    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.

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

    The combination of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is a promising treatment option for selected patients with peritoneal carcinomatosis. This retrospective study investigated the relationship between baseline nutritional assessment with subsequent parenteral nutritional (PN) and clinical outcomes in cancer patients undergoing CRS and HIPEC. A consecutive series of 60 patients undergoing CRS and HIPEC at our institution between January 2009 and May 2011. Subjective Global Assessment (SGA) was used to assess nutritional status. Patients were classified preoperatively as: well nourished (SGA-A), mildly-moderately malnourished (SGA-B), and severely malnourished (SGA-C). For PN, patients were divided into 2 groups: those who received PN (PN+) and those who did not receive PN (PN-). The primary outcomes of interest were length of stay (LOS), postoperative complications, ECOG performance status (PS) and survival. LOS was calculated as the number of days in the hospital post surgery. Performance status was measured on a scale of 0-4. Survival was calculated from the date of first visit to the date of death/last contact. Of 60 patients, 19 were males and 41 females. The mean age at presentation was 50.3 years. The most common cancer types were colorectal (n = 24) and gynecologic (n = 19) with the majority of patients (n = 47) treated previously before coming to our institution. 33 patients were SGA-A, 22 SGA-B and 5 SGA-C prior to surgery. Of a total of 60 patients, 31 received PN. Mean LOS for the entire cohort was 16.2 days (SD = 9.8). Mean LOS for preoperative SGA-A, SGA-B and SGA-C were 15.0, 15.2 and 27.8 days respectively (ANOVA p = 0.02). Overall incidence of complications was 26.7% (16/60). Complications were recorded in 9 of 33 (27.3%) preoperative SGA-A patients and 7 of 27 (25.9%) SGA-B + C patients (p = 0.91). The median overall survival was 17.5 months (95% CI = 13.0 to 22

    Radiation dose to the brain and subsequent lifetime risk of diagnosis of radiation-related brain tumors were estimated for pediatric patients undergoing intracranial embolization. Average dose to the whole brain was calculated using dosimetric data from the Radiation Doses in Interventional Radiology Study for 49 pediatric patients who underwent neuroradiological procedures, and lifetime risk of developing radiation-related brain tumors was estimated using published algorithms based on A-bomb survivor data. The distribution of absorbed dose within the brain can vary significantly depending on field size and movement during procedures. Depending on the exposure conditions and age of the patient, organ-averaged brain dose was estimated to vary from 6 to 1600 mGy. The lifetime risk of brain tumor diagnosis was estimated to be increased over the normal background rates (57 cases per 10,000) by 3 to 40% depending on the dose received, age at exposure, and gender. While significant uncertainties are associated with these estimates, we have quantified the range of possible dose and propagated the uncertainty to derive a credible range of estimated lifetime risk for each subject. Collimation and limiting fluoroscopy time and dose rate are the most effective means to minimize dose and risk of future induction of radiation-related tumors. PMID:18959462

    Background Context. Products that can reduce development of epidural fibrosis may reduce risk for ongoing pain associated with development of scar tissue and make subsequent epidural reexploration easier. Purpose. To evaluate the use of dehydrated human amnion/chorion membrane (dHACM) on the formation of soft tissue scarring in the epidural space. Study Design. Case series. Patient Sample. Five patients having transforaminal lumbar interbody lumbar fusion (TLIF) with posterior instrumentation and implantation of dHACM in the epidural space and subsequent epidural reexploration. Outcome Measures. Degree of scar tissue adjacent to the epidural space at reexploration. Intraoperative and postoperative complications related to dHACM and patient reported outcomes. Methods. The degree of scar tissue adjacent to the epidural space was assessed during the reexploration surgery. Patients' outcomes were collected using standard validated questionnaires. Results. Four of 5 cases had easily detachable tissue during epidural reexploration. Angiolipoma of 10% was noted in 1 case and 5% in 2 cases. Significant improvements in patient reported outcomes were observed. No intraoperative or postoperative complications occurred. Conclusions. Our findings suggest that dHACM implant during TLIF may have favorable effects on epidural fibrosis and is well tolerated. Further studies with larger cohorts are required to prove our results.

    It is difficult to accurately forecast the clinical course of many patients presenting with mild cognitive problems. The utility in prognostic evaluation of various parameters of brain structure and function that can now be noninvasively measured remains to be clearly defined. The present work examined the value of regional cerebral metabolism, assessed with positron emission tomography (PET) and [(18)F]fluoro-2-deoxyglucose, in this context. PET scans of 167 patients (mean Mini-Mental State Examination (MMSE)=24 of 30 possible points) were classified as being positive or negative for evidence of progressive dementia. Results of scans were compared to patients' subsequent clinical course in general and in particular, to their changes in MMSE scores, for up to 10 years following PET. Data were further stratified according to the predictions of referring physicians based upon clinical assessments that had been performed up until the time of PET. Among those patients for whom a progressive dementing course had been predicted by PET criteria (but not those who were predicted by PET criteria to remain stable) a significant decline in general cognitive performance and MMSE scores occurred in the period following PET. Among those patients predicted by clinical criteria to have a progressive dementing illness, 94% of those with positive PET scans did suffer a progressive decline, while only 25% of those with negative scans progressed (relative risk 3.8). Similarly, among those patients who had been predicted by clinical criteria to remain cognitively stable, 74% of those with positive PET scans nevertheless suffered progressive decline, compared with 4% of those with negative PET scans (relative risk 18.4). These data indicate that evaluation of brain metabolism by PET in appropriately selected patients may improve the accuracy of clinical prognostic assessment.

    A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was how long chest drains should be left in place following video-assisted thoracic surgery (VATS) pleurodesis for primary spontaneous pneumothorax. Altogether, a total of 730 papers were found using the reported search, of which eight represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. We report that the main determining factor for the length of hospital stay following VATS pleurodesis is chest-drain duration. Providing no postoperative complications occur, and chest X-ray appearances of lung inflation are satisfactory, there is no documented contraindication to removing chest drains as early as 2 days postoperatively, with discharge the following day. Furthermore, leaving chest drains on water seal after a brief period of suction has been shown to benefit in reducing postoperative chest-drain duration and subsequent hospital stay. There is a paucity of literature directly addressing early vs late chest-drain removal protocols in this patient group. Hence, we conclude that, in clinical practice, the decision of when to remove chest drains postoperatively should remain guided empirically towards the individual patient.

    There are a growing number of reports of unresectable, advanced colorectal cancer and multiorgan invasive colorectal cancer for which extended surgery was avoided or a radical operation was performed after down-staging, or tumor size reduction, was achieved by chemotherapy. Here we describe a case of sigmoid colon cancer (cStage IV) for which preoperative chemotherapy improved the outcome of surgery. The patient was a 57-year-old man with sigmoid colon cancer of sufficient size to block the passage of the endoscope. The cancer was found to be widely infiltrated and adherent to the peritoneum over the bladder, with effusion around the tumor that made peritoneal disseminated metastasis a strong possibility. Moreover, many regional and periaortic lymph nodes were swollen. Sigmoid colon cancer at Stage IV was diagnosed. After preoperative chemotherapy [mFOLFOX6+bevacizumab (Bev)] was administered, tumor size decreased sufficiently to allow the endoscope to pass through. The effusion around the tumor disappeared, and lymph node swellings were reduced. The surgical findings revealed no evidence of peritoneal metastasis, and tumor adhesion to the peritoneum over the bladder was small, which limited the extent of combined peritonectomy. Ultimately, the histopathological diagnosis was Stage II,and histological evaluation of the drug therapy effects was that the tumor was then Grade 1b. Although clinical studies are currently conducted on preoperative chemotherapy for locally advanced colorectal cancer, preoperative chemotherapy is not established as standard treatment due to lack of clear evidence. The evaluation of the usefulness of preoperative chemotherapy is warrants future clinical studies.

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

    Q fever is a worldwide zoonosis caused by a fastidious bacterium, Coxiella burnetii. A recent major outbreak of which in the Netherlands will most likely lead to the emergence of hundreds of cases of C. burnetii endocarditis during the next decade. Patients undergoing cardiac valve surgery may carry undiagnosed Q fever endocarditis with possible disastrous outcomes, and hence may benefit from a screening strategy. The study aim was to evaluate the frequency of unsuspected latent Q fever endocarditis in patients undergoing routine valve surgery. At the present authors' institution, all resected cardiac valves/prostheses are examined routinely histologically, microbiologically and on a molecular biological basis, in addition to serological testing for fastidious microorganisms. A retrospective review was conducted of data relating to all patients who had unsuspected Q fever endocarditis that had been diagnosed after routine valve/prosthesis replacement/repair between 2000 and 2013 at the authors' institution. Among 6,401 patients undergoing valve surgery, postoperative examinations of the explanted valves/prostheses led to an unexpected diagnosis of Q fever endocarditis in 14 cases (0.2%), who subsequently underwent appropriate medical treatments. Only two of the patients (14%) had intraoperative findings suggestive of endocarditis. On serological analysis of the blood samples, 11 patients (79%) presented an evocative Phase I IgG antibody titer > or =800. Valvular tissue-sample analyses yielded positive cultures and PCR in the same 13 patients (93%), whereas pathological and immunohistochemical examinations alone were suggestive of endocarditis in only seven Cases (50%). This screening strategy led to an unexpected diagnosis of Q fever endocarditis in 0.2% of patients undergoing routine valve surgery, who received subsequent appropriate antibiotic therapy. Systematic serological analysis should be mandatory before performing heart valve surgery in countries where C

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

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

    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.

    The main causes of death in patients undergoing dialysis are cardiovascular diseases. Their presence is related to the nutritional status of patients treated with peritoneal dialysis, and has a predicted value in this kind of patient. Long-term therapy entails unfavourable changes, from which a clinically significant complication is protein-energy malnutrition and intensification of inflammatory processes. The aim of the study was to assess the nutritional status of patients with chronic kidney disease treated with peritoneal dialysis based on anthropometric, biochemical parameters analysis, a survey, as well as the determination of changes in measured parameters occurring over time. The study involved 40 people undergoing peritoneal dialysis (PD) and 30 healthy people. For dialyzed patients testing material was collected twice, every 6 months. Proteins, albumins, prealbumins, C-reactive protein and glucose levels were measured. Anthropometric measurements included body height, body weight, triceps skinfold and subscapular skinfold thickness. Body mass index (BMI) value and exponent of tissue protein source were calculated. The examined patients completed the questionnaire, which included, among other factors, the daily intake of nutrients, and lifestyle information. During the 6 month observation of the PD group a stastically significant increase in the energy value of intake food and amount of calories intake from carbohydrates was found. Analysis of nutritional status dependent on the BMI showed that overweight and obese patients are characterized by higher concentrations of the C-reactive protein and glucose, as well as lower concentrations of prealbumin compared to patients with normal body weight. At the same time, the energy value of food and the amount of protein in the group with BMI > 25 were smaller than in the other groups. During the 6 month observation a decrease the concentration of prealbumin and an increase in C-reactive protein in BMI > 25 group

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

    Oral health care in patients undergoing chemotherapy and/or radiation therapy can be complex. 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

    There is substantial variability in the perioperative administration of aspirin in patients undergoing noncardiac surgery, both among patients who are already on an aspirin regimen and among those who are not. Using a 2-by-2 factorial trial design, we randomly assigned 10,010 patients who were preparing to undergo noncardiac surgery and were at risk for vascular complications to receive aspirin or placebo and clonidine or placebo. The results of the aspirin trial are reported here. The patients were stratified according to whether they had not been taking aspirin before the study (initiation stratum, with 5628 patients) or they were already on an aspirin regimen (continuation stratum, with 4382 patients). Patients started taking aspirin (at a dose of 200 mg) or placebo just before surgery and continued it daily (at a dose of 100 mg) for 30 days in the initiation stratum and for 7 days in the continuation stratum, after which patients resumed their regular aspirin regimen. The primary outcome was a composite of death or nonfatal myocardial infarction at 30 days. The primary outcome occurred in 351 of 4998 patients (7.0%) in the aspirin group and in 355 of 5012 patients (7.1%) in the placebo group (hazard ratio in the aspirin group, 0.99; 95% confidence interval [CI], 0.86 to 1.15; P=0.92). Major bleeding was more common in the aspirin group than in the placebo group (230 patients [4.6%] vs. 188 patients [3.8%]; hazard ratio, 1.23; 95% CI, 1.01, to 1.49; P=0.04). The primary and secondary outcome results were similar in the two aspirin strata. Administration of aspirin before surgery and throughout the early postsurgical period had no significant effect on the rate of a composite of death or nonfatal myocardial infarction but increased the risk of major bleeding.

    Marked activation of the sympathetic nervous system occurs during and after noncardiac surgery. Low-dose clonidine, which blunts central sympathetic outflow, may prevent perioperative myocardial infarction and death without inducing hemodynamic instability. We performed a blinded, randomized trial with a 2-by-2 factorial design to allow separate evaluation of low-dose clonidine versus placebo and low-dose aspirin versus placebo in patients with, or at risk for, atherosclerotic disease who were undergoing noncardiac surgery. A total of 10,010 patients at 135 centers in 23 countries were enrolled. For the comparison of clonidine with placebo, patients were randomly assigned to receive clonidine (0.2 mg per day) or placebo just before surgery, with the study drug continued until 72 hours after surgery. The primary outcome was a composite of death or nonfatal myocardial infarction at 30 days. Clonidine, as compared with placebo, did not reduce the number of primary-outcome events (367 and 339, respectively; hazard ratio with clonidine, 1.08; 95% confidence interval [CI], 0.93 to 1.26; P=0.29). Myocardial infarction occurred in 329 patients (6.6%) assigned to clonidine and in 295 patients (5.9%) assigned to placebo (hazard ratio, 1.11; 95% CI, 0.95 to 1.30; P=0.18). Significantly more patients in the clonidine group than in the placebo group had clinically important hypotension (2385 patients [47.6%] vs. 1854 patients [37.1%]; hazard ratio 1.32; 95% CI, 1.24 to 1.40; P<0.001). Clonidine, as compared with placebo, was associated with an increased rate of nonfatal cardiac arrest (0.3% [16 patients] vs. 0.1% [5 patients]; hazard ratio, 3.20; 95% CI, 1.17 to 8.73; P=0.02). Administration of low-dose clonidine in patients undergoing noncardiac surgery did not reduce the rate of the composite outcome of death or nonfatal myocardial infarction; it did, however, increase the risk of clinically important hypotension and nonfatal cardiac arrest.

    Previous studies have shown that patients diagnosed with some autoimmune (AI) diseases are at an increased risk of leukaemia but limited data are available on survival. We systematically analysed the risks (standardized incidence ratio, SIR) and survival (hazard ratio, HR) in nine types of leukaemia among 402 462 patients hospitalized for any of 33 AI diseases and compared to persons not hospitalized for AI diseases. Risk for all leukaemia was increased after 13 AI diseases and survival was decreased after six AI diseases. SIRs were increased after all AI diseases for seven types of leukaemia, including SIR 1·69 (95% confidence interval (CI): 1·29-2·19) for acute lymphoblastic leukaemia (ALL), 1·85 (95% CI: 1·65-2·07) for acute myeloid leukaemia, 1·68 (95% CI: 1·37-2·04) for chronic myeloid leukaemia, 2·20 (95% CI: 1·69-2·81) for 'other myeloid leukaemia', 2·45 (95% 1·99-2·98) for 'other and unspecified leukaemia', 1·81 (95% CI: 1·11-2·81) for monocytic leukaemia, and 1·36 (95% CI: 1·08-1·69) for myelofibrosis. The HRs were increased for four types of leukaemia, most for myelofibrosis (1·74, 95% CI: 1·33-2·29) and ALL (1·42, 95% CI: 1·03-1·95). Some AI diseases, including rheumatoid arthritis, were associated with increased SIRs and HRs in many types of leukaemia. The present data showed increases in risk and decreases in survival for many types of leukaemia after various AI diseases. Leukaemia is a rare complication in AI disease but findings about this comorbidity at the time of leukaemia diagnosis may help to optimize the treatment and improve survival. © 2013 John Wiley & Sons Ltd.

    Introduction The neuroanaesthesia ensures stable perioperative cerebral haemodynamics, avoids sudden rise in intracranial pressure and prevents acute brain swelling. The clinical characteristics of dexmeditomidine make this intravenous agent a potentially attractive adjunct for neuroanaesthesia and in the neurological intensive care unit. Aim This study aimed to assess the effect of dexmedetomidine on intraoperative haemodynamic stability and to assess the intraoperative requirements of analgesic and other anaesthetic agents, and also to assess postoperative sedation, respiratory depression and any other side effects of dexmedetomidine as compared to placebo. Materials and Methods This prospective randomized study was done in 60 patients of either sex, age between 18 to 60 years and American Society of Anaesthesiologist (ASA) Grade I and II undergoing elective craniotomies under General Anaesthesia (GA) for intracranial Space Occupying Lesion (SOL). These 60 patients underwent thorough history, clinical examination and laboratory investigations. They were randomly divided into two groups, Group D (received Inj. Dexmedetomidine) and Group P (received Inj. Placebo). During bolus and infusion Heart Rate (HR), Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), Mean Arterial Pressure (MAP), Peripheral oxygen saturation (SPO2) was recorded at every five minutes interval for first 20 minute. Results The mean age in Group D was 39.5 years and in Group P was 40 years. The sex distribution in two groups was in Group D, 12 patients (40%) were females and 18 (60%) patients were males. While in Group P 10 (33.3%) were females and 20 (66.7%) patients were males. The two groups were comparable with respect to diagnosis and type of surgery of patients and difference was not statistically significant. The mean HR, the mean DBP and the mean MAP was lower in Group D as compared to Group P and the difference was statistically significant. Conclusion Dexmedetomidine

    The techniques, drugs and depth of sedation for flexible fiberoptic bronchoscopy is controversial, and several reports consider that the routine use of sedation is not a prerequisite. We evaluate whether the addition of sedation with propofol improves patient tolerance, compared to local anesthesic of the airway only. Eighteen patients with pneumonia undergoing flexible fiberoptic bronchoscopy were included in a randomized, single blind, prospective controlled study. The non-sedation group received airway topical anesthesia, whereas the sedation group received topical anesthesia and intravenous sedation with propofol. The degree of pain, cough, sensation of asphyxiation, degree of amnesia, global tolerance and acceptance of another bronchoscopy in the future were noted. Changes in blood pressure, heart rate and saturation of oxygen by pulse oximetry were also evaluated. The patients in sedation group had less cough (P < 0.05), pain (P < 0.01) and sensation of asphyxiation (P < 0.001). Global tolerance to the procedure was significantly better in the group under sedation (P < 0.01). These patients had total amnesia to the procedure (P < 0.0001), thus is more probable that will accept another bronchoscopy in the future (P < 0.01). There was a significant rise in heart rate and blood pressure in the patients without sedation. There were no differences in oxygen saturation (P = 0.75). Our results show that if we administer propofol for sedation, in addition to local anesthesia of the airway, the tolerance to the procedure is much better. Also it appears that sedation with propofol is safe if we carefully select and monitor the patient.

    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. To review the occurrence and recognition of uneventful intestinal malrotation discovered during regular cases of bariatric surgeries. 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. 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. 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.

    Neuroblastoma is the most common extracranial solid tumor in childhood. The vast majority of metastatic (M) stage patients present with disseminated tumor cells (DTCs) in the bone marrow (BM) at diagnosis and relapse. Although these cells represent a major obstacle in the treatment of neuroblastoma patients, insights into their expression profile remained elusive. The present RNA-Seq study of stage 4/M primary tumors, enriched BM-derived diagnostic and relapse DTCs, as well as the corresponding BM-derived mononuclear cells (MNCs) from 53 patients revealed 322 differentially expressed genes in DTCs as compared to the tumors (q < 0.001, |log2 FC|>2). Particularly, the levels of transcripts encoded by mitochondrial DNA were elevated in DTCs, whereas, for example, genes involved in angiogenesis were downregulated. Furthermore, 224 genes were highly expressed in DTCs and only slightly, if at all, in MNCs (q < 8 × 10(-75) log2 FC > 6). Interestingly, we found the transcriptome of relapse DTCs largely resembling those of diagnostic DTCs with only 113 differentially expressed genes under relaxed cut-offs (q < 0.01, |log2 FC|>0.5). Notably, relapse DTCs showed a positional enrichment of 31 downregulated genes on chromosome 19, including five tumor suppressor genes: SIRT6, BBC3/PUMA, STK11, CADM4 and GLTSCR2. This first RNA-Seq analysis of neuroblastoma DTCs revealed their unique expression profile in comparison to the tumors and MNCs, and less pronounced differences between diagnostic and relapse DTCs. The latter preferentially affected downregulation of genes encoded by chromosome 19. As these alterations might be associated with treatment failure and disease relapse, further functional studies on DTCs should be considered. © 2017 The Authors International Journal of Cancer published by John Wiley & Sons Ltd on behalf of UICC.

    In patients with atrial fibrillation (AF) undergoing coronary stent implantation, the optimal antithrombotic strategy is unclear. We evaluated whether use of oral anticoagulation (OAC) was associated with any benefit in morbidity or mortality in patients with AF, high risk of thromboembolism (TE) (CHA2DS2-VASC score ≥ 2) and coronary stent implantation. Among 8,962 unselected patients with AF seen between 2000 and 2010, a total of 2,709 (30%) had coronary artery disease and 417/2,709 (15%) underwent stent implantation while having CHA2DS2-VASC score ≥ 2. During follow-up (median=650 days), all TE, bleeding episodes, and major adverse cardiac events (i.e. death, acute myocardial infarction, target lesion revascularisation) were recorded. At discharge, 97/417 patients (23%) received OAC, which was more likely to be prescribed in patients with permanent AF and in those treated for elective stent implantation. The incidence of outcome event rates was not significantly different in patients treated and those not treated with OAC. However, in multivariate analysis, the lack of OAC at discharge was independently associated with increased risk of death/stroke/systemic TE (relative risk [RR] =2.18, 95% confidence interval [CI] 1.02-4.67, p=0.04), with older age (RR =1.12, 1.04-1.20, p=0.003), heart failure (RR =3.26, 1.18-9.01, p=0.02), and history of stroke (RR =18.87, 3.11-111.11, p=0.001). In conclusion, in patients with AF and high thromboembolic risk after stent implantation, use of OAC was independently associated with decreased risk of subsequent death/stroke/systemic TE, suggesting that OAC should be systematically used in this patient population.

    Background Anticoagulation after coronary stenting is essential to prevent stent thrombosis. Drug-eluting stents, which are the preferred therapy, may be associated with a higher tendency for stent thrombosis. Methods Patients who underwent coronary stent placement and presented with late stent thrombosis are described. Results Eight patients with stent thrombosis are presented. Early discontinuation of the antithrombotic medication is associated with the occurrence of these complications. Conclusion Long-term antithrombotic therapy seems essential to prevent stent thrombosis, especially for patients treated with drug-eluting stents. PMID:25696663

    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

    Lower respiratory tract infections in mechanically ventilated patients are a frequent cause of antibiotic treatment in intensive-care units. These infections present as severe sepsis or septic shock with respiratory dysfunction in intubated patients. Purulent respiratory secretions are needed for diagnosis, but distinguishing between pneumonia and tracheobronchitis is not easy. Both presentations are associated with longlasting mechanical ventilation and extended intensive-care unit stay, providing a rationale for antibiotic treatment initiation. Differentiation of colonisers from true pathogens is difficult, and microbiological data show Staphylococcus aureus and Pseudomonas aeruginosa to be of great concern because of clinical outcomes and therapeutic challenges. Key management issues include identification of the pathogen, choice of initial empirical antibiotic, and decisions with regard to the resolution pattern.

    BACKGROUND Although, there have been extensive research on the motivations driving patient to undergo cosmetic procedures, there is still a big question mark on the persuasive factors which may lead individuals to undergo cosmetic surgery. The present study evaluated various factors affecting patients undergoing cosmetic surgery in Bushehr, Southern Iran. METHODS From 24th March 2011 to 24th March 2012, eighty-one women and 20 men who wished to be operated in Fatemeh Zahra Hospital in Bushehr, Southern Iran and Pars Clinic, Iran were enrolled by a simple random sampling method. They all completed a questionnaire to consider reasons for cosmetic procedures. The collected data were statistically analyzed. RESULTS Demographical, sociological and psychological factors such as age, gender, educational level, marital status, media, perceived risks, output quality, depression and self-improvement were determined as factors affecting tendency of individuals to undergo cosmetic surgery in this region. Trend to undergo cosmetic surgery was more prevalent in educational below bachelor degree, married subjects, women population of 30-45 years age group. Education level, age, marital status and gender were respectively the influential factors in deciding to undergo cosmetic surgery. Among the socio-psychological factors, self-improvement, finding a better job opportunity, rivalry, media, health status as well as depression were the most persuasive factors to encourage people to undergo cosmetic surgery too. Cost risk was not important for our samples in decision making to undergo cosmetic surgery. CONCLUSION We need to fully understand the way in which the combination of demographic, social and psychological factors influence decision-making to undergo cosmetic surgery. PMID:25734051

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

    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.

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

    A recent international consensus conference on the reduction in mortality in cardiac anesthesia and intensive care included intraoperative aortic balloon pump among the ancillary (i.e. non-surgical) drugs/techniques/strategies that might influence survival rates in patients undergoing cardiac surgery. The consensus conferences state that "Pre-operative intraoperative aortic balloon pump might reduce 30-day mortality in elective high risk patients undergoing coronary artery bypass surgery unless specifically contraindicated". The authors of this "expert opinion" presents their insights into the use of the preoperative intraoperative aortic balloon pump and conclude that based on available limited randomized controlled trials and clinical experience preoperative intraoperative aortic balloon pump saves lives in unstable patients.

    To evaluate predictors of allogenic blood transfusion requirements in patients undergoing minimal invasive oesophagectomy at a tertiary high volume centre for oesophago-gastric surgery. Retrospective analysis of all patients undergoing minimal access oesophagectomy in our department between January 2010 and December 2011. Patients were divided into two groups depending on whether they required a blood transfusion at any time during their index admission. Factors that have been shown to influence perioperative blood transfusion requirements in major surgery were included in the analysis. Binary logistic regression analysis was performed to determine the impact of patient and perioperative characteristics on transfusion requirements during the index admission. A total of 80 patients underwent minimal access oesophagectomy, of which 61 patients had a laparoscopic assisted oesophagectomy and 19 patients had a minimal invasive oesophagectomy. Perioperative blood transfusion was required in 28 patients at any time during hospital admission. On binary logistic regression analysis, a lower preoperative haemoglobin concentration (p < 0.01), suffering a significant complication (p < 0.005) and laparoscopic assisted oesophagectomy (p < 0.05) were independent predictors of blood transfusion requirements. It has been reported that requirement for blood transfusion can affect long-term outcomes in oesophageal cancer resection. Two factors which could be addressed preoperatively; haemoglobin concentration and type of oesophageal resection, may be valuable in predicting blood transfusions in patients undergoing minimally invasive oesophagectomy. Our analysis revealed that preoperative haemoglobin concentration, occurrence of significant complications and type of minimal access oesophagectomy predicted blood transfusion requirements in the patient population examined.

    Spinal anesthesia is increasingly viewed as a reasonable alternative to general anesthesia for lumbar spine surgery. However, the results of spinal anesthesia in elderly patients undergoing lumbar spine decompression and combined decompression and fusion procedures are limited in the literature. The aim of this study was to report a single institution's experience using spinal anesthesia in elderly patients undergoing lumbar spine surgery. A retrospective review was conducted using a prospectively collected database of consecutive lumbar spine surgeries performed under spinal anesthesia in patients 70 years or older at a single center between December 2013 and October 2015. A total of 56 patients were included in the study; 27 patients (48%) underwent lumbar decompression and 29 patients (52%) underwent combined decompression and fusion procedures. Mean operative time was 101 minutes (range, 30-210 minutes), and mean operative blood loss was 187 mL (range, 20-700 mL). Mean maximum inpatient postoperative visual analog scale score was 6.2 (range, 1-10). Nausea occurred in 21% (12 of 56) of the patients. Mean length of stay was 2.4 days (range, 1-6 days). No mortality, stroke, permanent loss of function, or pulmonary embolism occurred. None of the cases required conversion to general anesthesia. All of the patients were ambulatory on either the day of the surgery or the next morning. These results demonstrate that spinal anesthesia is a viable method of anesthesia for patients 70 years and older undergoing lumbar spine surgery. They also demonstrate the safety of this method for patients older than 84 years and for surgeries lasting up to 3½ hours. [Orthopedics. 2017; 40(2):e317-e322.].

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

    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.

    Sedation plays a central role in making colonoscopy tolerable for patients and feasible for the endoscopist to perform. The array of agents used for endoscopic sedation continues to evolve. Fospropofol (FP), a prodrug of propofol with a slower pharmacokinetic profile, is currently under evaluation for use during endoscopic procedures. Preliminary data suggests that FP dosed at 6.5 mg/kg is well tolerated by most patients with perineal paresthesias being the most commonly experienced adverse effect. This article will examine the current literature on the use of FP for the sedation of patients undergoing colonoscopy, highlighting the pharmacokinetics, pharmacodynamics, risks, and common adverse events associated with the novel sedative/hypnotic.

    Hemolysis is a common complication of extracorporeal membrane oxygenation (ECMO) support and is associated with increased mortality. Frequent monitoring of markers of hemolysis is performed at ECMO centers. We report two cases of spurious hemolysis caused by hypertriglyceridemia in patients undergoing ECMO support. Critically ill patients, including those receiving ECMO, may be at risk of developing medication-induced hypertriglyceridemia. The interference of lipids with the measurement of plasma free hemoglobin, a marker of hemolysis, should be recognized. Our cases highlight the importance of investigating hypertriglyceridemia as part of the assessment of unexplained hemolysis in patients supported with ECMO.

  5. Oral anticoagulant therapy in patients undergoing dental surgery.

    The literature on dental surgery in patients receiving oral anticoagulants is reviewed, and methods of managing anticoagulant therapy to minimize the risk of complications are discussed. Although blood loss during and after oral surgery in patients receiving oral anticoagulant drugs can be substantial, research indicates that most bleeding incidents are not serious and can be controlled by local measures. Studies of 241 anticoagulant-treated patients undergoing more than 500 dental extractions during the 1950s and 1960s showed that only 9 had postoperative bleeding. More recent studies indicate that continued anticoagulation can increase the frequency of prolonged bleeding and delay wound healing. An antifibrinolytic mouthwash containing tranexamic acid can effectively suppress postoperative bleeding. Gelatin sponges, oxidized cellulose, and microcrystalline collagen are other useful hemostatic agents. A reduction in the intensity of anticoagulation therapy has been recommended; the prothrombin time should be measured shortly before the procedure in such patients. In many patients the duration of subtherapeutic anticoagulation must be minimized to reduce the possibility of thromboembolism. An option for high-risk patients is to switch them to heparin. Each patient must be evaluated individually, and the level of risk of the dental procedure and the risk of thromboembolism should be taken into account. In patients taking oral anticoagulants who must undergo dental surgery, careful control of the intensity of anticoagulation and improved methods of local hemostasis can minimize the risk of hemorrhagic complications and thromboembolism.

    Neopterin is a diagnostic or a prognostic biomarker for several pathologies including renal diseases. However, the association between neopterin status and causative main reasons such as diabetes and hypertension for renal disease remains unclear. The aim of the study was to evaluate neopterin levels in diabetes and hypertension patients treated with/without hemodialysis. According to primary renal disorders, the patients undergoing hemodialysis were classified into 4 groups as diabetic nephropathy, hypertensive nephropathy, reflux nephropathy or interstitial nephritis, and others. The controls consisted of healthy subjects, hypertensive subjects, and diabetic individuals without any renal disorder. In the study, both urinary and serum neopterin levels were measured using high performance liquid chromatography and enzyme-linked immunosorbant assay in patients undergoing regular hemodialysis therapy (n=71). The effects of the duration of hemodialysis and treatment of erythropoietin and/or iron on neopterin levels were also evaluated. Neopterin levels were found to be higher in hemodialysis patients than in the healthy controls (P<0.05). A significant difference in neopterin levels was also found between diabetic control patients and diabetic nephropathy patients (P<0.05). A similar significant difference was detected in neopterin levels between hypertensive patients with/without nephropathy (P<0.05). Neopterin may be an early critical marker for progression of nephropathy in diabetic and hypertensive patients in early stages.

    The use of diagnostic medical imaging is becoming increasingly more commonplace in the pediatric setting. However, many medical imaging modalities expose pediatric patients to ionizing radiation, which has been shown to increase the risk of cancer development in later life. This review article provides a comprehensive overview of the available data regarding the risk of cancer development following exposure to ionizing radiation from diagnostic medical imaging. Attention is paid to modalities such as computed tomography scans and fluoroscopic procedures that can expose children to radiation doses orders of magnitude higher than standard diagnostic x-rays. Ongoing studies that seek to more precisely determine the relationship of diagnostic medical radiation in children and subsequent cancer development are discussed, as well as modern strategies to better quantify this risk. Finally, as cardiovascular imaging and intervention contribute substantially to medical radiation exposure, we discuss strategies to enhance radiation safety in these areas.

    Little information is available regarding the rate of prosthetic joint infections (PJIs) in patients undergoing carpal tunnel release (CTR) without antibiotic prophylaxis. Hand surgeons should be aware of patients' history of arthroplasty. All patients who underwent CTR at our institution between 2012 and 2014 were identified and their charts were reviewed to identify those who had a history of total hip, knee, and/or shoulder arthroplasty. Further chart review consisted of identifying a history of PJI, use of perioperative antibiotics, and surgeon awareness of prior arthroplasty. Two hundred seventy-five CTR surgeries were performed in patients who had previously undergone total joint arthroplasty (TJA). There were no PJIs in any group of patients (P = 0.01). Hand surgeon awareness of the presence of an arthroplasty history had no discernable effect on the choice to use antibiotics. There was a 0% rate of PJI in our series of patients with a history of TJA who underwent CTR. Overall hand surgeon awareness of TJA status was poor or poorly documented. Routine prophylactic antibiotics may not be indicated in patients undergoing CTR, even with the presence of a prosthetic joint. IV.

    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.

    Objectives Body image is a critical issue for cancer patients undergoing reconstructive surgery, as they can experience disfigurement and functional impairment. Distress related to appearance changes can lead to various psychosocial difficulties, and patients are often reluctant to discuss these issues with their healthcare team. Our goals were to design and evaluate a screening tool to aid providers in identifying patients who may benefit from referral for specialized psychosocial care to treat body image concerns. Methods We designed a brief 4-item instrument and administered it at a single time point to cancer patients who were undergoing reconstructive treatment. We used simple and multinomial regression models to evaluate whether survey responses, demographic, or clinical variables predicted interest and enrollment in counseling. Results Over 95% of the sample (n = 248) endorsed some concerns, preoccupation, or avoidance due to appearance changes. Approximately one-third of patients were interested in obtaining counseling or additional information to assist with body image distress. Each survey item significantly predicted interest and enrollment in counseling. Concern about future appearance changes was the single best predictor of counseling enrollment. Sex, age, and cancer type were not predictive of counseling interest or enrollment. Conclusions We present initial data supporting use of the Body Image Screener for Cancer Reconstruction. Our findings suggest benefits of administering this tool to patients presenting for reconstructive surgery. It is argued that screening and treatment for body image distress should be provided to this patient population at the earliest possible time point. PMID:25066586

  11. The role of eptifibatide in patients undergoing percutaneous coronary intervention.

    PubMed

    2007-06-01

    Glycoprotein (GP) IIb/IIIa receptor antagonists inhibit the binding of ligands to activated platelet GP IIb/IIIa receptors and, therefore, prevent the formation of platelet thrombi. They have been extensively studied in patients undergoing percutaneous coronary intervention (PCI). Eptifibatide, one of the approved GP IIb/IIIa inhibitors, is a small heptapeptide that is highly selective and rapidly dissociates from its receptor after cessation of therapy. In clinical studies, concomitant administration of eptifibatide in patients undergoing elective PCI reduced thrombotic complications in the IMPACT-II (Integrilin to Minimize Platelet Aggregation and Prevent Coronary Thrombosis II) and ESPRIT (Enhanced Suppression of the Platelet IIb/IIIa Receptor with Integrilin Therapy) trials. In the PURSUIT (Platelet Glycoprotein IIb/IIIa in Unstable Angina: Receptor Suppression Using Integrilin Therapy) trial, which included 10,948 patients with non-ST-elevation acute coronary syndromes, eptifibatide significantly reduced the primary end point of death and non-fatal myocardial infarction at 30 days compared with placebo. In patients with ST-segment elevation myocardial infarction (STEMI), eptifibatide has been studied as adjunct to primary PCI and improved epicardial flow and tissue reperfusion. Studies are now evaluating eptifibatide in high-risk patients with non-ST elevation acute coronary syndromes (NSTE-ACS) and a planned early invasive strategy in the EARLY-ACS (Eptifibatide Administration prior to Diagnostic Catherization and Revascularization to Limit Myocardial Necrosis in Acute Coronary Syndrome) trial and in patients with primary PCI for STEMI in comparison to abciximab in the EVA-AMI (Eptifibatide versus Abciximab in Primary PCI for Acute Myocardial Infarction) trial. After the completion of these trials, the value of etifibatide in patients undergoing PCI in different indications can be determined.

    Anesthesia and surgery interfere with normal thermoregulation, and nearly all patients will become hypothermic unless compensatory measures are used. Preoperative patient warming and intraoperative methods using forced air and warmed intravenous fluids are important methods for maintaining patient's core temperature during the perioperative period. The benefits of maintaining normothermia include reductions in postoperative wound infection, the risk of perioperative coagulopathy, and myocardial ischemia. These advantages, demonstrated in patients undergoing general surgery, would be expected in patients undergoing gynecological surgery but have not been specifically studied in that population. Few studies have examined the maternal and neonatal effects of hypothermia after cesarean delivery. The results conflict as to the effectiveness of maternal warming techniques used to prevent it and the effects on neonatal temperature and acid-base status at delivery. Large prospective studies will be required to show significant effects on rates of maternal wound infection after cesarean delivery. European and American national obstetrical organizations have not published recommendations regarding the perioperative thermal regulation for cesarean delivery. We review the physiology of thermal regulation and perioperative thermal management in surgical patients and the literature that has examined perioperative maternal warming for cesarean delivery.

    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.

    BACKGROUND Routine preoperative testing is not recommended for patients undergoing cataract surgery, because testing neither decreases adverse events nor improves outcomes. We sought to assess adherence to this guideline, estimate expenditures from potentially unnecessary testing, and identify patient and health care system characteristics associated with potentially unnecessary testing. METHODS Using an observational cohort of Medicare beneficiaries undergoing cataract surgery in 2011, we determined the prevalence and cost of preoperative testing in the month before surgery. We compared the prevalence of preoperative testing and office visits with the mean percentage of beneficiaries who underwent tests and had office visits during the preceding 11 months. Using multivariate hierarchical analyses, we examined the relationship between preoperative testing and characteristics of patients, health system characteristics, surgical setting, care team, and occurrence of a preoperative office visit. RESULTS Of 440,857 patients, 53% had at least one preoperative test in the month before surgery. Expenditures on testing during that month were $4.8 million higher and expenditures on office visits $12.4 million higher (42% and 78% higher, respectively) than the mean monthly expenditures during the preceding 11 months. Testing varied widely among ophthalmologists; 36% of ophthalmologists ordered preoperative tests for more than 75% of their patients. A patient’s probability of undergoing testing was associated mainly with the ophthalmologist who managed the preoperative evaluation. CONCLUSIONS Preoperative testing before cataract surgery occurred frequently and was more strongly associated with provider practice patterns than with patient characteristics.

    The objective of this observational study was to compare 48-h all-cause mortality (as well as hospital stay mortality) among critically ill patients who underwent echocardiography either with or without an ultrasound contrast agent (UCA). The safety of perflutren-based UCAs has been questioned by the U.S. Food and Drug Administration (particularly when administered to critically ill patients) following rare reports of deaths or life-threatening adverse reactions that occurred in close temporal relationship to UCA administration. This was a retrospective observational outcome study conducted in critically ill patients to compare all-cause 48-h and hospital stay mortality subsequent to echocardiography procedures performed either with or without a UCA. The study utilized discharge data from a database maintained by Premier, Inc. (Charlotte, North Carolina). Premier's database is the largest U.S. hospital-based, service-level comparative database for quality and outcomes research, and provides detailed resource utilization data along with patients' primary and secondary diagnoses and procedure billing codes. A propensity score-matching algorithm between UCA-enhanced echocardiography patients and non-contrast-enhanced echocardiography patients was utilized to reduce the potential for imbalance in covariates of selected patients in the comparison of mortality between groups. Patients undergoing echocardiography with a UCA had lower mortality at 48 h compared with patients undergoing non-contrast-enhanced echocardiography (1.70% vs. 2.50%), with an odds ratio = 0.66 (95% confidence interval [CI]: 0.54 to 0.80). Patients undergoing echocardiography with a UCA had lower hospital stay mortality compared with patients undergoing noncontrast echocardiography (14.85% vs. 15.66%), with an odds ratio = 0.89 (95% CI: 0.84 to 0.96). In critically ill, propensity-matched hospitalized patients undergoing echocardiography, use of a UCA is associated with a 28% lower mortality at

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

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

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

    Obesity constitutes a clear risk factor for cholelithiasis, especially if it is associated with a rapid weight loss, as is the case of patients following bariatric surgery. Prophylactic cholecystectomy is indicated in biliopancreatic diversions due to the high incidence of postoperative cholelithiasis. However, there is no agreement on gastric bypass. This study was conducted to establish the incidence of cholecystopathy demonstrated by histology and to assess the indication for prophylactic cholecystectomy in a systematic way on patients undergoing gastric bypass. The evaluation is based on 100 consecutive morbidly obese patients undergoing open gastric bypass surgery with concomitant prophylactic cholecystectomy. Variables studied were: age, gender, body mass index, preoperative ultrasound and the anatomopathologic analysis of the gallbladder that was removed. Of the 100 patients who took part in the trial, 11 had had a previous cholecystectomy. Among the 89 patients remaining, preoperative ultrasound diagnosis of cholelithiasis was 16.8%, and the actual postoperative incidence was 24.7%. Other histologic alterations were: cholesterolosis 46.1%, chronic unspecified cholecystitis 22.5%, and granulomatous cholecystitis 1.1%. The total incidence of cholecystopathy was 93.3%. The morbi-mortality related to cholecystectomy was 0%. Based on these results and given the absence of morbidity, we believe that prophylactic cholecystectomy is suitable during open gastric bypass.

    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.

    Physiotherapy is considered an important component of the perioperative period of lung resection surgery. A systematic review was conducted to assess evidence for the effectiveness of different physiotherapy interventions in patients undergoing lung cancer resection surgery. Online literature databases [Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, SCOPUS, PEDro and CINAHL] were searched up until June 2013. Studies were included if they were randomized controlled trials, compared 2 or more perioperative physiotherapy interventions or compared one intervention with no intervention, included only patients undergoing pulmonary resection for lung cancer and assessed at least 2 or more of the following variables: functional capacity parameters, postoperative pulmonary complications or length of hospital stay. Reviews and meta-analyses were excluded. Eight studies were selected for inclusion in this review. They included a total of 599 patients. Seven of the studies were identified as having a low risk of bias. Two studies assessed preoperative interventions, 4 postoperative interventions and the remaining 2 investigated the efficacy of interventions that were started preoperatively and then continued after surgery. The substantial heterogeneity in the interventions across the studies meant that it was not possible to conduct a meta-analysis. The most important finding of this systematic review is that presurgical interventions based on moderate-intense aerobic exercise in patients undergoing lung resection for lung cancer improve functional capacity and reduce postoperative morbidity, whereas interventions performed only during the postoperative period do not seem to reduce postoperative pulmonary complications or length of hospital stay. Nevertheless, no firm conclusions can be drawn because of the heterogeneity of the studies included.

    Earlier studies suggest that administering statins prior to percutaneous coronary interventions (PCIs) is associated with lower risk of periprocedural myocardial infarction and contrast-induced nephropathy. Current American College of Cardiology/American Heart Association guidelines recommend routine use of statins prior to PCI. It is unclear how commonly this recommendation is followed in clinical practice and what its effect on outcomes is. We evaluated the incidence and in-hospital outcomes associated with statin pretreatment among patients undergoing PCI and enrolled in the Blue Cross Blue Shield of Michigan Cardiovascular Consortium PCI registry at 44 hospitals in Michigan between January 2010 and December 2012. Propensity and exact matching were used to adjust for the nonrandom use of statins prior to PCI. Long-term mortality was assessed in a subset of patients who were linked to Medicare data. Our study population was comprised of 80,493 patients of whom 26,547 (33 %) did not receive statins prior to undergoing PCI. When compared to statin receivers, nonreceivers had lower rates of prior cardiovascular disease. In the matched analysis, absence of statin use prior to PCI was associated with a similar rate of in-hospital mortality (0.43% vs 0.42%, odds ratio 1.00, 95% CI 0.70-1.42, P = .98) and periprocedural myocardial infarction (2.34% vs 2.10%, odds ratio 1.13, 95% CI 0.97-1.32, P = .11) compared to statin receivers. Likewise, no difference in the rate of coronary artery bypass grafting, cerebrovascular accident (CVA), or contrast-induced nephropathy was observed. There was no association between pre-PCI use of statins and long-term survival among the subset of included Medicare patients (hazard ratio = 1.0, P = .96). A significant number of patients undergo PCI without statin pretreatment, but this is not associated with in-hospital major complications or long-term mortality. Copyright © 2014 Mosby, Inc.

