    Invasive fungal infection (IFI) caused by filamentous fungi remains a very severe infectious complication in patients with onco-haematological diseases. Last advances in the diagnostic and therapeutic fields, today we know that their contributions are limited. Something similar can be said of clinical trials especially in relation to some changes in the characteristics of the host. The development of promising diagnostic techniques and the relative expansion in the number of antifungal agents has been associated with diversification of therapeutic strategies (prophylaxis with extended-spectrum azoles and preemptive antifungal treatment). However, the low sensitivity of AGA testing in some circumstances, and the potential delay in starting treatment due to logistic reasons, has been reflected by a greater mortality in certain type of patients and a significant increase in the days of treatment. All these circumstances has once again focus attention to the empirical approach as a central strategy in high-risk patients. The objective of this article is to review the clinical experience in the treatment of IFI in onco-haematological patients according to data published in the literature in the last decade and to present a set of recommendations.

    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

    Full Text Available Zygomycoses are rare emerging diseases with a high fatality rate.  The most important risk factors include neutropenia or functional neutropenia, diabetic ketoacidosis, iron overload, major trauma, prolonged use of corticosteroids, illicit intravenous drug use, neonatal prematurity, malnourishment, and pre-exposure to antifungal agents with no activity against zygomycetes, such as voriconazole and caspofungin. A high index of suspicion is crucial for the diagnosis, as prompt and appropriate management can considerably reduce morbidity and mortality. Suspicion index can be increased through recognition of the differential patterns of clinical presentation. In the non- haematological immunocompromised patients, zygomycosis can manifest in various clinical forms, depending on the underlying condition: mostly as rhino-orbital or rhino-cerebral in diabetes patients, pulmonary infection in patients with malignancy or solid organ transplantation, disseminated infection in iron overloaded or deferoxamine treated patients, cerebral - with no sinus involvement - in ID users, gastrointestinal in premature infants or malnourishment, and cutaneous after direct inoculation in immunocompetent individuals with trauma or burns. Treating a patient’s underlying medical condition and reducing immunosuppression are essential to therapy. Rapid correction of metabolic abnormalities is mandatory in cases such as uncontrolled diabetes and corticosteroids or other immunosuppressive drugs should be discontinued where feasible. AmphotericinB or its newer and less toxic lipid formulations are the drugs of choice regarding antifungal chemotherapy, while extensive surgical debridemend is essential to reduce infected and necrotic tissue. A high number of cases could be prevented through measures including diabetes control programmes and proper pre- and post-surgical hygiene.

    Zygomycoses caused by fungi of the mucorales order (mucormycoses) are emerging fungal diseases with a high fatality rate. The most important risk factors include neutropenia or functional neutropenia, diabetic ketoacidosis, iron overload, major trauma, prolonged use of corticosteroids, illicit intravenous drug (ID) use, neonatal prematurity, malnourishment, and maybe a previous exposure to antifungal agents with no activity against zygomycetes, such as voriconazole and echinocandins. A high index of suspicion is crucial for the diagnosis, as prompt and appropriate management can considerably reduce morbidity and mortality. Suspicion index can be increased through recognition of the differential patterns of clinical presentation. In the non- haematological immunocompromised patients, mucormycosis can manifest in various clinical forms, depending on the underlying condition: mostly as rhino-orbital or rhino-cerebral in diabetes patients, pulmonary infection in patients with malignancy or solid organ transplantation, disseminated infection in iron overloaded or deferoxamine treated patients, cerebral - with no sinus involvement - in ID users, gastrointestinal in premature infants or malnourishment, and cutaneous after direct inoculation in immunocompetent individuals with trauma or burns.

Among 56 episodes of positive-blood cultures for B. cereus, 21 were considered significant. Median age was 54 years (range 23–82 years. Ten patients (48% had a haematologic malignancy; all were neutropenic at the time of B. cereus bacteraemia. Nonhaematologic patients were either intravenous drug users (n=3, 14%, polytraumatized (n=3, 14% or had multiple chronic comorbidities (n=5, 24%. Most episodes were hospital acquired (15, 71%. Sources of bacteraemia were intravascular catheter (n=11, 52%, digestive tract (n=6, 29%, drug injection (n=3, 14% and wound (n=1, 5%. Adequate antibiotic therapy was provided to 18 patients (86% during a median of 17 days (range 2–253 days. The intravascular catheter was removed in eight cases (42%. Three haematologic patients had a complicated course with neurologic complications (meningoencephalitis and cerebral abscesses. Complications appeared to be associated with catheter infection (100% of complicated cases vs. 29% of noncomplicated cases. In conclusion, B. cereus bacteraemia can have a complicated course in a subset of patients, mainly those with haematologic malignancy. Catheter infection may be associated with a worse outcome with frequent neurologic complications.

    Full Text Available Some haematological alterations due to active cases of tuberculosis caused by Mycobacterium tuberculosis were investigated in Enugu Urban of South East, Nigeria. The results revealed thrombocythaemia, leucocytosis and elevated Erythrocyte sedimentation rates (p and lt;0.05. There was oligocythaemia, as well as reduced haematocrit and haemoglobin concentrations (p and lt;0.05. The significant oligocythaemia, anaemia, reduced packed cell volume found in active TB positive persons are all attributed to invasion of haematopoietic organs by any of the Mycobacteria tuberculosis complex (MTBC namely: M tuberculosis, M. bovis, M africanum, M. canetti, M. microti, and M. leprae, which reduced substantially the rate of erythropoiesis. The invasion of lymphoid organs such as lymph nodes, thymus and tonsils by MTBC stimulated the synthesis of leucocytes leading to leucocytosis (p and lt;0.05. This could be an inflammatory response which prepared the victim to defend itself against any of the MTBC that invaded the lungs and might even invade other extrapulmonary organs. Thrombocythaemia in active TB is attributed to haemoptysis, since the latter occurs whenever there is a wound or a threat to tissue injury or damage. When these changes in haematological parameters are used in combination with other tests, microscopic and clinical methods, TB diagnosis and treatment could be well improved.

    Antimicrobial Stewardship Programs (ASPs) have appeared as very useful tools in order to improve the use of antimicrobial agents. The objective of this study is to assess the impact of an ASP on haematological patients hospitalized in an Intensive Care Unit (ICU). A quasi-experimental pre-post intervention study, which included haematological patients admitted to an ICU and assessed by the ASP program during 3 years. The impact of the program on patient evolution was assessed by comparison between the previous period and the intervention period in terms of mortality, mean stay, number of re-hospitalizations, and duration of mechanical ventilation for intubated patients. The ASP team assessed 324 antimicrobial agents in 169 patients; they recommended 121 modifications, including 55 treatment discontinuations. Compared with the pre-intervention period, there were no significant differences in the variables assessed. No variation was observed in colonization by multi-resistant bacteria. The implementation of an APS on critical haematological patients will lead to a relevant number of treatment modifications, without any impact on the clinical evolution of patients.

    Many patients with haematological malignancies experience barriers in clinical communication. Reaching effective communication is of great importance as it has been linked to a range of improved patient outcomes such as satisfaction, compliance to treatment, perceived quality of life and physical and mental health. To get a better understanding how communication in haematological consultations can be improved, the current study focussed on patients' preferences and perceived performances regarding the communicative behaviour of their health care professional. Secondly, the mediation of an online communication tool for patients was analysed. Within a controlled pre- post-test design, 78 datasets of clinical consultations could be analysed. Patients considered both affective and instrumental communication aspects important. The affective communication behaviour of the health care professional met the patients' pre-visit preferences well. In the information exchange, more variability and discrepancies were found. Overall, the online intervention did not seem to influence the patients' perceived communication performance of their health care professional much. To further improve the communication during clinical consultations, health care professionals should inquire about patients' expectations, especially during the exchange of information and advices. At the same time, patients should be supported to express their preferences at the start of the consultation. The study was registered in the Netherlands Trial Register, number 3779.

    Invasive mould infections (IMI) are a persistent problem with high morbidity and mortality rates among patients receiving chemotherapy for hematological malignancies and hematopoietic stem cell transplant recipients. Management of IMI in this setting has become increasingly complex with the advent of new antifungal agents and diagnostic tests, which have resulted in different therapeutic strategies (prophylactic, empirical, pre-emptive, and directed). A proper assessment of the individual risk for IMI appears to be critical in order to use the best prophylactic and therapeutic approach and increase the survival rates. Among the available antifungal drugs, the most frequently used in the hematologic patient are fluconazole, mould-active azoles (itraconazole, posaconazole and voriconazole), candins (anidulafungin, caspofungin and micafungin), and lipid formulations of amphotericin B. Specific recommendations for their use, and criteria for selecting the antifungal agents are discussed in this paper. Copyright © 2014. Published by Elsevier Espana.

    The safety of teaching off-pump coronary artery bypass grafting to trainees is best tested in high-risk patients, who are more likely to experience significant morbidity after surgery. This study compared outcomes of off-pump coronary artery bypass grafting operations performed by consultants and trainees in high-risk patients. Data for consecutive patients undergoing off-pump coronary artery bypass grafting were collected prospectively. Patients satisfying at least one of the following criteria were classified as high-risk: age older than 75 years, ejection fraction less than 0.30, myocardial infarction in the previous month, current congestive heart failure, previous cerebrovascular accident, creatinine greater than 150 micromol/L, respiratory impairment, peripheral vascular disease, previous cardiac surgery, and left main stem stenosis greater than 50%. Early morbidity, 30-day mortality, and late survival were compared. From April 1996 to December 2002, 686 high-risk patients underwent off-pump coronary artery bypass grafting revascularization. Operations by five consultants (416; 61%) and four trainees (239; 35%) were the focus of subsequent analyses. Nine visiting or research fellows performed the other 31 operations. Prognostic factors were more favorable in trainee-led operations. On average, consultants and trainees grafted the same number of vessels. There were 18 (4.3%) and 5 (1.9%) deaths within 30 days, and 14 (3.4%) and 5 (1.9%) myocardial infarctions in consultant and trainee groups, respectively. After adjusting for imbalances in prognostic factors, odd ratios for almost all adverse outcomes implied no increased risk with trainee operators, although patients operated on by trainees had longer postoperative stays and were more likely to have a red blood cell transfusion. Kaplan-Meier cumulative mortality estimates at 24-month follow-up were 10.5% (95% confidence interval, 7.7% to 14.2%) and 6.4% (95% confidence interval, 3.8% to 10.9%) in consultant

    Full Text Available Sedation is increasingly becoming a must for most endoscopic procedures. Non-anesthesiologist administration of propofol is the standard of practice in many European countries. Nevertheless, despite anesthesiology societies concerns about sedation guided by endoscopist, practitioners find some limits to propofol administration, related to high risk patients or high risk and complex procedures, which can be long lasting and technically challenging. The main patient related risk factors for sedation are elderly patients, obesity, ASA≥3 patients, individuals with craniofacial abnormalities or with pharyngolaringeal tumors, patients with an acute gastrointestinal bleeding, under pain medications, sedatives, antidepressants, or who consume significant amounts of alcohol or drugs. Procedure related risk factors have more to do with the duration and complexity of the procedure than with other factors, in which considering a general anesthesia allows the endoscopist to concentrate on a difficult task. Published papers addressing the most challenging sedation groups in endoscopy are exploring and even trespassing previously assumed frontiers, and new scenarios are opening to the endoscopist, increasing his/her autonomy, reducing costs and giving patients levels of comfort previously unknown. In this review we analyse each risk group determining the ones in which a sedation protocol could be widely applied, and other in which the published evidence does not guarantee a safe endoscopist guided propofol sedation.

The literature published between 1980 and 2013 was reviewed. Results and Conclusion. During intensive chemotherapy, vaccination turned out to be effective for hepatitis A and B, whilst vaccinations with toxoid, protein subunits, or bacterial antigens should be postponed to the less intensive phases, to achieve an adequate immune response. Apart from varicella, the administration of live-attenuated-virus vaccines is not recommended during this phase. Family members should remain on recommended vaccination schedules, including toxoid, inactivated vaccine (also poliomyelitis, and live-attenuated vaccines (varicella, measles, mumps, and rubella. By the time of completion of chemotherapy, insufficient serum antibody levels for vaccine-preventable diseases have been reported, while immunological memory appears to be preserved. Once immunological recovery is completed, usually after 6 months, response to booster or vaccination is generally good and allows patients to be protected and also to contribute to herd immunity.

  8. Patients at High-Risk for Surgical Site Infection.

    Mueck, Krislynn M; Kao, Lillian S

    Surgical site infections (SSIs) are a significant healthcare quality issue, resulting in increased morbidity, disability, length of stay, resource utilization, and costs. Identification of high-risk patients may improve pre-operative counseling, inform resource utilization, and allow modifications in peri-operative management to optimize outcomes. Review of the pertinent English-language literature. High-risk surgical patients may be identified on the basis of individual risk factors or combinations of factors. In particular, statistical models and risk calculators may be useful in predicting infectious risks, both in general and for SSIs. These models differ in the number of variables; inclusion of pre-operative, intra-operative, or post-operative variables; ease of calculation; and specificity for particular procedures. Furthermore, the models differ in their accuracy in stratifying risk. Biomarkers may be a promising way to identify patients at high risk of infectious complications. Although multiple strategies exist for identifying surgical patients at high risk for SSIs, no one strategy is superior for all patients. Further efforts are necessary to determine if risk stratification in combination with risk modification can reduce SSIs in these patient populations.

    Over 40 million surgical procedures are performed per annum in the USA and Europe, including several million patients who are considered to be high risk (Bennett-Guerrero et al 2003). Overall, the risk of death or major complications after surgery in the general surgical patient population is low, with a post-operative mortality rate of less than1% during the same hospital admission (Niskanen et al 2001).

    Pneumocystis jirovecii can cause life-threatening pneumonia following treatment for haematological malignancies or after HSCT. The mortality rate of P. jirovecii pneumonia (PCP) in these patients is 30%-60%, especially after HSCT. The clinical presentation of PCP in haematology differs from that associated with HIV infection, with the disease being acute and more often severe, having a lower fungal burden and being more frequently linked to treatment with corticosteroids. Most cases occur in patients not receiving adequate prophylaxis. The development of new therapies, including targeted treatments and monoclonal antibodies in various haematological diseases, justifies constant vigilance in order to identify new at-risk populations and give prophylaxis accordingly. The fifth and sixth European Conferences on Infections in Leukaemia (ECIL-5 and ECIL-6) aimed to review risk factors for PCP in haematology patients and to establish evidence-based recommendations for PCP diagnosis, prophylaxis and treatment. This article focuses on the magnitude of the problem, the main differences in clinical presentation between haematology patients and other immunocompromised populations, especially HIV-infected patients, and the main risk factors.

    As an alternative to the practice of obtaining repeated laboratory cultures for patients at high risk of renal impairment from recurrent UTI, a program of bone monitoring using a mail-in culture dipspoon was started. A study involving 454 children with neurogenic bladder or other urologic abnormalities showed (1) that the incidence of UTI infection in patients for whom long term antimicrobial therapy had been prescribed was not significantly lower than that in patients who were not on antimicrobials and (2) that at least 50% of dipspoons inoculated due to presentation of UTI symptoms showed no or insignificant growth. These findings suggest that need for further assessment of the efficacy of long term prophylactic antimicrobials in preventing recurrent UTI and the advisability of obtaining a urine culture result before initiating treatment when symptoms are not severe.

    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.

    In parallel to development of individualised antineoplastic treatment, scientific interest in patients' subjective theories of illness (STOI) has emerged in the oncological community. STOI depend decisively on patients' information about their disease. Coping with illness is dependent from the individual situation and context, and it is generally modulated by patients' STOI. The purpose is fivefold: (1) to provide a thorough literature review about coping and about STOI in adult haematological patients, (2) to survey through which indicators the topics were operationalized in studies, (3) to clarify the kind of coherence between these two topics, (4) to explicate the interaction between STOI and other variables, and (5) to verify the clinical relevance of both topics. We searched 19 electronic databanks for English biomedical literature manuscripts (1995-2008) on this subject. Twenty-six studies met our criteria and varied in haematological entity, treatment concept, sample size and methodological design. We conclude that a subjective-individual regulation of patient's mental stability during a cytotoxic chemotherapy is important. Successful coping strategies develop not only based on objective, but also subjective evaluation mechanisms. We deduce consequences for doctor-patient communication and psychosocial care in haematology. The newly developed process model of subjective regulation in cancer patients, in general, views the oncological treatment process as a procedural mental evaluation.

    Accurate and early identification of high-risk surgical patients allows for targeted use of perioperative monitoring and interventions that may improve their outcomes. This review summarizes current evidence on how information from the preoperative, operative, and immediate postoperative periods can help identify such individuals. Simple risk indices, such as the Revised Cardiac Risk Index or American Society of Anesthesiologists Physical Status scale, and online calculators allow risk to be estimated with moderate accuracy using readily available preoperative clinical information. Both specific specialized tests (i.e., cardiopulmonary exercise testing and cardiac stress testing) and promising novel biomarkers (i.e., troponins and natriuretic peptides) can help refine these risk estimates before surgery. Estimates of perioperative risk can be further informed by information acquired during the operative and immediate postoperative periods, such as risk indices (i.e., surgical Apgar score), individual risk factors (i.e., intraoperative hypotension), or postoperative biomarkers (i.e., troponins and natriuretic peptides). Preoperative clinical risk indices and risk calculators estimate surgical risk with moderate accuracy. Although novel biomarkers, specialized preoperative testing, and immediate postoperative risk indices show promise as methods to refine these risk estimates, more research is needed on how best to integrate risk information from these different sources.

    This study investigated the factors associated with utilization of fertility preservation and the differences in treatments and outcomes by prior chemotherapy exposure in patients with haematological diseases. This study included all 67 women with haematological diseases seen for fertility preservation consultation at two university hospitals between 2006 and 2011. Of the total, 49% had lymphoma, 33% had leukaemia, 7% had myelodysplastic syndrome and 4% had aplastic anaemia; 46% had prior chemotherapy; and 33% were planning for bone marrow transplantation, 33% pursued ovarian stimulation and 7% used ovarian tissue banking; and 48% of patients did not pursue fertility preservation treatment. All five cycle cancellations were in the post-chemotherapy group: three patients with leukaemia and two with lymphoma. Patients with prior chemotherapy had lower baseline antral follicle count (10 versus 22) and received more gonadotrophins to achieve similar peak oestradiol concentrations, with no difference in oocyte yield (10.5 versus 10) after adjustment for age. Embryo yield was similar between those who had prior chemotherapy and those who had not. Half of the patients with haematological diseases who present for fertility preservation have been exposed to chemotherapy. While ovarian reserve is likely impaired in this group, oocyte yield may be acceptable.

    2014-12-01

    We prospectively observed 36 haematological patients with mucormycosis from nine hospitals of St. Petersburg during 2004-2013. The most frequent underlying diseases were acute leukaemia (64%), and main risk factors were prolonged neutropenia (92%) and lymphocytopenia (86%). In 50% of the patients, mucormycosis was diagnosed 1-65 days after invasive aspergillosis. Main clinical form of mucormycosis was pulmonary (64%), while two or more organ involvement was noted in 50% of the cases. The most frequent aetiological agents of mucormycosis were Rhizopus spp. (48%). Twelve-week survival rate was 50%. Combination therapy (echinocandins + amphotericin B forms) and recovery from the underlying disease significantly improved the survival rate.

    Tsukamurella spp. are a rare but important cause of intravascular catheter-related bacteremia in immunocompromised patients. The organism is an aerobic, Gram-positive, weakly acid-fast bacillus that is difficult to differentiate using standard laboratory methods from other aerobic actinomycetales such as Nocardia spp., Rhododoccus spp., Gordonia spp., and the rapid growing Mycobacterium spp. We report a case of Tsukamurella tyrosinosolvens catheter-related bacteremia in a 51-year-old haematology patient who responded to treatment with imipenem and subsequent line removal. 16srRNA sequencing allowed for the prompt identification of this organism.

    2006-10-01

    Between April 2000 and May 2005, 350 bacteraemic episodes occurred among patients treated in our haematology unit. Two hundred and twenty-eight of these episodes were caused by Gram-positive pathogens, most commonly coagulase-negative staphylococci and Staphylococcus aureus. One hundred and twenty-two episodes were due to Gram-negative pathogens, with a predominance of Escherichia coli, Acinetobacter baumannii and Pseudomonas aeruginosa. Bacillus bacteraemias constituted 12 of these episodes occurring in 12 patients, and accounted for 3.4% of all bacteraemic episodes. Of the 12 strains evaluated, seven were Bacillus licheniformis, three were Bacillus cereus and two were Bacillus pumilus. Seven episodes presented with bloodstream infection, three with pneumonia, one with severe abdominal pain and deterioration of liver function, and one with a catheter-related bloodstream infection. B. licheniformis was isolated from five patients who had been hospitalized at the same time. This outbreak was related to non-sterile cotton wool used during skin disinfection. B. cereus and B. licheniformis isolates were susceptible to cefepime, carbapenems, aminoglycosides and vancomycin, but B. pumilus isolates were resistant to all antibiotics except for quinolones and vancomycin. Two deaths were observed. In conclusion, Bacillus spp. may cause serious infections, diagnostic and therapeutic dilemmas, and high morbidity and mortality in patients with haematological malignancies. Both B. cereus and B. licheniformis may be among the 'new' Gram-positive pathogens to cause serious infection in patients with neutropenia.

  3. Clostridium difficile Infections amongst Patients with Haematological Malignancies: A Data Linkage Study.

    Full Text Available Identify risk factors for Clostridium difficile infection (CDI and assess CDI outcomes among Australian patients with a haematological malignancy.A retrospective cohort study involving all patients admitted to hospitals in Western Australia with a haematological malignancy from July 2011 to June 2012. Hospital admission data were linked with all hospital investigated CDI case data. Potential risk factors were assessed by logistic regression. The risk of death within 60 and 90 days of CDI was assessed by Cox Proportional Hazards regression.There were 2085 patients of whom 65 had at least one CDI. Twenty percent of CDI cases were either community-acquired, indeterminate source or had only single-day admissions in the 28 days prior to CDI. Using logistic regression, having acute lymphocytic leukaemia, neutropenia and having had bacterial pneumonia or another bacterial infection were associated with CDI. CDI was associated with an increased risk of death within 60 and 90 days post CDI, but only two deaths had CDI recorded as an antecedent factor. Ribotyping information was available for 33 of the 65 CDIs. There were 19 different ribotypes identified.Neutropenia was strongly associated with CDI. While having CDI is a risk factor for death, in many cases it may not be a direct contributor to death but may reflect patients having higher morbidity. A wide variety of C. difficile ribotypes were found and community-acquired infection may be under-estimated in these patients.

    The initiation of systemic antimicrobial treatment of Pneumocystis jirovecii pneumonia (PCP) is triggered by clinical signs and symptoms, typical radiological and occasionally laboratory findings in patients at risk of this infection. Diagnostic proof by bronchoalveolar lavage should not delay...... and secondary anti-PCP prophylaxis is indicated in all patients thereafter. In patients with critical respiratory failure, non-invasive ventilation is not significantly superior to intubation and mechanical ventilation. The administration of glucocorticoids must be decided on a case-by-case basis....... the start of treatment. Most patients with haematological malignancies present with a severe PCP; therefore, antimicrobial therapy should be started intravenously. High-dose trimethoprim/sulfamethoxazole is the treatment of choice. In patients with documented intolerance to this regimen, the preferred...

    Invasive mould sinusitis (IMS) is a severe infection in patients with haematological malignancies. Because of a paucity of contemporaneous data about IMS, we sought to evaluate clinical aspects and outcome of IMS in these patients. The records of adult haematological malignancy patients with proven or probable IMS over a 10 year period were reviewed retrospectively. We identified 44 patients with IMS. Mucorales were isolated in 13 (35.1%) patients and Fusarium and Aspergillus were isolated in 9 (24.3%) patients each. Patients with IMS owing to Mucorales were more likely to have a history of diabetes mellitus (P = 0.003) and high-dose corticosteroid use (P = 0.03). Thirty-five (80%) patients received antifungal combinations and 36 (82%) underwent surgical debridement. The 12 week IMS-attributable mortality was 36.4% (16 patients). A relapsed and/or refractory haematological malignancy was an independent risk factor for 6 week IMS-attributable (P = 0.038), 12 week all-cause (P = 0.005) and 12 week IMS-attributable (P = 0.0015) mortality. Neutrophil count <100/µL and lymphocyte count <200/µL were associated with increased 12 week IMS-attributable and 6 week all-cause mortality, respectively (P = 0.044 and 0.013). IMS due to Aspergillus was an independent risk factor for both 12 week all-cause (P = 0.011) and IMS-attributable (P = 0.026) mortality. Initial antifungal therapy with a triazole-containing regimen was associated with decreased 6 week all-cause (P = 0.032) and IMS-attributable (P = 0.038) mortality. Surgery was not an independent factor for improved outcome. Despite combined medical and surgical therapy, IMS had high mortality. Mortality risk factors were relapsed and/or refractory malignancy, cytopenia and Aspergillus infection in this study. © The Author 2015.

    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

    Full Text Available High-risk prostate cancer (PCa, which is defined as PSA >20 ng/mL or Gleason Score (GS >7 or ≥cT3a, accounts for up to 40% of newly diagnosed cases and carries a significant risk of progression and death. However, the best management approach for patients with high-risk PCa is still under debate. Recently, radical prostatectomy (RP with extended lymphadenectomy (LND has become popular for the treatment of high-risk PCa with good prognosis in selected patients in the context of multimodal approach. However, decision should be made after all treatments have been discussed by a multidisciplinary team and the patient should be informed about the likelihood of a multimodal approach. On the other hand, necessity of sufficient surgical expertise for RP to keep the level of morbidity acceptable in high-risk PCa patients should be kept in mind.

    Retrospective studies have documented a significant association between linezolid (LNZ) plasma concentrations and drug-related haematological toxicity. However, the safe upper threshold level for LNZ plasma trough concentrations (Cmin values) has not been defined with certainty. A prospective observational study was performed aimed at comparing LNZ Cmin values in patients developing drug-related side effects with those measured in patients not experiencing LNZ toxicity. LNZ Cmin values were measured from the first week after starting therapy and were repeated periodically up to the end of treatment. Fifty patients, for a total of 210 LNZ Cmin evaluations, were considered. All patients (n=9) who developed drug-related haematological toxicity also had significantly higher plasma LNZ Cmin values during the first week of therapy (9.0±6.4 mg/L vs. 4.9±3.7 mg/L; P<0.01) and thereafter (9.3±5.4 mg/L vs. 4.4±3.4 mg/L; P<0.01). The significant association between LNZ plasma concentrations and haematological toxicity was also confirmed by multivariate logistic regression analysis including age, serum creatinine and concomitant medications as independent variables. A causal relationship between LNZ concentrations and the risk of developing drug-related haematological toxicity was observed. Accordingly, application of therapeutic drug monitoring may improve the safety outcome of patients receiving LNZ therapy.

    Full Text Available Statins are the lipid-lowering drug family of first choice in situations of hypercholesterolemia or mixed dyslipidemia with predominant increase in cholesterol. The evidence shows conclusively that each one of the commercially available statins have proven benefits on outcomes of cardiovascular morbidity and mortality. However, rosuvastatin has certain pharmacokinetic efficacy and cost-effectiveness characteristics that make it an attractive molecule to be the statin of choice in patients at high cardiovascular risk.

    The primary objective of this study was to determine the volume of distribution (Vd) (L/kg) of intravenous aminoglycosides (AGs) in critically ill haematological malignancy patients. Secondary objectives were to determine the body weight (actual, ideal, adjusted or lean) that yields the most precise estimate of Vd when normalised in L/kg as well as the frequency that current first-dose strategies result in post-distributional peak concentrations (C(peak)) within the target range (tobramycin 16-24 mg/L; amikacin 32-48 mg/L). In total, 58 AG doses were included (tobramycin, n = 34; amikacin, n = 24). Median Vd was 0.38 L/kg normalised per the most precise dose weight, which was actual body weight (ABW). The median dose was 445 mg (5.8 mg/kg ABW) for tobramycin and 1200 mg (13.8 mg/kg ABW) for amikacin. Target C(peak) (tobramycin 20mg/L; amikacin 40 mg/L) was achieved in only 25% of all AG episodes, with 4% exceeding the target and 71% falling below the target. Twenty-four organisms were isolated in the study sample; target C(peak) achievement (tobramycin 20 mg/L; amikacin 40 mg/L) would yield a peak:minimum inhibitory concentration of 10 in 75% and 52% of organisms, respectively. In conclusion, an increased Vd of AGs was identified in this critically ill haematological malignancy patient sample, and current dosing yielded a suboptimal C(peak) in the majority of patients.

  6. Identifying patients at high risk of tuberculosis recurrence

    Directory of Open Access Journals (Sweden)

    Full Text Available Several studies have been done in relation to recurrence of tuberculosis (TB following completion of treatment. However, recurrence of TB is still a major problem from a public health perspective in high-burden countries, where no special attention is being given to this issue. Disease recurrence is an important indicator of the efficacy of antituberculosis treatment. The rate of recurrence is highly variable and has been estimated to range from 4.9% to 25%. This variability is not only a reflection of regional epidemiology of recurrence but differences in the definitions used by the TB control programs. In addition to treatment failure related to medication adherence, there are several key host factors that are associated with high rates of recurrence. The widely recognized host factors independent of treatment program that predispose to TB recurrence include: malnutrition; human immunodeficiency virus; substance abuse including tobacco use; comorbidity such as diabetes, renal failure and systemic diseases, especially immunosuppressive states; and environmental exposure such as silicosis. With improved understanding of the human genome, proteome, and metabolome, additional host-specific factors that predispose to recurrence are being discovered. Information on temporal and geographical trends of TB cases as well as genotyping might provide further information to enable us to fully understand TB recurrence and discriminate between reactivation and new infection. The recently launched World Health Organization End TB Strategy emphasizes the importance of integrated, patient-centered TB care. Continued improvement in diagnosis, treatment approaches, and defining host-specific factors are needed to fully understand the clinical epidemiological and social determinants of TB recurrence.

    To evaluate the efficiency and safety of carvedilol treatment in high risk hypertensive patients. Carvedilol was administered in 379 hypertensive patients with high risk factors such as NIDDM, lipid disorders or abnormal serum creatinine level and 364 primary hypertensive patients without risk factors. Before and after treatment with carvedilol, blood pressure, heart rate, serum glucose, lipid profile and serum creatinine level were tested. After treatment, the blood pressure and heart rate were reduced significantly and there was no difference between the two groups. After treatment, the serum glucose, TC, TG and LDL in the high risk group, were reduced from 6.13, 5.37, 2.29 mmol/L and 3.04 to 5.80, 5.11, 2.05 and 2.87 mmol/L respectively (P hypertensive group after treatment from 4.73 mmol/L to 4.69 mmol/L (P high risk group and the primary hypertensive group was 97.75% and 98.32%; there is no statistical difference. The efficiency and safety of carvedilol in the high risk hypertensive patients is same as in the primary hypertensive patients.

    Full Text Available Prostate cancer (PC is one of the most burning problems of modern urologic oncology. Patients at its high risk are characterized by a more aggressive course of the disease and significantly lower tumor-specific and relapse-free survival rates. Hormone therapy and radiotherapy are one of the conventional treatments in patients with PC at high risk of progression. Nonetheless, more and more publications demonstrating the efficiency and safety of surgical therapy in this contingent of patients are recently appearing. This paper presents the results of surgical treat-ment in 499 patients with PC at high risk of progression, who have undergone radical prostatectomy with extended pelvic lymphadenectomy at the Department of Urologic Oncology, P.A.

    Our objective was to compare the effectiveness of percutaneous cholecystostomy (PC) vs conservative treatment (CO) in high-risk patients with acute cholecystitis. The study was randomized and comprised 123 high-risk patients with acute cholecystitis. All patients fulfilled the ultrasonographic criteria of acute inflammation and had an APACHE II score {>=}12. Percutaneous cholecystostomy guided by US or CT was successful in 60 of 63 patients (95.2%) who comprised the PC group. Sixty patients were conservatively treated (CO group). One patient died after unsuccessful PC (1.6%). Resolution of symptoms occurred in 54 of 63 patients (86%). Eleven patients (17.5%) died either of ongoing sepsis (n=6) or severe underlying disease (n=5) within 30 days. Seven patients (11%) were operated on because of persisting symptoms (n=3), catheter dislodgment (n=3), or unsuccessful PC (n=1). Cholecystolithotripsy was performed in 5 patients (8%). Elective surgery was performed in 9 cases (14%). No further treatment was needed in 32 patients (51%). In the CO group, 52 patients (87%) fully recovered and 8 patients (13%) died of ongoing sepsis within 30 days. All successfully treated patients showed clinical improvement during the first 3 days of treatment. Percutaneous cholecystostomy in high-risk patients with acute cholecystitis did not decrease mortality in relation to conservative treatment. Percutaneous cholecystostomy might be suggested to patients not presenting clinical improvement following 3 days of conservative treatment, to critically ill intensive care unit patients, or to candidates for percutaneous cholecystolithotripsy.

    Patients with chronic lymphocytic lymphoma (CLL) with high-risk cytogenetics [del(11q)(q22.3) or del(17p)(p13.1)] have limited therapeutic options and their prognosis remains poor. This analysis was conducted to determine the clinical activity of lenalidomide in patients with high-risk disease. Relapsed/refractory patients with CLL enrolled in a phase II clinical trial who had del(11q)(q22.3) or del(17p)(p13.1) were included in this analysis. Patients received single agent lenalidomide for 21 days of the 4 week treatment cycle. The overall response rate among patients with high-risk cytogenetics was 38%, with 19% of patients achieving a complete response. Median progression-free survival was 12.1 months, which is higher than demonstrated with other agents in comparable patient populations. In addition, the estimated 2-year survival probability was 58%, demonstrating that the responses achieved with lenalidomide are durable, even in patients with CLL with high-risk disease with poor risk cytogenetics.

    Since two large-scale, randomised studies on posaconazole prophylaxis have demonstrated a clear benefit for patients at high risk for contracting invasive fungal disease (IFD), posaconazole prophylaxis has been adopted as standard of care for this patient collective. Several years on from implementation at our institution, we wanted to evaluate its impact on the incidence and use of empirical antifungal therapy in a real-life setting. We analysed retrospectively incidence and severity of IFD in high-risk patients with prophylaxis, using a historical cohort as comparator. A total of 200 patients had either received the extended spectrum triazole posaconazole in prophylactic dosage of 200 mg tid or empirical antifungal therapy. Disease events were analysed by application of the revised EORTC/MSG definitions for IFD. Before posaconazole prophylaxis, we recorded 57/100 cases of IFD which was reduced to 28/100 with prophylaxis. The empirical use of antifungal drugs was reduced to 41% from 91% in the non-prophylaxis cohort. Furthermore, we observed a shift in the categorisation of IFD according to EORTC/MSG criteria. Our data suggest that posaconazole was effective in reducing the rate and probability of invasive fungal disease in high-risk patients.

