    Despite increasing awareness of obstetric safety initiatives, maternal mortality and severe maternal morbidity in the United States have continued to increase over the past 20 years. Since results from large-scale surveillance programs suggest that up to 50% of maternal deaths may be preventable, new efforts are focused on developing and testing early warning systems for the obstetric population. Early warning systems are a set of specific clinical signs or symptoms that trigger the awareness of risk and an urgent patient evaluation, with the goal of reducing severe morbidity and mortality through timely diagnosis and treatment. Early warning systems have proven effective at predicting and reducing mortality and severe morbidity in medical, surgical, and critical care patient populations; however, there has been limited research on how to adapt these tools for use in the obstetric population, where physiologic changes of pregnancy render them inadequate. In this article, we review the available obstetric early warning systems and present evidence for their use in reducing maternal mortality and severe maternal morbidity. We also discuss considerations and strategies for implementation and acceptance of these early warning systems for clinical use in obstetrics. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available BACKGROUND: Multiple sclerosis (MS is a demyelinating and neuroinflammatory disease of the human central nervous system (CNS. The expression of kinins is increased in MS patients, but the underlying mechanisms by which the kinin receptor regulates MS development have not been elucidated. METHODOLOGY/PRINCIPAL FINDINGS: Experimental autoimmune encephalomyelitis (EAE was induced in female C57BL/6 mice by immunization with MOG(35-55 peptide emulsified in complete Freund's adjuvant and injected with pertussis toxin on day 0 and day 2. Here, we report that blockade of the B(1R in the induction phase of EAE markedly suppressed its progression by interfering with the onset of the immune response. Furthermore, B(1R antagonist suppressed the production/expression of antigen-specific T(H1 and T(H17 cytokines and transcription factors, both in the periphery and in the CNS. In the chronic phase of EAE, the blockade of B(1R consistently impaired the clinical progression of EAE. Conversely, administration of the B(1R agonist in the acute phase of EAE suppressed disease progression and inhibited the increase in permeability of the blood-brain barrier (BBB and any further CNS inflammation. Of note, blockade of the B(2R only showed a moderate impact on all of the studied parameters of EAE progression. CONCLUSIONS/SIGNIFICANCE: Our results strongly suggest that kinin receptors, mainly the B(1R subtype, play a dual role in EAE progression depending on the phase of treatment through the lymphocytes and glial cell-dependent pathways.

    Many preschool children develop recurrent, severe episodes of lower respiratory tract illness (LRTI). Although viral infections are often present, bacteria may also contribute to illness pathogenesis. Strategies that effectively attenuate such episodes are needed. To evaluate if early administration of azithromycin, started prior to the onset of severe LRTI symptoms, in preschool children with recurrent severe LRTIs can prevent the progression of these episodes. A randomized, double-blind, placebo-controlled, parallel-group trial conducted across 9 academic US medical centers in the National Heart, Lung, and Blood Institute's AsthmaNet network, with enrollment starting in April 2011 and follow-up complete by December 2014. Participants were 607 children aged 12 through 71 months with histories of recurrent, severe LRTIs and minimal day-to-day impairment. Participants were randomly assigned to receive azithromycin (12 mg/kg/d for 5 days; n = 307) or matching placebo (n = 300), started early during each predefined RTI (child's signs or symptoms prior to development of LRTI), based on individualized action plans, over a 12- through 18-month period. The primary outcome measure was the number of RTIs not progressing to a severe LRTI, measured at the level of the RTI, that would in clinical practice trigger the prescription of oral corticosteroids. Presence of azithromycin-resistant organisms in oropharyngeal samples, along with adverse events, were among the secondary outcome measures. A total of 937 treated RTIs (azithromycin group, 473; placebo group, 464) were experienced by 443 children (azithromycin group, 223; placebo group, 220), including 92 severe LRTIs (azithromycin group, 35; placebo group, 57). Azithromycin significantly reduced the risk of progressing to severe LRTI relative to placebo (hazard ratio, 0.64 [95% CI, 0.41-0.98], P = .04; absolute risk for first RTI: 0.05 for azithromycin, 0.08 for placebo; risk difference, 0.03 [95% CI, 0

    2015-03-01

    Severe, long-lasting influenza infections are often caused by new strains of influenza. The long duration of these infections leads to an increased opportunity for the emergence of drug resistant mutants. This is particularly problematic for new strains of influenza since there is often no vaccine, so drug treatment is the first line of defense. One strategy for trying to minimize drug resistance is to apply periodic treatment. During treatment the wild-type virus decreases, but resistant virus might increase; when there is no treatment, wild-type virus will hopefully out-compete the resistant virus, driving down the number of resistant virus. We combine a mathematical model of severe influenza with a model of drug resistance to study emergence of drug resistance during a long-lasting infection. We apply periodic treatment with two types of antivirals: neuraminidase inhibitors, which block release of virions; and adamantanes, which block replication of virions. We compare the efficacy of the two drugs in reducing emergence of drug resistant mutants and examine the effect of treatment frequency on the emergence of drug resistant mutants.

    Since low basal metabolic rate (BMR) is a risk factor for weight regain, it is important to measure BMR before bariatric surgery. We aimed to evaluate the BMR among clinically severe obese patients preoperatively. We compared it with that of the control group, with predictive formulas and correlated it with body composition. We used indirect calorimetry (IC) to collect BMR data and multifrequency bioelectrical impedance to collect body composition data. Our sample population consisted of 193 patients of whom 130 were clinically severe obese and 63 were normal/overweight individuals. BMR results were compared with the following predictive formulas: Harris-Benedict (HBE), Bobbioni-Harsch (BH), Cunningham (CUN), Mifflin-St. Jeor (MSJE), and Horie-Waitzberg & Gonzalez (HW & G). This study was approved by the Ethics Committee for Research of the University of Brasilia. Statistical analysis was used to compare and correlate variables. Clinically severe obese patients had higher absolute BMR values and lower adjusted BMR values (p BMR were found in both groups. Among the clinically severe obese patients, the formulas of HW & G and HBE overestimated BMR values (p = 0.0002 and p = 0.0193, respectively), while the BH and CUN underestimated this value; only the MSJE formulas showed similar results to those of IC. The clinically severe obese patients showed low BMR levels when adjusted per kilogram per body weight. Body composition may influence BMR. The use of the MSJE formula may be helpful in those cases where it is impossible to use IC.

    Full Text Available Severe liver diseases such as liver failure and acute decompensated cirrhosis have critical conditions and high mortality rates, and the prognosis of such patients is closely associated with early warning, timely dynamic assessment, and comprehensive and effective therapy. The patients require a series of effective clinical management measures for elimination of causative factors, organ support, and prevention and treatment of complications. Medical treatment-artificial liver-liver transplantation is an important modality for severe liver diseases. Granulocyte colony-stimulating factor, stem cell therapy, and bioartificial liver have a promising future, while there are still controversies over non-selective β-blocker. This article reviews the hotspots in the clinical management of severe liver diseases.

    This article seeks to advance ethical dialogue on choosing standards of prevention in clinical trials testing improved biomedical prevention methods for HIV. The stakes in this area of research are high, given the continued high rates of infection in many countries and the budget limitations that have constrained efforts to expand treatment for all who are currently HIV-infected. New prevention methods are still needed; at the same time, some existing prevention and treatment interventions have been proven effective but are not yet widely available in the countries where they most urgently needed. The ethical tensions in this field of clinical research are well known and have been the subject of extensive debate. There is no single clinical trial design that can optimize all the ethically important goals and commitments involved in research. Several recent articles have described the current ethical difficulties in designing HIV prevention trials, especially in resource limited settings; however, there is no consensus on how to handle clinical trial design decisions, and existing international ethical guidelines offer conflicting advice. This article acknowledges these deep ethical dilemmas and moves beyond a simple descriptive approach to advance an organized method for considering what clinical trial designs will be ethically acceptable for HIV prevention trials, balancing the relevant criteria and providing justification for specific design decisions.

    The dramatic increase in breast cancer incidence compels a paradigm shift in our preventive efforts. There are several barriers to overcome before prevention becomes an established part of breast cancer management. The objective of this review is to identify the clinical challenges for improved breast cancer prevention and discuss current knowledge on breast cancer risk assessment methods, risk communication, ethics, and interventional efforts with the aim of covering the aspects relevant for a breast cancer prevention trial. Herein, the following five areas are discussed: (i) Adequate tools for identification of women at high risk of breast cancer suggestively entitled Prevent! Online. (ii) Consensus on the definition of high risk, which is regarded as mandatory for all risk communication and potential prophylactic interventions. (iii) Risk perception and communication regarding risk information. (iv) Potential ethical concerns relevant for future breast cancer prevention programs. (v) Risk-reducing programs involving multileveled prevention depending on identified risk. Taken together, devoted efforts from both policy makers and health care providers are warranted to improve risk assessment and risk counseling in women at risk for breast cancer to optimize the prevention of breast cancer.

    An important goal of the US DOE reactor development program is to conceptualize advanced safety design features for a demonstration Sodium Fast Reactor (SFR). The treatment of severe accidents is one of the key safety issues in the design approach for advanced SFR systems. It is necessary to develop an in-depth understanding of the risk of severe accidents for the SFR so that appropriate risk management measures can be implemented early in the design process. This report presents the results of a review of the SFR features and phenomena that directly influence the sequence of events during a postulated severe accident. The report identifies the safety features used or proposed for various SFR designs in the US and worldwide for the prevention and/or mitigation of Core Disruptive Accidents (CDA). The report provides an overview of the current SFR safety approaches and the role of severe accidents. Mutual understanding of these design features and safety approaches is necessary for future collaborations between the US and its international partners as part of the GEN IV program. The report also reviews the basis for an integrated safety approach to severe accidents for the SFR that reflects the safety design knowledge gained in the US during the Advanced Liquid Metal Reactor (ALMR) and Integral Fast Reactor (IFR) programs. This approach relies on inherent reactor and plant safety performance characteristics to provide additional safety margins. The goal of this approach is to prevent development of severe accident conditions, even in the event of initiators with safety system failures previously recognized to lead directly to reactor damage.

  1. Prevention of heavy missiles during severe PWR accidents

    For future pressurized water reactors, which should be designed against core melt down accidents, missiles generated inside the containment present a severe problem for its integrity. The masses and geometries of the missiles as well as their velocities may vary to a great extend. Therefore, a reliable proof of the containment integrity is very difficult. To overcome this problem the potential sources of missiles are discussed. In section 5 it is concluded that the generation of heavy missiles must be prevented. Steam explosions must not damage the reactor vessel head. Thus fragments of the head cannot become missiles endangering the containment shell. Furthermore, during a melt-through failure of the reactor vessel under high pressure the resulting forces must not catapult the whole vessel against the containment shell. Only missiles caused by hydrogen explosions might be tolerable, but shielding structures which protect the containment shell might be required. Here further investigations are necessary. Finally, measures are described showing that the generation of heavy missiles can indeed be prevented. In section 6 investigations are explained which will confirm the strength of the reactor vessel head. In section 7 a device is discussed keeping the fragments of a failing reactor vessel at its place. (author). 12 refs., 8 figs

  2. Enhanced Severe Transient Analysis for Prevention Technical Program Plan

    2014-09-01

    This document outlines the development of a high fidelity, best estimate nuclear power plant severe transient simulation capability that will complement or enhance the integral system codes historically used for licensing and analysis of severe accidents. As with other tools in the Risk Informed Safety Margin Characterization (RISMC) Toolkit, the ultimate user of Enhanced Severe Transient Analysis and Prevention (ESTAP) capability is the plant decision-maker; the deliverable to that customer is a modern, simulation-based safety analysis capability, applicable to a much broader class of safety issues than is traditional Light Water Reactor (LWR) licensing analysis. Currently, the RISMC pathway’s major emphasis is placed on developing RELAP-7, a next-generation safety analysis code, and on showing how to use RELAP-7 to analyze margin from a modern point of view: that is, by characterizing margin in terms of the probabilistic spectra of the “loads” applied to systems, structures, and components (SSCs), and the “capacity” of those SSCs to resist those loads without failing. The first objective of the ESTAP task, and the focus of one task of this effort, is to augment RELAP-7 analyses with user-selected multi-dimensional, multi-phase models of specific plant components to simulate complex phenomena that may lead to, or exacerbate, severe transients and core damage. Such phenomena include: coolant crossflow between PWR assemblies during a severe reactivity transient, stratified single or two-phase coolant flow in primary coolant piping, inhomogeneous mixing of emergency coolant water or boric acid with hot primary coolant, and water hammer. These are well-documented phenomena associated with plant transients but that are generally not captured in system codes. They are, however, generally limited to specific components, structures, and operating conditions. The second ESTAP task is to similarly augment a severe (post-core damage) accident integral analyses code

    During the past two decades PCR and several other DNA/RNA amplification techniques have become important diagnostic tools in clinical laboratories. Amplification products contamination has been the main impediment to using these techniques routinely in diagnostic laboratories. Over the years, several creative pre- and post-amplification methods have been developed that prevent amplicon carryover contamination. These procedures, coupled with automated systems that employ real-time amplification and simultaneous detection in a closed system, have substantially reduced the possibility of false positive results due to amplification products carryover contamination.

The prevalence and burden of severe COPD exacerbations remain high, despite recognition of the importance of exacerbation prevention and the availability of new treatment options. Severe COPD exacerbations are associated with high mortality, have negative impact on quality of life, are linked to cardiovascular complications, and are a significant burden on the health-care system. This review identified risk factors that contribute to the development of severe exacerbations, treatment options (bronchodilators, antibiotics, corticosteroids [CSs], oxygen therapy, and ventilator support to manage severe exacerbations, and strategies to prevent readmission to hospital. Risk factors that are amenable to change have been highlighted. A number of bronchodilators have demonstrated successful reduction in risk of severe exacerbations, including long-acting muscarinic antagonist or long-acting β2-agonist mono- or combination therapies, in addition to vaccination, mucolytic and antibiotic therapy, and nonpharmacological interventions, such as pulmonary rehabilitation. Recognition of the importance of severe exacerbations is an essential step in improving outcomes for patients with COPD. Evidence-based approaches to prevent and manage severe exacerbations should be implemented as part of targeted strategies for disease management. Keywords

    Full Text Available Currently, several assays can confirm acute dengue infection at the point-of-care. However, none of these assays can predict the severity of the disease symptoms. A prognosis test that predicts the likelihood of a dengue patient to develop a severe form of the disease could permit more efficient patient triage and treatment. We hypothesise that mRNA expression of apoptosis and innate immune response-related genes will be differentially regulated during the early stages of dengue and might predict the clinical outcome. Aiming to identify biomarkers for dengue prognosis, we extracted mRNA from the peripheral blood mononuclear cells of mild and severe dengue patients during the febrile stage of the disease to measure the expression levels of selected genes by quantitative polymerase chain reaction. The selected candidate biomarkers were previously identified by our group as differentially expressed in microarray studies. We verified that the mRNA coding for CFD, MAGED1, PSMB9, PRDX4 and FCGR3B were differentially expressed between patients who developed clinical symptoms associated with the mild type of dengue and patients who showed clinical symptoms associated with severe dengue. We suggest that this gene expression panel could putatively serve as biomarkers for the clinical prognosis of dengue haemorrhagic fever.

    Dengue fever is one of the most important emerging vector-borne viral diseases. Approximately 500,000 out of 100 million cases develop to severe dengue infection. Patient with severe dengue (SD) can be predicted by clinical profile, laboratory and warning sign which could be saved by early interventions.This was a retrospective descriptive-analytic study to investigate clinical manifestations, laboratory and warning signs ofchildren with dengue infection in Haji Adam Malik hospital during January 2014–May 2016. Through medical records, we had selected 140 cases which fulfilled research criteria.Cases were classified as SD (n=28) and NSD (n=112). Most common clinical manifestations for NSD were abdominal pain (39.3%), myalgia (39.3%), headache (37.1%), mucosal bleeding (36.4%) while for SD were shock (15.7%), mucosal bleeding (15.7%), clinical fluid accumulation (15%), shortness of breath (14.3%). SGPT >1000IU/L (5 cases), SGOT >1000IU/L (9 cases), PT (10 cases) and aPTT (16 cases) were abnormal in SD. Severe dengue was frequently found in the range of white cell count 1000-4000/L and platelet count 20,000-50,000mm/uL. Clinical manifestations, warning sign, and laboratoryfinding, were different between SD and NSD.

  12. Prevention of epilepsy: Should we be avoiding clinical trials?

    Science.gov (United States)

    Klein, Pavel; Tyrlikova, Ivana

    2017-07-01

    Epilepsy prevention is one of the great unmet needs in epilepsy. Approximately 15% of all epilepsy is caused by an acute acquired CNS insult such as traumatic brain injury (TBI), stroke or encephalitis. There is a latent period between the insult and epilepsy onset that presents an opportunity to intervene with preventive treatment that is unique in neurology. Yet no phase 3 epilepsy prevention studies, and only 2 phase 2 studies have been initiated in the last 16years. Current prevailing opinion is that the research community is not ready for clinical preventive epilepsy studies, and that animal models should first be refined and biomarkers of epileptogenesis and of epilepsy discovered before clinical studies are embarked upon. We review data to suggest that there is basis to do epilepsy prevention studies now with the current knowledge and available drugs, and that those studies are feasible with currently available tools. We suggest that a different approach is needed from the past in order to maximize chances of success, minimize the cost, and set up platform for future preventive treatment development. That approach should include close coordination of preclinical and clinical development programs in a combined PTE prevention strategy, consideration of polytherapy, and simultaneous, combined clinical development of preventive treatment and of biomarker discovery. We argue that the currently favored approach of eschewing clinical studies until biomarkers are available will delay the discovery of epilepsy prevention treatment by at least 10 years and significantly increase the cost of such discovery.

    This study examines the clinical course of restless legs syndrome according to its severity and factors associated with the remission of restless legs syndrome symptoms. The remission or persistence of restless legs syndrome symptoms was investigated by considering patients with restless legs syndrome at the sleep clinic of Seoul National University Bundang Hospital. All subjects were observed for at least 18 months, and an incidence of remission was defined as having no restless legs syndrome symptoms for at least 1 year. Restless legs syndrome severity was evaluated by the International Restless Legs Syndrome Study Group Rating Scale. A total of 306 patients participated in this study. Over the observation periods of 4.1 ± 1.6 years, the cumulative incidence of remission is 32.5% (95% confidence interval [CI], 27.0-38.0) and decreased with baseline restless legs syndrome severity (P restless legs syndrome cases, respectively. Most cases of remission (82/96) were observed within 1 year, and the remission occurred sooner for mild restless legs syndrome. The hazard ratios of remission by Cox proportional hazards model were lower for moderate (0.556; 95% CI, 0.340-0.909) and severe to very severe (0.193; 95% CI, 0.108-0.343) restless legs syndrome than for mild restless legs syndrome. The remission incidence was lower for those patients who had a family history of restless legs syndrome and were older at restless legs syndrome diagnosis. Mild restless legs syndrome severity, no family history, and young age at restless legs syndrome diagnosis were significant predictors of restless legs syndrome remission. More than 80% of patients with severe restless legs syndrome showed a chronic clinical course. Copyright © 2016 Elsevier Inc. All rights reserved.

    Alzheimer's disease (AD) is a major source of morbidity and mortality, with the disease burden expected to rise as the population ages. No disease-modifying agent is currently available, but recent research suggests that nutritional and lifestyle modifications can delay or prevent the onset of AD. However, preventive nutritional interventions are not universally applicable and depend on the clinical profile of the individual patient. This article reviews existing nutritional modalities for AD prevention that act through improvement of insulin resistance, correction of dyslipidemia, and reduction of oxidative stress, and discusses how they may be modified on the basis of individual biomarkers, genetics, and behavior. In addition, we report preliminary results of clinical application of these personalized interventions at the first AD prevention clinic in the United States. The use of these personalized interventions represents an important application of precision medicine techniques for the prevention of AD that can be adopted by clinicians across disciplines. © 2016 New York Academy of Sciences.

    The degree of agreement between patient- and clinician-rated scales of depressive severity varies widely. This study analyzed agreement between commonly used depression rating scales in the Prevention of Recurrent Episodes of Depression with Venlafaxine Extended Release (ER) for Two Years (PREVENT) trial. The PREVENT trial was a multiphase, randomized, double-blind study of patients with recurrent major depressive disorder. This secondary analysis evaluated acute (10weeks) and continuation phase (6months) data. Pearson correlation coefficients at each acute-phase (weekly) and continuation-phase (monthly) visit were calculated for patient-rated (30-item Inventory of Depressive Symptomatology-Self-Rated [IDS-SR30] and clinician-rated (17-item Hamilton Rating Scale for Depression [HAM-D17] and Clinical Global Impressions-Severity [CGI-S]) measures and for response and remission. Data from 1,047 patients were analyzed. The respective correlation coefficients at baseline, week 10, and month 6 were: IDS-SR30: HAM-D17: 0.46, 0.75, 0.70; and for IDS-SR30: CGI-S 0.28, 0.67, 0.65. Agreement between IDS-SR30- and HAM-D17-defined remission and response was relatively poor: week 10, 0.52 and 0.34, respectively; month 6, 0.45 and 0.32, respectively. These findings suggest that patient-rated measures of depression severity do not correspond strongly with clinician ratings, and are particularly poor prior to the initiation of treatment.

    Fibromyalgia (FM) is a rheumatic condition characterized by a picture of generalized chronic pain, hyperalgesia and allodynia. Symptoms such as fatigue, sleep disorders, morning stiffness, headache and paresthesia can also be present. It is also associated with other comorbidities, such as depression, anxiety, irritable bowel syndrome, myofascial pain syndrome and nonspecific urethral syndrome. Few studies have addressed the evolution of FM, especially regarding medium and long-term evolution, such as why some patients do better than others, despite the fact of being submitted to the same treatment. To determine whether there is a correlation between demographic and clinical variables and FM severity. Sixty women who met the classification criteria for FM of the American College of Rheumatology of 1990 were divided into three groups, according to the severity established by the Fibromyalgia Impact Questionnaire (FIQ): severe (70-100), moderate (50 to 70) and mild (0 to 50). Nine demographic and clinical variables were assessed, with a significant difference (P <0.05) being observed only in the groups showing higher FIQ scores with the presence of depression and workers' compensation interests. The impact of FM measured by the FIQ is directly correlated with the severity of depression and the presence of workers' compensation interests.

    Clinical trials in severe falciparum malaria require a large sample size to detect clinically meaningful differences in mortality. This means few interventions can be evaluated at any time. Using a validated surrogate endpoint for mortality would provide a useful alternative allowing a smaller sample size. Here we evaluate changes in coma score and plasma lactate as surrogate endpoints for mortality in severe falciparum malaria. Three datasets of clinical studies in severe malaria were re-evaluated: studies from Chittagong, Bangladesh (adults), the African 'AQUAMAT' trial comparing artesunate and quinine (children), and the Vietnamese 'AQ' study (adults) comparing artemether with quinine. The absolute change, relative change, slope of the normalization over time, and time to normalization were derived from sequential measurements of plasma lactate and coma score, and validated for their use as surrogate endpoint, including the proportion of treatment effect on mortality explained (PTE) by these surrogate measures. Improvements in lactate concentration or coma scores over the first 24 hours of admission, were strongly prognostic for survival in all datasets. In hyperlactataemic patients in the AQ study (n = 173), lower mortality with artemether compared to quinine closely correlated with faster reduction in plasma lactate concentration, with a high PTE of the relative change in plasma lactate at 8 and 12 hours of 0.81 and 0.75, respectively. In paediatric patients enrolled in the 'AQUAMAT' study with cerebral malaria (n = 785), mortality was lower with artesunate compared to quinine, but this was not associated with faster coma recovery. The relative changes in plasma lactate concentration assessed at 8 or 12 hours after admission are valid surrogate endpoints for severe malaria studies on antimalarial drugs or adjuvant treatments aiming at improving the microcirculation. Measures of coma recovery are not valid surrogate endpoints for mortality.

    Background : Pneumonia is a major complication of influenza that contributes to mortality. Clinical characteristics and factors of influenza virus contributing to the severity and mortality of pneumonia have not been fully elucidated. Objective : The objective was to clarify clinical characteristics and factors contributing to the severity and mortality of influenza-associated pneumonia ( flu-p ). Methods : We retrospectively analyzed patients with flu-p . Results : From December 1999 to March 2016, 210 patients with a median age of 69 (range, 17 to 92) years with flu-p based on positive rapid antigen tests, increased antibody titers of paired sera, or positive results of reverse transcription polymerase chain reaction were admitted to our institution. A multivariate analysis found that advanced age (≥ 65 years), pneumonia subtypes (unclassified), diabetes mellitus, and acute kidney injury complicated with flu-p were independent factors associated with disease severity, whereas pneumonia subtypes (mixed viral and bacterial pneumonia and unclassified), healthcare-associated pneumonia, acute kidney injury complicated with flu-p , and severity on admission (severe) were independent factors associated with non-survival. Conclusion : The clinical characteristics of flu-p are varied, and the contribution of several factors to the severity and mortality of flu-p suggest their importance in either preventing flu-p or managing flu-p after it develops.

    Full Text Available AIM: To analyze the clinical features of children ocular penetrating trauma, and hope to effectively assist to prevent pediatric ocular traumaMETHODS: The data of 145 cases(145 eyeswith ocular penetrating trauma, hospitalized in Xijing Hospital from January 2012 to December 2016, were collected and retrospectively analyzed. All the data of injury factors and environment, age and gender of patients, lesions, treatment and prognosis were detailed studied.RESULTS: In all the 145 pediatric patients with ocular penetrating trauma, accounted for 8.5% of all the ocular trauma patients, there were 95 cases of male, and 50 of female. Penetrating injuries mainly occurred in age of 3-9. The main injuries of ocular perforating in children were scissors, and sharp objects of wooden and iron. The wound was often located in the cornea or the anterior sclera. Traumatic cataract, vitreous hemorrhage and endophthalmitis were the common complications. The visual acuity was severely damaged, and 90 cases(62.1%of the children recovered better than 0.1 after effective treatment.CONCLUSION: The visual function of pediatric p0atients was seriously threatened after penetrating injuries. However, the damage of vision and the rate of blindness can be reduced effectively after timely and correct diagnosis and treatment. It is the most important that active and effective prevention in keep children away from penetrating injuries.

    Full Text Available Bruce Parsons,1 Charles E Argoff,2 Andrew Clair,1 Birol Emir1 1Pfizer, New York, NY, USA; 2Albany Medical Center, Albany, NY, USA Background: Pregabalin is approved by the US Food and Drug Administration for the treatment of fibromyalgia (FM, diabetic peripheral neuropathy (DPN, postherpetic neuralgia (PHN, and neuropathic pain due to spinal cord injury (SCI. Approval was based on clinical trial data demonstrating statistically significant differences in pain scores versus placebo. However, statistically significant pain relief may not always equate to clinically meaningful pain relief. To further characterize the clinical benefit of pregabalin, this analysis examined shifts in pain severity categories in patients with FM, DPN/PHN (pooled in this analysis, and SCI treated with pregabalin.Methods: Data were pooled from 23 placebo-controlled trials in patients with FM (1,623 treated with pregabalin, 937 placebo, DPN/PHN (2,867 pregabalin, 1,532 placebo, or SCI (181 pregabalin, 175 placebo. Pain scores were assessed on an 11-point numeric rating scale and categorized as mild (0 to <4, moderate (4 to <7, or severe (7 to 10. Only patients with mean score ≥4 at baseline were randomized to treatment. The percentage of patients shifting pain category from baseline to endpoint for pregabalin and placebo was analyzed using a modified ridit transformation with the Cochran–Mantel–Haenszel procedure.Results: A higher proportion of patients shifted to a less severe pain category at endpoint with pregabalin compared with placebo. With flexible-dose pregabalin, the percentage of patients improving from: severe to mild (pregabalin versus placebo was 15.8 versus 13.4 in FM patients, 36.0 versus 16.6 in DPN/PHN patients, 14.3 versus 7.7 in SCI patients; severe to moderate was 28.7 versus 28.2 in FM patients, 32.5 versus 28.2 in DPN/PHN patients, 35.7 versus 28.2 in SCI patients; and moderate to mild was 38.3 versus 26.4 in FM patients, 59.5 versus 41.4 in

    Patients with severe asthma represent a minority of the total asthma population, but carry a majority of the morbidity and healthcare costs. Achieving better asthma control in this group of patients is therefore of key importance. Systematic assessment of patients with possible severe asthma to identify treatment barriers and triggers of asthma symptoms, including co-morbidities, improves asthma control and reduces healthcare costs and is recommended by international guidelines on management of severe asthma. This review provides the clinician with an overview of the prevalence and clinical impact of the most common co-morbidities in severe asthma, including chronic rhinosinusitis, nasal polyposis, allergic rhinitis, dysfunctional breathing, vocal cord dysfunction, anxiety and depression, obesity, obstructive sleep apnoea syndrome (OSAS), gastroesophageal reflux disease (GERD), bronchiectasis, allergic bronchopulmonary aspergillosis (ABPA) and eosinophilic granulomatous with polyangiitis (EGPA). Furthermore, the review offers a summary of recommended diagnostic and management approaches for each co-morbidity. Finally, the review links co-morbid conditions to specific phenotypes of severe asthma, in order to guide the clinician on which co-morbidities to look for in specific patients. © 2017 Asian Pacific Society of Respirology.

    Mood disorders, including major depressive disorder (MDD) and bipolar disorder (BD), are highly prevalent, frequently disabling, and sometimes deadly. Additional research and more effective medications are desperately needed, but clinical trials research in mood disorders is fraught with ethical issues. Although many authors have discussed these issues, most do so from a theoretical viewpoint. This manuscript uses available empirical data to inform a discussion of the primary ethical issues raised in mood disorders research. These include issues of consent and decision-making capacity, including patients' motivations for participating in research. We also address drug withdrawals, placebo controls, and the overall safety of research. Finally, we examine the extant literature for studies discussing potential indirect benefits of clinical trials research to participants. Taken together, the evidence suggests that clinical trials research incorporating drug withdrawals and placebo controls can be conducted safely and ethically, even in patients with severe or treatment-resistant mood disorders. In fact, given the dearth of effective treatment options for this population, it is our opinion that a moral imperative exists to extend the offer of research participation to severely ill or treatment-resistant groups.

    2013-08-20

    The 2010 Patient Protection and Affordable Care Act provides incentives for both patients and providers to engage in evidence-based clinical preventive services recommended by the United States Preventive Services Task Force (USPSTF). Depending upon the application of the new health care act, Doctors of Chiropractic (DC) may be considered to be covered providers of many of these services. It is therefore essential that DCs' training prepare them to competently deliver them. The aim of this commentary is to describe a framework for training in clinical preventive services, based largely on the USPSTF recommendations, which could be readily integrated into existing DC educational programs.

    Paulo Rogério Borges Rosmaninho Varandas

    Full Text Available Abstract Today, Alzheimer disease has become a serious risk to individual and public health, due to the significant incapacity it causes patients, its influence on family members and caregivers, along with the ensuing direct and indirect costs. Objectives: To build the profile of patients with moderate/severe AD, in the Geriatric Clinic Service of Cognitive Alterations of the Medical School at Universidade de São Paulo, by studying demential and comorbidity conditions and the degree of effectiveness of the therapies applied. Methods: 30 patients with moderate or severe AD were selected, (77.8±7.29 years. Age, sex, schooling, prevalent comorbidities/treatments and respective clinical-laboratorial effectiveness were analyzed. Instruments were applied to evaluate the cognitive and behavioral condition and dementia control therapies. Results: Most frequent comorbidities were arterial hypertension (80% and diabetes (43.3%. A maximum dose of rivastigmine was observed in 43% of the patients, where 76% experienced adverse effects. Severe patients presented more cases of uncontrolled comorbidities, such as hypertension (P<0.001, as well as more behavioral alterations (P<0.001 and functional loss (P=0.004. Patients with greater behavioral alterations proved to be more functionally dependent (P=0.002, having less comorbidity control (P=0.004. Conclusions: In this population, a high incidence of comorbidities, frequent behavioral alterations and difficulties in therapy management were noted due to the severity of the dementia condition. New therapies for more adequate control of severe dementia should be studied.

  7. Differentiating clinical care from disease prevention: a prerequisite for practicing quaternary prevention

    Directory of Open Access Journals (Sweden)

    Charles Dalcanale Tesser

    Full Text Available Abstract: This article contends that the distinction between clinical care (illness and prevention of future disease is essential to the practice of quaternary prevention. The authors argue that the ongoing entanglement of clinical care and prevention transforms healthy into "sick" people through changes in disease classification criteria and/or cut-off points for defining high-risk states. This diverts health care resources away from those in need of care and increases the risk of iatrogenic harm in healthy people. The distinction in focus is based on: (a management of uncertainty (more flexible when caring for ill persons; (b guarantee of benefit (required only in prevention; (c harm tolerance (nil or minimal in prevention. This implies attitudinal differences in the decision-making process: greater skepticism, scientism and resistance towards preventive action. These should be based on high-quality scientific evidence of end-outcomes that displays a net positive harm/benefit ratio.

    The genetically diverse viridans group streptococci (VGS) are increasingly recognized as the cause of a variety of human diseases. We used a recently developed multilocus sequence analysis scheme to define the species of 118 unique VGS strains causing bacteremia in patients with cancer; Streptococcus mitis (68 patients) and S. oralis (22 patients) were the most frequently identified strains. Compared with patients infected with non–S. mitis strains, patients infected with S. mitis strains were more likely to have moderate or severe clinical disease (e.g., VGS shock syndrome). Combined with the sequence data, whole-genome analyses showed that S. mitis strains may more precisely be considered as >2 species. Furthermore, we found that multiple S. mitis strains induced disease in neutropenic mice in a dose-dependent fashion. Our data define the prominent clinical effect of the group of organisms currently classified as S. mitis and lay the groundwork for increased understanding of this understudied pathogen.

    Paraquat is a nonselective contact herbicide of great toxicological importance, being associated with high mortality rates, mainly due to respiratory failure. We report the case of a 22-year-old male admitted to the emergency room with a sore throat, dysphagia, hemoptysis, and retrosternal pain after the ingestion of 50 mL of a paraquat solution, four days prior to admission. Chest CT scans revealed pulmonary opacities, pneumomediastinum, pneumothorax, and subcutaneous emphysema. The patient was submitted to two cycles of immunosuppressive therapy with cyclophosphamide, methylprednisolone, and dexamethasone. The pulmonary gas exchange parameters gradually improved, and the patient was discharged four weeks later. The clinical and tomographic follow-up evaluations performed at four months after discharge showed that there had been further clinical improvement. We also present a brief review of the literature, as well as a discussion of the therapeutic algorithm for severe paraquat poisoning. (author)

    Clinicians caring for patients infected with Ebola virus must be familiar not only with screening and infection control measures but also with management of severe disease. By integrating experience from several Ebola epidemics with best practices for managing critical illness, this report focuses on the clinical presentation and management of severely ill infants, children, and adults with Ebola virus disease. Fever, fatigue, vomiting, diarrhea, and anorexia are the most common symptoms of the 2014 West African outbreak. Profound fluid losses from the gastrointestinal tract result in volume depletion, metabolic abnormalities (including hyponatremia, hypokalemia, and hypocalcemia), shock, and organ failure. Overt hemorrhage occurs infrequently. The case fatality rate in West Africa is at least 70%, and individuals with respiratory, neurological, or hemorrhagic symptoms have a higher risk of death. There is no proven antiviral agent to treat Ebola virus disease, although several experimental treatments may be considered. Even in the absence of antiviral therapies, intensive supportive care has the potential to markedly blunt the high case fatality rate reported to date. Optimal treatment requires conscientious correction of fluid and electrolyte losses. Additional management considerations include searching for coinfection or superinfection; treatment of shock (with intravenous fluids and vasoactive agents), acute kidney injury (with renal replacement therapy), and respiratory failure (with invasive mechanical ventilation); provision of nutrition support, pain and anxiety control, and psychosocial support; and the use of strategies to reduce complications of critical illness. Cardiopulmonary resuscitation may be appropriate in certain circumstances, but extracorporeal life support is not advised. Among other ethical issues, patients' medical needs must be carefully weighed against healthcare worker safety and infection control concerns. However, meticulous attention

    Becker muscular dystrophy (BMD) is characterised by broad clinical variability. Ongoing studies exploring dystrophin restoration in Duchenne muscular dystrophy ask for better understanding of the relation between dystrophin levels and disease severity. We studied this relation in BMD patients with varying mutations, including a large subset with an exon 45-47 deletion. Dystrophin was quantified by western blot analyses in a fresh muscle biopsy of the anterior tibial muscle. Disease severity was assessed using quantitative muscle strength measurements and functional disability scoring. MRI of the leg was performed in a subgroup to detect fatty infiltration. 33 BMD patients participated. No linear relation was found between dystrophin levels (range 3%-78%) and muscle strength or age at different disease milestones, in both the whole group and the subgroup of exon 45-47 deleted patients. However, patients with less than 10% dystrophin all showed a severe disease course. No relation was found between disease severity and age when analysing the whole group. By contrast, in the exon 45-47 deleted subgroup, muscle strength and levels of fatty infiltration were significantly correlated with patients' age. Our study shows that dystrophin levels appear not to be a major determinant of disease severity in BMD, as long as it is above approximately 10%. A significant relation between age and disease course was only found in the exon 45-47 deletion subgroup. This suggests that at higher dystrophin levels, the disease course depends more on the mutation site than on the amount of the dystrophin protein produced.

The purpose of this study is to evaluate the clinical course and severity of MMD in pediatric patients. Material and Method: We examined 5 consecutive pediatric patients with MMD, focusing on clinical and radiological features, the therapy and outcome over the 58-month follow-up period. Results: The study population consisted of 3 boys and 2 girls. The mean age at diagnosis of patients was 7.2 ± 3.4 years (age range: 3-10 years. The mean duration of follow-up was 30.4 ± 17.4 months (follow-up interval: 12-58 months. Neurological findings at presentation included: motor deficit in 4 patients (80.0%, epileptic seizures in 2 patients (40.0%, movement disorders in 3 patients (60.0%, and headache in 1 patients (20.0%. There was areas of infarction on brain MRI in all patients. Angiographic findings included: internal carotid artery stenosis in all patients, anterior cerebral artery stenosis in 3 patients, middle cerebral artery stenosis in 3 patients, posterior cerebral artery stenosis in 2 patients, and vertebral artery stenosis in 1 patient. Enoxaparine therapy was started to all patients. Subdural hematoma developed in 1 patient during follow-up. Cerebral infarctions recurred despite medical treatment in 4 patients. Discussion: Although this disease is rare, it is an important cause of pediatric stroke. MMD shows different clinical course and disease severity in childhood. Early diagnosis and appropriate treatment are crucial.

    Although certain risk factors can identify individuals who are most likely to develop chronic pain, few interventions to prevent chronic pain have been identified. To facilitate the identification of preventive interventions, an IMMPACT meeting was convened to discuss research design considerations...... for clinical trials investigating the prevention of chronic pain. We present general design considerations for prevention trials in populations that are at relatively high risk for developing chronic pain. Specific design considerations included subject identification, timing and duration of treatment...... element exposure), and are chronically painful conditions that are treated with a range of interventions. Improvements in the design of chronic pain prevention trials could improve assay sensitivity and thus accelerate the identification of efficacious interventions. Such interventions would have...

  17. Osteogenesis imperfecta: clinical diagnosis, nomenclature and severity assessment.

    Science.gov (United States)

    Van Dijk, F S; Sillence, D O

    2014-06-01

    Recently, the genetic heterogeneity in osteogenesis imperfecta (OI), proposed in 1979 by Sillence et al., has been confirmed with molecular genetic studies. At present, 17 genetic causes of OI and closely related disorders have been identified and it is expected that more will follow. Unlike most reviews that have been published in the last decade on the genetic causes and biochemical processes leading to OI, this review focuses on the clinical classification of OI and elaborates on the newly proposed OI classification from 2010, which returned to a descriptive and numerical grouping of five OI syndromic groups. The new OI nomenclature and the pre-and postnatal severity assessment introduced in this review, emphasize the importance of phenotyping in order to diagnose, classify, and assess severity of OI. This will provide patients and their families with insight into the probable course of the disorder and it will allow physicians to evaluate the effect of therapy. A careful clinical description in combination with knowledge of the specific molecular genetic cause is the starting point for development and assessment of therapy in patients with heritable disorders including OI. © 2014 The Authors.

    1982-01-01

    Serial computerized tomography (SCT) was performed on 138 patients suffering from severe head injuries (8 or less on the Glasgow Coma Scale). Standard practice called for scans to be done upon admission (within hours of the injury), and after 1, 3, 7 days and 1 month. Subsequent CT's depended on the patient's condition. Clinical results at the time of discharge were graded according to the Glasgow Outcome Scale. Patients who died, were in a persistent vegetative state, or were severely disabled were considered to have a ''bad outcome''. On the other hand, patients who were somewhat disabled or made good recoveries were considered to have a ''good outcome''. During the serial CT scan, there were new findings (not visualized on the initial CT but appearing on subsequent ones) in 91 of the 138 patients. These new findings were classified as follows; 1) decreased density collection in the subdural space (DDC), 2) ventricular dilation (VD), 3) intracerebral hematoma (ICH), 4) intraventricular hemorrhage (IVH), 5) extracerebral hematoma (ECH), 6) edema (E), 7) infarction (I). We defined ICH, IVH, ECH, E and I as new lesions. Of the 60 patients with new lesions 12 had good outcomes and 48 had poor outcomes. There were 78 patients who did not have any new lesions, 60 with good outcomes and 18 with poor outcomes. A significant correlation was found between good outcomes and the absence of new lesions, and between bad outcomes and the development of new lesions (p 2 = 44.038). We conclude that SCT can help predict the outcome with severe head injury patients and may be very important in their examination and care. (J.P.N.)

    Full Text Available Abstract Background Preterm birth (PTB is a major cause of infant morbidity and mortality, but the relationship between comorbidity and PTB by clinical subtype and severity of gestational age remains poorly understood. We evaluated associations between maternal comorbidities and PTB by clinical subtype and gestational age. Methods We conducted a retrospective cohort study of 1,329,737 singleton births delivered in hospitals in the province of Québec, Canada, 1989-2006. PTB was classified by clinical subtype (medically indicated, preterm premature rupture of membranes (PPROM, spontaneous preterm labour and gestational age ( Results PTB rates were higher among mothers with comorbidity (10.9% compared to those without comorbidity (4.7%. Several comorbidities were associated with greater odds of medically indicated PTB compared with no comorbidity, but only comorbidities localized to the reproductive system were associated with spontaneous PTB. Drug dependence and mental disorders were strongly associated with PPROM and spontaneous PTBs across all gestational ages (OR > 2.0. At the population level, several major comorbidities (placental abruption, chorioamnionitis, oliogohydramnios, structural abnormality, cervical incompetence were key contributors to all clinical subtypes of PTB, especially at Conclusions The relationship between comorbidity and clinical subtypes of PTB depends on gestational age. Prevention of PPROM and spontaneous PTB may benefit from greater attention to preeclampsia, anemia and comorbidities localized to the reproductive system.

    Severe thalassemia diseases are a major health problem in Southeast Asia. In Cambodia, there has never been a significant program for prevention or control of severe thalassemia. We, therefore, studied the effect of a health education program on severe thalassemia prevention and control in Phnom Penh, Cambodia. A quasi-experimental study in several communities around Phnom Penh was done. The respective intervention and control group comprised 124 and 117 people, between 18 and 40 years of age, male and female. Pre- and post-tests using a validated and reliable questionnaire were performed in the intervention group and one test was done in the control group. A health education program was organized to give important information to the intervention group and, at the end of the process, to the control group. The outcomes were evaluations of their knowledge and attitude vis-à-vis severe thalassemia prevention and control, and participating in thalassemia screening. Among participants in the intervention group, 105 (84.7%) considered undergoing blood screening vs. 65 (55.6%) in the control group ( p -value < 0.001). In the intervention group, the respective mean scores for knowledge and attitude to a prevention and control program for severe thalassemia before and after health education were 2.6 VS 6.5 ( p -value < 0.001) and 4.6 VS 6.5 ( p -value < 0.001). The intention to undergo screening was significantly higher in the intervention group than the control group. Knowledge and attitude towards prevention and control of severe thalassemia was significantly improved in the intervention group. Health education clearly heightens awareness and improves consideration of screening for prevention and control of severe thalassemia.

    Full Text Available Background: Severe, drug-resistant gastroparesis is a debilitating condition. Several, but not all, patients can get significant relief from nausea and vomiting by gastric electrical stimulation (GES. A trial of temporary, endoscopically delivered GES may be of predictive value to select patients for laparoscopic-implantation of a permanent GES device. Materials and Methods: We conducted a clinical audit of consecutive gastroparesis patients, who had been selected for GES, from May 2008 to January 2012. Delayed gastric emptying was diagnosed by scintigraphy of ≥50% global improvement in symptom-severity and well-being was a good response. Results: There were 71 patients (51 women, 72% with a median age of 42 years (range: 14-69. The aetiology of gastroparesis was idiopathic (43 patients, 61%, diabetes (15, 21%, or post-surgical (anti-reflux surgery, 6 patients; Roux-en-Y gastric bypass, 3; subtotal gastrectomy, 1; cardiomyotomy, 1; other gastric surgery, 2 (18%. At presentation, oral nutrition was supplemented by naso-jejunal tube feeding in 7 patients, surgical jejunostomy in 8, or parenterally in 1 (total 16 patients; 22%. Previous intervention included endoscopic injection of botulinum toxin (botox into the pylorus in 16 patients (22%, pyloroplasty in 2, distal gastrectomy in 1, and gastrojejunostomy in 1. It was decided to directly proceed with permanent GES in 4 patients. Of the remaining, 51 patients have currently completed a trial of temporary stimulation and 39 (77% had a good response and were selected for permanent GES, which has been completed in 35 patients. Outcome data are currently available for 31 patients (idiopathic, 21 patients; diabetes, 3; post-surgical, 7 with a median follow-up period of 10 months (1-28; 22 patients (71% had a good response to permanent GES, these included 14 (68% with idiopathic, 5 (71% with post-surgical, and remaining 3 with diabetic gastroparesis.

MetS has traditionally been classified based on dichotomous criteria that deny that MetS-related risk likely exists as a spectrum. Continuous MetS scores provide a way to track MetS-related risk over time. We generated MetS severity scores that are sex- and race/ethnicity-specific, acknowledging that the way MetS is manifested may be different by sex and racial/ethnic subgroup. These scores are correlated with long-term risk for type 2 diabetes mellitus and cardiovascular disease. Clinical use of scores like these provide a potential opportunity to identify patients at highest risk, motivate patients toward lifestyle change, and follow treatment progress over time.

    Acute severe colitis is a potentially lethal medical emergency and, even today, its treatment remains a challenge for clinicians and surgeons. Intravenous corticoid therapy, which was introduced into the therapeutic arsenal in the 1950s, continues to be the first-line treatment and, for patients who are refractory to this, the rescue therapy may consist of clinical measures or emergency colectomy. To evaluate the indications for and results from drug rescue therapy (cyclosporine, infliximab and tacrolimus), and to suggest a practical guide for clinical approaches. The literature was reviewed using the Medline/PubMed, Cochrane library and SciELO databases, and additional information from institutional websites of interest, by cross-correlating the following keywords: acute severe colitis, fulminating colitis and treatment. Treatments for acute severe colitis have avoided colectomy in 60-70% of the cases, provided that they have been started early on, with multidisciplinary follow-up. Despite the adverse effects of intravenous cyclosporine, this drug has been indicated in cases of greater severity with an imminent risk of colectomy, because of its fast action, short half-life and absence of increased risk of surgical complications. Therapy using infliximab has been reserved for less severe cases and those in which immunosuppressants are being or have been used (AZA/6-MP). Indication of biological agents has recently been favored because of their ease of therapeutic use, their good short and medium-term results, the possibility of maintenance therapy and also their action as a "bridge" for immunosuppressant action (AZA/6-MP). Colectomy has been reserved for cases in which there is still no response five to seven days after rescue therapy and in cases of complications (toxic megacolon, profuse hemorrhage and perforation). Patients with a good response to rescue therapy who do not undergo emergency operations should be considered for maintenance therapy using

    The System 80 + design is ABB-CE's standardized evolutionary Advanced Light Water Reactor (ALWR) design. It incorporates design enhancements based on Probabilistic Risk Assessment (PRA) insights, guidance from the ALWR Utility Requirements Document (URD), and US NRC's Severe Accident Policy. Major severe accident prevention and mitigation design features of the System 80 + design are described. The results of the System 80 + PRA are presented and the insights gained from the PRA sensitivity analyses are discussed. ABB-CE considered defense-in-depth for accident prevention and mitigation early in the design process and used robust design features to ensure that the System 80 + design achieved a low core damage frequency, low containment conditional failure probability, and excellent deterministic containment performance under severe accident conditions and to ensure that the risk was properly allocated among design features and between prevention and mitigation.

    2012-01-01

    Full Text Available Respiratory syncytial virus plays a significant role in etiology of respiratory infections in infants, and preterm children have muchhigher risk of severe course of the disease, than common population of children at the age less than 2 years old. Palivizumab is usedefficiently to prevent this infection. The aim of this study was to assess the efficacy of the costs on palivizumab in preterm childrenin the Russian Federation. The assessment was based on meta-analysis of randomized clinical trials. According to the World Health organization recommendations, the acceptable value of the variable «costs/efficacy» must not be higher than threefold of the gross domestic product per person. On the assumption of this fact, the coefficient «costs/efficacy» for the Russian Federation according to the 2011 year results must not be higher than 1140 thousand rubles per 1 extra year of life. Analysis from the position of health care system shows, that coefficient «costs/efficacy» with palivazumab usage in children with gestation age from 28 to 32 weeks rangesfrom 594,4 to 1030,4 thousand roubles per 1 extra year of life when starting the prophylaxis during first 6 month of life. Under the social perspective of the study (accounting for direct and indirect costs the coefficient «costs/efficacy» decreases to 515,8–951,8 thousands roubles per 1 extra year of life. Thereby, nowadays the prophylaxis of severe respiratory cyncytial infection with palivazumab is acceptable according to the economical point of view in preterm children with the gestation age 32 weeks and less when starting during first 6 months of life.

