    Leukocyte concentration in blood is a classical marker of systemic inflammation. Whether high leukocyte counts are associated with incidence of heart failure (HF) is unknown. This population-based study explored whether the leukocyte concentrations were associated with incidence of hospitalizations due to HF. Leukocyte counts were measured in 16 940 men from the general population (mean age 44 years) without history of myocardial infarction or stroke. Incidence of hospitalizations due to HF (primary diagnosis) was monitored over 23 years of follow-up, in relation to quartiles of leukocytes. Subjects with myocardial infarction during follow-up were censored in the main analysis. During the follow-up, 436 men were hospitalized due to HF. Incidence of HF hospitalizations was increased in men with high leukocyte counts. After adjustments for confounding factors, the adjusted hazards ratio (HR, 95% CI) for HF hospitalization was 1.00 (reference), 1.26 (0.93 to 1.7), 1.24 (0.91 to 1.7), and 1.73 (1.3 to 2.3), respectively, for men with leukocytes in the 1st, 2nd, 3rd, and 4th (highest) quartiles (trend, Pleukocyte counts in middle-aged men were associated with increased long-term incidence of HF hospitalizations.

    Full Text Available Objectives: In this study, our aim was to evaluate and classify the voluntary error reports in the hospitals of Mashhad University of Medical Sciences. Patients have the right to receive health care in accordance to the best standards. Health care carries a risk of harm for patient safety, and with respect to today’s stressful systems with a large number of patients, it would be inevitable. The meaning of risk management is to predict adverse events and reduce their occurrence.Materials and Methods: A voluntary medical error reporting form was designed and approved by the clinical governance team of Mashhad Medical University. They were then distributed inside hospitals in the way in which everyone (health providers and patients could access them easily. The forms were collected and classified monthly in all wards. Classification was performed on the base of type, outcome and reporter. Data gathering took place from spring to autumn 2012. The data was analyzed by the SPSS software. Results: 2500 errors were extracted from 1000 voluntary error reporting forms of the 12 hospitals of Mashhad Medical University. The most frequent error type was treatment errors (36% related to drug administration, standard procedures and surgical events. Conclusions: Error reporting as a basic activity has an important role in discovering pitfalls of the health care system. To promote the reporting culture, its non punitive base must become clear for all professors and staff members, because this kind of reporting could lead to fewer medical errors and higher staff awareness about probable errors.

    Full Text Available Polar mesosphere summer echoes (PMSEs have been well studied using vertical incidence VHF radars at northern high-latitudes. In this paper, two PMSE events detected with the oblique incidence SuperDARN HF radars at Hankasalmi, Finland (62.3° N and Syowa Station, Antarctica (69.0° S, are analyzed, together with simultaneous VHF and medium-frequency (MF radar data. Altitude resolutions of the HF radars in the mesosphere and the lower thermosphere are too poor to know exact PMSE altitudes. However, a comparison of Doppler velocity from the HF radar and neutral wind velocity from the MF radar shows that PMSEs at the HF band appeared at altitudes within 80-90km, which are consistent with those from previous vertical incidence HF-VHF radar results. The HF-VHF PMSE occurrences exhibit a semidiurnal behavior, as observed by other researchers. It is found that in one event, PMSEs occurred when westward semidiurnal winds with large amplitude at 85-88km altitudes attained a maximum. When the HF-VHF PMSEs were observed at distances beyond 180km from MF radar sites, the MF radars detected no appreciable signatures of echo enhancement. Key words.

    Full Text Available ABSTRACT Objective: To evaluate the incidents spontaneously notified in a general hospital in Minas Gerais. Method: Retrospective, descriptive, quantitative study performed at a general hospital in Montes Claros - Minas Gerais State. The sample comprised 1,316 incidents reported from 2011 to 2014. The data were submitted to descriptive statistical analysis using Statistical Package for the Social Sciences version 18.0. Results: The prevalence of incidents was 33.8 per 1,000 hospitalizations, with an increase during the investigation period and higher frequency in hospitalization units, emergency room and surgical center. These occurred mostly with adult clients and relative to the medication supply chain. The main causes were noncompliance with routines/protocols, necessitating changes in routines and training. Conclusion: There was a considerable prevalence of incidents and increase in notifications during the period investigated, which requires the attention of managers and hospital staff. Nevertheless, we observed development of the patient safety culture.

    Full Text Available As terrorists attacks increase in frequency, hospital disaster plans need to be scrutinized to ensure that they take into account issues unique to weapons of mass destruction. This paper reports a review of the literature addressing hospital experiences with such incidents and the planning lessons thus learned. Construction of hospital disaster plans is examined as an ongoing process guided by the disaster planning committee. Hospitals are conceived as one of the components of a larger community disaster planning efforts, with specific attention devoted to defining important linkages among response organizations. This includes the public health authorities, political authorities, prehospital care agencies, and emergency management agencies. A review is completed of six special elements of weapons of mass destruction incidents that should be addressed in hospital disaster plans: incident command, hospital security, patient surge, decontamination, mental health consequences, and communications. The paper closes with a discussion of the importance of training and exercises in maintaining and improving the disaster plan.

    In November 2007, the Wisconsin Division of Public Health Hospital Disaster Preparedness Program State Expert Panel on Radiation Emergencies issued a report titled The Management of Patients in a Radiological Incident. Gundersen Lutheran Health System was selected to conduct a demonstration project to implement the recommendations in that report. A comprehensive radiological incident response plan was developed and implemented in the hospital's Trauma and Emergency Center, including the purchase and installation of radiation detection and identification equipment, staff education and training, a tabletop exercise, and three mock incident test exercises. The project demonstrated that the State Expert Panel report provides a flexible template that can be implemented at community hospitals using existing staff for an approximate cost of $25,000.

    Objective Describing the incidence of falls and its relation with preventive actions developed in a Brazilian university hospital. Method A retrospective longitudinal study. Hospitalized adult patients in the clinical, surgical, psychiatric and emergency units who suffered a fall in the institution, and who had the event notified in the period from January 2011 to December 2015 were included in the study. The data were collected from the institution's management information system and analyzed in the SPSS statistical program. Results There were 2,296 falls, with a mean incidence of 1.70 falls/1,000 patients per day. An increase in the incidence of falls was observed in the period from 2011 (1.61) to 2012 (2.03). In the following years, the incidence of falls decreased from 1.83 falls/1,000 patients per day in 2013 to 1.42 falls/1,000 patients per day in 2015. The incidence of falls accompanied an implementation of preventive actions, suggesting the impact of such interventions in reducing the event occurrence. Conclusion The findings demonstrate the importance of implementing preventive interventions in reducing the incidence of falls in hospitalized patients.

    In patients hospitalized with acutely decompensated heart failure, unresolved signs and symptoms of fluid overload have been consistently associated with poor outcomes. Regardless of dosing and type of administration, intravenous loop diuretics have not reduced heart failure events or mortality in patients with acutely decompensated heart failure. The results of trials comparing intravenous loop diuretics to mechanical fluid removal by isolated venovenous ultrafiltration have yielded conflicting results. Studies evaluating early decongestive strategies have shown that ultrafiltration removed more fluid and was associated with fewer heart failure-related rehospitalization than intravenous loop diuretics. In contrast, when used in the setting of worsening renal function, ultrafiltration was associated with poorer renal outcomes and no reduction in heart failure events. The AVOID-HF trial seeks to determine if an early strategy of ultrafiltration in patients with acutely decompensated heart failure is associated with fewer heart failure events at 90 days compared with a strategy based on intravenous loop diuretics. Study subjects from 40 highly experienced institutions are randomized to either early ultrafiltration or intravenous loop diuretics. In both treatment arms, fluid removal therapies are adjusted according to the patients' hemodynamic condition and renal function. The study was unilaterally terminated by the sponsor in the absence of futility and safety concerns after the enrollment of 221 subjects, or 27% of the originally planned sample size of 810 patients. The AVOID-HF trial's principal aim is to compare the safety and efficacy of ultrafiltration vs that of intravenous loop diuretics in patients hospitalized with acutely decompensated heart failure. Because stepped treatment approaches are applied in both ultrafiltration and intravenous loop diuretics groups and the primary end point is time to first heart failure event within 90 days, it is hoped that

    Aging of the patient population has led to increased occurrence of accidental falls in acute care settings. The aim of this study is to survey the annual occurrence of falls in a university hospital, and to examine procedures to prevent fall. A total of 49,059 inpatients were admitted to our hospital from April 2015 to March 2016. A fall assessment scale was developed to estimate the risk of fall at admission. Data on falls were obtained from the hospital incident reporting system. There were fall-related incidents in 826 patients (1.7%). Most falls occurred in hospital rooms (67%). Adverse events occurred in 101 patients who fell (12%) and were significantly more frequent in patients aged ≥80 years old and in those wearing slippers. The incidence of falls was also significantly higher in patients in the highest risk group. These results support the validity of the risk assessment scale for predicting accidental falls in an acute treatment setting. The findings also clarify the demographic and environmental factors and consequences associated with fall. These results of the study could provide important information for designing effective interventions to prevent fall in elderly patients.

    Heart failure (HF) is common in long-term care facilities (LTCs). This study compared mortality and hospitalization rates and examined predictors of these outcomes among new LTC residents with and without HF. This prospective cohort study followed 546 newly admitted residents from 42 LTCs for up to 1 year. Health information was collected from participant and caregiver interviews, physicians' records, diagnostic procedures, and hospitalization records. Multivariate logistic regression modeling determined predictors of hospitalization among residents, and Cox proportional hazards regression determined predictors for time to mortality. HF prevalence was 21.4%. The sample was predominantly (>70%) female, and individuals with HF were significantly older with higher prevalence of reduced left ventricular ejection fraction. Overall annual mortality and hospitalization rates were 24% and 27%, respectively. Among residents with HF, 42% died and 31% were hospitalized within 1 year. Among residents with HF, use of major tranquilizers was the strongest predictor of sooner mortality; use of anticoagulants and major tranquilizers also increased mortality risk, whereas higher baseline function was associated with longer time to mortality. History of peripheral vascular disease was the strongest predictor of hospitalizations among residents with HF, and use of antiplatelet agents and history of any smoking exposure increased this risk. Among LTC residents, HF is associated with high mortality and hospitalization rates. Many factors contribute to mortality and hospitalizations among residents with HF, and comprehensive HF management programs are needed to improve outcomes. Copyright © 2013 Elsevier Inc.

    2017-04-01

    Venous thromboembolism (VTE) is a major cause of preventable morbidity and mortality in hospitalized patients. In spite of guidelines, VTE prophylaxis continues to be underutilised, and hospital acquired thrombosis (HAT) continues to be a problem. This study was conducted to estimate the incidence of HAT in a tertiary referral centre and to examine whether VTE risk assessment and thromboprophylaxis (TP) were implemented. Patients 18 years and above, with a radiologically-confirmed acute VTE during the study period of 15 weeks were included. Acute VTE was diagnosed in 100 patients and HAT was diagnosed in 48. There were 12,024 admissions over the study period, therefore the incidence of HAT was 0.4%. TP was prescribed in only 35% of patients, and 65% did not receive any or appropriate TP. Hospitals without active implementation of a formal risk assessment tool and TP policy are likely to continue to have increased incidence of HAT.

    Effectiveness of hospital management of disasters requires a well-defined and rehearsed system. The Hospital Incident Command System (HICS), as a standardized method for command and control, was established in Iranian hospitals, but it has performed fairly during disaster exercises. This paper describes the process for, and modifications to HICS undertaken to optimize disaster management in hospitals in Iran. In 2013, a group of 11 subject matter experts participated in an expert consensus modified Delphi to develop modifications to the 2006 version of HICS. The following changes were recommended by the expert panel and subsequently implemented: 1) A Quality Control Officer was added to the Command group; 2) Security was defined as a new section; 3) Infrastructure and Business Continuity Branches were moved from the Operations Section to the Logistics and the Administration Sections, respectively; and 4) the Planning Section was merged within the Finance/Administration Section. An expert consensus group developed a modified HICS that is more feasible to implement given the managerial organization of hospitals in Iran. This new model may enhance hospital performance in managing disasters. Additional studies are needed to test the feasibility and efficacy of the modified HICS in Iran, both during simulations and actual disasters. This process may be a useful model for other countries desiring to improve disaster incident management systems for their hospitals.

    Patterns of medical resource use near the end of life may differ across modes of death. The aim of this study was to characterize patterns of inpatient resource use and direct costs for patients with heart failure (HF) who died of sudden cardiac death (SCD), HF, other cardiovascular causes, or noncardiovascular causes during the last year of life. Data were from a randomized trial of exercise training in patients with HF. Mode of death was adjudicated by an end point committee. Generalized estimating equations were used to compare hospitalizations, inpatient days, and inpatient costs incurred during the final year of life in patients who died of different causes, adjusting for clinical and treatment characteristics. Of 2,331 patients enrolled in the trial, 231 died after ≥1 year of follow-up with an adjudicated mode of death, including 72 of SCD, 80 of HF, 34 of other cardiovascular causes, and 45 of noncardiovascular causes. Patients who died of SCD were younger, had less severe HF, and incurred fewer hospitalizations, fewer inpatient days, and lower inpatient costs than patients who died of other causes. After adjustment for patient characteristics, inpatient resource use varied by 2 to 4 times across modes of death, suggesting that cost-effectiveness analyses of interventions that reduce mortality from SCD compared to other causes should incorporate mode-specific end-of-life costs. In conclusion, resource use and associated medical costs in the last year of life differed markedly in patients with HF who experienced SCD and patients who died of other causes.

    To determine the incidence, etiology and outcome of Cardiorenal syndrome (CRS) in hospitalized children. A prospective cohort study was carried out in 242 children between 6 mo to 18 y of age hospitalized with primary cardiac, renal or any systemic disorder at a tertiary care center in India. The primary outcome was the development of CRS. Univariate and multivariate logistic regression analysis were performed to determine the risk of mortality secondary to CRS. Among 242 children, 67 (27.7%) children developed CRS and the rest 175 (72.3%) did not. Among those with CRS, 40.3%, 20.9%, and 38.8% had CRS-1, 3 and 5, respectively. Cardiac diseases leading to CRS were myocarditis (40.7%) followed by congenital heart disease (25.9%), rheumatic heart disease (18.5%), and dilated cardiomyopathy (7.4%); renal disease associated with CRS was acute glomerulonephritis (100%) and major systemic disorders leading to CRS were septicemia (53.8%), malaria (23.1%), scrub typhus (7.7%), and acute gastroenteritis (3.8%). The occurrence of CRS was associated with an increased risk of mortality (OR 6.3, 95% CI: 2.8, 14.1; p 0.000). A subgroup analysis revealed that children with CRS having acute kidney injury stage 2 and 3 also had a higher risk of mortality (p 0.001). The incidence of CRS is quite high in children with cardiac, renal or systemic diseases and is associated with a significant risk of mortality. Children presenting with these illnesses should be monitored for the occurrence of CRS so that early intervention may reduce mortality.

    To evaluate the evolution of falls with the implemented measures to improve the attention of patients at risk and to reduce the number of falls. To know the characteristics of patients who have suffered fall-related injuries. All the falls registered between 2008 and 2013 have been analyzed to determine the evolution of these and to describe the implemented measures through the electronic clinical history at University Hospital of Fuenlabrada. The incidence of falls in hospitalized patients has been estimated and the evolution with the chi square test has been studied. The frequencies of the characteristics of patients who fall has been presented: age, length of stay, performed activity, patient companion, mobility level, state of consciousness. 445 registered falls happened. 2009 is the year with the highest number of falls, 86 patients fell of a total of 15,819 discharged patients (0.55%). The statistic drops until 2013, where 55 patients fell out of 15,052 discharged patients (0.37%). This difference was not statistically significant. The deployment of an assessment about fall risk at admission has helped to identify individualized risk factors. Furthermore, the awareness and alerts to the nursing staff have helped to consider fall prevention as a rutinary procedure, hence appropriate measures can be implemented on the most vulnerable patients.

    Importance It remains unclear whether telemonitoring approaches provide benefits for patients with heart failure (HF) after hospitalization. Objective To evaluate the effectiveness of a care transition intervention using remote patient monitoring in reducing 180-day all-cause readmissions among a broad population of older adults hospitalized with HF. Design, Setting, and Participants We randomized 1437 patients hospitalized for HF between October 12, 2011, and September 30, 2013, to the intervention arm (715 patients) or to the usual care arm (722 patients) of the Better Effectiveness After Transition–Heart Failure (BEAT-HF) study and observed them for 180 days. The dates of our study analysis were March 30, 2014, to October 1, 2015. The setting was 6 academic medical centers in California. Participants were hospitalized individuals 50 years or older who received active treatment for decompensated HF. Interventions The intervention combined health coaching telephone calls and telemonitoring. Telemonitoring used electronic equipment that collected daily information about blood pressure, heart rate, symptoms, and weight. Centralized registered nurses conducted telemonitoring reviews, protocolized actions, and telephone calls. Main outcomes and measures The primary outcome was readmission for any cause within 180 days after discharge. Secondary outcomes were all-cause readmission within 30 days, all-cause mortality at 30 and 180 days, and quality of life at 30 and 180 days. Results Among 1437 participants, the median age was 73 years. Overall, 46.2% (664 of 1437) were female, and 22.0% (316 of 1437) were African American. The intervention and usual care groups did not differ significantly in readmissions for any cause 180 days after discharge, which occurred in 50.8% (363 of 715) and 49.2% (355 of 722) of patients, respectively (adjusted hazard ratio, 1.03; 95% CI, 0.88-1.20; P = .74). In secondary analyses, there were no significant differences in 30-day

    Full Text Available Abstract Background Acute seizures are common among children admitted to hospitals in resource poor countries. However, there is little data on the burden, causes and outcome of neonatal seizures in sub-Saharan Africa. We determined the minimum incidence, aetiology and immediate outcome of seizures among neonates admitted to a rural district hospital in Kenya. Methods From 1st January 2003 to 31st December 2007, we assessed for seizures all neonates (age 0-28 days admitted to the Kilifi District Hospital, who were resident in a defined, regularly enumerated study area. The population denominator, the number of live births in the community on 1 July 2005 (the study midpoint was modelled from the census data. Results Seizures were reported in 142/1572 (9.0% of neonatal admissions. The incidence was 39.5 [95% confidence interval (CI 26.4-56.7] per 1000 live-births and incidence increased with birth weight. The main diagnoses in neonates with seizures were sepsis in 85 (60%, neonatal encephalopathy in 30 (21% and meningitis in 21 (15%, but only neonatal encephalopathy and bacterial meningitis were independently associated with seizures. Neonates with seizures had a longer hospitalization [median period 7 days - interquartile range (IQR 4 to10] -compared to 5 days [IQR 3 to 8] for those without seizures, P = 0.02. Overall, there was no difference in inpatient case fatality between neonates with and without seizures but, when this outcome was stratified by birth weight, it was significantly higher in neonates ≥ 2.5 kg compared to low birth weight neonates [odds ratio 1.59 (95%CI 1.02 to 2.46, P = 0.037]. Up to 13% of the surviving newborn with seizures had neurological abnormalities at discharge. Conclusion There is a high incidence of neonatal seizures in this area of Kenya and the most important causes are neonatal encephalopathy and meningitis. The high incidence of neonatal seizures may be a reflection of the quality of the perinatal and

    Incidents in health care happen every now and then. Incidents are often extensively covered by the news media. In this study, we investigated the impact of an incident in a Dutch hospital on public trust in health care in the population living in the vicinity of where the incident took place and in the national population. News media coverage of the incident started in Fall 2008. We collected data in three samples, using a postal questionnaire on public trust in health care. Two samples were a cross-section of the Dutch population; one was questioned in October 2006 and the other in October 2008. The third sample, also questioned in October 2008, consisted of 1000 people living in the surrounding area of the hospital where the incident occurred. The cross-sectional sample of October 2006 was a reference group, and at that time no incidents in health care were covered in the media. In the local population, the incident had a strong impact on public trust in the hospital and among the specialists working there. Also, in the local population, the impact of the incident was generalized to trust in hospitals and specialists in general. In the national population, no impact of the incident on the public's trust was found, despite national news media coverage. Local incidents have an impact on public trust in health care in the local population. However, these incidents do not influence public trust in health care in the national population.

    This study sought to measure the impact on all-cause death or readmission of adding center-based exercise training (ET) to disease management programs for patients with a recent acute heart failure (HF) hospitalization. ET is recommended for patients with HF, but evidence is based mainly on ET as a single intervention in stable outpatients. A randomized, controlled trial with blinded outcome assessor, enrolling adult participants with HF discharged from 5 hospitals in Queensland, Australia. All participants received HF-disease management program plus supported home exercise program; intervention participants were offered 24 weeks of supervised center-based ET. Primary outcome was all-cause 12-month death or readmission. Pre-planned subgroups included age (40%), and exercise adherence. Between May 2008 and July 2013, 278 participants (140 intervention, 138 control) were enrolled: 98 (35.3%) age ≥70 years, 71 (25.5%) females, and 62 (23.3%) with a left ventricular ejection fraction of >40%. There were no adverse events associated with ET. There was no difference in primary outcome between groups (84 of 140 [60.0%] intervention vs. 90 of 138 [65.2%] control; p = 0.37), but a trend toward greater benefit in participants age management programs with supported home exercise in patients recently hospitalized with acute HF, but did not reduce combined end-point of death or readmission. (A supervised exercise programme following hospitalisation for heart failure: does it add to disease management?; ACTRN12608000263392).

    Incident reporting is the prevailing approach to gathering data on accidental falls in hospitals for both research and quality assurance purposes, though is of questionable quality as staff time pressures, perception of blame and other factors are thought to contribute to under-reporting. This research aimed to identify contextual factors influencing recording of in-hospital falls on incident reports. A qualitative multi-centre investigation using an open written response questionnaire was undertaken. Participants were asked to describe any factors that made them feel more or less likely to record a fall on an incident report. 212 hospital staff from 30 wards in 7 hospitals in Queensland, Australia provided a response. A framework approach was employed to identify and understand inter-relationships between emergent categories. Three main categories were developed. The first, determinants of reporting, describes a hierarchical structure of primary (principle of reporting), secondary (patient injury), and tertiary determinants that influenced the likelihood that an in-hospital fall would be recorded on an incident report. The tertiary determinants frequently had an inconsistent effect. The second and third main categories described environmental/cultural facilitators and barriers respectively which form a background upon which the determinants of reporting exists. A distinctive framework with clear differences to recording of other types of adverse events on incident reports was apparent. Providing information to hospital staff regarding the purpose of incident reporting and the usefulness of incident reporting for preventing future falls may improve incident reporting practices.

    Heart failure (HF) is a major public health problem affecting predominantly older adults. Nonadherence to diet remains a significant contributor to acute decompensated HF (ADHF). The sodium-restricted Dietary Approaches to Stop Hypertension (DASH/SRD) eating plan reduces cardiovascular dysfunction that can lead to ADHF and is consistent with current HF guidelines. We propose that an intervention that promotes adherence to the DASH/SRD by home-delivering meals will be safe and improve health-related quality of life (QOL) in older adults after hospitalization for ADHF. This is a 3-center, randomized, single-blind, controlled trial of 12-week duration designed to determine the safety and efficacy of home-delivered DASH/SRD-compliant meals in older adults after discharge from ADHF hospitalization. Sixty-six subjects will be randomized in a 1:1 stratified fashion by gender and left ventricular ejection fraction (DASH/SRD-compliant meals or usual dietary advice for 4weeks after hospital discharge. Investigators will be blinded to group assignment, food diaries, and urinary electrolyte measurements until study completion. The primary efficacy end point is the change in the Kansas City Cardiomyopathy Questionnaire summary scores for health-related QOL from study enrollment to 4weeks postdischarge. Safety evaluation will focus on hypotension, renal insufficiency, and hyperkalemia. Exploratory end points include echocardiography, noninvasive vascular testing, markers of oxidative stress, and salt taste sensitivity. This randomized controlled trial will test the efficacy, feasibility, and safety of 4weeks of DASH/SRD after ADHF hospitalization. By testing a novel dietary intervention supported by multiple levels of evidence including preliminary data in outpatients with stable HF, we will address a critical evidence gap in the care of older patients with ADHF. If effective and safe, this intervention could be scaled to assess effects on readmission and healthcare costs in

    2009-01-01

    Background A hospital's capacity and preparedness is one of the important parts of disaster planning. Hospital-related incidents, a new phenomenon in Swedish healthcare, may lead to ambulance diversions, increased waiting time at emergency departments and treatment delay along with deterioration of disaster management and surge capacity. We aimed to identify the causes and impacts of hospital-related incidents in Region Västra Götaland (western region of Sweden). Methods The regional registry at the Prehospital and Disaster Medicine Center was reviewed (2006–2008). The number of hospital-related incidents and its causes were analyzed. Results There were an increasing number of hospital-related incidents mainly caused by emergency department's overcrowdings, the lack of beds at ordinary wards and/or intensive care units and technical problems at the radiology departments. These incidents resulted in ambulance diversions and reduced the prehospital capacity as well as endangering the patient safety. Conclusion Besides emergency department overcrowdings, ambulance diversions, endangering patient s safety and increasing risk for in-hospital mortality, hospital-related incidents reduces and limits the regional preparedness by minimizing the surge capacity. In order to prevent a future irreversible disaster, this problem should be avoided and addressed properly by further regional studies. PMID:19493330

    Full Text Available Objectives: This study aimed to investigate the incidence of pterygium in a particular district of Istanbul, its association with age, and gender, and the severity of the disease. Methods: All patients aged ≥ 30 years referred to our outpatient clinics between January 2009 and December 2009 were included in this retrospective study. Age, gender, anterior segment photos, and findings of biomicroscopic eye examination were evaluated. Results: The incidence of pterygium for all age groups was 2.91% (male 1.75%, female 3.67% with an increasing incidence with age. A significant difference was detected in its incidence favoring female patients in 40-49, and 70-79, and male patients in ≥ 80 age groups, respectively. In addition, pterygium was seen in one (75.4% or both eyes (24.6% preferring right or left eye in 50.7%, and 49.3% of the patients, respectively. Pterygium was in nasal or temporal region in 98%, and 2% of the patients, respectively. The disease state in 59.9% of the patients was consistent with Stage 2 pterygium. The distance of pterygium from limbus was observed greatest in 60-69, and at a minimum in 40-49 age groups. No relationship was found between eye colour and development of pterygium. Conclusion: The incidence of pterygium increases with age. Incidence of pterygium differs between genders but without any significant difference. Its occurrence in one or both eyes and in right and left eyes was not influenced by gender of the patients. A statistically significant impact of eye colour of the patient on the development of pterygium was not disclosed. J Clin Exp Invest 2013; 4 (4: 436-442

    To determine if and in what ways serious patient safety incidents differ from nonserious patient safety incidents. Statistical analysis was performed on patient safety incident reports that were reported in 2015 in Finland's largest hospital district (Helsinki and Uusimaa, HUS). Reports were divided into two groups: nonserious incidents and serious incidents. Differences between groups were studied from several types of categorically divided information. Of the total number of reports (15,863), 1% were serious incidents (175). Serious and nonserious incidents differed significantly from each other. Serious incidents concerning laboratory, imaging, or medical equipment were more common. On the other hand, incidents concerning medication, infusion, and blood transfusion were less frequent. In serious incidents, the proportion of doctors reporting was greater, and contributing factors were better recognized, the most common being working of procedures. In the future, special attention should be given to the particular aspects of serious patient safety incidents, such as safe use of medical equipment, training, and handling of procedures. Root cause analysis is an effective way to handle serious incidents and enables the prevention of their reoccurrence. However, a systematic follow-up of the root cause analysis should be developed. © 2018 American Society for Healthcare Risk Management of the American Hospital Association.

  1. Hospitalizations Due to Unstable Angina Pectoris in Diastolic and Systolic Heart Failure

    2008-01-01

    Patients with diastolic heart failure (HF) i.e. clinical HF with normal or near normal left ventricular ejection fraction (LVEF) may experience unstable angina pectoris (UAP) due to epicardial atherosclerotic coronary artery disease (CAD) and/or to subendocardial ischemia, even in the absence of CAD. However, the risk of UAP among ambulatory diastolic HF patients has not been well studied. We examined incident hospitalizations due to UAP among 916 diastolic HF (LVEF >45%) patients without significant valvular heart disease and 6800 systolic HF (LVEF ≤45%) patients in the Digitalis Investigation Group trial. During a 38-month median follow-up, 12% (797/6,800) of systolic HF patients (incidence rate, 435/10,000 person-years) and 15% (138/916) of diastolic HF patients (incidence rate, 536/10,000 person-years) were hospitalized for UAP (adjusted hazard ratio for diastolic HF, 1.22; 95% confidence interval, 1.02–1.47; p=0.032). There was a graded increase in incident hospital admissions for UAP with increasing LVEF. Hospitalizations for UAP occurred in 11% (520/4,808; incidence rate, 407/10,000 person-years), 14% (355/2556; incidence rate, 496/10,000 person-years) and 17% (60/352; incidence rate, 613/10,000 person-years) of HF patients, respectively, with LVEF 55%. Compared with HF patients with LVEF 55% were respectively 1.17 (1.02–1.34; p=0.028) and 1.57 (1.20–2.07; p=0.026). In conclusion, in ambulatory chronic HF patients, higher LVEF was associated with increased risk of hospitalizations due to UAP. As in patients with systolic HF, those with diastolic HF should be routinely evaluated for myocardial ischemia and managed accordingly. PMID:17293184

    2014-07-01

    During April 2007-April 2010, surveillance physicians in adult and pediatric medicine wards of three tertiary public hospitals in Bangladesh identified patients who developed hospital-acquired diarrhea. We calculated incidence of hospital-acquired diarrhea. To identify risk factors, we compared these patients to randomly selected patients from the same wards who were admitted > 72 hours without having diarrhea. The incidence of hospital-acquired diarrhea was 4.8 cases per 1,000 patient-days. Children diarrhea than older children. The risk of developing hospital-acquired diarrhea increased for each additional day of hospitalization beyond 72 hours, whereas exposure to antibiotics within 72 hours of admission decreased the risk. There were three deaths among case-patients; all were infants. Patients, particularly young children, are at risk for hospital-acquired diarrhea and associated deaths in Bangladeshi hospitals. Further research to identify the responsible organisms and transmission routes could inform prevention strategies. © The American Society of Tropical Medicine and Hygiene.

    It is reported on an epidemic of hepatitis B of 29 patients in a district hospital. Due to diagnostic errors in importation and a more frequent appearance of diseases of hepatitis B in the surgical department and the 2nd medical department, in which above all diabetics are treated, took place. The average age of the patients was 55 years. In all patients the clinical course was to be regarded as severe. 4 of 29 patients died. In all patients the hepatitis B disease showed a pronounced jaundice with high transaminases, particularly the SGOT and LAP were clearly increased. Also the duration of the presence was longer than in hepatitis A as well as the transition into chronic hepatitis was more frequent. By diagnostic information of the physicians and the other medical staff as well as improved measures of desinfection the epidemic could be restricted.

    The aim of this study was to test the association between the rates of patient-reported incidents and patient harm documented in the patient record. The study was a secondary analysis of two national hospital assessments conducted in 2011. Hospital services in Norway. The patient survey was a standard national patient-experience survey conducted at the hospital level for all 63 hospitals in Norway. The medical record review was performed by 47 Global Trigger Tools (GTTs) in all 19 hospital trusts and 4 private hospitals. The two data sets were matched at the unit level, yielding comparable patient experiences and GTT data for 7 departments, 16 hospitals and 11 hospital trusts. No intervention. The correlation at the unit level between the patient-reported incident in hospital instrument (PRIH-I) and estimated rates of patient harm from the GTT. The PRIH-I index was significantly correlated with all patient-reported experience indicators at the individual level, with estimates for all patient harm events (Categories E-I) at the unit level (r = 0.62, P < 0.01), and with estimates of more serious harm events in Categories F-I (r = 0.42, P < 0.05). Patient-reported incidents in hospitals, as measured by the PRIH-I, are strongly correlated with patient harm rates based on the GTT. This indicates that patient-reported incidents are related to patient safety, but more research is needed to confirm the usefulness of patient reporting in the evaluation of patient safety. © The Author 2014.

    Incidence of multi-resistant bacteria is an indicator that permits better estimation of the magnitude of bacterial resistance in hospitals. To evaluate the incidence of relevant multi-drug resistant bacteria in intensive care units (ICUs) of Chile. Participating hospitals submitted information about the number of isolates from infected or colonized patients with 7 epidemiologically relevant multi-resistant bacteria in adult and pediatric ICUs between January 1, 2014 and October 31, 2015 and the number of bed days occupied in these units in the same period was requested. With these data incidence was calculated per 1,000 patient days for each unit. Information from 20 adults and 9 pediatric ICUs was reviewed. In adult ICUs the bacteria with the highest incidence were K. pneumoniae ESBL [4.72 × 1,000 patient day (1.21-13.89)] and oxacillin -resistant S. aureus [3.85 (0.71-12.66)]. In the pediatric units the incidence was lower, highlighting K. pneumoniae ESBL [2.71 (0-7.11)] and carbapenem -resistant P. aeruginosa [1.61 (0.31-9.25)]. Important differences between hospitals in the incidence of these bacteria were observed. Incidence of multi-resistant bacteria in adult ICU was significantly higher than in pediatric ICU for most of the studied bacterias.

    Full Text Available BACKGROUND Ocular trauma is a major cause of preventable ocular blindness in the world. The present available data represents the tip of iceberg. The data pertaining to ocular trauma is just hospital based data which does not accurately represent the population at risk. The ocular morbidity may be disproportionate to the severity of injury. Though eyes represent only 0.21% of body surface area and 4% of facial area, they are the third most common trauma exposed areas after hands and feet. MATERIALS AND METHODS Our study group consisted of 341 patients who attended ophthalmology OPD with history of ocular trauma of whom 221 were males and 121 were females. The study was conducted over a period of one year. A complete anterior and posterior segment evaluation of all the patients was done. Other accessory ocular and systemic investigations wherever essential were done. RESULTS The ocular trauma was more common in males (64.52% predominantly affecting patients of 20-40 years age group (36.07%. Most often the injuries were occupation related (73.90% and the most common work related injury observed was extraocular foreign body in 134 patients (39.29%. Closed globe injuries were more common as compared to open globe injuries. Eyes with better visual acuity at presentation had better visual prognosis. Blinding trauma was observed in 29 patients (8.50%. CONCLUSION Ocular injuries are more commonly occupation related and mostly effect young males who are the main work force of our society. Stringent implementation of preventive norms in industries to all the workers and safety precautions during sports, driving need to be enforced.

    Full Text Available Background: Applying an effective management system in emergency incidents provides maximum efficiency with using minimum facilities and human resources. Hospital Emergency Incident Command System (HEICS is one of the most reliable emergency incident command systems to make hospitals more efficient and to increase patient safety. This research was to study requirements, barriers, and strategies of HEICS in hospitals affiliated to Isfahan University of Medical Sciences (IUMS. Methods: This was a qualitative research carried out in Isfahan Province, Iran during 2008-09. The study population included senior hospital managers of IUMS and key informants in emergency incident management across Isfahan Province. Sampling method was in non-random purposeful form and snowball technique was used. The research in-strument for data collection was semi-structured interview; collected data was analyzed by Colaizzi Technique. Results: Findings of study were categorized into three general categories including requirements (organizational and sub-organizational, barriers (internal and external of HEICS establishment, and providing short, mid and long term strategies. These categories are explained in details in the main text. Conclusions: Regarding the existing barriers in establishment of HEICS, it is recommended that responsible authori-ties in different levels of health care system prepare necessary conditions for implementing such system as soon as possible via encouraging and supporting systems. This paper may help health policy makers to get reasonable frame-work and have comprehensive view for establishing HEICS in hospitals. It is necessary to consider requirements and viewpoints of stakeholders before any health policy making or planning.

    The aim of this study was to evaluate the effectiveness and sustainability of educational interventions to encourage incident reporting. This was a quasi-experimental design. The study involved nurses working in two gastroenterology surgical wards at Fukuoka University Hospital, Japan. The number of participants on each ward was 26 nurses at baseline. For the intervention group, we provided 15 minutes of education about patient safety and the importance of incident reporting once per month for six months. After the completion of the intervention, we compared incident reporting in the subsequent 12 months for both groups. Questionnaires about reasons/motives for reporting were administered three times, before the intervention, after the intervention, and six months after the intervention for both the intervention group and the control group. For the intervention group, incident reporting during the 6 months after the intervention period increased significantly compared with the baseline. During the same period, the reasons and motives for reporting changed significantly in the intervention group. The increase in reported incidents during the 6- to 12-month period following the intervention was not significant. In the control group, there was no significant difference during follow-up compared with the baseline. A brief intervention about patient safety changed the motives for reporting incidents and the frequency of incidents reported by nurses working in surgical wards in a university hospital in Japan. However, the effect of the education decreased after six months following the education. Regular and long-term effort is required to maintain the effect of education.