    Full Text Available Abstract Background The percentage of hypertrophic cardiomyopathy (HCM patients who are in high risk for Sudden Death (SD constitutes only a minority of all HCM population but the incidence of SD in this subset is high (at least 5% annually. The identification of this small but important proportion of high risk HCM patients has been the clue in the clinical evaluation of these patients. Methods Our study cohort consisted from 123 patients with HCM who are currently followed up in our Institution. Five clinical risk factors were assessed: a family history of premature SD, unexplained syncope, Non Sustained Ventricular Tachycardia (NSVT on 24-h ECG monitoring, Abnormal Blood Pressure Response (ABPR during upright exercise testing and Maximum left ventricular Wall Thickness (MWT ≥30 mm. The purpose of our study was the identification of high risk HCM patients coming from Northern Greece. Results Fifteen patients (12.2% of the whole cohort had MWT ≥ 30 mm, 30 patients (24.4% had an ABPR to exercise, 17 patients (13.8% had episodes of NSVT in 24-h Holter monitoring, 17 patients (13.8% suffered from syncope, and 8 patients (6.5% had a positive family history of premature SD. Data analysis revealed that 74 patients (60.1% had none risk factor. Twenty four patients (19.5% had 1 risk factor, 17 patients (13.8% had 2 risk factors, 4 patients (3.25% had 3 risk factors, and 4 patients (3.25% had 4 risk factors, while none patient had 5 risk factors. Twenty five patients (20.3% had 2 or more risk factors. Conclusion This study for the first time confirms that, although a 60% of patients with HCM coming from a regional Greek population are in low risk for SD, a substantial proportion (almost 20% carries a high risk for SD justifying prophylactic therapy with amiodaron or ICD implantation.

    In the international literature, the most commonly recommended intervention for managing oral mucositis is good oral care, assuming that nurses have sufficient knowledge and skills to perform oral care correctly. The aim of the present study was to investigate if knowledge and skills about oral care improve when education in oral care is provided to nurses in charge of patients who are at risk of oral mucositis. This intervention study consists of a baseline test on the knowledge and skills of nurses of the haematology wards of two different hospitals. Oral care education sessions were given in one hospital and follow-up tests were performed in both hospitals. Nursing records were examined and observations of nurses performing oral care were made at baseline as well as at follow-up. The results show significant differences in the scores for knowledge and skills before and after the education, whereas there was no difference in scores at the two points in time for the comparison hospital, where no education had taken place. The records test showed no differences at baseline or follow-up for the two groups. Observations showed that nurses who followed the education session implemented the oral care protocol considerably better than those who did not attended. Education in oral care has a positive influence on the knowledge and skills of nurses who care for patient at risk of oral mucositis, but not on the quality of oral care documentation.

    Patients with STOP-BANG score >3 have a high risk of Obstructive sleep apnea. The aim of this study was to evaluate early postoperative respiratory complications in adults with STOP-BANG score >3 after general anesthesia. This is a prospective double cohort study matching 59 pairs of adult patients with STOP-BANG score >3 (high risk of obstructive sleep apnea) and patients with STOP-BANG score <3 (low risk of obstructive sleep apnea), similar with respect to gender, age and type of surgery, admitted after elective surgery in the Post-Anaesthesia Care Unit in May 2011. Primary outcome was the development of adverse respiratory events. Demographics data, perioperative variables, and postoperative length of stay in the Post-Anesthesia Care Unit and in hospital were recorded. The Mann-Whitney test, the chi-square test and the Fisher exact test were used for comparisons. Subjects in both pairs of study subjects had a median age of 56 years, including 25% males, and 59% were submitted to intra-abdominal surgery. High risk of obstructive sleep apnea patients had a higher median body mass index (31 versus 24kg/m(2), p<0.001) and had more frequently co-morbidities, including hypertension (58% versus 24%, p<0.001), dyslipidemia (46% versus 17%, p<0.001) and insulin-treated diabetes mellitus (17% versus 2%, p=0.004). These patients were submitted more frequently to bariatric surgery (20% versus 2%, p=0.002). Patients with high risk of obstructive sleep apnea had more frequently adverse respiratory events (39% versus 10%, p<0.001), mild to moderate desaturation (15% versus 0%, p=0.001) and inability to breathe deeply (34% versus 9%, p=0.001).

    To demonstrate the patterns of breast cancer-specific mortality (BCSM) in estrogen receptor (ER)-positive diseases and to identify high-risk candidates for extended endocrine therapy. Using the Surveillance, Epidemiology and End Results database, we identified ER-positive patients diagnosed between 1990 and 2000 (cohort 1 [C1]) and between 2001 and 2005 (cohort 2 [C2]). The patterns of BCSM were calculated using Cox proportional hazard regression models. A risk classification model was developed, and X-tile software was used to divide patients with high BCSM rates into 3 risk groups. The annual BCSM rate of C2 was decreased by one-third and was maintained at 10-15 (per 1000 persons per year) from year 2 to year 10. Long-term mortality risks still persisted in C2, especially in patients with node-positive, grade 3 or T3 disease, who should be considered as "clinical-high-risk". These patients were further divided into 3 risk groups through our model: for C1, 42.2% were in the low-risk group, 38.9% in the medium-risk group, and 18.9% in the high-risk group; and for C2, 45.5% were in the low-risk group, 38.2% in the medium-risk group and 16.2% in the high-risk group (p risk group. ER-positive patients with node-positive, grade 3 or T3 diseases had sustained risks of death throughout the 10-year time frame, and our model is helpful to identify patients with high risk who are candidates for extended endocrine therapy.

    Full Text Available Background: There are some conflicting results with Conventional Coronary Artery Bypass Grafts (CCABG with arrested heart in coronary high-risk patients. Moreover, performing off-pump CABG in these cases may be associated with serious complications. The objective of this study is to evaluate the efficacy of the on-pump beating CABG (OPBCABG in coronary high-risk patients in comparison with the conventional methods. Methods: In a prospective research study, 3000 off-pump CABG patients were considered during June 2003 to December 2011. Among these, 157 patients with one or more of the following risk factors were included for OPBCABG; severe left main stenosis, early post-acute myocardial infarction with ongoing chest pain, unstable angina, intractable ventricular arrhythmia, post complicated coronary intervention and severe left ventricular dysfunction. These patients were compared with 157 similar patients undergone CCABG with aortic cross clamp before 2003. Results: Preoperative patient characteristics revealed no significant differences between the two groups. The patients’ mean age and number of grafts were 57 years and 3 per patient respectively. Hospital mortality was 3.2% and 9% in OPBCABG and CCABG groups, respectively (P<0.001. Preoperative myocardial infarction, requirement of inotropic agents and intraaortic balloon pump, renal dysfunction and prolonged ventilation time were significantly higher in CCABG group. Conclusion: Our results suggest that OPBCABG is effective in coronary high-risk patients and significantly reduces mortality and the incidence of perioperative MI and other major complications.

    Severe forms of acute respiratory distress syndrome in patients with haematological diseases expose clinicians to specific medical and ethical considerations. We prospectively followed 143 patients with haematological malignancies, and whose lungs were mechanically ventilated for more than 24 h, over a 5-y period. We sought to identify prognostic factors of long-term outcome, and in particular to evaluate the impact of the severity of acute respiratory distress syndrome in these patients. A secondary objective was to identify the early (first 48 h from ICU admission) predictive factors for acute respiratory distress syndrome severity. An evolutive haematological disease (HR 1.71; 95% CI 1.13-2.58), moderate to severe acute respiratory distress syndrome (HR 1.81; 95% CI 1.13-2.69) and need for renal replacement therapy (HR 2.24; 95% CI 1.52-3.31) were associated with long-term mortality. Resolution of neutropaenia during ICU stay (HR 0.63; 95% CI 0.42-0.94) and early microbiological documentation (HR 0.62; 95% CI 0.42-0.91) were associated with survival. The extent of pulmonary infiltration observed on the first chest X-ray and the diagnosis of invasive fungal infection were the most relevant early predictive factors of the severity of acute respiratory distress syndrome. © 2016 The Association of Anaesthetists of Great Britain and Ireland.

    Compliance of physicians with guidelines has emerged as an important indicator for quality of care. We evaluated compliance of physicians with adjuvant therapy guidelines for endometrial cancer patients in the Netherlands in a population-based cohort over a period of 10years. Data from all patients diagnosed with endometrial cancer between 2005 and 2014, without residual tumor after surgical treatment, were extracted from the Netherlands Cancer Registry (N=14,564). FIGO stage, grade, tumor type and age were used to stratify patients into risk groups. Possible changes in compliance over time and impact of compliance on survival were assessed. Patients were stratified into low/low-intermediate (52%), high-intermediate (21%) and high (20%) risk groups. Overall compliance with adjuvant therapy guidelines was 85%. Compliance was highest in patients with low/low-intermediate risk (98%, no adjuvant therapy indicated). The lowest compliance was determined in patients with high risk (61%, external beam radiotherapy with/without chemotherapy indicated). Within this group compliance decreased from 64% in 2005-2009 to 57% in 2010-2014. In high risk patients with FIGO stage III serous disease compliance was 55% (chemotherapy with/without radiotherapy indicated) and increased from 41% in 2005-2009 to 66% in 2010-2014. While compliance of physicians with adjuvant therapy guidelines is excellent in patients with low and low-intermediate risk, there is room for improvement in high risk endometrial cancer patients. Eagerly awaited results of ongoing randomized clinical trials may provide more definitive guidance regarding adjuvant therapy for high risk endometrial cancer patients. Copyright © 2017 Elsevier Inc.

    Full Text Available Objective To review the high-risk prostate cancer (PCa patient database with special emphasis on the role of radical prostatectomy (RP in comparison to external beam radiotherapy (EBRT. Materials and Methods A total of 102 patients with complete and long-term follow-up data were included. High-risk PCa was defined as: a pre-treatment PSA level of ≥20 ng/mL and/or a primary Gleason score of ≥4 and/or clinical stage ≥T3N0M0 disease. A total of 45 (42.5% patients underwent radical RP with extended pelvic lymphadenectomy for-high risk PCa and a total of 57 (53.8% patients received EBRT. Results The mean overall survival (mean survival 95.2 vs. 129.2 months, log rank p=0.73 and cancer-specific survival (mean survival 104 vs. 151.4 months, log rank p=0.35 were not significantly different between RP and EBRT groups. Univariate analysis of variables that may affect overall survival showed no significant effect of pre-treatment PSA, Gleason score, clinical stage or type of therapy. The only factor which reached statistical significance was patient age (p=0.002. Multivariate analysis of variables also showed no significant effect of pre-treatment PSA, Gleason score, clinical stage or type of therapy and, again, the only factor which reached statistical significance was patient age (p=0.012. Conclusion Radical prostatectomy appears to be an effective and a non-inferior treatment option in patients with high-risk localized PCa with acceptable overall and cancer-specific survival compared to RT. Therefore, as the guidelines suggest, it should be provided as an option during patient consultation for a proper informed decision-making.

    Full Text Available The use of simple and economic tests to rule out diseases of sufficient clinical severity is appealing in emergency department (ED, since it would be effective for contrasting ED overcrowding and decreasing healthcare costs. The aim of this study was to assess the diagnostic performance of simple and economic haematological testing in a large sample of adult patients presenting at the ED of the Academic Hospital of Parma during the year 2010 with the five most frequent acute pathologies (i.e., acute myocardial infarction, renal colic, pneumonia, trauma and pancreatitis. Both leukocyte count and hemoglobin showed a good diagnostic performance (Area Under the Curve [AUC] of 0.85 for leukocyte count and 0.76 for hemoglobin; both p < 0.01. Although the platelet count was significantly increased in all patients groups except pancreatitis, the diagnostic performance did not achieve statistical significance (AUC 0.53; p = 0.07. We also observed an increased RDW in all groups, except in those with trauma and the diagnostic performance was acceptable (AUC 0.705; p < 0.01. The mean platelet volume (MPV was consistently lower in all patients groups and also characterized by an efficient diagnostic performance (AUC 0.76; p < 0.01. This evidence led us to design an arbitrary formula, whereby MPV and hemoglobin were multiplied, and further divided by the leukocyte count, obtaining a remarkable AUC (0.91; p < 0.01. We conclude that simple, rapid and cheap hematological tests might provide relevant clinical information for decision making to busy emergency physicians, and the their combination into an arbitrary formula might further increase the specific diagnostic potential of each of them.

    Objective: To assess the value of breast MRI in size assessment of breast cancers in high risk patients, including those with a BRCA 1 or 2 mutation. Guidelines recommend invariably breast MRI screening for these patients and therapy is thus based on these findings. However, the accuracy of breast MRI for staging purposes is only tested in sporadic cancers. Methods: We assessed concordance of radiologic staging using MRI with histopathology in 49 tumors in 46 high risk patients (23 BRCA1, 12 BRCA2 and 11 Non-BRCA patients). The size of the total tumor area (TTA) was compared to pathology. In invasive carcinomas (n = 45) the size of the largest focus (LF) was also addressed. Results: Correlation of MRI measurements with pathology was 0.862 for TTA and 0.793 for LF. TTA was underestimated in 8(16%), overestimated in 5(10%), and correctly measured in 36(73%) cases. LF was underestimated in 4(9%), overestimated in 5(11%), and correctly measured in 36(80%) cases. Impact of BRCA 1 or 2 mutations on the quality of size estimation was not observed. Conclusions: Tumor size estimation using breast MRI in high risk patients is comparable to its performance in sporadic cancers. Therefore, breast MRI can safely be used for treatment planning.

    Context. The use of thiazolidinediones (TZDs) in patients with type-2 diabetes mellitus appears to be associated with an increased risk of myocardial infarction (MI) compared with placebo or other oral antidiabetic drug regimens. Objective. We conducted a study to investigate whether there was a difference in the risk of acute MI and hemorrhagic and non-hemorrhagic stroke between specific TZDs, namely rosiglitazone maleate (Avandia) and pioglitazone (Actos), and other oral antidiabetic agents in a high-risk, largely underrepresented and largely minority Medicaid population. Study Design, Setting, and Patients. We analyzed patient encounter data using propensity-scoring methods and logistic regression to compare the risk of cardiovascular (CV) events in patients with type-2 diabetes in a high-risk population. Main Outcome Measures. Outcomes were identified through International Classification of Disease (ICD-9) codes 410–411 for acute MI; 430–438 for stroke; and revenue (emergency department) codes 450–459 in the case of MI. Results. Using retrospective medical encounter and prescription data analyses, we found that rosiglitazone, compared with other oral antidiabetic agents, was associated with an increased rate of CV events by 20% in a high-risk cohort of diabetic patients. Neither pioglitazone nor the TZD drug class as a whole was associated with an increased CV risk. Conclusion. Rosiglitazone was associated with a significant increase in CV events (MI and stroke) among high-risk patients with type-2 diabetes, whereas pioglitazone was not. We recommend further research to capture risk factors that were not observed in our encounter data. PMID:20140111

    Treatment of recurrent sigmoid volvulus is a major challenge in frail and elderly patients with multiple co-morbidities. Early management involves endoscopic decompression with high success rate, however, its recurrence make it a real challenge as most of these patients are not suitable for major colonic resection. The aim of this study was to assess the role of percutaneous endoscopic colostomy (PEC) in the treatment of recurrent sigmoid volvulus in these patients. Twelve PEC procedures were performed in 8 patients under our care. This prevented major colonic resection in 7 patients. One patient underwent sigmoid resection and died with postoperative complications. Two patients experienced minor complications. Three patients required repeat procedures for permanent PEC tube placement. Six patients managed permanently with PEC procedure. PEC is an effective treatment for recurrent sigmoid volvulus in high-risk elderly patients.

    Aim: To evaluate the safety and efficacy of transcatheter arterial chemo-lipiodol infusion (TACL) in high-risk patients with unresectable hepatocellular carcinoma (HCC). Materials and methods: From January 2005 to April 2009, 96 patients underwent TACL. All patients had diffuse, infiltrative or multifocal tumours. Twenty-nine (30%) patients had an increased serum bilirubin level (>=2 mg/dl), and 75 patients (78%) had a low serum albumin level (<3.5 mg/dl). The Child-Pugh (CP) score was 9 or more in 13 (14%) patients. Sixty-five patients (68%) had major portal vein occlusion. Sixteen patients (17%) had biliary dilatation. Results: TACL was technically successful in all patients. After TACL, 18 (19%) of the 96 patients showed tumour response using computed tomography (CT) criteria. The 30 day mortality and morbidity rates were 1 and 2%, respectively. The median survival period was 8.6 months, and the overall 6 month, 1, 2, and 3 year survival rates were 59, 44, 26, and 15%, respectively. Portal vein occlusion (p < 0.001) was the only significant risk factor associated with the length of the survival period after TACL, whereas the CP score (p = 0.498), serum bilirubin level (p = 0.153), serum albumin level (p = 0.399), and biliary obstruction (p = 0.636) had no significant effect. Conclusions: TACL can be performed safely in high risk HCC patients resulting in a median survival rate of 8.6 months in the present series.

    BACKGROUND: Performance of endoscopy within 24 h is recommended for patients with acute nonvariceal upper gastrointestinal bleeding (ANVUGIB). It is unknown whether performing endoscopy early within this 24 h window is beneficial for clinically high-risk patients. METHODS: A retrospective review was performed to identify patients presenting to two tertiary care centres with ANVUGIB and either systolic blood pressure lower than 100 mmHg or heart rate greater than 100 beats/min on presentation between 1999 and 2004. Patients receiving endoscopy within 6 h (rapid endoscopy [RE]) were compared with patients undergoing endoscopy between 6 h and 24 h (early endoscopy [EE]). The primary outcome measure was the development of any adverse bleeding outcome (rebleeding, surgery for control of bleeding, in-hospital mortality or readmission within 30 days for ANVUGIB). RESULTS: There were 169 patients who met the entry criteria (77 RE patients and 92 EE patients). There was no significant difference in the development of any adverse bleeding outcomes between RE and EE patients (25% RE versus 23% EE, difference between groups 2%, 95% CI −9% to 13%). Transfusion requirements and length of hospital stay also did not differ between the comparator groups. RE was not associated with fewer adverse outcomes, even after adjusting for confounders. CONCLUSION: For clinically high-risk ANVUGIB patients, performing endoscopy within 6 h of presentation is no more effective than performing endoscopy between 6 h and 24 h after presentation. The role of RE in high-risk ANVUGIB patients requires further delineation in a prospective fashion. PMID:17637943

    Low-density lipoprotein (LDL)-cholesterol levels are strictly related to the risk of major cardiovascular events. Statins have been demonstrated to significantly reduce LDL-cholesterol levels, contributing to cardiovascular risk reduction especially in high-risk patients. However, low adherence to statins, due to adverse effects, is often observed and many patients in secondary prevention exhibit LDL-cholesterol levels >70 mg/dl. As a consequence, there is the need for new therapeutic approaches with different mechanisms of action to reach recommended lipid targets in high-risk patients. One potential approach is to inhibit PCSK9, a serum protein with an active role in controlling the expression of LDL receptors, by reducing their recycling and targeting it for lysosomal destruction. Monoclonal antibodies against PCSK9, in particular alirocumab and evolocumab, have been shown to reduce LDL substantially, either with or without concomitant statin therapy with good tolerability. Ongoing trials will further define the efficacy of these drugs as an emerging approach to the treatment of hypercholesterolemia in primary and secondary prevention of high-risk patients.

    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.

    In the absence of a standardized safe surgical reentry strategy for high-risk patients with large or anterior postoperative aortic false aneurysm (PAFA), we aimed to describe an effective and safe approach for such patients. We prospectively analyzed patients treated for PAFA between 2006 and 2015. According to the preoperative computed tomography scan examination, patients were divided into two groups according to the anatomy and extension of PAFA: in group A, high-risk PAFA (diameter ≥3 cm) developed in the anterior mediastinum; in group B, low-risk PAFA (diameter <3 cm) was situated posteriorly. For group A, a safe surgical strategy, including continuous cerebral, visceral, and coronary perfusion was adopted before resternotomy; group B patients underwent conventional surgery. We treated 27 patients (safe reentry, n = 13; standard approach, n = 14). Mean age was 60 years (range, 29 to 80); 17 patients were male. Mean interval between the first operation and the last procedure was 4.3 years. Overall 30-day mortality rate was 7.4% (1 patient in each group). No aorta-related mortality was observed at 1 and 5 years in either group. The Kaplan-Meier overall survival estimates at 1 and 5 years were, respectively, 92.3% ± 7.4% and 73.4% ± 13.4% in group A, and 92.9% ± 6.9% and 72.2% ± 13.9% in group B (log rank test, p = 0.830). Freedom from reoperation for recurrent aortic disease was 100% at 1 year and 88% at 5 years. The safe reentry technique with continuous cerebral, visceral, and coronary perfusion for high-risk patients resulted in early and midterm outcomes similar to those observed for low-risk patients undergoing conventional surgery.

    BACKGROUND: Acute high-risk abdominal (AHA) surgery carries a very high risk of morbidity and mortality and represents a massive healthcare burden. The aim of the present study was to evaluate the effect of a standardized multidisciplinary perioperative protocol in patients undergoing AHA surgery...... after initiation of the AHA protocol as standard care. The intervention cohort was compared with a predefined, consecutive historical cohort of patients from the same department. The protocol involved continuous staff education, consultant-led attention and care, early resuscitation and high......-dose antibiotics, surgery within 6 h, perioperative stroke volume-guided haemodynamic optimization, intermediate level of care for the first 24 h after surgery, standardized analgesic treatment, early postoperative ambulation and early enteral nutrition. The primary outcome was 30-day mortality. RESULTS: Six...

    We describe a novel surgical technique with a median sternotomy closure in high-risk open heart patients. In contrast to conventional sternal closure, in which sternal wires are passed through the intercostal space, the novel technique in sternal closure passes sternal wires transcostally or through costo-chondral joints.

    To explore the association between vitamin B12 deficiency and dementia in patients at high risk for vitamin B12 deficiency. Chart review. Emergency, critical care/ trauma, neurology, medicine, and rehabilitation units of two hospitals in Southwestern Ontario, Canada. Adult patients (n = 666) admitted from 2010 to 2012. Data collection included: reason for admission, gender, age, clinical signs and symptoms of B12 deficiency, serum B12 concentration, and B12 supplementation. Patients with dementia were identified based on their medication profile and medical history. Vitamin B12 deficiency (pmol/L) was defined as serum B12 concentration 220. Comparisons between B12-deficient patients with and without dementia were examined using parametric and non-parametric tests. Serum B12 values were available for 60% (399/666) of the patients, of whom 4% (16/399) were B12-deficient and 14% (57/399) were marginally deficient. Patients with dementia were not more likely to be B12-deficient or marginally deficient [21% (26/121)] compared to those with no dementia [17% (47/278), p=0.27)]. Based on documentation, 34% (25/73) of the B12-deficient and marginally-deficient patients did not receive B12 supplementation, of whom 40% (10/25) had dementia. In this sample of patients, there was no association between B12 deficiency and dementia. However, appropriate B12 screening protocols are necessary for high risk patient to identify deficiency and then receive B12 supplementation as needed.

    Full Text Available 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.

    Radiocontrast nephropathy (RCN) is a common and costly form of acute renal failure. Current preventative strategies include the use of intravenous (IV) fluids and the discontinuation of nephrotoxic medications at the time of radiocontrast administration. We sought to determine whether providers employ these strategies in high-risk patients to limit the development of RCN. High-risk patients undergoing procedures using radiocontrast media over a 12-month period were identified. Medical records were reviewed for all subjects who developed RCN and a randomly selected 25% of patients without RCN. Patients with a contraindication to IV volume expansion were excluded. Medical records of the remaining patients were reviewed to determine whether IV fluids were administered and whether NSAIDs or COX-2 inhibitors were prescribed at the time of contrast administration. RCN developed in 8% of patients overall. Of 144 patients eligible for IV volume expansion, 16% failed to receive any IV fluids. When IV fluids were employed, their dose and timing of administration varied significantly by treating specialty and procedure. NSAIDs and COX-2 inhibitors were prescribed to 8% of patients. Commonly accepted strategies for the prevention of RCN are underutilized. Quality improvement efforts are needed to increase the use of these two simple prophylactic measures. Copyright 2004 S.

    2010-01-01

    An intervention using heel pressure ulcer and plantar flexion contracture prevention protocols for high-risk patients was established to promote earlier recognition of heel skin issues and provide effective prevention of both conditions. Fifty-three patients who were sedated, managed in an intensive care unit for 5 days or more, and had a Braden Scale score of 16 or less were treated with heel protector devices that maintained the foot in a neutral position and floated the heel off the bed. On admission to the intensive care unit, heel skin assessment and the Braden Scale were administered to all patients. Initial ankle range of motion was measured with a goniometer on admission and before the application of the heel protector. Goniometric measurements were documented every other day. Heel assessments and the Braden Scale for Predicting Pressure Sore Prevention and Ramsay Sedation Scale scores were recorded in every shift and recorded as part of the study every other day. Measurements continued until the patient was transferred, the heel protector boot was discontinued by the physician, or the patient's Braden Scale score rose above 16. Application of the heel protectors led to a 50% reduction in prevalence of abnormal heel position. No patients developed plantar flexion contractures or new heel ulcers. Patients with normal heels had significantly higher Braden Scale scores compared to those with abnormal heels (P 5 .0136). Despite their high risk, no patients using the heel protector device developed a heel pressure ulcer or plantar flexion contracture.

    Full Text Available Urinary podocyte (podocyturia has been studied as a diagnostic marker for preeclampsia. We sought to validate its use in preeclampsia and in differentiating it from other high risk pregnancy states. We studied an obstetric population at high risk to develop preeclampsia (study group and uncomplicated pregnancies (control group by analyzing their urine sediment for podocytes within 24 hours of delivery. Podocytes were identified by immunohistochemistry using the podocyte-specific protein synaptopodin. Of the 56 patients who were enrolled, 29 patients were diagnosed with preeclampsia, 9 patients had hypertensive conditions such as chronic and gestational hypertension, 6 patients had Type I/II and gestational diabetes mellitus, 3 patients were classified as others, and 9 patients exhibited uncomplicated pregnancies. Podocyturia was identified in 11 out of 29 (38% of patients with preeclampsia/eclampsia, 3 out of 9 (33% with gestational and chronic hypertension, and 3 out of 6 (50% with Type I/II and gestational diabetes mellitus. None of the 9 patients (0% with uncomplicated pregnancies demonstrated podocyturia. The sensitivity and specificity of podocyturia for preeclampsia were found to be 38% and 70%. Our study showed that podocyturia does not appear to be a sensitive nor a specific marker to diagnose preeclampsia.

    2011-01-01

    Background Patients with schizophrenia have a decreased ability to interpret the intentions of other individuals, called Theory of Mind (ToM). As capacity for ToM normally advances with brain maturation, research on ToM in individuals at heightened clinical risk for psychosis may reveal developmental differences independent of disease based differences. Methods We examined ToM in at clinical high risk and schizophrenia patients as well as healthy controls: 1) 63 clinical high risk (CHR) patients and 24 normal youths ascertained by a CHR program; and 2) in 13 schizophrenia cases and 14 normal adults recruited through a schizophrenia program. ToM measures included first- and second-order false belief cartoon tasks (FBT) and two “higher order” tasks (“Strange Stories Task” (SST) and the “Reading the Mind in the Eyes” task). In the first study, CHR patients and normal youths were also assessed for cognition, “prodromal” symptoms and social function. Results Errors on first- and second-order false belief tasks were made primarily by patients. CHR patients and their young comparison group had equivalent performance on higher order ToM, which was not significantly different from the worse ToM performance of schizophrenia patients and the higher performance of normal adult controls. In the combined dataset from both studies, all levels of ToM were associated with IQ, controlling for age and sex. ToM bore no relation to explicit memory, prodromal symptoms, social function, or later transition to psychosis. Conclusions Higher order ToM capacity was equally undeveloped in high risk cases and younger controls, suggesting performance on these tasks is not fully achieved until adulthood. This study also replicates the association of IQ with ToM performance described in previous studies of schizophrenia. PMID:21757324

    This study sought to develop a clinical model that identifies patients with and without high-risk coronary artery disease (CAD). Although current clinical models help to estimate a patient's pre-test probability of obstructive CAD, they do not accurately identify those patients with and without high-risk coronary anatomy. Retrospective analysis of a prospectively collected multinational coronary computed tomographic angiography (CTA) cohort was conducted. High-risk anatomy was defined as left main diameter stenosis ≥50%, 3-vessel disease with diameter stenosis ≥70%, or 2-vessel disease involving the proximal left anterior descending artery. Using a cohort of 27,125, patients with a history of CAD, cardiac transplantation, and congenital heart disease were excluded. The model was derived from 24,251 consecutive patients in the derivation cohort and an additional 7,333 nonoverlapping patients in the validation cohort. The risk score consisted of 9 variables: age, sex, diabetes, hypertension, current smoking, hyperlipidemia, family history of CAD, history of peripheral vascular disease, and chest pain symptoms. Patients were divided into 3 risk categories: low (≤7 points), intermediate (8 to 17 points) and high (≥18 points). The model was statistically robust with area under the curve of 0.76 (95% confidence interval [CI]: 0.75 to 0.78) in the derivation cohort and 0.71 (95% CI: 0.69 to 0.74) in the validation cohort. Patients who scored ≤7 points had a low negative likelihood ratio (risk CAD was 1% in patients with ≤7 points and 16.7% in those with ≥18 points. We propose a scoring system, based on clinical variables, that can be used to identify patients at high and low pre-test probability of having high-risk CAD. Identification of these populations may detect those who may benefit from a trial of medical therapy and those who may benefit most from an invasive strategy.

    Few data are available on whether adjusting the dose of posaconazole syrup is effective in patients receiving anti-cancer chemotherapy. The aim of this prospective study was to analyse the impact of increasing the frequency of posaconazole administration on optimal plasma concentrations in adult patients with haematological malignancy. A total of 133 adult patients receiving chemotherapy for acute myeloid leukaemia or myelodysplastic syndrome who received posaconazole syrup 200 mg three times daily for fungal prophylaxis were enrolled in this study. Drug trough levels were measured by liquid chromatography-tandem mass spectrometry. In 20.2% of patients (23/114) the steady-state concentration of posaconazole was suboptimal (posaconazole administration was increased to 200 mg four times daily. On Day 15, the median posaconazole concentration was significantly increased from 368 ng/mL [interquartile range (IQR), 247-403 ng/mL] to 548 ng/mL (IQR, 424-887 ng/mL) (P = 0.0003). The median increase in posaconazole concentration was 251 ng/mL (IQR, 93-517 ng/mL). Among the patients with initially suboptimal levels, 79% achieved the optimal level unless the steady-state level was posaconazole syrup is effective for achieving optimal levels in patients with haematological malignancy undergoing chemotherapy.

    For patients with haematological malignancies, information on disease, prognosis, treatment and impact on quality of life is of the utmost importance. To gain insight into the perceived need for information in relation to sociodemographic and clinical parameters, comorbidity, quality of life (QoL) and information satisfaction, we compiled a questionnaire based on existing validated questionnaires. A total of 458 patients diagnosed with a haematological malignancy participated. The perceived need for information was moderate to high (40-70%). Multivariate regression analyses showed that a higher need for information was related to younger age, worse QoL, being member of a patient society and moderate comorbidity. The need for disease and treatment-related information was higher than the need for psychosocial information. A higher need for disease and treatment-related information was associated to being diagnosed with multiple myeloma. A higher need for psychosocial information was related to a lower educational level. The information provision could be improved according to 41% of the patients. Higher satisfaction with provided information was associated with better QoL. Most patients (62%) reported that they wanted to be fully informed about their illness and actively involved in treatment decision-making. The results contribute to improving patient-tailored information provision and shared decision-making in clinical practice. Copyright © 2014 John Wiley & Sons, Ltd.

    Hypertrophic cardiomyopathy(HCM) is the most common cause of sudden cardiac death(SCD) in the young, particularly among athletes. Identifying high risk individuals is very important for SCD prevention. The purpose of this review is to stress that noninvasive diagnostic testing is important for risk assessment. Extreme left ventricular hypertrophy and documented ventricular tachycardia and fibrillation increase the risk of SCD. Fragmented QRS and T wave inversion in multiple leads are more common in high risk patients. Cardiac magnetic resonance imaging provides complete visualization of the left ventricular chamber, allowing precise localization of the distribution of hypertrophy and measurement of wall thickness and cardiac mass. Moreover, with late gadolinium enhancement, patchy myocardial fibrosis within the area of hypertrophy can be detected, which is also helpful in risk stratification. Genetic testing is encouraged in all cases, especially in those with a family history of HCM and SCD.

    Full Text Available MRSA is an important hospital pathogen, the incidence of which is increasing every year especially in high risk groups. The present study was performed in high risk patients admitted in burns and orthopaedic units of LN hospital to study the infection rate of MRSA from these units. The proportion of MRSA amongst S. aureus isolates was found to be 51.6% and these isolates were multidrug resistant. Phage typing of these isolates gave a typeability of 41.8% using the MRSA set of phages. Biotyping of these isolates could divide them into four groups. The study shows a high incidence of MRSA from burns and orthopaedic units with a high level of antibiotic resistance amongst these isolates.

    The aim of this study was to predict the probability of central venous catheter-related bloodstream infections (CRBSIs) in patients with haematologic malignancies using a modified version of the Infection Probability Score (mIPS). In order to perform a prospective, mono-centric surveillance of complications in clinical routine due to short-term central venous catheters (CVCs) in consecutive patients receiving chemotherapy from March 2013 to September 2014, IPS was calculated at CVC insertion and removal (mIPSin and mIPSex, respectively). We used the 2012 Infectious Diseases Working Party of the German Society of Haematology and Medical Oncology (AGIHO/DGHO) criteria to define CRBSI. In total, 143 patients (mean 59.5 years, 61.4 % male) with 267 triple-lumen CVCs (4044 CVC days; mean 15.1 days, range 1-60 days) were analysed. CVCs were inserted for therapy of acute leukaemia (53.2 %), multiple myeloma (24.3 %) or lymphoma (11.2 %), and 93.6 % were inserted in the jugular vein. A total of 66 CRBSI cases (24.7 %) were documented (12 definite/13 probable/41 possible). The incidence was 16.3/1000 CVC days (2.9/3.1/10.1 per 1000 CVC days for definite/probable/possible CRBSI, respectively). In CRBSI cases, the mIPSex was higher as compared to cases without CRBSI (13.1 vs. 7.1; p < 0.001). The best mIPSex cutoff for CRBSI prediction was 8 points (area under the curve (AUC) = 0.77; sensitivity = 84.9 %, specificity = 60.7 %, negative predictive value = 92.4 %). For patients with an mIPSex ≥8, the risk for a CRBSI was high (odds ratio [OR] = 5.9; p < 0.001) and even increased if, additionally, CVC had been in use for about 10 days (OR = 9.8; p < 0.001). In case other causes of infection are excluded, a mIPSex ≥8 and duration of CVC use of about 10 days predict a very high risk of CRBSI. Patients with a mIPSex <8 have a low risk of CRBSI of 8 %.

