*3 polymorphisms may be associated with clopidogrel resistance. Wild-type homozygote and single mutant heterozygote of CYP2C19*2/*3 can be given a normal dose of clopidogrel, while carriers with single mutant homozygote or double mutant heterozygote require ticagrelor antiplatelet therapy as an alternative.

    Objective: To discuss the effect of preemptive analgesia with parecoxib sodium in patients undergoing radical resection of lung cancer. Methods: 115 cases of lung cancer patients with American society of anesthesiologists class (ASA) grade I~II who received selective operation were randomly divided into the research group and the control group. The research group patients were given preoperative parecoxib sodium 40 mg plus postoperative normal saline 2 ml, while the control group patients were treated with preoperative normal saline 2 ml plus postoperative parecoxib sodium 40 mg. The pain condition at postoperative 1, 2, 4, 8, 12, 24 and 48 h were evaluated by visual analogue scale (VAS), and emergence agitation was tested by agitation score. Results: Finally there were 56 cases and 57 cases can be used for evaluation in the research group and control group. The VAS scores after 1, 2, 4, 8, 12, 24 and 48 h in the research group and control group were [2.23±0.45, 2.35±0.48, 2.51±0.51, 2.41±0.45, 2.28±0.42, 2.16±0.39, 2.11±0.40] and [3.80±0.62, 4.01±0.64, 4.31±0.67, 4.10±0.64, 3.65±0.70, 3.12±0.66, 2.46±0.53], respectively. The research group were obviously lower than the control group, the difference were statistically significant (P<0.05). The rate of agitation was 24.44% (11/56) in the research group, significantly lower than the control group of 59.65% (34/57) (P<0.05). Conclusion: Preemptive analgesia with parecoxib sodium can obviously relieve acute pain using in patients undergoing radical resection of lung cancer, and is helpful to reduce the incidence of emergence agitation.

    There is a close relationship between sleep disordered breathing (SDB) and heart failure. We performed home oxygen therapy (HOT) in patients with SAS undergoing dialysis, and investigated its effects on the heart function. The subjects were 10 SDB patients on dialysis. On retiring at night, oxygen was transnasally administered at 1.0 L/min. The human atrial natriuretic peptide (hANP), brain natriuretic peptide (BNP), total protein, Alb, cholesterol and phosphorus levels were measured before the start of oxygen therapy and after 6 weeks. The mean SpO2 increased from 93.5% [91.5, 97.0] to 96.3% [94.8, 97.4] (median [interquartile range]) (p = 0.015). The hANP (p = 0.0039), BNP (p = 0.0098) and serum Alb (p = 0.015) levels significantly improved. There were no significant changes in the cholesterol, phosphorus or total protein levels. These results suggest that nocturnal oxygen therapy improves indices of heart failure, contributing to the prevention and treatment of heart failure in dialysis patients with SDB.

    Radiocontrast-induced nephropathy (RCIN) is an acute and severe complication after coronary angiography, particularly for patients with pre-existing chronic kidney disease (CKD). It has been associated with both short- and long-term adverse outcomes, including the need for renal replacement therapy, increased length of hospital stay, major cardiac adverse events, and mortality. RCIN is generally defined as an increase in serum creatinine concentration of 0.5 mg/dL or 25% above baseline within 48 h after contrast administration. There is no effective therapy once injury has occurred, therefore, prevention is the cornerstone for all patients at risk for acute kidney injury (AKI). There is a small but growing body of evidence that prevention of AKI is associated with a reduction in later adverse outcomes. The optimal strategy for preventing RCIN has not yet been established. This review discusses the principal risk factors for RCIN, evaluates and summarizes the evidence for RCIN prophylaxis, and proposes recommendations for preventing RCIN in CKD patients undergoing coronary angiography.

    In the healthy heart, left ventricular (LV) filling generates flow patterns which have been proposed to optimize blood transport by coupling diastole and systole phases. We present a novel image-based method to assess how flow patterns influence LV blood transport in patients undergoing cardiac resynchronization therapy (CRT). Solving the advection equation with time-varying inflow boundary conditions allows to track the transport of blood entering the LV in the different filling waves, as well as the transport barriers which couple filling and ejection. The velocity fields were obtained using echocardiographic color Doppler velocimetry, which provides two-dimensional time-resolved flow maps in the apical long axis three-chamber view of the LV. We analyze flow transport in a group of patients with CRT devices as well as in healthy volunteers. In the patients under CRT, the device programming was varied to analyze flow transport under different values of the atrioventricular (AV) conduction delay and to model tachycardia. This analysis illustrates how CRT influences the transit of blood inside the LV, contributes to conserving kinetic energy and favors the generation of hemodynamic forces that accelerate blood in the direction of the LV outflow tract.

    Background. The sensitivity and the specificity of different methods to detect periprosthetic infection have been questioned. The current study aimed to investigate the kinetics of C-reactive protein (CRP) and procalcitonin (PCT) in patients undergoing uncomplicated elective total hip arthroplasty (THA), to provide a better interpretation of their levels in noninfectious inflammatory reaction. Methods. A total of 51 patients were included. Serum CRP and PCT concentrations were obtained before surgery, on the 1st, 3rd, and 7th postoperative days and after discharge on the 14th and 30th days and at 2 years. Results. Both markers were confirmed to increase after surgery. The serum CRP showed a marked increase on the 3rd postoperative day while the peak of serum PCT was earlier, even if much lower, on the first day. Then, they declined slowly approaching the baseline values by the second postoperative week. PCT mean values never exceed concentrations typically related to bacterial infections. Conclusions. CRP is very sensitive to inflammation. It could be the routine screening test in the follow-up of THA orthopaedic patients, but it should be complemented by PCT when there is the clinical suspicion of periprosthetic infection.

