    Ventilation and perfusion lung scans were obtained before and at weekly intervals following hip surgery or major amputation in 158 patients. Pulmonary arteriograms were obtained in 21 of 33 patients developing perfusion patterns strongly suggesting embolism; 19 of the 21 arteriograms demonstrated pulmonary embolism. From autopsy and clinical data, 36 patients were diagnosed as having an embolus while under study, and 12 patients were suspected of having had an embolus during their illness but prior to entry into the study. Only four of these 48 patients experienced symptoms suggestive of pulmonary embolism. We conclude that asymptomatic pulmonary embolism is a common event in the populations studied. PMID:7059242

    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.

    The objectives of this pilot trial were to assess the safety of a new device for pulmonary embolism (PE) prophylaxis. The device, the Angel Catheter, was placed in eight patients who were in the intensive care unit and were at high risk of PE. The device was inserted at the bedside without fluoroscopic guidance via a femoral venous approach. All eight devices were inserted and subsequently retrieved without complications (follow-up, 33-36 d). One filter trapped a large clot.

    Thrombus-in-transit is not uncommon in pulmonary embolism but Right Heart Transvalvular Embolus (RHTVE) complicating this is rare. A 54-year-old obese male with recent hospitalization presented with severe dyspnea and collapse. Initial investigations revealed elevated d-dimer and troponin. CTA showed saddle pulmonary embolus and bedside echocardiogram revealed right ventricular (RV) pressure overload and dilatation (RV > 41 mm), McConnell's sign, and mobile echodensity attached to tricuspid valve. Patient was immediately resuscitated and promptly transferred for surgical embolectomy under cardiopulmonary bypass. A long segment of embolus traversing through the tricuspid valve and extensive bilateral pulmonary artery embolus were removed. IVC filter was placed for a persistent right lower extremity DVT. Hypercoagulable work-up was negative. Patient continued to do well after discharge on Coumadin. Open embolectomy offers great promises where there is no consensus in optimal management approach in such patients. Bedside echocardiogram is vital in risk stratification and deciding choice of advanced PE treatment.

    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.

    Introduction. We sought to identify possible risk factors associated with mortality in patients with high-risk pulmonary embolism (PE) after intensive care unit (ICU) admission. Patients and Methods. PE patients, diagnosed with computer tomography pulmonary angiography, were included from two ICUs and were categorized into groups: group 1 high-risk patients and group 2 intermediate/low-risk patients. Results. Fifty-six patients were included. Of them, 41 (73.2%) were group 1 and 15 (26.7%) were group 2. When compared to group 2, need for vasopressor therapy (0 vs 68.3%; p < 0.001) and need for invasive mechanical ventilation (6.7 vs 36.6%; p = 0.043) were more frequent in group 1. The treatment of choice for group 1 was thrombolytic therapy in 29 (70.7%) and anticoagulation in 12 (29.3%) patients. ICU mortality for group 1 was 31.7% (n = 13). In multivariate logistic regression analysis, APACHE II score >18 (OR 42.47 95% CI 1.50–1201.1), invasive mechanical ventilation (OR 30.10 95% CI 1.96–463.31), and thrombolytic therapy (OR 0.03 95% CI 0.01–0.98) were found as independent predictors of mortality. Conclusion. In high-risk PE, admission APACHE II score and need for invasive mechanical ventilation may predict death in ICU. Thrombolytic therapy seems to be beneficial in these patients.

    The initial theoretical concept of a polypill was a fixed-dosed combination pill containing an antiplatelet agent, a cholesterol-lowering agent and multiple blood pressure-lowering agents aimed at the prevention of atherosclerotic vascular disease in the population aged 55 years and up. The reduction in the risk of cardiovascular disease does not depend on the cholesterol level and blood pressure at the start of treatment. The pharmacological reduction in risk factors in individuals with a high risk of atherosclerotic vascular disease is often suboptimal, partly due to the complexity of the guidelines and low adherence to the therapy. A polypill may offer opportunities for improvement. Research has shown that the use of combination products leads to a greater reduction in risk factors than the use of separate substances, possibly through improved adherence to the therapy. The use of a polypill in the prevention of vascular disease in high-risk patients may lead to a more effective reduction in risk, a decrease in costs and a reduction in pharmacological expenditure.

    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.

    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

    Objectives. Patients with high-risk prostate cancer undergoing radical prostatectomy, external beam radiation therapy (EBRT) combined with androgen deprivation therapy (ADT) or ADT alone. The widely accepted definition of high-risk prostate was first proposed by D'Amico based on a pretreatment Gleason score of ≥8, clinical stage T3, PSA level ≥20 ng/mL. There is no trial that compares traditional methods of treatment of such patients with HIFU therapy. Here we explored the effectiveness of the HIFU in multimodal treatment for patients with high risk prostate cancer. Materials & Methods. 701 patients with high risk prostate cancer were treated in our center between September 2007 and December 2013. Gleason score were 8-10, stage T3N0M0, age 69 (58-86) years, mean PSA before treatment 43.3 (22.1-92.9) ng/ml, mean prostate volume - 59.3 (38-123) cc. 248 patients were treated by HIFU. We compare this group of patients with patients who undertook EBRT: number 196, and ADT: number 257. Mean follow-up time 58 months (6-72). Results. The 5-year overall survival rates in patients after HIFU were 73.8 %, after EBRT - 63.0 % and after ADT - 18.1%. Conclusions. Our experience showed that HIFU therapy in combined treatment were successful for high risk prostate cancer.

    Care managers embedded in primary care clinics work with patients with high-risk diagnoses and multiple visits to the emergency department or hospital. Patients are identified though risk assessments, suggestions from inpatient case management, and requests from primary care clinicians. Care managers call patients before their clinic visits, look for gaps in care and find out patients' questions and concerns, sharing the information with the treating clinicians. Care managers follow patients for four weeks after their visit, helping them meet their health care goals and follow their treatment plan.

    Atherosclerotic cardiovascular diseases remain the leading cause of morbidity and mortality in both developed and developing countries. Adequate treatment of vascular risk factors, such as low-density lipoprotein cholesterol and systolic blood pressure are known to reduce the future risk of cardiovascular disease in these patients. However currently, large treatment gaps exist among high-risk individuals, in whom the guidelines recommend concomitant treatment with aspirin, statin, and blood-pressure lowering agents. Combining aspirin, cholesterol, and blood-pressure lowering agents into a single pill called the cardiovascular polypill has been proposed as complementary care in the prevention of cardiovascular diseases in both intermediate- and high-risk patient populations. It is now a decade since the first recommendations to develop and trial cardiovascular polypills. The major scientific debate has been about the appropriate initial target population. This review article focuses on the potential role of fixed-dose combination therapy in different patient populations, outlines the pros and cons of combination therapy, and emphasizes the rationale for trialing their use. Current and planned future cardiovascular polypill trials are summarized and the pre-requisites for implementation of the polypill strategy in both primary and secondary prevention are described. The recent development of combination pills containing off-patent medications holds promise for highly affordable and effective treatment and evidence is emerging on the use of this strategy in high-risk populations.

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

    To explore perceptions of high-risk patients and their practice staff on the patient-centered medical home, we conducted a multisite qualitative study with chronically ill, low-income patients and their primary care practice staff (N = 51). There were 3 key findings. Both patients and staff described a trade-off: timely care from an unfamiliar provider versus delayed access to their personal physician. Staff were enthusiastic about enhancing access through strategies such as online communication, yet high-risk patients viewed these as access barriers. Practices lacked capacity to manage high-risk patients and therefore frequently referred them to the emergency room.

    A clinician-driven home monitoring program can improve interstage outcomes in single-ventricle patients. Sociodemographic factors have been independently associated with mortality in interstage patients. We hypothesized that even in a population with high-risk sociodemographic characteristics, a home monitoring program is effective in reducing interstage mortality. We defined interstage period as the time period between discharge following Norwood palliation and second-stage surgery. We reviewed the charts of patients for the three-year period before (group 1) and after (group 2) implementation of the home monitoring program. Clinical variables around Norwood palliation, during the interstage period, and at the time of second-stage surgery were analyzed. There were 74 patients in group 1 and 52 in group 2. 59 % patients were Hispanic, and 84 % lived in neighborhoods where over 5 % families lived below poverty line. There was no significant difference in pre-Norwood variables, Norwood discharge variables, age at second surgery, or outcomes at second surgery. There were more Sano shunts performed at the Norwood procedure as the source of pulmonary blood flow in group 2 (p value <0.05). There were more unplanned hospital admissions and percutaneous re-interventions in group 2. Patients in group 2 whose admission criteria included desaturation had a 45 % likelihood of having an unplanned re-intervention. Group 2 noted an 80 % relative reduction in interstage mortality (p < 0.01). In a multiple regression analysis, after accounting for ethnicity, socio-economic status, and source of pulmonary blood flow, enrollment in a home monitoring program independently predicted improved interstage survival (p < 0.01). A clinician-driven home monitoring program reduces interstage mortality even when the majority of patients has high-risk sociodemographic characteristics.

    -C should be lowered to < 100 mg/dL. Statin is necessary for DM patients with CV disease and the LDL-C target is < 70 mg/dL. For diabetic patients who are ≥ 40 years of age, or who are < 40 years of age but have additional CV risk factors, the LDL-C target should be < 100 mg/dL. After achieving LDL-C target, combination of other lipid-lowering agents with statin is reasonable to attain TG < 150 mg/dL and HDL-C >40 in men and >50 mg/dL in women in DM. LDL-C increased CV risk in patients with CKD. In adults with glomerular filtration rate (GFR) < 60 mL/min/1.73m(2) without chronic dialysis (CKD stage 3-5), statin therapy should be initiated if LDL-C ≥ 100 mg/dL. Ezetimibe can be added to statin to consolidate the CV protection in CKD patients. Mutations in LDL receptor, apolipoprotein B and PCSK9 genes are the common causes of FH. Diagnosis of FH usually depends on family history, clinical history of premature CAD, physical findings of xanthoma or corneal arcus and high levels of LDL-C. In addition to conventional lipid lowering therapies, adjunctive treatment with mipomersen, lomitapide, or PCSK9 inhibitors become necessary to further reduce LDL-C in patients with FH. Overall, these recommendations are to help the health care professionals in Taiwan to treat hyperlipidemia with current scientific evidences. We hope the prescription rate of lipid lowering drugs and control rate of hyperlipidemia in high risk patients could be increased by implementation of the clinical guidelines. The major purpose is to improve clinical outcomes of these high risk patients through the control of hyperlipidemia.

    An imbalance of proinflammatory cytokines such as TNF-alpha, IL-1 beta, and the neutrophil chemotactic factor IL-8 and inhibitors (e.g., soluble TNF receptors and IL-1ra) in the lung during the first week of life may contribute to prolonged pulmonary inflammation and fibrosis in bronchopulmonary dysplasia (BPD). Disodium cromoglycate (DSCG) has anti-inflammatory effects in asthma, a disease with many similarities with BPD. In a prospective, randomized, blinded study, we examined whether early DSCG therapy inhibits proinflammatory cytokines in infants at risk for BPD. Twenty-six infants who were identified as high risk (> or = 75% probability) for oxygen-dependency at 28 d by a 12-h predictive score and survived 48 h were randomized to nebulized DSCG 20 mg (n = 13) or 2 cc NS (control, n = 13) every 6 h from Day 3 to Day 28. Lung lavage was collected on Day 3 (pre-study) and Day 7 and analyzed for cell count and differential and TNF-alpha, sTNFR1, sTNFR2, IL-1 beta, IL-1ra, and IL-8 concentrations. The groups' pre-study lavage cytokine concentrations were similar, but TNF-alpha and IL-8 concentrations were 3.6- and 4.9-fold lower in the DSCG group on Day 7 compared with levels in the control group. Soluble TNF receptors were unaffected by DSCG. There was a trend towards lower IL-1 beta levels in DSCG-treated infants on Day 7, but IL-1ra levels were unaffected by DSCG therapy. Three control subjects, but no DSCG-treated infants, died during the study period (p = 0.07). There were no significant differences between survivors of the two groups for oxygen-dependency at 28 d (100% control subjects; 85% DSCG). These results suggest that nebulized DSCG may exert an anti-inflammatory effect in the lungs of infants < or = 1,000 g at risk for BPD.

    Background High-risk prostate cancer treatment has been controversial. Some high-risk prostate cancer patients fail to respond to radical prostatectomy only. Thus, we aimed to investigate the predictive factors for biochemical recurrence (BCR) and identify patients who could achieve sufficient therapeutic effect by radical prostatectomy only. Methods Of 264 medical records reviewed, 141 low-intermediate-risk and 100 high-risk prostate cancer patients, excluding those who had received neoadjuvant hormone therapy, were analyzed. BCR was defined as the first increase in prostate-specific antigen levels (≥ 0.2 ng/mL), with levels not decreasing to undetectable limits, after radical prostatectomy. Log-rank test and Cox proportional hazards regression analyses were performed to determine the prognostic factors. We investigated the perioperative predictive factors for BCR and BCR-free survival rates, with the number of National Comprehensive Cancer Network (NCCN) high-risk factors for high-risk prostate cancer patients who underwent robot-assisted radical prostatectomy. Results Multivariate analyses showed that clinical T3 was significantly associated with BCR [hazard ratio (HR) = 4.052; 95% confidence interval (CI), 1.26–12.99; P = 0.019]. Of the 100 patients, 77 had 1 high-risk factor and 23 had ≥ 2 high-risk factors; the 1-year BCR-free survival rate of patients with 1 high-risk factor and those with ≥ 2 high-risk factors was 94.8% and 69.6%, respectively. Patients with ≥ 2 high-risk factors were significantly associated with BCR (P = 0.002). No difference in BCR rate between patients with 1 high-risk factor and those with low- and intermediate-risk was found. Conclusion High-risk prostate cancer patients with 1 NCCN high-risk factor can be considered for robot-assisted radical prostatectomy treatment only. PMID:28070166

    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

    Dyspnea occurs in most cancer patients and is often associated with severe pain. Pulmonary rehabilitation has become increasingly important to improve ADL and QOL and to relieve pain that results from dyspnea. Although pulmonary rehabilitation is now provided mainly during the perioperative period, it has been recognized as an effective procedure for patients before, during, or after chemotherapy or radiotherapy. It is also useful for patients with advanced or terminal cancer. However, an evidence-based cancer rehabilitation procedure has to be established.

    Objective To evaluate the benefit of robot-assisted radical prostatectomy (RARP) in the low-risk prostate cancer (PCa) patients suitable for active surveillance and in the high-risk PCa patients who would be considered for alternative treatments such as radiotherapy (RT) and androgen deprivation therapy (ADT) instead of radical prostatectomy. Material and methods Of 548 patients, who underwent RARP, 298 PCa patients (258 low-risk and 40 high-risk) with a mean of 3.6 years follow-up, were included into this study. Oncological outcomes were compared separately in low- and high-risk PCa patients. Results The pathologic Gleason scores were ≥7 in 73 (28%), and 68 (26%) patients had a pathologic stage of T3, 29 (11%) patients had a positive surgical margin (PSM), and 20 (7%) patients had biochemical recurrence (BCR) in the first year follow-up in the low-risk group. Of 258 low-risk PCa patients, a total of 93 (36%) patients had not either BCR, pathologic Gleason score ≥7, or ≥pT3 disease with PSM. In the high-risk group, the pathologic stage was pT2 in 14 (35%) patients and 29 (72%) patients had no biochemical recurrence in the follow-up of these high-risk PCa patients. Of 40 high-risk PCa patients, in a total of 25 (62.5%) patients ≥pT3b disease, BCR, pT3a disease with PSM were not detected. Conclusion Approximately two thirds of high-risk PCa patients benefit from RARP without additional RT or ADT. Besides, more than one third of low-risk PCa patients who fit active surveillance criteria would have unfavorable results. PMID:28270949

    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.

    Abstract 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. PMID:26717394

    Purpose: The introduction of transcatheter aortic valves has focused attention on the results of conventional aortic valve surgery in high-risk patients. The aim of the study was to evaluate 5-years outcomes in this category of patients in the current surgical era. Methods: This is an observational retrospective study of 581 high-risk patients undergoing aortic valve replacement from 2008 to 2013, with a mean logistic EuroSCORE of 26.6% ± 14.6%. Data were prospectively collected in a database of Emilia-Romagna region (Italy). Results: Overall 30-day mortality was 9.3%. Stroke rate was 1.5%. At 1-, 3-, and 5-years overall mortality was 18.2%, 30.4%, and 42.2%, cardiac death rate was 3.9%, 9.2%, and 12.9%, stroke rate 2.5%, 7.7%, and 10.2%, re-operation occurrence 0.2%, 0.9% and 1.3%, and new pacemaker implantation was 2.3%, 5.1% and 7.8%. At multivariate analysis, urgency, hemodynamic instability, LVEF ≤30%, NYHA III-IV, severe chronic obstructive pulmonary disease (COPD), extra-cardiac arteriopathy, cerebrovascular disease, and creatinine >2.0 mg/dL remained independent predictors of 5-year mortality. Conclusion: The results of the current study add weight to the evidence that traditional aortic valve replacement can be performed in high-risk patients with satisfactory 5-year mortality and morbidity. Our study may help to improve decision-making in this category of high-risk patients with aortic valve disease. PMID:27645551

    Presents opportunities to increase the effectiveness of combination antihypertensive therapy (AHT) in patients with arterial hypertension (AH) and high cardiovascular risk. Displaying increase in the proportion of patients with target blood pressure up to 82.4%; high commitment combined AHT (96%) and medical recommendations for lifestyle changes (54%) using the power of information computer technology (ICT) in order to carry out continuous monitoring of blood pressure and other risk factors (RF), commitment to the patients drug and non-drug assignments. Thus, ICT can be seen as a tool that can give a real idea of the scale and nature of the deviation from the medical recommendations that can serve as a basis for personalized AHT.

    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.

    The complexity of treating concurrent pain and opioid dependence among many methadone-maintained individuals presents a major challenge in many clinical settings. Furthermore, recent expert guidelines have called for increased research on the safety of methadone in the context of chronic pain. This study explores the prevalence and correlates of pain among a prospective cohort of people who use illicit drugs in Vancouver, British Columbia, Canada, who reported enrollment in methadone maintenance treatment (MMT) between 2011 and 2014. Among the 823 participants eligible for this analysis, 338 (40.9%) reported moderate pain and 91 (11.1%) reported extreme pain at the first study visit. In multivariable, generalized, linear mixed model analyses, higher pain severity was positively and independently associated with self-managing pain (adjusted odds ratio [AOR] 2.15, 95% confidence interval [CI] 1.77-2.60), patient perception of methadone dose being too low (AOR 1.82, 95% CI 1.41-2.34), older age (AOR 1.31, 95% CI 1.13-1.51), having a physical disability (AOR 4.59, 95% CI 3.73-5.64), having ever been diagnosed with a mental illness (AOR 1.44, 95% CI 1.13-1.84), white ethnicity (AOR 1.42, 95% CI 1.10-1.83), and marijuana use (AOR 1.25, 95% CI 1.02-1.52). These findings suggest several areas for clinical intervention, particularly related to patient education and alternative analgesic approaches for MMT patients experiencing pain. Perspective: To better understand the complexity of concurrent pain and opioid dependency among individuals on methadone maintenance treatment, this article describes the prevalence and correlates of higher pain severity among methadone-maintained people who use illicit drugs. Patients on methadone with comorbid pain may benefit from education and alternative analgesic approaches.

    Pulmonary hypertension in end-stage renal disease patients is associated with significantly increased morbidity and mortality. The prevalence of pulmonary hypertension in dialysis patients is relatively high and varies in different studies from 17% to 49.53% depending on the mode of dialysis and other selection factors, such as the presence of other cardiovascular comorbidities. The etiopathogenic mechanisms that have been studied in relatively small studies mainly include arteriovenous fistula-induced increased cardiac output, which cannot be accomodated by, the spacious under normal conditions pulmonary circulation. Additionally, pulmonary vessels show signs of endothelial dysfunction, dysregulation of vascular tone due to an imbalance in vasoactive substances, and local as well as systemic inflammation. It is also believed that microbubbles escaping from the dialysis circuit can trigger vasoconstriction and vascular sclerosis. The non-specific therapeutic options that proved to be beneficial in pulmonary artery pressure reduction are endothelin inhibitors, phosphodiesterase inhibitor sildenafil, and vasodilatory prostaglandins in various forms. The specific modes of treatment are renal transplantation, size reduction or closure of high-flow arteriovenous fistulas, and transfer from hemodialysis to peritoneal dialysis-a modality that is associated with a lesser prevalence of pulmonary hypertension.

    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 off-pump coronary artery bypass (OPCAB) grafting in high risk patients remains controversial. While there have been studies showing the potential benefits of it, there is still a lot to be learned from the application of this technique in this sub-group of patients. The results of the different trials and papers that we reviewed seem to indicate a benefit in the OPCAB group. Despite of the fact that trials were significantly different in methodology, especially when choosing the risk score stratification tool or the cut-off to define high risk the literature seems to suggest a benefit from the use of OPCAB surgery. Here, we present a review which focussed on early and late outcome in high risk patients undergoing on- and off-pump coronary revascularization. PMID:27942397

    During the 1984-1985 influenza season two study groups were used to compare telephone and letter reminder methods with a control group that received no reminder to determine which was the most effective strategy to increase influenza vaccination rates among the high-risk patient population of a university-based family practice. Seven hundred eighty-seven high-risk patients were randomly assigned to one of the three study groups: a mailed-reminder group, a telephone-reminder group, and a control group. Vaccination rates for both reminder methods were significantly higher than for the control group (P less than .02), and if successfully contacted, the telephone-reminder group had a significantly better vaccination rate than the mailed-reminder group (P less than .05). If successful telephone contact can be made, this reminder method is more effective than a letter reminder to increase influenza vaccination rates among high-risk patients.

    The aim of this study was to assess long-term mortality and predictive factors of death after hospital admission for acute exacerbation of chronic obstructive pulmonary disease (COPD). 1824 patients (23.2% female; mean age 70.3±11.3 years) consecutively admitted for acute exacerbation of COPD in the respiratory medicine departments of 68 general hospitals between October 2006 and June 2007 were prospectively enrolled in a follow-up cohort. Their vital status was documented between October 2010 and April 2011. Vital status was available for 1750 patients (95.9%), among whom 787 (45%) died during follow-up. 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

    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.

    Predicting negative outcomes, such as readmission or death, and detecting high-risk patients are important yet challenging problems in medical informatics. Various models have been proposed to detect high-risk patients; however, the state of the art relies on patient information collected before or at the time of discharge to predict future outcomes. In this paper, we investigate the effect of including data generated post discharge to predict negative outcomes. Specifically, we focus on two types of patients admitted to the Vanderbilt University Medical Center between 2010-2013: i) those with an acute event - 704 hip fractures and ii) those with chronic problems — 5250 congestive heart failure (CHF) patients. We show that the post-discharge model improved the AUC of the LACE index, a standard readmission scoring function, by 20 - 30%. Moreover, the new model resulted in higher AUCs by 15 - 27% for hip fracture and 10 - 12% for CHF compared to standard models. PMID:28269914

    Dialectical behavioral therapy (DBT) programs, particularly for low-functioning individuals at the safety and stabilization phase of therapy, work with a variety of high-risk and often complex cases, with a curriculum consisting primarily of concrete skill acquisition and application. A significant subset of individuals in DBT programs, however, may suffer high-risk dissociative episodes in which skill application may be less available to them, contributing to further destabilization, demoralization, and thoughts of self-inefficacy in treatment. This article evaluates the potential benefits of complementing traditional DBT with psychoeducation on structural dissociation for such patients, acknowledging and addressing some of the concerns that might accompany such a consideration.

    Purpose The goal of this study was to compare the rate of systemic inflammatory response syndrome (SIRS) in high-risk patients undergoing percutaneous nephrolithotomy (PCNL) between patients who received 7, 2, or 0 days of preoperative antibiotics. Materials and Methods We retrospectively reviewed a series of consecutive PCNLs performed at our institution. Patients with infected preoperative urine cultures were excluded. High-risk patients were defined as those with a history of previous urinary tract infection (UTI), hydronephrosis, or stone size ≥2 cm. Patients were treated with 7, 2, or 0 days of preoperative antibiotic prophylaxis prior to PCNL. All patients received a single preoperative dose of antibiotics within 60 minutes of the start of surgery. Fisher exact test was used to compare the rate of SIRS by preoperative antibiotic length. Results Of the 292 patients identified, 138 (47.3%) had sterile urine and met high-risk criteria, of which 27 (19.6%), 39 (28.3%), and 72 (52.2%) received 7, 2, and 0 days of preoperative antibiotics, respectively. The 3 groups were similar in age, sex, and duration of surgery (p>0.05). There was no difference in the rate of SIRS between the groups, with 1 of 27 (3.7%), 2 of 39 (5.1%) and 3 of 72 patients (4.2%) meeting criteria in the 7, 2, and 0 days antibiotic groups (p=~1). Conclusions Extended preoperative antibiotic prophylaxis was not found to reduce the risk of SIRS after PCNL in our institutional experience of high-risk patients. For these patients, a single preoperative dose of antibiotics is sufficient. PMID:27847915

    The purpose of this paper was to present morphological characteristics of potentially malignant nodules revealed in a group of male smokers aged 50-74 with a very high risk for developing lung cancer estimated in the study for lung cancer screening in Cracow (Poland). Nine hundred male smokers aged 50 to 74 years were invited to the study and were asked in questionnaires about e.g. smoking exposure history. Exclusion criteria included e.g. positive cancer history and chest computed tomography (CT) examination in the previous year. Based on CT results and characteristics of pulmonary nodules subjects were classified to group A (low risk), group B (indeterminate) and group C (high-risk individuals - required work-up). Final diagnosis was based on pathological results of postoperative material. Thirty-nine males of mean age 63.4 (standard deviation (SD): 6.69 years) revealed 41 potentially malignant pulmonary nodules in baseline screening. In 14 subjects 16 type C pulmonary nodules were histologically proved. Nine nodules were found to be benign lesions, while 7 nodules revealed malignant lung cancer: 5 cases of adenocarcinoma and 2 cases of adenosquamous carcinoma. We determined morphological characteristics of potentially malignant pulmonary nodules in 39 high-risk male smokers and proved lung cancer in 7 subjects.

    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.

    Pulmonary thromboendarterectomy is the treatment of choice in patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, specific medical treatment of pulmonary hypertension (PH) can be an alternative or play a complementary role to surgery. Thus, in patients unsuitable for surgery due to distal thrombotic obstruction, residual or persistent PH after surgery or very severe PH and a high-risk hemodynamic profile, medical treatment may improve their clinical course and the outcome of thromboendarterectomy. Patients with distal obstruction in the pulmonary tree and those with residual PH after surgery show clinical and hemodynamic deterioration due to progression of the pulmonary vascular disease in the smallcaliber arterioles. Conventional treatment with diuretics, anticoagulants and oxygen therapy has been demonstrated to have little effectiveness. In the last decade, numerous drugs have been developed for the treatment of PH: prostacyclin analogs, endothelin receptor antagonists, and phosphodiesterase-5 inhibitors acting principally in vascular remodelling of small-caliber arterioles. Although evidence of the effectiveness of these drugs in PH and the histological similarity of small-vessel vasculopathy in CTEPH to that of other forms of PH provide the main rationale for the use of these drugs in patients with CTEPH, the evidence from clinical trials is still limited.

    We assessed the impact of a multidisciplinary team care program on treatment outcomes in neuroblastoma patients. Newly diagnosed neuroblastoma patients received treatment under the Taiwan Pediatric Oncology Group (TPOG) N2002 protocol at the National Taiwan University Hospital beginning in 2002. A multidisciplinary team care approach that included nurse-led case management for patients treated under this protocol began in January 2010. Fifty-eight neuroblastoma patients, including 29 treated between 2002 and 2009 (Group 1) and 29 treated between 2010 and 2014 (Group 2), were enrolled in the study. The 5-year overall survival (OS) and event-free survival (EFS) rates for all 58 patients were 59% and 54.7%, respectively. Group 2 patients, who were treated after implementation of the multidisciplinary team care program, had better 3-year EFS (P = 0.046), but not OS (P = 0.16), rates than Group 1 patients. In a multivariate analysis, implementation of the multidisciplinary team approach was the only significant independent prognostic factor for neuroblastoma patients. In further subgroup analyses, the multidisciplinary team approach improved EFS, but not OS, in patients with stage 4 disease, those in the high-risk group, and those with non-MYCN amplified tumors. These data indicate a multidisciplinary team care approach improved survival outcomes in high-risk neuroblastoma patients. However, further investigation will be required to evaluate the long-term effects of this approach over longer follow-up periods.

    The results of treatment for 174 patients at high risk of local recurrence, referred for radiotherapy after conservative surgery for early breast cancer, are evaluated. Microscopic margin involvement, extensive carcinoma in situ, and vascular/lymphatic invasion were the main risk factors for local recurrence. Whole-breast irradiation (40 Gy in 15 fractions over 3 weeks) followed with a brachytherapy boost (Ir192 wire implant or PDR Ir192) of 25 Gy was applied. Median follow-up was 80 months. The actuarial 6-year overall survival rate was 91% and the within breast recurrence-free survival was 88%. The most common risk factor among those recurring within the breast was involved surgical margins (13 out of 17). Cosmesis was reported to be good or excellent in 79% of cases. In patients at high risk for local recurrence, tumour-bed boost with brachytherapy can provide satisfactory local control after limited surgery and external radiotherapy.

  9. High-risk plaque in patients with near normal coronary angiograms.

    2016-11-01

    The increased use of cardiac computed tomography angiography in the emergency room to triage patients who present with chest pain syndrome has led to the identification of individuals with coronary plaques with high-risk characteristics in the absence of significant stenoses. Anecdotal observations have suggested that the presence of coronary high-risk plaque results in an increased risk of acute coronary syndrome over time. This case presentation represents an example of this subgroup of patients. Intuitively, it would seem that high-dose statin therapy would be the treatment of choice, with percutaneous intervention reserved for the development of flow-limiting lesions; however, a prospective trial to determine outcomes to our knowledge has not been performed.

    Genomic instability induces an accumulation of genetic changes and may play a role in the pathogenesis of myelodysplastic syndromes (MDS). To clarify the possible association between genomic instability and clinical outcome in MDS patients, we compared telomere dynamics to the recently established International Prognostic Scoring System (IPSS) risk groups for MDS. We measured the terminal restriction fragments (TRFs) of 93 patients with MDS at the time of diagnosis, and telomerase activity was analyzed in 62 patients with MDS using the PCR-based telomeric repeat amplification protocol (TRAP) assay. A total of 53 of 93 MDS patients had TRFs within the age-matched normal range, and the remaining patients showed shortened TRFs (35 patients) or elongated TRFs (5 patients). MDS patients with shortened TRFs had a significantly low hemoglobin concentration (P = 0.04), a high percentage of marrow blasts (P = 0.02), and a high incidence of cytogenetic abnormalities (P < 0.05). The incidence of leukemic transformation was significantly high in patients with shortened TRF length (P < 0.05). In addition, patients with shortened TRF length were frequently seen in the IPSS high-risk group (P < 0.01). Most of the MDS patients had normal-to-low levels of telomerase activity, suggesting that changes in TRF length rather than telomerase activity may more accurately reflect the pathophysiology of MDS. MDS patients with shortened TRF length had a very poor prognosis (P < 0.01), suggesting that telomere dynamics may be linked to clinical outcome in MDS patients. Thus, an abnormal mechanism of telomere maintenance in subgroups of MDS patients may be an early indication of genomic instability. This study demonstrates that telomere stability is frequently impaired in a high-risk group of MDS patients and suggests that, in combination with the IPSS classification system, measurement of TRFs may be useful in the future to stratify MDS patients according to risk and manage the care of MDS

    Liberal versus restrictive red blood cell (RBC) transfusion triggers have been debated for years. This review illustrates the human body's physiologic response to acute anemia and summarizes the evidence from prospective randomized trials (RCTs) for restrictive use of RBC transfusions in high-risk patients. During progressive anemia, the human body maintains the oxygen delivery to the tissues by an increase in cardiac output and peripheral oxygen extraction. Seven RCTs with a total of 5,566 high-risk patients compared a restrictive hemoglobin (Hb) transfusion trigger (Hb < 70 or < 80 g/l) with a liberal Hb transfusion trigger (Hb < 90 or < 100 g/l). Unanimously these studies show non-inferiority, safety, and a significant reduction in RBC transfusions in the restrictive groups. In one RCT mortality was higher in the liberal Hb transfusion group, and in two additional RCTs mortality of subgroups or after risk adjustment was significantly higher in the liberal Hb transfusion trigger groups. Conclusion Strong RCT evidence suggests the safety of restrictive transfusion triggers. As a consequence, an Hb transfusion trigger of <70 g/l is recommended for high risk patients. PMID:26019706

    Objectives: to stratify the risk for obstructive sleep apnea in patients with acute myocardial infarction, treated at a public, tertiary, teaching hospital of the state of São Paulo, Brazil, and to identify related sociodemographic and clinical factors. Method: cross-sectional analytical study with 113 patients (mean age 59.57 years, 70.8% male). A specific questionnaire was used for the sociodemographic and clinical characterization and the Berlin Questionnaire for the stratification of the risk of obstructive sleep apnea syndrome. Results: the prevalence of high risk was 60.2% and the outcome of clinical worsening during hospitalization was more frequent among these patients. The factors related to high risk were body mass index over 30 kg/m2, arterial hypertension and waist circumference indicative of cardiovascular risk, while older age (60 years and over) constituted a protective factor. Conclusion: considering the high prevalence of obstructive sleep apnea and its relation to clinical worsening, it is suggested that nurses should monitor, in their clinical practice, people at high risk for this syndrome, guiding control measures of modifiable factors and aiming to prevent the associated complications, including worsening of cardiovascular diseases.

    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.

    Infants born with hypoplastic left heart syndrome or other lesions resulting in a single right ventricle face the highest risk of mortality among all forms of congenital heart disease. Before the modern era of surgical palliation, these conditions were universally lethal; recent refinements in surgical technique and perioperative management have translated into dramatic improvements in survival. Nonetheless, these infants remain at a high risk of morbidity and mortality, and an appreciation of single ventricle physiology is fundamental to the care of these high-risk patients. Herein, resuscitation and perioperative management of infants with hypoplastic left heart syndrome are reviewed. Basic neonatal and pediatric life support recommendations are summarized, and perioperative first-stage clinical management strategies are reviewed.

    Children undergoing intense cancer treatment frequently require total parenteral nutrition (TPN). Rarely, vitamins are removed due to hypersensitivity to the carrier vehicle in the formulation. We present the case of a 5-year-old patient with stage 4, high-risk neuroblastoma who developed altered mental status, ataxia, and tachycardia during consolidative autologous stem cell transplantation. Skin findings and brain MRI were consistent with thiamine (vitamin B1) deficiency and Wernicke encephalopathy. Vitamin B1 administration rapidly reversed all skin and neurologic symptoms. This case highlights the importance of close monitoring of micronutrients in pediatric patients receiving prolonged courses of chemotherapy and stem cell transplantation.

    Telomere length attrition has been demonstrated in schizophrenia but not in individuals in ultra high risk (UHR) for psychosis. The present study aimed to compare the leukocyte telomere length (TL) between patients at UHR for psychosis and healthy controls (HC). Twenty-two participants with UHR and 88 HC were enrolled in this study. Telomere lengths were determined using a multiplex qPCR assay. After adjustment for age, sex, ethnicity, and education, patients in UHR, compared with HC groups, had shorter telomere length (RR: 0.929, p=0.031). Shorter leukocyte telomere length in UHR could represent early signs of accelerated aging in this population.

    The global aging of population will lead a greater number of elderly patients to undergo surgical procedure in a near future. Concerning gastric cancer, the impact of lymphadenectomy on survival has been demonstrated in RCTs, and extended lymphadenectomy is now considered as gold standard of treatment in non-early tumors. However, the role of age as a prognostic factor and the benefit of extended surgery in elderly/high-risk patients are not clearly defined yet. From our revision of literature, it seems that surgery for gastric cancer may have a further tailorization, considering not only the stage of disease, but also patients’ age and comorbidities.

    In 56 patients aged from 58 to 82 years with the III and IV degrees of risk operated upon for malignant tumors of organs of the thoracic and abdominal organs Solcoseryl was included in the complex of anesthesia measures. It was given intravenously or as inhalation in dosage of 1000 mg. It was found that using Solcoseryl considerably reduced the amount of postoperative complications in high risk patients. It led to lower level of lipid peroxidation and activation of the antioxidant system and thus may be considered as an important component of therapy at the intra- and postoperative periods.

    Emergency cholecystectomy for acute cholecystitis (AC) is associated with high morbidity and mortality rates in elderly patients with significant comorbidities. The aim of this study was to evaluate percutaneous cholecystostomy for AC in elderly patients with various coexisting diseases. We retrospectively reviewed the records of 4311 patients with AC treated in Mackay Memorial Hospital between the years 2000 and 2015. The clinical course of AC was compared between nonelderly (age ≤70 years) and elderly patients (age>70 years). In total, 67 elderly patients and 32 nonelderly patients received percutaneous cholecystostomy. The rate of percutaneous cholecystostomy increased between the years 2011 and 2015 (from 2.5% to 12.2%) and this procedure was more common in the elderly group (p=0.009). In addition, the comorbidities of ischemic heart disease and chronic kidney disease were higher in elderly than in nonelderly patients (p=0.014 and p=0.015, respectively). The American Society of Anesthesiologists' classification was higher in the elderly patients (p=0.001). The overall survival-free rate of recurrent cholecystitis in patients who did not receive cholecystectomy was not significantly different in the two groups. When compared with emergent cholecystectomy in high-risk elderly patients, percutaneous cholecystostomy resulted in reduced hospital stay and morbidity (p=0.002 and p=0.013, respectively). Our results demonstrate that percutaneous cholecystostomy has become a common and early treatment for AC in high-risk elderly patients with ischemic heart disease or chronic kidney disease. Identifying such patients will possibly improve clinical outcomes, reduce hospital stay and morbidity, and facilitate delayed laparoscopic cholecystectomy.

    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

    Study Objective We sought to (1) define the high-risk elderly trauma patient based on prognostic differences associated with different injury patterns and (2) derive alternative field trauma triage guidelines that mesh with national field triage guidelines to improve identification of high-risk elderly patients. Methods This was a retrospective cohort study of injured adults ≥ 65 years transported by 94 EMS agencies to 122 hospitals in 7 regions from 1/1/2006 through 12/31/2008. We tracked current field triage practices by EMS, patient demographics, out-of-hospital physiology, procedures and mechanism of injury. Outcomes included Injury Severity Score ≥ 16 and specific anatomic patterns of serious injury using Abbreviated Injury Scale score ≥ 3 and surgical interventions. In-hospital mortality was used as a measure of prognosis for different injury patterns. Results 33,298 injured elderly patients were transported by EMS, including 4.5% with ISS ≥ 16, 4.8% with serious brain injury, 3.4% with serious chest injury, 1.6% with serious abdominal-pelvic injury and 29.2% with serious extremity injury. In-hospital mortality ranged from 18.7% (95% CI 16.7–20.7) for ISS ≥ 16 to 2.9% (95% CI 2.6–3.3) for serious extremity injury. The alternative triage guidelines (any positive criterion from the current guidelines, GCS ≤ 14 or abnormal vital signs) outperformed current field triage practices for identifying patients with ISS ≥ 16: sensitivity (92.1% [95% CI 89.6–94.1%] vs. 75.9% [95% CI 72.3–79.2%]), specificity (41.5% [95% CI 40.6–42.4%] vs. 77.8% [95% CI 77.1–78.5%]). Sensitivity decreased for individual injury patterns, but was higher than current triage practices. Conclusions High-risk elderly trauma patients can be defined by ISS ≥ 16 or specific non-extremity injury patterns. The field triage guidelines could be improved to better identify high-risk elderly trauma patients by EMS, with a reduction in triage specificity. PMID:26477345

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.