    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.

    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 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

    2012-02-01

    BACKGROUND: Overall survival in paediatric cancer has improved significantly over the past 20 years. Treatment strategies have been intensified, and supportive care has made substantial advances. Historically, paediatric oncology patients admitted to an intensive care unit (ICU) have had extremely poor outcomes. METHODS: We conducted a retrospective cohort study over a 3-year period in a single centre to evaluate the outcomes for this particularly vulnerable group of patients admitted to a paediatric ICU. RESULTS: Fifty-five patients were admitted a total of 66 times to the ICU during the study period. The mortality rate of this group was 23% compared with an overall ICU mortality rate of 5%. 11\\/15 patients who died had an underlying haematological malignancy. Twenty-eight percent of children with organism-identified sepsis died. CONCLUSIONS: While mortality rates for paediatric oncology patients admitted to a ICU have improved, they are still substantial. Those with a haematological malignancy or admitted with sepsis are most at risk.

    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

    In view of the poor outcomes associated with mucormycosis in patients with haematologic malignancies (HM) and haematopoietic cell transplant recipients, antifungal combinations are frequently used, yet the value of such strategy remains unclear. We reviewed the records of HM patients treated for mucormycosis from 1994 to 2014. The primary outcome was 6-week mortality after treatment initiation. Of the 106 patients identified, 44% received monotherapy and 56% received combination treatment as initial therapy. Six-week mortality was associated with disseminated mucormycosis (p 0.018), active malignancy (p mucormycosis (p mucormycosis was associated with better outcome (OR, 0.06; 95% CI, 0.01-0.6; p 0.019). Initial combination treatment had no impact on mortality, even after propensity score adjustment (OR, 0.8; 95% CI, 0.3-2.4; p 0.69). A weighted mortality risk score was then calculated for each patient based on the factors independently associated with mortality and baseline APACHE II score. In the low-risk group (n = 49), 13% of monotherapy versus 15% of combination therapy patients died within 6 weeks (p >0.99). In the high-risk group (n = 57), 71% of monotherapy versus 61% of combination therapy patients died within 6 weeks (p 0.42). With the current status of mucormycosis diagnosis, there was no difference in mortality in HM patients, whether they received monotherapy or combination treatment as initial therapy. Earlier diagnosis and immune reconstitution are unmet needs to affect outcomes.

    Full Text Available Objective: To compare the frequency of fungal infection and mortality rates in patients with hematological malignity and receiving either flucanazole (FLU or posaconazole (POS prophylaxis. Methods: This retrospective, observational study investigated fungal prophylaxis in patients with a high risk of invasive fungal infections (IFIs and diagnosed with hematological malignity at our hospital hematology clinic between 01.01.2011 and 01.01.2013. FLU (n=70 was the prophylactic regimen between 2011 and 2012 which was replaced by POS (n=35 in the following period. The incidence and mortality rates of IFIs developing in the two periods were compared. Results: The incidence of IFI in patients administered FLU prophylaxis was 22/70 (31%, compared to 13/35 (37% in the patients receiving POS. Incidence of invasive pulmonary aspergillosis (IPA in the FLU group was 21/70 (31%, compared to 9/35 (26% in the POS group. The mortality rate in the group receiving FLU prophylaxis was 17 (24%, compared to 4 (11% in the POS group. The difference was attributed to causes other than fungal infection. Results of subgroup analysis performed for AML were similar to the general findings in terms of both incidences of fungal infection and of mortality levels. In multivariate analysis, mean duration of neutropenia was correlated with prophylaxis failure. Conclusion:We conclude that both agents can be successfully used in fungal infection prophylaxis for patients at high risk for IFI. J Microbiol Infect Dis 2014;4(1: 1-6

    Background The incidence of brain metastases in patients with breast cancer is approximately 10%-16%,and survival after diagnosis of brain metastases is usually short.This study was designed to evaluate the risk factors associated with brain metastases in advanced breast cancer patients,with a view to help predict patient groups with high risk of brain metastases.Methods In total,295 patients with advanced breast cancer were evaluated.All patients were pathologically confirmed and metastatic lesions were confirmed pathologically or by imaging.All patients were examined at least once every 6 months with head CT or MRI.Patients showing symptoms underwent immediate inspection,and brain metastatic lesions were confirmed by head CT and/or MRI.Results At a median follow-up of 12 months from the occurrence of metastases,brain metastases had occurred in 49 patients (16.6%).In our univariate analysis,variables significantly related to increased risk of brain metastases were hormone receptor-negative tumors,epidermal growth factor receptor 2 (HER2)-positive tumors,and multiple distant metastases.Patients with dominant tumor sites in soft tissue,or defined as Luminal A subtype,tended to have a lower risk of brain metastases than patients with visceral metastases,Luminal B subtype,triple-negative subtype or HER2-enriched subtype tumors.Conclusions Our results strongly suggest that factors such as Luminal B,triple-negative,and HER2-enriched subtypes are high risk factors for brain metastases.These data,therefore,provide pivotal clinical evidence towards a comprehensive understanding of the risk factors of brain metastases in advanced breast cancer patients.

    In the Apixaban for Prevention of Acute Ischemic Events (APPRAISE-2) trial, the use of apixaban, when compared with placebo, in high-risk patients with a recent acute coronary syndrome (ACS) resulted in a significant increase in bleeding without a reduction in ischaemic events. The aim of this analysis was to provide further description of these bleeding events and to determine the baseline characteristics associated with bleeding in high-risk post-ACS patients. APPRAISE-2 was a multinational clinical trial including 7392 high-risk patients with a recent ACS randomised to apixaban (5 mg twice daily) or placebo. Bleeding including Thrombolysis in Myocardial Infarction (TIMI) major or minor bleeding, International Society on Thrombosis and Haemostasis (ISTH) major or clinically relevant non-major (CRNM) bleeding, and any bleeding were analysed using an on-treatment analysis. Kaplan-Meier curves were plotted to describe the timing of bleeding, and a Cox proportional hazards model was used to identify predictors of ISTH major or CRNM bleeding and any bleeding. Median follow-up was 241 days. The proportion of patients who experienced TIMI major or minor, ISTH major or CRNM, and any bleeding was 1.5%, 2.2% and 13.3%, respectively. The incidence of bleeding was highest in the immediate post-ACS period (0.11 in the first 30 days vs 0.03 after 30 days events per 1 patient-year); however, >60% of major bleeding events occurred >30 days after the end of the index hospitalisation. Gastrointestinal bleeding was the most common cause of major bleeding, accounting for 45.9% of TIMI major or minor and 39.5% of ISTH major or CRNM bleeding events. Independent predictors of ISTH major or CRNM bleeding events included older age, renal dysfunction, dual oral antiplatelet therapy, smoking history, increased white cell count and coronary revascularisation. When compared with placebo, the use of apixaban is associated with an important short-term and long-term risk of bleeding

    AIM: To identify patients with a high-risk of having a synchronous cancer among gastric cancer patients.METHODS: We retrospectively analyzed the prospective gastric cancer database at the National Cancer Center,Korea from December 2000 to December 2004. The clinicopathological characteristics of patients with synchronous cancers and those of patients without synchronous cancers were compared. Multivariate analysis was performed to identify the risk factors for the presence of a synchronous cancer in gastric cancer patients.RESULTS: 111 of 3291 gastric cancer patients (3.4%)registered in the database had a synchronous cancer.Among these 111 patients, 109 had a single synchronous cancer and 2 patients had two synchronous cancers. The most common form of synchronous cancer was colorectal cancer (42 patients, 37.2%) followed by lung cancer (21 patients, 18.6%). Multivariate analyses revealed that elderly patients with differentiated early gastric cancer have a higher probability of a synchronous cancer.CONCLUSION: Synchronous cancers in gastric cancer patients are not infrequent. The physicians should try to find synchronous cancers in gastric cancer patients,especially in the elderly with a differentiated early gastric cancer.

    Background It is still unclear whether pulmonary function tests (PFTs) are sufficient for predicting perioperative risk,and whether all patients or only a subset of them need a cardiopulmonary exercise test (CPET) for further assessment.Thus, this study was designed to evaluate the CPET and compare the results of CPET and conventional PFTs to identify which parameters are more reliable and valuable in predicting perioperative risks for high risk patients with lung cancer.Methods From January 2005 to August 2008, 297 consecutive lung cancer patients underwent conventional PFTs (spirometry + single-breath carbon monoxide diffusing capacity of the lungs (DLCOsb) for diffusion capacity) and CPET preoperatively. The correlation of postoperative cardiopulmonary complications with the parameters of PFT and CPET was retrospectively analyzed using the chi-square test, independent sample t test and binary Logistic regression analysis.Results Of the 297 patients, 78 did not receive operation due to advanced disease stage or poor cardiopulmonary function. The remaining 219 underwent different modes of operations. Twenty-one cases were excluded from this study due to exploration alone (15 cases) and operation-related complications (6 cases). Thus, 198 cases were eligible for evaluation. Fifty of the 198 patients (25.2%) had postoperative cardiopulmonary complications. Three patients (1.5%)died of complications within 30 postoperative days. The patients were stratified into groups based on VO2max/pred respectively. The rate of postoperative cardiopulmonary complications was significantly higher in the group with cardiopulmonary complications were significantly correlated with age, comorbidities, and poor PFT and CPET results.used to stratify the patients' cardiopulmonary function status and to predict the risk of postoperative cardiopulmonary predicting perioperative risk. If available, cardiopulmonary exercise testing is strongly suggested for high-risk lung cancer patients in

    Background Large-scale clinical trials have shown that routine monitoring of the platelet function in patients after percutanous coronary intervention (PCI) is not necessary.However,it is still unclear whether patients received high-risk PCI would benefit from a therapy which is guided by a selective platelet function monitoring.This explanatory study sought to assess the benefit of a therapy guided by platelet function monitoring for these patients.Methods Acute coronary syndrome (ACS) patients (n=384) who received high-risk,complex PCI were randomized into two groups.PCI in the two types of lesions described below was defined as high-risk,complex PCI:lesions that could result in severe clinical outcomes if stent thrombosis occurred or lesions at high risk for stent thrombosis.The patients in the conventionally treated group received standard dual antiplatelet therapy.The patients in the platelet function monitoring guided group received an antiplated therapy guided by a modified thromboelastography (TEG) platelet mapping:If inhibition of platelet aggregation (IPA) induced by arachidonic acid (AA) was less than 50% the aspirin dosage was raised to 200 mg/d; if IPA induced by adenosine diphosphate (ADP) was less than 30% the clopidogrel dosage was raised to 150 mg/d,for three months.The primary efficacy endpoint was a composite of myocardial infarction,emergency target vessel revascularization (eTVR),stent thrombosis,and death in six months.Results This study included 384 patients; 191 and 193 in the conventionally treated group and platelet function monitoring guided group,respectively.No significant differences were observed in the baseline clinical characteristics and interventional data between the two groups.In the platelet function monitoring guided group,the mean IPA induced by AA and ADP were (69.2±24.5)% (range,4.8% to 100.0%) and (51.4±29.8)% (range,0.2% to 100.0%),respectively.The AAinduced IPA of forty-three (22.2%) patients was less

    Lung cancer is among the most common cancers worldwide and is the leading cause of cancer death in both men and women. For patients with early stage (American Joint Committee on Cancer T1-2, N0) non-small-cell lung cancer, the current standard of care is lobectomy with systematic lymph node evaluation. Unfortunately, patients with lung cancer often have medical comorbities, which may preclude the option of surgical resection. In such cases, a number of minimally invasive to noninvasive treatment options have gained popularity in the treatment of these high-risk patients. These modalities provide significant advantages, including patient convenience, treatment in an outpatient setting, and acceptable toxicities, including reduced impact on lung function and a modest risk of postprocedure chest wall pain. We provide a comprehensive review of the literature, including reported outcomes, complications, and limitations of sublobar resection with or without intraoperative brachytherapy, radiofrequency ablation, microwave ablation, percutaneous cryoablation, photodynamic therapy, and stereotactic body radiotherapy.

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

    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.

    Full Text Available Objective: to study the hemodynamic effects of sevoflurane during the induction of anesthesia in elderly patients at high risk for cardiac events. Subjects and methods. This study enrolled 32 patients who had a left ventricular ejection fraction of <30% during preoperative examination. According to the presumptive type of anesthesia, the patients were randomized to one of the study groups: In the sevoflurane group receiving infusion of fentanyl (1 ig^kg”‘^hr”‘, anesthesia was induced by sevoflurane at the maximum concentration of 8 vol% at first inspiration, without the respiratory circuit being prefilled. After loss of consciousness, further saturation was carried out using Fianesth, 5 vol%. Combination anesthesia (CA was that which was induced by successive administration of dormicum, ketamine, propo-fol, and fentanyl. The trachea was intubated during total myoplegia under the control of TOF (TOF-Watch, Organon, the Netherlands. Results. In all the patients under CA, its induction was made during infusion of dopamine (5 lg^kg”‘^min”‘, the dose of which had to be increased up to 10 ig • kg-1 • min-1 in 6 (75% patients. Nevertheless, there were decreases in mean blood pressure (BPmean to 46±6 mm Hg and in cardiac index (CI to 1.5±0.3 fig • kg-1 • min-1 (by 32% of the outcome value. In the sevoflurane inhalation induction group, only 3 (12.5% patients needed dopamine. Its dose producing a cardiotonic effect was near-minimal; its average maintenance infusion rate was 5.3±0.3 ig^kg”‘^min”‘. The reduction in CI was statistically insignificant; despite a 9% decrease in BPmean, this indicator in the sevoflurane group remained within acceptable ranges. Conclusion. The use of a sevoflurane-based inhalation induction technique permits higher hemodynamic stability in patients at high risk for cardiac events. Key words: inhalation induction, sevoflurane, ketamine, elderly patients.

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

    Reuter, Daniel A

    2012-01-31

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

    To evaluate the utility and safety of remifentanil for hemodynamic control during cesarean section in high-risk patients ineligible for spinal anesthesia. One minute before induction we injected a bolus of 1 microg x kg(-1) of remifentanil, followed by propofol (2.5 mg x kg(-1)), succinylcholine (1 mg x kg(-1)), cisatracurium, sevoflurane in oxygen and nitrous oxide, and fentanyl (5 microg x kg(-1)) after clamping the umbilical cord. We recorded maternal hemodynamic variables, pulse oximetry, capnography, bispectral index, and presence of muscular rigidity. In the neonate we assessed fetal wellbeing, weight, and requirement for naloxone. Hemodynamic stability was defined as no more than 15% variation in arterial pressure with respect to baseline. Twelve patients undergoing surgery because of placenta abruptio, subarachnoid hemorrhage, HELLP syndrome, or preeclampsia were enrolled. Hemodynamic variables were consistently stable during surgery in all patients. No cases of neonatal rigidity were noted and there was no need for naloxone. The mean Apgar score was 6.42 (1.5) at 1 minute and 8.42 (0.9) at 5 minutes. Bolus injection of 1 microg x kg(-1) of remifentanil may be useful for maintaining maternal hemodynamic stability in high-risk obstetric cases. Given the risk of neonatal depression, this resource should be used selectively and the means for neonatal resuscitation should be available.

    Objective: To determine the patterns of distribution of HCV genotypes among high risk population in north of Iran. Methods: A cross-sectional study was conducted on 135 HCV RNA-positive high risk individuals including thalassemia, hemophilia, patients under hemodialysis and intravenous drug addicts. HCV genotypes were determined based on amplification with type-specific primers methods. Results: Among the 187 anti-HCV positive samples, only 135 (72.2%) gave HCV-RNA positvity. Over all, the most identified HCV type was genotype 3a (51.1%) followed by 1a (27.4%), 1b (8.2%). Sixteen (11.9%) out of 135 HCV RNA-positive participants have infected with more than one genotype or subtypes as follow; 1a/1b in 11 (8.2%), 2/3a in 3 (2.2%), and 1a/1b/3a in 2 (1.5%). Stratification of participants revealed that HCV subtype 3a was more prominent in thalassemia, hemophilia and HD patients but 1a and 1b were frequent in intravenous drug addicts. Conclusions: This study is the first report on HCV genotypes among Iranian subjects with different exposure categories resided in Mazandaran, where genotype 3a was found to be the most frequent genotype in thalassemia, hemophilia, and hemodialysis patients but not in IDAs. Since the addiction age is decreasing in Iran and a lot of addicts are IDAs, it might change the subtype pattern of HCV in general population.

    information provided about the average age and sex of the study population. We found a high risk for attrition bias and unclear risk for reporting bias, performance and detection bias because of missing data due to abstract publication only, thus we judged the overall risk of bias as high. According to the GRADE criteria, we judged the overall quality of the body of evidence for all predefined outcomes as 'very low', due to the extent of missing data on the study population, and the small sample size.As the abstract publication did not provide numbers and results except P values, we are not able to give more details.Meditation practice might be beneficial for the quality of life of haematologically-diseased patients, with higher scores for participants in the mediation arms compared to the participants in the usual care control group (low quality of evidence). Levels of depression decreased for those practising meditation in both the spiritually-framed meditation group and the secularly-focused meditation group in comparison to the usual care control group, whose levels of depression remained constant (low quality of evidence). The influence of meditation practice on overall survival, fatigue, anxiety, quality of sleep and adverse events remained unclear, as these outcomes were not evaluated in the included trial. To estimate the effects of meditation practice for patients suffering from haematological malignancies, more high quality randomised controlled trials are needed. At present there is not enough information available on the effects of meditation in haematologically-diseased patients to draw any conclusion.

To analyze the recurrence of cholecystitis after catheter withdrawal in patients considered unsuitable candidates for delayed surgery, with the aim of identifying factors that predict recurrence. We reviewed 40 patients who underwent percutaneous cholecystostomy in a two-year period. We analyzed survival during hospitalization in relation with fever, abdominal pain, leukocytosis, and C-reactive protein before and after the procedure. We analyzed the recurrence of cholecystitis after catheter withdrawal in patients considered unsuitable candidates for delayed surgery, as well as the influence of obstruction seen on cholangiography, age, sex, and comorbidities on the recurrence rate. During the hospital stay, 4 (10%) patients died of septic shock. Cholecystostomy improved fever, leukocytosis, and abdominal pain within five days of the procedure, but these improvements did not have a statistically significant effect on survival and were not therefore considered useful prognostic factors. Among the 15 patients considered unsuitable candidates for delayed surgery, 6 (40%) had recurrences of cholecystitis during a mean follow-up period of 6.7 months after catheter withdrawal. We found no association between recurrence and any of the parameters analyzed. Outcomes in our series of patients with high risk for surgery who underwent cholecystostomy for urgent treatment of acute cholecystitis were similar to those reported in other series. Withdrawing the catheter in patients considered unsuitable candidates for delayed surgery is not recommended due to the high risk of recurrence of cholecystitis in comparison with other series.

    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.

    Full Text Available 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.

    Survival for patients with idiopathic pulmonary fibrosis (IPF) and high lung allocation score (LAS) values may be significantly reduced in comparison to those with lower LAS values. To evaluate outcomes for high-risk IPF patients as defined by LAS values ≥46 (N=42) versus recipients with LAS values lung transplants at our institution between 1999 and 2013. The mean LAS was significantly higher (59.5, interquartile range 43.9-75.9 vs. 39.3, interquartile range 37.7-44.3; plung transplantation in patients with IPF and high LAS values is associated with increased risk of early post-transplant complications, long-term post-transplant survival for our high-LAS cohort was equivalent to that for the lower LAS recipients.

    A significant number of surgical patients are at risk of intra- or post-operative complications or both, which are associated with increased lengths of stay, costs, and mortality. Reducing these risks is important for the individual patient but also for health-care planners and managers. Insufficient tissue perfusion and cellular oxygenation due to hypovolemia, heart dysfunction or both is one of the leading causes of perioperative complications. Adequate perioperative management guided by effective and timely hemodynamic monitoring can help reduce the risk of complications and thus potentially improve outcomes. In this review, we describe the various available hemodynamic monitoring systems and how they can best be used to guide cardiovascular and fluid management in the perioperative period in high-risk surgical patients.

    The aim of this study was to determine the effect of art therapy on post-traumatic growth in patients with haematological malignancies in a non-randomised trial (n = 36, intervention group; n = 129, control group). Art therapy was administered over a period of 22 weeks in small groups. Post-traumatic growth was measured with the Stress-Related Growth Scale. After controlling for the effect of potential confounders, no difference in post-traumatic growth was observed between the intervention and control groups after 22 weeks. There was no evidence for an effect of weekly group sessions with art therapy on post-traumatic growth in patients with haematological malignancies.

    Full Text Available Abstract Background There is still much debate about the best adjuvant therapy after surgery for endometrial cancer (EC and there are no current guidelines. Radiotherapy (RT alone does not seem to improve overall survival. We investigated whether concomitant Paclitaxel (P and RT gave better clinical results. Methods Twenty-three patients with high-risk EC (stage IIB, IIIA, IIIC or IC G3 without lymphadenectomy or with aneuploid tumor underwent primary surgery and were then referred for adjuvant therapy. P was given at a dose of 60 mg/m2 once weekly for five weeks during RT, which consisted of a total radiation dose of 50.4 Gy. Three further weekly cycles of P at a dose of 80 mg/m2 were given at the end of RT. Overall survival and disease-free survival were calculated from the time of surgery. Patterns of failure were recorded by the sites of failure. Results A total of 157 cycles of P were administered both during radiotherapy and consolidation chemotherapy. Relapses occurred in five patients (21.7%. Median time to recurrence was 18.6 months (range 3–28. Survival rate for all the patients was 78.2%. Overall survival for the patients who completed chemo-radiation was of 81%. In this group median time to recurrence was 19.2 months (range 3–28. All recurrences were outside the radiation field. Mortality rate was 14.2%. Conclusion This small series demonstrates pelvic radiotherapy in combination with weakly P followed by three consolidation chemotherapy cycles as an effective combined approach in high risk endometrial carcinoma patients.

    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

    Percutaneous left atrial appendage (LAA) occlusion has been developed as a viable option for stroke and thromboembolism prevention in patients with non-valvular atrial fibrillation (NVAF) and at high risk for cerebral cardioembolic events. Data on device implantation and long-term follow-up from large cohorts are limited. 110 consecutive patients with NVAF and contraindications to oral anticoagulants (OACs) underwent LAA occlusion procedures and achieved a longer than 1 year follow-up. All patients were enrolled in a prospective registry. Procedures were performed using the Amplatzer Cardiac Plug or Amulet guided by fluoroscopy and intracardiac echocardiography. Mean age of the population was 77±6 years old; 68 were men. Atrial fibrillation was paroxysmal in 20%, persistent in 15.5% and permanent in 64.5% of cases, respectively. Mean CHA2DS2-VASc and HAS-BLED scores were 4.3±1.3 and 3.4±1, respectively. Technical success (successful deployment and implantation of device) was achieved in 100% of procedures. Procedural success (technical success without major procedure-related complications) was achieved in 96.4%, with a 3.6% rate of major procedural complications (three cases of pericardial tamponade requiring drainage and one case of major bleeding). Mean follow-up was 30±12 months (264 patient-years). Annual rates for ischaemic stroke and for other thromboembolic events were respectively 2.2% and 0%, and annual rate for major bleeding was 1.1%. Our data suggest LAA occlusion in high-risk patients with NVAF not suitable for OACs is feasible and associated with low complication rates as well as low rates of stroke and major bleeding at long-term follow-up.

    Background The results from the ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial (ONTARGET) indicated that the angiotensin-receptor blocker telmisartan was not inferior to the angiotensin-converting-enzyme inhibitor ramipril in reducing the composite endpoint of cardiovascular death, myocardial infarction, stroke or hospitalization for congestive heart failure in high-risk patients, and telmisartan was associated with slightly superior tolerability. The combination of the two drugs was associated with more adverse events without an increase in benefit. This study aimed to analyze the data from ONTARGET obtained from a subgroup of patients enrolled in China and to evaluate the demographic and baseline characteristics, the compliance, efficacy, and safety of the different treatment strategies in randomized patients in China.Methods A total of 1159 high-risk patients were randomized into three treatment groups: with 390 assigned to receive 80 mg of telmisartan, 385 assigned to receive 10 mg of ramipril and 384 assigned to receive both study medications. The median follow-up period was 4.3 years.Results The mean age of Chinese patients was 65.6 years, 73.6% of patients were male. The proportion of patients with stroke/transient ischemic attacks at baseline in China was two times more than the entire study population (47.7% vs. 20.9%). In Chinese patients the proportion of permanent discontinuation of study medication due to cough was 0.5% in the telmisartan group, which was much less than that in the combination or the ramipril group. There were no significant differences in the incidence of primary outcome among three treatment groups of Chinese patients. More strokes occurred in Chinese patients than in the entire study population (8.5% vs. 4.5%). Greater systolic blood pressure reduction (-9.8 mmHg), and more renal function failure were noted in the combination treatment group than in the ramipril or telmisartan group (2.6% vs. 1

    Full Text Available Abstract Background Statins are widely prescribed to patients with atherosclerosis. A retrospective database analysis was used to examine the role of preoperative statin use in hospital mortality, for patients undergoing isolated coronary artery bypass grafting (CABG. Methods The study population comprised 2377 patients who had isolated CABG at Allegheny General Hospital between 2000 and 2004. Mean age of the patients was 65 ± 11 years (range 27 to 92 years. 1594 (67% were male, 5% had previous open heart procedures, and 4% had emergency surgery. 1004 patients (42% were being treated with a statin at the time of admission. Univariate, bivariate (Chi2, Fisher's Exact and Student's t-tests and multivariate (stepwise linear regression analyses were used to evaluate the association of statin use with mortality following CABG. Results Annual prevalence of preoperative statin use was similar over the study period and averaged 40%. Preoperative clinical risk assessment demonstrated a 2% risk of mortality in both the statin and non-statin groups. Operative mortality was 2.4% for all patients, 1.7% for statin users and 2.8% for non-statin users (p Conclusions Between 2000 and 2004 less than 50% of patients at this institution were receiving statins before admission for isolated CABG. A retrospective analysis of this cohort provides evidence that preoperative statin use is associated with lower operative mortality in high-risk patients.

    Tosedostat, an oral aminopeptidase inhibitor, has synergy with cytarabine and hypomethylating agents. We performed a Phase II trial to determine rates of complete remission (CR) and survival using tosedostat with cytarabine or decitabine in older patients with untreated acute myeloid leukaemia (AML) or high-risk myelodysplastic syndrome (MDS). Thirty-four patients ≥60 years old (median age 70 years; range, 60-83) were randomized to receive tosedostat (120 mg on days 1-21 or 180 mg continuously) with 5 d of either cytarabine (1 g/m2 /d) or decitabine (20 mg/m2 /d) every 35 d. Twenty-nine patients (85%) had AML, including 15 (44%) with secondary AML/MDS, and 5 (15%) had MDS-refractory anaemia with excess blasts type 2. The CR/CR with incomplete count recovery (CRi) rate was 53% [9 in each arm; 14 CR (41%) and 4 CRi (12%)], attained in 6 of 14 patients with adverse cytogenetics and 4 of 7 with FLT3-internal tandem duplication mutations. Median follow-up was 11.2 months (range, 0.5-22.3), and median survival was 11.5 months (95% confidence interval, 5.2-16.7). Twenty-three patients (67.6%) were treated as outpatients and 10 of these patients required hospitalization for febrile neutropenia. No Grade 3-4 non-haematological toxicities required withdrawal from study. Tosedostat with cytarabine or decitabine is tolerated in older patients with untreated AML/MDS, results in a CR/CRi rate of >50%, and warrants further study in larger trials.

    From January 1, 2003, through December 31, 2010, drug overdose deaths in Tennessee increased from 422 to 1059 per year. More of these deaths involved prescription opioids than heroin and cocaine combined. To assess the contribution of certain opioid-prescribing patterns to the risk of overdose death. We performed a matched case-control study that analyzed opioid prescription data from the Tennessee Controlled Substances Monitoring Program (TNCSMP) from January 1, 2007, through December 31, 2011, to identify risk factors associated with opioid-related overdose deaths from January 1, 2009, through December 31, 2010. Case patients were ascertained from death certificate data. Age- and sex-matched controls were randomly selected from among live patients in the TNCSMP. We defined a high-risk number of prescribers or pharmacies as 4 or more per year and high-risk dosage as a daily mean of more than 100 morphine milligram equivalents (MMEs) per year. The main outcome was opioid-related overdose death. From January 1, 2007, through December 31, 2011, one-third of the population of Tennessee filled an opioid prescription each year, and opioid prescription rates increased from 108.3 to 142.5 per 100 population per year. Among all patients in Tennessee prescribed opioids during 2011, 7.6% used more than 4 prescribers, 2.5% used more than 4 pharmacies, and 2.8% had a mean daily dosage greater than 100 MMEs. Increased risk of opioid-related overdose death was associated with 4 or more prescribers (adjusted odds ratio [aOR], 6.5; 95% CI, 5.1-8.5), 4 or more pharmacies (aOR, 6.0; 95% CI, 4.4-8.3), and more than 100 MMEs (aOR, 11.2; 95% CI, 8.3-15.1). Persons with 1 or more risk factor accounted for 55% of all overdose deaths. High-risk use of prescription opioids is frequent and increasing in Tennessee and is associated with increased overdose mortality. Use of prescription drug–monitoring program data to direct risk-reduction measures to the types of patients overrepresented

    Patient characteristics and procedural outcomes from nontransfemoral (non-TF) transcatheter aortic valve replacement (TAVR) in high-risk or inoperable patients with aortic stenosis have been incompletely reported. The purpose of this study was to compare outcomes with non-TF TAVR access techniques including transapical (TA), transaortic (TAo), and transcarotid (TC) TAVR with a balloon-expandable valve. A retrospective review was performed of all patients undergoing TA, TAo, and TC TAVR from 2007 to 2013 at Emory University. Preoperative risk factors and postoperative outcomes were evaluated using Valve Academic Research Consortium-2 definitions. Of 469 patients undergoing TAVR during that period at our institution, 139 underwent TA TAVR, 35 had Tao TAVR, and 11 had TC TAVR. Patients undergoing TC TAVR were younger than those undergoing TA TAVR and TAo TAVR (mean ages: TC, 68.9 ± 23.6 years; TA, 81.3 ± 7.7 years; Tao, 83.8 ± 8.3 years; p = 0.017). Most patients undergoing TAo TAVR were women (82.9%), whereas patients undergoing TA TAVR were more likely to be men (62.6%). Slightly more than half of patients undergoing TA TAVR (54.7%) and TC (54.6%) TAVR had undergone previous coronary artery bypass grafting (CABG), whereas no patients underwent TAo TAVR (0%). There was no preoperative difference in ejection fraction, New York Heart Association classification, significant chronic obstructive pulmonary disease, and The Society of Thoracic Surgeons predicted risk of mortality between TA TAVR, Tao TAVR, and TC TAVR, respectively. Average postoperative length of stay was 9 to 11 days and was similar among groups (p = 0.22). There were 13 (9.4%) TA TAVR operative deaths and 4 (11.4%) operative deaths in the TAo TAVR group. There were no deaths in the TC TAVR group. In high-risk and inoperable patients who are not candidates for TF TAVR, careful selection of alternative access options can lead to excellent and comparable postoperative outcomes.

    The optimal treatment strategy for patients with clinical stage I (CS-1) seminoma is controversial. The objective of the current study was to evaluate the outcomes for patients considered to be at high risk of disease recurrence with a tumor size ≥6 cm. Patients were treated with either adjuvant radiotherapy (RT) or followed with surveillance. From the Danish Testicular Cancer database, the authors identified 473 patients with CS-1 seminoma with a tumor size ≥6 cm. Of these, 254 patients underwent adjuvant RT and 219 were followed with surveillance. Cumulative incidence function was applied to estimate the risk of disease recurrence, risk of second malignant neoplasm, and risk of receiving >1 line of treatment. Survival of the 2 groups was compared with the log-rank test and Cox model including age at diagnosis. No significant differences were found with regard to overall survival or risk of a second malignant neoplasm. Patients undergoing adjuvant RT received more treatments per patient than patients followed with surveillance, but there was no significant difference noted with regard to the risk of receiving >1 line of treatment. The 10-year cumulative incidence of disease recurrence was 32% versus 2.8%, respectively, for patients followed with surveillance and adjuvant RT. In patients followed with surveillance who developed disease recurrence, there was a high incidence of second recurrences after RT. The 10-year overall survival was found to be similar irrespective of primary treatment. Adjuvant RT was found to effectively reduce the rate of disease recurrence but resulted in the overtreatment of approximately two-thirds of the patients. The high incidence of second disease recurrences after RT in the patients followed with surveillance needs be addressed in future studies.

    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.

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

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

    Full Text Available Abstract Background To determine if recommended treatment targets, as specified in clinical practice guidelines for the management of cardiovascular disease, reduces the risk of renal complications in high risk patient populations. Methods This was a cohort study. Participants in Utrecht, The Netherlands either at risk of, or had cardiovascular disease were recruited. Cardiovascular treatment targets were achievement of control in systolic and diastolic blood pressure, total and low-density cholesterol, and treatment of albuminuria. Outcome measures were time to development of end stage renal failure or symptomatic renal atherosclerotic disease requiring intervention. Results The cohort consisted of 7,208 participants; 1,759 diabetics and 4,859 with clinically manifest vascular disease. The median age was 57 years and 67% were male. Overall, 29% of the cohort achieved the treatment target for systolic blood pressure, 39% for diastolic blood pressure, 28% for total cholesterol, 31% for LDL cholesterol and 78% for albuminuria. The incidence rate for end stage renal failure and renal atherosclerotic disease reduced linearly with each additional treatment target achieved (p value less than 0.001. Achievement of any two treatment targets reduced the risk of renal complications, hazard ratio 0.46 (95% CI 0.26-0.82. For patients with clinically manifest vascular disease and diabetes, the hazard ratios were 0.56 (95% CI 0.28 - 1.12 and 0.28 (95%CI 0.10 - 0.79 respectively. Conclusion Clinical guidelines for cardiovascular disease management do reduce risk of renal complications in high risk patients. Benefits are seen with attainment of any two treatment targets.

    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.

