    Background Acute exacerbation of chronic obstructive pulmonary disease (COPD) causes not only an accelerated disease progression, but also an increased mortality rate. The purpose of this study was to analyze the factors associated with clinical features, comorbidities and mortality in patients at high risk for acute COPD exacerbation who had been hospitalized at least once in a year. Methods The study enrolled 606 patients who had been diagnosed with and were being treated for COPD at university affiliated hospital. Among them, there were 61 patients at high risk for acute exacerbation of COPD who had been hospitalized at least once in a year. A retrospective analysis was conducted to examine the factors affecting mortality. The analysis divided the patients into non-survivor and survivor groups, and reviewed their medical records for clinical aspects, comorbidities, pulmonary function tests and blood tests. Results In the high-risk group, the number of comorbidities at diagnosis (P = 0.020) and the Charlson comorbidity index value (P = 0.018) were higher in the non-survivor group than in the survivor group. During hospitalization, the non-survivor group had a significantly higher neutrophil (%) and a significantly lower lymphocyte (%) in complete blood count. Under stable conditions, the high-sensitivity C-reactive protein (hsCRP) concentration in blood plasma and neutrophil (%) were significantly higher (P = 0.025 and P = 0.036), while the lymphocyte (%) was significantly lower (P = 0.005) in the non-survivor group. A pulmonary function test revealed no statistically significant differences between the two groups. Conclusion The number of comorbidities, neutrophil (%), lymphocyte (%) in complete blood cell (CBC) and hsCRP in blood plasma concentration among the groups at high risk for COPD exacerbation are associated with increased mortality.

    A prospective comparison of chest radiography, conventional tomography, and computed tomography (CT) in the detection or confirmation of solitary pulmonary nodules was made in 42 patients with high propensity for pulmonary metastases due to advanced local (Clark level IV or V) or regional malignant melanoma. Unequivocal nodules were revealed by chest radiography in 11 patients, conventional tomograhy in 16, and computed tomography in 20 patients. Both plain films and tomography in three of these 20 were normal, but follow-up verified pulmonary metastases. Computed tomography detected more pulmonary nodules than conventional tomography in 11 patients in addition to identifying lesions in extrapulmonary sites. Therefore, chest CT is recommended before institution of immunotherapy or surgical removal of a solitary pulmonary melanoma metastasis. Once chemotherapy had been instituted for bulky regional or cutaneous involvement, however, the findings of either conventional or computed tomography were comparable in this study.

    In a previous study, the authors reported the clinical and radiological results of Duchenne muscular dystrophy (DMD) scoliosis surgery in 14 patients with a low FVC of <30%. The purpose of this study was to determine if surgery improved function and QOL in these patients. Furthermore, the authors assessed the patients’ and parents’ satisfaction. %FVC increased in all patients after preoperative inspiratory muscle training. Scoliosis surgery in this group of patients presented no increased risk of major complications. All-screw constructions and fusion offered the ability to correct spinal deformity in the coronal and pelvic obliquity initially, intermediate and long-term. All patients were encouraged to continue inspiratory muscle training after surgery. The mean rate of %FVC decline after surgery was 3.6% per year. Most patients and parents believed scoliosis surgery improved their function, sitting balance and quality of life even though patients were at high risk for major complications. Their satisfaction was also high. PMID:20155495

    Background Neutrophil products like matrix metalloproteinases (MMP), involved in bacterial defence mechanisms, possibly induce lung damage and are elevated locally during hospital- acquired pneumonia (HAP). In HAP the virulence of bacterial species is known to be different. The aim of this study was to investigate the influence of high-risk bacteria like S. aureus and pseudomonas species on pulmonary MMPconcentration in human pneumonia. Methods In 37 patients with HAP and 16 controls, MMP-8, MMP-9 and tissue inhibitors of MMP (TIMP) were analysed by ELISA and MMP-9 activity using zymography in bronchoalveolar lavage (BAL). Results MMP-9 activity in mini-BAL was increased in HAP patients versus controls (149 ± 41 vs. 34 ± 11, p < 0.0001). In subgroup analysis, the highest MMP concentrations and activity were seen in patients with high-risk bacteria: patients with high-risk bacteria MMP-9 1168 ± 266 vs. patients with low-risk bacteria 224 ± 119 ng/ml p < 0.0001, MMP-9 gelatinolytic activity 325 ± 106 vs. 67 ± 14, p < 0.0002. In addition, the MMP-8 and MMP-9 concentration was associated with the state of ventilation and systemic inflammatory marker like CRP. Conclusion Pulmonary MMP concentrations and MMP activity are elevated in patients with HAP. This effect is most pronounced in patients with high-risk bacteria. Artificial ventilation may play an additional role in protease activation. PMID:18700005

    Cardioplegic reperfusion during a long term ischemic period interrupts cardiac surgery and also increases cellular edema due to repeated solution administration. We reviewed the clinical experiences on myocardial protection of a single perfusion with histidine-tryptophan-ketoglutarate (HTK) for high-risk patients with severe pulmonary arterial hypertension associated with complex congenital heart disease. This retrospective study included 101 high-risk patients undergoing arterial switch operation between March 2001 and July 2012. We divided the cohort into two groups: HTK group, myocardial protection was carried out with one single perfusion with HTK solution; and St group, myocardial protection with conventional St. Thomas' crystalloid cardioplegic solution. The duration of cardiopulmonary bypass did not differ between the two groups. The mortality, morbidity, ICU stay, post-operative hospitalization time, and number of transfusions in HTK group were lower than those in St group (P<0.05). Univariate and multivariate analysis showed that HTK is a statistically significant independent predictor of decreased early mortality and morbidity (P<0.05). In conclusion, HTK solution seems to be an effective and safe alternative to St. Thomas' solution for cardioplegic reperfusion in high-risk patients with complex congenital heart disease.

    We compared the prognostic performance of the 2014 European Society of Cardiology (ESC) risk stratification algorithm with the previous 2008 ESC algorithm, the Bova score and the modified FAST score (based on a positive heart-type fatty acid-binding protein (H-FABP) test, syncope and tachycardia, modified using high-sensitivity troponin T instead of H-FABP) in 388 normotensive pulmonary embolism patients included in a single-centre cohort study.Overall, 25 patients (6.4%) had an adverse 30-day outcome. Regardless of the score or algorithm used, the rate of an adverse outcome was highest in the intermediate-high-risk classes, while all patients classified as low-risk had a favourable outcome (no pulmonary embolism-related deaths, 0-1.4% adverse outcome). The area under the curve for predicting an adverse outcome was higher for the 2014 ESC algorithm (0.76, 95% CI 0.68-0.84) compared with the 2008 ESC algorithm (0.65, 95% CI 0.56-0.73) and highest for the modified FAST score (0.82, 95% CI 0.75-0.89). Patients classified as intermediate-high-risk by the 2014 ESC algorithm had a 8.9-fold increased risk for an adverse outcome (3.2-24.2, p<0.001 compared with intermediate-low- and low-risk patients), while the highest OR was observed for a modified FAST score ≥3 points (OR 15.9, 95% CI 5.3-47.6, p<0.001).The 2014 ESC algorithm improves risk stratification of not-high-risk pulmonary embolism compared with the 2008 ESC algorithm. All scores and algorithms accurately identified low-risk patients, while the modified FAST score appears more suitable to identify intermediate-high-risk patients. PMID:26743479

    In this study, controllability, safety, blood cell depletion, and hemolysis of a pulsatile roller pump in high-risk patients was evaluated. Sarns 8000 roller pump (Sams, Terumo CVS, Ann Arbor, MI, USA) with a pulsatile control module was used as arterial pump in a clinical setting. Forty patients undergoing elective open heart surgery with high-risk either having chronically obstructive pulmonary disease or chronic renal failure were randomly included in the study to be operated on using pulsatile perfusion or non-pulsatile perfusion. Blood samples were withdrawn at induction of anesthesia, at the time of aortic clamping and de-clamping and at 1 hour and 24 hours following cessation of the bypass. Hematocrit and plasma free hemoglobin values were measured. We observed that the pulsatile roller pump perfusion and the extracorporeal circuit used in the clinical study is safe in high-risk patients undergoing cardiopulmonary bypass. We did not face any emboli, hemolysis, or technical problems. Pulsatile roller pump perfusion with Sarns 8000 heart-lung machine is a simple and reliable technique and can be easily applied during open heart surgery. PMID:15202823

    Background Pulmonary embolism (PE) with more than 50% compromise of pulmonary circulation results significant right ventricular (RV) afterload leading to progressive RV failure, systemic hypotension and shock. Prompt restoration of thrombolysis, surgical embolectomy, or percutaneous mechanical thrombectomy (PMT) prevents progressive hemodynamic decline. We report our single center experience in high risk PE patients treated with standard pigtail catheter mechanical fragmentation followed by intrapulmonary thrombolysis as a primary therapy. Methods 50 consecutive patients with diagnosis of high risk PE defined as having shock index >1 with angiographic evidence of >50% pulmonary arterial occlusion are included in the present study. All patients underwent emergent cardiac catheterization. After ensuring flow across pulmonary artery with mechanical breakdown of embolus by rotating 5F pigtail catheter; bolus dose of urokinase (4400 IU/kg) followed by infusion for 24 h was given in the thrombus. Hemodynamic parameters were recorded and follow up pulmonary angiogram was done. Clinical and echo follow up was done for one year. Results Pigtail rotational mechanical thrombectomy restored antegrade flow in all patients. The mean pulmonary artery pressure, Miller score, Shock index decreased significantly from 41 ± 8 mmHg, 20 ± 5, 1.32 ± 0.3 to 24.52 ± 6.89, 5.35 ± 2.16, 0.79 ± 0.21 respectively (p < 0.0001). In-hospital major complications were seen in 4 patients. There was a statistically significant reduction of PA pressures from 62 ± 11 mmHg to 23±6 mmHg on follow up. Conclusions Rapid reperfusion of pulmonary arteries with mechanical fragmentation by pigtail catheter followed by intrapulmonary thrombolysis results in excellent immediate and intermediate term outcomes in patients presenting with high risk pulmonary embolism.

    Postoperative mortality remains alarmingly high with a mortality rate ranging between 0.4% and 4%. A small subgroup of multimorbid and/or elderly patients undergoing different surgical procedures naturally confers the highest risk of complications and perioperative death. Therefore, preoperative assessment should identify these high-risk patients and stratify them to individualized monitoring and treatment throughout all phases of perioperative care. A "tailored" perioperative approach might help further reduce perioperative morbidity and mortality. This article aims to elucidate individual morbidity-specific risks. It further suggests approaches to detect patients at the risk of perioperative complications. PMID:27396802

    Hernia formation after surgical procedures continues to be an important cause of surgical morbidity. Incisional reinforcement at the time of the initial operation has been used in some patient populations to reduce the risk of subsequent hernia formation. In this article, reinforcement techniques in different surgical wounds are examined to identify situations in which hernia formation may be prevented. Mesh use for midline closure, pelvic floor reconstruction, and stoma site reinforcement is discussed. Additionally, the use of retention sutures, closure of the open abdomen, and reinforcement after component separation are examined using current literature. Although existing studies do not support the routine use of mesh reinforcement for all surgical incisions, certain patient populations appear to benefit from reinforcement with lower rates of subsequent hernia formation. The identification and characterization of these groups will guide the future use of mesh reinforcement in surgical incisions. PMID:25435823

    This study's purpose was to present the use of a risk stratification protocol in which "routine" risk patients receive a mobile compression device with aspirin and "high" risk patients receive warfarin for thromboprophylaxis after hip arthroplasty. 1859 hip arthroplasty patients were prospectively enrolled (1402 routine risk--75.4%, 457 high risk--24.6%). The cumulative rate of venous thromboembolism events was 0.5% in the routine versus 0.5% in the high-risk cohort within 6weeks postoperatively (P=1.00). Patients in the routine risk cohort had a lower rate of major bleeding (0.5% versus 2.0%, P=0.006) and wound complications (0.2% versus 1.2%, P=0.01). Use of our risk stratification protocol allowed the avoidance of more aggressive anticoagulation in 75% of patients while achieving a low overall incidence of symptomatic VTE. PMID:26182980

    Elderly and high-risk patients are increasingly being considered for myocardial revascularisation. Most trials comparing the various options for revascularisation exclude elderly and 'high-risk' patients. We have reviewed the options for myocardial revascularisation for elderly patients, and for patients with a number of common 'high-risk' co-morbidities--diabetes mellitus, renal insufficiency, poor left ventricular ejection fraction, peripheral vascular disease, left main coronary artery disease and chronic obstructive pulmonary disease--with a focus on coronary artery bypass grafting without the use of cardiopulmonary bypass and aortic manipulation.

    Lipid-lowering agents have been shown to reduce morbidity and mortality associated with coronary heart disease (CHD), particularly in high-risk patients. The identification and treatment of these patients should therefore be a high priority for clinicians. Guidelines from medical organizations, such as the National Cholesterol Education Program Adult Treatment Panel (NCEP ATP) and the American Diabetes Association (ADA), suggest that patients with low-density lipoprotein cholesterol (LDL-C) levels > or =130 mg/dL, and perhaps even those with levels > or =100 mg/dL, should receive drug therapy. Optimal LDL-C levels have been set at <100 mg/dL and <115 mg/dL for high-risk patients by US and European guidelines, respectively. However, a recent survey shows that only about 20% of high-risk patients currently meet these goals. In order to achieve therapeutic targets for LDL-C, the statins are the foundation of treatment, as they are the most effective and best-tolerated form of lipid-lowering therapy. Other therapeutic options include bile acid sequestrants, niacin, and plant stanols, although seldom as monotherapy. Combination therapy with a statin and one of these other lipid-lowering agents can be useful in patients who are unable to achieve target lipid levels through monotherapy. There remains, however, a need for additional agents. Some of the new options for reducing LDL-C levels that may be available in the near future include 2 new statins, pitavastatin and rosuvastatin. In patients with heterozygous familial hypercholesterolemia, rosuvastatin, which is currently under review by the Food and Drug Administration (FDA), has been shown to produce significantly greater reductions in LDL-C than atorvastatin over its full dose range. In comparative clinical trials, it has also enabled more patients with primary hypercholesterolemia to meet lipid goals than atorvastatin, simvastatin, and pravastatin. Inhibitors of bile acid transport or cholesterol absorption may also

    Aspergillosis mortality has risen exponentially over the last 2 decades, related primarily to the availability of medical treatments and procedures that prolong the survival of patients with other disorders who are at high risk because of immunologic compromise. In addition to excess mortality, aspergillosis results in increased costs for hospitalization and treatment, including management of adverse events associated with conventional amphotericin B treatment. Compared with amphotericin B, the triazole antifungal voriconazole has excellent efficacy and a favorable side-effect profile. Reliable oral bioavailability of voriconazole may permit switching to an oral formulation in the inpatient setting and offers the possibility of earlier hospital discharge and potentially substantial cost savings.

    The risk of pulmonary infarction in any hospitalized population is high. To decrease this dreaded complication, the high risk population must be identified. These are chiefly elderly patients with a history of previous DVTP, cancer, cardiac disease, trauma to a lower limb or a history of recent surgery.

    Recently, RECQL was reported as a new breast cancer susceptibility gene. RECQL belongs to the RECQ DNA helicase family which unwinds double strand DNA and involved in the DNA replication stress response, telomere maintenance and DNA repair. RECQL deficient mice cells are prone to spontaneous chromosomal instability and aneuploidy, suggesting a tumor-suppressive role of RECQL in cancer. In this study, RECQL gene mutation screening was performed on 1110 breast cancer patients who were negative for BRCA1, BRCA2, TP53 and PTEN gene mutations and recruited from March 2007 to June 2015 in the Hong Kong Hereditary and High Risk Breast Cancer Program. Four different RECQL pathogenic mutations were identified in six of the 1110 (0.54 %) tested breast cancer patients. The identified mutations include one frame-shift deletion (c.974_977delAAGA), two splicing site mutations (c.394+1G>A, c.867+1G>T) and one nonsense mutation (c.796C>T, p.Gln266Ter). Two of the mutations (c.867+1G>T and p.Gln266Ter) were seen in more than one patients. This study provides the basis for existing of pathogenic RECQL mutations in Southern Chinese breast cancer patients. The significance of rare variants in RECQL gene in the estimation of breast cancer risk warranted further investigation in larger cohort of patients and in other ethnic groups. PMID:27125668

    Importance No consensus exists regarding the definition of “high risk” surgery in older adults. An inclusive and precise definition of high risk surgery may be useful for surgeons, patients, researchers and hospitals. Objectives To develop a list of “high risk” operations. Design 1) Retrospective cohort study; and 2) Modified Delphi procedure. Setting All Pennsylvania acute care hospitals (Pennsylvania Health Care Cost Containment Council [PHC4], 2001–2007) and a nationally-representative sample of U.S. acute care hospitals (Nationwide Inpatient Sample [NIS], HCUP, AHRQ 2001–2006). Patients Admissions 65 and older to PHC4 hospitals and admissions 18 and older to NIS hospitals. Methods We identified ICD-9 CM procedure codes associated with >1% inpatient mortality in PHC4. We used a modified Delphi technique with 5 board certified surgeons to further refine this list by excluding non-operative procedures and operations that were unlikely to be the proximate cause of mortality and were instead a marker of critical illness (e.g., tracheostomy). We then cross-validated this list of ICD-9CM codes in the NIS. Main Outcomes Measures 1) Delphi consensus of at least 4/5 panelists; 2) proportion agreement in the NIS. Results Among 4,739,522 admissions 65 and older in PHC4, 2,569,589 involved a procedure, encompassing 2,853 unique procedures. Of 1,130 procedures associated with a crude inpatient mortality of at least 1%, 264 achieved consensus as high risk operations by Delphi. The observed inpatient mortality in the NIS was ≥ 1% for 227/264 (86%) of the procedures in patients age 65 and older. The pooled inpatient mortality rate for these identified high risk procedures performed on patients age ≥65 was double the inpatient mortality for correspondingly identified high risk operations for patients less than 65 (6% vs. 3%). Conclusions We developed a list of procedure codes that can be used to identify “high risk” surgical procedures in claims data. This

    Introduction: Deep venous thrombosis (DVT) is thought to be less common in Asians than in Caucasian population. The incidence of DVT in high-risk groups, especially the neurosurgical (NS) patients, has not been well studied. This leaves no firm basis for the start of early prophylactic anticoagulation within first 5 postoperative days in Indian NS patients. This is a prospective observational study to determine the early occurrence of DVT in the NS patients. Patients and Methods: We screened 137 consecutive high-risk NS patients based on inclusion and exclusion criteria. The femoral veins were screened using Doppler ultrasound on day 1, 3, and 5 of admission into the NS Intensive Care Unit (ICU) at tertiary center from South India. Results: Among 2887 admissions to NICU 147 patients met inclusion criteria. One hundred thirty seven were screened for DVT. There was a 4.3% (6/137) incidence of DVT with none of the six patients having signs or symptoms of pulmonary embolism. Among the risk factors studied, there was a significant association with femoral catheterization and a probable association with weakness/paraparesis/paraplegia. The mortality in the study group was 10.8% with none attributable to DVT or pulmonary embolism. Conclusion: There is a low incidence of DVT among the high risk neurosurgical population evaluated within the first 5 days of admission to NICU, limiting the need for early chemical thrombo-prophylaxis in these patients. With strict protocols for mechanical prophylaxis with passive leg exercise, early mobilization and serial femoral Doppler screening, heparin anticoagulation can be restricted within the first 5 days of ICU admission in high risk patients.

    Between 2005 and 2007, 14 patients who had severe scoliosis in Duchenne muscular dystrophy (DMD) and a poor forced vital capacity (FVC) of <30% at admission underwent scoliosis surgery. FVC on admission was 21.6% (range, 16-27%). The patients were given respiratory muscle training using a pulmonary trainer (Threshold IMT, Philips Respironics, Inc.) for six weeks before operation. FVC increased to 26.2% (range, 22-31%) the day before operation. The mean preoperative scoliosis was 98 degrees (range, 81 degrees-130 degrees). All patients underwent posterior fusion and all-screw construction and were extubated on the operative day. No patients developed any respiratory complications. The postoperative scoliosis was 34 degrees (range, 20 degrees-40 degrees) (65%). FVC remained stable at six weeks after operation. FVC decreased to 19.8% (range, 16-25%) and the mean scoliosis was 35 degrees (range, 23 degrees-40 degrees) (64%) at two years after operation. DMD patients with severe scoliosis and FVC considered too low to permit reasonable surgical risk could undergo surgery and could benefit from surgery. PMID:19340426

    Thoracic paravertebral block is the technique of injecting local anesthetic adjacent to the thoracic vertebra close to where the spinal nerves emerge from the intervertebral foramina. It is effective in treating acute and chronic pain of unilateral origin from the chest and abdomen. This technique causes pain relief with pulmonary function preservation and great hemodynamic stability. 66 year old woman (156 cm, 80 kg, BMI 32) with chronic right heart failure, hypertension and obesity, on chronic oxygen therapy was presented for elective mastectomy due to breast cancer. She suffered from severe COPD and also bullous emphysema. FVC 1.59 l; FEV1 0.55 l; FEV1%FVC 34.6. The paravertebral block was performed using the multi-shot percutaneous technique with additional light general anesthesia. For confirmation, of proper analgesia range, control of temperature changes, using FLIR i7 infrared camera, was performed. Control photos were made 20 min after the blockade and then 10 min later. Infrared photo showed rise of temperature reading in every marked region. There were no hemodynamic and pulmonary complications postoperatively. Paravertebral block in combination with sedation creates excellent conditions for breast surgery procedures. Additional temperature changes monitoring performed with infrared camera may confirm proper range of analgesia needed to perform surgery. Great cardiovascular stability and very good pulmonary function preservation make this method excellent for high risk patients. Low complication rate is additional advantage. In our opinion this method is recommendable. PMID:25059839

    Purpose. We wanted to demonstrate the utility of the radionuclide salivagram in assessing children whose underlying medical problems suggest that aspiration of oral contents is a factor contributing to otherwise unexplained lung disease or recurrent pneumonias. Materials and methods. Following sublingual administration of 300 μCi (11.1 MBq) of technetium-99m sulfur colloid in a drop of saline, serial images were obtained for 60 min and evaluated for entrance of tracer into the major airways and lung parenchyma. Thirty-four studies were performed on 31 patients (age: 3 weeks - 16.7 years, mean 5.5 years) with recurrent pneumonias or unexplained lung disease. All had medical conditions, most frequently neurological, predisposing to aspiration. Results. Pulmonary aspiration was detected in eight patients. All positive studies demonstrated aspirated tracer distal to the tracheal bifurcation, either in bronchi or in bronchi and lung parenchyma. Aspiration was bilateral in six cases. Clearance of aspirated tracer was noted in one patient. Conclusion. The salivagram is an effective tool for demonstrating aspiration of oral contents and the level to which aspirated fluid penetrates the tracheobronchial tree. Additionally, by allowing for the evaluation of clearance of aspirated tracer, the salivagram may provide information on the status of airway-protective mechanisms. PMID:8577521

    Identifying patients at high risk of breast cancer recurrence has important implications not only for enabling the ability to provide accurate information to patients but also the potential to improve patient outcomes. Patients at high recurrence risk can be offered appropriate treatment to improve the overall survival. However, the major challenge is identifying patients with early-stage breast cancer at lower risk who may be spared potentially toxic therapy. The successful integration of molecular assays into clinical practice may address the problem of overtreatment and improve overall patient outcomes. PMID:26504408

    The influenza season affects not only the people afflicted with influenza, but the healthcare system as a whole. An estimated dollar 12 billion is the annual cost to care for these patients. An existing problem is that although there is an immunization for influenza, many patients at high risk are not immunized. This article will describe an innovative program of a large Midwest suburban hospital to immunize patients at high risk. PMID:16398063

    Background: Conservative treatment was recommended as the treatment of choice in perforated acute peptic ulcer. Here, we adjunct percutaneous peritoneal drainage with nonoperative conservative treatment in high risk elderly patients with perforated duodenal ulcer. Aim: The work was to study the efficacy of percutaneous peritoneal drainage under local anesthesia supported by conservative measures in high risk elderly patients, according to the American Society of Anesthesiologists grading, with perforated duodenal ulcer. Patients and Methods: Twenty four high risk patients with age >65 years having associated medical illness with evidence of perforated duodenal ulcer. Results: The overall morbidity and mortality were comparable with those treated by conservative measures alone. Conclusion: In high risk patients with perforated peptic ulcer and established peritonitis, percutaneous peritoneal drainage under local anesthesia seems to be effective with least operative trauma and mortality rate.

    Background: Pharmacist interventions have been shown to have an impact on reducing readmission rates, however further research is necessary to target resources to high-risk populations and determine the most effective bundle of interventions. Objective: To evaluate the effect of a pharmacist-bundled intervention on 30-day readmission rates for high-risk patients with pneumonia. Methods: A pilot study with a historical control conducted at a community, teaching-affiliated medical center. Up to 65 selected subjects were included if they had pneumonia and any of the following high-risk criteria: admission within 6 months, at least 5 scheduled home medications, chronic obstructive pulmonary disease (COPD), or heart failure. A retrospective chart review was conducted to compile the historical control group that received usual care between June and November 2013. Patients admitted from December 2013 through March 2014 were reviewed to receive a bundled intervention. The primary outcome was 30-day readmission rates. Risk factors and reasons for readmission, pharmacist clinical interventions, and the time interval between discharge and readmission were also evaluated. Results: A trend toward a reduced 30-day readmission rate was observed in the intervention group (n = 43) compared to those who received usual care (n = 65) (27.9% vs 40.0%; relative risk [RR], 0.6977; 95% CI, 0.3965–1.2278; P = .2119). The most commonly identified high-risk inclusion criteria were having at least 5 scheduled home medications and COPD. The time interval between discharge and readmission did not considerably differ between groups (10.8 vs 10.6 days). Conclusions: The pharmacist-bundled intervention was associated with a reduced 30-day readmission rate for high-risk patients with pneumonia. PMID:26823619

    An increased number of sensitized patients await kidney transplantation (KTx). Sensitization has a major impact on patient mortality and morbidity due to prolonged waiting time and may preclude live donor transplantation. However, recent reports have shown that KTx can be performed successfully using novel immunosuppressive protocols. This study presents our experience with patients displaying donor-specific antibody (DSA) (+). We enrolled 5 lymphocyte cross-match (LCM) negative (complement-dependent cytotoxicity) and panel-reactive antibody (PRA) plus DSA-positive patients mean fluorescein intensity [MFI] > 1000) who underwent living kidney donor procedures. All subjects were females and their mean age was 36.7 years. In our protocol, we started mycophenolate mofetil (2 g/d), tacrolimus (0.01 mg/kg) and prednisolone (0.5 mg/kg) on day -6. We performed 2 sessions of total plasma exchange (TPE) with albumin replacement and administered 2 doses of IVIG (5 g/d). On day -1, we added rituximab (200 mg). On the operation day and on day +4, the patients received doses of basiliximab. Serum samples were taken on days -6, 0, and 30 as well as at 1 year after transplantation. All patients displayed immediate graft function. Mean basal DSA titer was 5624 MFI. After desensitization, the MFI titers decreased at the time of transplantation to 2753 MFI, and were 2564 MFI at the 1st month and 802 MFI at 1st year. Three patients experienced acute rejection episodes (60%). After treatment for rejection, the average follow-up was 17 months and last creatinine levels were 0.6-0.8 mg/dL (minimum-maximum). In conclusion, KTx can be succesfully performed in sensitized patients displaying DSA. However, there seems to be a greater acute rejection risk. There is no consensus regarding adequate doses of IVIG or plasmapheresis treatments; furthermore, more studies are needed to clarify the safe MFI titer of the DSA. PMID:23622587

    Little information is available about survival of high-risk pediatric neuroblastoma patients in developing countries. We aimed to assess survival among high-risk pediatric neuroblastoma patients in La Plata, Argentina. Individuals eligible for our cohort were aged <20 yr when diagnosed with high-risk neuroblastoma and received cancer-directed therapy including stem cell transplantation at Hospital de Niños Sor Maria Ludovica between February 1999 and February 2015. We estimated overall survival probabilities using an extended Kaplan-Meier approach. Our study population comprised 39 high-risk neuroblastoma patients, of whom 39% were aged >4 yr at diagnosis, 54% were male, and 62% had adrenal neuroblastoma. We observed 18 deaths, and the median survival time of our study population was 1.7 yr. The five-yr overall survival probability was 24% (95% CL: 10%, 41%). In contrast, five-yr survival of high-risk neuroblastoma patients ranges between 23% and 76% in developed countries. Survival among high-risk neuroblastoma patients is generally poor regardless of geographic location, but our results illustrate dramatically worse survival for patients in a developing country. We speculate that the observed survival differences could be attenuated or eliminated with improvements in treatment and supportive care, but addressing these issues will require creative solutions because of resource limitations.

    We have developed a tele-medicine system to monitor the airway status at home for patients with poorly controlled asthma, whereby a nurse provides instructions to individuals via the telephone to help them manage exacerbation under the supervision of their physicians. We examined the effectiveness of this system with a randomized control study. Patients with high hospitalization risk were enrolled in the study by screening patients for those with multiple previous emergency room visits and randomly assigned to either the tele-medicine or control group. After six months of participation in the program, the number of emergency room visits decreased significantly and the activities of daily living were improved in the tele-medicine group. Most of the patients in the tele-medicine group were able to continue measuring and transmitting peak expiratory flow (PEF) value successfully, and at six months had noticed an improvement in PEF. We therefore conclude that the system effectively contributes to the management of poorly controlled asthma. In addition, further consideration suggests that the reduction of emergency room visits may lead to reduction in hospitalization since we found a good correlation between number of emergency room visits and hospitalization from the studies published previously.

    Bariatric surgery is the most effective way to improve comorbidities related to obesity. Since the introduction of minimally invasive laparoscopic surgery in the bariatric surgery techniques, the number of procedures has increased substantially; advances in techniques and the transition from open to minimally invasive procedures have decreased morbidity and mortality. Multidisciplinary teams in charge of the operative planning, surgical act, and postoperative recovery are determinant in the success of the management of high-risk bariatric patients; careful identification and preoperative management of these higher-risk patients is crucial in decreasing complications after weight loss surgery.

    Low bone mass is a major determinant of bone fragility. With respect to hip fracture risk however, there is limited contribution of BMD to the exponential age-related increase in hip fracture incidence. Large prospective studies have identified a number of additional risk factors for hip fractures independent of bone density. These can be classified as skeletal factors and fall-related factors. Body height and hip axis length are positively correlated with fracture risk. Neuromuscular impairment with low gait speed, difficulty in doing a tandem walk, lower limb dysfunction, body sway or inability to rise from a chair without using one's arms predict future fracture risk. According to the concept of evidence-based medicine (EBM) preventive strategies are now available. Supplementation with calcium and vitamin D restores bone quality through suppression of secondary hyperparathyroidism and decreases the risk of falling through improvement of neuromuscular co-ordination and body sway. Treatment with the bisphosphonates alendronate and risedronate increase bone strength and result in a significant reduction of vertebral as well as non-vertebral fractures. Hip protectors absorb energy during a fall and reduce hip fracture risk by 56%. Risk factor based patient selection may improve the cost-effectiveness of therapy. PMID:10996933

    It has been suggested for many years that regional anaesthesia is advantageous in high-risk patients, either as the sole anaesthetic or in combination with general anaesthesia. Regional techniques are safe and even more so when guided by ultrasound. In the high-risk patient population, ultrasound-guided regional anaesthesia (UGRA) can help decrease risk of perioperative morbidity and improve short-term as well as long-term outcomes, particularly in the orthopaedic, vascular, oncologic and chronic pain patient populations. Nevertheless, complications do still occur and benefits of a specific regional nerve blockade need to be weighed against potential risks on an individual basis. The emergence of reasonably priced, easy-to-use ultrasound machines facilitates regional anaesthesia, and this kind of anaesthesia may become the standard of care in high-risk patients.

    Identifying 'high risk' (> 5% mortality score) emergency general surgical patients early, allows appropriate perioperative care to be allocated by securing critical care beds and ensuring the presence of senior surgeons and senior anesthetists intraoperatively. Scoring systems can be used to predict perioperative risk and coordinate resources perioperatively. Currently it is unclear which estimate of risk correlates with current resource deployment. A retrospective study was undertaken assessing the relationship between deployment of perioperative resources: senior surgeon, senior anesthetist and critical care bed. The study concluded that almost all high risk patients with high POSSUM mortality and morbidity scores had a consultant senior surgeon present intraoperatively. Critically unwell patients with higher operative severity and perioperative morbidity scores received higher care (HDU/ICU) beds postoperatively, ensuring that they received appropriate care if their condition deteriorated. Therefore POSSUM scoring should be used perioperatively in emergency cases to coordinate appropriate perioperative care for high risk general surgical patients. PMID:26901929

    Corneas with severe pathologies have a high risk of rejection when conventionally grafted with human donor tissues. In this early observational study, we grafted bioengineered corneal implants made from recombinant human collagen and synthetic phosphorylcholine polymer into three patients for whom donor cornea transplantation carried a high risk of transplant failure. These patients suffered from corneal ulcers and recurrent erosions preoperatively. The implants provided relief from pain and discomfort, restored corneal integrity by promoting endogenous regeneration of corneal tissues, and improved vision in two of three patients. Such implants could in the future be alternatives to donor corneas for high-risk patients, and therefore, merits further testing in a clinical trial. PMID:25996570

    The role of goal-directed therapy in high-risk cardiac surgical patients has not been determined. This study sought to observe the effect of a postoperative standardised haemodynamic protocol (SHP) on the administration of fluid and vasoactive drugs after high-risk cardiac surgery. This was an interventional pilot study. In 2010 to 2011, the SHP was introduced to the ICU at Wellington Regional Hospital, Wellington, New Zealand, for the perioperative management of patients undergoing high-risk cardiac surgery. A pulmonary artery catheter was inserted in the patients in the study group and fluids and supportive medications were provided in the ICU according to a protocol that targeted a cardiac index ≥ 2 l/min/m², mixed venous oxygen saturation ≥ 60% and a mean arterial pressure of 65 to 75 mmHg. Data from 40 consecutive high-risk cardiac surgical patients assigned to this protocol were compared with a matched cohort of 40 consecutive high-risk cardiac surgical patients receiving 'usual care' in 2009. Baseline characteristics were similar in the two groups. There was no significant difference in the duration of noradrenaline infusion in the SHP cohort compared to historical controls (median [IQR] 18.5 hours [31.63] versus 18 hours [18.3]; P=0.35), despite patients receiving more fluid in their first 12 hours in the ICU (mean 4687 ml [SD ± 2284 ml] versus 1889 ml [SD ± 1344 ml]; P <0.001). The SHP cohort had a higher rate of reintubation (4 in 37 [10.8%] versus 0 in 40 [0%]; P=0.049). The SHP delivered significantly more fluid, but did not reduce the duration of noradrenaline infusion, compared to usual care. PMID:26310413

    Despite advances in the local treatment of UM, half of patients develop metastases typically to the liver with poor survival. Microscopic complete surgical resection (R0) of liver metastases improves survival in high selected patients. Early identification of high-risk patients might allow detection of asymptomatic metastases, and increase R0 liver surgery rate. From October 2006 to December 2009, we conducted a prospective study to detect early minimal lesions with 6-monthly liver function tests (LFTs) and liver MRI in 100 high-risk patients. High risk was defined by primary tumor clinical or genomic criteria: thickness>8mm or diameter>15 mm, or extra-scleral extension, or monosomy 3 by FISH or aCGH. With a median follow-up of 49 months, the 5-year metastasis-free survival and overall survival were 47 and 33%, respectively. Of the 60 patients who became metastatic, 50 (83%) had exclusive liver metastasis. LFTs screening had no sufficient accurary, but biannual MRI showed high predictive value to detect metastasis and select patients eligible for curative surgery: 25/50 underwent laparotomy and among them, 8/25 (32%) had a R0 surgery. Median survival after metastasis was 14 months, mean survival reached 40 months in the R0 resected population. Six-monthly liver MRI screening is recommended in patients with large tumors or genomic high risk in order to detect early patient candidates to complete resection of liver metastases. PMID:25978872

    Chronic pain patients who show aberrant drug-related behavior often are discontinued from treatment when they are noncompliant with their use of opioids for pain. The purpose of this study was to conduct a randomized trial in patients who were prescribed opioids for noncancer back pain and who showed risk potential for or demonstration of opioid misuse to see if close monitoring and cognitive behavioral substance misuse counseling could increase overall compliance with opioids. Forty-two patients meeting criteria for high-risk for opioid misuse were randomized to either standard control (High-Risk Control; N=21) or experimental compliance treatment consisting of monthly urine screens, compliance checklists, and individual and group motivational counseling (High-Risk Experimental; N=21). Twenty patients who met criteria indicating low potential for misuse were recruited to a low-risk control group (Low-Risk Control). Patients were followed for 6 months and completed pre- and post-study questionnaires and monthly electronic diaries. Outcomes consisted of the percent with a positive Drug Misuse Index (DMI), which was a composite score of self-reported drug misuse (Prescription Drug Use Questionnaire), physician-reported abuse behavior (Addiction Behavior Checklist), and abnormal urine toxicology results. Significant differences were found between groups with 73.7% of the High-Risk Control patients demonstrating positive scores on the DMI compared with 26.3% from the High-Risk Experimental group and 25.0% from the Low-Risk Controls (p<0.05). The results of this study demonstrate support for the benefits of a brief behavioral intervention in the management of opioid compliance among chronic back pain patient at high-risk for prescription opioid misuse.

    Summary Background Despite the progress in contemporary medicine comprising diagnostic and therapeutic methods, lung cancer is still one of the biggest health concerns in many countries of the world. The main purpose of the study was to evaluate the detection rate of pulmonary nodules and lung cancer in the initial, helical low-dose CT of the chest as well as the analysis of the relationship between the size and the histopathological character of the detected nodules. Material/Methods We retrospectively evaluated 1999 initial, consecutive results of the CT examinations performed within the framework of early lung cancer detection program initiated in Szczecin. The project enrolled persons of both sexes, aged 55–65 years, with at least 20 pack-years of cigarette smoking or current smokers. The analysis included assessment of the number of positive results and the evaluation of the detected nodules in relationship to their size. All of the nodules were classified into I of VI groups and subsequently compared with histopathological type of the neoplastic and nonneoplastic pulmonary lesions. Results Pulmonary nodules were detected in 921 (46%) subjects. What is more, malignant lesions as well as lung cancer were significantly, more frequently discovered in the group of asymptomatic nodules of the largest dimension exceeding 15 mm. Conclusions The initial, low-dose helical CT of the lungs performed in high risk individuals enables detection of appreciable number of indeterminate pulmonary nodules. In most of the asymptomatic patients with histopathologically proven pulmonary nodules greater than 15 mm, the mentioned lesions are malignant, what warrants further, intensified diagnostics.

    The prognosis is very poor in patients with acute respiratory failure (ARF) due to active pulmonary tuberculosis, especially in those who necessitate mechanical ventilation. The underlining factors of ARF are low nutrition, old age and severity because of patient's delay and doctor's delay. So, management consists of two parts, one, early patient detection considering of tuberculosis and early treatment, the other, focused control to high risk groups. Patients with chronic respiratory failure due to pulmonary tuberculosis sequelae have long insidious period and mainly restrictive, sometimes mixed pulmonary dysfunction. Hypercapnea, pulmonary hypertension and respiratory disorder during sleep are seen in high percentage in them. In acute on chronic failure the principles of therapy are treatment of precipitating factors such as respiratory infection or congestive heart failure, controlled (low flow) oxygen therapy, bronchial hygiene and maintaining adequate pulmonary and circulatory condition. In chronic stage patient education is very important. Management of chronic stage is constructed of nutrition control, long-term oxygen therapy, pharmacological therapy, pulmonary rehabilitation including controlled breathing technique, physical chest therapy and exercise training. Noninvasive positive pressure ventilation is effective on improvement of prognosis in chronic respiratory failure, and on treatment in acute on chronic failure. PMID:12664448

    2015-01-01

    Background: The safety of pharmacotherapy in atrial fibrillation (AF) is compounded by a trilogy of risks old age, high-risk medications (e.g., antithrombotics, antiarrhythmics), polypharmacy due to multiple patient comorbidities. However, to date, scarce study has investigated the use of polypharmacy (including potentially inappropriate medication (PIM)) in AF patients, and how this may contribute to their overall risk of medication misadventure. Objectives: To review the extent of polypharmacy and PIM use in older patients (65 years or older) with AF. Methods: Information was extracted from a database characterising a cohort of older AF patients treated in general practice in New South Wales, Australia. Patient characteristics, number and types of drugs, the degree of PIM use were recorded. The predictors for the use of polypharmacy in older AF patients were identified. Results: Overall, 367 patients (mean age 77.8 years) were reviewed, among which 94.8% used 5 medications or more and over half used 10 medications or more. Cardiovascular agents were most commonly used (98.9%), followed by antithrombotics (90.7%). Among agents deemed PIMs, digoxin (30.2%) was the most frequently used, followed by benzodiazepines (19.6%), and sotalol (9.8%). AF patients using polypharmacy were more likely to have low bleeding risk (OR=10.97), representing those patients in whom high-risk antithrombotics are mostly indicated. Patients with major-polypharmacy (5-9 medications) are more likely to have obstructive pulmonary diseases (OR=2.32), upper gastrointestinal diseases (OR=2.02) and poor physical function (OR=1.04), but less likely to have cognitive impairment (OR=0.27). Conclusion: Polypharmacy affects oldest AF patients, comprising medications that are indicated for AF, yet regarded as PIMs. Patients with lower risk of bleeding, obstructive pulmonary diseases, upper gastrointestinal diseases and poor physical function are also at higher risk of using higher number of

Multivariate analysis found that age (60-80 years and ≥80 years versus <60 years, relative risk 2.99, 95% CI 2.31-3.89), lower body mass index (25-30 kg·m(-2) versus ≤20 kg·m(-2), relative risk 0.80, 95% CI 0.66-0.97), lung cancer (relative risk 2.08, 95% CI 1.43-3.01), cardiovascular comorbidity (relative risk 1.35, 95% CI 1.16-1.58), previous hospital admissions for acute exacerbation of COPD (four or more versus none, relative risk 1.91, 95% CI 1.44-2.53), use of accessory respiratory muscles (relative risk 1.19, 95% CI 1.01-1.40) or lower-limb oedema (relative risk 1.74, 95% CI (1.44-2.12)) at admission and treatment by long-term oxygen therapy at discharge (relative risk 2.09, 95% CI 1.79-2.45) were independent risk factors of death. Mortality rate during the 4 years following hospital admission for acute exacerbation of COPD was high (45%). Simple clinical information relating to respiratory and general status can help in identifying high-risk patients and targeting more intensive follow-up and care. Interestingly, cardiovascular comorbidities and past hospitalisations for acute exacerbation of COPD, but not forced expiratory volume in 1 s, independently predicted the risk of death.

    The presence of certain high-risk cytogenetic abnormalities, such as translocations (4;14) and (14;16) and deletion (17p), are known to have a negative impact on survival in multiple myeloma (MM). The phase 3 study ASPIRE (N = 792) demonstrated that progression-free survival (PFS) was significantly improved with carfilzomib, lenalidomide, and dexamethasone (KRd), compared with lenalidomide and dexamethasone (Rd) in relapsed MM. This preplanned subgroup analysis of ASPIRE was conducted to evaluate KRd vs Rd by baseline cytogenetics according to fluorescence in situ hybridization. Of 417 patients with known cytogenetic risk status, 100 patients (24%) were categorized with high-risk cytogenetics (KRd, n = 48; Rd, n = 52) and 317 (76%) were categorized with standard-risk cytogenetics (KRd, n = 147; Rd, n = 170). For patients with high-risk cytogenetics, treatment with KRd resulted in a median PFS of 23.1 months, a 9-month improvement relative to treatment with Rd. For patients with standard-risk cytogenetics, treatment with KRd led to a 10-month improvement in median PFS vs Rd. The overall response rates for KRd vs Rd were 79.2% vs 59.6% (high-risk cytogenetics) and 91.2% vs 73.5% (standard-risk cytogenetics); approximately fivefold as many patients with high- or standard-risk cytogenetics achieved a complete response or better with KRd vs Rd (29.2% vs 5.8% and 38.1% vs 6.5%, respectively). KRd improved but did not abrogate the poor prognosis associated with high-risk cytogenetics. This regimen had a favorable benefit-risk profile in patients with relapsed MM, irrespective of cytogenetic risk status, and should be considered a standard of care in these patients. This trial was registered at www.clinicaltrials.gov as #NCT01080391. PMID:27439911

    2016-01-01

    Existing epidemiologic and clinical trial data suggest that the blood pressure in patients with hypertension at high risk for cardiovascular events because of coronary artery disease, diabetes mellitus, chronic kidney disease, stroke, or heart failure should be reduced to <140/90 mm Hg in patients younger than 80 years and the systolic blood pressure be reduced to 140-145 mm Hg if tolerated in patients aged 80 years and older. Studies from patients with coronary artery disease, diabetes mellitus, chronic kidney disease, stroke, and heart failure will be discussed that support a blood pressure goal of <140/90 mm Hg in patients younger than 80 years at high risk for cardiovascular events.

    2011-01-01

    Introduction Several studies have demonstrated that perioperative hemodynamic optimization has the ability to improve postoperative outcome in high-risk surgical patients. All of these studies aimed at optimizing cardiac output and/or oxygen delivery in the perioperative period. We conducted a survey with the American Society of Anesthesiologists (ASA) and the European Society of Anaesthesiology (ESA) to assess current hemodynamic management practices in patients undergoing high-risk surgery in Europe and in the United States. Methods A survey including 33 specific questions was emailed to 2,500 randomly selected active members of the ASA and to active ESA members. Results Overall, 368 questionnaires were completed, 57.1% from ASA and 42.9% from ESA members. Cardiac output is monitored by only 34% of ASA and ESA respondents (P = 0.49) while central venous pressure is monitored by 73% of ASA respondents and 84% of ESA respondents (P < 0.01). Specifically, the pulmonary artery catheter is being used much more frequently in the US than in Europe in the setup of high-risk surgery (85.1% vs. 55.3% respectively, P < 0.001). Clinical experience, blood pressure, central venous pressure, and urine output are the most widely indicators of volume expansion. Finally, 86.5% of ASA respondents and 98.1% of ESA respondents believe that their current hemodynamic management could be improved. Conclusions In conclusion, these results point to a considerable gap between the accumulating evidence about the benefits of perioperative hemodynamic optimization and the available technologies that may facilitate its clinical implementation, and clinical practices in both Europe and the United States.

    Cholecystostomy is frequently performed to obtain control of sepsis in high risk patients with acute cholecystitis. Retained stones in the gallbladder may cause future clinical problems. We present two patients with cholecystostomy tubes managed non-operatively. A review of other reported methods for stone extraction or destruction is also presented. Knowledge of safe and effective techniques for removal of these stones, using minimally invasive techniques is useful to the general surgeon.

    An increase in elderly patients and severity of illness rates means greater use of nasogastric feeding tubes for both high-risk acutely ill and chronically ill patients. When the QA screening process at Booth Memorial Medical Center revealed a certain percentage of complications with small bore, weight-tipped feeding tubes inserted through the nares, a multidisciplinary peer review committee (MPRC) was formed to review the enteral nutrition program. After a literature review to determine possible complications, the MPRC identified lung perforations due to tube misplacement, tube feeding aspiration into the lungs leading to possible aspiration pneumonia, and an internal tip separation from the tube product failure. Unconscious incubated patients on ventilators were shown as at high risk for feeding tube misplacement in an initial MPRC patient study. A second study evaluated several different feeding tube products in the medical, respiratory and surgical ICU. The MPRC established a credentialing process for physician assistants, interns and residents in feeding tube placement. The MPRC proceedings were presented to the hospital-wide QA committee for review, endorsement and recommendations on all policy and procedure changes. The conclusions were that a more concerted effort must be made to improve medical management and encourage ongoing education in the administration of enteral feedings to high-risk patients.

    Ten consecutive children with high risk leukemia have been submitted to UCB transplant from unrelated HLA mismatched donors. All patients received an identical regimen for conditioning and GVHD prophylaxis. The median dose of viable nucleated cells infused was 2.6 x 10(6)/kg b.w. Among the nine patients evaluable for engraftment the hematopoiesis was of full donor origin in six patients and autologous in three. At a median follow-up of 9 months, six of nine (67%) patients are alive in CR. PMID:9715896

    Patients with frequent hospitalizations generate a disproportionate share of hospital visits and costs. Accurate determination of patients who might benefit from interventions is challenging: most patients with frequent admissions in 1 year would not continue to have them in the next. Our objective was to employ a validated regression algorithm to case-find Medicaid patients at high-risk for hospitalization in the next 12 months and identify intervention-amenable characteristics to reduce hospitalization risk. We obtained encounter data for 36,457 Medicaid patients with any visit to an urban public hospital from 2001 to 2006 and generated an algorithm-based score for hospitalization risk in the subsequent 12 months for each patient (0 = lowest, 100 = highest). To determine medical and social contributors to the current admission, we conducted in-depth interviews with high-risk hospitalized patients (scores >50) and analyzed associated Medicaid claims data. An algorithm-based risk score >50 was attained in 2,618 (7.2%) patients. The algorithm's positive predictive value was equal to 0.67. During the study period, 139 high-risk patients were admitted: 60 met inclusion criteria and 50 were interviewed. Fifty-six percent cited the Emergency Department as their usual source of care or had none. Sixty-eight percent had >1 chronic medical conditions, and 42% were admitted for conditions related to substance use. Sixty percent were homeless or precariously housed. Mean Medicaid expenditures for the interviewed patients were $39,188 and $84,040 per patient for the years immediately prior to and following study participation, respectively. Findings including high rates of substance use, homelessness, social isolation, and lack of a medical home will inform the design of interventions to improve community-based care and reduce hospitalizations and associated costs.

  12. Intensified Surveillance for Early Detection of Breast Cancer in High-Risk Patients

    2015-01-01

    Summary Efforts for early detection of breast cancer play an important role in the care of high-risk women. This will include both women with a pathological mutation in one of the known breast cancer susceptibility genes as well as women with a high breast cancer risk based on family history only. Due to the much higher incidence of breast cancer in premenopausal women with a genetic predisposition or a familial background, to be most effective, imaging-based breast surveillance should start at an age as early as 25–30 years. There is now ample evidence that magnetic resonance imaging (MRI) is by far the most sensitive imaging modality in young high-risk women. With high-risk multimodality screening at least 30% of breast cancers will be detected primarily by MRI and would have been missed at regular screening without MRI. Therefore, most high-risk breast surveillance programs now offer annual MRI to eligible high-risk women from age 25 to 30, usually supplemented by regular mammography starting at least from age 40. The inclusion of clinical breast exam (CBE) and/or ultrasound in the high-risk surveillance has little impact on the detection of additional cancers, but may improve compliance and reduce unnecessary callbacks for nonspecific findings on MRI. To reduce advanced stage interval cancers, especially in BRCA1/2 mutation carriers, some programs offer additional semiannual CBE and/or ultrasound or alternate MRI and mammography every 6 months. How long regular MRI should be continued in high-risk women is a matter of considerable debate. It appears feasible that MRI can safely be discontinued even in BRCA1/2 mutation carriers between the age of 60 and 70, especially if mammographic breast density is low. Even though several cohort studies have now demonstrated a very favorable stage distribution of breast cancers found in women undergoing high-risk surveillance with MRI, data on long-term survival and mortality in these patients is still rare.

    Purpose: Standard therapies for high-risk prostate cancer have resulted in suboptimal outcomes with both local and distant failures. Prostate-specific antigen (PSA) and distant metastases rates as well as biopsy outcomes are reported after a regimen of trimodality therapy with hormonal, radioactive seed, and external beam radiation therapy to demonstrate how patterns of failure are changed when local control is optimized. Methods and Materials: From 1994 to 2003, a total of 360 patients with high-risk prostate cancer were treated with trimodality therapy. Patients were defined as being at high risk if they possessed at least one of the following high-risk features: Gleason score 8 to 10, PSA >20, clinical stage t2c to t3, or two or more intermediate risk features: Gleason score 7, PSA >10 to 20, or stage t2b. Patients were followed for a median of 4.25 years (range, 2 to 10 years). Results: The actuarial 7-year freedom from PSA failure and freedom from distant metastases (FFDM) rates were 83% and 89% respectively. Patients (n = 51) developing PSA failure exhibited aggressive disease behavior with short PSA doubling times (median, 5 months) and a 7-year freedom from distant metastases rate of 48%. Local control was high. The last posttreatment biopsy results were negative in 97% of cases (68 of 70 patients). In multivariate analysis, only PSA >20 predicted biochemical failure (p = 0.04), and only seminal vesicle status predicted developing distant failure (p = 0.01). Conclusions: Trimodality therapy results in excellent local control that alters patterns of failure, resulting in similar actuarial biochemical and distant failure rates. Most failures appear to be distant and exhibit biologically aggressive behavior.

    Short-term and midterm clinical outcomes after endovascular repair of abdominal aortic aneurysms (AAAs) have been well documented. Evaluation of longer term outcomes is now possible. Here we describe our initial 100 high-risk patients treated with endovascular aneurysm repair (EVAR), all with a minimum of 5 years of follow-up. A retrospective review of prospectively recorded data in a departmental database was undertaken for the first 100 consecutive EVAR patients with a minimum of 5 years (range, 60-105 months) of follow-up performed between December 1997 and June 2001. Information was obtained from surgical follow-up visits and family doctors' offices. Endovascular repair of AAA in high-risk patients can be achieved with acceptably low postoperative mortality and morbidity. Longer term results in this high-risk cohort suggest that EVAR is effective in preventing aneurysm-related deaths at 5 years and beyond. All late mortalities were due to patients' comorbid diseases.

    Purpose: To determine whether concurrent androgen deprivation therapy (ADT) during salvage radiotherapy (RT) improves prostate cancer treatment outcomes. Methods and Materials: A total of 630 postprostatectomy patients were retrospectively identified who were treated with three-dimensional conformal RT. Of these, 441 were found to be treated for salvage indications. Biochemical failure was defined as prostate-specific antigen (PSA) of 0.2 ng/mL or greater above nadir with another PSA increase or the initiation of salvage ADT. Progression-free survival (PFS) was defined as the absence of biochemical failure, continued PSA rise despite salvage therapy, initiation of systemic therapy, clinical progression, or distant failure. Multivariate-adjusted Cox proportional hazards modeling was performed to determine which factors predict PFS. Results: Low-, intermediate-, and high-risk patients made up 10%, 24%, and 66% of patients, respectively. The mean RT dose was 68 Gy. Twenty-four percent of patients received concurrent ADT (cADT). Regional pelvic nodes were treated in 16% of patients. With a median follow-up of 3 years, the 3-year PFS was 4.0 years for cADT vs. 3.4 years for cADT patients (p = 0.22). Multivariate analysis showed that concurrent ADT (p = 0.05), Gleason score (p < 0.001), and pre-RT PSA (p = 0.03) were independent predictors of PFS. When patients were stratified by risk group, the benefits of cADT (hazard ratio, 0.65; p = 0.046) were significant only for high-risk patients. Conclusions: This retrospective study showed a PFS benefit of concurrent ADT during salvage prostate RT. This benefit was observed only in high-risk patients.

    Patients with chronic renal failure (CRF) due to various mechanisms are prone to significant pulmonary comorbidities. With the improvements in renal replacement therapy (RRT), patients with CRF are now expected to live longer, and thus may develop complications in the lung from these processes. The preferred treatment of CRF is kidney transplantation and patients who are selected to undergo transplant must have a thorough preoperative pulmonary evaluation to assess pulmonary status and to determine risk of postoperative pulmonary complications. A MEDLINE®/PubMed® search was performed to identify all articles outlining the course of pre-surgical pulmonary evaluation with an emphasis on patients with CRF who have been selected for renal transplant. Literature review concluded that in addition to generic pre-surgical evaluation, renal transplant patients must also undergo a full cardiopulmonary and sleep evaluation to investigate possible existing pulmonary pathologies. Presence of any risk factor should then be aggressively managed or treated prior to surgery. PMID:25599047

    We report a case of calcaneal osteomyelitis that was surgically resected from a patient with diabetes and peripheral vascular disease. A 91-year-old male with history of type 2 diabetes, peripheral vascular disease, balloon angioplasty, and recent (2 months ago) stent of the superficial femoral artery presented to the emergency department with a left heel wound infection probed to bone. The patient reported having been on intravenous Zosyn for several months via an outside infectious disease provider for clinical suspicion of osteomyelitis, but noted no improvement. This report includes information regarding the clinical examination and imaging findings, which were used to assess this high-risk patient. Our patient underwent a partial calcanectomy and completed a 6-week course of intravenous antibiotics. The purpose of this case report is to illustrate limb preservation in a high-risk patient with compromised vascular supply who underwent a partial calcanectomy for treatment of calcaneal osteomyelitis. The patient underwent surgical resection of the calcaneus without complications and healed unremarkably with the ability to ambulate while wearing an ankle foot orthosis with a custom shoe. This report was authorized for publication as an educational report to contribute to generalizable knowledge and does not include any patient health information. PMID:27423990

    Twenty-four high-risk Ewing's sarcoma patients were treated on an intensive combined modality protocol including low-dose fractionated total body irradiaiton (TBI) and autologous bone marrow infusion (ABMI). Twenty patients (83%) achieved a complete clinical response to the primary and/or metastatic sites following induction therapy. The median disease-free interval was 18 months, and nine patients remain disease-free with a follow-up of 22 to 72 months. Local failure as a manifestation of initial relapse occurred in only three patients (15%), each having synchronous distant failure. Eight patients failed initially with only distant metastases, usually within 1-2 years following a complete clinical response. Two patterns of granulocyte recovery following consolidative therapy (including TBI and ABMI) were recognized. The time to platelet recovery was different for the groups with early and late granulocyte recovery. Patients with late recovery did not tolerate maintenance chemotherapy. However, there was no difference in disease-free and overall survival, when comparing the groups with early and late granulocyte recovery. It is concluded that these high-risk Ewing's sarcoma patients remain a poor-prognosis group in spite of intensive combined modality therapy including low-dose TBI. The control of microscopic systemic disease remains the major challenge to improving the cure rate. A new combined modality protocol with high-dose 'therapeutic' TBI (800 rad/2 fractions) is being used and the protocol design is outlined.