    High-risk surgery represents 12.5% of cases but contributes 80% of deaths in the elderly population. Reduction in morbidity and mortality by the use of intervention strategies could result in thousands of lives being saved and savings of up to £400m per annum in the UK. This has resulted in the drive towards goal-directed therapy and intraoperative flow optimization of high-risk surgical patients being advocated by authorities such as the National Institute of Health and Care Excellence and the Association of Anaesthetists of Great Britain and Ireland.Conventional intraoperative monitoring gives little insight into the profound physiological changes occurring as a result of anesthesia and surgery. The build-up of an oxygen debt is associated with a poor outcome and strategies have been developed in the postoperative period to improve outcomes by repayment of this debt. New monitoring technologies such as minimally invasive cardiac output, depth of anesthesia and cerebral oximetry can minimize oxygen debt build-up. This has the potential to reduce complications and lessen the need for postoperative optimization in high-dependency areas.Flow monitoring has thus emerged as essential during intraoperative monitoring in high-risk surgery. However, evidence suggests that current optimization strategies of deliberately increasing flow to meet predefined targets may not reduce mortality.Could the addition of depth of anesthesia and cerebral and tissue oximetry monitoring produce a further improvement in outcomes?Retrospective studies indicate a combination of excessive depth of anesthesia hypotension and low anesthesia requirement results in increased mortality and length of hospital stay.Near infrared technology allows assessment and maintenance of cerebral and tissue oxygenation, a strategy, which has been associated with improved outcomes. The suggestion that the brain is an index organ for tissue oxygenation, especially in the elderly, indicates a role for this

    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

    PurposeTo retrospectively evaluate the effectiveness of computed tomography-guided percutaneous microwave ablation (MWA) and cementoplasty in patients with painful bone metastases at high risk of fracture.Materials and MethodsThirty-five patients with 37 metastatic bone lesions underwent computed tomography-guided MWA combined with cementoplasty (polymethylmethacrylate injection). Vertebrae, femur, and acetabulum were the intervention sites and the primary end point was pain relief. Pain severity was estimated by visual analog scale (VAS) before treatment; 1 week post-treatment; and 1, 6, and 12 months post-treatment. Functional outcome was assessed by improved patient walking ability. Radiological evaluation was performed at baseline and 3 and 12 months post-procedure.ResultsIn all patients, pain reduction occurred from the first week after treatment. The mean reduction in the VAS score was 84, 90, 90 % at week 1, month 1, and month 6, respectively. Improved walking ability occurred in 100 and 98 % of cases at the 1- and 6-month functional outcome evaluations, respectively. At the 1-year evaluation, 25 patients were alive, and 10 patients (28 %) had died because of widespread disease. The mean reduction in the VAS score and improvement in surviving patients’ walking ability were 90 and 100 %, respectively. No patients showed evidence of local tumor recurrence or progression and pathological fracture in the treated sites.ConclusionOur results suggest that MWA combined with osteoplasty is safe and effective when treating painful bone metastases at high risk of fracture. The number of surviving patients at the 1-year evaluation confirms the need for an effective and long-lasting treatment.

    The burden related to the ever-increasing dementia prevalence in older individuals, imposes the implementation of prevention strategies. It is now known that brain lesions related to Alzheimer's disease precede the onset of the first symptoms. Consequently, prevention strategies should be implemented early, before clinically overt dementia. Blood and spine fluid tests, electroencephalogram, brain magnetic resonance and brain nuclear imaging should help physicians to better target "high-risk" patients prone to benefit from such strategies, already in a preclinical disease stage. Since no efficient pharmacological treatments exist for the time being, lifestyle factors such as nutritionand physical exercise are the cornerstones for dementia prevention.

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

    The incidence of local recurrence after mastectomy can be reduced by chest wall radiotherapy. However, only a minority of patients are at substantial risk. No UK national guidelines exist for the use of mastectomy flap radiotherapy. This study evaluated a protocol, whereby only high-risk patients were treated with post-mastectomy flap radiotherapy; identified histologically by grade, vascular invasion and nodal status. All women treated by simple mastectomy for invasive breast cancer at the Nottingham Breast Unit from January 1993 to December 1995 were studied (n=292). Postoperative flap radiotherapy was given to 147 high-risk women (50.3%). Median follow-up was 76 months. Overall, 12 women (4.1%) developed a chest wall recurrence; six were single spot recurrences and the remaining six were either multiple spot (n=3) or field change (field change dermal invasion, n=3). The chest wall recurrence rate was 2.7% in those treated with radiotherapy. A low rate of local recurrence has been achieved with selective use of mastectomy flap radiotherapy.

    BACKGROUND Basic research suggests that rapid increases in circulating inflammatory and hemostatic blood markers may trigger or indicate impending plaque rupture and coronary thrombosis, resulting in acute ischemic heart disease (IHD) events. However, these associations are not established in humans. METHODS AND RESULTS The Biomarker Risk Assessment in Vulnerable Outpatients (BRAVO) Study will determine whether levels of inflammatory and hemostatic biomarkers rapidly increase during the weeks prior to an acute IHD event in people with lower extremity peripheral artery disease (PAD). The BRAVO Study will determine whether biomarker levels measured immediately prior to an IHD event are higher than levels not preceding an IHD event; whether participants who experience an IHD event (cases) have higher biomarker levels immediately prior to the event and higher biomarker levels at each time point leading up to the IHD event than participants without an IHD event (controls); and whether case participants have greater increases in biomarkers during the months leading up to the event than controls. BRAVO enrolled 595 patients with PAD, a population at high risk for acute IHD events. After a baseline visit, participants returned every two months for blood collection, underwent an electrocardiogram to identify new silent myocardial infarctions, and were queried about new hospitalizations since their prior study visit. Mortality data were also collected. Participants were followed prospectively for up to three years. CONCLUSIONS BRAVO results will provide important information about the pathophysiology of IHD events and may lead to improved therapies for preventing IHD events in high-risk patients. PMID:24721480

    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

  13. Preoperative intra-aortic balloon pumping in high-risk cardiac surgery patients.

    PubMed

    Moon, Chooza

    2012-01-01

    Intra-aortic balloon pumping increases myocardial oxygen supply and decreases myocardial oxygen demand by inflation and deflation of the balloon. This leads to increased perfusion of the coronary arteries during diastole. This technology has been used for critically ill cardiac patients for more than 30 years. The literature suggests that preoperative use of an intra-aortic balloon pump can be effective in high-risk coronary artery bypass grafting patients. Preoperative benefits of this technology may yield positive outcomes in terms of hemodynamic effect, decreased length of stay in both the intensive care unit and the hospital, and the reduction of complications. However, the intra-aortic balloon pump must be used with a profound understanding of proper mechanism and function, monitoring, and observation for potential complications. This requires excellent critical care nursing management.

    Essential thrombocythemia is a rare type of myeloproliferative disorder. Cerebral, myocardial, and peripheral thrombosis are all frequent complications of the disease. A 71-year-old man presented with severe coronary artery disease, associated with cerebral vascular ischemic changes and erythromelalgia. His platelet count was 1,486 ×103/μL. The patient underwent successful myocardial revascularization by means of an off-pump technique after his platelet count had been reduced by hydroxycarbamide administration. We conclude that the use of off-pump cardiopulmonary bypass in high-risk patients with essential thrombocythemia is safe. Reducing platelet count via the administration of hydroxycarbamide and the careful balancing of antiplatelets and anticoagulants is crucial in determining the outcome of surgery. PMID:25425991

    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.

  16. Patient-prosthesis mismatch: surgical aortic valve replacement versus transcatheter aortic valve replacement in high risk patients with aortic stenosis

    PubMed Central

    Kron, Irving L.

    2016-01-01

    Patient prosthesis mismatch (PPM) can occur when a prosthetic aortic valve has an effective orifice area (EOA) less than that of a native valve. A recent study by Zorn and colleagues evaluated the incidence and significance of PPM in high risk patients with severe aortic stenosis who were randomized to transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). TAVR is associated with decreased incidence of severe PPM compared to traditional SAVR valves. Severe PPM increases risk for death at 1 year postoperatively in high risk patients. The increased incidence of PPM is largely due to differences in valve design and should encourage development of newer SAVR valves to reduce risk for PPM. In addition more vigorous approaches to root enlargement in small annulus should be performed with SAVR to prevent PPM. PMID:27867654

    Pulmonary rehabilitation is considered a key management strategy for chronic obstructive pulmonary disease (COPD), but its effectiveness is undermined by poor patient uptake and completion. The aim of this review was to identify, select and synthesise the available evidence on interventions for improving uptake and completion of pulmonary rehabilitation in COPD. Electronic databases and trial registers were searched for randomised trials evaluating the effect of an intervention compared with a concurrent control group on patient uptake and completion. The primary outcomes were the number of participants who attended a baseline assessment and at least one session of pulmonary rehabilitation (uptake), and the number of participants who received a discharge assessment (completion). Only one quasi-randomised study (n=115) (of 2468 records identified) met the review inclusion criteria and was assessed as having a high risk of bias. The point estimate of effect did, however, indicate greater programme completion and attendance rates in participants allocated to pulmonary rehabilitation plus a tablet computer (enabled with support for exercise training) compared with controls (pulmonary rehabilitation only). There is insufficient evidence to guide clinical practice on interventions for improving patient uptake and completion of pulmonary rehabilitation in COPD. Despite increasing awareness of patient barriers to pulmonary rehabilitation, our review highlights the existing under-appreciation of interventional trials in this area. This knowledge gap should be viewed as an area of research priority due to its likely impact in undermining wider implementation of pulmonary rehabilitation and restricting patient access to a treatment considered the cornerstone of COPD.

    We studied the frequency with which unexplained oral candidiasis led to unequivocal acquired immunodeficiency syndrome (AIDS) in patients at risk. Twenty-two previously healthy adults with unexplained oral candidiasis, of whom the 19 tested had a reversed T4/T8 ratio and 20 had generalized lymphadenopathy, were compared with 20 similar patients with a reversed T4/T8 ratio and generalized lymphadenopathy who did not have oral candidiasis. All were intravenous-drug abusers, homosexual or bisexual men, or both. Thirteen of the 22 patients with oral candidiasis (59 per cent) acquired a major opportunistic infection or Kaposi's sarcoma at a median of three months (range, 1 to 23) as compared with none of 20 patients with generalized lymphadenopathy and immunodeficiency but without candidiasis who were followed for a median of 12 months (range, 5 to 21) (P less than 0.001). AIDS developed in 12 of 15 patients with candidiasis and T4/T8 ratios less than or equal to 0.51, as compared with none of four with ratios equal to or greater than 0.60 (P less than 0.01). We conclude that in patients at high risk for AIDS, the presence of unexplained oral candidiasis predicts the development of serious opportunistic infections more than 50 per cent of the time. Whether the remainder will have AIDS is not yet known.

    Results are presented from our single-institutional experience with thoracic endovascular aortic repair to confirm that it is safe in patients with significant comorbidities. A retrospective review of all patients undergoing endovascular or open thoracic aortic repair at our institution since 2002 was performed. Main outcome measures included clinical presentation, demographics, preoperative risk factors, operative details, and clinical outcomes. The endovascular group included 37 patients (22 males), whereas the open group included 19 patients (eight males). Eight patients per group were treated emergently for trauma or rupture (22% and 42%, respectively; p=0.11). Endovascular patients were significantly older with more comorbid conditions (p<0.05). However, the overall perioperative complication rate was similar in the two groups (32.4% and 31.6%, respectively). Postoperative renal failure occurred only in four open patients (21.1% vs. 0%, p < 0.05). Operative time, ventilator days, and total length of stay were also greater for open patients (p<0.05). There was one death in the endovascular group and three in the open group (2.7% and 15.8%, respectively; p=0.07). Endovascular patients had shorter operative time and length of stay, fewer ventilator days and intensive care unit days, and fewer transfusions. Although the endovascular patients were significantly older with more comorbidities, the complication rate was similar to the open group. Also, there was a trend toward lower mortality in the endovascular group (p=0.07). Endovascular repair is the procedure of choice for treating the descending thoracic aorta in high-risk patients even in the emergent setting.

    Shunt infection is a morbid complication of cerebrospinal fluid (CSF) shunting. The catheters with a hydrophilic surface may impede bacterial adherence and thereby reduce catheter-related CSF infection.A retrospective study compared the occurrence of CSF infection related to use of either standard silastic catheters or hydrogel-coated ventricular catheters (Bioglide, Medtronic). The enrolment was available to neurosurgery patients undergoing shunt surgery from October 2012 to 2015 in two centers. The follow-up period was more than months.A total of 78 patients were included in the study. In 33 patients 35-cm hydrogel-coated ventricular peritoneum shunts (VPS) were used, and in remaining 45 patients 35-cm standard silastic VPS catheters were used. Infection occurred in 14 (17.9%) patients, including definite VPS-related CSF infection in 6 patients (7.7%) and probable infection in remaining 8 patients (10.3%). There was a significant difference found in patients with total infection between the two groups [RR (95% CI); 0.200 (0.050-0.803), P = 0.014]. Analysis of Kaplan-Meier curve estimates indicated significant statistical difference between the two catheter types in duration (log rank = 4.204, P < 0.05). Significant statistical differences were also found in the subgroups including previous CSF infection within 1 month (log rank = 4.391, P = 0.04), conversion of external ventricular drains to shunt (Log Rank = 4.520, P = 0.03), and hospital stay >1 month (log rank = 5.252, P = 0.02). There was no difference found between the two groups of the patients with other infections within 1 month. The follow-up period was of 36 months.The hydrogel-coated catheter is a safe and related to lower infection rates for high-risk patients who underwent shunt surgery.

    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.

    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

    Background The Centers for Medicare and Medicaid Services (CMS) have established guidelines that outline patients who are considered “high risk” for complications following CEA for which CAS may provide benefit. The validity of these high risk criteria are yet unproven. In this study, we stratified patients who underwent either CAS or CEA by CMS high risk criteria and symptom status, and examined their 30-day outcomes. Methods A non-randomized, retrospective cohort study was performed by chart review of all patients undergoing CEA or CAS from January 1, 2005 to December 31, 2010 at our institution. Demographic data, as well as data pertaining to the presence or absence of high risk factors were collected. Patients were stratified using symptom status and high risk status as variables and 30-day adverse events (stroke, death, and/or myocardial infarction (MI)) were compared. Results 271 patients underwent CAS with 30-day complication rates of stroke (3.0%), death (1.1%), MI (1.5%), stroke/death (3.7%), and stroke/death/MI (5.2%). 830 patients underwent CEA with 30-day complication rates of stroke (2.0%), death (0.1%), MI (0.6%), stroke/death (1.9%), and stroke/death/MI (2.7%). Among symptomatic patients, physiologic high risk status was associated with increased stroke/death (6/42, 14.3% vs. 2/74, 2.7%, P<0.01), and anatomic high risk status was associated with a trend towards increased stroke/death (5/31, 16.1% vs. 0/20, 0.0%, P=0.14) in patients who underwent CAS compared to CEA. Analysis of asymptomatic patients showed no differences among the two groups overall, except for a trend towards higher rate of MI following CAS compared to CEA (3/71, 4.2% vs. 0/108, 0.0%, P=.06) in those who were physiologically high risk. Among symptomatic patients who underwent CAS, patients with physiologic and anatomic high risk factors had a higher rate of stroke/death compared to non-high risk patients (6/42, 14.3% vs. 0/24, 0.0% and 5/31, 16.1% vs. 0/24, 0.0%, respectively

    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

    Partial calcanectomy (PC) is an established limb salvage procedure for treatment of deep heel ulceration with concomitant calcaneal osteomyelitis. The purpose of this study is to determine if a relationship exists between the amount of calcaneus removed during PC and the resulting lower extremity function and limb salvage outcomes. Consecutive PC patients were retrospectively divided into two cohorts defined by the amount of calcaneus resected before wound closure: patients in cohort 1 retained = 50% of calcaneus, while patients in cohort 2 underwent resection of >50% of the calcaneus. The Lower Extremity Function Scale (LEFS) was used to assess postoperative lower extremity function. The average amount of calcaneus resected was 13% ± 9.2 (1–39%) and 74% ± 19.5 (51–100) in cohorts 1 and 2, respectively (P < 0.0001). Below knee amputation was performed in 7 (28%) and 5 (29%) of subjects in cohorts 1 and 2, respectively (P = 1.0). The average LEFS score was 33.9 ± 15.0 for subjects in cohort 1 and 36.2 ± 19.9 for the subjects cohort 2 (P = 0.8257) which correlates to “moderate to quite a bit of difficulty.” Our study suggests that regardless of the amount of calcaneus resected, PC provides a viable treatment option for high-risk patients with calcaneal osteomyelitis.

    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

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

    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.

    Over the past decades, there has been considerable progress in the field of less invasive haemodynamic monitoring technologies. Substantial evidence has accumulated, which supports the continuous measurement and optimization of flow-based variables such as stroke volume, that is, cardiac output, in order to prevent occult hypoperfusion and consequently to improve patients' outcome in the perioperative setting. However, there is a striking gap between the developments in haemodynamic monitoring and the increasing evidence to implement defined treatment protocols based on the measured variables, and daily clinical routine. Recent trials have shown that perioperative morbidity and mortality is higher than anticipated. This emphasizes the need for the anaesthesia community to address this issue and promotes the implementation of proven concepts into clinical practice in order to improve patients' outcome, especially in high-risk patients. The advances in minimally invasive and non-invasive monitoring techniques can be seen as a driving force in this respect, as the degree of invasiveness of any monitoring tool determines the frequency of its application, especially in the operating room (OR). From this point of view, we are very confident that some of these minimally invasive and non-invasive haemodynamic monitoring technologies will become an inherent part of our monitoring armamentarium in the OR and in the intensive care unit (ICU).

  13. Should elective surgery for chronic pancreatitis be performed in high-risk patients?

    As morbidity and mortality rates for pancreatic surgery have improved over the past decades, patients with major medical comorbidities have been considered for operative treatment. The influence of poor health status on operative morbidity in patients with chronic pancreatitis is evaluated in this study. The records of 313 consecutive patients who underwent pancreaticoduodenectomy (n = 78), distal pancreatectomy (n = 83), or lateral pancreaticojejunostomy (n = 152) for chronic pancreatitis were retrospectively reviewed and analyzed. Patients' risk for adverse outcome resulting from overall health status was audited using age, comorbidities, and Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) physiological score. Univariate analysis showed that patient's age did not contribute to change in morbidity (odds ratio [OR] = 1.01, P = 0.59). The presence of cardiac disease but not other comorbidities increased adverse outcome affected the need for intensive care unit stay and length of hospital stay (morbidity: 29% vs. 51%, OR = 2.6, P = 0.003). POSSUM physiological score was associated with an increase in morbidity and mortality (morbidity: OR = 1.16, P = 0.001; mortality: OR = 1.49, P = 0.001), in particular intraabdominal abscesses. Multivariate analysis showed that the only variable independently correlating with perioperative complications was POSSUM physiological score. Single comorbidities do not independently influence outcome after operations for chronic pancreatitis. A combination of several comorbidities is associated with an increase in postoperative infectious morbidity and mortality. High-risk patients should not be excluded from operative treatment, but need to be closely selected on a case-by-case basis.

    Primary central nervous system lymphoma (PCNSL) is a rare disorder that, in 95% of cases, represents diffuse large B-cell lymphoma. As such, making an accurate diagnosis is important. At present, stereotactic-guided biopsy is a recognized method of choice for tissue analysis. However, the diagnostic work-up for high-risk patients is determined by their performance status. Here, we report a case of PCNSL in a high-risk patient, for whom diagnosis was established by cerebrospinal fluid cytology and flow cytometry, which significantly shortened a diagnostic work-up period and allowed for the immediate treatment of the patient.

    The relevance of blood-based assays to monitor minimal residual disease (MRD) in non-metastatic prostate cancer (PCa) remains unclear. Proving that clinically relevant circulating tumor cells (CTCs) can be detected with available technologies could address this. This study aimed to improve CTC detection in non-metastatic PCa patients by combining three independent CTC assays: the CellSearch system, an in vivo CellCollector and the EPISPOT. Peripheral blood samples from high-risk PCa patients were screened for CTCs before and three months after radical prostatectomy (RP). Combining the results of both time points, CTCs were detected in 37%, 54.9% and 58.7% of patients using CellSearch, CellCollector and EPISPOT, respectively. The cumulative positivity rate of the three CTC assays was 81.3% (87/107) with 21.5% (23/107) of patients harboring ≥5 CTCs/7.5 ml blood. Matched pair analysis of 30 blood samples taken before and after surgery indicated a significant decrease in CTCs captured by the CellCollector from 66% before RP to 34% after therapy (p = 0.031). CTC detection by EPISPOT before RP significantly correlated with PSA serum values (p < 0.0001) and clinical tumor stage (p = 0.04), while the other assays showed no significant correlations. In conclusion, CTC-based liquid biopsies have the potential to monitor MRD in patients with non-metastatic prostate cancer. PMID:28000772

    The association between colorectal cancer and human papillomavirus (HPV) infection is still unproven. The aim of this study was to investigate the presence of high-risk HPV (HR-HPV) DNA in colorectal tissues from Cuban patients. A total of 63 colorectal formalin-fixed paraffin-embedded tissues were studied (24 adenocarcinoma, 18 adenoma, and 21 colorectal tissues classified as benign colitis). DNA from colorectal samples was analysed by quantitative real-time polymerase chain reaction to detect the most clinically relevant high HR-HPV types (HPV-16, -18, -31, -33, -45, -52, and -58). Associations between histologic findings and other risk factors were also analysed. Overall, HPV DNA was detected in 23.8% (15/63) of the samples studied. Viral infections were detected in 41.7% of adenocarcinoma (10/24) and 27.7% of adenoma cases (5/18). HPV DNA was not found in any of the negative cases. An association between histological diagnosis of adenocarcinoma and HPV infection was observed (odd ratio = 4.85, 95% confidence interval = 1.40-16.80, p = 0.009). The only genotypes identified were HPV 16 and 33. Viral loads were higher in adenocarcinoma, and these cases were associated with HPV 16. This study provides molecular evidence of HR-HPV infection in colorectal adenocarcinoma tissues from Cuban patients. PMID:27812599

    Hemopump is a ventricular assist device which is aimed at improving the management of high- risk patients for PTCA. The aim of the study was to access coronary blood flow velocity during hemopump. The hemopump was inserted percutaneously into the femoral artery. Coronary blood flow was measured with a 12 MHz Doppler-tipped guidewire proximal and distal to the stenosis before, during and after PTCA. Coronary vascular reserve was assessed by intracoronary 12 mg bolus injection of Papaverine. Collateral flow was assessed during balloon occlusion by inverted velocity signals below baseline. Eight patients aged 59 +/- 11 yrs, with unstable angina, a last patent vessel and/or major left ventricular dysfunction (EF < 0.20) had hemopump during PTCA of stenosis (86 +/- 14%) of the LAD (n equals 4) or the LCX (n equals 4). Collateral flow was slightly increased (+25 +/- 18%) by the Hemopump. Hemopump did not strongly affect coronary flow velocity, did not significantly increase collateral flow and increased slightly coronary vascular reserve.

    Objective Cholecystolithiasis is a common disease in the elderly patient. The routine therapy is open or laparoscopic cholecystectomy. In the previous study, we designed a minimally invasive cholecystolithotomy based on percutaneous cholecystostomy combined with a choledochoscope (PCCLC) under local anesthesia. Methods To investigate the effect of PCCLC on the gallbladder contractility function, PCCLC and laparoscope combined with a choledochoscope were compared in this study. Results The preoperational age and American Society of Anesthesiologists (ASA) scores, as well as postoperational lithotrity rate and common biliary duct stone rate in the PCCLC group, were significantly higher than the choledochoscope group. However, the pre- and postoperational gallbladder ejection fraction was not significantly different. Univariable and multivariable logistic regression analyses indicated that the preoperational thickness of gallbladder wall (odds ratio [OR]: 0.540; 95% confidence interval [CI]: 0.317–0.920; P=0.023) and lithotrity (OR: 0.150; 95% CI: 0.023–0.965; P=0.046) were risk factors for postoperational gallbladder ejection fraction. The area under receiver operating characteristics curve was 0.714 (P=0.016; 95% CI: 0.553–0.854). Conclusion PCCLC strategy should be carried out cautiously. First, restricted by the diameter of the drainage tube, the PCCLC should be used only for small gallstones in high-risk surgical patients. Second, the usage of lithotrity should be strictly limited to avoid undermining the gallbladder contractility and increasing the risk of secondary common bile duct stones. PMID:28138229

    Total hip replacement (THR) and total knee arthroplasty (TKA) carry a high risk of postoperative venous thromboembolism (VTE); therefore, anticoagulation prophylaxis is recommended in these patients. Unfortunately, there are no guidelines about VTE prophylaxis in patients with hemophilia who underwent these high-risk surgeries. To determine whether these patients have high risk of VTE, we conducted a retrospective study on patients with hemophilia who underwent elective THR/TKA at our institute from 2004 to 2012. Postoperatively, we collected information on duration and method of factor VIII/IX infusion, VTE-prophylaxis, and complications. There were 23 patients with hemophilia, 18 (78%) with hemophilia A and 5 (22%) with hemophilia B, who underwent high-risk surgeries (39% THR and 61% TKA). The VTE prophylaxis included sequential compression device, 12 (52%), and prophylactic enoxaparin, 1 (4%). Ten (43%) patients did not receive VTE prophylaxis. At 1-year follow-up, we did not find any evidence of clinical VTE in our patients. Better risk stratification is needed to identify patients who would benefit from pharmacological prophylaxis.

    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.

    AIM: To evaluate the usefulness and safety of argon plasma coagulation (APC) for superficial esophageal squamous-cell carcinoma (SESC) in high-risk patients. METHODS: We studied 17 patients (15 men and 2 women, 21 lesions) with SESC in whom endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), and open surgery were contraindicated from March 1999 through February 2009. None of the patients could tolerate prolonged EMR/ESD or open surgery because of severe concomitant disease (e.g., liver cirrhosis, cerebral infarction, or ischemic heart disease) or scar formation after EMR/ESD and chemoradiotherapy. After conventional endoscopy, an iodine stain was sprayed on the esophageal mucosa to determine the lesion margins. The lesion was then ablated by APC. We retrospectively studied the treatment time, number of APC sessions per site, complications, presence or absence of recurrence, and time to recurrence. RESULTS: The median duration of follow-up was 36 mo (range: 6-120 mo). All of the tumors were macroscopically classified as superficial and slightly depressed type (0-IIc). The preoperative depth of invasion was clinical T1a (mucosal cancer) for 19 lesions and clinical T1b (submucosal cancer) for 2. The median treatment time was 15 min (range: 10-36 min). The median number of treatment sessions per site was 2 (range: 1-4). The median hospital stay was 14 d (range: 5-68 d). Among the 17 patients (21 lesions), 2 (9.5%) had recurrence and underwent additional APC with no subsequent evidence of recurrence. There were no treatment-related complications, such as bleeding or perforation. CONCLUSION: APC is considered to be safe and effective for the management of SESC that cannot be resected endoscopically because of underlying disease, as well as for the control of recurrence after EMR and local recurrence after chemoradiotherapy.

    Background This study assessed patient-reported alcohol treatment offers by healthcare providers following routine annual screening for alcohol use in primary care. Methods A telephone interview within 30 days of the annual screen assessed demographics, alcohol and other drug use, mental health symptoms, and offers of formal treatment for alcohol by a VA healthcare provider. We included male patients (n = 349) at high-risk for an alcohol use disorder (AUD) who had not received alcohol treatment in the past three months. We assessed self-reported receipt of any offers of formal treatment for alcohol, and associations of offer of formal treatment for alcohol with demographic and clinical variables. Results 145 (41.5%) patients reported an offer of at least one type of formal treatment for alcohol. More severe alcohol misuse (OR 1.07, 95% CI 1.03 to 1.11) and younger age (OR 0.97, 95% CI 0.95 to 0.99) were associated with reporting an offer of formal treatment. Discussion Most primary care patients at high-risk for an AUD were not offered treatment following an annual screening. Our results highlight the importance of training primary care providers in what constitutes appropriate medical treatment for this population and the most effective ways of making a treatment offer.

    During surgery and childbirth, patients with hereditary antithrombin (AT) deficiency are at high risk for thrombosis, and heparin prophylaxis may not be sufficiently efficacious. In these patients, exogenous AT may be used in association with heparin. A recombinant human AT (generic name: antithrombin alfa) has been developed. This multi-center study assessed the efficacy and safety of prophylactic intravenous administration of antithrombin alfa to hereditary AT deficient patients in high risk situations, including elective surgery, childbirth, or cesarean section. Antithrombin alfa was administered prior to and during the high risk period for restoration and maintenance of AT activity at 100% of normal. Heparin, low-molecular-weight heparin, and/or vitamin K antagonists were used according to standard of care. The primary efficacy endpoint was the incidence of acute deep vein thrombosis (DVT) from baseline up to day 30 post dosing as assessed by independent central review of duplex ultrasonograms and/or venograms. Safety was assessed based on adverse events (AEs) and laboratory evaluations. Five surgical and nine obstetrical hereditary AT deficiency patients received antithrombin alfa for a mean period of seven days. No clinically overt DVT occurred. Central review of ultrasonograms identified signs of acute DVT in two out of 13 evaluable patients. No antithrombin alfa-related AEs were reported. No patient developed anti-antithrombin alfa antibodies. In conclusion, this study suggests that antithrombin alfa is a safe and effective alternative to human plasma-derived AT for treating hereditary AT deficiency patients at high risk for thromboembolic events.

    PubMed

    Béchade, Dominique

    2011-03-01

    Screening high-risk individuals with imaging tests, such endoscopic ultrasound and computed tomography, can lead to the detection and treatment of predominantly asymptomatic premalignant lesions. These pancreatic lesions consist of resectable, mostly branch-type non invasive intraductal papillary mucinous neoplasms. Endoscopic ultrasound features of chronic pancreatitis are highly prevalent in high-risk individuals and these directly correlate with multifocal lobulocentric parenchymal atrophy due to pancreatic intraepithelial neoplasia. Long-term, multi-prospective studies are needed to determine if screening for early pancreatic adenocarcinoma and timely intervention results in decreased pancreatic cancer incidence and mortality in high-risk individuals.

    High-risk low-volume therapies are those therapies that are practiced infrequently and yet carry an increased risk to patients because of their complexity. Staff nurses are required to competently manage these therapies to treat patients' unique needs and optimize outcomes; however, maintaining competence is challenging. This article describes implementation of Just-in-Time Training, which requires validation of minimum competency of bedside nurses managing high-risk low-volume therapies through direct observation of a return-demonstration competency checklist.

    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

    Imiquimod is a synthetic Toll-like receptor 7 (TLR7) agonist approved for the topical treatment of actinic keratoses, superficial basal cell carcinoma, and genital warts. Imiquimod leads to an 80–100% cure rate of lentigo maligna, but studies of invasive melanoma are lacking. We conducted a pilot study to characterize the local, regional, and systemic immune responses induced by imiquimod in patients with high-risk melanoma. After treatment of the primary melanoma biopsy site with placebo or imiquimod cream, we measured immune responses in the treated skin, sentinel lymph nodes (SLN), and peripheral blood. Treatment of primary melanomas with 5% imiquimod cream was associated with an increase in both CD4+ and CD8+ T cells in the skin, and CD4+ T cells in the SLN. Most of the CD8+ T cells in the skin were CD25 negative. We could not detect any increases in CD8+ T cells specifically recognizing HLA-A*0201-restricted melanoma epitopes in the peripheral blood. The findings from this small pilot study demonstrate that topical imiquimod treatment results in enhanced local and regional T cell numbers in both the skin and SLN. Further research into TLR7 immunomodulating pathways as a basis for effective immunotherapy against melanoma in conjunction with surgery is warranted. PMID:21850019

    This study was designed to analyze the outcomes of chemotherapy for high-risk gestational trophoblastic neoplasia (GTN) with EMA-CO regimen as primary and secondary protocol in China. Fifty-four patients with high-risk GTN received 292 EMA/CO treatment cycles between 1996 and 2005. Forty-five patients were primarily treated with EMA-CO, and nine were secondarily treated after failure to other combination chemotherapy. Adjuvant surgery and radiotherapy were used in the selected patients. Response, survival and related risk factors, as well as chemotherapy complications, were retrospectively analyzed. Thirty-five of forty-five patients (77.8%) receiving EMA-CO as first-line treatment achieved complete remission, and 77.8% (7/9) as secondary treatment. The overall survival rate was 87.0% in all high-risk GTN patients, with 93.3% (42/45) as primary therapy and 55.6% (5/9) as secondary therapy. The survival rates were significantly different between two groups (chi(2)= 6.434, P =0.011). Univariate analysis showed that the metastatic site and the number of metastatic organs were significant risk factors, but binomial distribution logistic regression analysis revealed that only the number of metastatic organs was an independent risk factor for the survival rate. No life-threatening toxicity and secondary malignancy were found. EMA-EP regimen was used for ten patients who were resistant to EMA-CO and three who relapsed after EMA-CO. Of those, 11 patients (84.6%) achieved complete remission. We conclude that EMA-CO regimen is an effective and safe primary therapy for high-risk GTN, but not an appropriate second-line protocol. The number of metastatic organs is an independent prognostic factor for the patient with high-risk GTN. EMA-EP regimen is a highly effective salvage therapy for those failing to EMA-CO.

    Patients with clinically isolated syndrome (CIS), unlike those with multiple sclerosis (MS), have a selective cognitive impairment which is not consistently related to structural brain changes. Our objective was to characterize a profile of cognitive impairment and its association with structural brain changes in patients with CIS who are at high risk of developing MS. Patients with CIS at high risk for MS on interferon-beta (n = 51) and age-, gender-, and education-matched controls (n = 44) underwent comprehensive neuropsychological testing and MRI brain scan with voxel-based morphometry. The CIS group had lower cognitive performance in verbal and nonverbal memory, information processing speed/attention/working memory, and executive and visuo-spatial functions compared to controls (p ≤ 0.040). Lower cognitive performance was present in 18-37 and 14-26% of patients with CIS at high risk for MS depending on the criteria used. Brain volume was reduced predominantly in fronto-temporal regions and the thalamus in the CIS group (p ≤ 0.019). Cognitive performance was not associated with structural brain changes except for the association between worse visuo-spatial performance and lower white matter volume in the CIS group (β = 0.29; p = 0.042). Our results indicated that patients with CIS at high risk for MS may have a pattern of lower cognitive performance and regional brain atrophy similar to that found in patients with MS. Lower cognitive performance may be present in up to one-third of patients with CIS at high risk for MS, but, unlike patients with MS, variability in their cognitive performance may lead to a lack of consistent associations with structural brain changes.

    In a setting where potable water is contaminated with Legionella pneumophila serogroup 1, we performed two case control studies. The first case control study consisted of 17 cases of nosocomial Legionnaires' disease (LD) and 33 control (the patients who were admitted to the ward where the case was admitted immediately before and after the case) subjects. Cases had a higher mortality rate 65% vs 12% (P less than 0.004); were more likely to have received assisted ventilation (P less than 0.00001); to have nasogastric tubes (P less than 0.0004) and to be receiving corticosteroids or other immunosuppressive therapy (P less than 0.0001). Based on the results of this study, sterile water was used to flush nasogastric tubes and to dilute nasogastric feeds. Only 3 cases of nosocomial LD occurred during the next year compared with 12 the previous year (P less than 0.0001). Nine cases subsequently occurred and formed the basis for the second case-control study. Eighteen control subjects were those patients admitted to the same unit where the case developed LD, immediately before and after the case. The mortality rate for the cases was 89% vs 6% for controls (P less than 0.00003). The only other significant difference was that cases were more likely to be receiving corticosteroids or other immunosuppressive therapy 89% vs 39% (less than 0.01). We hypothesized that microaspiration of contaminated potable water by immunocompromised patients was a risk factor for nosocomial Legionnaires' disease. From 17 March 1989 onwards such patients were given only sterile potable water. Only two cases of nosocomial LD occurred from June 1989 to September 1990 and both occurred on units where the sterile water policy was not in effect. We conclude that aspiration of contaminated potable water is a possible route for acquisition of nosocomial LD in our hospital and that provision of sterile potable water to high risk patients (those who are receiving corticosteroids or other immunosuppressive

    Pulmonary hypertension is a potentially lethal condition that may be encountered during the entire life span of patients with many forms of congenital or acquired heart disease, pulmonary disorders, and other diseases. Each pulmonary hypertensive patient requires anticipatory interventions geared to prevent severe exacerbations of the pulmonary hypertensive condition, promote pulmonary vasodilation, and optimize ventricular function. Patients with pulmonary hypertension are at higher risk for developing pulmonary hypertensive episodes in the immediate postoperative period after cardiac surgery, as well as during nonsurgical admissions. Nurses are in a critical position to provide anticipatory care to prevent the development of pulmonary hypertensive events. Nurses can be instrumental in optimizing outcomes for patients with pulmonary hypertension by providing immediate care upon the development of a pulmonary hypertension event and by monitoring ongoing responses to adjustments in therapeutic interventions.

