    The prognostic role of tumor-infiltrating CD45RO(+) memory T lymphocytes (CD45RO(+) T cells) in human solid tumors remains controversial. Herein, we conducted a meta-analysis including 25 published studies with 4720 patients identified from PubMed and EBSCO to assess the prognostic impact of tumor-infiltrating CD45RO(+) T cells in human solid tumors. We found that CD45RO(+) T cell infiltration was significantly associated with improved overall survival (OS) and disease-free survival (DFS) in all types of solid tumors. In stratified analyses, CD45RO(+) T cell infiltration significantly improved 1-year, 3-year and 5-year OS in colorectal, gastric and esophageal cancer, but only 5-year OS in hepatocellular carcinoma. And these cells were positively associated with 1-year, 3-year and 5-year DFS in hepatocellular, colorectal and esophageal cancer. In addition, high density of intratumoral CD45RO(+) T cells inversely correlated with TNM stage of solid tumor. In conclusion, CD45RO(+) memory T lymphocyte infiltration leads to a favorable clinical outcome in solid tumors, implicating that it is a valuable biomarker for prognostic prediction for human solid malignances.

    Colorectal cancer (CRC) accounts for high mortality. So far, there is lack of markers capable of predicting which patients are at risk of aggressive course of the disease. Protein phosphatase-2A (PP2A) inhibitor proteins have recently gained interest as markers of more aggressive disease in certain cancers. Here, we report the role of PP2A inhibitor PME-1 in CRC. PME-1 expression was assessed from a rectal cancer patient cohort by immunohistochemistry, and correlations were performed for various clinicopathological variables and patient survival. Rectal cancer patients with higher cytoplasmic PME-1 protein expression (above median) had less recurrences (P = 0.003, n = 195) and better disease-free survival (DFS) than the patients with low cytoplasmic PME-1 protein expression (below median). Analysis of PPME-1 mRNA expression from TCGA dataset of colon and rectal adenocarcinoma (COADREAD) patient cohort confirmed high PPME1 expression as an independent protective factor predicting favorable overall survival (OS) (P = 0.005, n = 396) compared to patients with low PPME1 expression. CRC cell lines were used to study the effect of PME-1 knockdown by siRNA on cell survival. Contrary to other cancer types, PME-1 inhibition in CRC cell lines did not reduce the viability of cells or the expression of active phosphorylated AKT and ERK proteins. In conclusion, PME-1 expression predicts for a favorable outcome of CRC patients. The unexpected role of PME-1 in CRC in contrast with the oncogenic role of PP2A inhibitor proteins in other malignancies warrants further studies of cancer-specific function for each of these proteins.

    Purpose This study describes how health care providers approach canagliflozin for the treatment of patients with type 2 diabetes mellitus (T2DM) in the real world. Patients and methods An Internet-based questionnaire was completed by 101 endocrinologists, 101 primary care physicians, and 100 nurse practitioners/physician assistants (NP/PAs). Health care providers were required to have experience prescribing or managing patients using canagliflozin to be included in the study. Health care providers compared canagliflozin with other T2DM medication classes on clinical characteristics, costs, and patient satisfaction. Confidence in canagliflozin was also measured. Health care providers reported their canagliflozin prescribing experience and good candidate characteristics for treatment. Finally, providers reported on patient outcomes among those receiving canagliflozin. All variables were compared across provider type. Results Health care providers reported higher favorability for canagliflozin for blood pressure and body weight compared with dipeptidyl peptidase-4 (DPP-4) inhibitors and higher favorability for effect on blood pressure, body weight, treatment satisfaction, and glycosylated hemoglobin (HbA1c) compared with sulfonylureas (SUs), with differences observed for effect on blood pressure. Health care providers reported being very/extremely confident (55%–74%) with canagliflozin as a second-to fourth-line treatment. The top 3 characteristics reported by the providers, in terms of describing a good candidate for canagliflozin, include those concerned about their weight, insurance coverage/affordability, and avoiding injectable treatments. Finally, providers reported often/always observing patients’ lowering or controlling HbA1c (82%–88%) and improvement in overall quality of life (QoL; 50%–53%) with canagliflozin treatment. No differences were observed across provider type for confidence, good candidate characteristics, or patient outcomes. Conclusion

    Occasionally a favorable clinical disease-specific outcome does not reflect into improved generic health-related quality of life (HRQoL) in patients with idiopathic normal pressure hydrocephalus (iNPH) one year after the installation of the cerebrospinal fluid (CSF) shunt. Our aim was to identify factors causing this discrepancy. The one-year HRQoL outcome of 141 iNPH patients was evaluated using the generic 15D instrument, in which the minimum clinically important change/difference on the 0-1 scale has been estimated to be ± 0.015. A 12-point iNPH grading scale (iNPHGS) was used as a clinical disease-specific outcome measure, in which one point decrease is considered to be clinically important. We identified 29 (21%) iNPH patients from our prospective study, whose HRQoL deteriorated or remained the same despite of a favorable iNPHGS outcome. We analyzed this discrepancy using patients' clinical variables and characteristics. Multivariate binary logistic regression analysis indicated that a higher (worse) iNPHGS score at baseline (adjusted OR, 1.7; 95% CI, 1.3-2.3; p < 0.001), comorbid chronic pulmonary disease (40% vs. 20%; adjusted OR, 17.8; 95% CI, 3.6-89.9; p < 0.001) and any comorbid non-metastatic tumor (62% vs. 17%; adjusted OR, 11.5; 95% CI, 1.5-85.3; p = 0.017) predicted discrepancy between iNPHGS and 15D outcomes. Frail patients suffering from certain pre-existing comorbidities may not experience improvement in generic HRQoL despite of a favorable clinical disease-specific response. Acknowledging the comorbidity burden of the patient may help clinicians and the patients to understand the conflict between patient reported and clinical outcomes. Copyright © 2017 Elsevier Inc.

    High dose immunosuppression followed by autologous hematopoietic stem cell transplantation (AHSCT) induces prolonged clinical remission in multiple sclerosis (MS) patients. However, how patient immune profiles are associated with clinical outcomes has not yet been completely elucidated. In this study, 37 MS patients were assessed for neurological outcomes, thymic function and long-term immune reconstitution after AHSCT. Patients were followed for a mean (SD) of 68.5 (13.9) months post-transplantation and were retrospectively clustered into progression- and non-progression groups, based on Expanded Disease Status Scale (EDSS) outcomes at last visit. After AHSCT, both patient groups presented increased regulatory T-cell subset counts, early expansion of central- and effector-memory CD8(+)T-cells and late thymic reactivation. However, the non-progression group presented early expansion of PD-1(+)CD8(+)T-cells and of PD-1-expressing CD19(+) B-cells. Here, we suggest that along with increased numbers of regulatory T-cell subsets, PD-1 inhibitory signaling is one possible immunoregulatory mechanism by which AHSCT restores immune tolerance in MS patients.

    Although tumor-associated macrophages (TAMs) are essential for cancer progression, connections between different clinical outcomes and transcriptional networks have not been reported. We have addressed this issue by analyzing global expression patterns of TAMs isolated from the ascites of ovarian cancer patients. TAMs isolated from different ovarian cancer patients can be stratified by coexpression or principal component analysis into subgroups with specific biological features and associated with distinct clinical outcomes. A hallmark of subgroup A is a high expression of clinically unfavorable markers, including (i) high CD163 expression, a surface receptor characteristic of an anti-inflammatory activation state, (ii) increased PCOLCE2 expression, indicative of enhanced extracellular matrix organization, and (iii) elevated ascites levels of IL-6 and IL-10, linked to the aggressiveness of ovarian cancer and immune suppression. In contrast, subgroup B TAMs are characterized by the upregulation of genes linked to immune defense mechanisms and interferon (IFN) signaling. Intriguingly, analysis of published data for 1763 ovarian cancer patients revealed a strong association of this transcriptional signature with a longer overall survival. Consistent with these results, IFNγ was able to abrogate the suppressive effect of ovarian cancer ascites on the inducibility of IL12B expression and IL-12 secretion, a key determinant of a cytotoxic immune response. The survival of ovarian cancer patients is linked to the presence of TAMs with a transcriptional signature that is characterized by a low expression of protumorigenic and immunosuppressive markers and an upregulation of genes linked to interferon signaling. The observed IFNγ-mediated restoration of the inducibility of IL-12 in the presence of ascites provides a possible explanation for the association of an interferon signaling-associated signature with a favorable clinical outcome.

  7. Favorable outcome of epileptic blindness in children.

    Acute blindness is a rare presentation of epileptic seizures, referring to loss of sight without loss of consciousness associated with electroencephalographic (EEG) epileptic discharges, mainly representing an ictal phase but also either pre- or postictal. We report a series of 14 children with documented epileptic blindness, describing the accompanying fits and thereafter the response to therapy to resolve the blindness and control associated seizures. All patients experienced episodes of acute complete visual obscuration lasting for 1 to 10 minutes. Seven patients hadaccompanying generalized seizures, with a photosensitive response recorded in three of them. All of these seven children were treated with valproic acid, regaining full vision, and six of them became seizure free. Three patients with acute blindness who had accompanying focal motor seizures and unilateral temporooccipital posterior epileptic discharges were treated with carbamazepine regained full vision and complete seizure control. Four additional children had the constellation of migrainous headaches, focal motor phenomena, and complete blindness, along with occipital discharges compatible with Gastaut syndrome, benign childhood epilepsy with occipital paroxysms. All four patients were started on carbamazepine and became asymptomatic. Our overall experience suggests that epileptic blindness in children is associated with a favorable outcome when promptly diagnosed and treated appropriately, resulting in complete resolution of blindness in all children and satisfactory control of seizures in most of them. We therefore recommend performing a prompt EEG in any child presenting with acute visual obscuration, even in the absence of other epileptic phenomena.

    The identification of reliable prognostic markers that distinguish patients' status and predict therapeutic response can improve the clinical outcomes of pancreatic cancer patients. The epithelial cell adhesion molecule (EpCAM) is known to be highly expressed in cancers and serves as a prognosis factor. Generally, membranous EpCAM expression in cancer cells and its clinical significance are evaluated. However, there is also an evidence of cytoplasmic EpCAM distribution in cancer cells. Hence, we investigated which kind of the immunostaining pattern in pancreatic cancer patients was, and whether membranous or cytoplasmic immunostaining had clinical significance. We determined the cytoplasmic or membranous EpCAM expression by a well-established immunohistochemical staining protocol in 157 pairs of carcinoma and paired adjacent non-tumor pancreatic tissue samples using the EpCAM-specific antibody. Furthermore, we evaluated the relationship between tumoral EpCAM expression of resected specimens and patient's overall survival as well as other biological variables like clinical prognosis by Kaplan-Meier method and χ(2) test. We found that pancreatic cancer patients had expressed higher level of cytoplasmic EpCAM but lower level of membranous EpCAM, and their expressions were significantly correlated. Cytoplasmic EpCAM acted as a favorable prognosis factor on survival time in patients with HBV negative infection. Pancreatic cancer patients with cytoplasmic EpCAM over-expression and negative Hepatitis B virus infection might benefit further from post-surgery chemotherapy. These data suggested a potential role of cytoplasmic EpCAM in predicting patient's prognosis and determining therapeutic strategy.

  9. Clinical characteristics and favorable long-term outcomes for patients with idiopathic inflammatory myopathies: a retrospective single center study in China

    PubMed Central

    2011-01-01

    Background Little is known about the clinical features and true survival risk factors in Chinese Han population. We conducted the current study to investigate the clinical features, long-term outcome and true potential indicators associated with mortality of idiopathic inflammatory myopathies (IIM) in China. Methods We restrospectvely investigated 188 patients diagnosed with IIM at our hospital from January 1986 to April 2009. The primary outcome was determined with mortality. The secondary outcomes for survival patients were organ damage and disease activity, health status, and disability, which were assessed with Myositis Damage Index, Myositis Disease Activity Assessment Visual Analogue Scales, Health Assessment Questionnaire Disability Index, and the Modified Rankin Scale, respectively. Potential prognostic factors for mortality were analyzed with the multivariate Cox regression model. Results Mean age at disease onset was 43.8 ± 15.8 years and male to female ratio was 1:2.1 in this cohort. The 1-, 5-, 10-, 15- and 20-year survival rates were 93.6%, 88.7%, 81%, 73.6% and 65.6%. The independent predicators for mortality were age at disease onset [hazard ratio (HR):1.05, 95% CI 1.02 - 1.08], presence of cancer (HR:3.68, 95%CI 1.39 - 9.74), and elevated IgA level at diagnosis (HR:2.80, 95% CI 1.16-6.74). At the end of the follow-up, 29 patients manifested drug withdrawal within an average 4.1 years (range 0.5-15.2 year), most patients (85.9%) had no disease activity and 130 patients (83.4%) had no disability. Conclusions The long-term outcomes of IIM patients in our cohort have improved dramatically. Those patients most likely to survive had a high chance of reaching stable disease status, and obtained long-term or possibly permanent remission to a large extent. PMID:22070623

    Tumor immunity has been suggested to play a key role in clinical and biological behavior of neuroblastomas. Given that CD1-restricted invariant natural killer T (iNKT) cells enhance both innate and acquired tumor immunity, we investigated the expression of the iNKT-cell-specific T-cell receptor Vα24-Jα18 in neuroblastoma tissues and its correlation with clinical and biological characteristics. Using real- time quantitative PCR, we quantified the expression of Vα24-Jα18 in untreated tumor samples from 107 neuroblastoma cases followed in our institution and analyzed the correlation between the presence of infiltrated iNKT cells and clinical characteristics or patients' outcome. Vα24-Jα18 receptor was detected in 62 untreated cases (57.9%). The expression was significantly higher in stages 1, 2, 3, or 4S (P = 0.0099), in tumors with low or intermediate risk (P = 0.0050), with high TrkA expression (P = 0.0229), with favorable histology (P = 0.0026), with aneuploidy (P = 0.0348), and in younger patients (P = 0.0036). The overall survival rate was significantly higher in patients with iNKT-cell infiltration (log-rank; P = 0.0089). Since tumor-infiltrating iNKT cells were predominantly observed in neuroblastomas undergoing spontaneous differentiation and/or regression, we suggest that iNKT cells might play a key role in these processes.

    A 36-year-old man started to climb Mount Fuji (3776m above sea level: ASL), from the Gotemba new fifth station (2400m ASL). He had no significant medical history, and this was his first attempt to climb such a high mountain. He began feeling chest discomfort but continued to climb. When he reached the ninth station of the mountain (3600mASL), he lost consciousness. One individual immediately provided basic life support using an automated external defibrillator (AED) that was located in the station. After electroshocks, he regained consciousness. He was transported to the fifth station, where an ambulance could approach, in a large crawler. When the medical staff, who were transported via helicopter and ambulance, examined him near the fifth station, he still complained of chest discomfort. A single spray of nitroglycerin and aspirin (200mg) was administered. He was transported to the Cardiac Care Unit via ambulance and helicopter under escort by a physician. A chest computed tomography angiogram indicated triple-vessel disease. He was discharged without any neurological deficits after undergoing bypass surgery. In high mountains that can be easily accessed by amateur climbers who may have cardiac disease, the placement of AED devices and the establishment of the chain of survival from the scene to the intensive care unit are essential for obtaining a favorable outcome when a climber suffers cardiac arrest.

    Open globe eye injuries can have profound social and economic consequences. Here, we describe two cases of war and outdoor activity open globe eye injury where, despite a low OTS score, current microsurgical technology allowed for a favorable outcome. A 33-year-old Libyan soldier had been treated for an open-globe grenade blast trauma to his left eye, which showed light perception and OTS score 2. He had undergone a lensectomy and PPV with silicone oil tamponade. Surgical treatment included scleral buckling, cornea trephination, temporary Eckardt keratoprosthesis, PPV revision, intraocular lens (IOL) implantation, and corneal grafting. Six months later, his VA was improved to 20/70. CASE REPORT 2: A 35-year-old man presented with a corneal laceration in his left eye from a meat skewer, with marked hypotony and LP. After primary corneal wound closure, B-scan ultrasonography revealed massive vitreous hemorrhage (OTS score 2). The patient underwent open cataract extraction with IOL implantation, 23 gauge PPV, laser photocoagulation of the retinochoroidal laceration, and a gas tamponade. After three weeks, the patient underwent a 2nd 23G PPV due to a fibrinous reaction. Six month later, the patients exhibited 20/25 VA. These cases confirm that even for patients with a low OTS and poor visual prognosis, an up-to-date surgery protocol may achieve visual results adequate for leading an autonomous daily life.

    The relation between clinical quality and bond rating for nonprofit hospitals has been proposed but never fully studied. We analyzed the relation between bond rating, clinical quality measures (The Joint Commission/Centers for Medicare and Medicaid Services [CMS] core measures), and balance sheet and income statement financial measures of 236 hospitals across the United States that are rated by Moody's Investors Service and that reported clinical quality measures to CMS during the study period. We found a statistically significant relation between higher quality measures and more favorable bond ratings. This association remained significant after controlling for traditional financial parameters.

    Traumatic brain injury (TBI) causes more than 2.5 million emergency department visits, hospitalizations, or deaths annually. Prehospital endotracheal intubation has been associated with poor outcomes in patients with TBI in several retrospective observational studies. We evaluated the relationship between prehospital intubation, functional outcomes, and mortality using high quality data on clinical practice collected prospectively during a randomized multicenter clinical trial. ProTECT III was a multicenter randomized, double-blind, placebo-controlled trial of early administration of progesterone in 882 patients with acute moderate to severe nonpenetrating TBI. Patients were excluded if they had an index GCS of 3 and nonreactive pupils, those with withdrawal of life support on arrival, and if they had documented prolonged hypotension and/or hypoxia. Prehospital intubation was performed as per local clinical protocol in each participating EMS system. Models for favorable outcome and mortality included prehospital intubation, method of transport, index GCS, age, race, and ethnicity as independent variables. Significance was set at α = 0.05. Favorable outcome was defined by a stratified dichotomy of the GOS-E scores in which the definition of favorable outcome depended on the severity of the initial injury. Favorable outcome was more frequent in the 349 subjects with prehospital intubation (57.3%) than in the other 533 patients (46.0%, p = 0.003). Mortality was also lower in the prehospital intubation group (13.8% v. 19.5%, p = 0.03). Logistic regression analysis of prehospital intubation and mortality, adjusted for index GCS, showed that odds of dying for those with prehospital intubation were 47% lower than for those that were not intubated (OR = 0.53, 95% CI = 0.36-0.78). 279 patients with prehospital intubation were transported by air. Modeling transport method and mortality, adjusted for index GCS, showed increased odds of dying in those transported by ground

    Head and neck cancer (HNC) patients tend to develop dysphagia. In order to preserve the nutritional support, many undergo endoscopic gastrostomy (PEG). In HNC patients, ostomy metastasis is considered a rare complication of PEG, but there are no reports of successful treatment of these metastatic cancers. We report the case of a 65 years old pharyngeal/laryngeal cancer patient who underwent a PEG before the neck surgery. He was considered to be cured, resumed oral intake and the PEG tube was removed. Ten months after, he returned with a metastasis at the ostomy site. A block resection of the stomach and abdominal wall was performed. Two years after the abdominal surgery, he is free of disease. Although usually considered a rare complication of the endoscopic gastrostomy, ostomy metastasis may be more frequent than usually considered and the present case report demonstrates that these patients may have a favourable outcome.

    To describe the clinical features, histologic characteristics, and management of patients with pleomorphic xanthoastrocytoma (PXA), we reviewed data on 13 children who had histologically confirmed PXA and were referred to the neuro-oncology service between 1985 and 1999. Neuro-imaging with CT and/or MRI documented the anatomic location, tumor extent, and degree of resection. There were 3 males and 10 females; median age was 12.9 years (range, 8.2-17.2 years). The most frequent presentations included seizures (n = 8) and headache (n = 5). Tumor sites included temporal (n = 5), parietal (n = 3), frontal (n = 1), frontoparietal (n = 1), parietooccipital (n = 1), and temporoparietal (n = 1) lobes and the spinal cord (n = 1). CT/MRI revealed a cystic component in 6 patients, with cyst wall enhancement in 3 patients. The solid component was uniformly enhancing in 11 patients. Vasogenic edema was present in 9 patients, and calcification was noted in 4 patients. Histopathologic findings included meningeal invasion in 12 patients, calcifications in 4, and necrosis in 2. Mitotic figures (1-12 per high-power field) were seen in 8 patients. Gross total resection was achieved in 8 patients, near total resection in 1, and subtotal resection in 4. Ten patients were alive with a median follow-up of 41 months at this writing. Two patients died of progressive disease, and 1 died of an unrelated cause. In conclusion, pleomorphic xanthoastrocytoma is a rare neoplasm in childhood, commonly presenting with seizures. Gross total resection without adjuvant therapy provides prolonged disease control, as seen in 6 of 7 patients (85%) in our series. PMID:11465399

    Our purpose was to assess outcome of patients with early-stage, favorable (per GHSG criteria) Hodgkin Lymphoma (HL) staged with FDG-PET/CT and treated with two cycles of adriamycin, bleomycin, vincristine, and dacarbazine (ABVD) followed by PET/CT assessment and involved-site radiotherapy (ISRT) to 20 Gy. Records of 23 patients who met eligibility criteria, treated between 2008 and 2016, were reviewed. PET response after two cycles of ABVD was independently assessed by a nuclear medicine physician. After two cycles of ABVD, 91.3% of patients had a Deauville score of 1-2; 1 patient had a score of 3. Median follow-up was 45.3 months. As of this analysis, all patients are alive without disease. One patient had an out-of-field relapse, yielding a 4-year relapse-free survival rate of 92.9% (95%CI [59.1, 99.0]). Our results showed that with careful patient selection by initial disease characteristics and FDG-PET response to chemotherapy, the use of a more restricted treatment volume of ISRT to 20 Gy following ABVD × 2 is associated with excellent outcomes.

    To explore the influence of several estimates of family socioeconomic status on the long-term clinical course and social outcomes of children with epilepsy. The Nova Scotia childhood epilepsy cohort is population based and includes all children in this Canadian province who developed epilepsy between 1977 and 1985. Eligible patients had ≥10 years of follow-up. Children with childhood absence epilepsy were excluded. Total family income at seizure onset was assessed at seizure onset and classified as "poor" (first quintile), "adequate" (second to third quintiles), and "well-off" (fourth to fifth quintiles). We also assessed parental education and home ownership. Social outcome was assessed in those with normal intelligence who were ≥18 years of age at the end of follow-up using a semistructured interview that explored eight adverse effects. Of 584 patients, 421 (72%) were included. Average follow-up was 26 ± 5.6 years. Overall 137 families (33%) had "poor" income, 159 (38%) had "adequate income," and 125 (30%) were "well-off." Terminal remission of epilepsy occurred in 65% of the poor, 61% of the adequate, and 61% of the well-off (p = ns). Intractable epilepsy, status epilepticus, number of antiepileptic drugs (AEDs) used, and the number of generalized tonic-clonic or focal with secondary generalization seizures through the clinical course was the same in all groups. Home ownership did not predict remission. Neither paternal nor maternal education was associated with remission. Poor children had significantly more adverse social outcomes including failure to graduate from high school, unemployment, personal poverty, inadvertent pregnancy, and psychiatric diagnoses. In Nova Scotia with universal health care, coming from a poor or more affluent family does not seem to affect the clinical course or long-term seizure outcome of childhood epilepsy. Unfortunately children from poor families are less likely to have a good social outcome. Wiley Periodicals, Inc

  20. Regenerative Endodontic Procedures: Clinical Outcomes.

    Immature teeth are at risk for pulp necrosis, resulting in arrested root development and poor long-term prognosis. There is growing evidence that regenerative endodontic procedures promote desirable clinical outcomes. Despite significant advances in the field of regenerative endodontics and acceptable clinical outcomes, current evidence suggests that the tissues formed following currently used procedures do not completely recapitulate the former pulp-dentin complex. Further research is needed to identify prognostic factors and predictors of successful outcomes and to develop different treatment strategies to better predictably achieve all identified clinical outcomes, while favoring tissue formation that more closely resembles the pulp-dentin complex.

    Summary Purpose Intracranial electroencephalography (EEG) is performed as part of an epilepsy surgery evaluation when noninvasive tests are incongruent or the putative seizure-onset zone is near eloquent cortex. Determining the seizure-onset zone using intracranial EEG has been conventionally based on identification of specific ictal patterns with visual inspection. High-frequency oscillations (HFOs, >80 Hz) have been recognized recently as highly correlated with the epileptogenic zone. However, HFOs can be difficult to detect because of their low amplitude. Therefore, the prevalence of ictal HFOs and their role in localization of epileptogenic zone on intracranial EEG are unknown. Methods We identified 48 patients who underwent surgical treatment after the surgical evaluation with intracranial EEG, and 44 patients met criteria for this retrospective study. Results were not used in surgical decision making. Intracranial EEG recordings were collected with a sampling rate of 2,000 Hz. Recordings were first inspected visually to determine ictal onset and then analyzed further with time-frequency analysis. Forty-one (93%) of 44 patients had ictal HFOs determined with time-frequency analysis of intracranial EEG. Key Findings Twenty-two (54%) of the 41 patients with ictal HFOs had complete resection of HFO regions, regardless of frequency bands. Complete resection of HFOs (n = 22) resulted in a seizure-free outcome in 18 (82%) of 22 patients, significantly higher than the seizure-free outcome with incomplete HFO resection (4/19, 21%). Significance Our study shows that ictal HFOs are commonly found with intracranial EEG in our population largely of children with cortical dysplasia, and have localizing value. The use of ictal HFOs may add more promising information compared to interictal HFOs because of the evidence of ictal propagation and followed by clinical aspect of seizures. Complete resection of HFOs is a favorable prognostic indicator for surgical outcome. PMID

    In a representative UK study (N = 1000) the link between distributive fairness perceptions, outcome favorability, identity, and tax compliance was researched in the context of European transfer payments. Results showed that both forms of tax compliance (i.e., individual and collective EU-tax compliance) were influenced by perceived distributive fairness judgments of EU transfer payments. Fairness itself was related to perceived outcome favorability (i.e., whether their own nation benefits from the EU in financial as well as socio-political terms). Additionally, national identifiers (i.e., people identifying with their own nation, but not with Europe) perceived EU membership as unbeneficial in financial as well as in socio-political terms and thus considered the transfer payments as less fair. Dual identifiers (i.e., people identifying with their own nation and with Europe) perceived the socio-political outcomes from EU membership as more beneficial and thus evaluated the transfer payments as fairer.

    Background Childhood immune thrombocytopenic purpura (ITP) is a common acquired bleeding disorder. Even though most children recover, either spontaneously or with therapy, 10-20% of newly diagnosed ITP cases have a chronic course beyond 12 months. This study evaluated whether clinical and laboratory findings can predict the response to intravenous immunoglobulin (IVIG) and progression to persistent or chronic ITP in children. Methods During the period between March 2003 and June 2015, we retrospectively analyzed 72 children, newly diagnosed with ITP, who received IVIG treatment. Peripheral blood counts were obtained at diagnosis and at 1, 3, 6, and 12 months after IVIG treatment. Results After 6 months of IVIG treatment, 14 of 72 patients (19.4%) had persistent ITP, and after 12 months, 7 of 40 patients (17.5%) had chronic ITP. Age at diagnosis, gender, history of viral infection, or vaccination before disease onset were not statistically correlated with platelet recovery at 6 and 12 months. However, a platelet count recovery of ≥100×103/µL at 1 and 3 months was significantly correlated with platelet recovery at 6 (P<0.001 and P<0.001, respectively) and 12 (P=0.007 and P=0.004, respectively) months. Conclusion This study demonstrated that early platelet count recovery, at 1 and 3 months after IVIG treatment, predicts a short disease duration and a favorable outcome in children with newly diagnosed ITP. Further investigation in a larger group of patients is warranted to validate these findings. PMID:27382553

    Whether to withhold recanalization treatment when the diffusion-weighted imaging (DWI) lesion exceeds a given volume is unsettled. Our aim was to assess the impact of recanalization on outcome in patients with baseline DWI lesion ≥70 mL (DWI≥70 mL) treated ≤4.5 hours from onset. We hypothesized that recanalization is beneficial in a sizeable fraction of these patients and that this is associated with a larger DWI lesion reversal. We analyzed 267 consecutive patients treated with intravenous recombinant tissue-type plasminogen activator for middle cerebral artery territory stroke in whom an occlusion was present on magnetic resonance angiography and 24-hour recanalization and 90-day clinical outcome could be assessed. After stratification relative to the 70-mL DWI lesion cut point, we calculated the odds ratio for recanalization of the primary arterial occlusive lesion (AOL score ≥2) to predict favorable outcome (modified Rankin scale score ≤2). DWI lesion reversal was compared between recanalizers with DWI≥70 mL with favorable and unfavorable outcomes. Median (interquartile range) DWI lesion volume was 22 mL (10-60), and median onset time to imaging was 116 minutes (86-151). Twelve (22%) of the 54 patients with DWI≥70 mL experienced favorable outcome, of which 9 had recanalized. In patients with DWI≥70 mL, recanalization was significantly associated with favorable outcome after adjustment for age and National Institutes of Health Stroke Scale (odds ratio =4.72 [1.09-20.32]; P=0.0375). Among recanalizers with DWI≥70 mL, absolute and relative DWI reversal volumes were larger in those with favorable as compared with unfavorable outcome (18.8 mL [12.2-47.6] versus 8.5 mL [4.3-31.1]; P=0.17; and 19.6% [10.9-62.8] versus 8.7% [3.9-16.5], respectively; P=0.049). Patients with DWI lesion volume ≥70 mL can benefit from recanalization after intravenous recombinant tissue-type plasminogen activator. This may partly reflect a larger amount of DWI lesion

    This study examined hindsight bias for team decisions in a competitive setting in which groups attempted to outperform each other. It was anticipated that, because of self-serving mechanisms, individuals would show hindsight bias only when decision outcomes allowed them to take credit for their own team's success or to downgrade another team for being unsuccessful. MBA students playing a market simulation game made hindsight estimates regarding the likelihood that either their own or another team would perform well. Consistent with a self-serving interpretation, when decision outcomes were favorable individuals evaluating their own team, but not those evaluating another, showed hindsight bias. When outcomes were unfavorable individuals evaluating their own team did not show hindsight bias, but those evaluating another team did. Discussion focuses on implications of hindsight bias in team decision-making settings.

  6. Is there a Relationship between Patient Satisfaction and Favorable Surgical Outcomes?

    PubMed Central

    Tevis, Sarah E.; Kennedy, Gregory D.; Kent, K. Craig

    2015-01-01

    Summary Satisfaction of patients with their health care is gaining importance as a measure of hospital quality due to public reporting of these values and an increasing connection between hospital reimbursement and scores on the current tool to measure satisfaction, the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey. We found that high hospital and surgical volume and low rates of risk-adjusted mortality are associated with high patient satisfaction. However, other favorable patient outcomes are not consistently associated with positive satisfaction scores on HCAHPS. Contributors to patients' perceptions of their care are likely multifactorial and not related just to outcomes traditionally assessed by surgeons or hospitals. Moving in a direction of patient centered care, with a focus on increased understanding and involvement of patients in the care process, will likely strengthen the relationship between surgical outcomes and patient satisfaction.

    A case of postero-medial medullary hematoma in a 21 year-old woman is reported. An initial neurovegetative severe disregulation had a favorable outcome after surgery. Late deficits, characterizing the postero-medial medullary syndrome have been studied: paresis of the tongue, suppression of the nauseous reflex, instability with retropulsion, and downbeating nystagmus in primary position of the eyes were noted. Heart rate and arterial blood pressure analysis showed explosive tachycardic reactions and transitory disappearance of oculo-cardiac reflexes, suggesting the involvement of the efferent parasympathetic system coming from the dorsal motor nucleus of the vagus nerve.

    Gastric localization of post-transplant lymphoproliferative disorders (PTLDs) is very rare. In this study, we aimed to accumulate existing data in the current literature to reveal the clinical, histopathological and prognostic specificities associated with gastric PTLDs and to find the best treatment strategies in this patient population. A comprehensive search was conducted for the available data in the current literature using Pubmed and Google scholar search engines for reports on gastric PTLD in renal transplant recipients. Data of different studies were standardized and entered into a database and analyzed. No statistically significant difference was found between gastric and non-gastric PTLD. Gastric PTLD was relatively more prevalent in female patients (P = 0.08) and showed a trend toward better outcome (P = 0.1) and less metastasis (P = 0.07). Surgical intervention and rituximab therapy were associated with a more favorable outcome (17% mortality). Our study showed that organ transplant recipients having gastric PTLD develop metastasis less frequently and tend to have a relatively more favorable outcome. Prospective studies with larger patient populations are needed to confirm or modify our results.

  9. Local skull trephination before transfer is associated with favorable outcomes in cerebral herniation from epidural hematoma.

    2011-01-01

    The patient with epidural hematoma and cerebral herniation has a good prognosis with immediate drainage, but a poor prognosis with delay to decompression. Such patients who present to nonneurosurgical hospitals are commonly transferred without drainage to the nearest neurosurgical center. This practice has never been demonstrated to be the safest approach to treating these patients. A significant minority of emergency physicians (EPs) have advised and taught bedside burr hole drainage or skull trephination before transfer for herniating patients. The objective of this study was to assess the effect of nonneurosurgeon drainage on neurologic outcome in patients with cerebral herniation from epidural hematoma. A structured literature review was performed using EMBASE, the Cochrane Library, and the Emergency Medicine Abstracts database. No evidence meeting methodologic criteria was found describing outcomes in patients transferred without decompressive procedures. For patients receiving local drainage before transfer, 100% had favorable outcomes. Although the total number of patients is small and the population highly selected, the natural history of cerebral herniation from epidural hematoma and the best available evidence suggests that herniating patients have improved outcomes with drainage procedures before transport. © 2010 by the Society for Academic Emergency Medicine.

    Selection of patients who are viable candidates for cardiac resynchronization therapy (CRT), prediction of the response to CRT as well as an optimal definition of a favorable response, all require further exploration. The purpose of this study was to evaluate the interplay between the prediction of the response to CRT and the definition of a favorable outcome. Seventy patients who received CRT were included. All patients met current guideline criteria for CRT. Forty-three echocardiographic parameters were evaluated before CRT and at 1, 3, 6, and 12 months. M-mode, 2D echocardiography, and Doppler imaging were used to quantify left ventricular (LV) systolic and diastolic function, mitral regurgitation, right ventricular systolic function, pulmonary artery pressure, and myocardial mechanical dyssynchrony. The following definitions of a favorable CRT response were used: left ventricular ejection fraction (LVEF) improvement more >5% acutely following CRT, LVEF improvement >20% at 12-month follow-up, and a LV end-systolic volume (LVESV) decrease >15% at 12-month follow-up. For the LVEF improvement >5%, the best predictor was isovolumetric relaxation time (IVRT; P=.035). For improvement of LVEF >20%, the best predictors were left ventricular stroke index (LVSI; P=.044) and left ventricular fractional shortening (LVFS; P=.031). For the drop in left ventricular systolic volume (LVESV >15%), the best predictor was septal-to-lateral wall delay (ΔT) (P=.043, RR=1.023, 95% CI for RR=1.001-1.045). The definition of a favorable CRT response influenced the optimal predictor variable(s). Standardization of defining a favorable response to CRT is needed to guide clinical decision making processes. © 2017, Wiley Periodicals, Inc.

    Background. Lower back pain is a common reason for disability and the most common cause is lumbar disc herniation. Percutaneous epidural adhesiolysis has been applied to relieve pain and increase the functional capacity of patients who present this condition. Objectives. In this study, we retrospectively evaluated the factors which predict the outcome of percutaneous epidural adhesiolysis in patients who were diagnosed with lumbar disc herniation. Methods. Electronic medical records of patients diagnosed with lumbar disc herniation who have received percutaneous epidural adhesiolysis treatment were reviewed. The primary outcome was the factors that were associated with substantial response of ≥4 points or ≥50% of pain relief in the numerical rating scale pain score 12 months after the treatment. Results. Multivariate logistic regression analysis demonstrated that the presence of high-intensity zone (HIZ) at magnetic resonance imaging was a predictor of substantial response to percutaneous epidural adhesiolysis for 12 months (P = 0.007). The presence of a condition involving the vertebral foramen was a predictor for unsuccessful response after 12 months (P = 0.02). Discussion and Conclusion. The presence of HIZ was a predictor of favorable long-term outcome after percutaneous epidural adhesiolysis for the treatment of lower back pain with radicular pain caused by lumbar disc herniation.

    2014-01-01

    Background The long-term prognosis of clinically early IgA nephropathy (IgAN) patients remains to be clarified. We investigated the long-term outcomes of IgAN patients with an apparently benign presentation and evaluated prognostic factors for renal survival. Methods We included patients with biopsy-proven IgAN who had estimated glomerular filtration rates (eGFR) ≥60 mL/min/1.73 m2, normal blood pressure, and proteinuria <0.5 g/day at the time of biopsy. The primary outcome was progression to end-stage renal disease (ESRD). The secondary outcome was a 50% increase in serum creatinine level or an increase in proteinuria to >1 g/day. Results The analysis included 153 patients who met the inclusion criteria. At diagnosis, their median systolic blood pressure was 120 (110–130) mmHg, eGFR was 85.9 (74.9–100.1) mL/min/1.73 m2, and proteinuria was 0.25 (0.13–0.38) g/day. Of these, 4 patients died and 6 reached ESRD. The 30-year renal survival rate was 85.5%. Three patients had increased serum creatinine levels and 11 developed proteinuria. Remission was observed in 35 (22.9%) patients. A moderate or severe degree of interstitial fibrosis (adjusted odd ratio [OR] 5.93, 95% confidence interval [CI] 1.44–24.45, P = 0.014) and hypoalbuminemia (adjusted OR 6.18, 95% CI 1.20–31.79, P = 0.029) were independent predictors of the secondary outcome. Conclusions This study showed that the prognosis of early IgAN was not always favorable, even resulting in progression to ESRD in some cases. Hypoalbuminemia and interstitial fibrosis should also be considered important prognostic factors in clinically early IgAN patients. PMID:24946688

    Antithrombotics are the mainstay of treatment in primary and secondary prevention of stroke, and their use before an acute event may be associated with better outcomes. Using data from Get With The Guidelines-Stroke with over half a million acute ischemic strokes recorded between October 2011 and March 2014 (n=540 993) from 1661 hospitals across the United States, we examined the unadjusted and adjusted associations between previous antithrombotic use and clinical outcomes. There were 250 104 (46%) stroke patients not receiving any antithrombotic before stroke; of whom approximately one third had a documented previous vascular indication. After controlling for clinical and hospital factors, patients who were receiving antithrombotics before stroke had better outcomes than those who did not, regardless of whether a previous vascular indication was present or not: adjusted odds ratio (95% confidence intervals) were 0.82 (0.80-0.84) for in-hospital mortality, 1.18 (1.16-1.19) for home as the discharge destination, 1.15 (1.13-1.16) for independent ambulatory status at discharge, and 1.15 (1.12-1.17) for discharge modified Rankin Scale score of 0 or 1. Previous antithrombotic therapy was independently associated with improved clinical outcomes after acute ischemic stroke. Ensuring the use of antithrombotics in appropriate patient populations may be associated with benefits beyond stroke prevention. © 2016 American Heart Association, Inc.

    The prognostic value of CSF biomarkers in patients with idiopathic normal pressure hydrocephalus (iNPH) has not been adequately studied to date. The aim of this study was to identify CSF markers of favorable surgical outcome in patients with iNPH undergoing the insertion of a ventriculoperitoneal shunt. Ventricular CSF was collected intraoperatively from 22 patients with iNPH and enzyme-linked immunosorbent assay was used to analyze the levels of amyloid-β 1-42 (Aβ(1-42)) and total tau protein. The Black grading scale was used to assess outcomes at 6 months. Receiver operating characteristic (ROC) curves were obtained and discriminant function analysis was undertaken to provide sensitivity and specificity figures for each marker as well as their combination. The mean age of the patients was 71.45 years (± 9.5 years [SD]). Follow-up was achieved in 21 patients. Seventeen patients had a favorable outcome and 4 patients had unfavorable outcome at 6 months. An Aβ(1-42) level of 180 pg/ml had a sensitivity of 35% and a specificity of 20% for predicting a favorable outcome at 6 months. A total tau level of 767 pg/ml will have a sensitivity of 17% and a specificity of 20% for predicting a favorable outcome at 6 months. A combination of Aβ(1-42) and total tau levels predicted favorable outcomes with a sensitivity of 80% and specificity of 82.4%. In this pilot study a combination of Aβ(1-42) levels and total tau protein levels predicted favorable surgical outcomes at 6 months with adequate accuracy to be of clinical use. Further study in a larger group with longer follow-up is warranted.

    Background Optimal acceptable time intervals from collapse to bystander cardiopulmonary resuscitation (CPR) for neurologically favorable outcome among adults with witnessed out-of-hospital cardiopulmonary arrest (CPA) have been unclear. Our aim was to assess the optimal acceptable thresholds of the time intervals of CPR for neurologically favorable outcome and survival using a recursive partitioning model. Methods and Findings From January 1, 2005 through December 31, 2009, we conducted a prospective population-based observational study across Japan involving consecutive out-of-hospital CPA patients (N = 69,648) who received a witnessed bystander CPR. Of 69,648 patients, 34,605 were assigned to the derivation data set and 35,043 to the validation data set. Time factors associated with better outcomes: the better outcomes were survival and neurologically favorable outcome at one month, defined as category one (good cerebral performance) or two (moderate cerebral disability) of the cerebral performance categories. Based on the recursive partitioning model from the derivation dataset (n = 34,605) to predict the neurologically favorable outcome at one month, 5 min threshold was the acceptable time interval from collapse to CPR initiation; 11 min from collapse to ambulance arrival; 18 min from collapse to return of spontaneous circulation (ROSC); and 19 min from collapse to hospital arrival. Among the validation dataset (n = 35,043), 209/2,292 (9.1%) in all patients with the acceptable time intervals and 1,388/2,706 (52.1%) in the subgroup with the acceptable time intervals and pre-hospital ROSC showed neurologically favorable outcome. Conclusions Initiation of CPR should be within 5 min for obtaining neurologically favorable outcome among adults with witnessed out-of-hospital CPA. Patients with the acceptable time intervals of bystander CPR and pre-hospital ROSC within 18 min could have 50% chance of neurologically favorable outcome. PMID:22194860

    Abstract Background This study searches the National Health Insurance Research Database (NHIRD) used in a previous project, aiming for reconstructing possible cerebrovascular disease-related groups (DRG),and estimating the costs between cerebrovascular disease and related diseases. Methods and Materials We conducted a nationwide retrospective cohort study in stroke inpatients, we examined the overall costs in 3 municipalities in Taiwan, by evaluating the possible costs of the expecting diagnosis related group (DRG) by using the international classification of diseases version-9 (ICD-9) system, and the overall analysis of the re-admission population that received traditional Chinese medicine (TCM) treatment and those who did not. Results The trend demonstrated that the non-participant costs were consistent with the ICD-9 categories (430 to 437) because similarities existed between years 2006 to 2007. Among the TCM patients, a wide variation and additional costs were found compared to non-TCM patients during these 2 years. The average re-admission duration was significantly shorter for TCM patients, especially those initially diagnosed with ICD 434 during the first admission. In addition, TCM patients demonstrated more severe general symptoms, which incurred high conventional treatment costs, and could result in re-admission for numerous reasons. However, in Disease 7 of ICD-9 category, representing the circulatory system was most prevalent in non-TCM inpatients, which was the leading cause of re-admission. Conclusion We concluded that favorable circulatory system outcomes were in adjuvant TCM treatment inpatients, there were less re-admission for circulatory system events and a two-third reduction of re-admission within ICD-9 code 430 to 437, compared to non-TCM ones. However, there were shorter re-admission duration other than circulatory system events by means of unfavorable baseline condition. PMID:24475108

    The authors examine associations of personality characteristics, National Board of Medical Examiners subject examination performance, and Objective Structured Clinical Examination performance with clinical evaluations of third-year medical students in a psychiatry clerkship. Students completed the Revised NEO Personality Inventory, which measures personality domains of neuroticism, extraversion, openness, agreeableness, and conscientiousness and associated personality traits. At clerkship completion, students completed the National Board of Medical Examiners subject examination and a psychiatry Objective Structured Clinical Examination, and were evaluated by attending physicians (using a standardized evaluation form) regarding their clinical "knowledge and skill" and "interpersonal behavior." Data were analyzed using Pearson correlation and canonical correlation. National Board of Medical Examiners subject examination and Objective Structured Clinical Examination scores were uncorrelated with clinical evaluations of "knowledge and skill" and "interpersonal behavior." Personality variables explained a moderate amount of variance in clinical evaluations. "Knowledge and skill" was positively associated with the domain of conscientiousness, the extraversion trait of warmth, and the conscientiousness traits of competence and achievement striving. "Interpersonal behavior" was negatively associated with the neuroticism trait of angry hostility and positively associated with the domain of agreeableness; the extraversion traits of warmth, gregariousness, and positive emotions; and the agreeableness traits of trust, altruism, compliance, and tender-mindedness. Clinical evaluations of medical students may favor personality styles that reflect positive elements of extraversion, agreeableness, and conscientiousness. The present findings raise questions regarding the validity of clinical evaluation elements in clerkship performance appraisal.

    Introduction: Very severe head trauma cases, defined as Glasgow Coma Scale (GCS) scores of less than 6, have a higher mortality rate and poorer outcome. The purpose of this study was to recognize factors associated with survival and 6-month favorable outcome of very severe head trauma patients presenting to emergency department. Methods: In this historical cohort study, the authors retrospectively reviewed medical records of head trauma patients who were admitted to the emergency department with post-resuscitation GCS scores of less than 6. Both univariate and multivariate analyses were used to test the association between various parameters with survival and 6-month outcome. Results: 103 cases with the mean age of 39 ± 16.5 years were studied (80% male). The overall survival rate was 41.7% and the rate of 6-month favorable outcome was 28.2%. In multivariate analysis, brisk pupil light reaction on admission and patent basal cistern on brain computed tomography (CT) scan were significant factors associated with both survival (OR 5.20, 95% CI 1.57-17.246, p = 0.007 and OR 3.65, 95% CI 1.22-10.91, p=0.02 respectively) and favorable outcome (OR 4.07, 95% CI 1.35-12.24, p=0.01 and OR 3.54, 95% CI 1.22-10.26, p 0.02), respectively. Conclusion: Based on the results of present study, the survival rate of patients with very severe head trauma (GCS < 6) was 41.7%. The strong predictors of survival and 6-month favorable outcome of these patients were brisk pupillary reactivity and patent cistern on brain CT scan. It seems that very severe head trauma patients still have a reasonable chance to survive and aggressive management should be continued. PMID:28286831

    It is unclear whether the basic life support (BLS) and advanced life support (ALS) pre-hospital termination of resuscitation (TOR) rules developed in North America can be applied successfully to patients with out-of-hospital cardiac arrest (OHCA) in other countries. To assess the performance of the BLS and ALS TOR in Japan. Retrospective nationwide, population-based, observational cohort study of consecutive OHCA patients with emergency responder resuscitation attempts from 1 January 2005 to 31 December 2009 in Japan. The BLS TOR rule has 3 criteria whereas the ALS TOR rule includes 2 additional criteria. We extracted OHCA patients meeting all criteria for each TOR rule, and calculated the specificity and positive predictive value (PPV) of each TOR rule for identifying OHCA patients who did not have neurologically favorable one-month survival. During the study-period, 151,152 cases were available to evaluate the BLS TOR rule, and 137,986 cases to evaluate the ALS TOR rule. Of 113,140 patients that satisfied all three criteria for the BLS TOR rule, 193 (0.2%) had a neurologically favorable one-month survival. The specificity of BLS TOR rule was 0.968 (95% CI: 0.963-0.972), and the PPV was 0.998 (95% CI: 0.998-0.999) for predicting lack of neurologically favorable one-month survival. Of 41,030 patients that satisfied all five criteria for the ALS TOR rule, just 37 (0.1%) had a neurologically favorable one-month survival. The specificity of ALS TOR rule was 0.981 (95% CI: 0.973-0.986), and the PPV was 0.999 (95% CI: 0.998-0.999) for predicting lack of neurologically favorable one-month survival. The prehospital BLS and ALS TOR rules performed well in Japan with high specificity and PPV for predicting lack of neurologically favorable one-month survival in Japan. However, the specificity and PPV were not 1000 and we have to develop more specific TOR rules. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Citation bias occurs when positive trials involving a medical intervention receive more citations than neutral or negative trials of similar quality. Several large clinical trials have studied the use of thrombolytic agents for the treatment of acute ischemic stroke with differing results, thereby presenting an opportunity to assess these trials for evidence of citation bias. We compared citation rates among positive, neutral, and negative trials of alteplase (tPA) and other thrombolytic agents for stroke. We used a 2014 Cochrane Review of thrombolytic therapy for the treatment of acute stroke to identify non-pilot, English-language stroke trials published in MEDLINE-indexed journals comparing thrombolytic therapy with control. We classified trials as positive if there was a statistically significant primary outcome difference favoring the intervention, neutral if there was no difference in primary outcome, or negative for a significant primary outcome difference favoring the control group. Trials were also considered negative if safety concerns supported stopping the trial early. Using Scopus, we collected citation counts through 2015 and compared citation rates according to trial outcomes. Eight tPA trials met inclusion criteria: two were positive, four were neutral, and two were negative. The two positive trials received 9080 total citations, the four neutral trials received 4847 citations, and the two negative trials received 1096 citations. The mean annual per-trial citation rates were 333 citations per year for positive trials, 96 citations per year for neutral trials, and 35 citations per year for negative trials. Trials involving other thrombolytic agents were not cited as often, though as with tPA, positive trials were cited more frequently than neutral or negative trials. Positive trials of tPA for ischemic stroke are cited approximately three times as often as neutral trials, and nearly 10 times as often as negative trials, indicating the presence of

    ESRPs are master splice regulators implicated in alternative mRNA splicing programs important for epithelial-mesenchymal transition (EMT) and tumor progression. ESRP1 was identified in some tumors as good or worse predictor of outcome, but in colorectal cancer (CRC) the prognostic value of ESRPs and relation with mesenchymal splice variants is not clear. Here, we studied 68 CRC cases, compared tissue expression of ESRPs with clinical data and with EMT gene splice patterns of conditional CRC cells with deficient ESRP1 expression. Around 72% of patients showed global decreased transcript expression of both ESRPs in tumor as compared to matched non-neoplastic colorectal epithelium. Reduction of ESRP1 in tumor cells was evaluated by immunohistochemistry, associated with microsatellite stability and switch to mesenchymal splice signatures of FGFRs, CD44, ENAH and CTNND1(p120-catenin). Expression of ESRPs was significantly associated with favorable overall survival (log-rank test, P=0.0186 and 0.0408), better than prognostic stratification by tumor staging; and for ESRP1 confirmed with second TCGA cohort (log-rank test, P=0.0435). Prognostic value is independent of the pathological stage and microsatellite instability (ESRP1: HR=0.36, 95%CI 0.15–0.91, P=0.032; ESRP2: HR=0.23, 95%CI 0.08–0.65, P=0.006). Our study supports the role of ESRP1 as tumor suppressor and strongly suggests that ESRPs are candidate markers for early detection, diagnosis, and prognosis of CRC. PMID:27650542

    SOX2 is a gene that encodes for a transcription factor, which functions as an activator or suppressor of gene transcription. SOX2 amplification and overexpression have been found in various types of tumors and play important roles in cancer cells. The aim of the study was to evaluate SOX2 expression and amplification in lung squamous cell carcinomas (SCCs) and to determine the relationship with main clinicopathologic features, patient prognosis, and common driver mutations. SOX2 protein levels were measured by immunohistochemistry, while SOX2 copy numbers were measured by fluorescence in situ hybridization in resected samples from 162 Chinese lung SCC patients. All patients were also analyzed for mutations in EGFR, HER2, BRAF, PIK3CA, NFE2L2, and FGFR fusion genes. Clinical characteristics, including age, sex, smoking status, stage, relapse-free survival (RFS), and overall survival (OS), were collected. SOX2 overexpression and amplification were observed in 58.6% and 45.9% of lung SCCs. Lung SCC patients with SOX2 overexpression were significantly associated with absence of malignant tumor family history (P=0.021), FGFR fusion gene (P=0.046), longer RFS (P=0.041), and OS (P=0.025). No correlation was found between SOX2 gene amplification and main clinicopathologic features, patient prognosis, or common driver mutations. SOX2 overexpression and amplification are common in lung SCCs. SOX2 over-expression was associated with FGFR fusion genes and predicted favorable outcome in lung SCCs. The underlying relationship of SOX2 and FGFR still needs further investigation.

    Several tools have been introduced in clinical trials to quantify the severity and the response to a given therapeutic regimen of both psoriasis and psoriatic arthritis. Each method present specific advantages and limitations. Here we will discuss some of the most popular clinical outcome measures of both psoriasis (Psoriasis Severity Index, Physician Global Assessment, National Psoriasis Fundation-Psoriasis Score, Dermatology Life Quality Index) and psoriatic arthritis (American College Rheumatology response criteria, Psoriatic Arthritis Response Criteria).

    In primary central nervous system lymphoma (PCNSL), 2 international prognostic scores have been developed to estimate the outcome according to certain "prognostic groups". However, these scores do not predict the individual course of a single patient under therapy. In this analysis, we addressed the question of whether early tumor remission in patients still under therapy, according to magnetic resonance imaging (MRI) criteria, helps to predict long-term outcome. Eighty-eight patients treated with 6 polychemotherapy cycles within a pilot/phase II trial underwent MRI scanning within 72 hours prior to initiation of therapy, after the second chemotherapy cycle, and after completion of chemotherapy. Response was assessed by contrast-enhanced MRI of the brain according to the Macdonald criteria. Median follow-up was 42 months (range, 0-124 months). Patients achieving a complete radiographic response after 2 courses of chemotherapy (n = 18) had a significantly longer median overall survival (OS) (not reached) and median time-to-treatment failure (TTF) (not reached) than patients with complete response (CR) after termination of treatment but with only a partial response after the second cycle (n = 24) (OS: 55 months; TTF: 32 months) (P < .01). Early complete tumor response assessed by MRI after the second of sixth scheduled chemotherapy cycles was highly predictive for both OS and TTF in patients with PCNSL treated in this series.

    We present patient reported outcomes from our 5-year experience using penile plication to correct a wide variety of Peyronie disease malformations. We reviewed the records of all men who underwent penile plication for Peyronie disease, as performed by one of us (AFM). All patients were treated with tunical plication without penile degloving via a 2 cm longitudinal penile incision regardless of curvature severity or erectile function. A concomitant inflatable penile prosthesis was placed in men with refractory erectile dysfunction. A questionnaire was administered to assess the patient perception of postoperative penile curvature, length, rigidity and adequacy for intercourse. Of 154 treated patients 78 (51%) and 65 (42%) had simple (less than 60 degrees) and complex (biplanar curvature, or curvature 60 degrees or greater) malformation, respectively, while 11 (7%) underwent plication plus inflatable penile prosthesis placement. A total of 132 patients responded to the questionnaire a mean 14 months after surgery. Overall, 96% of patients reported curvature improvement after penile plication, 93% reported erection adequate for sexual intercourse and 95% considered that the overall condition improved after surgery. Despite a significant difference in the number of plication sutures (mean 10 vs 7) and curvature angle correction (mean 57 vs 30 degrees, each p <0.005), self-reported outcomes of complex cases were equivalent to those of simple cases. While 84% of patients had no measureable decrease in stretched penile length, 103 of 154 (78%) reported a perceived penile length reduction after surgery. Penile plication without degloving is effective for correcting a wide variety of Peyronie disease malformations. It can be safely combined with inflatable penile prosthesis placement.

    HHV8/EBV-associated germinotropic lymphoproliferative disorder (GLD) is a challenging diagnosis given its rarity, the particular clinical presentation, and the lack of expression of markers usually used in establishing hematopoietic lineage. We report a new case of HHV8/EBV GLD in an immunocompetent 78-year-old woman. The diagnosis was made in an incidentally discovered lymphadenopathy. Histological examination showed a nodular lymphoid proliferation centered by aggregates of atypical plasmablastic cells admixed with small lymphoid cells. Tumor cells were strongly positive with EMA, HHV8, LMP1, CD38, CD138, and kappa light chains. They were negative with common lymphoma-associated markers (CD20, CD3, CD15, CD30, CD10, and bcl2). In situ hybridization confirmed the monotypic kappa light chains and the EBV infection (EBER+). A polyclonal pattern of Ig gene rearrangement was detected by PCR analysis. In the adjacent lymph node parenchyma, some germinal centers mimicked Castleman disease. In this case, the differential diagnosis was discussed with an early stage of large B-cell lymphoma arising in HHV8-associated multicentric Castleman disease. The clinical presentation, the immunophenotype, and the molecular results helped to make the accurate diagnosis. Through the review of the nine previously reported cases in literature, we discuss the clinical and pathologic features and the differential diagnosis of HHV8/EBV GLD. PMID:28280640

    Zygomycosis or mucormycosis is an increasingly frequent life-threatening infection caused by opportunistic fungal organisms of the class Zygomycetes. The pathognomonic feature is the presence of invasive aseptate mycelia that are larger than other filamentous fungi with the hyphae exhibiting right angle and haphazard branching. Usually classified as rhinocerebral, disseminated, and cutaneous types, this classification serves as important predictor of pathogenesis and outcome. These occur mostly in immunosuppressed patients including individuals with diabetes (43% exhibit the rhino-cerebral form) and patients with organ transplants and hematologic malignancies. Without early aggressive treatment, the disease follows a dismal and fatal course. The prognosis has not shown any appreciable change in the past 40 years with a stagnant mortality rate of 44%. We present 2 cases of rhinocerebral zygomycosis (RCZ), in a 58-year-old male and a 63-year-old female; both were poorly controlled diabetic patients with maxillary lesions suggestive of osteomyelitis. The patients were leading a near normal life with minimal discomfort or signs and symptoms of underlying mycosis. Most of the health care professionals treating these patients often overlooked the disease or recommended inadequate therapy. Despite long delays and inadequate initial therapy these patients survived with little outward morbidity. The prognosis for this condition may therefore be considered less dire than previously thought.

    The effect of varicocele repair on male fertility remains controversial. It would be helpful to determined which men would benefit most from varicocele repair, and target repair efforts at those individuals. A detailed review of the literature on prognostic factors for varicocele repair was performed using the PubMed NLM database. We found that the best predictor of postvaricocelectomy semen parameters is the preoperative semen parameters. The greatest improvements in semen parameters were found in men with larger varicoceles. While there is controversy, higher testosterone, younger age and larger testis size, in some studies predict for improvements in semen parameters postvaricocelectomy. A nomogram has been developed to predict the postvaricocelectomy semen parameters based on the preoperative semen parameters, varicocele grade and the age of the man (www.fertilitytreatmentresults.com). Limited data consistently demonstrates the greatest improvements in DNA fragmentation rates in men with higher baseline DNA fragmentation rates. With respect to reproductive outcomes, higher baseline sperm density consistently predicts for natural pregnancy or assisted reproductive technology (ART) pregnancy rates. In addition, varicocele repair does seem to reduce the need for more invasive modalities of ART. In conclusion, we can now start to use specific parameters such as baseline semen quality, varicocele grade and patient age to predict post-repair semen quality and fertility potential following varicocelectomy.

    We have analyzed in lymph nodes at diagnosis of 75 patients with follicular lymphoma (FL) the relationship between different T-cell subpopulations, assessed by immunohistochemistry (IHC) and flow cytometry (FC), with the outcome. CD4(+) cells were the most abundant T-cells in tumor tissue sections, whilst CD57(+) cells were the less frequent. In addition to nonambulatory performance status, advanced stage and FLIPI, low CD4(+)CD57(+)/CD4(+) ratio (p = .041), and low CD4(+)/CD8(+) ratio (p = .008) predicted poor overall survival (OS). Multivariate analysis showed that CD4(+)CD57(+)/CD4(+) ratio was the most important variable for OS. In conclusion, T-cell subpopulations, including CD4(+)CD57(+)/CD4(+) ratio analyzed by FC, could identify FL patients with favorable outcome.

