    The coexistence of acute myeloid leukemia and chronic lymphocytic leukemia in the same patient is rare. The majority of the cases correspond to patients that developed acute leukemia during the evolutionary course of a chronic lymphatic leukemia following treatment with chemotherapy drugs. We report a case of acute myelomonocytic leukemia concurrent with untreated B-cell chronic lymphocytic leukemia in which the use of flow cytometry analysis with a large panel of monoclonal antibodies, allowed the demonstration of different pathological populations and determine immunophenotyping patterns. Published cases of simultaneous chronic lymphocytic leukemia and acute leukemia are reviewed. The use of multiparametric flow cytometry to differentiate the populations demonstrates the utility of this technology in the diagnosis of these hematological malignancies.

    Anaplastic lymphoma receptor tyrosine kinase (ALK) is located on chromosome 2p23; the chromosomal rearrangements of this gene are common genetic alterations, resulting in the creation of multiple fusion genes involved in tumorigenesis. However, the presence of an ALK fusion in myeloid malignancies is extremely rare. We report a case of acute myelomonocytic leukemia in a 31-year-old woman with an unusual rearrangement between RAN-binding protein 2 (RANBP2) and ALK and a karyotype of 45,XX,inv(2)(p23q21),-7[20]. We detected an ALK rearrangement using fluorescence in situ hybridization, identified the ALK fusion partner by using RNA transcriptome sequencing, and demonstrated the RANBP2-ALK fusion transcript by reverse transcriptase--PCR and Sanger sequencing. Immunohistochemistry for ALK showed strong staining of the nuclear membrane in leukemic cells. The patient had an unfavorable clinical course. Our results, together with a literature review, suggest the RANBP2-ALK fusion combined with monosomy 7 may be related to a unique clonal hematologic disorder of childhood and adolescence, characterized by myelomonocytic leukemia and a poor prognosis.

    CMML (chronic myelomonocytic leukemia) belongs to the group of myeloid neoplasms known as myelodysplastic and myeloproliferative diseases. In some patients with a history of CMML, the disease transforms to acute myelomonocytic leukemia (AMML). There are no specific treatment options for patients suffering from CMML except for supportive care and DNA methyltransferase inhibitors in patients with advanced disease. New treatment strategies are urgently required, so we have investigated the use of immunotherapeutic directed cytolytic fusion proteins (CFPs), which are chimeric proteins comprising a selective domain and a toxic component (preferably of human origin to avoid immunogenicity). The human serine protease granzyme B is a prominent candidate for tumor immunotherapy because it is expressed in cytotoxic T lymphocytes and natural killer cells. Here, we report the use of CD64 as a novel target for specific CMML and AMML therapy, and correlate CD64 expression with typical surface markers representing these diseases. We demonstrate that CD64-specific human CFPs kill CMML and AMML cells ex vivo, and that the mutant granzyme B protein R201K is more cytotoxic than the wild-type enzyme in the presence of the granzyme B inhibitor PI9. Besides, the human CFP based on the granzyme B mutant was also able to kill AMML or CMML probes resistant to Pseudomonas exotoxin A.

    A 2-year-old, spayed female domestic shorthair cat was referred with a history of anorexia and depression of 1 week duration. On physical examination, the cat was lethargic and febrile, with splenomegaly, anisocoria and ulcerative stomatitis. A complete blood count (CBC) and a biochemistry profile showed leukocytosis, numerous blast cells in the peripheral blood, thrombocytopenia, hyperglobulinaemia and a positive test for feline leukaemia virus antigen. A diagnosis of acute myelomonocytic leukaemia was made on the basis of the results of bone marrow cytology, histopathology, and immunochemistry (CD3, CD79a, lysozyme, and myeloperoxidase) tests. Following an unexpected 1-month period of clinical and clinicopathological remission without chemotherapy, the cat relapsed and died 1 week later.

    Despite its rarity, donor cell leukemia (DCL) is a most intriguing entity. We report here the case of a 5 year-old girl with juvenile myelomonocytic leukemia and normal female karyotype who developed acute myeloblastic leukemia with a karyotype of 46, X, t(X; 7) (p21; p11.2), der(7) t(3; 7) (q13.3; q22) 5 months after peripheral blood hematopoietic stem cell transplantation from her HLA-matched sister. We performed the analysis of short tandem repeat sequence markers to DNA obtained from donor peripheral blood, patient's peripheral blood including leukemic blasts and patient's hair root. This analysis showed that the leukemic blood DNA matched the donor blood DNA and not the patient's DNA, thus confirming DCL. To our knowledge, this is the first case of DCL after peripheral blood SCT for juvenile myelomonocytic leukemia.

    Extensive nuclear convolution and lobulation was found in the peripheral blood cells of a patient with acute leukemia. While the morphology of the cells, such as observed with the light microscope, was compatible with the diagnosis of acute myeloid leukemia, the finding of Sezary-like cells with the electron microscope helped to establish the diagnosis of acute myelomonocytic leukemia. This report emphasizes the importance of the electron microscope for the correct diagnosis of leukemias.

    This paper presents a summary of the evidence review group (ERG) report into the clinical effectiveness and cost-effectiveness of azacitidine (aza) compared with conventional care regimes (CCR) for higher risk patients with myelodysplastic syndrome (MDS), chronic myelomonocytic leukaemia (CMML) and acute myeloid leukaemia (AML), based on the evidence submission from the manufacturer to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal process. The patient outcomes governing relative effectiveness and cost-effectiveness were defined as overall survival, time to progression (TTP) to AML, adverse events and health-related quality of life (HRQoL). The clinical evidence was derived from an open-label randomised controlled trial referred to as study AZA-001. It compared aza with CCR in 358 patients with higher risk MDS, CMML and AML 20-30% blasts. The outcomes reported in AZA-001 included overall survival, TTP to AML and adverse events. No HRQoL results were reported; however, outcomes likely to impact on HRQoL were provided. The results showed that: the median overall survival was 24.5 months on aza, compared with 15.0 months in the CCR group (p = 0.0001); the response rates were low (complete remission 17% aza versus 8% CCR); the median time to transformation to AML was greater in the aza group (17.8 versus 11.5 months; p < 0.0001); and of patients who were red blood cell (RBC) transfusion-dependent at baseline, 45% of those on aza became RBC transfusion-independent during the treatment period, compared with 11.8% in the CCR group (p < 0.0001). The ERG reran the submission's search strategies after some modifications incorporating minor improvements. The ERG analysed the submitted economic model (model 1) and identified a number of inconsistencies and errors within the model. The manufacturer submitted a revised model for analysis by the ERG. Using the issues identified in the earlier analysis, the ERG conducted

    The reciprocal translocation (9;22)(q34;q11) is highly characteristic of chronic myeloid leukemia (CML) and the pericentric inversion inv(16)(p13q22) is almost only found in acute nonlymphocytic leukemia of the myelomonocytic subtype (ANLL M4). Only twice before have an inv(16) and a t(9;22) been found in the same cells, and both times the patients seemed to have de novo ANLL M4. We describe the case of a 21-year-old man who in July 1986 presented with a clinically and hematologically classic chronic phase CML. Treatment with busulfan led to no improvement; instead in September 1986 he developed blast crisis with ANLL M4Eo morphology. He was now cytogenetically examined and the karyotype 45,X,-Y,t(9;22)(q34;q11),inv(16)(p13q22) was found. Southern blot analysis of the bone marrow DNA sampled at this time revealed a standard rearrangement in the 3' end of the M-bcr. Intensive cytostatic treatment caused cytopenia followed by complete hematologic, clinical, and cytogenetic reversal to chronic phase CML, so that in January 1987 the bone marrow karyotype was 46,XY,t(9;22)(q34;q11). Persistent splenomegaly was treated with splenectomy, and a chloroma of the skin was removed by irradiation. In March 1987 he received an allogeneic bone marrow transplant. Since then his only medical problem has been mild graft-versus-host disease; he is well and is working full time as a blacksmith.

    PubMed Central

    2014-01-01

    The FIP1L1-PDGFRA rearrangement results in constitutive activation of the tyrosine kinase PDGFRA. Neoplasms harboring this rearrangement are responsive to imatinib mesylate at doses much lower than those recommended for the treatment of chronic myelogenous leukemia. Only a single report has described the identification of FIP1L1-PDGFRA in chronic myelomonocytic leukemia (CMML). Herein, we present a case report of a patient in whom the FIP1L1-PDGFRA was discovered as he evolved from CMML to acute myeloid leukemia (AML). The presence of a dominant neoplastic clone with FIP1L1-PDGFRA rearrangement was suspected on the basis of sudden onset of peripheral and bone marrow eosinophilia and confirmed by fluorescence in situ hybridization and molecular diagnostic tests. Whereas the patient was initially refractory to chemotherapy before the rearrangement was detected, subsequent therapy with imatinib led to complete remission. PMID:24669761

    Seventy-eight adult patients with acute leukaemia were classified cytologically into 3 categories: acute lymphoblastic leukaemia (ALL), acute myelogenous leukaemia (AML) or acute undifferentiated leukaemia (AUL). The periodic acid-Schiff stain was of little value in differentiating the 3 groups. The treatment response in each group was different: 94% of patients with ALL (16/17) achieved complete remission with prednisone, vincristine and other drugs in standard use in childhood ALL; 59% of patients with AML (27/46) achieved complete remission with cytosine arabinoside and daunorubicin (22 patients), or 6-thioguanine and cyclophosphamide (2 patients), 6-thioguanine, cyclophosphamide and Adriamycin (1 patient), and cytosine and Adriamycin (1 patient); only 2 out of 14 patients (14%) with acute undifferentiated leukaemia achieved complete remission using cytosine and daunorubicin after an initial trial of prednisone and vincristine had failed. Prednisone and vincristine would seem to be of no value in acute undifferentiated leukaemia. It would seem also that no benefit is obtained by classifying all patients with acute leukaemia over 20 years of age as “adult acute leukaemia” and treating them with the same polypharmaceutical regimen. The problems posed by each disease are different and such a policy serves only to obscure them. ImagesFig. 1Fig. 2Fig. 3 PMID:4141625

    Introduction An estimated 4.6 billion cases of diarrhoea occurred worldwide in 2004, resulting in 2.2 million deaths. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for acute diarrhoea in adults living in resource-rich countries? What are the effects of treatments for acute mild-to-moderate diarrhoea in adults from resource-rich countries travelling to resource-poor countries? What are the effects of treatments for acute mild-to-moderate diarrhoea in adults living in resource-poor countries? What are the effects of treatments for acute severe diarrhoea in adults living in resource-poor countries? We searched: Medline, Embase, The Cochrane Library, and other important databases up to January 2010 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 72 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics, antimotility agents, antisecretory agents, bismuth subsalicylate, diet, intravenous rehydration, nasogastric tube rehydration, oral rehydration solutions (amino acid oral rehydration solution, bicarbonate oral rehydration solution, reduced osmolarity oral rehydration solution, rice-based oral rehydration solution, standard oral rehydration solution), vitamin A supplementation, and zinc supplementation.

    ENMD-2076 is a novel, orally-active molecule that inhibits Aurora A kinase, as well as c-Kit, FLT3 and VEGFR2. A phase I study was conducted to determine the maximum tolerated dose (MTD), recommended phase 2 dose (RP2D) and toxicities of ENMD-2076 in patients with acute myeloid leukemia (AML) and chronic myelomonocytic leukemia (CMML). Patients received escalating doses of ENMD-2076 administered orally daily [225 mg (n = 7), 375 mg (n = 6), 325 mg (n = 9), or 275 mg (n = 5)]. Twenty-seven patients were treated (26 AML; 1 CMML-2). The most common non-hematological toxicities of any grade, regardless of association with drug, were fatigue, diarrhea, dysphonia, dyspnea, hypertension, constipation, and abdominal pain. Dose-limiting toxicities (DLTs) consisted of grade 3 fatigue, grade 3 typhilitis, grade 3 syncope and grade 3 QTc prolongation). Of the 16 evaluable patients, one patient achieved a complete remission with incomplete count recovery (CRi), three experienced a morphologic leukemia-free state (MLFS) with a major hematologic improvement in platelets (HI-P), and 5 other patients had a reduction in marrow blast percentage (i.e. 11-65 %). The RP2D in this patient population is 225 mg orally once daily.

    Familial platelet disorder with a propensity to develop acute myeloid leukemia (FPD/AML) is a rare autosomal dominant disease characterized by thrombocytopenia, abnormal platelet function, and a propensity to develop myelodysplastic syndrome (MDS) and AML. So far, > 20 affected families have been reported. Recently, a second RUNX1 alteration has been reported; however, no additional molecular abnormalities have been found so far. We identified an acquired CBL mutation and 11q-acquired uniparental disomy (11q-aUPD) in a patient with chronic myelomonocytic leukemia (CMML) secondary to FPD with RUNX1 mutation but not in the same patient during refractory cytopenia. This finding suggests that alterations of the CBL gene and RUNX1 gene may cooperate in the pathogenesis of CMML in patients with FPD/AML. The presence of CBL mutations and 11q-aUPD was an important "second hit" that could be an indicator of leukemic transformation of MDS or AML in patients with FPD/AML.

    A 58-year-old man was admitted with symptoms of lethargy and easy bruising for four months duration. Peripheral blood (PB) analysis revealed a white blood cell count (WBC) of 15.9 x 10(9)/l with monocytes 5.4 x 10(9)/l. Bone marrow (BM) was hypercellular with 15% blasts, monocytosis and trilineage dysplasia. Conventional cytogenetic analysis (G-banding) detected an apparently normal male karyotype (46,XY). A diagnosis of chronic myelomonocytic leukaemia (CMML) was made. After 3 years, PB analysis revealed a WBC count of 22 x 10(9)/l and a predominance of blasts. BM aspirate analysis also revealed 89% myeloid blasts and G-banding detected the emergence of an abnormal clone harbouring an extra copy of chromosomes 13 and 15. A diagnosis of disease transformation to acute myeloid leukaemia (AML) was made. Post chemotherapy BM aspirate was very hypocellular and the abnormal +13, +15 clone was still present suggesting primary refractory disease. A second course of chemotherapy was only administered for 24 hours due to complications. The abnormal +13, +15 clone was still present and it was decided that no further treatment apart from palliative care could be offered. The patient died 11 weeks later, five months after AML transformation. This is the first description of a cytogenetically normal CMML patient transforming to AML with the emergence of a unique +13, +15 double trisomy resulting in an adverse outcome.

    Purpose: The PARP inhibitor veliparib delays DNA repair and potentiates cytotoxicity of multiple classes of chemotherapy drugs, including topoisomerase I inhibitors and platinating agents. This study evaluated veliparib incorporation into leukemia induction therapy using a previously described topotecan/carboplatin backbone.Experimental Design: Employing a 3+3 trial design, we administered escalating doses of veliparib combined with topotecan + carboplatin in relapsed or refractory acute leukemias, aggressive myeloproliferative neoplasms (MPN), and chronic myelomonocytic leukemia (CMML).Results: A total of 99 patients received veliparib 10-100 mg orally twice daily on days 1-8, 1-14, or 1-21 along with continuous infusion topotecan 1.0-1.2 mg/m(2)/d + carboplatin 120-150 mg/m(2)/d on days 3-7. The MTD was veliparib 80 mg twice daily for up to 21 days with topotecan 1.2 mg/m(2)/d + carboplatin 150 mg/m(2)/d. Mucositis was dose limiting and correlated with high veliparib concentrations. The response rate was 33% overall (33/99: 14 CR, 11 CRi, 8 PR) but was 64% (14/22) for patients with antecedent or associated aggressive MPNs or CMML. Leukemias with baseline DNA repair defects, as evidenced by impaired DNA damage-induced FANCD2 monoubiquitination, had improved survival [HR = 0.56 (95% confidence interval, 0.27-0.92)]. A single 80-mg dose of veliparib, as well as veliparib in combination with topotecan + carboplatin, induced DNA damage as manifested by histone H2AX phosphorylation in CD34(+) leukemia cells, with greater phosphorylation in cells from responders.Conclusions: The veliparib/topotecan/carboplatin combination warrants further investigation, particularly in patients with aggressive MPNs, CMML, and MPN- or CMML-related acute leukemias.

    Double minute chromosomes (dmin) are small, paired chromatin bodies that lack a centromere and represent a form of extrachromosomal gene amplification. Dmin are rare in myeloid neoplasms and are generally associated with a poor prognosis. Most studies of dmin in myeloid neoplasms are case reports or small series. In the current study, we present the clinicopathologic and cytogenetic features of 22 patients with myeloid neoplasms harboring dmin. These neoplasms included acute myeloid leukemia (AML) (n = 18), myelodysplastic syndrome (MDS) (n = 3), and chronic myelomonocytic leukemia (CMML) (n = 1). The AML cases consisted of AML with myelodysplasia-related changes (n = 13) and therapy-related AML (n = 5). Dmin were detected in initial pre-therapy samples in 14 patients with AML or CMML; they were acquired during the disease course in 8 patients who had AML or MDS. The presence of dmin was associated with micronuclei (18/18; 100%), complex karyotype (17/22; 77.3%), and amplification of MYC (12/16; 75%) or MLL (4/16; 25%). Immunohistochemical staining for MYC performed on bone marrow core biopsy or clot sections revealed increased MYC protein in all 19 cases tested. Except for one patient, most patients failed to respond to risk-adapted chemotherapies. At last follow up, all patients had died of disease after a median of 5 months following dmin detection. In conclusion, dmin in myeloid neoplasms commonly harbor MYC or MLL gene amplification and manifest as micronuclei within leukemic blasts. Dmin are often associated with myelodysplasia or therapy-related disease, and complex karyotypes.

    Background The prognostic value of cytogenetic findings in chronic myelomonocytic leukemia is unclear. Our purpose was to evaluate the independent prognostic impact of cytogenetic abnormalities in a large series of patients with chronic myelomonocytic leukemia included in the database of the Spanish Registry of Myelodysplastic Syndromes. Design and Methods We studied 414 patients with chronic myelomonocytic leukemia according to WHO criteria and with a successful conventional cytogenetic analysis at diagnosis. Different patient and disease characteristics were examined by univariate and multivariate methods to establish their relationship with overall survival and evolution to acute myeloid leukemia. Results Patients with abnormal karyotype (110 patients, 27%) had poorer overall survival (P=0.001) and higher risk of acute myeloid leukemia evolution (P=0.010). Based on outcome analysis, three cytogenetic risk categories were identified: low risk (normal karyotype or loss of Y chromosome as a single anomaly), high risk (presence of trisomy 8 or abnormalities of chromosome 7, or complex karyotype), and intermediate risk (all other abnormalities). Overall survival at five years for patients in the low, intermediate, and high risk cytogenetic categories was 35%, 26%, and 4%, respectively (P<0.001). Multivariate analysis confirmed that this new CMML-specific cytogenetic risk stratification was an independent prognostic variable for overall survival (P=0.001). Additionally, patients belonging to the high-risk cytogenetic category also had a higher risk of acute myeloid leukemia evolution on univariate (P=0.001) but not multivariate analysis. Conclusions Cytogenetic findings have a strong prognostic impact in patients with chronic myelomonocytic leukemia. PMID:21109693

    Central diabetes insipidus (DI) is well-documented as a presenting feature of myelodysplastic syndrome and acute myeloid leukemia in adults. However, DI is unusual in pediatric patients with myeloid malignancies. We report here this rare complication in a child with neurofibromatosis type 1 who developed juvenile myelomonocytic leukemia and monosomy 7. Our case and previously reported cases of DI arising as a complication in myeloid malignancies demonstrate a close association with deletion of chromosome 7. The clinical characteristics and outcomes of these uncommon cases in children are reviewed and discussed.

    In pediatric acute myeloid leukemia (AML), chromosomal abnormalities leading to a disruption of the lysine methyltransferase 2A (KMT2A) gene in 11q23 are the most frequent rearrangements. Here, we report on the identification of a novel cryptic insertion, ins(11;X)(q23;q28q12), resulting in a translocation of the KMT2A gene in 11q23, leading to a KMT2A-FLNA fusion in a 13-month-old boy with de novo acute myelomonocytic leukemia, who died 38 days after diagnosis. The patient presented a complex karyotype 48∼49,Y,del(X)(q12),+del(X)(q12),+8,ins(11;X)(q23; q28q12),+19. The identified fusion gene was predicted to be out-of-frame (fusion of portions of KMT2A exon 11 with FLNA exon 11). However, RT-PCR experiments demonstrated that a potentially functional transcript was generated by alternative splicing where KMT2A exon 10 was spliced in-frame to the truncated FLNA exon 11. This case report helps to better understand the rare but potentially severe impact of KMT2A- FLNA fusions in infants with AML to improve prognostic stratification of therapy and clinical management.

    Juvenile myelomonocytic leukemia (JMML) is a myeloproliferative neoplasm (MPN) of childhood with a poor prognosis. Mutations in NF1, NRAS, KRAS, PTPN11 and CBL occur in 85% of patients, yet there are currently no risk stratification algorithms capable of predicting which patients will be refractory to conventional treatment and therefore be candidates for experimental therapies. In addition, there have been few other molecular pathways identified aside from the Ras/MAPK pathway to serve as the basis for such novel therapeutic strategies. We therefore sought to genomically characterize serial samples from patients at diagnosis through relapse and transformation to acute myeloid leukemia in order to expand our knowledge of the mutational spectrum in JMML. We identified recurrent mutations in genes involved in signal transduction, gene splicing, the polycomb repressive complex 2 (PRC2) and transcription. Importantly, the number of somatic alterations present at diagnosis appears to be the major determinant of outcome. PMID:26457647

    We have studied 73 adults with acute diarrhoea and identified a micro-organism or toxin likely to be the cause in 58%. In addition to routinely cultured bacteria, Campylobacter coli/jejuni and Clostridium difficile were important pathogens in the community. Patients who developed diarrhoea after antibiotic use had a distinctive clinical syndrome and comprised the third largest group of cases. Clinical, epidemiological, and histological features in an additional group with negative cultures and no antibiotic history suggest that an additional bacterial pathogen remains to be identified as a cause of acute diarrhoea in adults.

    All asthma patients are at risk for acute asthma exacerbations. Moderate to severe exacerbations account for many emergency department visits and subsequent hospitalizations each year. Recent studies have advanced our understanding of the pathogenesis and treatment of acute asthma. The purpose of this review is to provide practical guidance in the assessment and treatment of adults with acute asthma in the hospital setting. Managing patients with acute asthma involves assessing the severity of the exacerbation, implementing measures to rapidly reverse airflow limitation, and instituting therapies that limit the progression of airway inflammation. Some patients may benefit from other supportive measures such as heliox and noninvasive ventilation. If the patient continues to deteriorate and requires mechanical ventilation, then ventilator settings that minimize the risk of hyperinflation should be chosen. After an episode of acute asthma, long-term preventive medications, especially inhaled corticosteroids, should be prescribed and education should be provided to prevent future episodes.

  10. Acute Monoarthritis: Diagnosis in Adults.

    Acute monoarthritis can be the initial manifestation of many joint disorders. The most common diagnoses in the primary care setting are osteoarthritis, gout, and trauma. It is important to understand the prevalence of specific etiologies and to use the appropriate diagnostic modalities. A delay in diagnosis and treatment, particularly in septic arthritis, can have catastrophic results including sepsis, bacteremia, joint destruction, or death. The history and physical examination can help guide the use of laboratory and imaging studies. The presence of focal bone pain or recent trauma requires radiography of the affected joint to rule out metabolic bone disease, tumor, or fracture. If there is a joint effusion in the absence of trauma or recent surgery, and signs of infection (e.g., fever, erythema, warmth) are present, subsequent arthrocentesis should be performed. Inflammatory synovial fluid containing monosodium urate crystals indicates a high probability of gout. Noninflammatory synovial fluid suggests osteoarthritis or internal derangement. Pitfalls in the diagnosis and early treatment of acute monoarthritis include failure to perform arthrocentesis, administering antibiotics before aspirating the joint when septic arthritis is suspected (or failing to start antibiotics after aspiration), and starting treatment based solely on laboratory data, such as an elevated uric acid level.

    A 62-year-old man was hospitalized for acute rheumatic fever. He had previously suffered from rheumatic fever at 15 years of age. The rheumatic fever was complicated by carditis, which caused valve disease that required surgical treatment. The incidence of rheumatic fever has decreased in most developed countries with improvements in sanitary conditions. The low incidence of this disease makes a timely and accurate diagnosis difficult. Due to the fact that both the first occurrence and recurrence of acute rheumatic fever can occur in the elderly and adults, this potential disease should not be overlooked when making a differential diagnosis.

    Background Use of topical NSAIDs to treat acute musculoskeletal conditions is widely accepted in some parts of the world, but not in others. Their main attraction is their potential to provide pain relief without associated systemic adverse events. Objectives To review the evidence from randomised, double-blind, controlled trials on the efficacy and safety of topically applied NSAIDs in acute pain. Search methods We searched MEDLINE, EMBASE, The Cochrane Library, and our own in-house database to December 2009. We sought unpublished studies by asking personal contacts and searching on-line clinical trial registers and manufacturers web sites. Selection criteria We included randomised, double-blind, active or placebo (inert carrier)-controlled trials in which treatments were administered to adult patients with acute pain resulting from strains, sprains or sports or overuse-type injuries (twisted ankle, for instance). There had to be at least 10 participants in each treatment arm, with application of treatment at least once daily. Data collection and analysis Two review authors independently assessed trial quality and validity, and extracted data. Numbers of participants achieving each outcome were used to calculate relative risk and numbers needed to treat (NNT) or harm (NNH) compared to placebo or other active treatment. Main results Forty-seven studies were included; most compared topical NSAIDs in the form of a gel, spray, or cream with a similar placebo, with 3455 participants in the overall analysis of efficacy. For all topical NSAIDs combined, compared with placebo, the number needed to treat to benefit (NNT) for clinical success, equivalent to 50% pain relief, was 4.5 (3.9 to 5.3) for treatment periods of 6 to 14 days. Topical diclofenac, ibuprofen, ketoprofen, and piroxicam were of similar efficacy, but indomethacin and benzydamine were not significantly better than placebo. Local skin reactions were generally mild and transient, and did not differ from

    Consecutive adult patients admitted to St. Bartholomew's Hospital with acute myelogenous leukaemia have been treated with a remission induction drug schedule consisting of daunorubicin and cytosine arabinoside. Intermittent five-day courses were used in 72 patients, and a complete remission was obtained in 39 patients (54%). An alternative drug schedule in 22 patients resulted in fewer remissions but this may have been due to age differences in the two groups. Age and initial platelet count were found to be important factors in determining the success of remission induction therapy; the older patients and those with low platelet counts responded less well. A series of 23 patients who achieved remissions was divided into two groups; one received intermittent combination chemotherapy as the only form of maintenance, and the other was given weekly immunotherapy in addition to the chemotherapy. The immunotherapy consisted of irradiated allogeneic leukaemic cells and B.C.G. Eight of the 10 patients on chemotherapy alone have already relapsed compared with five out of 13 patients in the immunotherapy group. It is hoped that these promising initial results with this form of maintenance will be confirmed as more patients enter the maintenance trials. PMID:4513355

    An 8-year-old girl presented with bilateral breast masses and was subsequently diagnosed with juvenile myelomonocytic leukemia. Juvenile myelomonocytic leukemia is a rare myelodysplastic syndrome that typically presents in boys younger than 3 years of age with splenomegaly, lymphadenopathy and skin findings. Bilateral breast masses in a child are rare and, as such, present a diagnostic dilemma due to the relative paucity of cases in the literature. We present a case of granulocytic sarcoma of the breasts in a patient with juvenile myelomonocytic leukemia. The authors hope that increased reporting and research regarding pediatric breast masses will help create awareness for such cases.

    The levels of intracisternal A-particle (IAP) mRNA were analyzed in a variety of myelomonocytic leukemia cell lines, peritoneally derived macrophages, and normal hemopoietic progenitors induced to differentiate. In both normal and leukemic cells, the highest level of IAP message was found in cells at an intermediate stage of myelomonocytic differentiation, namely, the promyelomonocyte. These results indicate that IAP sequence transcription is regulated differentially during myelomonocytic cell development and that in general, the expression pattern is preserved in leukemic cell lines in vitro. In addition, Northern (RNA) analysis detected only type I IAP transcripts as the major IAP message and the expressed IAP subtypes varied in certain cell lines. This is the first comprehensive study of IAP expression in the myelomonocytic lineage and provides a useful system to study the biology of IAPs. Images PMID:1848323

The analysis of the maintaining therapy in 22 patients affected with an acute myelocytic leukemia and living for more than 6 months revealed that the interval therapy with a high dosage of cytostatic combinations in the sense of the COAP scheme is preferable compared with the daily administration of 6-mercaptopurin, in addition methotrexate twice a week. Reasons for this are discussed.

    A growing number of reports state that regular exercise enhances brain function in older adults. Recently a functional near-infrared spectroscopy (fNIRS) study revealed that an acute bout of moderate exercise enhanced activation of the left dorsolateral prefrontal cortex (L-DLPFC) associated with Stroop interference in young adults. Whether this acute effect is also applicable to older adults was examined. Sixteen older adults performed a color-word matching Stroop task before and after 10 minutes of exercise on a cycle ergometer at a moderate intensity. Cortical hemodynamics of the prefrontal area was monitored with a fNIRS during the Stroop task. We analyzed Stroop interference (incongruent-neutral) as Stroop performance. Though activation for Stroop interference was found in the bilateral prefrontal area before the acute bout of exercise, activation of the right frontopolar area (R-FPA) was enhanced after exercise. In the majority of participants, this coincided with improved performance reflected in Stroop interference results. Thus, an acute bout of moderate exercise improved Stroop performance in older adults, and this was associated with contralateral compensatory activation.

    Acute mesenteric ischemia is commonly seen in old patients. This study was undertaken to show that mesenteric ischemia might be seen in individuals under 40 years of age and that its diagnosis is challenging. Twenty-six patients with acute mesenteric ischemia under the age of 40 were studied. The main symptom on admission was abdominal pain. Symptom duration varied between 12 h and 5 days. The medical history of the patients revealed that 9 had no previous diseases. Other 17 had predisposing factors in the first evaluation. None of the patients had any history of narcotic or drug abuse. Ten patients presented with signs and symptoms of sepsis and septic shock. Preoperative diagnosis was acute intestinal ischemia only in 6 patients. Preoperatively, all the patients had intestinal or colonic ischemia and necrosis; one had additional ischemia of the liver, stomach, duodenum, and pancreas. Six patients had massive intestinal necrosis. The overall postoperative complication and overall mortality rates were 61.5 and 26.9 %, respectively. Complications and mortality were determined to be associated with previous pulmonary disease, acidosis, presence of septic shock, acute renal failure, extent of the ischemia and extent of resection, second look operations, previous cardiac events, and the kind of affected bowel (colon involvement).

    Acute symptomatic seizures are seizures occurring in close temporal relationship with an acute central nervous system (CNS) insult. The objective of the study was to determine the frequency of presentation and etiological risk factors of acute symptomatic seizures among adult medical admissions. It was a two-year retrospective study of the medical files of adults patients admitted with acute symptomatic seizures as the first presenting event. There were 94 cases of acute symptomatic seizures accounting for 5.2% (95% CI: 4.17–6.23) of the 1,802 medical admissions during the period under review. There were 49 (52.1%) males and 45 (47.9%) females aged between 18 years and 84 years. The etiological risk factors of acute symptomatic seizures were infections in 36.2% (n = 34) of cases, stroke in 29.8% (n = 28), metabolic in 12.8% (n = 12), toxic in 10.6% (n = 10), and other causes in 10.6% (n = 10). Infective causes were more among those below fifty years while stroke was more in those aged fifty years and above. CNS infections and stroke were the prominent causes of acute symptomatic seizures. This is an evidence of the “double tragedy” facing developing countries, the unresolved threat of infectious diseases on one hand and the increasing impact of noncommunicable diseases on the other one.

    Increasing evidence suggests that regular moderate exercise increases neurogenesis in the dentate gyrus (DG) of the hippocampus and improves memory functions in both humans and animals. The DG is known to play a role in pattern separation, which is the ability to discriminate among similar experiences, a fundamental component of episodic memory. While long-term voluntary exercise improves pattern separation, there is little evidence of alterations in DG function after an acute exercise session. Our previous studies showing acute moderate exercise-enhanced DG activation in rats, and acute moderate exercise-enhanced prefrontal activation and executive function in humans, led us to postulate that acute moderate exercise may also activate the hippocampus, including more specifically the DG, thus improving pattern separation. We thus investigated the effects of a 10-min moderate exercise (50% V̇O2peak ) session, the recommended intensity for health promotion, on mnemonic discrimination (a behavioral index of pattern separation) in young adults. An acute bout of moderate exercise improved mnemonic discrimination performance in high similarity lures. These results support our hypothesis that acute moderate exercise improves DG-mediated pattern separation in humans, proposing a useful human acute-exercise model for analyzing the neuronal substrate underlying acute and regular exercise-enhanced episodic memory based on the hippocampus. © 2016 Wiley Periodicals, Inc.

    Here, we report a case of a 51-year-old man with acute pericardial tamponade requiring emergency pericardiocentesis after he suffered from sore throat, headache, malaise, and sweats for two weeks. Serological analyses revealed increased mumps IgM and IgG indicating an acute mumps infection whereas other bacterial and viral infections were excluded. In addition, MRI revealed atypical swelling of the left submandibular gland. Whereas mumps has become a rare entity in children due to comprehensive vaccination regimens in western civilizations, our case highlights mumps as an important differential diagnosis also in adults, where the virus can induce life-threatening complications such as pericardial tamponade.

    Eighty-five consecutive patients with acute lymphoblastic leukaemia (ALL), having a median age of 24 years (range 10-69 years), underwent induction and consolidation chemotherapy with weekly parenteral vincristine, Adriamycin, l-asparaginase and daily oral prednisone (VAAP), followed by standard (CNS) prophylaxis. Maintenance therapy was given for 3 years and consisted of daily 6-mercaptopurine, weekly methotrexate and monthly intrathecal therapy, with drug intensification comprising either vincristine, Adriamycin and l-asparaginase (VAA) or cyclophosphamide, vincristine, cytosine arabinoside and prednisone (COAP). Complete remission (CR) was obtained in 59 patients (69%) and only the French-American-British (FAB) L1 morphology was a significant predictive factor (P = 0.048). Twenty-three patients failed to achieve CR and of these 12 had primary drug resistance. Median follow-up is currently 260 weeks, median predicted survival of all patients is 58 weeks and for those who achieved CR it is 104 weeks. Median duration of CR is 70 weeks. Of the prognostic factors for survival, only FAB L1 subtype was significant. Bone marrow relapses occurred in 29 patients, and of these 9 (31%) achieved CR. There has been CNS relapse in two patients and both have died. Eleven patients continue in CR off therapy, with a median of 152 weeks. This regimen is effective, with acceptable toxicity, and a number of patients are potentially cured. The incidence of resistant and relapsing disease is an argument for further intensifying both induction and postinduction therapy.

    In order to register data on costs for episodes of acute hepatitis B virus (HBV) infection in adults, the medical records from 70 adults with acute HBV infection seen at Roslagstull's Hospital in Stockholm, Sweden, were reviewed. All cost-consuming events due to medical treatment, absence from work, and secondary prophylaxis were registered. The average cost was 1,230 pounds for medical treatment, 570 pounds for work loss and 290 pounds for secondary cases and prophylaxis, a total of 2,090 pounds in 1992 prices. This figure is considerably lower than that reported in 3 previous European studies. Accurate estimates of the costs for a case of HBV, as well as those of different vaccination strategies, are essential when economic aspects of HBV vaccination programmes are discussed.

  13. A Bayesian approach to acute infectious diarrhea in adults.

    Goodgame, Richard

    2006-06-01

    Acute infectious diarrhea is a yearly occurrence for most Americans, and is associated with 1 million hospitalizations and about 6000 deaths in the United States annually. Up to 80% of acute infectious diarrhea is caused by noroviruses, which produce a clinically mild illness with a predictable short course and good outcome that make laboratory testing and antimicrobial treatment unnecessary. Most diarrhea-causing bacteria and protozoa can cause a clinical illness "like norovirus"; when they do so in healthy adults neither specialized testing nor antimicrobials is required. The presence or absence of epidemiologic evidence (such as travel, hospitalization, antibiotic use, other exposures)and clinical evidence (such as diarrhea frequency and duration, severity of abdominal pain and fever, character of stool, presence of chronic illness or immune deficiency) can change the probability of "not norovirus" from as low as 8% to as high as 100%. Such probabilities guide the use of laboratory testing and antimicrobial therapy in patients who have acute infectious diarrhea.

    Acute myeloid leukemia and acute lymphoblastic leukemia remain devastating diseases. Only approximately 40% of younger and 10% of older adults are long-term survivors. Although curing the leukemia is always the most formidable challenge, complications from the disease itself and its treatment are associated with significant morbidity and mortality. Such complications, discussed herein, include tumor lysis, hyperleukocytosis, cytarabine-induced cellebellar toxicity, acute promyelocytic leukemia differentiation syndrome, thrombohemorrhagic syndrome in acute promyelocytic leukemia, L-asparaginase-associated thrombosis, leukemic meningitis, neutropenic fever, neutropenic enterocolitis, and transfussion-associated GVHD. Whereas clinical trials form the backbone for the management of acute leukemia, emergent clinical situations, predictable or not, are common and do not readily lend themselves to clinical trial evaluation. Furthermore, practice guidelines are often lacking. Not only are prospective trials impractical because of the emergent nature of the issue at hand, but clinicians are often reluctant to randomize such patients. Extensive practical experience is crucial and, even if there is no consensus, management of such emergencies should be guided by an understanding of the underlying pathophysiologic mechanisms.

  15. Effect of acute ethanol and acute allopregnanolone on spatial memory in adolescent and adult rats.

    The effects of ethanol differ in adolescent and adult rats on a number of measures. The evidence of the effects of ethanol on spatial memory in adolescents and adults is equivocal. Whether adolescents are more or less sensitive to ethanol-induced impairment of spatial memory acquisition remains unclear; with regard to the effects of acute ethanol on spatial memory retrieval there is almost no research looking into any age difference. Thus, we examined the effects of acute ethanol on spatial memory in the Morris Watermaze in adolescents and adults. Allopregnanolone (ALLO) is a modulator of the GABA(A) receptor and has similar behavioral effects as ethanol. We sought to also determine the effects of allopreganolone on spatial memory in adolescent and adults. Male adolescent (post natal [PN]28-30) and adult (PN70-72) rats were trained in the Morris Watermaze for 6 days and acute doses of ethanol (saline, 1.5 and 2.0 g/kg) or ALLO (vehicle, 9 and 18 mg/kg) were administered on Day 7. A probe trial followed on Day 8. As expected, there were dose effects; higher doses of both ethanol and ALLO impaired spatial memory. However, in both the ethanol and ALLO conditions adolescents and adults had similar spatial memory impairments. The current results suggest that ethanol and ALLO both impair hippocampal-dependent spatial memory regardless of age in that once learning has occurred, ethanol or ALLO does not differentially impair the retrieval of spatial memory in adolescents and adults. Given the mixed results on the effect of ethanol on cognition in adolescent rats, additional research is needed to ascertain the factors critical for the reported differential results.

    Treatment of older adults with acute myeloid leukemia (AML) or myelodysplastic syndromes (MDS) is challenging because of disease morbidity and associated treatments. Both diseases represent a genetically heterogeneous group of disorders primarily affecting older adults, with treatment strategies ranging from supportive care to hematopoietic stem-cell transplantation. Although selected older adults can benefit from intensive therapies, as a group they experience increased treatment-related morbidity, are more likely to relapse, and have decreased survival. Age-related outcome disparities are attributed to both tumor and patient characteristics, requiring an individualized approach to treatment decision making beyond consideration of chronologic age alone. Selection of therapy for any individual requires consideration of both disease-specific risk factors and estimates of treatment tolerance and life expectancy derived from evaluation of functional status and comorbidity. Although treatment options for older adults are expanding, clinical trials accounting for the heterogeneity of tumor biology and aging are needed to define standard-of-care treatments for both disease groups. In addition, trials should include outcomes addressing quality of life, maintenance of independence, and use of health care services to assist in patient-centered decision making. This review will highlight available evidence in treatment of older adults with AML or MDS and unanswered clinical questions for older adults with these diseases.

    During the last decade, increasing attention has been paid to a unique group of patients with acute lymphoblastic leukemia (ALL) who lie at the crossroad of therapeutic care by pediatric and adult hematologists/oncologists. ALL is a disease that affects infants, children, adolescents, and adult patients. With current therapies, the vast majority of children with ALL are now long-term survivors; unfortunately, the same good results have not yet been obtained for adults with ALL. This review will describe current controversies surrounding the treatment of adolescents and young adults with ALL--a group who finds themselves in the transition from "pediatric" to "adult" treatment approaches. The review focuses on recent insights into disease biology, prognostic factors, and treatment outcomes that have led to a series of prospective clinical trials specifically designed for adolescents and younger adults (AYAs) with ALL. These trials have been designed to provide important new clinical, psychosocial, and biological insights, and to further improve the survival of this challenging and unique group of patients.

    Bacterial endotoxin (lipopolysaccharide, LPS), at high concentration is responsible for sepsis, and neonatal mortality, however low concentration of LPS protected the pancreas against acute damage. The aim of this study was to investigate the effect of exposition of suckling rats to LPS on the course of acute pancreatitis at adult age. Suckling rat (30-40g) received intraperitoneal (i.p.) injection of saline (control) or LPS from Escherichia coli or Salmonella typhi (5, 10 or 15 mg/kg-day) during 5 consecutive days. Two months later these rats have been subjected to i.p. cearulein infusion (25 microg/kg) to produce caerulein-induced pancreatitis (CIP). The following parameters were tested: pancreatic weight and morphology, plasma amylase and lipase activities, interleukin 1beta (IL-1 beta), interleukin 6 (IL-6), and interleukin 10 (IL-10) plasma concentrations. Pancreatic concentration of superoxide dismutase (SOD) and lipid peroxidation products; malondialdehyde (MDA) and 4-hydroxynonenal (4-HNE) have been also measured. Caerulein infusion produced CIP in all animals tested, that was confirmed by histological examination. In the rats, which have been subjected in the neonatal period of life to LPS at doses 10 or 15 mg/kg-day x 5 days, all manifestations of CIP have been reduced. In these animals acute inflammatory infiltration of pancreatic tissue and pancreatic cell vacuolization have been significantly diminished. Also pancreatic weight, plasma lipase and alpha-amylase activities, as well as plasma concentrations of IL-1beta and IL-6 have been markedly decreased, whereas plasma anti-inflammatory IL-10 concentration was significantly increased in these animals as compared to the control rats, subjected in the infancy to saline injection instead of LPS. Caerulein-induced fall in pancreatic SOD concentration was reversed and accompanied by significant reduction of MDA + 4 HNE in the pancreatic tissue. The effects of LPS derived from E. coli or S. typhi were similar

    Introduction Intestinal malrotation refers to the partial or complete failure of rotation of midgut around the superior mesenteric vessels in embryonic life. Arrested midgut rotation results due to narrow-based mesentery and increases the risk of twisting midgut and subsequent obstruction and necrosis. Presentation of case 40 years old female patient admitted to emergency service with acute abdomen and computerized tomography scan showed dilated large and small intestine segments with air-fluid levels and twisted mesentery around superior mesenteric artery and vein indicating “whirpool sign”. Discussion Malrotation in adults is a rare cause of midgut volvulus as though it should be considered in differential diagnosis in patients presented with acute abdomen and intestinal ischemia. Even though clinical symptoms are obscure, adult patients usually present with vomiting and recurrent abdominal pain due to chronic partial obstruction. Contrast enhanced radiograph has been shown to be the most accurate method. Typical radiological signs are corkscrew sign, which is caused by the dilatation of various duodenal segments at different levels and the relocation of duodenojejunal junction due to jejunum folding. As malrotation commonly causes intestinal obstruction, patients deserve an elective laparotomy. Conclusion Malrotation should be considered in differential diagnosis in patients presented with acute abdomen and intestinal ischemia. Surgical intervention should be prompt to limit morbidity and mortality. PMID:27015011

    We report a case of chronic myelomonocytic leukaemia (CMMoL) in a 68-year-old man who developed osteomyelitis of the mandible. At the initial visit, he reported uncontrolled gingival bleeding, despite self-administered haemostasis. He complained of severe pain in the socket, despite potent opioid analgesia. After consultation with the internal medicine specialists, we undertook a surgical anti-inflammatory approach that included sequestrectomy with massive blood transfusion. His physical condition was ameliorated after the surgical procedure, and he was discharged from the hospital. However, 3 months later, he died because of cardiac arrest after haemorrhagic shock and cardiovascular failure because his CMMoL had developed to an acute blastic crisis. This experience demonstrates that the most important goal in such cases is to alleviate a patient's discomfort by applying minimally invasive actions to eliminate infection and improve the quality of life without causing deterioration in the CMMoL status.

    Objectives Poor sleep diminishes mental and physical health. The objective of this study was to examine associations between sleep disturbance and interleukin-6 (IL-6) responses to acute mental stress in older adults. Design Observational study of community-dwelling, healthy older adults. Setting Participants completed the study in a clinical research laboratory of a mid-sized university. Participants Generally healthy, community-dwelling men and women 50 years of age and older. Measurements IL-6 and negative affect at rest and following a series of challenging cognitive tests; sleep quality; depressive symptoms; perceived stress; loneliness. Results Participants categorized as poor sleepers based on Pittsburgh Sleep Quality Index scores had significantly larger IL-6 responses to the cognitive stressors compared to good sleepers. The association between poor sleep and heightened IL-6 response to acute stress was not explained by other psychosocial factors previously linked to immune dysregulation, including depressive symptoms, perceived stress, and loneliness. Conclusions Findings add to the growing evidence for poor sleep as an independent risk factor for poor mental and physical health. Older adults may be particularly vulnerable to effects of sleep disturbance due to significant age-related changes in both sleep and inflammatory regulation. PMID:22327621

    The outcome of adults and children with Acute Promyelocytic Leukemia (APL) has dramatically changed since the introduction of all trans retinoic acid (ATRA) therapy. Based on the results of several multicenter trials, the current recommendations for the treatment of patients with APL include ATRA and anthracycline-based chemotherapy for the remission induction and consolidation, and ATRA combined with low-dose chemotherapy for maintenance. This has improved the prognosis of APL by increasing the complete remission (CR) rate, actually > 90%, decreasing the induction deaths and by reducing the relapse rate, leading to cure rates nowadays exceeding 80% considering both adults and children.1-9 More recently the combination of ATRA and arsenic trioxide (ATO) as induction and consolidation therapy has been shown to be at least not inferior and possibly superior to ATRA plus chemotherapy in adult patients with APL conventionally defined as non-high risk (Sanz score).10 Childhood APL has customarily been treated on adult protocols. Data from several trials have shown that the overall outcome in pediatric APL appears similar to that reported for the adult population; however, some clinical and therapeutic aspects differ in the two cohorts which require some important considerations and treatment adjustments.