    Hemodynamic monitoring and optimization improve postoperative outcome during high-risk surgery. However, hemodynamic management practices among Chinese anesthesiologists are largely unknown. This study sought to evaluate the current intraoperative hemodynamic management practices for high-risk surgery patients in China. From September 2010 to November 2011, we surveyed anesthesiologists working in the operating rooms of 265 hospitals representing 28 Chinese provinces. All questionnaires were distributed to department chairs of anesthesiology or practicing anesthesiologists. Once completed, the 29-item questionnaires were collected and analyzed. Two hundred and 10 questionnaires from 265 hospitals in China were collected. We found that 91.4% of anesthesiologists monitored invasive arterial pressure, 82.9% monitored central venous pressure (CVP), 13.3% monitored cardiac output (CO), 10.5% monitored mixed venous saturation, and less than 2% monitored pulse pressure variation (PPV) or systolic pressure variation (SPV) during high-risk surgery. The majority (88%) of anesthesiologists relied on clinical experience as an indicator for volume expansion and more than 80% relied on blood pressure, CVP and urine output. Anesthesiologists in China do not own enough attention on hemodynamic parameters such as PPV, SPV and CO during fluid management in high-risk surgical patients. The lack of CO monitoring may be attributed largely to the limited access to technologies, the cost of the devices and the lack of education on how to use them. There is a need for improving access to these technologies as well as an opportunity to create guidelines and education for hemodynamic optimization in China. PMID:25332709

    Purpose/Objectives: Despite recent improvements in outcomes, 40% of children with high-risk neuroblastoma will experience relapse, facing a guarded prognosis for long-term cure. Whether recurrences are at new sites or sites of original disease may guide decision making during initial therapy. Methods and Materials: Eligible patients were retrospectively identified from institutional databases at first metastatic relapse of high-risk neuroblastoma. Included patients had disease involving metaiodobenzylguanidine (MIBG)-avid metastatic sites at diagnosis and first relapse, achieved a complete or partial response with no more than one residual MIBG-avid site before first relapse, and received no total body irradiation or therapy with {sup 131}I-MIBG before first relapse. Anatomically defined metastatic sites were tracked from diagnosis through first relapse to determine tendency of disease to recur at previously involved versus uninvolved sites and to assess whether this pattern was influenced by site irradiation. Results: Of 159 MIBG-avid metastatic sites identified among 43 patients at first relapse, 131 (82.4%) overlapped anatomically with the set of 525 sites present at diagnosis. This distribution was similar for bone sites, but patterns of relapse were more varied for the smaller subset of soft tissue metastases. Among all metastatic sites at diagnosis in our subsequently relapsed patient cohort, only 3 of 19 irradiated sites (15.8%) recurred as compared with 128 of 506 (25.3%) unirradiated sites. Conclusions: Metastatic bone relapse in neuroblastoma usually occurs at anatomic sites of previous disease. Metastatic sites identified at diagnosis that did not receive radiation during frontline therapy appeared to have a higher risk of involvement at first relapse relative to previously irradiated metastatic sites. These observations support the current paradigm of irradiating metastases that persist after induction chemotherapy in high-risk patients. Furthermore

    Hemodynamic monitoring and care of the patient at high risk for anesthesia require a careful and systematic approach. During preoperative evaluation the patient at increased risk must be identified and correctable problems must be solved. The patient's current medications must be reviewed because they may influence the choice of anesthetic approach and may alter the physiologic response to the stresses commonly associated with anesthesia. In addition to conventional clinical and electrocardiographic monitoring, perioperative hemodynamic monitoring may be desirable for patients at special risk, who are likely to have significant associated medical problems or to undergo complicated surgical procedures. No ideal induction agent exists, and hypotension secondary to peripheral vasodilation or myocardial depression, or both, is a potential problem. Patients with an inordinately high risk may benefit from mechanical circulatory assistance prior to induction of anesthesia. Attention to oxygenation, blood volume replacement and the prevention of hypertensive episodes are particularly important during anesthesia so that optimal cardiac performance is ensured and ischemia avoided. The stresses during emergence from anesthesia contribute to lability of the cardiovascular status and hypoxemia. The period of risk does not conclude with immediate recovery from anesthesia but extends through the postoperative phase. Careful monitoring and attention to the control of pain, prevention of hypotension and hypertension, adequate oxygenation, early mobilization and resumption of the administration of cardiac medications are important factors in a successful outcome.

    In order to obtain an additional graft versus leukemia effect (GVL) and rapid engraftment, donor leukocyte infusion (DLI) was added to unseparated, sex-mismatched allogeneic bone marrow transplantation in two male patients (age 21, 26) affected by high risk hematological malignancies (refractory T-ALL, refractory B-LBL in leukemic phase). Graft versus host disease (GVHD) prophylaxis consisted of methotrexate (MTX) alone. DLI were obtained after G-CSF 16 ug/kg/day sc. A total of 2.36 and 5.8 x 10(6)/kg MNC, 5.4 and 11 x 10(6)/kg CD34+ cells, 1.3 and 1.3 x 10(6)/kg CD3+ lymphocytes, respectively, were infused. Hemopoietic recovery occurred promptly. Complete chimerism was detected by cytogenetic examination. One patient developed an extramedullary relapse that first involved the cranial nerves, and then the testes, soft tissue and skin; the other patient developed central nervous system disease and then bilateral paravertebral masses with progressive paraplegia. Despite complete medullary remission with normal female karyotype, both patients died from extramedullary progression of their disease. Our observation shows that, at least in high risk patients, no additional GVHD or GVL effect was evident after donor leukocyte infusion. Extramedullary relapse was not prevented despite good control of medullary disease. PMID:8641654

    Epilepsy, characterized by the risk of recurrent seizures, is a chronic disease that afflicts about 5% of the world's population. The main dental problems associated with epileptic patients include gingival hyperplasia, minor oral injuries, tooth trauma, and prosthodontic problems, which require the dental treatment. Stress and fear are the most common triggering factors for the epilepsy in dental chair. Therefore, a more appropriate method of treating such epileptic patients may be warranted. Conscious sedation is a technique of providing good anesthesia and analgesia to patients, the main advantage of which is the patient's rapid return to presentation levels. Midazolam used as a sedative agent has anticonvulsant properties. This case report highlights a case requiring multiple dental procedures carried out in a high risk epileptic patient under conscious sedation. PMID:27041847

    New therapeutic agents are warranted in idiopathic membranous nephropathy. Synthetic ACTH may be advantageous with reported remission rates up to 85% and few side effects. We conducted a prospective open label cohort study from 2008 till 2010 (NCT00694863). We prospectively selected patients with idiopathic membranous nephropathy and high risk for progression (defined as βeta-2-microglobulin (β2m) excretion of >500 ng/min). For comparison, we selected matched historical controls treated with cyclophosphamide. The prospectively selected patients received intramuscular injections of synthetic ACTH during 9 months (maximal dose 1 mg twice a week). The primary endpoints concerned the feasibility and incidence of remissions as a primary event. Secondary endpoints included side effects of treatment and the incidence of remissions and relapses at long-term follow-up. Twenty patients (15 men) were included (age 54±14 years, serum creatinine 104 μmol/l [IQR 90–113], urine protein:creatinine ratio 8.7 g/10 mmol creatinine [IQR 4.3–11.1]). Seventeen patients (85%) completed treatment. 97% of injections were administered correctly. Cumulative remission rate was 55% (complete remission in 4 patients, partial remission 7 patients). In a group of historical controls treated with cyclophosphamide and steroids, 19 of 20 patients (95%) developed a remission (complete remission in 13 patients, partial remission in 6 patients) (p<0.01). The main limitation of our study is its small size and the use of a historical control group. We show that treatment with intramuscular injections of synthetic ACTH is feasible. Our data suggest that synthetic ACTH is less effective than cyclophosphamide in inducing a remission in high risk patients with idiopathic membranous nephropathy. The use of synthetic ACTH was also associated with many adverse events. Therefore, we advise against synthetic ACTH as standard treatment in membranous nephropathy.

    Objective Using a national database, we asked whether video-assisted thoracoscopic surgery (VATS) lobectomy is beneficial in high-risk pulmonary patients. Background Single-institution series demonstrated benefit of VATS lobectomy over lobectomy via thoracotomy in poor pulmonary function patients [FEV1 (forced expiratory volume in 1 second) or DLCO (diffusion capacity of the lung to carbon monoxide) <60% predicted]. Methods The STS General Thoracic Database was queried for patients having undergone lobectomy by either thoracotomy or VATS between 2000 and 2010. Postoperative pulmonary complications included those defined by the STS database. Results In the STS database, 12,970 patients underwent lobectomy (thoracotomy, n = 8439; VATS, n = 4531) and met inclusion criteria. The overall rate of pulmonary complications was 21.7% (1832/8439) and 17.8% (806/4531) in patients undergoing lobectomy with thoracotomy and VATS, respectively (P < 0.0001). In a multivariable model of pulmonary complications, thoracotomy approach (OR = 1.25, P < 0.001), decreasing FEV1% predicted (OR = 1.01 per unit, P < 0.001) and DLCO% predicted (OR = 1.01 per unit, P < 0.001), and increasing age (1.02 per year, P < 0.001) independently predicted pulmonary complications. When examining pulmonary complications in patients with FEV1 less than 60% predicted, thoracotomy patients have markedly increased pulmonary complications when compared with VATS patients (P = 0.023). No significant difference is noted with FEV1 more than 60% predicted. Conclusions Poor pulmonary function predicts respiratory complications regardless of approach. Respiratory complications increase at a significantly greater rate in lobectomy patients with poor pulmonary function after thoracotomy compared with VATS. Planned surgical approach should be considered while determining whether a high-risk patient is an appropriate resection candidate. PMID:22868367

    A surgeon, Dr A. Droit, has been following a 97-year-old male with a type IV thoracoabdominal aneurysm, which became symptomatic this morning and is leaking. The patient is frail but active with no important comorbidities. The anatomy demands an open procedure. The patient is a former renowned physician who has been a longtime family friend of Dr Droit-like a grandfather. He presented incoherent with sagging blood pressure. A complicating factor is that Dr D. Rag, the chief anesthesiologist, decided that neither he nor any of his staff would provide anesthesia. Dr Droit knows an anesthesiologist who handles high-risk patients at another hospital in the medical center. The patient has worsened over the last hour, is becoming more unstable, and is unable to respond but his wife wishes to consent for surgery. What should Dr Droit do? PMID:25619578

    The present paper expresses the need to standardize the basic care that should be given to the patients with musculoskeletal inactivity. Starting from the definition of the high risk disuse syndrome category, the body systems' functionality will be determined. It is important to consider the patients' participation in the activities carried out, as well as their feelings regarding their status and the effects it may produce. The nurse should demonstrate her knowledge and abilities to take care of the patients, keeping the integrity of the skin and of the mucous membranes. An exhaustive bibliographic review was made for this paper. The basic care the patients with musculoskeletal inactivity (disuse syndrome) should receive are explained here. PMID:9479176

    The CLAG regimen is highly active in patients with relapsed and/or refractory acute myeloid leukemia (AML). We administered CLAG-based chemotherapy to 20 previously untreated AML patients who were poor candidates for standard induction therapy. Responding patients received further CLAG as post-remission therapy followed by additional therapy that was tailored to their AML subtype. Patients were considered poor candidates for standard therapy due to either cardiac disease, prior chemotherapy for another malignancy, prior myeloproliferative disease, or myelodysplastic syndrome that had progressed after hypomethylator therapy. Overall, thirteen patients had a complete response (CR) to the first cycle of therapy (65%), one patient had a CR without platelet recovery, and 3 patients had a partial response (PR). Two of the patients with PR converted to CR after further therapy. The median duration of response has not been reached; the mean duration of response is 36.8 months (95% CI 28.8-44.8 months). Median overall survival (including deaths from all causes) is 29.0 months (95% CI 18.0-46.0 months). Patients with de novo AML had a CR rate of 90.9% and a median overall survival of 38.5 months. CLAG-based therapy is a well-tolerated, efficacious induction strategy in previously-untreated patients with high risk AML. CLAG-based regimens should be studied in a broader group of newly diagnosed AML patients. PMID:27151544

    Vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/VC%, PEF, MEF25%, MEF50%, MEF75%, TLS, TGV, pulmonary residual volume (PRV), Raw, Rin, Rex, DLCO-SB, DLCO-SS, PaO2, and PaCO2 were determined in 29 patients with disseminated pulmonary tuberculosis. Pulmonary dysfunction was detected in 93.1% of the patients. Changes were found in lung volumes and capacities in 65.5%, impaired bronchial patency and pulmonary gas exchange dysfunction were in 79.3 and 37.9%, respectively. The changes in pulmonary volumes and capacities appeared as increased PRV, decreased VC, FVC, and TLS, decreased and increased TGV; impaired bronchial patency presented as decreased PEF, MEF25%, MEF50%, MEF75%, and FEV1/VC% and increased Raw, Rin, and Rex; pulmonary gas exchange dysfunction manifested itself as reduced DLCO-SS and PaO2 and decreased and increased PaCO2. The observed functional changes varied from slight to significant and pronounced with a preponderance of small disorders, a lower detection rate of significant disorders, and rare detection of very pronounced ones.

    This review highlights the paucity of data that support actively decreasing blood pressures (BP) to a level of less than 130/80 mm Hg. Although the data support a lower cardiovascular (CV) event rate with this lower level of pressure in high-risk CV people, early aggressive intervention to prevent levels from going above this mark prevent development of worsening atherosclerosis. Although no trial will ever prove this concept of prevention, common sense and multiple animal experiments support it. Most patients should have their systolic BP reduced to levels well below 140 mm Hg approaching 130 mm Hg, not 140 mm Hg. PMID:20621249

  12. Pragmatic fluid optimization in high-risk surgery patients: when pragmatism dilutes the benefits.

    PubMed

    Reuter, Daniel A

    2012-01-01

    There is increasing evidence that hemodynamic optimization by fluid loading, particularly when performed in the early phase of surgery, is beneficial in high-risk surgery patients: it leads to a reduction in postoperative complications and even to improved long-term outcome. However, it is also true that goal- directed strategies of fluid optimization focusing on cardiac output optimization have not been applied in the clinical routine of many institutions. Reasons are manifold: disbelief in the level of evidence and on the accuracy and practicability of the required monitoring systems, and economics. The FOCCUS trial examined perioperative fluid optimization with a very basic approach: a standardized volume load with 25 ml/kg crystalloids over 6 hours immediately prior to scheduled surgery in high-risk patients. The hypothesis was that this intervention would lead to a compensation of preoperative fluid deficit caused by overnight fasting, and would result in improved perioperative fluid homeostasis with less postoperative complications and earlier hospital discharge. However, the primary study endpoints did not improve significantly. This observation points towards the facts that: firstly, the differentiation between interstitial fluid deficit caused by fasting and intravascular volume loss due to acute blood loss must be recognized in treatment strategies; secondly, the type of fluid replacement may play an important role; and thirdly, protocolized treatment strategies should also always be tailored to suit the patients' individual needs in every individual clinical situation.

    Objectives: To explore how family members of ICU patients at high risk of dying respond to nursing communication strategies. Background: Family members of ICU patients may face difficult decisions. Nurses are in a position to provide support. Evidence of specific strategies that nurses use to support decision-making and how family members respond to these strategies is lacking. Methods: This is a prospective, qualitative descriptive study involving the family members of ICU patients identified as being at high risk of dying. Results: Family members described five nursing approaches: Demonstrating concern, building rapport, demonstrating professionalism, providing factual information, and supporting decision-making. This study provides evidence that when using these approaches, nurses helped family members to cope; to have hope, confidence, and trust; to prepare for and accept impending death; and to make decisions. Conclusion: Knowledge lays a foundation for interventions targeting the areas important to family members and most likely to improve their ability to make decisions and their well-being.

    Background and objectives AKI in critically ill patients is usually part of multiorgan failure. However, nonrenal organ failure may not always precede AKI and patients without evidence of these organ failures may not be at low risk for AKI. This study examined the risk and outcomes associated with AKI in critically ill patients with and without cardiovascular or respiratory organ failures at presentation to the intensive care unit (ICU). Design, setting, participants, & measurements A large, academic medical center database, with records from July 2000 through October 2008, was used and the authors identified a low-risk cohort as patients without cardiovascular and respiratory organ failures defined as not receiving vasopressor support or mechanical ventilation within the first 24 hours of ICU admission. AKI was defined using Kidney Disease Improving Global Outcomes criteria. The primary end points were moderate to severe AKI (stages 2–3) and risk-adjusted hospital mortality. Results Of 40,152 critically ill patients, 44.9% received neither vasopressors nor mechanical ventilation on ICU day 1. Stages 2–3 AKI occurred less frequently in the low-risk patients versus high-risk patients within 24 hours (14.3% versus 29.1%) and within 1 week (25.7% versus 51.7%) of ICU admission. Patients developing AKI in both risk groups had higher risk of death before hospital discharge. However, the adjusted odds of hospital mortality were greater (odds ratio, 2.99; 95% confidence interval, 2.62 to 3.41) when AKI occurred in low-risk patients compared with those with respiratory or cardiovascular failures (odds ratio, 1.19; 95% confidence interval, 1.09 to 1.3); interaction P<0.001. Conclusions Patients admitted to ICU without respiratory or cardiovascular failure have a substantial likelihood of developing AKI. Although survival for low-risk patients is better than for high-risk patients, the relative increase in mortality associated with AKI is actually greater for low

    Labor and delivery units are often used to provide care for nonlaboring patients requiring intensive medical and nursing care. The utilization of labor beds in this manner, however, can result in a shortage of beds for those patients who are truly in labor. Unfortunately, patient dissatisfaction, use of supplemental staffing, and ill-prepared, overworked nurses can then become the result of this practice. Clearly, an improved, innovative model of providing care for high-risk perinatal patients is needed. The purpose of this article is to describe how one hospital and its interdisciplinary team met the challenge of providing expert care for complex perinatal patients by creating a unique model of patient care delivery, the perinatal special care unit (PSCU). An advanced practice nursing role, the perinatal nurse practitioner (PNNP) was implemented to provide collaborative care for these patients. This article includes a discussion of positive and negative outcomes that occurred after the PSCU became a reality. Overall, housing patients on the PSCU has eliminated inappropriate use of labor and delivery beds and has led to a more satisfying childbearing experience for all involved. PMID:15867684

    We conducted a trial of telemonitoring and telecare for patients with chronic heart failure leaving hospital after being treated for clinical instability. Eighty patients were randomized before hospital discharge to a usual care group (n=40: follow-up at the outpatient clinic) or to an integrated management group (n=40: patients learned to use a handheld PDA and kept in touch daily with the monitoring centre). At enrolment, the groups were similar for all clinical variables. At one-year follow-up, integrated management patients showed better adherence, reduced anxiety and depression, and lower NYHA class and plasma levels of BNP with respect to the usual care patients (e.g. NYHA class 2.1 vs 2.4, P<0.02). Mortality and hospital re-admissions for congestive heart failure were also reduced in integrated management patients (P<0.05). Integrated management was more expensive than usual care, although the cost of adverse events was 42% lower. In heart failure patients at high risk of relapse, the regular acquisition of simple clinical information and the possibility for the patient to contact the clinical staff improved drug titration, produced better psychological status and quality of life, and reduced hospitalizations for heart failure.

    The 'Individualized Therapy for Relapsed Malignancies in Childhood' (INFORM) precision medicine study is a nationwide German program for children with high-risk relapsed/refractory malignancies, which aims to identify therapeutic targets on an individualised basis. In a pilot phase, reported here, we developed the logistical and analytical pipelines necessary for rapid and comprehensive molecular profiling in a clinical setting. Fifty-seven patients from 20 centers were prospectively recruited. Malignancies investigated included sarcomas (n = 25), brain tumours (n = 23), and others (n = 9). Whole-exome, low-coverage whole-genome, and RNA sequencing were complemented with methylation and expression microarray analyses. Alterations were assessed for potential targetability according to a customised prioritisation algorithm and subsequently discussed in an interdisciplinary molecular tumour board. Next-generation sequencing data were generated for 52 patients, with the full analysis possible in 46 of 52. Turnaround time from sample receipt until first report averaged 28 d. Twenty-six patients (50%) harbored a potentially druggable alteration with a prioritisation score of 'intermediate' or higher (level 4 of 7). Common targets included receptor tyrosine kinases, phosphoinositide 3-kinase-mammalian target of rapamycin pathway, mitogen-activated protein kinase pathway, and cell cycle control. Ten patients received a targeted therapy based on these findings, with responses observed in some previously treatment-refractory tumours. Comparative primary relapse analysis revealed substantial tumour evolution as well as one case of unsuspected secondary malignancy, highlighting the importance of re-biopsy at relapse. This study demonstrates the feasibility of comprehensive, real-time molecular profiling for high-risk paediatric cancer patients. This extended proof-of-concept, with examples of treatment consequences, expands upon previous personalised oncology endeavors

    Background Patients with advanced melanoma have a poor outcome. We hypothesize that combination immunotherapy can synergistically activate host immunity to generate an effective treatment for patients with high-risk, resected stage 3, recurrent, refractory, or stage 4 melanoma. Methods We conducted a phase 2 clinical trial of HyperAcute Melanoma (HAM) vaccine (NLG-12036, NewLink Genetics) combined with pegylated interferon (Sylatron, Merck). Trial design consisted of a 12-week regimen with the initial 4 weekly treatments consisting of HAM alone (intradermally) followed by 8 additional treatments of HAM plus Sylatron (subcutaneously, 6 μg/kg). Trial endpoint outcomes include clinical response, overall safety, and correlative findings for observed antitumor effect. Results Our cohort consisted of 25 patients with a median age of 60. Twenty-one patients completed the trial and 4 stopped because of progressive disease (PD). According to the Response Evaluation Criteria in Solid Tumors, of the 16 stage 4 patients, 2 had a complete response (CR), 1 had stable disease, and 4 had no evidence of disease (NED) after resection. For stage 2/3 patients, 3 of 9 remained NED, and the 1 stage 2C patient had slow PD with a single site resected and is currently NED. The median overall survival time was 29 months, with 60% of the patients surviving for >1 year. Of the 25 patients, 12 (48%) are still alive. All evaluable patients (21/21) seroconverted, developing autoimmune antibodies. Four of 25 patients developed vitiligo, correlating with 2 CR patients and 2 NED patients. Conclusion Combination immunotherapy with HAM plus Sylatron shows clinical efficacy with tumor regression and concomitant immune activation. Optimization of dosing schedules and therapeutic efficacy should be further explored to enhance the benefit of this promising immunotherapeutic approach. PMID:24940124

    We evaluated the feasibility and the patient acceptability of integrating a kiosk into routine emergency department (ED) practice for offering HIV testing. The work was conducted in four phases: phase 1 was a baseline, in which external testing staff offered testing at the bedside; phase 2 was a pilot assessment of a prototype kiosk; phase 3 was a pilot implementation and phase 4 was the full implementation with automated login. Feasibility was assessed by the proportion of offering HIV tests, acceptance, completion and result reporting. During the study period, the number of ED patients and eligible patients for screening were similar in the three main phases. However, the number and proportion of patients offered testing of those eligible for screening increased significantly from phase 1 (32%) to phase 3 (37%) and phase 4 (40%). There were slightly higher prevalences of newly diagnosed HIV with kiosk versus bedside testing (phase 1, 0%; phase 3, 0.2%; phase 4, 0.5%). Compared to patients tested at the bedside, patients tested via the kiosk were significantly younger, more likely to be female, to be black, and to report high risk behaviours. ED-based HIV screening via a registration-based kiosk was feasible, yielded similar proportions of testing, and increased the proportion of engagement of higher-risk patients in testing.

    Beta-blockers suppress the adverse effects of chronic activation of the sympathetic nervous system-which plays an important role in the progression of cardiovascular disease- and the drugs are also recommended as primary therapy in other diverse medical conditions that present treatment problems. For many patients with atrial fibrillation, a common condition that poses a high risk of stroke, heart rate control with beta-blockers is increasingly seen as a critical therapeutic component. Similarly, perioperative beta-blocker use provides clinical benefits in patients undergoing noncardiac surgery who are at risk of cardiac events. In migraine therapy, beta-blockers are well established as effective agents for prophylaxis, and beta-blockers may reduce levels of C-reactive protein, a sensitive marker of inflammation in cardiovascular disease. Reviewing the role of beta-blockers in several ancillary conditions should help illuminate various aspects of the complex progression of cardiovascular disease and clarify the drugs' various therapeutic benefits.

    A 49-year-old female with a history of several neurosurgical and otolaryngologic procedures for occipital meningioma and cerebrospinal fluid leaks was diagnosed with pneumocephalus after a one hour flight on a domestic jet airliner. Despite multiple operations, the air appeared to enter the cranium through a weak portion of the skull base due to the low atmospheric pressure in the cabin. The intracranial air was absorbed with conservative management. The patient was recommended not to fly before a definite diagnostic work up and a sealing procedure for the cerebrospinal fluid leak site had been performed. Recent advances in aviation technology have enabled many people to travel by air, including individuals with medical conditions. Low cabin pressure is not dangerous to healthy individuals; however, practicing consultant neurosurgeons should understand the cabin environment and prepare high risk patients for safe air travel.

    Liver transplantation offers excellent long-term survival for hepatocellular carcinoma (HCC) patients who fall within established criteria. For those outside such criteria, or with high-risk pathologic features in the explant, HCC recurrence rates are higher. We conducted a multicenter phase I trial of sorafenib in liver transplantation patients with high-risk HCC. Subjects had HCC outside the Milan criteria (pre- or post-transplant), poorly differentiated tumors, or vascular invasion. We used a standard 3+3 phase I design with a planned duration of treatment of 24 weeks. Correlative studies included the number of circulating endothelial cells (CECs), plasma biomarkers, and tumor expression of p-Erk, p-Akt, and c-Met in tissue micro-arrays. We enrolled 14 patients with a median age of 63 years. Of these, 93% were men and 71% had underlying hepatitis C virus (HCV) and 21% had HBV. The maximum tolerated dose of sorafenib was 200 mg BID. Grade 3-4 toxicities seen in >10% of subjects included leukopenia (21%), elevated gamma-glutamyl transferase (21%), hypertension (14%), hand-foot syndrome (14%) and diarrhea (14%). Over a median follow-up of 953 days, one patient died and four recurred. The mean CEC number at baseline was 21 cells/4 ml for those who recurred, and 80 cells/4 ml for those who did not (p=0.10). Mean soluble vascular endothelial growth factor receptor-2 levels decreased after 1 month on sorafenib (p=0.09), but did not correlate with recurrence. There was a trend for tumor c-Met expression to correlate with increased risk of recurrence. Post-transplant sorafenib was found to be feasible and tolerable at 200 mg PO BID. The effect of post-transplant sorafenib on recurrence-free survival is potentially promising but needs further validation in a larger study. PMID:26020033

    Introduction We hypothesized a relationship between severity of thoracic aortic atheroma (AA) and prevalence of high-risk coronary anatomy (HRCA). Material and methods We investigated AA diagnosed by transesophageal echocardiography and HRCA diagnosed by coronary angiography in 187 patients. HRCA was defined as ≥ 50% stenosis of the left main coronary artery or significant 3-vessel coronary artery disease (≥ 70% narrowing). Results HRCA was present in 45 of 187 patients (24%). AA severity was grade I in 55 patients (29%), grade II in 71 patients (38%), grade III in 52 patients (28%), grade IV in 5 patients (3%), and grade V in 4 patients (2%). The area under receiver operating characteristic curve for AA grade predicting HRCA was 0.83 (p = 0.0001). The cut-off points of AA to predict HRCA was > II grade. The sensitivity and specificity of AA > grade II to predict HRCA were 76% and 81%, respectively. After adjustment for 10 variables with significant differences by univariate regression, AA > grade II was related to HRCA by multivariate regression (odds ratio = 7.5, p< 0.0001). During 41-month follow-up, 15 of 61 patients (25%) with AA >grade II and 10 of 126 patients (8%) with AA grade ≤ 2 died (p= 0.004). Survival by Kaplan-Meier plot in patients with AA > grade II was significantly decreased compared to patients with AA ≤ grade II (p= 0.002). Conclusions AA > grade II is associated with a 7.5 times increase in HRCA and with a significant reduction in all-cause mortality. PMID:22291734

    A 72-year-old male patient with gall bladder perforation and small intestinal obstruction from impacted gall stone was posted for emergency laparotomy. He had congestive heart failure, severe hypertension at admission and history of multiple other coexisting diseases. On admission, he developed pulmonary oedema from systolic hypertension which was controlled by ventilatory support, nitroglycerine and furosemide. Preoperative international normalized ratio was 2.34 and left ventricular ejection fraction was only 20%. Because of risk of exaggerated fall in blood pressure during induction of anaesthesia (general or neuraxial), a transversus abdominis plane block via combined Petit triangle and subcostal technique was administered and supplemented with Propofol sedation.

    Skin transplantation is a commonly used surgical technique; however, the complication rate, including postoperative infection and delayed wound healing due to inefficient perfusion, is significantly higher in patients suffering from comorbidities. Hence, a subsequent repeat procedure is often necessary. In this report, two case studies are presented in which an octenidine-based antiseptic is used with a tie-over dressing (TOD) instead of povidone iodine (PVP-iodine), following a split-thickness skin graft. The two patients selected were deemed to be at high risk of impaired wound healing due to comorbidities. The first patient, a confirmed smoker with diabetes, presented with a nodular melanoma that was resected and covered with a split-thickness skin graft. After 5 days of negative pressure wound therapy as a TOD, in combination with PVP-iodine, the graft became necrotic. A second split-thickness skin graft was performed and an antiseptic regimen with octenidine in combination with the same TOD resulted in a completely healed transplant. The second patient, also a confirmed smoker with diabetes and receiving oral corticosteroid treatment, was diagnosed with a skin necrosis on her leg. Following the split-thickness skin graft, octenidine and TOD were applied. The patient's skin graft completely healed without any adverse events. These two case studies indicate that the combination of octenidine and TOD following split-thickness skin transplantation is safe, well-tolerated and appears to have positive benefits in the reconstruction of defects in patients with impaired wound healing.

    Currently, recombinant activated factor VII (rFVIIa) (NovoSeven) is indicated for the treatment of spontaneous and surgical bleeding in congenital haemophilia A and B patients with inhibitors to factors VIII (FVIII) and IX (FIX) >5 Bethesda units (BU) worldwide, and in patients with acquired haemophilia, congenital FVII deficiency and Glanzmann's thrombasthenia in Europe. Until April 2003, almost three-quarters of a milion doses of rFVIIa have been administered proving its efficacy and excellent safety record. According to results from initial clinical trials and a large number of case reports, the rFVIIa may be effective not only in treating haemophilia patients but also in treatment of bleeding in patients on oral anticoagulation or heparin, patients with liver diseases, von Willebrand disease (vWD), thrombocytopenia, various platelet defects, congenital or acquired deficiency of FVII, and in subjects without any pre-existing coagulopathy with diffuse life-threatening bleeding triggered by surgery or trauma. This review will briefly summarize rFVIIa mode of action in haemostasis, the current clinical experience with rFVIIa and focus on the alternative use of rFVIIa in patients at the high risk of bleeding in both spontaneous cases and clinical trials reports.

    Melanomas contain distinct cell subpopulations. Several of these subpopulations, including one expressing CD20, may harbor stem cell-like or tumor-initiating characteristics. We hypothesized that patients at high risk of disease recurrence could benefit from an adjuvant anti-CD20 therapy. Therefore, we initiated a small pilot trial to study the effect of the anti-CD20 antibody rituximab in a group of melanoma patients with stage IV metastatic disease who had been rendered without evident disease by way of surgery, chemotherapy and/or radiation therapy. The major objective was safety, while secondary objectives were description of recurrence-free intervals (RFI) and overall survival (OS). Nine patients received rituximab at 375 mg/m(2) qw for 4 weeks followed by a maintenance therapy every 8 weeks. Treatment was discontinued after 2 years or with disease recurrence. Treatment was well tolerated. After a median observation of 42 months, the median neither of RFI nor of OS has been reached. Despite therapy that ended after 2 years, six out of nine patients are still alive and five of them are recurrence-free. Though the patient number is too small for definitive conclusions, our data may represent a first example of the potential therapeutic value of targeting CD20(+) cell populations-at least for a subset of patients.

    Survivors of high-risk surgical operations were previously observed to have significantly higher mean CI, DO2, and VO2 than nonsurvivors. The hypothesis was proposed that increased CI and DO2 are circulatory compensations for increased postoperative metabolism. We tested this hypothesis in two series. In series 1, prospectively allocated by services, mortality and morbidity of the control group were significantly greater than those of the protocol group. In series 2, patients who fulfilled previously defined high-risk criteria were preoperatively randomized to one of three monitoring/treatment groups: CVP-control group, PA-control group and PA-protocol group. Postoperative mortalities in the CVP-control and PA-control groups were not statistically significantly different, but PA-protocol group mortality was significantly reduced compared with its control group. The PA-protocol group had reduced complications, duration of hospitalization, duration in ICU, and mechanical ventilation, and reduced costs when the PA catheter was placed preoperatively and used to augment circulatory responses.

    Study design: Retrospective cohort study Objective: To describe the outcome and resource use in major spine surgery on high-risk patients, and analyze possible differences between two surgical departments. Methods: Data from the deformity register and medical records of 136 patients, median age 12-years, with neuromuscular and congenital spinal deformities with and without intraspinal pathology, surgically treated by one surgeon from 1997 through 2004 at two departments. H1 with a pediatric multidisciplinary team, and H2 with focus on adult spine. Variables at baseline: age, gender, diagnosis, curve size, and type of surgical procedure. Result variables included clinical and radiographic outcome, surgery time, length of intensive care and hospital stay, relative blood loss, and occurrence of complications during 2 or more years follow-up. Results: There was no perioperative or postoperative mortality, no spinal-cord damage, no neurological or ambulatory function deterioration. The overall complication rate was 36%, and the overall major complication rate was 15.4%. The mean loss of correction was 2° during the follow-up. There were statistically significant differences between the H1 and H2 departments. At H1, deformity correction was better and surgery time shorter. Infections were more frequent at H2 (P = .04; 6/65 at H1; 16/71 at H2), tendency (P = .06) of more department-related complications was higher at H2. Conclusions: Major spine surgery in high-risk patients can be performed safely and with good outcoms. Impact of organization and workplace culture on the outcome might be important and worth further study. PMID:22956923

    Introduction Ultrasound-guided percutaneous placement of a suprapubic cystostomy is a common and generally safe procedure in everyday surgery. In case of adverse patient characteristics such as small bladder capacity or high body mass index, however, the procedure carries an increased risk of severe complications, including bowel perforation. The Suprapur® cystostomy set is supposed to enable a safer procedure. The aim of our work was to evaluate the safety and ease of use of the Suprapur® cystostomy set. Material and methods We prospectively evaluated the Suprapur® set in high-risk patients, having either a small bladder capacity below 250 ml or a BMI above 30 kg/m2. Complications and surgical outcome were monitored. In addition, patients’ contentment and pain during the procedure was assessed with a visual analogue scale (VAS). Possible drawbacks and ease of use were evaluated by customized questionnaires for the operating physician. Results In total, 26 cystostomies were performed by 15 different physicians, 40% (n = 6) of whom were inexperienced first or second year residents. No complications occurred. Mild gross haematuria occurred in 11.5% (n = 4) of cases. Average VAS for pain during and two hours after the procedure was 2.1 (±1.2) and 0.3 (±0.5) respectively. In 91%, (n = 20) of the procedures, the physicians claimed to have felt safe using SUPRAPUR® and more comfortable (82%, n = 18) than with a conventional cystostomy set. Conclusions SUPRAPUR® allows a safe and simple placement of a suprapubic cystostomy even in high-risk patients or in inexperienced hands. It might help to reduce the complications of a common and frequent surgical procedure. PMID:26855806

    All trans retinoic acid (ATRA) has revolutionized the therapy of acute promyelocytic leukemia (APL). Treatment of this leukemia with ATRA in combination with chemotherapy has resulted in complete remission rates >90 % and long-term remission rates above 80 %. Furthermore, the combination of ATRA and arsenic trioxide (ATO) was shown to be safe and effective in frontline treatment and, for patients with low and intermediate risk disease, possibly superior to the standard ATRA and anthracycline-based regimen. However, in spite of this tremendous progress, APL still remains associated with a high incidence of early death due to the frequent occurrence of an abrupt bleeding diathesis. This hemorrhagic syndrome more frequently develops in high-risk APL patients, currently defined as those exhibiting >10 × 10(9)/L WBC at presentation. In addition to high WBC count, other molecular and immunophenotypic features have been associated with high-risk APL. Among them, the expression in APL blasts of the stem/progenitor cell antigen CD34, the neural adhesion molecule (CD56), and the T cell antigen CD2 help to identify a subset of patients at higher risk of relapse and often the expression of these markers is associated with high WBC count. At the molecular level, the short PML/RARA isoform and FLT3-internal tandem duplication (ITD) mutations have been associated with increased relapse risk. These observations indicate that extended immunophenotypic and molecular characterization of APL at diagnosis including evaluation of CD2, CD56, and CD34 antigens and of FLT3 mutations may help to better design risk-adapted treatment in this disease.

    2013-01-01

    Background Invasive pulmonary aspergillosis (IPA) is an infection often occurring in neutropenic patients and has high mortality rates. In recent years, it has been reported that the incidence of IPA has also increased in patients with chronic obstructive pulmonary disease (COPD). The purpose of this study is to investigate the clinical and demographic characteristics and treatment responses of IPA in patients with COPD. Methods Seventy-one patients with a positive culture of Aspergillus from lower respiratory tract samples were examined retrospectively. Eleven (15.4%) of these patients, affected with grade 3 or 4 COPD, had IPA. Results Aspergillus hyphae were detected in lung biopsy in three (27.3%) out of 11 patients and defined as proven IPA; a pathological sample was not taken in the other eight (72.7%) patients, and these were defined as probable IPA. Aspergillus isolates were identified as six cases of Aspergillusfumigatus and three of Aspergillusniger in nine patients, while two isolates were not identified at species level. While five patients required intensive care unit admission, four of them received mechanical ventilation. The most common finding on chest X-ray and computed tomography (CT) (respectively 63.6%, 72.7%) was infiltration. Amphotericin B was the initial drug of choice in all patients and five patients were discharged with oral voriconazole after amphotericin B therapy. Six patients (54.5%) died before treatment was completed. Conclusions IPA should be taken into account in the differential diagnosis particularly in patients with severe and very severe COPD presenting with dyspnea exacerbation, poor clinical status, and a new pulmonary infiltrate under treatment with broad-spectrum antibiotics and steroids.

    Contrast induced nephropathy (CIN) is the third leading cause of hospital acquired renal failure and is associated with significant morbidity and mortality. Chronic kidney disease is the primary predisposing factor for CIN. As estimated glomerular filtration rate<60 ml/1.73 m2 represents significant renal dysfunction and defines patients at high risk. Modifiable risk factors for CIN include hydration status, the type and amount of contrast, use of concomitant nephrotoxic agents and recent contrast administration. The cornerstone of CIN prevention, in both the high and low risk patients, is adequate parenteral volume repletion. In the patient at increased risk for CIN it is often appropriate to withhold potentially nephrotoxic medications, and consider the use of n-acetylcysteine. In patients at increased risk for CIN the use of low or iso-osomolar contrast agents should be utilized and strategies employed to minimize contrast volume. In these patients serum creatinine should be obtained forty-eight hours post procedure and it is often appropriate to continue withholding medications such as metformin or non steroidal anti-inflammatories until renal function returns to normal.

    Purpose. We report a comparison study of vertebral body stapling (VBS) versus a matched bracing cohort for immature patients with moderate (25 to 44°) idiopathic scoliosis (IS). Methods. 42 of 49 consecutive patients (86%) with IS were treated with VBS and followed for a minimum of 2 years. They were compared to 121 braced patients meeting identical inclusion criteria. 52 patients (66 curves) were matched according to age at start of treatment (10.6 years versus 11.1 years, resp. [P = 0.07]) and gender. Results. For thoracic curves 25–34°, VBS had a success rate (defined as curve progression <10°) of 81% versus 61% for bracing (P = 0.16). In thoracic curves 35–44°, VBS and bracing both had a poor success rate. For lumbar curves, success rates were similar in both groups for curves measuring 25–34°. Conclusion. In this comparison of two cohorts of patients with high-risk (Risser 0-1) moderate IS (25–44°), in smaller thoracic curves (25–34°) VBS provided better results as a clinical trend as compared to bracing. VBS was found not to be effective for thoracic curves ≥35°. For lumbar curves measuring 25–34°, results appear to be similar for both VBS and bracing, at 80% success. PMID:26618169

    Contrast medium-induced acute kidney injury (CI-AKI) is associated with morbidity and mortality, but the long-term outcomes of patients who do not develop CI-AKI remain unknown. We assessed clinical end points during long-term follow-up in patients at high risk for nephropathy who did not develop CI-AKI. Patients (n = 135) with impaired renal function (estimated glomerular filtration rate: 30-60 mL/min/1.73 m(2)) were divided into 2 groups according to contrast media (CM) exposure. The primary end point of this study was a composite outcome measure of death or renal failure requiring dialysis. Multivariate analyses identified CM exposure to be independently associated with major adverse long-term outcomes (hazard ratio: 2.3; 95% confidence interval, 1.34-6.52; P = .018). Even when CM exposure does not cause CI-AKI in patients with impaired renal function, in the long term, primary end points occur more frequently in patients exposed to CM than in those with no CM exposure.

    The objective of this study was to characterize organ damage in lupus patients enrolled in the Dallas Regional Autoimmune Disease Registry (DRADR). Retrospective chart review was carried out on 99 patients with 4 or more diagnostic criteria for systemic lupus erythematosus (SLE) and 15 with less than 4 of these criteria, who were designated as having incomplete lupus (ILE). The majority of patients (84%) were African American or Hispanic/Latino; mean disease duration was 9.5 years. The mean damage score was 1.57 (range 0 to 8) and a damage score greater than 0 was present in 64% of the patients. The ILE group had lower mean damage scores (0.67) than the SLE group (1.67; P=0.04), explained in part by the shorter disease duration in the ILE patients (4.33 years vs. 10.24 years; P=0.003). The most prevalent damage category was renal, present in 24% of patients. Malignancies occurred in individuals who were significantly older than those who had renal or peripheral vascular damage (P=0.0007). The findings confirm clinical impressions that the DRADR includes a high-risk lupus population. The ILE patients have less damage but also shorter disease duration, suggesting that this might represent an earlier disease stage. These results are consistent with the hypothesis that ILE patients include a subset that is likely to experience progressive organ damage. Longitudinal study of these patients has significant likelihood of tracking the changes that are correlated with disease progression to SLE. PMID:23715694

    2011-12-01

    The incidence of anal squamous cell carcinoma has increased alarmingly, particularly in high-risk groups such as men who have sex with men and immunosuppressed patients. Infection with an oncogenic strain of the human papillomavirus in the anal canal or perianal skin leads to anal intraepithelial neoplasias (AIN), progressive dysplastic intraepithelial lesions that are the precursors of anal squamous cell carcinoma. AIN can be diagnosed through cytological screening and biopsy guided by high-resolution anoscopy and can be treated using a range of procedures in an effort to prevent progression to invasive anal carcinoma. Given the recent advances in the understanding of this disease, and the increasing calls from experts for the establishment of screening programs to identify AIN, we review current knowledge on the condition, its diagnosis, and treatment from the point of view of dermatology.

    In a large Scottish pedigree, a balanced translocation t (1;11)(q42.1;q14.3) disrupting the DISC1 and DISC2 genes segregates with major mental illness, including schizophrenia and depression. A frame-shift carboxyl-terminal deletion was reported in DISC1 in an American family with schizophrenia, but subsequently found in two controls. Herein, we test one hypothesis utilizing a large scale case-control mutation analysis: uncommon DISC1 variants are associated with high risk for bipolar spectrum disorder. We have analyzed the regions of likely functional significance in the DISC1 gene in 504 patients with bipolar spectrum disorder and 576 ethnically similar controls. Five patients were heterozygous for ultra-rare protein structural variants not found in the 576 controls (p=0.02, one-sided Fisher's exact test) and shown to be ultra-rare by their absence in a pool of 10,000 control alleles. In our sample, ultra-rare (private) protein structural variants in DISC1 are associated with an estimated attributable risk of about 0.5% in bipolar spectrum disorder. These data are consistent with: (i) the high frequency of depression in the large Scottish family with a translocation disrupting DISC1; (ii) linkage disequilibrium analysis demonstrating haplotypes associated with relatively small increases in risk for bipolar disorder (<3-fold odds ratio). The data illustrate how low/moderate risk haplotypes that might be found by the HapMap project can be followed up by resequencing to identify protein structural variants with high risk, low frequency and of potential clinical utility.

    Rates of diabetes and its associated comorbidities have been increasing in the United States, with diabetic foot ulcer treatment representing a large cost to the patient and healthcare system. These ulcers often result in multiple hospital admissions. This study examined readmissions following inpatient care for a diabetic foot ulcer and identified modifiable factors associated with all-cause 30-day readmissions to the inpatient or emergency department (ED) setting. We hypothesized that patients undergoing aggressive treatment would have lower 30-day readmission rates. We identified patient discharge records containing International Classification of Disease ninth revision codes for both diabetes mellitus and distal foot ulcer in the State Inpatient and Emergency Department databases from the Agency for Healthcare Research and Quality, Healthcare Cost and Utilization Project in Florida and New York, 2011-2012. All-cause 30-day return to care visits (ED or inpatient) were analyzed. Patient demographics and treatment characteristics were evaluated using univariate and multivariable regression models. The cohort included 25,911 discharges, having a mean age of 63 and an average of 3.8 comorbidities. The overall rate of return to care was 30%, and 21% of subjects underwent a toe or midfoot amputation during their index stay. The most common diagnosis codes upon readmission were diabetes mellitus (19%) and infection (13%). Patients with a toe or midfoot amputation procedure were less likely to be readmitted within 30 days (odds ratio: 0.78; 95% confidence interval: 0.73, 0.84). Presence of comorbidities, black and Hispanic ethnicities, and Medicare and Medicaid payer status were also associated with higher odds of readmission following initial hospitalization (p < 0.05). The study suggests that there are many factors that affect readmission rates for diabetic foot ulcer patients. Understanding patients at high-risk for readmission can improve counseling and

    Background The purpose of the Finnish Cardiovascular Study (FINCAVAS) is to construct a risk profile – using genetic, haemodynamic and electrocardiographic (ECG) markers – of individuals at high risk of cardiovascular diseases, events and deaths. Methods and design All patients scheduled for an exercise stress test at Tampere University Hospital and willing to participate have been and will be recruited between October 2001 and December 2007. The final number of participants is estimated to reach 5,000. Technically successful data on exercise tests using a bicycle ergometer have been collected of 2,212 patients (1,400 men and 812 women) by the end of 2004. In addition to repeated measurement of heart rate and blood pressure, digital high-resolution ECG at 500 Hz is recorded continuously during the entire exercise test, including the resting and recovery phases. About 20% of the patients are examined with coronary angiography. Genetic variations known or suspected to alter cardiovascular function or pathophysiology are analysed to elucidate the effects and interactions of these candidate genes, exercise and commonly used cardiovascular medications. Discussion FINCAVAS compiles an extensive set of data on patient history, genetic variation, cardiovascular parameters, ECG markers as well as follow-up data on clinical events, hospitalisations and deaths. The data enables the development of new diagnostic and prognostic tools as well as assessments of the importance of existing markers. PMID:16515696

    Background. Consensus guidelines recommend that patients at high risk for choledocholithiasis undergo endoscopic retrograde cholangiopancreatography (ERCP) without additional imaging. This study evaluates factors and outcomes associated with performing magnetic resonance cholangiopancreatography (MRCP) prior to ERCP among patients at high risk for choledocholithiasis. Methods. An institutional administrative database was searched using diagnosis codes for choledocholithiasis, cholangitis, and acute pancreatitis and procedure codes for MRCP and ERCP. Patients categorized as high risk for choledocholithiasis were evaluated. Results. 224 patients classified as high risk, of whom 176 (79%) underwent ERCP only, while 48 (21%) underwent MRCP prior to ERCP. Patients undergoing MRCP experienced longer time to ERCP (72 hours versus 35 hours, p < 0.0001), longer length of stay (8 days versus 6 days, p = 0.02), higher hospital charges ($23,488 versus $19,260, p = 0.08), and higher radiology charges ($3,385 versus $1,711, p < 0.0001). The presence of common bile duct stone(s) on ultrasound was the only independent factor associated with less use of MRCP (OR 0.09, p < 0.0001). Conclusions. MRCP use prior to ERCP in patients at high risk for choledocholithiasis is common and associated with greater length of hospital stay, higher radiology charges, and a trend towards higher hospital charges.

    2016-01-01

    Neuroblastoma (NB) is the most common extra cranial solid tumor of childhood, with 60% of patients presenting with high risk (HR) NB by means of clinical, pathological and biological features. The 5-year survival rate for HR-NB remains below 40%, with the majority of patients suffering relapse from chemorefractory tumor. Immunotherapy is the main strategy against minimal residual disease and clinical experience has mostly focused on monoclonal antibodies (MoAb) against the glycolipid disialoganglioside GD2. Three anti-GD2 antibodies have been tested in the clinic including murine 14G2a, human-mouse chimeric ch14.18 and 3F8. Anti-GD2 MoAb induces cellular cytoxicity against NB and is most effective when effector cells like natural killer cells, granulocytes and macrophages are amplified by cytokines. The combination of cytokines IL-2 and GM-CSF with the anti-GD2 MoAb ch14.18 (Dinutuximab) has shown a significant improvement in outcome for HR-NB. The FDA and EMA approved dinutuximab (Unituxin(R)) in 2015 for the treatment of patients with HR-NB who achieved at least a partial response after multimodality therapy. PMID:26934530

    2015-01-01

    The incidence of infection following implantation of cardiovascular implantable electronic devices (CIEDs) is increasing, as is the number of pulse generator replacements and upgrades. The rate of infections is rising faster than the rate of device implantation, mainly due to the increasing age and number of comorbidities of patients receiving the devices. Patients with a CIED infection usually require hospitalisation, multiple consultations, prolonged intravenous antibiotics and, in the majority of cases, CIED explantation and replacement. A significant proportion die of their infection. CIED infection therefore represents a substantial health and economic burden, and management of infections is critical. Numerous risk factors have been identified including host, procedure and device-related factors. Established strategies for preventing CIED infections include intravenous antibiotics and aseptic techniques. The TYRX™ Absorbable Antibacterial Envelope offers potential as an effective method to reduce CIED infections. Several studies have found a statistically significant association between antibacterial envelope use and reduced incidence of CIED infection in high-risk patients. A prospective, randomised trial to further evaluate this potentially important strategy for CIED infection prophylaxis is underway. PMID:26835101

    BACKGROUND--Identification of patients at risk for progression of coronary stenosis and adverse clinical events while awaiting coronary angioplasty is desirable. OBJECTIVE--To determine the standard clinical or angiographic variables, or both, present at initial angiography associated with the development of adverse coronary events (unstable angina, myocardial infarction, and angiographic total coronary occlusion) in patients awaiting routine percutaneous transluminal coronary angioplasty (PTCA). PATIENTS AND METHODS--Consecutive male patients on a waiting list for routine PTCA. Routine clinical details were obtained at initial angiography. Stenosis severity was measured using computerised angiography. OUTCOME MEASURES--Development of one or more of myocardial infarction, unstable angina, or angiographic total coronary occlusion while awaiting PTCA were recorded as an adverse event. RESULTS--Some 214 of 219 patients underwent a second angiogram. One had a fatal myocardial infarction and four (2%) were lost to follow up. Fifty patients (23%) developed one or more adverse events (myocardial infarction five, unstable angina 35, total coronary occlusion 23) at a median (range) interval of 8 (3-25) months. Twenty (57%) of the 35 patients with unstable angina developed adverse events compared with 30 (17%) of the 180 with stable angina (P = 0.0001). Plasma triglyceride concentration was 2.6 (1.2) mmol/l in patients with adverse coronary events compared with 2.2 (1.1) mmol/l in those without such events (P < 0.05). Patients with adverse events were younger than those without (54 (9) years v 58 (9) years, P < 0.01). The relative risk of an adverse event in patients with unstable angina and increased plasma triglyceride concentrations was 6.9 compared with those presenting with stable angina and a normal triglyceride concentration (P < 0.02). CONCLUSIONS--The study shows that adverse events are not uncommon in patients awaiting PTCA. Patients at high risk for adverse events

    Vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/VC%, PEF, MEF25, MEF50, MEF75, TLC, TGV, pulmonary residual volume (PRV), Raw, Rin, Rcx, DLCO-SB, DLCO-SS/VA, PaO2, and PaCO2 were determined in 40 patients with focal pulmonary tuberculosis. Changes were found in lung volumes and capacities in 75%, impaired bronchial patency and pulmonary gas exchange dysfunction were in 57.5 and 25%, respectively. The lung volume and capacity changes appeared mainly as increased TGV and PRV; impaired bronchial patency presented as decreased MEF50, MEF75, and FEV1/VC%; pulmonary gas exchange dysfunction manifested itself as reduced DLCO-SB, PaO2, and PaCO2. The magnitude of the observed functional changes was generally slight. TGV and PRL increased up to 148-187 and 142-223% of the normal values, respectively; MEF50, MEF75, FEV1/VC%, and DLCO decreased to 59-24, 58-26, 78-57, and 78-67% of the normal values and PaO2 and PaCO2 did to 79-69 and 34-30 cm Hg.

    The frequency of breakthrough invasive fungal diseases (IFDs) during echinocandin therapy is unclear. We retrospectively analyzed 534 hematologic patients treated with echinocandin (caspofungin, N = 55; micafungin, N = 306; anidulafungin, N = 173). Four proven IFDs were found, caused by Candida parapsilosis (N = 2), C. parapsilosis and Candida glabrata (N = 1), and Fusarium species (N = 1). Four cases of possible IFDs were observed, all showing pulmonary infection. One case showed features suggestive of hepatosplenic candidiasis. Six of these eight cases had previously received the purine analog clofarabine. Breakthrough IFD during echinocandin treatment occurred infrequently (1.5 %), caused predominantly by Candida species. Clofarabine usage was an important risk factor. PMID:23949318

    Purpose. To analyze our experience with endovascular stent-grafting of descending aortic aneurysms in high-risk patients. Methods. Nineteen patients underwent endovascular stent-graft repair of descending aortic aneurysms using the Talent Stent Graft System (Medtronic). All patients were considered high-risk for open surgical repair due to their age, requirement for emergency surgery, and comorbidities. Computed tomography and/or MR tomography were performed at 3, 6 and 12 months postoperatively and thereafter every 12 months. Results. Secondary technical success was 100%. Thirty-day mortality was 5%. Incidence of postoperative stroke and paraplegia were 5% each. One patient required a second stent-graft due to a type I endoleak during the same hospital stay (primary technical success 95%). All patients have been followed for a median of 20 months. No migration, wire fractures or endoleak appeared during follow-up. Conclusion. Endovascular stent-grafting had a low 30-day mortality and morbidity in high-risk patients. One patient developed an aortoesophageal fistula 40 days after stent implantation. Stent-graft repair is a valuable supplement to surgical therapy in high-risk patients.

    High-risk prostate cancer represents a pretentious clinical problem since a significant number of its patients will relapse and progress after radical prostatectomy. Neoadjuvant chemotherapy may be valuable since its efficacy in hormone-resistant prostate cancer has been established. In this paper, we report studies of neoadjuvant chemotherapies that have been used in high-risk patients prior to radical prostatectomy. Even though the results regarding the prognostic surrogates are not significant, the effects on clinical and pathological outcomes are promising, while toxicity in most of the studies is in the expected field.

    It is not well established whether the incident outcomes of the clinical high-risk (CHR) syndrome for psychosis are diagnostically specific for psychosis or whether CHR patients also are at elevated risk for a variety of nonpsychotic disorders. We collected 2 samples (NAPLS-1, PREDICT) that contained CHR patients and a control group who responded to CHR recruitment efforts but did not meet CHR criteria on interview (help-seeking comparison patients [HSC]). Incident diagnostic outcomes were defined as the occurrence of a SIPS-defined psychosis or a structured interview diagnosis from 1 of 3 nonpsychotic Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) groups (anxiety, bipolar, or nonbipolar mood disorder), when no diagnosis in that group was present at baseline. Logistic regression revealed that the CHR vs HSC effect did not vary significantly across study for any emergent diagnostic outcome; data from the 2 studies were therefore combined. CHR (n = 271) vs HSC (n = 171) emergent outcomes were: psychosis 19.6% vs 1.8%, bipolar disorders 1.1% vs 1.2%, nonbipolar mood disorders 4.4% vs 5.3%, and anxiety disorders 5.2% vs 5.3%. The main effect of CHR vs HSC was statistically significant (OR = 13.8, 95% CI 4.2–45.0, df = 1, P < .001) for emergent psychosis but not for any emergent nonpsychotic disorder. Sensitivity analyses confirmed these findings. Within the CHR group emergent psychosis was significantly more likely than each nonpsychotic DSM-IV emergent disorder, and within the HSC group emergent psychosis was significantly less likely than most emergent nonpsychotic disorders. The CHR syndrome is specific as a marker for research on predictors and mechanisms of developing psychosis. PMID:26272875

    Objective Drug–drug interaction (DDI) alerting is an important form of clinical decision support, yet physicians often fail to attend to critical DDI warnings due to alert fatigue. We previously described a model for highlighting patients at high risk of a DDI by enhancing alerts with relevant laboratory data. We sought to evaluate the effect of this model on alert adherence in high-risk patients. Methods A 6-month randomized controlled trial involving 1029 outpatient physicians was performed. The target interactions were all DDIs known to cause hyperkalemia. Alerts in the intervention group were enhanced with the patient's most recent potassium and creatinine levels. The control group received unmodified alerts. High -risk patients were those with baseline potassium >5.0 mEq/l and/or creatinine ≥1.5 mg/dl (132 μmol/l). Results We found no significant difference in alert adherence in high-risk patients between the intervention group (15.3%) and the control group (16.8%) (p=0.71). Adherence in normal risk patients was significantly lower in the intervention group (14.6%) than in the control group (18.6%) (p<0.01). In neither group did physicians increase adherence in patients at high risk. Conclusions Physicians adhere poorly to hyperkalemia-associated DDI alerts even in patients with risk factors for a clinically significant interaction, and the display of relevant laboratory data in these alerts did not improve adherence levels in the outpatient setting. Further research is necessary to determine optimal strategies for conveying patient-specific DDI risk. PMID:23161895

    Identifying patients at high risk of carrying pathogenic variants in genes is a crucial part of providing both accurate counseling and evidence-based treatment recommendations. Current risk assessment models have strengths and weaknesses that may limit their applicability to specific clinical circumstances. Clinicians must have knowledge regarding variations in available models, how they should be used, and what data they can expect from specific models. In addition, indications for genetic testing are expanding, and the adoption of next-generation sequencing has allowed the creation of multigene testing panels. Complex consequences of panel testing have included an increase in the incidence of identifying variants of uncertain significance and the identification of pathogenic variants in genes for which treatment guidelines are not available. Women diagnosed with breast cancer who carry pathogenic variants in genes with proven associations with breast cancer (BRCA1/2) or highly likely associations (PTEN, PALB2) require additional risk assessment to facilitate treatment decisions that will limit in-breast tumor recurrence and contralateral breast cancer.

    White light colonoscopy is the current gold standard for early detection and treatment of colorectal cancer, but emerging data suggest that this approach is inherently limited. Even the most experienced colonoscopists, under optimal conditions, miss at least 15-25% of adenomas. There is an unmet clinical need for an adjunctive modality to white light colonoscopy with improved lesion detection and characterization. Optical molecular imaging with exogenously administered organic fluorochromes is a burgeoning imaging modality poised to advance the capabilities of colonoscopy. In this proof-of-principle clinical trial, we investigated the ability of a custom-designed fluorescent colonoscope and indocyanine green, a clinically approved fluorescent blood pool imaging agent, to visualize polyps in high risk patients with polyposis syndromes or known distal colonic masses. We demonstrate (1) the successful performance of real-time, wide-field fluorescence endoscopy using off-the-shelf equipment, (2) the ability of this system to identify polyps as small as 1 mm, and (3) the potential for fluorescence imaging signal intensity to differentiate between neoplastic and benign polyps.