    Background: Uncuffed endotracheal tubes are commonly used in children but due to several decade preferred in paediatric oral surgery. Due to lack of conclusive evidences in this regard, we have conducted this study to compare post-operative morbidity following use of cuffed and uncuffed endotracheal tubes in paediatric patients undergoing cleft lip-palate surgery. Methods: This randomised controlled trial was conducted on children aged 2 to 12 years.110 patients were allocated in two parallel groups using computer generated list of random numbers. Post operative extubation stridor, sore throat, time to first oral intake and regaining of normal voice were compared between two groups. Results: The incidence of sore throat was significantly more (P value > 0.005) in patients of uncuffed group compared to cuffed group. The time to first oral intake and time to regain normal voice were significantly earlier in cuffed group compared to the other. Conclusion: With standard care, preformed cuffed ET tube has shown reduced incidence of post operative sore throat. Cuffed group has earlier oral intake and normal voice regain compared to uncuffed group. PMID:27051374

    Aims We sought to explore the response of the corrected QT (QTc) interval duration and QT dispersion (QTD) to hemodialysis. Methods We enrolled 50 patients with end-stage renal disease undergoing regular hemodialysis. Blood samples were drawn for measurement of serum electrolytes, and a 12-lead ECG was performed to measure the QTc interval duration and QTD, immediately before and just after dialysis sessions. Results The mean age of the cohort was 42.8 ± 12.2 years (58% males). Both the QTc duration and QTD showed marked variability after hemodialysis. A significant correlation was found between the decrease of both serum potassium and magnesium levels after dialysis and the post-dialysis QTc interval duration, with Pearson's correlation coefficients r = −0.43 and r = −0.34, p = 0.002 and p = 0.01, respectively. Patients with a post-dialysis increase of QTc interval duration had a significantly higher percentage of reduction of serum potassium (p = 0.029), whereas patients with a post-dialysis increase of QTD had a significantly higher percentage of reduction of serum magnesium (p = 0.03). Conclusion Our findings suggest a highly variable response of the QTc interval duration and QTD to hemodialysis. The post-dialysis QTc interval duration inversely correlated with the decrease of both serum potassium and magnesium levels after dialysis. PMID:22470374

    The aim of this study was to evaluate the effect of electroacupuncture (EA) on postoperative pain management in patients undergoing thoracic surgery. A randomized study was conducted. Ninety-two thoracic surgical patients were randomly divided into an EA group and a sham group. Postoperative intravenous analgesia was applied with a half dose of the conventional drug concentration in both groups. In the EA group, EA treatment was administered for three consecutive days after the surgery with 6 sessions of 30 min each. Compared with the sham group, patients in the EA group had a lower visual analogue scale (VAS) score at 2, 24, 48, and 72 hours and consumed less analgesic after surgery. The incidence of opioid-related adverse effects of nausea was lower in the EA group. The time to first flatus and defecation was also shorter in the EA group. Furthermore, the plasma β-endorphin (β-EP) level was higher by radioimmunoassay and the plasma 5-hydroxytryptamine (5-HT) level was lower in the EA group by enzyme-linked immunosorbent assay during the first 72 hr after thoracic surgery. Therefore, EA is suitable as an adjunct treatment for postoperative pain management after thoracic surgery. PMID:27073400

    Aims: Spiritual concerns are being identified as important components of palliative care. The aim of this study was to explore the nature of spiritual concerns in cancer patients undergoing palliative care in a hospice in India. Materials and Methods: The methodology used was a qualitative method: Interpretive phenomenological analysis. A semi-structured interview guide was used to collect data, based on Indian and western literature reports. Certain aspects like karma and pooja, relevant to Hindus, were included. Theme saturation was achieved on interviewing 10 participants. Results: The seven most common spiritual concerns reported were benefit of pooja, faith in God, concern about the future, concept of rebirth, acceptance of one's situation, belief in karma, and the question Why me? No participant expressed four of the concerns studied: Loneliness, need of seeking forgiveness from others, not being remembered later, and religious struggle. Conclusions: This study confirms that there are spiritual concerns reported by patients receiving palliative care. The qualitative descriptions give a good idea about these experiences, and how patients deal with them. The study indicates the need for adequate attention to spiritual aspects during palliative care. PMID:24049350

    ABSTRACT Objective: to investigate the factors associated with mortality in patients undergoing coronary artery bypass grafting in a cardiovascular referral hospital in Santa Catarina. Method: quantitative, exploratory, descriptive and retrospective study. The medical records of 1447 patients, from 2005 to 2013, were analyzed for statistically related variables, these being: profile, hospitalization diagnosis, risk factors for coronary artery disease, complications recorded during the hospitalization, length of hospitalization and cause of death. Results: the mortality rate was 5.3% during the study period. Death was more common in females and those of black skin color, with a mean age of 65 years. Acute myocardial infarction was the most common hospitalization diagnosis. The majority of the complications recorded during hospitalization were characterized by changes in the cardiovascular system, with longer hospitalization periods being directly related to death from septic shock. Conclusion: the data provide subsidies for nursing work with preventive measures and early detection of complications associated with coronary artery bypass grafting. This reinforces the importance of using the data as quality indicators, aiming to guarantee care guided by reliable information to guide managers in planning patient care and high complexity health services.

    Objective this study had the aim of assessing the quality of life among patients undergoing total knee arthroplasty (TKA). For this, the SF-36 and WOMAC questionnaires respectively were used to make comparisons with preoperative values. Methods a prospective observational cohort study was conducted, with blinded analysis on the results from 107 TKAs in 99 patients, between June 2010 and October 2011. The present study included 55 knees/patients, among whom 73% were female and 27% were male. The patients’ mean age was 68 years. The SF-36 and WOMAC questionnaires (which have been validated for the Portuguese language) were applied immediately before and six months after the surgical procedure. Results the statistical and graphical analyses indicated that the variables presented normal distribution. From the data, it was seen that all the indices underwent positive changes after the surgery. Conclusions despite the initial morbidity, TKA is a very successful form of treatment for severe osteoarthritis of the knee (i.e. more than two joint compartments affected and/or Ahlback classification greater than 3), from a functional point of view, with improvement of the patients’ quality of life, as confirmed in the present study. This study presented evidence level IV (description of case series), with analysis on the results, without a comparative study. PMID:26229799

    Non-compliance has received significant attention in medicine, yet few studies have examined its correlates in autologous hematopoietic SCT (AHSCT) patients. This study examined predictors of non-compliance in a sample of 151 AHSCT patients treated in an outpatient setting. Before AHSCT, participants completed a validated measure of mood and retrospective chart reviews were conducted to assess non-compliance during AHSCT, defined as refusal of oral hygiene, prescribed exercise programs, oral nutrition and/or prescribed medications. We found 121 patients (80%) were non-compliant with an aspect of the AHSCT regimen on 1 or more days; mean percentage of non-compliant days was 16.6 (s.d. 15.6). Men were more likely than women to be non-compliant (P<0.05); as were participants with an elevated depression score (P<0.05). Stepwise regression models identified significant predictors of non-compliance: gender, depression, global distress and nausea and vomiting severity (P-values all <0.01). Further analysis revealed that the interaction of the psychological variables with gender was a more robust predictor of non-compliance (P<0.001). For outpatient AHSCT, our findings suggest the need to broaden conceptualizations of risk factors for non-compliance and the importance of assessing patient barriers to compliance to ensure optimal treatment outcome.