    Dilated cardiomyopathy (DCM) is the most frequent cause of heart transplantation (HTx). The genetic basis of DCM among patients undergoing HTx has been poorly characterized. We sought to determine the genetic basis of familial DCM HTx and to establish the yield of modern next generation sequencing (NGS) technologies in this setting. Fifty-two heart-transplanted patients due to familial DCM underwent NGS genetic evaluation with a panel of 126 genes related to cardiac conditions (59 associated with DCM). Genetic variants were initially classified as pathogenic mutations or as variants of uncertain significance (VUS). Final pathogenicity status was determined by familial cosegregation studies. Initially, 24 pathogenic mutations were found in 21 patients (40%); 25 patients (48%) carried 19 VUS and 6 (12%) did not show any genetic variant. Familial evaluation of 220 relatives from 36 of the 46 families with genetic variants confirmed pathogenicity in 14 patients and allowed reclassification of VUS as pathogenic in 17 patients, and as non-pathogenic in 3 cases. At the end of the study, the DCM-causing mutation was identified in 38 patients (73%) and 5 patients (10%) harbored only VUS. No genetic variants were identified in 9 cases (17%). The genetic spectrum of familial DCM patients undergoing HTx is heterogeneous and involves multiple genes. NGS technology plus detailed familial studies allow identification of causative mutations in the vast majority of familial DCM cases. Detailed familial studies remain critical to determine the pathogenicity of underlying genetic defects in a substantial number of cases.

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

    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.

    The objective of present study was to classify oral mucositis according to the Common Toxicity Criterion (CTC) international parameters in head and neck tumor patients simultaneously treated with radio and chemotherapy, and characterize a patient profile in our area, observing the individuals' habits, tumor characteristics, treatment protocol and acute reaction intensity. Fifty patients undergoing simultaneous 66 to 70 Gy megavoltage radiotherapy and cisplatin/carboplatin chemotherapy were evaluated in this study. Weekly evaluations of the degree of mucositis were perfoemed according to CTC, a four-degree ordinal scale; 36% of all patients and 100% of those with diabetes discontinued treatment due to mucositis, showing that this pathology contributes to the severity of mucositis.

    The benefit of long-term dual antiplatelet therapy (DAPT) in patients with acute coronary syndromes, drug-eluting stents and those at high risk for thromboembolic events has been well established in a number of well-designed randomized controlled studies. Current research in this area has focused on the development of novel antiplatelet agents for clinical use. The BRIDGE trial evaluated the use of cangrelor as a bridge to coronary artery bypass graft surgery in patients receiving extended DAPT. The BRIDGE trial results confirm the efficacy and safety of cangrelor in this population. This study is novel as it attempts to address the lapse in thienopyridine therapy required for many surgical and invasive procedures. The future of antiplatelet agents, particularly cangrelor, must also focus on bridging for high-risk patients undergoing noncoronary artery bypass graft surgical procedures. Overall, the BRIDGE trial represents a significant advance for patients appropriate for long-term DAPT.

    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.

    Although red blood cells (RBCs) transfusion is sometimes associated with adverse reactions, anemia could also lead to increased morbidity and mortality in high-risk patients. For these reasons, the definition of perioperative strategies that aims to detect and treat preoperative anemia, prevent excessive blood loss, and define "optimal" transfusion algorithms is crucial. Although the treatment with preoperative iron and erythropoietin has been recommended in some specific conditions, several controversies exist regarding the benefit-to-risk balance associated with these treatments. Further studies are needed to better define the indications, dosage, and route of administration for preoperative iron with or without erythropoietin supplementation. Although restrictive transfusion strategies in patients undergoing cardiac surgery have been shown to effectively reduce the incidence and the amount of RBCs transfusion without increase in side effects, some high-risk patients (e.g., symptomatic acute coronary syndrome) could benefit from higher hemoglobin concentrations. Despite all efforts made last decade, a significant amount of work remains to be done to improve hemoglobin optimization and transfusion strategies in patients undergoing cardiac surgery.

    A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was the impact of modified ultrafiltration on adult patients undergoing cardiac surgery in terms of inflammatory and metabolic changes, blood loss and early clinical outcomes. A total of 155 papers were identified using the search as described below. Of these, six papers presented the best evidence to answer the clinical question as they reported data to reach conclusions regarding the issues of interest for this review. The author, date and country of publication, patient group, study type and weaknesses and relevant outcomes were tabulated. Modified ultrafiltration in adult patients undergoing cardiac surgery seems to attenuate the levels of inflammatory molecules associated with surgery, reduces blood loss and blood transfusion and improves cardiac output, index and systemic vascular resistance. However, this was not translated in any reduction in length of stay in intensive care unit or hospital. Most studies were single-centre prospective non-blinded trials that included a small cohort of elective coronary artery bypass grafting patients, which makes it underpowered to provide unbiased evidence regarding clinical outcomes. Properly designed and conducted prospective randomized studies are required to answer whether the beneficial effect of modified ultrafiltration on systemic inflammatory molecules associated with surgery can translate with improvement in clinical outcome.

    Atrial fibrillation (AF) is the most common cardiac arrhythmia, occurring in 1-2% of overall population, involving more than 6 millions of European people. It is associated to a reduced quality of life and an increased morbidity and mortality. The Framingham study showed the link between angina and AF. The same risk factors, such as hypertension, diabetes and obesity promote both AF and coronary artery disease (CAD). About 1/4 of AF patients develop a CAD and, in this setting, about 1/5 undergoes a percutaneous coronary intervention (PCI). In patients with both AF and CAD, the optimal medical strategy is challenging and it is still debated in cardiological community, since patients treated by dual (two antiplatelets drugs ore one antiplatelets drug and an oral anticoagulant drug) or triple therapy (two antiplatelets drugs and an oral anticoagulant drug) are exposed to divergent risk of bleeding or thromboembolic and ischemic complications. Aim of this paper is to focus the attention on the different problems arising from the presence of AF in patients undergoing PCI, such as the risk of stroke, bleeding and stent thrombosis.

To assess the PPB rate and outcome and identify risk factors associated with PPB in patients taking clopidogrel. Single-center, retrospective study. Demographics, clinical parameters, polyp characteristics, polypectomy techniques, and postpolypectomy events in the groups were compared by univariate analysis. Stepwise logistic regression analyses identified independent risk factors associated with PPB. Veterans Affairs Medical Center. A total of 142 patients (375 polypectomies) taking clopidogrel (cases) and 1243 patients (3226 polypectomies) not taking clopidogrel (controls). None. Postpolypectomy bleeding, hospitalization, and mortality. The immediate (intraprocedural) bleeding rate was similar in the 2 groups (2.1% vs 2.1%). Delayed (postprocedural) PPB rate was higher in the group taking clopidogrel (3.5% vs 1.0%, P = .02). Delayed bleeding of significance requiring hospitalization and transfusion/intervention was also higher in patients taking clopidogrel (2.1% vs 0.4%, P = .04). The length of hospital stay and interventions for PPB were comparable between the 2 groups. There was no mortality. Concomitant use of clopidogrel and aspirin/other nonsteroidal anti-inflammatory drugs (odds ratio 3.7; 95% CI, 1.6-8.5) and the number of polyps removed (OR 1.3; 95% CI, 1.2-1.4) were the only significant risk factors associated with PPB. Clopidogrel alone was not an independent risk factor for PPB. Retrospective study and small number of patients with PPB. The PPB rate is significantly higher in patients undergoing polypectomy while taking clopidogrel and concomitant aspirin/nonsteroidal anti-inflammatory drugs; however, the risk is small and the outcome is favorable.

    Prospective evaluation of anxiety in patients undergoing computed tomography (CT) imaging using a standardized state-trait anxiety inventory (STAI-S) and identification of possible risk factors. During a 9-month interval, patients undergoing CT were questioned using STAI-S. Additionally, 10 questions concerning specific procedure-related features (claustrophobia, radiation, administration of contrast, and so forth) were added. Moreover, sex, age, admitting subspecialty, organ region, reason for imaging, and prior imaging studies were recorded. Statistical analysis was performed using the Student t test and linear regression analysis; significance level was set to 5%. Of 6122 patients, 825 patients undergoing CT (14%) were included (67% men; average age, 54 ± 17 years). Average STAI was 42 ± 10 with women (45 ± 11 vs. 41 ± 10; P < .001) and patients who received intravenous contrast (43 ± 10 vs. 42 ± 11; P = .021) showing significantly higher anxiety levels compared to those without contrast. Patients with investigations of their extremities (41 ± 11 vs. 43 ± 10; P = .020) and trauma patients (41 ± 11 vs. 43 ± 10; P = .006) revealed significantly lower STAI results. Patients who had never received a CT scan before showed significantly greater STAI-S values than those with repeat studies (42 ± 10 vs. 41 ± 11; P = .036). Females had greater fears concerning examination results (P < .001), radiation exposure (P = .032), administration of contrast (P = .014), and claustrophobia (P < .001). Patients with known malignancies had a significantly higher level of anxiety concerning their CT results (P = .002). Anxiety does not only occur before MRI but also occur before CT. Its sources are manifold and include communication of CT results, administration of contrast agents, radiation exposure, and claustrophobia. In this setting, women seemed to be more receptive than men. Copyright © 2015 AUR. Published by Elsevier Inc

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

    Background The “July effect” refers to the phenomenon of adverse impacts on patient care arising from the changeover in medical staff that takes place during this month at academic medical centres in North America. There has been some evidence supporting the presence of the July effect, including data from surgical specialties. Uniformity of care, regardless of time of year, is required for patients undergoing major cancer surgery. We therefore sought to perform a population-level assessment for the presence of a July effect in this field. Methods We used the Nationwide Inpatient Sample to abstract data on patients undergoing 1 of 8 major cancer surgeries at academic medical centres between Jan. 1, 1999, and Dec. 30, 2009. The primary outcomes examined were postoperative complications and in-hospital mortality. Univariate analyses and subsequently multivariate analyses, controlling for patient and hospital characteristics, were performed to identify whether the time of surgery was an independent predictor of outcome after major cancer surgery. Results On univariate analysis, the overall postoperative complication rate, as well as genitourinary and hematologic complications specifically, was higher in July than the rest of the year. However, on multivariate analysis, only hematologic complications were significantly higher in July, with no difference in overall postoperative complication rate or in-hospital mortality for all 8 surgeries considered separately or together. Conclusion On the whole, the data confirm an absence of a July effect in patients undergoing major cancer surgery. PMID:24666444

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

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

    Objective: To define the incidence of problematic common bile duct calculi in patients undergoing laparoscopic cholecystectomy. Summary Background Data: In patients selected for laparoscopic cholecystectomy, the true incidence of potentially problematic common bile duct calculi and their natural history has not been determined. We evaluated the incidence and early natural history of common bile duct calculi in all patients undergoing laparoscopic cholecystectomy with intraoperative and delayed postoperative cholangiography. Methods: Operative cholangiography was attempted in all patients. In those patients in whom a filling defect was noted in the bile duct, the fine bore cholangiogram catheter was left securely clipped in the cystic duct for repeated cholangiography at 48 hours and at approximately 6 weeks postoperatively. Results: Operative cholangiography was attempted in 997 consecutive patients and was accomplished in 962 patients (96%). Forty-six patients (4.6%) had at least one filling defect. Twelve of these had a normal cholangiogram at 48 hours (26% possible false-positive operative cholangiogram) and a further 12 at 6 weeks (26% spontaneous passage of calculi). Spontaneous passage was not determined by either the number or size of calculi or by the diameter of the bile duct. Only 22 patients (2.2% of total population) had persistent common bile duct calculi at 6 weeks after laparoscopic cholecystectomy and retrieved by endoscopic retrograde cholangiopancreatography. Conclusions: Choledocholithiasis occurs in 3.4% of patients undergoing laparoscopic cholecystectomy but more than one third of these pass the calculi spontaneously within 6 weeks of operation and may be spared endoscopic retrograde cholangiopancreatography. Treatment decisions based on assessment by operative cholangiography alone would result in unnecessary interventions in 50% of patients who had either false positive studies or subsequently passed the calculi. These data support a short

    Background Methicillin-resistant Staphylococcus aureus is a leading cause of death in patients undergoing hemodialysis. However, controversy exists about the optimal dose of vancomycin that will yield the recommended pre-hemodialysis serum concentration of 15–20 mg/L. Objective To develop a data-driven model to optimize the accuracy of maintenance dosing of vancomycin for patients undergoing hemodialysis. Methods A prospective observational cohort study was performed with 164 observations obtained from a convenience sample of 63 patients undergoing hemodialysis. All vancomycin doses were given on the floor after completion of a hemodialysis session. Multivariate linear generalized estimating equation analysis was used to examine independent predictors of pre-hemodialysis serum vancomycin concentration. Results Pre-hemodialysis serum vancomycin concentration was independently associated with maintenance dose (B = 0.658, p < 0.001), baseline pre-hemodialysis serum concentration of the drug (B = 0.492, p < 0.001), and interdialytic interval (B = −2.133, p < 0.001). According to the best of 4 models that were developed, the maintenance dose of vancomycin required to achieve a pre-hemodialysis serum concentration of 15–20 mg/L, if the baseline serum concentration of the drug was also 15–20 mg/L, was 5.9 mg/kg with interdialytic interval of 48 h and 7.1 mg/kg with interdialytic interval of 72 h. However, if the baseline pre-hemodialysis serum concentration was 10–14.99 mg/L, the required dose increased to 9.2 mg/kg with an interdialytic interval of 48 h and 10.0 mg/kg with an interdialytic interval of 72 h. Conclusions The maintenance dose of vancomycin varied according to baseline pre-hemodialysis serum concentration of the drug and interdialytic interval. The current practice of targeting a pre-hemodialysis concentration of 15–20 mg/L may be difficult to achieve for the majority of patients undergoing hemodialysis. PMID:27826151

    The pharmacokinetic profile of mitoxantrone in a patient undergoing hemodialysis is described. Significant characteristics of our patient included lymphoma with liver involvement, tumor lysis syndrome, renal and hepatic failure. Combination chemotherapy consisted of mitoxantrone, vincristine, and cyclophosphamide. Mitoxantrone plasma samples were obtained prior to dosing and at 0, 0.25, 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.5, 7.0, and 12 h after the intravenous infusion of a 17-mg dose over 20 min. Serum concentrations were determined by high-performance liquid chromatography. The serum concentration versus time curve was consistent with a three-compartment model. However, rebounds in serum drug concentrations were detected during the last portion of dialysis and after its completion. The gamma elimination half-life could not be determined due to the continued detection of rebounds in drug concentrations throughout the postdialysis sampling period. The alpha and beta distribution phases did not appear to be affected by hemodialysis. The peak mitoxantrone concentration fell within the reported range. Mitoxantrone does not appear to be eliminated by hemodialysis, and dose adjustments are not needed in patients undergoing this procedure.

    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.

    Sedation plays a central role in making colonoscopy tolerable for patients and feasible for the endoscopist to perform. The array of agents used for endoscopic sedation continues to evolve. Fospropofol (FP), a prodrug of propofol with a slower pharmacokinetic profile, is currently under evaluation for use during endoscopic procedures. Preliminary data suggests that FP dosed at 6.5 mg/kg is well tolerated by most patients with perineal paresthesias being the most commonly experienced adverse effect. This article will examine the current literature on the use of FP for the sedation of patients undergoing colonoscopy, highlighting the pharmacokinetics, pharmacodynamics, risks, and common adverse events associated with the novel sedative/hypnotic.

    To study the resistance to standard dosage of clopidogrel among Iranian patients following percutaneous coronary intervention measured by platelet aggregation test. Patients undergoing percutaneous coronary intervention in Imam Hussein Medical center, Tehran, Iran, who were under treatment with aspirin, but had no history of clopidogrel usage, entered the study. Patients received standard dosage of clopidogrel (Plavix®, Sanofi, France, 600 mg loading dose and 75 mg/day afterward). Platelet aggregation was measured using light transmission aggregometer. The response to the drug was categorized as complete resistance (platelet aggregation decreased less than 10%), intermediate resistance (platelet aggregation decreased between 10 to 30%) and complete response (platelet aggregation decreased to 30% or more). All patients were evaluated for major adverse cardio vascular events one month after the angioplasty based on MACE criteria by phone contact. Thirty-one patients with a mean age of 59 ± 13 entered the study. Sixty-five percent of patients showed complete response to clopidogrel (95% CI: 45% to 81%), 22% showed intermediate resistance (95% CI: 10-41%) and 13% showed complete resistance (95% CI: 4-30%). One month after the angioplasty, no major adverse cardiovascular event was recorded. Based on our findings, it seems that there is no major difference between Iranian population and other studies regarding the resistance to clopidogrel. Due to the limited number of participants in our study, further investigations with higher number of patients are recommended to more precisely calculate the percentage of resistance among Iranian patients.

    Randomised trials have shown the efficacy of antiplatelet therapy with cilostazol to prevent secondary ischaemic stroke. Recently, cilostazol has been reported to prevent the development and/or recurrence of atrial fibrillation (AF), which can potentially prevent cardioembolic stroke in patients undergoing antiplatelet therapy. Herein, we examined the impact of prior antiplatelet therapy with cilostazol on the incidence of cardioembolic stroke, which had not been fully investigated. Using the multicenter retrospective study of stroke risk in antithrombotic therapy (RESTATE) database, we analysed consecutive patients with primary or secondary stroke under single antiplatelet therapy. We evaluated the characteristics of ischaemic stroke based on the type of antiplatelet agent used: aspirin, ticlopidine/clopidogrel or cilostazol. Of 1069 consecutive patients with primary or secondary stroke during antithrombotic therapy from January to December 2012, 615 patients received single antiplatelet therapy (293 and 322 cases of primary and secondary strokes, respectively). Interestingly, the percentage of cardioembolic infarction was significantly lower in patients taking cilostazol compared with other agents. Multivariate regression analysis found that age (OR: 1.03, 95% CI: 1.01-1.06, P = 0.0029), serum creatinine (OR: 1.17, 95% CI: 1.03-1.34, P = 0.0198), aspirin (OR: 1.75, 95% CI: 1.00-3.22, P = 0.0486), cilostazol (OR: 0.19, 95% CI: 0.03-0.73, P = 0.0125), and smoking (OR: 1.86, 95% CI: 1.16-2.94, P = 0.0102) were independently associated with cardioembolic stroke. Cilostazol may prevent cardioembolic stroke in patients undergoing antiplatelet therapy. This could be a novel strategy for cardioembolic stroke prevention potentially by affecting cardiac remodelling, in contrast to secondary anticoagulant therapy.

  5. Preoperative Optimization of the Heart Failure Patient Undergoing Cardiac Surgery.

    Heart failure patients who undergo cardiac surgery are exposed to significant perioperative complications and high mortality. We herein review the literature concerning preoperative optimization of these patients. Salient findings are that end-organ dysfunction and medication should be optimized before surgery. Specifically: (1) reversible causes of anemia should be treated and a preoperative hemoglobin level of 100 g/L obtained; (2) renal function and volume status should be optimized; (3) liver function must be carefully evaluated; (4) nutritional status should be assessed and cachexia treated to achieve a preoperative albumin level of at least 30 g/L and a body mass index > 20; and (5) medication adjustments performed, such as withholding inhibitors of the renin-angiotensin-aldosterone system before surgery and continuing, but not starting, β-blockers. Levels of natriuretic peptides (brain natriuretic peptide [BNP] and N-terminal proBNP) provide additional prognostic value and therefore should be measured. In addition, individual patient's risk should be objectively assessed using standard formulas such as the EuroSCORE-II or Society of Thoracic Surgeons risk scores, which are simple and validated for various cardiac surgeries, including left ventricular assist device implantation. When patients are identified as high risk, preoperative hemodynamic optimization might be achieved with the insertion of a pulmonary artery catheter and hemodynamic-based tailored therapy. Finally, a prophylactic intra-aortic balloon pump might be considered in certain circumstances to decrease morbidity and even mortality, like in some high risk heart failure patients who undergo cardiac surgery, whereas routine preoperative inotropes are not recommended and should be reserved for patients in shock, except maybe for levosimendan.

    The incidence of bacteremia after endoscopic ultrasonography (EUS) or EUS-guided fine-needle aspiration (EUS-FNA) is between 0% and 4%, but there are no data on this topic in cirrhotic patients. To prospectively assess the incidence of bacteremia in cirrhotic patients undergoing EUS and EUS-FNA. We enrolled 41 cirrhotic patients. Of these, 16 (39%) also underwent EUS-FNA. Blood cultures were obtained before and at 5 and 30 min after the procedure. When EUS-FNA was used, an extra blood culture was obtained after the conclusion of radial EUS and before the introduction of the sectorial echoendoscope. All patients were clinically followed up for 7 days for signs of infection. Blood cultures were positive in 16 patients. In 10 patients, blood cultures grew coagulase-negative Staphylococcus, Corynebacterium species, Propionibacterium species or Acinetobacterium Lwoffii, which were considered contaminants (contamination rate 9.8%, 95% CI: 5.7-16%). The remaining 6 patients had true positive blood cultures and were considered to have had true bacteremia (15%, 95% CI: 4-26%). Blood cultures were positive after diagnostic EUS in five patients but were positive after EUS-FNA in only one patient. Thus, the frequency of bacteremia after EUS and EUS-FNA was 12% and 6%, respectively (95% CI: 2-22% and 0.2-30%, respectively). Only one of the patients who developed bacteremia after EUS had a self-limiting fever with no other signs of infection. Asymptomatic Gram-positive bacteremia developed in cirrhotic patients after EUS and EUS-FNA at a rate higher than in non-cirrhotic patients. However, this finding was not associated with any clinically significant infections. Copyright © 2013 Elsevier España, S.L. and AEEH y AEG. All rights reserved.

    [b]Introduction[/b]. Magnesium (Mg) plays a crucial role in cell physiology and its deficiency may cause many disorders which often require intensive treatment. The aim of this study was to analyse some factors affecting preoperative plasma Mg concentration in patients undergoing coronary artery bypass grafting (CABG). [b]Materials and method[/b]. Adult patients scheduled for elective CABG with cardio-pulmonary bypass (CPB) under general anaesthesia were studied. Plasma Mg concentration was analysed before surgery in accordance with age, domicile, profession, tobacco smoking and preoperative Mg supplementation. Blood samples were obtained from the radial artery just before the administration of anaesthesia. [b]Results. [/b]150 patients were studied. Mean preoperative plasma Mg concentration was 0.93 ± 0.17 mmol/L; mean concentration in patients - 1.02 ± 0.16; preoperative Mg supplementation was significantly higher than in patients without such supplementation. Moreover, intellectual workers supplemented Mg more frequently and had higher plasma Mg concentration than physical workers. Plasma Mg concentration decreases in elderly patients. Patients living in cities, on average, had the highest plasma Mg concentration. Smokers had significantly lower plasma Mg concentration than non-smokers. [b]Conclusions. [/b]1. Preoperative magnesium supplementation increases its plasma concentration. 2. Intellectual workers frequently supplement magnesium. 3. Smoking cigarettes decreases plasma magnesium concentration.

    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.

    Epilepsies is a spectrum of brain disorders ranging from severe, life threatening, and disabling to more benign, but little is known about its impact in the perioperative arthroplasty setting. We sought to determine whether epileptic patients undergoing elective total joint arthroplasty (TJA) would be at increased risk for in-hospital complications and death, prolonged stay, and nonroutine discharge. Using discharge records from the Nationwide Inpatient Sample (2002-2011), we identified 6,054,344 patients undergoing elective primary TJA, of whom 31,865 (0.5%) were identified as having epilepsy. Comparisons of perioperative outcomes were performed by multivariable logistic regression modeling. Patients with epilepsy were associated with increased in-hospital mortality (odds ratio [OR] 2.03, 95% confidence interval [CI] 1.57-2.62) and morbidity, including (in decreasing order of magnitude of effect estimate): mechanical ventilation (OR 1.74, 95% CI 1.56-1.94), induced mental disorder (OR 1.70, 95% CI 1.56-1.85), stroke (OR 1.63, 95% CI 1.23-2.15), pneumonia (OR 1.34, 95% CI 1.21-1.49), and ileus or gastrointestinal events (OR 1.26, 95% CI 1.12-1.42). Epilepsy was associated with higher risk for blood transfusion (OR 1.30, 95% CI 1.27-1.33), prolonged hospital stay (OR 1.14, 95% CI 1.11-1.17), and nonroutine discharge (OR 1.54, 95% CI 1.50-1.58). We found no association with inpatient thromboembolic events, acute renal failure, and myocardial infarction. Patients with epilepsy are at increased risk for early postoperative complications (especially mechanical ventilation, induced mental disorder, and stroke) and resource utilization after elective joint arthroplasty. Greater awareness of epilepsy and its health consequences may contribute to improvements in the perioperative management of TJA patients. Copyright © 2016 Elsevier Inc. All rights reserved.

    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

    Preoperative evaluation of patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGBP) has included esophagogastroduodenoscopy (EGD) with little data to substantiate its use. A retrospective analysis was conducted of patients from Feb 04 to Mar 05 who underwent preoperative EGD and subsequently LRYGBP. 169 patients underwent EGD prior to surgery. Their mean age was 41.1 years (range 14-66), mean BMI 49.7 (range 35-78), and 82% were females. There were no complications from EGD. Significant findings in patients at EGD included gastric ulceration in 3 (2%), duodenal ulcer in 1 (0.7%), Barrett's esophagus in 2 (1.3%), and a GI stromal tumor (GIST) in 1 (0.7%). EGD revealed hiatal hernias in 56 (35.2%), esophagitis in 28 (17%), Schatzki's ring in 5 (3%), gastritis in 43 (27%), gastric polyps in 8 (5%), and duodenitis in 9 (6%). 53 patients (33.3%) had a negative EGD. Ulcer and severe gastritis, esophagitis, and duodenitis diagnosed preoperatively were treated medically before surgery. 9 hiatal hernias were repaired intraoperatively. The patient with the GIST underwent laparoscopic near-total gastrectomy and gastric bypass, while 1 patient with an antral polyp underwent laparoscopic partial gastrectomy in addition to the LRYGBP. EGD is essential for diagnosis of GI diseases including tumors, ulcers, and hiatal hernias that alter the medical and surgical management of patients undergoing gastric bypass.

    Blood conservation is an important aspect of care provided to the patients undergoing cardiac operations with cardiopulmonary bypass (CPB). It is even more important in patients with anticipated prolonged CPB, redo cardiac surgery, patients having negative blood group and in patients undergoing emergency cardiac surgery. In prolonged CPB the blood is subjected to more destruction of important coagulation factors, in redo surgery the separation of adhesions leads to increased bleeding and difficulty in achieving the haemostasis and in patients with negative blood group and emergency operations, the availability of sufficient blood can be a problem. Harvesting the autologous platelet rich plasma (PRP) can be a useful method of blood conservation in these patients. The above four categories of patients were prospectively studied, using either autologous whole blood donation or autologous platelet rich plasma (PRP) harvest in the immediate pre-bypass period. Forty two patients were included in the study and randomly divided into two equal groups of 21 each, control group (Group I) in which one unit of whole blood was withdrawn, and PRP group (Group II) where autologous plateletpheresis was utilised. After reversal of heparin, autologous whole blood was transfused in the control group and autologous PRP was transfused in the PRP group. The chest tube drainage and the requirement of homologous blood and blood products were recorded. Average PRP harvest was 643.33 +/- 133.51 mL in PRP group and the mean whole blood donation was 333.75 +/- 79.58 mL in the control group. Demographic, preoperative and intra operative data showed no statistically significant differences between the two groups. The PRP group patients drained 26.44% less (p<0.001) and required 38.5% less homologous blood and blood products (p<0.05), in the postoperative period. Haemoglobin levels on day zero (day of operation) and day three were statistically not different between the two groups. We conclude

    Post-operative management in gastrointestinal (GI) surgery is becoming well established with 'Enhanced Recovery After Surgery' protocols starting 24 hours prior to surgery with carbohydrate loading and early oral or enteral feeding given to patients the first day following surgery. However, whether or not nutritional intervention should be initiated earlier in the preoperative period remains unclear. Poor pre-operative nutritional status has been linked consistently to an increase in post-operative complications and poorer surgical outcome. To review the literature on preoperative nutritional support in patients undergoing gastrointestinal surgery (GI). The searches were initially run in March 2011 and subsequently updated in February 2012. Databases including all EBM Reviews (Cochrane DSR, ACP Journal Club, DARE, CCTR, CMR, HTA and NHSEED) MEDLINE, EMBASE, AMED, British Nursing Index Archive using OvidSP were included and a search was run on each database separately after which duplicates were excluded. The inclusion criteria were randomised controlled trials that evaluated pre-operative nutritional support in GI surgical participants using a nutritional formula delivered by a parenteral, enteral or oral route. The primary outcomes included post-operative complications and length of hospital stay. Two observers screened the abstracts for inclusion in the review and performed data extraction. Bias was assessed for each of the included studies using the bias assessment tables in the Cochrane Software Review Manager (version 5.1, Cochrane Collaboration). The trials were analysed using risk ratios with Mantel-Haenszel in fixed effects methods displayed with heterogeneity. Meta-analyses were undertaken on trials evaluating immune enhancing (IE) nutrition, standard oral supplements, enteral and parenteral nutrition (PN) which were administered pre-operatively.Study characteristics were summarised in tables.

    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

    To retrospectively assess the value of intraoperative transesophageal echocardiography (TEE) during robotic mitral valve (MV) replacement. Intraoperative TEE was performed in 21 patients undergoing robotic MV replacement for severe rheumatic mitral stenosis between November 2008 and December 2010. During the procedure, TEE was performed to document the mechanism of rheumatic mitral stenosis (leaflet thickening and calcification, commissural fusion or chordal fusion) before cardiopulmonary bypass (CPB). During the establishment of peripheral CPB, TEE was used to guide the placement of the cannulae in the inferior vena cava (IVC), superior vena cava (SVC), and ascending aorta (AAO). After weaning from CPB, TEE was performed to evaluate the effect of the procedure. Accuracy of TEE was 100% for rheumatic mitral stenosis. All the cannuli in the SVC, IVC and AAO were located in the correct position. In all patients, TEE confirmed successful procedure. TEE is useful in the assessment of robotic MV replacement.

    The aim of this study was to investigate prospectively the incidence of deep venous thrombosis (DVT) after surgery for morbid obesity. The series comprised 116 consecutive patients undergoing Roux-en-Y gastric bypass. The median age and body mass index were 35 years (range 19-59 years) and 42 kg/m2 (range 32-68 kg/m2), respectively. The patients were examined with duplex ultrasonography pre- and postoperatively. No patient had any symptoms or signs of DVT postoperatively, and ultrasonography showed no signs of thrombosis in iliac, femoral, and popliteal veins in any of the patients. Two patients (1.7%) had a thrombus in the peroneal vein of one leg. Repeated ultrasonographic investigation after 1 week showed complete resolution of both. One patient with a previously unknown activated protein C resistance had an angiographically confirmed minor pulmonary embolus. The incidence of venous thromboembolism after obesity surgery seems to be low, and obesity as a risk factor for thromboembolic disease might have been overestimated in the past.

    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

    The aim of this review is to formulate practical recommendations for the management of antithrombotic therapy in patients undergoing cardiac implantable electronic device (CIED) surgery by providing indications for a systematic approach to the problem integrating general technical considerations with patient-specific elements based on a careful evaluation of the balance between haemorrhagic and thromboembolic risk. Hundreds of thousands patients undergo implantation or replacement of CIEDs annually in Europe, and up to 50% of these subjects receive antiplatelet agents or oral anticoagulants. The rate of CIED-related complications, mainly infective, has also significantly increased so that transvenous lead extraction procedures are, consequently, often required. Cardiac implantable electronic device surgery is peculiar and portends specific intrinsic risks of developing potentially fatal haemorrhagic complications; on the other hand, the periprocedural suspension of antithrombotic therapy in patients with high thromboembolic risk cardiac conditions may have catastrophic consequences. Accordingly, the management of the candidate to CIED surgery receiving concomitant antithrombotic therapy is a topic of great clinical relevance yet controversial and only partially, if at all, adequately addressed in evidence-based current guidelines. In spite of the fact that in many procedures it seems reasonably safe to proceed with aspirin only or without interruption of anticoagulants, restricting to selected cases the use of bridging therapy with parenteral heparins, there are lots of variables that may make the therapeutic choices challenging. The decision-making process applied in this document relies on the development of a stratification of the procedural haemorrhagic risk and of the risk deriving from the suspension of antiplatelet or anticoagulant therapy combined to generate different clinical scenarios with specific indications for optimal management of periprocedural

    The incidence of bleeding and thrombo-embolic complications in patients undergoing mechanical circulatory support therapy remains high and is associated with bad outcomes and increased costs. The need for anticoagulation and anti-platelet therapy varies widely between different pulsatile and non-pulsatile ventricular-assist devices (VADs) and extracorporeal membrane oxygenation (ECMO) systems. Therefore, a unique anticoagulation protocol cannot be recommended. Notably, most thrombo-embolic complications occur despite values of conventional coagulation tests being within the targeted range. This is due to the fact that conventional coagulation tests such as international normalised ratio (INR), activated partial thromboplastin time (aPTT) and platelet count cannot detect hyper- or hypofibrinolysis, hypercoagulability due to tissue factor expression on circulating cells or increased clot firmness, and platelet aggregation as well as response to anti-platelet drugs. By contrast, point-of-care (POC) whole blood viscoelastic tests (thromboelastometry/-graphy) and platelet function tests (impedance or turbidimetric aggregometry) reflect in detail the haemostatic status of patients undergoing mechanical circulatory support therapy and the efficacy of their anticoagulation and antiaggregation therapy. Therefore, monitoring of haemostasis using POC thromboelastometry/-graphy and platelet function analysis is recommended during mechanical circulatory support therapy to reduce the risk of bleeding and thrombo-embolic complications. Notably, these haemostatic tests should be performed repeatedly during mechanical circulatory support therapy since thrombin generation, clot firmness and platelet response may change significantly over time with a high inter- and intra-individual variability. Furthermore, coagulation management can be hampered in non-pulsatile VADs by acquired von Willebrand syndrome, and in general by acquired factor XIII deficiency as well as by heparin

    The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed as an extensive question bank with multiple health domains that could be utilized for computerized adaptive testing (CAT). In the present study, we investigated the use of the PROMIS Physical Function CAT (PROMIS PF CAT) in an otherwise healthy population scheduled to undergo surgery for meniscal injury with the hypotheses that (1) the PROMIS PF CAT would correlate strongly with patient-reported outcome instruments that measure physical function and would not correlate strongly with those that measure other health domains, (2) there would be no ceiling effects, and (3) the test burden would be significantly less than that of the traditional measures. Patients scheduled to undergo meniscal surgery completed the PROMIS PF CAT, Knee injury and Osteoarthritis Outcome Score (KOOS), Marx Knee Activity Rating Scale, Short Form-36 (SF-36), and EuroQol-5 Dimension (EQ-5D) questionnaires. Correlations were defined as high (≥0.7), high-moderate (0.61 to 0.69), moderate (0.4 to 0.6), moderate-weak (0.31 to 0.39), or weak (≤0.3). If ≥15% respondents to a patient-reported outcome measure obtained the highest or lowest possible score, the instrument was determined to have a significant ceiling or floor effect. A total of 107 participants were analyzed. The PROMIS PF CAT had a high correlation with the SF-36 Physical Functioning (PF) (r = 0.82, p < 0.01) and KOOS Sport (r = 0.76, p < 0.01) scores; a high-moderate correlation with the KOOS Quality-of-Life (QOL) (r = 0.63, p < 0.01) and EQ-5D (r = 0.62, p < 0.01) instruments; and a moderate correlation with the SF-36 Pain (r = 0.60, p < 0.01), KOOS Symptoms (r = 0.57, p < 0.01), KOOS Activities of Daily Living (ADL) (r = 0.60, p < 0.01), and KOOS Pain (r = 0.60, p < 0.01) scores. The majority (89%) of the patients completed the PROMIS PF CAT after answering only 4 items. The PROMIS PF CAT had no floor or ceiling effects, with 0% of the

    AIM To evaluate frequency and clinical course of incidental adenocarcinoma in patients with stricturing Crohn's disease (CD). METHODS In this study, consecutive patients, who were operated on for stricturing CD between 1997-2012, were included at an academic tertiary referral center. Demographic data and clinical course were obtained by an institutional database and individual chart review. Besides baseline characteristics, intraoperative findings and CD related history were also recorded. Colorectal cancer was classified and staged according to the Union for International Cancer Control (UICC). RESULTS During the study period 484 patients underwent resections due to stricturing CD. Incidental adenocarcinoma was histologically confirmed in 6 (1.2%) patients (4 males, 2 females). Patients diagnosed with colorectal cancer had a median age of 43 (27-66) years and a median history of CD of 16 (7-36) years. Malignant lesions were found in the rectum (n = 4, 66.7%), descending colon (n = 1, 16.7%) and ileocolon (n = 1, 16.7%). According to the UICC classification two patients were stages as I (33.3%), whereas the other patients were classified as stage IIA (16.7%), stage IIIB (16.7%), stage IIIC (16.7%) and stage IV (16.7%), respectively. After a median follow-up of 2 (0.03-8) years only 1 patient is still alive. CONCLUSION The frequency of incidental colorectal cancer in patients, who undergo surgery for stenotic CD, is low but associated with poor prognosis. However, surgeons need to be aware about the possibility of malignancy in stricturing CD, especially if localized in the rectum. PMID:28210083

    Perioperative temperature management is imperative for positive surgical outcomes. This study assessed the clinical and wellbeing benefits of extending normothermia by using a portable warming gown. A total of 94 patients undergoing elective surgery were enrolled. They were randomized pre-operatively to either a portable warming gown or the standard warming procedure. The warming gown stayed with patients from pre-op to operating room to postrecovery room discharge. Core temperature was tracked throughout the study. Patients also provided responses to a satisfaction and comfort status survey. The change in average core temperature did not differ significantly between groups (P = 0.23). A nonsignificant 48% relative decrease in hypothermic events was observed for the extended warming group (P = 0.12). Patients receiving the warming gown were more likely to report always having their temperature controlled (P = 0.04) and significantly less likely to request additional blankets for comfort (P = 0.006). Clinical outcomes and satisfaction were improved for patients with extended warming.

    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.

    This prospective randomised study was designed to evaluate the efficacy of intradialytic parenteral nutrition (IDPN) therapy in malnourished patients with refractory anaemia. Forty patients who were malnourished with a BMI not greater than 23 (17-23) kg/m(2) , undergoing regular HD were included. Of those, 20 patients received 500-1000 ml of IDPN at a rate of 250-300 ml/h at each HD session three days per week for six consecutive months. The other 20 patients did not receive IDPN infusion. The malnutrition inflammation score (MIS) and haematological parameters were recorded at baseline and after three and six months. Mean haemoglobin levels, BMI and serum albumin were significantly increased while MIS was significantly decreased after the 3rd and 6th months of IDPN. IDPN has a good role in improving refractory anaemia by significantly increasing haemoglobin levels, body weight, and serum albumin levels. The intervention also significantly decreases the MIS of patients. © 2017 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    Because of a much higher dynamic range of flat panel detectors, patient dose can vary without change of image quality being perceived by radiologists. This condition makes optimization (OT) of radiation protection undergoing digital radiography (DR) more complex, while a chance to reduced patient dose also exists. In this study, we evaluated the difference of patient radiation and image rejection before and after OT to identify if it is necessary to carry out an OT procedure in a routine task with DR. The study consisted of a measurement of the dose area product (DAP) and entrance surface dose (ESD) received by a reference group of patients for eight common radiographic procedures using the DR system before and after OT. Meanwhile image rejection data during two 2-month periods were collected and sorted according to reason. For every radiographic procedure, t tests showed significant difference in average ESD and DAP before and after OT (p < 0.005). The ESDs from most examinations before OT were three times higher than that after OT. For DAPs, the difference is more significant. Image rejection rate after OT is significantly lower than that before OT (χ (2) = 36.5, p < 0.005). The substantial reductions of dose after OT resulted from appropriate mAs and exposure field. For DR patient dose, less than recommended diagnostic reference level can meet quality criteria and clinic diagnosis.

    The rapid growth (1-6 days) of the functionally overloaded soleus muscle, in response to tenotomy of the synergist gastrocnemius, was found to correlate with increases in both the protein synthetic and degradative rates, the change in the former being greater than that of the latter. These conclusions were drawn from two different methods used to measure (in vivo and in vitro) the average rates of protein synthesis and protein breakdown in these soleus muscles. Although the basal rates of synthesis were higher when measured in vivo, and the degradative rates higher in isolated muscle preparations incubated in vitro, both methods gave good agreement concerning the changes in protein turnover induced by tenotomy of the gastrocnemius. The possible involvement of passive stretch in inducing this additional growth is discussed. As an antagonist to the soleus, growth of the extensor digitorum longus muscle was decreased under the same conditions, presumably because of less usage. At 3 days after the cutting of the sciatic nerve, the previously normal or overloaded soleus muscles underwent rapid atrophy. Although in both cases RNA and protein were lost, while protein synthesis decreased and protein breakdown increased, denervation induced larger changes within these parameters of the formerly overloaded muscle. The slowing of growth in the tenotomized gastrocnemius, and its subsequent rapid atrophy after additional denervation, were explained by large increases in protein breakdown, with little or no change in the synthetic rate.

    The pharmacokinetics of ampicillin and sulbactam, a new beta-lactamase inhibitor, were investigated in 16 patients undergoing prosthetic cardiac valve insertion. The combination of 2 g of ampicillin and 1 g of sulbactam was administered as perioperative prophylaxis intravenously over 3 to 6 days. Several serum pharmacokinetic parameters were similar for the two drugs after three intravenous doses were given to patients following surgery. The half-lives of elimination of ampicillin and sulbactam were 79 +/- 4.9 and 88 +/- 5.9 min, the volumes of distribution were 15.6 +/- 1.4 and 17.7 +/- 1.2 liters/70 kg, and the total plasma clearances were 144.4 +/- 14.5 and 147.2 +/- 14.5 ml/min, respectively. The peak concentrations of ampicillin and sulbactam in serum were calculated to be 134.3 +/- 1.3 and 58.3 +/- 1.2 micrograms/ml, respectively. Ampicillin and sulbactam rapidly penetrated from the blood into various tissues collected during heart surgery, such as sternum, pericardium, myocardium, and endocardium. The concentrations of ampicillin in tissue ranged from 17.8 +/- 9.9 to 50 +/- 29.5 micrograms/g, and those of sulbactam in tissue ranged from 8.8 +/- 6.2 to 19.6 +/- 10.1 micrograms/g. The concentrations of ampicillin and sulbactam in serum and tissue also apparently exceeded the MICs against most beta-lactamase-producing bacteria usually involved in postoperative wound infections and prosthetic valve endocarditis. The ratio of the two compounds was approximately 2:1 in serum and in the various tissues affected by the operation. The pharmacokinetics of ampicillin and sulbactam in serum and investigated tissues suggest that the combination of the two beta-lactams will be effective in the perioperative prophylaxis of patients undergoing heart surgery.

    Reporting the experiences and satisfaction of patients, as well as their quality of care scores is an emerging recommendation in health care systems. Many aspects of patients' experience determine their overall satisfaction. The aim of this evaluation was to define the main factors contributing to the satisfaction of patients undergoing radiotherapy in an outpatient setting. A total of 1,710 patients with a histologically proven cancer, who were treated in our department between 2012 and 2014, were recruited for this prospective evaluation. At the end of therapy, each patient was asked to grade the skills and the care provided by radiation therapists, physicians, and physician's assistants, as well as the overall satisfaction during therapy. Statistical analysis was performed to determine which parameters had the greatest influence on overall satisfaction. Overall satisfaction with the provided care was high with a mean satisfaction score of 1.4. Significant correlations were found between overall satisfaction and each of the following survey items: courtesy, protection of privacy, professional skills and care provided by the radiation therapists and physicians, accuracy of provided information, and cleanliness. Linear regression analysis demonstrated that courteous behavior and the protection of privacy were the strongest predictors for overall satisfaction (P<0.001), followed by care and skills of physicians and radiation therapists. Patients suffering from head and neck cancer expressed lower overall satisfaction. Based on our prospectively acquired data, we were able to identify and confirm key factors for patient satisfaction in an outpatient radiooncological cancer center. From these results, we conclude that patients want most importantly to be treated with courtesy, protection of privacy and care.

    Unexpected cardiopulmonary complications are well described during surgery and anesthesia. Pre-operative evaluation by focused cardiopulmonary ultrasonography may prevent such mishaps. The aim of this study was to determine the frequency of unexpected cardiopulmonary pathology with focused ultrasonography in patients undergoing urgent surgical procedures. We performed pre-operative focused cardiopulmonary ultrasonography in patients aged 18 years or above undergoing urgent surgical procedures at pre-defined study days. Known and unexpected cardiopulmonary pathology was recorded, and subsequent changes in the anesthesia technique or supportive actions were registered. A total of 112 patients scheduled for urgent surgical procedures were included. Their mean age (standard deviation) was 62 (21) years. Of these patients, 24% were American Society of Anesthesiologists (ASA) class 1, 39% were ASA class 2, 32% were ASA class 3, and 4% were ASA class 4. Unexpected cardiopulmonary pathology was disclosed in 27% [95% confidence interval (CI) 19-36] of the patients and led to a change in anesthesia technique or supportive actions in 43% (95% CI 25-63) of these. Unexpected pathology leading to changes in anesthesia technique or supportive actions was only disclosed in a group of patients above the age of 60 years and/or in ASA class ≥ 3. Focused cardiopulmonary ultrasonography disclosed unexpected pathology in patients undergoing urgent surgical procedures and induced changes in the anesthesia technique or supportive actions. Pre-operative focused ultrasonography seems feasible in patients above 60 year and/or with physical limitations but not in young, healthy individuals. © 2014 The Acta Anaesthesiologica Scandinavica Foundation.