    Full Text Available Background: It is widely recognized that asthma control is not always possible in patients with very severe asthma despite available treatment. The aim of this study was to evaluate the efficacy of Omalizumab on asthma control as an add‐on therapy in patients from the “Severe Asthma Outpatient Service” of Pulido Valente Hospital in Lisbon, Portugal. Methods: A retrospective study was conducted to assess asthma control by the ACT score and by GINA classification, frequency and severity of exacerbations, medication use and pulmonary function in patients treated with Omalizumab. Clinical information was collected from medical records from the start of treatment and at 6‐, 12‐ and 24‐month follow‐ups. Results: 26 patients started the treatment with Omalizumab, and all (100% were classified by GINA with uncontrolled asthma prior to treatment. Mean ACT score was 11.5. All the patients had treatment with fixed‐dose ICS and LABA and 34.6% also had an anti‐cholinergic inhaler. 42.3% of patients were also treated with oral glucocorticosteroids for control. Patients reported an average of 1.8 moderate and 3.1 severe exacerbations/year. Statistical differences were found at 6‐month follow‐up in most end‐points: GINA score improved: 60.9% of patients with partially controlled asthma and only 39.1% with uncontrolled asthma (Wilcoxon 0.00; ACT score improved to 19.52 (Wilcoxon 0.00; mean FEV1 improved to 76.7% (Wilcoxon 0.025; the proportion of patients requiring oral glucocorticosteroid therapy reduced to 17.4% (Wilcoxon 0.014; and the number of moderate and severe exacerbations also decreased to 1.04 and 1.83 respectively (Wilcoxon 0.007; Wilcoxon 0.002 respectively.

    The caries prevention by using laser irradiation has been investigated during the last 30 years. The Nd: YAG laser associated with acidulated phosphate fluoride has been shown as a very promising technique for enamel caries prevention. The aim of this work was to clinically evaluate the efficiency of Nd: YAG laser associated with acidulated phosphate fluoride in pit and fissure caries prevention of children and adolescents. In this work it was determined the dye that enhance the effect of Nd: YAG laser in enamel. It was selected 242 pre-molar and molar teeth from 33 children and adolescents, aged from 7 to 15 years old. The selected teeth were free from caries or decalcification marks (active white marks) to the clinical and radiographic exams. The teeth were divided into two groups: the first group was laser irradiated and their homologous remained as a control. The right side teeth were dye-assisted Nd:YAG laser irradiated. The dye solution was a moisture of dust coal and equal parts of water and alcohol. The irradiation conditions were 60 mJ/10 Hz, optical fiber in contact mode, with diameter of 300 μm, resulting in an energy density of 84,9 J/cm 2 . The oclusal surface of the teeth was completely irradiated, specially on the slopes and in the deepest part of the pits and fissures. This procedure was repeated three times. In the sequence it was applied the acidulated phosphate fluoride for 4 minutes. On the left side teeth - control group- only acidulated phosphate fluoride was applied for the same time. The final examination considered the presence of caries and active white marks after a period of one year. There were statistical significant differences (p < 0.01) between the lased + fluoride group and the non irradiated group. The present study concluded that the technique used in this work can be an alternative clinical method for caries prevention. (author)

    2017-02-01

    The aim of this study was to create and validate severity levels for the central sensitization inventory (CSI), a valid and reliable patient-reported outcome instrument designed to identify patients whose presenting symptoms may be related to a central sensitivity syndrome (CSS; eg, fibromyalgia, chronic fatigue syndrome, irritable bowel syndrome), with a proposed common etiology of central sensitization (CS). Based on CSI score means and standard deviations from previously published subject samples, the following CSI severity levels were established: subclinical = 0 to 29; mild = 30 to 39; moderate = 40 to 49; severe = 50 to 59; and extreme = 60 to 100. The concurrent validity of the CSI severity levels was then confirmed in a separate chronic pain patient sample (58% with a CSS diagnosis and 42% without) by demonstrating associations between CSI scores and (1) the number of physician-diagnosed CSSs; (2) CSI score distributions in both CSS and non-CSS patient samples; (3) patient-reported history of CSSs; and (4) patient-reported psychosocial measures, which are known to be associated with CSSs. Compared to the non-CSS patient subsample, the score distribution of the CSS patient subsample was skewed toward the higher severity ranges. CSI mean scores moved into higher severity levels as the number of individual CSS diagnoses increased. Patients who scored in the extreme CSI severity level were more likely to report previous diagnoses of fibromyalgia, chronic fatigue syndrome, temporomandibular joint disorder, tension/migraine headaches, and anxiety or panic attacks (P < 0.01). CSI severity levels were also associated with patient-reported depressive symptoms, perceived disability, sleep disturbance, and pain intensity (P ≤ 0.02). This study provides support for these CSI severity levels as a guideline for healthcare providers and researchers in interpreting CSI scores and evaluating treatment responsiveness. © 2016 World Institute of Pain.

    Craniofacial dysostosis (Crouzon's syndrome) is a well defined, dominantly inherited disorder, described by Crouzon in 1912. It is characterized by several deformities involving the skull,face and eyes. This case report details a rare form of Crouzon's syndrome in which proptosis was so severe that globes were completely proptotic outside the patient's extremely shallow orbits, and the eyelids were undeveloped bilaterally and replaced by small folds of skin. It appears that this is the first report of such a severe form of Crouzon's syndrome. (author)

    2013-01-01

    Based on this characteristic of fast reactor core, potential impact of CDA (Core Disruptive Accident) caused by ATWS has been considered as an important safety issue, although it is extremely unlikely. In order to prevent and mitigate the severe accident, the fast reactor core has been designed with various safety features. In this paper, as a part of study to develop the domestic regulatory requirements and guidelines related to SFR core safety, international trends on safety features which have been considered in current SFR cores are reviewed. In order to develop the regulatory requirements and guidelines related to a SFR core design for prevention of CDA, the core safety features were reviewed. The safety features considered in current SFR cores have a function that prevents to progress into next step in accident sequences. The trends on current safety features are as follows: · 'passive shutdown systems' to prevent initiating events such as ULOF, UTOP, ULOHS, etc · 'core designs with low void effect' to prevent the large void reactivity insertion in initiating phase · 'specific provisions for core with conventional positive void effect' to prevent the core recriticality in transition phase Consequently, in regulatory review requirements and guidelines developed for SFR, contents for not only reduction of positive void effect but also features to ensure the safety of overall system should be reflected

    Bondü, Rebecca; Scheithauer, Herbert

    2009-01-01

    In March and September 2009 the school shootings in Winnenden and Ansbach once again demonstrated the need for preventive approaches in order to prevent further offences in Germany. Due to the low frequency of such offences and the low specificity of relevant risk factors known so far, prediction and prevention seems difficult though. None the less, several preventive approaches are currently discussed. The present article highlights these approaches and their specific advantages and disadvantages. As school shootings are multicausally determined, approaches focussing only on single aspects (i.e. prohibiting violent computer games or further strengthening gun laws) do not meet requirements. Other measures such as installing technical safety devices or optimizing actions of police and school attendants are supposed to reduce harm in case of emergency. Instead, scientifically founded and promising preventive approaches focus on secondary prevention and for this purpose employ the threat assessment approach, which is widespread within the USA. In this framework, responsible occupational groups such as teachers, school psychologists and police officers are to be trained in identifying students' warning signs, judging danger of these students for self and others in a systematic process and initiating suitable interventions.

    Mature green banana (GB) fruit is rich in amylase-resistant starch that stimulates colonic production of short-chain fatty acids (referred to as fatty acid) and is useful in treating diarrheal diseases. We studied therapeutic effects of GB in childhood shigellosis by determining colonic fatty acid production in a double-blind, randomized, controlled, clinical trial. Seventy-three children aged 6 to 60 months with severe bloody dysentery caused by Shigella infection were either given a rice-based diet (54 kcal/dL), with cooked GB (250 g/L) (n = 34) or without GB (n = 39) for 5 days; all given ciprofloxacin (15 mg/kg, q12 hours). Stool volume, frequency, excretion of blood/mucus, and relevant clinical and laboratory indices were determined. On day 5 (post-treatment), 59% children in GB group had no mucus compared with 36% in controls, fecal blood was completely cleared from 96% in GB group compared with 60% without GB (P < 0.05). GB treatment significantly reduced (P < 0.01) numbers of stools/day compared with controls (70% vs. 50%, P < 0.05). GB-specific reductions of mean fecal volumes (mL/kg) ranged from 25% to 40%; (P < 0.05) during the 5-day observations. Clinical success rates were 85% in GB group compared with 67% in controls (P < 0.05). GB significantly (P < 0.01) reduced fecal myeloperoxidase activity and increased fecal fatty acid concentrations (P < 0.01). GB diet improves clinical severity in childhood shigellosis and could be a simple and useful adjunct for dietary management of this illness.

    The emergence of advanced genetic technologies raises many challenges for dementia care and the conduct of related social, behavioural and clinical research. Genetic tests are already used to identify possible participants in dementia prevention trials. These tests are unlike any other in clinical medicine as they have the capacity to predict disease onset after intervals of many years with implications for other family members. Genetic counselling professionals support services in paediatrics, cancer diagnosis and some adult-onset diseases. Their capacity cannot meet the needs for pre- and post-test support of the many "at-risk" families living with late onset dementia. Most dementias are common, complex conditions in which multiple genetic and environmental factors play important and potentially modifiable roles. Large scale prevention studies are needed to test the effectiveness of interventions. Some economy of effort will be achieved by the preferential inclusion of "at-risk" families. Many such families are in contact with dementia care services and will be motivated to participate in prevention studies. However, practice standards and consensus-based guidelines do not yet exist. Support services are not available on a scale sufficient to prevent harm when risk is poorly communicated causing unnecessary psychological morbidity in unaffected family members. There is a pressing need for research to inform the development of study guidelines and to identify how services are strengthened to support these families during and after their participation in trials. Discourse analysis provides a useful method to collect and analyse data of this type and supports the conclusions of this review. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

  20. Severe Rebound-Associated Vertebral Fractures After Denosumab Discontinuation: 9 Clinical Cases Report.

    Denosumab inhibits bone resorption, increases bone mineral density, and reduces fracture risk. Denosumab was approved for the treatment of osteoporosis and the prevention of bone loss in some oncological situations. Denosumab discontinuation is associated with a severe bone turnover rebound (BTR) and a rapid loss of bone mineral density. The clinical consequences of the BTR observed after denosumab discontinuation are not known. We report 9 women who presented 50 rebound-associated vertebral fractures (RAVFs) after denosumab discontinuation. A broad biological and radiological assessment excluded other causes than osteoporosis. These 9 cases are unusual and disturbing for several reasons. First, all vertebral fractures (VFs) were spontaneous, and most patients had a high number of VFs (mean = 5.5) in a short period of time. Second, the fracture risk was low for most of these women. Third, their VFs occurred rapidly after last denosumab injection (9-16 months). Fourth, vertebroplasty was associated with a high number of new VFs. All the observed VFs seem to be related to denosumab discontinuation and unlikely to the underlying osteoporosis or osteopenia. We hypothesize that the severe BTR is involved in microdamage accumulation in trabecular bone and thus promotes VFs. Studies are urgently needed to determine 1) the pathophysiological processes involved, 2) the clinical profile of patients at risk for RAVFs, and 3) the management and/or treatment regimens after denosumab discontinuation. Health authorities, physicians, and patients must be aware of this RAVF risk. Denosumab injections must be scrupulously done every 6 months but not indefinitely.

    We wished to validate our recently devised 16-item ENLIST ENL Severity Scale, a clinical tool for measuring the severity of the serious leprosy associated complication of erythema nodosum leprosum (ENL). We also wished to assess the responsiveness of the ENLIST ENL Severity Scale in detecting clinical change in patients with ENL. Participants, recruited from seven centres in six leprosy endemic countries, were assessed using the ENLIST ENL Severity Scale by two researchers, one of whom categorised the severity of ENL. At a subsequent visit a further assessment using the scale was made and both participant and physician rated the change in ENL using the subjective categories of "Much better", "somewhat better", "somewhat worse" and "much worse" compared with "No change" or "about the same". 447 participants were assessed with the ENLIST ENL Severity Scale. The Cronbach alpha of the scale and each item was calculated to determine the internal consistency of the scale. The ENLIST ENL Severity Scale had good internal consistency and this improved following removal of six items to give a Cronbach's alpha of 0.77. The cut off between mild ENL and more severe disease was 9 determined using ROC curves. The minimal important difference of the scale was determined to be 5 using both participant and physician ratings of change. The 10-item ENLIST ENL Severity Scale is the first valid, reliable and responsive measure of ENL severity and improves our ability to assess and compare patients and their treatments in this severe and difficult to manage complication of leprosy. The ENLIST ENL Severity Scale will assist physicians in the monitoring and treatment of patients with ENL. The ENLIST ENL Severity Scale is easy to apply and will be useful as an outcome measure in treatment studies and enable the standardisation of other clinical and laboratory ENL research.

    To study the long-term use of self-study material in type 1 diabetes patient education targeted at the prevention of severe hypoglycaemia. Randomized 1:1:1 control study in three local hospitals. We studied 332 type 1 diabetes patients from the geographic population, aged 2.6-18.9 y at entry. The intervention group received a videotape and brochure in which interviewed patients, parents and medical experts reviewed in detail practical skills for self-control and treatment, with the aim of preventing severe hypoglycaemia. There were two control groups: one received a videotape and brochure with general diabetes information and the other only traditional treatment. Primary endpoints were severe hypoglycaemia needing assistance by another person and HbA1c. Dissemination, reading/viewing level, patients' attitudes and extra contact with caregivers were also investigated. At 24 mo, 249 subjects provided data. The yearly incidence of severe hypoglycaemia decreased at 24 mo from 42% to 25% (difference 17%, 95% CI 3-31, p = 0.0241) in the intervention group, but not in controls. HbA1c remained unchanged. Video use during months 13-24 was higher in the intervention group than in controls (p = 0.0477), ranging from 1-15 (median 2) times, among 37% of patients (months 1-12, 100%). Higher future use was anticipated for intervention material (p = 0.0003). Extra caregiver contact was related to severe hypoglycaemia (p = 0.0009). The cost of the material was quality video programmes and brochures may reach high dissemination levels and, when targeted, contribute to the prevention of severe hypoglycaemia over a longer period of time, being a cost-effective complement to traditional care.

    Objective: To study the correlation between the manifestations of the posterior pararenal space (PPS) involvement and the clinical severity, CT severity index (CTSI) of acute pancreatitis (AP), and to ascertain the value of PPS involvement in assessing the severity of AP. Methods: The CT images of 87 cases in AP were retrospectively observed. Clinical severity, CTSI, and CT grading of the PPS involvement of AP were assessed and scored, respectively. Results: CT morphologic and craniocaudal extent grading of the PPS abnormalities had positive correlation with clinical severity grading and CTSI of AP (P<0.05). CT morphologic grading of the PPS also had positive correlation with its craniocaudal extent CT grading (P<0.05). For predicting the severity of AP, the abnormalities of the PPS had sensitivity of 60.3%, specificity of 87.5%, positive predictive value of 92.7%, negative predictive value of 45.7%, and accuracy of 67.8%. Conclusion: PPS involvement and it's severity in AP could reflect the severity of AP to some extent, and may be helpful for initial excluding mild AP. (authors)

    Improving access to preventive care requires addressing patient, provider, and systems barriers. Patients often lack knowledge or are skeptical about the importance of prevention. Physicians feel that they have too little time, are not trained to deliver preventive services, and are concerned about the effectiveness of prevention. We have implemented an educational module in the required family practice clerkship (1) to enhance medical student learning about common clinical preventive services and (2) to teach students how to inform and involve patients in shared decision making about those services. Students are asked to examine available evidence-based information for preventive screening services. They are encouraged to look at the recommendations of various organizations and use such resources as reports from the U.S. Preventive Services Task Force to determine recommendations they want to be knowledgeable about in talking with their patients. For learning shared decision making, students are trained to use a model adapted from Braddock and colleagues(1) to discuss specific screening services and to engage patients in the process of making informed decisions about what is best for their own health. The shared decision making is presented and modeled by faculty, discussed in small groups, and students practice using Web-based cases and simulations. The students are evaluated using formative and summative performance-based assessments as they interact with simulated patients about (1) screening for high blood cholesterol and other lipid abnormalities, (2) screening for colorectal cancer, (3) screening for prostate cancer, and (4) screening for breast cancer. The final student evaluation is a ten-minute, videotaped discussion with a simulated patient about screening for colorectal cancer that is graded against a checklist that focuses primarily on the elements of shared decision making. Our medical students appear quite willing to accept shared decision making as

    Calcimimetic NPS R-568 prevents parathyroid hyperplasia in rats with severe secondary hyperparathyroidism. Secondary hyperparathyroidism (secondary HPT) in chronic renal insufficiency (CRI) is characterized by multiglandular hyperplasia. In this study, we investigated the effects of the calcimimetic NPS R-568 on the parathyroid gland in rats with CRI induced by ligation of the renal arteries and severe secondary HPT induced by dietary phosphorus loading. Six days after surgery, high-phosphorus diet feeding was started, and NPS R-568 was administered to the rats for 56 days either by daily gavage (30 or 100 micromol/kg) or by continuous subcutaneous infusion (20 micromol/kg. day). After 54 days, serum PTH levels in vehicle-treated CRI rats were 1019 vs. 104 pg/mL in sham-operated controls. Infusion of NPS R-568 maintained serum PTH at levels comparable with those of sham-operated controls, whereas daily gavage also prevented much of the increase in CRI controls and decreased PTH levels intermittently in a dose-dependent fashion. Parathyroid gland enlargement was caused predominantly by hyperplasia. Total cell number per kg body wt was 3.5-fold higher in vehicle-treated CRI rats than in sham-operated controls. Both infusion and high-dose gavage of NPS R-568 completely prevented the increase in parathyroid cell number. These results demonstrate that the calcimimetic compound NPS R-568 can prevent both the increase in serum PTH levels and parathyroid hyperplasia in rats with CRI and severe secondary HPT. Moreover, these changes occurred despite decreases in serum 1, 25(OH)2D3 and increases in serum phosphate, suggesting a dominant role for the calcium receptor in regulating parathyroid cell proliferation.

    Full Text Available Tooth wear is attributed to several factors many of which often remain unidentified. Management of tooth wear is challenging in preventive and restorative dentistry. Correct assessment of occlusal vertical dimension, interocclusal rest space, and centric relation records are critical for successful treatment. In order to evaluate different treatment modalities and select the treatment of choice some information can be obtained from study casts and diagnostic wax-up. In order to achieve a predictable and desirable result, a systematic approach may be helpful. This paper describes the full mouth rehabilitation of a 36-year-old bruxer with severely worn dentition and other dental problems such as unfavorable restorations. A diagnostic work-up was performed and provisional restorations were made; then, they were clinically evaluated and adjusted based on the criteria dictating esthetics, phonetics, and vertical dimension. After endodontic therapy, clinical crown lengthening was performed. Two short implants were inserted in the posterior mandible. Custom-cast dowel cores and metal-ceramic restorations were fabricated and a full occlusal splint was used to protect the restorations. We ensured stable contacts on all teeth with equal intensity in centric relation and anterior guidance in accord with functional jaw movements.

    Full Text Available OBJECTIVES: The aim of this study was to explore cognitive flexibility in a large dataset of people with Eating Disorders and Healthy Controls (HC and to see how patient characteristics (body mass index [BMI] and length of illness are related to this thinking style. METHODS: A dataset was constructed from our previous studies using a conceptual shift test--the Brixton Spatial Anticipation Test. 601 participants were included, 215 patients with Anorexia Nervosa (AN (96 inpatients; 119 outpatients, 69 patients with Bulimia Nervosa (BN, 29 Eating Disorder Not Otherwise Specified (EDNOS, 72 in long-term recovery from AN (Rec AN and a comparison group of 216 HC. RESULTS: The AN and EDNOS groups had significantly more errors than the other groups on the Brixton Test. In comparison to the HC group, the effect size decrement was large for AN patients receiving inpatient treatment and moderate for AN outpatients. CONCLUSIONS: These findings confirm that patients with AN have poor cognitive flexibility. Severity of illness measured by length of illness does not fully explain the lack of flexibility and supports the trait nature of inflexibility in people with AN.

    2010-01-01

    The EPR TM has incorporated several design features in order to specifically address major severe accident safety issues. In particular, it was designed with the objective to transfer high pressure core melt scenarios into a low pressure scenario with high reliability so that a high pressure vessel failure can be practically eliminated. It is the key issue in the defense-in-depth approach, for a postulated severe accident with core melting, to prevent any risk of containment failure due to possible Direct Containment Heating or due to reactor vessel rocketing which results from vessel failure at high pressure. Temperature-induced steam generator tube rupture, which could lead to a radiological containment bypass, has also to be prevented. On the basis of the analysis of the main high pressure core melt scenarios which are calculated with the MAAP4.07 code which was developed to support the EPR TM, this paper explores the benefits of primary depressurization by dedicated valves on transient evolutions. It specifically addresses the thermal response of the structures by sensitivity studies involving the timing of valve actuation. It outlines that a grace period of at least one hour is available for a delayed valve actuation without inducing excessive loads and without increasing the risk of a temperature-induced steam generator tube rupture.

    Summary Background The Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI) was developed for use in clinical trials and longitudinal patient assessment. Objectives To characterize disease severity using the CDASI and assess responsiveness of this instrument to clinically meaningful changes in disease activity. Methods Patients with cutaneous dermatomyositis at the University of Pennsylvania (UPenn, n = 93) and Stanford University (Stanford, n = 106) were prospectively evaluated using the CDASI, physician global assessment (PGA) Likert scales, and visual analog scale (VAS). Data was analyzed using logistic regression models and receiver operating characteristic curves to select cut-offs. Results Baseline CDASI activity scores for the patients evaluated at UPenn ranged from 0 to 47 (median 17), and baseline PGA VAS scores ranged from 0 to 9.6 (median 1.1). At UPenn a CDASI activity score of 19 differentiated mild from moderate and severe disease. At Stanford baseline CDASI scores ranged from 0 to 48 (median 21), baseline PGA VAS scores ranged from 0 to 9.7 (median 4.2) and CDASI activity scores of 14 or less characterized mild disease. When a 2 cm change in the PGA VAS was regarded as a clinically significant improvement, a 4-point (UPenn) or 5-point (Stanford) change in CDASI reflected a minimal clinically significant response. Conclusions The CDASI is a valid and responsive measure that can be used to characterize cutaneous dermatomyositis severity and detect improvement in disease activity. Variations in cutoffs may be due to differences in disease severity between the two populations or inter-rater variations in use of the external gold measures. PMID:25994337

    Plant features and operator actions which have been found to be important in either preventing or mitigating severe accidents in PWRs with large dry containments have been identified. These features and actions were developed from insights derived from reviews of risk assessments performed specifically for the Zion plant and from assessments of other relevant studies. Accident sequences that dominate the core-damage frequency and those accident sequences that are of potentially high consequence were identified. Vulnerabilities of the large dry containment to severe accident containment loads were also identified. In addition, those features of a PWR with a large dry containment, which are important for preventing core damage and are available for mitigating fission-product release to the environment were identified. The report is issued to provide focus to the analyst examining an individual plant. The report calls attention to plant features and operator actions and provides a list of deterministic tributes for assessing those features and actions found to be helpful in reducing the overall risk for Zion and other PWRs with large dry containments. Thus, the guidance is offered as a resource in examining the subject plant to determine if the same, or similar, plant features and operator actions will be of value in reducing overall plant risk.

    Plant features and operator actions, which have been found to be important in either preventing or mitigating severe accidents in BWRs with Mark II containments (BWR Mark II's) have been identified. These features and actions were developed from insights derived from reviews of in-depth risk assessments performed specifically for the Limerick and Shoreham plants and from other relevant studies. Accident sequences that dominate the core-damage frequency and those accident sequences that are of potentially high consequence were identified. Vulnerabilities of the BWR Mark II to severe-accident containment loads were also noted. In addition, those features of a BWR Mark II, which are important for preventing core damage and are available for mitigating fission-product release to the environment were also identified.

    Full Text Available The preventative and curative effects of some plant derived agents based on plant extracts or essential oils were studied at different concentrations against Erysiphe cichoracearum DC. ex Merat, the causal pathogen of okra powdery mildew by the detached leaf-disk and potted plants bioassays. Through detached leaf-disk assay, the highest mean preventative effect (97.74% was recorded by neem seed oil followed by jojoba oil (89.82% and extract of Rynoutria sachalinensis (82.77%. Neem seed oil at 1% was the most effective agent followed by jojoba oil and extract of R. sachalinensis at 1.5% and 2%, respectively, where they suppressed E. cichoracearum completely. Potted plants assay revealed that neem seed oil, jojoba oil and extract of R. sachalinensis as well as the fungicide (active ingredient dinocap showed higher preventative efficacy at all leaf olds treated after 7 and 14 days of inoculation as compared with extracts of henna and garlic. Moreover, the preventative efficacy partly remained apparent after 14 days of inoculation at all leaf olds tested. In field trials through 2010 and 2011 growing seasons, when the first symptoms of powdery mildew appeared naturally, 1.5% jojoba oil, 2% extract of R. sachalinensis and 1% neem seed oil were sprayed individually twice on grown plants to evaluate their efficacy on controlling powdery mildew, growth and yield of okra. Resulted showed that neem seed oil was the most effective agent and highly decreased the disease severity to 29.92%, recorded the highly curative effect (68.15% and also improved plant growth and pods yield.

    Full Text Available As part of federal and local efforts to increase access to high quality, clinical preventive services (CPS in underserved populations, the Los Angeles County Department of Public Health (DPH partnered with six local health system and community organization partners to promote the use of team care for CPS delivery. Although these partners were at different stages of organizational capacity, post-program review suggests that each organization advanced team care in their clinical or community environments, potentially affecting >250,000 client visits per year. Despite existing infrastructure and DPH’s funding support of CPS integration, partner efforts faced several challenges. They included lack of sustainable funding for prevention services; limited access to community resources that support disease prevention; and difficulties in changing health-care provider behavior. Although team care can serve as a catalyst or vehicle for delivering CPS, downstream sustainability of this model of practice requires further state and national policy changes that prioritize prevention. Public health is well positioned to facilitate these policy discussions and to assist health system and community organizations in strengthening CPS integration.

    Full Text Available Abstract Background Several countries have established or are planning acute psychiatric in-patient services that accept around-the-clock emergency admission of adolescents. Our aim was to investigate the characteristics and clinical outcomes of a cohort of patients at four Norwegian units. Methods We used a prospective pre-post observational design. Four units implemented a clinician-rated outcome measure, the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA, which measures mental health problems and their severity. We collected also data about the diagnoses, suicidal problems, family situations, and the involvement of the Child Protection Service. Predictions of outcome (change in HoNOSCA total score were analysed with a regression model. Results The sample comprised 192 adolescents admitted during one year (response rate 87%. Mean age was 15.7 years (range 10-18 and 70% were girls. Fifty-eight per cent had suicidal problems at intake and the mean intake HoNOSCA total score was 18.5 (SD 6.4. The largest groups of main diagnostic conditions were affective (28% and externalizing (26% disorders. Diagnoses and other patient characteristics at intake did not differ between units. Clinical psychiatric disorders and developmental disorders were associated with severity (on HoNOSCA at intake but not with outcome. Of adolescents ≥ 16 years, 33% were compulsorily admitted. Median length of stay was 8.5 days and 75% of patients stayed less than a month. Compulsory admissions and length of stay varied between units. Mean change (improvement in the HoNOSCA total score was 5.1 (SD 6.2, with considerable variation between units. Mean discharge score was close to the often-reported outpatient level, and self-injury and emotional symptoms were the most reduced symptoms during the stay. In a regression model, unit, high HoNOSCA total score at intake, or involvement of the Child Protection Service predicted improvement during admission

    To study muscle biopsy tissue from patients with juvenile dermatomyositis (JDM) in order to test the reliability of a score tool designed to quantify the severity of histological abnormalities when applied to biceps humeri in addition to quadriceps femoris. Additionally, to evaluate whether elements of the tool correlate with clinical measures of disease severity. 55 patients with JDM with muscle biopsy tissue and clinical data available were included. Biopsy samples (33 quadriceps, 22 biceps) were prepared and stained using standardised protocols. A Latin square design was used by the International Juvenile Dermatomyositis Biopsy Consensus Group to score cases using our previously published score tool. Reliability was assessed by intraclass correlation coefficient (ICC) and scorer agreement (α) by assessing variation in scorers' ratings. Scores from the most reliable tool items correlated with clinical measures of disease activity at the time of biopsy. Inter- and intraobserver agreement was good or high for many tool items, including overall assessment of severity using a Visual Analogue Scale. The tool functioned equally well on biceps and quadriceps samples. A modified tool using the most reliable score items showed good correlation with measures of disease activity. The JDM biopsy score tool has high inter- and intraobserver agreement and can be used on both biceps and quadriceps muscle tissue. Importantly, the modified tool correlates well with clinical measures of disease activity. We propose that standardised assessment of muscle biopsy tissue should be considered in diagnostic investigation and clinical trials in JDM. Published by the BMJ Publishing Group Limited.

    Several studies have reported the benefits of motorcycle antilock braking systems (ABS) in reducing injury crashes, due to improved stability and braking performance. Both aspects may prevent crashes but may also reduce the crash severity when a collision occurs. However, it is still unknown to what extent the reductions in injury crashes with ABS may be due to a combination of these mechanisms. Swedish hospital and police reports (2003-2012) were used. The risk for permanent medical impairment (RPMI) was calculated, showing the risk of at least 1 or 10% permanent medical impairment. In total, 165 crashes involving ABS-equipped motorcycles were compared with 500 crashes with similar motorcycles without ABS. The analysis was performed in 3 steps. First, the reduction in emergency care visits with ABS was calculated using an induced exposure approach. Secondly, the injury mitigating effects of ABS were investigated. The mean RPMI 1+ and RPMI 10+ were analyzed for different crash types. The distributions of impairing injuries (PMI 1+) and severely impairing injuries (PMI 10+) were also analyzed. In the third step, the total reduction of PMI 1+ and PMI 10+ injured motorcyclists was calculated by combining the reductions found in the previous steps. An additional analysis of combined braking systems (CBS) together with ABS was also performed. The results showed that emergency care visits were reduced by 47% with ABS. In the second step, it was found that the mean RPMI 1+ and RPMI 10+ with ABS were 15 and 37% lower, respectively. Finally, the third step showed that the total reductions in terms of crash avoidance and mitigation of PMI 1+ and PMI 10+ injured motorcyclists with ABS were 67 and 55%, respectively. However, PMI 1+ and PMI 10+ leg injuries were not reduced by ABS to the same extent. Indications were found suggesting that the benefits of ABS together with CBS may be greater than ABS alone. This article indicated that motorcycle ABS reduced impairing injuries

We have found thousands of other variants in his genome, including pharmacogenetic and copy number variants. This information has been archived and offered to this person alongside the clinical sequencing data, so that he and others can re-analyze his genome for years to come.Conclusions. To our knowledge, this is the first study in the clinical neurosciences that integrates detailed neuropsychiatric phenotyping, deep brain stimulation for OCD and clinical-grade WGS with management of genetic results in the medical treatment of one person with severe mental illness. We offer this as an example of precision medicine in neuropsychiatry including brain-implantable devices and genomics-guided preventive health care.

    Posthemorrhagic anemia is a rare but important cause of anemia in neonates, second only to hemolytic anemia of newborn. Most cases of posthemorrhagic anemia are reported from fetomaternal hemorrhage or umbilical cord accidents in utero. This case report describes a preterm infant who developed severe anemia and shock immediately after delivery related to an acute hemorrhage through patent umbilical cord vessels secondary to a tear in the umbilical cord at the site of cord clamping. We believe that umbilical cord bleeding from errors in cord clamping could be an important cause of acute blood loss in the delivery room and that it may result in significant clinical morbidity, especially in extremely premature infants.

    Optimum dose, route and duration of use of prophylactic magnesium sulphate in women with severe pre-eclampsia is still controversial. We compared the efficacy and safety of 'low-dose Dhaka' regime with 'Loading dose only' regime for seizure prophylaxis in severe preeclampsia using a randomised controlled trial in 402 women. The incidence of eclampsia in the 'low-dose Dhaka' regime group was 1.49% and that in the 'Loading dose only regime' was 2.98% (p = .321). In the low-dose Dhaka regime, injection site abscess and respiratory depression occurred in one woman each. Neonatal outcomes such as Apgar score at 5 minutes (5.0% vs. 8.05% p = .251) and perinatal mortality (20.4% vs. 21.9%, p = .724) were similar in both groups. Loading dose only regime may be considered an effective alternative regime for the prevention of eclampsia in women with severe preeclampsia. Impact statement What is already known on this subject: Efficacy of therapeutic short regime magnesium sulphate in eclampsia has already been reported. Data regarding prophylactic short regime in women with preeclampsia is sparse. What the results of this study add: We have shown that short regime of magnesium sulphate using only the loading dose in the prevention of seizure in preeclampsia is an effective alternative to the low-dose Dhaka regime. What the implications are of these findings for clinical practice and/or further research: The short regime is less resource-intensive. Further larger studies are needed to confirm the efficacy of this short regime and to establish its cost-effectiveness.

    Accident Management means - generally speaking - all measures taken to 'rectum the plant to a safe state and mitigate the consequences of accidents' in the design basis as well as the beyond design basis realm. Sometimes accident management is interpreted as reforming in particular to those actions which are taken to cope with beyond design basis accidents, i.e. in very unlikely situations. The objectives of the measures depend on the category of the accident: design basis accident: * to keep systems and the plant within the licensed limits beyond design basis accident: * to prevent severe core damage, especially at high pressure in the reactor pressurize vessel and or * to mitigate the consequences of severe accidents for the environment The system use is different: design basis accident: * operation of systems within design limits beyond design basis accident: * best use of all available systems even beyond their design limits assuming best estimate conditions for components and systems. With respect to the different system uses it is expedient to distinguish between measures to control accidents under design basis accident conditions or to manage beyond design basis accidents. The evaluation of a safety concept should give precedence to the systems fundamental roles in the design basis realm. beyond design basis -accident management should be seen as an additional, last-resort tool to cope with scenarios in the beyond design basis realm and should therefore be treated separately as a supplement to the 'normal' design basis measures

    A well-secured endotracheal tube (ETT) is essential for safe anesthesia. The ETT has to be fixed with the adhesive plasters or with tie along with adhesive plasters appropriately. It is specially required in patients having beard, in intensive care unit (ICU) patients or in oral surgeries. If re-adjustment of the ETT is necessary, we should be cautious while removal of the plasters and tie, as there may be damage to the cuff inflation system. This can be a rare cause of ETT cuff leak, thus making maintenance of adequate ventilation difficult and requiring re-intubation. In a difficult airway scenario, it can be extremely challenging to re-intubate again. We report an incidence where the ETT cuff tubing was severed while attempting to re-adjust and re-fix the ETT and the patient required re-intubation. Retrospectively, we thought of and describe a safe, reliable and novel technique to prevent cuff deflation of the severed inflation tube. The technique can also be used to monitor cuff pressure in such scenarios.

    Full Text Available Calcium-containing crystals participate in the pathogenesis of OA. Sodium thiosulfate (STS has been shown to be an effective treatment in calcification disorders such as calciphylaxis and vascular calcification. This study investigated the effects and mechanisms of action of STS in a murine model of OA and in chondrocyte calcification.Hydroxyapatite (HA crystals-stimulated murine chondrocytes and macrophages were treated with STS. Mineralization and cellular production of IL-6, MCP-1 and reactive oxygen species (ROS were assayed. STS's effects on genes involved in calcification, inflammation and cartilage matrix degradation were studied by RT-PCR. STS was administered in the menisectomy model of murine OA, and the effect on periarticular calcific deposits and cartilage degeneration was investigated by micro-CT-scan and histology.In vitro, STS prevented in a dose-dependent manner calcium crystal deposition in chondrocytes and inhibited Annexin V gene expression. In addition, there was a reduction in crystal-induced IL-6 and MCP-1 production. STS also had an antioxidant effect, diminished HA-induced ROS generation and abrogated HA-induced catabolic responses in chondrocytes. In vivo, administration of STS reduced the histological severity of OA, by limiting the size of new periarticular calcific deposits and reducing the severity of cartilage damage.STS reduces the severity of periarticular calcification and cartilage damage in an animal model of OA via its effects on chondrocyte mineralization and its attenuation of crystal-induced inflammation as well as catabolic enzymes and ROS generation. Our study suggests that STS may be a disease-modifying drug in crystal-associated OA.

    Osteoarthritis mainly affects weight-bearing joints such as the hip and knee and is the most common form of arthritis. Greater muscle atrophy with fatty infiltration of gluteal muscles and decreased hip abduction strength has previously been identified with increasing severity of radiological hip OA. However, it is well documented that radiographic findings of OA do not always correlate with clinical severity. The aim of this secondary analysis was to examine whether atrophy and strength of gluteus maximus (GMax), medius (GMed), minimus (GMin), and tensor fascia lata (TFL) is associated with the clinical severity of OA. Twenty participants with unilateral hip OA and 20 age- and sex-matched asymptomatic controls were classified on the basis of clinical severity (mild, moderate-severe and asymptomatic groups) using the Oxford hip score. Muscle volumes of GMax, GMed, GMin, and TFL were determined using magnetic resonance imaging and expressed as asymmetry between limbs. A hand-held dynamometer was used to identify hip rotation and abduction strength. Regression analyzes were used to identify the association between muscle asymmetry and patient-reported severity of hip OA. Both symptomatic groups (mild and moderate-severe) demonstrated significant asymmetry in GMax (P abduction strength was reduced in both symptomatic groups. Gluteal muscle atrophy was associated with the clinical severity of OA. Clinical severity could be a useful tool for clinicians interpreting likely gluteal muscle changes and planning rehabilitation strategies for hip OA patients. Clin.

    The effectiveness of repeated vaccination for influenza to prevent severe cases remains unclear. We evaluated the effectiveness of influenza vaccination on preventing admissions to hospital for influenza and reducing disease severity. We conducted a case-control study in 20 hospitals in Spain during the 2013/14 and 2014/15 influenza seasons. Community-dwelling adults aged 65 years or older who were admitted to hospital for laboratory-confirmed influenza were matched with inpatient controls by sex, age, hospital and admission date. The effectiveness of vaccination in the current and 3 previous seasons in preventing influenza was estimated for inpatients with nonsevere influenza and for those with severe influenza who were admitted to intensive care units (ICUs) or who died. We enrolled 130 inpatients with severe and 598 with nonsevere influenza who were matched to 333 and 1493 controls, respectively. Compared with patients who were unvaccinated in the current and 3 previous seasons, adjusted effectiveness of influenza vaccination in the current and any previous season was 31% (95% confidence interval [CI] 13%-46%) in preventing admission to hospital for nonsevere influenza, 74% (95% CI 42%-88%) in preventing admissions to ICU and 70% (95% CI 34%-87%) in preventing death. Vaccination in the current season only had no significant effect on cases of severe influenza. Among inpatients with influenza, vaccination in the current and any previous season reduced the risk of severe outcomes (adjusted odds ratio 0.45, 95% CI 0.26-0.76). Among older adults, repeated vaccination for influenza was twice as effective in preventing severe influenza compared with nonsevere influenza in patients who were admitted to hospital, which is attributable to the combination of the number of admissions to hospital for influenza that were prevented and reduced disease severity. These results reinforce recommendations for annual vaccination for influenza in older adults. © 2018 Joule Inc. or

    Full Text Available Road trauma is a leading cause of death and injury in young people. Traffic offences are common, but their importance as a risk indicator for subsequent road trauma is unknown. This cohort study assessed whether severe road trauma could be predicted by a history of prior traffic offences.Clinical data of all adult road trauma patients admitted to the Western Australia (WA State Trauma Centre between 1998 and 2013 were linked to traffic offences records at the WA Department of Transport.

    2015-12-01

    Ultraviolet keratitis is caused by the toxic effects of acute high-dose ultraviolet radiation (UVR) reflecting the sensitivity of the ocular surface to photochemical injury. The clinical syndrome presents with ocular pain, tearing, conjunctival chemosis, blepharospasm, and deterioration of vision typically several hours after exposure, lasting up to 3 days. Mountaineers, skiers, and beach recreationalists are particularly at risk to suffer from ultraviolet (UV) keratitis as the reflectivity of UVR in these environments is extremely high. The aim of this review is to raise awareness about the potential of UV damage on the eye with an emphasis on UV keratitis, to highlight the pathophysiological basis of corneal phototoxicity, and to provide practical guidance for the prevention and clinical management of UV keratitis commonly known as snow blindness.

    The clinical implications of thyroid hormones in depression have been studied extensively and still remains disputable. Supplementation of thyroid hormones is considered to augment and accelerate antidepressant treatment. Studies on the role of thyroid hormones in depression deliver contradictory results. Here we assess theirs impact on depression severity and final clinical outcome in patients with major depression. Thyrotropin, free thyroxine (FT4), and free triiodothyronine (FT3) concentrations were measured with automated quantitative enzyme immunoassay. Depression severity and final clinical outcome were rated with 17-itemic Hamilton Rating Scale for Depression [HDRS(17)] and Clinical Global Impression Scales for severity and for improvement (CGIs, CGIi). FT3 and FT4 concentrations were significantly positively correlated with clinical improvement evaluated with CGIi (R = 0.38, P = 0.012; R = 0.33, P = 0.034, respectively). There was a significant correlation between FT4 concentrations and depression severity assessed in HDRS(17) (R = 0.31, P = 0.047). Male patients presented significantly higher FT3 serum levels (Z = 2.34, P = 0.018) and significantly greater clinical improvement (Z = 2.36, P = 0.018) when compared to female patients. We conclude that free thyroid hormones concentrations are associated with depression severity and have an impact on final clinical outcome. It can be more efficient to augment and accelerate the treatment of major depressive disorder with triiodothyronine instead of levothyroxine because of individual differences in thyroid hormones metabolism.

  20. Management of NPP severe accident by prevention of clad-softening

    2015-01-01

    Specified Emergency Core Cooling System (ECCS) flow rate is testimony of clad reaching to temperature lower than its softening temperature during loss of coolant accident (LOCA) in nuclear reactors. Coolant channel(s) of nuclear reactors with vertical fuel-assemblies e. g. LWRs gets voided in a short time as a result of double ended guillotine rupture in coolant pipeline. There is rapid and almost steep rise in clad temperature due to stored energy and decay heat if ECCS flow rate is less than a specified value. A computer program, based on moving mesh methodology, is developed to calculate rewetting velocity. The program is validated using experimental data. Numerical equations are solved by marching technique. The paper will bring out the fact that if coolant flow is less than a specified value the wet front will not reach the top of the clad. This will result some unrewetted clad portion. As the heating of this unrewetted clad is continued it may result softening of clad.

    Full Text Available The aim of the presented paper is a meta-analysis of clinical studies on the comparative effectiveness of pharmaceutical therapy and surgical treatment such as cardiac resynchronization therapy (CRT, cardiac resynchronization therapy with cardioversion-defibrillation (CRT-D, circulatory support system and heart transplantation in patients with severe chronic heart failure (CHF. Material and Methods. Results of 41 clinical studies (29799 patients with severe CHF were included in a meta-analysis. Data search was conducted in the following databases: Medline, Medscape, Pubmed, and websites dedicated to clinical research (National Institutes of Health, Clinical Center, ClinicalStudyResults.org, ClinicalTrials.gov. Results. As compared with pharmaceutical therapy, surgical treatment of severe CHF is better to reduce fatal risk, incidence of decompensation of CHF, frequency of cardiac arrhythmias, the need to perform or re-perform heart transplantation. It is also shown that CRT better reduced the mortality from progression of heart failure than heart transplantation. Both pharmaceutical therapy and surgical treatment improved functional class of CHF and quality of patients' life, but does not affect the left ventricular ejection fraction. Conclusion. It was found out that there was a number of significant advantages of surgical treatment of severe CHF, compared with pharmaceutical therapy. However, it is still a number of unresolved issues (particularly in relation to heart transplantation on the effectiveness comparing pharmaceutical and surgical therapies of severe CHF

    Hospital stays for patients with pressure ulcers (PU) increased nearly 80% from 1992 to 2006. Most PU's developed during an admission, often despite preventive efforts from clinical staff. Data from Electronic medical records (EMR's) were used to prepare daily patient risk factor and PU information for nurses to help prevent PU development and exacerbations. THE OBJECTIVES OF THIS STUDY WERE TO DETERMINE WHETHER: 1) dissemination of an automated daily report with patient risk and current status of pressure ulcers ("PU Daily") helps prevent the development of pressure ulcers, and 2) using the PU Daily information impacts the severity of pressure ulcers that develop in an acute care setting. A pre-post study with four control units was designed to determine the impact of the PU Daily in intensive care units (ICU) in a large medical center. The control units included ICU's using the same EMR and similar complexity of cases with a high risk of developing a PU. The pre-post study took place over a six month period (March - August 2009). A total of 6,735 cases were included in the study. The intervention unit showed a significant decrease (p = 0.004) in PU's at post-evaluation; none of the four comparison units showed a decrease at the pintervention led to a significant reduction in the total number of PU's documented (p intervention with the PU Daily showed a significant decrease in the total PU's and severity of PU's and allowed for implementation of interventions that help prevent the development of PU's. As EMR's become more widely available, this intervention showed a reduction in PU's. Future studies should further develop this intervention and include multiple institutions and patient populations.

Methods: The risk-scoring algorithm for prognostication of scrub typhus severity developed earlier from two general hospitals in Thailand was validated using an independent dataset of scrub typhus patients in one of the hospitals from a few years later. The predictive performances of the two datasets were compared by analysis of the area under the receiver-operating characteristic curve (AuROC. Classification of patients into non-severe, severe, and fatal cases was also compared. Results: The proportions of non-severe, severe, and fatal patients by operational definition were similar between the development and validation datasets. Patient, clinical, and laboratory profiles were also similar. Scores were similar in both datasets, both in terms of discriminating non-severe from severe and fatal patients (AuROC =88.74% versus 91.48%, P=0.324, and in discriminating fatal from severe and non-severe patients (AuROC =88.66% versus 91.22%, P=0.407. Over- and under-estimations were similar and were clinically acceptable. Conclusion: The previously developed risk-scoring algorithm for prognostication of scrub typhus severity performed similarly with the validation data and

    To establish a clinical severity index that correlates severity of body system abnormalities with outcome in dogs with acute pancreatitis (AP) and determine the usefulness of serum C-reactive protein (C-RP) concentration as an objective measure of AP severity. Retrospective cohort study. 61 client-owned dogs with ultrasonographically or histologically confirmed AP. Medical records of AP-affected dogs were reviewed, and signalment, physical examination findings, clinicopathologic data, and outcome (death or discharge from the hospital) were evaluated. The correlation of specific abnormalities in endocrine, hepatic, renal, hematopoietic, cardiovascular, and respiratory systems; local pancreatic complications; and intestinal integrity were evaluated, and a clinical severity index was developed for AP in dogs. The severity index score was compared with outcome and, for 12 dogs, with serum C-RP concentration. The clinical severity index had a good correlation with outcome and interval from hospital admission until end point (days until outcome), but there was no difference in days until outcome between survivors and nonsurvivors. All 12 dogs evaluated had high serum C-RP concentration, but this variable was not related to outcome; however, within a 2-day period after onset of clinical signs, serum C-RP concentration in survivors and nonsurvivors differed significantly. Among AP-affected dogs, the clinical severity index may be useful for treatment comparisons and prediction of intensive management requirements. Serum C-RP concentration was best related to AP severity within a 2-day period after onset of clinical signs, but daily measurement may be more useful for monitoring progress.

    Full Text Available Asthma is the most common chronic disease of childhood. It is known that asthma prevalence has increased significantly especially in children in last 20 years. To stop this increase in asthma, causes and prevention measures should be known better. For the management of the illness, control of environmental and trigger factors causing asthma attack are extremely important. Asthmatic children and family should be informed by health staff about changes in their life and measures to prevent the attacks. Through this information asthmatic children and their families can be supported for a better quality of life. [TAF Prev Med Bull 2010; 9(1.000: 79-86

    To determine (1) the proportion and number of clinically relevant alarms based on the type of monitoring device; (2) whether patient clinical severity, based on the sequential organ failure assessment (SOFA) score, affects the proportion of clinically relevant alarms and to suggest; (3) methods for reducing clinically irrelevant alarms in an intensive care unit (ICU). A prospective, observational clinical study. A medical ICU at the University of Tokyo Hospital in Tokyo, Japan. All patients who were admitted directly to the ICU, aged ≥18 years, and not refused active treatment were registered between January and February 2012. The alarms, alarm settings, alarm messages, waveforms and video recordings were acquired in real time and saved continuously. All alarms were annotated with respect to technical and clinical validity. 18 ICU patients were monitored. During 2697 patient-monitored hours, 11 591 alarms were annotated. Only 740 (6.4%) alarms were considered to be clinically relevant. The monitoring devices that triggered alarms the most often were the direct measurement of arterial pressure (33.5%), oxygen saturation (24.2%), and electrocardiogram (22.9%). The numbers of relevant alarms were 12.4% (direct measurement of arterial pressure), 2.4% (oxygen saturation) and 5.3% (electrocardiogram). Positive correlations were established between patient clinical severities and the proportion of relevant alarms. The total number of irrelevant alarms could be reduced by 21.4% by evaluating their technical relevance. We demonstrated that (1) the types of devices that alarm the most frequently were direct measurements of arterial pressure, oxygen saturation and ECG, and most of those alarms were not clinically relevant; (2) the proportion of clinically relevant alarms decreased as the patients' status improved and (3) the irrelevance alarms can be considerably reduced by evaluating their technical relevance.

    Full Text Available Ulcerative colitis (UC is a chronic inflammation of the coli mucosa clinically characterized by bloody diarrhea, abdominal pain and other systemic symptoms. The onset, as well as subsequent relapses, may occur with varying degrees of clinical and endoscopic activity and extent of disease. The clinical and endoscopic activity varies from mild to severe, while the extent of disease, without interruption, may involve from the rectum up to the entire colon. The severe form, when not properly and promptly treated, can be life-threatening and may determine various complications requiring urgent surgical treatment. Early recognition of severe forms, their treatment and patient monitoring can reduce morbidity and mortality, and improve surgical outcome. Since the 1950s, systemic corticosteroids have been the first-line treatment in severe active UC. Today, appropriate patient monitoring, and recognition of clinical, radiological and laboratory findings indicative of steroid failure guide the clinician in the use of immunomodulatory drugs or suggest indications for surgery. The aim of our study is to review the more recent data and guidelines that could be useful in clinical practice for the management of severe UC.