    2013-01-01

    Background Surgery for pulmonary aspergillosis is infrequent and often challenging. Risk assessment is imprecise and new antifungals may ameliorate some surgical risks. We evaluated the medical and surgical management of these patients, including perioperative and postoperative antifungal therapy. Methods Retrospective study of patients who underwent surgery for pulmonary aspergillosis between September 1996 and September 2011. Results 30 patients underwent surgery with 23 having a preoperative tissue diagnosis while 7 were confirmed post-resection. The median age was 57 years (17–78). The commonest presenting symptoms were cough (40%, n = 12) and haemoptysis (43%, n = 13). Twelve (40%) patients had simple aspergilloma (including 2 with Aspergillus nodules) while the remaining 18 (60%) had chronic cavitary pulmonary aspergillosis (CCPA) (complex aspergilloma). Most of the patients had underlying lung disease: tuberculosis (20%, n = 6), asthma (26%, n = 8) and COPD (20%, n = 6). The procedures included lobectomy 50% (n = 15), pneumonectomy 10% (n = 3), sublobar resection 27% (n = 8), decortication 7% (n = 2), segmentectomy 3% (n = 1), thoracoplasty 3% (n = 1), bullectomy and pleurectomy 3% (n = 1), 6% (n = 2) lung transplantation for associated disease. Median hospital stay was 9.5 days (3–37). There was no operative and 30 day mortality. Main complications were prolonged air leak (n = 7, 23%), empyema (n = 6, 20%), respiratory failure requiring tracheostomy /reintubation (n = 4, 13%). Recurrence of CCPA was noted in 8 patients (26%), most having prior CCPA (75%). Taurolidine 2% was active against all 9 A. fumigatus isolates and used for pleural decontamination during surgery. Conclusions Surgery in patients with chronic pulmonary aspergillosis offered good outcomes with an acceptable morbidity in a difficult clinical situation; recurrence is problematic. PMID:23915502

    Context: Predictive models can be used to identify people at high risk of unplanned hospitalization, although some of the high-risk patients they identify may not be amenable to preventive care. This study describes the development of “impactibility models,” which aim to identify the subset of at-risk patients for whom preventive care is expected to be successful. Methods: This research used semistructured interviews with representatives of thirty American organizations that build, use, or appraise predictive models for health care. Findings: Impactibility models may refine the output of predictive models by (1) giving priority to patients with diseases that are particularly amenable to preventive care; (2) excluding patients who are least likely to respond to preventive care; or (3) identifying the form of preventive care best matched to each patient's characteristics. Conclusions: Impactibility models could improve the efficiency of hospital-avoidance programs, but they have important implications for equity and access. PMID:20579284

    2007-08-01

    Identification of high-risk individuals, genetic counseling, and informed consent are important components of a screening program for familial pancreatic cancer. Screening high-risk individuals with imaging tests, such endoscopic ultrasound (EUS) and computed tomography (CT), can lead to the detection and treatment of predominantly asymptomatic early pancreatic neoplasms, as well as extra-pancreatic tumors. These pancreatic neoplasms consist of resectable, mostly branch-type non-invasive intraductal papillary mucinous neoplasms (IPMNs). EUS can visualize these very early IPMNs as focal duct ectasias or cysts. EUS features of chronic pancreatitis are highly prevalent in high-risk individuals and these directly correlate with multifocal lobulocentric parenchymal atrophy due to multifocal pancreatic intraepithelial neoplasia (PanIN). No one molecular marker is ready for "prime time" screening of high-risk individuals. Translational studies are underway to discover novel biomarkers for IPMNs, PanIN-3 lesions, or microinvasive adenocarcinoma, which are likely to be cured by timely intervention. Long-term, multi-prospective studies are needed to determine if screening for early pancreatic neoplasia and timely intervention results in decreased pancreatic cancer incidence and mortality in high-risk individuals.

    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

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

    The 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.

    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 that 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 androgen-deprivation therapy (ADT), including use of newer agents such as abiraterone, 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.

    We report results of a retrospective analysis of 44 patients with relapsed and high-risk multiple myeloma (MM) undergoing allogeneic CD34-selected hematopoietic stem-cell transplantation (CD34-selected HSCT) from human leukocyte antigen (HLA)-compatible donors. Patients had multiply relapsed disease including relapse at <15 months after autologous transplant and most patients (28/44; 65%) also had high-risk cytogenetics. Before transplant, patients received busulfan (0.8 mg/kg X 10 doses), melphalan (70 mg/m2 X 2 days), fludarabine (25 mg/m2 X 5 days), and rabbit anti-thymocyte globulin (2.5 mg/kg X 2 days). Patients with 10/10 HLA-matched donors were treated prophylactically with low doses of donor lymphocyte infusions (0.5 to 1 X 106 CD3+/kg) starting at 4–6 months post CD34-selected HSCT. Acute (grade II–IV) graph-versus-host disease (GVHD) and transplant-related mortality at 12 months were 2% and 18%, respectively. Chronic GVHD was not observed in any patient. Overall and progression-free survival at 2 years was 54% and 31%, respectively. By multivariate analyses, the outcomes of CD34-selected HSCT were influenced by presence of extramedullary disease, disease status prior to CD34-selected HSCT and age. This study demonstrates notable safety and efficacy of CD34-selected HSCT in patients with multiply relapsed MM including those with high-risk cytogenetics. PMID:26325439

    Pulmonary arterial dissection is an extremely rare and usually lethal complication of chronic pulmonary hypertension. The condition usually manifests as cardiogenic shock or sudden death and is therefore typically diagnosed at postmortem examination rather than during life. However, recent isolated reports have described pulmonary artery dissection in surviving patients. The first case of pulmonary artery dissection in a surviving patient with cor pulmonale caused by chronic obstructive pulmonary disease is presented. The aetiology, pathophysiology, and clinical presentation of pulmonary artery dissection are reviewed and factors that may aid diagnosis during life are discussed.

    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.

    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.

    Purpose We aimed to investigate whether the apparent diffusion coefficient (ADC) value in diffusion-weighted magnetic resonance imaging predicts the prognoses of patients with high-risk prostate cancer. Materials and Methods A total of 157 patients with high-risk prostate cancer (based on D'Amico's criteria) were included in the analysis. Patients underwent preoperative 3.0 Tesla magnetic resonance imaging within 2 months before radical prostatectomy. Those who received neoadjuvant hormone therapy (33 persons) or radiation therapy (18 persons) were excluded. The ADC of the tumor calculated from 2 b-values (0 and 1,000 s/mm2) was measured. Areas under receiver operating characteristics curves were calculated to maximize the accuracy of the ADC value. Based on the obtained cutoff value, the patients were stratified into 2 groups: Group A consisted of patients with ADC values <746×10−6 mm2/s and group B comprised those with ADC values ≥746×10−6 mm2/s. Results Group A showed higher rate of lymph positive and biochemical recurrence (BCR) rates than group B. Kaplan-Meier analysis showed that the BCR-free survival rate of group A was much lower than that of group B (p<0.001). On Cox proportional regression analyses, ADC group A (hazard ratio [HR], 3.238, p=0.002) and pathologic lymph node positive (HR, 2.242; p=0.009) were independent predictors of BCR. Conclusions In patients with high-risk prostate cancer, ADC value is significantly associated with BCR-free survival. Therefore, the ADC value is a useful tool for predicting the prognoses of these high-risk patients. PMID:28097263

    Non-muscle-invasive bladder cancer (NMIBC) is categorized into high-risk and low-risk groups. Although, bacillus Calmette-Guerin (BCG) is the recommended adjuvant therapy of high-risk bladder tumor, optimal schedule (induction versus maintenance) of this therapy is a subject of debate. The objective was to evaluate outcomes of induction BCG in high-risk NMIBC patients at Shaukat Khanum Memorial Cancer Hospital & Research Centre, Pakistan and retrospective cohort study conducted in the department of urology, Shaukat Khanum Memorial Cancer Hospital & Research Centre, Pakistan. Three-year disease-free survival and progression-free survival was the main outcome measure. Data of 68 high-risk (Ta and T1 with G3 or high-grade subtype) bladder cancer patients who underwent transurethral resection followed by six-weekly intravesical BCG instillation was included in the study. Recurrence was described as biopsy-proven bladder cancer; whereas the presence of muscle invasion was considered as progression. Disease-free survival and progression-free survival were defined as time intervals elapsed between the starting date of BCG instillation and recurrence or progression, respectively. Kaplan-Meier curve was employed to estimate the three-year study end-points. Disease-free survival at three years was observed to be 66.2% and progression-free survival at 86.8%. The use of induction BCG alone for high-risk patients of NMIBC is a viable option both in terms of effective disease-free and progression-free survival rates. PMID:28168135

    Purpose Clinical guidelines recommend that people at high risk of melanoma receive regular surveillance to improve survival through early detection. A specialized High Risk Clinic in Sydney, Australia was found to be effective for this purpose; however, wider implementation of this clinical service requires evidence of cost-effectiveness and data addressing potential overtreatment of suspicious skin lesions. Patients and Methods A decision-analytic model was built to compare the costs and benefits of specialized surveillance compared with standard care over a 10-year period, from a health system perspective. A high-risk standard care cohort was obtained using linked population data, comprising the Sax Institute's 45 and Up cohort study, linked to Medicare Benefits Schedule claims data, the cancer registry, and hospital admissions data. Benefits were measured in quality-adjusted life-years gained. Sensitivity analyses were undertaken for all model parameters. Results Specialized surveillance through the High Risk Clinic was both less expensive and more effective than standard care. The mean saving was A$6,828 (95% CI, $5,564 to $8,092) per patient, and the mean quality-adjusted life-year gain was 0.31 (95% CI, 0.27 to 0.35). The main drivers of the differences were detection of melanoma at an earlier stage resulting in less extensive treatment and a lower annual mean excision rate for suspicious lesions in specialized surveillance (0.81; 95% CI, 0.72 to 0.91) compared with standard care (2.55; 95% CI, 2.34 to 2.76). The results were robust when tested in sensitivity analyses. Conclusion Specialized surveillance was a cost-effective strategy for the management of individuals at high risk of melanoma. There were also fewer invasive procedures in specialized surveillance compared with standard care in the community.

    A high-risk pregnancy can be a stressful situation for a woman, her partner and her family. Many women utilize their spiritual beliefs as a way to make sense of their situation. Health care professionals, including nurses, midwives and physicians, can provide effective spiritual care and support consistent with their professional scopes of practice. Spiritually focused interventions can help to reduce stress and anxiety and create a more open and confident approach to the management of pregnancy complications.

    Aims We aimed to document the drug management of patients at high cardiovascular risk in daily practice, with the special focus on lipid-lowering treatment. Methods and results In this prospective noninterventional study in 2387 outpatient centers throughout Germany, a total of 13,942 high-risk patients (mean age 65.7 years, 61.6% males) were treated with simvastatin 40 mg/day at entry as monotherapy. All patients were followed up for 12 months in terms of drug utilization, laboratory values, target attainment, and clinical events (including death, hospitalization, vascular events, and dialysis). Patients had coronary heart disease in 35.0%, diabetes mellitus in 24.4%, and the combination of coronary heart disease plus diabetes mellitus in 25.7%. In 21% of patients, a cholesterol absorption inhibitor was added to statin therapy at the entry visit, and in 23%, this was added at the follow up visit 6 months later. The target values for low-density lipoprotein-cholesterol (<2.6 mmol/L) were reached by 31.8% of patients at entry and by 50.0% at the end of this registry after 12 months. Mean blood pressure decreased (from 135.9/80.5 mmHg at baseline) by 3.1/1.9 mmHg after 12 months. In patients with documented diabetes, the targeted glycated hemoglobin (HbA1c <6.5%) was reached by 33.5% at baseline and by 40.0% after 12 months. Clinical events occurred in 11.7% of patients between baseline and month 6, and in 12.0% between months 6 and 12. Conclusion In patients at high risk for cardiovascular events, comprehensive management under daily practice conditions leads to improvement of lipid, glucose, and blood pressure parameters. There is a need to improve secondary prevention among high-risk patients. PMID:23459022

    Measurements of ovarian reserve play an important role in predicting the clinical results of assisted reproductive technology (ART). The ideal markers of ovarian reserve for clinical applications should have high specificity in order to determine genuine poor responders. Basal follicle-stimulating hormone levels, antral follicle count, and serum anti-Müllerian hormone (AMH) levels have been suggested as ovarian reserve tests that may fulfill this requirement, with serum AMH levels being the most promising parameter. Serum AMH levels have been suggested to be a predictor of clinical pregnancy in ART for older women, who are at a high risk for decreased ovarian response. We reviewed the prognostic significance of ovarian reserve tests for patients undergoing ART treatment, with a particular focus on the significance of serum AMH levels in patients at a high risk of poor ovarian response.

    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 < 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 < 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.

    Ovarian neoplasms secondary to germline BRCA mutations had been described to have a more favourable survival. There is only few data concerning the prognosis of non mutated patients presenting clinical features evocative of BRCA alterations. We retrospectively collected data from patients treated in our institution for an invasive ovarian carcinoma between 1995 and 2011. Patients considered at high risk of BRCA mutation were tested for BRCA1/2 germline mutations. We described clinical, pathological and therapeutic features and compared prognosis of BRCA mutation carriers and non-mutated patients. Out of 617 ovarian cancer patients, we identified 104 patients who were considered at high risk of mutation. The 33 mutated patients were more likely to present a personal (33 vs. 10 %, p = 0.003) or a family (42 vs. 24 %, p = 0.06) history of breast/ovarian cancers. BRCA1/2 mutation carriers and wild type patients displayed similar prognosis: median progression-free survival (PFS) of 20.9 versus 37.7 months (p = 0.21); median overall survival (OS) of 151.2 versus 122.5 months (p = 0.52). Personal history of breast cancer increased both PFS [HR = 0.45 (95CI 0.25-0.81)] and OS [HR = 0.35 (95CI 0.16-0.75)]. In multivariate analysis, this parameter was an independent prognostic feature, whereas the identification of a BRCA1/2 mutation was not. In our cohort, all patients at high risk of BRCA mutation share a similar prognosis, whatever is their germline mutation status. Prognosis seems to be more influenced by clinical history than by germline mutations identification. If it is confirmed in larger and independent series, this result suggests that the hypothesis of other BRCA pathway alterations (BRCAness phenotype) deserves to be deeply explored.

    Background Reliable neurofunctional markers of increased vulnerability to psychosis are needed to improve the predictive value of psychosis risk syndrome and inform preventive interventions. Methods I performed a signed differential mapping (SDM) voxel-wise meta-analysis of functional magnetic resonance imaging (fMRI) studies of patients at clinical high risk for psychosis. Results Ten studies were included in the analysis. Compared with controls, high-risk patients showed reduced neural activation in the left inferior frontal gyrus (Brodmann area [BA] 9) and in a cluster spanning the bilateral medial frontal gyrus (BA 8,6), bilateral superior frontal gyrus (BA 8,6) and the left anterior cingulate (BA 32). There was no publication bias. Heterogeneity across studies was low. Sensitivity analysis confirmed the robustness of the findings. Limitations The cross-sectional nature of the included studies prevented the comparison of high-risk patients who later experienced a psychotic episode with those who did not. Other caveats are reflected in methodologic heterogeneity across tasks employed by different individual imaging studies. Conclusion Reduced neurofunctional activation in prefrontal regions may represent a neurophysiologic correlate of increased vulnerability to psychosis. PMID:22146150

  17. Perioperative lung-protective ventilation strategy reduces postoperative pulmonary complications in patients undergoing thoracic and major abdominal surgery

    PubMed Central

    2016-01-01

    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.

    Background Impaired coronary vasodilation to both endothelial-dependent and endothelial-independent stimuli have been associated with atherosclerosis. Direct measurement of coronary vasodilation using x-ray angiography or intravascular ultrasound is invasive and, thus, not appropriate for asymptomatic patients or for serial follow-up. In this study, high-resolution coronary cardiovascular magnetic resonance (CMR) was used to investigate the vasodilatory response to nitroglycerine (NTG) of asymptomatic patients at high risk for CAD. Methods A total of 46 asymptomatic subjects were studied: 13 high-risk patients [8 with diabetes mellitus (DM), 5 with end stage renal disease (ESRD)] and 33 age-matched controls. Long-axis and cross-sectional coronary artery images were acquired pre- and 5 minutes post-sublingual NTG using a sub-mm-resolution multi-slice spiral coronary CMR sequence. Coronary cross sectional area (CSA) was measured on pre- and post-NTG images and % coronary vasodilation was calculated. Results Patients with DM and ESRD had impaired coronary vasodilation to NTG compared to age-matched controls (17.8 ± 7.3% vs. 25.6 ± 7.1%, p = 0.002). This remained significant for ESRD patients alone (14.8 ± 7.7% vs. 25.6 ± 7.1%; p = 0.003) and for DM patients alone (19.8 ± 6.3% vs. 25.6 ± 7.1%; p = 0.049), with a non-significant trend toward greater impairment in the ESRD vs. DM patients (14.8 ± 7.7% vs. 19.8 ± 6.3%; p = 0.23). Conclusion Noninvasive coronary CMR demonstrates impairment of coronary vasodilation to NTG in high-risk patients with DM and ESRD. This may provide a functional indicator of subclinical atherosclerosis and warrants clinical follow up to determine prognostic significance. PMID:18513419

  19. Identifying high-risk post-infarction patients by autonomic testing - Below the tip of the iceberg.

    PubMed

    Bauer, Axel

    2017-03-18

    Despite major advances in medical therapies late mortality after myocardial infarction (MI) is still high. A substantial proportion of post-MI patients die from sudden cardiac death. Prophylactic implantable-cardioverter defibrillator (ICD) therapy has been established for post-MI patients with reduced left ventricular ejection fraction (LVEF ≤35%). However, most patients who die after MI have an LVEF >35%. For this large group of patients, no specific prophylactic strategies exist. There is strong evidence that measures of cardiac autonomic dysfunction after MI provide important prognostic information in post-MI patients with preserved LVEF. Combinations of autonomic markers can identify high-risk patients after MI with LVEF >35% whose prognosis is equally worse than that of patients with LVEF ≤35%. The ongoing REFINE-ICD (NCT00673842) and SMART-MI trials (NCT02594488) test different preventive strategies in high-risk post-MI patients with cardiac autonomic dysfunction and LVEF 36-50%. While REFINE-ICD follows the traditional concept of ICD-implantation, SMART-MI uses implantable cardiac monitors with remote monitoring capabilities to sensitively detect asymptomatic, but prognostically relevant arrhythmias that could trigger specific diagnostic and therapeutic interventions.

    Extensive education in oral hygiene home care, nutrition counseling, and routine reinforcement of home-care instructions at periodic check-ups lead to better oral health for many young children and teenagers. In addition, resistance to dental caries infection can be increased significantly by intelligent use of bonded resin sealants and systemic and topical fluoride products. This article discusses protocols for use of in-office applied topical fluoride and daily at-home use of topical fluoride products for children and teens at high risk of dental caries.

    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.

    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.

    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.

    Positron emission tomography/computed tomography (PET/CT) is an important tool to identify occult melanoma metastasis. To date, it is controversial which patients with primary cutaneous melanoma should have staging PET/CT. In this retrospective analysis of more than 800 consecutive patients with cutaneous melanoma, we sought to identify factors predictive of PET/CT positivity in the setting of newly-diagnosed high-risk primary melanoma to determine those patients most appropriate to undergo a PET/CT scan as part of their diagnostic work up. 167 patients with newly-diagnosed high-risk primary cutaneous melanoma underwent a PET/CT scan performed as part of their initial staging. Clinical and histologic factors were evaluated as possible predictors of melanoma metastasis identified on PET/CT scanning using both univariate and multivariate logistic regression. In all, 32 patients (19.2%) had a positive PET/CT finding of metastatic melanoma. In more than half of these patients (56.3%), PET/CT scanning identified disease that was not detectable on clinical examination. Mitotic rate, tumor thickness, lymphadenopathy, and bleeding were significantly predictive of PET/CT positivity. A combinatorial index constructed from these factors revealed a significant association between number of high-risk factors observed and prevalence of PET/CT positivity, which increased from 5.8% (with the presence of 0-2 factors) to 100.0%, when all four factors were present. These results indicate that combining clinical and histologic prognostic factors enables the identification of patients with a higher likelihood of a positive PET/CT scan.

    Background Bilateral prophylactic mastectomy (BPM) has shown breast cancer risk reduction in high-risk/BRCA+ patients. However, priority of active cancers coupled with inefficient use of operating room (OR) resources presents challenges in offering BPM in a timely manner. To address these challenges, a rapid access prophylactic mastectomy and immediate reconstruction (RAPMIR) program was innovated. The purpose of this study was to evaluate RAPMIR with regards to access to care and efficiency. Methods We retrospectively reviewed the cases of all high-risk/BRCA+ patients having had BPM between September 2012 and August 2014. Patients were divided into 2 groups: those managed through the traditional model and those managed through the RAPMIR model. RAPMIR leverages 2 concurrently running ORs with surgical oncology and plastic surgery moving between rooms to complete 3 combined BPMs with immediate reconstruction in addition to 1–2 independent cases each operative day. RAPMIR eligibility criteria included high-risk/BRCA+ status; BPM with immediate, implant-based reconstruction; and day surgery candidacy. Wait times, case volumes and patient throughput were measured and compared. Results There were 16 traditional patients and 13 RAPMIR patients. Mean wait time (days from referral to surgery) for RAPMIR was significantly shorter than for the traditional model (165.4 v. 309.2 d, p = 0.027). Daily patient throughput (4.3 v. 2.8), plastic surgery case volume (3.7 v. 1.6) and surgical oncology case volume (3.0 v. 2.2) were significantly greater in the RAPMIR model than the traditional model (p = 0.003, p < 0.001 and p = 0.015, respectively). Conclusion A multidisciplinary model with optimized scheduling has the potential to improve access to care and optimize resource utilization. PMID:28234588

    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.

    Basal cell carcinoma (BCC) is the most common cancer in the United States today, and patients who have had one are likely to have multiple carcinomas over time. Predictors of new BCCs on the face and ears among those at very high risk have not been studied in detail. We sought to do so prospectively in the context of a 6-year trial. We found that the number of BCCs in the prior 5 years was the most important predictor. Age, sun sensitivity, occupational sun exposure before the age of 30 years (but not afterward), lower educational level, history of eczema, the use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and more sunscreen use in the week, but not the 6 months, before enrollment were also independent predictors, but sunburns, baseline sun exposure, and other sun-protective measures, other skin cancers, and actinic keratoses were not. None of the eczema patients had a history of topical calcineurin use. The cumulative risk of BCC was 55% at 5 years. These findings document the key risk factors in this very high-risk population, suggesting that the history of eczema may increase the risk in those at high risk and that early sun exposure is important even in this group, and underscoring the need for chemopreventive strategies.

    Introduction Emerging epidemiological data suggest that obstructive sleep apnoea (OSA) is common in the general surgical population. Unfortunately, the majority of these patients are unrecognised and untreated at the time of surgery. There is substantial biological rationale to indicate that patients with unrecognised OSA are at a higher risk of postoperative vascular events. However, the extent of this morbidity is currently unknown. We have initated the postoperative vascular complications in the unrecognised obstructive sleep apnoea (POSA) study to determine the associations between OSA, nocturnal hypoxia and major postoperative vascular events in 1200 moderate-to-high risk patients undergoing major non-cardiac surgery. Methods and analysis The POSA study is an international prospective observational cohort study. Using a type 3 portable sleep monitoring device and ambulatory oximetry, we will quantify the severity of OSA. The primary outcome is a composite of vascular death, myocardial infarction; non-fatal cardiac arrest; stroke; pulmonary embolism; congestive heart failure and new arrhythmia within 30 days of surgery. As of November 2013, we have recruited over 700 patients from nine centres in six countries. The mean age is 68 years, the mean body mass index is 27 kg/m2 and 55% of patients are men. 27.9% of patients have known coronary artery disease, over 76% have diabetes. The majority of patients underwent orthopaedic surgery (28%) and colorectal resection (18.5%). Ethics and dissemination The POSA study has received ethics approval from all study sites before patient recruitment. Informed consent will be obtained from all patients. The POSA study will determine the risk of unrecognised OSA in major non-cardiac surgery. We will publish these findings in peer-reviewed journals.

    Background Preventive strategies to reduce clinically significant medication errors (MEs), such as medication review, are often limited by human resources. Identifying high-risk patients to allow for appropriate resource allocation is of the utmost importance. To this end, we developed a predictive model to identify high-risk patients and assessed its impact on clinical decision-making. Methods From March 1st to April 31st 2014, we conducted a prospective cohort study on adult inpatients of a 1,644-bed University Hospital Centre. After a clinical evaluation of identified MEs, we fitted and internally validated a multivariate logistic model predicting their occurrence. Through 5,000 simulated randomized controlled trials, we compared two clinical decision pathways for intervention: one supported by our model and one based on the criterion of age. Results Among 1,408 patients, 365 (25.9%) experienced at least one clinically significant ME. Eleven variables were identified using multivariable logistic regression and used to build a predictive model which demonstrated fair performance (c-statistic: 0.72). Major predictors were age and number of prescribed drugs. When compared with a decision to treat based on the criterion of age, our model enhanced the interception of potential adverse drug events by 17.5%, with a number needed to treat of 6 patients. Conclusion We developed and tested a model predicting the occurrence of clinically significant MEs. Preliminary results suggest that its implementation into clinical practice could be used to focus interventions on high-risk patients. This must be confirmed on an independent set of patients and evaluated through a real clinical impact study. PMID:28192533

    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

    We sought to explore the pulmonary haemodynamic changes in rheumatic mitral stenosis patients with secondary pulmonary hypertension. The pulmonary artery resistance and compliance of 35 patients with rheumatic mitral stenosis and 12 controls without cardiopulmonary vascular disease were evaluated by using an improved method, which is based on making calculations with parameters obtained from right heart catheterisation. The results are as follows: (1) pulmonary artery compliance in patients with secondary pulmonary hypertension was significantly lower than that of the control group (P<0.01); (2) linear correlation analyses showed that preoperative mean pulmonary artery pressure (mPAP) closely correlated with zero-pressure compliance in the mitral stenosis group (r=-0.745, P<0.05); (3) PAP and pulmonary vascular resistance decreased significantly in both groups with mitral stenosis after infusing 0.5 μg kg(-1) min(-1) of sodium nitroprusside (P<0.01). The pulmonary zero pressure compliance and mean pressure compliance increased significantly in the group with mild pulmonary hypertension; whereas in the severe group, the mean compliance changed with significance as the mPAP decreased (1.51 ± 0.59 vs 1.81 ± 0.77 ml/mmHg), however no significant change occurred in the pulmonary zero pressure compliance (2.35 ± 1.24 ml/mmHg vs. 2.24 ± 1.53 ml/mmHg, P>0.05) The walls of pulmonary artery vessels in patients with pulmonary hypertension secondary to rheumatic mitral stenosis appeared to be remodelled by varying degrees as indicated by their haemodynamic properties. Structural remodelling may be a factor affecting preoperative pulmonary artery pressure. Mitral stenosis patients with severe pulmonary hypertension have significantly lower responses to sodium nitroprusside possibly due to aggradation and deposition of collagen in the artery walls, decreasing constriction and dilation, or atrophy of smooth muscle cells.

    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.

    Chronic lymphocytic leukemia (CLL) with deletions of the p53 locus on chromosome 17 and/or refractory to fludarabine chemoimmunotherapy remains a major clinical problem with few therapeutic options. Currently, these types of CLL are treated with approaches that do not target the p53 pathway, such as small molecules and monoclonal antibodies (mAb). We have previously postulated anti-CCR7 mAb therapy as a novel CLL treatment. In the present study, we evaluated the in vitro efficacy of anti-CCR7 mAb as a single agent in CLL patients with high-risk cytogenetics and/or refractory to fludarabine, by measuring CCR7 surface expression and complement-dependent cytotoxicity. Our results demonstrate that CCR7 is highly expressed in challenging and heavily treated CLL patients. In addition, the complement-mediated mechanism of action of this mAb effectively eradicates CLL cells while sparing subsets of T cells in these patients. Moreover, this mAb outperformed the activity of alemtuzumab, the mAb with the highest efficacy in these groups. Finally, in vitro activity was also demonstrated in patients with a disease refractory to both fludarabine and alemtuzumab, and patients harboring 11q22 deletion. Our results propose that anti-CCR7 mAb is an effective and promising future treatment in high-risk CLL.

    Standard treatment for operable patients with single peripheral lung metastases is metastasectomy. We report mature CyberKnife outcomes for high-risk surgical patients with biopsy proven single peripheral lung metastases. Twenty-four patients (median age 73 years) with a mean maximum tumor diameter of 2.5 cm (range, 0.8-4.5 cm) were treated over a 6-year period extending from September 2004 to September 2010 and followed for a minimum of 1 year or until death. A mean dose of 52 Gy (range, 45-60 Gy) was delivered to the prescription isodose line in three fractions over a 3-11 day period (mean, 7 days). At a median follow-up of 20 months, the 2-year Kaplan-Meier local control and overall survival rates were 87 and 50%, respectively. CyberKnife with fiducial tracking is an effective treatment for high-risk surgical patients with single small peripheral lung metastases. Trials comparing CyberKnife with metastasectomy for operable patients are necessary to confirm equivalence.

    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

    This is a case report of a 43-year-old Caucasian male with end-stage renal disease being treated with hemodialysis and infective endocarditis in the aortic and tricuspid valves. The clinical presentation was dominated by neurologic impairment with cerebral embolism and hemorrhagic components. A thoracoabdominal computerized tomography scan revealed septic pulmonary embolus. The patient underwent empirical antibiotherapy with ceftriaxone, gentamicin and vancomycin, and the therapy was changed to flucloxacilin and gentamicin after the isolation of S. aureus in blood cultures. The multidisciplinary team determined that the patient should undergo valve replacement after the stabilization of the intracranial hemorrhage; however, on the 8th day of hospitalization, the patient entered cardiac arrest due to a massive septic pulmonary embolism and died. Despite the risk of aggravation of the hemorrhagic cerebral lesion, early surgical intervention should be considered in high-risk patients.

    As the most suitable approach for preventing bisphosphonate-related osteonecrosis of the jaw (BRONJ) in patients undergoing surgical tooth extraction is still under discussion, the present study evaluates the incidence of BRONJ after surgical tooth extraction using a standardized surgical protocol in combination with an adjuvant perioperative treatment setting in patients who are at high-risk for developing BRONJ. High-risk patients were defined as patients who received intravenous bisphosphonate (BP) due to a malignant disease. All teeth were removed using a standardized surgical protocol. The perioperative adjuvant treatment included intravenous antibiotic prophylaxis starting at least 24 h before surgery, a gastric feeding tube and mouth rinses with chlorhexidine (0.12%) three times a day. In the follow-up period patients were examined every 4 weeks for the development of BRONJ. Minimum follow-up was 12 weeks. In 61 patients a total number of 184 teeth were removed from 102 separate extraction sites. In eight patients (13.1%) BRONJ developed during the follow-up. A higher risk for developing BRONJ was found in patients where an additional osteotomy was necessary (21.4% vs. 8.0%; p = 0.0577), especially for an osteotomy of the mandible (33.3% vs. 7.3%; p = 0.0268). Parameters including duration of intravenous antibiotic prophylaxis, the use of a gastric feeding tube and the duration of intravenous BP therapy showed no statistical impact on the development of BRONJ. Furthermore, patients currently undergoing intravenous BP therapy showed no higher risk for BRONJ compared with patients who have paused or completed their intravenous BP therapy (p = 0.4232). This study presents a protocol for surgical tooth extraction in high-risk BP patients in combination with a perioperative adjuvant treatment setting, which reduced the risk for postoperative BRONJ to a minimum. However, the risk for BRONJ increases significantly if an additional osteotomy is necessary

    Summary Background Ibrutinib, an orally administered covalent inhibitor of Bruton tyrosine kinase (BTK), is an effective therapy for patients with relapsed chronic lymphocytic leukemia (CLL). We investigated the activity and safety of the combination of ibrutinib with the monoclonal antibody rituximab (iR) in patients with high-risk CLL. Methods In this single-arm, phase 2 studywe enrolled 40 patients with high-risk CLL at MD Anderson Cancer Center, Houston, Texas, USA. Patients with symptomatic CLL requiring therapy received 28 day cycles of once-daily ibrutinib 420 mg , together with rituximab (weekly during cycle 1, then once per cycle until cycle 6), followed by continuous single-agent ibrutinib. The primary endpoint was progression-free survival (PFS) in the intention-to-treat population. This study is registered with ClinicalTrials.gov, number NCT01520519 and is no longer accruing patients. Findings Between February 28, 2012 and September 11, 2012, we enrolled 40 CLL patients with high-risk disease features. 20 patients had del17p or TP53 mutations (16 previously treated, 4 untreated), 13 had relapsed CLL with del11q, and 7 patients a PFS < 36 months after frontline chemo-immunotherapy. Toxicity was mainly of mild to moderate severity (grade 1–2). 10 (25%) patients had diarrhea (grade 1 in 9 [22.5%] patients, grade 2 in 1 [2.5%]), bleeding events occurred in 14 (35%) patients (8 [20%] patients with grade 1, 5 [12.5%] patients grade 2, and 1 [2.5%] grade 3), nausea in 15 (37.5) patients (10 [25%] grade 1, 5 [12.5%] grade 2), and fatigue in 7 (17.5%) patients (4 [10%] grade 1, 3 [7.5%] grade 2). Grade 3 infections occurred in 4 patients (10%), no grade 4 or 5 infections occurred. At 18 months, the Kaplan Meier estimate of progression-free survival was 78% (95% CI 60.6–88.5) (del[17p] or TP53 mutation: 72%, 95% CI: 45.6–87.6) Interpretation Ibrutinib in combination with rituximab is a well-tolerated regimen for patients with high-risk CLL. It induces high

    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

    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.

    Pulmonary rehabilitation has been shown to be an important part of the management of patients with chronic obstructive pulmonary disease (COPD). Exercise training is the corner stone of a comprehensive, multidisciplinary pulmonary rehabilitation in COPD and has been shown to improve health-related quality of life and exercise capacity. Nevertheless, not every COPD patient responds well to pulmonary rehabilitation. Future trials should focus on new additions to conventional pulmonary rehabilitation programmes to optimise its effects on health-related quality of life, exercise capacity, body composition and muscle function in patients with COPD. Therefore, a patient-tailored approach is inevitable. Advantages and disadvantages of new modalities of pulmonary rehabilitation will be outlined in detail, including the following: endurance training and long-acting bronchodilatators; endurance training and technical modalities (inspiratory pressure support and inspiratory muscle training); interval training; resistance training; transcutaneous neuromuscular electrical stimulation; and exercise training and supplements (oxygen, oral creatine, anabolic steroids and polyunsaturated fatty acids). Based on well defined baseline characteristics, patients should most probably be individually selected. At present, these new modalities of pulmonary rehabilitation have been shown to improve body composition, skeletal muscle function and sometimes also exercise capacity. However, the translation to an improved health-related quality of life is mostly lacking, and cost effectiveness and long-term effects have not been studied. Moreover, future trials should study the effects of pulmonary rehabilitation in elderly patients with restrictive pulmonary diseases.

    In order to determine the frequency of extended use of non-steroidal anti-inflammatory drugs (NSAID) in Colombian patients with high cardiovascular risk (HCVR), a retrospective study was developed which identified HCVR patients who used NSAID for over five continuous months from January 2011 and March 2013. Patients chronically receiving nitrates, digitalis and clopidogrel and acetylsalicylic acid (ASA), known as HCVR, were identified. An analysis of the frequencies of use based on the co-medication received was performed. Concomitant use of NSAID was found in 0,35% of consumers of nitrates (average time: 9,5 ± 4,4 months), in 0,36% of consumers of clopidogrel and ASA (average time: 9,3 ± 3,4 months), and in 0,4% of consumers of digitalis (10,2 ± 4,6 months). It is concluded that there is a low proportion of chronic use of NSAID in high-risk cardiovascular patients.

    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.

    Background The prevalence of pulmonary embolism among patients hospitalized for syncope is not well documented, and current guidelines pay little attention to a diagnostic workup for pulmonary embolism in these patients. Methods We performed a systematic workup for pulmonary embolism in patients admitted to 11 hospitals in Italy for a first episode of syncope, regardless of whether there were alternative explanations for the syncope. The diagnosis of pulmonary embolism was ruled out in patients who had a low pretest clinical probability, which was defined according to the Wells score, in combination with a negative d-dimer assay. In all other patients, computed tomographic pulmonary angiography or ventilation-perfusion lung scanning was performed. Results A total of 560 patients (mean age, 76 years) were included in the study. A diagnosis of pulmonary embolism was ruled out in 330 of the 560 patients (58.9%) on the basis of the combination of a low pretest clinical probability of pulmonary embolism and negative d-dimer assay. Among the remaining 230 patients, pulmonary embolism was identified in 97 (42.2%). In the entire cohort, the prevalence of pulmonary embolism was 17.3% (95% confidence interval, 14.2 to 20.5). Evidence of an embolus in a main pulmonary or lobar artery or evidence of perfusion defects larger than 25% of the total area of both lungs was found in 61 patients. Pulmonary embolism was identified in 45 of the 355 patients (12.7%) who had an alternative explanation for syncope and in 52 of the 205 patients (25.4%) who did not. Conclusions Pulmonary embolism was identified in nearly one of every six patients hospitalized for a first episode of syncope.

    Background: There has been a constant emphasis on developing management strategies to improve the outcome of high-risk cardiac patients undergoing surgical revascularization. The performance of coronary artery bypass surgery on an off-pump coronary artery bypass (OPCAB) avoids the risks associated with extra-corporeal circulation. The preliminary results of goal-directed therapy (GDT) for hemodynamic management of high-risk cardiac surgical patients are encouraging. The present study was conducted to study the outcome benefits with the combined use of GDT with OPCAB as compared to the conventional hemodynamic management. Material and Method: Patients with the European System for Cardiac Operative Risk Evaluation ≥3 scheduled for OPCAB were randomly divided into two groups; the control and GDT groups. The GDT group included the monitoring and optimization of advanced parameters, including cardiac index (CI), systemic vascular resistance index, oxygen delivery index, stroke volume variation; continuous central venous oxygen saturation (ScVO2), global end-diastolic volume, and extravascular lung water (EVLW), using FloTrac™, PreSep™, and EV-1000® monitoring panels, in addition to the conventional hemodynamic management in the control group. The hemodynamic parameters were continuously monitored for 48 h in Intensive Care Unit (ICU) and corrected according to GDT protocol. A total of 163 patients consented for the study. Result: Seventy-five patients were assigned to the GDT group and 88 patients were in the control group. In view of 9 exclusions from the GDT group and 12 exclusions from control group, 66 patients in the GDT group and 76 patients in control group completed the study. Conclusion: The length of stay in hospital (LOS-H) (7.42 ± 1.48 vs. 5.61 ± 1.11 days, P < 0.001) and ICU stay (4.2 ± 0.82 vs. 2.53 ± 0.56 days, P < 0.001) were significantly lower in the GDT group as compared to control group. The duration of inotropes (3.24 ± 0.73 vs. 2.89

    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.

    Clinical outcomes for multiple myeloma (MM) are highly heterogeneous and it is now clear that pivotal genetic events are the primary harbingers of such variation. These findings have broad implications for counseling, choice of therapy and the design and interpretation of clinical investigation. Indeed, as in acute leukemias and non-hodgkins lymphoma, we believe it is no longer acceptable to consider MM a single disease entity. As such, the accurate diagnosis of MM subtypes and the adoption of common criteria for the identification and stratification of MM patients has become critical. Herein, we provide a consensus high-risk definition and offer practical guidelines for the adoption of routine diagnostic testing. Although acknowledging that more refined classifications will continue to be developed, we propose that the definition of high-risk disease (any of the t(4;14), t(14;16), t(14;20), deletion 17q13, aneuploidy or deletion chromosome 13 by metaphase cytogenetics, or plasma cell labeling index >3.0) be adopted. This classification will identify most of the 25% of MM patients for whom current therapies are inadequate and for whom investigational regimens should be vigorously pursued. Conversely, the 75% of patients remaining have more favorable outcomes using existing - albeit non-curative - therapeutic options.