    BACKGROUND Perioperative hemorrhage impacts patient outcomes and health care resource utilization, yet the risks of transfusion therapies are significant. In patients with preoperative thrombocytopenia, the effects of prophylactic preoperative platelet (PLT) transfusion on perioperative bleeding complications remain uncertain. STUDY DESIGN AND METHODS This is a retrospective cohort study of noncardiac surgical patients between January 1, 2008, and December 31, 2011. Propensity-adjusted analyses were used to evaluate associations between preoperative thrombocytopenia, preoperative PLT transfusion, and the outcomes of interest, with a primary outcome of perioperative red blood cell (RBC) transfusion. RESULTS A total of 13,978 study participants were included; 860 (6.2%) had a PLT count of not more than 100 × 109/L with 71 (8.3%) receiving PLTs preoperatively. Administration of PLTs was associated with higher rates of perioperative RBC transfusion (66.2% vs. 49.1%, p 0.0065); however, in propensity-adjusted analysis there was no significant difference between groups (odds ratio [OR] [95% confidence interval {95% CI}], 1.68 [0.95–2.99]; p =0.0764]. Patients receiving PLTs had higher rates of intensive care unit (ICU) admission (OR [95% CI], 1.95 [1.10–3.46]; p =0.0224) and longer hospital lengths of stay (estimate [95% bootstrap CI], 7.2 [0.8–13.9] days; p =0.0006) in propensity-adjusted analyses. CONCLUSION Preoperative PLT transfusion did not attenuate RBC requirements in patients with thrombocytopenia undergoing noncardiac surgery. Moreover, preoperative PLT transfusion was associated with increased ICU admission rates and hospital duration. These findings suggest that more conservative management of preoperative thrombocytopenia may be warranted. PMID:26559936

    Catheter ablation for atrial fibrillation (AF) has emerged as a popular procedure. The purpose of this study was to examine whether there exist differences or disparities in ablation utilization across gender, socioeconomic class, insurance, or race. Using the Nationwide Inpatient Sample (2000 to 2012), we identified adults hospitalized with a principal diagnosis of AF by ICD 9 code 427.31 who had catheter ablation (ICD 9 code-37.34). We stratified patients by race, insurance status, age, gender, and hospital characteristics. A hierarchical multivariate mixed-effect model was created to identify the independent predictors of AF ablation. Among an estimated total of 3,508,122 patients (extrapolated from 20% Nationwide Inpatient Sample) hospitalized with a diagnosis of AF in the United States from the year 2000 to 2012, 102,469 patients (2.9%) underwent catheter ablations. The number of ablations was increased by 940%, from 1,439 in 2000 to 15,090 in 2012. There were significant differences according to gender, race, and health insurance status, which persisted even after adjustment for other risk factors. Female gender (0.83 [95% CI 0.79 to 0.87; p <0.001]), black (0.49 [95% CI 0.44 to 0.55; p <0.001]), and Hispanic race (0.64 [95% CI 0.56 to 0.72; p <0.001]) were associated with lower likelihoods of undergoing an AF ablation. Medicare (0.93, 0.88 to 0.98, <0.001) or Medicaid (0.67, 0.59 to 0.76, <0.001) coverage and uninsured patients (0.55, 0.49 to 0.62, <0.001) also had lower rates of AF ablation compared to patients with private insurance. In conclusion we found differences in utilization of catheter ablation for AF based on gender, race, and insurance status that persisted over time. PMID:26899494

    Background: Bilirubin is a potent antioxidant and previous studies have reported the relationship between low serum bilirubin concentration and atherosclerosis. Objective: To evaluate the prognostic value of serum total bilirubin (STB) in patients with angina pectoris undergoing percutaneous coronary intervention (PCI). Methods: In total of 1419 patients (931 men, mean age 60.9±10.5 years) with angina pectoris who had undergone successfully percutaneous coronary intervention (PCI) were included in this study. Patients were divided into 2 groups according to the median baseline STB (0.49 mg/dL in this cohort), which was measured before the PCI. Patients with a STB ≥0.49 mg/dL were classified into the high STB group and those with a STB <0.49 mg/dL were classified into the low STB group. Results: The incidence of in-hospital mortality and myocardial infraction was similar in the two groups. After a mean follow-up of 29.0±7.6 months, the incidence of death/myocardial infarction/stroke was significantly higher in low STB group compared with high STB group. Multivariate Cox regression analysis showed that low STB was an independent predictor of death/myocardial infarction/stroke (hazard ratio (HR) = 1.59, 95% confidence interval (CI) = 1.04-2.41, P = 0.031). The cumulative survival rate free from death/myocardial infarction/stroke was lower in low STB group than in high STB group (P = 0.002). Conclusion: Low STB levels before PCI is an independent predictor of long-term adverse clinical outcomes in patients with angina pectoris. PMID:26629096

    Home blood pressure (HBP) is an independent predictor of cardiovascular and renal function. However, no particular guidelines have been established for optimal HBP in peritoneal dialysis (PD) patients. Bioelectrical impedance analysis (BIA) is a beneficial tool for determining body composition. In the present study, we used BIA to determine body composition parameters that might play a role in the regulation of HBP in PD patients, and we compared HBP with office blood pressure (BP). Our study enrolled 15 patients (11 men, 4 women) receiving PD at Tohoku University Hospital, who, for 1 year, agreed to monitor HBP and to undergo body composition analysis. Patients were requested to measure HBP twice daily (morning, night) using a home BP device. A bioimpedance monitor was used to monitor body composition each month. Blood and urine samples were also analyzed each month. The relationships of average morning systolic HBP (sMHBP) with parameters of body composition and of blood and urine analyses were evaluated. The enrolledpatients were 66.3 ± 7.7 years of age and had a PD vintage of 28.3 ± 6.4 months. Overall, their sMHBP was 128 ± 13 mmHg and their office systolic BP was 126 ± 15 mmHg. Although office systolic BP and sMHBP both correlated with body fluid parameters [total body water (TBW)/height2], renal function (renal Kt/V serum creatinine), and heart function (left ventricular mass index), the correlation coefficient for sMHBP and TBW/height2 was highest, with sMHBP being the only independent predictor. Sodium intake was associated only with sMHBP. Our results suggest that body fluid status determined by BIA, heart and renal function, and sodium intake show better associations with sMHBP than with office systolic BP. Monitoring HBP and body composition by BIA are beneficial for the maintenance of volume status in PD patients.