    The aim of the study is to determine how specific EEG findings during neonatal period correlate with clinical outcome on follow-up. This is a retrospective study of 118 term newborns who had EEG in the first month of life and subsequent clinical assessment between 4 and 16 years. Clinical neurologic outcome was classified into "favorable" when patients had no or only mild limitation in assessment, "unfavorable" when patients had moderate to severe abnormalities in assessment, and "epilepsy" when patients had seizures. Of the 118 neonates, 36 (30.5%) had favorable and 82 (69.5%) had unfavorable outcome; 89 (75.4%) had epilepsy and 28 (23.7%) had not. Sixty-seven (57%) had abnormal EEG background of which 56 had both unfavorable outcome and epilepsy; 102 (86%) had sharp transient discharges of which 75 had unfavorable outcome; 20 (17%) had ictal epileptiform discharges of which 18 had unfavorable outcome; 98 (83%) had abnormal overall EEG impression of which 77 had unfavorable outcome and 80 had epilepsy. Abnormal EEG background (particularly suppression) during neonatal period may be predictive of Unfavorable outcome. Overall impression of EEG may be predictive of clinical outcome, even when individual parameters were not predictive. Other findings did not appear to be predictive.

    Fournier gangrene (FG), a form of necrotizing fasciitis of the perineum and genitals, with high morbidity and mortality in the general population, carries the additional risk of involvement of the peritoneal catheter tunnel and peritoneal cavity in patients on chronic peritoneal dialysis (PD). We describe two men with diabetes who developed FG in the course of PD. Computed tomography showed no extension of FG to the abdominal wall, and spent peritoneal dialysate was clear in both patients. Broad-spectrum antibiotic therapy with anaerobic coverage and early aggressive debridement followed by negative-pressure wound therapy and repeated debridement led to improvements in clinical status in both cases. Surgical closure and healing of the wound was achieved in one patient; the wound of the second patient is healing, but remains open. Both patients experienced prolonged hospitalization, with a serious decline in nutrition status. In patients on PD, FG can be treated successfully. However, additional measures are required to evaluate for potential involvement of the PD apparatus and the peritoneal cavity in the infectious process; and prolonged hospitalization, worsening nutrition, and multiple surgical interventions can result.

    To explore the role of middle latency evoked potentials (EPs) as predictors for favorable outcome in patients with severe ischemic brain injuries by comparing the prognostic ability of short latency somatosensory and auditory evoked potentials (SLSEP and BAEP) with middle latency somatosensory and auditory evoked potentials (MLSEP and MLAEP). MLSEP, MLAEP, SLSEP and BAEP were recorded in 112 patients with severe ischemic brain injuries (Glasgow Coma Scale ≤ 8). Among them, 83 patients suffered from cerebral ischemic stroke and 29 suffered from anoxic-ischemic encephalopathy after cardiopulmonary resuscitation between 1 and 7 days after the onset of stroke. Outcomes were reviewed 6 months later using the Glasgow Outcome Scale (GOS). A GOS score of 4-5 was considered as a good outcome while a score of 1-3 was considered as poor. By using the prognostic authenticity analysis of predictors for good outcome, at least unilateral N20 of the SLSEP exit and at least unilateral N60 of the MLSEP exit showed the highest sensitivity which was 100% (95% CI: 86.7%-100%). The bilateral normal N60 showed a high specificity of 97.5% (95% CI: 90.4%-99.6%). It also showed the highest positive likelihood ratio of 6.25% (95% CI: 1.28%-30.59%), which was superior to N20 of SLSEP, V of BAEP, and Pa of MLAEP. The analysis demonstrated that the area under the curve for MLSEP grading was the highest (0.838) compared to that of SLSEP grading (0.784), MLAEP grading (0.659) and BAEP grading (0.621). Compared with using N20 of SLSEP analysis alone, adding MLSEP improves the outcome prediction in patients with severe ischemic brain injuries. When an outcome is uncertain after initial evaluation using short-latency EPs, MLSEP is valuable to be used from the first week to further improve prognostication in these patients.

    Peripheral eosinophilia after allogeneic stem cell transplant (ASCT) may reflect the activation of the Th2 cytokine pathway. A retrospective analysis was performed to evaluate the impact of early- (before day 100: EEo) or late-onset (beyond day 100: LEo) eosinophilia (> or =0.5 x 10(9)/L in peripheral blood) on transplant outcomes after peripheral blood SCT (PBSCT) in 237 patients. The incidence of EEo and LEo was 43% at day 100 and 62% at 2 years, respectively. Compared with patients without LEo, improved transplant outcomes were observed in patients with LEo: better overall survival (OS; 86% versus 41%, P = 5 x 10(-11)), lower nonrelapse mortality (NRM; 10% versus 37%, P = 3 x 10(-6)), lower relapse incidence (11% versus 31%, P = 3 x 10(-5)), and higher GVHD-specific survival (GSS; 90% versus 64%, P = 1 x 10(-6)) were observed. In addition, similar finding was observed when transplant outcomes were analyzed according to the occurrence of eosinophilia at the onset of cGVHD. The multivariate analyses confirmed a favorable implication of LEo on OS, NRM, and GSS. LEo was associated with: (1) less severe chronic GVHD (cGVHD), (2) higher prevalence of autoantibodies, and (3) rapid lymphocyte count recovery after ASCT. In summary, the development of eosinophila after allogeneic PBSCT seemed to be a prognostic marker for improving transplant outcome.

    It remains unclear whether men selecting active surveillance (AS) are at increased risk of unfavorable longer term outcomes as compared with men who undergo immediate treatment. To compare adverse pathologic outcomes in men with favorable-risk prostate cancer who underwent delayed prostatectomy after surveillance (DPAS) to those who elected immediate prostatectomy (IRP). We conducted a retrospective analysis of a prospective AS registry from 2004 to 2014. From the Johns Hopkins AS program (n = 1298), we identified a subset of men who underwent DPAS (n = 89) and was representative of the entire cohort, not just those that were reclassified to higher risk. These men were compared with men who underwent IRP (n = 3788). We measured adverse pathologic features (primary Gleason pattern ≥ 4, seminal vesicle invasion [SVI], or lymph node [LN] positivity). Multivariable models were adjusted for age, prostate-specific antigen density, and baseline risk classification. Delayed prostatectomy occurred at a median of 2.0 yr (range: 0.6-9.0) after diagnosis. The DPAS and IRP cohorts demonstrated similar proportions of men with primary Gleason pattern ≥ 4 (17% vs 20%; p = 0.11), SVI (3.3% vs 3.2%; p = 0.53), LN positivity (2.3% vs 1.2%; p = 0.37), and overall adverse pathologic features (21.3% vs 17.0%; p = 0.32). The adjusted odds ratio of adverse pathology was 1.33 (95% confidence interval, 0.82-2.79; p = 0.13) for DPAS as compared with IRP. Limitations include a modest cohort size and a limited number of events. In men with favorable-risk cancer, the decision to undergo AS is not independently associated with adverse pathologic outcomes. This report compares men with favorable-risk prostate cancer who elected active surveillance with those who underwent immediate surgery accounting for evidence that approximately one-third of men who choose surveillance will eventually undergo treatment. Our findings suggest that men who are closely followed with surveillance may have

Our aim was to assess supervised training and home-based rehabilitation efficacy on balance improvement in ankylosing spondylitis subjects on biologic agents. This was a single-blinded, quasi-randomized parallel study in a single outpatient Rehabilitation Clinic of a tertiary referral center. Subjects with ankylosing spondylitis on biologic agents were assigned either to supervised training and home-based rehabilitation program (rehabilitation group) plus educational-behavioral therapy, or to educational-behavioral therapy alone (educational groups). The same therapist provided therapy. Outcome measures were assessed at baseline (T0), end of treatment (T1) and at 7-month follow-up (T2). Rheumatologic outcomes were Bath Ankylosing Spondylitis Metrology Index, Bath Ankylosing Spondylitis Functional Index and Bath Ankylosing Spondylitis Disease Activity Index. Balance parameters (anterior-posterior oscillation, latero-lateral oscillation, sway area, sway density and sway path) were evaluated by stabilometry in a condition of open and closed eyes. Forty-six subjects (36 M, 10 F) were enrolled. Demographic data and clinical status at baseline were comparable between the two groups (22 rehabilitation group, 20 educational group). Primary outcome was sway density that improved both at T1 (SDy: open eyes p = 0.003, closed eyes p = 0.004) and at T2 (SDx: open eyes p = 0.0015, closed eyes p = 0.032). A trend toward improvement in the rehabilitation group rather than in the educational group emerged for balance parameters, especially those measured with closed eyes (0.004 < p < 0.048 at T1 and 0.004 < p < 0.036 at T2). Supervised training and home exercise lead to balance improvement in people with ankylosing spondylitis. Eyes-closed trials show a more marked trend toward improvement, and this may suggest a

    There are several reports on the correlation between early tumor shrinkage (ETS) or depth of response (DpR) and survival in chemotherapies for colorectal cancer; however, few studies have investigated it in pancreatic cancer. We therefore investigated whether the ETS will predict outcomes in 59 patients with advanced pancreatic cancer treated with FOLFIRINOX therapy. The association of ETS with progression-free survival (PFS) and overall survival (OS) was evaluated but also we addressed to the correlation between outcomes and DpR. ETS was defined as a reduction ≥ 20% of target lesions' diameters measured at 6 to 8 weeks from treatment start. DpR was percentage of maximal tumor shrinkage observed at the nadir diameter compared with baseline. Among 47 evaluable patients for the ETS, 12 (25.5%) patients experienced ETS. The ETS was significantly associated with better PFS (9.0 vs. 4.2 months) as well as OS (24.0 vs. 9.1 months); moreover, the association had a statistically significance for PFS but a strong trend for OS in multivariate analysis. The DpR was statistically significantly but weakly associated with OS. In conclusion, this is the first report that the early response to chemotherapy may predict favorable outcomes in patients with advanced pancreatic cancer treated with FOLFIRINOX therapy.

    Colorectal tumorigenesis is ascribed to the activity of Wnt signaling pathway in a ligand-independent manner mainly through APC and CTNNB1 gene mutations and in a ligand-dependent manner through low expression of Wnt inhibitors such as WNT inhibitory factor 1 (WIF1) and secreted frizzled related protein 1 (SFRP1). In this study we found that WIF1 protein expression was increased and SFRP1 was decreased significantly in CRC tissue versus normal tissue, and high expression of WIF1 was associated with big tumor diameters and deep invasion, and loss of SFRP1 expression was associated with the left lesion site, deep invasion, and high TNM stage. Among the four expression patterns (WIF+/SFRP1+, WIF+/SFRP1−, WIF−/SFRP1+, and WIF−/SFRP1−) only coexpression of WIF1 and SFRP1 (WIF+/SFRP1+) was associated with favorable overall survival, together with low TNM stage, as an independent prognostic factor as shown in a multivariate survival model. The results indicated that WIF1 seemed to play an oncogenic role, while SFRP1 seemed to play an oncosuppressive role although both of them are secreted Wnt antagonists. Coexpression of SFRP1 and WIF1, rather than SFRP1 or WIF1 alone, could be used, together with low TNM stage, as a prognostic predictor of favorable outcomes in CRC. PMID:24949429

    Although acute myeloid leukemia (AML) exhibits diverse responses to chemotherapy, patients harboring the t(8;21) translocation are part of a favorable risk group. However, the reason why this subgroup is more responsive to cytarabine-based therapy has not been elucidated. In the present study, we analyzed expression levels of cytarabine metabolism-related genes in patients diagnosed with AML with or without t(8;21) and investigated their correlation with clinical outcomes after cytarabine-based therapy. Among the 8 genes studied, expression of the concentrative nucleoside transporter 3 (CNT3) gene was significantly higher in t(8;21)-positive patients compared to the others in the test population and the validation cohort (P<0.001 in Mann-Whitney U test; P<0.002 in Pearson's correlation analysis). Additionally, in both multivariate and univariate analyses, t(8;21)-positive patients categorized in a higher CNT3 expression tertile had longer disease-free survival [hazard ratio (HR), 0.117; 95% confidence interval (CI), 0.025-0.557; P=0.008] and overall survival (HR, 0.062; 95% CI, 0.007-0.521; P=0.010) compared to t(8;21)-positive patients in a lower CNT3 expression tertile. Notably, these trends did not occur in t(8;21)-negative patients. Our results demonstrate that CNT3 expression is associated with overall favorable outcomes and is predictive of clinical outcomes in AML patients with t(8;21). This suggests that CNT3 expression can be used to optimize treatment strategies for AML patients.

    Mutations in Toll-like receptor (TLR) and myeloid differentiation primary response 88 (MYD88) genes have been found in chronic lymphocytic leukemia (CLL) at low frequency. We analyzed the incidence, clinicobiological characteristics, and outcome of patients with TLR/MYD88 mutations in 587 CLL patients. Twenty-three patients (3.9%) had mutations, 19 in MYD88 (one with concurrent IRAK1 mutation), 2 TLR2 (one with concomitant TLR6 mutation), 1 IRAK1, and 1 TLR5. No mutations were found in IRAK2 and IRAK4. TLR/MYD88-mutated CLL overexpressed genes of the nuclear factor κB pathway. Patients with TLR/MYD88 mutations were significantly younger (83% age ≤50 years) than those with no mutations. TLR/MYD88 mutations were the most frequent in young patients. Patients with mutated TLR/MYD88 CLL had a higher frequency of mutated IGHV and low expression of CD38 and ZAP-70. Overall survival (OS) was better in TLR/MYD88-mutated than unmutated patients in the whole series (10-year OS, 100% vs 62%; P = .002), and in the subset of patients age ≤50 years (100% vs 70%; P = .02). In addition, relative OS of TLR/MYD88-mutated patients was similar to that in the age- and gender-matched population. In summary, TLR/MYD88 mutations identify a population of young CLL patients with favorable outcome.

    Purpose To assess long-term outcomes of men with favorable-risk prostate cancer in a prospective, active-surveillance program. Methods Curative intervention was recommended for disease reclassification to higher cancer grade or volume on prostate biopsy. Primary outcomes were overall, cancer-specific, and metastasis-free survival. Secondary outcomes were the cumulative incidence of reclassification and curative intervention. Factors associated with grade reclassification and curative intervention were evaluated in a Cox proportional hazards model. Results A total of 1,298 men (median age, 66 years) with a median follow-up of 5 years (range, 0.01 to 18.00 years) contributed 6,766 person-years of follow-up since 1995. Overall, cancer-specific, and metastasis-free survival rates were 93%, 99.9%, and 99.4%, respectively, at 10 years and 69%, 99.9%, and 99.4%, respectively, at 15 years. The cumulative incidence of grade reclassification was 26% at 10 years and was 31% at 15 years; cumulative incidence of curative intervention was 50% at 10 years and was 57% at 15 years. The median treatment-free survival was 8.5 years (range, 0.01 to 18 years). Factors associated with grade reclassification were older age (hazard ratio [HR], 1.03 for each additional year; 95% CI, 1.01 to 1.06), prostate-specific antigen density (HR, 1.21 per 0.1 unit increase; 95% CI, 1.12 to 1.46), and greater number of positive biopsy cores (HR, 1.47 for each additional positive core; 95% CI, 1.26 to 1.69). Factors associated with intervention were prostate-specific antigen density (HR, 1.38 per 0.1 unit increase; 95% CI, 1.22 to 1.56) and a greater number of positive biopsy cores (HR, 1.35 for one additional positive core; 95% CI, 1.19 to 1.53). Conclusion Men with favorable-risk prostate cancer should be informed of the low likelihood of harm from their diagnosis and should be encouraged to consider surveillance rather than curative intervention.

    For patients with metastatic breast cancer, we previously described that increased EZH2 expression levels were associated with an adverse outcome to tamoxifen therapy. Main objective of the present study is to investigate miR-26a and miR-101 levels, which both target EZH2, for their association with molecular pathways and with efficacy of tamoxifen as first-line monotherapy for metastatic breast cancer. Expression levels were measured using quantitative Real-Time Polymerase Chain Reaction (qRT-PCR) in primary breast cancer specimens of 235 estrogen receptor-α (ER)-positive patients. Pathway analysis was performed on microarray data available for 65 of these tumors. Logistic regression and Cox uni- and multivariate analysis were performed to relate expression levels with clinical benefit and time to progression (TTP). Increasing levels of miR-26a were significantly (P < 0.005) associated with both clinical benefit and prolonged TTP, whereas miR-101 was not. Cell cycle regulation and CCNE1 and CDC2 were the only significant overlapping pathway and genes differentially expressed between tumors with high and low levels of miR-26a and EZH2, respectively. In addition, increasing mRNA levels of CCNE1 (P < 0.05) and CDC2 (P < 0.001) were related to poor outcome. Multivariate analysis revealed miR-26a and CDC2 as an optimal set of markers associated with outcome on tamoxifen therapy, independently of traditional predictive factors. To summarize, only miR-26a levels are related with treatment outcome. Cell cycle regulation is the only overlapping pathway linked to miR-26a and EZH2 levels. Low mRNA levels of EZH2, CCNE1, and CDC2, and high levels of miR-26a are associated with favorable outcome on tamoxifen.

    Large cohort studies suggest that high convective volumes associated with online hemodiafiltration may reduce the risk of mortality/morbidity compared to optimal high-flux hemodialysis. By contrast, intradialytic tolerance is not well studied. The aim of the FRENCHIE (French Convective versus Hemodialysis in Elderly) study was to compare high-flux hemodialysis and online hemodiafiltration in terms of intradialytic tolerance. In this prospective, open-label randomized controlled trial, 381 elderly chronic hemodialysis patients (over age 65) were randomly assigned in a one-to-one ratio to either high-flux hemodialysis or online hemodiafiltration. The primary outcome was intradialytic tolerance (day 30-day 120). Secondary outcomes included health-related quality of life, cardiovascular risk biomarkers, morbidity, and mortality. During the observational period for intradialytic tolerance, 85% and 84% of patients in high-flux hemodialysis and online hemodiafiltration arms, respectively, experienced at least one adverse event without significant difference between groups. As exploratory analysis, intradialytic tolerance was also studied, considering the sessions as a statistical unit according to treatment actually received. Over a total of 11,981 sessions, 2,935 were complicated by the occurrence of at least one adverse event, with a significantly lower occurrence in online hemodiafiltration with fewer episodes of intradialytic symptomatic hypotension and muscle cramps. By contrast, health-related quality of life, morbidity, and mortality were not different in both groups. An improvement in the control of metabolic bone disease biomarkers and β2-microglobulin level without change in serum albumin concentration was observed with online hemodiafiltration. Thus, overall outcomes favor online hemodiafiltration over high-flux hemodialysis in the elderly.

    We present a systematic review of the current literature regarding the use of the 2 most common surgical treatments for lesions of the long head of the biceps brachii, tenotomy or tenodesis. Currently, there is no consensus management in the literature because most studies lack high levels of evidence. PubMed was systematically reviewed for eligible articles relating to biceps tenotomy or tenodesis. Level I to IV evidence and English-language studies reporting on the clinical outcomes of these 2 procedures were included. The primary clinical outcome measurements for each study were determined and were normalized and reported as the percentage of "excellent/good" versus "poor" results based on criteria laid out in each study. Sixteen studies met the inclusion criteria. All articles reviewed were of Level IV evidence, except for one Level II prospective cohort study.(10) All studies, a total of 433 tenodesis procedures resulted in an excellent/good outcome in 74% of patients, with an 8% rate of cosmetic deformity. A total of 699 tenotomy procedures resulted in an excellent/good outcome in 77% of patients, with a 43% occurrence of cosmetic deformity. Postoperative bicipital pain was found in 43 of 226 cases (19%) of tenotomy and 18 of 74 cases (24%) of tenodesis. The 4 studies that compared the procedures directly did not show any significant clinical differences between the groups other than a cosmetic deformity being present more frequently after tenotomy. Tenotomy and tenodesis have comparably favorable results in the literature, with the only major difference being a higher incidence of cosmetic deformity with biceps tenotomy. However, there is currently no consensus regarding the use of tenotomy versus tenodesis for the treatment of lesions of the long head of the biceps brachii. The lack of prospective, randomized trials limits our ability to recommend 1 technique over the other. There is a great need for controlled trials to investigate the differences between

    Secondary hyperparathyroidism (SHPT) is a common complication of end-stage renal disease and is one of the most prominent causes of a markedly increased risk of death and cardiovascular disease in this patient population. Cinacalcet hydrochloride is a new option for the treatment of SHPT, and the efficacy and effectiveness to lower parathyroid hormone levels and to improve control of mineral metabolism, even in patients with severe disease, has been well established in many clinical trials and observational studies. Currently, the focus has moved to the impact of cinacalcet on hard clinical outcomes, and two randomized controlled trials, ADVANCE and EVOLVE, have been performed to assess the effects of cinacalcet on cardiovascular calcification and the risk of cardiovascular events and mortality, respectively. Although the primary analysis of both trials did not find significant effects of cinacalcet, the benefit of cinacalcet was suggested in the subanalyses in which the potential problems of the trials were taken into account. These positive results are consistent with experimental studies showing favorable effects of cinacalcet on bone metabolism and vascular calcification, providing plausibility to support the beneficial effects of cinacalcet. Definitive evidence is, however, still lacking, and further efforts should be made to establish the optimal role of cinacalcet in the treatment of SHPT.

    Congenital pulmonary airway malformations (CPAMs) are rare congenital lung lesions often diagnosed by prenatal ultrasound. High-risk cases can result in hydrops and prenatal or postnatal demise. Antenatal betamethasone has resulted in improved survival but it is unclear how to manage patients who do not respond to a single course. We present a bi-institutional retrospective review of patients treated with multiple courses of prenatal steroids for high-risk CPAMs between 2007 and 2013. Nine patients met inclusion criteria. All but one either had an increased CPAM volume ratio (CVR) or number of fluid-containing compartments involved after a single course of antenatal betamethasone, prompting additional courses. Four patients stabilized, three improved and two progressed after the second course. The two cases with disease progression underwent an in utero resection. There were one in utero fetal demise and two deaths within the delivery room. Both fetuses that underwent a fetal resection died. All but one mother who delivered a viable fetus had complications of pregnancy. Multiple courses of antenatal betamethasone for high-risk fetal CPAMs often result in favorable short-term outcomes without the need for open fetal resection. Pregnancy complications are common and women within this cohort should be monitored closely. Copyright © 2015 Elsevier Inc. All rights reserved.

    Many studies have assessed the volume-outcome relationship in cancer patients, but most focused on better outcomes in higher volume groups rather than identifying a specific threshold that could assist in clinical decision-making for achieving the best outcomes. The current study suggests an optimal volume for achieving good outcome, as an extension of previous studies on the volume-outcome relationship in stomach cancer patients. We used National Health Insurance Service (NHIS) Sampling Cohort data during 2004-2013, comprising healthcare claims for 2550 patients with newly diagnosed stomach cancer. We conducted survival analyses adopting the Cox proportional hazard model to investigate the association of three threshold values for surgical volume of stomach cancer patients for cancer-specific mortality using the Youden index. Overall, 17.10% of patients died due to cancer during the study period. The risk of mortality among patients who received surgical treatment gradually decreased with increasing surgical volume at the hospital, while the risk of mortality increased again in "high" surgical volume hospitals, resulting in a j-shaped curve (mid-low = hazard ratio (HR) 0.773, 95% confidence interval (CI) 0.608-0.983; mid-high = HR 0.541, 95% CI 0.372-0.788; high = HR 0.659, 95% CI 0.473-0.917; ref = low). These associations were especially significant in regions with unsubstantial surgical volumes and less severe cases. The optimal surgical volume threshold was about 727.3 surgical cases for stomach cancer per hospital over the 1-year study period in South Korea. However, such positive effects decreased after exceeding a certain volume of surgeries.

    Few studies have conducted follow-up investigations of the clinical course in HCV-related cirrhotic patients who achieved a sustained virological response (SVR) with pegylated interferon plus ribavirin treatment (PegIFN + RBV). We investigated the clinical course and laboratory data in a prospective cohort study enrolling HCV-related cirrhotic patients who received PegIFN + RBV between August 2008 and July 2013 in China. Complete blood counts, liver function tests, and HCV-RNA were serially examined. Liver-related complications were recorded. To detect hepatocellular carcinoma (HCC), alpha-fetoprotein assays, and ultrasound scans were repeated at 6-month intervals. Twenty-five patients were enrolled, including 8 patients with decompensation events before treatment. Eighteen patients achieved SVR with a mean follow-up period of 25.78 months. During the follow-up period, only one patient exhibited HCV-RNA positivity and no decompensation events were detected, but 4 patients developed HCC after SVR. APRI decreased more in patients with SVR than in patients with non-SVR (median, −1.33 versus 0.86, P < 0.001). The albumin levels and platelet counts significantly increased during the follow-up period after SVR (44.27 ± 4.09 versus 42.63 ± 4.37, P = 0.037 and 173.89 ± 87.36 versus 160.11 ± 77.97, P = 0.047). These data indicated that HCV-related cirrhotic patients with SVR after PegIFN + RBV may have a favorable clinical course and improvements in laboratory data. Moreover, HCC should be monitored.

    Alpha thalassemia major (ATM) is often fatal in utero due to severe hydrops fetalis. Although in utero transfusions (IUTs) are increasingly used to allow fetal survival in ATM, prenatal and postnatal outcomes are not well described. We retrospectively reviewed cases of ATM at our institution treated with consecutive IUT. Clinical records were reviewed for transfusion history, neurodevelopmental outcomes, anatomic abnormalities, survival to hematopoietic cell transplantation, and transfusion independence. A systematic review was performed, and additional reported cases are discussed. Three patients who underwent IUT for ATM were identified, and review of the literature revealed 17 reported cases. Of patients who received IUT, reported neurodevelopmental deficits occurred in 29% (4/14) and anatomic abnormalities in 55% (11/20). Four patients eventually underwent successful hematopoietic cell transplantation. Transfusion volumes were less than suggested guidelines for other causes of fetal anemia in 91.7% of the transfusions. This series demonstrates the potential for achieving full fetal development with normal neurologic outcomes in those affected by ATM. It provides support for continued patient and provider education about current benefits and risks of active prenatal therapy for fetuses with ATM, as well as continued research to optimize therapeutic strategies such as in utero transplantation. © 2016 John Wiley & Sons, Ltd. © 2016 John Wiley & Sons, Ltd.

    Internet and mobile devices are widely used and provide alternative approaches for promoting healthy lifestyles, yet less information is available describing outcomes of these approaches when used with young African American (AA) women at risk for developing hypertension. In this study, we evaluated a Web-based, culturally relevant lifestyle change intervention targeting AA women (referred to as the eHealth study). African American women, aged 18 to 45 years, with untreated prehypertension and Internet access were eligible for a 12-week study that incorporated social cognitive theory strategies. Participants were randomized to (1) lifestyle physical activity (PA) or (2) Dietary Approaches to Stop Hypertension (DASH) online education modules. The 14 DASH and 12 PA participant attributes were similar at baseline. The DASH participants had a significant change in total DASH score (P = .001) and large effect sizes for DASH components (vegetables, 0.84; nonfat dairy, 0.71; fruit, 0.62). The PA participants had a favorable change (+39%) in pedometer steps (P = .055). With respect to weight change, a large effect size was observed for PA (0.84) and smaller for DASH participants (0.18). Seventy-one percent of DASH and 48% of PA participants completed program activities, corresponding to a moderate difference in program engagement between groups (d = 0.58). Our eHealth platform provides an alternative approach for reaching young AA women and was successful with respect to improving PA and dietary behaviors. Furthermore, the eHealth approach has the potential as a powerful program for changing health behaviors for other at-risk populations.

    Purpose. To review the clinical outcome of patients with hypertensive uveitis. Methods. Retrospective review of uveitis patients with elevated intraocular pressure (IOP) > 25 mmHg and >1-year follow-up. Data are uveitis type, etiology, viral (VU) and nonviral uveitis (NVU), IOP, and medical and/or surgical treatment. Results. In 61 patients, IOP values are first 32.9 mmHg (SD: 9.0), highest 36.6 mmHg (SD: 9.9), 3 months after the first episode 19.54 mmHg (SD: 9.16), and end of follow-up 15.5 mmHg (SD: 6.24). Patients with VU (n = 25) were older (50.6 y/35.7 y, p = 0.014) and had more unilateral disease (100%/72.22%  p = 0.004) than those with NVU (n = 36). Thirty patients (49.2%) had an elevated IOP before topical corticosteroid treatment. Patients with viral uveitis might have higher first elevated IOP (36.0/27.5 mmHg, p = 0,008) and maximal IOP (40.28/34.06 mmHg, p = 0.0148) but this was not significant when limited to the measurements before the use of topical corticosteroids (p = 0.260 and 0.160). Glaucoma occurred in 15 patients (24.59%) and was suspected in 11 (18.03%) without difference in viral and nonviral groups (p = 0.774). Conclusion. Patients with VU were older and had more unilateral hypertensive uveitis. Glaucoma frequently complicates hypertensive uveitis. Half of the patients had an elevated IOP before topical corticosteroid treatment. PMID:26504598

    The autoimmune lymphoproliferative syndrome (ALPS) is a disorder of abnormal lymphocyte survival caused by the dysregulation of the Fas apoptotic pathway. The Fas gene is expressed at the maternal-fetal interface and is involved in the regulation of immune response and implantation. Altered Fas expression may result in altered apoptosis and, ultimately, affect both the immune response and implantation; it is in fact associated with recurrent pregnancy loss, preterm premature rupture of membranes and pre-eclampsia. Currently, there are over 500 cases of ALPS reported worldwide from various racial and ethnic backgrounds. Up to date, the published work contains no specific reports on pregnancy outcome in women affected by ALPS. We present a case of full-term uneventful pregnancy in a patient affected by ALPS. A specific clinical follow-up in a pregnant woman with primary immunologic disease is suggested.

    Clinical outcome prediction, as strong implications for health service delivery of clinical treatment processes (CTPs), is important for both patients and healthcare providers. Prior studies typically use a priori knowledge, such as demographics or patient physical factors, to estimate clinical outcomes at early stages of CTPs (e.g., admission). They lack the ability to deal with temporal evolution of CTPs. In addition, most of the existing studies employ data mining or machine learning methods to generate a prediction model for a specific type of clinical outcome, however, a mathematical model that predicts multiple clinical outcomes simultaneously, has not yet been established. In this study, a hybrid approach is proposed to provide a continuous predictive monitoring service on multiple clinical outcomes. More specifically, a probabilistic topic model is applied to discover underlying treatment patterns of CTPs from electronic medical records. Then, the learned treatment patterns, as low-dimensional features of CTPs, are exploited for clinical outcome prediction across various stages of CTPs based on multi-label classification. The proposal is evaluated to predict three typical classes of clinical outcomes, i.e., length of stay, readmission time, and the type of discharge, using 3492 pieces of patients' medical records of the unstable angina CTP, extracted from a Chinese hospital. The stable model was characterized by 84.9% accuracy and 6.4% hamming-loss with 3 latent treatment patterns discovered from data, which outperforms the benchmark multi-label classification algorithms for clinical outcome prediction. Our study indicates the proposed approach can potentially improve the quality of clinical outcome prediction, and assist physicians to understand the patient conditions, treatment inventions, and clinical outcomes in an integrated view.

    Purpose: There are no published reports on the optimal management and survival rates of children with Wilms tumor (WT) and peritoneal implants (PIs). Methods and Materials: Among favorable histology WT patients enrolled in the National Wilms Tumor Study (NWTS)-4 and NWTS-5, 57 children had PIs at the time of nephrectomy. The median age was 3 years 5 months (range, 3 months to 14 years). The majority of children (42 of 57 [74%)] had Stage III tumors; 15 had Stage IV disease. All patients received multimodality therapy. Of 56 children who underwent primary surgery, 48 (84%) had gross total resection of all tumors. All patients received 3-drug chemotherapy with vincristine, dactinomycin, and doxorubicin. Whole-abdomen radiotherapy (RT) was used in 47 patients (82%), and in 50 patients (88%) the RT dose was 10.5 Gy. Results: After a median follow-up of 7.5 years, the overall abdominal and systemic tumor control rates were 97% and 93%, respectively. A comparative analysis between children with PIs and those without PIs showed no significant differences in the clinical characteristics between the two groups. The 5-year event-free survival rates with and without PIs were 90% (95% confidence interval, 78-96%) and 83% (95% confidence interval, 81-85%) respectively (p = 0.20). Conclusions: Multimodality therapy with surgery, whole-abdomen RT, and three-drug chemotherapy delivered according to the NWTS-4 and -5 protocols resulted in excellent abdominal and systemic tumor control rates. All children should be monitored in long-term surveillance programs for the early detection and management of therapy-related toxicities.

    An 80-year-old Japanese woman with wet cough and dyspnea was diagnosed with pneumonia at a clinic. Antibiotics did not improve her symptoms; therefore, she was referred to our hospital one month after symptom onset. Chest radiograph findings revealed complete collapse of the left lung. Bronchoscopy showed white mucus plug in the left main bronchus, which could not be removed. She was initially treated with bromhexine. Subsequently, culture results of the mucus plug specimen obtained during bronchoscopy yielded Schizophyllum commune. After three weeks, improvement of the collapsed lung was observed on chest radiograph.

    Multisystemic therapy (MST) is an evidence-based treatment originally developed for youth with serious antisocial behavior who are at high risk for out-of-home placement and their families; and subsequently adapted to address other challenging clinical problems experience by youths and their families. The social-ecological theoretical framework of MST is presented as well as its home-based model of treatment delivery, defining clinical intervention strategies, and ongoing quality assurance/quality improvement system. With more than 100 peer-reviewed outcome and implementation journal articles published as of January 2016, the majority by independent investigators, MST is one of the most extensively evaluated family based treatments. Outcome research has yielded almost uniformly favorable results for youths and families, and implementation research has demonstrated the importance of treatment and program fidelity in achieving such outcomes.

    Cervical neuroblastoma, a disease primarily of infants, has a favorable prognosis. Eleven patients are reported. Clinical presentations (other than mass) included stridor and swallowing problems. Masses when felt were commonly mistaken for infectious adenitis. Imaging studies (US, CT, MRI) showed solid masses with vascular displacement and narrowing; intraspinal extension was absent though extension into the adjacent sites of mediastinum and skull occurred. Horner syndrome was seen in five patients with accompanying heterochromia iridis in one. Five tumors had calcification. A high index of suspicion will lead to biopsy and less delay in diagnosis once a mass is felt or imaged.

    The appropriate duration of cardiopulmonary resuscitation (CPR) for pediatric out-of-hospital cardiac arrests (OHCAs) remains unclear and may differ based on initial rhythm. We aimed to determine the relationship between the duration of prehospital CPR by emergency medical services (EMS) personnel and post-OHCA outcomes. We analyzed the records of 12 877 pediatric patients who experienced OHCAs (<18 years of age). Data were recorded in a nationwide Japanese database between 2005 and 2012. Study end points were 30-day survival and 30-day survival with favorable neurological outcomes (Cerebral Performance Category [CPC] scale 1-2). Prehospital EMS-initiated CPR duration was defined as the time from CPR initiation by EMS personnel to prehospital return of spontaneous circulation (ROSC) or to hospital arrival when prehospital ROSC was not achieved during prehospital CPR efforts. The rates of 30-day survival and 30-day CPC 1 to 2 were 9.1% (n=1167) and 2.5% (n=325), respectively. Prehospital EMS-initiated CPR duration was significantly and inversely associated with 30-day outcomes (adjusted odds ratio for 1-minute increments: 0.94, 95% confidence interval: 0.93-0.95 for survival; adjusted odds ratio: 0.90, 95% confidence interval: 0.88-0.92 for CPC 1-2). The duration of prehospital EMS-initiated CPR, beyond which the chance for favorable outcomes diminished to <1%, was 42 minutes for each key outcome, 30-day survival, and 30-day survival with CPC 1 to 2. When categorized by initial rhythm, the prehospital EMS-initiated CPR durations beyond which the chance for 30-day survival with CPC 1 to 2 diminished to <1% were 39 minutes for shockable rhythms, 42 minutes for pulseless electric activity, and 46 minutes for asystole, respectively. In patients with bystander-initiated CPR, the prehospital CPR duration, beyond which the chance for favorable outcome diminished to <1%, was 46 minutes from call receipt. Prehospital EMS-initiated CPR duration for pediatric OHCAs was

    Type 2 diabetes is known to increase the risk and progression of certain types of cancer. Metformin treatment of diabetic patients is reported to have beneficial effects on some cancers. We evaluated the clinical outcome of diabetic patients with differentiated thyroid cancer (DTC) according to metformin treatment. We reviewed 943 patients diagnosed with DTC after total thyroidectomy between 1995 and 2005 in a tertiary hospital. The study involved 60 diabetic patients and 210 control patients matched for age, sex, body mass index (BMI), and tumor size. There were no differences in the clinicopathological features and disease-free survival (DFS) between diabetic patients and the control group over 8.9 years of follow-up. Of the diabetic patients with DTC, 35 patients (58%) were treated with metformin. There were no differences in age, sex, BMI, tumor size, antidiabetic medication, glycated hemoglobin, or C-peptide levels in metformin and nonmetformin groups. However, cervical lymph node (LN) metastasis was more prevalent in the metformin group than in the nonmetformin group (OR 3.52, p = 0.035). Among diabetic patients with cervical LN metastasis of DTC, the metformin subgroup (17.1 years) was associated with longer DFS than the nonmetformin subgroup (8.6 years) (HR 0.16, p = 0.021); metformin treatment was also associated with longer DFS in this subgroup in multivariate analysis after adjusting age, BMI, duration of diabetes, presence of tumor at resection margin, and serum thyroglobulin level at ablation (HR 0.03, p = 0.035). Metformin treatment is associated with low recurrence in diabetic patients with cervical LN metastasis of DTC.

    The application of a protocol for the initial assessment of medical care outcomes of geriatric depression management in four multispecialty group practice clinics is described. The clinical findings of this study are limited, but the protocol for the assessment of depression outcomes was found to be feasible, practical and acceptable in all four clinics. The success of the study has positive implications both for improving management of depressed clinic patients and for adapting this quality assurance approach to other health conditions and care settings.

    The global targets for tuberculosis (TB) control set by the World Health Assembly (WHA) in 1991 were detection of at least 70% and cure of at least 85% of new sputum smear-positive TB cases by 2000, later revised to 2005. The DOTS strategy was introduced in the mid-1990s, and later became the cornerstone of the Stop TB Strategy, which was launched along with the Global Plan to Stop TB 2006-2015 in 2006. The Global Plan sets out how and to what extent the Stop TB Strategy should be implemented between 2006 and 2015 to achieve the TB-related Millennium Development Goal (MDG) to halt and reverse the incidence of TB by 2015 and the Stop TB Partnership targets to reduce TB prevalence and death rates to 50% of 1990 levels by 2015, and to eliminate TB as a public health concern by 2050. Treatment success and case detection rates are outcome indicators used to measure the effectiveness of TB control along with the impact indicators incidence, prevalence and death rates. Globally, the rate of treatment success for smear-positive cases treated exceeded the WHA global target of 85% for the first time in 2007. This review focuses on articles related to treatment outcome in TB published in the International Journal of Tuberculosis and Lung Disease in 2009.

    As Medicaid expands in scope and influence, it is evolving toward being a “purchaser” of quality health care. This commentary discusses measurement and incentivization of clinical outcomes in Medicaid. Advantages and disadvantages of outcome versus process measures are discussed. Distinctions are drawn between the roles of Medicare and Medicaid, including the implications of the growth in Medicaid managed care. Medicaid's influence is particularly notable for obstetric, pediatric, newborn, and long-term care. We provide data on 3 Medicaid outcomes: potentially preventable hospital admissions, readmissions, and complications. The commentary concludes with suggestions for choosing and implementing outcome-oriented value-based purchasing initiatives in Medicaid. PMID:26945295

    Outcome measurement is crucial to assuring high-quality patient services and improving the quality of services provided by prosthetists. This article summarizes recent evidence on the measurement properties of outcome measures, and updates previously published summaries of outcome instruments. The review focuses on measures of mobility, functional status, quality of life, and patient satisfaction, and includes both performance-based and patient-reported outcomes. Amputation-specific and general measures that are suitable for patients served by prosthetists are discussed. It is encouraging that responsiveness of measures is often reported, as this information is needed to improve clinical utility.

    Periodic evaluation of neurointensive care (NIC) is important. There is a risk that quality of daily care declines and there may also be unrecognized changes in patient characteristics and management. The aim of this work was to investigate the characteristics and outcome for traumatic brain injury (TBI) patients in the period 2008-2009 in comparison with 1996-1997 and to some extent also with earlier periods. TBI patients 16-79 years old admitted from 2008 to 2009 were selected for the study. Glasgow Coma Scale Motor score at admission (GCS M), radiology, surgery, and outcome (Glasgow Outcome Extended Scale) were collected from Uppsala Traumatic Brain Injury Register. The study included 148 patients (mean age, 45 years). Patients >60 years old increased from 16 % 1996-1997 to 30 % 2008-2009 (p < 0.01). The proportion of GCS M 4-6 were similar, 92 vs. 93 % (NS). In 1996-1997 patients, 73 % had diffuse injury (Marshall classification) compared to 77 % for the 2008-2009 period (NS). More patients underwent surgery during 2008-2009 (43 %) compared to 1996-1997 (32 %, p < 0.05). Good recovery increased and mortality decreased substantially from 1980-1981 to 1987-1988 and to 1996-1997, but then the results were unchanged in the 2008-2009 period, with 73 % favorable outcome and 11 % mortality. Mortality increased in GCS M 6-4, from 2.8 % in 1996-1997 to 10 % in 2008-2009 (p < 0.05); most of the patients that died had aggravating factors, e.g., high age, malignancy. A large-proportion favorable outcome was maintained despite that patients >60 years with poorer prognosis doubled, indicating that the quality of NIC has increased or at least is unchanged. More surgery may have contributed to maintaining the large proportion of favorable outcome. For future improvements, more knowledge about TBI management in the elderly is required.

    The effects of hyperoxia on the neurological outcomes of patients with severe traumatic brain injury (TBI) are still controversial. We examined whether the partial pressure of arterial oxygen (PaO2) and hyperoxia were associated with neurological outcomes and survival by conducting post-hoc analyses of the Brain Hypothermia (B-HYPO) study, a multi-center randomized controlled trial of mild therapeutic hypothermia for severe TBI. The differences in PaO2 and PaO2/fraction of inspiratory oxygen (P/F) ratio on the 1st day of admission were compared between patients with favorable (n = 64) and unfavorable (n = 65) neurological outcomes and between survivors (n = 90) and deceased patients (n = 39). PaO2 and the P/F ratio were significantly greater in patients with favorable outcomes than in patients with unfavorable neurological outcomes (PaO2: 252 ± 122 vs. 202 ± 87 mm Hg, respectively, p = 0.008; P/F ratio: 455 ± 171 vs. 389 ± 155, respectively, p = 0.022) and in survivors than in deceased patients (PaO2: 242 ± 117 vs. 193 ± 75 mm Hg, respectively, p = 0.005; P/F ratio: 445 ± 171 vs. 370 ± 141, respectively, p = 0.018). Similar tendencies were observed in subgroup analyses in patients with fever control and therapeutic hypothermia, and in patients with an evacuated mass or other lesions (unevacuated lesions). PaO2 was independently associated with survival (odds ratio 1.008, p = 0.037). These results suggested that early-stage hyperoxia might be associated with favorable neurological outcomes and survival following severe TBI.

    Necrotizing fasciitis is a rare severe soft tissue infection that has historically been associated with high mortality. We sought to evaluate our experience with necrotizing fasciitis focusing on outcomes based on timing of operative intervention. Our study hypothesis was that delays in surgical management would negatively impact outcomes. Fifty-four patients were identified for a retrospective chart review from January 2008 to January 2011. Data analysis included demographics, admission laboratory values, imaging results, examination findings, timing and nature of operations, length of stay (LOS), and outcomes. Surgical intervention in 12 hours or more was considered a delay in care. Our study cohort was high risk based on a high prevalence of intravenous drug abuse, diabetes mellitus, hypertension, and end-stage liver disease. The average time to surgical intervention was 18±25 hours and the overall mortality rate was 16 per cent. A delay to surgery did not impact mortality or the number of débridements and LOS. Mortality was high, 45 per cent, in patients requiring amputation. We observed a high-risk population managed with aggressive surgical care for necrotizing fasciitis. Our mortality was low compared with historical data and surgical delays did not impact outcomes. Those patients requiring amputation had worse outcomes.

    Ovarian clear cell carcinoma (CCC) is generally associated with chemoresistance and poor clinical outcome, even with early diagnosis; whereas high-grade serous carcinomas (SCs) and endometrioid carcinomas (ECs) are commonly chemosensitive at advanced stages. Although an integrated genomic analysis of SC has been performed, conclusive views on copy number and expression profiles for CCC are still limited. In this study, we performed single nucleotide polymorphism analysis with 57 epithelial ovarian cancers (31 CCCs, 14 SCs, and 12 ECs) and microarray expression analysis with 55 cancers (25 CCCs, 16 SCs, and 14 ECs). We then evaluated PIK3CA mutations and ARID1A expression in CCCs. SNP array analysis classified 13% of CCCs into a cluster with high frequency and focal range of copy number alterations (CNAs), significantly lower than for SCs (93%, P < 0.01) and ECs (50%, P = 0.017). The ratio of whole-arm to all CNAs was higher in CCCs (46.9%) than SCs (21.7%; P < 0.0001). SCs with loss of heterozygosity (LOH) of BRCA1 (85%) also had LOH of NF1 and TP53, and LOH of BRCA2 (62%) coexisted with LOH of RB1 and TP53. Microarray analysis classified CCCs into three clusters. One cluster (CCC-2, n = 10) showed more favorable prognosis than the CCC-1 and CCC-3 clusters (P = 0.041). Coexistent alterations of PIK3CA and ARID1A were more common in CCC-1 and CCC-3 (7/11, 64%) than in CCC-2 (0/10, 0%; P < 0.01). Being in cluster CCC-2 was an independent favorable prognostic factor in CCC. In conclusion, CCC was characterized by a high ratio of whole-arm CNAs; whereas CNAs in SC were mainly focal, but preferentially caused LOH of well-known tumor suppressor genes. As such, expression profiles might be useful for sub-classification of CCC, and might provide useful information on prognosis. PMID:26043110

    To test the efficacy of a strategy based on CT imaging and clinical characteristics on lateralizing origin of excess aldosterone secretion in primary aldosteronism. Consecutive patients with diagnosed primary hyperaldosteronism from June 2006 to July 2012 in our center underwent adrenal surgeries without pre-operational adrenal venous sampling (AVS) if all the three criteria were met: (1) round- or oval-shaped occupational lesion of low density after contrast enhancement with diameter >1 cm on CT scan was located in one adrenal gland; (2) unequivocally normal contralateral adrenal gland; (3) serum potassium level lower than 3.5 mmol/L. Subjects who had received operation were taken into analysis and follow-ups. One hundred and twenty-five patients fulfilled the criteria and were recruited into our research. One hundred and twenty-two operated patients (97.6%) experienced complete resolution of hypokalemia as well as resolution or improvement in hypertension with reduction in antihypertensive medication, while 3 patients (2.4%) failed to obtain normal kalemia and continued on spironolactone therapy. At a median of 65-month (range 21-93) follow-up of these 122 subjects, 27 patients dropped out (22.1%). The 95 responding patients reported no episodes of paralysis or confirmed hypokalemia or any supplementation of potassium. Multivariate linear correlation analysis showed that plasma potassium level was correlated inversely with tumor diameter (r = -0.258, 95% CI -0.076, -0.514, p = 0.037) and basal plasma aldosterone level (r = -0.251, 95% CI -0.040, -0.464, p = 0.042). Most patients with typical unilateral adrenal macroadenomas, normal contralateral glands and hypokalemia could attain favorable surgical therapeutic outcomes without pre-operational AVS lateralization.

    In children with localized Ewing sarcoma (ES), addition of ifosfamide and etoposide to cyclophosphamide, doxorubicin, and vincristine (VDC/IE) improved 5-year overall survival (OS) to 70%-80%. Prior to delivery of VDC/IE in adults, 5-year OS was <50%. We reviewed our institutional outcomes for adults with ES who received VDC/IE-based treatment. Between 1997-2013, 67 adults with localized ES were treated with curative intent. Local recurrence-free survival (LRFS), progression-free survival (PFS), and OS were determined using Kaplan-Meier method; comparisons were assessed with log-rank. Proportional hazard models were used to determine predictive factors. All patients received VDC/IE (median 14 cycles.) Local therapy was surgery for 33, radiation therapy for 17, or both for 17. Median follow-up for living patients was 5.2 years. Six patients had disease progression on therapy. Site of first failure was local for three, local and distant for two, and distant for ten. Five-year LRFS was 91%; 5-year LRFS was 96% for nonpelvic disease and 64% for pelvic disease (p = .003). Five-year PFS was 66%, and 5-year OS was 79%. On multivariate analysis, pelvic site had a 3.3 times increased risk of progression (p = .01). Survival for adults with localized ES treated with VDC/IE-based multimodality therapy appears to be better than historical data and similar to excellent outcomes in children. Pelvic site of disease remains a predictor of worse outcome. Given the paucity of literature for adult ES, these data help validate VDC/IE-based therapy as an appropriate treatment approach for this rare disease in adults. The Oncologist 2017;22:1-6 IMPLICATIONS FOR PRACTICE: Ewing sarcoma (ES) is rare in adults. Treatment approaches for adults have been extrapolated from the pediatric experience, and there is a sense that adults fare less well than children. We reviewed treatment outcomes in adults with localized ES treated with cyclophosphamide, doxorubicin, and vincristine in

    Prenatal diagnosis of pulmonary arteriovenous malformations (PAVM), caused by abnormal communications between pulmonary arteries and pulmonary veins, is rarely described. We report a case of a PAVM between the right pulmonary artery and the left atrium, referred to our prenatal unit at 22 + 1 weeks of gestation, with severe cardiomegaly, dilation of the right pulmonary artery and a right pulmonary vein and retrograde flow in the ductus arteriosus. The fistula was located in the right lung and showed a broad, disturbed flow at color Doppler with high velocity and low pulsatility. The fetus was monitored weekly and cardiac function remained sufficient until 36 + 1 weeks of gestation, when increasing cardiomegaly prompted delivery by cesarean section. The newborn was transferred to the neonatal intensive care unit, intubated and the fistula was surgically removed. The boy could be discharged at the 43rd day of life and showed an uneventful course until the last follow-up at the age of 4 years, with no residual mental or physical handicaps and a normal cardiac function. Despite adverse outcomes described in previously reported cases of large PAVM complicated by severe cardiomegaly at midtrimester scan, our case had a good outcome. © 2013 S. Karger AG, Basel.

    Purpose: To report the outcome of patients treated at the University of Florida who developed meningiomas after radiation to the central nervous system (CNS) for childhood cancer. Methods and Materials: We retrospectively identified 10 patients aged {<=}19 years who received radiotherapy to sites in the craniospinal axis and subsequently developed a meningioma. We report the histology of the radiation-induced meningioma, treatment received, and ultimate outcome among this cohort of patients. Results: Meningioma was diagnosed at a median of 23.5 years after completion of the primary radiation. Fifty percent of second meningiomas were World Health Organization Grade 2 (atypical) or higher. All cases were managed with a single modality: resection alone (n = 7), fractionated radiotherapy (n = 2), and stereotactic radiosurgery (n = 1). The actuarial event-free survival and overall survival rate at 5 years after treatment for a radiation-induced meningioma was 89%. Three patients who underwent resection for retreatment experienced a Grade 3 toxicity. Conclusions: Radiation-induced meningiomas after treatment of pediatric CNS tumors are effectively managed with single-modality therapy. Such late-effect data inform the overall therapeutic ratio and support the continued role of selective irradiation in managing pediatric CNS malignancies.

    DEFUSE 2 demonstrated that patients with magnetic resonance imaging mismatch had a favorable clinical response to tissue reperfusion assessed by magnetic resonance imaging. This study reports the endovascular results and correlates angiographic reperfusion with clinical and imaging outcomes. Prospectively enrolled ischemic stroke patients underwent baseline magnetic resonance imaging and started endovascular therapy within 12 h of onset. Patients were classified as either target mismatch or no target mismatch using magnetic resonance imaging. The pre- and postprocedure angiogram was evaluated to determine thrombolysis in cerebral infarction scores. Favorable clinical response was determined at day 30, and good functional outcome was defined as a modified Rankin Scale 0-2 at day 90. One-hundred patients had attempted endovascular treatment. At procedure end, 23% were thrombolysis in cerebral infarction 0-1, 31% thrombolysis in cerebral infarction 2A, 28% thrombolysis in cerebral infarction 2B, and 18% thrombolysis in cerebral infarction 3. More favorable thrombolysis in cerebral infarction-reperfusion scores were associated with greater magnetic resonance imaging reperfusion (P<0·001). thrombolysis in cerebral infarction scores correlated with 30-day favorable clinical response (P=0·041) and 90-day modified Rankin Scale 0-2 (P=0·008). These correlations were significant for target mismatch patients at 30 days (P=0·034) and 90 days (P=0·003). Infarct growth was strongly associated with poorer thrombolysis in cerebral infarction scores in target mismatch patients (P<0·001). Patients with thrombolysis in cerebral infarctionnfarction 2A reperfusion had less magnetic resonance imaging reperfusion (P=0·004) and poorer clinical outcome at 90 days (P=0·01) compared with thrombolysis in cerebral infarction 2B-3 patients. Thrombolysis in cerebral infarction reperfusion following endovascular therapy for ischemic stroke is highly correlated with magnetic resonance

    The presence of psychotic symptoms in bipolar disorder (BD) is considered a feature of higher severity of illness and, in particular, of manic episodes in bipolar I disorder (BD I). However, the possibility to apply the "with psychotic features" specifier to major depressive episodes in either bipolar II disorder (BD II) or BD I highlights the need for additional research in this area. The present study assessed the lifetime presence of psychotic symptoms and related socio-demographic and clinical features in a large sample of BD patients (N=360), with (BDPs, N=207) and without a lifetime history of psychosis (BDNPs, N=153). An overall less favorable socio-demographic profile was observed in BDPs vs BDNPs. In terms of clinical variables, BDPs vs BDNPs had: earlier age at onset (27.7±10.5 vs 30.1±12.3years; p=0.02), higher rates of BD I diagnosis (95.7% vs 45.8%; p<0.001), more elevated (manic/hypomanic/mixed) polarity of first (55.2% vs 24.4%; p<0.001) and most recent episode (69.8% vs 35.6%; p<0.001), more comorbid alcohol/substance use disorder (38.1% vs 21.9%; p=0.002), more lifetime hospitalizations (3.8±6.1 vs 2±3; p=0.002) and involuntary commitments (1±1.9 vs 0.1±0.4; p<0.001), more history of psychosocial rehabilitation (17.9% vs 5.7%; p=0.001), more current antipsychotic use (90.1% vs 70.9%; p<0.001), and lower GAF (62.3±14.2 vs 69.3±12.5; p<0.001), but shorter duration of most recent episode (34.1±45.4 vs 50.3±65.7days; p=0.04), lower rates of comorbid anxiety disorders (23.9% vs 38.2%; p=0.005), and antidepressant use (19.4% vs 56.6%; p<0.001). The present findings indicate an overall worse profile of socio-demographic and certain clinical characteristics associated with the lifetime presence of psychotic symptoms in bipolar patients.

    Background A questionnaire-based study was conducted to assess long-term patient reported outcomes (PROs) following definitive IMRT-based treatment for early stage carcinomas of the tonsillar fossa. Methods: Participants had received IMRT with or without systemic therapy for squamous carcinoma of the tonsillar fossa (T1-2 and N0-2b) with a minimum follow-up of 2 years. Patients completed a validated head and neck cancer-specific PRO instrument, the MD Anderson Symptom Inventory-Head and Neck module (MDASI-HN). Symptoms were compared between treatment groups of interest and overall symptom burden was evaluated. Results Of 139 participants analyzed, 51% had received ipsilateral neck IMRT, and 62% single modality IMRT alone (no systemic therapy). There were no differences in mean individual symptom and interference ratings for those treated with bilateral versus ipsilateral neck IMRT alone. However, 40% of those treated with bilateral versus 25% of those treated with ipsilateral neck RT alone reported moderate-to-severe levels of dry mouth (p=0.03). Fatigue, numbness/tingling, and constipation were rated more severe for those who had received systemic therapy (p<0.05 for each), but absolute differences were small. Overall, 51% had no more than mild symptom ratings across all 22 symptoms assessed. Conclusions The long-term patient reported symptom profile in this cohort of tonsil cancer survivors treated with definitive IMRT-based treatment showed a majority of patients with no more than mild symptoms, low symptom interference, and provides an opportunity for future comparison studies with other treatment approaches.

    Tumor necrosis factor α (TNF-α) inhibitors have long been used as disease-modifying agents in immune disorders. Recently, research has shown a role of chronic neuroinflammation in the pathophysiology of neurodegenerative diseases such as Alzheimer disease, and interest has been generated in the use of anti-TNF agents and TNF-modulating agents for prevention and treatment. This article extensively reviewed literature on animal studies testing these agents. The results showed a role for direct and indirect TNF-α inhibition through agents such as thalidomide, 3,6-dithiothalidomide, etanercept, infliximab, exendin-4, sodium hydrosulfide, minocycline, imipramine, and atorvastatin. Studies were performed on mice, rats, and monkeys, with induction of neurodegenerative physiology either through the use of chemical agents or through the use of transgenic animals. Most of these agents showed an improvement in cognitive function as tested with the Morris water maze, and immunohistochemical and histopathological staining studies consistently showed better outcomes with these agents. Brains of treated animals showed significant reduction in pro-inflammatory TNF-α and reduced the burden of neurofibrillary tangles, amyloid precursor protein, and β-amyloid plaques. Also, recruitment of microglial cells in the central nervous system was significantly reduced through these drugs. These studies provide a clearer mechanistic understanding of the role of TNF-α modulation in Alzheimer disease. All studies in this review explored the use of these drugs as prophylactic agents to prevent Alzheimer disease through immune modulation of the TNF inflammatory pathway, and their success highlights the need for further research of these drugs as therapeutic agents.

    Growing evidence suggests that phospholipase A2 (PLA2) plays a pivotal role in tumorigenesis in human gastrointestinal cancer. One of the well-studied isoforms of PLA2, group IIA PLA2 (PLA2G2A), appears to exert its protumorigenic or antitumorigenic effects in a tissue-specific manner. The present study was designed to determine the expression profile and prognostic value of PLA2G2A in gastric cancer in a large Chinese cohort. By using real-time polymerase chain reaction, the amount of PLA2G2A messenger RNA in 60 pairs of fresh gastric tumors and adjacent noncancerous mucosa was measured. The immunostaining of PLA2G2A in 866 gastric cancers with paired noncancerous tissues was assayed. No expression of PLA2G2A was found in normal gastric mucosa, and focal expression of PLA2G2A was noticed in intestinal metaplasia, whereas significantly increased expression of PLA2G2A was observed in the cytoplasm of gastric cancer cells. Furthermore, the extent of PLA2G2A expression was associated with tumor size (P < .001), tumor differentiation (P = .001), T class (P < .001), N class (P < .001), and TNM stage (P < .001) of gastric cancer. Multivariate analysis showed that PLA2G2A expression was an independent predictor of survival for patients with gastric cancer (P = .024). Expression of PLA2G2A seems to be protective for patients with gastric cancer (hazard ratio, 1.423; 95% confidence interval, 1.047-1.935), and it may be a target for achieving better treatment outcomes.