    Hospital readmission is an adverse patient outcome that is serious, common, and costly. For hospitals, identifying patients at risk for hospital readmission is a priority to reduce costs and improve care. The purposes were to validate a predictive algorithm to identify patients at a high risk for preventable hospital readmission within 30 days after discharge and determine if additional risk factors enhance readmission predictability. A retrospective study was conducted on a randomized sample of 598 patients discharged from a Southeast community hospital. Data were collected from the organization's database and manually abstracted from the electronic medical record using a structured tool. Two separate logistic regression models were fit for the probability of readmission within 30 days after discharge. The first model used the LACE index as the predictor variable, and the second model used the LACE index with additional risk factors. The two models were compared to determine if additional risk factors increased the model's predictive ability. The results indicate both models have reasonable prognostic capability. The LACE index with additional risk factors did little to improve prognostication, while adding to the model's complexity. Findings support the use of the LACE index as a practical tool to identify patients at risk for readmission.

    2008-08-01

    The Heart Outcomes Prevention (HOPE) trial was the first to demonstrate the benefits of the angiotensin-converting enzyme (ACE) inhibitor ramipril for high-risk cardiovascular patients. Whether the cardioprotective effects seen in HOPE and other trials are specific to distinct ACE inhibitors remains controversial. Evidence of a lack of class effect for ACE inhibitors has policy and financial implications related to reference pricing by insurers and inclusion on pharmacy formularies. Because head-to-head trials comparing the different ACE inhibitors are unforeseen, clinicians and administrators must rely on secondary-level data and observational studies. Only a handful of studies have sought to address the dispute over a class effect among ACE inhibitors, which is reviewed in this article.

    Full Text Available The use of iodinated contrast media (CM is integral to the practice of interventional radiology, facilitating visualization of anatomic structures during MDCT guided diagnostic and therapeutic procedures and leading to advances in patient care.The benefits of contrast-enhanced MDCT imaging,"nhowever, must be viewed in the context of the potential risks of CM use, of which contrast-induced nephropathy (CIN may be the most serious. CIN is the third commonest cause of hospital-acquired renal insufficiency, with approximately 33% of these cases attributed to CM use in CT procedures in patients who are at risk of CIN due to the presence of established risk factors. Reported patient risk factors for CIN include age, congestive heart failure, and dehydration but pre-existing renal impairment, particularly in association with diabetes, is generally recognized as the most important variable. Based on this, it is recommended that patients who are to undergo intravenous administration of an iodinated contrast agent be questioned about potential renal dysfunction at the time of referral and those who answer positively to at least 1 question should be screened for elevated serum Cr. When a high-risk patient is identified, several strategies can be implemented to minimize the occurrence of CIN. Cessation of all nephrotoxic medications should be implemented if possible ≥24 hours before the contrast-enhanced CT procedure. Adequate pre-and post-procedural hydration is considered one of the most effective CIN prevention measures. Studies of pharmacological prophylaxis are less encouraging and the role of N-acetylcysteine for CIN prevention, for example, remains unclear to date. Finally, volume and type of CM used during the CT procedure may influence the development of CIN. Findings from randomized controlled trials that have considered the role of CM osmolality on nephrotoxicity in at-risk populations suggest that the iso-osmolar CM iodixanol is reno

    Lung cancer is among the most common cancers worldwide, and the leading cause of cancer death in both men and women. For patients with early stage (AJCC T1-2, N0) non-small cell lung cancer the current standard of care is lobectomy with systematic lymph node evaluation. Unfortunately, medical comorbities often present in patients with lung cancer, may preclude the option of surgical resection . In such cases, a number of minimal to non-invasive treatment options have gained popularity in the treatment of these high-risk patients. These modalities provide significant advantages including patient convenience, treatment in an outpatient setting, and acceptable toxicities including reduced impact on lung function and a modest risk of post-procedure chest wall pain. This manuscript seeks to provide a comprehensive review of the literature including reported outcomes, complications and limitations of sublobar resection with or without intraoperative brachytherapy, radiofrequency ablation, microwave ablation, percutaneous cryoablation, photodynamic therapy and stereotactic body radiation therapy.

    Full Text Available 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.

    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

    Full Text Available Abstract 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.

    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

    There is paucity of information from eastern India with regard to observed dominant micro-organisms causing febrile neutropenia (FN) in patients with haematological malignancies. To identify the prevalence of pathogenic microorganisms associated with FN. A total number of 268 episodes of FN were analysed from September'2010 to October'2013. The blood samples were inoculated into brain heart infusion broth, glucose broth, Hicombi dual performance media (Himedia, LQ-12) at 37° C for 168 h and Bactec method was also performed for these samples. Blood agar, chocolate agar, MacConkey's agar and cystine lactose electrolyte deficient agar were used for isolation of the microorganisms. A total number of 78 (29.10 %) episodes revealed positive growths. Gram negative bacilli and Gram positive cocci were isolated in 61.53 and 34.61 % cases respectively. The eight commonest isolates were Pseudomonas aeruginosa (14.10 %), methicillin resistant Staphylococcus aureus (MRSA-12.82 %), Acinetobacter sps (11.53 %), coagulase negative Staphylococcus (10.25 %), Klebsiella pneumoniae (8.97 %), Escherichia coli (8.97 %), ESBL E. coli (6.41 %), methicillin sensitive S. aureus (MSSA-6.41 %). Amongst other less common isolates were Citrobacter kosseri (3.84 %), Citrobacter freundii (2.56 %), Ralstonia paucula (2.56 %), Cedecia neteri (1.28 %), methicillin resistant coagulase negative Staphylococcus (2.56 %). Candida spp. including two cases of Candida non-albicans was isolated in 3.84 % of cases. P. aeruginosa was the commonest pathogenic isolates in FN patients associated with haematological malignancies in this study. Gram negative bacteria were the commonest isolates in FN including significant numbers of rare opportunistic micro-organisms.

    Haematological cancers differ from other cancers mainly with regard to treatment strategies: surgery is used for diagnostic purposes but rarely for treatment, whereas chemotherapy is of central importance and, in some cases, cures patients. This article reviews studies that examine the relationships between psychosocial factors and quality of life (QoL) in haematological cancer patients. A review of the literature was conducted from the databases 'PsycInfo', 'Medline' and 'Science Direct' using the keywords 'lymphoma', 'leukaemia', 'myeloma', 'quality of life', 'psychosocial factors', 'coping', 'social support', 'personality', 'anxiety,' 'depression', 'locus of control' and 'alexithymia'. Fourteen studies were analysed. One study found positive relationships between sense of coherence and health-related QoL, whereas another showed a positive link between self-esteem and QoL. Another study suggested that a high external health locus of control was related to a better QoL. Fighting spirit had a positive impact on QoL for two studies, and helplessness-hopelessness was positively related to emotional distress in one study. Two studies indicated the relationships between emotional distress and QoL. Satisfaction with information about disease determined emotional distress in another study. Social support, general health perceptions, global meaning or spirituality were found to improve QoL in four other reports. Literature about the relationships between psychosocial factors and QoL is lacking. Sense of coherence, self-esteem and health locus of control, coping strategies, social support, global meaning or emotional distress are associated with QoL. Results concerning coping and social support should be interpreted with caution because of level II evidence in studies. Copyright © 2012 John Wiley & Sons, Ltd.

    Objective The Kyoto gastritis classification categorizes the endoscopic characteristics of Helicobacter pylori (H. pylori) infection-associated gastritis and identifies patterns associated with a high risk of gastric cancer. We investigated its efficacy, comparing scores in patients with H. pylori-associated gastritis and with gastric cancer. Methods A total of 1,200 patients with H. pylori-positive gastritis alone (n=932), early-stage H. pylori-positive gastric cancer (n=189), and successfully treated H. pylori-negative cancer (n=79) were endoscopically graded according to the Kyoto gastritis classification for atrophy, intestinal metaplasia, fold hypertrophy, nodularity, and diffuse redness. Results The prevalence of O-II/O-III-type atrophy according to the Kimura-Takemoto classification in early-stage H. pylori-positive gastric cancer and successfully treated H. pylori-negative cancer groups was 45.1%, which was significantly higher than in subjects with gastritis alone (12.7%, pgastritis scores of atrophy and intestinal metaplasia in the H. pylori-positive cancer group were significantly higher than in subjects with gastritis alone (all pgastritis classification may thus be useful for detecting these patients.

    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).

    AIM: To assess the efficacy and safety of ultrasound guided percutaneous cholecystostomy (PC) in the treatment of acute cholecystitis in a well-defined high risk patients under general anesthesia.METHODS: The data of 27 consecutive patients who underwent percutaneous transhepatic cholecystostomy for the management of acute cholecystitis from January 1999 to June 2003 was retrospectively evaluated. All of the patients had both clinical and sonographic signs of acute cholecystitis and had comorbid diseases.RESULTS: Ultrasound revealed gallbladder stones in 25 patients and acalculous cholecystitis in two patients.Cholecystostomy catheters were removed 14-32 d (mean 23 d) after the procedure in cases where complete regression of all symptoms was achieved. There were statistically significant reductions in leukocytosis, (13.7× 103± 1.3× 103μg/L vs 13× 103± 1× 103μg/L,P<0.05 for 24 h after PC; 13.7 × 103 ± 1.3 × 103 μg/L vs8.3 × 103 ± 1.2 × 103 μg/L, P < 0.0001 for 72 h after PC), C -reactive protein (51.2 ± 18.5 mg/L vs 27.3 ±10.4 mg/L, P < 0.05 for 24 h after PC; 51.2 ± 18.5 mg/Lvs 5.4 ± 1.5 mg/L, P < 0.0001 for 72 h after PC), and fever (38 ± 0.35℃ vs 37.3 ± 0.32℃, P < 0.05 for 24h after PC; 38 ± 0.35℃ vs 36.9 ± 0.15℃, P < 0.0001 for 72 h after PC). Sphincterotomy and stone extraction was performed successfully with endoscopic retrograde cholangio-pancreatography (ERCP) in three patients.After cholecystostomy, 5 (18%) patients underwent delayed cholecystectomy without any complications.Three out of 22 patients were admitted with recurrent acute cholecystitis during the follow-up and recovered with medical treatment. Catheter dislodgement occurred in three patients spontaneously, and two of them were managed by reinsertion of the catheter.CONCLUSION: As an alternative to surgery, percutaneous cholecystostomy seems to be a safe method in critically ill patients with acute cholecystitis and can be performed with low mortality

    The optimal combination drug therapy for hypertension is not established, although current U.S. guidelines recommend inclusion of a diuretic. We hypothesized that treatment with the combination of an angiotensin-converting-enzyme (ACE) inhibitor and a dihydropyridine calcium-channel blocker would be more effective in reducing the rate of cardiovascular events than treatment with an ACE inhibitor plus a thiazide diuretic. In a randomized, double-blind trial, we assigned 11,506 patients with hypertension who were at high risk for cardiovascular events to receive treatment with either benazepril plus amlodipine or benazepril plus hydrochlorothiazide. The primary end point was the composite of death from cardiovascular causes, nonfatal myocardial infarction, nonfatal stroke, hospitalization for angina, resuscitation after sudden cardiac arrest, and coronary revascularization. The baseline characteristics of the two groups were similar. The trial was terminated early after a mean follow-up of 36 months, when the boundary of the prespecified stopping rule was exceeded. Mean blood pressures after dose adjustment were 131.6/73.3 mm Hg in the benazepril-amlodipine group and 132.5/74.4 mm Hg in the benazepril-hydrochlorothiazide group. There were 552 primary-outcome events in the benazepril-amlodipine group (9.6%) and 679 in the benazepril-hydrochlorothiazide group (11.8%), representing an absolute risk reduction with benazepril-amlodipine therapy of 2.2% and a relative risk reduction of 19.6% (hazard ratio, 0.80, 95% confidence interval [CI], 0.72 to 0.90; P<0.001). For the secondary end point of death from cardiovascular causes, nonfatal myocardial infarction, and nonfatal stroke, the hazard ratio was 0.79 (95% CI, 0.67 to 0.92; P=0.002). Rates of adverse events were consistent with those observed from clinical experience with the study drugs. The benazepril-amlodipine combination was superior to the benazepril-hydrochlorothiazide combination in reducing cardiovascular

    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.

    Combination of mannan antigen and anti-mannan antibody (Mn/A-Mn) testing has been reported a useful and specific strategy for diagnosis of invasive Candida infections (ICIs). We evaluated Mn/A-Mn as a screening tool in patients with haematological malignancies. This clinical prospective study was performed at the Division of Hematology, Medical University Graz, Austria between July and December 2012. Patients at risk for fungal infection were included into the study and twice weekly screened by Mn/A-Mn testing, yielding 650 samples. Of overall 67 patients 66 had no evidence for ICI. From those, 153/640 serum samples (23.9%) were positive for mannan Ab, and nine (1.4%) for Ag. Most false positive Ab results were observed among 375 samples from patients without haematopoietic stem cell transplantation (34.9% resulted positive). Combined specificity of Mn/A-Mn was 74.8%. Of 10 samples obtained in the single patient with candidemia, five were positive for mannan Ag (from the day of diagnosis up to 40 days after detection of candidemia) and none for Ab. In conclusion, mannan Ab screening yielded a high number of false positive results. While mannan Ag was found to be highly specific and may have potential for diagnostic driven testing, mannan Ab testing cannot be recommended based on our study results. © 2016 Blackwell Verlag GmbH.

    Plasmapheresis also known as a therapeutic plasma exchange (TPE) is a procedure of plasma removal with it's ineligible plasma's component. Usually it is a supportive measure used simultaneously with the treatment, but in a few diseases, e.g. in trombotictrombocytopenic purpura (TTP), it is a first-choice treatment. During the plasmapheresis plasma is mostly replaced by 20% solution of albumin or combination of 20% solution of albumin and 0.9% solution of NaCl, however in some diseases fresh frozen plasma (FFP) is used. Plasmaphereses have found a wide application in different branches of medicine: hematology, neurology, nephrology, reumatology. Plasmapheresis is an invasive procedure, but when performed by qualified staff it is rather safe and serious complications are very rare.The most common complications of plasmapheresis are mild, usually caused by electrolyte disturbances (hypokalemia, hypokalcemia) or anticoagulation. More serious complication can be associated with FFP transfusion, extracorporeal circulation or presence of intravenous catheter. The latter one is usually necessary to perform the plasmapheresis. In haematology the most common indication for plasmapheresis is the supportive treatment of multiple myeloma. The procedure is performed in patients with high protein levels endangered with hyperviscosity syndrome. Less frequent indications to plasmapheresis in haematology are: Waldenström's macroblobulynaemia, idiopathic thrombocytopenic purpura (ITP), pure red cell aplasia (PRCA), polyneuropaties connected with haematological disorders. Supportive treatment of haemofagocytic syndrome (HLH--hemophagocytic lymphohistiocytosis) is one of the new indications. Plasmaphereses are used in treatment of about 150 different diseases and more and more new needs for this method are identified.

  13. Pilot Clinical Trial of Indocyanine Green Fluorescence-Augmented Colonoscopy in High Risk Patients

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

    Carotid angioplasty and stenting (CAS) is used in patients considered high-risk for carotid endarterectomy (CEA). Patients qualify as high-risk because of medical comorbid conditions or for anatomic considerations (previous CEA, radical neck dissection, radiation). We compared the technical feasibility and durability of CAS in medically high-risk patients (MED) vs anatomically high-risk patients (ANAT). A retrospective review was performed of all consecutive patients undergoing CAS by a single vascular surgery group. All patients were high risk and evaluated with duplex ultrasound imaging and angiography. Primary end points were technical success, 30-day stroke, myocardial infarction (MI), death, and in-stent restenosis. Standard statistical analysis included Kaplan-Meier life tables. From January 2003 to December 2007, 230 CAS (98 ANAT, 132 MED) procedures were attempted. The ANAT cohort comprised 84 patients with a single anatomic risk factor: 71 with a previous ipsilateral CEA, 6 high lesions, 6 history of neck radiation, and 1 with a tracheostomy. Ten patients had two or three anatomic risk factors: nine with radical neck dissection and radiation and one with neck radiation and ipsilateral CEA. The mean age was 71.1 years for ANAT vs 73.9 years for MED (P = .021). Technical success rates were 98% in ANAT and 98.5% in MED (P = .76). Thirty-day stroke rate was 1.0% in ANAT and 5.3% in MED (P = .14); the mortality rate was 2.0% in ANAT and 0.8% in MED (P = .79). The 2-year survival free from stroke was MED, 93.6% and ANAT, 98.9% (P = .118); and from restenosis was MED, 91.9%; and ANAT, 91.0% (P = .98). Two-year overall survival was significantly better in ANAT (84.6%) vs MED (70.1%; P = .026). Four of the seven restenoses in the ANAT group occurred in patients with previous neck radiation. The restenosis rate for radiation-induced (RAD) stenosis treated with CAS was significantly higher at 22.2% (4 of 18) compared with 3.8% (3 of 78) in ANAT group patients without

    Conclusions: The presence of large esophageal varices is the most important predictive risk factor for the occurrence of VB, independently of the class of Child-Pugh. Additionally, the portal vein diameter ≥ 13 mm is a non-invasive parameter related to high risk of VB. Therefore, these factors could be used as predictors of high risk of VB when the measure of HPVG is not available.

It also gives a firsthand look at fatal versus nonfatal CV events. Methods: The MarketScan® Commercial Claims and Encounters Database was used to identify adults with a CV event in 2006–2012 with hyperlipidemia or lipid-lowering therapy use in the 18 months prior to one of the following inpatient CV events: myocardial infarction, ischemic stroke, unstable angina, transient ischemic attack, percutaneous coronary intervention, or coronary artery bypass graft (CABG. Patients were required to have a preindex diagnosis of at least one of the following: peripheral arterial disease, abdominal aortic aneurysm, carotid artery disease, or diabetes. A subset analysis was conducted with patients with data linkable to the Social Security Administration Master Death File. Direct medical costs were reported for each quarter following a CV event, for up to 36 months after the first CV event. Results: In total, 38,609 CHD-RE patients were included, mean age 57 years, 31% female. CABG, myocardial infarction, and percutaneous coronary intervention were the most frequent and most expensive first CV events, accounting for >75% of all first CV events with mean first quarter costs ranging from $17,454 (nonfatal transient ischemic attack to $125,690 (fatal CABG. Overall, 15% of those with a first CV event went on to have a second event during the 36-month study period with mean first quarter nonfatal and fatal costs similar to first event levels. Third CV events were rare, happening in less than 3% of patients. Conclusion: CV events among CHD-RE patients were

    The purpose of this study was to evaluate the use of combined transmission and emission tomography (TET) for correct localisation of heterotopic splenic tissue and differentiation of splenosis from other masses. The TET technique comprises the fusion of SPET and CT data obtained using the same imaging device to allow perfect overlap of anatomical and functional images. TET was performed in seven patients who either had haematological disorders and relapsing anaemia or thrombocytopenia after splenectomy or were under immunosuppression for different reasons. These patients presented 20 equivocal lesions on CT or MRI. Presence of splenic tissue was investigated using technetium-99m labelled colloids or heat-damaged red blood cells. Findings of spleen scintigraphy, TET and CT or MRI were compared with respect to localisation of splenosis and correct classification of lesions by CT or MRI. Histological validation was achieved by surgery or biopsy in all cases. All 20 lesions demonstrated by CT or MRI were correctly classified by TET as splenosis. Three additional lesions initially overlooked by CT or MRI could be detected. Diagnostic relevance was highest for intrahepatic, intrapulmonary or pleural splenic implants. It is concluded that TET allows exact localisation of heterotopic splenic tissue in patients with suspected splenosis. (orig.)

    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.

    with hypertension and dyslipidemia had pre-post increases in MPR of 2.29% and 2.10%, respectively, while the control group had decreases of 2.31% and 2.61% (both P  less than  0.001). The mean MPRs for members with diabetes, depression, and asthma did not change in either group. Program costs per patient in 2009 were estimated to be $478. The program had a return on investment (ROI) of 2.0 in 2009. This study found that the pharmacist-managed MTM program to reconcile the medication therapies of high-risk patients and improve adherence, as measured by MPR, was effective in reducing total health care costs. The results show that those patients in the intervention group with hypertension and dyslipidemia had significant improvements in medication adherence, as compared with the control group. In fact, the intervention group used significantly more days of therapy in the intervention period, and the control group used significantly fewer days than either group used during the baseline period. MTM interventions were associated with a significant decrease in the MTM members' overall plan-paid health care costs, driven largely by decreases in inpatient utilization and mediated by increases in average days supply and in MPR increases for hypertension and dyslipidemia. Overall, the MTM program was cost-effective. The ROI estimated for this program of 2.0 is only slightly lower than the average disease management ROIs reported in the literature.

    Vacuum-assisted closure(VAC) therapy is mainly used for tissue defects. VAC therapy can remove exudate that could impair the healing process. We applied VAC therapy in patients considered at high risk of surgical site infection who underwent cardiovascular surgery via standard median sternotomy. Risk factors included advanced heart failure, obesity, diabetes mellitus, steroid administration, immunosuppressant administration, and chronic renal failure, etc. VAC therapy was used in 134 patients. Only 3 of these patients (2.2%) developed surgical site infection caused by Staphylococcus epidermidis;2 patients fully recovered after prolonged VAC therapy for 2 weeks, and the other required an additional sternal fixation after the sternal wires were removed for wound infection control. No patient developed infective mediastinitis. Prophylactic VAC therapy can reduce postoperative wound infection in high risk patients undergoing open heart surgery via full sternotomy.

  2. Strategies for screening for pancreatic adenocarcinoma in high-risk patients.

    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.

    The aim of this study was to assess the impact on practice of vena cava filter insertion guidelines (Eastern Association for the Surgery of Trauma: practice management guidelines). The study was performed at a level 1 trauma centre with data from the 'Trauma Audit and Research Network' cross-referenced to hospital data. A total of 1138 specific 'high-risk' major trauma patients were identified over a 6-year period. The mean age was 46 years (18-102) and the male to female ratio was 3.3:1. The average Injury Severity Score was 23.6 (4-75). The overall DVT rate was 2.6% and the PE rate was 1.8%. A retrievable IVC filter was inserted in 42 cases (3.8%). The filter retrieval rate was 23.8% at a mean of 68.5days (4-107). Only one complication was reported of a breakthrough PE despite filter. Applying the EAST guidelines to this cohort would have suggested filter insertion in 279 (24.6%) cases. The kappa concordance value between observed practice and the 'EAST filter group' was 0.103 (poor). The PE rate in the 'EAST filter group' was 2.2% vs 1.6% in the 'no filter group' (p=0.601, no statistical difference) and the observed odds ratio was 0.814 (95% CI 0.413, 1.602). The EAST guidelines are useful but may be overestimating the need for filter insertion. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Conclusions: Among high risk patients with recurrent symptoms, the short term rate of progression of CAD is high. A drop in LVEF >5% is the best predictor of progression of CAD. Further studies are needed to determine the prognostic value of CAD progression in the era of potent medical therapy.

    The Fifth European Conference on Infections in Leukaemia (ECIL-5) convened a meeting to establish evidence-based recommendations for using tests to diagnose Pneumocystis jirovecii pneumonia (PCP) in adult patients with haematological malignancies. Immunofluorescence assays are recommended as the most sensitive microscopic method (recommendation A-II: ). Real-time PCR is recommended for the routine diagnosis of PCP ( A-II: ). Bronchoalveolar lavage (BAL) fluid is recommended as the best specimen as it yields good negative predictive value ( A-II: ). Non-invasive specimens can be suitable alternatives ( B-II: ), acknowledging that PCP cannot be ruled out in case of a negative PCR result ( A-II: ). Detecting β-d-glucan in serum can contribute to the diagnosis but not the follow-up of PCP ( A-II: ). A negative serum β-d-glucan result can exclude PCP in a patient at risk ( A-II: ), whereas a positive test result may indicate other fungal infections. Genotyping using multilocus sequence markers can be used to investigate suspected outbreaks ( A-II: ). The routine detection of dihydropteroate synthase mutations in cases of treatment failure is not recommended ( B-II: ) since these mutations do not affect response to high-dose co-trimoxazole. The clinical utility of these diagnostic tests for the early management of PCP should be further assessed in prospective, randomized interventional studies.

    Full Text Available We present our first experience with endovascular treatment of 6 subclavian artery aneurysms (SAA occurring in five male and one female patient. All patients, in our studies, according to ASA classification were high risk for open repair of SAA. The etiology of the all aneurysms was atherosclerosis degeneration of the artery. Two aneurysms were of intrathoracic location, then the other were extrathoracic. Symptoms related to subclavian artery aneurysms were present in two patients, compression and chest pain in one, and hemorrhage shock in second, while the remaining patients were asymptomatic. We preferred the Viabhan endoprosthesis for endovascular repair in 5 cases. In one patient with ruptured of subclavian artery aneurysm who was high-risk for open repair we made combined endovascular procedure. First at all, we covered the origin of left subclavian artery with thoracic stent graft and after that we put two coils in proximal part of subclavian artery. There was no operative mortality, and the early patency rate was 100%. The follow-up period was from 3 months to 3 years. During this period, one patient died of heart failure and one patient required endovascular reoperation due to endoleak type I. Endovascular treatment is recommended for all patients with subclavian artery aneurysm whenever this is possible due to anatomical reasons especially in high-risk patient with intrathoracic localization of aneurysm, to prevent potential complications.

    Vascular complications (VC) following transcatheter aortic valve replacement (TAVR) are associated with worse outcomes. The trend of VC incidence in patients considered high risk is unclear. We sought to assess the trend of VC after TAVR in patients at high risk. We investigated the VC trend in female, diabetes mellitus, and peripheral vascular disease (PVD) patients. Patients who underwent TAVR from 2011 to 2014 in the United States were identified using the International Classification of Diseases-Ninth Revision code 35.05 from the Nationwide Inpatient Sample database. Frequency of any VC (per 100 transcatheter aortic valve implantation procedure or hospital discharges) for each year from 2011 to 2014 was assessed for the overall population as well as within each category of high-risk cohorts. The overall VC rate was 6.0% (2,044/33,790). Patients who had VC were more likely to be female and had higher rates of PVD at baseline. The annual rate of VC in the overall population from 2011 to 2014 was 4.6%, 9.4%, 6.8%, and 4.4%, respectively. There was a significant increase in VC rate from 2011 to 2012 (p = 0.03), whereas there was a significant decrease in VC rate from 2012 to 2014 (p <0.001). The rate of VC between 2011 and 2014 was similar (p = 0.82). The rate of VC did not increase in any of the high-risk groups from 2011 to 2012. However, the rate of VC from 2012 to 2014 decreased significantly in all the high-risk groups. The VC rate was similar for groups between 2011 and 2014. The overall VC rate among TAVR patients initially increased from 2011 to 2012 but decreased thereafter. Similar trend in VC rate was found among high-risk patients except that the initial increase in rates from 2011 to 2012 did not reach statistical significance. Whether further reduction in VC with improvement in devices and operator/center experience for both overall and high-risk groups in TAVR occurs will require continuous longitudinal monitoring.

    Nonvariceal upper gastrointestinal bleeding (NVUGIB) is a potentially life-threatening hospital emergency requiring hemodynamic stabilization and resuscitation. This study is carried out to determine whether hospital volume can influence outcome in patients with NVUGIB. This is a retrospective study with a prospective cohort database (KCT 0000514. cris.nih.go.kr). Eight teaching hospitals were divided into two different groups: high-volume centers (HVC, ≥60 NVUGIB patients/year, four clinics) and low-volume centers (LVC, bleeding after treatment, re-bleeding, necessity for surgical/other retreatments, and death within 30 days. Similar baseline characters for patients were observed in both groups. There was a significant difference in the incidence of poor outcome between the HVC and LVC groups (9.06 vs. 13.69%, P = 0.014). The incidence rate of poor outcome in high-risk patients (Rockall score ≥8) in HVC was lower than that in high-risk patients in LVC (16.07 vs. 26.92%, P = 0.048); however, there was no significant difference in poor outcome in the lower-risk patients in either group (8.72 vs. 10.42%, P = 0.370). Significant correlation between hospital volume and outcome in NVUGIB patients was observed. Referral to HVC for the management of high-risk NVUGIB patients should be considered in clinical practice.

    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.

  13. The incidence of deep venous thrombosis in high-risk Indian neurosurgical patients: Need for early chemoprophylaxis?

    Directory of Open Access Journals (Sweden)

    Ajith John George

    2016-01-01

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

    Patients with newly diagnosed high-risk (HR) neuroblastoma (NBL) still have a poor outcome, despite multi-modality intensive therapy. This poor outcome necessitates the search for new therapies, such as treatment with (131)I-meta-iodobenzylguanidine ((131)I-MIBG). To assess the efficacy and adverse effects of (131)I-MIBG therapy in patients with newly diagnosed HR NBL. We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library 2016, Issue 3), MEDLINE (PubMed) (1945 to 25 April 2016) and Embase (Ovid) (1980 to 25 April 2016). In addition, we handsearched reference lists of relevant articles and reviews. We also assessed the conference proceedings of the International Society for Paediatric Oncology, Advances in Neuroblastoma Research and the American Society of Clinical Oncology; all from 2010 up to and including 2015. We scanned the International Standard Randomized Controlled Trial Number (ISRCTN) Register (www.isrctn.com) and the National Institutes of Health Register for ongoing trials (www.clinicaltrials.gov) on 13 April 2016. Randomised controlled trials (RCTs), controlled clinical trials (CCTs), non-randomised single-arm trials with historical controls and cohort studies examining the efficacy of (131)I-MIBG therapy in 10 or more patients with newly diagnosed HR NBL. Two review authors independently performed the study selection, risk of bias assessment and data extraction. We identified two eligible cohort studies including 60 children with newly diagnosed HR NBL. All studies had methodological limitations, with regard to both internal (risk of bias) and external validity. As the studies were not comparable with regard to prognostic factors and treatment (and often used different outcome definitions), pooling of results was not possible. In one study, the objective response rate (ORR) was 73% after surgery; the median overall survival was 15 months (95% confidence interval (CI) 7 to 23

    Unplanned readmissions may be avoided by accurate risk prediction and appropriate resources could be allocated to high risk patients. The Length of stay, Acuity of admission, Charlson comorbidity index, Emergency department visits in past six months (LACE) index was developed to predict hospital readmissions in Canada. In this study, we assessed the performance of the LACE index in a Singaporean cohort by identifying elderly patients at high risk of 30-day readmissions. We further investigated the use of additional risk factors in improving readmission prediction performance.Data were extracted from the hospital's electronic health records (EHR) for all elderly patients ≥ 65 years, with alive-discharge episodes from Singapore General Hospital in 2014. In addition to LACE, we also collected patients' data during the index admission, including demographics, medical history, laboratory results, and previous medical utilization.Among the 17,006 patients analyzed, 2051 or 12.1% of them were observed 30-day readmissions. The final predictive model was better than the LACE index in terms of discriminative ability; c-statistic of LACE index and final logistic regression model was 0.595 and 0.628, respectively.The LACE index had poor discriminative ability in identifying elderly patients at high risk of 30-day readmission, even if it was augmented with additional risk factors. Further studies should be conducted to discover additional factors that may enable more accurate and timely identification of patients at elevated risk of readmissions, so that necessary preventive actions can be taken.

    Thrombopoietin (TPO) isolated from thrombocytopenic plasma of various animal species has previously been shown to comprise only truncated forms of the molecule, presumably generated by proteolysis. Native TPO has now been partially purified from normal human plasma by immunoaffinity chromatography and was confirmed to be biologically active. Gel filtration in the presence of SDS revealed that TPO eluted in two peaks: a major peak corresponding to the elution position of fully glycosylated recombinant human TPO (rhTPO) consisting of 332 amino acid residues, and a minor peak corresponding to a smaller molecular size. Immunoblot analysis also revealed that most plasma-derived TPO migrated at the same position as fully glycosylated rhTPO, corresponding to a molecular size of approximately 80 to 100 kDa. Furthermore, the size distribution of circulating TPO in patients with various haematologic disorders did not differ markedly from that of plasma-derived TPO from healthy individuals. These results indicate that the truncation of circulating TPO is not related to disease pathophysiology, and that the predominant form of TPO in blood is a biologically active approximately 80- to 100-kDa species. The size distribution of TPO extracted from normal platelets was similar to that of TPO in plasma; the proportion of truncated TPO was decreased by prior incubation of platelets with hirudin. indicating that the endogenous truncated TPO, at least in platelet extract, was generated by thrombin-mediated cleavage.

    The 5th European Conference on Infections in Leukaemia (ECIL-5) meeting aimed to establish evidence-based recommendations for the prophylaxis of Pneumocystis jirovecii pneumonia (PCP) in non-HIV-infected patients with an underlying haematological condition, including allogeneic HSCT recipients. Recommendations were based on the grading system of the IDSA. Trimethoprim/sulfamethoxazole given 2-3 times weekly is the drug of choice for the primary prophylaxis of PCP in adults ( A-II: ) and children ( A-I: ) and should be given during the entire period at risk. Recent data indicate that children may benefit equally from a once-weekly regimen ( B-II: ). All other drugs, including pentamidine, atovaquone and dapsone, are considered second-line alternatives when trimethoprim/sulfamethoxazole is poorly tolerated or contraindicated. The main indications of PCP prophylaxis are ALL, allogeneic HSCT, treatment with alemtuzumab, fludarabine/cyclophosphamide/rituximab combinations, >4 weeks of treatment with corticosteroids and well-defined primary immune deficiencies in children. Additional indications are proposed depending on the treatment regimen.

    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.

    Objective: To study the relationship between high risk HPV infection and potential malignant biological behavior of patients with cervical intraepithelial neoplasia. Methods: Patients with cervical intraepithelial neoplasia treated in our hospital from May 2012 to May 2014 were chosen for study; 40 cases of patients each in CIN I stage, CIN II stage and CIN III stage were screened; HPV subtypes as well as mRNA contents of proliferation related genes and chromosome related genes were detected. Results: (1) HPV subtypes: there were no differences in positive rates and contents of HPV-31, 33, 51, 52 and 58 of patients in different CIN stages; there were differences in positive rates and contents of HPV-16 and 18, and the higher the CIN stage is, the higher the positive rates and contents of HPV-16 and 18 are; (2) Proliferation related genes: mRNA contents of proliferation genes IMP3, MUC1 and TS in cervical tissue of patients with high risk HPV infection displayed higher expressions; mRNA contents of tumor suppressor genes p16ink4a and p53 displayed lower expressions; (3) Chromosome related genes: mRNA contents of MCM2, MCM7, hTERC, hTERT, hTP1 and CA-IX in cervical tissue of patients with high risk HPV infection displayed higher expressions. Conclusion: HPV-16 and 18 are high risk HPV of patients with cervical intraepithelial neoplasia and will cause increased expressions of proliferation genes and inhibited expressions of tumor suppressor genes, and affect chromosome replication and extension process.