    Analysis of critical incidents provides valuable information to improve the quality and safety of patient care. This study identified and analyzed pediatric anesthesia-related critical incidents including cardiac arrests in a tertiary teaching children's hospital. All pediatric anesthesia-related critical incidents reported in a voluntary departmental reporting system between January 2008 and August 2013 were included in the analysis. A critical incident was defined as (i) any incident that altered patients' vital signs and affected the management of patients while they were under the care of an anesthesiologist, and (ii) human factor: where patient injury or accidents were as a result of human error. Changes in vital signs that recovered spontaneously were excluded. During the 6-year study period, a total of 229 critical incidents were reported from 49,373 anesthetic procedures. The most frequently reported incidents were associated with the respiratory system (55%), with tracheal tube-related events accounting for 40.9% of respiratory incidents followed by laryngospasm (17.3% of respiratory incidents). Cardiac arrest occurred in 42 cases in this study (8.5 cases per 10,000 anesthetics). Cardiovascular problems were the major causes of cardiac arrest (66.7%), and incidents of cardiogenic shock and hemorrhage/hypotension contributed equally to the cardiac arrest induced by cardiovascular problems (each 16.7%). Human factor-related events accounted for 58.5% of all critical incidents of which 53.7% were respiratory events. Despite recent improvements in safety of pediatric anesthesia, many preventable factors still remain that can lead to critical incidents. © 2016 John Wiley & Sons Ltd.

    To identify the most common errors and adverse events and their contributing factors among the older patients admitted to hospital and examine recommendations from an expert review panel for prevention and reduction of the adverse events. Older patients are at an increased risk of errors and adverse events while hospitalized. The increasing evidence suggests that understanding the risks factors that contribute to these errors and adverse events facilitates the education of health professionals and the reduction and preventions of the harm. A retrospective audit of the Incident Information Management System and Root Cause Analysis databases from July 1, 2005, to June 30, 2006, was undertaken in 1 large tertiary metropolitan hospital in New South Wales, Australia. Of the 643 incidents identified, falls (n = 309), medication errors (n = 136), and clinical management (n = 104) were the most common errors among older patients, and the failure of clinicians to follow policies and procedures and poor communication between clinicians contributed to these incidents. Although systems are in place for incident reporting and analysis of the contributing factors, improvement depends upon clinicians taking responsibility for anticipating and moderating risk using previous data to identify system weaknesses and monitoring improvements especially in hospitalized older patients.

    Hospitals are cornerstones for health care in a community and must continue to function in the face of a disaster. The Hospital Incident Command System (HICS) is a method by which the hospital operates when an emergency is declared. Hospitals are often ill equipped to evaluate the strengths and vulnerabilities of their own management systems before the occurrence of an actual disaster. The main objective of this study was to measure the decision making performance according to HICS job actions sheets using tabletop exercises. This observational study was conducted between May 1st 2008 and August 31st 2009. Twenty three Iranian hospitals were included. A tabletop exercise was developed for each hospital which in turn was based on the highest probable risk. The job action sheets of the HICS were used as measurements of performance. Each indicator was considered as 1, 2 or 3 in accordance with the HICS. Fair performance was determined as hospitals had a hospital disaster management plan. The performance according to HICS was intermediate for 83% (n = 19) of the participating hospitals. No hospital had a high level of performance. The performance level for the individual sections was intermediate or fair, except for the logistic and finance sections which demonstrated a higher level of performance. The public hospitals had overall higher performances than university hospitals (P = 0.04). The decision making performance in the Iranian hospitals, as measured during table top exercises and using the indicators proposed by HICS was intermediate to poor. In addition, this study demonstrates that the HICS job action sheets can be used as a template for measuring the hospital response. Simulations can be used to assess preparedness, but the correlation with outcome remains to be studied.

    Data on hospitalization burden of CAP in children is very limited in China. This study aimed to estimate the hospitalization rate and population-based incidence of hospitalization of CAP for children <15 years of age in Suzhou, China. This was a retrospective study of children hospitalized in Soochow University Affiliated Children's Hospital (SCH) from January 2010 to December 2014. Children who were residents of downtown Suzhou, 29 days to <15 years of age, with discharge diagnosis codes (ICD-10) including J09 to J18 and J20 to J22 were included. All-cause clinical community-acquired pneumonia (CCAP) and radiographically confirmed pneumonia (RCAP) were identified based on individual medical chart review. The hospitalization rate (HR) and population-based cumulative incidence of hospitalization (HI) were calculated. Among 184,734 children <15 years old admitted to SCH during the study period, 31,302 children were identified as having CCAP, and 24,218 (77.4%) children confirmed as having RCAP. CCAP hospitalization occurred year round and peaked during winter and early spring. The overall HRs for CCAP and RCAP were 189.0 (95%CI, 187.1-190.9) and 146.2 (95%CI, 144-148) per 1,000 hospitalizations respectively, and the HIs per 100,000 children annually were CCAP, 3,235.8 (95%CI, 3207.3-3264.2) and RCAP, 2,503.5 (95%CI, 2,478.3-2,528.6). For children <5 years old, the HR for CCAP was 248.4 (95%CI, 245.9-250.9) and RCAP 194.0 (95%CI, 191.4-196.3) per 1,000 hospitalizations; the HI for CCAP was 6,956.2 (95%CI: 6,892.8-7,019.6) and 5,431.9 (95%CI: 5,375.4-5,488.4) per 100,000 children for RCAP. The highest HR and HI were observed in children 29 days to <6 months old: HR for CCAP was 407.4 (95%CI: 400.9-413.9) per 1,000 hospitalizations and HI for CCAP was 11,203.7 (95%CI: 11,026.8-11,380.6) per 100,000 children annually. There is a considerable burden of CAP among children <15 years of age in Suzhou, particularly among children 29 days to <6 months of age and during winter

    To assess the incidence of delirium and its risk factors in hospitalized children with cancer. In this cohort study, all consecutive admissions to a pediatric cancer service over a 3-month period were prospectively screened for delirium twice daily throughout their hospitalization. Demographic and treatment-related data were collected from the medical record after discharge. A total of 319 consecutive admissions, including 186 patients and 2731 hospital days, were included. Delirium was diagnosed in 35 patients, for an incidence of 18.8%. Risk factors independently associated with the development of delirium included age Delirium was associated with increased hospital length of stay, with median length of stay for delirious patients of 10 days compared with 5 days for patients who were not delirious during their hospitalization (P delirium was a frequent complication during admissions for childhood cancer, and was associated with increased hospital length of stay. Multi-institutional prospective studies are warranted to further characterize delirium in this high-risk population and identify modifiable risk factors to improve the care provided to hospitalized children with cancer.

    Full Text Available The purpose of this study was to examine factors that contribute to adverse incidents by creating a model that included patient characteristics, clinical conditions, nursing unit context of care variables, medical treatments, pharmaceutical treatments, and nursing treatments. Data were abstracted from electronic, administrative, and clinical data repositories. The sample included older adults hospitalized during a four-year period at one, academic medical facility in the Midwestern United States who were at risk for falling. Relational databases were built and a multistep, statistical model building analytic process was used. Total registered nurse (RN hours per patient day (HPPD and HPPDs dropping below the nursing unit average were significant explanatory variables for experiencing an adverse incident. The number of medical and pharmaceutical treatments that a patient received during hospitalization as well as many specific nursing treatments (e.g., restraint use, neurological monitoring were also contributors to experiencing an adverse incident.

    In October 2008, the Centers for Medicare & Medicaid Services (CMS) stopped reimbursing hospitals for the marginal cost of treating certain preventable hospital-acquired conditions. This study evaluates whether CMS's refusal to pay for hospital-acquired pulmonary embolism (PE) or deep vein thrombosis (DVT) resulted in a lower incidence of these conditions. We employ difference-in-differences modeling using 2007-2009 data from the Nationwide Inpatient Sample, an all-payer database of inpatient discharges in the U.S. Discharges between 1 January 2007 and 30 September 2008 were considered "before payment reform;" discharges between 1 October 2008 and 31 December 2009 were considered "after payment reform." Hierarchical regression models were fit to account for clustering of observations within hospitals. The "before payment reform" and "after payment reform" incidences of PE or DVT among 65-69-year-old Medicare recipients were compared with three different control groups of: a) 60-64-year-old non-Medicare patients; b) 65-69-year-old non-Medicare patients; and c) 65-69-year-old privately insured patients. Hospital reimbursements for the control groups were not affected by payment reform. CMS payment reform for hospital-based reimbursement of patients with hip and knee replacement surgeries. The outcome was the incidence proportion of hip and knee replacement surgery admissions that developed pulmonary embolism or deep vein thrombosis. At baseline, pulmonary embolism or deep vein thrombosis were present in 0.81% of all hip or knee replacement surgeries for Medicare patients aged 65-69 years old. CMS payment reform resulted in a 35% lower incidence of hospital-acquired pulmonary embolism or deep vein thrombosis in these patients (p = 0.015). Results were robust to sensitivity analyses. CMS's refusal to pay for hospital-acquired conditions resulted in a lower incidence of hospital-acquired pulmonary embolism or deep vein thrombosis after hip or knee replacement surgery

    Full Text Available Systemic dehydration and diffuse central nervous system signs without any other illness is referred to as dehydration encephalopathy (DE. However, the incidence of DE at emergency units remains uncertain. We investigated the incidence of DE among persons with disturbed consciousness who visited the emergency unit. We reviewed the medical case records of the emergency unit at our university hospital during a 6-month period. Among them, 132 patients presented with disturbed consciousness as the sole initial manifestation on arrival. They were 75 men, 47 women; mean age 68 years (16-95 years. After carefully excluding other etiologies, the incidence of DE was 2% among all persons in the emergency unit and 4% among persons older than 68 years.In conclusion, the incidence of DE in our emergency unit was not common. Nevertheless, recognition of DE is extremely important in order to avoid unnecessary medication in elderly subjects.

    Monitoring trends in cardiovascular events can provide key insights into the effectiveness of prevention efforts. Leveraging data from electronic health records provides a unique opportunity to examine contemporary, community-based trends in acute myocardial infarction hospitalizations. We examined trends in hospitalized acute myocardial infarction incidence among adults aged ≥25 years in 13 US health plans in the Cardiovascular Research Network. The first hospitalization per member for acute myocardial infarction overall and for ST-segment elevation myocardial infarction and non-ST-segment elevation myocardial infarction was identified by International Classification of Diseases, Ninth Revision, Clinical Modification primary discharge codes in each calendar year from 2000 through 2008. Age- and sex-adjusted incidence was calculated per 100,000 person-years using direct adjustment with 2000 US census data. Between 2000 and 2008, we identified 125,435 acute myocardial infarction hospitalizations. Age- and sex-adjusted incidence rates (per 100,000 person-years) of acute myocardial infarction decreased an average 3.8%/y from 230.5 in 2000 to 168.6 in 2008. Incidence of ST-segment elevation myocardial infarction decreased 8.7%/y from 104.3 in 2000 to 51.7 in 2008, whereas incidence of non-ST-segment elevation myocardial infarction increased from 126.1 to 129.4 between 2000 and 2004 and then decreased thereafter to 116.8 in 2008. Age- and sex-specific incidence rates generally reflected similar patterns, with relatively larger decreases in ST-segment elevation myocardial infarction rates in women compared with men. As compared with 2000, the age-adjusted incidence of ST-segment elevation myocardial infarction in 2008 was 48% lower among men and 61% lower among women. Among a large, diverse, multicenter community-based insured population, there were significant decreases in incidence of hospitalized acute myocardial infarction and the more serious ST-segment elevation

    Case series and case-control studies have shown high rates of psychosocial and behavioural risk factors amongst patients admitted to hospital with severe asthma. General population studies have shown associations between psychosocial factors and prevalent asthma but few have investigated incident asthma outcomes. Data on psychosocial factors and asthma hospital admissions were available for 20 854 participants, aged 41-80 years, in the Norfolk cohort of the European Prospective Investigation into Cancer study. Postal assessments included details of physical functioning, mood disorder history, social adversity and social support. A total of 686 asthma hospital admissions were recorded. Psychosocial factors present at baseline, including current mood disorders, adverse circumstances in childhood, the impact of life events experienced during adulthood and negative perceived support from a close confidant, were associated with increased rates of hospital admission independent of age, sex, indicators of socio-economic status, physical functional health, and obesity. Restricted to those participants who reported lifetime doctor-diagnosed asthma at baseline, the reported impact of adverse life events experienced in adulthood, and both confiding and negative aspects of support quality, were associated with asthma hospital admission. The magnitude of these associations was comparable to those involving indicators of socio-economic status and physical health. These results show that psychosocial factors are associated with incident asthma hospital admissions and highlight the potential importance of taking account of psychosocial factors, including availability and quality of support networks, in guiding long-term asthma management.

    Immunochromatographic urine pneumococcal antigen testing (ICT) has become a common diagnostic tool for those presenting with possible invasive pneumococcal disease. The incidence and clinical impact of ICT false-positivity on hospitalized patients has not been assessed outside of specific patient subpopulations. ICT performance needs to be assessed in a real-world clinical setting. This study aims to describe the incidence and clinical impact of ICT false-positivity in a hospital setting over a 19-month period. A retrospective cohort study was performed to assess the incidence of false-positive (FP) ICT among hospitalized patients from November 21, 2007 to June 30, 2009. The primary objective was to describe the incidence of FP ICT results. The secondary objective was to describe what clinical impact, if any, could be attributed to FP ICT results. During the study period, 52 positive ICT results were obtained, of which 5 (9.6%) were deemed falsely positive. Interestingly, two of the 5 FP results were from patients who had received 23-valent pneumococcal vaccine (PPV) in the 2 days prior to ICT. The management of all 5 patients was impacted by the FP results through unnecessary antimicrobial treatment and/or deferral of further clinical evaluation. Health care providers should be aware of the potential for ICT FP and should order and interpret these tests within an informed clinical framework.

    Nowadays, application of nuclear technology in different industries has largely expanded worldwide. Proportionately, the risk of nuclear incidents and the resulting injuries have, therefore, increased in recent years. Preparedness is an important part of the crisis management cycle; therefore efficient preplanning seems crucial to any crisis management plan. Equipped with facilities and experienced personnel, hospitals naturally engage with the response to disasters. The main purpose of our study was to present a practical management pattern for hospitals and medical centers in case they encounter a nuclear emergency. In this descriptive qualitative study, data were collected through experimental observations, sources like Safety manuals released by the International Atomic Energy Agency and interviews with experts to gather their ideas along with Delphi method for polling, and brainstorming. In addition, the 45 experts were interviewed on three targeted using brainstorming and Delphi method. We finally proposed a management plan along with a set of practicality standards for hospitals and medical centers to optimally respond to nuclear medical emergencies when a radiation incident happens nearby. With respect to the great importance of preparedness against nuclear incidents adoption and regular practice of nuclear crisis management codes for hospitals and medical centers seems quite necessary.

    To determine whether specific subsets of symptoms from the Geriatric Depression Scale (GDS), assessed at hospital admission, were associated with the incidence of delirium. Secondary analysis of a prospective cohort study of patients from the Delirium Prevention Trial. General medicine service at Yale New Haven Hospital, March 25, 1995, through March 18, 1998. Four hundred sixteen patients aged 70 and older who were at intermediate or high risk for delirium and were not taking antidepressants at hospital admission. Depressive symptoms were assessed GDS, and daily assessments of delirium were obtained using the Confusion Assessment Method. Of the 416 patients in the analysis sample, 36 (8.6%) developed delirium within the first 5 days of hospitalization. Patients who developed delirium reported 5.7 depressive symptoms on average, whereas patients without delirium reported an average of 4.2 symptoms. Using a Cox proportional hazards model, it was found that depressive symptoms assessing dysphoric mood and hopelessness were predictive of incident delirium, controlling for measures of physical and mental health. In contrast, symptoms of withdrawal, apathy, and vigor were not significantly associated with delirium. These findings suggest that assessing symptoms of dysphoric mood and hopelessness could help identify patients at risk for incident delirium. Future studies should evaluate whether nonpharmacological treatment for these symptoms reduces the risk of delirium.

    Hospital incident reporting systems are usually evaluated on their theoretical benefit to the hospital or increase in reporting rates alone. To evaluate a workflow-based response system on staff incident reporting rates. A prospective cohort study of incident reports made by staff members before (2006-2007) and after (2008-2009) the system was implemented on 1 January 2008 at a medical center in southern Taiwan. Pre-system and post-system data were based on 713 129 and 730 176 inpatient days and 160 692 and 168 850 emergency department visits. The addition of a workflow-based response system to a reporting system processing incident reports and intra-hospital responses. Voluntary incident reporting rates and distribution of incident severities. Inpatient reports [9.9 vs. 28.8 per 10 000 patient days; rate ratio (RR): 2.9, 95% confidence interval (CI): 2.7-3.2, P reports (5.9 vs. 19.2 per 10 000 visits, RR: 3.3, 95% CI: 2.6-4.1, P system reported incidents were more evenly distributed over five severity levels than pre-sytem incidents, moving more toward the very severe level (RR: 17.6, 95% CI: 8.4-37.0, P system to the hospital incident reporting system significantly increased hospital-wide voluntary incident report rates at all incident injury levels.

    This study aimed to empirically compare incident reporting systems (IRS) in two European countries and to explore the relationship of IRS characteristics with context factors such as hospital characteristics and characteristics of clinical risk management (CRM). We performed exploratory, secondary analyses of data on characteristics of IRS from nationwide surveys of CRM practices. The survey was originally sent to 2136 hospitals in Germany and Switzerland. Persons responsible for CRM in 622 hospitals completed the survey (response rate 29%). None. Differences between IRS in German and Swiss hospitals were assessed using Chi2, Fisher's Exact and Freeman-Halton-Tests, as appropriate. To explore interrelations between IRS characteristics and context factors (i.e. hospital and CRM characteristics) we computed Cramer's V. Comparing participating hospitals across countries, Swiss hospitals had implemented IRS earlier, more frequently and more often provided introductory IRS training systematically. German hospitals had more frequently systematically implemented standardized procedures for event analyses. IRS characteristics were significantly associated with hospital characteristics such as hospital type as well as with CRM characteristics such as existence of strategic CRM objectives and of a dedicated position for central CRM coordination. This study contributes to an improved understanding of differences in the way IRS are set up in two European countries and explores related context factors. This opens up new possibilities for empirically informed, strategic interventions to further improve dissemination of IRS and thus support hospitals in their efforts to move patient safety forward. © The Author 2017.

    The aims of this study were to examine sexual harassment (SH) among hospital staffs in Taiwan, in terms of three-month incidence rate, the frequency of each type and the perception of SH, perpetrated by coworkers, patients and patients' families and to investigate the gender differences for these issues. The subjects were employees at two general hospitals in Taiwan. The self-administered "Hospital Sexual Harassment Questionnaire" was sent to eligible staff, and the voluntary respondents answered the questionnaire anonymously. There were 536 respondents available for analysis, with an overall response rate of 43.4%. The three-month incidence rates of SH by coworkers, patients, and patients' families in our study population were 2.4, 4.3, and 1.7%, respectively. Telling sexual jokes was the most common type of SH. The males had greater opportunities to be exposed to porn videos by their coworkers. The females were more frequently exposed to sex jokes and remarks made by patients and their family members and unwanted physical touching by patients in the workplace. There were significant differences with regard to the perception of sex jokes and sexually explicit verbal descriptions as SH or not between genders. The information in this study can be a helpful reference for administrators in hospitals when they are establishing education plans and policies. It might be possible to prevent sexual harassment and misunderstandings between genders and to further avoid the negative impact on the emotional well-being of workers in hospitals.

    Full Text Available Introduction: Postoperative pain remains as a problem. National studies report incidences of 31% for moderate and 22% for severe pain. Inadequate analgesia is related to dissatisfaction and adverse outcomes. The aim of this study was to describe the incidence and characteristics of the postoperative pain in the post-anesthesia care unit (PACU at Hospital Universitario San José of Popayán (HUSJ in patients undergoing general anesthesia during the first postoperative hour. Methods: Cohort study. We recruited patients attending PACU and undergoing procedures using general anesthesia, between 18 and 70 years. Using a standardized collection form medical history, demographic data, medical history, anesthetic management, intraoperative analgesia and postoperative pain assessment by verbal and numerical pain scale (1-10 were recorded. Postoperative outcome data were also collected in the PACU. Results: The incidence of severe postoperative pain at 10 minutes was 12.3% 95%CI [7.1-18.2] (19 patients. Within 30 minutes of assessment 4.5% 95%CI [1.3-8.4] (7 patients and 1.9% 60 minutes 95%CI [0-4.5] (3 patients. 48.7% required rescue analgesic at PACU. Incidence of postoperative nausea and vomiting (PONV was significantly different in patients requiring rescue analgesic. Conclusion: The incidence of severe postoperative pain in the first postoperative hour at HUSJ is close to 12% and it decreases as time goes by. Patients requiring rescue analgesic have a higher incidence of postoperative complications such as PONV.

    Medication errors cause a large number of adverse drug events with negative patient health outcomes and are a major public-health burden contributing to 18.7-56 % of all adverse drug events among hospitalized patients. The aim of this study was to assess the incidence and determinants of medication errors and adverse drug events among hospitalized children. A prospective observational study was conducted among hospitalized children in the pediatrics ward of Nekemte Referral Hospital from February 24 to March 28, 2014. Data were collected by using checklist guided observation and review of medication order sheets, medication administration records, and other medical charts of the patients. To identify the independent predictors of medication errors and adverse drug events, backward logistic regression analysis was used. Statistical significance was considered at p-value Nekemte Referral Hospital. In particular, children with multiple medications and longer hospital stays, and those with co-morbidities and longer hospital stays, were at greater risk for medication errors and adverse drug events, respectively.

    Full Text Available INTRODUCTION: Automated dose dispensing (ADD is being introduced in several countries and the use of this technology is expected to increase as a growing number of elderly people need to manage their medication at home. ADD aims to improve medication safety and treatment adherence, but it may introduce new safety issues. This descriptive study provides insight into the nature and consequences of medication incidents related to ADD, as reported by healthcare professionals in community pharmacies and hospitals. METHODS: The medication incidents that were submitted to the Dutch Central Medication incidents Registration (CMR reporting system were selected and characterized independently by two researchers. MAIN OUTCOME MEASURES: Person discovering the incident, phase of the medication process in which the incident occurred, immediate cause of the incident, nature of incident from the healthcare provider's perspective, nature of incident from the patient's perspective, and consequent harm to the patient caused by the incident. RESULTS: From January 2012 to February 2013 the CMR received 15,113 incidents: 3,685 (24.4% incidents from community pharmacies and 11,428 (75.6% incidents from hospitals. Eventually 1 of 50 reported incidents (268/15,113 = 1.8% were related to ADD; in community pharmacies more incidents (227/3,685 = 6.2% were related to ADD than in hospitals (41/11,428 = 0.4%. The immediate cause of an incident was often a change in the patient's medicine regimen or relocation. Most reported incidents occurred in two phases: entering the prescription into the pharmacy information system and filling the ADD bag. CONCLUSION: A proportion of incidents was related to ADD and is reported regularly, especially by community pharmacies. In two phases, entering the prescription into the pharmacy information system and filling the ADD bag, most incidents occurred. A change in the patient's medicine regimen or relocation was the immediate causes of an

    Nosocomial infections pose substantial risk to patients receiving care in hospitals. In Africa, this problem is aggravated by inadequate infection control due to poor hygiene, resource and structural constraints, deficient surveillance data and lack of awareness regarding nosocomial infections. We carried out this study to determine the incidence and spectrum of nosocomial infections, pathogens and antibiotic resistance patterns in a tertiary regional hospital in Lambaréné, Gabon. This prospective case study was carried out over a period of six months at the Albert Schweitzer Hospital, Lambaréné, Gabon. All patients admitted to the departments of surgery, gynecology/obstetrics and internal medicine were screened daily for signs and symptoms of hospital-acquired infections. A total of 2925 patients were screened out of which 46 nosocomial infections (1.6%) were diagnosed. These comprised 20 (44%) surgical-site infections, 12 (26%) urinary-tract infections, 9 (20%) bacteraemias and 5 (11%) other infections. High rates of nosocomial infections were found after hysterectomies (12%) and Caesarean sections (6%). Most frequent pathogens were Staphylococcus aureus and Escherichia coli. Eight (40%) of 20 identified E. coli and Klebsiella spp. strains were ESBL-producing organisms. The cumulative incidence of nosocomial infections in this study was low; however, the high rates of surgical site infections and multi-resistant pathogens necessitate urgent comprehensive interventions of infection control.

    Full Text Available Hospital Incident Command System (HICS has been established with the mission of prevention, response, and recovery in hazards. Regarding the key role of hospitals in medical management of events, the present study is aimed at investigating benefits, barriers, and limitations of applying HICS in hospital. Employing a review study, articles related to the aforementioned subject published from 1995 to 2016 were extracted from accredited websites and databases such as PubMed, Google Scholar, Elsevier, and SID by searching keywords such as HICS, benefits, barriers, and limitations. Then, those articles were summarized and reported. Using of HICS can cause creating preparedness in facing disasters, constructive management in strategies of controlling events, and disasters. Therefore, experiences indicate that there are some limitations in the system such as failure to assess the strength and severity of vulnerabilities of hospital, no observation of standards for disaster management in the design, constructing and equipping hospitals, and the absence of a model for evaluating the system. Accordingly, the conducted studies were investigated for probing the performance HICS. With regard to the role of health in disaster management, it requires advanced international methods in facing disasters. Using accurate models for assessing, the investigation of preparedness of hospitals in precrisis conditions based on components such as command, communications, security, safety, development of action plans, changes in staff's attitudes through effective operational training and exercises and creation of required maneuvers seems necessary.

    Estimating the incidence rate of pressure ulcers and verifying factors associated with this occurrence in a cohort of hospitalized patients. This is a cohort study in which the considered outcome was the time until pressure ulcer occurrence. Estimated effect of the variables on the cumulative incidence ratio of the outcome was performed using the Cox proportional hazards model. Variable selection occurred via the Logrank hypothesis test. The sample consisted of 442 adults, with 25 incidents of pressure ulcers. Patients with high scores on the Braden scale presented a higher risk of pressure ulcer incidence when compared to those classified into the low score category. These results reinforce the importance of using the Braden Scale to assist in identifying patients more likely to develop pressure ulcers.

    Objectives: To determine the incidence and pattern of various congenital heart disease in a neonatal unit of a tertiary care hospital. Methods: The prospective study was carried out in the neonatal unit of Combined Military Hospital, Rawalpindi, from September 2008 to August 2011. All 5800 neonates admitted with gestational age of >28 weeks irrespective of birthweight were included in the study. Neonatologist/Paediatrician carried out the neonatal examination during the first 12 hours of life. Neonates suspected of having congenital heart disease were further evaluated by pulse oxymetry, X-ray chest and echocardiography to ascertain final diagnosis and type of lesion. Data was collected on a predesigned proforma containing information regarding gender, mode of delivery, gestational age, weight at birth, family history, and associated malformations. SPSS 16 was used for statistical analysis. Results: Of the 5800 neonates, 87 (1.5%) were found to have congenital heart disease with an incidence of 15/1000. There was a male preponderance. Most common lesion was ventricular septal defect 27(31.3%), followed by atrial septal defect 20 (22.9%), patent ductus arteriosus 13 (14.94%), tetralogy of fallot 06 (6.89%), transposition of great arteries 04 (4.59%), Pulmonary stenosis 05 (5.79%) and 03(3.44%) had atrioventricular canal defects. Conclusion: Congenital heart disease is a common congenital anomaly. Its incidence varies from centre to centre due to different factors like nature of the sample, method of detection and early examination by a neonatologist/paediatrician. In this study a higher incidence is reported because it was carried out in a tertiary care unit, which is a referral hospital and all the neonates admitted in the unit were included in the study.

    Full Text Available Abstract Background A significant proportion of surgical patients are unintentionally harmed during their hospital stay. Root Cause Analysis (RCA aims to determine the aetiology of adverse incidents that lead to patient harm and produce a series of recommendations, which would minimise the risk of recurrence of similar events, if appropriately applied to clinical practice. A review of the quality of the adverse incident reporting system and the RCA of serious adverse incidents at the Department of Surgery of Ninewells hospital, in Dundee, United Kingdom was performed. Methods The Adverse Incident Management (AIM database of the Department of Surgery of Ninewells Hospital was retrospectively reviewed. Details of all serious (red, sentinel incidents recorded between May 2004 and December 2009, including the RCA reports and outcomes, where applicable, were reviewed. Additional related information was gathered by interviewing the involved members of staff. Results The total number of reported surgical incidents was 3142, of which 81 (2.58% cases had been reported as red or sentinel. 19 of the 81 incidents (23.4% had been inappropriately reported as red. In 31 reports (38.2% vital information with regards to the details of the adverse incidents had not been recorded. In 12 cases (14.8% the description of incidents was of poor quality. RCA was performed for 47 cases (58% and only 12 cases (15% received recommendations aiming to improve clinical practice. Conclusion The results of our study demonstrate the need for improvement in the quality of incident reporting. There are enormous benefits to be gained by this time and resource consuming process, however appropriate staff training on the use of this system is a pre-requisite. Furthermore, sufficient support and resources are required for the implementation of RCA recommendations in clinical practice.

    Carbapenemase-producing Enterobacteriaceae are increasingly reported worldwide. The aim of the study was to determine the incidence and molecular epidemiology of carbapenemase-producing (CP) Escherichia coli and Klebsiella pneumoniae (CP-E/K) in Belgium. Eleven hospital-based laboratories collected carbapenem non-susceptible (CNS) isolates of E. coli and K. pneumoniae detected in clinical specimens from January 2013 to December 2014. All CNS strains were tested for carbapenemase production and typed by multilocus sequence typing (MLST) for a 6-month period as part of the European Survey on Carbapenemase-Producing Enterobacteriaceae in Europe (EuSCAPE) structured survey. In addition, an equal number of carbapenem-susceptible isolates collected were preserved as a control group for risk factor analysis. The overall incidence rate of CP-E/K isolates in hospitals increased from 0.124 in 2013 to 0.223 per 1000 admissions in 2014. From November 2013 to April 2014, 30 CP K. pneumoniae [OXA-48 (n = 16), KPC (n = 13), OXA-427 (n = 1)] and five CP E. coli [OXA-48 (n = 3), NDM (n = 1), OXA-427 (n = 1)] isolates were detected in ten hospitals. The 16 OXA-48-producing K. pneumoniae strains were distributed into eight sequence types (STs), while the 13 KPC-producing K. pneumoniae clustered into three STs dominated by ST512 (n = 7) and ST101 (n = 5). Compared to controls, we observed among CP-E/K carriers significantly higher proportion of males, respiratory origins, previous hospitalization, nosocomial setting, and a significantly lower proportion of bloodstream infections. Our study confirms the rapid spread of CP-E/K in Belgian hospitals and the urgent need for a well-structured and coordinated national surveillance plan in order to limit their dissemination.

    The study was aimed at assessing the cumulative incidence of hypoglycemia and precipitating risk factors among type 2 diabetes mellitus in-patients of a tertiary care hospital in South India. The prospective cross sectional study spanning 14 months was conducted in a tertiary care hospital in Kerala. All T2DM patients who were administered any form of insulin during the length of hospital stay was monitored for assessing the hypoglycemic episodes. Any patient with a GRBS value less than 70mg/dL was defined to be hypoglycemic as per the ADA guidelines. The statistical analysis of collected data was performed using SPSS 18 for windows version. Of the 1650 subjects enrolled in the study, 204 subjects developed hypoglycemia. The sample composed of 60.8% females and 39.2% males and the difference was significant with p=0.02. A significant positive correlation was observed between HbA1c values and GRBS value, with a 2 tailed Pearson correlation coefficient of 0.027. On stratifying as per the modality of insulin dose prescribed, 72.5% of the hypoglycemic patients were found to have been administered fixed dose insulin. The cumulative incidence of institutional hypoglycemia among type 2 diabetic inpatients was gauged as 12.36%; among which, 26.96% had asymptomatic episodes. Copyright © 2016 Diabetes India.

    To identify factors contributing to the development of anaesthetic safety incidents. Prospective, descriptive, voluntary reporting audit of safety incidents with subsequent systems analysis. All animals anaesthetized in a multispecies veterinary teaching hospital from November 2014 to October 2016. Peri-anaesthetic incidents that risked or caused unnecessary harm to an animal were reported by anaesthetists alongside animal morbidity and mortality data. A modified systems analysis framework was used to identify contributing factors from the following categories: Animal and Owner, Task and Technology, Individual, Team, Work Environmental, and Organizational and Management. The outcome was graded using a simple descriptive scale. Data were analysed using Pearson's Chi-Square test for association and univariable and multivariable logistic regression analysis. Totally, 3379 anaesthetics were performed during the audit period. Of these, 174 incident reports were analysed, 163 of which impacted safe veterinary care and 26 incidents were considered to have had major or catastrophic outcomes. Incident outcome was believed to have been limited by anaesthetist intervention in 104 (63.8%) cases. Various factors were identified as: Individual in 123 (70.7%), Team in 108 (62.1%), Organizational and Management in 94 (54.0%), Task and Technology in 80 (46.0%), Work Environmental in 53 (30.5%) and Animal and Owner in 36 (20.7%) incidents. Individual factors were rarely seen in isolation. Significant associations were identified between Experience and Supervision, X 2 (1, n=174)=54177, p=0.001, Failure to follow a standard operating procedure and Task Management, X 2 (2, n=174)=11318, p=0.001, and Staffing and Poor Scheduling, X 2 (1, n=174)=36742, p=0.001.

    To evaluate the performance of a routine incident reporting system in identifying patient safety incidents. Two stage retrospective review of patients' case notes and analysis of data submitted to the routine incident reporting system on the same patients. A large NHS hospital in England. 1006 hospital admissions between January and May 2004: surgery (n=311), general medicine (n=251), elderly care (n=184), orthopaedics (n=131), urology (n=61), and three other specialties (n=68). Proportion of admissions with at least one patient safety incident; proportion and type of patient safety incidents missed by routine incident reporting and case note review methods. 324 patient safety incidents were identified in 230/1006 admissions (22.9%; 95% confidence interval 20.3% to 25.5%). 270 (83%) patient safety incidents were identified by case note review only, 21 (7%) by the routine reporting system only, and 33 (10%) by both methods. 110 admissions (10.9%; 9.0% to 12.8%) had at least one patient safety incident resulting in patient harm, all of which were detected by the case note review and six (5%) by the reporting system. The routine incident reporting system may be poor at identifying patient safety incidents, particularly those resulting in harm. Structured case note review may have a useful role in surveillance of routine incident reporting and associated quality improvement programmes.

    We present a retrospective study depicting the incidence and outcome of soft tissue sarcomas (STSs) in patients admitted in a District Government Hospital situated in coastal belt of Southern India for a period of four and a half years. The hospital is a district referral centre catering to rural and urban poor population of 1,900,000 people. Histologically proven soft tissue STS patients admitted in Department of General Surgery in District Government Wenlock Hospital, Mangalore, from January 2002 to July 2007 were included in the study. The incidence, age distribution, gender distribution, histological subtypes, site of tumour, and clinical outcome were the parameters studied. The above parameters were then compared with Memorial Sloan and Kettering Cancer Centre (MSKCC) study. Fifty-one cases of STS were reported out of 7674 (0.65%) patients with cancer in the said period. Ninety percent belonged to adolescents and adult age group. Liposarcoma (18%) is the most common subtype followed by leiomyosarcoma, Ewings' sarcoma. 66.6% originated in the extremities and rest being intra-abdominal and retroperitoneal. The age of presentation was a decade less than MSKCC study. The alarming yet expected fact was 35% of patients came with delayed presentation of the disease and refusal for surgery. Thirty-nine percent of patients were treated surgically. Majority of patients presenting to our institution in advanced stage of the disease, indicating ignorance, fear and reluctance for surgery; as well as economic constraints, that delay early detection and initiation of proper treatment. The incidence appears to be increasing, targeting the younger population. There is a definite need to incorporate drug trials in rural set up so that patients can be benefited.