    The influence of four different kinds of intravascular volume replacement on platelet function was investigated in 60 patients undergoing elective aortocoronary bypass grafting using cardiopulmonary bypass (CPB). In a randomized sequence, high-molecular weight hydroxyethyl starch solution (HMW-HES, mean molecular weight [Mw] 450,000 d), low-molecular weight HES (LMW-HES, Mw 200,000 d), 3.5% gelatin or 5% albumin were infused preoperatively to double reduced filling pressure (pulmonary capillary wedge pressure [PCWP] < 5 mm Hg). Fifteen untreated patients served as a control. Platelet function was assessed by aggregometry using turbidometric technique (inductors: ADP, epinephrine, collagen). Maximum aggregation, maximum gradient of aggregation, and platelet volume were measured before, during, and after CPB until the first postoperative day. HMW-HES 840 +/- 90 mL, LMW 850 +/- 100 mL, gelatin 950 +/- 110 mL, and albumin 810 +/- 100 mL were given preoperatively. Maximum platelet aggregation (ranging from -23% to -44% relative from baseline value) and maximum gradient of platelet aggregation (ranging from -26% to -45% relative from baseline values) were reduced only in the HMW-HES patients. After CPB, aggregometry also was impaired most markedly in these patients. The other volume groups showed less reduction in platelet aggregation and were similar to the untreated control. On the first postoperative day, aggregation variables had returned almost to baseline in all patients. Platelet volume was the same among the groups within the investigation period. Postbypass blood loss was highest in the HMW-HES group (890 +/- 180 mL). There was significant (P < 0.04) correlation in this group between blood loss and change in platelet aggregation.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7684579

    Walking ability is significantly lower in hemodialysis patients compared to healthy people. Decreased walking ability characterized by slow walking speed is associated with adverse clinical events, but determinants of decreased walking speed in hemodialysis patients are unknown. The purpose of this study was to identify factors associated with slow walking speed in ambulatory hemodialysis patients. Subjects were 122 outpatients (64 men, 58 women; mean age, 68 years) undergoing hemodialysis. Clinical characteristics including comorbidities, motor function (strength, flexibility, and balance), and maximum walking speed (MWS) were measured and compared across sex-specific tertiles of MWS. Univariate and multivariate logistic regression analyses were performed to examine whether clinical characteristics and motor function could discriminate between the lowest, middle, and highest tertiles of MWS. Significant and common factors that discriminated the lowest and highest tertiles of MWS from other categories were presence of cardiac disease (lowest: odds ratio [OR] = 3.33, 95% confidence interval [CI] = 1.26–8.83, P<0.05; highest: OR = 2.84, 95% CI = 1.18–6.84, P<0.05), leg strength (OR = 0.62, 95% CI = 0.40–0.95, P<0.05; OR = 0.57, 95% CI = 0.39–0.82, P<0.01), and standing balance (OR = 0.76, 95% CI = 0.63–0.92, P<0.01; OR = 0.81, 95% CI = 0.68–0.97, P<0.05). History of fracture (OR = 3.35, 95% CI = 1.08–10.38; P<0.05) was a significant factor only in the lowest tertile. Cardiac disease, history of fracture, decreased leg strength, and poor standing balance were independently associated with slow walking speed in ambulatory hemodialysis patients. These findings provide useful data for planning effective therapeutic regimens to prevent decreases in walking ability in ambulatory hemodialysis patients. PMID:27018891

    Purpose: To establish an organ dose database for pediatric and adolescent reference individuals undergoing computed tomography (CT) examinations by using Monte Carlo simulation. The data will permit rapid estimates of organ and effective doses for patients of different age, gender, examination type, and CT scanner model. Methods: The Monte Carlo simulation model of a Siemens Sensation 16 CT scanner previously published was employed as a base CT scanner model. A set of absorbed doses for 33 organs/tissues normalized to the product of 100 mAs and CTDI{sub vol} (mGy/100 mAs mGy) was established by coupling the CT scanner model with age-dependent reference pediatric hybrid phantoms. A series of single axial scans from the top of head to the feet of the phantoms was performed at a slice thickness of 10 mm, and at tube potentials of 80, 100, and 120 kVp. Using the established CTDI{sub vol}- and 100 mAs-normalized dose matrix, organ doses for different pediatric phantoms undergoing head, chest, abdomen-pelvis, and chest-abdomen-pelvis (CAP) scans with the Siemens Sensation 16 scanner were estimated and analyzed. The results were then compared with the values obtained from three independent published methods: CT-Expo software, organ dose for abdominal CT scan derived empirically from patient abdominal circumference, and effective dose per dose-length product (DLP). Results: Organ and effective doses were calculated and normalized to 100 mAs and CTDI{sub vol} for different CT examinations. At the same technical setting, dose to the organs, which were entirely included in the CT beam coverage, were higher by from 40 to 80% for newborn phantoms compared to those of 15-year phantoms. An increase of tube potential from 80 to 120 kVp resulted in 2.5-2.9-fold greater brain dose for head scans. The results from this study were compared with three different published studies and/or techniques. First, organ doses were compared to those given by CT-Expo which revealed dose

  20. Activation of monocytes and cytokine production in patients with peripheral atherosclerosis obliterans

    PubMed Central

    2011-01-01

    Background Arterial peripheral disease is a condition caused by the blocked blood flow resulting from arterial cholesterol deposits within the arms, legs and aorta. Studies have shown that macrophages in atherosclerotic plaque are highly activated, which makes these cells important antigen-presenting cells that develop a specific immune response, in which LDLox is the inducing antigen. As functional changes of cells which participate in the atherogenesis process may occur in the peripheral blood, the objectives of the present study were to evaluate plasma levels of anti-inflammatory and inflammatory cytokines including TNF-α, IFN-γ, interleukin-6 (IL-6), IL-10 and TGF-β in patients with peripheral arteriosclerosis obliterans, to assess the monocyte activation level in peripheral blood through the ability of these cells to release hydrogen peroxide (H2O2) and to develop fungicidal activity against Candida albicans (C. albicans) in vitro. Methods TNF-α, IFN-γ, IL-6, IL-10 and TGF-β from plasma of patients were detected by ELISA. Monocyte cultures activated in vitro with TNF-alpha and IFN-gamma were evaluated by fungicidal activity against C. albicans by culture plating and Colony Forming Unit (CFU) recovery, and by H2O2 production. Results Plasma levels of all cytokines were significantly higher in patients compared to those detected in control subjects. Control group monocytes did not release substantial levels of H2O2 in vitro, but these levels were significantly increased after activation with IFN-γ and TNF-α. Monocytes of patients, before and after activation, responded less than those of control subjects. Similar results were found when fungicidal activity was evaluated. The results seen in patients were always significantly smaller than among control subjects. Conclusions: The results revealed an unresponsiveness of patient monocytes in vitro probably due to the high activation process occurring in vivo as corroborated by high plasma cytokine levels