    The objective of this study is to assess the prognostic usefulness of the Multinational Association of Supportive Care in Cancer (MASCC) risk score in association with the value of C-reactive protein (CRP) to identify high-risk patients with febrile neutropenia and hematologic neoplasms. A retrospective cohort study in which the MASCC score and the CRP values were used to assess the mortality risk at 30 days among patients with febrile neutropenia and hematologic malignancies was performed. Two hundred thiry-seven patients with febrile neutropenia were analyzed; the mortality rate within 30 days was 9 %. High-risk patients according to the MASCC score were significantly more likely to experience adverse outcomes, such as being transferred to the intensive care unit (RR 3.55; CI 95 % 2.73-6.62, p risk group identified by the MASCC score (HR 3.0; CI 95 % 1.12-13.54, p = 0.032) and the mean levels of CRP (HR 17; CI 95 % 2.21-136.48, p = 0.007) and survival. The survival rate within 30 days was 100 % for the patients with a low-risk MASCC score and a mean CRP less than 15 mg/dL. This rate was only 64 % for high-risk patients with a mean CRP greater than 15 mg/dL. The MASCC risk score combined with the mean CRP value successfully identifies patients with febrile neutropenia and hematological malignancies and a high risk of death.

    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

    This project was done at specialist cancer hospital in Qatar. At a haematology-oncology inpatient department most patients were not getting access to palliative care unless they were at the very end stages of life. Data collected from 2008-2011 showed significant numbers of patients were dying within one month of their transfer to palliative care. There was no standard measure to identify the prospective palliative care patients. A multidisciplinary team developed a Palliative care referral screening tool based on the National Cancer Care Network guideline. Retrospective medical record review done from January to April 2012 showed a mean of 68% of patients who scored more than five were not consulted, 32% of patients who scored more than seven were not transferred to palliative care and seven percent died without any referral. The team used various kinds of quality planning, analysis and improvement tools in the form of process mapping, value analysis, Fish Bone diagrams, stakeholders' analysis and communication, physician survey, "Pareto's principal" (80 / 20 rule, the law of vital few) and other data collection tools. The palliative care referral process was standardised by preparing and implementing an objective scoring tool based on international best practice. It changed the referral culture and helped manage the psychological barriers of patients, families and caregivers. Extensive orientation and education of all key stakeholders was implemented. Monthly auditing of patient records was carried out. The aim has been achieved, exceeded and sustained, and we reduced the percentage of patients who scored more than five without palliative consultation from a mean of 68% to 16% and those who scored more than seven without palliative care transfer from a mean of thirty two percent to three percent, after four months of the project's implementation. Standardising the referral process and creating an objective referral tool is needed to facilitate safe, collaborative

    Full Text Available Abstract Background A small percentage of high-risk patients accounts for a large proportion of Medicaid spending in the United States, which has become an urgent policy issue. Our objective was to pilot a novel patient-centered intervention for high-risk patients with frequent hospital admissions to determine its potential to improve care and reduce costs. Methods Community and hospital-based care management and coordination intervention with pre-post analysis of health care utilization. We enrolled Medicaid fee-for-service patients aged 18-64 who were admitted to an urban public hospital and identified as being at high risk for hospital readmission by a validated predictive algorithm. Enrolled patients were evaluated using qualitative and quantitative interview techniques to identify needs such as transportation to/advocacy during medical appointments, mental health/substance use treatment, and home visits. A community housing partner initiated housing applications in-hospital for homeless patients. Care managers facilitated appropriate discharge plans then worked closely with patients in the community using a harm reduction approach. Results Nineteen patients were enrolled; all were male, 18/19 were substance users, and 17/19 were homeless. Patients had a total of 64 inpatient admissions in the 12 months before the intervention, versus 40 in the following 12 months, a 37.5% reduction. Most patients (73.3% had fewer inpatient admissions in the year after the intervention compared to the prior year. Overall ED visits also decreased after study enrollment, while outpatient clinic visits increased. Yearly study hospital Medicaid reimbursements fell an average of $16,383 per patient. Conclusions A pilot intervention for high-cost patients shows promising results for health services usage. We are currently expanding our model to serve more patients at additional hospitals to see if the pilot's success can be replicated. Trial registration

    We have previously demonstrated that the risk of incisional surgical site infection (SSI) increases with obesity and that the most useful predictor of incisional SSI is the thickness of subcutaneous fat. Based on this finding, we have recently attempted a closure technique in surgery for the obese in which a subcutaneous drain is inserted for the prevention of incisional SSI. The aim of this study was to assess the utility of a subcutaneous drain for preventing incisional SSI in patients undergoing colorectal surgery who are at high risk for incisional SSI. Seventy-nine patients who underwent colorectal resection with high risk for incisional SSI, including patients with obesity (thick subcutaneous fat tissue, >20 mm) and those undergoing emergency operations, were enrolled in this study. The clinical features of these cases with or without a subcutaneous drain were reviewed, and statistical analysis was performed. In these high-risk cases, the overall incidence of incisional SSI was 27.8%. The incidences of incisional SSI in these cases with or without a subcutaneous drain were 14.3% and 38.6%, respectively. Our results suggest that subcutaneous drains are effective for preventing incisional SSI in patients with thick subcutaneous fat in colorectal surgery. Therefore, incisional SSI surveillance for obese patients should be performed separately, which should lead to a further reduction in incisional SSIs.

    Hypertension affects approximately 26% of the world's adult population and is a recognized major risk factor for morbidity and mortality associated with cardiovascular, cerebrovascular, and renal diseases. However, despite the availability of a range of effective antihypertensive agents and a growing awareness of the consequences of high blood pressure (BP), the treatment and control of hypertension remains suboptimal. A number of patient subgroups are categorized as 'high risk' and may have hypertension that is more difficult to treat, including obese individuals, patients with stage 2 hypertension, those with type 2 diabetes mellitus (T2DM), patients with coronary artery disease or a history of stroke, and Black patients. As the benefits of lowering BP in patients with hypertension are unequivocal, particularly in high-risk patients, treating high-risk patients with hypertension to BP goals and maintaining 24-hour BP control is important to help reduce cardiovascular risk and improve outcomes. Although the BP goals recommended in current consensus guidelines for the management of patients with hypertension are based on cuff BP measurements, ambulatory BP monitoring (ABPM) provides a valuable diagnostic tool and allows a more accurate assessment of BP levels throughout the 24-hour dosing period. ABPM is a better predictor of prognosis than office BP measurement and is also useful for assessing whether antihypertensive therapy remains effective in the critical last few hours of the dosing period, which usually coincides with the morning BP surge associated with arousal and arising. ABPM has been adopted by new evidence-based guidelines in the United Kingdom to confirm a suspected diagnosis of hypertension, which is an indication of the growing importance of ABPM in the management of hypertension. This review provides an overview of the efficacy and safety of antihypertensive therapy based on olmesartan medoxomil ± hydrochlorothiazide and amlodipine

    Patients with atherosclerotic renovascular disease (ARVD) and high-risk clinical presentations have largely been excluded from randomized controlled trials comparing renal revascularization and optimal medical therapy. Here, we explore the effect of revascularization on death, progression to end-stage kidney disease (ESKD) and cardiovascular events (CVE) in a highly selected cohort of patients with ARVD. All patients with a radiological diagnosis of ARVD referred to our tertiary centre have been recruited into a single-centre cohort study between 1986 and 2014. Patients with ≥70% unilateral or bilateral ARVD together with one or more of the following putative high-risk presentations were designated 'high-risk': flash pulmonary oedema (FPE), severe hypertension, rapidly deteriorating renal function. The effect of revascularization on clinical outcomes in high-risk patients, patients with bilateral severe ARVD and those with <1 g proteinuria at baseline was compared with 'control' patients who had the same degree of renal artery stenosis (RAS) but did not exhibit these features. Median follow-up was 58.4 months [interquartile range (IQR) 25.4-97.3]. Revascularization was associated with a reduced risk of progression to ESKD, CVE and all combined events in patients with rapidly deteriorating renal function [ESKD: hazard ratio (HR) 0.47 (95% confidence interval, CI, 0.25-0.85), P = 0.01; CVE: HR 0.51 (95% CI 0.29-0.91), P = 0.02; Any: HR 0.51 (95% CI 0.29-0.90), P = 0.02]. High-risk patients with bilateral ≥70% RAS and those with <1 g/day baseline proteinuria also had significantly better renal and cardiovascular outcomes post-revascularization when compared with controls. Our results indicate that revascularization may be of benefit in patients with anatomically significant RAS who present with rapidly deteriorating renal function, especially in the presence of severe bilateral ARVD or <1 g/day proteinuria.

    Full Text Available Background: Cryptosporidium is an important enteric parasite which causes diarrheal illness in humans and animals worldwide. With attention to the role of cryptosporidium in producing diarrhea and mortality in immunocopromised patients and children under 5 years of age, the present study was designed to identify the prevalence of cryptosporidium and potential risk factors in Isfahan province. Methods: This descriptive study was done in Isfahan province from October 2003 to April 2004. A total of 642 children under 5 years of age, immunocompromised patients and high risk persons selected randomly and their stool samples were studied microscopically using Sheater's Sucrose Flotation technique and stained by modified Ziehl-Neelsen staining method. Results: The overall prevalence of cryptosporidium was 4.7% (30 samples. The prevalence rates of infection were 4.6%, 3.5% and 5.4% in children under 5 years of age, immunocompromised patients and high risk persons, respectively. The highest prevalence of infection (6.2% belonged to 1-2 years old children in the group of under 5 years of age, 3-4 years in immunocompromised patients group and 5-10 years in high risk persons group (10%, 6.2% and 14.8% respectively. Conclusion: Cryptosporidium is significantly prevalent in children under 5 years of age, immune compromised patients and high risk persons in Isfahan province. Therefore, health policy makers have to design a plan to identify and treat infected subjected with cryptosporidium thus as a result the transmission of the disease can be prevented in the society.

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

    This pilot randomized controlled trial examined the effect of prophylactic dressings to minimize sacral pressure injuries (PIs) in high-risk hospitalized patients and assessed feasibility criteria to inform a larger study. Eighty patients were recruited at admission points (the emergency department and surgical care unit) or directly from participating wards in the general medical-surgical setting following the assessment of high risk of sacral PI. Participants were randomized into either the routine care or routine care and silicone foam border dressing group. Outcome assessment comprised digital photographs of each participant's sacrum every 72 hr for evaluation by a blind-to-intervention assessor. Sixty-seven participants had at least one sacral photograph taken and assessed by a blind-to-intervention assessor. Three participants were assessed as having a Stage I PI. Although the use of photography was effective, feasibility criteria identified challenges related to bias, blinding, weight assessment, preparation of nursing staff, and sample size estimation.

    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.

    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.

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

    No-shows, or missed appointments, are a problem for many medical practices. They result in fragmented care and reduce access for all patients. To determine whether telephone reminder calls targeted to patients at high risk of no-show can reduce no-show rates. Single-center randomized controlled trial. A total of 2247 primary care patients in a hospital-based primary care clinic at high risk of no-show (>15 % risk) for their appointment in 7 days. Seven days prior to their appointment, intervention arm patients were placed in a calling queue to receive a reminder phone call from a patient service coordinator. Coordinators were trained to engage patients in concrete planning. All patients received an automated phone call (usual care). Primary outcome was no-show rate. Secondary outcomes included arrival rate, cancellation rate, reschedule rate, time to cancellation, and change in revenue. The no-show rate in the intervention arm (22.8 %) was significantly lower (absolute risk difference -6.4 %, p < 0.01, 95 % CI [-9.8 to -3.0 %]) than that in the control arm (29.2 %). Arrival, cancellation, and reschedule rates did not differ significantly. In the intervention arm, rescheduling and cancellations occurred further in advance of the appointment (mean difference, 0.35 days; 95 % CI [0.07-0.64]; p = 0.01). Reimbursement did not differ significantly. A phone call 7 days prior to an appointment led to a significant reduction in no-shows and increased reimbursement among patients at high risk of no-show. The use of targeted interventions may be of interest to practices taking on increased accountability for population health.

    Full Text Available Abstract 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.

    Full Text Available OBJECTIVE: Malarial infection is a major health problem in many parts of India. Several factors have been attributed to increased morbidity and mortality in malaria with altered hematological and hepatic parameters playing an important role. Our aim is to study the clinical, hematological and hepatic manifestations in patients with falciparum malaria. METHODS: This observational study was conducted from November 2012 to October 2013 at Kempegowda Institute of Medical Science and Research Hospital Bangalore. 75 patients of falciparum malaria confirmed by PS, MPQBC positive for Plasmodium falciparum or both falciparum and vivax were included in the study. All patients underwent detailed clinical history, thorough physical examination and investigated with hematological and hepatic parameters. This was followed by monitoring the outcome of the patients with respect to morbidity and mortality. Data was analyzed with descriptive statistical tools. RESULT: Of the 75 patients fever was present in all cases. Pallor (62% was the most common sign followed by splenomegaly (58% and icterus (48%. Anemia (60% was the most common complication, followed by jaundice (44%, cerebral malaria (40%, ARF (25%, ARDS (12%. 12 patients had severe anemia (Hb% <6 gm %. Severe thrombocytopenia (<50, 000 mm3 was seen in 5% of the patients. PT and APTT were increased in 23% and 12% of the cases respectively. 2 patients in the study expired. CONCLUSION: Clinical manifestations of plasmodium falciparum infection ranged from only fever to severe complications including cerebral malaria, acute renal failure, acute hemolytic crisis and hepatic dysfunction. Acute onset fever and splenomegaly were most common clinical manifestations found. Severe Anemia and jaundice are poor prognostic factor and has adverse outcome. Thrombocytopenia increased PT; aPTT does not have any correlation to mortality

    This paper studies the prevalence of platelet antibody in multiply-transfused leukaemia and other transfusion-dependent non-leukaemic patients, using a solid phase red cell adherence (SPRCA) assay and a microlymphocytotoxicity (LCT) test. A positivity rate of 26% in the leukaemic patients and 72% in non-leukaemic patients was obtained with the SPRCA assay, compared to a higher positivity rate of 69% and 83% in the respective groups using the LCT test. Several explanations are proposed. The lower sensitivity of the SPRCA assay suggests that the LCT test may need to be run concurrently for higher diagnostic yield. This paper also compares the performance between an in-house SPRCA test method and the commercial Capture P test kit, and good concordance was shown in repeated occasions.

    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.

    Pulmonary mucormycosis (PM) is a life-threatening opportunistic mycosis with a variable clinical evolution and few prognostic markers for outcome assessment. Several clinical risk factors for poor outcome present at the diagnosis of PM were analyzed in 75 consecutive hematology patients from 2000-2012. Significant variables (P 22 was associated with 8-fold high rates of mortality (P < 0.0001) within 28 days of diagnosis and median survival of 7 days versus ≥28 days in patients with risk scores ≤22. We found that APACHE II score, severe lymphocytopenia and high LDH levels at the time of PM diagnosis were independent markers for rapid disease progression and death.

    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.

    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.

    Full Text Available Purpose. To study the statin influence on lipid exchange and the degree of the brachiocefalic arterys alteration. Methods. The research included 33 high risk patients. The patients inverstigation included lipid spectrum, blood coagulation indexes, by the means of triplex scanning of the brachiochefalic arterys the thickness of the intima - media complex and the expression of stenosis of carotid, vertebral and subclavian arterys were measured. Results. All the patients were divided into the groups according to the total cholesterol and low density lipoprotein cholesterol levels. Patients were divided into subgroups according to the expression of stenosis. The 1 group of patients received rosuvastating 10 mg, the 2 group - atorvastain 20 mg, 3the 3 group - simvastatin 40 mg. This inverstigation shows that the high risk patients with high levels of total cholesterol and low density lipoproteins have the highest expressiveness of brachiocefalic arterys atherosclerosis affection. Conclusion. The assignment of the statins to these patients is accompanied by the lowering of the levels of total cholesterol and low density lipoproteins and the quantity of arteries affected by the atherosclerosis and also by decreasing of the stenosis expression

    Full Text Available Abstract Background Hand-held dynamometry is a portable and inexpensive method to quantify muscle strength. To determine if muscle strength has changed, an examiner must know what part of the difference between a patient's pre-treatment and post-treatment measurements is attributable to real change, and what part is due to measurement error. This study aimed to determine the relative and absolute reliability of intra and inter-observer strength measurements with a hand-held dynamometer (HHD. Methods Two observers performed maximum voluntary peak torque measurements (MVPT for isometric knee extension in 24 patients with haematological malignancies. For each patient, the measurements were carried out on the same day. The main outcome measures were the intraclass correlation coefficient (ICC ± 95%CI, the standard error of measurement (SEM, the smallest detectable difference (SDD, the relative values as % of the grand mean of the SEM and SDD, and the limits of agreement for the intra- and inter-observer '3 repetition average' and the 'highest value of 3 MVPT' knee extension strength measures. Results The intra-observer ICCs were 0.94 for the average of 3 MVPT (95%CI: 0.86–0.97 and 0.86 for the highest value of 3 MVPT (95%CI: 0.71–0.94. The ICCs for the inter-observer measurements were 0.89 for the average of 3 MVPT (95%CI: 0.75–0.95 and 0.77 for the highest value of 3 MVPT (95%CI: 0.54–0.90. The SEMs for the intra-observer measurements were 6.22 Nm (3.98% of the grand mean (GM and 9.83 Nm (5.88% of GM. For the inter-observer measurements, the SEMs were 9.65 Nm (6.65% of GM and 11.41 Nm (6.73% of GM. The SDDs for the generated parameters varied from 17.23 Nm (11.04% of GM to 27.26 Nm (17.09% of GM for intra-observer measurements, and 26.76 Nm (16.77% of GM to 31.62 Nm (18.66% of GM for inter-observer measurements, with similar results for the limits of agreement. Conclusion The results indicate that there is acceptable relative reliability

    Peri-operative management of high-risk paediatric patients undergoing adenotonsillectomy for treatment of obstructive sleep apnoea varies between tertiary referral hospitals. 'Day of surgery cancellation' (DoSC) rates of up to 11% have been reported due to pre-booked critical care being unavailable on the day of surgery as a result of competing needs from other hospital departments. We report the results of a survey of peri-operative management in UK tertiary care centres of high-risk paediatric patients undergoing adenotonsillectomy for obstructive sleep apnoea (OSA). An 8-point questionnaire was developed using a cloud-based software platform (www.surveymonkey.com). A web-link to the survey was embedded in a customised e-mail which was sent via secure server to the Clinical Leads for Paediatric Otolaryngology at 35 United Kingdom (UK) Tertiary referral centres. The survey response rate was 60% (n = 21). Almost all (94.1%) of centres considered paediatric critical care facilities to be limited, with 70.6% (n = 12) stating that DoSC often occurred due to unavailable paediatric critical care capacity. There was variation between tertiary referral units in the practice applied for pre-booking critical care beds (our survey identifies 6 variations) (Table 1). The most frequent selection method reported (47.1%) was at the discretion of the booking clinician at the time of listing the patient for surgery. In the context of limited critical care resources, variation in practice and difficulty in accurately predicting which patients will require post-operative critical care beds, a review and consensus on best practice in the peri-operative management of high risk paediatric adenotonsillectomy patients may offer a safe means of reducing cancellations and improving patient care, resource allocation and hospital efficiency.

    Background Acute erythroid leukaemia (AEL) is a rare subtype of acute myeloid leukaemia (AML), constituting cytogenetic profile of this disease, considering the rarity of its occurrence and poor prognosis. Materials and methods This study was done by retrospective analysis of data from 32 case files of patients diagnosed with AEL. Clinical details noted down were the demographic profile, peripheral blood smear details and bone marrow examination details: (1) blasts-erythroblasts and myeloblasts, (2) dysplasia in the cell lineages and (3) cytogenetic abnormalities. Results The most common presenting symptom was fever. Pancytopenia at presentation was seen in 81.25% of patients. Dysplasia was observed in bone marrow in 100% of erythroblasts and in 40% of myeloblasts in erythroid/myeloid subtype. In pure myeloid subtype, myeloid and megakaryocytic dysplasias were not obvious. Complex karyotype was noticed only in patients of pEL. Conclusion AEL is a rare group of heterogeneous diseases with many neoplastic and non-neoplastic conditions mimicking the diagnosis. The clinical presentation and cytogenetics are also non-specific, presenting additional challenges to the diagnosis. PMID:28144286

    Recent hematology clinical guidelines recommend that palliative care specialists should have central roles in hemato-oncology teams. However, the available research evidence indicates there are presently significant obstacles to the integration of palliative care in hematology. The following discussion presents findings from an Australian study designed to address the problems associated with lack of referral of hematology patients to the palliative system through the development of a best-practice model for end-of-life care for these diagnostic groups. The preliminary step in the development of such a model is to document the factors that denote the special characteristics of the end-of-life stage of hematological conditions and their treatments. This article presents the list of special considerations from a nursing perspective, including issues associated with the high-tech nature of treatments, the speed of change to a terminal event, the need for blood products and possibility of catastrophic bleeds, the therapeutic optimism based on a myriad of treatment options and the clinical indices of the terminal trajectory. The nursing insights provide an important foundation for building a practical, patient-centred model for terminal care in hematology.

    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.

    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.

    Full Text Available Paediatric patients with cancer are a high-risk patient population for medication misadventures. This study aimed to document and evaluate the role of pharmacists’ interventions during dispensing-related activities in minimising the occurrence of medication misadventure in haematology-oncology patients. The primary investigator observed and documented all clinical interventions during dispensing-related activities performed by clinical pharmacists in a haematology-oncology pharmacy during 33-day. A total of 359 interventions were performed for 1028 patients. The rates of intervention were 20.04 per 100 medication orders and 34.92 per 100 patients. Provision of drug information was the most common interventions constituting more than three quarters of all interventions. According to therapeutic groups, cytotoxic antineoplastics made up more than half of all interventions. Of all interventions, 22 involved recommendations leading to changes in patients’ treatment (active interventions, and all recommendations were accepted. The top three medication errors were due to inappropriate dosing, labelling error, and unfulfilled indication. Clinical pharmacists’ intervention during dispensing in a paediatric haematology-oncology pharmacy improved medication safety and patient care by minimising the incidence of medication misadventures.

    Summary Background This paper describes the transmission of hepatitis A virus (HAV) to two blood recipients from a healthy donor that later presented to the blood bank with jaundice. Methods The RNA of HAV was detected by qualitative nested reverse transcription polymerase chain reaction (nested RT-PCR) and quantified by real-time RT-PCR. HAV RNA samples were genotyped by direct sequencing of PCR products. A sequence from a fragment of 168 bp from the VP1/2A HAV region was used to construct a phylogenetic tree. Case Report A 31-year-old male donor accepted for donation of a whole blood unit returned to the blood bank with clinical jaundice 20 days after donation. His serological and NAT tests were negative for HBV and HCV. Serological tests for HAV IgM and IgG were negative on donation sample but positive on follow-up sample, confirming donor's HAV acute infection. Both recipients of red blood cells (R1) and platelet concentrate (R2) from the same implicated donation were HAV IgM-negative and IgG-positive. Qualitative PCR was positive on samples from all three individuals and phylogenetic analysis of viruses proved HAV transmission to the two recipients of blood products. HAV viral load on donor follow-up sample and the platelet recipient was 1.3 and 1.5 × 103 IU/ml, respectively. The RBC recipient, also infected by HCV, was undergoing bone marrow transplantation and died from fulminant hepatitis, 26 days after the implicated HAV transfusion. Conclusion The blood donor, a garbage collector, spontaneously returned to the blood bank when developing jaundice. This highlights the importance of donor education to immediately report to blood banks of any signs and symptoms related to infectious disease developed after blood donation. The fact that one immunocompromised patient with HCV infection died from fulminant hepatitis after receiving a HAV-contaminated platelet transfusion underpins the importance of a HAV vaccination program for these group of patients.

    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

    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

    The first episode of psychosis is a crucial period when early intervention can alter the trajectory of the young person's ongoing mental health and general functioning. After an investigation into completed suicides in the Early Psychosis Prevention and Intervention Centre (EPPIC) programme, the intensive case management subprogramme was developed in 2003 to provide assertive outreach to young people having a first episode of psychosis who are at high risk owing to risk to self or others, disengagement, or suboptimal recovery. We report intensive case management model development, characterise the target cohort, and report on outcomes compared with EPPIC treatment as usual. Inclusion criteria, staff support, referral pathways, clinical review processes, models of engagement and care, and risk management protocols are described. We compared 120 consecutive referrals with 50 EPPIC treatment as usual patients (age 15-24 years) in a naturalistic stratified quasi-experimental real-world design. Key performance indicators of service use plus engagement and suicide attempts were compared between EPPIC treatment as usual and intensive case management, and psychosocial and clinical measures were compared between intensive case management referral and discharge. Referrals were predominately unemployed males with low levels of functioning and educational attainment. They were characterised by a family history of mental illness, migration and early separation, with substantial trauma, history of violence, and forensic attention. Intensive case management improved psychopathology and psychosocial outcomes in high-risk patients and reduced risk ratings, admissions, bed days, and crisis contacts. Characterisation of intensive case management patients validated the clinical research focus and identified a first episode of psychosis high-risk subgroup. In a real-world study, implementation of an intensive case management stream within a well-established first episode of psychosis

    Many randomised trials assessing interferon-α (IFN-α) as adjuvant therapy for high-risk malignant melanoma have been undertaken. To better assess the role of IFN-α, an individual patient data (IPD) meta-analysis of these trials was undertaken. IPD was sought from all randomised trials of adjuvant IFN-α versus no IFN-α for high-risk melanoma. Primary outcomes were event-free survival (EFS) and overall survival (OS). Standard methods for quantitative IPD meta-analysis were used. Subgroup analyses by dose, duration of treatment and various patient and disease-specific parameters were performed. Fifteen trials were included in the analysis (eleven with IPD). EFS was significantly improved with IFN-α (hazard ratio [HR] = 0.86, CI 0.81-0.91; P analysis provides clear evidence that adjuvant IFN-α significantly reduces the risk of relapse and improves survival and shows no benefit for higher doses compared to lower doses. The increased benefit in patients with ulcerated tumours, and lack of benefit in patients without ulceration, needs further investigation. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available 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%, P0.05. 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.

    Full Text Available Abstract Background Artesunate-amodiaquine (AS&AQ is a widely used artemisinin combination therapy (ACT for falciparum malaria. A comprehensive appreciation of its effects on haematology vs other anti-malarials is needed in view of potential safety liabilities. Methods Individual-patient data analysis conducted on a database from seven randomized controlled trials conducted in sub-Saharan African comparing AS&AQ to reference treatments in uncomplicated falciparum malaria patients of all ages. Haematologic values (white cells total and neutrophil counts, haemoglobin/haematocrit, platelets were analysed as both continuous and categorical variables for their occurrence, (severity grade 1-4 and changes during follow-up. Risks and trends were calculated using multivariate logistic random effect models. Results 4,502 patients (72% p = 0.001. Multivariate analysis showed that the risk of anaemia, thrombocytopaenia, and leucopaenia decreased with follow-up time, while neutropaenia increased; the risk of anaemia and thrombocytopaenia increased with higher baseline parasitaemia and parasitological reappearance. White cells total count was not a good surrogate for neutropaenia. No systematic significant difference between treatments was detected. Older patients were at lower risks. Conclusion The effects of AS&AQ on haematologic parameters were not different from those of other anti-malarial treatments used in sub-Saharan Africa. This analysis provides the basis for a broader evaluation of haematology following anti-malarial treatment. Continuing monitoring of haematologic safety on larger databases is required.

    2008-07-01

    To assess the safety and tolerability of ramipril 10 mg in patients at high risk of cardiovascular (CV) events by observing the levels of blood pressure (BP) and by recording the incidence of cough in these patients, a study was conducted in a total of 1048 patients who participated in the registry. Eligible patients in this prospective, observational, longitudinal, multicentre registry included all normotensives--including treated hypertensives--with BP risk reduction and had been prescribed by the treating physician. The primary outcome was the effect on BP at 8 weeks, and the secondary outcome was the incidence of cough at 8 weeks. Ramipril was initiated at 2.5 mg once daily (OD) for a week, followed by 5 mg OD for 3 weeks and was then increased to 10 mg OD. Data was analysed using ANOVA and Chi-square test. A total of 1,048 patients participated in this registry; 868 (82.82%) continued with the treatment till the end of the registry (ie, 8 weeks). At baseline, systolic BP was 130.10 +/- 5.38 mm Hg, while diastolic BP was 81.07 +/- 4.36 mm Hg. At 8 weeks, these values changed non-significantly to 123.41 +/- 6.33 mm Hg and 79.03 +/- 4.84 mm Hg, respectively. At week 1, 41 patients had cough, which increased non-significantly to 58 by week 8. Only 6 patients complained of severe cough at week 8, which did not lead to treatment discontinuation. Tolerability of the treatment was assessed to be 'excellent' or 'good' by 63.3% patients and 67% physicians. Treatment with ramipril 10 mg daily in patients with high risk of CV events and normal/ controlled BP produced neither a significant fall in BP nor significant adverse events in real-world clinical practice and was well tolerated.

    To evaluate the incidence of pharyngocutaneous fistula after pharyngolaryngectomy with and without a Montgomery salivary stent. Retrospective analysis of patients with factors that predispose to the development of pharyngocutaneous fistula (i.e. disease extending to the supraglottic region, base of the tongue or pyriform sinuses, and/or radiochemotherapy). Between 2002 and 2008, 85 pharyngolaryngectomies were performed in our clinic. Of these patients, 31 were at increased risk of fistula development, of whom 45 per cent developed fistulas post-operatively. This subgroup of 31 patients was compared with a second subgroup of 22 patients at high risk of fistula development, treated between 2009 and 2011 with pharyngolaryngectomy and with a Montgomery salivary stent placed in advance during closure of the neopharynx. Statistical analysis showed a significant reduction in the rate of fistula development, from 45 to 9 per cent (p fistula development.

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

    Full Text Available 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 (ScVO 2 , 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.

    Double mobility cup systems (DMCS) have gained increasing acceptance, especially in patients at high risk for dislocation. The aim of this investigation was to analyze the frequency and indications of the DMCS use in our praxis and to evaluate dislocation and cup revision rates after a minimum follow-up of 2 years. All patients implanted with a DMCS from May 2008 to August 2011 were identified from our institutional database of primary and revision THA procedures. Patient demographics, including ASA score, were recorded, along with details of the surgical procedures, indications for DMCS use, and post-operative clinical course and any complications. Radiographs were analyzed for implant positioning and radiological signs of loosening. 1046 primary THA were implanted, of these 39 (4 %) primary DMCS. Indications were severe neuromuscular disease (SND) (14), hip abductor degeneration (HAD) (9), cognitive dysfunction (CD) (8) and others. 345 revision THA were performed, of these 50 (14 %) revision DMCS. Indications were recurrent dislocations (27), multiple prior hip surgeries (13), HAD (5), CD (3) and others. Overall dislocation rate was 2/89 (2 %); both in revision THA. Overall cup revision rate was 5/89 (6 %): 3 septic, 1 periprosthetic acetabular fracture, 1 "intraprosthetic dissociation". 67 patients were available for the standardized questionnaire at a median follow-up of 43 months (range 25-78). 19 patients were not available for two-year follow-up: 17 died and two were lost to follow-up. This study supports the use of DMCS constructs in primary and revision hip arthroplasty for specific high-risk patients. We continue to indicate DMCS in this patient group. We do caution against extending indications for DMCS to lower risk patient groups due to unknown issues surrounding wear and component longevity.

    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 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.

    Full Text Available Abstract Background Cardiopulmonary bypass (CPB with aortic cross-clamping and cardioplegic arrest remains the method of choice for patients requiring standard myocardial revascularization. Therefore, very high-risk patients presenting with acute coronary syndrome, unstable angina, onset of cardiac decompensation and requiring emergency multiple myocardial revascularization, can have a poor outcome. The on-pump beating heart technique can reduce the mortality and the morbidity in such a selected group of patients and this report describes our clinical experience.

    Fungal infections are recognized in an increasing number of patients with immunological deficits and are associated with high rates of mortality (Brown et al., 2012a). In this pilot-study, a rapid Real time PCR (fuPCR) was designed for the detection and differentiation of fungal pathogens in clinical specimens of haematological patients. The fuPCR, targeting the internal transcribed spacer region 2 (ITS2) of rDNA region, is comprised of seven multiplex reactions, which were shown to be specific and sensitive for a comprehensive spectrum of clinically relevant fungal species. This was validated by testing respective fungal DNAs in each fuPCR reaction and 28 respiratory samples of fungal pneumonia-proven patients. Clinical sample sets of throat swab, EDTA-blood and blood sera from 50 patients with severe haematological malignancies, including haematopoietic stem cell transfer (HSCT), and samples from 30 healthy individuals were then analysed. In a first step, 198 samples of immunosuppressed patients were solely examined by fuPCR; and 50.8% (33/65) respiratory swabs, 4.8% (3/63) EDTA blood samples and 1.4% (1/70) blood serum samples were tested positive. In a second step, 56 respiratory samples of immunosuppressed patients and 30 of healthy individuals were simultaneously analysed by fuPCR and standard cultivation techniques. By both methods 30.4% (17/56) swabs of the immunocompromised patients were tested positive, 37.5% (21/56) were tested negative and 32.1% (18/56) were tested fuPCR positive and culture negative. In analysing the blood samples of the immunocompromised patients 5.4% (3/56) EDTA blood samples and 16.1% (9/56) sera samples were tested fuPCR-positive, whereas all samples of 30 healthy individuals with no signs of immunological deficits were tested negative by fuPCR. 38.9% (14/36) of the fungi detected in respiratory samples of the immunosuppressed patients, belonged to Candida spp., 47.2% (17/36) to Saccharomyces spp., 5.6% (2/36) to Cladosporium spp

    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.

    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

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

    Epidemiologic studies have suggested that flavonoid intake plays a critical role in the prevention of coronary heart disease. Because atherosclerosis is considered a low-grade inflammatory disease, some feeding trials have analyzed the effects of cocoa (an important source of flavonoids) on inflammatory biomarkers, but the results have been controversial. The objective was to evaluate the effects of chronic cocoa consumption on cellular and serum biomarkers related to atherosclerosis in high-risk patients. Forty-two high-risk volunteers (19 men and 23 women; mean +/- SD age: 69.7 +/- 11.5 y) were included in a randomized crossover feeding trial. All subjects received 40 g cocoa powder with 500 mL skim milk/d (C+M) or only 500 mL skim milk/d (M) for 4 wk. Before and after each intervention period, cellular and serum inflammatory biomarkers related to atherosclerosis were evaluated. Adherence to the dietary protocol was excellent. No significant changes in the expression of adhesion molecules on T lymphocyte surfaces were found between the C+M and M groups. However, in monocytes, the expression of VLA-4, CD40, and CD36 was significantly lower (P = 0.005, 0.028, and 0.001, respectively) after C+M intake than after M intake. In addition, serum concentrations of the soluble endothelium-derived adhesion molecules P-selectin and intercellular adhesion molecule-1 were significantly lower (both P = 0.007) after C+M intake than after M intake. These results suggest that the intake of cocoa polyphenols may modulate inflammatory mediators in patients at high risk of cardiovascular disease. These antiinflammatory effects may contribute to the overall benefits of cocoa consumption against atherosclerosis. This trial was registered in the Current Controlled Trials at London, International Standard Randomized Controlled Trial Number, at controlled-trials.com as ISRCTN75176807.