    In this study, 52 high risk patients who underwent operations upon the biliary tract were assigned to receive either antibiotic prophylaxis or no treatment with antibiotics. Twenty-seven patients were given 2 grams of cefamandole intramuscularly 30 minutes before operation and 2 grams every eight hours for two days postoperatively. The remaining patients were in the control group and did not receive antibiotics. Surgical wounds were inspected daily by a surgeon while the patients were in the hospital and a follow-up revision was done four weeks after discharge from the hospital. Samples of exudate or pus were taken when the wound appeared infected and cultures of aerobic and anaerobic organism done. Chi-square affinity test with Yate's correction was used for statistical results; only p values more than or equal to 0.5 were considered significant. Seven patients (28 per cent) in the control group had complications develop postoperatively; seven surgical wound infections, one of which included a subphrenic abscess. Postoperatively, there were no septic complications in the group who received cefamandole as a prophylaxis. The incidence of infection was higher for females than males. The organisms most frequently isolated were Escherichia coli and Klebsiella; only in one instance was Clostridum sporogenes found. Polymicrobial infections accounted for 42.8 per cent of the infections. No incidences were reported with the use of cefamandole in those patients who were treated prophylactically. In view of these results, we believe that cefamandole is an ideal antibiotic to be used in the prophylactic treatment of infections of high risk patients who undergo operations upon the biliary tract.

    OBJECTIVES Sternal wound infections occurring after cardiac surgery have a critical impact on morbidity, mortality and hospital costs. This study evaluated the efficacy of a gentamicin–collagen sponge in decreasing deep sternal-wound infections in high-risk cardiac surgery patients. METHODS We conducted a quasi-experimental single-centre prospective cohort study in diabetic and/or overweight patients undergoing coronary-artery bypass surgery with bilateral internal mammary artery grafts. The end-point was the rate of reoperation for deep sternal wound infection. The period from January 2006 to October 2008, before the introduction of the gentamicin sponge, was compared with the period from November 2008 to December 2010. RESULTS Of 552 patients (median body mass index, 31.5; 37.7% with diabetes requiring insulin), 68 (12.3%) had deep sternal wound infections. Reoperation for deep sternal wound infections occurred in 40/289 (13.8%) preintervention patients and 22/175 (12.6%) patients managed with the sponge. Independent risk factors were female sex and longer time on mechanical ventilation, but not use of the sponge (adjusted odds ratio, 0.95; 95% confidence interval, 0.52–1.73; P = 0.88). The group managed with the sponge had a higher proportion of gentamicin-resistant micro-organisms (21/27, 77.8%) compared with the other patients (23/56, 41.1%; P < 0.01). The median time to reoperation for wound infection was higher with the sponge (21 vs 17 days, P < 0.01). CONCLUSIONS A gentamicin–collagen sponge was not effective in preventing deep sternal wound infections in high-risk patients. Our results suggest that a substantial proportion of wound contaminations occur after bypass surgery with bilateral internal mammary artery grafts. PMID:23115102

    The HOPE and EUROPA clinical studies have shown that treatment with the angiotensin-converting enzyme (ACE) inhibitors, ramipril and perindopril, may reduce the occurrence of major cardiovascular events in patients with proven atherosclerotic disease. The recently published results of the PRoFESS and TRANSCEND trials completed the much needed information concerning the use of an angiotensin receptor blocker for patients at high risk of cardiovascular events. PROFESS compared a therapy of telmisartan 80 mg daily with placebo in patients with a recent ischemic stroke. The difference in the primary outcome of first recurrent stroke was not statistically significant between telmisartan and placebo. The secondary outcome of major cardiovascular events showed a relative risk reduction (RRR) of 7% in favour of telmisartan. This tended to be significant (p = 0.06) despite a rather short follow-up period of only 28 months. In TRANSCEND 5926 patients at high risk for cardiovascular events were randomized to a treatment with telmisartan 80 mg daily or placebo for a mean duration of follow-up of 56 months. The primary composite outcome of cardiovascular death, myocardial infarction, stroke or hospitalization for heart failure showed a non-significant 8% RRR in favour of the telmisartan treated patients. The main secondary outcome of cardiovascular death and myocardial infarction or stroke as used in the HOPE trial showed a non-significant RRR of 13% in favour of telmisartan treated patients (p = 0.068 adjusted for multiplicity of comparisons). In comparing the Kaplan-Meier curves for the endpoint of major cardiovascular events used in HOPE, EUROPA, TRANSCEND and PRoFESS, the trends are similar. Results of most of the recently published trials have been neutral.This could partly be explained by major improvements in the optimal background therapy of the patients included. Nevertheless, the results of PRoFESS and TRANSCEND do not contradict the results from previous studies with

    Right ventricle insufficiency due to pulmonary hypertensive crysis or persisting pulmonary arterial hypertension (PAH) in patients after the interventricle septum defect (IVSD) closure with the heightened resistance of pulmonary arteries (RPA) constitutes an actual problem and associates with a high risk for a life-threatening complications and high lethality. Experience of the IVSD plasty conduction in a patient with high PAH, using a patch with a valve for right ventricle decompression while pulmonary hypertensive crysis in early postoperative period and nonreversible PAH in the remote period of observation, was presented. In the clinic 38 children were operated on for big IVSD, complicated by high PAH and heightened RPA, using a patch with a valve in 1996 - 2014 yrs. Hospital lethality have constituted 2.6%. Postoperatively a pressure in pulmonary artery (PA) have lowered trustworthy from (93.4 ? 14.9) to (49.2 ? 22.9) mm Hg. In a remote period of observation all the patients were alive. In 6 (16.2%) patients in terms from 4 mo to 18 yrs postoperatively a PAH have occurred, a pressure in PA was by 50% higher, than a systemic one. The IVSD plasty in patients with high PAH and heightened RPA may appear successful if a patch with a valve are applied.

    Extended pharmacological venous thromboembolism (VTE) prophylaxis beyond discharge is recommended for patients undergoing high-risk surgery. We prospectively investigated prophylaxis in 1,046 consecutive patients undergoing major orthopaedic (70%) or major cancer surgery (30%) in 14 Swiss hospitals. Appropriate in-hospital prophylaxis was used in 1,003 (96%) patients. At discharge, 638 (61%) patients received prescription for extended pharmacological prophylaxis: 564 (77%) after orthopaedic surgery, and 74 (23%) after cancer surgery (p < 0.001). Patients with knee replacement (94%), hip replacement (81%), major trauma (80%), and curative arthroscopy (73%) had the highest prescription rates for extended VTE prophylaxis; the lowest rates were found in patients undergoing major surgery for thoracic (7%), gastrointestinal (19%), and hepatobiliary (33%) cancer. The median duration of prescribed extended prophylaxis was longer in patients with orthopaedic surgery (32 days, interquartile range 14-40 days) than in patients with cancer surgery (23 days, interquartile range 11-30 days; p<0.001). Among the 278 patients with an extended prophylaxis order after hip replacement, knee replacement, or hip fracture surgery, 120 (43%) received a prescription for at least 35 days, and among the 74 patients with an extended prophylaxis order after major cancer surgery, 20 (27%) received a prescription for at least 28 days. In conclusion, approximately one quarter of the patients with major orthopaedic surgery and more than three quarters of the patients with major cancer surgery did not receive prescription for extended VTE prophylaxis. Future effort should focus on the improvement of extended VTE prophylaxis, particularly in patients undergoing major cancer surgery.

  18. 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

    Percutaneous pulmonary valve technology has had a great impact on patients with congenital and acquired heart disease. In some patients, implantation of a percutaneous pulmonary valve may not be possible due to the morphology of the existing right ventricular outflow tract. In this report, we describe implantation of a Melody transcatheter pulmonary valve in the left pulmonary artery in a patient with acquired right pulmonary artery occlusion and a large right ventricular outflow tract.

    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.

    We determined the retention rate of patients infected with HIV who resumed care after being tracked at the Infectious Diseases Clinic (IDC) in Kampala, Uganda. Between April 2011 and September 2013, patients who missed their clinic appointment for 8-90 days were tracked, and those who returned to the clinic within 120 days were followed up. The proportion of patients retained among tracked patients, and those who resumed care before tracking started was compared. At 18 months of follow up, 33 (39%) of the tracked patients and 72 (61%) of those who had resumed care before tracking started were retained in care. The most important cause of attrition among the traceable was self-transfer to another clinic (38 [73%] patients), whereas among those who resumed care before tracking was loss to follow up (LTFU) (32 [71%] patients). Tracked patients who resume care following a missed appointment are at high risk of attrition. To increase retention, antiretroviral therapy clinics need to adopt a chronic care model which takes into consideration patients' changing needs and their preference for self-management.

    Background The purpose of this study was to assess the efficacy of open lung biopsy (OLB) in determining the specific diagnosis and the related complications in patients with undiagnosed diffuse pulmonary infiltrates. Methods This single center, retrospective study included adult kidney transplant patients who underwent OLB. The patients had diffuse pulmonary infiltrates without definitive diagnoses and failed to respond to empiric antibiotic treatment. We analyzed the number of specific diagnoses, changes in treatment and the occurrence of complications in these patients. A logistic regression was used to determine which variables were predictors of hospital mortality. Results From April 2010 to April 2014, 87 patients consecutively underwent OLB. A specific diagnosis was reached in 74 (85.1%) patients. In 46 patients (53%), their therapeutic management was changed after the OLB results. Twenty-five (28.7%) patients had complications related to the OLB. The hospital mortality rate was 25.2%. Age, SAPS3 score and complications related to the procedure were independent predictors of all-cause mortality. Conclusions OLB is a high-risk procedure with a high diagnostic yield in kidney transplant patients with diffuse pulmonary infiltrates who did not have a definitive diagnosis and who failed to respond to empiric antibiotic treatment. Complications related to OLB were common and were independently associated with intra-hospital mortality. PMID:28203420

    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.

    Objective The purpose of this study was to determine MRI screening recommendations and the subsequent outcomes in women with increased risk for breast cancer evaluated by oncology subspecialists at an academic center. Patients and Methods Patients evaluated between 1/1/2007– 3/1/2011 under diagnosis codes for family history of breast or ovarian cancer, genetic syndromes, lobular carcinoma in situ or atypical hyperplasia were included. Patients with a history of breast cancer were excluded. Retrospective review of prospectively acquired demographics, lifetime risk of breast cancer and screening recommendations were obtained from the medical record. Retrospective review of the results of prospectively interpreted breast imaging examinations and image-guided biopsies were analyzed. Results 282 women were included. The majority of patients were premenopausal with a median age of 43. Most (69%) were referred due to a family history of breast or ovarian cancers. MRI was recommended for 84% of patients based on a documented lifetime risk > 20%. Most women referred for MRI screening (88%) were compliant with this recommendation. A total of 299 breast MRI examinations were performed in 146 patients. Biopsy was performed for 32 (11%) exams and 10 cancers were detected for a PPV of 31% (based on biopsy performed) and an overall per exam cancer yield of 3.3%. Three cancers were detected in patients who did not undergo screening MRI. The 13 cancers were Stage 0-II; all patients were without evidence of disease with a median follow-up of 22 months. Conclusion In a cohort of women seen by breast subspecialty providers, screening breast MRI was recommended according to guidelines, and used primarily premenopausal women with a family history or genetic predisposition to breast cancer. Adherence to MRI screening recommendations was high and cancer yield from breast MRI was similar to that in clinical trials. PMID:25789917

    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.

    Background Pulmonary rehabilitation can improve the quality of life and ability to function of patients with chronic obstructive pulmonary disease (COPD). It may also reduce hospital admission and inpatient stay with exacerbations of COPD. Some patients who are eligible for pulmonary rehabilitation may not accept an offer of it, thereby missing an opportunity to improve their health status. Aim To identify a strategy for improving the uptake of pulmonary rehabilitation. Design of study Qualitative interviews with patients. Setting Patients with COPD were recruited from a suburban general practice in north-east Derbyshire, UK. Method In-depth interviews were conducted on a purposive sample of 16 patients with COPD to assess their concerns about accepting an offer of pulmonary rehabilitation. Interviews were analysed using grounded theory. Results Fear of breathlessness and exercise, and the effect of pulmonary rehabilitation on coexisting medical problems were the most common concerns patients had about taking part in the rehabilitation. The possibility of reducing the sensation of breathlessness and regaining the ability to do things, such as play with their grandchildren, were motivators to participating. Conclusion A model is proposed where patients who feel a loss of control as their disease advances may find that pulmonary rehabilitation offers them the opportunity to regain control. Acknowledging patients' fears and framing pulmonary rehabilitation as a way of ‘regaining control’ may improve patient uptake. PMID:18826782

    Transcatheter aortic valve implantation (TAVI) represents a real revolution in the field of interventional cardiology for the treatment of elderly or high-risk surgical patients with severe symptomatic aortic valve stenosis. Today, TAVI seems to play a key and a reliable role in the treatment of intermediate and maybe low-risk patients with severe aortic stenosis. TAVI has also evolved from a complex and hazardous procedure into an effective and safe therapy by the development of new generation devices. This article aims to review the background and future of TAVI, clinical trials and registries with old and new generation TAVI devices and to focus on some open issues related to post-procedural outcomes.

    Background: The aim of the study was to determine the correlation between clinical and echocardiographic findings and risk factors of patients with suspected acute pulmonary thromboembolism (PTE) who underwent computed tomography pulmonary angiography (CTPA). Materials and Methods: In this cross-sectional study, 310 hospitalized patients aged >18 years with high clinical suspicion of PTE referred to imaging center of our hospital from different wards for CTPA were enrolled. The frequency of different clinical presentations, risk factors, items of Wells’ criteria, and echocardiographic findings was compared in patients with and without PTE, which have been diagnosed according to the CTPA results. Results: PTE was diagnosed in 53 (17.1%) of patients with suspected PTE. From clinical manifestations, tachypnea, pleuritic chest pain, and edema of lower extremities were significantly more frequent among patients with PTE (P < 0.05). Major surgery was the risk factor which was significantly more prevalent among patients with PTE (P < 0.05). Frequency of all criteria of Wells’ criteria, except hemoptysis, was significantly higher in patients with PTE (P < 0.05). The frequency of all studied echocardiographic variables was significantly higher in patients with PTE (P < 0.05). Conclusion: It is suggested that we could use the results of this study for utilizing the diagnostic process of PTE in patients with highly clinical suspicion of PTE and providing more validated decision. Using the results of this study, we could identify high-risk patients and made appropriate risk assessment for better management of patients with suspected PTE as well as reduce the rate of unnecessary CTPA and its related adverse consequences.

    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

    Co-management and critical care outreach for high risk surgical patients have been proposed to decrease postoperative complications and mortality. We proposed that a clinical project with postoperative comanagement and critical care outreach, the Post Operative Surveillance Team: (POST), would be associated with decreased hospital length of stay. We conducted a retrospective before (control group) and after (POST group) audit of this hospital program. POST was staffed for four months in 2010 by two intensive care nurses and two senior registrars who conducted daily ward rounds for the first five postoperative days on high risk patients undergoing inpatient general or urological surgery. The primary endpoint was length of hospital stay and secondary endpoints were Medical Emergency Team (MET) calls, cardiac arrests and in-hospital mortality. There were 194 patients in the POST group and 1,185 in the control group. The length of stay in the POST group, median nine days (Inter-quartile range [IQR]: 5 to 17 days), was longer than the control group, median seven days (IQR: 4 to 13 days): difference two days longer (95.0% confidence interval [95.0% CI]: 1 to 3 days longer, P <0.001). There were no important differences in the proportion of patients having MET calls (16.0% POST versus. 13% control (P=0.25)) or mortality (2.1% POST versus 2.8% Control (P=0.82)). Our audit found that the POST service was not associated with reduced length of stay. Models of co-management, different to POST, or with different performance metrics, could be tested.

    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.

    Patients with chronic obstructive pulmonary disease (COPD) are often at high risk of early death. Identification of prognostic biomarkers for COPD may aid in improving their survival by providing early strengthened therapy for high-risk patients. In the present study, we investigated the prognostic role of hyperuricemia at baseline on the prognosis of patients with COPD. Thirty-four patients with COPD with hyperuricemia were matched (1:2) to 68 patients with COPD without hyperuricemia and of similar age and sex. Data from those patients with COPD were evaluated retrospectively. The role of hyperuricemia on mortality was first analyzed using the Kaplan-Meier method, and multivariate Cox regression model was then used to evaluate the prognostic significance of hyperuricemia in patients with COPD. Hyperuricemia was not associated with other baseline characteristics in patients with COPD. Kaplan-Meier survival curve showed that patients with COPD with hyperuricemia had higher risk of mortality compared with patients with normouricemia, and the P-value for log-rank test was 0.005. In univariate analysis, hyperuricemia was associated with higher risk of mortality in patients with COPD (hazard ratio =2.29, 95% CI =1.07-4.88, P=0.032). In the multivariate analysis, hyperuricemia was independently associated with higher risk of mortality in patients with COPD (hazard ratio =2.68, 95% CI =1.18-6.09, P=0.019). In conclusion, hyperuricemia is a promising biomarker of early mortality in patients with COPD.

    Structured Abstract Introduction The most common types of cervical cancer are squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinoma, referred to here collectively as SA cervical cancer. Other types of cervical cancer, referred to here collectively as nonsquamous/nonadenocarcinoma (NSNA) cervical cancer, include neuroendocrine, small cell, clear cell, sarcomatoid, and serous tumors. Anecdotally, NSNA tumors seem to have a worse prognosis than their SA counterparts. We sought to determine whether patients with early-stage NSNA have a worse prognosis than those with early-stage SA cervical cancer. Methods We retrospectively reviewed charts of women with stage IA1-IB2 NSNA cervical cancer treated by radical hysterectomy and lymph node staging at MD Anderson Cancer Center from 1990 to 2006. NSNA patients were matched 1:2 to patients with grade 3 SA lesions on the basis of stage, age at diagnosis, tumor size, and date of diagnosis. Results Eighteen patients with NSNA primary cervical cancer subtypes [neuroendocrine (n=7), small cell (5), clear cell (4), papillary serous (1), and sarcomatoid (1)] were matched to 36 patients with grade 3 SA lesions. There were no differences between the 2 groups in age, body mass index, clinical stage, or lesion size. The 2 groups also did not differ with respect to number of nodes resected, lymphovascular space invasion, margin status, lymph node metastasis, or adjuvant radiation therapy or chemotherapy. At a median follow-up of 44 months, median progression-free and overall survivals had not been reached; however, both progression-free survival (p=0.018) and overall survival (p=0.028) were worse for the NSNA group. The 5-year progression-free and overall survival rates were 61.2% and 67.6%, respectively, for the NSNA group, compared to 90.1% and 88.3%, respectively, for the SA group. Conclusions Patients with early-stage NSNA cervical cancer undergoing radical hysterectomy and pelvic lymphadenectomy have a worse prognosis

    The choice of a single or bilateral lung transplant for interstitial lung disease (ILD) is controversial, as surgical risk, long-term survival and organ allocation are competing factors. In an effort to balance risk and benefit, our center adopted a staged bilateral lung transplant approach for higher surgical risk ILD patients where the patient has a single lung transplant followed by a second single transplant at a later date. We sought to understand the surgical risk, organ allocation and early outcomes of these staged bilateral recipients as a group and in comparison to matched single and bilateral recipients. Our analysis demonstrates that staged bilateral lung transplant recipients (n = 12) have a higher lung allocation score (LAS), lower pulmonary function tests and a lower glomerular filtration rate prior to the first transplant compared to the second (p < 0.01). There was a shorter length of hospital stay for the second transplant (p = 0.02). The staged bilateral compared to the single and bilateral case-matched controls had comparable short-term survival (p = 0.20) and pulmonary function tests at 1 year. There was a higher incidence of renal injury in the conventional bilateral group compared to the single and staged bilateral groups. The staged bilateral procedure is a viable option in select ILD patients.

  17. Pulmonary Rehabilitation in Patients with Neuromuscular Disease

    PubMed Central

    2006-01-01

    In neuromuscular disease (NMD) patients with progressive muscle weakness, respiratory muscles are also affected and hypercapnia can increase gradually as the disease progresses. The fundamental respiratory problems NMD patients experience are decreased alveolar ventilation and coughing ability. For these reasons, it is necessary to precisely evaluate pulmonary function to provide the proper inspiratory and expiratory muscle aids in order to maintain adequate respiratory function. As inspiratory muscle weakening progresses, NMD patients experience hypoventilation. At this point, respiratory support by mechanical ventilator should be initiated to relieve respiratory distress symptoms. Patients with adequate bulbar muscle strength and cognitive function who use a non-invasive ventilation aid, via a mouthpiece or a nasal mask, may have their hypercapnia and associated symptoms resolved. For a proper cough assist, it is necessary to provide additional insufflation to patients with inspiratory muscle weakness before using abdominal thrust. Another effective method for managing airway secretions is a device that performs mechanical insufflation-exsufflation. In conclusion, application of non-invasive respiratory aids, taking into consideration characterization of respiratory pathophysiology, have made it possible to maintain a better quality of life in addition to prolonging the life span of patients with NMD.

    Myelodysplastic syndromes (MDS) represent a clonal hematopoietic stem cell disorder characterized by morphologic features of dyspoiesis, a hyperproliferative bone marrow, and one or more peripheral blood cytopenias. In patients classified according to the Revised International Prognostic Scoring System (R-IPSS) with intermediate or higher-risk disease, there is an increased risk of death due to progressive bone marrow failure or transformation to acute myeloid leukemia (AML). Azacitidine was the first DNA hypomethylating agent approved by the United States (US) Food and Drug Administration (FDA) for the treatment of MDS and the only therapy that has demonstrated a significant survival benefit over conventional care regimens (CCRs) in patients with intermediate or higher-risk disease. Prolonged survival is independent of achieving a complete remission. Azacitidine has been used in older patients with both clinical and hematological improvement as well as an acceptable side effect profile. The most common adverse effect is myelosuppression. These findings support the use of azacitidine as an effective treatment in older patients with higher-risk MDS. PMID:28042456

    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.

    Pulmonary infections in critically ill patients are common and associated with high morbidity and mortality. Piperacillin-tazobactam is a frequently used therapy in critically ill patients with pulmonary infection. Antibiotic concentrations in the lung reflect target site antibiotic concentrations in patients with pneumonia. The aim of this study was to assess the plasma and intra-pulmonary pharmacokinetics (PK) of piperacillin-tazobactam in critically ill patients administered standard piperacillin-tazobactam regimens. A population PK model was developed to describe plasma and intra-pulmonary piperacillin and tazobactam concentrations. The probability of piperacillin exposures reaching pharmacodynamic endpoints and the impact of pulmonary permeability on piperacillin and tazobactam pulmonary penetration was explored. The median piperacillin and tazobactam pulmonary penetration ratio was 49.3% and 121.2%, respectively. Pulmonary piperacillin and tazobactam concentration were unpredictable and negatively correlated to pulmonary permeability. Current piperacillin-tazobactam regimens may be insufficient to treat pneumonia caused by piperacillin-tazobactam susceptible organisms in some critically ill patients. PMID:24926779

    AIM: To investigate the incidence of various types of postoperative pulmonary complications (POPCs) and to evaluate the significance of perioperative arterial blood gases in patients with esophageal cancer accompanied with chronic obstructive pulmonary disease (COPD) after esophagectomy. MEHTODS: Three hundred and fifty-eight patients were divided into POPC group and COPD group. We performed a retrospective review of the 358 consecutive patients after esophagectomy for esophageal cancer with or without COPD to assess the possible influence of COPD on postoperative pulmonary complications. We classified COPD into four grades according to percent-predicted forced expiratory volume in 1 s (FEV1) and analyzed the incidence rate of complications among the four grades. Perioperative arterial blood gases were tested in patients with or without pulmonary complications in COPD group and compared with POPC group. RESULTS: Patients with COPD (29/86, 33.7%) had more pulmonary complications than those without COPD (36/272, 13.2%) (P < 0.001). Pneumonia (15/29, 51.7%), atelectasis (13/29, 44.8%), prolonged O2 supplement (10/29, 34.5%), and prolonged mechanical ventilation (8/29, 27.6%) were the major complications in COPD group. Moreover, patients with severe COPD (gradeIIB, FEV1 < 50% of predicted) had more POPCs than those with moderate(gradeIIA, 50%-80% of predicted) and mild (gradeI≥ 80% of predicted) COPD (P < 0.05). PaO2 was decreased and PaCO2 was increased in patients with pulmonary complications in COPD group in the first postoperative week. CONCLUSION: The criteria of COPD are the critical predictor for pulmonary complications in esophageal cancer patients undergoing esophagectomy. Severity of COPD affects the incidence rate of the pulmonary complication, and percent-predicted FEV1 is a good predictive variable for pulmonary complication in patients with COPD. Arterial blood gases are helpful in directing perioperative management. PMID:16688794

    Introduction Patients who are frail, have multiple comorbidities or have a terminal illness often have poor outcomes from surgery. However, sole specialists may recommend surgery in these patients without consultation with other treating clinicians or allowing for patient goals. The Patient-Centred Advanced Care Planning (PC-ACP) model of care provides a framework in which a multidisciplinary advanced care plan is devised to incorporate high-risk patients' values and goals. Decision-making is performed collaboratively by patients, their family, surgeons, anaesthetists, intensivists and surgical case managers. This study aims to evaluate the feasibility of this new model of care, and to determine potential benefits to patients and clinicians. Methods and analysis After being assessed for frailty, patients will complete a patient–clinician information engagement survey pretreatment and at 6 months follow-up. Patients (and/or family members) will be interviewed about their experience of care pretreatment and at 3 and 6 months follow-ups. Clinicians will complete a survey on workplace attitudes and engagement both preimplementation and postimplementation of PC-ACP and be interviewed, following each survey, on the implementation of PC-ACP. We will use process mapping to map the patient journey through the surgical care pathway to determine areas of improvement and to identify variations in patient experience. Ethics and dissemination This study has received ethical approval from Townsville Hospital and Health Service HREC (HREC/16/QTHS/100). Results will be communicated to the participating hospital, presented at conferences and submitted for publication in a peer-reviewed MEDLINE-indexed journal. PMID:28242771

    The recommendations of the International Task Force for the Prevention of Coronary Heart Disease/International Atherosclerosis Society (ITF/IAS), the US-American Adult Treatment Panel III of the National Cholesterol Education Programs (ATP III) and the 3rd Joint European Guidelines (3JE) for the prevention coronary heart disease (CHD) show good agreement in tertiary prevention. All three guidelines recommend that patients with manifest CHD should have a blood pressure below 140/90 mm Hg and LDL-cholesterol below 2.6 mmol/l (100 mg/dl). By contrast, the three recommendations differ with respect to the prevention of cardiovascular events in asymptomatic high risk patients (secondary prevention), notably in the strategy to be used for risk assessment. Both the ITF/IAS guidelines and the 3JE guidelines can be adapted and realized in the various European countries. We therefore compared the prognostic values of the three recommendations by applying them to the data of male participants of the Prospective Cardiovascular Munster (PROCAM) Study. The ITF/IAS recommendations show the highest specificity (94.5%), positive predictive value (32.0%) and diagnostic efficacy (90.5%); the 3JE guidelines have the highest sensitivity (64.6%) but lowest specificity (77.9%), positive predictive value (17.5%) and diagnostic efficacy (77.0%). The application of the 3JE recommendations would target 25% of German men aged 35-65 years as cardiovascular high risk patients, by contrast to 7.5% through application of the ITF/IAS guidelines. In view of the limited resources in the public health systemthe application of the ITF/IAS guidelines in Germany appears more appropriate.

    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.

    To properly perform preoperative pulmonary rehabilitation is important for lung cancer surgeries in patients with poor pulmonary function such as severe chronic obstructive pulmonary disease( COPD) to prevent postoperative complications. Those programs include exercise training, pursed-lip breathing technique, activities of dairy living training and facilitating physical activities, all which are almost same as those for patients with stable COPD. Pedometer is a useful tool to lead patient's physical activities. Postoperative therapeutic programs are also important, which includes early mobilization, nutritional support, and so on.

Preoperative lung function assessment includes respiratory function tests (RFT) and cardio-pulmonary exercise testing (CPET). Vo2 peak, FEV1 and DLCO as well as recognition of performance status, presence of co-morbidities, frailty indexes, and age predict the potential impact of surgical resection on patient health status and survival risk. In this study we have retrospectively assessed the benefit of a high-intensity preoperative pulmonary rehabilitation program (PRP) in 14 patients with underlying lung function impairment prior to surgery. Amongst these, three patients candidate to surgical resection exhibited severe functional impairment associated with high score of frailty according CHS and SOF index, resulting in a substantial mortality risk. Our observations indicate that PRP appear to reduce the mortality and morbidity risk in frail patients with concurrent lung function impairment undergoing thoracic surgery. PRP produced improvement of VO2 peak degree and pulmonary function resulting in reduced postoperative complications in high-risk patients from our cases. Our results indicate that a preoperative training program may improve postoperative clinical outcomes in fraillung cancer patients with impaired lung function prior to surgical resection.

    Thoracic surgery remains the better therapeutic option for non-small cell lung cancer patients that are diagnosed in early stage disease. Preoperative lung function assessment includes respiratory function tests (RFT) and cardio-pulmonary exercise testing (CPET).

    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.

    Periprocedural management of patients on long-term warfarin therapy remains a common and important clinical issue, with little high-quality data to guide this complex process. The current accepted practice is cessation of warfarin five days preoperatively, but this is not without risk and can be complicated, particularly if bridging is required. An alternative method utilising low-dose intravenous vitamin K the day before surgery has been shown previously to be efficacious, safe and convenient in an elective surgical population receiving chronic warfarin therapy. The efficacy and utility of this 'fast-track' warfarin reversal protocol in surgical patients with cancer, who were at high risk of both thromboembolism and bleeding was investigated in a prospective, single-arm study at a dedicated cancer centre. Seventy-one patients underwent 82 episodes of fast-track warfarin reversal (3 mg intravenous vitamin K 18 to 24 hours before surgery). No patient suffered an adverse reaction to intravenous vitamin K, all but one achieved an International Normalized Ratio =1.5 on the day of surgery, and no surgery was deferred. Assays of vitamin K-dependent factor levels pre- and post-vitamin K demonstrated restoration of functional activity to within an acceptable range for surgical haemostasis. While this alternative method requires further validation in a larger prospective randomised study, we have now extended our use of fast-track warfarin reversal using vitamin K to patients with cancer, on the basis of our experience of its safety, convenience, reliability and efficacy.

    Pulmonary Hypertension (PH) is definited by a mean pulmonary artery pressure (PAPm) >25 mmHg at rest. The Dana Point 2008 Revised Classification System represents the most recent classification system update with respect of various etiologies of PH. About 10 % of adolescents or adults with uncorrected congenital heart disease (CHD) with left-to-right shunt and high pulmonary blood flow develop Pulmonary Arterial Hypertension (PAH) . Progressive vascular remodeling and increase in pulmonary vascular resistance (PVR) may ultimately lead to reversal of the shunt (pulmonary to systemic) causing cyanosis and determining the so-called Eisenmenger Syndrome (ES). Recent advances in the early diagnosis and medical targeted treatment of adult patients with CHD-PAH and ES can improve PAP, PVR and exercise tolerance, together with NYHA Class and survival, and may potentially reverse the vascular remodeling process in selected patients.

    Surgically resected stage III melanoma patients commonly receive adjuvant therapy with interferon (IFN) alpha2b. For those patients with high-risk features of draining node recurrence, radiation therapy can also be considered as a treatment option. The purpose of this retrospective study was to assess the efficacy and radiation-related toxicity of this combined therapy. Eighteen patients receiving adjuvant IFNalpha2b therapy during radiation therapy, or within 1 month of its completion, were reviewed retrospectively and analysed for outcome. Radiation was delivered at 600 cGy dose per fraction, in 16 out of 18 patients, twice a week, and at 200 cGy dose per fraction in two patients five times a week. Total radiation dose and number of fractions were as follows: 30 Gy/5 fr (n=8), 36 Gy/6 fr (n=8) and 50 Gy/25 fr (n=2). The percentage of disease-free patients, with no local recurrence, at 3 years was 88%. In 10 patients, IFNalpha2b was administered concurrently with radiotherapy; in three, within 30 days before or after radiation; and in five, more than 30 days after radiation. All the patients experienced acute skin reactions, grade I on the Radiation Therapy Oncology Group (RTOG) scale. Late radiation-related toxicity was seen in one patient with grade III (RTOG) skin reaction and two with grade IV (RTOG) radiation-induced myelitis. Concurrent use of adjuvant radiotherapy and IFNalpha2b might enhance radiation-induced toxicity, and special care should be taken when the spinal cord is included in the radiation field.

    Objective: The objective of the study was to determine the incidence of postcesarian febrile morbidity and relate this to hospital stay in a high-risk indigent population treated at a private non-teaching hospital.Methods: This was a retrospective chart review of all patients done between January 1995 and December 1996. Discharge summaries, antepartums, progress notes, and labs were reviewed for each patient. Of 257 charts reviewed, 5 were inadequate for various reasons. Board-certified surgeons performed and assisted in the operations. Twenty-one patients had scant prenatal care and 6 had no prenatal care. All patients had the abdomen scrubbed with Betadine soap prior to painting. No shaving was done. Gloves were changed after closure of uterine incision. The pelvis was copiously irrigated with 3-4 L of saline. The subcutaneous layer was irrigated from a height of 6-12" with 12 to 1 L of fluid. After this step, this layer is not touched by anything from the operating field.Results: Of 162 patients with primary cesarian, 20 had postoperative fever, 18 with endometritis, 2 with wound infections. All but 5 of these patients had labor as ruptured membranes of 12 hours or more. Four had prolonged 2nd stage. Of 28 failed VBACs, 2 had fever vs none for 59 elective repeat cesarians. The average hospital stay for febrile patients was 4.4 days vs 2.7 for afebrile patients. The incidence of wound infection was 0.8%. The incidence of fever was 12.2% for primary cesarians and 8.8% in the total study group of 249 patients.Conclusion: This study demonstrates that the adoption of simple measures presented in Methods can dramatically decrease the incidence and severity of postcesarian fever, especially wound infection, thereby allowing safe, early hospital discharge.

    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

    Highly activated/expanded natural killer (NK) cells can be generated by stimulation with the human leukocyte antigen-deficient cell line K562, genetically modified to express 41BB-ligand and membrane-bound interleukin (IL)15. We tested the safety, persistence, and activity of expanded NK cells generated from myeloma patients (auto-NK) or haploidentical family donors (allo-NK) in heavily pretreated patients with high-risk relapsing myeloma. The preparative regimen comprised bortezomib only or bortezomib and immunosuppression with cyclophosphamide, dexamethasone, and fludarabine. NK cells were shipped overnight either cryopreserved or fresh. In 8 patients, up to 1×10⁸ NK cells/kg were infused on day 0 and followed by daily administrations of IL2. Significant in vivo expansion was observed only in the 5 patients receiving fresh products, peaking at or near day 7, with the highest NK-cell counts in 2 subjects who received cells produced in a high concentration of IL2 (500 U/mL). Seven days after infusion, donor NK cells comprised >90% of circulating leukocytes in fresh allo-NK cell recipients, and cytolytic activity against allogeneic myeloma targets was retained in vitro. Among the 7 evaluable patients, there were no serious adverse events that could be related to NK-cell infusion. One patient had a partial response and in another the tempo of disease progression decreased; neither patient required further therapy for 6 months. In the 5 remaining patients, disease progression was not affected by NK-cell infusion. In conclusion, infusion of large numbers of expanded NK cells was feasible and safe; infusing fresh cells was critical to their expansion in vivo.

    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.

    BACKGROUND: A small number of people with chronic obstructive pulmonary disease (COPD) receive pulmonary function testing around the time of diagnosis. Because omitting testing increases misdiagnosis, we sought to determine whether health outcomes differed between patients whose COPD was diagnosed with or without pulmonary function testing. METHODS: We conducted a longitudinal population study of patients with physician-diagnosed COPD from 2005 to 2012 using health administrative data from Ontario, Canada. We assessed whether having pulmonary function testing around the time of diagnosis was associated with the composite outcome of admission to hospital for COPD or all-cause death, using adjusted survival analysis. RESULTS: Chronic obstructive pulmonary disease was diagnosed in 68 898 patients during the study period; 41.2% of patients received peridiagnostic pulmonary function testing. In adjusted analysis, patients who underwent testing were less likely to die or be admitted to hospital for COPD (adjusted hazard ratio [HR] 0.91, 95% confidence interval [CI] 0.89–0.94) and were more likely to be prescribed an inhaled long-acting bronchodilator than patients who did not undergo testing. Subgroup analysis suggested that the association of testing and outcomes was confined to patients with COPD diagnosed in the ambulatory care setting (adjusted HR 0.80, 95% CI 0.76–0.84). INTERPRETATION: Confirmation of a COPD diagnosis using pulmonary function testing is associated with a decreased risk of death and admission to hospital for COPD. In ambulatory patients, this effect may be from increased use of appropriate COPD medications. The findings of this study validate current guideline recommendations that encourage pulmonary function testing for diagnosis in all patients with suspected COPD.

    In a phase I/IIa study of in situ gene therapy using an adenovirus vector carrying the human REIC/Dkk-3 gene (Ad-REIC), we assessed the inhibitory effects of cancer recurrence after radical prostatectomy (RP), in patients with high risk localized prostate cancer (PCa). After completing the therapeutic interventions with initially planned three escalating doses of 1.0 × 10(10) , 1.0 × 10(11) , and 1.0 × 10(12) viral particles (VP) in 1.0-1.2 mL (n = 3, 3, and 6), an additional higher dose of 3.0 × 10(12) VP in 3.6 mL (n = 6) was further studied. Patients with recurrence probability of 35% or more within 5 years after RP as calculated by Kattan's nomogram, were enrolled. They received two ultrasound-guided intratumoral injections at 2-week intervals, followed by RP 6 weeks after the second injection. Based on the findings of MRI and biopsy mapping, as a rule, one track injection to the most prominent cancer area was given to initial 12 patients and 3 track injections to multiple cancer areas in additional 6 patients. As compared to the former group, biochemical recurrence-free survival of the latter showed a significantly favorable outcome. Neoadjuvant Ad-REIC, mediating simultaneous induction of cancer selective apoptosis and augmentation of antitumor immunity, is a feasible approach in preventing cancer recurrence after RP. (199).

    The presence of CD19 in myelomatous plasma cells (MM-PCs) correlates with adverse prognosis in multiple myeloma (MM). Although CD19 expression is upregulated by CD81, this marker has been poorly investigated and its prognostic value in MM remains unknown. We have analyzed CD81 expression by multiparameter flow cytometry in MM-PCs from 230 MM patients at diagnosis included in the Grupo Español de Mieloma (GEM)05>65 years trial as well as 56 high-risk smoldering MM (SMM). CD81 expression was detected in 45% (103/230) MM patients, and the detection of CD81(+) MM-PC was an independent prognostic factor for progression-free (hazard ratio=1.9; P=0.003) and overall survival (hazard ratio=2.0; P=0.02); this adverse impact was validated in an additional series of 325 transplant-candidate MM patients included in the GEM05 <65 years trial. Moreover, CD81(+) SMM (n=34/56, 57%) patients had a shorter time to progression to MM (P=0.02). Overall, our results show that CD81 may have a relevant role in MM pathogenesis and represent a novel adverse prognostic marker in myeloma.