    To investigate the predictive value of symptoms of dementia that the person or an informant noticed spontaneously in determining the clinical severity of dementia. Cross-sectional. Community-based open-referral dementia assessment service in Hong Kong between 2005 and 2013. Help-seekers for dementia assessment service and their informants (N = 965 dyads). Participants underwent a clinical dementia interview based on the Clinical Dementia Rating. Spontaneous complaints that the person and the informant made that had prompted their help-seeking of groups with interview results suggestive of no impairment, mild cognitive impairment, and dementia were compared. Logistic regression was used to evaluate the predictive value of spontaneous complaints for clinical severity. Independent raters blinded to clinical results coded spontaneously reported symptoms into theoretical themes: memory, executive function, language, time and place orientation, neuropsychiatric, mood, and avolition. Memory problems were the most frequently reported complaints for participants (87.7%) and their informants (95.5%), followed by self-reported language (33.0%) and informant-reported orientation (33.0%) difficulties. Informant-reported but not self-reported symptoms predicted clinical severity. Compared with the persons themselves, informants reported more pervasive symptoms corresponding to clinical severity. Persons with dementia self-reported fewer types of symptoms than their healthy or mildly impaired counterparts. Spontaneously reported language and orientation symptoms by the informant distinguished persons with mild or worse dementia (P < .001, Nagelkerke coefficient of determination = 29.7%, percentage correct 85.6%). The type and pervasiveness of symptoms spontaneously that informants reported predicted clinical severity. This may provide a quick reference for triage. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    To evaluate the correlation between indirect magnetic resonance (MR) arthrographic imaging findings and the clinical symptoms and prognosis of patients with frozen shoulder. Indirect MR arthrography was performed for 52 patients with primary frozen shoulder (mean age 55.1 ± 9.0 years) and 52 individuals without frozen shoulder (mean age 53.1 ± 10.7 years); capsular thickening and enhancement of the axillary recess as well as soft tissue thickening of the rotator interval were evaluated. Clinical symptom severity was assessed using the Visual Analogue Scale for Pain (VAS Pain), simple shoulder test (SST), Constant score, American Shoulder and Elbow Surgeons (ASES) score, and range of motion (ROM). At 6-month follow-up, we evaluated whether MR arthrography findings correlated with the clinical symptoms and prognosis. Capsular thickening and enhancement of the axillary recess as well as soft tissue thickening of the rotator interval were significantly greater in the patient group than in the controls (p < 0.001). Capsular thickening of the axillary recess did not correlate with clinical symptoms or ROM (n.s.); however, capsular enhancement correlated with clinical symptom severity according to VAS Pain (p = 0.005), SST (p = 0.046), and ASES scores (p = 0.009). Soft tissue thickening of the rotator interval did not correlate with clinical symptom severity, but was associated with external rotation limitation (p = 0.002). However, none of the parameters correlated with clinical symptoms at 6-month follow-up. Indirect MR arthrography provided ancillary findings, especially with capsular enhancement, for evaluating clinical symptom severity of frozen shoulder, but did not reflect the prognosis. MR findings in frozen shoulder should not replace clinical judgments regarding further prognosis and treatment decisions. IV.

    Intensive insulin therapy has an inherent risk of hypoglycemia that can lead to loss of consciousness, cardiac arrhythmia, seizure, and death ("dead-in-bed syndrome"). This risk of hypoglycemia is a major concern for patients, families, and physicians. The need for an automated system that can alert in the event of severe hypoglycemia is evident. In engineering systems, where there is a risk of malfunction of the primary control system, alert and safety mechanisms are implemented in layers of protection. This concept has been adopted in the proposed system that integrates a hypoglycemia prediction algorithm with a global position system (GPS) locator and short message service such that the current glucose value with the rate of change (ROC) and the location of the subject can be communicated to a predefined list. Furthermore, if the system is linked to the insulin pump, it can suspend the pump or decrease the basal insulin infusion rate to prevent the pending event. The system was evaluated on clinical datasets of glucose tracings from the DexCom Seven system. Glucose tracings were analyzed for hypoglycemia events and then a text message was broadcast to a predefined list of people who were notified with the glucose value, ROC, GPS coordinates, and a Google map of the location. In addition to providing a safety layer to a future artificial pancreas, this system also can be easily implemented in current continuous glucose monitors to help provide information and alerts to people with diabetes.

    In light of the known associations between stress, negative affect, and relapse, mindfulness strategies hold promise as a means of reducing relapse susceptibility. In a pilot randomized clinical trial, we evaluated the effects of Mindfulness Based Relapse Prevention (MBRP), relative to a health education control condition (HE) among stimulant dependent adults receiving contingency management. All participants received a 12-week contingency management (CM) intervention. Following a 4-week CM-only lead in phase, participants were randomly assigned to concurrently receive MBRP (n=31) or HE (n=32). Stimulant dependent adults age 18 and over. A university based clinical research center. The primary outcomes were stimulant use, measured by urine drug screens weekly during the intervention and at 1-month post-treatment, negative affect, measured by the Beck Depression Inventory and Beck Anxiety Inventory, and psychiatric severity, measured by the Addiction Severity Index. Medium effect sizes favoring MBRP were observed for negative affect and overall psychiatric severity outcomes. Depression severity changed differentially over time as a function of group, with MBRP participants reporting greater reductions through follow-up (p=0.03; Effect Size=0.58). Likewise, the MBRP group evidenced greater declines in psychiatric severity, (p=0.01; Effect Size=0.61 at follow-up). Among those with depressive and anxiety disorders, MBRP was associated with lower odds of stimulant use relative to the control condition (Odds Ratio= 0.78, p=0.03 and OR=0.68, p=0.04). MBRP effectively reduces negative affect and psychiatric impairment, and is particularly effective in reducing stimulant use among stimulant dependent adults with mood and anxiety disorders.

    To evaluate long-term outcomes on efficacy and safety of severe uveitic glaucoma treated with a Baerveldt glaucoma implant (BGI). A retrospective study of 47 eyes of 47 patients with uveitic glaucoma treated by a BGI between September 2002 and September 2015. Main outcome measures were intraocular pressure (IOP), number of glaucoma medications, course of the uveitis, visual acuity (VA) and complications. Mean IOP dropped from 30.6 ± 8.1 mmHg with 3.6 ± 1.1 glaucoma medications at baseline to 10.6 ± 4.3 mmHg with 1.0 ± 1.3 glaucoma medications after a mean follow-up of 63.6 ± 43.1 months. In the majority of cases, IOP remained stable during follow-up. However, especially in several patients with viral uveitis, episodes with IOP peaks were observed during a flare-up despite a functioning implant. These peaks remained below preoperative levels. During follow-up, 16 patients (34%) experienced a clinically significant VA loss, mainly because of late-stage glaucoma or hypotony maculopathy. Early postoperative complications were transient choroidal effusion (n = 5), shallow/flat anterior chamber (n = 4), hyphaema (n = 2) and suprachoroidal haemorrhage (n = 1). The most important late postoperative complication was hypotony maculopathy (n = 5), three of these in juvenile idiopathic arthritis (JIA) patients. The BGI is an effective and safe treatment for patients with refractive secondary glaucoma due to uveitis. In a majority of patients, VA remains stable and a low and stable IOP is maintained over time with an acceptable number of complications. In particular, patients with viral uveitis and glaucoma should be closely monitored for IOP peaks that may occur during episodes of a flare-up of uveitis, whereas at the other end of the spectrum, patients with JIA seem much more prone to hypotony maculopathy. © 2017 Acta Ophthalmologica Scandinavica Foundation.

    Allergen exposure in sensitized individuals with asthma interacts with viruses to increase the risk of asthma exacerbation. To evaluate the use of house dust mite-impermeable bedding and its impact on severe asthma exacerbations in children. We randomized mite-sensitized children with asthma (ages 3-17 yr) after an emergency hospital attendance with an asthma exacerbation to receive mite-impermeable (active group) or control (placebo group) bed encasings. Over a 12-month intervention period, the occurrence of severe asthma exacerbations was investigated. Of 434 children with asthma who consented, 286 (mean age, 7.7 yr; male sex, 65.8%) were mite sensitized, and 284 were randomized (146 to the active group and 138 to the placebo group). At 12 months, significantly fewer children in the active group than in the placebo group had attended the hospital with an exacerbation (36 [29.3%] of 123 vs. 49 [41.5%] of 118; P = 0.047). In the multivariable analysis, the risk of emergency hospital attendance was 45% lower in the active group (hazard ratio, 0.55; 95% confidence interval [CI], 0.36-0.85; P = 0.006) than in the placebo group. The annual rate of emergency hospital attendance with exacerbations was 27% lower in the active group than in the placebo group, but this did not reach significance (estimated marginal mean [95% CI], active, 0.38 [0.26-0.56] vs. placebo, 0.52 [0.35-0.76]; P = 0.18). No difference between the groups in the risk of prednisolone use for exacerbation was found (hazard ratio, 0.82; 95% CI, 0.58-1.17; P = 0.28). Mite-impermeable encasings are effective in reducing the number of mite-sensitized children with asthma attending the hospital with asthma exacerbations but not the number requiring oral prednisolone. This simple measure may reduce the health care burden of asthma exacerbations in children. Clinical trial registered with www.isrctn.com (ISRCTN 69543196).

    Objective: To understand the characteristics and relation of clinical stage and outcome of severe cases on hand, foot and mouth disease (HFMD) and to establish the evaluation method for understanding severity of this disease. Methods: According to factors as geographical location, economic and epidemic levels, five provinces (Henan, Shandong, Yunnan, Zhejiang and Sichuan provinces) were selected. Reported severe cases of HFMD from the National Notifiable Diseases Reporting System were selected randomly in the five provinces. Basic epidemiological information, clinical data, and pathogen testing results in the involved hospitals were collected. Clinical stages on all the patients were decided in accordance with"the clinical expert consensus on diagnosis and treatment for severe case of enterovirus type 71 (EV71) infections (2011 edition)" . Data were analyzed using SPSS software 18.0 and other epidemiological methods. Results: A total of657 severe HFMD cases were investigated, with 326 cases positive of EV71, accounting for 91.3 % (326/357) among all the laboratory-confirmed cases. Of the 657 cases, 542 cases (82.5 % , 95 %CI : 79.4 %- 85.3 % ) were diagnosed as in stage 2 (with nervous system involvement), 99 cases (15.1 % , 95 %CI : 12.4 %- 18.0 % ) in stage 3 (early phase of function failure on heart and lung), and 16 cases (2.4 % , 95 %CI : 1.4 %- 3.9 % ) were in stage 4 (function failure of heart and lung). 11 cases (1.7 % , 95 %CI : 0.9 %- 3.0 % ) were with squeal when discharged from hospital with 8 cases (1.2 % , 95 %CI : 0.6 %- 2.3 % ) died. When comparing the proportions among stage 2, stage 3 and stage 4, significant differences were found between age groups ( χ (2)=22.632, P =0.012). The younger the patient was the lower the proportions of stage 2 and the more proportion of stage 3 appeared. When comparing the proportions of clinical stages among the five provinces, significant differences ( χ (2)=41.481, P =0.000) were noticed. Proportions of

    Among all the types of accidents to be considered for the safety licensing of a plant, some have a very low probability of occurrence but might have very important consequences: the severe accidents or Hypothetical Core Disruptive Accidents (HCDA). The studies on the scenario of these accidents are performed in parallel to the prevention studies. In this PhD report, two representative safety cases are studied: the Unprotected Loss Of Flow (ULOF) and the Total Instantaneous Blockage (TIB). The objectives are to understand what causes the reactivity increase during these accidents and to find means to reduce the energetic release of the scenario (ULOF) or to find ways to trigger the core prior to the propagation of the accident (TIB). At first, the accidents are studied in static calculations with the ERANOS code system. The accidents are divided into several steps and the reactivity insertions at each step are explained. This study shows the importance of the removal of the structures as well as of the radial leakage changes during the core slumping-down. The study also gives the amounts of fuel to be ejected or of absorber to be injected in both accidents. These values give tracks to the following more accurate studies, the transient studies. The transient studies were performed with the SIMMER code system, coupling thermo-hydraulics and neutronics. SIMMER data and algorithms have been improved so as to better predict ERANOS results (former discrepancies were up to 1.5$). The SIMMER reactivity calculation is improved by 0.8$ with variations of reactivity due to the motion of materials correctly predicted. A new algorithm for the β-effective was implemented in SIMMER so as to be more accurate and easier to manage. SIMMER is then used to calculate the secondary phase of the ULOF, while the primary phase is calculated with ERANOS thanks to some assumptions. The assumptions are very much based on the fact that the movement of materials stops whenever the energy

    Dengue is a potentially life-threatening illness, and children are at higher risk of severity. This review aimed to systematize the identified clinical and laboratory parameters associated with severe dengue in children, as monitoring these signs and fluid-replacement therapy are actually the cornerstones of dengue treatment. Of the 527 studies initially reviewed, 21 were selected as follows: three cohort studies, three case-control studies, 14 cross-sectional studies and one not defined. Eighteen studies were carried out in Asia and three in the Americas. Hepatomegaly, lethargy, abdominal pain, bleeding, hemoconcentration and thrombocytopenia, all referenced as warning signs in the WHO 2009 Guidelines, were the clinical and laboratory parameters independently associated with severity in more than one study. The recognition of these known warning signs associated to severe dengue disease underlines the usefulness of the WHO 2009 classification.

    Human cytomegalovirus (CMV) is under-recognised, despite being the leading infectious cause of congenital malformation, affecting ~0.3% of Australian live births. Approximately 11% of infants born with congenital CMV infection are symptomatic, resulting in clinical manifestations, including jaundice, hepatosplenomegaly, petechiae, microcephaly, intrauterine growth restriction and death. Congenital CMV infection may cause severe long-term sequelae, including progressive sensorineural hearing loss and developmental delay in 40-58% of symptomatic neonates, and ~14% of initially asymptomatic infected neonates. Up to 50% of maternal CMV infections have nonspecific clinical manifestations, and most remain undetected unless specific serological testing is undertaken. The combination of serology tests for CMV-specific IgM, IgG and IgG avidity provide improved distinction between primary and secondary maternal infections. In pregnancies with confirmed primary maternal CMV infection, amniocentesis with CMV-PCR performed on amniotic fluid, undertaken after 21-22 weeks gestation, may determine whether maternofetal virus transmission has occurred. Ultrasound and, to a lesser extent, magnetic resonance imaging are valuable tools to assess fetal structural and growth abnormalities, although the absence of fetal abnormalities does not exclude fetal damage. Diagnosis of congenital CMV infection at birth or in the first 3 weeks of an infant's life is crucial, as this should prompt interventions for prevention of delayed-onset hearing loss and neurodevelopmental delay in affected infants. Prevention strategies should also target mothers because increased awareness and hygiene measures may reduce maternal infection. Recognition of the importance of CMV in pregnancy and in neonates is increasingly needed, particularly as therapeutic and preventive interventions expand for this serious problem. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    This study tested the new DSM-5 severity criterion for binge eating disorder (BED) based on frequency of binge-eating in a clinical sample. This study also tested overvaluation of shape/weight as an alternative severity specifier. Participants were 834 treatment-seeking adults diagnosed with DSM-5 BED using semi-structured diagnostic and eating-disorder interviews. Participants sub-grouped based on DSM-5 severity levels and on overvaluation of shape/weight were compared on demographic and clinical variables. Based on DSM-5 severity definitions, 331 (39.7%) participants were categorized as mild, 395 (47.5%) as moderate, 83 (10.0%) as severe, and 25 (3.0%) as extreme. Analyses comparing three (mild, moderate, and severe/extreme) severity groups revealed no significant differences in demographic variables or body mass index (BMI). Analyses revealed significantly higher eating-disorder psychopathology in the severe/extreme than moderate and mild groups and higher depression in moderate and severe/extreme groups than the mild group; effect sizes were small. Participants characterized with overvaluation (N = 449; 54%) versus without overvaluation (N = 384; 46%) did not differ significantly in age, sex, BMI, or binge-eating frequency, but had significantly greater eating-disorder psychopathology and depression. The robustly greater eating-disorder psychopathology and depression levels (medium-to-large effect sizes) in the overvaluation group was observed without attenuation of effect sizes after adjusting for ethnicity/race and binge-eating severity/frequency. Our findings provide support for overvaluation of shape/weight as a severity specifier for BED as it provides stronger information about the severity of homogeneous groupings of patients than the DSM-5 rating based on binge-eating.

    This paper examines the role of clinical practitioners and clinical researchers internationally in establishing the utility of harm-reduction approaches to substance use. It thus illustrates the potential for clinicians to play a pivotal role in health promoting structural interventions based on harm-reduction goals and public health models. Popular media images of drug use as uniformly damaging, and abstinence as the only acceptable goal of treatment, threaten to distort clinical care away from a basis in evidence, which shows that some ways of using drugs are far more harmful than others and that punitive approaches and insistence on total abstinence as the only goal of treatment often increases the harms of drug use rather than reducing drug use. Therefore the leadership and scientific authority of clinicians who understand the health impact of harm-reduction strategies is needed. Through a review of harm-reduction interventions in Canada, the United Kingdom, the United States, Australia, Switzerland, and the Netherlands, we identify three ways that clinicians have helped to achieve a paradigm shift from punitive approaches to harm-reduction principles in clinical care and in drug policy: (1) through clinical research to provide data establishing the effectiveness and feasibility of harm-reduction approaches, (2) by developing innovative clinical programmes that employ harm reduction, and thereby (3) changing the standard of care to include routine use of these evidence-based (but often misunderstood) approaches in their practices. We argue that through promotion of harm-reduction goals and methods, clinicians have unique opportunities to improve the health outcomes of vulnerable populations.

    Background Osgood–Schlatter disease (OSD) is one of the common causes of knee pain in active adolescents who play sports. The common age for boys to have OSD is between 12 and 15 years and for girls, between 8 and 12 years. Radiographic studies are helpful in diagnosis and treatment of OSD. Purpose We examine the age at onset of OSD in detail and investigate the relationship between clinical findings, radiographic bone morphology, and the severity of OSD in adolescents. Results The average age at onset of knee pain was 12 years and 6 months – 12 years and 9 months in boys, and 12 years and 1 month in girls. Boys were significantly older than girls at onset. In addition, there were significant relationships between duration from first onset to visit to the clinic, radiographic bone stage, body morphology, and radiographic severity. The patients who delayed their visit to the clinic from the first onset of pain and who were older showed a later bone stage and more radiographic severity grade of OSD. There was significant differences concerning weight and body mass index between severity grade I and III. Conclusion For the age at the onset of OSD, the mean age of boys was significantly older than that of girls. The patients at a later bony stage had a higher severity grade. The boys and girls with OSD who had less weight or body mass index showed less severity. PMID:24198582

    Dengue has become a major global public health threat with almost half of the world's population living in at-risk areas. Vaccination would likely represent an effective strategy for the management of dengue disease in endemic regions, however to date there is only one licensed preventative vaccine for dengue infection. The development of a vaccine against dengue virus (DENV) has been hampered by an incomplete understanding of protective immune responses against DENV. The most clinically advanced dengue vaccine is the chimeric yellow fever-dengue vaccine (CYD) that employs the yellow fever virus 17D strain as the replication backbone (Chimerivax-DEN; CYD-TDV). This vaccine had an overall pooled protective efficacy of 65.6% but was substantially more effective against severe dengue and dengue hemorrhagic fever. Several other vaccine approaches have been developed including live attenuated chimeric dengue vaccines (DENVax and LAV Delta 30), DEN protein subunit V180 vaccine (DEN1-80E) and DENV DNA vaccines. These vaccines have been shown to be immunogenic in animals and also safe and immunogenic in humans. However, these vaccines are yet to progress to phase III trials to determine their protective efficacy against dengue. This review will summarize the details of vaccines that have progressed to clinical trials in humans.

    In 2008, the UK National Osteoporosis Guideline Group (NOGG) produced a guideline on the prevention and treatment of osteoporosis, with an update in 2013. This paper presents a major update of the guideline, the scope of which is to review the assessment and management of osteoporosis and the prevention of fragility fractures in postmenopausal women and men age 50 years or over. Where available, systematic reviews, meta-analyses and randomised controlled trials were used to provide the evidence base. Conclusions and recommendations were systematically graded according to the strength of the available evidence. Review of the evidence and recommendations are provided for the diagnosis of osteoporosis, fracture-risk assessment, lifestyle measures and pharmacological interventions, duration and monitoring of bisphosphonate therapy, glucocorticoid-induced osteoporosis, osteoporosis in men, postfracture care and intervention thresholds. The guideline, which has received accreditation from the National Institute of Health and Care Excellence (NICE), provides a comprehensive overview of the assessment and management of osteoporosis for all healthcare professionals who are involved in its management.

  13. Preventing medico-legal issues in clinical practice

    Full Text Available The medical profession is considered to be one of the noblest professions in the world. The practice of medicine is capable of rendering noble service to humanity provided due care, sincerity, efficiency, and professional skill is observed by the doctors. However, today, the patient–doctor relationship has almost diminished its fiduciary character and has become more formal and structured. Doctors are no longer regarded as infallible and beyond questioning. Corporatization of health care has made it like any other business, and the medical profession is increasingly being guided by the profit motive rather than that of service. On the other hand, a well-publicized malpractice case can ruin the doctor's career and practice. The law, like medicine, is an inexact science. One cannot predict with certainty an outcome of cases many a time. It depends on the particular facts and circumstances of the case, and also the personal notions of the judge concerned who is hearing the case. The axiom “you learn from your mistakes” is too little honored in healthcare. The best way to handle medico-legal issues is by preventing them, and this article tries to enumerate the preventive measures in safeguarding the doctor against negligence suit.

  14. New concepts and challenges in the clinical translation of cancer preventive therapies: the role of pharmacodynamic biomarkers.

    Science.gov (United States)

    Brown, Karen; Rufini, Alessandro

    2015-01-01

    Implementation of therapeutic cancer prevention strategies has enormous potential for reducing cancer incidence and related mortality. Trials of drugs including tamoxifen and aspirin have led the way in demonstrating proof-of-principle that prevention of breast and colorectal cancer is feasible. Many other compounds ranging from drugs in widespread use for various indications, including metformin, bisphosphonates, and vitamin D, to dietary agents such as the phytochemicals resveratrol and curcumin, show preventive activity against several cancers in preclinical models. Notwithstanding the wealth of opportunities, major challenges have hindered the development process and only a handful of therapies are currently approved for cancer risk reduction. One of the major obstacles to successful clinical translation of promising preventive agents is a lack of pharmacodynamic biomarkers to provide an early read out of biological activity in humans and for optimising doses to take into large scale randomised clinical trials. A further confounding factor is a lack of consideration of clinical pharmacokinetics in the design of preclinical experiments, meaning results are frequently reported from studies that use irrelevant or unachievable concentrations. This article focuses on recent findings from investigations with dietary-derived agents to illustrate how a thorough understanding of the mechanisms of action, using models that mimic the clinical scenario, together with the development of compound-specific accompanying pharmacodynamic biomarkers could accelerate the developmental pipeline for preventive agents and maximise the chances of success in future clinical trials. Moreover, the concept of a bell-shaped dose-response curve for therapeutic cancer prevention is discussed, along with the need to rethink the traditional 'more is better' approach for dose selection.

    This cross-sectional study assessed the impact of clinical epilepsy severity and pretreatment hypsarrhythmia severity on epilepsy and cognitive outcomes in treated children with West syndrome. Thirty-three children, aged 1 to 5 years, with infantile spasms were enrolled if pretreatment EEG records were available, after completion of ≥1 year of onset of spasms. Neurodevelopment was assessed by Development Profile 3 and Gross Motor Function Classification System. Epilepsy severity in the past 1 year was determined by the Early Childhood Epilepsy Severity Score (E-Chess). Kramer Global Score of hypsarrhythmia severity was computed. Kramer Global Score (≤8) and E-Chess (≤9) in the past 1 year were associated with favorable epilepsy outcome but not neurodevelopmental or motor outcome.

    Influenza-Like Illness is a leading cause of hospitalization in children. Disease burden due to influenza and other respiratory viral infections is reported on a population level, but clinical scores measuring individual changes in disease severity are urgently needed. Areas covered: We present a composite clinical score allowing individual patient data analyses of disease severity based on systematic literature review and WHO-criteria for uncomplicated and complicated disease. The 22-item ViVI Disease Severity Score showed a normal distribution in a pediatric cohort of 6073 children aged 0-18 years (mean age 3.13; S.D. 3.89; range: 0 to 18.79). Expert commentary: The ViVI Score was correlated with risk of antibiotic use as well as need for hospitalization and intensive care. The ViVI Score was used to track children with influenza, respiratory syncytial virus, human metapneumovirus, human rhinovirus, and adenovirus infections and is fully compliant with regulatory data standards. The ViVI Disease Severity Score mobile application allows physicians to measure disease severity at the point-of care thereby taking clinical trials to the next level.

    The clinical performance of enamel microabrasion alone for aesthetic management of dental fluorosis is debatable. This study aimed to compare the clinical efficacy of enamel microabrasion for the aesthetic management of mild-to-severe dental fluorosis. A total of 154 fluorosed incisors and canines in 14 patients on the basis of the fluorosis were included; the teeth were classified as mild (group I, n = 53), moderate (group II, n = 56), and severe (group III, n = 45). All teeth were treated with enamel microabrasion (Opalustre, Ultradent Products, South Jordan, UT, USA). "Improvement in appearance," "changes in brown stains," "changes in opaque white areas," and "requirement for further treatments" were assessed by using visual scale systems. The data were analyzed using nonparametric tests (α = 0.05). The "improvement in appearance" score was the worst for group III (p white areas" score was the best for group I (p stains." The proportion of patients who needed further treatment was the highest in Group III (p stains. Increase in fluorosis severity led to increased requirements for further treatments. The clinical performance of enamel microabrasion is affected by the severity of dental fluorosis, except for its performance of removing brown stains. Even though its performance of improving appearance decreases with the increase in severity of fluorosis, it may not only remove the fluorosis stains but also may increase the success of additional subsequent treatment. © 2013 Wiley Periodicals, Inc.

    To analyze the clinical features of acute intra-operative encephalocele and the proper prophylactic-therapeutic measures for severe craniocerebral injury. The clinical data were collected and analyzed for 21 patients with severe head injuries who suffered acute intra-operative encephalocele from June 2008 to May 2010. There were 12 males and 9 females with an age range of 18 - 69 years old. Among these patients, 6 died with a mortality rate of 28.5%. It was lower than that reported in literatures. One patient died post-operatively of severe brain swelling and intracranial infection secondary to leakage of cerebrospinal fluid. Four patients died of severe craniocerebral injury, brain swelling and brain stem failure. And 1 patient died after his guardian abandoned the treatment. The follow-up period for the remaining 15 surviving patients was 3 - 6 months. According to the Glasgow outcome score (GOS), there were a favorable prognosis (n = 9), moderate disabilities (n = 5) and severe disability (n = 1). The probability of acute intra-operative encephalocele may be predicted in advance with a combination of clinical features and computed tomographic scans. The therapeutic success rate of acute encephalocele will be boosted by taking protective and therapeutic measures pre- and intra-operatively.

    To explore the clinical characteristics of various types of severe drug eruption and common sensitized drugs, and to provide clinical references for reducing the incidence of severe drug eruption.
 Methods: The clinical data regarding 126 cases of severe drug eruption were analyzed retrospectively from June 2009 to May 2017 in Xiangya Hospital, Central South University.
 Results: In the 126 cases of severe drug eruption, the distribution of men and women ratio was 1:1.38. The length of stay was (12.7±9.8) d. The most common type was Steven-Johnson syndrome; the most dangerous type was drug-induced bullosa epidermolysis. The most common sensitized drug category in these patients was antibiotics; the most common single sensitizing drug was carbamazepine, following by allopurinol.
 Conclusion: Severe drug eruption occurs mostly in young and middle-aged people. Steven-Johnson syndrome is the most common type; drug hypersensitive syndrome has the longest length of hospital course. Mortality rate of drug-induced bullosa epidermolysis is the highest. Timely stop using of allergens, early using glucocorticoids, and timely combination of non-glucocorticoids treatment (such as intravenous immunogloblin, plasma exchange and hemodialysis), can improve the efficacy and reduce the complications and mortality.

    Purpose Retroillumination photography analysis (RPA) provides objective assessment of the number and distribution of guttae in Fuchs Corneal Dystrophy. Here, we assess its correlation with clinical grading using slit-lamp biomicroscopy across varying levels of severity. Methods Retroillumination photographs were conducted of 95 affected corneas with slit-lamp flash photography after pupillary dilation. Individual guttae were counted manually and the position of individual points recorded. Clinical grading using the Krachmer scale was documented for each eye during examination, and regression analyses were performed to identify the strength of association with number of guttae. We assessed range at each stage of clinical grading, and utilized the Mann-Whitney U test to assess whether clinical grading levels demonstrated successively higher numbers of guttae. Results Krachmer score ranged from 1 to 5, with mean of 2.6. Mean numbers of guttae at each level of severity were 289 (1+), 999 (2+), 2669 (3+), 5474 (4+), and 7133 (5+). Each stage demonstrated significantly higher numbers of guttae than its preceding level except from 4+ to 5+ (p=0.30), consistent with the definition of 4+ as the highest level defined by presence of guttae. Higher levels of clinical grading were associated with larger ranges of guttae (p<0.01). A linear regression model resulted in a strong fit between RPA and Krachmer score (r=0.81). Conclusion In this largest study of RPA data and comparison with subjective clinical grading of FCD severity, RPA correlates strongly and demonstrates enhanced definition of severity at advanced stages of disease.

    Although certain risk factors can identify individuals who are most likely to develop chronic pain, few interventions to prevent chronic pain have been identified. To facilitate the identification of preventive interventions, an IMMPACT meeting was convened to discuss research design considerations for clinical trials investigating the prevention of chronic pain. We present general design considerations for prevention trials in populations that are at relatively high risk for developing chronic pain. Specific design considerations included subject identification, timing and duration of treatment, outcomes, timing of assessment, and adjusting for risk factors in the analyses. We provide a detailed examination of 4 models of chronic pain prevention (i.e., chronic post-surgical pain, postherpetic neuralgia, chronic low back pain, and painful chemotherapy-induced peripheral neuropathy). The issues discussed can, in many instances, be extrapolated to other chronic pain conditions. These examples were selected because they are representative models of primary and secondary prevention, reflect persistent pain resulting from multiple insults (i.e., surgery, viral infection, injury, and toxic/noxious element exposure), and are chronically painful conditions that are treated with a range of interventions. Improvements in the design of chronic pain prevention trials could improve assay sensitivity and thus accelerate the identification of efficacious interventions. Such interventions would have the potential to reduce the prevalence of chronic pain in the population. Additionally, standardization of outcomes in prevention clinical trials will facilitate meta-analyses and systematic reviews and improve detection of preventive strategies emerging from clinical trials.

    Full Text Available Personality disorders are common in subjects with panic disorder. Personality disorders have shown to affect the course of panic disorder. The purpose of this study was to examine which personality disorders effect clinical severity in subjects with panic disorder. This study included 122 adults (71 female, 41 male, who met DSM-IV criteria for panic disorder (with or without agoraphobia. Clinical assessment was conducted by using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I, the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II and the Panic and Agoraphobia Scale (PAS, Global Assessment Functioning Scale (GAF, Beck Depression Inventory (BDI, and State-Trait Anxiety Inventory (STAI. Patients who had a history of sexual abuse were assessed with Sexual Abuse Severity Scale. Logistic regressions were used to identify predictors of suicide attempts, suicidal ideation, agoraphobia, different panic attack symptoms, sexual abuse, and early onset of disorders. The rates of comorbid Axis I and Axis II psychiatric disorders were 80.3% and 33.9%, consecutively, in patients with panic disorder. Panic disorder patients with comorbid personality disorders had more severe anxiety, depression and agoraphobia symptoms, and had earlier ages of onset, and lower levels of functioning. The rates of suicidal ideation and suicide attempts were 34.8% and 9.8%, consecutively, in subjects with panic disorder. The rate of patients with panic disorder had a history of childhood sexual abuse was 12.5%. The predictor of sexual abuse was more than one comorbid Axis II diagnosis. The predictors of suicide attempt were comorbid paranoid and borderline personality disorders, and the predictor of suicidal ideation was major depressive disorder in subjects with panic disorder. In conclusion, this study documents that comorbid personality disorders increase the clinical severity of panic disorder. Patients with more than one

    Full Text Available Abstract Background Malaria and Tuberculosis (TB are important causes of morbidity and mortality in Africa. Malaria prevention reduces mortality among HIV patients, pregnant women and children, but its role in TB patients is not clear. In the TB National Reference Center in Guinea-Bissau, admitted patients are in severe clinical conditions and mortality during the rainy season is high. We performed a three-step malaria prevention program to reduce mortality in TB patients during the rainy season. Methods Since 2005 Permethrin treated bed nets were given to every patient. Since 2006 environmental prevention with permethrin derivates was performed both indoor and outdoor during the rainy season. In 2007 cotrimoxazole prophylaxis was added during the rainy season. Care was without charge; health education on malaria prevention was performed weekly. Primary outcomes were death, discharge, drop-out. Results 427, 346, 549 patients were admitted in 2005, 2006, 2007, respectively. Mortality dropped from 26.46% in 2005 to 18.76% in 2007 (p-value 0.003, due to the significant reduction in rainy season mortality (death/discharge ratio: 0.79, 0.55 and 0.26 in 2005, 2006 and 2007 respectively; p-value 0.001 while dry season mortality remained constant (0.39, 0.37 and 0.32; p-value 0.647. Costs of malaria prevention were limited: 2€/person. No drop-outs were observed. Health education attendance was 96-99%. Conclusions Malaria prevention in African tertiary care hospitals seems feasible with limited costs. Vector control, personal protection and cotrimoxazole prophylaxis seem to reduce mortality in severely ill TB patients. Prospective randomized trials are needed to confirm our findings in similar settings. Trial registration number Current Controlled Trials: ISRCTN83944306

    Full Text Available Dengue virus is endemic in tropical and sub-tropical resource-poor countries. Dengue illness can range from a nonspecific febrile illness to a severe disease, Dengue Shock Syndrome (DSS, in which patients develop circulatory failure. Earlier diagnosis of severe dengue illnesses would have a substantial impact on the allocation of health resources in endemic countries.We compared clinical laboratory findings collected within 72 hours of fever onset from a prospective cohort children presenting to one of two hospitals (one urban and one rural in Thailand. Classification and regression tree analysis was used to develop diagnostic algorithms using different categories of dengue disease severity to distinguish between patients at elevated risk of developing a severe dengue illness and those at low risk. A diagnostic algorithm using WBC count, percent monocytes, platelet count, and hematocrit achieved 97% sensitivity to identify patients who went on to develop DSS while correctly excluding 48% of non-severe cases. Addition of an indicator of severe plasma leakage to the WHO definition led to 99% sensitivity using WBC count, percent neutrophils, AST, platelet count, and age.This study identified two easily applicable diagnostic algorithms using early clinical indicators obtained within the first 72 hours of illness onset. The algorithms have high sensitivity to distinguish patients at elevated risk of developing severe dengue illness from patients at low risk, which included patients with mild dengue and other non-dengue febrile illnesses. Although these algorithms need to be validated in other populations, this study highlights the potential usefulness of specific clinical indicators early in illness.

    Physical inactivity and sedentary time are distinct behaviors that may be more prevalent in severe asthma, contributing to poor disease outcomes. Physical activity and sedentary time in severe asthma however have not been extensively examined. We aimed to objectively measure physical activity and sedentary time in people with severe asthma compared with age-matched control participants, describing the associations of these behaviors with clinical and biological outcomes. We hypothesized that people with severe asthma would be less active and more sedentary. In addition, more activity and less sedentary time would be associated with better clinical outcomes and markers of systemic and airway inflammation in people with severe asthma. Adults with severe asthma (n = 61) and sex- and age-matched controls (n = 61) underwent measurement of lung function, exercise capacity, asthma control, health status, and airway and systemic inflammation. Physical activity and sedentary time were measured using an accelerometer. The severe asthma and control groups were matched in terms of age and sex (32 [53%] females in each group). Individuals with severe asthma accumulated less minutes per day in moderate and higher intensity activity, median (IQR) 21.9 (12.9-36.0) versus 41.7 (29.5-65.2) (P exercise capacity in participants with severe asthma (coefficient, 0.0169; 95% CI, 0.008-0.025; P asthma perform less moderate and vigorous activity than do controls. Higher levels of activity and lower levels of sedentary time are associated with better exercise capacity, asthma control, and lower levels of systemic inflammation.

    Full Text Available Farnaz Tabatabaian, Dennis K Ledford Division of Allergy and Immunology, Department of Internal Medicine, Morsani College of Medicine, University of South Florida, Tampa, FL, USA Abstract: Asthma is a heterogeneous syndrome with numerous underlining molecular and inflammatory mechanisms contributing to the wide spectrum of clinical phenotypes. Multiple therapies targeting severe asthma with type 2 (T2 high inflammation are or soon will be available. T2 high inflammation is defined as inflammation associated with atopy or eosinophilia or an increase in cytokines associated with T-helper 2 lymphocytes. Omalizumab is a humanized anti-IgE monoclonal antibody and the first biologic therapy approved for moderate–severe allergic asthma. Despite the specificity of biologic therapies like omalizumab, clinical response is variable, with approximately 50% of treated patients achieving the primary outcome. A prior identification of the ideal candidate for therapy would improve patient outcomes and optimize the use of health care resources. As the number of biologic therapies for asthma increases, the goal is identification of biomarkers or clinical phenotypes likely to respond to a specific therapy. This review focuses on potential biomarkers and clinical history that may identify responders to omalizumab therapy for asthma.

    To investigate the nutritional risk in children with severe pneumonia using the Screening Tool for the Assessment of Malnutrition in Paediatrics (STAMP) and the association between nutritional risk and adverse clinical outcomes. According to the STAMP score, 216 children with severe pneumonia were classified into high nutritional risk group (HR group; n=98), moderate nutritional risk group (MR group; n=65), and low nutritional risk group (LR group; n=53). Fasting blood samples were collected to measure the levels of insulin-like growth factor-1 (IGF-1), adiponectin, leptin, non-esterified fatty acid (NEFA), albumin, transferrin, prealbumin, and retinol binding protein (RBP). The adverse clinical outcomes were recorded. Compared with the MR and LR groups, the HR group had significantly lower serum levels of IGF-1, leptin, adiponectin, prealbumin, and RBP, as well as a significantly higher serum level of NEFA (Prisk screening has an important value in evaluating the clinical outcome of children with severe pneumonia, and children at a higher nutritional risk tend to have more adverse clinical outcomes.

    In both humans and dogs the pulmonary vasculature is able to recruit large-diameter anatomical intrapulmonary arteriovenous anastomoses (IPAVAs). In healthy people the opening of these anastomoses affects the degree of exercise-induced increase in pulmonary arterial pressure. The presence of these IPAVAs can be demonstrated using saline contrast echocardiography. The aims of the present study were to characterize severely affected, naturally infected dogs with Angiostrongylus vasorum, to evaluate if these dogs can open IPAVAs, and to assess if the recruitment of such anastomoses affects the severity of pulmonary hypertension (PH). Eight client-owned dogs with severe A. vasorum infection were recruited. Dogs with A. vasorum infection that presented with severe dyspnea and/or syncope were prospectively screened by echocardiography for the presence of PH and IPAVAs. Only severely affected dogs, based on a combination of clinical, radiographic and echocardiographic abnormalities, were enrolled. Opening of IPAVAs could be demonstrated in three dogs with no to moderate PH, and could not be demonstrated in five dogs with severe PH. In two dogs thoracic radiographs showed only mild interstitial changes, while computer tomography and postmortem examination revealed severe pulmonary interstitial and vascular disease. These results suggest that dogs may open IPAVAs and that opening of such anastomoses may play a regulatory role in the development of PH. There may be a marked discrepancy between radiographic changes and disease severity in A. vasorum. Copyright © 2015 Elsevier B.V. All rights reserved.

    The aim was to examine duration of illness and body mass index as possible moderators of the relationship between eating disorder severity and functional impairment, as well as psychological distress as a possible mediator of this relationship. The study included 159 patients diagnosed with bulimia nervosa, binge eating disorder or eating disorder not otherwise specified. Regression analysis was applied to assess the effect of the hypothesized moderators and mediators. Eating disorder severity was measured with the Eating Disorder Examination Questionnaire, functional impairment was measured with the Sheehan Disability Scale, and psychological distress was measured with the Symptom Check List-90-R. Duration of illness and body mass index were assessed clinically. Duration of illness significantly moderated the relationship between eating disorder severity and functional impairment; the relationship was strongest for patients with a shorter duration of illness. Psychological distress partly mediated the relationship between eating disorder severity and functional impairment. Duration of illness significantly moderated the relationship between psychological distress and functional impairment; the strongest relationship was seen for patients with a shorter duration of illness. Body mass index was not a significant moderator of the relationship between ED severity and functional impairment. Overall, this study established a link between ED severity, psychological distress and functional impairment indicating that both eating disorder severity and psychological distress are more strongly related to impaired role functioning for patients with more recent onset of an eating disorder. More research in the complex relationship between ED severity and functional impairment is needed.

  1. Studying Different Clinical Syndromes Of Paediatric Severe Malaria Using Plasma Proteomics

    Background- Severe Plasmodium falciparum malaria remains one of the major causes of childhood morbidity and mortality in Africa. Severe malaria manifests itself as three main clinical syndromes-impaired consciousness (cerebral malaria), respiratory distress and severe malarial anaemia. Cerebral malaria and respiratory distress are major contributors to malaria mortality but their pathophysiology remains unclear. Motivation/Objectives- Most children with severe malaria die within the first 24 hours of admission to a hospital because of their pathophysiological conditions. Thus, along with anti-malarial drugs, various adjuvant therapies such as fluid bolus (for hypovolaemia) and anticonvulsants (for seizures) are given to alleviate the sick child’s condition. But these therapies can sometimes have adverse effects. Hence, a clear understanding of severe malaria pathophysiology is essential for making an informed decision regarding adjuvant therapies. Methodology- We used mass spectrometry-based shotgun proteomics to study plasma samples from Gambian children with severe malaria. We compared the proteomic profiles of different severe malaria syndromes and generated hypotheses regarding the underlying disease mechanisms. Results/Conclusions- The main challenges of studying the severe malaria syndromes using proteomics were the high complexity and variability among the samples. We hypothesized that hepatic injury and nitric oxide play roles in the pathophysiology of cerebral malaria and respiratory distress.

    The effectiveness of bronchial thermoplasty (BT) has been reported in patients with severe asthma, yet its effect on different bronchial structures remains unknown. We sought to examine the effect of BT on bronchial structures and to explore the association with clinical outcome in patients with severe refractory asthma. Bronchial biopsy specimens (n = 300) were collected from 15 patients with severe uncontrolled asthma before and 3 months after BT. Immunostained sections were assessed for airway smooth muscle (ASM) area, subepithelial basement membrane thickness, nerve fibers, and epithelial neuroendocrine cells. Histopathologic findings were correlated with clinical parameters. BT significantly improved asthma control and quality of life at both 3 and 12 months and decreased the numbers of severe exacerbations and the dose of oral corticosteroids. At 3 months, this clinical benefit was accompanied by a reduction in ASM area (median values before and after BT, respectively: 19.7% [25th-75th interquartile range (IQR), 15.9% to 22.4%] and 5.3% [25th-75th IQR], 3.5% to 10.1%, P bronchial reactivity, particularly ASM, neuroendocrine epithelial cells, and bronchial nerve endings.

    Full Text Available Objective: To investigate the application of percutaneous endoscopic gastrostomy (PEG to patients with severe craniocerebral injury for the purpose of nutritional support therapy and pulmonary infection prevention. Methods: A total of 43 patients with severe craniocerebral injury admitted to our department from January 2008 to December 2012 received PEG followed by nutritional therapy. There were other 82 patients who were prescribed nasal-feeding nutrition. Nutrition status was evaluated by comparing serum albumin levels, and the incidence of pulmonary infection 1 week before and 2 weeks after operation was identifi ed and compared. Results: Both PEG and nasal-feeding nutrition therapies have significantly levated serum albumin levels (P<0.05. Serum albumin levels before and after nutritional therapies showed no significant difference between the two groups (P>0.05. The incidence of pulmonary infection in PEG group was significantly decreased compared with that in nasal-feeding nutrition group (P<0.05. Conclusion: PEG is an effective method for severe craniocerebral injury patients. It can not only provide enteral nutrition but also prevent pulmonary infection induced by esophageal refl ux.

    Full Text Available Pranabashis Haldar Respiratory Biomedical Research Unit, Glenfield Hospital, University of Leicester, Leicester, UK Abstract: Mepolizumab (Nucala® is an effective and specific anti-eosinophil molecular therapy that has recently been approved as add-on therapy for the management of severe eosinophilic asthma by the US Food and Drug Administration (FDA, European Medicines Agency (EMA; European Union and more recently National Institute for Health and Care Excellence (NICE; UK. It is one of several molecular therapies in development for this indication and is illustrative of the strategic trajectory for pharmaceutical drug development taken over the past decade in several disease areas. Molecular therapies offer the prospect of improved specificity and effectiveness of biological effect. However, this necessitates a clear understanding of the underlying mechanistic pathways underpinning pathological processes, to inform drug development that yields novel more efficacious treatment options with a better clinical profile than existing agents. For the first time, utilization of molecular therapies in clinical trials is providing a novel in vivo model to characterize the association between specific pathways and clinical disease expression. It is increasingly recognized that asthma exhibits both clinical and pathological heterogeneity. It follows that a one-size-fits-all approach will not be appropriate and cost-effectiveness may only be achieved by identifying responder subgroups. This so-called personalized approach to therapy is being supported by the parallel development of companion biomarkers for clinical application. In this review, the author summarizes the clinical studies, their interpretation and the lessons learnt with mepolizumab that have informed our understanding of the approach to personalized molecular therapy in asthma.

    We examined the validity and utility of the DSM-5 severity ratings for anorexia nervosa (AN) in a clinical (treatment-seeking) sample (N = 273; 95.6% women). Participants classified with mild, moderate, severe, and extreme severity of AN based on their measured body mass index, differed significantly from each other in eating disorder features, putative maintenance factors, and illness-specific functional impairment (medium effect sizes). However, they were statistically indistinguishable in psychiatric-disorder comorbidity and distress, demographics, and age-of-AN onset. The implications of our findings, providing limited support for the DSM-5 severity ratings for AN, and directions for future research are outlined. Copyright © 2018 Elsevier B.V.

    Background Elevation of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) is prominent in acute dengue illness. The World Health Organization (WHO) 2009 dengue guidelines defined AST or ALT≥1000 units/liter (U/L) as a criterion for severe dengue. We aimed to assess the clinical relevance and discriminatory value of AST or ALT for dengue hemorrhagic fever (DHF) and severe dengue. Methodology/Principal Findings We retrospectively studied and classified polymerase chain reaction positive dengue patients from 2006 to 2008 treated at Tan Tock Seng Hospital, Singapore according to WHO 1997 and 2009 criteria for dengue severity. Of 690 dengue patients, 31% had DHF and 24% severe dengue. Elevated AST and ALT occurred in 86% and 46%, respectively. Seven had AST or ALT≥1000 U/L. None had acute liver failure but one patient died. Median AST and ALT values were significantly higher with increasing dengue severity by both WHO 1997 and 2009 criteria. However, they were poorly discriminatory between non-severe and severe dengue (e.g., AST area under the receiver operating characteristic [ROC] curve = 0.62; 95% confidence interval [CI]: 0.57–0.67) and between dengue fever (DF) and DHF (AST area under the ROC curve = 0.56; 95% CI: 0.52–0.61). There was significant overlap in AST and ALT values among patients with dengue with or without warning signs and severe dengue, and between those with DF and DHF. Conclusions Although aminotransferase levels increased in conjunction with dengue severity, AST or ALT values did not discriminate between DF and DHF or non-severe and severe dengue. PMID:22679523

    The purpose of this review is to summarize the most important human clinical trials of antioxidants as cancer prevention agents conducted to date, provide an overview of currently ongoing studies, and discuss future steps needed to advance research in this field. To date there have been several large (at least 7000 participants) trials testing the efficacy of antioxidant supplements in preventing cancer. The specific agents (diet-derived direct antioxidants and essential components of antioxidant enzymes) tested in those trials included β-carotene, vitamin E, vitamin C, selenium, retinol, zinc, riboflavin, and molybdenum. None of the completed trials produced convincing evidence to justify the use of traditional antioxidant-related vitamins or minerals for cancer prevention. Our search of ongoing trials identified six projects at various stages of completion. Five of those six trials use selenium as the intervention of interest delivered either alone or in combination with other agents. The lack of success to date can be explained by a variety of factors that need to be considered in the next generation research. These factors include lack of good biological rationale for selecting specific agents of interest; limited number of agents tested to date; use of pharmacological, rather than dietary, doses; and insufficient duration of intervention and follow-up. The latter consideration underscores the need for alternative endpoints that are associated with increased risk of neoplasia (i.e., biomarkers of risk), but are detectable prior to tumor occurrence. Although dietary antioxidants are a large and diverse group of compounds, only a small proportion of candidate agents have been tested. In summary, the strategy of focusing on large high-budget studies using cancer incidence as the endpoint and testing a relatively limited number of antioxidant agents has been largely unsuccessful. This lack of success in previous trials should not preclude us from seeking novel

The common age for boys to have OSD is between 12 and 15 years and for girls, between 8 and 12 years. Radiographic studies are helpful in diagnosis and treatment of OSD.Purpose: We examine the age at onset of OSD in detail and investigate the relationship between clinical findings, radiographic bone morphology, and the severity of OSD in adolescents.Results: The average age at onset of knee pain was 12 years and 6 months – 12 years and 9 months in boys, and 12 years and 1 month in girls. Boys were significantly older than girls at onset. In addition, there were significant relationships between duration from first onset to visit to the clinic, radiographic bone stage, body morphology, and radiographic severity. The patients who delayed their visit to the clinic from the first onset of pain and who were older showed a later bone stage and more radiographic severity grade of OSD. There was significant differences concerning weight and body mass index between severity grade I and III. Conclusion: For the age at the onset of OSD, the mean age of boys was significantly older than that of girls. The patients at a later bony stage had a higher severity grade. The boys and girls with OSD who had less weight or body mass index showed less severity.Keywords: Osgood–Schlatter disease, radiographic classification, tibial tuberosity, body morphology

    In patients with severe preeclampsia there is an increased risk of postpartum hemorrhage, but the hemodynamic changes associated with severe preeclampsia make the management of any kind of bleeding particularly troublesome. There are many pharmacological options for the management of postpartum hemorrhage, oxytocin being the first line of treatment. There is as yet no evidence about the safety and efficacy of using carbetocin, an oxytocin agonist, in these patients. We aimed to compare oxytocin with carbetocin for the routine prevention of postpartum hemorrhage in patients with severe preeclampsia. We performed a prospective double-blind randomized controlled trial in 60 women with severe preeclampsia, recruited between July and September 2010. The women were randomized to receive either oxytocin or carbetocin during the third stage of labour. The primary outcome measure was postpartum hemorrhage requiring additional uterotonics, and the secondary outcome measures were the difference in hemoglobin levels between groups, the development of oliguria, and hemodynamic status (mean arterial pressure and heart rate) after administration of the drug. Carbetocin was as effective as oxytocin in the prevention of postpartum hemorrhage in women with severe preeclampsia. Carbetocin had a safety profile similar to that of oxytocin, and it was not associated with the development of oliguria or hypertension in this cohort. Carbetocin is an appropriate alternative to oxytocin for the prevention of postpartum hemorrhage in women with severe preeclampsia. Considering that it appears not to have a major hemodynamic effect in women with severe preeclampsia and that it uses a lower volume per dose than oxytocin, it should be considered a valid option in the management of the third stage of labour in women with hypertensive disorders of pregnancy.