    Our purpose was to compile information on the haematological manifestations of systemic lupus erythematosus (SLE), namely leucopenia, lymphopenia, thrombocytopenia, autoimmune haemolytic anaemia (AIHA), thrombotic thrombocytopenic purpura (TTP) and myelofibrosis. During our search of the English-language MEDLINE sources, we did not place a date-of-publication constraint. Hence, we have reviewed previous as well as most recent studies with the subject heading SLE in combination with each manifestation. Neutropenia can lead to morbidity and mortality from increased susceptibility to infection. Severe neutropenia can be successfully treated with granulocyte colony-stimulating factor. While related to disease activity, there is no specific therapy for lymphopenia. Severe lymphopenia may require the use of prophylactic therapy to prevent select opportunistic infections. Isolated idiopathic thrombocytopenic purpura maybe the first manifestation of SLE by months or even years. Some manifestations of lupus occur more frequently in association with low platelet count in these patients, for example, neuropsychiatric manifestation, haemolytic anaemia, the antiphospholipid syndrome and renal disease.

    Our purpose was to compile information on the haematological manifestations of systemic lupus erythematosus (SLE), namely leucopenia, lymphopenia, thrombocytopenia, autoimmune haemolytic anaemia (AIHA), thrombotic thrombocytopenic purpura (TTP) and myelofibrosis. During our search of the English-language MEDLINE sources, we did not place a date-of-publication constraint. Hence, we have reviewed previous as well as most recent studies with the subject heading SLE in combination with each manifestation. Neutropenia can lead to morbidity and mortality from increased susceptibility to infection. Severe neutropenia can be successfully treated with granulocyte colony-stimulating factor. While related to disease activity, there is no specific therapy for lymphopenia. Severe lymphopenia may require the use of prophylactic therapy to prevent select opportunistic infections. Isolated idiopathic thrombocytopenic purpura maybe the first manifestation of SLE by months or even years. Some manifestations of lupus occur more frequently in association with low platelet count in these patients, for example, neuropsychiatric manifestation, haemolytic anaemia, the antiphospholipid syndrome and renal disease. Thrombocytopenia can be regarded as an important prognostic indicator of survival in patients with SLE. Medical, surgical and biological treatment modalities are reviewed for this manifestation. First-line therapy remains glucocorticoids. Through our review, we conclude glucocorticoids do produce a response in majority of patients initially, but sustained response to therapy is unlikely.

    Adverse reactions to iodinated contrast media (CM) may occur and require prompt recognition and treatment. Although adverse reactions to radiocontrast agents cannot be eliminated, an important first step toward reducing their incidence is to identify patients at greatest risk. Prior to examinations using CM, patients should be adequately assessed by obtaining thorough medical histories and using simple screening tests. Studies have demonstrated that patients with a history of asthma, allergy, hyperthyroidism, and previous reaction to CM are at risk for severe reactions to iodinated CM. Renal adverse reactions reportedly occur more frequently in patients with pre-existing chronic kidney disease, especially those with diabetic nephropathy. Patients with congestive heart failure, dehydration, older age, and those who use nephrotoxic medications are also at risk for developing contrast-associated nephropathy. The occurrence of adverse events may be further increased in patients with multiple risk factors. As the number of patients undergoing computed tomography procedures continues to increase, it is essential for physicians to be able to identify patients at risk for adverse events of CM. Patient-related risk factors are discussed and simple tools for risk stratification presented.

  4. The "T-MIDCAB" procedure. Use of extension grafts from the undisturbed internal mammary artery in high-risk patients.

    Minimally invasive direct coronary artery bypass grafting (MIDCAB) is an attractive new alternative for revascularizing patients with high perioperative risk for standard coronary surgery. However, limited surgical exposure through a small thoracotomy makes harvesting the full length of the internal mammary artery (IMA) very difficult and time consuming. We are now employing a new alternative with a "T" shaped bridge graft constructed from the undisturbed IMA using a 4 centimeter interposition segment of donor vessel. We prefer this approach in high risk cases in order to reduce the trauma of the thoracotomy, minimize pain and narcotic use, promote early extubation, and achieve immediate post-operative mobilization and recovery in patients who would otherwise be at risk for a poor outcome with conventional grafting techniques. From September 10, 1997 to December 19, 1997 eight high-risk patients underwent at least one "T-MIDCAB" graft from the undisturbed IMA to the coronary artery using a short segment of either radial artery or saphenous vein. All cases were performed using a limited access anterior thoracotomy through the bed of the resected costal cartilage and without intercostal retraction. Five males and three females ranging from 58 to 83 years (average 73 years) were operated using this new concept. Pre-operative ejection fractions ranged from 25% to 80% (mean 43%). Parsonnet scores ranged from 21 to 43 (average 34) with predicted mortalities ranging from 30 to 40%. Eleven "T" grafts were placed (1.38 distals/patient). All 8 patients survived. Postoperative complications were minimal. The average length of stay was only 8 days (range 3 to 9 days). Intensive care unit stay averaged 3 days (range 1 to 4 days). One patient underwent postoperative angiography which demonstrated full patency of the conduit and all anastomoses. "T-MIDCAB" using a bridge graft of free radial artery or saphenous vein appears to be successful in high risk patients. The authors

    We evaluated the efficacy and safety of amlodipine besylate alone or in combination with other antihypertensive agents in high-risk hypertensive patients in Spanish primary care. In this 1-year, open-label, prospective cohort study, 7468 patients were treated with amlodipine 5 - 10 mg as a monotherapy or as an add-on therapy to attain blood pressure control (target of risk) was -8.6%, down from 24.7% at baseline (relative risk reduction, 31.6%). Change in blood pressure from baseline (162.5/95.3 mmHg) was -26.7/-14.6 mmHg, and 38.6% of patients achieved their blood pressure target. In summary, significant reductions in predicted coronary heart disease risk and blood pressure were observed with amlodipine both as a monotherapy and as an add-on therapy. Amlodipine was well tolerated and compliance with treatment was good.

    In an era of increasingly shortened admissions, data regarding predictors of early rebleeding among patients with nonvariceal upper gastrointestinal bleeding (NVUGIB) exhibiting high-risk stigmata (HRS) having undergone endoscopic hemostasis are lacking. To determine predictors of early rebleeding, defined as rebleeding before completion of recommended 72 h intravenous proton pump inhibitor infusion postendoscopic hemostasis. Data from a national registry of patients with upper gastrointestinal bleeding (the REASON registry) were accessed. Univariable and multivariable analyses were sequentially performed to identify significant independent predictors among a comprehensive list of clinical and laboratory characteristics. Overall, 393 patients underwent endoscopic hemostasis for NVUGIB with HRS. Forty patients rebled ≤72 h thereafter (32.5% female, mean [± SD] age 70.2 ± 11.8 years, 2.88 ± 2.11 comorbidities), while 21 rebled later (38.1% female, mean 70.5 ± 14.1 years of age, 2.62 ± 2.06 comorbidities). Hematemesis or bright red blood per nasogastric tube aspirate was identified as the sole independent significant predictor of early rebleeding versus later among both NVUGIB and, more specifically, patients with peptic ulcer bleeding (OR 7.94 [95% CI 1.80 to 35.01]; P<0.01, and OR 8.41 [95% CI 1.54 to 46.10]; P=0.014, respectively). When attempting to determine the optimal duration of pharmacotherapy and timing of discharge for patients following endoscopic hemostasis for NVUGIB with HRS, it is noteworthy that individuals who present with hematemesis or bright red blood per nasogastric tube aspirate are at particularly high risk for rebleeding within the first 72 h.

    The "credit card" asthma self-management plan provides the adult asthmatic patient with simple guidelines for the self-management of asthma, which are based on the self-assessment of peak expiratory flow rate recordings and symptoms. The study was a trial of the clinical efficacy of the credit card plan in a high-risk group of asthmatic patients. In this "before-and-after" trial, patients discharged from the emergency department of Wellington Hospital, after treatment for severe asthma were invited to attend a series of hospital outpatient clinics at which the credit card plan was introduced. Questionnaires were used to compare markers of asthma morbidity, requirement for emergency medical care, and medication use during the 6-month period before and after intervention with the credit card plan. Of the 30 patients with asthma who attended the first outpatient clinic, 26 (17 women and 9 men) completed the program. In these 26 participants, there was a reduction in both morbidity and requirement for acute medical services: specifically, the proportion waking with asthma more than once a week decreased from 65% to 23% (p = 0.005) and the proportion visiting the emergency department for treatment of severe asthma decreased from 58% to 15% (p = 0.004). The patients attending the clinics commented favorably on the plan, in particular on its usefulness as an educational tool for monitoring and treating their asthma. Although the interpretation of this study is limited by the lack of a randomized control group, the findings are consistent with other evidence that the credit card asthma self-management plan can be an effective and acceptable system for improving asthma care in a high-risk group of adult patients with asthma.

    Postoperative cerebrospinal fluid (CSF) leak in neurosurgery remains a significant source of morbidity. TissuePatchDural (TPD), a novel impermeable adhesive membrane, can be used to reinforce dural closure in cases considered at high risk to develop postoperative CSF leak. A retrospective, single-center, clinical investigation was conducted on 119 patients who underwent elective neurosurgical procedures between January and June 2010. Inclusion criteria included adult patients undergoing clean elective surgeries where a primary watertight closure was not possible. Three groups of patients were considered: 1) infratentorial, 67 cases; 2) supratentorial, 34 cases; and 3) spinal, 18 cases. All these patients received TPD to reinforce dural closure. Preoperative (long-term corticosteroid therapy, previous surgery and radiotherapy), intraoperative (site of procedures and size of dural gap), and postoperative (early and late hydrocephalus) conditions were analyzed as possible risk factors associated with CSF leakage. The mean follow-up was 7.14 months (range 6-12 months). CSF leak was detected in 11 of 119 cases (9.2%). The presence of pre- and postoperative risk factors was associated with a higher percentage of CSF leakage: 8 of 22 cases (36.3%) vs. 3 of 97 cases (3.1%) (P < 0.0001). All leaks could be conservatively treated and no patient required readmission or second surgery. No TPD-related adverse or allergic effects were observed. TPD seems to be a safe tool to be used to reinforce dural closure in patients with a high risk of developing CSF leaks. Copyright © 2013 Elsevier Inc. All rights reserved.

    The benefit of administering beta-adrenergic blocking agents perioperatively to surgical patients at high risk for myocardial ischemia has been demonstrated in several well-designed randomized controlled trials. These benefits have included a reduction in the incidence of myocardial complications and an improvement in overall survival for patients with evidence of or at risk for coronary artery disease (CAD). We designed a retrospective study at the Ottawa Civic Hospital to investigate the use of beta-blockers in the perioperative period for high-risk general surgery patients who underwent laparotomy and to explore the reasons for failure to prescribe or administer beta-blockers when indicated. All 236 general surgery patients over the age of 50 years who underwent laparotomy for major gastrointestinal surgery between Jan. 1, 2001, and Dec. 31, 2001, were assigned a cardiac risk classification using the risk stratification described by Mangano and colleagues. The perioperative prescription and administration of beta-blockers were noted as were the patient's heart rate and blood pressure parameters for the first postoperative week, in-hospital adverse cardiac events and death. Of the 143 patients classified as being at risk for CAD or having definite evidence of CAD, 87 (60.8%) did not receive beta-blockers perioperatively. Of those who did, 43 were previously on beta-blockers and 13 had them ordered preoperatively. Patients with definite CAD were significantly more likely than others to receive beta-blockers perioperatively (p nurses irrespective of nil par os status. The mean heart rate and blood pressure parameters for patients receiving beta-blockers postoperatively was 82 beats/min and 110 mm Hg, respectively, and these values were not significantly different from the mean heart rate of patients not receiving beta-blockers. The number of postoperative cardiac events was significantly higher in patients with definite evidence of CAD, and among this group, the

    AIM To study the change of trace elements in the hair of patients with esophageal carcinoma and the role oftrace elements in its development and progress.METHODS The hair of 60 normal people and 126 patients was collected and was divided into groupsaccording to the patients' pathologic changes. The atomic absorption method and fluorescence method wereused to measure the trace elements of copper, zinc, iron, calcium and selenium.RESULTS Zinc in the hair of various patients: a remarkable difference was found between normal people(182mg· kg 1)and the patients (103- 81.6mg·kg 1) (t = 3.79, P0.05). The ratio of zinc to copper increased with thedevelopment of pathologic change. The selenium levels in patients (0.46-0.67mg·kg-1) was below that ofnormal people (l.03mg·kg-1), while iron and calcium levels in the patients decreased with the developmentof pathologic process.CONCLUSION Both zinc and copper play an important role in the pathologic change of esophagealcarcinoma. Zinc and copper in the hair changed with development of the pathologic process. Zinc revealedpositive correlation ( r = -0. 889, P < 0.01 while copper showed negative correlation ( r = 0.921, P < 0.01 ).The ratio of copper to zinc in the hair is of great diagnostic value.

    To analyse intensity of treatment of high-risk patients with non-ST elevation acute coronary syndromes (NSTEACS) included in the DESCARTES (Descripción del Estado de los Sindromes Coronarios Agudos en un Registro Temporal Español) registry. Patients with NSTEACS (n = 1877) admitted to 45 randomly selected Spanish hospitals in April and May 2002 were studied. Patients with ST segment depression and troponin rise were considered high risk (n = 478) and were compared with non-high risk patients (n = 1399). 46.9% of high-risk patients versus 39.5% of non-high-risk patients underwent angiography (p = 0.005), 23.2% versus 18.8% (p = 0.038) underwent percutaneous revascularisation, and 24.9% versus 7.4% (p or = 4, 2-3 and or = 4 (OR 2.87, 95% CI 1.27 to 6.52, p = 0.012). Class I recommended treatments were underused in high-risk patients in the DESCARTES registry. This undertreatment was an independent predictor of death of patients with an acute coronary syndrome.

    Many individuals with diabetes remain undiagnosed, leading to delays in treatment and higher risk for subsequent diabetes complications. Despite recommendations for diabetes screening in high risk groups, the optimal approach is not known. We evaluated the utility of inpatient glucose levels as an opportunistic screening tool for identifying patients at high risk for diabetes. We retrospectively examined 462,421 patients in the national VA healthcare system, hospitalized on medical/surgical services in 2000-2010, for ≥3 days, with ≥2 inpatient random plasma glucose (RPG) measurements. All had continuity of care - ≥1 primary care visit and ≥1 glucose measure within 2 years before hospitalization and yearly for ≥3 years after discharge. Glucose levels during hospitalization and incidence of diabetes within 3 years after discharge in patients without diabetes were evaluated. Patients had mean age 65.0 years, BMI 29.9, and were 96% male, 71% white, and 18% black. Preexisting diabetes was present in 39.4%, 1.3% were diagnosed during hospitalization, 8.1% diagnosed RPG (112 mg/dl [6.2 mmol/L]). Having at least two RPGs >140 mg/dl (>7.8 mmol/L), the 95(th) percentile of NonDM hospital glucose, provided 81% specificity for identifying incident diabetes <3 years post-discharge. Screening for diabetes could be considered in patients with at least two hospital glucoses at/above the 95th percentile of the nondiabetic range (141 mg/dl [7.8 mmol/L]). Copyright © 2017.

  2. Old age, high risk medication, polypharmacy: a ‘trilogy’ of risks in older patients with atrial fibrillation

    Science.gov (United States)

    2015-01-01

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

    To retrospectively evaluate the efficacy and safety of percutaneous radiofrequency ablation (RFA) done to treat renal tumors in patients with high surgical risk or with the risk of developing multiple renal tumors in the medium term at our center over a period of 10 years. Between 2005 and 2015, we used RFA to treat 89 T1a or T1b tumors in 87 patients (mean age, 73.7±10.87 years) with high surgical risk. We excluded patients treated with radiofrequency and embolization or microwave ablation. The tumors treated were clear cell carcinomas (43.6%), papillary renal carcinomas (17.2%), chromophobe renal cell carcinomas (10.3%), cystic tumors (2.2%), and an angiomyolipoma (1.1%). The mean size of the tumors was 2.6cm. Computed tomography and/or ultrasonography were used to guide the procedure. We analyzed the relation between the efficacy of the procedure and patients' age, the type of needle, the source of the patients, the size and location of the tumor, and the number of sessions required to achieve ablation. We recorded all complications. The RFA procedure was completed in all patients. The mean follow-up period was 32.1 months. The efficacy was 93.7%. A single session was sufficient in 87.5% of patients; 8% required two sessions and 4.5% required three sessions. The only factor associated with worse efficacy was the size of the tumor (p=0.03). The rate of complications was 5.6%. RFA is efficacious and safe, with results comparable to those reported in the literature. Copyright © 2016 SERAM. Publicado por Elsevier España, S.L.U.

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

    The aim of the study was to analyse the influence of prevention measures on pressure injuries for high-risk patients and to establish the most appropriate methods of implementation. Nurses assessed patients using a checklist and factors influencing the prevention of a pressure injury determined by brain storming. A specific series of measures was drawn up and an estimate of risk of pressure injury determined using the Braden Scale, analysis of nursing documents, implementation of prevention measures for pressure sores and awareness of the system both before and after carrying out a quality control circle (QCC) process. The overall scores of implementation of prevention measures ranged from 74.86 ± 14.24 to 87.06 ± 17.04, a result that was statistically significant (P control. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    Combination therapy with benazepril 40 mg and amlodipine 10 mg (B+A) has been shown to be more effective than benazepril 40 mg and hydrochlorothiazide (HCTZ) 25 mg (B+H) in reducing cardiovascular (CV) events in high-risk patients with stage 2 hypertension with similar blood pressure reductions. In the present post hoc analysis, we evaluated whether B+A is more effective than B+H for reducing CV events in patients with known coronary artery disease (CAD) at baseline in a subgroup analysis of the Avoiding Cardiovascular events through COMbination therapy in Patients LIving with Systolic Hypertension (ACCOMPLISH) study. The main trial randomized 11,506 patients. Of those, 5,744 received B+A and 5,762 received B+H. Of the 11,506 patients, 5,314 (46%) were classified as having CAD at baseline. The mean patient follow-up period was 35.7 months for the B+A group and 35.6 months for the B+H group. The primary end point was the interval to the first event of composite CV morbidity and mortality. At baseline, significant differences were present between the 5,314 with CAD and the 6,192 without CAD. The patients with CAD had a lower systolic blood pressure and heart rate, a lower incidence of diabetes, and greater incidence of dyslipidemia. However, no baseline differences were found between the randomized B+A and B+H groups. In the patients with CAD, an 18% reduction occurred in the hazard ratio for CV events (primary end point) with B+A versus B+H (p = 0.0016). In a prespecified secondary analysis of the composite end point, including only CV death, myocardial infarction, and stroke, the hazard ratio in the patients with CAD was reduced by 25% (p = 0.0033) in the B+A group compared with the B+H group. B+A was more effective than B+H at comparable blood pressure reductions for reducing CV events in patients, regardless of the presence of CAD. In conclusion, our findings suggest that the combination of B+A should be preferentially used for older patients with high-risk

Methods: A retro prospective study was done in western Rajasthan on PUO patients those who attended Hospital attached of Dr. SNMC Jodhpur. Total 570 samples were tested for Brucella antibodies titration. In study group samples of PUO Patients (420, Milkmen & Veterinarians (70, Meat Handlers (30 & Healthy Control (50 were taken for finding their Antibrucella antibody titers Typhoid by Widal Test, Malaria by MP Strip Test were included in exclusion criteria for PUO patients All samples were tested by Stained Febrile Antigen. Results: Positivity for Antibrucella Antibody was 25.72%, 26.66%, 37.14%& 6.00% in PUO Patients, Meat Handlers & Veterinarians, Milkman & Healthy Control respectively. Conclusion & Recommendations: As climatic conditions of Western Rajasthan mimics with Middle East where Brucellosis is prevalent, in clinical practice Brucellosis should be kept in differential diagnosis & management of PUO& all preventive measure should be used for prevention of this Zoonotic disease.. A safe and effective vaccine in human is not yet available. Prevention is dependent upon increasing public awareness through health education programmes and safe livestock practices. Active co-operation between health and veterinary services should be promoted.

    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 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

    Bococizumab is a humanized monoclonal antibody that inhibits proprotein convertase subtilisin-kexin type 9 (PCSK9) and reduces levels of low-density lipoprotein (LDL) cholesterol. We sought to evaluate the efficacy of bococizumab in patients at high cardiovascular risk. In two parallel, multinational trials with different entry criteria for LDL cholesterol levels, we randomly assigned the 27,438 patients in the combined trials to receive bococizumab (at a dose of 150 mg) subcutaneously every 2 weeks or placebo. The primary end point was nonfatal myocardial infarction, nonfatal stroke, hospitalization for unstable angina requiring urgent revascularization, or cardiovascular death; 93% of the patients were receiving statin therapy at baseline. The trials were stopped early after the sponsor elected to discontinue the development of bococizumab owing in part to the development of high rates of antidrug antibodies, as seen in data from other studies in the program. The median follow-up was 10 months. At 14 weeks, patients in the combined trials had a mean change from baseline in LDL cholesterol levels of -56.0% in the bococizumab group and +2.9% in the placebo group, for a between-group difference of -59.0 percentage points (P<0.001) and a median reduction from baseline of 64.2% (P<0.001). In the lower-risk, shorter-duration trial (in which the patients had a baseline LDL cholesterol level of ≥70 mg per deciliter [1.8 mmol per liter] and the median follow-up was 7 months), major cardiovascular events occurred in 173 patients each in the bococizumab group and the placebo group (hazard ratio, 0.99; 95% confidence interval [CI], 0.80 to 1.22; P=0.94). In the higher-risk, longer-duration trial (in which the patients had a baseline LDL cholesterol level of ≥100 mg per deciliter [2.6 mmol per liter] and the median follow-up was 12 months), major cardiovascular events occurred in 179 and 224 patients, respectively (hazard ratio, 0.79; 95% CI, 0.65 to 0.97; P=0.02).

    Myeloablative allogeneic haematopoietic stem cell transplantation (allo-HSCT) is a major procedure usually accompanied by multifactorial malnutrition, prompting the recommendation of systematic artificial nutritional support. Parenteral nutrition (PN) is usually administered during allo-HSCT, essentially for practical reasons. Recently published data suggest that enteral nutrition (EN), given as systematic artificial nutrition support, could decrease grade III-IV graft-versus-host disease (GVHD) and infectious events, which are associated with early toxicity after allo-HSCT and then have an impact on early transplant-related mortality (D100 mortality). We report on the NEPHA trial: an open-label, prospective, randomised, multi-centre study on two parallel groups, which has been designed to evaluate the effect of EN compared to PN on early toxicity after an allo-HSCT procedure. Two hundred forty patients treated with allo-HSCT for a haematological malignancy will be randomly assigned to two groups to receive either EN or PN. The primary endpoint will assess the effect of EN on D100 mortality. Secondary endpoints will compare EN and PN with regards to the main haematological, infectious and nutritional outcomes. The impacts of nutritional support should exceed the limits of nutritional status improvement: EN may directly reduce immunological and infectious events, as well as decrease early transplant-related morbidity and mortality. EN and PN need to be prospectively compared in order to assess their impacts and to provide treatment guidelines. (Clinical trials gov number: NCT01955772; registration: July 19th, 2013).

    Full Text Available Early goal-directed therapy is a term used to describe the guidance of intravenous fluid and vasopressor/inotropic therapy by using cardiac output or similar parameters in the immediate post-cardiopulmonary bypass in cardiac surgery patients. Early recognition and therapy during this period may result in better outcome. In keeping with this aim in the cardiac surgery patients, we conducted the present study. The study included 30 patients of both sexes, with EuroSCORE ≥3 undergoing coronary artery bypass surgery under cardiopulmonary bypass. The patients were randomly divided into two groups, namely, control and early goal-directed therapy (EGDT groups. All the subjects received standardized care; arterial pressure was monitored through radial artery, central venous pressure through a triple lumen in the right internal jugular vein, electrocardiogram, oxygen saturation, temperature, urine output per hour and frequent arterial blood gas analysis. In addition, cardiac index monitoring using FloTrac™ and continuous central venous oxygen saturation using PreSep™ was used in patients in the EGTD group. Our aim was to maintain the cardiac index at 2.5-4.2 l/min/m 2 , stroke volume index 30-65 ml/beat/m 2 , systemic vascular resistance index 1500-2500 dynes/s/cm 5 /m 2 , oxygen delivery index 450-600 ml/min/m 2 , continuous central venous oximetry more than 70%, stroke volume variation less than 10%; in addition to the control group parameters such as central venous pressure 6-8 mmHg, mean arterial pressure 90-105 mmHg, normal arterial blood gas analysis values, pulse oximetry, hematocrit value above 30% and urine output more than 1 ml/kg/h. The aims were achieved by altering the administration of intravenous fluids and doses of inotropic or vasodilator agents.

    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. 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. 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.

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

    OBJECTIVE To explore molecular markers for cervical cancer in female patients below thirty-five years of age, so that the markers may be used to formulate a prognosis and to provide some useful targets for improving therapy.METHODS Pathological data were collected from 64 cervical cancer patients under the age of 35 from June, 1995 to June, 2000 in our institution.The data were retrospectively analyzed as a study group, and compared to data obtained from 90 cervical cancer cases over the age of 35 as controls who underwent treatment during the same time period. Immunohistochemical and quantified image analyses were conducted to look for differences between the two groups in expression of survivin, p27,CD44v6, MMP-2 and TIMP-2.RESULTS The overall 5-year survival rate (65.6%) of the study group was significantly lower (P<0.05) compared to the control group (84.4%). The expression of survivin, MMP-2 and CD44v6 was much higher in the younger study group compared to the older control group, but TIMP-2 displayed higher expression in the control group (P<0.05). There was no significant difference in p27 expression between the two groups (P>0.05).CONCLUSION Young women patients with cervical cancer have a poorer prognosis compared to old women. Our study reveals that survivin,MMP-2, TIMP-2 and CD44v6 expression have a correlation with shorter 5-year survival. Improvement in the prognosis for young cervical cancer patients can be expected using biomedical therapy which targets these molecular markers.

    Full Text Available Background. Cardiac troponin levels have been reported to add value in the detection of cardiovascular complications in noncardiac surgery. A sensitive cardiac troponin I (cTnI assay could provide more accurate prognostic information. Methods. This study prospectively enrolled 142 patients with at least one Revised Cardiac Risk Index risk factor who underwent noncardiac surgery. cTnI levels were measured postoperatively. Short-term cardiac outcome predictors were evaluated. Results. cTnI elevation was observed in 47 patients, among whom 14 were diagnosed as having myocardial infarction (MI. After 30 days, 16 patients had major adverse cardiac events (MACE. Excluding patients with a final diagnosis of MI, predictors of cTnI elevation included dialysis, history of heart failure, transoperative major bleeding, and elevated levels of pre- and postoperative N-terminal pro-B-type natriuretic peptide (NT-proBNP. Maximal cTnI values showed the highest sensitivity (94%, specificity (75%, and overall accuracy (AUC 0.89; 95% CI 0.80–0.98 for postoperative MACE. Postoperative cTnI peak level (OR 9.4; 95% CI 2.3–39.2 and a preoperative NT-proBNP level ≥917 pg/mL (OR 3.47; 95% CI 1.05–11.6 were independent risk factors for MACE. Conclusions. cTnI was shown to be an independent prognostic factor for cardiac outcomes and should be considered as a component of perioperative risk assessment.

    The paper examined the quality of life of haematological cancer patients according to their socio-demographic profiles and clinical diagnoses. This cross-sectional study was conducted at the tertiary referral centre of Ampang Hospital, Kuala Lumpur, involving 105 patients. The European Organisation for Research and Treatment of Cancer Quality of Life (EORTC QLQ-C30) questionnaire was used to measure their quality of life. The study involved patients diagnosed with all types of haematological cancer, including non-Hodgkin lymphoma (NHL), acute myelogenous leukaemia (AML), acute lymphoblastic leukaemia (ALL), Hodgkin lymphoma (HL), and multiple myeloma (MM), with a response rate of 83.3%. The patients with ALL, HL, without NHL, and without MM were younger than other patients. There were significant differences in quality of life scores in different socio-demographic groups and types of cancer diagnosis. The global quality of life of the female patients was much better than that of the male patients. Patients who were 40 years old or younger had a better global quality of life and physical functioning, as well as fewer symptoms of constipation, nausea, and vomiting. Employed patients were in less pain but showed greater impairments of cognitive function than did unemployed patients. Patients who earned a monthly wage of RM1000 or less had reduced physical function, more symptoms of pain, and more financial difficulties compared with patients who earned more. Patients with AML tended to have better physical functioning than did patients with MM, whose physical functioning was impaired. Comparatively, more symptoms of dyspnoea were found in ALL and HL patients than in other types of lymphoma. Compared with other patients, those with ALL had a greater loss of appetite, and other lymphoma patients had fewer symptoms of pain. Patients with NHL had impaired role functioning and more constipation compared with other patients. The results were all statistically significant (P

    Evaluation of predictors of silent coronary artery disease (SCAD) in high-risk asymptomatic diabetic patients and to evaluate their two-year outcome. Four hundred diabetic patients without prior CAD but at high CAD risk underwent myocardial perfusion scintigraphy (MPS) in this prospective multicentre outcome trial. MPS were abnormal in 22% of patients. Male sex (OR 2.223, 1.152-4.290; p=0.017), diabetes duration (OR 1.049,1.015-1.085; p=0·005), peripheral artery disease (OR 2.134, 1·150-3.961; p=0.016), smoking (OR 2.064, 1.109-3.839; p=0·022), systolic blood pressure (OR 1.014, 1.00-1.03, p=0·056), brain natriuretic peptide (OR 1.002, 1.001-1.004, p=0·005) independently predicted an abnormal MPS: if 3 predictors were present, 3.2% and 47% patients had an abnormal MPS, respectively (p10%, respectively (each p3 predictors, almost 50% of patients had an abnormal MPS. They may benefit from screening by MPS since the extent of the MPS abnormality discriminated clearly between a favourable compared to a bad 2-year outcome. However, even highest risk patients without objective evidence of CAD had a benign prognosis without need for specific evaluation or therapy. ISRCTN87953632. Copyright © 2017 The Authors.

    Full Text Available MitraClip system implantation is used inhigh-risk patients with severe mitral regurgitation.anesthetic management for mitral clip implantation. The study included 34patients scheduled for MitraClip implantations in the catheterization laboratory. An arterial line and central venous line were inserted under local anesthesia before induction. Epinephrine was started before induction and milrinone infusion was started after induction. The anesthetic technique for induction and maintenance was the same for all patients. All patients were hemodynamically stable intra- and postoperatively. The intervention was successful in 33 cases and aborted in one case because of severe posteromedial leaflet tethering. The epinephrine and milrinone were weaned and all patients were extubated, except, one case mortality happened within the first 8 hours postoperatively. Percutaneous mitral valve repair with MitraClip implantation is a successful alternative in high-risk patients with symptomatic severe mitral regurgitation. Starting epinephrine before anesthetic induction and milrinone infusion induction resulted in decreased pulmonary artery pressure, increased ejection fraction and maintained arterial blood pressure during procedure inspite of worse preoperative conditions.

    Rapid detection of candidaemia is crucial for timely antifungal chemotherapy. However, the sensitivity of automated blood culture (BC) systems has been questioned. Blind subculture might increase detection rate and possibly also reduce time to detection of candidaemia. This retrospective study aimed to evaluate the efficacy of blind subcultures in patients deemed at high risk of candidaemia. BCs were processed by the BacT/Alert BC system, and during a 5-y period (1998-2003) subculture on the third d of incubation was performed for patients selected by clinical and microbiological assessment. A total of 79,165 BCs were drawn during the study period. 2154 BCs from 285 patients were selected for subculture. 103 (4.8%) BCs from 52 patients were yeast positive; 71 were detected positive prior to the planned subculture, 25 were positive on subculture, and 7 were negative on subculture, but became positive during further incubation. The 25 BCs positive on subculture originated from 14 patients, 11 of whom had already been diagnosed with candidaemia during the previous 14 d. Thus, a primary diagnosis of candidaemia was obtained by subculture in only 3 (1.1%) of the 285 patients selected. In conclusion, in our clinical setting blind subculture did not materially increase the detection of candidaemia, but helped to document persistent infection in a subset of cases.

    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.

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

    The hemoglobin threshold at which postoperative red-cell transfusion is warranted is controversial. We conducted a randomized trial to determine whether a higher threshold for blood transfusion would improve recovery in patients who had undergone surgery for hip fracture. We enrolled 2016 patients who were 50 years of age or older, who had either a history of or risk factors for cardiovascular disease, and whose hemoglobin level was below 10 g per deciliter after hip-fracture surgery. We randomly assigned patients to a liberal transfusion strategy (a hemoglobin threshold of 10 g per deciliter) or a restrictive transfusion strategy (symptoms of anemia or at physician discretion for a hemoglobin level of <8 g per deciliter). The primary outcome was death or an inability to walk across a room without human assistance on 60-day follow-up. A median of 2 units of red cells were transfused in the liberal-strategy group and none in the restrictive-strategy group. The rates of the primary outcome were 35.2% in the liberal-strategy group and 34.7% in the restrictive-strategy group (odds ratio in the liberal-strategy group, 1.01; 95% confidence interval [CI], 0.84 to 1.22), for an absolute risk difference of 0.5 percentage points (95% CI, -3.7 to 4.7). The rates of in-hospital acute coronary syndrome or death were 4.3% and 5.2%, respectively (absolute risk difference, -0.9%; 99% CI, -3.3 to 1.6), and rates of death on 60-day follow-up were 7.6% and 6.6%, respectively (absolute risk difference, 1.0%; 99% CI, -1.9 to 4.0). The rates of other complications were similar in the two groups. A liberal transfusion strategy, as compared with a restrictive strategy, did not reduce rates of death or inability to walk independently on 60-day follow-up or reduce in-hospital morbidity in elderly patients at high cardiovascular risk.