    Knowledge on associations between ultra-high risk (UHR) for developing psychosis and on non-psychotic psychopathology in help-seeking populations is limited with respect to differences between male and female patients. The present study tests the hypothesis that both social anxiety and depression are highly prevalent in an UHR population, particularly among women. From February 2008 to February 2010 baseline data were collected from help-seeking subjects (14-35 years) who were included in the Dutch Early Detection and Intervention Evaluation (EDIE-NL) trial. Two recruiting strategies were used: a two-stage screening strategy in a population of consecutive help-seeking and distressed subjects of secondary mental health services, and a referral strategy. This study included 201 patients with a mean age of 22.7 years. Of these, 102 (51%) were female, 58% of the patients met the criteria for clinical depression on the Beck Depression Inventory and 42% met the criteria for clinical social phobia on the Social Interaction Anxiety Scale. Women showed more depression and social anxiety than men. The results support the hypothesis that UHR is associated with depression and social anxiety, particularly in women. Screening a help-seeking population with depression and anxiety may be effective in detecting patients at UHR for developing psychosis.

    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 outcomes of the physician-patient discussion intervene in the satisfaction of cardiovascular disease risk patients. Adherence to treatment, provision of continuous care, clinical management of the illness and patients’ adjustment are influenced by satisfaction with physician-patient interaction. This study aims to determine the patient satisfaction with doctor-patient interaction and over six months after following prevention counselling, its associations with modifiable cardiovascular risk factors amongst moderately-high risk patients in a primary healthcare clinic in Kelantan, Malaysia. Methods A prospective survey was conducted amongst patients with moderately-high cardiovascular risk. A total of 104 moderately-high risk patients were recruited and underwent structured prevention counselling based on the World Health Organization guideline, and their satisfaction with the doctor-patient interaction was assessed using ‘Skala Kepuasan Interaksi Perubatan-11,’ the Malay version of the Medical Interview Satisfaction Scale-21. Systolic blood pressure, total cholesterol and high-density lipoprotein cholesterol were measured at baseline and at a follow-up visit at six months. Descriptive analysis, paired t test and linear regression analyses were performed. Results A total of 102 patients responded, giving a response rate of 98.1%. At baseline, 76.5% of the respondents were satisfied with the relation with their doctor, with the favourable domain of distress relief (85.3%) and rapport/confidence (91.2%). The unfavourable domain was interaction outcome, with satisfaction in only 67.6% of the respondents. Between the two visits, changes had occurred in total cholesterol (P = 0.022) and in systolic blood pressure (P < 0.001). Six months after the initial visits, no relationship existed between patient satisfaction scores and changes in modifiable cardiovascular risks.

    Background This study examined characteristics of adult and adolescent patients with cystic fibrosis (CF) to determine factors associated with an increased risk of pulmonary exacerbations. Methods 249 patients with CF infected with multidrug resistant bacteria were recruited and prospectively followed for up to 4.5 years until they experienced a pulmonary exacerbation severe enough to require intravenous antibiotics. Multivariable regression analyses were used to compare the characteristics of patients who experienced an exacerbation with those who did not. Results 124 of the 249 patients (50%) developed a pulmonary exacerbation during the first year and 154 (62%) experienced an exacerbation during the 4.5 year study period. Factors predictive of exacerbations in a multivariable survival model were younger age (OR 0.98, 95% CI 0.96 to 0.99), female sex (OR 1.45, 95% CI 1.07 to 1.95), lower forced expiratory volume in 1 second (FEV1) (OR 0.98, 95% CI 0.97 to 0.99), and a previous history of multiple pulmonary exacerbations (OR 3.16, 95% CI 1.93 to 5.17). Chronic use of inhaled corticosteroids was associated with an increased risk of exacerbation (OR 1.92, 95% CI 1.00 to 3.71) during the first study year. Conclusions Patients who experience pulmonary exacerbations are more likely to be younger, female, using inhaled steroids, have a lower FEV1, and a history of multiple previous exacerbations. It is hoped that knowledge of these risk factors will allow better identification and closer monitoring of patients who are at high risk of exacerbations. PMID:16844728

    Background: Vitamin D has a potential to modulate inflammatory response against noxious particles in patients with chronic obstructive pulmonary disease (COPD). The present study was conducted to determine the status of serum vitamin D in COPD versus healthy group. Methods: The patients presented to the outpatient pulmonary clinic of Ayatollah Rouhani Hospital, Babol Iran. Diagnosis of COPD was confirmed based on airflow limitation defined as FEV1/FVC ratio <70% and FEV1< 80% of predicted. All eligible patients aged ≥ 40 years old entered the study. Pulmonary infection, tuberculosis, pleural effusion, congestive heart failure, pulmonary hypertension and embolism, restrictive airway disease, conditions leading changes in vitamin D metabolism and absorption were excluded. Serum 25-hydroxyvitamin D (25-OHD) was determined by electrocheminluminescence method and levels <20, 20-29, and ≥30ng/ml were considered as deficiency, insufficiency, and sufficiency. In statistical analysis, the frequency of serum 25-OHD deficiency and insufficiency in patients were compared regarding age of ≤ 50 or >50 years old. All patients were males and age and sex-matched controls were selected among healthy subjects accompanied COPD patients. Results: Ninety patients and 100 controls with respective mean (±SD) age of 64.8±11.7 and 62.6±11.7 years old (P=0.19) were studied. Compared with control, proportions of serum 25-OHD deficiency and insufficiency in patients >50 years were higher and deficiency was lower (61.5% vs 87.5%, P=0.11). Conclusion: These findings indicate that a significant proportion of young COPD patients have insufficient serum 25-OHD. Regarding a positive relationship between 25-OHD and FEV1 in COPD, these findings highlight serum 25-OHD assessment in COPD for recognizing high risk patients. PMID:26221507

    Gastroccult reagent was used every 4 h to detect blood in gastric juice in 41 ICU patients at risk of GI bleeding (GB) and receiving antacid prophylaxis (gastric pH greater than 3.5). Of the present patients, 27% (11/41) had at least one episode of occult GB (three consecutive positive determinations; a total of 14 episodes). Endoscopy identified acute gastroduodenal mucosal lesions (stress ulcers) as the most frequent lesion in this group (eight patients). Sepsis was the most frequent underlying condition associated with occult GB due to stress ulcer. Hematemesis occurred in 36% (4/11) of patients with occult GB and was due to stress ulcer in three patients and to benign gastric tumor in one. No overt GB occurred in the absence of previous occult GB. We conclude that: a) risk of GB persists in critically ill ICU patients in spite of antacid prophylaxis (gastric pH greater than 3.5); b) high-risk patients can be identified through periodic testing for the presence of blood in gastric juice using the reagent; c) when occult GB occurs, treatment should be based on the endoscopy results. In the absence of acute gastroduodenal mucosal lesions, antacid prophylaxis should not be modified, and specific treatment of the identified lesion(s) should be initiated. In the presence of stress lesions, antacid prophylaxis should be reinforced if the pH of the gastric content is less than 3.5 and a septic complication should be actively sought if the pH is greater than 3.5.

    Background and Purpose Extended-volume external-beam radiation therapy (rt) following esophagectomy is controversial. The present prospective study evaluates the feasibility of extended-volume rt treatment in high-risk esophagectomy patients with a cervical anastomosis receiving postoperative combined chemoradiation therapy. Patients and Methods From 2001 to 2006, 15 patients with resected esophageal cancer were prospectively accrued to this pilot study to evaluate the adverse effects of extended-volume rt. Postoperative management was carried out at London Regional Cancer Program. Eligibility criteria were pathology-proven esophageal malignancy (T3–4, N0–1), disease amenable to surgical resection, and esophagectomy with or without resection margin involvement. Patients with distant metastases (M1) and patients treated with previous rt were excluded. All 15 study patients received 4 cycles of 5-fluorouracil–based chemotherapy. External-beam rt was conducted using conformal computed tomography planning, with multi-field arrangement tailored to the pathology findings, with coverage of a clinical target volume encompassing the primary tumour bed and the anastomotic site in the neck. The radiation therapy dose was 50.40 Gy at 1.8 Gy per fraction. The rt was delivered concurrently with the third cycle of chemotherapy. The study outcomes—disease-free survival (dfs) and overall survival (os)—were calculated by the Kaplan–Meier method. Treatment-related toxicities were assessed using the U.S. National Cancer Institute’s Common Toxicity Criteria. Results The study accrued 10 men and 5 women of median age 64 years (range: 48–80 years) and TNM stages T3N0 (n = 1), T2N1 (n = 2), T3N1 (n = 11), and T4N1 (n = 1). Histopathology included 5 adenocarcinomas and 10 squamous-cell carcinomas. Resection margins were clear in 10 patients. The median follow-up time was 19 months (range: 3.5–53.4 months). Before radiation therapy commenced, delay in chemotherapy occurred

    Background Febrile neutropenia is an important cause of mortality and morbidity in hematology–oncology patients undergoing chemotherapy. The management of febrile neutropenia is typically algorithm-driven. The aim of this study was to assess the results of a standardized protocol for the treatment of febrile neutropenia. Methods A retrospective cohort study (2011–2012) was conducted of patients with high-risk neutropenia in a hematology–oncology service. Results Forty-four episodes of 17 patients with a median age of 48 years (range: 18–78 years) were included. The incidence of febrile neutropenia was 61.4%. The presence of febrile neutropenia was associated with both the duration and severity of neutropenia. Microbiological agents were isolated from different sources in 59.3% of the episodes with bacteremia isolated from blood being the most prevalent (81.3%). Multiple drug-resistant gram-negative bacilli were isolated in 62.5% of all microbiologically documented infections. Treatment of 63% of the episodes in which the initial treatment was piperacillin/tazobactam needed to be escalated to meropenem. The mortality rate due to febrile neutropenia episodes was 18.5%. Conclusion The high rate of gram-negative bacilli resistant to piperacillin/tazobactam (front-line antibiotics in our protocol) and the early need to escalate to carbapenems raises the question as to whether it is necessary to change the current protocol.

    Empirical antifungal therapy is frequently used in hematology patients at high risk of invasive aspergillosis (IA), with substantial cost and toxicity. Biomarkers for IA aim for earlier and more accurate diagnosis and targeted treatment. However, data on the cost-effectiveness of a biomarker-based diagnostic strategy (BDS) are limited. We evaluated the cost effectiveness of BDS using results from a randomized controlled trial (RCT) and individual patient costing data. Data inputs derived from a published RCT were used to construct a decision-analytic model to compare BDS (Aspergillus galactomannan and PCR on blood) with standard diagnostic strategy (SDS) of culture and histology in terms of total costs, length of stay, IA incidence, mortality, and years of life saved. Costs were estimated for each patient using hospital costing data to day 180 and follow-up for survival was modeled to five years using a Gompertz survival model. Treatment costs were determined for 137 adults undergoing allogeneic hematopoietic stem cell transplant or receiving chemotherapy for acute leukemia in four Australian centers (2005-2009). Median total costs at 180 days were similar between groups (US[Formula: see text] for SDS [IQR US[Formula: see text

    Crohn's disease (CD) can be associated with respiratory involvement. Multiple pulmonary nodules are an infrequent finding in patients with CD. When they are found, histology usually shows sterile necrobiotic nodules, which are spherical aggregates of neutrophils, which frequently cavitate. We report a patient with inactive CD treated with mesalazine, who presented with multiple pulmonary nodules. Transthoracic biopsy of one of the nodules disclosed a benign, nongranulomatous inflammatory lymphoid infiltration. The radiographic abnormalities responded well to oral prednisone. Focal, nongranulomatous lymphoid infiltration thus must be considered in the differential diagnosis of multiple pulmonary nodules in patients with CD.

    Hepatic function and pulmonary function are interrelated with failure of one organ system affecting the other. With improved therapies, patients with concomitant hepatic and pulmonary failure increasingly enjoy a good quality of life and life expectancy. Therefore, the prevalence of such patients is increasing with more presenting for both emergent and elective surgical procedures. Hypoxemia requires a thorough evaluation in patients with end-stage liver disease. The most common etiologies respond to appropriate therapy. Portopulmonary hypertension and hepatopulmonary syndrome are associated with increased perioperative morbidity and mortality. It is incumbent on the anesthesiologist to understand the physiology of liver failure and its early effect on pulmonary function to ensure a successful outcome.

    Curcumin (diferuloylmethane), a yellow substance from the root of the plant Curcuma longa Linn., has been demonstrated to inhibit carcinogenesis of murine skin, stomach, intestine and liver. However, the toxicology, pharmacokinetics and biologically effective dose of curcumin in humans have not been reported. This prospective phase-I study evaluated these issues of curcumin in patients with one of the following five high-risk conditions: 1) recently resected urinary bladder cancer; 2) arsenic Bowen's disease of the skin; 3) uterine cervical intraepithelial neoplasm (CIN); 4) oral leucoplakia; and 5) intestinal metaplasia of the stomach. Curcumin was taken orally for 3 months. Biopsy of the lesion sites was done immediately before and 3 months after starting curcumin treament. The starting dose was 500 mg/day. If no toxicity > or = grade II was noted in at least 3 successive patients, the dose was then escalated to another level in the order of 1,000, 2,000, 4,000, 8,000, and 12,000 mg/day. The concentration of curcumin in serum and urine was determined by high pressure liquid chromatography (HPLC). A total of 25 patients were enrolled in this study. There was no treatment-related toxicity up to 8,000 mg/day. Beyond 8,000 mg/day, the bulky volume of the drug was unacceptable to the patients. The serum concentration of curcumin usually peaked at 1 to 2 hours after oral intake of crucumin and gradually declined within 12 hours. The average peak serum concentrations after taking 4,000 mg, 6,000 mg and 8,000 mg of curcumin were 0.51 +/- 0.11 microM, 0.63 +/- 0.06 microM and 1.77 +/- 1.87 microM, respectively. Urinary excretion of curcumin was undetectable. One of 4 patients with CIN and 1 of 7 patients with oral leucoplakia proceeded to develop frank malignancies in spite of curcumin treatment. In contrast, histologic improvement of precancerous lesions was seen in 1 out of 2 patients with recently resected bladder cancer, 2 out of 7 patients of oral leucoplakia, 1 out

    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

    Prediction of psychosis in patients at clinical high risk (CHR) has become a mainstream focus of clinical and research interest worldwide. When using CHR instruments for clinical purposes, the predicted outcome is but only a probability; and, consequently, any therapeutic action following the assessment is based on probabilistic prognostic reasoning. Yet, probabilistic reasoning makes considerable demands on the clinicians. We provide here a scholarly practical guide summarising the key concepts to support clinicians with probabilistic prognostic reasoning in the CHR state. We review risk or cumulative incidence of psychosis in, person-time rate of psychosis, Kaplan-Meier estimates of psychosis risk, measures of prognostic accuracy, sensitivity and specificity in receiver operator characteristic curves, positive and negative predictive values, Bayes' theorem, likelihood ratios, potentials and limits of real-life applications of prognostic probabilistic reasoning in the CHR state. Understanding basic measures used for prognostic probabilistic reasoning is a prerequisite for successfully implementing the early detection and prevention of psychosis in clinical practice. Future refinement of these measures for CHR patients may actually influence risk management, especially as regards initiating or withholding treatment.

    To assess the pre-study, null hypothesis that there is no difference in the electrocardiogram (EKG) findings for Emergency Department (ED) patients who rule in vs. rule out for suspected pulmonary embolism, a retrospective review of a cohort of patients with pulmonary embolism and their controls was conducted in an academic, suburban ED. Patients who were evaluated in the ED during a one-year study period for symptoms suggestive of pulmonary embolism were eligible for inclusion. All patients with pulmonary embolism and sex- and age-matched controls comprised the final study groups. Two board-certified cardiologists reviewed each patient's EKG. There were 350 eligible patients identified; 49 patients with pulmonary embolism and 49 controls were entered into the study. The most common rhythm observed in both groups was normal sinus rhythm (67.3% cases vs. 68.6 % controls; p = 1.0). Abnormalities believed to be associated with pulmonary embolism occurred with similar frequency in both case and control groups (sinus tachycardia [18.8 % vs. 11.8%, respectively; p = 0.40]), incomplete right bundle branch block (4.2% vs. 0.0%, respectively; p = 0.24), complete right bundle branch block (4.2% vs. 6.0, respectively; p = 1.0), S1Q3T3 pattern (2.1 vs. 0.0, respectively; p = 0.49), S1Q3 pattern (0.0 vs. 0.0), and extreme right axis (0.0 vs. 0.0). New EKG changes were identified more frequently for patients with pulmonary embolism (33.3% vs. 12.5% controls; p = 0.03), but specific findings were rarely different between cases and controls. In our cohort of ED patients, we did not identify EKG features that are likely to help distinguish patients with pulmonary embolism from those who rule out for the disease.

    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

    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.

    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

    The article contains consideration of risk factors of pulmonary hypertension (PH), clinical states associated with PH, and effect of age on susceptibility to PH in patients with chronic obstructive pulmonary disease (COPD). We have analyzed the prevalence of PH associated with COPD, its importance in the structure of diseases in patients of older age groups. Frequency of PH in old patients is associated with prevalence of concomitant diseases. Addition of LH to polymorbid complex of old age worsens quality of life and increases mortality. We also present in this article data on the use of modern drugs for the treatment of LH in COPD patients aged 60 years and older.

    The Toll-like receptor (TLR) 7/8 agonist resiquimod has been used as an immune adjuvant in cancer vaccines. We evaluated the safety and immunogenicity of the cancer testis antigen NY-ESO-1 given in combination with Montanide (Seppic) with or without resiquimod in patients with high-risk melanoma. In part I of the study, patients received 100 μg of full-length NY-ESO-1 protein emulsified in 1.25 mL of Montanide (day 1) followed by topical application of 1,000 mg of 0.2% resiquimod gel on days 1 and 3 (cohort 1) versus days 1, 3, and 5 (cohort 2) of a 21-day cycle. In part II, patients were randomized to receive 100-μg NY-ESO-1 protein plus Montanide (day 1) followed by topical application of placebo gel [(arm A; n = 8) or 1,000 mg of 0.2% resiquimod gel (arm B; n = 12)] using the dosing regimen established in part I. The vaccine regimens were generally well tolerated. NY-ESO-1-specific humoral responses were induced or boosted in all patients, many of whom had high titer antibodies. In part II, 16 of 20 patients in both arms had NY-ESO-1-specific CD4⁺ T-cell responses. CD8⁺ T-cell responses were only seen in 3 of 12 patients in arm B. Patients with TLR7 SNP rs179008 had a greater likelihood of developing NY-ESO-1-specific CD8⁺ responses. In conclusion, NY-ESO-1 protein in combination with Montanide with or without topical resiquimod is safe and induces both antibody and CD4⁺ T-cell responses in the majority of patients; the small proportion of CD8⁺ T-cell responses suggests that the addition of topical resiquimod to Montanide is not sufficient to induce consistent NY-ESO-1-specific CD8⁺ T-cell responses.

DC-IE consisted of: dexamethasone (days 1-4); cyclophosphamide (day 5); idarubicin and etoposide (days 8-10). Complete response (CR) was achieved in four patients, six patients achieved near complete responses (nCR) and 21 patients achieved a partial remission (PR). Overall response rate was 76% (CI 56-94%) for newly diagnosed patients (n = 21) and 62% (CI 36-81%) for relapsed/refractory patients (n = 24). Toxicities were limited to myelosuppression; two patients died of sepsis during neutropenia (4%). DC-IE is active and tolerable for high-risk multiple myeloma, including patients with relapsed or refractory disease to anthracycline containing regimens.

    Cardiovascular disease is the major cause of morbidity and premature death in most European populations. Due to its prominent role as a risk factor for cardiovascular mortality, lowering of low density lipoprotein cholesterol (LDL-C) levels is the main goal for management of dyslipidemia. To evaluate lipid profiles and management of high risk patients with hyperlipidemia, we performed an observational study in 20 Austrian Departments of Medicine specialized in cardiology, diabetes and/or metabolism from July 2006 to February 2007. Out of 9152 patients [age (mean +/- SD): women 69 +/- 13, men 65 +/- 12 years) 6838 were considered at "very high risk" (group 1; LDL-C: 99 +/- 38 mg/dl) and 2314 at "high risk" (group 2; LDL-C: 108 +/- 39 mg/dl), respectively. Of 4886 patients on statins, 48% of did not reach their LDL-C goals (<70 mg/dl and <100 mg/dl for group 1 and 2, respectively). In 68% of these patients statin therapy was not intensified subsequently. Among patients without lipid-lowering drugs at study entry, 62% did not meet their targets, and despite treatment in the center 1555 of these patients (58%) remained without medication. With regard to national and international guidelines, there is still a need to improve the clinical practice of lowering LDL-C for secondary prevention in high risk patients in Austria.

    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.

There is no 'gold-standard' for the diagnosis of latent TB prior to initiation of biologic agents. We report our own experience of comparing two interferon gamma release assays (IGRAs) in screening for latent TB in a 'high-risk' TB area in patients with rheumatic disorders. The study demonstrated good concordance between the two tests. We believe the additional cost of these assays is justified in high-risk populations prior to biologic agents, with 16% of the current study population with at least one positive IGRA assay.

    Deep abdominal vein thrombosis is extremely rare among thrombotic events secondary to the use of contraceptives. A case to illustrate the clinical utility of ethno-specific pharmacogenetic testing in warfarin management of a Hispanic patient is reported. A 37-year-old Hispanic Puerto Rican, non-gravid female with past medical history of abnormal uterine bleeding on hormonal contraceptive therapy was evaluated for abdominal pain. Physical exam was remarkable for unspecific diffuse abdominal tenderness, and general initial laboratory results—including coagulation parameters—were unremarkable. A contrast-enhanced computed tomography showed a massive thrombosis of the main portal, splenic, and superior mesenteric veins. On admission the patient was started on oral anticoagulation therapy with warfarin at 5 mg/day and low-molecular-weight heparin. The prediction of an effective warfarin dose of 7.5 mg/day, estimated by using a recently developed pharmacogenetic-guided algorithm for Caribbean Hispanics, coincided with the actual patient’s warfarin dose to reach the international normalized ratio target. We speculate that the slow rise in patient’s international normalized ratio observed on the initiation of warfarin therapy, the resulting high risk for thromboembolic events, and the required warfarin dose of 7.5 mg/day are attributable in some part to the presence of the NQO1*2 (g.559C>T, p.P187S) polymorphism, which seems to be significantly associated with resistance to warfarin in Hispanics. By adding genotyping results of this novel variant, the predictive model can inform clinicians better about the optimal warfarin dose in Caribbean Hispanics. The results highlight the potential for pharmacogenetic testing of warfarin to improve patient care. PMID:28210634

    CONTEXT Abstinence-only education has had little demonstrable impact on teenagers’ sexual behaviors, despite significant policy and funding efforts. Given the struggle over resources to improve teenagers’ reproductive health outcomes, the views of clinicians serving teenagers at high risk for unintended pregnancy and STDs merit particular attention. METHODS In 2005, a qualitative study with 31 clinicians serving low-income, at-risk patients was conducted. A semistructured interview guide was used to ask clinicians about adolescent pregnancy, HIV and STD prevention counseling, and when they include abstinence. Thematic content analysis was used to examine the content of the counseling and the techniques used in different situations. RESULTS Providers reported offering comprehensive counseling, presenting abstinence as a choice for teenagers, along with information about contraceptives and condoms. Several providers mentioned that with young, sexually inexperienced teenagers, they discuss delaying sexual activity and suggest other ways to be affectionate, while giving information on condoms. Providers explained how they assess whether teenagers feel ready to be sexually active and try to impart skills for healthy relationships. Some described abstinence as giving teenagers a way to opt out of unwanted sexual activity. Many support abstinence if that is the patient’s desire, but routinely dispense condoms and contraceptives. CONCLUSIONS Overall, providers did not give abstinence counseling as a rigid categorical concept in their preventive practices, but as a health tool to give agency to teenagers within a harm reduction framework. Their approach may be informative for adolescent policies and programs in the future. PMID:20618752

    Purpose Analytically validated assays to interrogate biomarker status in clinical samples are crucial for personalized medicine. PTEN is a tumor suppressor commonly inactivated in prostate cancer that has been mechanistically linked to disease aggressiveness. Though deletion of PTEN, as detected by cumbersome fluorescence in situ hybridization (FISH) spot counting assays, is associated with poor prognosis, few studies have validated immunohistochemical (IHC) assays to determine whether loss of PTEN protein is associated with unfavorable disease. Experimental Design PTEN IHC was validated by employing formalin fixed and paraffin embedded isogenic human cell lines containing or lacking intact PTEN alleles. PTEN IHC was 100% sensitive and 97.8% specific for detecting genomic alterations in 58 additional cell lines. PTEN protein loss was then assessed on 376 prostate tumor samples, and PTEN FISH or high resolution SNP microarray analysis was performed on a subset of these cases. Results PTEN protein loss, as assessed as a dichotomous IHC variable, was highly reproducible, correlated strongly with adverse pathologic features (e.g. Gleason score and pathological stage), detected between 75% and 86% of cases with PTEN genomic loss, and was found at times in the absence of apparent genomic loss. In a cohort of 217 high risk surgically treated patients, PTEN protein loss was associated with decreased time to metastasis. Conclusions These studies validate a simple method to interrogate PTEN status in clinical specimens and support the utility of this test in future multi-center studies, clinical trials and ultimately perhaps for routine clinical care.

    Assessment of clinical outcomes such as 30-day mortality following coronary revascularization procedures has historically been used to spur quality improvement programs. Public reporting of risk-adjusted outcomes is already mandated in several states, and proposals to further expand public reporting have been put forward as a means of increasing transparency and potentially incentivizing high quality care. However, for public reporting of outcomes to be considered a useful surrogate of procedural quality of care, several prerequisites must be met. First, the reporting measure must be truly representative of the quality of the procedure itself, rather than be dominated by other underlying factors, such as the overall level of illness of a patient. Second, to foster comparisons among physicians and institutions, the metric requires accurate ascertainment of and adjustment for differences in patient risk profiles. This is particularly relevant for high-risk clinical patient scenarios. Finally, the potential deleterious consequences of public reporting of a quality metric should be considered prior to expanding the use of public reporting more broadly. In this viewpoint, the authors review in particular the characterization of high-risk patients currently treated by percutaneous coronary interventional procedures, assessing the adequacy of clinical risk models used in this population. They then expand upon the limitations of 30-day mortality as a quality metric for percutaneous coronary intervention, addressing the strengths and limitations of this metric, as well as offering suggestions to enhance its future use in public reporting.

    Objective To show how segmentation can enhance risk stratification tools for integrated care, by providing insight into different care usage patterns within the high-risk population. Design A retrospective cohort study. A risk score was calculated for each person using a logistic regression, which was then used to select the top 5% high-risk individuals. This population was segmented based on the usage of different care settings using a k-means cluster analysis. Data from 2008 to 2011 were used to create the risk score and segments, while 2012 data were used to understand the predictive abilities of the models. Setting and participants Data were collected from administrative data sets covering primary and secondary care for a random sample of 300 000 English patients. Main measures The high-risk population was segmented based on their usage of 4 different care settings: emergency acute care, elective acute care, outpatient care and GP care. Results While the risk strata predicted care usage at a high level, within the high-risk population, usage varied significantly. 4 different groups of high-risk patients could be identified. These 4 segments had distinct usage patterns across care settings, reflecting different levels and types of care needs. The 2008–2011 usage patterns of the 4 segments were consistent with the 2012 patterns. Discussion Cluster analyses revealed that the high-risk population is not homogeneous, as there exist 4 groups of patients with different needs across the care continuum. Since the patterns were predictive of future care use, they can be used to develop integrated care programmes tailored to these different groups. Conclusions Usage-based segmentation augments risk stratification by identifying patient groups with different care needs, around which integrated care programmes can be designed. PMID:27993905

    Background Platelet-rich plasma (PRP) is a human plasma product enriched by platelets, growth factors, and fibrinogen with high hemostatic and healing properties. Objectives The aim of this study was to evaluate the effect of autologous PRP on wound healing in high-risk women undergoing cesarean sections. Patients and Methods In this balanced, randomized, and controlled trial, 140 patients were admitted to Arash women’s hospital, Tehran, Iran from May of 2013 to November of 2014 for elective cesarean surgery. The patients were randomly assigned into two groups. The intervention group received PRP after surgery, whereas the control group received the usual care. All patients were evaluated at baseline, five days, and eight weeks after the cesarean section. The primary endpoint used the REEDA scale for assessing the changes in wound healing. The secondary outcome measures used were the Vancouver scar scale (VSS) and the visual analog scale (VAS). All scale scores were analyzed using a repeated measures test for variance. Results At the end of study, the PRP group showed a greater reduction in the edema ecchymosed discharge approximation (REEDA) score compared to the control group (85.5% reduction in the PRP group; 72% in the control group) (P < 0.001). Compared with the control group, the PRP group had a significantly greater reduction in the VAN score, beginning on the fifth day after the cesarean section (-0.7, 38% reduction in PRP group; -0.8, 33% in control group) (P < 0.001), and this trend was stable at the end of the eighth week (-0.6, 54% reduction in PRP group; -0.3, 18% in control group). Furthermore, patients treated with PRP experienced a 93% reduction in the VAS score at the end of follow-up, but the control group only observed a 79% reduction (P < 0.001). Conclusions It seems that applying PRP is an effective therapeutic approach for wound healing, and faster wound healing is expected due to the presence of more platelets and growth factors. PMID

    Background Hypertension, with a global prevalence of 40%, is a risk factor for cardiovascular diseases (CVD). We conducted an exploratory study in Zhejiang China to understand the prevention of CVD among hypertensive patients with a 10 year CVD risk of 20% or higher. We assessed current practices in a rural ‘township hospital’ (a primary care facility), and compared them with international evidence-based practice. Methods A questionnaire survey was conducted to examine the use of modern drugs (antihypertensive drugs, statins and aspirin) and traditional drugs, compliance to medications and lifestyle among 274 hypertensive patients aged 40-74, with a CVD risk of 20% or higher (using the Asian Equation). Results The majority (72%) were diagnosed with hypertension at township hospitals. Only 15% of study participants used two anti-hypertensive drugs, 0.7% took statin and 2.9% aspirin. Only 2.9% combined two types of modern drugs, while 0.4% combined three types (antihypertensives, statins and aspirin). Herbal compounds, sometimes with internationally rarely recommended drugs such as Reserpine were taken by 44%. Analysis of drug adherence showed that 9.8% had discontinued their drug therapy by themselves. 16% had missed doses and these were on less anti-hypertensive drugs than those who did not (t=-5.217, P=0.003). Of all participants, 28% currently smoked, 39% drank regularly and only 21% exercised frequently. The average salt intake per day was 7.1 (±3.8) g, while the national recommended level is 6g. Conclusion The study revealed outdated and inadequate treatment and health education for hypertensive patients, especially for those who have high risk scores for CVD. There is a need to review the community-based guidelines for hypertension management. Health providers and patients should make a transition from solely treating hypertension, towards prevention of CVD. Health system issues need addressing including improving rural health insurance cover and primary

    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

    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

    The diagnosis of Toxoplasma infection or disease in hematopoietic stem cell transplantation (HSCT) patients is achieved mainly by PCR screening; however screening did not find wide field of use in practice due to costly expenditures of PCR. This study aimed to determine patients at high risk of Toxoplasma infection or disease before transplantation by stem cell originated buffy coat PCR and subsequently to screen them. Buffy coats collected from 12 autologous and 18 allogeneic HSCT patients' donors were investigated by PCR before transplantation. After transplantation, blood and sera collected at fixed time intervals were screened by two PCR methods and serological assays. Screening results first time assessed a toxoplasmosis incidence level as 25% in autologous HSCT patients and increased incidence level in allogeneic HSCT patients to 22%. Importantly, buffy coat PCR was first time performed before transplantation, to determine the risk of toxoplasmosis. Buffy coat PCR results showed that four patients were at high risk of toxoplasmosis before transplantation. After transplantation, these patients experienced toxoplasmosis. In conclusion, for the determination of patients at risk of toxoplasmosis, clinicians should consider buffy coat PCR in combination with serology before transplantation. After transplantation, PCR screening can be initiated in high risk patients upon clinical suspicion.

  17. Targeting patients for multimorbid care management interventions: the case for equity in high-risk patient identification

    PubMed Central

    2013-01-01

    Targeting patients for multimorbid care management interventions requires accurate and comprehensive assessment of patients’ need in order to direct resources to those who need and can benefit from them the most. Multimorbid patient selection is complicated due to the lack of clear criteria - unlike disease management programs for which patients with a specific condition are identified. This ambiguity can potentially result in inequitable selection, as biases in selection may differentially affect patients from disadvantaged population groups. Patient selection could in principal be performed in three ways: physician referral, patient screening surveys, or by statistical prediction algorithms. This paper discusses equity issues related to each method. We conclude that each method may result in inequitable selection and bias, such as physicians’ attentiveness or familiarity, or prediction models’ reliance on prior resource use, potentially affected by socio-cultural and economic barriers. These biases should be acknowledged and dealt with. We recommend combining patient selection approaches to achieve high care sensitivity, efficiency and equity. PMID:23962231

    Patients identified as high risk for postoperative nausea and vomiting (PONV) are often treated prophylactically with intravenous (IV) ondansetron and an additional agent. Limited options exist for a second agent with no adverse effects. The purpose of this investigation was to determine if combining the prophylactic inhalation of isopropyl alcohol (IPA) vapors, an agent with no adverse effects, with IV ondansetron would be more effective than IV ondansetron alone in the prevention of PONV in high-risk patients. A total of 76 patients at high risk for PONV were randomized into control (n = 38) and experimental (n = 38) groups. All patients received IV ondansetron before emergence from general anesthesia. In addition, the experimental group inhaled IPA vapors before induction. Severity of PONV was measured using a 0 to 10 verbal numeric rating scale. Other measured variables included time to onset and incidence of PONV, 24-hour composite nausea score, and satisfaction with nausea control. No significant differences in demographics, surgical or anesthesia time, number of risk factors, severity or incidence of PONV, or satisfaction scores were noted. Prophylactic inhalation of IPA vapors in combination with IV ondansetron was no more efficacious than IV ondansetron alone in the prevention of PONV in a high-risk population.

    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: Leveraging “big data” as a means of informing cost-effective care holds potential in triaging high-risk heart failure (HF) patients for interventions within hospitals seeking to reduce 30-day readmissions. Objective: Explore provider’s beliefs and perceptions about using an electronic health record (EHR)-based tool that uses unstructured clinical notes to risk-stratify high-risk heart failure patients. Methods: Six providers from an inpatient HF clinic within an urban safety net hospital were recruited to participate in a semistructured focus group. A facilitator led a discussion on the feasibility and value of using an EHR tool driven by unstructured clinical notes to help identify high-risk patients. Data collected from transcripts were analyzed using a thematic analysis that facilitated drawing conclusions clustered around categories and themes. Results: From six categories emerged two themes: (1) challenges of finding valid and accurate results, and (2) strategies used to overcome these challenges. Although employing a tool that uses electronic medical record (EMR) unstructured text as the benchmark by which to identify high-risk patients is efficient, choosing appropriate benchmark groups could be challenging given the multiple causes of readmission. Strategies to mitigate these challenges include establishing clear selection criteria to guide benchmark group composition, and quality outcome goals for the hospital. Conclusion: Prior to implementing into practice an innovative EMR-based case-finder driven by unstructured clinical notes, providers are advised to do the following: (1) define patient quality outcome goals, (2) establish criteria by which to guide benchmark selection, and (3) verify the tool’s validity and reliability. Achieving consensus on these issues would be necessary for this innovative EHR-based tool to effectively improve clinical decision-making and in turn, decrease readmissions for high-risk patients.

    As no long-term results of a blind opening up of the pulmonary valve either by balloon valvoplasty or closed Brock valvotomy have been published, we examined the outcome of 12 patients with valvar pulmonary stenosis 17 +/- 5 (11-22) years after surgery. The Brock valvotomy had been carried out at a mean age of 3 +/- 2.8 (0.2-8.5) years. The mean pressure gradient across the right ventricular outflow tract had been 116 +/- 45 (75-97) mmHg at the catheter study or 106 +/- 43 (40-160) mmHg as measured intraoperatively. The right ventricular pressure after the Brock procedure was measured in the operating room in five patients as 46 +/- 15 (30-60) mmHg. Seven patients had been recatheterized at a mean age of 9.5 +/- 2 (7-12.7) years; at that time the gradient across the pulmonary valve had been 20 +/- 14 (10-37) mmHg. At a mean age of 21.7 +/- 3 (15-26) years these and five further patients were reexamined by echo Doppler. This time the pressure gradient across the pulmonary valve was 13 +/- 6 (7-20) mmHg. Moderate pulmonary incompetence was present in four and mild incompetence in eight patients; two had mild tricuspid insufficiency. All except one patient, who had suffered a cerebrovascular accident before surgery, were in NYHA functional class 1 and pursuing a profession. From these data we conclude that the blind opening-up of the pulmonary valve achieves excellent long-term palliation.

  3. Careful counseling is required for patients with pulmonary disease.

    1984-11-01

    Patients with asthma, cystic fibrosis, and other pulmonary diseases require careful family planning counseling. The asmatic patient should be given a birth control method that does not affect the disease or interfere with asthma medications. Oral contraceptives (OCs) are not contraindicated in asthmatic patients, although they may produce rhinitis symptoms. It is possible that the antiinflammatory action of steroids taken by asthmatics may decrease IUD effectiveness. Pregnancy can be a significant risk for patients with cystic fibrosis. In terms of contraception, there is concern that progesterone may cause bronchial mucus to thicken. Methods such as foam, the diaphragm, and condoms are preferred. An IUD can be offered to the patient who must avoid pregnancy due to poor cardiopulmonary status. It should be noted that pulmonary exacerbations of asthma and cystic fibrosis could potentially be confused with a pulmonary embolism.