    Cutaneous adverse drug reactions (cADRs) are common. There are only few studies on the incidence of cADRs in Malaysia. To determine the incidence, clinical features and risk factors of cADRs among hospitalized patients. A prospective study was conducted among medical inpatients from July to December 2014. A total of 43 cADRs were seen among 11 017 inpatients, yielding an incidence rate of 0.4%. cADR accounted for hospitalization in 26 patients. Previous history of cADR was present in 14 patients, with 50% exposed to the same drug taken previously. Potentially lifethreatening severe cutaneous adverse reactions (SCAR), namely drug reaction with eosinophilia and systemic symptoms (DRESS: 14 cases) and Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis (SJS/TEN: 6 cases) comprise almost 50% of cADRs. The commonest culprit drug group was antibiotics (37.2%), followed by anticonvulsants (18.6%). Cotrimoxazole, phenytoin and rifampicin were the main causative drugs for DRESS. Anticonvulsants were most frequently implicated in SJS/TEN (66.7%). Most cases had "probable" causality relationship with suspected drug (69.8%). The majority of cases were of moderate severity (65.1%), while 18.6% had severe reaction with 1 death recorded. Most cases were not preventable (76.7%). Older age (> 60 years) and mucosal involvement were significantly associated with a more severe reaction. The incidence of cADRs was 0.4%, with most cases classified as moderate severity and not preventable. The commonest reaction pattern was DRESS, while the main culprit drug group was antibiotics. Older age and mucosal membrane involvement predicts a severe drug reaction.

    To identify factors affecting nurse-perceived sexual harassment and specific types of patient sexual behavior experienced by Japanese nurses. Cross-sectional questionnaire study of Japanese hospital nurses. Self-administered questionnaires (N=600) were distributed to Japanese hospital nurses, and 464 were returned (response rate of 77.3%). Two instruments were used: one was for determining sexual harassment by patients, and the other was for determining specific types of patient behavior that had sexual connotations. Registered nurses were at a much higher risk of sexual harassment than were nurse assistants. In addition, registered nurses had a much more positive attitude toward gender equality compared with assistant nurses. A positive attitude toward gender equality mediated by a relatively high education level might be associated with increasing reports of sexual harassment. An increasing incidence of sexual harassment claims among nurses should prompt hospital organizations to take proper action against it. Education on gender equality was thus considered a long-term solution for reducing the sexual harassment of Japanese hospital nurses. Establishing a safer working environment could enable nurses to provide better care for patients and thereby promote the development of good relationships between nurses and patients.

    Studies have reported increasing incidence of ischemic stroke in adults younger than 50 to 55 years. Information on temporal trends of other stroke subtypes and transient ischemic attack (TIA) is sparse. The aim of this study was to investigate temporal trends of the incidence of hospitalizations for TIA and stroke including sex- and subtype-specific trends in young adults aged 15 to 30 years. From the Danish National Patient Register, we identified all cases of first-ever stroke and TIA (age 15-30 years) in Denmark, who were hospitalized during the study period of 1994 to 2012. Incidence rates and estimated annual percentage changes (EAPCs) were estimated by using Poisson regression. During the study period, 4156 cases of first-ever hospitalization for stroke/TIA were identified. The age-standardized incidence rates of hospitalizations for stroke increased significantly (EAPC 1.83% [95% CI 1.11-2.55%]) from 11.97/100 000 person-years (PY) in 1994 to 16.77/100 000 PY in 2012. TIA hospitalizations increased from 1.93/100 000 PY in 1994 to 5.81/100 000 PY in 2012 and after 2006 more markedly in men than in women (EAPC 16.61% [95% CI 10.45-23.12%]). The incidence of hospitalizations for ischemic stroke was markedly lower among men, but increased significantly from 2006 (EAPC 14.60% [95% CI 6.22-23.63%]). The incidences of hospitalizations for intracerebral hemorrhage and subarachnoid hemorrhage remained stable during the study period. The incidence rates of first-time hospitalizations for ischemic stroke and TIA in young Danish adults have increased substantially since the mid 1990s. The increase was particularly prominent in the most recent years. © 2016 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley Blackwell.

    Full Text Available Newborn screening for the detection of inborn errors of metabolism (IEM, endocrinopathies, hemoglobinopathies, and other disorders is a public health initiative aimed at identifying specific diseases in a timely manner. Mexico initiated newborn screening in 1973, but the national incidence of this group of diseases is unknown or uncertain due to the lack of large sample sizes of expanded newborn screening (ENS programs and lack of related publications. The incidence of a specific group of IEM, endocrinopathies, hemoglobinopathies, and other disorders in newborns was obtained from a Mexican hospital. These newborns were part of a comprehensive ENS program at Ginequito (a private hospital in Mexico, from January 2012 to August 2014. The retrospective study included the examination of 10 000 newborns’ results obtained from the ENS program (comprising the possible detection of more than 50 screened disorders. The findings were the following: 34 newborns were confirmed with an IEM, endocrinopathies, hemoglobinopathies, or other disorders and 68 were identified as carriers. Consequently, the estimated global incidence for those disorders was 3.4 in 1000 newborns; and the carrier prevalence was 6.8 in 1000. Moreover, a 0.04% false-positive rate was unveiled as soon as diagnostic testing revealed negative results. The most frequent diagnosis was glucose-6-phosphate dehydrogenase deficiency; and in the case of carriers, it was hemoglobinopathies. The benefit of the ENS is clear as it offers prompt treatment on the basis of an early diagnosis including proper genetic counseling. Furthermore, these results provide a good estimation of the frequencies of different forms of newborn IEM, endocrinopathies, hemoglobinopathies, and other disorders at Ginequito.

    Twin pregnancy is associated with more pregnancy complications and poorer pregnancy outcome than singleton pregnancy. Hence periodic review is necessary to improve on the pregnancy outcome. To determine the incidence and compare pregnancy complications and obstetric outcomes of twin pregnancies and singleton pregnancies. The twin pregnancies (study group) that were delivered at Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, South-East Nigeria from 1st February 2005 to 31st January 2010 were compared with singleton deliveries (control group) that occurred in the same hospital during the same period. A total of 3351 deliveries were conducted during the study period, of which 113 were twin deliveries, giving an incidence of 1:29.6 deliveries. Only 100 case files could be retrieved for analysis. The mean parities for the twins and singletons were 2.7 ± 2.33 weeks and 1.96 ± 1.87 weeks whereas the mean gestational age at delivery for twin and singleton deliveries were 34 ± 5.2 weeks and 38.7 ± 2.4 weeks respectively (P < 0.05). The mean birth weights were 3.14 ± 0.73 kg and 2.3 ± 1.0 kg for singletons and twins respectively (P < 0.05). Hypertensive disorders of pregnancy, cord prolapse, malpresentation, premature rupture of membranes, low Apgar scores, cesarean section rate, and perinatal death were significantly higher in twin pregnancies than in singleton. The incidence of twin pregnancy over the study period was high and was significantly associated with more pregnancy complications and poorer obstetric outcomes. Close antenatal and intrapartum care are needed in order to improve outcome and decrease complications.

    Full Text Available Abstract Background Cirrhotic patients are characterized by a decreased synthesis of coagulation and anticoagulation factors. The coagulopathy of cirrhotic patients is considered to be auto-anticoagulation. Our aim was to determine the incidence and predictors of venous thromboembolism (VTE and examine the practice of deep venous thrombosis (DVT prophylaxis among hospitalized cirrhotic patients. Methods A retrospective cohort study was performed in a tertiary teaching hospital. We included all adult patients admitted to the hospital with a diagnosis of liver cirrhosis from January 1, 2009 to December 31, 2009. We grouped our cohort patients in two groups, cirrhotic patients without VTE and cirrhotic with VTE. Results Over one year, we included 226 cirrhotic patients, and the characteristics of both groups were similar regarding their clinical and laboratory parameters and their outcomes. Six patients (2.7% developed VTE, and all of the VTEs were DVT. Hepatitis C was the most common (51% underlying cause of liver cirrhosis, followed by hepatitis B (22%; 76% of the cirrhotic patients received neither pharmacological nor mechanical DVT prophylaxis. Conclusion Cirrhotic patients are at risk for developing VTE. The utilization of DVT prophylaxis was suboptimal.

    A survey was carried out in Khartoum North Ahmed Gasim specialist Hospital for children to identify aetiological factors that lead to incidence of nutritional anaemia among children under under five years of age. The sample consists of 192 patients taken from the hospital wards (experimental group), and 60 healthy children taken from out patient vaccination department of same hospital. A questionnaire was used as a tool for collection data regarding children and their families with emphasis to general information, socio-economic information, dietary information, anthropometric information, medical history and laboratory investigations including haemoglobin, hematocrit (PCV)%, peripheral blood picture, serum ferritin, serum folate and serum B 12 . Results show no correlation between anaemia and age R(0.1048) p 1 2 deficiency. Some children affected had mixed deficiency anaemia (3.182). Iron deficiency without anaemia was common among healthy children (control) 22.8%. Some recommendations were set for the improvement of the existing situation e.g. health education, nutrition education with emphasis on intake of supplements and weaning diets rich in iron and folate. Follow up and surveillance program to compact nutritional anaemia should be adopted.(Author)

Pneumonia was frequent in first-time exacerbations (36.1%, but declined in successive exacerbations to 25.6% by the seventh or greater exacerbation. Pneumonic COPD exacerbations increased 20% from 0.92 per 1,000 population in 2006 to 1.10 per 1,000 population in 2012. Nonpneumonic exacerbations decreased by 6% from 1.74 per 1,000 population to 1.63 per 1,000 population during the same period. A number of markers of health resource utilization were more prevalent in pneumonic exacerbations than in nonpneumonic exacerbations: length of stay (median 7 vs 4 days, intensive care unit admission (7.7% vs 12.5%, and several acute procedures. Thirty-day mortality was 12.1% in first-time pneumonic COPD exacerbations versus 8.3% in first-time nonpneumonic cases (adjusted HR [aHR] 1.20, 95% confidence interval [CI] 1.17–1.24. Pneumonia also predicted increased mortality associated with a second exacerbation (aHR 1.14, 95% CI 1.11–1.18, and up to a seventh or greater exacerbation (aHR 1.10, 95% CI 1.07–1.13. In contrast, the aHR of a subsequent exacerbation was 8%–13% lower for patients with pneumonic exacerbations.Conclusions: Pneumonia is frequent among patients hospitalized for COPD exacerbations and is associated with increased health care

    Full Text Available Background: Mongolian spots are the most frequently encountered pigmented lesions in newborns. The patches appear at birth or shortly there after, rarely later the MS in term newborns in always present at birth. The shape of MS was commonly either irregular or indefinite, with its borders gradually blending with the surrounding skin. The color most frequently observed in all ethnic groups was blue- green. For the Negro population the color was commonly greenish- blue the next most common color in the total population was blue- gray. Brown coloration in the form of brown specks on a back ground of blue was present in ten percent Negro Newborns. The most common location is the sacra- gluteal region, which frequently is the only part affected. MS occasionally are found in the extremities in those cases with extensive involvement, particularly in the shoulders. The presence of MS in the head or neck has been called aberrant Mongolian spot. The macula has been variously described as irregularly round, oval, roughly triangular, heart shaped, resembling a tennis racket, and angular. The size may vary from a dot of a few millimeters to six or more centimeters in diameter the mark of ten disappears during the first or second year of life. Those marks distant from the sacral region are said to be more apt to persist than the typical sacral one and the buttocks was the site of predilection. Its incidence varies from over 80% in Asians (Mongolian and Chinese to 10% of white infants. Only a limited number of studies were carried out in Iran. Our objective was to study Mongolian spots incidence and common locations in newborns at Shariati hospital."nMethods: During 2004-06, 2305 consecutive newborns were examined at Shariati hospital. Diagnosis of Mongolian spot was based on clinical impression with Pediatricians."nResults: Mongolian spot was observed in 11.4% neonates. The most frequent site of involvement is the sacral, followed by the gluteal area

    Full Text Available Background: Hypothermia is very prevalent in neonatal transport and can increase morbidity and mortality in this age group. Materials and Methods: In this study, all neonates transported from different parts of Bushehr province to Ali Asghar hospital during the second half (2007 were checked for axillary temperature on admission. Results: 328 neonates were entered to the study. The incidence of hypothermia was 47.6 percent. There was a significant relationship between hypothermia and transfer method (with or without incubator, gestational age, chronological age on admission, birth weight, Apgar score (P<0.0001 and neonatal outcome (P=0.001. Conclusion: Hypothermia leads to increased mortality in neonates and is related to prematurity and low birth weight and low Apgar score. Kangaroo mother care (KMC is recommended instead of incubator care to prevent hypothermia during transfer.

    Bloodstream infection related to a central venous catheter in the intensive care unit is a substantial clinical and economic problem. The aim of the study was to examine the incidence of central line related bloodstream infections and central line associated bloodstream infections in Our Lady of Lourdes Hospital, Drogheda, during a six month period, using an active patient based prospective surveillance method. CLRBSI rate in ICU/HDU was 0.93/1000 central line days. There was no CLABSI identified in the studied time period. However, further interventions are needed, particularly with CVC care bundle. Also, the implementation of 2% chlorhexidin in 70% isopropylalcohol use for skin asepsis, which is recommended by the Irish national guidelines, would be beneficial.

    Smoking is a well-established risk factor for cardiovascular disease (CVD) and acute myocardial infarction (AMI). Exposure to tobacco smoke is associated with an estimated 35,000 cardiovascular deaths per year in nonsmokers. In addition, the risk of CVD decreases with the cessation of exposure to smoking. Association of smoking with CVD has been well known for years; however, association of secondhand smoke with CVD has been a topic of great interest, especially for the past 2 decades. Multiple studies and articles have evaluated the impact of smoking ban on the incidence of AMI-related hospitalizations. In this article, we discuss the effect of smoking ban on the economy and on human health in general, as well as its potential effects on the prevalence of smoking.

Surgical site infection (SSI) after a cesarean section increases maternal morbidity prolongs hospital stay and medical costs. The aim of this study was to find out the incidence and associated risk factors of surgical site infection among cesarean section cases. A prospective, descriptive study was conducted at Dhulikhel Hospital, department of Obstetrics and Gynaecology from July 2013 to June 2014. Total of 648 women who underwent surgical procedure for delivery during study period were included in the study. Data was collected from patient using structred pro forma and examination of wound till discharge was done. Data was compared in terms of presence of surgical site infection and study variables. Wound was evaluated for the development of SSI on third day, and fifth post-operative day, and on the day of discharge. Total of 648 cases were studied. The mean age was 24±4.18. Among the studied cases 92% were literate and 8% were illiterate. Antenatal clinic was attended by 97.7%. The incidence rate of surgical site infection was 82 (12.6%). SSI was found to be common in women who had rupture of membrane before surgery (p=0.020), who underwent emergency surgery (p=0.0004), and the women who had vertical skin incision (p=0.0001) and interrupted skin suturing (p=0.0001) during surgery. Surgical site infection following caesarean section is common. Various modifiable risk factors were observed in this study. Development of SSI is related to multifactorial rather than one factor. Development and strict implementation of protocol by all the health care professionals could be effective to minimize and prevent the infection rate after caesarean section.

    Persistent postoperative pain (PPP) is defined as persistent pain after surgery of greater than three months' duration. Identify the incidence of PPP in our hospital and its associated factors; evaluate quality of life (QoL) and treatment of patients. We conducted an observational prospective study in adults proposed to various types of surgery using the brief pain inventory short form preoperatively (T0), one day after surgery, and three months later (T3). If the patient had pain at T3 and other causes of pain were excluded, they were considered to have PPP, and the McGill Pain Questionnaire Short Form was applied. QoL was measured with the EuroQol 5-dimension questionnaire (EQ-5D). One hundred seventy-five patients completed the study. The incidence of PPP was 28%, and the affected patients presented lower QoL. The majority referred to a moderate to severe level of interference in their general activity. Cholecystectomies were less associated with PPP, and total knee/hip replacements were more associated with it. Preoperative pain, preoperative benzodiazepines or antidepressants, and more severe acute postoperative pain were associated with the development of PPP. Half of the patients with PPP were under treatment, and they refer a mean symptomatic relief of 69%. This study, apart from attempting to better characterize the problem of PPP, emphasizes the lack of its treatment.

    The medical/surgical hospital environment presents numerous challenges to a Critical Incident Stress Management (CISM) Team Coordinator responsible for implementing a psychological crisis intervention. Often this person is responsible for managing a response to a large in-house multiple-casualty incident, sometimes involving fatalities. Many mental health professionals have not had the opportunity to work in a medical/surgical healthcare facility and consequently are not familiar with the environment (and agency culture) that exists within these employment settings. This article will review important factors to be considered during the initial assessment of a critical incident in a hospital setting, logistical concerns that are unique to this setting, and the subsequent planning of the Critical Incident Stress Management Team crisis management response.

    To investigate the underlying causes of intravenous medication administration errors (MAEs) in National Health Service (NHS) hospitals. Two NHS teaching hospitals in the North West of England. Twenty nurses working in a range of inpatient clinical environments were identified and recruited using purposive sampling at each study site. Semistructured interviews were conducted with nurse participants using the critical incident technique, where they were asked to discuss perceived causes of intravenous MAEs that they had been directly involved with. Transcribed interviews were analysed using the Framework approach and emerging themes were categorised according to Reason's model of accident causation. In total, 21 intravenous MAEs were discussed containing 23 individual active failures which included slips and lapses (n=11), mistakes (n=8) and deliberate violations of policy (n=4). Each active failure was associated with a range of error and violation provoking conditions. The working environment was implicated when nurses lacked healthcare team support and/or were exposed to a perceived increased workload during ward rounds, shift changes or emergencies. Nurses frequently reported that the quality of intravenous dose-checking activities was compromised due to high perceived workload and working relationships. Nurses described using approaches such as subconscious functioning and prioritising to manage their duties, which at times contributed to errors. Complex interactions between active and latent failures can lead to intravenous MAEs in hospitals. Future interventions may need to be multimodal in design in order to mitigate these risks and reduce the burden of intravenous MAEs. Published by the BMJ Publishing Group Limited.

    Hospital-acquired pneumonia (HAP) is associated with high mortality and is the second most common nosocomial infection. The aim of this study was to calculate the incidence and to identify potential risk factors for HAP in an emergency ward for surgical patients admitted because of acute abdomen or trauma. A structured review of medical records was conducted. Patients diagnosed with pneumonia >48 h after admittance, were compared with a randomly chosen age-matched reference group. Ten variables judged as potential risk factors for HAP were studied in 90 patients. An emergency ward for surgical patients with acute abdomen or trauma at an Univerity hospital in Sweden. A total of 90 patients with HAP and 120 age-matched controls were included. Risk factors for HAP in patients at a surgical clinic. Of a total of 10 335 admitted patients, during 4.5 years the hospital stay was longer than 48 h in 4961 patients. Of these 90 (1.8%) fulfilled the strict criteria for HAP. Potential risk factors were suspected or verified aspiration (odds ratio (OR): 23.9) that was 2-fold higher than immobilization (OR: 11.2). Further, chronic pulmonary obstructive disease (COPD)/asthma, abdominal surgery and gastric retention/vomiting were risk factors for HAP. Verified or suspected aspiration was the dominating risk factor for HAP but also immobilization was frequently associated with HAP. Various established preventive measures should be implemented in the nursing care to reduce the frequency of HAP. © The Author 2017.

    To estimate the risk of influenza transmission in patients coming to a hospital emergency department during the week of highest incidence and to analyze factors associated with transmission. Retrospective observational analysis of a cohort of patients treated in the emergency room during the 2014-2015 flu season. The following variables were collected from records: recorded influenza diagnosis, results of a rapid influenza confirmation test, point of exposure (emergency department, outpatient clinic, or the community), age, sex, flu vaccination or not, number of emergency visits, time spent in the waiting room, and total time in the hospital. We compiled descriptive statistics and performed bivariate and multivariate analyses by means of a Poisson regression to estimate relative risk (RR) and 95% CIs. The emergency department patients had a RR of contracting influenza 3.29 times that of the communityexposed population (95% CI, 1.53-7.08, P=.002); their risk was 2.05 times greater than that of outpatient clinic visitors (95% CI, 1.04-4.02, P=.036). Emergency patients under the age of 15 years had a 5.27 greater risk than older patients (95% CI, 1.59-17.51; P=.007). The RR of patients visiting more than once was 11.43 times greater (95% CI, 3.58-36.44; P<.001). The risk attributable to visiting the emergency department risk was 70.5%, whereas risk attributable to community exposure was 2%. The risk of contracting influenza is greater for emergency department patients than for the general population or for patients coming to the hospital for outpatient clinic visits. Patients under the age of 15 years incur greater risk.

    The identification of an objective evaluation of frailty capable of predicting adverse outcomes in Alzheimer's disease is increasingly discussed. The purpose of this study was to investigate whether the Frailty Index (FI) predicts hospitalization, institutionalization, and mortality in Alzheimer's disease patients. A prospective multicenter cohort study (follow-up = 2 years) that included 1,191 participants with Alzheimer's disease was carried out. The outcomes of interest were incident hospitalization, institutionalization, and mortality. The FI was calculated as the ratio of actual to thirty potential deficits, that is, deficits presented by the participant divided by 30. Severity of dementia was assessed using the Clinical Dementia Rating score. Cox proportional hazard models were performed. Mean age of the study sample was 76.2 (SD = 7.6) years. A quadratic relationship of the FI with age was reported at baseline (R (2) = .045, p institutionalization. When the Clinical Dementia Rating score was simultaneously included in the age- and gender-adjusted models, the FI confirmed its predictive capacity for hospitalization (HR = 1.019, 95% CI = 1.006-1.032, p = .004), whereas the Clinical Dementia Rating score was the strongest predictor for mortality (HR = 1.922, 95% CI = 1.256-2.941, p = .003) and institutionalization (HR = 1.955, 95%CI = 1.427-2.679, p < .001). The FI is a robust predictor of adverse outcomes even after the stage of the underlying dementia is considered. Future work should evaluate the clinical implementation of the FI in the assessment of demented individuals in order to improve the personalization of care. © The Author 2015.

    Purpose: To characterize patterns in incidence, management, and costs of malignant spinal cord compression (MSCC) hospitalizations in the United States, using population-based data. Methods and Materials: Using the Nationwide Inpatient Sample, an all-payer healthcare database representative of all U.S. hospitalizations, MSCC-related hospitalizations were identified for the period 1998-2006. Cases were combined with age-adjusted Surveillance, Epidemiology and End Results cancer death data to estimate annual incidence. Linear regression characterized trends in patient, treatment, and hospital characteristics, costs, and outcomes. Logistic regression was used to examine inpatient treatment (radiotherapy [RT], surgery, or neither) by hospital characteristics and year, adjusting for confounding. Results: We identified 15,367 MSCC-related cases, representing 75,876 hospitalizations. Lung cancer (24.9%), prostate cancer (16.2%), and multiple myeloma (11.1%) were the most prevalent underlying cancer diagnoses. The annual incidence of MSCC hospitalization among patients dying of cancer was 3.4%; multiple myeloma (15.0%), Hodgkin and non-Hodgkin lymphomas (13.9%), and prostate cancer (5.5%) exhibited the highest cancer-specific incidence. Over the study period, inpatient RT for MSCC decreased (odds ratio [OR] 0.68, 95% confidence interval [CI] 0.61-0.81), whereas surgery increased (OR 1.48, 95% CI 1.17-1.84). Hospitalization costs for MSCC increased (5.3% per year, p < 0.001). Odds of inpatient RT were greater at teaching hospitals (OR 1.41, 95% CI 1.19-1.67), whereas odds of surgery were greater at urban institutions (OR 1.82, 95% CI 1.29-2.58). Conclusions: In the United States, patients dying of cancer have an estimated 3.4% annual incidence of MSCC requiring hospitalization. Inpatient management of MSCC varied over time and by hospital characteristics, with hospitalization costs increasing. Future studies are required to determine the impact of treatment patterns on MSCC

    The aim of this paper is to discover the aggregated results of a general notification system for incidents related to patient safety implemented in Catalan hospitals from 2010 to 2013. Observational study describing the incidents notified from January 2010 to December 2013 from all hospitals in Catalonia forming part of the project to create operational patient safety management units. The Patient Safety Notification and Learning System (SiNASP) was used. This makes it possible to classify incidents depending on the area where they occur, the type of incident notified, the consequences, the seriousness according to the Severity Assessment Code (SAC) and the profession of the notifying party, as the principal variables. The system was accessed via the Internet (SiNASP portal). Access was voluntary and anonymous or with a name given and later removed. During the study period, notification of a total of 5,948 incidents came from 22-29 hospitals. 5,244 of the incidents were handled by the centres and these are the ones analysed in the study. 64% (3,380) affected patients, 18% (950) created a situation capable of causing an incident and 18% (914) did not affect patients. 26% of incidents that affected patients (864) caused some kind of harm. Most incidents occurred during hospitalisation (54%) and in casualty (15%), followed by the ICU (9%) and the surgical block (8%). The most frequent notifying parties were nurses (71%) followed by doctors (15%) and pharmacists (9%). In terms of severity, most incidents were classified as low-risk (37%) or incidents that did not affect the patient (36%). However, 40 cases (0.76%) of extreme risk should be highlighted. In terms of the types of incident notified, most were due to a medication error (26.8%), followed by falls (16.3%) and patient identification (10.6%). The majority of notifications were incidents that affected patients and, of these, 26% caused harm. In general, they occurred in hospitalisation units and notification was

    Conclusion: On the basis of our findings, we conclude that AD may increase the incidence of hospitalization due to falls and bone fracture. We also found that AD has no effect on fracture location, but larger studies are needed to confirm this finding. Physicians and family members should emphasize the possibility of falls and bone fracture in patients with AD. Our findings suggest that preventing falls in AD patients may reduce the number of hospitalized AD patients.

    Full Text Available Little is known about the epidemiology of nosocomial bloodstream infections in public hospitals in developing countries. We evaluated trends in incidence of hospital-acquired bacteremia (HAB and healthcare-associated bacteremia (HCAB and associated mortality in a developing country using routinely available databases.Information from the microbiology and hospital databases of 10 provincial hospitals in northeast Thailand was linked with the national death registry for 2004-2010. Bacteremia was considered hospital-acquired if detected after the first two days of hospital admission, and healthcare-associated if detected within two days of hospital admission with a prior inpatient episode in the preceding 30 days.A total of 3,424 patients out of 1,069,443 at risk developed HAB and 2,184 out of 119,286 at risk had HCAB. Of these 1,559 (45.5% and 913 (41.8% died within 30 days, respectively. Between 2004 and 2010, the incidence rate of HAB increased from 0.6 to 0.8 per 1,000 patient-days at risk (p<0.001, and the cumulative incidence of HCAB increased from 1.2 to 2.0 per 100 readmissions (p<0.001. The most common causes of HAB were Acinetobacter spp. (16.2%, Klebsiella pneumoniae (13.9%, and Staphylococcus aureus (13.9%, while those of HCAB were Escherichia coli (26.3%, S. aureus (14.0%, and K. pneumoniae (9.7%. There was an overall increase over time in the proportions of ESBL-producing E. coli causing HAB and HCAB.This study demonstrates a high and increasing incidence of HAB and HCAB in provincial hospitals in northeast Thailand, increasing proportions of ESBL-producing isolates, and very high associated mortality.

    Hospital mortality is increasingly being regarded as a key indicator of patient safety, yet methodologies for assessing mortality are frequently contested and seldom point directly to areas of risk and solutions. The aim of our study was to classify reports of deaths due to unsafe care into broad areas of systemic failure capable of being addressed by stronger policies, procedures, and practices. The deaths were reported to a patient safety incident reporting system after mandatory reporting of such incidents was introduced. The UK National Health Service database was searched for incidents resulting in a reported death of an adult over the period of the study. The study population comprised 2,010 incidents involving patients aged 16 y and over in acute hospital settings. Each incident report was reviewed by two of the authors, and, by scrutinising the structured information together with the free text, a main reason for the harm was identified and recorded as one of 18 incident types. These incident types were then aggregated into six areas of apparent systemic failure: mismanagement of deterioration (35%), failure of prevention (26%), deficient checking and oversight (11%), dysfunctional patient flow (10%), equipment-related errors (6%), and other (12%). The most common incident types were failure to act on or recognise deterioration (23%), inpatient falls (10%), healthcare-associated infections (10%), unexpected per-operative death (6%), and poor or inadequate handover (5%). Analysis of these 2,010 fatal incidents reveals patterns of issues that point to actionable areas for improvement. Our approach demonstrates the potential utility of patient safety incident reports in identifying areas of service failure and highlights opportunities for corrective action to save lives.

    The incidence and management of hepatic adenoma at the Hospital Calderon Guardia are analyzed between the years 2002-2006. The main hepatic pathologies diagnosed by biopsy are shown. The relationship of hepatic adenoma with the above risk factors and presentation of each case of hepatic adenoma found are analyzed. The media diagnosed in this type of pathology were investigated. The evolution and control of each case of hepatic adenoma have been studied. The results of the management of each case are compared with the recommended in literature. The ideal management of this type of pathology is analyzed. Among the conclusions is given benign liver pathology as the most frequent cause of liver biopsy in the Hospital Calderon Guardia. Metastatic disease of the digestive tract has been the primary neoplastic disease at the hepatic level. Focal nodular hyperplasia has been the biopsy of benign tumor that is performed more frequently. Hepatic adenoma has been a rare entity, but with significant mortality rates. All cases were presented as solitary lesions. It is more common in women of childbearing age but can occur also in older people and in men. A close relationship has existed between the use of oral gestagens and the incidence of hepatic adenoma. Hepatic adenomas and its complications have been related to its size. Most cases of hepatic adenoma were presented with symptoms. The preoperative studies have shown high sensitivity in the detection of lesions, but little specificity. A protocol for the study of hepatic masses is required. A relationship between the size of the adenoma and possible complications was demonstrated. The reason for surgery in most cases has been the possibility of malignancy in the liver injury. The correlation between preoperative diagnosis and the end was unsuccessful in 75 percent of cases. The mortality related to the procedures did not exist, but if a case of morbidity. The study of liver masses should be more exhaustive to improve

    Full Text Available Background and Objectives. Hepatorenal syndrome carries a high risk of mortality. Understanding the incidence and mortality trends in hepatorenal syndrome will help inform future studies regarding the safety and efficacy of potential therapeutic interventions. Design and Methods. We conducted a retrospective cohort study using the Nationwide Inpatient Sample. We identified hospitalizations from January 1998–June 2011 with a primary diagnosis of hepatorenal syndrome. To characterize the incidence trends in monthly hepatorenal syndrome hospitalizations, we fit a piecewise linear model with a change point at January 2008. We examined hospital and patient characteristics before and after the change point. Results. Hospital admissions with a diagnosis of hepatorenal syndrome increased markedly between September of 2007 and March of 2008. Comparing patients who were admitted with a diagnosis of hepatorenal syndrome prior to 2008 with those after 2008, we found that length of stay increased while the mortality of patients admitted for hepatorenal syndrome decreased. Conclusion. The revision of the diagnostic criteria for hepatorenal syndrome may have contributed to the increase in the incidence of admissions for hepatorenal syndrome. However, the changes in the principles of hepatorenal syndrome management may have also contributed to the increase in incidence and lower mortality.

    Full Text Available Abstract Background Abdominal surgical site infections are among the most common complications of inpatient admissions and have serious consequences for outcomes and costs. Different risk factors may be involved, including age, sex, nutrition and immunity, prophylactic antibiotics, operation type and duration, type of shaving, and secondary infections. This study aimed to determine the risk factors affecting abdominal surgical site infections and their incidence at Imam Khomeini, a major referral teaching hospital in Iran. Methods Patients (n = 802 who had undergone abdominal surgery were studied and the relationships among variables were analyzed by Student's t and Chi-square tests. The subjects were followed for 30 days and by a 20-item questionnaire. Data were collected through pre- and post-operative examinations and telephone follow-ups. Results Of the 802 patients, 139 suffered from SSI (17.4%. In 40.8% of the cases, the wound was dirty infected. The average age for the patients was 46.7 years. The operations were elective in 75.7% of the cases and 24.7% were urgent. The average duration of the operation was 2.24 hours, the average duration of pre-operative hospital stay 4.31 days and the average length of (pre- and post-operation hospital stay 11.2 days. Three quarters of the cases were shaved 12 hours before the operation. The increased operation time, increased bed stay, electivity of the operation, septicity of the wound, type of incision, the administration of prophylactic antibiotic, type of operation, background disease, and the increased time lapse between shaving and operation all significantly associated with SSI with a p-value less than 0.001. Conclusion In view of the high rate of SSI reported here (17.4% compared with the 14% quoted in literature, this study suggests that by reducing the average operation time to less than 2 hours, the average preoperative stay to 4 days and the overall stay to less than 11 days, and

    This retrospective analysis reviews the clinical experience of a major urban referral hospital with diffuse malignant pleural mesothelioma during the 14-year period from 1973 through 1986. Seventy-five cases of definite or equivocal mesothelioma were identified. There were four cases of primary malignant peritoneal mesothelioma, seven cases of benign fibrous mesothelioma, and 64 cases of diffuse malignant pleural mesothelioma. In 43 cases (67%) of diffuse malignant pleural mesothelioma, there was historic evidence of asbestos exposure. In 21 cases (33%), there was no known history of asbestos exposure. An increase in annual incidence of diffuse malignant pleural mesothelioma was observed over the study period, from three cases in 1973 to ten cases in 1986. Despite greater awareness of this disease, the diagnosis remains a difficult one to establish given the nonspecific symptoms, signs and radiographic appearance, variable histologic appearance, and poor diagnostic sensitivity and specificity of thoracentesis and closed pleural biopsy. Thoracotomy, thoracoscopy, and CT-guided needle biopsies gave higher yields and are the diagnostic measures of choice when diffuse malignant pleural mesothelioma is suspected

    To estimate the incidence of emergency peripartum hysterectomy over 6 years in Ain-shams University Maternity Hospital. Detailed chart review of all cases of emergency peripartum hysterectomy, 2003-2008, including previous obstetric history, details of the index pregnancy, indications for emergency peripartum hysterectomy, outcome of the hysterectomy and infant morbidity. The overall rate of emergency peripartum hysterectomy was 149 of 66,306 or 2.24 per 1,000 deliveries. The primary indications for hysterectomies were placenta accreta/increta 59 (39.6 %), uterine atony 37 (24.8 %), uterine rupture 35 (23.5 %) and placenta previa without accreta 18 (12.1 %). After hysterectomy, 115 (77 %) women were admitted to the intensive care unit. Women were discharged home after a mean 11.2 day length of stay. Using multifactorial logistic regression analysis, we found that woman's age, atonic uterus, placenta accreta/increta, previous cesarian section and ruptured uterus were independent predictors for peripartum hysterectomy Abnormal placentation was the main indication for peripartum hysterectomy. The risk factors for peripartum hysterectomy were morbid adherence of placentae in scared uteri, uterine atony and uterine rupture. The most important step in prevention of major postpartum hemorrhage is recognizing and assessing women's risk. The risk of peripartum hysterectomy seems to be significantly decreased by limiting the number of cesarean section deliveries, thus reducing the occurrence of abnormal placentation in the form of placenta accreta, increta or percreta.

    Full Text Available BACKGROUND: There is a knowledge gap with relation to the true incidence of deep vein thrombosis among patients undergoing vascular surgery procedures in Brazil. This study is designed to support the implementation of a surveillance system to control the quality of venous thromboembolism prophylaxis in our country. Investigations in specific institutions have determined the true incidence of deep vein thrombosis and identified risk groups, to enable measures to be taken to ensure adequate prophylaxis and treatment to prevent the condition.OBJECTIVE: To study the incidence of deep venous thrombosis in patients admitted to hospital for non-venous vascular surgery procedures and stratify them into risk groups.METHOD: This was a cross-sectional observational study that evaluated 202 patients from a university hospital vascular surgery clinic between March 2011 and July 2012. The incidence of deep venous thrombosis was determined using vascular ultrasound examinations and the Caprini scale.RESULTS: The mean incidence of deep venous thrombosis in vascular surgery patients was 8.5%. The frequency distribution of patients by venous thromboembolism risk groups was as follows: 8.4% were considered low risk, 17.3% moderate risk, 29.7% high risk and 44.6% were classified as very high risk.CONCLUSION: The incidence of deep venous thrombosis in vascular surgery patients was 8.5%, which is similar to figures reported in the international literature. Most vascular surgery patients were stratified into the high and very high risk for deep venous thrombosis groups.

    Full Text Available Abstract Background Carpal tunnel syndrome (CTS is a socially relevant condition associated with biomechanical risk factors. We evaluated age-sex-specific incidence rates of in-hospital cases of CTS in central/northern Italy and explored relations with marital status. Methods Seven regions were considered (overall population, 14.9 million over 3–6-year periods between 1997 and 2002 (when out-of-hospital CTS surgery was extremely rare. Incidence rates of in-hospital cases of CTS were estimated based on 1 codified demographic, diagnostic and intervention data in obligatory discharge records from all Italian public/private hospitals, archived (according to residence on regional databases; 2 demographic general population data for each region. We compared (using the χscore test age-sex-specific rates between married, unmarried, divorced and widowed subsets of the general population. We calculated standardized incidence ratios (SIRs for married/unmarried men and women. Results Age-standardized incidence rates (per 100,000 person-years of in-hospital cases of CTS were 166 in women and 44 in men (106 overall. Married subjects of both sexes showed higher age-specific rates with respect to unmarried men/women. SIRs were calculated comparing married vs unmarried rates of both sexes: 1.59 (95% confidence interval [95% CI], 1.57–1.60 in women, and 1.42 (95% CI, 1.40–1.45 in men. As compared with married women/men, widows/widowers both showed 2–3-fold higher incidence peaks during the fourth decade of life (beyond 50 years of age, widowed subjects showed similar trends to unmarried counterparts. Conclusion This large population-based study illustrates distinct age-related trends in men and women, and also raises the question whether marital status could be associated with CTS in the general population.