  13. [Good practice is a means for preventing fraud in clinical research].

    The aim of this article is to present the findings concerning scientific fraud that have appeared in case reports. Deliberate scientific fraud does exist. The fact that most of the documented cases have occurred in Anglo-Saxon countries seems to indicate, not that Anglo-Saxons are more prone to scientific fraud, but rather that they have been more successful in bringing it to light. Since 1974, 72 cases have been reported in which there was either conclusive evidence or else a strong presumption of fraud: one case in Switzerland, one in Canada, four in Australia, 14 in Great Britain and 52 in the United States. Fraud is estimated to affect 2-5% of clinical research trials. Referees and readers do not set out to track fraud. The American Commission has proposed the terms "misappropriation, interference, misrepresentation" to define fraud. Voluntary fraud is hidden and its detection delayed. In well-known cases, more than 5 years elapsed before the information reached the scientific community. Whistle blowers must sustain a determined effort to denounce fraud over a period of 1-3 years if they are to trigger an investigation. Some whistle blowers have themselves been accused of fraud because their claims proved so embarrassing. Fraud can lead to severe accidents and generate expenditure that those responsible, or the institutions they work for, will never pay back. Frauders are usually motivated by the desire for material gain or the desire to become well-known. The motivating factor may be personal enrichment, or a need for funds for a not-for-profit association. People found guilt of fraud always have good excuses. Some simply do not realize what they have done. A knowledge of research methodology and critical appraisal methods can help to prevent fraud. Good clinical, laboratory and manufacturing practice can help to prevent misconduct and trickery. Audits and inspections are another essential means of combatting fraud.

    Evaluate psychometric properties of the Pediatric Insomnia Severity Index (PISI), a brief measure of insomnia severity. Clinically referred youth ( n = 462; 283 males, 179 females, mean age = 7.28 ± 2.05 years) and their caregiver(s) completed sleep evaluation including the PISI, Children's Sleep Habits Questionnaire, and sleep disorders inventory for students. Tests of reliability and validity and confirmatory factor analysis (CFA) were conducted to assess PISI psychometric properties. Exploratory analyses were conducted to examine insomnia severity by insomnia diagnosis. Measures of internal consistency for the PISI factor scores varied. CFA indicated that a two-factor model had optimal fit relative to a single-factor solution. Overall, convergent and discriminant validity of PISI factors were supported. Insomnia severity varied by diagnosis. Findings provide preliminary support for the reliability and validity of the PISI within a large pediatric sample and for its clinical utility as a brief measure of insomnia severity. © The Author 2016.

    Severe fever with thrombocytopenia syndrome (SFTS) associated with severe fever with thrombocytopenia syndrome virus (SFTSV) is an emerging infectious disease. 12 patients with severe fever with thrombocytopenia syndrome in our study were presented mainly with fever and severe malaise. The clinical manifestations typically became worse on the 6th or 7th day. The average fever time is 9.11 ± 1.54 days. Most of them had multiorgan dysfunction, and part of them had hemophagocytic lymphohistiocytosis histiocytosis (HLH). The characteristic laboratory findings in the early stage were the drop of white blood cells (WBC), platelets (PLT) and serum Ca++, while increase of aspartate amino transferase (AST), creatine kinase (CK), and lactate dehydrogenase (LDH). CD3+CD4+ were significantly decreased, while CD3-CD56+ were significantly increased, whereas CD3+CD8+ were constantly elevated throughout the disease course. Ten to 14 days after illness onset, symptoms were improved, accompanied by resolution of laboratory abnormalities. These results indicate that severe fever with thrombocytopenia syndrome has an acute onset and self-limited course. It is a systemic infection. The host immune response caused tissues and organs injury. The improvement of symptoms and laboratory tests is consistent with the elimination of the virus and recover of immune response. Further investigation should be done in order to better understand this disease and guide the clinical treatment. Copyright © 2013 Elsevier Editora Ltda. All rights reserved.

    2011-01-01

    Full Text Available Purpose: Mutations of the a-1 subunit sodium channel gene (SCN1A cause severe myoclonic epilepsy of infancy (SMEI. To date, over 300 mutations related to SMEI have been described. In the present study, we report new SCN1A mutations and the clinical features of SMEI cases. Materials and Methods: We studied the clinical and genetic features of nine patients diagnosed with SMEI at the Pediatric Neurology Department of Istanbul Medical Faculty. Results: Five patients had nonsense mutations, two had missense mutations, one had a splice site mutation and one had a deletion mutation of the SCN1A gene. Mutations at c.3705+5G splice site, p.trip153X nonsense mutation and deletion at c.2416_2946 have not been previously described. The seizures started following whole cell pertussis vaccination in all patients. The seizures ceased in one patient and continued in the other eight patients. Developmental regression was severe in three patients, with frequent status epilepticus. The type of mutation was not predictive for the severity of the disease. Two of the three patients with severe regression had nonsense and missense mutations. Conclusions : Dravet syndrome can be result of several different types of mutation in SCN1A gene. Onset of the seizures after pertussis vaccination is an important clue for the diagnosis and neuro- developmental delay should be expected in all patients.

    We studied the prevalence of severe crouch gait over a 15-year period in a defined population of children with spastic diplegia and Gross Motor Function Classification System levels II and III, to determine if there had been a decrease following changes to the management of equinus gait. These changes were replacing observational with three-dimensional gait analysis, replacing single level with multilevel surgery, and replacing gastrocsoleus lengthening with gastrocnemius recession. Of 464 children and adolescents with spastic diplegia who underwent three-dimensional gait analysis, 27 had severe crouch gait. Seventeen of these had been managed by isolated lengthening of the gastrocsoleus. Following changes in the management of equinus gait, the prevalence of severe crouch gait decreased from 25% and stabilised at a significantly lower rate, fluctuating between 0% and 4% annually (p spastic diplegia.

    On the basis of a series of 18 cases of severe eclampsia, the authors analyse the predisposing circumstances for these episodes and the method of delivery. Caesarian section is still the usual method of delivery in severe cases (12/18). There is a high perinatal mortality (4/18), which is principally due to foetal distress which is inevitable during the episodes, to hypotrophy which is present in 3 out of 4 cases and to prematurity. There were no maternal deaths in this particular series. In the second part of the article, the authors consider the management and treatment of the eclamptic episode itself: relieve the maternal and foetal anoxia, stabilize the blood pressure, correct the hypovolaemia and prevent the development of convulsions.

    Biliary lithiasis in patients with severe preeclampsia has not been well studied. To describe the frequency and clinical course of biliary lithiasis in patients with severe preeclampsia. Cross-sectional study on 141 women with severe preeclampsia who had an abdominal ultrasound performed during the pre-partum period or in the immediate puerperium. Patients were treated in the Intensive Care Unit of the Hospital de Ginecologia y Obstetricia núm. 3, Centro Medico Nacional La Raza, IMSS (Mexico), in the period of November 26, 2006 to June 26, 2009. Findings from gallbladder lithiasis (sand, solitary stone, multiple stones or wall calcification) and choledocho conduit were reported. Significant maternal data (clinical and laboratory) and perinatal results of patients without stones (group A) were compared to patients (group B) with stones. Measures of central tendency and dispersion, and T-test were used. Frequency of gallbladder lithiasis was 15% (21 cases). Solitary stone were found in 12 cases, multiple stones in seven cases and gallbladder calcification in two cases. There were no cases of choledocholithiasis. Epigastric pain was present in 13 cases (9.2%: group A, 10 cases [7.1%] vs. group B, 3 cases [2.1%], p = 0.06). There were no complications in patients with lithiasis and none required invasive procedures. Clinical evolution and perinatal results were similar in both groups. Duration of stay in the intensive care unit was similar (group A, 2.2 +/- 0.18 days vs. group B, 2.1 +/- 0.13 days, p = 0.86). The frequency of biliary lithiasis in patients with severe preeclampsia was 15%. There were no adverse effects on the maternal clinical course or on the perinatal results.

    To summarize the clinical characteristics of whooping cough in children and analyze the risk factors for severe whooping cough. A retrospective analysis was made on the clinical data of 247 children with whooping cough in Children's Hospital of Chongqing Medical University between Jan 2013 and Dec 2014. Of these patients, 126 were male, 121 were female, the median age was 3.1 months (23 days-4 years and eight months old). The patients were divided into two groups, group 1 had infants less than 3 months of age (n=120) and group 2 had infants and young children older than 3 months (n=127) according to their age. On the other hand, the patients were also divided into two groups according to vaccination status: vaccinated group (received diphtheria toxoid, tetanus toxoid, and acellular pertussis, DTP) (n=31) and unvaccinated group (n=188). Pure Bordetella pertussis infection was seen in 106 cases, and 141 cases had mixed infection. Severe disease was seen in 13 cases, and the other 234 cases had the modest disease. Clinical data were retrospectively analyzed and compared. (1) Bordetella pertussis was identified in 57/680 cases (8.4%) in 2013, and 190/1 856 cases (10.2%) in 2014. The disease could be seen throughout the year, but 182 cases (73.7%) occurred in summer or autumn; 202 cases (81.8%) were less than 6 months. (2) Paroxysmal cough was seen in 238 cases (96.4%) , 61 cases (24.7%) had inspiratory whoop. Infants in group 1 often had episodes of cyanosis, apnea and suffocation (χ² = 19.999, 12.081, 6.508, Pfall. Infants less than 3 months old, unvaccinated with DTP had high susceptibility to pertussis, often had a severe clinical presentation and severe complications, had a high mortality rate.

  1. Circulating Microvesicles Are Elevated Acutely following Major Burns Injury and Associated with Clinical Severity.

    Directory of Open Access Journals (Sweden)

    Kieran P O'Dea

    Full Text Available Microvesicles are cell-derived signaling particles emerging as important mediators and biomarkers of systemic inflammation, but their production in severe burn injury patients has not been described. In this pilot investigation, we measured circulating microvesicle levels following severe burns, with severe sepsis patients as a comparator group. We hypothesized that levels of circulating vascular cell-derived microvesicles are elevated acutely following burns injury, mirroring clinical severity due to the early onset and prevalence of systemic inflammatory response syndrome (SIRS in these patients. Blood samples were obtained from patients with moderate to severe thermal injury burns, with severe sepsis, and from healthy volunteers. Circulating microvesicles derived from total leukocytes, granulocytes, monocytes, and endothelial cells were quantified in plasma by flow cytometry. All circulating microvesicle subpopulations were elevated in burns patients on day of admission (day 0 compared to healthy volunteers (leukocyte-microvesicles: 3.5-fold, p = 0.005; granulocyte-microvesicles: 12.8-fold, p<0.0001; monocyte-microvesicles: 20.4-fold, p<0.0001; endothelial- microvesicles: 9.6-fold, p = 0.01, but decreased significantly by day 2. Microvesicle levels were increased with severe sepsis, but less consistently between patients. Leukocyte- and granulocyte-derived microvesicles on day 0 correlated with clinical assessment scores and were higher in burns ICU non-survivors compared to survivors (leukocyte MVs 4.6 fold, p = 0.002; granulocyte MVs 4.8 fold, p = 0.003. Mortality prediction analysis of area under receiver operating characteristic curve was 0.92 (p = 0.01 for total leukocyte microvesicles and 0.85 (p = 0.04 for granulocyte microvesicles. These findings demonstrate, for the first time, acute increases in circulating microvesicles following burns injury in patients and point to their potential role in propagation of sterile SIRS

    Fat embolism syndrome (FES) is rare and diagnosis is challenging. Clinical manifestations are non-specific and no biochemical tests are reliable for diagnosis, highlighting the importance of thoracic CT. Our goal was to describe the CT manifestations of FES and assess whether imaging findings, time of onset of symptoms and time of surgery correlate with clinical course and severity of the disease. Retrospective review of 49 patients with respiratory distress after trauma/intramedullary nail fixation over a 10 year period; 12 patients met clinical criteria and were categorized as non-fulminant (NF-FES) or fulminant FES (F-FES). CT images were analyzed and electronic records reviewed for clinical findings, timeline from trauma to surgery and onset of symptoms. Pearson Chi-square and Levene's test were used and results considered significant when p75%) whereas most NF-FES had limited involvement (p<0.01). Centrilobular nodules were the predominant finding in 3/12 (16%). Median time between fracture and onset of symptoms was 43h, in 9/12 patients manifesting after surgery. Mean time between trauma and surgery was 20h in NF-FES and 52h in F-FES (p=0.02). The most common CT features of FES were ground-glass opacity and consolidation, less commonly, centrilobular nodules. The extent of ground-glass opacities and the presence of consolidation correlated with disease severity. Significant difference was found from time of trauma to surgery in the two groups however is uncertain whether delayed surgery truly increased the risk of F-FES.

    A new case of severe clinical phenotype of the cat-eye syndrome: We report on a female infant with severe clinical phenotype of Cat-Eye Syndrome (CES). At birth, she had respiratory distress and marked hypotonia. Physical examination showed major craniofacial anomalies including microcephaly, bilateral total absence of the external ears, hypertelorism, bilateral ocular coloboma of iris and micrognathia. In addition, she had anal stenosis, a patent ductus arteriosus and intra- and extra- hepatic biliary atresia. She deteriorated with the development of bradycardia. She died at age one month of cardiac failure. Cytogenetic analysis of the proband showed an extra de novo small bisatelllited marker chromosome in all cells examined. Molecular cytogenetic analysis with fluorescence in situ hybridization (FISH) identified the marker as a CES chromosome. Thus, the patient's karyotype was: 47, XX, +idic(22)(pter-->q11.2 ::q11.2-->pter). The duplication breakpoints giving rise to the CES chromosome were distal to the DiGeorge Syndrome (DGS) locus 22q11.2. The marker could be classed as a type 11 symmetrical (10). According to a recent review of CES literature (1) only 41 % of the CES patients have the combination of iris coloboma, anal anomalies and preauricular anomalies. Almost 60% are hard to recognize by their phenotype alone. Only twelve patients showed a severe clinical phenotype leading to the death of the child. This phenotypic variability increases the difficulties of genetic counseling.

    Leber congenital amaurosis (LCA) and early-onset severe retinal dystrophy (EOSRD) are both genetically and phenotypically heterogeneous, and characterised clinically by severe congenital/early infancy visual loss, nystagmus, amaurotic pupils and markedly reduced/absent full-field electroretinograms. The vast genetic heterogeneity of inherited retinal disease has been established over the last 10 - 20 years, with disease-causing variants identified in 25 genes to date associated with LCA/EOSRD, accounting for 70-80% of cases, with thereby more genes yet to be identified. There is now far greater understanding of the structural and functional associations seen in the various LCA/EOSRD genotypes. Subsequent development/characterisation of LCA/EOSRD animal models has shed light on the underlying pathogenesis and allowed the demonstration of successful rescue with gene replacement therapy and pharmacological intervention in multiple models. These advancements have culminated in more than 12 completed, ongoing and anticipated phase I/II and phase III gene therapy and pharmacological human clinical trials. This review describes the clinical and genetic characteristics of LCA/EOSRD and the differential diagnoses to be considered. We discuss in further detail the diagnostic clinical features, pathophysiology, animal models and human treatment studies and trials, in the more common genetic subtypes and/or those closest to intervention. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Sleep disruption is common among hematopoietic cell transplant (HCT) recipients, with over 50% of patients experiencing sleep disruption pre-transplant, up to 82% experiencing moderate to severe sleep disruption during hospitalization for transplant, and up to 43% in the post-transplant period. These rates of sleep disruption are substantially higher than the general population. Although sleep disruption can be distressing to patients and contribute to diminished quality of life, it is rarely discussed during clinical visits. The goal of the current review is to draw attention to sleep disruption as a clinical problem in HCT in order to facilitate patient education, intervention, and research. The review opens with a discussion of sleep disruption measurement and clinical diagnosis of sleep disorders. An overview of the prevalence, severity, and chronicity of sleep disruption and disorders in patients receiving HCT follows. Current evidence regarding sociodemographic and clinical predictors of sleep disruption and disorders is summarized. The review concludes with suggestions for behavioral and pharmacologic management of sleep disruption and disorders as well as directions for future research. PMID:24747335

    As a part of the evaluation of accident management strategies for severe accident prevention or mitigation in a station blackout scenario for YGN 3 and 4, an external vessel cooling strategy for the prevention of reactor vessel failure has been estimated using the MAAP4 computer code. The sensitivity studies have been performed such as actuating timings and the number of spray pumps used. To explore external vessel cooling strategies, containment spray pumps were actuated by varying time spanning core uncovery, core melting and relocation of molten core material. It was shown that flooding of the reactor cavity using the containment spray system may prevent reactor vessel failure but may not prevent the failure of the relocation of molten core material during the station blackout sequence of YGN 3 and 4. Reactor vessel failure can be prevented by external vessel cooling using condensed water from the operation of two containment spray pumps at the time of core melting and using water from the operation of one containment spray pumps at the time of core melting and using water from the operation of one containment spray pump at the time of core uncovery.

    Tungiasis (sand flea disease) is a neglected tropical disease. Heavy infestation results in mutilation of the feet and difficulty in walking. We identified eight individuals with extremely severe tungiasis in rural Madagascar. To prevent reinfestation, four individuals received solid shoes and four received a daily application of an herbal repellent effective against Tunga penetrans. Over a period of 10 weeks the feet were examined and the severity of tungiasis-associated morbidity was measured. Within this period, the severity score for acute tungiasis decreased 41% in the shoe group and 89% in the repellent group. The four major inflammation-related symptoms disappeared in the four patients of the repellent group, but only in two patients of the shoe group. Those observations indicate that cases with extremely severe tungiasis, associated morbidity almost totally disappears within 10 weeks if the feet are protected by a repellent. Wearing shoes reduced acute morbidity only marginally.

  8. Design measures for prevention and mitigation of severe accidents at advanced water cooled reactors. Proceedings of a technical committee meeting

    International Nuclear Information System (INIS)

    1998-06-01

    Over 8500 reactor-years of operating experience have been accumulated with the current nuclear energy systems. New generations of nuclear power plants are being developed, building upon this background of experience. During the last decade, requirements for equipment specifically intended to minimize releases of radioactive material to the environment in the event of a core melt accident have been introduced, and designs for new plants include measures for preventing and mitigating a range of severe accident scenarios. The IAEA Technical Committee Meeting on Impact of Severe Accidents on Plant Design and Layout of Advanced Water Cooled Reactors was jointly organized by the Department of Nuclear Energy and the Department of Nuclear Safety to review measures which are being incorporated into advanced water cooled reactor designs for preventing and mitigating severe accidents, the status of experimental and analytical investigations of severe accident phenomena and challenges which support design decisions and accident management procedures, and to understand the impact of explicitly addressing severe accidents on the cost of nuclear power plants. This publication is intended to provide an objective source of information on this topic. It includes 14 papers presented at the Technical Committee meeting held in Vienna between 21-25 October 1996. It also includes a Summary and Findings of the Working Groups. The papers were grouped in three sections. A separate abstract was prepared for each paper

    To assess the efficacy of a preemptive antifungal therapy in preventing proven candidiasis in critically ill surgical patients. Before/after intervention study, with 2-yr prospective and 2-yr historical control cohorts. Surgical intensive care unit (SICU) in a university-affiliated hospital. Nine hundred and thirty-three patients, 478 in the prospective group and 455 in the control group, with SICU stay > or =5 days. During the prospective period, systematic mycological screening was performed on all patients admitted to the SICU, immediately at admittance and then weekly until discharge. A corrected colonization index was used to assess intensity of Candida mucosal colonization. Patients with corrected colonization index > or =0.4 received early preemptive antifungal therapy (fluconazole intravenously: loading dose 800 mg, then 400 mg/day for 2 wks). End points of this study were the frequency of proven candidiasis, especially SICU-acquired candidiasis. During the retrospective period, 32 patients of 455 (7%) presented with proven candidiasis: 22 (4.8%) were imported and 10 (2.2%) were SICU-acquired cases. During the prospective period, 96 patients with corrected colonization index > or =0.4 of 478 received preemptive antifungal treatment and only 18 cases (3.8%) of proven candidiasis were diagnosed; all were imported infections. Candida infections occurred more frequently in the control cohort (7% vs. 3.8%; p = .03). Incidence of SICU-acquired proven candidiasis significantly decreased from 2.2% to 0% (p test). Incidence of proven imported candidiasis remained unchanged (4.8% vs. 3.8%; p = .42). No emergence of azole-resistant Candida species (especially Candida glabrata, Candida krusei) was noted during the prospective period. Targeted preemptive strategy may efficiently prevent acquisition of proven candidiasis in SICU patients. Further studies are being performed to assess cost-effectiveness of this strategy and its impact on selection of azole

    Body Dysmorphic Disorder is a putative obsessive-compulsive spectrum disorder. This exploratory study systematically examined prevalence and clinical correlates of Body Dysmorphic Disorder (BDD) comorbidity in an inpatient Obsessive-Compulsive Disorder (OCD) population. Consecutive patients from an OCD Intensive Residential Treatment program were included (N = 275). Clinician-rated and patient-rated measures were administered at baseline and repeated at discharge. The prevalence of BDD was determined and clinical characteristics were statistically compared between groups with (N = 42) and without (N = 233) comorbid BDD. The prevalence of BDD among residential patients with OCD was 15.3% (N = 42). Those with comorbid BDD were younger (p = 0.007) and more predominantly female (p = 0.02), with lower marriage rates (p = 0.006), more severe depression (p = 0.003) and increased self-reported illicit substance use histories (p = 0.003) versus those without BDD. This cohort also had earlier onset OCD (p = 0.02) and more severe hoarding (p = 0.01), symmetry (p = 0.01), reassurance-seeking (p = 0.01) and checking symptoms (p = 0.01) than patients without comorbid BDD. OCD treatment response was unaffected by the presence of BDD. BDD is a common comorbidity in severe OCD. Younger women and those with early-onset OCD appear more likely to have BDD. OCD patients with BDD also have increased hoarding, symmetry, reassurance-seeking and checking severity, which requires consideration in treatment planning.

    Rosacea is a common chronic inflammatory disorder affecting facial skin. Currently, no accurate and objective method is available for assessing the severity of rosacea. Most studies use the National Rosacea Society Standard (NRSS) grading method, which lacks objectivity and yields varying results. Eighteen patients with rosacea were included. Clinical severity was assessed on the basis of the NRSS grade, Investigators' Global Assessment, Patients' Global Assessment, and Dermatology Quality of Life Index. A skin color analysis system was used to measure the facial area showing erythema, and biophysical parameters of facial skin (transepidermal water loss and skin surface hydration) were examined. To find statistical significant in classification severity of the rosacea, statistical analysis was performed with all parameters. A significant correlation (P rosacea of different levels of severity (mild, moderate, severe; P rosacea, in addition to biophysical parameter assessment. The combination of these two analytical methods enabled objective and quantitative evaluation of the severity of rosacea. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Acne vulgaris is known to impair many aspects of quality of life. However, the correlation of this impairment with clinical severity remains equivocal despite various school, community and hospital-based studies. A hospital-based study was undertaken to measure the impairment of quality of life of patients of acne vulgaris and correlate it with the severity of lesions. This was a cross-sectional, questionnaire-based study in a cohort of 100 patients of acne vulgaris attending the outpatient department of our referral hospital. A physician measured the severity of lesions using the global acne grading system, and patients assessed quality of life by completing a questionnaire (Cardiff acne disability index). A correlation of these two was done; some additional correlations were brought out through demographic data collected from the patients. There was no correlation between the severity of acne vulgaris and an impaired quality of life. Patients who consumed alcohol and/or smoked cigarettes were found to have an impaired quality of life. While the severity of acne progressively lessened in older patients, the impact on quality of life increased. The sample size was small and there was a lack of guaranteed reliability on the self-reported quality of life. The severity of acne vulgaris does not correlate with impairment in quality of life.

    Cornelia de Lange syndrome (CdLS) is a rare multisystem disorder in which hearing loss (HL) has been reported. However, no data are available concerning the association between audiological findings, clinical severity score and genotype. The study involved 44 pediatric patients aged 1-18 years with a confirmed diagnosis of CdLS, all of whom underwent a full otolaryngological and audiological examination. The presence of NIPBL and SMC1 mutations was also evaluated. According to the severity of clinical phenotypes, 12 (27.3%) children were mild, 15 (34.1%) were moderate and 17 (38.6%) were severe. Thirty-eight children (86%) had OME. Eight children had normal hearing, including one (12.5%) with a severe phenotype. Bilateral sensorineural hearing loss (SNHL) was diagnosed in 10 children (22.7%): the degree of HL was severe in 8 (80%), all with a severe phenotype. Conductive hearing loss (CHL) was present in 26 patients (59.1%), of whom 8 (30.8%) had a severe phenotype. A severe phenotype was more prevalent among the patients with moderate to severe HL (10/16, 62.5%) than among those with slight/mild HL or normal hearing (7/28, 25.0% p=0.013). NIPBL mutations were detected in 22 patients (50%): 13 (59.1%) with truncating mutations, four (18.2%) with missense mutations, and five (22.7%) with splicing mutations. The frequency of NIPBL truncating mutations was similar in the children with SNHL and those with CHL, whereas this kind of mutation was not found in children with normal hearing. Together with SNHL, CHL is an important cause of HL in children with CdLS, and can be associated with a severe phenotype. Moreover, CHL can be associated with NIPBL mutations, particularly truncating mutations. These results highlight the importance of the early identification of audiological problems in children with CdLS and their precise genetic characterization. Copyright © 2014 Elsevier Ireland Ltd.

    Full Text Available Objective: to reveal the basic regularities in the development of lipid metabolic disturbances in severe sepsis and to evaluate the efficiency of parenteral use of new balanced lipid emulsions in this cohort of patients. Subjects and methods. A prospective study was conducted in 88 patients with severe sepsis of different etiologies in the intensive care unit (ICI, Sverdlovsk Regional Clinical Hospital One. Among the lipid metabolic parameters, serum cholesterol, triglycerides (TG, high-density lipoproteins, low-density lipoproteins, and atherogenicity index were measured. Out of the systemic inflammatory markers and the additional criteria for sepsis severity, the serum levels of C-reactive protein, nitric oxide, lactate, D-dimers, the anti-inflammatory cytokine IL-4 and the proinflammatory cytokine IL-8 were determined. Serum was taken on days 1, 3, 5, and 7 after admission to the ICI. The quantitative attributes were comparatively analyzed by the statistical program «Statistica 6.0». Results. The severity assessed by the APACHE II scale, the degree of multiple organ failures (MOF evaluated by the SOFA scale, and lung lesion according to the MURREY scale were found to be closely related to the baseline serum TG levels in patients with severe sepsis. The findings suggest that patients with high TG levels have much higher resuscitative mortality rates. The clinical evaluation of the efficiency of the new method for correction of lipid metabolic disturbances in severe sepsis has indicated that the patients receiving balanced (omega-3 fatty acids-enriched fat emulsions as 20% Lipoplus solution had lower APACHE II scores within the first 7 days of intensive therapy and significantly more positive SOFA MOF changes. Specific changes were revealed in the presence of systemic inflammatory markers, such as C-reactive protein, IL-8, and IL-4, which confirms that balanced lipid emulsions are able to affect the system of pro- and anti

    Zoonotic cutaneous leishmaniasis caused by Leishmania (L.) major parasites affects urban and suburban areas in the center and south of Tunisia where the disease is endemo-epidemic. Several cases were reported in human patients for which infection due to L. major induced lesions with a broad range of severity. However, very little is known about the mechanisms underlying this diversity. Our hypothesis is that parasite genomic variability could, in addition to the host immunological background, contribute to the intra-species clinical variability observed in patients and explain the lesion size differences observed in the experimental model. Based on several epidemiological, in vivo and in vitro experiments, we focused on two clinical isolates showing contrasted severity in patients and BALB/c experimental mice model. We used DNA-seq as a high-throughput technology to facilitate the identification of genetic variants with discriminating potential between both isolates. Our results demonstrate that various levels of heterogeneity could be found between both L. major isolates in terms of chromosome or gene copy number variation (CNV), and that the intra-species divergence could surprisingly be related to single nucleotide polymorphisms (SNPs) and Insertion/Deletion (InDels) events. Interestingly, we particularly focused here on genes affected by both types of variants and correlated them with the observed gene CNV. Whether these differences are sufficient to explain the severity in patients is obviously still open to debate, but we do believe that additional layers of -omic information is needed to complement the genomic screen in order to draw a more complete map of severity determinants.

    Infants with the severe variant of glucose-6-phosphate dehydrogenase (G6PD) deficiency may develop hyperbilirubinaemia sufficiently severe to cause kernicterus and death, acute haemolysis on exposure to oxidant stress, congenital non-spherocytic haemolytic anaemia and, rarely, increased susceptibility to bacterial infection. In spite of these potential problems, G6PD deficiency is often not included among screening programmes for inherited disorders. In a comprehensive screening and educational programme, we tested around 34,000 infants for G6PD deficiency. Of the total group, 18.4% (24.5% boys and 11.8% girls) were deficient. Forty-two of the 6246 (0.67%) G6PD-deficient infants required exchange transfusion. None of them developed kernicterus. By contrast, of 4755 infants who had not been screened because they were born at home, three developed kernicterus. In addition, four G6PD-deficient infants had developed kernicterus in the 20-month period prior to the screening programme. None of the hyperbilirubinaemic infants had blood group incompatibility or any other identifiable cause of hyperbilirubinaemia. To avoid this disastrous result, we believe that neonatal screening for G6PD deficiency, together with a comprehensive education programme, is advisable in those parts of the world where the severe variant of G6PD deficiency is prevalent.

    Dystrophinopathy is one of the most common human monogenic diseases which results in Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD). Mutations in the dystrophin gene are responsible for both DMD and BMD. However, the clinical phenotypes and treatments are quite different in these two muscular dystrophies. Since early diagnosis and treatment results in better clinical outcome in DMD it is essential to establish accurate early diagnosis of DMD to allow efficient management. Previously, the reading-frame rule was used to predict DMD versus BMD. However, there are limitations using this traditional tool. Here, we report a novel molecular method to improve the accuracy of predicting clinical phenotypes in dystrophinopathy. We utilized several additional molecular genetic rules or patterns such as "ambush hypothesis", "hidden stop codons" and "exonic splicing enhancer (ESE)" to predict the expressed clinical phenotypes as DMD versus BMD. A computer software "DMDtoolkit" was developed to visualize the structure and to predict the functional changes of mutated dystrophin protein. It also assists statistical prediction for clinical phenotypes. Using the DMDtoolkit we showed that the accuracy of predicting DMD versus BMD raised about 3% in all types of dystrophin mutations when compared with previous methods. We performed statistical analyses using correlation coefficients, regression coefficients, pedigree graphs, histograms, scatter plots with trend lines, and stem and leaf plots. We present a novel DMDtoolkit, to improve the accuracy of clinical diagnosis for DMD/BMD. This computer program allows automatic and comprehensive identification of clinical risk and allowing them the benefit of early medication treatments.

    To characterize rectal histology in an inception cohort of children newly diagnosed with ulcerative colitis (UC) and to explore its relationship with clinical indices of disease severity. The PROTECT (Predicting Response to Standardized Pediatric Colitis Therapy) Study enrolled children 17 years of age and younger newly diagnosed with UC. Baseline rectal biopsies were evaluated for acute and chronic inflammation, eosinophilic inflammation (peak eosinophil count > 32 eosinophils/high powered field, eosinophilic cryptitis or abscesses), and architectural/nonarchitectural chronic changes. Correlation with clinical indices including Mayo endoscopy subscore and Pediatric Ulcerative Colitis Activity Index was performed. Rectal biopsies from 369 patients (mean age, 12.9±3.1 y, 50% female) were reviewed. Cryptitis was found in 89%, crypt abscesses in 25%, and eosinophilic inflammation in 58%. Crypt distortion/atrophy was present in 98% of specimens. Higher grades of acute and chronic inflammation were associated with the presence of basal plasmacytosis (P<0.0001), basal lymphoid aggregates (P<0.0001), and surface villiform changes (P<0.0001). A severe Mayo endoscopy subscore was most common among those with severe acute and chronic inflammation, although this relationship was not linear. Severe Pediatric Ulcerative Colitis Activity Index scores were associated with the absence of or only mild eosinophilic inflammation (<32 eosinophils/high powered field) (P<0.03) and the presence of surface villiform changes (P<0.005). Acute and chronic inflammation, eosinophilic inflammation and chronic changes are common in children newly diagnosed with UC. The clinical and biological implication of low to absent eosinophilic inflammation and the presence of surface villiform changes requires further study.

    Full Text Available Background: Pulmonary TB is an infectious disease of the respiratory tract caused by bacteria. Dental health professionals such as dentists and dental nurses are in charge of health personnel to prevent, treat, cure, teeth the mouth, so as not to arise or aggravate toothache. In doing their job as dental health workers is expected to use gloves or masks, and always wash their hands to avoid the transmission of pulmonary TB disease. Methods: A cross sectional study was conducted involving 78 dental health professionals in 50 primary health centers that were chosen in six districts in three provinces of Banten, South Kalimantan and Gorontalo. Data were obtained by interviews and processed using SPSSResults: More than 90% dental health workers in work wore masks gloves and washed their hands after work. There was a signifi cant relationship between exercise with dental health professionals with a p value of 0.007, which means a signifi cant. Conclusion: In performing their duties, dental health workers have already used personal protective equipment such asmasks, gloves, and washed their hands and did enough exercise. Recommendation: need to increase knowledge about pulmonary TB in dental health professionals.

    2008-02-01

    Full Text Available Abstract Background Autism Spectrum Conditions (ASCs are characterized by a high degree of clinical heterogeneity, but the extent to which this variation represents a severity gradient versus discrete phenotypes is unclear. This issue has complicated genetic studies seeking to investigate the genetic basis of the high hereditability observed clinically in those with an ASC. The aim of this study was to examine the possible clustering of symptoms associated with ASCs to determine whether the observed distribution of symptom type and severity supported either a severity or a symptom subgroup model to account for the phenotypic variation observed within the ASCs. Methods We investigated the responses of a group of adults with higher functioning ASCs on the fifty clinical features examined in the Autism Spectrum Quotient, a screening questionnaire used in the diagnosis of higher functioning ASCs. In contrast to previous studies we have used this instrument with no a priori assumptions about any underlying factor structure of constituent items. The responses obtained were analyzed using complete linkage hierarchical cluster analysis. For the members of each cluster identified the mean score on each Autism Spectrum Quotient question was calculated. Results Autism Spectrum Quotient responses from a total of 333 individuals between the ages of 16.6 and 78.0 years were entered into the hierarchical cluster analysis. The four cluster solution was the one that generated the largest number of clusters that did not also include very small cluster sizes, defined as a membership comprising 10 individuals or fewer. Examination of these clusters demonstrated that they varied in total Autism Spectrum Quotient but that the profiles across the symptoms comprising the Autism Spectrum Quotient did not differ independently of this severity factor. Conclusion These results are consistent with a unitary spectrum model, suggesting that the clinical heterogeneity observed

    The involvement of autonomic imbalance has been reported in the pathogenesis of allergic diseases. To investigate the association between the clinical severity of childhood allergic rhinitis and autonomic nervous system (ANS) dysfunction, to define whether the severity of disease correlates with ANS activity. In this cross-sectional, case-control study, we evaluated the ANS testing by measuring sympathetic skin response (SRR) and heart rate (R-R) interval variation (RRIV) in 55 children with perennial allergic rhinitis (PAR), aged 7-12 yrs without any chronic co-morbidity, and the results were compared with 40 sex- and age-matched control subjects. The patients were divided into two groups according to the severity of allergic rhinitis. There were significant increase in calculated RRIV variables during at rest and deep breathing in children with PAR compared to controls, which reflect parasympathetic nervous system (PNS) activity (p0.05). Lower RRIV and the prolonged SSR latencies in children with AR were closely correlated with disease severity (r=-0.65, p<0.05, and r=-0.59, p<0.05 respectively). Combined use of these two tests, allows separate testing of PNS and SNS function, and are very sensitive methods in assessing of severity of disease in children with PAR.

    Increasing the vertical dimension is essential to resolving problems associated with deep bite. Restorative dentistry, orthodontia, and oral surgery are the three disciplines that can help to gain the vertical dimension necessary in these patients. This clinical report presents the results of increasing vertical dimension with a full-mouth restorative treatment procedure for a 40-year-old male patient who exhibited severe deep bite. After clinical evaluation, extraoral examination showed a reduction of the lower facial height and protuberant lips, wrinkles, drooping, and overclosed commissures. In addition, intraoral examination showed a severe anterior deep-bite articulation, and upper incisors were in contact with the lower incisor labial tissue. A removable partial denture was made at increased occlusal vertical dimension (OVD) to use in the first stage of rehabilitation. Diagnostic wax-up was performed at the increased vertical dimension. Then, provisional crowns were fabricated according to this increased vertical dimension. Interim prostheses were used for 3 months as a guide for preparing the definitive restorations. The adaptation of the patient to the increased OVD was evaluated. During this period, he was asymptomatic. Following the evaluation period, definitive restorations were completed, and routine clinical assessments were made after 1 week, 1 month, 3 months, and 6 months, then after 1 and 2 years with visual and radiographic examinations. © 2014 by the American College of Prosthodontists.

    Objective: To determine whether the severity of non-neurological critically ill patients correlates with clinical predictors of bronchial aspiration. Methods: We evaluated adults undergoing prolonged orotracheal intubation (> 48 h) and bedside swallowing assessment within the first 48 h after extubation. We collected data regarding the risk of bronchial aspiration performed by a speech-language pathologist, whereas data regarding the functional level of swallowing were collected with the American Speech-Language-Hearing Association National Outcome Measurement System (ASHA NOMS) scale and those regarding health status were collected with the Sequential Organ Failure Assessment (SOFA). Results: The study sample comprised 150 patients. For statistical analyses, the patients were grouped by ASHA NOMS score: ASHA1 (levels 1 and 2), ASHA2 (levels 3 to 5); and ASHA3 (levels 6 and 7). In comparison with the other patients, those in the ASHA3 group were significantly younger, remained intubated for fewer days, and less severe overall clinical health status (SOFA score). The clinical predictors of bronchial aspiration that best characterized the groups were abnormal cervical auscultation findings and cough after swallowing. None of the patients in the ASHA 3 group presented with either of those signs. Conclusions: Critically ill patients 55 years of age or older who undergo prolonged orotracheal intubation (≥ 6 days), have a SOFA score ≥ 5, have a Glasgow Coma Scale score ≤ 14, and present with abnormal cervical auscultation findings or cough after swallowing should be prioritized for a full speech pathology assessment.

    A scoring classification for assessment of the clinical severity of reflex sympathetic dystrophy (RSD) and rating the presence and clinical expression of each feature is proposed. The following were included: pain, reduction of finger flexion, swelling, temperature changes, discoloration, sensory disturbances, shoulder pain and loss of movement, increased sweating, and hair/nail growth changes. For most of these features one point was assigned for strong expression, half a point for moderate expression, and zero points if the feature was absent. A score of four points was assumed, empirically, to indicate a minimal degree of RSD, and the maximum score of 10.5 to indicate fully symptomatic condition. One hundred forty-six patients with RSD of the hand were classified according to those criteria. Seventy-four patients (51%) had a score of 4-6, 51 patients (35%) of 6.5-8, and 21 patients (14%) of 8.5-10. This classification was then used to investigate the influence of clinical severity of RSD on the intensity of uptake of the tracer in three-phase bone scintigraphy. No correlation between RSD score values and intensity of fixation of the radionuclide was found.

  8. Automated Classification of Severity in Cardiac Dyssynchrony Merging Clinical Data and Mechanical Descriptors

    Full Text Available Cardiac resynchronization therapy (CRT improves functional classification among patients with left ventricle malfunction and ventricular electric conduction disorders. However, a high percentage of subjects under CRT (20%–30% do not show any improvement. Nonetheless the presence of mechanical contraction dyssynchrony in ventricles has been proposed as an indicator of CRT response. This work proposes an automated classification model of severity in ventricular contraction dyssynchrony. The model includes clinical data such as left ventricular ejection fraction (LVEF, QRS and P-R intervals, and the 3 most significant factors extracted from the factor analysis of dynamic structures applied to a set of equilibrium radionuclide angiography images representing the mechanical behavior of cardiac contraction. A control group of 33 normal volunteers (28±5 years, LVEF of 59.7%±5.8% and a HF group of 42 subjects (53.12±15.05 years, LVEF < 35% were studied. The proposed classifiers had hit rates of 90%, 50%, and 80% to distinguish between absent, mild, and moderate-severe interventricular dyssynchrony, respectively. For intraventricular dyssynchrony, hit rates of 100%, 50%, and 90% were observed distinguishing between absent, mild, and moderate-severe, respectively. These results seem promising in using this automated method for clinical follow-up of patients undergoing CRT.

    Gingival recession is an unsightly condition due to root exposure. It can lead to dental hypersensitivity, root caries, and tooth loss. To determine the influence of different clinical and periodontal parameters on the severity of gingival recession evaluated at four periods: initial, 6, 12, and 18 months of follow-up. Forty patients with gingival recession were included in the study. Sociodemographic data, systemic diseases, harmful habits, dental hygiene habits, parafunctional habits, and orthodontic treatment were collected. Periodontal status (plaque index, gingival bleeding index, attached gingiva loss, pocket probing depth, and attachment loss) was also measured. None of the clinical parameters studied influenced the number of teeth with gingival recession. Smokers showed a higher number of teeth with attached gingiva loss (p=0.03). A direct relationship between the severity of gingival recession and plaque index (p=0.02) or 4-6 mm attachment loss (p=0.04) was observed. At six months of follow-up, gingival index was the only parameter that influenced the severity of gingival recession (p=0.01).

    Full Text Available ObjectiveTo study the change in serum CRP level in patients with severe acute pancreatitis (SAP, and to explore its clinical significance in predicting outcomes and assessing the severity of SAP. MethodsA retrospective analysis was performed on 52 SAP patients with complete case data and admitted to General Hospital of Shenyang Military Area Command from September 2013 to September 2014. Blood drawing was performed and serum CRP concentration was determined on admission and at 24, 48, 72, 96, 120, and 144 hours after admission. The pattern of its dynamic change was observed. ResultsSerum CRP level in SAP patients significantly increased, and had a positive correlation with clinical outcomes. Forty-two cases (80.77% gradually recovered with aggressive treatment and the serum CRP levels were also slowly reduced (P<0.05. The serum CRP levels in four death cases (7.7% had no significant decrease and was maintained at a high level (P<0.05. Six patients (11.53% had aggravated conditions and recovered after aggressive treatment; meanwhile, the serum CRP levels first increased and then decreased (P<0.05. ConclusionFor SAP patients, serum CRP level fluctuates as their conditions change and can be considered as an important reference index for evaluating the severity and judging the outcomes of SAP.

    More than half of the hospitalizations because of dengue in Brazil occurred in children <15 years of age in 2007 and 2008, an unexpected change in the epidemiological pattern. We sought to determine clinical and laboratory parameters associated with severity. A case-control study was conducted in three pediatric hospitals in Rio de Janeiro, Brazil; 233 laboratory-confirmed dengue patients were included: 69 cases and 164 controls. Specific clinical and laboratory factors were assessed using univariate and multivariate logistic regression models. Lethargy [adjusted odds ratio (ORa): 9.15, 95% confidence interval (CI): 3.08-27.12], dyspnea (ORa: 8.24, 95% CI: 3.27-20.72) and abdominal pain (ORa: 6.78, 95% CI: 1.44-31.84) were independently associated with severe dengue in children. Lethargy and dyspnea presented as early as 72 and 48 h, respectively, before shock. Abdominal pain and lethargy confirmed their role as warning signs, which along with dyspnea might be helpful in identifying cases progressing to severe dengue. © The Author [2017].

    Anaphylaxis is a life-threatening allergic reaction. Several studies reported different anaphylactic reactions according to the causative substances. However, a comparison of anaphylaxis for each cause has not been done. This study was conducted to identify common causes of anaphylaxis, characteristics of anaphylactic reaction for each cause and to analyze the factors related to the severity of the reaction. Medical records of patients who visited the emergency room of Ewha Womans University Mokdong Hospital from March 2003 to April 2016 and diagnosed with anaphylactic shock were retrospectively reviewed. We compared the clinical features of anaphylaxis according to the cause. In addition, the severity of anaphylaxis was analyzed and contributing factors for severe anaphylaxis were reviewed. A total of 199 patients with anaphylaxis were analyzed. Food was the most common cause (49.7%), followed by drug reaction (36.2%), bee venom (10.1%), and unknown cause (4.0%). Cardiovascular symptoms of syncope and hypotension were more common in drug-induced anaphylaxis. The incidence of severe anaphylaxis was the highest in anaphylaxis due to drugs (54.2%). Urticaria and other skin symptoms were significantly more common in food-induced anaphylaxis. Risk factors for severe anaphylaxis included older age, male, and drug-induced one. Epinephrine treatment of anaphylaxis was done for 69.7% and 56.9% of patients with food-induced and drug-induced anaphylaxis, respectively. More severe anaphylaxis developed with drug treatment and in males. Low rate of epinephrine prescription was also observed. Male patients with drug induced anaphylaxis should be paid more attention.

    Rural-urban disparities in provision of preventive services exist, but there is sparse research on how rural, suburban, or urban differences impact physician adherence to clinical preventive service guidelines. We aimed to identify factors that may cause differences in adherence to preventive service guidelines among rural, suburban, and urban primary care physicians. This qualitative study involved in-depth semistructured interviews with 29 purposively sampled primary care physicians (10 rural, 10 suburban, 9 urban) in Missouri. Physicians were asked to describe barriers and facilitators to clinical preventive service guideline adherence. Using techniques from grounded theory analysis, 2 coders first independently conducted content analysis then reconciled differences in coding to ensure agreement on intended meaning of transcripts. Patient epidemiologic differences, distance to health care services, and care coordination were reported as prominent factors that produced differences in preventive service guideline adherence among rural, suburban, and urban physicians. Epidemiologic differences impacted all physicians, but rural physicians highlighted the importance of occupational risk factors in their patients. Greater distance to health care services reduced visit frequency and was a prominent barrier for rural physicians. Care coordination among health care providers was problematic for suburban and urban physicians. Patient resistance to medical care and inadequate access to resources and specialists were identified as barriers by some rural physicians. The rural, suburban, or urban context impacts whether a physician will adhere to clinical preventive service guidelines. Efforts to increase guideline adherence should consider the barriers and facilitators unique to rural, suburban, or urban areas. © 2013 National Rural Health Association.

    The purpose of this study was to construct and test a structural equation model for pressure ulcer prevention action by clinical nurses. The Health Belief Model and the Theory of Planned Behavior were used as the basis for the study. A structured questionnaire was completed by 251 clinical nurses to analyze the relationships between concepts of perceived benefits, perceived barriers, attitude, subjective norm, perceived control, intention to perform action and behavior. SPSS 22.0 and AMOS 22.0 programs were used to analyze the efficiency of the hypothesized model and calculate the direct and indirect effects of factors affecting pressure ulcer prevention action among clinical nurses. The model fitness statistics of the hypothetical model fitted to the recommended levels. Attitude, subjective norm and perceived control on pressure ulcer prevention action explained 64.2% for intention to perform prevention action. The major findings of this study indicate that it is essential to recognize improvement in positive attitude for pressure ulcer prevention action and a need for systematic education programs to increase perceived control for prevention action.

  15. Severe acute dehydration in a desert rodent elicits a transcriptional response that effectively prevents kidney injury.

    Animals living in desert environments are forced to survive despite severe heat, intense solar radiation, and both acute and chronic dehydration. These animals have evolved phenotypes that effectively address these environmental stressors. To begin to understand the ways in which the desert-adapted rodent Peromyscus eremicus survives, reproductively mature adults were subjected to 72 h of water deprivation, during which they lost, on average, 23% of their body weight. The animals reacted via a series of changes in the kidney, which included modulating expression of genes responsible for reducing the rate of transcription and maintaining water and salt balance. Extracellular matrix turnover appeared to be decreased, and apoptosis was limited. In contrast to the canonical human response, serum creatinine and other biomarkers of kidney injury were not elevated, suggesting that changes in gene expression related to acute dehydration may effectively prohibit widespread kidney damage in the cactus mouse.

    To study: (i) acute computed tomography (CT) characteristics and clinical outcome; (ii) clinical course and (iii) Corticosteroid Randomisation after Significant Head Injury acute calculator protocol (CRASH) model and clinical outcome in patients with severe traumatic brain injury (sTBI). Initial CT (CT i ) and CT 24 hours post-trauma (CT 24 ) were evaluated according to Marshall and Rotterdam classifications. Rancho Los Amigos Cognitive Scale-Revised (RLAS-R) and Glasgow Outcome Scale Extended (GOSE) were assessed at three months and one year post-trauma. The prognostic value of the CRASH model was evaluated. Thirty-seven patients were included. Marshall CT i and CT 24 were significantly correlated with RLAS-R at three months. Rotterdam CT 24 was significantly correlated with GOSE at three months. RLAS-R and the GOSE improved significantly from three months to one year. CRASH predicted unfavourable outcome at six months for 81% of patients with bad outcome and for 85% of patients with favourable outcome according to GOSE at one year. Neither CT nor CRASH yielded clinically useful predictions of outcome at one year post-injury. The study showed encouragingly many instances of significant recovery in this population of sTBI. The combination of lack of reliable prognostic indicators and favourable outcomes supports the case for intensive acute management and rehabilitation as the default protocol in the cases of sTBI.