    Out of 64 consecutive unselected patients with acute myeloid leukaemia studied during 1973-6, five developed clinical evidence of spread to the central nervous system (CNS). Neuroradiological examination showed cerebral deposits in three, in whom rapid symptomatic relief was obtained with radiotherapy. In two of these patients who developed solid intracranial deposits haematological remission could be reinduced or maintained; they were still alive 86 and 134 weeks later. When patients presented with spread to the CNS complicating generalised uncontrolled leukaemia they had short survivals. CNS infiltration may respond dramatically to appropriate treatment provided that it is not associated with generalised uncontrolled leukaemia, which has a poor prognosis. In view of this, routine "prophylaxis" of the CNS in adult acute myeloid leukaemia does not seem justified at present. Images FIG 1 FIG 2 FIG 3 PMID:283873

    The primary objective of this review was to update and discuss the current concepts and the results of the treatment of acute lymphoblastic leukemia (ALL) in adolescents and young adults (AYA). After a brief consideration of the epidemiologic and clinicobiologic characteristics of ALL in the AYA population, the main retrospective comparative studies stating the superiority of pediatric over adult-based protocols were reviewed. The most important prospective studies in young adults using pediatric inspired or pediatric unmodified protocols were also reviewed emphasizing their feasibility at least up to the age of 40 yr and their promising results, with event-free survival rates of 60–65% or greater. Results of trials from pediatric groups have shown that the unfavourable prognosis of adolescents is no more adequate. The majority of the older adolescents with ALL can be cured with risk-adjusted and minimal residual disease-guided intensive chemotherapy, without stem cell transplantation. However, some specific subgroups, which are more frequent in adolescents than in children (e.g., early pre-T, iAMP21, and BCR-ABL-like), deserve particular attention. In summary, the advances in treatment of ALL in adolescents have been translated to young adults, and that explains the significant improvement in survival of these patients in recent years.

    Abstract Various viral kinetics among patients with acute hepatitis B (AHB) have been observed in clinical practice. This study investigated the virological, biochemical, and serological characteristics of AHB in adults. A total of 192 adult patients with AHB were recruited between December 2010 and January 2014. The quantification of biochemical and serologic markers for hepatitis B virus (HBV) infection was monitored from the onset. Of the 192 patients, 113 patients were followed up. One patient died due to acute liver failure, 2 developed chronic HBV infection. Clinical recovery was observed in 110 patients; 92.7% (102/110) achieved clinical recovery within 24 weeks, and 7.3% (8/110) between 24 and 44 weeks. There were 3 different viral kinetics patterns among the patients with AHB: the clearance of HBV DNA preceded hepatitis B e antigen (HBeAg) and hepatitis B surface antigen (HBsAg), the clearance of HBeAg preceded HBV DNA and HBsAg, the clearance of HBsAg preceded HBV DNA and HBeAg. In the absence of HBV DNA clearance within 13 weeks, the risk of development of chronic HBV infection increased. The serologic HBV markers clearance occurred between 24 and 44 weeks (6–11 months) from the onset in 8 of the AHB patients, which was longer than 6 months. Thus, AHB may be redefined as HBV DNA undetectable, HBsAg and HBeAg seroconversion within 44 weeks. PMID:28207518

    Abstract Background: Hemophagocytic lymphohistiocytosis (HLH) is a rare condition that can be caused by a primary or acquired disorder of uncontrolled immune response. Liver injury is a common complication of HLH; however, HLH presenting as acute liver failure (ALF) has rarely been reported in adults. Case summary: A 34-year-old man was admitted to our hospital with nausea and fatigue persisting for 2 weeks and jaundice for 1 week. He had hyperthermia at the onset of disease. At admission, he had severe liver injury with unknown etiology. The laboratory data showed that he had hyperferritinemia, thrombocytopenia, anemia, hypertriglyceridemia, and hypofibrinogenemia. Finally, a bone marrow biopsy revealed hemophagocytic cells, and he was diagnosed with HLH. The patient was treated with prednisone and plasma exchange. However, the liver function of the patient deteriorated, and he finally died of multiorgan failure. Conclusions: Reports of adult patients with ALF caused by HLH have increased, and HLH should be suspected in patients with ALF of indeterminate cause. Although the efficacy of the treatment strategy recommended by the HLH 2004 remains to be confirmed in adult patients with ALF caused by HLH, early diagnosis and prompt combined treatment with steroids and cyclosporin A or etoposide should be emphasized.

    The net benefits of induction therapy for older adults with acute myeloid leukemia (AML) remain controversial. Because AML in older adults is a heterogeneous disease, it is important to identify those who are unlikely to benefit from induction therapy based on information available at the initial assessment. We used next-generation sequencing to analyze TP53 mutation status in AML patients aged 60 years or older, and evaluated its effects on outcomes. TP53 mutations were detected in 12 of 77 patients (16 %), and there was a significant association between TP53 mutations and monosomal karyotype. Patients with TP53 mutations had significantly worse survival than those without (P = 0.009), and multivariate analysis identified TP53 mutation status as the most significant prognostic factor for survival. Neverthelsess, TP53-mutated patients had a 42 % chance of complete remission and a median survival of 8.0 months, which compares favorably with those who did not undergo induction therapy, even in the short term. These results suggest that screening for TP53 mutations at diagnosis is useful for identifying older adults with AML who are least likely to respond to chemotherapy, although the presence of this mutation alone does not seem to justify rejecting induction therapy.

    Background Tenoxicam is a non-steroidal anti-inflammatory drug (NSAID) licensed for use in rheumatic disease and other musculoskeletal disorders in the UK, and is widely available in other countries worldwide. This review sought to evaluate the efficacy and safety of oral tenoxicam in acute postoperative pain, using clinical studies of patients with established pain, and with outcomes measured primarily over 6 hours using standard methods. This type of study has been used for many decades to establish that drugs have analgesic properties. Objectives To assess the efficacy of single dose oral tenoxicam in acute postoperative pain, and any associated adverse events. Search methods We searched The Cochrane Library (Issue 1, 2009), MEDLINE (March 2009); EMBASE via Ovid (March 2009); the Oxford Pain Relief Database. Selection criteria Randomised, double-blind, placebo-controlled clinical trials of oral tenoxicam for relief of acute postoperative pain in adults. Data collection and analysis Two review authors independently assessed trial quality and extracted data. The area under the “pain relief versus time” curve was used to derive the proportion of participants with tenoxicam experiencing least 50% pain relief over 4 to 6 hours, using validated equations. The number needed to treat to benefit (NNT) was calculated using 95% confidence intervals (CI). The proportion of participants using rescue analgesia over a specified time period, and time to use of rescue analgesia, were sought as additional measures of efficacy. Information on adverse events and withdrawals was also collected. Main results Not one of sixteen studies identified by the searches and examined in detail studied oral tenoxicam in patients with established postoperative pain and therefore no results are available. Authors’ conclusions In the absence of evidence of efficacy for oral tenoxicam in acute postoperative pain, its use in this indication is not justified at present. Because trials clearly

    More than half of the patients with acute myeloid leukaemia (AML) are older than 60years. The treatment outcomes in this group remain poor with a median overall survival of <1year. Selecting initial treatment for these patients involves an assessment of 'fitness' for induction chemotherapy. This is done based on patient and disease-related characteristics which help to estimate treatment-related mortality and chance of complete remission with induction chemotherapy. If the risk of treatment-related mortality is high and/or the likelihood of a patient achieving a complete remission is low, lower-intensity treatment (low-dose cytarabine, decitabine and azacitidine) should be discussed. As outcomes in both groups of patients remain poor, enrolment into clinical trials of novel agents with varying mechanisms of action should be considered for all older adults with AML. Novel agents in Phase III development include CPX-351, guadecitabine (SGI-110), quizartinib, crenolanib, sapacitabine, vosaroxin and volasertib.

    Acute pharyngitis in adults is one of the most common infectious diseases seen in general practitioners' consultations. Viral aetiology is the most common. Among bacterial causes, the main agent is Streptococcus pyogenes or group A β-haemolytic streptococcus (GABHS), which causes 5%-30% of the episodes. In the diagnostic process, clinical assessment scales can help clinicians to better predict suspected bacterial aetiology by selecting patients who should undergo a rapid antigen detection test. If these techniques are not performed, an overdiagnosis of streptococcal pharyngitis often occurs, resulting in unnecessary prescriptions of antibiotics, most of which are broad spectrum. Consequently, management algorithms that include the use of predictive clinical rules and rapid tests have been set up. The aim of the treatment is speeding up symptom resolution, reducing the contagious time span and preventing local suppurative and non-suppurative complications. Penicillin and amoxicillin are the antibiotics of choice for the treatment of pharyngitis. The association of amoxicillin and clavulanate is not indicated as the initial treatment of acute infection. Neither are macrolides indicated as first-line therapy; they should be reserved for patients allergic to penicillin. The appropriate diagnosis of bacterial pharyngitis and proper use of antibiotics based on the scientific evidence available are crucial. Using management algorithms can be helpful in identifying and screening the cases that do not require antibiotic therapy.

    Stromal infiltration of myelomonocytic cells is a hallmark of pancreatic ductal adenocarcinoma (PDAC) and is related to a poor prognosis. However, the detailed mechanism for the recruitment of myelomonocytic cells to pancreatic cancer tissue remains unclear. In the present study, pancreatic cancer cells secreted high levels of adrenomedullin (ADM), and CD11b+ myelomonocytic cells expressed all components of ADM receptors, including GPR182, CRLR, RAMP2 and RAMP3. ADM enhanced the migration and invasion of myelomonocytic cells through activation of the MAPK, PI3K/Akt and eNOS signaling pathways, as well as the expression and activity of MMP-2. ADM also promoted the adhesion and trans-endothelial migration of myelomonocytic cells by increasing expression of VCAM-1 and ICAM-1 in endothelial cells. In addition, ADM induced macrophages and myeloid-derived suppressor cells (MDSCs) to express pro-tumor phenotypes. ADM knockdown in tumor-bearing mice or administration of AMA, an ADM antagonist, significantly inhibited the recruitment of myelomonocytic cells and tumor angiogenesis. Moreover, in vivo depletion of myelomonocytic cells using clodronate liposomes suppressed the progression of PDAC. These results reveal a novel function of ADM in PDAC, and suggest ADM is a promising target in the treatment of PDAC. PMID:27391260

  1. Single dose oral ibuprofen for acute postoperative pain in adults

    2014-01-01

    Background This review updates a 1999 Cochrane review showing that ibuprofen at various doses was effective in postoperative pain in single dose studies designed to demonstrate analgesic efficacy. New studies have since been published. Ibuprofen is one of the most widely used non-steroidal anti-inflammatory (NSAID) analgesics both by prescription and as an over-the-counter medicine. Ibuprofen is used for acute and chronic painful conditions. Objectives To assess analgesic efficacy of ibuprofen in single oral doses for moderate and severe postoperative pain in adults. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to May 2009. Selection criteria Randomised, double blind, placebo-controlled trials of single dose orally administered ibuprofen (any formulation) in adults with moderate to severe acute postoperative pain. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Pain relief or pain intensity data were extracted and converted into the dichotomous outcome of number of participants with at least 50% pain relief over 4 to 6 hours, from which relative risk and number-needed-to-treat-to-benefit (NNT) were calculated. Numbers of participants using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Information on adverse events and withdrawals were collected. Main results Seventy-two studies compared ibuprofen and placebo (9186 participants). Studies were predominantly of high reporting quality, and the bulk of the information concerned ibuprofen 200 mg and 400 mg. For at least 50% pain relief compared with placebo the NNT for ibuprofen 200 mg (2690 participants) was 2.7 (2.5 to 3.0) and for ibuprofen 400 mg (6475 participants) it was 2.5 (2.4 to 2.6). The proportion with at least 50% pain relief was 46% with 200 mg and 54% with 400 mg. Remedication within 6 hours was less

    A statistical analysis of the prognostic significance of eight pretreatment variables was undertaken for 71 previously untreated adult patients with acute leukemia seen at M.D. Anderson Hospital over a 5 1/2-year period. None of the patients had received any prior therapy. Nearly all of the patients (68 of the 71) were treated with 4- or 5-day courses of arabinosyl-cytosine alone or in combination with cyclophosphamide, vincristine (oncovin) and prednisone (COAP). The pretreatment variables studied were age at diagnosis, the percent labeling index of the bone marrow leukemic cells, diagnosis, the highest temperature prior to start of treatment, the marrow clot section cellularity and smear differential percent of blasts, percent absolute marrow leukemic cell infiltrate and absolute number of blasts X 10(3)/mm3 in the peripheral blood. Fifty-one patients had acute myeloblastic leukemia (AML) and 20 patients had acute lymphoblastic leukemia (ALL). Using a statistical regression model approach, the only variables found to be of significant prognostic importance with respect to the probability of complete remission for AML patients were the pretreatment percent labeling index, the age of the patient and the highest temperature prior to start of treatment. Unlike AML, the initial percent labeling index did not appear to be of prognostic significance for ALL patients. AML patients with high labeling indices (larger than or equal to 9%) and young patients in general (especially those less than 40 years old) had the best remission rates. With respect to the length of complete remission and survival for all patients, the only important variables were the pretreatment percent labeling index and the age of the patient, respectively. Once in complete remission, an initially high labeling index was an unfavorable sign with respect to length of remission, regardless of the patient's diagnosis. The results of this study are supportive of studies in experimental systems

    Acetaminophen (APAP) overdose induces acute liver injury. The aim of the present study was to analyze the difference of susceptibility between immature and adult mice to APAP-induced acute liver injury. Weanling immature and adult mice were injected with APAP (300 mg/kg). As expected, immature mice were more susceptible than adult mice to APAP-induced acute liver injury. APAP-evoked hepatic c-Jun N-terminal kinase phosphorylation was stronger in immature mice than in adult mice. Hepatic receptor-interacting protein (RIP)1 was obviously activated at APAP-exposed immature and adult mice. Interestingly, hepatic RIP3 activation was more obvious in APAP-treated immature mice than adult mice. Although there was no difference on hepatic GSH metabolic enzymes between immature and adult mice, immature mice were more susceptible than adult mice to APAP-induced hepatic GSH depletion. Of interest, immature mice expressed a much higher level of hepatic Cyp2e1 and Cyp3a11 mRNAs than adult mice. Correspondingly, immature mice expressed a higher level of hepatic CYP2E1, the key drug metabolic enzyme that metabolized APAP into the reactive metabolite NAPQI. These results suggest that a higher level of hepatic drug metabolic enzymes in immature mice than adult mice might contribute to the difference of susceptibility to APAP-induced acute liver injury.

    Hydroxyurea is the standard therapy of chronic myelomonocytic leukemia (CMML) presenting with advanced myeloproliferative and/or myelodysplastic features. Response to hypomethylating agents has been reported in heterogeneous series of CMML. We conducted a phase 2 trial of decitabine (DAC) in 39 patients with advanced CMML defined according to a previous trial. Median number of DAC cycles was 10 (range, 1-24). Overall response rate was 38% with 4 complete responses (10%), 8 marrow responses (21%), and 3 stable diseases with hematologic improvement (8%). Eighteen patients (46%) demonstrated stable disease without hematologic improvement, and 6 (15%) progressed to acute leukemia. With a median follow-up of 23 months, overall survival was 48% at 2 years. Mutations in ASXL1, TET2, AML1, NRAS, KRAS, CBL, FLT3, and janus kinase 2 (JAK2) genes, and hypermethylation of the promoter of the tumor suppressor gene TIF1γ, did not predict response or survival on DAC therapy. Lower CJUN and CMYB gene expression levels independently predicted improved overall survival. This trial confirmed DAC efficacy in approximately 40% of CMML patients with advanced myeloproliferative or myelodysplastic features and suggested that CJUN and CMYB expression could be potential biomarkers in this setting. This trial is registered at EudraCT (eudract.ema.europa.eu) as #2008-000470-21 and www.clinicaltrials.gov as #NCT01098084.

    Introduction Household air pollution from solid fuel burning kills over 4 million people every year including half a million children from acute lower respiratory infections. Although biologically plausible, it is not clear whether household air pollution is also associated with acute lower respiratory infections in adults. We systematically reviewed the literature on household air pollution and acute lower respiratory infection in adults to identify knowledge gaps and research opportunities. Methods Ten bibliographic databases were searched to identify studies of household air pollution and adult acute lower respiratory infection. Data were extracted from eligible studies using standardised forms. Results From 4617 titles, 513 abstracts and 72 full-text articles were reviewed. Eight studies met the inclusion criteria of which 2 found a significant adjusted increased risk of acute lower respiratory infection, 2 identified a univariate association whilst 4 found no significant association. Study quality was generally limited. Heterogeneity in methods and findings precluded meta-analysis. Discussion A systematic review of the literature found limited evidence for an association between household air pollution and risk of acute lower respiratory infection in adults. Additional research, with carefully defined exposure and outcome measures, is required to complete the risk profile caused by household air pollution in adults. Registration number CRD42015028042.

    Bacillus cereus, which used to be considered non-pathogenic, was isolated from the blood of a patient with acute leukemia who was receiving intensive chemotherapy. Fatal bacteremia developed with a clinical syndrome of acute gastroenteritis, followed by both meningoencephalitis with subarachnoid hemorrhage and multiple liver abscesses probably caused by infective vasculitis. Surveillance stool cultures revealed colonization with the organism prior to the onset of diarrhea, and repetitive blood cultures were found to be positive. Thus, this case suggested some new important clinicopathologic features of true B. cereus bacteremia complicating acute leukemia.

    Chronic myelomonocytic leukemia is similar to but a separate entity from both myeloproliferative neoplasms and myelodysplastic syndromes, and shows either myeloproliferative or myelodysplastic features. We ask whether this distinction may have a molecular basis. We established the gene expression profiles of 39 samples of chronic myelomonocytic leukemia (including 12 CD34-positive) and 32 CD34-positive samples of myelodysplastic syndromes by using Affymetrix microarrays, and studied the status of 18 genes by Sanger sequencing and array-comparative genomic hybridization in 53 samples. Analysis of 12 mRNAS from chronic myelomonocytic leukemia established a gene expression signature of 122 probe sets differentially expressed between proliferative and dysplastic cases of chronic myelomonocytic leukemia. As compared to proliferative cases, dysplastic cases over-expressed genes involved in red blood cell biology. When applied to 32 myelodysplastic syndromes, this gene expression signature was able to discriminate refractory anemias with ring sideroblasts from refractory anemias with excess of blasts. By comparing mRNAS from these two forms of myelodysplastic syndromes we derived a second gene expression signature. This signature separated the myelodysplastic and myeloproliferative forms of chronic myelomonocytic leukemias. These results were validated using two independent gene expression data sets. We found that myelodysplastic chronic myelomonocytic leukemias are characterized by mutations in transcription/epigenetic regulators (ASXL1, RUNX1, TET2) and splicing genes (SRSF2) and the absence of mutations in signaling genes. Myelodysplastic chronic myelomonocytic leukemias and refractory anemias with ring sideroblasts share a common expression program suggesting they are part of a continuum, which is not totally explained by their similar but not, however, identical mutation spectrum.

    Myelodysplastic syndromes and chronic myelomonocytic leukemia (CMML) are characterized by mutations in genes encoding epigenetic modifiers and aberrant DNA methylation. DNA methyltransferase inhibitors (DMTis) are used to treat these disorders, but response is highly variable, with few means to predict which patients will benefit. Here, we examined baseline differences in mutations, DNA methylation, and gene expression in 40 CMML patients who were responsive or resistant to decitabine (DAC) in order to develop a molecular means of predicting response at diagnosis. While somatic mutations did not differentiate responders from nonresponders, we identified 167 differentially methylated regions (DMRs) of DNA at baseline that distinguished responders from nonresponders using next-generation sequencing. These DMRs were primarily localized to nonpromoter regions and overlapped with distal regulatory enhancers. Using the methylation profiles, we developed an epigenetic classifier that accurately predicted DAC response at the time of diagnosis. Transcriptional analysis revealed differences in gene expression at diagnosis between responders and nonresponders. In responders, the upregulated genes included those that are associated with the cell cycle, potentially contributing to effective DAC incorporation. Treatment with CXCL4 and CXCL7, which were overexpressed in nonresponders, blocked DAC effects in isolated normal CD34+ and primary CMML cells, suggesting that their upregulation contributes to primary DAC resistance.

    Nucleophosmin (NPM1) mutations in chronic myelomonocytic leukemia (CMML) are extremely uncommon, and the clinicopathologic features of these neoplasms are poorly characterized. Over a 10-yr interval, NPM1 mutation analysis was performed in 152 CMML at our institution. NPM1 mutations were identified in 8 (5.3%) patients, five men and three women, with a median age of 72 yr (range, 27-87). In all patients, the bone marrow was hypercellular with multilineage dysplasia, monocytosis, and retained maturation supporting a diagnosis of CMML. NPM1 mutation allele burden was <5% in two patients and >10% in six patients. Four (50%) patients, all with >10% NPM1, progressed AML with a median interval of 11 months (range, 1-21). Compared with 144 CMML without NPM1 mutations, CMML patients with NPM1 mutation presented with more severe anemia (P = 0.053), higher BM monocyte percentage (P = 0.033), and an increased tendency for AML progression (P = 0.088) and an inferior overall survival (P = 0.076). Mutations involving NRAS/KRAS (2/7), TET2(2/5), ASXL1(1/5,) and FLT3(0/8) were not significantly different between these two groups. In summary, CMML with NPM1 mutation shows histopathological features of CMML, but patients appear to have a high probability for AML progression and may require aggressive clinical intervention, especially in patients with a high mutation burden.

    Extracorporeal life support (ECLS) is an artificial means of maintaining adequate oxygenation and carbon dioxide elimination to enable injured lungs to recover from underlying disease. Technological advances have made ECLS devices smaller, less invasive, and easier to use. ECLS might, therefore, represent an important step towards improved management and outcomes of patients with acute respiratory distress syndrome. Nevertheless, rigorous evidence of the ability of ECLS to improve short-term and long-term outcomes is needed before it can be widely implemented. Moreover, how to select patients and the timing and indications for ECLS in severe acute respiratory distress syndrome remain unclear. We describe the physiological principles, the putative risks and benefits, and the clinical evidence supporting the use of ECLS in patients with acute respiratory distress syndrome. Additionally, we discuss controversies and future directions, such as novel technologies and indications, mechanical ventilation of the native lung during ECLS, and ethics considerations.

    In this study, we aimed to investigate the pathways of recognition of acute lymphoblastic leukemia blasts by natural killer cells and to verify whether differences in natural killer cell activating receptor ligand expression among groups defined by age of patients, or presence of cytogenetic/molecular aberrations correlate with the susceptibility to recognition and killing. We analyzed 103 newly diagnosed acute lymphoblastic leukemia patients: 46 adults and 57 children. Pediatric blasts showed a significantly higher expression of Nec-2 (P=0.03), ULBP-1 (P=0.01) and ULBP-3 (P=0.04) compared to adult cells. The differential expression of these ligands between adults and children was confined to B-lineage acute lymphoblastic leukemia with no known molecular alterations. Within molecularly defined subgroups of patients, a high surface expression of NKG2D and DNAM1 ligands was found on BCR-ABL(+) blasts, regardless of patient age. Accordingly, BCR-ABL(+) blasts proved to be significantly more susceptible to natural killer-dependent lysis than B-lineage blasts without molecular aberrations (P=0.03). Cytotoxic tests performed in the presence of neutralizing antibodies indicated a pathway of acute lymphoblastic leukemia cell recognition in the setting of the Nec-2/DNAM-1 interaction. These data provide a biological explanation of the different roles played by alloreactive natural killer cells in pediatric versus adult acute lymphoblastic leukemia and suggest that new natural killer-based strategies targeting specific subgroups of patients, particularly those BCR-ABL(+), are worth pursuing further.

    Ascaris lumbricoides is a common parasitic disease all over the world, especially in less developed countries. Acute appendicitis related to parasitic infection is a rare condition. Parasitic infections should be kept in mind in patients who are admitted to the emergency department with acute abdomen, especially in endemic areas.

    The present study investigated the effects of acute aerobic exercise on cognitive brain functions of older adults. Twenty-four males (12 older and 12 younger adults) performed a modified flanker task during a baseline session (no exercise) and after light and moderate cycling exercise in counterbalanced order on different days while measures of task performance and the P3 component of an event-related brain potential were collected. The results indicated that, for both age groups, reaction time following moderate exercise was shorter relative to the other sessions, and P3 latencies following both light and moderate exercise were shorter compared with the baseline session. In contrast, P3 amplitude increased only following moderate exercise in younger adults. These findings suggest that light and moderate exercises improve cognitive function across the adult lifespan, although the mechanisms underlying the effects of observed acute aerobic exercise on cognitive function may be age dependent.

    Acute encephalitis is an inflammation of brain tissue that can result from activity in the central nervous system (CNS) of a number of viruses. Although the neurological and psychiatric effects of encephalitis in the acute phase of the illness are well-known (Caroff, Mann, Gliatto, Sullivan, & Campbell, 2001), larger scale studies of the pattern of neuropsychological and psychiatric impairment following recovery from the acute inflammatory phase are less apparent. This paper reports the results of neuropsychological testing with a range of standardised cognitive measures in a case series of long-term post-acute participants. Psychiatric abnormality is examined using the SCL-90-R self-report scale of distress (Derogatis, 1983). We also examined the role of emerging insight in the aetiology of depression in this population. Two clusters of cognitive dysfunction were observed, one group of primarily herpes simplex cases showing a severe generalised deficit across a number of cognitive domains and a second cluster showing a variety of more isolated disorders of executive function. Abnormally high levels of distress were reported by participants, with depression, obsessive-compulsive symptoms, interpersonal sensitivity and phobic anxiety most significantly increased. Depression was found to be least severe in those with most accurate insight into their problems. Examining the correlations between cognitive and psychiatric test results demonstrates a relationship between depression and interpersonal anxiety and specific cognitive measures. Obsessive-compulsive behaviour and phobic anxiety, however, appear to exist independently of the assessed cognitive deficits.

    Isolated left ventricular noncompaction in adults is uncommon. The most frequent clinical manifestations are heart failure due to left ventricular systolic dysfunction and supraventricular and ventricular arrhythmias, which may be sustained and associated with sudden death. Thromboembolic complications are also possible. We report the case of an adult patient with isolated left ventricular noncompaction who came to our observation because of acute cerebral ischemia, an initial presentation of the disease only rarely described.

    Background The epidemiologic characteristics of children and young adults with acute kidney injury have been described in single-center and retrospective studies. We conducted a multinational, prospective study involving patients admitted to pediatric intensive care units to define the incremental risk of death and complications associated with severe acute kidney injury. Methods We used the Kidney Disease: Improving Global Outcomes criteria to define acute kidney injury. Severe acute kidney injury was defined as stage 2 or 3 acute kidney injury (plasma creatinine level ≥2 times the baseline level or urine output <0.5 ml per kilogram of body weight per hour for ≥12 hours) and was assessed for the first 7 days of intensive care. All patients 3 months to 25 years of age who were admitted to 1 of 32 participating units were screened during 3 consecutive months. The primary outcome was 28-day mortality. Results A total of 4683 patients were evaluated; acute kidney injury developed in 1261 patients (26.9%; 95% confidence interval [CI], 25.6 to 28.2), and severe acute kidney injury developed in 543 patients (11.6%; 95% CI, 10.7 to 12.5). Severe acute kidney injury conferred an increased risk of death by day 28 after adjustment for 16 covariates (adjusted odds ratio, 1.77; 95% CI, 1.17 to 2.68); death occurred in 60 of the 543 patients (11.0%) with severe acute kidney injury versus 105 of the 4140 patients (2.5%) without severe acute kidney injury (P<0.001). Severe acute kidney injury was associated with increased use of mechanical ventilation and renal-replacement therapy. A stepwise increase in 28-day mortality was associated with worsening severity of acute kidney injury (P<0.001 by log-rank test). Assessment of acute kidney injury according to the plasma creatinine level alone failed to identify acute kidney injury in 67.2% of the patients with low urine output. Conclusions Acute kidney injury is common and is associated with poor outcomes, including increased

    Clonal cytogenetic abnormalities are found in 20-30% of patients with chronic myelomonocytic leukemia (CMML), while gene mutations are present in >90% of cases. Patients with low risk cytogenetic features account for 80% of CMML cases and often fall into the low risk categories of CMML prognostic scoring systems, but the outcome differs considerably among them. We performed targeted deep sequencing of 83 myeloid-related genes in 56 CMML patients with low risk cytogenetic features or uninformative conventional cytogenetics (CC) at diagnosis, with the aim to identify the genetic characteristics of patients with a more aggressive disease. Targeted sequencing was also performed in a subset of these patients at time of acute myeloid leukemia (AML) transformation. Overall, 98% of patients harbored at least one mutation. Mutations in cell signaling genes were acquired at time of AML progression. Mutations in ASXL1, EZH2 and NRAS correlated with higher risk features and shorter overall survival (OS) and progression free survival (PFS). Patients with SRSF2 mutations associated with poorer OS, while absence of TET2 mutations (TET2wt) was predictive of shorter PFS. A decrease in OS and PFS was observed as the number of adverse risk gene mutations (ASXL1, EZH2, NRAS and SRSF2) increased. On multivariate analyses, CMML-specific scoring system (CPSS) and presence of adverse risk gene mutations remained significant for OS, while CPSS and TET2wt were predictive of PFS. These results confirm that mutation analysis can add prognostic value to patients with CMML and low risk cytogenetic features or uninformative CC. PMID:27486981

    Purpose The frequency of RAS mutations in chronic myelomonocytic leukemia (CMML) suggests that activation of the MAPK pathway is important in CMML pathogenesis. Accordingly, we hypothesized that mutations in other members of the MAPK pathway might be overrepresented in RASwt CMML. Methods We performed next generation sequencing analysis on 70 CMML patients with known RAS mutation status using the TruSeq Amplicon Cancer Panel kit (Illumina, San Diego, CA). Results The study group included 37 men and 33 women with a median age of 67.8 years (range, 28–86 years). Forty patients were RASwt and 30 were RASmut; the latter included KRAS=17; NRAS=12; KRAS+NRAS=1. Next-generation sequencing showed 5 patients (7.1% of total group; 12.5% of RASwt group) with RASwt who had BRAF mutations. All BRAFmut patients had CMML-1; 2 (40%) with MPN-CMML and 3 with MDS-CMML. The BRAF mutations were of missense type and involved exon 11 in 1 patient and exon 15 in 4 patients. All BRAFmut patients had CMML-1 with low-risk cytogenetic findings, and none of the BRAFmut CMML cases were therapy-related. Two (40%) of the 5 patients with BRAFmut patients transformed to acute myeloid leukemia during follow up. Multivariate Cox proportional hazard regression modeling suggests that BRAFmut status is associated with overall survival (p=0.04). Additionally, the RASmut group tended to have worse OS compared to the RASwt group. Conclusion In summary, we demonstrate that a subset of patients with RASwt CMML harbors BRAF kinase domain mutations that are potentially capable of activating the MAPK signaling pathway.

    Eight groups of male adolescent and adult spontaneous hyperactive rats (SHR) were used in a dose response (saline, 0.6, 2.5, and 10 mg/kg) experiment of methylphenidate (MPD). Four different locomotor indices were recorded for 2 hours postinjection using a computerized monitoring system. Acutely, the 0.6 mg/kg dose of MPD did not elicit an increase in locomotor activity in either the adolescent or in the adult male SHR. The 2.5 and the 10.0 mg/kg doses increased activity in the adolescent and the adult rats. Chronically, MPD treatment when comparing adolescent and adult gave the following results: the 0.6 mg/kg dose of MPD failed to cause sensitization in the adolescent group but caused sensitization in the adult group, while the 2.5 and 10 mg/kg both caused sensitization in the adolescent and adult groups.

    Neutrophil elastase (NE) and proteinase 3 (PR3) differ in intracellular localization, which may reflect different trafficking mechanisms of the precursor forms when synthesized at immature stages of neutrophils. To shed further light on these mechanisms, we compared the trafficking of precursor NE (proNE) and precursor PR3 (proPR3). Like proNE [1], proPR3 interacted with CD63 upon heterologous co-expression in COS cells but endogenous interaction was not detected although cell surface proNE/proPR3/CD63 were co-endocytosed in myelomonocytic cells. Cell surface proNE/proPR3 turned over more rapidly than cell surface CD63 consistent with processing/degradation of the pro-proteases but recycling of CD63. Colocalization of proNE/proPR3/CD63 with clathrin and Rab 7 suggested trafficking through coated vesicles and late endosomes. Partial caveolar trafficking of proNE/CD63 but not proPR3 was suggested by colocalization with caveolin-1. Blocking the C-terminus of proNE/proPR3 by creating a fusion with FK506 binding protein inhibited endosomal re-uptake of proNE but not proPR3 indicating 'pro{sub C}'-peptide-dependent structural/conformational requirements for proNE but not for proPR3 endocytosis. The NE aminoacid residue Y199 of a proposed NE sorting motif that interacts with AP-3 [2] was not required for proNE processing, sorting or endocytosis in rat basophilic leukemia (RBL) cells expressing heterologous Y199-deleted proNE; this suggests operation of another AP-3-link for proNE targeting. Our results show intracellular multi-step trafficking to be different between proNE and proPR3 consistent with their differential subcellular NE/PR3 localization in neutrophils.

    Acute diarrhea is defined as an abnormally frequent discharge of semisolid or fluid fecal matter from the bowel, lasting less than 14 days. More than three millions cases of acute diarrhea, presumably due to intestinal infections, are seen in general practice every year in France. Most of the cases are benign and resolve under symptomatic treatment within 3 days, without need for biological tests or antibiotics. In special contexts (septicemic syndrome, visible blood in stools, severe dehydration, patients at risk of severe sepsis [valvulopathy]), biologic tests and probabilist antibiotic treatment are required. Hygiene, rehydration and diet recommendations are always part of the treatment of acute diarrhea, in addition to the symptomatic treatment of diarrhea and other digestive symptoms. Antibiotic-associated diarrhea is clinically benign in most cases, and attributed to transient dysbiosis of gut microbiota. In the remaining cases, diarrhea is the clinical expression of intestinal infection by Clostridium difficile, that should be treated with metronidazole, or the clinical expression of a Klebsiella oxytoca-associated colitis that usually spontaneously resolves after stopping antibiotics.

    Introduction: Acute corrosive poisonings are caused by ingestion of corrosive chemicals which are most commonly used as household agents. Intoxications with these kind of agents produce numerous and severe post-corrosive complications of the upper gastrointestinal tract. On the other hand, our experience showed that corrosive agents may also cause injuries of the respiratory system, which makes the treatment very hard and additionally complicates the severe clinical condition of the patient. Objective: The aim of the study is to show the incidence of respiratory complications in acute corrosive poisonings, the need of various clinical investigations and also the treatment and final outcome of these kind of poisoning. Methods: We retrospectively analyzed clinical records of 415 patients hospitalized and treated at the University clinic for toxicology and urgent internal medicine, in Skopje, Republic of Macedonia, in the period between 2007 and 2011. The protocol consisted of methods for analyzing the systemic complications, with an accent on the post-corrosive respiratory complications. Results: From the total number of patients even 98 (23.61%) exhibited systemic complications, from which 51 (52.04%) are respiratory complications. The majority of patients are female (n=40, 78.43%) and the most common complication is pneumonia (n=47). The youngest patient in this study was 14 and the oldest was 87 years old. Conclusion: Besides the gastrointestinal complications in the acute corrosive poisonings respiratory complications are also very often. They complicate the clinical state of patient and very often lead to fatal endings. PMID:24944527

    Bleeding disorders are commonly associated with hemato-oncologic diseases. We report a 68 years old male with a chronic myelomonocytic leukemia derived from a long lasting mielodysplastic syndrome that did not respond to treatment with Azacitidine. The patient was hospitalized due to tonic clonic seizures. A CAT scan showed a hematoma in the frontal lobe. A new assessment of hemostasis revealed an isolated deficiency of Factor X. We speculate that this deficit could be secondary to consumption due to the chronic Myelomonocytic Leukemia.

    2013-01-01

    Rationale Prior research has found that adults with attention-deficit/hyperactivity disorder (ADHD) show increased sensitivity to the impairing effects of alcohol (Weafer et al. 2009). However, these studies have focused exclusively on the ascending limb of the blood alcohol concentration (BAC) curve, and it is unclear whether these adults continue to show increased sensitivity during the later phase of the dose as BAC is declining. Objective This study tested the hypothesis that those with ADHD would display increased response to alcohol during the ascending limb of the BAC curve and less recovery from the impairing effects during the descending limb. Methods Adult social drinkers with ADHD and control adults completed measures of motor coordination, reaction time, and subjective intoxication twice following 0.64 g/kg alcohol and placebo. The measures were administered during the ascending limb of the BAC curve and again during the descending limb. Results During the ascending limb, alcohol reduced motor coordination, slowed reaction time (RT), and increased self-reports of subjective intoxication. Those with ADHD displayed greater impairment of motor coordination compared with controls. During the descending limb, controls reported diminished subjective intoxication and showed recovery from the impairing effects of alcohol on both their motor coordination and their RT. Those with ADHD showed reduced subjective intoxication and faster RT during this time, but they did not recover motor control. Conclusions The protracted time course of motor impairment in adults with ADHD despite reductions in subjective intoxication may contribute to poor decision making and diminished behavioral control in this group.

    Background Carbamazepine is used to treat chronic neuropathic pain. Objectives Evaluation of analgesic efficacy and adverse effects of carbamazepine for acute and chronic pain management (except headaches). Search methods Randomised controlled trials (RCTs) of carbamazepine in acute, chronic or cancer pain were identified, searching MEDLINE, EMBASE, SIGLE and Cochrane CENTRAL to June 2010, reference lists of retrieved papers, and reviews. Selection criteria RCTs reporting the analgesic effects of carbamazepine. Data collection and analysis Two authors independently extracted results and scored for quality. Numbers needed to treat to benefit (NNT) or harm (NNH) with 95% confidence intervals (CI) were calculated from dichotomous data for effectiveness, adverse effects and adverse event withdrawal. Issues of study quality, size, duration, and outcomes were examined. Main results Fifteen included studies (12 cross-over design; three parallel-group) with 629 participants. Carbamazepine was less effective than prednisolone in preventing postherpetic neuralgia following acute herpes zoster (1 study, 40 participants). No studies examined acute postoperative pain. Fourteen studies investigated chronic neuropathic pain: two lasted eight weeks, others were four weeks or less (mean 3 weeks, median 2 weeks). Five had low reporting quality. Ten involved fewer than 50 participants; mean and median maximum treatment group sizes were 34 and 29. Outcome reporting was inconsistent. Most placebo controlled studies indicated that carbamazepine was better than placebo. Five studies with 298 participants provided dichotomous results; 70% improved with carbamazepine and 12% with placebo. Carbamazepine at any dose, using any definition of improvement was significantly better than placebo (70% versus 12% improved; 5 studies, 298 participants); relative benefit 6.1 (3.9 to 9.7), NNT 1.7 (1.5 to 2.0).

    The purpose of this review is to examine the indications of extracorporeal membrane oxygenation (ECMO) for severe acute respiratory distress syndrome (ARDS). This technique of oxygenation has significantly increased worldwide with the H1N1 flu pandemic. The goal of ECMO is to maintain a safe level of oxygenation and controlled respiratory acidosis under protective ventilation. The enthusiasm for ECMO should not obscure the consideration for potential associated complications. Before widespread diffusion of ECMO, new trials should test the efficacy of early initiation or CO2 removal in addition to, or even as an alternative to mechanical ventilation for severe ARDS.

    Recent studies demonstrated potential of home-based telerehabilitation in older adults and individuals with mobility impairment. However limited evidence exists on feasibility of home-based telerehabilitation in older adults after hip fracture. The aims of this study were: (1) to assess impact of home-based telerehabilitation of community dwelling older adults in post-acute phase of recovery after hip fracture on mobility, psycho-behavioral factors, quality of life, and satisfaction with care; (2) to estimate acceptance of the telerehabilitation system and adherence to the exercise program. We found statistically significant improvements in exercise self-efficacy, mobility, quality of life, and patient satisfaction after 30-day hip fracture telerehabilitation. Home telerehabilitation may be a viable model for post-acute hip fracture recovery and it is warranted for further evaluation in clinical trials.

    LD50 values were determined for 57 pesticides administered by the oral or dermal route to adult male and female Sherman rats. Thirty-six of the chemicals were also tested by the oral route in one sex of weanlings. Nine pesticides tested by the oral route (bufencarb, cacodylic acid, dialifor, deltamethrin, dicamba, diquat, quintozene, phoxim, pyrazon) and four tested by the dermal route (bufencarb, chlordimeform, dichlofenthion, leptophos) were more toxic to females than to males whereas famphur and 2,4,5-T (oral route) were less toxic to females. Eighteen of the test chemicals were more toxic to the adult than to the weanling and four compounds (leptophos, methidathion, pyrazon, and sulfoxide) were more toxic to the weanling. In additional studies the variability of the LD50 value over a 1-year period was examined for two typical insecticides. Six consecutive bimonthly oral LD50 determinations for parathion and DDT in adults of both sexes indicated that the LD50 values were little affected by the time of year that the tests were done.

    Data from research on amnesia and epilepsy are equivocal with regards to the dissociation, shown in animal models, between rapid and slow long-term memory consolidation. Cancer treatments have lasting disruptive effects on memory and on brain structures associated with memory, but their acute effects on synaptic consolidation are unknown. We investigated the hypothesis that cancer treatment selectively impairs slow synaptic consolidation. Cancer patients and their matched controls were administered a novel list-learning task modelled on the Rey Auditory Verbal Learning Test. Learning, forgetting, and retrieval were tested before, and one day after patients' first chemotherapy treatment. Due to difficulties recruiting cancer patients at that sensitive time, we were only able to study 10 patients and their matched controls. Patients exhibited treatment-dependent accelerated forgetting over 24 hours compared to their own pre-treatment performance and to the performance of control participants, in agreement with our hypothesis. The number of intrusions increased after treatment, suggesting retrieval deficits. Future research with larger samples should adapt our methods to distinguish between consolidation and retrieval causes for treatment-dependent accelerated forgetting. The presence of significant accelerated forgetting in our small sample is indicative of a potentially large acute effect of chemotherapy treatment on forgetting, with potentially clinically relevant implications.

    Recent advances in acute myeloid leukemia (AML) biology and its genetic landscape should ultimately lead to more subset-specific AML therapies, ideally tailored to each patient's disease. Although a growing number of distinct AML subsets have been increasingly characterized, patient management has remained disappointingly uniform. If one excludes acute promyelocytic leukemia, current AML management still relies largely on intensive chemotherapy and allogeneic hematopoietic stem cell transplantation (HSCT), at least in younger patients who can tolerate such intensive treatments. Nevertheless, progress has been made, notably in terms of standard drug dose intensification and safer allogeneic HSCT procedures, allowing a larger proportion of patients to achieve durable remission. In addition, improved identification of patients at relatively low risk of relapse should limit their undue exposure to the risks of HSCT in first remission. The role of new effective agents, such as purine analogs or gemtuzumab ozogamicin, is still under investigation, whereas promising new targeted agents are under clinical development. In contrast, minimal advances have been made for patients unable to tolerate intensive treatment, mostly representing older patients. The availability of hypomethylating agents likely represents an encouraging first step for this latter population, and it is hoped will allow for more efficient combinations with novel agents.

    Self-reported smoking histories were collected during face-to-face interviews with 807 patients with acute leukaemia and 1593 age- and sex-matched controls. Individuals who had smoked regularly at some time during their lives were more likely to develop acute leukaemia than those who had never smoked (odds ratio (OR) = 1.2, 95% confidence interval (CI) 1.0–1.4). The association was strongest for current smokers, defined here as smoking 2 years before diagnosis (OR = 1.4, 95% CI 1.1–1.7). With respect to the numbers of years smoked, risk estimates were raised in all groups except those who had smoked for fewer than 10 years. Similarly, the odds ratio decreased as the number of years ‘stopped smoking’ increased, falling to one amongst those who had given up smoking for more than 10 years. No significant linear trends were found, however, with either the numbers of years smoked or the numbers of years stopped smoking, and no significant differences were found between AML and ALL. © 1999 Cancer Research Campaign PMID:10584886

    A twin pair affected by juvenile myelomonocytic leukemia (JMML) with the same somatic PTPN11 mutation and abnormal chromosome 7 in bone marrow samples but distinct prognostic gene expression signatures, received a matched-unrelated donor and matched-unrelated cord blood transplant, respectively. Both twins fully engrafted, but after 6 months, the twin with an acute-myeloid-like (AML-like) signature at diagnosis rejected the graft and had an autologous reconstitution. A second transplant with an unrelated 5/6-HLA-matched-loci cord blood performed after 4 months from rejection was unsuccessful. After 25 months from diagnosis, the twin with the AML-like gene expression signature died of liver failure while on progression of his JMML. The other twin, who had a non-acute-myeloid-like (non-AML-like) gene expression signature at diagnosis is in complete hematological remission with full donor chimera. This observation suggests a biological diversity of JMML also in patients with a common genetic background.

  7. Chemotherapy of acute myeloid leukaemia in adults: Medical Research Council.

    PubMed Central

    1979-01-01

    Two hundred and fifty patients with acute myeloid leukaemia (AML) were randomized between 2 regimens of chemotherapy: TRAP and BARTS III. Overall, patients randomized to TRAP, which was the more intensive of the 2 regimens, fared slightly better (P = 0.06) than those on BARTS III. However, the improvement in survival associated with more intensive chemotherapy was substantial only for patients who had favourable prognostic features at presentation, such as a normal total leucocyte count, or absence of palpable liver, or, especially, age under 40. Indeed, for patients under 40, those allocated to the more intensive regimen (TRAP) lived considerably longer than those allocated to BARTS III (P less than 0.002) while for patients over 40 there was no material difference in survival between patients on the 2 protocols. It thus appears that intensive chemotherapy is likely to be more effective when favourable prognostic features are recorded. PMID:365212

    We reported the oldest acute rheumatic fever (ARF) patient with initial attack at the age of 90 years and experience with ARF in adults in 20 years of observation. The case files of all ARF patients treated by rheumatology unit, Chiang Mai University, were reviewed. Demographic data and clinical profile were recorded and compared between patients with initial attack and patients with recurrent attack. A total of 25 patients with ARF were included. There was no different incidence of arthritis and carditis between two groups. Initial attack patients have higher incidence of prolonged PR-interval (67 vs. 12%, P = 0.049) and longer duration of admission to diagnosis (5 vs. 2 days, P = 0.05). Thirty percent presented initial attack after 30 years of age. ARF is more common in adults than previously recognized. Therefore, clinicians should be aware of this condition and include it in their differential diagnosis of the febrile patients with arthritis.