    To identify the incidence, causes, timing and risk factors associated with 1-year mortality in CAP patients after hospital discharge. Adult patients with CAP who were admitted to a tertiary hospital from 2007 to 2011 were prospectively recruited and followed up for 1 year after hospital discharge. Of the 1284 patients discharged, 93 (7.2%) died within 1-year of leaving hospital. Sixty eight (73.1%) patients died in the first six months. The main reasons for 1-year mortality after hospital discharge were infectious diseases, mainly pneumonia, followed by acute cardiovascular events. Mortality from infectious diseases was higher during the first 6 months (86.1%), while the number of deaths from cardiovascular causes was stable throughout the months of follow-up. After adjustment for confounders, chronic obstructive pulmonary disease, diabetes mellitus, cancer, dementia, rehospitalization within 30 days of hospital discharge and nursing home were independently associated with 1-year mortality. The incidence of long-term mortality increased >50% when ≥4 risk factors were present (P risk of long-term mortality in CAP patients. Copyright © 2014 The British Infection Association.

    Prehospital and hospital care during incidents of mass violence and civil conflict involve a number of aspects that distinguish it from care during times of peace. We aimed to analyze the dynamics and outcomes of prehospital and hospital care during ongoing conflicts. Multicentric prospective observational study. Patients enrolled in the study, which was conducted in Turkey, were all injured in armed conflict and taken to level 1 trauma centers. On admittance, patients were requested to complete a semistructured questionnaire containing questions on patient demographics, transport type, weapons used, injury severity score (ISS), and other incident-related factors. We analyzed patient outcomes (mortality, morbidity, complications, and length of hospital stay) and transfers of patients between hospitals. The present study evaluated the cases of 390 victims enrolled over a 9-month period and followed up for 6 months. The majority of patients were transported by ambulances (n = 334, 85.6%); other transport modes were helicopters (n = 32, 8.2%) and private vehicles (n = 24, 6.2%). Nearly half of patients (48.7%) did not benefit by changing hospitals. During transport to hospitals, 4.1% of the vehicles in the study were involved in accidents. Using multiple regression analysis, only ISS (odds ratio [OR]: 1.098, 95% confidence interval [CI]: 1.044-1.156) and the Glasgow Coma Scale (OR: 0.744, 95% CI: 0.639-0.866) were found to affect mortality. In Receiver-operator characteristic analysis, a cutoff value of 22.5 for ISS had a sensitivity of 100% and a specificity of 89.6% for mortality. Despite lower ISS values, patient outcomes were worse in terror incidents/civil conflicts. Transport modes did not significantly affect outcomes, whereas hospital transport was found to be inefficiently used. Copyright © 2017 The Royal Society for Public Health. Published by Elsevier Ltd.

    We reviewed patients with critical incidents that occurred in the post-anaesthesia care unit (PACU) at a major tertiary hospital, and assessed the effect of these incidents on PACU length of stay and discharge disposition. A retrospective review was conducted of patients in the PACU over a two-year period from 24 June 2011 to 23 August 2013. Data on critical incidents was recorded in the administrative database using a standardised data form. There were 701 incidents involving 364 patients; 203 (55.8%) patients had American Society of Anesthesiologists (ASA) physical status I or II. The most common critical incidents were cardiovascular-related (n = 293, 41.8%), respiratory (n = 155, 22.1%), neurological (n = 52, 7.4%), surgical (n = 47, 6.7%) and airway-related (n = 34, 4.9%). There were two incidents of cardiac arrest and 25 incidents of unexpected reintubations. Many patients (n = 186, 51.2%) stayed for over four hours in the PACU due to critical incidents and 184 (50.5%) patients required a higher level of care postoperatively than initially planned. Some patients (n = 34, 9.3%) returned to the operation theatre for further management. A proportion of patients (n = 64, 17.6%) had unplanned intensive care unit admissions due to adverse events in the PACU. A wide spectrum of critical incidents occur in the PACU, many of which are related to the cardiovascular and respiratory systems. Critical incidents have a major impact on healthcare utilisation and result in prolonged PACU stays and higher levels of postoperative care than initially anticipated.

    When patient safety programs were mandated for Japanese health care institutions, a safety culture, a tool for collecting incident reports, an organizational arrangement for multidisciplinary collaboration, and interventional methods for improvement had to be established. Observational study of effects of new patient safety programs. Osaka University Hospital, a large government-run teaching hospital. A voluntary and anonymous web-based incident reporting system was introduced. For the new organizational structure a clinical risk management committee, a department of clinical quality management, and area clinical risk managers were established with their respective roles clearly defined to advance the plan-do-study-act cycle and to integrate efforts. For preventive action, alert procedures, staff education, ward rounds by peers, a system oriented approach for reducing errors, and various feedback channels were introduced. Continuous incident reporting by all hospital staff has been observed since the introduction of the new system. Several error inducing situations have been improved: wrong choice of drug in computer prescribing, maladministration of drugs due to a look-alike appearance or confusion about the manipulation of a medical device, and poor after hours service of the blood transfusion unit. Staff participation in educational seminars has been dramatically improved. Ward rounds have detected problematic procedures which needed to be dealt with. Patient safety programs based on a web-based incident reporting system, responsible persons, staff education, and a variety of feedback procedures can help promote a safety culture, multidisciplinary collaboration, and strong managerial leadership resulting in system oriented improvement.

    The aim of the study was to verify the effectiveness of short text messages (short message service, or SMS) as an additional notification tool in case of fire or a mass casualty incident in a hospital. A total of 2242 SMS text messages were sent to 59 hospital workers divided into 3 groups (n=21, n=19, n=19). Messages were sent from a Samsung GT-S8500 Wave cell phone and Orange Poland was chosen as the telecommunication provider. During a 3-month trial period, messages were sent between 3:35 PM and midnight with no regular pattern. Employees were asked to respond by telling how much time it would take them to reach the hospital in case of a mass casualty incident. The mean reaction time (SMS reply) was 36.41 minutes. The mean declared time of arrival to the hospital was 100.5 minutes. After excluding 10% of extreme values for declared arrival time, the mean arrival time was estimated as 38.35 minutes. Short text messages (SMS) can be considered an additional tool for notifying medical staff in case of a mass casualty incident.

    Concerns about healthcare-associated infections and the global crisis in antimicrobial resistance has combined to accentuate the fears around so-called "superbugs". In Ireland there is no single agreed indicator regarded as a true measure of the level of methicillin resistant Staphylococcus aureus (MRSA) in hospitals. The objective of this study was to compare two crude measures of MRSA--the percentage of bacteraemia caused by MRSA and the incidence rate (per 1000 bed days used) of MRSA bacteraemia in six acute hospitals. We examined all blood cultures positive for S. aureus (methicillin sensitive and resistant) from 2002 to 2004 in the Health Service Executive (HSE) Mid-Western Area of Ireland. Hospital In-Patient Enquiry (HIPE) data was used to determine monthly in-patient bed days used. Of 245 patient episodes of bacteraemia, 119 were MRSA. The trends in the percentage of isolates that were MRSA and the incidence rate calculated were compared. The incidence rate appears to be a more reliable and robust indicator of MRSA in hospitals than the percentage. Despite many difficulties in interpreting indicators of MRSA they should not preclude the regular publication of data at least at regional level in Ireland.

    Full Text Available Abstract Background Acute seizures are a common cause of paediatric admissions to hospitals in resource poor countries and a risk factor for neurological and cognitive impairment and epilepsy. We determined the incidence, aetiological factors and the immediate outcome of seizures in a rural malaria endemic area in coastal Kenya. Methods We recruited all children with and without seizures, aged 0–13 years and admitted to Kilifi District hospital over 2 years from 1st December 2004 to 30th November 2006. Only incident admissions from a defined area were included. Patients with epilepsy were excluded. The population denominator, the number of children in the community on 30th November 2005 (study midpoint, was modelled from a census data. Results Seizures were reported in 900/4,921(18.3% incident admissions and at least 98 had status epilepticus. The incidence of acute seizures in children 0–13 years was 425 (95%CI 386, 466 per 100,000/year and was 879 (95%CI 795, 968 per 100,000/year in children Conclusion There is a high incidence of acute seizures in children living in this malaria endemic area of Kenya. The most important causes are diseases that are preventable with available public health programs.

    Since the end of World War II, there has been an emergence of explosives used amongst civilian populations resulting in mass-casualty incidents. The development of pre-hospital medical systems, worldwide, has resulted in an increased response at these incidents. However, information about the pre-hospital medical response is sparse and not collated. This review aimed to collect and appraise the literature on the pre-hospital management of mass-casualty bombing incidents. The primary objective was to identify and discuss the common themes highlighted as problems in the pre-hospital medical response. The secondary objectives reviewed the injury patterns in victims and psychological impacts on pre-hospital responders. A systematic literature search on the PubMed, SCOPUS and Web of Science databases took place. It included literature published from the 1 st of January 2000 to April 3rd 2017, with the last search performed on April 3rd 2017. Literature was included if it offered description, analysis, reflection or review of the bombing incidents.emermed;34/12/A884-a/F1F1F1Figure 1The minimum number of recorded deaths and injuries from 11 deliberate mass casualty bombing incidents (note: two simultaneous marauding terrorist firearm attack and bombing incidents excluded)emermed;34/12/A884-a/F2F2F2Figure 2Percentage of included literature identifying the following themes as problems in the pre-hospitals medical response RESULTS: 1345 articles were found, with 54 included in analysis. 13 mass-casualty bombing incidents were described.

    Incidence of C-2 fracture is increasing in elderly patients. Patient age also influences decision making in the management of these fractures. There are very limited data on the national trends of incidence, treatment interventions, and resource utilization in patients in different age groups with isolated C-2 fractures. The aim of this study is to investigate the incidence, treatment, complications, length of stay, and hospital charges of isolated C-2 fracture in patients in 3 different age groups by using the Nationwide Inpatient Sample (NIS) database. The data were obtained from NIS from 2002 to 2011. Data on patients with closed fractures of C-2 without spinal cord injury were extracted using ICD-9-CM diagnosis code 805.02. Patients with isolated C-2 fractures were identified by excluding patients with other associated injuries. The cohort was divided into 3 age groups: 80 years. Incidence, treatment characteristics, inpatient/postoperative complications, and hospital charges (mean and total annual charges) were compared between the 3 age groups. A total of 10,336 patients with isolated C-2 fractures were identified. The majority of the patients were in the very elderly age group (> 80 years; 42.3%) followed by 29.7% in the 65- to 80-year age group and 28% in age group. From 2002 to 2011, the incidence of hospitalization significantly increased in the 65- to 80-year and > 80-year age groups (p age group (p = 0.287). Overall, 21% of the patients were treated surgically, and 12.2% of the patients underwent nonoperative interventions (halo and spinal traction). The rate of nonoperative interventions significantly decreased over time in all age groups (p age groups had a greater risk of inpatient/postoperative complications, nonroutine discharges, and longer hospitalization. The mean hospital charges were significantly higher in older age groups (p age groups. Simultaneously, there has been a steadily decreasing trend in the preference for nonoperative

    Full Text Available Introduction: The lack of knowledge regarding the incidence of adverse drug reactions in the hospital setting and their impact on morbidity and mortality is, nowadays, a major health problem in Angola. In the last years, notifications of adverse drug reactions have been practically null, namely at a hospital level. It is of great importance to characterize the incidence of adverse drug reactions occurring in a hospital setting, in order to implement measures towards improving the quality of healthcare services. Material and Methods: We conducted a descriptive, prospective observational study to characterize the incidence of adverse drug reactions (ADRs in patients admitted to the Central Hospital “Josina Machel” in Luanda during the year 2014. An intensive monitoring through active search for adverse reactions possibly related with the drugs prescribed to patients was performed. Results: Of a total of 2041 hospitalized patients, 175 had adverse drug reactions. The incidence rate was 4.74% in the medicine service (n = 1077 and 12.86% in the therapy service (n = 964. A total of 209 adverse drug reactions were identified, averaging 1,2 adverse drug reactions per patient. The highest incidence rate of adverse drug reactions was recorded in patients aged between 18 and 35 years old, with 79 patients (45.14%. With regard to therapeutic class, it was found that antimicrobials were the drugs most commonly associated with adverse reactions, with 71 notifications (40.57%, followed by analgesics, antipyretics and anti-inflammatory steroids with 20,00%. Quinine and artesunate were the antimicrobials most frequently implicated in causing an adverse drug reaction, with 25 (14.29% and 15 (8.57% notifications respectively. In the group of anti-inflammatory drugs, diclofenac stood out with 13 notifications (7.43%. The most common clinical manifestations were skin rash, which corresponded to 23,44% of the total number of adverse drug reactions, followed by

    A surveillance system for self-harm has not been established in Hong Kong. The existing data source has an unknown degree of underreporting, and therefore a capture-recapture method has been proposed to correct for the incompleteness. To assess the underestimation of the incidence of self-harm cases presenting to hospital in Hong Kong using a capture and recapture method. Two different yet overlapping hospital administrative datasets of self-harm were obtained from all public hospitals in Hong Kong. From 2002 to 2011, 59,473 distinct episodes involving 36,411 patients were identified. A capture-recapture model considering heterogeneous capture probabilities was applied to estimate the number of self-harm episodes. The estimated number of self-harm incidence was 79,923, equally shared by females and males. Cases of self-harm by females were more likely to be ascertained than those by males. The estimated annual incidence rate of self-harm in Hong Kong from 2002 to 2011 ranged from 96.4 in 2010 to 132.7 in 2002. The proposed method does not include patients who required no medical attention and those where the patient consulted private doctors. The capture-recapture model is a useful method for adjusting the underestimation of self-harm cases from existing databases when surveillance system is not available and to reveal some hidden patterns.

    Invasive pneumococcal disease causes substantial morbidity and mortality in Africa. Evaluating population level indirect impact on adult disease of pneumococcal conjugate vaccine (PCV) programmes in infants requires baseline population incidence rates but these are often lacking in areas with limited disease surveillance. We used hospital based blood culture and cerebrospinal fluid surveillance to calculate minimal incidence of invasive pneumococcal disease in the adult (≥15 years old) population of Blantyre, a rapidly growing urban centre in southern Malawi, in the period preceding vaccine introduction. Invasive pneumococcal disease incidence in Blantyre district was high, mean 58.1 (95% confidence interval (CI): 53.7, 62.7) per 100,000 person years and peaking among 35 to 40 year olds at 108.8 (95%CI: 89.0, 131.7) mirroring the population age prevalence of HIV infection. For pneumococcal bacteraemia in urban Blantyre, mean incidence was 60.6 (95% CI: 55.2, 66.5) per 100,000 person years, peaking among 35 to 40 year olds at 114.8 (95%CI: 90.3, 143.9). We suspected that our surveillance may under-ascertain the true burden of disease, so we used location data from bacteraemic subjects and projected population estimates to calculate local sub-district incidence, then examined the impact of community level socio-demographic covariates as possible predictors of local sub-district incidence of pneumococcal and non-pneumococcal pathogenic bacteraemia. Geographic heterogeneity in incidence was marked with localised hotspots but ward level covariates apart from prison were not associated with pneumococcal bacteraemia incidence. Modelling suggests that the current sentinel surveillance system under-ascertains the true burden of disease. We outline a number of challenges to surveillance for pneumococcal disease in our low-resource setting. Subsequent surveillance in the vaccine era will have to account for geographic heterogeneity when evaluating population level indirect

For pneumococcal bacteraemia in urban Blantyre, mean incidence was 60.6 (95% CI: 55.2, 66.5 per 100,000 person years, peaking among 35 to 40 year olds at 114.8 (95%CI: 90.3, 143.9. We suspected that our surveillance may under-ascertain the true burden of disease, so we used location data from bacteraemic subjects and projected population estimates to calculate local sub-district incidence, then examined the impact of community level socio-demographic covariates as possible predictors of local sub-district incidence of pneumococcal and non-pneumococcal pathogenic bacteraemia. Geographic heterogeneity in incidence was marked with localised hotspots but ward level covariates apart from prison were not associated with pneumococcal bacteraemia incidence. Modelling suggests that the current sentinel surveillance system under-ascertains the true burden of disease. We outline a number of challenges to surveillance for pneumococcal disease in our low-resource setting. Subsequent surveillance in the vaccine era will have to account for geographic heterogeneity when evaluating population

    Healthcare technology is meant to reduce medication errors. The objective of this study was to assess unintended errors related to technologies in the medication use process. Medication incidents reported from 2006 to 2010 in a main tertiary care hospital were analysed by a pharmacist and technology-related errors were identified. Technology-related errors were further classified as socio-technical errors and device errors. This analysis was conducted using data from medication incident reports which may represent only a small proportion of medication errors that actually takes place in a hospital. Hence, interpretation of results must be tentative. 1538 medication incidents were reported. 17.1% of all incidents were technology-related, of which only 1.9% were device errors, whereas most were socio-technical errors (98.1%). Of these, 61.2% were linked to computerised prescription order entry, 23.2% to bar-coded patient identification labels, 7.2% to infusion pumps, 6.8% to computer-aided dispensing label generation and 1.5% to other technologies. The immediate causes for technology-related errors included, poor interface between user and computer (68.1%), improper procedures or rule violations (22.1%), poor interface between user and infusion pump (4.9%), technical defects (1.9%) and others (3.0%). In 11.4% of the technology-related incidents, the error was detected after the drug had been administered. A considerable proportion of all incidents were technology-related. Most errors were due to socio-technical issues. Unintended and unanticipated errors may happen when using technologies. Therefore, when using technologies, system improvement, awareness, training and monitoring are needed to minimise medication errors. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Objectives: To identify and describe the hospital disaster preparedness (HDP in major private hospitals in Riyadh, Saudi Arabia. Methods: This is an observational cross-sectional survey study performed in Riyadh city, Saudi Arabia between December 2015 and April 2016. Thirteen major private hospitals in Riyadh with more than 100 beds capacity were included in this investigation. Results: The 13 hospitals had HDP plan and reported to have an HDP committee. In 12 (92.3% hospitals, the HDP covered both internal and external disasters and HDP was available in every department of the hospital. There were agreements with other hospitals to accept patients during disasters in 9 facilities (69.2% while 4 (30.8% did not have such agreement. None of the hospitals conducted any unannounced exercises in previous year. Conclusion: Most of the weaknesses were apparent particularly in the education, training and monitoring of the hospital staff to the preparedness for disaster emergency occasion. Few hospitals had conducted an exercise with casualties, few had drilled evacuation of staff and patients in the last 12 months, and none had any unannounced exercise in the last year.

    Full Text Available BACKGROUND: There has not been sufficient evidence to support the Asians being less susceptible to pulmonary embolism (PE than other ethnicities, because the prevalence of PE/deep venous thrombosis (DVT in different racial and ethnic groups has not been carefully studied until recently except in Caucasians. To test the hypothesis that the Chinese population has a lower risk for PE, this study comprehensively assessed the hospital-based incidence and case fatality rates for PE during the 1997-2008 in China. METHODS: A registration study of patients with suspected PE syndromes admitted to 60 level-3 hospitals involved in the National Cooperative Project for the Prevention and Treatment of Venous Thromboembolism (NCPPT was conducted from January 1997 to December 2008. The only exclusion criterion was an age of less than 18 years. Helical computed tomography scan, ventilation-perfusion lung scintigraphy or pulmonary angiography was carried out before or after hospitalization. All images were reviewed and evaluated independently by two specialists. RESULTS: A total of 18,206 patients were confirmed with PE from 16,972,182 hospital admissions. The annual incidence was 0.1% (95% CI: 0.1% to 0.2%. The overall incidence of PE in male patients (0.2%, 95% CI: 0.1% to 0.3% was higher than that in female patients (0.1% and 95% CI: 0.0% to 0.1%. An increasing incidence gradient for PE was noticed from Southern to Northern China. In addition, the case fatality rate was apparently decreasing: 25.1% (95% CI: 16.2% to 36.9% in 1997 to 8.7% (95% CI: 3.5% to 15.8% in 2008. CONCLUSIONS: Our findings suggest the relatively stable PE incidence and decreasing fatality trends in Chinese hospitals may be partially attributable to the implementation of the NCCPT and suggest the government should reevaluate the severity of PE so that health resources for the prevention, diagnosis and treatment of PE could be used to their fullest.

    The age-group-specific incidence and etiological patterns of community-acquired pneumonia (CAP) have not been fully established in Japan. A 2-year prospective surveillance was conducted in Kochi city, Western Japan. All CAP patients aged ≥15 years who visited a community-based hospital were enrolled in the study. Clinical samples were examined by conventional bacterial culture and urinary antigen tests, and 6 bacterial pathogens and 16 respiratory viruses were identified from sputum samples by multiplex polymerase chain reaction assays. The age-group-specific incidence of CAP was estimated using a population-based data set of the total number of outpatients in the whole city. Ninety of the 131 enrolled patients, 68.7% were positive for respiratory pathogens. Streptococcus pneumoniae was the leading bacterial pathogen identified (28.2%). Respiratory viruses were identified in 36 patients (27.5%), and human entero-rhinovirus was the most common (13.3%) among them. The estimated overall incidence of adult CAP in Kochi was 9.6 per 1,000 person-years (PY); the estimated age group-specific incidence was 3.4, 10.7, and 42.9 per 1,000 PY for those aged 15-64, 65-74, and ≥75 years, respectively. The high incidence of CAP in these rural city of Japan, probably reflects the substantial aged population. S. pneumoniae and respiratory viruses play important roles in CAP in all age groups.

    Background and Aims: Provision of effective and safe postoperative pain management is the principal responsibility of acute pain services (APSs). Continuous quality assurance is essential for high-quality patient care. We initiated anonymous reporting of critical incidents by APS to ensure continuous quality improvement and here present prospectively collected data on the reported incidents. Our objective was to analyze the frequency and nature of incidents and to see if any harm was caused to patients. Material and Methods: Data were collected from January 1, 2012 to September 30, 2013. An incident related to pain management was defined as An incident that occurs in a patient receiving pain management supervised by APS, and causes or has the potential to cause harm or affects patient safety. A form was filled including incident type, personnel involved, any harm caused, and steps taken to rectify it. Frequencies and percentages were computed for categorical variables. Results: A total of 2042 patients were seen and 442 (21.64%) incidents reported during the study period, including documentation errors (136/31%), noncompliance with protocols (113/25.56%), wrong combination of drugs (56/12.66%), premature discontinuation (74/16.72%), prolonged delays in change of syringes (27/6.10%), loss to follow-up (19/4.29%), administration of contraindicated drugs (9/2.03%), catheter pull-outs (6/1.35%), and faulty equipment (2/0.45%). Steps were taken to rectify the errors accordingly. No harm was caused to any patient. Conclusion: Reporting of untoward incidents and their regular analysis by APS is recommended to ensure high-quality patient care and to provide guidance in making teaching strategies and guidelines to improve patient safety.

    Full Text Available Objective: We analyzed the incidence of heparin-induced thrombocytopenia in a group of patients who received heparin (LMWH, UFH in an education and research hospital using the 4T test score as a diagnostic tool. Patients and Methods: A retrospective descriptive study analyzing patients using heparin preparations within the years 2015 and 2016. The risk for heparin-induced thrombocytopenia was calculated using the 4T test score system and also the monitoring of platelet counts of each patient. Results: Of 19.257 patients who used either UFH or LMWH and were admitted to the hospital within 2015 and 2016, 308 patients were suspected to have thrombocytopenia based on their individual platelet counts by excluding only patients with thrombocytopenia. 100 patients were determined to probably have heparin-induced thrombocytopenia and were further evaluated using the 4t test score. Overall risk was calculated to be 0.5%. Incidence was calculated to be 0.15% (29 out of 19257. For patients with high-risk scores, the incidence was 0.01% (2 out of 19257. Patients who had a high 4T test score were using ranitidine. In 29 patients who had intermediate and high-risk probability for HIT, mean starting day of HIT was 6.24±3.68 days; mean withdrawal day of heparin was 9,55±5,86 days and mean delay of heparin withdrawal was 3.31±3.39 days. Conclusion: Although the use of LMWH is being favored in the hospital when compared to UFH, health care practitioners should still remain vigilant about the occurrence of HIT as a complication of heparin therapy in hospitalized patients most especially within the first few weeks following heparin administration.

    Full Text Available Background: Patients in the intensive care unit (ICU have impaired ocular protective mechanisms that lead to an increased risk of ocular surface diseases including exposure keratopathy (EK. This study was designed to evaluate the effect of normal saline (NS on the incidence and severity of EK in critically ill patients. Materials and Methods: This single-blind randomized controlled trial was conducted on 50 patients admitted to ICUs. The participants were selected through purposive sampling. One eye of each patient, randomly was allocated to intervention group (standard care with NS and the other eye to control group (standard care. In each patient, one eye (control group randomly received standard care and the other eye (intervention group received NS every 6 h in addition to standard care. The presence and severity of keratopathy was assessed daily until day 7 of hospitalization using fluorescein and an ophthalmoscope with cobalt blue filter. Chi-square test was used for statistical analysis in SPSS software. Results: Before the study ( first day there were no statistically significant differences in the incidence and severity of EK between groups. Although, the incidence and severity of EK after the study (7th day was higher in the intervention group compared to the control group, their differences were not statistically significant. Although, the incidence and severity of EK, from the 1st day until the 7th, increased within both groups, this increase was statistically significant only in the intervention (NS group. Conclusions: The use of NS as eye care in patients hospitalized in ICUs can increase the incidence and severity of EK and is not recommended.

    Human metapneumovirus (HMPV) causes acute respiratory tract infections in infants and children. We sought to measure the clinical and economic burden of HMPV infection in hospitalized children. We conducted a retrospective cohort study from 2007 to 2013 at Primary Children's Hospital in Salt Lake City, Utah. Children <18 years of age with laboratory-confirmed HMPV infection were included. Demographic, clinical, and financial data were abstracted from the electronic medical record. During the study period, 815 children were hospitalized with laboratory-confirmed HMPV infection: 16% <6 months, 50% 6-23 months, 23% 2-4 years, and 11% 5-17 years of age. A complex chronic condition was identified in 453 (56%) children hospitalized with HMPV infection; this proportion increased with increasing age (P < .001). There was marked variation in annual HMPV hospitalization rates, ranging from 9 of 100 000 person-years in 2012-2013 to 79 of 100 000 in 2009-2010. Hospitalization rates were highest among children <2 years (200 of 100 000 person-years) and lowest among children 5-17 years of age (5 of 100 000). Of hospitalized children, 18% were treated in the intensive care unit and 6% required mechanical ventilation. The median length of stay was 2.8 days (interquartile range [IQR], 1.8-4.6) and did not vary by age. The median total hospital cost per patient was $5513 (IQR, $3850-$9946) with significantly higher costs for patients with chronic medical conditions (P < .001). Human metapneumovirus infection results in a large number of hospitalizations with substantial morbidity, resource utilization, and costs. The development of a safe and effective vaccine could reduce the clinical and economic burden of HMPV. © The Author 2015.

    Many children become infected with Epstein-Barr virus (EBV) during their childhood. Since the clinical profile of EBV primary infection is challenging, it is important to use the best diagnostic clinical means. Detection of IgM against viral capsid antigen (VCA) by ELISA has been shown to be a reliable method. This study was conducted to demonstrate the incidence of EBV primary infection, among suspected patients referred to Namazi hospital, Shiraz, Iran. The sample included 346 patients with an age range of 0 to 20 years (6.31 ± 4.66: 10.97 years). A volume of 5 mL of blood was collected from each case. The patients were divided to four age groups. The sera were tested for the presence of VCA-IgM by commercially available Anti-EBV-VCA ELISA kit. The results indicated that 104 (30.0%) of the patients were EBV VCA IgM positive, with no significant difference in the incidence of EBV primary infection between males and females. However, the incidence of infection was significantly different between age group I (0 - 5 years) and III (11 - 15 years), and also between age group I (0 - 5 years) and IV (16 - 20 years) (P < 0.05). Considering the results, accurate and on time diagnosis of EBV primary infection in both children and adolescents will help prevent unnecessary hospitalization, medication and incorrect medical decisions. In addition, this will decrease further treatment costs and related medical procedures.

    Full Text Available Background: In this study, the patients who were operated in two clinics due to traumatic cranial epidural hematoma (EDH were assessed retrospectively and the factors that increase the costs were tried to be revealed through conducting cost analyses. Methods: The patients who were operated between 2010 and 2016 with the diagnosis of EDH were assessed in terms of age, sex, trauma etiology, Glasgow coma scale (GCS at admission, the period from trauma to hospital arrival, trauma-related injury in other organs, the localization of hematoma, the size of hematoma, length of stay in the intensive care unit (ICU, length of antibiotherapy administration, number of consultations conducted, total cost of in-hospital treatments of the patients and prognosis. Results: Distribution of GCS were, between 13-15 in 18 (36% patients, 9-13 in 23 (46% patients and 3-8 in 9 (18% patients. The reasons for emergency department admissions were fall from high in 29 (58% patients, assault in 11 (22% patients and motor vehicle accident in 10 (20% patients. The average cost per ICU stay was 2838 $ (range=343-20571 $. The average cost per surgical treatment was 314 $. ICU care was approximately 9 times more expensive than surgical treatment costs. The mortality rate of the study cohort was 14% (7 patients. Conclusion: The prolonged period of stay in the ICU, antibiotherapy and repeat head CTs increase the costs for patients who are surgically treated for EDH.

    The objective is to assess the safety, tolerability, and efficacy of sacubitril/valsartan compared with enalapril in patients with heart failure (HF) with a reduced ejection fraction (EF) stabilized during hospitalization for acute decompensated HF. Sacubitril/valsartan, a first-in-class angiotensin receptor-neprilysin inhibitor, improves survival among ambulatory HF patients with a reduced EF. However, there is very limited experience with the in-hospital initiation of sacubitril/valsartan in patients who have been stabilized following hospitalization for acute decompensated HF. PIONEER-HF is a 12-week, prospective, multicenter, double-blind, randomized controlled trial enrolling a planned 882 patients at more than 100 participating sites in the United States. Medically stable patients >18 years of age with an EF 1600 pg/mL or b-type natriuretic peptide >400 pg/mL are eligible for participation no earlier than 24 hours and up to 10 days from initial presentation while still hospitalized. Patients are randomly assigned 1:1 to in-hospital initiation of sacubitril/valsartan titrated to 97/103 mg by mouth twice daily versus enalapril titrated to 10 mg by mouth twice daily for 8 weeks. All patients receive open-label treatment with sacubitril/valsartan for the remaining 4 weeks of the study. The primary efficacy end point is the time-averaged proportional change in amino terminal-pro b-type natriuretic peptide from baseline through weeks 4 and 8. Secondary and exploratory end points include serum and urinary biomarkers as well as clinical outcomes. Safety end points include the incidence of angioedema, hypotension, renal insufficiency, and hyperkalemia. The PIONEER-HF trial will inform clinical practice by providing evidence on the safety, tolerability, and efficacy of in-hospital initiation of sacubitril/valsartan among patients who have been stabilized following an admission for acute decompensated HF with a reduced EF.

    This study sought to examine the relationships between in-hospital and post-discharge body weight changes and outcomes among patients hospitalized for acute heart failure (AHF). Body weight changes during and after hospitalization for AHF and the relationships with outcomes have not been well characterized. A post hoc analysis was performed of the ASCEND-HF (Acute Study of Clinical Effectiveness of Nesiritide and Decompensated Heart Failure) trial, which enrolled patients admitted for AHF regardless of ejection fraction. In-hospital body weight change was defined as the difference between baseline and discharge/day 10, whereas post-discharge body weight change was defined as the difference between discharge/day 10 and day 30. Spearman rank correlations of weight change, urine output (UOP), and dyspnea relief as assessed by a 7-point Likert scale are described. Logistic and Cox proportional hazards regression was used to evaluate the relationship between weight change and outcomes. Study participants with complete body weight data (n = 4,172) had a mean age of 65 ± 14 years, and 66% were male. Ischemic heart disease was reported in 60% of patients and the average ejection fraction was 30 ± 13%. The median change in body weight was -1.0 kg (interquartile range: -2.1 to 0.0 kg) at 24 h and -2.3 kg (interquartile range: -5.0 to -0.7 kg) by discharge/day 10.

    To investigate the incidence rates of candidemia in hospitalized patients and to identify differences in risk factors of patients with Candida albicans and non-C. albicans and with Candida guilliermondii and non-C. guilliermondii candidemia. Non-immunosuppressed, non-neutropenic inpatients with candidemia diagnosed after admission were included in this retrospective observational study at a tertiary academic hospital in China. During the study period (January 2009 to December 2011), 238 eligible patients had candidemia episodes with an incidence rate 5.4%. Of these patients, 29.8% had candidemia due to C. albicans, 27.7% due to C. parapsilosis, and 16.4% due to C. guilliermondii. Diabetes was a significant risk factor for patients with candidemia due to C. albicans (35.2%, 25/71) compared to candidemia due to non-C. albicans spp (13.2%, 22/167) (odds ratio (OR) 0.2792, 95% confidence interval (CI) 0.144-0.5412; p candidemia due to non-C. guilliermondii spp, preterm birth with low birth weight (OR 0.0887, 95% CI 0.0398-0.1977; p candidemia due to C. guilliermondii. Furthermore, compared to patients with candidemia due to C. albicans, patients with candidemia due to C. guilliermondii had markedly higher rates of central venous catheterization (85.9%, 61/71 vs. C. guilliermondii: 100%, 39/39; p = 0.013) and intravenous nutrition (89.7%, 35/39 vs. C. albicans: 42.2%, 30/71; p Candidemia due to C. albicans ranks first in incidence, and candidemia due to C. guilliermondii occurs in a significant proportion of our hospitalized patients.

    Full Text Available The National Reporting and Learning System (NRLS collects reports about patient safety incidents in England. Government regulators use NRLS data to assess the safety of hospitals. This study aims to examine whether annual hospital incident reporting rates can be used as a surrogate indicator of individual hospital safety. Secondly assesses which hospital characteristics are correlated with high incident reporting rates and whether a high reporting hospital is safer than those lower reporting hospitals. Finally, it assesses which health-care professionals report more incidents of patient harm, which report more near miss incidents and what hospital factors encourage reporting. These findings may suggest methods for increasing the utility of reporting systems.This study used a mix methods approach for assessing NRLS data. The data were investigated using Pareto analysis and regression models to establish which patients are most vulnerable to reported harm. Hospital factors were correlated with institutional reporting rates over one year to examine what factors influenced reporting. Staff survey findings regarding hospital safety culture were correlated with reported rates of incidents causing harm; no harm and death to understand what barriers influence error disclosure.5,879,954 incident reports were collected from acute hospitals over the decade. 70.3% of incidents produced no harm to the patient and 0.9% were judged by the reporter to have caused severe harm or death.

    Studies have raised concern about the safety of generic compared with branded drugs. Febrile neutropenia (FN) resulting in hospital admission was compared between the branded docetaxel (Taxotere®, Sanofi) and 2 generic formulations (docetaxel Ebewe and docetaxel Hospira) in patients with breast cancer. This was a retrospective study that included patients with breast cancer who received docetaxel between January 2012 and December 2014. Patients who had an admission diagnosis of FN and had received docetaxel within 14 days prior to admission were evaluated. The docetaxel brand and dose, patient characteristics, hospital length of stay, admission to the intensive care unit (ICU), and mortality were recorded. During the study period, 2904 cycles of docetaxel were given for 876 patients (1519 cycles of docetaxel Sanofi, 811 cycles of docetaxel Hospira, and 574 cycles of docetaxel Ebewe). Among the cycles given, 130 cycles were associated with FN that required hospital admission. The overall incidence of FN resulting in hospital admission was significantly higher in patients who had received docetaxel Hospira, compared with patients who had received docetaxel Sanofi (47[5.8%] cycles vs 53 [3.5%] cycles, P = .009), but there was no significant difference between docetaxel Ebewe and docetaxel Sanofi (30[5.2%] cycles vs 53 [3.5%] cycles, P = .069). All cases of FN resolved except for 1 patient who died in the ICU after receiving docetaxel Ebewe. There was a significant difference in the incidence of FN between docetaxel Sanofi and docetaxel Hospira, but all cases in both groups resolved completely. © 2016, The American College of Clinical Pharmacology.