    Hospital-associated venous thromboembolism (VTE) is a leading cause of premature death and disability worldwide. Evidence-based guidelines recommend that anticoagulant thromboprophylaxis be given to hospitalised medical patients at risk of VTE, but suggest against routine use of thromboprophylaxis beyond the hospital stay. The MARINER study is a randomised, double-blind, placebo-controlled trial to evaluate the efficacy and safety of thromboprophylaxis using rivaroxaban, begun at hospital discharge and continued for 45 days, for preventing symptomatic VTE in high-risk medical patients. Eligible patients are identified using the International Medical Prevention Registry on Venous Thromboembolism (IMPROVE VTE) risk score, combined with a laboratory test, D-dimer. The rivaroxaban regimen is 10 mg once daily for patients with CrCl ≥ 50 ml/min, or 7.5 mg once daily for patients with CrCl ≥ 30 ml/min and < 50 ml/min. The primary efficacy outcome is the composite of symptomatic VTE (lower extremity deep-vein thrombosis and non-fatal pulmonary embolism) and VTE-related death. The principal safety outcome is major bleeding. A blinded clinical events committee adjudicates all suspected outcome events. The sample size is event-driven with an estimated total of 8,000 patients to acquire 161 primary outcome events. Study design features that distinguish MARINER from previous and ongoing thromboprophylaxis trials in medically ill patients are: (i) use of a validated risk assessment model (IMPROVE VTE) and D-dimer determination for identifying eligible patients at high risk of VTE, (ii) randomisation at the time of hospital discharge, (iii) a 45-day treatment period and (iv) restriction of the primary efficacy outcome to symptomatic VTE events.

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

    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

    Background Rates of violence in persons identified as high risk by structured risk assessment instruments (SRAIs) are uncertain and frequently unreported by validation studies. Aims To analyse the variation in rates of violence in individuals identified as high risk by SRAIs. Method A systematic search of databases (1995-2011) was conducted for studies on nine widely used assessment tools. Where violence rates in high-risk groups were not published, these were requested from study authors. Rate information was extracted, and binomial logistic regression was used to study heterogeneity. Results Information was collected on 13 045 participants in 57 samples from 47 independent studies. Annualised rates of violence in individuals classified as high risk varied both across and within instruments. Rates were elevated when population rates of violence were higher, when a structured professional judgement instrument was used and when there was a lower proportion of men in a study. Conclusions After controlling for time at risk, the rate of violence in individuals classified as high risk by SRAIs shows substantial variation. In the absence of information on local base rates, assigning predetermined probabilities to future violence risk on the basis of a structured risk assessment is not supported by the current evidence base. This underscores the need for caution when such risk estimates are used to influence decisions related to individual liberty and public safety. PMID:24590974

    Despite state of the art local therapy a significant portion of men with high-risk prostate cancer develop progressive disease. Neoadjuvant systemic therapy prior to radical prostatectomy (RP) is an approach which can potentially maximize survival outcomes in patients with localized disease. This approach is under investigation with a wide array of agents and provides an opportunity to assess pathologic and biologic activity of novel treatments. The aim of this review is to explore the past and present role of neoadjuvant therapy prior to definitive therapy with RP in patients with high-risk localized or locally advanced disease. The results of neoadjuvant ADT, including use of newer agents such as abiraterone and enzalutamide, are promising. Neoadjuvant chemotherapy, primarily with docetaxel, with or without ADT has also demonstrated efficacy in men with high-risk disease. Other novel agents targeting the vascular endothelial growth factor receptor (VEGFR), epidermal growth factor receptor (EGFR), platelet derived growth factor receptor (PDGFR), clusterin, and the immune system are currently under investigation and have led to variable results in early clinical trials. Despite optimistic data, approval of neoadjuvant therapy prior to RP in patients with high-risk prostate cancer will depend on positive results from well designed phase III trials. PMID:23943203

    Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL) is usually an incidental diagnosis in patients with early–intermediate stage disease. However, most patients with a diagnosis of CLL will subsequently have significant morbidity and die from their disease and its complications. For these patients, CLL is not the ‘good leukemia’ with a predictably ‘benign’ outcome. Indeed, we can now identify a cohort of patients with high-risk CLL at diagnosis who will have rapid disease progression, poor response to treatment, and poor survival based on prognostic methods developed from an improved understanding of the biology of CLL. The concomitant development of improved treatments has led to risk-adjusted management approaches that could improve outcomes. We discuss the clinical and laboratory components of comprehensive risk evaluation of patients with CLL and our approach to the management of patients with a high to very high risk of disease progression and poor outcome. In addition, we review the challenges and prospects for improving prognostic precision and the development of new drugs to improve the treatment of patients with CLL with a high risk of adverse outcome.

    Purpose: To evaluate the efficacy and safety profile of vinorelbine and estramustine in combination with three-dimensional conformational radiotherapy (3D-CRT) in patients with localized high-risk prostate cancer. Methods and Materials: Fifty patients received estramustine, 600 mg/m{sup 2} daily, and vinorelbine, 25 mg/m{sup 2}, on days 1 and 8 of a 21-day cycle for three cycles in combination with 8 weeks of 3D-CRT (total dose of 70.2 gray [Gy] at 1.8-Gy fractions or 70 Gy at 2.0-Gy fractions). Additionally, patients received luteinizing hormone-releasing hormone analogs for 3 years. Results: All patients were evaluated for response and toxicity. Progression-free survival at 5 years was 72% (95% confidence interval [CI]: 52-86). All patients who relapsed had only biochemical relapse. The most frequent severe toxicities were cystitis (16% of patients), leucopenia (10% of patients), diarrhea (10% of patients), neutropenia (8% of patients), and proctitis (8% of patients). Six patients (12%) did not complete study treatment due to the patient's decision (n = 1) and to adverse events such as hepatotoxicity, proctitis, paralytic ileus, and acute myocardial infarction. Conclusions: Vinorelbine and estramustine in combination with 3D-CRT is a safe and effective regimen for patients with localized high-risk prostate cancer. A randomized trial is needed to determine whether the results of this regimen are an improvement over the results obtained with radiotherapy and androgen ablation.

    Neuroblastoma is an aggressive pediatric tumor accounting for ~15% of cancer-associated mortalities in children. Despite the current intensive therapy, >50% of high-risk patients experience tumor relapse or regrowth caused by the activation of minimal residual disease (MRD). Although several MRD detection protocols using various reverse transcription-quantitative polymerase chain reaction (RT-qPCR) markers have been reported to evaluate the therapeutic response and disease status of neuroblastoma patients, their clinical significance remains elusive. The present study reports two high-risk neuroblastoma patients, whose MRD was consecutively monitored using 11 RT-qPCR markers (CHRNA3, CRMP1, DBH, DCX, DDC, GABRB3, GAP43, ISL1, KIF1A, PHOX2B and TH) during their course of treatment. The two patients initially responded to the induction therapy and reached MRD-negative status. The patients' MRD subsequently became positive with no elevation of their urinary homovanillic acid, urinary vanillylmandelic acid and serum neuron-specific enolase levels at 13 or 19 weeks prior to the clinical diagnosis of tumor relapse or regrowth. The present cases highlight the possibility of consecutive MRD monitoring using 11 markers to enable an early detection of tumor relapse or regrowth in high-risk neuroblastoma patients.

We analyzed whether the HAS-BLED score accurately identifies patients at high risk of major bleeds during VKA treatment for acute VTE. Methods Medical records of 537 patients with acute VTE (primary diagnosis pulmonary embolism in 223, deep vein thrombosis in 314) starting VKA treatment between 2006-2007 were searched for items on the HAS-BLED score and the occurrence of major bleeds during the first 180 days of follow-up. The hazard ratio (HR) for the occurrence of major bleeds comparing non-high with high-risk patients as defined by a HAS-BLED score ≥ 3 points was calculated using Cox-regression analysis. Results Major bleeds occurred in 11/537 patients (2.0%, 5.2/100 person years, 95% CI 2.8-9.2). Cumulative incidences of major bleeds were 1.3% (95% CI 0.1-2.5) in the non-high (HAS-BLED < 3) and 9.6% (95%CI 2.2-17.0) in the high-risk group (HAS-BLED ≥ 3), (p <0.0001 by Log-Rank test), with a HR of 8.7 (95% CI 2.7-28.4). Of the items in the HAS-BLED score, abnormal renal function (HR 10.8, 95% CI 1.9-61.7) and a history of bleeding events (HR 10.4, 95% CI 2.5-42.5) were independent predictors of major bleeds during follow-up. Conclusion Acute VTE patients with a HAS-BLED score ≥ 3 points are at increased risk of major bleeding. These results warrant for correction of the potentially reversible risk factors for major bleeding and careful International Normalized Ratio monitoring in acute VTE patients with a high HAS-BLED score.

    Objective The purpose of this study was to evaluate the prognosis according to the number of high risk factors in patients with high risk factors after radical hysterectomy and adjuvant chemoradiation therapy for early stage cervical cancer. Methods Clinicopathological variables and clinical outcomes of patients with FIGO (International Federation of Gynecology and Obstetrics) stage IB1 to IIA cervical cancer who had one or more high risk factors after radical hysterectomy and adjuvant chemoradiation therapy were retrospectively analyzed. Patients were divided into two groups according to the number of high risk factors (group 1, single high risk factor; group 2, two or more high risk factors). Results A total of 93 patients were enrolled in the present study. Forty nine out of 93 (52.7%) patients had a single high risk factor, and 44 (47.3%) had two or more high risk factors. Statistically significant differences in stage and stromal invasion were observed between group 1 and group 2. However, age, histology, tumor size, and lymphovascular space invasion did not differ significantly between the groups. Distant recurrence occurred more frequently in group 2, and the probability of recurrence and death was higher in group 2. Conclusion Patients with two or more high risk factors had worse prognosis in early stage cervical cancer. For these patients, consideration of new strategies to improve survival may be worthwhile. Conduct of further clinical trials is warranted for development of adjuvant treatment strategies individualized to each risk group. PMID:27200308

    Integrating current evidence with fundamental concepts from decision analysis suggests that management of patients with pulmonary nodules should begin with estimating the pretest probability of cancer from the patient's clinical risk factors and computed tomography characteristics. Then, the consequences of treatment should be considered, by comparing the benefits of surgery if the patient has lung cancer with the potential harm if the patient does not have cancer. This analysis determines the "treatment threshold," which is the point around which the decision centers. This varies widely among patients depending on their cardiopulmonary reserve, comorbidities, and individual preferences. For patients with a very low probability of cancer, careful observation with serial computed tomography is warranted. For those with a high probability of cancer, surgical diagnosis is warranted. For patients in the intermediate range of probabilities, either computed tomography-guided fine-needle aspiration biopsy or positron emission tomography, possibly followed by computed tomography-guided fine-needle aspiration biopsy, is best. Patient preferences should be considered because the absolute difference in outcome between strategies may be small. The optimal approach to the management of patients with pulmonary nodules is evolving as technologies develop. Areas of uncertainty include quantifying the hazard of delayed diagnosis; determining the optimal duration of follow-up for ground-glass and semisolid opacities; establishing the roles of volumetric imaging, advanced bronchoscopic technologies, and limited surgical resections; and calculating the cost-effectiveness of different strategies.

    Objective To evaluate the technical feasibility and clinical efficacy of percutaneous transhepatic cholecystolithotomy under fluoroscopic guidance in high-risk surgical patients with acute cholecystitis. Materials and Methods Sixty-three consecutive patients of high surgical risk with acute calculous cholecystitis underwent percutaneous transhepatic gallstone removal under conscious sedation. The stones were extracted through the 12-Fr sheath using a Wittich nitinol stone basket under fluoroscopic guidance on three days after performing a percutaneous cholecystostomy. Large or hard stones were fragmented using either the snare guide wire technique or the metallic cannula technique. Results Gallstones were successfully removed from 59 of the 63 patients (94%). Reasons for stone removal failure included the inability to grasp a large stone in two patients, and the loss of tract during the procedure in two patients with a contracted gallbladder. The mean hospitalization duration was 7.3 days for acute cholecystitis patients and 9.4 days for gallbladder empyema patients. Bile peritonitis requiring percutaneous drainage developed in two patients. No symptomatic recurrence occurred during follow-up (mean, 608.3 days). Conclusion Fluoroscopy-guided percutaneous gallstone removal using a 12-Fr sheath is technically feasible and clinically effective in high-risk surgical patients with acute cholecystitis.

    We evaluated 193 consecutive unstable angina patients by clinical features, hospital course and electrocardiography. All patients were managed medically. Of the 193 patients, 150 (78%) had a technetium-99m pyrophosphate (Tc-PYP) myocardial scintigram after hospitalization. Of these, 49 (33%) had positive scintigrams. At a follow-up of 24.9 +/- 10.8 months after hospitalization, 16 of 49 patients (33%) with positive scintigrams died from cardiac causes, compared with six of 101 patients (6%) with negative scintigrams (p less than 0.001). Of 49 patients with positive scintigrams, 11 (22%) had had nonfatal myocardial infarction at follow-up, compared with seven of 101 patients (7%) with negative scintigrams (p less than 0.01). Age, duration of clinical coronary artery disease, continuing angina during hospitalization, ischemic ECG, cardiomegaly and a history of heart failure also correlated with cardiac death at follow-up. Ischemic ECG and a history of angina with a crescendo pattern also correlated with nonfatal infarction at follow-up. Patients with continuing angina, an ischemic ECG and a positive scintigram constituted a high-risk unstable angina subgroup with a survival rate of 58% at 6 months, 47% at 12 months and 42% at 24 and 36 months. We conclude that the assessment of clinical features, hospital course, ECG and Tc-PYP scintigraphy may be useful in identifying high-risk unstable angina patients.

    The aim of the present article was to present an alternative endovascular treatment for type II thoracoabdominal aortic aneurysm that would have the advantage of limiting the duration of the procedure and the use of contrast. A high-risk patient was admitted to our Vascular Unit for type II thoracoabdominal aneurysm according to Crawford's classification. Two thoracic stent-grafts (Valiant Captivia, Medtronic, Pewaukee, WI, USA), a bifurcated stent-graft (Endurant Medtronic) and two multilayer stents (Cardiatis SA, Isnes, Belgium) were deployed. No postoperative major complications were observed. Operative time and use of contrast material were 45 min and 80 mL, respectively. Computed angiography tomography at 1 and 6 months showed patency of visceral and renal arteries and progressive thrombosis of the aneurysmal sac. This stent-graft treatment in combination with multilayer stent could be an alternative treatment for thoracoabdominal aneurysm in high-risk patients. PMID:24013540

    Pulmonary Hypertension is a serious complication of sickle cell disease (SCD), with high morbidity and mortality. Endothelin (ET)-1, a potent vasoconstrictor elevated in SCD, acts through the ET receptors (ETR), ETR-A and ETR-B. Bosentan and ambrisentan are ETR blockers used in primary pulmonary hypertension. We report on the use of ETR blocking agents in a cohort of 14 high-risk SCD adult patients with pulmonary hypertension. Patients underwent right heart catheterization, 6-min walk test, echocardiogram, physical examination and blood work-up before starting ETR blockers. Eight patients received ETR blockers as initial therapy; six patients were already taking sildenafil. Over more than 6 months of therapy, sequential measurements of 6-min walk distance increased significantly (baseline 357 +/- 22 to 398 +/- 18 m at 5-6 months, P < 0.05). Downward trends were observed for amino-terminal brain natriuretic peptide and tricuspid regurgitant velocity. Pulmonary artery mean pressures decreased in three patients that had repeat right heart catheterization (44-38 mmHg). Adverse events were: increased serum alanine aminotransferase (2), peripheral oedema (4), rash (1), headache (3), decreased haemoglobin (2). Therapy was stopped in two patients who were switched then to the other ETR blocker agent. These data suggest preliminary evidence for the benefit of bosentan and ambrisentan in pulmonary hypertension in SCD. PMID:19775299

    Stratifying risk of patients with acute coronary syndrome (ACS) in the emergency department (ED) remains a frequent challenge. When ST-elevation criteria are absent, current recommendations rely upon insensitive and time-intensive methods such as the electrocardiogram and cardiac enzyme testing. Here, we report on a series of cases, where emergency physicians used a simplified model for identifying regional wall motion abnormalities by point-of-care echocardiography in patients presenting with chest pain to the ED. With the use of a simplified model described herein, high-risk patients with ACS were identified rapidly in a cohort usually difficult to risk stratify. PMID:24745875

    Deep venous thrombosis is a serious consequence of major orthopaedic surgery and non invasive screening with either venous ultrasound or impedance plethysmography is unreliable for detecting or excluding DVT in this group. A new method of thrombus detection has been devised using Tc-99m labelled inhibited recombinant tissue plasminogen activator. The accuracy of scanning with this new radiopharmaceutical in asymptomatic high risk patients was evaluated using venography as the gold standard. 36 consecutive asymptomatic high risk patients (17 total hip, 19 total knee replacements) underwent both a contrast venogram on the operated leg and scintigraphic scan 7 days following operation. Scintigraphic imaging was performed at 4 hours post injection. For the purpose of this analysis, each venogram was divided into a proximal and a distal segment. Venograms were interpreted as being positive, negative or uninterpretable in each segment. Similar analysis of the scintigraphic scans was performed except that all segments were considered to be of diagnostic quality. 57 segments were able to be analysed. Of the 13 thrombosed segments (1 proximal, 12 calf), 12 had positive scans; in the 44 non thrombosed segments, 40 had negative scans. Thus in detecting lower limb thrombosis, scanning had a sensitivity of 92% and a specificity of 91%. Scintigraphic scanning with this new radiopharmaceutical permits accurate detection of thrombus in high risk patients.

    Neuroblastoma is an aggressive solid tumor that leads to tumor relapse in more than half of high-risk patients. Minimal residual disease (MRD) is primarily responsible for tumor relapses and may be detected in peripheral blood (PB) and bone marrow (BM) samples. To evaluate the disease status and treatment response, a number of MRD detection protocols based on either common or distinct markers for PB and BM samples have been reported. However, the correlation between the expression of MRD markers in PB and BM samples remains elusive in the clinical samples. In the present study, the expression of 11 previously validated MRD markers (CHRNA3, CRMP1, DBH, DCX, DDC, GABRB3, GAP43, ISL1, KIF1A, PHOX2B and TH) was determined in 23 pairs of PB and BM samples collected from seven high-risk neuroblastoma patients at the same time point, and the sample was scored as MRD-positive if one of the MRD markers exceeded the normal range. Although the number of MRD-positive samples was not significantly different between PB and BM samples, the two most sensitive markers for PB samples (CRMP1 and KIF1A) were different from those for BM samples (PHOX2B and DBH). There was no statistically significant correlation between the expression of MRD markers in the PB and BM samples. These results suggest that MRD markers were differentially expressed in PB and BM samples from high-risk neuroblastoma patients. PMID:26722317

    Soft tissue defects in patients with chronic comorbidities place these patients at high risk for amputation, even when their underlying problems are controlled. The reverse sural artery flap is an effective technique for closing these defects and saving the limb. We retrospectively reviewed 15 consecutive high-risk patients who underwent a sural artery flap procedure between 2003 and 2005 as a final attempt to prevent having a below-the-knee amputation. All of our patients presented with at least 1 comorbidity, with a majority having multiple. Comorbidities in our patient population consisted primarily of diabetes mellitus with neuropathy, critical limb ischemia, end-stage renal disease, and various cardiomyopathies. All patients presented before surgical intervention with a longstanding history of chronic ulcerations that had failed multiple healing strategies. Ulcerations were located at various regions of the foot and ankle such as the heel, lateral malleolus, medial malleolus, and the lateral midfoot. Of those 15 procedures, three failed completely and two had complete dermal necrosis with viable adipose tissue that healed secondarily. The remaining ten flaps healed primarily. We used negative pressure therapy preoperatively in seven patients and postoperatively in five patients. We obtained a success rate of 80%. The reverse sural artery flap has many advantages over free flaps, which has made it a viable treatment option in chronic ulcerations that have failed conservative attempts. PMID:17145467

    The occurrence of postoperative pulmonary complications is strongly associated with increased hospital mortality and prolonged postoperative hospital stays. Although protective lung ventilation is commonly used in the intensive care unit, low tidal volume ventilation in the operating room is not a routine strategy. Low tidal volume ventilation, moderate positive end-expiratory pressure, and repeated recruitment maneuvers, particularly for high-risk patients undergoing major abdominal surgery, can reduce postoperative pulmonary complications. Facilitating perioperative bundle care by combining prophylactic and postoperative positive-pressure ventilation with intraoperative lung-protective ventilation may be helpful to reduce postoperative pulmonary complications.

    The paper examines the effects of anaesthesia on circulatory physiology and their implications regarding improvement in perioperative anaesthetic management. Changes to current anaesthetic practice, recommended recently, such as the use of flow monitoring in high risk patients, are already beginning to have an impact in reducing complications but not mortality [1]. Better understanding of the patho-physiology should help improve management even further. Analysis of selected individual clinical trials has been used to illustrate particular areas of patho-physiology and how changes in practice have improved outcome. There is physiological support for the importance of achieving an appropriate rate of oxygen delivery (DO2), particularly following induction of anaesthesia. It is suggested that ensuring adequate DO2 during anaesthesia will avoid development of oxygen debt and hence obviate the need to induce a high, compensatory, DO2 in the post-operative period. In contrast to the usual assumptions underlying strategies requiring a global increase in blood flow [1] by a stroke volume near maximization strategy, blood flow control actually resides entirely at the tissues not at the heart. This is important as the starting point for understanding failed circulatory control as indicated by 'volume dependency'. Local adjustments in blood flow at each individual organ - auto-regulation - normally ensure the appropriate local rate of oxygen supply, i.e. local DO2. Inadequate blood volume leads to impairment of the regulation of blood flow, particularly in the individual tissues with least capable auto-regulatory capability. As demonstrated by many studies, inadequate blood flow first occurs in the gut, brain and kidney. The inadequate blood volume which occurs with induction of anaesthesia is not due to blood volume loss, but probably results from redistribution due to veno-dilation. The increase in venous capacity renders the existing blood volume inadequate to maintain

    The first case of pulmonary talcosis or talc pneumoconiosis related to inhalation of talc during its extraction and processing in mines was described by Thorel in 1896. Pulmonary talcosis is most commonly seen secondary to occupational exposure or intravenous (IV) drug abuse and, occasionally, in excessive use of cosmetic talc. Based on literature review, there has been an increase in reported incidents of pulmonary talcosis due to various forms of exposure to the mineral. We report an 82-year-old man who is diagnosed with Philadelphia chromosome positive pre-B cell acute lymphoblastic leukemia (ALL) treated with palliative imatinib who presented with chronic hemoptysis and dyspnea shortly after his diagnosis. His symptoms were initially thought to be due to an infectious etiology due to his malignancy, immunocompromised state, and radiographic findings until high-resolution computerized tomographic (HRCT) findings showed a diffuse pulmonary fibrosis picture that prompted further questioning and a more thorough history inquiry on his exposure to causative agents of interstitial lung disease. Very often, patients do not recognize their exposure, especially in those whose exposure is unrelated to their occupation. Our case emphasizes the need for thorough and careful history taking of occupational and nonoccupational exposure to known causative agents of interstitial lung disease. PMID:27446215

    Heterotopic ossification is a complication of total hip arthroplasty in 14 to 30% of patients. Significant functional impairment will occur in up to 28% of patients with ectopic bone. The high risk group includes those with preexisting heterotopic bone in either hip, those suffering from hypertrophic osteoarthritis or ankylosing spondylitis and patients who have had multiple procedures on the hip. Fifty-eight patients (67 hips) were irradiated after surgical removal of ectopic bone (53 hips) or received radiation prophylaxis of heterotopic ossification (14 hips). Ninety-five percent of patients had either no bone visible or insignificant amounts of ectopic bone visible on postoperative hip X-rays. Only 5% of patients showed significant persistence of ectopic bone. Postoperative hip function was dramatically improved compared to preoperative function in all patients treated. The importance of early commencement of irradiation is emphasized.

    Patients with hematologic neoplasms frequently experience pulmonary disease. The possibility of a malignant involvement of the lung parenchyma is a well recognized and not unusual event, secondary spread due to lymphoproliferative disorders being the most common situation. Furthermore, the development and the advances in treatment options such as hematopoietic stem cell transplantation, radiation therapy and/or combined drug regimen use have significantly widened the spectrum of non-neoplastic pulmonary complications that can crop up in these patients. Infections, drug/radiation-induced toxicity, and graft-versus-host disease (GVHD)-related complications account by now for most pulmonary problems in hematologic patients and represent a difficult challenge both in diagnostic and in therapeutic terms for the clinician. The aim of this review is to highlight the clinicopathologic spectrum of lung diseases which can occur in the setting of hematologic malignancies. A particular emphasis is devoted to the diagnostic approach, high-resolution computed tomography (HRCT) assuming a key role since different patterns of CT abnormalities are associated with a different yield of the available diagnostic tools and may help in narrowing the differential diagnosis.

    Background: The prediction of coronary artery disease (CAD) by conventional echocardiographic measurements is principally based on the estimation of ejection fraction and regional wall motion abnormality (RWMA). This study aimed to determine whether strain echocardiography of left ventricle measured by velocity vector imaging (VVI) method could detect patients with a high-risk CAD. Methods: In a prospective study, a total of 119 consecutive patients who were assessed for eligibility were categorized into three groups: (1) without CAD as normal (n=59), (2) 1- or 2-vessel disease as low-risk (n=29), and (3) left main and/or 3-vessel disease as high-risk (n=31). The peaks of systolic strain and strain rate from 18 curves of apical views were averaged as global longitudinal strain and strain rate (GLS and GLSR), respectively; the 6 systolic peaks of strain and strain rate at base- and mid-ventricular of short axis views were averaged as mean radial strain rate (MRSR). Results: GLS, GLSR, and basal MRSR of left ventricle were significantly lower in the high-risk group (P=0.047, P=0.004 and P=0.030, respectively). Receiver operating characteristics curve showed that the optimal values of GLS, GLSR, and basal MRSR for detecting the severe CAD were -17%, -1 s-1, and 1.45 s-1 with the sensitivities of 77%, 71%, and 71% and the specificities of 63%, 67%, and 62%, respectively. Conclusion: Decrements in the GLS, GLSR, and basal MRSR of the left ventricle can detect the high-risk CAD cases among patients without RWMA at rest. PMID:26309603

    Background Atrial fibrillation (AF) is associated with an increased risk of stroke. Anticoagulant (AC) therapies are effective at treating AF, but carry with them an increased risk of bleed. Research suggests that a large proportion of AF patients who have high risk of stroke and low risk of bleeding are not currently receiving AC treatment. The goal of this study was to understand the reasons why these patients do not engage in this potentially life-saving treatment. Method Through a self-report online survey, using validated instruments, 1,184 US adults who self-reported a diagnosis of AF were screened for the risk of stroke and bleed. Of these patients, 230 (19.4%) were at high risk of stroke, low risk of bleed, and not currently using an AC treatment, and were asked follow-up questions to assess their reasons for nontreatment, attitudes toward treatment, and attitudes toward dosing regimens. Results The most common reasons patients stopped AC treatment were concerns regarding bleeding (27.8%) and other medical concerns (26.6%), whereas the most common reason cited for not being prescribed an AC in the first place was the use of antiplatelet therapy as an alternative (57.1%). In both cases, potentially erroneous decisions regarding perceived stoke and/or bleeding risk were also a factor. Finally, the largest factors regarding attitudes toward treatment and dosing regimen were instructions from an authority figure (eg, physician, pharmacist) and ease of use, respectively. Conclusion Results suggest that many AF patients who are at high risk of stroke but at low risk of bleed may not be receiving AC due to potentially inaccurate beliefs about risk. This study also found that AF patients place trust in physicians above other factors such as cost when making treatment decisions. Increased education of patients by physicians on the risks and benefits may be a simple strategy to improve outcomes. PMID:27274206

    Despite the good quality of treatment expected with optimized transurethral resection (TUR) and adjuvant Bacillus Calmette-Guérin (BCG) regimen, many high-risk non-muscle invasive bladder cancer (NMIBC) patients recur and progress. According to the EORTC Tables of risk, cases with a score of 10-17 and those with a score of 7-23 should be considered as being at high risk of recurrence and progression, respectively. AUA and NCCN consider all T1 stage tumors, high grade Ta and CIS at high risk of recurrence and progression. Long-term follow-up shows that T1,G3 patients treated with BCG will suffer from up to 45% and 17% rate of recurrence and progression, respectively. Consequently, EAU, AUA and NCCN Guidelines for bladder cancer recommend radical cystectomy as a first treatment option for those patients who failed after two cycles of adjuvant BCG. However, to date, there is no definitive evidence that in this special subgroup of patients an early radical cystectomy is better than any additional salvage strategy, in terms of oncologic outcome. On the other hand, it is well accepted that radical cystectomy is burdened with consistent reduction of overall post-operative quality of life. The reluctance of patient to accept (and of surgeon to recommend) this major extirpative surgery may explain the reduced disease-free survival rate, well documented when radical cystectomy has been extremely delayed. Defining the criteria for the selection of BCG-failure patients for whom any conservative procedure should be definitively abandoned in favor of a timely radical cystectomy has become of critical importance. Recently, clinical, laboratory and pathologic acquisitions allowed the development of more accurate predictive factors for tumor progression in NMIBC. Among these factors, clinical type of BCG-failure, morphology and tumor growth patterns, pathologic sub-staging and immunohistochemistry will play a paramount role in decision-making with these patients in routine

    OBJECTIVE: To describe the prevalence of anemia and of its types in hospitalized patients with pulmonary tuberculosis. METHODS: This was a descriptive, longitudinal study involving pulmonary tuberculosis inpatients at one of two tuberculosis referral hospitals in the city of Rio de Janeiro, Brazil. We evaluated body mass index (BMI), triceps skinfold thickness (TST), arm muscle area (AMA), ESR, mean corpuscular volume, and red blood cell distribution width (RDW), as well as the levels of C-reactive protein, hemoglobin, transferrin, and ferritin. RESULTS: We included 166 patients, 126 (75.9%) of whom were male. The mean age was 39.0 ± 10.7 years. Not all data were available for all patients: 18.7% were HIV positive; 64.7% were alcoholic; the prevalences of anemia of chronic disease and iron deficiency anemia were, respectively, 75.9% and 2.4%; and 68.7% had low body weight (mean BMI = 18.21 kg/m2). On the basis of TST and AMA, 126 (78.7%) of 160 patients and 138 (87.9%) of 157 patients, respectively, were considered malnourished. Anemia was found to be associated with the following: male gender (p = 0.03); low weight (p = 0.0004); low mean corpuscular volume (p = 0.03);high RDW (p = 0; 0003); high ferritin (p = 0.0005); and high ESR (p = 0.004). We also found significant differences between anemic and non-anemic patients in terms of BMI (p = 0.04), DCT (p = 0.003), and ESR (p < 0.001). CONCLUSIONS: In this sample, high proportions of pulmonary tuberculosis patients were classified as underweight and malnourished, and there was a high prevalence of anemia of chronic disease. In addition, anemia was associated with high ESR and malnutrition. PMID:25210963

  10. Long-term outcomes in high-risk patients with non-ST-segment elevation myocardial infarction.

    Greater use of evidence-based therapies has improved outcomes for patients with acute coronary syndromes (ACS) in recent decades. Consequently, more ACS patients are surviving beyond 12 months; however, limited data exist to guide treatment in these patients. Long-term outcomes have not improved in non-ST-segment elevation myocardial infarction (NSTEMI) patients at the same rate seen in ST-segment elevation myocardial infarction patients, possibly reflecting NSTEMI patients' more complex clinical phenotype, including older age, greater burden of comorbidities and higher likelihood of a previous myocardial infarction (MI). This complexity impacts clinical decision-making, particularly in high-risk NSTEMI patients, in whom risk-benefit assessments are problematical. This review examines the need for more effective long-term management of NSTEMI patients who survive ≥12 months after MI. Ongoing risk assessment using objective measures of risk (for bleeding and ischemia) should be used in all post-MI patients. While 12 months appears to be the optimal duration of dual antiplatelet therapy for most patients, this may not be the case for high-risk patients, and more research is urgently needed in this population. A recent subgroup analysis from the DAPT study in patients with or without MI who had undergone coronary stenting (31 % presented with MI; 53 % had NSTEMI) and the prospective PEGASUS-TIMI 54 trial in patients with a prior MI and at least one other risk factor (40 % had NSTEMI) demonstrated that long-term dual antiplatelet therapy improved cardiovascular outcomes but increased bleeding. Further studies will help clarify the role of dual antiplatelet therapy in stable post-NSTEMI patients. PMID:26001907

    The objective of this study was to determine the safety of prophylactic subclavian artery intraaortic balloon pumps (SCA-IABP) in high-risk cardiac surgery patients as a bridge to recovery (BTR). From November 2011 to January 2013, 11 consecutive patients at three institutions underwent prophylactic insertion of a SCA-IABP as a BTR. All patients (n = 11) had preoperative ejection fractions of 30% or less. Patients concurrently underwent one or a combination of the following procedures: coronary artery bypass grafting, mitral valve surgery, aortic valve replacement, left ventricular aneurysm resection, and ventricular/atrial septal defect closure. The primary outcome measure was a composite endpoint of device-related complications (including limb ischemia, stroke, device failure, bleeding requiring reoperation, brachial plexus injury, device-related infection, and vascular complications) and in-hospital mortality. Secondary outcome measures included interval to patient ambulation and postoperative length of stay. There were no device-related complications or in-hospital mortalities in this cohort of 11 consecutive patients. Mean time to ambulation, balloon pump support, and postoperative length of stay were 3.70 ± 2.50 days, 8.50 ± 7.00 days, and 15.9 ± 8.25 days, respectively. Prophylactic SCA-IABPs appear to be safe in high-risk cardiac surgery patients as a BTR. PMID:26313557

    Purpose. The efficacy of chemoembolization of primary and metastatic gestational trophoblastic neoplasms was studied. Methods. Six female patients, 19-33 years old, with high-risk trophoblastic disease were subjected to one to five chemoembolizations in 3-week intervals. Three of the patients had metastases to the liver, 2 had local tumor extension to the pelvic wall, and all 5 had failed initial systemic chemotherapy. The sixth patient was treated for a trophoblastic remnant following surgical expression of a tubal pregnancy. For follow-up, beta hCG levels in urine and serum and dynamic or angiocomputed tomograms were obtained in biweekly to 6-month intervals. Results. Two of 3 patients with liver metastases are alive and free of disease 6 and 7 years after initial chemoembolization. The third is alive at 3 years but with evidence of recurrent disease. Two patients treated for locally invasive trophoblastic disease died 3 months and 4 years, respectively, after initial chemoembolization. One had a 21/2-year remission. The patient treated for a trophoblastic remnant in the tube is alive and free of disease at 6-year follow-up. Hematologic toxicity occurred in only one. Conclusion. Selective chemoembolization in our small series of patients with high-risk trophoblastic disease was equally effective as results reported for multi-drug systemic chemotherapy but had markedly lower renal, liver, and hematologic toxicity.

    This study sought to determine the prevalence of coronary artery-pulmonary artery collaterals in patients with chronic thromboembolic pulmonary hypertension (CTEPH) and to correlate their presence with the degree of clot burden. CTEPH is a treatable cause of severe pulmonary hypertension and right heart failure. Bronchopulmonary collateral vessels have been used as a supplementary diagnostic and prognostic tool for this disease. Coronary artery-pulmonary artery collaterals in this population have not been described. The coronary angiograms of 300 consecutive patients with CTEPH evaluated for pulmonary thromboendarterectomy (PTE) between January 1, 2007, and May 1, 2014, were examined. Of these patients, 259 (50% male; mean age, 58.3 ± 10.6 years) had cineangiographic images deemed adequate to definitively assess for the presence of coronary artery-pulmonary artery collaterals and were included in the final analyses. Pulmonary angiogram reports were reviewed for extent of pulmonary artery obstruction. The coronary angiograms of 259 age- and sex-matched control patients were also examined. Among 259 CTEPH patients with definitive imaging, 34 coronary artery-pulmonary artery collaterals were found in 28 patients (10.8%), versus 1 coronary artery-pulmonary artery collateral among control subjects (0.4%; P < 0.001). Compared with CTEPH patients without collaterals, patients with collaterals had a significantly higher prevalence of total occlusion of their right or left main pulmonary artery (P < 0.001) or lobar arteries (P < 0.001). In conclusion, the prevalence of coronary artery-pulmonary artery collaterals in CTEPH patients undergoing coronary angiography for possible PTE is approximately 11%. These vessels are associated with more severe pulmonary artery occlusion. PMID:26064456

    Objective Lipoprotein-associated phospholipase A2 (Lp-PLA2) is deemed to play a role in atherosclerosis and plaque destabilization as demonstrated in animal models and in prospective clinical studies. However, most of the literature is either focused on high-risk, apparently healthy patients, or is based on cross sectional studies. Therefore, we tested the hypothesis that serum Lp-PLA2 mass and activity are useful for predicting cardiovascular (CV) events over the coronary atherosclerotic burden and conventional risk factors in high-risk coronary artery disease patients. Methods and Results In a prospective cohort study of 712 Caucasian patients, who underwent coronary angiography and measurement of both Lp-PLA2 mass and activity at baseline, we determined incident CV events at follow-up after splitting the patients into a high and a low Lp-PLA2 mass and activity groups based on ROC analysis and Youden index. Kaplan-Meier and propensity score matching analysis were used to compare CV event-free survival between groups. Follow-up data were obtained in 75% of the cohort after a median of 7.2 years (range 1–12.7 years) during which 129 (25.5%) CV events were observed. The high Lp-PLA2 activity patients showed worse CV event-free survival (66.7% vs. 79.5%, p = 0.023) and acute coronary syndrome-free survival (75.4% vs. 85.6%, p = 0.04) than those in low Lp-PLA2 group. Conclusions A high Lp-PLA2 activity implies a worse CV prognosis at long term follow up in high-risk Caucasian patients referred for coronary angiography. PMID:23118945

    Purpose Cardiopulmonary resuscitation (CPR) is commonly performed in high-risk, high intensity situations and is therefore a good procedure around which to develop and implement safety culture strategies in the hospital. The purpose of this study was to evaluate the impact of a hospital-wide quality improvement program on the management of sudden cardiac arrests by assessing healthcare providers' attitudes towards patient safety. Materials and Methods This study was designed as a prospective cohort study at a single academic medical center. The comprehensive hospital-based safety program included steps to identify areas of hazard, partner units with the Resuscitation Committee, and to conduct a Safety Attitudes Questionnaire (SAQ). The SAQ evaluated 35 questions in seven domains to assess changes in patient safety culture by comparing the results before and after the hospital-wide high risk patient care improvement program. Results The response rates of the pre- and post-SAQ survey were 489 out of 1121 (43.6%) and 575 out of 1270 (45.3%), respectively. SAQ survey responses revealed significant improvement in all seven domains of the questionnaire (p-values of 0.006 and lower). In a subgroup analysis, doctors and nurses showed improvement in five domains. Both doctors and nurses did not show improvement in the "sharing information" domain. Conclusion A hospital-wide quality improvement program for high-risk, high reliability patient care involving CPR care was shown to be associated with a change in healthcare providers' attitudes towards patient safety. Through an immersive and active program on CPR care, change in healthcare providers' attitudes towards patient safety was initiated. PMID:24532527

    Abstract Self-foot care is key in preventing morbidity in high-risk diabetic patients. Motivational interviewing (MI) is an approach to encouraging behavioral change by patients that can be utilized in medical settings. Our goal was to explore how podiatrists promote self-care in such patients and if they use MI techniques. A 19 question online survey of US-based practicing podiatrists. Most answers were on a 5 point scale. MI index was the sum of answers to 5 relevant questions. Of 843 podiatrists, 86% considered foot self-care to be very important for high-risk diabetic patients and 90% felt it was their role to discuss self-foot care with them; 49% felt that they had training and were successful in promoting behavioral change, but the majority were definitely (38%) or possibly (46%) interested in learning more. Only 24% scored >15 / 20 on the MI index. Higher MI scores were associated with more face time and more time discussing foot self-care, but were not related to the podiatrist's age, gender, geographic location, % time in surgery, or years in practice. Reported barriers to counseling were lack of reimbursed time and poor patient engagement. Most podiatrists view self-care behavior among high-risk diabetic patients and their role in promoting it as very important; most feel already proficient but only a minority demonstrate MI skills; fortunately the majority are willing to learn more. Success in behavioral counseling, such as MI, is likely to require more time and may be encouraged by a move from fee-for-service to outcome based reimbursement. PMID:24964268

    This study assessed arthrodesis procedures performed in the foot and ankle of high-risk patients following implantation of an internal electrical bone stimulator. Criteria defining patients as "high risk" included diabetes, obesity, habitual tobacco and/or alcohol use, immunosuppressive therapy, and previous history of nonunion. Standard arthrodesis protocol of bone graft and internal fixation was supplemented with the implantable electrical bone stimulator. A retrospective, multicenter review was conducted of 26 patients (28 cases) who underwent 28 forefoot and hindfoot arthrodeses from 1998 to 2002. Complete fusion was defined as bony trabeculation across the joint, lack of motion across the joint, maintenance of hardware/fixation, and absence of radiographic signs of nonunion or pseudoarthrosis. Radiographic consolidation was achieved in 24 of the 28 cases at an average 10.3+/-4.0 weeks. Followup averaged 27.2 months. Complications included 2 patients who sustained breakage of the cables to the bone stimulator. Five patients underwent additional surgery. Four of the 5 patients had additional surgery in order to achieve arthrodesis. All 4 went on to subsequent arthrodesis. This study demonstrates how arthrodesis of the foot and ankle may be enhanced by the use of implantable electrical bone stimulation. PMID:16257674

    Pulmonary rehabilitation programs are aimed at providing benefits to COPD patients, in various aspects. Our objective was to review the literature on COPD patient rehabilitation. This systematic review involved articles written in English, Spanish, or Portuguese; published between 2005 and 2009; and indexed in national and international databases. Articles were classified in accordance with the Global Initiative for Chronic Obstructive Lung Disease criteria for the determination of the level of scientific evidence (grade of recommendation A, B, or C). The outcome measures were exercise, quality of life, symptoms, exacerbations, mortality, and pulmonary function. Treatments were classified as standard rehabilitation, partial rehabilitation, strength exercises, and resistance exercises. Of the 40 articles selected, 4, 18, and 18 were classified as grades A, B, and C, respectively. Of the 181 analyses made in these articles, 61, 50, 23, 23, 20, and 4, respectively, were related to the outcome measures quality of life, exercise, symptoms, exacerbations, pulmonary function, and mortality. The standard rehabilitation programs showed positive effects on all of the outcomes evaluated, except for mortality (because of the small number of analyses). However, we found no differences among the various rehabilitation programs regarding their effects on the outcomes studied. Rehabilitation programs can be considered important tools for the treatment of COPD. Therefore, health administrators should implement public policies including such programs in the routine of health care facilities. PMID:21881745

    We present a case of an idiopathic pulmonary artery aneurysm in an asymptomatic patient who was treated for an irrelevant medical condition. Pulmonary artery aneurysms (PAA) are quite rare and can either be congenital or acquired. Congenital aneurysms are usually associated with cardiac malformations leading to pulmonary hypertension. Acquired aneurysms can be idiopathic or associated with infections (tuberculosis, syphilis), trauma, pulmonary valvular stenosis, or collagen diseases. Pulmonary artery aneurysms are not common and an idiopathic pulmonary artery aneurysm is a rare finding that could be diagnosed incidentally. PMID:22145274

    We reported 25 cases of patients with pulmonary embolism (PE) definitely diagnosed in our hospital from 1983 to 1990. Twenty-one cases of them were found in the last 5 years. This indicated that the discovery rate had increased obviously. Five of these patients were confirmed by autopsy, the other twenty cases were diagnosed by clinical manifestations combined with perfusion-inspiration lung scans and chest roentgenogram. Due to the prompt diagnosis and the appropriate use of anticoagulants, 72% of the patients survived after treatment. We suggest that all the patients with suspected PE should take perfusion-inspiration lung scans, because this is a noninvasive and reliable method. Digital subtraction angiography is necessary for some patients. Routine chest radiography, arterial blood gas analysis, intrapulmonary shunt test, deep venography or nuclide scan of lower extremities are also useful methods for the diagnosis of PE. PMID:8112138

    2010-01-01

    Background Complex care management is seen as an approach to face the challenges of an ageing society with increasing numbers of patients with complex care needs. The Medical Research Council in the United Kingdom has proposed a framework for the development and evaluation of complex interventions that will be used to develop and evaluate a primary care-based complex care management program for chronically ill patients at high risk for future hospitalization in Germany. Methods and design We present a multi-method procedure to develop a complex care management program to implement interventions aimed at reducing potentially avoidable hospitalizations for primary care patients with type 2 diabetes mellitus, chronic obstructive pulmonary disease, or chronic heart failure and a high likelihood of hospitalization. The procedure will start with reflection about underlying precipitating factors of hospitalizations and how they may be targeted by the planned intervention (pre-clinical phase). An intervention model will then be developed (phase I) based on theory, literature, and exploratory studies (phase II). Exploratory studies are planned that entail the recruitment of 200 patients from 10 general practices. Eligible patients will be identified using two ways of 'case finding': software based predictive modelling and physicians' proposal of patients based on clinical experience. The resulting subpopulations will be compared regarding healthcare utilization, care needs and resources using insurance claims data, a patient survey, and chart review. Qualitative studies with healthcare professionals and patients will be undertaken to identify potential barriers and enablers for optimal performance of the complex care management program. Discussion This multi-method procedure will support the development of a primary care-based care management program enabling the implementation of interventions that will potentially reduce avoidable hospitalizations.

    Purpose: To map the location of metastatic supraclavicular (SCV) lymph nodes (LNMs) in breast cancer patients with SCV node involvement and determine whether and where the radiation therapy clinical target volume (CTV) of this region could be modified in high-risk subsets. Methods and Materials: Fifty-five patients with metastatic SCV LNMs were eligible for geographic mapping and atlas coverage analysis. All LNMs and their epicenters were registered proportionally by referencing the surrounding landmarks onto simulation computed tomography images of a standard patient. CTVs based on selected SCV atlases, including the one by the Radiation Therapy Oncology Group (RTOG) were contoured. A modified SCV CTV was tried and shown to have better involved-node coverage and thus theoretically improved prophylaxis in this setting. Results: A total of 50 (91%) and 45 (81.8%) patients had LNMs in the medial and lateral SCV subregions, respectively. Also, 36 patients (65.5%) had LNMs located at the junction of the jugular-subclavian veins. All nodes were covered in only 25.5% to 41.8% of patients by different atlases. The RTOG atlas covered all nodes in 25.5% of patients. Stratified by the nodes in all the patients as a whole, 49.2% to 81.3% were covered, and the RTOG atlas covered 62.6%. The lateral and posterior borders were the most overlooked locations. Modification by extending the borders to natural anatomic barriers allowed the new CTV to cover all the nodes in 81.8% of patients and encompass 96.1% of all the nodes. Conclusions: According to the distribution of SCV LNMs, the extent of existing atlases might not be adequate for potential metastatic sites in certain groups of patients. The extension of the lateral and posterior CTV borders in high-risk or recurrent patients might be a reasonable approach for increasing coverage. However, additional data in more homogeneous populations with localized disease are needed before routine application.

    Two methods for predicting adult respiratory distress syndrome (ARDS) were evaluated prospectively in a group of 81 multitrauma and sepsis patients considered at clinical high risk. A popular ARDS risk-scoring method, employing discriminant analysis equations (weighted risk criteria and oxygenation characteristics), yielded a predictive accuracy of 59% and a false-negative rate of 22%. Pulmonary alveolar-capillary permeability (PACP) was determined with a radioaerosol lung-scan technique in 23 of these 81 patients, representing a statistically similar subgroup. Lung scanning achieved a predictive accuracy of 71% (after excluding patients with unilateral pulmonary contusion) and gave no false-negatives. We propose a combination of clinical risk identification and functional determination of PACP to assess a patient's risk of developing ARDS.

    Purpose/Objective(s): To determine the impact of adjuvant radiation treatment (RT) on recurrence-free survival (RFS), disease-specific survival (DSS), and overall survival (OS) in patients with high-risk 2009 International Federation of Gynecology and Obstetrics stage I-II endometrial carcinoma. Methods and Materials: We identified 382 patients with high-risk EC who underwent hysterectomy. RFS, DSS, and OS were calculated from the date of hysterectomy by use of the Kaplan-Meier method. Cox regression modeling was used to explore the risks associated with various factors on survival endpoints. Results: The median follow-up time for the study cohort was 5.4 years. The median age was 71 years. All patients underwent hysterectomy and salpingo-oophorectomy, 93% had peritoneal cytology, and 85% underwent lymphadenectomy. Patients with endometrioid histology constituted 72% of the study cohort, serous in 16%, clear cell in 7%, and mixed histology in 4%. Twenty-three percent of patients had stage II disease. Adjuvant management included RT alone in 220 patients (57%), chemotherapy alone in 25 patients (7%), and chemoradiation therapy in 27 patients (7%); 110 patients (29%) were treated with close surveillance. The 5-year RFS, DSS, and OS were 76%, 88%, and 73%, respectively. On multivariate analysis, adjuvant RT was a significant predictor of RFS (P<.001) DSS (P<.001), and OS (P=.017). Lymphovascular space involvement was a significant predictor of RFS and DSS (P<.001). High tumor grade was a significant predictor for RFS (P=.038) and DSS (P=.025). Involvement of the lower uterine segment was also a predictor of RFS (P=.049). Age at diagnosis and lymphovascular space involvement were significant predictors of OS: P<.001 and P=.002, respectively. Conclusion: In the treatment of patients with high-risk features, our study suggests that adjuvant RT significantly improves recurrence-free, disease-specific, and overall survival in patients with early-stage endometrial carcinoma

    Hepatocellular Carcinoma is a major healthcare problem, representing the third most common cause of cancer-related mortality worldwide. There are 130 million Hepatitis C virus infected patients worldwide who are at a high-risk for developing Hepatocellular Carcinoma. Due to the fact that reliable parameters and/or tools for the early detection of Hepatocellular Carcinoma among high-risk individuals are severely lacking, Hepatocellular Carcinoma patients are always diagnosed at a late stage where surgical solutions or effective treatment are not possible. Urine was collected from 106 Hepatitis C infected patients patients, 32 of whom had already developed Hepatocellular Carcinoma and 74 patients who were diagnosed as Hepatocellular Carcinoma -free at the time of initial sample collection. In addition to these patients, urine samples were also collected from 12 healthy control individuals. Total urinary proteins were isolated from the urine samples and LC-MS/MS was used to identify potential protein HCC biomarker candidates. This was followed by validating relative expression levels of proteins present in urine among all the patients using quantitative real time-PCR. This approach revealed that significant over-expression of three proteins: DJ-1, Chromatin Assembly Factor-1 (CAF-1) and Heat Shock Protein 60 (HSP60), was a characteristic event among Hepatocellular Carcinoma - post Hepatitis C virus infected patients. As a single-based Hepatocellular Carcinoma biomarker, CAF-1 over-expression identified Hepatocellular Carcinoma among Hepatitis C virus infected patients with a specificity of 90%, sensitivity of 66% and with an overall diagnostic accuracy of 78%. Moreover, the CAF-1/HSP60 tandem identified Hepatocellular Carcinoma among Hepatitis C virus infected patients with a specificity of 92%, sensitivity of 61% and with an overall diagnostic accuracy of 77%.

    Background and Aims: Post-operative nausea and vomiting (PONV) has an 80% incidence in high-risk patients. This is despite the availability of several antiemetic drugs. Selective 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists are considered first-line for prophylaxis, ondansetron being the most commonly used agent. Ramosetron, another selective 5-HT3 receptor antagonist, is more potent and longer acting than ondansetron. This study was conducted to evaluate the antiemetic efficacy of ramosetron in comparison with ondansetron in patients at a high risk of PONV. Methods: This was a prospective randomised double-blind study carried out over a 6-month period in which 206 patients with at least two risk factors for PONV were randomised to receive ramosetron 0.3 mg or ondansetron 8 mg, 30 min before the end of surgery. The incidence of PONV, severity of nausea and need for rescue antiemetic were recorded over the next 24 h. Primary outcome was the incidence of PONV. Secondary outcomes included severity of nausea and need for rescue. The data were analysed using the Predictive Analytics Software (PASW, version 18: Chicago, IL, USA). Results: The incidence of PONV was found to be 35% in the ramosetron group as opposed to 43.7% in the ondansetron group (P = 0.199). Need for rescue antiemetic was 23.3% in the ramosetron group and 32% in the ondansetron group (P = 0.156) in the 24 h following surgery. Conclusion: Ramosetron 0.3 mg and ondansetron 8 mg were equally effective in reducing the incidence of PONV in high risk patients. PMID:25937648

    Purpose: To evaluate genitourinary (GU) and gastrointestinal (GI) morbidity and biochemical control of disease in patients with localized prostate adenocarcinoma treated with escalating doses per fraction of high-dose rate brachytherapy alone. Methods and Materials: A total of 197 patients were treated with 34 Gy in four fractions, 36 Gy in four fractions, 31.5 Gy in three fractions, or 26 Gy in two fractions. Median follow-up times were 60, 54, 36, and 6 months, respectively. Results: Incidence of early Grade {>=} 3 GU morbidity was 3% to 7%, and Grade 4 was 0% to 4%. During the first 12 weeks, the highest mean International Prostate Symptom Score (IPSS) value was 14, and between 6 months and 5 years it was 8. Grade 3 or 4 early GI morbidity was not observed. The 3-year actuarial rate of Grade 3 GU was 3% to 16%, and was 3% to 7% for strictures requiring surgery (4-year rate). An incidence of 1% Grade 3 GI events was seen at 3 years. Late Grade 4 GU or GI events were not observed. At 3 years, 99% of patients with intermediate-risk and 91% with high-risk disease were free of biochemical relapse (log-rank p = 0.02). Conclusions: There was no significant difference in urinary and rectal morbidity between schedules. Biochemical control of disease in patients with intermediate and high risk of relapse was good.

    Background. Endoscopic retrograde cholangiopancreatography (ERCP) is an established treatment modality for bile duct disorders, but patients have a risk of post-ERCP pancreatitis (PEP) and biliary sepsis. Aim. To evaluate the effectiveness and safety of pancreatic stent for prophylaxis of PEP and biliary sepsis in high-risk patients with complicating common bile duct (CBD) disorders. Methods. Two hundred and six patients with complicating confirmed or suspected CBD disorders were randomly assigned to receive ERCP with pancreatic stenting (experimental group) or without stenting (control group). Primary outcome measure was frequency of PEP, and secondary outcome measures included operative time, blood loss, postoperative recovery times, and other ERCP-associated morbidities. Results. Baseline age, sex, CBD etiology, concomitant medical/surgical conditions, cannulation difficulty, and ERCP success were comparable between the two groups (all P > 0.05). Compared to the control group, the experimental group had a significantly lower frequency of PEP (7.7% versus 17.7%, P < 0.05) and positive bile microbial culture (40.4% versus 62.7%, P < 0.05). However, the two groups were similar in operative time, blood loss, postoperative recovery times, and other ERCP-associated morbidities (all P > 0.05). Conclusions. Pancreatic stenting can reduce the occurrence of PEP and biliary sepsis in high-risk patients with complicating CBD disorders but does not increase other ERCP-associated morbidities. This trial is registered with the Chinese Clinical Trial Registry (registration identifier ChiCTR-OCH-14005134). PMID:27057161

    At present, traditional risk factors are used to guide cardiovascular management of asymptomatic subjects. Intensified surveillance may be warranted in those identified as high risk of developing cardiovascular disease (CVD). This study aims to determine the prognostic value of coronary computed tomography (CT) angiography (CCTA) next to the coronary artery calcium score (CACS) in patients at high CVD risk without symptoms suspect for coronary artery disease (CAD). A total of 665 patients at high risk (mean age 56 ± 9 years, 417 men), having at least one important CVD risk factor (diabetes mellitus, familial hypercholesterolemia, peripheral artery disease, or severe hypertension) or a calculated European systematic coronary risk evaluation of >10% were included from outpatient clinics at 2 academic centers. Follow-up was performed for the occurrence of adverse events including all-cause mortality, nonfatal myocardial infarction, unstable angina, or coronary revascularization. During a median follow-up of 3.0 (interquartile range 1.3 to 4.1) years, adverse events occurred in 40 subjects (6.0%). By multivariate analysis, adjusted for age, gender, and CACS, obstructive CAD on CCTA (≥50% luminal stenosis) was a significant predictor of adverse events (hazard ratio 5.9 [CI 1.3 to 26.1]). Addition of CCTA to age, gender, plus CACS, increased the C statistic from 0.81 to 0.84 and resulted in a total net reclassification index of 0.19 (p <0.01). In conclusion, CCTA has incremental prognostic value and risk reclassification benefit beyond CACS in patients without CAD symptoms but with high risk of developing CVD. PMID:26754124

    Introduction Nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently associated with community-acquired acute kidney injury (AKI), a strong risk factor for development and progression of chronic kidney disease. Using access to prescription medication profiles, pharmacists can identify patients at high risk for NSAID-induced AKI. The primary objective of this analysis was to evaluate the effectiveness of a community pharmacy–based patient education program on patient knowledge of NSAID-associated renal safety concerns. Methods Patients receiving prescription medications for hypertension or diabetes mellitus were invited to participate in an educational program on the risks of NSAID use. A patient knowledge questionnaire (PKQ) consisting of 5 questions scored from 1 to 5 was completed before and after the intervention. Information was collected on age, race, sex, and frequency of NSAID use. Results A total of 152 participants (60% women) completed both the pre- and post-intervention questionnaire; average age was 54.6 (standard deviation [SD], 17.5). Mean pre-intervention PKQ score was 3.3 (SD, 1.4), and post-intervention score was 4.6 (SD, 0.9) (P = .002). Participants rated program usefulness (1 = not useful to 5 = extremely useful) as 4.2 (SD, 1.0). In addition, 48% reported current NSAID use and 67% reported that the program encouraged them to limit their use. Conclusion NSAID use was common among patients at high risk for AKI. A brief educational intervention in a community pharmacy improved patient knowledge on NSAID-associated risks. Pharmacists practicing in the community can partner with primary care providers in the medical home model to educate patients at risk for AKI. PMID:25523351

    Purpose: To report acute toxicity resulting from radiotherapy (RT) dose escalation and hypofractionation using intensity-modulated RT (IMRT) treatment combined with androgen suppression in high-risk prostate cancer patients. Methods and Materials: Sixty patients with a histological diagnosis of high-risk prostatic adenocarcinoma (having either a clinical Stage of >=T3a or an initial prostate-specific antigen [PSA] level of >=20 ng/ml or a Gleason score of 8 to 10 or a combination of a PSA concentration of >15 ng/ml and a Gleason score of 7) were enrolled. RT prescription was 68 Gy in 25 fractions (2.72 Gy/fraction) over 5 weeks to the prostate and proximal seminal vesicles. The pelvic lymph nodes and distal seminal vesicles concurrently received 45 Gy in 25 fractions. The patients were treated with helical TomoTherapy-based IMRT and underwent daily megavoltage CT image-guided verification prior to each treatment. Acute toxicity scores were recorded weekly during RT and at 3 months post-RT, using Radiation Therapy Oncology Group acute toxicity scales. Results: All patients completed RT and follow up for 3 months. The maximum acute toxicity scores were as follows: 21 (35%) patients had Grade 2 gastrointestinal (GI) toxicity; 4 (6.67%) patients had Grade 3 genitourinary (GU) toxicity; and 30 (33.33%) patients had Grade 2 GU toxicity. These toxicity scores were reduced after RT; there were only 8 (13.6%) patients with Grade 1 GI toxicity, 11 (18.97%) with Grade 1 GU toxicity, and 5 (8.62%) with Grade 2 GU toxicity at 3 months follow up. Only the V60 to the rectum correlated with the GI toxicity. Conclusion: Dose escalation using a hypofractionated schedule to the prostate with concurrent pelvic lymph node RT and long-term androgen suppression therapy is well tolerated acutely. Longer follow up for outcome and late toxicity is required.