    The purpose of this study was to evaluate the usefulness of the neutrophil to lymphocyte ratio (NLR) in a differential diagnosis and follow-up of patients with peripheral vertigo. Twenty patients with benign positional paroxysmal vertigo (BPPV) and 20 patients diagnosed with vestibular neuritis (VN) were included in the study. Serum samples were analysed at the initial presentation and on the seventh day of admission retrospectively. The WBC (white blood cell) count was 10500±2100 /mm3, the neutrophil count was 4700±1100/mm3, the lymphocyte count was 5000±1200/mm3 and the NLR was 0.9±0.2 in the VN group. In patients with BPPV, the WBC count was 9200±1300/mm3, the neutrophil count was 5200±1200/mm3, the lymphocyte count was 3100±1200/mm3 and the NLR was 1.9±0.9. The NLR was lower in patients with VN than in patients diagnosed with BPPV. The WBC and lymphocyte count was significantly higher in the patients with VN than in the patients diagnosed with BPPV. Within the first week of admission, the WBC and lymphocyte counts in patients with VN decreased, and the NLR was more elevated than at the admission. It is highly recommended that NLR is used in the diagnosis and follow-up of the most commonly observed aetiological factors of peripheral vertigo, BPPV and VN. PMID:27661276

    Background and study aims: Biliary and pancreatic diseases are common in the elderly; however, few studies have addressed the occurrence of adverse events in elderly patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). Our objective was to determine the incidence rates of specific adverse events in this group and calculate incidence rate ratios (IRRs) for selected comparison groups. Patients and methods: Bibliographical searches were conducted in Medline, EMBASE, and Cochrane library databases. The studies included documented the incidence of adverse events (perforation, pancreatitis, bleeding, cholangitis, cardiopulmonary adverse events, mortality) in patients aged ≥ 65 who underwent ERCP. Pooled incidence rates were calculated for each reported adverse event and IRRs were determined for available comparison groups. A parallel analysis was performed in patients aged ≥ 80 and ≥ 90. Results: Our literature search yielded 7429 articles, of which 69 studies met our inclusion criteria. Pooled incidence rates for adverse events (per 1000 ERCPs) in patients aged ≥ 65 were as follows: perforation 3.8 (95 %CI 1.8 – 7.0), pancreatitis 13.1 (95 %CI 11.0 – 15.5), bleeding 7.7 (95 %CI 5.7 – 10.1), cholangitis 16.1 (95 %CI 11.7 – 21.7), cardiopulmonary events 3.7 (95 %CI 1.5 – 7.6), and death 7.1 (95 %CI 5.2 – 9.4). Patients ≥ 65 had lower rates of pancreatitis (IRR 0.3, 95 %CI 0.3 – 0.4) compared with younger patients. Octogenarians had higher rates of death (IRR 2.4, 95 %CI 1.3 – 4.5) compared with younger patients, whereas nonagenarians had increased rates of bleeding (IRR 2.4, 95 %CI 1.1 – 5.2), cardiopulmonary events (IRR 3.7, 95 %CI 1.0 – 13.9), and death (IRR 3.8, 95 %CI 1.0 – 14.4). Conclusions ERCP appears to be safe in elderly patients, except in the very elderly who are at higher risk of some adverse events. These data on adverse

    Purpose We sought to determine whether human epidermal growth factor receptor 2 (HER2) and vascular endothelial growth factor (VEGF) expression were independent prognostic factors for gastric cancer (GC). Patients and methods A total of 678 consecutive patients with GC undergoing curative surgery between October 2010 and December 2012 had resected tissue examined for HER2 and VEGF expression using immunohistochemistry. Immunohistochemical expression of HER2 was analyzed using the DAKO-HercepTest™ and scored according to published reports. VEGF expression was calculated by multiplying the score for the percentage of positive cells by the intensity score. We defined positive expression as a score of 1+, 2+, or 3+, and a score of 0 was defined as negative expression. We compared these results to clinicopathological characteristics, including overall survival (OS). Results Multivariate analysis revealed that HER2 expression was independently associated with shorter OS (hazard ratio [HR], 1.55; 95% confidence interval [CI], 1.10–2.18; P=0.01) and with higher tumor–nodes–metastasis stage (HR, 3.88; 95% CI, 2.67–5.64; P<0.001) in patients with GC. VEGF expression was not associated with OS (HR, 1.25; 95% CI, 0.86–1.82; P=0.24). HER2 expression was still identified as an independent prognostic factor in Stage II–III patients treated with surgery and adjuvant chemotherapy (P=0.004) but not in patients who received surgery alone (P=0.61). Among patients with Stage III GC, those without HER2 expression survived longer with adjuvant chemotherapy (median 43.9 vs 32.2 months, respectively; P=0.04), whereas those with HER2 expression did not (median 37.1 vs 33.9 months, respectively; P=0.67). Conclusion HER2 expression is independently associated with OS in GC, especially in patients who are at higher risk and receive adjuvant chemotherapy after curative resection. HER2 expression may have important clinical utility in directing adjuvant treatment for Stage III GC