    Probiotics are live microorganisms that may confer health benefits when ingested. Randomized trials suggest that probiotics significantly decrease the incidence of ventilator-associated pneumonia (VAP) and the overall incidence of infection in critically ill patients. However, these studies are small, largely single-center, and at risk of bias. The aim of the PROSPECT pilot trial was to determine the feasibility of conducting a larger trial of probiotics to prevent VAP in mechanically ventilated patients in the intensive care unit (ICU). In a randomized blinded trial, patients expected to be mechanically ventilated for ≥72 hours were allocated to receive either 1 × 10(10) colony-forming units of Lactobacillus rhamnosus GG or placebo, twice daily. Patients were excluded if they were at increased risk of L. rhamnosus GG infection or had contraindications to enteral medication. Feasibility objectives were: (1) timely recruitment; (2) maximal protocol adherence; (3) minimal contamination; and (4) estimated VAP rate ≥10 %. We also measured other infections, diarrhea, ICU and hospital length of stay, and mortality. Overall, in 14 centers in Canada and the USA, all feasibility goals were met: (1) 150 patients were randomized in 1 year; (2) protocol adherence was 97 %; (3) no patients received open-label probiotics; and (4) the VAP rate was 19 %. Other infections included: bloodstream infection (19.3 %), urinary tract infections (12.7 %), and skin and soft tissue infections (4.0 %). Diarrhea, defined as Bristol type 6 or 7 stools, occurred in 133 (88.7 %) of patients, the median length of stay in ICU was 12 days (quartile 1 to quartile 3, 7-18 days), and in hospital was 26 days (quartile 1 to quartile 3, 14-44 days); 23 patients (15.3 %) died in the ICU. The PROSPECT pilot trial supports the feasibility of a larger trial to investigate the effect of L. rhamnosus GG on VAP and other nosocomial infections in critically ill patients. Clinicaltrials

    To compares the clinical features of patients infected with hepatitis E virus (HEV) with or without severe jaundice. In addition, the risk factors for HEV infection with severe jaundice were investigated. We enrolled 235 patients with HEV into a cross-sectional study using multi-stage sampling to select the study group. Patients with possible acute hepatitis E showing elevated liver enzyme levels were screened for HEV infection using serologic and molecular tools.HEV infection was documented by HEV antibodies and by the detection of HEV-RNA in serum. We used χ(2) analysis, Fisher's exact test, and Student's t test where appropriate in this study. Significant predictors in the univariate analysis were then included in a forward, stepwise multiple logistic regression model. No significant differences in symptoms, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, or hepatitis B virus surface antigen between the two groups were observed. HEV infected patients with severe jaundice had significantly lower peak serum levels of γ-glutamyl-transpeptidase (GGT) (median: 170.31 U/L vs 237.96 U/L, P = 0.007), significantly lower ALB levels (33.84 g/L vs 36.89 g/L, P = 0.000), significantly lower acetylcholine esterase (CHE) levels (4500.93 U/L vs 5815.28 U/L, P = 0.000) and significantly higher total bile acid (TBA) levels (275.56 μmol/L vs 147.03 μmol/L, P = 0.000) than those without severe jaundice. The median of the lowest point time tended to be lower in patients with severe jaundice (81.64% vs 96.12%, P = 0.000). HEV infected patients with severe jaundice had a significantly higher viral load (median: 134 vs 112, P = 0.025) than those without severe jaundice. HEV infected patients with severe jaundice showed a trend toward longer median hospital stay (38.17 d vs 18.36 d, P = 0.073). Multivariate logistic regression indicated that there were significant differences in age, sex, viral load, GGT, albumin, TBA, CHE, prothrombin index, alcohol

    Neovascularization is frequently observed in tendinopathy. Previous studies have focused on the role of neovascularization in Achilles tendinopathy, but have been conducted in small series. It is still unclear whether the degree of neovascularization is related to severity of symptoms. The purpose was to study the relationship between ultrasonographic neovascularization and clinical severity in patients with Achilles tendinopathy. In this prospective cohort study, data on 127 patients (141 tendons) were assembled from databases of three clinical trials. All patients followed an eccentric exercise program. The Öhberg neovascularization score (0-4+) and Victorian Institute of Sports Assessment-Achilles (VISA-A) score (split into domains: pain, function and activity) were collected during baseline and follow-up. The relationship between neovascularization and VISA-A score was calculated. At baseline, 107 tendons (76%) showed some degree of neovascularization. In 556 coupled measurements, neovascularization was weakly related to the VISA-A score [Exp (B) 1.017, 95% confidence interval (CI), 1.007-1.026]. No significant relationship was found between neovascularization and the pain domain (P = 0.277) and the activity domain (P = 0.283), but there was between neovascularization and the function domain of the VISA-A score [Exp (B) = 1.067, 95% CI 1.018-1.119]. In conclusion, neovascularization in Achilles tendinopathy is weakly related to clinical severity, mainly based on the function domain of the VISA-A score. © 2013 John Wiley & Sons A/S.

    Full Text Available Clinical manifestations of hepatitis A virus (HAV infection vary from mild to fulminant hepatic failure (FHF in adults. We investigated the relationship between laboratory findings, including viral load, and clinical outcomes in patients with acute hepatitis A (AHA and evaluated predictive factors for severe acute hepatitis (s-AH.We analyzed the clinical manifestations of AHA in 770 patients. Patients with a prothrombin time (PT of less than 40% of normal were classified as s-AH and included 4 patients with FHF, 11 patients with acute renal failure, and 3 patients with prolonged jaundice (n = 128. Other patients were defined as mild acute hepatitis (m-AH (n = 642. Serum samples were obtained from 48 patients with acute hepatitis A. Among them, 20 with s-AH, and 28 with m-AH, were tested for HAV RNA titer.In a multivariate analysis, age (HR = 1.042, P = 0.041, peak creatinine (HR = 4.014, P = 0.001, bilirubin (HR = 1.153, P = 0.003, alanine aminotransferase (ALT (HR = 1.001, P < 0.001, initial lactate dehydrogenase (LDH (HR = 1.000, P = 0.045 and total cholesterol (HR = 0.978, P < 0.001 were independent factors for s-AH. Serum HAV RNA was detected in 20/20 (100% patients with s-AH and 22/28 (78.6% patients with m-AH. In a multivariate analysis of the 48 patients who were tested for HAV RNA, peak ALT (HR = 1.001, P = 0.004 and HAV RNA titer (HR = 2.076, P = 0.012 were independent factors for s-AH.Clinical factors including age, peak creatinine, bilirubin, ALT, initial LDH and total cholesterol were independent factors for s-AH in a multivariate analysis. In particular, HAV load strongly correlated with the severity of hepatitis A.

    Full Text Available Objective: The purpose of this presentation is to show the difficulty in prosthetization of a clinical case with a pronounced atrophy of the upper jaw and the various types and nature of restrictions imposed by the requirements of the patient. Methods: The clinical analysis, surgical protocol and prosthetic solution are presented in the treatment of 72 year-old woman with a pronounced atrophy of the upper jaw. OPG, standard CT of the upper jaw was used in the planning and a special surgical template was fabricated, helping us to find intraoperatively the exact locations of implants. The preliminary analysis of the number, height and diameter of intraossal implants helped us to find the exact prosthetic solution in this clinical case. The preparation of the implant bed was done by conical osteotomy in order to expand and condense the existing bone, which allowed us to use endoossal implants with a possible maximum size in a very limited maxillary volume and the reluctance of the patient to use other methods and surgical techniques. Conical threaded and self-tapping intraossal implants were used, placed according to a classic two-stage methodology with a flap and a long-term functional loading after a period of four months.Results and Conclusion: The applied surgical and prosthetic solution allowed us to achieve a good functional and aesthetic rehabilitation in this case of severe atrophy of the upper jaw, following a number of restrictions imposed on us by the reluctance of the patient to use other surgical solutions. This shows that in the case of severe atrophy of the upper jaw, a good clinical result can be achieved. For this reason, the use of CT,a well-planned surgical template, sufficient preparation ,the maximum use of available bone volume and the choice of a good prosthetic solution is very important.

    2010-10-15

    In the Spring of 2009, a veterinarian reported suspected classical swine fever (CSF) on a multiplier pig farm in the southern part of The Netherlands (close to the Belgian border). Over a 5-week period there had been a number of sick sows and an excessively high percentage of stillborn and preterm piglets. Sick animals were treated with anti-inflammatory drugs and antibiotics, but did not respond as well as anticipated. A visiting specialist team from the Food Safety Authority could not exclude CSF as the cause of the clinical problems and sent blood samples to the reference laboratory in Lelystad for a PCR test on CSF antigen. Fortunately, test results obtained 6 hours later were negative for CSF, and the disease control measures were lifted. It later appeared that porcine reproductive and respiratory syndrome (PRRSV) might have been responsible for the problems. But what if CSF had caused the clinical problems? A CSF-transmission model was used to simulate CSF outbreaks dependent on the duration of the high-risk period (HRP). As the duration of the HRP increased, there was an exponential growth in the number of pig farms infected during this period. Simulations also showed that with a longer HRP, the virus spread over greater distances from the source herd. It was also investigated whether a possible CSF outbreak could be detected on the basis of an increased mortality and hence increased number of cadavers sent to a rendering plant. However, the calculated mortality incidence was not sensitive enough to serve as an alarm signal. It is recommended that CSF-exclusion diagnostics be used much earlier in similar clinical situations on pig farms.

    Full Text Available Organ failure is an important factor causing death in patients with severe acute pancreatitis (SAP. In recent years, thanks to the further study of pathophysiology of SAP and the continuous accumulation of experience and technology, substantial progress has been made in the diagnosis and treatment of SAP complicated by organ failure. The clinical features of SAP complicated by organ failure and the measures to be strengthened in the treatment of SAP are summarized. Currently, it is thought that organ failure tends to appear once SAP occurs, so timely, standardized treatment can shorten the course of disease and significantly reduce mortality.

    In a retrospective cohort study, we tested the hypothesis that when prescribing hydroxyurea (HU) to children with sickle cell anemia (SCA) to prevent vaso-occlusive events, there will be a secondary benefit of maintaining low transcranial Doppler (TCD) velocity, measured by imaging technique (TCDi). HU was prescribed for 90.9% (110 of 120) of children with SCA ≥5 years of age and followed for a median of 4.4 years, with 70% (n = 77) receiving at least one TCDi evaluation after starting HU. No child prescribed HU had a conditional or abnormal TCDi measurement. HU initiation for disease severity prevention decreases the prevalence of abnormal TCDi velocities. © 2016 Wiley Periodicals, Inc.

    Full Text Available Objective: To assess the direct and indirect costs of diagnosing and treating community-acquired pneumonia (CAP, correlating those costs with CAP severity at diagnosis and identifying the major cost drivers. Methods: This was a prospective cost analysis study using bottom-up costing. Clinical severity and mortality risk were assessed with the pneumonia severity index (PSI and the mental Confusion-Urea-Respiratory rate-Blood pressure-age ≥ 65 years (CURB-65 scale, respectively. The sample comprised 95 inpatients hospitalized for newly diagnosed CAP. The analysis was run from a societal perspective with a time horizon of one year. Results: Expressed as mean ± standard deviation, in Euros, the direct and indirect medical costs per CAP patient were 696 ± 531 and 410 ± 283, respectively, the total per-patient cost therefore being 1,106 ± 657. The combined budget impact of our patient cohort, in Euros, was 105,087 (66,109 and 38,979 in direct and indirect costs, respectively. The major cost drivers, in descending order, were the opportunity cost (lost productivity; diagnosis and treatment of comorbidities; and administration of medications, oxygen, and blood derivatives. The CURB-65 and PSI scores both correlated with the indirect costs of CAP treatment. The PSI score correlated positively with the overall frequency of use of health care services. Neither score showed any clear relationship with the direct costs of CAP treatment. Conclusions: Clinical severity at admission appears to be unrelated to the costs of CAP treatment. This is mostly attributable to unwarranted hospital admission (or unnecessarily long hospital stays in cases of mild pneumonia, as well as to over-prescription of antibiotics. Authorities should strive to improve adherence to guidelines and promote cost-effective prescribing practices among physicians in southeastern Europe.

    To explore the clinical characteristics of IgA nephropathy (IgAN) with severe chronic periodontitis and aggressive periodontitis. A total of 436 hospitalized patients who underwent renal needle biopsy in the department of nephrology of China-Japan Friendship Hospital from November 2013 to December 2014 were recruited in the study and blindly had periodontal examination. The patients were divided into IgAN group and non-IgAN group according to the renal pathology. The patients with IgAN were further categorized as non-periodontitis, chronic periodontitis and aggressive peridontitis group by Haas classification. The chronic periodontitis group was continually divided into mild, moderate and severe periodontitis group. The levels of interleukin (IL)-1β and IL-6 in gingival crevicular fluid were analyzed by enzyme-linked immunosorbent assays. The prevalence of periodontitis in the study was 88.3% (385/436). The prevalence of chronic periodontitis and aggressive periodontitis were higher in patients with IgAN than those with non-IgAN (Pperiodontitis was correlated with pathologic grading of IgAN (r=0.48, Pperiodontitis, those with severe chronic and aggressive periodontitis had more severe pathology, more frequent recurrent gross hematuria, higher levels of 24 h proteinuria, serum triglyceride and uric acid, higher periodontal probing depth and clinical attatchment level, as well as higer levels of IL-1β and IL-6, but had lower creatinine clearance rate (all Paggressive periodontitis was higher in patients with IgAN. Chronic periodontitis is correlated with the onset and development of IgAN. Patients with IgAN have worse condition with the aggravation of periodontitis.

    Full Text Available Pneumonia is the most frequent type of infection in cancer patients and a frequent cause of ICU admission. The primary aims of this study were to describe the clinical and microbiological characteristics and outcomes in critically ill cancer patients with severe pneumonia.Prospective cohort study in 325 adult cancer patients admitted to three ICUs with severe pneumonia not acquired in the hospital setting. Demographic, clinical and microbiological data were collected.There were 229 (71% patients with solid tumors and 96 (29% patients with hematological malignancies. 75% of all patients were in septic shock and 81% needed invasive mechanical ventilation. ICU and hospital mortality rates were 45.8% and 64.9%. Microbiological confirmation was present in 169 (52% with a predominance of Gram negative bacteria [99 (58.6%]. The most frequent pathogens were methicillin-sensitive S. aureus [42 (24.9%], P. aeruginosa [41(24.3%] and S. pneumonia [21 (12.4%]. A relatively low incidence of MR [23 (13.6%] was observed. Adequate antibiotics were prescribed for most patients [136 (80.5%]. In multivariate analysis, septic shock at ICU admission [OR 5.52 (1.92-15.84], the use of invasive MV [OR 12.74 (3.60-45.07] and poor Performance Status [OR 3.00 (1.07-8.42] were associated with increased hospital mortality.Severe pneumonia is associated with high mortality rates in cancer patients. A relatively low rate of MR pathogens is observed and severity of illness and organ dysfunction seems to be the best predictors of outcome in this population.

    Full Text Available Abstract Background Severe malaria is a major contributor of deaths in African children up to five years of age. One valuable tool to support health workers in the management of diseases is clinical practice guidelines (CPGs developed using robust methods. A critical assessment of the World Health Organization (WHO and Kenyan paediatric malaria treatment guidelines with quinine was undertaken, with a focus on the quality of the evidence and transparency of the shift from evidence to recommendations. Methods Systematic reviews of the literature were conducted using the Grading of Recommendations Assessment, Development and Evaluation (GRADE tool to appraise included studies. The findings were used to evaluate the WHO and Kenyan recommendations for the management of severe childhood malaria. Results The WHO 2010 malaria guidance on severe malaria in children, which informed the Kenyan guidelines, only evaluated the evidence on one topic on paediatric care using the GRADE tool. Using the GRADE tool, this work explicitly demonstrated that despite the established use of quinine in the management of paediatric cases of severe malaria for decades, low or very low quality evidence of important outcomes, but not critical outcomes such as mortality, have informed national and international guidance on the paediatric quinine dosing, route of administration and adverse effects. Conclusions Despite the foreseeable shift to artesunate as the primary drug for treatment of severe childhood malaria, the findings reported here reflect that the particulars of quinine therapeutics for the management of severe malaria in African children have historically been a neglected research priority. This work supports the application of the GRADE tool to make transparent recommendations and to inform advocacy efforts for a greater research focus in priority areas in paediatric care in Africa and other low-income settings.

    To evaluate the overall somatic involvement in patients with eating disorders (EDs). The medical records of 206 patients (age 15-56 years, 96.1% females) with diagnosis of anorexia nervosa (AN, n = 63, 30.6%), bulimia nervosa (BN, n = 78, 37.9%), or eating disorder not otherwise specified (EDNOS, n = 65, 31.6 %) were analyzed. A cumulative score of clinical severity (SCS) was computed according to the presence of physical, instrumental, and laboratory abnormalities, as well as to their prognostic impact. Based on the tertile distribution of SCS, three levels of severity were defined: low, medium, and high. A medium/high level of severity was found in 63% of the whole sample, 89% of AN, 49% of BN, and 55% of EDNOS. In the whole sample, the risk of medium/high SCS was significantly and inversely related to the body mass index (BMI) and to the lifetime minimum BMI. The severity level was significantly and positively associated with diagnosis of AN, duration of amenorrhea C1 year, and presence of ED-related symptoms. EDNOS patients showed a higher risk for increased SCS than BN patients, although not significantly. The non-negligible frequency of a relevant somatic involvement in patients with EDNOS suggests that a transdiagnostic scoring system might be helpful to identify ED cases at risk of medical complications.

    Background Hypoglycaemia is a poor prognostic indicator in severe malaria. Intravenous infusions are rarely feasible in rural areas. The efficacy of sublingual sugar (SLS) was assessed in a pilot randomized controlled trial among hypoglycaemic children with severe malaria in Mali. Methods Of 151 patients with presumed severe malaria, 23 children with blood glucose concentrations = 3.3 mmol/l (60 mg/dl) within 40 minutes after admission. Secondary outcome measures were early treatment response at 20 minutes, relapse (early and late), maximal BGC gain (CGmax), and treatment delay. Results There was no significant difference between the groups in the primary outcome measure. Treatment response occurred in 71% and 67% for SLS and IVG, respectively. Among the responders, relapses occurred in 30% on SLS at 40 minutes and in 17% on IVG at 20 minutes. There was one fatality in each group. Treatment failures in the SLS group were related to children with clenched teeth or swallowing the sugar, whereas in the IVG group, they were due to unavoidable delays in beginning an infusion (median time 17.5 min (range 3–40). Among SLS, the BGC increase was rapid among the nine patients who really kept the sugar sublingually. All but one increased their BGC by 10 minutes with a mean gain of 44 mg/dl (95%CI: 20.5–63.4). Conclusion Sublingual sugar appears to be a child-friendly, well-tolerated and effective promising method of raising blood glucose in severely ill children. More frequent repeated doses are needed to prevent relapse. Children should be monitored for early swallowing which leads to delayed absorption, and in this case another dose of sugar should be given. Sublingual sugar could be proposed as an immediate "first aid" measure while awaiting intravenous glucose. In many cases it may avert the need for intravenous glucose. PMID:19025610

    It becomes evident that severe accidents may occur by unexpected disasters such as tsunami, heavy flood, or terror. Once radioactive material is released from NPP through severe accidents, there are no ways to prevent the released radioactive gas spreading in the air. As a remedy for this problem, the idea on the portable filtered air suction system (PoFASS) for the prevention of released radioactive gas under severe accidents was proposed. In this paper, the conceptual design of a PoFASS focusing on the number of robot fingers and robot arm rods are proposed. In order to design a flexible robot suction nozzle, mathematical models for the gaps which represent the lifted heights of extensible covers for given convex shapes of pipes and for the covered areas are developed. In addition, the system requirements for the design of the robot arms of PoFASS are proposed, which determine the accessible range of leakage points of released radioactive gas. In this paper, the conceptual designs of the flexible robot suction nozzle and robot arm have been conducted. As a result, the minimum number of robot fingers and robot arm rods are defined to be four and three, respectively. For further works, extensible cover designs on the flexible robot suction nozzle and the application of the PoFASS to the inside of NPP should be studied because the radioactive gas may be released from connection pipes between the containment building and auxiliary buildings.

    The magnetic resonance examination was performed in 38 patients with severe cerebral palsy (CP; 15 males and 23 females) who had both motor delay (unable to move anywhere) and mental retardation (I.Q. or D.Q. below 30). Neuroimaging findings were compared with the CP type, etiology, and grade of understanding of language. Cranial magnetic resonance imagings (MRI) in CP were divided into five types. In type 1, nine predominantly showed cyst-liked ventricles and periventricular hyperintensity on T[sub 2]-weighted imaging (PVH) and only scarred basal ganglia and thalamus were visible. All suffered from neonatal asphyxia and the clinical type was rigospastic tetraplegia (RST). In type 2, eleven predominantly showed PVH and hyperintensity on T[sub 2]-weighted (HT2) in basal ganglia and thalamus. All suffered from neonatal asphyxia and the clinical type was RST or rigospastic diplegia. In type 3, five showed PVH and three had cortical atrophy. All suffered from neonatal asphyxia and the clinical type was spastic diplegia. In type 4, four predominantly showed HT2 in putamen and thalamus. Three had cortical atrophy. All suffered from neonatal asphyxia. The clinical type was athetotic CP (ATH). In type 5, nine predominantly showed HT2 in globus pallidus. Four had cortical atrophy and two had hippocampal atrophy. All suffered from neonatal jaundice and the clinical type was ATH. All patients who suffered from neonatal asphyxia and spastic CP had MRI in PVH. All patients who suffered from neonatal asphyxia and ATH showed HT2 in putamen and thalamus. Almost patients who suffered from neonatal jaundice and ATH showed HT2 in globus pallidus. With athetotic CP, cases with atrophy of the cerebral cortex and/or hippocampus were lower grade of understanding of language than no atrophy of both. The results of studies of MRI are in agreement with neuropathological findings. (author).

    The promise of combination HIV prevention-the application of multiple HIV prevention interventions to maximise population-level effects-has never been greater. However, to succeed in achieving significant reductions in HIV incidence, an additional concept needs to be considered: combination implementation. Combination implementation for HIV prevention is the pragmatic, localised application of evidence-based strategies to enable high sustained uptake and quality of interventions for prevention of HIV. In this Review, we explore diverse implementation strategies including HIV testing and counselling models, task shifting, linkage to and retention in care, antiretroviral therapy support, behaviour change, demand creation, and structural interventions, and discusses how they could be used to complement HIV prevention efforts such as medical male circumcision and treatment as prevention. HIV prevention and treatment have arrived at a pivotal moment when combination efforts might result in substantial enough population-level effects to reverse the epidemic and drive towards elimination of HIV. Only through careful consideration of how to implement and operationalise HIV prevention interventions will the HIV community be able to move from clinical trial evidence to population-level effects.

    Abstract The formulation of accurate clinical case definitions is an integral part of an effective process of public health surveillance. Although such definitions should, ideally, be based on a standardized and fixed collection of defining criteria, they often require revision to reflect new knowledge of the condition involved and improvements in diagnostic testing. Optimal case definitions also need to have a balance of sensitivity and specificity that reflects their intended use. After the 2009–2010 H1N1 influenza pandemic, the World Health Organization (WHO) initiated a technical consultation on global influenza surveillance. This prompted improvements in the sensitivity and specificity of the case definition for influenza – i.e. a respiratory disease that lacks uniquely defining symptomology. The revision process not only modified the definition of influenza-like illness, to include a simplified list of the criteria shown to be most predictive of influenza infection, but also clarified the language used for the definition, to enhance interpretability. To capture severe cases of influenza that required hospitalization, a new case definition was also developed for severe acute respiratory infection in all age groups. The new definitions have been found to capture more cases without compromising specificity. Despite the challenge still posed in the clinical separation of influenza from other respiratory infections, the global use of the new WHO case definitions should help determine global trends in the characteristics and transmission of influenza viruses and the associated disease burden.

    COPD is currently recognized as a syndrome associated with a high prevalence of comorbidities and various phenotypes. Exacerbations are very important events in the clinical history of COPD because they drive the decline in lung function. In the present study, we aim to identify whether there are any clinical and functional specific features of frequent exacerbators in a population of patients with severe COPD. We conducted a cross-sectional, case control study. All subjects had Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage 3 or 4 COPD (FEV 1 lower inspiratory capacity percentage predicted. The Motley index (residual volume/total lung capacity percentage) was significantly increased in frequent exacerbators. Infrequent exacerbators had lower Modified Medical Research Council dyspnea scale and BODE index than frequent exacerbators. In the multivariate model, a reduced inspiratory capacity percentage predicted and an increase of residual volume/total lung capacity percentage, BODE index and Modified Medical Research Council dyspnea scale were associated with the frequent exacerbation phenotype. Static hyperinflation and respiratory disability, measured by Motley index and Modified Medical Research Council dyspnea scale, respectively, in the same way as the multidimensional BODE index staging system, were independently associated with frequent exacerbation status in subjects with severe COPD.

    The main goal of this article was to evaluate if the decision to perform cranial computed tomography (CT) in children with minor head injury is determined by the presence or absence of the physician during assessment in the emergency room. Clinical files of 92 patients from 8 months to 4 years of age were selected. Those children were evaluated at the emergency department of the Spanish Hospital of Mexico due to non-severe traumatic brain injury. Glasgow Coma Scale (GCS) score was determined in all patients. Groups of patients were compared: 1) patients having CT, 2) patients with a physician who attended the initial assessment, 3) patients whose attending physician did not arrive to assess the patient and 4) patients assessed by the emergency room staff. 38% of patients with non-severe brain injury underwent CT, 8.6% had a brain injury visible on the CT. Moderate intensity impacts were greater in patients with CT. Regarding the ECG, it was found that most children scored 15 points (p=0.03). In patients without a physician, a greater trend was demonstrated for performing CT. Patients with minor head injury but without neurological signs should undergo a detailed clinical evaluation in order to avoid unwarranted CT. Copyright © 2015.

    To characterize prevalence and correlates of child maltreatment (CM) in a clinical sample of adolescents with severe obesity. Multicenter baseline data from 139 adolescents undergoing weight loss surgery (Mage = 16.9; 79.9% female, 66.2% White; Mbody mass index [BMI] = 51.5 kg/m(2)) and 83 nonsurgical comparisons (Mage = 16.1; 81.9% female, 54.2% White; MBMI = 46.9 kg/m(2)) documented self-reported CM (Childhood Trauma Questionnaire) and associations with psychopathology, quality of life, self-esteem and body image, high-risk behaviors, and family dysfunction.  CM prevalence (females: 29%; males: 12%) was similar to national adolescent base rates. Emotional abuse was most prevalent. One in 10 females reported sexual abuse. For females, CM rates were higher in comparisons, yet correlates were similar for both cohorts: greater psychopathology, substance use, and family dysfunction, and lower quality of life. While a minority of adolescents with severe obesity reported a CM history, they carry greater psychosocial burden into the clinical setting. © The Author 2015.

    Full Text Available Visual evoked potential (VEP is a technique used to assess the brain’s electrical response to visual stimuli. The aims of this study were to examine neural transmission within the visual pathway through VEP testing in preschool children with autism spectrum disorder (ASD and compare it to age-matched controls, as well as search for a correlation between the VEP parameters and the symptoms of ASD. Participants were composed of ASD children (9 males and typically developing children (8 males and 4 females, aged between 3 and 5 years. Checkerboards were chosen as the pattern-reversal VEP. The clinical severity of ASD was assessed using the Autism Treatment Evaluation Checklist (ATEC and the Vineland Adaptive Behavior Scales 2nd edition (VABS-II. Our findings demonstrated that children with ASD had significantly longer N145 latency compared to the controls. A longer N145 latency correlated with a higher score of ATEC within the sensory/cognitive awareness subdomain. In addition, a slower N145 response was also associated with a lower VABS-II score within the socialization domain. The correlation between longer VEP latency and abnormal behaviors in children with ASD suggests a delayed neural communication within other neural circuits, apart from the visual pathway. These lines of evidence support the possibility of using VEP, along with clinical parameters, for the assessment of ASD severity.

    This study not only evaluated the clinical effects of treatment using haploidentical hematopoietic stem cells (haplo-HSCs) combined with human umbilical cord mesenchymal stem cells (UC-MSCs) in patients with severe aplastic anemia (SAA), but also investigated the factors related to graft versus host disease (GVHD). Cotransplantation of haplo-HSCs and UC-MSCs was performed in 24 SAA patients. The conditioning regimens consisted of rabbit anti-human T-lymphocyte immunoglobulin (ATG), cyclophosphamide, and fludarabine with or without busulfan. GVHD was prevented using cyclosporine A, ATG, anti-CD25 monoclonal antibody, and mycophenolate material. The incidence of acute GVHD was 50%. The incidence of severe acute GVHD was not related to gender, age, donor-recipient relations, and patient/donor pair, while patient/donor pair (r = 0.541, P = 0.022) was significantly correlated with incidence of chronic GVHD. Upon follow-up for a median of 13 months, 5 of the 24 patients (20.8%) were dead. The survival rates at 3 and 6 months in all patients were 87.5% (21/24) and 83.3% (20/24), respectively. Cotransplantation of haplo-HSCs combined with UC-MSCs was an effective and safe approach for the treatment of patients with SAA. The appropriate conditioning regimen and early treatment for infection also played a critical role in the success of HSCT.

    Falls in older adults are the result of several risk factors across biological and behavioral aspects of the person, along with environmental factors. Falls can trigger a downward spiral in activities of daily living, independence, and overall health outcomes. Clinicians who care for older adults should screen them annually for falls. A multifactorial comprehensive clinical fall assessment coupled with tailored interventions can result in a dramatic public health impact, while improving older adult quality of life. For community-dwelling older adults, effective fall prevention has the potential to reduce serious fall-related injuries, emergency room visits, hospitalizations, institutionalization, and functional decline.

    Full Text Available Isoniazid (INH monotherapy has gained widespread acceptance as an efficacious therapy for latent tuberculosis infection (LTBI especially in low-prevalence settings. Although INH related hepatotoxicity is well recognized, progression to severe liver dysfunction requiring care at a transplant center remains unpredictable. We report the management of a five year-old girl who developed progressive liver failure due to INH prophylaxis. This highlights the potential severity of INH related hepatic injury and underscores the significance of vigilant clinical monitoring throughout the duration of the therapy in children.

  7. Predictive clinical factors in the diagnosis of gastrointestinal Kaposi's sarcoma and its endoscopic severity.

    Full Text Available BACKGROUND: The diagnosis of gastrointestinal (GI involvement in Kaposi's sarcoma (KS is important to make because the need for treatment depends on the extent of the disease. Moreover, severe GI lesions can cause serious complications. Endoscopy with biopsy is an extremely useful method to diagnose GI-KS. However, determining the indications for endoscopy is difficult because KS can occur without GI symptoms or cutaneous KS. This study sought to clarify predictive clinical factors for GI-KS and its severity on endoscopy. METHODOLOGY/PRINCIPAL FINDINGS: A total of 1,027 HIV-infected patients who underwent endoscopy were analyzed. Sexual behavior, CD4 count, HIV RNA, history of highly active antiretroviral therapy (HAART, GI symptoms, and cutaneous KS were assessed. Endoscopic severity including bulky tumor, ulceration, and number of lesions were evaluated. Thirty-three patients had GI-KS and 46 patients cutaneous KS. Among the GI-KS patients, 78.8% (26/33 had no GI symptoms and 24.2% (8/33 had no cutaneous KS. Univariate analysis identified men who have sex with men (MSM, CD4 <100 cells/µL, HIV RNA ≥10,000 copies/mL, no history of HAART, and cutaneous KS were significantly associated with GI-KS. Among these factors, cutaneous KS was closely related to GI-KS on multivariable analysis. Among patients without cutaneous KS, MSM and CD4 count <100 cells/µL were the only independent clinical factors related to GI-KS. Bulky tumor was significantly associated with CD4 <100 cells/µL and large number of lesions was significantly associated with HIV-RNA ≥10,000 copies/mL. CONCLUSIONS: To diagnose GI-KS, clinical factors need to be considered before endoscopy. The presence of GI symptoms is not useful in predicting GI-KS. MSM and CD4 count <100 cells/µL are predictive factors among patients without cutaneous KS. Caution should be exercised especially in patients with low CD4 counts or high HIV viral loads as they are more likely to develop severe GI

    Young adults with Internet gaming disorder (IGD) usually postpone the tasks of their daily lives to engage in Internet gaming. This study evaluates the association between procrastination and IGD and the association between the negative consequences of IGD and procrastination. We recruited 87 individuals with IGD and 87 controls without a history of IGD. All participants underwent a diagnostic interview based on the DSM-5 IGD criteria to assess the clinical global score. They also completed questionnaires regarding IGD, procrastination, impulsivity, depression, and hostility. Young adults with IGD had higher levels of procrastination. Procrastination was positively associated with depression, hostility, and impulsivity. After controlling for depression, hostility, and impulsivity, procrastination was still found to be associated with IGD. Further, procrastination was positively associated with the clinical global impressions score among young adults with IGD. Procrastination is associated with IGD independent of depression, hostility, and impulsivity. Procrastination is also associated with the clinical severity of IGD. The results suggest that procrastination should be carefully evaluated and intervention should be taken with young adults with IGD. This intervention might attenuate the negative consequences of IGD.

    Background and Aims Clinical manifestations of hepatitis A virus (HAV) infection vary from mild to fulminant hepatic failure (FHF) in adults. We investigated the relationship between laboratory findings, including viral load, and clinical outcomes in patients with acute hepatitis A (AHA) and evaluated predictive factors for severe acute hepatitis (s-AH). Methods We analyzed the clinical manifestations of AHA in 770 patients. Patients with a prothrombin time (PT) of less than 40% of normal were classified as s-AH and included 4 patients with FHF, 11 patients with acute renal failure, and 3 patients with prolonged jaundice (n = 128). Other patients were defined as mild acute hepatitis (m-AH) (n = 642). Serum samples were obtained from 48 patients with acute hepatitis A. Among them, 20 with s-AH, and 28 with m-AH, were tested for HAV RNA titer. Results In a multivariate analysis, age (HR = 1.042, P = 0.041), peak creatinine (HR = 4.014, P = 0.001), bilirubin (HR = 1.153, P = 0.003), alanine aminotransferase (ALT) (HR = 1.001, Phepatitis A.

    Latent equine herpesvirus type 1 (EHV-1) infection is common in horse populations worldwide and estimated to reach a prevalence nearing 90% in some areas. The virus causes acute outbreaks of disease that are characterized by abortion and sporadic cases of myeloencephalopathy (EHM), both severe threats to equine facilities. Different strains vary in their abortigenic and neuropathogenic potential and the simultaneous occurrence of EHM and abortion is rare. In this report, we present clinical observations collected during an EHV-1 outbreak caused by a so-called "neuropathogenic" EHV-1 G(2254)/D(752) polymerase (Pol) variant, which has become more prevalent in recent years and is less frequently associated with abortions. In this outbreak with 61 clinically affected horses, 6/7 pregnant mares aborted and 8 horses developed EHM. Three abortions occurred after development of EHM symptoms. Virus detection was performed by nested PCR targeting gB from nasal swabs (11 positive), blood serum (6 positive) and peripheral blood mononuclear cells (9 positive) of a total of 42 horses sampled. All 6 fetuses tested positive for EHV-1 by PCR and 4 by virus isolation. Paired serum neutralization test (SNT) on day 12 and 28 after the index case showed a significant (≥ 4-fold) increase in twelve horses (n = 42; 28.6%). This outbreak with abortions and EHM cases on a single equine facility provided a unique opportunity for the documentation of clinical disease progression as well as diagnostic procedures.

    Full Text Available Severe malaria (SM is a major cause of death in sub-Saharan Africa. Identification of both specific and sensitive clinical features to predict death is needed to improve clinical management.A 13-year observational study was conducted from 1997 through 2009 of 2,901 children with SM enrolled at the Royal Victoria Teaching Hospital in The Gambia to identify sensitive and specific predictors of poor outcome in Gambian children with severe malaria between the ages 4 months to 14 years. We have measured the sensitivity and specificity of clinical features that predict death or development of neurological sequelae.Impaired consciousness (odds ratio {OR} 4.4 [95% confidence interval {CI}, 2.7-7.3], respiratory distress (OR 2.4 [95%CI, 1.7-3.2], hypoglycemia (OR 1.7 [95%CI, 1.2-2.3], jaundice (OR 1.9 [95%CI, 1.2-2.9] and renal failure (OR 11.1 [95%CI, 3.3-36.5] were independently associated with death in children with SM. The clinical features that showed the highest sensitivity and specificity to predict death were respiratory distress (area under the curve 0.63 [95%CI, 0.60-0.65] and impaired consciousness (AUC 0.61[95%CI, 0.59-0.63], which were comparable to the ability of hyperlactatemia (blood lactate>5 mM to predict death (AUC 0.64 [95%CI, 0.55-0.72]. A Blantyre coma score (BCS of 2 or less had a sensitivity of 74% and specificity of 67% to predict death (AUC 0.70 [95% C.I. 0.68-0.72], and sensitivity and specificity of 74% and 69%, respectively to predict development of neurological sequelae (AUC 0.72 [95% CI, 0.67-0.76].The specificity of this BCS threshold to identify children at risk of dying improved in children less than 3 years of age (AUC 0.74, [95% C.I 0.71-0.76].The BCS is a quantitative predictor of death. A BCS of 2 or less is the most sensitive and specific clinical feature to predict death or development of neurological sequelae in children with SM.

  12. Severe hypoxia induces chemo-resistance in clinical cervical tumors through MVP over-expression

    Full Text Available Abstract Oxygen molecule modulates tumour response to radiotherapy. Higher radiation doses are required under hypoxic conditions to induce cell death. Hypoxia may inhibit the non-homologous end-joining DNA repair through down regulating Ku70/80 expression. Hypoxia induces drug resistance in clinical tumours, although the mechanism is not clearly elucidated. Vaults are ribonucleoprotein particles with a hollow barrel-like structure composed of three proteins: major vault protein (MVP, vault poly(ADP-ribose polymerase, and telomerase associated protein-1 and small untranslated RNA. Over-expression of MVP has been associated with chemotherapy resistance. Also, it has been related to poor outcome in patients treated with radiotherapy alone. The aim of the present study was to assess the relation of Major Vault Protein expression and tumor hypoxia in clinical cervical tumors. MVP, p53 and angiogenesis, together with tumor oxygenation, were determined in forty-three consecutive patients suffering from localized cervix carcinoma. High MVP expression was related to severe hypoxia compared to low MVP expressing tumors (p = 0.022. Tumors over-expressing MVP also showed increased angiogenesis (p = 0.003. Besides it, in this study we show for the first time that severe tumor hypoxia is associated with high MVP expression in clinical cervical tumors. Up-regulation of MVP by hypoxia is of critical relevance as chemotherapy is currently a standard treatment for those patients. From our results it could be suggested that hypoxia not only induces increased genetic instability, oncogenic properties and metastatization, but through the correlation observed with MVP expression, another pathway of chemo and radiation resistance could be developed.

    Full Text Available Introduction: Although significant development in the field of medicine is achieved, sepsis is still a major issue threatening humans’ lives. This study was aimed to audit the management of severe sepsis and septic shock patients in emergency department (ED according to the present standard guidelines.Method: This is a prospective audit on approaching adult septic patients who were admitted to ED. The audit checklist was created based on the protocols of Surviving Sepsis Campaign and British Royal College recommendations. The mean knowledge score and the compliance rate of studied measures regarding standard protocols were calculated using SPSS version 21.Results: 30 emergency medicine residents were audited (63.3% male. The mean knowledge score of studied residents regarding standard guidelines were 5.07 ± 1.78 (IQR = 2 in pre education and 8.17 ± 1.31 (IQR = 85 in post education phase (p < 0.001. There was excellent compliance with standard in 4 (22% studied measures, good in 2 (11%, fair in 1 (6%, weak in 2 (11%, and poor in 9 (50%. 64% of poor compliance measures correlated to therapeutic factors. After training, score of 5 measures including checking vital signs in < 20 minute, central vein pressure measurement in < 1 hour, blood culture request, administration of vasopressor agents, and high flow O2 therapy were improved clinically, but not statistically.Conclusion: The protocol adherence in management of severe sepsis and septic shock for urine output measurement, central venous pressure monitoring, administration of inotrope agents, blood transfusion, intravenous antibiotic and hydration therapy, and high flow O2 delivery were disappointingly low. It seems training workshops and implementation of Clinical audit can improve residents’ adherence to current standard guidelines regarding severe sepsis and septic shock.

    The epidemiology and difficulties in diagnosing low back pain are discussed. Clinical investigations should be limited to those tests that will provide useful information for effective management. Prevention is the best strategy for avoiding low back pain but is realistically hard to practise because the disorder has many environmental and intrinsic risk factors.

    The aim of the study was to compare the incidence of the use of additional uterotonics before and after the change of carbetocin to oxytocin for the prevention of postpartum hemorrhage after cesarean delivery in women with severe preeclampsia. This was an observational retrospective before-and-after study. Operating room, postoperative recovery area. Sixty women with severe preeclampsia undergoing cesarean delivery under spinal anesthesia; American Society of Anesthesiologists 3. Observational study. Blood pressure, heart rate, and biological data (hemoglobin, platelets, haptoglobin, prothrombin time index, activated partial thromboplastin time ratio, blood uric acid, aspartate aminotransferase, alanine aminotransferase, serum urea, serum creatinine, and albumin). The incidence of additional uterotonic administration in the carbetocin and oxytocin groups was 15% and 10%, respectively (P=.70). As carbetocin appears to be as effective and safe as oxytocin in preeclamptic women, its advantages make it a good uterotonic option in this particular setting. Copyright © 2016 Elsevier Inc.

    Inflammatory bowel disease (IBD) comprising of ulcerative colitis (UC) and Crohn's disease (CD) is a major ailment affecting the small and large bowel. In clinics, IBD is treated using 5-amninosalicylates, antibiotics, the steroids and immunomodulators. Unfortunately, the long term usages of these agents are associated with undue side effects and compromise the therapeutic advantage. Accordingly, there is a need for novel agents that are effective, acceptable and non toxic to humans. Preclinical studies in experimental animals have shown that curcumin, an active principle of the Indian spice turmeric (Curcuma longa Linn) is effective in preventing or ameliorating UC and inflammation. Over the last few decades there has been increasing interest in the possible role of curcumin in IBD and several studies with various experimental models of IBD have shown it to be effective in mediating the inhibitory effects by scavenging free radicals, increasing antioxidants, influencing multiple signaling pathways, especially the kinases (MAPK, ERK), inhibiting myeloperoxidase, COX-1, COX-2, LOX, TNF-α, IFN-γ, iNOS; inhibiting the transcription factor NF-κB. Clinical studies have also shown that co-administration of curcumin with conventional drugs was effective, to be well-tolerated and treated as a safe medication for maintaining remission, to prevent relapse and improve clinical activity index. Large randomized controlled clinical investigations are required to fully understand the potential of oral curcumin for treating IBD.

    To facilitate early recognition of ominous clinical manifestations, to understand pathophysiology and assess treatment effects in patients with severe enterovirus 71 (EV71) associated hand, foot and mouth disease (HFMD). A retrospective analysis was performed based on the clinical records, laboratory data and treatment effects which were collected from twelve severe EV71 infected cases from nine hospitals in 2008, in Hubei province, China. Of the 12 severe cases, ten (83.3%) were male and two female. The median age was 1.96 yrs (8 m to 7 yrs). The mean hyperthermic duration was 6 days with the peak temperature over 38.5 degrees C, and mean rash duration was 7 days. Fever and rash emerged simultaneously in 4 of 5 cases with cardiopulmonary failure. The severe complications included encephalitis (10 cases), pulmonary edema or hemorrhage (5 cases). Eleven cases were checked with magnetic resonance imaging (MRI) and four cases showed characteristics of encephalitis or meningitis, two with images of naso sinusitis and ethmoid-mastoid inflammation. Chest X-ray examination showed with pulmonary edema on single or both sides (5 cases), bronchitis (4 cases), and normal image (3 cases). There was no specific finding in the cardiac ultrasound and electrocardiogram in any of the patients, as well as the white blood cell count, blood glucose, prothrombin time, partial thromboplastin time and D-dimer. Cerebrospinal fluid showed aseptic meningitis with the increase of cell count in 7 cases. All patients were treated with antibiotics and/or antivirals, such as cephalosporins, ribavirin etc. Eleven patients were treated with intravenous immunoglobulin (total dose 2 - 4.5 g/kg) for 2 - 5 days, and the highest blood concentration of immunoglobulin was detected increasing at 7 g/L. Seven cases were also treated with methylprednisolone 10 - 30 mg/(kg x d), four with dopamine, dobutamine, or digitalis. In addition, by using continuous positive airway pressure by nasal catheter and

    Hypertriglyceridaemia is a common biochemical abnormality that can be due to primary causes or, more commonly, secondary causes. Moderate hypertriglyceridaemia is a risk factor for cardiovascular disease and can develop into severe hypertriglyceridaemia which is a risk factor for acute pancreatitis. Familial chylomicronaemia is a rare autosomal recessive disorder, usually diagnosed in childhood and is characterized by marked hypertriglyceridaemia and biochemical deficiency of lipoprotein lipase (LPL), apolipoprotein (apo) C-II, homozygous (or compound heterozygous) gene mutations in LPL or more rarely, APOC2. Recently, loss-of-function mutations in the APOA5 gene have been reported in patients with severe hypertriglyceridaemia in whom LPL or APOC2 mutations were not found. We describe the clinical features and genetic analysis of three patients with severe hypertriglyceridaemia including novel mutations LPL c.464T>C (p.Leu155Pro) and APOA5 c.823C>T (p.Gln275*). © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Hypoglycaemia is an independent risk factor for death in severe malaria and a recognized adverse treatment effect of parenteral quinine. In 2006 our hospital changed quinine treatment policy from 15 mg/kg loading (plus 10 mg/kg 12-hourly) to 20 mg/kg loading (plus 10 mg/kg 8-hourly) to comply with new WHO guidelines. This presented us with the opportunity to examine whether there was any dose relationship of quinine and hypoglycaemia occurrence. Retrospective case notes review of all children admitted to hospital with severe falciparum malaria between April 2002 - July 2009, before and after the introduction of the new WHO quinine regimen. Four-hourly bedside glucose levels were measured until intravenous quinine was discontinued. Clinical events immediately preceding or concurrent with each episode of hypoglycaemia (glucose quinine regime and 283 received the new regime. We found no evidence of an increased prevalence of hypoglycaemia (quinine and occurrence of hypoglycaemia. Hypoglycaemia concurred with severity features, disruption of glucose infusion and transfusion. Careful glucose monitoring should be targeted to these complications where resources are limited.

    The aim of this study was to assess the correlation of inflammatory cytokines levels in tears with severity of dry eye disease in a cohort of patients with depression. Tear fluid samples were collected from 32 patients with depression treated with antidepressants, and 34 healthy subjects. Cytokines were assessed by ELISA. All the subjects completed the Beck Depression Inventory and performed the ophthalmic examination, including dry eye tests. The tear fluid levels of IL-6, IL-17 and TNF-α in depressive patients were higher than in controls. The clinical severity of dry eye disease correlated significantly with the IL-17 and TNF-α levels. Our results suggest a crucial role of inflammatory cytokines, especially IL-17 and TNF-α, in the development of severe dry eye disease in patients with depression. Clarification of the role pro-inflammatory cytokines in the pathogenesis of ocular findings in depressive patients may be useful in establishing immunotherapeutic strategies for this disease.

    Primary prevention of stroke and transient ischemic attack (TIA) is important to reduce the burden of these conditions; however, prescribing of prevention drugs is suboptimal. We aimed to identify individual clinical and demographic characteristics associated with potential missed opportunities for prevention therapy with lipid-lowering, anticoagulant, or antihypertensive drugs before stroke/TIA. We analyzed anonymized electronic primary care records from a UK primary care database that covers 561 family practices. Patients with first-ever stroke/TIA, ≥18 years, with diagnosis between January 1, 2009, and December 31, 2013, were included. Missed opportunities for prevention were defined as people with clinical indications for lipid-lowering, anticoagulant, or antihypertensive drugs but not prescribed these drugs before their stroke/TIA. Mixed-effect logistic regression models evaluated the relationship between missed opportunities and individual clinical/demographic characteristics. The inclusion criteria were met by 29 043 people with stroke/TIA. Patients with coronary heart disease, chronic kidney disease, peripheral arterial disease, or diabetes mellitus were at less risk of a missed opportunity for prescription of lipid-lowering and antihypertensive drugs. However, patients with a 10-year cardiovascular disease risk ≥20% but without these diagnoses had increased risk of having a missed opportunity for prescription of lipid-lowering drugs or antihypertensive drugs. Women were less likely to be prescribed anticoagulants but more likely to be prescribed antihypertensive drugs. The elderly (≥85 years of age) were less likely to be prescribed all 3 prevention drugs, compared with people aged 75 to 79 years. Knowing the patient characteristics predictive of missed opportunities for stroke prevention may help primary care identify and appropriately manage these patients. Improving the management of these groups may reduce their risk and potentially prevent

    Full Text Available Pressing demands of economic competitiveness, the need for large-scale deployment, minimizing the need of human intervention, and experience from the past events and incidents at operating reactors have guided the evolution and innovations in reactor technologies. Indian innovative reactor ‘AHWR’ is a pressure-tube type natural circulation based boiling water reactor that is designed to meet such requirements, which essentially reflect the needs of next generation reactors. The reactor employs various passive features to prevent and mitigate accidental conditions, like a slightly negative void reactivity coefficient, passive poison injection to scram the reactor in event of failure of the wired shutdown systems, a large elevated pool of water as a heat sink inside the containment, passive decay heat removal based on natural circulation and passive valves, passive ECC injection, etc. It is designed to meet the fundamental safety requirements of safe shutdown, safe decay heat removal and confinement of activity with no impact in public domain, and hence, no need for emergency planning under all conceivable scenarios. This paper examines the role of the various passive safety systems in prevention and mitigation of severe plant conditions that may arise in event of multiple failures. For the purpose of demonstration of the effectiveness of its passive features, postulated scenarios on the lines of three major severe accidents in the history of nuclear power reactors are considered, namely; the Three Mile Island (TMI, Chernobyl and Fukushima accidents. Severe plant conditions along the lines of these scenarios are postulated to the extent conceivable in the reactor under consideration and analyzed using best estimate system thermal-hydraulics code RELAP5/Mod3.2. It is found that the various passive systems incorporated enable the reactor to tolerate the postulated accident conditions without causing severe plant conditions and core degradation.

    Oxygen therapy might increase damaged tissue oxygenation, turn on the aerobic pathway, and save neurons from death and could improve clinical outcome of the patients with stroke and head trauma. Hyperbaric oxygen therapy is accompanied by some unfavorable effects. Results of normobaric oxygen therapy on clinical outcomes of patients with stroke were controversial up till now.  This study was therefore designed to evaluate effects of normobaric hyperoxia on clinical outcomes of patients with severe acute stroke. A total of 52 consecutive patients with stroke who meet the inclusion criteria of the study were entered into this randomized controlled clinical trial. The patients in the case group underwent oxygen therapy with Venturi mask for first 12 hours of admission. The patients were examined for neurologic defects at the time of discharge and after six months using both Barthel and modified Rankin Scale (mRS) neurologic disability scoring systems. There was no significant sex difference between the two groups (P=0.5). There was no statistically significant difference between ischemic-hemorrhagic stroke constitutions of two groups (P=0.2). There were no significant difference in Barthel index scores of both groups at the time of discharge as well as the follow-up examination (P=0.7) According to the mRS scoring system, there was no difference between the patients of both groups at the time of admission (P= 0.8), however after treatment there was a significant difference between mRS scores of the treated group compared to the controls (P=0.04). According to the results of this study, normobaric oxygen therapy in the first 12 hours of accident could improve long time outcome of the patients with either ischemic or hemorrhagic stroke.