    Systemic scedosporiasis due to the anamorph or asexual form Scedosporium apiospermum (Pseudallescheria boydii) has become an important cause of opportunistic mycosis, especially in patients undergoing high-risk hematopoietic stem cell transplantation. We report a case of rapidly progressive cerebellar hyalohyphomycosis due to Scedosporium apiospermum in an allogeneic marrow graft recipient receiving treatment for severe graft-versus-host disease. This fatal breakthrough intracranial abscess, due to amphotericin B-resistant (minimum inhibitory concentration > 16 micro g/ml) mold, developed during the course of systemic antifungal therapy given for multicentric pulmonary aspergillosis. Despite treatment with high-dose Abelcet (10 mg/kg daily), free amphotericin B was not detected in postmortem cerebellar tissue. A broad-spectrum triazole-based agent (voriconazole/UK-109, 496--Vfend), and a novel fungal cell wall inhibitor, an echinocandin/pneumocandin analog (caspofungin/MK-0991--Cancidas), which exhibit excellent in vitro activity against most clinical Pseudallescheria boydii-Scedosporium apiospermum isolates, have recently become available in the United States and may provide much needed treatment options for patients at risk.

    Background Clinical outcomes of the drug-coated balloon (DCB) procedure in high-risk patients with femoropopliteal (FP) disease have not been investigated sufficiently. Methods This retrospective, single-center study analyzed 87 patients (39% dialysis) and 97 affected legs (64% critical limb ischemia [CLI]) that underwent DCB for symptomatic FP disease from March 2013 to September 2014. Risk stratification was based on FeDCLIP (female, diabetes, dialysis, CLI, lesion length >150 mm and poor runoff) score. The DCB outcomes among the different risk groups were compared and factors predicting restenosis were analyzed during follow-up. Results Most of study participants (84%) were moderate to high-risk patients. The procedural success rate was 100% and the 30-day major adverse vascular event rate was 2.1%. The mean lesion length was 178 ± 106 mm and the mean follow-up time was 428 ± 145 (range 50–782) days. The binary restenosis-free and clinically driven target lesion revascularization (CD-TLR)-free rates at 12 months were 77.5% and 84.3%, respectively, for all participants. No significant differences were observed in 1-year binary restenosis and CD-TLR rates in the low-, moderate-, and high-risk groups (60%, 84%, and 73%: p = 0.396; 78%, 89%, and 80%: p = 0.635, respectively). In multivariate analysis, lesion length >150 mm (Hazard ratio [HR]: 8.00, 95% confidence interval (CI) 1.12 to 55.6, p = 0.038) and Rutherford class 6 (HR: 7.09, 95% CI, 1.15 to 43.5, p = 0.034) were identified as independent predictors of binary restenosis. Conclusions Despite general comorbidities and advanced limb ischemia, 1-year outcomes of DCB in high-risk patients with FP disease were effective. The DCB procedure holds promise to improve vessel patency; however, lesion length >150 mm and major tissue loss were independent predictors for binary restenosis after the treatment. PMID:26599128

    Presence of autoantibodies precedes development of seropositive rheumatoid arthritis (SP RA) and seropositive arthralgia patients (SAP) are at risk of developing RA. The aims of the study are to identify additional serum immune markers discriminating between SP and seronegative (SN) RA, and markers identifying high-risk SAP. Sera from SAP (n = 27), SP RA (n = 22), SN RA (n = 11) and healthy controls (n = 20) were analyzed using the Human Cytokine 25-Plex Panel. Selected markers were validated in independent cohorts of SP RA (n = 35) and SN RA (n = 12) patients. Eleven of 27 SAP developed RA within 8 months (median follow-up time, range 1–32 months), and their baseline serum markers were compared to 16 non-progressing SAP. SAP and SP RA patients showed a marked overlap in their systemic immune profiles, while SN RA showed a distinct immune profile. Three of 4 markers discriminating between SP and SN RA (IL-1β, IL-15 and Eotaxin, but not CCL5) were similarly modulated in independent cohorts. SAP progressing to RA showed trends for increases in IL-5, MIP-1β, IL-1RA and IL-12 compared to non-progressing SAP. ROC analysis showed that serum IL-5 most accurately discriminated between the two SAP groups (AUC > 0.8), suggesting that baseline IL-5 levels may aid the identification of high-risk SAP.

    We describe two hemodialysis patients with high-risk myelodysplastic syndrome (MDS) treated with azacitidine. A 65-year-old woman (case 1) received azacitidine at 75 mg/m(2) for 7 days, and a 52-year-old man (case 2) with liver cirrhosis received a 70% dose of azacitidine. Both cases developed grade 4 cytopenia, but they achieved transfusion independence after 3 and 2 courses, and the durations of remission were 10 and 11 months, respectively. Case 1 had the complication of febrile neutropenia (FN) twice during the 1(st) and 2(nd) courses, but continued to receive azacitidine treatment thereafter. Case 2 developed infectious peritonitis during the sixth course, and azacitidine treatment was thus discontinued. After a 4-month treatment interruption, he became transfusion-dependent, and re-induction of azacitidine was successful. Of note, the course of case 1 was complicated by erythema nodosum on admission, which then disappeared after one course of azacitidine treatment. The mean durations of hospitalization were 17.5 and 23 days per course of azacitidine treatment, respectively. Though there are few reports of azacitidine treatment for hemodialysis patients with high-risk MDS, we advocate administering azacitidine to such patients, while paying close attention to the dose intensity of azacitidine and taking prompt action to manage infectious complications.

    Lung cancer and chronic obstructive pulmonary disease (COPD) are two intimately related diseases, with great impact on public health. Annual screening using low-dose computed tomography (LDCT) of the chest significantly reduces mortality due to lung cancer, and several scientific societies now recommend this technique. COPD, defined by the presence of airflow obstruction [forced expiratory volume and forced vital capacity (FVC) ratio less than 0.70], and their clinical phenotypes, namely emphysema and chronic bronchitis, have been associated with increased lung cancer risk. Several epidemiological studies, including lung cancer screening trials, have found a 2- to 4-fold increase in lung cancer risk in patients with COPD when compared to individuals without airflow obstruction. Part of the risk attributed to airflow obstruction appears to be derived from the presence of radiographic emphysema. The latter has proven to be an important lung cancer risk factor in smokers without airflow obstruction and even in never smokers. This evidence supports the idea of including patients with COPD and/or emphysema in lung cancer screening programs. There is evidence that lung cancer screening in this population is effective and can potentially reduce mortality. Specific lung cancer risk scores have been developed for patients with COPD [COPD lung cancer screening score (LUCSS) and COPD-LUCSS-diffusing capacity for carbon monoxide (DLCO)] to identify those at high risk. A multidisciplinary approach for an adequate patient selection, especially of patients with severe disease, is key to maximize benefits and reduce harms from lung cancer screening in this population. Patients with COPD included in lung cancer screening programs could also benefit from other interventions, such as smoking cessation and adequate treatment. PMID:27195278

    Many reviews concerning pulmonary complications after cardiac surgical procedures in patients with serious pulmonary disease have been published. However, no strict pulmonary function guidelines were proposed to help the clinician identify the patients at greater risk. We considered whether a low pulmonary function became a risk factor of cardiac operations. We conducted a retrospective analysis of records of 32 patients with severely impaired preoperative pulmonary function who had undergone cardiac operations between July 1988 and March 1999. There was 1 hospital death. The over-all mortality rate was 3.1% (1 of 32). However, this death could not be directly attributed to postoperative pulmonary complications. Postoperative pulmonary complications were seen in 2 patients (6.3%) who required tracheostomy due to atelectasis and pneumonia. No late deaths due to pulmonary complications were observed during the follow-up period. The actual survival rate is 68% at 7 years. A low pulmonary function did not, by itself, become a risk factor of cardiac operations, although a pulmonary function test can be used to alert the clinician to possible postoperative complications, including the requirement of tracheostomy. Especially strict control of postoperative respiration is necessary in patients with forced expiratory volume (FEV) of 1.0 <= 800 ml and/or FEV1.0/BSA <= 600 ml/m2. PMID:10870003

  2. The challenge of individualised risk assessment and therapy planning in elderly high-risk myelodysplastic syndromes (MDS) patients.

    Myelodysplastic syndromes (MDS) represent one of the most frequent and serious haematologic diseases of the elderly. Effective therapies exist ranging from best supportive care to haematologic stem cell transplantation (HSCT). Decision making, however, is rather complex in this group of patients because ageing is a multidimensional process involving not only physiological changes but also changes in functional, social, emotional and cognitive capacities. All these factors can have a significant impact on the efficacy and tolerability of a potential therapy and therefore have to be thoroughly assessed before deciding on individual treatment regimens. Risk assessment tools are available both to classify the stage and prognosis of MDS and to meet the needs of elderly patients. A tool explicitly focussing on elderly MDS patients, however, is still missing. The current report approached this issue by combining the well established MDS-risk score 'International Prognostic Scoring System' (IPSS) with the 'Multidimensional Geriatric Assessment' (MGA). As decision making is most complex in high-risk MDS patients, the new algorithm is presented exemplarily for this group of patients. In a first step, MDS-related risk is identified using IPSS, in a second step, patients are assigned to one of three risk categories of the MGA (go-go/fit, slow-go/vulnerable, no-go/frail). While go-go patients might be subjected to therapies comparable to those given to younger patients, in no-go patients, a palliative therapy combined with best supportive care will probably be most appropriate. In slow-go patients, age-related life expectancy taken from public age statistics should be compared to the MDS-related life expectancy. Based on this combined assessment procedure and also on treatment tolerance in terms of the expectations/wishes of the patient and his/her family, an individualised therapeutic approach should be developed. Specific treatment recommendations for these three groups of

    Acute pulmonary embolism is an important differential diagnosis of acute chest pain. The clinical signs are often non-specific. However, diagnosis and therapy must be done quickly in order to reduce morbidity and mortality. The new (2014) European guidelines for acute pulmonary embolism (PE) focus on risk-adapted diagnostic algorithms and prognosis adapted therapy concepts. According to the hemodynamic presentation the division in a high-risk group (unstable patient with persistent hypotension or shock) or in non-high-risk groups (hemodynamically stable) was proposed. In the high-risk group the immediate diagnosis is usually done by multidetector spiral computed tomography (MDCT) and primarily the medical therapy of right ventricular dysfunction and thrombolysis is recommended.In the non-high-risk group, this is subdivided into an intermediate-risk group and low-risk group, the diagnosis algorithm based on the PE-pretest probability--determined by validated scores. Moreover, the diagnosis is usually secured by MDCT--the new gold standard in the PE-diagnosis, scores, or it can be primarily ruled out due to the high negative predictive value of D-dimer determination. To improve the prognostic risk stratification in non-high-risk group patients the additional detection of right ventricular dysfunction (MDCT, echocardiography), cardiac biomarkers (troponin, NT proBNP) and validated scores (e.g. Pulmonary Embolism Severity Index) is recommended. Therefore, the intermediate-risk group can be further subdivided. For treatment of non-high-risk group patients, the initial anticoagulation (except those with severe renal insufficiency) using low molecular weight heparin/fondaparinux and conversion to vitamin-K antagonists or alternatively with direct oral anticoagulants (DOAK) is recommended. Hemodynamically stable patients with right ventricular dysfunction and myocardial ischemia (Intermediate-high-risk group patients) but with clinically progressive hemodynamic

    Purpose: To investigate the association between 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) and biochemical and survival outcomes after high-dose radiotherapy (RT) for prostate cancer. Methods and Materials: A total of 1711 men with clinical stage T1-T3 prostate cancer were treated with conformal RT to a median dose of 81 Gy during 1995-2007. Preradiotherapy medication data were available for 1681 patients. Three hundred eighty-two patients (23%) were taking a statin medication at diagnosis and throughout RT. Nine hundred forty-seven patients received a short-course of neoadjuvant and concurrent androgen-deprivation therapy (ADT) with RT. The median follow-up was 5.9 years. Results: The 5- and 8-year PSA relapse-free survival (PRFS) rates for statin patients were 89% and 80%, compared with 83% and 74% for those not taking statins (p = 0.002). In a multivariate analysis, statin use (hazard ratio [HR]0.69, p = 0.03), National Comprehensive Cancer Network (NCCN) low-risk group, and ADT use were associated with improved PRFS. Only high-risk patients in the statin group demonstrated improvement in PRFS (HR 0.52, p = 0.02). Across all groups, statin use was not associated with improved distant metastasis-free survival (DMFS) (p = 0.51). On multivariate analysis, lower NCCN risk group (p = 0.01) and ADT use (p = 0.005) predicted improved DMFS. Conclusions: Statin use during high-dose RT for clinically localized prostate cancer was associated with a significant improvement in PRFS in high-risk patients. These data suggest that statins have anticancer activity and possibly provide radiosensitization when used in conjunction with RT in the treatment of prostate cancer.

    Background: This study evaluated the wearable cardioverter-defibrillator (WCD) for use and effectiveness in preventing sudden death caused by ventricular tachyarrhythmia or fibrillation. Methods: From April 2010 through October 2013, 6043 German WCD patients (median age, 57 years; male, 78.5%) were recruited from 404 German centers. Deidentified German patient data were used for a retrospective, nonrandomized analysis. Results: Ninety-four patients (1.6%) were treated by the WCD in response to ventricular tachyarrhythmia/fibrillation. The incidence rate was 8.4 (95% confidence interval, 6.8–10.2) per 100 patient-years. Patients with implantable cardioverter-defibrillator explantation had an incidence rate of 19.3 (95% confidence interval, 12.2–29.0) per 100 patient-years. In contrast, an incidence rate of 8.2 (95% confidence interval, 6.4–10.3) was observed in the remaining cardiac diagnosis groups, including dilated cardiomyopathy, myocarditis, and ischemic and nonischemic cardiomyopathies. Among 120 shocked patients, 112 (93%) survived 24 hours after treatment, whereas asystole was observed in 2 patients (0.03%) with 1 resulting death. ConclusionS: This large cohort represents the first nationwide evaluation of WCD use in patients outside the US healthcare system and confirms the overall value of the WCD in German treatment pathways.

    Chronic thromboembolic pulmonary hypertension (CTEPH) is a disabling condition that is being increasingly recognised. It is unique as a cause of pulmonary hypertension in that it is surgically curable. We wish to highlight the importance of recognition and early referral of any patient who may have CTEPH even in the absence of resting pulmonary hypertension as excellent results can be achieved by restoring pulmonary vascular anatomy, reducing exercise-induced pulmonary hypertension, and reducing dead-space ventilation. We present a case that illustrates these points and discuss our experience as a referral centre for CTEPH. PMID:23133777

    Contrast-enhanced ultrasound (CEUS) plays an essential role in the evaluation of small nodules in livers at high-risk for hepatocellular carcinoma (HCC) and offers unique advantages over CT/MRI. These include the sensitive depiction of arterial hypervascularity of HCC, better demonstration of rapid washout for non-HCC malignancy as well as of very late washout of HCC. Visualization of early vascular filling patterns for benign hypervascular lesions is of indisputable value. A frequently uncounted benefit of CEUS includes the value of its performance following nodule detection at ultrasound surveillance, including one-stop exclusion of typical benignancy, preclusion of arterial pseudolesions shown on CT/MR, and the avoidance of miscorrelation of a nodule on surveillance and subsequent diagnostic imaging. Therefore, CEUS can effectively be used in the diagnostic algorithm for new liver nodules detected during HCC surveillance. Despite the fact that CEUS is actively used as a major diagnostic test for HCC in Asia, Europe, and Canada with increasing demands in clinical practice, CEUS is not included in the diagnostic tests for HCC in some major practice guidelines. In this manuscript, we focus on small nodules in patients at high-risk for HCC, and review some of the unique advantages of CEUS that contribute to lesion characterization and subsequent patient management, showing why CEUS should be an essential component of the diagnostic algorithm for HCC.

    Systemic mastocytosis (SM) is a heterogeneous disease with altered interleukin (IL)-6 and IL13 plasma levels. However, no study has simultaneously investigated the plasma levels of IL1β, IL6, IL13, CCL23 and clusterin in SM at diagnosis and correlated them with disease outcome. Here we investigated IL1β, IL6, IL13, CCL23 and clusterin plasma levels in 75 SM patients--66 indolent SM (ISM) and 9 aggressive SM--and analyzed their prognostic impact among ISM cases grouped according to the extent of hematopoietic involvement of the bone marrow cells by the KIT D816V mutation. Although increased IL1β, IL6 and CCL23 levels were detected in SM patients versus healthy controls, only IL6 and CCL23 levels gradually increased with disease severity. Moreover, increased IL6 plasma levels were associated with ISM progression to more aggressive disease, in particular among ISM patients with multilineal KIT mutation (ISM-ML), these patients also showing a higher frequency of organomegalies, versus other ISM-ML patients. Of note, all ISM patients who progressed had increased IL6 plasma levels already at diagnosis. Our results indicate that SM patients display an altered plasma cytokine profile already at diagnosis, increased IL6 plasma levels emerging as an early marker for disease progression among ISM cases, in particular among high-risk ISM patients who carry multilineage KIT mutation.

    NOTCH1 has been found recurrently mutated in a subset of patients with chronic lymphocytic leukemia (CLL). To analyze biological features and clinical impact of NOTCH1 mutations in CLL, we sequenced this gene in 565 patients. NOTCH1 mutations, found in 63 patients (11%), were associated with unmutated IGHV, high expression of CD38 and ZAP-70, trisomy 12, advanced stage and elevated lactate dehydrogenase. Sequential analysis in 200 patients demonstrated acquisition of mutation in one case (0.5%) and disappearance after treatment in two. Binet A and B patients with NOTCH1-mutated had a shorter time to treatment. NOTCH1-mutated patients were more frequently refractory to therapy and showed shorter progression-free and overall survival after complete remission. Overall survival was shorter in NOTCH1-mutated patients, although not independently from IGHV. NOTCH1 mutation increased the risk of transformation to diffuse large B-cell lymphoma independently from IGHV, with this being validated in resampling tests of replicability. In summary, NOTCH1 mutational status, that was rarely acquired during the course of the disease, identify a genetic subgroup with high risk of transformation and poor outcome. This recently identified genetic subgroup of CLL patients deserves prospective studies to define their best management. PMID:23295735

    Patients with five or more chronic conditions drive most Medicare costs. Our organization, ChenMed, developed a scalable primary care-led delivery model that focuses on this population while getting reimbursed through full-risk capitation by Medicare Advantage plans. ChenMed is a primary care-led group practice based in Florida that serves low-to-moderate-income elderly patients, largely through the Medicare Advantage program. Our model includes a number of innovations: a one-stop-shop approach for delivering multispecialty services in the community, smaller physician panel sizes of 350-450 patients that allow for intensive health coaching and preventive care, on-site physician pharmacy dispensing, a collaborative physician culture with peer review, and customized information technology. These innovations have improved patient medication adherence, increased the time doctors and patients spend together, and led to high rates of patient satisfaction. Additionally, our Medicare patients have substantially lower rates of hospital use than their peers in the Miami Medicare market. Creating chronic disease centers focused on seniors with multiple chronic conditions is a promising delivery system innovation with major potential to improve the cost and quality of care.

    Purpose To examine the association between pre–radiation therapy (RT) fluorine 18 fluorodeoxyglucose (FDG) uptake and post-RT symptomatic radiation pneumonitis (RP). Materials and Methods In accordance with the retrospective study protocol approved by the institutional review board, 228 esophageal cancer patients who underwent FDG PET/CT before chemotherapy and RT were examined. RP symptoms were evaluated by using the Common Terminology Criteria for Adverse Events, version 4.0, from the consensus of five clinicians. By using the cumulative distribution of standardized uptake values (SUVs) within the lungs, those values greater than 80%–95% of the total lung voxels were determined for each patient. The effect of pre-chemotherapy and RT FDG uptake, dose, and patient or treatment characteristics on RP toxicity was studied by using logistic regression. Results The study subjects were treated with three-dimensional conformal RT (n = 36), intensity-modulated RT (n = 135), or proton therapy (n = 57). Logistic regression analysis demonstrated elevated FDG uptake at pre-chemotherapy and RT was related to expression of RP symptoms. Study subjects with elevated 95% percentile of the SUV (SUV95) were more likely to develop symptomatic RP (P .000012); each 0.1 unit increase in SUV95 was associated with a 1.36-fold increase in the odds of symptomatic RP. Receiver operating characteristic (ROC) curve analysis resulted in area under the ROC curve of 0.676 (95% confidence interval: 0.58, 0.77), sensitivity of 60%, and specificity of 71% at the 1.17 SUV95 threshold. CT imaging and dosimetric parameters were found to be poor predictors of RP symptoms. Conclusion The SUV95, a biomarker of pretreatment pulmonary metabolic activity, was shown to be prognostic of symptomatic RP. Elevation in this pretreatment biomarker identifies patients at high risk for posttreatment symptomatic RP. PMID:25584706

    Adult sporadic Burkitt lymphoma (BL) is a rare subtype of lymphoma. In this retrospective study, we investigated the prognostic value of pretreatment lymphocyte to monocyte ratio (LMR) in a cohort of 62 patients. Using LMR <2.6 as the optimal cutoff point, 24 patients (38.7 %) had LMR <2.6. The complete response rates in high-LMR group and low-LMR group were 90.9 and 65.0 %, respectively (P = 0.019). At a median follow-up time of 41 months, the 3-year progression-free survival (PFS) rate and overall survival (OS) rates were 76 and 80 %, respectively. In a multivariate Cox regression model, it was found that the presence of bone marrow infiltration and low LMR were independently adverse prognostic factors for both PFS and OS. In the whole group, the addition of rituximab to treatment did not benefit patients significantly in PFS and OS. In subgroup analysis, in patients with high LMR, addition of rituximab can significantly improve survival outcomes (P = 0.046). In conclusion, we firstly found that low LMR (<2.60) was an independently adverse prognostic factor in adult patients with sporadic BL. Intensive chemotherapy could cure the majority of patients in our study, and the pretreatment LMR might predict the value of rituximab in this age population. PMID:26082333

    Serum antibodies to Giardia lamblia were measured in giardiasis patients, in groups at high risk for intestinal parasite infection, and in controls by an indirect fluorescent antibody (IFA) technique. Symptomatic patients had the highest antibody titers, and antibodies remained present for up to 18 months in persons with chronic infection. Indochinese refugees and male homosexuals with the acquired immunodeficiency syndrome (AIDS) and pre-AIDS had higher mean antibody levels than did healthy controls, whereas sewer and highway maintenance workers had levels similar to those of controls. Serum antibodies to Entamoeba histolytica measured by an indirect hemagglutination antibody technique were detected in only a few Indochinese refugees. We conclude that serology is a promising tool in G. lamblia epidemiology and that further population studies would be of interest. PMID:2886069

    Purpose: To present a large experience (73 patients) using a standard radiotherapy (RT) protocol to prevent relapse in cranial sites where measurable metastatic neuroblastoma (NB), an adverse prognostic marker, is common. Methods and Materials: High-risk NB patients with measurable cranial disease at diagnosis or residual cranial disease after induction therapy had those sites irradiated with hyperfractionated 21 Gy; a brain-sparing technique was used for an extensive field. The patients were grouped according to the response to systemic therapy. Thus, when irradiated, Group 1 patients were in complete remission and Group 2 patients had primary refractory disease. Follow-up was from the start of cranial RT. Results: At 3 years, the 39 Group 1 patients had a progression-free survival rate of 51%; control of cranial disease was 79%. Two relapses involved irradiated cranial sites. Two other patients relapsed in the irradiated cranial sites 6 and 12 months after a systemic relapse. At 3 years, the 34 Group 2 patients had a progression-free survival rate of 33%; control of cranial disease was 52%. Group 2 included 19 patients who had residual cranial (with or without extracranial) disease. The cranial sites showed major (n = 13), minor (n = 2), or no response (n = 4) to RT. Five patients had progression in the cranial RT field at 10-27 months. Group 2 also included 15 patients who had persistent NB in extracranial, but not cranial, sites. Of these 15 patients, 2 relapsed in the irradiated cranial sites and elsewhere at 8 and 14 months. Cranial RT was well tolerated, with no Grade 2 or greater toxicity. Conclusion: Hyperfractionated 21-Gy cranial RT might help control NB and is feasible without significant toxicity in children.

  17. First experience with a new negative pressure incision management system on surgical incisions after cardiac surgery in high risk patients

    2011-01-01

    Background Sternal wound infection remains a serious potential complication after cardiac surgery. A recent development for preventing wound complications after surgery is the adjunctive treatment of closed incisions with negative pressure wound therapy. Suggested mechanisms of preventive action are improving the local blood flow, removing fluids and components in these fluids, helping keep the incision edges together, protecting the wound from external contamination and promoting incision healing. This work reports on our initial evaluation and clinical experience with the Prevena™Incision Management System, a recently introduced new negative pressure wound therapy system specifically developed for treating closed surgical incisions and helping prevent potential complications. We evaluated the new treatment on sternal surgical incisions in patients with multiple co-morbidities and consequently a high risk for wound complications. Methods The Prevena™incision management system was used in 10 patients with a mean Fowler risk score of 15.1 [Range 8-30]. The negative pressure dressing was applied immediately after surgery and left in place for 5 days with a continuous application of -125 mmHg negative pressure. Wounds and surrounding skin were inspected immediately after removal of the Prevena™ incision management system and at day 30 after surgery. Results Wounds and surrounding skin showed complete wound healing with the absence of skin lesions due to the negative pressure after removal of the Prevena™ dressing. No device-related complications were observed. No wound complications occurred in this high risk group of patients until at least 30 days after surgery. Conclusions The Prevena™system appears to be safe, easy to use and may help achieve uncomplicated wound healing in patients at risk of developing wound complications after cardiothoracic surgery.

    Purpose: To compare the toxicity and efficacy of hypofractionated (62 Gy/20 fractions/5 weeks, 4 fractions per week) vs. conventional fractionation radiotherapy (80 Gy/40 fractions/8 weeks) in patients with high-risk prostate cancer. Methods and Materials: From January 2003 to December 2007, 168 patients were randomized to receive either hypofractionated or conventional fractionated schedules of three-dimensional conformal radiotherapy to the prostate and seminal vesicles. All patients received a 9-month course of total androgen deprivation (TAD), and radiotherapy started 2 months thereafter. Results: The median (range) follow-up was 32 (8-66) and 35 (7-64) months in the hypofractionation and conventional fractionation arms, respectively. No difference was found for late toxicity between the two treatment groups, with 3-year Grade 2 rates of 17% and 16% for gastrointestinal and 14% and 11% for genitourinary in the hypofractionation and conventional fractionation groups, respectively. The 3-year freedom from biochemical failure (FFBF) rates were 87% and 79% in the hypofractionation and conventional fractionation groups, respectively (p = 0.035). The 3-year FFBF rates in patients at a very high risk (i.e., pretreatment prostate-specific antigen (iPSA) >20 ng/mL, Gleason score {>=}8, or T {>=}2c), were 88% and 76% (p = 0.014) in the former and latter arm, respectively. The multivariate Cox analysis confirmed fractionation, iPSA, and Gleason score as significant prognostic factors. Conclusions: Our findings suggest that late toxicity is equivalent between the two treatment groups and that the hypofractionated schedule used in this trial is superior to the conventional fractionation in terms of FFBF.

    Abstract To analyze the association between use of DPP-4 inhibitors and acute pancreatitis in high-risk type 2 diabetic patients. A retrospective nationwide cohort study was conducted using the Taiwan National Health Insurance claim database. The risk associated with sitagliptin was compared to that with acarbose, a second-line antidiabetic drug prescribed for patients with similar diabetes severity and with a known neutral effect on pancreatitis. Between January 1, 2009 and December 31, 2010, a total of 8526 sitagliptin initiators and 8055 acarbose initiators who had hypertriglyceridemia or prior hospitalization history for acute pancreatitis were analyzed for the risk of hospitalization due to acute pancreatitis stratified for baseline propensity score. In the crude analysis, sitagliptin was associated with a decreased risk of acute pancreatitis (hazard ratio [HR] 0.74; 95% confidence interval [CI]: 0.62–0.88) compared to acarbose in diabetic patients with prior history of hospitalization for pancreatitis or hypertriglyceridemia. The association was abolished after stratification for propensity score quintiles (adjusted HR 0.95; 95% CI: 0.79–1.16). Similar results were found separately in both patients’ histories of prior hospitalization of acute pancreatitis (adjusted HR 0.97; 95% CI: 0.76–1.24) and those with hypertriglyceridemia (adjusted HR 0.86; 95% CI: 0.65–1.13). No significant association was found for different durations or accumulative doses of sitagliptin. In the stratified analysis, no significant effect modification was found in relation to patients’ characteristics. Use of sitagliptin was not associated with an increased risk of acute pancreatitis in high-risk diabetic patients with hypertriglyceridemia or with history of acute pancreatitis. PMID:26886601

    Massive pulmonary embolism is associated with mortality rates exceeding 50%. Current practice guidelines include the immediate administration of thrombolytic therapy in the absence of contraindications. However, thrombolysis for pulmonary embolism is said to be absolutely contraindicated in the presence of recent hemorrhagic stroke and other conditions. The current contraindications to thrombolytic therapy have been extrapolated from data on acute coronary syndrome and are not specific for venous thromboembolic disease. Some investigators have proposed that the current contraindications be viewed as relative, rather than absolute, in cases of high-risk pulmonary embolism. We present the case of a 60-year-old woman in whom massive pulmonary embolism led to cardiac arrest with pulseless electrical activity. Eight weeks earlier, she had sustained a hemorrhagic cerebrovascular accident-a classic absolute contraindication to thrombolytic therapy. Despite this practice guideline, we administered tissue plasminogen activator systemically in order to save the patient's life. This therapy did not evoke intracranial bleeding, and the patient was eventually discharged from the hospital. Until guidelines specific to venous thromboembolic disease are developed, we think that the current contraindications to thrombolysis should be considered on an individual basis in patients who are at high risk of death from massive pulmonary embolism.

    Here we conducted a retrospective study to examine the risk of cardiovascular events (CVEs) relative to that of end-stage renal disease (ESRD) in patients with primary membranous nephropathy, in a discovery cohort of 404 patients. The cumulative incidence of CVEs was estimated in the setting of the competing risk of ESRD with risk factors for CVEs assessed by multivariable survival analysis. The observed cumulative incidences of CVEs were 4.4%, 5.4%, 8.2%, and 8.8% at 1, 2, 3, and 5 years respectively in the primary membranous nephropathy cohort. In the first 2 years after diagnosis, the risk for CVEs was similar to that of ESRD in the entire cohort, but exceeded it among patients with preserved renal function. Accounting for traditional risk factors and renal function, the severity of nephrosis at the time of the event (hazard ratio 2.1, 95% confidence interval 1.1 to 4.3) was a significant independent risk factor of CVEs. The incidence and risk factors of CVEs were affirmed in an external validation cohort of 557 patients with primary membranous nephropathy. Thus early in the course of disease, patients with primary membranous nephropathy have an increased risk of CVEs commensurate to, or exceeding that of ESRD. Hence, reduction of CVEs should be considered as a therapeutic outcome measure and focus of intervention in primary membranous nephropathy. PMID:26924046

    Objective To assess whether non-clinical staff can effectively manage people at high risk of cardiovascular disease using digital health technologies. Design Pragmatic, multicentre, randomised controlled trial. Setting 42 general practices in three areas of England. Participants Between 3 December 2012 and 23 July 2013 we recruited 641 adults aged 40 to 74 years with a 10 year cardiovascular disease risk of 20% or more, no previous cardiovascular event, at least one modifiable risk factor (systolic blood pressure ≥140 mm Hg, body mass index ≥30, current smoker), and access to a telephone, the internet, and email. Participants were individually allocated to intervention (n=325) or control (n=316) groups using automated randomisation stratified by site, minimised by practice and baseline risk score. Interventions Intervention was the Healthlines service (alongside usual care), comprising regular telephone calls from trained lay health advisors following scripts generated by interactive software. Advisors facilitated self management by supporting participants to use online resources to reduce risk factors, and sought to optimise drug use, improve treatment adherence, and encourage healthier lifestyles. The control group comprised usual care alone. Main outcome measures The primary outcome was the proportion of participants responding to treatment, defined as maintaining or reducing their cardiovascular risk after 12 months. Outcomes were collected six and 12 months after randomisation and analysed masked. Participants were not masked. Results 50% (148/295) of participants in the intervention group responded to treatment compared with 43% (124/291) in the control group (adjusted odds ratio 1.3, 95% confidence interval 1.0 to 1.9; number needed to treat=13); a difference possibly due to chance (P=0.08). The intervention was associated with reductions in blood pressure (difference in mean systolic −2.7 mm Hg (95% confidence interval −4.7 to −0.6 mm Hg

    Thromboembolism continues to be a major concern in patients with mechanical heart valves, especially in those with unsatisfactory anticoagulation levels. The new On-X valve (On-X Life Technologies, Austin, TX, USA) has been reported as having unique structural characteristics that offer lower thrombogenicity to the valve. We report a case where the patient received no or minimal systemic anticoagulation after placement of On-X mitral and aortic valves due to development of severe mucosal arterio-venous malformations yet did not show any evidence of thromboembolism. This case report reinforces the findings of recent studies that lower anticoagulation levels may be acceptable in patients with On-X valves and suggests this valve may be particularly useful in those in whom therapeutic levels of anticoagulation cannot be achieved due to increased risk of bleeding.

    Fungal infections are the most common opportunistic infections (OI) occurring during the course of HIV infection, though their incidence has decreased dramatically with the introduction of highly active antiretroviral therapy (cART). Most cases occur in untreated patients, noncompliant patients or patients whose multiple antiretroviral regimens have failed and they are a good marker of the severity of cellular immunodepression. Pneumocystis jiroveci pneumonia is the second most frequent OI in France and cryptococcosis remains a major problem in the Southern Hemisphere. With the increase in travel, imported endemic fungal infection can occur and may mimic other infections, notably tuberculosis. Fungal infections often have a pulmonary presentation but an exhaustive search for dissemination should be made in patients infected with HIV, at least those at an advanced stage of immune deficiency. Introduction of cART in combination with anti-fungal treatment depends on the risk of AIDS progression and on the risk of cumulative toxicity and the immune reconstitution inflammatory syndrome (IRIS) if introduced too early. Fungal infections in HIV infected patients remain a problem in the cART era. IRIS can complicate the management and requires an optimised treatment regime. PMID:24182654

    Metabolic abnormalities are common in patients with depressive disorders. However, the relationship between gout and depression is unclear. We explored the causal relationship among gout, antigout medication, and the associated risk of incidental depressive disorders.In this nationwide cohort study, we sampled data from the National Health Insurance Research Database to recruit 34,050 patients with gout as the gout cohort and 68,100 controls (without gout) as the nongout cohort. Our primary endpoint was the diagnosis of depressive disorders during follow-up. The overall study population was followed up until depression diagnosis, withdrawal from the NHI program, or the end of the study. The differences in demographic and clinical characteristics between both cohorts were determined using the Chi-square test for categorical variables and the t-test for continuous variables. Cox proportional hazard regression models were used to examine the effect of gout on the risk of depression, represented using the hazard ratio with the 95% confidence interval.Patients with gout exhibited a higher risk of depressive disorders than controls did. The risk of depressive disorders increased with age and was higher in female patients and those with hypertension, stroke, and coronary artery disease. Nonsteroidal antiinflammatory drug and prednisolone use was associated with a reduced risk of depression. Patients with gout who had received antigout medication exhibited a reduced risk of depressive disorders compared with nongout patients.Our findings support that gout increases the risk of depressive disorders, and that antigout medication use reduces the risk.

    Acromegaly is a chronic disease characterized by hypersecretion of growth hormone (GH) and insulin-like growth factor 1 (IGF-1). Electrolyte disturbances such as hypercalcemia and hyperphosphatemia are reported in patients with this disorder. There is limited data on vitamin D status in subjects with acromegaly. The aim of the study was to determine calcium, inorganic phosphate, magnesium, alkaline phosphatase, and 25(OH)D levels with regard to the activity of the disease. We also studied correlations of 25(OH)D and IGF-1, GH, body mass, body mass index, and age. A study group consisted of 55 acromegalic patients, and was divided into three subgroups: active acromegaly (AA), well-controlled acromegaly (WCA), cured acromegaly (CA). We enrolled 29 healthy subjects to a control group (CG). Vitamin D deficiency was recorded in all AA patients, 13 WCA patients (92.86%), 10 CA patients (62.5%), and 13 controls (54.17%). The highest 25(OH)D levels were found in the CG group and the lowest in the AA group (p = 0.012). The dose of octreotide did not influence serum 25(OH)D levels. A significant positive correlation between IGF-1 and 25(OH)D levels was observed in the AA group (r = 0.58, p = 0.024). Inorganic phosphate levels were the highest in the AA group. In conclusion, active acromegalic patients have lower 25(OH)D levels in comparison with the CG and are at higher risk of vitamin D deficiency. PMID:26082755

    Background Active surveillance (AS) is increasingly offered to patients with low risk prostate cancer. The present study was conducted to evaluate the risk of tumor under-grading and -staging for AS eligibility. Moreover, we analyzed possible biomarkers for predicting more unfavorable final tumor histology. Methods 197 patients who underwent radical prostatectomy (RPE) but would have met the EAU (European Association of Urology) criteria for AS (PSA<10 ng/ml, biopsy GS ≤6, ≤2 cancer-positive biopsy cores with ≤50% of tumor in any core and clinical stage ≤T2a) were included in the study. These AS inclusion parameters were correlated to the final histology of the RPE specimens. The impact of preoperative PSA level (low PSA ≤4 ng/ml vs. intermediate PSA of >4–10 ng/ml), PSA density (<15 vs. ≥ 15 ng/ml) and the number of positive biopsy cores (1 vs. 2 positive cores) on predicting upgrading and final adverse histology of the RPE specimens was analyzed in uni- and multivariate analyses. Moreover, clinical courses of undergraded patients were assessed. Results In our patient cohort 41.1% were found under-graded in the biopsy (final histology 40.1% GS7, 1% GS8). Preoperative PSA levels, PSA density or the number of positive cores were not predictive for worse final pathological findings including GS >6, extraprostatic extension and positive resection margin (R1) or correlated significantly with up-grading and/or extraprostatic extension in a multivariate model. Only R1 resections were predictable by combining intermediate PSA levels with two positive biopsy cores (p = 0.004). Sub-analyses showed that the number of biopsy cores (10 vs. 15 biopsy cores) had no influence on above mentioned results on predicting biopsy undergrading. Clinical courses of patients showed that 19.9% of patients had a biochemical relapse after RPE, among all of them were undergraded in the initial biopsy. Conclusion In summary, this study shows that a multitude of patients fulfilling

    Objectives Historically, only 10% of patients with hepatocellular carcinoma (HCC) are diagnosed with early-stage, potentially curable disease. In this study, chronic hepatitis virus-infected patients were prospectively screened to determine: (i) the proportion of patients diagnosed with potentially curable HCC, and (ii) survival following curative therapy. Methods The study included 8900 chronic hepatitis virus-infected patients enrolled in a prospective screening programme, of whom 1335 (15.0%) were infected with hepatitis B virus (HBV), 7120 (80.0%) with hepatitis C virus (HCV), and 445 (5.0%) with both HBV and HCV. Screening was conducted every 6 months and included serum alpha-fetoprotein (AFP) measurement and ultrasonography. Curative treatments included liver transplantation, resection, radiofrequency ablation and/or ethanol injection. Results Hepatocellular carcinoma was diagnosed in 765 (8.6%) patients. Of 1602 patients with cirrhosis, 758 (47.3%) developed HCC. Curative treatment was possible in 523 (68.4%) of the 765 HCC patients. Two- and 5-year rates of overall survival in the curative treatment group were 65% and 28%, respectively, compared with 10% and 0% in the advanced disease group (P < 0.001). Conclusions Prospective screening of patients at high risk for the development of HCC increases the proportion of patients diagnosed with potentially curable disease. This may result in an increase in the number of longterm survivors. Screening strategies should focus on patients with chronic HBV or HCV infection who have progressed to cirrhosis because more than 40% of these patients will develop HCC. PMID:23607636

    Early palliative care (EPC) for patients with metastatic solid tumors is now standard of care, but the effect of EPC in hematopoietic cell transplantation (HCT) is less well understood. We studied the acceptability of pre-HCT EPC as measured by trial participation, changes in patient-reported outcomes, and follow-up with palliative care providers. English-speaking adults (age >17 years) with an HCT comorbidity index of ≥ 3, relapse risk > 25%, or planned HLA-mismatched allogeneic or myeloablative HCT received EPC before HCT admission with monthly or more frequent visits. Twenty-two (69%) of 32 subjects provided consent; 2 were later excluded (HCT cancelled, consent retracted) for a 63% participation rate. Comfort with EPC was high (82% very comfortable). Subjects reported stable or improved mood and sense of hope, without apparent negative effects with a median of 3 visits. Follow-up surveys were returned by 75% of participants at 60 days and by 65% at 90 days. Four (20%) were admitted to the intensive care unit before day 100 and 3 (15%) received life-support measures. Five (25%) died with median follow-up of 14 months. EPC is feasible, acceptable, and has the potential to improve the HCT experience, whether or not the patient survives. EPC for HCT patients should be tested in a randomized trial. PMID:26976242

    Introduction National guidance states that all patients having emergency surgery should have a mortality risk assessment calculated on admission so that the ‘high risk’ patient can receive the appropriate seniority and level of care. We aimed to assess if peri-operative risk scoring tools could accurately calculate mortality and morbidity risk. Methods Mortality risk scores for 86 consecutive emergency laparotomies, were calculated using pre-operative (ASA, Lee index) and post-operative (POSSUM, P-POSSUM and CR-POSSUM) risk calculation tools. Morbidity risk scores were calculated using the POSSUM predicted morbidity and compared against actual morbidity according to the Clavien–Dindo classification. Results The actual mortality was 10.5%. The average predicted risk scores for all laparotomies were: ASA 26.5%, Lee Index 2.5%, POSSUM 29.5%, P-POSSUM 18.5%, CR-POSSUM 10.5%. Complications occurred following 67 laparotomies (78%). The majority (51%) of complications were classified as Clavien–Dindo grade 2–3 (non-life-threatening). Patients having a POSSUM morbidity risk of greater than 50% developed significantly more life-threatening complications (CD 4–5) compared with those who predicted less than or equal to 50% morbidity risk (P = 0.01). Discussion Pre-operative risk stratification remains a challenge because the Lee Index under-predicts and ASA over-predicts mortality risk. Post-operative risk scoring using the CR-POSSUM is more accurate and we suggest can be used to identify patients who require intensive care post-operatively. Conclusions In the absence of accurate risk scoring tools that can be used on admission to hospital it is not possible to reliably audit the achievement of national standards of care for the ‘high-risk’ patient.

  12. Managing hypertension in high-risk patients: lessons and promises from the STRATHE and ADVANCE trials.

    PubMed

    Waeber, Bernard

    Pharmacological treatment of hypertension represents a cost-effective way of preventing cardiovascular and renal complications. To benefit maximally from antihypertensive treatment, blood pressure should be brought to below 140/90 mmHg in every hypertensive patient, and even lower (< 130/80 mmHg) if diabetes or renal disease co-exists. Such targets cannot usually be reached using monotherapies. This is especially true in patients who present with a high cardiovascular risk. The co-administration of two agents acting by different mechanisms considerably increases the blood pressure control rate. Such combinations are not only efficacious, but are also well tolerated, and some fixed low-dose combinations even have a placebo-like tolerability. This is the case for the preparation containing the angiotensin-converting enzyme inhibitor perindopril (2 mg) and the diuretic indapamide (0.625 mg), a fixed low-dose combination that has been shown in controlled trials to be more effective than monotherapies in reducing albuminuria, regressing cardiac hypertrophy and improving the stiffness of large arteries. Using this combination to initiate antihypertensive therapy has been shown in a double-blind trial (Strategies of Treatment in Hypertension: Evaluation; STRATHE) to normalize blood pressure (< 140/90 mmHg) in significantly more patients (62%) than a sequential monotherapy approach based on atenolol, losartan and amlodipine (49%) and a stepped-care strategy based on valsartan and hydrochlorothiazide (47%), with no difference between the three arm groups in terms of tolerability. An ongoing randomized trial (Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation; ADVANCE) is a study with a 2 x 2 factorial design assessing the effects of the fixed-dose perindopril-indapamide combination and of the intensive gliclazide modified release-based glucose control regimen in type 2 diabetic patients, with or without hypertension.

    Comparisons between transcatheter aortic valve implantation without replacement (TAVI) and tissue aortic valve replacement (AVR) in clinical trials might not reflect the outcomes in standard clinical practice. This could have important implications for the relative cost-effectiveness of these alternatives for management of severe aortic stenosis in high-risk patients for whom surgery is an option. The mean and variance of risks, transition probabilities, utilities, and cost of TAVI, AVR, and medical management derived from observational studies were entered into a Markov model that examined the progression of patients between relevant health states. The outcomes and cost were derived from 10,000 simulations. Sensitivity analyses were based on variations in the likelihood of mortality, stroke, and other commonly observed outcomes. Both TAVI and AVR were cost-effective compared to medical management. In the reference case (age 80 years, the perioperative TAVI and AVR mortality was 6.9% vs 9.8%, and annual mortality was 21% vs 24%), the utility of TAVI was greater than that of AVR (1.78 vs 1.72 quality-adjusted life years) and the lifetime cost of TAVI exceeded that of AVR ($59,503 vs $56,339). The incremental cost-effectiveness ratio was $52,773/quality-adjusted life years. Threshold analyses showed that variation in the probabilities of perioperative and annual mortality after AVR and after TAVI and annual stroke after TAVI were important determinants of the favored strategy. Sensitivity analyses defined the thresholds at which TAVI or AVR was the preferred strategy with regard to health outcomes and cost. In conclusion, TAVI satisfies current metrics of cost-effectiveness relative to AVR and might provide net health benefits at acceptable cost for selected high-risk patients among whom AVR is the current procedure of choice.

    Background Better breast cancer prognostication may improve selection of patients for adjuvant therapy. We conducted a retrospective follow-up study in which we investigated sera of high-risk primary breast cancer patients, to search for proteins predictive of recurrence free survival. Methods Two sample sets of high-risk primary breast cancer patients participating in a randomised national trial investigating the effectiveness of high-dose chemotherapy were analysed. Sera in set I (n = 63) were analysed by surface enhanced laser desorption ionisation time-of-flight mass spectrometry (SELDI-TOF MS) for biomarker finding. Initial results were validated by analysis of sample set II (n = 371), using one-dimensional gel-electrophoresis. Results In sample set I, the expression of a peak at mass-to-charge ratio 9198 (relative intensity ≤ 20 or > 20), identified as haptoglobin (Hp) alpha-1 chain, was strongly associated with recurrence free survival (global Log-rank test; p = 0.0014). Haptoglobin is present in three distinct phenotypes (Hp 1-1, Hp 2-1, and Hp 2-2), of which only individuals with phenotype Hp 1-1 or Hp 2-1 express the haptoglobin alpha-1 chain. As the expression of the haptoglobin alpha-1 chain, determined by SELDI-TOF MS, corresponds to the phenotype, initial results were validated by haptoglobin phenotyping of the independent sample set II by native one-dimensional gel-electrophoresis. With the Hp 1-1 phenotype as the reference category, the univariate hazard ratio for recurrence was 0.87 (95% CI: 0.56 – 1.34, p = 0.5221) and 1.03 (95% CI: 0.65 – 1.64, p = 0.8966) for the Hp 2-1 and Hp 2-2 phenotypes, respectively, in sample set II. Conclusion In contrast to our initial results, the haptoglobin phenotype was not identified as a predictor of recurrence free survival in high-risk primary breast cancer in our validation set. Our initial observation in the discovery set was probably the result of a type I error (i.e. false positive). This study

    Hereditary breast cancer accounts for 5-10% of all cases of breast cancer and 10-15% of ovarian cancer and is characterised by dominant inheritance, early onset, the severity of the disease and bilaterality. About 30% of cases with hereditary breast and ovarian cancer have mutations in the BRCA1 and BRCA2 genes. Women with a mutation in the BRCA1 gene have a 80-90% lifetime risk of developing breast cancer, and 40-65% chance of developing ovarian cancer. Most studies carried out throughout the world indicate that the prevalence of BRCA1 and BRCA2 mutation is lower than originally suggested by early studies on large families with several affected members. Studies performed in Italy have reported different prevalence of BRCA1 and BRCA2 mutations, probably due to different selection criteria and to the variability of the techniques used. In this study, we performed a screening of BRCA1 and BRCA2 in families from northern Italy with familial recurrence of breast cancer or ovarian cancer in which the individual risk of patients of being carriers of BRCA1 and BRCA2 mutation was evaluated using BRCAPRO (CAGene) software. We enrolled 27 patients of 101 unrelated families selected when they fulfilled the inclusion criteria of the American Society of Clinical Oncology (ASCO). Specific risk evaluation, genetic test administration if needed, and discussion of the results were offered during multi-disciplinary genetic, surgical and psychological counselling. Seven probands (35%) found BRCA1/2 sequence variation carriers; no BRCA1 and BRCA2 mutations were detected in the remaining 13 probands. Two (15%) patients had BRCA1 mutations and 5 (25%) patients had BRCA2 mutations. In the latter case, BRCA2 delA 9158fs+29stop mutation in exon 22, never previously described and a new sequence variation (T703N) in exon 11 were identified. PMID:21042765

    Purpose: There are multiple reported risk factors and a wide range of reported blood transfusion rates for total shoulder arthroplasty (TSA). There are no evidence-based guidelines for blood transfusions in TSA patients. Materials and Methods: We utilized the Nationwide Inpatient Sample to analyze 51,191 patients undergoing TSA between 1998 and 2011. The purpose was to describe the incidence and identify the preoperative factors that are independently associated with blood transfusion after TSA. In addition, we studied the association of blood transfusions with certain variables such as length of stay (LOS), total charges, and payer status. Results: The blood transfusion rate in our study was 6.1%. There was no difference in the rate of blood transfusions over the study period (P < 0.001). In our logistic regression model, significant associations were found with increased age (odds ratio [OR] =1.03), white race (OR = 1.05), higher Charlson-Deyo score (OR = 1.12), presence of ischemic heart disease (OR = 1.24), blood loss anemia (OR = 1.65), female gender (OR = 1.94), presence of coagulation disorders (OR = 2.25), and presence of deficiency anemia (OR = 3.5). Patients receiving a blood transfusion had higher total charges, a longer hospital LOS, and were more likely to be Medicare payers (P < 0.001). Conclusions: Our study found five clinically significant risk factors for blood transfusions for TSA: female gender, ischemic heart disease, deficiency anemia, coagulation disorder, and blood loss anemia. Patients with these risk factors should be considered higher risk for requiring a blood transfusion after TSA and counseled appropriately. Level of Evidence: Level II, retrospective cohort study, prognostic study. PMID:27186059

    The founder of humanistic psychology A. Maslow divided the needs of a personality into several levels--from the lowest to the highest ones. Higher-leveled needs rise when the lower-leveled needs are satisfied. A great deal of factors affect the origination and satisfaction of needs, but they are always interrelated with social values. The extent to which personality needs are satisfied in patients with pulmonary tuberculosis has not been studied. A special questionnaire has been drawn up to study the extent to which personality needs are met. Its suitability has been determined, by using a group of patients with bronchial asthma. The extent to which personality needs are satisfied in patients with pulmonary tuberculosis was studied in 178 patients with infiltrative pulmonary tuberculosis and 253 patients with fibrocavernous pulmonary tuberculosis. The results have shown that the extent to which personality needs are satisfied in patients with tuberculosis is lower than that in apparently healthy individuals of the same social status. In females with infiltrative pulmonary tuberculosis, the needs for safety are satisfied to a lesser extent. In those with fibrocavernous pulmonary tuberculosis, the extent to which the physiological, safety, and self-realization needs is decreased. In males with infiltrative pulmonary tuberculosis, the physiological, noetic, and self-realization needs are satisfied to a lesser extent. In those with fibrocavernous pulmonary tuberculosis, the extent to which the physiological, safety, group decision-making, noetic and self-realization needs is decreased. PMID:15801639

    20% of children suffering from high hyperdiploid acute lymphoblastic leukemia develop recurrent disease. The molecular mechanisms are largely unknown. Here, we analyzed the genetic landscape of five patients at relapse, who developed recurrent disease without prior high-risk indication using whole-exome- and whole-genome-sequencing. Oncogenic mutations of RAS pathway genes (NRAS, KRAS, FLT3, n=4) and deactivating mutations of major epigenetic regulators (CREBBP, EP300, each n=2 and ARID4B, EZH2, MACROD2, MLL2, each n=1) were prominent in these cases and virtually absent in non-recurrent cases (n=6) or other pediatric acute lymphoblastic leukemia cases (n=18). In relapse nucleotide variations were detected in cell fate determining transcription factors (GLIS1, AKNA). Structural genomic alterations affected genes regulating B-cell development (IKZF1, PBX1, RUNX1). Eleven novel translocations involved the genes ART4, C12orf60, MACROD2, TBL1XR1, LRRN4, KIAA1467, and ELMO1/MIR1200. Typically, patients harbored only single structural variations, except for one patient who displayed massive rearrangements in the context of a germline tumor suppressor TP53 mutation and a Li-Fraumeni syndrome-like family history. Another patient harbored a germline mutation in the DNA repair factor ATM. In summary, the relapse patients of our cohort were characterized by somatic mutations affecting the RAS pathway, epigenetic and developmental programs and germline mutations in DNA repair pathways.

    The majority of ovarian cancer patients with advanced disease at diagnosis will relapse following primary treatment, with a dismal prognosis. Monitoring the levels of serum markers in patients under follow-up may be essential for the early detection of relapse, and for distinguishing high-risk patients from those with less aggressive disease. The aim of the present study was to investigate the possible predictive value of human epididymis protein 4 (HE4) and carbohydrate antigen 125 (CA125) in relation to recurrence of epithelial ovarian cancer by measuring the two markers during follow-up subsequent to surgery and adjuvant first-line carboplatin/paclitaxel chemotherapy. Serum HE4 and CA125 were analyzed in 88 epithelial ovarian cancer patients at the end of treatment and consecutively during follow-up. The patients were divided into a high-risk and a low-risk group based on having an increase in HE4 and CA125 levels above or below 50% during follow-up, relative to the baseline (end-of-treatment) level. Disease recurrence was detected in 55 patients during follow-up. Patients with an increase in HE4 of >50% at 3- and 6-month follow-up compared to the end-of-treatment sample had significantly poorer progression-free survival (PFS) [hazard ratio (HR), 2.82 (95% CI, 0.91–8.79; P=0.0052) and HR, 7.71 (95% CI, 3.03–19.58; P<0.0001), respectively]. The corresponding 3- and 6-month biomarker assessments for increased CA125 levels (>50%) showed HRs of 1.86 (95% CI, 0.90–3.80; P=0.0512) and 2.55 (95% CI, 1.39–4.68; P=0.0011), respectively. Multivariate analysis confirmed HE4 as a predictor of short PFS, with an HR of 8.23 (95% CI, 3.28–20.9; P<0.0001) at 6-month follow-up. The increase of CA125 was not a significant prognostic factor in multivariate analysis for PFS. In conclusion, HE4 appears to be a sensitive marker of recurrence and instrumental in risk assessment during the first 6 months of follow-up. PMID:27313725

    A high level of low-density lipoprotein cholesterol (LDL-C) has proved to have a positive correlation with mortality from cardiovascular disease, and it is the key modifiable risk factor for cardiovascular disease. Lowering levels of LDL-C with statins reduces both vascular morbidity and mortality; however, myalgias occur in 10% to 15% of patients, and many patients managed with statins achieve suboptimal levels of LDL-C. The injectable drug alirocumab-the first of a new class of drugs called proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors-is a monoclonal antibody to the PCSK9 gene, which regulates LDL receptor expression and circulating levels of LDL-C. In this review, we evaluated the efficacy and safety of alirocumab and its potential role in the management of patients with high-risk cardiovascular disease. Data were gathered from articles indexed in the PubMed database (2006-April 2015). All English-language, prospective, randomized, double-blinded trials evaluating the efficacy of alirocumab, as a monotherapy or in combination with statins, for treatment of hypercholesterolemia were identified. Five clinical trials were evaluated, and the results from these studies revealed that the use of alirocumab, both as monotherapy or in combination with statins, significantly reduced LDL-C levels. Patients treated with alirocumab, with or without statins, were more likely to achieve LDL-C goals of less than 100 or 70 mg/dl compared with placebo. Despite its ability to lower LDL-C level, one study did not show any antiinflammatory activity (i.e., reduced C-reactive protein level) among patients who received alirocumab; however, more clinical trials will be needed to further assess this effect. Alirocumab also appears to cause regression of plaque. The most commonly reported adverse effect was mild injection-site reaction. With increased odds of statin discontinuation among patients taking high-intensity statins, alirocumab will contribute to

  1. Coaching patients during pulmonary function testing: A practical guide.

    Pulmonary function tests are an important tool to assist in the diagnosis and management of patients with respiratory disease. Ensuring that the tests are of acceptable quality is vital. Acceptable pulmonary function test quality requires, among others, optimal patient performance. Optimal patient performance, in turn, requires adequate coaching from registered respiratory therapists (RRTs) and other pulmonary function laboratory personnel. The present article provides techniques and tips to help RRTs coach patients during testing. The authors briefly review the components of pulmonary function testing, then describe factors that may hinder a patient's performance, list common mistakes that patients make during testing, and provide tips that RRTs can use to help patients optimize their performance.