    Background Malnutrition is highly prevalent in patients undergoing liver transplantation and has been associated to various clinical variables and outcome of the surgery. Methods We recruited 54 adult patients undergoing living donor liver transplant (LT) as study sample. Nutrition assessment was performed by body mass index (BMI), BMI for ascites, albumin, subjective global assessment (SGA) and anthropometry [mid upper arm circumference (MUAC), mid arm muscle circumference (MAMC), and triceps skin-fold (TSF)], Hand Grip strength, and phase angle of the body. Prevalence and comparison of malnutrition was performed with various clinical variables: aetiology, Child Turcotte Pugh scores and model for end stage liver disease (ESLD) grades, degree of ascites, blood product usage, blood loss during the surgery, mortality, days [intensive care unit (ICU), Ventilator and Hospital], and Bio-impedance analysis [weight, fat mass, fat free mass (FFM), muscle mass and body fat%]. Results Assessment of nutrition status represents a major challenge because of complications like fluid retention, hypoalbuminemia and hypoproteinemia. Different nutrition assessment tools show great disparity in the level of malnutrition among ESLD patients. In the present study recipient nutrition status evaluation by different nutrition assessment tools used showed malnutrition ranging from 3.7% to 100%. BMI and anthropometric measurements showed lower prevalence of malnutrition than phase angle and SGA whereas hand grip strength showed 100% malnutrition. Agreement among nutrition assessment methods showed moderate agreement (κ=0.444) of SGA with phase angle of the body. Malnutrition by different assessment tools was significantly associated to various clinical variables except MELD and days (ICU, Ventilator and Hospital). SGA was significantly (P<0.05) associated to majority of the clinical variables like aetiology, child Turcotte Pugh grades, degree of ascites, blood product usage, blood loss

    Surgical resection continues to be the mainstay of treatment for rectal cancer. Neoadjuvant therapy (chemotherapy and radiation) has also been shown to be efficacious. The impact of preoperative chemotherapy and radiation on postoperative complications is unclear. The purpose of this study is to evaluate the relationship of neoadjuvant therapy on postoperative complications in patients undergoing a resection of rectal cancer. A total of 325 patients who underwent curative resection for rectal cancer from 1984 to 2001 were retrospectively reviewed. Only cases with complete data sets who had undergone surgery at this institution were evaluable (257). The patients were divided into groups based on the operative procedure performed; abdominoperineal resection (APR) versus sphincter-sparing (SS) procedures (LAR/Transanal) and whether or not preoperative chemotherapy or radiation was administered. There was no significant difference between complication rates for APR and SS with 19 per cent and 14 per cent, respectively. The preoperative therapy had no effect on complications after APR. However, the SS group showed 21 per cent of the patients who received radiation had complications compared to 11 per cent in those who did not (P = 0.087). Complications in the SS group included leaks, wound infections, abscess, embolism, cardiac dysrhythmias, and myocardial infarctions. The 30-day mortality was 1.9 per cent for the entire cohort with no clear difference between groups. There was no significant difference in complication rate between APR and SS. In the APR group, neoadjuvant therapy had no impact on the incidence of complications. However, the SS group did show a trend between preoperative chemotherapy and radiation and complication rate. However, this may not outweigh the advantages of preoperative therapy in this setting.

    BACKGROUND: Increase in intraocular pressure (IOP) following tracheal intubation during general anesthesia can be troublesome. We compared the influence of two muscle relaxants, cisatracurium and atracurium, on IOP in patients undergoing general anesthesia. METHODS: This randomized, double-blind, comparative trial was conducted on 90 candidates for elective non-ophthalmic surgery under general anesthesia. Patients were 18 to 60 years old with the American Society of Anesthesiologists (ASA) class of I or II. Anesthesia was induced with fentanyl (1.5 mg/kg) and sodium thiopental (5 mg/kg). Patients received atracurium (0.5 mg/kg) or cisatracurium (0.15 mg/kg) two minutes prior to tracheal intubation. IOP, systolic (SBP) and diastolic blood pressure (DBP), and heart rate (HR) were measured at baseline (before medication), after medication (before intubation), and 2, 5, and 10 minutes after intubation. RESULTS: In both groups IOP decreased after administration of muscle relaxants (-3.3 ± 3.6 mmHg), then increased 2 minutes after intubation (5.5 ± 4.4 mmHg), but decreased 5 (-3.3 ± 3.3 mmHg) and 10 (-0.5 ± 2.6 mmHg) minutes after intubation. IOP and SBP were significantly higher in the atracurium compared with the cisatracurium group after 2 (p < 0.001 and 0.002, respectively), 5 (p < 0.001 and 0.012, respectively), and 10 (p = 0.02 and 0.048, respectively) minutes after intubation. CONCLUSIONS: Compared with atracurium, administration of cisatracurium can better prevent the increase of IOP following tracheal intubation in general anesthesia. The observed difference might be related to different effects on hemodynamic variables. Application of these results in patients under ophthalmic surgery is warranted. PMID:22247724

    Background: Patients with breast cancer have an impaired cardiorespiratory fitness, in part, due to the toxic effects of anticancer therapy. Physical exercise as a means of rehabilitation for patients with cancer is an emerging area of research and treatment, emphasizing the need for accurate and feasible physical capacity measurements. The purpose of this study was to evaluate the validity of peak oxygen consumption (o2peak) predicted by the Ekblom-Bak test (E-B) and the Åstrand-Rhyming prediction model (A-R). Methods: Eight patients with breast cancer undergoing chemotherapy participated in the study. Submaximal exercise tests were performed at 2 different submaximal workloads. Estimated o2peak values were obtained by inserting the heart rate (HR) from the 2 workloads into the E-B prediction model and the HR of only the higher workload into the Åstrand nomogram. A 20-W incremental cycle test-to-peak effort was performed to obtain o2peak values. Results: Results from A-R overestimated o2peak by 6% (coefficient of variation = 7%), whereas results from E-B overestimated o2peak with 42% (coefficient of variation = 21%) compared with measured o2peak. Pearson's correlation coefficient revealed a significant strong relationship between the estimated o2peak from A-R and the measured o2peak (r = 0.86; P < .05), whereas the relationship between the estimated o2peak from E-B and the measured o2peak resulted in a nonsignificant weak correlation (r = 0.21). Conclusion: In a situation where maximal exercise testing is not practical or undesirable from a patient safety perspective, submaximal exercise testing provides an alternative way of estimating o2peak. The A-R prediction model appears to be a valid submaximal exercise test for determining cardiorespiratory fitness in this population.