    Neoadjuvant chemo(radio)therapy followed by surgery is the standard of care for patients with locally advanced resectable esophageal adenocarcinoma (EAC). There is increasing evidence that drug resistance might be related to genomic heterogeneity. We investigated whether genomic tumor heterogeneity is different after cytotoxic chemotherapy and is associated with EAC patient survival. We used arrayCGH and a quantitative assessment of the whole genome DNA copy number aberration patterns (‘DNA copy number entropy’) to establish the level of genomic tumor heterogeneity in 80 EAC treated with neoadjuvant chemotherapy followed by surgery (CS group) or surgery alone (S group). The association between DNA copy number entropy, clinicopathological variables and survival was investigated. DNA copy number entropy was reduced after chemotherapy, even if there was no morphological evidence of response to therapy (p<0.001). Low DNA copy number entropy was associated with improved survival in the CS group (p=0.011) but not in the S group (p=0.396). Our results suggest that cytotoxic chemotherapy reduces DNA copy number entropy, which might be a more sensitive tumor response marker than changes in the morphological tumor phenotype. The use of DNA copy number entropy in clinical practice will require validation of our results in a prospective study. PMID:27286451

    Childhood primary angiitis of the central nervous system (cPACNS) is a rare inflammatory brain disease of unknown etiology. Of note, brain hemorrhage has been rarely reported in cPACNS patients, generally associated with a delayed clinical diagnosis, or with a diagnosis only at necropsy. We present the case of a boy with cPACNS that previously suffered an ischemic stroke. At the age of 7 years and 10 months, he presented a sudden and severe headache, vomiting and reduction in consciousness level (Glasgow coma scale 7), requiring prompt tracheal intubation. Brain computed tomography demonstrated intraparenchymal hematoma in the right parieto-occipital lobe and a small focus of bleeding in the right frontal lobe, vasogenic edema, herniation of the uncus and a 10mm deviation to the left from the midline. C-reactive protein (9.2mg/dL) and von Willebrand factor (vWF) antigen (202%) were elevated. Decompressive craniotomy was performed and methylprednisolone and cyclophosphamide were administered. One week later, the patient had left hemiparesis without other sequelae. Importantly, motor deficits have been improving progressively. Our case reinforces the inclusion of this vasculitis as a differential diagnosis in children and adolescents with CNS hemorrhage. Copyright © 2014 Elsevier Editora Ltda. All rights reserved.

    Treatment of congenital nephrotic syndrome (CNS) and steroid-resistant nephrotic syndrome (SRNS) is demanding, and renal prognosis is poor. Numerous causative gene mutations have been identified in SRNS that affect the renal podocyte. In the era of high-throughput sequencing techniques, patients with nongenetic SRNS frequently escape the scientific interest. We here present the long-term data of the German CNS/SRNS Follow-Up Study, focusing on the response to cyclosporin A (CsA) in patients with nongenetic versus genetic disease. Cross-sectional and longitudinal clinical data were collected from 231 patients with CNS/SRNS treated at eight university pediatric nephrology units with a median observation time of 113 months (interquartile range, 50-178). Genotyping was performed systematically in all patients. The overall mutation detection rate was high at 57% (97% in CNS and 41% in SRNS); 85% of all mutations were identified by the analysis of three single genes only (NPHS1, NPHS2, and WT1), accounting for 92% of all mutations in patients with CNS and 79% of all mutations in patients with SRNS. Remission of the disease in nongenetic SRNS was observed in 78% of patients after a median treatment period of 2.5 months; 82% of nongenetic patients responded within 6 months of therapy, and 98% of patients with nongenetic SRNS and CsA-induced complete remission (normalbuminemia and no proteinuria) maintained a normal renal function. Genetic SRNS, on the contrary, is associated with a high rate of ESRD in 66% of patients. Only 3% of patients with genetic SRNS experienced a complete remission and 16% of patients with genetic SRNS experienced a partial remission after CsA therapy. The efficacy of CsA is high in nonhereditary SRNS, with an excellent prognosis of renal function in the large majority of patients. CsA should be given for a minimum period of 6 months in these patients with nongenetic SRNS. In genetic SRNS, response to CsA was low and restricted to exceptional

    Limited data guide practice in evaluation and treatment of septic bursitis. We aimed to characterize clinical characteristics, microbiology, and outcomes of patients with septic bursitis stratified by bursal involvement, presence of trauma, and management type. We conducted a retrospective cohort study of adult patients admitted to a single center from 1998 to 2015 with culture-proven olecranon and patellar septic bursitis. Baseline characteristics, clinical features, microbial profiles, operative interventions, hospitalization lengths, and 60-day readmission rates were determined. Patients were stratified by bursitis site, presence or absence of trauma, and operative or non-operative management. Of 44 cases of septic bursitis, patients with olecranon and patellar bursitis were similar with respect to age, male predominance, and frequency of bursal trauma; patients managed operatively were younger (p = 0.05). Clinical features at presentation and comorbidities were similar despite bursitis site, history of trauma, or management. The most common organism isolated from bursal fluid was Staphylococcus aureus. Patients managed operatively were discharged to rehabilitation less frequently (p = 0.04). This study of septic bursitis is among the largest reported. We were unable to identify presenting clinical features that differentiated patients treated surgically from those treated conservatively. There was no clear relationship between preceding trauma or bursitis site and clinical course, management, or outcomes. Patients with bursitis treated surgically were younger. Additional study is needed to identify patients who would benefit from early surgical intervention for septic bursitis.

    This study evaluated the clinical outcome in 21 patients (22 knees) undergoing osteochondral autologous transplantation (OATS) in the knee over a 5-year period. Sixteen knees in 15 patients were available for follow-up at an average of 40 months after the procedure. The clinical outcome was analyzed using the IKDC and Knee and Osteoarthritis Outcome Score (KOOS) evaluation forms, a subjective questionnaire, and a clinical examination. At final follow-up, the average KOOS result for pain was 80.6 (range: 56-94), symptoms 53.6 (range: 25-71), function of activities of daily living 93.4 (range: 79-100), function of sports and recreational activities 65.3 (range: 20-100), and quality of life 51.0 (range: 6-88). The average IKDC score was 68.2. On our subjective questionnaire, the average preoperative grade given was 3.1 (range: 1-7) with an improvement at the most recent follow-up to a grade of 8.0 (range: 5-10) (P < .00001). Thirteen (86%) patients reported that they would have the surgery again if they had to make the decision a second time. Age did not correlate with subjective results on the IKDC evaluation (P = .7048) or score difference on our questionnaire (P = .9175). This procedure provides an option for articular resurfacing of the femoral condyles for focal areas of chondral defects with promising results regarding subjective improvement.

    The determination of appropriate duration of in-the-field cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrest (OHCA) patients is one of the biggest challenges for emergency medical service providers and clinicians. The appropriate CPR duration before termination of resuscitation remains unclear and may differ based on initial rhythm. We aimed to determine the relationship between CPR duration and post-OHCA outcomes. We analyzed the records of 17 238 OHCA patients (age ≥18 years) who achieved prehospital return of spontaneous circulation. Data were prospectively recorded in a nationwide, Japanese database between 2011 and 2012. The time from CPR initiation to prehospital return of spontaneous circulation (CPR duration) was calculated. The primary end point was 1-month survival with favorable neurological outcomes (Cerebral Performance Category [CPC] scale; CPC 1-2). The 1-month CPC 1-2 rate was 21.8% (n=3771). CPR duration was inversely associated with 1-month CPC 1-2 (adjusted unit odds ratio: 0.95, 95% CI: 0.94-0.95). Among all patients, a cumulative proportion of >99% of 1-month CPC 1-2 was achieved with a CPR duration of 35 minutes. When sorted by the initial rhythm, the CPR duration producing more than 99% of survivors with CPC 1-2 was 35 minutes for shockable rhythms and pulseless electrical activity, and 42 minutes for asystole. CPR duration was independently and inversely associated with favorable 1-month neurological outcomes. The critical prehospital CPR duration for OHCA was 35 minutes in patients with initial shockable rhythms and pulseless electrical activity, and 42 minutes in those with initial asystole. © 2016 The Authors.

    During a recent Food and Drug Administration workshop on clinical trials to evaluate new TB drugs, questions were raised regarding the use of bacteriologic endpoints such as treatment failure and relapse as measures of improvement in health status and long term outcome after treatment. FDA scientists asked how patients' clinical signs and symptoms changed during therapy, noting that while such information is usually collected during clinical trials, it is not often reported. We analyzed data from an international phase 3 TB treatment trial that included systematic assessments of symptoms. The percentage of subjects with self-reported symptoms at baseline ranged from 30% for dyspnea to 81% for cough, with 51% reporting fever. During therapy, fever, sweats, and dyspnea decreased most rapidly, with near resolution by the end of therapy. Chest pain and cough resolved more slowly; 13% of subjects reported cough at six months. Symptom resolution during treatment did not differ between those who relapsed and those who did not. Among those with microbiological relapse, symptoms returned with significant increases in the proportion with fever, cough, and chest pain. At the time of relapse, cough was the most frequent symptom, occurring in 75% of subjects who relapsed but only 12% of those who did not. Our data support the continued use of bacteriologic endpoints based on sputum culture as surrogate measures of the relief of symptoms, improvement in health status and favorable long term treatment outcome in TB drug trials.

    Recently updated phase III trials revealed the favorable effect of add-on procarbazine-lomustine-vincristine chemotherapy (CT) to radiotherapy (RT) in treating anaplastic oligodendrogliomas with 1p19q codeletion (codel). However, the underlying rationality of deferring RT and upfront CT administration for these tumors is yet to be elucidated. Here, we retrospectively analyzed the long-term outcome of our case series with oligodendroglial tumors treated with deferred RT and upfront procarbazine+nimustine+vincristine (PAV) in the introduction administration. We enrolled 36 patients with newly diagnosed oligodendroglial tumors (17, grade II and 19, grade III) treated during 1999-2012 and followed up for a median period of 69.0 months. Their clinical and genetic prognostic factors were analyzed, and progression-free survival, overall survival (OS), and deterioration-free survival (DFS) were evaluated. Regardless of the WHO grade, the 25 patients with 1p19q codel tumors never received RT initially, and of these 25, 23 received PAV treatment upfront. The 75% OS of patients with 1p19q codel tumor was 135.3 months (did not reach the median OS), indicating a favorable outcome. Multivariate analysis revealed that IDH mutation and 1p19q, not WHO grade, are independent prognostic factors; furthermore, IDH and 1p19q status stratified the cohort into 3 groups with significantly different OS. The DFS explained the prolonged survival without declining performance in patients with both grade II and III 1p19q codel tumors. Deferred RT and upfront PAV treatment for 1p19q codel oligodendrogliomas were associated with favorable outcomes without compromising performance status, regardless of WHO grade.

The 75% OS of patients with 1p19q codel tumor was 135.3 months (did not reach the median OS), indicating a favorable outcome. Multivariate analysis revealed that IDH mutation and 1p19q, not WHO grade, are independent prognostic factors; furthermore, IDH and 1p19q status stratified the cohort into 3 groups with significantly different OS. The DFS explained the prolonged survival without declining performance in patients with both grade II and III 1p19q codel tumors. Deferred RT and upfront PAV treatment for 1p19q codel oligodendrogliomas were associated with favorable outcomes without compromising performance status, regardless of WHO grade. PMID:27895504

    In 2015, the Centers for Medicare and Medicaid Services (CMS) released new summary star ratings for US hospitals based on patient experience. We aimed to test the association between CMS patient experience star ratings and clinical outcomes. We analyzed risk-adjusted data for more than 3000 US hospitals from CMS Hospital Compare using linear regression. We found that better patient experience was associated with favorable clinical outcomes. Specifically, a higher number of stars for patient experience had a statistically significant association with lower rates of many in-hospital complications. A higher patient experience star rating also had a statistically significant association with lower rates of unplanned readmissions to the hospital within 30 days. Better patient experience according to the CMS star ratings is associated with favorable clinical outcomes. These results support the inclusion of patient experience data in the framework of how hospitals are paid for services.

    Background: The Combined Quality Care Anterior Cruciate Ligament registry provides data for clinical research regarding primary anterior cruciate ligament (ACL) surgery. Purpose: To explore the data with regard to the clinical outcomes between sexes after ACL reconstruction in a Dutch population. Study Design: Cohort study; Level of evidence, 3. Methods: Data involving patients diagnosed with an ACL tear and eligible for surgery were recorded. Isokinetic muscle strength, functional muscle performance, and anterior-posterior translation of the knee joint were documented preoperatively and at 3, 6, 9, and 12 months postoperatively. Patients completed the Knee Injury and Osteoarthritis Outcome Score (KOOS), Lysholm, and Tegner rating scales during each examination using a web-based questionnaire. Results: Approximately 90% of ACL injuries occurred during sport activities. The mean (SD) age at surgery was 28 (11) years for both men and women, and the majority of patients were treated with hamstring tendon autografts (94%). Four percent received bone–patellar tendon–bone autografts, and 2% of the patients received other grafts. Preoperatively, the KOOS, Lysholm, and Tegner scores were significantly higher in males. Twelve months postoperatively, both sexes showed comparable isokinetic strength (P = .336), knee laxity (P = .680), and hop test for distance (P = .122) when comparing the injured with the uninjured side. Self-reported knee function was comparable between sexes as assessed by the KOOS (P = .202), Lysholm (P = .872), and Tegner (P = .767) questionnaires during the 12-month follow-up. Conclusion: One year after ACL surgery, all patients had improved greatly, showing only minor differences between sexes. The male group showed slightly better results when evaluating self-reported knee questionnaires. Comparable outcomes and knee function between sexes can therefore be presumed with patients who are treated with hamstring tendon autografts in a Dutch

    Juvenile idiopathic arthritis (JIA), as a chronic condition, is associated with significant disease- and treatment-related morbidity, thus impacting children's quality of life. In order to optimize JIA management, the paediatric rheumatologist has begun to regularly use measurements of disease activity developed, validated and endorsed by international paediatric rheumatology professional societies in an effort to monitor the disease course over time and assess the efficacy of therapeutic interventions in JIA patients.A literature review was performed to describe the main outcome measures currently used in JIA patients to determine disease activity status.The Juvenile Disease Activity Score (JADAS), in its different versions (classic JADAS, JADAS-CRP and cJADAS) and the validated definitions of disease activity and response to treatment represent an important tool for the assessment of clinically relevant changes in disease activity, leading more and more to a treat-to-target strategy, based on a tight and thorough control of the patient condition. Moreover, in recent years, increasing attention on the incorporation of patient-reported or parent-reported outcomes (PRCOs), when measuring the health state of patients with paediatric rheumatic diseases has emerged.We think that the care of JIA patients cannot be possible without taking into account clinical outcome measures and, in this regard, further work is required.

    Most dialysis patients are vitamin D deficient, including deficiencies in both activated vitamin D (1, 25-dihydroxyvitamin D) and the less active 25-hydroxyvitamin D. These and other abnormalities associated with chronic kidney disease (CKD), if they remain untreated, lead to secondary hyperparathyroidism and bone changes, such as osteitis fibrosa cystica. Activated vitamin D has been proven to decrease parathyroid hormone (PTH) levels in dialysis patients and is currently used for this indication. There are multiple other potential “pleotrophic” effects associated with vitamin D therapy. These include associations with lower all-cause and cardiovascular mortality, lower rates of infections and improved glycemic indexes. Meta-analyses of multiple observational studies have shown activated vitamin D therapy to be associated with improved survival. Observational data also suggest fewer infections and better glucose control. There have been no randomized clinical trials powered to evaluate mortality or other clinical outcomes. Small trials of nutritional vitamin D (ergocalciferol and cholecalciferol) showed increases in 25-hydroxyvitamin D levels without hypercalcemia or hyperphosphatemia, even when given in addition to activated vitamin D therapy. While activated vitamin D therapy is associated with improved outcomes, it also leads to higher fibroblast growth factor 23 (FGF-23) levels, which may be detrimental in dialysis patients. Further research is needed to evaluate whether activated or nutritional vitamin D therapy are beneficial in dialysis patients for outcomes other than secondary hyperparathyroidism. PMID:26424141

    Objective: To describe the baseline clinical and functional characteristics of an international cohort of 193 patients with dysferlinopathy. Methods: The Clinical Outcome Study for dysferlinopathy (COS) is an international multicenter study of this disease, evaluating patients with genetically confirmed dysferlinopathy over 3 years. We present a cross-sectional analysis of 193 patients derived from their baseline clinical and functional assessments. Results: There is a high degree of variability in disease onset, pattern of weakness, and rate of progression. No factor, such as mutation class, protein expression, or age at onset, accounted for this variability. Among patients with clinical diagnoses of Miyoshi myopathy or limb-girdle muscular dystrophy, clinical presentation and examination was not strikingly different. Respiratory impairment and cardiac dysfunction were observed in a minority of patients. A substantial delay in diagnosis was previously common but has been steadily reducing, suggesting increasing awareness of dysferlinopathies. Conclusions: These findings highlight crucial issues to be addressed for both optimizing clinical care and planning therapeutic trials in dysferlinopathy. This ongoing longitudinal study will provide an opportunity to further understand patterns and variability in disease progression and form the basis for trial design. PMID:27602406

    The past 3 decades have been characterized by an exponential growth in knowledge and advances in the clinical treatment of atrial fibrillation (AF). It is now known that AF genesis requires a vulnerable atrial substrate and that the formation and composition of this substrate may vary depending on comorbid conditions, genetics, sex, and other factors. Population-based studies have identified numerous factors that modify the atrial substrate and increase AF susceptibility. To date, genetic studies have reported 17 independent signals for AF at 14 genomic regions. Studies have established that advanced age, male sex, and European ancestry are prominent AF risk factors. Other modifiable risk factors include sedentary lifestyle, smoking, obesity, diabetes mellitus, obstructive sleep apnea, and elevated blood pressure predispose to AF, and each factor has been shown to induce structural and electric remodeling of the atria. Both heart failure and myocardial infarction increase risk of AF and vice versa creating a feed-forward loop that increases mortality. Other cardiovascular outcomes attributed to AF, including stroke and thromboembolism, are well established, and epidemiology studies have championed therapeutics that mitigate these adverse outcomes. However, the role of anticoagulation for preventing dementia attributed to AF is less established. Our review is a comprehensive examination of the epidemiological data associating unmodifiable and modifiable risk factors for AF and of the pathophysiological evidence supporting the mechanistic link between each risk factor and AF genesis. Our review also critically examines the epidemiological data on clinical outcomes attributed to AF and summarizes current evidence linking each outcome with AF. © 2017 American Heart Association, Inc.

    Recent studies have shown the efficacy of mechanical thrombectomy in acute ischemic stroke. We sought to identify prognostic parameters for clinical and radiological outcome after mechanical thrombectomy. In 34 patients (age 72 ± 13 years, 64.7% women) with acute occlusion of the distal ICA and/or M1 segment who were treated with mechanical thrombectomy, the Spearman correlation was performed to assess potential prognostic outcome parameters (age, NIHSS, ASPECT, thrombus length (TL), clot burden score (CBS), relative filling time delay (rFTD), time to recanalization (TTR) and TICI score). The modified Rankin scale (mRS) and the Alberta Stroke Program Early CT (ASPECT) score were used for clinical and radiological outcome, respectively. Receiver operating characteristic (ROC) analysis was performed to assess parameters predicting favorable clinical (ΔmRS ≤ 2) and radiological outcome (ΔASPECT ≤ 2). Variables associated with favorable clinical outcome included NIHSS, TL, TTR and TICI score (p ≤ 0.01) with NIHSS ≤ 15 (p = 0.001, area under the curve (AUC) 0.87), TL ≤ 2 cm (p = 0.017, AUC 0.75), TTR ≤ 231 min (p = 0.001 AUC 0.88) and TICI ≥ 2b (p = 0.050, AUC 0.70). Shorter TTR and higher TICI scores were associated with favorable radiological outcome (p < 0.001) with TTR ≤ 224 min (p = 0.023, AUC 0.77) and TICI ≥ 2b (p = 0.000, AUC 0.86).

    Objectives: The purpose of this study was to determine the clinical outcomes following revision anterior shoulder stabilization performed either via all-arthroscopic soft tissue repair or via Latarjet coracoid transfer. Methods: A retrospective review of prospectively collected data on 91 shoulders undergoing revision anterior shoulder stabilization was performed. All patients underwent prior soft tissue stabilization; those with prior open bone grafting procedures were excluded. For patients with 25% glenoid bone loss, Latarjet was performed (n=28). Patients were queried regarding recurrent instability (subluxation or dislocation). Clinical outcomes were evaluated using validated patient reported outcome questionnaires including the American Shoulder and Elbow Surgeons (ASES) score, Simple Shoulder Test (SST), visual analog scale (VAS) for pain, and Western Ontario Shoulder Instability Index (WOSI). Results: A total of 63 shoulders in 62 patients (46 males, 16 females) with an average age of 23.2 ± 6.9 years were included in the revision arthroscopy group. At an average follow-up of 46.9 ± 16.8 months (range, 15 to 78), the mean WOSI score was 80.1 (range, 15.0 to 100), and there were significant improvements (p<0.001) in ASES (63.7 to 85.1), SST (6.2 to 9.1), and VAS pain scores (2.89 to 0.81). Recurrent instability occurred in 12 of 63 shoulders (19%); the number of prior surgeries and baseline hyperlaxity were significant risk factors for failure (p<0.001 and p=0.04, respectively). No patients developed clinical or radiographic evidence of arthritis. A total of 28 shoulders in 28 patients (21 male, 7 female) with an average age of 27.5 years (range 14 to 45) were included in the Latarjet group. Thirteen (46%) had more than one previous stabilization attempt. ), the average WOSI score was 71.9, and there were significant improvements (p<0.001) in ASES (65.7 to 87.0), SST (7.2 to 10.3), and VAS (3.1 to 1.1). Recurrent instability occurred in 2 of 28 shoulders

    To analyze the spectrum of clinical features, management and outcome of children with documented spontaneous reduction of intussusception (SROI). Review of records of 50 children (33 boys, 17 girls; age range 11 days-15 years; mean age 4 years) with documented SROI, in whom intussusception was initially diagnosed by sonography (US) in 44, air enema in 2, and computed tomography in 4, in the 6-year period 1992-1998. Symptoms suggestive of intussusception were present in 21 (3 of whom had Henoch-Schönlein purpura and 4 had previous ileocolic intussusception reduced by air enema). Intussusception was an incidental finding in the other 29, in 28 of whom the finding was in the small bowel. Intussusception was limited to the small bowel in 43 and was ileocolic in 7. SROI was usually documented on US. Laparotomy performed in only 4 showed no evidence of intussusception or pathologic lead point. Outcome in all patients was favorable. SROI may present in symptomatic or asymptomatic children and occurs more commonly than previously reported. These intussusceptions are usually short-segment, small-bowel intussusceptions with no recognizable lead point. In asymptomatic patients, conservative observation is warranted. Intervention should be dictated by the clinical findings in symptomatic patients.

    The number of incidentally discovered adrenal lesions is increasing due to the widespread use of abdominal imaging. Although most incidentalomas are benign, larger suspicious lesions will require adrenalectomy. The aim of this study is to determine the risk of malignancy in patients undergoing surgery for adrenal incidentaloma; and to compare clinical outcomes in those with adrenocortical carcinoma (ACC) based on the mode of presentation. A retrospective study of consecutive patients who underwent adrenalectomy between 1995 and 2008 was performed. Data were retrieved from a prospectively maintained adrenal tumor database. Those with adrenal incidentaloma were selected and histopathology reviewed. All patients with ACC (presenting with symptoms or incidentally) during the same time period were identified and clinical outcomes compared. Adrenalectomy was performed in 274 patients of whom 73 (27%) were characterized pre-operatively as incidentaloma. Benign, non-functioning adrenocortical adenoma was the most common histopathological finding (46 patients, 63%). There was a trend (P = 0.08) towards increased survival amongst the seven patients with ACC presenting incidentally compared to the nine patients with symptomatic ACC. Adrenal incidentalomas have a small but important risk of malignancy. ACC presenting as incidentaloma appear to have a more favorable prognosis than symptomatic or functioning ACC. J. Surg.

We retrospectively studied all women who delivered infants between 1998 and 2007 at Massachusetts General Hospital to assess whether a previous episode of r-AKI associated with subsequent adverse maternal and fetal outcomes, including preeclampsia. AKI was defined as rise in serum creatinine concentration to 1.5-fold above baseline. We compared pregnancy outcomes in women with r-AKI without history of CKD (eGFR>90 ml/min per 1.73 m(2) before conception; n=105) with outcomes in women without kidney disease (controls; n=24,640). The r-AKI and control groups had similar prepregnancy serum creatinine measurements (0.70±0.20 versus 0.69±0.10 mg/dl; P=0.36). However, women with r-AKI had increased rates of preeclampsia compared with controls (23% versus 4%; P<0.001). Infants of women with r-AKI were born earlier than infants of controls (37.6±3.6 versus 39.2±2.2 weeks; P<0.001), with increased rates of small for gestational age births (15% versus 8%; P=0.03). After multivariate adjustment, r-AKI associated with increased risk for preeclampsia (adjusted odds ratio [aOR], 5.9; 95% confidence interval [95% CI], 3.6 to 9.7) and adverse fetal outcomes (aOR, 2.4; 95% CI, 1.6 to 3.7). When women with r-AKI and controls were matched 1:2 by age, race, body mass index, diastolic BP, parity, and diabetes status, r-AKI remained associated with preeclampsia (OR, 4.7; 95% CI, 2.1 to 10.1) and adverse fetal outcomes (OR, 2.1; 95% CI, 1.2 to 3.7). Thus, a past episode of AKI, despite return to normal renal function before pregnancy, associated with adverse outcomes in pregnancy. Copyright © 2017 by the American Society of Nephrology.

    2011-01-01

    Introduction Statins reportedly have anti-inflammatory and anti-thrombotic effects aside from cholesterol-lowering. This study aimed to evaluate the effect of pre-existing statin use on platelet activation markers and clinical outcome in acute ischemic stroke patients. Methods This prospective study evaluated 172 patients with acute ischemic stroke divided in two groups: patients with pre-existing statin (n = 43) and without pre-existing statin (66 cases with statins initiated post-stroke and 63 without statin treatment). Platelet activation markers (CD62P and CD63) were measured by flow cytometry at different time points after stroke and analyzed with clinical outcome. Results The CD62P and CD63 expressions on platelets were significantly lower in the patients with pre-existing statin use compared to the patients without pre-existing statin use on Day 1 post-stroke (p < 0.05). The CD62P expression was significantly lower in the patients with pre-existing statin use on 90 days after the acute stroke (p < 0.05). Patients with pre-existing statin use had lower incidences of early neurologic deterioration (END) than those without treatment (p < 0.05). Among several baseline clinical variables, admission NIHSS score, history of coronary artery disease, and pre-existing statin use were independent predictions of good clinical outcome at three months. Conclusions Pre-existing statin use is associated with decreased platelet activity as well as improved clinical outcome and reduced END in patients with acute ischemic stroke. PMID:21740551

    The development of computer-based image guidance has allowed stereotactic radiosurgery and radiotherapy to be freed from the constraints imposed by the stereotactic frames once required for intracranial radiosurgery. This freedom has led to the application of radiosurgery to targets outside the brain. In this paper, we briefly review the technologies, treatment parameters, and clinical outcomes of radiosurgical treatment for spinal pathology, including metastatic tumors and rare but challenging lesions such as arteriovenous malformations and benign tumors. A special emphasis is put on the newest development, fiducial-less robotic radiosurgery. Spinal radiosurgery is associated with excellent rates of tumor control and pain relief with a good dose sparing of the highly sensitive spinal cord. Further research is required to optimize treatment strategies and to assess clinical benefits and toxicity in the long term.

    Multiple sclerosis (MS) in children manifests with a relapsing-remitting MS (RRMS) disease course. Acute relapses consist of new neurologic deficits persisting greater than 24 hours, in the absence of intercurrent illness, and occur with a higher frequency early in the disease as compared to adult-onset RRMS. Most pediatric patients with MS recover well from these early relapses, and cumulative physical disability is rare in the first 10 years of disease. Brainstem attacks, poor recovery from a single attack, and a higher frequency of attacks portend a greater likelihood of future disability. Although prospective pediatric-onset MS cohorts have been established in recent years, there remains very limited prospective data detailing the longer-term clinical outcome of pediatric-onset MS into adulthood. Whether the advent of MS therapies, and the largely off-label access to such therapies in pediatric MS, has improved prognosis is unknown. MS onset during the key formative academic years, concurrent with active cognitive maturation, is an important determinant of long-term outcome, and is discussed in detail in another article in this supplement. Finally, increasing recognition of pediatric MS worldwide, recent launch of phase III trials for new agents in the pediatric MS population, and the clear imperative to more fully appreciate health-related quality of life in pediatric MS through adulthood highlight the need for standardized, validated, and robust outcome measures.

    Breast cancer carrying BRCA mutation may be highly sensitive to DNA-damaging agents. We hypothesized a better outcome for BRCA-mutated (BRCA(mut)) metastatic breast cancer (MBC) patients receiving high-dose chemotherapy and autologous hematopoietic stem cell transplantation (HDC AHSCT) versus unaffected BRCA (BRCA wild type; (BRCA(wt))) or patients without documented BRCA mutation (BRCA untested (BRCA(ut))). All female patients treated for MBC with AHSCT at Institut Paoli-Calmettes between 2003 and 2012 were included. BRCA(mut) and BRCA(wt) patients were identified from our institutional genetic database. Overall survival (OS) was the primary end point. A total of 235 patients were included. In all, 15 patients were BRCA(mut), 62 BRCA(wt) and 149 BRCA(ut). In multivariate analyses, the BRCA(mut) status was an independent prognostic factor for OS (hazard ratio (HR): 3.08, 95% confidence interval (CI): 1.10-8.64, P=0.0326) and PFS (HR: 2.52, 95% CI :1.29-4.91, P=0.0069). In this large series of MBC receiving HDC AHSCT, we report a highly favorable survival outcome in the subset of patients with documented germline BRCA mutations.

No study has yet evaluated CPR quality in ER. Retrospective analysis of CPR quality in episodes of ER. Three independent board-certified emergency physicians trained in CPR and the American Heart Association (AHA) guidelines reviewed ER episodes in two 5-year time-frames (2001-2005 and 2005-2009). Congruency with the corresponding 2000 and 2005 AHA guidelines was determined for each CPR scene. None. None. To evaluate whether CPR is in agreement with the specific algorithms of the AHA guidelines. Fisher's exact test and Mann-Whitney-U-test were used to evaluate statistical significance (P<0.05). A total of 136 on-screen cardiac arrests occurred in 174 episodes. Trauma was the leading cause of cardiac arrest (56.6%), which was witnessed in 80.1%. Return of spontaneous circulation occurred in 38.2%. Altogether, 19.1% of patients survived until ICU admission, and 5.1% were discharged alive. Only one CPR scene was in agreement with the published AHA guidelines. However, low-quality CPR and non-compliance with the guidelines resulted in favorable outcomes.

    Intraoperative adverse events are known to be associated with postoperative complications; however, little is known about whether or not blood loss during laparoscopic gastric bypass surgery affects the outcome. To see if intraoperative bleeding was associated with a less favorable outcome, and to identify patient-specific risk factors for intraoperative bleeding. Nationwide, Sweden. Patients who underwent laparoscopic gastric bypass surgery between January 8, 2007, and September 15, 2015, were included in the study. The volume of intraoperative blood loss was compared with data from follow-up at day 30 and 1 and 2 years after surgery. Patient-specific factors were analyzed as potential risk factors for intraoperative bleeding. The study included 43,157 patients. Intraoperative bleeding was associated with an increased risk for postoperative complication (100-499 mL, odds ratio [OR] 2.97, 95% confidence interval [95%CI] 2.53-3.50;>500 mL OR 3.34, 95%CI 2.05-5.44), lower weight loss (<100 mL, 82.4±24.19% excess body mass index-loss [%EBMIL]; 100-499 mL, 76.9±24.24 %EBMIL, P<.0001;>500 mL 76.9±23.89 %EBMIL, P = .063) and lower reported quality-of-life 2 years after surgery (<100 mL, Obesity-related Problem scale (OP) 21.1±24.46; 100-499 mL, OP 25.0±26.62, P = .008;>500 mL, OP 25.2±24.46, P = .272). Diabetes (OR 1.30, 95%CI 1.08-1.58), age (OR 1.02, 95%CI 1.02-1.03), and body mass index (OR 1.03, 95%CI 1.02-1.05) were patient-specific risk factors for intraoperative bleeding≥100 mL, whereas intentional preoperative weight loss was associated with a lower risk (OR .50, 95%CI .43-.57). Intraoperative bleeding was associated with less favorable outcome after laparoscopic gastric bypass surgery. Age, body mass index, and diabetes were risk factors for intraoperative bleeding, while preoperative weight reduction seems to be protective. Copyright © 2017 American Society for Bariatric Surgery.

    Purpose: Biceps tenotomy and tenodesis are effective treatment options for biceps pathology, but outcomes of revision surgery are not known. This study examines the clinical outcomes of patients who have undergone a revision biceps tenodesis. Materials and Methods: A retrospective review of all patients since 2004 (N = 21) who had undergone a revision biceps tenodesis with greater than 6-month follow-up was completed. A follow-up survey was carried out, and the visual analog scale (VAS), Single Assessment Numeric Evaluation (SANE), Simple Shoulder Test (SST), American Shoulder and Elbow Surgeons (ASES), and University of California – Los Angeles (UCLA) scores were obtained, along with SF-12 Mental (MCS-12) and Physical Component Summaries (PCS-12). Results: Indications for revision surgery were continued pain (14) and ruptured biceps (7). Complete follow-up examinations were performed in 15 of 21 patients (71.4%). Average follow-up was 33.4 ± 23.5 months. The mean postoperative scores were 1.9 out of 10, VAS; 79 out of 100, SANE; 10.2 out of 12, SST; 83 out of 100, ASES; 29 out of 35, UCLA; 44, PCS- 12; and 47.1, MCS- 12. Five patients were considered failures with a UCLA score below 27. Seventeen of twenty-one patient underwent concomitant procedures. Complete preoperative and postoperative data were collected for 14 patients. All scores demonstrated highly significant improvement from preoperative levels (P < 0.005), except for the MCS-12. There was no statistically significant difference in the outcomes of revision due to rupture and revision due to persistent pain. Conclusions: The results suggest that revision subpectoral biceps tenodesis provides significant pain relief and improvement in functional outcomes at a mean follow-up of 33.4 months. Level of Evidence: Case Series, Level 4. PMID:22787333

    Cadmium (Cd+2), a known carcinogen mimics the effects of estrogen in the uterus and mammary gland suggesting its possible involvement in the development and progression of breast cancer. This lab showed through analysis of a small set of archival human diagnostic specimens that the third isoform of the classic Cd+2 binding protein metallothionein (MT-3), is not expressed in normal breast tissue, but is expressed in some breast cancers and that expression tends to correlate with a poor disease outcome. The goals of the present study were to verify that overexpression of MT-3 in a large set of archival human diagnostic specimens tends to correlate with poor disease outcome and define the mechanism of MT-3 gene regulation in the normal breast epithelial cell. The results showed that MT-3 was expressed in approximately 90% of all breast cancers and was absent in normal breast epithelium. The lack of MT-3 staining in some cancers correlated with a favorable patient outcome. High frequency of MT-3 staining was also found for in situ breast cancer suggesting that MT-3 might be an early biomarker for breast cancer. The study also demonstrated that the MCF-10A cell line, an immortalized, non-tumorigenic model of human breast epithelial cells, displayed no basal expression of MT-3, nor was it induced by Cd+2. Treatment of the MCF-10A cells with the demethylation agent, 5-Aza-2′-deoxycytidine, or the histone deacetylase inhibitor, MS-275, restored MT-3 mRNA expression. It was also shown that the MT-3 metal regulatory elements are potentially active binders of protein factors following treatment with these inhibitors suggesting that MT-3 expression may be subject to epigenetic regulation.

    Hydroxychloroquine (HCQ) has been demonstrated to reduce the risk to develop diabetes mellitus (DM). However no previous experimental study had investigated its effect on the structure of the endocrine pancreas, islets of Langerhans (IOL), in insulin resistance (IR). In addition, the mechanism by which HCQ can prevent DM is not well understood. In this study, we hypothesized that the possible favorable outcome of HCQ may be partly achieved by its molecular effect on the endothelial stress markers as well as on the imparied balance of the adipokines that usually accompanies IR. A total of 54 rats were divided equally into; control, high fat diet (HFD) and HFD+HCQ groups (received standard chow, HFD and HFD+HCQ respectively). After 12 weeks, samples from pancreas as well as visceral adipose tissue (VAT) were histologically studied for the consequent changes. In the HFD group, there were mild degenerative changes and expansion of the IOL accompanied with a significantly increased (p<0.05) β-cell area%, mass, proliferation and neogenesis as well as a significantly decreased (p<0.05) α-cell area% compared with the other groups. On combining HCQ with HFD, reversal of these changes along with correction of the impaired adipokines levels (leptin, adiponectin, resistin, visfatin and lipocalin-2) and significant decrease (p<0.05) of the vascular endothelial stress markers (sE-selectin, sICAM and sVICAM) were manifested compared with the HFD group. Therefore, HCQ favorable effects in IR may be attributed to relieving of the endothelial stress as well as normalization of the skewed balance of adipokines.

    Introduction Chorangiomas (CAs) are the most common non-trophoblastic tumor-like-lesions of the placenta. Although the clinical significance of small CAs is unknown, the large lesions are often associated with maternal and fetal complications. The aim of our study was to assess the maternal clinical characteristics and neonatal outcome in singleton and multiple pregnancies with placental CA. Materials and Methods Among 15742 selected placentas 170 CAs were diagnosed. Pregnancy and neonatal outcomes were analyzed in singleton (n = 121) and multiple (n = 49) pregnancy groups including 121 and 100 neonates, respectively. Results The frequency of APGAR score <7 at 5 minutes (p = 0,012), abnormal pulsatility index (p = 0,034), and abnormal blood flow class (p = 0,011) were significantly higher in neonates from singleton compared to multiple pregnancies. Significantly smaller CAs in singleton pregnancies were related to small for gestational age neonates (p = 0,00040) and neonates admitted to the neonatal care unit (p = 0,028). In singleton pregnancies, significantly smaller CAs were associated to maternal preeclampsia (p = 0,039) and larger CAs to multiparity (p = 0,005) and smoking (p = 0,001) groups. The frequency of preeclampsia was high in both singleton and multiple pregnancy groups (41,32% vs 26,53%, respectively), however, the difference did not reach the level of statistical significance. Discussion A high incidence of preeclampsia in cohort of placental CA might lead to a possible recognition of CAs as potential morphologic indicator of placental hypoxia. Conclusion A more favorable pregnancy outcome in multiple gestations compared to the singleton gestations with CAs might reflect an adaptive mechanism for increased demand of oxygen and associated placental tissue hypoxia in this group.

    This study was performed to investigate the clinical outcome of childhood masturbation. For this purpose 50 children (mean age = 48.7 +/- 24.5 months, 34 girls females and 16 boys males) with masturbation symptoms were examined at first visit to the Department of Child Psychiatry and two years thereafter with psychiatric interviews. The mean masturbation frequency at the initial interview was significantly decreased after two years. It was noted that 39 children (78%) were completely recovered and 11 children (22%) continued to masturbate after two years. Children who did not recover were significantly younger, began to masturbate earlier and masturbated more frequently than others at the time of initial evaluation. It was concluded that the findings about the beneficial effect of sedative drugs in combination with parental guidance, education and means for behavior modification were promising.

    Patients with heartburn and normal upper gastrointestinal endoscopy, normal oesophageal acid exposure, no symptom-reflux association and who fail to respond to a proton-pump inhibitor are classified as having functional heartburn (FH). This study aimed (i) to characterize the symptoms and functional abnormalities of patients with FH and (ii) to describe their clinical outcome. Among all patients referred for 24 h multichannel intraluminal impedance-pH (MII-pH), patients with FH were identified. The clinical characteristics and high-resolution oesophageal pressure topography recordings of FH patients were analyzed at the time of the 24-h MII-pH test. A symptom-related and health-related quality-of-life questionnaire was then sent to FH patients to assess the long-term outcome. Forty patients fulfilled the criteria for FH, representing 8.5% of the referred population. Twenty-two months after initial testing, 66% of patients still suffered from heartburn. The rate of mixed reflux (liquid/gas) was higher in patients with persisting heartburn at the final evaluation (63 vs. 50%, P=0.04). Sixty-six per cent of patients had one or more manometric abnormalities. Acid clearance time in MII-pH was significantly higher in patients with weak peristalsis than patients with normal peristalsis (60 ± 45 vs. 31 ± 19 s, P=0.03). A high rate of mixed reflux and/or a manometric abnormality were associated with a higher risk of persistent heartburn. FH is a chronic disorder with persisting symptoms in two-thirds of patients. An increased rate of mixed reflux and/or the presence of manometric abnormalities are associated with a higher risk of persisting symptoms and may help to identify the population with unmet therapeutic needs.

    Genetic changes are infrequent in acute myeloid leukemia (AML) compared with other malignancies and often involve epigenetic regulators, suggesting that an altered epigenome may underlie AML biology and outcomes. In 96 AML cases including 65 pilot samples selected for cured/not-cured, we found higher CpG island (CGI) promoter methylation in cured patients. Expanded genome-wide digital restriction enzyme analysis of methylation data revealed a CGI methylator phenotype independent of IDH1/2 mutations we term AML-CGI methylator phenotype (CIMP) (A-CIMP(+)). A-CIMP was associated with longer overall survival (OS) in this data set (median OS, years: A-CIMP(+)=not reached, CIMP(-)=1.17; P=0.08). For validation we used 194 samples from The Cancer Genome Atlas interrogated with Illumina 450k methylation arrays where we confirmed longer OS in A-CIMP (median OS, years: A-CIMP(+)=2.34, A-CIMP(-)=1.00; P=0.01). Hypermethylation in A-CIMP(+) favored CGIs (OR: CGI/non-CGI=5.21), and while A-CIMP(+) was enriched in CEBPA (P=0.002) and WT1 mutations (P=0.02), 70% of cases lacked either mutation. Hypermethylated genes in A-CIMP(+) function in pluripotency maintenance, and a gene expression signature of A-CIMP was associated with outcomes in multiple data sets. We conclude that CIMP in AML cannot be explained solely by gene mutations (for example, IDH1/2, TET2), and that curability in A-CIMP(+) AML should be validated prospectively.Leukemia advance online publication, 31 January 2017; doi:10.1038/leu.2017.12.

    abstract Purpose: Langerhans Cell Histiocytosis (LCH) is a neoplastic disorder characterized by tissue accumulating CD1a+ histiocytes which frequently carry somatic mutations. Irrespective of mutation status, these LCH-cells display constitutively active kinases belonging to the MAPK pathway. We evaluated, in retrospect, the contribution of individual components of the MAPK-activating and chemotaxis-promoting TNF-CXCR4-CXCL12 axis to LCH manifestation and outcome. Experimental design: CXCR4, CXCL12 and TNF protein expression was immunohistochemically analyzed in 70 LCH-affected biopsies. The presence of CXCR4+CD1a+ cells in peripheral blood (PB) and/or bone marrow (BM) samples was evaluated by flowcytometry in 13 therapy-naive LCH-patients. Results: CXCL12 was detected in 68/70 (97%) biopsies. CXCR4+LCH-cells were present in 50/70 (71%) biopsies; their presence was associated with higher levels of intralesional TNF. Circulating CD1a+CXCR4+ cells were detected in 4/13 (31%) therapy-naïve LCH-patients which displayed BRAFV600E (2/4), MAP2K1 (1/4) or no (1/4) mutations in their tissues. These CD11c co-expressing CD1a+CXCR4+cells migrated to CXCL12 in chemotaxis assays. Lesional CXCR4+LCH-cells were detected in 18/20 cases who presented with LCH manifestation at multiple sites and in 5/23 (22%) patients who developed additional lesions after initially presenting with a single lesion. The CXCR4 status at onset proved to be an independent risk factor for LCH reactivation in multivariate analysis (odds ratio 10.4, p = 0.034). Conclusions: This study provides the first evidence that CXCR4 is involved in the homing and retention of LCH-cells in CXCL12-expressing tissues and qualifies CXCR4 as a candidate prognostic marker for less favorable disease outcome.

    Unlike acute lymphoblastic leukemia (ALL) in infants, MLL gene rearrangement (MLL-r) is rare in ALL children (≥1 year old). The outcome and optimal treatment options for MLL-r ALL remain controversial. Among the 1827 children enrolled in the Tokyo Children's Cancer Study Group ALL studies L95-14, L99-15, L99-1502, L04-16, and L07-1602 (1995-2009), 25 MLL-r ALL patients (1.3 %) were identified. Their median age and leukocyte count at diagnosis was 2 years old (range 1-15 years) and 27,690/μL (range 1800-1,113,000/μL), respectively. All but one patient achieved complete remission (CR) after induction therapy, and 19 underwent allogeneic hematopoietic stem cell transplantation (HSCT) in first CR according to the protocol. The 5-year event-free survival (EFS) and overall survival (OS) rate were 60.0 % [standard error (SE), 9.7 %] and 64.0 % (SE 9.6 %), respectively. Notably, 9/12 cases with MLL-AF4-positive ALL are alive in continuous CR with a 75.0 % (SE 12.5 %) EFS rate. The causes of treatment failure were as follows: one induction failure, five relapses, and five transplant-related deaths. With intensive chemotherapy and allogeneic HSCT, favorable outcome of children (≥1 year old) with MLL-AF4-positive ALL was observed. However, considering the risk of acute and late toxicities associated with HSCT, its indication should be restricted.

    Purpose/Objective(s) Optimal treatment for locally advanced rectal cancer (LARC) with distant metastasis remains elusive. We aimed to evaluate upfront systemic chemotherapy and short-course radiotherapy (RT) followed by delayed surgery for such patients, and to identify favorable prognostic factors. Materials/Methods We retrospectively reviewed 50 LARC patients (cT4 or cT3, <2 mm from the mesorectal fascia) with synchronous metastatic disease. The primary endpoint was progression-free survival (PFS). The secondary endpoints were overall survival, treatment-related toxicity, and compliance. We considered P values <0.05 significant. Results At 22 months median follow-up, the median PFS time was 16 months and the 2-year PFS rate was 34.8%. Thirty-five patients who received radical surgery for primary and metastatic tumors were designated the curable group. Six patients with clinical complete response (ypCR) of metastases who underwent radical surgery for only the primary tumor were classified as potentially curable. Nine patients who received no radical surgery (3 received palliative surgery) were deemed the palliative group. The ypCR rate among surgery patients was 13.6%. PFS rates for the curable or potentially curable groups were significantly longer than that of the palliative group (P<0.001). On multivariate analysis, solitary organ metastasis and R0 status were independent prognostic factors for PFS. Conclusions These findings demonstrated that a strong possibility that upfront chemotherapy and short-course RT with delayed surgery are an effective alternative treatment for LARC with potentially resectable distant metastasis, owing to achievement of pathologic down-staging, R0 resection, and favorable compliance and toxicity, despite the long treatment duration.

    The Anesthesia Quality Institute (AQI) was chartered in 2008 by the American Society of Anesthesiologists to develop the National Anesthesia Clinical Outcomes Registry (NACOR). In this Technical Communication, we will describe how data enter NACOR, how they are authenticated, and how they are analyzed and reported. NACOR accepts case-level administrative, clinical, and quality capture data from voluntarily participating anesthesia practices and health care facilities in the United States. All data are transmitted to the AQI in summary electronic files generated by billing, quality capture, and electronic health care record software, typically on a monthly basis. All data elements are mapped to fields in the NACOR schema in accordance with a publicly available data dictionary. Incoming data are loaded into NACOR by AQI technologists and are subject to both manual and automated review to identify systematically missing elements, miscoding, and inadvertent corruption. Data are deidentified in compliance with Health Insurance Portability and Accountability Act regulations. The database server of AQI, which houses the NACOR database, is protected by 2 firewalls within the American Society of Anesthesiologists' network infrastructure; this system has not been breached. The NACOR Participant User File, a deidentified case-level dataset of information from NACOR, is available to researchers at participating institutions. NACOR architecture and the nature of the Participant User File include both strengths and weaknesses.

    Background Hypnosis is defined as "as an interaction in which the hypnotist uses suggested scenarios ("suggestions") to encourage a person's focus of attention to shift towards inner experiences". Aim of the work The focus of this review is to summarize the findings of controlled outcome studies investigating the potential of clinical hypnosis in pediatric populations. We will examine the following themes: anesthesia, acute and chronic pain, chemotherapy-related distress, along with other specific medical issues. Results Hypnosis is an effective method to reduce pain and anxiety before, during and after the administration of anesthetics, during local dental treatments, invasive medical procedures and in burn children. Hypnosis can be successfully used to manage recurrent headaches, abdominal pain, irritable bowel syndrome and chemotherapy-related distress. Hypnosis has an important role in managing symptoms and improving the quality of life of children suffering from asthma and cystic fibrosis and in facilitating the treatment of insomnia in school-age children. Finally, hypnosis can be effectively used for the treatment of some habitual disorders such as nocturnal enuresis and dermatologic conditions, including atopic dermatitis and chronic eczema Conclusions Clinical hypnosis seems to be a useful, cheap and side-effects free tool to manage fear, pain and several kinds of stressful experiences in pediatric populations. Children who receive self-hypnosis trainings achieve significantly greater improvements in their physical health, quality of life, and self-esteem.

    Fifty-one depressed inpatients, after 1 drug-free week, were treated for 5 weeks with imipramine 4 mg/kg day. Plasma levels of imipramine (IMI) and its active metabolite desmethylimipramine (DMI) were measured weekly, 15 hours after the last drug intake. Steady state blood levels (IMI + DMI) ranged from 60 to 585 ng/ml. The mean value for plasma concentration (IMI + DMI) at day 42 was 271 ng/ml. In the same way, therapeutic effectiveness was assessed every week using the Hamilton Rating Scale for Depression (HDRS). There was a significant correlation between plasma concentration and the decrease of Hamilton scores. The IMI/DMI ratio showed a responder-nonresponder difference; 86% patients with a ratio between 0.4 and 1 were responders. Conversely, most patients with a ratio below 0.4 or above 1 were nonresponders. The ideal ratio for clinical response would be 0.68. The ratio is a subject-specific feature, able to be an early predictor of clinical outcome.

    Mucormycosis (MCM) is a life-threatening infection that carries high mortality rates despite recent advances in its diagnosis and treatment. The objective was to report 14 cases of mucormycosis infection and review the relevant literature. We retrospectively analyzed the demographic and clinical data of 14 consecutive patients that presented with MCM in a tertiary-care teaching hospital in northern Mexico. The mean age of the patients was 39.9 (range 5–65). Nine of the patients were male. Ten patients had diabetes mellitus as the underlying disease, and 6 patients had a hematological malignancy (acute leukemia). Of the diabetic patients, 3 had chronic renal failure and 4 presented with diabetic ketoacidosis. All patients had rhinocerebral involvement. In-hospital mortality was 50%. All patients received medical therapy with polyene antifungals and 11 patients underwent surgical therapy. Survivors were significantly younger and less likely to have diabetes than nonsurvivors, and had higher levels of serum albumin on admission. The clinical outcome of patients with MCM is poor. Uncontrolled diabetes and age are negative prognostic factors. PMID:25210515

    To investigate the duration of time elapsed between the onset of symptoms for necrotizing external otitis (NEO) and admission to hospital that may play a role in patient outcome. Retrospective case review. Tertiary referral center. Fourteen consecutive male patients with NEO with no improvement from the previous course of antibiotherapy and with findings of osteomyelitis on temporal bone CT, MRI, and positive detection of Tc-99m methylene diphosphonate on temporal bone, admitted as inpatients between 2008 and 2012. Medical treatment of NEO and surgical debridement. Patients were divided into 2 groups according to median time elapsed between onset of symptoms and hospitalization (<30 d or >30 d). HbA1c, fasting blood sugar, erythrocyte sedimentation rate, C-reactive protein, pain intensity, radiologic grade, improvement since diagnosis, and total time to cure were compared according to the groups. The relationships between the laboratory data were analyzed to determine the parameters associated with time to recovery. Otalgia was significantly worse in patients who were admitted to hospital greater than 30 days after symptom onset (Mann-Whitney U test, p < 0.002). Blood glucose increased related to delayed admission time (p < 0.001). CRP results were independently elevated from the admission time (p < 0.112). There was a statistically significant difference between groups according to ESR levels and recovery time (Mann-Whitney U test, p < 0.004 and p < 0.01). There was a positive correlation between HbA1c levels and recovery time in Group 1 and between ESR levels and recovery time in Group 2 (r = 0.872, p = 0.044; r = 0.630, p = 0.039). Clinical, laboratory, and outcome data worsen later than 30 days in NEO.

    To assess the impact of Crimean-Congo hemorrhagic fever (CCHF) infection during pregnancy on maternal and fetal outcomes, we present the clinical and laboratory findings and outcomes of 5 pregnant women with CCHF infection as well as fetal outcomes. We also reviewed previously reported cases with CCHF infection in pregnant women. All pregnant women with CCHF infection who had been hospitalized between August 2007 and September 2011 were included. The gestational ages at the time of CCHF infection were 8, 18, 20, 21 and 32 weeks. CCHF infection was acquired during the 1st trimester in only 1 case and resulted in spontaneous abortion. The other 4 pregnant women completely recovered, all reached a healthy full-term gestation and 4 term babies were born. All infants had normal birth weight and were found to be healthy on their first examination and follow-up. In the literature concerning CCHF infection in pregnancy, 8 published articles including case reports or case series and 1 poster presentation including 1 case could be accessed. In conclusion, there is a risk of vertical transmission of CCHF infection, and infections acquired early in gestation had a poor prognosis for the fetus.

    Appendectomy, being the most common surgical procedure performed in general surgery, is still being performed by both open and laparoscopic methods due to a lack of consensus as to which is the most appropriate method. Because further trials are necessary and few such studies have been performed in developing countries, we decided to evaluate the outcomes of the 2 procedures to share our experience with the international community. Consecutive patients with suspected acute appendicitis who underwent laparoscopic (LA) (n=48) and open (n=52) appendectomy (OA) over a period of 3 years were studied. Clinical outcomes were compared between the 2 groups in relation to operative time, analgesia used, length of hospital stay, return to work, resumption of a regular diet, and postoperative complications. Mean age of patients was 25.8 years in the laparoscopic and 25.5 years in the open group. Patient demographics were similar in both groups (P>0.05). There was significantly less need for analgesia (1.0+/-0.5 in LA and 1.5+/-0.6 doses in OA), a short hospital stay (1.4+/-0.7 in LA and 3.4+/-1.0 days in OA), early return to work (12.6+/-3.3 in LA and 19.1+/-3.1 days in OA), and less time needed to return to a regular diet (20.1+/-2.9 in LA and 22.0+/-4.7, P<0.05 in OA) in the laparoscopic appendectomy group. Operative time was significantly shorter (54.9+/-14.7 in LA and 13.6+/-12.6 minutes in OA) in the open group. Total number of complications was less in the laparoscopic group; however, there was no statistically significant difference. The laparoscopic technique is a safe and clinically beneficial operative procedure. It provides certain advantages over open appendectomy, including short hospital stay, decreased requirement of postoperative analgesia, early food tolerance, and earlier return to normal activities. Where feasible, laparoscopy should be undertaken as the initial procedure of choice for most cases of suspected appendicitis.

    Medical research continues to focus overwhelmingly on biomedical interventions, such as drugs, devices, and procedures. The dysfunctional health care cultures and systems need more attention for quality of care to improve further. The existing health services management research has not used a systematic theoretical framework to predict the effects of organizational variables on clinical outcomes. This study tests the theoretical model proposed by N. Khatri, A. Baveja, S. Boren, and A. Mammo (2006). This study surveyed employees from hospitals in Missouri. The sample consisted of 77 respondents from 16 hospitals. The control-based management approach (Management Control and Silos) was found to be positively associated with Culture of Blame and negatively with Learning From Mistakes. In contrast, the commitment-based approach (Fair Management Practices and Employee Participation) was negatively associated with Culture of Blame and positively with Learning From Mistakes, Camaraderie, and Motivation. Mediating variables of Learning From Mistakes and Camaraderie showed a significant negative relationship with Medical Errors. Learning From Mistakes, Camaraderie, and Motivation all showed a significant positive relationship with Quality of Patient Care. The mediating variables had much stronger relationships with Medical Errors and Quality of Patient Care than did the independent variables, lending support to the proposed mediation. Health care organizations can improve the quality of care and reduce medical errors significantly by enhancing learning from mistakes and boosting camaraderie and morale of their employees. They can do so by breaking down silos in their structures, implementing just and fair management practices, and involving employees in decision making.

    Peritoneal dialysis (PD) is a preferred home dialysis modality and has a number of added advantages including improved initial patient survival and cost effectiveness over haemodialysis. Despite these benefits, uptake of PD remains relatively low, especially in developed countries. Wider implementation of PD is compromised by higher technique failure from infections (e.g., PD peritonitis) and ultrafiltration failure. These are inevitable consequences of peritoneal injury, which is thought to result primarily from continuous exposure to PD fluids that are characterised by their “unphysiologic” composition. In order to overcome these barriers, a number of more biocompatible PD fluids, with neutral pH, low glucose degradation product content, and bicarbonate buffer have been manufactured over the past two decades. Several preclinical studies have demonstrated their benefit in terms of improvement in host cell defence, peritoneal membrane integrity, and cytokine profile. This paper aims to review randomised controlled trials assessing the use of biocompatible PD fluids and their effect on clinical outcomes. PMID:23251801

    The aim of this study was to review the outcomes of thyroid surgery in children operated for both benign and malignant conditions. Demography, clinical features, and surgical outcomes were noted retrospectively for operations performed during the last 23 years. Results were analyzed using Fisher exact test and Woolf (logit) method with p value < 0.05 considered as significant. In total, 61 children (43 girls and 18 boys) underwent thyroidectomy for benign (70%) and malignant (30%) conditions. Median follow-up period was 1.4 years. In the benign group, 84% children had Graves disease and 16% had other conditions. In this study, 42% children had total, 22% had near-total, 27% had subtotal, and 9% had type 2 hemithyroidectomy. In the malignant group, 50% had multiple endocrine neoplasia, 33% had papillary, 11% had follicular cancer, and 6% had B-cell lymphoma. Fifty percent children had prophylactic thyroidectomy, 44% had total thyroidectomy plus lymphadenectomy, and 6% had hemithyroidectomy. At the time of surgery, children with benign conditions were older than those with malignancy (median, 12 vs. 7.5 years). There were no incidents of postoperative bleeding or infection. Hypocalcemia was significantly more frequent in the malignant group (39 vs. 9%, p value = 0.01). The type of recurrent laryngeal nerve (RLN) injury was more serious in the benign group (one bilateral and one unilateral permanent injury) than in the malignant group (transient hoarseness in three). Overall rate of complications was higher for operations for malignancy (56 vs. 28%, p value = 0.07). In Graves disease, the subtotal thyroidectomies had a recurrence of 30% but no recurrence was seen following total or near-total thyroidectomy group (p value = 0.01). There was no recurrence in the malignant group. Children operated after 2000 were younger than those operated before 2000 (median age, 9 vs. 14 years). Malignant conditions were more common in children operated after 2000 in

    Older temporomandibular disorder patients with more general complications and health problems may have a different clinical profile and be likely to react less favorably to conservative treatment. This retrospective study compared the clinical profiles of a young (20 to 30 years) and an older (50 to 70 years) group of patients with pain and dysfunction in the temporomandibular region and to analyze treatment outcomes. Clinical profiles and treatment outcomes were studied with a standardized protocol and the Helkimo Pain and Dysfunction Index up to 1 year after initial examination. Younger and older patients with temporomandibular disorder differed only in pain intensity at initial examination, but the outcome of conservation treatment was equally successful. Conservative treatment resulted in a significant alleviation of pain and dysfunction in almost 85% of patients. Both the younger and the older patient groups benefitted from this treatment protocol and therefore can be treated in the same fashion.

    Compared with nonfunded or peer-reviewed funded projects, industry-sponsored clinical trials have traditionally been associated with more positive results. This relationship has been extensively studied in the nonsurgical literature. Although a few authors have addressed specialties, little has been reported on orthopedic clinical trials and their association with funding, study outcome, and efforts to reduce bias after randomization across journals of multiple subspecialties. For the study reported here, we selected 5 major orthopedic subspecialty journals: Journal of Bone and Joint Surgery (American Volume), Spine, Journal of Arthroplasty, Journal of Orthopaedic Trauma, and American Journal of Sports Medicine. We chose a 2-year limit for investigation (2002-2004); included all original randomized clinical trials reported in these 5 journals; and examined these trials for their study design, funding source, outcome, bias potential, and conclusion reached. Support for the 100 eligible orthopedic clinical trials was stated as coming from industry (26 trials, 26%), nonprofit sources (19 trials, 19%), and mixed sources (5 trials, 5%); no support was stated in 46 trials (46%), and support was not reported in 4 trials (4%). Of the 26 trials reporting industry support, 22 (85%) were graded as indicating an outcome favorable to the new treatment. The association between industry funding and favorable outcome was strong and significant (P<.001). In almost half of the studies reported in Journal of Bone and Joint Surgery and Spine, measures taken to reduce bias were not documented.