    To explore the nucleotide sequence variability of the E2 gene in high-risk HPV types in cervical cancer patients from Sichuan province, China, the E2 genes of eight high-risk HPV types were amplified and sequenced. Several novel nucleotide substitutions and deletions were observed. The lineages to which the isolates belonged were determined by phylogenetic analysis, employing the sequence of the representative lineages/sublineages in the coherent classification and nomenclature system as references. This study updates the lineage distribution data on high-risk HPV types in Southwest China and helps broaden understanding of the polymorphism of the E2 gene. PMID:26303138

    Cardiovascular disease remains the leading cause of morbidity and mortality in developed countries. Obstructive sleep apnea is a highly prevalent condition characterized by repetitive upper airway collapse during sleep. A large body of evidence suggests that obstructive sleep apnea is associated with the development of cardiovascular disease and increased cardiovascular morbidity and mortality. Continuous positive airway pressure (CPAP) is the current gold standard for the treatment of obstructive sleep apnea. CPAP devices maintain upper airway patency using a pneumatic splint, thereby ameliorating the repetitive deoxygenation and reoxygenation characteristic of sleep in obstructive sleep apnea patients. Accumulating evidence suggests that CPAP treatment may lead to a reduction in blood pressure. Limited evidence also suggests that CPAP therapy may modulate glucose metabolism, serum cholesterol levels, and inflammatory biomarkers. Thus, CPAP treatment may be associated with cardiovascular risk factor modification in patients with obstructive sleep apnea, who are often obese and at an increased risk of developing cardiovascular disease. This review updates the knowledge on the effects of CPAP on cardiovascular risk factors from recently published randomized trials. PMID:26370408

    In an attempt to illustrate the relevance of psychoanalytic theory and research to behavior medicine, an empirical investigation was conducted of females treated at a high-risk pregnancy specialty clinic (N = 58). Drawing from psychoanalytic object relations theory, it was hypothesized and confirmed that use of projection as a defense mechanism during pregnancy, superimposed on simplistic object relations, predicted an erosion of patient-provider relationships during the pregnancy/postdelivery period. Findings are interpreted through the perspective of mentalization, pertaining to individuals' ability to understand the mental states of self and others, specifically under significant stress. Implications for psychoanalytically oriented assessment and treatment, and for the rift between psychoanalysis and research, are discussed. PMID:21156840

    Prevalence of pulmonary arterial hypertension (PAH) was studied by echocardiography and Doppler in 43 splenectomized patients with various disorders 1-20 years after splenectomy. Pulmonary arterial hypertension was detected only in thalassemia major, intermedia, hereditary sphereocytosis and myelofibrosis groups comprising a total of 21 patients. Six patients out of 21 was found to have PAH with mean pulmonary arterial pressure of 46.28 ± 28.17 mm of Hg. Twenty-one controls having similar duration and type of disease also were assessed for PAH in this case control study 3/21 had pulmonary arterial hypertension in this control group. The difference in number of patients showing pulmonary hypertension between case and control was not statistically significant (Chi square test P=0.29) though the difference in pulmonary arterial pressure between case and control were significantly different (t test P<0.0029) with control group showing a mean pulmonary arterial pressure of 25 ± 19 mm Hg.Platelet count in the splenectomized group was significantly higher (P=0.0029) than the controls. Pulmonary thromboembolism was equally high in the PAH patients with and without splenectomy. Patients undergoing splenectomy due to trauma, immune thrombocytopenia, sideroblastic anemia, extrahepatic portal hypertension, autoimmune hemolytic anemia did not show PAH after splenectomy even years after the procedure PAH following splenectomy is common after certain disorders and control patients in these diseases have tendency to develop PAH even without splenectomy. Pulmonary thromboembolism may be an important pathophysiological mechanism leading to this condition. Patients having hemolytic anemia and myelofibrosis should have regular evaluation of pulmonary arterial pressure whether he/she has been splenectomized or not.This is particularly important as availability of phosphodiesterase inhibitors such as sildenafil allows one to manage these cases.

    Background The prevalence of pulmonary hypertension is unusually high in Taiwanese patients with end-stage renal disease. Thrombosis of hemodialysis grafts is common and pulmonary embolism has been reported after endovascular thrombectomy. The aim of this study was to evaluate the relationship between pulmonary hypertension and endovascular thrombectomy of hemodialysis grafts. Methods One hundred and ten patients on hemodialysis via arteriovenous grafts were enrolled in our study. The mean pulmonary artery pressure (PAP) was measured by right heart catheterization. Clinical information was collected by review of medical records. Comorbid cardiopulmonary disease was evaluated by echocardiography and chest X-ray. The history of patient vascular access thrombosis was reviewed from database, hemodialysis records, and interviews with staff at hemodialysis centers. Results Fifty-two participants (47%) had pulmonary hypertension diagnosed by right heart catheterization. There was no difference in the number of thrombectomy procedures between patients with and without pulmonary hypertension. Based on multivariate analysis, the number of prior endovascular thrombectomy procedures did not correlate with mean PAP (F-value = 1.10, p = 0.30) nor was it associated with pulmonary hypertension (odds ratio = 0.92, p = 0.17). Conclusions Prior endovascular arteriovenous graft thrombectomies were not associated with pulmonary hypertension or increased mean PAP in end-stage renal disease patients on maintenance hemodialysis.

    The Massachusetts General Care Management Program (Mass General CMP or CMP) was designed as a federally supported demonstration to test the impact of intensive, practice-based care management on high-cost Medicare fee-for-service (FFS) beneficiaries—primarily older persons—with multiple hospitalisations and multiple chronic conditions. The Massachusetts General Care Management Program operated over a 6-year period in two phases (3 years each). It started during the first phase at Massachusetts General Hospital, a major academic medical centre in Boston, Massachusetts in collaboration with Massachusetts General Physicians Organisation. During the second phase, the programme expanded to two more affiliated sites in and around the Boston area, including a community hospital, as well as incorporated several modifications primarily focused on the management of transitions to post-acute care in skilled nursing facilities. At the close of the demonstration in July 2012, Mass General Massachusetts General Care Management Program became a component of a new Pioneer accountable care organisation (ACO). The Massachusetts General Care Management Program is focused on individuals meeting defined eligibility criteria who are offered care that is integrated by a case manager embedded in a primary care practice. The demonstration project showed substantial cost savings compared to fee-for-service patients served in the traditional Medicare system but no impact on hospital readmissions. The Massachusetts General Care Management Program does not rest upon a “whole systems” approach to integrated care. It is an excellent example of how an innovative care co-ordination programme can be implemented in an existing health-care organisation without making fundamental changes in its underlying structure or the way in which direct patient care services are paid for.

    Background: The guidewire biliary cannulation (GWC) technique may increase the cannulation rate and decrease the risk for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. The aim of our multicenter prospective randomized controlled trial was to determine if the use of an atraumatic loop-tip guidewire reduces the rate of post-ERCP pancreatitis (PEP) compared with the standard contrast-assisted cannulation (CC) technique. Methods: From June 2012 to December 2013, a total of 320 patients who had a naïve papilla and were referred for ERCP were randomly assigned to the GWC group (n = 160) or the CC group (n = 160). GWC or CC was randomly used. In cases of failed cannulation in both arms after crossover, biliary access was attempted with alternative techniques (e. g., dual-wire technique, pancreatic duct stenting, precut). Results: The biliary cannulation rates were 81 % in the GWC group and 73 % in the CC group (P = n. s.). Following crossover, cannulation was successful in 8 % and 11 % of patients in the GWC and CC groups, respectively. With use of an alternative technique, the cannulation rates were 98 % in the GWC group and 96 % in the CC group, respectively. The rates of PEP were 5 % in the GWC group and 12 % in the CC group (P = 0.027). The post-interventional complication rates did not differ between the two groups. Conclusion: GWC with the new wire guide is associated with a lower rate of PEP in comparison with the CC technique. Clinical trial reference number: NCT01771419 PMID:26528503

    Many healthcare systems are struggling with the issue of providing high-quality care to high-needs patients at lower costs. Our comments in this paper draw on insights that we have gained from the development and implementation of integrated models of care in Québec. This experience highlights the importance of developing a clear clinical approach to the delivery and coordination of care and to support providers in new roles. Our second insight is that system-level policy guidelines may help to focus the attention of organizations and providers on key priorities, but they need to take into account differing needs in various contexts. Third, a crucial factor for success over the longer term is the ability of local networks to reshape the allocation and use of resources to bring about change in day-to-day operations. We conclude by highlighting key characteristics of high-performing health systems and with the final observation that politicians and policymakers need to allow enough time to harness the full benefit of change initiatives.

  11. Pulmonary endarterectomy: the potentially curative treatment for patients with chronic thromboembolic pulmonary hypertension.

    PubMed

    Jenkins, David

    2015-06-01

    Pulmonary endarterectomy (PEA) is the treatment of choice to relieve pulmonary artery obstruction in patients with chronic thromboembolic pulmonary hypertension (CTEPH). It is a complex surgical procedure with a simple principle: removal of obstructive thromboembolic material from the pulmonary arteries in order to reduce pulmonary vascular resistance, relieve pulmonary hypertension (PH) and alleviate right ventricular dysfunction. In the majority of patients there is symptomatic and prognostic benefit. However, not all patients with CTEPH are suitable for treatment with PEA. Operability assessment is not always easy, being largely subjective and based on experience. It is therefore important that all patients are referred to an experienced CTEPH centre for careful evaluation of suitability for surgery. The most common reason for inoperability is distal vasculopathy accounting for a high proportion of the vascular resistance. Surgery requires cardiopulmonary bypass and periods of deep hypothermic circulatory arrest. Complications include reperfusion lung injury and persistent PH. However, with careful patient selection, surgical technique and post-operative management, PEA is a highly effective treatment with mortality rates <5% at experienced centres. Patients who are unsuitable for surgery may be candidates for medical therapy. PMID:26028638

    An interactive audio and video telemedicine feasibility program was established to provide counseling on breast cancer risk-reducing strategies for underserved, high-risk Alaskan native women through a collaboration among the Alaska Native Medical Center, the Mayo Clinic Breast Clinic, Mayo's Center for Innovation, and the Alaska Federal Health Care Access Network. The telemedicine model included a navigator to facilitate patient encounters (referrals, electronic records, and scheduling) and a subscription billing contract. Between January 1 and December 31, 2011, 60 consultations were provided to the Alaska Native Medical Center. A survey of a sample of 15 women demonstrated overall patient satisfaction of 98% pertaining to the experience, technology, and medical consultation. The referring physician satisfaction, from 11 visit surveys and 8 referring physicians, revealed 99% satisfaction with the service. In this telemedicine pilot study, we demonstrated the feasibility of a telemedicine program to provide integrated specialty care that resulted in a positive effect on patient satisfaction. This program has a sustainable business model, thus creating a new modality for health care delivery. PMID:23274020

    Testing of patients who are deemed to be at high risk for TORCH pathogens, e.g., pregnant women, their fetuses, neonates, and acquired immunodeficiency syndrome (AIDS) patients, is important so that specific treatment can be initiated. This study included 1,857 such patients between 2005 and 2008. Logistic regression was used to evaluate factors associated with Toxoplasma gondii seropositivity. Among 823 women of childbearing age, 35.1% and 5.2% tested positive for T. gondii IgG and IgM, respectively. Three infants ≤ 6 months of age (0.8% of 353) were congenitally infected. Factors associated with T. gondii IgG seropositivity included older age, East Mediterranean or African nationality, positive cytomegalovirus (CMV) and herpes simplex virus (HSV)-1 serostatus, and negative rubella IgG results. The decreasing prevalence of IgM antibodies between 2005 and 2008 suggested that exposure to T. gondii from food or environmental sources declined over this period in Qatar. Population-based studies of newborns would be helpful to accurately estimate incidence of congenital toxoplasmosis. PMID:20348511

    A 90-year-old female patient was admitted to our clinic complaining of pain in her left hip which occurred due to fall from a chair. Her medical history included memory loss and mental changes associated with Alzheimer's disease and depression. Patient's cooperation and orientation were weak. Range of motion of the left hip was restricted and painful. Radiographs of the left hip demonstrated subtrochanteric comminuted fracture of femur. Laboratory tests revealed anemia and liver insufficiency. Departments of internal medicine and anesthesiology reported high risk for surgery. Surgery was performed under spinal anesthesia on radiolucent table and in supine position. Using fluoroscopy, subtrochanteric comminuted fracture of femur was reduced. Proximally, two Schanz screws were placed through femoral neck and head in axial plane, and distally, three Schanz screws were placed through femoral shaft in coronal plane. Finally, fixation of the screws was achieved with an external fixator which was made of carbon fiber rods. Patient was allowed to sit in the bed and move around with a wheelchair as of the day of surgery. No infection or loosening of fixator occurred. PMID:27499322

    As policy makers seek to slow the growth in Medicare spending, they have appropriately focused attention on beneficiaries with multiple chronic conditions. Many care coordination and disease management programs designed to improve beneficiaries' care and reduce their need for hospitalizations have been tested, but few have been successful. This study, however, found that four of eleven programs that were part of the Medicare Coordinated Care Demonstration reduced hospitalizations by 8-33 percent among enrollees who had a high risk of near-term hospitalization. The six approaches practiced by care coordinators in at least three of the four programs were as follows: supplementing telephone calls to patients with frequent in-person meetings; occasionally meeting in person with providers; acting as a communications hub for providers; delivering evidence-based education to patients; providing strong medication management; and providing timely and comprehensive transitional care after hospitalizations. When care management fees were included, the programs were essentially cost-neutral, but none of these programs generated net savings to Medicare. Our results suggest that incorporating these approaches into medical homes, accountable care organizations, and other policy initiatives could reduce hospitalizations and improve patients' lives. However, the approaches would save money only if care coordination fees were modest and organizations found cost-effective ways to deliver the interventions. PMID:22665827

    OBJECTIVE Prescription custom-made footwear can only be effective in preventing diabetic foot ulcers if worn by the patient. Particularly, the high prevalence of recurrent foot ulcers focuses the attention on adherence, for which objective data are nonexisting. We objectively assessed adherence in patients with high risk of ulcer recurrence and evaluated what determines adherence. RESEARCH DESIGN AND METHODS In 107 patients with diabetes, neuropathy, a recently healed plantar foot ulcer, and custom-made footwear, footwear use was measured during 7 consecutive days using a shoe-worn, temperature-based monitor. Daily step count was measured simultaneously using an ankle-worn activity monitor. Patients logged time away from home. Adherence was calculated as the percentage of steps that prescription footwear was worn. Determinants of adherence were evaluated in multivariate linear regression analysis. RESULTS Mean ± SD adherence was 71 ± 25%. Adherence at home was 61 ± 32%, over 3,959 ± 2,594 steps, and away from home 87 ± 26%, over 2,604 ± 2,507 steps. In 35 patients with low adherence (<60%), adherence at home was 28 ± 24%. Lower BMI, more severe foot deformity, and more appealing footwear were significantly associated with higher adherence. CONCLUSIONS The results show that adherence to wearing custom-made footwear is insufficient, particularly at home where patients exhibit their largest walking activity. This low adherence is a major threat for reulceration. These objective findings provide directions for improvement in adherence, which could include prescribing specific off-loading footwear for indoors, and they set a reference for future comparative research on footwear adherence in diabetes.

    Sentinel lymph node status is a major prognostic marker in locally invasive cutaneous melanoma. However, this procedure is not always feasible, requires advanced logistics and carries rare but significant morbidity. Previous studies have linked markers of tumour biology to patient survival. In this study, we aimed to combine the predictive value of established biomarkers in addition to clinical parameters as indicators of survival in addition to or instead of sentinel node biopsy in a cohort of high-risk melanoma patients. Patients with locally invasive melanomas undergoing sentinel lymph node biopsy were ascertained and prospectively followed. Information on mortality was validated through the National Death Index. Immunohistochemistry was used to analyse proteins previously reported to be associated with melanoma survival, namely Ki67, p16 and CD163. Evaluation and multivariate analyses according to REMARK criteria were used to generate models to predict disease-free and melanoma-specific survival. A total of 189 patients with available archival material of their primary tumour were analysed. Our study sample was representative of the entire cohort (N = 559). Average Breslow thickness was 2.5 mm. Thirty-two (17%) patients in the study sample died from melanoma during the follow-up period. A prognostic score was developed and was strongly predictive of survival, independent of sentinel node status. The score allowed classification of risk of melanoma death in sentinel node-negative patients. Combining clinicopathological factors and established biomarkers allows prediction of outcome in locally invasive melanoma and might be implemented in addition to or in cases when sentinel node biopsy cannot be performed.

    Transcatheter valve implantation continues to grow worldwide and has been used principally for the nonsurgical management of native aortic valvular disease-as a potentially less invasive method of valve replacement in high-risk and inoperable patients with severe aortic valve stenosis. Given the burden of valvular heart disease in the general population and the increasing numbers of patients who have had previous valve operations, we are now seeing a growing number of high-risk patients presenting with prosthetic valve stenosis, who are not potential surgical candidates. For this high-risk subset transcatheter valve delivery may be the only option. Here, we present an inoperable patient with severe, prosthetic valve aortic and mitral stenosis who was successfully treated with a trans catheter based approach, with a valve-in-valve implantation procedure of both aortic and mitral valves.

    BACKGROUND--Bronchiectasis and pulmonary infections are common in patients with hypogammaglobulinaemia. Despite intravenous gammaglobulin treatment and appropriate antibiotics, a subgroup of patients remains with persistent localised pulmonary infection in segments where bronchiectasis had developed before appropriate treatment. As such localised pulmonary suppuration (segmental or lobar) may serve as a focus for progression of bronchiectasis, surgical resection of the involved segments may be considered. The outcome of pulmonary resection in four such patients is reported. RESULTS--Surgery was well tolerated except for one postoperative empyema. Information on follow up is available from 3.5 to 5 years. All patients experienced considerable reduction of symptoms including cough, sputum production, antibiotic use, and hospital admissions. CONCLUSIONS--Surgical resection of localised bronchiectatic segments should be considered in patients with hypogammaglobulinaemia with persistent localised suppuration and symptoms refractory to medical treatment.

    Introduction: Prognosis of prostate cancer depends on the risk stratification. D’Amico classification, the most commonly used risk stratification method is based on three factors, i.e., prostate specific antigen (PSA), Gleason grade and clinical stage. The impact of presence of multiple risk factors on prognosis after radical prostatectomy has not been studied in Indian patients. We analyzed the outcome of patients with high-risk disease undergoing robotic-assisted radical prostatectomy (RARP), as per D’Amico classification. Materials and Methods: Our study is a review of the data of all patients with high-risk prostate cancer who underwent RARP between July 2010 and January 2015. Preoperative, perioperative and outcome data were analyzed for patients with high-risk disease as per D’Amico classification. Results: Of 227 patients who underwent RARP, 90 (39.6%) were in the high-risk group. PSA > 20 ng/ml was the most common risk factor, present in 50 (55.6%) patients. All three risk factors were present in 3 patients, and single risk factor was present in 65 patients. Nine (10%) patients had lymphnode involvement, 18 (20%) had positive margin, and 38 (41.1%) had extraprostatic extension (EPE). Among these adverse outcomes, only EPE showed significant association with multiplicity of risk factors. At 12 months, 27.8% had biochemical recurrence (BCR). 92% of patients were continent at 12 months. Conclusion: About 92% of patients with high-risk disease were continent at 12 months, whereas less than one-third of the patients had BCR. EPE was the only outcome associated with multiplicity of risk factors. Adjuvant treatment is not required in two-thirds of patients. PMID:27127353

    Background/Aims Recent data suggest that the incidence of ulcerative colitis (UC) related colorectal cancer (CRC) in India is similar to that of West. The optimum method for surveillance is still a debate. Surveillance with random biopsies has been the standard of care, but is a tedious process. We therefore undertook this study to assess the yield of random biopsy in dysplasia surveillance. Methods Between March 2014 and July 2015, patients of UC attending the Inflammatory Bowel Disease clinic at the All India Institute of Medical Sciences with high risk factors for CRC like duration of disease >15 years and pancolitis, family history of CRC, primary sclerosing cholangitis underwent surveillance colonoscopy for dysplasia. Four quadrant random biopsies at 10 cm intervals were taken (33 biopsies). Two pathologists examined specimens for dysplasia, and the yield of dysplasia was calculated. Results Twenty-eight patients were included. Twenty-six of these had pancolitis with a duration of disease greater than 15 years, and two patients had associated primary sclerosing cholangis. No patient had a family history of CRC. The mean age at onset of disease was 28.89±8.73 years and the duration of disease was 19.00±8.78 years. Eighteen patients (64.28%) were males. A total of 924 biopsies were taken. None of the biopsies revealed any evidence of dysplasia, and 7/924 (0.7%) were indefinite for dysplasia. Conclusions Random biopsy for surveillance in longstanding extensive colitis has a low yield for dysplasia and does not suffice for screening. Newer techniques such as chromoendoscopy-guided biopsies need greater adoption. PMID:27433149

    Objective This prospective study aimed to identify antibody profiles characterising mothers with fetuses developing congenital heart block (CHB) by comparing their antibody frequencies and levels with those in unaffected mothers. Methods Eighty-one consecutive pregnant patients positive to anti-Ro±anti-La antibodies, at high risk of developing fetal CHB were prospectively studied. The 16 patients with fetal CHB outcome were considered the study population and the 65 patients with normal pregnancy outcomes were considered the control cohort. Anti-Ro52, anti-Ro60, anti-p200 and anti-La antibodies were assayed using home-made ELISA assays. Results The prevalence of anti-p200 antibodies was significantly higher in the fetal CHB affected patients than in the controls (p=0.03). Combinations of anti-p200 with anti-Ro52 and anti-Ro60 antibodies were significantly more frequent in the women with fetuses developing CHB than in the controls (p=0.03 for all combinations). The women with fetal CHB had significantly higher mean anti-Ro52, anti-Ro60 and anti-p200 levels than the controls (p=0.003, p=0.0001 and p=0.04, respectively); mean anti-La/SSB level was not significantly different in the two cohorts (p=0.25). Conclusions Since anti-p200, anti-Ro52 and anti-Ro60 antibodies, especially at high level, seem to identify patients at increased risk of developing fetal CHB, their detection could recognise anti-Ro/La positive women at risk for having an infant with this rare, potentially dangerous disorder.

    Atelectasis and bronchopneumonia occur frequently in patients undergoing aorto-iliac reconstructive surgery. Transverse (T) incisions in upper abdominal surgery are thought to be followed by fewer pulmonary complications than midline incisions (M) but reports remain controversial. We studied the incidence of postoperative pulmonary complications and lung dysfunction after T and M incisions for aorto-iliac surgery in 13 patients with chronic obstructive pulmonary disease (COPD) and 13 control patients with normal lungs (C). For all subjects, we evaluated (1) postoperative clinical or radiological pulmonary events; (2) preoperatively and on postoperative days 2 (D2), 5 (D5), 9 (D9) and 12 (D12) - the forced expiratory volume in 1 s (FEV1), vital capacity (VC), alveolar-arterial oxygen difference (AaPO2), and (3) convenience for the surgeon. Operatively, aortic exposure was excellent with both incisions. Bronchopneumonia occurred only after M in five patients (1 C, 4 COPD). In contrast with the control patients in whom no difference was found between T and M incisions, the FEV1 of COPD patients was significantly less impaired with T than with M incisions (p less than 0.005 on D2 and p less than 0.05 on D5). VC decreased similarly with both incisions on D2 but on D5 the improvement was less with M (p less than 0.005). Changes in AaPO2 were more marked on D2 and D5 for the COPD patients with M incisions. We conclude that (1) in patients with chronic obstructive pulmonary disease, laparotomy with a transverse incision was associated with better postoperative lung function and fewer pulmonary complications; (2) in patients without pulmonary disease, midline and transverse incisions were equivalent.

    AIM: To determine the added value of hepatobiliary phase (HBP) gadoxetic acid-enhanced magnetic resonance imaging (MRI) in evaluating hepatic nodules in high-risk patients. METHODS: The institutional review board approved this retrospective study and waived the requirement for informed consent. This study included 100 patients at high risk for hepatocellular carcinoma (HCC) and 105 hepatic nodules that were larger than 1 cm. A blind review of two MR image sets was performed in a random order: set 1, unenhanced (T1- and T2-weighted) and dynamic images; and set 2, unenhanced, dynamic 20-min and HBP images. The diagnostic accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were compared for the two image sets. Univariate and multivariate analyses were performed on the MR characteristics utilized to diagnose HCC. RESULTS: A total of 105 hepatic nodules were identified in 100 patients. Fifty-nine nodules were confirmed to be HCC. The diameter of the 59 HCCs ranged from 1 to 12 cm (mean: 1.9 cm). The remaining 46 nodules were benign (28 were of hepatocyte origin, nine were hepatic cysts, seven were hemangiomas, one was chronic inflammation, and one was focal fat infiltration). The diagnostic accuracy significantly increased with the addition of HBP images, from 88.7% in set 1 to 95.5% in set 2 (P = 0.002). In set 1 vs set 2, the sensitivity and NPV increased from 79.7% to 93.2% and from 78.9% to 91.8%, respectively, whereas the specificity and PPV were not significantly different. The hypointensity on the HBP images was the most sensitive (93.2%), and typical arterial enhancement followed by washout was the most specific (97.8%). The multivariate analysis revealed that typical arterial enhancement followed by washout, hyperintensity on T2-weighted images, and hypointensity on HBP images were statistically significant MRI findings that could diagnose HCC (P < 0.05). CONCLUSION: The addition of HBP gadoxetic acid

    Human saliva plays a pivotal role in digesting food and maintaining oral hygiene. The presence of electrolytes, mucus, glycoproteins, enzymes, antibacterial compounds, and gingival crevicular fluid in saliva ensures the optimum condition of oral cavity and general health condition. Saliva collection has been proven non-invasive, convenient, and inexpensive compared to conventional venipuncture procedure. These distinctive advantages provide a promising potential of saliva as a diagnostic fluid. Through comprehensive analysis, an array of salivary proteins and peptides may be beneficial as biomarkers in oral and systemic diseases. In this review, we discuss the utility of human salivary proteomes and tabulate the recent salivary biomarkers found in subjects with acute myocardial infarction as well as respective methods employed. In a clinical setting, since acute myocardial infarction contributes to large cases of mortality worldwide, an early intervention using these biomarkers will provide an effective solution to reduce global heart attack incidence particularly among its high-risk group of type-2 diabetes mellitus patients. The utility of salivary biomarkers will make the prediction of this cardiac event possible due to its reliability hence improve the quality of life of the patients. Current challenges in saliva collection are also addressed to improve the quality of saliva samples and produce robust biomarkers for future use in clinical applications. PMID:25897294

    The immunosurveillance mechanisms governing high-risk neuroblastoma (HR-NB), a major pediatric malignancy, have been elusive. We identify a potential role for natural killer (NK) cells, in particular the interaction between the NK receptor NKp30 and its ligand, B7-H6, in the metastatic progression and survival of HR-NB after myeloablative multimodal chemotherapy and stem cell transplantation. NB cells expressing the NKp30 ligand B7-H6 stimulated NK cells in an NKp30-dependent manner. Serum concentration of soluble B7-H6 correlated with the down-regulation of NKp30, bone marrow metastases, and chemoresistance, and soluble B7-H6 contained in the serum of HR-NB patients inhibited NK cell functions in vitro. The expression of distinct NKp30 isoforms affecting the polarization of NK cell functions correlated with 10-year event-free survival in three independent cohorts of HR-NB in remission from metastases after induction chemotherapy (n = 196, P < 0.001), adding prognostic value to known risk factors such as N-Myc amplification and age >18 months. We conclude that the interaction between NKp30 and B7-H6 may contribute to the fate of NB patients and that both the expression of NKp30 isoforms on circulating NK cells and the concentration of soluble B7-H6 in the serum may be clinically useful as biomarkers for risk stratification.

    Background: Dental caries is the most common complaint encountered in clinical practice. Virtually every adult in the world has experience of dental caries. It affects almost 80% of the population. It is now being viewed in dual perspective- “caries as a disease” and “caries as a lesion”. Aims: To evaluate the efficacy of Triphaladi Gandusha for its anti-caries activity and improvement in Oral Hygiene Index in high risk patients of dental caries and to compare the efficacy of prevalent method of mouth rinsing and classical method of Gandusha. Materials and Methods: The study was conducted in 40 patients, 20 in each Group-1 and 2. Group -1 was given prepared Triphaladi mouthwash (mouth rinse) while Group-2 was given Triphaladi Kwath for Gandusha (retention). Results: The effect of treatment was assessed by subjective and objective parameters (like salivary pH, buffering capacity and microbial count). Triphaladi Gandusha (retention) in Group - 2 provided better results in the improvement of Ruja (toothache), Dantaharsha (tooth sensitivity), Sarambha (inflammation), pH of saliva, microbial count in salivary sample. And Triphaladi Mouthwash in Group - 1 provided better results in Srava (discharge), bad breath, pH of saliva and buffering capacity of salivary sample. There was no improvement in Chidrata (cavity formation), Krishnata (discoloration) and Chaladanta (mobility) with Triphaladi Gandusha and mouthwash. Conclusion: Study concluded that although both groups were effective, but Gandusha group patients’ got better relief in subjective symptoms compared to mouthwash group. PMID:25364198

    Introduction Severe chronic obstructive pulmonary disease (COPD) is often associated with secondary pulmonary hypertension (PH), which worsens prognosis. PH can be lowered by oxygen, but also by inhaled nitric oxide (NO), which has the potential to improve the health status of these patients. NO is an important mediator in vascular reactions in the pulmonary circulation. Oral compounds can act through NO-mediated pathways, but delivering pulsed inhaled NO (iNO) directly to the airways and pulmonary vasculature could equally benefit patients. Therefore, a proof-of-concept study was performed to quantify pulmonary blood vessel caliber changes after iNO administration using computed tomography (CT)-based functional respiratory imaging (FRI). Methods Six patients with secondary PH due to COPD received “pulsed” iNO in combination with oxygen for 20 minutes via a nasal cannula. Patients underwent a high-resolution CT scan with contrast before and after iNO. Using FRI, changes in volumes of blood vessels and associated lobes were quantified. Oxygen saturation and blood pressure were monitored and patients were asked about their subjective feelings. Results Pulmonary blood vessel volume increased by 7.06%±5.37% after iNO. A strong correlation (Ω20=0.32, P=0.002) was obtained between ventilation and observed vasodilation, suggesting that using the pulsed system, iNO is directed toward the ventilated zones, which consequently experience more vasodilation. Patients did not develop oxygen desaturation, remained normotensive, and perceived an improvement in their dyspnea sensation. Conclusion Inhalation of pulsed NO with oxygen causes vasodilation in the pulmonary circulation of COPD patients, mainly in the well-ventilated areas. A high degree of heterogeneity was found in the level of vasodilation. Patients tend to feel better after the treatment. Chronic use trials are warranted. PMID:27462149

    Importance Age-related macular degeneration (AMD) remains the leading cause of blindness in developed countries, and affects more than 150 million worldwide. Despite effective anti-angiogenic therapies for the less prevalent neovascular form of AMD, treatments are lacking for the more prevalent dry form. Similarities in risk factors and pathogenesis between AMD and atherosclerosis have led investigators to study the effects of statins on AMD incidence and progression with mixed results. A limitation of these studies has been the heterogeneity of AMD disease and the lack of standardization in statin dosage. Objective We were interested in studying the effects of high-dose statins, similar to those showing regression of atherosclerotic plaques, in AMD. Design Pilot multicenter open-label prospective clinical study of 26 patients with diagnosis of AMD and the presence of many large, soft drusenoid deposits. Patients received 80 mg of atorvastatin daily and were monitored at baseline and every 3 months with complete ophthalmologic exam, best corrected visual acuity (VA), fundus photographs, optical coherence tomography (OCT), and blood work (AST, ALT, CPK, total cholesterol, TSH, creatinine, as well as a pregnancy test for premenopausal women). Results Twenty-three subjects completed a minimum follow-up of 12 months. High-dose atorvastatin resulted in regression of drusen deposits associated with vision gain (+ 3.3 letters, p = 0.06) in 10 patients. No subjects progressed to advanced neovascular AMD. Conclusions High-dose statins may result in resolution of drusenoid pigment epithelial detachments (PEDs) and improvement in VA, without atrophy or neovascularization in a high-risk subgroup of AMD patients. Confirmation from larger studies is warranted. PMID:27077128

    Objectives To evaluate if diastolic pulmonary gradient (DPG) can predict survival in patients with pulmonary hypertension due to left heart disease (PH-LHD). Background Patients with combined post- and pre-capillary PH-LHD have worse prognosis than those with passive pulmonary hypertension. The transpulmonary gradient (TPG) and pulmonary vascular resistance (PVR) have commonly been used to identify high-risk patients. However, these parameters have significant shortcomings and do not always correlate with pulmonary vasculature remodeling. Recently, it has been suggested that DPG may be better marker, yet its prognostic ability in patients with cardiomyopathy has not been fully assessed. Methods A retrospective cohort of 1236 patients evaluated for unexplained cardiomyopathy at Johns Hopkins Hospital was studied. All patients underwent right heart catheterization and were followed until death, cardiac transplantation or the end of the study period (mean time 4.4 years). The relationships between DPG, TPG or PVR and survival in subjects with PH-LHD (n=469) were evaluated with Cox Proportional Hazards Regression and Kaplan Meier analyses. Results DPG was not significantly associated with mortality (HR 1.02; p=0.10) in PH-LHD whereas elevated TPG and PVR predicted death (HR 1.02, p=0.046 and HR 1.11, p=0.002, respectively). Similarly, DPG did not differentiate survivors from non-survivors at any selected cutpoints including a DPG of 7mmHg. Conclusions In this retrospective study of patients with cardiomyopathy and PH-LHD, an elevated DPG was not associated with worse survival. PMID:25453535

    The authors report the case of a 74-year-old man, with a history of chronic obstructive pulmonary disease (COPD), GOLD grade 3, stable for the past two decades, who was admitted to our center with severe right heart failure. The chest radiograph showed moderate heart enlargement mainly of the right atrium and pulmonary artery, similar to previous chest radiographs in the previous 20 years. The transthoracic echocardiogram showed a pulmonary artery aneurysm (PAA), dilatation of the right chambers with pulmonary artery systolic pressure of 52 mmHg, and preserved right ventricular systolic function. A thoracic computed tomography scan confirmed the presence of a giant PAA 72 mm in diameter. The patient was started on high-dose diuretics, with significant clinical improvement. After optimization of medical therapy right heart catheterization was carried out with the patient in optimal clinical condition, which revealed mild precapillary pulmonary hypertension with a mean pulmonary artery pressure of 26 mmHg. On the basis of the clinical and imaging findings a stable, giant, high-pressure, PAA was diagnosed secondary to pulmonary hypertension induced by COPD, with a 20-year follow-up without need for surgical repair, which helped in our decision to maintain medical surveillance. The recent onset of heart failure is explained by the unfavorable evolution of COPD. This case may change the attitude expressed in previous studies favoring the choice of an invasive approach to treat giant high-pressure PAAs, instead supporting the maintenance of medical treatment.

    The chronic obstructive pulmonary disease has become a disease of public health importance. Among the various risk factors, smoking remains the main culprit. In addition to airway obstruction, the presence of intrinsic positive end expiratory pressure, respiratory muscle dysfunction contributes to the symptoms of the patient. Perioperative management of these patients includes identification of modifiable risk factors and their optimisation. Use of regional anaesthesia alone or in combination with general anaesthesia improves pulmonary functions and reduces the incidence of post-operative pulmonary complications. PMID:26556916

    Prevalence of pulmonary arterial hypertension (PAH) was studied by Echocardiography and Doppler in 43 splenectomised patients with various disorders 1-20 years after splenectomy. PAH was detected only in thalassemia major, intermedia, hereditary sphereocytosis and myelofibrosis groups comprising a total of 21 patients. Six patients out of 21 was found to have PAH with mean pulmonary arterial pressure of 46.28 ± 28.17 mmHg. Twenty one controls having similar duration and type of disease also were assessed for PAH in this case control study 3/21 had PAH in this control group. The difference in number of patients showing pulmonary hypertension between case and control was not statistically significant (chi-square test p = 0.29-though the difference in pulmonary arterial pressure between case and control were significantly different (t-test p<0.0029) with control group showing a mean pulmonary arterial pressure of 25 ± 19 mmHg.Platelet count in the splenectomised group was significantly higher (p = 0.0029) than the controls. Pulmonary thromboembolism was equally high in the PAH patients with and without splenectomy. Patients undergoing splenectomy due to trauma, immune thrombocytopenia, sideroblastic anemia, extra hepatic portal hypertension, autoimmune hemolytic anemia did not show PAH after splenectomy even years after the procedure PAH following splenectomy is common after certain disorders and control patients with these diseases have tendency to develop PAH even without splenectomy. Pulmonary thromboembolism may be an important pathophysiological mechanism leading to this condition. Patients having hemolytic anemia and myelofibrosis should have regular evaluation of pulmonary arterial pressure whether he/she has been splenectomised or not. This is particularly important as availability of phosphodiesterase inhibitors like sildenafil allows one to manage these cases. PMID:23100991

    Myeloproliferative neoplasm (MPN) transformed to acute myeloid leukemia (MPN-AML), MPN in accelerated phase (MPN-AP), and high-risk primary myelofibrosis (PMF) are associated with a poor response to therapy and very short survival. Several reports have suggested clinical activity of hypomethylating agents in these patients. We conducted a retrospective study of 21 patients with MPN-AML, 13 with MPN-AP and 11 with DIPSS-plus high-risk PMF treated with decitabine at our institution over the last 7 years and evaluated their clinical outcomes. Six patients (29%) with MPN-AML responded to decitabine (3 CR, 2 CRi, and 1 PR); median response duration was 7 months. The median overall survival (OS) was significantly higher in those who responded (10.5 vs 4 months). Among patients with MPN-AP, 8 patients (62%) benefited; the median response duration was 6.5 months. The median OS was 11.8 months in responders vs 4.7 months in non-responders. Among patients with DIPSS-plus high-risk PMF, 9 (82%) benefited; the median response duration was 9 months. The median OS was 32 months in responders vs 16.3 months in non-responders. Decitabine is a viable therapeutic option for patients with MPN-AML, MP-AP and high-risk PMF. Prospective clinical studies combining decitabine with other clinically active agents are needed to improve overall outcome. PMID:26183878

    In longitudinal studies of traumatic stress, it is particularly important to examine the data for any differences between those who drop out and those who continue to participate, because reluctance to participate might reflect symptoms of avoidance frequently seen in posttraumatic stress disorder (PTSD). However, whether those who drop out are at high risk of PTSD remains unclear. Over a 25-month period, 188 consecutive patients with motor vehicle accident (MVA)-related injuries admitted emergently were enrolled and followed for 4 to 6 weeks. Baseline characteristics were compared between subjects who did and did not participate in the follow-up study. At 4 to 6 weeks, 66 (35.1%) of the participants had dropped out. Bivariate analyses revealed that those who dropped out were likely to be men, alcohol drinkers, smokers, and unconscious just after MVA and to have fewer years of education, less severe injuries, less posttraumatic symptoms, and lower cooperativeness as assessed by the Temperament and Character Inventory. Logistic regression analysis revealed that male sex, unconsciousness during MVA, low cooperativeness, and less severe injuries were significant predictors of dropout. The literature says that male sex and unconsciousness just after MVA might be protective factors against MVA-related PTSD, whereas low cooperativeness is a risk factor for general mental problems. To summarize, it is expected that those who drop from the follow-up are unlikely to have MVA-related PTSD, but might have mental problems independent of injury. PMID:18555061

    Pulmonary hypertension remains a challenging condition to diagnose and manage. Decentralized care for pulmonary arterial hypertension (PAH) has led to shortcomings in the diagnosis and management of PAH. The Pulmonary Hypertension Association-sponsored Pulmonary Hypertension Care Center program is designed to recognize specialty centers capable of providing multidisciplinary and comprehensive care of PAH. Ideally, Pulmonary Hypertension Care Centers will comanage PAH patients with community-based practitioners and address the growing needs of this emerging population of long-term PAH patients.

    The purpose of this study was to create a prognostic model for distant metastasis in patients with locally advanced NPC who accept concurrent chemotherapy combined with intensity-modulated radiotherapy (CCRT) to identify high-risk patients who may benefit from neoadjuvant chemotherapy (NACT). A total of 881 patients with newly-diagnosed, non-disseminated, biopsy-proven locoregionally advanced NPC were retrospectively reviewed; 411 (46.7%) accepted CCRT and 470 (53.3%) accepted NACT followed by CCRT. Multivariate analysis demonstrated N2–3 disease, plasma Epstein–Barr virus (EBV) DNA > 4000 copies/mL, serum albumin ≤46 g/L and platelet count >300 k/cc were independent prognostic factors for distant metastasis in the CCRT group. Using these four factors, a prognostic model was developed, as follows: 1) low-risk group: 0–1 risk factors; and 2) high-risk group: 2–4 risk factors. In the high-risk group, patients who accepted NACT + CCRT had significantly higher distant metastasis-free survival and progression-free survival rates than the CCRT group (P = 0.001; P = 0.011). This simple prognostic model for distant metastasis in locoregionally advanced NPC may facilitate with the selection of high-risk patients who may benefit from NACT prior to CCRT. PMID:26564805

It has not been established whether chemotherapy should be delayed in patients with spontaneous TLS, and several studies have shown poor prognoses in this group. This retrospective study evaluated the efficacy and safety of continuous venovenous hemofiltration (CVVH) with prephase chemotherapy using the modified LMB-89 regimen in patients with Burkitt lymphoma and leukemia (BL/L) at a high risk of developing TLS from February 1998 to February 2007. The chemotherapy regimen was followed by the modified LMB-89 protocol. CVVH was applied to all patients before prephase chemotherapy or within 2 h of chemotherapy. The median follow-up was 19.7 months (range 1-97.8). Eight patients had Burkitt lymphoma and three had Burkitt leukemia; their median age was 48 years. The international prognostic indices were >3 for all patients. Seven patients had spontaneous TLS and four patients were at a high risk of TLS. CVVH was continued for 109 h (range 70.5-157.5). No patient had fatal metabolic complications related to TLS. Renal function had recovered fully before induction chemotherapy in all but one patient. The 1-year event-free survival and overall survival rates were both 82%. In conclusion, chemotherapy combined with CVVH might be effective and safe in patients with advanced Burkitt lymphoma and leukemia at a high risk of developing TLS. PMID:19030857

    Purpose: To analyze prognostic factors in patients with high-risk prostate cancer treated with dose-escalated external-beam radiation therapy (EBRT) and androgen deprivation (ADT). Methods and Materials: Between 1998 and 2008 at University of Michigan Medical Center, 718 men were consecutively treated with EBRT to at least 75 Gy. Seven definitions of high-risk prostate cancer, applying to 11-33% of patients, were evaluated. Biochemical failure (BF), salvage ADT use, metastatic progression, and prostate cancer-specific mortality (PCSM) were estimated by the Kaplan-Meier method and Cox proportional hazards regression. Results: Each high-risk definition was associated with increased BF (hazard ratio [HR] 2.8-3.9, p < 0.0001), salvage ADT use (HR 3.9-6.3, p < 0.0001), metastasis (HR 3.7-6.6, p < 0.0001), and PCSM (HR 3.7-16.2, p < 0.0001). Furthermore, an increasing number of high-risk features predicted worse outcome. Adjuvant ADT yielded significant reductions in both metastases (HR 0.19-0.38, p < 0.001) and PCSM (HR 0.38-0.50, p < 0.05) for all high-risk definitions (with the exception of clinical Stage T3-4 disease) but improved BF only for those with elevated Gleason scores (p < 0.03, HR 0.25-0.48). When treated with ADT and dose-escalated EBRT, patients with Gleason scores 8 to 10, without other high-risk features, had 8-year freedom from BF of 74%, freedom from distant metastases of 93%, and cause-specific survival of 92%, with salvage ADT used in 16% of patients. Conclusion: Adjuvant ADT results in a significant improvement in clinical progression and PCSM across multiple definitions of high-risk disease even with dose-escalated EBRT. There is a subset of patients, characterized by multiple high-risk features or the presence of Gleason Pattern 5, who remain at significant risk for metastasis and PCSM despite current treatment.

    The National Emphysema Treatment Trial used a multidisciplinary team approach to implement the maximum medical care protocol, including adjustment of medications and outpatient pulmonary rehabilitation for all patients and nutritional and psychological counseling as needed. This article discusses the benefits of such an approach in the care of the patient with chronic obstructive pulmonary disease. Team member roles complement each other and contribute to the goal of providing the highest-quality medical care. The primary focus of the team is to reinforce the medical plan and to provide patient education and support. This article reviews the elements of the initial patient assessment and the functional and nutritional assessment. Patient education focuses on medication use, recognition and management of chronic obstructive pulmonary disease exacerbation symptoms, smoking cessation, advance directives, and travel.

    Background: Remote ischemic preconditioning is a simple therapy that may reduce cardiac and kidney injury. We undertook a randomized controlled trial to evaluate the effect of this therapy on markers of heart and kidney injury after cardiac surgery. Methods: Patients at high risk of death within 30 days after cardiac surgery were randomly assigned to undergo remote ischemic preconditioning or a sham procedure after induction of anesthesia. The preconditioning therapy was three 5-minute cycles of thigh ischemia, with 5 minutes of reperfusion between cycles. The sham procedure was identical except that ischemia was not induced. The primary outcome was peak creatine kinase–myocardial band (CK-MB) within 24 hours after surgery (expressed as multiples of the upper limit of normal, with log transformation). The secondary outcome was change in creatinine level within 4 days after surgery (expressed as log-transformed micromoles per litre). Patient-important outcomes were assessed up to 6 months after randomization. Results: We randomly assigned 128 patients to remote ischemic preconditioning and 130 to the sham therapy. There were no significant differences in postoperative CK-MB (absolute mean difference 0.15, 95% confidence interval [CI] −0.07 to 0.36) or creatinine (absolute mean difference 0.06, 95% CI −0.10 to 0.23). Other outcomes did not differ significantly for remote ischemic preconditioning relative to the sham therapy: for myocardial infarction, relative risk (RR) 1.35 (95% CI 0.85 to 2.17); for acute kidney injury, RR 1.10 (95% CI 0.68 to 1.78); for stroke, RR 1.02 (95% CI 0.34 to 3.07); and for death, RR 1.47 (95% CI 0.65 to 3.31). Interpretation: Remote ischemic precnditioning did not reduce myocardial or kidney injury during cardiac surgery. This type of therapy is unlikely to substantially improve patient-important outcomes in cardiac surgery. Trial registration: ClinicalTrials.gov, no. NCT01071265. PMID:26668200

    Risk stratification and treatment intensification, based on minimal residual disease (MRD) mensurement, changed the prognosis of pediatric patients with acute lymphocytic leukemia (ALL). The main aim of this study was to investigate whether peripheral blood (PB) MRD measurement at day 8 (D8) could predict the risk stratification category determined by bone marrow (BM) MRD at day 15 (D15). The study was performed prospectively, in a cohort of 40 children with B-lineage ALL, adopting the protocol of the Brazilian Cooperative Group of the Treatment Childhood Leukemia (GBTLI-2009). MRD was detected by flow cytometry (FC) using a simplifed panel that can reliably identify MRD at early phases of induction therapy. Upon diagnosis, the proportion of low and high-risk patients, was 24:16 (60%:40%). The main result of our study demonstrated the potential of D8 MRD in anticipating of week the risk stratification of high-risk patients as determined by D15 BM MRD. In these patients D8 MRD level of 1% was able to segregate high risk fast responders from high risk slow responders (p = 0.0097). This result could represent an opportunity for early treatment intensification, as already performed in some protocols. PMID:27526794

    Background Pulmonary hypertension (PH) is a common finding in patients with chronic fibrosing idiopathic interstitial pneumonias (IIP). Little is known about the response to pulmonary vasodilator therapy in this patient population. COMPERA is an international registry that prospectively captures data from patients with various forms of PH receiving pulmonary vasodilator therapies. Methods We retrieved data from COMPERA to compare patient characteristics, treatment patterns, response to therapy and survival in newly diagnosed patients with idiopathic pulmonary arterial hypertension (IPAH) and PH associated with IIP (PH-IIP). Results Compared to patients with IPAH (n = 798), patients with PH-IIP (n = 151) were older and predominantly males. Patients with PH-IIP were treated predominantly with phosphodiesterase-5 inhibitors (88% at entry, 87% after 1 year). From baseline to the first follow-up visit, the median improvement in 6MWD was 30 m in patients with IPAH and 24.5 m in patients with PH-IIP (p = 0.457 for the difference between both groups). Improvements in NYHA functional class were observed in 22.4% and 29.5% of these patients, respectively (p = 0.179 for the difference between both groups). Survival rates were significantly worse in PH-IIP than in IPAH (3-year survival 34.0 versus 68.6%; p<0.001). Total lung capacity, NYHA class IV, and mixed-venous oxygen saturation were independent predictors of survival in patients with PH-IIP. Conclusions Patients with PH-IIP have a dismal prognosis. Our results suggest that pulmonary vasodilator therapy may be associated with short-term functional improvement in some of these patients but it is unclear whether this treatment affects survival.

    Sarcoidosis is a rare disease, especially in the preschool age group where it usually presents with eye, joint, and skin involvement sparing the lungs. Multiple treatment regimes have been described with oral prednisolone being the usual first line treatment. We describe a case of a 4-year-old boy presenting with pulmonary sarcoidosis with no other organ involvement. The child was successfully managed with pulse intravenous methylprednisolone followed by oral prednisolone and has had a good outcome. This case reports a rare presentation of preschool sarcoidosis as well as the novel and successful use of pulse methylprednisolone in paediatric pulmonary sarcoidosis. PMID:26120005

    Idiopathic dilatation of the pulmonary artery (IDPA) is a rare congenital heart disease. It has been described for almost one hundred years, and numerous definitions have been proposed. The IDPA diagnostic criteria have not been updated for years. Secondary to primary disease, pulmonary artery aneurism was recognised as a lethal defect; however, long-term follow-up of patients with IDPA has not been well researched. Thus, indications to medical or surgical treatment are not evidence based. Here, we present a rare case of a 54-year-old patient with IDPA, who remained under observation for 36 years without surgical intervention. PMID:26855651

    Objective: Epidural anesthesia is a central neuraxial block technique with many applications. It is a versatile anesthetic technique, with applications in surgery, obstetrics and pain control. Its versatility means it can be used as an anesthetic, as an analgesic adjuvant to general anesthesia, and for postoperative analgesia. Off pump coronary artery bypass (OPCAB) surgery triggers a systemic stress response as seen in coronary artery bypass grafting (CABG). Thoracic epidural anesthesia (TEA), combined with general anesthesia (GA) attenuates the stress response to CABG. There is Reduction in levels of Plasma epinephrine, Cortisol and catecholamine surge, tumor necrosis factor-Alpha(TNF ά), interleukin-6 and leucocyte count. Design: A prospective randomised non blind study. Setting: A clinical study in a multi specialty hospital. Participants: Eighty six patients. Material and Methods/intervention: The study was approved by hospital research ethics committee and written informed consent was obtained from all patients. Patients were randomised to receive either GA plus epidural (study group) or GA only (control group). Inclusion Criteria (for participants) were -Age ≥ 70 years, Patient posted for OPCAB surgery, and patient with comorbidities (diabetes mellitus, chronic obstructive pulmonary disease, cerebrovascular disease, peripheral vascular disease, renal dysfunction). Serum concentration of Interlukin: – 6, TNF ά, cortisol, Troponin – I, CK-MB, and HsCRP (highly sensitive C reactive protein), was compared for both the group and venous blood samples were collected and compared just after induction, at day 2, and day 5 postoperatively. Time to mobilization, extubation, total intensive care unit stay and hospital stay were noted and compared. Independent t test was used for statistical analysis. Primary Outcomes: Postoperative complications, total intensive care unit stay and hospital stay. Secondary Outcome: Stress response. Result: Study group showed

    Physical inactivity is common in patients with chronic obstructive pulmonary disease (COPD) compared with age-matched healthy individuals or patients with other chronic diseases. Physical inactivity independently predicts poor outcomes across several aspects of this disease, but it is (at least in principle) treatable in patients with COPD. Pulmonary rehabilitation has arguably the greatest positive effect of any current therapy on exercise capacity in COPD; as such, gains in this area should facilitate increases in physical activity. Furthermore, because pulmonary rehabilitation also emphasizes behavior change through collaborative self-management, it may aid in the translation of increased exercise capacity to greater participation in activities involving physical activity. Both increased exercise capacity and adaptive behavior change are necessary to achieve significant and lasting increases in physical activity in patients with COPD. Unfortunately, it is readily assumed that this translation occurs naturally. This concise clinical review will focus on the effects of a comprehensive pulmonary rehabilitation program on physical activity in patients with COPD. Changing physical activity behavior in patients with COPD needs an interdisciplinary approach, bringing together respiratory medicine, rehabilitation sciences, social sciences, and behavioral sciences.

    Acute cytomegalovirus (CMV) infection occurs commonly in immunocompromised and immunocompetent patients, but is usually asymptomatic in the latter. Vascular events associated with acute CMV infection have been described, but are rare. Hence, such events are rarely reported in the literature. We report a case of pulmonary embolism secondary to acute CMV colitis in an immunocompetent 78-year-old man. The patient presented with fever and diarrhea. Colonic ulcers were diagnosed based on colonoscopy findings, and CMV was the proven etiology on pathological examination. The patient subsequently experienced acute respiratory failure. Pulmonary embolism was diagnosed based on the chest radiography and computed tomography findings. A diagnosis of acute CMV colitis complicated by pulmonary embolism was made. The patient was successfully treated with intravenous administration of unfractionated heparin and intravenous ganciclovir. PMID:27175121

    Given the low α/β ratio of prostate cancer, prostate hypofractionation has been tested through numerous clinical studies. There is a growing body of literature suggesting that with high conformal radiation therapy and even with more sophisticated radiation techniques, such as high-dose-rate brachytherapy or image-guided intensity modulated radiation therapy, morbidity associated with shortening overall treatment time with higher doses per fraction remains low when compared with protracted conventional radiation therapy to the prostate only. In high-risk prostate cancer patients, there is accumulating evidence that either dose escalation to the prostate or hypofractionation may improve outcome. Nevertheless, selected patients who have a high risk of lymph node involvement may benefit from whole-pelvic radiation therapy (WPRT). Although combining WPRT with hypofractionated prostate radiation therapy is feasible, it remains investigational. By combining modern advances in radiation oncology (high-dose-rate prostate brachytherapy, intensity modulated radiation therapy with an improved image guidance for soft-tissue sparing), it is hypothesized that WPRT could take advantage of recent results from hypofractionation trials. Moreover, the results from hypofractionation trials raise questions as to whether hypofractionation to pelvic lymph nodes with a high risk of occult involvement might improve the outcomes in WPRT. Although investigational, this review discusses the challenging idea of WPRT in the context of hypofractionation for patients with high-risk prostate cancer.

    Posaconazole tablets, a new oral formulation of posaconazole, can be effective when given as antifungal prophylaxis to neutropenic patients at high risk for invasive fungal infection (e.g., those with acute myelogenous leukemia or myelodysplastic syndrome). Such effectiveness might be specifically important to patients with poor oral intake because of nausea, vomiting, or chemotherapy-associated mucositis. This was a prospective, global study in high-risk patients to characterize the pharmacokinetics and safety profile of posaconazole tablets and to identify the dose of posaconazole tablets that would provide exposure within a predefined range of exposures (steady-state average concentration [area under the concentration-time curve/24 h] of ≥500 ng/ml and ≤2,500 ng/ml in >90% of patients). The study evaluated two sequential dosing cohorts: 200 mg posaconazole once daily (n = 20) and 300 mg posaconazole once daily (n = 34) (both cohorts had a twice-daily loading dose on day 1) taken without regard to food intake during the neutropenic period for ≤28 days. The exposure target was reached (day 8) in 15 of 19 (79%) pharmacokinetic-evaluable patients taking 200 mg posaconazole once daily and in 31 of 32 (97%) patients taking 300 mg posaconazole once daily; 300 mg posaconazole once daily achieved the desired exposure target. Posaconazole tablets were generally well tolerated in high-risk neutropenic patients. (This study has been registered at ClinicalTrials.gov under registration no. NCT01777763.) PMID:25049247

    Background Predicting the risk of tuberculosis (TB) in people living with HIV (PLHIV) using a single test is currently not possible. We aimed to develop and validate a clinical algorithm, using baseline CD4 cell counts, HIV viral load (pVL), and interferon-gamma release assay (IGRA), to identify PLHIV who are at high risk for incident active TB in low-to-moderate TB burden settings where highly active antiretroviral therapy (HAART) is routinely provided. Materials and Methods A prospective, 5-year, cohort study of adult PLHIV was conducted from 2006 to 2012 in two hospitals in Taiwan. HAART was initiated based on contemporary guidelines (CD4 count < = 350/μL). Cox regression was used to identify the predictors of active TB and to construct the algorithm. The validation cohorts included 1455 HIV-infected individuals from previous published studies. Area under the receiver operating characteristic (ROC) curve was calculated. Results Seventeen of 772 participants developed active TB during a median follow-up period of 5.21 years. Baseline CD4 < 350/μL or pVL ≥ 100,000/mL was a predictor of active TB (adjusted HR 4.87, 95% CI 1.49–15.90, P = 0.009). A positive baseline IGRA predicted TB in patients with baseline CD4 ≥ 350/μL and pVL < 100,000/mL (adjusted HR 6.09, 95% CI 1.52–24.40, P = 0.01). Compared with an IGRA-alone strategy, the algorithm improved the sensitivity from 37.5% to 76.5%, the negative predictive value from 98.5% to 99.2%. Compared with an untargeted strategy, the algorithm spared 468 (60.6%) from unnecessary TB preventive treatment. Area under the ROC curve was 0.692 (95% CI: 0.587–0.798) for the study cohort and 0.792 (95% CI: 0.776–0.808) and 0.766 in the 2 validation cohorts. Conclusions A validated algorithm incorporating the baseline CD4 cell count, HIV viral load, and IGRA status can be used to guide targeted TB preventive treatment in PLHIV in low-to-moderate TB burden settings where HAART is routinely provided to all PLHIV.

    Background Rapid response system (RRS) is a safety tool designed for early detection and intervention of a deteriorating patient on the general floor in the hospital. Obstructive sleep apnea (OSA) has been associated with significant cardiovascular complications. We hypothesized that patients with high-risk of OSA have higher rate of RRS events and intervention with positive airway pressure therapy in these patients can mitigate the RRS events. Methods As part of a clinical pathway, during a 15 month period, patients with BMI ≥ 30 kg/m2 in select medical services were screened with a validated sleep questionnaire. Patients were characterized as high or low risk based on the screening questionnaire. RRS rates were compared between the groups. Subsequently the impact of PAP therapy on RRS events was evaluated. Results Out of the 2,590 patients screened, 1,973 (76%) were identified as high-risk. RRS rates calculated per 1,000 admissions, were 43.60 in the High-Risk OSA group versus 25.91 in the Low-Risk OSA Group. The PAP therapy compliant group had significantly reduced RRS event rates compared to non-compliant group and group with no PAP therapy (16.99 vs. 53.40 vs. 56.21) (p < 0.01). Conclusion In a large cohort of patients at a tertiary care hospital, we show an association of increased rate of RRS events in high-risk OSA patients and reduction of the risk with PAP intervention in the compliant group.