    Introduction The frequency of surgical procedures has increased steadily in recent decades, including the myocardial revascularization. Objectives To demonstrate the importance of physiotherapy in the preoperative period of cardiac surgery in relation to the reduction of hospital stay, changes in lung volumes and respiratory muscle strength. Methods We conducted a prospective study with patients undergoing myocardial revascularization, the Hospital das Clínicas da Universidade Estadual Paulista (UNESP)/Botucatu - SP. We evaluated 70 patients of both genders, aged between 40 and 75 years, subdivided into two groups: group I - 35 patients of both genders, who received a written protocol guidance, breathing exercises and respiratory muscle training in the preoperative period and group II - 35 patients of both genders, who received only orientation of the ward on the day of surgery. This study was approved by the Ethics Committee of UNESP / Botucatu - SP. Results Maximal inspiratory pressure in third postoperative day and fifth postoperative day and significant difference between groups, being better for the intervention group. Expiratory pressure was significant in fifth postoperative day in the intervention group compared to controls. The difference of length of hospital stay in the postoperative was found between the groups with shorter hospital stay in the group receiving preoperative therapy. Conclusion Physical therapy plays an important role in the preoperative period, so that individuals in the intervention group more readily restored the parameters evaluated before surgery, in addition, there was a decrease in the time of the postoperative hospital stay. Thus, it is thought the cost-effectiveness of a program of preoperative physiotherapy. PMID:25140472

    We developed computational methods and tools to assess organ doses for pediatric and adult patients undergoing computed tomography (CT) examinations. We used the International Commission on Radiological Protection (ICRP) reference pediatric and adult phantoms combined with the Monte Carlo simulation of a reference CT scanner to establish comprehensive organ dose coefficients (DC), organ absorbed dose per unit volumetric CT Dose Index (CTDIvol) (mGy/mGy). We also developed methods to estimate organ doses with tube current modulation techniques and size specific dose estimates. A graphical user interface was designed to obtain user input of patient- and scan-specific parameters, and to calculate and display organ doses. A batch calculation routine was also integrated into the program to automatically calculate organ doses for a large number of patients. We entitled the computer program, National Cancer Institute dosimetry system for CT(NCICT). We compared our dose coefficients with those from CT-Expo, and evaluated the performance of our program using CT patient data. Our pediatric DCs show good agreements of organ dose estimation with those from CT-Expo except for thyroid. Our results support that the adult phantom in CT-Expo seems to represent a pediatric individual between 10 and 15 years rather than an adult. The comparison of CTDIvol values between NCICT and dose pages from 10 selected CT scans shows good agreements less than 12% except for two cases (up to 20%). The organ dose comparison between mean and modulated mAs shows that mean mAs-based calculation significantly overestimates dose (up to 2.4-fold) to the organs in close proximity to lungs in chest and chest-abdomen-pelvis scans. Our program provides more realistic anatomy based on the ICRP reference phantoms, higher age resolution, the most up-to-date bone marrow dosimetry, and several convenient features compared to previous tools. The NCICT will be available for research purpose in the near future.

    Background Radiation therapy is a therapeutic modality widely used for treatment of upper aerodigestive tract (UADT) neoplasms. However, its action is not restricted to tumor cells, and it may cause a variety of adverse reactions, including reduced jaw mobility. Material and Methods A prospective cohort study was conducted to assess changes in jaw mobility in patients with UADT cancer undergoing radiation therapy. Results Fifty-six patients completed the study. The results showed a significant reduction in mouth opening (p<0.001), right lateral excursion (p=0.038) and left lateral excursion (p=0.035) of the jaw, a significant increase in the presence (p<0.001) and severity of oral mucositis (p<0.001), and a significant decrease in performance status (p<0.001) after radiation therapy. Thirty-six patients (64.3%) exhibited reduction in mouth opening after treatment. The variables significantly associated with mouth opening reduction on bivariate analysis were: modification of diet (p=0.037), radiation field (p=0.024), presence of mucositis (p=0.003), and reduction in performance status (p=0.007). After adjustment by the multivariate model, the only variables that remained significantly associated with reduction in mouth opening were presence of mucositis (p=0.018) and reduction in performance status (p=0.47). Conclusions These findings indicate that patients with upper aerodigestive tract cancer experience reduced jaw mobility after radiation therapy, which is strongly correlated with mucositis and reduced functional ability. Key words:Head and neck neoplasms, vertical dimension, radiation therapy, mucositis, temporomandibular joint, joint range of motion, trismus. PMID:26449427

    A 32-year-old Indian female 38 weeks pregnant, with a history of multiple sclerosis since 2008 was admitted in obstetric ward for safe confinement. She had a history of diminution of vision in both eyes and limb weakness, relapsing – remitting type with movement-induced muscle spasms, in all the four limbs. Her symptoms were usually diplopia, difficulty in vision and ataxic gait. Sh was then treated with methylprednisolone. She was on oral dimethyl fumarate trial, which was stopped at the beginning of pregnancy. Presently, she was completely asymptomatic. Epidural anesthesia with an indwelling catheter was administered with 15 ml of 0.25% bupivacaine in 5 ml increments. A total of 3 mg of epidural morphine was given for post-operative analgesia. The surgery evolved without any intercurrences and patient was discharged from the hospital 72 h after surgery without worsening of her symptoms. We report a safe anesthetic management of a patient with MS undergoing cesarean section with low dose epidural bupivacaine with the addition of morphine for post-operative analgesia. PMID:25191198

    Clindamycin was given intravenously to 15 patients undergoing colorectal surgery in an initial dose of 600 mg, given at induction of anesthesia followed by 6 doses of 600 mg at 8-h intervals. Series of serum samples and fecal specimens were taken for analysis of clindamycin concentrations. Tissue samples from the gut wall were taken at surgery. The highest serum concentrations observed occurred 30 min after administration of clindamycin and varied between 6.8 and 37.9 microgram/ml (mean, 14.8 +/- 2.0 [standard error] microgram/ml). The clindamycin concentrations in the tissue samples were between 1.8 and 13.0 microgram/g. Clindamycin concentration in the fecal samples varied between 2.1 and 460 microgram/g. Fecal samples were also collected during the investigation period for cultivation of aerobic and anaerobic bacteria. Among the aerobic bacteria, enterococci and streptococci decreased during the prophylaxis period. Anaerobic bacteria also decreased significantly during the same period. After the clindamycin administration period, enterococci, streptococci and anaerobic bacteria proliferated. No anaerobic strains resistant to clindamycin were isolated. Postoperative infections due to Streptococcus faecalis and different enterobacteria such as Escherichia coli, Enterobacter cloacae, Citrobacter freundii, and Klebsiella occurred in five patients.