    2014-01-01

    Full Text Available Nitric oxide (NO is a selective pulmonary vasodilator especially in the presence of pulmonary artery hypertension. With right ventricle (RV dysfunction, inhaled NO may increase RV ejection fraction and cardiac output. The main advantage of NO over intravenous therapy is its inability to decrease systemic pressure thereby maintaining the coronary perfusion pressure and the myocardial perfusion. In this case report, we discuss the use of NO in a routine thoracic surgery patient suffering with severe left ventricular dysfunction and a potential candidate for a very high cardiac risk.

    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

    Dark chocolate may have blood pressure-lowering properties. We conducted a prospective randomized open-label blinded end-point design trial to study a potential dose dependency of the presumed antihypertensive effect of dark chocolate by directly comparing low vs. higher doses of dark chocolate over the course of 3 months. We enrolled a total of 102 patients with prehypertension/stage 1 hypertension and established cardiovascular end-organ damage or diabetes mellitus. Patients were randomly assigned to receive either 6 or 25 g/day of flavanol-rich dark chocolate for 3 months. The difference in 24-h mean blood pressure between groups was defined as the primary outcome measure. Significant reductions in mean ambulatory 24-h blood pressure were observed between baseline and follow-up in both groups (6 g/day: -2.3 mm Hg, 95% confidence interval -4.1 to -0.4; 25 g/day: -1.9 mm Hg, 95% confidence interval -3.6 to -0.2). There were no significant differences in blood pressure changes between groups. In the higher-dose group, a slight increase in body weight was noted (0.8 kg, 95% confidence interval 0.06 to 1.6). The findings are consistent with the hypothesis that dark chocolate may be associated with a reduction in blood pressure (BP). However, due to the lack of a control group, confounding may be possible and the results should be interpreted with caution.

    The four major factors predisposing individuals to community-acquired pneumonia (CAP) are chronic obstructive pulmonary disease, congestive heart failure, diabetes, and a high alcohol intake. The elderly are also at increased risk of severe infection. The introduction of fluoroquinolones with increased activity against Streptococcus pneumoniae and other CAP pathogens has been an important development, with recent guidelines recommending the use of respiratory fluoroquinolones as a first-line choice in outpatients with modifying factors, nursing home residents, and hospitalised patients in medical wards. Of the fluoroquinolones currently available that have antipneumococcal activity, levofloxacin is well tolerated and effective. It has been approved by the Food and Drug Administration (FDA) for treatment of CAP and widespread use has shown it to be very safe.

    2011-08-01

    It is advocated that patients with high-risk non-muscle-invasive bladder cancer (NMIBC) receive an adjuvant course of intravesical Bacille Calmette-Guerin (BCG) as first-line treatment. However, a substantial proportion of patients will 'fail' BCG, either early with persistent (refractory) disease or recur late after a long disease-free interval (relapsing). Guideline recommendation in the 'refractory' setting is radical cystectomy, but there are situations when extirpative surgery is not feasible due to competing co-morbidity, a patient's desire for bladder preservation or reluctance to undergo surgery. In this review, we discuss the contemporary management of NMIBC in patients who have failed prior BCG and are not suitable for radical surgery and highlight the potential options available. These options can be categorised as immunotherapy, chemotherapy, device-assisted therapy and combination therapy. However, the current data are still inadequate to formulate definitive recommendations, and data from ongoing trials and maturing studies will give us an insight into whether there is a realistic efficacious second-line treatment for patients who fail intravesical BCG but are not candidates for definitive surgery.

    Extracorporeal membrane oxygenation (ECMO) is commonly used to treat postcardiotomy cardiopulmonary dysfunction in small children. System readiness, need for additional blood products, and exposure to new surfaces are important considerations, particularly when used for resuscitation. We reviewed our experience with a cardiopulmonary bypass (CPB) system modified to provide extended circulatory support system after surgery in patients considered at high risk. When not used in the operating room, the system was recirculated for 24 hours. Before being discarded, blood samples were obtained for activated clotting time, arterial blood gas, and blood cultures from 10 circuits. Between January 2004, and December 2005, 44 patients underwent cardiac repair using this CPB system. ECMO support was initiated in the operating room in 8 patients, and six circuits were used after patient arrival in the intensive care unit. Blood sampling after 24 hours on standby circuits revealed acceptable values for pH, Pao2, hematocrit, ionized calcium, potassium level, and ACT. All blood cultures were negative at 5 days. Survival for patients who received a circuit on standby was 64%.This modified cardiopulmonary circuit can be transformed into a simple, safe, and effective ECMO support system. Deployment of a CPB circuit previously used for cardiac repair has many advantages and maximizes utilization of resources.

    Full Text Available Abnormal changes were detected in EEG in patients with high risk of ischemic stroke (higher level than in the population. These changes show the disturbances in forming mechanisms of functional condition of cerebrum during the calm wakeful period. Changes were represented by: the registration of EEG IV- type (the E.A. Zhirmunsky type which was characterized by disorganization of alpha activity and of slow waves; the instability of pattern during the record of background activity; the paroxysmal activity in form of flashes of the bilateral synchronized waves; the strengthening of low-frequency and high-amplitude β-activity. Revealed changes in EEG show the presence of initial disturbed cerebral circulation and can be recommended as predictors of these disturbances.

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

    Fine particulate matter air pollution (PM2.5) and extreme temperatures have both been associated with alterations in blood pressure (BP). However, few studies have evaluated their joint haemodynamic actions among individuals at high risk for cardiovascular events. We assessed the effects of short-term exposures during the prior week to ambient PM2.5 and outdoor temperature levels on resting seated BP among 2078 patients enrolling into a cardiac rehabilitation programme at the University of Michigan (from 2003 to 2011) using multiple linear regression analyses adjusting for age, sex, BMI, ozone and the same-day alternate environmental factor (i.e. PM2.5 or temperature). Mean PM2.5 and temperature levels were 12.6 ± 8.2 μg/m and 10.3 ± 10.4°C, respectively. Each standard deviation elevation in PM2.5 concentration during lag days 4-6 was associated with significant increases in SBP (2.1-3.5 mmHg) and DBP (1.7-1.8 mmHg). Conversely, higher temperature levels (per 10.4°C) during lag days 4-6 were associated with reductions in both SBP (-3.6 to -2.3 mmHg) and DBP (-2.5 to -1.8 mmHg). There was little evidence for consistent effect modification by other covariates (e.g. demographics, seasons, medication usage). Short-term exposures to PM2.5, even at low concentrations within current air quality standards, are associated with significant increases in BP. Contrarily, higher ambient temperatures prompt the opposite haemodynamic effect. These findings demonstrate that both ubiquitous environmental exposures have clinically meaningful effects on resting BP among high-risk cardiac 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.

    Full Text Available Background We examined whether the combination of waist (WC and thigh (ThC circumference improves the prediction of visceral adipose tissue (VAT over WC and ThC independently in HIV-infected men and women after correction for age. We also examined the independent associations between VAT, and the combination of WC and ThC with metabolic risk factors, metabolic syndrome, type 2 diabetes mellitus (T2DM and prior cardiovascular events in HIV-infected individuals. Methods Consecutive patients attending the metabolic clinic of the University of Modena in Italy between 2005 and 2009 were recruited in this cross-sectional study. Total and regional fat mass and lean mass were quantified using DEXA. A single CT image was taken for quantification of VAT and CAC. Prior cardiovascular events which occurred within a 5-year period of the clinical evaluation were analysed. A cross-fold test was used to explore different models in the ability to predict VAT in order to build an algorithm for VAT estimation (e-VAT. Regression analysis were performed to determine the univariate and multivariate relations between WC, ThC, and age with VAT. A comparison of beta coefficients for VAT and e-VAT to predict cardio-metabolic risk and events were performed using multivariable regression models after correction for BMI and age. Results 2322 HIV-infected patients were recruited: median duration of HIV infection was 182 months (IQR 126–236; median nadir and current CD4 were 172 (IQR 68–262 and 515.5 (IQR 369–700 and 75% of them had undetectable HIV1-VL. In this abstract only the results of men will be presented. Men (n=1481 had a mean age of 45.9±7.3 years, a BMI of 24.1 ± 3.8 kg/m2, a WC of 88.0±10.1 cm and a ThC of 47.8±4.3 cm. e-VAT algorithm for men was: (5.44*WC−(1.35*ThC−(1.70*age−348.1 In men, at multivariable regression models after correction for BMI and age, e-VAT was concordant to VAT in predicting HOMA, MetS Risk, prior cardiovascular events (OR=1

    A shallow olfactory sulcus has been reported in schizophrenia, possibly reflecting abnormal forebrain development during early gestation. However, it remains unclear whether this anomaly exists prior to the onset of psychosis and/or differs according to illness stage. In the current study, magnetic resonance imaging was used to investigate the length and depth of the olfactory sulcus in 135 ultra high-risk (UHR) individuals [of whom 52 later developed psychosis (UHR-P) and 83 did not (UHR-NP)], 162 patients with first-episode psychosis (FEP), 89 patients with chronic schizophrenia, and 87 healthy controls. While there was no group difference in the length of the sulcus, UHR-P subjects had significantly shallower olfactory sulcus at baseline as compared with UHR-NP and control subjects. The depth of this sulcus became increasingly more superficial as one moved from UHR-P subjects to FEP patients to chronic schizophrenia patients. Finally, the depth of the olfactory sulcus in the UHR-P subjects was negatively correlated with the severity of negative symptoms. These findings suggest that the altered depth of the olfactory sulcus, which exists before psychosis onset, could be predictive of transition to psychosis, but also suggest ongoing changes of the sulcus morphology during the course of the illness.

    To investigate how patients with central visual field loss (CFL) complete adaptive gait tasks when compared to visual normals and determine whether task difficulty significantly affects movement control. Ten patients with CFL and 12 visual normals negotiated a floor-based obstacle (of different heights, 5 and 10 cm) and also walked across an unobstructed laboratory (no obstacle present). Analysis assessed the kinematics of human movement for each task. During obstacle crossing, compared to visual normals, patients with CFL lifted their lead and trail foot significantly higher to avoid the obstacle, reduced horizontal crossing velocity (only significant at low obstacle height), and increased head flexion to look down at more immediate areas of the ground (P walking only trials there was no significant difference between the two groups in any of the kinematic measures. CONCLUSIONS; Compared to visual normals, patients with CFL adopt a cautious gait strategy during tasks that present a high risk of falling, such as obstacle crossing. However, under conditions that present a low risk of tripping or falling, such as level walking, differences appear minimal.

    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.

    The TLR7/8 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 with or without Resiquimod in high-risk melanoma patients. In Part I of the study, patients received 100ug full length NY-ESO-1 protein emulsified in 1.25mL Montanide (day 1) followed by topical application of 1000mg 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 100ug NY-ESO-1 protein plus Montanide (day 1) followed by topical application of placebo gel (Arm-A; N=8) or 1000mg 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.

    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.

    Conclusion: This new technique and device requires greater caution and needs more practice to accumulate sufficient experience. The studied patients were very fragile, due to old age and multiple comorbidities. Our results are similar to findings of multicenter trials. With careful patient screening and selection, TAVI can be a promising treatment for high-risk severe AS patients.

    Epidemiological studies showed that PR prolongation is associated with increased risk of adverse cardiovascular outcomes. We investigated the relations of PR interval with indices of vascular function and endothelial repair as the underlying mechanisms. The study comprised 348 high-risk patients with prior coronary artery disease, ischemic stroke, and/or diabetes mellitus recruited from medical outpatient clinics and 150 healthy subjects without such a history. PR interval was considered prolonged if >200 ms, as determined from resting 12-lead electrocardiogram. Vascular function was assessed by brachial flow-meditated dilatation (FMD) using high-resolution ultrasound. Circulating CD133(+)/KDR(+) endothelial progenitor cell (EPC) levels were measured by flow cytometry. Among healthy subjects, PR interval was inversely associated with FMD (R = -0.20, P = 0.015), but not with the level of circulating CD133(+)/KDR(+) EPC (R = 0.05, P = 0.58). Among high-risk cardiovascular patients, PR prolongation >200 ms was more common compared with healthy subjects (45/348 (13 %) versus 4/150 (3 %), P PR interval was associated inversely with FMD (R = -0.14, P = 0.01) and positively with circulating CD133(+)/KDR(+) EPC level (R = +0.14, P = 0.009). Circulating CD133(+)/KDR(+) EPC level was significantly increased in patients with PR prolongation >200 ms (0.87 ± 0.37 versus 0.68 ± 0.42 (log, ×10(-3)/ml), P = 0.005). Adjusted for potential confounders, increased PR interval remained independently associated with increased CD133(+)/KDR(+) EPC by +0.002 (95 % confidence interval (CI) 0.000 to 0.004 (log, ×10(-3)/ml), P = 0.011) and depressed FMD (B = -0.014 %, 95 % CI -0.027 to -0.002, P = 0.026). PR prolongation is associated with endothelial dysfunction and evidence of endothelial repair activation in patients with high cardiovascular risk.

    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.

    Erectile dysfunction (ED) is associated with cardiovascular risk factors as elevated systolic blood pressure (SBP), resting high heart rate (HR), and endothelial dysfunction and predicts cardiovascular events. However, the interaction between high HR and SBP and the development of ED remains unclear. We evaluated 1015 male patients enrolled in the ED substudy of ONTARGET and TRANSCEND, examining the influence of mean HR and mean SBP obtained over all study visits (mean 10.9±1.4 study visits) and their interaction with ED. In patients without pre-existing ED, new onset ED was detected in 29% of patients below, and 41% of patients above, the median of mean HR (OR 1.72, 95% CI 1.8-2.5, p = 0.0047). In patients with pre-existing ED, high HR had no add-on effect. With or without pre-existing ED, high SBP had no influence after adjustment for covariates (OR 1.03, 95% CI 0.66-1.59, p = 0.91). In a continuous model, it was shown that effects of high HR were prominent at low Kölner (Cologne) Evaluation of Erectile Function (KEED) score baseline values and in the presence of SBP above the median. In patients at risk for cardiovascular events, high HR is associated with ED, whereas the effect of high SBP was not significant. High resting HR might represent a cardiovascular risk indicator. Whether HR represents a potential treatment target to improve ED in high-risk individuals must be scrutinized in prospective trials.

    Full Text Available Background: The aim of this study was the independent psychosis risk factors assessment in a group of subjects fulfilling the criteria of at risk mental state, under specialist outpatient psychiatric care. Participants: Seventy-one patients – 33 women and 38 men, were involved into this study, aged on average 17.34, all under psychiatric care. The patients were recruited into the study in the sequence of their outpatient clinic admission. The criterion to be included into the study was the diagnosis of ultra-high risk state (UHRS – defined according to the Australian research group principles. Subsequently, the patients were divided into subgroups according to the clinical features of their mental state. Method: The author’s demographic questionnaire was applied in the study. Information regarding the family history of psychosis was obtained from patients and/or their relatives or carers. The patients’ mental state was assessed monthly – according to the presence of psychotic symptoms, change of their incidence and duration, presence of depressive symptoms or aggressive behaviour (measured by a three-level scale. On the basis of the obtained information, we evaluated: 1 conversion into psychosis time – measured from diagnosing of UHRS to the development of full-symptom psychosis, 2 therapeutic methods used (psychotherapy, pharmacotherapy or both, 3 use of psychoactive substances after being diagnosed with UHRS, 4 presence of serious life stressors (the patients’ subjective estimation – during the six-month period preceding the conversion into psychosis. Results: 1 In the UHRS group of patients, staying under professional outpatient psychiatric care, the use of marijuana was an independent risk factor of conversion into psychosis. 2 In the investigated group of patients with at risk mental state we did not find any correlation between modulating factors (including: therapeutic methods used, depressive symptoms, aggression or

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

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

    BACKGROUND: An increasing proportion of patients with acute coronary syndrome (ACS) requiring percutaneous coronary intervention (PCI) are classified as elderly (aged =70 years). The glycoprotein IIb/IIIa inhibitor abciximab is known to reduce adverse outcomes in patients aged high......-risk ACS undergoing PCI, but conflicting findings relating to its effects in the elderly have been reported. OBJECTIVE: The aim of this study was to evaluate the effect of abciximab in elderly high-risk ACS patients undergoing PCI. METHODS: From our dedicated PCI registry we identified 2068 ACS patients...... with high-risk lesions that were treated with PCI. Baseline data were collected prospectively. All-cause mortality, target vessel revascularization (TVR), myocardial infarction (MI), and the combination of these were primary study endpoints. All endpoints within 1 year after PCI were registered...

  9. Endovascular Treatment of Infrarenal Abdominal Aortic Aneurysm with Short and Angulated Neck in High-Risk Patient

    2013-01-01

    Full Text Available Endovascular treatment of abdominal aortic aneurysms (AAA is an established alternative to open repair. However lifelong surveillance is still required to monitor endograft function and signal the need for secondary interventions (Hobo and Buth 2006. Aortic morphology, especially related to the proximal neck, often complicates the procedure or increases the risk for late device-related complications (Hobo et al. 2007 and Chisci et al. 2009. The definition of a short and angulated neck is based on length (60° (Hobo et al. 2007 and Chisci et al. 2009. A challenging neck also offers difficulties during open repairs (OR, necessitating extensive dissection with juxta- or suprarenal aortic cross-clamping. Patients with extensive aneurysmal disease typically have more comorbidities and may not tolerate extensive surgical trauma (Sarac et al. 2002. It is, therefore, unclear whether aneurysms with a challenging proximal neck should be offered EVAR or OR (Cox et al. 2006, Choke et al. 2006, Robbins et al. 2005, Sternbergh III et al. 2002, Dillavou et al. 2003, and Greenberg et al. 2003. In our case the insertion of a thoracic endograft followed by the placement of a bifurcated aortic endograft for the treatment of a very short and severely angulated neck proved to be feasible offering acceptable duration of aneurysm exclusion. This adds up to our armamentarium in the treatment of high-risk patients, and it should be considered in emergency cases when the fenestrated and branched endografts are not available.

    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.

    Background: The most important factors for prognosis of cervical cancers are age and histological criteria such as the tumor size, the involvement of lymph nodes, lympho-vascular space involvement as well as microvessel involvement and poor tumor differentiation (grading 3). Here we present the results of concomitant chemo-radiation at high-risk situation of patients with cervical cancer after surgery. Patients and Methods: The study comprised 34 patients with median age of 40 years (26-63 years) after Wertheim surgical technique for cervical cancer at the FIGO Stages IB (n = 19) and IIB (n = 15). All patients were treated between November 1995 and June 1999 by a schedule of concomitant chemoradiation. The indication for this treatment was given by the positive histological proof of lymph node metastasis, microvessel or lympho-vascular space involvement as well as a G3 grading. The chemo-therapy was given in week 1 and 5 (day 1-5 and day 29-33). The dosage of cisplatin was 20 mg/m{sup 2}/d on every day and 5-FU was given as a 120-h infusion with 600 mg/m{sup 2}/d. The external beam radiotherapy was applied to the pelvis with 1.8 Gy per fraction up to 50.4-54 Gy. In two patients the paraaortal region was irradiated too because of the involvement of these lymph nodes. Results: The median observation time was 48 months (3-68 months). 30 patients are alive (88%) in complete response. Four patients died. The mean survival was 61 {+-} 3 months. We have seen only slight acute toxicities of grade 1 and 2. Three patients suffered from a grade 3 diarrhea and three patients developed a grade 3 leukopenia. In seven patients we found a secondary lymphedema as a late toxicity. Conclusion: The concomitant chemoradiation containing cisplatin in high-risk situation for cervical cancer after surgery improves the outcome and survival in these patients. (orig.)

    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.

    Wang Robert C

    2011-10-01

    Full Text Available Abstract Background The human papillomaviruses (HPV are a large family of non-enveloped DNA viruses, mainly associated with cervical cancers. Recent epidemiologic evidence has suggested that HPV may be an independent risk factor for oropharyngeal cancers. Evidence now suggests HPV may modulate the malignancy process in some tobacco- and alcohol-induced oropharynx tumors, but might also be the primary oncogenic factor for inducing carcinogenesis among some non-smokers. More evidence, however, is needed regarding oral HPV prevalence among healthy adults to estimate risk. The goal of this study was to perform an HPV screening of normal healthy adults to assess oral HPV prevalence. Methods Healthy adult patients at a US dental school were selected to participate in this pilot study. DNA was isolated from saliva samples and screened for high-risk HPV strains HPV16 and HPV18 and further processed using qPCR for quantification and to confirm analytical sensitivity and specificity. Results Chi-square analysis revealed the patient sample was representative of the general clinic population with respect to gender, race and age (p Conclusions The successful recruitment and screening of healthy adult patients revealed HPV16, but not HPV18, was present in a small subset. These results provide new information about oral HPV status, which may help to contextualize results from other studies that demonstrate oral cancer rates have risen in the US among both females and minorities and in some geographic areas that are not solely explained by rates of tobacco and alcohol use. The results of this study may be of significant value to further our understanding of oral health and disease risk, as well as to help design future studies exploring the role of other factors that influence oral HPV exposure, as well as the short- and long-term consequences of oral HPV infection.

    The purpose of this article is to discuss the impact of the training program for predoctoral dental and hygiene students at Loma Linda University School of Dentistry (LLUSD) with regard to issues related to treating patients with a high risk of having HIV/AIDS. LLUSD offers a training program for fourth-year dental hygiene and predoctoral dental students that addresses the oral health care needs of persons with HIV disease. The training occurs in small groups 2 days per week at a community clinic serving HIV-positive individuals. Three academic quarters are required to train all fourth-year students each year. Evaluation of program effectiveness is conducted by means of pre- and post-session surveys. Dental hygiene and dental students completed the pre-survey during the spring quarter of their third year in public health dentistry courses. The same students completed the post-session survey at the end of their weekly training sessions during the fourth year. The overall change in all areas related to the students' comfort level in treating patients in the 3 defined categories is in a positive direction (p-valuedental hygiene students compared with predoctoral dental students. A comparison of pre- and post-session surveys reveals a significant improvement in students' perception of and comfort level with treating patients who are homosexual/bisexual or intravenous drug users, or who have a history of blood transfusion in both student groups upon completion of the HIV and the Dentist training program at LLUSD.

  17. Potential of a Pharmacogenetic-Guided Algorithm to Predict Optimal Warfarin Dosing in a High-Risk Hispanic Patient

    Directory of Open Access Journals (Sweden)

    Dagmar F. Hernandez-Suarez MD

    2016-12-01

    Full Text Available 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.

    BACKGROUND: Nonvariceal upper gastrointestinal bleeding (UGIB) is a serious medical condition requiring prompt resuscitation and early endoscopic therapy in those with high-risk endoscopic lesions (HRLs). There are little or no data correlating sole blood urea nitrogen (BUN) level with the severity of nonvariceal UGIB or the presence of HRLs in the adult population. OBJECTIVES: To determine if the BUN level on presentation correlates with parameters of severity of UGIB (need for blood transfusion or intensive care unit [ICU] admission) or to the subsequent finding of HRL, and in so doing identify patients who will require early endoscopic intervention. METHODS: The Canadian Registry of patients with Upper Gastrointestinal Bleeding undergoing Endoscopy was used to identify patients enrolled from the McGill University Health Centre (Montreal, Quebec) who presented with or developed acute nonvariceal UGIB while admitted. All comparisons were performed using Student’s t test or Wilcoxon’s signed rank test, as appropriate. Logistic regression modelling using a stepwise method was performed to identify independent predictors of severe nonvariceal UGIB and HRL. RESULTS: Two hundred nine patients were enrolled in the study. The mean age was 67±18 years and 59.8% were male. The mean BUN level was 13.4±9.4 mmol/L. Univariate analysis demonstrated that the BUN level was a significant predictor of ICU admission (BUN 14.7±10.4 mmol/L versus 12.0±8.0 mmol/L, P=0.035). However, when adjusted for systolic blood pressure, BUN level became a weaker predictor of ICU admission, just failing to achieve statistical significance (OR 1.03, 95% CI 1.00 to 1.06; P=0.08). Univariate analysis also demonstrated that BUN level was not a statistically significant predictor of blood transfusion requirement (BUN 14.1±10.6 mmol/L versus 13.6±8.6 mmol/L, P=0.508), nor of HRL (BUN 14.2±10.7 mmol/L versus 12.9±8.6 mmol/L, P=0.605). CONCLUSION: In patients with nonvariceal UGIB, the BUN

    Acute high levels of anger and anxiety are associated with an elevated risk of myocardial infarction (MI) in the following two hours. MIs preceded by these acute negative emotions may also have a poor long-term prognosis, but information about high-risk patients is lacking. We examined whether young age and female sex are associated with MIs that are preceded by negative emotions and whether age and sex moderate the subsequent increased mortality risk following MI preceded by negative emotions. We conducted a secondary analysis of the Determinants of Myocardial Infarction Onset Study (N=2176, mean age=60.1±12.3years, 29.2% women). Anxiety and anger immediately prior to (0-2h) MI and the day before (24-26h) MI were assessed using a structured interview. Subsequent 10-year all-cause mortality was determined using the US National Death Index. Anxiety during the 0-2h pre-MI period was associated with younger age (OR=0.98,95% CI=0.96-0.99 per year) and female sex (OR=1.50,95% CI=1.11-2.02). Anger in the 0-2h pre-MI period was also associated with younger age (OR=0.95,95% CI=0.94-0.96) but not with sex (OR=0.93,95% CI=0.67-1.28). During follow-up, 580 (26.7%) patients died. Mortality rate was higher if MI occurred immediately after high anxiety, particularly in patients ≥65years (HR=1.80,95% CI=1.28-2.54) vs. younger patients (HR=0.87,95% CI=0.55-1.40; p-interaction=0.015). Other interactions with sex or anger were not significant. Patients with high anxiety or anger levels in the critical 2-hour period prior to MI are younger than those without such emotional precipitants. In addition, pre-MI anxiety is associated with an elevated 10-year mortality risk in patients aged ≥65years. Copyright © 2016 Elsevier Inc. All rights reserved.

    2009-12-01

    Full Text Available Purpose: In this study, we investigated the ability of UroVysion™ to assess response to intravesical therapy in patients with high risk superficial bladder tumors. Materials and methods: We performed a retrospective review of patients undergoing intravesical therapy for high risk superficial bladder tumors. Urine specimens were collected for UroVysion™ analysis before and immediately after a course of intravesical therapy. Cytology and cystoscopy were performed six weeks after treatment, using either a positive cytology or visible abnormality on cystoscopy as a prompt for biopsy. The operating characteristics of the UroVysion™ test were then determined. Results: 41 patients were identified in whom 47 cycles of induction and 41 cycles of maintenance intravesical therapy were given during the study period. This yielded a total of 88 treatment and evaluation cycles. Median follow-up was 9 months per induction (range 1-21 months and 13 months per patient (range 1-25 months. A total of 133 urine samples were collected for UroVysion™ of which 40 were positive. Based upon standard clinical evaluation, 41 biopsies were performed which detected 20 recurrences. UroVysion™ testing performed immediately upon completion of therapy for the 41 patients undergoing biopsy yielded a sensitivity, specificity, and accuracy of 85%, 61%, and 71%. Conclusions: The use of UroVysion™ following intravesical therapy for high-risk superficial bladder tumors helps to identify patients at high risk of refractory or recurrent disease who should undergo immediate biopsy under anesthesia.

    The posaconazole extended release tablet formulation was developed to improve bioavailability relative to the oral suspension. Therapeutic drug monitoring has been used to optimise posaconazole dosing to achieve a target trough level ≥0.7 μg ml(-1). We retrospectively evaluated 28 patients with haematological malignancies who received posaconazole tablets for antifungal prophylaxis. Posaconazole serum trough levels were obtained 5 days after initiation of therapy. Mean trough level was 1.19 ± 0.63 μg ml(-1), and 71% achieved a trough level ≥0.7 μg ml(-1). Diarrhoea was associated with lower mean trough levels (0.65 ± 0.08 μg ml(-1) vs. 1.31 ± 0.13 μg ml(-1)), P = 0.002. Mean trough levels were lower in patients ≥90 kg (0.74 ± 0.09 μg ml(-1)) vs. Posaconazole delayed release tablets attain appropriate trough levels in most patients, but patients with a higher weight and those experiencing diarrhoea are more likely to have lower levels.

    Genetic predisposition is involved in only 10% of patients with breast cancer. This study was to evaluate the impact of prophylactic surgery. This is a retrospective study of 61 patients who received prophylactic breast surgery. Data collection was carried out through the computer file of the ICO. The inclusion criteria were: patients who benefited from a bilateral prophylactic mastectomy. There were no exclusion criteria. Patients received a satisfaction questionnaire to complete. Our study included 61 patients, 67% had a history of breast cancer. Bilateral prophylactic surgery was performed in 40 patients. It was made an average of two interventions, 44.3% of them presented postoperative complications, 18% recovery. Forty-three patients were satisfied with the medical information before surgery. The end result matched the expectations of 54.4% and 67.4% of patients would be ready to start. It was found pain associated with breast surgery in 56.5% of patients and almost half reported a change in their sexual life. Prophylactic mastectomy is the most effective technique to prevent the risk of breast cancer. The consequences of such an action are important. It is necessary to better select patients who would benefit most from this type of surgery. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Full Text Available Human papillomavirus (HPV infection has been demonstrated in some of the nonmelanoma skin cancers as well as in precancerous lesions. Multiple infections of mucosal high-risk HPV may contribute to the onset of digital Bowen's disease through, if any, digital-genital transmission. We screened for the presence of the mucosal HPV DNA in patients with extragenital Bowen's disease (, squamous cell carcinoma (, bowenoid papulosis (, verrucous carcinoma (, actinic keratosis (, and basal cell carcinoma (. We used a PANArray HPV Genotyping Chip for high-risk and low-risk mucosal types. Genotyping data was confirmed using a conventional direct DNA sequencing method. Two cases of extragenital Bowen's disease were positive for types 16 and 33 of mucosal HPV, respectively. None of the squamous cell carcinoma cases were positive. Neither patients with digital Bowen's disease ( nor those with squamous cell carcinoma ( showed any mucosal high-risk HPV. Mucosal high-risk HPV DNA was confirmed in 5 (55.6% of the 9 patients with bowenoid papulosis. HPV 16 was most prevalent (, while the DNA of HPVs 35 and 67 was detected in one sample for each of the two types. Our study demonstrated that two (6.7% of the patients with 30 extragenital Bowen's disease were positive for types 16 and 33 of mucosal HPV, respectively. HPVs belonging to the mucosal high-risk group may participate in the development of extragenital Bowen's disease. However, we could not find any relationship between the mucosal high-risk HPV and Bowen's disease or squamous cell carcinoma in the fingers.

    Highlights: • We assessed the accuracy of FDG-PET/contrast enhanced CT (FDG-PET/ceCT) in the detection of unsuspected recurrence of colorectal cancer. In regard to our knowledge, no previous experience has been reported about the combined acquisition and interpretation of a FDG-PET/ceCT in the surveillance of colorectal cancer. • We designed a prospective study and performed an individual and combined assessment of both techniques (PET and ceCT), in a patient-based analysis and a lesion-based analysis. • The value of PET and ceCT was found to be similar in the detection of unsuspected recurrence of CRC in a patient-based analysis. The most interesting of our result, is that the combined assessment of PET/ceCT improves the accuracy in the lesion-based analysis. - Abstract: Objective: To assess the accuracy of FDG-PET/contrast enhanced CT (FDG-PET/ceCT) in the detection of unsuspected recurrence of colorectal cancer (CRC) in patients with high risk of relapse. Methods: Thirty-three patients (14 females and 19 males, mean age: 62, range: 41–78), with CRC in complete remission, were prospectively included. All patients underwent FDG-PET/ceCT (58 studies). FDG-PET/ceCT was requested in the surveillance setting, and performed following a standardized protocol. A portal venous phase CT scan was performed after the injection of iodinated contrast agent. An individual and combined assessment of both techniques (PET and ceCT) was performed. Concordant and discordant findings of PET, ceCT and FDG-PET/ceCT were compared in a patient-based and a lesion-based analysis. The final diagnosis, recurrence or disease free status (DFS), were established by histopathology or clinical/radiological follow-up of at least 6 months. Results: Seven out of 33 patients had a confirmed recurrence and the rest of patients had a DFS. In a patient-based analysis the sensitivity and specificity of PET, ceCT and PET/ceCT was of 86% and 88%, 86% and 92%, 86% and 85%, respectively. Attending to

    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. 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. 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). 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. ClinicalTrials.gov, no. NCT01071265. © 2016 Canadian Medical Association or its licensors.

    Full Text Available Abstract Background Multiple randomized controlled trials (RCTs have examined the cardiovascular effects of omega-3 fatty acids and have provided unexplained conflicting results. A meta-analysis of these RCTs to estimate efficacy and safety and potential sources of heterogeneity may be helpful. Methods The Cochrane library, MEDLINE, and EMBASE were systematically searched to identify all interventional trials of omega-3 fatty acids compared to placebo or usual diet in high-risk cardiovascular patients. The primary outcome was all-cause mortality and secondary outcomes were coronary restenosis following percutaneous coronary intervention and safety. Meta-analyses were carried out using Bayesian random-effects models, and heterogeneity was examined using meta-regression. Results A total of 29 RCTs (n = 35,144 met our inclusion criteria, with 25 reporting mortality and 14 reporting restenosis. Omega-3 fatty acids were not associated with a statistically significant decreased mortality (relative risk [RR] = 0.88, 95% Credible Interval [CrI] = 0.64, 1.03 or with restenosis prevention (RR = 0.89, 95% CrI = 0.72, 1.06, though the probability of some benefit remains high (0.93 and 0.90, respectively. However in meta-regressions, there was a >90% probability that larger studies and those with longer follow-up were associated with smaller benefits. No serious safety issues were identified. Conclusions Although not reaching conventional statistical significance, the evidence to date suggests that omega-3 fatty acids may result in a modest reduction in mortality and restenosis. However, caution must be exercised in interpreting these benefits as results were attenuated in higher quality studies, suggesting that bias may be at least partially responsible. Additional high quality studies are required to clarify the role of omega-3 fatty acid supplementation for the secondary prevention of cardiovascular disease.

    The incremental prognostic value of the plaque features in coronary computed tomographic angiography (CTA) has not been well assessed. This study was designed to determine whether CTA high-risk plaques have prognostic value incremental to the Framingham risk score (FRS) and the severity of luminal obstruction. A total of 628 newly symptomatic patients without known coronary artery disease underwent CTA. They were followed for a median of 677 days during which there were 26 cardiac events, including cardiac death, acute myocardial infarction, and hospitalization for unstable angina. Incremental prognostic value of adding plaque characteristics to the number of diseased vessels and the FRS was evaluated using 3 Cox models and net reclassification indexes. The discrimination index was significantly increased by adding the number of diseased vessels to the FRS (change in c-statistic from 65.8% to 78.6%, p=0.028) but not significantly by further adding plaque characteristics (change in c-statistic from 78.6% to 80.0%, p=0.812). However, improved model-fitting by adding plaque characteristics into the linear combination with risk score and the number of diseased vessels (p=0.007 from likelihood ratio test) and the lowest value of Akaike's information criteria of that model indicated that plaque characteristics improved both predictive accuracy and discrimination perspective. More subjects reclassified by plaque characteristics were moved to directions consistent with their subsequent cardiac event status than in an inconsistent direction. Evaluation of CTA plaque characteristics may provide incremental prognostic value to the number of diseased vessels and the FRS. Copyright © 2015 Japanese College of Cardiology.