    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

    Although intra-aortic balloon pumping (IABP) has been used widely as a routine cardiac assist device for perioperative support in coronary artery bypass grafting (CABG), the optimal timing for high-risk patients undergoing first-time CABG using IABP is unknown. The purpose of this investigation is to compare preoperative and preventative IABP insertion with intraoperative or postoperative obligatory IABP insertion in high-risk patients undergoing first-time CABG. We reviewed our IABP patients' database from 2002 to 2007; there were 311 CABG patients who received IABP treatment perioperatively. Of 311 cases, 41 high-risk patients who had first-time on-pump or off-pump CABG (presenting with three or more of the following criteria: left ventricular ejection fraction less than 0.45, unstable angina, CABG combined with aneurysmectomy, or left main stenosis greater than 70%) entered the study. We compared perioperatively the clinical results of 20 patients who underwent preoperative IABP placement (Group 1) with 21 patients who had obligatory IABP placement intraoperatively or postoperatively during CABG (Group 2). There were no differences in preoperative risk factors, except left ventricular aneurysm resection, between the two groups. There were no differences in indications for high-risk patients between the two groups. The mean number of grafts was similar. There were no significant differences in the need for inotropes, or in cerebrovascular, gastrointestinal, renal, and infective complications postoperatively. There were no IABP-related complications in either group. Major adverse cardiac event (severe hypotension and/or shock, myocardial infarction, and severe hemodynamic instability) was higher in Group 2 (14 [66.4%] vs. 1 [5%], P < 0.0001) during surgery. The time of IABP pumping in Group 1 was shorter than in Group 2 (72.5 +/- 28.9 h vs. 97.5 +/- 47.7 h, P < 0.05). The duration of ventilation and intensive care unit stay in Group 1 was significantly shorter

    During a recent one-year period, 44 clinical centers in the United States saw 2,539 patients with diagnoses of pulmonary embolism as supported by high probability lung scans and/or positive pulmonary angiograms. In developing proposals for a clinical trial of Thrombolysis in Pulmonary Embolism (TIPE), investigators in the 44 clinical centers reviewed the 2,539 patients' medical charts for contraindications to thrombolytic therapy. Overall, 1,345 (53.5%) patients surveyed in the TIPE clinical centers would have been acceptable for treatment with thrombolytic therapy, a proportion higher than generally anticipated. Risks of major blood loss were the most frequent contraindications to thrombolytic therapy and were found in 838 (33.3%) patients. Risks to the CNS were found to contraindicate thrombolytic therapy in 453 (17.9%) patients. Risks of bleeding into special compartments were found to contraindicate thrombolytic therapy in 76 (3.0%) patients. Pulmonary embolism is underdiagnosed in most clinical settings, and even more patients than found in the TIPE survey could benefit from appropriate diagnosis and treatment. The question remains as to whether pulmonary embolism patients will benefit from thrombolytic therapy. Only a randomized clinical trial will provide a satisfactory answer.

    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.

    Pulmonary hypertension (PH) is a common complication of chronic pulmonary diseases, especially in advanced disease, and is associated with greater mortality and worse clinical course. Patients with symptoms that exceed those expected by their pulmonary disease should be further evaluated by echocardiography. Confirmatory right heart catheterization is indicated in those conditions where the results of the hemodynamic assessment will determine treatment options. The treatment of choice for patients who are hypoxemic and have pulmonary hypertension associated with chronic lung disease is long-term oxygen therapy. Conventional vasodilators or drugs approved for pulmonary arterial hypertension are not recommended in patients with mild-to-moderate PH because they may impair gas exchange and because there is a lack of evidence supporting their efficacy. Patients with severe PH should be considered for referral to a center with expertise in PH and lung diseases. Ideally, these patients should be included in randomized controlled trials to determine which patients are more likely to derive benefit and which therapies are most likely to be successful.

    A critical review of various high risk situations in which neuroleptics could be used and have been used in clinical practice is presented. These high risk situations include: women of child bearing age (pregnant women, lactating and/or nursing mothers), the two extremes of life (children and the elderly), patients with sexual dysfunction, patients with tardive dyskinesia, non-psychotic psychiatric patients, physically ill and suicidal patients. The extraordinary applications of these drugs, such as for rapid tranquilization and megadose regimens are examined. The author provides guidelines for the use of neuroleptics in these clinical situations.

  10. Pulmonary Hypertension in Heart Failure Patients: Pathophysiology and Prognostic Implications.

    PubMed

    Guazzi, Marco; Labate, Valentina

    2016-12-01

    Pulmonary hypertension (PH) due to left heart disease (LHD), i.e., group 2 PH, is the most common reason for increased pressures in the pulmonary circuit. Although recent guidelines incorporate congenital heart disease in this classification, left-sided heart diseases of diastolic and systolic origin including valvular etiology are the vast majority. In these patients, an increased left-sided filling pressure triggers a multistage hemodynamic evolution that ends into right ventricular failure through an initial passive increase in pulmonary artery pressure complicated over time by pulmonary vasoconstriction, endothelial dysfunction, and remodeling of the small-resistance pulmonary arteries. Regardless of the underlying left heart pathology, when present, PH-LHD is associated with more severe symptoms, worse exercise tolerance, and outcome, especially when right ventricular dysfunction and failure are part of the picture. Compared with group 1 and other forms of pulmonary arterial hypertension, PH-LHD is more often seen in elderly patients with a higher prevalence of cardiovascular comorbidities and most, if not all, of the features of metabolic syndrome, especially in case of HF preserved ejection fraction. In this review, we provide an update on current knowledge and some potential challenges about the pathophysiology and established prognostic implications of group 2 PH in patients with HF of either preserved or reduced ejection fraction.

    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.

    Background Due to the lack of specific clinical manifestations and imaging features, the diagnosis of pulmonary mycosis is difficult. This study aimed to investigate the pathogens, clinical manifestations, imaging features, diagnosis and management of pulmonary mycosis. Methods Data on 68 patients diagnosed as pulmonary mycosis in Xiang Ya hospital from January 2001 to December 2010 were collected and their clinical manifestations, radiographic characterization, diagnostic methods and management were analyzed. Results All patients were diagnosed by pathological examination. Of the 68 cases, 38 (55.9%) had pulmonary aspergillosis and 19 (27.9%) pulmonary cryptococcosis. Open-lung surgery was performed in 38 patients (55.9%), transbronchial biopsy in 15 (22.0%), and computerized tomography (CT) guided percutaneous needle biopsy in 11 (16.2%). Main symptoms were as follows: cough in 51 cases (75.0%), expectoration in 38 (55.9%), hemoptysis in 25 (37.8%), fever in 20 (29.4%), while 6 cases (11.1%) were asymptomatic. X-ray and chest CT showed masses or nodular lesions in 52 cases (76.5%), patchy lesions in 10 (14.7%), cavity formation in 15 (22.0%), and diffuse miliary nodules in 1 case. In 51 cases (75.0%) misdiagnosis before pathological examination occurred. Surgical resection was performed in 38 patients (55.9%). In 25 patients (36.7%) systemic antifungal therapy was administered, and 20 patients (29.4%) experienced complete responses or partial responses. Conclusion The main pathogens of pulmonary mycosis are Aspergillus, followed by cryptococcosis. Final diagnosis of pulmonary mycosis mainly depends on pathological examination. The clinical manifestations, imaging features, diagnostic methods and management differ depending on the pathogens. Satisfactory therapy can be obtained by both antifungal and surgical treatment.

    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.

    Aspirin use for primary prevention in patients at high risk with diabetes mellitus (DM) is often recommended under the assumption that most patients with DM have coronary artery disease (CAD). However, not all patients may have CAD. The present study evaluated, in 425 patients at high risk with DM (without chest pain syndrome or a history of cardiac disease), the prevalence of CAD on coronary computed tomography angiography (CTA). Moreover, the association between the presence and number of traditional cardiovascular (CV) risk factors and CAD (on coronary CTA) was evaluated. The median coronary artery calcium score was 29 (interquartile range 0 to 298). On coronary CTA, 116 patients (27%) had no CAD (defined as <30% stenosis). Of the 309 patients (73%) with any CAD (≥30% stenosis), 35% had obstructive CAD (≥50% stenosis). The number of traditional CV risk factors was not associated with the presence of any CAD (≥30% stenosis; p = 0.18) or obstructive CAD (≥50% stenosis; p = 0.13). Hypertension was the only traditional CV risk factor associated with a higher frequency of any CAD (≥30% stenosis; odds ratio = 2.21, 95% CI 1.43 to 3.41, p <0.001) and obstructive CAD (≥50% stenosis; odds ratio 2.03, 95% CI 1.33 to 3.11, p = 0.001). In conclusion, in patients at high risk with DM without chest pain syndrome, any CAD was ruled out by coronary CTA in 27%, whereas 65% of the patients did not have obstructive CAD. The number of CV risk factors was not associated with the presence of CAD. Hypertension was the only traditional CV risk factor that was associated with a higher frequency of CAD. These observations support potential use of coronary CTA to tailor aspirin therapy in patients at high risk with DM.

    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.).

    Recently, small case series have described the successful off-label use of transcatheter valve implantation in patients with degenerated bioprosthetic valves in the mitral position. We report here the case of a 78-year old female patient who underwent transcatheter aortic valve implantation for severe aortic stenosis and transapical valve-in-valve implantation for a degenerated mitral bioprosthesis. There was no evidence of intraprosthetic regurgitation and/or paraprosthetic leakages on control angiography and transoesophageal echocardiography. The postoperative course was uneventful. Following accurate patient selection and evaluation by an experienced multidisciplinary team, the transcatheter approach to double-valve implantation in the aortic and mitral positions may represent a viable treatment option for those high-risk patients who would otherwise be inoperable. We preferred a two-step approach, considering a single procedure to be high-risk.

  17. The influence of preoperative risk stratification on fast-tracking patients after pulmonary resection.

    Fast-tracking protocols or postoperative care computerized algorithms have been shown to reduce hospital length of stay and reduce costs; however, not all patients can be fast-tracked. Certain patient characteristics may put patients at increased risk to fail fast-tracking. Additionally some patients have multiple risk factors that have an additive effect that puts them at an even increased risk to fail fast-tracking, and more importantly, to significant morbidity. It is a mistake to force these protocols on all patients because it can lead to increased complications, readmissions, and low patient and family satisfaction. By carefully analyzing surgical results via accurate prospective databases, the types of patients who fail fast-tracking and the reasons they fail can be identified. Once these characteristics are pinpointed, specific changes to the postoperative algorithm can be implemented, and these alterations can lead to improved outcomes. The authors have shown that by using pain pumps instead of epidurals in elderly patients we can improve outcomes and still fast-track octogenarians with minimal morbidity and high-patient satisfaction. We have also shown that the increased use of physical therapy and respiratory treatments (important parts of the care of all patients after pulmonary resection, but a limited resource in most hospitals) may also lead to improved surgical results for those who have low FEV1% and DLco%. Further studies are needed. Although fast-tracking protocols cannot be applied to all, the vast majority of patients who undergo elective pulmonary resection, even those at high risk, can undergo safe, efficient, and cost-saving care via preset postoperative algorithms. When the typical daily events are convened each morning and the planned date of discharge is frequently communicated with the patient and family before surgery and each day in the hospital, most patients can be safely fast-tracked with high satisfaction and outstanding results.

    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.

    2016-01-01

    While the guidelines for breast cancer screening in average-risk women are well established, screening in high-risk women is not as clear. For women with BRCA1 or BRCA2 mutations, current guidelines recommend screening by clinical breast examination and mammography starting at age 30. For certain high-risk women, additional screening with magnetic resonance imaging (MRI) is encouraged. This review focuses on differentiating imaging modalities used for screening women at high-risk for breast cancer over the age of 50 by discussing the different imaging techniques, cost versus benefit, detection rates, and impact on survival. While mammography is the only imaging modality proven to reduce mortality from breast cancer, MRI is more sensitive in identifying cancers. MRI can often identify smaller malignancies at a greater resolution at an earlier stage. The use of MRI would be more cost effective as there would be less need for invasive therapeutic procedures. Research thus far has not identified an age-specific preference in imaging modality. There are no guidelines for high-risk women that specify screening with respect to age (i.e., older than 50 years old). More research is needed before screening guidelines in different age groups with various risk factors can be established. PMID:28133583

    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.

    Purpose The role of adjuvant chemoradiotherapy (ACRT) or adjuvant chemotherapy (ACT) in treating patients with locally advanced upper rectal cancer (URC) after total mesorectal excision (TME) surgery remains unclear. We developed a clinical nomogram and a recursive partitioning analysis (RPA)-based risk stratification system for predicting 5-year cancer-specific survival (CSS) to determine whether these individuals require ACRT or ACT. Materials and Methods This retrospective analysis included 547 patients with primary URC. A nomogram was developed based on the Cox regression model. The performance of the model was assessed by concordance index (C-index) and calibration curve in internal validation with bootstrapping. RPA stratified patients into risk groups based on their tumor characteristics. Results Five independent prognostic factors (age, preoperative increased carcinoembryonic antigen and carcinoma antigen 19-9, positive lymph node [PLN] number, tumor deposit [TD], pathological T classification) were identified and entered into the predictive nomogram. The bootstrap-corrected C-index was 0.757. RPA stratification of the three prognostic groups showed obviously different prognosis. Only the high-risk group (patients with PLN ≤ 6 and TD, or PLN > 6) benefited from ACRT plus ACT when compared with surgery followed by ACRT or ACT, and surgery alone (5-year CSS: 70.8% vs. 57.8% vs. 15.6%, P < 0.001). Conclusions Our nomogram predicts 5-year CSS after TME surgery for locally advanced rectal cancer and RPA-based stratification indicates that ACRT plus ACT post-surgery may be an important treatment plan with potentially significant survival advantages in high-risk URC. This may help to select candidates of adjuvant treatment in prospective studies. PMID:27449095

    Abstract Rationale: Pulmonary veno-occlusive disease (PVOD) is a rare form of pulmonary arterial hypertension (PAH). Oral anticoagulation is confined to patients with idiopathic PAH (IPAH), but no oral anticoagulation has been recommended for PVOD, because occult pulmonary hemorrhage was a common finding in PVOD. Patient concerns: We report a case of PVOD, who was misdiagnosed as IPAH for 5 years with worsening dyspnea and two episodes of pulmonary embolism (PE). Diagnoses: He was confirmed as PVOD combined with PE by biopsy of the explanted lung specimen. Interventions: He took oral anticoagulation, warfarin, to treat his first-time PE in July 2010, and his disease was kept stable for about 4 years, until he discontinued the anticoagulation therapy by himself sometime in 2014. Later on, a life-threatening PE recurred in January 2015, so he resumed the anticoagulation therapy. Outcomes: Fortunately, the bilateral sequential lung transplantation that was performed in July 2015 in time saved his life. He has been living well without dyspnea and the echocardiography showed the normalizations of the once increased pulmonary arterial pressure and the once enlarged right ventricle of his heart. In addition, to the best of my knowledge, he was the first PVOD patient receiving lung transplantation in China. Lessons: We recommend that PVOD patients combined with PE should be treated with anticoagulation therapy indefinitely to prevent the recurrence of life-threatening PE until they get a chance for lung transplantation.

    BACKGROUND/AIMS—Fellow eye prophylaxis for retinal detachment (RD) is still a controversial issue since opinions are not unanimous regarding the kind of lesions to be treated or the method of treatment. This prospective clinical study aimed to follow the course of vitreoretinal conditions in 150 high risk fellow eyes.
METHODS—150 consecutive patients with unilateral rhegmatogenous RD were included in this study. Inclusion criteria were good explorability of fellow eye retinal periphery and one of the following conditions in the fellow eye—aphakia, pseudophakia with capsulotomy, high myopia (>−6D), contralateral eye to a giant retinal tear. Prophylactic treatment (photocoagulation or scleral buckling) was performed in the presence of retinal tears and lattice degenerations. The state of the vitreous body was determined at the beginning of the study and at the end, when RD occurred.
RESULTS—Follow up ranged from 36 to 132 months. 95 fellow eyes were subjected to laser treatment; five eyes underwent prophylactic surgical treatment. Initially, in the treated group posterior vitreous detachment (PVD) was present in 100 eyes (100% of cases), but as a complete PVD only in 42 of them (42%). 10 eyes in the treated group developed RD during the follow up period. In five of these cases the partial PVD had progressed and a retinal tear in a previously healthy area was the cause of the retinal detachment. In the other five eyes RD apparently developed from previously treated lesions. Progression of PVD was evident in four out of these five eyes. The untreated eyes had no visible degenerative lesions. During follow up eight eyes developed RD. These eyes had no PVD at the beginning of the study, but showed a partial PVD at the time of the diagnosis of RD.
CONCLUSION—Fellow eyes with pre-existing retinal tears and PVDs can go on to retinal detachment in spite of laser prophylactic treatment. When PVD is not detectable or a partial PVD is present, the

    The study aimed to prospectively evaluate correlations between dynamic contrast-enhanced (DCE) MR perfusion imaging, pulmonary function tests (PFT) and volume quantitative CT in smokers with or without chronic obstructive pulmonary disease (COPD) and to determine the value of DCE-MR perfusion imaging and CT volumetric imaging on the assessment of smokers. According to the ATS/ERS guidelines, 51 male smokers were categorized into five groups: At risk for COPD (n = 8), mild COPD (n = 9), moderate COPD (n = 12), severe COPD (n = 10), and very severe COPD (n = 12). Maximum slope of increase (MSI), positive enhancement integral (PEI), etc. were obtained from MR perfusion data. The signal intensity ratio (RSI) of the PDs and normal lung was calculated (RSI = SIPD/SInormal). Total lung volume (TLV), total emphysema volume (TEV) and emphysema index (EI) were obtained from volumetric CT data. For "at risk for COPD," the positive rate of PDs on MR perfusion images was higher than that of abnormal changes on non-enhanced CT images (p < 0.05). Moderate-to-strong positive correlations were found between all the PFT parameters and SIPD, or RSI (r range 0.445∼0.683, p ≤ 0.001). TEV and EI were negatively correlated better with FEV1/FVC than other PFT parameters (r range -0.48 --0.63, p < 0.001). There were significant differences in RSI and SIPD between "at risk for COPD" and "very severe COPD," and between "mild COPD" and "very severe COPD". Thus, MR perfusion imaging may be a good approach to identify early evidence of COPD and may have potential to assist in classification of COPD.

    Background: Ibrutinib is an active therapy with an acceptable safety profile for patients with chronic lymphocytic leukemia (CLL), including high-risk patients with del17p or with TP53 mutations. Ibrutinib is broadly indicated for the treatment of patients with CLL and specifically including those with 17p deletion. The optimal use of ibrutinib in combination with other agents remains controversial.Methods: We report the long-term outcome [median follow-up of 47 months (range, 36-51 months)] of 40 patients with high-risk CLL, treated on the first ibrutinib combination trial with rituximab (IR). The majority of patients (36/40) were previously treated.Results: Median age was 65 years, and 21 patients (52%) had 17p deletion. Median duration on treatment was 41 months (range, 2-51 months), and median number of treatment cycles was 42 (range, 2-49). Overall response rate was 95%, and 9 patients (23%) attained a complete remission. Twenty-one patients discontinued treatment, 10 due to disease progression, 9 for other causes, and 2 due to stem cell transplantation; the remaining 19 patients continue on ibrutinib. Median progression-free survival for all patients was 45 months, which was significantly shorter in the subgroup of patients with del17p (n = 21, 32.3 months, P = 0.02). Fourteen patients (35%) died, five from progressive disease, five from infections, and four from other causes. Median overall survival has not been reached.Conclusions: IR combination therapy leads to durable remissions in high-risk CLL; the possible benefit from the addition of rituximab is currently explored in a randomized trial.

    Objective The aim of this study was to evaluate the biochemical recurrence (BCR) in patients with high-risk prostate cancer (PCa) treated with radical prostatectomy (RP) or radiotherapy (RT) plus androgen deprivation therapy (ADT). Methods Subjects were patients with National Comprehensive Cancer Network-defined high-risk PCa treated with either RP or RT plus ADT. We calculated BCR-free survival in patients with those treatments and evaluated risk factor against BCR. Results A total of 114 patients, 71 RP and 43 RT plus ADT, were evaluated. A total of 59 and 20.9% of patients experienced BCR in the RP and RT treatment groups, respectively. The 5-year BCR-free survival probabilities improved significantly for patients who received RT compared to those who received RP (81.3 vs 37.3%, P<0.001). According to the number of risk factors, 59.2% of patients in the RP and 51.2% of patients in the RT treatment groups were classified with one risk factor (P<0.014). The 5-year BCR-free survival probabilities for patients treated with RP were 46.6 and 21.7% for one and multiple risk factors, respectively (P=0.008). On univariate analysis, only the number of risk factors had a significant impact on the risk of BCR. Meanwhile, there were no significant differences in the 5-year BCR-free survival probabilities between one and multiple risk factors in patients treated with RT. Conclusion Among patients treated with RP, a marked heterogeneity existed in the oncological outcomes. Based on these findings, the number of risk factors should be emphasized to decide the optimal treatments for patients with high-risk PCa. PMID:27981044

    The role of adjuvant hormonal therapy and optimized regimens for high-risk localized prostate cancer after radical prostatectomy remains controversial. Herein, the clinical trial CU1005 prospectively evaluated two regimens of maximum androgen blockage  or bicalutamide 150 mg daily as immediate adjuvant therapy for high-risk localized prostate cancer. Overall, 209 consecutive patients were recruited in this study, 107 of whom received 9 months of adjuvant maximum androgen blockage, whereas 102 received 9 months of adjuvant bicalutamide 150 mg. The median postoperative follow-up time was 27.0 months. The primary endpoint was biochemical recurrence. Of the 209 patients, 59 patients developed biochemical recurrence. There was no difference between the two groups with respect to clinical characteristics, including age, pretreatment prostate-specific antigen, Gleason score, surgical margin status, or pathological stages. The maximum androgen blockage group experienced longer biochemical recurrence-free survival (P = 0.004) compared with the bicalutamide 150 mg group. Side-effects in the two groups were similar and could be moderately tolerated in all patients. In conclusion, immediate, 9-month maximum androgen blockage should be considered as an alternative to bicalutamide 150 mg as adjuvant treatment for high-risk localized prostate cancer patients after radical prostatectomy.

    Idiopathic pulmonary arterial hypertension (IPAH) is associated with proliferation of smooth muscle cells (SMCs) in small pulmonary arteries. Inhibition of proliferation of pulmonary artery smooth muscle cells (PASMCs) may be an effective treatment of patients with idiopathic pulmonary arterial hypertension. Recent studies have shown that carvedilol, an alpha- and beta-blocker with antioxidant and calcium channel blocking properties, inhibits the proliferation of cultured normal human pulmonary artery smooth muscle cells. In this study, we tested the hypothesis that carvedilol has antiproliferative effects on pulmonary artery smooth muscle cells of patients with idiopathic pulmonary arterial hypertension. Pulmonary artery smooth muscle cells from six idiopathic pulmonary arterial hypertension patients who had undergone lung transplantation were cultured. To determine cell proliferation, H-thymidine incorporation was measured. Platelet-derived growth factor-induced proliferation of IPAH-PASMCs was significantly greater than that of normal control pulmonary artery smooth muscle cells. Carvedilol (0.1 microM to 10 microM) inhibited the proliferation of idiopathic pulmonary arterial hypertension-pulmonary artery smooth muscle cells in a concentration-dependent manner. Prazosin (an alpha-blocker) and N-acetyl L cysteine (an antioxidant agent) (0.1 microM to 10 microM) did not inhibit their proliferation, but the high concentration of propranolol (a beta-blocker) and nifedipine (a calcium channel blocker) (10 microM) inhibited the proliferation. The combination of propranolol and nifedipine inhibited the proliferation but only at a high concentration (10 microM) combination. Cell cycle analysis revealed that carvedilol (10 microM) significantly decreased the number of cells in S and G2/M phases. These results indicate that carvedilol inhibits the exaggerated proliferation of pulmonary artery smooth muscle cells of patients with idiopathic pulmonary arterial hypertension

    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

    The automatic ICD improves survival in patients with a history of sudden cardiac arrest. However, some patients do not meet the guidelines for ICD implantation or are unable to receive an implantable device. This study tested the hypothesis that these patients could benefit from a wearable cardioverter defibrillator. Patients with symptomatic heart failure and an ejection fraction of <0.30 (WEARIT Study) or patients having complications associated with high risk for sudden death after a myocardial infarction or bypass surgery not receiving an ICD for up to 4 months (BIROAD Study) were enrolled into two studies. After a total of 289 patients had been enrolled in the trial (177 in WEARIT and 112 in BIROAD), prespecified safety and effectiveness guidelines had been met. Six (75%) of eight defibrillation attempts were successful. Six inappropriate shock episodes occurred during 901 months of patient use (0.67% unnecessary shocks per month of use). Twelve deaths occurred during the study 6 sudden deaths: 5 not wearing and 1 incorrectly wearing the device). Most patients tolerated the device although 68 patients quit due to comfort issues or adverse reactions. The results of the present study suggest that a wearable defibrillator is beneficial in detecting and effectively treating ventricular tachyarrhythmias in patients at high risk for sudden death who are not clear candidates for an ICD and may be useful as a bridge to transplantation or ICD in some patients.

    Purpose Cure rates for localized high-risk prostate cancers (PCa) and some intermediate-risk PCa are frequently suboptimal with local therapy. Outcomes are improved by concomitant androgen-deprivation therapy (ADT) with radiation therapy, but not by concomitant ADT with surgery. Luteinizing hormone–releasing hormone agonist (LHRHa; leuprolide acetate) does not reduce serum androgens as effectively as abiraterone acetate (AA), a prodrug of abiraterone, a CYP17 inhibitor that lowers serum testosterone (< 1 ng/dL) and improves survival in metastatic PCa. The possibility that greater androgen suppression in patients with localized high-risk PCa will result in improved clinical outcomes makes paramount the reassessment of neoadjuvant ADT with more robust androgen suppression. Patients and Methods A neoadjuvant randomized phase II trial of LHRHa with AA was conducted in patients with localized high-risk PCa (N = 58). For the first 12 weeks, patients were randomly assigned to LHRHa versus LHRHa plus AA. After a research prostate biopsy, all patients received 12 additional weeks of LHRHa plus AA followed by prostatectomy. Results The levels of intraprostatic androgens from 12-week prostate biopsies, including the primary end point (dihydrotestosterone/testosterone), were significantly lower (dehydroepiandrosterone, Δ4-androstene-3,17-dione, dihydrotestosterone, all P < .001; testosterone, P < .05) with LHRHa plus AA compared with LHRHa alone. Prostatectomy pathologic staging demonstrated a low incidence of complete responses and minimal residual disease, with residual T3- or lymph node–positive disease in the majority. Conclusion LHRHa plus AA treatment suppresses tissue androgens more effectively than LHRHa alone. Intensive intratumoral androgen suppression with LHRHa plus AA before prostatectomy for localized high-risk PCa may reduce tumor burden. PMID:25311217

    Background Laparoscopic cholecystectomy in acute calculous cholecystitis in high risk patients can lead to significant morbidity and mortality. Percutaneous cholecystostomy may be an alternative treatment option but the current literature does not provide the surgical community with evidence based advice. Methods/Design The CHOCOLATE trial is a randomised controlled, parallel-group, superiority multicenter trial. High risk patients, defined as APACHE-II score 7-14, with acute calculous cholecystitis will be randomised to laparoscopic cholecystectomy or percutaneous cholecystostomy. During a two year period 284 patients will be enrolled from 30 high volume teaching hospitals. The primary endpoint is a composite endpoint of major complications within three months following randomization and need for re-intervention and mortality during the follow-up period of one year. Secondary endpoints include all other complications, duration of hospital admission, difficulty of procedures and total costs. Discussion The CHOCOLATE trial is designed to provide the surgical community with an evidence based guideline in the treatment of acute calculous cholecystitis in high risk patients.

    Background. Perception remains that brachytherapy-based regimens are inappropriate for patients having increased risk of extracapsular extension (ECE). Methods. 321 consecutive intermediate and high-risk disease patients were treated between 1/92 and 2/97 by one author (M. Dattoli) and stratified by NCCN guidelines. 157 had intermediate-risk; 164 had high-risk disease. All were treated using the combination EBRT/brachytherapy ± hormones. Biochemical failure was defined using PSA >0.2 and nadir +2 at last followup. Nonfailing patients followup was median 10.5 years. Both biochemical data and original biopsy slides were independently rereviewed at an outside institution. Results. Overall actuarial freedom from biochemical progression at 16 years was 82% (89% intermediate, 74% high-risk) with failure predictors: Gleason score (P = .01) and PSA (P = .03). Hormonal therapy did not affect failure rates (P = .14). Conclusion. This study helps to strengthen the rationale for brachytherapy-based regimens as being both durable and desirable treatment options for such patients. Prospective studies are justified to confirm these positive results.

    JAK2/STAT signaling promotes survival and expansion of myelodysplastic syndrome (MDS) clones, but little is known about the potential of JAK2/STAT as a therapeutic target in MDS. We investigated the effect of NS-018, a novel antagonist for JAK2, on the colony-forming ability of bone marrow mononuclear cells (BMMNCs) from high-risk MDS patients. NS-018 decreased colony-forming unit-granulocyte/macrophage (CFU-GM) colony numbers from MDS-derived BMMNCs in a dose-dependent manner, and this effect was significantly more potent than against normal BMMNCs. In addition, NS-018 suppressed the phosphorylation of STAT3 in colony-forming cells from MDS patients. Collectively, NS-018 could be a new therapeutic option for high-risk MDS.

    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.

    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.

    Accumulating evidence suggests that altered cellular metabolism is systemic in pulmonary hypertension (PH) and central to disease pathogenesis. However, bioenergetic changes in PH patients and their association with disease severity remain unclear. Here, we hypothesize that alteration in bioenergetic function is present in platelets from PH patients and correlates with clinical parameters of PH. Platelets isolated from controls and PH patients (n = 28) were subjected to extracellular flux analysis to determine oxygen consumption and glycolytic rates. Platelets from PH patients showed greater glycolytic rates than controls. Surprisingly, this was accompanied by significant increases in the maximal capacity for oxygen consumption, leading to enhanced respiratory reserve capacity in PH platelets. This increased platelet reserve capacity correlated with mean pulmonary artery pressure, pulmonary vascular resistance, and right ventricular stroke work index in PH patients and was abolished by the inhibition of fatty acid oxidation (FAO). Consistent with a shift to FAO, PH platelets showed augmented enzymatic activity of carnitine palmitoyltransferase-1 and electron transport chain complex II. These data extend the observation of a metabolic alteration in PH from the pulmonary vascular axis to the hematologic compartment and suggest that measurement of platelet bioenergetics is potentially useful in assessment of disease progression and severity.

    Postoperative pulmonary complications (PPCs) are one of the most important causes of postoperative morbidity and mortality after abdominal surgery. Although chronic obstructive pulmonary disease (COPD) has been considered a risk factor for PPCs, it remains unclear whether mild-to-moderate COPD is a risk factor. This retrospective cohort study included 387 subjects who underwent abdominal surgery with general anesthesia in a tertiary referral hospital. PPCs included pneumonia, pulmonary edema, pulmonary thromboembolism, atelectasis, and acute exacerbation of COPD. Among the 387 subjects, PPCs developed in 14 (12.0%) of 117 patients with mild-to-moderate COPD and in 13 (15.1%) of 86 control patients. Multiple logistic regression analysis revealed that mild-to-moderate COPD was not a significant risk factor for PPCs (odds ratio [OR] =0.79; 95% confidence interval [CI] =0.31–2.03; P=0.628). However, previous hospitalization for respiratory problems (OR =4.20; 95% CI =1.52–11.59), emergency surgery (OR =3.93; 95% CI =1.75–8.82), increased amount of red blood cell (RBC) transfusion (OR =1.09; 95% CI =1.05–1.14 for one pack increase of RBC transfusion), and laparoscopic surgery (OR =0.41; 95% CI =0.18–0.93) were independent predictors of PPCs. These findings suggested that mild-to-moderate COPD may not be a significant risk factor for PPCs after abdominal surgery. PMID:27877032

    The 133Xe ventilation studies, 99mTc perfusion lung images, and pulmonary angiograms of 83 patients with obstructive pulmonary disease and suspected pulmonary emboli were reviewed. Each patient had ventilation abnormalities suggesting OPD and at least one region showing matched V-P abnormalities. All angiograms were obtained within 72 hours of the V-P study and were reviewed independently. The overall sensitivity of V-P imaging for PE in this population was 0.83 and its specificity was 0.92. False-negative interpretations occurred in three of the 16 patients who showed ventilation abnormalities in more than 50% of their lung fields. In the 67 patients with ventilation abnormalities in less than or equal to 50% of their lung fields the sensitivity and specificity for detecting PE were high, V-P imaging is a reliable method for detecting PE in patients with regions of V-P match, if the ventilation abnormalities are limited in extent.

    Patients with idiopathic pulmonary fibrosis (IPF) have significantly impaired pulmonary diffusion, which may affect the pulmonary concentration of many drugs, including antibiotics. In this study, we compared the difference in pulmonary levofloxacin (LVFX) concentration between patients with normal lung function and IPF. The IPF group included 10 patients with a proven diagnosis of IPF and a diffusing capacity for carbon monoxide ranging from 40% to 70% of predicted values. The control group included 10 patients with normal pulmonary function. Blood and bronchoalveolar lavage fluid (BALF) were taken at 3-3.5 h after fasting. LVFX (500 mg) was administered orally. LVFX concentrations in the serum and BALF were determined using HPLC-MS/MC. The level of LVFX in alveolar epithelial lining fluid (ELF) was calculated using the following formula: LVFX ELF = LVFX BALF × (Urea serum/Urea BALF). No significant differences in age, body weight, height, and calculated creatinine clearance and BALF retrieval rate were observed between groups. LVFX serum concentrations in the IPF and control groups were (5.97 ± 1.28) μg/ml and (6.84 ± 3.43) μg/ml, respectively (P = 0.4727). ELF concentration of LVFX in the control group was (27.81 ± 21.36) μg/ml, while the concentration in the IPF group was (10.17 ± 2.46) μg/ml, less than half of that in the controls (P = 0.0058). The intrapulmonary concentration of LVFX in IPF patients was lower than those with normal lung function. Notably, however, the ELF LVFX concentration following 500 mg once-daily exceeded the MIC90 of common respiratory pathogens. Excellent antibacterial efficacy of LVFX can be expected for IPF patients in the treatment of respiratory tract infections.

    The purpose of the present study was to analyze genetic variations in the NBS1 gene and to evaluate the contribution of heterozygous NBS1 mutation to the risk of breast cancer among Korean patients with high-risk breast cancer negative for BRCA1/2 mutation. We screened 235 non-BRCA1/2 Korean patients with high-risk breast cancer for NBS1 mutations. The entire NBS1 gene was sequenced using fluorescent conformation-sensitive capillary electrophoresis. In silico analysis of the NBS1 variants was performed using PolyPhen-2 and SIFT. The frequency of variants predicted to be deleterious by in silico analysis was compared between breast cancer patients and controls. Twenty-eight sequence variants in the NBS1 gene were identified: 9 exonic variants, including 5 missense mutations (p.R169C, p.I171V, p.E185Q, p.E564K, and p.F603L) and 4 silent mutations, and 19 variants within introns. Among the five missense variants, p.I171V (c.511A > G) was the only variant predicted to be deleterious by in silico analysis. Heterozygosity for p.I171V was found in 4/235 patients with breast cancer and 3/281 individuals in the control group. The frequency of p.I171V was not significantly different between the patient and control groups (1.7 vs. 1.06%, p = 0.7). Heterozygosity of p.I171V in the NBS1 gene was found in a small proportion of Korean patients with high-risk breast cancer. The contribution of the p.I171V variant to the development of breast cancer among Korean patients was not significant.

    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

    Outcome of patients with primary refractory/relapsed (R/R) acute myeloid leukemia (AML) remains dismal. Herein, we present a retrospective monocentric study of 24 very high-risk AML patients who received a combination of fractionated gemtuzumab ozogamicin (GO) with intermediate-dose cytarabine and daunorubicin as salvage therapy. Median age was 55.3 years. Diagnostic was secondary AML for 33% of them. Seven patients had favorable risk, 8 had intermediate-1 or intermediate-2, and 6 had unfavorable risk of AML according to the European LeukemiaNet prognostic index. Complete remission was achieved in 50% of cases (46% in refractory and 55% in relapsed AML) without excessive toxicity. Thirteen patients could be referred for transplant. Only allogeneic hematopoietic stem cell transplantation provided a benefit in this patient cohort with a 1-year overall survival of 50.7 versus 18.1% in the absence of transplantation. Patients treated with reduced intensity conditioning (RIC) showed a longer survival as compared to those undergoing myeloablative conditioning regimen mainly because of decreased toxicity.Our data suggest that salvage therapy with fractionated GO combined with intermediate-dose cytarabine and daunorubicin in very high-risk patients may serve as a potential bridge therapy to RIC transplant.

    The diagnosis or exclusion of pulmonary embolism (PE) remains challenging for emergency physicians. Symptoms can be vague or non-existent, and the clinical presentation shares features with many other common diagnoses. Diagnostic testing is complicated, as biomarkers, like the D-dimer, are frequently false positive, and imaging, like computed tomography pulmonary angiography, carries risks of radiation and contrast dye exposure. It is therefore incumbent on emergency physicians to be both vigilant and thoughtful about this diagnosis. In recent years, several advances in treatment have also emerged. Novel, direct-acting oral anticoagulants make the outpatient treatment of low risk PE easier than before. However, the spectrum of PE severity varies widely, so emergency physicians must be able to risk-stratify patients to ensure the appropriate disposition. Finally, PE response teams have been developed to facilitate rapid access to advanced therapies (e.g., catheter directed thrombolysis) for patients with high-risk PE. This review will discuss the clinical challenges of PE diagnosis, risk stratification and treatment that emergency physicians face every day. PMID:27752629

    OBJECTIVE: To evaluate the role of right heart catheterization in the diagnosis of pulmonary arterial hypertension (PAH). METHODS: We evaluated clinical, functional, and hemodynamic data from all patients who underwent right heart catheterization because of diagnostic suspicion of PAH-in the absence of severe left ventricular dysfunction (LVD), significant changes in pulmonary function tests, and ventilation/perfusion lung scintigraphy findings consistent with chronic pulmonary thromboembolism-between 2008 and 2013 at our facility. RESULTS: During the study period, 384 patients underwent diagnostic cardiac catheterization at our facility. Pulmonary hypertension (PH) was confirmed in 302 patients (78.6%). The mean age of those patients was 48.7 years. The patients without PH showed better hemodynamic profiles and lower levels of B-type natriuretic peptide. Nevertheless, 13.8% of the patients without PH were categorized as New York Heart Association functional class III or IV. Of the 218 patients who met the inclusion criteria, 40 (18.3%) and 178 (81.7%) were diagnosed with PH associated with LVD (PH-LVD) and with PAH, respectively. The patients in the HP-LVD group were significantly older than were those in the PAH group (p < 0.0001). CONCLUSIONS: The proportional difference between the PAH and PH-LVD groups was quite significant, considering the absence of echocardiographic signs suggestive of severe LVD during the pre-catheterization investigation. Our results highlight the fundamental role of cardiac catheterization in the diagnosis of PAH, especially in older patients, in whom the prevalence of LVD that has gone undiagnosed by non-invasive tests is particularly relevant.

    Clinical trials are evaluating the effect of neoadjuvant chemotherapy on men with high-risk prostate cancer. Little is known about the clinical significance of postchemotherapy tumor histopathologic features. We assessed the prognostic and predictive value of histologic features (intraductal carcinoma, vacuolated cell morphologic features, inconspicuous glands, cribriform architecture, and inconspicuous cancer cells) observed in 50 high-risk prostate cancers treated with preprostatectomy docetaxel and mitoxantrone. At a median follow-up of 65 months, the overall relapse-free survival (RFS) rates at 2 and 5 years were 65% and 49%, respectively. In univariate analyses (using the Kaplan-Meier method and log-rank tests), intraductal (P = .001) and cribriform (P = .014) histologic features were associated with shorter RFS. In multivariate analyses, using the Cox proportional hazards regression, baseline prostate-specific antigen (P = .004), lymph node metastases (P < .001), and cribriform histologic features (P = .007) were associated with shorter RFS. In multivariable logistic regression analysis, only intraductal pattern (P = .007) predicted lymph node metastases. Intraductal and cribriform histologic features apparently predict postchemotherapy outcome.