    Procedures for the surgical correction of dentofacial deformities may produce important complications, whether due to the potential for vascular injury or to prolonged surgery, both of which may lead to severe blood loss. Fluid replacement with crystalloid, colloid, or even blood products may be required. The aim of this study was to assess blood loss and transfusion requirements in 45 patients (18 males and 27 females; mean age 29.29 years, range 16-52 years) undergoing orthognathic surgery, assigned to one of two groups according to procedure type-rapid maxillary expansion or double-jaw orthognathic surgery. Preoperative hemoglobin and hematocrit levels and intraoperative blood loss were measured. There was a substantial individual variation in pre- and postoperative hemoglobin values (10.3-17 and 8.8-15.4 g/dL, respectively; p < 0.05). Mean hematocrit values were 41.53 % preoperatively (range 31.3-50.0 %) and 36.56 % postoperatively (range 25-43.8 %) (p < 0.05). Mean blood loss was 274.60 mL (range 45-855 mL). Only two patients required blood transfusion. Although blood loss and transfusion requirements were minimal in the present study, surgical teams should monitor the duration of surgery and follow meticulous protocols to minimize the risks.

    Pulmonary and systemic organ injury produced by oxidative stress including lipid peroxidation is a fundamental tenet of ischemia-reperfusion injury, inflammatory response to cardiac surgery, and cardiopulmonary bypass (CPB) but is not routinely measured in a surgically relevant time frame. To initiate a paradigm shift toward noninvasive and real-time monitoring of endogenous lipid peroxidation, we have explored pulmonary excretion and dynamism of exhaled breath ethylene during cardiac surgery to test the hypothesis that surgical technique and ischemia-reperfusion triggers lipid peroxidation. We have employed laser photoacoustic spectroscopy to measure real-time trace concentrations of ethylene from the patient breath and from the CPB machine. Patients undergoing aortic or mitral valve surgery-requiring CPB (n = 15) or off-pump coronary artery bypass surgery (OPCAB) (n = 7) were studied. Skin and tissue incision by diathermy caused striking (>30-fold) increases in exhaled ethylene resulting in elevated levels until CPB. Gaseous ethylene in the CPB circuit was raised upon the establishment of CPB (>10-fold) and decreased over time. Reperfusion of myocardium and lungs did not appear to enhance ethylene levels significantly. During OPCAB surgery, we have observed increased ethylene in 16 of 30 documented reperfusion events associated with coronary and aortic anastomoses. Therefore, novel real-time monitoring of endogenous lipid peroxidation in the intraoperative setting provides unparalleled detail of endogenous and surgery-triggered production of ethylene. Diathermy and unprotected regional myocardial ischemia and reperfusion are the most significant contributors to increased ethylene. PMID:25128523

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

    Abstract Introduction: Patients with dentofacial deformities may undergo orthodontic or orthodontic-surgical treatment. Both modalities can affect esthetics. Objective: This study aims to evaluate clinical and radiographic changes in exposure of maxillary central incisors occurring after orthognathic surgery for maxillary advancement. Methods: A total of 17 patients who underwent orthognathic surgery for maxillary advancement between September, 2010 and July, 2011 were selected. Exposure of maxillary central incisors was evaluated clinically and by lateral cephalograms. Measurements were taken one week before and three months after surgery. Data were paired in terms of sex, age, nasolabial angle, height and thickness of the upper lip, the amount of maxillary advancement, clinical exposure and inclination of maxillary central incisor by statistical tests (CI 95%). Results: After maxillary advancement, incisor clinical exposure had increased even with relaxed lips and under forced smile. Moreover, there was a mean increase of 23.33% revealed by lateral cephalograms. There was an inverse correlation between upper lip thickness and incisors postsurgical exposure revealed by radiographic images (p = 0.002). Conclusions: Significant changes in the exposure of maxillary central incisors occur after maxillary advancement, under the influence of some factors, especially lip thickness. PMID:26691970

    Aims: The SYNTAX score correlate with major cardiovascular events post-revascularization, although the histopathological basis is unclear. We aim to evaluate the association between syntax score and extracellular matrix histological characteristics of aortic punch tissue obtained during coronary artery bypass surgery (CABG). This analysis compares coronary artery bypass surgery patients with High and Low syntax score which were followed up for one year period. Methods and Results: Patients with High (score ≥ 33, (n=77)) and Low Syntax Scores (score ≤ 22, (n=71)) undergoing elective CABG were recruited prospectively. Baseline clinical characteristics and surgical risks were well matched. At 1 year, EMACCE (Sum of cardiovascular death, stroke, congestive cardiac failure, and limb, gut and myocardial ischemia) was significantly elevated in the High syntax group (P=0.022). Mass spectrometry (MS)-based quantitative iTRAQ proteomic results validated on independent cohort by immunohistochemistry (IHC) revealed that the High syntax group had significantly upraised Collagen I (P<0.0001) and Elastin (P<0.0001) content in ascending aortic wall. Conclusion: This study shows that aortic extracellular matrix (ECM) differ between High and Low syntax groups with up-regulation of Collagen I and Elastin level in High Syntax Score group. This identifies aortic punches collected during CABG as another biomarker source related with atherosclerosis severity and possible clinical outcome. PMID:27347220

    Previous studies showed that decreased cerebral saturation during cardiac surgery is related to adverse postoperative outcome. Therefore, we investigated the influence of intraoperative events on cerebral tissue saturation in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). A total of 52 adult patients who underwent cardiac surgery using pulsatile CPB were included in this prospective explorative study. Cerebral tissue oxygen saturation (SctO2) was measured in both the left and right cerebral hemisphere. Intraoperative events, involving interventions performed by anesthesiologist, surgeon, and clinical perfusionist, were documented. Simultaneously, in-line hemodynamic parameters (partial oxygen pressure, partial carbon dioxide pressure, hematocrit, arterial blood pressure, and CPB flow rates) were recorded. Cerebral tissue saturation was affected by anesthetic induction (p < .001), placement of the sternal retractor (p < .001), and initiation (p < .001) as well as termination of CPB (p < .001). Placement (p < .001) and removal of the aortic cross-clamp (p = .026 for left hemisphere, p = .048 for right hemisphere) led to changes in cerebral tissue saturation. In addition, when placing the aortic crossclamp, hematocrit (p < .001) as well as arterial (p = .007) and venous (p < .001) partial oxygen pressures changed. Cerebral tissue oximetry effectively identifies changes related to surgical events or vulnerable periods during cardiac surgery. Future studies are needed to identify methods of mitigating periods of reduced cerebral saturation.