    Medication nonadherence is problematic throughout health care practice. Patient nonadherence is a result of several factors, such as financial issues, confusion about the medication, or concerns about possible side effects. Efforts to improve adherence have been implemented, but new strategies are needed to ensure that patients fill their medication prescriptions and adhere to their prescribed use. To investigate whether providing patients with a free 30-day supply of medication at the point of care via a dispensing kiosk-a secure, computerized cabinet placed in the prescriber's office-that provides sample medication and educational materials had a measurable impact on adherence and health care cost. The study sample consisted of patients drawn from the electronic health records of a large health care provider who were prescribed medications to treat diabetes, hypertension, and dyslipidemia. The comparison groups included a treatment group of patients who each received a 30-day generic sample of medication and a control group of patients who did not receive a sample. The study outcome was primary medication non-adherence (PMN), defined as whether a patient filled a prescription within 90, 180, or 365 days of prescribing. Only patients receiving a prescription for the first time were considered; patients on a medication before receipt of the sample were dropped. Postprescription medication adherence (PPMA), measured as proportion of days covered (PDC) and proportion of days covered ≥ 80% (PDC80), was also examined. Propensity score methods and multivariate regression models were used to examine the outcomes and group differences. Costs to the patient before and after the prescription were also analyzed. Key informant interviews were conducted with physicians, and qualitative analyses were performed. Patients who received a 30-day generic medication sample had a higher probability of filling a first prescription within 90 days (72.2% for treatment patients vs. 37

    Prior to June 2011, carotid artery stenting (CAS) had been limited to patients deemed high risk for surgical revascularization due to medical or anatomic reasons. Intraprocedural anticoagulation for CAS has traditionally been carried out with unfractionated heparin (UFH). The direct thrombin inhibitor bivalirudin has emerged as a possible alternative choice for anticoagulation in this patient population. In patients undergoing coronary interventions, bivalirudin has been shown in large prospective analysis to reduce major adverse events and hemorrhagic complications (TIMI major bleeding rates, 0.6%-3.1%; TIMI minor bleeding rates, 1.3%-3.7%). As of now, the safety and efficacy of bivalirudin for use during carotid stenting has not been rigorously evaluated. To date, the published evidence in favor of bivalirudin for CAS exists in small retrospective analyses and two prospective studies. We present a retrospective analysis of 331 patients with a total of 365 carotid artery lesions undergoing CAS between February 2007 and September 2010. The procedures were performed by five experienced operators from four separate sites within the same metropolitan area. Patients were included who received bivalirudin as the anticoagulation strategy and underwent CAS. The primary endpoints of the study were 30-day incidence of death, stroke, TIMI major bleeding (defined as ≥5 g/dL Hgb drop or intracranial hemorrhage), TIMI minor bleeding (defined as ≥3 g/dL Hgb drop), and blood transfusion. All data were collected by retrospective chart review. A total of 365 CAS procedures were performed. There were no deaths, strokes, or TIMI major bleeds. There was a 2.19% incidence of TIMI minor bleeding (8/365) and a 1.64% rate of blood transfusion (6/365). In our patient population, the major endpoints of stroke, death, MI, major and minor bleeding rates were well within those previously reported overall for carotid artery revascularization. Hence, we conclude that bivalirudin may be safe

    informed consent is a fundamental and legal obligation for each interventional cardiologist. The effect of consent form describing risks of invasive procedure on anxiety is controversial. This trial was aimed to assess the added value of video information to the standard informed consent process. 200 consecutive patients undergoing coronary angiography were enrolled. The first one hundred were assigned to conventional education conducted by the physician (no video group) and the second one hundred had consent obtained in the conventional manner assisted by video information (video group). The outcome variables for this comparison consisted of a standard anxiety score (Spielberger Statement Anxiety Inventory questionnary) plus hemodynamics measurements of heart rate, systolic and diastolic blood pressure obtained at baseline and immediately after written informed consent In addition, before discharge, patients graded the tolerability and satisfaction on a 4-point scale. The groups were similar with regard to their baseline characteristics and anxity score (37+23 vs 37+23). Patients who had not had prior experience of catheterization had higher baseline anxiety than those who had prior angiography (45 + 22 vs 31 + 20; p = 0.027). Patients who watched the video were significantly less anxious after informed consent (28 + 21 vs 34 + 22; p = 0.048) and had a significantly lower heart rate (65 + 10 vs 71 + 12; p = 0.03). The benefits of video information were especially prominent in those with higher anxiety scores at baseline (score after 45 + 24 vs 57 + 26; p = 0.046). Tolerability were higher in the video group compared with no video group (98% vs 86%; p = 0.003). Finally, satisfaction of information for informed consent process was higher in video group than in no video group (99% vs 76%; p = 0.001). a video information decreased anxiety level after written informed consent and improved tolerability and satisfaction scales in patients undergoing coronary angiography

    Background Levosimendan is an inotropic agent that has been shown in small studies to prevent or treat the low cardiac output syndrome after cardiac surgery. Methods In a multicenter, randomized, placebo-controlled, phase 3 trial, we evaluated the efficacy and safety of levosimendan in patients with a left ventricular ejection fraction of 35% or less who were undergoing cardiac surgery with the use of cardiopulmonary bypass. Patients were randomly assigned to receive either intravenous levosimendan (at a dose of 0.2 μg per kilogram of body weight per minute for 1 hour, followed by a dose of 0.1 μg per kilogram per minute for 23 hours) or placebo, with the infusion started before surgery. The two primary end points were a four-component composite of death through day 30, renal-replacement therapy through day 30, perioperative myocardial infarction through day 5, or use of a mechanical cardiac assist device through day 5; and a two-component composite of death through day 30 or use of a mechanical cardiac assist device through day 5. Results A total of 882 patients underwent randomization, 849 of whom received levosimendan or placebo and were included in the modified intention-to-treat population. The four-component primary end point occurred in 105 of 428 patients (24.5%) assigned to receive levosimendan and in 103 of 421 (24.5%) assigned to receive placebo (adjusted odds ratio, 1.00; 99% confidence interval [CI], 0.66 to 1.54; P=0.98). The two-component primary end point occurred in 56 patients (13.1%) assigned to receive levosimendan and in 48 (11.4%) assigned to receive placebo (adjusted odds ratio, 1.18; 96% CI, 0.76 to 1.82; P=0.45). The rate of adverse events did not differ significantly between the two groups. Conclusions Prophylactic levosimendan did not result in a rate of the short-term composite end point of death, renal-replacement therapy, perioperative myocardial infarction, or use of a mechanical cardiac assist device that was lower than the rate

    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.

    A 25-year-old man was admitted for arm replantation. His left upper arm was completely amputated by conveyer belt Anesthesia was induced with propofol (80 mg), rocuronium (50 mg), remifentanil (0.15 μg x kg(-1) x min(-1)) and maintained with sevoflurane (1-2%) and remifentanil (0.1-0.3 μg x kg(-1) x min(-1)). The plastic surgeons revascularized subclavian artery quickly but blood pressure decreased to 40-50 mmHg because of massive bleeding and plasma potassium concentration reached 5.8 mEq x l(-1). Noradrenaline (0.3 μg x kg(-1) x min(-1)) and massive albumin on behalf of red blood cells were administered. After we treated hyperkalemia and hypotension, the subclavian vein was successfully revascularized. We should maintain low potassium concentration before revascularization in patients undergoing arm replantation.

    Evaluation of physiotherapeutic provision for patients undergoing open thoracotomy and lung surgery in the U.K. Timing of physiotherapy, modalities used and factors influencing practice were also investigated. Survey. Tertiary centres performing thoracic surgery. Forty U.K. centres were identified, and senior physiotherapists were invited to participate. A postal survey was distributed to identified centres in August 2008, with further follow-up of non-responders. This was adapted from a similar study conducted in Australia and New Zealand. Thirty-one responses were received (78%). Pre-operative physiotherapy was provided by 87% of respondents: 10% provided physiotherapy for all patients and 77% only provided physiotherapy for high-risk patients. Pre-operative pulmonary rehabilitation was reported in 13% of centres. Postoperative physiotherapeutic assessment was undertaken routinely by 97% of respondents: 81% provided physiotherapy to all patients, and 16% only provided physiotherapy when a specific problem was identified. The treatments given were relatively standardised. The provision of physiotherapy following hospital discharge was generally very sparse. This study provides a guide for physiotherapists working with patients undergoing thoracic surgery to use to compare their current practices. Postoperative physiotherapy is provided extensively to UK patients undergoing open thoracotomy. However, pre-operative provision is more variable and is mainly provided for high-risk patients. Despite the subsequent publication of pre- and postoperative pulmonary rehabilitation studies, UK physiotherapy practice remained similar to that reported in Australia and New Zealand. Further research in this field is necessary to investigate the role of pre-operative physiotherapy, the role of pre- and postoperative pulmonary rehabilitation, and the effectiveness of routine postoperative physiotherapy.

    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

    OBJECTIVE Postoperative urinary retention (POUR) is a common problem leading to morbidity and an increased hospital stay. There are limited data regarding its baseline incidence in patients undergoing spinal surgery and the risk factors with which it may be associated. The purpose of this study was to evaluate the incidence of POUR in elective spine surgery patients and determine the factors associated with its occurrence. METHODS The authors retrospectively reviewed the records of patients who had undergone elective spine surgery and had been prospectively monitored for POUR during an 18-month period. Collected data included operative positioning, surgery duration, volume of intraoperative fluid, length of hospital stay, and patient characteristics such as age, sex, and medical comorbidities. Dialysis patients or those with complete urinary retention preoperatively were excluded from analysis. RESULTS Of the 397 patients meeting the study inclusion criteria, 35 (8.8%) developed POUR. An increased incidence of POUR was noted in those who underwent posterior lumbar surgery, those with benign prostatic hypertrophy (BPH), those with chronic constipation or prior urinary retention, and those using a patient-controlled analgesia pump postoperatively. An increased incidence of POUR was seen with a longer operative time but not with intraoperative intravenous fluid administration. A significant relationship between the female sex and POUR was noted after controlling for BPH, yet there was no association between POUR and diabetes or intraoperative instrumentation. Postoperative retention significantly prolonged the hospital stay. Three patients developed epidural hematomas necessitating operative reexploration, and while they experienced POUR, they also developed the full constellation of cauda equina syndrome. CONCLUSIONS Awareness of the risk factors for POUR may be useful in perioperative Foley catheter management and in identifying patients who need particular

    Therapeutic hypothermia (TH) is recommended to minimize neurological damage in patients surviving sudden cardiac arrest (SCA). There is scarcity of data evaluating the nursing workload in these patients. The objective of the study is to assess the workload of nurses whilst treating patients undergoing TH after SCA. A 43-month prospective-retrospective comparative cohort study was designed. Patients admitted to intensive care unit, for recovered SCA and persistent coma, were included. A comparison was made using the baseline characteristics, medical management, in-hospital mortality, and nursing workload during the first 96hours using the Therapeutic Intervention Scoring System-28 (TISS-28); Nursing Activities Score (NAS); and Nine Equivalents of Nursing Manpower Use Score (NEMS) scales among patients who received TH and those who did not. A total 46 patients were included: 26 in the TH group and 20 in the Non-TH group. Regarding baseline characteristics and management, the TH group presented higher prevalence of smoking habit (69 vs. 25%, p=0.012), out-of-hospital SCA (96 vs. 55%, p<0.001), and the performance of coronary angiography (96 vs. 65%, p=0.014) compared with the non-TH group. No differences were observed in the nursing workload, assessed by TISS 28, NAS or NEMS scales, or in-hospital mortality. In this study performance of TH in SCA survivors is not associated with an increase in nursing workload. The installation of a TH program does not require the use of more nursing resources in terms of workload. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

    Dermatologists have championed Mohs micrographic surgery (MMS) for its unsurpassed treatment success for skin cancers, safety profile, cost-effectiveness, and tissue-sparing quality. It is unclear whether patients undergoing MMS also value these characteristics. To evaluate patients' preoperative expectations of MMS and identify the factors that may influence such expectations The study prospectively recruited participants who were newly diagnosed with skin cancer and referred for MMS. A questionnaire listing the characteristics of MMS was given to the participants asking them to score the importance of each characteristic on a 10-point scale. The participants were also asked to provide information regarding their gender, age, subjective health status, education level, family annual income, and their referral source On average, participants placed the highest value, in descending order, on a treatment that yielded the highest cure rate, reconstruction initiation only after complete tumor removal, and the surgeon being a skin cancer specialist. Overall, participants placed high values on characteristics of MMS that dermatologists have long esteemed. Our data corroborate that MMS is a valuable procedure that meets the expectations not just of physicians, but also of patients. The authors have indicated no significant interest with commercial supporters. © 2011 by the American Society for Dermatologic Surgery, Inc.

    2016-01-01

    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

  3. 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

    Patients undergoing bariatric surgery often complain of bad breath. However, the relationship between bariatric surgery and halitosis is relatively unknown. The purpose of the present study was to evaluate and compare the occurrence of halitosis among patients before and after a specific type of bariatric surgery, Roux-en-Y gastric bypass, and its relationship with the tongue coating index, plaque index, and salivary flow rate. A total of 62 patients with good oral health and in treatment for obesity at the walk-in clinic of Santa Casa Hospital, Belo Horizonte, Brazil, were selected. Of this sample, 31 were bariatric surgery candidates (control group) and 31 had already undergone Roux-en-Y gastric bypass surgery (case group). After completing a questionnaire, all patients underwent an oral clinical examination. Halitosis was measured using an organoleptic scale and a portable sulfide monitor. The Spearman correlation demonstrated a strong positive relation between the organoleptic rates and the concentration of volatile sulfur compounds determined using the sulfide monitor (rs = .58; P = .0001). No difference was found in the prevalence of halitosis between the 2 groups (P = .48). Only the salivary flow rate was significantly reduced in the control group compared with the case group (P = .02). In the case group, the concentration of volatile sulfur compounds correlated negatively with the salivary flow rate (P = .04) and positively with the tongue coating index (P = .005). The tongue coating index was significantly increased in those patients who did not brush the tongue (P < .04) and who had had episodes of vomiting (P = .02). These data suggest that no significant association exists between halitosis and Roux-en-Y gastric bypass. However, they do highlight the possible effect of this surgery on the oral cavity.

    To assess perioperative management of patients with diabetes mellitus who were being treated with insulin pump therapy. We reviewed records for documentation of insulin pump status and glucose monitoring during preoperative, intraoperative, and postanesthesia care unit (PACU) phases of surgery. Thirty-five patients (21 men) with insulin pumps underwent surgical procedures between January 1, 2006, and December 31, 2010. Mean age was 56 years, mean diabetes duration was 31 years, and mean duration of insulin pump therapy was 7 years. All patients were white, and 29 had type 1 diabetes mellitus. Of the 50 surgical procedures performed during the study period, 16 were orthopedic, 9 were general surgical, 7 were urologic, and 7 were kidney transplant operations; the remaining 11 procedures were in other surgical specialties. The mean (± standard deviation) time in the preoperative area was 118 ± 75 minutes, mean intraoperative time was 177 ± 102 minutes, and mean PACU time was 170 ± 78 minutes. Of the 50 procedures, status of pump use was documented in 32 cases in the preoperative area, 14 cases intraoperatively, and 30 cases in the PACU. Glucose values were recorded in 47 cases preoperatively, 30 cases intraoperatively, and 48 cases in the PACU. Results showed inconsistent documentation of pump use and glucose monitoring throughout the perioperative period, even for patients with prolonged anesthesia and recovery times. It was often unclear whether the pump was in place and operational during the intraoperative period. Guidelines should be developed for management of insulin pump-treated patients who are to undergo surgery.

    Background An adequate bowel preparation is an important quality measure for optimal colonoscopy. Aims The aim of this article is to study the burden of bowel preparations by examining seven specific variables (hunger, taste, volume, sleep, social, work, and adverse events (AEs)). Methods Ambulatory patients undergoing elective colonoscopy completed a questionnaire regarding their experience with the prescribed preparation. The seven study variables were graded using a numerical scale of 0–10 (best to worst). A score >6 was considered to indicate a significant impact and used as primary outcome. Patients were also asked to grade in descending order what they perceived as the worst aspect of the preparation. Results A total of 216 patients completed the survey. Preparations consisted of split-dose sodium picosulfate (SPS) (n = 49), split-dose 4 l PEG ± menthol (n = 49), full-dose PEG (n = 68), and 2 l split-dose PEG + ascorbic acid (n = 50). Except for work and AEs, all variables were considered to have a negative impact by >20% of patients (range 20.4–34.2). SPS was superior to PEG regimens in taste (4.1% vs. 35.9%) and volume (0% vs. 44.9%) (p < 0.05 for both) but inferior for hunger (30.6% vs. 19.2%; p = 0.09). The addition of menthol to PEG significantly improved taste (22.4% vs. 41.5%; p = 0.02). Sleep disturbances were most common with SPS and least with split-dose PEG (30.6% vs. 17.4%; p < 0.05). Overall, patients ranked volume, taste, and hunger as most burdensome. Conclusions The burden of bowel preparation is substantial. An informed personalized choice of preparation may improve adherence, tolerability and colon cleansing. PMID:27087962

    There is an evident need for procedural protocol for oral surgery patients who undergo oral anticoagulant treatment (OAT) because of: 1) the possible severity of complications and 2) the growing demand for OAT, which in some cases may be as much as 8% of the oral surgery patients that are referred to the hospital from primary care centers. In this study, the authors define the parameters for creating a proto- col applicable to this group of patients. The conclusion is that it is not necessary to suspend OAT before surgery; rather, these procedures should be performed under multidisciplinary medical control. The authors demonstrate that it is possible to perform oral surgery on OAT patients, without having to sus- pend treatment beforehand. A longitudinal study was performed in OAT patients that required some type of oral surgical procedures. After an INR control, the patient underwent surgery and afterwards the patient was given tranexamic acid as a mouth rinse. Postoperative hemorrhage was classified as slight when it lasted less than 5 minutes, moderate when it lasted longer than five minutes, and severe when it required blood transfusion. The study was performed over a 5-year period (1996-2000), by the maxillofacial surgery department. In that time period, 125 patients with OAT were treated; 90 of them were males and 35 were females. Tooth extraction was per- formed in 229 sessions and a total of 367 teeth were extracted, with an average of 1.6% per session. With regards to postoperative hemorrahage, it was slight in 210 cases (91.7%), moderate in 18 (7.9%) and severe only in one case (0.4%). All the variables were compared and no statistically significant differences were found. We believe that OAT should not be suspended before oral surgery, but it surgery should be performed under multidisciplinary control-especially in the case of the elderly (over 65) or with those patients that have other concomitant illnesses such as renal insufficiency or anemia or other

    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

    Cancer patients are at increased risk for postoperative sepsis. However, studies addressing the issue are lacking. We sought to identify preoperative and intraoperative predictors of 30-d sepsis after major cancer surgery (MCS) and derive a postoperative sepsis risk stratification tool. Patients undergoing one of nine MCSs (gastrointestinal, urological, gynecologic, or pulmonary) were identified within the American College of Surgeons National Surgical Quality Improvement Program (2005-2011, n = 69,169). Multivariable adjusted analyses (MVA) were performed to identify the predictors of postoperative sepsis. A composite sepsis risk score (CSRS) was constructed using the regression coefficients of predictors significant on MVA. The score was stratified into low, intermediate, and high risk, and its predictive accuracy for sepsis, septic shock, and mortality was assessed using the area under the curve analysis. Overall, 4.3% (n = 2954) of patients developed postoperative sepsis. In MVA, Black race (odds ratio [OR] = 1.30, P = 0.002), preoperative hematocrit <30 (OR = 1.40, P = 0.022), cardiopulmonary and cerebrovascular comorbidities (P < 0.010), American Society of Anesthesiologists score >3 (P < 0.05), operative time (OR = 1.002, P < 0.001), surgical approach (OR = 1.81, P < 0.001), and procedure type (P < 0.001) were significant predictors of postoperative sepsis. CSRS demonstrated favorable accuracy in predicting postoperative sepsis, septic shock, and mortality (area under the curve 0.72, 0.75, and 0.74, respectively). Furthermore, CSRS risk stratification demonstrated high concordance with sepsis rates, 1.3% in low-risk patients versus 9.7% in high-risk patients. Similarly, 30-d mortality rate varied from 0.5% to 5.5% (10-fold difference) in low-risk patients versus high-risk patients. Our study identifies the major risk factors for 30-d sepsis after MCS. These risk factors have been converted into a simple, accurate bedside sepsis risk

    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.

    24 men suffering from localized prostatic cancer undergoing radical retropubic nerve-sparing prostatectomy were investigated by the following electrophysiological methods: Bulbocavernosus reflexes elicited from the penile skin or the posterior urethra, sensory thresholds in the posterior urethra, cerebral evoked potentials after stimulation of the pudendal nerve or the posterior urethra. 15 men were examined 4-33 months postoperatively only, 5 men were examined only preoperatively and 4 men were examined both pre- and postoperatively. 10 men suffering from minor problems due to benign prostatic hyperplasia served as controls. In patients with localized cancer of the prostate, the findings did not differ from those in the control group. In the operated group the findings were pathological in a large proportion of the patients, indicating injuries both to nervous pathways running through the pelvic nerve plexus and in the pudendal nerve. The conclusions were: Localized cancer of the prostate has minimal or no risk at all of impaired functioning in the pelvic nervous pathways. Radical retropubic prostatectomy may in some cases be undertaken without any objective evidence of injury to these nervous pathways, but is often followed by findings indicating such injury. The dorsal nerve of the penis may be affected by the operation. Transcranial stimulation of the motor cortex is a useful method in the evaluation of prolonged or absent bulbocavernosus reflexes.

    A preoperative quantitative evaluation of soft tissues is helpful for planning total knee arthroplasty, in addition to the conventional clinical examinations involved in moving the knee manually. We evaluated preoperative coronal laxity with osteoarthritis in patients undergoing total knee arthroplasty by applying a force of 150 N with an arthrometer. We examined a consecutive series of 120 knees in 102 patients. The median laxity was 0° in abduction and 8° in adduction. The femorotibial angle on non-weight-bearing standard anteroposterior radiographs was 180° and correlated with both abduction (r = −0.244, p = 0.007) and adduction (r = 0.205, p = 0.025) laxity. The results of a regression analysis suggested that the femorotibial angle is helpful for estimating both laxities. Considering the many reports on how to obtain well-balanced soft tissues, stress radiographs might help to improve the preoperative planning for gaining the optimal laxity deemed appropriate by surgeons.

    Variation in the anatomical position of the inframammary fold (IMF) in women remains poorly studied. The purpose of this study was to evaluate the incidence of asymmetry between IMF locations on the chest wall of women undergoing breast augmentation and to determine breast measurements associated with IMF asymmetry. Three-dimensional imaging analysis of the breasts was performed in 111 women with micromastia, using the Vectra Imaging System(TM). The following measurements were recorded: vertical distance between right and left IMF (inter-fold distance), vertical distance between nipples (inter-nipple distance), and difference between projection of right and left breasts in anterior-posterior direction. Asymmetry between the right and left IMF positions was found in the majority of patients (95.4%), with symmetry only found in 5 patients (4.6%). In the majority of patients (60.3%), the right IMF was located inferior to the left IMF with median inter-fold distance 0.4 cm (range, 0.1, 2.1 cm). In 39 patients (35.1%), the left IMF was located inferior to the right with median inter-fold distance 0.4 cm (range, 0.1, 1.7 cm). There was strong correlation between the degree of asymmetry of IMF and asymmetry of nipple areola complex (NAC) positions (r = 0.687, P < .01). The majority of women with micromastia demonstrate asymmetry of the IMF, which correlates with asymmetry of NAC location. The authors propose a classification system based on most commonly observed IMF locations as types I (right IMF inferior to left), type II (left IMF inferior to right) and type III (both IMF located on the same level).

    This study tried to cryopreserve low numbers of spermatozoa from men undergoing infertility treatments by inserting into agarose capsules. The capsules were transferred into a drop of cryoprotectant solution and injected 3-4 motile spermatozoa that were selected by the swim-up method by conventional intracytoplasmic sperm injection. These capsules were put on a Cryotop(®) and frozen in liquid nitrogen vapor, and then submerged into liquid nitrogen and subsequently thawed and recovered. The motile spermatozoa in the capsules were counted. Eventually, we cryopreserved 2142 motile spermatozoa in 702 agarose capsules from 26 male patients and 1356 (63%) spermatozoa maintained their motility after thawing. The spermatozoa motility rates after thawing (MRAT) ranged from 20.0% (5/25) to 95.1% (58/61) among patients. The median MRAT was 68.3% (interquartile range 46.1-75.7). The total number of motile spermatozoa collected by swim-up method strongly correlated with MRAT (r = 0.746). It was possible to cryopreserve spermatozoa from male patients undergoing infertility treatment using agarose capsules. However, there were wide differences in MRAT among patients. It seems the spermatozoa from semen where there were many motile spermatozoa may have higher freezing resistance. Further studies using this method in cryptozoospermic semen, testicular and epididymal spermatozoa are required.

    Postoperative delirium is a serious complication following hip surgery in elderly patients that can adversely affect outcomes in both hip fracture and arthroplasty surgery. Recently, the incidence of hip fracture in the Medicare population was estimated at approximately 500 000 patients per year, with the majority treated surgically. The annual volume of total hip arthroplasty is nearly 450 000 patients and is projected to increase over the next 15 to 20 years. Subsequently, the incidence of postoperative delirium will rise. The incidence of postoperative delirium after hip surgery in the elderly patients ranges between 4% and 53%, and it is identified as the most common surgical complication of older patients. The most common risk factors include advanced age, hip fracture surgery (vs elective hip surgery), and preoperative delirium/cognitive impairment. Exact pathophysiology has not been fully defined. It is hypothesized that imbalances in cortical neurotransmitters or inflammatory cytokine pathway mechanisms contribute to delirium. Development of postoperative delirium is associated with longer hospital stay, increased medical complications, and poorer short-term functional outcome. Patients who develop postoperative delirium are also at increased risk for cognitive decline beyond the acute phase. Following acute care, postoperative delirium is associated with the need for a higher level of care, an additional cost. Management of postoperative delirium centers on prevention and early recognition. Medical prophylaxis has been demonstrated to have limited utility. Utilization of delirium detection methods contributed to early recognition. The most effective means of prevention involved a multidisciplinary team focused on adequate hydration, optimization of analgesia, reduction in polypharmacy, aggressive physiotherapy, and early recognition of the delirium symptoms.

    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

    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.

    Third-space fluid shift is the mobilisation of body fluid to a non-contributory space rendering it unavailable to the circulatory system. It is a recurrent clinical phenomenon requiring swift identification to minimise deleterious effects. Nurses experience difficulties however in its early identification, diagnosis and subsequent treatment because of the lack of consensual and consistent information regarding third-spacing. This article, part II, building on the previous article, explores the clinical validly and reliability of signs and symptoms of both phases of third-space fluid shift. In addition it reinforces the use multiple patient assessment cues if nurses are to differentiate between, and accurately respond to, the various causes of both hypovolaemia and hypervolaemia. It assists nurses to increase their knowledge and uderstanding of third-space fluid shift in patients undergoing gastrointestinal surgery.

    It is important to understand the unique aspects vis-à-vis protein-energy wasting for patients undergoing PD. As a result of obligatory protein losses with the therapy, the serum albumin levels of patients undergoing PD are lower, as is the threshold serum albumin at which the risk for death is increased. Consequently, it is prudent to consider a lower threshold for serum albumin for the diagnosis of protein-energy wasting for patients undergoing PD. Likewise, it is important to consider the energy intake from obligatory nutrient absorption in the form of carbohydrates when estimating total energy intake (diet and dialysate) when evaluating patients for protein-energy wasting. The continuous nature of PD also has important therapeutic implications for protein-energy wasting. Such patients are more likely to have a complete correction of metabolic acidosis, and glucose absorption from the peritoneal dialysate has a protein-sparing effect, allowing some patients to maintain neutral nitrogen balances in the face of suboptimal protein intake. In contrast, clinical trials of amino-acid-based PD solutions have not met expectations and cannot be recommended for routine use for treatment of protein-energy wasting. In conclusion, it is important to consider these unique nutritional considerations when providing care to patients undergoing PD. Copyright © 2013 National Kidney Foundation, Inc.

    Surgical patients often show physiological and metabolic distress, muscle weakness, and long hospital stays. Physical conditioning might help recovery. We attempted to identify the most responsive measure of aerobic fitness from a four-week pre-surgical aerobic exercise program (prehabilitation) in patients undergoing major bowel resection. Twenty-one subjects randomized two to one (exercise: control) scheduled for colorectal surgery. Fourteen subjects [Body Mass Index (BMI) = 27 +/- 6 kg/m(2); maximal oxygen uptake (VO(2max)) = 22 +/- 10 ml/kg/min] underwent 3.8 +/- 1.2 weeks (27 +/- 8 sessions) of progressive, structured pre-surgical aerobic exercise training at 40 to 65% of heart rate reserve (%HRR). Peak power output was the only maximal measure that was responsive to training [26 +/- 27%, Effects Size (ES) = 0.24; Standardized Response Mean (SRM) = 1.05; p < 0.05]. For the submaximal measures, heart rate and oxygen uptake during submaximal exercise was most responsive to training (decrease by 13% +/- 15%, ES = -0.24; SRM = -0.57; and 7% +/- 6%, ES = -0.40; SRM -0.97; p < 0.05) at an exercise intensity of 76 +/- 47 W. There was no change to maximal or submaximal measures in the control group. The distance walked over six minutes improved in both groups (by approximately 30 m), but the effect size and t-statistic were higher in the exercise group. Heart rate and oxygen uptake during submaximal exercise, and peak power output are the most responsive measures to four weeks of prehabilitation in subjects with low initial fitness.

    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.

    The incidence of postoperative acute kidney injury (AKI) in patients undergoing cardiac surgery ranges from 7.7% to 28.1% in different studies, probably in relation to the criteria adopted to define AKI. AKI markedly increases mortality risk. However, despite the development of less invasive techniques, cardiac surgery remains the first option in many conditions such as severe coronary artery disease, valve diseases and complex interventions. The risk of postsurgery AKI can be reduced by adopting less invasive approaches, such as off-pump coronary artery bypass grafting or transcatheter aortic valve implantation, but these options cannot be employed in all cases. Thus, since traditional cardiac surgery remains the only option in many cases, it is important to adopt strategies helping the clinician to prevent AKI or diagnose it early. Old age, preprocedural chronic kidney disease, obesity, some comorbidities, wide pulse pressure and some pharmacological regimens represent risk factors for postsurgery AKI and mortality. Important intraoperative factor are use and duration of cardiopulmonary bypass. Postoperative efforts should be aimed toward maximizing cardiac output, avoiding drugs vasoconstricting the renal artery, providing adequate crystalloid infusion and alkalinizing urine. Fluid management should not be based on the measurements for cardiac filling pressures, which are mostly unreliable in these patients. Novel biomarkers such as cystatin C, kidney injury molecule-1 and human neutrophil gelatinase-associated lipocalin have been found to change earlier than creatinine, particularly when measured in combination, so their use in clinical practice can facilitate early diagnosis and treatment of AKI. The occurrence of oliguria despite adequate cardiovascular therapy can be managed with furosemide, possibly using continuous infusion, or renal replacement therapy.

    To explore the incidence and risk factors of blighted ovum in subfertile patients undergoing assisted reproductive technology (ART). This retrospective analysis was conducted among 2378 patients who were pregnant following embryo transfer at our center from January, 2012 to December, 2015, including cases of early pregnancy losses and simultaneous live births. The cases with early pregnancy losses were divided into embryonic pregnancy and blighted ovum groups based on the presence or absence of an embryonic pole before dilation and curettage. The clinical data of the 3 groups were analyzed for comparisons of the maternal age, paternal age, BMI, AFC, basal FSH, bFSH/bLH, duration of infertility, Gn dosage, Gn days, serum estradiol on the day of HCG administration, endometrium thickness, number of oocyte retrieved, proportion of high-quality embryos transferred, serum β-HCG value on the 10th to 14th days of embryo transfer, infertility type and miscarriage times. The incidences of blighted ovum were compared between cases with different cycles, embryo stages, infertile factors and methods of fertilization. Maternal age and paternal age, BMI, duration of infertility, infertility type and miscarriage times differed significantly between cases with blighted ovum and those with live births. Serum β-HCG level was the lowest in blighted ovum group followed by embryonic pregnancy group and then by live birth group. Blastocyst transfer was associated with a significantly higher incidence of blighted ovum as compared with cleavage embryo transfer (11.6% vs 5.6%, P=0.000). No significant difference was found in the other parameters among the 3 groups (P>0.05). Adjusted logistic regression analysis showed that maternal age, β-HCG level and blastocyst transfer were risk factors of blighted ovum. Advanced maternal age, low β-HCG level and blastocyst transfer may increase the risk of blighted ovum possibly in association with gene imprinting errors during the early stage of

In random-effects meta-analyses, only the effect on bacteriaemia remained significant. Overall mortality was not reduced (RR 1.33, 95% CI 0.32 to 5.44). If one selects patients in whom the ERCP resolved the biliary obstruction at the first procedure, there seem to be no significant benefit in using prophylactic antibiotics to prevent cholangitis (RR 0.98, 95% CI 0.35 to 2.69, only three trials). Prophylactic antibiotics reduce bacteriaemia and seem to prevent cholangitis and septicaemia in patients undergoing elective ERCP. In the subgroup of patients with uncomplicated ERCP, the effect of antibiotics may be less evident. Further research is required to determine whether antibiotics can be given during or after an ERCP if it becomes apparent that biliary obstruction cannot be relieved during that procedure.

    ABSTRACT Objective: To compare ideal PaO2 with PaO2 found, ideal PaO2/FiO2 of room air with the one found, and ideal FiO2 with FiO2 found in mechanically ventilated elderly patients. Methods: Cross-sectional study that evaluated elderly mechanically ventilated patients for at least 72 hours and who underwent three subsequent blood gas analyses. Results: The sample consisted of 48 elderly with mean age of 74.77±9.36 years. There was a significant difference between the ideal PaO2 and the one found (p<0.001), between FiO2 corrected and the offered one, and also between ideal PaO2/FiO2 of room air and the PaO2/FiO2 found (p<0,001). Conclusion: A significant increase was seen in PaO2 and FiO2 and in alterations of gas exchange by PaO2/FiO2 index than those found in normal parameters. PMID:24488386

    In hypertensive patients with target organ damage the search for possible etiologic factors may be particularly relevant. To evaluate renal symmetry, differential renal uptake of thallium-201 was quantified on renal images at 30 mins to 3 h after tracer injection in 112 hypertensive patients undergoing myocardial perfusion scintigraphy for chest pain. In some patients, renal angiographic status was known at the time of thallium-201 scintigraphy (n = 10), or disease was highly suspected (failed angioplasty, n = 6); the remainder (n = 96) were 'screened' for renovascular disease by renal thallium-201 imaging; 32 normotensive patients with no history of renal disease served as controls. Validation of thallium-201 renal imaging was obtained in a total of 17 hypertensive patients who had correlating contrast angiography, confirming eight cases of unilateral or asymmetric bilateral renovascular disease. Renography with technetium-99m DTPA was performed in 28 patients; differential renal function according to this modality correlated well with differential renal uptake of thallium-201 (r = 0.98). Of the screened hypertensives, eight had marked asymmetry of differential renal uptake and eight had possibly significant asymmetry. Renal thallium-201 imaging provided the first evidence of asymmetric renal perfusion in four cases subsequently confirmed by abdominal angiography. In addition, four post angioplasty cases had persistent or progressive asymmetry of renal perfusion disclosed by this technique. Thus, ancillary renal imaging with thallium-201 can be used to identify hypertensive patients who should be considered for renal angiographic evaluation.

    Minimal research has evaluated the renal safety of emergent computed tomography angiography (CTA) procedures, consecutive contrast medium application, and the long-term outcome in acute stroke patients. We investigated the incidence of contrast-induced renal impairment in these populations. We retrospectively reviewed patients with acute stroke syndrome who received a CTA of the brain with or without the neck within 24 hours from onset of symptoms. All creatinine results and additional conventional angiography findings were recorded. With a positive history of renal disease, contrast administration was delayed until creatinine results were available. Radiocontrast nephropathy (RCN) was defined as a >/=25% increase in serum creatinine from the baseline value up to 5 days after CTA. Four hundred eighty-one patients were reviewed, and 224 met the inclusion criteria. There were 7 of 224 (3%) who fulfilled the criteria for RCN. A number of patients underwent emergent CTA without knowledge of their creatinine value; 2 of 93 (2%) developed RCN. There were 36 patients who received an additional digital subtraction angiogram, and none of these developed subsequent RCN. No patients required dialysis, and 9 of 68 (13%) had a >25% increase in their creatinine levels at a late (>30 days) follow-up. Overall, these results illustrate that there is a low incidence of RCN in acute stroke patients undergoing emergency CTA.

    Degenerative aortic stenosis (AS) is the most frequent form of acquired valvular heart disease. AS is known to entail endothelial dysfunction caused by increased mechanical shear stress leading to elevated circulatory levels of microparticles. Endothelial and platelet microparticles (EMP and PMP) are small vesicles that originate from activated cells and thrombocytes. We sought to evaluate whether transcatheter aortic valve implantation (TAVI) procedure would elicit effects on circulating EMP and PMP. 92 patients undergoing TAVI procedure for severe AS were included in this study. Samples were obtained at each visit before TAVI, 1 week post-procedure and at 1, 3 and after 6 months after TAVI and were evaluated using flow cytometry. A 12 month clinical follow-up was also performed. CD62E+ EMP concentration before TAVI was 21.11 % (±6.6 % SD) and declined to 20.99 % (±6.8 % SD) after 1 week, to 16.63 % (±5.4 % SD, p < 0.0001) after 1 month, to 17.08 % (±4.6 % SD, p < 0.0001) after 3 months and to 15.94 % (±5.4 % SD, p < 0.0001) after 6 months. CD31+/CD42b-, CD31+/Annexin+/- EMP remained unchanged. CD31+/CD41b+ PMP evidenced a slight, but statistically significant increase after TAVI and remained elevated during the entire follow-up. Apart from a procedure-related improvement in echocardiographic parameters, TAVI procedure led also to a decline in CD62E+ EMP. The reduction in pressure gradients with less hemodynamic shear stress seems also to have beneficially affected endothelial homeostasis.

    Although several studies have documented adverse outcomes for vancomycin-resistant Enterococcus (VRE) colonization and infection in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients, data are inadequate for patients undergoing autologous (auto-)HSCT. We conducted a retrospective cohort study of 300 consecutive patients receiving an auto-HSCT between 2006 and 2014. Patients had stool cultures for VRE on admission and weekly during hospitalization. Thirty-six percent of patients had VRE gastrointestinal (GI) colonization and 3% developed a VRE bloodstream infection (BSI), all of whom were colonized. VRE strain typing of BSI isolates showed that some patients shared identical patterns. Rates of colonization and BSI in colonized patients were similar to simultaneous patients undergoing allo-HSCT, except that the latter had a higher rate of colonization at admission. A diagnosis of lymphoma was associated with an increased risk of colonization. VRE BSI was associated with longer lengths of stay and possibly higher costs, but no decrease in overall survival, and colonized patients had no VRE infections during the year following discharge. Repeat stool cultures in patients subsequently undergoing allo-HSCT suggested that most, if not all, VRE-positive auto-HSCT patients lose their detectable GI colonization within a few months of discharge. VRE colonization is frequent but carries a low risk for infection in patients undergoing auto-HSCT. However, these patients can serve as reservoirs for transmission to higher risk patients. Moreover, patients may remain colonized if proceeding to an allo-HSCT shortly after auto-HSCT, potentially increasing the risk of the allogeneic procedure. © 2015 John Wiley & Sons A/S.

    OBJECTIVE In this analysis the authors compare the characteristics of smokers to nonsmokers using demographic, socioeconomic, and comorbidity variables. They also investigate which of these characteristics are most strongly associated with smoking status. Finally, the authors investigate whether the association between known patient risk factors and disability outcome is differentially modified by patient smoking status for those who have undergone surgery for lumbar degeneration. METHODS A total of 7547 patients undergoing degenerative lumbar surgery were entered into a prospective multicenter registry (Quality Outcomes Database [QOD]). A retrospective analysis of the prospectively collected data was conducted. Patients were dichotomized as smokers (current smokers) and nonsmokers. Multivariable logistic regression analysis fitted for patient smoking status and subsequent measurement of variable importance was performed to identify the strongest patient characteristics associated with smoking status. Multivariable linear regression models fitted for 12-month Oswestry Disability Index (ODI) scores in subsets of smokers and nonsmokers was performed to investigate whether differential effects of risk factors by smoking status might be present. RESULTS In total, 18% (n = 1365) of patients were smokers and 82% (n = 6182) were nonsmokers. In a multivariable logistic regression analysis, the factors significantly associated with patients' smoking status were sex (p < 0.0001), age (p < 0.0001), body mass index (p < 0.0001), educational status (p < 0.0001), insurance status (p < 0.001), and employment/occupation (p = 0.0024). Patients with diabetes had lowers odds of being a smoker (p = 0.0008), while patients with coronary artery disease had greater odds of being a smoker (p = 0.044). Patients' propensity for smoking was also significantly associated with higher American Society of Anesthesiologists (ASA) class (p < 0.0001), anterior-alone surgical approach (p = 0

    This study aimed to describe the incidence and periprocedural predictors of permanent work disability (PWD) pension among patients ≤50 years old who underwent percutaneous coronary intervention (PCI). Patient records of 910 consecutive patients undergoing PCI at four Finnish hospitals in 2002-2012 were reviewed for baseline and procedural data and late adverse events. Data on permanent work disability (PWD) pension allocation were acquired from the Finnish Centre for Pensions, which governs the statutory pension security in Finland. Mean follow-up was 41 [standard deviation (SD) 31] months. Altogether 103/910 (11.3%) of patients were on PWD by the end of follow-up, 60 (58.3%) for cardiac diagnoses (cumulative freedom from PWD 81% at 7 years). Independent predictors of PWD were post procedural stroke [hazard ratio (HR) 4.7, 95% confidence interval (95% CI) 1.8-11.9], post procedural myocardial infarction (MI) (HR 3.3, 95% CI 1.8-6.0), diabetes (HR 2.0, 95% CI 1.1-3.7), discharge diuretics (HR 3.5, 95% CI 2.1-5.9), and increasing age (HR 1.2, 95% CI 1.1-1.3). Predictors of PWD for cardiac diagnoses were post procedural stroke and MI, discharge diuretics, and use of calcium-channel blockers, diabetes and older age. Patients ≤50 years old undergoing PCI are at a high risk for subsequent permanent disability for cardiac diagnoses. This finding underscores the need for reinforcing adherence to secondary prevention by cardiac rehabilitation and early collaboration with occupational health care professionals.

    Operations on structures in the chest (usually the lungs) involve cutting between the ribs (thoracotomy). Severe post-thoracotomy pain can result from pleural (lung lining) and muscular damage, costovertebral joint (ribcage) disruption and intercostal nerve (nerves that run along the ribs) damage during surgery. Poor pain relief after surgery can impede recovery and increase the risks of developing complications such as lung collapse, chest infections and blood clots due to ineffective breathing and clearing of secretions. Effective management of acute pain following thoracotomy may prevent these complications and reduce the likelihood of developing chronic pain. A multi-modal approach to analgesia is widely employed by thoracic anaesthetists using a combination of regional anaesthetic blockade and systemic analgesia, with both non-opioid and opioid medications and local anaesthesia blockade.There is some evidence that blocking the nerves as they emerge from the spinal column (paravertebral block, PVB) may be associated with a lower risk of major complications in thoracic surgery but the majority of thoracic anaesthetists still prefer to use a thoracic epidural blockade (TEB) as analgesia for their patients undergoing thoracotomy. In order to bring about a change in practice, anaesthetists need a review that evaluates the risk of all major complications associated with thoracic epidural and paravertebral block in thoracotomy. To compare the two regional techniques of TEB and PVB in adults undergoing elective thoracotomy with respect to:1. analgesic efficacy;2. the incidence of major complications (including mortality);3. the incidence of minor complications;4. length of hospital stay;5. cost effectiveness. We searched for studies in the Cochrane Central Register of Controlled Trials (CENTRAL 2013, Issue 9); MEDLINE via Ovid (1966 to 16 October 2013); EMBASE via Ovid (1980 to 16 October 2013); CINAHL via EBSCO host (1982 to 16 October 2013); and reference lists of

    Shoulder arthroscopy is very commonly associated with postoperative leakage of irrigation fluid. This causes apprehension to patients and their relatives and leads to frequent change of dressings. We describe a simple and effective diaper dressing for patients undergoing arthroscopic shoulder surgery. It is highly absorbent, cost-effective, and easy to apply. We have used this dressing successfully in more than 1,500 shoulder arthroscopies over the last 3 years with no adverse reaction.