    Acute myocardial infarction (AMI) is rarely associated with antiphospholipid syndrome. The treatment of these patients is a clinical challenge. We report the observations of 2 young adults (1 woman and 1 man), admitted in our acute care unit for acute myocardial infarction (AMI). A coagulopathy work-up concludes the existence of antiphospholipid syndrome (APS) in the 2 cases. APS syndrome was considered primary in 2 cases. All patients presented an intense inflammatory syndrome (high level of CRP). Anticardiolipine was present in the 2 cases. However, anti B2 glycoprotein I antibodies were detected in only one case. Emergency percutaneous transluminal coronary angioplasty (PTCA) with direct stenting had been performed successfully only in the first case, and the follow-up was uncomplicated. Thereafter, long-term oral anticoagulant appeared to be effective. The last patient was admitted because of peripheral acute ischemia of legs. Standard electrocardiogram showed signs of previous silent anteroseptal wall myocardial infarction confirmed by echocardiography. The latter revealed an apical thrombus and a very low left ventricular ejection fraction. Amputation of the right leg was necessary because of consultation occurred too late. However, he died four weeks later. Primary antiphospholipid syndrome should be considered as a cause of acute myocardial infarction in young adults, and PTCA with anticoagulant treatment is effective for initial treatment of this complication.

    Acute hemicerebellitis, marked by headache with or without cerebellar signs, is a rare clinical entity involving a unilateral cerebellar hemisphere. The pathogenesis of acute hemicerebellitis remains unclear, and the disease rarely occurs in adults. Here, we report an 18-year-old woman who presented with a lack of coordination of the right hand and leg lasting longer than one week, following a pulsatile headache. A neurological examination disclosed ocular dysmetria, right-sided limb ataxia and slight truncal ataxia. Cerebrospinal fluid analysis showed mononuclear pleocytosis. The serology and autoimmune studies were unremarkable. Brain magnetic resonance imaging (MRI) revealed a focal signal change in the right cerebellar hemisphere and vermis. Acute hemicerebellitis was diagnosed, and the patient was treated with intravenous methylprednisolone sodium succinate and acyclovir. Subsequently, the headache resolved, and the cerebellar signs were markedly improved. Twenty days after admission, she became asymptomatic and brain MRI showed resolution of cerebellar hyperintensity on the right side. In conclusion, we identified only 6 additional patients with adult-onset acute hemicerebellitis from previous reports, highlighting the importance of recognizing this rare clinical entity. Its clinical outcome is usually favorable, but in the acute phase, attention should be directed toward clinical symptoms that are suggestive of increased intracranial pressure.

    The purpose of the present study was to examine the acute effects of resting, aerobic exercise practised alone, and aerobic exercise with active video games (AVG), on complex reaction time (CRT) and the post-exercise acute rate of perceived exertion (RPE) in young healthy adults. The experimental group was composed of 92 healthy young adults, 78 males and 13 females (age M = 21.9 ± 2.7 years) who completed two sessions, A and B. In session A, participants rode 30 min on an ergometer, while in session B they exercised for 30 min on an ergometer while playing an AVG on a Wii. The control group was composed of 30 young adults, 26 males and 4 females (age M = 21.4 ± 2.9 years) who rested for 30 min. In each session, a CRT task was performed before and after exercising or resting, and post-exercise global RPE was noted. Repeated measures general linear model (GLM) and Wilcoxon tests were performed. (1) Both aerobic exercise alone and aerobic exercise combined with AVG improved CRT, while resting did not; (2) aerobic exercise combined with AVG did not improve CRT more than aerobic exercise only; and (3) RPE was lower after aerobic exercise combined with AVG compared with aerobic exercise only. In young adults, exercise produces acute benefits on CRT, and practising exercise with AVG helps to decrease RPE.

    Acute disseminated encephalomyelitis (ADEM) is an uncommon acute, rapidly progressive autoimmune demyelinating disease of the central nervous system that is most often due to infection or immunization. Generally, it is monophasic, but there is potential for recurrence and risk for development of multiple sclerosis. Although there has been literature documenting autonomic dysreflexia and hypertensive emergency in 2 pediatric cases of ADEM, to our knowledge there has not been a case detailing paroxysmal sympathetic hyperactivity in an adult patient with ADEM. This case report describes a fulminant case of ADEM and serves to expand the list of diagnoses associated with paroxysmal sympathetic hyperactivity.

    Background Between one and two of every five hospitalized older adults have cognitive deficits, often not accurately assessed or well managed. Cognitive impairment adds substantially to the complexity of these patients’ care, places them at high risk for poor outcomes and increases the cost of health care. Methods We describe three evidence-based interventions, each capitalizing on the unique contributions of nurses and designed to improve outcomes of hospitalized older adults who have cognitive deficits. Interventions of varying intensity were compared across three hospitals (Phase I) and subsequently within the same hospitals (Phase II). All enrolled patients were screened during their index hospitalizations and cognitive deficits were communicated to relevant health care team members (Augmented Standard Care-ASC, lowest intensity). At one hospital, ASC was the only intervention. Patients at a second hospital also had care influenced by specially prepared registered nurses (Resource Nurse Care-RNC, medium intensity). Finally, patients at third hospital also received advanced practice nurse coordinated care (Transitional Care Model-TCM, higher intensity). In Phase II, newly enrolled patients at these same hospitals all received the TCM. We summarize major themes from review of multiple data sources and researcher recollections related to facilitators and barriers to implementing a complex research study. Findings Effective implementation of the three intervention strategies depended on clinician engagement and communication; degree of participation by nurses in the educational program with subsequent practice improvement; and success of advanced practice nurses in implementing the TCM with both with patients, family caregivers and clinicians. Implications Based on lessons learned in implementing complex research studies within the “real world” of clinical practice settings, recommendations focus on strengthening facilitators, minimizing barriers and gaining

    Acute abdominal pain is a common presentation in the outpatient setting and can represent conditions ranging from benign to life-threatening. If the patient history, physical examination, and laboratory testing do not identify an underlying cause of pain and if serious pathology remains a clinical concern, diagnostic imaging is indicated. The American College of Radiology has developed clinical guidelines, the Appropriateness Criteria, based on the location of abdominal pain to help physicians choose the most appropriate imaging study. Ultrasonography is the initial imaging test of choice for patients presenting with right upper quadrant pain. Computed tomography (CT) is recommended for evaluating right or left lower quadrant pain. Conventional radiography has limited diagnostic value in the assessment of most patients with abdominal pain. The widespread use of CT raises concerns about patient exposure to ionizing radiation. Strategies to reduce exposure are currently being studied, such as using ultrasonography as an initial study for suspected appendicitis before obtaining CT and using low-dose CT rather than standard-dose CT. Magnetic resonance imaging is another emerging technique for the evaluation of abdominal pain that avoids ionizing radiation.

    The outcome of patients with acute promyelocytic leukaemia (APL) has dramatically improved over the last two decades, due to the introduction of combined all-trans retinoic acid (ATRA) and chemotherapy regimens and, more recently, to the advent of arsenic trioxide (ATO). ATRA and anthracycline-based chemotherapy remains a widely used strategy, providing cure rates above 80%, but it is associated with risk of severe infections and occurrence of secondary leukaemias. ATO is the most effective single agent in APL and, used alone or in combination with ATRA or ATRA and reduced-intensity chemotherapy, results in greater efficacy with considerably less haematological toxicity. The toxic profile of ATO includes frequent, but manageable, QTc prolongation and increase of liver enzymes. Two large randomized studies have shown that ATRA + ATO is superior to ATRA + chemotherapy for newly diagnosed low-risk APL resulting in 2-4 year event-free survival rates above 90% and very few relapses. According to real world data, the spectacular progress in APL outcomes reported in clinical trials has not been paralleled by a significant improvement in early death rates, this remains the most challenging issue for the final cure of the disease.

    Although acute myeloid leukemia (AML) is primarily a disease of older adults (age ≥60 years), the optimal treatment for older adults remains largely undefined. Intensive chemotherapy is rarely beneficial for frail older adults or those with poor-risk disease, but criteria that define fitness and/or appropriateness for intensive chemotherapy remain to be standardized. Evaluation of disease-related and patient-specific factors in the context of clinical decision making has therefore been largely subjective. A uniform approach to identify those patients most likely to benefit from intensive therapies is needed. Here, we review currently available objective measures to define older adults with AML who are ineligible for intensive chemotherapy, and discuss promising investigational approaches. PMID:26697412

    BACKGROUND Falls can cause moderate to severe injuries such as hip fractures and head trauma in older adults. While declines in muscle strength and sensory function contribute to increased falls in older adults, skeletal muscle fatigue is often overlooked as an additional contributor to fall risk. The purpose of this investigation was to examine the effects of acute lower extremity muscle fatigue and age on reactive postural control in healthy adults. METHODS A sample of 16 individuals participated in this study (8 healthy older adults and 8 healthy young persons). Whole body kinematic and kinetic data were collected during anterior and posterior reproducible fall tests before (T0) and immediately after (T1) eccentric muscle fatiguing exercise, as well as after 15-minutes (T15) and 30-minutes (T30) of rest. FINDINGS Lower extremity joint kinematics of the stepping limb during the support (landing) phase of the anterior fall were significantly altered by the presence of acute muscle fatigue. Step velocity was significantly decreased during the anterior falls. Statistically significant main effects of age were found for step length in both fall directions. Effect sizes for all outcomes were small. No statistically significant interaction effects were found. INTERPRETATION Muscle fatigue has a measurable effect on lower extremity joint kinematics during simulated falls. These alterations appear to resolve within 15 minutes of recovery. The above deficits, coupled with a reduced step length, may help explain the increased fall risk in older adults. PMID:26351001

    Acute alcohol exposure has been shown to produce differential motor impairments between aged and adult rats and between adolescent and adult rats. However, the effects of acute alcohol exposure among adolescent, adult, and aged rats have yet to be systematically investigated within the same project using a dose-dependent analysis. We sought to determine the age- and dose-dependent effects of acute alcohol exposure on gross and coordinated motor performance across the rodent lifespan. Adolescent (PD 30), adult (PD 70), and aged (approximately 18 months) male Sprague-Dawley rats were tested on 3 separate motor tasks: aerial righting reflex (ARR), accelerating rotarod (RR), and loss of righting reflex (LORR). In a separate group of animals, blood ethanol concentrations (BEC) were determined at multiple time points following a 3.0 g/kg ethanol injection. Behavioral tests were conducted with a Latin square repeated-measures design in which all animals received the following doses: 1.0 g/kg or 2.0 g/kg alcohol or saline over 3 separate sessions via intraperitoneal (i.p.) injection. During testing, motor impairments were assessed on the RR 10 min post-injection and on ARR 20 min post-injection. Aged animals spent significantly less time on the RR when administered 1.0 g/kg alcohol compared to adult rats. In addition, motor performance impairments significantly increased with age after 2.0 g/kg alcohol administration. On the ARR test, aged rats were more sensitive to the effects of 1.0 g/kg and 2.0 g/kg alcohol compared to adolescents and adults. Seven days after the last testing session, animals were given 3.0 g/kg alcohol and LORR was examined. During LORR, aged animals slept longer compared to adult and adolescent rats. This effect cannot be explained solely by BEC levels in aged rats. The present study suggests that acute alcohol exposure produces greater motor impairments in older rats when compared to adolescent and adult rats and begins to establish a

    Thirty adult patients suffering from acute nonlymphocytic leukemia (ANLL) were treated according to a modified COAP regimen. Vincristine, cyclophosphamide, and prednisone were given by push injection, while cytosine arabinoside was infused over periods of 8 h. Nineteen patients (63%) achieved complete remission. Remission maintenance therapy consisted of 6-mercaptopurine daily and methotrexate twice weekly. Later in the study, COAP consolidation and reinduction was added, which improved the median duration of complete remission from 7 to 24 months. Comparison of the results with the literature shows that the modified COAP regimen is one of the most effective treatment schedules for adult ANLL.

    This review discusses the use of prognostic factors, patient and donor selection, choice of conditioning regimens, and timing of transplant. It also describes the management of Philadelphia-positive acute lymphocytic leukemia (ALL) and central nervous system disease. All aggressively treated adults with ALL should be considered for allogeneic transplantation and tissue typed at diagnosis. We further suggest that eligible patients be entered into clinical trials (that incorporate transplantation); these unselected prospective outcome data are essential to evaluate the true value of allogeneic transplantation in adults with ALL.

    Background. Frequency and impact of medical complications on short-term mortality in young patients with intracerebral hemorrhage (ICH) have gone unstudied. Methods. We reviewed data of all first-ever nontraumatic ICH patients between 16 and 49 years of age treated in our hospital between January 2000 and March 2010 to identify medical complications suffered. Logistic regression adjusted for known ICH prognosticators was used to identify medical complications associated with mortality. Results. Among the 325 eligible patients (59% males, median age 42 [interquartile range 34–47] years), infections were discovered in 90 (28%), venous thrombotic events in 13 (4%), cardiac complications in 4 (1%), renal failure in 59 (18%), hypoglycemia in 15 (5%), hyperglycemia in 165 (51%), hyponatremia in 146 (45%), hypernatremia in 91 (28%), hypopotassemia in 104 (32%), and hyperpotassemia in 27 (8%). Adjusted for known ICH prognosticators and diabetes, the only independent complication associated with 3-month mortality was hyperglycemia (plasma glucose >8.0 mmol/L) (odds ratio: 5.90, 95% confidence interval: 2.25–15.48, P < 0.001). Three or more separate complications suffered also associated with increased mortality (7.76, 1.42–42.49, P = 0.018). Conclusions. Hyperglycemia is a frequent complication of ICH in young adults and is independently associated with increased mortality. However, multiple separate complications increase mortality even further.

    Background and Purpose: The efficacy of retigabine (RGB), a positive allosteric modulator of K+ channels indicated for adjunct treatment of partial seizures, was studied in two adult models of kainic acid (KA)-induced status epilepticus to determine it’s toleratbility. Methods: Retigabine was administered systemiclly at high (5 mg/kg) and low (1–2 mg/kg) doses either 30 min prior to or 2 hr after KA-induced status epilepticus. High (1 µg/µL) and low (0.25 µg/µL) concentrations of RGB were also delivered by intrahippocampal microinjection in the presence of KA. Results: Dose-dependent effects of RGB were observed with both models. Lower doses increased seizure behavior latency and reduced the number of single spikes and synchronized burst events in the electroencephalogram (EEG). Higher doses worsened seizure behavior, produced severe ataxia, and increased spiking activity. Animals treated with RGB that were resistant to seizures did not exhibit significant injury or loss in GluR1 expression; however if stage 5–6 seizures were reached, typical hippocampal injury and depletion of GluR1 subunit protein in vulernable pyramidal fields occurred. Conclusions: RGB was neuroprotective only if seizures were significantly attenuated. GluR1 was simultaneously suppressed in the resistant granule cell layer in presence of RGB which may weaken excitatory transmission. Biphasic effects observed herein suggest that the human dosage must be carefully scrutinized to produce the optimal clinical response. PMID:26819936

    2016-01-01

    In adults, mallet finger is a traumatic zone I lesion of the extensor tendon with either tendon rupture or bony avulsion at the base of the distal phalanx. High-energy mechanisms of injury generally occur in young men, whereas lower energy mechanisms are observed in elderly women. The mechanism of injury is an axial load applied to a straight digit tip, which is then followed by passive extreme distal interphalangeal joint (DIPJ) hyperextension or hyperflexion. Mallet finger is diagnosed clinically, but an X-ray should always be performed. Tubiana's classification takes into account the size of the bony articular fragment and DIPJ subluxation. We propose to stage subluxated fractures as stage III if the subluxation is reducible with a splint and as stage IV if not. Left untreated, mallet finger becomes chronic and leads to a swan-neck deformity and DIPJ osteoarthritis. The goal of treatment is to restore active DIPJ extension. The results of a six- to eight-week conservative course of treatment with a DIPJ splint in slight hyperextension for tendon lesions or straight for bony avulsions depends on patient compliance. Surgical treatments vary in terms of the approach, the reduction technique, and the means of fixation. The risks involved are stiffness, septic arthritis, and osteoarthritis. Given the lack of consensus regarding indications for treatment, we propose to treat all cases of mallet finger with a dorsal glued splint except for stage IV mallet finger, which we treat with extra-articular pinning.

    There is evidence that an acute bout of exercise confers cognitive benefits, but it is largely unknown what the optimal mode and duration of exercise is and how cognitive performance changes over time after exercise. We compared the cognitive performance of 31 older adults using the Stroop test before, immediately after, and at 30 and 60 min after a 10 and 30 min aerobic or resistance exercise session. Heart rate and feelings of arousal were also measured before, during, and after exercise. We found that, independent of mode or duration of exercise, the participants improved in the Stroop Inhibition task immediately postexercise. We did not find that exercise influenced the performance of the Stroop Color or Stroop Word Interference tasks. Our findings suggest that an acute bout of exercise can improve cognitive performance and, in particular, the more complex executive functioning of older adults.

    We have previously demonstrated that aging reduces the compensatory vasodilator response during hypoxic exercise due to blunted nitric oxide (NO) signaling. Recent evidence suggests that NO bioavailability can be augmented by dietary nitrate through the nitrate-nitrite pathway. Thus we tested the hypothesis that acute dietary nitrate supplementation increases the compensatory vasodilator response to hypoxic exercise, particularly in older adults. Thirteen young (25 ± 1 yr) and 12 older (64 ± 2 yr) adults performed rhythmic forearm exercise at 20% of maximum voluntary contraction during normoxia and hypoxia (∼80% O2 saturation); both before (control) and 3 h after beetroot juice (BR) consumption. Forearm vascular conductance (FVC; ml·min(-1)·100 mmHg(-1)) was calculated from forearm blood flow (ml/min) and blood pressure (mmHg). Compensatory vasodilation was defined as the relative increase in FVC due to hypoxic exercise (i.e., % increase compared with respective normoxic exercise trial). Plasma nitrite was determined from venous blood samples obtained before the control trials and each of the exercise trials (normoxia and hypoxia) after BR. Consumption of BR increased plasma nitrite in both young and older adults (P < 0.001). During the control condition, the compensatory vasodilator response to hypoxic exercise was attenuated in older compared with young adults (3.8 ± 1.7% vs. 14.2 ± 1.2%, P < 0.001). Following BR consumption, compensatory vasodilation did not change in young (13.7 ± 3.3%, P = 0.81) adults but was substantially augmented in older adults (11.4 ± 2.1%, P < 0.01). Our data suggest that acute dietary nitrate supplementation increases the compensatory vasodilator response to hypoxic exercise in older but not young adults.

    Caffeine is a psychostimulant with intake through foods or beverages tending to increase from childhood through adolescence. The goals of the present study were to examine the effects of caffeine on young adolescent Long-Evans rats and to compare the motor-behavioral responses of adolescent and adult rats to acute and chronic caffeine. Adolescent rats had a biphasic dose-response to caffeine comparable to that reported for adult rats. The magnitude of the motor response to a challenge dose of caffeine (30mg/kg, ip) was similar between adolescent and adult rats. Administration of caffeine in the drinking water (1mg/ml) for a period of 2 weeks led to overall consumption of caffeine which was not significantly different between adolescents and adults when normalized to body mass. There were no impacts of caffeinated drinking water on volume of fluid consumed nor weight gain in either age group compared to age matched controls drinking non-caffeinated tap water. Following this period of caffeine consumption, return to regular drinking water (caffeine withdrawal) led to a significant decrease in baseline movement compared to caffeine-naïve rats. This effect inversion was observed for adolescents but not adults. In addition, the response of the adolescents to the challenge dose of caffeine (30mg/kg, ip) was reduced significantly after chronic caffeine consumption and withdrawal. This apparent tolerance to the caffeine challenge dose was not seen with the adults. Thus, the developing brain of these adolescents may show similar sensitivity to adults in acute caffeine exposure but greater responsiveness to adaptive changes associated with chronic caffeine consumption.

    The treatment of patients with chronic myelomonocytic leukemia (CMML) with transplant has not been optimized. We retrospectively reviewed the data for 83 consecutive patients with CMML (47 with CMML-1/2 and 36 with CMML progressed to acute myeloid leukemia) who received an allogeneic stem cell transplant at our institution between April 1991 and December 2013 to identify factors associated with improved survival and determine whether treatment with hypomethylating agents before transplant improves progression-free survival. The median age of the cohort was 57 years. Seventy-eight patients received induction treatment before transplant, with 37 receiving hypomethylating agents and 41 receiving cytotoxic chemotherapy. Patients treated with a hypomethylating agent had a significantly lower cumulative incidence of relapse at 3 years post-transplant (22%) than those treated with other agents (35%; p=0.03), whereas TRM at 1 year post-transplant did not significantly differ between the groups (27% and 30%, respectively; p=0.84). The lower relapse rate resulted in a significantly higher 3-year PFS rate in patients treated with a hypomethylating agent (43%) than in those treated with other agents (27%; p=0.04). Our data support the use of hypomethylating agents before allogeneic stem cell transplantation for patients with CMML to achieve morphologic remission and improve progression-free survival of these patients. Future studies are needed to confirm these findings. PMID:26343946

    Epidemic surveillance is an effective means to determine the characteristics of acute diarrhoea and the benefits of disease control and prevention. The epidemiological, clinical, and aetiological data of adult (aged ⩾15 years) acute diarrhoea in a general hospital in Shanghai were collected and analysed. Out of 2430 acute diarrhoea patients, 162 subjects were sampled (sample ratio 15:1). The sampled subjects had an average age (±s.d.) of 44 ± 18 years; 142 (87·7%) had a history that indicated ingestion of contaminated food; and 40 (24·7%), 54 (33·3%), and 73 (45·1%) patients had diarrhoea that was attributed to viral, bacterial, and unknown aetiological origins respectively. Viral diarrhoea is mainly prevalent during the winter and spring months, while bacterial and diarrhoea of unknown aetiology occur mainly in the summer months. The average age of the unknown aetiology group (48 ± 19 years) was significantly older than that of the viral diarrhoea group (39 ± 16 years). The number of patients with vomiting in the viral group (30·6%) was significantly higher than that in the bacterial (17·1%) and unknown aetiology (8·2%) groups. Viral and bacterial infections are the main cause of acute diarrhoea in Shanghai. However, further effective technological means are needed to improve the surveillance, control, and prevention of acute diarrhoea.

    Objective. Limited reported data have reports effects after acute ingestion of methotrexate. Treatment recommendations do not differentiate between exposure routes. Our objective was to determine the frequency of significant toxicity effects and use of therapy after methotrexate ingestion in adults. Methods. We performed a retrospective study on adult cases reported to 6 poison centers over 6 years (2000–2005) which exceed 180,000 exposures/year. Variables collected included demographics, dosages ingested, coingestions, clinical effects, and therapies with outcomes. Results. Sixty-three patients examined over the 6-year period met inclusion criteria. No patient in the series received dialysis or died. The mean dose ingested for all patients was 24 mg (range 2.5–100 mg) and the mean dose for suicidal ingestions was 47.5 mg (12.5–100 mg). The most common clinical effects were abdominal pain, oral irritation, throat irritation, nausea, dizziness, and headache. Nine patients received folinic acid and 3 patients received sodium bicarbonate. No patient developed renal failure, bone marrow suppression, seizure, or coma. No patient died or received dialysis. Conclusion. In our series of patients from 6 poison centers over six years, 63 cases of acute adult methotrexate ingestions were reported. Methotrexate toxicity from ingestion in adults was uncommon and rarely toxic. PMID:24829573

    Treatment of acute leukaemia in adult Jehovah's Witnesses (JW) is challenging because of 'a priori' refusal of most physicians to apply diagnostic and therapeutic procedures to haematological abnormalities resembling acute leukaemia. Rejection of blood transfusions by individuals of this faith is usually blamed to justify this attitude, thus leading to severe personal, medical and psychological distress related to the lack of care. We therefore intended to verify whether a standard (tailored) chemotherapy, without the use of prophylactic blood product transfusions, could be applied during treatment of acute leukaemia under such circumstances. Eleven consecutive JW adult patients with acute leukaemia, all of whom had been denied care in other institutions, were treated at the European Institute of Oncology (EIO) in Milan, Italy. Five had acute lymphoblastic leukaemia (ALL) (one bcr/abl positive), six had acute myeloid leukaemia (AML) with immunophenotype and/or cytogenetic intermediate-high risk features, except one patient with acute promyelocytic leukaemia (APML). Standard induction chemotherapy [cytosine arabinoside (ARA-C) and daunorubicin (DNR) for AML, vincristine (VCR), DNR and prednisone (PDN) for ALL, all-trans retinoic acid (ATRA) and DNR for APML] with the antracycline dose of at least 30 mg/sqm were used. All patients experienced severe anaemia after induction chemotherapy despite erythropoietin. Median haemoglobin nadir for patients with ALL and AML was 4.5 g/dL (range 1.3-6.9) and 5.1 g/dL (range 2.6-6.8), respectively. Median platelet nadir counts for all patients was 14.5 x 10(9))/L (range 1-24). One patient died during induction probably due to haemorrhage. Four of five patients with ALL achieved a complete remission (CR) (including the bcr/abl case) while among patients with AML only the one with APML achieved CR. Three patients (APML = 1 and ALL = 2) are still alive and disease-free. This small series of adult patients with leukaemia illustrates

    It is a common perception that young people do not become ill and do not pose a challenge in the unscheduled healthcare setting. The research, however, increasingly suggests that young adults and adolescents (YAAs) are a highly vulnerable group, with poorer outcomes than either older adults or children, and distinct healthcare needs. The acute medical unit (AMU) setting poses particular challenges to the care of this patient group. To improve care and patient experience, adult clinicians need to look critically at their services and seek to adapt them to meet the needs of YAAs. This requires cooperation and linkage with local paediatric and emergency services, as well as the input of other relevant stakeholder groups. Staff on AMUs also need to develop the knowledge, skills and attitudes to communicate effectively and address the developmental and health needs of YAAs and their parents/carers at times of high risk and stress.

  15. Staphylococcus aureus: is it a pathogen of acute bacterial sinusitis in children and adults?

    PubMed

    Wald, Ellen R

    2012-03-01

    Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis are the etiologic agents of acute bacterial sinusitis (ABS). Staphylococcus aureus has been an uncommon cause of ABS despite its frequent occupancy within the anterior nares. A quantitative culture of a maxillary sinus aspirate is the gold standard for determining etiology of ABS. Cultures of the middle meatus cannot be used as a surrogate for a maxillary sinus aspirate in children with ABS, although they may be used in adults if interpretation is confined to usual sinus pathogens. Recent studies highlighting S. aureus as a major pathogen in ABS should be interpreted cautiously. Most isolates in recent pediatric studies were derived from cultures of the middle meatus. The range of reported results for the incidence of S. aureus as a cause of ABS in adults is similar to the results reported for staphylococcal colonization of the middle meatus in healthy adults.

    Genomic landscapes of 92 adult and 111 pediatric patients with B-cell acute lymphoblastic leukemia (B-ALL) were investigated using next-generation sequencing and copy number alteration analysis. Recurrent gene mutations and fusions were tested in an additional 87 adult and 93 pediatric patients. Among the 29 newly identified in-frame gene fusions, those involving MEF2D and ZNF384 were clinically relevant and were demonstrated to perturb B-cell differentiation, with EP300-ZNF384 inducing leukemia in mice. Eight gene expression subgroups associated with characteristic genetic abnormalities were identified, including leukemia with MEF2D and ZNF384 fusions in two distinct clusters. In subgroup G4 which was characterized by ERG deletion, DUX4-IGH fusion was detected in most cases. This comprehensive dataset allowed us to compare the features of molecular pathogenesis between adult and pediatric B-ALL and to identify signatures possibly related to the inferior outcome of adults to that of children. We found that, besides the known discrepancies in frequencies of prognostic markers, adult patients had more cooperative mutations and greater enrichment for alterations of epigenetic modifiers and genes linked to B-cell development, suggesting difference in the target cells of transformation between adult and pediatric patients and may explain in part the disparity in their responses to treatment.

    Adolescent rats display reduced sensitivity to many dysphoria-related effects of alcohol (ethanol) including motor ataxia and sedative hypnosis, but the underlying neurobiological factors that contribute to these differences remain unknown. The cyclic adenosine monophosphate (cAMP)-dependent protein kinase A (PKA) pathway, particularly the type II regulatory subunit (RII), has been implicated in ethanol-induced molecular and behavioral responses in adults. Therefore, the current study examined cerebral cortical PKA in adolescent and adult ethanol responses. With the exception of early adolescence, PKA RIIα and RIIβ subunit levels largely did not differ from adult levels in either whole cell lysate or P2 synaptosomal expression. However, following acute ethanol exposure, PKA RIIβ P2 synaptosomal expression and activity were increased in adults, but not in adolescents. Behaviorally, intracerebroventricular administration of the PKA activator Sp-cAMP and inhibitor Rp-cAMP prior to ethanol administration increased adolescent sensitivity to the sedative-hypnotic effects of ethanol compared to controls. Sp-cAMP was ineffective in adults whereas Rp-cAMP suggestively reduced loss of righting reflex (LORR) with paralleled increases in blood ethanol concentrations. Overall, these data suggest that PKA activity modulates the sedative/hypnotic effects of ethanol and may potentially play a wider role in the differential ethanol responses observed between adolescents and adults.

    Background and Objectives There is an emerging evidence base for the use of music therapy in the treatment of severe mental illness. Whilst different models of music therapy have been developed in mental health care, none have specifically accounted for the features and context of acute in-patient settings. This review aimed to identify how music therapy is provided for acute adult psychiatric in-patients and what outcomes have been reported. Review Methods A systematic review using medical, psychological and music therapy databases. Papers describing music therapy with acute adult psychiatric in-patients were included. Analysis utilised narrative synthesis. Results 98 papers were identified, of which 35 reported research findings. Open group work and active music making for nonverbal expression alongside verbal reflection was emphasised. Aims were engagement, communication and interpersonal relationships focusing upon immediate areas of need rather than longer term insight. The short stay, patient diversity and institutional structure influenced delivery and resulted in a focus on single sessions, high session frequency, more therapist direction, flexible use of musical activities, predictable musical structures, and clear realistic goals. Outcome studies suggested effectiveness in addressing a range of symptoms, but were limited by methodological shortcomings and small sample sizes. Studies with significant positive effects all used active musical participation with a degree of structure and were delivered in four or more sessions. Conclusions No single clearly defined model exists for music therapy with adults in acute psychiatric in-patient settings, and described models are not conclusive. Greater frequency of therapy, active structured music making with verbal discussion, consistency of contact and boundaries, an emphasis on building a therapeutic relationship and building patient resources may be of particular importance.

    Adults with relapsed or refractory B-cell acute lymphoblastic leukemia have a dismal prognosis with a short median overall survival that can be measured in months. Because most patients will have chemotherapy-resistant disease, allogeneic hematopoietic stem cell transplantation remains the only potentially curative treatment. Despite advances in current management, patients continue to have poor outcomes and lack of durable responses. Thus, new therapies with alternative modes of actions are currently being investigated. Blinatumomab is a novel bispecific T-cell engager that simultaneously binds CD3-positive cytotoxic T-cells and CD19-positive B-cells, resulting in selective lysis of tumor cells. It has shown promising results in patients with relapsed or refractory acute lymphoblastic leukemia or those achieving hematologic response with persistent minimum residual disease. Future clinical trials will answer questions regarding its optimal place in the treatment paradigm. Dose-limiting toxicities include immunological toxicities and cytokine release syndrome. However, most patients tolerate the therapy relatively well. This review will focus on the pharmacology, clinical efficacy, and safety of blinatumomab in the treatment of adult B-cell acute lymphoblastic leukemia while highlighting its unique drug warnings and toxicity management.

    Introduction: Acute intoxications with corrosive substances can cause severe chemical injuries of the upper gastrointestinal tract, most often located in the mouth, pharynx, esophagus, stomach and duodenum. If a patient survives the acute phase of intoxication, regenerative response may result in esophageal and/or gastric stenosis, and increased risk of esophageal and gastric cancer. Such intoxication may be fatal due to perforation or tracheal necrosis. Enteral nutrition is a nutritional method when nutritional substances are administered through specially designed tubing placed through the nose or percutaneously, directly into the GIT. Aim: The aim of this study is to describe the methods of artificial nutrition in patients with acute corrosive intoxications and the importance of nutritional support in the treatment of these intoxications. Discussion: Nutrition in the treatment of acute corrosive intoxications is one of the most important therapeutic processes that largely contribute to faster recovery of the post-corrosive injuries of upper GIT, stabilization of biologic, immunologic and metabolic parameters, and reduction of length of stay in hospital Aim of the treatment of acute corrosive intoxications is to prevent perforation and progressive fibrosis, and esophageal and gastric stenosis. There are different and often conflicting positions, on the conservative treatment of acute corrosive intoxications in adults. Such treatment mainly consists of anti-secretory treatment, antibiotics and intensive hyper-alimentation, aiming to prevent late post-corrosive intoxications. Conclusion: It is considered that nutritional support plays a major role in maintenance of metabolic processes and prevention of severe metabolic complications that could additionally aggravate the condition and impair the treatment.

    Although regular exercise is associated with reduced cardiometabolic disease risk among overweight adults, it remains unclear whether much of the health benefits of exercise are derived from the most recent session(s) of exercise or if they are the result of adaptations stemming from weeks, months, or even years of training. The purpose of this study was to compare the effects of habitual and acute exercise on key markers of cardiometabolic disease risk in overweight adults. We compared insulin sensitivity index (ISI) using an oral glucose tolerance test, blood pressure (BP), blood lipids, and systemic inflammatory cytokines in 12 overweight to mildly obese adults (BMI: 27-34 kg/m(2)) who exercise regularly (EX; >2.5 h exercise per week) with a well-matched cohort of 12 nonexercisers (Non-EX). Baseline measurements in EX were performed exactly 3 days after exercise, whereas Non-EX remained sedentary. We repeated these measurements the day after a session of exercise in both groups. At baseline, ISI was significantly greater in EX versus Non-EX (3.1 ± 0.2 vs. 2.3 ± 0.2; p = 0.02), but BP, blood lipids, and plasma concentration of the systemic inflammatory cytokines we measured were not different between groups. Acute exercise increased ISI the next morning in Non-EX (2.3 ± 0.2 vs. 2.8 ± 0.3; p = 0.03) but not EX. As a result, ISI was similar between groups the morning after exercise. In summary, exercising regularly was accompanied by a persistent improvement in insulin sensitivity that lasted at least 3 days after exercise in overweight adults, but just one session of exercise increased insulin sensitivity among sedentary overweight adults to levels equivalent to the regular exercisers.

    Objectives To identify the viral aetiology in adult patients with severe acute respiratory infection (SARI) admitted to sentinel surveillance institutions in Bogotá in 2012. Design A cross-sectional study was conducted in which microarray molecular techniques for viral identification were used on nasopharyngeal samples of adult patients submitted to the surveillance system, and further descriptions of clinical features and relevant clinical outcomes, such as mortality, need for critical care, use of mechanical ventilation and hospital stay, were obtained. Setting Respiratory infections requiring hospital admission in surveillance centres in Bogotá, Colombia. Participants Ninety-one adult patients with acute respiratory infection (55% were female). Measurements Viral identification, intensive care unit admission, hospital stay, and mortality. Results Viral identification was achieved for 63 patients (69.2%). Comorbidity was frequently identified and mainly involved chronic pulmonary disease or pregnancy. Influenza, Bocavirus and Adenovirus were identified in 30.8%, 28.6% and 18.7% of the cases, respectively. Admission to the intensive care unit occurred in 42.9% of the cases, while mechanical ventilation was required for 36.3%. The average hospital stay was 9.9 days, and mortality was 15.4%. Antibiotics were empirically used in 90.1% of patients. Conclusions The prevalence of viral aetiology of SARI in this study was high, with adverse clinical outcomes, intensive care requirements and high mortality. PMID:26576054

    Background No studies to-date have systematically investigated insomnia symptoms among adults with sickle cell disease (SCD). The purpose of this study was to 1) describe the prevalence of insomnia symptoms and 2) identify bio-psychosocial predictors in community-dwelling adults with Sickle Cell Disease. Methods Cross-sectional analysis of baseline data from 263 African-American adults with SCD (aged 18 years or older). Measures included the Insomnia Severity Index (ISI), Center for Epidemiologic Studies in Depression scale, Urban Life Stress Scale, Brief Pain Inventory, and a chronic pain item. SCD genotype was extracted from the medical record. Results A slight majority (55%) of the sample reported clinically significant insomnia symptomatology (ISI ≥10), which suggests that insomnia symptoms are prevalent among community-dwelling African-American adults with SCD. While insomnia symptoms were associated with a number of bio-psychosocial characteristics, depressive symptoms and acute pain were the only independent predictors. Conclusion Given the high number of participants reporting clinically significant insomnia symptoms, nurses should screen for insomnia symptoms and to explore interventions to promote better sleep among adults with SCD with an emphasis on recommending treatment for pain and depression. In addition, current pain and depression interventions in this population could add insomnia measures and assess the effect of the intervention on insomnia symptomatology as a secondary outcome.

    Adolescents and young adults (AYAs, ages 15 to 40 years) with cancer have not experienced survival improvements to the same extent as younger and older patients. We compared changes in survival after myeloablative allogeneic hematopoietic cell transplantation (HCT) for acute lymphoblastic leukemia (ALL) among children (n = 981), AYAs (n = 1218), and older adults (n = 469) who underwent transplantation over 3 time periods: 1990 to 1995, 1996 to 2001, and 2002 to 2007. Five-year survival varied inversely with age group. Survival improved over time in AYAs and paralleled that seen in children; however, overall survival did not change over time for older adults. Survival improvements were primarily related to lower rates of early treatment-related mortality in the most recent era. For all cohorts, relapse rates did not change over time. A subset of 222 AYAs between the ages of 15 and 25 at 46 pediatric or 49 adult centers were also analyzed to describe differences by center type. In this subgroup, there were differences in transplantation practices among pediatric and adult centers, although HCT outcomes did not differ by center type. Survival for AYAs undergoing myeloablative allogeneic HCT for ALL improved at a similar rate as survival for children.

    2009-01-01

    Objective: Perceived impairment and psychomotor performance following acute alcohol administration in older (ages 50-74, n = 42; 22 male) and younger (ages 25-35, n = 26; 12 male) adults were investigated in this study. Method: Double-blind, placebo-controlled alcohol administration techniques were designed to produce peak levels of breath alcohol concentration consistent with an episode of social drinking (40 mg/100 ml). Behavioral measures (Trail Making Test, Forms A and B), as well as measures of self-reported perceived intoxication and impairment, were administered on the ascending and descending limbs at common time points after beverage ingestion. Results: Results indicated that psychomotor performance differences did not parallel self-reported levels of perceived impairment. Relative to younger adults, older adults exhibited performance deficits on the ascending limb while simultaneously reporting less perceived impairment. Conversely, on the descending limb, older adults who received alcohol reported more perceived impairment than did those who received placebo, although psychomotor performance between these two groups of older drinkers did not differ. For younger participants, a moderate dose of alcohol facilitated performance on the ascending limb; however, these differences were not reflected on the descending limb. Conclusions: These results reinforce the common knowledge that self-reported measures may not provide an accurate reflection of performance outcomes and, importantly, that older adults may be impaired even under a moderate dose of alcohol, although they may not be aware (i.e., report) of this impairment.

    In contrast to acute lymphoblastic leukemia in children, adult cases of this disease are associated with a very poor prognosis. In order to ascertain whether the frequencies and patterns of submicroscopic changes, identifiable with single nucleotide polymorphism array analysis, differ between childhood and adult acute lymphoblastic leukemia, we performed single nucleotide polymorphism array analyses of 126 adult cases, the largest series to date, including 18 paired diagnostic and relapse samples. Apart from identifying characteristic microdeletions of the CDKN2A, EBF1, ETV6, IKZF1, PAX5 and RB1 genes, the present study uncovered novel, focal deletions of the BCAT1, BTLA, NR3C1, PIK3AP1 and SERP2 genes in 2-6% of the adult cases. IKZF1 deletions were associated with B-cell precursor acute lymphoblastic leukemia (P=0.036), BCR-ABL1-positive acute lymphoblastic leukemia (P<0.001), and higher white blood cell counts (P=0.005). In addition, recurrent deletions of RASSF3 and TOX were seen in relapse samples. Comparing paired diagnostic/relapse samples revealed identical changes at diagnosis and relapse in 27%, clonal evolution in 22%, and relapses evolving from ancestral clones in 50%, akin to what has previously been reported in pediatric acute lymphoblastic leukemia and indicating that the mechanisms of relapse may be similar in adult and childhood cases. These findings provide novel insights into the leukemogenesis of adult acute lymphoblastic leukemia, showing similarities to childhood disease in the pattern of deletions and the clonal relationship between diagnostic and relapse samples, but with the adult cases harboring additional aberrations that have not been described in pediatric acute lymphoblastic leukemia.

    Bench press exercise, which involves repetitive lifting of weights to full arm extension while lying supine on a narrow bench, has been associated with complications ranging in acuity from simple pectoral muscle strain, to aortic and coronary artery dissection. A 39-year-old man, physically fit and previously asymptomatic, presented with acute chest pain following bench press exercise. Diagnostic evaluation led to the discovery of critical multivessel coronary occlusive disease, and subsequently, highly elevated levels of lipoprotein (a). Judicious use of ancillary testing may identify the presence of “high-risk” conditions in a seemingly “low-risk” patient. Emergency department evaluation of the young adult with acute chest pain must take into consideration an extended spectrum of potential etiologies, so as to best guide appropriate management.

    Accessing timely acute medical care is a challenge for older adults. This article describes an innovative healthcare model that uses high-intensity telemedicine services to provide rapid acute care for older adults without requiring them to leave their senior living community (SLC) residences. This program, based in a primary care geriatrics practice that cares for SLC residents, is designed to offer acute care through telemedicine for complaints that are felt to need attention before the next available outpatient visit but not to require emergency department (ED) resources. This option gives residents access to care in their residence. Measures used to evaluate the program include successful completion of telemedicine visits, satisfaction of residents and caregivers with telemedicine care, and site of care that would have been recommended had telemedicine been unavailable. During the first 2 years of the program's operation, 281 of 301 requested telemedicine visits were completed successfully. Twelve residents were sent to an ED for care after the telemedicine visit. Ninety-four percent of residents reported being satisfied or very satisfied with telemedicine care. Had telemedicine not been available, residents would have been sent to an ED (48.1%) or urgent care center (27.0%) or been scheduled for an outpatient visit (24.4%). The project demonstrated that high-intensity telemedicine services for acute illnesses are feasible and acceptable and can provide definitive care without requiring ED or urgent care use. Continuation of the program will require evaluation demonstrating equal or better resident-level outcomes and the development of sustainable business models.

    Background: Acute influenza-associated encephalopathy/encephalitis (IAE) in adults is a rare but well-known complication of influenza virus infection. The diagnosis is difficult to make due to the absence of distinctive clinical symptoms and validated diagnostic criteria. We present an illustrative case and a case review on acute IAE in adults. Methods: We performed a Medline search of the English literature using the terms influenz*, encephal* and adult, and constructed a database of detailed descriptions of patients with influenza virus infection with influenza-like symptoms at the onset of neurological symptoms. Results: A total of 44 patients were included. Confusion and seizures were the most prevalent neurological symptoms, present in 12 (27 %) and 10 (23 %) patients, respectively. Magnetic resonance imaging (MRI) was performed in 21 patients and anomalies were found in 13 (62 %), with lesions located throughout the brain. Influenza virus RNA was detected in cerebrospinal fluid (CSF) in 5 (16 %) of 32 patients. Eight (18 %) of the forty-four patients died. The benefits of antiviral and immunomodulatory therapy have not been well studied. Discussion: Our results show that many different neurological symptoms can be present in patients with acute onset IAE. Therefore, the diagnosis should be considered in patients with fever and neurological symptoms, especially during the influenza season. Laboratory diagnosis consists of demonstration of influenza virus RNA in brain tissue, CSF or respiratory samples, and demonstration of intrathecal antibody production against influenza virus. The presence of brain lesions in MRI and influenza virus in CSF appear to be of prognostic value. PMID:28348797

    We report a case of transverse myelopathy in a 31 year old white man with acute lymphoblastic leukemia, subtype L3 (ALL-L3). This is a severe form of leukemia that affects children more often than adults. Less than 1% of leukemic patients develop neurologic complication in the spinal cord. The symptomatology in the present case started with back pain, flaccid paraplegia, and loss of sensibility and vegetative functions below the lesion. The etiologic diagnostic was obtained through peripheral blood study, bone marrow cytology, cerebrospinal fluid analysis and magnetic resonance image of the dorsal cord. The antileukemic treatment with specific drugs had no influence on the fatal outcome of the disease.

    Mineralocorticoid receptor (MR) activation by aldosterone may regulate vascular function in health or contribute to vascular dysfunction in cardiovascular disease. Whether the effects are beneficial or detrimental to vascular function appear to be dependent on the integrity of the vascular endothelium and whether the responses are short-term or chronic. Acute modulation of MR activation has resulted in conflicting outcomes on vascular function in young healthy adults. Little is known about the vascular role of aldosterone and MR activation in healthy human aging. The primary objective of this study was to examine whether acute inhibition of MR by the selective antagonist eplerenone, influences vascular function in healthy older adults. We performed a randomized, double-blind, placebo-controlled crossover study in 22 adults (61±1 years; mean±SE, 53-79 years) who were free from overt clinical cardiovascular disease. We measured brachial artery flow-mediated endothelium-dependent dilation and endothelium-independent dilation to sublingual nitroglycerin (0.4 mg) following eplerenone (100 mg/dose, 2 doses, 24h between doses) or placebo. In response to acute MR antagonism, flow-mediated dilation decreased by 19% (from 6.9±0.5 to 5.6±0.6%, P=0.02; placebo vs. eplerenone). Endothelial nitric oxide synthase (eNOS) activity also decreased following MR antagonism based on the ratio of phosphorylated eNOS(Ser1177) to total eNOS (1.53±0.08 vs. 1.29±0.06, P=0.02). Nitroglycerin-induced dilation and blood pressure were unaffected (nitroglycerin-induced dilation: 21.9±1.9 vs. 21.0±1.5%, P=0.5 and systolic/diastolic blood pressure: 135/77±4/2 vs. 134/77±4/2 mmHg, P≥0.6). In conclusion, acute MR antagonism impairs vascular endothelial function in healthy older adults without influencing vascular smooth muscle responsiveness to exogenous nitric oxide or blood pressure.

    31 adults suffering from acute leukemia were followed for a period of more than 5 years after achieving complete remission. Maintenance chemotherapy consisted of antimetabolite treatment (mercaptopurine + methotrexate) as well as COAP reinduction every 3 months. Chemotherapy was stopped if the first complete remission lasted for 3 years ("long term remission"). This was the case in 8 out of 31 remission patients (26%). Analysis of hematological parameters at diagnose for long term remission patients revealed that the initial leukocyte count was of prognostic significance.