    Weight monitoring is an important element of HF self-care, yet the most clinically meaningful way to evaluate weight monitoring adherence is uncertain. We conducted this study to evaluate the association of (1) self-reported recall and (2) daily diary-recorded weight monitoring adherence with heart failure-related (HF-related) hospitalization. We conducted a prospective cohort study among 216 patients within a randomized trial of HF self-care training. All patients had an initial self-care training session followed by 15 calls (median) to reinforce educational material; patients were also given digital scales, instructed to weigh daily, record weights in a diary, and mail diaries back monthly. Weight monitoring adherence was assessed with a self-reported recall question administered at 12 months and dichotomized into at least daily versus less frequent weighing. Diary-recorded weight monitoring was evaluated over 12 months and dichotomized into ≥80% and review. Over 12 months in 216 patients, we identified 50 HF-related hospitalizations. Patients self-reporting daily or more frequent weight monitoring had an incidence rate ratio of 1.34 (95% CI 0.24-7.32) for HF-related hospitalizations compared to those reporting less frequent weight monitoring. Patients who completed ≥80% of weight diaries had an IRR of 0.37 (95% CI 0.18-0.75) for HF-related hospitalizations compared to patients who completed <80% of weight diaries. Self-reported recall of weight monitoring adherence was not associated with fewer HF hospitalizations. In contrast, diary-recorded adherence ≥80% of days was associated with fewer HF-related hospitalizations. Incorporating diary-based measures of weight monitoring adherence into HF self-care training programs may help to identify patients at risk for HF-related hospitalizations.

    Full Text Available Abstract Background Surgical site infections (SSI are one of the most common healthcare associated infections in the low-middle income countries. Data on incidence and risk factors for SSI following surgeries in general and Obstetric and Gynecological surgeries in particular are scare. This study set out to identify risk factors for SSI in patients undergoing Obstetric and Gynecological surgeries in an Indian rural hospital. Methods Patients who underwent a surgical procedure between September 2010 to February 2013 in the 60-bedded ward of Obstetric and Gynecology department were included. Surveillance for SSI was based on the Centre for Disease Control (CDC definition and methodology. Incidence and risk factors for SSI, including those for specific procedure, were calculated from data collected on daily ward rounds. Results A total of 1173 patients underwent a surgical procedure during the study period. The incidence of SSI in the cohort was 7.84% (95% CI 6.30–9.38. Majority of SSI were superficial. Obstetric surgeries had a lower SSI incidence compared to gynecological surgeries (1.2% versus 10.3% respectively. The risk factors for SSI identified in the multivariate logistic regression model were age (OR 1.03, vaginal examination (OR 1.31; presence of vaginal discharge (OR 4.04; medical disease (OR 5.76; American Society of Anesthesia score greater than 3 (OR 12.8; concurrent surgical procedure (OR 3.26; each increase in hour of surgery, after the first hour, doubled the risk of SSI; inappropriate antibiotic prophylaxis increased the risk of SSI by nearly 5 times. Each day increase in stay in the hospital after the surgery increased the risk of contacting an SSI by 5%. Conclusions Incidence and risk factors from prospective SSI surveillance can be reported simultaneously for the Obstetric and Gynecological surgeries and can be part of routine practice in resource-constrained settings. The incidence of SSI was lower for Obstetric surgeries

    To document the organisational response of Furness General Hospital to the large outbreak of legionnaire's disease in April 2002 and assess the contribution made by the hospital's major incident plan. Qualitative analysis of interview transcripts and written comments from some staff involved in the management of the incident. Documentary analysis of major incident plan and other written materials. The incident posed considerable managerial and clinical problems and this paper describes how they were overcome. In particular, strategies for dealing with supply (of staff, beds, and resources) and managing demand (by liaising with primary care and the public) seem to have been successful. Many functions necessary for managing the incident were poorly dealt with in the plan, especially procedures for handling the news media and liaison with agencies outside the hospital. Lack of explicit guidance appeared not to hinder the organisational response. There may have been an unspoken high level decision to allow staff to draw on their skills and experience in improvising a response to the initial challenge and learning adaptively as the incident unfolded. There was also evidence that staff disregarded existing job and role boundaries and focused instead on tasks, working flexibly to ensure that these tasks were completed. Protracted major incidents pose particular management challenges and may benefit from an approach different from that set out in typical major incident plans. Staff must be able to act flexibly and responsively. Some form of checklist or toolkit may be preferable to a detailed plan for some types of incident.

    Tracheostomies are increasingly common in hospital wards due to the rising use of percutaneous and surgical tracheostomies in critical care and bed pressures in these units. Hospital wards may lack appropriate infrastructure to care for this vulnerable group and significant patient harm may result. To identify and analyse tracheostomy related incident reports from hospital wards between 1 October 2005 and 30 September 2007, and to make recommendations to improve patient safety based on the recurrent themes identified. The study was performed between August 2008 and August 2009. 968 tracheostomy related critical incidents reported to the National Patient Safety Agency over the 2 year period, identified by key letter searches, were analysed. Incidents were categorised to identify common themes, and root cause analysis attempted where possible. In the 453 incidents where patients were directly affected, 338 (75%) were associated with some identifiable patient harm, of which 83 (18%) were associated with more than temporary harm. In 29 incidents (6%) some intervention was required to maintain life, and in 15 cases the incident may have contributed to the patient's death. Equipment was involved in 176 incidents and 276 incidents involved tracheostomies becoming blocked or displaced. By identifying and analysing themes in incident reports associated with tracheostomies, recommendations can be made to improve safety for this group of patients. These recommendations include improvements in infrastructure, competency and training, equipment provision, and in communication.

    The experiments at the Large Hadron Collider will have to deal with unprecedented radiation levels. The design of the CMS forward calorimetry detector (HF) is now finalized. The present design of CMS calls for the HF calorimeter to be based on quartz fiber technology. It consists of two modules, located symmetrically at about 11 meters from either side of interaction point. They cover the pseudorapidity range 3-5. The length along the beam is 1.65m or 10 nuclear interaction lenghts. Each calorimeter consists of a large steel block that serves as the absorber. Embedded quartz fibers in the steel absorber run parallel to the beam and constitute the active component of the detector. In order to optimize energy resolution for E and ET flows and forward jets, the calorimeter is effectively segmented longitudinally by using two different fiber lengths. The present status will be discussed.

    Postoperative hospital-acquired pneumonia (HAP) is recognized as a major risk associated with surgery. Although upper abdominal surgery is known to have the highest incidence of postoperative HAP, little is known about the risk factors that contribute to HAP after gastric cancer surgery. The aim of this study was to determine the incidence and risk factors for HAP after elective surgery for gastric cancer. We conducted prospective surveillance of all elective gastric resections by surgeons in ten affiliated hospitals, including ours, from May 2001 to May 2005. The outcome of interest was postoperative HAP. Univariate and multivariate analyses were performed to determine the predictive significance of variables in gastric cancer surgery. A total of 529 patients undergoing elective operations for gastric cancer were admitted to the program. Postoperative HAP was identified in 20 patients (3.6%). Univariate and multivariate analyses showed that male gender and intra- and/or postoperative blood transfusion were independently predictive of postoperative HAP. Male gender and intra- and/or postoperative blood transfusion were independent risk factors for the development of HAP after elective resection of gastric cancer. Surgeons should keep these risk factors in mind when managing postoperative patients.

  19. Survivable HF communications

    Science.gov (United States)

    Randerson, John T.

    Robust HF uses a noncoherent FSK (frequency-shift-keyed) signal. It uses fast pseudorandom frequency hopping and a rugged modulation format which makes it impervious to multipath, atmospheric, and man-made noise. It is optimized as an antijam system. The robust-HF operating frequency range is 2-30 MHz. The pseudorandom frequency hopping uses variable bandwidth and adapts to the best frequencies between the lowest usable frequency and the maximum usable frequency. The system operates skywave (long distance) or ground wave (up to 100 km, or even more over water). Buried hard antennas have been tested and show almost no degradation in system performance. Robust HF uses powerful error coding with variable code rates and code combining, which automatically adapt according to link conditions. The result is exceptional processing gain. A powerful cyclic redundancy check (CRC) is included to prevent delivery of corrupt data. System bit rates run as high as 600 b/s, with average throughput of about 75 b/s, depending on the code rate.

    Full Text Available CONTEXT: Although the benefits of antenatal corticosteroids have been widely demonstrated in other countries, there are few studies among Brazilian newborn infants. OBJECTIVE: To evaluate the effectiveness of antenatal corticosteroids on the incidence of respiratory distress syndrome and intra-hospital mortality among neonates with a gestational age of less than 34 weeks. TYPE OF STUDY: Cross-sectional. SETTING: A tertiary-care hospital. PARTICIPANTS: Neonates exposed to any dose of antenatal corticosteroids for fetal maturation up to 7 days before delivery, and newborns paired by sex, birth weight, gestational age and time of birth that were not exposed to antenatal corticosteroids. The sample obtained consisted of 205 exposed newborns, 205 non-exposed and 39 newborns exposed to antenatal corticosteroids for whom it was not possible to find an unexposed pair. PROCEDURES: Analysis of maternal and newborn records. MAIN MEASUREMENTS: The primary clinical outcomes for the two groups were compared: the incidence of respiratory distress syndrome and intra-hospital mortality; as well as secondary outcomes related to neonatal morbidity. RESULTS: Antenatal corticosteroids reduced the occurrence of respiratory distress syndrome (OR: 0.33; 95% CI: 0.21-0.51 and the protective effect persisted when adjusted for weight, gestational age and the presence of asphyxia (adjusted OR: 0.27; 95% CI: 0.17-0.43. The protective effect could also be detected through the reduction in the need for and number of doses of exogenous surfactant utilized and the number of days of mechanical ventilation needed for the newborns exposed to antenatal corticosteroids. Their use also reduced the occurrence of intra-hospital deaths (OR: 0.51: 95% CI: 0.38-0.82. However, when adjusted for weight, gestational age, presence of prenatal asphyxia, respiratory distress syndrome, necrotizing enterocolitis and use of mechanical ventilation, the antenatal corticosteroids did not maintain the

    To describe the reported incidence of out of hospital cardiac arrest (OHCA) and the characteristics and outcome after OHCA in relation to population density in Sweden. All patients participating in the Swedish Cardiac Arrest Register between 2008 and 2009 in (a) 20 of 21 regions (n=6457) and in (b) 165 of 292 municipalities (n=3522) in Sweden, took part in the survey. The regional population density varied between 3 and 310 inhabitants per km(2) in 2009. In 2008-2009, the number of reported cardiac arrests varied between 13 and 52 per 100,000 inhabitants and year. Survival to 1 month varied between 2% and 14% during the same period in different regions. With regard to population density, based on municipalities, bystander CPR (p=0.04) as well as cardiac etiology (p=0.002) were more frequent in less populated areas. Ambulance response time was longer in less populated areas (ppopulation density and survival to 1 month after OHCA or incidence (adjusted for age and gender) of OHCA. There was no significant association between population density and survival to 1 month after OHCA or incidence (adjusted for age and gender) of OHCA.

    The objective of the study was to determine the incidence of transaminase elevation during dengue, and its predictive factors. In 2013, a longitudinal study was performed using data from all cases of dengue seen in Cayenne Hospital. Cox proportional modeling was used. Signs of major transaminase elevation were defined as an increase in aspartate amino transferase (AST) or alanine amino transferase (ALT) concentration over 10 times the normal value (10N). There were 1574 patients and 13 249 person-days of follow-up. The incidence rate for signs of transaminase elevation (10N) was 0.55 per 100 person-days. Six patients had major transaminase elevation with AST>1000 units (0.43 per 1000 patient-days), and 73 patients (4.6%) developed transaminase elevation with AST >10N. The variables independently associated with major transaminase elevation were hyponatremia, low platelets, dehydration, hematocrit increase, food intolerance, positive nonstructural protein 1 (NS1), age over 15 years and the notion of paracetamol intake. Although very frequent, the incidence of major transaminase elevation was lower than reported elsewhere perhaps because of good access to care, or of the particular serotype causing this epidemic. The patients with transaminase elevation tended to be older, more severe and taking paracetamol. . © The Author 2016.

    All the cultures for mycobacteriae taken from 1967 to 1973 at the Hospital General del Centro Médico Nacional del Instituto Mexicano del Seguro Social were reviewed. From 802 positive cultures, 361 (44.2 per cent) were atypical mycobacteriae. 89 per cent of them were scotochromogen, 10.3 per cent of rapid growth, one non-chromogen, and none were photochromogen. These data are in contrast with those observed in other countries. Isolation sources varied also from other reports, in this series the most common isolation were from urine specimens, sputum, feces and bone marrow. A possible explanation for that in this hospital there are very few pulmonary patients. The percentage of atypical mycobacteriae was greatest in the last two years. In bacterioscopic examination atypical micobacteriae were detected less frequently than M. tuberculosis.

    Full Text Available We studied 19 cases of proven/probable mucormycosis diagnosed from 2007 to 2015 in our hospital and assessed the microbiological characteristics of the isolates. We recorded the incidence of mucormycosis and clinical and microbiological data of infected patients. Isolates were identified to molecular level and tested for their antifungal susceptibility to azoles, amphotericin B, and liposomal amphotericin B according to the CLSI M-38 A2 procedure. The incidence of mucormycosis in cases/100,000 hospital admissions during 2007-2015 increased significantly with respect to that reported in 1988-2006 (3.3 vs. 1.2; P<0.05. Patients mainly had hematological malignancies (52.6% and/or trauma/surgical wounds (52.6% and had received antifungal agents before the diagnosis of mucormycosis in 68% of cases. Diagnosis was by isolation (n = 17/19 and/or direct staining (n = 17/18 of Mucorales fungi in clinical samples. Identification was by panfungal PCR in patients with negative results in culture and in direct staining. The microorganisms identified were Lichtheimia spp. (42%, Rhizopus spp. (21%, Cunninghamella bertholletiae (16%, and others (21%. Liposomal amphotericin B was always more active than the other drugs against all the microorganisms except C. bertholletiae. All patients received antifungal treatment with 1 or more antifungal agents, mainly liposomal amphotericin B (17/19. Mortality was 47.4%, although this was significantly lower in the 11 patients in whom debridement was performed (18% vs. 87.5% (P = 0.015. The incidence of mucormycosis has risen in recent years. The proportion of cases with soft tissue involvement was high, and Lichtheimia was the most frequently involved species. The highest antifungal activity was observed with liposomal amphotericin B.

    Nurses in acute medical units are uniquely positioned to support goals of care communication. Further understanding of nurse and physician perceptions about hospital nurses' actual and possible roles was required to improve goals of care communication. To critically examine nurse and physician perceptions of the nurse's role in communication with seriously ill patients and their families. We focus on the qualitative component of a mixed method study. We employed an interpretive descriptive approach informed by Flanagan's critical incident technique. Participants were recruited from the acute medical units at three tertiary care hospitals in three Canadian provinces. Thirty participants provided interviews (10 from each site): 12 nurses, 9 staff physicians and 9 medical resident physicians. Participants' described "critical incidents" they considered as "excellent" or "poor" or "usual" practice. Interviews, were audiotaped and transcribed. Team-based analysis used constant comparison and triangulation to identify healthcare team members' roles in goals of care communication. We identified two major themes from 120 critical incidents: 1) the ambiguous nature of the nurse's role in formal, physician-led, decision-making communication, and 2) embedded in care serious illness communication. Physicians understood nurses' supportive role in relation to their own communication practices that culminated in decisions about care; nurses' reported their roles were determined by unit routines, physician practices and preferences, and their self-confidence in supporting decision-making. Nurses described their unique role in facilitating informal and spontaneous communication with patients and families that was critical background work to physician-led goals of care communication. Nurses and physicians had different understandings, practices and beliefs about goals of care communication The value of nurses embedded in care work is key to supporting the interprofessional team

    Fall rates from 3.2 to 17.1 falls per 1,000 hospital days in geriatric psychiatry facilities have been reported to date. Up to 5% of the falls result in severe injuries, but data concerning medical consequences are scare. This brief report presents a retrospective analysis of one year fall protocols from a geriatric psychiatry department focusing on consequences of falls. Fall-induced injuries were rated in four categories: no injuries, mild injuries (contusions, hematomas, abrasions), moderate injuries (lacerations, dislocations), and severe injuries (fractures, cerebral hemorrhages). In total, 510 falls were registered during the study period, indicating a fall rate of 17.7 falls per 1,000 hospital days. Overall, 375 falls (73.5%) resulted in no injuries, 67 (13.1%) resulted in mild injuries, 59 (11.6%) resulted in moderate injuries, and only 9 (1.8%) falls led to severe injuries (fractures and cerebral hemorrhages). These results indicate a quite high fall rate in our sample of hospitalized geriatric psychiatry patients with only a relatively small number of severe injuries resulting from the falls. These results raise the question about the use of physical restraints and the use of bedrails in geriatric patients to prevent falls as the medical implications of falls may be less problematic than previously thought.

    To analyze the effectiveness of a multicomponent intervention integrated into daily practice for the prevention of in-hospital delirium in elderly patients. Controlled study comparing an intervention in a geriatric unit (GI) with usual care in two internal medicine services (UC). University hospital in Madrid, Spain. Five hundred forty-two consecutive patients (170 GI, 372 UC), aged 70 and older, with any of the risk criteria for delirium (cognitive impairment, visual impairment, acute disease severity, dehydration). Educational measures and specific actions in seven risk areas (orientation, sensory impairment, sleep, mobilization, hydration, nutrition, drug use). Daily monitoring of adherence. Baseline characteristics, risk factors for delirium, and quality care indicators were analyzed. The primary endpoint was incidence of delirium assessed daily. The secondary endpoint was functional decline, defined as loss of independence in any of the activities of daily living. The intervention effect was evaluated using logistic regression analysis. Delirium affected 11.7% of the GI group and 18.5% of the UC group (P=.04). After adjustment for confounders, the intervention was associated with lower incidence of delirium (odds ratio=0.4, 95% confidence interval=0.24-0.77; P=.005). In the patients who experienced delirium, severity, length, and recurrence of episodes were similar in both groups. Adherence to the intervention protocols was 75.7%. The intervention reduced the rate of functional decline (45.5% in GI vs 56.3% in UC, P=.03) and improved other quality indicators (e.g., mobilization and physical restraints reduction). A multicomponent, nonpharmacological intervention integrated into routine practice reduces delirium during hospitalization in older patients, improves quality of care, and can be implemented without additional resources in a public healthcare system.

    The objective of this study was to evaluate the association of chocolate consumption and heart failure (HF) in a large population of Swedish men. We conducted a prospective cohort study of 31,917 men 45-79 years old with no history of myocardial infarction, diabetes, or HF at baseline who were participants in the population-based Cohort of Swedish Men study. Chocolate consumption was assessed through a self-administrated food frequency questionnaire. Participants were followed for HF hospitalization or mortality from January 1, 1998, to December 31, 2011, using record linkage to the Swedish inpatient and cause-of-death registries. During 14 years of follow-up, 2,157 men were hospitalized (n=1,901) or died from incident HF (n=256). Compared with subjects who reported no chocolate intake, the multivariable-adjusted rate ratio of HF was 0.88 (95% CI 0.78-0.99) for those consuming 1-3 servings per month, 0.83 (95% CI 0.72-0.94) for those consuming 1-2 servings per week, 0.82 (95% CI 0.68-0.99) for those consuming 3-6 servings per week, and 1.10 (95% CI 0.84-1.45) for those consuming ≥1 serving per day (P for quadratic trend=.001). In this large prospective cohort study, there was a J-shaped relationship between chocolate consumption and HF incidence. Moderate chocolate consumption was associated with a lower rate of HF hospitalization or death, but the protective association was not observed among individuals consuming ≥1 serving per day.

    Patients are increasingly being thought of as central to patient safety. A small but growing body of work suggests that patients may have a role in reporting patient safety problems within a hospital setting. This review considers this disparate body of work, aiming to establish a collective view on hospital-based patient reporting. This review asks: (a) What can patients report? (b) In what settings can they report? (c) At what times have patients been asked to report? (d) How have patients been asked to report? 5 databases (MEDLINE, EMBASE, CINAHL, (Kings Fund) HMIC and PsycINFO) were searched for published literature on patient reporting of patient safety 'problems' (a number of search terms were utilised) within a hospital setting. In addition, reference lists of all included papers were checked for relevant literature. 13 papers were included within this review. All included papers were quality assessed using a framework for comparing both qualitative and quantitative designs, and reviewed in line with the study objectives. Patients are clearly in a position to report on patient safety, but included papers varied considerably in focus, design and analysis, with all papers lacking a theoretical underpinning. In all papers, reports were actively solicited from patients, with no evidence currently supporting spontaneous reporting. The impact of timing upon accuracy of information has yet to be established, and many vulnerable patients are not currently being included in patient reporting studies, potentially introducing bias and underestimating the scale of patient reporting. The future of patient reporting may well be as part of an 'error detection jigsaw' used alongside other methods as part of a quality improvement toolkit.

    Full Text Available Background: Candida species are important hospital-acquired pathogens in infants admitted to the neonatal intensive care unit (NICU. This study was performed in the NICU of Saudi Arabian Hospital, Riyadh region, KSA to analyze patterns of neonatal Candida colonization as well as to determine the potential risk factors.Methods: Weekly surveillance fungal cultures of anal area, oral cavity, umbilicus and ear canal of neonates were performed from birth until their discharge from the hospital. Colonization was analyzed for timing, site, species, birth weight and gestational age. Potential environmental reservoirs and hands of health care workers (HCWs were also cultured monthly for fungi. Antifungal susceptibility of the identified isolates was also determined.Results: One hundred subjects have been recruited in this study. The overall colonization rate was 51%. Early colonization was found in 27 (27% neonates whereas 24 (24% neonates were lately colonized during their stay in NICU. Colonization was more in preterm neonates than in full and post term. Perianal area and oral cavity were the most frequent colonized sites. C. albicans was the main spp. (58.8% isolated from the neonates followed by C. tropicalis (17.6%, C. glabrata (15.6%, and C. krusei (2%. Of the 51 isolated Candida spp., 68.6% were sensitive to fluconazole, 80% to itraconazole and 64.7% to ketoconazole, while only 33% were sensitive to amphotericin B.Conclusion: Candida has emerged as a common cause of infections in infants admitted to NICU, and C. albicans is the most commonly isolated candidal species. Neonatal infections caused by non- albicans species occur at a later age during their stay in NICU.

    BACKGROUND: Surveillance of Clostridium difficile infection (CDI) is an essential component of a CDI preventative programme. AIMS: The aim of this study was to evaluate two methods of CDI surveillance. METHODS: Prevalence of CDI, antibiotic use and associated co-morbidity was assessed weekly on two wards over 6 weeks. In addition, CDI incidence surveillance was performed on all new CDI cases over a 13-week period. Cases were assessed for CDI risk factors, disease severity, response to treatment and outcome at 6 months. RESULTS: Clostridium difficile infection prevalence was 3.5% (range 2.9-6.1%) on the medical ward and 1.1% (range 0-3.5%) on the surgical ward. Patients on the medical ward were older and more likely to be colonised with MRSA; however, recent antibiotic use was more prevalent among surgical patients. Sixty-one new CDI cases were audited. Patients were elderly (mean age 71 years) with significant co-morbidity (median age adjusted Charlson co-morbidity score 5). CDI ribotypes included 027 (29 cases) 078 (5) and 106 (4). Eight patients developed severe CDI, seven due to 027. Antibiotic use was common with 56% receiving three or more antibiotics in the preceding 8 weeks. Twenty-four patients had died at 6 months, five due to CDI. CONCLUSION: Clostridium difficile infection prevalence gives a broad overview of CDI and points to areas that require more detailed surveillance and requires little time. However, patient-based CDI incidence surveillance provides a more useful analysis of CDI risk factors, disease and outcome for planning preventative programmes and focusing antibiotic stewardship efforts.

    Nosocomial infections (NIs) are one of the most important health issues, particularly in developing countries, because these infections cause high mortality and morbidity, and economic and human resource loss as a consequence. To date, most surveillance studies have been conducted in developed countries, and only a few have been performed in Iran. All of the few Iranian studies have been performed using paper-based collection forms, and none was conducted with the aid of an electronic patient data retrieving and collecting tool. The aim of this study is to determine the incidence of NIs in a big university hospital of Shiraz, with the help of specifically programmed surveillance software merging electronically the available patient data and the infection results input manually. The study was conducted prospectively through 6 months from 21(st) March up to 22(nd) September 2006, in a 374-bedded educational hospital. All patients admitted during this period were included in the study and examined everyday for detecting four types of NIs: surgical site infection (SSI), urinary tract infection (UTI), pneumonia (PNEU), and blood stream infection (BSI). Centres for Disease Control and Prevention National Nosocomial Infection Surveillance system criteria were applied. 4013 patients were admitted in the hospital. The overall infection rate was 4.14, and UTI, SSI, BSI, and PNEU rates were 1.82, 1.22, 0.5, and 0.5, respectively, per 1000 patient days of admission. The results of this study showed that the frequency of NI in the investigated hospital was not higher than in many other reported surveillance results from other countries. This, however, might be a bias as the administration of antibiotics was very high in this study and the quality of microbiological investigation might have influenced significantly, resulting in more false-negative results than expected. Overall, the use of the Iranian National Nosocomial Infection Surveillance System Software proved to be

    Adverse drug reactions (ADRs) are a reporting category in the National Patient Safety Agency (NPSA) incident reporting system, though the Medicines and Healthcare Products Regulatory Agency (MHRA) pharmacovigilance system is the more established method for collecting ADR data. The majority of ADRs were shown to be of moderate risk to the patient, though some have a severe or catastrophic impact. Classification and reporting of ADRs according to NPSA guidance is possible but offers limited additional value to efforts to improve patient safety over and above the Yellow Card Scheme. In the UK, the National Patient Safety Agency (NPSA) includes adverse drug reactions as a reporting category, while the MHRA Yellow Card Scheme also collects data regarding adverse drug reactions (ADRs). In this study, we aimed to assess ADRs using NPSA criteria and discuss the resulting implications. ADRs identified in a 6-month prospective study of 3695 inpatient episodes were assessed according to their impact on the patient and on the organization, using tools developed by the NPSA. Seven hundred and thirty-three (100%) ADRs were assessed. In terms of impact on the patient, 537 (73.3%) were categorized as 'low' (minor treatment), 181 (24.7%) as 'moderate' (moderate increase in treatment, no permanent harm), 14 (1.91%) as 'severe' (permanent harm) and 1 (0.14%) was categorized as 'catastrophic' (direct cause of death). In terms of impact on the organization, none was categorized as 'no harm/no risk', 508 (69.3%) as 'insignificant', 188 (25.6%) as 'minor', 25 (3.4%) as 'moderate', 12 (1.6%) as 'major' and none was classed as 'catastrophic'. Less than 2% of ADRs would be eligible for detailed analysis according to the NPSA guidance. The ADRs that cause incidents of greater significance relate to bleeding, renal impairment and Clostridium difficile infection. Classification of ADRs according to NPSA guidance offers limited additional value over and above that offered by the Yellow Card

    Full Text Available Purpose: Increasing reports on New Delhi metallo-β-lactamase-1 (NDM-1 producing Escherichia coli constitute a serious threat to global health since it is found to be highly resistant to most of the currently available antibiotics including carbapenems. This study has been performed to find out the incidence blaNDM-1 in E. coli isolates recovered from the various clinical samples at a tertiary care referral hospital in Northeast India. Materials and Methods: A total of 270 non-duplicated E. coli isolates were recovered from the various clinical samples at a tertiary care referral hospital in Northeast India. All isolates with reduced susceptibility to meropenem or ertapenem (diameter of zones of inhibition, ≤21 mm were further phenotypically confirmed for carbapenemase production by modified Hodge test. All screened isolates were also subjected to the polymerase chain reaction detection of blaNDM-1 gene and additional bla genes coding for transmission electron microscopy, SHV, CTX-M, and AmpC. Results: Out of 270 E. coli isolates, 14 were screened for carbapenemase production on the basis of their reduced susceptibility to meropenem or ertapenem. All screened isolates were found to be positive for blaNDM-1 . Each of the blaNDM-1 possessing isolate was also positive for two or more additional bla genes, such as blaTEM , blaCTX-M and blaAmpC . Phylogenetic analysis showed very less variation in blaNDM-1 gene with respect to blaNDM-1 possessing E. coli isolates from other parts of India and abroad. Conclusions: Our findings highlight the incidence of blaNDM-1 in E. coli isolates with a reduced susceptibility to meropenem or ertapenem.

    The HF laser is an attractive candidate driver for a large-system ICF scientific demonstration facility, for an ICF experimental power reactor and for a commercial laser--fusion power reactor. Previous accomplishments of the program have included demonstrations of high efficiency and high energy capability, efficient energy extraction from HF amplifiers, good beam quality and focusability, and short-pulse generation and amplification. In the reporting period, beam quality has been determined to be near-diffraction limited for a short pulsewidth (6 ns to 25 ns) oscillator-amplifier chain, suppression of amplified spontaneous emission has been demonstrated on an individual spectral line, high-pressure characteristics have been determined for the Phoenix I amplifier, and detailed comparisions between the kinetic code and experiments have been made. Details of two major upcoming experiments are also included. The first is energy extraction and beam quality measurements on the Phoenix I amplifier operating under saturated output power conditions. The second experiment, using a newly designed amplifier (Phoenix II), is designed to demonstrate the concept of angular-multiplexing: a pulse width-compression scheme

    Full Text Available Abstract Background Medication errors have been reported to be a leading cause of death in hospitalized patients. In this study we focused on identifying and quantifying errors in the handwritten drug ordering and dispensing documentation processes which could possibly lead to adverse drug events. Methods We studied 1,934 ordered agents (165 consecutive patients retrospectively for medication documentation errors. Errors were categorized into: Prescribing errors, transcription errors and administration documentation errors on the nurses' medication lists. The legibility of prescriptions was analyzed to explore its possible influence on the error rate in the documentation process. Results Documentation errors occurred in 65 of 1,934 prescribed agents (3.5%. The incidence of patient charts showing at least one error was 43%. Prescribing errors were found 39 times (37%, transcription errors 56 times (53%, and administration documentation errors 10 times (10%. The handwriting readability was rated as good in 2%, moderate in 42%, bad in 52%, and unreadable in 4%. Conclusions This study revealed a high incidence of documentation errors in the traditional handwritten prescription process. Most errors occurred when prescriptions were transcribed into the patients' chart. The readability of the handwritten prescriptions was generally bad. Replacing the traditional handwritten documentation process with information technology could potentially improve the safety in the medication process.

    Kampo medicine is traditional Japanese medicine, which originated in ancient traditional Chinese medicine, but was introduced and developed uniquely in Japan. Today, Kampo medicines are integrated into the Japanese national health care system. Incident reporting systems are currently being widely used to collect information about patient safety incidents that occur in hospitals. However, no investigations have been conducted regarding patient safety incident reports related to Kampo medicines. The aim of this study was to survey and analyse incident reports related to Kampo medicines in a Japanese university hospital to improve future patient safety. We selected incident reports related to Kampo medicines filed in Toyama University Hospital from May 2007 to April 2017, and investigated them in terms of medication errors and adverse drug events. Out of 21,324 total incident reports filed in the 10-year survey period, we discovered 108 Kampo medicine-related incident reports. However, five cases were redundantly reported; thus, the number of actual incidents was 103. Of those, 99 incidents were classified as medication errors (77 administration errors, 15 dispensing errors, and 7 prescribing errors), and four were adverse drug events, namely Kampo medicine-induced interstitial pneumonia. The Kampo medicine (crude drug) that was thought to induce interstitial pneumonia in all four cases was Scutellariae Radix, which is consistent with past reports. According to the incident severity classification system recommended by the National University Hospital Council of Japan, of the 99 medication errors, 10 incidents were classified as level 0 (an error occurred, but the patient was not affected) and 89 incidents were level 1 (an error occurred that affected the patient, but did not cause harm). Of the four adverse drug events, two incidents were classified as level 2 (patient was transiently harmed, but required no treatment), and two incidents were level 3b (patient was

    to determine the incidence, frequency of risk factors, diagnostic aspects (clinics, biochemical, and images) and therapeutic aspects of the choledocholithiasis. Descriptive and prospective analysis of 51 patients who signed informed consent for study of choledocholithiasis by ERCP (endoscopic retrograde cholangiopancreatography). Of the 51 patients, 36 (70.6%) confirmed choledocholithiasis by ERCP. Its incidence was 10.4%. The mean age was 63.75 years, BMI 25.59 kg/m2 and 55.6% were women. Abdominal pain was present in 94.4% of patients. Total bilirubin in the group with choledocholithiasis was 5.8 mg / dl at baseline and 4.2 mg / dl in hospitalization. 11.1% debuted with pancreatitis and 30.6% with cholangitis. In 68.7% of patients with cholangitis was confirmed choledocholithiasis by ERCP. The specificity of ultrasound was 0.80 (95% CI 0.6- 1). The specificity of the nuclear magnetic resonance was 0.25 (95% CI 0.17-0.67). Of the 51 patients with ERCP, 4 (7.80%) do pancreatitis, 1(1.96%) cholangitis and 2 (3.92%) bleeding Choledocholithiasis occurs in older people, female and overweight with an incidence of 10.4%. Abdominal pain is the most common symptom. A total bilirubin more tan 4mg/dl occurs in patients with choledocholithiasis. The complications of choledocholithiasis (pancreatitis and cholangitis) were more frequent than reported in the literature. Both the specificity of cholangitis for choledocholithiasis, the specificity of ultrasound and the specificity of the nuclear magnetic resonance were lower than reported in the literature. ERCP complications were slightly higher than that reported in the literature.

    Full Text Available Background: Perinatal asphyxia is a common cause of infant morbidity and mortality and long-term neurological disabilities. Due to the high costs of admission, a large proportion of births and neonatal deaths occur in non-hospital settings. This study aimed to evaluate the incidence rate of perinatal asphyxia before and after the implementation of the health improvement program. Methods: This descriptive-analytical study was conducted on all the infants with moderate and severe asphyxia during April 2013-2015. Subjects were divided into two groups of A and B (born after and before the health improvement program, respectively. Maternal and neonatal data were recorded in checklists and compared between these  groups. Data analysis was performed in SPSS version 17. Results: In total, 111 asphyxiated neonates were classified into two groups of A and B, and incidence rate of asphyxia was estimated at 0.54% and 1.05%, respectively. Severe asphyxia was observed in 35.7% and 28.9% of the infants in groups A and B, respectively. Moreover, mean duration of mechanical ventilation was 25 and 79 hours in groups A and B, respectively. Conclusion: According to the results of this study, implementation of the health improvement program reduced the incidence of perinatal asphyxia. In addition, number of cesarean cases due to previous C-section was observed to decrease. Therefore, it could be concluded that high-quality resuscitation efforts and restricted rules in the health improvement program lower the risk of long-term complications in asphyxiated neonates. However, no significant difference was observed in the mortality rate of the asphyxiated newborns in this study.

    2014-10-01

    Full Text Available Introduction: Carcinoid tumors are neuroendocrine malignancies that originate in the neuroectodermal cells of the Amine, Peptide Uptake and Decarboxylation system dispersed in the gastrointestinal mucosa and representing about 80–88% of tumors of cecal appendix. These are tumors usually diagnosed at appendectomies, and it is estimated that from each 100 appendectomies yearly performed, at least one case is a neuroendocrine tumor. Objectives: To report the experience of an University Teaching Hospital in health and reference at the east side of São Paulo and great São Paulo in cases of these rare appendicular tumors, with emphasis on the importance of these descriptions, as probably are rare those surgeons in particular who will acquire extensive wisdom in these cases. Method: Retrospective analysis of 237 patients who underwent appendectomy from September 2010 to September 2012 in the Hospital Santa Marcelina-SP. We evaluated data on age, gender, initial clinical presentation and surgical findings of patients undergoing appendectomy with subsequent anatomic and immunopathological diagnosis of carcinoid tumor of cecal appendix. Results: The presence of a carcinoid tumor of the appendix was observed in 5 patients, which corresponds to 2.1% of all appendectomies performed. Regarding gender, 4 patients (80% were female and the average age was 34.2 years, with a range from 17 to 68 years. In all patients the initial hypothesis for surgery indication was acute appendicitis, with an intraoperative finding of necroperforated phase acute appendicitis in 3 patients (60%. Conclusion: The therapeutical conduct after the diagnosis of carcinoid tumors of the appendix must be based on the data provided by pathological and immunohistochemical studies, besides the judicious judgment of the attending physician.