    In a previous study we tried to assess the clinical usefulness of platelet count (PlC) to confirm whether postoperative pulmonary embolism could be suspected early. Unexpectedly, the 19 patients who subsequently developed pulmonary embolism had significantly lower mean PlC levels even before surgery. In an attempt to discover whether the preoperative PlC levels were associated with a different incidence of postoperative blood loss, we decided to retrospectively study the relationship between preoperative PlC levels and the consequences of blood loss. There were 459 consecutive patients undergoing hip surgery. After excluding 5 patients who died during the first 3 postoperative days, and 16 patients who bled from a definitive anatomic site, there were 438 patients. Blood loss was considered to be excessive when two or more of the following conditions were present: (1) total transfusion requirements exceeding 1,000 ml whole blood or 2 units of packed red cells; (2) a drop in hemoglobin level of 5 g/dl or more, and (3) a hemoglobin level below 8 g/dl at any moment during the first 8 postoperative days. Blood loss was considered to be excessive in 91 patients. Preoperative PlC levels were significantly lower in these patients as compared to patients without the condition (204 +/- 52 vs. 236 +/- 79 x 10(9) liter-1; p = 0.0002). When patients were classified according to the quartiles of preoperative PlC, the odds ratio of developing excessive blood loss was 0.69 (95% CI: 0.38-1.26) in patients in the second quartile; 0.57 (95% CI: 0.30-1.06) in the third quartile, and 0.27 (95% CI: 0.13-0.57) in patients in the highest quartile. After adjusting for age, sex, type of surgery and type of prophylaxis, the preoperative PlC levels maintained a statistically significant inverse correlation with postoperative blood loss.

    Introduction Some patients undergoing total joint arthroplasty are at increased risk for venous thromboembolism (VTE). The aim of the present study was to evaluate the safety and efficacy of prIVCF in preventing PE in patients undergoing joint replacement surgery who are at high-risk for VTE. Materials and Methods In this prospective, IRB-approved study, prIVCF were placed in consecutive patients who met specific high-risk criteria (history of VTE or hypercoaguable state) prior to total joint arthroplasty. Patients were followed until the IVC filter was removed. Outcomes and complications were recorded per Society of Interventional Radiology guidelines. Results One hundred and nine potentially retrievable IVC filters were placed in 105 patients, who all subsequently underwent joint arthroplasty. One hundred eight IVC filters (98.9%) were retrieved successfully in a mean time of 44.1 days (range 13-183 days). There was 1 failed IVC filter retrieval attempt (0.9%) at 46 days post implantation. Two patients (1.9%) presented with recurrent PE and were successfully treated with anticoagulation prior to IVC filter retrieval. There were no fatalities from perioperative PE. In 1 patient (0.9%), a fractured filter leg had embolized during retrieval. Conclusion Potentially retrievable IVC filters are safe and effective for prophylaxis against PE in patients at high-risk for VTE undergoing joint arthroplasty. PMID:26816965

    The Fassier-Duval (FD) rod is a stainless-steel device widely used to correct bone deformities and reduce the risk of fractures in patients with osteogenesis imperfecta (OI). Since these are telescopic expandable rods, there has been a reluctance to perform magnetic resonance imaging (MRI) in patients with OI secondary to a theoretical risk of migration during the MRI scans. The primary aim of this study was to assess the risk of migration of FD rods in patients who underwent MRI of the spine. The secondary aims are to assess the heating effects and artifact of these implants. We retrospectively reviewed our database for all patients with OI who had undergone FD rodding and subsequent MRI evaluation for craniofacial and spinal disorders. Ten patients were eligible to be included in the study. The MRI examination was performed in all patients using a1.5 T magnet. The radiographic images pre-MRI and post-MRI were evaluated and compared to assess whether or not migration of implants had occurred. Patients' charts and MRI logbooks were reviewed to assess the heating effects based on patient-reported events during or immediately after the MRI. In addition, the scans were reviewed to evaluate peri-implant soft tissues to assess for changes that might indicate such effect. Artifact was judged to be present if it interfered with the evaluation of any portion of spinal anatomy of clinical interest. Ten patients underwent 19 FD roddings. The indications for MRI in these patients were basilar invagination, basilar impression, platybasia, and complex scoliosis. None of the implants have shown any migration, heating effect, or artifact. FD rods are safe and pose no risk of migration, heating effects, or artifact when undergoing an MRI of the spine using a 1.5 T magnet. With the introduction of magnet strengths higher than 1.5 T, further testing should be performed. Level IV.

    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.

    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.

    The prevalence of patients suffering from hypoxic brain damage is increasing. Long-term outcome data and prognostic factors for either poor or good outcome are lacking. This retrospective study included 93 patients with hypoxic brain damage undergoing neurological early rehabilitation [length of stay: 108.5 (81.9) days]. Clinical data, validated outcome scales (e.g. Barthel Index-BI, Early Rehabilitation Index-ERI, Glasgow Coma Scale-GCS, Coma Remission Scale-CRS), neuroimaging data, electroencephalography (EEG) and evoked potentials were analyzed. 75.3% had a poor outcome (defined as BI <50). 38 (40.9%) patients were discharged to a nursing care facility, 21 (22.6%) to subsequent rehabilitation, 17 (18.3%) returned home, 9 (9.7%) needed further acute-care hospital treatment and 8 (8.6%) died. Barthel Index on admission as well as coma length were strong predictors of outcome from hypoxic brain damage. In addition, duration of vegetative instability, prolongation of wave III in visual evoked potentials (flash VEP), theta and delta rhythm in EEG, ERI, GCS and CRS on admission were related to poor outcome. All patients with bilateral hypodensities of the basal ganglia belonged to the poor outcome group. Age had no independent influence on functional status at discharge. As with other studies on neurological rehabilitation, functional status on admission turned out to be a strong predictor of outcome from hypoxic brain damage.

    Objectives: The objectives of this study were to evaluate the effect of radiotherapy (RT) on sexual function in patients undergoing oncologic resection for rectal cancer, and to develop a mathematical model for quantifying the risk of sexual dysfunction through time for this group of patients. Methods: Data were prospectively collected on patients undergoing proctosigmoidectomy (group 1: n = 101) or adjuvant radiotherapy (40–50 Gy) and resection (group 2: n = 100) for rectal cancer at a tertiary referral center between December 1998 and July 2004. Study end points were recorded at 7 time intervals (preoperatively, 4 months, 8 months, 1 year, 2 years, 3 years, and 4 years after surgery) and included: 1) ability to have an erection, 2) maintain an erection, 3) attain orgasm, 4) dry orgasm, and 5) whether they were sexually active. Multilevel logistic regression analysis for repeated measures was used to identify factors associated with the sexual dysfunction. A predictive model was developed and internally validated by comparing observed and model-predicted outcomes. Results: Radiotherapy had an adverse effect on the ability to get an erection, maintain an erection, attain orgasm, and being sexually active in comparison with patients undergoing surgery alone (7.4%, 12.6%, 16.2%, and 13.7% reduction 8 months after surgery respectively; P < 0.05). The effect of sexual dysfunction deteriorated with age (odds ratio for erectile function, 0.40 per 10-year increase in age; 95% confidence interval, 0.29–0.49; P < 0.001). A significant variability in sexual function was present among the 7 time points with a maximal deterioration occurring at 8 months after surgery with subsequent slow but not complete recovery (P < 0.001). The predictive model showed adequate discrimination on 4 of the 5 domains of sexual dysfunction (area under the receiver operating characteristic curve >0.70). Conclusions: Radiotherapy has an adverse effect on sexual function, the effect being

    Using data from ARISTOTLE, we describe the periprocedural management of anticoagulation and rates of subsequent clinical outcomes among patients chronically anticoagulated with warfarin or apixaban. We recorded whether (and for how long) anticoagulant therapy was interrupted preprocedure, whether bridging therapy was used, and the proportion of patients who experienced important clinical outcomes during the 30 days postprocedure. Of 10 674 procedures performed during follow-up in 5924 patients, 9260 were included in this analysis. Anticoagulant treatment was not interrupted preprocedure 37.5% of the time. During the 30 days postprocedure, stroke or systemic embolism occurred after 16/4624 (0.35%) procedures among apixaban-treated patients and 26/4530 (0.57%) procedures among warfarin-treated patients (odds ratio [OR] 0.601; 95% confidence interval [CI] 0.322-1.120). Major bleeding occurred in 74/4560 (1.62%) procedures in the apixaban arm and 86/4454 (1.93%) in the warfarin arm (OR 0.846; 95% CI 0.614-1.166). The risk of death was similar with apixaban (54/4624 [1.17%]) and warfarin (49/4530 [1.08%]) (OR 1.082; 95% CI 0.733-1.598). Among patients in ARISTOTLE, the 30-day postprocedure stroke, death, and major bleeding rates were low and similar in apixaban- and warfarin-treated patients, regardless of whether anticoagulation was stopped beforehand. Our findings suggest that many patients on chronic anticoagulation can safely undergo procedures; some will not require a preprocedure interruption of anticoagulation. ARISTOTLE was registered at www.clinicaltrials.gov as #NCT00412984. PMID:25320240

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

    Background 0.6–12.7% of patients with primary cutaneous melanoma will develop additional melanomas. Pathologic features of tumors in patients with multiple primary cutaneous melanomas have not been well described. In this large international multi-center case-control study, we compared the clinicopathologic features of a subsequent melanoma with the preceding (usually the first) melanoma in patients with multiple primary cutaneous melanomas, and with those of melanomas in patients with single primary cutaneous melanomas. Methods Multiple primary melanoma (cases) and single primary invasive melanoma (controls) patients from the Genes, Environment and Melanoma (GEM) study were included if their tumors were available for pathologic review and confirmed as melanoma. Clinicopathologic characteristics of invasive subsequent and first melanomas in cases and invasive single melanomas in controls were compared. Results 473 pairs comprising a subsequent and a first melanoma and 1989 single melanomas were reviewed. Forward stepwise regression modeling in 395 pairs with complete data showed that, compared to first melanomas, subsequent melanomas were: more commonly contiguous with a dysplastic nevus; more prevalent on the head/neck and legs than other sites; and thinner. Compared with single primary melanomas, subsequent melanomas were also more likely to be: associated with a contiguous dysplastic nevus; more prevalent on the head/neck and legs; and thinner. The same differences were observed when subsequent melanomas were compared with single melanomas. First melanomas were more likely than single melanomas to have associated solar elastosis and no observed mitoses. Conclusions Thinner subsequent than first melanomas suggest earlier diagnosis, perhaps due to closer clinical scrutiny. The association of subsequent melanomas with dysplastic nevi is consistent with the latter being risk factors or risk markers for melanoma. PMID:21913010

    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.

    2015-01-01

    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

    Dose requirements of thiopental depend on patient characteristics and infusion rate. We determined thiopental dose requirements for induction of anaesthesia, and the effects of remifentanil on cardiovascular and bispectral index (BIS) responses to tracheal intubation in spinal cord-injured (SCI) patients undergoing general anaesthesia. Twenty patients with traumatic complete SCI undergoing elective surgery were enrolled. Twenty patients without SCI served as control. Anaesthesia was induced with thiopental, followed by remifentanil 1 μg/kg and rocuronium 0.8 mg/kg, and maintained with 2% sevoflurane and 50% nitrous oxide in oxygen after tracheal intubation. Thiopental was administered at a rate of 50 mg/15 s until abolition of the eyelash reflex. Thiopental doses, BIS values, systolic arterial blood pressure (SAP), heart rate (HR) and plasma catecholamine concentrations were measured. Total thiopental dose required to abolish the eyelash reflex based on total body weight (BW) (5.26 ± 0.87 vs. 3.91 ± 1.07 mg/kg, P < 0.001) or lean BW (6.56 ± 1.37 vs. 5.24 ± 1.36 mg/kg, P < 0.01) were significantly smaller in the SCI group than in the control. SAP was decreased by induction of anaesthesia with thiopental and remifentanil, and increased by tracheal intubation in both groups. However, the peak SAP after intubation was smaller in the SCI patients. HR increased significantly above baseline values following intubation in both groups with no significant intergroup differences. Hypertension was more frequent in the control group. Norepinephrine concentrations remained unaltered following intubation in both groups. These results suggest that the dose requirements of thiopental for induction of general anaesthesia and subsequent tracheal intubation are reduced in the SCI patients. © 2012 The Authors.

    Headache is among most frequently encountered neurological symptom during hemodialysis (HD), but still under investigated in peritoneal dialysis (PD) patients. The aim of this study was to assess the incidence and clinical characteristics of dialysis headache (DH) in HD and PD patients. A total of 409 patients (91 on PD and 318 on HD) were interviewed using a structured questionnaire, designed according to the diagnostic criteria of the International Headache Classification of Headache Disorders from 2004. Patients with DH underwent a thorough neurological examination. DH was reported by 21 (6.6%) HD patients and 0 PD patients. PD patients had significantly lower serum sodium, potassium, calcium, phosphate, urea and creatinine, calcium-phosphate product, and diastolic blood pressure than HD patients. HD patients had significantly lower hemoglobin compared to PD patients. Primary renal disease was mostly parenchymal in HD patients, and vascular in PD patients. DH appeared more frequently in men, mostly during the third hour of HD. It lasted less than four hours, was bilateral, non-pulsating and without associated symptoms. Biochemical alterations may be implicated in the pathophysiology of DH. Specific features of DH might contribute to better understanding of this secondary headache disorder.

    To assess whether receipt of antibiotics by prior hospital bed occupants is associated with increased risk for CDI in subsequent patients who occupy the same bed. This is a retrospective cohort study of adult patients hospitalized in any 1 of 4 facilities between 2010 and 2015. Patients were excluded if they had recent CDI, developed CDI within 48 hours of admission, had inadequate follow-up time, or if their prior bed occupant was in the bed for less than 24 hours. The primary exposure was receipt of non-CDI antibiotics by the prior bed occupant and the primary outcome was incident CDI in the subsequent patient to occupy the same bed. Incident CDI was defined as a positive result from a stool polymerase chain reaction for the C difficile toxin B gene followed by treatment for CDI. Demographics, comorbidities, laboratory data, and medication exposures are reported. Among 100 615 pairs of patients who sequentially occupied a given hospital bed, there were 576 pairs (0.57%) in which subsequent patients developed CDI. Receipt of antibiotics in prior patients was significantly associated with incident CDI in subsequent patients (log-rank P < .01). This relationship remained unchanged after adjusting for factors known to influence risk for CDI including receipt of antibiotics by the subsequent patient (adjusted hazard ratio [aHR], 1.22; 95% CI, 1.02-1.45) and also after excluding 1497 patient pairs among whom the prior patients developed CDI (aHR, 1.20; 95% CI, 1.01-1.43). Aside from antibiotics, no other factors related to the prior bed occupants were associated with increased risk for CDI in subsequent patients. Receipt of antibiotics by prior bed occupants was associated with increased risk for CDI in subsequent patients. Antibiotics can directly affect risk for CDI in patients who do not themselves receive antibiotics.

    The purpose of this study was to evaluate dental anxiety in patients undergoing apicectomy procedures performed with conventional instruments or an erbium-doped yttrium aluminum garnet (Er:YAG) laser. Twenty-eight patients undergoing apicectomy were divided into two groups; roots were removed with an Er:YAG laser in group A (n=14) and with conventional instruments in group B (n=14). All patients completed preoperative State-Trait Anxiety Inventories (STAI) and postoperative questionnaires. Although state anxiety, trait anxiety, and postoperative questionnaire scores were lower in patients undergoing Er:YAG laser treatment than in those treated with conventional instruments, the differences were not statistically significant. Surgical instruments affect the anxiety levels of dental patients. Even with the STAI scores being lower for patients treated with Er:YAG, use of the Er:YAG laser alone cannot contribute to the resolution of dental anxiety. A patient's individual condition is the major factor influencing that patient's anxiety level.

    We studied the influence of music on stress reaction of patients during cerebral angiography. We randomised 30 patients to a music or a control group. We measured stress hormones, blood pressure, heart rate and psychological parameters. Patients examined without music showed rising levels of cortisol in plasma, indicating high stress levels, while cortisol in patients examined with music remained stable. Systolic blood pressure was significantly lower listening to music. Patients with a high level of fear did appear to benefit particularly from the music.

    Background: Obesity has become epidemic, and is associated with greater morbidity and mortality. Treatment is multidisciplinary. Surgical treatment is a consistent resource in severe obesity. The indication of preoperative upper gastrointestinal endoscopy in asymptomatic patients is controversial; however, most studies recommend its implementation in all patients. Aim: To analyze endoscopic performance in patients who were in preoperative for bariatric surgery and compare them with control group. Method: A series of 35 obese patients in preoperative period for bariatric surgery compared with a control group of 30 patients submitted to upper endoscopy. There were analyzed clinical and endoscopic data. Results: The mean age of the group of patients was 43.54 years. Most individuals in the group of patients were female with median BMI of 47.26kg/m2and in control group 24.21 kg/m2. The majority of patients were asymptomatic. Upper endoscopy was altered in 81.25% of asymptomatic patients. Endoscopic findings in the patient group were 57.1% resulting from peptic ulcer disease and 34.3% associated with GERD. The analysis of endoscopic findings in patients showed no significant difference in relation of the control group. The prevalence of H. pylori infection was 60% in patients. Conclusion: It is recommended that the upper endoscopy should be made in all patients in the preoperative bariatric surgery period, although the degree of obesity is not related to a greater number of endoscopic findings. Obese patients do not have more endoscopic findings that non-obese individuals. PMID:26537272

    To assess the outcome of patients treated conservatively vs surgically during their first admission for sigmoid volvulus. We conducted a retrospective study of 61 patients admitted to Aarhus University Hospital in Denmark between 1996 and 2011 for their first incidence of sigmoid volvulus. The condition was diagnosed by radiography, sigmoidoscopy or surgery. Patients treated with surgery underwent either a sigmoid resection or a percutaneous endoscopic colostomy (PEC). Conservatively treated patients were managed without surgery. Data was recorded into a Microsoft Access database and calculations were performed with Microsoft Excel. Kaplan-Meier plotting and Mantel-Cox (log-rank) testing were performed using GraphPad Prism software. Mortality was defined as death within 30 d after intervention or surgery. Among the total 61 patients, 4 underwent emergency surgery, 55 underwent endoscopy, 1 experienced resolution of the volvulus after contrast enema, and 1 died without treatment because of large bowel perforation. Following emergency treatment, 28 patients underwent sigmoid resection (semi-elective n = 18; elective n = 10). Two patients who were unfit for surgery underwent PEC and both died, 1 after 36 d and the other after 9 mo, respectively. The remaining 26 patients were managed conservatively without sigmoid resection. Patients treated conservatively on their first admission had a poorer survival rate than patients treated surgically on their first admission (95%CI: 3.67-14.37, P = 0.036). Sixty-three percent of the 26 conservatively treated patients had not experienced a recurrence 3 mo after treatment, but that number dropped to 24% 2 years after treatment. Eight of the 14 patients with recurrence after conservative treatment had surgery with no 30-d mortality. Surgically-treated sigmoid volvulus patients had a higher long-term survival rate than conservatively managed patients, indicating a benefit of surgical resection or PEC insertion if feasible.

    Anti-vascular endothelial growth factor (VEGF) medication, injected intravitreally, is currently the standard of care in patients with different retinal pathologies. Since its introduction in 2006, an increasing number of patients have undergone this procedure in Ghent University Hospital. Strikingly, more patients were diagnosed with contact dermatitis caused by ophthalmic products used during intravitreal injection procedure. To identify which of the substances used during intravitreal injection is most likely to cause contact dermatitis. Sixteen patients who developed a burning and stinging sensation and swelling of the eyelids after intravitreal injection were tested. All patients were patch tested with the Belgian baseline series, as well as a cosmetic, a pharmaceutical and an ophthalmic series, including the different eye drops used during the intravitreal injection procedure. Fourteen of 16 patients reacted to at least one of the substances used during the injection procedure. Nine patients reacted to phenylephrine (56%), 5 to iso-Betadine(®) ophthalmic solution (31%), and 3 patients to sodium metabisulfite (16%). The most common causal allergen was phenylephrine, being positive in 56% of patients. Patients most likely become sensitized because of the high frequency of usage of phenylephrine during repeated intravitreal injections and follow-up consultations. © 2015 John Wiley & Sons A/S.

    Postoperative acute urinary retention was evaluated in the patients who underwent Pereyra procedure. Comparison of suprapubic and urethral catheterization. Between January 1994 and July 1995, fifty two patients with urinary stress incontinence underwent Pereyra procedure, 31 female patient with suprapubic drainage (cistofix Ch 15) and 17 urethral catherization with a latex foley catheter. Sponatneous micturition and urinary retention was evaluated until the catheter was removed. Mean age was 43.8 years (32 a 66), the duration of suprapubic vesical drainage with suprapubic catheter were 3 days in 58.6% of the patients, and more than 3 days in 41.29%. Recatheterizacion in the patients with urethral drainage was more frequent. Urinary retention after 7 days was present in 23.99% with suprapubic vesical drainage and 28.5% with urethral catheter. Recatheterization is more frequent in patients with urethral catheter.

    Approximately 4.2 million patients in the United States are taking warfarin, making it the 11th most prescribed drug. Warfarin is primarily used for treatment of venous thromboembolic disease and stroke prevention in patients with atrial fibrillation and mechanical heart valves. Dentists frequently encounter anticoagulated patients and are faced with management decisions in these patients who require dental procedures. Observational studies suggest the risk of thrombosis if anticoagulation is suspended during dental procedures is higher than the risk of bleeding if anticoagulation is not suspended. Several groups now offer guidelines that recommend most minor dental procedures should be performed while on therapeutic warfarin. The recent approval of several new oral anticoagulants has introduced greater complexity to the management of the anticoagulated patient, and this narrative review will discuss current guidelines, the scientific underpinnings of the guidelines, and offer some practical suggestions for patients that are receiving the new agents.

    Our goal was to evaluate the functional outcomes following radial forearm free-flap reconstruction with a focus on radiotherapy. A 2-year prospective study was performed. A total of 47 patients were enrolled finally. They were asked to complete the swallowing, chewing, speech domains of the University of Washington Quality of Life questionnaire preoperatively and at 2 years postoperatively. Swallowing capacity was apparently affected after surgery, but no patients reported there was chokes cough during eating, the mean score was 51.1 (SD: 21.3). Most patients (70.2%) presented their articulation was good enough for everyday life, and the mean score was 60.0 (SD: 21.1). As for chewing, only 7 (14.9%) patients complained there was negative effect, and the mean score was as high as 92.6 (SD: 18.0). Compared to patients with surgery only, patients with postoperative radiotherapy only had significantly worse swallowing and speech capacity. Compared with patients with postoperative radiotherapy only, patients with both preoperative and postoperative radiotherapy tended to have better swallowing and speech. No significant differences were found between chewing and radiotherapy. In most patients, the results of swallowing, speech, and chewing are favorable. Postoperative radiotherapy has an apparent impact on functional impairment, but preoperative tends to preserve the original tongue function.

    The development of abdominal surgery represents an alternative therapy for the morbidly obese; however, patients undergoing this surgical procedure often experience postoperative pulmonary complications. The use of alveolar recruitment maneuvers and/or perioperative ventilatory strategies is a possible alternative to reduce these complications, focusing on the reduction of postoperative pulmonary complications. In this review, the benefits of perioperative ventilatory strategies and the implementation of alveolar recruitment maneuvers in obese patients undergoing abdominal surgery are described.

    The aim of this prospective study was to determine the prevalence of pre-operative atrial fibrillation and the incidence of postoperative atrial fibrillation in patients undergoing elective or emergency intracranial neurosurgical procedures and the relation to survival and neurological outcome at 6-months follow-up compared to patients with sinus rhythm. A total of 2020 patients were enrolled; 1540 patients underwent elective procedures and 480 underwent emergency procedures. Prevalence of pre-operative atrial fibrillation was 3.7% in elective and 7.2% in emergency procedures (p = 0.0012). In patients undergoing elective cerebral procedures with pre-operative atrial fibrillation, compared to patients with sinus rhythm, 6-month neurological outcome and survival rate are similar. In patients undergoing emergency neurosurgical cerebral procedures, the presence of pre-operative atrial fibrillation is related to an increased risk of poor neurological outcome but with similar survival rate.

    Background Few studies with contradictory results have been published on the safety of pelvic radiation therapy (RT) in patients with inflammatory bowel disease (IBD). Methods From 1989 to 2015, a single center retrospective analysis was performed including all IBD patients who received pelvic external beam radiation therapy (EBRT) or brachytherapy (BT) for a pelvic malignancy. Treatment characteristics, IBD activity and gastrointestinal (GI) toxicity were examined. Results Overall, 28 patients with Crohn’s disease (CD) (n=13) or ulcerative colitis (n=15) were included in the present study. Median follow-up time after irradiation was 5.9 years. Regarding IBD activity, only one and two patients experienced a severe episode within and after 6 months of follow-up, respectively. Grade 3/4 acute GI toxicity occurred in 3 (11%) patients, whereas one (3.6%) patient experienced late grade 3/4 GI toxicity. Only patients with rectal IBD location (P=0.016) or low body mass index (BMI) (P=0.012) experienced more severe IBD activity within or after 6 months following RT, respectively. Conclusions We report an acceptable tolerance of RT in IBD patients with pelvic malignancies. Specifically, a low risk of uncontrolled flare-up was observed. PMID:28280621

    This study aimed to determine the levels of depression and hopelessness of patients receiving chemotherapy. Through knowledge of the levels of hopelessness and depression in such patients, this study could contribute to the planning of nursing interventions. The study involved 101 patients with cancer who presented to the outpatient unit of a medical oncology clinic to receive outpatient chemotherapy between January and March 2006. Data on the patients' sociodemographic features, as well as their scores on the Beck Hopelessness Scale and the Beck Depression Inventory, were obtained. The patients' mean total depression score was 16.0 +/- 8.3 and their mean hopelessness score was 6.9 +/- 3.4. There was a statistically significant positive relationship between depression and hopelessness. The results indicated that depression and hopelessness were strongly and positively correlated.

    Obese patients are less likely to have cardiac surgery than normal weight patients. This could be due to physician or patient decision-making. We undertook a qualitative descriptive study to explore the influence of obesity on patients' decision-making to have cardiac surgery. Forty-seven people referred for coronary artery bypass graft (CABG) surgery were theoretically sampled. Twelve people had declined cardiac surgery. Participants underwent in-depth interviews aimed at exploring their decision-making process. Data were analyzed using conventional content analysis. Though patients' weight did not play a role in their decision, their relationship with their cardiologist/surgeon, the rapidity and orchestration of the diagnosis and treatment, appraisal of risks and benefits, previous experience with other illness or others who had cardiac surgery, and openness to other alternatives had an impact. It is possible that there is a lack of comfort or acknowledgment by all parties in discussing the influence of weight on CABG surgery risks.

    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

    2015-03-01

    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.

    The aim of this study was to determine the levels of anxiety in patients with transesophageal echocardiography (TEE). The research was carried out at a university's Heart Hospital, echocardiography laboratory between the dates of January-October 2014. Data were collected with Patient Identification Form, State and Trait Anxiety Inventory. The level of state and trait anxiety was measured by Spielberger's State-Trait Anxiety Inventory. Signed forms of consent for the study were obtained from patients after the ethics committee approval. Descriptive statistics, t-test, Kruskal-Wallis, Mann-Whitney U test and Pearson correlation coefficient were used for statistical data analysis. The study included 102 patients who were admitted to the cardiology department for TEE. The mean age of the patients was 44.12±16.86 years and 52.9% were men. About 46.5% of them graduated from primary school, 74.5% were married, and 52.0% has moderate income. Approximately half the patients reported that they had received information for TEE. State anxiety scores of patients ranged from 31 to 66 (mean±SD; 46.7±8.7), and their trait anxiety scores ranged from 28 to 52 (mean±SD; 44.4±4.3). Low educational level, female gender, and hospitalized patients' state anxiety point were very high and statistically significant. Anxiety level should be determined in this patients, and appropriate nursing care should be done for high anxiety score patients. © 2016, Wiley Periodicals, Inc.

    Objective To analyze voice function before and after thyroidectomy for patients with normal preoperative voice using a standardized multidimensional voice assessment protocol. Summary Background Data The natural history of post-thyroidectomy voice disturbances for patients with preserved laryngeal nerve function has not been systematically studied and characterized with the intent of using the data for postoperative voice rehabilitation. Methods During a prospective single-arm study, patients with normal voice underwent functional voice testing using a standardized voice grading scale and a battery of acoustic, aerodynamic, glottographic, and videostroboscopic tests before, 1 week after, and 3 months after thyroidectomy. Differences in observed sample means were evaluated using analysis of covariance or t test; categorical data was analyzed using the Fisher exact or chi-square test. Results Fifty-four patients were enrolled; 50 and 46 were evaluable at 1 week and 3 months, respectively. No patient developed recurrent laryngeal nerve injury; one had superior laryngeal nerve injury. Fifteen (30%) patients reported early subjective voice change and seven (14%) reported late (3-month) subjective voice change. Forty-two (84%) patients had significant objective change in at least one voice parameter. Six (12%) had significant alterations in more than three voice measures, of which four (67%) were symptomatic, whereas 25% with three or fewer objective changes had symptoms. Patients with persistent voice change at 3 months had an increased likelihood of multiple (more than three) early objective changes (43% vs. 7%). Early maximum phonational frequency range and vocal jitter changes from baseline were significantly associated with voice symptoms at 3 months. Conclusions Early vocal symptoms are common following thyroidectomy and persist in 14% of patients. Multiple (more than three) objective voice changes correlate with early and late postoperative symptoms. Alterations

    Thyroid disease is one of the most common endocrine conditions affecting women during reproductive age. A link between thyroid and assisted reproduction outcome is debated. Serum TSH levels, number and scoring of oocytes and embryos, and number of clinical pregnancies were retrospectively recorded in 164 women undergoing assisted reproduction technologies (ART) at an University-based fertility center, to evaluate the outcome of the first steps of assisted reproduction (ovarian stimulation, oocyte pickup and fertilization, embryo transfer and implantation) in relation to thyroid function and autoimmunity. No significant relationship was found between TSH and all parameters, except clinical pregnancy rate (22.3% in TSH ≤ 2.5 group versus 8.9% in TSH > 2.5 mUI/L group; P = 0.045). No pregnancy occurred in women with anti-thyroperoxidase autoantibodies, while pregnancy occurred in 23.9% of cycles without autoimmunity (P = 0.02). Further studies must be conducted in order to shed light on the link between infertility and thyroid dysfunction. © 2013 John Wiley & Sons Ltd.

    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.

    In patients undergoing peritoneal dialysis (PD), PD-related infection is a major cause of PD failure and hospital admission. Good air quality is required when dialysate exchange or exit site wound care is performed. To our knowledge, investigation of air pollution as a factor for PD-related infection in patients undergoing dialysis is limited. This study aimed to assess the effect of environmental particulate matter (PM) and other important risk factors on 1-year PD-related infection in patients undergoing PD.A total of 175 patients undergoing PD were recruited in this 1-year retrospective observational study. Differences in environmental PMs (PM10 and PM2.5) were analyzed with respect to the patients' living areas. The patients undergoing PD were categorized into 2 groups according to PM2.5 exposure: high (n = 61) and low (n = 114). Demographic, hematological, nutritional, inflammatory, biochemical, and dialysis-related data were analyzed. Multivariate binary logistic and multivariate Cox regression analyses were used to analyze 1-year PD-related infection.A total of 175 patients undergoing PD (50 men and 125 women) were enrolled. Thirty-five patients had PD-related infection within 1 year. Multivariate Cox regression analysis showed that high environmental PM2.5 exposure (hazard ratio (HR): 2.0, 95% confidence interval [CI] [1.03-3.91]; P = .04) and female sex (HR: 2.77, 95% CI [1.07-7.19]; P = .03) were risk factors for 1-year PD-related infection.Patients undergoing PD with high environmental PM2.5 exposure had a higher 1-year PD-related infection rate than that in those with low exposure. Therefore, air pollution may be associated with PD-related infection in such patients.

    For critically ill patients undergoing continuous renal replacement therapy (CRRT), daptomycin dosing recommendations are scarce. We, therefore, retrospectively assessed routinely measured daptomycin plasma concentrations, daptomycin dose administered and microbiological data in 11 critically ill patients with Gram-positive infections that had received daptomycin once daily. The retrospective analysis included critically ill patients treated at the intensive care unit (ICU) who had daptomycin plasma concentrations measured. Daptomycin dose ranged from 3 to 8 mg/kg/q24 h in patients undergoing CRRT (n = 7) and 6 to 10 mg/kg/q24 h in patients without CRRT (n = 4). Peak and trough concentrations showed a high intra- and inter-patient variability in both groups, independent of the dosage per kg body weight. No drug accumulation was detected in CRRT patients with once-daily daptomycin dosing. Causative pathogens were Enterococcus faecium (n = 6), coagulase-negative Staphylococcus (n = 2), Staphylococcus aureus (n = 2) and unknown in one patient. Microbiological eradication was successful in 8 of 11 patients. Two of three patients with unsuccessful microbiological eradication and fatal outcome had an Enterococcus faecium infection. In critically ill patients undergoing CRRT, daptomycin exposure with once-daily dosing was similar to ICU patients with normal renal function, but lower compared to healthy volunteers. Our data suggest that daptomycin once-daily dosing is appropriate in patients undergoing CRRT.

    Background Sexual abuse has been linked to strong effects on gastrointestinal health. Colonoscopy can provoke intense emotional reactions in patients with a sexual abuse history and may lead to avoidance of endoscopic procedures. Objective To determine whether care around colonoscopy needs adjustment for patients with sexual abuse experience, thereby exploring targets for the improvement of care around colonoscopic procedures. Methods Questionnaires were mailed to patients (n = 1419) from two centers within 11 months after colonoscopy. Differences in experience of the colonoscopy between patients with and without a sexual abuse history were assessed and patients' views regarding physicians' inquiry about sexual abuse and care around endoscopic procedures were obtained. Results A total of 768 questionnaires were analyzed. The prevalence of sexual abuse was 3.9% in male and 9.5% in female patients. Patients born in a non-western country reported more sexual abuse (14.9%) than those born in a western country (6.3%; p = 0.008). Discomfort during colonoscopy was indicated on a scale from 0 to 10, mean distress score of patients with sexual abuse was 4.8(±3.47) compared to 3.5(±3.11) in patients without a sexual abuse history (p = 0.007). Abdominal pain was a predictor for higher distress during colonoscopy (β = −0.019 (SE = 0.008); p = 0.02, as well as the number of complaints indicated as reason for colonoscopy (β = 0.738 (SE = 0.276); p = 0.008). Of patients with sexual abuse experience, 53.8% believed gastroenterologists should ask about it, 43.4% said deeper sedation during colonoscopy would diminish the distress. Conclusions Sexual abuse is prevalent in patients presenting for colonoscopy. Patients with a sexual abuse history experience more distress during the procedure and indicate that extra attention around and during colonoscopy may diminish this distress. PMID:24454784

    Fluid administration among patients undergoing liver resection is a key aspect of perioperative care. We sought to examine practice patterns of crystalloid administration, as well as potential factors associated with receipt of crystalloid fluids. Patients who underwent liver resection between 2010 and 2014 were identified. Data on clinicopathologic variables, operative details, and perioperative fluid administration were collected and analyzed using univariable and multivariable analyses; variation in practice of crystalloid administration was presented as coefficient of variation (COV). Among 487 patients, median crystalloid administered at the time of surgery was 4,000 mL. After adjusting for body size and operative duration, median corrected crystalloid was 30.0 mL kg(-1) m(2) h(-1), corresponding with a COV of 35%. Patients who received <30 mL kg(-1) m(2) h(-1) crystalloids were more likely to be younger (58 vs 60 years), white (79% vs 74%), and have a higher body mass index (BMI; 28.2 vs 25.4 kg/m(2); all P < .001). On multivariable analysis, increasing Charlson comorbidity index, BMI, estimated blood loss, and each additional hour of surgery were all associated with increased crystalloid administration (all P < .05). Corrected crystalloid administration varied among providers with a corrected COV ranging from 14% to 61%. When overall variation in crystalloid administration was assessed, 80% of the variation occurred at the patient level, and 20% occurred at the provider level (surgeon, 3% vs anesthesiologist, 17%). There was wide variability in crystalloid administration among patients undergoing liver resection. Although the majority of variation was attributable to patient factors, a large amount of residual variation was attributable to provider-level differences. Copyright © 2016 Elsevier Inc.

    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.

    We report the case of a 73-year-old man with medical diagnoses of long-standing diabetes mellitus, chronic ischemia of the lower limbs and intermittent claudication, for which the patient had been treated with minimally invasive radiological surgery. On arrival at the radiology unit, the patient had nursing diagnoses of anxiety and fear. Intraoperatively, the client had nursing diagnoses of pain, urine retention and infection risk. At discharge, a collaboration problem was detected and hemorrhagic risk. The patient received individualized nursing care. Interventions were planned following the nursing intervention classification (NIC) and the expected results for these interventions followed the Nursing Outcomes Classification (NOC) taxonomy. The application of an appropriate nursing care plan contributes to making the patient's hospital stay easier, more comfortable and less traumatic.

    Background: We evaluated the association between hemodynamic parameters of chronic congestive heart failure (CHF) and mediastinal lymphadenopathy (MLA) in heart transplantation (HT) candidates and the effect of HT on MLA. We also described the results of lymph node (LN) biopsies of MLA in the patients. Methods: Patients who underwent HT evaluation over an 8-year period and had chest CT scans were evaluated retrospectively. Data collected included LN sizes pre-HT and post-HT, echocardiographic measurements, radionuclide-derived ejection fraction, and right-sided heart catheterization hemodynamics. MLA was defined as LNs > 1 cm in smallest dimension. Results: Of 118 patients, 53 patients had MLA. MLA had weak statistically significant correlations with elevated mean pulmonary artery pressure (MPAP), mitral regurgitation (MR), tricuspid regurgitation (TR), right atrial pressure (RAP), and pulmonary capillary wedge pressure (PCWP). Thirty-six patients with MLA underwent HT, and nine of the 36 had post-HT chest CT scans. All nine patients showed a decrease in LN size post-HT (mean LN diameter pre-HT = 1.16 ± 0.137 cm, post-HT = 0.75 ± 0.32 cm). Seven of 53 patients with MLA underwent biopsies. Four had benign LNs, one had sarcoidosis, and two had lung cancer. Conclusions: MPAP, MR, TR, RAP, and PCWP had weak statistically significant correlations with MLA. HT led to regression of MLA in patients who underwent CT scans post-HT, implying that MLA is related to CHF. However, we also identified clinically important causes of MLA; therefore, biopsy should be considered if enlarged LNs fail to regress after maximal medical management of CHF. PMID:20966040

    Autologous bone marrow transplant (ABMT) represents a high metabolic stress. Glutamine has proven to be effective in severe catabolic states, although there are controversial studies. To assess the effect of parenteral nutrition (PN) therapy supplemented with glutamine on the occurrence of mucositis and mean hospital stay in patients submitted to ABMT. Retrospective study of patients submitted to ABMT between 2006 and 2009. In 2008, one vial of L-alanyl-L-glutamine (20 g) was added by protocol to the PN formulations of these patients. Thirteen clinical charts since that date (glutamine group) and 13 previous charts (control group) were randomly selected (n = 26). We compared the degree of mucositis and hospital stay in both groups. In the subgroup of glutamine-treated patients, we compare the glutamine dose in the patients developing some degree of mucositis with that of those not having this complication. Mean hospital stay: 27.8 ± 7.4 days (control group) vs. 20.3 ± 5.3 days (glutamine group) (p = 0.01). The severity of mucositis was lower in the glutaminetreated group (p = 0.02). The weight-adjusted dose of L-alanyl-L-glutamine in the patients not developing mucositis was higher than in the other ones (0.32 vs. 0.24 g/kg/day; p = 0.02). Glutamine supplementation reduces the degree of mucositis and hospital stay in patients submitted to autologous bone marrow transplantation. The degree of mucositis is lower in the subgroup of patients receiving higher doses of glutamine.

    Periodontal inflammation has been implicated in atherosclerosis and coronary heart disease (CHD). Coronary angiography (CA) is used in the assessment of CHD; only a few studies have evaluated periodontal disease (PD) and angiographic measures of coronary atherosclerosis. The aim of this study was to investigate the association between CHD and PD. In this prospective epidemiologic study, 466 patients underwent CA and were assessed for PD. All patients underwent physical, laboratory, cardiac, and dental examination including dental x-rays. Periodontal disease and coronary angiograms were evaluated blindly by a dentist and 2 cardiologists, respectively. A coronary stenosis greater than 50% was ruled as CHD. Periodontal disease was defined and measured with the Community Periodontal Index of Treatment Needs (CPITN); and if at least 2 sextants (segments dividing mandible and maxilla into 6) were recorded as having CPITN of at least 3 (signifying that sextant had periodontal pocket depth ≥ 3.5 mm), the patient was coded as having PD. Three-hundred forty-nine patients (74.9%) had CHD assessed by CA The CHD patients had PD in 55.6% vs 41.9% in the non-CHD patients (P < .01). The CPITN scores were significantly higher in patients with vs without CHD, 2.43 vs 2.16, respectively (P = .023). After adjusting for age, sex, and risk factors for atherosclerosis with additional inclusion of C-reactive protein and erythrocyte sedimentation rate, PD remained significantly related to CHD (odds ratio = 1.9; 95% confidence interval, 1.2-3.1). Other predictors for CHD were male sex, age, high-density lipoprotein cholesterol, and diabetes. Our results demonstrate an increased odds ratio for angiographically determined CHD in patients with PD and that CHD and PD may cluster in particular groups of a population. Our data indicate that PD represents a potentially modifiable risk factor that is both preventable and treatable with predictable treatments that pose negligible risk.

    This large-scale prospective cohort study of a Taiwan population applied generalized estimating equations to evaluate predictors of health-related quality of life (HRQOL) after open cholecystectomy (OC) and laparoscopic cholecystectomy (LC) procedures performed between February 2007 and November 2008. The Gastrointestinal Quality of Life Index and Short Form-36 were used in a preoperative assessment and in 3(rd) month and 6(th) month postoperative assessments of 38 OC and 259 LC patients. The HRQOL of the cholecystectomy patients were significantly improved at 3 months and 6 months postsurgery (p<0.05). At 3 months postsurgery, HRQOL improvement was significantly larger in LC patients than in OC patients. Patient characteristics, clinical characteristics, and health care quality were also significantly related to HRQOL improvement (p<0.05). Additionally, after controlling for related variables, preoperative health status was significantly and positively associated with each subscale of the Gastrointestinal Quality of Life Index and Short Form-36 throughout the 6 months (p<0.05). Patients should be advised that their postoperative HRQOL may depend not only on their postoperative health care but also on their preoperative functional status.

    Background Salivary changes in hemodialysis patients may result in various oral manifestations. This research intended to determine oral manifestations and some salivary markers in hemodialysis patients. Material and Methods This cross-sectional study was conducted on 30 hemodialysis patients (the patient group) and 30 healthy individuals (the control group). Saliva urea and calcium levels and pH values of the participants were measured, and oral manifestations such as pale mucosa, xerostomia, halitosis, changes in the sense of taste, increased calculus formation, gingival bleeding, etc. were recorded in the information collection form. The data was analyzed using T-test and chi-square, and p<0.05 was considered to be significant. Results The mean salivary urea level and pH value in the patient group were significantly higher compared to those of the control group (P<0.05), but there were no significant differences between the two groups with respect to salivary calcium. Halitosis, xerostomia, and increased calculus were the most prevalent manifestations, and gum bleeding was the least prevalent among the patients. Conclusions Advanced chronic renal insufficiency can increase salivary urea level, pH value, halitosis, xerostomia, and calculus formation, and may cause pale mucosa.

    The aim of this study was to determine the prevalence of moderate ischemic mitral regurgitation (IMR) in the contemporary CABG population. We also aimed to correlate the effective regurgitant orifice area (ERO) of any regurgitant mitral valve in patients with coronary artery disease with the semiquantitative integrated scale of IMR. From March 15 through June 15, 2006, 510 consecutive CABG patients in three tertiary centres were included in the study. All patients showing any sign of mitral regurgitation (MR) at the referring hospital underwent a preoperative transthoracic echocardiographic estimation of the degree of MR using the integrated scale (1-4) and ERO. IMR was found in 141 patients (28%). The prevalence of moderate 2+ or worse IMR was 4% (95% CI; 2.5-6.1%) and the ERO corresponding to 2+ IMR or more ranged from 5 to 30 mm(2). Fourteen patients had an ERO between 15-30 mm(2). According to our study, patients with moderate IMR, defined as an ERO between 15-30 mm(2), account for only 2.7% (95% CI; 1.5-4.7%) of a non-emergency CABG population.

    To determine whether the diagnosis of hypertensive encephalopathy (HE) is linked to an increased risk of subsequent epilepsy by using a nationwide population-based retrospective study. Our study featured a study cohort and a comparison cohort. The study cohort consisted of all patients with newly diagnosed HE between 1997 and 2010, compiled from universal insurance claims data on patients with hypertension taken from the National Health Insurance Research Database. The comparison cohort comprised the remaining hypertensive patients without encephalopathy. The follow-up period was terminated following the development of epilepsy, death, withdrawal from the National Health Insurance system, or the end of 2010. We determined the cumulative incidences and hazard ratios (HRs) of epilepsy development. The incidence of subsequent epilepsy was 2.25-fold higher in the patients with HE than in comparisons (4.17 vs. 1.85 per 1000 person-years), with an adjusted HR of 2.06 (95% CI=1.66-2.56) in the multivariable Cox proportional-hazards regression analysis. The incidence of epilepsy was higher in men, younger patients with HE, and those with brain disorders. We found that, in Taiwan, patients with HE are at an increased risk of subsequent epilepsy. Physicians should be aware of HE's link to epilepsy when assessing patients with HE. © 2013.