    The quality of social relationships may contribute to variations in biological stress responses, thereby affecting health risk. The association between an important indicator of social relationships, adult attachment style, and cortisol has been relatively unexplored. The present study examined adult romantic attachment style and cortisol responses to acute laboratory stress. Salivary cortisol was measured in response to two behavioural tasks, a colour/word interference task and mirror tracing task, in 498 healthy men and women from the Heart Scan study, a subsample of the Whitehall II cohort. Participants were classified as secure, fearful, preoccupied or dismissive on the basis of responses to the Relationship Questionnaire. Cortisol output was lowest in the fearful group, followed by the preoccupied group, with both secure and dismissive groups having higher levels. The results from this study tentatively support the proposition that attachment style is a factor in determining the manifestation of HPA dysregulation.

    The purpose of this descriptive pilot study was to describe sleep characteristics of hospitalized older adults and the nighttime environmental noise and light they encountered. Study participants included patients in an acute care setting; actigraphy and light and sound meters were used to measure the variables. Mean sleep time was 215 minutes, and the average sleep efficiency was 44.72%. Nighttime sleep was fragmented into 5 to 38 intervals of 15 to 24 minutes, with frequent awakenings. Mean light levels were 6.14 lux, with peak intensities of 59.68 lux lasting 95 minutes each night. Mean sound levels were 52.87 dB(A). Sleep was markedly impaired in an environment of elevated light and sound levels. Understanding the role of noise and light in the sleep efficiency of ill older adults can help nurses identify sources of noise and light and initiate sleep improvement protocols.

    The survival rate for childhood acute lymphoblastic leukemia (ALL) is greater than 80%. However, many of these survivors develop long-term chronic health conditions, with a relatively common late effect being neurocognitive dysfunction. Although neurocognitive impairments have decreased in frequency and severity as treatment has evolved, there is a subset of survivors in the current treatment era that are especially vulnerable to the neurotoxic effects of ALL and its treatment. Additionally, little is known about long-term brain development as survivors mature into adulthood. A recent study by Zeller et al. compared neurocognitive function and brain volume in 130 adult survivors of childhood ALL to 130 healthy adults matched on age and sex. They identified the caudate as particularly sensitive to the neurotoxic effects of chemotherapy. We discuss the implications and limitations of this study, including how their findings support the concept of individual vulnerability to ALL and its treatment.

    Background The aetiology of severe gastroenteritis leading to hospitalisation in adults frequently remains unclear. Our objective was to study the causes and characteristics of community-acquired, acute gastroenteritis in adult hospitalized patients to support the clinical management of these patients. Methods From August 2005 to August 2007, we conducted a prospective cohort study among patients ≥18 y hospitalized with community-acquired gastroenteritis in a university hospital in Berlin, Germany. Stool specimens were examined for 26 gastrointestinal pathogens, supplemented by serologic tests for antibodies to Campylobacter spp., Yersinia spp., and Entamoeba histolytica. Patient data on demographics and clinical presentation were recorded and analyzed. Coexisting medical conditions were assessed using the Charlson Comorbidity Index score. Results Of 132 patients presenting with acute community-acquired gastroenteritis, 104 were included in the study. A non-infectious aetiology was diagnosed in 8 patients (8%). In 79 (82%) of the remaining 96 patients at least one microorganism was identified. Campylobacter spp. (35%) was detected most frequently, followed by norovirus (23%), Salmonella spp. (20%), and rotavirus (15%). In 46% of the patients with Campylobacter spp. infection, the diagnosis was made solely by serology. More than one pathogen was found in seventeen (22%) patients. Simultaneous infection was significantly more likely in patients with rotavirus and salmonella infections (RR 3.6; 95% CI: 1.8–7.4; RR 2.5; 95%CI: 1.2–5.5). Length of hospital stay (median: 5.5 days) was independent of the pathogen, but was associated with coexisting medical conditions (OR 4,8; 95%CI:2,0–11,6). Conclusion Known enteric pathogens were detected in 82% of adult patients who were hospitalized with acute gastroenteritis. We found that currently used culture-based methods may miss a substantial proportion of Campylobacter infections, and additional serological testing for

    Each year in the United States, nearly 70 000 individuals between the ages of 15 and 40 years are diagnosed with cancer. Although overall cancer survival rates among pediatric and older adult patients have increased in recent decades, there has been little improvement in survival of adolescent and young adult (AYA) cancer patients since 1975 when collected data became adequate to evaluate this issue. In 2006, the AYA Oncology Progress Review Group made recommendations for addressing the needs of this population that were later implemented by the LIVESTRONG Young Adult Alliance. One of their overriding questions was whether the cancers seen in AYA patients were biologically different than the same cancers in adult and/or pediatric patients. On June 9-10, 2009, the National Cancer Institute (NCI) and the Lance Armstrong Foundation (LAF) convened a workshop in Bethesda, MD, entitled "Unique Characteristics of AYA Cancers: Focus on Acute Lymphocytic Leukemia (ALL), Breast Cancer and Colon Cancer" that aimed to examine the current state of basic and translational research on these cancers and to discuss the next steps to improve their prognosis and treatment.

    Coronary artery aneurysms that occur in 25% of untreated Kawasaki disease (KD) patients may remain clinically silent for decades and then thrombose resulting in myocardial infarction. Although KD is now the most common cause of acquired heart disease in children in Asia, the United States, and Western Europe, the incidence of KD in Egypt is unknown. We tested the hypothesis that young adults in Egypt presenting with acute myocardial ischemia may have coronary artery lesions because of KD in childhood. We reviewed a total of 580 angiograms of patients ≤40 years presenting with symptoms of myocardial ischemia. Coronary artery aneurysms were noted in 46 patients (7.9%), of whom 9 presented with myocardial infarction. The likelihood of antecedent KD as the cause of the aneurysms was classified as definite (n = 10), probable (n = 29), or equivocal (n = 7). Compared with the definite and probable groups, the equivocal group had more traditional cardiovascular risk factors, smaller sized aneurysms, and fewer coronary arteries affected. In conclusion, in a major metropolitan center in Egypt, 6.7% of adults aged ≤40 years who underwent angiography for evaluation of possible myocardial ischemia had lesions consistent with antecedent KD. Because of the unique therapeutic challenges associated with these lesions, adult cardiologists should be aware that coronary artery aneurysms in young adults may be because of missed KD in childhood.

    There is a paucity of epidemiological data on chronic myeloproliferative disorders and myelodysplastic syndromes (MDS), while subtypes of acute myeloid leukemia (AML) are rarely defined. We identified 2,112 adult myeloid malignancies in the South Thames area between 1999 and 2000. The incidence (European standard population) of AML was 3.00/100,000, that of MDS 3.47/100,000, chronic myelomonocytic leukemia (CMML) 0.46/100,000, idiopathic myelofibrosis (IMF) 0.37/100,000, polycythemia vera (PV) 1.08/100,000, primary thrombocythemia (PT) 1.65/100,000 and chronic myeloid leukemia (CML) 1.09/100,000. The 3-year survival for AML was 15%, MDS 45%, CMML 29%, IMF 48%, PV 80%, PT 81% and CML 50% We believe this study reflects the true incidence and outcome of myeloid malignancies in South East England.

    Traumatic brain injury (TBI) has been known to be the leading cause of breakdown and long-term disability in people under 45 years of age. This study highlights the effective factors on post-traumatic (PT) linguistic disorder and relations between linguistic and cognitive function after trauma in adults with acute TBI. A cross-sectional design was employed to study 60 post-TBI hospitalized adults aged 18-65 years. Post-traumatic (PT) linguistic disorder and cognitive deficit after TBI were respectively diagnosed using the Persian Aphasia Test (PAT) and Persian version of Mini-Mental State Examination (MMSE) at discharge. Primary post-resuscitation consciousness level was determined using the Glasgow Coma Scale (GCS). Paracilinical data was obtained by CT scan technique. Multiple logistic regression analysis illustrated that brain injury severity was the first powerful significant predictor of PT linguistic disorder after TBI and frontotemporal lesion was the second. It was also revealed that cognitive function score was significantly correlated with score of each language skill except repetition. Subsequences of TBI are more commonly language dysfunctions that demand cognitive flexibility. Moderate, severe and fronto-temporal lesion can increase the risk of processing deficit in linguistic macrostructure production and comprehension. The dissociation risk of cortical and subcortical pathways related to cognitive-linguistic processing due to intracranial lesions can augment possibility of lexical-semantic processing deficit in acute phase which probably contributes to later cognitive-communication disorder.

    Previous research has shown that neonatal handling has prolonged protective effects associated with stress resilience and aging, yet little is known about its effect on stress-induced modulation of infectious disease. We have previously demonstrated that social disruption stress exacerbates the acute and chronic phases of the disease when applied prior to Theiler's virus infection (PRE-SDR) whereas it attenuates disease severity when applied concurrently with infection (CON-SDR). Here, we asked whether neonatal handling would protect adult mice from the detrimental effects of PRE-SDR and attenuate the protective effects of CON-SDR on Theiler's virus infection. As expected, handling alone decreased IL-6 and corticosterone levels, protected the non-stressed adult mice from motor impairment throughout infection and reduced antibodies to myelin components (PLP, MBP) during the autoimmune phase of disease. In contrast, neonatal handling X PRE/CON-SDR elevated IL-6 and reduced corticosterone as well as increased motor impairment during the acute phase of the infection. Neonatal handling X PRE/CON-SDR continued to exacerbate motor impairment during the chronic phase, whereas only neonatal handling X PRE-SDR increased in antibodies to PLP, MOG, MBP and TMEV. Together, these results imply that while handling reduced the severity of later Theiler's virus infection in non-stressed mice, brief handling may not be protective when paired with later social stress.

    Objectives. Acute acquired comitant esotropia (AACE) can be a diagnostic challenge for ophthalmologists and neurologists because of its association with neurological pathologies. Our study describes a series of adult patients with AACE of undetermined etiology. Methods. Data on the clinical findings of patients presented with AACE of undetermined etiology with a minimum follow-up of 1 year were retrieved from the medical records and the results analyzed. Results. A series of 9 esotropia cases (age range: 20–43 years) was reviewed. All patients had full duction and versions, without an A-pattern or V-pattern. All patients had esotropia for distance and near. Neurological evaluation in all cases was normal. Among patients, 3 were treated with prisms, 4 were treated with strabismus surgery, and 1 was treated with botulinum toxin injections; 1 patient declined treatment. In treated patients posttreatment sensory testing indicated restoration of binocularity that remained stable throughout follow-up of 1–9 years. The patient that declined treatment had binocular function with base-out prisms. Conclusion. Acute onset esotropia may be seen without a neurological pathology in adults. Good motor and sensory outcomes can be achieved in these patients with AACE of undetermined etiology via surgical and nonsurgical methods. PMID:28018672

    The intraosseous (IO) access initiative at an urban university adult level 1 trauma center began from the need for a more expeditious vascular access route to rescue patients in extremis. The goal of this project was a multidisciplinary approach to problem solving to increase access of IO catheters to rescue patients in all care areas. The initiative became a collaborative effort between nursing, physicians, and pharmacy to embark on an acute care endeavor to standardize IO access. This is a descriptive analysis of processes to effectively develop collaborative strategies to navigate hospital systems and successfully implement multilayered initiatives. Administration should empower nurse to advance their practice to include IO for patient rescue. Intraosseous access may expedite resuscitative efforts in patients in extremis who lack venous access or where additional venous access is required for life-saving therapies. Limiting IO dwell time may facilitate timely definitive venous access. Continued education and training by offering IO skill laboratory refreshers and annual e-learning didactic is optimal for maintaining proficiency and knowledge. More research opportunities exist to determine medication safety and efficacy in adult patients in the acute care setting.

    The prescription of methylphenidate (MPH) has dramatically increased in this decade for attention deficit hyperactivity disorder (ADHD) treatment. The action mechanism of MPH is not completely understood and studies have been demonstrated that MPH can lead to neurochemical adaptations. Superoxide radical anion is not very reactive per se. However, severe species derived from superoxide radical anion mediate most of its toxicity. In this study, the superoxide level in submitochondrial particles was evaluated in response to treatment with MPH in the age-dependent manner in rats. MPH was administrated acutely or chronically at doses of 1, 2 or 10 mg/kg i.p. The results showed that the acute administration of MPH in all doses in young rats increased the production of superoxide in the cerebellum and only in the high dose (10mg/kg) in the hippocampus, while chronic treatment had no effect. However, acute treatment in adult rats had no effect on production of superoxide, but chronic treatment decreased the production of superoxide in the cerebellum at the lower doses. Our data suggest that the MPH treatment can influence on production of superoxide in some brain areas, but this effect depends on age of animals and treatment regime with MPH.

    The aim of the present study was to quantify the severity of acute illness in patients with tick-borne encephalitis and to ascertain this approach by comparing it to standard clinical assessment. We designed scoring system for quantification of the severity of acute illness in patients with tick-borne encephalitis. Certain number of points was allotted to the presence, intensity, and duration of individual symptoms/signs. According to the obtained score the disease was classified as mild, moderate, and severe. Tick-borne encephalitis was assessed clinically as mild when only signs/symptoms of meningeal involvement were found, moderate in case of monofocal neurological signs and/or mild to moderate signs/symptoms of central nervous system dysfunction, and severe in patients with multifocal neurological signs and/or symptoms of severe dysfunction of central nervous system. By designed scoring system 282 adult patients, 146 males and 136 females, average aged 52.2 ± 15.5 years (range 15–82 years), with confirmed tick-borne encephalitis, were prospectively assessed. In 279/282 (98.9%) patients the severity according to clinical assessment matched with the score ranges for mild, moderate, and severe disease. The proposed approach enables precise and straightforward appraisal of the severity of acute illness and could be useful for comparison of findings within/between study groups. PMID:24895617

    Background: Nifuroxazide is well known and often used anti-diarrhoeal medicine which has been pushed back from routine practice in recent years and often replaced with probiotics. Even probiotics are accepted and placed in some therapeutic guidelines for diarrhoea treatment, there are no enough evidence for its effectiveness and no comparative efficacy data with nifuroxazide in treatment of acute diarrhea. Patients and Methods: In open, prospective observational study, the efficacy and safety of nifuroxazide were compared with a probiotic containing lactic acid bacteria in the treatment of acute diarrhoea. A total number of 169 adult patients were included in this study, who administered nifuroxazide in the dose of 200 mg/4 times a day, while they took preparation containing lactic acid bacteria (1,2 x 107 live lyophilised lactic-acid bacteria) three times a day for three days. Results: Mean time to last unformed stool (TLUS) in a group which was treated with nifuroxazide was two days, while it took five days for the stool normalisation in the group using probiotic (p=0.0001). Conclusions: Orally administered nifuroxazide has demonstrated better efficiency as compared to probiotic in treating acute diarrhoea, and both medicines have shown the same safety and tolerance in this study.

    Background Dengue is an emerging infectious disease of global significance. Suspected dengue, especially in children in Nicaragua’s heavily-urbanized capital of Managua, has been well documented, but unsuspected dengue among children and adults with undifferentitated fever has not. Methodology/Principal Findings To prospectively study dengue in semi-urban and rural western Nicaragua, we obtained epidemiologic and clinical data as well as acute and convalescent sera (2 to 4 weeks after onset of illness) from a convenience sample (enrollment Monday to Saturday daytime to early evening) of consecutively enrolled patients (n = 740) aged ≥ 1 years presenting with acute febrile illness. We tested paired sera for dengue IgG and IgM and serotyped dengue virus using reverse transcriptase-PCR. Among 740 febrile patients enrolled, 90% had paired sera. We found 470 (63.5%) were seropositive for dengue at enrollment. The dengue seroprevalance increased with age and reached >90% in people over the age of 20 years. We identified acute dengue (serotypes 1 and 2) in 38 (5.1%) patients. Only 8.1% (3/37) of confirmed cases were suspected clinically. Conclusions/Significance Dengue is an important and largely unrecognized cause of fever in rural western Nicaragua. Since Zika virus is transmitted by the same vector and has been associated with severe congenital infections, the population we studied is at particular risk for being devastated by the Zika epidemic that has now reached Central America.

    OBJECTIVE: To systematically assess the effect of the adjunctive administration of corticosteroids in the treatment of acute bacterial meningitis. METHODS: We performed a systematic review and meta-analysis by searching several databases for reports (published from January 1966 through February 2008) of placebo-controlled randomized trials of corticosteroid use in the treatment of adolescents and adults with acute bacterial meningitis. We used random-effects models. Sources of heterogeneity were explored by preplanned subgroup analyses. RESULTS: The 4 eligible trials (published between 1999 and 2007) were of high methodological quality and included 1261 adult patients. Overall, the short-term mortality rate associated with corticosteroid administration was not significantly lower than that associated with placebo (relative risk [RR], 0.81; 95% confidence interval [CI], 0.54-1.20; I2=54%). A significant interaction was found between the effect of corticosteroids and the income status of the country (P=.02) and the prevalence of infection with human immunodeficiency virus (HIV) among study populations (P=.03). The administration of corticosteroids resulted in a lower short-term mortality rate than did the administration of placebo in high-income countries (pooled RR, 0.5; 95% CI, 0.27-0.92; I2=0%) and in the studies with a low prevalence of infection with HIV (RR, 0.66; 95% CI, 0.44-0.99; I2=0%). In studies from high-income countries, the number needed to treat with corticosteriods to prevent 1 death and 1 neurologic sequela was 12.5 (95% CI, 7.1-100.0) and 11.0 (95% CI, 5.6-100.0), respectively. CONCLUSION: Our meta-analysis suggests that the adjunctive administration of corticosteroids is beneficial in the treatment of adolescents and adults with bacterial meningitis in patient populations similar to those seen in high-income countries and in areas with a low prevalence of HIV infection.

    2013-06-01

    Purpose: Efficacy and acute toxicity of proton craniospinal irradiation (p-CSI) were compared with conventional photon CSI (x-CSI) for adults with medulloblastoma. Methods and Materials: Forty adult medulloblastoma patients treated with x-CSI (n=21) or p-CSI (n=19) at the University of Texas MD Anderson Cancer Center from 2003 to 2011 were retrospectively reviewed. Median CSI and total doses were 30.6 and 54 Gy, respectively. The median follow-up was 57 months (range 4-103) for x-CSI patients and 26 months (range 11-63) for p-CSI. Results: p-CSI patients lost less weight than x-CSI patients (1.2% vs 5.8%; P=.004), and less p-CSI patients had >5% weight loss compared with x-CSI (16% vs 64%; P=.004). p-CSI patients experienced less grade 2 nausea and vomiting compared with x-CSI (26% vs 71%; P=.004). Patients treated with x-CSI were more likely to have medical management of esophagitis than p-CSI patients (57% vs 5%, P<.001). p-CSI patients had a smaller reduction in peripheral white blood cells, hemoglobin, and platelets compared with x-CSI (white blood cells 46% vs 55%, P=.04; hemoglobin 88% vs 97%, P=.009; platelets 48% vs 65%, P=.05). Mean vertebral doses were significantly associated with reductions in blood counts. Conclusions: This report is the first analysis of clinical outcomes for adult medulloblastoma patients treated with p-CSI. Patients treated with p-CSI experienced less treatment-related morbidity including fewer acute gastrointestinal and hematologic toxicities.

    Because increasing numbers of nasopharyngeal swab specimens from adult patients with acute respiratory illness (ARI) are being tested by respiratory virus (RV) multiplex reverse transcriptase PCR (RVM-RT-PCR), multiple RV detection (MRVD) is being encountered more frequently. However, the clinical relevance of MRVD in adult patients has rarely been evaluated. The clinical characteristics of hospitalized adult patients with ARI and MRVD by RVM-RT-PCR tests were compared to those of patients with single RV detection (SRVD) during a single year at a tertiary care center. MRVD was observed in 26 of the 190 adult patients (13.7%). The patients with MRVD had a higher incidence of chronic lung disease than the patients with SRVD (34.6% versus 15.9%, crude odds ratio [OR]=2.81, 95% confidence interval [CI]=1.13 to 6.98, P=0.03). Although the former were more likely than the latter to receive mechanical ventilation (19.2% versus 6.7%, crude OR=3.31, 95% CI=1.05 to 10.47, P=0.049), the length of hospital stay (median, 7 versus 6.5 days; P=0.66), and the in-hospital mortality rate (7.7% versus 4.3%, crude OR=1.87, 95% CI=0.37 to 9.53, P=0.35) were not different between the two groups. In multivariate analysis, chronic lung disease was associated with MRVD (adjusted OR=3.08, 95% CI=1.12 to 8.46, P=0.03). In summary, it was not uncommon to encounter adult patients with ARI and MRVD by RVM-RT-PCR tests of nasopharyngeal swab specimens. MRVD was associated with chronic lung disease rather than the severity of the ARI.

    Discovery of non-invasive diagnostic and predictive biomarkers for acute rejection in liver transplant patients would help to ensure the preservation of liver function in the graft, eventually contributing to improved graft and patient survival. We evaluated selected cytokines and chemokines in the sera from liver transplant patients as potential biomarkers for acute rejection, and found that the combined detection of IL-10, IL-17, and CXCL10 at 1-2 weeks post-operation could predict acute rejection following adult liver transplantation with 97% specificity and 94% sensitivity.

    The purpose of the paper is to compare the results of two studies in which the respiratory responses of children and adults to acute ozone (O/sub 3/) exposure were measured. Forty-two 18-30 year old males were exposed for 2.5 hours in a controlled environmental chamber to either 0.0 or 0.12 ppm O3 while performing intermittent heavy exercise. Twenty-two 8-11 year old males were exposed in a similar manner to both air and 0.12 ppm O3. Measures of respiratory symptoms and function were made before and after exposure. Adults experienced an increase in the symptom cough and decrements in forced vital capacity and some measures of forced expiratory flow. Children experienced similar decrements in pulmonary function, but had no increase in symptoms. The authors concluded that as measured by pulmonary function children appear to be no more responsive to O3 exposure than are adults and may experience fewer symptoms.

  19. Best Practices in Adolescent and Young Adult Patients with Acute Lymphoblastic Leukemia: A Focus on Asparaginase.

    The inclusion of asparaginase in chemotherapy regimens to treat acute lymphoblastic leukemia (ALL) has had a positive impact on survival in pediatric patients. Historically, asparaginase has been excluded from most treatment protocols for adolescent and young adult (AYA) patients because of perceived toxicity in this population, and this is believed to have contributed to poorer outcomes in these patients. However, retrospective analyses over the past 12 years have shown that 2-, 5-, and 7-year overall survival of AYA patients is significantly improved with pediatric versus adult protocols. The addition of asparaginase to adult protocols yielded high rates of first remission and improved survival. However, long-term survival remains lower compared with what has been seen in pediatrics. The notion that asparaginase is poorly tolerated by AYA patients has been challenged in multiple studies. In some, but not all, studies, the incidences of hepatic and pancreatic toxicities were higher in AYA patients, whereas the rates of hypersensitivity reactions did not appear to differ with age. There is an increased risk of venous thromboembolic events, and management with anti-coagulation therapy is recommended. Overall, the risk of therapy-related mortality is low. Together, this suggests that high-intensity pediatric protocols offer an effective and tolerable approach to treating ALL in the AYA population.

    Because a pediatric-inspired Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL) protocol yielded a markedly improved outcome in adults with Philadelphia chromosome-negative ALL, we aimed to reassess the role of allogeneic stem cell transplantation (SCT) in patients treated in the GRAALL-2003 and GRAALL-2005 trials. In all, 522 patients age 15 to 55 years old and presenting with at least 1 conventional high-risk factor were candidates for SCT in first complete remission. Among these, 282 (54%) received a transplant in first complete remission. At 3 years, posttransplant cumulative incidences of relapse, nonrelapse mortality, and relapse-free survival (RFS) were estimated at 19.5%, 15.5%, and 64.7%, respectively. Time-dependent analysis did not reveal a significant difference in RFS between SCT and no-SCT cohorts. However, SCT was associated with longer RFS in patients with postinduction minimal residual disease (MRD) ≥10(-3) (hazard ratio, 0.40) but not in good MRD responders. In B-cell precursor ALL, SCT also benefitted patients with focal IKZF1 gene deletion (hazard ratio, 0.42). This article shows that poor early MRD response, in contrast to conventional ALL risk factors, is an excellent tool to identify patients who may benefit from allogeneic SCT in the context of intensified adult ALL therapy. Trial GRAALL-2003 was registered at www.clinicaltrials.gov as #NCT00222027; GRAALL-2005 was registered as #NCT00327678.

    The association of neurofibromatosis 1 (NF1), juvenile xanthogranulomas (JXG), and juvenile myelomonocytic leukemia (JMML) has been previously reported. We describe herein this triad in a Caucasian male infant with a pathogenic mutation in the NF1 gene (neurofibromin). The clinical course from initial presentation to final diagnosis is detailed; the physical features and hematological characteristics are discussed. The patient underwent bone marrow transplantation and is currently in remission. Children with concurrent cutaneous café-au-lait and JXG lesions should be evaluated and monitored closely for the possible development of JMML. PMID:19785027

    Angiotensin-converting enzyme (ACE) converts angiotensin I to the vasoconstrictor angiotensin II and thereby plays an important role in blood pressure control. However, ACE is relatively non-specific in its substrate specificity and cleaves many other peptides. Recent analysis of mice overexpressing ACE in monocytes, macrophages, and other myelomonocytic cells shows that these animals have a marked increase in resistance to experimental melanoma and to infection by Listeria monocytogenes or methicillin-resistant Staphylococcus aureus (MRSA). Several other measures of immune responsiveness, including antibody production, are enhanced in these animals. These studies complement a variety of studies indicating an important role of ACE in the immune response. PMID:27018193

    Chronic myelomonocytic leukemia (CMML) is a clonal disorder sharing features of myelodysplastic syndromes and chronic myeloproliferative neoplasms. Although rare chromosomal aberrations and point mutations are reported in CMML, the molecular defects underlying CMML are largely unknown. ROS1 encodes a tyrosine kinase that is abnormally expressed and translocated in brain and lung cancers. In this study we show that ROS1 is abnormally activated in the CD34+ compartment of approximately 70% of CMML patients resulting in the activation of the Erk/Akt pathways through the Grb2/SOS complex thus revealing a central oncogenic role for ROS1 in CMML which might represent a molecular target.

    The purpose of this work was to assess the clinical and epidemiologic presentation features of adult acute diarrhea in a general hospital form Córdoba City. All the patients older than 14 years old who assisted to the Hospital Nacional de Clínicas Central Guard for acute diarrhea, during the periods: A (15-12-89 to 15-03-90), B (15-12-93 to 15-03-94) and C (15-12-94 to 15-03-95), were included. 594 patients were studied: 337 female (56.7%) and 257 male, 143 in the period A, 250 in B and 201 in C. The means +/- SD age was 34.6 +/- 13.3 and stool loose per day at admission 7.3 +/- 4.7. Eighty six percent of patients presented liquid consistent stool, 89.6% abdominal pain, 44.7% vomiting and 18.8% bloody stools. The rate of patients who consulted Central Guard referring acute diarrhea increased from period A (2.4%) to B (3.61%); p = 0.002 and decreased form B to C (2.85%); p = 0.01. The mean (+/- SD) days transcurred from the beginning of diarrhea episode till consultation was 3.5 +/- 2.7; 2.7 +/- 2.3 y 2.9 +/- 3.5 in the periods A, B and C respectively, statistically significant difference between A and B, p < 0.01. Thirty six percent, 21.1% and 23.1% of patients presented mucus with their stools in the periods A, B and C (p = 0.01), and high temperature 61.1%, 48.1% and 48.5% respectively (p = 0.04). Twenty seven percent of stools samples cultures became positive in the periods A, 17.6% in B and 11.5% in C, statistically significant difference between A and C; p = 0.008. The results show that in a general hospital from Córdoba City the adult acute diarrhea is a frequent cause of consult. In the last years there were modifications in its clinical an epidemiologic presentation features.

    Study Objective: To evaluate the association between self-reported sleep quality among older adults during inpatient post-acute rehabilitation and one-year survival. Design: Prospective, observational cohort study. Setting: Two inpatient post-acute rehabilitation sites (one community and one Veterans Administration). Participants: Older patients (aged ≥ 65 years, n = 245) admitted for inpatient post-acute rehabilitation. Interventions: None. Measurements and Results: Within one year of post-acute rehabilitation, 57 participants (23%) were deceased. Cox proportional hazards models showed that worse Pittsburgh Sleep Quality Index (PSQI) total scores during the post-acute care stay were associated with increased mortality risk when controlling for amount of rehabilitation therapy received, comorbidities, and cognitive functioning (Hazard ratio [95% CI] = 1.11 [1.02-1.20]). Actigraphically estimated sleep was unrelated to mortality risk. Conclusions: Poorer self-reported sleep quality, but not objectively estimated sleep parameters, during post-acute rehabilitation was associated with shorter survival among older adults. This suggests self-reported poor sleep may be an important and potentially modifiable risk factor for negative outcomes in these vulnerable older adults. Studies of interventions to improve sleep quality during inpatient rehabilitation should therefore be undertaken, and the long-term health benefits of improved sleep should be explored.

    Philadelphia chromosome (Ph)-like acute lymphoblastic leukemia (ALL) is a high-risk subtype of ALL in children. There are conflicting data on the incidence and prognosis of Ph-like ALL in adults. Patients with newly diagnosed B-cell ALL (B-ALL) who received frontline chemotherapy at MD Anderson Cancer Center underwent gene expression profiling of leukemic cells. Of 148 patients, 33.1% had Ph-like, 31.1% had Ph(+), and 35.8% had other B-ALL subtypes (B-other). Within the Ph-like ALL cohort, 61% had cytokine receptor-like factor 2 (CRLF2) overexpression. Patients with Ph-like ALL had significantly worse overall survival (OS), and event-free survival compared with B-other with a 5-year survival of 23% (vs 59% for B-other, P = .006). Sixty-eight percent of patients with Ph-like ALL were of Hispanic ethnicity. The following were associated with inferior OS on multivariable analysis: age (hazard ratio [HR], 3.299; P < .001), white blood cell count (HR, 1.910; P = .017), platelet count (HR, 7.437; P = .005), and Ph-like ALL (HR, 1.818; P = .03). Next-generation sequencing of the CRLF2(+) group identified mutations in the JAK-STAT and Ras pathway in 85% of patients, and 20% had a CRLF2 mutation. Within the CRLF2(+) group, JAK2 mutation was associated with inferior outcomes. Our findings show high frequency of Ph-like ALL in adults, an increased frequency of Ph-like ALL in adults of Hispanic ethnicity, significantly inferior outcomes of adult patients with Ph-like ALL, and significantly worse outcomes in the CRLF2(+) subset of Ph-like ALL. Novel strategies are needed to improve the outcome of these patients.

    Background Therapeutic protocols used in adult acute lymphoblastic leukemia (ALL) are widely variable, and glucocorticoids (GCs) are essential components in ALL treatment. Therefore, this study aimed to evaluate the distribution of prominent glucocorticoid receptor (GR) gene polymorphic variants among adult ALL patients. We also investigated the association between GR messenger ribonucleic acid (mRNA) isoform expressions and the response to chemotherapy. Methods Fifty-two newly diagnosed Philadelphia-negative adult ALL patients and 30 healthy control subjects were enrolled in this study. Genotyping was carried out using a polymerase chain reaction (PCR)-restriction fragment length polymorphism analysis. GR mRNA isoform expressions were assayed by quantitative real-time PCR. Results ALL patients in this study had a median age of 34 years (range, 18-75). GRα expression was associated with complete remission (P=0.03), while GRγ mRNA expression was significantly higher in GC resistant patients (P=0.032) and in non-responders (P=0.019). However, there were no significant associations with GC resistance. The BclI polymorphic variant of the GR gene was the most frequent in adult ALL patients and was not associated with the GC response. Both higher GRα expression and lower GRγ expression were associated with achievement of complete remission, while higher GRγ expression was associated with GC-resistance. Conclusion Our data suggest that the level of GR isoform expression may be useful in predicting GC response, achievement of complete remission, and better event-free survival in ALL patients. However, further evaluation with a larger cohort of patients is warranted. PMID:26770951

    Background: Acute abdominal pain is a common symptom of emergency patients. The severity was always evaluated based on physicians’ clinical experience. The aim of this study was to establish an early risk stratification method (ERSM) for addressing adults with acute abdominal pain, which would guide physicians to take appropriate and timely measures following the established health-care policies. Methods: In Cohort 1, the records of 490 patients with acute abdominal pain that developed within the past 72 h were enrolled in this study. Measurement data and numeration data were compared with analysis of variance and Chi-square test, respectively. Multiple regression analysis calculated odd ratio (OR) value. P and OR values showed the impacts of factors. ERSM was established by clinical experts and statistical experts according to Youden index. In Cohort 2, data from 305 patients with acute abdominal pain were enrolled to validate the accuracy of the ERSM. Then, ERSM was prospectively used in clinical practice. Results: The ERSM was established based on the scores of the patient's clinical characteristics: right lower abdominal pain + 3 × diffuse abdominal pain + 3 × cutting abdominal pain + 3 × pain frequency + 3 × pain duration + fever + 2 × vomiting + 5 × stop defecation + 3 × history of abdominal surgery + hypertension history + diabetes history + hyperlipidemia history + pulse + 2 × skin yellowing + 2 × sclera yellowing + 2 × double lung rale + 10 × unconsciousness + 2 × right lower abdominal tenderness + 5 × diffuse abdominal tenderness + 4 × peritoneal irritation + 4 × bowel sounds abnormal + 10 × suspicious diagnosis + white blood cell count + hematocrit + glucose + 2 × blood urea nitrogen + 3 × creatine + 4 × serum albumin + alanine aminotransferase + total bilirubin + 3 × conjugated bilirubin + amylase. When the score was <18, the patient did not need hospitalization. A score of ≥18 and <38 indicated that the patient should be under

    Background Tiaprofenic acid is a a non-steroidal anti-inflammatory drug (NSAID). It is widely available around the world, with indications for osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, periarticular disorders, and strains and sprains. This review sought to evaluate the efficacy and safety of oral tiaprofenic acid in acute postoperative pain, using clinical studies of patients with established pain, and with outcomes measured primarily over 6 hours using standard methods. This type of study has been used for many decades to establish that drugs have analgesic properties. Objectives To assess the efficacy of single dose oral tiaprofenic acid in acute postoperative pain, and any associated adverse events. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to June 2009. Selection criteria Randomised, double blind, placebo-controlled trials of single dose orally administered tiaprofenic acid in adults with moderate to severe acute postoperative pain. Data collection and analysis Two review authors independently assessed trial quality and extracted data. We planned to use area under the “pain relief versus time” curve to derive the proportion of participants with tiaprofenic acid experiencing at least 50% pain relief over 4 to 6 hours, using validated equations; to use number needed to treat to benefit (NNT); the proportion of participants using rescue analgesia over a specified time period; time to use of rescue analgesia; information on adverse events and withdrawals. Main results Not one of eleven studies identified by the searches and examined in detail studied oral tiaprofenic acid against placebo in patients with established postoperative pain and therefore no results are available. Authors’ conclusions In the absence of evidence of efficacy for oral tiaprofenic acid in acute postoperative pain, its use in this indication is not justified at present. Because trials clearly

    Cancer progresses with a change in the structure of the gene network in normal cells. We define a measure of organizational hierarchy in gene networks of affected cells in adult acute myeloid leukemia (AML) patients. With a retrospective cohort analysis based on the gene expression profiles of 116 AML patients, we find that the likelihood of future cancer relapse and the level of clinical risk are directly correlated with the level of organization in the cancer related gene network. We also explore the variation of the level of organization in the gene network with cancer progression. We find that this variation is non-monotonic, which implies the fitness landscape in the evolution of AML cancer cells is non-trivial. We further find that the hierarchy in gene expression at the time of diagnosis may be a useful biomarker in AML prognosis.

  13. Does aberrant membrane transport contribute to poor outcome in adult acute myeloid leukemia?

    2015-01-01

    Acute myeloid leukemia in adults is a highly heterogeneous disease. Gene expression profiling performed using unsupervised algorithms can be used to distinguish specific groups of patients within a large patient cohort. The identified gene expression signatures can offer insights into underlying physiological mechanisms of disease pathogenesis. Here, the analysis of several related gene expression clusters associated with poor outcome, worst overall survival and highest rates of resistant disease and obtained from the patients at the time of diagnosis or from previously untreated individuals is presented. Surprisingly, these gene clusters appear to be enriched for genes corresponding to proteins involved in transport across membranes (transporters, carriers and channels). Several ideas describing the possible relationship of membrane transport activity and leukemic cell biology, including the “Warburg effect,” the specific role of chloride ion transport, direct “import” of metabolic energy through uptake of creatine phosphate, and modification of the bone marrow niche microenvironment are discussed.

    Fifty-eight adult patients with acute leukemia were screened at the onset of the disease for hepatitis B antigen (HBSAg) in the serum, and during the course of the disease for the development of hepatitis B. One patient had a positive test for HBSAg by the radioimmunoassay technique only at the time leukemia was diagnosed; this patient had received transfusions some years before. In six patients icteric hepatitis B developed; five recovered completely and one died of leukemia during the course of hepatitis. All patients in whom hepatitis developed had received transfusions as a part of supportive therapy for leukemia. The hepatitis risk for patients who received transfusions of blood found to be negative for HBSAg by counterimmunoelectrophoresis was 0.26 percent per unit of blood administered. PMID:1054615

    We encountered 6 rare cases of acute-onset unilateral psychogenic hearing loss in adults. All were women in their 20s and 30s. Three cases had severe hearing impairment characterized by hearing loss at every frequency; 2 cases had profound hearing impairment, and 1 case had low-frequency hearing impairment. Of the 6 cases, 3 had a history of hearing loss, and 1 had a history of psychogenic visual disturbance. All 6 cases were initially diagnosed as having idiopathic sudden sensorineural hearing loss; all subsequently received steroid therapy. Three cases were not diagnosed as being psychogenic in origin until otoacoustic emissions and auditory brain responses were performed. Although the presence of distinctive clinical features (age, gender, and past history) is important for suspecting psychogenic hearing loss, objective audiological tests such as otoacoustic emissions are essential for diagnosing some cases. Compared to the existing reports of similar cases, our cases had a poorer prognosis (only 2 cases were cured).

    Background Blood cultures are obtained clinically to confirm site and source of acute infection as well as to guide effective antibiotic therapies. Patients with cystic fibrosis (CF) are at risk for blood stream infection (BSI) as identified from positive blood culture results. Methods A retrospective chart review was performed of 190 adult CF patients from January 1, 2001 through December 1, 2015. All positive blood culture results were identified as to clinical relevance and source of BSI. Results There were a total of 3,053 blood cultures. One hundred fifty-one positive blood cultures were considered pathogenic and clinically significant. Venous access device-related BSI was identified in 31 evaluable patients and 106 blood cultures. Nineteen patients and 45 positive blood cultures were attributable to organ-specific sources. Conclusion Two patterns of BSI were identified: 1) venous access device infections without causal mortality and 2) organ-specific site infections with associated 26% mortality. PMID:27829951

    We retrospectively evaluated the prognostic significance of polypharmacy and inappropriate medication use among 150 patients >60 years of age receiving induction chemotherapy for acute myelogenous leukemia (AML). After adjustment for age and comorbidity, increased number of medications at diagnosis (≥ 4 versus ≤ 1) was associated with increased 30-day mortality (OR=9.98, 95% CI=1.18-84.13), lower odds of complete remission status (OR=0.20, 95% CI=0.06-0.65), and higher overall mortality (HR=2.13, 95% CI=1.15-3.92). Inappropriate medication use (classified according to Beers criteria) was not significantly associated with clinical outcomes. Polypharmacy warrants further study as a modifiable marker of vulnerability among older adults with AML.

    Urinary tract infections (UTI) cause a great number of morbidity and mortality. These infections are serious complications in pregnancy, patients with diabetes, polycystic kidneys disease, sickle cell anaemia, kidney transplant and in patients with functional or structural anomalies of the urinary tract. The aim of this investigation was to determine a dominant causative agents of UTI and some of the clinical and laboratory characteristics of acute community-acquired UTI in adult hospitalised patients. We studied 200 adult patients with acute community-acquired UTI hospitalised in the Clinic for Infectious Diseases Tuzla from January 2006 to December 2007. The patients were divided into two groups: a group of patients with E. coli UTI (147) and a group of patients with non-E. coli UTI (53). In these two groups, the symptoms and signs of illness, blood test and urine analysis results were analysed. Our results have shown that the patients with E. coli UTI frequently had fever higher than 38,5 degrees C (p<0,0001), chills (p=0,0349), headache (p=0,0499), cloudy urine (p<0,0001), proteinuria (p=0,0011) and positive nitrite-test (p=0,0002). The patients with non-E. coli UTI frequently had fever lower than 38,5 degrees C (p<0,0001) and urine specific gravity <1015 (p=0,0012). There was no significant difference in blood test results between patients with E. coli and non-E. coli UTI. These clinical and laboratory findings can lead us to early etiological diagnosis of these UTI before urine culture detection of causative agents, which takes several days. Early etiological diagnosis of the E. coli and non-E. coli UTI is necessary for an urgent administration of appropriate empirical antibiotic treatment. This is very important in prevention of irreversible kidney damage, prolonged treatment, complications, as well as recidives and chronicity of the illness.

    The transition from wakefulness to sleep is associated with a pronounced decline in diuresis, a necessary physiological process that allows uninterrupted sleep. The aim of this study was to assess the effect of acute sleep deprivation (SD) on urine output and renal water, sodium, and solute handling in healthy young volunteers. Twenty young adults (10 male) were recruited for two 24-h studies under standardized dietary conditions. During one of the two admissions, subjects were deprived of sleep. Urine output, electrolyte excretions, and osmolar excretions were calculated. Activated renin, angiotensin II, aldosterone, arginine vasopressin, and atrial natriuretic peptide were measured in plasma, whereas prostaglandin E(2) and melatonin were measured in urine. SD markedly increased the diuresis and led to excess renal sodium excretion. The effect was more pronounced in men who shared significantly higher diuresis levels during SD compared with women. Renal water handling and arginine vasopressin levels remained unaltered during SD, but the circadian rhythm of the hormones of the renin-angiotensin-aldosterone system was significantly affected. Urinary melatonin and prostaglandin E(2) excretion levels were comparable between SD and baseline night. Hemodynamic changes were characterized by the attenuation of nocturnal blood pressure dipping and an increase in creatinine clearance. Acute deprivation of sleep induces natriuresis and osmotic diuresis, leading to excess nocturnal urine production, especially in men. Hemodynamic changes during SD may, through renal and hormonal processes, be responsible for these observations. Sleep architecture disturbances should be considered in clinical settings with nocturnal polyuria such as enuresis in children and nocturia in adults.

    Regular use of aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) has been hypothesized to be associated with reduced risk of hematologic cancer, although previous results have been inconsistent. The current study investigated the effects of aspirin or acetaminophen use on adult acute leukemia risk among 169 individuals with leukemia and 676 age and sex matched hospital controls with non-neoplastic conditions who completed a comprehensive epidemiologic questionnaire. Results indicate that regular aspirin use may be associated with a modest decrease in leukemia risk [adjusted odds ratio (aOR), 0.84; 95% confidence interval (CI), 0.59-1.21]. In contrast, ever using acetaminophen was associated with elevated leukemia risk (aOR, 1.53; 95% CI, 1.03-2.26). Results did not differ between men and women. Other studies have demonstrated that acetaminophen is associated with transient decreases in DNA repair, and lymphocytes may be particularly susceptible to DNA damage, suggesting a mechanism for the elevated acute leukemia risk observed among acetaminophen users.

    The aim of this study is to report ophthalmic findings of acute mercury poisoning in 48 adults referred to emergency department. Full ophthalmologic examination including the best corrected visual acuity, external eye examination, reaction to light, a slit-lamp examination, funduscopy, intraocular pressure measurements, and visual field (VF) and color vision (CV) tests were performed at the presentation and repeated after 6 months. The parametric values of VF test, the mean deviation (MD), and pattern standard deviation (PSD) were recorded in order to compare patients and the 30 healthy controls. The mean parameter of color confusion index in patients was found to be statistically different than controls (p < 0.01). The MD and PSD in patients were different from controls statistically significant (p < 0.01 and p < 0.01, respectively). There was no correlation between the ocular findings and the urine and blood mercury levels. Methyl mercury, held in the school laboratory for experimental purpose, may be a source of poisoning. In this case series, we showed that acute exposure to mercury had hazardous effect on the visual system, especially CV and VF. We propose that emphasizing the public education on the potential hazards of mercury is crucial for preventive community health.

    We report four cases of fatal mercury vapor inhalation, a rare occurrence. The mercury vapor was released at a private home, where one of the occupants was smelting silver from dental amalgam containing an unknown amount of mercury. Within 24 hours of the incident, all occupants began having shortness of breath necessitating hospital admission. The clinical courses are briefly detailed; however, all included rapid deterioration with respiratory failure. Chest roentgenograms in all four cases were consistent with adult respiratory distress syndrome. All patients were treated with dimercaprol, a mercury chelator, but all died, with survival varying from 9 to 23 days postexposure. Autopsies were performed on all four patients. The lungs in all cases were heavy, firm, and airless. Histologic examination revealed severe diffuse alveolar damage, with variable amounts of fibrosis, conforming with acute lung injury in various stages of organization. Additional postmortem findings included acute proximal renal tubular necrosis, vacuolar hepatoxicity, and a spectrum of central nervous system alterations including multifocal ischemic necrosis, gliosis, and vasculitis.

    Accidental radiation exposure and the threat of deliberate radiation exposure have been in the news and are a public health concern. Experience with acute radiation sickness has been gathered from atomic blast survivors of Hiroshima and Nagasaki and from civilian nuclear accidents as well as experience gained during the development of radiation therapy for cancer. This paper reviews the medical treatment reports relevant to acute radiation sickness among the survivors of atomic weapons at Hiroshima and Nagasaki, among the victims of Chernobyl, and the two cases described so far from the Fukushima Dai-Ichi disaster. The data supporting the use of hematopoietic stem cell transplantation and the new efforts to expand stem cell populations ex vivo for infusion to treat bone marrow failure are reviewed. Hematopoietic stem cells derived from bone marrow or blood have a broad ability to repair and replace radiation induced damaged blood and immune cell production and may promote blood vessel formation and tissue repair. Additionally, a constituent of bone marrow-derived, adult pluripotent stem cells, very small embryonic like stem cells, are highly resistant to ionizing radiation and appear capable of regenerating radiation damaged tissue including skin, gut and lung.

    This study consisted of a survey of 180 families who requested formaldehyde sampling of their homes through the local health or state health departments in Indiana in 1980-1985. At the time that the air sample was collected, the residents of the house were interviewed regarding the presence and severity of 22 acute health symptoms suspected to be associated with formaldehyde exposure. Surveyed individuals did not know the concentration of formaldehyde in their home at the time of the interview. For the purpose of this report, analysis was limited to the oldest (typically the only) adult woman in the household who was interviewed on the day that the air sample was taken (n = 163). The level of formaldehyde in the samples ranged from less than 0.010 ppm to 0.750 ppm. Comparisons of the formaldehyde concentrations with the health symptoms indicate that formaldehyde levels above 0.050 ppm did not increase the likelihood of the women to report the presence of any of the acute health symptoms studied. However, formaldehyde levels above 0.100 ppm significantly increased the likelihood of the women to report eye and sinus irritation, difficulty in breathing and sleeping, runny nose, and chest pain.