    2011-01-01

    Background Traumatic Brain Injury (TBI) is a major cause of death and disability. It has been postulated that brain metabolic status, intracranial pressure (ICP) and cerebral perfusion pressure (CPP) are related to patients' outcome. The aim of this study was to investigate the relationship between CPP, ICP and microdialysis parameters and clinical outcome in TBIs. Results Thirty four individuals with severe brain injury hospitalized in an intensive care unit participated in this study. Microdialysis data were collected, along with ICP and CPP values. Glasgow Outcome Scale (GOS) was used to evaluate patient outcome at 6 months after injury. Fifteen patients with a CPP greater than 75 mmHg, L/P ratio lower than 37 and Glycerol concentration lower than 72 mmol/l had an excellent outcome (GOS 4 or 5), as opposed to the remaining 19 patients. No patient with a favorable outcome had a CPP lower than 75 mmHg or Glycerol concentration and L/P ratio greater than 72 mmol/l and 37 respectively. Data regarding L/P ratio and Glycerol concentration were statistically significant at p = 0.05 when patients with favorable and unfavorable outcome were compared. In a logistic regression model adjusted for age, sex and Glasgow Coma Scale on admission, a CPP greater than 75 mmHg was marginally statistically significantly related to outcome at 6 months after injury. Conclusions Patients with favorable outcome had certain common features in terms of microdialysis parameters and CPP values. An individualized approach regarding CPP levels and cut -off points for Glycerol concentration and L/P ratio are proposed. PMID:22168902

    The primary outcome measure is the outcome that an investigator considers to be the most important among the many outcomes that are to be examined in the study. The primary outcome needs to be defined at the time the study is designed. There are 2 reasons for this: it reduces the risk of false-positive errors resulting from the statistical testing of many outcomes, and it reduces the risk of a false-negative error by providing the basis for the estimation of the sample size necessary for an adequately powered study. This article discusses the setting of the primary outcome measure, the need for it, the increased risk of false-positive and false-negative errors in secondary outcome results, how to regard articles that do not state the primary outcome, how to interpret results when secondary outcomes are statistically significant but not the primary outcome, and limitations of the concept of a primary outcome measure in clinical trial research.

    Purpose: The spinal epidural angiolipomas are rare expansive processes made of mature lipomatous and angiomatous elements. They often have a benign character. Their etiology, pathogenesis remains uncertain, and it is a cause of spinal cord compression. The magnetic resonance imaging is the most important neuroradiological examination. Histological examination is the only examination to confirm the diagnosis. Surgery is the treatment of choice. Methods: A retrospective study of all patients operated on for a spinal epidural angiolipoma at the Department of Neurosurgery at the National Institute of Neurology of Tunis between January 2000 and December 2014 (15 years) was performed. The aim of this study is to describe the clinical, radiological, histological characteristics and the treatment of this tumor. Results: A total of nine patients were operated from January 01, 2000 to November 30, 2014. The average age of our patients was 51 years with ages that ranged from 29 to 65 with a male predominance. The period between onset of symptoms and diagnosis ranged from 24 months with an average 12 months. Posterior localization of the tumor was seen in all patients. Surgical resection was performed for all cases. The postoperative course has been satisfactory, with a complete recovery of neurological functions in all patients. Conclusions: The spinal epidural angiolipomas is rare expansive process causing spinal cord compression. Treatment is exclusively surgical resection. The functional outcome of spinal epidural angiolipomas is particularly favorable with a complete neurological recovery is if the patient was quickly operated. PMID:27695535

    Adolescent acromegaly is a rare disorder and these patients present with tall stature/gigantism, tumor mass effects and menstrual irregularities. 34 consecutive (26 males) patients having onset of disease prior to 21 years of age were included in this retrospective analysis. Their clinical features and treatment outcome were studied. Mean age and lag time at presentation were 21.6 +/- 3.9 years and 5.1 +/- 3.5 years respectively. Common presenting manifestations included acral enlargement, tumor mass effects and menstrual irregularities. Mean height at presentation was 174.6 +/- 13.7 cms (range: 150-210 cm) and one third had gigantism (height > or =97th percentile, WHO growth charts). Hypertension and glucose intolerance were seen in 15% and 23.5% respectively. Mean nadir GH after glucose load was 58.2 +/- 13.7 ng/ml and IGF -1 was 534.8 +/- 132.8 ng/ml. Half of the patients had concomitant hyperprolactinemia. Almost all (97%) had macroadenoma and anterior pituitary hormone deficiencies were frequent (75%). Patients with gigantism were younger (19.6 +/- 4.9 vs. 22.6 +/- 2.9 years; p = 0.001), had higher GH values (66.68 +/- 27.22 vs. 53.98 +/- 15.99 ng/ml; p = 0.04) and hypogonadism was more common (90.9% vs. 56.5%, p = 0.03) than those with normal stature. 32 patients (94.1%) were treated primarily with surgery, 7 (21.9%) received post operative radiotherapy. Mean duration of follow up was 33.1 +/- 10.1 months. Only 30% had nadir GH values of <1 ng/ml. One third of adolescent patients had acrogigantism. These patients were younger, had higher GH levels and concurrent hypogonadism was more common. Cure could be achieved only in about one third of the patients.

    The average life expectancy is increasing worldwide, surpassing 80 years in some countries. Recently, mechanical thrombectomy (MT) using modern devices and techniques has led to improved clinical outcomes following acute ischemic stroke. However, thus far, it remains uncertain whether MT is effective in elderly patients aged over 80 years. Between July 2013 and June 2016, 207 patients with acute ischemic stroke in the anterior circulation received MT at our center. The applied MT strategies were forced arterial suction thrombectomy (FAST) and stent retriever thrombectomy. Patients were divided into those <80 years (n = 173) and those ≥80 years (n = 34). We compared clinical and angiographic parameters between groups. The median age was 67.5 in the younger group and 82 in the elderly group; 92.5% of the younger group and 70.6% of the elderly group received MT via the FAST technique. Angiographic outcomes, including procedural time, mTICI 2b-3 reperfusion (85.5% vs. 82.4%, p = 0.633), and symptomatic intracranial hemorrhage, were not different between the groups. A favorable clinical outcome rate was significantly higher in the younger group (62.4% vs. 44.1%, p = 0.047). Younger age, a low NIHSS score, and fast onset to reperfusion time were favorable prognostic factors in elderly patients. Modern MT in elderly patients with acute ischemic stroke is safe and effective compared to younger patients despite a lower favorable clinical outcome. Our findings may suggest that an appropriate MT strategy with respect to the location of the target occlusion and vascular tortuosity might be helpful to achieve fast reperfusion and improved outcomes for elderly patients.

    Cervical disc arthroplasty (CDA) is an emerging technique for the treatment of cervical degenerative disease. Multiple studies have investigated the outcomes of CDA, particularly in comparison with cervical arthrodesis techniques such as anterior cervical discectomy and fusion (ACDF). As many entities have financial interests in CDA implants, it is imperative to consider the influence of conflicts of interest on the results of studies investigating the efficacy of CDA. This study aimed to determine if there is an association between the presence of conflicts of interest among study authors and the reported outcome of studies involving CDA. This is a systematic review of clinical CDA publications until October 2016. The outcome measures are presence of conflicts of interest, level of evidence, and outcome for all included studies. PubMed and MEDLINE databases were searched for articles presenting clinical, radiographic, and cost outcomes of CDA. Data extracted from each article included title, authors, publication year, level of evidence, prosthesis type, number of operative levels, presence of conflicts of interest, and outcome. Conflicts of interest were determined by the presence of any conflicts for any author within manuscript disclosure sections or through Open Payments reporting. Outcomes of each study were graded as either favorable, unfavorable, or equivocal. The presence of conflicts of interest was tested for an association with the level of evidence and study outcome using Pearson chi-square analysis, Fisher exact test, or logistic regression for categorical variables. The authors report no conflicts of interest directly related to this work, and have not received any funds in support of this work. A total of 98 articles were included in this analysis. In total, 44.9% (44) of articles had the presence of a conflict of interest, whereas 55.1% (54) of articles did not. Conflicted studies were more likely to present level I evidence and less likely to

    To identify the anatomical and clinical parameters that predict lack of regression of superficial varicosities after ablation of the great saphenous vein. Symptomatic patients treated with endovenous ablation from August 2006 to July 2013, by a single surgeon, were included. Recorded parameters included age, sex, size, and extent of varicosities (class I-IV) (patient standing), and diameter and length (patient supine) of treated great saphenous vein. Varicose vein classification was defined as: class I ≤6 mm and localized to thigh or leg, class II ≤6 mm and present in the thigh and leg (extensive), class III >6 mm and localized to the thigh or leg, and class IV >6 mm and extensive. "Excellent" results were defined as complete resolution of varicosities, "good" results as incomplete resolution, and "poor" results as no improvement. A total of 267 patients and 302 consecutive limbs were included in the study. There were 175 females (65.5%), and the mean age was 54 years old (22-92). The CEAP classification was as follows: C2 (81.5%), C3 (6.3%), C4 (7.9%), C5 (2.0%), and C6 (2.3%). Great saphenous vein diameters was significantly larger in patients with C3-C6 (proximal 0.84 ± 0.25 versus 0.65 ± 0.21, p = < 0.0001, distal 0.58 ± 0.18 versus 0.44 ± 0.13, p < 0.0001) or class III-IV varicose veins (proximal 0.85 ± 0.25 versus 0.75 ± 0.27, p = 0.012, distal 0.62 ± 0.62 versus 0.50 ± 0.17, p < 0.0001). Class III-IV limbs had a "good/poor" result 69.8% of the time, as compared to 51.9% of the limbs class I-II varicose veins (p = 0.002). Advanced chronic venous disease (C3-C6) patients have larger diameter great saphenous veins, reflecting the progressive nature of the disease. Patients with more severe varicosities regardless of CEAP class were more likely to require a secondary procedure. The severity of the varicosities may not correlate with the degree of venous disease, but it is an indication of

    Background Traditional peripheral biofeedback has grade A evidence for effectively treating migraines. Two newer forms of neurobiofeedback, EEG biofeedback and hemoencephalography biofeedback were combined with thermal handwarming biofeedback to treat 37 migraineurs in a clinical outpatient setting. Methods 37 migraine patients underwent an average of 40 neurofeedback sessions combined with thermal biofeedback in an outpatient biofeedback clinic. All patients were on at least one type of medication for migraine; preventive, abortive or rescue. Patients kept daily headache diaries a minimum of two weeks prior to treatment and throughout treatment showing symptom frequency, severity, duration and medications used. Treatments were conducted an average of three times weekly over an average span of 6 months. Headache diaries were examined after treatment and a formal interview was conducted. After an average of 14.5 months following treatment, a formal interview was conducted in order to ascertain duration of treatment effects. Results Of the 37 migraine patients treated, 26 patients or 70% experienced at least a 50% reduction in the frequency of their headaches which was sustained on average 14.5 months after treatments were discontinued. Conclusions All combined neuro and biofeedback interventions were effective in reducing the frequency of migraines with clients using medication resulting in a more favorable outcome (70% experiencing at least a 50% reduction in headaches) than just medications alone (50% experience a 50% reduction) and that the effect size of our study involving three different types of biofeedback for migraine (1.09) was more robust than effect size of combined studies on thermal biofeedback alone for migraine (.5). These non-invasive interventions may show promise for treating treatment-refractory migraine and for preventing the progression from episodic to chronic migraine. PMID:20205867

    There are limited data on outcomes of mechanical thrombectomy for pediatric stroke using modern devices. In this study, we report two cases of pediatric acute ischemic stroke treated with mechanical thrombectomy, both with good angiographic result (TICI 3) and clinical outcome (no neurological deficits at 90 days). In addition, we conducted a literature review of all previously reported cases describing the use of modern thrombectomy devices. Including our two cases, the aggregate rate of partial or complete vessel recanalization was 100% (22/22), and the aggregate rate of favorable clinical outcome was 91% (20/22). This preliminary evidence suggests that mechanical thrombectomy with modern devices may be a safe and effective treatment option in pediatric patients with acute ischemic stroke. © The Author(s) 2016.

    This study examines the distribution of health outcomes research (HOR) studies in the clinical literature by clinical areas and journal impact factor. The authors reviewed 535 journals and divided the sample into higher and lower impact journals across four clinical area. Mann-Whitney and Kruskal-Wallis tests were used to examine differences across four categories of outcomes research articles published, specifically the incidence of articles in higher versus lower impact journals and differences across clinical areas. All high-impact journals published more safety and quality articles than process assessment, quality of life, or cost analysis studies. The number of each type of outcomes research study published was highly variable across all clinical areas. Only arthritis and outcomes research journals showed statistically significant differences between higher versus lower impact journals. Authors may benefit from considering these differences in their clinical specialty area when deciding where to submit HOR studies.

    Which imaging modality is optimal to select patients for endovascular stroke treatment remains unclear. To evaluate the effectiveness of specific magnetic resonance imaging (MRI) and clinical criteria in the selection of patients with acute ischemic stroke for thrombectomy. In this observational, single-center, prospective cohort study, we studied 72 patients with middle cerebral artery or terminal internal carotid artery occlusion using computed tomographic angiography, followed by core infarct volume determination by diffusion weighted MRI, who underwent thrombectomy after meeting institutional criteria from January 1, 2012, through December 31, 2014. In this period, 31 patients with similar ischemic strokes underwent endovascular treatment without MRI and are categorized as computed tomography only and considered in a secondary analysis. Patients were prospectively classified as likely to benefit (LTB) or uncertain to benefit (UTB) using diffusion-weighted imaging lesion volume and clinical criteria (age, National Institutes of Health Stroke Scale score, time from onset, baseline modified Rankin Scale [mRS] score, life expectancy). The 90-day mRS score, with favorable defined as a 90-day mRS score of 2 or less. Forty patients were prospectively classified as LTB and 32 as UTB. Reperfusion (71 of 103 patients) and prospective categorization as LTB (40 of 103 patients) were associated with favorable outcomes (P < .001 and P < .005, respectively). Successful reperfusion positively affected the distribution of mRS scores of the LTB cohort (P < .001). Reperfusion was achieved in 27 LTB patients (67.5%) and 24 UTB patients (75.0%) (P = .86). Favorable outcomes were obtained in 21 (52.5%) and 8 (25.0%) of LTB and UTB patients who were treated, respectively (P = .02). Favorable outcomes were observed in 20 of the 27 LTB patients (74.1%) who had successful reperfusion compared with 8 of the 24 UTB patients (33.3%) who had successful reperfusion (P

    T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive malignancy of thymocytes. Despite significant improvement in the treatment of T-ALL, approximately 20% of children and most adults succumb to resistant or relapsed disease. Transformation events occur during crucial steps of thymocyte development and have been related to the expression of certain oncogenes such as TAL2, TLX1, LYL1, LMO1, and NOTCH1. Mutations that lead to constitutive activation of NOTCH1 are most commonly found in human patients with T-ALL. Moreover, overexpression of the intracellular portion of NOTCH1 can lead to the initiation of T-ALL in mouse models. These findings suggest that NOTCH1 may promote tumorigenesis through the regulation of differentiation of leukemic cells, and, potentially, of leukemia-initiating cell identity and function. Multiple studies and clinical trials aimed at targeting NOTCH1 in T-ALL or using NOTCH1 mutations as a prognostic tool are currently underway. Recent studies unexpectedly found that activating mutations in NOTCH1 are correlated with better treatment outcome. Here we review these studies and discuss possible explanations for these findings.

    The impact of isolated v-lesions on clinical outcome in biopsies with acute cellular rejection (ACR) is unclear. Two hundred and sixty-five biopsies showing the highest ACR severity for each patient were recruited and classified into four groups: (i) acute interstitial rejection (AIR) I with minimal tubulointerstitial inflammation (TI), (ii) AIR II with intensive TI, (iii) acute vascular rejection (AVR) I with minimal TI, and (iv) AVR II with intensive TI. The complete reversal rates of AIR I and AIR II groups were marginally higher than AVR I and AVR II groups (p = 0.16). At eight yr of transplantation, the death-censored graft survival (DCGS) rate of AIR I group (93.3%) was significantly higher compared with the AVR I (72.7%) or AVR II (72.9%) group. AVR I group had a similar DCGS rate with AVR II group (72.7% vs. 74.1%), whereas AVR with v1-lesion showed significantly higher graft survival (GS) rate than those with v2-lesion (70.2% vs. 45.5%). The t-lesion of AIR and v-lesion of AVR group were associated with graft loss. The extent of TI is non-specifically associated with graft loss in biopsies with AVR; the higher grade v-lesion predicts the lower complete reversal rate and poorer long-term graft survival. © 2014 John Wiley & Sons A/S.

    Background Primary intraventricular hemorrhage (PIVH) is an uncommon type of intracerebral hemorrhage. Owing to its rarity, the clinical and radiological factors affecting outcomes in patients with PIVH have not been widely studied. Material/Methods We retrospectively reviewed 112 patients (mean age 53 years) treated for PIVH at our institution from January 2004 to December 2014. Clinical and radiological parameters were analyzed 3 months after initial presentation to identify factors associated with clinical outcomes, as assessed by the Glasgow Outcome Scale (favorable ≥4, unfavorable <4). Results Of the 99 patients who underwent angiography, causative vascular abnormalities were found in 46%, and included Moyamoya disease, arteriovenous malformation, and cerebral aneurysm. At 3 months after initial presentation, 64% and 36% of patients were in the favorable and unfavorable outcome groups, respectively. The mortality rate was 19%. However, most survivors had no or mild deficits. Age, initial Glasgow Coma Scale (GCS) score, simplified acute physiology score (SAPS II), modified Graeb score, and various radiological parameters reflecting ventricular dilatation were significantly different between the groups. Specifically, a GCS score of less than 13 (p=0.015), a SAPS II score of less than 33 (p=0.039), and a dilated fourth ventricle (p=0.043) were demonstrated to be independent predictors of an unfavorable clinical outcome. Conclusions In this study we reveal independent predictors of poor outcome in primary intraventricular hemorrhage patients, and show that nearly half of the patients in our study had predisposing vascular abnormalities. Routine angiography is recommended in the evaluation of PIVH to identify potentially treatable etiologies, which may enhance long-term prognosis. PMID:28325888

    Improved outcome of children with acute lymphoblastic leukemia (ALL) who received intensive chemotherapy was observed by the Italian Association for Pediatric Hematology Oncology (AIEOP). To verify if this improved outcome was also extended to T-cell acute lymphoblastic leukemia (T-ALL) patients after introduction of intensive chemotherapy, treatment responses of 2011 patients, including 184 with T-ALL treated over the decade 1982-1991, were analyzed. Further, the potential use of the association of presenting clinical and biologic features with treatment outcome to determine risk factors that might be useful for planning risk-directed therapeutic studies was analyzed. Of the 2011 children consecutively entered on the three sequential AIEOP trials ('82, '87, and '88), 1528 (76%) had successful immunologic studies of the bone marrow blasts. One hundred eighty-four (12%) had T-ALL. During these studies, four consecutive high-risk ALL treatment protocols (i.e., 8303, 8503, 8703, and 8803) were used. Because the treatment schedule in protocols 8503 and 8703 were almost identical, those patients were grouped together for the purpose of survival analysis. The 137 boys and 47 girls ranged in age from 16 months to 15.5 years (median, 7.8 years) at diagnosis, and 38% had a mediastinal mass. The rates of treatment response [i.e. complete remission (CR) and event free survival (EFS) rates] were compared for patients with T-ALL or B-cell progenitor ALL, overall and by individual study. Presenting features and early response to steroid monotherapy were also tested as possible prognostic factors. Overall, the CR rate was 94%, and the 7-year survival (SE) was 51.9% (4.2). T-ALL patients had a significantly worse outcome than B-lineage ALL patients [7-year EFS 40.4% (5.2) vs. 61.7% (1.7), P < 0.001]. Progressive improvement in EFS for T-ALL patients treated during 1 decade was observed, with 7-year EFS (SE) of 23.2% (8.3) for protocol 8303, 5-year EFS of 39.5% (7.1) for combined

    Abstract The clinical characteristics and surgical outcomes in a large sample of patients with intermittent exotropia (IXT) as well as an analysis of risk factors associated with surgical failures are presented in this article. Data from IXT patients who received surgical management at the Eye Hospital, in the Zhongshan Ophthalmic Center, of Sun Yat-Sen University, China from January 2009 to December 2013 were reviewed retrospectively. Included within this analysis were data from pre- and postoperative ocular motility, primary alignment, and binocular vision. A total of 1228 patients with IXT were reviewed. Males (50.4%) and females (49.6%) were nearly equally represented in this sample. Thirty-two patients (2.6%) had a family history of strabismus. The mean age at onset was 6.77 ± 6.43 years (range 7 months –48.5 years), mean duration at presentation was 7.35 ± 6.68 years (range 6 months–47 years), and mean age at surgery was 13.7 ± 8.8 years (range 3–49 years). The mean refractive error was −0.84 ± 2.69 diopter in the right eye and −0.72 ± 2.58 diopter in the left eye. Amblyopia (4.2%), oblique muscle dysfunction (7.0%), and dissociated vertical deviation (4.7%) were also present in these patients. The most common subtype of IXT was the basic type (88.1%). Orthophoria was observed in 80.5% of patients and the ratios of surgical undercorrection and overcorrection were 14.7% and 4.8%, respectively, as determined with a mean follow-up time of 7.8 ± 3.7 months. When combining ocular alignment with binocular vision as the success criteria, the success rate decreased to 35.6%. Multivariate risk factor analysis showed that only the loss of stereoacuity (P = 0.002) was associated with a poor outcome. There were no differences in the long-term results between bilateral lateral rectus recession and unilateral lateral rectus recession with medial rectus resection. Most IXT patients displayed normal vision, with few having positive

    Purpose: To report the clinical outcome and late side effect profile of proton radiotherapy in the treatment of children with parameningeal rhabdomyosarcoma (PM-RMS). Methods and Materials: Seventeen consecutive children with PM-RMS were treated with proton radiotherapy at Massachusetts General Hospital between 1996 and 2005. We reviewed the medical records of all patients and asked referring physicians to report specific side effects of interest. Results: Median patient age at diagnosis was 3.4 years (range, 0.4-17.6). Embryonal (n = 11), alveolar (n = 4), and undifferentiated (n = 2) histologies were represented. Ten patients (59%) had intracranial extension. Median prescribed dose was 50.4 cobalt gray equivalents (GyRBE) (range, 50.4-56.0 GyRBE) delivered in 1.8-2.0-GyRBE daily fractions. Median follow-up was 5.0 years for survivors. The 5-year failure-free survival estimate was 59% (95% confidence interval, 33-79%), and overall survival estimate was 64% (95% confidence interval, 37-82%). Among the 7 patients who failed, sites of first recurrence were local only (n = 2), regional only (n = 2), distant only (n = 2), and local and distant (n = 1). Late effects related to proton radiotherapy in the 10 recurrence-free patients (median follow-up, 5 years) include failure to maintain height velocity (n = 3), endocrinopathies (n = 2), mild facial hypoplasia (n = 7), failure of permanent tooth eruption (n = 3), dental caries (n = 5), and chronic nasal/sinus congestion (n = 2). Conclusions: Proton radiotherapy for patients with PM-RMS yields tumor control and survival comparable to that in historical controls with similar poor prognostic factors. Furthermore, rates of late effects from proton radiotherapy compare favorably to published reports of photon-treated cohorts.

    Few studies have examined the impact of patient weight on heart transplant (HT) outcomes. Nine outcomes were compared in 2 groups of HT recipients (N = 347) based on their mean body mass index (BMI) during the first 3 years post-HT. Group 1 consisted of 108 non-overweight patients (BMI <25; mean age 52; 29.6% females; 16.7% minorities). Group 2 consisted of 239 overweight patients (BMI ≥25; mean age 52; 15.9% females; 13.8% minorities). Outcomes were: survival, re-hospitalization, rejections, infections, cardiac allograft vasculopathy (CAV), stroke, renal dysfunction, diabetes, and lymphoma. Non-overweight patients had shorter survival, were re-hospitalized more days after the HT discharge, and had more lymphoma and severe renal dysfunction. Overweight patients had more CAV, steroid-induced diabetes, and acute rejections. Overweight HT patients had better survival, but more rejections, CAV, and diabetes. Non-overweight HT patients had worse survival, plus more re-hospitalization time, lymphoma, and renal dysfunction. Copyright © 2016 Elsevier Inc. All rights reserved.

    Comparisons of the characteristics of chronic obstructive pulmonary disease (COPD) and asthma-COPD overlap syndrome (ACOS) have been the focus of several studies since the diseases were defined by the Global Initiative for Asthma and Global Initiative for Chronic Obstructive Lung Disease guidelines. However, no consensus is available yet. In this study, we aimed to compare the characteristics of asthma-COPD overlap (ACO) and COPD. We retrospectively reviewed 1,504 patients with COPD in a Korean COPD Subtype Study cohort. The occurrence of ACO was defined as a positive response to a bronchodilator (an increase in forced expiratory volume in 1 second [FEV1] of 12% and 200 mL). Among 1,504 patients with COPD, 223 (14.8%) were diagnosed with ACO. Men (95.5%) and current smokers (32.9%) were more prevalent in the ACO group compared with the pure COPD group (90.5% and 25.3%, respectively; P=0.015 and P=0.026, respectively). Patients with ACO had a better quality of life (St. George's Respiratory Questionnaire for COPD score=31.0±18.0 [mean±standard deviation]) than those with pure COPD (35.3±19.1) (P=0.002). Although the prevalence of acute exacerbation was not different between the 2 groups, patients with severe exacerbation required hospital admission significantly more frequently in the pure COPD group than in the ACO group. Patients with ACO showed a higher likelihood of FEV1 recovery than those with pure COPD (P<0.001). We suggest that ACO is characterized by less severe symptoms, and therefore it might lead to rare severe exacerbation and the possibility of lung function recovery.

    Acute ischemic stroke (AIS) due to emergent large-vessel occlusion (ELVO) has a poor prognosis. To examine the hypothesis that a better collateral score on pretreatment CT angiography (CTA) would correlate with a smaller final infarct volume and a more favorable clinical outcome after endovascular therapy (EVT). A retrospective chart review of the University of Tennessee AIS database from February 2011 to February 2013 was conducted. All patients with CTA-proven LVO treated with EVT were included. Recanalization after EVT was defined by Thrombolysis in Cerebral Infarction (TICI) score ≥2. Favorable outcome was assessed as a modified Rankin Score ≤3. Fifty patients with ELVO were studied. The mean National Institutes of Health Stroke Scale score was 17 (2-27) and 38 of the patients (76%) received intravenous tissue plasminogen activator. The recanalization rate for EVT was 86.6%. Good clinical outcome was achieved in 32% of patients. Univariate predictors of good outcome included good collateral scores (CS) on presenting CTA (p=0.043) and successful recanalization (p=0.02). Multivariate analysis confirmed both good CS (p=0.024) and successful recanalization (p=0.009) as predictors of favorable outcome. Applying results of the multivariate analysis to our cohort we were able to determine the likelihood of good clinical outcome as well as predictors of smaller final infarct volume after successful recanalization. Good CS predict smaller infarct volumes and better clinical outcome in patients recanalized with EVT. These data support the use of this technique in selecting patients for EVT. Poor CS should be considered as an exclusion criterion for EVT as patients with poor CS have poor clinical outcomes despite recanalization. Published by the BMJ Publishing Group Limited.

    The story of the long QT syndrome involved a chance interaction that took place in 1957 when Dr. Moss was shown a unique series of ECGs with a prolonged QT interval in a young deaf boy whose recurrent syncope culminated in sudden death. Who could have predicted that this clinical experience would lead to innovative and effective new therapy for a patient with the long QT syndrome several years later and the subsequent formation of the International Long QT Registry? This Registry has stimulated interactions among and between patients and physicians and has enhanced collaborations involving clinical, genetic, and basic-science investigators. The net result has been a significant improvement in the diagnosis, treatment, and outcome of patients with the long QT syndrome and an overall advancement in the science of medicine - two of the many satisfactions that physicians can experience in the clinical practice of medicine.

    A cohort of 392 patients referred to six outpatient clinics by general practitioners during 1987 with diagnoses of rheumatoid arthritis, osteoarthritis, peripheral vascular disease, psoriasis or eczema, were studied from the time of their first attendance until up to two years later. Six consultant clinics were studied in the three specialties: rheumatology, vascular surgery and dermatology. For each specialty a clinic in both a teaching hospital and a district general hospital were included. The cohort members were predominantly middle-aged or elderly people, with a greater proportion of women, except at the vascular surgery clinic where 65% of patients were men. The 392 patients made a total of 936 visits (median two, range one-eight) during the study period; 91 patients were still attending up to two years after the first visit. Patients referred by their general practitioner for therapy were less likely to be discharged than those referred for other reasons. The principal reason for continuing attendance as perceived by patients, general practitioners and hospital doctors was the necessity for consultant supervision, although agreement was far from complete in individual cases. Junior staff tended to see a higher proportion of patients at follow-up visits than did consultants, and were found to have lower discharge rates than consultants. Analyses of data showed that at the first visit, diagnosis, disease severity and the grade of doctor seeing the patient in the clinic was significantly associated with patient discharge at the P < 0.05 level of significance. Patients considered that their visits had produced improvement in their condition in 38% of cases.(ABSTRACT TRUNCATED AT 250 WORDS)

    Background The efficacy of first-generation protease inhibitor based triple-therapy against hepatitis C virus (HCV) infection is limited in HIV/HCV-coinfected patients with advanced liver fibrosis and non-response to previous peginterferon-ribavirin. These patients have a low chance of achieving a sustained virologic response (SVR) using first generation triple-therapy, with a success rate of only 20%. We investigated the efficacy and safety of lead-in therapy with intravenous silibinin followed by triple-therapy in this difficult-to-treat patient group. Methodology Inclusion criteria were HIV/HCV coinfection with advanced liver fibrosis and documented previous treatment failure on peginterferon-ribavirin. The intervention was a lead-in therapy with intravenous silibinin 20 mg/kg/day for 14 days, followed by triple-therapy (peginterferon-ribavirin and telaprevir) for 12 weeks, and peginterferon-ribavirin alone for 36 weeks. Outcome measurements were HCV-RNA after silibinin lead-in and during triple-therapy, SVR data at week 12, and safety and tolerability of silibinin. Results We examined sixteen HIV/HCV-coinfected patients with previous peginterferon-ribavirin failure, of whom 14 had a fibrosis grade METAVIR ≥F3. All were on successful antiretroviral therapy. Median (IQR) HCV-RNA decline after silibinin therapy was 2.65 (2.1–2.8) log10 copies/mL. Fifteen of sixteen patients (94%) had undetectable HCV RNA at weeks 4 and 12, eleven patients (69%) showed end-of-treatment response (i.e., undetectable HCV-RNA at week 48), and ten patients (63%) reached SVR at week 12 (SVR 12). Six of the sixteen patients (37%) did not reach SVR 12: One patient had rapid virologic response (RVR) (i.e., undetectable HCV-RNA at week 4) but stopped treatment at week 8 due to major depression. Five patients had RVR, but experienced viral breakthroughs at week 21, 22, 25, or 32, or a relapse at week 52. The HIV RNA remained below the limit of detection in all patients during the complete

    Intradural cauda equina and conus medullaris tumors (CECMTs) are rare. Only a few large clinical series exist to date. Therefore, clinical symptoms, surgical complications, and outcomes are poorly understood. The aim of the present study was to evaluate outcome after surgery of CECMTs and to identify the factors associated with a worse clinical prognosis based on the results of a series with sufficiently high number of cases. All cases of intradural CECMTs treated surgically at the authors' department between March 2006 and May 2012 were retrospectively evaluated. Arachnoid cysts and multifocal tumors were excluded. Sixty-eight adult patients met the inclusion criteria (35 female and 33 male patients; median age 56 years). Follow-up data were available for 72% (n = 49) in a median period of 9 months. Overall, 18 tumors were located intramedullary and 50 extramedullary. The majority were nerve sheath tumors (n = 27), ependymomas (n = 17), and meningiomas (n = 9). The most common preoperative symptom was pain. The rate of new transient postoperative impairment was 18% (n = 12), and new permanent deficits were observed in only 6% (n = 4). Overall neurological improvement was achieved in 62%. The reversibility of preoperative symptoms was related to the interval between the time of symptom onset and the time of surgery and to the presence of preoperative neurological deficits. Surgery of ependymoma and carcinoma metastases was associated with a higher rate of morbidity. Intradural CECMTs present as a group of tumors with varying histological features and clinical symptoms. Symptomatic manifestation is usually unspecific, mimicking degenerative lumbar spine syndromes. Despite a significant risk of transient deterioration, early surgery is advisable because more than 94% of patients maintain at least their preoperative status and more than 60% improve during follow-up. The reversibility of preoperative symptoms is related to the duration between symptom onset and surgery

    The clinical features and outcome of small intestinal lymphoma remain unclear. We retrospectively analyzed 23 patients who had non-Hodgkin lymphoma with a small intestinal lesion. With a median follow-up of 37 months, the 5-year overall survival and failure-free survival (FFS) were 64% and 60%, respectively. In a univariate analysis, a worse performance status at the start of treatment and the occurrence of abdominal symptoms or perforation during treatment were associated with poor survival. Perforation often resulted in a dismal prognosis in patients with uncontrollable lymphoma, but not in patients with lymphoma in remission. The role of surgery in small intestinal lymphoma remains equivocal. In the current study, surgery before other therapies favorably influenced FFS, and all patients who underwent complete resection of the small intestinal lesion had extremely favorable results. Further studies are warranted to establish optimal therapeutic strategies.

  6. Estimating fetal weight for best clinical outcome

    PubMed Central

    2015-01-01

    Clinical decisions are often based on the results of third trimester sonograms, particularly with small or large babies and so accuracy of estimating fetal weight (EFW) is essential. There are numerous EFW formula available and yet in Australia no one formula has been recommended for use due to the lack of clinical evidence as to their accuracy. Objectives: 1 To assess inter/intra observer error for fetal parameter measurements with multiple observers. 2 To compare six of the most commonly used EFW formulae and analyse inter/intra formulae variations for different weight range. Method: EFW of 121 pregnancies assessed within 7 days of birth by measuring the BPD, OFD, HC, AC, FL and comparing to actual birth weight. Results: Inter‐observer error: 1.3 to 3.1%. Intra‐observer error: 1.1 to 1.9% depending on fetal parameter. Accuracy of each EFW formula changed with different weight ranges. For all formulae the highest random error occurred in the macrosomic group. The lowest random error in all weight groups was the Hadlock B formula incorporating the HC/AC/FL (7.7%). Conclusion: Considering the possible problems of head moulding this study suggests the use of: Hadlock FP et al (1982) – Formula B – incorporating HC/AC/FL. PMID:28191133

    Air embolism is a rare but potentially fatal complication of surgical procedures. Rapid recognition and intervention is critical for reducing morbidity and mortality. We retrospectively characterized our experience with air embolism during medical procedures at a tertiary medical center. Electronic medical records were searched for all cases of air embolism over a 25-year period; relevant medical and imaging records were reviewed. Sixty-seven air embolism cases were identified; the mean age was 59 years (range, 3–89 years). Ninety-four percent occurred in-hospital, of which 77.8% were during an operation/invasive procedure. Vascular access-related procedures (33%) were the most commonly associated with air embolism. Clinical signs and symptoms were related to the location the air embolus; 36 cases to the right heart/pulmonary artery, 21 to the cerebrum, and 10 were attributed to patent foramen ovale (PFO). Twenty-one percent of patients underwent hyperbaric oxygen therapy (HBOT), 7.5% aspiration of the air, and 63% had no sequelae. Mortality rate was 21%; 69% died within 48 hours. Thirteen patients had immediate cardiac arrest where mortality rate was 53.8%, compared to 13.5% (p = 0.0035) in those without. Air emboli were mainly iatrogenic, primarily associated with endovascular procedures. High clinical suspicion and early treatment are critical for survival. PMID:28106717

    Rett syndrome is a genetically based neurodevelopmental disorder. Although the clinical consequences of Rett syndrome are profound and lifelong, currently no approved drug treatments are available specifically targeted to Rett symptoms. High quality outcome measures, specific to the core symptoms of a disorder are a critical component of well-designed clinical trials for individuals with neurodevelopmental disorders. The Clinical Global Impression Scale is a measure of global clinical change with strong face validity that has been widely used as an outcome measure in clinical trials of central nervous system disorders. Despite its favorable assay sensitivity in clinical trials, as a global measure, the Clinical Global Impression Scale is not specific to the signs and symptoms of the disorder under study. Development of key anchors for the scale, specific to the disorder being assessed, holds promise for enhancing the validity and reliability of the measure for disorders such as Rett syndrome. © The Author(s) 2015.

    Levothyroxine (LT), T4, poisoning is rarely associated with a severe outcome. However, cases with significant complications have been reported. The aim of this study was to identify factors associated with symptoms of poisoning including late-onset symptoms. All enquiries to the Danish Poison Information Centre (DPIC) concerning LT poisoning between March 2007 and September 2012 were reviewed and the following parameters were recorded: age, dose, time from ingestion, multiple drug intake and symptoms. To evaluate the frequency of late-onset symptoms, a subgroup of patients without initial symptoms were contacted. A total of 181 patients were registered (112 children). Ingested LT dose ranged from 10 to 9000 mcg (median 275 mcg). A total of 29 of 181 (16%) patients were symptomatic at the time of enquiry, and there was no difference in ingested LT dose between asymptomatic and symptomatic patients, neither in children nor in adults (age 16-92 years) (p < 0.68 and p < 0.47, respectively). In total, 153 of 181 (85%) patients did not have symptoms of poisoning at the time of enquiry; however, in 9 of 21 (43%) patients, we were able to contact, late-onset symptoms existed. In none of the cases, hospital contact was needed and there were no reports of long-term sequelae. Acute LT poisoning often follows a benign course. The occurrence of symptoms appears not to be dose dependent. Late-onset symptoms seem to be common. However, all symptoms resolved spontaneously without need of medical care.

    This research aimed to provide clinicians and investigators with optimal treatment outcome criteria for accurately predicting response and remission in both research studies and clinical practice. Data from 153 adult OCD outpatients (ages 18-79) who had participated in a treatment outcome study were examined. Signal detection analysis was conducted to compare levels of Yale-Brown Obsessive Compulsive Scale (Y-BOCS) symptom percent reductions and post treatment absolute scores with Clinical Global Impression (CGI) ratings of symptom improvement and severity. Optimal cutoff criteria were based on sensitivity, specificity and efficiency and were assessed via the Quality Receiver Operating Characteristic curve. A Y-BOCS reduction of 45% was observed to be the most efficient for predicting response in research trials, whereas a reduction of 35% may be optimal for clinical use. A 55% Y-BOCS reduction was determined to be the optimal cutoff for predicting remission in both clinical and research settings. A Y-BOCS absolute raw score of 12 or less was optimal for predicting remission in a clinical setting and a raw score of 14 or below was most favorable in research trials. This research provides the first empirical contrast of optimal outcome criteria in OCD based on differing ideals of both research and practice. Copyright © 2010 Elsevier Ltd. All rights reserved.

    The selection of appropriate outcomes or domains is crucial when designing clinical trials in order to compare directly the effects of different interventions in ways that minimize bias. If the findings are to influence policy and practice then the chosen outcomes need to be relevant and important to key stakeholders including patients and the public, health care professionals and others making decisions about health care. There is a growing recognition that insufficient attention has been paid to the outcomes measured in clinical trials. These issues could be addressed through the development and use of an agreed standardized collection of outcomes, known as a core outcome set, which should be measured and reported, as a minimum, in all trials for a specific clinical area. Accumulating work in this area has identified the need for general guidance on the development of core outcome sets. Key issues to consider in the development of a core outcome set include its scope, the stakeholder groups to involve, choice of consensus method and the achievement of a consensus.

    Dermoid cysts are benign congenital orbital tumors, they are classified as choristomas. Clinical manifestations vary according to location and size. We retrospectively analyzed 43 cases of dermoid cysts surgically treated between July 1998 and March 2009. Mean patient age was 18.64 years. Among patients, 48.83% were male. Preseptal location was most common (41 cases). One of the two cases of intraorbital location required orbitotomy. We observed no complications or recurrence. Dermoid cysts are most often seen in young patients. The mean age of our patients was relatively high. The majority of dermoid cysts are periorbital in location. Superficial orbital dermoid cysts are more frequent, present earlier in life and are more easily identified than deep dermoid cysts. Imaging plays a major role in the management of deep orbital tumors. Complete surgical excision has remained the mainstay of treatment. Dermoid cysts are benign orbital tumors. Superficial dermoid cysts are the most common type. Deeper cysts require a more challenging diagnostic and therapeutic approach. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Traditional anticoagulant agents such as unfractionated heparin (UFH), low molecular weight heparins (LMWHs), fondaparinux, danaparoid and bivalirudine are used in the prevention and treatment of thromboembolic diseases. However, these agents have limitations: their constraining parenteral route of administration and the need for regular coagulation monitoring for HNF. The LMWHs, with their more predictable anticoagulant response, don't require a systematic monitoring. The usefulness of LMWHs monitoring in several clinical situations such as pregnancy, obesity and renal insufficiency is a matter of debate. Indeed, there is no agreement between French and American recommendations on this question. Others aspects are also controversial: the measure of trough anti-Xa activity during pregnancy and the optimal monitoring of LMWHs for patients with antithrombin deficiency (hepatic disease, new-borns). Different tests are available to ensure the monitoring of these drugs, we will see in this review their principle, their advantages and inconvenients. The management of heparin induced thrombocytopenia also needs parenteral anticoagulants: danaparoïd, bivalirudine or argatroban. The modalities of their monitoring are relatively unknown and are presented. Furthermore, platelet monitoring is capital. This article aims to provide guidance about laboratory testing of classic parenteral anticoagulants.

    The aim of the study was to introduce our experience of establish task-based learning outcomes for core clinical clerkships. We first define our educational goal and objectives of the clinical clerkship curriculum according to knowledge, cognitive function and skill, and attitude. We selected clinical presentations and related diseases with expert panels and allocated them to core clinical departments. We classified doctor's tasks into 6 categories: history taking, physical examination, diagnostic plan, therapeutic plan, acute and emergent management, and prevention and patient education. We described learning outcomes by task using behavioral terms. We established goals and objectives for students to achieve clinical competency on a primary care level. We selected 75 clinical presentations and described 377 learning outcomes. Our process can benefit medical schools that offer outcome-based medical education, especially for clinical clerkships. To drive effective clerkships, a supportive system including assessment and faculty development should be implemented.

    The outcome of treatment with antidepressants varies markedly across people with the same diagnosis. A clinically significant prediction of outcomes could spare the frustration of trial and error approach and improve the outcomes of major depressive disorder through individualized treatment selection. It is likely that a combination of multiple predictors is needed to achieve such prediction. We used elastic net regularized regression to optimize prediction of symptom improvement and remission during treatment with escitalopram or nortriptyline and to identify contributing predictors from a range of demographic and clinical variables in 793 adults with major depressive disorder. A combination of demographic and clinical variables, with strong contributions from symptoms of depressed mood, reduced interest, decreased activity, indecisiveness, pessimism and anxiety significantly predicted treatment outcomes, explaining 5-10% of variance in symptom improvement with escitalopram. Similar combinations of variables predicted remission with area under the curve 0.72, explaining approximately 15% of variance (pseudo R(2)) in who achieves remission, with strong contributions from body mass index, appetite, interest-activity symptom dimension and anxious-somatizing depression subtype. Escitalopram-specific outcome prediction was more accurate than generic outcome prediction, and reached effect sizes that were near or above a previously established benchmark for clinical significance. Outcome prediction on the nortriptyline arm did not significantly differ from chance. These results suggest that easily obtained demographic and clinical variables can predict therapeutic response to escitalopram with clinically meaningful accuracy, suggesting a potential for individualized prescription of this antidepressant drug.

    Healthcare information systems (HIS) play a vital role in quality of care and the organization's daily operations. Consequently, increasing numbers of clinicians have been involved in HIS implementation, particularly for clinical information systems (CIS). Implementation of these systems is a major organizational investment, and its outcomes must be assessed. The purpose of this article is to provide clinicians and frontline informaticians with a practical guide to assess these outcomes, focusing on outcome variables, assessment methods, and timing of assessment. Based on in-depth literature reviews and their empirical experiences, the authors identified 3 frequently used outcomes: user satisfaction, clinical outcomes, and financial impact. These outcomes have been assessed employing various methods, including randomized controlled trials, pre- and post-test studies, time and motion studies, surveys, and user testing. The timing for outcomes assessments varied depending on several factors, such as learning curves or patients conditions. In conclusion, outcomes assessment is essential for the success of healthcare information technology, and the CIS implementation team members must be prepared to conduct and/or facilitate these studies.

    The authors reviewed the files of all patients with chordomas who were admitted and treated at their institutions from 1975 to 2012. Patients were categorized by early local recurrence and metastasis. Aggressive clinical behavior was defined as local recurrence and metastasis within 24 months of diagnosis and adequate treatment (wide en bloc resection with microscopically negative tumor margins). According to these criteria, 13 patients (14.3%) had aggressive chordomas, including 7 men and 6 women, with mean age of 54 years (range, 37-65 years) at diagnosis and treatment. All patients had preoperative tumor biopsy, followed by resection with partial (7 patients) or total sacrectomy (6 patients). In all cases, biopsy and histologic analysis of resected tumor specimens showed conventional chordomas. Resection margins were wide (grossly negative) in 6 patients and wide contaminated in 7 patients. Mean maximum tumor diameter was 11.8 cm (range, 5-21 cm). Mean follow-up was 43 months (range, 8-131 months). Rates of local recurrence, metastasis, and death were evaluated. At the last follow-up, all patients had local recurrence at a mean of 13 months (range, 5-22 months). Histologic examination of recurrent tumors showed a dedifferentiated chordoma with a fibrosarcoma component in 2 patients and no histologic change in the remaining patients. In addition, 8 patients had metastases at a mean of 13 months (range, 4-24 months) and died of their disease. All histologic findings of metastatic lesions were similar to those of primary tumors. Early diagnosis of aggressive tumors requires close follow-up of patients with chordomas. Metastasis is common, with resultant poor survival. [Orthopedics. 2017; 40(2):e248-e254.].

    The functional outcome of patients with subarachnoid hemorrhage is difficult to predict at the individual level. The monitoring of brain energy metabolism has proven to be useful in improving the pathophysiological understanding of subarachnoid hemorrhage. Nonetheless, brain energy monitoring has not yet clearly been included in official guidelines for the management of subarachnoid hemorrhage patients, likely because previous studies compared only biological data between two groups of patients (unfavorable vs favorable outcomes) and did not determine decision thresholds that could be useful in clinical practice. Therefore, this Viewpoint discusses recent findings suggesting that monitoring biomarkers of brain energy metabolism at the level of individuals can be used to predict the outcomes of subarachnoid hemorrhage patients. Indeed, by taking into account specific neurochemical patterns obtained by local or global monitoring of brain energy metabolism, it may become possible to predict routinely, and with sufficient sensitivity and specificity, the individual outcomes of subarachnoid hemorrhage patients. Moreover, combining both local and global monitoring improves the overall performance of individual outcome prediction. Such a combined neurochemical monitoring approach may become, after prospective clinical validation, an important component in the management of subarachnoid hemorrhage patients to adapt individualized therapeutic interventions.

    CHD patients, especially those with associated hypoxaemia, usually have some level of renal function impairment, even though they are relatively young. The aim of the study was to evaluate those clinical and analytical factors that may contribute to microalbuminuria and determine the association of 24-hour proteinuria with thrombotic events and mortality. A total of 251 CHD patients were studied and demographic characteristics, blood test, and 24-hour urinalysis were analysed. Of the patients, 221 were non-hypoxaemic, and 30 were hypoxaemic (oxygen saturation of 84.3±5.9%). Of the non-hypoxaemic patients, 30 (13.6%), and of the hypoxaemic patients 9 (30%), showed proteinuria (>0.15 g/24 hours) (p=0.028). Hypoxaemic CHD patients also showed higher haematocrit (%) (50.7 (34.6; 72.1) versus 42.8 (34.6; 48.9), p<0.001), serum creatinine (mg/dl) (1.07±0.2 versus 0.96±1.9, p=0.004), microalbuminuria (mg/dl/24 hours) (1.2 (0.0; 261.5) versus 0.5 (0.0; 4.37), p<0.001), proteinuria (gr/24 hours) (1.0 (0.4; 3.1) versus 0.08 (0.04; 0.52), p=0.043), and N-terminal pro-B-type natriuretic peptide (pg/ml) (417.8 (35.7; 8534.0) versus 44.9 (0.0; 670.5), p<0.001) concentrations than non-hypoxaemic CHD patients. During a median follow-up of 26.0 (16.9; 57.7) months, five patients died - one patient had 24-hour proteinuria and four patients did not (p=0.581) - and three patients had some type of thrombosis - two patients had 24-hour proteinuria and one patient did not (p=0.014). Kaplan-Meier survival analysis showed no significant difference between CHD patients with and without 24-hour proteinuria (p=0.631). CHD patients with proteinuria have significantly more thrombosis and more hypoxaemia than those patients without proteinuria.

    Juvenile dermatomyositis is a rare childhood multisystem autoimmune disease involving primarily the skin and muscles, and it may lead to long-term disability. This study aimed to describe the clinical course of juvenile dermatomyositis and determine if any early clinical or laboratory features could predict outcome. Medical charts of patients aged ≤18 years and diagnosed with juvenile dermatomyositis (according to the criteria of Bohan and Peter) at the Pediatric Department, National Taiwan University Hospital, between 1989 and 2009 were reviewed. The endpoints for disease assessment were complete clinical response and complete clinical remission. Cox's proportional hazards model was fitted to identify important predictors of complete clinical remission. A total of 39 patients with juvenile dermatomyositis were reviewed. Two-thirds were females, and the mean age at disease onset was 81.97 ± 46.63 months. The most common initial presentations were Gottron's papule (82.1%) and muscle weakness (82.1%). After excluding one patient with an incomplete record, the remaining 31 patients who had muscle weakness were analyzed; among them, 22 (70.97%) achieved complete clinical response, but only six (19.4%) achieved complete clinical remission. Multivariate analysis showed that female sex, negative Gowers' sign at disease onset, and positive photosensitivity at disease onset were favorable factors to achieve complete clinical remission. Moreover, covariate-adjusted survival curves were drawn for making predictions of complete clinical remission. Only 13 (33.33%) patients were symptom free at the end of follow up, whereas the other 26 suffered from different kinds of complications. None of them developed malignancy, but two (5.13%) patients died during the follow-up period. Factors such as male sex and Gowers' sign were unlikely to favor the achievement of complete clinical remission in juvenile dermatomyositis. Certain complications cannot be avoided, and thus more

    Despite the favorable clinical evolution of patients with chronic myeloid leukemia (CML), resistance or intolerance to imatinib is present in approximately 35% of patients. Sokal score is a widely used risk factor, however efflux and influx transporters are provisional risk factors implicated in imatinib resistance. This study analyzed Sokal score, ABCB1, ABCG2 and OCT1 mRNA transporter expression levels as well as P-glycoprotein expression and efflux transporters activity to seek a possible correlation between these factors and the molecular response at 12 months from imatinib start as well as 8-year overall survival (OS). Low plus intermediate Sokal score correlated to optimal imatinib responses, as well as OS at 8-years, thus confirming the established role of Sokal score as a prognostic factor in CML patients. Low ABCB1 and high OCT1 mRNA levels were associated with an optimal molecular response, while the inverse levels were associated with non-responders (warning and failure) patients. Our results suggest that ABCB1 and OCT1 mRNA expressions may present biological relevance to identify responder and non-responder patients to imatinib treatment. Copyright © 2016 Elsevier Ltd.

    Missing outcome data are common in clinical trials and despite a well-designed study protocol, some of the randomized participants may leave the trial early without providing any or all of the data, or may be excluded after randomization. Premature discontinuation causes loss of information, potentially resulting in attrition bias leading to problems during interpretation of trial findings. The causes of information loss in a trial, known as mechanisms of missingness, may influence the credibility of the trial results. Analysis of trials with missing outcome data should ideally be handled with intention to treat (ITT) rather than per protocol (PP) analysis. However, true ITT analysis requires appropriate assumptions and imputation of missing data. Using a worked example from a published dental study, we highlight the key issues associated with missing outcome data in clinical trials, describe the most recognized approaches to handling missing outcome data, and explain the principles of ITT and PP analysis.

    Resective epilepsy surgery can improve seizures when the epileptogenic zone (EZ) is limited to a well-defined region. High frequency oscillations (HFO) have been recognized as having a high association with the seizure onset zone. Therefore, we retrospectively identified ictal HFOs and determined their relationship to specific intracranial features of cortical tubers in children with TSC who underwent resective surgery. We identified 14 patients with drug resistant epilepsy secondary to TSC who underwent subdural grid and strip implantation for presurgical evaluation and subsequent resection with adequate post-surgical follow-up. We aimed to determine the relationship between ictal HFOs, post-resection outcome and neuroimaging features in this population. The largest tuber was identified in all 14 patients (100%). Four patients (29%) had unusual tubers. HFOs were observed at ictal onset in all 14 patients. Seven of 10 patients with complete resection of HFOs were seizure free. The better seizure outcome (ILAE=1-3) was achieved with complete HFO resection regardless of the unique TSC structural features (p=0.0140). Our study demonstrates the presence of ripple and fast ripple range HFOs at ictal onset in children with TSC. Our study showed that complete HFO resection led to the better surgical outcome, independent of MR imaging findings.

    Importance Obesity is prevalent among hospitalized children. Knowledge of the relationship between obesity and outcomes in hospitalized children will enhance nutrition assessment and provide opportunities for interventions. Objective To systematically review the existing literature concerning the impact of obesity on clinical outcomes in hospitalized children. Evidence Acquisition PubMed, Web of Science, and EMBASE databases were searched for studies of hospitalized children aged 2 to 18 years with identified obesity and at least 1 of the following clinical outcomes: all-cause mortality, incidence of infections, and length of hospital stay. Cohort and case-control studies were included. Cross-sectional studies, studies of healthy children, and those without defined criteria for classifying weight status were excluded. The Newcastle-Ottawa Scale was used to assess study quality. Results Twenty-eight studies (26 retrospective; 24 cohort and 4 case-control) were included. Of the 21 studies that included mortality as an outcome, 10 reported a significant positive relationship between obesity and mortality. The incidence of infections was assessed in 8 of the 28 studies; 2 reported significantly more infections in obese compared with nonobese patients. Of the 11 studies that examined length of stay, 5 reported significantly longer lengths of hospital stay for obese children. Fifteen studies (53%) had a high quality score. Larger studies observed significant relationships between obesity and outcomes. Studies of critically ill, oncologic or stem cell transplant, and solid organ transplant patients showed a relationship between obesity and mortality. Conclusions and Relevance The available literature on the relationship between obesity and clinical outcomes is limited by subject heterogeneity, variations in criteria for defining obesity, and outcomes examined. Childhood obesity may be a risk factor for higher mortality in hospitalized children with critical illness

    AIM: To evaluate clinical outcomes and risk factors for endoscopic perforation during endoscopic submucosal dissection (ESD) in a prospective study. METHODS: We investigated the clinical outcomes and risk factors for the development of perforation in 98 consecutive gastric neoplasms undergoing ESD regarding. Demographic and clinical parameters including patient-, tumor-, and treatment-related factors, clinical parameters, and duration of hospital stay were analyzed for risk factors for perforation. In subgroup analysis, we also compared the clinical outcomes between perforation and “silent” free air without endoscopically visible perforation detected only by computed tomography. RESULTS: Perforation was identified in 8.2% of patients. All patients were managed conservatively by the administration of antibiotics. The mean procedure time was significantly longer in patients with endoscopic perforation than in those without. According to the receiver-operating characteristic analysis, the resulting cutoff value of the procedure time for perforation was 115 min (87.5% sensitivity, 56.7% specificity). Prolonged procedure time (≥ 115 min) was associated with an increased risk of perforation (odds ratio 9.15; 95%CI: 1.08-77.54; P = 0.04). Following ESD, body temperature and C-reactive protein level were significantly higher in patients with perforation than in those without (P = 0.02), whereas there was no difference between these patient groups on the starting day of oral intake or of hospitalization. In subgroup analysis, the post-ESD clinical course was not different between endoscopic perforation and silent free air. CONCLUSION: Only prolonged procedure time (≥ 115 min) was significantly associated with perforation. The clinical outcomes of perforation are favorable and are comparable to those of patients with or without silent free air. PMID:23772265

    Introduction: The emphasis of this research is on the Human Research Program (HRP) Exploration Medical Capability's (ExMC) "Risk of Unacceptable Health and Mission Outcomes Due to Limitations of In-Flight Medical Capabilities." Specifically, this project aims to contribute to the closure of gap ExMC 2.02: We do not know how the inclusion of a physician crew medical officer quantitatively impacts clinical outcomes during exploration missions. The experiments are specifically designed to address clinical outcome differences between physician and non-physician cohorts in both near-term and longer-term (mission impacting) outcomes. Methods: Medical simulations will systematically compare success of individual diagnostic and therapeutic procedure simulations performed by physician and non-physician crew medical officer (CMO) analogs using clearly defined short-term (individual procedure) outcome metrics. In the subsequent step of the project, the procedure simulation outcomes will be used as input to a modified version of the NASA Integrated Medical Model (IMM) to analyze the effect of the outcome (degree of success) of individual procedures (including successful, imperfectly performed, and failed procedures) on overall long-term clinical outcomes and the consequent mission impacts. The procedures to be simulated are endotracheal intubation, fundoscopic examination, kidney/urinary ultrasound, ultrasound-guided intravenous catheter insertion, and a differential diagnosis exercise. Multiple assessment techniques will be used, centered on medical procedure simulation studies occurring at 3, 6, and 12 months after initial training (as depicted in the following flow diagram of the experiment design). Discussion: Analysis of procedure outcomes in the physician and non-physician groups and their subsets (tested at different elapsed times post training) will allow the team to 1) define differences between physician and non-physician CMOs in terms of both procedure performance

    The relationship between clinical and histological parameters in collagenous colitis (CC) is poorly understood. Smoking is a risk factor for CC, whereas its impact on clinical activity and outcome is not well known. In a post hoc analysis of pooled data from two randomized controlled trials we assessed the association between demographic data (gender, age, smoking habits, family history of inflammatory bowel disease), clinical variables (duration of symptoms, mean number of stools/watery stools per day, abdominal pain, clinical remission) and histological data (thickness of the collagen band, inflammation of the lamina propria, total numbers of intraepithelial lymphocytes, degeneration). Moreover, we analysed the predictive value of baseline parameters for clinical outcome in a logistic regression model. Pooled data were available from 202 patients with active CC, of whom 36% were current smokers, 29% former smokers and 35% non-smokers. Smoking status was associated with decreased ability to achieve clinical remission (current smokers vs non-smokers: odds ratio [OR] 0.31, 95% confidence interval [CI] 0.10-0.98, p = 0.045; former smokers vs non-smokers: OR 0.19, 95% CI 0.05-0.73, p = 0.016). Current smokers had an increased mean number of watery stools at baseline compared with non-smokers (p = 0.051) and increased mean number of watery stools per se was associated with decreased likelihood of obtaining clinical remission (OR 0.63, 95% CI 0.47-0.86, p = 0.003). Patient characteristics and histology at baseline had no association with clinical parameters and no predictive value for clinical outcome. Smoking worsens clinical symptoms in CC and is associated with an increased number of watery stools and decreased likelihood of achieving clinical remission. There is no significant association between histology and clinical data. Copyright © 2015 European Crohn’s and Colitis Organisation (ECCO). Published by Oxford University Press. All rights reserved.

    Decision making in evidence-based medicine is based on general data on therapy outcomes as well as the effectiveness and safety in specific patient populations. Typically, findings concerning therapy outcomes from different studies are aggregated for a final conclusion. In this context a comparison of results is hampered by studies in which therapy outcomes are heterogeneously measured. Such methodological challenges exist for almost all areas of medical treatment, as well as for multimodal pain therapy (MMPT). Through establishing core outcome sets (COS) the required standardization of measurement of therapy outcomes in clinical research can be achieved. A COS is an evidence-based and consented minimum set consisting of outcome domains (i.e. partial aspects of the medical condition to be investigated, which have to be measured in order to give the best possible demonstration of therapy outcome of an intervention) accomplished by valid, reliable and sensitive measurement instruments which should be applied in each clinical trial. No such COS has so far been found for MMPT. The aim of this article is to give an overview about currently recommended methodological approaches to develop a COS accompanied by a brief introduction about existing COS initiatives focusing on chronic pain. The existing COS recommendations are discussed and conclusions are drawn on whether existing recommendations could also be applied for MMPT. Finally, the impact of healthcare research in Germany on a standardized assessment of therapy outcome in MMPT is outlined.