    Insomnia has been linked to suicidal ideas and suicide death in cross-sectional and longitudinal population-based studies. A link between insomnia and suicide has not been previously examined in the setting of a clinical trial. Herein we describe the relationship between insomnia and suicidal thinking during the course of a clinical trial for depression with insomnia. Sixty patients aged 41.5±12.5 years (2/3 women) with major depressive episode and symptoms of insomnia received open-label fluoxetine for 9 weeks and also received blinded, randomized eszopiclone 3mg or placebo at bedtime after the first week of fluoxetine. Insomnia symptoms were assessed with the Insomnia Severity Index (ISI), and suicidal ideation was assessed with The Scale for Suicide Ideation (SSI). Depression symptoms were assessed with the depressed mood item and the anhedonia item from the Hamilton Rating Scale for Depression-24 (HRSD24), as well as a sum score for all non-sleep and non-suicide items from the HRSD (HRSD20). Measurements were taken at baseline and weeks 1, 2, 4, 6, and 8. SSI was examined by generalized linear mixed models for repeated measures as the outcome of interest for all 60 participants with ISI and various mood symptoms as independent variables, with adjustment for age, gender, treatment assignment, and baseline SSI. Higher levels of insomnia corresponded to significantly greater intensity of suicidal thinking (pmodel, the ISI remained an independent predictor of suicidal thinking. The results support the concept that insomnia may be a useful indicator for suicidal ideation and now extend this idea into clinical trials. Insomnia remains an independent indicator of suicidal ideation, even taking into account the core symptoms of depression such as depressed mood and anhedonia. The complaint of insomnia during a depression clinical trial might indicate that more direct questioning about suicide is warranted.

    Seborrheic dermatitis (SD) is a chronic and relapsing disease and topical therapy may be associated with failure, particularly in severe disease. Itraconazole has been suggested as an effective treatment for severe SD. Previous studies have been open clinical trials with variable results. The aim of this study was to determine the efficacy of oral itraconazole in the treatment of patients with moderate to severe SD. Sixty-eight patients with moderate to severe SD were randomly assigned to the itraconazole (n = 35) or placebo (n = 33) groups. The trial was undertaken in Razi Hospital, Tehran. An internet-generated table was used to allocate treatments. Patients and investigator were blinded to treatments. Itraconazole 200 mg/daily or placebo was prescribed for 1 week and then for the first 2 days of every month for the following 3 months. Patients were followed for 4 months and the Seborrheic Dermatitis Area Severity Index (SDASI) was measured on nine anatomical sites. Fifty-seven patients (29 in the itraconazole group and 28 in the placebo group) completed the study. Statistically significant improvement was observed in SDASI of both itraconazole and placebo groups (p = 0.000) but the itraconazole group showed significantly higher efficacy compared with placebo (p = 0.023). We observed clinical improvements of 93.8, 87.5, and 93.1% at the end of 2 weeks, 1 month, and 4 months, respectively, in the itraconazole group, and 82.1, 64.3, and 53.6% in the placebo group. Furthermore, recurrence rate in the itraconazole group was significantly lower than in the placebo group (p = 0.003). No blood test abnormality was seen in any patient. Itraconazole is not only an effective and safe therapy for controlling exacerbations of SD but may also be used as maintenance therapy to prevent disease recurrence.

    The paper deals with the justification and description of clinical and organizational approaches to preventing cardiovascular diseases (CVD) in the primary health care system (PHCS) under the present conditions of health care modernization in Russia. It formulates the basic directions of systematic measures in integration strategies for the prevention of noncommunicable diseases (mainly CVD) at a federal level, in which practical measures are presented to improve a system for the early detection of high-risk individuals and to carry out measures for risk factor correction in PHCS, i.e. to implement high-risk strategies, including clinical and organizational approaches to reconstituting the medical prevention infrastructure in PHCS. This is favored by the new normative documents adopted by the Ministry of Health of Russia on the follow-up and prophylactic medical examinations of the adult population. The paper substantiates the objective need for such examinations and characterizes the main clinical and organizational approaches promoted in medical examinations, which is aimed at introducing the current science-based and economically expedient methods in the real practice of PHCS for the early identifications of atherosclerosis-induced major CVDs and, what is particularly important, a risk for their development. Prophylactic counseling as a compulsory component is first being introduced in medical examination procedures. The key clinical and organizational principle of effective CVD prevention in public health is the implementation of the relationship and continuity of preventive measures, which becomes realistic with the adoption of new regulations of clinical examinations, prophylactic medical examinations, and follow-ups. The improvement of CVD prevention is associated not only with the introduction of organizational innovation changes, but also with the need to create a prevention ideology in physicians at all levels. It is emphasized that a comprehensive

    To present clinical information relevant to acute respiratory distress syndrome (ARDS) and its appearance in chiropractic acute care practice. The National Library of Medicine MEDLINE database was used, along with the bibliographies of selected articles and textbooks commonly found in chiropractic college libraries and bookstores. Clinical studies from the English literature were selected if they pertained to incidence, clinical relevancy, or the association of ARDS with commonly-seen diagnoses in chiropractic neuromusculoskeletal or orthopedic practice. All relevant studies identified by the search were evaluated based on information pertinent to chiropractic management of acute care patients. ARDS is a pulmonary distress syndrome with a high mortality rate. Recognizable indications for the possible development of ARDS include chest pain, head injury, and thoracic spine pain with or without trauma. Clinical evaluation, radiographic findings, and laboratory findings are presented to assist practitioners in identifying this disease process of multiple etiology. A study of the basic pathophysiologic processes that occur in the formation of ARDS is presented to help practitioners gain clinical appreciation. Strategies for preventing respiratory distress in chiropractic patients are also presented and include use of the postural position and the clinical maxim of "slow, deep breathing despite pain" to lessen incident rates of subjects at risk. Although ARDS may not be prevalent in chiropractic practice, it is important for physicians to be aware of the clinical basics (including its pathophysiology), its medical significance, and the preventive strategies that may be used to minimize its occurrence. This basic understanding will further advance knowledge of this disease complex.

    To compare the efficacy of an oxidized, regenerated cellulose adhesion barrier (Interceed; Ethicon, Somerville, NJ) combined with an intrauterine device (IUD) versus an IUD alone for preventing adhesion recurrence following hysteroscopic adhesiolysis for moderate to severe intrauterine adhesions (IUAs). Retrospective case series (Canadian Task Force classification III). Tertiary care teaching hospital. Patients undergoing treatment for moderate to severe IUAs. The severity of IUA was determined based on the American Fertility Society scoring system (mild, moderate, or severe). All cases of hysteroscopic adhesiolysis were reviewed. Seventy-six women with moderate to severe IUAs treated between March 2009 and August 2015 were included. After hysteroscopic adhesiolysis, 35 patients were treated with an IUD alone (group 1), and 41 patients were treated with Interceed plus an IUD (group 2). A second hysteroscopy was performed in all cases three months after the initial hysteroscopy and both groups achieved significant reduction in adhesion scores and grade, especially in group 2 (scores, p < .001; grade, p = .039). Compared with group 1, menstruation dysfunction, pregnancy rate, and live birth rate in group 2 improved with no statistical difference (menstruation improvement, p = .764; pregnancy rate, p = .310; live birth rate, p = .068). However, an adhesion-free uterine cavity was regained significantly owing to the fewer operations in group 2 compared with group 1 (median, 3 vs 4; p = .001). The interval from initial hysteroscopy to conception was significantly shorter in group 2 (median, 12 months vs 51 months; p < .001). For moderate to severe IUAs, Interceed combined with an IUD may be an alternative approach for reducing adhesion recurrence after hysteroscopic adhesiolysis. Copyright © 2016 AAGL.

    Background: Contrast induced nephropathy (CIN) is a serious but rare complication following contrast based procedures. Sodium bicarbonate (NaHCO{sub 3}) has been postulated to prevent CIN by various mechanisms. However, the outcomes following sodium bicarbonate administration to prevent CIN have been inconsistent. Methods: A meta-analysis of published randomized clinical trials to determine if the administration of sodium bicarbonate is superior to sodium chloride among patients with chronic renal failure undergoing catheterization and interventional procedures in preventing CIN was performed. Results: Data were combined across seven published clinical trials consisting of 1734 patients. There were no significant differences in the baseline characteristics between the NaHCO{sub 3} and NaCl groups except patients in the bicarbonate group were heavier (P = 0.04). The odds ratio (OR) for the development of contrast nephropathy for NaHCO{sub 3} versus NaCl was 0.33 (95% confidence interval [CI] 0.16-0.69; P = 0.003). Heterogeneity and publication bias were detectable with P-values 0.01 and 0.0005 respectively. There was no difference between the NaHCO{sub 3} group and the NaCl group in the occurrence of death [OR 0.6; 95% CI (0.26-1.41); P = 0.24], congestive heart failure [OR 0.85; 95% CI (0.32-2.24); P = 0.74] and the requirement for renal replacement therapy [OR 0.56; 95% CI (0.22-1.41); P = 0.22]. Conclusion: This meta-analysis demonstrates that based on currently available randomized trials, the administration of NaHCO{sub 3} is superior to the administration of NaCl alone in the prevention of CIN among patients with moderate to severe chronic kidney disease. However, further controlled clinical trials are needed due to significant study heterogeneity and publication bias.

    To evaluate the efficacy and safety of evaluation,treatment and follow-up of Kawasaki coronary artery disease based on the clinical severity classification. This study evaluated 52 patients admitted to the Children's Hospital of Fudan University between July 2005 and December 2013 who were diagnosed with Kawasaki Disease with coronary artery disease.Inclusion criteria were a disease course of more than two months, initial echocardiography showing severity of grade IV and above, and confirmation of disease severity by angiography. Of those studies, 44 were male and eight were female, aged 6 to 142 (average 41) months. Treatment was planned according to protocols in "Suggestions for Management of Kawasaki Coronary Artery Disease" with follow-up. Those patients with grade IV and above confirmed by angiogram were given oral low-dose asprin and warfarin, and those with grade Vb were given coronary artery bypass grafting (CABG) after comprehensive evaluation. Analysis was carried out for diagnosis, treatment, complications, and results of follow-up. (1) Satisfied images were shown by the angiography of all 52 cases. Forty five patients (86%) had giant aneurysm or multiple aneurysms, with thrombosis found in 10 of 45 patients (22%). Coronary artery lesions occurred in 138 coronary branches, and more common in left anterior descending branch (47 branches, with incidence 34%) and right coronary artery (48 branches, with incidence 35%). There were no complications during or after angiography. (2) After angiography, 49 patients remained at grade IV or above, and three improved to grade III. Ultimately, clinical severities of coronary artery disease included three patients at grade III, 31 patients at grade IV, nine patients at grade Va, and nine patients at grade Vb. (3) Thirty-eight patients were properly using aspirin and warfarin, and two patients with severely elevated international normalized ratio (INR) levels presented with knee joint and gastric hemorrhage, both of

    The ability of pharmacotherapies to prevent relapse and maintain efficacy with long-term treatment in psychiatric conditions is important. To assess lisdexamfetamine dimesylate maintenance of efficacy in adults with moderate to severe binge-eating disorder. A multinational, phase 3, double-blind, placebo-controlled, randomized withdrawal study including 418 participants was conducted at 49 clinical research study sites from January 27, 2014, to April 8, 2015. Eligible adults met DSM-IV-R binge-eating disorder criteria and had moderate to severe binge eating disorder (≥3 binge-eating days per week for 14 days before open-label baseline; Clinical Global Impressions-Severity [CGI-S] scores ≥4 [moderate severity] at screening and open-label baseline). Following a 12-week, open-label phase (dose optimization, 4 weeks [lisdexamfetamine dimesylate, 50 or 70 mg]; dose maintenance, 8 weeks), lisdexamfetamine responders (≤1 binge eating day per week for 4 consecutive weeks and CGI-S scores ≤2 at week 12) were randomized to placebo or continued lisdexamfetamine during a 26-week, double-blind, randomized withdrawal phase. Lisdexamfetamine administration. The primary outcome variable, time to relapse (≥2 binge-eating days per week for 2 consecutive weeks and ≥2-point CGI-S score increases from randomized withdrawal baseline), was analyzed using a log-rank test (primary analysis); the analysis was stratified for dichotomized 4-week cessation status. Safety assessments included treatment-emergent adverse events. Of the 418 participants enrolled in the open-label phase of the study, 411 (358 [87.1%] women; mean [SD] age, 38.3 [10.4] years) were included in the safety analysis set. Of 275 randomized lisdexamfetamine responders (placebo, n = 138; lisdexamfetamine, n = 137), the observed proportions of participants meeting relapse criteria were 3.7% (5 of 136) for lisdexamfetamine and 32.1% (42 of 131) for placebo. Lisdexamfetamine demonstrated superiority over

    Full Text Available Objectives: To describe the microbiological profile and clinical outcomes of diabetic foot ulcers of inpatients of a tertiary university hospital, at Ceara, Brazil. Methods: We conducted a retrospective analysis of medical charts data of all diabetic inpatients of the Endocrine and Diabetes Unit of Walter Cantídio University Hospital (Federal University of Ceará, admitted from January, 2006 to June, 2007 for severe foot ulcers (minimum of grade 2 of Wagner`s classification, which were refractory to ambulatory treatment. Clinical data from each patient were recorded (sex, age, diabetes duration, and comorbidities as well as microbiological characteristics of foot ulcers and surgical (amputations material. Results: We identified 17 diabetic patients, all type 2, aged 58.11 ± 10.8 years and 12.4 ± 8.4 years of disease, 58.8% male. Of ulcers, 41.1% were grade 2; 35.2% grade 3; 11.7% grade 4 and 11.7% grade 5 of Wagner; 64.7% with less than 3 months of evolution. Debridement was performed in 82.3% of patients and amputation in 47%; osteomyelitis was identified in 47% of cases. All patients started empiric antibiotic therapy, where ciprofloxacin/metronidazole was the most used scheme (76.5%. Cultures were negative in 12.5% of the patients. In the positive ones, the most prevalent bacterial pathogens detected in the culture materials were: S. aureus (57.1%; S. viridans (28.7%; P. aeruginosas (28.7%; M. morganii (28.7%. The majority (75% of isolated S. aureus were methicillin-resistant, but were sensitive to vacomicin. Conclusion: We observed the presence of polymicrobial flora with a large number of multiresistant pathogens and high prevalence of osteomyelitis and amputations in diabetic patients with severe ulcers, neuropathy and peripheral vascular disease.

    The number of obese pediatric patients requiring anesthesia is rapidly increasing. Although fentanyl is a commonly used narcotic during surgery, there are no pharmacokinetic (PK) data available for optimal dosing of fentanyl in adolescents with clinically severe obesity. An institutional review board-approved exploratory pilot study was conducted in six adolescents aged 14-19 years undergoing bariatric surgery. Mean total body weight (TBW) and mean BMI were 137.4 ± 14.3 kg and 49.6 ± 6.4 kg/m 2 (99.5th BMI percentile), respectively. Fentanyl was administered intravenously for intraoperative analgesia based on ideal body weight per standard of care. PK blood samples were drawn over a 24-h post-dose period. Fentanyl PK parameters were calculated by non-compartmental analysis. Mean fentanyl AUC 0-∞ was 1.5 ± 0.5 h·ng/mL. Systemic clearance of fentanyl was 1522 ± 310 mL/min and 11.2 ± 2.6 mL/min·kg TBW. Volume of distribution was 635 ± 282 L and 4.7 ± 2.1 L/kg TBW. While absolute clearance was increased, absolute volume of distribution was comparable to previously established adult values. These results suggest that fentanyl clearance is enhanced in adolescents with clinically severe obesity while volume of distribution is comparable to previously published studies.

    The Surviving Sepsis Campaign promotes the use of norepinephrine as the first-line inotropic support for patients presenting with severe sepsis or septic shock in cases of persistent hypotension, despite adequate fluid resuscitation. However, there is little published evidence on how much noradrenaline is administered to such patients when admitted to the intensive care unit (ICU). The authors report the clinical management of this group of patients, with a special focus on the total amount and duration of norepinephrine infusion required. A chart review of the admission records of an ICU in Hong Kong was carried out in 2013. A total of 5000 patients were screened by their diagnosis of severe sepsis or septic shock (in the admissions book) between 1 January 2011 and 31 December 2013. A total of 150 of these were identified and 100 included in the study after simultaneous in-depth reviews of their case notes by two of the investigators. The analysis covers those with severe sepsis or septic shock who required ICU admission for further care. Clinical management and outcomes were analysed. 100 patients (median age 61.6; M/F ratio 2:1) met the inclusion criteria. The mean ICU stay was 13.4 days (range=1-371). 14 patients (14%) died in the ICU, with a 28-day mortality rate of 22%. The mean period of mechanical ventilation was 6.1 days (range=0-137). 91.5% (n=43) of patients had been operated on immediately before admission to the ICU, and the majority of these operations had been of the emergency type (97.7%, n=43). The mean total volumes of crystalloid and colloid administered were 3420ml and 478ml, respectively. The mean wean-off period for norepinephrine infusion was 4234minutes (70.5hours). All patients were prescribed norepinephrine for persistent hypotension despite adequate fluid resuscitation, and the mean total amount administered was 87,211mg. Final multiple linear and logistic regression analysis showed different clinical outcomes associated with different

    Cardiovascular disease (CVD) in the ageing is a major public health problem worldwide. The nature of most CVD is subclinical with pathological processes that can span over years. Use of preventive measures could be an appropriate approach to prevailing over CVD in the ageing, and herbal medicine is one of the promising preventive approaches and is currently of interest among medical societies. In the evidence-based era, herbal medicine is, however, often underestimated and approached with skepticism, mainly due to the paucity of scientific evidence. Properly designed clinical trials on herbal medicine for prevention of CVD in a geriatric population are thus of importance and of clinical value. To review ethical issues and discuss considerations when such research is proposed. Four ethical issues, including the scientific validity of research, risk-benefit assessments, subject selection and vulnerability, and informed consent, are structured and extensively discussed in this article. Ethical core considerations of prevention research of CVD on herbal medicine involve particular attention on the scientific validity of research, risk-benefit assessments, subject selection and vulnerability, and informed consent. These issues and considerations are keys, although they must be adapted to an individual research setting in which a clinical study is proposed. Copyright © 2015 Elsevier GmbH. All rights reserved.

    To explore youth clinic midwives role in cervical cancer prevention and their attitude to HPV vaccination. Individual interviews with 13 midwives working at youth clinics in Sweden. The interviews were recorded, transcribed, and analysed by qualitative content analysis. Three themes were identified in the qualitative content analysis: "Cervical cancer prevention not a prioritised area", "Ambivalence to the HPV vaccine", and "Gender and socioeconomic controversies". Few midwives talked spontaneously about cervical cancer prevention. The responsibility for providing information about HPV vaccination was considered as primarily that of school health nurses and parents. Midwives were positive about the HPV vaccination, but recognised certain risks, such as its potential negative impact on cervical cancer screening and increased sexual risk taking. The midwives expressed concerns with medical risks, such as side effects and unknown long-term effects of the HPV vaccine. The midwives in the study had ethical concerns that boys were not included in the program and not all families had the financial resources to vaccinate their children. Thus, weak socioeconomic groups might be excluded. The midwives considered cervical cancer prevention as important, but did not integrate information on the HPV vaccine into their routine work, mainly because young people visiting youth clinics had had their sexual debut and they were concerned about the medical risks and that the vaccine was too expensive.

    The teeth most commonly affected by trauma are the maxillary central incisors. The most frequent types of traumatic dental injuries to permanent teeth are enamel fractures, enamel and dentine fractures, and enamel and dentine fractures with pulp involvement. This article describes three clinical cases with different levels of traumatized maxillary incisors and several cosmetic approaches for recovery of the esthetics and the masticatory function, as well as the social/psychological aspects of treatment. All cases involved young adult men. The three clinical cases involve dentin and enamel fractures, dentin and enamel fractures with pulp exposure, and dentin and enamel fractures with pulp exposure associated with root fracture. The cosmetic treatments used to resolve fractures were direct composite resin by layering technique, indirect all-ceramic restorations (laminate veneer and ceramic crowns over the teeth), and immediate implant after extraction followed by immediate loading (ceramic abutments with ceramic crown over implant). In all three cases, excellent functional and esthetic results were achieved by use of these treatment modalities. The patients were very satisfied with the results. © 2011 John Wiley & Sons A/S.

  4. Levels of Social Sharing and Clinical Implications for Severe Social Withdrawal in Patients with Personality Disorders

    2017-12-01

    Full Text Available Social sharing capacities have attracted attention from a number of fields of social cognition and have been variously defined and analyzed in numerous studies. Social sharing consists in the subjective awareness that aspects of the self’s experience are held in common with other individuals. The definition of social sharing must take a variety of elements into consideration: the motivational element, the contents of the social sharing experience, the emotional responses it evokes, the behavioral outcomes, and finally, the circumstances and the skills which enable social sharing. The primary objective of this study is to explore some of the diverse forms of human social sharing and to classify them according to levels of complexity. We identify four different types of social sharing, categorized according to the nature of the content being shared and the complexity of the mindreading skills required. The second objective of this study is to consider possible applications of this graded model of social sharing experience in clinical settings. Specifically, this model may support the development of graded, focused clinical interventions for patients with personality disorders characterized by severe social withdrawal.

    Full Text Available In this study, we evaluated the effect of proton pump inhibitors (PPIs on in vitro antimicrobial activity of tigecycline against several species of clinical pathogens. Clinical non-duplicate isolates of Acinetobacter baumannii, Staphylococcus aureus, Enterococcus faecalis and three species of Enterobacteriaceae (Escherichia coli, Klebsiella pneumonia and Enterobacter cloacae were collected from a tertiary hospital and their MICs of tigecycline alone and in combination with PPIs (omeprazole, lansoprazole and pantoprazole were determined. With one randomly selected isolate of each bacterial species, an in vitro time-kill study was performed for the confirmation of the effect of PPIs on tigecycline activity. The MIC changes after PPIs addition correlated with the PPIs concentrations in the test media. Compared with tigecycline alone, the addition of 5 mg/L PPIs could increase the MICs of tigecycline by 0 to 2-fold and the addition of 50 mg/L PPIs could increase the MICs of tigecycline by 4 to >128-fold. The time-kill study confirmed that the addition of PPIs could affect the in vitro activity of tigecycline. Even at low concentration (5 mg/L of omeprazole and pantoprazole, antagonistic effect could be observed in E. cloacae and E. faecalis strains. We conclude that In vitro activity of tigecycline can be influenced by the presence of PPIs in a concentration-dependent manner.

    X-linked severe combined immunodeficiency (X-SCID) is a rare, life-threatening immune disorder, caused by mutations of the gene for the γ-chain (γc) of the interleukin-2 receptor, IL2RG. We analyzed the clinical, immunologic, and molecular characteristics of children with X-SCID, attempting to improve the diagnosis and treatment of X-SCID in China. X-SCID was suspected in male infants with recurrent or persistent infections. Eleven male infants from ten unrelated Chinese families were included. The IL2RG gene was amplified and sequenced, followed by mutation analysis in these children and their female relatives. X-linked short tandem repeat (X-STR) typing was done to define the maternal lymphocyte engraftment. The 11 children exhibited recurrent infections and 10 of them had lymphopenia. B cells were present in all patients, T cells were markedly reduced in 10, and NK cells were markedly reduced in 9. Nine IL2RG gene mutations were identified in the 11 children, with 5 novel mutations. One patient was found to have the maternal lymphocyte engraftment. The clinical presentations and immunologic characteristics of the X-SCID patients were accordingly quite uniform despite the heterogeneity of mutations locating almost in the entire γc gene.

    The study explored relationships between preferences for and experiences of clinical decision making (CDM) with service use among persons with severe mental illness. Data from a prospective observational study in six European countries were examined. Associations of baseline staff-rated (N=213) and patient-rated (N=588) preferred and experienced decision making with service use were examined at baseline by using binomial regressions and at 12-month follow-up by using multilevel models. A preference by patients and staff for active patient involvement in decision making, rather than shared or passive decision making, was associated with longer hospital admissions and higher costs at baseline and with increases in admissions over 12 months (p=.043). Low patient-rated satisfaction with an experienced clinical decision was also related to increased costs over the study period (p=.005). A preference for shared decision making may reduce health care costs by reducing inpatient admissions. Patient satisfaction with decisions was a predictor of costs, and clinicians should maximize patient satisfaction with CDM.

    Sleep disruption is common among hematopoietic cell transplant (HCT) recipients, with over 50% of recipients experiencing sleep disruption pre-transplant, with up to 82% of patients experiencing moderate to severe sleep disruption during hospitalization for transplant and up to 43% after transplant. These rates of sleep disruption are substantially higher than what we see in the general population. Although sleep disruption can be distressing to patients and contribute to diminished quality of life, it is rarely discussed during clinical visits. The goal of the current review is to draw attention to sleep disruption and disorders (ie, insomnia, obstructive sleep apnea, restless legs syndrome) as a clinical problem in HCT in order to facilitate patient education, intervention, and research. We identified 35 observational studies published in the past decade that examined sleep disruption or disorders in HCT. Most studies utilized a single item measure of sleep, had small sample size, and included heterogeneous samples of patients. Six studies of the effects of psychosocial and exercise interventions on sleep in HCT have reported no significant improvements. These results highlight the need for rigorous observational and interventional studies of sleep disruption and disorders in HCT recipients..

    Full Text Available AbstractObjective: To describe the clinical characteristics, lung function, radiological findings, and the inflammatory cell profile in induced sputum in children and adolescents with severe therapy-resistant asthma (STRA treated at a referral center in southern Brazil.Methods: We retrospectively analyzed children and adolescents (3-18 years of age with uncontrolled STRA treated with high-dose inhaled corticosteroids and long-acting β2 agonists. We prospectively collected data on disease control, lung function, skin test reactivity to allergens, the inflammatory cell profile in induced sputum, chest CT findings, and esophageal pH monitoring results.Results: We analyzed 21 patients (mean age, 9.2 ± 2.98 years. Of those, 18 (86% were atopic. Most had uncontrolled asthma and near-normal baseline lung function. In 4 and 7, induced sputum was found to be eosinophilic and neutrophilic, respectively; the inflammatory cell profile in induced sputum having changed in 67% of those in whom induced sputum analysis was repeated. Of the 8 patients receiving treatment with omalizumab (an anti-IgE antibody, 7 (87.5% showed significant improvement in quality of life, as well as significant reductions in the numbers of exacerbations and hospitalizations.Conclusions: Children with STRA present with near-normal lung function and a variable airway inflammatory pattern during clinical follow-up, showing a significant clinical response to omalizumab. In children, STRA differs from that seen in adults, further studies being required in order to gain a better understanding of the disease mechanisms.

    Full Text Available BACKGROUND: Massive wasp stings have been greatly underestimated and have not been systematically studied. The aim of this study was to identify the clinical features and treatment strategies of severe wasp stings. METHODS AND FINDINGS: A multicenter retrospective study was undertaken in 35 hospitals and medical centers including 12 tertiary care hospitals and 23 secondary care hospitals in the Hubei Province, China. The detailed clinical data of 1091 hospitalized wasp sting patients were investigated. Over three-fourths (76.9% of the cases had 10 or more stings and the in-hospital mortality of patients was 5.1%. Forty-eight patients died of organ injury following toxic reactions to the stings, whereas six died from anaphylactic shock. The in-hospital mortality in patients with >10 stings was higher than that of ≤10 stings (5.2% vs. 1.0%, p = 0.02. Acute kidney injury (AKI was seen in 21.0% patients and most patients required blood purification therapy. Rhabdomyolysis was seen in 24.1% patients, hemolysis in 19.2% patients, liver injury in 30.1% patients, and coagulopathy in 22.5% patients. Regression analysis revealed that high creatinine level, shock, oliguria, and anemia were risk factors for death. Blood purification therapy was beneficial for patients with ≥20 stings and delayed hospital admission of patients (≥4 hours after sting. CONCLUSIONS: In China, most patients with multiple wasp stings presented with toxic reactions and multiple organ dysfunction caused by the venom rather than an anaphylactic reaction. AKI is the prominent clinical manifestation of wasp stings with toxic reaction. High creatinine levels, shock, oliguria, and anemia were risk factors for death.

    Full Text Available Suicide is reaching epidemic proportions, with over 44,000 deaths by suicide in the US, and 800,000 worldwide in 2015. This, despite research and development of evidence-based interventions that target suicidal behavior directly. Suicide prevention efforts need a comprehensive approach, and research must lead to effective implementation across public and mental health systems. A 10-year systematic review of evidence-based findings in suicide prevention summarized the areas necessary for translating research into practice. These include risk assessment, means restriction, evidence-based treatments, population screening combined with chain of care, monitoring, and follow-up. In this article, we review how suicide prevention research informs implementation in clinical settings where those most at risk present for care. Evidence-based and best practices address the fluctuating nature of suicide risk, which requires ongoing risk assessment, direct intervention and monitoring. In the US, the National Action Alliance for Suicide Prevention has put forth the Zero Suicide (ZS Model, a framework to coordinate a multilevel approach to implementing evidence-based practices. We present the Assess, Intervene and Monitor for Suicide Prevention model (AIM-SP as a guide for implementation of ZS evidence-based and best practices in clinical settings. Ten basic steps for clinical management model will be described and illustrated through case vignette. These steps are designed to be easily incorporated into standard clinical practice to enhance suicide risk assessment, brief interventions to increase safety and teach coping strategies and to improve ongoing contact and monitoring of high-risk individuals during transitions in care and high risk periods.

    Full Text Available Abstract Background Report a nationwide epidemic of Shiga toxin-producing E. coli (STEC O103:H25 causing hemolytic uremic syndrome (D+HUS in children. Methods Description of clinical presentation, complications and outcome in a nationwide outbreak. Results Ten children (median age 4.3 years developed HUS during the outbreak. One of these was presumed to be a part of the outbreak without microbiological proof. Eight of the patients were oligoanuric and in need of dialysis. Median need for dialysis was 15 days; one girl did not regain renal function and received a kidney transplant. Four patients had seizures and/or reduced consciousness. Cerebral oedema and herniation caused the death of a 4-year-old boy. Two patients developed necrosis of colon with perforation and one of them developed non-autoimmune diabetes. Conclusion This outbreak of STEC was characterized by a high incidence of HUS among the infected children, and many developed severe renal disease and extrarenal complications. A likely explanation is that the O103:H25 (eae and stx2-positive strain was highly pathogen, and we suggest that this serotype should be looked for in patients with HUS caused by STEC, especially in severe forms or outbreaks.

    The prevalence of molar incisor hypomineralization (MIH) varies considerably around the world; however, few studies have examined MIH in South American countries. To evaluate the prevalence, severity, and clinical consequences of MIH in Brazilian children residing in rural and urban areas of the municipality of Botelhos, Minas Gerais, Brazil. Children aged 6 to 12 years (n = 918) with all four-first permanent molars erupted had these teeth evaluated according to the European Academy of Paediatric Dentistry (EAPD) criteria. The examinations were conducted by two previously trained examiners, and the dental impact caused by MIH was evaluated with the Decayed, Missing and Filled Teeth (DMFT) index (WHO). Molar incisor hypomineralization was present in 19.8% of the 918 children, with a higher prevalence in rural areas. The majority of the defects presented were demarcated opacities without post-eruptive structural loss, which has been considered as mild defects. Children with MIH had higher DMFT values. Despite the high prevalence of MIH, the severity of the defects was mild. The results indicate a positive association between MIH and the presence of dental caries. © 2010 The Authors.

    ABSTRACT Shedding of microparticles (MPs) is a consequence of apoptotic cell death and cellular activation. Low levels of circulating MPs in blood help maintain homeostasis, whereas increased MP generation is linked to many pathological conditions. Herein, we investigated the role of MPs in dengue virus (DENV) infection. Infection of various susceptible cells by DENV led to apoptotic death and MP release. These MPs harbored a viral envelope protein and a nonstructural protein 1 (NS1) on their surfaces. Ex vivo analysis of clinical specimens from patients with infections of different degrees of severity at multiple time points revealed that MPs generated from erythrocytes and platelets are two major MP populations in the circulation of DENV-infected patients. Elevated levels of red blood cell-derived MPs (RMPs) directly correlated with DENV disease severity, whereas a significant decrease in platelet-derived MPs was associated with a bleeding tendency. Removal by mononuclear cells of complement-opsonized NS1–anti-NS1 immune complexes bound to erythrocytes via complement receptor type 1 triggered MP shedding in vitro, a process that could explain the increased levels of RMPs in severe dengue. These findings point to the multiple roles of MPs in dengue pathogenesis. They offer a potential novel biomarker candidate capable of differentiating dengue fever from the more serious dengue hemorrhagic fever. IMPORTANCE Dengue is the most important mosquito-transmitted viral disease in the world. No vaccines or specific treatments are available. Rapid diagnosis and immediate treatment are the keys to achieve a positive outcome. Dengue virus (DENV) infection, like some other medical conditions, changes the level and composition of microparticles (MPs), tiny bag-like structures which are normally present at low levels in the blood of healthy individuals. This study investigated how MPs in culture and patients' blood are changed in response to DENV infection. Infection of cells

    Robust evidence for the efficacy of rituximab monotherapy in pemphigus is lacking. The effects of rituximab on T-regulatory cells (Tregs) in pemphigus have not been studied. The primary objective was to assess the efficacy of rituximab monotherapy in severe pemphigus vulgaris. The secondary objectives were to assess whether counts of different subsets of Tregs in the peripheral blood correlate with baseline clinical severity and whether clinical response in severe pemphigus is associated with an alteration in the Treg count. Eighteen eligible subjects with severe pemphigus vulgaris were recruited and were treated with 1 g of intravenous rituximab on days 0 and 15. Efficacy was assessed in terms of disease control, time to disease control, complete remission off therapy, and relapse. Flow cytometric analysis of CD4+CD25+FoxP3, IL-10-secreting Tr1, and TGF-β secreting Th3 regulatory cells was performed. Clinical evaluation and flow cytometric analysis of Tregs was performed periodically until follow-up at 26 weeks. Rituximab monotherapy was able to induce complete remission in all but 5 (68.75%) patients and was well tolerated. No direct relationship between clinical severity and CD4+CD25+FoxP3 cell counts was found. There were inverse correlations between serially measured values of the cutaneous and mucosal Autoimmune Bullous Skin Disorder Intensity Score (ABSIS) and Th3 cell count. Rituximab is a safe and effective monotherapy option for severe pemphigus. As the immunological findings were somewhat different from those observed in other autoimmune conditions treated with rituximab, further studies are required to substantiate the findings of our study in pemphigus patients. © 2016 S.

    Clinical features of attention deficit hyperactivity disorder can be frequently observed in cases with bipolar disorders and associated with greater severity of bipolar disorders. Although designed as a screening tool for attention deficit hyperactivity disorder, the Wender Utah Rating Scale could, given its factorial structure, be useful in investigating the early history of impulsive, inattentive or mood-related symptoms among patients with bipolar disorders. We rated the Wender Utah Rating Scale in 276 adult bipolar disorder cases and 228 healthy controls and tested its factorial structure and any associations with bipolar disorder phenomenology. We confirmed a three-factor structure for the Wender Utah Rating Scale (' impulsivity/temper', ' inattentiveness' and ' mood/self-esteem'). Cases and controls differed significantly on Wender Utah Rating Scale total score and sub-scale scores ( p-values bipolar disorder cases versus 5% of controls were classified as ' WURS positive' (odds ratio = 5.21 [2.73-9.95]). In bipolar disorders, higher Wender Utah Rating Scale score was associated with earlier age at onset, severity of suicidal behaviors and polysubstance misuse; multivariate analyses, controlling for age and gender, confirmed the associations with age at onset ( p = 0.001) and alcohol and substance misuse ( p = 0.001). Adults with bipolar disorders who reported higher levels of childhood symptoms on the Wender Utah Rating Scale presented a more severe expression of bipolar disorders in terms of age at onset and comorbidity. The Wender Utah Rating Scale could be employed to screen for attention deficit hyperactivity disorder but also for ' at-risk behaviors' in adult bipolar disorder cases and possibly for prodromal signs of early onset in high-risk subjects.

    Objective: To determine the levels of coagulation and inflammatory factors in women with moderate and severe ovarian endometriosis so as to investigate the possible role of coagulation and inflammatory factors in the pathogenesis, diagnosis and treatment of this disease. Methods: From June 2015 and June 2017, clinical data of 366 patients with pathologically diagnosed moderate and severe ovarian endometriosis (case group) and 244 patients with pathologically diagnosed benign ovarian cysts (control group) in Women's Hospital of Zhejiang University School of Medicine were retrospectively analyzed. The levels of coagulation indicators, inflammatory factors and serum tumor markers were measured. Then, the values of these indicators in diagnosis of endometriosis were analyzed. Results: (1) The levels of plasma prothrombin time (PT) and thrombin time (TT) in patients with ovarian endometriosis [median: 12.8 s (range: 12.4-13.2 s) and 15.5 s (range: 15.1-15.9 s), respectively] were significantly shorter than those with benign ovarian cysts [median: 13.0 s (range: 12.5-13.4 s) and 15.7 s (range: 15.3-16.1 s), respectively; all P endometriosis were significantly higher than those with benign ovarian cysts [median: 2.8 g/L (range: 2.6-3.2 g/L) and 0.6 mg/L (range: 0.4-1.2 mg/L), respectively; P =0.000]. Moreover, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio [PLR; median: 2.3 (range: 1.8-3.1) and 144 (range: 113-179), respectively] in patients with ovarian endometriosis were significantly higher than those with benign ovarian cysts [median: 2.1 (range: 1.6-2.8) and 128 (range: 104-165), respectively; P endometriosis, the levels of PT were significantly shorter in stage Ⅳ endometriosis than that in stage Ⅲ endometriosis ( P endometriosis were significantly higher than those in patients with stage Ⅲ endometriosis ( P endometriosis, and the detection of coagulation and inflammatory factors may be have important clinical significance for the

    The co-circulation of 4 DENV serotypes in geographically expanding area, has resulted in increasing occurrence of DENV co-infections. However, studies assessing the clinical impact of DENV co-infections have been scarce and have involved small number of patients. This study explores the impact of DENV co-infection on clinical manifestations and laboratory parameters. This retrospective study involved consecutive hospitalized patients with non-structural protein 1 (NS1) antigen positivity during an outbreak (Jan to April 2014). Multiplex RT-PCR was performed directly on NS1 positive serum samples to detect and determine the DENV serotypes. All PCR-positive serum samples were inoculated onto C6/36 cells. Multiplex PCR was repeated on the supernatant of the first blind passage of the serum-infected cells. Random samples of supernatant from the first passage of C6/36 infected cells were subjected to whole genome sequencing. Clinical and laboratory variables were compared between patients with and without DENV co-infections. Of the 290 NS1 positive serum samples, 280 were PCR positive for DENV. Medical notes of 262 patients were available for analysis. All 4 DENV serotypes were identified. Of the 262 patients, forty patients (15.3 %) had DENV co-infections: DENV-1/DENV-2(85 %), DENV-1/DENV-3 (12.5 %) and DENV-2/DENV-3 (2.5 %). Another 222 patients (84.7 %) were infected with single DENV serotype (mono-infection), with DENV- 1 (76.6 %) and DENV- 2 (19.8 %) predominating. Secondary dengue infections occurred in 31.3 % patients. Whole genome sequences of random samples representing DENV-1 and DENV-2 showed heterogeneity amongst the DENVs. Multivariate analysis revealed that pleural effusion and the presence of warning signs were significantly higher in the co-infected group, both in the overall and subgroup analysis. Diarrhoea was negatively associated with co-infection. Additionally, DENV-2 co-infected patients had higher frequency of patients with severe thrombocytopenia

    Accurate documentation of disease severity is a prerequisite for clinical research and the practice of evidence-based medicine. The quantification of skin diseases such as psoriasis currently relies heavily on clinical scores. Although these clinical scoring methods are well established and very useful in quantifying disease severity, they require an extensive clinical experience and carry a risk of subjectivity. We explore the opportunity to use in vivo near-infrared (NIR) spectra as an objective and noninvasive method for local disease severity assessment in 31 psoriasis patients in whom selected plaques were scored clinically. A partial least squares (PLS) regression model was used to analyze and predict the severity scores on the NIR spectra of psoriatic and uninvolved skin. The correlation between predicted and clinically assigned scores was R=0.94 (RMSE=0.96), suggesting that in vivo NIR provides accurate clinical quantification of psoriatic plaques. Hence, NIR may be a practical solution to clinical severity assessment of psoriasis, providing a continuous, linear, numerical value of severity.

    The strikingly higher prevalence of migraine in females compared with males is one of the hallmarks of migraine. A large global body of evidence exists on the sex differences in the prevalence of migraine with female to male ratios ranging from 2:1 to 3:1 and peaking in midlife. Some data are available on sex differences in associated symptoms, headache-related disability and impairment, and healthcare resource utilization in migraine. Few data are available on corresponding sex differences in probable migraine (PM) and other severe headache (ie, nonmigraine-spectrum severe headache). Gaining a clear understanding of sex differences in a range of severe headache disorders may help differentiate the range of headache types. Herein, we compare sexes on prevalence and a range of clinical variables for migraine, PM, and other severe headache in a large sample from the US population. This study analyzed data from the 2004 American Migraine Prevalence and Prevention Study. Total and demographic-stratified sex-specific, prevalence estimates of headache subtypes (migraine, PM, and other severe headache) are reported. Log-binomial models are used to calculate sex-specific adjusted prevalence ratios and 95% confidence intervals for each across demographic strata. A smoothed sex prevalence ratio (female to male) figure is presented for migraine and PM. One hundred sixty-two thousand seven hundred fifty-six individuals aged 12 and older responded to the 2004 American Migraine Prevalence and Prevention Study survey (64.9% response rate). Twenty-eight thousand two hundred sixty-one (17.4%) reported "severe headache" in the preceding year (23.5% of females and 10.6% of males), 11.8% met International Classification of Headache Disorders-2 criteria for migraine (17.3% of females and 5.7% of males), 4.6% met criteria for PM (5.3% of females and 3.9% of males), and 1.0% were categorized with other severe headache (0.9% of females and 1.0% of males). Sex differences were observed in

    To examine the impact of rurality on 30-day preventable readmission, and the illness severity and risk of mortality for 30-day preventable readmissions. We analyzed heart failure Medicare beneficiaries who received home health services for postacute care after hospital discharge in 2009. The study was a cross-sectional design with the unit of analysis as the home health episode for postacute care. Data sources included the following: Medicare Beneficiary Summary File, Medicare Provider Analysis Review, Outcome Assessment Information Set, Home Health Agency Research Identifiable File, and Area Health Resources File. The dependent variables were 30-day preventable readmission, and the extreme/major level of illness severity and of risk of mortality for a 30-day preventable readmission. The key independent variable was rurality defined as remote rural, adjacent rural, and micropolitan areas, with urban areas in the reference group. Home health beneficiaries in remote rural areas had 27% lower 30-day preventable readmission than those in urban areas. Home health beneficiaries in adjacent rural areas were 33% less likely to have high illness severity at readmission due to a preventable condition than those in urban areas. Geographical location affects preventable readmission and illness severity of preventable readmission. Patients' geographic location along with patients' risk factors should be taken into consideration in the risk adjustment model for the financial incentive program that penalizes home health agencies with high preventable readmissions. © 2015 National Rural Health Association.

    Full Text Available Thyroid associated ophthalmopathy (TAO is an autoimmune inflammatory disorder which disfigures appearance, threatens vision, and results in a pronounced loss of quality of life. The diversity and ethnic difference of the disease manifestations have made it difficult to tailor therapies for each patient. Few studies have analyzed its characteristics in Chinese populations. We therefore enrolled 354 patients with moderate-to-severe TAO from February 2015 to July 2016. A single ophthalmologist consistently performed detailed ophthalmic examinations. Orbital computed tomography or magnetic resonance imaging scans were performed to verify enlarged extraocular muscles. Multiple linear regression was used to analyze the association between sex, age, smoking, family history of thyroid diseases, degree of proptosis and disease severity. The mean age of males (46.56±11.08 years was significantly higher than that of females (41.39±years, with a female-to-male ratio of 1.09. The females and males between 31~40 and 41~50 years, respectively, had the highest incidence of TAO. 81.48% of the patients suffered hyperthyroidism. TAO was diagnosed either after (47.17% or simultaneously with thyroid dysfunction (27.68%. Proptosis (91.24%, eyelid retraction (83.33%, together with eyelid swelling (79.38% and extraocular muscle enlargement (75.42%, were the most common clinical sign. 19.77% of patients manifested lower eyelid retraction. The mean values of exophthalmos and asymmetry on proptosis were 19.94±3.45mm and 2.18±2.06mm, respectively in males, 18.58±3.31mm and 1.61±1.53mm, respectively in females. The severity of disease was significantly associated with male, older age, smoking, family history of thyroid diseases and degree of proptosis. We found several differences in Chinese compared with White. The female-to-male ratio and mean value of exophthalmos were significantly lower than the data of White. Inferior and superior rectus became the most common

    Full Text Available Background: Omalizumab is the first and yet the only biopreparation for asthma which combines high efficiency and high cost. The clinical-economic expediency of using omalizumab in asthmatic children has not been previously studied in Russia.Objective: Our aim was to evaluate the clinical and economic expediency of using omalizumab as additive treatment (to basic or supporting therapy in children with severe uncontrolled atopic asthma under the Russian economic conditions.Methods: We conducted a mathematical simulation of asthma treatment in children with an increased frequency of hospitalization (9 times per year with an average monthly omalizumab requirement of 558 mg. The model is based on the Markov chain. The model includes direct and non-direct costs. The planning horizons were 2 and 5 years. We analyzed the efficiency and utility of the costs and their influence on the budget. The stability of received data is proven by sensitivity analyzis.Results: Over a 5-year planning horizon the cost of an additional year of quality life (due to using omalizumab was 1,259,185 roubles, while the “society’s solvency” is 1 341 308 roubles (cost utility analizis. It takes 39,820 rubles to prevent one hospitalization with omalizumab over a 5-year planning horizon (cost efficiency analizis, which is comparable to the cost of hospitalization (43,141 rubles. Total costs for treating 100 children with asthma, 7 of which would be treated with omalizumab, were equal to the amount of money which is enough to treat 105 children without omalizumab (analysis of budgetary influence.Conclusion: The analyses of cost efficiency and utility have shown that the strategy of using omalizumab together with standard treatment is economically expedient. Budgetary influence analysis has not detected a significant burden on the budget.

    The American Society of Clinical Oncology (ASCO) has a policy and set of procedures for endorsing recent clinical practice guidelines that have been developed by other professional organizations. The Cancer Care Ontario (CCO) Guideline on Follow-up Care, Surveillance Protocol, and Secondary Prevention Measures for Survivors of Colorectal Cancer was reviewed by ASCO for methodologic rigor and considered for endorsement. The ASCO Panel concurred with the CCO recommendations and recommended endorsement, with the addition of several qualifying statements. Surveillance should be guided by presumed risk of recurrence and functional status of the patient (important within the first 2 to 4 years). Medical history, physical examination, and carcinoembryonic antigen testing should be performed every 3 to 6 months for 5 years. Patients at higher risk of recurrence should be considered for testing in the more frequent end of the range. A computed tomography scan (abdominal and chest) is recommended annually for 3 years, in most cases. Positron emission tomography scans should not be used for surveillance outside of a clinical trial. A surveillance colonoscopy should be performed 1 year after the initial surgery and then every 5 years, dictated by the findings of the previous one. If a colonoscopy was not preformed before diagnosis, it should be done after completion of adjuvant therapy (before 1 year). Secondary prevention (maintaining a healthy body weight and active lifestyle) is recommended. If a patient is not a candidate for surgery or systemic therapy because of severe comorbid conditions, surveillance tests should not be performed. A treatment plan from the specialist should have clear directions on appropriate follow-up by a nonspecialist.

    Congenital syphilis (CS) is a public health burden in both developing and developed countries. We report two cases of CS in premature neonates with severe clinical manifestations; Patient 1 (gestational age 31 weeks, birth weight 1423 g) had disseminated idiopathic coagulation (DIC) while Patient 2 (gestational age 34 weeks and 6 days, birth weight 2299 g) had refractory syphilitic meningitis. Their mothers were single and had neither received antenatal care nor undergone syphilis screening. Both neonates were delivered via an emergency cesarean section and had birth asphyxia and transient tachypnea of newborn. Physical examination revealed massive hepatosplenomegaly. Laboratory testing of maternal and neonatal blood showed increased rapid plasma reagin (RPR) titer and positive Treponema pallidum hemagglutination assay. Diagnosis of CS was further supported by a positive IgM fluorescent treponemal antibody absorption test and large amounts of T. pallidum spirochetes detected in the placenta. Each neonate was initially treated with ampicillin and cefotaxime for early bacterial sepsis/meningitis that coexisted with CS. Patient 1 received fresh frozen plasma and antithrombin III to treat DIC. Patient 2 experienced a relapse of CS during initial antibiotic treatment, necessitating parenteral penicillin G. Treatment was effective in both neonates, as shown by reductions in RPR. Monitoring of growth and neurological development through to age 4 showed no evidence of apparent delay or complications. Without adequate antenatal care and maternal screening tests for infection, CS is difficult for non-specialists to diagnose at birth, because the clinical manifestations are similar to those of neonatal sepsis and meningitis. Ampicillin was insufficient for treating CS and penicillin G was necessary.

    Noise induced hearing loss is a slowly developing hearing impairment, caused by occupational exposure to excessive noise levels, constitutes a lesion of the auditory analyzer and clinically manifested as chronic bilateral sensorineural hearing loss. Currently, there is not a treatment that provide a cure of sensorineural hearing loss. Regular, individually tailored treatment should be directed to the pathogenic mechanisms and specific clinical symptoms of hearing loss, as well as the prevention of complications. We recommend using non-drug therapies that can improve blood flow in labyrinth, tissue and cellular metabolism.

    Full Text Available Abstract Background Theories of behavior change indicate that an analysis of barriers to change is helpful when trying to influence professional practice. The aim of this study was to assess the perceived barriers to practice change by eliciting nurses' opinions with regard to barriers to, and facilitators of, implementation of a Fall Prevention clinical practice guideline in five acute care hospitals in Singapore. Methods Nurses were surveyed to identify their perceptions regarding barriers to implementation of clinical practice guidelines in their practice setting. The validated questionnaire, 'Barriers and facilitators assessment instrument', was administered to nurses (n = 1830 working in the medical, surgical, geriatric units, at five acute care hospitals in Singapore. Results An 80.2% response rate was achieved. The greatest barriers to implementation of clinical practice guidelines reported included: knowledge and motivation, availability of support staff, access to facilities, health status of patients, and, education of staff and patients. Conclusion Numerous barriers to the use of the Fall Prevention Clinical Practice Guideline have been identified. This study has laid the foundation for further research into implementation of clinical practice guidelines in Singapore by identifying barriers to change in acute care settings.