  6. Pharmacotherapy of Acute Bipolar Depression in Adults: An Evidence Based Approach

    PubMed Central

    2016-01-01

    In the majority of cases of bipolar disorder, manic episodes are usually brief and typically responsive to currently available psychopharmacological agents. In contrast, depressive manifestations are more prevalent and persistent, and can present as major depressive/mixed episodes or residual interepisode symptoms. The depressive phase is often associated with other neuropsychiatric conditions, such as anxiety spectrum disorders, substance use disorders, stressor-related disorders, and eating disorders. It is viewed as a systemic disease with associated ailments such as metabolic syndrome, diabetes mellitus, and cardiovascular disease. There is an increased rate of mortality not only from suicide, but also from concomitant physical illness. This scenario is made worse by the fact that depressive symptoms, which represent the main disease burden, are often refractory to existing psychotropic drugs. As such, there is a pressing need for novel agents that are efficacious in acute depressive exacerbations, and also have applicable value in preventing recurrent episodes. The rationale of the present review is to delineate the pharmacotherapy of the depressive phase of bipolar disorder with medications for which there is evidence in the form of observational, open-label, or double-blind randomized controlled studies. In the treatment of acute bipolar depression in adults, a comprehensive appraisal of the extant literature reveals that among mood stabilizers, the most robust proof of efficacy exists for divalproex sodium; while atypical antipsychotics, which include olanzapine, quetiapine, lurasidone, and cariprazine, are also effective, as demonstrated in controlled trials.

    2016-01-01

    Chronic myelomonocytic leukaemia (CMML) is a myelodysplastic/myeloproliferative neoplasm affecting the production and differentiation of the monocyte cell lineage. Cardiac surgery in the context of CMML poses challenges that are not routinely encountered. This is the first reported case in the literature of a patient with active CMML undergoing urgent on-pump coronary artery bypass grafting. A 68-year-old Caucasian man with a history of hypertension, hyperlipidaemia, hypothyroidism, and hypercholesterolaemia, who had been diagnosed by the haematologists with CMML a few months earlier but had remained untreated, underwent urgent surgical coronary revascularisation because of postinfarction angina following a non-ST elevation myocardial infarction associated with troponin I rise. The patient had fulminant postoperative myelomonocytic leukaemoid reaction, with a clinical picture of severe systemic inflammatory response syndrome and multiple organ dysfunction syndrome. This led to extensive vasodilation and heart failure that resulted in the death of the patient. Various authors have suggested different techniques and treatment options, each attempting to mitigate the effect of the postoperative inflammatory response. However, this is a high-risk endeavour with a myriad of inflammatory signals mobilised into action because of the surgical insult. Off-pump surgery or preoperative pharmacological attenuation of CMML activity might have dampened this response and resulted in a positive outcome for the patient. PMID:27990115

    Background Thrombotic microangiopathies (TMA) in adults such as thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS) are life-threatening disorders if untreated. Clinical presentation is highly variable and prognostic factors for clinical course and outcome are not well established. Methods We performed a retrospective observational study of 62 patients with TMA, 22 males and 40 females aged 16 to 76 years, treated with plasma exchange at one center to identify clinical risk factors for the development of renal insufficiency. Results On admission, 39 of 62 patients (63%) had acute renal failure (ARF) with 32 patients (52%) requiring dialysis treatment. High systolic arterial pressure (SAP, p = 0.009) or mean arterial pressure (MAP, p = 0.027) on admission was associated with acute renal failure. Patients with SAP>140 mmHg on admission had a sevenfold increased risk of severe kidney disease (OR 7.464, CI 2.097–26.565). MAP>100 mmHg indicated a fourfold increased risk for acute renal failure (OR 4.261, CI 1.400–12.972). High SAP, diastolic arterial pressure (DAP), and MAP on admission were also independent risk factors for persistent renal insufficiency with the strongest correlation for high MAP. Moreover, a high C-reactive protein (CRP) level on admission correlated with renal failure in the course of the disease (p = 0.003). At discharge, renal function in 11 of 39 patients (28%) had fully recovered, 14 patients (23%) remained on dialysis, and 14 patients (23%) had non-dialysis-dependent chronic kidney disease. Seven patients (11%) died. We identified an older age as risk factor for death. Conclusions High blood pressure as well as high CRP serum levels on admission are associated with renal insufficiency in TMA. High blood pressure on admission is also a strong predictor of sustained renal insufficiency. Thus, adult TMA patients with high blood pressure may require special attention to prevent persistent renal failure

    2004-01-01

    Since 75% of patients with high-risk acute leukemia do not have a human leukocyte antigen (HLA)-identical sibling, alternative sources for hematopoietic stem cell transplantation (HSCT) are matched unrelated donors (MUD), unrelated umbilical cord blood (UD-UCB) and one HLA haplotype mismatched family members (haploidentical). The chance of finding a suitable donor in the international voluntary donor registries is limited by frequency of the HLA phenotype and the time required to identify the right donor from a potential panel, to establish eligibility and to harvest the cells. In adult MUD recipients, event-free survival ranges up to 50% and refers only to patients who undergo transplant, without taking into account those who do not find a donor. Umbilical cord blood offers the advantages of easy procurement, the absence of risks to donors, the reduced risk of transmitting infections, immediate availability of cryopreserved samples and acceptance of mismatches at two of the six antigens. Although UD-UCB transplantation is a viable option for children, it is seldom considered for adults. The great divergency between body weight and the number of hematopoietic cells in a standard cord blood unit, particularly if associated with a two-antigen mismatch, increases the risk of graft failure and delays hematopoietic reconstitution. Work on full-haplotype mismatched transplants has been proceeding for over 20 years. Originally, outcome in leukemia patients was disappointing because of high incidence of severe graft-vs.-host disease in T-replete transplants and high rejection rates in T-cell-depleted transplants. The breakthrough came with the use of a megadose of T-cell-depleted progenitor cells after a high-intensity conditioning regimen. Treating end-stage patients inevitably confounded clinical outcome in the early pilot studies. Today, high-risk acute leukemia patients are treated at less advanced stages of disease, receive a reasonably well tolerated conditioning

    The manifestations and outcome of adult patients with acute leukemia (AL) were examined to study the characteristics of the rheumatological prodrome of AL and to find whether it is a marker of a distinct clinical and laboratory course and whether it has any prognostic implication. During a 10-year period, 8/139 (5.8%) of AL patients presented with rheumatic manifestations. The average duration of the arthritis syndrome preceding the diagnosis of AL was 3.25 months. The most common pattern of presentation was a reactive arthritis-like syndrome involving the large joints asymmetrically and associated with low back pain. Distinctive features suggesting a paraneoplastic arthritis were severe pain disproportionate to physical findings, a poor response to conventional antirheumatic treatment, and early significant osteopenia or lytic bone lesions. The epidemiological, clinical and laboratory characteristics of patients with or without rheumatic manifestations were comparable, except for fever on presentation, the presence of transient metabolic derangement following chemotherapy, and the initial average hemoglobin, hematocrit and serum uric acid values. Moreover, the initial outcome of the two groups was similar, as the early mortality rates were comparable (42.8% vs. 45% for patients with or without arthritis, respectively). In conclusion, rheumatic syndrome presentation of adult AL is uncommon, and apparently has no deleterious effects on initial prognosis. A timely diagnosis requires an increased awareness to distinctive features.

    Large concentrations of the beta-amino acid, taurine, can be found in many forebrain areas such as the basolateral amygdala, a portion of the limbic forebrain intimately associated with the regulation of fear/anxiety-like behaviors. In addition to its cytoprotective and osmoregulatory roles, taurine may also serve as an agonist at GABA(A)- and strychnine-sensitive glycine receptors. In this latter context, the present study demonstrates that application of taurine to acutely isolated neurons from the basolateral amygdala of adult rats causes significant alterations in resting membrane current, as measured by whole-cell patch clamp electrophysiology. Using standard pharmacological approaches, we find that currents gated by concentrations of taurine adult rats.

    In adult patients with acute lymphoblastic leukemia (ALL), Central Nervous System (CNS) involvement is associated with a very poor prognosis. The diagnostic assessment of this condition relies on the use of neuroradiology, conventional cytology (CC) and flow cytometry (FCM). Among these approaches, which is the gold standard it is still a matter of debate. Neuroradiology and CC have a limited sensitivity with a higher rate of false negative results. FCM demonstrated a superior sensitivity over CC, particularly when low levels of CNS infiltrating cells are present. Although prospective studies of a large series of patients are still awaited, a positive finding by FCM appears to anticipate an adverse outcome even if CC shows no infiltration. Current strategies for adult ALL CNS-directed prophylaxis or therapy involve systemic and intrathecal chemotherapy and radiation therapy. An early and frequent intrathecal injection of cytostatic combined with systemic chemotherapy is the most effective strategy to reduce the frequency of CNS involvement. In patients with CNS overt ALL, at diagnosis or upon relapse, allogeneic hematopoietic stem cell transplantation might be considered. This review discusses risk factors, diagnostic techniques for identification of CNS infiltration and modalities of prophylaxis and therapy to manage it. PMID:25408861

    Recent studies indicate that survivors of childhood acute lymphoblastic leukemia (ALL) are at increased risk of obesity and cardiovascular disease, conditions that healthy dietary patterns may help ameliorate or prevent. To evaluate the usual dietary intake of adult survivors of childhood ALL, food frequency questionnaire data were collected from 72 participants, and compared with the 2007 World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) Cancer Prevention recommendations, the Dietary Approaches to Stop Hypertension (DASH) diet, and the 2005 United States Department of Agriculture (USDA) Food Guide. Mean daily energy intake was consistent with estimated requirements; however, mean body mass index was 27.1 kg/m2 (overweight). Dietary index scores averaged fewer than half the possible number of points on all 3 scales, indicating poor adherence to recommended guidelines. No study participant reported complete adherence to any set of guidelines. Although half the participants met minimal daily goals for 5 servings of fruits and vegetables (WCRF/AICR recommendations) and adult survivors of childhood ALL is not concordant with dietary recommendations that may help reduce their risk of obesity, cardiovascular disease, or other treatment-related late effects.

    Acute bronchitis is a predominantly viral illness and, according to clinical practice guidelines, should not be treated with antibiotics. Despite clear guidelines, acute bronchitis continues to be the most common acute respiratory illness for which antibiotics are incorrectly prescribed. Although the national benchmark for antibiotic prescribing for adults with acute bronchitis is 0%, a preliminary record review before implementing the intervention at the project setting showed that 96% (N = 30) of adults with acute bronchitis in this setting were prescribed an antibiotic. This quality improvement project utilized a single-group, pre-post design. The setting for this project was a large urgent care network with numerous locations in central North Carolina. The purpose was to determine whether nurse practitioners and physician assistants, after participating in a multifaceted provider education session, would reduce inappropriate antibiotic prescribing for healthy adults with acute uncomplicated bronchitis. Twenty providers attended 1 of 4 training sessions offered in October and November 2015. The face-to-face interactive training sessions focused on factors associated with inappropriate antibiotic prescribing, current clinical practice guidelines, and patient communication skills. Retrospective medical record review of 217 pretraining and 335 posttraining encounters for acute bronchitis by 19 eligible participating providers demonstrated a 61.9% reduction in immediate antibiotic prescribing from 91.7% to 29.8%. Delayed prescribing, which accounted for a small percentage of the total prescriptions given, had a small but significant increase of 9.3% after training. Overall, this multifaceted, interactive provider training resulted in significant reductions in inappropriate prescriptions.

    Juvenile myelomonocytic leukemia is a clonal malignant disease affecting young children. Current cure rates, even with allogeneic hematopoietic stem cell transplantation, are no better than 50%–60%. Pre-clinical research on juvenile myelomonocytic leukemia is urgently needed for the identification of novel therapies but is hampered by the unavailability of culture systems. Here we report a xenotransplantation model that allows long-term in vivo propagation of primary juvenile myelomonocytic leukemia cells. Persistent engraftment of leukemic cells was achieved by intrahepatic injection of 1×106 cells into newborn Rag2−/−γc−/− mice or intravenous injection of 5×106 cells into 5-week old mice. Key characteristics of juvenile myelomonocytic leukemia were reproduced, including cachexia and clonal expansion of myelomonocytic progenitor cells that infiltrated bone marrow, spleen, liver and, notably, lung. Xenografted leukemia cells led to reduced survival of recipient mice. The stem cell character of juvenile myelomonocytic leukemia was confirmed by successful serial transplantation that resulted in leukemia cell propagation for more than one year. Independence of exogenous cytokines, low donor cell number and slowly progressing leukemia are advantages of the model, which will serve as an important tool to research the pathophysiology of juvenile myelomonocytic leukemia and test novel pharmaceutical strategies such as DNA methyltransferase inhibition.

  18. Whole adult organism transcriptional profiling of acute metal exposures in male Zebrafish

    PubMed Central

    2014-01-01

    Background A convergence of technological breakthroughs in the past decade has facilitated the development of rapid screening tools for biomarkers of toxicant exposure and effect. Platforms using the whole adult organism to evaluate the genome-wide response to toxicants are especially attractive. Recent work demonstrates the feasibility of this approach in vertebrates using the experimentally robust zebrafish model. In the present study, we evaluated gene expression changes in whole adult male zebrafish following an acute 24 hr high dose exposure to three metals with known human health risks. Male adult zebrafish were exposed to nickel chloride, cobalt chloride or sodium dichromate concentrations corresponding to their respective 96 hr LC20, LC40 and LC60. Histopathology was performed on a subset of metal-exposed zebrafish to phenotypically anchor transcriptional changes associated with each metal. Results Comparative analysis identified subsets of differentially expressed transcripts both overlapping and unique to each metal. Application of gene ontology (GO) and transcription factor (TF) enrichment algorithms revealed a number of key biological processes perturbed by metal poisonings and the master transcriptional regulators mediating gene expression changes. Metal poisoning differentially activated biological processes associated with ribosome biogenesis, proteosomal degradation, and p53 signaling cascades, while repressing oxygen-generating pathways associated with amino acid and lipid metabolism. Despite appreciable effects on gene regulation, nickel poisoning did not induce any morphological alterations in male zebrafish organs and tissues. Histopathological effects of cobalt remained confined to the olfactory system, while chromium targeted the gills, pharynx, and intestinal mucosa. A number of enriched transcription factors mediated the observed gene response to metal poisoning, including known targets such as p53, HIF1α, and the myc oncogene, and novel

    We aim to evaluate the incidence and clinical manifestations of sensorineural hearing loss (SNHL) in adult patients with acute otitis media (AOM). Seventy-five patients (age > 18 years; 83 ears) diagnosed with AOM between January 2008 and March 2011 at our clinic were enroled and retrospectively reviewed. We detected audiometrically confirmed SNHL during the course of AOM in eight patients. The clinical course, treatment, and audiometric final outcome of each case were reviewed. SNHL was associated with AOM in 8 out of 83 ears (9.3%). The mean age of patients was 57.5 years, and the mean follow-up period was 21.1 months (range 0.6-46.3 months). The most common symptom was tinnitus. Mean bone conduction hearing threshold was 39.5 dB in pure tone audiometry. All patients showed high-frequency HL, and three showed pan-frequency HL. All patients were treated with oral antibiotics at the initial visit. Seven ears were treated with a combination of oral steroids. Myringotomy was also performed. Seven of eight patients showed improvement; however, 8 kHz thresholds were not improved. This suggested that the inflammation spread through the round window. The mean duration of recovery was 18.6 days. SNHL associated with AOM in adult patients occurs during the early phases of the disease course. High-frequency hearing was commonly affected and was well treated with oral antibiotics, myringotomy, and steroid therapy. Audiometry can be helpful for treating adult patients with AOM. Active treatment, including myringotomy, should be performed during the early phase, if SNHL is suspected.

    With intensified pediatric-like therapy and genetic disease dissection, the field of adult acute lymphoblastic leukemia (ALL) has evolved recently. In this new context, we aimed to reassess the value of conventional risk factors with regard to new genetic alterations and early response to therapy, as assessed by immunoglobulin/T-cell receptor minimal residual disease (MRD) levels. The study was performed in 423 younger adults with Philadelphia chromosome-negative ALL in first remission (265 B-cell precursor [BCP] and 158 T-cell ALL), with cumulative incidence of relapse (CIR) as the primary end point. In addition to conventional risk factors, the most frequent currently available genetic alterations were included in the analysis. A higher specific hazard of relapse was independently associated with postinduction MRD level ≥10(-4) and unfavorable genetic characteristics (ie, MLL gene rearrangement or focal IKZF1 gene deletion in BCP-ALL and no NOTCH1/FBXW7 mutation and/or N/K-RAS mutation and/or PTEN gene alteration in T-cell ALL). These 2 factors allowed definition of a new risk classification that is strongly associated with higher CIR and shorter relapse-free and overall survival. These results indicate that genetic abnormalities are important predictors of outcome in adult ALL not fully recapitulated by early response to therapy. Patients included in this study were treated in the multicenter GRAALL-2003 and GRAALL-2005 trials. Both trials were registered at http://www.clinicaltrials.gov as #NCT00222027 and #NCT00327678, respectively.

    Neonatal rats have a high intestinal lactase activity, which declines around weaning. Yet, the effects of lactose-containing products are often studied in adult animals. This report is on the residual, post-weaning lactase activity and on the short- and long-term effects of lactose exposure in adult rats. Acutely, the postprandial plasma response to increasing doses of lactose was studied, and chronically, the effects of a 30% lactose diet fed from postnatal (PN) Day 15 onwards were evaluated. Intestinal lactase activity, as assessed both in vivo and in vitro, was compared between both test methods and diet groups (lactose vs. control). A 50%-75% decreased digestive capability towards lactose was observed from weaning into adulthood. Instillation of lactose in adult rats showed disproportionally low increases in plasma glucose levels and did not elicit an insulin response. However, gavages comprising maltodextrin gave rise to significant plasma glucose and insulin responses, indicative of a bias of the adult GI tract to digest glucose polymers. Despite the residual intestinal lactase activity shown, a 30% lactose diet was poorly digested by adult rats: the lactose diet rendered the animals less heavy and virtually devoid of body fat, whereas their cecum tripled in size, suggesting an increased bacterial fermentation. The observed acute and chronic effects of lactose exposure in adult rats cannot be explained by the residual intestinal lactase activity assessed.

    The aim of this study was to assess the impact of recurrent acute chest syndrome (ACS) episodes on the lung function of young adults with sickle cell disease (SCD). Our prospective study included 80 SCD adults [26 with recurrent acute chest syndrome (ACS)] and 80 ethnically matched controls aged between 18 and 28 years. Lung function (spirometry and lung volumes) was measured and the results were expressed as the percentage predicted for height. Bronchial hyperresponsiveness (BHR) was assessed by the response to either a bronchodilator or an exercise challenge. The adults with recurrent ACS (two or more ACS episodes) had lower median forced vital capacity (74 vs. 83%, p = 0.03), forced expiratory volume in 1 s (79 vs. 90%, p < 0.03), and total lung capacity (69 vs. 81%, p = 0.04) than SCD adults who had one or no ACS episodes. The greater the number of ACS episodes, the greater the reduction in lung function (p = 0.001). The adults with SCD had lower median forced vital capacity (81 vs. 106%), forced expiratory volume in 1 s (85 vs. 107%), and total lung capacity (80 vs. 87%) than the controls (p < 0.001). Similar numbers in each group had BHR (p = 0.2). The prevalence of restrictive ventilatory defect in the patients with SCD was almost double that of the controls (p = 0.004). Young adults with SCD have worse lung function than ethnically matched controls, particularly if they have suffered recurrent ACS episodes.

    This paper presents findings from a research study that investigated the education and training needs of qualified mental health nurses who work in acute adult mental health services in the UK. The study aimed to address a key knowledge 'gap' highlighted by recent Department of Health reports () that suggest that little is known regarding the education and training expectations, priorities and needs of mental health nurses who work in acute adult mental health services. This study aimed to identify (i) what type of post-registration education and training mental health nurses working in acute settings need; (ii) how the nurses want education and training to be delivered; and (iii) what qualifications and accreditation the nurses want to receive? The research consisted of two methods: focus groups and a questionnaire survey. This paper reports on the findings from the questionnaire survey. The results of the survey demonstrate that there is a real need for post-registration education and training for this group of nurses; to equip them with the relevant knowledge and skills to nurse people in the acute phase of their mental illness in acute inpatient settings.

    The use of gold nanoparticles is increasing in medicine; however, their toxic effects remain to be elucidated. Studies show that gold nanoparticles can cross the blood-brain barrier, as well as accumulate in the brain. Therefore, this study was undertaken to better understand the effects of gold nanoparticles on rat brains. DNA damage parameters were evaluated in the cerebral cortex of adult rats submitted to acute and chronic administration of gold nanoparticles of two different diameters: 10 and 30nm. During acute administration, adult rats received a single intraperitoneal injection of either gold nanoparticles or saline solution. During chronic administration, adult rats received a daily single injection for 28 days of the same gold nanoparticles or saline solution. Twenty-four hours after either single (acute) or last injection (chronic), the rats were euthanized by decapitation, their brains removed, and the cerebral cortices isolated for evaluation of DNA damage parameters. Our study showed that acute administration of gold nanoparticles in adult rats presented higher levels of damage frequency and damage index in their DNA compared to the control group. It was also observed that gold nanoparticles of 30nm presented higher levels of damage frequency and damage index in the DNA compared to the 10nm ones. When comparing the effects of chronic administration of gold nanoparticles of 10 and 30nm, we observed that occurred significant different index and frequency damage, comparing with control group. However, there is no difference between the 10 and 30nm groups in the levels of DNA damage for both parameters of the Comet assay. Results suggest that gold nanoparticles for both sizes cause DNA damage for chronic as well as acute treatments, although a higher damage was observed for the chronic one.

    Adults with sickle cell disease(SCD) are a growing population. Recent national estimates of outcomes in acute chest syndrome(ACS) among adults with SCD are lacking. We describe the incidence, outcomes and predictors of mortality in ACS in adults. We hypothesize that any need for mechanical ventilation is an independent predictor of mortality. Methods We performed a retrospective analysis of the Nationwide Inpatient Sample(2004–2010),the largest all payer inpatient database in United States, to estimate the incidence and outcomes of ACS needing mechanical ventilation(MV) and exchange transfusion(ET) in patients >21 years. The effects of MV and ET on outcomes including length of stay(LOS) and in-hospital mortality(IHM) were examined using multivariable linear and logistic regression models respectively. The effects of age, sex, race, type of sickle cell crisis, race, co-morbid burden, insurance status, type of admission, and hospital characteristics were adjusted in the regression models. Results Of the 24,699 hospitalizations, 4.6% needed MV(2.7% for <96 hours, 1.9% for ≥96 hours), 6% had ET, with a mean length of stay(LOS) of 7.8 days and an in-hospital mortality rate(IHM) of 1.6%. There was a gradual yearly increase in ACS hospitalizations that needed MV(2.6% in 2004 to 5.8% in 2010). Hb-SS disease was the phenotype in 84.3% of all hospitalizations. After adjusting for a multitude of patient and hospital related factors, patients who had MV for <96 hours(OR = 67.53,p<0.01) or those who had MV for ≥96 hours(OR = 8.73,p<0.01) were associated with a significantly higher odds for IHM when compared to their counterparts. Patients who had MV for ≥96 hours and those who had ET had a significantly longer LOS in-hospitals(p<0.001). Conclusion In this large cohort of hospitalized adults with SCD patients with ACS, the need for mechanical ventilation predicted higher mortality rates and increased hospital resource utilization.

    Background and Objective: Acute coronary syndrome (ACS) is one of the leading cause of morbidity and mortality worldwide. It is relatively uncommon in young adults as compared to the older population. Our objective was to assess the prevalence, demographic distribution, and risk factors for acute coronary syndrome (ACS) in patients less than 45 years of age admitted to a Malaysian tertiary care centre. Methods: This is a cross-sectional, retrospective, and single centre study with random sampling of the patients admitted for ACS to hospital from January 2005 to December 2013. Data were collected and analyzed. Patients less than 45 years of age were compared with patients more than 45 years of age. Result: A total of 628 patients were included in the study and with the prevalence of young ACS was 6.1% and mean age of 39±6 years. All the young ACS patients were diagnosed with unstable angina and non-ST elevation myocardial infarction (NSTEMI). Tobacco smoking and family history of coronary artery disease (CAD) were more frequent in young ACS. 59.5% of the young ACS patients were smokers, while 37.8% and 51.4% of them were found to suffer from diabetes mellitus and hypertension respectively. Tobacco smoking, diabetes mellitus, and hypertension had shown significant association with the onset of young ACS (p ≤ 0.05). Conclusion: Three leading risk factors (tobacco smoking, diabetes mellitus, and hypertension) had been shown to be significantly associated with the onset of young ACS. Thus, it is important to identify this cohort and implement aggressive measures in tackling the risk factors in order to prevent or halt the development of coronary artery disease. PMID:27648025

    The Wilms tumor 1 (WT1) gene has a complex role as a transcriptional regulator, acting as tumor suppressor or oncogene in different malignancies. The prognostic role of its overexpression has been well-studied in leukemias, especially acute myeloid leukemia (AML), but not in lymphomas. For the first time to our knowledge, we present a study demonstrating the correlation of WT1 expression and survival in various non-Hodgkin lymphomas. We also studied the prognostic implications of WT1 overexpression in adult acute lymphoblastic leukemia (ALL). In our sample of 53 patients--25 with diffuse large B-cell lymphoma (DLBCL), 8 with mantle cell lymphoma (MCL), 9 with peripheral T-cell lymphoma (PTCL), 2 with Burkitt's lymphoma, 2 with mucosa-associated lymphoid tissue (MALT) lymphoma, and 7 with B-cell ALL--, we measured WT1 mRNA from blood samples by quantitative RT-PCR, and divided the patients into subgroups based on the level of expression. Kaplan-Meier survival curves were drawn and compared using the logrank test. In the sample of DLBCL patients, the difference in overall and disease-free survival between WT1-positive and negative subgroups was significant (p = 0.0475 and p = 0.0004, respectively), and in a few observed cases, a sudden increase in WT1 expression signified a relapse soon followed by death. Disease-free survival curves in MCL and ALL were similarly suggestive of a potential role played by WT1. In PTCL, though WT1-positivity was detected in 4 out of 9 cases, it did not seem to affect survival. The few cases of MALT and Burkitt's lymphoma all proved to be WT1-negative.

    Second generation antipsychotic drugs are routinely used as treatment for psychotic disorders. Many of these compounds, including olanzapine, cause metabolic side-effects such as impaired glucose tolerance and insulin resistance. Individual antidiabetic drugs can help control elevated glucose levels in patients treated with antipsychotics, but the effects of combining antidiabetics, which routinely occurs with Type 2 diabetes mellitus patients, have never been studied. Presently, we compared the effects of the three different antidiabetics metformin (500mg/kg, p.o.), rosiglitazone (30mg/kg, p.o.) and glyburide (10mg/kg, p.o.) on metabolic dysregulation in adult female rats treated acutely with olanzapine. In addition, dual combinations of each of these antidiabetics were compared head-to-head against each other and the individual drugs. The animals received two daily treatments with antidiabetics and were then treated acutely with olanzapine (10mg/kg, i.p.). Fasting glucose and insulin levels were measured, followed by a 2h glucose tolerance test. Olanzapine caused a large and highly significant glucose intolerance compared to vehicle treated rats. Rosiglitazone decreased glucose levels non-significantly, while both metformin and glyburide significantly decreased glucose levels compared to olanzapine-only treated animals. For antidiabetic dual-drug combinations, the rosiglitazone-metformin group showed an unexpected increase in glucose levels compared to all of the single antidiabetic drugs. However, both the metformin-glyburide and rosiglitazone-glyburide groups showed significantly greater reductions in glucose levels following olanzapine than with single drug treatment alone for metformin or rosiglitazone, bringing glucose levels down to values equivalent to vehicle-only treated animals. These findings indicate that further study of antidiabetic dual-drug combinations in patients treated with antipsychotic drugs is warranted.

    Caffeine is a commonly used stimulant thought to have ergogenic properties. Most studies on the ergogenic effects of caffeine have been conducted in athletes. The purpose of this study was to test the hypothesis that caffeine reduces ratings of perceived exertion and increases liking of physical activity in sedentary adults. Participants completed treadmill walking at 60% to 70% of their maximal heart rate at baseline and for 6 subsequent visits, during which half of the participants were given caffeine (3 mg/kg) and half given placebo in a sports drink vehicle. To investigate the potential synergistic effects of acute and chronic caffeine on self-determined exercise duration, participants were rerandomized to either the same or different condition for the last visit, creating 4 chronic/acute treatment groups (placebo/placebo, placebo/caffeine, caffeine/placebo, caffeine/caffeine). Participants rated how much they liked the activity and perceived exertion at each visit. There was a main effect of time on liking of physical activity, with liking increasing over time and an interaction of sex and caffeine treatment on liking, with liking of activity increasing in female participants treated with caffeine, but not with placebo. There was no effect of caffeine on ratings of perceived exertion. Individuals who received caffeine on the final test day exercised for significantly longer than those who received placebo. These data suggest that repeated exposure to physical activity significantly increases liking of exercise and reduces ratings of perceived exertion and that caffeine does little to further modify these effects.

    Background and Purpose Acute disseminated encephalomyelitis (ADEM) is an inflammatory demyelinating disorder that predominantly affects children. Previous studies have mostly involved children in Western developed countries. Methods This study retrospectively reviewed the clinical profiles of ADEM in adult Chinese patients. Results ADEM occurred during summer and autumn in about two-thirds of the 42 included patients. Prior infection was found in five patients and no preimmunization was recorded. The most frequent clinical presentations were alterations in consciousness (79%) and behavior changes (69%), followed by motor deficits (64%) and fever (50%). About one-quarter (26%) of the patients showed positive results for oligoclonal bands, and about half of them exhibited increases in the IgG index and 24-hour IgG synthesis rate. Magnetic resonance imaging showed white- and gray-matter lesions in 83% and 23% of the patients, respectively. Steroids were the main treatment, and full recovery occurred in 62% of the patients, with residual focal neurological deficits recorded in a few patients. After a mean follow-up period of 3.4 years, two patients exhibited recurrence and one patient exhibited a multiphasic course. One patient was diagnosed with multiple sclerosis (MS). Conclusions With the exception of the seasonal distribution pattern and prior vaccine rate, the clinical profiles of ADEM in adult Chinese patients are similar to those in pediatric populations. No specific markers are available for distinguishing ADEM from MS at the initial presentation. Careful clinical evaluations, cerebrospinal fluid measurements, and neuroradiological examinations with long-term follow-up will aid the correct diagnosis of ADEM. PMID:27449911

    Ca2+ currents in acutely isolated, adult rat neostriatal neurons were studied with whole-cell voltage-clamp techniques. In the vast majority of neurons (approximately 90%, n > 250), currents were exclusively of the high-voltage-activated (HVA) type. HVA currents activated near -40 mV and reached their maximum amplitude near 0 mV. Quasi-steady-state inactivation curves in many neurons were well fitted only with a sum of Boltzmann functions, suggesting that the HVA currents were heterogeneous. Although the block of whole-cell current by Cd2+ was well fitted with a single isotherm having an IC50 of near 1 microM, experiments with organic channel antagonists suggested that at least four types of HVA channels were expressed by most cells. On average, the L-channel antagonist nifedipine (5-10 microM) blocked 31 +/- 10% of the whole-cell current (n = 20), the N-channel antagonist omega-conotoxin GVIA (omega-CgTx) (2-5 microM) blocked 27 +/- 11% (n = 20), and the P-channel antagonist omega-agatoxin IVA (100-500 nM) blocked 21 +/- 10% (n = 18). In many neurons, the block by omega-CgTx was partially or completely reversible. In cells tested with a combination of these antagonists, 34 +/- 17% of the peak Ca2+ current remained unblocked (n = 13). Single-cell expression profiling of medium-sized neurons revealed the presence of rbA and rbB Ca2+ channel alpha 1 subunit mRNAs but low or undetectable levels of rbC mRNA (n = 12). These findings suggest that although adult neostriatal projection neurons do not express significant levels of LVA Ca2+ current, they do express a pharmacologically and structurally heterogeneous population of HVA currents.

    OBJECTIVES To test the feasibility and utility of a bedside geriatric assessment (GA) to detect impairment in multiple geriatric domains in older adults initiating chemotherapy for acute myelogenous leukemia (AML). DESIGN Prospective observational cohort study. SETTING Single academic institution. PARTICIPANTS Individuals aged 60 and older with newly diagnosed AML and planned chemotherapy. MEASUREMENTS Bedside GA was performed during inpatient exmination for AML. GA measures included the modified Mini-Mental State Examination; Center for Epidemiologic Studies Depression Scale; Distress Thermometer, Pepper Assessment Tool for Disability (includes self- reported activities of daily living (ADLs), instrumental ADLs, and mobility questions); Short Physical Performance Battery (includes timed 4-m walk, chair stands, standing balance); grip strength, and Hematopoietic Cell Transplantation Comorbidity Index. RESULTS Of 54 participants (mean age 70.8 ± 6.4) eligible for this analysis, 92.6% completed the entire GA battery (mean time 44.0 ± 14 minutes). The following impairments were detected: cognitive impairment, 31.5%; depression, 38.9%; distress, 53.7%; impairment in ADLs, 48.2%; impaired physical performance, 53.7%; and comorbidity, 46.3%. Most were impaired in one (92.6%) or more (63%) functional domains. For the 38 participants rated as having good performance status according to standard oncologic assessment (Eastern Cooperative Oncology Performance Scale score ≤1), impairments in individual GA measures ranged from 23.7% to 50%. Significant variability in cognitive, emotional, and physical status was detected even after stratification according to tumor biology (cytogenetic risk group classification). CONCLUSION Inpatient GA was feasible and added new information to standard oncology assessment, which may be important for stratifying therapeutic risk in older adults with AML. PMID:22091497

    The cytidine analogues azacytidine and 5-aza-2'-deoxycytidine (decitabine) are commonly used to treat myelodysplastic syndromes, with or without a myeloproliferative component. It remains unclear whether the response to these hypomethylating agents results from a cytotoxic or an epigenetic effect. In this study, we address this question in chronic myelomonocytic leukaemia. We describe a comprehensive analysis of the mutational landscape of these tumours, combining whole-exome and whole-genome sequencing. We identify an average of 14±5 somatic mutations in coding sequences of sorted monocyte DNA and the signatures of three mutational processes. Serial sequencing demonstrates that the response to hypomethylating agents is associated with changes in DNA methylation and gene expression, without any decrease in the mutation allele burden, nor prevention of new genetic alteration occurence. Our findings indicate that cytosine analogues restore a balanced haematopoiesis without decreasing the size of the mutated clone, arguing for a predominantly epigenetic effect. PMID:26908133

    Recently, germline mutations of NRAS have been shown to be associated with Noonan syndrome (NS), a relatively common developmental disorder characterized by short stature, congenital heart disease, and distinctive facial features. We report on the mutational analysis of NRAS in a cohort of 125 French patients with NS and no known mutation for PTPN11, KRAS, SOS1, MEK1, MEK2, RAF1, BRAF, and SHOC2. The c.179G>A (p.G60E) mutation was identified in two patients with typical NS, confirming that NRAS germline mutations are a rare cause of this syndrome. We also screened our cohort of 95 patients with juvenile myelomonocytic leukemia (JMML). Among 17 patients with NRAS-mutated JMML, none had clinical features suggestive of NS. None of the 11 JMML patients for which germline DNA was available had a constitutional NRAS mutation.

    Juvenile myelomonocytic leukemia (JMML) is an aggressive myeloproliferative neoplasm of childhood associated with a poor prognosis. Recently, massively parallel sequencing has identified recurrent mutations in the SKI domain of SETBP1 in a variety of myeloid disorders. These lesions were detected in nearly 10% of patients with JMML and have been characterized as secondary events. We hypothesized that rare subclones with SETBP1 mutations are present at diagnosis in a large portion of patients who relapse, but are below the limits of detection for conventional deep sequencing platforms. Using droplet digital polymerase chain reaction, we identified SETBP1 mutations in 17/56 (30%) of patients who were treated in the Children’s Oncology Group sponsored clinical trial, AAML0122. Five-year event-free survival in patients with SETBP1 mutations was 18% ± 9% compared with 51% ± 8% for those without mutations (P = .006). PMID:25395418

    In the cure of cancer, a major cause of today's mortality, chemotherapy is the most common treatment, though serious frequent challenges are encountered by current anticancer drugs. We discovered that few-layer graphene (FLG) dispersions have a specific killer action on monocytes, showing neither toxic nor activation effects on other immune cells. We confirmed the therapeutic application of graphene on an aggressive type of cancer that is myelomonocytic leukemia, where the monocytes are in their malignant form. We demonstrated that graphene has the unique ability to target and boost specifically the necrosis of monocytic cancer cells. Moreover, the comparison between FLG and a common chemotherapeutic drug, etoposide, confirmed the higher specificity and toxicity of FLG. Since current chemotherapy treatments of leukemia still cause serious problems, these findings open the way to new and safer therapeutic approaches.

    A 65-year-old woman with chronic myelomonocytic leukemia was shown to have trisomy 6 and multiple double minute chromosomes. The patient had no history of prior exposure to any mutagenic or carcinogenic agents. To our knowledge, this is the first report for presence of only these two aberrations. The expression of several oncoproteins and onco-related proteins was detected immunohistochemically in bone marrow cells. Among them, only the bcl-2 oncoprotein was positively stained in 100% of myeloblasts. Although the c-myc oncogene is frequently reported to be overexpressed in myeloid disorders with double minutes and associated with chemotherapy resistance and disease aggressiveness, in our case, the c-myc oncoprotein was not positively expressed. The patient received chemotherapy and complete hematological remission was successfully achieved.

    In industrialized countries respiratory tract infections are one of the most common reasons for medical consultations. It is assumed that almost one third of these infections affect the lower respiratory tract (LRTI), e. g. acute bronchitis, acute exacerbation of chronic obstructive pulmonary disease (COPD), community- or hospital-acquired pneumonia and influenza. Due to a lack of sufficient and valid investigations on the epidemiology of respiratory viruses, their impact on the pathogenesis of LRTI has probably been underestimated for a long time. Therefore, there might have been many cases of needless antibiotic treatment, particularly in cases of acute bronchitis or acute exacerbations of COPD, because of an assumed bacteriological aetiology. Following the introduction of diagnostic procedures with increased sensitivity, such as polymerase chain reaction, it is possible to reliably detect respiratory viruses and to illuminate their role in the pathogenesis of LRTI of the adult. We have reviewed the current literature to elucidate the role of viruses in the pathogenesis of LRTI. The first part of this series described frequent viral pathogens, pathogenesis of viral LRTI, and diagnostic procedures. In this 2 (nd) part the aetiological role of viruses in the most frequent forms of LRTI will be highlighted, and the third and last part will provide an overview of therapeutic and preventive options.

    In some patients, acute respiratory distress syndrome (ARDS) leads to life-threatening refractory hypoxemia developing. Physicians may consider hypoxemic rescue therapies in an attempt to improve oxygenation in these patients while on conventional mechanical ventilation support. Use of inhaled nitric oxide (iNO) in ARDS is one of the most widely-studied pharmacological interventions over the past two decades. Its efficacy was examined in several randomized clinical trials and has undergone meta-analyses. Although iNO treatment was associated with improved oxygenation, researchers unfortunately never demonstrated a concomitant decrease in mortality or any improved outcome. Hence the current evidence suggests that iNO should not be routinely used in patients with ARDS however may be considered as adjunct therapy to tentatively improve oxygenation while other therapies are being considered in patients with severely hypoxemic ARDS.This review focuses on the therapeutic use of iNO in adult ARDS patients. We set out some recommendations for its use as rescue therapy against refractory hypoxemia.

    In animals, physical activity has been shown to induce functional and structural changes especially in the hippocampus and to improve memory, probably by upregulating the release of neurotrophic factors. In humans, results on the effect of acute exercise on memory are inconsistent so far. Therefore, the aim of the present study was to assess the effects of a single bout of physical exercise on memory consolidation and the underlying neuroendocrinological mechanisms in young adults. Participants encoded a list of German-Polish vocabulary before exercising for 30 minutes with either high intensity or low intensity or before a relaxing phase. Retention of the vocabulary was assessed 20 minutes after the intervention as well as 24 hours later. Serum BDNF and salivary cortisol were measured at baseline, after learning, and after the intervention. The high-intensity exercise group showed an increase in BDNF and cortisol after exercising compared to baseline. Exercise after learning did not enhance the absolute number of recalled words. Participants of the high-intensity exercise group, however, forgot less vocabulary than the relaxing group 24 hours after learning. There was no robust relationship between memory scores and the increase in BDNF and cortisol, respectively, suggesting that further parameters have to be taken into account to explain the effects of exercise on memory in humans.

    PR (PRDI-BF1 and RIZ) domain proteins (PRDM) are a subfamily of the kruppel-like zinc finger gene products that modulate cellular processes such as differentiation, cell growth and apoptosis. PRDM5 is a recently identified family member that functions as a transcriptional repressor and behaves as a putative tumor suppressor in different types of cancer. However, the expression and function of PRDM5 in spinal cord injury (SCI) are still unknown. In the present study, we have performed an acute SCI model in adult rats and investigated the dynamic changes of PRDM5 expression in the spinal cord. We found that PRDM5 protein levels gradually increased, reaching a peak at day 5 and then gradually declined to a normal level at day 14 after SCI with Western blot analysis. Double immunofluorescence staining showed that PRDM5 immunoreactivity was found in neurons, astrocytes and microglia. However, the expression of PRDM5 was increased predominantly in neurons. Additionally, colocalization of PRDM5/active caspase-3 was been respectively detected in neurons. In vitro, we found that depletion of PRDM5 by short interfering RNA, obviously decreases neuronal apoptosis. In summary, this is the first description of PRDM5 expression in SCI. Our results suggested that PRDM5 might play crucial roles in CNS pathophysiology after SCI and this research will provide new drug targets for clinical treatment of SCI.

    We compared outcomes from a single-arm study of blinatumomab in adult patients with B-precursor Ph-negative relapsed/refractory acute lymphoblastic leukemia (R/R ALL) with a historical data set from Europe and the United States. Estimates of complete remission (CR) and overall survival (OS) were weighted by the frequency distribution of prognostic factors in the blinatumomab trial. Outcomes were also compared between the trial and historical data using propensity score methods. The historical cohort included 694 patients with CR data and 1112 patients with OS data compared with 189 patients with CR and survival data in the blinatumomab trial. The weighted analysis revealed a CR rate of 24% (95% CI: 20-27%) and a median OS of 3.3 months (95% CI: 2.8-3.6) in the historical cohort compared with a CR/CRh rate of 43% (95% CI: 36-50%) and a median OS of 6.1 months (95% CI: 4.2-7.5) in the blinatumomab trial. Propensity score analysis estimated increased odds of CR/CRh (OR=2.68, 95% CI: 1.67-4.31) and improved OS (HR=0.536, 95% CI: 0.394-0.730) with blinatumomab. The analysis demonstrates the application of different study designs and statistical methods to compare novel therapies for R/R ALL with historical data.

    Our understanding of the genetic basis of childhood acute lymphoblastic leukemia (ALL) has been greatly advanced by genomic profiling and sequencing studies. These efforts have characterized the genetic basis of recently described and poorly understood subtypes of ALL, including early T-cell precursor ALL, Philadelphia chromosome-like (Ph-like) ALL, and ALL with intrachromosomal amplification of chromosome 21, and have identified several rational therapeutic targets in high-risk ALL, notably ABL1-class and JAK-STAT inhibitors in Ph-like ALL. Deep sequencing studies are also refining our understanding of the genetic basis of clonal heterogeneity and relapse. These studies have elucidated the nature of clonal evolution during disease progression and identified genetic changes that confer resistance to specific therapeutic agents, including CREBBP and NT5C2. Genomic profiling has also identified common and rare inherited genetic variants that influence the risk of developing leukemia. These efforts are now being extended to ALL in adolescents and adults with the goal of fully defining the genetic landscape of ALL to further improve treatment outcomes in high-risk populations.

    This was a cross-sectional study within Brazil's Project for the Expansion and Consolidation of Family Health, 2005, with the objective of universal and free access to the medication prescribed in the last medical appointment for acute health problems and to estimate the degree to which access may have improved with inclusion of the medicines in prevailing policies and programs. The sample included 4,060 adults living in the area of primary health care units in 41 municipalities in South and Northeast Brazil. Access was greater in the South (83.2%) than in the Northeast (71%), and free access was similar (37%), with a greater share by the Family Health Program (FHP) when compared to the traditional model, especially in the Northeast. Some 60% of prescribed medicines and 50% of those on the National List of Essential Medicines (RENAME) were paid for. No variation was observed in the proportion of medicines present on the prevailing RENAME list and access. However, 40% of the medicines that were paid for can currently be obtained through the Popular Pharmacy Program. The latter program appears to emerge as a new way to guarantee access to medicines prescribed in the health system.

    We used next-generation sequencing (NGS) of the immunoglobulin genes to evaluate residual disease in 153 specimens from 32 patients with adult B cell acute lymphoblastic leukemia enrolled in a single multicenter study. The sequencing results were compared with multiparameter flow cytometry (MFC) data in 66 specimens (25 patients) analyzed by both methods. There was a strong concordance (82%) between the methods in the qualitative determination of the presence of disease. However, in 17% of cases, leukemia was detected by sequencing but not by MFC. In 54 bone marrow (BM) and peripheral blood (PB) paired specimens, the burden of leukemia detected by NGS was lower in PB than in BM, although it was still detectable in 68% of the 28 paired specimens with positive BM. Lastly, patients without disease detected by NGS or MFC had a 5-year relapse free survival of > 80%. The results suggest that residual disease detection by immunoglobulin gene sequencing is an extremely sensitive technique and may identify patients that might benefit from transplantation. Moreover, the increased sensitivity of the method may allow frequent peripheral blood testing to supplement marrow sampling to measure disease response.

    We investigated the predictive value of geriatric assessment (GA) on overall survival (OS) for older adults with acute myelogenous leukemia (AML). Consecutive patients ≥ 60 years with newly diagnosed AML and planned intensive chemotherapy were enrolled at a single institution. Pretreatment GA included evaluation of cognition, depression, distress, physical function (PF) (self-reported and objectively measured), and comorbidity. Objective PF was assessed using the Short Physical Performance Battery (SPPB, timed 4-m walk, chair stands, standing balance) and grip strength. Cox proportional hazards models were fit for each GA measure as a predictor of OS. Among 74 patients, the mean age was 70 years, and 78.4% had an Eastern Cooperative Oncology Group (ECOG) score ≤ 1. OS was significantly shorter for participants who screened positive for impairment in cognition and objectively measured PF. Adjusting for age, gender, ECOG score, cytogenetic risk group, myelodysplastic syndrome, and hemoglobin, impaired cognition (Modified Mini-Mental State Exam < 77) and impaired objective PF (SPPB < 9) were associated with worse OS. GA methods, with a focus on cognitive and PF, improve risk stratification and may inform interventions to improve outcomes for older AML patients.