    Full Text Available Zheng-Xiong XiNational Institute on Drug Abuse, Intramural Research Program, Baltimore, MD, USAAbstract: Smoking is still the most prominent cause of preventable premature death in the United States and an increasing cause of morbidity and mortality throughout the world. Although the current treatments such as nicotine replacement therapy (NRT and bupropion are effective, long-term abstinence rates are low. Mechanism studies suggest that the pleasurable effects of smoking are mediated predominantly by nicotine, which activates the brain reward system by activation of brain α4β2 nicotinic acetylcholine receptors (nAChRs. Varenicline is a novel α4β2 nAChR partial agonist and has been found to be even more effective than NRT or bupropion in attenuating smoking satisfaction and in relieving craving and withdrawal symptoms after abstinence. Thus, varenicline has been recently approved to be a first-line medication for smoking cessation in the United States and European countries. Varenicline is generally well tolerated in healthy adult smokers, with the most commonly reported adverse effects being nausea, insomnia, and headache. However, growing postmarketing data has linked varenicline to an increase in neuropsychiatric symptoms such as seizures, suicidal attempts, depression, and psychosis as well as serious injuries potentially relating to unconsciousness, dizziness, visual disturbances, or movement disorders. Therefore, new safety warnings are issued to certain high risk populations, such as patients with mental illness and operators of commercial vehicles and heavy machinery. In particular, pilots, air traffic controllers, truck and bus drivers have been banned from taking varenicline.Keywords: nicotine, varenicline, α4β2 nicotinic acetylcholine receptor, nAChRs, partial agonist, smoking cessation

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

    Full Text Available Vassilis Fragoulakis, Georgia Kourlaba, Nikolaos ManiadakisDepartment of Health Services and Management, National School of Public Health, Athens, GreeceBackground: An economic evaluation was undertaken in order to assess several therapeutic alternatives (rosuvastatin, atorvastatin, simvastatin, and pravastatin for the prevention of primary and secondary cardiovascular events in high-risk patients in Greece.Methods: A probabilistic Markov model with five distinct states provided estimates over a 20-year time span. The relative effectiveness of comparators was based on the literature. The HellenicSCORE risk equation was used to forecast survival. The transition probabilities from acute myocardial infarction or stroke to death were estimated with reference to the Framingham study. In addition, Framingham scores were used to calculate the probability of nonfatal acute myocardial infarction or nonfatal stroke. Costs were estimated from the perspective of sickness funds and included direct medical costs valued in the year 2012. The total treatment cost accounted for the cost of drugs, routine examinations, and resources expended in the management of acute myocardial infarction, stroke, and death. The utility decrements used are those for the Greek population. A supplementary budget impact analysis was also conducted.Results: The mean discounted quality-adjusted life years in the case of males for the rosuvastatin arm were 10.18 versus 10.04, 9.94, and 9.88 for atorvastatin, simvastatin, and pravastatin, respectively. The mean total cost was €15,392, €16,438, €17,009, and €17,356 for rosuvastatin, atorvastatin, simvastatin, and pravastatin, respectively. Similar results were obtained in the case of females, while all analyses demonstrated a statistically significant difference at the 95% level of significance. The total burden of 100% (single use of rosuvastatin in a hypothetical cohort of 100 male patients for one year was €1.47 million

    Studies have challenged the appropriateness of accepted blood pressure targets. We hypothesised that different levels of low blood pressure are associated with benefit for some, but harm for other outcomes. In this analysis, we assessed the previously reported outcome data from high-risk patients aged 55 years or older with a history of cardiovascular disease, 70% of whom had hypertension, from the ONTARGET and TRANSCEND trials investigating ramipril, telmisartan, and their combination, with a median follow-up of 56 months. Detailed descriptions of randomisation and intervention have already been reported. We analysed the associations between mean blood pressure achieved on treatment; prerandomisation baseline blood pressure; or time-updated blood pressure (last on treatment value before an event) on the composite outcome of cardiovascular death, myocardial infarction, stroke, and hospital admission for heart failure; the components of the composite outcome; and all-cause death. Analysis was done by Cox regression analysis, ANOVA, and χ(2). These trials were registered with ClinicalTrials.gov, number NCT00153101. Recruitment for ONTARGET took place between Dec 1, 2001, and July 31, 2008. TRANSCEND took place between Nov 1, 2001, and May 30, 2004. 30 937 patients were recruited from 733 centres in 40 countries and followed up for a median of 56 months. In ONTARGET, 25 127 patients known to be tolerant to angiotensin-converting-enzyme (ACE)-inhibitors were randomly assigned after a run-in period to oral ramipril 10 mg/day (n=8407), telmisartan 80 mg/day (n=8386), or the combination of both (n=8334). In TRANSCEND, 5810 patients who were intolerant to ACE-inhibitors were randomly assigned to oral telmisartan 80 mg/day (n=2903) or placebo (n=2907). Baseline systolic blood pressure (SBP) 140 mm Hg or higher was associated with greater incidence of all outcomes compared with 120 mm Hg to less than 140 mm Hg.

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

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

    Full Text Available Aim. The effect of psoas compartment and sciatic nerve block combination on hemodynamic parameters in high risk geriatric patients with hip fracture surgeries was evaluated. Methods. In this study, high risk old patients who underwent psoas compartment block and sciatic nerve block for hip surgery anesthesia were evaluated retrospectively. In Group 1 there were 14 patients with levobupivacaine and lidocaine combination and in Group 2 there were 10 patients with levobupivacaine and prilocaine combination. In our study we evaluated the heart rate, systolic blood pressure, diastolic blood pressure, mean arterial blood pressure levels and sedation need between groups, between age over and below 85 years and in all patients. Results. There were no statistically significant difference in heart rate and mean arterial blood pressure levels between groups and age groups (p˃0.05. There were a 6.18% and 16.52% decrease in mean arterial blood pressure in Group 1 and 2 respectively. When we evaluated the whole patients there was a 10.06% decrease in mean arterial blood pressure. Conclusion. We consider that the combination of psoas and sciatic block as an anesthetic method may be a proper option especially in the elderly and high-risk patients who were underwent the hip surgery.

    Rarely, patients with prostate cancer present with prostate-specific antigen (PSA) scores > 20 ng/mL but with otherwise very-low-risk disease. Oncologists have debated whether the malignancies in these patients behave more comparably to low-risk or high-risk disease. Our objective was to elucidate the behavior of these malignancies. A retrospective review was conducted of prostate cancer patients treated with radiation from 2000 to 2013. The inclusion criteria for very-low-risk disease included stage T1a-T1c, Gleason score ≤ 6, ≤ 3 positive cores, ≤ 50% involvement of any core, and PSA level high-grade, low-volume group consisted of patients with stage T1c-T2a, PSA level low-risk, and high-grade groups, respectively. Biochemical progression-free survival at 5 years was 71.3% for the divergent group, 68.8% for the high-grade group, and 98.3% for the low-risk group. The biochemical failure rate for the divergent group differed significantly from the low-risk group (P = .021), and that for the low-risk group was significantly different from that of the high-grade group (P = .025). However, the divergent group did not appear different from the high-grade group (P = .53). The results of our study have shown that the disease prognosis for the divergent-risk group is worse than that for the very-low-risk disease group and does not appear to be different from that for the low-volume, high-grade disease group. Oncologists should be aware that the outcomes for divergent patients are similarly poor to their low-volume, classically high-risk counterparts. Copyright © 2016 Elsevier Inc. All rights reserved.

    Between 30 and 50% of febrile neutropenic episodes are accounted for by infection. C-reactive protein (CRP) is a nonspecific parameter for infection and inflammation but might be employed as a trigger for diagnosis. The aim of the study was to evaluate whether {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT can be used to detect inflammatory foci in neutropenic patients with elevated CRP and whether it helps to direct treatment. Twenty-eight consecutive patients with neutropenia as a result of intensive chemotherapy for haematological malignancies or myeloablative therapy for haematopoietic stem cell transplantation were prospectively included. {sup 18}F-FDG PET/CT was added to the regular diagnostic workup once the CRP level rose above 50 mg/l. Pathological FDG uptake was found in 26 of 28 cases despite peripheral neutrophil counts less than 0.1 x 10{sup -9}/l in 26 patients: in the digestive tract in 18 cases, around the tract of the central venous catheter (CVC) in 9 and in the lungs in 7 cases. FDG uptake in the CVC tract was associated with coagulase-negative staphylococcal bacteraemia (p < 0.001) and deep venous thrombosis (p = 0.002). The number of patients having Streptococcus mitis bacteraemia appeared to be higher in patients with grade 3 oesophageal FDG uptake (p = 0.08). Pulmonary FDG uptake was associated with the presence of invasive fungal disease (p = 0.04). {sup 18}F-FDG PET/CT scanning during chemotherapy-induced febrile neutropenia and increased CRP is able to detect localized foci of infection and inflammation despite the absence of circulating neutrophils. Besides its potential role in detecting CVC-related infection during febrile neutropenia, the high negative predictive value of {sup 18}F-FDG PET/CT is important for avoiding unnecessary diagnostic tests and therapy.

    Full Text Available Three cases of rheumatoid arthritis (RA, presenting with refractory anaemia, thrombocytopenia and peripheral lymphocytosis respectively, were observed. In all the cases haematological manifestations were unrelated to disease activity or drug toxicity. These patients were detected to have pure red cell aplasia (PRCA (normocytic normochromic anaemia, reticulocytopenia and absence of erythroid precursors in the bone marrow, immune thrombocytopenia (IT (absence of splenomegaly and presence of increased megakaryocytes in the bone marrow and multiple myeloma (MM (lytic lesions on skull, paraproteinaemia and bone marrow plasmacytosis respectively. PRCA and IT responded to glucocorticoids. Association with these three haematological alterations has rarely been reported. Our report highlights the need to regularly monitor blood counts in patients with RA.

    To compare disease-specific survival and recurrence-free survival (RFS) after successful {sup 131}I ablation in patients with differentiated thyroid carcinoma (DTC) between those defined before ablation as low-risk and those defined as high-risk according to the European Thyroid Association 2006 consensus statement. Retrospective data from three university hospitals were pooled. Of 2009 consecutive patients receiving ablation, 509 were identified as successfully ablated based on both undetectable stimulated serum thyroglobulin in the absence of antithyroglobulin antibodies and a negative diagnostic whole-body scan in a follow-up examination conducted 8.1{+-}4.6 months after ablation. Of these 509 patients, 169 were defined as high-risk. After a mean follow-up of 81{+-}64 months (range 4-306 months), only three patients had died of DTC, rendering assessment of disease-specific survival differences impossible. Of the 509 patients, 12 (2.4%) developed a recurrence a mean 35 months (range 12-59 months) after ablation. RFS for the duration of follow-up was 96.6% according to the Kaplan-Meier method. RFS did not differ between high-risk and low-risk patients (p=0.68). RFS differed slightly but significantly between those with papillary and those with follicular thyroid carcinoma (p=0.03) and between those aged {<=}45 years those aged >45 years at diagnosis (p=0.018). After (near) total thyroidectomy and successful {sup 131}I ablation, RFS does not differ between patients classified as high-risk and those classified as low-risk based on TNM stage at diagnosis. Consequently, the follow-up protocol should be determined on the basis of the result of initial treatment rather than on the initial tumour classification. (orig.)

    Incisional hernia (IH) after colorectal surgery is highly prevalent. The objective of this study is to assess the utility of an algorithm to decide on mesh augmentation after a midline laparotomy for colorectal resection to prevent IH in high-risk patients. A prospective study was conducted including all patients undergoing a midline laparotomy for colorectal resection between January 2011 and June 2014, after the implementation of a decision algorithm for prophylactic mesh augmentation in selected high-risk patients. Intention-to-treat analyses were conducted between patients in which the algorithm was correctly applied and those in which it was not. From the 235 patients analysed, the algorithm was followed in 166 patients, the resting 69 cases were used as a control group. From an initial adherence to the algorithm of 40% in the first semester, a 90.3% adherence was achieved in the seventh semester. The incidence of IH decreased as the adherence to the algorithm increased (from 28 to 0%) with a time-related correlation (R(2)=0.781). A statistically significant reduction in IH incidence was demonstrated in high-risk groups in which the algorithm was correctly applied (10,2 vs. 46,3%; p=0,0001; OR: 7,58;95%; CI: 3,8-15). Survival analysis showed that the differences remained constant during follow-up. The implementation of the algorithm reduces the incidence of IH in high-risk patients. The adherence to the algorithm also correlates with a decrease in the incidence of IH. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    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.

    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. 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. 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). 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 ignificant survival advantages in high-risk URC. This may help to select candidates of adjuvant treatment in prospective studies.

  16. POTENTIAL APPLICATIONS OF IMAGE-GUIDED RADIOTHERAPY FOR RADIATION DOSE ESCALATION IN PATIENTS WITH EARLY STAGE HIGH-RISK PROSTATE CANCER

    Directory of Open Access Journals (Sweden)

    2015-02-01

    Full Text Available Patients with early stage high-risk prostate cancer (PSA >20, Gleason score >7 are at high risk of recurrence following prostate cancer irradiation. Radiation dose escalation to the prostate may improve biochemical free survival for these patients. However, high rectal and bladder dose with conventional three-dimensional conformal radiotherapy (3D-CRT may lead to excessive gastrointestinal and genitourinary toxicity. Image-guided radiotherapy (IGRT, by virtue of combining the steep dose gradient of intensity-modulated radiotherapy (IMRT and daily pretreatment imaging, may allow for radiation dose escalation and decreased treatment morbidity. Reduced treatment time is feasible with hypofractionated IGRT and it may improve patient quality of life.

  17. Presence of histopathological premalignant lesions and infection caused by high-risk genotypes of human papillomavirus in patients with suspicious cytological and colposcopy results: A prospective study

    2017-01-01

    Full Text Available Background/Aim. In patients with premalignant cervical lesions, human papillomavirus (HPV infection, at any moment, may be spontaneously eliminated, or may persist or transform cervical epithelium from a lower to a higher degree. Due to that, it is necessary to wisely select the patients who are at high risk of cancer development. The aim of the study was to establish the interdependence between a suspicious Papanicolaou (Pap test and colposcopy with the infection caused by high-risk genotypes of human papillomavirus and the presence of premalignant cervical lesions. Methods. This prospective study used cytological, colposcopy, real-time polymerase chain reaction (PCR of high-risk genotypes of human papillomavirus and histopathological analysis of cervical biopsy specimen. Out of 2,578 female patients sent to cytological analyses in Clinical Center of Montenegro, during 2012, 2013 and 2014, the study included 80 women who had to submit their biopsy specimens due to a suspicious Pap test and atypical colposcopy results. Results. In the group of 80 (3.1%; n = 80/2,578 of the selected female patients with suspicious Pap test and colposcopy, 2/3 or 56 (70% of them had cervicitis, and 1/3 or 24 (30% had cervical intraepithelial neoplasia. The most common type in cervical intraepithelial neoplasia was HPV16 in 8 female patients, ie 61.53% out of the number of infected, or 33.33% out of the total number of premalignant lesions. Conclusion. Patients with suspicious Papanicolaou test, colposcopy results and infection which is caused by high-risk HPV infection (HPV 16 in particular often have premalignant cervical lesions. In these cases, histopathological confirmation of lesions is mandatory, since it serves as a definitive diagnostic procedure.

    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.

    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

    This study was purposed to compare the clinical efficacy and adverse reactions of low-dose decitabine combined with CAG regimen (aclarubicin, Ara-C, and G-CSF) and CAG regimen alone in intermediate to high-risk myelodysplastic syndromes (MDS), and evaluate the validity and efficacy of the former regimen as new treatment method of intermediate to high-risk myelodysplastic syndromes. A total of 12 patients with intermediate (IR) to high-risk (HR) MDS treated by low-dose decitabine combined with CAG regimen and 10 patients with IR to HR MDS treated by CAG regimen alone were evaluated after treatment of 1 cycle and at least after 2 cycles. The complete remission (CR) after 1 cycle, overall remission rate (ORR), progression free survival (PFS) and overall survival (OS) between them were analyzed. The results showed that 9 patients treated by low-dose decitabine combined with CAG regimen achieved complete remission after 1 cycle, 2 patients achieved partial remission, 1 patient did not show reaction. The complete remission rate was 75.0% and overall response rate was 91.7%. The median time of disease free survival was 9 months (0-27 months). The median overall survival time was 16 months (3-28 months). 4 patients suffered from pulmonary infection after treatment and then were all cured after treatment with anti-infective therapy. The 5 patients treated by CAG regimen alone achieved complete remission,3 patients achieved partial remission, 2 patients showed non-reaction. The complete remission rate was 50.0% and overall response rate was 80.0%. The median time of disease free survival was 6 months(0-18 months). The median overall survival time was 13 months(3-31 months), 4 patients suffered from pulmonary infection, 1 patient suffered from enteric infection and 1 patient suffered from Escherichia coli septicemia after treatment, all of them becomed better after active treatment. Two groups of patients all had no serious adverse reactions, All patients could tolerate, no

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

    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. 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. 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.

We compared the impact of AKI alone and in combination with MOF on the survival of patients admitted to a large tertiary care medical intensive care unit (MICU.  Methods: We abstracted data from the electronic medical records of patients admitted to the MICU from April 2012 through June 2013 and categorized patients as either high-risk or low- risk status based on use of vasopressor support or mechanical ventilation during the ICU stay. The outcomes we considered were in-hospital, 30-day, 90-day, 180-day, and 1-year mortality. Results: Of the 834 critically ill patients, 743 (89% developed some degree of AKI. Ninety-one percent of the high-risk cohort developed AKI and 87% of the low-risk cohort developed AKI. Patients with AKI had higher mortality at 1-year than patients without AKI (adjusted odds ratio [OR], 2.5; 95% confidence interval [CI], 1.38 to 4.53; P interaction 0.0026.  Hospital mortality was greater for high-risk patients without AKI than for low-risk patients with AKI. Conclusion: Acute kidney injury occurs at similar frequency in high and low-risk ICU patients and has significant impact on survival in both groups.  Cardiovascular collapse or respiratory failure has greater impact on short term mortality than AKI, but this effect diminishes over time. Conversely, the impact of AKI on mortality increased over time and remained an independent risk factor for mortality.

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

    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.

    European studies have suggested that the esp gene and other virulence factors have roles in vancomycin-resistant Enterococcus faecium (VREfm) infections. The aim of this study was to examine the relationship between the spectrum of clinical disease and putative virulence factors in vanB VREfm isolates. A multiplex polymerase chain reaction was used to amplify potential virulence genes (asa1, gel E, cylA, esp and hyl) in VREfm isolates obtained from an Australian population of haematology patients. Clonality was assessed by pulsed-field gel electrophoresis (PFGE) and automated ribotyping. Infection, requirement for intensive care unit (ICU) admission and all-cause 30-day mortality were used as clinical indicators of organism virulence. Forty-one VREfm vanB isolates (41 patients; 14 infected and 27 colonised only) were analysed. Thirty-five of these isolates were typed by PFGE, 31 of which were represented by three clusters. The esp gene was identified in 22 of 27 (81.5%) screening and 11 of 14 (78.6%) infection-associated isolates. One isolate was hyl gene positive, and no isolate contained asa1, gel E or cylA genes. VREfm infection was independently associated with host factors (underlying diagnosis of acute myeloid leukaemia, age esp gene. ICU admission was negatively associated with presence of the esp gene (OR: 0.05; 95% CI: 0.01-0.61; P=0.02). There was no association between 30-day mortality and host factors or the presence of the esp gene. When compared to European and US reports, a high esp gene prevalence and low hyl gene prevalence was observed in polyclonal VRE isolates obtained from this immunocompromised population.

    Addition of etoposide to the R-CHOP chemotherapy regimen with cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab (R-CHOEP) has resulted in improved survival in young patients with high-risk diffuse large B-cell lymphoma (DLBCL). It is not known whether biological factors can predict this effect. In this study, 245 patients representing all young patients with high-risk DLBCL treated with R-CHOP or R-CHOEP in 2004-2012 in Denmark were extracted from the Danish lymphoma database. Patients were stratified according to cell of origin (COO) into germinal-center B-cell-like (GCB) or non-GCB by Hans' algorithm. Only in patients with the GCB phenotype was treatment with R-CHOEP associated with improved progression-free survival (PFS) and overall survival (OS) compared with R-CHOP. Patients with GCB phenotype treated with R-CHOEP also had superior OS compared with patients with non-GCB phenotype treated with R-CHOEP. This was not seen in R-CHOP treated patients. This could suggest that R-CHOEP should be restricted to patients with GCB phenotype.

    Aim: This study aimed to compare the efficacy and safety between standard and low-dose tirofiban in the treatment of elderly high-risk non-ST-segment elevation acute coronary syndrome (NSTE-ACS) patients who underwent percutaneous coronary intervention (PCI).Methods: Ninety-four very elderly (≥80 years) high-risk patients with NSTE-ACS were randomly assigned to the standard myocardial infarction (TIMI) grade flow were assessed. The major adverse cardiac events (MACEs), including death, myocardial infarction, recurrent angina and urgent target-vessel revascularization (TVR), were documented at 7 d, 30 d, and 6 months, and bleeding events were recorded at 7 d.Results: Although a significantly higher inhibition of platelet aggregation was observed in the standard-dose group (P0.05). The rate of MACEs was not significantly different at 7 days (2.1% vs 4.4%, P=0.61), 30 days(6.3% vs 8.7%, P=0.71) and 6 months (14.6% vs 17.4%, P=0.71). Major bleeding events were significantly higher in the standard-dose group (10.4% vs 0.0%, P=0.03).Conclusion: In very elderly high-risk patients with NSTE-ACS undergoing PCI, low-dose tirofiban offered about the same level of protection from major ischemic events that standard doses did, with less associated bleeding.

    Peramivir, the only injectable anti-influenza neuraminidase inhibitor medically available in Japan at present, is considered first-line treatment in patients with high risk factors for influenza exacerbation. We conducted a drug-use investigation of peramivir in inpatients with high risk factors (old age, pregnancy, and underlying disease such as chronic respiratory disease) from January 2010 to March 2013. Data of 772 patients from 124 facilities across Japan were collected; peramivir's safety in 770 patients and effectiveness in 688 patients were examined. In total, 412 adverse events were observed in 219 patients (28.4%). Of these, 155 events were adverse drug reactions (ADRs) observed in 98 patients (12.7%). Major ADRs (≥2%) were increased aspartate aminotransferase (5.1%), increased alanine aminotransferase (3.8%) and decreased white blood cell count (2.5%). Fourteen serious ADRs were observed in 12 patients (1.6%). All serious ADRs were resolved or improved except for two events for which outcomes were unknown. Multivariate analyses revealed that ADR incidences were significantly associated with these four backgrounds of patients: medical history, no influenza vaccination, renal impairment and other infection(s). With regard to its effectiveness, the median time to alleviation of both influenza symptoms and fever was 3 days, including the first day of administration, which was the same as in other previous surveillance studies. This surveillance study indicated the safety of peramivir in the treatment of influenza inpatients with high risk factors under routine clinical settings. Copyright © 2016 The Authors.

    Full Text Available Abstract Background To assess the influence of sentinel lymph nodes (SNs SPECT/CT and 18 F-choline (18 F-FCH PET/CT in radiotherapy (RT treatment planning for prostate cancer patients with a high-risk for lymph node (LN involvement. Methods Twenty high-risk prostate cancer patients underwent a pelvic SPECT acquisition following a transrectal ultrasound guided injection of 99mTc-Nanocoll into the prostate. In all patients but one an 18 F-FCH PET/CT for RT treatment planning was performed. SPECT studies were coregistered with the respective abdominal CTs. Pelvic SNs localized on SPECT/CT and LN metastases detected by 18 F-FCH PET/CT were compared to standard pelvic clinical target volumes (CTV. Results A total of 104 pelvic SNs were identified on SPECT/CT (mean 5.2 SNs/patient; range 1–10. Twenty-seven SNs were located outside the standard pelvic CTV, 17 in the proximal common iliac and retroperitoneal regions above S1, 9 in the pararectal fat and 1 in the inguinal region. SPECT/CT succeeded to optimize the definition of the CTV and treatment plans in 6/20 patients due to the presence of pararectal SNs located outside the standard treatment volume. 18 F-FCH PET/CT identified abnormal tracer uptake in the iliac LN region in 2/19 patients. These abnormal LNs were negative on SPECT/CT suggesting a potential blockade of lymphatic drainage by metastatic LNs with a high tumour burden. Conclusions Multimodality imaging which combines SPECT/CT prostate lymphoscintigraphy and 18 F-FCH PET/CT identified SNs outside standard pelvic CTVs or highly suspicious pelvic LNs in 40% of high-risk prostate cancer patients, highlighting the potential impact of this approach in RT treatment planning.

    The aim of this study was to investigate the prevalence of colorectal neoplasms in patients coronary artery disease (CAD) with or without a family history of colorectal cancer (CRC). In this cross-sectional study, individuals with suspected CAD in the absence of cancer-related symptoms underwent coronary angiography for the first time, and were divided into CAD and non-CAD groups. Colonoscopy was performed in individuals at high-risk tier based on their Asia-Pacific colorectal screening (APCS) score. Their waist circumference (WC), height and body weight were measured. There were 634 of 1157 individuals at a high risk of developing advanced colorectal neoplasms, 91.0% (577/634) of whom were male smokers. The proportion of CAD patients in the high-risk tier was 81.5% (517/634), while the prevalences of adenomas (32.1% vs 22.2%, P prevalence of adenomas was still significantly higher in the CAD group than in the non-CAD group (25.5% vs 16.0%, P colorectal neoplasms classified by the APCS score still showed a remarkably high prevalence of colorectal adenomas. Moreover, the association between the occurrence of adenomas and CAD was stronger in overweight (BMI ≥ 25 kg/m(2)) individuals. © 2015 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

    The aim of this study was to assess whether lymphovascular space invasion (LVSI) and nodal status provide adequate prognostic information in comparison with the entire set of traditional prognostic factors in intermediate- and high-risk endometrial cancer patients treated and staged with primary surgery and adjuvant radiotherapy. Three hundred twenty-four previously untreated high-intermediate- and high-risk endometrial cancer patients with FIGO (International Federation of Gynecology and Obstetrics) stage I to IIIC; endometrioid, serous, or clear cell histology; diagnosed between November 1995 and December 2006; who presented to Peter MacCallum Cancer Centre for adjuvant radiotherapy were included in these analyses. All traditionally recognized prognostic factors and newly created 4 pairs of combination of LVSI and nodal status were studied with respect to survival and patterns of failure. The median follow-up time was 4.8 years. Five-year failure-free survival for all patients according to FIGO stage I, II, and III were 87.4%, 89.0%, and 62.4 %, respectively. In multivariable analysis for relapse, positive LVSI had a hazard ratio of 4.9 (P = 0.000), which increased to 8.8 (P = 0.004) in the presence of positive nodes. For overall survival, only LVSI was significant, with a hazard ratio of 3.02 (P = 0.003). In particular, in the presence of LVSI and nodes, histological type, grade, and myometrial invasion were not significant prognosticators for relapse or overall survival. This model enables the separation of good prognosis patients even among poorly differentiated endometrioid, serous, and clear cell carcinoma patients and can be used in simplifying the staging of endometrial cancer and for selecting patients for high-risk endometrial cancer studies.

    Although hyperthermic intraperitoneal chemotherapy (HIPEC) has been extensively used to treat patients with peritoneal metastases (PM) from colorectal cancer (CRC), a standard protocol has not yet been established. The aim of this preliminary clinical study was to confirm in vitro the efficacy of mitomycin C combined with 5-fluorouracil (MMC-5FU) under hyperthermic conditions in CRC and investigate the pharmacokinetics and feasibility of HIPEC with MMC-5FU for patients at high risk of PM from CRC. To simulate HIPEC in vitro, we used the collagen gel droplet-embedded culture drug sensitivity test with the HCT166 colorectal cell line to assess the antitumor efficacy of MMC and 5FU as single-agent and combination treatments following incubation with HCT116 cells for 30 min at either 37 or 42°C. In addition, five patients at high risk of PM from CRC underwent surgical tumor resection followed by HIPEC with MMC-5FU. Our results demonstrated that the combined administration of MMC-5FU suppressed tumor cell proliferation more efficiently compared to either agent used alone. In addition, hyperthermia at 42°C significantly enhanced drug sensitivity. During the clinical application of HIPEC with MMC-5FU, no grade 4 hematological toxicities or surgical adverse events were recorded. In addition, there was no evidence of peritoneal recurrence during a median observational period of 38 months. Of note, two patients with positive intraoperative peritoneal cytology at the first surgery developed no peritoneal recurrence and exhibited negative peritoneal cytology at the second surgery. In conclusion, HIPEC using MMC-5FU was shown to be a feasible therapeutic option, with an acceptable toxicity profile, for patients at high risk of PM from CRC. Therefore, HIPEC with MMC-5FU may be a promising novel therapeutic option for such patients, which merits further verification of its safety and efficacy in large-scale clinical trials.

    Peanut allergy is a major public health problem that affects 1% of the population and has no effective therapy. To examine the safety and efficacy of oral desensitization in peanut-allergic children in combination with a brief course of anti-IgE mAb (omalizumab [Xolair]). We performed oral peanut desensitization in peanut-allergic children at high risk for developing significant peanut-induced allergic reactions. Omalizumab was administered before and during oral peanut desensitization. We enrolled 13 children (median age, 10 years), with a median peanut-specific IgE level of 229 kU(A)/L and a median total serum IgE level of 621 kU/L, who failed an initial double-blind placebo-controlled food challenge at peanut flour doses of 100 mg or less. After pretreatment with omalizumab, all 13 subjects tolerated the initial 11 desensitization doses given on the first day, including the maximum dose of 500 mg peanut flour (cumulative dose, 992 mg, equivalent to >2 peanuts), requiring minimal or no rescue therapy. Twelve subjects then reached the maximum maintenance dose of 4000 mg peanut flour per day in a median time of 8 weeks, at which point omalizumab was discontinued. All 12 subjects continued on 4000 mg peanut flour per day and subsequently tolerated a challenge with 8000 mg peanut flour (equivalent to about 20 peanuts), or 160 to 400 times the dose tolerated before desensitization. During the study, 6 of the 13 subjects experienced mild or no allergic reactions, 5 subjects had grade 2 reactions, and 2 subjects had grade 3 reactions, all of which responded rapidly to treatment. Among children with high-risk peanut allergy, treatment with omalizumab may facilitate rapid oral desensitization and qualitatively improve the desensitization process.

  5. INVASIVE CANDIDA INFECTIONS IN PATIENTS WITH HAEMATOLOGICAL MALIGNANCIES AND HEMATOPOIETIC STEM CELL TRANSPLANT RECIPIENTS: CURRENT EPIDEMIOLOGY AND THERAPEUTIC OPTIONS.

    Directory of Open Access Journals (Sweden)

    Corrado Girmenia

    2011-03-01

    Full Text Available In the last decades, the global epidemiological impact of invasive candidiasis (IC in patients with hematologic malignancies (HM and in hematopoietic stem cell transplant (HSCT recipients has decreased and the incidence of invasive aspergillosis  exceeded that of Candida infections. The use of prevention strategies, first of all antifungal prophylaxis with triazoles,  contributed to the reduction of IC in these populations as demonstrated by several  epidemiological studies. However, relatively little is known about the current epidemiological patterns of IC in HM and HSCT populations, because recent epidemiological data almost exclusively derive from retrospective experiences and few prospective data are available. Several prospective, controlled studies in the prophylaxis of invasive fungal diseases have been conducted in both the HM and HSCT setting. On the contrary, most of the prospective controlled trials that demonstrated the efficacy of the antifungal drugs echinocandins and voriconazole in the treatment of candidemia and invasive candidiasis mainly involved  patients with underlying conditions other than HM or  HSCT.  For these reasons, international guidelines provided specific indications for the prophylaxis strategies in HM and HSCT patients, whereas the  recommendations on therapy of documented Candida infections are based on the results observed in the general population and should be considered with caution.

    Objectives Animal studies have demonstrated a role for substance P binding to neurokinin-1 receptor in the pathogenesis of acute pancreatitis. Our aim was to assess the efficacy of a neurokinin-1 receptor antagonist (aprepitant) at preventing post-ERCP pancreatitis in high risk patients. Methods Randomized, double-blind, placebo controlled trial at a single academic medical center. Patients at high risk for post-ERCP pancreatitis received either placebo or oral aprepitant administered 4 hours prior to ERCP, 80 mg 24 hours after the first dose, and then 80 mg 24 hours after the second dose. Fisher's exact test was used to compare incidence of post-ERCP pancreatitis in the two groups. Results 34 patients received aprepitant and 39 patients received placebo. Baseline characteristics were similar between the two groups. Incidence of acute pancreatitis was 7 in the aprepitant group and 7 in the placebo group. Hospitalization within 7 days post-procedure for abdominal pain that did not meet criteria for acute pancreatitis occurred in 6 and 9 patients in the aprepitant and placebo groups respectively (p=0.77). Conclusions Aprepitant did not lower incidence of post-ERCP pancreatitis in this preliminary human study. Larger studies potentially using the recently available intravenous formulation are necessary to conclusively clarify the efficacy of aprepitant in this setting. PMID:22964958

    Recent studies indicate that high-risk breast cancer patients (ie, women who carry mutations in BRCA1/2 genes) who opt for contralateral prophylactic mastectomy (CPM) have a substantially reduced risk of developing contralateral breast cancer. However, the immediate and long-term impact of this decision on women's quality of life and psychosocial functioning is largely unknown. In this study, we compared the impact of BRCA1/2 genetic test result and CPM on these outcomes among newly diagnosed breast cancer patients who opted for CPM at the time of their definitive surgical treatment versus patients who did not. Participants were 149 high-risk women who underwent genetic counseling and testing for alterations in the BRCA1/2 genes. We measured self-reported quality of life, cancer-specific distress, and genetic testing-specific distress using standardized instruments before receipt of genetic test results and again 1 and 12 months later. Compared with patients who chose breast conservation or unilateral mastectomy, those who chose mastectomy of the affected breast and CPM of the unaffected breast did not report diminished quality of life or elevated distress. With respect to quality of life and distress, patients who choose CPM fare as well as those who do not in the first year after surgery.