    Full Text Available In the neonatal intensive care units, infection with uncommon organisms is an increasing problem. Due to advances in medical and surgical management, an increase in nosocomial fungal infection rate has been observed, with Candida species being the most common nosocomial fungal pathogen. MATERIALS AND METHODS A total of 462 clinically suspected cases of septicaemia from neonatal ICU in Kamla Raja Paediatrics Hospital, Gwalior were studied for one year from November 2014 to October 2015. Blood samples were aseptically collected in duplicate into Brain Heart Infusion broth and incubated at 37°C up to 05 days and further another 05 days. Subcultures were made on Blood agar and MacConkey agar on regular interval. Both bacteria and yeast were isolated. The yeasts were studied further for identification and susceptibility as per the standard procedures. RESULTS Out of 103 culture positive cases, bacteria were isolated from 69 cases (66.7 % and yeast from 34 cases (33.3 %. Among yeasts, C. tropicalis was isolated from 21 cases (61.76 %, C. albicans from 6 (17.6 %, C. glabrata from 3 (8.8 %, C. parapsilosis and C. kefyr were isolated from 2 cases (5.9 % each. CONCLUSION Neonatal candidaemia is associated with significant morbidity and mortality. C. tropicalis has been reported as the predominant species involved in the cases of fungaemia.

    A retrospective analysis of 2209 urine samples submitted for culture to the Microbiology Laboratory of the Tikur Anbessa Hospital (TAH), Addis Ababa, between January 1992 and December 1994 was made. Significant bacteriuria (colony count > 10(5) colony forming units/ml urine) was detected in 672 (30%). Pure culture was obtained in 510 (23%) of all samples and polymicrobial growth was detected in the remaining 162 (7%). Gram-negative bacteria comprised 95% of all isolates. The commonest organisms being Escherichia coli (39%) and Klebsiella species (26%). Among the gram-positives, Staphylococcus aureus (57%) was the most common pathogen isolated. Most of the organisms were resistant to multiple drugs. Ampicillin, carbenicillin, chloramphenicol, tetracycline and trimethoprim-sulphamethoxazole were effective in less than 30% of all cases. There was also a significant resistance to cephalothin, gentamicin and kanamycin. Only nalidixic acid and nitrofurantoin were effective for most of the organisms. Compared to previous studies, there is an indication of reduced effectiveness of the commonly prescribed antibiotics. The rational use of drugs should be practiced in order to prevent the emergence of multi-drug resistant microorganisms.

    Full Text Available It is estimated that one third of the world's population is latently infected with tuberculosis (TB. The HIV epidemic fuels the TB epidemic by increasing the risk of reactivation of latent TB infection and by facilitating a more rapid progression of TB disease. Although the incidence of TB is constant or decreasing in many regions of the world, rates remain high in developing countries as a consequence of the HIV epidemic. This study was conducted as a collaboration of the Infectious Diseases department of Imam Khomeini Hospital with the Microbiology department of Tehran University of Medical Sciences. The hospital dataset of 94 patients admitted with TB during 2003-2005 was reviewed. We aimed to study factors correlating with positive blood culture including age, sex, immune deficiency status, HIV serology and SIRS (Systemic Inflammatory Response Syndrome status. In this study, we found that positive blood cultures are more frequent in patients less than 45 years old. Positive blood cultures were also more frequent in HIV infected patients and there was a significant correlation between blood culture and SIRS status. Therefore, we recommend that we obtain blood cultures from these high-risk groups in order to increase early detection of TB.

    In this first attempt to implement a standardized surveillance system of surgical site infections (SSI) in a Greek hospital, our objective was to identify areas for improvement by comparing main epidemiologic and microbiologic features of SSI with international data. The National Nosocomial Infections Surveillance (NNIS) system protocols were employed to prospectively collect data for patients in 8 surgical wards who underwent surgery during a 9-month period. SSI rates were benchmarked with international data using standardized infection ratios. Risk factors were evaluated by multivariate logistic regression. A total of 129 SSI was identified in 2420 operations (5.3%), of which 47.3% developed after discharge. SSI rates were higher for 2 of 20 operation categories compared with Spanish and Italian data and for 12 of 20 categories compared with NNIS data. Gram-positive microorganisms accounted for 52.1% of SSI isolates, and Enterococci were predominant. Alarming resistance patterns for Enterococcus faecium and Acinetobacter baumannii were recorded. Potentially modifiable risk factors for SSI included multiple procedures, extended duration of operation, and antibiotic prophylaxis. SSI was associated with prolongation of postoperative stay but not with mortality. Comparisons of surveillance data in our hospital with international benchmarks provided useful information for infection control interventions to reduce the incidence of SSI.

    Full Text Available This study reports the occurrence of antibiotic resistance and production of β-lactamases including extended spectrum beta-lactamases (ESβL in enteric bacteria isolated from hospital wastewater. Among sixty-nine isolates, tested for antibiotic sensitivity, 73.9% strains were resistant to ampicillin followed by nalidixic acid (72.5%, penicillin (63.8%, co-trimoxazole (55.1%, norfloxacin (53.6%, methicillin (52.7%, cefuroxime (39.1%, cefotaxime (23.2% and cefixime (20.3%. Resistance to streptomycin, chloramphenicol, nitrofurantoin, tetracycline, and doxycycline was recorded in less than 13% of the strains. The minimum inhibitory concentration (MIC showed a high level of resistance (800-1600 µg/mL to one or more antibiotics. Sixty three (91% isolates produced β-lactamases as determined by rapid iodometric test. Multiple antibiotic resistances were noted in both among ESβL and non-ESβL producers. The β-lactamases hydrolyzed multiple substrates including penicillin (78.8% isolates, ampicillin (62.3%, cefodroxil (52.2%, cefotoxime (21.7% and cefuroxime (18.8%. Fifteen isolates producing ESβLs were found multidrug resistant. Four ESβL producing isolates could transfer their R-plasmid to the recipient strain E. coli K-12 with conjugation frequency ranging from 7.0 x 10-3 to 8.8 x 10-4. The findings indicated that ESβL producing enteric bacteria are common in the waste water. Such isolates may disseminate the multiple antibiotic resistance traits among bacterial community through genetic exchange mechanisms and thus requires immediate attention.

    Optimal strategies for limiting the transmission of extended-spectrum β-lactamase-producing Escherichia coli and Klebsiella spp (ESBL-EK) in the hospital setting remain unclear. The objective of this study was to evaluate the impact of a urine culture screening strategy on the incidence of ESBL-EK. Prospective quasi-experimental study. Two intervention hospitals and one control hospital within a university health system from 2005 to 2009. All clinical urine cultures with E. coli or Klebsiella spp were screened for ESBL-EK. Patients determined to be colonized or infected with ESBL-EK were placed in a private room with contact precautions. The primary outcome of interest was nosocomial ESBL-EK incidence in nonurinary clinical cultures (cases occurring more than 48 hours after admission). Changes in monthly ESBL-EK incidence rates were evaluated with mixed-effects Poisson regression models, with adjustment for institution-level characteristics (eg, total admissions). The overall incidence of ESBL-EK increased from 1.42/10,000 patient-days to 2.16/10,000 patient-days during the study period. The incidence of community-acquired ESBL-EK increased nearly 3-fold, from 0.33/10,000 patient-days to 0.92/10,000 patient-days (P < .001). On multivariable analysis, the intervention was not significantly associated with a reduction in nosocomial ESBL-EK incidence (incidence rate ratio, 1.38 [95% confidence interval, 0.83-2.31]; P - .21). Universal screening of clinical urine cultures for ESBL-EK did not result in a reduction in nosocomial ESBL-EK incidence rates, most likely because of increases in importation of ESBL-EK cases from the community. Further studies are needed on elucidating optimal infection control interventions to limit spread of ESBL-producing organisms in the hospital setting.

    The Dietary Approaches to Stop Hypertension (DASH) diet effectively reduces blood pressure. In observational studies, the association between diets consistent with DASH and risk of coronary heart disease and stroke has been examined with varying results. We hypothesized that diets consistent with the DASH diet would be associated with a lower incidence of heart failure (HF). We conducted a prospective observational study in 36 019 participants in the Swedish Mammography Cohort who were aged 48 to 83 years and without baseline HF, diabetes mellitus, or myocardial infarction. Diet was measured using food-frequency questionnaires. We created a score to assess consistency with the DASH diet by ranking the intake of DASH diet components and 3 additional scores based on food and nutrient guidelines. Cox proportional hazards models were used to calculate rate ratios of HF-associated hospitalization or death, determined using the Swedish inpatient and cause-of-death registers between January 1, 1998, and December 31, 2004. During 7 years, 443 women developed HF. Women in the top quartile of the DASH diet score based on ranking DASH diet components had a 37% lower rate of HF after adjustment for age, physical activity, energy intake, education status, family history of myocardial infarction, cigarette smoking, postmenopausal hormone use, living alone, hypertension, high cholesterol concentration, body mass index (calculated as weight in kilograms divided by height in meters squared), and incident myocardial infarction. Rate ratios (95% confidence intervals) across quartiles were 1 [Reference], 0.85 (0.66-1.11), 0.69 (0.54-0.88), and 0.63 (0.48-0.81); P(trend) diets consistent with the DASH diet are associated with lower rates of HF.

    This meta-analysis reviewed existing data on the impact of work-related critical incidents in hospital-based health care professionals. Work-related critical incidents may induce post-traumatic stress symptoms or even post-traumatic stress disorder (PTSD), anxiety, and depression and may negatively affect health care practitioners' behaviors toward patients. Nurses and doctors often cope by working part time or switching jobs. Hospital administrators and health care practitioners themselves may underestimate the effects of work-related critical incidents. Relevant online databases were searched for original research published from inception to 2009 and manual searches of the Journal of Traumatic Stress, reference lists, and the European Traumatic Stress Research Database were conducted. Two researchers independently decided on inclusion and study quality. Effect sizes were estimated using standardized mean differences with 95% confidence intervals. Consistency was evaluated, using the I(2)-statistic. Meta-analysis was performed using the random effects model. Eleven studies, which included 3866 participants, evaluated the relationship between work-related critical incidents and post-traumatic stress symptoms. Six of these studies, which included 1695 participants, also reported on the relationship between work-related critical incidents and symptoms of anxiety and depression. Heterogeneity among studies was high and could not be accounted for by study quality, character of the incident, or timing of data collection. Pooled effect sizes for the impact of work-related critical incidents on post-traumatic stress symptoms, anxiety, and depression were small to medium. Remarkably, the effect was more pronounced in the longer than in the shorter term. In conclusion, this meta-analysis supports the hypothesis that work-related critical incidents are positively related to post-traumatic stress symptoms, anxiety, and depression in hospital-based health care professionals

    Antibiotic resistance has become a global issue, with 700,000 deaths attributable to multidrug-resistance (MDR) occurring each year. Centers for Disease Control and Prevention (CDC) show rapidly increasing rates of infection due to antibiotic-resistant bacteria. The aim of the study isto describe the incidence of MDR, extensively drug-resistant (XDR) and pan drug-resistant (PDR) in Enterococcus spp., Staphylococcus aureus, K. pneumonia, Acinetobacter baumanii, P. aeruginosin, and Enterobacter spp. (ESKAPE) pathogens in children admitted to Dr. Hasan Sadikin Hospital. All pediatric patients having blood culture drawn from January 2015 to December 2016 were retrospectively studied. Data include the number of drawn blood culture, number of positive results, type of bacteria, sensitivity pattern. International standard definitions for acquired resistance by ECDC and CDC was used as definitions for MDR, XDR and PDR bacteria. From January 2015 to December 2016, 299 from 2.542 (11.7%) blood culture was positive, with Staphylococcus aureus, Enterococcus spp., Enterobacteriaceae, Pseudomonas aeruginosa, Acinetobacter spp., respectively 5, 6, 24, 5, 20 with total 60 (20%). The MDR and XDR pathogen found were 47 and 13 patients, respectively.

    Cardiovascular (CV) diseases in general and heart failure (HF) in particular are major contributors to death and morbidity and are also recognized as important drivers of health care expenditure. The PARADIGM-HF trial was a pivotal trial designed to compare the long-term effects of LCZ696 with enalapril in patients with symptomatic HF with reduced ejection fraction (HFrEF). This review article presents an in-depth view of the PARADIGM-HF trial and the implications of the results in the management of patients with HF and is based on peer reviewed manuscripts, editorials, perspectives and opinions written about the PARADIGM-HF trial. The article presents the key safety and efficacy results of the trial with specific emphasis on the clinical implications of these findings. The review highlights the highly statistically significant, 20% reduction in the primary composite endpoint of cardiovascular death or HF hospitalization, and a 16% reduction in the risk of death from any cause. It also provides an overview of the design, clinical findings, limitations and special areas of clinical interest. The review discusses the future of LCZ696 and additional trials that seek to answer questions in other sub-populations of patients with HF. The article reiterates what has been concluded by many experts in the field of HF- the introduction of LCZ696 into routine clinical care, while dependent on the regulatory approvals in various countries as well as acceptance by physicians, payers and patients, will change the treatment landscape for patients with HFrEF.

    A 15-year postmarketing evaluation of the impact of varicella vaccine on the age distribution of varicella disease is being conducted at Kaiser Permanente Medical Care Program, Northern California (KPMCP). We report on a baseline assessment of the age-specific incidence and hospitalization rates of varicella and herpes zoster that was conducted before vaccine introduction. To assess the annual incidence of varicella, a telephone survey was conducted in a random sample of approximately 8,000 youths 5 to 19 years of age. The annual incidence of hospitalizations for varicella and herpes zoster in 1994 was assessed with the use of the computerized database at KPMCP. Varicella annual incidence was 10.3% in 5- to 9-year-olds, 1.9% in 10- to 14-year-olds and 1.2% in the 15- to 19-year age groups, respectively. Hospitalization rates among the entire KPMCP membership were 2.6 and 2.1 per 100,000 person years for varicella and zoster, respectively. Varicella incidence in the 15- to 19-year age group was higher among African-Americans than among Caucasians. Varicella rates were similar in the 5- to 9- and 10- to 14-year age groups to rates from other published studies conducted in 1972 to 1978, 1980 to 1988 and 1990 to 1992; however, the rate in 15- to 19-year-olds was 2 to 4 times higher than published rates in the same age category.

    Hemolytic uremic syndrome (HUS) is a serious health concern in children. HUS has primarily been linked to Escherichia coli O157:H7 infections, but non-O157 strains are gaining attention. Hemolytic anemia, thrombocytopenia, and acute renal failure are the characteristics of the syndrome. This study investigated the incidence of HUS at a regional Children's Hospital between 2001 and 2006 by retrospective review. Cases of HUS were investigated for outcomes based on stool culture and an association of acute pancreatitis. A total of 44 cases were identified, of which 57% were female and 43% were male, with an age distribution of 13 months to 17 years and a median age of 3.44 years. Data revealed 13 cases in 2006 compared to two cases in 2001, with 84% of all illnesses occurring in the summer and fall seasons. The median duration of thrombocytopenia was eight days and 50% of all cases required dialysis. E. coli O157:H7 was the predominant pathogen; however, 53% of the cases had unknown etiology. This data may suggest a growing number of cases from 2001 to 2006 and a role for agents other than E. coli O157:H7. E. coli O157:H7 caused longer intensive care unit (ICU) stay. No association between HUS and acute pancreatitis was found.

    There is little satisfactory evidence on the harm of safety incidents to patients, in terms of lost potential health and life-years. To estimate the healthy life-years (HLYs) lost due to 6 incidents in English hospitals between the years 2005/2006 and 2009/2010, to compare burden across incidents, and estimate excess bed-days. The study used cross-sectional analysis of the medical records of all inpatients treated in 273 English hospitals. Patients with 6 types of preventable incidents were identified. Total attributable loss of HLYs was estimated through propensity score matching by considering the hypothetical remaining length and quality of life had the incident not occurred. The 6 incidents resulted in an annual loss of 68 HLYs and 934 excess bed-days per 100,000 population. Preventable pressure ulcers caused the loss of 26 HLYs and 555 excess bed-days annually. Deaths in low-mortality procedures resulted in 25 lost life-years and 42 bed-days. Deep-vein thrombosis/pulmonary embolisms cost 12 HLYs, and 240 bed-days. Postoperative sepsis, hip fractures, and central-line infections cost incidents is roughly comparable with the UK burden of Multiple Sclerosis (80 DALYs per 100,000), HIV/AIDS and Tuberculosis (63 DALYs), and Cervical Cancer (58 DALYs). There were marked differences in the harm caused by the incidents, despite the public attention all of them receive. Decision makers can use the results to prioritize resources into further research and effective interventions.

    2012-10-01

    Full Text Available Introduction: Heart failure (HF is a common cardiovascular condition whose incidence and prevalence are increasing. Being a common reason for urgent hospital admission, it is a major cause of morbidity and mortality for the patients. In the developed countries coronary artery disease remains the leading cause of HF, whereas, in the underdeveloped countries, rheumatic heart disease leading to valvular lesion still remains the commonest causes of HF admission. The current study was designed to evaluate the clinical profile and medications prescribed reflecting the extent to which evidence based medicine is being practiced at our community. Methods: Clinical profile and prescribed medications of patients with diagnosis of HF who were admitted in the cardiology department of College of Medical Sciences & Teaching Hospital (CMS-TH, Bharatpur, Nepal, April 2010 to May 2012, were analyzed. A total of 255 patients presented with HF during the studied period were included. Results: Coronary artery disease, rheumatic heart disease, dilated cardiomyopathy, hypertensive heart failure, cor-pulmonale, and congenital heart disease leading to HF were found in 93 (36.5%, 65 (25.5%, 37 (14.5%, 22 (8.6%, 31 (12.2%,and 7 (2.7% patients respectively. The commonest presenting symptom was shortness of breath (81% and the commonest sign was bilateral basal crepitations (68%. From all patients, 89%, 64%, 51%, 16%, 48%, and 32% received loop diuretics, angiotensin-converting enzyme inhibitor, digoxin, angiotensin receptor blocker, spironolactone, and beta-blocking agents respectively. Conclusion: Coronary artery disease leading to HF was the commonest cause of HF admission in our centre. Despite current guidelines suggesting the use of beta-blocking agent in patients with HF, only 32% of our patients received this class of medications. Thus, many patients were not being managed fully in accordance with the evidence-based guidelines.

    To address the need for personalized prevention, we conducted a subject-level meta-analysis within the framework of the Heart "OMics" in AGEing (HOMAGE) study to develop a risk prediction model for heart failure (HF) based on routinely available clinical measurements. Three studies with elderly persons (Health Aging and Body Composition [Health ABC], Valutazione della PREvalenza di DIsfunzione Cardiaca asinTOmatica e di scompenso cardiaco [PREDICTOR], and Prospective Study of Pravastatin in the Elderly at Risk [PROSPER]) were included to develop the HF risk function, while a fourth study (Anglo-Scandinavian Cardiac Outcomes Trial [ASCOT]) was used as a validation cohort. Time-to-event analysis was conducted using the Cox proportional hazard model. Incident HF was defined as HF hospitalization. The Cox regression model was evaluated for its discriminatory performance (area under the receiver operating characteristic curve) and calibration (Grønnesby-Borgan χ 2 statistic). During a follow-up of 3.5 years, 470 of 10 236 elderly persons (mean age, 74.5 years; 51.3% women) developed HF. Higher age, BMI, systolic blood pressure, heart rate, serum creatinine, smoking, diabetes mellitus, history of coronary artery disease, and use of antihypertensive medication were associated with increased HF risk. The area under the receiver operating characteristic curve of the model was 0.71, with a good calibration (χ 2 7.9, P =0.54). A web-based calculator was developed to allow easy calculations of the HF risk. Simple measurements allow reliable estimation of the short-term HF risk in populations and patients. The risk model may aid in risk stratification and future HF prevention strategies. © 2017 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley.

    To determine the net economic impact of switching from low-osmolar contrast media (LOCM) to iso-osmolar contrast media (IOCM; iodixanol) in patients undergoing inpatient coronary or peripheral angioplasty in the United States (US). A budget impact model (BIM) was developed from a hospital perspective. Nationally representative procedural and contrast media prevalence rates, along with MARCE (major adverse renal cardiovascular event) incidence and episode-related cost data were derived from Premier Hospital Data (October 2014 to September 2015). A previously estimated relative risk reduction in MARCE associated with IOCM usage (9.3%) was applied. The higher cost of IOCM was included when calculating the net impact estimates at the aggregate, hospital type, and per hospital levels. One-way (±25%) and probabilistic sensitivity analyses identified the model's most important inputs. Based on weighted analysis, 513,882 US inpatient angioplasties and 35,610 MARCE cases were estimated annually. Switching to an "IOCM only" strategy from a "LOCM only" strategy increases contrast media cost, but prevents 2,900 MARCE events. The annual budget impact was an estimated saving of $30.71 million, aggregated across all US hospitals, $6,316 per hospital, or $60 per procedure. Net savings were maintained across all univariate sensitivity analyses. While MARCE/event-free cost differential was the most important factor driving total net savings for hospitals in the Northeast and West, procedural volume was important in the Midwest and rural locations. Switching to an "IOCM only" strategy from a "LOCM only" approach yields substantial net global savings to hospitals, both at the national level and within hospital sub-groups. Hospital administrators should maintain awareness of the factors that are likely to be more influential for their hospital and recognize that purchasing on the basis of lower contrast media cost may result in higher overall costs for patients undergoing inpatient

    Low literacy increases the risk for many adverse health outcomes, but the relationship between literacy and adverse outcomes in heart failure (HF) has not been well studied. We studied a cohort of ambulatory patients with symptomatic HF (NYHA Class II-IV within the past 6 months) who were enrolled in a randomized controlled trial of self-care training recruited from internal medicine and cardiology clinics at four academic medical centers in the US. The primary outcome was combined all-cause hospitalization or death, with a secondary outcome of hospitalization for HF. Outcomes were assessed through blinded interviews and subsequent chart reviews, with adjudication of cause by a panel of masked assessors. Literacy was measured using the short Test of Functional Health Literacy in Adults. We used negative binomial regression to examine whether the incidence of the primary and secondary outcomes differed according to literacy. Of the 595 study participants, 37 % had low literacy. Mean age was 61, 31 % were NYHA class III/IV at baseline, 16 % were Latino, and 38 % were African-American. Those with low literacy were older, had a higher NYHA class, and were more likely to be Latino (all p low literacy had an incidence rate ratio (IRR) of 1.39 (95 % CI: 0.99, 1.94) for all-cause hospitalization or death and 1.36 (1.11, 1.66) for HF-related hospitalization. After adjusting for demographic, clinical, and self-management factors, the IRRs were 1.31 (1.06, 1.63) for all-cause hospitalization and death and 1.46 (1.20, 1.78) for HF-related hospitalization. Low literacy increased the risk of hospitalization for ambulatory patients with heart failure. Interventions designed to mitigate literacy-related disparities in outcomes are warranted.

    The incidence and prevalence of obesity are increasing world wide. In the UK, obesity governmental strategy has primarily focused on prevention measures, with less focus on the demands of treating obese patients in hospital. Increasing service demand by obese patients coupled with a lack of adequate provision for care of these patients may lead to an increase in patient safety incidents. By classifying patient safety incidents associated with obesity reported to the National Patient Safety Agency, this report aims to identify areas for improvement in the quality and safety of care of the obese patient. A search of the National Reporting and Learning System database was conducted for all incidents caused by or relating to obesity for the period 1 January 2005 to 31 August 2008. The keywords 'obesity', 'overweight', 'BMI' (body mass index), and 'bariatric' were used. The relevant free text fields of the resulting set of incidents were then searched for the terms designed to isolate incidents occurring in anaesthesia, critical care, and surgery. Reported incidents were analysed and subsequently categorised to identify incident themes. Levels of harm were also established. 555 patient safety incidents were identified; 388 met inclusion criteria for analysis. 148 incidents were related to assessment, diagnosis or treatment, 213 related to infrastructure and 27 related to staffing. The majority of incidents were classified as no or low harm. Three deaths were reported, all within the domain of anaesthesia. This report identifies that the majority of safety incidents associated with obesity were related to infrastructure, suggesting that there is inadequate provision in place for the care of obese patients. While levels of harm were mostly low, the occurrence of incidents resulting in severe harm or death highlights the specific dangers associated with the care of the obese patient. A global approach to improving the safety of care delivery for obese patients is

    Crowd control is essential to the handling of mass-casualty incidents (MCIs). This is the task of the police at the site of the incident. For a hospital, responsibility falls on its security forces, with the police assuming an auxiliary role. Crowd control is difficult, especially when the casualties are due to riots involving clashes between rioters and police. This study uses data regarding the October 2000 riots in Nazareth to draw lessons about the determinants of crowd control on the scene and in hospitals. Data collected from formal debriefings were processed to identify the specifics of a MCI due to massive riots. The transport of patients to the hospital and the behavior of their families were considered. The actions taken by the Hospital Manager to control crowds on the hospital premises also were analyzed. During 10 days of riots (01-10 October 2000), 160 casualties, including 10 severely wounded, were evacuated to the Nazareth Italian Hospital. The Nazareth English Hospital received 132 injured patients, including one critically wounded, nine severely wounded, 26 moderately injured, and 96 mildly injured. All victims were evacuated from the scene by private vehicles and were accompanied by numerous family members. This obstructed access to hospitals and hampered the care of the casualties in the emergency department. The hospital staff was unable to perform triage at the emergency department's entrance and to assign the wounded to immediate treatment areas or waiting areas. All of the wounded were taken by their families directly into the "immediate care"location where a great effort was made to prioritize the severely injured. In order to control the events, the hospital's managers enlisted prominent individuals within the crowds to aid with control. At one point, the mayor was enlisted to successfully achieve crowd control. During riots, city, community, and even makeshift leaders within a crowd can play a pivotal role in helping hospital management

    This study aimed to identify temporal precursor and associated contributing factors for adverse clinical incidents in a hospital setting using the Human Factors Classification Framework (HFCF) for patient safety. A random sample of 498 clinical incidents were reviewed. The framework identified key precursor events (PE), contributing factors (CF) and the prime causes of incidents. Descriptive statistics and correspondence analysis were used to examine incident characteristics. Staff action was the most common type of PE identified. Correspondence analysis for all PEs that involved staff action by error type showed that rule-based errors were strongly related to performing medical or monitoring tasks or the administration of medication. Skill-based errors were strongly related to misdiagnoses. Factors relating to the organisation (66.9%) or the patient (53.2%) were the most commonly identified CFs. The HFCF for patient safety was able to identify patterns of causation for the clinical incidents, highlighting the need for targeted preventive approaches, based on an understanding of how and why incidents occur.

    There has been evidence in recent years that people with intellectual disabilities in acute hospitals are at risk of preventable deterioration due to failures of the healthcare services to implement the reasonable adjustments they need. The aim of this paper is to explore the challenges in monitoring and preventing patient safety incidents involving people with intellectual disabilities, to describe patient safety issues faced by patients with intellectual disabilities in NHS acute hospitals, and investigate underlying contributory factors. This was a 21-month mixed-method study involving interviews, questionnaires, observation and monitoring of incident reports to assess the implementation of recommendations designed to improve care provided for patients with intellectual disabilities and explore the factors that compromise or promote patient safety. Six acute NHS Trusts in England took part. Data collection included: questionnaires to clinical hospital staff (n = 990); questionnaires to carers (n = 88); interviews with: hospital staff including senior managers, nurses and doctors (n = 68) and carers (n = 37); observation of in-patients with intellectual disabilities (n = 8); monitoring of incident reports (n = 272) and complaints involving people with intellectual disabilities. Staff did not always readily identify patient safety issues or report them. Incident reports focused mostly around events causing immediate or potential physical harm, such as falls. Hospitals lacked effective systems for identifying patients with intellectual disabilities within their service, making monitoring safety incidents for this group difficult.The safety issues described by the participants were mostly related to delays and omissions of care, in particular: inadequate provision of basic nursing care, misdiagnosis, delayed investigations and treatment, and non-treatment decisions and Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) orders. The events leading to avoidable harm

Compelling evidence has shown that the incidence of cervical spondylosis increases with age. However, the relationship between age and the incidence of cervical spondylosis remains obscure. It is essential to note the relationship between age and the incidence of cervical spondylosis through more and more clinical data.Methods: In the case-controlled study reported here, retrospective clinical analysis of 1,276 cases of cervical spondylosis has been conducted. We analyzed the general clinical data, the relationship between age and the incidence of cervical spondylosis, and the relationship between age-related risk factors and the incidence of cervical spondylosis. A chi-square test was used to analyze the associations between different variables. Statistical significance was defined as a P-value of less than 0.05.Results: The imaging examination demonstrated the most prominent characteristic features of cervical spondylosis: bulge or herniation at C3-C4, C4-C5, and C5-C6. The incidence of cervical spondylosis increased with aging before age 50 years and decreased with aging after age 50 years, especially in the elderly after 60 years old. The occurrence rate of bulge or herniation at C3-C4, C4-C5, C5-C6, and C6-C7 increased with aging before age 50 years and decreased with aging after age 50 years, especially after 60 years. Moreover, the incidence of hyperosteogeny and spinal stenosis increased with aging before age 60 years and decreased with aging after age 60 years, although there was no obvious change in calcification.

    Full Text Available It has been suggested that the high incidence of ribotype 078 Clostridium difficile infections (CDI in the Netherlands is related to pig farming.We used data of hospitalised CDI patients (>2yrs of age diagnosed between May 2009 and May 2015 in 26 hospitals participating in a national sentinel surveillance. We compared clinical and geographical characteristics of 078 CDI to other CDI. We investigated the association between 078 CDI incidence and four indicators of pig farming (piglet, pig, piglet farm and pig farm density by mixed-effects Poisson regression. We used a space-time permutation model to search for community-onset 078 CDI clusters (using SaTScan.A total of 4,691 CDI were identified. Ribotype 078 was isolated in 493 of 3,756 patients (13.1% including a typing result. These patients had slightly higher community-onset disease and a 35% increase of 30-day mortality compared to non-078 CDI patients. The pooled overall and 078 incidence rates were 2.82 (95% CI, 2.42-3.29 and 0.26 (95% CI, 0.21-0.31 CDI per 10,000 patients-days respectively. Hospital 078 CDI incidence was not associated with provincial pig (IRR, 0.98; 95% CI, 0.89-1.08, piglet (IRR, 0.95; 95% CI, 0.75-1.19, pig farm (IRR, 1.08; 95% CI, 0.84-1.39, or piglet farm density (IRR, 1.00; 95% CI, 0.56-1.79. No clusters of community-onset ribotype 078 CDI were found.Our results do not indicate that the ribotype 078 CDI incidence in hospitals is related to pig (farm or piglet (farm density. However, transmission beyond provincial borders or in non-hospitalised patients cannot be excluded.

    Prostate cancer (PC) is the most prevalent among men and yet its risk factors are little known. This article aims to determine the hospital incidence, trend and municipal distribution of PC in Health Area of León (HAL). We included new cases of prostate cancer (ICD-9: 185, ICD-10: C61) enrolled in the Hospital Tumor Registry of the Complejo Asistencial Universitario de León, between 1996 to 2010 with residence in HAL. We calculated crude triennial hospital incidences and adjusted at global and European population. As denominator we used the INE population data disaggregated by five-year age groups of residents in municipalities of the HAL. To analyze the spatial distribution, we estimated municipal relative risks (RR) smoothed by fitting the Besag, York and Mollié model and the posterior probability (PP) of RR >1 using Bayesian methods. 3,366 cases were included. Standardized rates at European population amounted of 30.3 (1996-98) to 119.0 (2008-2010) new cases per 100,000 men. The number of organ-confined cases were increased from 281 (1999-2001) to 999 (2008-2010). PSA determinations amounted from 30,985 (1999-2001) to 117 396 (2008-2010). A great increase was observed in the frequency of PC at the expense of organ-confined cases which correlate very well with PSA determinations performed in HAL. There were no differences of interest in the municipal distribution incidences.

    Rotavirus is a leading cause of severe diarrhea among children worldwide. Thus, the World Health Organization recommended including rotavirus vaccines in national immunization programs. One concern about rotavirus vaccine, however, is a possible association with intussusception. Thus, it is crucial to know the baseline incidence of intussusception in the first year of life. A study conducted in Hanoi, Vietnam showed that the incidence of intussusception was the highest in the world. This retrospective cross-sectional study was undertaken to determine the incidence of intussusception among children Khanh Hoa Provincial General Hospital where virtually all cases of intussusception occurring in the city were assumed to have been encountered. The incidence of intussusception among children <1 year of age was 296 per 100,000 person-years (95% confidence interval [CI]: 225–382), and that among children <5 years of age was 196 per 100,000 person-years (95% CI: 169–226), confirming the high incidence of intussusception in Vietnam. Nevertheless, there was no intussusception in the first three months of life. We therefore recommend that the first dose of any rotavirus vaccine be administered to infants between 6 and 12 weeks of age. PMID:24155653

    1978-01-01

    The basic methods for extracting and determining Zr(4) and Hf(4) are described. Diantipyrinemethane and its alkyl homologs selectively extract Zr and Hf from HNO 3 solutions in the presence of nitrates. Zr is selectively extracted with tetraethyldiamide of heptyl phosphoric acid (in benzene) as well as with 2-thenoyltrifluoroacetone (in an acid). The latter reagents is suitable for rapid determination of 95 Zr in a mixture with 95 Nb and other fragments. The complexometric determination of Zr is based on formation of a stable complex of Zr with EDTA. The titration is carried out in the presence of n-sulfobenzene-azo-pyrocatechol, eriochrome black T. The determination is hindered by Hf, fluoride-, phosphate-, oxalate- and tartrate-ions. The method is used for determining Zr in zircon and eudialyte ore. Zr is determined photometrically with the aid of xylenol orange, arsenazo 3 and pyrocatechol violet (in phosphorites). Hf is determined in the presence of Zr photometrically with the aid of xylenol orange or methyl-thymol blue. The method is based on Zr being masked with hydrogen peroxide in the presence of sulfate-ions

    Worldwide, the frequency of invasive fungal infections has been increasing, with a corresponding increase in the numbers of high-risk patients. Exposure reduction through the use of high-efficiency particulate air (HEPA) filters has been the preferred primary preventive strategy for these high-risk patients. Although the efficiency and benefits of fixed HEPA filters is well proven, the benefits of portable HEPA filters are still inconclusive. This was a retrospective study to assess the impact of 48 portable HEPA filter units deployed in selected wards in Singapore General Hospital, an acute tertiary-care hospital in Singapore. Data were extracted between December 2005 and June 2008 on the diagnoses at discharge and microbiological and histological laboratory findings. All patients with possible, probable, or proven invasive aspergillosis (IA) were included. In wards with portable HEPA filters, the incidence rate of IA of 34.61/100,000 patient-days in the pre-installation period was reduced to 17.51/100,000 patient-days in the post-installation period (P = .01), for an incidence rate ratio of 1.98 (95% confidence interval [CI], 1.10-2.97). In wards with no HEPA filters, there was no significant change in the incidence rate during the study period. Portable HEPA filters were associated with an adjusted odds ratio of 0.49 (95% CI, 0.28-0.85; P = .01), adjusted for diagnosis and length of hospital stay. Portable HEPA filters are effective in the prevention of IA. The cost of widespread portable HEPA filtration in hospitals will be more than offset by the decreases in nosocomial infections in general and in IA in particular.