    2012-01-01

    With the goal of providing guidance on the provision of optimal intensive care to adult patients with acute liver failure (ALF), this paper defines ALF and describes a protocol for appropriately diagnosing this relatively rare clinical entity and ascertaining its etiology, where possible. This paper also identifies the few known therapies that may be effective for specific causes of ALF and provides a comprehensive approach for anticipating, identifying, and managing complications. Finally, one of the more important aspects of care for patients with ALF is the determination of prognosis and, specifically, the need for liver transplantation. Prognostic tools are provided to help guide the clinician in this critical decision process. Management of patients with ALF is complex and challenging, even in centers where staff members have high levels of expertise and substantial experience. This evidence-based protocol may, therefore, assist in the delivery of optimal care to this critically ill patient population and may substantially increase the likelihood of positive outcomes.

    The idea behind this thesis is to present how ARS and especially acute maxillary sinusitis in adults is diagnosed and treated in general practice. The study extends over many years, beginning with the first survey in 1991. Based on doctors' answers, we then investigated the diagnostic values ​​of the symptoms, signs and examinations which the doctors reported using. All patients over 18 years suspected of acute maxillary sinusitis were included consecutively and only once and, after a clinical examination with the GP, they were offered the opportunity to enter into the prospective study referred to acute CT scan and by changes in the CT, immediately referred to sinus puncture. Both examinations were conducted at Aalborg Hospital. The disease was found most frequently in younger and 2/3 were women. The reason for this gender difference is unknown. We have assessed the diagnostic values of the symptoms, objective findings and investigations ​​using 3 different reference standards: sinus puncture, microbiological diagnosis and CT scan described in three articles. In all examinations, it appeared that the usual signs and symptoms of acute maxillary sinusitis occur almost equally often and with a few exceptions in patients, with and without pus in the sinus cavities. Pain in the sinus cavities occurring in 95% of patients, and only elevated levels of CRP and ESR are significantly and independently associated with pus in the sinus cavities. This finding is surprising, because they are two nonspecific markers. CRP tested by near-patient testing has, within the investigations period, been introduced in general practice, and from 1999 the doctors also get reimbursed for performing the test. We have on this background originally defined a clinical criterion with pain over the sinuses accompanied by elevated values ​​of CRP and/or ESR giving a sensitivity of 0.82, specificity 0.57, ppv 0.68 and npv 0.74. But looking at the ROC curve we suggest that a more clinical

    Chronic myelomonocytic leukemia (CMML) is a myelodysplastic syndrome characterized by abnormal clonal myeloid proliferation, and by progression to acute myelogenous leukemia (AML). A recently recognized subgroup of CMML has a t(5;12) (q33;p13) balanced translocation. Fluorescence in situ hybridization (FISH) localized the translocation breakpoint near the CSF1 receptor (CSF1R) locus on chromosome 5q. Pulsed-field gel electrophoresis confirmed rearrangements near CSF1R, but involvement of CSF1R itself was excluded. Southern blotting showed a rearrangement within the closely linked PDGF receptor {beta} (PDGFR{beta}) gene. Ribonuclease protection assays localized the translocation breakpoint to nucleotide 1766 in PDGFR{beta} RNA. Anchored PCR was used to identify the chromosome 12 fusion partner, a novel ets-like protein, tel. Tel contains a highly conserved carboxy terminal ets-like DNA-binding domain, and an amino terminal domain with a predicted helix-loop-helix (HLH) secondary structure. The consequence of the t(5;12) translocation is fusion of the tel HLH domain to the PDGFR{beta} transmembrane and tyrosine kinase domains. The tel HLH domain may contribute a dimerization motif which serves to constitutively activate PDGFR{beta} tyrosine kinase activity. The tel-PDGFR{beta} fusion demonstrates the oncogenic potential of PDGFR{beta}, and may provide a paradigm for early events in the pathogenesis of AML.

    The treatment of patients with chronic myelomonocytic leukemia (CMML) with transplant has not been optimized. We retrospectively reviewed the data for 83 consecutive patients with CMML (47 with CMML-1/2 and 36 with CMML progressed to acute myeloid leukemia) who received an allogeneic stem cell transplant (allo-SCT) at our institution between April 1991 and December 2013 to identify factors associated with improved survival and determine whether treatment with hypomethylating agents before transplant improves progression-free survival (PFS). The median age of the cohort was 57 years. Seventy-eight patients received induction treatment before transplant, with 37 receiving hypomethylating agents and 41 receiving cytotoxic chemotherapy. Patients treated with a hypomethylating agent had a significantly lower cumulative incidence of relapse at 3 years post-transplant (22%) than those treated with other agents (35%; P = .03), whereas treatment-related mortality at 1 year post-transplant did not significantly differ between the groups (27% and 30%, respectively; P = .84). The lower relapse rate resulted in a significantly higher 3-year PFS rate in patients treated with a hypomethylating agent (43%) than in those treated with other agents (27%; P = .04). Our data support the use of hypomethylating agents before allo-SCT for patients with CMML to achieve morphologic remission and improve PFS of these patients. Future studies are needed to confirm these findings.

    SUMMARY Background Umbilical cord blood (UCB) is increasingly considered as an alternative to peripheral blood progenitor cells (PBPC) or bone marrow (BM), especially when a HLA-matched adult unrelated donor is not available. Methods In order to establish the appropriateness of current graft selection practices, we retrospectively compared leukemia-free survival and other outcomes for each graft source in patients aged >16 years transplanted for acute leukemia using Cox regression. Data were available on 1525 patients transplanted between 2002 and 2006 using UCB (n=165), PBPC (n=888) and BM (n=472). UCB units were matched at HLA-A and B at antigen level and DRB1 at allele level (n=10) or mismatched at one (n=40) or two antigens (n=115). PBPC and BM grafts from unrelated adult donors were matched for allele-level HLA-A, B, C and DRB1 (n=632; n=332) or mismatched at one locus (n=256; n=140). Findings Leukemia-free survival after UCB transplantation was comparable to that observed after 8/8 and 7/8 allele-matched PBPC or BM transplantation. Transplant-related mortality, however, was higher after UCB transplantation compared to 8/8 allele-matched PBPC (HR 1.62, p<0.01) or BM (HR 1.69, p<0.01). Grades 2–4 acute and chronic graft-versus-host disease were lower in UCB recipients compared to allele-matched PBPC (HR 0.57, p<0.01 and HR 0.38, p<0.01, respectively), while chronic and not acute graft-versus-host disease was lower after UCB compared to allele-matched BM transplantation (HR 0.63, p=0.01). Interpretation Together, these data support the use of UCB for adults with acute leukemia when an HLA-matched unrelated adult donor is lacking and when transplant is urgently needed. PMID:20558104

    Mental health nurses work with acutely unwell patients, and the busy setting is characterised by unpredictable events. This paper is a report of a review conducted to identify, analyse and synthesize research in adult acute inpatient mental health units, which focused on nurse-patient interaction. Several electronic databases were searched using relevant keywords to identify studies published from 1999-present. Qualitative studies published in English were included if they specifically investigated nurse-patient interaction in acute inpatient care in adult settings. Eighteen studies were included (23 papers). Findings were grouped into the following six categories: 1) sophisticated communication; 2) subtle discriminations; 3) managing security parameters; 4) ordinary communication; 5) reliance on colleagues; and 6) personal characteristics. These studies of acute inpatient mental health units reveal that nurse communication involves interpersonal approaches and modalities that exemplify highly developed communication and personal skills designed specifically for this challenging setting. Further quality research should focus on the conditions that enable the development of therapeutic interactional skills and the relationship of these skills to the nuanced context in which they are practiced.

    Objectives To determine whether over the counter cough medicines are effective for acute cough in adults. Design Systematic review of randomised controlled trials. Data sources Search of the Cochrane Acute Respiratory Infections Group specialised register, Cochrane Controlled Trials Register, Medline, Embase, and the UK Department of Health National Research Register in all languages. Included studies All randomised controlled trials that compared oral over the counter cough preparations with placebo in adults with acute cough due to upper respiratory tract infection in ambulatory settings and that had cough symptoms as an outcome. Results 15 trials involving 2166 participants met all the inclusion criteria. Antihistamines seemed to be no better than placebo. There was conflicting evidence on the effectiveness of antitussives, expectorants, antihistamine-decongestant combinations, and other drug combinations compared with placebo. Conclusion Over the counter cough medicines for acute cough cannot be recommended because there is no good evidence for their effectiveness. Even when trials had significant results, the effect sizes were small and of doubtful clinical relevance. Because of the small number of trials in each category, the results have to be interpreted cautiously. What is already know on this topicThe NHS encourages self treatment of acute self limiting illnessesOver the counter cough medicines are commonly used as first line treatment for acute coughWhat this study addsThere is little evidence for or against the effectiveness of over the counter cough medicinesAlthough cough medicines are generally well tolerated, they may be an unnecessary expenseRecommendation of over the counter cough medicines to patients is not justified by current evidence PMID:11834560

    Gene expression studies have consistently identified a HOXA-overexpressing cluster of T-cell acute lymphoblastic leukemias, but it is unclear whether these constitute a homogeneous clinical entity, and the biological consequences of HOXA overexpression have not been systematically examined. We characterized the biology and outcome of 55 HOXA-positive cases among 209 patients with adult T-cell acute lymphoblastic leukemia uniformly treated during the Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL)-2003 and -2005 studies. HOXA-positive patients had markedly higher rates of an early thymic precursor-like immunophenotype (40.8% versus 14.5%, P=0.0004), chemoresistance (59.3% versus 40.8%, P=0.026) and positivity for minimal residual disease (48.5% versus 23.5%, P=0.01) than the HOXA-negative group. These differences were due to particularly high frequencies of chemoresistant early thymic precursor-like acute lymphoblastic leukemia in HOXA-positive cases harboring fusion oncoproteins that transactivate HOXA. Strikingly, the presence of an early thymic precursor-like immunophenotype was associated with marked outcome differences within the HOXA-positive group (5-year overall survival 31.2% in HOXA-positive early thymic precursor versus 66.7% in HOXA-positive non-early thymic precursor, P=0.03), but not in HOXA-negative cases (5-year overall survival 74.2% in HOXA-negative early thymic precursor versus 57.2% in HOXA-negative non-early thymic precursor, P=0.44). Multivariate analysis further revealed that HOXA positivity independently affected event-free survival (P=0.053) and relapse risk (P=0.039) of chemoresistant T-cell acute lymphoblastic leukemia. These results show that the underlying mechanism of HOXA deregulation dictates the clinico-biological phenotype, and that the negative prognosis of early thymic precursor acute lymphoblastic leukemia is exclusive to HOXA-positive patients, suggesting that early treatment intensification is currently

    Background Mefenamic acid is a non-steroidal anti-inflammatory drug (NSAID). It is most often used for treating pain of dysmenorrhoea in the short term (seven days or less), as well as mild to moderate pain including headache, dental pain, postoperative and postpartum pain. It is widely available in many countries worldwide. Objectives To assess the efficacy of single dose oral mefenamic acid in acute postoperative pain, and any associated adverse events. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to December 2010. Selection criteria Single oral dose, randomised, double-blind, placebo-controlled trials of mefenamic acid for relief of established moderate to severe postoperative pain in adults. Data collection and analysis Studies were assessed for methodological quality and the data extracted by two review authors independently. Summed total pain relief (TOTPAR) or pain intensity difference (SPID) over 4 to 6 hours was used to calculate the number of participants achieving at least 50% pain relief. These derived results were used to calculate, with 95% confidence intervals, the relative benefit compared to placebo, and the number needed to treat (NNT) for one participant to experience at least 50% pain relief over 4 to 6 hours. Numbers of participants using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Information on adverse events and withdrawals was collected. Main results Four studies with 842 participants met the inclusion criteria; 126 participants were treated with mefenamic acid 500 mg, 67 with mefenamic acid 250 mg, 197 with placebo, and 452 with lignocaine, aspirin, zomepirac or nimesulide. Participants had pain following third molar extraction, episiotomy and orthopaedic surgery. The NNT for at least 50% pain relief over 6 hours with a single dose of mefenamic acid 500 mg compared to placebo was 4.0 (2

    Background Migraine is a common, disabling condition and a burden for the individual, health services and society. Many sufferers choose not to, or are unable to, seek professional help and rely on over-the-counter analgesics. Co-therapy with an antiemetic should help to reduce nausea and vomiting commonly associated with migraine headaches. Objectives To determine the efficacy and tolerability of aspirin, alone or in combination with an antiemetic, compared to placebo and other active interventions in the treatment of acute migraine headaches in adults. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies through 10 March 2010. Selection criteria We included randomised, double-blind, placebo- or active-controlled studies using aspirin to treat a discrete migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Numbers of participants achieving each outcome were used to calculate relative risk and numbers needed to treat (NNT) or harm (NNH) compared to placebo or other active treatment. Main results Thirteen studies (4222 participants) compared aspirin 900 mg or 1000 mg, alone or in combination with metoclopramide 10 mg, with placebo or other active comparators, mainly sumatriptan 50 mg or 100 mg. For all efficacy outcomes, all active treatments were superior to placebo, with NNTs of 8.1, 4.9 and 6.6 for 2-hour pain-free, 2-hour headache relief, and 24-hour headache relief with aspirin alone versus placebo, and 8.8, 3.3 and 6.2 with aspirin plus metoclopramide versus placebo. Sumatriptan 50 mg did not differ from aspirin alone for 2-hour pain-free and headache relief, while sumatriptan 100 mg was better than the combination of aspirin plus metoclopramide for 2-hour pain-free, but not headache relief; there were no data for 24-hour headache relief. Associated symptoms of nausea, vomiting

    Acute exercise can positively impact cognition. The present study examined the effect of acute high-intensity aerobic exercise on prefrontal-dependent cognitive performance and brain-derived neurotrophic factor (BDNF). Fifty-eight young adults were randomly assigned to one of two experimental groups: (a) an acute bout of high-intensity exercise (n=29) or (b) a non-exercise control (n=29). Participants in the exercise group improved performance on inhibitory control in Stroop interference and on cognitive flexibility in Trail Making Test (TMT) Part-B compared with participants in the control group and increased BDNF immediately after exercise. There was a significant relationship between BDNF and TMT Part-B on the pre-post change following exercise. These findings provide support for the association between improved prefrontal-dependent cognitive performance and increased BDNF in response to acute exercise. We conclude that the changes in BDNF concentration may be partially responsible for prefrontal-dependent cognitive functioning following an acute bout of exercise.

    Sinfrontal, a complex homeopathic medication, is popular in Germany for the treatment of ear, nose and throat and respiratory tract infections. Unlike many other homeopathic or herbal medications, the efficacy and safety of Sinfrontal has been demonstrated in a number of clinical studies of patients with sinusitis. To assess the cost effectiveness of Sinfrontal versus placebo in the treatment of adults with acute maxillary sinusitis (AMS) in Germany. A secondary objective was to assess the cost effectiveness of Sinfrontal versus standard treatment with antibacterials. Sinfrontal was compared with placebo in a cost-utility analysis based on data from a randomized controlled clinical trial over 3 weeks (Sinfrontal group: n = 57; placebo group: n = 56). Trial data were analysed from a societal perspective; resource use was valued with German unit costs for 2005. In a secondary analysis, the longer-term cost utility of Sinfrontal versus placebo was estimated over a total of 11 weeks based on an 8-week post-treatment observational phase. In addition, the cost effectiveness of Sinfrontal versus antibacterials was determined based on an indirect comparison of placebo-controlled trials. Sinfrontal led to incremental savings of euro 275 (95% CI 433, 103) per patient compared with placebo over 22 days, essentially due to the markedly reduced absenteeism from work (7.83 vs 12.9 workdays). Incremental utility amounted to 0.0087 QALYs (95% CI 0.0052, 0.0123), or 3.2 quality-adjusted life-days (QALDs). Bootstrapping showed that these findings were significant, with Sinfrontal being dominant in 99.9% of simulations. The results were robust to a number of sensitivity analyses. In the secondary analysis, Sinfrontal led to incremental cost savings of euro 511 and utility gains of 0.015 QALYs or 5.4 QALDs compared with placebo. Compared with antibacterials, Sinfrontal had a significantly higher cure rate (11% vs 59%; p < 0.001) at similar or lower costs. The results of this economic

    We examined the acute effect of physical exercise on prefrontal cortex activity in older adults using functional near-infrared spectroscopy (NIRS). Fourteen older adults visited our laboratory twice: once for exercise and once for the control condition. On each visit, subjects performed working memory tasks before and after moderate intensity exercise with a cycling ergo-meter. We measured the NIRS response at the prefrontal cortex during the working memory task. We found that physical exercise improved behavioral performance of the working memory task compared with the control condition. Moreover, NIRS analysis showed that physical exercise enhanced the prefrontal cortex activity, especially in the left hemisphere, during the working memory task. These findings suggest that the moderate intensity exercise enhanced the prefrontal cortex activity associated with working memory performance in older adults.

    Adults with acute lymphoblastic leukemia (ALL) are known to have inferior outcomes compared to the pediatric population. Although the reasons for this are likely manyfold, the agents utilized and the increased intensity of pediatric treatments compared to adult treatments are likely significant contributing factors. Asparaginase, an enzyme that converts asparagine to aspartic acid, forms the backbone of almost all pediatric regimens and works by depleting extracellular asparagine, which ALL cells are unable to synthesize. Asparaginase toxicities, which include hypersensitivity reactions, pancreatitis, liver dysfunction, and thrombosis, have hindered its widespread use in the adult population. Here, we review the toxicity and efficacy of asparaginase in adult patients with ALL. With the proper precautions, it is a safe and effective agent in the treatment of younger adults with ALL with response rates in the frontline setting ranging from 78% to 96%, compared to most trials showing a 4-year overall survival of 50% or better. The age cutoff for consideration of treatment with pediatric-inspired regimens is not clear, but recent studies show promise particularly in the adolescent and young adult population. New formulations of asparaginase are actively in development, including erythrocyte-encapsulated asparaginase, which is designed to minimize the toxicity and improve the delivery of the drug.

    Chewing reportedly contributes to satiation and satiety signals. Attempts to document and quantify this have led to small and inconsistent effects. The present trial manipulated oral processing effort though required chewing of gums of different hardness and measured appetitive sensations, energy intake, gastric emptying, GI transit time, and concentrations of glucose, insulin, GLP-1, ghrelin and pancreatic polypeptide. Sixty adults classified by sex and BMI (15 each of lean females, obese females, lean males and obese males) were tested in a randomized, controlled, cross-over trial with three arms. They chewed nothing, soft gum or hard gum for 15 min while sipping grape juice (10% of individual energy needs) containing acetaminophen and lactulose on one day each separated by 7 days. Electromyographic recordings and self-reports were obtained during and after chewing to quantify oral processing effort. Blood was sampled through an indwelling catheter and appetite ratings were obtained at baseline and at 0, 15, 30, 45, 60, 90, 120, 180 and 240 min after chewing initiation. Breath samples were collected at 10 min intervals for the first 2h and at 30 min intervals for the next 2h. No effects of chewing were observed for appetitive sensations or gut peptide concentrations. Energy intake tended to decline in lean and increase in obese participants so that daily energy intake differed significantly between the two groups when chewing either gum, while no difference was observed on the non-chewing day. Serum glucose and insulin were significantly lower at selected time points 90-240 min after chewing compared to baseline and the non-chewing day. These data indicate chewing effort does not affect appetitive sensations or gut peptide secretion, but may exert a small differential effect on acute energy intake in lean and obese individuals and lead to greater post-prandial declines of serum glucose and insulin.

    Background: The dopaminergic system is implicated in many mental processes and neuropsychiatric disorders. Pharmacologically, drugs with dopamine receptor antagonistic and agonistic effects are used, but their effects on functional brain metabolism are not well known. Methods: In this randomized crossover, placebo-controlled, and rater-blinded study, 25 healthy adults received an acute dose placebo substance (starch), quetiapine (dopamine receptor antagonist), or pramipexole (dopamine agonist of the nonergoline class) 1 hour before the experiment. Background-suppressed 2D pseudo-continuous arterial spin labeling was used to examine whole-brain baseline cerebral blood flow differences induced by the 3 substances. Results: We found that quetiapine reduced perfusion in the occipital (early visual areas) and bilateral cerebellar cortex relative to placebo. In contrast, quetiapine enhanced cerebral blood flow (relative to placebo) in the striatal system (putamen and caudate nucleus) but also in the supplementary motor area, insular-, prefrontal- as well as in the pre- and postcentral cortex. Pramipexole increased cerebral blood flow compared with placebo in the caudate nucleus, putamen, middle frontal, supplementary motor area, and brainstem (substantia nigra), but reduced cerebral blood flow in the posterior thalamus, cerebellum, and visual areas. Pramipexole administration resulted in stronger cerebral blood flow relative to quetiapine in the hypothalamus, cerebellum, and substantia nigra. Conclusions: Our results indicate that quetiapine and pramipexole differentially modulate regional baseline cerebral blood flow. Both substances act on the dopaminergic system, although they affect distinct regions. Quetiapine altered dopaminergic function in frontal, striatal, and motor regions. In contrast, pramipexole affected cerebral blood flow of the nigrostriatal (striatum and substantia nigra) dopaminergic, but less the fronto-insular system. PMID:27466220

    Objective: We sought to determine 30-day survival trends and prognostic factors following surgery for acute subdural hematomas (ASDHs) in England and Wales over a 20-year period. Summary of Background Data: ASDHs are still considered the most lethal type of traumatic brain injury. It remains unclear whether the adjusted odds of survival have improved significantly over time. Methods: Using the Trauma Audit and Research Network (TARN) database, we analyzed ASDH cases in the adult population (>16 yrs) treated surgically between 1994 and 2013. Two thousand four hundred ninety-eight eligible cases were identified. Univariable and multiple logistic regression analyses were performed, using multiple imputation for missing data. Results: The cohort was 74% male with a median age of 48.9 years. Over half of patients were comatose at presentation (53%). Mechanism of injury was due to a fall (<2 m 34%, >2 m 24%), road traffic collision (25%), and other (17%). Thirty-six per cent of patients presented with polytrauma. Gross survival increased from 59% in 1994 to 1998 to 73% in 2009 to 2013. Under multivariable analysis, variables independently associated with survival were year of injury, Glasgow Coma Scale, Injury Severity Score, age, and pupil reactivity. The time interval from injury to craniotomy and direct admission to a neurosurgical unit were not found to be significant prognostic factors. Conclusions: A significant improvement in survival over the last 20 years was observed after controlling for multiple prognostic factors. Prospective trials and cohort studies are expected to elucidate the distribution of functional outcome in survivors. PMID:27172128

    Racecadotril is a guideline-recommended treatment to alleviate symptoms of acute diarrhea. A systematic review of randomized studies was performed comparing efficacy and safety of treatment with racecadotril to that with placebo or active treatments in adults. In five double-blind studies, racecadotril and placebo had comparable tolerability, but racecadotril was more effective. This was consistent across multiple efficacy parameters including duration of diarrhea, number of diarrheic stools, abdominal pain, and meteorism; it was also consistent across countries in Africa, Asia, and Europe. In six randomized studies in outpatients comparing racecadotril to loperamide, resolution of symptoms occurred with similar speed and efficacy; however, racecadotril treatment was associated with less rebound constipation and less abdominal discomfort. The seventh comparative study performed in geriatric nursing home residents reported a superior efficacy of racecadotril. In direct comparison with Saccharomyces boulardii treatment, racecadotril exhibited similar tolerability but was more efficacious. One study compared racecadotril to octreotide in patients with acute diarrhea requiring hospitalization, rehydration, and antibiotic treatment; in this cohort, octreotide was more efficacious than racecadotril. In conclusion, in adults with acute diarrhea, racecadotril is more efficacious than placebo or S. boulardii, similarly efficacious as loperamide and, in patients with moderate to severe disease as add-on to antibiotics, less than octreotide. The tolerability of racecadotril is similar to that of placebo or S. boulardii and better than that of loperamide, particularly with regard to risk of rebound constipation. Taken together, these data demonstrate that racecadotril is a suitable treatment to alleviate symptoms of acute diarrhea in adults. PMID:27790616

    Adolescence is a critical developmental period associated with both increased vulnerability to substance abuse and maturation of certain brain regions important for learning and memory such as the hippocampus. In this study, we employed a hippocampus-dependent learning context pre-exposure facilitation effect (CPFE) paradigm in order to test the effects of acute nicotine on contextual processing during adolescence (post-natal day (PND) 38) and adulthood (PND 53). In Experiment 1, adolescent or adult C57BL6/J mice received either saline or one of three nicotine doses (0.09, 0.18, and 0.36mg/kg) prior to contextual pre-exposure and testing. Our results demonstrated that both adolescent and adult mice showed CPFE in the saline groups. However, adolescent mice only showed acute nicotine enhancement of CPFE with the highest nicotine dose whereas adult mice showed the enhancing effects of acute nicotine with all three doses. In Experiment 2, to determine if the lack of nicotine's effects on CPFE shown by adolescent mice is specific to the age when they are tested, mice were either given contextual pre-exposure during adolescence or adulthood and received immediate shock and testing during adulthood after a 15day delay. We found that both adolescent and adult mice showed CPFE in the saline groups when tested during adulthood. However, like Experiment 1, mice that received contextual pre-exposure during adolescence did not show acute nicotine enhancement except at the highest dose (0.36mg/kg) whereas both low (0.09mg/kg) and high (0.36mg/kg) doses enhanced CPFE in adult mice. Finally, we showed that the enhanced freezing response found with 0.36mg/kg nicotine in the 15-day experiment may be a result of decreased locomotor activity as mice that received this dose of nicotine traveled shorter distances in an open field paradigm. Overall, our results indicate that while adolescent mice showed normal contextual processing when tested both during adolescence and adulthood, they

    Abstract Objective To analyze and compare the health-related quality of life of adult survivors of acute lymphocytic leukemia and Wilms’ tumor amongst themselves and in relation to healthy participants. Methods Ninety participants aged above 18 years were selected and divided into three groups, each comprising 30 individuals. The Control Group was composed of physically healthy subjects, with no cancer history; and there were two experimental groups: those diagnosed as acute lymphocytic leukemia, and those as Wilms’ Tumor. Quality of life was assessed over the telephone, using the Medical Outcomes Study 36-Item Short Form Health Survey. Results Male survivors presented with better results as compared to female survivors and controls in the Vitality domain, for acute lymphocytic leukemia (p=0.042) and Wilms’ tumor (p=0.013). For acute lymphocytic leukemia survivors, in Social aspects (p=0.031), Mental health (p=0.041), and Emotional aspects (p=0.040), the latter also for survivors of Wilms’ tumor (p=0.040). The best results related to the Functional capacity domain were recorded for the experimental group that had a late diagnosis of acute lymphocytic leukemia. There were significant differences between groups except for the Social and Emotional domains for self-perceived health, with positive responses that characterized their health as good, very good, and excellent. Conclusion Survivors of acute lymphocytic leukemia showed no evidence of relevant impairment of health-related quality of life. The Medical Outcomes Study 36-Item Short Form Health Survey (via telephone) can be a resource to access and evaluate survivors. PMID:26537509

    Age-related differences in sensitivity to the acute effects of alcohol may play an important role in the increased risk for the development of alcoholism seen in teens that begin drinking at an early age. The present study evaluated the acute and protracted (hangover) effects of ethanol in adolescent (P33-P40) and adult (P100-P107) Wistar rats, using the cortical electroencephalogram (EEG). Six minutes of EEG was recorded during waking, 15 min after administration of 0, 1.5, or 3.0 g/kg ethanol, and for 3 h at 20 h post ethanol, during the rats' next sleep cycle. Significantly higher overall frontal and parietal cortical power was seen in a wide range of EEG frequencies in adolescent rats as compared to adult rats in their waking EEG. Acute administration of ethanol did not produce differences between adolescents and adults on behavioral measures of acute intoxication. However, it did produce a significantly less intense acute EEG response to ethanol in the theta frequencies in parietal cortex in the adolescents as compared to the adults. At 20 h following acute ethanol administration, during the rats' next sleep cycle, a decrease in slow-wave frequencies (1-4 Hz) was seen and the adolescent rats were found to display more reduction in the slow-wave frequencies than the adults did. The present study found that adolescent rats, as compared to adults, demonstrate low sensitivity to acute ethanol administration in the theta frequencies and more susceptibility to disruption of slow-wave sleep during hangover. These studies may lend support to the idea that these traits may contribute to increased risk for alcohol use disorders seen in adults who begin drinking in their early teenage years.

    2014-01-01

    Background Migraine is a common, disabling condition and a burden for the individual, health services and society. Many sufferers do not seek professional help, relying instead on over-the-counter analgesics. Co-therapy with an antiemetic should help to reduce symptoms commonly associated with migraine headaches. Objectives To determine efficacy and tolerability of ibuprofen, alone or in combination with an antiemetic, compared to placebo and other active interventions in the treatment of acute migraine headaches in adults. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies through 22 April 2010. Selection criteria We included randomised, double-blind, placebo- or active-controlled studies using self-administered ibuprofen to treat a migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Numbers of participants achieving each outcome were used to calculate relative risk and number needed to treat (NNT) or harm (NNH) compared to placebo or other active treatment. Main results Nine studies (4373 participants, 5223 attacks) compared ibuprofen with placebo or other active comparators; none combined ibuprofen with a self-administered antiemetic. All studies treated attacks with single doses of medication. For ibuprofen 400 mg versus placebo, NNTs for 2-hour pain-free (26% versus 12% with placebo), 2-hour headache relief (57% versus 25%) and 24-hour sustained headache relief (45% versus 19%) were 7.2, 3.2 and 4.0, respectively. For ibuprofen 200 mg versus placebo, NNTs for 2-hour pain-free (20% versus 10%) and 2-hour headache relief (52% versus 37%) were 9.7 and 6.3, respectively. The higher dose was significantly better for 2-hour headache relief than the lower dose. Soluble formulations of ibuprofen 400 mg were better than standard tablets for 1-hour, but not 2-hour headache relief

    In a double-blind, controlled randomized trial, 88 adult patients with acute diarrhea (more than three watery stools per day) received either 400 mg of nifuroxazide twice daily or placebo for 5 days. The mean duration of diarrhea in the nifuroxazide group was 2.09 days versus 3.26 days in the placebo group (p less than 0.004). The number of bowel movements per day diminished and mucus disappeared more quickly in patients treated by nifuroxazide than in patients of the placebo group. Nifuroxazide was well tolerated and no side effects were observed. Nifuroxazide is an effective therapy for acute diarrhea and can be prescribed from the onset of diarrhea without waiting for stool culture results which can be late or negative.

    Up to 60% of cases of equine colitis have no known cause. To improve understanding of the causes of acute colitis in horses, we hypothesized that Clostridium perfringens producing enterotoxin (CPE) and/or beta2 toxin (CPB2) are common and important causes of severe colitis in horses and/or that C. perfringens producing an as-yet-undescribed cytotoxin may also cause colitis in horses. Fecal samples from 55 horses (43 adults, 12 foals) with clinical evidence of colitis were evaluated by culture for the presence of Clostridium difficile, C. perfringens, and Salmonella. Feces were also examined by enzyme-linked immunosorbent assay (ELISA) for C. difficile A/B toxins and C. perfringens alpha toxin (CPA), beta2 toxin (CPB2), and enterotoxin (CPE). Five C. perfringens isolates per sample were genotyped for the following genes: cpa, cpb, cpb2 consensus, cpb2 atypical, cpe (enterotoxin), etx (epsilon toxin), itx (iota toxin), netB (necrotic enteritis toxin B), and tpeL (large C. perfringens cytotoxin). The supernatants of these isolates were also evaluated for toxicity for an equine cell line. All fecal samples were negative for Salmonella. Clostridium perfringens and C. difficile were isolated from 40% and 5.4% of samples, respectively. All fecal samples were negative for CPE. Clostridium perfringens CPA and CPB2 toxins were detected in 14.5% and 7.2% of fecal samples, respectively, all of which were culture-positive for C. perfringens. No isolates were cpe, etx, netB, or tpeL gene-positive. Atypical cpb2 and consensus cpb2 genes were identified in 15 (13.6%) and 4 (3.6%) of 110 isolates, respectively. All equine C. perfringens isolates showed far milder cytotoxicity effects than a CPB-producing positive control, although cpb2-positive isolates were slightly but significantly more cytotoxic than negative isolates. Based on this studied population, we were unable to confirm our hypothesis that CPE and CPB2-producing C. perfringens are common in horses with colitis in

    Background Codeine is an opioid metabolised to active analgesic compounds, including morphine. It is widely available by prescription, and combination drugs including low doses of codeine are commonly available without prescription. Objectives To assess the efficacy, the time to onset of analgesia, the time to use of rescue medication and any associated adverse events of single dose oral codeine in acute postoperative pain. Search methods We searched CENTRAL, MEDLINE, EMBASE and PubMed to November 2009. Selection criteria Single oral dose, randomised, double-blind, placebo-controlled trials of codeine for relief of established moderate to severe postoperative pain in adults. Data collection and analysis Studies were assessed for methodological quality and data independently extracted by two review authors. Summed total pain relief (TOTPAR) or pain intensity difference (SPID) over 4 to 6 hours were used to calculate the number of participants achieving at least 50% pain relief, which were used to calculate, with 95% confidence intervals, the relative benefit compared to placebo, and the number needed to treat (NNT) for one participant to experience at least 50% pain relief over 4 to 6 hours. Numbers using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Data on adverse events and withdrawals were collected. Main results Thirty-five studies were included (1223 participants received codeine 60 mg, 27 codeine 90 mg, and 1252 placebo). Combining all types of surgery (33 studies, 2411 participants), codeine 60 mg had an NNT of at least 50% pain relief over 4 to 6 hours of 12 (8.4 to 18) compared with placebo. At least 50% pain relief was achieved by 26% on codeine 60 mg and 17% on placebo. Following dental surgery the NNT was 21 (12 to 96) (15 studies, 1146 participants), and following other types of surgery the NNT was 6.8 (4.6 to 13) (18 studies, 1265 participants).

    Introduction Advanced Trauma Life Support (ATLS) protocols provide a common approach for trauma resuscitations. This was a quality review assessing compliance with ATLS protocols at a Level I trauma center; specifically whether the presence or absence of a trauma team leader (TTL) influenced adherence. Methods This retrospective study was conducted on adult major trauma patients with acute injuries over a one-year period in a Level I Canadian trauma center. Data were collected from the Alberta Trauma Registry, and adherence to ATLS protocols was determined by chart review. Results The study identified 508 patients with a mean Injury Severity Score of 24.5 (SD 10.7), mean age 39.7 (SD 17.6), 73.8% were male and 91.9% were involved in blunt trauma. The overall compliance rate was 81.8% for primary survey and 75% for secondary survey. The TTL group compared to non-TTL group was more likely to complete the primary survey (90.9% vs. 81.8%, p = 0.003), and the secondary survey (100% vs. 75%, p = 0.004). The TTL group was more likely than the non-TTL group to complete the following tasks: insertion of two large bore IVs (68.2% vs. 57.7%, p = 0.014), digital rectal exam (64.6% vs. 54.7%, p = 0.023), and head to toe exam (77% vs. 67.1%, p = 0.013). Mean times from emergency department arrival to diagnostic imaging were also significantly shorter in the TTL group compared to the non-TTL group, including times to pelvis xray (mean 68min vs. 107min, p = 0.007), CT chest (mean 133min vs. 172min, p = 0.005), and CT abdomen and pelvis (mean 136min vs. 173min, p = 0.013). Readmission rates were not significantly different between the TTL and non-TTL groups (3.5% vs. 4.5%, p = 0.642). Conclusions While many studies have demonstrated the effectiveness of trauma systems on outcomes, few have explored the direct influence of the TTL on ATLS compliance. This study demonstrated that TTL involvement during resuscitations was associated with improved

    Background The antifolate agent methotrexate is an important component of maintenance therapy in acute lymphoblastic leukemia, although methotrexate-related toxicity is often a reason for interruption of chemotherapy. Prediction of toxicity is difficult because of inter-individual variability susceptibility to antileukemic agents. Methotrexate interferes with folate metabolism leading to depletion of reduced folates. Design and Methods The aim of this study was to investigate the influence of polymorphisms for folate metabolizing enzymes with respect to toxicity and survival in adult patients with acute lymphoblastic leukemia treated with methotrexate maintenance therapy. To this purpose, we evaluated possible associations between genotype and hematologic and non-hematologic toxicity and effects on survival at 2 years of follow-up in patients with acute lymphoblastic leukemia. Results Polymorphisms in the genes encoding for methylenetetrahydrofolate reductase (MTHFR 677C>T) and in dihydrofolate reductase (DHFR 19 bp deletion) significantly increased the risk of hepatotoxicity in single (odds ratio 5.23, 95% confidence interval 1.13–21.95 and odds ratio 4.57, 95% confidence interval 1.01–20.77, respectively) and in combined analysis (odds ratio 6.82, 95% confidence interval 1.38–33.59). MTHFR 677C>T also increased the risk of leukopenia and gastrointestinal toxicity, whilst thymidylate synthase 28 bp repeat polymorphism increased the risk of anemia (odds ratio 8.48, 95% confidence interval 2.00–36.09). Finally, patients with MTHFR 677TT had a decreased overall survival rate (hazard ratio 2.37, 95% confidence interval 1.46–8.45). Conclusions Genotyping of folate polymorphisms might be useful in adult acute lymphoblastic leukemia to optimize methotrexate therapy, reducing the associated toxicity with possible effects on survival.

    Juvenile myelomonocytic leukemia (JMML), an overlap of myelodysplastic / myeloproliferative neoplasm, is an intractable pediatric myeloid neoplasm. Epigenetic regulation of transcription, particularly by CpG methylation, plays an important role in tumor progression, mainly by repressing tumor-suppressor genes. To clarify the clinical importance of aberrant DNA methylation, we studied the hypermethylation status of 16 target genes in the genomes of 92 patients with JMML by bisulfite conversion and the pryosequencing technique. Among 16 candidate genes, BMP4, CALCA, CDKN2A, and RARB exhibited significant hypermethylation in 72% (67/92) of patients. Based on the number of hypermethylated genes, patients were stratified into three cohorts based on an aberrant methylation score (AMS) of 0, 1–2, or 3–4. In the AMS 0 cohort, the 5-year overall survival (OS) and transplantation-free survival (TFS) were good (69% and 76%, respectively). In the AMS 1–2 cohort, the 5-year OS was comparable to that in the AMS 0 cohort (68%), whereas TFS was poor (6%). In the AMS 3–4 cohort, 5-year OS and TFS were markedly low (8% and 0%, respectively). Epigenetic analysis provides helpful information for clinicians to select treatment strategies for patients with JMML. For patients with AMS 3–4 in whom hematopoietic stem cell transplantation does not improve the prognosis, alternative therapies, including DNA methyltransferase inhibitors and new molecular-targeting agents, should be established as treatment options.

    The cytidine analogues azacytidine and 5-aza-2’-deoxycytidine (decitabine) are commonly used to treat myelodysplastic syndromes, with or without a myeloproliferative component. It remains unclear whether the response to these hypomethylating agents results from a cytotoxic or an epigenetic effect. In this study, we address this question in chronic myelomonocytic leukaemia. We describe a comprehensive analysis of the mutational landscape of these tumours, combining whole-exome and whole-genome sequencing. We identify an average of 14 ± 5 somatic mutations in coding sequences of sorted monocyte DNA and the signatures of three mutational processes. Serial sequencing demonstrates that the response to hypomethylating agents ismore » associated with changes in DNA methylation and gene expression, without any decrease in the mutation allele burden, nor prevention of new genetic alteration occurence. Lastly, our findings indicate that cytosine analogues restore a balanced haematopoiesis without decreasing the size of the mutated clone, arguing for a predominantly epigenetic effect.« less

    A major barrier to successful cancer immunotherapy is the tumor's ability to induce T-cell tolerance by exploiting host regulatory mechanisms. Having discovered the DC-HIL receptor, which inhibits T-cell responses by binding to syndecan-4 on effector T cells, we posited the DC-HIL/syndecan-4 pathway to have an important role in cancer promotion. Among DC-HIL(+) myelomonocytic cells, during growth of implanted mouse melanoma, CD11b(+)Gr1(+) cells were the most expanded population and the most potent at suppressing T-cell activation. Deletion of the DC-HIL gene or infusion of anti-DC-HIL mAb abrogated these cells' suppressor function and expansion, and markedly diminished melanoma growth and metastasis. IL-1β and IFN-γ were elevated in mice bearing melanoma, and concurrent exposure to both cytokines optimally induced DC-HIL expression by tumor-infiltrating CD11b(+)Gr1(+) cells. Ligation of DC-HIL transduced phosphorylation of its intracellular immunoreceptor tyrosine-based activation motif, which in turn induced intracellular expression of IFN-γ and inducible nitric oxide synthase (iNOS), known to mediate T-cell suppression by CD11b(+)Gr1(+) cells. Thus, DC-HIL is the critical mediator of these cells' suppressor function in melanoma-bearing mice and a potential target for improving melanoma immunotherapy.

    The aim of this study was to describe the characteristics and outcome in a group of pediatric patients with hematological malignancies who developed hemophagocytosis at diagnosis or during the disease course. Eight patients with hematological malignancy and associated hemophagocytosis were included. The initial diagnosis was juvenile myelomonocytic leukemia (JMML) in five, nonlymphoblastic leukemia (ANLL) in two, and T-cell lymphoma associated with myeloproliferative syndrome in one patient. Hemophagocytosis was concomitantly present at the time of diagnosis of the primary disease in four of the five patients with JMML and in the two patients with ANLL. Three had abnormalities related to chromosome 8 [(trisomy 8, monosomy 8, and t (8;13) (p11; p12)], and one had inversion 16. Multiple chromosomal losses were present in one patient, including both chromosomes 8 and 16. Bone marrow karyotyping revealed 46, XX; 47, XXX mosaicism in one patient. Two patients had PTPN11 mutation and one patient k-RAS mutation. The patients with JMML and neurofibromatosis (n = 2), the patient with lymphoma and t (8;13) positive AML, and a fourth patient with PTPN11 mutation did not remit and had unfavorable outcomes.

    We analyzed the mutational hotspot region of SRSF2 (Pro95) in 275 cases with chronic myelomonocytic leukemia (CMML). In addition, ASXL1, CBL, EZH2, JAK2V617F, KRAS, NRAS, RUNX1, and TET2 mutations were investigated in subcohorts. Mutations in SRSF2 (SRSF2mut) were detected in 47% (129 of 275) of all cases. In detail, 120 cases had a missense mutation at Pro95, leading to a change to Pro95His, Pro95Leu, Pro95Arg, Pro95Ala, or Pro95Thr. In 9 cases, 3 new in/del mutations were observed: 7 cases with a 24-bp deletion, 1 case with a 3-bp duplication, and 1 case with a 24-bp duplication. In silico analyses predicted a damaging character for the protein structure of SRSF2 for all mutations. SRSF2mut was correlated with higher age, less pronounced anemia, and normal karyotype. SRSF2mut and EZH2mut were mutually exclusive, but SRSF2mut was associated with TET2mut. In the total cohort, no effect of SRSF2mut on survival was observed. However, in the RUNX1mut subcohort, SRSF2 Pro95His had a favorable effect on overall survival. This comprehensive mutation analysis found that 93% of all patients with CMML carried at least 1 somatic mutation in 9 recurrently mutated genes. In conclusion, these data show the importance of SRSF2mut as new diagnostic marker in CMML. PMID:22919025

    Trisomy 8 (+8) is one of the most common cytogenetic abnormalities in adult patients with acute myeloid leukemia (AML). However, the outcome of allogeneic hematopoietic stem cell transplantation (HSCT) in adult patients with AML harboring +8 remains unclear. To evaluate, the outcome and prognostic factors in patients with AML harboring +8 as the only chromosomal abnormality or in association with other abnormalities, we retrospectively analyzed the Japanese registration data of 631 adult patients with AML harboring +8 treated with allogeneic HSCT between 1990 and 2013. In total, 388 (61%) patients were not in remission at the time of HSCT. With a median follow-up of 38.5 months, the probability of overall survival and the cumulative incidence of relapse at 3 years were 40 and 34%, respectively. In the multivariate analysis, two or more additional cytogenetic abnormalities and not being in remission at the time of HSCT were significantly associated with a higher overall mortality and relapse. Nevertheless, no significant impact on the outcome was observed in cases with one cytogenetic abnormality in addition to +8. Although more than 60% of the patients received HSCT when not in remission, allogeneic HSCT offered a curative option for adult patients with AML harboring +8.

    Adult giant cell hepatitis (AGCH) is a rare event and only about 100 cases have been reported within the last 20 years. The AGCH has been observed in association with viral infection, drug reactions or autoimmune disorders but in many cases its etiology remains unclear. AGCH manifests clinically as severe form of hepatitis histologically characterized by diffuse giant cell transformation of hepatocytes. We report the case of a 39-yr-old man with acute community-acquired hepatitis without previous pathology of the liver. Laboratory data revealed slight hypergammaglobulinemia and high titer of anti-smooth-muscle antibody with negative serology of hepatotropic viruses and absence of other known causes of hepatitis. Preliminary diagnosis of autoimmune hepatitis was established, additionally confirmed by excellent clinical and biochemical improvement during corticosteroid treatment. A liver biopsy showed the typical findings of panlobular syncytial giant cell hepatitis and positive HCV-RNA both in serum and liver. The above verified the diagnosis of acute type C hepatitis manifested histologically as adult giant cell hepatitis. After three months of treatment we withdrew corticosteroids as spontaneous clearance of HCV occurred and the lack of autoantibodies in serum as well as significant improvement of liver histology was ascertained. Within 30 months of the follow-up we have not observed biochemical and immunological abnormalities and control liver biopsy has shown no signs of hepatitis.

    Survival for adults and children with acute lymphoblastic leukaemia has risen substantially in recent years because use of improved risk-directed treatments and supportive care has widened. In nearly all developed countries, multidisciplinary panels of leukaemia experts have formulated clinical practice guidelines in which standard treatment approaches are recommended on the basis of current evidence. However, those guidelines do not take into account resource limitations in low-income countries, including financial and technical challenges. In Asia, huge disparities in economy and infrastructure exist between countries, and even among different regions in some large countries. At a consensus session held as part of the 2013 Asian Oncology Summit in Bangkok, Thailand, a panel of experts summarised recommendations for management of adult and paediatric acute lymphoblastic leukaemia. Strategies were developed for Asian countries on the basis of available financial, skill, and logistical resources and were stratified in a four-tier system according to the resources available in a particular country or region (basic, limited, enhanced, and maximum).