    A randomized clinical trial compared two materials used to prevent epidural scarring after microdiscectomy. To determine whether ADCON-L Gel (ALG) or Preclude Spinal Membrane (PSM) was more effective in preventing scarring, reducing pain, and improving quality of life postoperatively. Postdiscectomy syndrome may result from epidural scarring. Various materials have been used in attempts to prevent this problem, but none have provided optimal results. Previous laboratory and clinical studies have found ALG and PSM to be effective, but none compared the two materials. Thirty-one patients undergoing primary microdiscectomy were randomly assigned to receive either ALG or PSM. Postoperatively, patients were evaluated by magnetic resonance imaging (MRI), with contrast, for volume and rostral-caudal extent of scar tissue and nerve root involvement. Back and leg pain and quality of life were assessed by neurologic examinations and standardized patient surveys. Findings at any reoperations were recorded. Results in the PSM (n = 18) and ALG (n = 13) groups were compared statistically. No operative or postoperative complications occurred. Two patients in each group required reoperation. MRI at 6 months showed no, mild or mild-moderate scarring in most patients, with no significant differences between the ALG and PSM groups in scar volume and extent or nerve root involvement. Neurologic examinations and patient surveys showed substantial reductions in pain over time in both groups but no significant differences between groups. PSM was easy to see and remove at reoperation. PSM and ALG are equally effective in preventing epidural scarring associated with postdiscectomy syndrome.

    Obesity impacts the U.S. military by affecting the health and readiness of active duty service members and their families. Preventing Obesity in Military Communities (POMC) is a comprehensive research program within Patient Centered Medical Homes (PCMHs) in three Military Training Facilities. This paper describes three pilot randomized controlled trials that target critical high risk periods for unhealthy weight gain from birth to young adulthood: (1) pregnancy and early infancy (POMC-Mother-Baby), (2) adolescence (POMC-Adolescent), and (3) the first tour of duty after boot camp (POMC-Early Career). Each study employs a two-group randomized treatment or prevention program with follow up. POMC offers a unique opportunity to bring together research and clinical expertise in obesity prevention to develop state-of-the-art programs within PCMHs in Military Training Facilities. This research builds on existing infrastructure that is expected to have immediate clinical benefits to DoD and far-reaching potential for ongoing collaborative work. POMC may offer an economical approach for widespread obesity prevention, from conception to young adulthood, in the U.S. military as well as in civilian communities. PMID:25648176

    Leading scientific and organizational prerequisites for the feasibility of clinical examination of the entire child population of the Russian Federation to the dentist is, above all, the high prevalence and intensity of dental diseases in children of all ages. As a result of many years of research and follow-up of children of preschool and school age we have proved the need to distinguish a group of children with zero activity of dental caries. The referring criteria are determined according to the results of comprehensive clinical and laboratory examination in order to determine the degree of risk of dental caries and individual caries resistance. The age-specific risk group is settled by "Stop caries" software. In order to optimize the preventive activities children are divided in 5 groups for routine preventive dental care. Unfortunately the efforts of modern dental services aimed at eliminating the consequences of caries process by filling cavities. Individualized preventive approach will increase the effectiveness of preventive measures and save public funds allocated in the amount of compulsory health insurance for pediatric dentistry.

    Aims This study characterized the population pharmacokinetics (PK) of imatinib in patients with severe pulmonary arterial hypertension (PAH), investigated drug–drug interactions (DDI) among imatinib, sildenafil and bosentan, and evaluated their clinical implications. Methods Plasma concentrations of imatinib, bosentan and sildenafil were collected in a phase III study and were used to characterize the PK of imatinib in this population. DDIs among the three drugs were quantified using a linear mixed model and log-transformed drug concentrations. Results The population mean estimates of apparent clearance (CL/F) and volume (V/F) were 10.8 l h–1 (95% CI 9.2, 12.4 l h–1) and 267 l (95% CI 208, 326 l), respectively. It was estimated that sildenafil concentrations increased, on average, by 64% (95% CI 32%, 103%) and bosentan concentrations by 51% (95% CI 12%, 104%), in the presence of imatinib. Despite increased concentrations of co-medications, treatment differences between imatinib and placebo for change in 6 min walk distance and pulmonary vascular resistance were relatively constant across the entire concentration range for sildenafil and bosentan. Overall, higher concentrations of imatinib and bosentan were not associated with increasing liver enzymes (serum glutamic oxaloacetic transaminases [SGOT]/serum glutamic-pyruvic transaminase [SGPT]). Conclusions Population PKs of imatinib in patients with severe PAH were found comparable with those of patients with chronic myeloid leukemia. Imatinib was found effective regardless of the co-medications and showed intrinsic efficacy beyond merely elevating the concentrations of the co-medications due to DDIs. There was no evidence of increased risk of liver toxicity upon co-administration with bosentan. PMID:25581063

    Full Text Available BACKGROUND Recent advances in pathophysiology and therapeutic measures suggest that patients suffering from acute pancreatitis (AP should undergo an early evaluation and treatment in Internal Medicine wards. Severe AP, usually associated with pancreatic necrosis and peripancreatic fluid collections, may be frequently complicated by distant organ(s involvement. RESULTS The dreadful multi-organ failure may occur as an early event (during the first week of the disease or in association with the infection of pancreatic necrosis in a later stage. So, during the clinical outcome, physicians may be compelled to counteract cardio-circulatory, pulmonary, renal, hepatic, haematological and hydro-electrolytic complex derangements. Arterial hypotension and shock may be consequence of hypovolemia and/or hearth failure or septic shock syndrome. Pleural effusions are frequent in the early phase of the disease as well as pulmonary densifications and renal insufficiency. Urinary, pulmonary, and biliary infections may intervene during all phases of the disease whereas pancreatic necrosis and fluid collections infections are more frequent after the second week of hospitalization. Prognostic evaluation should be obtained by simple and precise scoring system such as the modified Marshall score and CT-scan severity index. CONCLUSIONS Treatment must be initiated as soon as possible with special focusing on fluid and nutritional supplementation, pain control, cardio-respiratory support, antiproteases and antibiotics. Invasive procedures such as endoscopic sphincterotomy in biliary AP with cholangitis and/or obstruction and percutaneous drainage should be utilized in specific cases. Surgical necrosectomy is mandatory in patients with documented infection of pancreatic necrosis.

  18. Clinical review: Brain-body temperature differences in adults with severe traumatic brain injury

    2013-01-01

    Surrogate or 'proxy' measures of brain temperature are used in the routine management of patients with brain damage. The prevailing view is that the brain is 'hotter' than the body. The polarity and magnitude of temperature differences between brain and body, however, remains unclear after severe traumatic brain injury (TBI). The focus of this systematic review is on the adult patient admitted to intensive/neurocritical care with a diagnosis of severe TBI (Glasgow Coma Scale score of less than 8). The review considered studies that measured brain temperature and core body temperature. Articles published in English from the years 1980 to 2012 were searched in databases, CINAHL, PubMed, Scopus, Web of Science, Science Direct, Ovid SP, Mednar and ProQuest Dissertations & Theses Database. For the review, publications of randomised controlled trials, non-randomised controlled trials, before and after studies, cohort studies, case-control studies and descriptive studies were considered for inclusion. Of 2,391 records identified via the search strategies, 37 were retrieved for detailed examination (including two via hand searching). Fifteen were reviewed and assessed for methodological quality. Eleven studies were included in the systematic review providing 15 brain-core body temperature comparisons. The direction of mean brain-body temperature differences was positive (brain higher than body temperature) and negative (brain lower than body temperature). Hypothermia is associated with large brain-body temperature differences. Brain temperature cannot be predicted reliably from core body temperature. Concurrent monitoring of brain and body temperature is recommended in patients where risk of temperature-related neuronal damage is a cause for clinical concern and when deliberate induction of below-normal body temperature is instituted.

    To evaluate the clinical efficacy of intradermal injection of methylene blue for treatment of moderate to severe acute thoracic herpes zoster and prevention of postherpetica neuralgia in elderly patients. Sixty-four elderly patients with herpes zoster were randomized to receive a 10-day course of intradermal injection of methylene blue and lidocaine plus oral valaciclovir (group A, 32 cases) and intradermal injection of lidocaine plus oral valaciclovir (group B).Herpes evaluation index, pain rating index, incidence of postherpetic neuralgia, and comprehensive therapeutic effect were compared between the two groups at 11, 30 and 60 days after the treatment. The baseline characteristics were comparable between the two groups (all P>0.05). Compared with that in group B, the time for no new blister formation, blister incrustation and decrustation, and pain relief was significantly shortened in group A (Pmethylene blue can effectively shorten the disease course, reduce the pain intensity and prevent the development of postherpetic neuralgia in elderly patients with herpes zoster.

    Full Text Available Severe burn injuries may result in gastrointestinal paralysis, and barrier dysfunction due to gut ischemia and lowered vagus excitability. In this study we investigate whether electroacupuncture (EA at Zusanli (ST36 could prevent severe scalds-induced gut ischemia, paralysis, and barrier dysfunction and whether the protective role of EA at ST36 is related to the vagus nerve. 35% burn area rats were divided into six groups: (a EAN: EA nonchannel acupoints followed by scald injury; (b EA: EA at ST36 after scald injury; (c VGX/EA: vagotomy (VGX before EA at ST36 and scald injury; (d VGX/EAN: VGX before EAN and scald injury; (e atropine/EA: applying atropine before scald injury and then EA at ST36; (f atropine/EAN: applying atropine before scald injury and then EA at nonchannel acupoints. EA at the Zusanli point significantly promoted the intestinal impelling ratio and increased the amount of mucosal blood flow after scald injury. The plasma diamine oxidase (DAO and intestinal permeability decreased significantly after scald injury in the EA group compared with others. However, EA after atropine injection or cervical vagotomy failed to improve intestinal motility and mucosa blood flow suggesting that the mechanism of EA may be related to the activation of the cholinergic nerve pathway.

    Most epidemiologic studies involving severe granulomatosis with polyangiitis (SGPA) patients have investigated populations from the northern hemisphere, whereas few studies have been conducted in South America. None of the South American studies have differentiated between localized GPA and SGPA. The present study was designed to describe a cohort of Argentinean patients who were diagnosed with SGPA and to compare this cohort with previously well-described cohorts. We performed a retrospective study that included 37 consecutive SGPA patients who were seen at 2 tertiary centers in Buenos Aires. Nineteen patients (51.3%) were male, and 18 patients (49.7%) were female. The mean age at the onset of symptoms was 48.5 ± 12.01 years. Antineutrophil cytoplasmic antibody (ANCA) was detected in 34 patients (91.89%): 32 patients (86.48%) had a cytoplasmic staining pattern, whereas 2 patients (5.40%) had a perinuclear pattern. Three patients were ANCA-negative. Twenty-four patients (64%) achieved remission, and 7 patients (19%) had response as defined by at least 50% reduction in the disease activity score. Nineteen relapses were observed in 12 patients, and 2 of the relapses were fatal. Overall, there were 14 deaths (37.83%). The present series demonstrated that Argentinean patients have similar demographics, clinical manifestations, and outcomes as the cohorts from the northern hemisphere. There was less granulomatous organ involvement (ear/nose/throat, lung granulomas) in the present cohort compared with other series.

    Severe forms of psoriasis including erythrodermic or pustular psoriasis, which require a more aggressive therapeutic approach such as phototherapy or systemic therapies, are rarely seen. Systemic toxicity and long-term safety of these agents are serious concerns in children. We report our experience on the efficacy and safety of cyclosporine A treatment in 22 patients of childhood psoriasis. We retrospectively analyzed the records of all patients less than 18 years of age treated with systemic cyclosporine A therapy at our clinic between January 2000 and March 2009. Demographic features as well as other relevant data including previous therapies, the dosage and duration of cyclosporine A therapy, response to treatment and side effects were retrieved from the patients' records. A total of 22 children were treated with systemic cyclosporine A therapy. Seventeen patients were found to be excellent responders. The mean therapeutic dosage of cyclosporine A was 3.47 ± 0.62 mg/kg/day. The mean duration of cyclosporine A therapy was 5.68 ± 3.29 months. The median time to total clearance of the lesions was 4.0 weeks. We conclude that cyclosporine A therapy is equally effective and safe in pediatric psoriasis patients as in adults.

    HIV prevention during pregnancy and lactation is critical for both maternal and child health. Pregnancy provides a critical opportunity for clinicians to elicit women's vulnerabilities to HIV and offer HIV testing, treatment and referral and/or comprehensive HIV prevention options for the current pregnancy, the postpartum period and safer conception options for future pregnancies. In this commentary, we review the safety of oral pre-exposure prophylaxis with tenofovir/emtricitabine in pregnant and lactating women and suggest opportunities to identify pregnant and postpartum women at substantial risk of HIV. We then describe a clinical approach to caring for women who both choose and decline pre-exposure prophylaxis during pregnancy and postpartum, highlighting areas for future research. Evidence suggests that pre-exposure prophylaxis with tenofovir/emtricitabine is safe in pregnancy and lactation. Identifying women vulnerable to HIV and eligible for pre-exposure prophylaxis is challenging in light of the myriad of individual, community, and structural forces impacting HIV acquisition. Validated risk calculators exist for specific populations but have not been used to screen and offer HIV prevention methods. Partner testing and engagement of men living with HIV are additional means of reaching at-risk women. However, women's vulnerabilities to HIV change over time. Combining screening for HIV vulnerability with HIV and/or STI testing at standard intervals during pregnancy is a practical way to prompt providers to incorporate HIV screening and prevention counselling. We suggest using shared decision-making to offer women pre-exposure prophylaxis as one of multiple HIV prevention strategies during pregnancy and postpartum, facilitating open conversations about HIV vulnerabilities, preferences about HIV prevention strategies, and choosing a method that best meets the needs of each woman. Growing evidence suggests that pre-exposure prophylaxis with tenofovir

    The doctoral thesis is based on eight papers published in peer-reviewed journals and a review of the literature. The papers are published between 1997 and 2013 in cooperation with Sankt Elisabeth Hospital, Herlev Hospital, Glostrup Hospital, Rigshospitalet, Hvidovre Hospital, Amager Hospital, Copenhagen Trial Unit, and Institute of Preventive Medicine, Copenhagen. Groin injuries in sport are very common and in football they are among the most common and most time-consuming injuries. These injuries are treated very differently around the world. There is no consensus in the literature regarding definitions, examination methods, diagnosis or treatment and in general the level of evidence is very low. There is a need for identification of the painful anatomical structures, how to examine them and how to define clinical entities to develop effective treatment and prevention. The aim of these studies were: - To review the literature to create an overview of the ideas and the knowledge in order to plan future studies in this field. - Develop and test clinical examination techniques of the relevant tendons and muscles in the region. - Since no evidence-based diagnosis exist; to develop a set of clinical entities to identify the different groups of patients. - To test the effect of a dedicated exercise program developed for treatment of long-standing adductor-related groin pain in athletes in a randomised clinical trial comparing it to the treatment modalities used at that time. - To examine the long-term effect of the above mentioned training program for treatment of long-standing adductor-related groin pain. - To develop a training program for prevention of groin injuries in soccer and test it in a randomised clinical trial. - To describe the occurrence and presentation in clinical entities of groin injuries in male football and to examine the characteristics of these injuries. - Evaluate if radiological signs of femuro-acetabular impingement (FAI) or dysplasia affect the

    To investigate the effects of probiotics on blood glucose levels and clinical outcomes in patients suffering from severe craniocerebral trauma. A prospective randomized control study was conducted. Fifty-two severe craniocerebral trauma patients admitted to intensive care unit (ICU) were randomized into experimental or control group (each n=26). All patients received conventional treatment according to Guidelines for the Clinical Management of Traumatic Brain Injury and enteral nutrition within 24-48 hours after admission through nasogastric tube. In addition, the experimental group received 1×10(9) bacteria of viable probiotics (Golden Bifid, 3.5 g for 3 times per day) per day for 21 days. The fasting blood glucose levels were determined in the morning before intervention and on day 4, 8, 15, 21 after intervention. Amount of insulin used during hospitalization, Glasgow coma scale (GCS) scores, length of ICU stay, and 28-day mortality rate were studied. There was no difference in term of the blood glucose levels between two groups before intervention. On day 8 and 15 after intervention, significantly lower levels of fasting blood glucose were observed in the experimental group compared with those of the control group (8 days: 6.6±1.2 mmol/L vs. 8.0±2.7 mmol/L, t=-2.500, P=0.017; 15 days: 6.1±1.4 mmol/L vs. 7.2±2.2 mmol/L, t=-2.269, P=0.028). There were significantly less patients treated with insulin or shorter days of insulin therapy in experimental group than in control group [19.2% (5/26) vs. 46.2% (12/26), χ(2)=4.282, P=0.039; 1.6±0.9 vs. 4.3±3.1, t=-2.698, P=0.017]. The length of ICU stay was significantly shorter in the experimental group than that of control group (6.8±3.8 days vs. 10.7±7.3 days, t=-2.123, P=0.034). No significant differences were found about the GCS scores (before intervention: 6.3±1.0 vs. 6.4±1.0, t=-0.408, P=0.685; 21 days after intervention: 10.1±4.0 vs. 9.6±4.3, t=0.435, P=0.665) and 28-day mortality rate [11.5% (3/26) vs

    Severe malaria is a medical emergency associated with high mortality. Adequate treatment requires initial parenteral therapy for fast parasite clearance followed by longer acting oral antimalarial drugs for cure and prevention of recrudescence. In a randomized controlled clinical trial, we evaluated the 42-day parasitological outcomes of severe malaria treatment with intravenous artesunate (AS) or intravenous quinine (QNN) followed by oral artemisinin based combination therapy (ACT) in children living in a high malaria transmission setting in Eastern Uganda. We enrolled 300 participants and all were included in the intention to treat analysis. Baseline characteristics were similar across treatment arms. The median and interquartile range for number of days from baseline to parasite clearance was significantly lower among participants who received intravenous AS (2 (1-2) vs 3 (2-3), P malaria symptoms. In this high transmission setting, we observed adequate initial treatment outcomes followed by very high rates of malaria re-infection post severe malaria treatment. The impact of recurrent antimalarial treatment on the long term efficacy of antimalarial regimens needs to be investigated and surveillance mechanisms for resistance markers established since recurrent malaria infections are likely to be exposed to sub-therapeutic drug concentrations. More strategies for prevention of recurrent malaria infections in the most at risk populations are needed. The study was registered with the Pan African Clinical Trial Registry ( PACTR201110000321348 ).

  12. The prevention of diabetic foot ulceration: how biomechanical research informs clinical practice

    Directory of Open Access Journals (Sweden)

    Frank E. DiLiberto

    Full Text Available ABSTRACT Background Implementation of interprofessional clinical guidelines for the prevention of neuropathic diabetic foot ulceration has demonstrated positive effects regarding ulceration and amputation rates. Current foot care recommendations are primarily based on research regarding the prevention of ulcer recurrence and focused on reducing the magnitude of plantar stress (pressure overload. Yet, foot ulceration remains to be a prevalent and debilitating consequence of Diabetes Mellitus. There is limited evidence targeting the prevention of first-time ulceration, and there is a need to consider additional factors of plantar stress to supplement current guidelines. Objectives The first purpose of this article is to discuss the biomechanical theory underpinning diabetic foot ulcerations and illustrate how plantar tissue underloading may precede overloading and breakdown. The second purpose of this commentary is to discuss how advances in biomechanical foot modeling can inform clinical practice in the prevention of first-time ulceration. Discussion Research demonstrates that progressive weight-bearing activity programs to address the frequency of plantar stress and avoid underloading do not increase ulceration risk. Multi-segment foot modeling studies indicate that dynamic foot function of the midfoot and forefoot is compromised in people with diabetes. Emerging research demonstrates that implementation of foot-specific exercises may positively influence dynamic foot function and improve plantar stress in people with diabetes. Conclusion Continued work is needed to determine how to best design and integrate activity recommendations and foot-specific exercise programs into the current interprofessional paradigm for the prevention of first-time ulceration in people with Diabetes Mellitus.

    Plant-derived elements used for pharmacological applications constitute an increasing research field. Centella asiatica is widely used mainly as an extract (TECA). Triterpenic fractions, the primary constituents of Centella asiatica, produce a wide range of preventive and therapeutic effects. The modulation of collagen production and deposition in wound healing is of primary importance. TECA is also used to treat several microcirculatory problems, inflammatory skin conditions (leprosy, lupus, varicose ulcers, eczema, atopic dermatitis, psoriasis) and also intestinal problems, fever, amenorrhea and genitourinary conditions. Cognitive functions, anxiety and mental impairment may be also affected by TECA administration. New applications in neurology include nerve growth factor enhancement and applications in neurological degenerative conditions. Interaction with other products is also indicated in this document. The multiplicity of actions of TECA is associated to six important mechanisms, all inter-connected and modulating each other: 1) edema - and capillary filtration - control; 2) a strong antioxidant power, effective on several forms of oxidative stress associated to inflammation or infections and synergic with other antioxidant products; 3) an anti-inflammatory action; 4) a modulation of the collagen production avoiding slower scarring or faster, hyperthrophic scarring and cheloids; 5) a modulating action of local growth factors; 6) a modulation of angiogenesis. This "status" paper - resulting from an expert meeting held in Cobham, Surrey, indicates most of the therapeutic potential of TECA, still to be explored in further studies. The status paper constitutes the basis for a consensus document on TECA to be developed in the next future. This "status" paper opens a new window on an ancient but still partially unexplored product that may become an important value in prevention and treatment of several pre-clinical and risk conditions and in clinically significant

    Recently, the Quantitative Analysis of Normal Tissue Effect in the Clinic (QUANTEC) Group defined dose-volume constraints for the parotid glands to avoid severe xerostomia. The aim of this study was to determine if application of these QUANTEC criteria also protected against moderate-to-severe patient-rated xerostomia. The study population consisted of 307 head and neck cancer patients treated with primary (chemo)radiotherapy, either with 3D-CRT (56%) or with IMRT (44%). All patients participated in a standard follow-up program in which radiation-induced toxicity and quality of life were prospectively assessed. Patients who met the QUANTEC criteria were classified as low risk and otherwise as high risk. In total, 41% of the patients (treated with 3D-CRT and IMRT) were classified as low risk patients. In the group treated with 3D-CRT and IMRT, it was possible to meet the QUANTEC criteria in 47% and 32% of the patients, respectively. Sparing the parotid glands with IMRT was considerably more difficult in patients with lymph node metastases and in patients with nasopharyngeal and oropharyngeal tumours. Low risk patients reported significantly less moderate-to-severe xerostomia than high risk patients. However, the predicted risk of elderly patients and patients with pre-existing minor patient-rated xerostomia at baseline was > 20%, even when the QUANTEC criteria were met. Significantly lower rates of radiation-induced patient-rated xerostomia were found among low risk patients treated according to the QUANTEC criteria, but these criteria do not completely protect against xerostomia. Particularly in elderly patients and patients already suffering from minor xerostomia at baseline, the QUANTEC criteria do not sufficiently protect against persistent, moderate-to-severe patient-rated xerostomia.

    To determine the prevalence of clinically important traumatic brain injuries (TBIs) with severe injury mechanisms in children with minor blunt head trauma but with no other risk factors from the Pediatric Emergency Care Applied Research Network (PECARN) TBI prediction rules (defined as isolated severe injury mechanisms). Secondary analysis of a large prospective observational cohort study. Twenty-five emergency departments participating in the PECARN. Children with minor blunt head trauma and Glasgow Coma Scale scores of at least 14. Treating clinicians completed a structured data form that included injury mechanism (severity categories defined a priori). Clinically important TBIs were defined as intracranial injuries resulting in death, neurosurgical intervention, intubation for more than 24 hours, or hospital admission for at least 2 nights. We investigated the rate of clinically important TBIs in children with either severe injury mechanisms or isolated severe injury mechanisms. Of the 42,412 patients enrolled in the overall study, 42,099 (99%) had injury mechanisms recorded, and their data were included for analysis. Of all study patients, 5869 (14%) had severe injury mechanisms, and 3302 (8%) had isolated severe injury mechanisms. Overall, 367 children had clinically important TBIs (0.9%; 95% CI, 0.8%-1.0%). Of the 1327 children younger than 2 years with isolated severe injury mechanisms, 4 (0.3%; 95% CI, 0.1%-0.8%) had clinically important TBIs, as did 12 of the 1975 children 2 years or older (0.6%; 95% CI, 0.3%-1.1%). Children with isolated severe injury mechanisms are at low risk of clinically important TBI, and many do not require emergent neuroimaging.

    Full Text Available HMGCoA-inhibitors (statins lower plasma cholesterol through interference with the rate-limiting enzyme in the endogenous synthesis process. Since their introduction in the early 90’s, the clinical attitude towards cardiovascular (cv risk reduction has evolved from the attention to single risk factors to a more comprehensive global risk evaluation, and thus the indications of statins have broadened from the secondary prevention in hypercholesterolemic patients to include primary prevention in mildly and moderately hypercholesterolemic, or even normocholesterolemic patients, provided their global cv risk is considered high (typically, an estimated major cv event probability greater than 20%. Italian drug utilization data show that a small proportion of patients who could benefit from statins do actually receive them, contributing to the persistence of the clinical and economical burden of cv disease, the leading cause of mortality; since statins have proved effective, and cost-effective, in cv prevention, a more widespread use appears desirable, but requires high investments in pharmaceutical costs. This article defines a clinical profile of lovastatin, a statin with a solid efficacy and safety record only recently introduced into the Italian market despite it has been the first to become clinically available abroad. Among available statin formulations appropriate for target cholesterol reductions up to 30%, which apply to a significant proportion of statin therapy candidates, lovastatin 20 mg is marketed at the lowest price. Although the individual response to the different statins is highly unpredictable, determining a mandatory empirical molecule- and dose-finding strategy on the single patient, from the societal point of view the choice to start with lower cost molecules, among options that on average are equally-effective, may limit initial drug investment and dampen the impact of resource waste secondary to treatment interruptions and

  20. Clinical preventive services in Guatemala: a cross-sectional survey of internal medicine physicians.

    Full Text Available Guatemala is currently undergoing an epidemiologic transition. Preventive services are key to reducing the burden of non-communicable diseases, and smoking counseling and cessation are among the most cost-effective and wide-reaching strategies. Internal medicine physicians are fundamental to providing such services, and their knowledge is a cornerstone of non-communicable disease control.A national cross-sectional survey was conducted in 2011 to evaluate knowledge of clinical preventive services for non-communicable diseases. Interns, residents, and attending physicians of the internal medicine departments of all teaching hospitals in Guatemala completed a self-administered questionnaire. Participants' responses were contrasted with the Guatemalan Ministry of Health (MoH prevention guidelines and the US Preventive Services Task Force (USPSTF recommendations. Analysis compared knowledge of recommendations within and between hospitals.In response to simulated patient scenarios, all services were recommended by more than half of physicians regardless of MoH or USPSTF recommendations. Prioritization was adequate according to the MoH guidelines but not including other potentially effective services (e.g. colorectal cancer and lipid disorder screenings. With the exception of colorectal and prostate cancer screening, less frequently recommended by interns, there was no difference in recommendation rates by level.Guatemalan internal medicine physicians' knowledge on preventive services recommendations for non-communicable diseases is limited, and prioritization did not reflect cost-effectiveness. Based on these data we recommend that preventive medicine training be strengthened and development of evidence-based guidelines for low-middle income countries be a priority.

    Background/Aims It is unclear whether the risk factors associated with complicated diverticulitis in Asian and Western countries are the same. We evaluated the risk factors associated with severe diverticulitis (SD) in Korea and compared the clinical characteristics of diverticulitis according to location. Methods A retrospective review of 190 patients hospitalized with acute diverticulitis from January 2005 to June 2010 was conducted. SD was defined as one of the following: perforation, abscess, obstruction, sepsis, or peritonitis that required an urgent operation. Results Twenty-four patients (12.6%) were diagnosed with SD. SD was significantly associated with older age, a fever over 38℃, changes in bowel habits and a high visceral adipose tissue (VAT)/total adipose tissue (TAT) ratio. Multivariate analysis showed that the risk factors for developing SD were an age of 40 years or more (odds ratio [OR], 3.2; p=0.032), male gender (OR, 4.0; p=0.021) and left-sided diverticulitis (OR, 6.2; p=0.017). Right-sided diverticulitis (n=175, 92.1%) was significantly associated with younger ages, fewer changes in bowel habits, fewer comorbidities and non-SD. Conclusions This study suggests that the risk factors for developing SD in Korea, where right-sided diverticulitis is predominant, are the male gender, an age of more than 40 years old, and left-sided diverticulitis. Given that there are different risk factors for developing SD in Western countries, different strategies for the treatment of diverticulitis in the Korean population seem to be needed. PMID:22375175

    The Mahalapye district health management team (DHMT) conducts regular audits to evaluate the standard of services delivered to patients, one of which is the prevention of mother-to-child-transmission (PMTCT) programme. Xhosa clinic is one of the facilities in Mahalapye which provides a PMTCT programme. This audit aimed to identify gaps between the current PMTCT clinical practice in Xhosa clinic and the Botswana PMTCT national guidelines. This audit took place in Xhosa clinic in the urban village of Mahalapye, in the Central District of Botswana. This was a retrospective audit using PMTCT Xhosa clinic records of pregnant mothers and HIV-exposed babies seen from January 2013 to June 2013. One hundred and thirty-three pregnant women registered for antenatal care. Twenty-five (19%) knew their HIV-positive status as they had been tested before their pregnancy or had tested HIV positive at their first antenatal clinic visit. More than two-thirds of the 115 pregnant women (69%) were seen at a gestational age of between 14 and 28 weeks. About two-thirds of the pregnant women (67%) took antiretroviral drugs. Of the 44 HIV-exposed infants, 39 (89%) were HIV DNA PCR negative at 6 weeks. Thirty-two (73%) children were given cotrimoxazole prophylaxis between 6 and 8 weeks. The PMTCT programme service delivery was still suboptimal and could potentially increase the mother-to-child transmission of HIV. Daily monitoring mechanism to track those eligible could help to close the gap.

    Salivary dysfunction in Sjögren disease can lead to serious and costly oral health complications. Clinical practice guidelines for caries prevention in Sjögren disease were developed to improve quality and consistency of care. A national panel of experts devised clinical questions in a Population, Intervention, Comparison, Outcomes format and included use of fluoride, salivary stimulants, antimicrobial agents, and nonfluoride remineralizing agents. The panel conducted a systematic search of the literature according to pre-established parameters. At least 2 members extracted the data, and the panel rated the strength of the recommendations by using a variation of grading of recommendations, assessment, development, and evaluation. After a Delphi consensus panel was conducted, the experts finalized the recommendations, with a minimum of 75% agreement required. Final recommendations for patients with Sjögren disease with dry mouth were as follows: topical fluoride should be used in all patients (strong); although no study results link improved salivary flow to caries prevention, the oral health community generally accepts that increasing saliva may contribute to decreased caries incidence, so increasing saliva through gustatory, masticatory, or pharmaceutical stimulation may be considered (weak); chlorhexidine administered as varnish, gel, or rinse may be considered (weak); and nonfluoride remineralizing agents may be considered as an adjunct therapy (moderate). The incidence of caries in patients with Sjögren disease can be reduced with the use of topical fluoride and other preventive strategies. Copyright © 2016 American Dental Association.

    The design and execution of prevention trials for OA have methodological issues that are distinct from trials designed to impact prevalent disease. Disease definitions and their precise and sensitive measurement, identification of high-risk populations, the nature of the intervention (pharmaceutical, nutraceutical, behavioral) and its potential pleiotropic impacts on other organ systems are critical to consider. Because prevention trials may be prolonged, close attention to concomitant life changes and co-morbidities, adherence and participant retention in the trial is of primary importance, as is recognition of the potential for "preventive misconception" and "behavioral disinhibition" to affect the ability of the trial to show an effect of the intervention under study. None of these potential pitfalls precludes a successful and scientifically rigorous process and outcome. As technology improves the means to measure and predict the OA process and its clinical consequences, it will be increasingly possible to screen individuals for high-risk phenotypes, combining clinical factors with information from imaging, genetic, metabolic and other biomarkers and to impact this high-risk condition to avoid or delay OA both structurally and symptomatically.

    Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system. Neurological impairments are caused by axonal damage due to demyelination and neuroinflammation within the central nervous system. T cells mediate the neuroinflammation. The activation of T cells is induced by the release of adenosine triphosphate and involves purinergic receptors as well as pannexin (Panx) proteins. As Panx1 is expressed on T cells, we here propose that application of probenecid, a known Panx inhibitor, will prevent the onset of clinical symptoms in a mouse model of MS, the experimental autoimmune encephalomyelitis (EAE) model. EAE-induced mice received daily injections of probenecid. Disease scores, T cell numbers, and microglia activation were compared between experimental groups. Probenecid treatment resulted in lower disease scores as compared to EAE animals. Probenecid-treated animals also displayed fewer inflammatory lesions. Microglia activation was not altered by treatment. In conclusion, probenecid prevented the onset of EAE.

    Excess weight and menopause are two major factors increasing aging women's vulnerability to chronic diseases. However, social position and socioeconomic status have also been identified as major determinants influencing both health behaviors and the development of such diseases. This study focuses on the socioeconomic variations of behavioral risk factors of chronic diseases in aging women. By drawing on Bourdieu's sociocultural theory of practice, 40 semistructured interviews were conducted to investigate preventive health practices of clinically overweight, postmenopausal women from contrasting socioeconomic classes living in Canada. Findings emphasize class-based differences with respect to long-term health and preventive practices according to three major themes: priority to long-term time horizons, attention given to risk factors of diseases, and control over future health. Health care providers should strive to work in concert with all subgroups of women to better understand their values, worldviews, and needs to decrease health inequalities after menopause.

    The cancer stem cell model introduces new strategies for the prevention and treatment of cancers. In cancers that appear to follow the stem cell model, pathways such as Wnt, Notch and Hedgehog may be targeted with natural compounds such as curcumin or drugs to reduce the risk of initiation of new tumors. Disease progression of established tumors could also potentially be inhibited by targeting the tumorigenic stem cells alone, rather than aiming to reduce overall tumor size. These new approaches mandate a change in the design of clinical trials and biomarkers chosen for efficacy assessment for preventative, neoadjuvant, adjuvant, and palliative treatments. Cancer treatments could be evaluated by assessing stem cell markers before and after treatment. Targeted stem cell specific treatment of cancers may not result in “complete” or “partial” responses radiologically, as stem cell targeting may not reduce the tumor bulk, but eliminate further tumorigenic potential.

    More than three decades since its discovery, HIV infection remains one of the most aggressive epidemics worldwide, with more than 35 million people infected. In sub-Saharan Africa, heterosexual transmissions represent nearly 80% of new infections, with 50% of these occurring in women. In an effort to stop the dramatic spread of the HIV epidemic, new preventive treatments, such as microbicides, have been developed. Nanotechnology has revolutionized this field by designing and engineering novel highly effective nano-sized materials as microbicide candidates. This review illustrates the most recent advances in nanotech-derived HIV prevention strategies, as well as the main steps required to translate promising in vitro results into clinical trials.

    Doppler ultrasound (DUS) is used as a screening tool to assess internal carotid artery (ICA) disease. Recent reports suggest that the DUS may be inaccurate in over 28% of patients. We sought to evaluate the accuracy of DUS, when performed in a dedicated stroke prevention clinic (SPC). We retrospectively reviewed the charts of patients who had a DUS performed in our SPC, followed by conventional cerebral angiography. Three groups of patients were defined. Group 1 had DUS measured ICA stenosis of >50%; Group II had a DUS measured ICA stenosis of 50%--a misclassification rate of 0%. Group III consisted of five patients in whom DUS showed complete ICA occlusion. The angiogram confirmed the occlusion in all five patients--a misclassification rate of 0%. Overall, misclassification rate was 1.45% (95% CI: 0 - 4.3%). Doppler ultrasound when performed in a stroke prevention clinic (SPC), has a high accuracy in measuring ICA stenosis of >50%. Doppler ultrasound is reliable in detecting complete ICA occlusion and finally DUS is a reliable screening tool to rule out clinically significant ICA stenosis.

    The eating habits modification is a clinical challenge, both on therapeutic and preventive levels, which requires tools from various areas of health, such as psychology and nutrition. In the structured work in these areas, that includes the referral to specialist consultants, there is a need of a first intervention in Primary Health Care, in clinical and community levels. In this paper, we attempt to systematize useful information for intervention. We will start by reviewing some important interviewing skills, some models of motivational interviewing, and we will make a brief reflection about the client. Then we will analyse an individual case structured in two complementary levels of interpretation: a closer look in general factors and another that reflect the antecedents, consequences and the description of the behaviour problem. We will also tackle issues related to the context in which the individual moves. We will analyse some group intervention programs within a clinical and preventive perspectives. Finally, we will discuss some concepts related to therapeutic adherence.

    In view of the fact that the suicide rate in Japan has remained high since 1998, the Basic Act on Suicide Prevention was implemented in 2006 with the objective of comprehensively promoting suicide prevention measures on a national scale. Based on this Basic Act, in 2007, the Japanese government formulated the General Principles of Suicide Prevention Policy as a guideline for recommended suicide prevention measures. These General Principles were revised in 2012 in accordance with the initial plan of holding a review after five years. The Basic Act places an emphasis on the various social factors that underlie suicides and takes the perspective that suicide prevention measures are also social measures. The slogan of the revised General Principles is "Toward Realization of a Society in which Nobody is Driven to Commit Suicide". The General Principles list various measures that are able to be used universally. These contents would be sufficient if the objective of the General Principles were "realization of a society that is easy to live in"; however, the absence of information on the effectiveness and order of priority for each measure may limit the specific effectiveness of the measures in relation to the actual prevention of suicide. In addition, considering that nearly 90% of suicide victims are in a state at the time of committing suicide in which a psychiatric disorder would be diagnosed, it would appear from a psychiatric standpoint that measures related to mental health, including expansion of psychiatric services, should be the top priority in suicide prevention measures. However, this is not the case in the General Principles, in either its original or revised form. Revisions to the General Principles related to clinical psychiatry provide more detailed descriptions of measures for individuals who unsuccessfully attempt suicide and identify newly targeted mental disorders other than depression; however, the overall proportion of contents relating to

    Gingival invaginations develop after tooth extraction and subsequent orthodontic space closure. Aetiological factors and long-term effects of gingival invaginations on oral health are nearly unknown. In addition, preventive or therapeutic strategies are rare. This prospective clinical study employing the split mouth technique was performed to investigate the effect of extraction socket augmentation with a synthetic nanocrystalline hydroxyapatite (NanoBone(®) Artoss, Rostock, Germany) on the incidence and degree of gingival invaginations. A total of 10 orthodontic patients with need for symmetric premolar extractions offering a total of 28 extractions were included in this trial. The study plan provided one extraction site to be augmented with synthetic nanocrystalline hydroxyapatite (NanoBone(®)), the other served as control. After primary wound healing, space closure was performed under defined biomechanical conditions. After space closure was accomplished, occurrence and degree of gingival invaginations as well as probing depths of the adjacent teeth mesial and distal to the extractions were determined and dental radiographs were taken. The degree of gingival invaginations and probing depths mesial and distal of the extraction were significantly reduced on NanoBone(®) augmented extraction sites. In addition, 70% of the radiographs revealed translucent and hyperdense areas on the intervention side after space closure. Apical root resorption was found in 2 patients on both the NanoBone(®) side and the control side. Ridge preservation with NanoBone(®) appeared to reduce the severity of gingival invaginations. Further investigation on long-term effects is mandatory to eliminate the appearance of adverse effects.

Its progress is extremely fast, with extensive necrosis. Delay in treatment, with subsequent huge soft tissue loss and associated severe sepsis, remains a major cause of death in the management of NF. Objective: The aim of this study was to explore clinical characteristics that may be used to predict severe sepsis in patients with NF, in the context of routine clinical practice in northern Thailand. Methods: A retrospective observational cohort study was conducted. The patient cohort in this study consisted of all patients who were diagnosed with NF by surgical or pathological confirmation. The follow-up period started with the admission date and ended with the discharge date. The clinical variables were collected from patients registered at three provincial hospitals in northern Thailand from 2009 to 2012. The clinical predictors for severe sepsis were analyzed using multivariable risk regression. Results: A total of 1,452 patients were diagnosed with NF, either with severe sepsis (n=237 [16.3%] or without severe sepsis (n=1,215 [83.7%]. From the multivariable analysis, female sex (relative risk [RR] =1.51; 95% confidence interval [CI] =1.04–2.20, diabetes mellitus (RR =1.40; 95% CI =1.25–1.58, chronic heart disease (RR =1.31; 95% CI =1.15–1.49, hemorrhagic bleb (RR =1.47; 95% CI =1.32–1.63, skin necrosis (RR =1.45; 95% CI =1

    Familial exudative vitreoretinopathy (FEVR) is a rare hereditary retinal disorder characterized by the premature arrest of vascularization in the peripheral retina. The aim of the present study was to characterize the clinical presentations of a Chinese family affected by bilateral severe FEVR, and to identify the underlying genetic variations. One family that presented with bilateral FEVR was recruited for this study. Comprehensive ophthalmic examinations, including best‑corrected visual acuity, slit‑lamp examination, fundus photography, fundus fluorescein angiography imaging and electroretinogram were performed. Genomic DNA was extracted from leukocytes of the peripheral blood collected from the affected and unaffected family members, as well as 200 unrelated control subjects from the same population. Next‑generation sequencing of the candidate genes associated with ocular diseases was performed, and the identified mutations were validated by conventional polymerase chain reaction‑based sequencing. The functional effects of the mutations were analyzed by polymorphism phenotyping (PolyPhen) and sorting intolerant from tolerant (SIFT). One heterozygous ATP binding cassette subfamily A member 4 (ABCA4) c.5693G>A (p.R1898H) mutation in exon 40 and one heterozygous LDL receptor related protein 5 (LRP5) c.260T>G (p.I87S) mutation in exon 2 were identified in this family. To the best of our knowledge, the ABCA4 c.5693G>A (p.R1898H) mutation has not been reported in FEVR, and the LRP5 c.260T>G (p.I87S) mutation is a novel mutation. PolyPhen and SIFT predicted that the amino acid substitution R1898H in protein ABCA4 is benign, whereas the amino acid substitution I87S in protein LRP5 is damaging. A single nucleotide polymorphism c.266A>G (p.Q89R, rs41494349) was identified in exon 2 of LRP5. These findings expand the mutation spectrums of ABCA4 and LRP5, and will be valuable for genetic counseling and development of therapeutic interventions for patients with

    Full Text Available Abstract Background Cardiovascular diseases (CVD are the leading cause of death and the third cause of disability in Europe. Prevention programmes should include interventions aimed at a reduction of medical risk factors (hypertension, hypercholesterol, hyperglycemia, overweight and obesity as well as behavioural risk factors (sedentary lifestyle, high fat intake and low fruit and vegetable intake, smoking. The aim of this study is to investigate the effects of a multifaceted, multidisciplinary electronic prevention programme on cardiovascular risk factors. Methods/Design In a randomized controlled trial, one group will receive a maximal intervention (= intervention group. The intervention group will be compared to the control group receiving a minimal intervention. An inclusion of 350 patients in total, with a follow-up of 3 years is foreseen. The inclusion criteria are age between 25–65 and insured by the Onderlinge Ziekenkas, insuring for guaranteed income in case of illness for self-employed. The maximal intervention group receives several prevention consultations by their general practitioner (GP using a new type of cardiovascular risk calculator with personalised feedback on behavioural risk factors. These patients receive a follow-up with intensive support of health behaviour change via different methods, i.e. a tailored website and personal advice of a multidisciplinary team (psychologist, physiotherapist and dietician. The aim of this strategy is to reduce cardiovascular risk factors according to the guidelines. The primary outcome measures will be cardiovascular risk factors. The secondary outcome measures are cardiovascular events, quality of life, costs and incremental cost effectiveness ratios. The control group receives prevention consultations using a new type of cardiovascular risk calculator and general feedback. Discussion This trial incorporates interventions by GPs and other health professionals aiming at a reduction of

    This review evaluates costs and benefits associated with acquiring, implementing, and operating clinical decision support systems (CDSSs) to prevent cardiovascular disease (CVD). Methods developed for the Community Guide were used to review CDSS literature covering the period from January 1976 to October 2015. Twenty-one studies were identified for inclusion. It was difficult to draw a meaningful estimate for the cost of acquiring and operating CDSSs to prevent CVD from the available studies ( n  = 12) due to considerable heterogeneity. Several studies ( n  = 11) indicated that health care costs were averted by using CDSSs but many were partial assessments that did not consider all components of health care. Four cost-benefit studies reached conflicting conclusions about the net benefit of CDSSs based on incomplete assessments of costs and benefits. Three cost-utility studies indicated inconsistent conclusions regarding cost-effectiveness based on a conservative $50,000 threshold. Intervention costs were not negligible, but specific estimates were not derived because of the heterogeneity of implementation and reporting metrics. Expected economic benefits from averted health care cost could not be determined with confidence because many studies did not fully account for all components of health care. We were unable to conclude whether CDSSs for CVD prevention is either cost-beneficial or cost-effective. Several evidence gaps are identified, most prominently a lack of information about major drivers of cost and benefit, a lack of standard metrics for the cost of CDSSs, and not allowing for useful life of a CDSS that generally extends beyond one accounting period.

    Differentiated gastric cancer generally develops in the atrophic gastric mucosa, although undifferentiated cancer is sometimes encountered in patients with severe atrophic gastritis. We characterized the endoscopic features of undifferentiated gastric cancer in patients with severe atrophic gastritis. Stage IA early gastric cancer was diagnosed in 501 patients who were admitted to our hospital between April 2003 and March 2012. The endoscopic and pathological findings were compared among 29 patients with undifferentiated cancer and severe atrophic gastritis, 104 patients with undifferentiated cancer and mild/moderate atrophic gastritis and 223 patients with well-differentiated cancer and severe atrophic gastritis. Endoscopic atrophic gastritis was classified according to the Kimura-Takemoto classification as no gastritis, C-1 and C-2 (mild), C-3 and O-1 (moderate) or O-2 and O-3 (severe). The tumors were larger and showed deeper mural invasion in the patients with undifferentiated cancer and severe atrophic gastritis than in those with well-differentiated cancer and severe gastritis or undifferentiated cancer and mild/moderate gastritis. On endoscopy, undifferentiated cancer associated with severe gastritis was often red in color. It is often difficult to diagnose early undifferentiated gastric cancer, especially in patients with severe atrophic gastritis. The present study characterized the important endoscopic features of such tumors.

    The aims of this study were to explore pressure ulcer incidences and practice variations in the nursing intervention provided for preventive pressure-ulcer care to patients either with pressure ulcers or at risk of pressure ulcers, and to examine them in relation to the patients' medical problems and the characteristics of the nurses who cared for them. The narrative nursing notes of 427 intensive-care patients who were discharged in 2007 that were documented at the point-of-care using standardized nursing statements were extracted from a clinical data repository at a teaching hospital in Korea and analyzed. The frequencies of five nursing interventions for pressure-ulcer prevention were compared between pressure-ulcer and pressure-ulcer risk groups, as were the characteristics of the nurses who were treating the patients in these two groups. Nursing interventions for pressure-ulcer prevention were also assessed relative to the patients' medical problems. The overall incidence of pressure ulcers was 15.0%. Position change was the most popular nursing intervention provided for pressure-ulcer prevention in both the pressure-ulcer and at-risk groups, followed by skin care. There was a statistically significant tendency toward a greater frequency of providing skin care and nutritional care in the at-risk group than in the pressure-ulcer group. There was no statistically significant difference in the mean frequencies of nursing interventions relative to the patients' medical problems in the pressure-ulcer group. However, frequencies of nursing interventions did differ significantly between patients with neurological problems and those with other medical problems in the at-risk group. Analysis of the nurses' characteristics revealed that more nursing interventions were documented by those who were younger, less experienced, and more educated. A standardized nursing-terminology-based electronic nursing record system allowed us to monitor the variations in nursing practice

    Our team is designing and fully characterizing black raspberry (BRB) food products suitable for long-term cancer prevention studies. The processing, scale-up, and storage effects on the consistency, quality, bioactive stability, and sensory acceptability of two BRB delivery systems of various matrices are presented. BRB dosage, pH, water activity, and texture were consistent in the scale-up production. Confections retained >90% of anthocyanins and ellagitannin after processing. Nectars had >69% of anthocyanins and >66% of ellagitannin retention, which varied with BRB dosage due to the processing difference. Texture remained unchanged during storage. BRB products consumed in a prostate cancer clinical trial were well accepted in sensory tests. Thus, this study demonstrates that two different BRB foods can be formulated to meet quality standards with a consistent bioactive pattern and successfully scaled up for a large human clinical trial focusing on cancer risk and other health outcomes.

    The American College of Physicians (ACP) developed this guideline to present the evidence and provide clinical recommendations based on the comparative effectiveness of risk assessment scales and preventive interventions for pressure ulcers. This guideline is based on published literature on this topic that was identified by using MEDLINE (1946 through February 2014), CINAHL (1998 through February 2014), the Cochrane Library, clinical trials registries, and reference lists. Searches were limited to English-language publications. The outcomes evaluated for this guideline include pressure ulcer incidence and severity, resource use, diagnostic accuracy, measures of risk, and harms. This guideline grades the quality of evidence and strength of recommendations by using ACP's clinical practice guidelines grading system. The target audience for this guideline includes all clinicians, and the target patient population is patients at risk for pressure ulcers. ACP recommends that clinicians should perform a risk assessment to identify patients who are at risk of developing pressure ulcers. (Grade: weak recommendation, low-quality evidence). ACP recommends that clinicians should choose advanced static mattresses or advanced static overlays in patients who are at an increased risk of developing pressure ulcers. (Grade: strong recommendation, moderate-quality evidence). ACP recommends against using alternating-air mattresses or alternating-air overlays in patients who are at an increased risk of developing pressure ulcers. (Grade: weak recommendation, moderate-quality evidence).

    Numerous reports indicate that the incidence of posttraumatic stress disorder (PTSD) in Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) military personnel has created a significant behavioural healthcare challenge. These findings have served to motivate research on how to better develop and disseminate evidence-based treatments for PTSD. The current article presents the use of Virtual Reality (VR) as a clinical tool to address the assessment, prevention, and treatment of PTSD, based on the VR projects that were evolved at the University of Southern California Institute for Creative Technologies since 2004. A brief discussion of the definition and rationale for the clinical use of VR is followed by a description of a VR application designed for the delivery of prolonged exposure (PE) for treating Service Members (SMs) and Veterans with combat- and sexual assault-related PTSD. The expansion of the virtual treatment simulations of Iraq and Afghanistan for PTSD assessment and prevention is then presented. This is followed by a forward-looking discussion that details early efforts to develop virtual human agent systems that serve the role of virtual patients for training the next generation of clinical providers, as healthcare guides that can be used to support anonymous access to trauma-relevant behavioural healthcare information, and as clinical interviewers capable of automated behaviour analysis of users to infer psychological state. The paper will conclude with a discussion of VR as a tool for breaking down barriers to care in addition to its direct application in assessment and intervention.

    One of the main severe asthma phenotypes is severe eosinophilic or eosinophilic refractory asthma for which novel biologic agents are emerging as therapeutic options. In this context, blood eosinophil counts are one of the most reliable biomarkers. To evaluate the performance of a point-of-care peripheral blood counter in a patients with severe asthma. The blood eosinophil counts of 76 patients with severe asthma were evaluated by point-of-care and standard analyzers. A significant correlation between blood eosinophils assessed by the 2 devices was found (R 2  = 0.854, P asthma and the ELEN index, a composite score useful to predict sputum eosinophilia. The results of our study contribute to the validation of a point-of-care device to assess blood eosinophils and open the possibility of using this device for the management of severe asthma management.