    Pulmonary rehabilitation has been reported to be effective in patients with chronic obstructive pulmonary disease (COPD). To investigate the effect of a moderate period of pulmonary rehabilitation combined with inspiratory muscle training (IMT) in elderly patients with COPD, we instituted pulmonary rehabilitation for 60 weeks in five elderly patients (age: 65.4 +/- 3.7 SE years). IMT was performed for 15 min twice daily using a pressure threshold device. The inspiratory threshold was set at 15% of the maximal inspiratory pressure (PImax) of each individual. Maximal peak flow significantly increased from 3.0 +/- 0.6 (L/s) at baseline to 4.1 +/- 0.7 (L/s) after 12 weeks (p < 0.02) and was maintained at that level for 60 weeks. PImax increased significantly from 49.9 +/- 6.4 cmH2O at baseline to 67.3 +/- 3.0 cmH2O after 12 weeks (p < 0.05) and to 72.8 +/- 3.5 cmH2O (p < 0.02) after 60 weeks of rehabilitation. The 10-minute walking distance increased from 666.6 +/- 55.0 to 764.0 +/- 49.9 m (p < 0.05) after 12 weeks and was maintained at the same level. We conclude that pulmonary rehabilitation combined with IMT improves pulmonary function and inspiratory muscle strength in elderly patients with COPD between for 12 weeks after commencement, but occurs that no significant increase on lung function or 10-minute walking distance from 12 to 60 weeks. Respiratory muscle strength may further increase after 60 weeks. PMID:9430986

  18. “V-PLASTY”: a novel technique to reconstruct pulmonary valvular and annular stenosis in patients with right ventricular outflow tract obstruction

    PubMed Central

    2013-01-01

    Background The goal of repair of right ventricular outflow tract obstruction with or without Tetralogy of Fallot (TOF) is to eliminate valvular and/or subvalvular obstruction. However, this operation has a high risk of late complication of pulmonary insufficiency. In this study, we aimed to present early period results of our new technique that we call “V-Plasty” developed to prevent pulmonary insufficiency after pulmonary valve reconstruction in selected patients. Methods Between January 2006 and January 2010, we performed V-plasty for pulmonary valve reconstruction in 10 patients. Eight patients (5 males, 3 females) had TOF and 2 patients (1 male, 1 female) had atrial septal defect concomitant with pulmonary valve stenosis. Patient selection for V-plasty reconstruction was made due to the pulmonary valve anatomy and degree of stenosis. The mean follow-up time was 55.7 ± 16.2 months (ranging from 32 to 80 months). Results Functional capacity of the patients improved immediately after the surgery. There were no mortality and re-operation in follow-up period. Patients were followed up with echocardiography one week after the operation, at 1st, 6th, 12th months and annually. There was no pulmonary insufficiency. Conclusions Operative correction of the pulmonary outflow tract obstruction with or without TOF, frequently requires transannular enlargement because of the infundibular and/or annular-valvular obstruction. This conventional technique is usually a reason for late pulmonary insufficiency. In our study, we have not seen pulmonary insufficiency in early term follow-up period. Our early term results are encouraging, but long term follow-up results are needed with large case series. PMID:23537211

    Recent studies have conferred that the RAD51C and RAD51D genes, which code for the essential proteins involved in homologous recombination, are ovarian cancer (OC) susceptibility genes that may explain genetic risks in high-risk patients. We performed a mutation analysis in 171 high-risk BRCA1 and BRCA2 negative OC patients, to evaluate the frequency of hereditary RAD51C and RAD51D variants in Czech population. The analysis involved direct sequencing, high resolution melting and multiple ligation-dependent probe analysis. We identified two (1.2%) and three (1.8%) inactivating germline mutations in both respective genes, two of which (c.379_380insG, p.P127Rfs*28 in RAD51C and c.879delG, p.C294Vfs*16 in RAD51D) were novel. Interestingly, an indicative family cancer history was not present in four carriers. Moreover, the ages at the OC diagnoses in identified mutation carriers were substantially lower than those reported in previous studies (four carriers were younger than 45 years). Further, we also described rare missense variants, two in RAD51C and one in RAD51D whose clinical significance needs to be verified. Truncating mutations and rare missense variants ascertained in OC patients were not detected in 1226 control samples. Although the cumulative frequency of RAD51C and RAD51D truncating mutations in our patients was lower than that of the BRCA1 and BRCA2 genes, it may explain OC susceptibility in approximately 3% of high-risk OC patients. Therefore, an RAD51C and RAD51D analysis should be implemented into the comprehensive multi-gene testing for high-risk OC patients, including early-onset OC patients without a family cancer history.

    Gough, Andrea; Kaufman, Gerri

    Pulmonary tuberculosis (TB) is a common infectious disease and a major cause of illness and death throughout the world, particularly in developing countries. This article explores the difference between latent TB infection and active TB disease, and discusses the pharmacological management of TB and issues around adherence to medication. Although TB is usually managed by specialist teams it is essential that all practitioners have an understanding of the signs and symptoms of the disease to ensure early referral and accurate diagnosis.

    DEVOTE was designed to evaluate the cardiovascular safety of insulin degludec (IDeg) vs insulin glargine U100 (IGlar) in patients with T2D at high risk of cardiovascular events. DEVOTE is a phase 3b, multicenter, international, randomized, double-blind, active comparator-controlled trial, designed as an event-driven trial that would continue until 633 positively adjudicated primary events were accrued. The primary end point was the time from randomization to a composite outcome consisting of the first occurrence of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke. Patients with T2D at high risk of cardiovascular complications were randomized 1:1 to receive either IDeg or IGlar, each added to background therapies. This trial was designed to demonstrate statistical noninferiority of IDeg vs IGlar for the primary end point. DEVOTE enrolled 7,637 patients between October 2013 and November 2014 at 436 sites in 20 countries. Of these, 6,506 patients had prior cardiovascular disease or chronic kidney disease, and the remainder had multiple cardiovascular risk factors. DEVOTE was designed to provide conclusive evidence regarding the cardiovascular safety of IDeg relative to IGlar in a high-risk population of patients with T2D. PMID:27595693

  2. A retrospective study of focal segmental glomerulosclerosis: clinical criteria can identify patients at high risk for recurrent disease after first renal transplantation

    PubMed Central

    2013-01-01

    Background Focal segmental glomerulosclerosis (FSGS) is a frequent cause of end-stage renal disease. Renal transplantation in patients with FSGS is often complicated by disease recurrence, which is associated with poor outcome. There are no tests that reliably predict recurrence of FSGS after transplantation. The aim of this study was to evaluate if clinical criteria can identify patients at high risk for recurrent disease. Methods We retrospectively studied 94 patients who received a first renal transplant at a median age of 37 years (range 5–69 years). Patients were assigned to one of three groups: familial or genetic FSGS (group I; n=18), secondary FSGS (group II; n=10) and idiopathic FSGS (group III; n=66). Pretransplant clinical characteristics were analyzed to determine predictors of a recurrence after transplantation. Results FSGS only recurred in patients with idiopathic FSGS (group III; 42%). Patients with a recurrence had a significantly lower serum albumin, higher 24-hour proteinuria and higher estimated glomerular filtration rate at diagnosis. Serum albumin at diagnosis was the only independent predictor of a recurrence in patients with idiopathic FSGS. Patients with recurrent FSGS had more acute rejection episodes (54% vs. 27%, P =0.02) and lower five year graft survival compared to patients without a recurrence (50 vs. 82%, P <0.01). Conclusions Clinical criteria allow identification of patients at high risk of recurrent FSGS after renal transplantation. This information can be used in the counseling and management of patients with FSGS. PMID:23433074

    Nocardia spp. are bacteria of low virulence that cause infection classically in immunocompromised hosts with the lungs as the primary site of infection in the majority of cases. Patients with cystic fibrosis have pulmonary disease characterized by frequent and progressive bacterial infections. Reports of Nocardia spp. isolation in CF are rare in the literature and may represent colonization or active infection, the significance and optimal treatment of which are unknown. We report the second case to date of Nocardia transvalensis pulmonary infection in an immunocompetent patient with CF and the first in a child under the age of eighteen. PMID:25960909

    Purpose: This pilot study investigates the role of DOC-2/DAB2 Interacting Protein (DAB2IP) and enhancer of zeste homolog 2 (EZH2) as prognostic biomarkers in high-risk prostate cancer patients receiving definitive radiation therapy. Methods and Materials: Immunohistochemistry was performed and scored by an expert genitourinary pathologist. Clinical endpoints evaluated were freedom from biochemical failure (FFBF), castration resistance–free survival (CRFS), and distant metastasis–free survival (DMFS). Log-rank test and Cox regression were used to determine significance of biomarker levels with clinical outcome. Results: Fifty-four patients with high-risk prostate cancer (stage ≥T3a, or Gleason score ≥8, or prostate-specific antigen level ≥20 ng/mL) treated with radiation therapy from 2005 to 2012 at our institution were evaluated. Nearly all patients expressed EZH2 (98%), whereas 28% of patients revealed DAB2IP reduction and 72% retained DAB2IP. Median follow-up was 34.0 months for DAB2IP-reduced patients, 29.9 months for DAB2IP-retained patients, and 32.6 months in the EZH2 study. Reduction in DAB2IP portended worse outcome compared with DAB2IP-retained patients, including FFBF (4-year: 37% vs 89%, P=.04), CRFS (4-year: 50% vs 90%, P=.02), and DMFS (4-year: 36% vs 97%, P=.05). Stratified EZH2 expression trended toward significance for worse FFBF and CRFS (P=.07). Patients with reduced DAB2IP or highest-intensity EZH2 expression exhibited worse FFBF (4-year: 32% vs 95%, P=.02), CRFS (4-year: 28% vs 100%, P<.01), and DMFS (4-year: 39% vs 100%, P=.04) compared with the control group. Conclusion: Loss of DAB2IP is a potent biomarker that portends worse outcome despite definitive radiation therapy for patients with high-risk prostate cancer. Enhancer of zeste homolog 2 is expressed in most high-risk tumors and is a less potent discriminator of outcome in this study. The DAB2IP status in combination with degree of EZH2 expression may be useful for

    Pulmonary fibrosis is a frequent manifestation of telomere syndromes. Telomere gene mutations are found in up to 25% and 3% of patients with familial disease and sporadic disease, respectively. The telomere gene TINF2 encodes an eponymous protein that is part of the shelterin complex, a complex involved in telomere protection and maintenance. A TINF2 gene mutation was recently reported in a family with pulmonary fibrosis. We identified a heterozygous Ser245Tyr mutation in the TINF2 gene of previously healthy female patient that presented with progressive cough due to pulmonary fibrosis as well as panhypogammaglobulinemia at age 52. Retrospective multidisciplinary evaluation classified her as a case of possible idiopathic pulmonary fibrosis. Telomere length-measurement indicated normal telomere length in the peripheral blood compartment. This is the first report of a TINF2 mutation in a patient with sporadic pulmonary fibrosis, which represents another association between TINF2 mutations and this disease. Furthermore, this case underlines the importance of telomere dysfunction and not telomere length alone in telomere syndromes and draws attention to hypogammaglobulinemia as a manifestation of telomere syndromes.

    Aim To determine the appropriate timing of cardiac troponin T (cTnT) measurement for the early triage of pulmonary embolism (PE) patients. Methods In this single-center prospective study, PE was confirmed in all patients using computed tomography. 104 consecutive patients were divided into three groups (high-risk, intermediate, and low-risk) based on their hemodynamic status and echocardiographic signs of right ventricular dysfunction. cTnT levels were measured on admission and then after 6, 24, 48, and 72 hours with threshold values greater than 0.1 ng/mL. Results Intermediate-risk PE patients had higher cTnT levels than low-risk patients already in the first measurement (P = 0.037). Elevated cTnT levels significantly correlated with disease severity after 6 hours (intermediate vs low risk patients, P = 0.016, all three groups, P = 0.009). Conclusion In hemodynamically stable patients, increased cTnT level on admission differentiated intermediate from low-risk patients and could be used as an important element for the appropriate triage of patients.

    Considering the importance of BRCA1, BRCA2, CHEK2 and TP53 in the development of hereditary early-onset breast and ovarian cancer and that the genetic susceptibility profile of the Northeast population from Brazil has never been analyzed, this study aimed to verify the frequency of mutations of clinical significance in these genes in high-risk hereditary breast and ovarian cancer (HBOC) syndrome patients from that region. DNA samples from 106 high-risk unrelated patients mostly from Bahia, the biggest state in the Northeast region, were analyzed. These patients underwent full BRCA1 gene sequencing, screening for common founder mutations in the BRCA2, CHEK2 and TP53 genes and genetic ancestry analysis with nine ancestry informative markers. The positive results were confirmed by two sequencing reactions. Three mutations of clinical significance were found: BRCA1 p.R71G (4.71%), 3450del4 (3.77%) and TP53 p.R337H (0.94%). The genetic ancestry analysis showed a high European ancestry contribution (62.2%) as well as considerable African (31.2%) and Amerindian (6.6%) ancestry contributions (r2=0.991); this degree of heterogeneity was also significant in the population structure analysis (r=0.604). This population is highly admixed with a different spectrum of genetic susceptibility, with the Galician founder mutation BRCA1 p.R71G accounting for 50% of all identified mutations in high-risk HBOC patients. TP53 p.R337H was also significantly frequent; thus, the combined screening of BRCA1/2 and TP53 should be offered to high-risk HBOC patients from Northeast Brazil. PMID:27081505

    Objectives The indications for post-mastectomy radiotherapy (PMRT) with T1-2 breast cancer and 1-3 positive axillary lymph nodes is still controversial. The purpose of this study was to investigate the role of PMRT in T1-2 breast cancer with 1-3 positive axillary lymph node. Methods We retrospectively reviewed the file records of 79 patients receiving PMRT and not receiving PMRT (618 patients). Results The median follow-up was 65 months. Multivariate analysis showed that PMRT was an independent prognostic factor of locoregional recurrence-free survival (LRFS) (P = 0.010). Subgroup analysis of patients who did not undergo PMRT showed that pT stage, number of positive axillary lymph nodes, and molecular subtype were independent prognostic factors of LRFS. PMRT improved LRFS in the entire group (P = 0.005), but did not affect distant metastasis-free survival (DMFS) (P = 0.494), disease-free survival (DFS) (P = 0.215), and overall survival (OS) (P = 0.645). For patients without PMRT, the 5-year LRFS of low-risk patients (0–1 risk factor for locoregional recurrence) of 94.5% was significantly higher than that of high-risk patients (2-3 risk factors for locoregional recurrence) (80.9%, P < 0.001). PMRT improved LRFS (P = 0.001) and DFS (P = 0.027) in high-risk patients, but did not improve LRFS, DMFS, DFS, and OS in low-risk patients. Conclusions PMRT is beneficial in patients with high risk of locoregional recurrence breast cancer patients with T1-2 and 1 to 3 positive nodes. PMID:25781605

    The aim of the study was to discuss the effect of intensive nursing education on the prevention of diabetic foot ulceration among patients at high risk for diabetic foot. One hundred eighty-five diabetes patients at high risk for foot diseases were enrolled in this study and provided with intensive nursing education, including individualized education about diabetes mellitus and diabetic foot diseases, instruction in podiatric care (the right way of washing the foot, the care of foot skin, appropriate choice of shoes and socks, intense examinations and records of feet by patients themselves every day, and the assistant management of calluses). Study subjects were followed up for 2 years. Once the foot ulceration developed, the inducing factors of foot ulceration were inquired about, the ulcers were evaluated, and the incidence of foot ulceration was analyzed before and after the intensive nursing education according to self-paired data. Results showed there were highly statistically significant improvements in the intensive treatment group compared with the control group in plasma glucose, blood pressure, and high-density lipoprotein cholesterol levels. More important is that intensive nursing education helps to prevent diabetic foot ulceration and to decrease the rate of amputation among patients at high risk for diabetic foot. PMID:25004241

    In patients with emphysema being evaluated for lung volume reduction surgery, Doppler echocardiography has been used to screen for pulmonary hypertension as an indicator of increased peri-operative risk. To determine the accuracy of this test, the present authors compared the results of right heart catheterisations and Doppler echocardiograms in 163 patients participating in the cardiovascular substudy of the National Emphysema Treatment Trial. Substudy patients had both catheterisation and Doppler echocardiography performed before and after randomisation. In 74 paired catheterisations and echocardiograms carried out on 63 patients, the mean values of invasively measured pulmonary artery systolic pressures and the estimated right ventricular systolic pressures were similar. However, using the World Health Organization's definitions of pulmonary hypertension, echocardiography had a sensitivity of 60%, specificity of 74%, positive predictive value of 68% and a negative predictive value of 67% compared with the invasive measurement. Bland-Altman analysis revealed a bias of 0.37 kPa with 95% limits of agreement from -2.5-3.2 kPa. In patients with severe emphysema, echocardiographic estimates of pulmonary artery pressures correlate very weakly with right heart catheterisations, and the test characteristics (e.g. sensitivity, specificity, etc.) of echocardiographic assessments are poor.

    Background The syndrome of combined pulmonary fibrosis and emphysema (CPFE) is a recently described entity associating upper-lobe emphysema and lower-lobe fibrosis. We sought to evaluate differences in pulmonary function between CPFE patients with and without airflow obstruction. Subjects and methods Thirty-one CPFE patients were divided into two groups according to the presence or absence of irreversible airflow obstruction based on spirometry (forced expiratory volume in 1 second/forced vital capacity <70% following inhalation of a β2-agonist) as follows: CPFE patients with airflow obstruction (CPFE OB+ group, n=11), and CPFE patients without airflow obstruction (CPFE OB− group, n=20). Pulmonary function, including respiratory impedance evaluated using impulse oscillometry and dynamic hyperinflation following metronome-paced incremental hyperventilation, was retrospectively analyzed in comparison with that observed in 49 chronic obstructive pulmonary disease (COPD) patients (n=49). Results In imaging findings, low-attenuation-area scores on chest high-resolution computed tomography, representing the degree of emphysema, were significantly lower in the CPFE OB− group than in the CPFE OB+ and COPD groups. In contrast, the severity of pulmonary fibrosis was greater in the CPFE OB− group than in the CPFE OB+ group. In pulmonary function, lung hyperinflation was not apparent in the CPFE OB− group. Impairment of diffusion capacity was severe in both the CPFE OB− and CPFE OB+ groups. Impulse oscillometry showed that respiratory resistance was not apparent in the CPFE OB− group compared with the COPD group, and that easy collapsibility of small airways during expiration of tidal breath was not apparent in the CPFE OB+ group compared with the COPD group. Dynamic hyperinflation following metronome-paced incremental hyperventilation was significantly greater in the COPD group than in the CPFE OB− group, and also tended to be greater in the CPFE OB+ group than

    OBJECTIVE: To evaluate the outcome of pregnancies in patients with complex pulmonary atresia, comparing those with and without previous radical surgical repair. DESIGN: A retrospective study of all pregnancies in women with complex pulmonary atresia registered on the Grown-up Congenital Heart Unit database between 1977 and 1994. SETTING: Referral centre for adolescents and adults with congenital heart disease. PATIENTS: Forty one pregnancies occurred in 15 patients. They were divided into two groups; group I, 26 pregnancies in nine patients before radical repair (cyanotic); group II, 15 pregnancies in seven women after radical surgical repair. RESULTS: In group I there were three terminations, 13 miscarriages, eight healthy children, and two neonatal deaths. Five children were born prematurely and all had low birthweights. In group II there were two miscarriages, 11 normal children, and two children with congenital heart disease. None was premature and all had normal birthweights. There were major complications in both groups: in group I there were two thromboembolic complications and one episode of heart failure; in group II there was one pulmonary embolism and one arrhythmic complication, five pregnancies in three patients were complicated by left ventricular failure that was persistent in one case and progressive in another, leading to death 13 months after delivery. CONCLUSIONS: Patients with complex pulmonary atresia, with or without surgical repair, who have no or mild symptoms, can have successful pregnancies. Surgical repair decreases fetal complications significantly. In both groups thrombotic disorders and heart failure must be prevented. Patients with residual systemic-pulmonary collaterals after surgical repair are particularly at risk of left ventricular failure. PMID:9290396

    Purpose: To evaluate the efficacy and toxicity of concurrent chemoradiation with paclitaxel and carboplatin in patients with high-risk cervical cancer. Methods and Materials: Patients after radical hysterectomy for cervical cancer, with at least 1 high-risk characteristic, were administered paclitaxel 135 mg/m{sup 2}, carboplatin area under the curve = 5 every 3 weeks for 3 cycles concomitant with radiation therapy as adjuvant treatment. Results: This prospective study enrolled 71 consecutive patients. Sixty-six patients (93%) completed the planned treatment. The majority of grade 3/4 neutropenia or nonhematologic toxicities were usually self-limited. Diarrhea grades 3/4 were observed in 4 patients (5.6%). One patient developed anaphylactic shock after infusion of paclitaxel. With a median follow-up of 57 months, recurrences occurred in 16 patients. Multivariable analysis indicated that common iliac lymph node involvement is an independent risk factor for disease recurrence (odds ratio 13.48; 95% confidence interval 2.93-62.03). In the intent-to-treat population (n=71), the estimated 5-year disease-free survival and overall survival rates were 77.3% and 80.3% respectively. In the per-protocol population (n=62), disease-free survival was 78.9% and overall survival was 83.9%. Conclusions: Concurrent chemoradiation with paclitaxel/carboplatin is well tolerated and seems to be effective for patients who undergo radical hysterectomy. Therefore, a prospective, randomized controlled study should be designed to evaluate efficacy of this approach for patients with high-risk cervical cancer.

    Introduction: In prostate cancer, higher radiation doses are often related to higher local control rates. However, the clinical effect of these higher doses on normal tissue toxicities is generally overlooked. We dosimetrically analyze sequential intensity modulated radiotherapy (IMRT) plans in high-risk prostate cancer patients and correlate them with acute and late normal tissue toxicities. Materials and Methods: Twenty-five high-risk prostate cancer patients were planned with three-dimensional conformal radiotherapy to a dose of 50 Gy delivered in 25 fractions in 5 weeks, followed by seven-field IMRT boost, to a dose of 24 Gy delivered in 12 fractions in 2.5 weeks, along with hormonal therapy. Acute and late toxicities were analyzed using Radiation Therapy Oncology Group toxicity criteria. Student's t-test was used for correlating doses received by normal tissues with toxicity grade. Five-year disease-free survival (DFS) and biochemical relapse-free survival (RFS) were evaluated using Kaplan–Meier analysis. Results: Median follow-up of patients was 65 months. Of 25 patients, two developed acute Grade 2 rectal toxicity. Only 1 patient developed acute Grade 2 bladder toxicity. Late Grade 2 and 3 rectal toxicity was seen in 2 and 1 patient, respectively. Late Grade 2 and 3 bladder toxicity was seen in 1 patient each. Grade 2 or more acute rectal toxicity correlated significantly with rectal volume receiving >70 Gy (P = 0.04). The 5-year DFS and biochemical RFS was 70.2% and 79.2%, respectively. One patient failed locally and seven failed at distant sites. Conclusion: Sequential IMRT with a dose of 74 Gy and maximum androgen blockade is well tolerated in high-risk patients in Indian setup with adequate control rates. PMID:27555679

    Shared decision making is a dynamic clinical process by which the provider assists the patient in choosing between more than one treatment option for a given condition. Here, we explore what the shared decision making and risk communication process could look like in the setting of a high-risk patient with clinical stage I non-small cell lung cancer who is potentially eligible for either segmentectomy or stereotactic body radiation therapy. We highlight clinical tools that can be used during the shared decision making and risk communication process in a stepwise manner to identify patient preferences and values to assist in making a tailored treatment decision.

    Chronic granulomatous disease (CGD) is a primary immunodeficiency caused by failure of superoxide production in phagocytic cells. The disease is characterised by recurrent infections and inflammatory events, frequently affecting the lungs. Improvement of life expectancy now allows most patients to reach adulthood. We aimed to describe the pattern of pulmonary manifestations occurring during adulthood in CGD patients. This was a retrospective study of the French national cohort of adult patients (≥16 years old) with CGD. Medical data were obtained for 67 adult patients. Pulmonary manifestations affected two-thirds of adult patients. Their incidence was significantly higher than in childhood (mean annual rate 0.22 versus 0.07, p=0.01). Infectious risk persisted despite anti-infectious prophylaxis. Invasive fungal infections were frequent (0.11 per year per patient) and asymptomatic in 37% of the cases. They often required lung biopsy for diagnosis (10 out of 30). Noninfectious respiratory events concerned 28% of adult patients, frequently associated with a concomitant fungal infection (40%). They were more frequent in patients with the X-linked form of CGD. Immune-modulator therapies were required in most cases (70%). Respiratory manifestations are major complications of CGD in adulthood. Noninfectious pulmonary manifestations are as deleterious as infectious pneumonia. A specific respiratory monitoring is necessary. PMID:25614174

In seven elective surgical patients, the PA double port catheter with the second PA port 1 cm proximal to the balloon was inserted. The two PA ports, connected to identical pressure measuring systems, provided the pulmonary arterial pressures (Ppa) distal and proximal to the balloon. After general anesthesia was stabilized, the two Ppas were measured simultaneously during a PA occlusion maneuver during 10 s of apnea. The instant of occlusion was determined precisely as the time when the two Ppa traces sharply diverged. A single exponential equation was fitted to the segment of distal Ppa tracing starting 0.3 s after the instant of occlusion. Ppc was determined as the value of the exponential fit extrapolated to time 0. In six of seven patients, PA occlusion occurred consistently in the early systolic phase regardless of the timing of balloon inflation. Mean Ppa, Ppc, and pulmonary arterial wedge pressure were 16.6, 11.8, and 7.6 torr. The ratio of venous to total resistance ranged from 0.37 to 0.54 (mean:0.46). We conclude that this technique is clinically feasible and valuable in precise definition of the instant of PA occlusion. By defining PA occlusion consistently, this technique can provide reliable Ppc estimation in the clinical settings. PMID:8250302

    Several federal bodies provide ongoing analyses of the Medicare DRG prospective hospital payment system. Many states are using DRG prospective "all payor systems" for hospital reimbursement (based on the federal model). In All Payor Systems, Medicare, Medicaid, Blue Cross and other commercial insurers pay by the DRG mode; New York State has been All Payor since 1/1/88. This study simulated DRG All Payor methods on a large sample (n = 1,662) of pulmonary medicine patients for a two-year period using both federal and New York DRG reimbursement now in effect at our hospital. Medicare patients had (on average) a longer hospital length of stay and total hospital cost compared to patients from Medicaid, Blue Cross, and other commercial payors. Medicare patients also had a greater severity of illness compared to patients from Blue Cross Medicaid or other payors. All payors, however, (Medicaid, Blue Cross, Medicare and commercial insurers) generated significant financial risk under the DRG All Payor scheme. These data suggest that federal, state, and private payors may be underreimbursing for the care of the hospitalized pulmonary medicine patients using the DRG prospective hospital payment scheme. Health care financing policy, as demonstrated in this study, may limit both the access and quality of care for many pulmonary medicine patients in the future. PMID:2491799

    Patients with chronic thromboembolic pulmonary hypertension (CTEPH) experience debilitating symptoms that have a negative impact on their quality of life (QoL) in terms of physical capability, psychological wellbeing and social relationships. The use of QoL measurement tools is important in the assessment of treatment efficacy and in guiding treatment decisions. However, despite the importance of QoL, particularly to the patient, it remains under-reported in clinical studies of CTEPH therapy. CTEPH is unique in pulmonary hypertension in that it is potentially curable by surgery; however, a proportion of patients either have residual PH following surgery or are not operable. Although some patients with CTEPH have been treated off-label with pulmonary arterial hypertension-specific therapies, there have been few randomised controlled trials of these therapies in patients with CTEPH. Moreover, in these trials QoL outcomes are variably assessed, and there is little consistency in the tools used. Here we review the assessment of QoL in patients with CTEPH and the tools that have been used. We also discuss the effect of surgical intervention and medical therapies on QoL. We conclude that further studies of QoL in patients with CTEPH are needed to further validate the optimal QoL tools. PMID:27076580

    Prior studies have demonstrated the effectiveness of postoperative radiation therapy (RT) to the hip area following total hip replacement (THR) surgery in preventing the development of heterotopic bone formation in patients considered to be at high risk for development of this complication. Previously, patients received 20.00 Gy in 10 fractions (fx) over 2 weeks, beginning as soon postop as medically feasible (usually post-op day 2). In an effort to reduce hospital stay and risk of secondary malignancy, a prospective treatment program was initiated April 1982 using a reduced dose of 10.00 Gy in 5 fx over 5-7 days. As of February 1984, 46 consecutive hips determined to be at high risk were treated with this reduced dose. Prior studies have demonstrated that heterotopic bone is always radiographically evident by 8 weeks. Of the 46 hips, 41 had been evaluated with the minimum required 8 week follow-up X ray. Twenty-five of these hips, 61%, had a mean long term follow-up of 12 months. It historical control group, consisting of 54 consecutive high risk post-THR's, was shown to have a 68.5% incidence of heterotopic bone. The 20.00 Gy group, when RT was started by post-op day 5, demonstrated a 3.2% incidence, compared to 4.9% in the 10.00 Gy group. Complication rates were also comparable in the two RT groups, 19.4% and 7.3% respectively; 10.00 Gy is apparently as effective as 20.00 Gy in preventing heterotopic bone formation in high risk post-THR patients.

    Background The purpose of the study was to examine pulmonary hypertension (PH) patients’ quality of life (QOL) for the first time in Finland. Methods This was a non-interventional, cross-sectional study. The SF-36v2 questionnaire was sent to the PH patients who had been referred to or followed up on at the Helsinki University Central Hospital's pulmonary clinic for idiopathic pulmonary arterial hypertension, associated pulmonary arterial hypertension (APAH), or chronic thromboembolic PH (CTEPH). The patients were on pulmonary arterial hypertension (PAH) – specific drugs, were at least 18 years old, and had signed an informed consent. Results There were 62 patients who fulfilled the inclusion criteria, and 53% of respondents rated their health as moderate. Similarly, 55% of respondents rated their health status approximately the same compared to their situation 1 year ago. QOL was impaired in all other subscales, except for the mental health and mental component score. A majority of patients suffered from PH symptoms, which worsened their QOL. The greatest impact on their QOL was associated with a high World Health Organization (WHO) functional class (FC), poor performance in a 6-min walking test (6MWT), symptoms, oxygen therapy, elevated pro-brain natriuretic peptide, pericardial effusion, APAH etiology, and being retired from work. Conclusions The respondents had a reduced QOL, compared to the general population, in all other subscales, except for mental health. APAH patients had the worst QOL. Good results in functional capacity measures (WHO FC, 6MWT) were associated with a better QOL. Patients’ QOL can be improved by reducing the symptoms of PAH. PMID:26787306

    Aims To understand the perceptions, needs and experiences of patients with Idiopathic Pulmonary Fibrosis. Background Idiopathic pulmonary fibrosis is a progressive interstitial lung disease, with a mean life expectancy similar to some forms of cancer of 2–4 years from diagnosis. Unlike the cancer literature, which is rich with studies exploring the needs of their disease group, few publications exist on patient needs with this severe fibrotic lung disease. Design A Qualitative study which took place between 2007–2012. Methods Seventeen patients with a multidisciplinary team confirmed diagnosis of Idiopathic Pulmonary Fibrosis, with moderate to advanced disease severity and six of their informal carers were interviewed. An interview topic guide was developed by the researchers and service user group. The interviews were audio-recorded, semi-structured and took place at a regional respiratory and lung transplant centre in North West England. Interviews were transcribed verbatim and data analysed using Framework Analysis. Findings Three main themes were identified: ‘Struggling to get a diagnosis’; ‘Loss of the life I previously had’; and ‘Living with Idiopathic Pulmonary Fibrosis’. Patients reported struggling to get a diagnosis and coping with a life-limiting, rapidly progressive illness with no good treatment and few support structures. Conclusions There is an urgent need for a better understanding of the difficulties faced by people with Idiopathic Pulmonary Fibrosis and their carers. This can be used to develop better supportive care in the United Kingdom and ultimately improve the quality of life of these patients. PMID:25533573

    This retrospective study was undertaken to obtain information regarding the survival and toxicities after Yttrium-90 microspheres treatment in patients with primary liver malignancies. Baseline, treatment, and follow-up data were collected and analyzed for 21 patients treated with Yttrium-90 microspheres. Survival analysis was then performed. The results of this study showed that median survival for all the patients was 120 days. Twenty of 21 patients were categorized as high-risk with a median survival of 114 days. It was also found that one high-risk patient has survived 858 days with no recurrence of disease. Acute grade 3-5 toxicities were recorded for nine patients and consisted of elevations in AST and bilirubin, thrombocytopenia, abdominal pain, ascites, nausea, fatigue, and death. This study concluded that Yttrium-90 is a low-toxicity, outpatient alternative for individuals with liver cancer and without many options. The maximal value, however, may lie in the treatment of low-risk patients. PMID:19166244

    Background. Patient education is capable of reducing the risk for diabetic foot ulcers. However, specific education on foot ulcer prevention was either included in broader programs addressing different parts of diabetes care or provided with time- and resource-consuming curricula. The aim of the study is to assess the feasibility and efficacy of a brief educational program for the prevention of diabetic foot ulcers in high-risk patients. Methods. The study was performed on type 2 diabetic patients, randomized in a 1 : 1 ratio either to intervention or to control group. The principal endpoint was the incidence of foot ulcers. The intervention was a two-hour program provided to groups of 5–7 patients, including a 30-minute face-to-face lesson on risk factors for foot ulcers, and a 90-minute interactive session with practical exercises on behaviors for reducing risk. Results. The study was prematurely terminated due to a highly significant difference in outcome between the two treatment groups. The final sample was therefore composed of 121 patients. Six patients, all in the control group, developed ulcers during the 6-month follow-up (10% versus 0%, p = 0.012). Conclusions. A brief, 2-hour, focused educational program is effective in preventing diabetic foot ulcers in high-risk patients. PMID:26448748

    We investigated whether attempted percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) would improve the prognosis in patients with renal insufficiency at high risk of contrast-induced nephropathy (CIN). We analyzed 2,330 consecutive patients with renal insufficiency with or without CTOs who underwent coronary angiography or PCI from prospectively collected data. The long-term death and risk of CIN were evaluated among three groups: patients without CTOs (group A, n = 1,829), patients with un-attempted PCI for CTOs (group B, n = 142), and patients who underwent attempted PCI for CTOs (group C, n = 359). Overall, group B and group C (successful rate, 89%) patients had similar renal function and were not significantly associated with an increased risk of CIN (adjusted odds ratio [OR] = 0.88, 95% confidence interval [CI]: 0.41–1.93, P = 0.758). During a 2.33-year period (median), multivariate analysis demonstrated that attempted PCI for CTOs was independently associated with lower mortality (adjusted hazard ratio for death: 0.38, 95% CI: 0.18–0.83; P = 0.015). Attempted PCI for CTOs improved the long-term prognosis in patients with high-risk renal insufficiency and did not increase the risk of CIN. PMID:26899017

    In this Phase 2 study, we evaluated the efficacy of combination of 5-azacitidine (AZA), valproic acid (VPA), and all-trans retinoic acid (ATRA) in patients with high-risk acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). Treatment consisted of six cycles of AZA and VPA for 7 days, followed by ATRA for 21 days. Sixty-five patients were enrolled (median age, 72 years; 55 AML including 13 relapsed/refractory patients, 10 MDS; 30 unfavorable karyotypes). Best responses included 14 CR and 3 PR (26%), 75% of the responders and 36% of the non-responders achieving an erythroid response. Median overall survival (OS) was 12.4 months. Untreated patients had a longer OS than relapsed/refractory patients. In patients who fulfilled the 6 planned cycles, OS did not appear to depend on CR/PR achievement, suggesting that stable disease while on-treatment would be a surrogate for survival with this approach. During therapy, early platelet response and demethylation of the FZD9, ALOX12, HPN, and CALCA genes were associated with clinical response. Finally, there was no evidence for the restoration of an ATRA-induced differentiation during therapy. Epigenetic modulation deserves prospective comparisons to conventional care in patients with high-risk AML, at least in those presenting previously untreated disease and low blast count.

    No reliable identification of quiescent Crohn's disease (CD) patients with a high risk of relapse is available. The aim of this study was to develop a prognostic index to identify those patients. Untreated adult patients with quiescent disease (not induced by surgery) included in three phase III clinical trials were analysed retrospectively with respect to time to relapse. Nineteen factors related to biology, disease history, and topography were investigated. A relapse was defined as either a CD Activity Index (CDAI) > or = 200, a CDAI > or = 150 but over the baseline value by more than 100, or acute complications requiring surgery. The inclusion criteria were fulfilled by 178 patients. The median follow up was 23 months. The Cox model retained the following bad prognostic factors: age < or = 25 years, interval since first symptoms > 5 years, interval since previous relapse < or = 6 months, and colonic involvement (p < 0.001). Bootstrapping confirmed the variable selection. Patients were classified into three groups with an increasing risk of relapse (p < 0.001). The worst risk group was composed of patients presenting at least three of the four bad prognostic factors. These results make possible the design of clinical trials in quiescent CD patients with a high risk of relapse. PMID:8537053

    Phase-contrast magnetic resonance imaging (PC-MRI) offers a range of surrogate markers to quantify the hemodynamic changes associated with chronic thromboembolic pulmonary hypertension (CTEPH). Our aim was to noninvasively monitor effects of pulmonary vascular remodeling before and after endarterectomy (PEA) in patients with CTEPH by using PC-MRI. Fifty-seven consecutive patients (mean age 56.7 ± 16, 28 female) underwent PC-MRI before and after PEA as part of their peri-operative routine workup. Pulmonary artery (PA) maximum flow velocity (maxV), acceleration time/ejection time (AT/ET), distensibility [(PA maximum area - PA minimum area)/PA minimum area], mid-systolic flow deceleration (notch), and the timing of deceleration (notch ratio) were recorded. Mean PA pressure was obtained from standard right heart catheter procedures. maxV and AT/ET were decreased before PEA and significantly improved afterwards (60.8 ± 16 vs. 73.8 ± 19 cm/s, p = 0.007; 0.32 ± 0.06 vs. 0.36 ± 0.09, p = 0.0015). Surprisingly, distensibility did not change significantly (30 ± 19 vs. 26 ± 12%, p = 0.11). Forty-five patients (78%) had a systolic notch before PEA that persisted in only 10 (18%; p = 0.00001). Among patients with a persisting notch, the notch ratio did not significantly increase (1.3 ± 0.2 vs. 1.6 ± 1.5, p = 0.32). Our data show early PA reverse remodeling after PEA. Flow velocities increase while PA flow wave reflections represented by mid-systolic flow deceleration are abolished. In some patients a mid-systolic notch persists, suggesting increased downstream resistance as a consequence of small vessel arteriopathy. PMID:25519191

    Hematopoietic myeloid progenitors released into the circulation are able to promote vascular remodeling through endothelium activation and injury. Endothelial injury is central to the development of pulmonary arterial hypertension (PAH), a proliferative vasculopathy of the pulmonary circulation, but the origin of vascular injury is unknown. In the present study, mice transplanted with BM-derived CD133+ progenitor cells from patients with PAH, but not from healthy controls, exhibited morbidity and/or death due to features of PAH: in situ thrombi and endothelial injury, angioproliferative remodeling, and right ventricular hypertrophy and failure. Myeloid progenitors from patients with heritable and/or idiopathic PAH all produced disease in xenografted mice. Analyses of hematopoietic transcription factors and colony formation revealed underlying abnormalities of progenitors that skewed differentiation toward the myeloid-erythroid lineage. The results of the present study suggest a causal role for hematopoietic stem cell abnormalities in vascular injury, right ventricular hypertrophy, and morbidity associated with PAH. PMID:22745307

    Aims: The deleterious nature of peripheral arterial disease (PAD) is compounded by a status of underdiagnosed and undertreated disease. We evaluated the prevalence and predictive factors of PAD in high-risk patients using the ankle-brachial index (ABI). Methods: The ABI was measured by general practitioners in France (May 2005–February 2006) in 5679 adults aged 55 years or older and considered at high risk. The primary outcome was prevalence of PAD (ABI strictly below 0.90). Results: In all, 21.3% patients had signs or symptoms suggestive of PAD, 42.1% had previous history of atherothrombotic disease and 36.6% had two or more cardiovascular risk factors. Prevalence of PAD was 27.8% overall, ranging from 10.4% in patients with cardiovascular risk factors only to approximately 38% in each other subgroup. Prevalence differed depending on the localization of atherothrombotic events: it was 57.1–75.0% in patients with past history of symptomatic PAD; 24.6–31.1% in those who had experienced cerebrovascular and/or coronary events. Regarding the classical cardiovascular risk factors, PAD was more frequent when smoking and hypercholesterolemia history were reported. PAD prevalence was also higher in patients with history of abdominal aortic aneurysm, renal hypertension or atherothrombotic event. Intermittent claudication, lack of one pulse in the lower limbs, smoking, diabetes and renovascular hypertension were the main factors predictive of low ABI. Conclusions: Given the elevated prevalence of PAD in high-risk patients and easiness of diagnosis using ABI in primary care, undoubtedly better awareness would help preserve individual cardiovascular health and achieve public health goals.

    The purpose of this study was to assess the clinical relevance, limitations and most common findings of axillary ultrasound and subsequent image-guided aspiration cytology in clinically node-negative breast cancer patients who are at high risk for axillary metastasis. Following institutional review board approval and Health Insurance Portability and Accountability Act (HIPAA) compliance, sonographic axillary surveys from 112 patients considered at high risk for axillary metastases were reviewed retrospectively for the following abnormal features: asymmetric cortical thickening/lobulations; loss or compression of the hyperechoic medullary region; absence of fatty hilum; abnormal lymph node shape; hypoechoic cortex; admixture of normal and abnormal appearing nodes; and increased peripheral blood flow. Patients with either normal or abnormal ultrasound exams, but negative cytology, underwent sentinel node mapping. Patients with abnormal ultrasound and positive cytology proceeded to complete axillary dissection. The number of positive nodes, the size of tumour deposits and the histological pattern of metastatic disease on the positive nodes were then correlated and compared with their corresponding sonographic abnormalities. Abnormalities related to the lymph node cortex were indicative of N1a disease. Features such as loss or compression of the hyperechoic medullary region, absence of fatty hilum, abnormal lymph node shape and increased peripheral blood flow were predictors of N2-3 disease. In conclusion, nodal sonographic characteristics of patients at high risk for metastases are useful predictors of tumour burden in the axilla. When combined with the results from aspiration cytology, these findings could modify the surgical approach to the axilla, eliminating the need for sentinel node mapping in a significant proportion of patients.

    Idiopathic pulmonary fibrosis (IPF) is associated with a fatal prognosis and manifests in patients over 60 years old who may have comorbidities. The prevalence and impact of comorbidities on the clinical course of IPF is unclear.This systematic literature review examined the prevalence of comorbidities and mortality associated with comorbidities in IPF patients. Relevant observational studies published in English from January 1990 to January 2015 identified via MEDLINE and EMBASE were included; bibliographies of articles were also searched.Among the 126 studies included, prevalence of pulmonary hypertension (PH) was 3-86%, 6-91% for obstructive sleep apnoea, 3-48% for lung cancer and 6-67% for chronic obstructive pulmonary disease (COPD). Nonrespiratory comorbidities included ischaemic heart disease (IHD) (3-68%) and gastro-oesophageal reflux (GER) (0-94%). Mortality was highest among patients with IPF and lung cancer. Most studies assessed relatively small samples of patients with IPF.PH, COPD, lung cancer, GER and IHD are significant comorbidities; differences in IPF severity, case definitions and patient characteristics limited the comparability of findings. The identification and prompt treatment of comorbidities may have a clinically significant impact on overall outcome that is meaningful for patients with IPF. PMID:26424523

    Cryptococcal infection is commonly seen in immunocompromised patients, although immunocompetent patients may also be infected. The pathogen’s portal of entry is the respiratory tract; however, the central nervous system is predominantly involved. Pulmonary involvement varies from interstitial and alveolar infiltrations to large masses, which are frequently first interpreted as lung neoplasm. The diagnosis of pulmonary cryptococcosis, in these cases, is frequently challenging, which, in most cases, requires histopathological examination. The authors report the case of a young female patient who presented a 20-day history of chest pleuritic pain and fever at the onset of symptoms. HIV serology was negative and CD4 count was normal. The imaging work-up was characterized by a huge opacity in the left inferior pulmonary lobe with a wide pleural base. Computed tomography showed a heterogeneous mass involving the bronchial tree. Mediastinal involvement was poor, and there was a splenomegaly. The patient underwent an exploratory thoracotomy and inferior lobectomy. The histopathological examination revealed a cryptococcoma. As the serum antigenemia was positive, the patient was scheduled for long-term treatment with fluconazole. The authors call attention to including the cryptococcal infection in the differential diagnosis of lung mass, mainly when localized in the lung bases in immunocompetent patients. PMID:26484332

    Consecutive patients admitted to a coronary care unit (CCU) during one year were studied. The diagnosis of acute myocardial infarction was not substantiated by our criteria in 206 of the patients discharged from the CCU. Of these, 193 were retrospectively followed up during one year. Seventeen of the patients (9%) died from cardiovascular causes during the 1-year period. Another 14 patients (7%) had a subsequent non-fatal acute myocardial infarction during the same period. The majority of the patients had coronary artery disease. Only 32 (17%) could be classified as non-coronary cases, and these had an excellent prognosis without any subsequent acute myocardial infarctions or deaths. The occurrence of transient ST-T shifts in serial electrocardiograms obtained during the first 3 days in hospital selected a subgroup of patients who had a high risk for subsequent non-fatal acute myocardial infarction and/or cardiovascular death. This high risk subgroup provides a basis for more aggressive diagnostic and therapeutic intervention. Images PMID:465239

    Several small-scale studies have reported pulmonary toxicity among patients with diffuse large B-cell lymphoma (DLBCL) receiving rituximab-containing chemotherapy, though whether the use of rituximab predisposes to interstitial pneumonia (IP) remains unclear. This retrospective study was intended to identify the characteristics and risk factors of IP in patients with DLBCL. Between 2000 and 2009, 529 consecutive patients with DLBCL receiving first-line tri-weekly COP- or CHOP-based chemotherapy with or without rituximab were enrolled as subjects. IP was defined as diffuse pulmonary interstitial infiltrates found on computed tomography scans in conjunction with respiratory symptoms. IP was observed in 26 patients (4.9%), six of whom were confirmed with Pneumocystis jirovecii pneumonia. The median number of chemotherapy courses before IP was four cycles. Using multivariate analysis, absolute lymphocyte count less than 1×10(9)/l at diagnosis [odds ratio (OR) 2.75, p=0.014] and the addition of rituximab to chemotherapy (OR 4.56, p=0.003) were identified as independent risk factors for IP. In conclusion, the incidence of IP is increased in patients with DLBCL receiving rituximab-containing chemotherapy. Specific subgroups with lymphopenia at diagnosis may justify close scrutiny to detect pulmonary complications. PMID:21647583

    Background: Sildenafil, a phosphodiestase type 5 inhibitor, was approved in 2005 for the treatment of pulmonary arterial hypertension (PAH) in adults and is commonly used off-label for pediatric patients. Little is known, however, about sildenafil’s side effects in this population. Methods: Single institution, longitudinal survey-based study performed in an outpatient pediatric cardiology clinic. Pediatric patients on sildenafil [alone or in combination with other pulmonary hypertension (PH) therapies] completed questionnaires regarding frequency of vascular, gastrointestinal, neurologic, and hematologic side effects. Results: Between January 2011 and May 2014, 66 pediatric patients with PH on sildenafil filled out 214 surveys, 32 patients (96 surveys) on monotherapy, and 43 patients (118 surveys) on sildenafil plus an endothelin receptor antagonist (ERA) (bosentan or ambrisentan) and/or a prostacyclin (epoprostenol or treprostinil). Overall, 30% of respondents identified at least one side effect. For all patients on sildenafil, incidence of side effects by system was 37% gastrointestinal, 35% vascular, and 22% neurologic. For patients on sildenafil monotherapy, incidence of side effects by system was 24% gastrointestinal, 21% vascular, and 18% neurologic compared to patients on combination therapy who reported an incidence of 48% gastrointestinal, 45% vascular, and 25% neurologic. Conclusion: Incidence of vascular, gastrointestinal, and neurologic side effect in pediatric patients on sildenafil therapy for PAH was 30%. Side effects were more common in patients on combination therapy with an ERA and/or prostacyclin than in patients on sildenafil monotherapy. PMID:25806361

    Purpose: To determine efficacy and toxicities of postoperative concurrent chemoradiation using docetaxel in high-risk head and neck cancer. Methods and Materials: High-risk patients were enrolled 2-8 weeks after surgery. Treatment included 60 Gy for 6 weeks with weekly docetaxel 25 mg/m{sup 2} and erythropoietin alpha 40,000 U for hemoglobin {<=}12 g/dL. Primary endpoints included locoregional control (LC), disease-free survival (DFS), and patterns of failure (POF). Secondary endpoints were toxicity and quality of life. Results: Eighteen patients were enrolled (14 male, 4 female), aged 24-70 years (median, 55 years). Primary site included oropharynx = 7, oral cavity 8, hypopharynx = 1, and larynx = 2. Pathologic American Joint Committee on Cancer Stage was III = 3 patients, IV = 15 patients. High-risk eligibility included {>=}2 positive lymph nodes = 13, extracapsular extension = 10, positive margins = 8 (11 patients with two or more risk factors). Docetaxel was reduced to 20 mg/m{sup 2}/week after 5 patients had prolonged Grade 3 or higher mucositis. Overall, number of doses delivered was 2 of 6 = 1, 3 of 6 2, 4 of 6 = 2, 5 of 6 = 4, 6 of 6 = 9 patients. With median follow-up of 30 months (range, 5-66), 10 (56%) patients are alive and have no evidence of disease (NED); POF: three local recurrences (two with distant) and 1 distant only. One-year survival was 76%, median PFS and DFS had not been reached. Three-year LC was 82%. No Grade 3 or higher late toxicities were observed, although a few cases of prolonged mucositis and taste loss (>3 months) were seen, particularly at 25 mg/m{sup 2}/week. Conclusion: Postoperative radiation therapy with weekly docetaxel 20 or 25 mg/m{sup 2}/week for high-risk postoperative head and neck cancer caused intolerable mucosal toxicity, prompting early study termination. Further studies should consider 15 mg/m{sup 2}. Actuarial 3-year LC is 82%, similar to cisplatin-based chemoradiation regimens. Distant metastasis remains an

    The definition of pulmonary fungal infections (PFI) according to the EORTC-MSG criteria may lack diagnostic sensitivity due to the possible presentation of PFI with different radiological pictures. We evaluated the hypothesis to apply less restrictive radiological criteria to define PFI in patients with acute myeloid leukaemia (AML) submitted to chemotherapy. Overall, 73 consecutive episodes of pulmonary infiltrates associated to positive serum galactomannan test or fungal isolation or galactomannan detection from respiratory specimens were considered. CT scans acquired at the onset of symptoms (time-0) and within 4 weeks (time-1) were analysed to identify specific (group A) or aspecific radiological signs (group B). Pulmonary infiltrates fulfilled the EORTC-MSG criteria in 49 patients (group A), whereas in 24 patients (group B) they did not reach the criteria due to aspecific CT findings at time-0. Eleven of 21 (52.4%) patients of the group B evaluable for the evolution of the radiological findings fulfilled EORTC-MSG criteria at time-1. All the analysed clinical and mycological characteristics, response to antifungal therapy and survival were comparable in the two groups. Our study seems to confirm the possibility to extend the radiological suspicion of PFI to less restrictive chest CT findings when supported by microbiological criteria in high-risk haematological patients.

    A 28-year-old male was referred to our hospital with dyspnea. He was diagnosed as having chronic thromboembolic pulmonary hypertension, and a pulmonary endarterectomy (PEA) was performed. However, exertional dyspnea remained because of residual pulmonary hypertension; therefore, the patient was re-admitted to our hospital 1 year after PEA. We performed computed tomography and pulmonary angiography and found web and band lesions in the distal pulmonary artery with a high pulmonary artery pressure. Although further management was complicated because the patient had an anaphylactic shock to iodine-based contrast media, we eventually completed five sessions of balloon pulmonary angioplasty (BPA) using gadolinium contrast medium. His symptoms and hemodynamics dramatically improved after a series of BPA. After 15 months, mean pulmonary arterial pressure reduced from 67 mmHg to 20 mmHg, and subjective symptoms improved from stage Ⅳ to I as per the WHO classification system. BPA is a potential procedure for residual pulmonary hypertension after PEA and could be safely performed using gadolinium contrast medium for patients with iodine allergy. PMID:27141436

    Sildenafil improves the 6-min walking distance in patients with idiopathic pulmonary fibrosis (IPF) and right-sided ventricular systolic dysfunction.We analysed the previously unexplored role of sildenafil on vasoconstriction and remodelling of pulmonary arteries from patients with IPF and pulmonary hypertension (PH) ex vivo Pulmonary arteries from 18 donors without lung disease, nine IPF, eight PH+IPF and four PH patients were isolated to measure vasodilator and anti-contractile effects of sildenafil in isometric organ bath. Ventilation/perfusion was explored in an animal model of bleomycin lung fibrosis.Sildenafil relaxed serotonin (5-HT) pre-contracted pulmonary arteries in healthy donors and IPF patients and, to a lesser extent, in PH+IPF and PH. Sildenafil inhibited 5-HT dose-response contraction curve mainly in PH+IPF and PH, but not in healthy donors. Sildenafil did not impair the ventilation/perfusion mismatching induced by bleomycin. Pulmonary arteries from PH+IPF patients showed a marked expression of phosphodiesterse-5 and extracellular matrix components. Sildenafil inhibited pulmonary artery endothelial and smooth muscle cell to mesenchymal transition by inhibition of extracellular regulated kinases 1 and 2 (ERK1/2) and SMAD3 phosphorylation.These results suggest an absence of direct relaxant effect and a prominent anti-contractile and anti-remodelling role of sildenafil in PH+IPF pulmonary arteries that could explain the beneficial effects of sildenafil in IPF with PH phenotype.

    Background Whilst the majority of the patients with severe aortic stenosis can be directly addressed to surgical aortic valve replacement (AVR) or transcatheter aortic valve implantation (TAVI), in some instances additional information may be needed to complete the diagnostic workout. We evaluated the role of balloon aortic valvuloplasty (BAV) as a bridge-to-decision (BTD) in selected high-risk patients. Methods Between 2007 and 2012, the heart team in our Institution required BTD BAV in 202 patients. Very low left ventricular ejection fraction, mitral regurgitation grade ≥ 3, frailty, hemodynamic instability, serious comorbidity, or a combination of these factors were the main drivers for this strategy. We evaluated how BAV influenced the final treatment strategy in the whole patient group and in each specific subgroup. Results Mean logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE) was 23.5% ± 15.3%, age 81 ± 7 years. In-hospital mortality was 4.5%, cerebrovascular accident 1% and overall vascular complications 4% (0.5% major; 3.5% minor). Of the 193 patients with BTD BAV who survived and received a second heart team evaluation, 72.6% were finally deemed eligible for definitive treatment (25.4% for AVR; 47.2% for TAVI): 96.7% of patients with left ventricular ejection fraction recovery; 70.5% of patients with mitral regurgitation reduction; 75.7% of patients who underwent BAV in clinical hemodynamic instability; 69.2% of frail patients and 68% of patients who presented serious comorbidities. Conclusions Balloon aortic valvuloplasty can be considered as bridge-to-decision in high-risk patients with severe aortic stenosis who cannot be immediate candidates for definitive transcatheter or surgical treatment.

    We reviewed the records of 4 patients with pathologically diagnosed pulmonary cryptococcosis to determine whether there was any relationship between radiographic and pathological findings. The underlying disease were diabetes mellitus (patient 1), rheumatoid arthritis treated with glucocorticoids (patient 2), and adultonset T cell leukemia (patients 3 and 4). All radiographs showed multiple nodules, and patchy and localized infiltrates, which progressed to diffuse interstitial infiltration. According to Mark's classification, the pathological findings in patients 1 and 2 showed granulomatous pneumonia, those in patient 3 showed histiocytic pneumonia, and patient 4 had intercapillary cryptococci with no inflammatory response. The granuloma appeared larger in patient 1 than in patient 2. This concurred with the clinical findings, i.e. large granulomas formed in immunocompetent patients, and diffuse pulmonary infiltrates developed in those whose immune systems had been compromised. When a granuloma formed, roentgenograms showed a well defined nodular shadow, with some nodules developing in the cavity. When granuloma formation became unclear, roentgenograms tended to show localized-to-diffuse infiltration, or interstitial shadows. PMID:9071170

    OBJECTIVE: To determine the prevalence of nutritional deficiency among patients with pulmonary tuberculosis. METHODS: This was a cross-sectional study using data obtained from the Brazilian Case Registry Database and from the medical records of patients diagnosed with pulmonary tuberculosis (15-59 years of age) residing in one of the municipalities that make up the 16th Regional Health District of the state of Bahia. We calculated the incidence, lethality, and mortality rates, as well as the prevalence of nutritional deficiency, as evaluated by body mass index. Demographic, social, clinical, and epidemiological data were collected. RESULTS: Of the 72 confirmed cases of tuberculosis, 59 (81.9%) were in males, and 21 (29.2%) of the patients were in the 40-49 year age bracket. The majority (85.3%) described themselves as Mulatto or Black; 55.2% reported using alcohol; and approximately 90% were treated as outpatients. In the district and age bracket studied, the incidence of pulmonary tuberculosis was 30.6/100,000 population. Among the 72 patients, data regarding nutritional status was available for 34. Of those, 50% and 25%, respectively, presented nutritional deficiency at the beginning and at the end of treatment. No statistically significant differences were found between normal-weight and malnourished patients regarding the characteristics studied. CONCLUSIONS: The prevalence of nutritional deficiency was high among our sample of patients with pulmonary tuberculosis. This underscores the importance of nutritional follow-up for the assessment of tuberculosis treatment in the decision-making process regarding therapeutic interventions. PMID:24068270

    Each year in the U.S., 7.4 million surgical procedures involving the major vessels are performed. Many of our patients require multiple surgeries, and many of the procedures include "surgical exploration". Procedures of this kind come with a significant amount of risk, carrying up to a 17.4% predicted mortality rate. This is especially concerning for our target population of pediatric patients with congenital abnormalities of the heart and major pulmonary vessels. This paper offers a novel approach to surgical planning which includes studying virtual and physical models of pulmonary vasculature of an individual patient before operation obtained from conventional 3D X-ray computed tomography (CT) scans of the chest. These models would provide clinicians with a non-invasive, intricately detailed representation of patient anatomy, and could reduce the need for invasive planning procedures such as exploratory surgery. Researchers involved in the AirPROM project have already demonstrated the utility of virtual and physical models in treatment planning of the airways of the chest. Clinicians have acknowledged the potential benefit from such a technology. A method for creating patient-derived physical models is demonstrated on pulmonary vasculature extracted from a CT scan with contrast of an adult human. Using a modified version of the NIH ImageJ program, a series of image processing functions are used to extract and mathematically reconstruct the vasculature tree structures of interest. An auto-generated STL file is sent to a 3D printer to create a physical model of the major pulmonary vasculature generated from 3D CT scans of patients.

    There are contradictory results regarding a potential increased responsiveness of younger women with high-risk primary breast cancer to high-dose compared with standard-dose chemotherapy. Observations from some, but not all, randomized trials, suggest that the potential benefit of high-dose treatment may be limited to younger patients. We analyzed, at median follow-up of 8 years, the prognostic effect of age in 264 patients enrolled in prospective phase II and III trials of high-dose chemotherapy, using a uniform regimen. Median age was 49 (range, 36-71). Among patients < or = 49 and > 49 years of age, the relapse rates were 27% and 25%, respectively (P = 0.7). In those age groups, the transplant-related mortality rates were 6.5% and 4%, respectively (P = 0.8). No age differences were observed between patients surviving transplant (median age 49) and those who experienced transplant-related mortality (median 47.5) (P = 0.9). Event-free survival (P = 0.3) and overall survival (P = 0.4) did not differ between patients < or = 49 and > 49 years of age. In conclusion, we did not detect a detrimental effect of older age on transplant-related mortality or relapse after high-dose chemotherapy for high-risk primary breast cancer at long-term follow-up. The debate about the age effect in this population remains unsettled. PMID:15923796

    The prevalence of a high risk exercise (Ex) Tl-201 (Tl) scintigram (scint) was determined in 295 consecutive patients (pts) with angiographic (angio) (>50% stenosis) coronary artery disease (CAD) and correlated with extent of CAD and Ex stress test findings. A high risk scint by quantitative criteria was defined as either: 1) a typical left main (LM) CAD pattern showing greater than or equal to 25% homogenous disease in Tl activity in septal and posterolateral walls; 2) a multivessel disease (MVD) pattern showing abnormal Tl uptake and/or washout in multiple vascular scan segments; 3) increased lung Tl uptake. The typical LMCAD pattern was observed in 6 of 43 pts (14%) with LMCAD compared to 2% of 53 pts with 3VD (p=0.03), 3% of 99 pts with 2VD (p=0.02) and 2% of 100 pts with 1VD (p-0.01). The MVD scint pattern was seen in 67% of pts with LMCAD compared to 49% (p=0.05) in 3VD pts, 41% (p=0.004) in 2VD pts and 24% (p=<0.0001) in 1VD pts. Prevalence of abnormal lung Tl was comparable in LMCAD (42%), 3VD (38%) and 2VD (34%) pts, but greater than observed in 1VD pts (26%; p=0.05). High risk ECG stress test was defined as 2 or more of: 1) >2.0 mm of ST decreasing; 2) greater than or equal to1.0 mm ST decreasing persisting >5 min post-EX; 3) ST decreasing at less than or equal to5 METS; 4) greater than or equal to10 mm Hg decreasing in Ex blood pressure. A high risk ECG stress test was observed in 58% of LMCAD pts compared to 32% of 3VD pts (p=0.009), 31% of 2VD pts (p=0.003) and 16% of 1VD pts (p<0.0001). Eighty-six % of LMCAD and 70% of 2 and 3VD pts had either a high risk Ex scint or stress test. Thus, EX Tl-201 scint appears useful in identifying high risk CAD pts.