    The factors responsible for the conjunctivitis and iritis associated with acute ocular infection and post enteric inflammatory disease are not fully known. The pro-inflammatory activity of unilateral topical application of muramyl dipeptide (MDP; the smallest bio-active Gram-positive and Gram-negative bacterial cell wall component) was investigated in adult rabbits. The resultant bilateral conjunctivitis/iritis and pyogenic responses were characterized. Bilateral symptoms were graded by slit lamp examinations; tear fluid, Schirmer tests (tear production), blood and aqueous humor (AH) samples were obtained from MDP-treated and untreated rabbits. MDP concentration, gamma-glutamyltranspeptidase activity (GGT; key enzyme in glutathione recapture, xenobiotic detoxification, eicosanoid synthesis and neutrophil function), protein concentration, and tear cell density, cytology, and immunofluorescent antibody reactivity to GGT and calreticulin (CRT; MDP-binding protein) were determined. MDP was cleared from ipsilateral tears and serum by 6 h, but was undetected in mock-treated contralateral tears. Bilateral signs of acute transient pyogenic conjunctivitis, characterized by tearing, lid edema, conjunctival hyperemia, chemosis and leukocytic infiltrate with iritis (erythema and aqueous flare) were detected. Milder symptoms occurred in the mock-treated contralateral eyes. Bilateral symptoms, tear production, tear protein, GGT activity, and mucopurulent discharge (containing up to 2.5-5.0 × 10(6) cells/mL) were elevated 4-8 h post MDP and resolved to near pre-treatment levels by 24 h. Tear GGT activity and protein levels were higher in MDP-treated and mock-treated contralateral eyes than in eyes of untreated adult rabbits (p's < 0.001). Elevated tear GGT activity was associated with histopathology and increased vascular and epithelial permeability to serum protein, GGT-positive epithelia cells, macrophages and heterophils.

    We assessed the clinical effectiveness and safety of CKI (compound Kushen injection) plus standard induction chemotherapy for treating adult acute leukemia (AL). We randomly assigned 332 patients with newly diagnosed AL to control (n = 165, receiving DA (daunorubicin and cytarabine) or hyper-CVAD (fractionated cyclophosphamide, doxorubicin, vincristine, and dexamethasone)) or treatment (n = 167, receiving CKI and DA or hyper-CVAD) groups. Posttreatment, treatment group CD3+, CD4+, CD4+/CD8+, natural killer (NK) cell, and immunoglobulin (IgG, IgA, and IgM) levels were significantly higher than those of the control group (p < 0.05), and CD8+ levels were lower in the treatment group than in the control group (p < 0.05). Treatment group interleukin- (IL-) 4 and IL-10 levels were significantly higher compared to the control posttreatment (both p < 0.05) as were complete remission, overall response, and quality of life (QoL) improvement rates (p < 0.05). The control group had more incidences of grade 3/4 hematologic and nonhematologic toxicity (p < 0.05). Responses to induction chemotherapy, QoL improvement, and adverse events incidence between control group patients with acute myeloid leukemia and acute lymphocytic leukemia were not significantly different. CKI plus standard induction chemotherapy is effective and safe for treating AL, possibly by increasing immunologic function. PMID:27738441

    Background Migraine is a highly disabling condition for the individual and also has wide-reaching implications for society, healthcare services, and the economy. Sumatriptan is an abortive medication for migraine attacks, belonging to the triptan family. Objectives To determine the efficacy and tolerability of oral sumatriptan compared to placebo and other active interventions in the treatment of acute migraine attacks in adults. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, online databases, and reference lists for studies through 13 October 2011. Selection criteria We included randomised, double-blind, placebo- and/or active-controlled studies using oral sumatriptan to treat a migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. We used numbers of participants achieving each outcome to calculate relative risk (or ‘risk ratio’) and numbers needed to treat to benefit (NNT) or harm (NNH) compared to placebo or a different active treatment. Main results Sixty-one studies (37,250 participants) compared oral sumatriptan with placebo or an active comparator. Most of the data were for the 50 mg and 100 mg doses. Sumatriptan surpassed placebo for all efficacy outcomes. For sumatriptan 50 mg versus placebo the NNTs were 6.1, 7.5, and 4.0 for pain-free at two hours and headache relief at one and two hours, respectively. NNTs for sustained pain-free and sustained headache relief during the 24 hours postdose were 9.5 and 6.0, respectively. For sumatriptan 100 mg versus placebo the NNTs were 4.7, 6.8, 3.5, 6.5, and 5.2, respectively, for the same outcomes. Results for the 25 mg dose were similar to the 50 mg dose, while sumatriptan 100 mg was significantly better than 50 mg for pain-free and headache relief at two hours, and for sustained pain-free during 24 hours.

    The tumor necrosis-inducing factor (TNF) found in sera of Corynebacterium parvum-treated, endotoxin-stressed BALB/C and outbred albino CD-1 mice has been purified to a single band of protein by polyacrylamide gel electrophoresis after identification and removal of contaminating albumin and transferrin. This purified TNF has a molecular weight of 140,000, is glycoprotein in nature, and migrates on free electrophoresis as an alpha 2-globulin. TNF activity was continuously monitored during purification by bioassay in vitro (tumor cell lysis) and was confirmed by demonstration of induction of tumor necrosis in vivo. A single target tumor cell line, murine myelomonocytic leukemia (WEHI/3), was used in both assays. In the in vivo assay, controls were heat-inactivated samples of TNF. As additional controls, a line of TNF-resistant WEHI/3 cells was used in the in vitro assay. Results from in vivo radiolabeling of TNF-sensitive and TNF-resistant cells indicated a difference between their cytoplasmic peptide profiles. Optimal TNF production was not altered in C. parvum-endotoxin-treated mice by treatment with silica, a substance that is specifically toxic for macrophages. Exposure of mice to 650 rad whole-body radiation, which is not markedly damaging to macrophage elements in the reticuloendothelial system, completely abrogated the ability of the mice to produce TNF after C. parvum-endotoxin treatment. These findings suggest that in the sera of C. parvum-endotoxin-treated mice the protein that induces necrosis in tumors may not be of macrophage origin.

    Chronic myelomonocytic leukemia (CMML) is a myelodysplastic/myeloproliferative neoplasm with variable clinical course. To predict the clinical outcome, we previously developed a CMML-specific prognostic scoring system (CPSS) based on clinical parameters and cytogenetics. In this work, we tested the hypothesis that accounting for gene mutations would further improve risk stratification of CMML patients. We therefore sequenced 38 genes to explore the role of somatic mutations in disease phenotype and clinical outcome. Overall, 199 of 214 (93%) CMML patients carried at least 1 somatic mutation. Stepwise linear regression models showed that these mutations accounted for 15% to 24% of variability of clinical phenotype. Based on multivariable Cox regression analyses, cytogenetic abnormalities and mutations in RUNX1, NRAS, SETBP1, and ASXL1 were independently associated with overall survival (OS). Using these parameters, we defined a genetic score that identified 4 categories with significantly different OS and cumulative incidence of leukemic evolution. In multivariable analyses, genetic score, red blood cell transfusion dependency, white blood cell count, and marrow blasts retained independent prognostic value. These parameters were included into a clinical/molecular CPSS (CPSS-Mol) model that identified 4 risk groups with markedly different median OS (from >144 to 18 months, hazard ratio [HR] = 2.69) and cumulative incidence of leukemic evolution (from 0% to 48% at 4 years, HR = 3.84) (P < .001). The CPSS-Mol fully retained its ability to risk stratify in an independent validation cohort of 260 CMML patients. In conclusion, integrating conventional parameters and gene mutations significantly improves risk stratification of CMML patients, providing a robust basis for clinical decision-making and a reliable tool for clinical trials.

    Purpose To conduct a phase I clinical trial exploring the safety and efficacy of ruxolitinib, a JAK1/2 inhibitor, for chronic myelomonocytic leukemia (CMML). Experimental Design Patients with CMML-1 were included without regard to previous therapy. Key exclusion criteria included an absolute neutrophil count (ANC) <0.25 × 103 cells/dL and a platelet count <35 × 103 cells/dL. Four cohorts were enrolled using a "rolling six" study design, with doses ranging from 5 to 20 mg twice daily of ruxolitinib in 5-mg dose escalations. Results Between March 2013 and January 2015, 20 patients were enrolled and treated with ruxolitinib. Seventy percent of patients had the proliferative subtype and 47% had higher risk disease by the Global MD Anderson Scoring System. Eight patients (42%) received a prior hypomethylating agent. No dose-limiting toxicities for ruxolitinib were identified. One subject had grade (G)3 thrombocytopenia with no other drug-associated G3 or G4 adverse events. The mean duration of therapy was 122 days (range, 28–409 days). Four had hematologic improvement and one patient had a partial response per 2006 International Working Group (IWG) criteria. Five of 9 patients with splenomegaly had a reduction in spleen size. Ten of 11 patients with reported disease-related symptoms had clinically meaningful or complete resolution. When combining IWG and spleen responses, a total response rate of 35% (n = 7) was identified. Correlative analysis demonstrated a reduction in inflammatory cytokines and GM-CSF–dependent STAT5 phosphorylation. Conclusions The recommended phase II dose of ruxolitinib is 20 mg twice daily. We demonstrate that ruxolitinib has promising activity in CMML with particular benefit in those with disease-related B symptoms that warrants further study. PMID:26858309

    Double cord blood transplantation extends the use of cord blood to adults for whom a single unit is not available, but the procedure is limited by its cost. To evaluate outcomes and cost-effectiveness of double compared to single cord blood transplantation, we analyzed 134 transplants in adults with acute leukemia in first remission. Transplants were performed in France with reduced intensity or myeloablative conditioning regimens. Costs were estimated from donor search to 1 year after transplantation. A Markov decision analysis model was used to calculate quality-adjusted life-years and cost-effectiveness ratio within 4 years. The overall survival at 2 years after single and double cord blood transplants was 42% versus 62%, respectively (P=0.03), while the leukemia-free-survival was 33% versus 53%, respectively (P=0.03). The relapse rate was 21% after double transplants and 42% after a single transplant (P=0.006). No difference was observed for non-relapse mortality or chronic graft-versus-host-disease. The estimated costs up to 1 year after reduced intensity conditioning for single and double cord blood transplantation were € 165,253 and €191,827, respectively. The corresponding costs after myeloablative conditioning were € 192,566 and € 213,050, respectively. Compared to single transplants, double cord blood transplantation was associated with supplementary costs of € 21,302 and € 32,420 up to 4 years, but with increases in quality-adjusted life-years of 0.616 and 0.484, respectively, and incremental cost-effectiveness ratios of € 34,581 and €66,983 in the myeloablative and reduced intensity conditioning settings, respectively. Our results showed that for adults with acute leukemia in first complete remission in France, double cord transplantation is more cost-effective than single cord blood transplantation, with better outcomes, including quality-adjusted life-years.

    2005-01-01

    Background: Current guidelines recommend the use of a combination of inhaled ß2 agonists and anticholinergics, particularly for patients with acute severe or life threatening asthma in the emergency setting. However, this statement is based on a relatively small number of randomised controlled trials and related systematic reviews. A review was undertaken to incorporate the more recent evidence available about the effectiveness of treatment with a combination of ß2 agonists and anticholinergics compared with ß2 agonists alone in the treatment of acute asthma. Methods: A search was conducted of all randomised controlled trials published before April 2005. Results: Data from 32 randomised controlled trials (n = 3611 subjects) showed significant reductions in hospital admissions in both children (RR = 0.73; 95% CI 0.63 to 0.85, p = 0.0001) and adults (RR = 0.68; 95% CI 0.53 to 0.86, p = 0.002) treated with inhaled anticholinergic agents. Combined treatment also produced a significant increase in spirometric parameters 60–120 minutes after the last treatment in both children (SMD = –0.54; 95% CI –0.28 to –0.81, p = 0.0001) and adults (SMD = –0.36; 95% CI –0.23 to –0.49, p = 0.00001). Conclusions: This review strongly suggests that the addition of multiple doses of inhaled ipratropium bromide to ß2 agonists is indicated as the standard treatment in children, adolescents, and adults with moderate to severe exacerbations of asthma in the emergency setting.

    Acute kidney injury after cardiac surgery with cardiopulmonary bypass is a common and serious complication and it is associated with increased morbidity and mortality. Diagnosis of acute kidney injury is based on the serum creatinine levels which rise several hours to days after the initial injury. Thus, novel biomarkers that will enable faster diagnosis are needed in clinical practice. There are numerous urine and serum proteins that indicate kidney injury and are under extensive research. Despite promising basic research results and assembled data, which indicate superiority of some biomarkers to creatinine, we are still awaiting clinical application. PMID:27212976

    The authors present an unusual case of an acute swelling of the lower lip and septicemia in a 35-year-old, recent immigrant male arriving from India. The patient presented in our emergency department with a 48-hour history of a worsening, painful swelling of the lower lip. On presentation, he was pyrexial and the lip was found to be acutely inflamed with honey-colored crusting, pustular lesions, and induration . A diagnosis of impetigo leading to necrosis of the lip was established, a rare phenomenon potentially resulting in significant tissue destruction. Appropriate medical management achieved a good outcome and prevented disabling tissue loss of the orofacial region.

    Manganese chloride (MnCl2) is capable of stimulating luteinizing hormone releasing hormone (LHRH) secretion in adult male Sprague-Dawley rats through the activation of the hypothalamic nitric oxide/cyclic guanosine monophosphate (cGMP)/protein kinase G pathway. The present study aimed to determine the involvement of specific neurotransmitters involved in this action. Our results indicate that dopamine, but not glutamic acid and prostaglandinds, mediates the MnCl2 stimulated secretion of LHRH from medial basal hypothalami in vitro, as well as increases the activity of nitric oxide synthase. Furthermore, a biphasic response was observed in that gamma aminobutyric acid (GABA) release was also increased, which acts to attenuate the MnCl2 action to stimulate LHRH secretion. Although it is clear that manganese (Mn+2) can acutely induce LHRH secretion in adult males, we suggest that the additional action of MnCl2 to release GABA, a LHRH inhibitor, may ultimately contribute to suppressed reproductive function observed in adult animals following exposure to high chromic levels of Mn+2.

    Patients with acute lymphoblastic leukaemia (ALL) after cytotoxic chemotherapy or haematopoietic stem cell transplantation (HSCT) are at risk for life-threatening invasive fungal disease (IFD). The aim was to evaluate the characteristics, antifungal therapy and outcome of adult patients with ALL after chemotherapy or HSCT receiving caspofungin empirically in a clinical setting. Retrospective chart reviews were conducted at nine large tertiary care centres in Germany. Adult patients with ALL treated empirically with caspofungin according to the product label between 2006 and 2012 were eligible. Data were extracted as case reports. In total, 25 patients (12 males, 13 females; median age 37 years; 19 with B-ALL, 6 with T-ALL) with 28 treatment episodes because of suspected IFD (18 episodes after chemotherapy, 10 episodes after allogeneic HSCT) were included in the analysis. Empirical caspofungin therapy (median duration: 19 days, range 1-105 days) was given as first-line monotherapy in 20 (71.4%), second-line monotherapy in five (17.9%) and combination therapy in three (10.7%) episodes respectively. Therapy rated successful according to the physician's overall assessment (inflammatory parameters, clinical symptoms): 20 (95%) of 21 evaluable episodes with therapy duration of at least 8 days. Empirical caspofungin appears to be an effective therapeutic option in critically ill adult ALL patients with suspected IFD in clinical practice.

    Stressful experiences modify activity in areas of the brain involved in the rewarding effects of psychostimulants. In the present study we evaluated the influence of acute social defeat (ASD) on the conditioned rewarding effects of cocaine in adolescent (PND 29-32) and adult (PND 50-53) male mice in the conditioned place preference (CPP) paradigm. Experimental mice were exposed to social defeat in an agonistic encounter before each session of conditioning with 1mg/kg or 25mg/kg of cocaine. The effects of social defeat on corticosterone levels were also evaluated. Adult mice exposed to ASD showed an increase in the conditioned reinforcing effects of cocaine. Only these mice developed cocaine-induced CPP with the subthreshold dose of cocaine, and they needed a higher number of extinction sessions for the 25mg/kg cocaine-induced CPP to be extinguished. In adolescent mice, on the other hand, ASD reduced the conditioned reinforcing effects of cocaine, since CPP was not produced with the lower dose of cocaine and was extinguished faster when they were conditioned with 25mg/kg. Adult mice exposed to social defeat displayed higher levels of corticosterone than their controls and adolescent mice. Our results confirm that the effect of social defeat stress on the acquisition and reinstatement of the CPP induced by cocaine varies depending on the age at which this stress is experienced.

    The effects of acute aerobic exercise on cognitive functions in humans have been the subject of much investigation; however, these studies are limited by several factors, including a lack of randomized controlled designs, focus on only a single cognitive function, and testing during or shortly after exercise. Using a randomized controlled design, the present study asked how a single bout of aerobic exercise affects a range of frontal- and medial temporal lobe-dependent cognitive functions and how long these effects last. We randomly assigned 85 subjects to either a vigorous intensity acute aerobic exercise group or a video watching control group. All subjects completed a battery of cognitive tasks both before and 30, 60, 90, or 120 min after the intervention. This battery included the Hopkins Verbal Learning Test-Revised, the Modified Benton Visual Retention Test, the Stroop Color and Word Test, the Symbol Digit Modalities Test, the Digit Span Test, the Trail Making Test, and the Controlled Oral Word Association Test. Based on these measures, composite scores were formed to independently assess prefrontal cortex- and hippocampal-dependent cognition. A three-way mixed Analysis of Variance was used to determine whether differences existed between groups in the change in cognitive function from pre- to post-intervention testing. Acute exercise improved prefrontal cortex- but not hippocampal-dependent functioning, with no differences found between delay groups. Vigorous acute aerobic exercise has beneficial effects on prefrontal cortex-dependent cognition and these effects can last for up to 2 hr after exercise.

    The availability of alternative sources of stem cells including most recently T-replete haploidentical marrow or peripheral blood, and the increasing use of reduced-intensity conditioning (RIC), renders feasible an allogeneic transplant to almost all patients with acute leukemia up to 70 years of age. Autologous stem cell transplantation (ASCT) for consolidation of complete remission (CR), however, offers in some circumstances an alternative option. Although associated with a higher relapse rate, autologous transplant benefits from a lower non-relapse mortality, the absence of graft-versus-host disease (GVHD), and a better quality of life for long-term survivors. The recent use of intravenous busulfan (IVBU) with high-dose melphalan, better monitoring of minimal residual disease (MRD), and maintenance therapy post autografting bring new interest. Few retrospective studies compared the outcome following alternative donor versus autologous transplants for remission consolidation. Genoidentical and phenoidentical allogeneic stem cell transplantations are undisputed gold standards, but there are no data showing the superiority of alternative allogeneic donor over autologous transplantation, at the time of undetectable MRD, in patients with good- and intermediate-1 risk acute myelocytic leukemia (AML) in first complete remission (CR1), acute promyelocytic leukemia in second complete remission (CR2), and Philadelphia chromosome-positive (Ph(+)) acute lymphocytic leukemia (ALL).

    Brief neonatal handling permanently alters hypothalamic-pituitary-adrenal axis function resulting in increased ability to cope with stress. Since stress is known to affect cognitive abilities, in the present study we investigated the effect of brief (15 min) handling on learning and memory in the Morris water maze, following exposure to an acute restraint stress either before training or recall. Exposure of non-handled rats to the acute stress prior to training resulted in quicker learning of the task, than in the absence of the stressor. When acute stress preceded acquisition, male handled rats showed an overall better learning performance, and both sexes of handled animals were less impaired in the subsequent memory trial, compared to the respective non-handled. In addition, the number of neurons immunoreactive for GR was higher in all areas of Ammon's horn of the handled rats during the recall. In contrast, the number of neurons immunoreactive for MR was higher in the CA1 and CA2 areas of the non-handled males. When the acute restraint stress was applied prior to the memory test, neonatal handling was not effective in preventing mnemonic impairment, as all animal groups showed a similar deficit in recall. In this case, no difference between handled and non-handled rats was observed in the number of GR positive neurons in the CA2 and CA3 hippocampal areas during the memory test. These results indicate that early experience interacts with sex and acute stress exposure in adulthood to affect performance in the water maze. Hippocampal corticosterone receptors may play a role in determining the final outcome.

    Background Stress and stress hormones modulate memory formation in various ways that are relevant to our understanding of stress-related psychopathology, such as posttraumatic stress disorder (PTSD). Particular relevance is attributed to efficient memory formation sustained by the hippocampus and parahippocampus. This process is thought to reduce the occurrence of intrusions and flashbacks following trauma, but may be negatively affected by acute stress. Moreover, recent evidence suggests that the efficiency of visuo-spatial processing and learning based on the hippocampal area is related to PTSD symptoms. Objective The current study investigated the effect of acute stress on spatial configuration learning using a spatial contextual cueing task (SCCT) known to heavily rely on structures in the parahippocampus. Method Acute stress was induced by subjecting participants (N = 34) to the Maastricht Acute Stress Test (MAST). Following a counterbalanced within-subject approach, the effects of stress and the ensuing hormonal (i.e., cortisol) activity on subsequent SCCT performance were compared to SCCT performance following a no-stress control condition. Results Acute stress did not impact SCCT learning overall, but opposing effects emerged for high versus low cortisol responders to the MAST. Learning scores following stress were reduced in low cortisol responders, while high cortisol-responding participants showed improved learning. Conclusions The effects of stress on spatial configuration learning were moderated by the magnitude of endogenous cortisol secretion. These findings suggest a possible mechanism by which cortisol responses serve an adaptive function during stress and trauma, and this may prove to be a promising route for future research in this area.

    Yawning is a familiar and phylogenetically widespread phenomenon, but no consensus exists regarding its functional significance. We tested the hypothesis that yawning communicates to others a transition from a state of physiological and/or psychological arousal (for example, due to action of a stressor) to a more relaxed state. This arousal reduction hypothesis predicts little yawning during arousal and more yawning (above baseline) during and after down-regulation of arousal. Experimental capture-restraint tests with wild adult Nazca boobies (Sula granti), a seabird, increased yawning frequency after release from restraint, but yawning was almost absent during tests. Natural maltreatment by non-parental adults also increased yawning by nestlings, but only after the maltreatment ended and the adult left. CORT (corticosterone) was a logical a priori element of the stress response affecting the stressor-yawning relationship under the arousal reduction hypothesis, and cannot be excluded as such for adults in capture-restraint tests but is apparently unimportant for nestlings being maltreated by adults. The arousal reduction hypothesis unites formerly disparate results on yawning: its socially contagious nature in some taxa, its clear pharmacological connection to the stress response, and its temporal linkage to transitions in arousal between consciousness and sleep.

    What is the central question of this study? Neurocognitive functions can be enhanced by acute aerobic exercise, which could be associated with changes in serum brain-derived neurotrophic factor (BDNF) concentrations. We aimed to explore acute exercise-induced changes in BDNF concentrations, neuropsychological and neurophysiological performances when individuals with different levels of cardiorespiratory fitness performed a cognitive task. What is the main finding and its importance? Only young adults with higher cardiorespiratory fitness could attain switching cost and neurophysiological benefits via acute aerobic exercise. The mechanisms might be fitness dependent. Although acute aerobic exercise could enhance serum BDNF concentrations, changes in peripheral BDNF concentrations could not be the potential factor involved in the beneficial effects on neurocognitive performance. This study investigated the effects of acute aerobic exercise on neuropsychological and neurophysiological performances in young adults with different cardiorespiratory fitness levels when performing a task-switching protocol and explored the potential associations between acute aerobic exercise-induced changes in serum brain-derived neurotrophic factor (BDNF) concentrations and various neurocognitive outcomes. Sixty young adults were categorized into one control group (i.e. non-exercise-intervention; n = 20) and two exercise-intervention (EI) groups [i.e. higher (EIH , n = 20) and lower (EIL , n = 20) cardiorespiratory fitness] according to their maximal oxygen consumption. At baseline and after either an acute bout of 30 min of moderate-intensity aerobic exercise or a control period, the neuropsychological and neurophysiological performances and serum BDNF concentrations were measured when the participants performed a task-switching protocol involving executive control and greater demands on working memory. The results revealed that although acute aerobic exercise decreased reaction

    Background Fever is common among patients seeking care in sub-Saharan Africa (sSA), but causes other than malaria are rarely diagnosed. We assessed dengue and chikungunya virus infections among young febrile adults evaluated for acute HIV infection (AHI) and malaria in coastal Kenya. Methods We tested plasma samples obtained in a cross-sectional study from febrile adult patients aged 18–35 years evaluated for AHI and malaria at urgent care seeking at seven health facilities in coastal Kenya in 2014–2015. Dengue virus (DENV) and chikungunya virus (CHIKV) were amplified using quantitative real-time reverse-transcription polymerase chain reaction. We conducted logistic regression analyses to determine independent predictors of dengue virus infection. Results 489 samples that were negative for both AHI and malaria were tested, of which 43 (8.8%, 95% confidence interval [CI]: 6.4–11.7) were positive for DENV infection. No participant was positive for CHIKV infection. DENV infections were associated with clinic visits in the rainy season (adjusted odds ratio (AOR) = 3.0, 95% CI: 1.3–6.5) and evaluation at a private health facility (AOR 5.2, 95% CI: 2.0–13.1) or research health facility (AOR = 25.6, 95% CI: 8.9–73.2) instead of a public health facility. Conclusion A high prevalence of DENV infections was found in febrile young adult patients evaluated for AHI. Our data suggests that DENV, along with AHI and malaria, should be considered in the differential diagnosis of the adult patient seeking care for fever in coastal Kenya. PMID:27942016

    In contrast to FLT3 ITD mutations, in-frame deletions in the FLT3 gene have rarely been described in adult acute leukemia. We report two cases of AML with uncommon in-frame mutations in the juxtamembrane domain of the FLT3 gene: a 3-bp (c.1770_1774delCTACGinsGT; p.F590_V592delinsLF) deletion/insertion and a 12-bp (c.1780_1791delTTCAGAGAATAT; p.F594_Y597del) deletion. We verified by sequencing that the reading frame of the FLT3 gene was preserved and by cDNA analysis that the mRNA of the mutant allele was expressed in both cases. Given the recent development of FLT3 inhibitors, our findings may be of therapeutic value for AML patients harboring similar FLT3 mutations. PMID:25379410

    Of 41 adults with a diagnosis of acute leukemia that were randomized for induction therapy in combination with methotrexate, 6-MP, vincristine and prednisone (POMP) versus a combination of cytosine arabinoside, cytoxan, vincristine and prednisone (COAP), 23 (56%) patients achieved a complete remission. During remission, patients received consolidation therapy with the three courses of remission induction regimen that they had not received initially. They then received daunomycin (three courses) and L-asparaginase and were then maintained for two years with their induction therapy. The median duration of survival for all patients was 40 weeks; the median duration of survival of those patients that responded to chemotherapy was 80 weeks. There was no significant difference between the two induction regimens with regard to complete remission more than four and one half years from diagnosis and two and one half years from discontinuation of all therapy.

    The therapeutic regimens for acute myelogenous leukemia in 2 different periods of time will be described with comparison of their results. A. 28 adults were treated with cytosine arabinoside and 6-thioguanine only. Thereby, 28% complete and 16% partial remissions were achieved. The mean duration of the complete remissions was 23 weeks. The mean survival time of the patients with complete remission amounted to 53 weeks B. 46% complete and 12% partial remissions were obtained in 37 patients treated with cytosine arabinoside and 6-thioguanine doubling the dosage of the above mentioned regimen followed by 3 cycles of TRAP (and COAP). Using a maintenance therapy with modified TRAP, COAP, and POMP cycles the complete remissions lasted 47 weeks at an average. The mean survival time of patients with complete remission was 87 weeks after start of treatment.

    A 45-year-old hypertensive Japanese woman presented with epigastric pain on inspiration, fever, complete atrioventricular block and polyarthritis. Her antistreptolysin O levels were markedly elevated. A diagnosis of rheumatic fever was made according to the modified Jones criteria. She was prescribed loxoprofen sodium, which was partially effective for her extracardiac clinical symptoms. However, she had syncope due to complete atrioventricular block with asystole longer than 10 seconds. Consequently, we implanted a permanent pacemaker. Although we prescribed prednisolone, the efficacy of which was limited for the patient's conduction disturbance, the complete atrioventricular block persisted. In our systematic review of 12 similar cases, the duration of complete heart block was always transient and there was no case requiring a permanent pacemaker. We thus encountered a very rare case of adult-onset acute rheumatic fever with persistent complete atrioventricular block necessitating permanent pacemaker implantation.

    Pulmonary involvement in the form of acute pneumonitis in adult-onset Still's disease (AOSD) is an uncommon manifestation, with few cases reported in the literature. We report the case of a 61-year-old male with 3 years of AOSD evolution, treated with methotrexate (MTX) and half-dose corticosteroids, which debuted with symptoms of fever, dyspnea and dry cough after 3 weeks of receiving the first dose of tocilizumab (TCZ). In the follow-up study showed leukocytosis with left shift, elevated serum ferritin and C-reactive protein standard. The chest CT scan showed ground-glass pattern predominantly in central and upper lobes and the BAL shows an increase in the percentage of lymphocyte with normal subpopulations and negative cultures. MTX and TCM were suspended, prednisone was increased to 30mg/day and within a week Anakinra 100mg/day SC was iniciated, noting in a few days a progressive clinical, analytical and radiological improvement.

    Acute stress is increasingly recognized as a precipitant of acute myocardial infarction (AMI). However, the role of chronic stress in developing AMI is less clear. We have developed a method to measure cortisol in hair, which allows longitudinal assessment of cortisol levels prior to an acute event. We aimed to evaluate the hypothesis that chronic stress, as assessed by hair cortisol content, is associated with the development of AMI. A prospective case-control study included 56 patients admitted to hospital with AMI and 56 control patients, admitted to internal medicine wards for other indications. An enzyme immunoassay technique was used to measure cortisol in the most proximal 3 cm of hair, considered to represent the most recent 3 months of exposure. Median hair cortisol contents (range) were 295.3 (105.4-809.3)ng/g in AMI patients and 224.9 (76.58-949.9)ng/g in controls (p = 0.006, Mann-Whitney U-test). After controlling for other risk factors for AMI using multiple logistic regression, log-transformed hair cortisol content remained the strongest predictor (OR 17.4, 95% CI 2.15-140.5; p = 0.007). We demonstrated elevated hair cortisol concentrations in patients with AMI. This suggests that chronic stress, as assessed by increased hair cortisol in the 3 months prior to the event, may be a contributing factor for AMI.

    At times, total dissolved gas concentrations in the Columbia and Snake rivers have been elevated due to involuntary spill from high spring runoff and voluntary spill used as a method to pass juvenile salmonids over dams. The goal of this project was to determine if acute exposure to total dissolved gas supersaturation (TDGS) affects the reproductive performance of female chinook salmon late in their maturation. During this study, adult female spring chinook salmon were exposed to mean TDGS levels of 114.1 % to 125.5%. We ended exposures at first mortality, or at the appearance of impending death. Based on this criterion, exposures lasted from 10 to 68 h and were inversely related to TDGS. There was no effect of TDGS on pre-spawning mortality or fecundity when comparing treatment fish to experimental controls or the general hatchery population four to six weeks after exposures. Egg quality, based on egg weight and egg diameter, did not differ between treatment and control fish. Fertilization rate and survival to eyed-stage was high (>94%) for all groups. With the exception of Renibacterium salmoninarum (the causative agent of bacterial kidney disease; BKD), no viral or bacterial fish pathogens were isolated from experimental fish. The prevalence (about 45%) and severity of R. salmoninarum did not differ among the groups or the general hatchery population. We conclude that these acute exposures to moderate levels of gas-supersaturated water-perhaps similar to that experienced by immigrating adult salmon as they approach and pass a hydropower dam on the Columbia River-did not affect reproductive success of female chinook salmon late in their maturation. These results are most applicable to summer and fall chinook salmon, which migrate in the summer/fall and spawn shortly after reaching their natal streams.

    A significant proportion of patients discharged from the emergency department (ED) with asthma exacerbations will relapse within 4 weeks. This systematic review summarises the evidence regarding relapses and factors associated with relapse in adult patients discharged from EDs after being treated for acute asthma. Following a registered protocol, comprehensive literature searches were conducted. Studies tracking outcomes for adults after ED management and discharge were included if they involved adjusted analyses. Methodological quality was assessed using the Newcastle–Ottawa Scale (NOS) and the Risk of Bias (RoB) Tool. Results were summarised using medians and IQRs or mean and SD, as appropriate. 178 articles underwent full-text review and 10 studies, of various methodologies, involving 32 923 patients were included. The majority of the studies were of high quality according to NOS and RoB Tool. Relapse proportions were 8±3%, 12±4% and 14±6% at 1, 2 and 4 weeks, respectively. Female sex was the most commonly reported and statistically significant factor associated with an increased risk of relapse within 4 weeks of ED discharge for acute asthma. Other factors significantly associated with relapse were past healthcare usage and previous inhaled corticosteroids (ICS) usage. A median of 17% of patients who are discharged from the ED will relapse within the first 4 weeks. Factors such as female sex, past healthcare usage and ICS use at presentation were commonly and significantly associated with relapse occurrence. Identifying patients with these features could provide clinicians with guidance during their ED discharge decision-making. PMID:28176972

    The negative feedback mechanism through which 17β-estradiol (E2) acts to suppress the activity of the GnRH neurons remains unclear. Using inducible and cell-specific genetic mouse models, we examined the estrogen receptor (ER) isoforms expressed by neurons that mediate acute estrogen negative feedback. Adult female mutant mice in which ERα was deleted from all neurons in the neonatal period failed to exhibit estrous cycles or negative feedback. Adult mutant female mice with neonatal neuronal ERβ deletion exhibited normal estrous cycles, but a failure of E2 to suppress LH secretion was seen in ovariectomized mice. Mutant mice with a GnRH neuron-selective deletion of ERβ exhibited normal cycles and negative feedback, suggesting no critical role for ERβ in GnRH neurons in acute negative feedback. To examine the adult roles of neurons expressing ERα, an inducible tamoxifen-based Cre-LoxP approach was used to ablate ERα from neurons that express calmodulin kinase IIα in adults. This resulted in mice with no estrous cycles, a normal increase in LH after ovariectomy, but an inability of E2 to suppress LH secretion. Finally, acute administration of ERα- and ERβ-selective agonists to adult ovariectomized wild-type mice revealed that activation of ERα suppressed LH secretion, whereas ERβ agonists had no effect. This study highlights the differences in adult reproductive phenotypes that result from neonatal vs adult ablation of ERα in the brain. Together, these experiments expand previous global knockout studies by demonstrating that neurons expressing ERα are essential and probably sufficient for the acute estrogen negative feedback mechanism in female mice.

    Background Acute bacterial meningitis is a medical emergency condition that requires prompt diagnosis and treatment and otherwise associated with serious morbidity and mortality. Aim The aim of this study was to assess types, risk factors, clinical symptoms and diagnostic tests of meningitis in hospitalized patients of Mazandaran University of medical sciences hospitals during 2006-2012. Matherials and Methods This is a retrospective descriptive study. Following approval of the ethics committee of Mazandaran University of Medical Sciences, records of adult patients diagnosed with acute meningitis from 2006 to 2012 were extracted from Mazandaran Provincial Health Center and patients attending hospitals affiliated to Mazandaran University of Medical Sciences. Statistical Analysis Data were analyzed with SPSS-16 using descriptive statistics (frequency, mean, standard deviation, and median). Results In this study, of the 137 patients with meningitis, 73 (53.9%) were viral, 61 (46%) bacterial, 1 (0.7%) fungal, and 2 (1.4%) unknown. The majority of risk factors in patients were head trauma, upper respiratory infection, and drug addiction. The most common clinical signs were headache, fever, nausea and vomiting, and stiff neck. Conclusion In this study, the incidence of meningitis was much lower than any other country. It could be due to geographic variation or incomplete recording of patient's data. It is recommended to perform a longitudinal study during the coming years on patients with meningitis. PMID:26155497

    Recent advances in molecular diagnostics have allowed us to recognize Human caliciviruses (HuCVs) as important agents of acute diarrhea in industrialized countries. Their prevalence and genetic diversity in developing countries remains unknown. We report on the characterization of HuCVs among adults presenting acute diarrheas in Djibouti; 108 stool samples collected were screened by EIA, RTPCR, or cell cultures for the group A Rotaviruses, Adenoviruses, Astroviruses, and HuCVs, which were further characterized by genotyping. Among stool samples screened for HuCVs, 25.3% were positive. The other enteric viruses were less prevalent. The 11 HuCV strains sequenced revealed a large diversity (3 sapoviruses and 8 noroviruses). GII strains noroviruses were predominant, five were newly described genotypes, and two were recombinant with a pol gene related to GGIIb strains with the particularity to associate a unique pol gene to different capsid genes. These results could help to the knowledge of HuCV infections in Tropical Africa.

    The study goals were to (1) establish the variability in postprandial glucose control in healthy young people consuming a mixed meal and, then (2) determine the acute and residual impact of a single exercise bout on postprandial glucose control. In study 1, 18 people completed two similar mixed meal trials and an intravenous glucose tolerance test (IVGTT). There were strong test-retest correlations for the post-meal area under the curve (AUC) for glucose, insulin, and Cpeptide (r = 0.73–0.83) and the Matsuda insulin sensitivity index (ISI, r = 0.76), and between meal and IVGTT-derived ISI (r = 0.83). In study 2, 11 untrained young adults completed 3 trials. One trial (No Ex) was completed after refraining from vigorous activity for ≥3 days. On the other 2 trials, a 45-min aerobic exercise bout was performed either 17-hours (Prior Day Ex) or 1-hour (Same Day Ex) before consuming the test meal. Compared to No Ex and Prior Day Ex, which did not differ from one another, there were lower AUCs on the Same Day Ex trial for glucose (6%), insulin (20%) and C-peptide (14%). Thus, a single moderate intensity exercise session can acutely improve glycemic control but the effect is modest and short-lived. PMID:22666560

    Bats are increasingly being recognized as important reservoir hosts for a large number of viruses, some of them can be highly virulent when they infect human and livestock animals. Among the new bat zoonotic viruses discovered in recent years, several reoviruses (respiratory enteric orphan viruses) were found to be able to cause acute respiratory infections in humans, which included Melaka and Kampar viruses discovered in Malaysia, all of them belong to the genus Orthoreovirus, family Reoviridae. In this report, we describe the isolation of a highly related virus from an adult patient who suffered acute respiratory illness in Malaysia. Although there was no direct evidence of bat origin, epidemiological study indicated the potential exposure of the patient to bats before the onset of disease. The current study further demonstrates that spillover events of different strains of related orthoreoviruses from bats to humans are occurring on a regular basis, which calls for more intensive and systematic surveillances to fully assess the true public health impact of these newly discovered bat-borne zoonotic reoviruses.

    Sex variation has been persistently investigated in studies concerning acute myeloid leukemia (AML) survival outcomes but has not been fully explored among pediatric and young adult AML patients. We detected sex difference in the survival of AML patients diagnosed at ages 0-24 years and explored distinct effects of sex across subgroups of age at diagnosis, race-ethnicity and AML subtypes utilizing the United States Surveillance Epidemiology and End Results (SEER) population based dataset of 4865 patients diagnosed with AML between 1973 and 2012. Kaplan-Meier survival function, propensity scores and stratified Cox proportional hazards regression were used for data analyses. After controlling for other prognostic factors, females showed a significant survival advantage over their male counterparts, adjusted hazard ratio (aHR, 95% confidence interval (CI): 1.09, 1.00-1.18). Compared to females, male patients had substantially increased risk of mortality in the following subgroups of: ages 20-24 years at diagnosis (aHR1.30), Caucasian (1.14), acute promyelocytic leukemia (APL) (1.35), acute erythroid leukemia (AEL) (1.39), AML with inv(16)(p13.1q22) (2.57), AML with minimum differentiation (1.47); and had substantially decreased aHR in AML t(9;11)(p22;q23) (0.57) and AML with maturation (0.82). Overall, females demonstrated increased survival over males and this disparity was considerably large in patients ages 20-24 years at diagnosis, Caucasians, and in AML subtypes of AML inv(16), APL and AEL. In contrast, males with AML t(9;11)(p22;q23), AML with maturation and age at diagnosis of 10-14 years showed survival benefit. Further investigations are needed to detect the biological processes influencing the mechanisms of these interactions.

    OBJECTIVE--To ascertain the standard of care for hospital management of acute severe asthma in adults. DESIGN--Questionnaire based retrospective multicentre survey of case records. SETTING--36 hospitals (12 teaching and 24 district general hospitals) across England, Wales, and Scotland. PATIENTS--All patients admitted with acute severe asthma between 1 August and 30 September 1990 immediately before publication of national guidelines for asthma management. MAIN MEASURES--Main recommendations of guidelines for hospital management of acute severe asthma as performed by respiratory and non-respiratory physicians. RESULTS--766 patients (median age 41 (range 16-94) years) were studied; 465 (63%) were female and 448 (61%) had had previous admissions for asthma. Deficiencies were evident for each aspect of care studied, and respiratory physicians performed better than non-respiratory physicians. 429 (56%) patients had had their treatment increased in the two weeks preceding the admission but only 237 (31%) were prescribed oral steroids. Initially 661/766 (86%) patients had peak expiratory flow measured and recorded but only 534 (70%) ever had arterial blood gas tensions assessed. 65 (8%) patients received no steroid treatment in the first 24 hours after admission. Variability of peak expiratory flow was measured before discharge in 597/759 (78%) patients, of whom 334 (56%) achieved good control (variability < 25%). 47 (6%) patients were discharged without oral or inhaled steroids; 182/743 (24%) had no planned outpatient follow up and 114 failed to attend, leaving 447 (60%) seen in clinic within two months. Only 57/629 (8%) patients were recorded as having a written management plan. CONCLUSIONS--The hospital management of a significant minority of patients deviates from recommended national standards and some deviations are potentially serious. Overall, respiratory physicians provide significantly better care than non-respiratory physicians. PMID:10142032

    The present work aimed to investigate the effects of acute sucrose treatment on the perception of painful stimuli. Specifically, we sought to determine the involvement of the endogenous opioid peptide-mediated system as well as the role of the μ(1)-opioid receptor in antinociception organisation induced by acute sucrose intake. Nociception was assessed with the tail-flick test in rats (75, 150 and 250 g) of different ages acutely pre-treated with 500 μL of a sucrose solution (25, 50, 150 and 250 g/L) or tap water. Young and Adult rats (250 g) showed antinociception after treatment with 50 g/L (during 5 min) and 150 g/L and 250 g/L (during 20 min) sucrose solutions. Surprisingly, this antinociception was more consistent in mature adult rodents than in pups. To evaluate the role of opioid systems, mature adult rodents were pre-treated with different doses (0.25, 1 or 4 mg/kg) of the non-selective opioid receptor antagonist naloxone, the selective μ(1)-opioid receptor antagonist naloxonazine or vehicle followed by 250 g/L sucrose solution treatment. Sucrose-induced antinociception was reduced by pre-treatment with both naloxone and naloxonazine. The present findings suggest that sweet substance-induced hypo-analgesia is augmented by increasing sucrose concentrations in young and adult rodents. Acute oral sucrose treatment inhibits pain in laboratory animal by mediating endogenous opioid peptide and μ(1)-opioid receptor actions.

    The survival rates for both adult and children with acute lymphoblastic leukaemia have improved substantially in recent years with wider use of improved risk-directed therapy and supportive care. In nearly all developed countries, clinical practice guidelines have been formulated by multidisciplinary panels of leukaemia experts, with the goal of providing recommendations on standard treatment approaches based on current evidence. However, those guidelines do not take into account resource limitations in low-income countries, including financial and technical challenges. In Asia, there are huge disparities in economy and infrastructure among the countries, and even among different regions in some large countries. This review summarizes the recommendations developed for Asian countries by a panel of adult and paediatric leukaemia therapists, based on the availability of financial, skill and logistical resources, at a consensus session held as part of the 2013 Asian Oncology Summit in Bangkok, Thailand. The management strategies described here are stratified by a four-tier system (basic, limited, enhanced and maximum) based on the resources available to a particular country or region. PMID:24176570

    Objectives. Overview the quality, direction, and characteristics of yoga interventions for treatment of acute and chronic health conditions in adult populations. Methods. We searched for systematic reviews in 10 online databases, bibliographic references, and hand-searches in yoga-related journals. Included reviews satisfy Oxman criteria and specify yoga as a primary intervention in one or more randomized controlled trials for treatment in adults. The AMSTAR tool and GRADE approach evaluated the methodological quality of reviews and quality of evidence. Results. We identified 2202 titles, of which 41 full-text articles were assessed for eligibility and 26 systematic reviews satisfied inclusion criteria. Thirteen systematic reviews include quantitative data and six papers include meta-analysis. The quality of evidence is generally low. Sixteen different types of health conditions are included. Eleven reviews show tendency towards positive effects of yoga intervention, 15 reviews report unclear results, and no, reviews report adverse effects of yoga. Yoga appears most effective for reducing symptoms in anxiety, depression, and pain. Conclusion. Although the quality of systematic reviews is high, the quality of supporting evidence is low. Significant heterogeneity and variability in reporting interventions by type of yoga, settings, and population characteristics limit the generalizability of results.

    While a number of studies have established that moderate doses of alcohol increase brain perfusion, the time course of such an increase as a function of breath alcohol concentration (BrAC) has not yet been investigated, and studies differ about regional effects. Using arterial spin labeling (ASL) magnetic resonance imaging, we investigated (1) the time course of the perfusion increase during a 15-minute linear increase of BrAC up to 0.6 g/kg followed by a steady exposure of 100 minutes, (2) the regional distribution, (3) a potential gender effect, and (4) the temporal stability of perfusion effects. In 48 young adults who participated in the Dresden longitudinal study on alcohol effects in young adults, we observed (1) a 7% increase of global perfusion as compared with placebo and that perfusion and BrAC are tightly coupled in time, (2) that the increase reaches significance in most regions of the brain, (3) that the effect is stronger in women than in men, and (4) that an acute tolerance effect is not observable on the time scale of 2 hours. Larger studies are needed to investigate the origin and the consequences of the effect, as well as the correlates of inter-subject variations.

    The use of extracorporeal membrane oxygenation (ECMO) for severe acute respiratory failure (ARF) in adults is growing rapidly given recent advances in technology, even though there is controversy regarding the evidence justifying its use. Because ECMO is a complex, high-risk, and costly modality, at present it should be conducted in centers with sufficient experience, volume, and expertise to ensure it is used safely. This position paper represents the consensus opinion of an international group of physicians and associated health-care workers who have expertise in therapeutic modalities used in the treatment of patients with severe ARF, with a focus on ECMO. The aim of this paper is to provide physicians, ECMO center directors and coordinators, hospital directors, health-care organizations, and regional, national, and international policy makers a description of the optimal approach to organizing ECMO programs for ARF in adult patients. Importantly, this will help ensure that ECMO is delivered safely and proficiently, such that future observational and randomized clinical trials assessing this technique may be performed by experienced centers under homogeneous and optimal conditions. Given the need for further evidence, we encourage restraint in the widespread use of ECMO until we have a better appreciation for both the potential clinical applications and the optimal techniques for performing ECMO.