    Due to the heterogeneous nature of the disease, it is a challenge to capture disease activity of multiple sclerosis (MS) in a reliable and valid way. Therefore, it can be difficult to assess the true efficacy of interventions in clinical trials. In phase III trials in MS, the traditionally used primary clinical outcome measures are the Expanded Disability Status Scale and the relapse rate. Secondary outcome measures in these trials are the number or volume of T2 hyperintense lesions and gadolinium-enhancing T1 lesions on magnetic resonance imaging (MRI) of the brain. These secondary outcome measures are often primary outcome measures in phase II trials in MS. Despite several limitations, the traditional clinical measures are still the mainstay for assessing treatment efficacy. Newer and potentially valuable outcome measures increasingly used or explored in MS trials are, clinically, the MS Functional Composite and patient-reported outcome measures, and on MRI, brain atrophy and the formation of persisting black holes. Several limitations of these measures have been addressed and further improvements will probably be proposed. Major improvements are the coverage of additional functional domains such as cognitive functioning and assessment of the ability to carry out activities of daily living. The development of multidimensional measures is promising because these measures have the potential to cover the full extent of MS activity and progression. In this review, we provide an overview of the historical background and recent developments of outcome measures in MS trials. We discuss the advantages and limitations of various measures, including newer assessments such as optical coherence tomography, biomarkers in body fluids and the concept of 'no evidence of disease activity'.

    Cutaneous melanoma (CM) is the most lethal form of skin cancer. Despite the constant increase in melanoma incidence, which is in part due to incremental advances in early diagnostic modalities, mortality rates have not improved over the last decade and for advanced stages remain steadily high. While conventional prognostic biomarkers currently in use find significant utility for predicting overall general survival probabilities, they are not sensitive enough for a more personalized clinical assessment on an individual level. In recent years, the advent of genomic technologies has brought the promise of identification of germline DNA alterations that may associate with CM outcomes and hence represent novel biomarkers for clinical utilization. This review attempts to summarize the current state of knowledge of germline genetic factors studied for their impact on melanoma clinical outcomes. We also discuss ongoing problems and hurdles in validating such surrogates, and we also project future directions in discovery of more powerful germline genetic factors with clinical utility in melanoma prognostication.

    The optimal extent of lymph node dissection (LND) is currently not established, and the debate regarding the association between the number of dissected nodes and the outcomes of bladder cancer treated by radical cystectomy (RC) is still ongoing. Therefore, the present meta-analysis was performed to clarify this potential relationship. Eligible studies were retrieved via an electronic search for studies published up to April 2016, and by manual review of the references. A total of 25 cohort studies involving 41,400 bladder cancer patients who underwent RC were included. The summary relative risk estimates (SRRE) based on the highest compared with the lowest categories of LND were estimated by variance-based meta-analysis. Heterogeneity among the study results was explored through stratified analyses. Overall, bladder cancer patients with the highest category of LND had 28%, 34% and 36% reduced risks, corresponding to overall survival (SRRE = 0.72; 95% CI, 0.64–0.80), cancer-specific survival (SRRE = 0.66; 95% CI, 0.54–0.80) and recurrence-free survival (SRRE = 0.64; 95% CI, 0.50–0.82), respectively, compared with patients with the lowest category of LND. In summary, the patients with a greater number of dissected lymph nodes had statistically significant survival advantages in terms of the outcomes of bladder cancer following RC. The number of dissected lymph nodes could be an independent prognostic factor for bladder cancer. These findings need to be validated in prospective and larger epidemiological studies with a longer follow-up period. PMID:27542252

    The pathogenesis of systemic sclerosis (SSc) is complex and largely unclear. The clinical heterogeneity of the disease and its progression over a number of years makes the choice of endpoints in the design of clinical trials difficult. The overwhelming need in this disease is to diagnose it early and identify those patients who will benefit most from early, aggressive treatment that potentially can alter the clinical disease course. To achieve this, innumerable challenges must be overcome. This article reviews data from recent clinical trials and the lessons derived from retrospective observational studies, databases, and patient registries. Taken together, these observations will help to improve our understanding of the diverse clinical course of SSc and permit refinement of existing outcome measures for the design of future clinical trials, in which the likelihood of observing a positive treatment effect with the drugs at our disposal will be maximized.

    Background and Purpose This study aimed to estimate the changes in gray matter volume (GMV) and their hemispheric difference in patients with mesial temporal lobe epilepsy (MTLE) using a voxel-based morphometry (VBM) methodology, and to determine whether GMV changes are correlated with clinical features. Methods VBM analysis of brain MRI using statistical parametric mapping 8 (SPM8) was performed for 30 left MTLE (LMTLE) and 30 right MTLE (RMTLE) patients and 30 age- and sex-matched healthy controls. We also analyzed the correlations between GMV changes and clinical features of MTLE patients. Results In SPM8-based analyses, MTLE patients showed significant GMV reductions in the hippocampus ipsilateral to the epileptic focus, bilateral thalamus, and contralateral putamen in LMTLE patients. The GMV reductions were more extensive in the ipsilateral hippocampus, thalamus, caudate, putamen, uncus, insula, inferior temporal gyrus, middle occipital gyrus, cerebellum, and paracentral lobule in RMTLE patients. These patients also exhibited notable reductions of GMV in the contralateral hippocampus, thalamus, caudate, putamen, and inferior frontal gyrus. We observed that GMV reduction was positively correlated with several clinical features (epilepsy duration and seizure frequency in RMTLE, and history of febrile seizure in LMTLE) and negatively correlated with seizure onset age in both the RMTLE and LMTLE groups. Conclusions Our study revealed GMV decreases in the hippocampus and extrahippocampal regions. Furthermore, the GMV reduction was more extensive in the RMTLE group than in the LMTLE group, since it included the contralateral hemisphere in the former. This difference in the GMV reduction patterns between LMTLE and RMTLE may be related to a longer epilepsy duration and higher seizure frequency in the latter. PMID:27449913

    Efforts are underway for early-phase trials of candidate therapies for cerebral amyloid angiopathy (CAA), an untreatable cause of hemorrhagic stroke and vascular cognitive impairment. A major barrier to these trials is the lack of consensus on measuring treatment effectiveness. We review a range of potential outcome markers for CAA against the ideal criteria of being clinically meaningful, closely reflective of biological progression, efficient for smaller/shorter trials, reliably measurable, and cost effective. In practice, outcomes tend either to have high clinical salience but relatively low statistical efficiency and thus more applicability for later phase studies, or greater statistical efficiency but more limited clinical meaning. The most statistically efficient outcomes are those that are potentially reversible with treatment, though their clinical significance remains unproven. Many of the candidate outcomes for CAA trials are likely to be applicable to other small vessel brain diseases as well. Considerations emerging from this review outline a path towards rapid and efficient testing of emerging candidate therapies for CAA and other small vessel diseases. PMID:24581702

    Anemia management clinics have demonstrated favorable impacts on clinical and economic outcomes and patient satisfaction. Clinical pharmacists are uniquely qualified to manage complex drug therapies requiring intensive monitoring. The complexity, risks associated with inappropriate treatment, and high cost of erythropoietin-stimulating agents (ESAs) make patients on these medications excellent candidates for clinical pharmacist-based management. Integrating ESA management into a clinical pharmacist-managed service has the potential to improve anemia management not only by improving patient outcomes and patient safety, but also by decreasing medication costs. To (a) assess adherence to monitoring guidelines, efficacy, and safety outcomes and (b) quantify medication utilization expenditures among patients using ESA therapy managed by a clinical pharmacy service compared with usual care. This is a retrospective longitudinal cohort study of patients with anemia caused by chronic kidney disease who were on ESA treatment for at least 6 months between January 2008 and December 2010. Adherence to monitoring guidelines, efficacy, safety, and drug utilization outcomes were compared between the 2 groups. A total of 101 patients were included in the study. Of that number, 31 were managed by the pharmacist-managed anemia service, and 70 were in the usual care group. The pharmacist-managed patients had improved adherence to guidelines for hemoglobin monitoring (32.3% vs. 14.3%, P = 0.049) and iron monitoring (61.3% vs. 30.0%, P = 0.005) compared with similar patients receiving usual care. Time to achievement of hemoglobin target was 28 days in the pharmacist-managed group compared with 41 days in the usual care group (P = 0.135), while the proportion of patients achieving target hemoglobin was 96.8% compared with 95.7%, respectively (P = 0.654). Patients in the pharmacist-managed group used less epoetin alfa during the 6-month period, leading to an annualized

    Objective The objective of this paper is to assess the reliability and validity of the Spanish translation of the Clinical Outcomes in Routine Evaluation – Outcome Measure, a 34-item self-report questionnaire that measures the client’s status in the domains of Subjective well-being, Problems/Symptoms, Life functioning, and Risk. Method Six hundred and forty-four adult participants were included in two samples: the clinical sample (n=192) from different mental health and primary care centers; and the nonclinical sample (n=452), which included a student and a community sample. Results The questionnaire showed good acceptability and internal consistency, appropriate test–retest reliability, and acceptable convergent validity. Strong differentiation between clinical and nonclinical samples was found. As expected, the Risk domain had different characteristics than other domains, but all findings were comparable with the UK referential data. Cutoff scores were calculated for clinical significant change assessment. Conclusion The Spanish version of the Clinical Outcomes in Routine Evaluation – Outcome Measure showed acceptable psychometric properties, providing support for using the questionnaire for monitoring the progress of Spanish-speaking psychotherapy clients.

    Paired-like homeodomain transcription factor 1 (PITX1) has been implicated as a tumor suppressor in various cancers. However, the biological and clinical significance of PITX1 in osteosarcoma has not been fully elucidated. Here, we studied the expression and clinical significance of PITX1 in 6 normal lower limb bone tissue specimens and 35 osteosarcoma tissue samples by immunohistochemistry. PITX1 was expressed in all normal tissues (6/6, 100 %) and in 85.7 % (30/35) of tumor tissues (P > 0.05). In addition, all normal tissue specimens showed high PITX1 expression (6/6, 100 %) while only 23.3 % (7/30) osteosarcoma tissue specimens had high PITX1 expression (P < 0.05). Patients with median overall survival (OS) >12 months had significantly higher PITX1 levels compared with those whose median OS was less than or equal to 12 months (P < 0.05 or 0.001). Furthermore, patients with lung metastasis had significantly lower PITX1 levels than patients without lung metastasis. In conclusion, PITX1 expression is downregulated in osteosarcoma and correlates with patient survival and lung metastasis.

    Background: Febrile neutropenia (FN) is common in cancer patients particularly hematologic malignancies due to intensive cytotoxic chemotherapy. It is an important cause of morbidity, mortality and treatment delays. The risk is greater in patients with ANC < 500/ mm3 and increases dramatically in those with ANC < 100/ mm3 and duration of neutropenia more than 1 week. Aims and Objectives: The purpose of this study was to evaluate the incidence, demographic characteristics, clinical profile, mortality, outcome and factors affecting the outcome in patients with febrile neutropenia (FN) admitted at our Center between January 2011 and November 2012. Materials and Methods: All cases of FN admitted in our Institute between January 2011 and November 2012 were analyzed. Data was analyzed using IBM statistic SPSS version 19. Results: A total of 333 episodes of FN were reviewed. Hematologic malignancies accounted for 299 (89.7%) episodes and 88% of all the episodes had grade 4 neutropenia. There was a significant association noted between high serum bilirubin, creatinine and outcome. Isolation of an organism from blood culture, positive findings on chest X-ray and fungal infection was associated with higher mortality. Association between transfusion requirements and outcome was analyzed and it was observed that patients who had multiple component transfusions vs single component ones were at a significantly higher risk of death. There were only 7 deaths noted among the patient population. Conclusion: Leukemias are the leading cause of FN at our Institute. Higher bilirubin, creatinine, chest imaging favoring pneumonia, positive isolates and multiple transfusions had significant association with mortality. Large scale prospective studies are needed to determine the association of preemptive therapy with higher mortality. The outcome of high risk FN in this study is favorable. PMID:28413792

    Neuroblastoma grows within an intricate network of different cell types including epithelial, stromal and immune cells. The presence of tumor-infiltrating T cells is considered an important prognostic indicator in many cancers, but the role of these cells in neuroblastoma remains to be elucidated. Herein, we examined the relationship between the type, density and organization of infiltrating T cells and clinical outcome within a large collection of neuroblastoma samples by quantitative analysis of immunohistochemical staining. We found that infiltrating T cells have a prognostic value greater than, and independent of, the criteria currently used to stage neuroblastoma. A variable in situ structural organization and different concurrent infiltration of T-cell subsets were detected in tumors with various outcomes. Low-risk neuroblastomas were characterized by a higher number of proliferating T cells and a more structured T-cell organization, which was gradually lost in tumors with poor prognosis. We defined an immunoscore based on the presence of CD3+, CD4+ and CD8+ infiltrating T cells that associates with favorable clinical outcome in MYCN-amplified tumors, improving patient survival when combined with the v-myc avian myelocytomatosis viral oncogene neuroblastoma derived homolog (MYCN) status. These findings support the hypothesis that infiltrating T cells influence the behavior of neuroblastoma and might be of clinical importance for the treatment of patients. PMID:26405592

    Objective Patient and device selection are important for the success of carotid artery stenting (CAS). We hypothesize that distal protection filter (DPF) design characteristics that minimize blood flow resistance and maximize capture efficiency are associated with the absence of transient ischemic attack (TIA), stroke and neurologic-related death after 30 days. Methods Records from 208 patients were reviewed retrospectively. Filter design characteristics were quantified previously in our laboratory. The association between risk factors and design characteristics with 30-day outcome was quantified using univariate analysis. Results The 30-day all-cause stroke and death rate was 8.7% (asymptomatic: 7.7%, symptomatic: 10.6%). Five DPFs were used in the study: Accunet (41.3%), Angioguard (33.2%), FilterWire (24%), Emboshield (1%), and Spider (0.5%). Diabetes (P = .04) and prior carotid endarterectomy (CEA, P = .03) were associated with adverse outcome. Prior stroke (P = .01) and prior CEA (P = .04) were significant for peri-procedural stroke. Design characteristics such as capture efficiency were associated with favorable outcomes. Conclusions Patients with prior CEA or stroke are more likely to have unfavorable CAS outcomes after 30 days. Filters with high capture efficiency may yield the best clinical results. Analysis of the effect of design characteristics on CAS outcome should aid the design of future devices. PMID:21530332

    The aim of the study was to use the appraisal model of stress to compare hemodialysis (HD) and continuous peritoneal dialysis (CAPD) patients with special focus on the perception of end-stage renal disease and subsequent emotional profile and health related quality of life (HQoL) in. We hypothesize that different circumstances related to both modes of therapies will result in dissimilar perception of chronic illness with subsequent changes in emotional profile and heath related quality of life. The total of 88 patients with end stage renal disease (ESRD) enrolled in hemodialysis (n=52; HD) or continuous peritoneal dialysis (n=36; CAPD) were given a battery of psychological tests: The Profile of Mood States, The Nottingham Health Profile, The Stress Situation Assessment Questionnaire, The Social Appreciation Questionnaire and The Situation and Trait and Anxiety Inventory. All patients perceived ESRD in terms of a loss and a threat. Moreover, CAPD patients evaluated ESRD as a challenge. Despite different perception of ESRD no significant difference in the level of fear, anxiety or emotional profile was found. Both HD and CAPD patient were reported more fatigue/inertia and confusion/bewilderment than control groups. The main health related complaints were similar in both ESRD patients with major complaints of sleeping disturbances, motor limitations and lack of energy. From the psychological point of view, CAPD treatment seems more like challenge to the enrolled patient which is positive outcome. Despite different appraisal of stress mood and health related complaints were similar in both groups. This may be a result of optimal regulation of cognitive perception of the stress depending on the circumstances of therapy. PMID:24516354

    Purpose: To report long-term outcomes of low- and intermediate-risk prostate cancer patients treated with high-dose hypofractionated radiation therapy (HypoRT). Methods and Materials: Patients with low- and intermediate-risk prostate cancer were treated using 3-dimensional conformal radiation therapy to a dose of 66 Gy in 22 daily fractions of 3 Gy without hormonal therapy. A uniform 7-mm margin was created around the prostate for the planning target volume, and treatment was prescribed to the isocenter. Treatment was delivered using daily ultrasound image-guided radiation therapy. Common Terminology Criteria for Adverse Events, version 3.0, was used to prospectively score toxicity. Biochemical failure was defined as the nadir prostate-specific antigen level plus 2 ng/mL. Results: A total of 129 patients were treated between November 2002 and December 2005. With a median follow-up of 90 months, the 5- and 8-year actuarial biochemical control rates were 97% and 92%, respectively. The 5- and 8-year actuarial overall survival rates were 92% and 88%, respectively. Only 1 patient died from prostate cancer at 92 months after treatment, giving an 8-year actuarial cancer-specific survival of 98%. Radiation therapy was well tolerated, with 57% of patients not experiencing any acute gastrointestinal (GI) or genitourinary (GU) toxicity. For late toxicity, the worst grade ≥2 rate for GI and GU toxicity was 27% and 33%, respectively. There was no grade >3 toxicity. At last follow-up, the rate of grade ≥2 for both GI and GU toxicity was only 1.5%. Conclusions: Hypofractionation with 66 Gy in 22 fractions prescribed to the isocenter using 3-dimensional conformal radiation therapy produces excellent biochemical control rates, with moderate toxicity. However, this regimen cannot be extrapolated to the intensity modulated radiation therapy technique.

    This cross-sectional, case control study examines the association between child sexual abuse and interpersonal and intrapersonal outcomes among 54 adolescents, examining specific clinical measures (depression, anxiety, dissociation, and posttraumatic stress disorder, attachment patterns, self-esteem, self-disclosure, and family environment characteristics). The research results point to a correlation between sexual abuse and higher levels of the clinical measures. In addition, a correlation was found between sexual abuse and level of avoidant attachment, self-esteem, and family environment characteristics. Stepwise hierarchical regressions were conducted to examine how adolescent attributes predicted depression, anxiety, and dissociation beyond the prediction based on sexual abuse. A combination of self-esteem, anxiety attachment, and family cohesiveness made sexual abuse insignificant when predicting levels of depression, anxiety, and dissociation. This study contributes to characterizing the emotional, personal, and family attributes of adolescents who experienced sexual abuse. It also raises questions about the clinical outcomes usually associated with sexual abuse.

    Patient-generated reports, also known as Patient-Reported Outcomes (PROs), capture the patients' illness experience in a structured format and may help bridge the gap between patients and providers. PROs measure any aspect of patient-reported health (e.g., physical, emotional or social symptoms) and can help to direct care and improve clinical outcomes. When clinicians systematically collect patient-reported data in the right place at the right time, PRO measurement can effectively aid in detection and management of conditions, improve satisfaction with care and enhance the patient-provider relationship. This review article summarizes the latest approaches to PRO measuring for clinical trials and clinical practice, with a focus on use of PROs in gastroenterology.

    In June 2012, Alberta Health Services introduced Strategic Clinical Networks (SCNs) as engines of innovation. The SCNs are collaborative clinical teams, with a provincial strategic mandate and with goals of achieving best outcomes, seeking greatest value for money and engaging clinicians in all aspects of the work. The SCNs are led by clinicians, driven by clinical needs, based on measurement and best evidence, and supported by research expertise, infrastructure, quality improvement, and analytic resources. Eleven SCNs are operational, with five others planned. Early measurable value is demonstrable in each. Examples include improving care and outcomes following stroke, reducing use of anti-psychotics in Long-Term Care (LTC), and improving surgical safety through effective implementation of the Safe Surgery Checklist. © 2015 The Canadian College of Health Leaders.

  11. Possible clinical outcome measures for clinical trials in patients with multiple sclerosis

    Multiple sclerosis (MS) is a chronic inflammatory and neurodegenerative disease with both clinical and pathological heterogeneity. The complexity of the MS population has offered challenges to the measurement of MS disease progression in therapeutic trials. The current standard clinical outcome measures are relapse rate, Expanded Disability Severity Scale (EDSS), and the MS Functional Composite (MSFC). These measures each have strengths and some weakness. Two additional measures, the six-minute walk and accelerometry, show promise in augmenting current measures. MS therapeutics is a quickly advancing field which requires sensitive clinical outcome measures that can detect small changes in disability that reliably reflect long-term changes in sustained disease progression in a complex population. A single clinical outcome measure of sustained disease progression may remain elusive. Rather, an integration of current and new outcome measures may be most appropriate and utilization of different measures depending on the MS population and stage of the disease may be preferred.

    The aim of this review was to evaluate the clinical outcomes for the different time points of implant placement following tooth extraction. A PubMed search and a hand search of selected journals were performed to identify clinical studies published in English that reported on outcomes of implants in postextraction sites. Only studies that included 10 or more patients were accepted. For implant success/survival outcomes, only studies with a mean follow-up period of at least 12 months from the time of implant placement were included. The following outcomes were identified: (1) change in peri-implant defect dimension, (2) implant survival and success, and (3) esthetic outcomes. Of 1,107 abstracts and 170 full-text articles considered, 91 studies met the inclusion criteria for this review. Bone augmentation procedures are effective in promoting bone fill and defect resolution at implants in postextraction sites, and are more successful with immediate (type 1) and early placement (type 2 and type 3) than with late placement (type 4). The majority of studies reported survival rates of over 95%. Similar survival rates were observed for immediate (type 1) and early (type 2) placement. Recession of the facial mucosal margin is common with immediate (type 1) placement. Risk indicators included a thin tissue biotype, a facial malposition of the implant, and a thin or damaged facial bone wall. Early implant placement (type 2 and type 3) is associated with a lower frequency of mucosal recession compared to immediate placement (type 1).

    aHUS is a clinical challenge for successful renal transplantation. A 14-yr-old girl lost her kidneys at the age of 7, due to CFH antibodies and CFH-related protein (CFHR1/CFHR3) homozygous deletion-associated aHUS. CFH, CFI, and MCP gene mutations were excluded. The patient was a candidate for renal transplantation despite persistent presence of CFH antibodies (up to 539 AU/mL). Treatment with MMF, IVIG, and repeated PF (n = 8) was introduced while being placed on urgent waiting list. Three years after aHUS onset, the patient underwent the deceased donor renal transplantation "under cover" of PF, as PF was performed directly prior to surgery and, then, PFs were repeated up to overall 14 sessions. Quadruple immunosuppression (basiliximab + tacrolimus + MMF + prednisolone) was used. Moderate symptoms of aHUS (hemolysis, low platelets, and low C3) were present within first seven days post-transplant and then normalized with PF therapy. The patient remained stable during four yr of further follow-up after transplantation. Specific pre- and post-transplant management allowed successful renal transplantation in a CFH antibody-positive patient. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Recent discoveries have highlighted the novel metabolic functions of adipose tissue in enhancing hypermetabolism after trauma. As the exact function and expression profiles of serum lipids and free fatty acids (FFA) are essentially unknown, we determined the lipidomic expression profile after burn in correlation to clinical outcomes to identify important lipid mediators affecting post-burn outcomes. We conducted a prospective cohort study with 46 adult burn patients and 5 healthy controls at the Ross Tilley Burn Center in Toronto, Canada. Patients were stratified based on major demographic and clinical variables, including age, burn severity, mortality, and sepsis. Serum FFAs and inflammatory markers were measured during acute hospital stay. We found that FFAs were acutely elevated post-burn and returned to baseline over time. Greater burn severity and age were associated with an impaired acute response in unsaturated FFAs and pro-inflammatory cytokines. Elevations in saturated and mono-unsaturated FFAs correlated significantly to increased mortality. In summary, persistent elevation of unsaturated lipids was associated with a functionally altered inflammatory-immunological milieu and worse clinical outcomes. The present lipidomic analysis indicates profound alterations in the lipid profile after burn by characterizing key lipids as potential diagnostic and outcome indicators in critically injured patients.

    This study examined the effectiveness of the clinical teaching associate (CTA) model to improve clinical learning outcomes in nursing students. Students were randomly allocated to either the CTA (n = 28) or traditional training group (n = 32), and their clinical knowledge, skills, and satisfaction with the learning experience were assessed and compared. The results showed that the CTA model was equally effective in improving clinical knowledge, skills, and satisfaction of nursing students.

    To test the hypothesis that physicians' empathy is associated with positive clinical outcomes for diabetic patients. A correlational study design was used in a university-affiliated outpatient setting. Participants were 891 diabetic patients, treated between July 2006 and June 2009, by 29 family physicians. Results of the most recent hemoglobin A1c and LDL-C tests were extracted from the patients' electronic records. The results of hemoglobin A1c tests were categorized into good control (<7.0%) and poor control (>9.0%). Similarly, the results of the LDL-C tests were grouped into good control (<100) and poor control (>130). The physicians, who completed the Jefferson Scale of Empathy in 2009, were grouped into high, moderate, and low empathy scorers. Associations between physicians' level of empathy scores and patient outcomes were examined. Patients of physicians with high empathy scores were significantly more likely to have good control of hemoglobin A1c (56%) than were patients of physicians with low empathy scores (40%, P < .001). Similarly, the proportion of patients with good LDL-C control was significantly higher for physicians with high empathy scores (59%) than physicians with low scores (44%, P < .001). Logistic regression analyses indicated that physicians' empathy had a unique contribution to the prediction of optimal clinical outcomes after controlling for physicians' and patients' gender and age, and patients' health insurance. The hypothesis of a positive relationship between physicians' empathy and patients' clinical outcomes was confirmed, suggesting that physicians' empathy is an important factor associated with clinical competence and patient outcomes.

    Contrary to the situation in early breast cancer, little is known about the prognostic relevance of the hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2) in metastatic breast cancer. The objectives of this study were to present survival estimates and to determine the prognostic impact of breast cancer subtypes based on HR and HER2 status in a recent cohort of metastatic breast cancer patients, which is representative of current clinical practice. Patients diagnosed with metastatic breast cancer between 2007 and 2009 were included. Information regarding patient and tumor characteristics and treatment was collected. Patients were categorized in four subtypes based on the HR and HER2 status of the primary tumor: HR positive (+)/HER2 negative (-), HR+/HER2+, HR-/HER2+ and triple negative (TN). Survival was estimated using the Kaplan-Meier method. Cox proportional hazards model was used to determine the prognostic impact of breast cancer subtype, adjusted for possible confounders. Median follow-up was 21.8 months for the 815 metastatic breast cancer patients included; 66 % of patients had the HR+/HER2- subtype, 8 % the HR-/HER2+ subtype, 15 % the TN subtype and 11 % the HR+/HER2+ subtype. The longest survival was observed for the HR+/HER2+ subtype (median 34.4 months), compared to 24.8 months for the HR+/HER2- subtype, 19.8 months for the HR-/HER2+ subtype and 8.8 months for the TN subtype (P < 0.0001). In the multivariate analysis, subtype was an independent prognostic factor, as were initial site of metastases and metastatic-free interval. The HR+/HER2+ subtype was associated with the longest survival after diagnosis of distant metastases.

    Scorpion envenomation is a health problem in children in tropical and subtropical regions. The aim of this study was to evaluate demographic and clinical characteristics as well as outcomes in referred children to Assiut University Children Hospital during the year 2012 with a history of scorpion sting. The medical files of these patients were reviewed retrospectively for demographic data, time and site of biting, and clinical manifestations. Laboratory investigations of the patients were reviewed for complete blood count (CBC), liver function tests, creatinine phosphokinase (CPK), lactate dehydrogenase (LDH), arterial blood gases, and serum electrolytes. Results showed 111 children with a history of scorpion sting; 69 males and 42 females with a median age of 5 years. Out of the studied patients, 53.2 % were classified as class III of clinical severity with recorded pulmonary edema in 33.3 %, cardiogenic shock in 46.8 %, and severe neurological manifestations in 22.8 %. Twelve patients (10.8 %) were classified as class II with mild systemic manifestations, and 36 % of the patients were classified as class I with only local reaction. Outcomes of these patients were discharge without sequelae in 55.8 %, discharge with sequelae in 26.1 %, and death in 18.1 %. more than half of stung children had a severe clinical presentation and about one fifth died. Aggressive treatment regimens are recommended for such patients to improve the outcome.

    Objective Progress in basic neuroscience has led to identification of molecular targets for treatment in fragile X syndrome (FXS) and other neurodevelopmental disorders, however, there is a gap in translation to targeted therapies in humans. One major obstacle to the demonstration of efficacy in human trials has been the lack of generally accepted endpoints to assess improvement in function in individuals with FXS. To address this problem, the NIH convened a meeting of leading scientists and clinicians with the goal of identifying and standardizing outcome measures for use as potential endpoints in clinical trials in FXS. Methods Participants in the meeting included FXS experts, experts in the design and implementation of clinical trials and measure development, and representatives from advocacy groups, industry, and federal agencies. Results The group generated recommendations for optimal outcome measures in cognitive, behavioral, and biomarker/medical domains, including additional testing and validation of existing measures, and development of new measures in areas of need. Although no one endpoint or set of endpoints could be identified that met all criteria as an optimal measure, recommendations are presented in this report. Conclusion The report is expected to guide the selection of measures in clinical trials and lead to the use of a more consistent battery of measures across trials. Further, this will help to direct research toward gaps in the development of validated FXS-specific outcome measures, and to assist with interpretation of clinical trial data by creating templates for measurement of treatment efficacy.

    Objectives: Vestibular schwannomas are the hallmark of neurofibromatosis 2 (NF2), occurring in >95% of patients. These tumors develop on the vestibulocochlear nerve and are associated with significant morbidity due to hearing loss, tinnitus, imbalance, facial weakness, and risk of early mortality from brainstem compression. Although hearing loss and facial weakness have been identified as important functional outcomes for patients with NF2, there is a lack of consensus regarding appropriate endpoints in clinical trials. Methods: The functional outcomes group reviewed existing endpoints for hearing and facial function and developed consensus recommendations for response evaluation in NF2 clinical trials. Results: For hearing endpoints, the functional group endorsed the use of maximum word recognition score as a primary endpoint, with the 95% critical difference as primary hearing outcomes. The group recommended use of the scaled measurement of improvement in lip excursion (SMILE) system for studies of facial function. Conclusions: These recommendations are intended to provide researchers with a common set of endpoints for use in clinical trials of patients with NF2. The use of common endpoints should improve the quality of clinical trials and foster comparison among studies for hearing loss and facial weakness. PMID:24249803

    Objective Standard outcome measures used for amyotrophic lateral sclerosis (ALS) clinical trials, including the ALS Functional Rating Scale-revised (ALSFRS-R), maximal voluntary isometric contraction testing (MVICT), and manual muscle testing (MMT) are limited in their ability to detect subtle disease progression. Electrical impedance myography (EIM) is a new non-invasive technique that provides quantitative data on muscle health by measuring localized tissue impedance. This study investigates whether EIM could provide a new outcome measure for use in ALS clinical trials work. Methods Fifteen ALS patients underwent repeated EIM measurements of one or more muscles over a period of up to 18 months and the primary outcome variable, θz-max, measured. The θz-max megascore was then calculated using the same approach as has been applied in the past for MVICT. This and the MMT data were then used to assess each measure’s statistical power to detect a given effect on disease progression in a hypothetical planned clinical therapeutic trial. Results θz-max showed a mean decline of about 21% for the test period, averaged across all patients and all tested muscles. The θz-max megascore had a power of 73% to detect a 10% treatment effect in our planned hypothetical trial, as compared to a 28% power for MMT. These results also compared favorably to historical data for ALSFRS-R and MVICT arm megascore from the trial of celecoxib in ALS, where both measures had only a 23% power to detect the same 10% treatment effect. Conclusions The θz-max megascore may provide a powerful new outcome measure for ALS clinical trials. Significance The application of EIM to future ALS trials may allow for smaller, faster studies with an improved ability to detect subtle treatment effects. PMID:17897874

    Research on and commercial development of the artificial pancreas (AP) continue to progress rapidly, and the AP promises to become a part of clinical care. In this report, members of the JDRF Artificial Pancreas Project Consortium in collaboration with the wider AP community 1) advocate for the use of continuous glucose monitoring glucose metrics as outcome measures in AP trials, in addition to HbA1c, and 2) identify a short set of basic, easily interpreted outcome measures to be reported in AP studies whenever feasible. Consensus on a broader range of measures remains challenging; therefore, reporting of additional metrics is encouraged as appropriate for individual AP studies or study groups. Greater consistency in reporting of basic outcome measures may facilitate the interpretation of study results by investigators, regulatory bodies, health care providers, payers, and patients themselves, thereby accelerating the widespread adoption of AP technology to improve the lives of people with type 1 diabetes.

    2014-01-01

    Objective Multilevel models have become a standard data analysis approach in intervention research. Although the vast majority of intervention studies involve multiple outcome measures, few studies use multivariate analysis methods. The authors discuss multivariate extensions to the multilevel model that can be used by psychotherapy researchers. Method and Results Using simulated longitudinal treatment data, the authors show how multivariate models extend common univariate growth models and how the multivariate model can be used to examine multivariate hypotheses involving fixed effects (e.g., does the size of the treatment effect differ across outcomes?) and random effects (e.g., is change in one outcome related to change in the other?). An online supplemental appendix provides annotated computer code and simulated example data for implementing a multivariate model. Conclusions Multivariate multilevel models are flexible, powerful models that can enhance clinical research. PMID:24491071

    Daptomycin use at our institution changed to ideal body weight dosing based on a published analysis of pharmacokinetic-pharmacodynamic efficacy target attainment, bacterial ecology, and a desire to reduce drug toxicity. The current study compared outcomes between actual body weight and ideal body weight dosing of daptomycin before and after this intervention. In the evaluable group, 69 patients received doses based on actual body weight and 48 patients received doses based on ideal body weight. Patients were treated for documented Enterococcus species, Staphylococcus aureus, or coagulase-negative Staphylococcus infections, including bloodstream, intraabdominal, skin and soft tissue, urinary, and bone. There was no statistically significant difference in clinical success between the groups (88.9% for actual body weight compared to 89.1% for ideal body weight, P = 0.97). After we adjusted for gender, age, body mass index, concomitant 3-hydroxy-3-methylglutaryl–coenzyme A reductase inhibitors, infection type, and organism type, clinical success rates remained similar between groups (adjusted odds ratio of 0.68 in favor of actual body weight, 95% confidence interval [CI] of 0.13 to 3.55). Microbiological outcomes, length of stay, mortality, and adverse effects were also similar between groups. Further studies are warranted to confirm that ideal body weight dosing provides similar outcomes to actual body weight dosing for all patients and types of infections and organisms. PMID:24145531

    Introduction Oedema is observed frequently following surgery and may be associated with worse outcomes. To date, no study has investigated the role of oedema in the emergency surgical patient. This study assesses the incidence of oedema following emergency abdominal surgery and the value of early postoperative oedema measurement in predicting clinical outcome. Methods A prospective cohort study of patients undergoing emergency abdominal surgery at a university unit over a two-month period was undertaken. Nutritional and clinical outcome data were collected and oedema was measured in the early postoperative period. Predictors of oedema and outcomes associated with postoperative oedema were identified through univariate and multivariate analysis. Results Overall, 55 patients (median age: 66 years) were included in the study. Postoperative morbidity included ileus (n=22) and sepsis (n=6) with 12 deaths at follow-up. Postoperative oedema was present in 19 patients and was associated with prolonged perioperative fasting (107 vs 30 hours, p=0.009) but not with body mass index (24kg/m2 vs 27kg/m2, p=0.169) or preadmission weight loss (5% vs 3%, p=0.923). On multivariate analysis, oedema was independently associated with gastrointestinal recovery (B=6.91, p=0.038), artificial nutritional support requirement (odds ratio: 6.91, p=0.037) and overall survival (χ2=13.1, df=1, p=0.001). Conclusions Generalised oedema is common after emergency abdominal surgery and appears to independently predict gastrointestinal recovery, the need for artificial nutritional support and survival. Oedema is not associated with commonly applied markers of nutritional status such as body mass index or recent weight loss. Measurement of oedema offers utility in identifying those at risk of poor clinical outcome or those requiring artificial nutritional support following emergency abdominal surgery. PMID:24025285

Postoperative oedema was present in 19 patients and was associated with prolonged perioperative fasting (107 vs 30 hours, p=0.009) but not with body mass index (24 kg/m(2) vs 27 kg/m(2), p=0.169) or preadmission weight loss (5% vs 3%, p=0.923). On multivariate analysis, oedema was independently associated with gastrointestinal recovery (B=6.91, p=0.038), artificial nutritional support requirement (odds ratio: 6.91, p=0.037) and overall survival (χ(2) =13.1, df=1, p=0.001). Generalised oedema is common after emergency abdominal surgery and appears to independently predict gastrointestinal recovery, the need for artificial nutritional support and survival. Oedema is not associated with commonly applied markers of nutritional status such as body mass index or recent weight loss. Measurement of oedema offers utility in identifying those at risk of poor clinical outcome or those requiring artificial nutritional support following emergency abdominal surgery.

    Cystic fibrosis (CF) is a common inherited condition caused by mutations in the gene encoding the CF transmembrane regulator protein. With increased understanding of the molecular mechanisms underlying CF and the development of new therapies there comes the need to develop new outcome measures to assess the disease, its progression and response to treatment. As there are limitations to the current endpoints accepted for regulatory purposes, a workshop to discuss novel endpoints for clinical trials in CF was held in Anaheim, California in November 2011. The pros and cons of novel outcome measures with potential utility for evaluation of novel treatments in CF were critically evaluated. The highlights of the 2011 workshop and subsequent advances in technologies and techniques that could be used to inform the development of clinical trial endpoints are summarized in this review.

    Severe acute respiratory syndrome (SARS) poses a major threat to the health of people worldwide. We performed a retrospective case series analysis to assess clinical outcome and identify pretreatment prognostic correlates of SARS, managed under a standardized treatment protocol. We studied 127 male and 196 female patients with a mean age of 41±14 (range 18–83). All patients, except two, received ribavirin and steroid combination therapy. In 115 (36%) patients, the course of disease was limited. Pneumonitis progressed rapidly in the remaining patients. Sixty-seven (21%) patients required intensive care, and 42 (13%) required ventilator support. Advanced age, high admission neutrophil count, and high initial lactate dehydrogenase level were independent correlates of an adverse clinical outcome. SARS-associated coronavirus caused severe illnesses in most patients, despite early treatment with ribavirin and steroid. This study has identified three independent pretreatment prognostic correlates. PMID:14519241

    Increasingly individuals with intellectual and developmental disabilities, including Down syndrome, are being targeted for clinical trials. However, a challenge exists in effectively evaluating the outcomes of these new pharmacological interventions. Few empirically evaluated, psychometrically sound outcome measures appropriate for use in clinical trials with individuals with Down syndrome have been identified. To address this challenge, the National Institutes of Health (NIH) assembled leading clinicians and scientists to review existing measures and identify those that currently are appropriate for trials; those that may be appropriate after expansion of age range addition of easier items, and/or downward extension of psychometric norms; and areas where new measures need to be developed. This article focuses on measures in the areas of cognition and behavior.

    Purpose: Arthroscopic transosseous (TO) rotator cuff repair has recently emerged as a new option for surgical treatment of symptomatic rotator cuff tears. Limited data is available regarding outcomes using this technique. This study evaluated midterm clinical outcomes following a novel arthroscopic TO (anchorless) rotator cuff repair technique. Materials and Methods: A consecutive series of 107 patients and 109 shoulders underwent arthroscopic TO (anchorless) rotator cuff repair for a symptomatic full-thickness tear. Pre and postoperative range of motion (ROM) was compared at an average of 11.8 months. Postoperative outcome scores were obtained at an average of 38.0 months. Statistical analysis was performed to compare pre and postoperative ROM data. Univariate analysis was performed using Student's t-test to compare the effect of other clinical characteristics on final outcome. Results: Statistically significant improvements were noted in forward flexion, external rotation and internal rotation (P < 0.0001). Average postoperative subjective shoulder value was 93.7, simple shoulder test 11.6, and American Shoulder and Elbow Surgeons (ASES) score 94.6. According to ASES scores, results for the 109 shoulders available for final follow-up were excellent in 95 (87.1%), good in 8 (7.3%), fair in 3 (2.8%), and poor in 3 (2.8%). There was no difference in ROM or outcome scores in patients who underwent a concomitant biceps procedure (tenodesis or tenotomy) compared with those who did not. Furthermore, there was no significant difference in outcome between patients who underwent either biceps tenodesis or tenotomy. Age, history of injury preceding the onset of pain, tear size, number of TO tunnels required to perform the repair, and presence of fatty infiltration did not correlate with postoperative ROM or subjective outcome measures at final follow-up. Two complications and four failures were noted. Conclusions: Arthroscopic TO rotator cuff repair technique leads to

    We describe the features and outcomes of neonatal pertussis and compare these with neonates with non-pertussis acute respiratory illness from July 2000 through December 2007. Patients with pertussis had a more severe course of disease as evidenced by the clinical presentation, length of hospitalization, and oxygen requirement. Clinicians should have a high index of suspicion so that appropriate supportive care can be initiated promptly.

    Objective To determine if premature infants with invasive Candida infection caused by strains with increased virulence properties have worse clinical outcomes than those infected with less virulent strains. Study design Clinical isolates were studied from 2 populations; premature infants colonized with Candida (commensal, n=27), and those with invasive candidiasis (n=81). Individual isolates of C. albicans and C. parapsilosis were tested for virulence in each of 3 assays: phenotypic switching, adhesion, and cytotoxicity. Invasive isolates were considered to have enhanced virulence if they measured more than 1 SD above the mean for the commensal isolates in at least 1 assay. Outcomes of patients with invasive isolates with enhanced virulence were compared with those with invasive isolates lacking enhanced virulence characteristics. Results 61% of invasive isolates of C. albicans and 42% of invasive isolates of C. parapsilosis had enhanced virulence. All C. albicans cerebrospinal fluid (CSF) isolates (n=6) and 90% of urine isolates (n=10) had enhanced virulence, compared with 48% of blood isolates (n=40). Infants with more virulent isolates were younger at the time of positive culture and had higher serum creatinine. Conclusions Individual isolates of Candida species vary in their virulence properties. Strains with higher virulence are associated with certain clinical outcomes. PMID:22504098

    The natural history of AA amyloidosis is typically progressive, leading to multiple organ failure and death. We analyzed the etiology as well as clinical and laboratory features of patients with biopsy-proven AA amyloidosis and evaluated the ultimate outcome. Seventy-three patients (24 female; mean age 41.85±15.89 years) were analyzed retrospectively. Demographic, clinical and laboratory features were studied and the outcome was assessed. Familial Mediterranean Fever and tuberculosis were the most frequent causes of amyloidosis. Mean serum creatinine and proteinuria at diagnosis were 4.65±4.89 mg/dl and 8.04±6.09 g/day, respectively; and stage I, II, III, IV and V renal disease were present in 19.2%, 13.7%, 16.4%, 11%, and 39.7% of the patients, respectively. ESRD developed in 16 patients during the follow-up period. All of the ESRD patients started a dialysis programme. Thirty patients (41%) died during the follow-up period; median patient survival was 35.9±6.12 months. Old age, tuberculosis etiology, advanced renal disease and low serum albumin levels were associated with a worse prognosis. Serum albumin was a predictor of mortality in logistic regression analysis. The ultimate outcome of the patients with AA amyloidosis is poor, possibly due to the late referral to the nephrology clinics. Early referral may be helpful to improve prognosis. Copyright © 2013 S.

    Modern interest in patient-reported outcomes measures (PROMs) in orthopaedics dates back to the mid-1980s. While gradual growth of activity in this area has occurred over the past 25 years, the extent to which this research methodology is applied in clinical practice to improve patient care is unclear. WHERE ARE WE NOW?: Historically, clinical research in orthopaedics has focused on the technical success of treatment, and objective indicators such as mortality, morbidity, and complications. By contrast, the PROMs framework focuses on effects of treatment described in terms of relief of symptoms, restoring functional ability, and improving quality of life. PROMs can be used to study the relative effects of disease, injury, and treatment across different health conditions. WHERE DO WE NEED TO GO?: All clinical research should begin with identifying clear and meaningful research questions so that the resources and efforts required for data collection result in useful data. Different consumers of research data have different perspectives on what comprises meaningful information. Involving stakeholders such as patients, providers, payers, and policy-makers when defining priorities in the larger research endeavor is one way to inform what type of data should be collected in a particular study. HOW DO WE GET THERE?: Widespread collection of outcomes data would potentially aid these stakeholders by identifying best practices, benefits and costs, and important patient or practice characteristics related to outcomes. Several initiatives currently underway may help systematic collection of PROMs, create efficient systems, and foster collaborations to provide support and resources to minimize costs.

    Identification of tumor driver mutations is crucial for improving clinical outcome using a personalized approach to the treatment of cancer. Neuroblastoma is a tumor of the peripheral sympathetic nervous system for which only a few driver alterations have been described including MYCN amplification and ALK mutations. We assessed 106 primary neuroblastoma tumors by next generation sequencing using a customized amplicon-based gene panel. Our results reveal that genetic variants in TIAM1 gene associate with better clinical outcome, suggesting a role for these TIAM1 variants in preventing progression of this disease. The detected variants are located within the different domains of TIAM1 that signal to the upstream regulator RAS and downstream effector molecules MYC and RAC, which are all implicated in neuroblastoma etiology and progression. Clinical outcome was improved in tumors where a TIAM1 variant was present concomitantly with either ALK mutation or MYCN amplification. Given the function of these signaling molecules in cell survival, proliferation, differentiation and neurite outgrowth, our data suggest that the TIAM1-mediated network is essential to neuroblastoma and thus, inhibiting TIAM1 reflects a rational strategy for improving therapy efficacy in neuroblastoma.

    Despite numerous potential health outcomes of dog guardianship, their value has not been examined in the HIV-positive population. The study objective was to examine the relationship between dog guardianship and HIV clinical outcomes (antiretroviral adherence [≥95% versus <95%], HIV viral load [≥48copies/mL versus <48copies/mL], and CD4+ cell count) among HIV-positive individuals. We conducted a secondary analysis of baseline data of 370 HIV-positive men on antiretrovirals enrolled in the Duo Project. Generalized estimating equations were used for inferential regression analyses, while controlling for the focal dog guardianship variable and non-focal covariates. Current dog guardianship was reported in 28.7% of participants. Dog guardianship may be associated with higher CD4+ (coefficient=60.6, p=0.052) and adherence ≥95% (OR=1.80, p=0.048); however, having a detectable viral load was not related to dog guardianship (OR=0.94, p=0.85). Further clinical research with detailed dog guardianship data is needed to further examine the association between dog guardianship and HIV clinical outcomes. PMID:25436253

    Cardiac resynchronization therapy (CRT) improves functional outcomes in patients with severe systolic heart failure. Whether the effects of CRT on left ventricular (LV) diastolic function and clinical outcomes are influenced by the cause as either ischemic or nonischemic cardiomyopathy (CM) has not been well established. A total of 57 patients (age 60 +/- 11 years; 25% women; LV ejection fraction 25 +/- 5%) were studied before and 4 +/- 2 months after CRT by echocardiography. Heart failure cause was ischemic CM in 19 and nonischemic CM in 38. Measurements of LV systolic and diastolic function were determined by 2-dimensional and Doppler echocardiography with Doppler tissue imaging of regional myocardial velocities. Clinical outcome events were assessed at long-term follow-up and included hospitalization for heart failure exacerbation, heart transplantation, or cardiac-related death. There were significant increases in LV ejection fraction, reductions in end-systolic volumes, and improved LV systolic dyssynchrony in both groups. However, significant improvements in LV diastolic function were observed only in the patients with nonischemic CM. Clinical events occurred in 53% of the ischemic group versus 26% of the nonischemic group (P < .05) after 20 +/- 11 months of CRT. Univariate and multivariate analysis revealed that Doppler-estimated LV filling pressures were predictors of clinical outcome events. After CRT patients with ischemic CM exhibit lack of improvement in LV diastolic function despite favorable effects on LV systolic performance. The Doppler-derived LV filling indices may be an important predictor of long-term clinical outcomes after CRT.

    The future of nuclear medicine procedures, as understood within our current economic climate, depends upon its ability to provide relevant clinical information at similar or lower comparative costs. With an ever-increasing emphasis on cost containment, outcome assessment forms the basis of preserving the quality of patient care. Today, outcomes assessment encompasses a wide array of subjects including clinical, economic, and humanistic (i.e., quality of life) outcomes. For nuclear cardiology, evidence-based medicine would require a threshold level of evidence in order to justify the added cost of any test in a patient's work-up. This evidence would include large multicenter, observational series as well as randomized trial data in sufficiently large and diverse patient populations. The new movement in evidence-based medicine is also being applied to the introduction of new technologies, in particular when comparative modalities exist. In the past 5 years, we have seen a dramatic shift in the quality of outcomes data published in nuclear cardiology. This includes the use of statistically rigorous risk-adjusted techniques as well as large populations (i.e., > 500 patients) representing multiple diverse medical care settings. This has been the direct result of the development of multiple outcomes databases that have now amassed thousands of patients worth of data. One of the benefits of examining outcomes in large patient datasets is the ability to assess individual endpoints (e.g., cardiac death) as compared with smaller datasets that often assess combined endpoints (e.g., death, myocardial infarction, or unstable angina). New technologies for the diagnosis of coronary artery disease have contributed to the rising costs of care. In the United States and in Europe, costs of care have risen dramatically, consuming an ever-increasing amount of available resources. The overuse of diagnostic angiography often leads to unnecessary revascularization that does not lead to

Main outcomes were the clinical, ultrasonic, and microbiological characteristics of the canalicular concretions; the histopathologic profiles; and the treatment effect.Thirty-six patients were identified with concretions in all 37 cases of the patients with canaliculitis. There were 30 (83.3%) female patients with a mean age of 54.2 years. Twenty-eight (77.8%) patients were misdiagnosed or delayed diagnosed, and the mean duration was 17.1 months. The common most clinical presentations were discharge (100%), epiphora (66.7%), erythema (52.8%), and swelling (47.2%), and concretions were found in 31 of 37 patients by typical clinical manifestations and in 5 of 6 patients by ultrasonic. Actinomyces was found in 8 of 13 histopathologic specimens, and microbiological cultures were positive in 13 of 24 patients. All patients underwent canaliculotomy with curettage to completely remove all concretions and contents; 35 of 36 patients' symptoms improved and 1 recurred after treatment at a median of 21.7 months follow-up according to the telephonic questionnaires.Canalicular concretions play an important role in primary canaliculitis. Canaliculotomy with curettage is a standard therapy with canalicular concretions, and the surgical removal of all possible concretions is essential for cure.

    Pancreas dissociation is a critical initial component of the islet isolation procedure and introduces high variability based on factors including the enzyme type, specificity and potency. Product refinement and alterations to the application strategies have improved isolation outcomes over time; however, islet utilization from donor organs remains low. In this study we evaluate a low endotoxin-high activity grade neutral protease in clinical islet isolation. The use of a non-collagenolytic enzyme, either thermolysin or high active neutral protease, was randomized in clinical islet isolations to evaluate efficacy. Additionally a retrospective comparison to neutral protease NB was conducted. The thermolysin group had lower trapped islet population and increased purity and post-culture islet mass in comparison to high active grade neutral protease. Comparison of neutral protease NB GMP grade to high active neutral protease displayed no measurable difference in islet mass or viability and transplantation outcomes at 1 mo post-transplant were favorable for both groups. High activity neutral protease can generate clinical grade islets and may prove beneficial to islet function and viability based on a reduced endotoxin load but dosing of neutral protease requires ongoing optimization.

  6. Likelihood of Being Helped or Harmed as a Measure of Clinical Outcomes in Psychopharmacology.

    The likelihood of being helped or harmed (LHH) ratio is an indirect measure of effect size. It tells the reader how much as likely a patient is to benefit from a treatment as to suffer from an adverse outcome with that treatment; larger values for LHH indicate more favorable treatment outcomes. The numerator for LHH is usually a measure of response or remission with a treatment, and the denominator is usually a measure of all-cause discontinuation or discontinuation due to adverse events; so, there can be more than 1 LHH statistic for a study. As an example, an LHH of 5 could indicate that after removal of placebo effects a patient is 5 times as likely to respond to a treatment as to drop out of treatment because of the experience of an adverse event. This article explains the LHH with the help of a worked example, shows how the LHH can be derived from the numbers needed to treat and harm (NNT, NNH) statistics, discusses practical issues related to the concept, and considers its limitations. The LHH is little used in clinical psychopharmacology, and authors who report or review clinical trial data should consider presenting all the LHH information that is clinically relevant in addition to NNT, NNH, and other information. Because LHH statistics present the results of risk-benefit trade-off analyses, they can help clinicians and patients more easily evaluate potential treatments during decision-making processes.

    Despite a huge number of published laboratory bonding studies on dental oxide ceramics clinical long-term studies on resin bonded oxide ceramic restorations are rare. The purpose of this review is to present the best available clinical evidence for successful bonding of dental oxide ceramic restorations. Clinical trials with resin-bonded restorations that had no or only limited mechanical retention and were made from alumina or zirconia ceramic were identified using an electronic search in PubMed database. Overall 10 publications with clinical trials could be identified. Their clinical outcome was compared with that laboratory bond strength studies. Clinical data provide strong evidence that air-abrasion at a moderate pressure in combination with using phosphate monomer containing primers and/or luting resins provide long-term durable bonding to glass-infiltrated alumina and zirconia ceramic under the humid and stressful oral conditions. As simple and clinically reliable bonding methods to oxide ceramics exist, the rationale for development of alternative bonding methods might be reconsidered especially when these methods are more time consuming or require rather complicated and/or technique sensitive procedures.

    Background Despite extensive research on gender differences in addiction, there are relatively few published reports comparing treatment outcomes for women versus men based on evidence-based treatments evaluated in randomized clinical trials. Methods An aggregate sample comprised of data from five randomized clinical trials of treatment for cocaine dependence (N = 434) was evaluated for gender differences in clinical outcomes. Secondary analyses compared gender differences in outcome by medication condition (disulfiram versus no medication) and across multiple behavioral treatment conditions. Results Women, compared with men, had poorer treatment outcomes on multiple measures of cocaine use during treatment and at post-treatment follow-up. These results appear to be primarily accounted for by disulfiram being less effective in women compared with men. There was no evidence of meaningful gender differences in outcome as a function of the behavioral therapies evaluated. Conclusions These findings suggest that women and men may benefit to similar degrees from some empirically validated behavioral treatments for addiction. Conversely, some addiction pharmacotherapies, such as disulfiram, may be associated with poorer outcomes among women relative to men and point to the need for careful assessment of pharmacological treatments in both sexes prior to widespread clinical implementation.

    Macrolide antibiotics are cornerstones in the treatment of Mycobacterium massiliense lung disease. Despite the emergence of resistance, limited data on macrolide-resistant M massiliense lung disease are available. This study evaluated the clinical features and treatment outcomes of patients and the molecular characteristics of macrolide-resistant M massiliense isolates. We performed a retrospective review of medical records and genetic analyses of clinical isolates from 15 patients who had macrolide-resistant M massiliense lung disease between September 2005 and February 2015. Nine patients (60%) had the nodular bronchiectatic form of the disease, and six (40%) had the fibrocavitary form. Before the detection of macrolide resistance, three patients (20%) were treated with macrolide monotherapy, four (27%) with therapy for presumed Mycobacterium avium complex infections, and eight (53%) with combination antibiotic therapy for M massiliense lung disease. The median treatment duration after the detection of resistance was 18.7 months (interquartile range, 11.2 to 39.8 months). Treatment outcomes were poor, with a favorable outcome being achieved for only one patient (7%), who underwent surgery in addition to antibiotic therapy. The 1-, 3-, and 5-year mortality rates were 7, 13, and 33%, respectively. Of the 15 clinical isolates, 14 (93%) had point mutations at position 2058 (n = 9) or 2059 (n = 5) of the 23S rRNA gene, resulting in macrolide resistance. Our study indicates that treatment outcomes are poor and mortality rates are high after the development of macrolide resistance in patients with M massiliense lung disease. Thus, preventing the development of macrolide resistance should be a key consideration during treatment.

This multicenter, hospital-based study included 6780 consecutive patients (aged, 69.9±12.2 years; 63.9% men) with ischemic stroke who were prospectively registered in Fukuoka, Japan, between July 2007 and December 2014. Onset-to-door time was categorized as T0-1, ≤1 hour; T1-2, >1 and ≤2 hours; T2-3, >2 and ≤3 hours; T3-6, >3 and ≤6 hours; T6-12, >6 and ≤12 hours; T12-24, >12 and ≤24 hours; and T24-, >24 hours. The main outcomes were neurological improvement (decrease in National Institutes of Health Stroke Scale score of ≥4 during hospitalization or 0 at discharge) and good functional outcome (3-month modified Rankin Scale score of 0-1). Associations between onset-to-door time and main outcomes were evaluated after adjusting for potential confounders using logistic regression analysis. Odds ratios (95% confidence intervals) increased significantly with shorter onset-to-door times within 6 hours, for both neurological improvement (T0-1, 2.79 [2.28-3.42]; T1-2, 2.49 [2.02-3.07]; T2-3, 1.52 [1.21-1.92]; T3-6, 1.72 [1.44-2.05], with reference to T24-) and good functional outcome (T0-1, 2.68 [2.05-3.49], T1-2 2.10 [1.60-2.77], T2-3 1.53 [1.15-2.03], T3-6 1.31 [1.05-1.64], with reference to T24-), even after adjusting for potential confounding factors including reperfusion treatment and basal National Institutes of Health Stroke Scale. These associations were maintained in 6216 patients without reperfusion treatment and in 4793 patients with minor stroke (National Institutes of Health Stroke Scale ≤4 on hospital arrival). Early hospital arrival within 6 hours after stroke onset is associated with favorable outcomes after ischemic stroke, regardless of

    Introduction Pulmonary aspergillosis has variable course of illness, severity and outcomes depending on underlying conditions. There is limited data available on the clinical manifestations and outcome of pulmonary aspergillosis from Pakistan. Methods To determine the clinical manifestations and outcome of pulmonary aspergillosis in a tertiary care hospital a retrospective study was conducted from 2004 to 2014 in patients admitted with pulmonary aspergillosis at the Aga Khan University Hospital Karachi, Pakistan. Results Of the 280 cases with provisional diagnosis of aspergillosis 69 met the inclusion criteria. The mean age was 45±15.7 years, 48 (69.6%) were men and 21 (30.4%) had diabetes mellitus (DM). The average length of hospital stay (LOS) was 10.61±9.08 days. Aspergillus fumigatus was the most common (42.0%), followed by Aspergillus flavus (28.9%). More than one-third of patients previously had tuberculosis (TB) (39.13%). The commonest pulmonary manifestation was chronic pulmonary aspergillosis (CPA) 47 (68.1%) followed by invasive pulmonary aspergillosis (IPA) 12 (17.4%) and subacute invasive aspergillosis (SAIA) 8 (11.6%). Surgical excision was performed in 28 patients (40.57%). Intensive care unit admission was required for 18 patients (26.08%). Case fatality rate was 14/69 (20.3%). DM, mean LOS and hypoxic respiratory failure were identified as independent risk factors of mortality on multivariate analysis. Conclusion A. fumigatus was the most frequent species found especially in patients with prior TB. CPA was the commonest pulmonary manifestation seen as post TB sequel. Diabetes, hypoxic respiratory failure and increased LOS were independent predictors of poor outcomes. Overall patients had good outcome with CPA compared with SAIA and IPA. PMID:28074136

    To evaluate the clinical outcomes of ruptured dermoid cysts. A multicenter, retrospective study of all cases of periorbital and orbital dermoid cysts with histopathological evidence of rupture, including those with clinical rupture, was performed over a 10-year period. Demographics and clinical outcomes of ruptured dermoid cysts were recorded. Persistent inflammation was defined as the presence of edema, erythema, and discomfort for at least 28 days. Eighty-six cases of dermoid cysts were identified. Median age was 5.5 (range, 1-63) years. Location of cyst was either periorbital (n = 60, 70%) or orbital (n = 26, 30%). There were 29 cases with clinically apparent rupture: 27 surgically ruptured (93%) and 2 spontaneous rupture (7%). Persistent inflammation was found in 1 spontaneous cyst rupture case (50%) and 1 surgically ruptured cyst (3.7%). Older age (p = 0.01) and bony attachment (p = 0.001) were significant factors for cyst rupture, while there was no influence from cyst location (p = 0.14). Persistent inflammation is uncommon after surgical rupture of dermoid cysts, but likely after spontaneous rupture. Older age and bony attachment are risk factors for cyst rupture.