    An open approach has been adopted for rhinoplasty because of its wide and undistorted exposure. The formation of a columellar incision scar is the main drawback of this approach. To evaluate the incidence and evolution of and risk factors for columellar incision scars in an Asian population. A retrospective case series of 529 patients who underwent open rhinoplasty was performed in a tertiary care referral center in South Korea from January 1, 2011, to May 31, 2014. Problematic transcolumellar incision scars were categorized into wide and depressed, notching, and hyperpigmented wound types. Follow-up was complete on January 28, 2015, and data were assessed from July 1, 2014, to May 29, 2015. The incidence of each problematic scar and the time course of erythema evolution were evaluated. Factors affecting the formation of a problematic scar were also evaluated. Of 529 patients (176 female and 353 male patients; mean age, 31 [range, 5-70] years), 234 patients with at least 6 months of follow-up underwent evaluation for a problematic scar. Fourteen of the 234 patients (6.0%) had problematic incision scarring (wide and depressed wound, 4 [1.7%]; notching wound, 3 [1.3%]; hyperpigmentation, 4 [1.7%]; marginal incision hypertrophic scar, 2 [0.8%]; and columellar skin necrosis, 1 [0.4%]). Of the 243 patients with regular follow-up who underwent evaluation for erythema evolution, erythematous wounds were found in almost all in the immediate postoperative period and had normalized by a mean (SD) of 66.7 (37.4) postoperative days. Use of costal cartilage as tip graft material was associated with a problematic incision scar (2 of 25 patients [8.0%] vs 6 of 180 patients with other graft material [3.3%]; P = .02). In this cohort of Asian patients, the incisions used for an open rhinoplasty approach had some problems. However, the low incidence of problematic scars indicates that open rhinoplasty should not be discouraged because of the incision scar. 4.

    Recentry, surgical candidates have become older and have more surgical risk factors, perioperative patient management become more important than before. In the patients with significant arrhythmia observed in the preoperative period, examination of the baseline heart disease, i.e. myocardial ischemia or congestive heart failure, is mandatory and, if necessary, adequate treatment such as defibrillator, the implantation of a pacemaker, anticoagulation therapy, or other medical therapy should be performed. In the patients with atrial fibrillation, clinical prediction rules such as the congestive heart failure, hypertension, age>75, diabetes, previous stroke or transient ischemic attack (TIA) [CHADS 2] score have been developed to identify those patients at highest risk for thrombo-embolism and can be used when assessing the need for bridging anticoagulation by heparin prior to surgery. The electrical stimulus from electrocautery may inhibit demand pacemakers or may reprogram the pacemaker. An asynchronous or non-sensing pacemaker mode is recommended in patients who are pacemaker dependent and whose underlying rhythm is unreliable. The device has to be checked to ensure appropriate programming and sensing pacing thresholds after surgery. The implantable cardioverter defibrillator should be turned off during surgery and switched on in the recovery phase before discharge to the ward.

    The prevalence and cost of subsequent fractures among patients with an incident fracture are not well defined. To assess the prevalence of, and costs associated with, subsequent fractures in the year after an incident fracture. This was a retrospective claims database analysis using data from Humana Medicare Advantage claims (Medicare group) and Optum Insight Clinformatics Data Mart commercial claims (commercial group). Patients included in the study had a claim for a qualifying fracture occurring between January 2008 and December 2013 (index fracture), were continuously enrolled in the health plan for ≥ 1 year before and after the index fracture, and were aged ≥ 65 years in the Medicare group or ≥ 50 years in the commercial group at the time of the index fracture. Subsequent fractures were identified by ICD-9-CM codes and were defined as the second fracture occurring ≥ 3 to ≤ 12 months after the index fracture (≥ 6 to ≤ 12 months for fractures at the same site as the index fracture). Rates of subsequent fractures were calculated as the number of patients who had a subsequent fracture divided by the total sample size. After propensity matching of demographic and clinical variables, we determined the total medical and pharmacy costs accrued within 1 year of the index fracture by patients with and without a subsequent fracture. Health care costs were compared between patients with and without a subsequent fracture using McNemar's test. A total of 45,603 patients were included in the Medicare group, and 54,145 patients were included in the commercial group. In the Medicare group, 7,604 (16.7%) patients experienced a subsequent fracture. The proportion of patients with a subsequent fracture was highest among patients with multiple index fractures (26.2%, n = 905), followed by those with hip (25.5%, n = 1,280) and vertebral (20.2%, n = 1,908) index fractures. In the commercial group, 6,256 (11.6%) patients experienced a subsequent fracture. The proportion

    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.

    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.

  13. Iron Overload in Patients Undergoing Hematopoietic Stem Cell Transplantation

    Recipients of hematopoietic stem cell transplantation (HSCT) frequently have iron overload resulting from chronic transfusion therapy for anemia. In some cases, for example, in patients with myelodysplastic syndromes and thalassemia, this can be further exacerbated by increased absorption of iron from the gut as a result of ineffective erythropoiesis. Accumulating evidence has established the negative impact of elevated pretransplantation serum ferritin, a surrogate marker of iron overload, on overall survival and nonrelapse mortality after HSCT. Complications of HSCT associated with iron overload include increased bacterial and fungal infections as well as sinusoidal obstruction syndrome and possibly other regimen-related toxicities. Based on current evidence, particular attention should be paid to prevention and management of iron overload in allogeneic HSCT candidates, especially in patients with thalassemia and myelodysplastic syndromes. The pathophysiology of iron overload in the HSCT patient and optimum strategies to deal with iron overload during and after HSCT require further study. PMID:20871852

    Hysterectomy and laparoscopy are the two most common surgical options used to treat women with endometriosis, yet the disease may still recur. This study aimed to determine the long-term retreatment rates among endometriosis patients in the United States who received either hysterectomy or laparoscopy. Patients aged 18-49 years with endometriosis who underwent hysterectomy or laparoscopy were identified in the Truven Health MarketScan claims database (2004-2013). The retreatment rate up to 8 years after the initial surgery was estimated using Kaplan-Meier survival analysis. The relative risk of retreatment among patients with hysterectomy versus laparoscopy was assessed using a Cox proportional hazard model. A total of 24,915 patients with endometriosis who underwent hysterectomy and 37,308 patients with endometriosis who underwent laparoscopy were identified. The estimated retreatment rates were 3.3%, 4.7%, and 5.4% in the 2nd, 5th, and 8th year following hysterectomy, respectively, while the rates following laparoscopy were 15.8%, 27.5%, and 35.2%, respectively. The hazard ratio of retreatment was 0.157 (95% confidence interval [CI]: 0.146-0.169) comparing hysterectomy to laparoscopy. In the sensitivity analysis, which expanded the definition of retreatment by including medical treatments, the retreatment rate increased by a factor of 11-14 for the hysterectomy cohort and by a factor of 2-4 for the laparoscopy cohort, and the hazard ratio of retreatment rate for hysterectomy versus laparoscopy was 0.490 (95% CI: 0.477-0.502). Our study results indicated that the disease retreatment rate after laparoscopy is high among patients with endometriosis; even hysterectomy does not guarantee freedom from retreatment.

    Bisphosphonate-related jaw necrosis (BRONJ) associated with dental implants is a rare but continuously reported complication. To verify clinical and pathological characteristics of BRONJ around dental implants, the present study analyzed clinical, radiographic and histopathological findings of these lesions. Nineteen patients were diagnosed with osteonecrosis of the jaw associated with dental implants and treated at our institute from 2008 to 2011. The patients' medical history, demographic features, radiographic, and histopathological findings along with information on bisphosphonates (BP) administration were analyzed. The majority of BRONJ patients associated with dental implants used oral BP for osteoporosis. The patients were divided into two groups: BP initiation before (n = 16) and after (n = 3) implant surgery. Only three patients (15.8%) could be regarded as "implant surgery-triggered" BRONJ. Many patients (n = 9) showed successful osteointegration after fixture installation to an average of 35 months (11-82 months) until the development of osteonecrosis. The histological features of the lesion showed that the necrotic bone with empty lacunae was infiltrated by inflammatory cells and bacterial colonies. Viable osteocytes were also observed in some areas of the bony specimens. Three types of bone destruction pattern were observed: (i) complete necrosis of the bone around the implant (frozen type), (ii) extensive osteolysis around the implant with or without sequestra (osteolytic type), and (iii) sequestration of bone with an implant maintaining direct implant-bone contact (en block sequestration type). These findings could be existed at the same lesions depending on the degree of local bone destruction and the severity of the infection. These results and those of others suggested that already osseointegrated dental implants can also cause the osteonecrosis around the implant after BP administration. En block sequestration of bone with implant might be one of

    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.

    Pulmonary artery pressure (PAP) is known to regress after successful balloon mitral valvotomy (BMV). Data of persistent pulmonary artery hypertension (PPAH) following BMV is scarce. We analyzed the clinical, echocardiographic, and hemodynamic data of 701 consecutive patients who have undergone successful BMV in our institute from 1997 to 2003. Data of 287 patients who had PPAH (defined by pulmonary artery systolic pressure [PASP] of ≥ 40 mmHg at one year following BMV) were compared to the data of 414 patients who did not have PPAH. Patients who had PPAH were older (39.9 ± 9.9 years vs. 29.4 ± 10.1; P < 0.001). They had higher prevalence of atrial fibrillation (AF; 21.9 vs. 12.1%, P < 0.05), moderate or severe pulmonary artery hypertension (PAH) defined as PASP more than 50 mmHg (43.5 vs. 33.8%, P = 0.00), anatomically advanced mitral valve disease as assessed by Wilkin's echocardiographic score > 8 (33.7 vs. 23.2%, P < 0.001), and coexistent aortic valve disease (45.6 vs. 37.9%, P < 0.001) at the baseline. Those patients with PPAH had comparatively lower immediate postprocedural mitral valve area (MVA). On follow-up of more than five years, the occurrence of restenosis (39.3 vs. 10.1%, P = 0.000), new onset heart failure (14% vs. 4%, P < 0.05) and need for reinterventions (9.5% vs. 2.8%, P < 0.05) were higher in the PPAH group. Patients with PPAH were older, sicker, and had advanced rheumatic mitral valve disease. They had higher incidence of restenosis, new onset heart failure, and need for reinterventions on long term follow-up. PPAH represents an advanced stage of rheumatic valve disease and indicates chronicity of the disease, which may be the reason for the poorer prognosis of these patients. Patients with PPAH requires intense and more frequent follow-up. PMID:24015345

    Increasing surgical access to previously underserved populations in the United States may require a major expansion of the use of operating rooms on weekends to take advantage of unused capacity. Although the so-called weekend effect for surgery has been described in other countries, it is unknown whether US patients undergoing moderate-to-high risk surgery on weekends are more likely to experience worse outcomes than patients undergoing surgery on weekdays. The aim of this study was to determine whether patients undergoing surgery on weekends are more likely to die or experience a major complication compared with patients undergoing surgery on a weekday. Using all-payer data, we conducted a retrospective cohort study of 305,853 patients undergoing isolated coronary artery bypass graft surgery, colorectal surgery, open repair of abdominal aortic aneurysm, endovascular repair of abdominal aortic aneurysm, and lower extremity revascularization. We compared in-hospital mortality and major complications for weekday versus weekend surgery using multivariable logistic regression analysis. After controlling for patient risk and surgery type, weekend elective surgery [adjusted odds ratio (AOR)=3.18; 95% confidence interval (CI), 2.26-4.49; P<0.001] and weekend urgent surgery (AOR=2.11; 95% CI, 1.68-2.66; P<0.001) were associated with a higher risk of death compared with weekday surgery. Weekend elective (AOR=1.58; 95% CI, 1.29-1.93; P<0.001) and weekend urgent surgery (AOR=1.61; 95% CI, 1.42-1.82; P<0.001) were also associated with a higher risk of major complications compared with weekday surgery. Patients undergoing nonemergent major cardiac and noncardiac surgery on the weekends have a clinically significantly increased risk of death and major complications compared with patients undergoing surgery on weekdays. These findings should prompt decision makers to seek to better understand factors, such physician and nurse staffing, which may contribute to the weekend effect.

    An algorithm for use of Prasugrel (Effient) in patients undergoing cardiac catheterization and percutaneous coronary intervention at the Brigham and Women's Hospital is presented. Our algorithm, which is in the process of being implemented, is consistent with published and generally accepted standards of care and is based on data from the pivotal Trial to Assess Improvement in Therapeutic Outcomes by Optimizing Platelet Inhibition with Prasugrel-Thrombolysis in Myocardial Infarction (TRITON-TIMI) 38, which compared clopidogrel with prasugrel in acute coronary syndrome patients undergoing percutaneous coronary intervention. Areas of focus include analysis of the benefit of prasugrel over clopidogrel in acute coronary syndrome patients and appropriate selection of patients for prasugrel treatment.

    Oral lesions (OL) have an important prognostic value for HIV/AIDS patients. However, the behavior of OL in HIV/AIDS patients undergoing highly active antiretroviral therapy including efavirenz (HAART/EFV) has not been documented. Our objective was to establish the prevalence of OL in HIV/AIDS patients undergoing HAART/EFV and to compare it with the prevalence of OL in patients undergoing antiretroviral therapy including a protease inhibitor (HAART/PI). Seventy-three HIV/AIDS patients undergoing antiretroviral treatment for at least for 6 months at "La Raza" Medical Center's Internal Medicine Unit (IMSS, Mexico City) were included. To detect OL, a detailed examination of oral soft tissues was performed in each patient. Patient records recorded gender, seropositivity time, route of contagion, antiretroviral therapy type and duration, CD4 lymphocyte count/ml, and viral load. Two groups were formed: 38 patients receiving HAART/EFV [two nucleoside analogue reverse transcriptase inhibitors (NARTI) plus efavirenz] and 35 patients receiving HAART/PI (two NARTIs plus one PI). OL prevalence was established in each study group. The Chi-square test was applied (p < 0.05(IC95%)). OL prevalence in the HAART/EFV group (32%) was lower (p < 0.007) than in the HAART/PI group (63%). Candidosis was the most prevalent OL in both groups. Herpes labialis, HIV-associated necrotizing periodontitis, xerostomia, hairy leukoplakia, and nonspecific oral sores were identified. The highest prevalence for all OL was found in the HAART/PI group. These findings suggest that HIV/AIDS patients undergoing HAART/EFV show a lower prevalence of oral lesions than patients undergoing HAART/PI.

    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.

    Chronic kidney disease (CKD)-associated pruritus is a significant clinical symptom affecting more than 50% of patients on hemodialysis. Restricted by the availability of effective therapeutic options, the management of CKD-associated pruritus remains a treatment challenge. Evaluating research in this area is difficult, as most studies are not comparable due to differing methodologies and study designs, limited number of patients, and the lack of standardized measures. The most frequently used therapy is UVB phototherapy, eliciting favorable responses in most patients. Newer approaches, such as treatment with the m-opiod-receptor antagonist, naltrexone, have yielded conflicting results. The use of the k-opioid-receptor-agonist, nalfurafine, appears to be partially effective in relieving CKD-associated pruritus, as shown by a meta-analysis of 2 clinical trials. Promising results have been obtained by treatment with the anticonvulsant gabapentin. CKD-associated pruritus is thought to be mediated by a proinflammatory state, which explains why immunomodulating drugs (e.g., thalidomide, tacrolimus, and pentoxiphylline) are effective in some patients. Treatment of CKD-associated pruritus should be undertaken according to individual benefit-risk ratio assessments.

    We had two patients with hypertrophic cardiomyopathy for noncardiac surgeries. Case 1: A 74-year-old man for right nephrectomy received epidural lidocaine and nitrous oxide combined with 0.2-0.6% isoflurane. During the operation, heart rate and blood pressure were relatively unstable, but he woke up promptly after the operation. Early on the morning of the 2nd post-operative day, he was found dead on his bed. Case 2: A 52-year-old man for gastrectomy was anesthetized with nitrous oxide and halothane with continuous propranolol infusion. Through the operative period, heart rate and blood pressure were stable and postoperative course was uneventful. In these two patients, preoperative Holter ECG showed ventricular tachycardia, which may increase the risk of a sudden death. These cases demonstrate that general anesthesia with nitrous oxide combined with halothane, can be administered with a low risk in patients with HCM for noncardiac surgery and that postoperative intensive care unit monitoring is necessary for these patients for several days to prevent a sudden death.

    The purpose of the study was to determine the prevalence in liver transplant (OLTx) patients of the hepatitis markers (anti-A, anti-B, anti-C, anti-D and HBsAg) and the interrelationships between markers and patients’ sexes, ages, dates of transplant, clinicopathological diagnoses, and short-term survivals. Slightly more than half of the patients were male. Anti-A and anti-B were about evenly distributed between male and female. Anti-C, anti-D, and HBsAg were far more common in males. Age and year of transplant showed only a moderate increase in anti-A with increasing age. Anti-A was found in 57% of all patients, anti-B in 18%, anti-C in 17%, and HBsAg in 17%. Anti-D was tested only in patients who were positive for anti-B or HBsAg and occurred in 21 (11%) of 185. The poorest short-term survival occurred in males who showed both anti-A and HBsAg.

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

    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

    The purpose of this retrospective study was to determine the prevalence of sarcopenia and sarcopenic obesity among patients who underwent orthopedic surgery (OS). 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/m(2). 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/cm(2)) 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%. Our study demonstrated a high prevalence of sarcopenia among OS patients.

    The purpose of this study is to compare pain experience and cooperation between consecutive surgeries in patients undergoing phacoemulsification in both eyes, using sub-Tenon's local anesthesia without sedation. In this study, 268 patients with bilateral senile cataracts were recruited. All operations were performed without sedation, using a clear corneal phacoemulsification technique and sub-Tenon's local anesthesia, by one of four surgeons. The first surgery was performed on the eye with the higher grade cataract. The other eye was operated on within 3 months by the same surgeon (mean interval 1.9 ± 1.1 months). All patients were asked to grade their pain experience during induction and maintenance of anesthesia and also during the phacoemulsification surgery, using a visual analogue scale (VAS) from 0 (no pain) to 10 (unbearable pain) administered after the surgery. The cooperation of the patient was graded from 0 (no event) to 3 (markedeye and head movement and lid squeezing) by the attending surgeon. The VAS scores and cooperation scores of the patients were the outcome measurements. The mean pain score was 2.11 ± 0.79 in the first eye and 3.33 ± 0.80 in the second eye during the administration of sub-Tenon's anesthesia, and 1.50 ± 0.60 in the first eye and 2.10 ± 0.57 in the second eye during the phacoemulsification surgery. The patient cooperation score was 1.60 ± 0.75 in the first surgery and 2.08 ± 0.72 in the second surgery. The differences between the first and second surgeries were statistically significant for all outcome measures (p < 0.01). Patients who previously underwent phaco surgery in one eye experienced more pain and showed worse cooperation during the phaco surgery in the second eye, especially if there was a short time between the surgeries, viz., less than 3 months. Therefore, if the surgeon has difficulty in the first operation gaining the patient's cooperation, the surgeon must be careful: if contralateral eye

    The coexistence of diabetes, hypertension, obesity, and dyslipidemia is defined as metabolic syndrome. Studies show substantial cardiovascular risks among these patients. The risk of patients with metabolic syndrome undergoing total joint arthroplasty (TJA) is unknown. Patients with and without metabolic syndrome undergoing TJA during a 3-year period were analyzed for postoperative complications. Metabolic syndrome was defined by having 3 of the following 4 criteria: obesity (body mass index ≥30 kg/m(2)), dyslipidemia, hypertension, and diabetes. Patients with metabolic syndrome had a significantly higher risk of cardiovascular complications compared with controls (P = .017). The risk of an adverse event increased by 29% and 32%, respectively, when there were 3 or 4 syndrome components. Patients with metabolic syndrome undergoing TJA have increased risk for cardiovascular complications. Our results show that metabolic syndrome may have a clustering effect and pose increased risk when individual risks factors are combined. Copyright © 2012 Elsevier Inc. All rights reserved.

    The main objective of the study is to assess the nutritional status in patients on chronic haemodialysis in Jamaica using the Subjective Global Assessment tool and to correlate this with measured serum nutritional biomarkers, and also to identify nutritional biomarkers that can be used to assess nutritional status of patients with end-stage renal disease (ESRD). Two hundred and nine consecutive patients on haemodialysis were selected from dialysis centres in Kingston, the capital of Jamaica, St. Catherine and Manchester Jamaica. The nutritional status of each participant was assessed using the Subjective Global Assessment tool in an interview performed by the researcher. Serum albumin, blood urea nitrogen and creatinine, highly sensitive complement reactive protein (hsCRP) and total fasting cholesterol were determined from a single serum sample. Only patients with ESRD were selected. Patients with acute renal failure or those with ESRD who were admitted in the previous two weeks were excluded from the study. Informed consent was obtained prior to interview and obtaining blood samples. Of the total participants, 54.5% (n=114) were male and 45.5% (n=95) female. The mean age for males was 51.9 years and females 47.6 years. Diabetes was documented as the most common cause of chronic renal disease and was found in 29.7%, hypertension in 24.4% and chronic glomerulonephritis in 22% of the participants. Approximately 80% of the study population had moderate malnutrition. There was a significant association between moderate malnutrition and a diagnosis of ESRD secondary to diabetes mellitus, p = 0.03. Being on haemodialysis for < or = six months was significantly associated with moderate malnutrition p = 0.002. Also associated with moderate malnutrition were presence of an arteriovenous (AV) fistula (p = 0.01), serum albumin of < 40 g/L (OR 3.68, p = 0.001), pre-dialysis creatinine of <880 micromol/L (p = 0.02) and cholesterol < 3.9 mmol/L (p = 0.04).

    Background: The Patient-Reported Outcomes Measurement Information System (PROMIS) consists of question banks for health domains through computer adaptive testing (CAT). Hypothesis: For patients with glenohumeral arthritis, (1) there would be high correlation between traditional patient-reported outcome (PRO) measures and the PROMIS upper extremity item bank (PROMIS UE) and PROMIS physical function CAT (PROMIS PF CAT), and (2) PROMIS PF CAT would not demonstrate ceiling effects. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: Sixty-one patients with glenohumeral osteoarthritis were included. Each patient completed the American Shoulder and Elbow Surgeons (ASES) assessment form, Marx Shoulder Activity Scale, Short Form–36 physical function scale (SF-36 PF), EuroQol 5 Dimensions (EQ-5D) questionnaire, Western Ontario Osteoarthritis Shoulder (WOOS) index, PROMIS PF CAT, and the PROMIS UE. Correlation was defined as high (>0.7), moderate (0.4-0.6), or weak (0.2-0.3). Significant floor and ceiling effects were present if more than 15% of individuals scored the lowest or highest possible total score on any PRO. Results: The PROMIS PF demonstrated excellent correlation with the SF-36 PF (r = 0.81, P < .0001) and good correlation with the ASES (r = 0.62, P < .0001), EQ-5D (r = 0.64, P < .001), and WOOS index (r = 0.51, P < .01). The PROMIS PF demonstrated low correlation with the Marx scale (r = 0.29, P = .02). The PROMIS UE demonstrated good correlation with the ASES (r = 0.55, P < .0001), SF-36 (r = 0.53, P < .01), EQ-5D (r = 0.48, P < .01), and WOOS (r = 0.34, P <.01), and poor correlation with the Marx scale (r = 0.06, P = .62). There were no ceiling or floor effects observed. The mean number of items administered by the PROMIS PRO was 4.

    The Patient-Reported Outcomes Measurement Information System (PROMIS) consists of question banks for health domains through computer adaptive testing (CAT). For patients with glenohumeral arthritis, (1) there would be high correlation between traditional patient-reported outcome (PRO) measures and the PROMIS upper extremity item bank (PROMIS UE) and PROMIS physical function CAT (PROMIS PF CAT), and (2) PROMIS PF CAT would not demonstrate ceiling effects. Cohort study (diagnosis); Level of evidence, 3. Sixty-one patients with glenohumeral osteoarthritis were included. Each patient completed the American Shoulder and Elbow Surgeons (ASES) assessment form, Marx Shoulder Activity Scale, Short Form-36 physical function scale (SF-36 PF), EuroQol 5 Dimensions (EQ-5D) questionnaire, Western Ontario Osteoarthritis Shoulder (WOOS) index, PROMIS PF CAT, and the PROMIS UE. Correlation was defined as high (>0.7), moderate (0.4-0.6), or weak (0.2-0.3). Significant floor and ceiling effects were present if more than 15% of individuals scored the lowest or highest possible total score on any PRO.

    Background: Oral mucositis (OM) is a painful consequence of myeloablative hematopoietic cell transplantation (HCT). Extraorally delivered photobiomodulation therapy (PBMT) is a promising novel intervention for the prevention of OM in children. Objectives: With funding from an NIDCR R34 planning grant, the objectives of this study are 1) to model the dosimetry of external PBMT and the optimal device parameters for the planned clinical trial, and 2) to plan and design a placebo-controlled Phase 2 multicenter clinical trial to determine whether extraorally delivered PBMT can reduce the duration of severe OM in children, with intent for implementation under subsequent U01 funding. Methods: External PBMT dosimetry will be evaluated using pediatric head and neck MRI studies to obtain serial measurements of different tissues that will then be used to develop a sophisticated computational model. We plan to conduct a placebocontrolled Phase 2 multicenter clinical trial in which patients 4 to 21 years of age will be randomized 1:1:1 to receive external PBMT dose 1x, external PBMT dose 2x, or sham PBMT starting from conditioning, daily until day +20 post- HCT. Significance: Extraorally delivered PBMT is a feasible, potentially efficacious intervention that could improve the quality of life for all children undergoing myeloablative HCT. The planned Phase 2 study, based on rigorous dose modeling and with detailed attention to uniform delivery of therapy and OM assessments, will provide critical efficacy data and the potential basis for a subsequent definitive Phase 3 trial.

    Patients with liver disease requiring surgical procedures are at increased perioperative risk. In addition, the deleterious effect of anesthesia on hepatocellular function, altered drug pharmacokinetics, aberrant hemostasis, postoperative encephalopathy and infection, with multiorgan failure, all contribute to perioperative morbidity and mortality. Although limited by the lack of widely accepted quantitative liver function tests, preoperative evaluation and risk assessment is imperative. Acute viral hepatitis, alcoholic hepatitis, refractory coagulopathy, Child's class C cirrhosis, and emergent surgery are major risk factors predictive of a poor outcome. In addition, elective abdominal surgical procedures should be avoided in potential candidates for orthotopic liver transplantation. Identification and correction of reversible risk factors via meticulous preoperative definition of the etiology, chronicity, and severity of the patient's liver disease within the confines of surgical urgency is the goal of the preoperative hepatology consultation.

    Hypersensitivity reactions to chemotherapeutic agents can cause the discontinuation of first-line therapies. Chemotherapy desensitization is a safe, but labor-intensive, process to administer these important medications. A desensitization protocol can enable a patient to receive the entire target dose of a medication, even if the patient has a history of severe infusion reactions. In this article, the authors explain the pathophysiology of hypersensitivity reactions and describe the recent development of desensitization protocols in oncology. In part II of this article, which will appear in the April 2016 issue of the Clinical Journal of Oncology Nursing, the authors will give a detailed account of how a desensitization protocol is performed at an academic medical center.

    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

    to estimate the prevalence of infection by respiratory viruses in pediatric patients with cancer and acute respiratory infection (ARI) and/or fever. cross-sectional study, from January 2011 to December 2012. The secretions of nasopharyngeal aspirates were analyzed in children younger than 21 years with acute respiratory infections. Patients were treated at the Grupo em Defesa da Criança Com Câncer (Grendacc) and University Hospital (HU), Jundiaí, SP. The rapid test was used for detection of influenza virus (Kit Biotrin, Inc. Ireland), and real-time multiplex polymerase chain reaction (FTD, Respiratory pathogens, multiplex Fast Trade Kit, Malta) for detection of influenza virus (H1N1, B), rhinovirus, parainfluenza virus, adenovirus, respiratory syncytial virus, human parechovirus, bocavirus, metapneumovirus, and human coronavirus. The prevalence of viral infection was estimated and association tests were used (χ(2) or Fisher's exact test). 104 samples of nasopharyngeal aspirate and blood were analyzed. The median age was 12 ± 5.2 years, 51% males, 68% whites, 32% had repeated ARIs, 32% prior antibiotic use, 19.8% cough, and 8% contact with ARIs. A total of 94.3% were in good general status. Acute lymphocytic leukemia (42.3%) was the most prevalent neoplasia. Respiratory viruses were detected in 50 samples: rhinoviruses (23.1%), respiratory syncytial virus AB (8.7%), and coronavirus (6.8%). Co-detection occurred in 19% of cases with 2 viruses and in 3% of those with 3 viruses, and was more frequent between rhinovirus and coronavirus 43. Fever in neutropenic patients was observed in 13%, of which four (30.7) were positive for viruses. There were no deaths. the prevalence of respiratory viruses was relevant in the infectious episode, with no increase in morbidity and mortality. Viral co-detection was frequent in patients with cancer and ARIs. Copyright © 2014 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda. All rights reserved.

    AIM: To evaluate the impact of body mass index (BMI) on short and long term results after pancreaticoduodenectomies (PD). METHODS: A consecutive series of PDs performed at the Karolinska University Hospital from 2004 till 2010 were retrieved from our prospective database. The patients were divided by BMI into overweight/obese (O; BMI ≥ 25 kg/m2) and controls (C; BMI < 25 kg/m2). Demographics, peri-operative data, morbidity, mortality, pancreatic fistula (PF) rate, length of stay (LOS), hospital costs, histology, and survival were analyzed. An additional sub analysis of survival was performed in patients with a diagnosis of pancreatic ductal adenocarcinoma (PDAC) and divided in underweight, normal-weight, overweight and obese. RESULTS: A total of 367 PDs were included (O = 141/C = 226). No differences were found between O and C regarding demographics, peri-operative data, costs, morbidity or mortality. O was associated with higher intra-operative blood loss (1392 ± 115 mL vs 1121 ± 83 mL; P = 0.01), rate of PF (20% vs 9.5%; P = 0.006) and marginally longer LOS (18 ± 0.9 d vs 15 ± 1.1 d; P = 0.05). An increasing risk for PF was observed with increasing BMI. The 1, 3 and 5 years survival rate was similar in O and C in PDAC (68.7%, 26.4% and 8.8% vs 66.1%, 30.9% and 17.9% respectively; P = 0.9). When the survival was analyzed using 4 different categories of BMI (underweight, normal, overweight and obese), a trend was seen toward a difference in survival, with a worse prognosis for the underweight and obese patients compared to normal weight and overweight patients. CONCLUSION: Overweight increases the risk for intra-operative bleeding and PF, but do not otherwise alter short or long term outcome after PD for pancreatic cancer. PMID:23755369

  20. Respiratory infections in patients with cystic fibrosis undergoing lung transplantation.

    Cystic fibrosis is an inherited disease characterised by chronic respiratory infections associated with bronchiectasis. Lung transplantation has helped to extend the lives of patients with cystic fibrosis who have advanced lung disease. However, persistent, recurrent, and newly acquired infections can be problematic. Classic cystic fibrosis-associated organisms, such as Staphylococcus aureus and Pseudomonas aeruginosa, are generally manageable post-transplantation, and are associated with favourable outcomes. Burkholderia cenocepacia poses particular challenges, although other Burkholderia species are less problematic. Despite concerns about non-tuberculous mycobacteria, especially Mycobacterium abscessus, post-transplantation survival has not been definitively shown to be less than average in patients with these infections. Fungal species can be prevalent before and after transplantation and are associated with high morbidity, so should be treated aggressively. Appropriate viral screening and antiviral prophylaxis are necessary to prevent infection with and reactivation of Epstein-Barr virus and cytomegalovirus and their associated complications. Awareness of drug pharmacokinetics and interactions in cystic fibrosis is crucial to prevent toxic effects and subtherapeutic or supratherapeutic drug dosing. With the large range of potential infectious organisms in patients with cystic fibrosis, infection control in hospital and outpatient settings is important. Despite its complexity, lung transplantation in the cystic fibrosis population is safe, with good outcomes if the clinician is aware of all the potential pathogens and remains vigilant by means of surveillance and proactive treatment.

    Kidney transplant is a last resort to increase the life expectancy and quality of life in patients with renal failure. Aortic dissection is a disease that requires emergency intervention; it is characterized by sudden life-threatening back or abdominal pain. In the case described, constant chest pain that increased with respiration was present on examination of a 28-year-old man (85 kg, 173 cm) who presented at our emergency department complaining of severe back pain. He had undergone a kidney transplant in 2004 from his mother (live donor). He was diagnosed with acute Type II aortic dissection and was scheduled for emergent surgery. Because there were no surgical or anesthetic complications, the patient with 79 and 89 minutes aortic cross-clamping and cardiopulmonary bypass durations was sent, intubated, to intensive care unit. When nephrotoxic agents are avoided and blood flow is stabilized, cardiovascular surgery with cardio-pulmonary bypass may be performed seamlessly in patients who have undergone a kidney transplant.

    To determine feasibility and safety of proactive enteral tube feeding (ETF) in pediatric oncology patients. Pediatric patients with newly diagnosed brain tumors, myeloid leukemia or high-risk solid tumors were eligible. Subjects agreeing to start ETF before cycle 2 chemotherapy were considered proactive participants (PPs). Those who declined could enroll as chart collection receiving nutritional standard of care. Nutritional status was assessed using standard anthropometric measurements. Episodes of infection and toxicity related to ETF were documented from diagnosis to end of therapy. A descriptive comparison between PPs and controls was conducted. One hundred four eligible patients were identified; 69 enrolled (20 PPs and 49 controls). At diagnosis, 17% of all subjects were underweight and 26% overweight. Barriers to enrollment included physician, subject and/or family refusal, and inability to initiate ETF prior to cycle 2 of chemotherapy. Toxicity of ETF was minimal, but higher percentage of subjects in the proactive group had episodes of infection than controls. Thirty-nine percent of controls eventually started ETF and were twice as likely to receive parenteral nutrition. PPs experienced less weight loss at ETF initiation than controls receiving ETF and were the only group to demonstrate improved nutritional status at end of study. Proactive ETF is feasible in children with cancer and results in improved nutritional status at end of therapy. Episodes of infection in this study are concerning; therefore, a larger randomized trial is required to further delineate infectious risks and toxicities that may be mitigated by improved nutritional status. © 2013 Wiley Periodicals, Inc.

    Transcatheter aortic valve implantation (TAVI) is an established treatment option for symptomatic patients with severe aortic valvular disease who are not suitable for conventional surgical aortic valve replacement. Despite improving experience and techniques, ischaemic and bleeding complications after TAVI remain prevalent and impair survival in this generally old and comorbid-rich population. Due to changing aetiology of complications over time, antiplatelet and anticoagulant therapy after TAVI should be carefully balanced. Empirically, a dual antiplatelet strategy is generally used after TAVI for patients without an indication for oral anticoagulation (OAC; e. g. atrial fibrillation, mechanical mitral valve prosthesis), including aspirin and a thienopyridine. For patients on OAC, a combination of OAC and aspirin or thienopyridine is generally used. This review shows that current registries are unfit to directly compare antithrombotic regimens. Small exploring studies suggest that additional clopidogrel after TAVI only affects bleeding and not ischemic complications. However, these studies are lack in quality in terms of Cochrane criteria. Currently, three randomised controlled trials are recruiting to gather more knowledge about the effects of clopidogrel after TAVI.

    Bariatric surgical procedures are now a common method of obesity treatment with established effectiveness. Venous thromboembolism (VTE) events, which include deep vein thrombosis and pulmonary embolism, are an important source of postoperative morbidity and mortality among bariatric surgery patients. Due to an understanding of the frequency and seriousness of these complications, bariatric surgery patients typically receive some method of VTE prophylaxis with lower extremity compression, pharmacologic prophylaxis, or both. However, the optimal approach in these patients is unclear, with multiple open questions. In particular, strategies of adjusted-dose heparins, postdischarge anticoagulant prophylaxis, and the role of vena cava filters have been evaluated, but only to a limited extent. In contrast to other types of operations, the literature regarding VTE prophylaxis in bariatric surgery is notable for a dearth of prospective, randomized clinical trials, and current professional guidelines reflect the uncertainties in this literature. Herein, we summarize the available evidence after systematic review of the literature regarding approaches to VTE prevention in bariatric surgery. Identification of risk factors for VTE in the bariatric surgery population, analysis of the effectiveness of methods used for prophylaxis, and an overview of published guidelines are presented.

    Patients in a coma after cardiac arrest may have adversely affected drug absorption and metabolism. This study, the first of its kind, aimed to investigate the early pharmacokinetic and pharmacodynamic effects of ticagrelor administered through a nasogastric tube (NGT) to patients resuscitated after an out of hospital cardiac arrest (OHCA) and undergoing primary percutaneous coronary intervention (pPCI). Blood samples were drawn at baseline and at two, four, six, eight, 12, and 24 hours and then daily for up to five days after administration of a 180 mg ticagrelor loading dose (LD), followed by 90 mg twice daily in 44 patients. The primary endpoint was the occurrence of high platelet reactivity (HPR) 12 hours after the LD. Assessment by VerifyNow (VFN) showed 96 (15.25-140.5) platelet reactivity units (PRU), and five (12%) patients exhibited HPR. Multiplate analysis showed 19 (12-29) units (U) at twelve hours, and three patients (7%) had HPR. Ticagrelor and its main metabolite AR-C124910XX concentrations were 85.2 (37.2-178.5) and 18.3 (6.4-52.4) ng/mL. Median times to sufficient platelet inhibition below the HPR limit were 3 (2-6) hours (VFN) and 4 (2-8) hours (Multiplate). Ticagrelor, administered as crushed tablets through a nasogastric tube, leads to sufficient platelet inhibition after 12 hours, and in many cases earlier, in the vast majority of patients undergoing pPCI and subsequent intensive care management after an OHCA.

    Background Fibroblast growth factor 23 (FGF-23) is a hormone that increases the rate of urinary excretion of phosphate and inhibits renal production of 1,25-dihydroxyvitamin D, thus helping to mitigate hyperphosphatemia in patients with kidney disease. Hyperphosphatemia and low 1,25-dihydroxyvitamin D levels are associated with mortality among patients with chronic kidney disease, but the effect of the level of FGF-23 on mortality is unknown. Methods We examined mortality according to serum phosphate levels in a prospective cohort of 10,044 patients who were beginning hemodialysis treatment and then analyzed FGF-23 levels and mortality in a nested case–control sample of 200 subjects who died and 200 who survived during the first year of hemodialysis treatment. We hypothesized that increased FGF-23 levels at the initiation of hemodialysis would be associated with increased mortality. Results Serum phosphate levels in the highest quartile (>5.5 mg per deciliter [1.8 mmol per liter]) were associated with a 20% increase in the multivariable adjusted risk of death, as compared with normal levels (3.5 to 4.5 mg per deciliter [1.1 to 1.4 mmol per liter]) (hazard ratio, 1.2; 95% confidence interval [CI], 1.1 to 1.4). Median C-terminal FGF-23 (cFGF-23) levels were significantly higher in case subjects than in controls (2260 vs. 1406 reference units per milliliter, P<0.001). Multivariable adjusted analyses showed that increasing FGF-23 levels were associated with a monotonically increasing risk of death when examined either on a continuous scale (odds ratio per unit increase in log-transformed cFGF-23 values, 1.8; 95% CI, 1.4 to 2.4) or in quartiles, with quartile 1 as the reference category (odds ratio for quartile 2, 1.6 [95% CI, 0.8 to 3.3]; for quartile 3, 4.5 [95% CI, 2.2 to 9.4]; and for quartile 4, 5.7 [95% CI, 2.6 to 12.6]). Conclusions Increased FGF-23 levels appear to be independently associated with mortality among patients who are beginning hemodialysis

    Our aim was to determine the relationships between angiographic collaterals and diffusion/perfusion findings, subsequent infarct growth, and clinical outcome in patients undergoing endovascular therapy for ischemic stroke. Sixty patients with a thrombolysis in cerebral infarction (TICI) score of 0 or 1 and internal carotid artery/M1 occlusion at baseline were evaluated. A blinded reader assigned a collateral score using a previous 5-point scale, from 0 (no collateral flow) to 4 (complete/rapid collaterals to the entire ischemic territory). The analysis was dichotomized to poor flow (0-2) versus good flow (3-4). Collateral score was correlated with baseline National Institutes of Health Stroke Scale, diffusion-weighted imaging volume, perfusion-weighted imaging volume (Tmax ≥6 seconds), TICI reperfusion, infarct growth, and modified Rankin Scale score at day 90. Collateral score correlated with baseline National Institutes of Health Stroke Scale (P=0.002) and median volume of tissue at Tmax ≥6 seconds (P=0.009). Twenty-nine percent of patients with poor collateral flow had TICI 2B-3 reperfusion versus 65.5% with good flow (P=0.009). Patients with poor collaterals who reperfused (TICI 2B-3) were more likely to have a good functional outcome (modified Rankin Scale score 0-2 at 90 days) compared with patients who did not reperfuse (odds ratio, 12; 95% confidence interval, 1.6-98). There was no difference in the rate of good functional outcome after reperfusion in patients with poor collaterals versus good collaterals (P=1.0). Patients with poor reperfusion (TICI 0-2a) showed a trend toward greater infarct growth if they had poor collaterals versus good collaterals (P=0.06). Collaterals correlate with baseline National Institutes of Health Stroke Scale, perfusion-weighted imaging volume, and good reperfusion. However, target mismatch patients who reperfuse seem to have favorable outcomes at a similar rate, irrespective of the collateral score. http

    Background Readmission rates of 9.7%–15.5% after hepatectomy have been reported. These rates are difficult to interpret due to variability in the time interval used to monitor readmission. The aim of this study was to refine the definition of readmission after hepatectomy. Study Design A prospectively maintained database of 3041 patients who underwent hepatectomy from 1998 through 2013 was merged with the hospital registry to identify readmissions. Area under the curve (AUC) analysis was used to determine the time interval that best captured unplanned readmission. Results Readmission rates at 30 days, 90 days, and 1 year after discharge were 10.7% (n = 326), 17.3% (n = 526), and 31.9% (n = 971) respectively. The time interval that best accounted for unplanned readmissions was 45 days after discharge (AUC, 0.956; p < 0.001), during which 389 patients (12.8%) were readmitted (unplanned: n = 312 [10.3%]; planned: n = 77 [2.5%]). In comparison, the 30 days after surgery interval (used in the ACS-NSQIP database) omitted 65 (26.3%) unplanned readmissions. Multivariate analysis revealed the following risk factors for unplanned readmission: diabetes (odds ratio [OR], 1.6; p = 0.024), right hepatectomy (OR, 2.1; p = 0.034), bile duct resection (OR, 1.9; p = 0.034), abdominal complication (OR, 1.8; p = 0.010), and a major postoperative complication (OR, 2.4; p < 0.001). Neither index hospitalization > 7 days nor postoperative hepatobiliary complications were independently associated with readmission. Conclusions To accurately assess readmission after hepatectomy, patients should be monitored 45 days after discharge. PMID:26047760

    Readmission rates of 9.7% to 15.5% after hepatectomy have been reported. These rates are difficult to interpret due to variability in the time interval used to monitor readmission. The aim of this study was to refine the definition of readmission after hepatectomy. A prospectively maintained database of 3,041 patients who underwent hepatectomy from 1998 through 2013 was merged with the hospital registry to identify readmissions. Area under the curve (AUC) analysis was used to determine the time interval that best captured unplanned readmission. Readmission rates at 30 days, 90 days, and 1 year after discharge were 10.7% (n = 326), 17.3% (n = 526), and 31.9% (n = 971) respectively. The time interval that best accounted for unplanned readmissions was 45 days after discharge (AUC, 0.956; p < 0.001), during which 389 patients (12.8%) were readmitted (unplanned: n = 312 [10.3%]; planned: n = 77 [2.5%]). In comparison, the 30 days after surgery interval (used in the ACS-NSQIP database) omitted 65 (26.3%) unplanned readmissions. Multivariate analysis revealed the following risk factors for unplanned readmission: diabetes (odds ratio [OR] 1.6; p = 0.024), right hepatectomy (OR 2.1; p = 0.034), bile duct resection (OR 1.9; p = 0.034), abdominal complication (OR 1.8; p = 0.010), and a major postoperative complication (OR 2.4; p < 0.001). Neither index hospitalization > 7 days nor postoperative hepatobiliary complications were independently associated with readmission. To accurately assess readmission after hepatectomy, patients should be monitored 45 days after discharge. Copyright © 2015 American College of Surgeons. Published by Elsevier Inc.

    We retrospectively examined prophylactic antibiotic use and documentation of wound classification in patients having gynecologic surgery at a tertiary hospital. Of the 326 cases reviewed, 175 (54%) received prophylactic antibiotics when not indicated according to guidelines of the American College of Obstetricians and Gynecologists. Antibiotic administration varied significantly (P < 0.02) among the different types of surgery, being given in 82% of laparoscopic cases, 35% of nonobstetrical dilation and curettage and operative hysteroscopy procedures, and 51% of open abdominal procedures. There were no recorded episodes of anaphylaxis or pseudomembranous colitis. In conclusion, antibiotic use is high among gynecologic surgeons at a tertiary hospital, but this use was unnecessary.

    Perioperative hemodynamic instability still remains the biggest surgical and anesthetic challenge in surgery for pheochromocytoma. The aim of this review was to discuss pre-, intra- and postoperative factors that may impact on hemodynamic condition of a patient. It describes patients’ preparation with appropriate medication, principles of surgical technique as well as risk factors for development of hemodynamic instability in postoperative period. Currently the gold standard in the treatment of pheochromocytoma is preoperative use of alpha-blockers and laparoscopic surgery. This approach allowed improving outcomes by lowering both mortality and morbidity. PMID:27867865

    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). 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. 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. 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.