    Acute myeloid leukemia (non APL) is a group of highly heterogeneous hematologic malignancy.In recent years, after the standard "3+7" regimen, the complete remission rate of adult patients with AML (non-APL) can be as high as 70%-80%. However, due to the existence of minimal residual disease after remission, the recurrence of the disease still inevitable, only approximately 20% to 30% of the patients enjoy longterm disease-free survival. Currently only allogeneic hematopoietic stem cell transplantation is one of the most effective treatment ways for AML. The number of transplant patients is limited, because of various reasons, such as the physical condition of patients, donor sources or economic reason. After transplantation, patients also have the possibility of recurrence, therefore, drug treatment is still important after AML remission. At present, NCCN (National Comprehensive Cancer Network) recommended high-dose cytarabine as first-line postremission therapy for patients of good prognosis group and as second-line therapy for intermediate risk group. In recent years, researchers have explored other drugs, such as the nucleoside analogues, methyltransferase inhibitors and protease inhibitors or other drugs for the treatment of adult AML patients who is in remission.In this article, the treatment of conventional medicine for the treatment of AML after complete remission is summarized.

    The role of serum cystatin C (Scys) for the detection of acute kidney injury (AKI) has not been fully discussed. This meta-analysis was aimed to investigate the overall diagnostic accuracy of Scys for AKI in adults, and further identify factors affecting its performance. Studies before Sept. 2016 were retrieved from PubMed, Embase, Web of Science and the Cochrane Library. A total of 30 prospective cohort studies (involving 4247 adults from 15 countries, 982 patients occurring AKI) were included. The revised Quality Assessment for Studies of Diagnostic Accuracy (QUADAS-2) tools demonstrated no significant bias had influenced the methodological quality of the included studies. Scys showed a high predictive power for all-cause AKI, that the area under the receiver operating characteristic curve was 0.89. The detailed assessment parameters, such as sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio for Scys were 0.82, 0.82, 4.6, 0.22 and 21, respectively. Although Scys could be slightly influenced by the following factors: settings, AKI diagnostic criteria, ethnicity, determination method, age and gender, these factors above did not reach statistically significance. In conclusion, Scys could be a vital promising marker to screen out AKI. PMID:28112204

    Human rhinovirus (HRV) is an important causative agent of acute respiratory tract infections (ARTIs). The roles of specific HRV genotypes in patients suffering from ARTIs have not been well established. We recruited 147 adult inpatients with community-acquired pneumonia (CAP) and 291 adult outpatients with upper ARTIs (URTIs). Respiratory pathogens were screened via PCR assays. HRV was detected in 42 patients, with 35 species A, five B and two C. Seventeen genotypes were identified, and HRV-A21 ranked the highest (9/42, 21.4%). The HRV-A21-positive infections were detected in four patients with CAP and in five with URTIs, all without co-infections. The HRV-A21 genome sequenced in this study contained 12 novel coding polymorphisms in viral protein (VP) 1, VP2 EF loop, VP3 knob and 3D regions. The infections of HRV-A21 virus obtained in this study could not be neutralized by antiserum of HRV-A21 prototype strain (VR-1131), indicating remarkable antigenic variation. Metagenomic analysis showed the HRV-A21 reads were dominant in bronchoalveolar lavage fluid of the three HRV-A21-positive patients with severe CAP, in which two dead. Our results highlight an unexpected infection of genotype HRV-A21 in the clinic, indicating the necessity of precise genotyping and surveillance of HRVs to improve the clinical management of ARTIs.

    T-cell acute lymphoblastic leukemia (T-ALL) results from the collaboration of multiple genetic abnormalities in the transformation of T-cell progenitors. Plant homeodomain finger protein 6 (PHF6) has recently been established as a key tumor suppressor, which is mutated in T-ALL; however, the clinical significance of PHF6 mutations has not been fully determined in adult T-ALL. In the present study, amplification of the PHF6 exons was performed, followed by DNA sequencing to identify the genomic mutations and examine the expression of PHF6 in adult patients with T-ALL. The correlation between PHF6 mutations and clinical features was also analyzed using a χ2 test, and between PHF6 mutations and survival curve using the Kaplan-Meier methods. PHF6 mutations were detected in 27.1% of the Chinese adults with T-ALL (16/59), 10 of which were found to be novel mutations. A significantly lower expression level of PHF6 was observed in T-ALL patients with PHF6 mutations compared with those without mutations. Of the observed mutations in PHF6, 6/16 were frame-shift mutations, indicating a PHF6 dysfunction in those patients. Of note, PHF6 mutations were found to be significantly associated with older age, lower hemoglobin levels, higher frequency of CD13 positivity and higher incidence of splenomegaly or lymphadenopathy. Furthermore, PHF6 mutations were found to be significantly correlated with Notch homolog 1, translocation-associated (Drosophila) (NOTCH1) mutations. The patients with T-ALL with co-existence of the two mutations had a significantly shorter event-free survival and a poor prognosis. The present results indicated that PHF6 is inactivated in adult T-ALL, due to its low expression and mutations. The present data indicated the synergistic effect of PHF6 and NOTCH1 mutations, as well as their co-existence, on the oncogenesis of adult T-ALL, and their potential as a prognostic marker for the disease.

    The cognitive reserve is the capacity of the brain to maintain normal performance while exposed to insults or ageing. Increasing evidences point to a role for the interaction between inflammatory conditions and cognitive reserve status during Alzheimer's disease (AD) progression. The production of new neurons along adult life can be considered as one of the components of the cognitive reserve. Interestingly, adult neurogenesis is decreased in mouse models of AD and following inflammatory processes. The aim of this work is to reveal the long-term impact of a systemic inflammatory event on memory and adult neurogenesis in wild type (WT) and triple transgenic mouse model of AD (3xTg-AD). Four month-old mice were intraperitoneally injected once with saline or lipopolysaccharide (LPS) and their performance on spatial memory analyzed with the Morris water maze (MWM) test 7 weeks later. Our data showed that a single intraperitoneal injection with LPS has a long-term impact in the production of hippocampal neurons. Consistently, LPS-treated WT mice showed less doublecortin-positive neurons, less synaptic contacts in newborn neurons, and decreased dendritic volume and complexity. These surprising observations were accompanied with memory deficits. 3xTg-AD mice showed a decrease in new neurons in the dentate gyrus compatible with, although exacerbated, the pattern observed in WT LPS-treated mice. In 3xTg-AD mice, LPS injection did not significantly affected the production of new neurons but reduced their number of synaptic puncta and impaired memory performance, when compared to the observations made in saline-treated 3xTg-AD mice. These data indicate that LPS treatment induces a long-term impairment on hippocampal neurogenesis and memory. Our results show that acute neuroinflammatory events influence the production of new hippocampal neurons, affecting the cognitive reserve and leading to the development of memory deficits associated to AD pathology.

    Background: For adult ALL patients, the indications and appropriate timing of allogeneic hematopoietic stem cell transplantation (AHSCT) continue to be debated. The primary aim of this single-institution study was to compare the results of our adult ALL patients that had been allografted with those reported in the current literature. Subjects and Methods: This study included 53 consecutive adults with acute lymphoblastic leukemia (ALL) who underwent allogeneic hematopoietic stem cell transplantation (AHSCT) with myeloablative (92%) and reduced-intensity (8%) conditioning between 1993 and 2011. Results: Mean patient age was 27 years (SD:8.62) and donor age was 33.7 years (SD:9.47). Fourteen patients were in first remission; 21 in ≥2nd remission, 15 in relapse and 3 had primary refractory leukemia. Thirty-four, 15 and 4 patients received busulfan plus cyclophosphamide, cyclophosphamide/total body irradiation and fludarabine-based regimens, respectively. For graft-versus-host disease (GVHD) prophylaxis, cyclosporine plus methotrexate were used. Forty-six donors were related and 7 were unrelated. Thirty patients received granulocyte-colony stimulating factor (G-CSF) mobilized peripheral blood and 23 received bone marrow as stem cell source. Twenty-six patients relapsed at a mean duration of 11.3 months (SD:19.1). Forty-four patients succumbed to their disease after a mean follow-up of 13.6 months (SD:19.5). The cause of mortality was relapse (n=24; 54.5%) and transplant-related etiologies (n=20; 45.5%). The estimated five year probabilities of overall survival (OS) and progression-free survival (PFS) were 37% and 12%, respectively. Conclusion: By multivariate analyses, transplantation in first remission was the most important predictor of transplant success. PMID:28286617

    In this study, we randomly compared high doses of the tyrosine kinase inhibitor imatinib combined with reduced-intensity chemotherapy (arm A) to standard imatinib/hyperCVAD (cyclophosphamide/vincristine/doxorubicin/dexamethasone) therapy (arm B) in 268 adults (median age, 47 years) with Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL). The primary objective was the major molecular response (MMolR) rate after cycle 2, patients being then eligible for allogeneic stem cell transplantation (SCT) if they had a donor, or autologous SCT if in MMolR and no donor. With fewer induction deaths, the complete remission (CR) rate was higher in arm A than in arm B (98% vs 91%; P = .006), whereas the MMolR rate was similar in both arms (66% vs 64%). With a median follow-up of 4.8 years, 5-year event-free survival and overall survival (OS) rates were estimated at 37.1% and 45.6%, respectively, without difference between the arms. Allogeneic transplantation was associated with a significant benefit in relapse-free survival (hazard ratio [HR], 0.69; P = .036) and OS (HR, 0.64; P = .02), with initial white blood cell count being the only factor significantly interacting with this SCT effect. In patients achieving MMolR, outcome was similar after autologous and allogeneic transplantation. This study validates an induction regimen combining reduced-intensity chemotherapy and imatinib in Ph+ ALL adult patients and suggests that SCT in first CR is still a good option for Ph+ ALL adult patients. This trial was registered at www.clinicaltrials.gov as #NCT00327678.

    Introduction Poisoning is one of the most important health issues in the world. There is no exact statistic regarding the epidemiology of poisoning in Iran. The aim of this systematic review was to study the epidemiology of poisoning of adults in Iran. Methods All the published papers regarding the epidemiology and patterns of adult poisonings in different parts of Iran were reviewed in bibliographical databases, including SID, Iran Medex, Medlib, Magiran and Embase, Scopus, PubMed, and Google Scholar, without time limitation up to March 21, 2016. We searched for the terms poisoning, Iran, and epidemiology. After the final analysis, 38 articles that fulfilled all the required conditions were selected. Result In this article, we show that in most Iranian cities, except Ahvaz, pharmaceutical drugs, especially psychiatric pharmaceutical drugs, are the most common cause of poisoning in adults. In the Southwest region of Iran, poisoning due to envenomation is a very common. Although pesticide and opioid poisonings are less common, they are an important cause of death due to poisoning in Iran. Conclusion Pharmaceutical drugs are the most common cause of poisoning in most Iranian cities and it is recommended not to store pharmaceutical drugs at home and to set special rules regarding proper description of pharmaceutical drugs. More public health instruction is essential in the Southwest cities of Iran in order to reduce animal poisonings. PMID:27790337

We present a case of a 19-year old female with progressive muscle weakness was admitted in intensive care unit (ICU) with respiratory failure and acute renal failure. Patient was unconscious. Pupils were anisocoric and light reflex was absent. She had hepatomegaly. The laboratory results showed a glucose level of 70 mg/dl and the liver enzymes were high. The patient also had hyponatremia (117 mEq/L) and lactate level of 3.9 mmol/L. Tandem MS and organic acid analysis were compatible with GTA type II. Carnitine 1gr, riboflavin 100 mg and co-enzymeQ10 100 mg was arranged. After four months from beginning of treatment tandem MS results are improved. Respiratory failure, acute renal failure due to profound proximal myopathy can be due to glutaric aciduria type II that responded rapidly to appropriate therapy. PMID:26236614

    Myocarditis consists of an inflammation of the cardiac muscle, definitively diagnosed by endomyocardial biopsy. The causal agents are primarily infectious: in developed countries, viruses appear to be the main cause, whereas in developing countries rheumatic carditis, Chagas disease, and HIV are frequent causes. Furthermore, myocarditis can be indirectly induced by an infectious agent and occurs following a latency period during which antibodies are created. Typically, myocarditis observed in rheumatic fever related to group A streptococcal (GAS) infection occurs after 2- to 3-week period of latency. In other instances, myocarditis can occur within few days following a streptococcal infection; thus, it does not fit the criteria for rheumatic fever. Myocarditis classically presents as acute heart failure, and can also be manifested by tachyarrhythmia or chest pain. Likewise, GAS-related myocarditis reportedly mimics myocardial infarction (MI) with typical chest pain, electrocardiograph changes, and troponin elevation. Here we describe a case of recurrent myocarditis, 5 years apart, with clinical presentation imitating an acute MI in an otherwise healthy 37-year-old man. Both episodes occurred 3 days after GAS pharyngitis and resolved quickly following medical treatment. PMID:24963417

    Recent major advances in understanding the molecular basis of acute myeloid leukemia (AML) provide a double-edged sword. Although defining the topology and key features of the molecular landscape are fundamental to development of novel treatment approaches and provide opportunities for greater individualization of therapy, confirmation of the genetic complexity presents a huge challenge to successful translation into routine clinical practice. It is now clear that many genes are recurrently mutated in AML; moreover, individual leukemias harbor multiple mutations and are potentially composed of subclones with differing mutational composition, rendering each patient's AML genetically unique. In order to make sense of the overwhelming mutational data and capitalize on this clinically, it is important to identify (1) critical AML-defining molecular abnormalities that distinguish biological disease entities; (2) mutations, typically arising in subclones, that may influence prognosis but are unlikely to be ideal therapeutic targets; (3) mutations associated with preleukemic clones; and (4) mutations that have been robustly shown to confer independent prognostic information or are therapeutically relevant. The reward of identifying AML-defining molecular lesions present in all leukemic populations (including subclones) has been exemplified by acute promyelocytic leukemia, where successful targeting of the underlying PML-RARα oncoprotein has eliminated the need for chemotherapy for disease cure. Despite the molecular heterogeneity and recognizing that treatment options for other forms of AML are limited, this review will consider the scope for using novel molecular information to improve diagnosis, identify subsets of patients eligible for targeted therapies, refine outcome prediction, and track treatment response.

    This study was designed to perform an acceptable prognostic nomogram for acute myeloid leukemia. The clinical data from 311 patients from our institution and 165 patients generated with Cancer Genome Atlas Research Network were reviewed. A prognostic nomogram was designed according to the Cox's proportional hazard model to predict overall survival (OS). To compare the capacity of the nomogram with that of the current prognostic system, the concordance index (C-index) was used to validate the accuracy as well as the calibration curve. The nomogram included 6 valuable variables: age, risk stratifications based on cytogenetic abnormalities, status of FLT3-ITD mutation, status of NPM1 mutation, expression of CD34, and expression of HLA-DR. The C-indexes were 0.71 and 0.68 in the primary and validation cohort respectively, which were superior to the predictive capacity of the current prognostic systems in both cohorts. The nomogram allowed both patients with acute myeloid leukemia and physicians to make prediction of OS individually prior to treatment. PMID:27689396

    We present a report of dendritic ulcerative keratitis in a 4-year old locally immunosuppressed dog suspected to result from acute primary canine herpesvirus-1 (CHV-1) infection. The dog was presented for evaluation of mild blepharospasm and conjunctival hyperemia in the right eye (OD) shortly after attending a public boarding facility. For approximately 3 months, the dog had been receiving topical prednisolone acetate 1.0% and tacrolimus 0.02% in both eyes (OU) q12h for treatment of follicular conjunctivitis. Ophthalmic examination revealed three regions of corneal fluorescein retention OD. The lesions had a dendritic pattern, were approximately 2-3 mm in length, and were located at the dorsomedial, lateral, and ventromedial aspects of the cornea. No additional abnormalities were noted on complete ophthalmic and physical examinations. CHV-1 was identified in conjunctival samples OD by polymerase chain reaction, and paired CHV-1 serum virus neutralization antibody titers were positive and consistent with acute infection. Topical prednisolone acetate and tacrolimus were discontinued. The dog was treated with cidofovir 0.5% OU q12h for a period of 4 weeks, with resolution of corneal disease noted within 1 week of treatment. In conjunction with previous studies, this case report supports a central role for alterations in host immune status in the pathogenesis and clinical manifestations of CHV-1 ocular disease in dogs.

    IgM nephropathy is a relatively rare cause of idiopathic nephrotic syndrome.1 It was initially described by van de Putte,2 then by Cohen and Bhasin in 1978, as a distinctive feature of mesangial proliferative glomerulonephritis.2 It is typically characterized by diffuse IgM deposits on the glomeruli and diffuse mesangial hypercellularity. Little is known about the pathogenesis and treatment of this disease.1,3 We describe a patient who presented with nonspecific symptoms of epigastric pain, nausea, and early satiety. Abdominal imaging and endoscopies were unremarkable. She was found to have significant proteinuria (6.4 g/24 hours), hyperlipidemia, and edema consistent with a diagnosis of nephrotic syndrome. Kidney biopsy was performed and confirmed an IgM nephropathy. Less than 2 weeks after her diagnosis of IgM nephropathy, she presented with an acute cerebellar stroke. Thrombophilia is a well-known complication of nephrotic syndrome, but a review of the literature failed to show an association between IgM nephropathy and acute central nervous system thrombosis.

    The dynamics of the antibody response to influenza viruses A (H1N1), A (H3N2) and B, to parainfluenza viruses 1, 2, 3, to adenoviruses and respiratory syncytial virus was studied in paired serum samples collected from 110 patients hospitalized with acute respiratory infections (ARI) and in 40 patients suffering from other diseases. Rises in serum antibody titers to 1--5 of the above mentioned antigens were detected in many of the patients of both groups. The fact is most likely due to the presence of some epidemiologically and clinically uncharacteristic viral ARI (influenza included); simultaneous or successive infections with influenza virus and different other viruses were very frequent. A greater efficiency of the etiological diagnosis of viral ARI can be achieved only by the association of epidemiological and clinical criteria with serological data, the visualization of viral antigens and virus isolation.

  3. Acute behavioral responses to pheromones in C. elegans (adult behaviors: attraction, repulsion).

    The pheromone drop test is a simple and robust behavioral assay to quantify acute avoidance of pheromones in C. elegans, and the suppression of avoidance by attractive pheromones. In the pheromone drop test, water-soluble C. elegans pheromones are individually applied to animals that are freely moving on a large plate. Upon encountering a repellent, each C. elegans animal may or may not try to escape by making a long reversal. The fraction of animals that make a long reversal response indicates the repulsiveness of a given pheromone to a specific genotype/strain of C. elegans. Performing the drop test in the presence of bacterial food enhances the avoidance response to pheromones. Attraction to pheromones can be assayed by the suppression of reversals to repulsive pheromones or by the suppression of the basal reversal rate to buffer.

    Pretreatment assessment of cytogenetic/genetic signature of acute myeloid leukemia (AML) has been consistently shown to play a major prognostic role but also to fail at predicting outcome on individual basis, even in low-risk AML. Therefore, we are in need of further accurate methods to refine the patients' risk allocation process, distinguishing more adequately those who are likely to recur from those who are not. In this view, there is now evidence that the submicroscopic amounts of leukemic cells (called minimal residual disease, MRD), measured during the course of treatment, indicate the quality of response to therapy. Therefore, MRD might serve as an independent, additional biomarker to help to identify patients at higher risk of relapse. Detection of MRD requires the use of highly sensitive ancillary techniques, such as polymerase chain reaction (PCR) and multiparametric flow cytometry(MPFC). In the present manuscript, we will review the current approaches to investigate MRD and its clinical applications in AML management.

    Therapeutic interpersonal relationships are the primary component of all health care interactions that facilitate the development of positive clinician–patient experiences. Therapeutic interpersonal relationships have the capacity to transform and enrich the patients’ experiences. Consequently, with an increasing necessity to focus on patient-centered care, it is imperative for health care professionals to therapeutically engage with patients to improve health-related outcomes. Studies were identified through an electronic search, using the PubMed, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO databases of peer-reviewed research, limited to the English language with search terms developed to reflect therapeutic interpersonal relationships between health care professionals and patients in the acute care setting. This study found that therapeutic listening, responding to patient emotions and unmet needs, and patient centeredness were key characteristics of strategies for improving therapeutic interpersonal relationships.

    This study assessed the relationships between older patients' social support resources and depressive symptoms and psychosocial functioning at 6 months following a psychiatric hospital discharge. The data used in this study were extracted from a prospective study titled "Service Use of Depressed Elders after Acute Care" (National Institute of Mental Health-56208). This sample included 148 older patients who participated in the initial and the 6-month follow-up assessment. Ordinary Least Squares regression (OLS) was used to examine important social support resources in relation to older patients' depressive symptoms and psychosocial functioning. A vast majority of patients were embedded in a social support network that consisted of acquaintances and confidants. Patients' depressive symptoms were related to availability of a confidant and the extent to which they spent time with others. However, patients' psychosocial functioning was not related to social support resources assessed in this study.

    Background The World Health Organization recommends the surveillance of influenza-like illness (ILI) and severe acute respiratory infection (SARI) to respond effectively to both seasonal influenza epidemics and pandemics. In Korea, the “Hospital-based Influenza Morbidity and Mortality (HIMM)” surveillance system has been operated to monitor ILI and SARI occurrences. Materials and Methods A multi-center prospective observational study was conducted. Adult patients with acute respiratory infection (ARI) were enrolled during the 2011-12, 2012-2013, and 2013-2014 influenza seasons at the 10 university hospitals using the HIMM surveillance system. With respect to SARI and pneumonia development, risk profiles were analyzed in patients with ARI in Korea. Results A total of 5,459 cases were eligible for this analysis. Among 5,459 cases with ARI, 2,887 cases (52.9%) were identified that they had influenza infection. Among enrolled cases, 750 cases belonged to the SARI group, while 4,709 cases belonged to the non-SARI group. With respect to pneumonia development, 317 cases were accompanied by pneumonia, and 5,142 cases were not. Multivariate analyses revealed that the following factors were associated with an increased risk of SARI: Old age (≥65 years) (odds ratio [OR] 2.69, 95% confidence interval [CI] 2.2-3.32), chronic heart disease (CHD) (OR 2.24, 95% CI 1.68-2.98), cerebrovascular disease (CVD) (OR 1.49, 95% CI 1.05-2.10), chronic obstructive pulmonary disease (COPD) (OR 2.34, 95% CI 1.48-3.69), asthma (OR 2.33, 95% CI 1.62-3.36), chronic kidney disease (CKD) (OR 2.62, 95% CI 1.73-3.99), chronic liver disease (OR 1.71, 95% CI 1.04-2.81), and autoimmune diseases (OR 2.53, 1.57-4.08). Multivariate analyses revealed that the following factors were independent risk factors for pneumonia development: Old age (≥65 years) (OR 5.71, 95% CI 4.10-7.94), CHD (OR 1.54, 95% CI 1.07-2.22), COPD (OR 2.34, 95% CI 1.48-3.69), asthma (OR 2.33, 95% CI 1.62-3.36), CKD (OR 2.62, 95

    Aim: In this study, we attempted to analyze the impact of insurance based health care system and treatment compliance on the outcome of adolescent and adults with acute lymphoblastic leukemia (ALL). Materials and Methods: Patients who underwent treatment for ALL during the period 2003-2011 were enrolled into this retrospective study. Patients on supportive or palliative care only and patients with age <10 years were excluded. The hospital records and tumor registry records were studied. Patients were stratified into two groups, Group A (prior to the introduction of state health insurance [SHI], 2003-2007) and Group B (after the introduction of SHI, 2008-2011). Overall survival (OS) was calculated using Kaplan–Meier method. Results: A total of 420 patients with suspected or confirmed ALL visited our center during the study period and 179 patients (87 in Group A and 92 in Group B) were considered for inclusion. The median age in years (range) was 18 (10-57) and 18 (10-58) respectively in Groups A and B with males more than females. Median OS (95% CI) was 9 (6.7-11.2) and 12 (7.3-16.7) months in the Groups A and B respectively (P = 0.265). Poor treatment compliance in both groups was high (36% in Group A and 41% in Group B, [P = 0.107]) with lower default rates in Group B (P = 0.019). Patients with good compliance in the total study population and the individual study groups had significantly better OS. Conclusions: Insurance based health care has improved outcomes in the present study but not compliance to treatment. Significantly better OS was observed in patients with good compliance.

    Phosphatidylserine (PS) is an acidic phospholipid that is widely used as an alternative and/or complementary treatment of cognitive impairments. We hypothesize that these changes may be attributable, at least in part, to alterations in hippocampal neurogenesis. The aim of the present study was to investigate the effects of acute and chronic PS administration on hippocampal cell proliferation and survival in adult (5 months old) and middle-aged (12 months old) male Wistar rats. PS was injected daily (50mg/kg, i.p.) during 7 days (acute experiment) or 21 days (chronic experiment). To label newly generated cells, rats received a single BrdU injection (200mg/kg, i.p.) one day before PS treatment. The object recognition test was performed, and the rats were perfused. The brains were removed and processed with immunohistochemistry techniques for Ki-67 (cell proliferation) and BrdU (cell survival). The acute and chronic regimens were unable to promote cognitive improvement in either age group in the object recognition test. The analysis of cell proliferation showed a significant increase in the number of Ki-67-positive cells after acute and chronic PS administration in both age groups. The analysis of cell survival showed that acute and chronic PS administration increased the number of BrdU-positive cells only in adult animals.

    The extracellular superoxide dismutase 3 (SOD3) is highly expressed in both blood vessels and lungs. In different models of pulmonary injury, SOD3 is reduced; however, it is unclear whether this contributes to lung injury. To study the role of acute SOD3 reduction in lung injury, the SOD3 gene was deleted in adult mice by using the Cre-Lox technology. Acute reduction of SOD3 led to a fivefold increase in lung superoxide, marked inflammatory cell infiltration, a threefold increase in the arterial-alveolar gradient, respiratory acidosis, histological changes similar to those observed in adult respiratory distress syndrome, and 85% mortality. Treatment with the SOD mimetic MnTBAP and intranasal administration of SOD-containing polyketal microparticles reduced mortality, prevented the histological alterations, and reduced lung superoxide levels. To understand how mice with the SOD3 embryonic deletion survived without lung injury, gene array analysis was performed. These data demonstrated the up-regulation of 37 genes and down-regulation of nine genes, including those involved in cell signaling, inflammation, and gene transcription in SOD3-/- mice compared with either mice with acute SOD3 reduction or wild-type controls. These studies show that SOD3 is essential for survival in the presence of ambient oxygen and that acute loss of this enzyme can lead to severe lung damage. Strategies either to prevent SOD3 inactivation or to augment its levels might prove useful in the treatment of acute lung injury.

    This study aimed to establish mechanistic links between the aging-associated changes in the functional status of mast cells and the altered responses of mesenteric tissue and mesenteric lymphatic vessels (MLVs) to acute inflammation. We used an in vivo model of acute peritoneal inflammation induced by lipopolysaccharide treatment of adult (9-month) and aged (24-month) F-344 rats. We analyzed contractility of isolated MLVs, mast cell activation, activation of nuclear factor-κB (NF-κB) without and with stabilization of mast cells by cromolyn or blockade of all types of histamine receptors and production of 27 major pro-inflammatory cytokines in adult and aged perilymphatic mesenteric tissues and blood. We found that the reactivity of aged contracting lymphatic vessels to LPS-induced acute inflammation was abolished and that activated mast cells trigger NF-κB signaling in the mesentery through release of histamine. The aging-associated basal activation of mesenteric mast cells limits acute inflammatory NF-κB activation in aged mesentery. We conclude that proper functioning of the mast cell/histamine/NF-κB axis is necessary for reactions of the lymphatic vessels to acute inflammatory stimuli as well as for interaction and trafficking of immune cells near and within the collecting lymphatics.

    Background About one half of adults with acute lymphoblastic leukemia are not cured of the disease and ultimately die. The objective of this study was to explore the factors influencing the outcome of adult patients with relapsed acute lymphoblastic leukemia. Design and Methods We analyzed the characteristics, the outcome and the prognostic factors for survival after first relapse in a series of 263 adult patients with acute lymphoblastic leukemia (excluding those with mature B-cell acute lymphoblastic leukemia) prospectively enrolled in four consecutive risk-adapted PETHEMA trials. Results The median overall survival after relapse was 4.5 months (95% CI, 4–5 months) with a 5-year overall survival of 10% (95% CI, 8%–12%); 45% of patients receiving intensive second-line treatment achieved a second complete remission and 22% (95% CI, 14%–30%) of them remained disease free at 5 years. Factors predicting a good outcome after rescue therapy were age less than 30 years (2-year overall survival of 21% versus 10% for those over 30 years old; P<0.022) and a first remission lasting more than 2 years (2-year overall survival of 36% versus 17% among those with a shorter first remission; P<0.001). Patients under 30 years old whose first complete remission lasted longer than 2 years had a 5-year overall survival of 38% (95% CI, 23%–53%) and a 5-year disease-free survival of 53% (95% CI, 34%–72%). Conclusions The prognosis of adult patients with acute lymphoblastic leukemia who relapse is poor. Those aged less than 30 years with a first complete remission lasting longer than 2 years have reasonable possibilities of becoming long-term survivors while patients over this age or those who relapse early cannot be successfully rescued using the therapies currently available.

    Abstract Rationale: The presence of the Philadelphia chromosome (Ph) in acute lymphoblastic leukemia (ALL) has been associated with a high risk of disease relapse and a poor prognosis. Allogeneic hematopoietic stem cell transplantation (HSCT) is an established treatment for adults with Ph-positive ALL, but relapse remains the primary cause of treatment failure, and is associated with an extremely poor prognosis. The emergence of resistance to tyrosine kinase inhibitors (TKIs) poses a challenge for patients with disease relapses after initial treatment with TKI-containing regimens. Patient concerns: Two patients with TKI-resistant recurrent Ph-positive ALL. Diagnoses: Ph-positive ALL. Interventions: Anti-CD19 CAR T-cell infusion. Outcomes: One patient's bone marrow blasts decreased significantly, and the other reached negative minimal residual disease (MRD). However, we first recorded the development of new-onset acute graft-versus-host disease (aGVHD) after anti-CD19 CAR T-cell infusion in a patient who received allogeneic HSCT. Our 2 case reports also demonstrate the efficacy of anti-CD19 CAR T-cell therapy in the treatment of TKI-resistant Ph-positive ALL. Lessons: Our report suggests that anti-CD19 CAR T-cell therapy may be a promising option for the treatment of relapsed Ph-positive ALL after conventional chemotherapy or allogeneic HSCT. However, caution is due given the possibility of the adverse effects of cytokine release syndrome (CRS)-induced aGVHD for patients receiving allogeneic HSCT. PMID:28002337

    Secondary myelodysplastic syndrome and acute myelogenous leukemia (sMDS/sAML) are the most serious secondary events occurring after immunosuppressive therapy in patients with aplastic anemia. Here we evaluate the outcome of hematopoietic stem cell transplantation (HSCT) in 17 children and young adults with sMDS/sAML after childhood aplastic anemia. The median interval between the diagnosis of aplastic anemia and the development of sMDS/sAML was 2.9 years (range, 1.2 to 13.0 years). At a median age of 13.1 years (range, 4.4 to 26.7 years), patients underwent HSCT with bone marrow (n = 6) or peripheral blood stem cell (n = 11) grafts from HLA-matched sibling donors (n = 2), mismatched family donors (n = 2), or unrelated donors (n = 13). Monosomy 7 was detected in 13 patients. The preparative regimen consisted of busulfan, cyclophosphamide, and melphalan in 11 patients and other agents in 6 patients. All patients achieved neutrophil engraftment. The cumulative incidence of grade II-IV acute graft-versus-host disease (GVHD) was 47%, and that of chronic GVHD was 70%. Relapse occurred in 1 patient. The major cause of death was transplant-related complication (n = 9). Overall survival and event-free survival at 5 years after HSCT were both 41%. In summary, this study indicates that HSCT is a curative therapy for some patients with sMDS/sAML after aplastic anemia. Future efforts should focus on reducing transplantation-related mortality.

    Obesity and its consequences can damage the kidney over time. However, less is known about the impact of developing overweight/obesity during childhood on the kidney in adulthood and the renal impact of a superimposed acute kidney injury (AKI). This study evaluated the effect of obesity induced by a high-fat diet initiated soon after weaning on the adult life of mice and their response to superimposed nephrotoxic effects of cisplatin. C57BL/6 post-weaning mice (3 weeks old) were divided into a control group (CT, n = 12) and a high-fat diet group (HF, n = 12). After 9 weeks, animals were further divided into the following groups: CT, CT treated with a single dose of cisplatin (CTCis, 20 mg/kg, i.p.), HF and HF treated with cisplatin (HFCis). The HF group exhibited higher body weight gain compatible with a moderate obesity. Obese mice presented increased visceral adiposity, hyperkalemia, sodium retention, glomerular hyperfiltration and proteinuria, without any significant changes in blood pressure and glycemia. AKI induced by cisplatin was exacerbated in obese animals with a 92% reduction in the GFR versus a 31% decrease in the CTCis group; this sharp decline resulted in severely elevated serum creatinine and urea levels. Acute tubular necrosis induced by cisplatin was worsened in obese mice. The HFCis group exhibited robust systemic and intrarenal inflammation that was significantly higher than that in the CTCis group; the HFCis group also showed a higher degree of renal oxidative stress. In conclusion, the moderate degree of obesity induced shortly after weaning resulted in mild early renal alterations, however, obese young animals were prone to develop a much more severe AKI induced by cisplatin.

    A 43-year-old female was referred to our hospital for sudden onset of abdominal pain, fullness, and vomiting. Physical examination revealed abdominal distension with mild epigastric tenderness. Abdominal radiography showed massive gastric distension and plain computed tomography (CT) a markedly enlarged stomach filled with gas and fluid. A large volume of gastric contents was suctioned out via a nasogastric (NG) tube. Contrast-enhanced CT showed a grossly distended stomach with displacement of the antrum above the gastroesophageal junction, and the spleen was dislocated inferiorly. Upper gastrointestinal (GI) series showed the greater curvature to be elevated and the gastric fundus to be lower than normal. Acute mesenteroaxial gastric volvulus was diagnosed. GI endoscopy showed a distortion of the gastric anatomy with difficulty intubating the pylorus. Various endoscopic maneuvers were required to reposition the stomach, and the symptoms showed immediate and complete solution. GI fluoroscopy was performed 3 days later. Initially, most of the contrast medium accumulated in the fundus, which was drawn prominently downward, and then began flowing into the duodenum with anteflexion. Elective laparoscopic surgery was performed 1 month later. The stomach was in its normal position, but the fundus was folded posteroinferiorly. The spleen attached to the fundus was normal in size but extremely mobile. We diagnosed a wandering spleen based on the operative findings. Gastropexy was performed for the treatment of gastric volvulus and wandering spleen. The patient remained asymptomatic, and there was no evidence of recurrence during a follow-up period of 24 months. This report describes a rare adult case of acute gastric volvulus associated with wandering spleen. Because delay in treatment can result in lethal complications, it is critical to provide a prompt and correct diagnosis and surgical intervention. We advocate laparoscopic surgery after endoscopic reduction because

    Adult patients with acute leukemia in need of a transplant but without a genoidentical donor are usually considered upfront for transplantation with stem cells from any other allogeneic source, rather than autologous stem cell transplantation. We used data from the European Society for Blood and Marrow Transplantation and performed a matched pair analysis on 188 T-cell-replete haploidentical and 356 autologous transplants done from January 2007 to December 2012, using age, diagnosis, disease status, cytogenetics, and interval from diagnosis to transplant as matching factors. "Haploidentical expert" centers were defined as having reported more than five haploidentical transplants for acute leukemia (median value for the study period). The median follow-up was 28 months. Multivariate analyses, including type of transplant categorized into three classes ("haploidentical regular", "haploidentical expert" and autologous), conditioning intensity (reduced intensity versus myeloablative conditioning) and the random effect taking into account associations related to matching, showed that non-relapse mortality was higher following haploidentical transplants in expert (HR: 4.7; P=0.00004) and regular (HR: 8.98; P<10(-5)) centers. Relapse incidence for haploidentical transplants was lower in expert centers (HR:0.39; P=0.0003) but in regular centers was similar to that for autologous transplants. Leukemia-free survival and overall survival rates were higher following autologous transplantation than haploidentical transplants in regular centers (HR: 1.63; P=0.008 and HR: 2.31; P=0.0002 respectively) but similar to those following haploidentical transplants in expert centers. We conclude that autologous stem cell transplantation should presently be considered as a possible alternative to haploidentical transplantation in regular centers that have not developed a specific expert program.

    Juvenile myelomonocytic leukemia (JMML) is a rare aggressive disease of early childhood. Driver mutations in the Ras signaling pathways are a key feature of JMML patients. Mutations in SETBP1 and JAK3 were recently identified in a subset of JMML patients characterized by poor prognosis and progression of disease. In this study, we report the results of a screening for mutations in SETBP1 and JAK3 of a cohort of seventy Italian patients with JMML, identifying 11.4% of them harboring secondary mutations in these two genes and discovering two new mutations in the SKI domain of SETBP1.JMML xenotransplantation and colony assay provide an initial understanding of the secondary nature of these events occurring in early precursor cells and suggest a different propagating capacity of clones harboring particular mutations.

    Hypomethylating drugs are useful and have been approved for the treatment of myelodysplastic syndromes (MDS) and Chronic Myelomonocytic Leukemia (CMML). However, phase 2 and 3 studies that assessed these agents in MDS, have included only a small number of patients with CMML, and there are just a few specific reports on CMML patients. The Azacitidine is actually authorised for the treatment of CMML patients with 10–29% marrow blasts without myeloproliferative disorder, who are not eligible for haematopoietic stem cell transplantation. This hypomethylating agent in MDS is known for causing transient cytopenias, most often occurring during the first 2 cycles. Here we report a case of an atypical delayed and prolonged hematologic toxicity during Azacitidine treatment in a CMML patient; furthermore we also reviewed the literature regarding the efficacy of the drug and the management of hematologic adverse effects, in term of dose adjustments or alternative schedule of administration, in specific CMML setting.

    The purpose of the Thoracic Society of Australia and New Zealand guidelines is to provide simple, practical evidence-based recommendations for the acute use of oxygen in adults in clinical practice. The intended users are all health professionals responsible for the administration and/or monitoring of oxygen therapy in the management of acute medical patients in the community and hospital settings (excluding perioperative and intensive care patients), those responsible for the training of such health professionals, and both public and private health care organizations that deliver oxygen therapy.

  4. Left Ventricular Responses to Acute Changes in Late Systolic Pressure Augmentation in Older Adults

    PubMed Central

    2013-01-01

    BACKGROUND Changes in the cardiovascular system with age may predispose older persons to development of heart failure with preserved ejection fraction. Vascular stiffening, aortic pressure augmentation, and ventricular–vascular coupling have been implicated. We explored the potential for acute reductions in late systolic pressure augmentation to impact left ventricular relaxation in older persons without heart failure. METHODS Sixteen older persons free of known cardiovascular disease with the exception of hypertension had noninvasive tonometry and cardiac ultrasound to evaluate central augmentation index (AI) and diastolic function at baseline and after randomized, blinded administration of intravenous B-type natriuretic peptide (BNP) and hydralazine in a crossover design. RESULTS AI was significantly reduced after BNP (11.4±8.9 to −0.2±14.7%; P = 0.02) and nonsignificantly reduced after hydralazine (14.7±8.4% to 11.5±8.8%; P = 0.39). With decreased AI during BNP, a trend toward worsened myocardial relaxation by tissue Doppler imaging occurred (E’ velocity pre- and post-BNP: 10.0±2.5 and 8.8±2.0cm/s, respectively; P = 0.06). There was a significant fall in stroke volume with BNP (68.5±18.3 to 60.9±18.1ml; P = 0.02), suggesting that changes in preload overwhelmed effects of afterload reduction on ventricular performance. With hydralazine, neither relaxation nor stroke volume changed. CONCLUSIONS Acute changes in late systolic aortic pressure augmentation do not necessarily lead to improved systolic or diastolic function in older people. Preload may be a more important determinant of cardiac performance than afterload in older people with compensated ventricular function. The potential for changes in preload to impair rather than enhance left ventricular systolic and diastolic function in older people warrants further study.

    Background High serum uric acid (sUA) is an indicator of oxidative stress and is linked to tissue hypoxia in asthma. The objective of this case series was to investigate the prognostic role of sUA in patients with acute asthma exacerbations and the link between sUA and spirometric lung tests. Patients and methods This cross-sectional observational study included 120 patients with acute asthma exacerbations and 120 controls, categorized according to peak expiratory flow rate into moderate, and severe and life-threatening asthma. On admission, a detailed history was obtained and investigations were carried out regarding oxygen saturation (SaO2), arterial blood gas, spirometry, sUA, number of asthma exacerbations, smoking status, history of previous hospitalization, intensive care unit admission, and mechanical ventilation. Results The current study revealed higher sUA in asthmatic patients compared with healthy subjects and in severe asthma patients compared with moderate asthma patients (P<0.001). A positive correlation of sUA with asthma severity, number of asthma exacerbations and smoking index (r=0.6, 0.42 and 0.29, respectively, P<0.001) and a negative correlation of sUA with SaO2, partial pressure of arterial oxygen (PaO2), percent predicted forced vital capacity, percent predicted forced expiratory volume (FEV%) and peak expiratory flow rate percent of predicted (PEFR%; r=−0.48, −0.29, −0.44, −0.44 and −0.66, respectively, P<0.001) were observed. Degree of asthma severity, number of asthma exacerbations, and smoking index were significant predictors of high sUA (R2=0.43, P<0.001) in multiple linear regression model 1. SaO2 and PEFR% were significant predictors of high uric acid (R2=0.50, P<0.001) in model 2. The sensitivity and specificity of sUA in predicting severity of asthma at the cutoff point of 6.3 mg/dL were 80% and 90%, respectively. The odds ratios of sUA, number of asthma exacerbations, and asthma duration were 5.4, 1.95 and 1

    An inverse relation exists between intake of flavonoid-rich foods, such as cocoa, and cardiovascular-related mortality. Favorable effects of flavonoids on the endothelium may underlie these associations. We performed a randomized, double-blind, placebo-controlled study to test the hypothesis that acute cocoa ingestion dose dependently increases endothelium-dependent vasodilation, as measured by an increase in brachial artery flow-mediated dilation (FMD), in healthy older adults. Measurements were obtained before (preingestion) and after (1- and 2-h postingestion) ingestion of 0 (placebo), 2, 5, 13, and 26 g of cocoa in 23 adults (63 ± 2 yr old, mean ± SE). Changes in brachial artery FMD 1- and 2-h postingestion compared with preingestion were used to determine the effects of cocoa. FMD was unchanged 1 (Δ−0.3 ± 0.2%)- and 2-h (Δ0.1 ± 0.1%) after placebo (0 g cocoa). In contrast, FMD increased both 1-h postingestion (2 g cocoa Δ0.0 ± 0.2%, 5 g cocoa Δ0.8 ± 0.3%, 13 g cocoa Δ1.0 ± 0.3%, and 26 g cocoa Δ1.6 ± 0.3%: P < 0.05 compared with placebo for 5, 13, and 26 g cocoa) and 2-h postingestion (2 g cocoa Δ0.5 ± 0.3%, 5 g cocoa Δ1.0 ± 0.3%, 13 g cocoa Δ1.4 ± 0.2%, and 26 g cocoa Δ2.5 ± 0.4%: P < 0.05 compared with placebo for 5, 13, and 26 g cocoa) on the other study days. A serum marker of cocoa ingestion (total epicatechin) correlated with increased FMD 1- and 2-h postingestion (r = 0.44–0.48; both P < 0.05). Collectively, these results indicate that acute cocoa ingestion dose dependently increases brachial artery FMD in healthy older humans. These responses may help to explain associations between flavonoid intake and cardiovascular-related mortality in humans. PMID:21903881

    A 9-yr-old castrated male dromedary camel (Camelus dromedarius) presented with lethargy and partial anorexia. A diagnostic examination revealed fever, and further workup revealed a neutrophilia, hyperfibrinogenemia, renal azotemia, and a rapid onset of a high Leptospira antibody titer during the acute clinical period (Grippotyphosa serovar). The camel responded clinically to antimicrobial treatment with ceftiofur crystalline free acid injections, but renal azotemia persisted, presumably secondary to chronic renal damage. Subsequent Leptospira polymerase chain reaction testing on urine samples obtained over the following 4 mo revealed no evidence of urinary shedding, so a persistent infection was unlikely. Although often mentioned as a potential cause of reproductive loss, well-documented case reports of clinical leptospirosis in camelids are very rare. In this case, native wildlife contamination of a small watering hole is suspected to have been the source of infection. In response to this experience, the camel and two conspecifics were prescribed a vaccination regimen using an inactivated pentavalent Leptospira vaccine licensed for cattle.

    Choline is a dietary component and precursor of acetylcholine, a crucial neurotransmitter for memory-related brain functions. In two double-blind, placebo-controlled cross-over experiments, we investigated whether the food supplement choline bitartrate improved declarative memory and working memory in healthy, young students one to two hours after supplementation. In experiment 1, 28 participants performed a visuospatial working memory task. In experiment 2, 26 participants performed a declarative picture memorization task. In experiment 3, 40 participants performed a verbal working memory task in addition to the visuospatial working memory and declarative picture task. All tasks were conducted approximately 60 minutes after the ingestion of 2.0–2.5g of either choline bitartrate or placebo. We found that choline did not significantly enhance memory performance during any of the tasks. The null hypothesis that choline does not improve memory performance as compared to placebo was strongly supported by Bayesian statistics. These results are in contrast with animal studies suggesting that choline supplementation boosts memory performance and learning. We conclude that choline likely has no acute effects on cholinergic memory functions in healthy human participants. PMID:27341028

    Pretreatment assessment of cytogenetic/genetic signature of acute myeloid leukemia (AML) has been consistently shown to play a major prognostic role but also to fail at predicting outcome on individual basis, even in low-risk AML. Therefore, we are in need of further accurate methods to refine the patients’ risk allocation process, distinguishing more adequately those who are likely to recur from those who are not. In this view, there is now evidence that the submicroscopic amounts of leukemic cells (called minimal residual disease, MRD), measured during the course of treatment, indicate the quality of response to therapy. Therefore, MRD might serve as an independent, additional biomarker to help to identify patients at higher risk of relapse. Detection of MRD requires the use of highly sensitive ancillary techniques, such as polymerase chain reaction (PCR) and multiparametric flow cytometry(MPFC). In the present manuscript, we will review the current approaches to investigate MRD and its clinical applications in AML management. PMID:27872732