    Hospitalized medical and surgical patients encompass a group of patients in whom venous thromboembolism (VTE) poses a major concern on morbidity and mortality. Recently, direct oral anticoagulants for the prevention of VTE have been developed to overcome the drawbacks of the food/drug interactions and the need for frequent laboratory monitoring and dose adjustments associated with the use of vitamin K antagonists and the inconvenience of the subcutaneous administration of low-molecular-weight heparins and fondaparinux. The novel oral anticoagulants that have been tested in major clinical trials for VTE prevention in medical and surgical patients are the thrombin inhibitor dabigatran and the factor Xa inhibitors apixaban, rivaroxaban, and edoxaban, which will be the focus of this review. While the new drugs proved to be highly effective and safe in the prevention of VTE following major orthopedic surgery, they failed to show a favorable benefit-to-risk profile in hospitalized medical patients receiving extended anticoagulation beyond the hospital stay.

    To evaluate the efficacy and safety of auto-crosslinked hyaluronic acid (HA) gel for preventing intrauterine adhesion (IUA) after hysteroscopic adhesiolysis. A prospective, randomized, double blinded and controlled clinical trial (level I) was performed. According to American Fertility Society (AFS) scoring system, 120 patients (treatment group: 60 cases, control group: 60 cases) with moderate to severe IUA were enrolled. Upon completion of adhesiolysis, a Foley balloon catheter was first introduced into the uterine cavity and then 3 ml of auto-crosslinked HA gel for patients in the treatment group; patients in the control group, however, only received Foley balloon catheter. Second-look hysteroscopic examination was performed to all patients at 3 months postoperatively for evaluation of IUA. Primary endpoint was the reduction rate of IUA at 3 months after surgery. The secondary endpoints include total AFS score, score of each individual AFS category. At 3 months after surgery, auto-crosslinked HA gel resulted in significantly higher effective rate for reduction of adhesion, the effective rate were 76% (42/55) and 48% (27/56) respectively (P = 0.000 9); the total AFS score of treatment group was 2.1 ± 1.1, and significantly lower than that of control group (3.7 ± 2.5, P = 0.000 8). Application of auto-crosslinked HA gel after surgery significantly enhanced the improvement for each individual patient with regard to their adhesive type and menstrual pattern (P = 0.037 8, P = 0.000 4). The treatment group had significantly lower proportion of patients with moderate to severe adhesive stages than that of control group [13% (7/55) versus 38% (21/56), P = 0.000 6]. No adverse events and complications were observed. Auto-crosslinked HA gel coule be able to reduce IUA, decrease adhesion severity, and improve menopause postoperatively. This absorbable auto-crosslinked HA gel is proposed as a barrier for preventing IUA after intrauterine procedures.

    To identify the clinical empirical evidence for identifying, managing and preventing skin maceration in human subjects. A rapid review of the current literature was undertaken between 5 September and 19 September 2016 using the electronic databases CINAHL, MEDLINE, PUBMED and Cochrane, with the key words: skin macerat*, wound macerat*, moisture associated skin damage, wound exudate and hyper-hydration of skin, Results: Of 526 papers found using an electronic database search, four were identified as fitting the search parameters, and a further two were retrieved from a manual search of reference lists. There were three themes that emerged: how to identify and measure maceration, how to manage and reduce maceration once it has already occurred, and how to prevent skin maceration. Hyper-hydration can reach greater skin depths than previously thought, thus engendering more extensive damage potential, which in turn can impact on treatments and healing time. Realistically, the deeper the hyper-hydration issue, the more extensive the damage and it will take longer to recover-a problem compounded if the hyper-hydration is due to incontinence and skin is also exposed to urine and/or faeces. In relation to wound management, the authors advocate the removal of moisture away from the wound or skin, either through superabsorbent dressings, or by allowing the excess moisture to evaporate through semi-permeable dressings to reduce maceration, enhance patient comfort and encourage healing. However, we found no evidence regarding the limits of hydration of the dermis and epidermis and thereby the optimal conditions for managing exuding wounds and promoting skin health. Each of the six papers in this review calls for further research to help identify, treat and prevent maceration. Maceration causes patients' discomfort and pain as well as prolonging healing time and deserves more focused research. This rapid review highlights how limited the clinical empirical research is on

    Dental Therapists and Oral Health Therapists (Therapists) working in the New South Wales (NSW) Public Oral Health Service are charged with providing clinical dental treatment including preventive care for all children under 18 years of age. Adolescents in particular are at risk of dental caries and periodontal disease which may be controlled through health education and clinical preventive interventions. However, there is a dearth of evidence about the type or the proportion of clinical time allocated to preventive care.The aim of this study is to record the proportion and type of preventive care and clinical treatment activities provided by Therapists to adolescents accessing the NSW Public Oral Health Service. Clinical dental activity data for adolescents was obtained from the NSW Health electronic Information System for Oral Health (ISOH) for the year 2011. Clinical activities of Therapists were examined in relation to the provision of different types of preventive care for adolescents by interrogating state-wide public oral health data stored on ISOH. Therapists were responsible for 79.7 percent of the preventive care and 83.0 percent of the restorative treatment offered to adolescents accessing Public Oral Health Services over the one year period. Preventive care provided by Therapists for adolescents varied across Local Health Districts ranging from 32.0 percent to 55.8 percent of their clinical activity. Therapists provided the majority of clinical care to adolescents accessing NSW Public Oral Health Services. The proportion of time spent undertaking prevention varied widely between Local Health Districts. The reasons for this variation require further investigation.

    Full Text Available Aim: Prompt diagnosis and determination of the clinical severity and intervention of lower respiratory tract infections (LRTI is essential for the prevention and management of life-threatening complications. Laboratory tests do not serve as accurate indicators of clinical severity. Our aim was to evaluate the contribution of urinary amino-terminal pro-brain natriuretic peptide (NT-ProBNP concentrations in children with LRTI to clinical assessment in terms of determining clinical severity and the necessity of hospitalization. Materials and Methods: This prospective non-randomised study included a total of 160 patients, aged 0-6 years, diagnosed with LRTI [(group 1=outpatient group (n=108, and (group 2=hospitalized patients (n=52]. The control group (group 3 was comprised of 46 healthy children. Urinary NT-ProBNP level of each participant was measured by ELISA method. Results: Although not significant, the mean urinary NT-ProBNP level of all patients was higher than that of the control group (p=0.322. When we compared the three groups separately, the highest levels belonged to outpatients whereas hospitalized patients showed slightly lower levels than the control group without any statistical significance (p=0.128. As for newborns (n=16, patients showed higher levels than the controls (p=0.041. P value <0.05 was considered significant. Conclusion: Although urinary NT-ProBNP level tends to increase to some extent in childhood LRTI, this alteration does not seem to be valuable in the prediction of the severity of the disease. We believe that the establishment of further studies including larger series of patients, especially neonates, is warranted.

    Pain, itching, burning and irritation are common symptoms of psoriasis but have not been well characterized by overall psoriasis severity. Using 2012 syndicated psoriasis patient survey data, 1050 subjects were classified into mild (n = 610) and moderate-to-severe (n = 440) psoriasis severity groups based on self-reporting. Demographics, comorbid medical conditions and patient-reported key symptoms (i.e. flare-up frequency, psoriasis-related pain, itching, burning, hurting, irritation) were compared between groups. Multiple regressions were employed to examine the impact of overall psoriasis severity on each key symptom, controlling for demographics and comorbidities. Mild patients were older; more than 20% in both groups had joint pain and depression. Over 35 and 68% of the moderate-to-severe patients reported severe pain between or during flare-ups, respectively, and over 79% reported frequent bothersome itching. Controlling for between-group differences, moderate-to-severe patients had worse pain, were more likely to have continual flare-ups (odds ratio = 3.0) and flare-ups more than once monthly (odds ratio = 3.0), and reported more bothersome symptoms than patients with mild disease (all p management.

    Full Text Available Background: The Mahalapye district health management team (DHMT conducts regular audits to evaluate the standard of services delivered to patients, one of which is the prevention of mother-to-child-transmission (PMTCT programme. Xhosa clinic is one of the facilities in Mahalapye which provides a PMTCT programme.Aim: This audit aimed to identify gaps between the current PMTCT clinical practice in Xhosa clinic and the Botswana PMTCT national guidelines.Setting: This audit took place in Xhosa clinic in the urban village of Mahalapye, in the Central District of Botswana.Methods: This was a retrospective audit using PMTCT Xhosa clinic records of pregnant mothers and HIV-exposed babies seen from January 2013 to June 2013.Results: One hundred and thirty-three pregnant women registered for antenatal care. Twenty-five (19% knew their HIV-positive status as they had been tested before their pregnancy or had tested HIV positive at their first antenatal clinic visit. More than two-thirds of the 115 pregnant women (69% were seen at a gestational age of between 14 and 28 weeks. About two-thirds of the pregnant women (67% took antiretroviral drugs. Of the 44 HIV-exposed infants, 39 (89% were HIV DNA PCR negative at 6 weeks. Thirty-two (73% children were given cotrimoxazole prophylaxis between 6 and 8 weeks.Conclusion: The PMTCT programme service delivery was still suboptimal and could potentially increase the mother-to-child transmission of HIV. Daily monitoring mechanism to track those eligible could help to close the gap.

    OBJECTIVE: Huntington disease (HD) is an autosomal dominant neurodegenerative disorder caused by a CAG repeat expansion in the HD gene (HTT). We aimed to assess whether interaction between CAG repeat sizes in the mutant and normal allele could affect disease severity and progression. METHODS: Using...... with less severe symptoms and pathology. CONCLUSIONS: Increasing CAG repeat size in normal HTT diminishes the association between mutant CAG repeat size and disease severity and progression in Huntington disease. The underlying mechanism may involve interaction of the polyglutamine domains of normal...

    Bone loss is a feature of both periodontitis and osteoporosis, and several studies have analyzed whether the periodontal destruction could have been influenced by systemic bone loss. The aim of this study is to assess the association between clinical attachment level (CAL) and bone mineral density (BMD) at the lumbar spine and hip, lifestyle, smoking, sociodemographic factors, and dental clinical variables in postmenopausal women. One hundred forty-eight women were interviewed using a structured written questionnaire and clinically examined. The periodontal examination, which was performed by calibrated investigators, included CAL, probing depth, gingival recession, bleeding on probing (BOP), visible plaque, supragingival calculus, and mean tooth loss. The sample was stratified into two groups: moderate and severe CAL. The moderate group had all sites with CAL ≤5 mm. The severe group had ≥1 site with CAL >5 mm. BMD, measured using dual-energy x-ray absorptiometry, was assessed at the lumbar spine, femoral neck, and total femur (grams per square centimeters). Severe CAL was identified in 86 women (58.1%). The multiple linear regression analysis using CAL (dependent variable), adjusted by menopause, education, and family income, demonstrated an inverse relationship of severe CAL with the BMD of the femoral neck (P = 0.015), as well as a positive association of severe CAL with tooth loss (P = 0.000), BOP (P = 0.004), and heavy smokers (P = 0.001). Our study demonstrated that severe CAL was associated with low BMD of the femoral neck and deleterious clinical dental parameters and smoking. Our findings suggest that, in addition to appropriate oral care, individuals with severe CAL may also require additional attention to their systemic bone health.

    A randomised trial of nurse-led secondary prevention clinics for coronary heart disease resulted in improved secondary prevention and significantly lowered all-cause mortality at 4-year follow-up. This qualitative trial was conducted to explore the experience of health professionals that had been involved in running the clinics. To identify the barriers and facilitators to establishing secondary prevention clinics for coronary heart disease within primary care. Semi-structured audiotaped telephone interviews with GPs and nurses involved in running clinics. A stratified, random sample of 19 urban, suburban, and rural general practices in north-east Scotland. Semi-structured telephone interviews with 19 GPs and 17 practice-based nurses involved in running nurse-led clinics for the secondary prevention of coronary heart disease. Eight practices had run clinics continuously and 11 had stopped, with eight subsequently restarting. Participants accounted for these patterns by referring to advantages and disadvantages of the clinics in four areas: patient care, development of nursing skills, team working, and infrastructure. Most practitioners perceived benefits for patients from attending secondary prevention clinics, but some, from small rural practices, thought they were unnecessary. The extended role for nurses was welcomed, but was dependent on motivated staff, appropriate training and support. Clinics relied on, and could enhance, team working, however, some doctors were wary of delegating. With regard to infrastructure, staff shortages (especially nurses) and accommodation were as problematic as lack of funds. Nurse-led secondary prevention clinics were viewed positively by most healthcare professionals that had been involved in running them, but barriers to their implementation had led most to stop running them at some point. Lack of space and staff shortages are likely to remain ongoing problems, but improvements in funding training and communication within

    HIV-1 sequencing has been used extensively in epidemiologic and forensic studies to investigate patterns of HIV-1 transmission. However, the criteria for establishing genetic linkage between HIV-1 strains in HIV-1 prevention trials have not been formalized. The Partners in Prevention HSV/HIV Transmission Study (ClinicaITrials.gov NCT00194519) enrolled 3408 HIV-1 serodiscordant heterosexual African couples to determine the efficacy of genital herpes suppression with acyclovir in reducing HIV-1 transmission. The trial analysis required laboratory confirmation of HIV-1 linkage between enrolled partners in couples in which seroconversion occurred. Here we describe the process and results from HIV-1 sequencing studies used to perform transmission linkage determination in this clinical trial. Consensus Sanger sequencing of env (C2-V3-C3) and gag (p17-p24) genes was performed on plasma HIV-1 RNA from both partners within 3 months of seroconversion; env single molecule or pyrosequencing was also performed in some cases. For linkage, we required monophyletic clustering between HIV-1 sequences in the transmitting and seroconverting partners, and developed a Bayesian algorithm using genetic distances to evaluate the posterior probability of linkage of participants sequences. Adjudicators classified transmissions as linked, unlinked, or indeterminate. Among 151 seroconversion events, we found 108 (71.5%) linked, 40 (26.5%) unlinked, and 3 (2.0%) to have indeterminate transmissions. Nine (8.3%) were linked by consensus gag sequencing only and 8 (7.4%) required deep sequencing of env. In this first use of HIV-1 sequencing to establish endpoints in a large clinical trial, more than one-fourth of transmissions were unlinked to the enrolled partner, illustrating the relevance of these methods in the design of future HIV-1 prevention trials in serodiscordant couples. A hierarchy of sequencing techniques, analysis methods, and expert adjudication contributed to the linkage

    Full Text Available Characterization of viruses in HIV-1 transmission pairs will help identify biological determinants of infectiousness and evaluate candidate interventions to reduce transmission. Although HIV-1 sequencing is frequently used to substantiate linkage between newly HIV-1 infected individuals and their sexual partners in epidemiologic and forensic studies, viral sequencing is seldom applied in HIV-1 prevention trials. The Partners in Prevention HSV/HIV Transmission Study (ClinicalTrials.gov #NCT00194519 was a prospective randomized placebo-controlled trial that enrolled serodiscordant heterosexual couples to determine the efficacy of genital herpes suppression in reducing HIV-1 transmission; as part of the study analysis, HIV-1 sequences were examined for genetic linkage between seroconverters and their enrolled partners.We obtained partial consensus HIV-1 env and gag sequences from blood plasma for 151 transmission pairs and performed deep sequencing of env in some cases. We analyzed sequences with phylogenetic techniques and developed a Bayesian algorithm to evaluate the probability of linkage. For linkage, we required monophyletic clustering between enrolled partners' sequences and a Bayesian posterior probability of ≥ 50%. Adjudicators classified each seroconversion, finding 108 (71.5% linked, 40 (26.5% unlinked, and 3 (2.0% indeterminate transmissions, with linkage determined by consensus env sequencing in 91 (84%. Male seroconverters had a higher frequency of unlinked transmissions than female seroconverters. The likelihood of transmission from the enrolled partner was related to time on study, with increasing numbers of unlinked transmissions occurring after longer observation periods. Finally, baseline viral load was found to be significantly higher among linked transmitters.In this first use of HIV-1 sequencing to establish endpoints in a large clinical trial, more than one-fourth of transmissions were unlinked to the enrolled partner

    Factors predisposing hormone-dependent tissues to the development of tumors coincide, at least partly, with hormonal-metabolic promoters (like insulin resistance, glucose intolerance, visceral obesity, etc.) of other main non-communicable diseases. This important knowledge poses the question of whether the same approach which is applied for prevention/treatment of a metabolic syndrome and the associated endocrine disorders might also be used in preventive and therapeutic oncology. Whereas an answer to this question remains controversial and is based mainly on experimental evidence, there is accumulating clinical data suggesting a practical significance of such a strategy, even though it is not to be considered as directly cytostatic. Among the many drugs under discussion, three groups of medicines (statins, antidiabetic biguanides, and thiazolidinediones) are the most attractive. The concept of metabolic rehabilitation is proposed and used practically in an adjuvant setting for the correction of the above-mentioned endocrine-metabolic disorders commonly found in cancer patients. The current use and aim of this approach is to improve the survival of patients and limit cancer progression. Nonetheless, it also appears potentially useful as a neoadjuvant therapy as well as a prophylactic treatment earlier in life for specific groups of people with hormone-associated enhanced oncological risk. It seems possible that certain hypolipidemic and antidiabetic medicines with pleiotropic effects might be combined with traditional antisteroid prevention/therapeutic approaches in routine clinical situations as well as for overcoming resistance to standard cancer hormonal therapies including receptor-negative cases. Characteristic at the end of the 20th and at the beginning of the 21st century is an epidemic of diabetes and obesity, which might further increase the incidence of certain cancers. This makes it timely to apply hypolipidemic and antidiabetic drugs (in combination

    The risk of post-traumatic osteoarthritis (PTOA) substantially increases following joint injury. Research efforts should focus on investigating the efficacy of preventative strategies in high quality randomized controlled trials (RCT). The objective of these OARSI RCT recommendations is to inform the design, conduct and analytical approaches to RCTs evaluating the preventative effect of joint injury prevention strategies. Recommendations regarding the design, conduct, and reporting of RCTs evaluating injury prevention interventions were established based on the consensus of nine researchers internationally with expertise in epidemiology, injury prevention and/or osteoarthritis (OA). Input and resultant consensus was established through teleconference, face to face and email correspondence over a 1 year period. Recommendations for injury prevention RCTs include context specific considerations regarding the research question, research design, study participants, randomization, baseline characteristics, intervention, outcome measurement, analysis, implementation, cost evaluation, reporting and future considerations including the impact on development of PTOA. Methodological recommendations for injury prevention RCTs are critical to informing evidence-based practice and policy decisions in health care, public health and the community. Recommendations regarding the interpretation and conduct of injury prevention RCTs will inform the highest level of evidence in the field. These recommendations will facilitate between study comparisons to inform best practice in injury prevention that will have the greatest public health impact.

    To identify specific clinical and epidemiological parameters for clinical diagnosis of SFTSV infection with relatively higher accuracy. 231 suspected cases of SFTS were reported by various medical institutions from 2011 to 2013 in Jiangsu Province, China. They were followed with SFTSV diagnosis tests and interview-administered questionnaires about demographic characteristics, clinical symptoms and epidemiological exposure factors. Univariate and multivariable logistic regression analysis were used to examine the diagnostic value of these parameters. SFTSV infection occurred only from April to October annually and usually in hilly areas of specific regions. Three prediction models of SFTSV infection were constructed. Model 3 with clinical and epidemiological parameters combined the benefits of both Model 1and Model 2, which was optimal and had an overall accuracy of 80.2%. Independent indicators for clinical diagnosis of SFTSV infection in Model 3 were as follows: lymphadenopathy (P = 0.01), leucopenia (P50 years (P = 0.01), tick bites (Pdiagnosis as differentiating SFTSV infection from SFTS-like diseases, thus reducing the risk of misdiagnosis.

    To evaluate the quality of clinical practice guidelines (CPGs) for dental caries prevention in children and adolescents MATERIALS AND METHODS: We performed a systematic search of CPGs on caries preventive measures between 2005 and 2016. We searched MEDLINE, EMBASE, LILACS, TripDatabase, websites of CPG developers, compilers of CPGs, scientific societies and ministries of health. We included CPGs with recommendations on sealants, fluorides and oral hygiene. Three reviewers independently assessed the included CPGs using the AGREE II instrument. We calculated the standardised scores for the six domains and made a final recommendation about each CPG. Also, we calculated the overall agreement among calibrated reviewers with the intraclass correlation coefficient (ICC). Twenty-two CPGs published were selected from a total of 637 references. Thirteen were in English and nine in Spanish. The overall agreement between reviewers was very good (ICC = 0.90; 95%CI 0.89-0.92). The mean score for each domain was the following: Scope and purpose 89.6 ± 12%; Stakeholder involvement 55.0 ± 15.6%; Rigour of development 64.9 ± 21.2%; Clarity of presentation 84.8 ± 14.1%; Applicability 30.6 ± 31.5% and Editorial independence 59.3 ± 25.5%. Thirteen CPGs (59.1%) were assessed as "recommended", eight (36.4%) "recommended with modifications" and one (4.5%) "not recommended". The overall quality of CPGs in caries prevention was moderate. The domains with greater deficiencies were Applicability, Stakeholder involvement and Editorial independence. Clinicians should use the best available CPGs in dental caries prevention to provide optimal oral health care to patients.

    To evaluate whether depressive symptom severity leads to poorer response and perceived adherence to cognitive behavioral therapy for insomnia (CBTI) and to examine the impact of CBTI on well-being, depressive symptom severity, and suicidal ideation. Pre- to posttreatment case replication series comparing low depression (LowDep) and high depression (HiDep) groups (based on a cutoff of 14 on the Beck Depression Inventory [BDI]). 127 men and 174 women referred for the treatment of insomnia. Seven sessions of group CBTI. Improvement in the insomnia severity, perceived energy, productivity, self-esteem, other aspects of wellbeing, and overall treatment satisfaction did not differ between the HiDep and LowDep groups (p > 0.14). HiDep patients reported lower adherence to a fixed rise time, restricting time in bed, and changing expectations about sleep (p self-esteem, and other aspects of well-being were similar among patients with and without elevation in depressive symptom severity. Thus, the benefits of CBTI extend beyond insomnia and include improvements in non-sleep outcomes, such as overall well-being and depressive symptom severity, including suicidal ideation, among patients with baseline elevations. Results identify aspects of CBTI that may merit additional attention to further improve outcomes among patients with insomnia and elevated depressive symptom severity.

We assess if any epidemiological or clinical factors in SARS index patients were associated with increased probability of transmission. Methods We used epidemiological and clinical data on probable SARS patients admitted to Tan Tock Seng Hospital. Using a case-control approach, index patients who had probable SARS who subsequently transmitted the disease to at least one other patient were analysed as "cases" against patients with no transmission as "controls", using multivariate logistic regression analysis. Results 98 index patients were available for analysis (22 with transmission, 76 with no transmission. Covariates positively associated with transmission in univariate analysis at p 650 IU/L (OR 6.4, 23.8 and 4.7 respectively. Conclusion Clinical and epidemiological factors can help us to explain why transmission was observed in some instances but not in others.

    Full Text Available Omega-3 polyunsaturated fatty acids (n-3 PUFAs are believed to be important for cardiovascular health. Many investigations have been carried out in an attempt to examine the effect of n-3 PUFAs intake, in the form of supplementation or fortified foods, for the management of cardiovascular disease (CVD and risk factors for CVD, whereas less is known about the effect on healthy individuals. The present study reviews the available literature in order to examine the relationship between n-3 PUFAs intake, either via supplementation or enriched food, and the prevention of CVD among healthy adults. Interventional clinical trials on subjects aged >18 years old with none of the established risk factors for CVD have been considered for review. n-3 PUFAs supplementation or enriched food may positively regulate triglycerides and some lipoprotein subsets, as well as several vascular and coagulation parameters, even in healthy patients, presenting no risk factors for CVD, suggesting a protective effect. Diet enrichment with omega-3 is likely to be useful in helping to lower the risk of developing CVD in healthy individuals, but still offers no strong evidence of a tangible benefit on a population level. Additional studies are needed to determine the optimal daily intake, especially to prevent the unfavorable effects of PUFAs over-consumption.

    Accurate identification of paediatric patients with severe asthma is essential for an adequate management of the disease. However, criteria for defining severe asthma and recommendations for control vary among different guidelines. An online survey was conducted to explore expert opinions about the definition and management of severe paediatric asthma. To reach a consensus agreement, a modified Delphi technique was used, and practice guidelines were prepared after the analysis of the results. Eleven paediatric chest disease physicians and allergy specialists with wide expertise in severe asthma responded to the survey. Consensus was reached in 50 out of 65 questions (76.92%). It was considered that a patient has severe asthma if during the previous year they have required 2 or more cycles of oral steroids, required daily treatment with medium doses of inhaled corticosteroids (with other controller medication) or high doses (with or without other controller medication), did not respond to optimised conventional treatment, or if the disease threatened the life of the patient or seriously impairs their quality of life. The definition of severe asthma may also include patients who justifiably use health resources on a regular basis, or have psychosocial or environmental factors impeding control. For monitoring, the use of questionnaires designed specifically for paediatric population, such as CAN or ACT, is recommended. As regards treatment, the use of omalizumab should be considered prior to the use of oral corticosteroids. This paper provides consensus recommendations that may be useful in the management of severe paediatric asthma. Copyright © 2015 Asociación Española de Pediatría. Published by Elsevier España, S.L.U.

    Cadegiani, Flavio A; Diniz, Gustavo C; Alves, Gabriella

    2017-01-01

    The number of bariatric procedures has exponentially increased in the past decade, as a result of the lack of successful clinical weight-loss interventions. The main reasons for the failure of clinical obesity management are: (1) anti-obesity medications are administered as monotherapies (or pre-combined drugs); (2) lack of combination between pharmacotherapy and non-pharmacological modalities; (3) short duration of pharmacotherapy for obesity; (4) lack of weight-loss maintenance strategies; (5) misunderstanding of the complex pathophysiology of obesity; and (6) underprescription of anti-obesity medications. We developed a protocol that can potentially overcome the drawbacks that may lead to the failure of clinical therapy for obesity. The aim of this study is therefore to report the clinical and metabolic effects of our proposed obesity-management protocol over a 2-year period, and to determine whether this more intensive approach to obesity management is feasible and a possible alternative to bariatric surgery in patients with moderate-to-severe obesity. This retrospective study involved 43 patients in whom bariatric surgery was indicated. Patients underwent an intensive anti-obesity protocol that included pharmacotherapy with multiple drugs; intense surveillance with monthly body analysis by air-displacement plethysmography, electrical bioimpedance, and 3D body scans; weekly psychotherapy; diet planning with a dietician every 2 months; and exercises at least 3 times a week with exercises prescribed by a personal trainer at least once a month. Body weight (BW), total weight excess (TWE), obesity class, body mass index, fat weight, muscle weight, waist circumference, and visceral fat were analyzed. Markers of lipid and glucose metabolism, liver function, and inflammation were also evaluated. Therapeutic success was defined as >20% BW loss or >50% decrease in TWE after 1 year. Significant improvements were observed in all clinical and metabolic parameters. Thirty

    In rural India, mobile medical clinics are useful models for delivering health promotion, education, and care. Mobile medical clinics use fewer providers for larger catchment areas compared to traditional clinic models in resource limited settings, which is especially useful in areas with shortages of healthcare providers and a wide geographical distribution of patients. From 2008 to 2011, we built infrastructure to implement a mobile clinic system to educate rural communities about maternal child health, train community health workers in common safe birthing procedures, and provide comprehensive antenatal care, prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV), and testing for specific infections in a large rural catchment area of pregnant women in rural Mysore. This was done using two mobile clinics and one walk-in clinic. Women were tested for HIV, hepatitis B, syphilis, and bacterial vaginosis along with random blood sugar, urine albumin, and anemia. Sociodemographic information, medical, and obstetric history were collected using interviewer-administered questionnaires in the local language, Kannada. Data were entered in Microsoft Excel and analyzed using Stata SE 14.1. During the program period, nearly 700 community workers and 100 health care providers were trained; educational sessions were delivered to over 15,000 men and women and integrated antenatal care and HIV/sexually transmitted infection testing was offered to 3545 pregnant women. There were 22 (0.6%) cases of HIV, 19 (0.5%) cases of hepatitis B, 2 (0.1%) cases of syphilis, and 250 (7.1%) cases of BV, which were identified and treated. Additionally, 1755 (49.5%) cases of moderate to severe anemia and 154 (4.3%) cases of hypertension were identified and treated among the pregnant women tested. Patient-centered mobile medical clinics are feasible, successful, and acceptable models that can be used to provide quality healthcare to pregnant women in rural and

    Sodium-glucose cotransporter 2 (SGLT2) inhibitors are the newest class of antihyperglycemic agents available on the market. Regulator warnings and concerns regarding the risk of developing diabetic ketoacidosis (DKA), however, have dampened enthusiasm for the class despite the combined glycemic, blood pressure, and occasional weight benefits of SGLT2 inhibitors. With the goal of improving patient safety, a cross-Canada expert panel and writing group were convened to review the evidence to-date on reported SGLT2 inhibitor-related DKA incidents and to offer recommendations for preventing and recognizing patients with SGLT2 inhibitor-associated DKA. Reports covering DKA events in subjects taking SGLT2 inhibitors that were published in PubMed, presented at professional conferences, or in the public domain from January 2013 to mid-August 2016 were reviewed by the group independently and collectively. Practical recommendations for diagnosis and prevention were established by the panel. DKA is rarely associated with SGLT2 inhibitor therapy. Patients with SGLT2 inhibitor-associated DKA may be euglycemic (plasma glucose level diabetes, including those with type 2 diabetes, and is typically precipitated by insulin omission or dose reduction, severe acute illness, dehydration, extensive exercise, surgery, low-carbohydrate diets, or excessive alcohol intake. SGLT2 inhibitor-associated DKA may be prevented by withholding SGLT2 inhibitors when precipitants develop, avoiding insulin omission or inappropriate insulin dose reduction, and by following sick day protocols as recommended. Preventive strategies should help avoid SGLT2 inhibitor-associated DKA. All SGLT2 inhibitor-treated patients presenting with signs or symptoms of DKA should be suspected to have DKA and be investigated for DKA, especially euglycemic patients. If DKA is diagnosed, SGLT2 inhibitor treatment should be stopped, and the DKA should be treated with a traditional treatment protocol. Copyright © 2016 Elsevier

  2. An intrepreneurial innovative role: integration of the clinical nurse specialist and infection prevention professional.

    Hospital quality and financial sustainability rely on reducing healthcare-associated events/infections, length of stay, and readmissions. This project focused on designing an integrated role for the clinical nurse specialist (CNS) and the infection prevention professional (IPP) to proactively manage the delivery of evidence-based practice to high-risk surgical patients. The healthcare industry is in the midst of a paradigm shift driven by changing health policy focusing on quality indicators, patient satisfaction, and lowering costs. Coupled with these indicators is the expectation and responsibility to provide evidence-based practice at all levels of the healthcare continuum. This paradigm shift places healthcare facilities in a very competitive atmosphere as they rally for the revenue of a fixed payer mix. A literature search using CINHAL, PubMed, and the CNS national listserve databases was completed to identify if there was any previously written information available on an integrated role of the CNS/IPP. An online business plan template was used to communicate the significance, implications, and return on organizational investment to practice with establishing this role. Chronic health conditions such as diabetes, hypertension, congestive heart failure, and colonization with multidrug-resistant organisms can place patients at an increased risk for developing a surgical site infection or complications. The CNS/IPP will proactively manage these risk factors, including the patient and family in a preventive care model to manage the acute inpatient high-risk surgical patient. Care management will include coordinated, collaborative, and consultative follow-up by the CNS/IPP in the acute care, long-term care facilities, and home settings. The infection prevention skill set brings a level of clinical expertise that makes a unique CNS. The IPP is immersed in using epidemiological principles that examine the impact of comorbidities and the added risk that can

    Novel rosacea treatments are needed. Assessment methodologies for clinical trials of rosacea treatments are not standardized and are relatively inadequate. To determine the efficacy of new treatments, a valid and reliable assessment methodology is needed. We sought to determine the assessment methodologies used in clinical trials for rosacea treatments, to demonstrate the need for a valid and reliable assessment tool, and to describe the relevant properties of such a tool. PubMed and MEDLINE were searched for clinical trials of rosacea treatments since January 1, 1985. In all, 32 clinical trials met inclusion criteria. Assessment methodologies were highly variable, and standardized assessment methodologies were used in only 3 studies. The various manifestations of rosacea were assessed inconsistently. Eighteen articles could not be included as a result of lack of access to the full text. The diverse methodologies make the assessment of novel treatments and comparison of treatments difficult. A valid and reliable assessment tool is needed to properly assess novel treatments to improve the management of rosacea. Copyright © 2015 American Academy of Dermatology, Inc.

    While present in the surface membrane of embryonic muscle fibers, in adult normal muscle fibers, utrophin is restricted to the motor endplate and cells of blood vessel walls. However, the observation that utrophin is maintained in the extrajunctional plasma membrane in Duchenne (DMD) and in mdx muscle fibers has led to the suggestion that excess utrophin might compensate for dystrophin deficiency in the Xp21 muscular dystrophies. In order to detect an inverse correlation of utrophin presence and clinical severity, we have assessed utrophin distribution and quantity in DMD and Becker (BMD) patients of different ages and stages of clinical severity. All patients showed a positive discontinuous immunolabeling of utrophin on the sarcolemma, staining equally small and large muscle fibers, indicating that immature characteristics are maintained in such fibers. On Western blot, utrophin bands with concentrations 2- to 10-fold greater than in normal controls were detected in all DMD/BMD patients. However, no negative correlation was found between the amount of utrophin and the severity of clinical course, implying that the detectable utrophin levels in these patients did not compensate for dystrophin deficiency. In a DMD patient with growth hormone (GH) deficiency and a BMD-like clinical course, utrophin levels were comparable to the other typical DMD cases, which reinforces the hypothesis that the observed increase in utrophin is apparently not responsible for a milder clinical course in some patients with Xp21 muscular dystrophies. 35 refs., 2 figs., 1 tab.

  9. Ascitic microbiota composition is correlated with clinical severity in cirrhosis with portal hypertension.

    Full Text Available Identification of pathogenic bacteria in ascites correlates with poor clinical outcomes. Ascites samples are commonly reported culture-negative, even where frank infection is indicated. Culture-independent methods have previously reported bacterial DNA in ascites, however, whether this represents viable bacterial populations has not been determined. We report the first application of 16S rRNA gene pyrosequencing and quantitative PCR in conjunction with propidium monoazide sample treatment to characterise the viable bacterial composition of ascites. Twenty five cirrhotic patients undergoing paracentesis provided ascites. Samples were treated with propidium monoazide to exclude non-viable bacterial DNA. Total bacterial load was quantified by 16S rRNA Q-PCR with species identity and relative abundance determined by 16S rRNA gene pyrosequencing. Correlation of molecular microbiology data with clinical measures and diagnostic microbiology was performed. Viable bacterial signal was obtained in 84% of ascites samples, both by Q-PCR and pyrosequencing. Approximately 190,000 ribosomal pyrosequences were obtained, representing 236 species, including both gut and non gut-associated species. Substantial variation in the species detected was observed between patients. Statistically significant relationships were identified between the bacterial community similarity and clinical measures, including ascitic polymorphonuclear leukocyte count and Child-Pugh class. Viable bacteria are present in the ascites of a majority of patients with cirrhosis including those with no clinical signs of infection. Microbiota composition significantly correlates with clinical measures. Entry of bacteria into ascites is unlikely to be limited to translocation from the gut, raising fundamental questions about the processes that underlie the development of spontaneous bacterial peritonitis.

    Full Text Available We report the surgical technique and outcome of planned posterior assisted levitation (P-PAL in four cases of subluxated cataract. P-PAL was planned as the preferred approach in all cases. A spatula was inserted via the pars plana, the whole lens was lifted to the anterior chamber and then removed through a scleral tunnel incision. Anterior chamber intraocular lenses were implanted in all cases. All four eyes had severe subluxation of the crystalline lenses with marked phacodonesis. Two eyes had history of blunt trauma, and the other two eyes had severe pseudoexfoliation with spontaneous lens subluxation. Follow-up ranged from 1 to 2 years in three cases. The postoperative visual acuity was 20/80 or better. No intraoperative complications were observed. In conclusion, the P-PAL technique was successfully performed during cataract surgery in four eyes with severe subluxated cataracts. There were no complications over the long-term follow-up.

    Sickle cell disease (SCD) is a monogenic, yet highly phenotypically variable disease with multisystem pathology. This manuscript provides an overview of many of the known determinants, modifiers, and correlates of disease severity in SCD. Despite this wealth of data, modeling the variable and multisystem pathology of SCD continues to be difficult. The current status of prediction of specific adverse outcomes and global disease severity in SCD is also reviewed, highlighting recent successes and ongoing challenges. © 2016 by the Society for Experimental Biology and Medicine.

    Telomere shortening occurs with human aging in many organs and tissues and is accelerated by rapid cell turnover and oxidative injury. To clarify the clinical importance of telomere shortening in colonic mucosa in ulcerative colitis (UC), we measured average telomere length using quantitative real-time PCR in non-neoplastic colonic mucosa in UC patients and assessed its relationship to various clinical subtypes. Relative telomere length in genomic DNA was measured in colonic biopsies obtained from rectal inflammatory mucosa from 86 UC patients as well as paired non-inflammatory proximal colonic mucosae from 10 patients. Data were correlated with various clinical phenotypes. In paired samples, average relative telomere length of rectal inflammatory mucosa was shortened compared to normal appearing proximal colon in eight out of ten cases (p = 0.01). Telomere length shortening was significantly associated with more severe Mayo endoscopic subscore (p UC, reflecting severe inflammatory state in the colonic mucosa.

    Suicide-preventive training has shown to influence attitudes. This study aimed at investigating what impact other factors than knowledge might have on attitudes towards work with suicidal patients and suicide prevention. In 2007, 500 health-care staff working in a psychiatric clinic in Stockholm received a questionnaire with items concerning work with suicidal patients to which 358 (71.6%) responded. A set of attitude items were tested using structural equation modelling (LISREL). Three models were found to be satisfactory valid and reliable: Job clarity, Job confidence and Attitudes towards prevention. These were then used in regression analyses as dependent variables with predictors such as experience of work with suicidal patients, perceived sufficient training, age and gender. Perceived sufficient training was consistently the most important predictor for all three attitude concepts (p prevention). Age was another significant predictor for Job clarity (p suicide for Job confidence (p suicide preventive education is likely to improve attitudes towards the prevention of suicide, clarity and confidence regarding their role in the care for suicidal patients. These improvements may contribute to the prevention of suicide in health care settings.

    To review the nursing outcome, Fall Prevention Behavior, and clinically validate its indicators in people with stroke. A methodological study performed with 106 patients in two outpatient clinics, from July to September of 2013. Two pairs of trained nurses applied the NOC scale, one with and one without the use of operational definitions. The internal consistency, stability and difference between the medians obtained by nurses were compared within and between pairs. Most participants were men, elderly, with low education and income. Statistically significant differences were noted in twelve indicators. Five indicators had different means that were greater than the least significant difference. The indicators were statistically significant; the internal consistency was similar between the pairs and the intraclass correlation coefficient was more satisfactory in the pair that used the definitions. Thus, the construction of empirical referents and the clinical validation process makes the nursing indicators and outcomes more adequate for specific populations and provides an effective means to better evaluate the nursing actions.

    Advertising via Facebook to elicit involvement in clinical trials has demonstrated promise in expanding geographic reach while maintaining confidentiality. The purpose of this study is to evaluate Facebook advertising to reach at-risk, predominately African American or Black women in higher HIV prevalence communities for an HIV prevention clinical trial, and to compare baseline characteristics to those recruited on-the-ground. Maintaining confidentiality and the practical aspects of creating and posting ads on Facebook are described. The advertising strategy targeted multicultural affinities, gender, age, interest terms, and zip codes. We report on results during 205 days. A total of 516,498 Facebook users viewed the ads an average of four times, resulting in 37,133 clicks to the study website. Compared to 495 screened on-the-ground, 940 were screened via Facebook ads, of these, half (n = 477, 50.74%) were high risk, and of those at risk, 154 were randomized into the 6-month clinical trial. Black women comprised 71.60% (n = 673) of the total screened online. Roughly twice as many Black women screened via Facebook compared to on-the-ground, yet, the percentage at high risk was similar. Preliminary data suggest that the extent to which ad headlines and photos tap into authentic social experience, advertising on Facebook can extend geographic reach and provide a comparative sample to women recruited on-the-ground.

    Primary care physicians often do not use spirometry to confirm the diagnosis of chronic obstructive pulmonary disease. This project was designed to see how well physicians' impressions about their patients' chronic obstructive pulmonary disease severity correlate with the severity of airflow obstruction measured by spirometry and to assess whether spirometry results subsequently changed the physicians' opinions about chronic obstructive pulmonary disease severity and treatment. We performed a multicenter, cross-sectional, observational study conducted in 83 primary care clinics from across the United States. A total of 899 patients with a clinical diagnosis of chronic obstructive pulmonary disease completed a questionnaire and spirometry testing. Physicians completed a questionnaire and case report forms. Concordance among physician ratings, patient ratings, and spirometry results was evaluated. Physicians' chronic obstructive pulmonary disease severity ratings before spirometry were accurate for only 30% of patients with evaluable spirometry results, and disease severity in 41% of patients was underestimated. Physicians also underestimated severity compared with patients' self-assessment among 42% of those with evaluable results. After spirometry, physicians changed their opinions on the severity for 30% of patients and recommended treatment changes for 37%. Only 75% of patients performed at least 1 high-quality spirometry test; however, the physicians' opinions and treatment decisions were similar regardless of suboptimal test results. Without performing spirometry, physicians are likely to underestimate their patients' chronic obstructive pulmonary disease severity or inadequately characterize their patients' lung disease. Spirometry changed the physicians' clinical impressions and treatments for approximately one third of these patients; thus, spirometry is a valuable tool for chronic obstructive pulmonary disease management in primary care.

    Full Text Available Ventilator-associated pneumonia (VAP is one of the most commonly encountered hospital-acquired infections in intensive care units and is associated with significant morbidity and high costs of care. The pathophysiology, epidemiology, treatment and prevention of VAP have been extensively studied for decades, but a clear prevention strategy has not yet emerged. In this article we will review recent literature pertaining to evidence-based VAP-prevention strategies that have resulted in clinically relevant outcomes. A multidisciplinary strategy for prevention of VAP is recommended. Those interventions that have been shown to have a clinical impact include the following: (i Non-invasive positive pressure ventilation for able patients, especially in immunocompromised patients, with acute exacerbation of chronic obstructive pulmonary disease or pulmonary oedema, (ii Sedation and weaning protocols for those patients who do require mechanical ventilation, (iii Mechanical ventilation protocols including head of bed elevation above 30 degrees and oral care, and (iv Removal of subglottic secretions. Other interventions, such as selective digestive tract decontamination, selective oropharyngeal decontamination and antimicrobial-coated endotracheal tubes, have been tested in different studies. However, the evidence for the efficacy of these measures to reduce VAP rates is not strong enough to recommend their use in clinical practice. In numerous studies, the implementation of VAP prevention bundles to clinical practice was associated with a significant reduction in VAP rates. Future research that considers clinical outcomes as primary endpoints will hopefully result in more detailed prevention strategies.

    Full Text Available GATA binding protein 2 (GATA2 deficiency is a rare disorder of hematopoiesis, lymphatics, and immunity caused by spontaneous or autosomal dominant mutations in the GATA2 gene. Clinical manifestations range from neutropenia, lymphedema, deafness, to severe viral and mycobacterial infections, bone marrow failure, and acute myeloid leukemia. Patients also present with monocytopenia, dendritic cell, B- and natural killer (NK-cell deficiency. We studied the T-cell and NK-cell compartments of four GATA2-deficient patients to assess if changes in these lymphocyte populations could be correlated with clinical phenotype. Patients with more severe clinical complications demonstrated a senescent T-cell phenotype whereas patients with lower clinical score had undetectable changes relative to controls. In contrast, patients’ NK-cells demonstrated an immature/activated phenotype that did not correlate with clinical score, suggesting an intrinsic NK-cell defect. These studies will help us to determine the contribution of T- and NK-cell dysregulation to the clinical phenotype of GATA2 patients, and may help to establish the most accurate therapeutic options for these patients. Asymptomatic patients may be taken into consideration for hematopoietic stem cell transplantation when dysregulation of T-cell and NK-cell compartment is present.

    Full Text Available Background and objectives: Primary dysmenorrhea has remained a health problem. This study has compared the effect of oral and topical ginger on severity and duration of primary dysmenorrhea.  Methods: A single-blind randomized trial was conducted on 70 female students with moderate and severe primary dysmenorrhea. The participants were stratified randomized between two groups of oral and topical ginger. The oral group received 250 mg capsules of ginger powder and the topical group applied five drops of ginger oil topically every 6 hours from two days before through the first three days of menstruation for three cycles. The severity and duration of pain, and the number of mefenamic acid consumption were assessed in each cycle. Before-after changes were evaluated in each group and were compared between two groups. Results: The reduction of pain severity was 3(±3.2 in the topical compared to 2.6(±3.4 in the oral group (p

    Kenny Caffey syndrome (KCS) is a rare syndrome reported almost exclusively in Middle Eastern populations. It is characterized by severe growth retardation-short stature, dysmorphic features, episodic hypocalcaemia, hypoparathyroidism, seizures, and medullary stenosis of long bones with thickened cortices. We report a 10-year-old boy with KCS with an unusually severe respiratory and gastrointestinal system involvement-features not previously described in the literature. He had severe psychomotor retardation and regressed developmentally from walking unaided to sitting with support. MRI brain showed bilateral hippocampal sclerosis, marked supra-tentorial volume loss and numerous calcifications. A 12 bp deletion of exon 2 of tubulin-specific chaperone E (TBCE) gene was identified and the diagnosis of KCS was confirmed. Hypercarbia following a sleep study warranted nocturnal continuous positive airway pressure (CPAP) when aged 6. When boy aged 8, persistent hypercarbia with increasing oxygen requirement and increased frequency and severity of lower respiratory tract infections led to progressive respiratory failure. He became fully dependent on non-invasive ventilation and by 9 years he had a tracheotomy and was established on long-term ventilation. He developed retching, vomiting and diarrhea. Chest CT showed changes consistent with chronic aspiration, but no interstitial pulmonary fibrosis. He died aged 10 from respiratory complications.

    In everyday life there are many obstacles that prevent the creation of many important needs. They require a skillful adaptation and may be the cause of stress. Stress of considerable intensity can receive the joy of life and even lead to a temporary mental disorder. To present the main causes and frequency of disturbance determined according to the ICD-10 as a reaction to severe stress and adaptive disorders among patients in psychiatric and psychological counseling and to establish whether the causes of the disorder are dependent on factors such as age, sex or level of education. Analysis was done on a separate group of 754 persons from among patients seeking psychiatric counseling--Psychological Outpatient Mental Health in the 10th Military Clinical Hospital in Bydgoszcz, in 2005. This group were qualified person, who according to the criteria of ICD-10 were found to respond to severe stress and abnormal adaptation. In addition, during the interview determines whether they are long-term somatic illness. They have not been included in the study group. Also excluded persons who were found difficulties in operation prior to the stressful situation and those that have already been treated with psychiatric or psychological benefit from therapy. The collected data were statistically analyzed. The analysis identifies three main causes of adjustment disorder. The first group of reasons is related to difficulties in the workplace, which represents 59% of all patients with the disorder described. In this group identifies three major stressful situations: bullying, job loss, unemployment. Another reason relates to family problems. They are the reason for the emergence of abnormalities in 23% of patients analyzed group. Among these difficulties was divided into four main types of situation causing disorder presented. There are family conflicts, death of spouse, parent death, divorce. The last group of factors are stressful events or incidents which contributed to the

    Anti-MDA5 (Melanoma differentiation-associated gene 5) positive dermatomyositis is a new variant of clinically amyopathic dermatomyositis that presents with characteristic mucocutaneous findings and is associated with a higher risk of developing rapidly progressive interstitial lung disease. Because its presentation differs from that of classical dermatomyositis, this entity can be a diagnostic challenge for the clinician. We present the case of a 55-year-old male with a 7-month history of chill sensation, constitutional symptoms and polyarthralgia. Within 3 months, the patient developed progressive heart failure with dyspnoea and orthopnoea, together with characteristic cutaneous lesions. Skin biopsies demonstrated thrombosis of small and medium-sized arteries in the reticular dermis, together with an evolved lobular panniculitis and prominent mucin deposits. Clinicians should be aware of the characteristic clinical and histopathologic presentation of this variant of dermatomyositis to establish an early diagnosis. Further evidence is needed to clarify the risk of cardiac involvement in this subset of patients.

    Full Text Available Objective: To describe the clinical and epidemiological characteristics, evolution and to identify mortality factors associated in patients with SNP. Material and Methods: Descriptive study of a serie of cases of the Intensive Care Unit (ICU of a General Hospital. Medical records of patients which received medical attention and who meet the selection criteria were reviewed Results: Forty-one clinical records were evaluated. The average age was 69 old, predominantly male (68,3%. SNP was the reason of admission in 60.9% and 95.1% required mechanical ventilation. Hospital stay prior to diagnosis was 10 days, 65% of patients had some risk factor for multi resistence organisms, CPIS of entry was 9.3, cultures were positive in 39% of the cases and of these, 48.8% received proper antibiotic according to culture results. The days of stay in ICU were 20.6 days and 20 of the 41 medical records were for death patients. The clinical and epidemiological characteristics were similar between death and alive patients. An analysis of factors that could be associated with mortality SNP was made and it was found that for an age ≥ 70 years, the presence of any risk factor for multidrug resistence organism and control CPIS ≥ 6 were associated with higher mortality; while acquisition of the ICU was associated to lower mortality. Conclusions: The clinical, epidemiological characteristics and evolution of patients with SNP in our ICU were similar to those describe in the literature. Three factors associated with mortality in the ICU were identified.

    To evaluate the reliability, validity, and responsiveness of a new clinical asthma score, the Pediatric Asthma Severity Score (PASS), in children aged 1 through 18 years in an acute clinical setting. This was a prospective cohort study of children treated for acute asthma at two urban pediatric emergency departments (EDs). A total of 852 patients were enrolled at one site and 369 at the second site. Clinical findings were assessed at the start of the ED visit, after one hour of treatment, and at the time of disposition. Peak expiratory flow rate (PEFR) (for patients aged 6 years and older) and pulse oximetry were also measured. Composite scores including three, four, or five clinical findings were evaluated, and the three-item score (wheezing, prolonged expiration, and work of brea