    Vascular interventional radiology (VIR) procedures have increased markedly, partly due to the current healthcare context, which encourages the use of less invasive procedures that reduce pressure on surgery departments and decrease hospital stays. In most patients, these techniques can be carried out in a single intervention. VIR procedures are based on the possibility of gaining access to vascular structures through a catheter inserted percutaneously without the need for open surgery. Due to the complexity of these procedures, hospitalization is required before and after the technique is performed but length of stay is short compared with that associated with surgery. As the health workers closest to patients, nurses must respond to their information needs. The provision of comprehensive nursing care should include all the care required before, during and after the procedure and all aspects related to the quality of the healthcare process. Knowledge of how diagnostic and therapeutic VIR techniques are performed in the neurovascular section is essential. Based on the authors' experience, the present article aims to provide nurses with knowledge of some neurointerventional procedures (cerebral angiography and embolization of intracranial aneurysms) and of the care provided in RVI rooms.

    Psoriasis is a common chronic inflammatory skin disease but psoriasis patients with renal impairment undergoing dialysis are not frequently seen. Furthermore, the published work contains little information on the treatment with biologic drugs of patients with end-stage renal disease. We describe a 57-year-old man with refractory plaque-type psoriasis and end-stage renal disease due to polycystic kidney disease undergoing hemodialysis. He had tried topical medications and ultraviolet therapy for many years and was then treated with ustekinumab (an interleukin-12 and interleukin-23 blocker), which resulted in good clinical response along with stable renal function. After a few years of therapy, no side-effects have been observed. Our experience with this patient expands the spectrum of ustekinumab to include psoriasis patients with renal failure undergoing hemodialysis.

    This pilot study was performed to investigate the feasibility of pre-surgical pulmonary rehabilitation (PR) in morbidly obese patients with uncontrolled asthma, undergoing bariatric surgery. Four morbidly obese female patients with asthma participated in a 12-week PR program (exercise, diet, and psychological intervention) before undergoing bariatric surgery, and the outcomes were compared to a matched group of seven female controls (bariatric surgery only). In patients who participated in PR, asthma control and asthma quality of life improved dramatically after 3 months of PR. Besides, asthma control was better at the moment of surgery. The results of this pilot study show that PR is feasible in morbidly obese asthmatics and should be considered for a selected group of patients with uncontrolled asthma before undergoing bariatric surgery.

    Acentric chromosome fragments produced in cells by irradiation or other agents give rise to micronuclei in daughter cells. The micronuclei can be counted readily in large numbers of cells which provides a sensitive measure of chromosome aberrations. Previous studies have shown that the presence of contrast material enhances the radiation-induced yield of micronuclei in vitro. Micronuclei were scored in peripheral blood lymphocytes obtained from 26 patients before and after excretory urography (ExU). The results show a consistent and significant increase in the counts after ExU amounting to about one third of the counts blood samples before the examination. We conclude that the contrast medium contributed significantly to the increase in micronuclei.

    The purpose of this article is to provide an overview of the critical domains assessed during the psychological evaluation of candidates for bariatric surgery. Although no formal standard exists in the literature, there is growing recognition of the important elements to be addressed and the appropriate means for collecting the necessary data to determine psychological readiness for these procedures. Information regarding the components of the clinical interview and the specific measures used for psychological testing are discussed. Given the limited data on predicting success after surgery, determining psychological contraindications for surgery is addressed. Additionally, the multiple functions served by the psychologist during this assessment procedure are highlighted along with the value of this procedure in the patients' preparation for surgery.

    Carnitine is an essential cofactor for fatty acid (FA) metabolism, the predominant source of ATP in the normal aerobic heart. During myocardial ischemia, FA metabolism is impaired and tissue carnitine levels are depleted. Since the heart cannot synthesize carnitine, plasma carnitine could play an important role in maintaining myocardial carnitine levels during reperfusion. The purpose of this study was to determine the incidence of abnormal plasma carnitine concentrations in open heart surgery. Blood samples were obtained from eleven patients before, immediately after, and two hours after cardiopulmonary bypass (CPB). Total and free carnitine levels were significantly reduced immediately after CPB (p<0.01) and remained depressed until two hours after CPB (p<0.01 vs. pre CPB), while acyl carnitine levels were unchanged over the course of this study. These depressed free carnitine levels might affect cardiac metabolism in the heart after open heart surgery. Carnitine supplement might be a useful adjunct in the therapy after open heart surgery.

  20. Oral Complications and Management Strategies for Patients Undergoing Cancer Therapy

    PubMed Central

    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

    The pharmacokinetics of ceftizoxime were studied in 12 patients on continuous ambulatory peritoneal dialysis. After a 3-g intravenous dose, the steady-state volume of distribution was 0.23 +/- 0.05 liter kg-1, with an elimination half-life of 9.7 +/- 5.1 h. The peritoneal clearance of ceftizoxime (2.8 +/- 0.7 ml min-1) contributed modestly to the overall serum clearance of the drug (17.1 +/- 7.4 ml min-1) and was greater than the renal clearance (0.8 +/- 0.8 ml min-1). The peritoneal concentration rose to 91 +/- 29 micrograms ml-1 at 6 h, which was 0.61 +/- 0.17 of the serum concentration. A 3-g intravenous dose of ceftizoxime given every 48 h would result in adequate activity against most susceptible organisms, but more frequent dosing may be necessary for less susceptible organisms.

    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].

    Local anaesthetic-related systemic toxicity mainly results from elevated plasma concentrations of these drugs. We hypothesized that intraoral injection of submaximal doses of mepivacaine does not lead to toxic levels of this drug in blood. This study evaluated the plasma levels of mepivacaine in third molars surgeries. Twenty-one patients were randomly assigned into two groups: group I (two unilateral third molars; submaximal dose of mepivacaine 108 mg with epinephrine 54 μg) and group II (four third molars; submaximal dose of mepivacaine 216 mg with epinephrine 108 μg). Blood samples were collected before anaesthesia, and 5, 10, 15, 20, 30, 40, 60, 90 and 120 min after anaesthesia. Individual peak plasma concentrations ranged 0.77-8.31 μg/mL (group I) and from 2.36-7.72 μg/mL (group II). An increase in the average dose of mepivacaine from 1.88 ± 0.12 mg/kg (group I) to 3.35 ± 0.17 mg/kg (group II) increased the mean mepivacaine peak plasma levels from 2.33 ± 0.58 to 4.01 ± 0.69 μg/mL, respectively. Four patients obtained plasma levels of mepivacaine above the threshold for toxicity (5 μg/mL). Toxic levels of mepivacaine are possible, even when a submaximal dose is used. A twofold increase in the dose of mepivacaine caused the mean peak plasma concentration to increase proportionally, indicating that they may be predicted based on the relation of dose per bodyweight. © 2016 Australian Dental Association.

    Advancements in technology and medical treatment have made cancer care treatment more complex. With the current trend of sub-specialization in health care, cancer patients commonly receive care from multiple specialists and have wider treatment options. In view of this, there is a need to coordinate care and integrate information to enhance care and quality of outcomes for patients. Since the successful implementation of programs for increasing the survival rate of breast cancer patients at Harlem Hospital Center, New York, USA, patient navigation programs have been widely introduced in healthcare settings. Some literature has identified nurses as a primary candidate in assuming the role of a navigator. However, there is a need to further explore the effectiveness of patient navigation programs for their effectiveness in improving quality of life, and patient satisfaction and outcomes during the commencement of cancer treatment. The objective of this review was to synthesize the best available evidence on the effectiveness of patient navigation programs in adult cancer patients undergoing treatments such as radiotherapy and/or chemotherapy. This review considered studies that included adults aged 18 years and over, diagnosed with any type of cancer and undergoing treatment in an acute care hospital setting, including inpatient and outpatient/ambulatory care.This review considered studies that evaluated nurse-led patient navigation programs versus no patient navigation program or non-structured care coordination.A patient navigation program includes patient education, psychosocial support, and care coordination.This review considered randomized controlled trials and quasi-experimental studies.The review focused on the effects of patient navigator program clinical/patient outcomes. The review included studies on patient wellbeing and clinical outcomes, but excluded studies that had examined the impact of these programs on efficiency-related outcomes, such as length

To evaluate gastric histopathological changes in obese, and to compare with patients who underwent gastrojejunal bypass and the jejunal mucosa after the surgery. This is an observational study performed at a tertiary public hospital, evaluating endoscopic biopsies from 36 preoperative patients and 35 postoperative. 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%. 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. A obesidade mórbida é doença multifatorial cujo tratamento cirúrgico é cada vez mais indicado.

    Probiotics are live microorganisms, which as drugs or food supplements help to maintain health beneficial microbial balance in the digestive tract of a human or other host. Probiotics by their properties may help strengthen homeostasis and thus reduce side effects associated with cancer treatment. Experimental evidence suggests that probiotics might have beneficial effect on the toxicity of anticancer therapy. A computer-based literature search was carried out using PubMed (keywords: "probiotic" and "lactic acid bacteria" in association with the search terms "cancer" or "oncology" or "chemotherapy" or "radiation"); data reported at international meetings were included. Probiotics might have beneficial effects on some aspects of toxicity related to anticancer treatment especially radiation therapy. However, reported trials vary in utilized probiotic strains, dose of probiotics and vast majority of them are small trials with substantial risk of bias. Despite limited data, it seems that probiotic bacteria as live microorganisms could be safely administered even in the setting of neutropenia. Current evidence supporting probiotic use as adjunctive therapy to anticancer treatment is limited, especially in cancer patients treated with chemotherapy. Well designed clinical trials are needed to find true role of probiotics in oncology. Copyright © 2013 Elsevier Ltd. All rights reserved.

    1997-10-01

    Complications that arise after thyroid surgery may be associated with infection, hemorrhage, hormonal problems, and laryngeal nerve injury. Voice alteration after thyroidectomy is usually caused by recurrent or superior laryngeal nerve injury. This voice dysfunction may also be associated with laryngotracheal fixation with impairment of vertical movement or by temporary malfunction of the strap muscles after surgery. In this study, we evaluated the voice function phonetically before and after thyroidectomy in 54 patients, although function of the recurrent and superior laryngeal nerves was normal. During surgery, the superior and recurrent laryngeal nerves were identified and protected, and after surgery electromyographic testing of the cricothyroid muscle was performed. Typical voice symptoms after surgery were easy fatigue during phonation and difficulty with high pitch and singing voice. Acoustic analysis revealed that the phonation time and fundamental frequency were not changed after surgery, but the speaking fundamental frequency, range of speaking fundamental frequency, and vocal range were significantly diminished after surgery. These data allowed us to suggest that the cause of voice dysfunction is not seen in neural lesions, but in a disturbance of the extralaryngeal skeleton. These voice changes emphasize the importance of the extralaryngeal mechanism for pitch control.

    Many patients undergo elective coronary angiography without preprocedural stress testing that may be suitable if performed in patients with more angina pectoris or more frequently identified obstructive coronary artery disease (CAD). Patients in the National Cardiovascular Data Registry CathPCI Registry undergoing elective coronary angiography from July 2009 to April 2013 were assessed for differences in angina (Canadian Cardiovascular Society [CCS] class) and severity of obstructive CAD in those with and without preprocedural stress testing, stratified by CAD history. Given the large sample size, differences were considered clinically meaningful if the standardized difference (SD) was >10%. Of 790,601 patients without CAD history, 36.9% did not undergo preprocedural stress testing. Compared with patients with preprocedural stress testing, patients without preprocedural stress testing were more frequently angina free (CCS class 0; 28.2% with stress test vs 38.5% without, SD = 14.8%) and had similar rates of obstructive CAD (40.1% with stress test vs 35.7% without, SD = 9.0). Of 449,579 patients with CAD history, 44.2% did not undergo preprocedural stress testing. Patients without preprocedural stress testing reported more angina (CCS class III/IV angina: 17.8% vs 13.4%; SD = 11.3%) but were not more likely to have obstructive CAD (78.7% vs 81.1%; SD = 5.8%) than patients with preprocedural stress testing. In conclusion, approximately 40% of patients undergoing elective coronary angiography did not have preprocedural risk stratification with stress testing. For these patients, the clinical decision to proceed directly to invasive evaluation was not driven primarily by severe angina and did not result in higher detection rates for obstructive CAD.

    Highlights: Black-Right-Pointing-Pointer A-T cells were not hypersensitive to low levels of DNA DSBs. Black-Right-Pointing-Pointer A-T cells have enhanced Akt but defect in activation of p53 and apoptotic proteins. Black-Right-Pointing-Pointer A-T cells underwent premature senescence after DNA damage accumulated. Black-Right-Pointing-Pointer Chemotherapeutic effect in cancer therapy may be associated with premature senescence. -- Abstract: DNA DSBs are induced by IR or radiomimetic drugs such as doxorubicin. It has been indicated that cells from ataxia-telangiectasia patients are highly sensitive to radiation due to defects in DNA repair, but whether they have impairment in apoptosis has not been fully elucidated. A-T cells showed increased sensitivity to high levels of DNA damage, however, they were more resistant to low doses. Normal cells treated with combination of KU55933, a specific ATM kinase inhibitor, and doxorubicin showed increased resistance as they do in a similar manner to A-T cells. A-T cells have higher viability but more DNA breaks, in addition, the activations of p53 and apoptotic proteins (Bax and caspase-3) were deficient, but Akt expression was enhanced. A-T cells subsequently underwent premature senescence after treatment with a low dose of doxorubicin, which was confirmed by G2 accumulation, senescent morphology, and SA-{beta}-gal positive until 15 days repair incubation. Finally, A-T cells are radio-resistant at low doses due to its defectiveness in detecting DNA damage and apoptosis, but the accumulation of DNA damage leads cells to premature senescence.

    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.

    Background The drop in plasma albumin concentration following surgical trauma is well known, but the temporal pattern of the detailed mechanisms behind are less well described. The aim of this explorative study was to assess changes in albumin synthesis and transcapillary escape rate (TER) following major surgical trauma, at the time of peak elevations in two well-recognized markers of inflammation. Methods This was a clinical trial of radiolabeled human serum albumin for the study of TER and plasma volume. Ten patients were studied immediately preoperatively and on the 2nd postoperative day after major pancreatic surgery. Albumin synthesis rate was measured by the flooding dose technique employing incorporation of isotopically labelled phenylalanine. Results Fractional synthesis rate of albumin increased from 11.7 (95% CI: 8.9, 14.5) to 15.0 (11.7, 18.4) %/day (p = 0.027), whereas the corresponding absolute synthesis rate was unchanged, 175 (138, 212) versus 150 (107, 192) mg/kg/day (p = 0.21). TER was unchanged, 4.9 (3.1, 6.8) %/hour versus 5.5 (3.9, 7.2) (p = 0.63). Plasma volume was unchanged but plasma albumin decreased from 33.5 (30.9, 36.2) to 22.1 (19.8, 24.3) g/L. (p<0.001). Conclusion Two days after major abdominal surgery, at the time-point when two biomarkers of generalised inflammation were at their peak and the plasma albumin concentration had decreased by 33%, we were unable to show any difference in the absolute synthesis rate of albumin, TER and plasma volume as compared with values obtained immediately pre-operatively. This suggests that capillary leakage, if elevated postoperatively, had ceased at that time-point. The temporal relations between albumin kinetics, capillary leakage and generalised inflammation need to be further explored.

    Bronchofiberoscopy (BF) is a key tool used in the management of patients with respiratory diseases. Describing factors that contribute to patient anxiety surrounding BF has the potential to influence patient management and willingness to undergo the procedure again in the future if needed. This study sought to understand what factors influence anxiety and satisfaction experienced by patients undergoing BF under conscious sedation. This study had a prospective observational character and evaluated 463 consecutive patients undergoing BF. Participants were divided into two groups, those undergoing BF for the first time and those who had undergone the procedure at least once in the past. Data were collected from three questionnaires prepared by the research team. Patients who had undergone multiple bronchoscopies were more satisfied with their physician's explanation of the procedure (P < 0.0001), had a better understanding of the indications (P < 0.0001) and potential complications (P < 0.0001) of BF and knew what specific procedure was planned (P < 0.001). Patients undergoing BF for the first time experienced anxiety before the procedure more frequently (P < 0.001). No significant difference in satisfaction was observed between patient groups and 89% would agree to BF in the future. Patients who had previously undergone BF were better prepared for their procedure; however, satisfaction levels after the procedure were similar in both groups. Results suggest that medical staff should target patients who have not undergone BF previously to relieve anxiety. © 2015 John Wiley & Sons Ltd.

    Delirium is common after cardiac surgery and is independently associated with increased morbidity, mortality, prolonged hospital stays, and higher costs. Cobalamin (vitamin B12) deficiency is a common cause of neuropsychiatric symptoms and affects up to 40% of elderly people. The relationship between cobalamin deficiency and the occurrence of delirium after cardiac surgery has not been examined in previous studies. We examined the relationship between cobalamin deficiency and delirium in elderly patients undergoing coronary artery bypass grafting (CABG) surgery. A total of 100 patients with cobalamin deficiency undergoing CABG were enrolled in this retrospective study. Control group comprised 100 patients without cobalamin deficiency undergoing CABG. Patients aged 65 years or over were included. Diagnosis of delirium was made using Intensive Care Delirium Screening Checklist. Delirium severity was measured using the Delirium Rating Scale-revised-98. Patients with cobalamin deficiency had a significantly higher incidence of delirium (42% vs 26%; P=0.017) and higher delirium severity scores (16.5±2.9 vs 15.03±2.48; P=0.034) than patients without cobalamin deficiency. Cobalamin levels were significantly lower in patients with delirium than patients without delirium (P=0.004). Delirium severity score showed a moderate correlation with cobalamin levels (ρ=-0.27; P=0.024). Logistic regression analysis demonstrated that cobalamin deficiency was independently associated with postoperative delirium (OR 1.93, 95% CI 1.03-3.6, P=0.038). The results of our study suggest that cobalamin deficiency may be associated with increased risk of delirium in patients undergoing CABG. In addition, we found that preoperative cobalamin levels were associated with the severity of delirium. This report highlights the importance of investigation for cobalamin deficiency in patients undergoing cardiac surgery, especially in the elderly.

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

    The gain by performing sentinel lymph node biopsy (SLNB) during prophylactic mastectomy (PM) is debatable, and we performed a meta-analysis of existing literature to evaluate that the role of SLNB in subjects undergoing PM. A systematic search was conducted using MEDLINE, PubMed, EMBASE, Current Contents Connect, Cochrane library, Google Scholar, Science Direct, and Web of Science. The search identified 11 relevant articles reporting on patients who underwent SLNB at the time of PM. Data were abstracted from each study and used to calculate a pooled odds ratio (OR) and 95% confidence interval (95% CI). We included 14 studies comprising of 2,708 prophylactic mastectomies. Among 2,708 prophylactic mastectomies, the frequency of occult invasive cancer (51 cases) was 1.8% and the rate of positive SLNs (33 cases) was 1.2%. In 25 invasive cancers at the time of PM were found to have negative SLNs which avoided axillary lymph node dissection (ALND). In seven cases with positive SLNBs were found not to have invasive cancer at the time of PM and needed a subsequent ALND. Most of the patients with positive SLNs had locally advanced disease in the contralateral breast. SLNB may be suitable for patients with ipsilateral, locally advanced breast cancer and is not recommend for all patients undergoing PM.

    Despite growing recognition of type 2 myocardial infarction (T2MI; related to supply/demand mismatch), little is known about its risk factors or its association with outcome. A single-center cohort of patients undergoing coronary or peripheral angiography with or without intervention was prospectively enrolled and followed for incident type 1 and T2MI, and major adverse cardiovascular events (MACE, a composite of all-cause death, nonfatal myocardial infarction [MI], heart failure, stroke, transient ischemic attack, peripheral arterial complication, and cardiac arrhythmia), as well. T2MI was adjudicated using criteria from the Third Universal Definition of MI. Baseline characteristics, blood samples, and angiography information were obtained. Major end points subsequent to first MI were assessed using landmark analyses to compare the rates of first events only where everyone with a prior history of any MACE before MI were censored and adjusted for follow-up times. Cox proportional hazard models were used for time-to-event analyses with age and sex forced into all models and additional covariates evaluated by using the stepwise option for the selection. One thousand two hundred fifty-one patients were enrolled and followed for a median of 3.4 years. Of these patients, 152 (12.2%) had T2MI during follow-up; T2MI was frequently recurrent. Multivariable predictors of T2MI were older age, lower systolic blood pressure, history of coronary artery disease, heart failure, chronic obstructive pulmonary disease, diabetes mellitus, nitrate use, and elevated concentrations of glucose, N-terminal pro-B type natriuretic peptide, and cystatin C. Patients with T2MI had higher rates of subsequent adverse events than those without T2MI (per 100 person-years: MACE, 53.7 versus 21.1, P<0.001; all-cause death, 23.3 versus 3.3, P<0.001; cardiovascular death, 17.5 versus 2.6, P<0.001; heart failure events, 22.4 versus 7.4, P<0.001); these rates are similar to those seen in patients with

    Patients commonly undergo noncardiac surgical procedures after implantation of a coronary stent. In the case where surgery cannot be deferred until completing the minimum duration of dual antiplatelet therapy, the Brigham and Women's Hospital Cardiac Catheterization Laboratory recommends using a glycoprotein IIb/IIIa bridging protocol to minimize the risk of perioperative ischemic events. We discuss our algorithm for managing antiplatelet agents, including the newer agents, prasugrel and ticagrelor, in patients undergoing noncardiac surgery after coronary stenting and present our glycoprotein IIb/IIIa bridging strategy along with a review of the relevant pharmacodynamic and clinical evidence.

    Remote ischemic preconditioning (RIPC) has been shown to enhance the tolerance of remote organs to cope with a subsequent ischemic event. We hypothesized that RIPC reduces postoperative neurocognitive dysfunction (POCD) in patients undergoing complex cardiac surgery. We conducted a prospective, randomized, double-blind, controlled trial including 180 adult patients undergoing elective cardiac surgery with cardiopulmonary bypass. Patients were randomized either to RIPC or to control group. Primary endpoint was postoperative neurocognitive dysfunction 5-7 days after surgery assessed by a comprehensive test battery. Cognitive change was assumed if the preoperative to postoperative difference in 2 or more tasks assessing different cognitive domains exceeded more than one SD (1 SD criterion) or if the combined Z score was 1.96 or greater (Z score criterion). According to 1 SD criterion, 52% of control and 46% of RIPC patients had cognitive deterioration 5-7 days after surgery (p = 0.753). The summarized Z score showed a trend to more cognitive decline in the control group (2.16±5.30) compared to the RIPC group (1.14±4.02; p = 0.228). Three months after surgery, incidence and severity of neurocognitive dysfunction did not differ between control and RIPC. RIPC tended to decrease postoperative troponin T release at both 12 hours [0.60 (0.19-1.94) µg/L vs. 0.48 (0.07-1.84) µg/L] and 24 hours after surgery [0.36 (0.14-1.89) µg/L vs. 0.26 (0.07-0.90) µg/L]. We failed to demonstrate efficacy of a RIPC protocol with respect to incidence and severity of POCD and secondary outcome variables in patients undergoing a wide range of cardiac surgery. Therefore, definitive large-scale multicenter trials are needed. ClinicalTrials.gov NCT00877305.

    Background: We aimed to analyze the effect of nursing strategies on patients with chronic renal failure (CRF) undergoing maintenance hemodialysis (MHD) treatment by puncturing on arteriovenous fistula (AVF). Methods: Ninety-two patients with chronic renal failure undergoing maintenance hemodialysis (MHD) between Jan 2014 and Jan 2015 were included in the study (all undergoing AVF, dialysis for 2–3 sessions per week, 4–5 h per session) and randomly divided into control group and observation group. Patients in control group were given standard nursing care and patients in observation group were given professional nursing of internal fistula. The complication rate and dysfunction rate during internal fistula perioperative period, fistula usage time and effect on life quality of patients of these two groups were compared (during 18-month follow-up). Results: The complication rate and dysfunction rate during internal fistula perioperative period of the observation group were significantly lower than that of the control group, and the difference was statistically significant (P<0.05). The median time of internal fistula usage was significantly prolonged, and the health index, emotion index and psychology index quality-of-life in the observation group were significantly higher than that of the control group (P<0.05). Conclusion: Professional nursing strategies of internal fistula can prolong service time, decrease complications and improve life quality for patients undergoing maintenance hemodialysis treatment via arteriovenous fistula.

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

    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.

    Guidelines established preoperative cardiac management of the patient undergoing non-cardiac surgery in hospitalization. Regarding the patients undergoing the surgery in DS, the management is not defined. Aim of this study was to evaluate the appropriateness of the cardiological consultation requested by the patients undergoing surgery with this method. We examined the request of cardiological evaluation for patient admitted to DS of Sant'Andrea Hospital in Rome. We have considered: age, sex, clinic history, simpthomatology, electrocardiogram, cardiovascular objectivity, hemodynamic stability, comorbidity, therapy, type of the surgery, the motivation of the request. Of 2350 patients, 495 patients (21%) have been undergone the preoperative cardiologic consultation. The request was resulted as unnecessary for 432 (87.2%) patients, appropriate for 63 (12.7%): 4 that had the ischemic heart disease without knowing this, 6 with severe hypertension; 2 with mitral valve prolapse and valvular regurgitation; 34 with congestive heart failure; 6 with the alterations in EKG : 3 with "Brugada pattern"; 1 with Pace Maker (PMK) that had to be reprogrammed before the operation; 3 under dual antiplatelet therapy; 7 that were taking the oral anticoagulant therapy. Cardiac complications occurred just in one case with patient suffering dilated cardiomyopathy, diabetes and hypertension; during the cataract surgery was presented the abrupt increase of blood pressure and left ventricular failure. Preoperative cardiologic evaluation results as useless in most patients. However, in some particular situations had allowed the diagnosis of heart disease for the patients who did not know to have it.

    Background. Diarrhea is a common problem in ovarian cancer patients undergoing chemotherapy and Clostridium difficile infection has been identified as a cause. The proper diagnosis and treatment of diarrhea are critical to patient care, especially to prevent the serious complications from a severe Clostridium difficile infection (CDI). Case. We present a heavily pretreated ovarian cancer patient who developed recurrent pseudomembranous colitis while receiving carboplatin chemotherapy. Despite treatment with oral metronidazole for fourteen days, the patient's diarrhea relapsed and colonoscopy revealed extensive pseudomembranous colitis. The infection eventually resolved with the combination of oral vancomycin and metronidazole. Conclusions. Diarrhea is a common problem in patients undergoing chemotherapy for ovarian cancer. Management requires obtaining the proper diagnosis. Clostridium difficile associated pseudomembranous colitis must be part of the differential diagnosis. Treatment must be sufficient to prevent relapses of the Clostridium difficile infection to prevent serious consequences in an already vulnerable patient population. PMID:27051544

    2013-12-01

    A best evidence topic in cardiovascular surgery was written according to a structured protocol. The question addressed was whether administering sodium bicarbonate (NaHCO3) prevents contrast-induced nephropathy (CIN) in cardiovascular patients undergoing contrast imaging. In total, 266 papers were found using the reported search, 16 of which represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. CIN is thought to occur as a result of ischaemic or oxidative injury to the kidney. It is postulated that NaHCO3attenuates this renal damage by alkanizing renal tubular fluid thus reducing the generation of contrast-induced free radicals, which damage the kidney. Of the 16 trials, 15 recruited patients with various degrees of renal dysfunction at baseline. The benefit of using NaHCO3 was demonstrated at all stages of chronic kidney disease. Apart from four studies, 12 studies used low toxicity, low-osmolar contrast. Merten et al. published the first trial of NaHCO3 vs (saline) NaCl in preventing CIN, demonstrated a significantly lower rate in the NaHCO3 group and advocated its widespread use. Subsequent trials using the same regimen have collaborated these results. However, more recently, Gomes et al. concluded that NaHCO3 is not superior to saline-based hydration. Similarly, Brar et al. randomized 323 patients with moderate-to-severe renal insufficiency to receive either an NaHCO3 or an NaCl infusion and observed no difference in CIN rates. Two studies investigated the effects of rapid urine alkanization with bolus injections of NaHCO3 prior to contrast and found significant reductions in CIN rates compared with NaCl-treated groups. One study observed that NaCl is superior to NaHCO3, while all other studies showed a beneficial effect or no difference between NaCl- and NaHCO3-based hydration. The most recent meta

    Although digoxin has long been used to treat atrial fibrillation (AF) and heart failure (HF), its safety remains controversial. This study sought to describe digoxin use over time in patients with AF who were stratified by the presence or absence of HF, to characterize the predictors of digoxin use and initiation, and to correlate digoxin use with outcomes. Longitudinal patterns of digoxin use and its association with a variety of outcomes were assessed in a prospective outpatient registry conducted at 174 U.S. sites with enrollment from June 2010 to August 2011. Among 9,619 patients with AF and serial follow-up every 6 months for up to 3 years, 2,267 (23.6%) received digoxin at study enrollment, 681 (7.1%) were initiated on digoxin during follow-up, and 6,671 (69.4%) were never prescribed digoxin. After adjusting for other medications, heart rate was 72.9 beats/min among digoxin users and 71.5 beats/min among nonusers (p < 0.0001). Prevalent digoxin use at registry enrollment was not associated with subsequent onset of symptoms, hospitalization, or mortality (in patients with HF, adjusted hazard ratio [HR] for death: 1.04; without HF, HR: 1.22). Incident digoxin use during follow-up was not associated with subsequent death in patients with HF (propensity adjusted HR: 1.05), but was associated with subsequent death in those without HF (propensity adjusted HR: 1.99). After adjustment for detailed clinical factors, digoxin use in registry patients with AF had a neutral association with outcomes under most circumstances. Because of the multiple conflicting observational reports about digoxin's safety and possible concerns in specific clinical situations, a large pragmatic trial of digoxin therapy in AF is needed.

    Although strong volume-outcome relationships exist for many cancer operations, patients continue to undergo these operations at low-volume hospitals. Patients were identified from the National Cancer Data Base from 2010-2013 who underwent resection for bladder, breast, esophagus, lung, pancreas, rectum, and stomach cancers. Low-volume hospitals were defined as those in the bottom quartile by surgical volume for each cancer type separately. Logistic regression models were constructed to assess patient-level factors associated with undergoing cancer surgery at low-volume hospitals across cancer types while controlling for tumor characteristics. Survival outcomes (30- and 90-day mortality; overall survival) were also assessed. Low volume thresholds were 4, 84, 4, 18, 8, 7, and 4 resections per year for bladder, breast, esophagus, lung, pancreas, rectum, and stomach cancers, respectively, resulting in 772 (74.1%), 828 (57.5%), 664 (77.5%), 830 (64.7%), 716 (79.2%), 898 (65.1%), and 888 (68.5%) hospitals classified as low-volume hospitals, respectively. For all the cancers examined, patients were more likely to undergo operation at low-volume hospitals if they traveled shorter distances (home to surgical facility), resided in rural locations, or had not received neoadjuvant therapy. Other patient and tumor factors were not associated consistently with undergoing operation at low-volume hospitals. Patients who went to low-volume hospitals had poorer outcomes among the studied cancers. Patients continue to undergo operation at low-volume hospitals due to where they live and how far they have to travel. Regionalization policy initiatives will remain challenging in this population. Efforts should therefore continue to emphasize quality improvement locally at each facility caring for patients with cancer. Copyright © 2016 Elsevier Inc. All rights reserved.

    The incidence of severe limb ischemia (SLI) is high among haemodialysis (HD) patients. Limb rescue rate after surgical revascularization is relatively poor compared with patients with normal renal function. Prostanoids are an interesting category as adjuvants to revascularization. New vessel growth develops not exclusively by proliferation of endothelial cells in vascular extremities but also by cells mobilized from the bone marrow (HSC), transformed into endothelial progenitor cells (EPC) contributing to both re-endothelialization and neovascularization. Basal number of HSC and EPC is significantly reduced in HD patients and correlated with a subsequent defective neovascularization. The aim of this study was to evaluate the effects of perioperative treatment with iloprost in uremic patients with acute ischemia of lower limbs, undergoing surgical revascularization, on endothelial progenitor cells, hypothesizing a possible biological mechanism induced by the prostanoids. A search was also made for vascular remodeling processes through the analysis of the concentrations of soluble adhesion molecules (i-CAM, v-CAM, e-selectin), biochemical markers of endothelial activation. Thirty HD patients with SLI undergoing peripheral revascularization were enrolled (15 were treated with iloprost and 15 with a placebo). Iloprost was administered as an intra-arterial bolus of 3000 ng over 1 to 3 min immediately after revascularization and in the same affected artery. Serum samples were taken before revascularization (T0), at 6 (T6) and 24 h (T24) after infusion to measure sICAM-1, sE-selectin, and sVCAM-1, and for quantification of HSC and EPC. Progenitors were identified by specific surface markers CD34+, CD133+ and VEGFR2+. Count was conducted using PROCOUNT performed in a TRUCOUNT tube and with a FACSort flow cytometer. Before revascularization, all patients showed a decreased number of HSC and EPC. After 6 h, HSC augmented significantly compared with T0 in both groups. The

    Purpose To assess patient navigation (PN) utilization and its impact on treatment interruptions and clinical trial enrollment among American Indian (AI) cancer patients. Methods Between February 2004 and September 2009, 332 AI cancer patients received PN services throughout cancer treatment. The PN program provided culturally-competent navigators to assist patients with navigating cancer therapy, obtaining medications, insurance issues, communicating with medical providers, and travel and lodging logistics. Data on utilization and trial enrollment were prospectively collected. Data for a historical control group of 70 AI patients who did not receive PN services were used to compare treatment interruptions among those undergoing PN during curative radiation therapy (subgroup of 123 patients). Results The median number of contacts with a navigator was 12 (range, 1-119). The median time spent with the navigator at first contact was 40 minutes (range 10-250 min.) and 15 min for subsequent contacts. Patients treated with radiation therapy with curative intent who underwent PN had fewer days of treatment interruption (mean, 1.7 days; 95% CI, 1.1-2.2 days) than historical controls who did not receive PN services (mean, 4.9 days; 95% CI, 2.9-6.9 days). Of the 332 patients, 72 (22%; 95% CI, 17-26%) were enrolled on a clinical treatment trial or cancer control protocol. Conclusions PN was associated with fewer treatment interruptions and relatively high rates of clinical trial enrollment among AI cancer patients compared to national reports. PMID:21656754

    Aim. The study assessed the usefulness of a recently developed method for respiratory rate (RR) monitoring in patients undergoing endoscopic submucosal dissection (ESD) under deep sedation. Methods. Study subjects comprised 182 consecutive patients with esophageal cancer or gastric cancer undergoing ESD. The usefulness of acoustic RR monitoring was assessed by retrospectively reviewing the patients' records for age, gender, height, weight, past history, serum creatinine, RR before ESD, and total dose of sedative. Results. Respiratory suppression was present in 37.9% of (69/182) patients. Continuous monitoring of RR led to detection of respiratory suppression in all these patients. RR alone was decreased in 24 patients, whereas both RR and blood oxygen saturation were decreased in 45 patients. Univariate analysis showed female gender, height, weight, and RR before treatment to be significantly associated with respiratory suppression. Multivariate analysis showed RR before treatment to be the only significant independent predictor [odds ratio (OR) 0.83, 95% confidence interval (CI) 0.73–0.95, and P = 0.006] of respiratory suppression. Conclusion. In this study, the difference in RR before treatment between patients with and without respiratory suppression was subtle. Therefore, we suggest that acoustic RR monitoring should be considered in patients undergoing ESD under sedation to prevent serious respiratory complications. PMID:26858748

    Purpose Sleep-disordered breathing (SDB) is often associated with other medical disorders. Whether SDB interacts with other factors for developing subsequent epilepsy remains unclear. Methods This population-based cohort study was conducted using the National Health Insurance Research Database of Taiwan. Patients aged >20 years and diagnosed with SDB between 2000 and 2010 comprised the SDB cohort (n = 138,507), and their data were compared with those of the comparison cohort (n = 138,507). The adjusted hazard ratio (aHR) for epilepsy was calculated using a multivariate Cox proportional hazards model. Results The SDB cohort had an increased risk of epilepsy (aHR = 1.50, 95% confidence interval [CI] = 1.36–1.66). The sex-stratified analysis revealed a significant adjusted hazard ratio (aHR) for epilepsy with a 1.51-fold higher risk for female patients, and also a significantly 1.49-fold higher risk for male patients in the SDB cohort. Although epilepsy incidence increased with age in both cohorts, different age groups in the SDB cohort all had a significantly higher risk of developing epilepsy than comparison cohort. Conclusion This population-based cohort study indicates that patients with SDB are at a high risk of developing subsequent epilepsy, in both sexes and all age groups. PMID:28291799

    Calcific uremic arteriolopathy, also known as calciphylaxis, is a rare syndrome of small vessel calcification of unknown etiology causing painful, violaceous skin lesions that progress to form chronic non-healing ulcers and gangrene. Hyperbaric oxygen therapy (HBOT) can be used as adjunctive therapy in the treatment of these ulcers. However, due to paucity of cases, there is limited data on the clinical benefit of HBOT and identifying factors associated with healing. The purpose of this study was to determine patient outcomes and factors associated with healing in patients with calciphylaxis undergoing HBOT. A retrospective chart review was completed on patients who were diagnosed with calciphylaxis and had hyperbaric medicine consultation between May 2012 and January 2016. Clinical outcomes, demographics, risk factors, laboratory values, wound distribution, and HBOT profiles were collected and analyzed. We identified 8 patients. Out of 8 patients consulted for calciphylaxis, five were consented and underwent HBOT (2 males and 3 females). All had coexisting ESRD and Diabetes. All males were able to tolerate being in the chamber and received therapeutic treatments (at least 20 HBOT) with complete resolution of ulcers. HBOT was discontinued in one female due to an inconsistent biopsy report and two others due to death secondary to septic shock or respiratory arrest and severe uremia. Calciphylaxis is a devastating disease with a high mortality rate. Our results demonstrated a positive response to HBOT especially when receiving at least 20 treatments. A majority of calciphylaxis cases are females and indeed female gender has been cited as a risk factor for this disease. However, current literature has not conferred a relationship between gender nor the number of HBOT received and outcomes. Our results showed that males had a more favorable outcome provided they received at least twenty HBOT. Further prospective studies are needed to elucidate these outcomes.

    Background Ethnic minority adults have disproportionately higher rates of obesity than Caucasians but are less likely to undergo bariatric surgery. Recent data suggest that minorities might be less likely to seek surgery. Whether minorities who seek surgery are also less likely to proceed with surgery is unclear. Methods We interviewed 651 patients who sought bariatric surgery at two academic medical centers to examine whether ethnic minorities are less likely to proceed with surgery than Caucasians and whether minorities who do proceed with surgery have higher illness burden than their counterparts. We collected patient demographics and abstracted clinical data from the medical records. We then conducted multivariable analyses to examine the association between race and the likelihood of proceeding with bariatric surgery within 1 year of initial interview and to compare the illness burden by race and ethnicity among those who underwent surgery. Results Of our study sample, 66 % were Caucasian, 18 % were African-American, and 12 % were Hispanics. After adjustment for socioeconomic factors, there were no racial differences in who proceeded with bariatric surgery. Among those who proceeded with surgery, illness burden was comparable between minorities and Caucasian patients with the exception that African-Americans were underrepresented among those with reflux disease (0.4, 95 % CI 0.2–0.7) and depression (0.4, 0.2–0.7), and overrepresented among those with anemia (4.8, 2.4–9.6) than Caucasian patients. Conclusions Race and ethnicity were not independently associated with likelihood of proceeding with bariatric surgery. Minorities who proceeded with surgery did not clearly have higher illness burden than Caucasian patients. PMID:25492453

    Background Decision-making processes have been posited to affect treatment outcome in addicted patients. Objective The present multi-site study assessed whether two measures of decision-making predicted relapse and subsequent use in stimulant-dependent patients. Methods 160 methamphetamine- or cocaine-dependent patients participating in a multi-site clinical trial evaluating a modified 12-step facilitation intervention for stimulant-dependent patients (STAGE-12) were assessed. Decision-making processes of risk and delay [Iowa Gambling Task (IGT)] and response reversal [Wisconsin Card Sorting Task (WCST)] were obtained shortly after treatment admission followed by assessment of stimulant use over the next six months. The relationships of the IGT and WCST (Perseverative Errors) with relapse (yes/no) and days of stimulant use during the 6-month period following post-randomization were evaluated. Results Performance on the IGT and WCST did not significantly predict relapse status or time to relapse. Unexpectedly, better performance on the IGT was associated with a fewer number of stimulant use days (p = 0.001). In contrast, worse performance on the WCST (more perseverative errors) was associated with a greater number of stimulant use days (p = 0.0003). The predictive effects of perseverative errors on subsequent use were confined to methamphetamine-dependent and Minority participants. Conclusions Decision-making processes, as measured in the current study, do not uniformly predict relapse or subsequent use. A decrease in the salience attribution of nondrug reinforcers may explain the positive relationship between IGT performance and post-relapse use. More comprehensive and global measures of impulsiveness may better assess relapse risk and use. PMID:26743586

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

    Objective: 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.

    Context Patients with mental disorders show higher burden of coronary heart disease, and may face special safety issues during in-hospital cardiac care. Objectives To compare the postoperative complication rate between patients with and without mental disorders undergoing isolated coronary artery bypass graft (CABG) surgery. Design, Setting, and Patients Retrospective analyses of New York state hospital claims between 1997 and 2004 (N=135,701). Complications were defined using the Agency for Healthcare Research and Quality Patient Safety Indicators (AHRQ PSI). Principal Findings Mental disorders were significantly associated with higher anesthesia complications (adjusted odds ratio [AOR]=6.44, p<.001), decubitus ulcer (AOR=1.42, p=.006), postoperative hip fracture (AOR=3.29, p<.001), and overall complication rate representing nine PSIs (AOR=1.27, p<.001). Conclusions Mentally ill patients undergoing CABG surgery are more likely to experience potentially preventable complications and injuries. The mechanism underlying this observation warrants further study. PMID:18665856

    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 measured the antioxidant activity of follicular fluid (FF) in infertile patients and assessed its possible correlation between ovarian stimulation and pregnancy outcomes. Samples from 191 infertile patients undergoing in vitro fertilization-embryo transfer (IVF-ET) were determined by α-diphenyl-β-picrylhydrazyl (DPPH) radical scavenging, reducing power, superoxide radical scavenging, β-Carotene bleaching assay, ferrothiocyanate and thiobarbituric acid assays. The comparison between a positive IVF outcome and FF’s antioxidant activity was also studied. The results showed FF had strong antioxidant activity, which equated to common antioxidants Vc and BHT (100 μg/mL). Patients with endometriosis had less efficient antioxidant activity in FF than that of patients with tubal occlusion or polycystic ovary syndrome. In conclusion, this study detected, for the first time, the antioxidant activity of FF from patients undergoing an IVF and the FF exhibited strong antioxidant activity. PMID:24966936

    Introduction Outcomes for patients undergoing intervention for restenosis after prior ipsilateral carotid endarterectomy (CEA) in the era of carotid stenting (CAS) are unclear. We compared perioperative results and durability of CAS versus CEA in patients with symptomatic or asymptomatic restenosis after prior CEA and investigated the risk of re-intervention compared to primary procedures. Methods Patients undergoing CAS and CEA for restenosis between January 2003 and March 2012 were identified within the Vascular Study Group of New England (VSGNE) database.Endpoints included any stroke, death or myocardial infarction (MI) within 30 days, cranial nerve injury at discharge and restenosis ≥70% at 1-year follow-up. Multivariable logistic regression was done to identify whether prior ipsilateral CEA was an independent predictor for adverse outcome. Results Out of 9305 CEA procedures, 212 patients (2.3%) underwent redo-CEA (36% symptomatic). Of 663 CAS procedures, 220 patients (33%) underwent CAS after prior ipsilateral CEA (31% symptomatic). Demographics of patients undergoing redo-CEA were comparable to patients undergoing CAS after prior CEA. Stroke/death/MI rates were statistically similar between redo-CEA vs CAS after prior CEA in both asymptomatic (4.4% vs 3.3%, P=0.8) and symptomatic patients (6.6% vs 5.8%, P=1.0). No significant difference in restenosis ≥70% was identified between redo-CEA and CAS after prior CEA (5.2% vs. 3.0%, P = 0.5). Redo-CEA vs primary CEA had increased stroke/death/MI rate in both symptomatic (6.6% vs 2.3%, P=0.05) and asymptomatic patients 4.4% vs 1.7%, P=0.03). Prior ipsilateral CEA was an independent predictor for stroke/death/MI among all patients undergoing CEA (OR 2.1, 95% CI 1.3 – 3.5). No difference in cranial nerve injury was identified between redo-CEA and primary CEA (5.2% vs 4.7%, P=0.8). Conclusions In the VSGNE, CEA and CAS showed statistically equivalent outcomes in asymptomatic and symptomatic patients treated for

    In patients undergoing off-pump coronary artery bypass surgery (OPCAB), it is important to attenuate myocardium injury during the surgery. The present study aimed to observe the cardioprotection induced by sevoflurane induction and maintenance compared with propofol intravenous anesthesia, and to detect its potential protection against acute myocardial injury with sensitive biomarkers. In total, 36 patients undergoing OPCAB were randomly assigned into two groups, receiving sevoflurane (n=18) or propofol (n=18) as the induction and maintenance anesthetic agent. The depth of anesthesia in the two groups was kept at a bispectral index value of 40-50. Physiological and hemodynamic parameters were recorded during the surgery. Cardiac troponin-I (cTnI), creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH) and two microRNAs (miR-499 and miR-208b) were also measured during and subsequent to surgery. Nno statistically significant differences were observed in the physiological and hemodynamic parameters between the two groups prior to surgery. Following surgery, the cardiac output and stroke volume improved significantly in the sevoflurane group (P<0.05). In addition, patients in the sevoflurane group had lower miR-499 (P<0.05) and miR-208b (P<0.01) levels at 12 h after surgery when compared with the propofol group. However, no significant differences in cTnI, CK-MB and LDH levels were observed following surgery between the two groups. In conclusion, volatile induction and maintenance with sevoflurane resulted in some extent of cardiac function improvement in patients undergoing OPCAB. Cardioprotection by sevoflurane is suggested by reduced cardiac injury compared with propofol, and indicated by the sensitive biomarkers, circulating miR-499 and miR-208b.