    Purpose To determine differences in the clinical characteristics and antifungal susceptibility patterns among molecularly characterized ocular Fusarium sp isolates. Methods 58 Fusarium isolates obtained from 52 eyes of 52 patients were retrieved from the Bascom Palmer Eye Institute’s (BPEI) ocular microbiology laboratory and grown in pure culture. These isolates were characterized based on DNA sequence analysis of the ITS1/2 and rDNA regions. Antifungal susceptibilities were determined for each isolate using broth microdilution methods and the corresponding medical records were reviewed to determine clinical outcomes. Results Fusarium (F.) solani isolates had significantly higher voriconazole MIC90 values than F. non-solani organisms (16 and 4ug/ml, respectively). F. solani isolates also exhibited a significantly longer time to cure (65 vs 40.5 days), a worse follow up BCVA (20/118 vs 20/36), and increased need for urgent surgical management (7 vs 0 penetrating keratoplasties) when compared to F. non-solani isolates. Conclusions This is the first report to examine the correlation between ocular genotyped Fusarium species and clinical outcomes. It supports the overall worse prognosis for F. solani versus F. non-solani isolates, including higher voriconazole resistance by the former. The clinical implementation of molecular-based diagnostics and antifungal efficacy testing, may yield important prognostic and therapeutic information that could improve the management of fungal ocular infections.

    Infection after total hip (THA) and knee arthroplasty (TKA) is a serious complication which typically leads to a long lasting and intensive surgical and medicamentous treatment. The aim of this study was to identify factors that influence outcome after revision surgery caused by prosthetic infection. We retrospectively analyzed 64 patients who had revision surgery between 1989 and 2009 due to periprosthetic infection. We examined a total of 69 joints (TKA: 36%, THA: 64%), follow-up 5.1 years (0.5-21 years) after the initial surgical intervention. The mean patient age at time of surgery was 67 years old (43-79 years old). Clinical data and scores including the Western Ontario and McMaster Universities (WOMAC)-Index, the Harris Hip Score (HHS) and the Hospital for Special Surgery Score (HSS) were surveyed. There was no difference in clinical scores regarding treatment between a single and a multiple stage treatment regime. Infections with multiple microorganisms and Enterococcus spp. lead to a significantly higher number of interventions. Using a modified Tsukayama system we classified 24% as type I, 34% type II and 42% type III- infections, with no differences in clinical outcome. Overweight patients had a significantly lower HHS and WOMAC-score. Immunosuppression leads to a worse WOMAC and HSS-Score. An increased number of procedures was associated to a limping gait. Thorough surgical technique leads to good clinical results independent of infection-type and treatment philosophy. Level of Evidence III, Case Control Study.

    Although a completely normal nail would be the ideal outcome when treating onychomycosis, this is not always achievable and long treatment courses or patient expectations can impact patient adherence. We analyzed cure rates from a number of subpopulations derived from the two pivotal phase III studies with efinaconazole topical solution (10%) to provide some insights into clinically meaningful treatment outcomes and support for effective long-term management programs. Efinaconazole affords greater efficacy in milder disease, female patients, and those patients whose disease is relatively recent and confined to the great toenail, following 48 weeks' treatment. With longer treatment courses, similar results may be achieved in other subpopulations. Clinically meaningful results (a 40% improvement in the involvement of the diseased nail) were achieved with efinaconazole within six months in half the patients treated, and in over 90% of patients by study end. A greater proportion of female patients achieved clinically meaningful results at six months, although treatment success did not seem to be influenced by baseline disease severity. The majority of patients treated with efinaconazole could expect to see clinically meaningful results within six months.

    Cutaneous melanoma (CM) is the most lethal form of skin cancer. Despite the constant increase of melanoma incidence, which is in part due to incremental advances in early diagnostic modalities, mortality rates have not improved over the last decade and for advanced stages remain steadily high. While conventional prognostic biomarkers currently in use find significant utility for predicting overall general survival probabilities, they are not sensitive enough for a more personalized clinical assessment on an individual level. In recent years, the advent of genomic technologies has brought the promise of identification of germline DNA alterations that may associate with CM outcomes and hence represent novel biomarkers for clinical utilization. This review attempts to summarize the current state of knowledge of germline genetic factors studied for their impact on melanoma clinical outcomes. We also discuss ongoing problems and hurdles in validating such surrogates, and we also project future directions in discovery of more powerful germline genetic factors with clinical utility in melanoma prognostication.

    Providing safe, error-free care is the number-one priority of all health care professionals. Excellent outcomes have been associated with procedural efficiency, the implementation of evidence-based standards, and the use of tools designed to reduce the likelihood of medical error (such as computerized medication orders and bar-coded patient identification). But the impact of work relationships on clinical outcomes isn't as well documented. The current survey was designed as a follow-up to a previous VHA West Coast survey that examined the prevalence and impact of physicians' disruptive behavior on the job satisfaction and retention of nurses (see "Nurse-Physician Relationships: Impact on Nurse Satisfaction and Retention," June 2002). Based on the findings of that survey and subsequent comments on it, the follow-up survey examined the disruptive behavior of both physicians and nurses, as well as both groups' and administrators' perceptions of its effects on providers and its impact on clinical outcomes. Surveys were distributed to 50 VHA hospitals across the country, and results from more than 1,500 survey participants were evaluated. Nurses were reported to have behaved disruptively almost as frequently as physicians. Most respondents perceived disruptive behavior as having negative or worsening effects, in both nurses and physicians, on stress, frustration, concentration, communication, collaboration, information transfer, and workplace relationships. Even more disturbing was the respondents' perceptions of negative or worsening effects of disruptive behavior on adverse events, medical errors, patient safety, patient mortality, the quality of care, and patient satisfaction. These findings suggest that the consequences of disruptive behavior go far beyond nurses' job satisfaction and morale, affecting communication and collaboration among clinicians, which may well, in turn, have a negative impact on clinical outcomes. Strategies aimed at reducing the incidence and

    2001-01-01

    Background The use of telemedicine is growing, but its efficacy for achieving comparable or improved clinical outcomes has not been established in many medical specialties. The objective of this systematic review was to evaluate the efficacy of telemedicine interventions for health outcomes in two classes of application: home-based and office/hospital-based. Methods Data sources for the study included deports of studies from the MEDLINE, EMBASE, CINAHL, and HealthSTAR databases; searching of bibliographies of review and other articles; and consultation of printed resources as well as investigators in the field. We included studies that were relevant to at least one of the two classes of telemedicine and addressed the assessment of efficacy for clinical outcomes with data of reported results. We excluded studies where the service did not historically require face-to-face encounters (e.g., radiology or pathology diagnosis). All included articles were abstracted and graded for quality and direction of the evidence. Results A total of 25 articles met inclusion criteria and were assessed. The strongest evidence for the efficacy of telemedicine in clinical outcomes comes from home-based telemedicine in the areas of chronic disease management, hypertension, and AIDS. The value of home glucose monitoring in diabetes mellitus is conflicting. There is also reasonable evidence that telemedicine is comparable to face-to-face care in emergency medicine and is beneficial in surgical and neonatal intensive care units as well as patient transfer in neurosurgery. Conclusions Despite the widespread use of telemedicine in virtually all major areas of health care, evidence concerning the benefits of its use exists in only a small number of them. Further randomized controlled trials must be done to determine where its use is most effective. PMID:11737882

    The significance of collateral ligament desmitis of the tarsocrural joint is often clinically underestimated, because it is an uncommon injury with a guarded prognosis for athletic soundness. The objective of this study was to describe the clinical presentation, treatment, and outcome of 12 horses with collateral ligament desmitis, along with tarsocrural joint synovitis secondary to hemarthrosis. Criteria for inclusion in this study included clinical signs of tarsocrural joint synovitis and sonographic evidence of collateral ligament desmitis. This retrospective study evaluated horses over an 8-year period. Median follow-up after treatment was 5.5 years. Four horses in the study returned to their previous level of performance, 6 horses remained lame due to pain in the tarsus, 1 was euthanized, and 1 is in convalescence. This study highlights the importance of collateral ligament desmitis, and emphasizes the need for early, aggressive treatment to prevent the development of osteoarthritis. PMID:23115364

    To investigate the long-term clinical outcomes of biolimus-eluting stents with biodegradable polymers in real-world clinical practice. Long-term clinical outcomes of biolimus-eluting stents have not been clearly established. A total of 824 all-comer patients (971 lesions) treated with unrestricted implantation of a biolimus-eluting stent with a biodegradable polymer were prospectively enrolled. Patients were divided into complex (413 patients) versus noncomplex (411 patients) groups according to the complexity of coronary lesions. Long-term clinical outcomes for stent efficacy (target lesion revascularization) and safety (composite of cardiac death, target lesion-related myocardial infarction, and definite or probable stent thrombosis) were compared between the two groups during 5 years of follow-up. The complex group showed higher rates of decreased left ventricular ejection fraction, impaired renal function, previous history of myocardial infarction, and diabetes mellitus compared to the noncomplex group. In the overall population, the 5-year cumulative rate of target lesion revascularization was 4.8% (8.3% in the complex group vs 1.6% in the noncomplex group, P < 0.001). For stent safety, the 5-year cumulative rate for a composite of cardiac death, target lesion-related myocardial infarction, and stent thrombosis was 2.5% overall (3.9% in the complex group vs 1.1% in the noncomplex group, P = 0.010). Overall 5-year cumulative rate of stent thrombosis was 0.4% (0.5% in the complex vs 0.2% in the noncomplex group, P = 0.561) with no very late stent thrombosis (VLST). Biodegradable polymer-based biolimus-eluting stents showed favorable efficacy and safety in all-comer patients during 5 years of follow-up. © 2016, Wiley Periodicals, Inc.

    Intracranial aneurysms are extremely uncommon in the pediatric population, their characteristics are not well studied, and certain features make them unique. The authors analyzed pediatric patients with aneurysms to try to understand their clinical, radiological, and outcome profile. Sixty-three pediatric patients (≤ 18 years of age) with ages ranging from 4 to 18 years and features (clinical and radiological) suggestive of aneurysm presented to, and were treated at, the authors' center in the past 20 years (1991-2011). Included in the present study were only those patients who underwent surgical intervention, and thus data for 57 patients were analyzed. Seventy-three aneurysms in 57 patients were surgically treated. There was a slight female predominance (M/F 1:1.2), and the mean age among all patients was 12.69 ± 3.75 years. Fifty patients (87.72%) presented with subarachnoid hemorrhage, 4 (7.02%) with mass effect, and 3 (5.26%) with seizure. On presentation the majority of patients (45 [78.95%]) had a good clinical grade. Eleven patients had multiple aneurysms. The internal carotid artery (ICA) bifurcation was the most common aneurysm site (18 cases [24.66%]), followed by the middle cerebral artery (MCA) bifurcation (11 cases [15.07%]). At a mean follow-up of 18.58 ± 10.71 months (range 1.5-44 months), 44 patients (77.19%) had a favorable outcome, and 5 patients had died. Pediatric patients with intracranial aneurysms most commonly presented with subarachnoid hemorrhage, and there was a slight female predominance. The ICA bifurcation followed by the MCA bifurcation was the most common aneurysm site. The incidence of posterior circulation and giant aneurysms is higher in pediatric patients than in the adult population. Children tend to present with better clinical grades and have better overall survival results and good functional outcomes.

    Background Development of new therapies for Alzheimer's disease (AD) is increasingly focused on more mildly affected populations, and requires new assessment and outcome strategies. Patients in early stages of AD have mild cognitive decline and no, or limited, functional impairment. To respond to these assessment challenges, we developed a measurement approach based on established scale items that exhibited change in previous amnestic Mild Cognitive Impairment (aMCI) trials. Methods Partial least squares regression with a longitudinal clinical decline model identified items from commonly used clinical scales with the highest combined sensitivity to change over time in aMCI and weighted these items according to their relative contribution to detecting clinical progression in patients’ early stages of AD. The resultant AD Composite Score (ADCOMS) was assessed for its ability to detect treatment effect in aMCI/prodromal AD (pAD) clinical trial populations. Results ADCOMS consists of 4 Alzheimer's Disease Assessment Scale–cognitive subscale items, 2 Mini-Mental State Examination items, and all 6 Clinical Dementia Rating—Sum of Boxes items. ADCOMS demonstrated improved sensitivity to clinical decline over individual scales in pAD, aMCI and in mild AD dementia. ADCOMS also detected treatment effects associated with the use of cholinesterase inhibitors in these populations. Improved sensitivity predicts smaller sample size requirements when ADCOMS is used in early AD trials. Conclusions ADCOMS is proposed as new standard outcome for pAD and mild AD dementia trials, and is progressing in a CAMD-sponsored qualification process for use in registration trials of pAD.

    Conventional algorithms for modeling clinical events focus on characterizing the differences between patients with varying outcomes in historical data sets used for the model derivation. For many clinical conditions with low prevalence and where small data sets are available, this approach to developing models is challenging due to the limited number of positive (that is, event) examples available for model training. Here, we investigate how the approach of developing clinical models might be improved across three distinct patient populations (patients with acute coronary syndrome enrolled in the DISPERSE2-TIMI33 and MERLIN-TIMI36 trials, patients undergoing inpatient surgery in the National Surgical Quality Improvement Program registry, and patients undergoing percutaneous coronary intervention in the Blue Cross Blue Shield of Michigan Cardiovascular Consortium registry). For each of these cases, we supplement an incomplete characterization of patient outcomes in the derivation data set (uncensored view of the data) with an additional characterization of the extent to which patients differ from the statistical support of their clinical characteristics (censored view of the data). Our approach exploits the same training data within the derivation cohort in multiple ways to improve the accuracy of prediction. We position this approach within the context of traditional supervised (2-class) and unsupervised (1-class) learning methods and present a 1.5-class approach for clinical decision-making. We describe a 1.5-class support vector machine (SVM) classification algorithm that implements this approach, and report on its performance relative to logistic regression and 2-class SVM classification with cost-sensitive weighting and oversampling. The 1.5-class SVM algorithm improved prediction accuracy relative to other approaches and may have value in predicting clinical events both at the bedside and for risk-adjusted quality of care assessment.

    To guide risk management in uveitis. Retrospective review of malpractice verdicts, rulings, and settlements. The WestLaw® database was reviewed for lawsuits related to uveitis in the United States from 1930-2014. Twenty-five cases met inclusion criteria, and 48% of these were infectious. Overall, 64% of outcomes favored the defendant ophthalmologist. The most common diagnoses were viral retinitis (28%), iritis (12%), syphilis (8%), and toxoplasmosis (8%). Seven suits (28%) were resolved by settlement, with mean adjusted indemnities of $724,302 (median, $409,390; range, $127,837-2,021,887). Two cases (8%) resulted in plaintiff verdict, with adjusted awards of $1,399,800 and $630,799. Despite being a rare diagnosis, viral retinitis (especially acute retinal necrosis) is the most common clinical entity associated with litigation in uveitis and should be considered early. Educating patients about potential adverse events, early testing for syphilis, and maintaining a positive relationship may also minimize risk.

    Study design: Retrospective diagnostic feasibility study and clinical review. Objectives: To evaluate the feasibility of making an initial atlanto-occipital dissociation (AOD) diagnosis from four radiological measurements of the craniocervical relationship on lateral cervical spine x-rays and to assess the AOD patients' clinical outcomes relative to their magnetic resonance imaging (MRI) findings. Methods: The Powers ratio, Wackenheim line, basion-dens distance (BDD), and the C1/2:C2/3 interspinous ratio were measured in 58 pediatric controls and ten MRI-confirmed patients with AOD. The ability to identify the required anatomical landmarks and make the measurements was noted and sensitivity and specificity calculated. The correspondence between the clinical presentation and outcomes for patients with AOD and their MRI features was investigated. Results: Clear landmarks for measuring interspinous ratio and Wackenheim line were confirmed by all x-rays. The BDD was measureable in 90% and the Powers ratio could be calculated in only possible in 59%. The interspinous ratio and BDD offered high sensitivities and specificity. Although the Wackenheim line was consistantly measured, it conferred a low sensitivity but reasonable specificity. The Powers ratio offered high specificity with low sensitivity. On MRI, all patients with AOD had apical ligament disruption, with a high rate of interspinous ligamentous injury (8/9); prevertebral swelling (7/9); retroclival hematoma (6/9); and tectorial membrane injury (4/9). The only MRI feature associated with poor outcome was that of altered cord signal. Both patients who died had cord signal changes on T1- and T2-weighted images. The third patient with cord signal change was limited to T2 changes with a normal T1. He had a C5-L3 sensory deficit that resolved. The degree of tectorial membrane injury did not appear to influence outcome. Conclusions: The BDD and interspinous ratio offer the best measures for initial x

    Spiral family implants (SFIs) are a new type of implant fixture with a conical internal helix and a variable thread design. The aim of this retrospective study was to evaluate the clinical outcomes of a series of SFIs. A total of 234 SFIs were placed in 86 patients (55 females and 31 males, median age 53 years) during the period between May 2004 and November 2007. The mean follow-up was 13 months. Several host, surgery, and implant-related factors were investigated, and the Kaplan Meier algorithm and the Cox regression were used to detect variables associated with the clinical outcome. Only nine out of 234 implants were lost (i.e., survival rate (SVR) of 96.2%) and no differences were detected among the studied variables. SFIs have a high SVR similar to those reported in previous studies on different implant types. SFIs demonstrated a very high primary stability which offers the potential for use of a specific implant device for immediate loading. However, additional studies are necessary to verify their outcome on the medium/long period.

    To examine the etiological factors, clinical features, treatment modalities and outcome of acute respiratory failure in children. This hospital-based prospective observational study was conducted over 15 months. Fifty children with acute respiratory failure, diagnosed by serial arterial blood gas analysis, were consecutively enrolled. Ventilation therapy was initiated when the FiO2 requirement went above 0.6. Pulmonary diseases accounted for majority (68%) of cases, followed by nervous system (12%); and cardiovascular and skeletal muscle system diseases (10%, each). Bronchopneumonia was the commonest cause of acute respiratory failure (11 cases). The majority of cases were in the age group 1 month to < 1 year (26 cases). The commonest signs were altered depth and pattern of respiration (100%), chest wall retractions (88%), flaring of alae nasae (88%), tachypnea (84%), tachycardia (82%), and irritability (64%). Cyanosis was noticed in only 26 (52%) cases. Thirty-six (72%) children required ventilation therapy. The overall mortality was 58%. The mortality was high (55.9% to 66.7%), irrespective of the primary system involved. Significantly higher mortality was associated with co-existent malnutrition (p<0.001), Type I failure (p=0.039) and ventilation therapy (p<0.0001). Acute respiratory failure has varied etiology and clinical manifestations, and a high mortality. Its outcome is independent of age of the child and the primary system involved. Malnutrition and Type I failure are factors associated with a poor outcome.

    Despite advances in cardiopulmonary resuscitation (CPR), survival remains low after out-of-hospital cardiac arrest (OOHCA). Acute coronary ischemia is the predominating precipitant, and prompt delivery of patients to dedicated facilities may improve outcomes. Since 2011, all patients experiencing OOHCA in London, where a cardiac etiology is suspected, are systematically brought to heart attack centers (HACs). We determined the predictors for survival and favorable functional outcomes in this setting. We analyzed 174 consecutive patients experiencing OOHCA from 2011 to 2013 brought to Harefield Hospital-a designated HAC in London. We analyzed (1) all-cause mortality and (2) functional status using a modified Rankin scale (mRS 0 to 6, where mRS0-3(+) = favorable functional status). The overall survival rates were 66.7% (30 days) and 62.1% (1 year); and 54.5% had mRS0-3(+) at discharge. Patients with mRS0-3(+) had reduced mortality compared to mRS0-3(-): 30 days (1.2% vs 72.2%, p <0.001) and 1 year (5.3% vs 77.2%, p <0.001). Multivariate analyses identified lower patient comorbidity, absence of cardiogenic shock, bystander CPR, ventricular tachycardia/ventricullar fibrillation as initial rhythm, shorter duration of resuscitation, prehospital advanced airway, absence of adrenaline and inotrope use, and intra-aortic balloon pump use as predictors of mRS0-3(+). Consistent predictors of increased mortality were the presence of cardiogenic shock, advanced airway use, increased duration of resuscitation, and absence of therapeutic hypothermia. A streamlined delivery of patients experiencing OOHCA to dedicated facilities is associated with improved functional status and survival. Our study supports the standardization of care for such patients with the widespread adoption of HACs. Copyright © 2015 Elsevier Inc. All rights reserved.

    Clinical trial registries are in widespread use to promote transparency around trials and their results. To describe characteristics of drug trials listed in ClinicalTrials.gov and examine whether the funding source of these trials is associated with favorable published outcomes. An observational study of safety and efficacy trials for anticholesteremics, antidepressants, antipsychotics, proton-pump inhibitors, and vasodilators conducted between 2000 and 2006. ClinicalTrials.gov, a Web-based registry of clinical trials launched in 1999. Publications resulting from the trials for the 5 drug categories of interest were identified, and data were abstracted on the trial record and publication, including timing of registration, elements of the study design, funding source, publication date, and study outcomes. Assessments were based on the primary funding categories of industry, government agencies, and nonprofit or nonfederal organizations. Among 546 drug trials, 346 (63%) were primarily funded by industry, 74 (14%) by government sources, and 126 (23%) by nonprofit or nonfederal organizations. Trials funded by industry were more likely to be phase 3 or 4 trials (88.7%; P < 0.001 across groups), to use an active comparator in controlled trials (36.8%; P = 0.010 across groups), to be multicenter (89.0%; P < 0.001 across groups), and to enroll more participants (median sample size, 306 participants; P < 0.001 across groups). Overall, 362 (66.3%) trials had published results. Industry-funded trials reported positive outcomes in 85.4% of publications, compared with 50.0% for government-funded trials and 71.9% for nonprofit or nonfederal organization-funded trials (P < 0.001). Trials funded by nonprofit or nonfederal sources with industry contributions were also more likely to report positive outcomes than those without industry funding (85.0% vs. 61.2%; P = 0.013). Rates of trial publication within 24 months of study completion ranged from 32.4% among industry-funded trials

    Introduction Trial design for SMA depends on meaningful rating scales to assess outcomes. In this study Rasch methodology was applied to 9 motor scales in spinal muscular atrophy (SMA). Methods Data from all 3 SMA types were provided by research groups for 9 commonly used scales. Rasch methodology assessed the ordering of response option thresholds, tests of fit, spread of item locations, residual correlations, and person separation index. Results Each scale had good reliability. However, several issues impacting scale validity were identified, including the extent that items defined clinically meaningful constructs and how well each scale measured performance across the SMA spectrum. Conclusions The sensitivity and potential utility of each SMA scale as outcome measures for trials could be improved by establishing clear definitions of what is measured, reconsidering items that misfit and items whose response categories have reversed thresholds, and adding new items at the extremes of scale ranges.

    Purpose. Primary hemorrhage in the ventricular system without a recognizable parenchymal component is very rare. This single-center retrospective study aimed to further characterize the clinical characteristics and early outcome of this stroke subtype. Methods. All patients with primary intraventricular hemorrhage included in a prospective hospital-based stroke registry over a 19-year period were assessed. A standardized protocol with 161 items, including demographics, risk factors, clinical data, neuroimaging findings, and outcome, was used for data collection. A comparison was made between the groups of primary intraventricular hemorrhage and subcortical intracerebral hemorrhage. Predictors of primary intraventricular hemorrhage were identified by logistic regression analysis. Results. There were 12 patients with primary intraventricular hemorrhage (0.31% of all cases of stroke included in the database) and 133 in the cohort of subcortical hemorrhage. Very old age (≥85 years) (odds ratio (OR) 9.89), atrial fibrillation (OR 8.92), headache (OR 6.89), and altered consciousness (OR 4.36) were independent predictors of intraventricular hemorrhage. The overall in-hospital mortality rate was 41.7% (5/12) but increased to 60% (3/5) in patients aged 85 years or older. Conclusion. Although primary intraventricular hemorrhage is uncommon, it is a severe clinical condition with a high early mortality. The prognosis is particularly poor in very old patients. PMID:22966468

    Tuberculous spondylodiscitis (TS) is a rare but serious clinical condition which may lead to severe deformity and early or late neurological complications. To discuss certain aspects of the approach to TSs, focusing upon epidemiology, diagnosis, and treatment outcome. For the purpose of this review, a literature search was performed using the Pubmed database through to 19th October 2011 to identify studies published in the last 20 years, concerned in epidemiological, clinical, diagnostic, and therapeutical aspects of TS in adults. Only studies drafted in English language and reporting case series of more than 20 patients have been included. TS has been reported to accounts for 1-5% of all TB cases, and for about 50% of the cases of articulo-skeletal TB infections. Despite the actual availability of more effective diagnostic tools, early recognition of TS remains difficult and a high index of suspicion is needed due to the chronic nature of the disease and its insidious and variable clinical presentation. A prompt diagnosis is required to improve long term outcome, and a microbiological confirmation is recommended to enable appropriate choice of anti-mycobacterial agents. Surgery has an important role in alleviating pain, correcting deformities and neurological impairment, and restoring function. Further studies are required to assess the appropriate duration of anti-microbial treatment, also in regarding of a combined surgical approach.

    Objectives To investigate the clinical characteristics, adverse drug reactions, and outcomes of the oldest old patients (aged ≥80 years) with tuberculosis (TB) treated with rifampicin, isoniazid, and pyrazinamide (RIP)-containing regimens. Design A retrospective chart review study. Setting A 1,200-bed tertiary teaching hospital in southwest Taiwan. Participants We conducted a retrospective observational study between January 1, 2005 and December 31, 2011. Seven hundred adult patients (aged ≥18 years) with TB treated with RIP-containing anti-TB regimens were reviewed, including 161 oldest old patients. Outcome measures Clinical outcomes included clinical responsiveness and microbiological eradication. Adverse outcomes included drug-induced hepatitis, and other symptoms included gastrointestinal upset (eg, abdominal pain, vomiting, diarrhea, or dyspepsia), skin rash, joint pain, and hyperuricemia. Results Compared with the non-oldest old adult patients, the oldest old patients more frequently had hepatitis (P=0.014), gastrointestinal upset (P=0.029), and unfavorable outcomes (P<0.001). In a multivariate analysis, hepatitis during treatment (adjusted odds ratio: 3.482, 95% confidence interval: 1.537–7.885; P<0.003) and oldest old age (adjusted odds ratio: 5.161, 95% confidence interval: 2.294–11.613; P<0.010) were independent risk factors for unfavorable outcomes. In the oldest old patients with hepatitis, rifampicin use was more common in the favorable outcome group than in the unfavorable outcome group (100% vs 37.5%; P=0.001). Conclusion The oldest old age and hepatitis during RIP treatment were associated with unfavorable outcomes. For the oldest old patients with TB having hepatitis during treatment, rifampicin rechallenge and use might benefit the treatment outcome. PMID:27042029

    It has been suggested that one way to increase speech pathologists' confidence in working with people who stutter is to provide them with relevant and stimulating clinical experiences during their professional preparation. This paper describes a treatment programme for adults who stutter that is conducted by speech pathology students, under supervision, in an Australian university setting. The aim of the research presented here was to establish speech outcomes for this programme, and to determine whether the programme meets benchmarks set by reports of similar programmes, in addition to providing mentorship for student clinicians. Participants were 78 adults who were treated in one of five consecutive treatment programmes during a 3-year period. The treatment was a traditional intensive speech restructuring treatment known as Smooth Speech, conducted over a 5-day period. Speech assessments were conducted 1 week and 1 day before the start of the treatment programme. Post-treatment assessments were conducted immediately following the intensive component of the programme, and 3 months, 12 months and 3.5-5 years post-treatment. The student clinic treatment model in this report produced objective speech data for more subjects in one outcome study than has ever been reported before. Data for 87% (68/78) of participants were available at 3.5-5-year follow-up. Results showed that outcomes for stuttering, speech naturalness, and client self-reports were all comparable with existing reports of similar programmes. The present results were attained with a student/supervisor ratio of around 8:1. We conclude that a clinician-supervised student clinic has the potential to supply services for those with chronic stuttering, as well as providing effective clinical education for student clinicians during their professional preparation. The student clinic treatment model produced varied, objective speech data for more subjects than has ever been reported before in one study. The

    Abstract This prospective cohort study aimed to elucidate the clinical outcome and its related factors of chronic hepatitis C in a hepatitis B-dominant Asian region. From January 2007 to October 2012, 382 patients with chronic hepatitis C without liver cirrhosis were prospectively enrolled at 6 university hospitals, and regularly followed until Apr 2014 to identify the development of liver cirrhosis, decompensated cirrhosis, hepatocellular carcinoma (HCC), and overall survival. During the median follow-up of 39.0 months (range 18.0–81.0 months), liver cirrhosis, hepatic decompensation, and HCC developed in 42 patients (11.0%), 4 patients (1.0%), and 12 patients (3.1%), respectively. The cumulative probability of development of cirrhosis at 3 years and at 5 years was 9.6% and 16.7%, respectively. That of HCC at 3 and 5 years was 1.6% and 4.5%, respectively. The 3-year and 5-year overall survival rate was 99.7% and 96.0%, respectively. Pegylated interferon-based antiviral therapy was undertaken in 237 patients (62.0%) with a sustained virologic response (SVR) rate of 74.3%. The factors related to the overall clinical outcomes were age ≥55 years (HR 2.924, P = 0.016), platelet counts <150  × 109/L (HR 3.195, P = 0.007), and the achievement of SVR (HR 0.254, P = 0.002). The clinical outcomes of this Korean chronic hepatitis C cohort were modest with minimal mortality, but significant disease progression occurred in the patients with old age, low platelet, and non-SVR after interferon-based antiviral treatment or no treatment, suggesting priority for direct acting antiviral therapy.

    Hip abductor tendon (HAT) tearing is commonly implicated in greater trochanteric pain syndrome. Surgical studies are often reported in small cohorts and with limited information on functional improvement. This study reports the clinical and functional outcomes after HAT repair. 112 patients with symptomatic HAT tears, diagnosed via magnetic resonance imaging, underwent open bursectomy, V-Y lengthening of the iliotibial band, debridement of the diseased tendon, decortication of the trochanteric foot-plate and reattachment of the tendon with suture anchors, augmented with a LARS ligament through a trans-osseous tunnel. Patients were evaluated pre-surgery and at 3, 6 and 12 months post-surgery using the Harris (HHS) and Oxford (OHS) Hip Scores, SF-12, hip range of motion, 6-minute walk and 30-second single leg stance tests. Maximal isometric hip abduction strength (HAS) was assessed and limb symmetry indices (LSIs) were calculated between the operated and non-operated limbs. Patient satisfaction and perceived global rating of change (GRC) was evaluated. Analysis of variance evaluated improvement over time. There was a significant improvement (p<0.05) in all clinical and functional measures. HAS significantly improved over time (p<0.002) and all LSIs were >85% at 12 months. At 12 months, a mean GRC score of 3.5 (range -1 to 5) was reported, while 96% of patients were satisfied with their surgical outcome. There was a 2.7% (n = 3) failure rate at 12 months. HAT reconstruction, augmented with a synthetic ligament, demonstrated significantly improved clinical and functional outcomes, high levels of patient satisfaction and a low failure rate to 12 months post-surgery.

    The purpose of our study was to examine the effectiveness of general health-promotion teaching for patients in the waiting room of a clinic, using focused videotape instruction. An experimental design was used. Subjects were patients (N = 215) in the waiting rooms of clinics in a university medical center in the Midwest. Patients were randomly assigned to two groups: focused videotape instruction in the clinic (n = 106) and control (no instruction in the clinic waiting area) (n = 109). The outcome measures included patient learning about a health education topic and patient satisfaction with overall care, explanations by the provider, and education received during the clinic visit. There was a significant gain in knowledge for patients who viewed the videotape in the waiting room (t = 5.43, df = 213, p < .0001), and they were more satisfied with their education compared with the control group (t = 4.73, df = 213, p < .0001). This study supports focused video instruction as an effective and efficient teaching intervention for disseminating health information in the waiting area.

    The purpose of this study was to compare traditional methods of instruction to the use of audiovisual patient safety vignettes in terms of their impact on student registered nurse anesthetists' recall and subsequent clinical performance. These vignettes used simulated, crisis-oriented anesthetic events known to be associated with catastrophic patient outcomes. Using a randomized controlled crossover trial, 24 student registered nurse anesthetists encountered either a malfunctioning suction device vignette or a stuck expiratory unidirectional valve vignette. Recall and clinical performances were measured after exposure to a lecture and written case studies or to lecture and patient safety vignettes. Of the 24 students, 23 were able to recognize the malfunctioning components and take corrective action. In this research study, memory and clinical performance were significantly affected when the anesthesia provider incorporated the correct anesthesia apparatus checkout process and crisis management skills into practice. This research demonstrated that under the conditions of this study, teaching methods had an impact on some areas of clinical performance. In this study, crisis-oriented, anesthesia patient safety vignettes had the potential to affect recall and clinical performance in a simulated environment.

    This study analyzed the impact of a pharmacist-managed diabetes clinic on clinical outcomes compared to usual care received from primary care providers (PCPs). This comparison may more definitively demonstrate the value of pharmacist management of chronic disease states. Retrospective observational cohort study conducted in patients referred to a pharmacist-managed pharmacotherapy (PT) clinic from July 2009 to October 2014. For the primary outcome, the absolute change in A1c during the usual care phase was +1.53% (95% confidence interval [CI]: 1.10-1.96, P < .0001) versus an absolute change of -1.63% (95% CI: -1.28 to -1.97, P < .0001) in the intervention phase. For secondary outcomes, diabetes-related hospitalizations (10 vs 6, P = .104) and emergency room (ER) visits (27 vs 8, P = .049) decreased in the intervention phase compared to the usual care phase. The rate of diabetes-related interventions made per patient per year in the usual care phase was 2.7 versus 11.1 in the intervention phase ( P < .0001). Patients referred to the PT clinic had worsening blood glucose control prior to referral, and their control improved after referral to the clinic. Furthermore, there was an improvement in all diabetes-related outcomes in the intervention phase compared to the usual care phase.

    Malnutrition is a common problem in oncological diseases, influencing treatment outcomes, treatment complications, quality of life and survival. The potential role of malnutrition has not yet been studied systematically in neuroendocrine neoplasms (NEN), which, due to their growing prevalence and additional therapeutic options, provide an increasing clinical challenge to diagnosis and management. The aim of this cross-sectional observational study, which included a long-term follow-up, was therefore to define the prevalence of malnutrition in 203 patients with NEN using various methodological approaches, and to analyse the short- and long-term outcome of malnourished patients. A detailed subgroup analysis was also performed to define risk factors for poorer outcome. When applying malnutrition screening scores, 21-25% of the NEN patients were at risk of or demonstrated manifest malnutrition. This was confirmed by anthropometric measurements, by determination of serum surrogate parameters such as albumin as well as by bioelectrical impedance analysis (BIA), particularly phase angle α. The length of hospital stay was significantly longer in malnourished NEN patients, while long-term overall survival was highly significantly reduced. Patients with high-grade (G3) neuroendocrine carcinomas, progressive disease and undergoing chemotherapy were at particular risk of malnutrition associated with a poorer outcome. Multivariate analysis confirmed the important and highly significant role of malnutrition as an independent prognostic factor for NEN besides proliferative capacity (G3 NEC). Malnutrition is therefore an underrecognized problem in NEN patients which should systematically be diagnosed by widely available standard methods such as Nutritional Risk Screening (NRS), serum albumin assessment and BIA, and treated to improve both short- and long-term outcomes. © 2015 S.

    An outcome assessment, the patient assessment used in an endpoint, is the measuring instrument that provides a rating or score (categorical or continuous) that is intended to represent some aspect of the patient's health status. Outcome assessments are used to define efficacy endpoints when developing a therapy for a disease or condition. Most efficacy endpoints are based on specified clinical assessments of patients. When clinical assessments are used as clinical trial outcomes, they are called clinical outcome assessments (COAs). COAs include any assessment that may be influenced by human choices, judgment, or motivation. COAs must be well-defined and possess adequate measurement properties to demonstrate (directly or indirectly) the benefits of a treatment. In contrast, a biomarker assessment is one that is subject to little, if any, patient motivational or rater judgmental influence. This is the first of two reports by the ISPOR Clinical Outcomes Assessment - Emerging Good Practices for Outcomes Research Task Force. This report provides foundational definitions important for an understanding of COA measurement principles. The foundation provided in this report includes what it means to demonstrate a beneficial effect, how assessments of patients relate to the objective of showing a treatment's benefit, and how these assessments are used in clinical trial endpoints. In addition, this report describes intrinsic attributes of patient assessments and clinical trial factors that can affect the properties of the measurements. These factors should be considered when developing or refining assessments. These considerations will aid investigators designing trials in their choice of using an existing assessment or developing a new outcome assessment. Although the focus of this report is on the development of a new COA to define endpoints in a clinical trial, these principles may be applied more generally. A critical element in appraising or developing a COA is to

    The purpose of the present study was to investigate two years clinical outcome of patients having myofacial pain dysfunction syndrome (MPDS). A total of 50 patients (male: 15, Female: 35, age: raged from 20 to 65 years) were included for this study. Clinical diagnosis for the assessment of anxiety and depression of each patient was performed by Hospital anxiety and depression (HAD) scale. Patients were then received either one of the following treatments: Occlusion correction only (n=14), Muscle Relaxant + anti-depressant drug (n=26), Physiotherapy + antidepressant drug + muscle relaxant (n=6) and Appliance + muscle relaxant (n= 4). Following two years observation, it was revealed that the treatment was apparently successful in 95% case; only 5% case was not successful due to their irregular visit. It can be concluded that MPDS is not primarily related to occlusal factors and a complex psycho physiological mechanism is involved in this type of pain problems.

    Little is known about the clinical characteristics and surgical outcomes of valgus extension overload syndrome (VEOS) in adolescent athletes. We evaluated posteromedial compartment pathology, including combined lesions, and reported the surgical outcomes in adolescent baseball players. We retrospectively reviewed the medical records of 13 male adolescent baseball players (mean age, 15.4 years) who underwent arthroscopic olecranon tip resection (n = 9) or staged operations (arthroscopic olecranon tip resection, followed by medial collateral ligament reconstruction 2 weeks later; n = 4). The shape of the tip fragment was used to classify the olecranon into 2 types: type 1, dot-like fragment (n = 3); type 2, triangular-shape fragment (n = 10). Four outcome measures were analyzed: range of motion, visual analog scale (VAS) pain score, rate of return to play, and Conway scale score. At a mean follow-up of 3.3 years (range, 2-6 years), the mean VAS pain score decreased from 4.1 preoperatively to 1.1 postoperatively (P < .05). Preoperative mean extension and supination were 4.2° and 70.0°, which improved to 1° (P < .05) and 76.2° (P < .05), respectively. The overall rate of return to play was 85% (11 of 13). On the Conway scale, 8 of 13 patients (62%) were classified as excellent. Patients who underwent isolated arthroscopic surgery reported less pain postoperatively and achieved a higher grade on the Conway scale than patients who underwent staged operations. Arthroscopic resection of olecranon tip yielded favorable outcomes at a minimum of 2 years of follow-up. Patients with concomitant ulnar collateral ligament insufficiency had less optimal outcomes than those with isolated posteromedial impingement.

    In light of recent evidence suggesting enhancement of daptomycin activity against vancomycin-resistant Enterococcus (VRE) by ampicillin and other β-lactam antibiotics, we evaluated the safety profile and clinical efficacy of daptomycin with and without concomitant β-lactam antimicrobials in the treatment of VRE (faecium or faecalis) bacteremia from multiple centers across the United States. Data were collected retrospectively as part of a larger multicenter registry (The Cubicin Outcomes Registry and Experience). Efficacy and clinical outcomes in patients with VRE bacteremia who received at least 3 days of daptomycin with or without concomitant β-lactams were analyzed. Although all the cases involved daptomycin-susceptible VRE, additional analysis was performed to examine whether the adjunctive β-lactam would play a more pivotal role in cases where the daptomycin MIC was in the upper limit of the susceptibility range, indicating that daptomycin monotherapy efficacy may be relatively compromised compared with cases with lower daptomycin MICs. Two hundred sixty-two patients from 33 hospitals were evaluated. Most patients had at least one significant comorbidity, such as solid-organ or bone marrow transplantation (16%), neutropenia (36%), dialysis dependency (20%), or critical illness (36%) requiring care in an intensive care unit. Overall treatment success was 86% (n = 225/262), and treatment success for patients taking concomitant β-lactams was 86% (n = 105/122). Logistic regression identified treatment failure to be associated with sepsis (odds ratio = 3.42; P = 0.009) and an elevated daptomycin MIC (3-4 µg/mL) (odds ratio = 3.23, P = 0.013). No significant increase in clinical failure was seen among patients with elevated daptomycin MIC who received concomitant β-lactam therapy (clinical success, 88% vs 79% for MIC ≤2 vs 3-4 µg/mL, respectively; P = 0.417). Of 262 patients, 33 (13%) experienced ≥1 adverse event possibly related to daptomycin (increased

The aim of this study was to identify factors that influence outcome after revision surgery caused by prosthetic infection. Methods: We retrospectively analyzed 64 patients who had revision surgery between 1989 and 2009 due to periprosthetic infection. We examined a total of 69 joints (TKA: 36%, THA: 64%), follow-up 5.1 years (0.5-21 years) after the initial surgical intervention. The mean patient age at time of surgery was 67 years old (43-79 years old). Clinical data and scores including the Western Ontario and McMaster Universities (WOMAC)-Index, the Harris Hip Score (HHS) and the Hospital for Special Surgery Score (HSS) were surveyed. Results: There was no difference in clinical scores regarding treatment between a single and a multiple stage treatment regime. Infections with multiple microorganisms and Enterococcus spp. lead to a significantly higher number of interventions. Using a modified Tsukayama system we classified 24% as type I, 34% type II and 42% type III- infections, with no differences in clinical outcome. Overweight patients had a significantly lower HHS and WOMAC-score. Immunosuppression leads to a worse WOMAC and HSS-Score. An increased number of procedures was associated to a limping gait. Conclusion: Thorough surgical technique leads to good clinical results independent of infection-type and treatment philosophy. Level of Evidence III, Case Control Study. PMID:26997914

    non-buffered agent (P < .01). Mean score for pain on injection for nerve block (n = 46 scores) was 3.3 (standard deviation, 0.9). Seventy-eight percent of subjects reported lower or the same pain scores with the buffered drug; 61% of subjects reported a shorter time to lower lip numbness with the buffered drug. Buffering 2% lidocaine with epinephrine can produce clinical outcomes favorable for subjects and clinicians without clinically detrimental peak blood lidocaine levels.

    The aim of the present study was to comprehensively evaluate the clinical features and long-term outcomes of congenital aural stenosis (CAS). This study presents a retrospective review of patients who underwent meatoplasty for CAS at a tertiary referral hospital from 2008 to 2015. A total of 246 meatoplasty procedures were performed on 232 patients in the present study. We performed multivariate regression analysis. Except in the age < 6 years group, no significant difference was observed among different age groups for cholesteatoma formation, p > 0.05. Except for the stenosis of the external auditory canal (EAC) (>4 mm) group, the other stenosis of EAC groups were not associated with cholesteatoma formation, p > 0.05. Postoperative air-bone gaps (ABG) less than 30 dB occurred in 77.3% (99/128) of the patients, and the Jahrsdoerfer score was associated with postoperative ABG, p < 0.001. The complication rate of CAS was 13.8% (20/144), and males showed a higher risk for postoperative complications (OR, 6.563; 95% CI, 1.268–33.966, p = 0.025). These results indicate that meatoplasty was an effective surgical intervention for CAS, showing a stable hearing outcome with prolonged follow-up. There was no significant difference between the cholesteatoma and no cholesteatoma groups for hearing outcomes, p > 0.05. PMID:27257165

    This review of controlled outcome research on Autogenic Training complements the literature by pooling narrative and quantitative approaches, by including only studies with experimental controls, by integrating the English and German literature, and by adding research findings published since the last review. Whereas previous reviews have already reported positive effects of Autogenic Training for migraine, insomnia, and test anxiety, additional supportive findings for angina pectoris, asthma, childbirth, eczema, hypertension, infertility, Raynaud's disease, and recovery from myocardial infarction are discussed here. The impact of protocol variations on outcome is described, and the specificity of Autogenic Training relative to other stress management techniques is highlighted. Quantitative findings suggested that Autogenic Training was associated with medium-sized pre- to posttreatment effects ranging from d = .43 for biological indices of change to d = .58 for psychological and behavioral indices thus matching effect sizes for other biobehavioral treatment techniques like biofeedback and muscular relaxation. Length of treatment did not affect clinical outcome. The discussion emphasizes how narrative and quantitative strategies complement one another.

    Abstract After initial evaluation in the Emergency Department (ED), many patients complaining of abdominal pain are classified as suffering from nonsurgical abdominal pain (NSAP). Clinical characteristics and risk factors for worse prognosis were not published elsewhere. Characterizing the clinical profile of patients hospitalized due to NSAP and identifying predictor variables for worse clinical outcomes. We made a retrospective cohort analysis of patients hospitalized due to NSAP compared to matched control patients (for age, gender, and Charlson comorbidity index) hospitalized due to other, nonsurgical reasons in a ratio of 1 to 10. We further performed in-group analysis of patients admitted due to NSAP in order to appreciate variables (clinical and laboratory parameters) potentially associated with worse clinical outcomes. Overall 23,584 patients were included, of which 2144 were admitted due to NSAP and 21,440 were matched controls. Patients admitted due to NSAP had overall better clinical outcomes: they had lower rates of in-hospital and 30-days mortality (2.8% vs 5.5% and 7.9% vs 10.4% respectively, P < 0.001 for both comparisons). They also had a significantly shorter length of hospital stay (3.9 vs 6.2 days, P < 0.001). Rates of re-hospitalization within 30-days were not significantly different between study groups. Among patients hospitalized due to NSAP, we found that vomiting or hyponatremia at presentation or during hospital stay were associated with worse clinical outcomes. Compared to patients hospitalized due to other, nonsurgical reasons, the overall prognosis of patients admitted due to NSAP is favorable. The combination of NSAP with vomiting and hyponatremia is associated with worse clinical outcomes. PMID:27057886

    Although there are multiple reports on surgical outcomes of type 2 superior labral anterior posterior (SLAP) repairs, a literature review noted a paucity of data on clinical and radiological outcomes in elite overhead athletes. To determine midterm clinical outcomes of type 2 SLAP repairs in elite overhead athletes and whether labral integrity provides consistent return to play. Case series; Level of evidence, 4. Medical records were retrospectively reviewed of 24 elite overhead athletes who underwent arthroscopic type 2 SLAP repairs. There were 18 men and 6 women, and their mean age was 22.7 years (range, 19-30 years); the majority of them (16/24) were baseball players. Four outcome measures were used: visual analog scale (VAS) for pain and satisfaction, American Shoulder and Elbow Surgeons (ASES) score, subjective feeling of recovery, and return to play. Multidetector computed tomographic arthrography was performed to evaluate labral integrity after surgery. At a mean follow-up of 45.8 months (range, 24-68 months), overall pain and function improved significantly. The VAS for pain was 5.7 preoperatively and 2.0 postoperatively (P < .01), and VAS for satisfaction was 8.6. The ASES score was 55.8 preoperatively and 87.1 postoperatively (P < .01). The overall mean value of subjective feeling of recovery was approximately 76%. Twelve of 24 athletes (50%) returned to play after the operation. Although there was a trend toward higher return rate in the other overhead athletes (75%) compared with the baseball players (38%), this trend did not reach statistical significance (P = .097). Labral retear with clinical significance was noted in 2 athletes who failed to return to play. Osteolysis was observed in 2 athletes, 1 of whom had a retear. A statistical relation between the integrity of the repair and return to play was not found (P > .05). Arthroscopic SLAP repairs show favorable clinical and radiological outcomes; however, the study findings raise a concern that

  12. A clinically meaningful theory of outcome measures in rehabilitation medicine.

    Comparative effectiveness research in rehabilitation medicine requires the development and validation of clinically meaningful and scientifically rigorous measurements of patient states and theories that explain and predict outcomes of intervention. Patient traits are latent (unobservable) variables that can be measured only by inference from observations of surrogate manifest (observable) variables. In the behavioral sciences, latent variables are analogous to intensive physical variables such as temperature and manifest variables are analogous to extensive physical variables such as distance. Although only one variable at a time can be measured, the variable can have a multidimensional structure that must be understood in order to explain disagreements among different measures of the same variable. The use of Rasch theory to measure latent trait variables can be illustrated with a balance scale metaphor that has randomly added variability in the weights of the objects being measured. Knowledge of the distribution of the randomly added variability provides the theoretical structure for estimating measures from ordinal observation scores (e.g., performance measures or rating scales) using statistical inference. In rehabilitation medicine, the latent variable of primary interest is the patient's functional ability. Functional ability can be estimated from observations of surrogate performance measures (e.g., speed and accuracy) or self-report of the difficulty the patient experiences performing specific activities. A theoretical framework borrowed from project management, called the Activity Breakdown Structure (ABS), guides the choice of activities for assessment, based on the patient's value judgments, to make the observations clinically meaningful. In the case of low vision, the functional ability measure estimated from Rasch analysis of activity difficulty ratings was discovered to be a two-dimensional variable. The two visual function dimensions are independent

    The aim of this study was to assess the outcome of isolated tricuspid regurgitation (TR) and the added value of quantitative evaluation of its severity. TR is of uncertain clinical outcome due to confounding comorbidities. Isolated TR (without significant comorbidities, structural valve disease, significant pulmonary artery systolic pressure elevation by Doppler, or overt cardiac cause) is of unknown clinical outcome. In patients with isolated TR assessed both qualitatively and quantitatively by a proximal isovelocity surface area method, a long-term outcome analysis was conducted. Patients with severe comorbid diseases were excluded. The study involved 353 patients with isolated TR (age 70 years; 33% male; ejection fraction, 63%; all with right ventricular systolic pressure <50 mm Hg). Severe isolated TR was diagnosed in 76 patients (21.5%) qualitatively and 68 patients (19.3%) by quantitative criteria (effective regurgitant orifice [ERO] ≥40 mm(2)). The 10-year survival and cardiac event rates were 63 ± 5% and 29 ± 5%. Severe isolated TR independently predicted higher mortality (adjusted hazard ratio: 1.78 [95% confidence interval (CI): 1.10 to 2.82], p = 0.02 for qualitative definition and 2.67 [95% CI: 1.66 to 4.23] for an ERO ≥40 mm(2), p < 0.0001). The addition of grading by quantitative criteria in nested models eliminated the significance of the qualitative grading and improved the model prediction (p < 0.001 for survival and p = 0.02 for cardiac events). The 10-year survival rate was lower with an ERO ≥40 mm(2) versus <40 mm(2) (38 ± 7% vs. 70 ± 6%; p < 0.0001), independent of all characteristics, right ventricular size or function, comorbidity, or pulmonary pressure (p < 0.0001 for all), and lower than expected in the general population (p < 0.001). Freedom from cardiac events was lower with an ERO ≥40 mm(2) versus <40 mm(2) independently of all characteristics, right ventricular size or function, comorbidity, or pulmonary

    To investigate the clinical characteristics, adverse drug reactions, and outcomes of the oldest old patients (aged ≥80 years) with tuberculosis (TB) treated with rifampicin, isoniazid, and pyrazinamide (RIP)-containing regimens. A retrospective chart review study. A 1,200-bed tertiary teaching hospital in southwest Taiwan. We conducted a retrospective observational study between January 1, 2005 and December 31, 2011. Seven hundred adult patients (aged ≥18 years) with TB treated with RIP-containing anti-TB regimens were reviewed, including 161 oldest old patients. Clinical outcomes included clinical responsiveness and microbiological eradication. Adverse outcomes included drug-induced hepatitis, and other symptoms included gastrointestinal upset (eg, abdominal pain, vomiting, diarrhea, or dyspepsia), skin rash, joint pain, and hyperuricemia. Compared with the non-oldest old adult patients, the oldest old patients more frequently had hepatitis (P=0.014), gastrointestinal upset (P=0.029), and unfavorable outcomes (P<0.001). In a multivariate analysis, hepatitis during treatment (adjusted odds ratio: 3.482, 95% confidence interval: 1.537-7.885; P<0.003) and oldest old age (adjusted odds ratio: 5.161, 95% confidence interval: 2.294-11.613; P<0.010) were independent risk factors for unfavorable outcomes. In the oldest old patients with hepatitis, rifampicin use was more common in the favorable outcome group than in the unfavorable outcome group (100% vs 37.5%; P=0.001). The oldest old age and hepatitis during RIP treatment were associated with unfavorable outcomes. For the oldest old patients with TB having hepatitis during treatment, rifampicin rechallenge and use might benefit the treatment outcome.

    Despite the availability of various surgical options, management of laryngotracheal stenosis (LTS) still remains an enigma. Proper selection of surgical technique in each clinical setting is the key for successful outcome. The purpose of this article is to guide one in selection of appropriate surgical procedures depending upon various stenosis parameters. Aim To record the clinical profile of cases with LTS. To assess the outcome following various surgical interventions based on site, severity, cause of stenosis and to derive conclusions regarding treatment options in various stenosis. Materials and Methods It is a study of 60 cases with chronic LTS. It includes retrospective study of 30 cases treated from 2004 and prospective study of 30 cases from Jan 2007 to Dec 2009. A total of 60 cases with LTS were enrolled in the study. Patients were assessed clinically by eliciting detailed history and analyzing previous records. After assessment of extent of stenosis, they were subjected to surgical interventions (endoscopic/open approach). Outcome after surgical interventions was assessed. Results 60 patients were included in the study, in the age group of 2.5-50 years. There were 46 (77%) male patients and 14 (23%) female patients. Intrinsic trauma, secondary to prolonged intubation was the most common cause of LTS, seen in 23 (38%) cases followed by post traumatic stenosis (strangulation-18 (30%), blunt injury-15 (25%), penetrating neck injury-4 (7%)). Stenosis was divided into 6 types based on subsite involvement. Of which, cervical trachea was the commonest site of involvement (25/60 cases). Majority of cases had fixed vocal cords at presentation (55%), more commonly due to post traumatic injury. 60 cases had undergone a total of 110 surgical procedures (endoscopic-56,open approach-54). In the end, overall decannulation rate is 93.3%. In site wise tracheal stenosis, isolated subglottis, combined glottis and subglottic stenosis had decannulation rate of 100% each and

  16. Favor referential representations.

    Frazier, L; McNamara, P

    Avrutin and Hickok (1993) argue that agrammatic patients have the ability to represent nonreferential or "government" chains ("who ... e") but not referential or "binding" chains ("which girl ... e"). By contrast, we propose the "referential representation hypothesis," which suggests that agrammatics attempt to cope with their well-known capacity limitations by favoring referential or content-based representations. This predicts that agrammatic patients' performance should degrade noticeably as task demands increase, and referential demands should take priority over computational ones. In a semantic task, referential phrases should lead to better or more accurate performances. In syntactic tasks, the availability of a referential or content-based representation will interfere with the development of a syntactic representation, resulting in worse syntactic performance on the referential phrases than on nonreferential ones. This predicts that agrammatic patients should incorrectly accept (resumptive) pronoun sentences with a referential wh-phrase because the pronouns will find the semantic or discourse referent of the referential wh-phrase and take it as an antecedent for the pronoun. However, they should reject a (resumptive) pronoun in a sentence with the nonreferential question constituent "who" or "what." "Who" and "what" will remain in syntactic form, since they have only grammatical content and therefore will have only a "nonreferential" syntactic representation. Consequently, they cannot serve as the antecedent of the pronoun. These predictions were largely confirmed by the results of a grammaticality judgement study. Agrammatics performed well on questions with pragmatic biases but failed to distinguish reliably between grammatical and ungrammatical questions where pragmatic biases were neutralized. They assigned especially low ratings to object gap sentences with referential wh-constituents, as predicted. They assigned relatively high ratings to

    The purpose of this study was to investigate the influence of plate location during ulna shortening osteotomy on the incidence of hardware irritation and clinical outcome. Forty patients (17 women, 23 men; mean age, 47 years) who underwent a shortening osteotomy of the ulna due to idiopathic ulna impaction syndrome were examined after a mean of 36 months. All complications and secondary procedures were extracted from the patients' records. The rate of hardware removal was higher in patients who had a dorsal placement of the plate in comparison with ulnar or palmar placements, although this difference was not statistically significant. Apart from hardware irritation, there were 4 nonunions, 1 secondary osteoarthritis of the distal radioulnar joint, and 1 case of chronic irritation of the dorsal branch of the ulnar nerve, which required secondary surgery. The incidence of secondary surgery other than hardware removal was not significantly related to the original location of the plate. Secondary surgery after ulnar shortening osteotomy is common. However, we found no difference in clinical outcomes based on plate location.

    Staphylococcus aureus bacteraemia (SAB) is commonly complicated by metastatic infection or relapse after treatment. Objectives. The study aim was to determine the role of bacterial, host, and management factors in development of complicated SAB. Methods. A prospectively-conducted observational study gathered data on predisposition, management and outcome of 100 consecutive SAB cases. Antibiotic susceptibilities and genetic lineage of bacterial isolates were determined. Further clinical and microbiological data were gathered on two retrospective series from 1999-2000 (n = 57) and 2004 (n = 116). Results. In the prospective cases, 27% met our definition of complicated disease. Expressed as RR and 95% CI, complicated disease was associated with diabetes (1.58, 1.00-2.48), injecting-drug use (5.48, 0.88-33.49), community-onset of symptoms (1.4, 1.02-1.92), and symptom duration >/=48 hours prior to starting effective antibiotic therapy (2.10, 1.22-3.61). Uncomplicated disease was associated with the presence of a central line (0.69, 0.55-0.88) and prompt removal of a primary focus (0.71, 0.57-0.90). Neither methicillin resistance nor genetic lineage was associated with complicated disease, but methicillin resistance was associated with higher mortality. Conclusions. This study demonstrates that clinical rather than microbial factors are the major determinants of SAB outcome and underscores the importance of early treatment.

    In recent decades there has been an increase in the methadone dosages prescribed for opioid dependent women during pregnancy. Using prospective longitudinal data from a cohort of 32 methadone exposed and 42 non-methadone exposed infants, this study examined the relationship between maternal methadone dose during pregnancy and a range of infant clinical outcomes. Of particular interest was the extent to which any observed associations might reflect the direct causal effects of maternal methadone dose and/or the confounding effects of adverse maternal lifestyle factors correlated with methadone use during pregnancy. Findings revealed the presence of clear linear relationships between the mean methadone dose prescribed for mothers during pregnancy and a range of adverse infant clinical outcomes. With increasing maternal methadone dose there was a corresponding increase in infants' risk of being born preterm, being symmetrically smaller, spending longer periods in hospital and the need for treatment for Neonatal Abstinence Syndrome. After due allowance for potentially confounding maternal health and lifestyle factors, maternal methadone dose during pregnancy remained a significant predictor of preterm birth, growth, and the duration of infant hospitalization post delivery. These findings suggest a need to examine more closely the potential impacts of recent trends towards the use of higher methadone dose levels during pregnancy.

    Chronic obstructive pulmonary disease (COPD) is a moderate risk factor for venous thromboembolism (VTE), but neither the clinical presentation nor the outcome of VTE in COPD patients is well known. The clinical presentation of VTE, namely pulmonary embolism (PE) or deep venous thrombosis (DVT), and the outcome at 3 months (death, recurrent VTE or bleeding) were compared between 2,984 COPD patients and 25,936 non-COPD patients included in the RIETE (Registro Informatizado de la Enfermedad TromboEmbólica) registry. This ongoing international, multi-centre registry includes patients with proven symptomatic PE or DVT. PE was the more frequent VTE presentation in COPD patients (n = 1,761, 59%). PE presentation was more significantly associated with COPD patients than non-COPD patients (OR 1.64, 95% CI 1.49-1.80). During the 3-month follow-up, mortality (10.8% versus 7.6%), minor bleeding (4.5% versus 2.3%) or first VTE recurrences as PE (1.5% versus 1.1%) were significantly higher in COPD patients than in non-COPD patients. PE was the most common cause of death. COPD patients presented more frequently with PE than DVT. It may explain the worse prognosis of COPD patients, with a higher risk of death, bleeding or VTE recurrences as PE compared with non-COPD patients. Further therapeutic options are needed.