    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

    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

    The ancillary analysis of the KYOTO HEART Study (n = 3031) was designed to assess the combined treatment with calcium channel blocker (CCB) plus valsartan for high-risk hypertension. With-CCB (n = 1807) showed less primary events than without-CCB (n = 1224) (P = .037), in which acute myocardial infarction was significantly reduced. With-CCB plus valsartan (n = 773) showed lower incidence than with-CCB plus non-angiotensin receptor blocker (ARB) (n = 1034) (P = .0002), in which angina pectoris and heart failure were significantly reduced. Without-CCB plus valsartan (n = 744) was superior to without-CCB plus non-ARB (n = 480) (P = .0013), in which stroke was reduced. CCB-based therapy was useful, and CCB plus valsartan combination provided a more efficient prevention for high-risk hypertensive patients.

    This study investigated if improvements can be maintained over 24 weeks when in-home pulmonary telerehabilitation is combined with asynchronous self-management education for Chronic Obstructive Pulmonary Disease (COPD). Twenty-three community-living elders with moderate to very severe COPD participated in a pre/post-intervention study. Over 8 weeks, they had access to self-learning capsules on self-management, received 15 in-home teletreatment sessions and were encouraged to gradually engage in unsupervised sessions. Participants were assessed before the intervention (T1), immediately after the intervention (T2), and 6 months later (T3). Outcome measures were (1) exercise tolerance (6-minute walk test [6MWT]), Cycle Endurance Test [CET]), and (2) quality of life (Chronic Respiratory Questionnaire [CRQ]). Although there were significant improvements after 8 weeks of pulmonary telerehabilitation on the 6MWT, CET and three of four CRQ domains, none of these improvements were maintained after 6 months and scores returned to their baseline values (all p values > 0.05 when comparing T3 with T1). While pulmonary telerehabilitation is possible and has a positive impact on patients with moderate to very severe COPD, improvements were not maintained in the long-term even when physical therapy was accompanied by self-management education.

    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

    A seventy-four-year-old patient had lupus vulgaris associated with the nodular, confluent ulcerated type of pulmonary tuberculosis. The diagnosis had been missed on several occasions. The presence of cutaneous tuberculosis in developed countries is emphasized again. It is also stressed that chronic dermatosis of unknown nature in an immunocompetent patient may have a tubercular origin. Complete resolution of the disease was achieved after almost two years of anti-tubercular therapy.

    Terminal chronic obstructive pulmonary disease (COPD) and advanced cancer have similar prognosis and symptom burden. However, palliative care of patients with terminal COPD has been neglected in Denmark. We describe the symptoms of terminal COPD and suggest criteria for defining the palliative phase of the disease. Furthermore we discuss the prognostic and ethical challenges for patients, their families and their caregivers. Finally, we summarize the current evidence for palliative treatment of dyspnoea and ways to evaluate response to treatment.

    Pulmonary Arterial Hypertension (PAH) is a rare and progressive disease with low incidence and prevalence, and elevated mortality. PAH is characterized by increased mean pulmonary artery pressure. The aim of this study was to analyse patients with combined mutations in BMPR2, ACVRL1, ENG and KCNA5 genes and to establish a genotype-phenotype correlation. Major genes were analysed by polymerase chain reaction (PCR) and direct sequencing. Genotype-phenotype correlation was performed. Fifty-seven (28 idiopathic PAH, 29 associated PAH group I) were included. Several mutations in different genes, classified as pathogenic by in silico analysis, were present in 26% of PAH patients. The most commonly involved gene was BMPR2 (12 patients) followed by ENG gene (9 patients). ACVRL1 and KCNA5 genes showed very low incidence of mutations (5 and 1 patients, respectively). Genotype-phenotype correlation showed statistically significant differences for gender (p = 0.045), age at diagnosis (p = 0.035), pulmonary vascular resistance (p = 0.030), cardiac index (p = 0.035) and absence of response to treatment (p = 0.011). PAH is consequence of a heterogeneous constellation of genetic arrangements. Patients with several pathogenic mutations seem to display a more severe phenotype. PMID:27630060

    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

    In clinical practice, respiratory function tests are difficult to perform in Morquio syndrome patients due to their characteristic skeletal dysplasia, small body size and lack of cooperation of young patients, where in some cases, conventional spirometry for pulmonary function is too challenging. To establish feasible clinical pulmonary endpoints and determine whether age impacts lung function in Morquio patients non-invasive pulmonary tests and conventional spirometry were evaluated. The non-invasive pulmonary tests: impulse oscillometry system, pneumotachography, and respiratory inductance plethysmography in conjunction with conventional spirometry were evaluated in twenty-two Morquio patients (18 Morquio A and 4 Morquio B) (7 males), ranging from 3 to 40 years of age. Twenty-two patients were compliant with non-invasive tests (100%) with the exception of IOS (81.8%-18 patients). Seventeen patients (77.3%) were compliant with spirometry testing. All subjects had normal vital signs at rest including >95% oxygen saturation, end tidal CO2 (38-44 mmHg), and age-appropriate heart rate (mean=98.3, standard deviation=19) (two patients were deviated). All patients preserved normal values in the impulse oscillometry system, pneumotachography, and respiratory inductance plethysmography, although predicted forced expiratory total (72.8±6.9 SE%) decreased with age and was below normal; phase angle (35.5±16.5°), %rib cage (41.6±12.7%), resonant frequency, and forced expiratory volume in 1 s/forced expiratory volume total (110.0±3.2 SE%) were normal and not significantly impacted by age. The proposed non-invasive pulmonary function tests are able to cover a greater number of patients (young patients and/or wheel-chair bound), thus providing a new diagnostic approach for the assessment of lung function in Morquio syndrome which in many cases may be difficult to evaluate. Morquio patients studied herein demonstrated no clinical or functional signs of restrictive and

    Background Although there is a growing interest in developing circulating microRNA (miRNA) as noninvasive diagnostic biomarkers for the detection of high-risk colorectal adenomas and early-stage CRCs, but the comparative diagnostic significance of serum vs. exosomal miRNAs remains unexplored. Methods Based upon published literature, we performed an initial discovery step by investigating the expression of a miRNA panel in 20 normal colonic mucosa, 27 adenomas, and 19 CRC tissues. We performed subsequent validation by quantifying expression of candidate miRNAs in total serum and in exosomes from 26 adenoma patients and 47 healthy controls, and evaluated their clinical significance and potential diagnostic value in colorectal adenomas. Results We observed that the expression of four miRNAs, miR-21, miR-29a, miR-92a, and miR-135b, was significantly higher in colorectal adenomas vs. normal colonic mucosa. During validation, expression of miR-21, miR-29a and miR-92a in serum was significantly higher in adenomas vs. healthy controls, significantly correlated with adenoma size and total adenoma number within the colorectum, and significantly discriminated patients with advanced adenomas. In contrast, although exosomal miR-21 and miR-29a levels in adenoma patients were significantly higher than those of healthy volunteers, only exosomal miR-21 significantly correlated with adenoma size and total adenoma number, and could discriminate patients with high-risk adenomas. Conclusion Compared to exosomal miRNAs, serum levels of miR-21, miR-29a and miR-92a are superior diagnostic biomarkers in patients with high-risk adenomatous polyps. PMID:27760147

    Background Pulmonary Rehabilitation for moderate Chronic Obstructive Pulmonary Disease in primary care could improve patients’ quality of life. Methods This study aimed to assess the efficacy of a 3-month Pulmonary Rehabilitation (PR) program with a further 9 months of maintenance (RHBM group) compared with both PR for 3 months without further maintenance (RHB group) and usual care in improving the quality of life of patients with moderate COPD. We conducted a parallel-group, randomized clinical trial in Majorca primary health care in which 97 patients with moderate COPD were assigned to the 3 groups. Health outcomes were quality of life, exercise capacity, pulmonary function and exacerbations. Results We found statistically and clinically significant differences in the three groups at 3 months in the emotion dimension (0.53; 95%CI0.06-1.01) in the usual care group, (0.72; 95%CI0.26-1.18) the RHB group (0.87; 95%CI 0.44-1.30) and the RHBM group as well as in fatigue (0.47; 95%CI 0.17-0.78) in the RHBM group. After 1 year, these differences favored the long-term rehabilitation group in the domains of fatigue (0.56; 95%CI 0.22-0.91), mastery (0.79; 95%CI 0.03-1.55) and emotion (0.75; 95%CI 0.17-1.33). Between-group analysis only showed statistically and clinically significant differences between the RHB group and control group in the dyspnea dimension (0.79 95%CI 0.05-1.52). No differences were found for exacerbations, pulmonary function or exercise capacity. Conclusions We found that patients with moderate COPD and low level of impairment did not show meaningful changes in QoL, exercise tolerance, pulmonary function or exacerbation after a one-year, community based rehabilitation program. However, long-term improvements in the emotional, fatigue and mastery dimensions (within intervention groups) were identified. Trial registration ISRCTN94514482 PMID:23399113

She had a history of aborted cardiac arrest and syncope and had received treatment with propranolol for 15 years. However, because she developed adult-onset asthma we tried to switch propranolol, a nonselective beta-blocker, to beta-1-cardioselective agents, bisoprolol and metoprolol. These resulted in both a markedly prolonged corrected QT interval and the development of LQTS-associated arrhythmias. Eventually, propranolol was reinitiated at a higher dose with the addition of verapamil, and she has had no further cardiac or asthmatic events for 5 years.

    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 report the case of a terminally ill cancer patient with recurrent pericardial and bilateral pleural effusions who was scheduled for video-assisted thoracoscopic surgery. The operation was performed with the patient awake under epidural anaesthesia. The patient's cough reflex in response to lung manipulation was successfully minimised by the inhalation of aerosolised lidocaine. Video-assisted thoracic surgery requires the exclusion of a lung from ventilation. In order to support one-lung spontaneous ventilation in this high-risk patient, we successfully used non-invasive bilevel positive airway pressure ventilation via a facemask. Based on this preliminary experience, we think that critically ill patients scheduled for palliative surgery can be successfully managed with the combination of minimally invasive surgical techniques and neuraxial block with non-invasive lung ventilation.

    Pulmonary mucormycosis is a rare, devastating, opportunistic fungal infection, caused by the ubiquitous filamentous fungi of the Mucorales order of the class of Zygomycetes. This infection occurs principally in some particular conditions, specially in diabetic patients and immunocompromised host, and rarely in cirrhotic patients. The diagnosis of mucormycosis can only be confirmed by pathological and mycological examination of biopsy specimens. We report a case of pulmonary mucormycosis in a 68-year-old woman with underlying liver cirrhosis and diabetes mellitus. Endoscopic and radiologic findings supported the diagnosis of hydatid cyst of the lung. The patient underwent surgical resection and was started on amphotericin B, after pathological examination. Unfortunately, she succumbed to the infection within one month of surgery.

  9. Depression in patients with chronic obstructive pulmonary disease.

    2012-05-01

    Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality in adults in the United States and worldwide. Depression is a common comorbidity in this population, but often goes undiagnosed in persons with COPD. Because the presence of depression has the potential to negatively impact COPD-related outcomes, it is essential for health care practitioners involved in the care of patients with COPD to diagnose and treat COPD and the associated comorbidities, including depression. Although there is a lack of comprehensive guidelines for treating depression in those with COPD, an algorithm has been proposed to screen and manage depression in these patients. Several questionnaires are available that can be used to assess and assist in diagnosing depression in these patients. Following diagnosis, antidepressant therapy should be considered along with nonpharmacological strategies, such as pulmonary rehabilitation and cognitive behavioral therapy.

    The need to recognize and manage psychiatric co-morbidity in tuberculosis (TB) patients in primary care settings in order to improve adherence to the treatment is now well documented. Pulmonary TB patients at the District TB Control Office and TB Centre in Haripur from December 2007 to March 2008 were evalute in order to assess the frequency of anxiety and depression and continuation of treatment. Forty seven out of 65 (72%) TB patients had severe/moderate level of anxiety and depression according to Hospital Anxiety and Depression Scale (HADS). Fourteen (22%) TB patients with co-morbid anxiety and depression showed multi drug-resistance (MDR-TB).

    Objective: To assess the incidence, possible risk factors and prognosis of pulmonary arterial hypertension (PAH) in critically ill elderly patients. Methods: We selected 122 cases admitted to the ICU, ages 60–93 years old. An echocardiography examination was performed within four days after admission to the ICU. PAH is usually suspected if the patient’s pulmonary artery systolic pressure ≥ 40 mmHg. We collected echocardiography data, relevant clinical data and routine laboratory data; we then used a statistical method to analyze the risk factors for PAH in critically ill elderly patients and examined its impact on the prognosis. Results: Total 51 patients were diagnosed with PAH. The prevalence of critically ill elderly patients with PAH was 41.8%. The ANOVA analysis showed that if patients had COPD (P = 0.031) and/or respiratory failure (P = 0.021), they were more prone to PAH. An enlarged left atrium (P = 0.038) and/or right ventricle (P = 0.029), a declining left ventricle fractional shortening rate (P = 0.038), and an elevated amount of the brain natriuretic peptides (P = 0.046) were all associated with the occurrence of PAH. Multivariate regression analysis showed that the left atrial diameter (P = 0.045) was the risk factor in critically ill elderly patients with PAH. The 30-day mortality rate was 33.3% for elderly patients with PAH, which is statistically significant (P = 0.035) when compared with the mortality rate of patients with normal pulmonary artery pressure. Our multivariate regression analysis also showed that, for critically ill elderly patients admitted in the ICU, PAH (P = 0.039) is risk factor for increased mortality. Conclusions: A higher incidence of PAH occurs in critically ill elderly patients. PAH is more likely to occur in patients with an enlarged left atrium, and these problems adversely impact the prognosis. PMID:28367167

    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.

    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.

    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

    Although post-operative adjuvant chemotherapy (ACT) is only recommended for patients with stage II colon cancer who are at a high risk of recurrence, the definition of high risk remains unclear. The present study aimed to identify the risk factors for recurrence, which may also be indicators for adjuvant therapy, using a retrospective analysis of clinicopathological data obtained from stage II colon cancer patients who had undergone a curative resection. The present study also investigated the effects of ACT in patients who displayed the risk factors for recurrence. Univariate and multivariate analyses of the data collected from 377 stage II colon cancer patients, treated at Kurume University Hospital (Fukuoka, Japan) between 1982 and 2005, was conducted in order to determine and compare the risk factors for recurrence between the 163 patients who had undergone adjuvant therapy and the 214 patients who had not undergone adjuvant therapy. The risk factors for recurrence in patients who had not undergone adjuvant therapy were a serum carcinoembryonic antigen (CEA) level that was twice the cut-off value and pre-operative bowel obstruction. Adjuvant therapy provided no benefit to patients who presented with neither risk factor, but significantly decreased the recurrence rate in patients presenting with one or both risk factors. Based on these findings, serum CEA levels of twice the cut-off value and pre-operative bowel obstruction were proposed as indicators in the assessment for adjuvant chemotherapy following a curative resection for stage II colon cancer. These results warrant further clinical study of ACT in patients with one or both risk factors. PMID:24137386

    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.

    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

    STUDY OBJECTIVE: To assess the incidence of pulmonary hypertension (PH) in patients with chronic myeloproliferative disorders (CMPD). METHOD: Twenty-seven patients with a diagnosis of CMPD were included in the study. Patients were excluded if they had a secondary cause of PH. Diagnosis of PH was established if right ventricular systolic pressure (RVSP) by transthoracic echocardiography (TTE) was >35 mmHg. RESULTS: Diagnosis of PH was established in 14 out of 27 patients. Two patients were excluded from analysis because of poor ejection fraction on TTE, resulting in a final diagnosis of PH in 12 of 25 (48%) patients. Of these 25 patients, seven of nine with essential thrombocytosis (ET), five of 14 with polycythemia vera (PV), and 0 out of two with chronic myeloid leukemia (CML) had PH. All patients were asymptomatic at the time of their most recent visit. There was no relationship between PH and age at diagnosis, duration of disease, platelet count and hematocrit at diagnosis or during follow-up, both for the entire cohort or for specific diagnosis of ET or PV. CONCLUSION: Pulmonary hypertension appears to be common in patients with CMPD. Further studies are needed to evaluate the impact of treatment on PH and long-term survival in these 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.

    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.

    Patients with pulmonary regurgitation after tetralogy of Fallot repair have impaired aerobic capacity; one of the reasons is the decreasing global ventricular performance at exercise, reflected by decreasing peak oxygen pulse. The aims of our study were to evaluate the impact of pulmonary valve replacement on peak oxygen pulse in a population with pure pulmonary regurgitation and with different degrees of right ventricular dilatation and to determine the predictors of peak oxygen pulse after pulmonary valve replacement. The mean and median age at pulmonary valve replacement was 27 years. Mean pre-procedural right ventricular end-diastolic volume was 182 ml/m2. Out of 24 patients, 15 had abnormal peak oxygen pulse before pulmonary valve replacement. We did not observe a significant increase in peak oxygen pulse after pulmonary valve replacement (p=0.76). Among cardiopulmonary test/MRI/historical pre-procedural parameters, peak oxygen pulse appeared to be the best predictor of peak oxygen pulse after pulmonary valve replacement (positive and negative predictive values, respectively, 0.94 and 1). After pulmonary valve replacement, peak oxygen pulse was well correlated with left ventricular stroke and end-diastolic volumes (r=0.67 and 0.68, respectively). Our study confirms the absence of an effect of pulmonary valve replacement on peak oxygen pulse whatever the initial right ventricular volume, reflecting possible irreversible right and/or left ventricle lesions. Pre-procedural peak oxygen pulse seemed to well predict post-procedural peak oxygen pulse. These results encourage discussions on pulmonary valve replacement in patients showing any decrease in peak oxygen pulse during their follow-up.

    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.

    Blood flow in the pulmonary artery was studied by Doppler colour flow mapping and cardiac catheterisation in 19 patients with a ductus arteriosus and different pulmonary artery pressures. In the four patients with normal pulmonary artery pressures colour Doppler flow mapping showed multicoloured wide and long systolic and diastolic jets in the pulmonary artery. In the 15 patients with raised pulmonary arterial pressure the systolic jets varied from multicoloured to red and were thinner: in patients with considerably raised pulmonary arterial pressure the jets became redder during diastole. The Doppler velocity tracings showed that in patients with normal pulmonary artery pressures the mean peak systolic velocity was higher than the mean end diastolic velocity--so that in all four the ratio of peak systolic velocity to end diastolic velocity was less than 2. The mean peak systolic velocity was much higher than the mean end diastolic velocity in 13 of the 15 patients with raised pulmonary artery pressure; this meant that the ratio of peak systolic velocity to end diastolic velocity was greater than 2 in 10 of 11 patients. The end diastolic velocity was significantly lower in those patients with raised pulmonary artery pressure than in those with normal artery pressure. There was an inverse linear correlation between the mean pulmonary artery pressure and end diastolic ductal jet velocity in 17 of the 19 patients. Colour flow mapping and this quantitative Doppler technique can detect pulmonary artery hypertension in patients with a ductus arteriosus. Images PMID:2278800

    The aim of this study was to investigate the utility of pulmonary rehabilitation for improving of exercises efficiency, dyspnea, and quality of life of patients with lung cancer during chemotherapy. After the enrollment selection, the study included 20 patients with newly diagnosed advanced lung cancer and performance status 0-2. There were 12 patients randomly allocated to the pulmonary rehabilitation group and another 8 constituted the control group that did not undergo physical rehabilitation. Both groups of patients had continual cycles of chemotherapy. Data were analyzed before and after 8 weeks of physical rehabilitation, and before and after 8 weeks of observation without rehabilitation in controls. The inpatient rehabilitation program was based on exercise training with ski poles and respiratory muscle training. We found a tendency for enhanced mobility (6 Minute Walk Test: 527.3 ± 107.4 vs. 563.9 ±64.6 m; p > 0.05) and a significant increase in forced expired volume in 1 s (66.9 ± 13.2 vs. 78.4 ± 17.7 %predicted; p = 0.016), less dyspnea (p = 0.05), and a tendency for improvement in the general quality of life questionnaire after completion of pulmonary rehabilitation as compared with the control group. This report suggests that pulmonary rehabilitation in advanced lung cancer patients during chemotherapy is a beneficial intervention to reduce dyspnea and enhance the quality of life and mobility.

    This study was conducted to address possible differences in pathogenesis of chronic pulmonary thromboembolism in comparison with that in acute pulmonary embolism using In-111 labeled platelet scintigraphy. Six patients with acute pulmonary embolism and eight patients with chronic pulmonary embolism were involved in this study. Pulmonary emboli were confirmed by angiography. In each patient, autologous platelets were collected from a venous blood sample of 50 ml and labeled with 18.5 MBq of In-111 chloride using a method previously reported. Whole body and spot view images were obtained at twenty-four hours following intravenous administration of In-111 labeled platelets. Images were interpreted visually by two observers. In acute pulmonary embolism no definite abnormal accumulation was seen in the areas of pulmonary emboli, which was mostly consistent with previously published results. In chronic pulmonary embolism, three out of nine patients (33%) showed tracer accumulation corresponding to the areas of emboli in pulmonary vessels. These patients showed significantly lower arterial oxygen pressure in comparison with other patients without abnormal tracer accumulation. In addition, two of the three chronic patients with positive intrathoracic accumulation showed abnormal tracer uptake in the lower extremities. Surgical thrombectomy confirmed presence of progressive thrombi in the pulmonary arteries in scan positive patients. These results suggest possible mechanisms for thrombus formation and progression in the pulmonary vessels following initial thromboembolic events, which worsen the patient`s condition and cause a prolonged clinical course of pulmonary embolism. In-111 labeled scintigraphy can be used to depict possible thrombus formation in the pulmonary vessels in chronic pulmonary thromboembolic patients, who might require different therapeutic interventions from those for acute pulmonary embolism.

    Sorafenib is the standard systemic treatment for patients with advanced hepatocellular carcinoma (HCC); however, its therapeutic value in patients with HCC following resection remains controversial. The current retrospective study was undertaken to assess the effects of sorafenib treatment following surgical resection in patients with advanced HCC disease who were at a high risk for recurrence. Between July 2010 and July 2013, a consecutive cohort of 42 patients with advanced HCC and at a high risk of recurrence (i.e., those with portal vein tumor thrombosis, adjacent organ involvement or tumor rupture) who underwent resection were analyzed. The patients were categorized into the sorafenib group (n=14) or the best supportive care (BSC) group (n=28). Although the histological grade, Barcelona Clinic Liver Cancer Stage, tumor size, nodule number and proportion of patients with high serum α-fetoprotein levels were comparable between the sorafenib and BSC groups, those receiving sorafenib following resection had significantly longer disease-free survival (DFS) of 5.2 months [95% confidence interval (CI), 1.2–9.2 months] compared with the BSC group [1.8 months (95% CI, 0.6–3.0 months)]. No differences in overall survival were noted between the groups. Furthermore, no drug-related adverse events resulted in discontinuation of sorafenib therapy. Univariate log-rank analysis revealed that sorafenib treatment (P=0.002) and treatment prior to resection (P=0.012) were significantly associated with longer DFS; however, sorafenib therapy (P=0.027) and tumor size (P=0.028) were associated with longer DFS by multivariate analysis. Furthermore, sorafenib was well-tolerated and improved DFS in patients with advanced HCC who underwent hepatic resection. Thus, tumor resection followed by sorafenib therapy may represent an effective therapeutic strategy for patients with advanced HCC. This possibility should be confirmed in larger, multicenter studies. PMID:28356989

    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

    A 44-year-old male patient visited our hospital with a chief complaint of macroscopic hematuria. Prostate biopsies were performed due to prostate specific antigen (PSA) 11.6 ng/ml, and he was diagnosed with Gleason score 5+4 prostate cancer. Computed tomography showed a left hypoplastic kidney. T2- weighted magnetic resonance imaging showed the left ureter stump with ectopic insertion into the dilated left seminal vesicle. He was diagnosed with high-risk prostate cancer and left ectopic ureter inserting into the seminal vesicle with ipsilateral hypoplastic kidney. Laparoscopic left nephroureterectomy and open radical prostatectomy were performed.

    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

    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

    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.

    Body composition is a non-invasive method, which gives us information about the distribution of tissues in the body structure, it is also an indicator of the risk of mortality in patients with chronic obstructive pulmonary disease. The heart rate variability is a technique that gives us information of autonomic physiological condition, being recognized as an indicator which is decreased in a number of diseases. The purpose of this study was to assess body composition and heart rate variability. The methodology used is that of Debora Kerr (1988) endorsed by the International Society for advances in Cineantropometría for body composition and heart rate variability of the guidelines described by the American Heart Association (1996). Roscraff equipment, caliper Slimguide and watch Polar RS 800CX was used. , BMI 26.7 ± 3.9 kg / m²; Muscle Mass 26.1 ± 6.3 kg ; Bone Mass 1.3 kg ± 8.1 76 ± 9.9 years Age : 14 candidates for pulmonary rehabilitation patients were evaluated , Adipose mass 16.4 ± 3.6 kg ; FEV1 54 ± 14%. Increased waist circumference and waist hip ratio was associated with a lower overall heart rate variability. The bone component was positively related to the variability of heart rate and patients with higher forced expiratory volume in one second had lower high frequency component in heart rate variability. In these patients, the heart rate variability is reduced globally and is associated with cardiovascular risk parameters.

    To supplement limited relevant literature, we retrospectively compared ablation and disease outcomes in high-risk differentiated thyroid carcinoma (DTC) patients undergoing radioiodine thyroid remnant ablation aided by recombinant human thyrotropin (rhTSH) versus thyroid hormone withdrawal/withholding (THW). Our cohort was 45 consecutive antithyroglobulin antibody- (TgAb-) negative, T3-T4/N0-N1-Nx/M0 adults ablated with high activities at three referral centers. Ablation success comprised negative (<1 μg/L) stimulated serum thyroglobulin (Tg) and TgAb, with absent or <0.1% scintigraphic thyroid bed uptake. “No evidence of disease” (NED) comprised negative unstimulated/stimulated Tg and no suspicious neck ultrasonography or pathological imaging or biopsy. “Persistent disease” was failure to achieve NED, “recurrence,” loss of NED status. rhTSH patients (n = 18) were oftener ≥45 years old and higher stage (P = 0.01), but otherwise not different than THW patients (n = 27) at baseline. rhTSH patients were significantly oftener successfully ablated compared to THW patients (83% versus 67%, P < 0.02). After respective 3.3 yr and 4.5 yr mean follow-ups (P = 0.02), NED was achieved oftener (72% versus 59%) and persistent disease was less frequent in rhTSH patients (22% versus 33%) (both comparisons P = 0.03). rhTSH stimulation is associated with at least as good outcomes as is THW in ablation of high-risk DTC patients.

    Coronary perforation is a rare complication in patients undergoing percutaneous coronary angioplasty. The mortality of this complication varies depending on factors related to the patient and the procedure performed, reaching 44% in patients with Ellis type III perforation. We report the case of an 81 year old male with multiple cardiovascular risk factors, who underwent percutaneous angioplasty for unstable angina management. The patient developed grade III coronary perforation in the anterior descending artery, which was successfully managed with balloon inflation to 6 atmospheres for 10 minutes twice in the affected area, with an interval of 5 minutes between each dilatation. The patient improved and was discharged.

    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.

    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.

    The purpose of this postmarket surveillance registry was to document the efficacy of a vascular prosthesis coated with metallic silver in high-risk patients undergoing vascular reconstructions. Patency (primary endpoint) and freedom from graft infection (secondary endpoint) data were assessed at a minimum of 12 months in patients with significant co-morbidity and/or confirmed graft infections or infected native vessels. Between November 2006 and December 2009, 230 patients with high-risk factors underwent aortic,peripheral and/or extra-anatomic reconstructions with Silver Graft® (SG) in six German, one French and one Polish vascular center.All participating centers used the metallic silver-coated polyester graft (SG) in various diameters and lengths including tubular and bifurcate vascular grafts. Doppler ultrasound follow-ups to determine graft patency were planned at 12 months or done at an earlier time in case the patient became symptomatic. A total of 230 patients were studied. Ten of these 230 patients had graft infections at baseline whereas the remaining 220 subjects had significant risk factors such as coronary artery disease (62.7%, 138/220), vascular access in scar tissue (27.3%, 60/220), Fontaine III/IV (38.2%, 84/220), chronic renal insufficiency (26.8%, 59/220) and diabetes (21.0%,46/220). The long-term follow-up at 15.5 ± 8.3 months revealed a secondary patency rate of 93.2% (205/220) and an ‘all cause’ mortality rate of 18.6% (41/220). There was a freedom from de novo graft infection rate of 95.9% (211/220) in the high-risk group without graft infections at baseline. One regraft infection occurred distal of the revisional reconstruction in the 10 patients with graft infection at baseline. The presence of perigraft fluid at follow-up and Fontaine III/IV at baseline were found to be predictors for graft patency whereas perigraft fluid presence was the only predictor for de novo graft infections. This registry revealed favorable patency and

    PubMed Central

    2014-01-01

    Background Huntington’s disease (HD) is a neurodegenerative disorder characterized by progressive motor, cognitive and psychiatric disturbances. Chest muscle rigidity, respiratory muscle weakness, difficulty in clearing airway secretions and swallowing abnormalities have been described in patients with neurodegenerative disorders including HD. However limited information is available regarding respiratory function in HD patients. The purpose of this study was to investigate pulmonary function of patients with HD in comparison to healthy volunteers, and its association with motor severity. Methods Pulmonary function measures were taken from 18 (11 male, 7 female) manifest HD patients (53 ± 10 years), and 18 (10 male, 8 female) healthy volunteers (52 ± 11 years) with similar anthropometric and life-style characteristics to the recruited HD patients. Motor severity was quantified by the Unified Huntington’s Disease Rating Scale-Total Motor Score (UHDRS-TMS). Maximum respiratory pressure was measured on 3 separate days with a week interval to assess test-retest reliability. Results The test-retest reliability of maximum inspiratory and expiratory pressure measurements was acceptable for both HD patient and control groups (ICC ≥0.92), but the values over 3 days were more variable in the HD group (CV < 11.1%) than in the control group (CV < 7.6%). The HD group showed lower respiratory pressure, forced vital capacity, peak expiratory flow and maximum voluntary ventilation than the control group (p < 0.05). Forced vital capacity, maximum voluntary ventilation and maximum respiratory pressures were negatively (r = -0.57; -0.71) correlated with the UHDRS-TMS (p < 0.05). Conclusion Pulmonary function is decreased in manifest HD patients, and the magnitude of the decrease is associated with motor severity. PMID:24886346

    OBJECTIVES: This study described the characteristics of the systemic arterial supply of pulmonary sequestration (PS) in an attempt to better distinguish PS from other acquired lesions. METHODS: We identified 25 patients hospitalized at the Peking Union Medical College Hospital during January 2013 to December 2015 with the assistance of medical catalogers. Twenty-three patients with a definite diagnosis of “pulmonary sequestration” clinically or pathologically were included in the study. The medical records, imaging information, and pathological data were reviewed retrospectively. The general characteristics of the patients and the features of the anomalous arteries were summarized. RESULTS: Aberrant arterial supply of PS was found in all 23 (100%) cases. Among them, twenty patients received surgery, including 14 (70%) with aberrant arterial supply found before surgery, and the other 6 (30%) found during surgery. Nineteen (82.6%) patients had a single systematic arterial supply, with a median diameter of 8 mm. More than one arterial supplies were found in four (17.4%) cases. In 21 (91.3%) cases, the anomalous systemic artery originated from the descending thoracic aorta just adjacent to the sequestrated lung which it supplied, without the presence of accompanying bronchi. In twenty (87.0%) patients who received the surgical intervention, samples of 12 (85.7%) were proved to have elastic vessel walls, out of the 14 samples in which the anomalous systemic arteries were available for analysis. CONCLUSIONS: There are no certain pathology diagnostic criteria for the diagnosis of PS. The detecting of the aberrant systematic artery and distinguishing it from the bronchial arteries corresponded to certain lung abnormalities are the keys to the accurate diagnosis of pulmonary sequestration in adult patients. We propose that the characteristic features of the anomalous arteries include: Originating from aorta and its main branches, adjacent to the sequestrated area

    Background This study aimed to evaluate the impact of preoperative pulmonary rehabilitation in lung cancer patients undergoing pulmonary resection surgery with marginal lung function. Methods Short-term outcomes of 42 patients with forced expiratory volume in 1 s < 1.6 L who underwent lung resection between 01/2006 and 12/2010 were reviewed retrospectively. They were divided into group A (no preoperative pulmonary rehabilitation) and group B (receiving pulmonary rehabilitation). In group B, a second set of pulmonary function tests was obtained. Results There were no significant differences in terms of sex, age, race, pathologic stage, operative procedure, or smoking years. Mean forced expiratory volume in 1 s and diffusing capacity for carbon monoxide in group A was 1.40 ± 0.22 L and 10.28 ± 2.64 g∙dL(-1) vs. 1.39 ± 0.13 L and 10.75 ± 2.08 g∙dL(-1) in group B. Group B showed significant improvement in forced expiratory volume in 1 s from 1.39 ± 0.13 to 1.55 ± 0.06 L ( p = 0.02). Mean intensive care unit stay was 6 ± 5 days in group A vs. 9 ± 9 days in group B ( p = 0.22). Mean hospital stay was 10 ± 4 days in group A vs. 14 ± 9 days in group B ( p = 0.31). There was no significant difference in morbidity or mortality between groups. Conclusion Preoperative pulmonary rehabilitation can significantly improve forced expiratory volume in 1 s in some marginal patients undergoing lung cancer resection. However, it does not improve length of stay, morbidity, or mortality.

    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.

    Background To evaluate the impact of duration of Impella 2.5 support (Abiomed, Danvers, MA) on hospitalization of patients after high-risk percutaneous coronary intervention (PCI). There has been a continuous increase in prevalence of coronary artery disease with more patients needing PCI during acute myocardial infarction. Some of these patients have to undergo high-risk revascularization with circulatory support like the Impella 2.5 device. Methods This study was a single center retrospective study of patients admitted to our hospital who required Impella circulatory support during percutaneous coronary intervention. Patients’ medical records, cardiac catheterization laboratory and 2-D echocardiography reports were reviewed to ascertain left ventricular ejection fraction, duration of Impella support, Coronary Care Unit (CCU) days and the length of stay in the hospital. A P-value of ≤ 0.05 was considered statistically significant. Results Over a 15-month period, we had 25 patients with 19 males and 6 females. Mean age of the patient cohort was 68 ± 10 years. Mean LVEF of the group was 32 ± 16%. Mean length of hospital stay was 8 ± 8 days and mean CCU stay was 4 ± 4 days. The Impella was successfully inserted in all cases with a median duration of support of 70 minutes (range, 4 - 5760 minutes). Bleeding complication occurred in 8%. Spearman's rank correlation coefficient between the duration of Impella support and hospital stay was 0.49 (P = 0.023) while it was 0.71 (P = 0.001) between Impella support duration and CCU days. Conclusions Our study suggests that there is a positive correlation between the duration of Impella 2.5 circulatory support and hospital stay and/or CCU days. The correlation seems to be stronger with CCU days.

    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.

    Background Current understanding of human immunodeficiency virus (HIV)-associated pulmonary cryptococcosis (PC) is largely based on studies performed about 2 decades ago which reported that the most common findings on chest radiograph were diffuse interstitial infiltrates. Few studies are available regarding the computed tomography (CT) findings. The aim of this study was to characterize chest CT features of HIV-associated PC. Methods HIV patients with cryptococccal infection and pulmonary abnormalities on Chest CT between September 2010 and May 2016 in the Second Affiliated Hospital of the Southeast University were retrospectively analyzed. Confirmed cases of tumors, mycobacterial infections and other fungal infections were excluded from the analysis. Results 60 cases were identified. The median CD4 T-cell counts were 20 cells/μL (range, 0–205 cells/μL). Chest CT scans demonstrated nodular lesions in 93.3% of the studied patients. Those nodular lesions were usually cavitated and solitary nodule was the most common form. Pleural effusions and pneumonic infiltrates occurred in 11.6% and 31.7% of the cases respectively. Those lesions were usually had co-existing nodular lesions. Etiological analysis suggested that 76.8% of the nodular lesions could have a relationship with PC that 12.5% of the nodular lesions were “laboratory-confirmed” cases, 48.2% were “clinically confirmed” cases and 16.1% were “clinically probable” cases. 85.7% of the pleural effusions could be “clinically confirmed” cases of PC. At least, 38.5% of the diffuse pneumonic infiltrates may be clinically attributed to pneumocystis pneumonia. Conclusions This study suggested that pulmonary nodules but not diffuse pneumonia are the most common radiological characteristics of HIV-associated PC. HIV-infected patients with pulmonary nodules on Chest CT should particularly be screened for cryptococcal infection. PMID:28301552

    Purpose: The objectives of this study were to investigate the expression of survivin in tumor samples from patients with high-risk T1 bladder cancer and to correlate its expression with clinicopathologic features as well as clinical outcomes after initial transurethral resection (TURBT) followed by radiotherapy (RT) or radiochemotherapy (RCT). Methods and Materials: Survivin protein expression was evaluated by immunohistochemistry on tumor specimen (n = 48) from the initial TURBT, and was correlated with clinical and histopathologic characteristics as well as with 5-year rates of local failure, tumor progression, and death from urothelial cancer after primary bladder sparring treatment with RT/RCT. Results: Survivin was not expressed in normal bladder urothelium but was overexpressed in 67% of T1 tumors. No association between survivin expression and clinicopathologic factors (age, gender, grading, multifocality, associated carcinoma in situ) could be shown. With a median follow-up of 27 months (range, 3-140 months), elevated survivin expression was significantly associated with an increased probability of local failure after TURBT and RCT/RT (p = 0.003). There was also a clear trend toward a higher risk of tumor progression (p = 0.07) and lower disease-specific survival (p = 0.10). Conclusions: High survivin expression is a marker of tumor aggressiveness and may help to identify a subgroup of patients with T1 bladder cancer at a high risk for recurrence when treated with primary organ-sparing approaches such as TURBT and RCT.