    Stereotactic radiosurgery was originally introduced by Lars Leksell in 1951. This treatment refers to the noninvasive destruction of an intracranial target localized stereotactically. The purpose of this study was to identify the dose delivered to the parotid, ovaries, testis and thyroid glands during the Gamma Knife radiosurgery procedure. A three-dimensional, anthropomorphic phantom was developed using natural human bone, paraffin and sodium chloride as the equivalent tissue. The phantom consisted of a thorax, head and neck and hip. In the natural places of the thyroid, parotid (bilateral sides) and ovaries (midline), some cavities were made to place TLDs. Three TLDs were inserted in a batch with 1 cm space between the TLDs and each batch was inserted into a single cavity. The final depth of TLDs was 3 cm from the surface for parotid and thyroid and was 15 cm for the ovaries. Similar batches were placed superficially on the phantom. The phantom was gamma irradiated using a Leksell model C Gamma Knife unit. Subsequently, the same batches were placed superficially over the thyroid, parotid, testis and ovaries in 30 patients (15 men and 15 women) who were undergoing radiosurgery treatment for brain tumours. The mean dosage for treating these patients was 14.48 +/- 3.06 Gy (10.5-24 Gy) to a mean tumour volume of 12.30 +/- 9.66 cc (0.27-42.4 cc) in the 50% isodose curve. There was no significant difference between the superficial and deep batches in the phantom studies (P-value < 0.05). The mean delivered doses to the parotid, thyroid, ovaries and testis in human subjects were 21.6 +/- 15.1 cGy, 9.15 +/- 3.89 cGy, 0.47 +/- 0.3 cGy and 0.53 +/- 0.31 cGy, respectively. The data can be used in making decisions for special clinical situations such as treating pregnant patients or young patients with benign lesions who need radiosurgery for eradication of brain tumours.

    Percutaneous transfemoral transcatheter aortic valve implantation (TF-TAVI) is generally an acceptable procedure but may be associated with vascular complications at femoral access sites, particularly in obese patients. This report aimed to describe a case of successful performance of our "double crossover technique" in an obese patient undergoing TF-TAVI with a percutaneous transfemoral intra-aortic balloon pump (TF-IABP). A 75-year-old man presented with heart failure due to a left ventricular ejection fraction of 35% and low-flow, low-gradient severe aortic stenosis. The logistic EuroSCORE and STS-PROM score were 31.38% and 7.311%, respectively. Right TF-TAVI using a 14-Fr expandable sheath and a left TF-IABP using an 8-Fr sheath were scheduled. The patient was obese, with a body mass index of 31.7kg/m(2), and we expected access site-related vascular complications to occur. Subsequently, we performed a femoral and brachial crossover technique, called the "double crossover technique," at the completion of the TAVI procedure: first, for the right common femoral artery (CFA) through the sheath in the left CFA and second, for the left CFA through the sheath in the right brachial artery. In the crossover technique, an 8.0-mm-diameter over-the-wire balloon was advanced to an external iliac artery and was subsequently inflated when the sheath was removed. For the right CFA, a double preclose technique was used with the crossover technique. There was no evidence of access site-related vascular complications following TAVI. The double crossover technique was effective at achieving hemostasis and avoiding access site-related vascular complications in an obese patient undergoing TF-TAVI with a TF-IABP.

We aimed to assess whether TGF-β1 signaling is affected by age. Methods Vascular smooth muscle cells (VSMC) were obtained from patients undergoing abdominal surgery. Levels of TGF-β1 were measured by ELISA in sera from 169 patients undergoing coronary artery bypass grafting (CABG). The p27 expression was determined by Western blot from internal mammary arteries (IMA) obtained from CABG patients (n = 13). In VSMC from these patients undergoing abdominal surgery, secretion of TGF-β1 was determined by ELISA of cell-conditioned media. Results In VSMC from aged patients we observed a lower TGF-β1 secretion, measured as TGF-β1 concentration in cell conditioned medium (p < 0.001). This effect was correlated to an age-dependent decrease of p27 expression in IMA from aged CABG patients. In a similar manner, there was an age-dependent decrease of serum TGF-β1 levels in CABG patients (p = 0.0195). Conclusions VSMC from aged patients showed a higher degree of cellular senescence and it was associated to a lower TGF-β1 secretion and signaling. PMID:24495866

    Little is known about how patients undergoing stem cell transplantation (HCT) and their family caregivers (FC) perceive their prognosis. We examined prognostic understanding in patients undergoing HCT and their FC and its relationship with quality of life (QOL) and mood. We conducted a longitudinal study of patients (and FC) hospitalized for HCT. We used a questionnaire to measure participants’ prognostic understanding and asked the oncologists to estimate patients’ prognosis prior to HCT. We assessed QOL and mood weekly and evaluated the relationship between prognostic understanding and QOL and mood using multivariable linear mixed models. We enrolled 90 patients undergoing (autologous n=30); myeloablative (n=30) or reduced intensity allogeneic (n=30)) HCT. 88.9% of patients and 87.1% of FC reported it is ‘extremely’ or ‘very’ important to know about prognosis. However, 77.6% of patients and 71.7% of FC reported a discordance and more optimistic prognostic perception compared to the oncologist (P’s < 0.0001). Patients with a concordant prognostic understanding with their oncologists reported worse QOL (β = −9.4, P = 0.01) and greater depression at baseline (β = 1.7, P = 0.02) and over time ((β = 1.2, P < 0.0001). Therefore, Interventions are needed to improve prognostic understanding, while providing patients with adequate psychological support. PMID:25961772

    Capsule endoscopy (CE) of the small bowel has become a standard diagnostic tool, but there have been concerns regarding the risk of capsule retention in certain high-risk groups. The Agile patency system, an ingestible and dissolvable capsule with an external scanner, was developed to allow physicians to perform CE with greater confidence that the capsule will be safely excreted in patients at risk for capsule retention. Our purpose was to assess the ability of the device to help physicians identify which patients with known strictures may safely undergo CE. Patients with known strictures ingested the new patency capsule and underwent periodic scanning until it was excreted. The intestinal tract was considered to be sufficiently patent if the capsule was excreted intact or if the capsule was not detected by the scanner at 30 hours after ingestion. If patency was established, then standard CE was performed. International multicenter study. A total of 106 patients with known strictures. Agile patency system. Performance and safety of Agile patency system. A total of 106 patients ingested the patency capsule. Fifty-nine (56%) excreted it intact and subsequently underwent CE. There were no cases of capsule retention. Significant findings on CE were found in 24 (41%). There were 3 severe adverse events. These results suggest that the Agile patency system is a useful tool for physicians to use before CE in patients with strictures to avoid retention. This group of patients may have a high yield of clinically significant findings at CE. This capsule may determine whether patients who have a contraindication to CE may safely undergo CE and obtain useful diagnostic information.

    The emergence of the threat of radiological terrorism and other radiological incidents has led to the need for development of fast, accurate and noninvasive methods for detection of radiation exposure. The purpose of this study was to extend radiation metabolomic biomarker discovery to humans, as previous studies have focused on mice. Urine was collected from patients undergoing total body irradiation at Memorial Sloan-Kettering Cancer Center prior to hematopoietic stem cell transplantation at 4–6 h postirradiation (a single dose of 1.25 Gy) and 24 h (three fractions of 1.25 Gy each). Global metabolomic profiling was obtained through analysis with ultra performance liquid chromatography coupled to time-of-flight mass spectrometry (TOFMS). Prior to further analyses, each sample was normalized to its respective creatinine level. Statistical analysis was conducted by the nonparametric Kolmogorov-Smirnov test and the Fisher’s exact test and markers were validated against pure standards. Seven markers showed distinct differences between pre- and post-exposure samples. Of those, trimethyl-l-lysine and the carnitine conjugates acetylcarnitine, decanoylcarnitine and octanoylcarnitine play an important role in the transportation of fatty acids across mitochondria for subsequent fatty acid β-oxidation. The remaining metabolites, hypoxanthine, xanthine and uric acid are the final products of the purine catabolism pathway, and high levels of excretion have been associated with increased oxidative stress and radiation induced DNA damage. Further analysis revealed sex differences in the patterns of excretion of the markers, demonstrating that generation of a sex-specific metabolomic signature will be informative and can provide a quick and reliable assessment of individuals in a radiological scenario. This is the first radiation metabolomics study in human urine laying the foundation for the use of metabolomics in biodosimetry and providing confidence in biomarker

    Background Knowledge about the impact of Low-Molecular-Weight Heparin (LMWH) on the coagulation system in patients undergoing minimal invasive lung cancer surgery is sparse. The aim of this study was to assess the effect of LMWH on the coagulation system in patients undergoing Video-Assisted Thoracoscopic Surgery (VATS) lobectomy for primary lung cancer. Methods Sixty-three patients diagnosed with primary lung cancer undergoing VATS lobectomy were randomized to either subcutaneous injection with dalteparin (Fragmin®) 5000 IE once daily or no intervention. Coagulation was assessed pre-, peri-, and the first two days postoperatively by standard coagulation blood test, thromboelastometry (ROTEM®) and thrombin generation. Results Patients undergoing potential curative surgery for lung cancer were not hypercoagulable preoperatively. There was no statistically significant difference in the majority of the assessed coagulation parameters after LMWH, except that the no intervention group had a higher peak thrombin and a shorter INTEM clotting time on the first postoperative day and a lower fibrinogen level on the second postoperative day. A lower level of fibrin d-dimer in the LMWH group was found on the 1. and 2.postoperative day, although not statistical significant. No differences were found between the two groups in the amount of bleeding or number of thromboembolic events. Conclusions Use of LMWH administered once daily as thromboprophylaxis did not alter the coagulation profile per se. As the present study primarily evaluated biochemical endpoints, further studies using clinical endpoints are needed in regards of an optimized thromboprophylaxis approach. PMID:28199364

    Nutritional risk and malnutrition was significantly higher in patients undergoing gastrointestinal surgery as compared to patients in other surgical departments, especially in elder patients, which would directly impact on the efficacy, cost and prognosis. Nutritional screening and assessment should be performed within 24-48 hours after admission. Patients at high risk of malnutrition should be planned with early nutrition support. The best nutrition route should be determined to improve the outcomes of surgery and nutritional support, reduce the complications, length of hospital stay and healthcare costs, and improve the quality of life in patients.

    Bleeding is a potentially serious complication of aortic surgery. We report our experience with the use of a periaortic bovine pericardial baffle to control intractable intraoperative bleeding. All patients who underwent aortic root, ascending, or arch replacements between January 2002 and April 2013 were reviewed. A bovine pericardial periaortic baffle was created to shunt shed blood into the right atrium. The transverse sinus was sutured closed in patients undergoing primary sternotomy. Baffle recipients were compared with the remaining patients undergoing aortic surgery. The Fisher exact test was used to determine statistical significance for categoric variables. Continuous variables were compared using the nonparametric Wilcoxon rank-sum test. All factors with a P value less than .2 were considered for multivariate logistic regression to determine independent associations with baffle use. A total of 413 patients were identified, of whom 23 received a baffle. Operative mortality for patients receiving a baffle was 4% (1/23) compared with 6% (25/390) (P = 1) for the remaining patients. Prolonged ventilation was more common in the baffle recipients (P < .0005); otherwise, there were no differences in postoperative morbidity. Multivariate analysis of all patients undergoing aortic surgery revealed infectious endocarditis (P < .0005; odds ratio, 15.1; 95% confidence interval, 4.8-47.2), redo sternotomy (P < .0005; odds ratio, 11.9; 95% confidence interval, 4.1-34.1), and male gender (P = .04; odds ratio, 4.6; 95% confidence interval, 1.1-19.3) to be predictive of baffle placement. Patients requiring salvage periaortic pericardial baffle for intractable intraoperative hemorrhage experienced an operative mortality similar to that in the remaining patients undergoing aortic surgery. Infectious endocarditis requiring root replacement or reoperative aortic surgery should alert the surgeon to the potential need for baffle placement, including prophylactic

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

    Objective The aim of this study was to establish the number of unnecessary preoperative blood tests undertaken on ASA Grade 1 patients undergoing minor/moderate orthopaedic trauma surgery. Design Review of all ASA1 patients who had been operated on the trauma lists for three consecutive months. Setting UK Teaching Hospital. Participants Patients with ages ranging between 16 and 60 years, and undergoing a minor or moderate trauma operation. Main outcome measures The type and number of blood tests were established and any abnormal results were checked for clinical significance and whether the result altered patients' management. The cost of each blood test was calculated so that potential savings could be identified. Results A total of 127 patients (60 males, 67 females, average age 34) fulfilled our inclusion criteria. Ninety-five patients (75%) had either one or more preoperative blood tests of which 41% were abnormal but of no clinical significance. Conclusion From the results of our study, we conclude that preoperative blood tests are unnecessary in Grade 1 ASA patients undergoing minor/moderate orthopaedic trauma surgery. Unnecessary blood tests can waste time, money, resources and overburden laboratory staff. PMID:22768373

    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 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. 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. 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. 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.

    Patients with atrial fibrillation who have risk factors for thromboembolism benefit from chronic oral anticoagulation therapy, and antiplatelet therapy alone is of relatively little benefit for prevention of ischemic stroke and systemic embolism. Patients undergoing percutaneous coronary intervention with drug-eluting stents require dual antiplatelet therapy with aspirin and a thienopyridine for 3 to 12 months or more prevention of stent thrombosis and recurrent ischemic events. When patients with atrial fibrillation undergo percutaneous coronary intervention, the need to combine dual antiplatelet therapy and warfarin raises the risk of major bleeding complications considerably. Recent trials have explored the option of omitting aspirin with promising results. The introduction of novel oral anticoagulants that specifically inhibit factor IIa (dabigatran) or factor Xa (rivaroxaban, apixaban, and edoxaban) and antiplatelet agents that inhibit the P(2)Y(12) receptor (prasugrel and ticagrelor) makes management of these patients even more challenging, but future trials addressing myriad alternative regimens may identify better tolerated strategies.

    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.

    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.

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

    BACKGROUND Although digoxin has long been used to treat atrial fibrillation (AF) and heart failure (HF), its safety remains controversial. OBJECTIVES This study sought to describe digoxin use over time in patients with AF stratified by presence or absence of HF; characterize predictors of digoxin use and initiation; and correlate digoxin use with outcomes. METHODS Longitudinal patterns of digoxin use and its association with a variety of outcomes were assessed in a prospective outpatient registry conducted at 174 U.S. sites with enrollment from June 2010 to August 2011. RESULTS Among 9,619 patients with AF and serial follow-up every 6 months for up to 3 years, 2,267 (23.6%) were receiving digoxin at study enrollment, 681 (7.1%) were initiated on digoxin during follow-up, and 6,671 (69.4%) were never prescribed digoxin. Adjusting for other medications, heart rate was 72.9 beats/min among digoxin users and 71.5 among nonusers (p < 0.0001). Prevalent digoxin use at registry enrollment was not associated with subsequent onset of symptoms, hospitalization, or mortality (in patients with HF, adjusted hazard ratio [HR] for death: 1.04; without HF, HR: 1.22). Incident digoxin use during follow-up was not associated with subsequent death in patients with HF (propensity-adjusted HR: 1.05) but was in those without HF (propensity-adjusted HR: 1.99). CONCLUSIONS After adjustment for detailed clinical factors, digoxin use in registry patients with AF had a neutral association with outcomes under most circumstances. Given multiple conflicting observational reports about digoxin’s safety and possible concerns in specific clinical situations, a large pragmatic trial of digoxin therapy in AF is needed.

    Studies have found conflicting evidence regarding the association of hypoglycemia with dementia. We evaluated an association of hypoglycemia with subsequent dementia in patients with type 2 diabetes. This retrospective longitudinal cohort study used the Clinical Practice Research Datalink, an electronic medical records data from the United Kingdom, from 2003 to 2012. We included patients aged >65 years diagnosed with type 2 diabetes, with no prior diagnosis of dementia. Dementia was defined using diagnosis codes from medical records. All patients were followed from the date of initial diabetes diagnosis. To account for competing risk of death, we used Fine and Gray's competing risk model to determine the association of hypoglycemia with dementia while adjusting for potential confounders. Hypoglycemia was modeled as a time-dependent covariate. Of 53,055 patients, 5.7% (n = 3,018) had at least one hypoglycemia episodes. The overall incidence rate of dementia was 12.7 per 1,000 person-years. In the fully adjusted model that controlled for all confounders, the occurrence of at least one hypoglycemia episode was associated with 27% higher odds of subsequent dementia (hazard ratio = 1.27; 95% confidence interval = 1.06-1.51). The risk increased with the number of hypoglycemia episodes: one episode (hazard ratio = 1.26; 95% confidence interval = 1.03-1.54); two or more episodes (hazard ratio = 1.50; 95% confidence interval = 1.09-2.08). Hypoglycemia is associated with a higher risk of dementia and may be responsible in part for the higher risk of dementia in patients with diabetes. Alternatively, hypoglycemia may be a marker for undiagnosed cognitive impairment, and we cannot rule out the possibility of reverse causation between hypoglycemia and dementia.

    Although growing evidence suggests the beneficial effects of a nerve-sparing (NS) approach to surgery in cervical cancer patients, only limited data on NS laparoscopic radical hysterectomy (LRH) are available, and no studies have investigated the effects of NS-LRH on sexual function. This study aims to determine whether the implementation of NS-LRH impacts on sexual function in cervical cancer patients. Sexually active cervical cancer patients undergoing type C (class III) LRH between 2004 and 2013 were enrolled in this prospective study. Preoperative and postoperative sexual function were assessed using a validated questionnaire, the Female Sexual Function Index (FSFI). The FSFI evaluates desire, arousal, lubrication, orgasm, satisfaction, and pain. Forty patients undergoing radical hysterectomy (20 conventional LRH vs. 20 NS-LRH) represented the study group. Baseline characteristics were similar between groups (P > 0.05). No differences in preoperative FSFI scores were recorded (P > 0.05). We observed that both LRH and NS-LRH worsened postoperative FSFI scores (P < 0.001). However, patients undergoing NS-LRH had higher postoperative FSFI scores than patients undergoing LRH (21.3 ± 9.4 vs. 14.2 ± 12.5; P = 0.04). Considering postoperative domain scores, we observed that desire, arousal, orgasm, and pain scores were similar between groups (P > 0.05), while patients undergoing NS-LRH experienced higher lubrication (3.4 ± 2.3 vs. 1.7 ± 2.2; P = 0.02) and satisfaction (4.6 ± 3.9 vs. 2.8 ± 2.2; P = 0.004) scores in comparison with patients undergoing conventional LRH. No between-group differences in survival outcomes were found. Both conventional LRH and NS-LRH impact negatively on patients' sexual function. However, the NS approach impairs sexual function less, minimizing the effects of radical surgery. © 2014 International Society for Sexual Medicine.

    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.

    Cirrhosis caused by alcohol-associated liver disease is a common indication for liver transplantation worldwide. Patients with alcohol-associated liver disease who undergo liver transplantation face multiple challenging comorbid medical issues that enhance the potential for perioperative and postoperative complications. Awareness of these issues and appropriate therapeutic intervention may minimize the negative effect of these complications on posttransplantation survival. This article reviews important posttransplantation problems in patients transplanted for alcohol-associated liver disease.

    Importance Although bariatric surgery is the most cost-effective treatment for severe obesity, less than 1% of severely obese patients undergo it. Reasons for low utilization are unclear. Objectives To identify patient and referring provider characteristics associated with the likelihood of undergoing bariatric surgery. Evidence Review PubMed, PsycINFO, CINAHL, and the Cochrane databases were searched for reports published between January 1, 1998, and December 31, 2014. Reports were eligible if they presented descriptive data regarding facilitators or barriers to bariatric surgery or if they reported statistical associations between patient or provider characteristics and referral to or receipt of bariatric surgery. Frequency effect sizes were calculated as the proportion of studies reporting a finding. Findings Of the 7,212 reports identified in the initial search, 53 were included in full-text review. Nine reports met our inclusion criteria and were included in analyses. Of those, four included descriptive findings, six reported statistical associations, and one included both. One report included providers as study participants, whereas eight included patients. Four of nine studies identified an association between female gender and a greater willingness to undergo bariatric surgery. Lack of knowledge about bariatric surgery was a barrier in two studies. Five of nine cited patient concerns about the outcomes and safety of bariatric surgery as a barrier to undergoing it. Patients were more likely to pursue bariatric surgery when it was recommended by referring providers. Providers who believed that obesity treatment should be covered by insurance were more likely to recommend bariatric surgery. Conclusions and Relevance Limited patient and referring provider knowledge about the safety and effectiveness of bariatric surgery are important barriers to bariatric surgery utilization. Future efforts focused on improving knowledge and identification of the critical

    Background The impact of levosimendan treatment on clinical outcome in patients undergoing extracorporeal membrane oxygenation (ECMO) support after cardiovascular surgery is unknown. We hypothesized that the beneficial effects of levosimendan might improve survival when adequate end-organ perfusion is ensured by concomitant ECMO therapy. We therefore studied the impact of levosimendan treatment on survival and failure of ECMO weaning in patients after cardiovascular surgery. Methods We enrolled a total of 240 patients undergoing veno-arterial ECMO therapy after cardiovascular surgery at a university-affiliated tertiary care centre into our observational single-centre registry. Results During a median follow-up period of 37 months (interquartile range 19–67 months), 65% of patients died. Seventy-five per cent of patients received levosimendan treatment within the first 24 h after initiation of ECMO therapy. Cox regression analysis showed an association between levosimendan treatment and successful ECMO weaning [adjusted hazard ratio (HR) 0.41; 95% confience interval (CI) 0.22–0.80; P=0.008], 30 day mortality (adjusted HR 0.52; 95% CI 0.30–0.89; P=0.016), and long-term mortality (adjusted HR 0.64; 95% CI 0.42–0.98; P=0.04). Conclusions These data suggest an association between levosimendan treatment and improved short- and long-term survival in patients undergoing ECMO support after cardiovascular surgery.

    Pre-operative hypotensive drugs are assumed to have dramatically decreased operative mortality and morbidity in patients undergoing phaeochromocytoma removal only in non-controlled studies. We evaluated the predictive value of pre-operative high systolic arterial pressure (SAP) on intra- and post-operative haemodynamic instability, in 96 patients undergoing laparoscopic adrenalectomy for phaeochromocytoma. Ninety-six consecutive patients underwent laparoscopic adrenalectomy for phaeochromocytoma. Pre-operative SAP was not systematically normalised, provided that increased SAP was clinically tolerated. Intravenous nicardipine, esmolol and norepinephrine were intraoperatively titrated to treat SAP increase >150 mmHg, tachycardia >90-110/min, arrhythmia or SAP decrease under 90 mmHg, respectively. Volume expanders were not systematically administered. Patients with increased and normal pre-operative SAP were compared with respect to (a) nicardipine, esmolol and norepinephrine requirement, (b) highest intraoperative SAP and heat rate, (c) lowest intraoperative SAP, (d) duration of surgery and (e) norepinephrine requirement following tumour removal. Groups did not differ significantly with respect to data defined as being indicative of perioperative haemodynamic instability (all P values>0.05). As previously demonstrated, in patients undergoing phaeochromocytoma removal, perioperative haemodynamic changes are mainly due to catecholamine release during tumour manipulation, and to the decrease in catecholamine level following tumour removal. Whether pre-operative hypotensive drugs are likely to alter these changes remains questionable. For most patients scheduled for laparoscopic phaeochromocytoma removal, surgery can be carried out without systematic pre-operative arterial pressure normalisation.

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

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

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

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

    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.

    Objective. Patients with diabetic foot ulcers undergoing amputations have poor prognosis. Malnutrition usually occurs in this population and is associated with increased risk of mortality. The geriatric nutritional risk index (GNRI) is a widely used, simple, and well-established tool to assess nutritional risk. The purpose of this study was to assess the association between GNRI and all-cause mortality in diabetic foot ulcers patients undergoing minor or major amputations. Methods. This was a retrospective cohort study including 271 adult patients. Patients were divided into two groups according to a GNRI cutoff value of 92, and characteristics and mortality were compared between the two groups. Cox proportional hazard analysis was performed to explore the association between GNRI and mortality. Result. GNRI (p < 0.001), age (p < 0.001), and eGFR (p = 0.002) were independent predictors of mortality. Among a subgroup of 230 patients with minor amputation, increased age (p < 0.001), coronary artery disease (p = 0.030), and increased GNRI (p < 0.001) were major risk factors. Conclusion. GNRI on admission might be a novel clinical predictor for the incidence of death in patients with diabetic foot ulcers who were undergoing amputations. PMID:28164133

    The number of cancer patients undergoing dialysis has been increasing, and the number of these patients on chemotherapy is also increasing. Imatinib is an effective and safe therapy for KIT-positive gastrointestinal stromal tumors (GIST), but the efficacy and safety of imatinib in dialysis patients remain unclear. Because clinical trials have not been conducted in this population, more investigations are required. We report on a 75-year-old Japanese man undergoing dialysis who presented with massive tarry stool from a duodenal GIST. The duodenal GIST was 14 cm in diameter with multiple liver and bone metastases. The patient underwent an urgent pancreaticoduodenectomy to achieve hemostasis. After surgery, he was administered imatinib 400 mg/day. No severe adverse event including myelosuppression, congestive heart failure, liver functional impairment, intestinal pneumonia, or Steven-Johnson syndrome occurred, and the liver metastasis remained stable for 4 months. During chemotherapy, hemodialysis continued three times per week without adverse events. We suggest that regular-dose imatinib is an effective and safe treatment in patients with GIST undergoing dialysis. In addition, we present a literature review of the effectiveness and safety of imatinib treatment in dialysis patients.

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

    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.

    To report on a 39-year-old gentleman with a background of Type 2 diabetes mellitus who was diagnosed with acute promyelocytic leukemia (APL), which was treated by all-trans retinoic acid (ATRA), and subsequently developed bilateral neovascularization of the disk (NVD). Ophthalmic examination and investigation including fundus photography and fluorescein angiography. Three months after commencement of ATRA therapy, the patient was found to have florid bilateral NVD with adjacent preretinal and intraretinal hemorrhages. Fundus fluorescein angiography was undertaken and NVD was confirmed in both eyes, which was significantly greater than expected for the extent of disease secondary to diabetic retinopathy. As a result of the fluorescein angiography findings, we believe ATRA-mediated upregulation of vascular endothelial growth factor may be the etiology of the NVD. Literature review shows some in vitro studies, which describe ATRA-induced upregulation of vascular endothelial growth factor in ocular tissues. The patient was managed successfully by cessation of ATRA and a single intravitreal injection of bevacizumab in each eye. Acute promyelocytic leukemia treated with ATRA may result in upregulation of vascular endothelial growth factor in retinal tissues. Subsequent development of NVD may occur; however, this resolves well by cessation of ATRA and intravitreal injection of bevacizumab. We recommend that all patients undergoing treatment with ATRA for acute promyelocytic leukemia be monitored by an ophthalmologist.

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

    The hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile international normalized ratio, elderly, and drugs/alcohol (HAS-BLED); anticoagulation and risk factors in atrial fibrillation (ATRIA); modified Outpatient Bleeding Risk Index (mOBRI); and reduction of atherothrombosis for continued health (REACH) schemes are validated bleeding risk-prediction tools, but their predictive performance in patients with AF receiving multiple antithrombotic drugs after percutaneous coronary intervention (PCI) is unknown. We sought to compare the predictive performance of bleeding risk-estimation tools in a cohort of patients with atrial fibrillation (AF) undergoing PCI. Management of patients with AF undergoing coronary artery stenting is a multicenter European prospective registry enrolling patients with AF undergoing PCI. We calculated HAS-BLED, ATRIA, mOBRI, and REACH bleeding risk-prediction scores and assessed the rate of bleeding complications as defined by Bleeding Academic Research Consortium at 12 months follow-up in 929 consecutive patients undergoing PCI. Increasing age, femoral access site, and previous peptic ulcer were independent determinants of bleeding. Low bleeding risk scores as determined by HAS-BLED 0 to 2, ATRIA 0 to 3, mOBRI 0, and REACH 0 to 10 were detected in 23.7%, 73.0%, 7.8%, and 5.7% of patients of the cohort, respectively. No significant differences were detected in the rates of any bleeding or major bleeding events for low versus intermediate/high scores with each risk-prediction tool. In conclusion, the performance of ATRIA, HAS-BLED, mOBRI, and REACH scores in predicting bleeding complications in this high-risk patient subset was useless.

    Background Postoperative nausea and vomiting (PONV) are commonly feared after general anesthesia and can impact results. The primary aim of our study was to examine incidence and severity of PONV by investigating complete response, or absence of PONV, to prophylaxis used in patients undergoing DIEP flaps. Our secondary aims were definition of the magnitude of risk, state of the art of interventions, clinical sequelae of PONV, and interaction between these variables, specifically for DIEP patients. Methods A retrospective chart review occurred for 29 patients undergoing DIEP flap breast reconstruction from September 2007 to February 2008. We assessed known patient and procedure-specific risks for PONV after DIEPs, prophylactic antiemetic regimens, incidence, and severity of PONV, postoperative antiemetic rescues, and effects of risks and treatments on symptoms. Results Three or more established risks existed in all patients, with up to seven risks per patient. Although 90% of patients received diverse prophylaxis, 76% of patients experienced PONV, and 66% experienced its severe form, emesis. Early PONV (73%) was frequent; symptoms were long lasting (average 20 hours for nausea and emesis); and multiple rescue medications were frequently required (55% for nausea, 58% for emesis). Length of surgery and nonsmoking statistically significantly impacted PONV. Conclusion We identify previously undocumented high risks for PONV in DIEP patients. High frequency, severity, and refractoriness of PONV occur despite standard prophylaxis. Plastic surgeons and anesthesiologists should further investigate methods to optimize PONV prophylaxis and treatment in DIEP flap patients. PMID:24038427

    Undernutrition is common in surgical patients, is frequently unrecognised and is strongly associated with adverse outcomes such as high rates of complications and mortality, worsening functional status and prolonged hospitalisation. Owing to the associated infection and symptoms such as repeated vomiting, a high prevalence of undernutrition is expected in hydrocephalus patients, which may contribute to their poor surgical outcomes. The aim of this study was to evaluate the influence of preoperative nutritional status on the outcome of Indian patients with hydrocephalus undergoing neurosurgical shunt surgery. One hundred and twenty-four consecutive patients undergoing scheduled hydrocephalus shunt surgery were studied prospectively. All patients underwent nutritional screening according to different parameters prior to surgery. The patients were classified into normally nourished and undernourished groups. The undernourished group was further subdivided into moderately and severely undernourished. The surgical outcome was compared between these groups. A high prevalence (53%) of undernutrition was observed in these patients. Postoperative complications such as shunt infection (P = 0.0023), shunt revision (P = 0.0074) and mortality (P = 0.0003) were significantly more common in undernourished patients compared with normally nourished patients. Serum albumin emerged as the most significant independent predictor of postoperative mortality. The present study demonstrated a high prevalence of undernutrition in hydrocephalus patients in India and its adverse influence on the outcome of shunt surgery. Early preoperative nutritional status screening and its optimisation may decrease the morbidity and mortality of shunt surgery for hydrocephalus.

    Background: Fatigue is a common symptom referred by many patients undergoing hemodialysis. Fatigue is associated with poor health-related quality of life (HRQoL) and is an important predictor for survival of hemodialysis patients. Aim: To assess the levels of fatigue and demographic factors affecting it among patients with End Stage Renal Disease undergoing hemodialysis. Methods: This quantitative study was carried out in two Dialysis Units of Hospitals in Athens Region. Between January 2015 and June 2015, 129 hemodialysis patients completed the Greek Version of the Fatigue Assessment Scale (FAS). Demographic data of patients was recorded. For the statistical analysis IBM SPSS Statistics version 20 was used. Results: The mean FAS score was 24.99. 49 patients (38.0%) were non fatigued, 61 patients (47.3%) were fatigued, and 19 patients (13.7%) were extremely fatigued. Higher levels of fatigue were reported among hemodialysis patients residing in urban areas, in those with low educational level and unemployed. Conclusion: The findings of this study can be used in the assessment of fatigue and early identification of high-risk patients (especially of the unemployed, those who occupy with domestic works, those with low educational level and of urban citizens). Use of this knowledge by hemodialysis nurses may lead to a better understanding of the factors of fatigue in ESRD, which in turn may lead to a more effective treatment. PMID:26843728

    Acute coronary syndrome (ACS) represents the most common cause of death worldwide. Percutaneous coronary intervention (PCI) is the management of choice in patients with ACS and occurrence of intra-procedural thrombotic complications are an independent predictor of mortality and other major adverse cardiovascular events in patients undergoing PCI. According to current guideline, anticoagulation therapy is indicated during PCI in order to reduce the risk of thrombotic complications such as stent thrombosis. Among currently available anticoagulant drugs, bivalirudin demonstrates a lower incidence of bleeding risk, despite it is associated with an increased risk of stent thrombosis. The aim of this paper is to discuss the pharmacology of bivalirudin and the clinical evidences of its use in patients undergoing PCI for ACS. PMID:27326396

    To explore the effects of the prevention and control of perioperative incision infection on the quality of day cataract surgery. The nursing care and efficacy of 5087 patients undergoing day cataract surgery between October 2012 and October 2013 were retrospectively reviewed. The disinfection and isolation guidance was established for perioperative prevention and control of infection, topical administration of ocular agents, reexamination and healthcare instruction, and alternative measures were taken. All 5087 patients successfully underwent day surgery of phacoemulsification combined with intraocular lens implantation. All cases recovered without incision infection. Preoperative preparation, and intraoperative and postoperative prevention and control of infection serve as vital measures for effectively avoiding the incidence of incision infection in patients undergoing day cataract surgery.

    The saliva of patients undergoing orthodontic treatment with fixed appliances can potentially present a delay in the diluting, clearing, and buffering of dietary acids due to an increased number of retention areas. The aim of this clinical trial was to compare salivary pH kinetics of patients with and without orthodontic treatment, following the intake of an acidic beverage. Twenty participants undergoing orthodontic treatment and 20 control counterparts had their saliva assessed for flow rate, pH, and buffering capacity. There was no significant difference between salivary parameters in participants with or without an orthodontic appliance. Salivary pH recovery following acidic beverage intake was slower in the orthodontic subjects compared to controls. Patients with fixed orthodontic appliances, therefore, seem to be at higher risk of dental erosion, suggesting that dietary advice and preventive care need to be implemented during orthodontic treatment.

    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.

    Coronary artery disease (CAD) is common in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI), but its clinical relevance is controversial. At present, the optimal means of defining CAD in patients undergoing TAVI with respect to its prognostic implications and the assessment of myocardial ischaemia is not known. For this reason, the best treatment options are a matter for debate, and current guidelines do not recommend revascularization. As the indications for TAVI expand, the lack of any rigorous means of guiding coronary revascularization might negatively affect the clinical outcomes of future patients. In this Review, we summarize the methods of assessing CAD in TAVI populations, and the data on the safety and efficacy of percutaneous coronary intervention in patients undergoing TAVI. We discuss the putative effects of aortic stenosis on the functional assessment of CAD using pressure or flow wires or by noninvasive stress testing. We propose that a new, well-validated method of assessing CAD as a cause of myocardial ischaemia--which distinguishes it from myocardial infarction, previous revascularization, or non-flow-limiting disease--in patients with severe aortic stenosis is needed to guide revascularization in the current era of TAVI.

    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.

    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.

    Dual antiplatelet therapy is commonly used in patients undergoing transcatheter aortic valve implantation (TAVI), but the optimal antiplatelet regimen is uncertain and remains to be determined. The objective of this study was to compare 2 strategies of antiplatelet therapy in patients undergoing TAVI. A strategy using monoantiplatelet therapy (group A, n = 164) was prospectively compared with a strategy using dual antiplatelet therapy (group B, n = 128) in 292 consecutive patients undergoing TAVI. The primary end point was a combination of mortality, major stroke, life-threatening bleeding (LTB), myocardial infarction, and major vascular complications at 30 days. All adverse events were adjudicated according to the Valve Academic Research Consortium. The primary end point occurred in 22 patients (13.4%) in the group A and in 30 patients (23.4%) in the group B (hazard ratio 0.51, 95% confidence interval 0.28 to 0.94, p = 0.026). LTB (3.7% vs 12.5%, p = 0.005) and major bleedings (2.4% vs 13.3%, p <0.0001) occurred less frequently in the group A, whereas the incidence of stroke (1.2% vs 4.7%, p = 0.14) and myocardial infarction (1.2% vs 0.8%, p = 1.0) was not significantly different between the 2 groups. The benefit of a strategy using mono versus dual antiplatelet therapy persisted after multivariate adjustment and propensity score analysis (hazard ratio 0.53, 95% confidence interval 0.28 to 0.95, p = 0.033). In conclusion, a strategy using mono versus dual antiplatelet therapy in patients undergoing TAVI reduces LTB and major bleedings without increasing the risk of stroke and myocardial infarction. The results of our study question the justification of dual antiplatelet therapy and require confirmation in a randomized trial. Copyright © 2014 Elsevier Inc. All rights reserved.

    Advances in bariatric surgery have brought about a paradigm shift in the management of obesity, with benefits extending beyond weight loss. However, nutritional deficiencies are an inherent problem in the postoperative period and often require lifelong supplementation. Vitamin B12, also referred to as cobalamin, is one of the most common micronutrient deficiencies affecting this population. This review explores the pathophysiology of cobalamin deficiency in patients undergoing bariatric surgery and provides an overview of the effectiveness of various available vitamin B12 formulations. To identify the relevant literature, a systematic review of MEDLINE was conducted from the earliest dates through September 2012 for English-language articles describing the prevention and management of vitamin B12 deficiency in patients undergoing bariatric surgery. Intramuscular vitamin B12 continues to be the gold standard of therapy for vitamin B12 deficiency, especially in symptomatic patients. In select patients with asymptomatic vitamin B12 deficiency after Roux-en-Y gastric bypass (RYGB), high-dose oral cyanocobalamin should be given a consideration, especially when there are concerns with the adherence to intramuscular therapy or if compliance comes into question. Unlike patients post-RYGB, those undergoing restrictive procedures such as gastric banding and sleeve gastrectomy may be maintained postoperatively on a lower-dose daily vitamin B12 supplementation. Efficacy data of nasal and sublingual routes for maintenance therapy is currently awaited. Patients undergoing bariatric surgery must be continuously educated on proper nutrition, the risk of developing significant vitamin B12 deficiency, and the role of supplements in avoiding catastrophic consequences.

    Because informed consent requires discussion of alternative treatments, proper consent for dialysis should incorporate discussion about other renal replacement options including kidney transplantation (KT). Accordingly, dialysis providers are required to indicate KT provision of information (KTPI) on CMS Form-2728; however, provider-reported KTPI does not necessarily imply adequate provision of information. Furthermore, the effect of KTPI on pursuit of KT remains unclear. We compared provider-reported KTPI (Form-2728) with patient-reported KTPI (in-person survey of whether a nephrologist or dialysis staff had discussed KT) in a prospective ancillary study of 388 hemodialysis initiates. KTPI was reported by both patient and provider for 56.2% of participants, by provider only for 27.8%, by patient only for 8.3%, and by neither for 7.7%. Among participants with provider-reported KTPI, older age was associated with lack of patient-reported KTPI. Linkage with the Scientific Registry for Transplant Recipients showed that 20.9% of participants were subsequently listed for KT. Patient-reported KTPI was independently associated with a 2.95-fold (95% confidence interval [95% CI], 1.54 to 5.66; P=0.001) higher likelihood of KT listing, whereas provider-reported KTPI was not associated with listing (hazard ratio, 1.18; 95% CI, 0.60 to 2.32; P=0.62). Our findings suggest that patient perception of KTPI is more important for KT listing than provider-reported KTPI. Patient-reported and provider-reported KTPI should be collected for quality assessment in dialysis centers because factors associated with discordance between these metrics might inform interventions to improve this process.

    Symptom validity tests (SVTs) are commonly used to assess effort in neuropsychological evaluations. However, no empirical research or official guidelines exist about how clinicians should proceed if a patient produces a non-valid SVT result. The purpose of this study was to examine whether confronting patients immediately after scoring in a non-valid range on a SVT would have an impact on subsequent symptom validity and memory tests performance. Archival patient data for 507 adults with clinically definite multiple sclerosis (MS) (ages 18-76) were examined. All patients completed the Victoria Symptom Validity Test (VSVT), the Wechsler Memory Scale, 3rd edition (WMS III), and the Beck Depression Inventory, 2nd edition (BDI II). Although the majority (89%) of patients produced valid VSVT scores (the Valid group), 56 patients produced non-valid VSVT scores. Due to a change in clinical procedure, 28 of the 56 were confronted regarding their non-valid VSVT performances and were asked to complete the test a second time (the CONF group), while the remaining 28 proceeded with testing as usual following a non-valid score (the N-CONF group). Results showed that 68% of the CONF group produced valid VSVT scores on re-administration, as well as memory performances that were comparable to those of the Valid group. In contrast the N-CONF group produced memory scores that were significantly below the Valid group. This is the first study to provide empirical support for the effectiveness of intervention when patients exhibit inadequate effort on SVTs in clinical, non-forensic settings.

Although they were generally satisfied with the quality of information they received at their outpatient consultation and at the preadmission clinic, they were less satisfied with the quality of information provided by their GPs and by the quality of self - obtained information. Most importantly, linear regression modeling showed that the overall level of information could be predicted by three factors: The quality of written information received at the hospital, the quality of self-obtained information and the information provided by the specialist at the time of listing for surgery. While patient's education level was correlated with the information process, the age and gender of the patient as well as the grade of the doctor at the outpatients were not associated with his overall levels of satisfaction. Although the impact of the initial outpatient consultation for patients undergoing elective surgery can not be over emphasized, written information provided at the hospital as well as patient - initiated, parallel information pathways are at least as important: It is our duty to recognize them and use them for the patient's advantage.

    Background and purpose - Recent evidence has questioned the effect of arthroscopic knee surgery for middle-aged and older patients with degenerative meniscal tears with or without concomitant radiographic knee osteoarthritis (OA). We investigated the prevalence of early or more established knee OA and patients' characteristics in a cohort of patients undergoing arthroscopic surgery for a meniscal tear. Patients and methods - 641 patients assigned for arthroscopy on suspicion of meniscus tear were consecutively recruited from February 2013 through January 2015. Of these, 620 patients (mean age 49 (18-77) years, 57% men) with full datasets available were included in the present study. Prior to surgery, patients completed questionnaires regarding onset of symptoms, duration of symptoms, and mechanical symptoms along with the knee injury and osteoarthritis outcome score (KOOS). At arthroscopy, the operating surgeon recorded information about meniscal pathology and cartilage damage. Early or more established knee OA was defined as the combination of self-reported frequent knee pain, cartilage damage, and the presence of degenerative meniscal tissue. Results - 43% of patients (269 of 620) had early or more established knee OA. Of these, a large proportion had severe cartilage lesions with almost half having a severe cartilage lesion in at least 1 knee compartment. Interpretation - Based on a definition including frequent knee pain, cartilage damage, and degenerative meniscal tissue, early or more established knee OA was present in 43% of patients undergoing knee arthroscopy for meniscal tear.

    Can we identify modifiable risk factors for peritonitis in patients undergoing peritoneal dialysis (PD)? We aimed to determine whether housing standard, PD exchange technique or patient motivation might be modifiable risks for peritonitis. We also explored the relationship between lack of motivation and depression. Nurse home visits assessed PD exchange technique, environment and patient motivation. Motivation scores were correlated separately with an Apathy Evaluation Score and a depression score using PHQ-9 questionnaires. Home hygiene, exchange technique and motivation were above average in 53%, 56% and 60%, respectively in 104 patients undergoing PD. After 15 months, 25.9% patients developed peritonitis but nurses' ratings of homes and exchange techniques were not predictive. Low patient motivation was predictive. Patients rated to have above or below median motivation had significantly different Apathy Scores (p = 0.0002). Unmotivated depressed patients were significantly more likely to develop peritonitis compared to motivated depressed patients. Lack of motivation predicted peritonitis particularly if associated with depression. Further studies are required focusing on specific motivation scoring schemes and the psychosocial support that might lead to better outcomes. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    The introduction of the hospitalist co-management model represents an opportunity to improve care by changing the system as it applies to a small group of patients. Eighty-six consecutive patients with multiple comorbidities were selectively enrolled in an academic medical center hospitalist-orthopedic surgery co-management patient care program. Patients were stratified by all patient refined diagnosis-related groups, severity of illness, and risk of mortality. Hospital length of stay, cost of care, in-hospital mortality, complications, and intensive care unit admissions were compared with a retrospectively constructed control group of 54 patients undergoing similar surgery during the period immediately preceding initiation of the program. The University Health System Consortium observed-to-expected ratio for hospital length of stay was 0.693 compared to 0.862 for the control group. The severity of illness and risk of mortality scores represented a relatively higher risk stratification in the study group. While the overall observed-to-expected cost of care remained virtually unchanged, the positive impact of the study model revealed an increased positive effect on the more severely affected severity of illness and risk of mortality patients. The results of this study suggest that a proactive, cooperative, co-management model for the perioperative management of high-risk patients undergoing complex surgery can improve the quality and efficiency metrics associated with the delivery of service to patients.