    Background To assess the efficacy, clinical outcomes, visual acuity (VA), incidence of adverse effects, and complications of peripheral iris fixation of 3-piece acrylic IOLs in eyes lacking capsular support. Thirteen patients who underwent implantation and peripheral iris fixation of a 3-piece foldable acrylic PC IOL for aphakia in the absence of capsular support were followed after surgery. Clinical outcomes and macular SD-OCT (Cirrus OCT; Carl Zeiss Meditec, Germany) were analyzed. Findings The final CDVA was 20/40 or better in 8 eyes (62%), 20/60 or better in 12 eyes (92%), and one case of 20/80 due to corneal astigmatism and mild persistent edema. No intraoperative complications were reported. There were seven cases of medically controlled ocular hypertension after surgery due to the presence of viscoelastic in the AC. There were no cases of cystoid macular edema, chronic iridocyclitis, IOL subluxation, pigment dispersion, or glaucoma. Macular edema did not develop in any case by means of SD-OCT. Conclusions We think that this technique for iris suture fixation provides safe and effective results. Patients had substantial improvements in UDVA and CDVA. This surgical strategy may be individualized however; age, cornea status, angle structures, iris anatomy, and glaucoma are important considerations in selecting candidates for an appropriate IOL fixation method.

We aim to describe the clinical presentation and visual outcome of ocular bartonellosis in Malaysia. Materials and Methods. This was a retrospective review of patients treated for ocular bartonellosis in two ophthalmology centers in Malaysia between January 2013 and December 2015. The diagnosis was based on clinical features, supported by a positive Bartonella spp. serology. Results. Of the 19 patients in our series, females were predominant (63.2%). The mean age was 29.3 years. The majority (63.2%) had unilateral involvement. Five patients (26.3%) had a history of contact with cats. Neuroretinitis was the most common presentation (62.5%). Azithromycin was the antibiotic of choice (42.1%). Concurrent systemic corticosteroids were used in approximately 60% of cases. The presenting visual acuity was worse than 6/18 in approximately 60% of eyes; on final review, 76.9% of eyes had a visual acuity better than 6/18. Conclusion. Ocular bartonellosis tends to present with neuroretinitis. Azithromycin is a viable option for treatment. Systemic corticosteroids may be considered in those with poor visual acuity on presentation.

    Pancreatic fistula continues to be a common complication following PD. This study seeks to identify clinical factors which may predict pancreatic fistula (PF) and evaluate the effect of PF on outcomes following pancreaticoduodenectomy (PD). We performed a retrospective analysis of a clinical database at an academic tertiary care hospital with a high volume of pancreatic surgery. Five hundred ten consecutive patients underwent PD, and PF occurred in 46 patients (9%). Perioperative mortality of patients with PF was 0%. Forty-five of 46 PF (98%) closed without reoperation with a mean time to closure of 34 days. Patients who developed PF showed a higher incidence of wound infection, intra-abdominal abscess, need for reoperation, and hospital length of stay. Multivariate analysis demonstrated an invaginated pancreatic anastomosis and closed suction intraperitoneal drainage were associated with PF whereas a diagnosis of chronic pancreatitis and endoscopic stenting conferred protection. Development of PF following PD in this series was predicted by gender, preoperative stenting, pancreatic anastomotic technique, and pancreas pathology. Outcomes in patients with PF are remarkable for a higher rate of septic complications, longer hospital stays, but in this study, no increased mortality. PMID:19461951

    This paper identifies instruments and measures that may be appropriate for randomized clinical trials in participants with autism spectrum disorders (ASDs). The Clinical Global Impressions scale was recommended for all randomized clinical trials. At this point, however, there is no “perfect” choice of outcome measure for core features of autism, although we will discuss five measures of potential utility. Several communication instruments are recommended, based in part on suitability across the age range. In trials where the intention is to alter core features of ASDs, adaptive behavior scales are also worthy of consideration. Several “behavior complexes” common to ASDs are identified, and instruments are recommended for assessment of these. Given the prevalence of cognitive impairment in ASDs, it is important to assess any cognitive effects, although cognitive data from ASD randomized clinical trials, thus far, are minimal. Guidance from trials in related pharmacologic areas and behavioral pharmacology may be helpful. We recommend routine elicitation of side effects, height and weight, vital signs, and (in the case of antipsychotics) extrapyramidal side-effects assessment. It is often appropriate to include laboratory tests and assessments for continence and sleep pattern. PMID:14999174

    Takotsubo cardiomyopathy (TCM) has been associated with repolarization abnormalities including QT prolongation and acquired long QT syndrome. However, the association between QT prolongation and clinical outcomes in patients with TCM remains unclear. The aim of this study is to examine the association between QT prolongation and ventricular arrhythmias, cardiogenic shock, and death in patients with TCM. Forty-six patients with TCM met our inclusion criteria in an ongoing prospective cohort database from 2010 to May 2015. We assigned the patients to a long QT group or a normal QT group, and created a composite outcome consisting of ventricular arrhythmias, cardiogenic shock, or death. The mean age of the participants was 59.7 ± 16 years, 67% were women, and 63% had hypertension. Median follow-up time was 3.1 years (interquartile range: 2.0-3.8), with a total of 133.8 person-years. The mean left ventricular ejection fraction at diagnosis was 27.2% ± 1.4%. The mean QTc on diagnosis was 484 ms ± 10.2 ms for men, and 488 ms ± 8.6 ms for women. The long QT group had a 4.1-times higher odds of having the composite clinical outcome as compared to the normal QT group (95% confidence interval: 1.1, 16.1, P = 0.04) after adjusting for age and race in logistic regression. Patients with TCM who have a long QT interval or develop acquired long QT syndrome due to TCM may be more likely to be intubated; require vasopressors; and develop shock, ventricular arrhythmias, and death than those with a normal QT interval. ©2016 Wiley Periodicals, Inc.

    Purpose In this study the authors evaluate the clinical outcomes in patients with radial nerve palsy who underwent nerve transfers utilizing redundant fascicles of median nerve (innervating the flexor digitorum superficialis and flexor carpi radialis muscles) to the posterior interosseous nerve and the nerve to the extensor carpi radialis brevis. Methods A retrospective review of the clinical records of 19 patients with radial nerve injuries who underwent nerve transfer procedures using the median nerve as a donor nerve were included. All patients were evaluated using the Medical Research Council (MRC) grading system. Results The mean age of patients was 41 years (range 17 – 78 years). All patients received at least 12 months of follow-up (20.3 ± 5.8 months). Surgery was performed at a mean of 5.7 ± 1.9 months post-injury. Post-operative functional evaluation was graded according to the following scale: grades MRC 0/5 - MRC 2/5 were considered poor outcomes, while MRC of 3/5 was a fair result, MRC grade 4/5 was a good result, and grade 4+/5 was considered an excellent outcome. Seventeen patients (89%) had a complete radial nerve palsy while two patients (11%) had intact wrist extension but no finger or thumb extension. Post-operatively all patients except one had good to excellent recovery of wrist extension. Twelve patients recovered good to excellent finger and thumb extension, two patients had fair recovery, five patients had a poor recovery. Conclusions The radial nerve is a commonly injured nerve, causing significant morbidity in affected patients. The median nerve provides a reliable source of donor nerve fascicles for radial nerve reinnervation. This transfer was first performed in 1999 and evolved over the subsequent decade. The important nuances of both surgical technique and motor re-education critical for to the success of this transfer have been identified and are discussed. PMID:21168979

    Objectives: Neurofibromatosis (NF) is a genetic disease with multiple clinical manifestations that can significantly impact quality of life (QOL). Clinical trials should include patient-reported outcomes (PROs) as endpoints to assess treatment effects on various aspects of QOL, but there is no consensus on the selection and use of such measures in NF. This article describes the PRO Working Group of the Response Evaluation in Neurofibromatosis and Schwannomatosis (REiNS) Collaboration, its main goals, methods for identifying appropriate PRO measures for NF clinical trials, and recommendations for assessing pain intensity. Methods: The REiNS PRO group selected core endpoint domains important to assess in NF. The members developed criteria to rate PRO measures, including patient characteristics, psychometric properties, and feasibility, and utilized a systematic process to evaluate PROs for NF clinical trials. Within the subdomain of pain intensity, the group reviewed the Numerical Rating Scale-11 (NRS-11), the Visual Analogue Scale, and the Faces Pain Scale-Revised using this process. Results: Based on the review criteria, each of these pain intensity scales is brief, reliable, valid, and widely used. However, the NRS-11 was given the highest rating for use in NF clinical trials due to recommendations from pain experts and other consensus groups, its extensive use in research, strong psychometric data including sensitivity to change, and excellent feasibility in ages ≥8 years. Conclusions: The systematic review criteria and process are effective for identifying appropriate PRO measures and provide information utilized by the REiNS Collaboration to achieve consensus regarding PROs in NF clinical trials.

    Racial and ethnic disparities among North American patients with chronic kidney disease have received significant attention. In contrast, little is known about health-related outcomes of patients with end-stage renal disease among the Roma minority, also known as gypsies, compared to Caucasian individuals. We prospectively assessed the association between Roma ethnicity and long-term clinical outcomes in kidney transplant recipients. In a prevalent cohort of renal transplant recipients, followed up over a median of 94 months, we prospectively collected socio-demographic, medical (and transplant related) characteristics and laboratory data at baseline from 60 Roma and 1,003 Caucasian patients (mean age 45 (SD = 11) and 49 (SD = 13) years, 33 and 41% women, 18 and 17% with diabetes mellitus, respectively). Survival analyses examined the associations between Roma ethnicity and all-cause mortality and death-censored graft loss or death with functioning renal allograft. During the follow-up period, 341 patients (32%) died. Two-hundred eighty (26%) patients died with a functioning graft and 201 patients (19%) returned to dialysis. After multivariable adjustments, Roma ethnicity was associated with 77% higher risk of all-cause mortality (Hazard Ratio (HR): 1.77; 95% confidence interval (CI): 1.02, 3.07), two times higher risk of mortality with functioning graft (2.04 [1.17-3.55]) and 77% higher risk of graft loss (1.77 [1.01-3.13]), respectively. Roma ethnicity is independently associated with increased mortality risk and worse graft outcome in kidney transplant recipients. Further studies should identify the factors contributing to worse outcomes among Roma patients.

    Human papillomavirus (HPV) is an important factor for the development of tonsillar squamous cell carcinoma (TSCC). In addition, patients with HPV-positive TSCC have a better clinical outcome than patients with HPV-negative TSCC. Although, HPV is an important prognostic marker, additional biomarkers are needed to better predict clinical outcome to individualize treatment. Hence, we examined if classical HLA HLA-A,B,C and nonclassical HLA-E,G could serve as such marker. Formalin-fixed paraffin-embedded TSCC from 150 patients diagnosed 2000-2006, earlier analyzed for HPV DNA and p16(INK4a), and treated with intention to cure were evaluated for the expression of HLA-A,B,C and HLA-E,G by immunohistochemistry. For HPV-positive TSCC a low expression of HLA-A,B,C, whereas for HPV-negative TSCC, a normal expression of HLA-A,B,C was significantly correlated to a favorable clinical outcome. These correlations were more pronounced for membrane staining of HLA-A,B,C when compared with cytoplasmatic staining. No significant correlation was found between HLA-E,G and HPV status or clinical outcome. The unexpected contrasting correlation between HLA-A,B,C expression, and clinical outcome depending on HPV, indicates essential differences between HPV-positive and HPV-negative TSCC. Furthermore, our data demonstrate that for both HPV-positive and HPV-negative TSCC, the expression of HLA-A,B,C together with HPV may serve as a useful biomarker for predicting clinical outcome.

    We hypothesized performance improvement interventions would improve COPD guideline-recommended care and decrease COPD exacerbations in primary care clinic practices. We initiated a performance improvement project in 12 clinics to improve COPD outcomes incorporating physician education, case management, web-based decision support (CareManager(TM)), and performance feedback. We collected baseline and one-year follow up data on 242 patients who had COPD with acute exacerbations. We analyzed data by two methods. First, the 12 clinics were cluster randomized to 4 intervention (117 patients) and 8 control (125 patients) clinics which all had access to CareManager(TM) but only intervention clinic physicians received case management, academic detailing, and decision support assistance. Exacerbation rates and guideline adherence were compared. Second, data from all 12 clinics were pooled in a quasi-experimental design comparing baseline and post-implementation of CareManager(TM) to determine the value of system-wide performance improvement during the study period. In the randomized analysis, baseline demographics were similar. No differences (p = 0.79) occurred in exacerbation rates between intervention and control clinics although both groups had decreased numbers of exacerbations from baseline to follow up (p < 0.05). The pooled data from all 12 clinics demonstrated a reduction (p < 0.05) in mean exacerbations/patient from 2.3 (CI 2.0-2.6) during baseline to 1.4 (CI 1.1-1.7) at one-year follow up. Emergency department visits and hospitalizations/patient decreased (p = 0.003). Patients naïve at study start to depression screening, pneumococcal vaccination, inhaled control medications or smoking cessation had fewer (p < 0.05) exacerbations after these interventions. We observed no difference in exacerbation rates between clinics receiving case management, academic detailing, and ongoing assistance with decision support and controls.

    Abstract Clinicopathologic features and clinical outcomes of gastrointestinal stromal tumors (GISTs) in esophagus are limited, because of the relatively rare incidence of esophageal GISTs. Therefore, the aim of the current study was to investigate the clinicopathologic features and clinical outcomes of esophageal GISTs, and to investigate the potential factors that may predict prognosis. Esophageal GIST cases were obtained from our center and from case reports and clinical studies extracted from MEDLINE. Clinicopathologic features and survivals were analyzed and compared with gastric GISTs from our center. The most common location was lower esophagus (86.84%), followed by middle and upper esophagus (11.40% and 1.76%). The majority of esophageal GISTs were classified as high-risk category (70.83%). Mitotic index was correlated with histologic type, mutational status, and tumor size. The 5-year disease-free survival and disease-specific survival were 65.1% and 65.9%, respectively. Tumor size, mitotic index, and National Institutes of Health risk classification were associated with prognosis of esophageal GISTs. Only tumor size, however, was the independent risk factor for the prognosis of esophageal GISTs. In comparison to gastric GISTs, the distribution of tumor size, histologic type, and National Institutes of Health risk classification were significantly different between esophageal GISTs and gastric GISTs. The disease-free survival and disease-specific survival of esophageal GISTs were significantly lower than that of gastric GISTs. The most common location for esophageal GISTs was lower esophagus, and most of the esophageal GISTs are high-risk category. Tumor size was the independent risk factor for the prognosis of esophageal GISTs. Esophageal GISTs differ significantly from gastric GISTs in respect to clinicopathologic features. The prognosis of esophageal GISTs was worse than that of gastric GISTs. PMID:26765432

    Friedreich ataxia (FRDA) is an inherited neurodegenerative disease characterized by ataxia and cardiomyopathy. Homozygous GAA trinucleotide repeat expansions in the first intron of FXN occur in 96% of affected individuals and reduce frataxin expression. Remaining individuals are compound heterozygous for a GAA expansion and a FXN point/insertion/deletion mutation. We examined disease-causing mutations and the impact on frataxin structure/function and clinical outcome in FRDA. We compared clinical information from 111 compound heterozygotes and 131 individuals with homozygous expansions. Frataxin mutations were examined using structural modeling, stability analyses and systematic literature review, and categorized into four groups: (1) homozygous expansions, and three compound heterozygote groups; (2) null (no frataxin produced); (3) moderate/strong impact; and (4) minimal impact. Mean age of onset and the presence of cardiomyopathy and diabetes mellitus were compared using regression analyses. Mutations in the hydrophobic core of frataxin affected stability whereas surface residue mutations affected interactions with iron sulfur cluster assembly and heme biosynthetic proteins. The null group of compound heterozygotes had significantly earlier age of onset and increased diabetes mellitus, compared to the homozygous expansion group. There were no significant differences in mean age of onset between homozygotes and the minimal and moderate/strong impact groups. In compound heterozygotes, expression of partially functional mutant frataxin delays age of onset and reduces diabetes mellitus, compared to those with no frataxin expression from the non-expanded allele. This integrated analysis of categorized frataxin mutations and their correlation with clinical outcome provide a definitive resource for investigating disease pathogenesis in FRDA. © 2016 American Neurological Association.

    Patients with Disorders of consciousness, are persons with extremely low functioning levels and represent a challenge for health care systems due to their high needs of facilitating environmental factors. Despite a common Italian health care pathway for these patients, no studies have analyzed information on how each region have implemented it in its welfare system correlating data with patients' clinical outcomes. A multicenter observational pilot study was realized. Clinicians collected data on the care pathways of patients with Disorder of consciousness by asking 90 patients' caregivers to complete an ad hoc questionnaire through a structured phone interview. Questionnaire consisted of three sections: sociodemographic data, description of the care pathway done by the patient, and caregiver evaluation of health services and information received. Seventy-three patients were analyzed. Length of hospital stay was different across the health care models and it was associated with improvement in clinical diagnosis. In long-term care units, the diagnosis at admission and the number of caregivers available for each patient (median value = 3) showed an indirect relationship with worsening probability in clinical outcome. Caregivers reported that communication with professionals (42%) and the answer to the need of information were the most critical points in the acute phase, whereas presence of Non-Governmental Organizations (25%) and availability of psychologists for caregivers (21%) were often missing during long-term care. The 65% of caregivers reported they did not know the UN Convention on the Rights of Persons with Disabilities. This study highlights relevant differences in analyzed models, despite a recommended national pathway of care. Future public health considerations and actions are needed to guarantee equity and standardization of the care process in all European countries.

    Accurate identification of patients who will achieve a favorable outcome is almost impossible preoperatively or postoperatively in poor-grade (Hunt and Hess Grade IV and V) aneurysmal subarachnoid hemorrhage (SAH). Whether characteristics of blood pressure profiles during the first 24 hours after endovascular coiling could predict prognosis in poor grade patients was explored. Data were obtained retrospectively on all patients undergoing endovascular treatment with poor-grade SAH from November 2011 to June 2016. Blood pressure during the initial 24 hours was measured at 2-hour intervals after coil embolization. Studied features of mean systolic blood pressure (MSBP) and systolic blood pressure variability (SBPV) as well as demographics, medical history, clinical characteristics, and neurologic outcomes were documented. SBPV was determined as standard deviation and successive variation of systolic blood pressure. Logistic regression analysis was used to identify predictors of favorable outcome assessed on modified Rankin Scale score of 0 to 2. The patients with favorable and unfavorable outcome were comparable with respect to systolic blood pressure on admission and MSBP after coiling. However, MSBP between 120 and 140 mm Hg was one of independent predictors of good outcomes at discharge (odds ratio 7.1; P = 0.002). SBPV-successive variation after embolization was associated with functional recovery (odds ratio 0.87; P = 0.011) in multivariate logistic analysis and mortality by Cox proportional hazard regression (hazard ratio, 1.10; P = 0.001) at 6-month follow-up. Characteristics of blood pressure profiles after coiling appeared to be simple and convenient indexes for the prognosis of patients with poor-grade SAH. Copyright © 2017 Elsevier Inc.

Analysis of the literature, in addition to our overall experience, indicates that epileptic blindness in children is associated with a favorable outcome providing prompt diagnosis and treatment of the associated seizures or epileptic syndrome. This resulted in complete and long-standing resolution of blindness in all children together with satisfactory control of seizures. As such, we recommend a prompt EEG in any child presenting acute visual obscuration, even in the absence of additional overt epileptic phenomena.

    To investigate the clinical effect of extracorporeal shock wave therapy (ESWT) in patients with secondary lymphedema after breast cancer treatment. In a prospective clinical trial, ESWT was performed consecutively 4 times over two weeks in 7 patients who were diagnosed with stage 3 secondary lymphedema after breast cancer treatment. Each patient was treated with four sessions of ESWT (0.056-0.068 mJ/mm(2), 2,000 impulses). The parameters were the circumference of the arm, thickness of the skin and volume of the arm. We measured these parameters with baseline values before ESWT and repeated the evaluation after each ESWT treatment. Subjective data on skin thickness, edema and sensory impairment were obtained using a visual analogue scale (VAS). The mean volume of the affected arm after four consecutive ESWT was significantly reduced from 2,332 to 2,144 mL (p<0.05). The circumference and thickness of the skin fold of the affected arm were significantly decreased after the fourth ESWT (p<0.05). The three VAS scores were significantly improved after the fourth ESWT. Almost all patients were satisfied with this treatment and felt softer texture in their affected arm after treatment. ESWT is an effective modality in the treatment of stage 3 lymphedema after breast cancer treatment. ESWT reduced the circumference and the thickness of arms with lymphedema and satisfied almost all patients with lymphedema. Therefore, this treatment provides clinically favorable outcome to patients with breast cancer-related lymphedema.

    Patient reported outcomes (PROs) are increasingly being implemented into the care of patients with cancer. The use of a standard set of PROs (e.g., pain) in cancer is becoming established and there is interest in what additional PROs might provide valuable information. The goal of this observational study was to examine how the PROs of self-efficacy for pain and other symptoms assessed at the point of service were associated with pain, symptom severity and distress, and physical and psychosocial functioning in a sample of breast and gastrointestinal patients. We also sought to examine differences in these relationships by cancer type (breast and gastrointestinal) as well as understand differences in self-assessment mode (paper/pencil or electronic tablet). 178 patients with breast (n=65) and gastrointestinal cancer (n = 113) completed the Chronic Pain Self Efficacy Scale, M.D. Anderson Symptom Inventory, and Functional Assessment of Cancer Therapy-General questionnaires. Measures were completed with paper and pencil and electronically using a tablet computer while patients waited for their clinical appointment. Responses from the initial completed questionnaires on both the paper and electronic instruments were analyzed. Patients' self-efficacy scores for pain and other symptoms correlated positively with pain, symptom severity and distress, and physical and psychosocial functioning; patients with lower levels of self-efficacy reported poorer outcomes and functioning overall. The results were independent of cancer type and mode of assessment. No statistically significant differences were found in the PROs when collected by electronic technology versus paper-pencil mode; patients were very satisfied with using the tablet computer to complete the PRO measures. Our results suggest that self-efficacy for pain and symptom management may be a beneficial addition to clinic-based PRO assessment batteries for patients with cancer and other chronic diseases.

    When conservative treatment fails to provide relief for a symptomatic accessory navicular, surgical intervention may be necessary. Numerous studies have been published, reporting the results of the traditional Kidner procedure and alternative surgical techniques, all of which produce mostly satisfactory clinical outcomes. The purpose of this study was to report the clinical results, utilizing the American Orthopaedic Foot and Ankle Society (AOFAS) Midfoot Scale, of surgical management for symptomatic accessory navicular with simple excision and anatomic repair of the tibialis posterior tendon. The authors retrospectively reviewed the results of 13 consecutive patients (14 feet) who underwent surgical treatment for symptomatic accessory navicular. The patients ranged in age from 16 to 64 years (average, 34.1 years; mean, 28.2 years) at the time of surgery. All patients had a type II accessory navicular. The average follow-up of the patients involved in the study was 103.4 months (range, 45-194 months). The AOFAS Midfoot Scale was utilized to determine both preoperative and postoperative clinical status of the 14 feet included in the study. The average preoperative AOFAS score was 48.2 (range, 20-75; mean, 38.8). The average postoperative AOFAS score was 94.5 (range, 83-100; mean, 94.3). At last follow-up, 13 of 14 feet were without any pain, no patients had activity limitations, and only two of 14 feet required shoe insert modification. Postoperatively, no patients had a clinically notable change in their preoperative midfoot longitudinal arch alignment. All of the patients in the study were satisfied with the outcome of their surgery and would undergo the same operation again under similar circumstances. When conservative measures fail to relieve the symptoms of a painful accessory navicular, simple excision of the accessory navicular and anatomic repair of the posterior tibialis tendon is a successful intervention. Overall, the procedure provides reliable pain

    The treatment of popliteal artery injury (PAI) caused by blunt or penetrating mechanism is demanding. Concomitant injuries and prolonged ischemia are the major causes of lower extremity morbidity and poor rates of limb salvage. This study assessed the amputation rate and, subsequently, the therapeutic management and clinical outcomes regarding the affect of concomitant injuries among patients with PAI in a setting of central European trauma care. Sixty-four patients (20 female and 44 male), with an average age of 44 years (range, 17-79 years) at the time of injury, were evaluated for clinical characteristics, concomitant injuries, complications, amputation rates, and functional outcome after traumatic PAI. The mechanism of injury was blunt trauma in 35 patients (54.7%) and penetrating trauma in 29 (45.3%). The Mangled Extremity Severity Score and the Injury Severity Score were assessed initially and the modified Functional Independence Measure (FIM) Score at 12 months after the primary surgery. Thirty patients (47%) returned to their normal activity level within 1 year after trauma, and 16 (25%) were limited in their daily activity or suffered from chronic pain symptoms. Within the blunt trauma group 26 of 35 patients (74%) sustained severe concomitant injuries, whereas two of 29 patients (7%) in the penetrating group showed severe concomitant injuries (P < .046). Eleven patients (17%) had to undergo revision surgery due to their associated injuries. The median modified FIM score was 10.3, whereas patients with blunt trauma had significantly lower FIM score (P < .0082). The median Mangled Extremity Severity Score was 6 points (range, 6-16 points). Primary or secondary amputation was required in 18 patients (28%) due to failure of revascularization. Patients who sustained blunt trauma had significantly higher amputation rates than those with penetrating injuries (P < .035). Clinical outcome and limb salvage of patients with PAI were influenced by the mechanism of

    This study was performed to determine the favorable effects of garlic on metabolic status and pregnancy outcomes among pregnant women at risk for pre-eclampsia. This randomized, double-blind, placebo-controlled trial was conducted among 44 pregnant women, primigravida, aged 18-40 years old at 27 weeks' gestation with positive roll-over test. Participants were randomly assigned to receive either one garlic tablet (equal to 400 mg garlic and 1 mg allicin) (n = 22) or placebo (n = 22) once daily for 9 weeks. Fasting blood samples were taken at baseline and after 9 weeks' intervention to measure metabolic profiles and biomarkers of oxidative stress. Administration of garlic compared with the placebo resulted in decreased levels of serum high sensitivity C-reactive protein (hs-CRP) (-1425.90 versus 1360.50 ng/mL, p = 0.01) and increased plasma glutathione (GSH) (+98.10 versus. -49.87 µmol/l, p = 0.03). A trend toward a significant effect of garlic intake on reducing fasting plasma glucose (FPG) (p = 0.07), insulin (p = 0.09) and increasing quantitative insulin sensitivity check (QUICKI) (p = 0.05) was also observed. Consumption of garlic for 9 weeks among pregnant women at risk for pre-eclampsia led to decreased hs-CRP and increased GSH, but did not affect lipid profiles, total antioxidant capacity (TAC) and pregnancy outcomes.

    The purpose of the current study was to identify clinical and kidney morphologic features that predict a favorable blood pressure (BP) response to renal artery stenting (RAS). The study cohort consisted of 149 patients who underwent primary RAS over 9 years. Patients were categorized as "responders" based on modified American Heart Association guidelines: BP <160/90 mm Hg on fewer antihypertensive medications or diastolic BP <90 mm Hg on the same medications. All other patients were deemed "nonresponders." Renal volume was estimated as kidney length × width × depth/2 based on preoperative computed tomography or magnetic resonance scans. Median follow-up was 19 months (interquartile range [IQR] 10.0-29.5 months). The median age of the cohort was 68 years (IQR, 60-74 years). A favorable BP response was observed in 50 of 149 patients (34%). Multivariate analysis identified three independent predictors of a positive BP response: (1) requirement for four or more medications (odds ratio, 29.9; P = .0001), (2) preoperative diastolic BP >90 mm Hg (OR, 31.4; P = .0011), and (3) preoperative clonidine use (OR, 7.3; P = .029). The BP response rate varied significantly based on the number of predictors present per patient (P < .0001). Among patients with three-drug hypertension, a larger ipsilateral kidney (volume ≥150 cm(3)) increased the BP response rate more than threefold compared with patients with smaller kidneys (63% vs 18% BP response rate; P = .018). The current study demonstrated that three clinical predictors (≥4 antihypertensive medications, diastolic BP ≥90 mm Hg, and clonidine use) are preoperative predictors of BP response to RAS. Kidney volume may help in discriminating responders from nonresponders among those patients with three-drug hypertension. These parameters may assist clinicians in patient selection and provide more concrete data with which to counsel patients on the likely outcomes for RAS. Published by Mosby, Inc.

    Septic polyarthritis is rarer than septic monoarthritis, but associated with higher mortality. Septic polyarthritis may be difficult to distinguish clinically from noninfectious inflammatory arthritis. We describe one of the largest samples of septic polyarthritis with the aim of distinguishing septic monoarthritis from polyarthritis. We conducted a retrospective study of adults admitted to tertiary care with septic monoarthritis and polyarthritis. Baseline characteristics, microbial profiles, joint involvement, length of stay, and 60-day readmission rates were determined. We identified 464 and 42 cases of septic monoarthritis and polyarthritis, respectively, including 7 cases of septic polyarthritis with comorbid rheumatoid arthritis. Compared to those with septic monoarthritis, patients with septic polyarthritis were more likely to have rheumatoid arthritis (p < 0.01), sepsis (p < 0.01), and higher peripheral (p < 0.001) and synovial (p < 0.001) white blood cell counts. Operative intervention rates were similar, but mean length of stay was longer in polyarticular septic arthritis (p < 0.001). Patients with septic polyarthritis with/without underlying rheumatoid arthritis were similar in terms of presenting features and outcomes, except for more frequent immunosuppressive therapy in rheumatoid arthritis (p < 0.01). In this sample of patients with septic arthritis, patients with septic polyarthritis were more likely to have systemic infection at presentation than those with septic monoarthritis. Despite this difference, patients with septic monoarthritis and polyarthritis tended to have similar outcomes. While rheumatoid arthritis was observed more frequently among patients with septic polyarthritis, those with/without underlying rheumatoid arthritis had similar presenting features and outcomes.Bottom of Form.

    The objective of this study is to investigate the factors associated with serum phosphate concentrations in severely burned children and whether hypophosphatemia is associated with outcome. Seventy-eight children with a total body surface area of 24% (6.0-68.5) were retrospectively analyzed for serum phosphate concentrations during the first 10 days of stay in the intensive care unit (ICU). The method of generalized estimating equations was used to evaluate the effect of the exposure variables for serum phosphate concentrations during the study period. Outcome variables were the probability of ICU discharge at 30 days and time on mechanical ventilation. Potential explanatory variables for clinical outcome were hypophosphatemia (serum phosphate <3.8 mg/dL for children <2 years and <3.5 mg/dL for older children), age, sex, percent total body surface area burn, inhalation injury, and severe sepsis and/or septic shock. Competing-risk analysis was applied to calculate the probability of ICU discharge at 30 days, and death was assumed as the competing event. The rate of hypophosphatemia was 79.5%. Serum phosphate concentrations were associated with C-reactive protein (coefficient: -0.63; 95% confidence interval [CI]: -0.96 to -0.30; P = .001). Hypophosphatemia was independently associated with a 68% decrease in the probability of ICU discharge at 30 days (subhazard ratio: -0.32; 95% CI: 0.20, 0.53; P = .001) and an increase of 2.9 days in mechanical ventilation (coefficient: 2.91; 95% CI: 1.16, 4.66; P = .001). Serum phosphate concentrations in pediatric burn patients are associated with the magnitude of inflammatory response. Hypophosphatemia is associated with decreased probability of ICU discharge and increased time on mechanical ventilation.

    Medical schools universally accept the idea that bioethics courses are essential components of education, but few studies which measure outcomes (i.e., knowledge or retention) have demonstrated their educational value in the literature. The goal of this study was to examine whether core concepts of a pre-clinical bioethics course were learned and retained. Over the course of 2 years, a pre-test comprising 25 multiple-choice questions was administered to two classes (2008-2010) of first-year medical students prior to the start of a 15-week ethics course, and an identical post-test was administered at the end of the course. A total of 189 students participated. Paired t tests showed a significant difference between pre-test scores and post-test scores. The pre-test average score was 69.8 %, and the post-test average was 82.6 %, an increase of 12.9 % after the ethics course. The pre- and post-test results also suggested a shift in difficulty level of the questions, with students finding identical questions easier after the intervention. Given the increase in post-test scores after the 15-week intervention, the study suggests that core concepts in medical ethics were learned and retained. These results demonstrate that an introductory bioethics course can improve short-term outcomes in knowledge and comprehension, and should provide impetus to educators to demonstrate improved educational outcomes in ethics at higher levels of B.S.

    The Enjoyment of Sexualization Scale (ESS) was given to 150 lesbians in addition to measures of self-objectification, negative eating attitudes, and depression. The ESS was found to have acceptable levels of internal consistency reliability with a lesbian sample. Scores on the ESS were lower in this sample than in previously reported research with heterosexual women. Enjoying sexualization was found to moderate the relationship between body shame and both depressive symptomatology and negative eating attitudes. In contrast to findings from a heterosexual sample, lesbians who enjoyed sexualization had smaller relationships between these negative clinical outcomes and body shame than lesbians who did not. For lesbians, enjoying sexualization may serve a protective function against the negative effects of self-objectification. Findings are discussed in terms of body image and perceptions of ideal beauty among lesbians.

    OBJECTIVE: To identify prognostic factors of postoperative functional outcomes. METHODS: Retrospective case series evaluating patients undergoing rotator cuff repair, analyzed by the UCLA score (pre and 12-month postoperative) and Magnetic Resonance Imaging (preoperative). Patients' intrinsic variables related to the injury and intervention were evaluated. Multivariate linear regression analysis was performed to determine variables impact on postoperative functional assessment. RESULTS: 131 patients were included. The mean UCLA score increased from 13.17 ± 3.77 to 28.73 ± 6.09 (p<0,001). We obtained 65.7% of good and excellent results. Age (r= 0.232, p= 0.004) and reparability of posterosuperior injuries (r= 0.151, p= 0.043) correlated with the functional assessment at 12 months. After multivariate linear regression analysis, only age was associated (p = 0.008). CONCLUSIONS: The surgical treatment of rotator cuff tears lead to good and excellent results in 65.6% of patients. Age was an independent predictor factor with better clinical outcomes by UCLA score in older patients. Level of Evidence IV, Case Series. PMID:26207092

    The clinical and laboratory features of severe falciparum malaria in 180 Gambian children were studied between 1985 and 1989. Of the 180 children, 118 (66%) presented with seizures, 77 (43%) had cerebral malaria, 35 (20%) had witnessed seizures after admission, 29 (16%) were hypoglycemic, and 27 (15%) died. Respiratory distress was a common harbinger of a fatal outcome. The differences in admission parasite counts in the blood, hematocrit, and opening cerebrospinal pressures for patients who died and survivors were not significant. A multiple logistic regression model identified neurological status (coma, particularly if associated with extensor posturing), stage of parasite development on the peripheral blood film, pulse rate of > 150 or respiratory rate of > 50, hypoglycemia, and hyperlactatemia (plasma lactate level, > 5 mmol/L) as independent indicators of a fatal outcome. Biochemical evidence of hepatic and renal dysfunction was an additional marker of a poor prognosis, but, in contrast to severe malaria in adults, none of these children with severe malaria had acute renal failure.

    Objective: To document the neonatal outcomes of preterm birth in twin pregnancies and to investigate whether perinatal and obstetric parameters are associated with clinical outcomes. Methods: This retrospective trial was conducted on data gathered from 176 preterm twins delivered in the obstetrics and gynecology department of our tertiary care center. Data extracted from medical files of 88 pregnant women who gave preterm birth (at 260/7 to 366/7 gestational weeks) to twins were analyzed. Maternal/fetal descriptive and obstetric parameters, sonographic data, route of delivery, indication for cesarean section, birth weight, Apgar scores, head circumference, umbilical cord length and placental weight were noted. Results: The average age of the pregnant women was 28.8±6.4 years and ultrasonographic gestational age was 31.9±2.6 weeks. Apgar scores at 1st minute were affected significantly by fetal body weight (p=0.001), gestational age (p=0.001), height (p=0.004) and head circumference (p=0.011). None of these variables exhibited a noteworthy effect on Apgar scores at 5th minute. Conclusion: Efforts must be made to achieve advancement of gestational age until delivery in the follow-up preterm of twins. A well-established algorithm with special emphasis to risk factors is necessary to standardize and popularize the appropriate management strategy. PMID:27648040

    Purpose Laparoscopic subtotal cholecystectomy (LSC) can be an alternative surgical technique for difficult cholecystectomies. Surgeons performing LSC sometimes leave the posterior wall of the gallbladder (GB) to shorten the operation time and avoid liver injury. However, leaving the inflamed posterior GB wall is a major concern. In this study, we evaluated the clinical outcomes of standard laparoscopic cholecystectomy (SLC), LSC, and LSC removing only anterior wall of the GB (LSCA). Methods We retrospectively reviewed the medical records of laparoscopic cholecystectomies performed between January 2006 to December 2015 and analyzed the outcomes of SLC, LSC, and LSCA. Results A total of 1,037 patients underwent SLC. 22 patients underwent LSC; and 27 patients underwent LSCA. The mean operating times of SLC, LSC, and LSCA were 41, 74, and 68 minutes, respectively (P < 0.01). Blood loss was 5, 45, and 33 mL (P < 0.05). The mean lengths of postoperative hospitalization were 3.4, 5.4, and 5.8 days. Complications occurred in 24 SLC patients (2.3%), 2 LSC patients (9%), and 1 LSCA patient (3.7%). There was no mortality among the LSC and LSCA patients. Conclusion LSC and LSCA are safe and feasible alternatives for difficult cholecystectomies. These procedures help surgeons avoid bile duct injury and conversion to laparotomy. LSCA has the benefits of shorter operation time and less bleeding compared to LSC. PMID:27847794

    Evaluation of clinical genetics services (CGS), including genetic counseling and genetic testing, has been problematic. Patient mortality and morbidity are unlikely to be directly improved by interventions offered in CGS. Patient-reported outcomes (PROs) are not routinely measured in CGS evaluation, but this may change as patient-reported outcome measures (PROMs) become a key part of how healthcare services are managed and funded across the world. However, there is no clear consensus about which PROMs are most useful for CGS evaluation. This review summarizes the published research on how PROs from CGS have been measured and how patients may benefit from using those services, with a focus on patient empowerment. Many patient benefits (PROs) identified repeatedly in the research literature can be re-interpreted within a patient empowerment framework. Other important PROs identified include family functioning, social functioning, altruism, sense of purpose, enabling development of future research and treatment/participating in research. Well-validated measures are available to capture (dimensions of) patient empowerment. Although generic measures of family functioning are available, suitable measures capturing social functioning, development of future treatments, and altruism were not identified in this review. Patient empowerment provides one useful approach to measuring PROs from CGS.

    We report our clinical experience using the modified Cadenat method to treat acromioclavicular joint dislocation, and discuss the usefulness of this method. This study examined 6 shoulders in 6 patients (5 males, 1 female) who were diagnosed with acromioclavicular joint dislocation and treated with the modified Cadenat method at our hospital. Average age at onset was 49.3 years (26-78 years), average time interval from injury until surgery was 263.8 days (10 to 1100 days), and the average follow-up period was 21.7 months (12 to 42 months). Post-operative assessment was performed using plain radiographs to determine shoulder joint dislocation rate and Japanese Orthopaedic Association (JOA) score. The average post-operative JOA score was 94.1 points (91 to 100 points). The acromioclavicular joint dislocation rate improved from 148.7% (72 to 236%) before surgery to 28.6% (0 to 60%) after surgery. Conservative treatment has been reported to achieve good outcomes in acromioclavicular joint dislocations. However, many patients also experience chronic pain or a sensation of fatigue upon putting the extremity in an elevated posture, and therefore ensuring the stability of the acromioclavicular joint is crucial for highly active patients. In this study, we treated acromioclavicular joint dislocations by the modified Cadenat method, and were able to achieve favorable outcomes.

    The aims of the study were to determine the prevalence of variations in the recorded outcomes of clinical evaluations by 2 different physicians during a single patient visit and to comment on observations of physician practices regarding history taking and physical examination. Structured interviews were conducted with both junior and supervising physicians after they had evaluated patients in a pediatric emergency department who presented with complaints of fever (temperature, >100.4°F) in infants younger than 3 months, fever (temperature, >102.2°F) in infants aged 3 to 12 months, headache in patients older than 5 years, abdominal pain in patients older than 5 years, and head injury in patients younger than 18 years. Data were analyzed with descriptive statistics. Most of the data reported by both junior and supervising physicians showed response disagreement. The questions on fever (temperature, >102.2°F) in infants aged 3 to 12 months showed 29% (10/34) disagreement on fever duration and 45% (5/11) on fever height. Questions on abdominal pain in children older than 5 years showed 24% (24/100) disagreement on reporting right lower quadrant pain and 10% (11/106) on right lower quadrant tenderness on examination; however, the discrepancy rates were 56% (56/100) when considering less than complete agreement on all painful sites and 53% (56/106) on all tender sites. Supervising physicians questioned and examined patients presenting with abdominal pain more often than those presenting with other complaints. There are significant variations in the recorded outcome of clinical evaluations by 2 different physicians during a single patient visit. Supervising physicians are more cautious to question and examine patients presenting with abdominal pain compared with other chief complaints.

    Colorectal cancer remains the second leading cause of cancer-related deaths among US men and women. Screening rates have been slow to increase, and disparities in screening remain. To address the disparity in screening for this high burden but largely preventable disease, the Centers for Disease Control and Prevention (CDC) designed and established a 4-year Colorectal Cancer Screening Demonstration Program (CRCSDP) in 2005 for low-income, under-insured or uninsured men and women aged 50 to 64 years in 5 participating US program sites. In this report, the authors describe the design of the CRCSDP and the overall clinical findings and screening test performance characteristics, including the positive fecal occult blood testing (FOBT) rate; the rates of polyp, adenoma, and cancer detection with FOBTs and colonoscopies; and the positive predicative value for polyps, adenomas, and cancers. In total, 5233 individuals at average risk and increased risk were screened for colorectal cancer across all 5 sites, including 44% who underwent screening FOBT and 56% who underwent screening colonoscopy. Overall, 77% of all individuals screened were women. The FOBT positivity rate was 10%. Results from all screening or diagnostic colonoscopies indicated that 75% had negative results and required a repeat screening colonoscopy in 10 years, 16% had low-risk adenomas and required surveillance colonoscopy in 5 to 10 years, 8% had high-risk adenomas and required surveillance colonoscopy in 3 years, and 0.6% had invasive cancers. This report documents the successes and challenges in implementing the CDC's CRCSDP and describes the clinical outcomes of this 4-year initiative, the patterns in program uptake and test choice, and the comparative test performance characteristics of FOBT versus colonoscopy. Patterns in final outcomes from the follow-up of positive screening tests were consistent with national registry data. © 2013 American Cancer Society.

    Abstract Pasteurella multocida, a zoonotic infectious organism, has most often been described in patients after an animal bite. Here, we characterize the clinical features and outcomes of P multocida infection in a large cohort of patients according to the presence or absence of an animal bite. We retrospectively searched MUSC's laboratory information system for all patients with positive P multocida cultures from 2000 to 2014. Extensive data were abstracted, including clinical and outcome data. The Charlson comorbidity index (CCI) was used to assess comorbidities among patients. We identified 44 patients with P multocida infections, including 25 with an animal bite. The average age was 64 years and the majority of patients were women (N = 30). There was no difference in age and sex distribution among those with and without a bite (P = 0.38 and 0.75, respectively). A CCI ≥1 was significantly associated with the absence of a bite (P = 0.006). Patients presenting without a bite were more frequently bacteremic (37% vs 4%, respectively, P = 0.001), and were hospitalized more often (84% vs 44%, respectively, P = 0.012). Of the 8 patients who required intensive care unit (ICU)-based care, 7 were non-bite-related. There were 4 deaths, all occurring in patients not bitten. P multocida infections not associated with an animal bite were often associated with bacteremia, severe comorbidity(ies), immune-incompetent states, the need for ICU management, and were associated with substantial mortality.

    Successful lung transplantation for patients with pulmonary fibrosis from telomerase mutations may be limited by systemic complications of telomerase dysfunction, including myelosuppression, cirrhosis, and malignancy. We describe clinical outcomes in 14 lung transplant recipients with telomerase mutations. Subjects underwent lung transplantation between February 2005 and April 2014 at 5 transplant centers. Data were abstracted from medical records, focusing on outcomes reflecting post-transplant treatment effects likely to be complicated by telomerase mutations. The median age of subjects was 60.5 years (interquartile range = 52.0-62.0), 64.3% were male, and the mean post-transplant observation time was 3.2 years (SD ± 2.9). A mutation in telomerase reverse transcriptase was present in 11 subjects, a telomerase RNA component mutation was present in 2 subjects, and an uncharacterized mutation was present in 1 subject. After lung transplantation, 10 subjects were leukopenic and 5 did not tolerate lymphocyte anti-proliferative agents. Six subjects developed recurrent lower respiratory tract infections, 7 developed acute cellular rejection (A1), and 4 developed chronic lung allograft dysfunction. Eight subjects developed at least 1 episode of acute renal failure and 10 developed chronic renal insufficiency. In addition, 3 subjects developed cancer. No subjects had cirrhosis. At data censorship, 13 subjects were alive. The clinical course for lung transplant recipients with telomerase mutations is complicated by renal disease, leukopenia with intolerance of lymphocyte anti-proliferative agents, and recurrent lower respiratory tract infections. In contrast, cirrhosis was absent, acute cellular rejection was mild, and development of chronic lung allograft dysfunction was comparable to other lung transplant recipients. Although it poses challenges, lung transplantation may be feasible for patients with pulmonary fibrosis from telomerase mutations. Copyright © 2015

    Background Successful lung transplantation (LT) for patients with pulmonary fibrosis from telomerase mutations is limited by systemic complications of telomerase dysfunction including myelosuppression, cirrhosis, and malignancy. We describe clinical outcomes among 14 LT recipients with telomerase mutations. Methods Subjects underwent LT between February 2005 and April 2014 at 5 LT centers. We abstracted data from medical records, focusing on outcomes reflecting post-LT treatment effects likely to be complicated by telomerase mutations. Results The median age of subjects was 60.5 years (IQR 52.0–62.0), 64.3% were male, and the mean post-LT observation time was 3.2 years (SD ±2.9). Eleven subjects had a mutation in telomerase reverse transcriptase, 2 in telomerase RNA component, and 1 had an uncharacterized mutation. Ten subjects were leukopenic post-LT; leukopenia prompted cessation of mycophenolate mofetil in 5 and treatment with filgrastim in 4. Six subjects had recurrent lower respiratory tract infections (LRTI), 7 had acute cellular rejection (ACR) (A1), and 4 developed chronic lung allograft dysfunction (CLAD). Ten LT recipients developed chronic renal insufficiency and 8 experienced acute, reversible renal failure. Three developed cancer, none had cirrhosis. Thirteen subjects were alive at data censorship. Conclusions The clinical course for LT recipients with telomerase mutations is complicated by renal disease, leukopenia prompting a change in the immunosuppressive regimen, and recurrent LTRI. In contrast, cirrhosis was absent, ACR was mild, and development of CLAD was comparable to other LT populations. While posing challenges, lung transplantation may be feasible for patients with pulmonary fibrosis due to telomerase mutations. PMID:26169663

  20. Different Placebos, Different Mechanisms, Different Outcomes: Lessons for Clinical Trials.

    Clinical trials use placebos with the assumption that they are inert, thus all placebos are considered to be equal. Here we show that this assumption is wrong and that different placebo procedures are associated to different therapeutic rituals which, in turn, trigger different mechanisms and produce different therapeutic outcomes. We studied high altitude, or hypobaric hypoxia, headache, in which two different placebos were administered. The first was placebo oxygen inhaled through a mask, whereas the second was placebo aspirin swallowed with a pill. Both placebos were given after a conditioning procedure, whereby either real oxygen or real aspirin was administered for three consecutive sessions to reduce headache pain. We found that after real oxygen conditioning, placebo oxygen induced pain relief along with a reduction in ventilation, blood alkalosis and salivary prostaglandin (PG)E2, yet without any increase in blood oxygen saturation (SO2). By contrast, after real aspirin conditioning, placebo aspirin induced pain relief through the inhibition of all the products of cyclooxygenase, that is, PGD2, PGE2, PGF2, PGI2, thromboxane (TX)A2, without affecting ventilation and blood alkalosis. Therefore, two different placebos, associated to two different therapeutic rituals, used two different pathways to reduce headache pain. The analgesic effect following placebo oxygen was superior to placebo aspirin. These findings show that different placebos may use different mechanisms to reduce high altitude headache, depending on the therapeutic ritual and the route of administration. In clinical trials, placebos and outcome measures should be selected very carefully in order not to incur in wrong interpretations.

    To determine the survival rate and marginal bone loss (MBL) of zirconia dental implants restored with single crowns or fixed dental prostheses. An electronic search was conducted up to November 2015 (without any restriction regarding the publication time) through the databases MEDLINE (PubMed), Cochrane Library, and EMBASE to identify randomized controlled clinical trials and prospective clinical trials including >15 patients. Primary outcomes were survival rate and MBL. Furthermore, the influence of several covariates on MBL was evaluated. Qualitative assessment and statistical analyses were performed. This review was conducted according to preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines for systematic reviews. With the applied search strategy, 4,196 titles could be identified. After a screening procedure, 2 randomized controlled clinical trials and 7 prospective clinical trials remained for analyses. In these trials, a total of 326 patients received 398 implants. The follow-up ranged from 12 to 60 mo. Implant loss was mostly reported within the first year, especially within the healing period. Thereafter, nearly constant survival curves could be observed. Therefore, separate meta-analyses were performed for the first and subsequent years, resulting in an implant survival rate of 95.6% (95% confidence interval: 93.3% to 97.9%) after 12 mo and, thereafter, an expected decrease of 0.05% per year (0.25% after 5 y). Additionally, a meta-analysis was conducted for the mean MBL after 12 mo, resulting in 0.79 mm (95% confidence interval: 0.73 to 0.86 mm). Implant bulk material and design, restoration type, and the application of minor augmentation procedures during surgery, as well as the modes of temporization and loading, had no statistically significant influence on MBL. The short-term cumulative survival rates and the MBL of zirconia implants in the presented systematic review are promising. However, additional data are still

    Purpose Previous research has demonstrated relationships of social support with disease-related biomarkers in patients with ovarian cancer. However, the clinical relevance of these findings to patient outcomes has not been established. This prospective study examined how social support relates to long-term survival among consecutive patients with ovarian cancer. We focused on two types of social support: social attachment, a type of emotional social support reflecting connections with others, and instrumental social support reflecting the availability of tangible assistance. Patients and Methods Patients were prospectively recruited during a presurgical clinic visit and completed surveys before surgery. One hundred sixty-eight patients with histologically confirmed epithelial ovarian cancer were observed from the date of surgery until death or December 2010. Clinical information was obtained from medical records. Results In a Cox regression model, adjusting for disease stage, grade, histology, residual disease, and age, greater social attachment was associated with a lower likelihood of death (hazard ratio [HR], 0.87; 95% CI, 0.77 to 0.98; P = .018). The median survival time for patients with low social attachment categorized on a median split of 15 was 3.35 years (95% CI, 2.56 to 4.15 years). In contrast, by study completion, 59% of patients with high social attachment were still alive after 4.70 years. No significant association was found between instrumental social support and survival, even after adjustment for covariates. Conclusion Social attachment is associated with a survival advantage for patients with ovarian cancer. Clinical implications include the importance of screening for deficits in the social environment and consideration of support activities during adjuvant treatment. PMID:22802321

    This study aimed to investigate retrospectively the outcome of surgical periodontal therapy. Periodontal surgeries implemented at General Dentistry, Tokyo Dental College Suidobashi Hospital during the period of April 2010 through March 2012 were subjected to data analysis. After initial periodontal therapy, 17 clinicians performed a total of 138 periodontal surgeries in 80 patients with moderate to advanced periodontitis (31 men and 49 women; mean age 54). Cases (sites) operated were as follows: open flap debridement=102, periodontal regenerative therapy=29 (17 for intrabony defects, 12 for furcation involvements) and periodontal plastic surgery=7. Enamel matrix derivative or bone graft was used for regenerative therapy. Clinical data were analyzed focusing on the comparison between open flap debridement and regenerative therapy. At 5 months after open flap debridement, mean reduction in probing depth (PD) and gain in clinical attachment level (CAL) was 3.9 mm (range -1.0-9.0) and 2.3 mm (range -1.0-9.0), respectively. The corresponding values with regenerative therapy were 4.0 mm (range 0-8.0) and 2.8 mm (-1.0-6.0), respectively. At sites with initial PD≥8 mm, a significantly greater gain in CAL was obtained with the regenerative therapy than with flap surgery (mean CAL gain 4.3 mm vs. 2.9 mm, p<0.05). Periodontal surgery performed in our clinical setting demonstrated a favorable short-term outcome. Our data suggest the efficacy of regenerative therapy, in particular for the treatment of deep pockets.

    Pemphigus vulgaris (PV) is a rare, potentially fatal chronic autoimmune disease of the skin and mucous membrane. The objective of this study was to analyze the clinical outcomes and side effects associated with treatment of childhood PV (CPV). A retrospective review of the English language literature was conducted through PUBMED using the words childhood pemphigus vulgaris, and treatment or clinical outcome. Only patients under 12 years of age were included. Thirty-three cases were found in 29 reports. Mean age at onset was 8.3 years (range 1.5-12 yrs). Mucosal involvement (97.0%) was more common than cutaneous involvement (84.8%). Oral mucosa was the most common site of mucosal involvement (93.9%), followed by genital (20.6%), ocular (11.8%), and nasal mucosa (2.9%). Mean duration of therapy was 4.5 years (range 0.6-14.5 yrs), and mean duration of follow-up was 5.2 years (range 0.6-16 yrs). Complete recovery with no further therapy was achieved in 18.2% and partial recovery with minor relapses while on maintenance therapy in 78.8%. One patient died due to infection (3.0%). Serious side effects were present in 60.6%. The most common were cushingoid features (65.0%), growth retardation (50.0%), and infection (50.0%). Two patients who were refractory to systemic corticosteroids and immunosuppressive agents (ISA) had a favorable clinical response to Rituximab. Current therapy for CPV involving the use of long-term systemic corticosteroids in conjunction with ISA results in prolonged immunosuppression, causing systemic infections and growth retardation. Safer and more effective therapies need to be explored.

    To examine characteristics and outcomes of type 2 diabetes (T2DM) patients prescribed canagliflozin (CANA) and managed in the real-world setting of a diabetes clinic. Primary outcome was change in A1c, and secondary outcomes were change in weight and blood pressure. Study was an electronic health record (EHR) review of CANA prescribed at the diabetes clinic from June 2013 to June 2015. Patients were included in the study if they were adults with T2DM, received routine follow-up diabetes care at the diabetes clinic, received an initial prescription for CANA from a diabetes clinic prescriber, and returned for at least one follow-up office visit (OV) after initial CANA prescribing. Paired t-tests were performed on the primary and secondary outcomes, and p < .05 was considered statistically significant. Descriptive statistics were used to characterize the population and other outcomes. A total of 462 patients met study inclusion criteria. Mean baseline values were: age 55.32 years, BMI 38.23 kg/m(2), A1c 8.84%, mean number of diabetes medications (including CANA) 3.58. Men comprised 60% of patients. At baseline, 54% of patients were prescribed insulin. A1c decreased by 1.06% and 1.09% (p < .0001), weight decreased by 2.01% and 1.83% (p < .001), systolic blood pressure (SBP) decreased by 3.2% and 2.4% (p < .0001), and diastolic blood pressure (DBP) decreased by 2.59% and 2.16% (p = .0002) from baseline to first and second follow-up OV, respectively. Study limitations included retrospective design, inability to control for confounding factors (e.g. changes in nutrition, exercise, medical care plan, medications), missing information in the EHR, potential lack of generalizability of results to those in a non-specialty diabetes clinic, inability to assess adherence, and inability to assess reliable adverse event data. ANA was associated with a statistically and clinically significant reduction in A1c, weight, and blood pressure when added to multiple

    We sought to determine whether Alberta Stroke Program Early CT Scores (ASPECTS) derived from baseline noncontrast CT (NCCT) and perfusion CT (CTP) imaging maps can predict clinical outcome after recanalization therapy in acute ischemic stroke of the middle cerebral artery (MCA) territory and whether changes in the ASPECTS from baseline to 24 h after recanalization therapy can help predict clinical outcome. We retrospectively studied consecutive patients with acute ischemic stroke of the MCA territory treated with intravenous tissue plasminogen activator (t-PA) or abciximab within 6 h of symptom onset. We performed NCCT and CTP before and 24 h after intravenous t-PA or abciximab treatment and determined the ASPECTS and the changes in the ASPECTS from baseline to 24 h. A favorable outcome was defined as a modified Rankin scale score of 0 or 1 at 3 months. During the 18-month study period 44 patients were studied. In multivariate logistic regression analysis, the cerebral blood volume (CBV) ASPECTS (OR 1.80, 95% CI 1.10 to 2.93) at baseline and the increase in cerebral blood flow (CBF) ASPECTS (OR 1.68, 95% CI 1.13 to 2.50) from baseline to 24 h were associated with a favorable outcome. The cutoff values for a favorable outcome using receiver operating characteristic curves were 8 and 1, respectively. When the CBV ASPECTS at baseline was 8 or more, its positive predictive value was only 58.1%. When the CBV ASPECTS at baseline was 8 or more and the increase in CBF ASPECTS from baseline to 24 h was 1 or more, the positive predictive value was 100% and the negative predictive value was 74.2%. The CBV ASPECTS derived from baseline CTP maps was found to be predictive of a favorable outcome, but its positive predictive value was suboptimal. The change in the CBF ASPECTS from baseline to 24 h after treatment was helpful in predicting outcome.

    The whole spectrum of chromosomal abnormalities and their prognostic significance in children and adolescents with acute myeloid leukemia (AML) has not been fully elucidated yet, although a considerable amount of knowledge has been gained recently. Moreover, the incidence and prognostic impact of monosomal karyotypes (MKs), which are new cytogenetic categories reported recently in adults with AML, are currently unknown for childhood and adolescent AML. In this study, we investigated the cytogenetic and clinical characteristics of 140 children and adolescents (≤21 y) with AML, and correlated their cytogenetic features with both the clinical characteristics and outcomes of our patient cohort. The most frequent cytogenetic abnormality found in our study was the t(15;17), followed by the t(8;21). Striking differences in the genetic abnormalities and French-American-British subtypes were found among infants, children, and adolescents. Of 124 cases, 15 (12.1%) met the criteria of the MK definition, and 12 of the 15 MKs (80%) were complex karyotypes. Of 124 cases, 27 (21.8%) had cytogenetic abnormalities sufficient to be diagnosed as AML with myelodyspastic sydrome-related features. As expected, patients with the t(15;17) had the most favorable outcomes, whereas patients with 11q23 rearrangements and monosomy 7 had the worst outcomes. These data expand our knowledge by providing novel insights into the cytogenetic features and their correlations with clinical characteristics and outcomes in childhood and adolescent AML.

    Strokes secondary to acute internal carotid artery (ICA) occlusion are associated with extremely poor prognosis. The best treatment approach to acute stroke in this setting is unknown. We sought to determine clinical outcomes in patients with acute ischemic stroke attributable to ICA occlusion treated with intravenous (IV) systemic thrombolysis or intra-arterial endovascular therapy. Using the PubMed database, we searched for studies that included patients with acute ischemic stroke attributable to ICA occlusion who received treatment with IV thrombolysis or intra-arterial endovascular interventions. Studies providing data on functional outcomes beyond 30 days and mortality and symptomatic intracerebral hemorrhage (sICH) rates were included in our analysis. We compared the proportions of patients with favorable functional outcomes, sICH, and mortality rates in the 2 treatment groups by calculating χ(2) and confidence intervals for odds ratios. We identified 28 studies with 385 patients in the IV thrombolysis group and 584 in the endovascular group. Rates of favorable outcomes and sICH were significantly higher in the endovascular group than the IV thrombolysis-only group (33.6% vs 24.9%, P=0.004 and 11.1% vs 4.9%, P=0.001, respectively). No significant difference in mortality rate was found between the groups (27.3% in the IV thrombolysis group vs 32.0% in the endovascular group; P=0.12). According to our systematic review, endovascular treatment of acute ICA occlusion results in improved clinical outcomes. A higher rate of sICH after endovascular treatment does not result in increased overall mortality rate.