    OBJECTIVES Although pulmonary valve-sparing repair is preferable for patients with tetralogy of Fallot, the repair of very small pulmonary valves is challenging. The present study evaluates our modification for preserving severely hypoplastic pulmonary valves in patients with tetralogy of Fallot. METHODS Sixty-eight consecutive patients who underwent complete repair of a tetralogy of Fallot between 2005 and 2011 were retrospectively reviewed. Patients with pulmonary atresia, absence of a pulmonary valve, atrioventricular septal defect and/or subarterial ventricular septal defect were excluded. There were 19 (28%) patients with a severely hypoplastic pulmonary annulus determined by preoperative echocardiography (z-score <−4). For these patients, we collected echocardiographic data and information about their postoperative course. RESULTS Valve preserving was successful in 11 of 19 (58%) of the z < −4 group, compared with 48 of 49 (98%) of the z > −4 group. In the z < −4 valve-sparing subgroup (n = 11), the preoperative pulmonary valve diameter z-score was −4.9 (range −6.3 to −4.3), and an approach involving ventriculotomy with no transannular patch was employed at a mean age of 6.9 (range 2.2–16.1) months. In this subgroup, residual right ventricular outflow tract velocity was 2.4 ± 0.6 m/s at discharge from the hospital. During a mean follow-up of 2.6 ± 2.4 years, no reintervention was necessary. Late right ventricular outflow tract velocity was 2.2 ± 0.6 m/s, and there was no severe pulmonary regurgitation. The pulmonary valve annulus grew in relation to the patient's body surface area (z = −0.51, range −4.2–0.24) without any aneurysmal changes in the right ventricular outflow tract. CONCLUSIONS Although our modification of valve-sparing repair for severely hypoplastic pulmonary valves in patients with tetralogy of Fallot could not be applied in all patients, this strategy enabled acceptable growth of the valve annulus, with only mild

    In the Greek pilot of the e-Vital project, remote telemedicine services are provided to chronic cardiac and pulmonary patients who are not confined to a hospital (i.e. receiving home/ambulatory health care) with the aim of exploring the dynamics of interactive continuous chronic patient monitoring, particularly focusing on the impact on patient's quality of life, the patient's active involvement in their own care and according impact on the overall quality of healthcare provision, as well as the benefits for healthcare providers (time management, patient management, savings, etc). The current trial in progress validates the business potential of remote monitoring services and demonstrates the technical environment that enables patient-doctor interaction regardless of location and the according communication modes and protocols. The domain for applying the envisaged service is the private healthcare sector and the users groups include individual chronic patients with cardiac and pulmonary diseases. So far, from the patient's point of view, the service mainly appeals to patients with arrhythmias due to lightweight technology and easy processes involved in the transmission of 1-lead ECG. Asthma and COPD patients are also enthusiastic, as they can receive doctor advice in real time. From the health professional's point of view the service has real added value in the fields of diagnosis, prevention, monitoring and follow up. In the case of asthma and COPD the value of the service in diagnosis is even more apparent as these patients may be asymptomatic, when they visit their doctor and have exacerbations when they are at home. e-Vital in this case ensures that the healthcare professional will acquire the complete image of the patient condition. Finally, the experiences gained so far indicate that e-Vital could be particularly efficient in isolated areas, with shortage of experienced scientific personnel.

    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.

    HR-HPV subtypes are strongly linked to etiology of many human cancers including oral cancer. The epidemiology of infection with different HPV genotypes greatly varies in different countries. The aim of this study was to identify and genotype the HR-HPV subtypes in oral tissues obtained from Sudanese patients with oral lesions. In this retrospective study 200 patients with oral lesions were screened by molecular methods (PCR) for the presence of HR-HPV subtypes. Of the 200 patients, 100/200 were patients with oral cancer (ascertained as case group) and 100/200 were patients with non-neoplastic oral lesions (ascertained as control group). Out of the 200 patients, 12/200 (6%) were found with HR-HPV infection. Of the 12 positive patients, 8/12 (66.7%) were among cases and the remaining 4/12 (33.3%) were among control group. The distribution of different genotypes was: type HPV 16 6/12 (50%), HPV18 4/12 (34%), HPV 31 1/12 (8%) and HPV 33 1/12 (8%). In view of these findings, HPV particularly subtypes 16 and 18 play a role in the etiology of oral cancer in the Sudan. PMID:23641304

    This prospective study compared diagnostic and prognostic value of conventional cytologic (CC) examination and flow cytometry (FCM) of baseline samples of cerebrospinal fluid (CSF) in 174 patients with newly diagnosed aggressive non-Hodgkin lymphoma (NHL). FCM detected a neoplastic population in the CSF of 18 of 174 patients (10%), CC only in 7 (4%; P < .001); 11 patients (14%) were discordant (FCM(+)/CC(-)). At a median follow-up of 46 months, there were 64 systemic progressions and 10 CNS relapses, including 2 patients with both systemic and CNS relapses. Two-year progression-free and overall survival were significantly higher in patients with FCM(-) CSF (62% and 72%) compared with those FCM(+) CSF (39% and 50%, respectively), with a 2-year CNS relapse cumulative incidence of 3% (95% confidence interval [CI], 0-7) versus 17% (95% CI, 0-34; P = .004), respectively. The risk of CNS progression was significantly higher in FMC(+)/CC(-) versus FCM(-)/CC(-) patients (hazard ratio = 8.16, 95% CI, 1.45-46). In conclusion, FCM positivity in the CSF of patients with high-risk NHL is associated with a significantly higher CNS relapse risk and poorer outcome. The combination of IV drugs with a higher CNS bioavailability and intrathecal chemotherapy is advisable to prevent CNS relapses in FCM(+) patients.

    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.

    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.

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

    Introduction Pulmonary rehabilitation (PR) is a multidisciplinary program of care for patients with chronic obstructive pulmonary disease (COPD) with the goal of improving the functional capacity and quality of life, as well as maintaining the clinical stability of COPD sufferers. However, not all patients are available for such a program despite discomfort with their condition. The aim of this study was to evaluate the effects of a home-based PR (HBPR) program on functional ability, quality of life, and respiratory muscle strength and endurance. Patients and methods Patients with COPD according to the Global Initiative of Chronic Obstructive Lung Disease were randomized (double-blind) into two groups. One group performed a protocol at home with aerobic and muscle strength exercises and was called the intervention group; the other group received only instructions to perform breathing and stretching exercises, characterizing it as the control group (CG). We assessed the following variables at baseline and 2 months: exercise tolerance (incremental shuttle walk test and upper limb test), respiratory muscle (strength and endurance test), and health-related quality of life (Airways Questionnaire 20). Results There were no significant changes after the intervention in either of the two groups in exercise tolerance and quality of life. However, the intervention group had improved respiratory endurance compared with the CG, while the CG presented a decrease in the load sustained by the respiratory muscles after the HBPR. Conclusion A program of HBPR with biweekly supervision (although not enough to provide significant improvements in physical capacity or quality of life) played an important role in maintaining the stability of the clinical features of patients with COPD; the patients had no worsening of symptoms during the intervention period according to the daily log.

    Objective: Pulmonary hypertension is a serious complication in patients suffering from chronic obstructive pulmonary disease (COPD). The aim of this study is to investigate the effects of atorvastatin in reducing pulmonary arterial pressure in COPD patients. Methods: This double-blind, randomized trial was conducted on 42 known cases of COPD with systolic pulmonary arterial pressure of more than 25 mmHg. The patients were randomly assigned into two groups, 21 patients with atorvastatin treatment (40 mg/daily for 6 months) and 21 patients without receiving atorvastatin. All the patients participated voluntarily and provided written informed consent. The trial was registered in the Iranian Registry of Clinical Trials. Pulmonary pressure was also anticipated by Doppler echocardiography with peak pressure gradient of tricuspid regurgitation. Both groups were tested with echocardiography to measure systolic pulmonary pressure at baseline and posttreatment. Statistical analysis includes Chi-square, Student's t-test, and Wilcoxon test. P < 0.05 was considered statistically significant. Findings: The mean age was 65.8 ± 11.5 years for atorvastatin group and 63.7 ± 7.6 years for control group (P = 0.45). Baseline and posttreatment mean systolic pulmonary artery pressure (PAP) levels in the atorvastatin group were 48.9 ± 3.3 and 38.4 ± 1.9 mmHg, respectively (P = 0.007). In the control group, mean systolic PAP levels at baseline and 6 months later were 45.6 ± 3.1 and 38.9 ± 2.4 mmHg, respectively (P = 0.073). The patients treated with atorvastatin showed significant decrease in total cholesterol (P = 0.001) and low-density lipoprotein cholesterol (P = 0.008). Conclusion: A 40 mg dose of atorvastatin daily for 6 months may have beneficial effects in reducing PAP in patients with COPD. Further studies are necessary to find long-term effects of statins in COPD patients.

    Strategies to identify tumors at highest risk for treatment failure are currently under investigation for patients with bladder cancer. We demonstrate that flow cytometric detection of poorly differentiated basal tumor cells (BTCs), as defined by the co-expression of CD90, CD44 and CD49f, directly from patients with early stage tumors (T1-T2 and N0) and patient-derived xenograft (PDX) engraftment in locally advanced tumors (T3-T4 or N+) predict poor prognosis in patients with bladder cancer. Comparative transcriptomic analysis of bladder tumor cells isolated from PDXs indicates unique patterns of gene expression during bladder tumor cell differentiation. We found cell division cycle 25C (CDC25C) overexpression in poorly differentiated BTCs and determined that CDC25C expression predicts adverse survival independent of standard clinical and pathologic features in bladder cancer patients. Taken together, our findings support the utility of BTCs and bladder cancer PDX models in the discovery of novel molecular targets and predictive biomarkers for personalizing oncology care for patients.

    Treatment success in patients with acute myeloid leukaemia (AML) is heterogeneous. Cytogenetic and molecular alterations are strong prognostic factors, which have been used to individualize treatment. Here, we studied the impact of TP53 mutations on the outcome of AML patients with adverse cytogenetic risk treated with allogeneic haematopoietic stem cell transplantation (HSCT). Samples of 97 patients with AML and adverse-risk cytogenetics who had received a HSCT within three randomized trials were analysed. Complete sequencing of the TP53 coding region was performed using next generation sequencing. The median age was 51 years. Overall, TP53 mutations were found in 40 patients (41%). With a median follow up of 67 months, the three-year probabilities of overall survival (OS) and event-free survival for patients with TP53 wild type were 33% [95% confidence interval (CI), 21% to 45%] and 24% (95% CI, 13% to 35%) compared to 10% (95% CI, 0% to 19%) and 8% (95% CI, 0% to 16%) (P = 0·002 and P = 0·007) for those with mutated TP53, respectively. In multivariate analysis, the TP53-mutation status had a negative impact on OS (Hazard Ratio = 1·7; P = 0·066). Mutational analysis of TP53 might be an important additional tool to predict outcome after HSCT in patients with adverse karyotype AML.

    Prevalence and phenotype of BRCA mutation can vary by race. The purpose of this study is to evaluate the prevalence of BRCA1/2 mutations in non-familial breast cancer patients with high risks in Korea. A subset of 758 patients was selected for this study from the KOHBRA nationwide multicenter prospective cohort study. Mutations in BRCA1/2 genes were tested using fluorescent-conformation sensitive gel electrophoresis, denaturing high performance liquid chromatography or direct sequencing. Mutation of BRCA1/2 genes were identified in 65 (8.6%) patients among total 758 patients [BRCA1 mutation: 25 (3.3%), BRCA2 mutation: 40 (5.3%)]. According to risk groups, mutation of BRCA1/2 genes were identified in 53 (8.5%) of 625 early onset patients (age ≤ 40), in 22 (17.7%) of 124 bilateral breast cancer patients, in 3 (50.0%) of 6 breast and ovarian cancer patients, in one (5.9%) of 17 male breast cancer patients, in 5 cases (7.6%) of 66 multiple organ cancer patients. The most common mutation was 509C>A for BRCA1 and 7708C>T for BRCA2. The prevalence of BRCA1/2 mutations by age in early onset patients was significantly different (age <35 vs age ≥35; 10.0 vs 2.9%, p = 0.0007). BRCA1/2 mutations for non-familial Korean breast cancer patients were detected at a high rate, particularly, in patients with early onset of less than 35 years of age, bilateral breast cancer, and breast and ovarian cancer. Individualized genetic counseling should be offered for non-familial breast cancer patients with these risk factors.

    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.

    Background Sparse data are available on the prevalence of right ventricular dysfunction and/or pulmonary arterial hypertension in patients scheduled for cardiac surgery in Germany as well as on the intensity and modalities used for diagnosis, perioperative monitoring, and treatment of these comorbidities. Methods A postal survey including questions on the prevalence of preoperative right ventricular dysfunction and/or pulmonary arterial hypertension in patients undergoing cardiac surgery in 2009 was sent to 81 German heart centers. Total 47 of 81 (58%) heart centers returned the questionnaires. The centers reported data on 51,095 patients, and 49.8% of the procedures were isolated coronary artery bypass grafting. Results Data on the prevalence of preoperative pulmonary hypertension and/or right ventricular dysfunction were not available in 54% and 64.6% of centers. In the remaining hospitals, 19.5% of patients presented right heart dysfunction and 10% pulmonary arterial hypertension. Preoperative echocardiography was performed in only 45.3% of the coronary artery bypass grafting cases. Preoperative pharmacologic treatment of pulmonary hypertension or right ventricular dysfunction with oral sildenafil, inhaled prostanoids, or nitric oxide was initiated in 71% and 95.7% of the centers, respectively. Intra- and postoperative treatment was most frequently accomplished with phosphodiesterase-III inhibitors. Conclusion The prevalence of preoperative right heart dysfunction and pulmonary arterial hypertension in cardiac surgical patients in Germany seems to be substantial. However, in more than 50% of the patients, no preoperative data on right ventricular function and pulmonary arterial pressure are available. This may lead to underestimation of perioperative risk and inappropriate management of this high-risk population.

  8. Skeletal muscle dysfunction in patients with chronic obstructive pulmonary disease

    Chronic obstructive pulmonary disease (COPD) is a debilitating disease characterized by inflammation-induced airflow limitation and parenchymal destruction. In addition to pulmonary manifestations, patients with COPD develop systemic problems, including skeletal muscle and other organ-specific dysfunctions, nutritional abnormalities, weight loss, and adverse psychological responses. Patients with COPD often complain of dyspnea on exertion, reduced exercise capacity, and develop a progressive decline in lung function with increasing age. These symptoms have been attributed to increases in the work of breathing and in impairments in gas exchange that result from airflow limitation and dynamic hyperinflation. However, there is mounting evidence to suggest that skeletal muscle dysfunction, independent of lung function, contributes significantly to reduced exercise capacity and poor quality of life in these patients. Limb and ventilatory skeletal muscle dysfunction in COPD patients has been attributed to a myriad of factors, including the presence of low grade systemic inflammatory processes, nutritional depletion, corticosteroid medications, chronic inactivity, age, hypoxemia, smoking, oxidative and nitrosative stresses, protein degradation and changes in vascular density. This review briefly summarizes the contribution of these factors to overall skeletal muscle dysfunction in patients with COPD, with particular attention paid to the latest advances in the field.

    Chronic obstructive pulmonary disease (COPD) appears to be associated with osteoporosis. The aim of the study was to evaluate the prevalence of osteoporosis risk (OP risk) in a sample of patients with COPD. In 3030 patients (1768 men and 1262 women) aged >50 yr, we evaluated COPD severity with spirometry and OP risk by using a quantitative ultrasound device. We analyzed several risk factors for osteoporosis, such as age, gender, body mass index (BMI), fracture history, smoking status, glucocorticoid (GC) treatment in univariate and in multinomial logistic regressions. The risk of osteoporosis was higher in women and in older participants, among those with more severe COPD, treated with GC. In multivariate analysis, we found interactions between fracture history and smoking and between age and gender. Significant associations were found with BMI and GC treatment, whereas only a tendency, not statistically significant, was found for very severe COPD being associated to high risk of osteoporosis. In COPD patients the risk of osteoporosis is high, in particular at severe stages of the disease, but seems to be due to traditional risk factors, such as older age, female gender, low BMI, history of smoking and fractures, GC treatment.

    Sleep is highly altered during affective episodes in patients with bipolar disorder. There is accumulating evidence that sleep is also altered in euthymic states. A deficit in sleep regulation may be a vulnerability factor with aetiological relevance in the development of the disease. This study aims to explore the objective, subjective and lifetime sleep characteristics of patients with manifest bipolar disorder and persons with an elevated risk of developing the disease. Twenty-two patients with bipolar I and II disorder, nine persons with an elevated risk of developing the disorder and 28 healthy controls were evaluated with a structured interview to characterize subjective and lifetime sleeping habits. In addition, participants wore an actimeter for six nights. Patients with bipolar disorder had longer sleep latency and duration compared with healthy controls as determined by actigraphy. The subjective and lifetime sleep characteristics of bipolar patients differed significantly from healthy controls. The results of participants with an elevated risk of developing the disorder had subjective and lifetime characteristics that were largely analogous to those of patients with manifest bipolar disorder. In particular, both groups described recurring insomnia and hypersomnia, sensitivity to shifts in circadian rhythm, difficulties awakening and prolonged sleep latency. This study provides further evidence that sleep and circadian timing are profoundly altered in patients with bipolar disorder. It may also tentatively suggest that sleep may be altered prior to the first manic episode in subjects at high risk.

    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

    This prospective Phase II study is the first to assess the feasibility and efficacy of maintenance 5-azacytidine for older patients with high-risk myelodysplastic syndrome (MDS), chronic myelomonocytic leukaemia and MDS-acute myeloid leukaemia syndromes in complete remission (CR) after induction chemotherapy. Sixty patients were enrolled and treated by standard induction chemotherapy. Patients that reached CR started maintenance therapy with subcutaneous azacytidine, 5/28 d until relapse. Promoter-methylation status of CDKN2B (P15 ink4b), CDH1 and HIC1 was examined pre-induction, in CR and 6, 12 and 24 months post CR. Twenty-four (40%) patients achieved CR after induction chemotherapy and 23 started maintenance treatment with azacytidine. Median CR duration was 13.5 months, >24 months in 17% of the patients, and 18-30.5 months in the four patients with trisomy 8. CR duration was not associated with CDKN2B methylation status or karyotype. Median overall survival was 20 months. Hypermethylation of CDH1 was significantly associated with low CR rate, early relapse, and short overall survival (P = 0.003). 5-azacytidine treatment, at a dose of 60 mg/m(2) was well tolerated. Grade III-IV thrombocytopenia and neutropenia occurred after 9.5 and 30% of the cycles, respectively, while haemoglobin levels increased during treatment. 5-azacytidine treatment is safe, feasible and may be of benefit in a subset of patients.

    No indices are currently available to facilitate clinicians to identify patients who need either statin monotherapy or statin-ezetimibe combined treatment. We aimed to investigate whether cholesterol synthesis and absorption markers can predict the cholesterol-lowering response to statin. Total 306 statin-naïve patients with high risk of coronary heart disease (CHD) were treated with atorvastatin 20 mg/day for 1 month. Cholesterol synthesis and absorption markers and LDL cholesterol (LDL-C) levels were measured before and after treatment. Atorvastatin decreased LDL-C by 36.8% (range: decrease of 74.5% to increase of 31.9%). Baseline cholesterol synthesis marker lathosterol and cholesterol absorption marker campesterol codetermined the effect of atorvastatin treatment. The effect of cholesterol lowering by atorvastatin was significantly associated with baseline lathosterol levels but modified bidirectionally by baseline campesterol levels. In patients with the highest baseline campesterol levels, atorvastatin treatment decreased cholesterol absorption by 46.1%, which enhanced the effect of LDL-C lowering. Atorvastatin treatment increased cholesterol absorption by 52.3% in those with the lowest baseline campesterol levels, which attenuated the effect of LDL-C reduction. Especially those with the highest lathosterol but the lowest campesterol levels at baseline had significantly less LDL-C reduction than those with the same baseline lathosterol levels but the highest campesterol levels (27.3% versus 42.4%, P = 0.002). These results suggest that combined patterns of cholesterol synthesis/absorption markers, rather than each single marker, are potential predictors of the LDL-C-lowering effects of atorvastatin in high-risk CHD patients.

    Purpose The benefit of high-dose chemotherapy with autologous stem-cell transplantation (ASCT) as first-line treatment in patients with diffuse large B-cell lymphomas is still a matter of debate. To address this point, we designed a randomized phase III trial to compare rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP)-14 (eight cycles) with rituximab plus high-dose sequential chemotherapy (R-HDS) with ASCT. Patients and Methods From June 2005 to June 2011, 246 high-risk patients with a high-intermediate (56%) or high (44%) International Prognostic Index score were randomly assigned to the R-CHOP or R-HDS arm, and 235 were analyzed by intent to treat. The primary efficacy end point of the study was 3-year event-free survival, and results were analyzed on an intent-to-treat basis. Results Clinical response (complete response, 78% v 76%; partial response, 5% v 9%) and failures (no response, 15% v 11%; and early treatment-related mortality, 2% v 3%) were similar after R-CHOP versus R-HDS, respectively. After a median follow-up of 5 years, the 3-year event-free survival was 62% versus 65% ( P = .83). At 3 years, compared with the R-CHOP arm, the R-HDS arm had better disease-free survival (79% v 91%, respectively; P = .034), but this subsequently vanished because of late-occurring treatment-related deaths. No difference was detected in terms of progression-free survival (65% v 75%, respectively; P = .12), or overall survival (74% v 77%, respectively; P = .64). Significantly higher hematologic toxicity ( P < .001) and more infectious complications ( P < .001) were observed in the R-HDS arm. Conclusion In this study, front-line intensive R-HDS chemotherapy with ASCT did not improve the outcome of high-risk patients with diffuse large B-cell lymphomas.

    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

    We report the case of a patient with a cerebral aneurysm, located in the left middle cerebral artery. During the clipping of this aneurysm, the bispectral index (BIS) increased for no apparent reason. This was then interpreted as intraoperative non-convulsive status epilepticus. This clinical condition may have negative impact in the prognosis of the patient, so it is very important to be able to detect this conditions as early as possible. Measuring the BIS while the patient is anaesthetised could be useful in this situation, considering that an increase in values greater than 60, associated with acidosis and without any other peri-anaesthetic explanation, may provide evidence of a convulsive equivalent state, allowing appropriate action to be taken.

    The early development of lens opacities and lens subluxation are the most common causes of vision loss in patients with anterior megalophthalmos (AM). Cataract surgery in such patients is challenging, however, because of anatomical abnormalities. Intraocular lens dislocation is the most common postoperative complication. Patients with AM also seem to be affected by a type of vitreoretinopathy that predisposes them to retinal detachment. We here present the case of a 36-year-old man with bilateral AM misdiagnosed as simple megalocornea. He had a history of amaurosis in the right eye due to retinal detachment. He presented with vision loss in the left eye due to lens subluxation. Following the removal of the subluxated lens, it was deemed necessary to perform a vitrectomy in order to prevent retinal detachment. Seven months after surgery, an Artisan® Aphakia iris-claw lens was implanted in the anterior chamber. Fifteen months of follow-up data are provided. PMID:28203198

    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.

    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

    High cancerous inhibitor of PP2A (CIP2A) protein levels at diagnosis of chronic myeloid leukaemia (CML) are predictive of disease progression in imatinib-treated patients. It is not known whether this is true in patients treated with second generation tyrosine kinase inhibitors (2G TKI) from diagnosis, and whether 2G TKIs modulate the CIP2A pathway. Here, we show that patients with high diagnostic CIP2A levels who receive a 2G TKI do not progress, unlike those treated with imatinib (P=<0.0001). 2G TKIs induce more potent suppression of CIP2A and c-Myc than imatinib. The transcription factor E2F1 is elevated in high CIP2A patients and following 1 month of in vivo treatment 2G TKIs suppress E2F1 and reduce CIP2A; these effects are not seen with imatinib. Silencing of CIP2A, c-Myc or E2F1 in K562 cells or CML CD34+ cells reactivates PP2A leading to BCR-ABL suppression. CIP2A increases proliferation and this is only reduced by 2G TKIs. Patients with high CIP2A levels should be offered 2G TKI treatment in preference to imatinib. 2G TKIs disrupt the CIP2A/c-Myc/E2F1 positive feedback loop, leading to lower disease progression risk. The data supports the view that CIP2A inhibits PP2Ac, stabilising E2F1, creating a CIP2A/c-Myc/E2F1 positive feedback loop, which imatinib cannot overcome.

    Contrast-induced nephropathy (CIN) develops after the injection of iodinated contrast media. This is a post hoc analysis of the data obtained from the TRUST study, which was a prospective, multicentre, observational study conducted to evaluate the safety and tolerability of the contrast medium iopromide in patients undergoing cardiac catheterization from August 2010 to September 2011 in China, conducted to explore the current status, trends and risk predictors of hydration treatment. The status of hydration to prevent CIN in each patient was recorded. Of the total 17,139 patients from the TRUST study (mean age, 60.33 ± 10.38 years), the overall hydration usage was 46.1% in patients undergoing percutaneous coronary intervention (PCI) and 77.4%, 51.7%, and 48.5% in patients with pre-existing renal disease, diabetes mellitus, and hypertension, respectively. The proportion of hydration use increased from 36.5% to 55.5% from August 2010 to September 2011, which was independently associated with risk predictors like older age, pre-existing renal disease, hypertension, diabetes mellitus, prior myocardial infarction, ST segment elevation MI, high contrast dose, multi-vessel disease and reduced LVEF (<45%). Overall, the usage of intravenous hydration treatment for patients with a high risk of CIN following PCI was high in China. PMID:28337989

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

    A diagnostic protocol was started to study the etiology of pulmonary infiltrates in immunosuppressed patients. The diagnostic yields of the different techniques were analyzed, with special emphasis on the importance of the sample quality and the role of rapid techniques in the diagnostic strategy. In total, 241 patients with newly developed pulmonary infiltrates within a period of 19 months were included. Noninvasive or invasive evaluation was performed according to the characteristics of the infiltrates. Diagnosis was achieved in 202 patients (84%); 173 patients (72%) had pneumonia, and specific etiologic agents were found in 114 (66%). Bronchoaspirate and bronchoalveolar lavage showed the highest yields, either on global analysis (23 of 35 specimens [66%] and 70 of 134 specimens [52%], respectively) or on analysis of each type of pneumonia. A tendency toward better results with optimal-quality samples was observed, and a statistically significant difference was found in sputum bacterial culture. Rapid diagnostic tests yielded results in 71 of 114 (62.2%) diagnoses of etiological pneumonia. PMID:12037077

    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.

    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.

    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.

    BACKGROUND: To improve median survival of patients with prostate cancer that has metastasized to bone, we need to better understand the early events of the metastatic process in skeleton and develop molecular tools capable of detecting the early tumor cell dissemination into bones (micrometastasis stage). However, the initial phase of tumor cell dissemination into the bone marrow is promptly followed by the migration of tumor cells into bone matrix, which is a crucial step that signals the transformation of micrometastasis to macrometastasis stage and clinically evident metastasis. The migration of cancer cells into bone matrix requires the activation of local bone resorption. Such an event contributes to tumor cell hiding/ escaping from high immunologic surveillance of bone marrow cells. Within bone matrix, tumor cells are establishing plethoric cell-cell interactions with bone marrow-residing cells, ensuring their survival and growth. Recently, RT-PCR detections of tumor marker transcripts, such as PSA and PSMA mRNA performed in RNA extracts of peripheral blood nucleated cells and bone marrow biopsy, have enabled the stratification of patients with clinically localized prostate cancer being of high risk for extraprostatic disease and bone involvement. Therefore, it is conceivable that bisphosphonate blockade of bone resorption can inhibit the migration of tumor cells into bone matrix during the early phase of disease dissemination into bone marrow (micrometastasis stage). Consequently, assessment of the efficacy and efficiency of bisphosphonates to arrest the evolution of bone lesions in this particular clinical setting of patients with clinically localized prostate cancer and positive molecular staging status (high risk for bone involvement) is warranted.

    The risk for herpes zoster (HZ) in acute kidney injury (AKI) survivors was never explored. We identified 2,387 adults in the Taiwan National Health Insurance Research Database who recovered from dialysis-requiring AKI and matched them with non-recovery and non-AKI patients by propensity score. During a mean follow-up of 2.7 years, the incidences of HZ were 6.9, 8.2 and 4.8 episodes per 1,000 person-years in AKI-non-recovery, AKI-recovery and non-AKI group, respectively. The recovery group was more likely to develop herpes zoster than those without acute kidney injury [incidence-rate ratios 1.71, 95% confidence interval 1.16-2.52; p = 0.007]. Patients without acute kidney injury were less likely to develop herpes zoster than those AKI, recovered from dialysis or not (hazard ratio HR 0.66, 95% CI 0.46-0.95). Dialysis-requiring acute kidney injury poses a long-term risk of herpes zoster after hospital discharge. Even patients who have recovered from dialysis still carry a significantly higher risk of developing herpes zoster.

    Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are critical events associated with an accelerated loss of lung function, increased morbidity, and excess mortality. AECOPD are heterogeneous in nature and this may directly impact clinical decision making, specifically in patients with frequent exacerbations. A 'frequent exacerbator' is a sub-phenotype of chronic obstructive pulmonary disease (COPD) and is defined as an individual who experiences two or more moderate-to-severe exacerbations per year. This distinct subgroup has higher mortality and accounts for more than half of COPD-related hospitalizations annually. Thus, it is imperative to identify individuals at risk for frequent exacerbations and choose optimal strategies to minimize risk for these events. New paradigms for using combination inhalers and the introduction of novel oral compounds provide expanded treatment options to reduce the risk and frequency of exacerbations. The goals of managing frequent exacerbators or patients at risk for AECOPD are: (1) maximizing bronchodilation; (2) reducing inflammation; and (3) targeting specific molecular pathways implicated in COPD and AECOPD pathogenesis. Novel inhaler therapies including combination long-acting muscarinic agents plus long-acting beta agonists show promising results compared with monotherapy or a long-acting beta agonist inhaled corticosteroid combination in reducing exacerbation risk among individuals at risk for exacerbations and among frequent exacerbators. Likewise, oral medications including macrolides and phosphodiesterase-4 inhibitors reduce the risk for AECOPD in select groups of individuals at high risk for exacerbation. Future direction in COPD management is based on the identification of various subtypes or 'endotypes' and targeting therapies based on their pathophysiology. This review describes the impact of AECOPD and the challenges posed by frequent exacerbators, and explores the rationale for different

    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

    The purpose of this study is to evaluate the safety and efficacy of 120-W potassium titanyl phosphate (KTP) laser vaporization in patients with benign prostatic hyperplasia (BPH) who also had cardiopulmonary diseases who were taking long-term anticoagulants and were at high risk of bleeding complications. The prospective study included 188 patients with severe lower urinary tract symptoms who underwent 120-W KTP laser vaporization of the prostate. All patients were at high cardiopulmonary risk, having presented with an American Society of Anesthesiology score of 3 or greater. Of those, 45 patients were taking oral anticoagulants, and 1 had a severe bleeding disorder. BPH was successfully treated with 120-W KTP laser vaporization in all patients. Mean preoperative prostate volume ± SD was 66 ± 23.1 ml, and mean operative time was 50.8 ± 15.5 min. There were no major complications intraoperatively or postoperatively, and no blood transfusions were required. Postoperatively, only 14 patients (7.4 %) required bladder irrigation. Average catheterization time was 1.9 ± 1.5 days (range, 1-5 days). Three patients required reoperation due to enlarged prostates from residual adenoma. At 3-, 6,- 12-, and 24-month follow-ups, mean urinary peak flow increased from 8.0 ± 3.6 ml/s to 19.1 ± 5.6, 19.2 ± 4.7, 19.1 ± 4.65, and 19.2 ± 4.34 ml/s, respectively. Mean International Prostate Symptom Scores decreased over time, from 25.6 ± 5.1 (3 months) to 9.4 ± 2.8, 7.05 ± 1.46, 6.24 ± 1.36, and 6.20 ± 1.32 (24 months), respectively. 120-W HPS KTP laser vaporization is a safe and effective treatment option in BPH patients at high risk and those on anticoagulation therapy who have severe LUTS secondary to BPH.

    Two-micrometer laser resection of prostate-tangerine technique dissects whole prostatic lobes off the surgical capsular, similar to peeling a tangerine. The present study aimed to evaluate the safety and efficacy of 2-μm continuous laser vaporization in the treatment of high-risk patients with benign prostatic hyperplasia (BPH) during the 24-month follow-up. The study included 248 patients with moderate to severe lower urinary tract symptoms who underwent 2-μm continuous laser vaporization of the prostate. All patients were accompanied with different degree comorbidities and 94 patients were taking oral anticoagulants. BPH was successfully treated with 2-μm continuous laser vaporization in all patients. Mean pre-operative prostate volume was 76 ± 25.3 ml and mean operative time was 49.8 ± 16.5 min. There were no major complications intra-operatively or postoperatively, and no blood transfusions were needed. About 20 patients (8.1%) needed bladder irrigation postoperatively. Average catheterization time was 2.0 ± 1.8 days (range 1-5 days). Four patients required reoperation due to enlarged prostates from residual adenoma. At 3-, 6-, 12-, and 24-month follow-ups, maximum urinary flow rates (Qmax) increased from 6.9 ± 1.7 to 19.1 ± 4.2, 19.5 ± 4.6, 19.4 ± 4.6, and 19.5 ± 4.1 ml/s, respectively. Mean International Prostate Symptom Scores (IPSS) decreased from 27.6 ± 5.1 (pre-operation) to 9.2 ± 2.6, 7.12 ± 1.42, 6.18 ± 1.32, and 6.25 ± 1.30 at 3-, 6-, 12-, and 24-month post-operation, respectively. Two-micrometer continuous laser vaporization is a safe and effective surgical endoscopic technique associated with low complication rate in BPH patients at high risk and those on anticoagulation therapy who have severe LUTS caused by BPH.

    OBJECTIVE Barrett’s esophagus develops in 5–20% of patients with gastroesophageal reflux disease and predisposes to esophageal adenocarcinoma. The value of endoscopic biopsy surveillance is questioned because most patients do not develop cancer. Furthermore, observer variation in histological diagnosis makes validation of surveillance guidelines difficult because varying histological interpretations may lead to different estimated rates of progression. Thus, objective biomarkers need to be validated for use with histology to stratify patients according to their risk for progression to cancer. METHODS We prospectively evaluated patients using a systematic endoscopic biopsy protocol with baseline histological and flow cytometric abnormalities as predictors and cancer as the outcome. RESULTS Among patients with negative, indefinite, or low-grade dysplasia, those with neither aneuploidy nor increased 4N fractions had a 0% 5-yr cumulative cancer incidence compared with 28% for those with either aneuploidy or increased 4N. Patients with baseline increased 4N, aneuploidy, and high-grade dysplasia had 5-yr cancer incidences of 56%, 43%, and 59%, respectively. Aneuploidy, increased 4N, or HGD were detected at baseline in all 35 patients who developed cancer within 5 yr. CONCLUSIONS A systematic baseline endoscopic biopsy protocol using histology and flow cytometry identifies subsets of patients with Barrett’s esophagus at low and high risk for progression to cancer. Patients whose baseline biopsies are negative, indefinite, or low-grade displasia without increased 4N or aneuploidy may have surveillance deferred for up to 5 yr. Patients with cytometric abnormalities merit more frequent surveillance, and management of high-grade displasia can be individualized. PMID:10925966

    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).

    Twenty one DNA repair genes were analyzed in a group of 95 BC patients, who displayed clinical features of hereditary disease predisposition but turned out to be negative for mutations in BRCA1 and BRCA2 entire coding region as well as for founder disease-predisposing alleles in CHEK2, NBN/NBS1 and ATM genes. Full-length sequencing of CHEK2 and NBN/NBS1 failed to identify non-founder mutations. The analysis of TP53 revealed a woman carrying the R282W allele; further testing of additional 108 BC patients characterized by a very young age at onset (35 years or earlier) detected one more carrier of the TP53 germ-line defect. In addition, this study confirmed non-random occurrence of PALB2 truncating mutations in Russian hereditary BC patients. None of the studied cases carried germ-line defects in recently discovered hereditary BC genes, BRIP1, FANCC, MRE11A and RAD51C. The analysis of genes with yet unproven BC-predisposing significance (BARD1, BRD7, CHEK1, DDB2, ERCC1, EXO1, FANCG, PARP1, PARP2, RAD51, RNF8, WRN) identified single women carrying a protein-truncating allele, WRN R1406X. DNA sequencing of another set of 95 hereditary BC cases failed to reveal additional WRN heterozygous genotypes. Since WRN is functionally similar to the known BC-predisposing gene, BLM, it deserves to be analyzed in future hereditary BC studies. Furthermore, this investigation revealed a number of rare missense germ-line variants, which are classified as probably protein-damaging by online in silico tools and therefore may require further consideration.

    Background Positive psychological constructs have been associated with reduced suicidal ideation, and interventions to cultivate positive feelings have the potential to reduce suicide risk. This study compares the efficacy of a 6-week, telephone-based positive psychology (PP) intervention against a cognition-focused (CF) control intervention among patients recently hospitalized for depression and suicidal ideation or behavior. Method A total of 65 adults with a current major depressive episode reporting suicidal ideation or a recent suicide attempt were enrolled from participating in-patient psychiatric units. Prior to discharge, participants were randomized to the PP (n = 32) or CF (n = 33) intervention. In both interventions, participants received a treatment manual, performed weekly PP (e.g. gratitude letter) or CF (e.g. recalling daily events) exercises, and completed weekly one-on-one telephone sessions over 6 weeks. Between-group differences in hopelessness (primary outcome), depression, suicidality and positive psychological constructs at 6 and 12 weeks were tested using mixed-effects models accounting for intensity of post-hospitalization psychiatric treatment. Results Compared with PP, the CF intervention was associated with significantly greater improvements in hopelessness at 6 weeks (β = −3.15, 95% confidence interval −6.18 to −0.12, effect size = −0.84, p = 0.04), but not 12 weeks. Similarly, the CF intervention led to greater improvements in depression, suicidal ideation, optimism and gratitude at 6 and 12 weeks. Conclusions Contrary to our hypothesis, the CF intervention was superior to PP in improving hopelessness, other suicide risk factors and positive psychological constructs during a key post-discharge period among suicidal patients with depression. Further study of this CF intervention is warranted in populations at high suicide risk. PMID:27876105

    In the present study efforts are made to obtain a correlation between the trace element (TE) levels in patients and the presence of digestive cancer. The aim of the study is to detect selenium (Se), zinc (Zn) and other TE concentrations in different segments of colonic mucosa and to find out if there is any difference between the normal and pathological colonic mucosa. The concentration data (averages, standard deviations and ranges) obtained by neutron activation analysis and proton induced X-ray emission are presented and the data distribution is analyzed.

    Abstract Patients with chronic obstructive pulmonary disease (COPD) have a high risk of osteoporosis and fractures. The incidence rate of hip fracture has steadily increased over time and is a major common event in patients with osteoporosis and COPD. Total hip replacement (THR) is commonly performed in patients with hip fracture. Our aim was to compare the complications of THR between patients with and without COPD. Longitudinally linked data from the National Health Insurance Research Database, which consists of registration, claims, and reimbursement records, for a cohort of 1,000,000 randomly selected enrollees traced retrospectively from 1996 to 2000 in Taiwan. Patients who had undergone THR surgery between January 1, 2004, and December 31, 2008, were identified and divided into COPD and non-COPD cohorts. Outcomes and complications, including 90-day mortality, 1-year mortality, 1-year wound infection, 30-day readmission for hospitalization, 30-day pneumonia, 30-day acute respirat