    Full Text Available Background: Currently, 93 million people are estimated as living with diabetic retinopathy (DR worldwide. The incidence, retinopathy-free survival time and associated factors of DR in developed countries have been well documented; but in Ethiopia, national data on incidence and associated factors of DR are lacking. Objective: The objective of this study is to determine incidence and factors associated with the development of DR among diabetic patients at Arbaminch General Hospital, Ethiopia. Materials and Methods: Longitudinal follow-up data analysis with record review of 400 diabetic patients was conducted at Arbaminch General Hospital. Among 400 diabetic patients, 270 diabetic patients with baseline information and without a history of hypertension at baseline were included in this study. Whereas, pregnancy induced diabetes and patients with retinopathy at baseline were excluded from this study. Consecutive sampling technique was applied to select study participants. Data of cohorts were extracted from medical record using pre-tested structured extraction checklist. Data cleaning, coding, categorising, merging and analysis carried out by STATA version 12. Descriptive statistics was done and summarised accordingly. Bivariate Cox proportional hazard regression analysis was done to select potential candidates for the full model atP ≤ 0.25 and multivariable Cox proportional hazard regression analysis was made to estimate the independent effect of predictors on the incidence of DR. Model diagnostic tests were performed and final model fitness was checked by Cox and Snell residuals; finally, statistical significance was tested atP 12 years. Adjusted analysis showed that the hazard of developing DR was statistically and positively associated with baseline age, baseline systolic blood pressure (SBP level and fasting blood glucose (FBG level. Conclusion: In the current study, the incidence of DR was high. Since baseline age, baseline SBP level and

    Full Text Available BACKGROUND: The few studies that have examined the relationship between diabetes and bacterial infections have utilized administrative databases and/or have had limited/incomplete data including recognized infection risk factors. The aim of this study was to determine the incidence and associates of bacterial infection severe enough to require hospitalization in well-characterized community-based patients with type 2 diabetes. METHODS AND FINDINGS: We studied a cohort of 1,294 patients (mean±SD age 64.1±11.3 years from the longitudinal observational Fremantle Diabetes Study Phase I (FDS1 and 5,156 age-, gender- and zip-code-matched non-diabetic controls. The main outcome measure was incident hospitalization for bacterial infection as principal diagnosis between 1993 and 2010. We also examined differences in statin use in 52 FDS1 pairs hospitalized with pneumonia (cases or a contemporaneous non-infection-related cause (controls. During 12.0±5.4 years of follow-up, 251 (19.4% patients were hospitalized on 368 occasions for infection (23.7/1,000 patient-years. This was more than double the rate in matched controls (incident rate ratio (IRR (95% CI, 2.13 (1.88-2.42, P<0.001. IRRs for pneumonia, cellulitis, and septicemia/bacteremia were 1.86 (1.55-2.21, 2.45 (1.92-3.12, and 2.08 (1.41-3.04, respectively (P<0.001. Among the diabetic patients, older age, male sex, prior recent infection-related hospitalization, obesity, albuminuria, retinopathy and Aboriginal ethnicity were baseline variables independently associated with risk of first hospitalization with any infection (P≤0.005. After adjustment for these variables, baseline statin treatment was not significant (hazard ratio (95% CI, 0.70 (0.39-1.25, P = 0.22. Statin use at hospitalization for pneumonia among the case-control pairs was similar (23.1% vs. 13.5%, P = 0.27. CONCLUSIONS: The risk of severe infection is increased among type 2 diabetic patients and is not reduced by statin

    The increased morbidity and mortality associated with nosocomial infections in the intensive care unit (ICU) is a matter of serious concern today. To determine the incidence of nosocomial infections acquired in the ICU, their risk factors, the causative pathogens and the outcome in a tertiary care teaching hospital. This was a prospective observational study conducted in a 12 bedded combined medical and surgical ICU of a medical college hospital. The study group comprised 242 patients admitted for more than 48 h in the ICU. Data were collected regarding severity of the illness, primary reason for ICU admission, presence of risk factors, presence of infection, infecting agent, length of ICU and hospital stay, and survival status and logistic regression analysis was done. The nosocomial infection rate was 11.98% (95% confidence interval 7.89-16.07%). Pneumonia was the most frequently detected infection (62.07%), followed by urinary tract infections and central venous catheter associated bloodstream infections. Prior antimicrobial therapy, urinary catheterization and length of ICU stay were found to be statistically significant risk factors associated with nosocomial infection. Nosocomial infection resulted in a statistically significant increase in length of ICU and hospital stay, but not in mortality. Nosocomial infections increase morbidity of hospitalized patients. These findings can be utilized for planning nosocomial infection surveillance program in our setting.

    We sought to document the incidence of pediatric hospitalization for bacterial pneumonia before universal childhood conjugate pneumococcal vaccination using two different methods of diagnosis. By following the World Health Organization (WHO) chest radiography (CXR) protocol, two radiologists independently read the CXRs of a cohort of systematically recruited children younger than 5 years. The children had acute respiratory infections and were admitted to one of two hospitals that care for 72.5% of all pediatric admissions on Hong Kong Island. Medical records were reviewed for clinical manifestation and to identify bacterial pneumonia diagnosed by pediatricians. In children younger than 5 years, the incidences of bacterial pneumonia, as diagnosed by pediatricians and by the WHO CXR standard, were 775.7 per 100,000 population [95% confidence interval (CI, 591.8-998.3)] and 439.5 per 100,000 population (95% CI, 304.6-614.5), respectively. The study period was from 2002 to 2004. This study provided a reliable baseline estimate of the hospitalization burden of pneumococcal pneumonia in Hong Kong children before the advent of universal conjugate pneumococcal vaccination.

METHODS This is a prospective population-based single centre observational study of all patients diagnosed with benign perforated peptic ulcer; included were both gastric and duodenal ulcer patients admitted to Maharaja Yeshwantrao Hospital, Indore, between September 2013 and September 2015. Ulcers with a malignant neoplasia diagnosis verified by histology after biopsy, traumatic perforation, and perforation of age group >45 and 40 years, the incidence increased over 4 times and mortality more than 12 times compared to younger age <20 years. After 1 month followup, out of 172 discharged patients, 145 (84% patients came with symptoms resolved or having no complication. After 2 months followup, 158 (92% patients came with symptoms resolved and 166 (96% patients changed their dietary habits and lifestyle. CONCLUSION The incidence rate and mortality rate was stable. In our study, we found male preponderance, may be due to their lifestyle changes. Maximum number patients are found in age group 41-45 years. As in all previous studies, as age advances, incidence of peptic perforation also increases. Also, found strong relationship between consumption of oily or spicy food and non-vegetarian food with incidence of peptic perforation. Relation of peptic perforation with NSAIDs, smoking, and alcoholism follows same trends as in previous studies.

    Previous sports injury is a known risk factor for subsequent osteoarthritis (OA), but population-based rates of sports injury are unknown. The aims of this study were to: (1) describe the trends in the population incidence and burden of all hospital-treated sports injury in Victoria, Australia in adults aged 15+ years; (2) determine the incidence of lower limb and knee injuries; and (3) quantify their population health burden as average direct hospital costs per injury and lengths of stay. Health sector data relating to adults aged 15+ years, for 2004-2010 inclusive, was extracted from the Victorian Admitted Episodes Dataset (VAED) and Victorian Emergency Minimum Dataset (VEMD). Data relating to sports injuries were identified using activity codes in each dataset Trends in injury frequency and rates were determined, and economic burden was calculated. The overall annual rate of hospital treated sports injuries increased by 24% (P = 0.001), and lower limb injuries by 26% (P = 0.001) over the 7 years. The associated accumulated economic burden was $265 million for all sports injuries and $110 million for lower limb injuries over the 7-years. The findings of this study show a significant increase in sports injuries in the state of Victoria, Australia over a 7-year period. As previous sports injury is a risk factor for the development of OA, the future incidence of OA will escalate, placing an even greater burden on health care systems. Population-wide preventative strategies that reduce the risk of sports injury are urgently required in order to reduce the future burden of OA.

    The aim of the study was to assess the epidemiology, the incidence of multidrug-resistant bacteria and bloodstream infections' (BSIs) seasonality in a university hospital. This retrospective study was carried out in the University General Hospital of Patras, Greece, during 2011-13 y. Blood cultures from patients with clinical presentation suggestive of bloodstream infection were performed by the BacT/ALERT System. Isolates were identified by Vitek 2 Advanced Expert System. Antibiotic susceptibility testing was performed by the disk diffusion method and E-test. Resistance genes (mecA in staphylococci; vanA/vanB/vanC in enterococci; bla KPC /bla VIM /bla NDM in Klebsiella spp.) were detected by PCR. In total, 4607 (9.7%) blood cultures were positive from 47451 sets sent to Department of Microbiology, representing 1732 BSIs. Gram-negative bacteria (52.3%) were the most commonly isolated, followed by Gram-positive (39.5%), fungi (6.6%) and anaerobes bacteria (1.8%). The highest contamination rate was observed among Gram-positive bacteria (42.3%). Among 330 CNS and 150 Staphylococcus aureus, 281 (85.2%) and 60 (40.0%) were mecA-positive, respectively. From 113 enterococci, eight were vanA, two vanB and two vanC-positives. Of the total 207 carbapenem-resistant Klebsiella pneumoniae (73.4%), 202 carried bla KPC , four bla KPC and bla VIM and one bla VIM . A significant increase in monthly BSIs' incidence was shown (R2: 0.449), which may be attributed to a rise of Gram-positive BSIs (R2: 0.337). Gram-positive BSIs were less frequent in spring (P period. The increasing incidence of BSIs can be attributed to an increase of Gram-positive BSI incidence, even though Gram-negative bacteria remained the predominant ones. Seasonality may play a role in the predominance of Gram-negative's BSI.

    Full Text Available Aboriginal people in British Columbia (BC have higher injury incidence than the general population. Our project describes variability among injury categories, time periods, and geographic, demographic and socio-economic groups. This report focuses on unintentional falls.We used BC's universal health care insurance plan as a population registry, linked to hospital separation and vital statistics databases. We identified Aboriginal people by insurance premium group and birth and death record notations. We identified residents of specific Aboriginal communities by postal code. We calculated crude incidence and Standardized Relative Risk (SRR of hospitalization for unintentional fall injury, standardized for age, gender and Health Service Delivery Area (HSDA, relative to the total population of BC. We tested hypothesized associations of geographic, socio-economic, and employment-related characteristics with community SRR of injury by linear regression.During 1991 through 2010, the crude rate of hospitalization for unintentional fall injury in BC was 33.6 per 10,000 person-years. The Aboriginal rate was 49.9 per 10,000 and SRR was 1.89 (95% confidence interval 1.85-1.94. Among those living on reserves SRR was 2.00 (95% CI 1.93-2.07. Northern and non-urban HSDAs had higher SRRs, within both total and Aboriginal populations. In every age and gender category, the HSDA-standardized SRR was higher among the Aboriginal than among the total population. Between 1991 and 2010, crude rates and SRRs declined substantially, but proportionally more among the Aboriginal population, so the gap between the Aboriginal and total population is narrowing, particularly among females and older adults. These community characteristics were associated with higher risk: lower income, lower educational level, worse housing conditions, and more hazardous types of employment.Over the years, as socio-economic conditions improve, risk of hospitalization due to unintentional fall

    Full Text Available Streptococcus pneumoniae is an important cause of morbidity and mortality in Southeast Asia, but regional data is limited. Updated burden estimates are critical as pneumococcal conjugate vaccine (PCV is highly effective, but not yet included in the Expanded Program on Immunization of Thailand or neighboring countries.We implemented automated blood culture systems in two rural Thailand provinces as part of population-based surveillance for bacteremia. Blood cultures were collected from hospitalized patients as clinically indicated.From May 2005- March 2010, 196 cases of pneumococcal bacteremia were confirmed in hospitalized patients. Of these, 57% had clinical pneumonia, 20% required mechanical ventilation, and 23% (n = 46 died. Antibiotic use before blood culture was confirmed in 25% of those with blood culture. Annual incidence of hospitalized pneumococcal bacteremia was 3.6 per 100,000 person-years; rates were higher among children aged <5 years at 11.7 and adults ≥65 years at 14.2, and highest among infants <1 year at 33.8. The median monthly case count was higher during December-March compared to the rest of the year 6.0 vs. 1.0 (p<0.001. The most common serotypes were 23F (16% and 14 (14%; 61% (74% in patients <5 years were serotypes in the 10-valent PCV (PCV 10 and 82% (92% in <5 years in PCV 13. All isolates were sensitive to penicillin, but non-susceptibility was high for co-trimoxazole (57%, erythromycin (30%, and clindamycin (20%.We demonstrated a high pneumococcal bacteremia burden, yet underestimated incidence because we captured only hospitalized cases, and because pre-culture antibiotics were frequently used. Our findings together with prior research indicate that PCV would likely have high serotype coverage in Thailand. These findings will complement ongoing cost effectiveness analyses and support vaccine policy evaluation in Thailand and the region.

    Full Text Available Background and Aims: Cardiac arrest has multifactorial aetiology and the outcome depends on timely and correct interventions. We decided to investigate the circumstances, incidence and outcome of cardiopulmonary resuscitation (CPR at a tertiary hospital in India, in relation to various factors, including extensive basic life support and advanced cardiac life support training programme for all nurses and doctors. Methods: It has been over a decade and a half with periodical updates and implementation of newer guidelines prepared by various societies across the world about CPR for both in-hospital and out-of hospital cardiac arrests (IHCA and OHCA. We conducted a prospective study wherein all cardiac arrests reported in the hospital consecutively for 12 months were registered for the study and followed their survival up to 1-year. Statistical analysis was performed by using Chi-square test for significant differences in proportions applied to various parameters of the study. Results: The main outcome measures were; (following CPR return of spontaneous circulation, survival for 24 h, survival from 24 h to 6 weeks or discharge, alive at 1-year. For survivors, an assessment was made about their cerebral performance and overall performance and accordingly graded. All these data were tabulated. Totally 419 arrests were reported in the hospital, out of which 413 were in-hospital arrests. Out of this 260 patients were considered for resuscitation, we had about 27 survivors at the end of 1-year follow-up (10.38%. Conclusion: We conclude by saying there are many factors involved in good clinical outcomes following IHCAs and these variable factors need to be researched further.

    Variation in incidence is a universal feature of out-of-hospital cardiac arrest (OHCA). One potential source of variation is the rurality of the location where the OHCA incident occurs. While previous work has used a simple binary approach to define rurality, the purpose of this study was to use a categorical approach to quantify the impact of urban-rural classification on OHCA incidence in the Republic of Ireland. The observed versus expected ratio of OHCA incidence where resuscitation was attempted for the period January 1, 2012, to December 31, 2014, was calculated for each of the 3,408 electoral divisions (ED). EDs were then classified into 1 of 6 urban-rural classes. Multilevel modeling was used to test for variation in incidence ratios (IR) across the urban-rural classes. A total of 4,755 cases of adult OHCA, not witnessed by Emergency Medical Services, where resuscitation was attempted were included in the study. The number of EDs in each category was as follows: city (n = 477); town (n = 293); near village (n = 182); remote village (n = 84); near rural (n = 1,479); remote rural (n = 893). The IR per ED varied from 0 to 18.38 (EDs, n = 3,408). Multilevel modeling showed that 2.36% of variation in IR was due to urban-rural classification. This dropped to 0.45% when adjusted for ED deprivation score and median distance to an ambulance station. The addition of other explanatory variables did not improve the model. OHCA variation in Ireland is limited and almost fully explained by area-level deprivation and proximity to ambulance stations. © 2017 National Rural Health Association.

    Indonesia is the second largest number of tuberculosis (TB) in the world. Isoniazid Preventive Therapy (IPT) as one of the three I’s TB-HIV collaboration to manage TB in people living with HIV / AIDS (PLHIV) has not been fully performed. It is related to doubt to get rid of TB in PLHIV. This study aims to see the effect of IPT on the incidence of TB in PLHIV. This issue is a retrospective cohort study based on medical record data in HIV clinic. Inclusion criteria are PLHIV ≥ 15 years of age who were registered to visit the CST service and obtain IPT with good adherence if they were receiving ART. Of 462 patients, HIV- infected patients receiving IPT were 154 (33.3%). IPT administration has a protective effect on PLHIV where the rate of TB incidence in PLHIV who received IPT were 0.21 times lower than those who did not receive IPT (IRR = 0.21, 95% CI 0.023-0.881, p 0.008). In this population, IPT administration reduces 79% risk of PLHIV to suffer TB.IPT administration reduces the incidence of TB.

    Full Text Available A two-site WERA HF radar station was installed in November 2009 at the eastern coast of Lemnos Island in North Aegean Sea, aiming to monitor the surface inflow of Black Sea waters exiting from the Dardanelles Strait, as well as to constitute a coastal management tool for incidents of oil-pollution or save-and-rescue operations. Strong interference by foreign transmissions is a source of noise deteriorating the quality of the backscattered signal, thus significantly reducing the HF radar’s effective data return rate. In order to ameliorate this problem, further quality-control and data gap interpolating procedures have been developed and applied, to be used in addition to the procedures incorporated and used by the manufacturer’s signal processing software. The second-level processing involves traditional despiking in the temporal domain, preceding Empirical Orthogonal Function analysis. The latter is used not only to filter high-frequency noise but also to fill data gaps in time and space. The data reconstruction procedure has been assessed via comparison of (a HF radial with CODE-type drifter radial velocities as well as (b HF-derived virtual drifter tracks with actual drifter tracks. The main circulation features and their variability, as revealed by the reconstructed fields, are presented.

    Full Text Available Giardia lamblia is one of the most prevalent intestinal flagellate protozoa that infects a wide range of vertebrate hosts causing severe intestinal disorder in children.This study was performed to determine subspecies of G.lamblia by the PCR-RFLP method, targeting the glutamate dehydrogenase(gdhlocus, in hospitalized children at Urmia Mutahhari Hospital, West Azerbaijan Province,Iran and determining the infection transformational storages in this area.Overall, 720 stool specimens were collected from the hospitalized children, 34 samples were positive and Giardia cysts were detected under the microscope. Cysts were partially purified by the sucrose density gradient method and then washed with sterile distilled water to remove effectively the PCR inhibitors. Genomic DNA of G. lamblia isolates was extracted by freeze-thaw cycles followed by phenol/ chloroform/isoamyl alcohol method. The single step PCR-RFLP assay was used to differentiate the assemblages between A and B, which were found in humans. In this method, 432 bp expected size was amplified, and then for detection of subspecies, specific restriction RsaI and BspLI enzymes were used.Totally 34 samples were positive in terms of Giardia cyst out of 720 examined samples microscopically, so the parasite spread rate is reported 4.72%. Analysis PCR-RFLP on these samples revealed that 28 samples (93.3% have the genotype BIII and 2 samples (6.7% belong to the subgroup BIV.PCR-RFLP is a proper analytical method for determining the genotype among parasite types, using the glutamate dehydrogenizes zone's genes. Based on the results, an animal origin of infection cycle is suggested.

    Parenteral feeding is the basic way of nutrition in the first day of life in infants with very low birth weight. Due to its instability glutamine is not included in aminoacid solutions used for parenteral nutrition. Meanwhile glutamine is an important aminoacid, which plays a major role in the maturation of the gastrointestinal tract as well as the immunological system. The aim of our study was to estimate if glutamine supplementation of parenteral nutrition in neonates with the very low birth weight can decrease the incidence of necrotizing enterocolitis -- NEC (> 1 degree according to the Bell criteria), nosocomial sepsis, and shorten the total length of hospitalization. Prospective, randomized study included 55 neonates born between 26 and 32 weeks of gestation, with birth weight range of 580 g to 1250 g. On the third day of life patients were randomized into 2 groups. Each group was fed with a different aminoacid solution. Group 1 consisted of patients who received a standard aminoacid solution with an addition of glutamine dipeptide (20% of total amount of aminoacids). Group 2 (acknowledged as the control group) including 30 patients received a standard aminoacid solution. Glutamine and glutaminic acid levels were checked in the cord blood, and on the 3rd and 14th day of life. Venous samples were taken at 8 a.m. and were estimated using HPLC. The Ethics Committee of the Warsaw Medical University had approved the research. In group 1 nosocomial sepsis had occurred in 7/25 neonates, and in the control group in 11/30; NEC was diagnosed in none of the 25 neonates in group 1 and in 5/30 of the control group; the total length of hospitalization in group 1 was 75 days (median 70) versus 73 in the control group (median 70). The lowest glutamine concentration was noted in cord blood samples, and increased on the third day of life in both groups. There were a statistically significant difference among the levels of glutamine concentration between the cord sample and the

    Full Text Available Globally, death of women due to HIV/AIDS related causes during pregnancy or within 42 days after pregnancy was estimated to be 37,000. In Ethiopia, 42,900 pregnant women living with HIV gave birth in the year 2011. This study was aimed to assess incidence and predictors of pregnancy among women on ART in Debre Markos Referral Hospital, Northwest Ethiopia. A retrospective cohort study was conducted using data recorded from September 2011 to August 2015. Data was extracted from February to March, 2016, from 1,239 records and analyzed using SPSS version 16. A Kaplan-Meier survival analysis was used to estimate the probabilities of being pregnant. The Cox proportional hazards model was done and results were expressed using hazard ratios with 95% CI. A total of 1,239 women on ART were included in the study. The incidence of pregnancy was 49.2 per 1,000 person-years. Living in rural, being married, being widowed, being unemployed, and having <2 children at enrollment were found to be positively associated with being pregnant. The incidence of pregnancy among women on ART was found to be considerable. Provision of family planning and other reproductive health interventions have to be coupled with the ART service to address the problem.

    Full Text Available Objective: To determine the incidence of Dirofilaria immitis (D. immitis in dogs using the wet mount and buffy coat techniques for rapid detection of microfilaria in blood samples collected from dogs, to compare the two techniques for quick detection, to find if there is age susceptibility in the incidence of dirofilariasis in dogs presented at the Veterinary Teaching Hospital, University of Nigeria, Nsukka and to find out if there are breed and sex variations in the incidence of dirofilariasis in dogs presented at Veterinary Teaching Hospital, University of Nigeria, Nsukka. Methods: Blood samples were collected from the cephalic vein of 119 dogs. The blood samples were aseptically collected via cephalic venepuncture of each dog, collected into a tube containing ethylene diamine tetraacetic acid as anticoagulant, stored in an ice pack box at 5 °C and processed and examined for microfilaria using wet mount and buffy coat techniques. Results: A total of 4 dogs were positive for D. immitis microfilaria giving a prevalence of 3.36%, more male (4.83% than female (1.75% dogs were affected in this study. Although there was no significant difference between both groups, the prevalence was the highest in cross breeds (6.66%, moderate in local breeds (3.63% and absent in exotic breeds (0.00%. Although there was no significant (P < 0.05 difference amongst the 3 groups, only adult dogs were found positive for D. immitis microfilaria. Conclusions: Based on the results of this present study, both the wet mount and buffy coat techniques can be used at the discretion of the clinician and in the absence of modified Knott’s filter test, ELISA test and other diagnostic imaging techniques, in the rapid detection of microfilaria in blood samples from suspected cases of dirofilariasis.

    Sepsis is amongst the leading causes of admission to the intensive care units and is associated with a high mortality. However, data from developing countries is scares. Aim of conducting this study was to determine the incidence, outcome and risk factors for sepsis on admission to surgical intensive care unit (SICU) of a teaching hospital in Pakistan. Two year retrospective observational study included all consecutive adult admissions to the surgical intensive care unit (SICU) of a University Hospital, from January 2012 to December 2013. Two hundred and twenty-nine patients met the inclusion criteria. Average age of the patients was 46.35 ± 18.23 years (16-85), mean Acute Physiology and Chronic Health Evaluation II (APACHE II) score was 15.92 ± 8.13 and males were 67.6%. Median length of ICU stay was 4 [IQR 5]. 43% patients fulfilled the criteria of sepsis at the time of admission to the SICU and incidence of severe sepsis/septic shock was 35%. Abdominal sepsis was the most frequent source of infection (57.5%). The overall intensive care unit mortality was 32.31% but the mortality of sepsis-group was 51.15% as compared to 17.7% of the non- sepsis group. Stepwise logistic regression model showed that increasing age, female gender, non-operative admission, admission under general surgery and co-morbidities like ischaemic heart disease and chronic kidney disease were significant predictors of sepsis. The incidence of sepsis and severe sepsis/septic shock, on admission to SICU is high and mortality of the sepsis group is nearly three times the mortality of the non-sepsis group.

    The HF molecule is a key tracer of molecular hydrogen in diffuse interstellar medium (ISM). Accurate modeling of the HF abundance in such media requires to model its excitation by both radiation and collisions. In diffuse ISM, the dominant collisional partners are atomic and molecular hydrogen. We report quantum time-independent calculations of collisional cross sections and rate coefficients for the rotational excitation of HF by H. The reactive hydrogen exchange channels are taken into account in the scattering calculations. For the first time, HF-H rate coefficients are provided for temperature ranging from 10 to 500 K. The strongest collision-induced rotational HF transitions are those with Δj = 1 and the order of magnitude of the new HF-H rate coefficients is similar to that of the HF-H2 ones previously computed. As a first application, we simulate the excitation of HF by both H and H2 in typical diffuse ISM. We show that, depending on the rotational transition, hydrogen atoms increase or decrease the simulated excitation temperatures compared to collisional excitation only due to H2 molecules. Such result suggest that the new HF-H collisional data have to be used for properly modeling the abundance of HF in diffuse ISM.

    Background Worldwide, Indigenous people have disproportionately higher rates of transport injuries. We examined disparities in injury-related hospitalizations resulting from transport incidents for three population groups in British Columbia (BC): total population, Aboriginal off-reserve, and Aboriginal on-reserve populations. We also examined sociodemographic, geographic and ethnic risk markers for disparities. Methods We identified Aboriginal people through BC’s universal health care insurance plan insurance premium group and birth and death record notations. We calculated crude incidence rate and Standardized Relative Risk (SRR) of hospitalization for unintentional transport injury, standardized for age, gender and Health Service Delivery Area (HSDA), relative to the total population of BC. We tested hypothesized associations of geographic, socio-economic, and employment-related characteristics of Aboriginal communities with SRR of transport injury by multivariable linear regression. Results During the period 1991–2010, the SRR for the off-reserve Aboriginal population was 1.77 (95% CI: 1.71 to 1.83); and 2.00 (95% CI: 1.93 to 2.07) among those living on-reserve. Decline in crude rate and SRRs was observed over this period among both the Aboriginal and total populations of BC, but was proportionally greater among the Aboriginal population. The best-fitting multivariable risk marker model was an excellent fit (R2 = 0.912, ppopulation per room, proportion of the population with a high school certificate, proportion of the population employed; and multiplicative interactions of Aboriginal ethnicity with population per room and proportion of the population employed. Conclusions Disparities in risk of hospitalization due to unintentional transport injury have narrowed. Aboriginal ethnicity modifies the effects of socioeconomic risk factors. Continued improvement of socioeconomic conditions and implementation of culturally relevant injury prevention interventions

    The aim of this study was to evaluate the effectiveness of implementing a physical therapy guideline for patients undergoing upper abdominal surgery (UAS) in reducing the incidence of atelectasis and length of hospital stay in the postoperative period. A "before and after" study design with historical control was used. The "before" period included consecutive patients who underwent UAS before guideline implementation (intervention). The "after" period included consecutive patients after guideline implementation. Patients in the pre-intervention period were submitted to a program of physical therapy in which the treatment planning was based on the individual experience of each professional. On the other hand, patients who were included in the post-intervention period underwent a standardized program of physical therapy with a focus on the use of additional strategies (EPAP, incentive spirometry and early mobilization). There was a significant increase in the use of incentive spirometry and positive expiratory airway pressure after guideline implementation. Moreover, it was observed that early ambulation occurred in all patients in the post-intervention period. No patient who adhered totally to the guideline in the post-intervention period developed atelectasis. Individuals in the post-intervention period presented a shorter length of hospital stay (9.2±4.1 days) compared to patients in the pre-intervention period (12.1±8.3 days) (p<0.05). The implementation of a physical therapy guideline for patients undergoing UAS resulted in reduced incidence of atelectasis and reduction in length of hospital stay in the postoperative period.

    To examine whether mental vulnerability, an enduring personality characteristic, predicts incident hospital-diagnosed ulcer over three decades. A population-based cohort study enrolled 3365 subjects with no ulcer history, ages 30-60, in 1982-3. Mental vulnerability, Helicobacter pylori IgG antibodies, socioeconomic status, and sleep duration were determined at baseline; non-steroidal antiinflammatory drug use, smoking, leisure time physical activity, and alcohol consumption both at baseline and in 1993-4. Hospital diagnoses of incident ulcer through 2011 were detected using the Danish National Patient Registry. Ulcers were diagnosed in 166 subjects, including 83 complicated by bleeding or perforation. Age-, gender-, and socioeconomic status-adjusted associations were significant for mental vulnerability (Hazard Ratio (HR) 2.0, 95% Confidence Interval 1.4-2.8), Helicobacter pylori (HR 1.7, CI 1.2-2.3), smoking (HR 2.0, CI 1.3-3.1), heavy drinking (HR 1.6, CI 1.1-2.4), abstinence (HR 1.6, CI 1.1-2.5), non-steroidal antiinflammatory drugs (HR 2.1, CI 1.5-3.0), and sedentary lifestyle (HR 1.9, CI 1.4-2.7). Adjusted for all behavioral mediators, the HR for mental vulnerability was 1.5 (CI 1.0-2.2, p = .04). Mental vulnerability raised risk in Helicobacter pylori seropositive subjects and those exposed to neither Helicobacter pylori nor non-steroidal antiinflammatory drugs; its impact was virtually unchanged when analysis was limited to complicated ulcers. A vulnerable personality raises risk for hospital-diagnosed peptic ulcer, in part because of an association with health risk behaviors. Its impact is seen in 'idiopathic' and Helicobacter pylori-associated ulcers, and in acute surgical cases.

    The mumps vaccine (Jeryl-Lynn-strain) was introduced in Spain in 1981, and a vaccination policy which included a second dose was added in 1995. From 1992-1999, a Rubini-strain based vaccine was administered in many regions but later withdrawn due to lack of effectiveness. Despite high levels of vaccination coverage, epidemics have continued to appear. We characterized the three epidemic waves of mumps between 1998 and 2014, identifying major changes in susceptible populations using Poisson regression. For the period 1998-2003 (P1), the most affected group was from 1 to 4years old (y) [Incidence Rate (IR)=71.7 cases/100,000 population]; in the periods 2004-2009 (P2) and 2010-2014 (P3) IR ratio (IRR) increased among 15-24y (P2=1.46; P3=2.68) and 25-34y (P2=2.17; P3=4.05). Hospitalization rate (HR), complication rate (CR) and neurological complication rate (NR) among hospitalized subjects decreased across the epidemics, except for 25-34y which increased: HR ratio (HRR) (P2=2.18; P3=2.16), CRR (P3=2.48), NRR (P3=2.41). In Spain mumps incidence increased, while an overall decrease of hospitalizations and severe complications occurred across the epidemics. Cohorts born during periods of low vaccination coverage and those vaccinated with Rubini-strain were the most affected populations, leading to a shift in mumps cases from children to adolescents and young adults; this also reveals the waning immunity provided by the mumps vaccine. Despite not preventing all mumps cases, the vaccine appears to prevent serious forms of the disease. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Full Text Available Abstract Background Almost all studies of pathologic fractures have been conducted based on patients with tumours and hospital-based data; however, in the present study, a nationwide epidemiological survey of pathologic fractures in Taiwan was performed and the medical utilization was calculated. Methods All claimants of Taiwan's National Health Insurance (NHI Program in 2008 were included in the target population of this descriptive cross-sectional study. The registration and inpatient expenditure claims data by admission of all hospitalized subjects of the target population were examined and the concomitant International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM diagnosis codes were evaluated and classified into seven major categories of fracture. Results A total of 5,244 incident cases of pathologic fracture were identified from the 2008 hospitalized patient claims data. The incidence of pathologic fracture of the humerus, distal radius/ulna, vertebrae, femoral neck, other part of the femur, and tibia/fibula was 0.67, 0.08, 10.58, 1.11, 0.56, and 0.11 per 100,000 people, respectively, and patients with those fractures were hospitalized for 43.9 ± 42.9, 31.1 ± 32.9, 29. 4 ± 34.4, 43.3 ± 41.2, 42.4 ± 38.1, and 42.0 ± 32.8 days, respectively, incurring an average medical cost of US$11,049 ± 12,730, US$9,181 ± 12,115, US$6,250 ± 8,021, US$9,619 ± 8,906, US$10,646 ± 11,024, and US$9,403 ± 9,882, respectively. The percentage of patients undergoing bone surgery for pathologic fracture of the humerus, radius/ulna, vertebrae, femoral neck, other part of the femur, and tibia/fibula was 31.2%, 44.4%, 11.3%, 46.5%, 48.4%, and 52.5% respectively. Conclusions Comparing Taiwan to other countries, this study observed for Taiwan higher medical utilization and less-aggressive surgical intervention for patients hospitalized with pathologic fractures.

    An electron impact mass spectrometer is used to study dissociative attachment in HCl, DCl, and HF at incident energies 0--4 eV. Target molecules in different excited nuclear states are prepared with an iridium oven source. The cross sections for Cl - /HCl, Cl - /DCl, and F - /HF all show an order of magnitude increase with each increase of vibrational quantum (v=0, 1, and 2). In Cl - /HCl the threshold cross section for the v=2 level at 0.1 eV reaches (7.8 +- 4.7) x 10 -15 cm 2 . Together, this large cross section and the recent potential-energy-curve calculations of HCl and HCl - show that the conventional theory of dissociative attachment may not be applicable here. A new mechanism for dissociative attachment is suggested

    Syncope causes 1-3% of all emergency department (ED) visits, a high percentage of hospitalisations and prolonged hospital stay; nevertheless, many cases remain unexplained. This study analysed the incidence of syncope at the ED of the University Hospital of Parma in the first half of 2008; then a sample of 200 patients admitted later for syncope into the ED ward was studied, in order to evaluate the efficacy of a brief observation unit and to validate the Osservatorio Epidemiologico della Sincope nel Lazio (OESIL) risk score as a tool to identify cardiogenic syncopes. As reported in the literature, syncope accounts for 2.3% of ED consultations and for 4.2% of total hospital admissions. A brief observation ward in the ED seems to have the necessary characteristics for managing most cases of syncope quickly (3.5 days). The final diagnosis was certain in 60%, suspected in 33% and unexplained in 7% of patients. The commonest forms of syncope were non-cardiogenic. Factors associated with cardiogenic syncope were previous syncopal events, lack of prodromal symptoms and a high OESIL risk score.

    Smart pumps are expected to prevent and reduce medication errors. The implementation of smart pumps requires a significant effort and collaboration of physicians, nurses, pharmacists, and other stakeholders. The main objective of this study was to evaluate the impact of new smart pumps on reported drug-related accidents and incidents (AIs). This is a descriptive retrospective pre-post study conducted at a women's and pediatric hospital with 500 beds. A strong multidisciplinary team (nurse, pharmacist, pharmacy resident, physician, biomedical technician, information technology technician, patient safety officer, manager) was involved in the planning, implementation, and monitoring technology implementation. A total of 1045 smart pumps were implemented in 2011 in our hospital. The reported number of AIs related to intravenous drug administration (AIIV) before and after the implementation of 1045 smart pumps were collected. A total of 2911 AI events related to medications, devices, and equipment were self-reported by clinical staff in the pre-phase (Y0), 3523 in the post-phase (Y1), and 2788 in the post-phase (Y2). The total AIIV increased from 1432 in Y0 to 1834 in Y1 and decreased to 1389 in Y2. We observed no risk reduction associated with the implementation of smart pumps in a 500 bed mother-child hospital. Further studies are required to explore the details of the potential risk reduction associated with the use of smart pumps.

    Conclusions: The results of this study showed that the frequency of NI in the investigated hospital was not higher than in many other reported surveillance results from other countries. This, however, might be a bias as the administration of antibiotics was very high in this study and the quality of microbiological investigation might have influenced significantly, resulting in more false-negative results than expected. Overall, the use of the Iranian National Nosocomial Infection Surveillance System Software proved to be useful and allowed both rapid data collection and detailed data analysis.

    BACKGROUND: Patient-controlled analgesia (PCA) is a common and effective means of managing post-operative pain. We sought to identify factors that may lead to critical incidents (CIs) in patient safety when using PCA in our institution. METHODS: An observational study of prospectively collected data of patients who received PCA from 2002 to 2006 was performed. All CIs were documented and analysed by staff members of the acute pain service (APS). Cause analysis of CIs was undertaken to determine if measures can be instituted to prevent recurrence of similar events. RESULTS: Over eight thousand patients (8,240) received PCA. Twenty-seven CIs were identified. Eighteen were due to programming errors. Other CIs included co-administration of opioids and oversedation. CONCLUSION: In our institution, the largest contributory factor to CIs with PCAs was programming error. Strategies to minimize this problem include better education and surveillance.