    Negative pressure pulmonary edema is a potentially life-threatening condition that may occur when a large negative intrathoracic pressure is generated against a 'physically' obstructed upper airway during emergence from anesthesia. We report a 35 year old male patient who is morbidly obese and undergoing laparoscopic gastric bypass who developed negative pressure pulmonary edema without any evidence of a 'physical' upper airway obstruction. In our patient, the negative pressure pulmonary edema occurred after complete reversal of neuromuscular blockade and during manual positive pressure ventilation with the endotracheal tube still in place and in the presence of an oral airway. Since the patient was still intubated and had an airway in place with no possibility for physical obstruction, we speculate that the occurrence of the negative pressure pulmonary edema was mainly due to a 'functional' obstruction secondary to the severe patient-ventilation asynchrony that ensued upon reversal of the neuromuscular blockade.

    The purpose of this study was to evaluate the efficacy of negative pressure wound therapy (NPWT) compared with standard of care on wound healing in high-risk patients with multiple significant comorbidities and chronic lower extremity ulcers (LEUs) across the continuum of care settings. A retrospective cohort study of 'real-world' high-risk patients was conducted using Boston University Medical Center electronic medical records, along with chart abstraction to capture detailed medical history, comorbidities, healing outcomes and ulcer characteristics. A total of 342 patients, 171 NPWT patients with LEUs were matched with 171 non-NPWT patients with respect to age and gender, were included in this cohort from 2002 to 2010. The hazard ratios (HRs) were estimated by COX proportional hazard models after adjusting for potential confounders. The NPWT patients were 2·63 times (95% CI = 1·87-3·70) more likely to achieve wound closure compared with non-NPWT patients. Moreover, incidence of wound closure in NPWT patients were increased in diabetic ulcers (HR = 3·26, 95% CI = 2·21-4·83), arterial ulcers (HR = 2·27, CI = 1·56-3·78) and venous ulcers (HR = 6·31, 95% CI = 1·49-26·6) compared with non-NPWT patients. In addition, wound healing appeared to be positively affected by the timing of NPWT application. Compared with later NPWT users (1 year or later after ulcer onset), early NPWT users (within 3 months after ulcer onset) and intermediate NPWT users (4-12 months after ulcer onset) were 3·38 and 2·18 times more likely to achieve wound healing, respectively. This study showed that despite the greater significant comorbidities, patients receiving NPWT healed faster. Early use of NPWT demonstrated better healing. The longer the interval before intervention is with NPWT, the higher the correlation is with poor outcome. PMID:23163962

    Objectives To determine whether a less invasive approach to aortic valve replacement (AVR) improves clinical outcomes in diabetic patients with aortic stenosis (AS). Background Diabetes is associated with increased morbidity and mortality after surgical AVR for AS. Methods Among treated patients with severe symptomatic AS at high-risk for surgery in the PARTNER trial, we examined outcomes stratified by diabetes status of patients randomly assigned to transcatheter or surgical AVR. The primary outcome was all-cause mortality at 1 year. Results Among 657 patients enrolled in PARTNER who underwent treatment, there were 275 patients with diabetes (145 transcatheter, 130 surgical). There was a significant interaction between diabetes and treatment group for 1-year all-cause mortality (p=0.048). Among diabetic patients, all-cause mortality at 1 year was 18.0% in the transcatheter group and 27.4% in the surgical group (HR 0.60; 95% CI, 0.36–0.99; p=0.04). Results were consistent among patients treated via transfemoral or transapical routes. In contrast, among non-diabetic patients, there was no significant difference in all-cause mortality at 1 year (p=0.48). Among diabetic patients, the 1-year rates of stroke were similar between treatment groups (3.5% transcatheter vs. 3.5% surgery, p=0.88), but the rates of renal failure requiring dialysis >30 days were lower in the transcatheter group (0% vs. 6.1%, p=0.003). Conclusions Among patients with diabetes and severe symptomatic AS at high-risk for surgery, this post-hoc stratified analysis of the PARTNER trial suggests there is a survival benefit, no increase in stroke, and less renal failure from treatment with transcatheter compared to surgical AVR.

    Background Peanut allergy is a major public health problem that affects 1% of the population and has no effective therapy. Objective To examine the safety and efficacy of oraldesensitization in peanut allergic children in combination with a brief course of anti-IgE monoclonal antibody (omalizumab, Xolair). Methods We performed oral peanut desensitization in peanut allergic children at high risk for developing significant peanut-induced allergic reactions. Omalizumab was administered prior to and during oral peanut desensitization. Results We enrolled 13 children (median age, 10 years), with a median peanut-specific IgE of 229 kUA/L and a median total serum IgE of 621 kU/L, who failed an initial double-blind placebo controlled food challenge at doses 100 mg peanut flour. After pre-treatment with omalizumab, all subjects tolerated the initial 11 desensitization doses given on the first day, including the maximum dose of 500 mg peanut flour (cumulative dose, 992 mg, equivalent to >2 peanuts), requiring minimal or no rescue therapy. 12 subjects then reached the maximum maintenance dose of 4,000 mg peanut flour/day in a median time of 8 weeks, at which point omalizumab was discontinued. All 12 subjects continued on 4,000 mg peanut flour/day and subsequently tolerated a challenge with 8,000 mg peanut flour (equivalent to about 20 peanuts), or 160 to 400 times the dose tolerated before desensitization. During the study, 6 of the 13 subjects experienced mild or no allergic reactions; 6 subjects had Grade 2, and 2 subjects Grade 3 reactions, all of which responded rapidly to treatment. Conclusions Among children with high-risk peanut allergy, treatment with omalizumab may facilitate rapid oral desensitization, and qualitativelyimprove the desensitization process. PMID:24176117

    Context: Combined spinal epidural anesthesia (CSEA) has a significant advantage by enabling the use of low dose intrathecal local anesthetic, with knowledge that the epidural catheter may be used to extend the block as necessary. CSEA is useful in high-risk geriatric patients by providing greater hemodynamic stability. Aim: This study is designed to compare the clinical effects of CSEA versus spinal anesthesia in high-risk geriatric patients undergoing surgeries around the hip joint. Materials and Methods: Sixty patients aged >65 years, American Society of Anaesthesiology III and IV were randomly allocated into two equal groups. Group A (n = 30) received CSEA with 1 ml (5 mg) of 0.5% hyperbaric bupivacaine with 25 μg fentanyl through spinal route, and the expected incompleteness of spinal block was managed with small incremental dose of 0.5% isobaric bupivacaine through epidural catheter, 1–1.5 ml for every unblocked segment to achieve T10 sensory level. Group B (n = 30) received spinal anesthesia with 2.5 ml (12.5 mg) of 0.5% hyperbaric bupivacaine and 25 μg fentanyl. Result: Both the groups showed rapid onset, excellent analgesia and good quality motor block. Group A showed a significantly less incidence of hypotension (P < 0.01) along with the provision of prolonging analgesia as compared to Group B. Conclusion: CSEA is a safe, effective, reliable technique with better hemodynamic stability along with the provision of prolonging analgesia compared to spinal anesthesia for high-risk geriatric patients undergoing surgeries around the hip joint.

    Purpose The aim of the current study is to assess the spectrum of genetic variation in the BRIP1 gene among Korean high-risk breast cancer patients who tested negative for the BRCA1/2 mutation. Materials and Methods Overall, 235 Korean patientswith BRCA1/2 mutation–negative high-risk breast cancerwere screened for BRIP1 mutations. The entire BRIP1 gene was analyzed using fluorescent-conformation sensitive gel electrophoresis. In silico analysis of BRIP1 variants was performed using PolyPhen-2 and SIFT. Results A total of 20 sequence alterations including 12 exonic and eight intronic variantswere found. Among the 12 exonic variants, 10 were missense and two were silent mutations. No protein-truncating mutation was found among the tested patients. Among the 10 missense variants, four (p.L263F, p.L340F, p.L474P, and p.R848H) were predicted to be pathogenic by both PolyPhen-2 and SIFT, and these variants were found in five patients. Of the four missense variants, p.L263F, p.L474P, and p.R848H localize to regions between the helicase motifs, while p.L340F resides in an iron-sulfur domain of BRIP1. Conclusion No protein-truncating mutation in BRIP1 was found among the tested patients. The contribution of BRIP1 variants is thought to be minor in Korean non-BRCA1/2 high-risk breast cancer.

    Background Postoperative nausea and vomiting (PONV) continues to be a major problem, because PONV is associated with delayed recovery and prolonged hospital stay. Although the PONV guidelines recommended the use of 5-hydroxy-tryptamine (5-HT3) receptor antagonists as the first-line prophylactic agents in patients categorized as high-risk, there are few studies comparing the efficacies of ondansetron, ramosetron, and palonosetron. The aim of present study was to compare the prophylactic antiemetic efficacies of three 5HT3 receptor antagonists in high-risk patients after laparoscopic surgery. Methods In this prospective, randomized, double-blinded trial, 109 female nonsmokers scheduled for elective laparoscopic surgery were randomized to receive intravenous 4 mg ondansetron (n = 35), 0.3 mg ramosetron (n = 38), or 75 µg palonosetron (n = 36) before anesthesia. Fentanyl-based intravenous patient-controlled analgesia was administered for 48 h after surgery. Primary antiemetic efficacy variables were the incidence and severity of nausea, the frequency of emetic episodes during the first 48 h after surgery, and the need to use a rescue antiemetic medication. Results The overall incidence of nausea/retching/vomiting was lower in the palonosetron (22.2%/11.1%/5.6%) than in the ondansetron (77.1%/48.6%/28.6%) and ramosetron (60.5%/28.9%/18.4%) groups. The rescue antiemetic therapy was required less frequently in the palonosetron group than the other groups (P < 0.001). Kaplan-Meier analysis showed that the order of prophylactic efficacy in delaying the interval to use of a rescue emetic was palonosetron, ramosetron, and ondansetron. Conclusions Single-dose palonosetron is the prophylactic antiemetics of choice in high-risk patients undergoing laparoscopic surgery. PMID:23814652

    Patients with localized high-risk soft tissue sarcomas (STS) of the limbs and trunk wall still have a considerable metastatic recurrence rate of more than 50%, in spite of adjuvant chemotherapy. This drug-ceiling effect of chemotherapy in sarcoma setting could be explained, at least partially, by multidrug resistance (MDR) mechanisms. The aim of this study was to ascertain whether mRNA and protein expression of ABCB1 (P-glycoprotein), ABCC1 (MRP1), and GSTA1 (glutathione S-transferase pi) was prognostic in localized high-risk STS. Immunohistochemistry and reverse transcriptase-PCR studies were performed from biopsies at the time of diagnosis. Patients of this series were prospectively enrolled into a phase III trial that compared three versus five cycles of epirubicin plus ifosfamide. The series of 102 patients found 41 events of recurrence and 37 of death with a median follow-up of 68 months. In univariate analysis, variables with a statistically significant relationship with relapse-free survival (RFS) were: MRP1 expression (5-year RFS rate of 23% in positive cases and 63% in negative cases, P = 0.029), histology (5-year RFS rate of 74% in undifferentiated pleomorphic sarcoma and 43% in synovial sarcoma, P = 0.028), and ABCC1 expression (5-year RFS rate of 33% in overexpression and 65% in downregulation, P = 0.012). Combined ABCC1/MRP1 was the only independent prognostic factor for both RFS (HR = 2.704, P = 0.005) and overall survival (HR = 2.208, P = 0.029). ABCC1/MRP1 expression shows robust prognostic relevance in patients with localized high-risk STS treated with anthracycline-based chemotherapy, which is the standard front line treatment in STS. This finding deserves attention as it points to a new targetable protein in STS. PMID:24145283

    Pregnant women with triple antibody positive antiphospholipid syndrome (APS) who have had thrombosis or a history of early, severe pregnancy complications are generally considered at high risk of pregnancy loss. The objectives of this study were to investigate the efficacy and safety of a relatively new treatment protocol used in addition to conventional therapy in high-risk pregnant patients affected with primary APS. The study's two inclusion criteria were: (1) the presence of triple antiphospholipid positivity, (2) previous thrombosis and/or a history of one or more early, severe pregnancy complications. Eighteen pregnancies occurring between 2002 and 2015 in 14 APS patients, (mean age 34.8±3.6 SD) were monitored. All 14 (100%) patients had triple antiphospholipid positivity. In addition, six of them (42.8%) had a history of thrombosis, four (28.6%) had one or more previous early and severe pregnancy complications, and four (30.8%) met both clinical study criteria. The study protocol included weekly plasmapheresis or immunoadsorption and fortnightly 1g/kg intravenous immunoglobulins. Seventeen of the pregnancies (94.4%) produced live neonates, all born between the 26th and 37th weeks of gestation (mean 33.1±3.5 SD). One female (5.5%), born prematurely at 24 weeks, died of sepsis a week after birth. There were two cases (11.1%) of severe pregnancy complications. No treatment side effects were registered. Given the high live birth rate and the safety associated to it, the study protocol described here could be taken into consideration by medical teams treating high-risk APS pregnant patients.

    Purpose: Radiation therapy remains an essential treatment for patients with parameningeal rhabdomyosarcoma (PMRMS), and early radiation therapy may improve local control for patients with intracranial extension (ICE). Methods and Materials: To address the role of radiation therapy timing in PMRMS in the current era, we reviewed the outcome from 2 recent clinical trials for intermediate-risk RMS: Intergroup Rhabdomyosarcoma Study (IRS)-IV and Children's Oncology Group (COG) D9803. The PMRMS patients on IRS-IV with any high-risk features (cranial nerve palsy [CNP], cranial base bony erosion [CBBE], or ICE) were treated immediately at day 0, and PMRMS patients without any of these 3 features received week 6-9 radiation therapy. The D9803 PMRMS patients with ICE received day 0 X-Ray Therapy (XRT) as well; however, those with either CNP or CBBE had XRT at week 12. Results: Compared with the 198 PMRMS patients from IRS-IV, the 192 PMRMS patients from D9803 had no difference (P<.05) in 5-year local failure (19% vs 19%), failure-free-survival (70% vs 67%), or overall survival (75% vs 73%) in aggregate. The 5-year local failure rates by subset did not differ when patients were classified as having no risk features (None, 15% vs 19%, P=.25), cranial nerve palsy/cranial base of skull erosion (CNP/CBBE, 15% vs 28%, P=.22), or intracranial extension (ICE, 21% vs 15%, P=.27). The D9083 patients were more likely to have received initial staging by magnetic resonance imaging (71% vs 53%). Conclusions: These data support that a delay in radiation therapy for high-risk PMRMS features of CNP/CBBE does not compromise clinical outcomes.

  19. The use of the Airtraq® optical laryngoscope for routine tracheal intubation in high-risk cardio-surgical patients

    2011-01-01

    Background The Airtraq® optical laryngoscope (Prodol Ltd., Vizcaya, Spain) is a novel disposable device facilitating tracheal intubation in routine and difficult airway patients. No data investigating routine tracheal intubation using the Airtaq® in patients at a high cardiac risk are available at present. Purpose of this study was to investigate the feasibility and hemodynamic implications of tracheal intubation with the Aitraq® optical laryngoscope, in high-risk cardio-surgical patients. Methods 123 consecutive ASA III patients undergoing elective coronary artery bypass grafting were routinely intubated with the Airtraq® laryngoscope. Induction of anesthesia was standardized according to our institutional protocol. All tracheal intubations were performed by six anesthetists trained in the use of the Airtraq® prior. Results Overall success rate was 100% (n = 123). All but five patients trachea could be intubated in the first attempt (95,9%). 5 patients were intubated in a 2nd (n = 4) or 3rd (n = 1) attempt. Mean intubation time was 24.3 s (range 16-128 s). Heart rate, arterial blood pressure and SpO2 were not significantly altered. Minor complications were observed in 6 patients (4,8%), i.e. two lesions of the lips and four minor superficial mucosal bleedings. Intubation duration (p = 0.62) and number of attempts (p = 0.26) were independent from BMI and Mallampati score. Conclusion Tracheal intubation with the Airtraq® optical laryngoscope was feasible, save and easy to perform in high-risk patients undergoing cardiac surgery. In all patients, a sufficient view on the vocal cords could be obtained, independent from BMI and preoperative Mallampati score. Trial Registration DRKS 00003230 PMID:22011403

    The aim of the study was to report the clinical results in patients with high-risk prostate cancer treated with pelvic intensity-modulated radiation therapy (IMRT) and simultaneous integrated boost (SIB) to the prostate area. A total of 110 patients entered our study, 37 patients presented with localized prostate cancer and radiological evidence of node metastases or ≥15% estimated risk of lymph node (LN) involvement, while 73 patients underwent postoperative adjuvant or salvage irradiation for biochemical or residual/recurrent disease, LN metastases, or high risk of harboring nodal metastases. All patients received androgen deprivation therapy (ADT) for 2 years. The median follow-up was 56.5 months. For the whole patient group, the 3- and 5-year freedom from biochemical failure were 82.6% and 74.6%, respectively, with a better outcome in patients treated with radical approach. The 3- and 5-year freedom from local failure were 94.4% and 90.2%, respectively, while the 3- and 5-year distant metastasis-free survival were 87.8% and 81.7%, respectively. For all study patients, the rate of freedom from G2 acute rectal, intestinal, and urinary toxicities was 60%, 77%, and 61%, respectively. There was no G3 acute toxicity, ≥G2 late intestinal toxicity, or G3 late urinary or rectal toxicity. The 3- and 5-year ≥G2 freedom from late rectal toxicity rate were 98% and 95%, respectively, while the 3- and 5-year ≥G2 freedom from late urinary toxicity rate were 95% and 88%, respectively. The study concludes that pelvic IMRT and SIB to the prostatic area in association with 2-year ADT was a well-tolerated technique, providing high disease control in patients with prostate cancer requiring LN treatment.

    Birt-Hogg-Dubé syndrome (BHD) is an inherited disorder caused by genetic mutations in the folliculin (FLCN) gene. Individuals with BHD have multiple pulmonary cysts and are at a high risk for developing renal cell carcinomas (RCCs). Currently, little information is available about whether pulmonary cysts are absolutely benign or if the lungs are at an increased risk for developing neoplasms. Herein, we describe 14 pulmonary neoplastic lesions in 7 patients with BHD. All patients were confirmed to have germline FLCN mutations. Neoplasm histologies included adenocarcinoma in situ (n = 2), minimally invasive adenocarcinoma (n = 1), papillary adenocarcinoma (n = 1), micropapillary adenocarcinoma (n = 1), atypical adenomatous hyperplasia (n = 8), and micronodular pneumocyte hyperplasia (MPH)-like lesion (n = 1). Five of the six adenocarcinoma/MPH-like lesions (83.3%) demonstrated a loss of heterozygosity (LOH) of FLCN. All of these lesions lacked mutant alleles and preserved wild-type alleles. Three invasive adenocarcinomas possessed additional somatic events: 2 had a somatic mutation in the epidermal growth factor receptor gene (EGFR) and another had a somatic mutation in KRAS. Immunohistochemical analysis revealed that most of the lesions were immunostained for phospho-mammalian target of rapamycin (p-mTOR) and phospho-S6. Collective data indicated that pulmonary neoplasms of peripheral adenocarcinomatous lineage in BHD patients frequently exhibit LOH of FLCN with mTOR pathway signaling. Additional driver gene mutations were detected only in invasive cases, suggesting that FLCN LOH may be an underlying abnormality that cooperates with major driver gene mutations in the progression of pulmonary adenocarcinomas in BHD patients.

    The ischemia necrosis of limb frequently requires surgery of amputation. Lumbar plexus and sciatic nerve block is an ideal intra-operative anesthetic and post-operative antalgic technique for patients of amputation, especially for high-risk patients who have severe cardio-cerebrovascular diseases. However, the duration of analgesia of peripheral nerve block is hardly sufficient to avoid the postoperative pain and the usage of opioids. In this case, a 79-year-old man, with multiple cerebral infarcts, congestive heart failure, atrial flutter and syncope, was treated with an above knee amputation because of ischemia necrosis of his left lower limb. Dexmedetomidine 1 μg/kg was added to 0.33% ropivacaine for lumbar plexus and sciatic nerve block in this case for intra-operative anesthesia and post-operative analgesia. The sensory function was blocked fully for surgery and the duration of analgesia maintained 26 hours with haemodynamic stability and moderate sedation. The patient did not complain pain and require any supplementary analgesics after surgery. This case showed that adding 1 μg/kg dexmedetomidine to ropivacaine for lumbar plexus and sciatic nerve block may be a feasible and safe technique for high-risk patients for lower limb surgery of amputation.

    This is the first study to investigate the vasculoangiogenic effects of cilostazol on endothelial progenitor cells (EPCs) and flow-mediated dilatation (FMD) in patients at high risk of cardiovascular disease (CVD). This double-blind, placebo-controlled study included 71 patients (37 received 200 mg/d cilostazol and 34 received placebo for 12 weeks). Use of cilostazol, but not placebo, significantly increased circulating EPC (kinase insert domain receptor(+)CD34(+)) counts (percentage changes: 149.0% [67.9%-497.8%] vs 71.9% [-31.8% to 236.5%], P = .024) and improved triglyceride and high-density lipoprotein cholesterol levels (P = .002 and P = .003, respectively). Plasma levels of vascular endothelial growth factor (VEGF)-A165 and FMD significantly increased (72.5% [32.9%-120.4%] vs -5.8% [-46.0% to 57.6%], P = .001; 232.8% ± 83.1% vs -46.9% ± 21.5%, P = .003, respectively) in cilostazol-treated patients. Changes in the plasma triglyceride levels significantly inversely correlated with the changes in the VEGF-A165 levels and FMD. Cilostazol significantly enhanced the mobilization of EPCs and improved endothelium-dependent function by modifying some metabolic and angiogenic markers in patients at high risk of CVD.

    High-risk neuroblastoma is characterised by poor long-term survival, especially for very high-risk (VHR) patients (poor response of metastases after induction therapy). We report the results of an intensified high-dose chemotherapy (HDC) strategy to improve the prognosis of VHR patients. This strategy was based on tandem HDC with thiotepa and busulfan-melphalan (Bu-Mel) followed by autologous stem cell transplantation (ASCT). All data were prospectively recorded in the Gustave Roussy Paediatric ASCT database. From April 2004 to August 2011, 26 patients were eligible for tandem HDC. The median age at diagnosis was 4.4 years (1-15.9). All patients had metastatic disease. MYCN was amplified in 5/26 tumours. Despite the cumulative toxicity of alkylating agents, the toxicity of the intensified HDC strategy was manageable. Thiotepa-related toxicity was mainly digestive, whereas sinusoidal obstruction syndrome was the main toxicity observed after Bu-Mel. The 3-year event-free survival of this cohort was 37.3% (21.3-56.7). This strategy will be compared with combined (131)I-mIBG/Bu-Mel in the upcoming SIOPEN VHR Neuroblastoma Protocol. PMID:26524264

    Objective The rs1333049, rs10757278 and rs4977574 are single nucleotide polymorphisms (SNPs) of chromosome 9p21 locus that are associated with prevalence of acute coronary syndromes (ACS). The rs1333049 SNP was also associated with cardiac outcome 6 months post ACS. No data concerning their association with long term prognosis after myocardial infarction is available. The aim of our study was to investigate the association of the 9p21.3 locus with 5-year overall mortality in patients with ST-elevation myocardial infarction (STEMI) treated invasively. Materials and Methods We performed a retrospective analysis of data collected prospectively in a registry of consecutive patients with STEMI treated with primary PCI. Genotyping was performed with a TaqMan method. The analyzed end-point was total 5-year mortality. Results The study group comprised 589 patients: 25.3% of females (n = 149), mean age 62.4±11.9 years, total 5-year mortality 16.6% (n = 98). When all the study group was analyzed, no significant differences in mortality were found between the genotypes. However, in high-risk patients (Grace risk score ≥155 points, n = 238), low-risk homozygotes had significantly better 5-year survival compared to other genotypes. The hazard ratio associated with high-risk genotype (high-risk homozygote or heterozygote) was: HR = 2.9 (95%CI 1.4–6.1) for the rs4977574 polymorphism, HR = 2.6 (1.25–5.3) for the rs1333049 one and HR = 2.35 (1.2–4.6) for the rs10757278 one (Cox proportional hazards model). Conclusions The 9p21.3 locus is associated with 5-year mortality in high-risk patients with STEMI. This finding, due to very high effect size, could potentially be applied into clinical practice, if appropriate methods are elaborated. PMID:24069144

    Objective The rs10757278, rs1333049 and rs4977574 are single nucleotide polymorphisms (SNPs) of chromosome 9p21 locus associated with a prevalence of acute coronary syndromes (ACS). Reports concerning their association with long-term outcome after an ACS are equivocal. The aim of our study was to investigate the association of the 9p21.3 locus with 5-year overall mortality in patients with ST-elevation myocardial infarction (STEMI). Materials and methods We performed a retrospective analysis of data collected prospectively in 2 independent registries of consecutive patients with STEMI (derivation and validation group). Genotyping was performed with the TaqMan method. The analyzed end-point was total mortality. Results The derivation group comprised 589 patients: 25.3% female (n = 149), mean age 62.4±12.0 years, total 5-year mortality 16.6% (n = 98). When all the study group was analyzed, no significant differences in mortality were found between the genotypes. However, in high-risk patients (GRACE risk score ≥155 points, n = 238), homozygotes associated with higher risk for ACS had significantly better 5-year survival compared to other genotypes. The hazard ratio associated with the high-risk genotype (a homozygote of high risk for ACS or a heterozygote) was: HR = 2.2 (1.15–4.2) for the rs10757278 polymorphism, HR = 2.7 (95% CI 1.3–5.4) for the rs4977574 one and HR = 2.3 (1.2–4.5) for the rs1333049 one (Cox proportional hazards model). Survival analysis in the validation group (n = 365) showed a clear trend towards better prognosis in GG homozygotes of the rs10757278 SNP, which confirms our initial results (p = 0.09, log-rank test). Conclusions The 9p21.3 locus is associated with 5-year mortality in high-risk patients with STEMI. The genotypes associated with higher risk for ACS show a protective effect in terms of further survival (instead of a deteriorating prognosis, as reported previously). This finding, due to the very

    Aims In the Digitalis Investigation Group (DIG) trial, digoxin reduced mortality or hospitalization due to heart failure (HF) in several pre-specified high-risk subgroups of HF patients, but data on protocol-specified 2-year outcomes were not presented. In the current study, we examined the effect of digoxin on HF death or HF hospitalization and all-cause death or all-cause hospitalization in high-risk subgroups during the protocol-specified 2 years of post-randomization follow-up. Methods and results In the DIG trial, 6800 ambulatory patients with chronic HF, normal sinus rhythm, and LVEF ≤45% (mean age 64 years, 26% women, 17% non-whites) were randomized to receive digoxin or placebo. The three high-risk groups were defined as NYHA class III–IV symptoms (n = 2223), LVEF <25% (n = 2256), and cardiothoracic ratio (CTR) >55% (n = 2345). In all three high-risk subgroups, compared with patients in the placebo group, those in the digoxin group had a significant reduction in the risk of the 2-year composite endpoint of HF mortality or HF hospitalization: NYHA III–IV [hazard ratio (HR) 0.65; 95% confidence interval (CI) 0.57–0.75; P < 0.001], LVEF <25% (HR 0.61; 95% CI 0.53–0.71; P < 0.001), and CTR >55% (HR 0.65; 95% CI 0.57–0.75; P < 0.001). Digoxin-associated HRs (95% CI) for 2-year all-cause mortality or all-cause hospitalization for subgroups with NYHA III–IV, LVEF <25%, and CTR >55% were 0.88 (0.80–0.97; P = 0.012), 0.84 (0.76–0.93; P = 0.001), and 0.85 (0.77–0.94; P = 0.002), respectively. Conclusions Digoxin improves outcomes in chronic HF patients with NYHA class III–IV, LVEF <25%, or CTR >55%, and should be considered in these patients. PMID:23355060

    Background Early identification and treatment of chronic thromboembolic pulmonary hypertension (CTEPH) are critical to prevent disease progression. We determined the incidence and risk factors for CTEPH in patients with a first episode of acute pulmonary embolism (PE). Methods In this study, consecutive patients with first-episode acute PE were followed for ≤5 years. Pulmonary hypertension (PH) was screened for by echocardiography. Suspected cases were evaluated by right heart catheterization (RHC) and pulmonary angiography (PA). If invasive procedures were not permitted, PH was diagnosed by systolic pulmonary artery pressure (SPAP) >50 mmHg. Diagnosis of CTEPH was confirmed by PA, ventilation/perfusion (V/Q) lung scan, or computed tomography (CT) PA (CTPA). Results Overall, 614 patients with acute PE were included (median follow-up, 3.3 years). Ten patients were diagnosed with CTEPH: cumulative incidence 0.8% [95% confidence interval (CI), 0.0-1.6%] at 1 year, 1.3% (95% CI, 0.3-2.3%) at 2 years, and 1.7% (95% CI, 0.7-2.7%) at 3 years. No cases of CTEPH developed after 3 years. History of lower-limb varicose veins [hazard ratio (HR), 4.3; 95% CI, 1.2-15.4; P=0.024], SPAP >50 mmHg at initial PE episode (HR, 23.5; 95% CI, 2.7-207.6; P=0.005), intermediate-risk PE (HR, 1.2; 95% CI, 1.0-1.4; P=0.030), and CT obstruction index over 30% at 3 months after acute PE (HR, 42.5; 95% CI, 4.4-409.8; P=0.001) were associated with increased risk of CTEPH. Conclusions CTEPH was not rare after acute PE in this Chinese population, especially within 3 years of diagnosis. Lower-limb varicose veins, intermediate-risk PE with elevated SPAP in the acute phase, and residual emboli during follow-up might increase the risk of CTEPH. PMID:26716031

    Abstract To evaluate the efficacy of percutaneous transhepatic gallbladder drainage (PTGD) for high-risk elderly patients with acute cholecystitis. Retrospective analysis of 159 acute cholecystitis patients who were admitted to General Surgery Division III of the First Affiliated Hospital of Dalian Medical University between January 2005 and November 2012. A total of 123 patients underwent laparoscopic cholecystectomy (LC), and 36 received only PTGD treatment. The LC patients were divided into 3 groups based on their preoperative treatment: group A, emergency patients (33 patients); group B (26 patients), patients who were treated with PTGD prior to LC; and group C (64 patients), patients who received nonsurgical treatment prior to LC. General conditions, LC surgery duration, intraoperative blood loss, rate of conversion to open surgery, incidence of postoperative complications, total fasting time, and total hospitalization time were analyzed and compared among the 3 groups. The remission rates of patients in the PTGD treatment groups (including group B and PTGD treatment only group) were significantly higher within 24 and 48 hours than those of patients who received nonsurgical treatment prior to LC (P < 0.05). Among the patients in the 3 surgery groups, the operation conversion rate (19.2%) of group B was significantly higher than that of group A (3.0%) and group C (1.6%) (P < 0.05). The total hospitalization time of the patients in group B (18.5 ± 4.5 days) was longer than that of the patients in group A (8.2 ± 3.9 days) and group C (10.5 ± 6.4 days). The total fasting time of the patients in group A (2.4 ± 1.2 days) was significantly shorter than that of those in group B (4.1 ± 1.7 days) and group C (3.4 ± 2.7 days) (P < 0.05).

    Delivery of anesthesia to patients with severe pulmonary hypertension can be extremely challenging. The profound hemodynamic alterations of the disease can often be exacerbated by alterations in circulatory function brought about by anesthetic and surgical interventions. High perioperative morbidity and mortality rates have been reported. Minimizing adverse outcomes in these patients requires careful perioperative evaluation and planning. Selection of an anesthetic technique suitable for the surgery without causing major hemodynamic alterations, which can lead to cardiac failure and death, is a unique consideration of the anesthesia provider. As shown in this case report, caudal anesthesia, when appropriate, can offer a safe anesthetic for these patients. PMID:20572406

    The aim of this study was to give an in-depth consideration of the chronic obstructive pulmonary disease (COPD) patients' subjective view of the impact of pulmonary rehabilitation (PR) on their lives. A systematic review in PubMed, Embase, CINAHL and PsychInfo databases yielded 3306 articles, of which 387 were duplicates, 263 remained after screening abstract and title; of them, 4 were excluded (editorial or due to lacking of full text) remaining a total of 259 for full text reading. Among these, eight studies met the inclusion criteria and were finally included. The meta-ethnography approach synthesized an understanding of the studies, which focused on constructing interpretations and developed a 'line-of-argument' synthesis. The psychosocial support of PR contributes to the patients' strength and desire for participation and the health education leads to illness-perception learning. Both psychosocial support and health education develop patients' empowerment, while PR promotes opportunities to health transitions. The empowerment experienced by the patients in taking advantage of these opportunities leads to positive impacts over time. If they do not exploit these occasions, negative impacts arise in their life, which make the treatment assistance or follow-up more difficult. The COPD patients' feedback revealed that PR promotes a better 'way of life', well-being and important behavioural changes towards health promotion. PMID:23897930

    Detecting an improvement of lung function in a patient with chronic obstructive pulmonary disease (COPD) following pulmonary rehabilitation (PR) may appear unexpected, but actually recent studies showed that is not so rare. In fact, in a prospective study comparing a group of 190 COPD patients undergoing PR to a group of 67 patients treated only with drugs a mean improvement of FEV1 from 1240 mL to 1252.4 mL was found in the former, while the values changed from 1367 mL to 1150 mL in the latter (p < 0.001). Such improvement was detected also in a study in patients with very severe COPD, as assessed by a FEV1 increasing from 970 mL at baseline to 1080 mL after a 3-week PR inpatient program (p < 0.001). These observations suggest that improvement of lung function in COPD patients undergoing PR should be included among the expected outcomes and routinely assessed as an index of clinical success during the treatment.

    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

    Background. The STOP-BANG questionnaire has been used to identify surgical patients at risk for undiagnosed obstructive sleep apnea (OSA) by classifying patients as low risk (LR) if STOP-BANG score < 3 or high risk (HR) if STOP-BANG score ≥ 3. Few studies have examined whether postoperative complications are increased in HR patients and none have been described in oncologic patients. Objective. This retrospective study examined if HR patients experience increased complications evidenced by an increased length of stay (LOS) in the postanesthesia care unit (PACU). Methods. We retrospectively measured LOS and the frequency of oxygen desaturation (<93%) in cancer patients who were given the STOP-BANG questionnaire prior to cystoscopy for urologic disease in an ambulatory surgery center. Results. The majority of patients in our study were men (77.7%), over the age of 50 (90.1%), and had BMI < 30 kg/m2 (88.4%). STOP-BANG results were obtained on 404 patients. Cumulative incidence of the time to discharge between HR and the LR groups was plotted. By 8 hours, LR patients showed a higher cumulative probability of being discharged early (80% versus 74%, P = 0.008). Conclusions. Urologic oncology patients at HR for OSA based on the STOP-BANG questionnaire were less likely to be discharged early from the PACU compared to LR patients. PMID:27610133

    Background The clinical benefits of postoperative radiation therapy (PORT) for patients with thymoma are still controversial. In the absence of defined guidelines, prognostic factors such as stage, status of surgical margins, and histology are often considered to guide the choice of adjuvant treatment (radiotherapy and/or chemotherapy). In this study, we describe our single-institution experience of three-dimensional conformal PORT administered as adjuvant treatment to patients with thymoma. Methods Twenty-two consecutive thymoma patients (eleven male and eleven female) with a median age of 52 years and treated at our institution by PORT were analyzed. The patients were considered at high risk of recurrence, having at least one of the following features: stage IIB or III, involved resection margins, or thymic carcinoma histology. Three-dimensional conformal PORT with a median total dose on clinical target volume of 50 (range 44–60) Gy was delivered to the tumor bed by 6–20 MV X-ray of the linear accelerator. Follow-up after radiotherapy was done by computed tomography scan every 6 months for 2 years and yearly thereafter. Results Two of the 22 patients developed local recurrence and four developed distant metastases. Median overall survival was 100 months, and the 3-year and 5-year survival rates were 83% and 74%, respectively. Median disease-free survival was 90 months, and the 5-year recurrence rate was 32%. On univariate analysis, pathologic stage III and presence of positive surgical margins had a significant impact on patient prognosis. Radiation toxicity was mild in most patients and no severe toxicity was registered. Conclusion Adjuvant radiotherapy achieved good local control and showed an acceptable toxicity profile in patients with high-risk thymoma. PMID:26089683

    This postmarketing surveillance study assessed the safety and effectiveness of teriparatide in patients with osteoporosis at high risk of fracture in Japan. The patients received teriparatide 20 μg daily by subcutaneous injection, for a maximum of 24 months. Safety and effectiveness analyses were based on data from 1,847 patients who were predominantly female (92.6%) with a mean age of 75.4 years. A total of 157 adverse drug reactions (ADRs) were reported in 140 (7.58%) patients; the most common ADRs were hyperuricemia, nausea, and dizziness. Only six (0.32%) patients reported serious ADRs, the most common being nausea (two patients; 0.1%). Persistence with teriparatide treatment was 60.8% and 39.1% at 18 and 24 months, respectively. There were significant increases in biomarkers for bone formation (procollagen type I N-terminal propeptide and bone-specific alkaline phosphatase) and bone resorption (collagen type I cross-linked C telopeptide and tartrate-resistant acid phosphatase 5b) throughout the study. These were accompanied by significant increases in bone mineral density and low incidences of new vertebral and nonvertebral fractures. Patient-reported measurements for health-related quality of life revealed significant improvements from baseline in back pain and overall health-related quality of life (Short Form-8™ health survey). The results of this 24-month postmarketing surveillance study imply that teriparatide has a favorable safety profile and is effective in the treatment of patients with osteoporosis at high risk of fracture in Japan. Teriparatide may also be a useful treatment for osteoporosis in other societies with aging populations. PMID:27462147

    Mobile devices have the potential to continuously monitor health by collecting movement data including walking speed during natural walking. Natural walking is walking without artificial speed constraints present in both treadmill and nurse-assisted walking. Fitness trackers have become popular which record steps taken and distance, typically using a fixed stride length. While useful for everyday purposes, medical monitoring requires precise accuracy and testing on real patients with a scientifically valid measure. Walking speed is closely linked to morbidity in patients and widely used for medical assessment via measured walking. The 6-min walk test (6MWT) is a standard assessment for chronic obstructive pulmonary disease and congestive heart failure. Current generation smartphone hardware contains similar sensor chips as in medical devices and popular fitness devices. We developed a middleware software, MoveSense, which runs on standalone smartphones while providing comparable readings to medical accelerometers. We evaluate six machine learning methods to obtain gait speed during natural walking training models to predict natural walking speed and distance during a 6MWT with 28 pulmonary patients and ten subjects without pulmonary condition. We also compare our model's accuracy to popular fitness devices. Our universally trained support vector machine models produce 6MWT distance with 3.23% error during a controlled 6MWT and 11.2% during natural free walking. Furthermore, our model attains 7.9% error when tested on five subjects for distance estimation compared to the 50-400% error seen in fitness devices during natural walking. PMID:25935052

    This study was aimed to assess the pulmonary function tests (PFTs) in cardiac patients; with ischemic or rheumatic heart diseases as well as in patients who underwent coronary artery bypass graft (CABG) or valvular procedures. For the forty eligible participants, the pulmonary function was measured using the spirometry test before and after the cardiac surgery. Data collection sheet was used for the patient's demographic and intra-operative information. Cardiac diseases and surgeries had restrictive negative impact on PFTs. Before surgery, vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), ratio between FEV1 and FVC, and maximum voluntary ventilation (MVV) recorded lower values for rheumatic patients than ischemic patients (P values were 0.01, 0.005, 0.0001, 0.031, and 0.035, respectively). Moreover, patients who underwent valvular surgery had lower PFTs than patients who underwent CABG with significant differences for VC, FVC, FEV1, and MVV tests (P values were 0.043, 0.011, 0.040, and 0.020, respectively). No definite causative factor appeared to be responsible for those results although mechanical deficiency and incisional chest pain caused by cardiac surgery are doubtful. More comprehensive investigation is required to resolve the case. PMID:23960642

    Malnutrition in patients with chronic obstructive pulmonary disease (COPD) is associated with cachexia, sarcopenia, and weight loss, and may result in poorer pulmonary function, decreased exercise capacity, and increased risk of exacerbations. Providing nutritional supplementation is an important therapeutic intervention, particularly for severely ill COPD patients with malnutrition. Higher calorie intake through nutritional supplementation significantly increases body weight and muscle strength, and improves quality of life in malnourished COPD patients. Difficulties may be experienced by these COPD patients, who are struggling to breathe and eliminate CO2 from the lungs, resulting in dyspnea, hypercapnia, hypoxia, and respiratory acidosis, which exacerbates muscle loss through oxidative stress and inflammatory responses. To overcome these problems, nutritional supplements should aim to reduce metabolic CO2 production, lower respiratory quotient, and improve lung function. Several studies have shown that high-fat supplements produce less CO2 and have lower respiratory quotient value than high-carbohydrate supplements. In addition, high-fat supplements may be the most efficient means of providing a low-volume, calorie-dense supplement to COPD patients, and may be most beneficial to patients with prolonged mechanical ventilation where hypercapnia and malnutrition are most pronounced. Further studies are required to investigate the optimal nutritional supplements for COPD patients according to their disease severity. PMID:26822811

    Pulmonary rehabilitation (PR) can improve aerobic exercise capacity, health-related quality of life and dyspnoea in patients with chronic obstructive pulmonary disease (COPD). Recent studies have suggested that exercise training may improve blood pressure and arterial stiffness, albeit in small highly selected cohorts. The aim of the study was to establish whether supervised outpatient or unsupervised home PR can reduce peripheral blood pressure. Resting blood pressure was measured in 418 patients with COPD before and after outpatient PR, supervised by a hospital-based team (HOSP). Seventy-four patients with COPD undergoing an unsupervised home-based programme acted as a comparator group (HOME). Despite significant improvements in mean (95% confidence interval) exercise capacity in the HOSP group (56 (50-60) m, p < 0.001) and HOME group (30 (17-42) m, p < 0.001) systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial blood pressure (MAP) did not change in either the HOSP (SBP: p = 0.47; DBP: p = 0.06; MAP: p = 0.38) or HOME group (SBP: p = 0.67; DBP: p = 0.38; MAP: p = 0.76). Planned subgroup analysis of HOSP patients with known hypertension and/or cardiovascular disease showed no impact of PR upon blood pressure. PR is unlikely to reduce blood pressure, and by implication, makes a mechanism of action in which arterial stiffness is reduced, less likely. PMID:26015460

    Chronic obstructive pulmonary disease (COPD) combines the deleterious effects of chronic hypoxia, chronic inflammation, insulin-resistance, increased energy expenditure, muscle wasting, and exercise deconditioning. As for other chronic disorders, loss of fat-free mass decreased survival. The preservation of muscle mass and function, through the protection of the mitochondrial oxidative metabolism, is an important challenge in the management of COPD patients. As the prevalence of the disease is increasing and the medical advances make COPD patients live longer, the prevalence of COPD-associated nutritional disorders is expected to increase in future decades. Androgenopenia is observed in 40% of COPD patients. Due to the stimulating effects of androgens on muscle anabolism, androgenopenia favors loss of muscle mass. Studies have shown that androgen substitution could improve muscle mass in COPD patients, but alone, was insufficient to improve lung function. Two multicentric randomized clinical trials have shown that the association of androgen therapy with physical exercise and oral nutritional supplements containing omega-3 polyinsaturated fatty acids, during at least three months, is associated with an improved clinical outcome and survival. These approaches are optimized in the field of pulmonary rehabilitation which is the reference therapy of COPD-associated undernutrition. PMID:24701566

    Preoperative chemoradiotherapy is the standard of care for locally advanced esophageal cancer, causing persistent deterioration in the nutritional status. We performed a prospective study to evaluate the safety and efficacy of esophageal double-covered self-expandable metal stents in patients with esophageal cancer before chemoradiotherapy. The nutritional status and dysphagia were prospectively recorded. Eleven patients were included: eight were moderate and three were severely malnourished. After stent placement, dysphagia improved in all patients. With regard to complications, one patient developed an esophageal perforation that required urgent esophagectomy. Four patients presented stent migration. Three of these patients required enteral nutrition and none was submitted to surgery because of poor nutritional status. Of the other six patients, only four were operated upon. Stent placement presented a high complication rate and did not prevent weight loss or malnutrition. Other alternatives, including naso-gastric tube placement or endoscopic percutaneous gastrostomy or jejunostomy, should be considered. PMID:26669568

    Surgical patients with pulmonary hypertension present a significant challenge to the anesthesiologist. Continuous perioperative monitoring of pulmonary artery (PA) pressure is recommended and most often accomplished with a PA catheter. Placement of a PA catheter may be difficult or contraindicated, and in these cases, transesophageal echocardiography is a useful alternative to monitor dynamic PA physiology. In this case, we used intraoperative transesophageal echocardiography to detect changes in peak PA pressure and guide clinical treatment in a patient with pulmonary hypertension and an extensive PA aneurysm undergoing partial nephrectomy.

    Background Splenic marginal zone lymphoma (SMZL) is a chronic B-cell lymphoproliferative disorder, comprising less than 2% of non-Hodgkin’s lymphomas, and affecting mainly middle-aged and elderly patients with a median survival of >10 years. The typical clinical features of SMZL include splenomegaly. Treatment should be patient-tailored and can range from a ‘watchful waiting’ approach for asymptomatic patients without cytopenias to surgery, localized radiation therapy or immuno/chemotherapies. Recently, the combination of rituximab and Bendamustine (R-Benda) has been defined as highly active in patients with follicular lymphomas, but little is known about the efficacy of R-Benda in SMZL. Aim of the study The purpose of this retrospective study was to report our experience on the efficacy of R-Benda as first line treatment in 23 consecutive elderly SMZL patients. Results All patients had a complete resolution of splenomegaly along with restoration of their blood counts. Nineteen patients (83%) achieved a complete response (CR) to therapy; three patients (13%) achieved a partial response (PR).Ten patients (43%) obtained molecular remission. Toxicities were mild and mainly haematological and result in dose reductions for fourteen patients. Conclusions Our data suggest a high activity and good tolerance of R-Benda, despite dose reduction due to potential toxicity. PMID:27413523

    The objective of this study was to evaluate retrospectively the clinical characteristics, treatments, and outcomes of patients with primary diffuse large B-cell lymphoma (DLBCL) of the female genital tract. The basic characteristics, treatments, and outcomes of six patients diagnosed with primary DLBCL of the female genital tract, including the ovary, uterine cervix, and vagina, treated in our hospital between 2000 and 2012, were analyzed retrospectively. Seven of 323 (2.2 %) newly diagnosed DLBCLs were diagnosed as primary female genital tract DLBCL. Six patients with complete medical data were included in the analysis. The median age at diagnosis was 52.5 years (range 20-65). The presenting symptoms included abnormal vaginal bleeding, increased vaginal discharge, abdominal fullness, and abdominal pain. Two patients had stage IE disease and four patients had stage IIE disease. Treatment included chemotherapy only in five patients, and combined chemotherapy and localized radiation in one patient. After a median follow-up of 58 months, four patients showed relapse in the central nervous system and two had died from progressive disease. The median progression-free survival was 27 months and the median overall survival for this group has not been reached. Patients with primary female genital tract DLBCL may have poor outcomes and a high risk of central nervous system relapse. Central nervous system prophylaxis might be considered in addition to systemic chemotherapy for DLBCL of the female genital tract. PMID:24408160

    To analyze the association between use of DPP-4 inhibitors and acute pancreatitis in high-risk type 2 diabetic patients. A retrospective nationwide cohort study was conducted using the Taiwan National Health Insurance claim database. The risk associated with sitagliptin was compared to that with acarbose, a second-line antidiabetic drug prescribed for patients with similar diabetes severity and with a known neutral effect on pancreatitis. Between January 1, 2009 and December 31, 2010, a total of 8526 sitagliptin initiators and 8055 acarbose initiators who had hypertriglyceridemia or prior hospitalization history for acute pancreatitis were analyzed for the risk of hospitalization due to acute pancreatitis stratified for baseline propensity score. In the crude analysis, sitagliptin was associated with a decreased risk of acute pancreatitis (hazard ratio [HR] 0.74; 95% confidence interval [CI]: 0.62-0.88) compared to acarbose in diabetic patients with prior history of hospitalization for pancreatitis or hypertriglyceridemia. The association was abolished after stratification for propensity score quintiles (adjusted HR 0.95; 95% CI: 0.79-1.16). Similar results were found separately in both patients' histories of prior hospitalization of acute pancreatitis (adjusted HR 0.97; 95% CI: 0.76-1.24) and those with hypertriglyceridemia (adjusted HR 0.86; 95% CI: 0.65-1.13). No significant association was found for different durations or accumulative doses of sitagliptin. In the stratified analysis, no significant effect modification was found in relation to patients' characteristics. Use of sitagliptin was not associated with an increased risk of acute pancreatitis in high-risk diabetic patients with hypertriglyceridemia or with history of acute pancreatitis. PMID:26886601

    Purpose: To evaluate long-term overall survival (OS), cancer-specific survival (CSS), clinical progression-free survival (cPFS), and health-related quality of life (HRQoL) following definitive radiotherapy (RT) given to T{sub 1-4p}N{sub 0}M{sub 0} prostate cancer patients provided by a single institution between 1989 and 1996. Methods and Materials: We assessed outcome among 203 patients who had completed three-dimensional conformal RT (66 Gy) without hormone treatment and in whom staging by lymphadenectomy had been performed. OS was compared with an age-matched control group from the general population. A cross-sectional, self-report survey of HRQoL was performed among surviving patients. Results: Median observation time was 10 years (range, 1-16 years). Eighty-one percent had high-risk tumors defined as T{sub 3-4} or Gleason score (GS) {>=}7B (4+3). Among these, 10-year OS, CSS, and cPFS rates were 52%, 66%, and 39%, respectively. The corresponding fractions in low-risk patients (T{sub 1-2} and GS {<=}7A [3+4]) were 79%, 95%, and 73%, respectively. Both CSS and cPFS were predicted by GS and T-classification; OS was associated with GS only. High-risk, but not low-risk, patients had reduced OS compared with the general population (p < 0.0005). When pelvis-related side effects were included in multivariate analyzes together with physical function and pain, sexual, urinary, and bowel function were not independently associated with self-reported global quality of life. Conclusions: Despite surgically proven {sub p}N{sub 0}, RT with dosage <70 Gy as monotherapy does not give satisfactory CSS rates after 10 years in patients with T{sub 3-4} or GS {>=}7B.

    Perioperative management of deaf and dumb patients can be a challenging task. For smooth postoperative recovery, proper care should begin in the preoperative period. Understanding the patients' needs and training him to follow the instructions requires to involve a communication specialist. Judicious use of sedatives and analgesics is essential to keep the patient pain-free and comfortable. Postoperatively, the patient should be kept awake, enough to understand the internal need of the body and to make a meaningful response to external stimuli. Adequate preoperative planning and coordinated team efforts with involvement of specialists can help in delivering better postoperative care. PMID:27397473

Nocardial brain abscesses are mainly found in patients with predisposing conditions such as pulmonary alveolar proteinosis (PAP), a disease associated with chronic exposure to silica dust. We present a case of multiple nocardial brain abscesses in a man with PAP probably due to long-term occupational exposure to silica dust. Conclusively, in patients presenting brain abscesses and a history of chronic exposure to silica dust, PAP and opportunistic nocardial infection should always be considered as possible diagnoses.

    Background Pulmonary abnormalities are found in both chronic heart failure (CHF) and pulmonary arterial hypertension (PAH). The differences of pulmonary function in chronic left heart failure and chronic right heart failure are not fully understood. Material/Methods We evaluated 120 patients with stable CHF (60 with chronic left heart failure and 60 with chronic right heart failure). All patients had pulmonary function testing, including pulmonary function testing at rest and incremental cardiopulmonary exercise testing (CPX). Results Patients with right heart failure had a significantly lower end-tidal partial pressure of CO2 (PetCO2), higher end-tidal partial pressure of O2 (PetO2) and minute ventilation/CO2 production (VE/VCO2) at rest. Patients with right heart failure had a lower peak PetCO2, and a higher peak dead space volume/tidal volume (VD/VT) ratio, peak PetO2, peak VE/VCO2, and VE/VCO2 slope during exercise. Patients with right heart failure had more changes in ΔPetCO2 and ΔVE/VCO2, from rest to exercise. Conclusions Patients with right heart failure had worse pulmonary function at rest and exercise, which was due to severe ventilation/perfusion (V/Q) mismatching, severe ventilation inefficiency, and gas exchange abnormality.

    In recent years, the use of herbal combinations, plant extracts or food supplements has increased in our country and all over the world. However, there is not enough data to determine the effective doses of these substances in the composition of herbal preparations, or their effects on metabolism and drug interactions. With the widespread use of herbal combinations, life-threatening side effects and clinical manifestations that arise from them have been reported. Herein we present a case with acute massive pulmonary embolism while using an herbal combination in the context of Tribulus terrestris, Avena sativa and Panax ginseng. A 41-year-old man was admitted to the emergency department with the complaint of sudden onset of dyspnea and syncope. As a result of investigations (blood gases, echocardiography, ventilation-perfusion scintigraphy) he was diagnosed with an acute massive pulmonary embolism. The patient's use of panax did not pose as a risk factor for the pulmonary embolism. He was given thrombolytic therapy and shortness of breath improved. At the pre-discharge the patient was informed of the risks associated with the herbal combination, especially panax. Coumadin was started and he was discharged for the INR checks to come.

  20. Evaluation of six CTLA-4 polymorphisms in high-risk melanoma patients receiving adjuvant interferon therapy in the He13A/98 multicenter trial

    2010-01-01

    Purpose Interferon is approved for adjuvant treatment of patients with stage IIb/III melanoma. The toxicity and uncertainty regarding survival benefits of interferon have qualified its acceptance, despite significant durable relapse prevention in a fraction of patients. Predictive biomarkers that would enable selection of patients for therapy would have a large impact upon clinical practice. Specific CTLA-4 polymorphisms have previously shown an association with response to CTLA-4 blockade in patients with metastatic melanoma and the development of autoimmunity. Experimental design 286 melanoma patients and 288 healthy controls were genotyped for six CTLA-4 polymorphisms previously suggested to be important (AG 49, CT 318, CT 60, JO 27, JO30 and JO 31). Specific allele frequencies were compared between the healthy and patient populations, as well as presence or absence of these in relation to recurrence. Alleles related to autoimmune disease were also investigated. Results No significant differences were found between the distributions of CTLA-4 polymorphisms in the melanoma population compared with healthy controls. Relapse free survival (RFS) and overall survival (OS) did not differ significantly between patients with the alleles represented by these polymorphisms. No correlation between autoimmunity and specific alleles was shown. The six polymorphisms evaluated where strongly associated (Fisher's exact p-values < 0.001 for all associations) and significant linkage disequilibrium among these was indicated. Conclusion No polymorphisms of CTLA-4 defined by the SNPs studied were correlated with improved RFS, OS, or autoimmunity in this high-risk group of melanoma patients. PMID:21044351

    The pathogenesis of chronic thromboembolic pulmonary hypertension (CTEPH) is unknown. Histopathologic studies revealed that pulmonary vasculature lesions similar to idiopathic pulmonary arterial hypertension (PAH) existed in CTEPH patients as well. It’s well-known that genetic predisposition plays an important role in the mechanism of PAH. So we hypothesized that PAH-causing gene mutation might exist in some CTEPH patients and act as a background to facilitate the development of CTEPH. In this study, we analyzed 7 PAH-causing genes including BMPR2, ACVRL1, ENG, SMAD9, CAV1, KCNK3, and CBLN2 in 49 CTEPH patients and 17 patients recovered from pulmonary embolism (PE) but without pulmonary hypertension(PH). The results showed that the nonsynonymous mutation rate in CTEPH patients is significantly higher than that in PE without PH patients (25 out of 49 (51%) CTEPH patients vs. 3 out of 17 PE without PH patients (18%); p = 0.022). Four CTEPH patients had the same point mutation in ACVRL1 exon 10 (c.1450C>G), a mutation approved to be associated with PH in a previous study. In addition, we identified two CTEPH associated SNPs (rs3739817 and rs55805125). Our results suggest that PAH-causing gene mutation might play an important role in the development of CTEPH.

    Photodynamic therapy (PDT) using aminolevulinic acid or its methyl ester, methyl-aminolevulinate (MAL), is an increasingly recognized approach for treating squamous neoplasia of the skin. Advantages of MAL-PDT include its ability to cover broad diseased areas (field treatment), and to do multiple sessions with little-to-no risk of scarring or mutagenesis. MAL-PDT is especially valuable in certain populations at high risk for skin cancer, including Caucasian patients with extensive solar damage, and organ transplant recipients (OTR) who take immunosuppressive drugs to prevent graft rejection. The latter group has a 65-200 fold increased risk of developing squamous cell carcinoma (SCC), a major cause of mortality. Therapeutic options for those patients, other than frequent surgeries, are very limited. Topical 5-Fluorouracil (5-FU), frequently prescribed in normal patients for pre-SCC of the skin, is only minimally effective in the OTR group. MAL-PDT, however, has ~40% efficacy for pre-SCC in OTR patients. Based upon our preclinical studies in mouse tumor models, which showed that preconditioning with 5-FU can drive higher accumulation of target protoporphyins (PpIX), we proposed a rational combination regimen of 5-FU and MAL-PDT in humans. A clinical trial was designed to test the hypothesis that a combination of 5-FU followed by MAL-PDT will elevate PpIX levels and achieve better clinical outcomes in high-risk OTR patients. Primary endpoints include PpIX levels and biochemical markers (p53) measured noninvasively and in skin biopsies. Lesion clearance and recurrence (via photographs and clinical exam) are secondary endpoints. Ongoing results of this clinical trial are presented.