    To analyse the impact of preoperative defecation pattern on postoperative defecation pattern for patients undergoing cardiac surgery. Constipation is a neglected problem that occurs frequently after cardiac surgery. Descriptive study. The study sample comprised 102 patients who underwent cardiac surgery. A Descriptive Information Form, Rome III Diagnostic Criteria, Constipation Severity Instrument, Postoperative Defecation Pattern Evaluation Form and Bristol Stool Form Scale were used for data collection and analysis. The Constipation Severity Instrument scores of just over one-third (37·2%) of the patients who were constipated prior to surgery were higher compared to those who were not constipated. Following cardiac surgery, 39·2% of patients developed constipation and 80% of these patients were constipated prior to cardiac surgery. The findings indicate a significantly high relationship between preoperative and postoperative defecation pattern (r = 0·71, p < 0·001). Preoperative defecation pattern is a determining factor for the development of postoperative constipation for patients undergoing cardiac surgery. During the preoperative period, clinical nurses may evaluate the patients' defecation patterns using valid and reliable scales and follow the defecation of the patients, especially patients with defecation problems, during the postoperative period. © 2016 John Wiley & Sons Ltd.

    The presence of nerve fibres in the functional layer of the endometrium has been strongly associated with endometriosis. Presence of nerve fibres in the endometrium of women undergoing IVF has not been previously assessed. This prospective pilot study assessed the presence of nerve fibres in endometrium of women undergoing IVF due to various causes and examined the correlation between the presence of nerve fibres and IVF success. A total of 32 IVF patients underwent endometrial biopsy during days 21-23 of the menstrual cycle. Nerve fibres were identified by immunohistochemical staining. Correlations between the presence and density of nerve fibres and aetiology of infertility and IVF success were measured. Nerve fibres were identified in the endometrium of 10/31 (32.3%) women with a satisfactory biopsy. Presence of nerve fibres was not correlated with cause of infertility. Clinical pregnancy was achieved in 12/32 (37.5%) patients, without correlation to presence of nerve fibres in the endometrium. Nerve fibres were identified in a substantial percentage of women undergoing IVF, possibly reflecting underdiagnosis of endometriosis in this population. The presence of nerve fibres does not appear to interfere with implantation. The significance of nerve fibres in the endometrium of IVF patients warrants further research.

    Patients with acute venous thromboembolism (VTE) are at increased risk for the development of subsequent arterial ischemic events unrelated to the diagnosis of VTE. Accurate identification of VTE patients at increased risk for ischemic events during the course of anticoagulation may help to select those who would potentially benefit from concomitant therapy with anticoagulants and antiplatelets. We used the Registro Informatizado de Enfermedad TromboEmbólica (RIETE) Registry to assess the rate and severity of subsequent ischemic events (ie, stroke, myocardial infarction, lower limb amputation, or mesenteric ischemia) appearing during the course of anticoagulant therapy and tried to identify risk factors for these events. From February 2009 to March 2014, 23,370 patients were recruited: 12,397 initially presenting with pulmonary embolism (PE) and 10,973 with deep venous thrombosis. During the course of anticoagulation (mean, 9.2 months), 597 patients developed recurrent VTE, 652 bled, 162 had ischemic events (stroke, 86; myocardial infarction, 53; limb amputation, 13; mesenteric ischemia, 11), and 2063 died. Of these, 29 patients died of recurrent PE, 83 of bleeding, and 53 of the ischemic events. On multivariable analysis, cancer (hazard ratio [HR], 1.77; 95% confidence interval [CI], 1.21-2.61), chronic lung disease (HR, 1.54; 95% CI, 1.05-2.26), renal insufficiency (HR, 1.72; 95% CI, 1.25-2.36), anemia (HR, 1.54; 95% CI, 1.11-2.14), prior artery disease (HR, 1.84; 95% CI, 1.29-2.64), and diabetes (HR, 1.58; 95% CI, 1.10-2.27) independently predicted the risk for ischemic events. Most of these variables also predicted major bleeding (cancer, chronic lung disease, renal insufficiency, anemia, and prior artery disease) or recurrent PE (cancer, chronic lung disease, anemia, and prior artery disease). In patients receiving anticoagulation for VTE, the mortality due to PE recurrences was lower than the mortality due to ischemic events. Most independent predictors for

    Background: Sleep is one of the most fundamental human needs; without any doubt sleep is even more essential for sick patients, especially for patients with chronic illnesses. Sleep disturbance may lead to anxiety and reduced quality of life. Restless leg syndrome (RLS) is a sensory-motor disorder accompanied by a strong desire to move the legs or other parts of the body, which can cause sleep disturbance. Its etiology is unknown, but increased urea and creatinine levels before dialysis, iron deficiency due to kidney failure and end-stage renal disease (ESRD) are mentioned as causes. Objectives: This study is designed to examine the prevalence of insomnia and restless leg syndrome in patients undergoing chronic hemodialysis in Rafsanjan Ali Ibn Abitaleb Hospital. Patients and Methods: In this study we used two questionnaires to evaluate the presence of RLS and insomnia in ESRD patients who were undergoing hemodialysis treatment as kidney replacement therapy. Results: According to our results, 54.5% of patients were diagnosed with RLS, and of those 65.2% and 42.9% were women and men, respectively. RLS is seen more often among patients with blood group type A, but this result was not statistically significant. There was a statistically significant correlation between RLS and a positive family history of RLS, between RLS and the number of hemodialysis treatments per week and also between RLS and the Insomnia Severity Index. Unlike previous studies, in this study we did not find any statistically significant correlation between RLS and biochemical factors such as serum iron, TIBC, BUN, creatinine, potassium, calcium and phosphorous levels. Conclusions: The frequency of RLS among our patients was remarkable and we conclude that all patients who are undergoing hemodialysis should be screened for RLS, which can assist in providing proper attention and treatment.

    Successful CTO recanalization has been associated with clinical benefit. Outcomes of patients with atrial fibrillation undergoing CTO PCI have not been investigated, yet. This study sought to evaluate the association between atrial fibrillation and outcomes after percutaneous coronary intervention (PCI) for chronic total occlusions (CTO). Consecutive patients undergoing CTO PCI between January 2005 and December 2013 were divided into patients with and without atrial fibrillation, and propensity-matched models used to adjust for baseline differences between groups. The primary outcome was all-cause mortality at a median follow-up of 3.2 (interquartile range 3.1-4.5) years. Of 2002 patients undergoing CTO PCI, atrial fibrillation was present in 169 (8.4%) patients. Patients with atrial fibrillation were older, and more frequently had hypertension, left ventricular systolic dysfunction, and chronic kidney disease. Before matching, all-cause mortality was 39.6 and 14.5% in the atrial fibrillation and the sinus rhythm groups (HR 2.92, 95% CI 2.23-3.82, p < 0.001). In the propensity-matched model, atrial fibrillation remained associated with an increased risk of mortality (HR 1.62, 95% CI 1.06-2.47, p = 0.03). In the unmatched patient cohort, all-cause mortality was significantly reduced in patients with procedural success, both in the atrial fibrillation (34.9 versus 55.0%, adjusted HR 0.99, 95% CI 0.97-1.00, p = 0.02) and the sinus rhythm groups (12.8 versus 23.0%, adjusted HR 0.70, 95% CI 0.53-0.92, p = 0.01). Although atrial fibrillation is independently associated with mortality after CTO PCI, substantial survival benefit of successful CTO recanalization is observed in both patients with and without atrial fibrillation.

    Background Current methods to predict patients' peri-operative morbidity utilize complex algorithms with multiple clinical variables focusing primarily on organ-specific compromise. The aim of the present study is to determine the value of a timed stair climb (SC) in predicting peri-operative complications for patients undergoing abdominal surgery. Study Design From March 2014 to July 2015, 362 patients attempted SC while being timed prior to undergoing elective abdominal surgery. Vital signs were measured before and after SC. Ninety day post-operative complications were assessed by the Accordion Severity Grading System. The prognostic value of SC was compared to the ACS NSQIP risk calculator. Results A total of 264 (97.4%) patients were able to complete SC. SC time directly correlated to changes in both mean arterial pressure and heart rate as an indicator of stress. An Accordion grade 2 or higher complication occurred in 84 (25%) patients. There were 8 mortalities (2.4%). Patients with slower SC times had an increased complication rate (P<0.0001). In multivariable analysis SC time was the single strongest predictor of complications (OR=1.029, P<0.0001), and no other clinical co-morbidity reached statistical significance. Receiver operative characteristic curves predicting post-operative morbidity by SC time was superior to that of the ACS risk calculator (AUC 0.81 vs. 0.62, P<0.0001). Additionally slower patients had a greater deviation from predicted length of hospital stay (P=0.034) Conclusions SC provides measurable stress, accurately predicts post-operative complications, and is easy to administer in patients undergoing abdominal surgery. Larger patient populations with a diverse group of operations will be needed to further validate the use of SC in risk prediction models. PMID:26920993

    Background and study aims: Colonoscopy can cause anxiety and discomfort in patients. Sedation and analgesia as premedication can lead to complications in the elderly and those with comorbidities. This has led to an interest in the use of audio-visual distraction during the colonoscopy. We compared the effects of audio (AD) versus visual distraction (VD) in reducing discomfort and the need for sedation during colonoscopy. Patients and methods: Consecutive patients undergoing colonoscopy were randomized into three groups: one group was allowed to listen to the music of their choice (AD), the second group was allowed to watch a movie of their choice (VD), and the third group was not allowed either distraction during colonoscopy and acted as a control (C). Patient controlled analgesia and sedation were administered to all three groups. We used 25 mg of pethidine in 5-mg aliquots and 2.5 mg of midazolam in 0.5-mg aliquots. All patients were assessed for perceived pain and willingness to repeat the procedure. Number of “top-ups” of sedation and total dose of pethidine and midazolam were noted. Patient cooperation and ease of procedure were assessed by the colonoscopist. Results: In total, 200 patients were recruited [AD, n = 66 (32 males, median age 57 years); VD, n = 67 (43 males, median age 58 years); C, n = 67 (35 males, median age 59 years)]. The AD group had significantly less pain (P = 0.001), better patient cooperation (P = 0.001) and willingness to undergo a repeat procedure (P = 0.024) compared with VD and C groups. Conclusions: AD reduces pain and discomfort, improves patient cooperation and willingness to undergo a repeat procedure, and seems a useful, simple adjunct to low dose sedation during colonoscopy.

    BACKGROUND Recent literature suggests that lipid-lowering therapy may have an early beneficial effect among patients undergoing percutaneous coronary intervention (PCI) because the therapy decreases cardiac mortality, morbidity and possibly restenosis. OBJECTIVE The primary objective of the present study was to determine the proportion of PCI patients receiving lipid-lowering therapy at a large, tertiary-care referral centre. METHODS Patients undergoing a first PCI between August 2000 and August 2002 with corresponding inpatient medication information were included in the study. Patient demographics, procedural variables, and lipid-lowering and other evidence-based cardiac medication data were collected. A multiple logistical regression model was constructed to evaluate the factors associated with the use of lipid-lowering therapy. RESULTS Of the 3254 cases included in the analyses, 52% were elective, 44% were urgent or salvage, and 4% were emergent. The mean patient age was 63 years, and 73% of patients were male. Over 76% of patients were receiving lipid-lowering therapy at the time of PCI. Patient use of other medications was as follows: acetylsalicylic acid in 96%, beta-blocker in 80% and angiotensin-converting enzyme inhibitor in 59%. In the multiple regression analysis, variables significantly associated with lipid-lowering therapy use included hypercholesterolemia, beta-blocker use, angiotensin-converting enzyme inhibitor use, case urgency, prior coronary artery bypass graft surgery, age and sex. CONCLUSION Lipid-lowering therapy use rates exceeded those previously reported in the literature. Women and patients undergoing elective procedures appear to be treated less often with lipid-lowering therapy. There remains an opportunity to further optimize use in this high-risk cohort at time of PCI. PMID:16639478

    The study aim was to examine the impact of concomitant significant mitral regurgitation (MR) in patients undergoing transcatheter aortic valve implantation (TAVI). TAVI has become an acceptable mode of treatment for high-surgical risk patients with aortic stenosis (AS) requiring valve replacement. A significant number of patients have concomitant MR which cannot be addressed by TAVI alone, and therefore may not be considered candidates for this procedure. A comparison was conducted of results obtained from patients undergoing TAVI with or without MR. Between 2008 and 2013, a total of 164 patients (mean age 81 ± 8 years) underwent TAVI at the authors' institution. Of these patients, 87 (53%) had MR of moderate or greater degree. The groups were similar with respect to age, gender, presence of congestive heart failure, left ventricular function and co-morbid conditions. The logistic EuroSCORE was higher in the MR group (p = 0.02). Procedural (30-day) mortality was 12% (n = 19) and similar between groups. Kaplan-Meier estimates showed the overall survival at three years to be 68% and 76% for the MR and non-MR groups, respectively (p = 0.6). By Cox regression, age (p = 0.007) and peripheral vascular disease (p = 0.03) were the only predictors of late survival. Regression of MR was seen in patients with functional MR. Neither the presence of MR nor residual MR emerged as predictors of late mortality. In elderly patients undergoing TAVI the presence of MR does not impact survival. TAVI should not be withheld from this group of patients because of concomitant MR.

    Left ventricular hypertrophy (LVH) is exceedingly frequent in patients undergoing dialysis. Cardiac mass is proportional to body size, but the influence of various indexing methods has not been studied in patients with end-stage renal disease. The issue is important because malnutrition and volume expansion would both tend to distort the estimate of LV mass (LVM) in these patients. In a cohort of 254 patients, the prognostic impact on all-cause mortality and cardiovascular outcomes of LVH values, calculated according to two established methods of indexing, either body surface area (BSA) or height(2.7), was assessed prospectively. When LVM was analyzed as a categorical variable, the height(2.7)-based method identified a larger number of patients with LVH than the corresponding BSA-based method. One hundred and thirty-seven fatal and nonfatal cardiovascular events occurred during the follow-up period. Overall, 90 patients died, 51 of cardiovascular causes. In separate Cox models, both the LVM/height(2.7) and the LVM/BSA index independently predicted total and cardiovascular mortality (P < 0.001). However, the height(2.7)-based method coherently produced a closer-fitting model (P < or = 0.02) than did the BSA-based method. The height(2.7) index was also important for the subcategorization of patients according to the presence of concentric or eccentric LVH because the prognostic value of such subcategorization was apparent only when the height(2.7)-based criterion was applied. In conclusion, LVM is a strong and independent predictor of survival and cardiovascular events in patients undergoing dialysis. The indexing of LVM by height(2.7) provides more powerful prediction of mortality and cardiovascular outcomes than the BSA-based method, and the use of this index appears to be appropriate in patients undergoing dialysis.

    Bariatric surgery is the most effective treatment for obesity. However, not all patients have similar weight loss following surgery and many researchers have attributed this to different pre-operative psychological, eating behavior, or quality-of-life factors. The aim of this study was to determine whether there are any differences in these factors between patients electing to have bariatric surgery compared to less invasive non-surgical weight loss treatments, between patients choosing a particular bariatric surgery procedure, and to identify whether these factors predict weight loss after bariatric surgery. This was a prospective study of 90 patients undergoing gastric bypass, vertical sleeve gastrectomy, or adjustable gastric banding and 36 patients undergoing pharmacotherapy or lifestyle interventions. All patients completed seven multi-factorial psychological, eating behavior, and quality-of-life questionnaires prior to choosing their weight loss treatment. Questionnaire scores, baseline body mass index, and percent weight loss at 1 year after surgical interventions were recorded. Surgical patients were younger, had a higher body mass index, and obesity had a higher impact on their quality of life than on non-surgical patients, but they did not differ in the majority of eating behavior and psychological parameters studied. Patients opting for adjustable gastric banding surgery were more anxious, depressed, and had more problems with energy levels than those choosing vertical sleeve gastrectomy, and more work problems compared to those undergoing gastric bypass. Weight loss after bariatric surgery was predicted by pre-operative scores of dietary restraint, disinhibition, and pre-surgery energy levels. The results of this study generate a number of hypotheses that can be explored in future studies and accelerate the development of personalized weight loss treatments. © The Finnish Surgical Society 2014.

    Abstract 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

    OBJECT Patients undergoing craniotomy are at risk for developing venous thromboembolism (VTE). The safety of anticoagulation in these patients is not clear. The authors sought to identify risk factors predictive of VTE in patients undergoing craniotomy. METHODS The authors reviewed a national surgical quality database, the American College of Surgeons National Surgical Quality Improvement Program. Craniotomy patients were identified by current procedural terminology code. Clinical factors were analyzed to identify associations with VTE. RESULTS Four thousand eight hundred forty-four adult patients who underwent craniotomy were identified. The rate of VTE in the cohort was 3.5%, including pulmonary embolism in 1.4% and deep venous thrombosis in 2.6%. A number of factors were found to be statistically significant in multivariate binary logistic regression analysis, including craniotomy for tumor, transfer from acute care hospital, age ≥ 60 years, dependent functional status, tumor involving the CNS, sepsis, emergency surgery, surgery time ≥ 4 hours, postoperative urinary tract infection, postoperative pneumonia, on ventilator ≥ 48 hours postoperatively, and return to the operating room. Patients were assigned a score based on how many of these factors they had (minimum score 0, maximum score 12). Increasing score was predictive of increased VTE incidence, as well as risk of mortality, and time from surgery to discharge. CONCLUSIONS Patients undergoing craniotomy are at low risk of developing VTE, but this risk is increased by preoperative medical comorbidities and postoperative complications. The presence of more of these clinical factors is associated with progressively increased VTE risk; patients possessing a VTE Risk Score of ≥ 5 had a greater than 20-fold increased risk of VTE compared with patients with a VTE score of 0.

    The purpose of this study was to conduct a systematic review of the available evidence on sleep disorders in patients with end stage renal disease (ESRD) undergoing hemodialysis (HD). [Subjects and Methods] Two independent reviewers performed a computer-assisted search of the MEDLINE, SciELO, LILACS, and BIREME Virtual Health Library medical databases from their inception to November 2015. [Results] One thousand one hundred twenty-six articles were found that met the inclusion criteria. Articles were excluded if they were not in English, the patients did not undergo HD, or the studies were not cross-sectional or clinical trials. After reading the full text, a further 300 studies were excluded because they did not use polysomnography. The remaining 18 studies with ESRD patients undergoing HD comprised 8 clinical trials and 10 cross-sectional studies. This systematic review followed the criteria outlined by the PRISMA declaration. [Conclusion] In this systematic review, a high prevalence of sleep disorders was observed in ESRD, including sleep-disordered breathing. This knowledge may enable health professionals to devise new strategies for the diagnosis and treatment of these patients, in order to reduce morbidity and mortality and improve their quality of life.

    It has often been hypothesized that mandibular setback surgery causes narrowing of the pharyngeal airway. We examined whether the pharyngeal airway narrowed after orthognathic surgery in patients undergoing either mandibular setback surgery or bimaxillary surgery and whether the amount of narrowing of the pharyngeal airway was any different after mandibular setback surgery or bimaxillary surgery. Cone-beam computed tomography scans were obtained for 21 patients who were assigned to either mandibular setback surgery or bimaxillary surgery. The anteroposterior dimension, lateral width, cross-sectional area, and volume of each subject's pharyngeal airway were measured before and after surgery. The pharyngeal airway showed significant narrowing after both mandibular setback surgery and bimaxillary surgery. The amount of change in the anteroposterior dimension and cross-sectional area on the posterior nasal spine plane and the length of the pharyngeal airway showed significant differences between the 2 groups. The amount of narrowing of the pharyngeal airway was smaller in patients undergoing bimaxillary surgery than in the patients undergoing mandibular setback surgery.

    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

    The optimal daptomycin dosing regimen for critically ill patients undergoing continuous renal replacement therapy (CRRT) has still to be established. Daptomycin pharmacokinetics was determined in 9 patients after administration of 6 mg/kg/day over 5 days. At steady state, which was reached by day 3, the area under the curve over 24 h (AUC24h) was 667.4 ± 356.6 mg·h/l, and the maximum concentration (Cmax) was 66.9 ±25.3 mg/l. Mean CRRT clearance accounted for 48% (range 32-67%) of total clearance (mean 10.2 ml/min, range 6.1-18 ml/min). Significant correlations were observed between Cmax, minimum concentration (Cmin) and AUC24h (R(2) = 0.91, p < 0.001, and R(2) = 0.94, p < 0.001) and between albumin plasma concentration and free daptomycin (R(2) = 0.7, p = 0.009). No significant accumulation occurred with a daily daptomycin dose of 6 mg/kg in patients undergoing CRRT with an effluent flow rate of >30 ml/kg/h. The quantification of trough concentrations (Cmin) appears to be a good surrogate to estimate AUC24h and to monitor daptomycin treatment in patients undergoing CRRT. © 2013 S. Karger AG, Basel.

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

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

    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. © 2013 Wiley Publishing Asia Pty Ltd.

    We present 2 patients with Moyamoya disease undergoing revascularization surgery who developed transient intraoperative central diabetes insipidus with spontaneous resolution in the immediate postoperative period. We speculate that patients with Moyamoya disease may be predisposed to a transient acute-on-chronic insult to the arginine vasopressin-producing portion of their hypothalamus mediated by anesthetic agents. We describe our management, discuss pertinent literature, and offer possible mechanisms of this transient insult. We hope to improve patient safety by raising awareness of this potentially catastrophic complication.

Association study based on in-hospital records and out-of-hospital pharmacotherapy use using a Danish nationwide cohort of patients with uncomplicated hypertension treated with at least 2 antihypertensive drugs (β-blockers, thiazides, calcium antagonists, or renin-angiotensin system [RAS] inhibitors) undergoing noncardiac surgery between 2005 and 2011. Various antihypertensive treatment regimens, chosen as part of usual care. Thirty-day risk of MACEs (cardiovascular death, nonfatal ischemic stroke, nonfatal myocardial infarction) and all-cause mortality, assessed using multivariable logistic regression models and adjusted numbers needed to harm (NNH). The baseline characteristics of the 14,644 patients who received β-blockers (65% female, mean [SD] age, 66.1 [12.0] years) were similar to those of the 40,676 patients who received other antihypertensive drugs (57% female, mean [SD] age, 65.9 [11.8] years). Thirty-day MACEs occurred in 1.3% of patients treated with β-blockers compared with 0.8% of patients not treated with β-blockers (P < .001). β-Blocker use was associated with increased risks of MACEs in 2-drug combinations with RAS inhibitors (odds ratio [OR], 2.16 [95% CI, 1.54-3.04]), calcium antagonists (OR, 2.17 [95% CI, 1.48-3.17]), and thiazides (OR, 1.56 [95% CI, 1.10-2.22]), compared with the reference combination of RAS inhibitors and thiazides. Results were similar for all-cause mortality. Risk of MACEs associated with β-blocker use seemed especially pronounced for patients at least 70 years old (number needed to harm [NNH], 140 [95% CI, 86-364]), for men (NNH, 142 [95% CI, 93-195]), and for patients

    AIM: To study a cohort of consecutive patients undergoing transcatheter aortic valve implantation (TAVI) and compare the outcomes of atrial fibrillation (AF) patients vs patients in sinus rhythm (SR). METHODS: All consecutive patients undergoing TAVI in our hospital were included. The AF group comprised patients in AF at the time of TAVI or with history of AF, and were compared with the SR group. Procedural, echocardiographic and follow-up variables were compared. Likewise, the CHA2DS2-VASC stroke risk score and HAS-BLED bleeding risk score and antithrombotic treatment at discharge in AF patients were compared with that in SR patients. RESULTS: From a total of 34 patients undergoing TAVI, 17 (50%) were allocated to the AF group, of whom 15 (88%) were under chronic oral anticoagulation. Patients in the AF group were similar to those in the SR group except for a trend (P = 0.07) for a higher logistic EuroSCORE (28% vs 19%), and a higher prevalence of hypertension (82% vs 53%) and chronic renal failure (17% vs 0%). Risk of both stroke and bleeding was high in the AF group (mean CHA2DS2-VASC 4.3, mean HAS-BLED 2.9). In the AF group, treatment at discharge included chronic oral anticoagulation in all except one case, and in association with an antiplatelet drug in 57% of patients. During a mean follow-up of 11 mo (maximum 32), there were only two strokes, none of them during the peri-procedural period: one in the AF group at 30 mo and one in the SR group at 3 mo. There were no statistical differences in procedural success, and clinical outcome (survival at 1 year 81% vs 74% in AF and SR groups, respectively, P = NS). CONCLUSION: Patients in AF undergoing TAVI show a trend to a higher surgical risk. However, in our cohort, patients in AF did not have a higher stroke rate compared to the SR group, and the prognosis was similar in both groups. PMID:22279599

    Due to their unique pathophysiological profile, patients with hypertrophic cardiomyopathy (HCM) undergoing non-cardiac surgery require additional attention to perioperative management. We sought to compare perioperative outcomes of patients with HCM undergoing non-cardiac surgery with a matched group patients without HCM. This observational cohort study conducted at a tertiary care centre included patients with HCM (n=92, age 67 years, 54% men) undergoing intermediate-risk and high-risk non-cardiac surgeries between 1/2007 and 12/2013 (excluding <18 years, prior septal myectomy/alcohol ablation, low-risk surgery) who were 1:2 matched (based on age, gender, type and time of non-cardiac surgery) with patients without HCM (n=184, median age 65 years, 53% men). A composite endpoint (30-day postoperative death, myocardial infarction, stroke, in-hospital decompensated congestive heart failure (CHF) and rehospitalisation within 30 days) and postoperative atrial fibrillation (AF) were recorded. There was a significantly lower incidence of intraoperative hypotension/tachycardia in patients with HCM versus those without HCM (p<0.001). At 30 days postoperatively, 42 (15%) patients had composite events. Rates of 30-day death, MI or stroke were very low in patients with HCM (5%). However, a significantly higher proportion of patients with HCM met the composite endpoint versus patients without HCM (20 (22%) vs 22 (12%), p=0.03), driven by decompensated CHF. On logistic regression, HCM, high-risk non-cardiac surgery, high anaesthesia risk score and intraoperative duration of hypotension were independently associated with 30-day composite events (p<0.05). Patients with HCM undergoing high-risk and intermediate-risk non-cardiac surgeries have a low perioperative event rate, at an experienced centre. However, they have a higher risk of composite events versus matched patients without HCM. Published by the BMJ Publishing Group Limited. For permission to use (where not already

    OBJECTIVE: To study a strategy of aggressive coronary balloon angioplasty with provisional stenting in allcomers. In randomized trials, stenting has improved the outcome of patients undergoing coronary intervention. However, whether these results hold up in clinical practice is largely unknown. Furthermore, the results of balloon angioplasty have also improved dramatically. It is therefore essential to evaluate the current results of balloon angioplasty and to assess whether stents are required in all patients. METHODS: The authors prospectively studied the occurrence of death, myocardial infarction (MI) and target lesion revascularization (TLR) of a large consecutive group of patients undergoing aggressive balloon angioplasty with provisional stenting. None of the patients received a platelet glycoprotein IIb/IIIa receptor blocker. The results were compared with the outcome of routine stenting in recent randomized trials. RESULTS: Angioplasty was performed in 1058 patients of whom 369 (34.9%) received a stent. The angiographic success rate was 98.9%. During hospital stay, 4.8% of the patients suffered any cardiac event. At one-year follow-up, death occurred in 1.1%, MI in 3.3%, TLR in 12.4% and any event in 16.7% of the patients. Event-free survival at one-year was 82.3%. These results compare favorably with routine stenting in recent trials. CONCLUSIONS: Aggressive balloon angioplasty with provisional stenting yields excellent results in a general patient population.

    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.

    Background and purpose — Recent evidence has questioned the effect of arthroscopic knee surgery for middle-aged and older patients with degenerative meniscal tears with or without concomitant radiographic knee osteoarthritis (OA). We investigated the prevalence of early or more established knee OA and patients’ characteristics in a cohort of patients undergoing arthroscopic surgery for a meniscal tear. Patients and methods — 641 patients assigned for arthroscopy on suspicion of meniscus tear were consecutively recruited from February 2013 through January 2015. Of these, 620 patients (mean age 49 (18–77) years, 57% men) with full datasets available were included in the present study. Prior to surgery, patients completed questionnaires regarding onset of symptoms, duration of symptoms, and mechanical symptoms along with the knee injury and osteoarthritis outcome score (KOOS). At arthroscopy, the operating surgeon recorded information about meniscal pathology and cartilage damage. Early or more established knee OA was defined as the combination of self-reported frequent knee pain, cartilage damage, and the presence of degenerative meniscal tissue. Results — 43% of patients (269 of 620) had early or more established knee OA. Of these, a large proportion had severe cartilage lesions with almost half having a severe cartilage lesion in at least 1 knee compartment. Interpretation — Based on a definition including frequent knee pain, cartilage damage, and degenerative meniscal tissue, early or more established knee OA was present in 43% of patients undergoing knee arthroscopy for meniscal tear.

    Sleep is one of the most fundamental human needs; without any doubt sleep is even more essential for sick patients, especially for patients with chronic illnesses. Sleep disturbance may lead to anxiety and reduced quality of life. Restless leg syndrome (RLS) is a sensory-motor disorder accompanied by a strong desire to move the legs or other parts of the body, which can cause sleep disturbance. Its etiology is unknown, but increased urea and creatinine levels before dialysis, iron deficiency due to kidney failure and end-stage renal disease (ESRD) are mentioned as causes. This study is designed to examine the prevalence of insomnia and restless leg syndrome in patients undergoing chronic hemodialysis in Rafsanjan Ali Ibn Abitaleb Hospital. In this study we used two questionnaires to evaluate the presence of RLS and insomnia in ESRD patients who were undergoing hemodialysis treatment as kidney replacement therapy. According to our results, 54.5% of patients were diagnosed with RLS, and of those 65.2% and 42.9% were women and men, respectively. RLS is seen more often among patients with blood group type A, but this result was not statistically significant. There was a statistically significant correlation between RLS and a positive family history of RLS, between RLS and the number of hemodialysis treatments per week and also between RLS and the Insomnia Severity Index. Unlike previous studies, in this study we did not find any statistically significant correlation between RLS and biochemical factors such as serum iron, TIBC, BUN, creatinine, potassium, calcium and phosphorous levels. The frequency of RLS among our patients was remarkable and we conclude that all patients who are undergoing hemodialysis should be screened for RLS, which can assist in providing proper attention and treatment.

    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

    Summary Background and objectives The fixed antibacterial combination of ampicillin and sulbactam is frequently used for various infections. Intact kidneys eliminate approximately 71% of ampicillin and 78% of sulbactam. Patients on thrice-weekly low-flux hemodialysis exhibit an ampicillin t1/2 of 2.3 hours on and 17.4 hours off dialysis. Despite its frequent use in intensive care units, there are no available dosing recommendations for patients with AKI undergoing renal replacement therapy. The aims of this study were to evaluate the pharmacokinetics of ampicillin/sulbactam in critically ill patients with AKI undergoing extended dialysis (ED) and to establish a dosing recommendation for this treatment method. Design, setting, participants, & measurements Twelve critically ill patients with anuric AKI being treated with ED were enrolled in a prospective, open-label, observational pharmacokinetic study. Pharmacokinetics after a single dose of ampicillin/sulbactam (2 g/1 g) was obtained in 12 patients. Multiple-dose pharmacokinetics after 4 days of twice-daily ampicillin/sulbactam (2 g/1 g) was obtained in three patients. Results The mean dialyzer clearance for ampicillin/sulbactam was 80.1±7.7/83.3±12.1 ml/min. The t1/2 of ampicillin and sulbactam in patients with AKI undergoing ED were 2.8±0.8 hours and 3.5±1.5 hours, respectively. There was no significant accumulation using a twice-daily dosage of 2 g/1 g ampicillin/sulbactam. Conclusions Our data suggest that in patients treated with ED using a high-flux dialyzer (polysulphone, 1.3 m2; blood and dialysate flow, 160 ml/min; treatment time, 480 minutes), a twice-daily dosing schedule of at least 2 g/1 g ampicillin/sulbactam, with one dose given after ED, should be used to avoid underdosing.

    Studies have individually reported the relationship of age, cardiac risk factors, and history of preexisting coronary artery disease (CAD) for predicting acute coronary syndromes in chest pain patients undergoing cardiac stress testing. In this study, we investigate the interplay of all these factors on the incidence of acute coronary syndromes to develop a tool that may assist physicians in the selection of appropriate chest pain patients for stress testing. Retrospective analysis of a prospectively acquired database of consecutive chest pain patients undergoing nuclear stress testing. Backward stepwise logistic regression was used to develop a model for predicting risk of 30-day acute coronary events (ACE) using information obtained from age, sex, cardiac risk factors, and history of preexisting CAD. A total of 800 chest pain patients underwent nuclear stress testing. ACE occurred in 74 patients (9.3%). Logistic regression analysis found only 6 factors predictive of ACE: age, male sex, preexisting CAD, diabetes, and hyperlipidemia. Area under the receiver operator characteristic curve of this model for predicting ACE was 0.767 (95% confidence interval, 0.719-0.815). There were no cases of ACE in the 173 patients with predicted probability estimates ≤2.5% (95% confidence interval, 0%-2.1%). A regression model using age, sex, preexisting CAD, diabetes, and hyperlipidemia is predictive of 30-day ACE in chest pain patients undergoing nuclear stress testing. Prospective studies need to be performed to determine whether this model can assist physicians in the selection of appropriate low-to-intermediate risk chest pain patients for nuclear stress testing.

    This study evaluated the effects of handholding and spoken information provided on the anxiety of patients undergoing percutaneous vertebroplasty under local anaesthesia. A surgical intervention usually entails physical discomfort and psychological burden. Furthermore, patients under local anaesthesia are conscious during the surgical intervention, which leads to more anxiety, as patients are aware of their surroundings in the operating theatre. A quasi-experimental design with a nonequivalent control group was utilised. Amsterdam preoperative anxiety scale assessed psychological anxiety, while blood pressure and pulse were measured to evaluate physiological anxiety. Participants were 94 patients undergoing percutaneous vertebroplasty in a spine hospital in Gwangju Metropolitan City, South Korea. Thirty patients were assigned to Experimental Group I, 34 to the Experimental Group II and 30 to the control group. During a surgical intervention, nurses held the hands of those in Experimental Group I and provided them with spoken information. Patients in Experimental Group II experienced only handholding. Psychological anxiety in Experimental Group I was low compared to those in Experimental Group II and the control group. In addition, there were significant decreases in systolic blood pressure in both Experimental Groups compared to the control group. Handholding and spoken information provided during a surgical intervention to mitigate psychological anxiety, and handholding to mitigate physiological anxiety can be used in nursing interventions with patients undergoing percutaneous vertebroplasty. Handholding and providing nursing information are possibly very useful interventions that are easily implemented by circulating nurses during a surgical intervention. In particular, handholding is a simple, economical and appropriate way to help patient in the operating theatre. © 2015 John Wiley & Sons Ltd.

    Malabsorptive techniques, such as biliopancreatic diversion, described by Scopinaro, can cause disabling steatorrhea that affects patients' quality of life. Although it usually improves over time, a reduced group of patients can require treatment. The objective of the present study was to assess the effects of bismuth subgallate on the quality of life (QoL) of patients undergoing Scopinaro's biliopancreatic diversion (SBPD) for morbid obesity. The study was conducted at the Hospital Universitario Insular de Gran Canaria, Spain, a public hospital. A prospective, observational study in clinical practice was performed to ascertain the effects of bismuth subgallate on QoL in a group of patients undergoing SBPD who reported disabling diarrhea and related odor. Patients received treatment with 2 courses of oral bismuth subgallate, 200 mg every 8 hours for 12 weeks, with a 4-week rest period. Pretreatment and posttreatment surveys were performed. The Gastrointestinal Quality of Life Index (GIQLI) questionnaire was used, which evaluates symptoms, physical status, emotional status, social performance, and treatment effects. Sixty patients--90% women--with a mean age of 45.6 years were included in the study, 65% of which had superobesity. GIQLI scores obtained at treatment completion were significantly higher--both overall and in the various domains--than those obtained before treatment onset (P<.01). When the morbid obesity and superobesity groups were analyzed separately, a significant increase in the scores for both patient groups was also observed (P< .01). In clinical practice, treatment with bismuth subgallate resulted in a short-term improvement of QoL for patients undergoing SBPD. Copyright © 2015 American Society for Bariatric Surgery.

    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.

    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

    Cardiopulmonary bypass initiates a systemic inflammatory response syndrome that is associated with postoperative morbidity and mortality. Steroids suppress inflammatory responses and might improve outcomes in patients at high risk of morbidity and mortality undergoing cardiopulmonary bypass. We aimed to assess the effects of steroids in patients at high risk of morbidity and mortality undergoing cardiopulmonary bypass. The Steroids In caRdiac Surgery (SIRS) study is a double-blind, randomised, controlled trial. We used a central computerised phone or interactive web system to randomly assign (1:1) patients at high risk of morbidity and mortality from 80 hospital or cardiac surgery centres in 18 countries undergoing cardiac surgery with the use of cardiopulmonary bypass to receive either methylprednisolone (250 mg at anaesthetic induction and 250 mg at initiation of cardiopulmonary bypass) or placebo. Patients were assigned with block randomisation with random block sizes of 2, 4, or 6 and stratified by centre. Patients aged 18 years or older were eligible if they had a European System for Cardiac Operative Risk Evaluation of at least 6. Patients were excluded if they were taking or expected to receive systemic steroids in the immediate postoperative period or had a history of bacterial or fungal infection in the preceding 30 days. Patients, caregivers, and those assessing outcomes were masked to allocation. The primary outcomes were 30-day mortality and a composite of death and major morbidity (ie, myocardial injury, stroke, renal failure, or respiratory failure) within 30 days, both analysed by intention to treat. Safety outcomes were also analysed by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00427388. Patients were recruited between June 21, 2007, and Dec 19, 2013. Complete 30-day data was available for all 7507 patients randomly assigned to methylprednisolone (n=3755) and to placebo (n=3752). Methylprednisolone, compared

    The National Early Warning Score (NEWS) aids the early recognition of those at risk of becoming critically ill. NEWS has been recommended for use by ambulance services, but very little work has been undertaken to date to determine its suitability. This paper examines whether a prehospital NEWS derived from ambulance service clinical observations is associated with the hospital ED disposition. Prehospital NEWS was retrospectively calculated from the ambulance service clinical records of 287 patients who were treated by the ambulance service and transported to hospital. In this cohort study, derived NEWS scores were compared with ED disposition data and patients were categorised into the following groups depending on their outcome: discharged from ED, admitted to a ward, admitted to intensive therapy unit (ITU) or died. Prehospital NEWS-based ambulance service clinical observations were significantly associated with discharge disposition groups (p<0.001), with scores escalating in line with increasing severity of outcome. Patients who died or were admitted to ITU had higher scores than those admitted to a ward or discharged from ED (mean NEWS 7.2 and 7.5 vs 2.6 and 1.7, respectively), and in turn those who were admitted to a ward had higher pre-hospital NEWS than those who were discharged (2.6 vs 1.7). Our findings suggest that the NEWS could successfully be used by ambulance services to identify patients most at risk from subsequent deterioration. The implementation of this early warning system has the potential to support ambulance clinician decision making, providing an additional tool to identify and appropriately escalate care for acutely unwell patients. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    OBJECTIVE Depression is the most prevalent affective disorder in the US, and patients with spinal deformity are at increased risk. Postoperative delirium has been associated with inferior surgical outcomes, including morbidity and mortality. The relationship between depression and postoperative delirium in patients undergoing spine surgery is relatively unknown. The aim of this study was to determine if depression is an independent risk factor for the development of postoperative delirium in patients undergoing decompression and fusion for deformity. METHODS The medical records of 923 adult patients (age ≥ 18 years) undergoing elective spine surgery at a single major academic institution from 2005 through 2015 were reviewed. Of these patients, 255 (27.6%) patients had been diagnosed with depression by a board-certified psychiatrist and constituted the Depression group; the remaining 668 patients constituted the No-Depression group. Patient demographics, comorbidities, and intra- and postoperative complication rates were collected for each patient and compared between groups. The primary outcome investigated in this study was rate of postoperative delirium, according to DSM-V criteria, during initial hospital stay after surgery. The association between depression and postoperative delirium rate was assessed via multivariate logistic regression analysis. RESULTS Patient demographics and comorbidities other than depression were similar in the 2 groups. In the Depression group, 85.1% of the patients were taking an antidepressant prior to surgery. There were no significant between-group differences in intraoperative variables and rates of complications other than delirium. Postoperative complication rates were also similar between the cohorts, including rates of urinary tract infection, fever, deep and superficial surgical site infection, pulmonary embolism, deep vein thrombosis, urinary retention, and proportion of patients transferred to the intensive care unit.

    Survival rates are poorer after a second hip fracture than after a first hip fracture. Previous survival studies have included in-hospital mortality. Excluding in-hospital deaths from the analysis allows survival times to be evaluated in community-based patients. There is still a lack of data regarding the effects of subsequent fractures on survival times after hospital discharge following an initial hip fracture. This study compared the survival times of community-dwelling patients with hip fracture who had or did not have a subsequent major long-bone fracture. Hazard ratios and risk factors for subsequent fractures and mortality rates with and without subsequent fractures were calculated. Of 844 patients with hip fracture from 2000 through 2008, 71 had a subsequent major long-bone fracture and 773 did not. Patients who died of other causes, such as perioperative complications, during hospitalization were excluded. Such exclusion allowed us to determine the effect of subsequent fracture on the survival of community-dwelling individuals after hospital discharge or after the time of the fracture if they did not need hospitalization. Demographic data, causes of death, and mortality rates were recorded. Differences in mortality rates between the patient groups and hazard ratios were calculated. Mortality rates during the first year and from 1 to 5 years after the most recent fracture were 5.6% and 1.4%, respectively, in patients with subsequent fractures, and 4.7% and 1.4%, respectively, in patients without subsequent fractures. These rates did not differ significantly between the groups. Cox regression analysis and calculation of hazard ratios did not show significant differences between patients with subsequent fractures and those without. On univariate and multivariate analyses, age <75 years and male sex were risk factors for subsequent fracture. This study found that survival times did not differ significantly between patients with and without subsequent major

    Because of its reduced invasiveness, MitraClip (Abbott Vascular, Menlo Park, CA) therapy usually is reserved for patients with extreme left ventricular dysfunction or severe comorbidity contraindicating surgery. The appropriate post-procedural care in this high-risk population is yet to be defined. In this study, the postoperative course of such patients is reported, focusing on early complications and need for intensive care unit (ICU) management. A retrospective analysis of patients with severe mitral regurgitation undergoing transcatheter mitral valve repair with the MitraClip system in the authors institution was performed. One hundred thirty patients underwent MitraClip implantation between 2008 and 2012. At the end of the procedure, all patients were admitted to the ICU. Median ICU stay was 0.98 (0.82-1.87) days. Median mechanical ventilation time was 9.5 (6.8-14.1) hours. One hundred one patients (78%) required inotropic support and 13 patients (10%) suffered cardiogenic shock and required intra-aortic balloon pump support. No patient died during the procedure, but 3 patients died in the ICU. Three postoperative course profiles were identified: Fast-track, overnight stay, and critical illness. Twenty-four patients (18.5%) had an uneventful postoperative course, 89 patients (68.5%) suffered minor complications, and 17 patients (13.1%) required intensive care management and organ support. Preoperative serum creatinine (odds ratio [OR] 1.8; p = 0.014), cardiogenic shock (OR 34,8; p = 0.002), ventricular tachycardia (OR 2.8; p = 0.03), and intra procedural inotropes (OR 4; p = 0.001) were correlated with a complicated postoperative course. A large number of patients undergoing MitraClip could be managed with a fast-track ICU course; however, it still is difficult to predict the postoperative course based on preoperative characteristics.

    To investigate a recent association between the use of the angiotensin receptor-blocker (ARB) olmesartan and a severe enteropathy resembling celiac disease. We searched our endoscopy database for all outpatient esophagogastroduodenoscopy (EGD) or colonoscopy examinations in patients aged at least 50 years during the period January 1, 2007, to March 31, 2013. Cases were those whose examination indication was diarrhea, and controls were those whose examination indication was esophageal reflux (EGD) or colorectal cancer screening (colonoscopy). We compared cases with controls with regard to the proportion of those listing olmesartan among their medications. Secondary exposures were the proportion of those taking nonolmesartan ARBs or other antihypertensive medications. We also examined biopsy results to determine whether there were histologic changes associated with the use of olmesartan. We identified 2088 patients undergoing EGD and 12,428 patients undergoing colonoscopy meeting inclusion criteria. On multivariate analysis, there was no statistically significant association between olmesartan and diarrhea among those undergoing EGD (odds ratio, 1.99; 95% CI, 0.79-5.00) or colonoscopy (odds ratio, 0.63; 95% CI, 0.23-1.74). Review of pathology reports of the EGD and colonoscopy groups showed no association between the use of olmesartan and the histologic diagnosis of celiac disease (P=.61) or microscopic colitis (P=1.0), respectively. Our findings suggest that neither olmesartan nor other ARBs were associated with diarrhea among patients undergoing endoscopy. The spruelike enteropathy recently associated with olmesartan is likely a rare adverse effect and milder presentations are unlikely.