    Ebola virus disease is caused by a highly contagious and pathogenic threadlike RNA virus of the Filoviridae family. The index human case is usually a zoonosis that launches human-to-human transmission interface with varying levels of sustainability of the epidemic depending on the level of public health preparedness of the affected country and the Ebola virus strain. The disease affects all age groups in the population. Clinical diagnosis is challenging in index cases especially in the early stages of the disease when the presenting features are usually nonspecific and only similar to a flu-like illness. However, in the agonal stages, hemorrhage frequently occurs in a high proportion of cases. The diagnostic gold standard is by detecting the antigen using reverse transcription-polymerase chain reaction. Mortality rates in the past 28 outbreaks since 1976 have ranged from 30% to 100% in different settings among adults, but lower mortality rates have been documented in children. This review aims to describe Ebola virus infection, clinical presentation, diagnosis and outcomes in children.

    This retrospective study aimed to describe the clinical presentations, possible causes, and outcomes of children with idiopathic intracranial hypertension who presented to the authors' clinic. The mean age at onset of symptoms in the authors' cohort of 19 children was 6 years (range: 7 months to 12 years). Most patients (90%) were under 11 years old and (84.2%) symptomatic. The probable cause was identified in 7/19 (37.0%) patients. The most common cause was vitamin D deficiency (26.3%). Other associated probably coincidental comorbidities included sinusitis (5/19, 26.3%), hypophosphatasia (1/19), Pyle disease (1/19), and measles vaccine (1/19). Apart from 2 patients who required lumboperitoneal shunt, the cerebrospinal fluid pressure returned to normal in all patients within a period of 6 weeks to 1 year (average, 5 months). Of those who followed up with the authors' ophthalmologist, 30.7% developed optic atrophy or pallor; 75% of these patients had previous ocular comorbidities.

    Advances in flow cytometry and other single-cell technologies have enabled high-dimensional, high-throughput measurements of individual cells as well as the interrogation of cell population heterogeneity. However, in many instances, computational tools to analyze the wealth of data generated by these technologies are lacking. Here, we present a computational framework for unbiased combinatorial polyfunctionality analysis of antigen-specific T-cell subsets (COMPASS). COMPASS uses a Bayesian hierarchical framework to model all observed cell subsets and select those most likely to have antigen-specific responses. Cell-subset responses are quantified by posterior probabilities, and human subject-level responses are quantified by two summary statistics that describe the quality of an individual's polyfunctional response and can be correlated directly with clinical outcome. Using three clinical data sets of cytokine production, we demonstrate how COMPASS improves characterization of antigen-specific T cells and reveals cellular 'correlates of protection/immunity' in the RV144 HIV vaccine efficacy trial that are missed by other methods. COMPASS is available as open-source software.

    This study was designed to describe the characteristics and clinical outcome of patients diagnosed with plantar vein thrombosis. Patients presenting with sudden pain and/or swelling of the foot were evaluated by duplex scanning of the affected leg. All the main foot veins were imaged with high resolution multi-linear array transducers. The location and extent of thrombosis was recorded in detail. All patients were scheduled for clinical and ultrasound follow-up within a week from the diagnosis and at various intervals thereafter. Acute thrombosis was found in the plantar veins in 11 patients of whom 7 were females. Pain was presented in all patients, swelling in 8 and the left foot was involved in 7. From the risk factors evaluated, the most common were recent surgery 4, use of contraceptive pills 3, followed by malignancy, airplane travel, HIV-AIDS infection, and past history of DVT in one each. Plantar veins were exclusively affected in 8, with lower segment of the posterior tibial veins in 2 and the great saphenous vein in 1. In the follow up, there was evidence of thrombosis extension in 3 patients. At six months partial recanalization was found in 9 and complete in 2. Pain and swelling of the foot can be caused by plantar vein thrombosis. Complete or partial recanalization occurs in these patients by 6 months. Thrombi in the plantar veins can progress more proximally with the possibility of postthrombotic events.

    moderate degrees of cortical atrophy, PVL, and DWML had no effect on clinical outcome. Patients with status cribriformis and those with lacunes tended to show comparatively less improvement in the UPDRS ADL off score (p = 0.014 and p = 0.016, respectively) at 6 months. This tendency was also present in patients with status cribriformis 1 year postoperatively (p = 0.046). Patients with both status cribriformis and lacunes had a higher incidence of transient altered mental status immediately postoperatively (p = 0.05). Mild-to-moderate degrees of cortical atrophy, ventriculomegaly, and ischemic encephalopathy do not predispose patients to less favorable outcomes following unilateral pallidotomy. Patients with both status cribriformis and lacunes have a higher risk of transient side effects; however, with regard to clinical outcome, these patients should not be denied surgical treatment.

    Velopharyngeal insufficiency affects as many as one in three patients after cleft palate repair. Correction using a posterior pharyngeal flap (PPF) has been shown to improve clinical speech symptomatology; however, PPFs can be complicated by hyponasality and obstructive sleep apnea. The goal of this study was to assess if speech outcomes revert after clinically indicated PPF takedown. The cleft-craniofacial database of the Children's Hospital of Pittsburgh at the University of Pittsburgh Medical Center was retrospectively queried to identify patients with a diagnosis of velopharyngeal insufficiency treated with PPF who ultimately required takedown. Using the Pittsburgh Weighted Speech Score (PWSS), preoperative scores were compared to those after PPF takedown. Outcomes after 2 different methods of PPF takedown (PPF takedown alone or PPF takedown with conversion to Furlow palatoplasty) were stratified and cross-compared. A total of 64 patients underwent takedown of their PPF. Of these, 18 patients underwent PPF takedown alone, and 46 patients underwent PPF takedown with conversion to Furlow Palatoplasty. Patients averaged 12.43 (range, 3.0-22.0)(SD: 3.93) years of age at the time of PPF takedown, and 58% were men. Demographics between groups were not statistically different. The mean duration of follow-up after surgery was 38.09 (range, 1-104) (SD, 27.81) months. For patients undergoing PPF takedown alone, the mean preoperative and postoperative PWSS was 3.83 (range, 0.0-23.0) (SD, 6.13) and 4.11 (range, 0.0-23.0) (SD, 5.31), respectively (P = 0.89). The mean change in PWSS was 0.28 (range, -9.0 to 7.0) (SD, 4.3). For patients undergoing takedown of PPF with conversion to Furlow palatoplasty, the mean preoperative and postoperative PWSS was 6.37 (range, 0-26) (SD, 6.70) and 3.11 (range, 0.0-27.0) (SD, 4.14), respectively (P < 0.01). The mean change in PWSS was -3.26 (range, -23.0 to 4.0) (SD, 4.3). For all patients, the mean preoperative PWSS was 5.66 (range, 0

    Objective The incidence, clinical characteristics and outcomes of critically-ill, non-intubated patients with evidence of the acute respiratory distress syndrome (ARDS) remain inadequately characterized. Design Secondary analysis of a prospective observational cohort study. Setting Vanderbilt University Medical Center. Patients Among adult patients enrolled in a large, multi-intensive care unit prospective cohort study between the years of 2006 and 2011, we studied intubated and non-intubated patients with ARDS as defined by acute hypoxemia (PaO2/FiO2 ≤ 300 or SpO2/FiO2 ≤ 315) and bilateral radiographic opacities not explained by cardiac failure. We excluded patients not committed to full respiratory support. Interventions None. Measurements and Main Results Of 457 patients with ARDS, 106 (23%) were not intubated at the time of meeting all other ARDS criteria. Non-intubated patients had lower morbidity and severity of illness compared to intubated patients; however, mortality at 60 days was the same (36%) in both groups (P=0.91). Of the 106 non-intubated patients, 36 (34%) required intubation within the subsequent 3 days of follow-up; this “late” intubation subgroup had significantly higher 60-day mortality (56%) compared to both the “early” intubation group (36%, P<0.03) and to patients never requiring intubation (26%, P=0.002). Increased mortality in the “late” intubation group persisted at 2 years follow-up. Adjustment for baseline clinical and demographic differences did not change the results. Conclusions A substantial proportion of critically ill adults with ARDS were not intubated in their initial days of intensive care, and many were never intubated. Late intubation was associated with increased mortality. Criteria defining ARDS prior to need for positive pressure ventilation are needed so that these patients can be enrolled in clinical trials and to facilitate early recognition and treatment of ARDS.

A total of 171 patients with orbital cysticercosis. Retrospective case series involving consecutive patients with orbital cysticercosis from March 1990 to December 2001. Clinical resolution and significant residual deficit. The median age at presentation was 13 years (range 2-65 years), and 93 patients (54.4%) were male. The 3 main symptoms at presentation were periocular swelling (38%), proptosis (24%), and ptosis (14%) with a median duration of 2 (range 0-24) months. The 3 main signs at presentation included ocular motility restriction (64.3%), proptosis (44.4%), and diplopia (36.8%). The cyst locations in the decreasing order of frequency were anterior orbit (69%), subconjunctival space (24.6%), posterior orbit (5.8%), and the eyelid (0.6%). In all, 80.7% of patients had cysts in relation to an extraocular muscle. The superior rectus (33.3%) was the most commonly involved extraocular muscle. Contact B-scan ultrasonography was diagnostic of cysticercosis in 84.4% of patients. Orbital cysticercosis was managed medically in 158 of 166 patients. Although 149 patients received a combination of oral albendazole and prednisolone, 1 patient received oral albendazole alone, 7 patients received oral prednisolone alone, and 1 patient received oral praziquantel. Surgery was performed in 8 patients. Clinical resolution was seen in 128 of 138 patients (92.8%) at 1 month and 81 of 85 patients (95.3%) at 3 months. A significant residual deficit was present in 29 of 138 patients (21.0%) at the final follow-up and included proptosis in 7 patients, ptosis in 6 patients, ocular motility restriction in 3 patients, diplopia in 2 patients, strabismus in 2 patients, and a combination of the above in 9 patients.

    Purpose: To report preliminary clinical outcomes for pediatric patients treated with proton beam radiation for intracranial ependymoma and compare the dose distributions of intensity-modulated radiation therapy with photons (IMRT), three-dimensional conformal proton radiation, and intensity-modulated proton radiation therapy (IMPT) for representative patients. Methods and Materials: All children with intracranial ependymoma confined to the supratentorial or infratentorial brain treated at the Francis H. Burr Proton Facility and Harvard Cyclotron between November 2000 and March 2006 were included in this study. Seventeen patients were treated with protons. Proton, IMRT, and IMPT plans were generated with similar clinical constraints for representative infratentorial and supratentorial ependymoma cases. Tumor and normal tissue dose-volume histograms were calculated and compared. Results: At a median follow-up of 26 months from the start date of radiation therapy, local control, progression-free survival, and overall survival rates were 86%, 80%, and 89%, respectively. Subtotal resection was significantly associated with decreased local control (p = 0.016). Similar tumor volume coverage was achieved with IMPT, proton therapy, and IMRT. Substantial normal tissue sparing was seen with proton therapy compared with IMRT. Use of IMPT will allow for additional sparing of some critical structures. Conclusions: Preliminary disease control with proton therapy compares favorably with the literature. Dosimetric comparisons show the advantage of proton radiation compared with IMRT in the treatment of ependymoma. Further sparing of normal structures appears possible with IMPT. Superior dose distributions were accomplished with fewer beam angles with the use of protons and IMPT.

    Klotho functions as a tumor suppressor predominantly expressed in renal tubular cells, the origin of clear cell renal cell carcinoma (ccRCC). Altered expression and/or activity of growth factor receptor have been implicated in ccRCC development. Although Klotho suppresses a tumor progression through growth factor receptor signaling including insulin-like growth factor-1 receptor (IGF-1R), the role of Klotho acting on IGF-1R in ccRCC and its clinical relevance remains obscure. Here, we show that Klotho is favorable prognostic factor for ccRCC and exerts tumor suppressive role for ccRCC through inhibiting IGF-1R signaling. Our data shows the following key findings. First, in tumor tissues, the level of Klotho and IGF-1R expression are low or high, respectively, compared to that of adjacent non-neoplastic parenchyma. Second, the Klotho expression is clearly low in higher grade of ccRCC and is closely associated with clinical outcomes in tumor progression. Third, Klotho suppresses IGF-1-stimulated cell proliferation and migration by inhibiting PI3K/Akt pathway. These results provide compelling evidence supporting that Klotho acting on IGF-1R signaling functions as tumor suppressor in ccRCC and suggest that Klotho is a potential carcinostatis substance for ccRCC.

    Platelet-derived growth factor (PDGF) gene therapy offers promise for tissue engineering of tooth-supporting alveolar bone defects. To date, limited information exists regarding the safety profile and systemic biodistribution of PDGF gene therapy vectors when delivered locally to periodontal osseous defects. The aim of this preclinical study was to determine the safety profile of adenovirus encoding the PDGF-B gene (AdPDGF-B) delivered in a collagen matrix to periodontal lesions. Standardized alveolar bone defects were created in rats, followed by delivery of matrix alone or containing AdPDGF-B at 5.5 x 10(8) or 5.5 x 10(9) plaque-forming units/ml. The regenerative response was confirmed histologically. Gross clinical observations, hematology, and blood chemistries were monitored to evaluate systemic involvement. Bioluminescence and quantitative polymerase chain reaction were used to assess vector biodistribution. No significant histopathological changes were noted during the investigation. Minor alterations in specific hematological and blood chemistries were seen; however, most parameters were within the normal range for all groups. Bioluminescence analysis revealed vector distribution at the axillary lymph nodes during the first 2 weeks with subsequent return to baseline levels. AdPDGF-B was well contained within the localized osseous defect area without viremia or distant organ involvement. These results indicate that AdPDGF-B delivered in a collagen matrix exhibits acceptable safety profiles for possible use in human clinical studies.

    Clinical quality registries (CQRs) are playing an increasingly important role in improving health outcomes and reducing health care costs. CQRs are established with the purpose of monitoring quality of care, providing feedback, benchmarking performance, describing pattern of treatment, reducing variation and as a tool for conducting research. To synthesise the impact of clinical quality registries (CQRs) as an 'intervention' on (I) mortality/survival; (II) measures of outcome that reflect a process or outcome of health care; (III) health care utilisation; and (IV) healthcare-related costs. The following electronic databases were searched: MEDLINE, EMBASE, CENTRAL, CINAHL and Google Scholar. In addition, a review of the grey literature and a reference check of citations and reference lists within articles was undertaken to identify relevant studies in English covering the period January 1980 to December 2016. The PRISMA-P methodology, checklist and standard search strategy using pre-defined inclusion and exclusion criteria and structured data extraction tools were used. Data on study design and methods, participant characteristics attributes of included registries and impact of the registry on outcome measures and/or processes of care were extracted. We identified 30102 abstracts from which 75 full text articles were assessed and finally 17 articles were selected for synthesis. Out of 17 studies, six focused on diabetes care, two on cardiac diseases, two on lung diseases and others on organ transplantations, rheumatoid arthritis, ulcer healing, surgical complications and kidney disease. The majority of studies were "before after" design (#11) followed by cohort design (#2), randomised controlled trial (#2), experimental non randomised study and one cross sectional comparison. The measures of impact of registries were multifarious and included change in processes of care, quality of care, treatment outcomes, adherence to guidelines and survival. Sixteen of 17 studies

    One of the strategies for a good outcome and pain free childbearing is to design the delivery room. The aim of this study was to evaluate the effects of snoezelen room on childbearing outcome such as pain intensity, duration of labor, and perinea status in nulliparous women. This study was a randomized controlled clinical trial consists of 100 childbearing women. They were randomly divided into 2 groups. The experimental group went to snoezelen room when their cervix dilation was 4 cm, while the control group went to physiologic delivery room with the same cervix dilation. The mean ± SD of VAS (Visual Analogue Scale) pain intensity of the experimental and control groups before the intervention were 5.1 ± 1.95 and 5.58 ± 1.62, respectively (P = 0.13). The mean ± SD of VAS pain intensity scores of the experimental and control groups after 3 hours spending in their assigned rooms were 5.26 ± 0.86 and 9.56 ± 1.48, respectively (P = 0.01). The mean ± SD of the first stage scores of the experimental and control groups were 6.95 ± 0.97 and 8.41 ± 0.67, respectively (P = 0.042). About 92% of participants' intervention vs. 66% of control participants had perinea laceration (P = 0.041). According to the findings of the present study, distracting senses in snoezelen room decreases mother's pain intensity, the length of labor, and incidence of episiotomy.

    Few studies have examined the outcome of large numbers of patients with the microgranular variant (M3V) of acute promyelocytic leukemia (APL) in the all-trans retinoic acid era. Here, the outcome of 155 patients treated with all-trans retinoic acid–based therapy on 3 clinical trials, North American Intergroup protocol I0129 and Programa para el Estudio de la Terapéutica en Hemopatía Maligna protocols LPA96 and LPA99, are reported. The complete remission rate for all 155 patients was 82%, compared with 89% for 748 patients with classical M3 disease. The incidence of the APL differentiation syndrome was 26%, compared with 25% for classical M3 patients, and the early death rate was 13.6% compared with 8.4% for patients with classical M3 morphology. With a median follow-up time among survivors of 7.6 years (range 3.6-14.5), the 5-year overall survival, disease-free survival, and cumulative incidence of relapse for patients with M3V were 70%, 73%, and 24%, respectively. With a median follow-up time among survivors of 7.6 years (range 0.6-14.3), the 5-year overall survival, disease-free survival, and cumulative incidence of relapse among patients with classical M3 morphology were 80% (P = .006 compared with M3V), 81% (P = .07), and 15% (P = .005), respectively. When outcomes were adjusted for the white blood cell count or the relapse risk score, none of these outcomes were significantly different between patients with M3V and classical M3 APL.

    Background and study aims Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome caused by a germline mutation in the adenomatous polyposis coli (APC) gene, characterized by the presence of more than 100 adenomatous polyps in the colorectum. The upper gastrointestinal tract is an extracolonic site for malignancy in patients with FAP. The frequency of death in Japanese patients with FAP because of gastric cancer is 2.8 % and that because of colon cancer is 60.6 %. Few studies have reported upper gastrointestinal diseases in patients with FAP. In the present study, we investigated the clinical outcomes of patients with FAP diagnosed with gastric neoplasms. Patients and methods We enrolled 80 patients with FAP who underwent esophagogastroduodenoscopy from October 1997 to December 2011. We investigated patient characteristics, endoscopic findings of gastric lesions, treatment outcomes, and long-term courses. Results Fundic gland polyposis was observed in 51 patients (64 %) and gastric neoplasms in 22 patients (28 %), including 20 with non-invasive and 2 with invasive neoplasm. Of the 26 neoplasms, 11 were treated by endoscopic resection (ER) and 4 by surgical resection. Metachronous gastric neoplasms were observed in 7 patients (15 lesions) and treated by ER, except for in 1 patient. No patients died of gastric lesions during a median follow-up period of 6.5 years (range, 0 – 14). Conclusion Because gastric lesions including gastric cancers in patients with FAP did not cause any deaths, they can be considered to have favorable prognoses. Early detection of gastric neoplasms through an appropriate follow-up interval may have contributed to these good outcomes. PMID:28271094

    This prospective observational cohort study aimed to explore the clinical features of incident immune thrombocytopenia in adults and predictors of outcome, while determining if a family history of autoimmune disorder is a risk factor for immune thrombocytopenia. All adults, 18 years of age or older, recently diagnosed with immune thrombocytopenia were consecutively recruited across 21 hospital centers in France. Data were collected at diagnosis and after 12 months. Predictors of chronicity at 12 months were explored using logistic regression models. The association between family history of autoimmune disorder and the risk of developing immune thrombocytopenia was explored using a conditional logistic regression model after matching each case to 10 controls. One hundred and forty-three patients were included: 63% female, mean age 48 years old (Standard Deviation=19), and 84% presented with bleeding symptoms. Median platelet count was 10×109/L. Initial treatment was required in 82% of patients. After 12 months, only 37% of patients not subject to disease-modifying interventions achieved cure. The sole possible predictor of chronicity at 12 months was a higher platelet count at baseline [Odds Ratio 1.03; 95%CI: 1.00, 1.06]. No association was found between outcome and any of the following features: age, sex, presence of either bleeding symptoms or antinuclear antibodies at diagnosis. Likewise, family history of autoimmune disorder was not associated with incident immune thrombocytopenia. Immune thrombocytopenia in adults has been shown to progress to a chronic form in the majority of patients. A lower platelet count could be indicative of a more favorable outcome. PMID:27229715

    Malnutrition has been associated with increased morbidity and mortality. The objective of this study was to determine the nutritional status and micronutrient levels of hospitalized patients in an infectious disease clinic and investigate their association with adverse clinical outcomes. The nutritional status of the study participants was assessed using the Nutritional Risk Screening 2002 (NRS 2002) and micronutrient levels and routine biochemical parameters were tested within the first 24 h of the patient's admission. The incidence of zinc, selenium, thiamine, vitamin B6, vitamin B12 deficiency were 66.7% (n = 40), 46.6% (n = 29), 39.7% (n = 27), 35.3% (n = 24), 14.1% (n = 9), respectively. Selenium levels were significantly higher in patients with urinary tract infections, but lower in soft tissue infections. Copper levels were significantly higher in patients with soft tissue infections. In the Cox regression models, lower albumin, higher serum lactate dehydrogenase levels and higher NRS-2002 scores were associated with increased death. Thiamine, selenium, zinc and vitamin B6 deficiencies but not chromium deficiencies are common in infectious disease clinics. New associations were found between micronutrient levels and infection type and their adverse clinical outcomes. Hypoalbuminemia and a high NRS-2002 score had the greatest accuracy in predicting death, systemic inflammatory response syndrome and sepsis on admission.

    The Clinical and Laboratory Standards Institute (CLSI) lowered the MIC breakpoints for meropenem and imipenem from 4 mg/liter to 1 mg/liter for Enterobacteriaceae in 2010. The breakpoint change improves the probability of pharmacodynamic target attainment and eliminates the need for microbiology labs to perform confirmatory testing for Klebsiella pneumoniae carbapenemase (KPC) production or other beta-lactamases that hydrolyze carbapenems. However, there are limited data evaluating clinical outcomes of the affected breakpoints, and it is unknown if patients infected with Enterobacteriaceae with reduced susceptibility are more likely to have poor outcomes when treated with a carbapenem. We conducted a single-center retrospective matched-cohort analysis in adult patients with Enterobacteriaceae infections treated with meropenem, imipenem, or doripenem. Patients with Enterobacteriaceae infection with a carbapenem MIC of 2 to 8 mg/liter were matched based on pathogen, source of infection, comorbidities, and disease severity (1:1 ratio) to those with a carbapenem MIC of ≤1 mg/liter. A total of 36 patients were included in the study. The group with carbapenem MICs of 2 to 8 mg/liter had a significantly higher 30-day mortality than the group with carbapenem MICs of ≤1 mg/liter (38.9% compared to 5.6%, P = 0.04). Total hospital length of stay (LOS) and intensive care unit (ICU) LOS were longer in the group with MICs of 2 to 8 mg/liter than in the group with MICs of ≤1 mg/liter (57.6 days compared to 34.4 days [P = 0.06] and 56.6 days compared to 21.7 days [P < 0.01], respectively). Patients infected with Enterobacteriaceae with a carbapenem MIC of 2, 4, or 8 mg/liter had higher mortality rates and longer ICU LOS than matched cohorts with carbapenem MICs of ≤1 mg/liter, which supports CLSI's recommendation to lower susceptibility breakpoints for carbapenems.

    Idiopathic normal pressure hydrocephalus (iNPH) is a neurological disorder that classically presents with a triad of progressive gait impairment, urinary incontinence, and cognitive deterioration. Treatment predominantly involves ventriculoperitoneal (VP) shunting, but one alternative is ventriculoatrial (VA) shunting. This study sought to describe and evaluate the clinical outcomes of patients with iNPH primarily treated with VA shunting. A retrospective review of patients with iNPH who were treated with VA shunting at a single institution, from 2003 to 2013, was performed. 58 patients with iNPH underwent primary VA shunting at a median age of 74 (IQR: 70-80) years. The most common comorbidities included hypertension (n=39, 67%) and diabetes mellitus (n=11, 19%). Median duration of symptoms prior to VA shunting was 24 (IQR: 12-36) months. All patients had gait impairment, 52 (90%) had cognitive decline, and 43 (74%) had urinary incontinence. Forty-three (74%) patients had all three symptoms. At a median last follow-up of 16 (IQR: 7-26) months, median iNPH score improved from 6 to 3 (p<0.0001), mini mental status exam (MMSE) tended to increase from 26 to 29 (p=0.082), timed up-and-go (TUG) improved from 18 to 13s (p<0.0001), and Tinetti score improved from 19 to 25 (p<0.0001) after VA shunting. 78% of patients had improvement in at least one of their symptoms with 66% of patients having improvement in gait, 53% having improvement in their cognition, and 52% having improved urinary incontinence. A total of 21 patients (36%) had improvement in all 3 symptoms. There were significant improvements in functional outcomes as evaluated via the iNPH score, TUG, and Tinetti score, while improvement in MMSE trended toward significance. Patients also had improvement of clinical symptoms related to gait, urinary function and cognition. These results suggest that VA shunting can be an effective primary treatment alternative to VP shunting for iNPH. Published by Elsevier B.V.

    The diagnosis of pulmonary embolism (PE) still requires long work-up periods and multiple tests. We aim to assess clinical outcomes after a negative investigation using a combined protocol of CT pulmonary angiography and CT venography (CTA/CTV) as a sole diagnostic test in unselected patients with suspected PE. This retrospective cohort study enrolled consecutive patients with suspected PE who were investigated with a combined CTA/CTV protocol. Patients who had an initially negative investigation and were not anticoagulated were followed for 6 months for the occurrence of recurrent venous thromboembolic events. Out of 425 patients with suspected PE, 62 (14.6%) had venous thromboembolism diagnosed on the initial CTA/CTV. The mean age was 56 ± 19 years and 61% of the population fell into the low clinical probability category. Isolated deep vein thrombosis represented 21% of all venous thromboembolic events, and when considering the whole population, CTV was associated with an increment in diagnostic yield of 3.1%. Our cohort was composed of 320 patients with initially negative CTA/CTVs and who were not anticoagulated. After 6 months of follow up, only three patients presented with recurrent thromboembolic events (0.9%; 95% CI -0.1% - 2.0%) and none was fatal. There were no PE-related deaths. Our study suggests that a diagnostic strategy that utilizes CTA/CTV as a sole diagnostic test can safely rule out PE in a low to moderate risk population and is associated with favorable outcomes with a negative predictive value of 99.1%.

    The aim of this study was to describe the clinical findings and outcome in suicidal attempted due to intravenous injection of kerosene. This case series study was conducted in the Department of Internal Medicine, Shohada Ashayer Hospital, Khorramabad, Iran during 8 years. Ten IV drug addicts who intravenously injected themselves with Kerosene were collected. All patients admitted in ICU, completely monitored for cardiopulmonary status and consulted with pulmonologist, cardiologist, neurologist, anesthesiologist and dermatologist. Therapeutic decision including intubation, antibiotics therapy, and oxygen, correction of water and electrolyte disturbances was applied according patients condition. The data were analyzed with fisher-exact test. Nine (90%) patients were male, 1(10%) was female. All cases were attempted suicides and IV drug abusers. Mean age was 20.3 +/- 2 years. The patients' mean arrival time to the hospital after poisoning was 1.1 h. Death of 5(50%) patients was related to the higher doses (>5 mL) of intravenous injection of kerosene, the most clinical findings were related to pulmonary involvement with pulmonary edema and subsequent cardiac and neurological complications and phlebitis due to IV injection. Intravenous kerosene injection causes major injury to the lungs, the organ bearing the first capillary bed encountered. Other complications including cardiac and neurological seems to be related to severe hypoxia and other metabolic disturbances due to lung injury. The amounts of kerosene were major determinants of lethality. Early and aggressive supportive care might be conducive to a favorable outcome with minimal residual pulmonary squeal at least in patients with injection of less than 5 mL of kerosene.

    Ornithine transcarbamylase (OTC) deficiency is an X-linked inborn error of the urea cycle that leads to the accumulation of ammonia, resulting in neurological deficits. This study was performed to describe the clinical outcomes, biochemical features and molecular spectra of patients with OTC deficiency. A total of 49 patients from 47 unrelated Korean pedigrees were included who were diagnosed with OTC deficiency based on biochemical findings and molecular analyses. Patient clinical features,biochemical findings and molecular data were analyzed retrospectively. Males with neonatal-onset phenotype presented with seizure or altered mentality (n=20). Biochemical findings showed high blood ammonia (1132.5±851.6 μmol l (− 1)) and urineorotic acid (1840.7±1731.3 mmol mol(− 1) Cr) levels. There were also five males with late-onset disease who presented with vomiting, irritability and seizure at age 8.2±9.4 years old (range, 0.6–20 years). Symptomatic females presented with vomiting,seizure, and altered mentality at age 3.5±3.5 years (range, 0.2–12.8 years; n=24). More males with the late-onset form and symptomatic females displayed mild hyperammonemia and orotic aciduria compared with those showing a neonatal phenotype (P<0.05). Molecular analysis identified 37 different mutations (22 missense, 5 large deletions, 4 small deletions, 1 insertion,3 nonsense and 2 splice sites) from all 49 patients; the mutations were dispersed throughout all coding exons. In Korean patients with OTC deficiency, mutations in OTC are genetically heterogeneous. Male patients with the neonatal-onset phenotype showed poor outcomes because of severe hyperammonemia. Early diagnosis and interventions for hyperammonemia can provide more favorable prognosis.

    The superiority of everolimus-eluting stents (EES) over sirolimus-eluting stents (SES) for long-term clinical outcomes has not been yet firmly established. We conducted a systematic review and a meta-analysis of randomized controlled trials (RCTs) comparing EES directly with SES using the longest available follow-up data. We searched PubMed, the Cochrane database, and ClinicalTrials.gov for RCTs comparing outcomes between EES and SES and identified 13,434 randomly assigned patients from 14 RCTs. EES was associated with significantly lower risks than SES for definite stent thrombosis (ST), definite/probable ST, target-lesion revascularization (TLR), and major adverse cardiac events (MACE). The risks for all-cause death and myocardial infarction were similar between EES and SES. By the stratified analysis according to the timing after stent implantation, the favorable trend of EES relative to SES for ST, TLR, and MACE was consistently observed both within and beyond 1 year. The lower risk of EES relative to SES for MACE beyond 1 year was statistically significant (pooled odds ratio 0.77, 95% confidence interval 0.61 to 0.96, p = 0.02). In conclusion, the current meta-analysis of 14 RCTs directly comparing EES with SES suggested that EES provided improvement in both safety and efficacy; EES compared with SES was associated with significantly lower risk for definite ST, definite/probable ST, TLR, and MACE. The direction and magnitude of the effect beyond 1 year were comparable with those observed within 1 year.

    Background Kaposi sarcoma (KS) is one of the most common pediatric cancers in sub-Saharan Africa. Few data are available about the clinical presentation or response to treatment of children with epidemic (HIV-associated) KS. Methods Medical records of all children with KS and HIV infection referred to the Uganda Cancer Institute in Kampala, Uganda from October 2004 to June 2007 were reviewed. Charts were abstracted for age, sex, location of KS lesions at presentation, biopsy results, CD4 T-cell count and percentage, and KS treatment and outcome. Results Seventy-three children with epidemic KS were identified, 37 males and 36 females. The median age was 10.1 years (range 2 - 18). KS presented with lymph node involvement in 60% of cases. The median absolute and percentage CD4 T-cells at presentation were 210 cells/uL and 7.4%, respectively. Those children with lymphadenopathic KS were younger (mean difference 3.7 years; p = 0.01) and had higher CD4 T-cell counts (mean difference 242 cells/uL; p = 0.03) than those without lymph node involvement. Of 32 patients for whom outcome data were available, a complete response to chemotherapy and/or antiretroviral therapy was documented in 20 (62.5%) patients. Conclusions In comparison to cutaneous involvement, lymph node involvement of epidemic KS occurs at younger ages and at higher CD4 levels. This clinical presentation may reflect recent infection with human herpesvirus 8 followed by a rapid progression to malignancy. Favorable response to treatment was observed in the majority of cases, but prospective studies are needed to determine optimal management. PMID:20205254

    To facilitate comparative clinical outcome research in low vision rehabilitation, we must use patient-centered measurements that reflect clinically meaningful changes in visual ability. To quantify the effects of currently provided low vision rehabilitation (LVR) on patients who present for outpatient LVR services in the United States. Prospective, observational study of new patients seeking outpatient LVR services. From April 2008 through May 2011, 779 patients from 28 clinical centers in the United States were enrolled in the Low Vision Rehabilitation Outcomes Study. The Activity Inventory, a visual function questionnaire, was administered to measure overall visual ability and visual ability in 4 functional domains (reading, mobility, visual motor function, and visual information processing) at baseline and 6 to 9 months after usual LVR care. The Geriatric Depression Scale, Telephone Interview for Cognitive Status, and Medical Outcomes Study 36-Item Short-Form Health Survey physical functioning questionnaires were also administered to measure patients' psychological, cognitive, and physical health states, respectively, and clinical findings of patients were provided by study centers. Mean changes in the study population and minimum clinically important differences in the individual in overall visual ability and in visual ability in 4 functional domains as measured by the Activity Inventory. Baseline and post-rehabilitation measures were obtained for 468 patients. Minimum clinically important differences (95% CIs) were observed in nearly half (47% [95% CI, 44%-50%]) of patients in overall visual ability. The prevalence rates of patients with minimum clinically important differences in visual ability in functional domains were reading (44% [95% CI, 42%-48%]), visual motor function (38% [95% CI, 36%-42%]), visual information processing (33% [95% CI, 31%-37%]), and mobility (27% [95% CI, 25%-31%]).

    To describe the clinical characteristics and surgical outcomes of a group of patients with age-related distance esotropia (ARDE). A retrospective study was conducted on a consecutive case series of 16 adult patients diagnosed with ARDE between 2008 and 2015. The clinical features evaluated included mean age and gender, primary position deviations at distance and near, measured in prism dioptres (pd), treatment offered in each case, and post-surgical deviations. Ductions and versions were full, with no evidence of lateral rectus paresis. None of these patients had any obvious underlying neurological disorder, such as, high myopia or thyroid disease. A good result is considered to be the disappearance of diplopia in all positions of gaze. A total of 16 patients (11 females [68.8%]) were identified. The mean age at diagnosis was 78.19±6.77 years. The mean initial esodeviation was 2.25±3.08 pd at near (-4 to +8 pd) and 9.5±4.18 pd at distance (2 to 18 pd). Treatment was not necessary in 5 cases because the symptoms were intermittent or well-tolerated. Of the 11 patients with symptoms, one was corrected with an external base therapeutic prism. Botulinum toxin was administered in another patient, without satisfactory results. Unilateral medial rectus muscle recession was performed on one patient, and unilateral lateral rectus plication on 7 patients, indicating prisms before surgery. One patient refused surgery despite continuous diplopia in far vision. After a mean follow-up of 16.5 months, all operated patients were asymptomatic. Not all patients with ARDE require treatment, as the tolerance to diplopia varies from one subject to another. Both medial rectus weakening and lateral rectus strengthening provides excellent results. Crown Copyright © 2016. Publicado por Elsevier España, S.L.U. All rights reserved.

    Blastomycosis is an uncommon granulomatous infection caused by the thermally dimorphic fungus Blastomyces dermatitidis. The most frequent clinical infections involve the lung, skin, and bone. Pulmonary manifestations range from asymptomatic self-limited infection to severe diffuse pneumonia causing respiratory failure. To establish the clinical characteristics and outcomes of patients with pulmonary blastomycosis diagnosed at hospitals in Manitoba and northwestern Ontario, Canada. A retrospective review of medical records was done for 318 patients with blastomycosis in these regions. The majority of patients were Caucasian (198 (62.5%) patients), male (193 (61%) patients), and residents of Ontario (209 (65.7%) patients). Most patients were treated in an inpatient hospital ward (266 (84%) patients) and survived (294 (92%) patients). Pulmonary involvement, either alone or associated with other sites, was present in 296 (93%) of the 318 patients; 22 (7%) patients had no evidence of pulmonary blastomycosis. The majority of patients had localized lung disease (1-3 quadrants on chest radiograph involved; 225 (82%) patients). Of 294 (92%) patients requiring hospitalization, 266 (90%) patients received all inpatient care on a general medical ward; 28 (10%) patients received some care in the intensive care unit (ICU). Factors associated with ICU admission included diffuse pulmonary disease (four quadrants involved on chest radiograph), diabetes, and prior use of antimicrobial therapy. Twenty-four (8%) patients died, and multivariate analysis showed that older age and Aboriginal ethnicity were the significant risk factors for death from blastomycosis. Blastomycosis is a cause of serious, potentially life-threatening pulmonary infection in this geographic region.

    Objective Pituitary apoplexy (PA) is described as a clinical syndrome characterized by sudden headache, vomiting, visual impairment, and meningismus caused by rapid enlargement of a pituitary adenoma. We retrospectively analyzed the clinical presentation and surgical outcome in PA presenting with cranial neuropathy. Methods Twelve cases (3.3%) of PA were retrospectively reviewed among 359 patients diagnosed with pituitary adenoma. The study included 6 males and 6 females. Mean age of patients was 49.0 years, with a range of 16 to 74 years. Follow-up duration ranged from 3 to 20 months, with an average of 12 months. All patients were submitted to surgery, using the transsphenoidal approach (TSA). Results Symptoms included abrupt headache (11/12), decreased visual acuity (12/12), visual field defect (11/12), and cranial nerve palsy of the third (5/12) and sixth (2/12). Mean height of the mass was 29.0 mm (range 15-46). Duration between the ictus and operation ranged from 1 to 15 days (mean 7.0). The symptom duration before operation and the recovery period of cranial neuropathy correlated significantly (p = 0.0286). TSA resulted in improvement of decreased visual acuity in 91.6%, visual field defect in 54.5%, and cranial neuropathy in 100% at 3 months after surgery. Conclusion PA is a rare event, complicating 3.3% in our series. Even in blindness following pituitary apoplexy cases, improvement of cranial neuropathy is possible if adequate management is initiated in time. Surgical decompression must be considered as soon as possible in cases with severe visual impairment or cranial neuropathy. PMID:21082047

    Endogenous regenerative capacity, assessed as circulating progenitor cell (PC) numbers, is an independent predictor of adverse outcomes in patients with cardiovascular disease. However, their predictive role in heart failure (HF) remains controversial. We assessed the relationship between the number of circulating PCs and the pathogenesis and severity of HF and their impact on incident HF events. We recruited 2049 adults of which 651 had HF diagnosis. PCs were enumerated by flow cytometry as CD45med(+) blood mononuclear cells expressing CD34, CD133, vascular endothelial growth factor receptor-2, and chemokine (C-X-C motif) receptor 4 epitopes. PC subsets were lower in number in HF and after adjustment for clinical characteristics in multivariable analyses, a low CD34(+) and CD34(+)/CXCR(+) cell count remained independently associated with a diagnosis of HF (P<0.01). PC levels were not significantly different in reduced versus preserved ejection fraction patients. In 514 subjects with HF, there were 98 (19.1%) all-cause deaths during a 2.2±1.5-year follow-up. In a Cox regression model adjusting for clinical variables, hematopoietic-enriched PCs (CD34(+), CD34(+)/CD133(+), and CD34(+)/CXCR4(+)) were independent predictors of all-cause death (hazard ratio 2.0, 1.6, 1.6-fold higher mortality, respectively; P<0.03) among HF patients. Endothelial-enriched PCs (CD34(+)/VEGF(+)) were independent predictors of mortality in patients with HF with preserved ejection fraction only (hazard ratio, 5.0; P=0.001). PC levels are lower in patients with HF, and lower PC counts are strongly and independently predictive of mortality. Strategies to increase PCs and exogenous stem cell therapies designed to improve regenerative capacity in HF, especially, in HF with preserved ejection fraction, need to be further explored. © 2017 American Heart Association, Inc.

    Introduction Prophylactic appendicectomy is performed prior to military, polar and space expeditions to prevent acute appendicitis in the field. However, the risk–benefit ratio of prophylactic surgery is controversial. This study aimed to systematically review the evidence for prophylactic appendicectomy. It is supplemented by a clinical example of prophylactic surgery resulting in life-threatening complications. Methods A systematic review was performed using MEDLINE® and the Cochrane Central Register of Controlled Trials. Keyword variants of ‘prophylaxis’ and ‘appendicectomy’ were combined to identify potential papers for inclusion. Papers related to prophylactic appendicectomy risks and benefits were reviewed. Results Overall, 511 papers were identified, with 37 papers satisfying the inclusion criteria. Nine reported outcomes after incidental appendicectomy during concurrent surgical procedures. No papers focused explicitly on prophylactic appendicectomy in asymptomatic patients. The clinical example outlined acute obstruction secondary to adhesions from a prophylactic appendicectomy. Complications after elective appendicectomy versus the natural history of acute appendicitis in scenarios such as polar expeditions or covert operations suggest prophylactic appendicectomy may be appropriate prior to extreme situations. Nevertheless, the long-term risk of adhesion related complications render prophylactic appendicectomy feasible only when the short-term risk of acute appendicitis outweighs the long-term risks of surgery. Conclusions Prophylactic appendicectomy is rarely performed and not without risk. This is the first documented evidence of long-term complications following prophylactic appendicectomy. Surgery should be considered on an individual basis by balancing the risks of acute appendicitis in the field with the potential consequences of an otherwise unnecessary surgical procedure in a healthy patient.

    To evaluate clinical outcome in a 10-year consecutive series of children operated for sellar and parasellar tumors with special focus on neuropsychology and endocrinology. We analyzed 61 children (30 female) under 18 years of age (mean age 9.9, range 1 month-17 years) operated between 2000 and 2010. Medical records were evaluated retrospectively; postoperative histologic diagnoses included 20 craniopharyngiomas, 17 gliomas, 6 pituitary adenomas and 18 rare tumor entities. Of 61 patients, 58 (95%) were still alive at last follow-up. Three patients died, all due to progression of malignant rhabdoid tumors. Postoperative clinical morbidity consisted of endocrinological (66%), visual (60.7%) and other neurological deficits (55.9%) after a mean follow-up of 44 months. When compared to all other tumor entities in this series, craniopharyngiomas were associated with high rates of gross-total resection (p=0.008), frequent progression of residual tumor (p=0.005) scotomas (p=0.013), persistent diabetes insipidus (p<0.001), and panhypopituitarism (p<0.001). Surgically treated gliomas showed higher rates of motor weakness (p=0.004), double vision (p<0.001), and milder forms of endocrinopathy (single hormone deficits, p=0.02). In general, deterioration in school performance was associated with multiple surgeries (p=0.018) and radiotherapy (p=0.021). Excellent overall survival in these patients is possible, however malignant rhabdoid tumors have a poor prognosis. Aggressive treatment is associated with significant morbidity. Children operated for craniopharyngioma showed an expected high rate of endocrine deterioration, whereas glioma patients had higher incidences of motor weakness and double vision. The treating physicians should be well aware of all these considerable postoperative deficits, especially when facing interdisciplinary management decisions, and for the informed consent discussions with the patient and the parents.

    An important principle in the good conduct of clinical trials is that a summary of the trial protocol, with a pre-defined primary outcome, should be freely available before the study commences. The clinical trials registry ClinicalTrials.gov provides one method of doing this, and once the trial is registered, any changes made to the primary outcome are documented. The objectives of this study were: to assess the proportion of registered trials on ClinicalTrials.gov that had the primary outcome changed; to assess when the primary outcome was changed in relation to the listed study start and end dates and to assess whether the primary outcome change had any relation to the study sponsor. A cross-sectional analysis of all interventional clinical trials registered on ClinicalTrials.gov as of 25 October 2012 was performed. The main outcome was any change made to the initially listed primary outcome and the time of the change in relation to the trial start and end date. Our analysis showed that 28229 of 89204 (31.7%) registered studies had their primary outcome changed.  Industry funding was associated with all primary outcome changes, odds ratio (OR)= 1.36, 95% confidence interval (CI)=1.31-1.41, p<0.001; with primary outcome changes after study start date OR=1.37, 95% CI=1.32-1.42, p<0.001; with primary outcome changes after primary completion date OR=1.84, 95% CI=1.75-1.94, p<0.001 and with primary outcome changes after study completion date OR=1.82, 95% CI=1.73-1.91, p<0.001.  Conclusions A significant proportion of interventional trials registered on ClinicalTrials.gov have their primary outcomes altered after the listed study start and completion dates. These changes are associated with funding source.

    Purpose: Proton radiotherapy (PT) has been prescribed similarly to photon radiotherapy to achieve comparable disease control rates at comparable doses. The chief advantage of protons in this setting is to reduce acute and late toxicities by decreasing the amount of normal tissue irradiated. We report the preliminary clinical outcomes including late effects on our pediatric Ewing's sarcoma patients treated with PT at the Francis H. Burr Proton Therapy Center at Massachusetts General Hospital (Boston, MA). Methods and Materials: This was a retrospective review of the medical records of 30 children with Ewing's sarcoma who were treated with PT between April 2003 and April 2009. Results: A total of 14 male and 16 female patients with tumors in several anatomic sites were treated with PT at a median age of 10 years. The median dose was 54 Gy (relative biological effectiveness) with a median follow-up of 38.4 months. The 3-year actuarial rates of event-free survival, local control, and overall survival were 60%, 86%, and 89%, respectively. PT was acutely well tolerated, with mostly mild-to-moderate skin reactions. At the time of writing, the only serious late effects have been four hematologic malignancies, which are known risks of topoisomerase and anthracyline exposure. Conclusions: Proton radiotherapy was well tolerated, with few adverse events. Longer follow-up is needed to more fully assess tumor control and late effects, but the preliminary results are encouraging.

    This study examined the clinical characteristics and outcome of pulmonary tuberculosis in African Americans hospitalized in a teaching hospital in south-central Los Angeles from May 1992 through April 1994. The charts of 41 African Americans with culture-positive Mycobacterium tuberculosis were reviewed. Predisposing factors for pulmonary tuberculosis were identified in nearly half of cases. Cough and fever were the most common symptoms. Seventy-six percent had positive acid-fast bacilli (AFB) smears. Nine patients were human immunodeficiency virus (HIV)-positive, and 6 of 9 HIV-positive patients had positive AFB smears whereas 17 of 19 HIV-negative patients had positive AFB smears. Radiographic changes were not significantly different between HIV-positive and HIV-negative patients. Drug resistance was identified in nine of 31 patients (29%). Eight of 41 patients (19.5%) died, with 2 being drug resistant. Human immunodeficiency virus infection was a major predisposing factor for tuberculosis, and no statistical differences were found in radiographic features or AFB smear positivity between HIV-positive and HIV-negative patients. Drug resistance and mortality were disproportionately high. These results indicate that HIV infection and drug resistance are major problems that predispose for tuberculosis infection and make its treatment difficult. PMID:9510620

    To report the clinical and microbiological profile of patients with microsporidial keratoconjunctivitis in a tertiary eye care centre in India. A retrospective analysis of medical records of all cases of microbiologically confirmed microsporidial keratoconjunctivitis, who presented between March 2007 and October 2010, was done. In a single-centre, institutional setting, 278 eyes of 277 apparently healthy patients were analysed. The mean age was 36 ± 14 years (range 6-80). The mean duration of symptoms was 7.7 ± 6.2 days (range 1-60). Keratic precipitates were present in 20.1% patients. A superficial scar was present in 39.2% patients. Majority (26.6%) of the patients reported in the month of August. Microscopic examination of corneal scraping, using potassium hydroxide with calcofluor white and Gram stain, demonstrated microsporidial spores in 98.9% and 89.7% cases, respectively. Patients received either topical 0.02% polyhexamethylene biguanide or lubricants. The mean time for resolution was 6.0 ± 2.9 days (range 2-18). Final visual acuity was ≥ 20/30 in 75.1% cases. Microsporidial keratoconjunctivitis is common in India. It is seasonal, can occur in healthy individuals and can be diagnosed using simple microbiological methods. Treatment outcome is generally satisfactory.

    The present comparative evaluation aims at establishing whether the basic structure of dialysis membrane is able to predict long-term clinical outcome. From a population of 1,256 patients on renal dialysis treatment, treated by the Institute of Nephrology and Dialysis of the St. Orsola University Hospital of Bologna from 1963 to 1993, 122 patients were retrospectively selected for the present study. Patients were divided into two different groups according to the kind of dialysis membrane used--cellulose-based (64 patients) and synthetic-based (58 patients) membranes. The parameters considered were: intradialytic biology, long-term biocompatibility, survival and morbidity, and cost/benefit. The results obtained demonstrate that cellulosic membranes can be said to cause a greater acute intradialytic biological response than synthetics, though not to a significant degree. There are, however, no significant differences in the biological changes from group to group. Nonsignificant differences were noted in long-term survival general morbidity. In terms of sheer cost, synthetic membrane treatment is anything up to 200% dearer than cellulosic.

    THE PROBLEM OF MANAGING DEMAND: Most healthcare systems have 'third-party payers' who face the problem of keeping within budgets despite pressures to increase resources due to the ageing population, new technologies and patient demands to lower thresholds for care. This paper uses the UK National Health Service as a case study to suggest techniques for system-based demand management, which aims to control demand and costs whilst maintaining the cost-effectiveness of the system. The technique for managing demand in primary, elective and urgent care consists of managing treatment thresholds for appropriate care, using a whole-systems approach and costing the care elements in the system. It is important to analyse activity in relation to capacity and demand. Examples of using these techniques in practice are given. The practical effects of using such techniques need evaluation. If these techniques are not used, managing demand and limiting healthcare expenditure will be at the expense of clinical outcomes and unmet need, which will perpetuate financial crises.

    Autogenic training (AT) is a self-relaxation procedure by which a psychophysiological determined relaxation response is elicited. A meta-analysis was performed to evaluate the clinical effectiveness of AT. Seventy-three controlled outcome studies were found (published 1952-99). Sixty studies (35 randomized controlled trials [RCT]) qualified for inclusion in the meta-analysis. Medium-to-large effect sizes (ES) occurred for pre-post comparisons of disease-specific AT-effects, with the RCTs showing larger ES. When AT was compared to real control conditions, medium ES were found. Comparisons of AT versus other psychological treatment mostly resulted in no effects or small negative ES. This pattern of results was stable at follow-up. Unspecific AT-effects (i.e., effects on mood, cognitive performance, quality of life, and physiological variables) tended to be even larger than main effects. Separate meta-analyses for different disorders revealed a significant reduction of the heterogeneity of ES. Positive effects (medium range) of AT and of AT versus control in the meta-analysis of at least 3 studies were found for tension headache/migraine, mild-to-moderate essential hypertension, coronary heart disease, asthma bronchiale, somatoform pain disorder (unspecified type), Raynaud's disease, anxiety disorders, mild-to-moderate depression/dysthymia, and functional sleep disorders.

    Background: Matrix-assisted autologous chondrocyte transplantation (MACT) is a surgical treatment option for articular cartilage lesions of the knee joint. Purpose: To investigate mid- to long-term clinical outcomes of MACT in the patellofemoral (PF) and tibiofemoral (TF) joints. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was performed by searching PubMed, Embase, and the Cochrane Library to find studies evaluating minimum 5-year clinical outcomes of patients undergoing MACT in the knee joint. Search terms used were knee, matrix, and autologous chondrocyte. Patients were evaluated based on treatment failure rates, magnetic resonance imaging, and subjective outcome scores. Study methodology was assessed using the Modified Coleman Methodology Score (MCMS). Results: Ten studies (two level 1, one level 2, one level 3, and six level 4 evidence) were identified that met inclusion and exclusion criteria, for a total of 442 TF patients and 136 PF patients. Treatment failure occurred in 9.7% of all patients, including 4.7% of PF patients and 12.4% of TF patients (P = .037). Weighted averages of subjective outcome scores, including Knee injury and Osteoarthritis Outcome Score, Short Form–36 Health Survey, and Tegner scores, improved from baseline to latest follow-up in both TF and PF patients. The mean MCMS was found to be 57.4, with a standard deviation of 18.5. Conclusion: Patients undergoing MACT in the knee show favorable mid- to long-term clinical outcomes. A significantly higher treatment failure rate was found in patients undergoing MACT in the TF joint compared with the PF joint. PMID:28620621

    In this study, we aimed to assess the levels of B cell activating factor from the tumor necrosis factor family (BAFF) and a proliferation-inducing ligand (APRIL) in cerebrospinal fluid (CSF) of patients with anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis and determine their correlation with clinical outcome. BAFF and APRIL concentrations in CSF and serum from 40 patients with anti-NMDAR encephalitis and 20 controls were measured by enzyme-linked immunosorbent assay (ELISA). Compared with controls, the levels of both BAFF and APRIL in CSF were significantly increased in patients with anti-NMDAR encephalitis (p<0.001 and p<0.001). Patients with unfavorable outcome had higher levels of BAFF and APRIL in CSF than those who had favorable outcome (p<0.05 and p<0.05). BAFF and APRIL levels in CSF were elevated and associated with clinical outcome in patients with anti-NMDAR encephalitis, indicating that they may be valuable biomarkers to this disease.

    Endodontic intervention in necrotic immature permanent teeth is usually a clinical challenge. With appropriate case selection, regenerative treatment can be effective, providing a desirable outcome. However, there is still no consensus on the optimal disinfection protocol or the method to achieve predictable clinical outcome. This article presents two cases of regenerative treatment in necrotic immature teeth, using mineral trioxide aggregate (MTA) and BiodentineTM as coronal barriers and different irrigants, which led to different clinical outcomes.

    Presently, no studies have evaluated clinical outcomes or patient-centered outcomes for complete dentures fabricated with computer-aided design and computer aided manufacturing (CAD/CAM) technology. The purpose of this prospective cohort pilot study was to evaluate the clinical and patient-centered outcomes for CAD/CAM monolithic dentures fabricated in 2 visits. Twenty participants with an existing set of maxillary complete dentures opposing either mandibular complete dentures or implant-retained overdentures that required replacement were recruited in this study. A 2-visit duplicate denture protocol was used to fabricate 40 arches of monolithic dentures with CAD/CAM technology. A 100-mm visual analog scale (VAS) instrument was then used to record 12 outcomes at baseline and at 1-year follow-up. Predetermined values were assigned to grade the VAS rating of each outcome as favorable (70.1-100) and unfavorable (≤70). Favorable ratings were sub-divided as excellent (90.1-100), good (80.1-90), and fair (70.1-80). The clinical outcomes were evaluated independently by 2 experienced prosthodontists at baseline and at 1-year follow-up. Patients evaluated the corresponding patient-centered outcomes during the same time intervals. Additional descriptive variables were also recorded. Each clinical and patient-centered outcome was summarized by medians and ranges. Differences in all ratings recorded at baseline and at 1 year were tested by 1-sided sign test (α=.05). Of 20 participants, 3 were lost to follow-up, and 3 were unsatisfied with the digital dentures and withdrew from the study. These 3 participants were considered treatment failures. Of the 14 remaining participants, 9 had implant-retained mandibular overdentures, and 5 had conventional mandibular complete dentures. For clinical outcomes, the 12 studied outcomes were favorably evaluated by the 2 prosthodontist judges at the 1-year follow-up. Evaluations showed minimal differences between baseline and 1 year. An

    The survival of patients with metastatic breast cancer (MBC) has not improved, despite recent advances in therapeutic strategies. This is mainly due to the fact that cytotoxic agents cannot be administered over a long period, even if they exhibit favorable activity, due to treatment-related side effects or acquisition of tumor resistance to the administered agents. Thus, the development of therapeutic strategies that may be used over a long time period is required to improve survival. We assessed the availability and clinical outcomes of metronomic chemotherapy, which is defined as continuous or frequent treatment with low doses of cytotoxic drugs. A total of 80 patients with MBC received chemotherapy in the metastatic setting, and the clinicopathological factors and clinical outcomes were retrospectively compared between 52 patients who received metronomic regimens and 28 patients who received other cytotoxic regimens. As regards clinical outcomes, the median time-to-treatment failure (TTF) and overall survival (OS) were significantly longer in the metronomic group compared with those in the non-metronomic group (TTF, 15 vs. 4 months, P=0.0001; and OS, 53 vs. 28 months P=0.0012, respectively). In the metronomic group, none of the 18 patients who responded to the regimen had triple-negative (TN) cancer (17 had luminal-type tumors and 1 had a human epidermal factor receptor 2-type tumor). Furthermore, TTF and OS were significantly longer in patients with non-TN cancer compared with those in patients with TN cancer in the metronomic group (TTF, 16 vs. 7 months, P=0.0014; and OS, 108 vs. 20 months, P=0.000007, respectively). The proportion of patients who experienced treatment-related adverse events was significantly lower in the metronomic group compared with that in the non-metronomic group (36.5 vs. 61.5%, respectively; P=0.038). In conclusion, metronomic chemotherapy is a viable option for luminal-type MBC in terms of effectiveness and minimal toxicity, regardless

    To evaluate the risk factors, presentation, and outcomes in cases of abdominal wall endometriosis. A case-control study (Canadian Task Force classification II-2). An academic medical center. A total of 102 (34 cases and 68 controls) were included. Surgical resection of abdominal wall endometriosis. Cases underwent surgical excision for abdominal wall endometriosis at Mayo Clinic from January 1, 2000, through December 31, 2013. For each case, 2 controls were randomly selected from a list of women who had surgery in the same year with minimal (American Society for Reproductive Medicine stage I-II) endometriosis. A chart review was completed for variables of interest. Regression models were used to identify independent risk factors associated with abdominal wall endometriosis. In 14 years, 2539 women had surgery for endometriosis at Mayo Clinic. Of these, only 34 (1.34%) had abdominal wall endometriosis. The mean age was 35.2 ± 5.9 years, and the median parity was 2 (range, 0-5). Clinical examination diagnosed abdominal wall endometriosis in 41% of cases, with the cesarean delivery scar being the most common site (59%). There was a strong correlation between the size of the lesion on clinical examination compared with the size of the pathology specimen (r(2) = 0.74, p < .001). When compared with controls, cases had significantly higher parity and body mass index, more cyclic localized abdominal pain, less dysmenorrhea, longer duration from the start of symptoms to surgery, and more gynecologic surgeries for symptoms without cure. In the final multivariable model, cyclic localized abdominal pain, absence of dysmenorrhea, and previous laparotomy were independently associated with abdominal wall endometriosis with adjusted odds ratios of 10.6 (95% CI 1.85-104.4, p < .001), 12.4 (95% CI 1.64-147.1, p < .001), and 70.1 (95% CI 14.8-597.7, p < .001), respectively, with an area under the curve for the receiver operating characteristic of 0.94 (95% CI, 0

    Tuberculum sellae meningiomas present a special challenge because of their proximity to arteries of the anterior circulation, anterior visual pathways, and the hypothalamus. The authors report on the clinical outcome after surgical treatment of tuberculum sellae meningiomas in our neurosurgical department. A retrospective study was conducted analyzing the charts of the patients, including surgical records, discharge letters, histological records, follow-up records, and imaging studies. Patients with associated neurofibromatosis Type 2 were excluded from the study. One thousand eight hundred meningiomas were operated on between 1978 and 2002. Seventy-two of these patients had tuberculum sellae meningiomas; four had undergone previous surgical procedures in outside hospitals. Fifty-five patients were women; 17 were men. Their mean age was 54.3 years (range, 30-86 yr). All patients had visual disturbances at presentation. Tumors were operated through the bifrontal approach (n = 21, from 1978 through 1995), the pterional/frontotemporal approach (n = 21, from 1982 through 2002), and the frontolateral approach (n = 30, from 1984 through 2002). Total tumor removal was achieved in most patients (Simpson 1 + 2, 91.7%). The perioperative mortality rate was 2.8% (two out of 72 patients). Immediate postoperative improvement of visual disturbance was observed in 65% of patients. Visual improvement was dependent on the duration of preoperative visual symptoms, but not on preoperative visual acuity or tumor size. The visual improvement rate was significantly better in patients who underwent frontolateral tumor resection (77.8%) compared with those who underwent bifrontal craniotomy (46.2%). The overall recurrence rate was 2.8% (two out of 72 patients). The mean follow-up time for all patients was 4 to 238 months (mean, 45.3 mo [3.8 yr]). From 1978 through 2002, tuberculum sellae meningiomas were removed microsurgically us