    We aimed to identify tissue biomarkers that predict early biochemical recurrence (BCR) in patients with high-risk prostate cancer (PC), toward the goal of increasing the benefits of neoadjuvant hormonal therapy (NHT). In 2005-2012, prostatectomy specimens were collected from 134 PC patients who had received NHT and radical prostatectomy. The expression of 13 tissue biomarkers was assessed in the specimens via immunohistochemistry. Time to BCR and factors predictive of BCR were determined by using the Cox proportional hazards model. During the follow-up period (median, 57.5 months), 67 (50.0%) patients experienced BCR. Four (3.0%) patients were tumor-free in the final pathology assessment, and 101 (75.4%) had negative resection margins. Prostate stem cell antigen (PSCA) was the only significant prognostic tissue biomarker of BCR [hazard ratio (HR), 2.58; 95% confidence interval (CI), 1.06-6.27; p = 0.037] in a multivariable analysis adjusted by the clinicopathological variables that also significantly predicted BCR; these were seminal vesicle invasion (HR, 2.39; 95% CI, 1.32-4.34), initial prostate serum antigen level (HR 1.01; 95% CI, 1.001-1.020), prostate size (HR, 0.93; 95% CI, 0.90-0.97), and the Gleason score of preoperative biopsies (HR, 1.34; 95% CI, 1.01-1.79). We suggest that PSCA is a useful tissue marker for predicting BCR in patients with high risk PC receiving NHT and radical prostatectomy. PMID:26982980

    The role of reamberin, a succinate-containing infusion preparation in correlation of pulmonary metabolic and respiratory disturbances in patients with obstetric puerperal sepsis was estimated. The prospective randomized study enrolled 43 patients with puerperal obstetric sepsis complicated by polyorganic deficiency (SOFA 8-10). Nineteen patients of the 1st group and 24 patients of the 2nd group were additionally treated with reamberin in a dose of 800 ml/day for 8 days. The venous and arterial difference by glucose, lactate, pyruvate, diene conjugates, malondialdehyde and ceruloplasmin was investigated. The blood gases were determined with the Ciba Corning 45 apparatus. Lower metabolic activity of the lungs with prevalence of the glucose anaerobic metabolism and lower activity of the intrapulmonary antioxidant protection were observed in the patients with obstetric sepsis. The use of reamberin in the complex therapy of obstetric sepsis promoted maintenance of the initial balance and anaeroibic and aerobic pulmonary metabolism, thus providing shorter terms of the decompensation and recovery of the lungs respiratory function.

    The Taihang Mountain range of north-central China, the Southern region area of Fujian province, and the Chaoshan plain of Guangdong province are 3 major regions in China well known for their high incidence of esophageal cancer (EC). These areas also exhibit high incidences of gastric cardia cancer (GCC). The ancestors of the Chaoshanese, now the major inhabitants in the Chaoshan plain, were from north-central China. We hypothesized that EC and GCC patients in Chaoshan areas share a common ancestry with Taihang Mountain patients. We analyzed 16 East Asian-specific Y-chromosome biallelic markers (single nucleotide polymorphisms; Y-SNPs) and 6 Y-chromosome short tandem repeat (Y-STR) loci in 72 EC and 48 GCC patients from Chaoshan and 49 EC and 63 GCC patients from the Taihang Mountain range. We also compared data for 32 Chaoshan Hakka people and 24 members of the aboriginal She minority who live near the Chaoshan area. Analysis was by frequency distribution and principal component, correlation and hierarchical cluster analysis of Y-SNP. Chaoshan patients were closely related to Taihang Mountain patients, even though they are geographically distant. Y-STR analysis revealed that the 4 patient groups were more closely related with each other than with other groups. Network analysis of the haplogroup O3a3c1-M117 showed a high degree of patient-specific substructure. We suggest that EC and GCC patients from these 2 areas share a similar patrilineal genetic background, which may play an important role in the genetic factor of EC and GCC in these populations.

    BACKGROUND Acute kidney injury (AKI) is an important complication in surgical patients. Existing biomarkers and clinical prediction models underestimate the risk for developing AKI. We recently reported data from two trials of 728 and 408 critically ill adult patients in whom urinary TIMP2•IGFBP7 (NephroCheck, Astute Medical) was used to identify patients at risk of developing AKI. Here we report a preplanned analysis of surgical patients from both trials to assess whether urinary tissue inhibitor of metalloproteinase 2 (TIMP-2) and insulin-like growth factor–binding protein 7 (IGFBP7) accurately identify surgical patients at risk of developing AKI. STUDY DESIGN We enrolled adult surgical patients at risk for AKI who were admitted to one of 39 intensive care units across Europe and North America. The primary end point was moderate-severe AKI (equivalent to KDIGO [Kidney Disease Improving Global Outcomes] stages 2–3) within 12 hours of enrollment. Biomarker performance was assessed using the area under the receiver operating characteristic curve, integrated discrimination improvement, and category-free net reclassification improvement. RESULTS A total of 375 patients were included in the final analysis of whom 35 (9%) developed moderate-severe AKI within 12 hours. The area under the receiver operating characteristic curve for [TIMP-2]•[IGFBP7] alone was 0.84 (95% confidence interval, 0.76–0.90; p < 0.0001). Biomarker performance was robust in sensitivity analysis across predefined subgroups (urgency and type of surgery). CONCLUSION For postoperative surgical intensive care unit patients, a single urinary TIMP2•IGFBP7 test accurately identified patients at risk for developing AKI within the ensuing 12 hours and its inclusion in clinical risk prediction models significantly enhances their performance. LEVEL OF EVIDENCE Prognostic study, level I. PMID:26816218

    It has been suggested that pulmonary rehabilitation compined with inspiratory muscle training (IMT) might improve pulmonary function and respiratory muscle strength in elderly patients with chronic obstructive pulmonary disease (COPD). To test this hypothesis, inspiratory muscle strength (PImax), expiratory muscle strength (PEmax) and resting pulmonary function were measured in 13 elderly patients with COPD (aged 70.3 +/- 2.7 years). Inspiratory muscle training (IMT) was performed for 15 min twice a day, using a pressure threshold device, for a total of 12 weeks. The inspiratory threshold was set at 15% of maximal inspiratory pressure (PImax) for each individual. Pulmonary rehabilitation was performed for 12-h sessions over a 12-week period. Patients with COPD were assigned randomly to two groups: pulmonary rehabilitation combined with IMT (group A) (n = 7), and conventional pulmonary rehabilitation only (group B) (n = 6). Functional residual capacity (FRC) decreased significantly from 4.3 +/- 0.4 L at baseline to 3.9 +/- 0.4 L after rehabilitation (p < 0.01), Vp significantly increased from 4.6 +/- 0.8 L/sec at baseline to 5.1 +/- 0.7 L/sec after rehabilitation (p < 0.05) and the PImax increased significantly from 51.5 +/- 5.4 cmH2O at baseline to 80.9 +/- 7.0 cmH2O after rehabilitation (p < 0.02) in group A. However, these variables did not change in group B. There was no improvement in the 10-minutes walking distance of group A, but there was a significant increase in that of group B. It can be concluded that pulmonary rehabilitation combined with IMT improves pulmonary function and inspiratory muscle strength in elderly patients with COPD. PMID:9483953

    This single-center, observational case series involved a review of prospectively collected data pertaining to 16 V-Y fasciocutaneous advancement flaps performed on 16 consecutive patients between August 2006 and December 2008. Each patient underwent primary excision of a foot ulcer with debridement of soft tissue and bone, insertion of polymethylmethacrylate antibiotic-loaded bone cement, and immobilization. At an average of 3 days after the index procedure, soft tissue and osseous deformities were corrected in 13 of the 16 patients, and a V-Y fasciocutaneous advancement flap was used for coverage of the soft tissue defect in all patients. Patients were kept nonweightbearing and were followed up until clinical healing occurred or failure was declared. There were 12 male and 4 female patients with a mean age of 64.0 +/- 7.4 years (range, 48-75 years). Fifteen patients had diabetes mellitus with a mean of 5.1 +/- 1.8 (range, 3-8) medical comorbidities. There were 10 medial forefoot, 3 central forefoot, 2 lateral forefoot, and 1 dorsal midfoot full-thickness soft tissue defects that displayed a mean diameter of 2.3 +/- 1.4 cm (range, 1.0-3.5 cm). All but 4 flaps healed primarily, with each developing marginal dehiscence that healed with local wound care measures. Two deep infections occurred despite healing of the flap, which necessitated transmetatarsal amputation with split-thickness skin graft coverage. When properly performed and after complete resolution of infection, V-Y fasciocutaneous advancement flap coverage of complex foot ulcerations represents a useful and reliable technique even in patients with multiple medical comorbidities.

    Trauma during dental surgery is a predisposing factor for medication-related osteonecrosis of the jaws (MRONJ). There are no specific guidelines for the management of dental extractions in patients under bisphosphonate therapy (BPT). The authors proposed in 2013 a successful protocol for tooth extractions in patients under BPT supported by Nd:YAG low-level laser therapy (LLLT). The aim of this study was to validate the safety and efficacy of this protocol reporting the data related to its application in a particular category of patients under BPT at high risk for MRONJ and who were previously affected with MRONJ. Eighty-two tooth extractions were performed in 36 patients previously affected with MRONJ. Antibiotic treatment was administered 3 days before and 2 weeks after tooth extractions. Patients were additionally treated with Nd:YAG LLLT, 5 applications of 1 minute each. Patients were evaluated 3 days and once a week for 2 months after the extractions and every time they received LLLT. In a total of 82 extractions, minimal bone exposure was observed in 2 cases, treated with Er:YAG laser vaporization and then completely healed. The data confirmed that laser biostimulation is a reliable technique that can be considered in the surgical protocol for patients under BPT. PMID:25915674

    Both European Group for blood and marrow transplantation risk score (EBMT score modified model) and hematopoietic cell transplantation comorbidity index (HCT-CI) are suitable for evaluating patients undergoing unmanipulated haploidentical blood and marrow transplantation (HBMT), while the predictive capacity of the combined model following haploidentical transplantation is still unknown. In this study, we calculated and validated 322 consecutive unmanipulated HBMT patients. Patients in groups with HCT-CI scores of 0 or 1-2 exhibited similar overall survival (OS), non-relapse mortality (NRM), and relapse rates, independent of their EBMT score modified model. In the group in which patients' HCT-CI scores were ≥3, patients with high EBMT score modified model showed lower OS (p = 0.003) and higher NRM (p = 0.001) than did patients with low EBMT score. In conclusion, this combined model can be used to predict outcomes and may improve the stratification of high-risk patients following unmanipulated HBMT. PMID:26857549

    Background: Lactobacillus plantarum 299v (LP299v) has been used in order to reduce gastrointestinal symptoms during antibiotic exposure. However, it remains controversial whether or not probiotics are effective in the prevention of Clostridium difficile infections (CDI) among patients receiving antibiotics. The aim of this study was to analyze the CDI among patients receiving antibiotics and hospitalized in the period before and after starting routine use of LP299v as a prevention of this infection. Methods: Among 3533 patients hospitalized in the nephrology and transplantation ward during a two-year period, 23 patients with CDI were diagnosed and enrolled in this retrospective study. Since November 2013, prevention of CDI with oral use of LP299v was performed in all patients treated with antibiotics and who were at a high risk of developing CDI. The observation period was divided into two twelve-month intervals before and after initiation of the use of LP299v as a prophylactic against CDI. Results: A significant (p = 0.0001) reduction of the number of cases of CDI was found after routinely using LP299v (n = 2; 0.11% of all hospitalized patients) compared with the previous twelve-month period of observation (n = 21; 1.21% of all hospitalized patients). Conclusions: Routine use of LP299v during treatment with antibiotics may prevent C. difficile infection in the nephrology and transplantation ward. PMID:26690209

    Bacterial infections are common but have become increasingly resistant to drugs. The aim of the present study was to examine the combined treatment of traditional Chinese and Western medicine in 30 cases of pulmonary infection with multidrug resistant Acinetobacter baumannii. Patients were divided into groups A and B according to drug treatments. Cefoperazone or sulbactam and tanreqing were administered in group A, and cefoperazone or sulbactam in group B. The curative effect and prognosis of the two groups were recorded and the remaining treatments were performed routinely in the clinic. For the combined therapy group, which was administered sulperazone and tanreqing, 8 patients were recovered, 6 patients had significant effects, 3 patients exhibited some improvement and 1 patient had no response. One of the patients did not survive after 28 days. By contrast, there were 4 patients that were successfully treated, 3 patients with significant effects, 2 patients with some improvement and 2 patients had no response in the sulperazone group, and 4 patients did not survive after 28 days. In conclusion, the combined therapy of cefoperazone or sulbactam supplemented with tanreqing was identified to be more effective than cefoperazone or sulbactam as monotherapy, for treating multidrug resistant Acinetobacter baumannii.

    Patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) not fit for intensive treatment need novel therapy options. Vascular endothelial growth factor (VEGF) receptor inhibition is one potential mechanism by which AML and MDS could be treated. The receptor tyrosine kinase inhibitor AZD2171 (cediranib) has activity against VEGF receptors KDR and FLT-1. This multicenter phase II study was designed to test cediranib's activity in patients with AML or high-risk MDS. The primary endpoint was confirmed disease response defined as a composite of complete remission, partial remission or hematologic improvement. The study enrolled 23 subjects in the AML cohort and 16 subjects in the MDS cohort. There were no confirmed responses in either group. Since the study met the stopping rule after the first stage of enrollment, the trial was closed to further accrual. Common adverse events in both cohorts included thrombocytopenia, neutropenia, anemia, fatigue, dyspnea, diarrhea, nausea and dehydration. PMID:25329007

    Seven patients with venous thrombosis and contraindications to traditional thrombolytic therapy, consisting of recent intracranial surgery, recent pineal or retroperitoneal hemorrhage, active genitourinary or gastrointestinal bleeding, epidural procedures, and impending surgery, were successfully treated with a modified thrombolytic regimen. To improve safety, prolonged continuous infusions of tissue plasminogen activator (tPA) was eliminated in favor of once-daily low-dose intraclot injections of tPA to minimize the amount and duration of tPA in the systemic circulation, and low-therapeutic or regional anticoagulation was used to reduce anticoagulant risks. These modifications may allow thrombolytic treatment for selected patients with severe venous thrombosis who are deemed to be at high risk. PMID:23273695

    The purpose of this study was to evaluate the feasibility, safety and midterm outcome of elective implantation of the Carotid Wallstent (registered) in patients considered to be at high surgical risk. In a prospective study, 54 carotid artery stenoses in 51 patients were stented over a 24-month period. Three patients underwent bilateral carotid artery stenting. Institutional inclusion criteria for invasive treatment of carotid occlusive disease (carotid endarterectomy or carotid artery stenting) are patients presenting with a 70% or more symptomatic stenosis and those with an 80% or more asymptomatic stenosis having a life-expectancy of more than 1 year. All patients treated by carotid artery stenting were considered at high risk for carotid endarterectomy because of a hostile neck (17 patients-31.5%) or because of severe comorbidities (37 patients-68.5%). No cerebral protection device was used. Of the 54 lesions, 33 (61.1%) were symptomatic and 21 (38.8%) were asymptomatic. Follow-up was performed by physical examination and by duplex ultrasonography at 1 month, 6 months, 1 year and 2 years after the procedure. All 54 lesions could be stented successfully without periprocedural stroke. Advert events during follow-up (mean 13.9 {+-} 5.7 months) were non-stroke-related death in 6 patients (11.1%), minor stroke in 4 stented hemispheres(7.4%), transient ipsilateral facial pain in 1 patient (1.8%),infection of the stented surgical patch in 1 patient (1.8%) and asymptomatic in stent restenosis in 4 patients (7.4%). The percutaneous implantation of the Carotid Wallstent (registered) , even without cerebral protection device, appears to be a safe procedure with acceptable clinical and ultrasonographic follow-up results in patients at high surgical risk. But some late adverse events such as ipsilateral recurrence of non-disabling (minor) stroke or in stent restenosis still remain real challenging problems.

    Background Despite the development of a new class of antiemetics, postoperative nausea and vomiting (PONV) still remains a frequent and distressing complication. We compared the prophylactic antiemetic effect of administering dexamethasone 5 mg as an adjunct to ramosetron and ondansetron in patients at high-risk for PONV following lumbar spinal surgery. Methods In this randomized, double-blind study, 120 female non-smoking patients with intravenous patient-controlled analgesia (PCA) received ramosetron 0.3 mg plus dexamethasone 5 mg (group R + D) or ondansetron 4 mg plus dexamethasone 5 mg (group O + D) intravenously. Fentanyl-based PCA was administered for 48 hr postoperatively; ramosetron 0.3 mg or ondansetron 12 mg was added to the PCA regimen according to the allocated group. The incidence of PONV and rescue antiemetic were assessed for 48 hr postoperatively at 0-6, 6-24, and 24-48 hr. Results The overall incidence of PONV did not differ between the groups (50% vs. 60%, in groups R + D and O + D, respectively). The overall incidence of nausea was similar between groups (47% vs. 60%, in groups R + D and O + D, respectively). The overall frequency of vomiting was also similar between groups (8% vs. 12%, in groups R + D and O + D, respectively). The severity of nausea and the overall use of rescue antiemetic were not different between groups. Conclusions The antiemetic efficacy of ramosetron plus dexamethasone was similar to that of ondansetron plus dexamethasone on preventing PONV in high-risk patients undergoing lumbar spinal surgery.

    2010-09-01

    Pulmonary arterial hypertension (PAH) is a rare and potentially fatal disease whose management is usually restricted to a few specialised centres. As patients do not necessarily live in the neighbourhood of these centres, daily care and emergencies have to be delegated to first and second lines. Treatment guidelines do not usually provide recommendations for acute emergency situations as evidence is scarce. This short review provides a description of our therapeutic protocols based on available data. A model of transmural organisation of care for PAH patients, currently applied in Belgium, is described. Thereafter, based on an analysis of the reasons of death in the PAH population, a review of the main emergencies is provided. Cardiac arrest and resuscitation, decompensated right heart failure, respiratory failure, arrhythmia, pericardial effusion, haemoptysis, surgery and drug-related adverse events will be discussed successively. Case reports showing the precariousness of PAH patients will enforce our thesis of the need for optimal patient management organisation. PMID:20956193

    The HeartWare ventricular assist device (HVAD) is an implantable continuous-flow centrifugal pump that has allowed the development of sternal-sparing techniques, with the use of alternative outflow strategies. We compared early outcomes for patients bridged with the conventional versus alternative outflow graft strategy. From January 2013 to October 2014, 89 patients with HVAD implantation were identified. Survival was analyzed with Kaplan-Meier methods, and a log-rank test was used to compare outcomes between groups. Thirty patients (34%) had ≥1 previous sternotomy before HVAD implantation. Eight patients (27%) were approached using an alternative outflow graft technique with outflow graft connection to the descending aorta (n = 4, 50%) or left subclavian artery (n = 4, 50%), whereas 22 (73%) were implanted via a conventional sternotomy approach with the outflow graft to the ascending aorta. Preoperative characteristics (age, Interagency Registry for Mechanically Assisted Circulatory Support [INTERMACS], and Lietz-Miller score) were comparable between groups (all p > 0.05). Median follow-up was 4.7 (2.8-9.3) months of support. Outcomes were comparable between conventional and alternative outflow groups; survival at 6 months was 74% for the conventional group and 83% in the alternative outflow group. An alternative outflow graft strategy can be utilized to support bridged patients with a history of prior sternotomy. PMID:27111737

    Flying is the most important way of travelling in the continually growing international tourism. Number of passengers and those with preexisting diseases, mainly with cardiopulmonary problems, is increasing over years. One of the main tasks of the pre-travel advice is to assess tolerance to hypoxia of the traveler, and specify the necessity, as well as the type and volume of supplementary oxygen therapy. It is indispensable to know the cabin-environment and impact of that on the travelers' health. Travel medicine specialist has to be aware of the examinations which provide information for the appropriate decision on the fit-to-fly condition of the patient. The physician who prepares the patient with chronic obstructive pulmonary disease for repatriation by regular flight and the escorting doctor have to be fully aware of the possibilities, modalities, advantages and contraindications of the on-board oxygen supply and therapy. In this review, the authors give a summary of literature data, outline the tools of in-flight oxygen therapy as well as discuss possibilities for the preflight assessment of patients' condition including blood gas parameters required for safe air travel, as recommended in international medical literature. The preparation process for repatriation of patients with chronic obstructive pulmonary disease is also discussed. PMID:23434882

    Background Development of noninvasive molecular assays to improve disease diagnosis and patient monitoring is a critical need. In renal transplantation, acute rejection (AR) increases the risk for chronic graft injury and failure. Noninvasive diagnostic assays to improve current late and nonspecific diagnosis of rejection are needed. We sought to develop a test using a simple blood gene expression assay to detect patients at high risk for AR. Methods and Findings We developed a novel correlation-based algorithm by step-wise analysis of gene expression data in 558 blood samples from 436 renal transplant patients collected across eight transplant centers in the US, Mexico, and Spain between 5 February 2005 and 15 December 2012 in the Assessment of Acute Rejection in Renal Transplantation (AART) study. Gene expression was assessed by quantitative real-time PCR (QPCR) in one center. A 17-gene set—the Kidney Solid Organ Response Test (kSORT)—was selected in 143 samples for AR classification using discriminant analysis (area under the receiver operating characteristic curve [AUC] = 0.94; 95% CI 0.91–0.98), validated in 124 independent samples (AUC = 0.95; 95% CI 0.88–1.0) and evaluated for AR prediction in 191 serial samples, where it predicted AR up to 3 mo prior to detection by the current gold standard (biopsy). A novel reference-based algorithm (using 13 12-gene models) was developed in 100 independent samples to provide a numerical AR risk score, to classify patients as high risk versus low risk for AR. kSORT was able to detect AR in blood independent of age, time post-transplantation, and sample source without additional data normalization; AUC = 0.93 (95% CI 0.86–0.99). Further validation of kSORT is planned in prospective clinical observational and interventional trials. Conclusions The kSORT blood QPCR assay is a noninvasive tool to detect high risk of AR of renal transplants. Please see later in the article for the Editors' Summary PMID

    OBJECTIVES: This study assessed the outcome of implementing a policy of universal screening of patients with tuberculosis (TB) for HIV infection at a major metropolitan public health TB clinic. METHODS: HIV serologic testing was completed on 768 (93%) of 825 eligible patients. Ninety-eight HIV-positive cases (13%) were compared with 670 HIV-negative cases. The presence of adult HIV risk factors was determined by structured interview and review of medical records. RESULTS: One or more HIV risk factors were present in 93% of HIV-positive cases and 42% of HIV-negative cases. CONCLUSIONS: The metropolitan TB clinic is well suited for HIV screening, and HIV-antibody testing and counseling should be provided to all TB patients. PMID:9987468

    Standard first-line therapy for older patients with high-risk MDS consists of hypomethylating agents such as azacitidine (AZA). However, the only approach with curative potential remains allogeneic hematopoietic cell transplantation (HCT). So far no direct comparison of both strategies has been carried out. The outcomes of two well balanced cohorts of high-risk MDS patients defined by age (60–70 years), performance status (ECOG ≤2) and donor availability (yes/no) were compared including 103 patients undergoing HCT and 75 patients without this option who received AZA. The estimated 2-year overall survival (OS) after the start of treatment was 39% (95% CI, 30% to 50%) for the HCT patients and 23% (95% CI, 14 to 40%) for the AZA patients. In a multivariate Cox regression analysis of all (n=178) patients ECOG score (0 vs. 1 vs. 2, HR: 2.9/3.9, p<0.001), cytogenetics (good vs. intermediate vs. poor, HR: 1.2/1.7, p=0.026) and type of treatment (HCT vs. AZA, HR: 0.3, p=0.007) were associated with OS. This retrospective cohort analysis suggests a survival advantage with allogeneic HCT compared to treatment with AZA in medically fit high-risk MDS patients 60 to 70 years of age, Prospective controlled studies are warranted.

    Objective: To assess the value of parameters derived from arterial blood gas tests in the diagnosis of pulmonary embolism. Method: We measured alveolar-arterial partial pressure of oxygen [P(A–a)O2] gradient, PaO2 and arterial partial pressure of carbon diaxide (PaCO2) in 773 consecutive patients with suspected pulmonary embolism who were enrolled in the Prospective Investigative Study of Acute Pulmonary Embolism. Diagnosis: The study design required pulmonary angiography in all patients with abnormal perfusion scans. Results: Of 773 scans, 270 were classified as normal/near-normal and 503 as abnormal. Pulmonary embolism was diagnosed by pulmonary angiography in 312 of 503 patients with abnormal scans. Of 312 patients with pulmonary embolism, 12, 14 and 35% had normal P(A–a)O2, PaO2 and PaCO2, respectively. Of 191 patients with abnormal scans and negative angiograms, 11, 13 and 55% had normal P(A–a)O2, PaO2 and PaCO2, respectively. The proportions of patients with normal/near-normal scans who had normal P(A–a)O2, PaO2 and PaCO2 were 20, 25 and 37%, respectively. No differences were observed in the mean values of arterial blood gas data between patients with pulmonary embolism and those who had abnormal scans and negative angiograms. Among the 773 patients with suspected pulmonary embolism, 364 (47%) had prior cardiopulmonary disease. Pulmonary embolism was diagnosed in 151 (41%) of 364 patients with prior cardiopulmonary disease, and in 161 (39%) of 409 patients without prior cardiopulmonary disease. Among patients with pulmonary embolism, there was no difference in arterial blood gas data between patients with and those without prior CPD. Conclusion: These data indicate that arterial blood gas tests are of limited value in the diagnostic work-up of pulmonary embolism if they are not interpreted in conjunction with clinical and other laboratory tests.

    The increasing life expectancy in older adults and the better survival of patients with multiple pathologies require the capability to treat complex clinical conditions with an increased risk of iatrogenic complications. Nevertheless, recent improvements in the pharmacological and interventional treatment of acute coronary syndrome (ACS) have promoted a shift from therapeutic nihilism to a more active management of complex ACS cases. Despite the paucity of specific randomized clinical trials, observational studies seem to show benefit of an early invasive treatment in these patients. This approach requires close cooperation of clinical intensivists, interventional cardiologists and cardiovascular surgeons either in a specialized heart center or in a network of hospitals.

    A 42-year-old female patient of aplastic anaemia on maintenance blood transfusion presented with a 3-week history of fever, cough, dyspnoea and pedal oedema. Upon examination she  was found to have severe pallor, temperature of 101°F, tachycardia, bilateral pitting pedal oedema, raised jugular venous pressure, ejection systolic murmur (grade 2/6) in pulmonary area and petechiae over extensor aspect of both lower limbs. Blood investigations revealed low haemoglobin, thrombocytopaenia and mild increase in serum creatine. Chest x-ray was normal. Initial 2D trans thoracic echocardiography performed after hospital admission was normal. Antibiotics were started empirically to treat a possible underlying infection. Subsequently, three sets of blood cultures grew Enterococcus faecalis. Upon searching for the source, repeat echocardiograph done showed 2×0.5 cm vegetation on both pulmonary leaflets with severe pulmonary regurgitation, all other valves were free of vegetations. She was treated with intravenous antibiotics for the endocarditis and improved. PMID:23483061

    Background Lateral lumbar interbody fusion (LLIF) is not associated with many of the complications seen in other interbody fusion techniques. This study used computed tomography (CT) scans, the radiographic gold standard, to assess interbody fusion rates achieved utilizing the LLIF technique in high-risk patients. Methods We performed a retrospective review of patients who underwent LLIF between January 2008 and July 2013. Forty-nine patients underwent nonstaged or staged LLIF on 119 levels with posterior correction and augmentation. Per protocol, patients received CT scans at their 1-year follow-up. Of the 49 patients, 21 patients with LLIF intervention on 54 levels met inclusion criteria. Two board-certified musculoskeletal radiologists and the senior surgeon (JZ) assessed fusion. Results Of the 21 patients, 6 patients had had previous lumbar surgery, and the cohort's comorbidities included osteoporosis, diabetes, obesity, and smoking, among others. Postoperative complications occurred in 12 (57.1%) patients and included anterior thigh pain and weakness in 6 patients, all of which resolved by 6 months. Two cases of proximal junctional kyphosis occurred, along with 1 case of hardware pullout. Two cases of abdominal atonia occurred. By CT scan assessment, each radiologist found fusion was achieved in 53 of 54 levels (98%). The radiologists' findings were in agreement with the senior surgeon. Conclusion Several studies have evaluated LLIF fusion and reported fusion rates between 88%-96%. Our results demonstrate high fusion rates using this technique, despite multiple comorbidities in the patient population. Spanning the ring apophysis with large LLIF cages along with supplemental posterior pedicle screw augmentation can enhance stability of the fusion segment and increase fusion rates. PMID:24688329

    Background Carotid angioplasty and stenting (CAS) is an accepted treatment to prevent stroke in patients with carotid artery stenosis. The purpose of this study is to identify risk factors for major complications after CAS. Materials and Methods This is a prospective study that was conducted at Shiraz University of Medical Sciences in southern Iran from March 2011 to June 2014. Consecutive patients undergoing CAS were enrolled. Both standard- and high-risk patients for endarterectomy were enrolled. Demographic data, atherosclerotic risk factors, site of stenosis, degree of stenosis, and data regarding technical factors were recorded. Thirty-day stroke, myocardial infarction, and/or death were considered as the composite primary outcomes of the study. Results A total of 251 patients were recruited (mean age: 71.1 ± 9.6 years; male: 65.3%). Of these, 178 (70.9%) were symptomatic, 73 (29.1%) were diabetic, 129 (51.4%) were hyperlipidemic, 165 (65.7%) were hypertensive, and 62 (24.7%) patients were smokers. CAS was performed for left internal carotid artery (ICA) in 113 (45.4%) patients. Fourteen (5.6%) patients had sequential bilateral stenting. Mean stenosis of operated ICA was 80.2 ± 13.8%. An embolic protection device was used in 203 (96.2%) patients. Pre- and postdilation were performed in 39 (18.5%) and 182 (86.3%) patients, respectively. Composite outcomes were observed in 3.6% of patients (3.2% stroke, 0% myocardial infarction, and 1.2% death). Left-sided lesions and the presence of diabetes mellitus were significantly associated with poor short-term outcome (p = 0.025 and p = 0.020, respectively). Conclusion There was a higher risk of short-term major complications in diabetic patients and for left carotid artery intervention. PMID:26279663

    [Purpose] Video-assisted thoracic surgery and preoperative pulmonary rehabilitation are effective in preventing postoperative complications in patients with cardiopulmonary disease. The present study aims to elucidate the presence of postoperative pneumonia and atelectasis in patients with nontuberculous mycobacterial lung disease who underwent lung resection with video-assisted thoracic surgery and preoperative pulmonary rehabilitation. [Subjects and Methods] Nineteen patients with nontuberculous mycobacterial lung disease who had undergone lung resection with video-assisted thoracic surgery and preoperative pulmonary rehabilitation were enrolled in this study. The presence of postoperative pneumonia and atelectasis was evaluated, and preoperative and postoperative pulmonary functions were compared. [Results] Postoperative pneumonia and postoperative atelectasis were not observed. Decreases of pulmonary function were 5.9% (standard deviation, 8.5) in forced vital capacity (percent predicted) and 9.6% (standard deviation, 11.1) in forced expiratory volume in 1 s (percent predicted). [Conclusion] The present study indicates that the combination of lung resection with video-assisted thoracic surgery and preoperative pulmonary rehabilitation in patients with nontuberculous mycobacterial lung disease may be effective in preventing postoperative complications.

    The results of studies that evaluated predictive factors for rebleeding in non-variceal upper gastrointestinal bleeding are inconsistent. The aim of this study was to investigate predictive factors for 30-day rebleeding in these patients. A consecutive 312 patients presenting symptoms and signs of gastrointestinal bleeding were enrolled in this prospective, observational study. Clinical and demographic characteristics and endoscopic findings were evaluated for potential factors associated with 30-day rebleeding using logistic regression analysis. Overall, 176 patients were included (male, 80.1%; mean age, 59.7±16.0 yr). Rebleeding within 7 and 30 days occurred in 21 (11.9%) and 27 (15.3%) patients, respectively. We found that chronic kidney disease (CKD) (OR, 10.29; 95% CI, 2.84-37.33; P<0.001), tachycardia (pulse>100 beats/min) during the admission (OR, 3.79; 95% CI, 1.25-11.49; P=0.019), and Forrest classes I, IIa, and IIb (OR, 6.14; 95% CI, 1.36-27.66; P=0.018) were significant independent predictive factors for 30-day rebleeding. However, neither Rockall nor Blatchford scores showed statistically significant relationships with 30-day rebleeding in a multivariate analysis. CKD, hemodynamic instability during hospitalization, and an endoscopic high-risk appearance are significantly independent predictors of 30-day rebleeding in patients with non-variceal upper gastrointestinal bleeding. These factors may be useful for clinical management of such patients. PMID:24133356

    Introduction The colostomy is often necessary in complicated divertcular disease. The laparoscopic colostomy is not widely used for the treatment of complicated diverticular disease. Its use in patients with high operative risk is still on debate. The aim of this case report was to present the benefits of laparoscopic colostomy in patients with high peri-and postoperative risk factors. Presentation of case We present a case of 76-year-old female admitted to emergency unit for left colonic obstruction. The patient had a past history of liver cirrhosis HCV-related with a severe malnutrition, hypertrophic cardiomyopathy, diverticular disease, hiatal ernia, previous appendectomy. Patient was classified according to their preoperative risk ASA 3 (classification of the American society of Anestesia-ASA score). Contrast-enhanced abdominal CT revealed a marked thickening in the sigmoid colon and a marked circumferential stenosis in the sigmoid colon in absence of neoplasm, and/or abscess. The laparoscopic procedure is proposed as first intention. Discussion The operation time was 50 min, and the hospital stay was 4 days. Post operative complications grade I according to the Clavien Dindo Classification. Conclusions Laparoscopic colostomy is safe and feasible procedure in experienced hands. It is associated with low morbidity and short stay in hospital and should be considered a good alternative to a laparotomy. PMID:26036456

    Purpose IFNa was the first cytokine to demonstrate anti-tumor activity in advanced melanoma. Despite the ability of high-dose IFNa reducing relapse and mortality by up to 33%, large majority of patients experience side effects and toxicity which outweigh the benefits. The current study attempts to identify genetic markers likely to be associated with benefit from IFN-a2b treatment and predictive for survival. Experimental design We tested the association of variants in FOXP3 microsatellites, CTLA4 SNPs and HLA genotype in 284 melanoma patients and their association with prognosis and survival of melanoma patients who received IFNa adjuvant therapy. Results Univariate survival analysis suggested that patients bearing either the DRB1*15 or HLA-Cw7 allele suffered worse OS while patients bearing either HLA-Cw6 or HLA-B44 enjoyed better OS. DRB1*15 positive patients suffered also worse RFS and conversely HLA-Cw6 positive patients had better RFS. Multivariate analysis revealed that a five-marker genotyping signature was prognostic of OS independent of disease stage. In the multivariate Cox regression model, HLA-B38 (p = 0.021), HLA-C15 (p = 0.025), HLA-C3 (p = 0.014), DRB1*15 (p = 0.005) and CT60*G/G (0.081) were significantly associated with OS with risk ratio of 0.097 (95% CI, 0.013–0.709), 0.387 (95% CI, 0.169–0.889), 0.449 (95% CI, 0.237–0.851), 1.948 (95% CI, 1.221–3.109) and 1.484 (95% IC, 0.953–2.312) respectively. Conclusion These results suggest that gene polymorphisms relevant to a biological occurrence are more likely to be informative when studied in concert to address potential redundant or conflicting functions that may limit each gene individual contribution. The five markers identified here exemplify this concept though prospective validation in independent cohorts is needed. PMID:22911710

    Purpose To investigate whether the integrity (completeness) of pulmonary fissures affects pulmonary function in patients with chronic obstructive pulmonary disease (COPD). Materials and Methods A dataset consisting of 573 CT exams acquired on different subjects was collected from a COPD study. According to the global initiative for chronic obstructive lung disease (GOLD) criteria, these subjects (examinations) were classified into five different subgroups, namely non-COPD (222 subjects), GOLD-I (83 subjects), GOLD-II (141 subjects), GOLD-III (63 subjects), and GOLD-IV (64 subjects), in terms of disease severity. An available computer tool was used to aid in an objective and efficient quantification of fissure integrity. The correlations between fissure integrity, and pulmonary functions (e.g., FEV1, and FEV1/FVC) and COPD severity were assessed using Pearson and Spearman's correlation coefficients, respectively. Results For the five sub-groups ranging from non-COPD to GOLD-IV, the average integrities of the right oblique fissure (ROF) were 81.8%, 82.4%, 81.8%, 82.8%, and 80.2%, respectively; the average integrities of the right horizontal fissure (RHF) were 62.6%, 61.8%, 62.1%, 62.2%, and 62.3%, respectively; the average integrities of the left oblique fissure (LOF) were 82.0%, 83.2%, 81.7%, 82.0%, and 78.4%, respectively; and the average integrities of all fissures in the entire lung were 78.0%, 78.6%, 78.1%, 78.5%, and 76.4%, respectively. Their Pearson correlation coefficients with FEV1 and FE1/FVC range from 0.027 to 0.248 with p values larger than 0.05. Their Spearman correlation coefficients with COPD severity except GOLD-IV range from −0.013 to −0.073 with p values larger than 0.08. Conclusion There is no significant difference in fissure integrity for patients with different levels of disease severity, suggesting that the development of COPD does not change the completeness of pulmonary fissures and incomplete fissures alone may not contribute to the

  16. Improvement in toxicity in high risk prostate cancer patients treated with image-guided intensity-modulated radiotherapy compared to 3D conformal radiotherapy without daily image guidance

    PubMed Central

    2014-01-01

    Background Image-guided radiotherapy (IGRT) facilitates the delivery of a very precise radiation dose. In this study we compare the toxicity and biochemical progression-free survival between patients treated with daily image-guided intensity-modulated radiotherapy (IG-IMRT) and 3D conformal radiotherapy (3DCRT) without daily image guidance for high risk prostate cancer (PCa). Methods A total of 503 high risk PCa patients treated with radiotherapy (RT) and endocrine treatment between 2000 and 2010 were retrospectively reviewed. 115 patients were treated with 3DCRT, and 388 patients were treated with IG-IMRT. 3DCRT patients were treated to 76 Gy and without daily image guidance and with 1–2 cm PTV margins. IG-IMRT patients were treated to 78 Gy based on daily image guidance of fiducial markers, and the PTV margins were 5–7 mm. Furthermore, the dose-volume constraints to both the rectum and bladder were changed with the introduction of IG-IMRT. Results The 2-year actuarial likelihood of developing grade > = 2 GI toxicity following RT was 57.3% in 3DCRT patients and 5.8% in IG-IMRT patients (p < 0.001). For GU toxicity the numbers were 41.8% and 29.7%, respectively (p = 0.011). On multivariate analysis, 3DCRT was associated with a significantly increased risk of developing grade > = 2 GI toxicity compared to IG-IMRT (p < 0.001, HR = 11.59 [CI: 6.67-20.14]). 3DCRT was also associated with an increased risk of developing GU toxicity compared to IG-IMRT. The 3-year actuarial biochemical progression-free survival probability was 86.0% for 3DCRT and 90.3% for IG-IMRT (p = 0.386). On multivariate analysis there was no difference in biochemical progression-free survival between 3DCRT and IG-IMRT. Conclusion The difference in toxicity can be attributed to the combination of the IMRT technique with reduced dose to organs-at-risk, daily image guidance and margin reduction. PMID:24495815

    Introduction: Psychiatric disorders, especially anxiety and depression have been reported to have an increased prevalence in chronic obstructive pulmonary disease (COPD) patients, but there is a paucity of data from India. Aims and Objectives: Aim of our study is to study the frequency of psychiatric comorbidities in COPD patients and their correlation with severity of COPD, as per global initiative for obstructive lung disease guidelines. Materials and Methods: This study was conducted in outpatient department of a tertiary care hospital (King George's Medical University). A total of 74 COPD patients were included in this study and compared with 74 controls. The diagnosis and severity of COPD were assessed by spirometry. Psychiatric comorbidities were assessed using the Mini International Neuropsychiatric Interview questionnaire. Results: The frequency of psychiatric comorbidities was significantly higher (P < 0.05) in COPD patients (28.4%) as compared to controls (2.7%). As regards to severity, the frequency was significantly increased in severe and very severe COPD. The frequency of psychiatric comorbidities in COPD patients increased significantly with the increase in duration of symptoms being present in 67% of patients with duration of symptoms more than 10 years and only 23% of patients with duration of symptoms ≤5 years. Conclusion: The frequency of psychiatric comorbidities is increased in COPD patients as compared to controls. We recommend that all patients with COPD should be screened for psychiatric comorbidity, if any. PMID:27051106

    Background: The ratio of systolic blood pressure (SBP) to heart rate (HR), called the reverse shock index (RSI), is used to evaluate the hemodynamic stability of trauma patients. A SBP lower than the HR (RSI < 1) indicates the probability of hemodynamic shock. The objective of this study was to evaluate whether the RSI as evaluated by emergency medical services (EMS) personnel at the injury scene (EMS RSI) and the physician in the emergency department (ED RSI) could be used as an additional variable to identify patients who are at high risk of more severe injury. Methods: Data obtained from all 16,548 patients added to the trauma registry system at a Level I trauma center between January 2009 and December 2013 were retrospectively reviewed. Only patients transferred by EMS were included in this study. A total of 3715 trauma patients were enrolled and subsequently divided into four groups: group I patients had an EMS RSI ≥1 and an ED RSI ≥1 (n = 3485); group II an EMS RSI ≥ 1 and an ED RSI < 1 (n = 85); group III an EMS RSI < 1 and an ED RSI ≥ 1 (n = 98); and group IV an EMS RSI < 1 and a ED RSI < 1 (n = 47). A Pearson’s χ2 test, Fisher’s exact test, or independent Student’s t-test was conducted to compare trauma patients in groups II, III, and IV with those in group I. Results: Group II and IV patients had a higher injury severity score, a higher incidence of commonly associated injuries, and underwent more procedures (including intubation, chest tube insertion, and blood transfusion in the ED) than patients in group I. Group II and IV patients were also more likely to receive a severe injury to the thoracoabdominal area. These patients also had worse outcomes regarding the length of stay in hospital and intensive care unit (ICU), the proportion of patients admitted to ICU, and in-hospital mortality. Group II patients had a higher adjusted odds ratio for mortality (5.8-times greater) than group I patients. Conclusions: Using an RSI < 1 as a threshold

    It is widely recognised that low-density lipoprotein cholesterol (LDL-C) is one of the most important and modifiable risk factors for cardiovascular disease (CVD). Statins (HMG-CoA reductase inhibitors) have consistently been shown to decrease both LDL-C and CVD risk in almost all patient categories, with the exception of heart and kidney failure as well as advanced aortic stenosis. As a consequence, statins have become the cornerstone in current prevention guidelines. In patients who do not reach the LDL-C target, combination therapy with additional LDL-C lowering drugs (e.g. ezetimibe, bile acid sequestrants or fibrates) should be considered. Guidelines provide different LDL-C levels to strive for, depending on the CVD risk. In this review, we describe the rationale for these LDL-C targets and how these goals might be reached by current and future therapies. PMID:23494186

    Tuberculosis is an uncommon but recognized cause of hypercalcaemia, though calcium levels are seldom severely elevated and rarely result in symptoms. In the elderly patient however, several competing aetiologies may contribute to hypercalcaemia and the diagnostic evaluation may be confounded by polypharmacy as well as multiple co-existing medical conditions. We present here a case of an elderly man who presented with pulmonary tuberculosis and concomitant delirium secondary to hypercalcaemic crisis. Treatment with anti-tuberculous drugs, together with supportive care, eventually led to resolution of hypercalcaemia and restoration of mental function. PMID:26566450

    In contrast to the results of previous studies, recent randomized controlled trials (RCTs) failed to show a benefit of prophylactic aortic counterpulsation in high-risk patients undergoing cardiac surgery. The present analysis aims to redefine the effects of this treatment modality in the light of this new evidence. MEDLINE, EMBASE, CENTRAL/CCTR, Google Scholar and reference lists of relevant articles were searched for full-text articles of RCTs in English or German. Assessments for eligibility, relevance, study validity and data extraction were performed by two reviewers independently using prespecified criteria. The primary outcome was hospital mortality. A total of nine eligible RCTs with 1171 patients were identified: 577 patients were treated preoperatively with intra-aortic balloon pump (IABP) and 594 patients served as controls. The pooled odds ratio (OR) for hospital mortality (22 hospital deaths in the intervention arm, 54 in the control group) was 0.381 (95% CI 0.230-0.629; P < 0.001). The pooled analyses of five RCTs including only patients undergoing isolated on-pump coronary artery bypass grafting (n[IABP] = 348, n[control] = 347) also showed a statistically significant improvement in mortality for preoperative IABP implantation (fixed-effects model: OR 0.267, 95% CI 0.129-0.552, P < 0.001). The pooled OR for hospital mortality from two randomized off-pump trials was 0.556 (fixed-effects model, 95% CI 0.207-1.493, P = 0.226). Preoperative aortic counterpulsation was associated with a significant reduction in low cardiac output syndrome (LCOS) in the total population (fixed-effects model: OR 0.330, 95% CI 0.214-0.508, P < 0.001) as well as in the subgroup of CAGB patients (fixed-effects model: OR 0.113, 95% CI 0.056-0.226, P < 0.001), whereas there was no benefit in the off-pump population (fixed-effects model: OR 0.555, 95% CI 0.209-1.474, P = 0.238). Preoperative IABP implantation was associated with a reduction of intensive care unit (ICU) stay in

    Background Guidelines endorse statin therapy for lowering low-density lipoprotein cholesterol (LDL-C) to recommended levels, in patients with cardiovascular disease (CVD) risk, if needed, after lifestyle changes. Atorvastatin is a common statin with greater LDL-C lowering efficacy than most other statins; its availability in generic form will likely increase its use. This study assessed attainment of guideline-recommended LDL-C levels in high-risk CVD patients treated with atorvastatin monotherapy. Methods Analyses of two retrospective US cohorts of patients who received a prescription for atorvastatin monotherapy between January 1, 2008 and December 31, 2010 (index date defined as first prescription date) in the GE Centricity Electronic Medical Record (EMR) (N=10,693) and Humana Medicare (N=16,798) databases. Eligible patients were ≥18 years, diagnosed with coronary heart disease or atherosclerotic vascular disease, with ≥1 LDL-C measurement between 3 months and 1 year postindex date, and continuously enrolled for 1 year prior to and following the index date. Results Of the eligible patients, 21.8%, 29.6%, 29.9%, and 18.7% (GE Centricity EMR) and 25.4%, 32.9%, 27.8%, and 14.0% (Humana Medicare) received 10, 20, 40, and 80 mg doses of atorvastatin, respectively. The mean ± standard deviation (SD) follow-up LDL-C levels were 2.1±0.8 mmol/L (83±30 mg/dL) and 2.3±0.8 mmol/L (88±31 mg/dL) for the GE Centricity EMR and Humana Medicare cohorts, respectively. Regardless of dose, only 28.3%–34.8% of patients had LDL-C levels <1.8 mmol/L (<70 mg/dL), and 72.0%–78.0% achieved LDL-C <2.6 mmol/L (<100 mg/dL) in both cohorts. As many as 41% and 13% of patients had LDL-C levels ≥0.5 mmol/L (≥20 mg/dL) above LDL-C 1.8 mmol/L (70 mg/dL) and 2.6 mmol/L (100 mg/dL), respectively, in both cohorts; these percentages were generally similar across atorvastatin doses. Conclusion In this real-world US setting, a large number of high-risk CVD patients did not attain

    The acute myeloid leukaemia (AML)14 trial addressed four therapeutic questions in patients predominantly aged over 60 years with AML and High Risk Myelodysplastic Syndrome: (i) Daunorubicin 50 mg/m(2) vs. 35 mg/m(2); (ii) Cytarabine 200 mg/m(2) vs. 400 mg/m(2) in two courses of DA induction; (iii) for part of the trial, patients allocated Daunorubicin 35 mg/m(2) were also randomized to receive, or not, the multidrug resistance modulator PSC-833 in a 1:1:1 randomization; and (iv) a total of three versus four courses of treatment. A total of 1273 patients were recruited. The response rate was 62% (complete remission 54%, complete remission without platelet/neutrophil recovery 8%); 5-year survival was 12%. No benefits were observed in either dose escalation randomization, or from a fourth course of treatment. There was a trend for inferior response in the PSC-833 arm due to deaths in induction. Multivariable analysis identified cytogenetics, presenting white blood count, age and secondary disease as the main predictors of outcome. Although patients with high Pgp expression and function had worse response and survival, this was not an independent prognostic factor, and was not modified by PSC-833. In conclusion, these four interventions have not improved outcomes in older patients. New agents need to be explored and novel trial designs are required to maximise prospects of achieving timely progress. PMID:19291085

    While there are studies postulating a model of synergism between human papillomavirus (HPV) and herpes simplex virus (HSV) in cervical carcinogenesis, the frequency of anal herpes as well as its association with anal squamous intraepithelial lesions (ASILs) has been understudied in men. This study evaluates the frequency of HSV changes in anal Pap smears and its association with ASILs in a high-risk population. A computerized search for specimens associated with anal cytology that had positive findings of HSV was performed. The electronic medical records were examined for past diagnosis of herpes, HSV serology prior to or after cytology, and if the patient received treatment after cytologic diagnosis of HSV. Of the 470 anal Pap smears (Thin-prep) examined, seven had cellular changes consistent with HSV infection. All patients were asymptomatic human immunodeficiency virus (HIV) positive males with no prior HSV serology tests. Two patients had prior diagnoses of HSV infection. Cytologic abnormalities were identified in 86% ranging from atypical squamous cells of undetermined significance to high grade squamous intraepithelial lesion. Three patients were treated after the HSV cytologic diagnosis. The frequency of HSV changes in anal Pap smear is low (1.48%), but the presence of concomitant cytologic abnormalities is high (86%). While our findings suggest the possible role of HSV as a HPV co-factor in ASILs, larger studies are needed to support this. Identification of HSV infection on anal Pap smear is important for institution of patient treatment and subsequent reduction of transmission. PMID:24692314

From January 2006 throughout 2012, 250 liver transplants were evaluated and 54 patients identified as being at higher risk were randomly selected to undergo the following schedule: 28 patients received liposomal amphotericin B and 26 received caspofungin. We evaluated, throughout 12 months, renal and liver function tests, bacterial and fungal infection episodes, and intensive care unit (ICU) stay, as well as the Th1 and Th2 cytokine network. Differences were analyzed according to non-parametric tests (two-tailed p values). Neither of the groups showed episodes of invasive fungal infection during the 12 months follow-up; however, patients receiving prophylaxis with liposomal amphotericin B had reduced episodes of bacterial infections coupled with an improved immune system response compared with those receiving caspofungin. Finally, a reduced stay in the ICU was also observed. In conclusion, even if the results of liposomal amphotericin B and caspofungin prophylaxis strategies did not differ in terms of invasive fungal infection rate, patients receiving prophylaxis with liposomal amphotericin B had a reduced ICU stay and an improved Th2 status, as well as a reduced number of post-transplant bacterial infections. Further studies are required to better address and evaluate these findings. PMID:26513601

    The role of hemopoietic stem cell transplantation (HSCT) is not well established in certain types of lymphoma, such as those with a high relapse risk or relapsing after initial therapy. New chemotherapeutic schemes and immunotherapy have improved survival of these patients. Nevertheless, there is not enough evidence regarding whether transplantation is the best therapeutic approach. Moreover, published data on long-term follow-up of high-risk lymphoma patients treated with HSCT are scarce. We analyzed 177 consecutive patients diagnosed with a high risk of relapse or with relapsed lymphoma who underwent HSCT after induction with standard chemotherapy in a tertiary academic center from 1989 to 2013. The median age was 40 years. Diagnoses were Hodgkin disease (n = 56), diffuse large B-cell lymphoma (n = 44), follicular lymphoma (n = 29), mantle cell lymphoma (n = 15), T-cell lymphoma (n = 18), and others (n = 15). Patients received either an autologous graft (n = 154) in first complete remission (1CR; n = 59) or more advanced stages (AS; n = 95), or an allogeneic graft (n = 23) in 1CR (n = 4) or AS (n = 19). In the autologous group, overall survival (OS) at 5 years was 57% and 75% in the periods 1989-2001 and 2002-2013, respectively (P = .05). Patients receiving an allogeneic graft presented an OS of 25% and 43% in the 2 periods. With a mean follow-up of 5 years (95% confidence interval 3.5-6.6), for patients receiving a transplant in 1CR, OS at 5 years was 80%, and for those receiving a transplant in AS it was 59% (P = .003). Nonrelapse mortality (NRM) at 5 years was 3.1% in the autologous group and 27.9% in the allogeneic group (P < .001). The main cause of NRM was infection (44%) in the whole cohort. All this leads to the conclusion that transplantation, as a therapeutic strategy, has shown a high long-term OS in this subgroup of patients with such a poor prognosis. OS improved over the years and reaching 1CR was a good prognostic feature. Infections were the main

    Background: Intraindividual variability in neurophysiological responses is an important factor in the study of schizophrenia. Interestingly, this variability strongly predicts individual differences in cognitive processing. Neurobiological abnormalities that present during the prodromal phase of schizophrenia are not well characterized. However, these symptoms may provide insight into the key circuits involved in the disorder. Aims: To investigate the variability in magnetoencephalographic responses at ultrahigh risk and schizophrenia patients. Methods: Twenty-four ultrahigh risk, 21 patients with schizophrenia and 28 healthy controls were evaluated. The intraindividual variability was estimated by calculating the s.d. of the across-trial amplitude in responses to deviant and standard stimuli. The degree of phase locking across trials was calculated by intertrial coherence. Results: Greater variability in the responses to deviant and standard tones was noted in the schizophrenia and ultrahigh risk groups compared with controls. Variability in response to standard stimuli was positively correlated with the amplitude for the standard stimuli in all of the groups. Moreover, schizophrenia patients displayed lower alpha and theta intertrial coherence compared with ultrahigh risk and controls. Mismatch negativity amplitude was correlated with the alpha intertrial coherence in all groups. Taken together, the augmented variability and reduced inter-trial coherence provide empirical evidence for increased amplitude and phase inconsistencies in schizophrenia and ultrahigh risk. Conclusions: The results implicate widespread dysfunction in amplitude modulation and phase concentration in schizophrenia and ultrahigh risk, as well as evidence for early amplitude and phase disruption. These finding suggest intraindividual variability and intertrial coherence appear to be important indicators of pathophysiological processing. PMID:27336039

    Background and Objectives Prognostic value of additional carotid Doppler evaluations to carotid intima-media thickness (IMT) and plaque has not been completely evaluated. Subjects and Methods A total of 1119 patients with risk factors for, but without, overt coronary artery disease (CAD), who underwent both carotid ultrasound and Doppler examination were included in the present study. Parameters of interest included peak systolic and end-diastolic velocities, resistive indices of the carotid arteries, IMT, and plaque measurements. The primary end-point was all-cause cerebro-cardiovascular events (CVEs) including acute myocardial infarction, coronary revascularization therapy, heart failure admission, stroke, and cardiovascular death. Model 1 covariates comprised age and sex; Model 2 also included hypertension, diabetes and smoking; Model 3 also had use of aspirin and statin; and Model 4 also included IMT and plaque. Results The mean follow-up duration was 1386±461 days and the mean age of the study population was 60±12 years. Amongst 1119 participants, 43% were women, 57% had a history of hypertension, and 23% had diabetes. During follow-up, 6.6% of patients experienced CVEs. Among carotid Doppler parameters, average common carotid artery end-diastolic velocity was the independent predictor for future CVEs after adjustments for all models variables (HR 0.95 per cm/s, 95% confident interval 0.91-0.99, p=0.034 in Model 4) and significantly increased the predictive value of Model 4 (global χ2=59.0 vs. 62.8, p=0.029). Conclusion Carotid Doppler measurements in addition to IMT and plaque evaluation are independently associated with future CVEs in asymptomatic patients at risk for CAD. PMID:26798388

    Background Cholesterol gallstone disease (GS) is highly prevalent among Hispanics and American Indians. In GS, the pool of bile acids (BA) is decreased, suggesting that BA absorption is impaired. In Caucasian GS patients, mRNA levels for ileal BA transporters are decreased. We aimed to determine fecal BA excretion rates, mRNA levels for ileal BA transporter genes and of regulatory genes of BA synthesis in Hispanic GS patients. Results Excretion of fecal BA was measured in seven GS females and in ten GS-free individuals, all with a body mass index < 29. Participants ingested the stool marker Cr2O3 (300 mg/day) for 10 days, and fecal specimens were collected on the last 3 days. Chromium was measured by a colorimetric method, and BA was quantitated by gas chromatography/mass spectroscopy. Intake of calories, nutrients, fiber and cholesterol were similar in the GS and GS-free subjects. Mean BA excretion levels were 520 ± 80 mg/day for the GS-free group, and 461 ± 105 mg/day for the GS group. Messenger RNA expression levels were determined by RT-PCR on biopsy samples obtained from ileum during diagnostic colonoscopy (14 GS-free controls and 16 GS patients) and from liver during surgery performed at 8 and 10 AM (12 GS and 10 GS-free patients operated on for gastrointestinal malignancies), all with a body mass index < 29. Messenger RNA level of the BA transporter genes for ileal lipid binding protein, multidrug resistance-associated protein 3, organic solute transporter alpha, and organic solute transporter beta were similar in GS and GS-free subjects. Messenger RNA level of Cyp27A1, encoding the enzyme 27α-hydroxylase, the short heterodimer partner and farnesoid X receptor remained unchanged, whereas the mRNA level of Cyp7A1, the rate limiting step of BA synthesis, was increased more than 400% (p < 0.01) in the liver of GS compared to GS-free subjects. Conclusion Hispanics with GS have fecal BA excretion rates and mRNA levels of genes for ileal BA transporters that

    Patients with familial hypercholesterolemia or statin intolerance are especially challenging to manage since LDL cholesterol levels often remain considerably elevated despite clinicians' best efforts. With statins regarded as first-line pharmacologic therapy by the current American College of Cardiology/American Heart Association guidelines to reduce LDL cholesterol and cardiovascular risk, there is now a critical need to determine when other agents will play a role beyond maximally tolerated statin therapy and lifestyle changes. In this review, we take a closer look at evolocumab (Repatha(®)), one of the new injectable human monoclonal antibodies to PCSK9 and its efficacy and safety properties from the results of various trials.

    Purpose To compare the surgical outcomes of limbal-based and fornix-based trabeculectomy in eyes with a history of ocular incisional surgery. Methods Twenty-six eyes underwent limbal-based trabeculectomy (group LB), and were condition matched with 26 eyes that received fornix-based trabeculectomy (group FB). Surgical failure was recorded retrospectively if the intraocular pressure value was either ≥21, ≥18, and ≥15 mmHg (conditions A, B, and C, respectively) or <4 mmHg or if the patient required additional glaucoma surgery. Kaplan–Meier survival curve analysis was used to assess surgical failure. Results For condition A, the 2 year surgical success probabilities were 75.0% and 63.9% in groups FB and LB, respectively (P=0.124). The corresponding values were 55.0% and 61.7% (P=0.638) in condition B, and 55.0% and 57.0% (P=0.454) in condition C. The rates of bleb leakage, hypotony, choroidal detachment, and bleb-related infection were 11.5%, 26.9%, 50.0%, and 7.7% in group LB, respectively. The corresponding values in group FB were 30.8%, 23.1%, 46.2%, and 0.0%, which were not statistically different between the two groups. Conclusion No significant differences in surgical outcomes were observed between limbal-based and fornix-based trabeculectomy for patients with a history of incisional ocular surgeries. PMID:24868145<