    Full Text Available Carbapenem-resistant Enterobacteriaceae (CRE infections have emerged as a serious threat to health worldwide. They are associated with increased morbidity and mortality and are capable of silently colonizing the gastrointestinal tract. Because of this, there is great interest to characterize the epidemiology of CRE carriage and acquisition in healthcare facilities. The aim of this study was to determine the prevalence and factors associated with CRE fecal carriage (CRE-fc, and risk factors for incident cases.A cohort study was conducted at a tertiary care hospital from January 1st to April 30th, 2014 during a CRE outbreak. Weekly rectal swabs were performed in patients considered at risk until discharge. CRE-fc prevalence was 10.9% (CI 95% 7.7-14.7 among 330 patients. Treatment with carbapenems (OR 2.54, CI 95% 1.15-5.62; transfer from an institution (OR 2.16, CI 95% 1.02-4.59; multi-drug resistant infection within the previous six months (OR 2.81, CI 95% 1.47-5.36; intensive care unit admission (OR 0.42, CI 95% 0.20-0.88; hematologic malignancy (OR 4.02, CI 95% 1.88-8.06; invasive procedures (OR 2.18, CI 95% 1.10-4.32; and sharing a room with a known CRE carrier (OR 3.0, CI 95% 1.43-6.31 were independently associated factors for CRE-fc. Risk factors associated with CRE-fc incidence were determined for 87 patients initially negative and with subsequent screening; the incidence rate was 2.5 cases, per 1000 person-years (CI 95% 1.5-3.9. Independently associated risk factors were carbapenem treatment (HR 2.68, CI 95% 1.03-6.98, hematologic malignancy (HR 5.74, 95% CI 2.46-13.4 and a mean daily colonization pressure ≥10% (HR 5.03, IC 95% 1.77-14.28. OXA-48-like (OXA-232 and CTX-M-15 were the predominantly identified mechanisms of resistance.We found an elevated incidence and prevalence of CRE-fc in our hospital. Hematologic patients need to be considered a population at risk, and antibiotic stewardship along with infection control programs need to

    Oral manifestations in HIV infections are numerous and some of these are acknowledged as being of great importance in the early diagnosis of the disease. Many HIV-associated oral infections occur early in HIV disease, not infrequently as the presenting sign or symptom. Thus, early detection of the associated oral opportunistic infections should, in many cases, result in earlier diagnosis of HIV infection. Cytology, a simple, painless, and inexpensive method, has become a preferred method and was used in our study for early diagnosis of certain lesions. To determine the effect of highly active antiretroviral therapy on incidence rate of opportunistic infections among HIV-positive adults in a teaching hospital in India, a prospective study was conducted and the required sample size was 40. Study participants were selected randomly from the outpatient department of an HIV clinic who were currently on for antiretroviral therapy (ART). Data on age, gender, form of contagion, antiretroviral therapy at the time of review, number of CD4 lymphocytes per milliliter, and viral load were collected. Oral cytologic investigation was carried out and then stained for histopathological examination. A total of 40 individuals were examined and the incidence of opportunistic infections was 66.7% in individuals with CD4 counts less than 200, 55.6% in individuals with CD4 counts of 200 to 499, and 40.0% in individuals with CD4 counts more than 500. The incidence of opportunistic infection was higher in individuals with low CD4 counts in spite of being on ART.

    Delayed graft function (DGF) is defined as the need for dialysis within the first week after renal transplantation, and slow graft function as persistence of serum creatinine concentration of at least 3 mg/dL on day 5 after the procedure. In the present study, we analyzed the incidence and risk factors for DGF at our center. This retrospective study included 106 patients who underwent renal transplantation between January 2000 and June 2008. Of these, 11 patients were excluded. Two of the remaining 95 patients received organs from living donors, and 93 received cadaver organs. Variables analyzed included donor age, cause of death, cause of chronic renal failure, recipient age, method and time of long-term renal replacement therapy, residual diuresis, panel of reactive antibodies (PRA), HLA mismatch, sex compatibility, cold and warm ischemia times, biopsy-confirmed episodes of acute rejection, urine output in the operating room and in the first 24 hours after the procedure, and intraoperative induction therapy. Data were analyzed using the chi(2) and Fisher exact tests and analysis of variance, and are given as mean (SD) and frequency. Variables associated with DGF at univariate analysis (P < .05) were divided between risk factors and predictors of DGF for inclusion in logistic regression models. The incidence of DGF was 32.6%; slow graft function, 16.8%; and immediate graft function, 50.5%. Cold ischemia time longer than 20 hours (P = .02) and donor age (P = .008) were directly associated with DGF. Twenty-four-hour urine output was a strong predictor of DGF. Patients with DGF demonstrated a 25% incidence of an episode of acute rejection before discharge from the hospital. No difference in DGF was observed for use of intraoperative induction therapy.

    This retrospective study used medical records from The Health Improvement Network (THIN) and Hospital Episode Statistics (HES) database to evaluate endometriosis (incidence, treatment and need for recurrent invasive procedures) in the general UK population. Women aged 12-54 years between January 2000 and December 2010, with a Read code for endometriosis, were identified in THIN. Cases were validated by manual review of free-text comments in medical records and responses to physician questionnaires. False-negative cases were identified among women with Read codes for hysterectomy or dysmenorrhea. Prescriptions of medical therapies for endometriosis were identified in THIN. Cases of single and recurrent invasive procedures were identified in women with medical records in both THIN and HES. Overall, 5087 women had a Read code for endometriosis, corresponding to an incidence of 1.02 (95% confidence interval [CI]: 0.99-1.05) per 1000 person-years. After case validation, the estimate was 1.46 (95% CI: 1.43-1.50) per 1000 person-years. Medical therapy was prescribed to 55.5% of women with endometriosis in the first year after diagnosis. In total, 48.3% of women received invasive treatment during the study period; approximately one-fifth of these women required further invasive treatment, mainly in the 3 years after the index procedure. Using Read codes as the only method to identify women with endometriosis underestimates incidence. Over half of women with recorded endometriosis are prescribed medical therapy in the first year after diagnosis. Women with diagnosed endometriosis are at risk of requiring recurrent invasive procedures.

    Full Text Available Introduction: Retinopathy of prematurity is a leading cause of blindness in children. This paper aims to evaluate the incidence, the rate of diode laser treatment and the six-month outcomes in all very low birth weight preterm infants from Hospital de Clínicas de Porto Alegre, Brazil, between October 2002 and October 2006, screened for the disease according to the Brazilian recommendations. Methods: A prospective cohort was conducted on 322 premature children with birth weight ≤1.500 grams or a gestational age at birth ≤32 weeks. All patients were examined by indirect binocular ophthalmoscopy with pupil’s dilation after the 6th week of life. The examination were repeated depending on the disease classification. Results: Retinopathy of prematurity occurred in 82 infants in an incidence rate of 25.47%. Threshold disease occurred in 18 of the patients (5.59%. All of them had the disease affecting posterior Zone II needing laser treatment under general anesthesia or sedation in the Neonatal Intensive Care Unity. Three of the treated children needed a second laser session. One patient of the re-treated group needed scleral buckling surgery with an equatorial silicon band after progression for stage 4 of ROP. One patient missed the opportunity for laser and the disease progressed to stage 5 of ROP and blindness. Conclusions: The incidence of retinopathy at our institution was similar to international results and also the percentage of threshold disease needing treatment. Laser photocoagulation was effective to stabilize the disease among 17 treated patients. One non-treated patient had evolution for blindness.

    Cleft lip and/or palate (CL/P) is the most common craniofacial anomaly. to determine the incidence of cleft lip and/or palate (CL/P) in patients born in the Hospital "Dr. Aurelio Valdivieso" in the city of Oaxaca between 2008 and 2010. A retrospective, cross-sectional study on all live births with non-syndromic orofacial cleft was realized. The variables included were CL/P presence, sex, and birth year. Clinical records of CL/P subjects were reviewed and clefts classified according to Kernahan and Stark. Tables were generated to present data. The total number of live births (LB) was 24,043 for the 2008 to 2010 period. In 2008, 9 cases (rate 1.01 per 1,000 LB) were identified: 7 boys and 2 girls. In 2009, there were 4 cases (rate 0.54 per 1,000 LB), 3 boys and 1 girl. In 2010, there were 11 cases (rate 1.42 per 1,000 LB), 7 boys and 4 girls. The total for the period 2008-2010 were 24 cases (rate 1.00 per 1,000 LB), 17 boys and 7 girls. Incidence rate was higher among male than among female. As for the distribution according to Kernahan and Stark classification, there were 4 boys and 3 girls in group "C", 10 boys and 4 girls in group "D", and only 3 boys in group "E"; not a single case in groups "A" and "B". The incidence for the period was 1.00 per 1,000 LB. The CL/P was more frequent in boys for each year included in the study.

    The prognosis from acute ischemic stroke (AIS) is worsened by poststroke medical complications. The incidence, risk factors, and outcomes of gastrointestinal bowel obstruction (GIBO) in AIS are not known. We queried the Nationwide Inpatient Sample (2002-2011) to identify all patients with a primary diagnosis of AIS and subsets with and without a secondary diagnosis of GIBO without hernia. Multivariable analysis was utilized to identify risk factors for GIBO in AIS patients and the association between GIBO, in-hospital complications, and outcomes. We identified 16,987 patients with GIBO (.43%) among 3,988,667 AIS hospitalizations and 4.2% of these patients underwent surgery. In multivariable analysis, patients with 75+ years of age were two times as likely to suffer GIBO compared to younger patients (P Stroke patients with pre-existing comorbidities (coagulopathy, cancer, blood loss anemia, and fluid/electrolyte disorder) were more likely to experience GIBO (all P risk factors identified in this study aim to encourage the monitoring of patients at highest risk for GIBO. The predominant form of stroke-related GIBO is nonmechanical obstruction, although the causative relationship remains unknown. Copyright © 2017 National Stroke Association. Published by Elsevier Inc.

    Patients with peripheral arterial disease (PAD) have lower functional capacity and worse clinical outcomes than age and gender matched patients. Few data exist on the relationship of PAD with functional and clinical outcomes in heart failure (HF) patients. We sought to compare HF patients with and without PAD for baseline functional capacity, response to exercise training, and clinical outcomes. HF-ACTION was a randomized controlled trial comparing usual care to structured exercise training plus usual care in HF patients with an ejection fraction ≤ 35% and NYHA class II – IV heart failure symptoms. Cardiopulmonary exercise (CPX) testing occurred at enrollment, 3 months, and 1 year. Clinical follow-up occurred up to 4 years. Of the 2331 HF-ACTION patients, 157 (6.8%) had PAD. At baseline, HF patients with PAD had a lower exercise duration (8.0 vs. 9.8 minutes, p<0.001), lower peak oxygen consumption (VO2) (12.5 vs. 14.6 mL/kg/min, p<0.001), and shorter six minute walking distance (306 vs. 371 meters, p<0.001) compared to HF patients without PAD. At three months, HF patients with PAD had less improvement on CPX testing [exercise duration (0.5 vs. 1.1 minutes; p=0.002) and peak VO2 (mean change; 0.1 vs. 0.6 mL/kg/min; p=0.04)] compared to HF patients without PAD. PAD was an independent predictor of all-cause death or hospitalization [hazard ratio (95% CI); 1.31 (1.06 – 1.62), p=0.011]. PAD patients with HF have depressed baseline exercise capacity and decreased response to exercise training. In conclusion, PAD is an independent predictor of all-cause death or hospitalization in HF patients. PMID:21565325

    Methicillin resistant coagulase-negative Staphylococci are resistant organisms causing infections associated with high morbidity and mortality. Methicillin resistant Staphylococcus epidermidis (MRSE), is especially important with respect to admitted patients with indwelling catheters and other installed invasive devices where these organisms are known to be found. As a result, such lifesaving measures may prove fatal from subsequent infection and sepsis by these pathogens. Therefore, to limit such conditions in patients, the spread of MRSE and related organisms in the hospitals have to be effectively controlled. This study was carried out to determine the frequency of methicillin resistant organisms among all isolated coagulase negative Staphylococci (CoNS) and to find effective antibiotics against these microorganisms. All samples sent to the lab were routinely processed according to standard microbiological procedures and the cultures yielding growth of CoNS were selected for the study. All samples containing CoNS collected over a 2 year-period, were included irrespective of patients' age and gender. The antibiogram of the organisms was recorded according to CLSI guidelines and the ratio of methicillin resistant organisms determined. From a total of 299 isolated coagulase negative Staphylococci (CoNS), 40.1% were methicillin resistant. A high proportion of these organisms (more than 50%) were resistant to cephalosporins, aminoglycosides and quinolones while only a small number were found to show resistance to linezolid, minocycline, chloramphenicol and rifampicin. There were no resistant organisms against vancomycin. A considerable amount of methicillin resistant organisms found among CoNS in our region. The above stated antibiotics would prove effective in limiting these infections. Clinicians should keep these facts in mind while treating their patients.

We studied the effects of nesiritide on renal function during hospitalization for acute decompensated heart failure and associated outcomes. A total of 7141 patients were randomized to receive either nesiritide or placebo and creatinine was recorded in 5702 patients at baseline, after infusion, discharge, peak/nadir levels until day 30. Worsening renal function was defined as an increase of serum creatinine >0.3 mg/dL and a change of ≥25%. Median (25(th)-75(th) percentile) baseline creatinine was 1.2 (1.0-1.6) mg/dL and median baseline blood urea nitrogen was 25 (18-39) mmol/L. Changes in both serum creatinine and blood urea nitrogen were similar in nesiritide-treated and placebo-treated patients (P=0.20 and P=0.41) from baseline to discharge. In a multivariable model, independent predictors of change from randomization to hospital discharge in serum creatinine were a lower baseline blood urea nitrogen, higher systolic blood pressure, lower diastolic blood pressure, previous weight gain, and lower baseline potassium (all Prenal function during hospitalization was similar in the nesiritide and placebo group (14.1% and 12.8%, respectively; odds ratio with nesiritide 1.12; confidence interval, 0.95-1.32; P=0.19) and was not associated with death alone and death or rehospitalization at 30 days. However, baseline, discharge, and change in creatinine were associated with death alone and death or rehospitalization for heart failure (all tests, Prenal function in patients with acute decompensated heart failure.

    Diabetes mellitus (DM) and atrial fibrillation (AF) are worldwide public health challenges and major causes of death and cardiovascular events. The association between DM and AF is controversial in literature and data on outcomes of individuals with both diseases have not been evaluated in population studies. We tested the hypothesis that DM is independently associated to AF hospitalization and assessed the risk of stroke and mortality in people with both conditions. We conducted a population-based cohort-study of DM patients and their corresponding controls identified in a administrative health database of the Lombardy Region. Both cohorts were followed for nine years. A multivariable Cox proportional-hazards-regression model was used to estimate the hazard ratio (HR) for first hospitalization for AF and for clinical outcomes. Out of 9,061,258 residents, 285,428 (3.14%) DM subjects were identified, mean age 65.8±15 years, 49% were women. The cumulative incidence of AF in DM was 10.4% vs. 7.4% in non-DM. DM was a risk factor for AF (HR 1.32, 95% CI 1.30-1.34; pOral anticoagulants were prescribed in 34.8% of DM patients with AF. DM associated with AF, presented the highest HR for stroke: 2.63; 95% CI 2.47-2.80 and for total death, HR 2.41; 95% CI 2.36-2.47. In this population study, DM was an independent risk factor for AF hospitalization. DM patients with AF had the highest risk of stroke and total mortality. Early identification of AF and a structured plan to optimize the comprehensive management of DM and AF patients is mandatory. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Prophylactic antibiotics are used to prevent postoperative infections after caesarean section. Studies have suggested that the timing of prophylaxis plays an important role. Over the years, the role of the anaesthesiologist in the administration of prophylactic antibiotics has become prominent. Therefore, there is an increasing need for anaesthesia providers to understand the rationale of antibiotic prophylaxis. We therefore sought to compare the effect of antibiotics prophylaxis within 1 hour before skin incision and after skin incision on the incidence of postoperative infections in patients undergoing caesarean section at Mulago Hospital. We conducted a single-blind randomised clinical trial conducted at Mulago Hospital evaluating 464 patients undergoing emergency caesarean section. Patients were randomly assigned a group number that allocated them to either arm of the study. They received the same prophylactic antibiotic according to their allotment, that is, either within 1 hour before skin incision or after skin incision as per current standards of practice in Mulago Hospital. They were followed up to detect infection up to 10 days postoperatively. The primary outcome was postoperative infection. The data collected were analysed with STATA version 12 using univariate and bivariate analysis. The risk of overall postoperative infection was significantly lower when prophylaxis was given within an hour before incision (RR O.77, 95% CI 0.62-0.97). We also found endometritis to be significantly reduced in the pre-incision group (RR 0.62; 95% CI 0.39-0.99; P value 0.036). Giving prophylactic antibiotics before skin incision reduces risk of postoperative infection, in particular of endometritis. Pan African Clinical Trial Registry PACTR201311000610495.

    Jaundice is the yellowish pigmentation of the skin, sclera, and mucous membranes resulting from bilirubin deposition. Children born to mothers with HIV are more likely to be born premature, with low birth weight, and to become septic-all risk factors for neonatal jaundice. Further, there has been a change in the prevention of mother-to-child transmission (PMTCT) of HIV guidelines from single-dose nevirapine to a six-week course, all of which theoretically put HIV-exposed newborns at greater risk of developing neonatal jaundice. We carried out a study to determine the incidence of severe and clinical neonatal jaundice in HIV-exposed neonates admitted to the Chatinkha Nursery (CN) neonatal unit at Queen Elizabeth Central Hospital (QECH) in Blantyre. Over a period of four weeks, the incidence among non-exposed neonates was also determined for comparison between the two groups of infants. Clinical jaundice was defined as transcutaneous bilirubin levels greater than 5 mg/dL and severe jaundice as bilirubin levels above the age-specific treatment threshold according the QECH guidelines. Case notes of babies admitted were retrieved and information on birth date, gestational age, birth weight, HIV status of mother, type of feeding, mode of delivery, VDRL status of mother, serum bilirubin, duration of stay in CN, and outcome were extracted. Of the 149 neonates who were recruited, 17 (11.4%) were HIV-exposed. One (5.88%) of the 17 HIV-exposed and 19 (14.4%) of 132 HIV-non-exposed infants developed severe jaundice requiring therapeutic intervention (p = 0.378). Eight (47%) of the HIV-exposed and 107 (81%) of the non-exposed neonates had clinical jaundice of bilirubin levels greater than 5 mg/dL (p < 0.001). The study showed a significant difference in the incidence of clinical jaundice between the HIV-exposed and HIV-non-exposed neonates. Contrary to our hypothesis, however, the incidence was greater in HIV-non-exposed than in HIV-exposed infants.

    radio systems. From the point of view Working Group 2 of the COST 296 Action, interest lies with effects associated

    with propagation via the ionosphere of signals within the HF band. Several aspects are covered in this paper:

    a The directions of arrival and times of flight of signals received over a path oriented along the trough have

    been examined and several types of propagation effects identified. Of particular note, combining the HF observations

    with satellite measurements has identified the presence of irregularities within the floor of the trough that

    result in propagation displaced from the great circle direction. An understanding of the propagation effects that

    result in deviations of the signal path from the great circle direction are of particular relevance to the operation

    of HF radiolocation systems.

    b Inclusion of the results from the above mentioned measurements into a propagation model of the northerly

    ionosphere (i.e. those regions of the ionosphere located poleward of, and including, the mid-latitude trough

    and the use of this model to predict the coverage expected from transmitters where the signals impinge on the

    This study was conducted to investigate the correlation between antibiotic consumption and the incidence of health-care-associated infections (HCAIs) caused by methicillin-resistant Staphylococcus aureus (MRSA) (HCAI-MRSA) and vancomycin-resistant enterococci (VREs) (HCAI-VREs) at a university hospital in Taiwan during the period from 2000 to 2010. Data on annual patient-days and annual consumption (defined daily dose/1000 patient-days) of glycopeptides (vancomycin and teicoplanin), linezolid, fusidic acid, tigecycline, and daptomycin were analyzed. Yearly aggregated data on the number of nonduplicate clinical MRSA and VRE isolates causing HCAI were collected. Overall, the consumption of teicoplanin and linezolid significantly increased during the study period. A significant decrease in the incidence of HCAI-MRSA and a significant increase in the incidence of HCAI-VRE were found during the study period. A significant correlation was found between the increased use of teicoplanin and linezolid and the decreased incidence of HCAI-MRSA. By contrast, positive correlations were found between the consumption of teicoplanin and tigecycline and the incidence of HCAI-VRE. This study identified various correlations between the consumption of antibiotics and the incidence of HCAI-MRSA and HCAI-VRE. Strict implementation of infection-control guidelines and reinforcement of administering appropriate antibiotic agents would be helpful in decreasing the incidence of MRSA and VRE in hospitals.

    The IN-HF Outcome registry enrolled 1855 patients admitted for acute heart failure and 3755 outpatients with chronic heart failure seen at 64 cardiology units of the Italian Network-Heart Failure. We assessed gender-related differences in clinical characteristics, management, and short- and long-term mortality and morbidity outcomes. Women were older, more often hypertensive and with a higher prevalence of heart failure with preserved systolic function. Aggressive management was less frequent in women who underwent less often diagnostic and therapeutic procedures. We found no gender-related differences in either acute or long-term mortality nor in hospital readmissions.

    Full Text Available Peculiar near range echoes observed in summer with the SuperDARN HF radar in Finland are presented. The echoes were detected at four frequencies of 9, 11, 13 and 15 MHz at slant ranges of 105–250 km for about 100 min. Interferometer measurements indicate that the echoes are returned from 80–100 km altitudes with elevation angles of 20°–60°. Echo power (< 16 dB, Doppler velocity (between –30 and + 30 ms-1 and spectral width (< 60 ms-1 fluctuate with periods of several to 20 min, perhaps due to short–period atmospheric gravity waves. When the HF radar detected the echoes, a vertical incidence MST radar, located at Esrange in Sweden (650 km north of the HF radar site, observed polar mesosphere summer echoes (PMSE at altitudes of 80–90 km. This fact suggests that the near range HF echoes are PMSE at HF band, although both radars did not probe a common volume. With increasing radar frequency, HF echo ranges are closer to the radar site and echo power becomes weaker. Possible mechanisms to explain these features are discussed.Key words.

    Full Text Available Assessing multiple traditional risk factors improves prediction for late-life diseases, including coronary heart disease (CHD. It appears that non-traditional risk factors can also predict risk. The objective was to investigate contributions of non-traditional risk factors to coronary heart disease risk using a deficit accumulation approach.Community-dwelling adults with no known history of CHD (n = 2195, mean age 46.9±18.7 years, 51.8% women participated in the 1995 Nova Scotia Health Survey. Three risk factor indices were constructed to quantify the proportion of deficits present in individuals: 1 a 17-item Non-Traditional Risk Factor Index (e.g. sinusitis, arthritis; 2 a 9-item Traditional Risk Factor Index (e.g. hypertension, diabetes; and 3 a frailty index (25 items combined from the other two index measures. Ten-year risks of CHD events (defined as CHD-related hospitalization and CHD-related mortality were evaluated.The Non-Traditional Risk Factor Index, made up of health deficits unrelated to CHD, was independently associated with incident CHD events over 10 years after controlling for age, sex, and the Traditional Risk Factor Index [adjusted {adj.} Hazard Ratio {HR} = 1.31; Confidence Interval {CI} 1.14-1.51]. When all health deficits, both those related and unrelated to CHD, were included in a frailty index the corresponding adjusted hazard ratio was 1.61; CI 1.40-1.85.Both traditional and non-traditional risk factor indices are independently associated with incident CHD events. CHD risk assessment may benefit from consideration of general health information as well as from traditional risk factors.

    Previous review of admissions from 2009-2011 in our institution found a 35.1% error rate in antiretroviral (ART) prescribing, with 55% of errors never corrected. Subsequently, our institution implemented a unified electronic medical record (EMR) and we developed a medication reconciliation process with an HIV pharmacist. We report the impact of the EMR on incidence of errors and of the pharmacist intervention on time to error correction. Prospective medical record review of HIV-infected patients hospitalized for >24 h between 9 March 2013 and 10 March 2014. An HIV pharmacist reconciled outpatient ART prescriptions with inpatient orders within 24 h of admission. Prescribing errors were classified and time to error correction recorded. Error rates and time to correction were compared to historical data using relative risks (RR) and logistic regression models. 43 medication errors were identified in 31/186 admissions (16.7%). The incidence of errors decreased significantly after EMR (RR 0.47, 95% CI 0.34, 0.67). Logistic regression adjusting for gender and race/ethnicity found that errors were 61% less likely to occur using the EMR (95% CI 40%, 75%; Perrors were corrected, 65% within 24 h and 81.4% within 48 h. Compared to historical data where only 31% of errors were corrected in errors were 9.4× more likely to be corrected within 24 h with HIV pharmacist intervention (Perror rate by more than 50% but despite this, ART errors remained common. HIV pharmacist intervention was key to timely error correction.

    Chronic renal failure is a global public health problem. In developed countries, this disease occurs mainly in the elderly, but in Africa it rather affects active young subjects. This disease need for expensive treatments in a low income country, because of its costs. Our aim is to describe the epidemiology of new cases of chronic renal failure in Madagascar. This is a retrospective, descriptive study of 239 patients with chronic renal failure over a 3 year period, starting from 1 January 2007 to 31 December 2009, in the Department of Internal Medicine and Nephrology at University Hospital of Antananarivo. The incidence was 8.51% among patients hospitalized in the Department. The average age of patients was 45.4 years with extremes of 16 and 82 years and a sex ratio 1,46. The main antecedent was arterial hypertension (59.8%). Chronic renal failure was terminal in 75.31% of the cases (n=180). The causes of chronic renal failure were dominated by chronic glomerulonephritis (40.1%), nephroangiosclerosis (35.5%). Hemodialysis was performed in 3 patients (1.26%), no patient was scheduled for a renal transplantation. Mortality rate in the Department was 28.87%. Chronic renal failure is a debilitating disease with a dreadful prognosis which affects young patients in Madagascar. Its treatment remains inaccessible to the majority of patients. The focus must be mainly on prevention, especially on early effective management of infections, arterial hypertension and diabetes to reduce its negative impacts on the community and public health. The project on renal transplantation: living donor, effective and less expensive treatment compared to hemodialysis could also be a good solution for these Malagasy young subjects.

    Paramedics are exposed to a number of factors that may have a direct or indirect impact on the risk of an accident at work. The aim of the study was to analyze the incidence of accidents at work among paramedics as well as to discuss risk factors and measures to prevent such cases. The data on accidents at work were obtained from unpublished internal hospital documentation. The results were subjected to statistical analysis. In the years 2001-2013 there were 40 events, including 6 collective accidents, in which 41 paramedics of the emergency department were injured. On average, around 3 accidents involving paramedics occurred each year. The accidents happened most frequently in the evening and at night and in the winter months (statistically insignificant relationship). Incorrect behavior of the paramedics was the most common cause of an accident (75.6%) and musculoskeletal injuries (75%) most frequently of upper and lower limbs (55%) were the most common effects of an accident. In none of the cases safety regulations were breached by employees or employer. Accidents among paramedics can be prevented by changing the interior design of and the medical equipment installation in the rear cabin of the ambulance, conducting regular training to upgrade the skills of paramedics and enriching their knowledge about health and safety in their widest meaning.

    Full Text Available Objective: The aim of this study was to evaluate the effectiveness of implementing a physical therapy guideline for patients undergoing upper abdominal surgery (UAS in reducing the incidence of atelectasis and length of hospital stay in the postoperative period. Materials and methods: A “before and after” study design with historical control was used. The “before” period included consecutive patients who underwent UAS before guideline implementation (intervention. The “after” period included consecutive patients after guideline implementation. Patients in the pre‐intervention period were submitted to a program of physical therapy in which the treatment planning was based on the individual experience of each professional. On the other hand, patients who were included in the post‐intervention period underwent a standardized program of physical therapy with a focus on the use of additional strategies (EPAP, incentive spirometry and early mobilization. Results: There was a significant increase in the use of incentive spirometry and positive expiratory airway pressure after guideline implementation. Moreover, it was observed that early ambulation occurred in all patients in the post‐intervention period. No patient who adhered totally to the guideline in the post‐intervention period developed atelectasis. Individuals in the post‐intervention period presented a shorter length of hospital stay (9.2 ± 4.1 days compared to patients in the pre‐intervention period (12.1 ± 8.3 days (p < 0.05. Conclusion: The implementation of a physical therapy guideline for patients undergoing UAS resulted in reduced incidence of atelectasis and reduction in length of hospital stay in the postoperative period.

    Although most patients in the PARADIGM-HF (Prospective Comparison of ARNI With ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure) trial had mild symptoms, there is a poor correlation between reported functional limitation and prognosis in heart failure. The aim of this study was to examine the spectrum of risk in PARADIGM-HF and the effect of LCZ696 across that spectrum. This study analyzed rates of the primary composite outcome of cardiovascular death or heart failure hospitalization, its components, and all-cause mortality using the MAGGIC (Meta-Analysis Global Group in Chronic Heart Failure) and EMPHASIS-HF (Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure) risk scores to categorize patients. The authors determined whether risk, on the basis of these scores, modified the treatment effect of LCZ696. The complete MAGGIC risk score was available for 8,375 of the 8,399 patients in PARADIGM-HF. The median MAGGIC score was 20 (IQR: 16 to 24). An increase of 1 point was associated with a 6% increased risk for the primary endpoint (p PARADIGM-HF patients had mild symptoms, many were at high risk for adverse outcomes and obtained a large absolute benefit from LCZ696, compared with enalapril, over a relatively short treatment period. LCZ696's benefit was consistent across the spectrum of risk.

    The technological advance has generated increasing demand for materials that can be used under high temperature, what includes intermetallic MR-Si-B (MR = refractory metal) alloys with multiphase structures, that can also be applied in oxide environments. Thus, this work had for objective the micro hardness study of the Hf-Si-B system alloys, heat treated at 1600 deg C, in the Hf rich region. Hf-Si-B alloys had been produced with blades of Hf (min. 99.8%), Si (min. 99.998%) and B (min. 99.5%), in the voltaic arc furnace and heat treated at 1600 deg C under argon atmosphere. The relationship of the phases had been previously identified by X-ray diffraction and contrast in backscattered electron imaging mode. The alloys had their hardness analyzed by method Vickers (micro hardness) with load of 0.05 kgf and 0.2 kgf and application time of 20 s. The results, obtained from the arithmetic mean of measurements for each alloy on the heterogeneous region, showed a mean hardness of 11.08 GPA, with small coefficient of variation of 3.8%. The borides HfB2 (19.34 GPa) e HfB - 11.76 GPa, showed the hardness higher than the silicides Hf2Si (8.57 GPa), Hf5Si3 (9.63 GPa), Hf3Si2 (11.66 GPa), Hf5Si4 (10.00 GPa), HfSi (10.02 GPa) e HfSi2 (8.61 GPa).

    Methods to identify patients at risk for incident HF would be welcome as such patients might benefit from earlier interventions. From a registry of 1251 patients referred for coronary and/or peripheral angiography, we sought to identify independent predictors of incident HF during follow-up and develop a clinical and biomarker strategy to predict this outcome. There were 991 patients free of prevalent HF at baseline. Cox proportional hazard models were developed to predict adjudicated diagnosis of incident HF. Model discrimination and reclassification were evaluated. At follow-up, 177 (18%) developed new-onset HF. Independent predictors of new-onset HF included five clinical variables (age, male sex, heart rate, history of atrial fibrillation/flutter, and history of hypertension) and two biomarkers (amino-terminal pro-B type natriuretic peptide and ST2). The c-statistic for the model without biomarkers was 0.69; including biomarkers increased the c-statistic to 0.76 (P time to incident HF compared with lower quintiles (log-rank P < 0.001). Following 100 bootstrap iterations, internal validation was confirmed with Harrell's c-statistic of 0.77. Use of angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and beta-blockers at enrollment was associated with substantial attenuation of predictive value of the risk score. Patients undergoing coronary/peripheral angiographic procedures are a population at high risk for incident HF. We describe an accurate clinical and biomarker strategy for predicting incident HF and possibly intervening in such patients (NCT00842868). © 2018 The Authors.

    1982-01-01

    There were four basic questions addressed in this report that relate to the HF interaction in the environment. As to whether HF hydrates in the vapor phase and what the rate of that hydration is, there seems ample evidence that HF hydrates readily in the vapor phase and the rate of that hydration is very fast, i.e., dHF/dt greater than or equal to 25 torr sec -1 . Concerning under what conditions condensation of the hydrate will occur and whether a third body is required for condensation, it was found that HF does effect the dew point or condensation of water and data was presented indicating the extent of that effect. It was also determined that condensation will occur without a third body present. Thus, in attempting to model an HF release for the Safety Analysis Report the hydration of HF and the subsequent heat released may be treated as occurring instantaneously; but the ultimate disposition of the HF will be strongly dependent upon the environmental conditions at the time of the release

    This study aims to retrospectively analyze the incidence and pattern of cranio-maxillofacial injuries in the developing world in a hope to emphasize on authorities the need of improvising infrastructural facilities, medical and other. Hospital medical records with available radiographs of 6,872 patients treated for cranio-maxillofacial injuries at major trauma centres in Pune, India over a 22 year period (from July 1989 to June 2010) were reviewed. Relevant data pertaining to patients' age, sex, cause of injury, sites of injury, associated injuries, anaesthesia, various treatment modalities and complications were recorded and analyzed statistically. A total of 6,872 patients sustained maxillofacial injuries of which 5,936 (86.4 %) were caused by road traffic accidents (RTA), followed by fall in 608 cases. Distribution pattern of sex revealed male predominance (M:F-2.5:1) and the third decade age group (2,416) sustained maximum cranio-maxillofacial injuries. Of 12,503 cranio-maxillofacial sites involved, mandible (6,456) predominated, while there was middle third involvement in 5,024 cases. Most of the patients (4,856) were treated with open reduction and internal fixation without maxillo-mandibular fixation and complications were noted in 320 patients. In comparison to similar recent studies reported in the literature, our findings show that RTA remains the most common cause of cranio-maxillofacial injuries with male preponderance. Also RTA remains the major preventable etiological factor of cranio-maxillofacial injuries, which should prompt authorities to take "Herculean effort" to implement rules and educate people.

    Aspiration of colonized oropharyngeal secretions is a major factor in the pathogenesis of ventilator-associated pneumonia (VAP). A tapered-cuff endotracheal tube (ETT) has been demonstrated to reduce aspiration around the cuff. Whether these properties are efficacious in reducing VAP is not known. This 2-period, investigator-initiated observational study was designed to assess the efficacy of a tapered-cuff ETT to reduce the VAP rate. All intubated, mechanically ventilated patients over the age of 18 were included. During the baseline period a standard, barrel-shaped-cuff ETT (Mallinckrodt Hi-Lo) was used. All ETTs throughout the hospital were then replaced with a tapered-cuff ETT (TaperGuard). The primary outcome variable was the incidence of VAP per 1,000 ventilator days. We included 2,849 subjects, encompassing 15,250 ventilator days. The mean ± SD monthly VAP rate was 3.29 ± 1.79/1,000 ventilator days in the standard-cuff group and 2.77 ± 2.00/1,000 ventilator days in the tapered-cuff group (P = .65). While adherence to the VAP prevention bundle was high throughout the study, bundle adherence was significantly higher during the standard-cuff period (96.5 ± 2.7%) than in the tapered-cuff period (90.3 ± 3.5%, P = .01). In the setting of a VAP rate very near the average of ICUs in the United States, and where there was high adherence to a VAP prevention bundle, the use of a tapered-cuff ETT was not associated with a reduction in the VAP rate.

    Full Text Available Abstract Background Heart failure(HF and atrial fibrillation(AF frequently coexist in the same patient and are associated with increased mortality and frequent hospitalizations. As the concomitance of AF and HF is often associated with a poor prognosis, the prompt treatment of AF in HF patients may significantly improve outcome. Methods/design Recent implantable cardiac resynchronization (CRT devices allow electrical therapies to treat AF automatically. TRADE-HF (trial registration: NCT00345592; http://www.clinicaltrials.gov is a prospective, randomized, double arm study aimed at demonstrating the efficacy of an automatic, device-based therapy for treatment of atrial tachycardia and fibrillation(AT/AF in patients indicated for CRT. The study compares automatic electrical therapy to a traditional more usual treatment of AT/AF: the goal is to demonstrate a reduction in a combined endpoint of unplanned hospitalizations for cardiac reasons, death from cardiovascular causes or permanent AF when using automatic atrial therapy as compared to the traditional approach involving hospitalization for symptoms and in-hospital treatment of AT/AF. Discussion CRT pacemaker with the additional ability to convert AF as well as ventricular arrhythmias may play a simultaneous role in rhythm control and HF treatment. The value of the systematic implantation of CRT ICDs with the capacity to deliver atrial therapy in HF patients at risk of AF has not yet been explored. The TRADE-HF study will assess in CRT patients whether a strategy based on automatic management of atrial arrhythmias might be a valuable option to reduce the number of hospital admission and to reduce the progression the arrhythmia to a permanent form.

    Solid solutions of ZrO2 and HfO2 are potential electrolyte materials for intermediate-temperature SOFC because both are oxygen-ion conductors. The main challenge for these compounds is to reduce the relatively high value of the activation energies vacancies diffusion, which is influenced by several factors. In this work the thermal evolution of CaO-HfO{sub 2} materials have been investigated. (CaO)y-Hf(1-y)O(2-y) (y = 0.06, 0.14 y 0.2) coatings and powders were synthesized by chemical solution deposition (CSD). Films were deposited onto alumina substrates by Dip Coating technique, the burning of organic waste was carried out at 500 deg. C under normal atmosphere and then the films were thermally treated at intervals of temperature rising to a maximum temperature of 1250 deg. C. By means Glazing Incidence X-ray Diffraction (rho-2theta configuration) the phases were studied in the annealed films. On the other hand, the thermal evolution and crystallization process of powders were analyzed in-situ by HT-XRD. The phenomena crystallization occurred in films and powders were analyzed. The activation energies of diffusion of oxygen vacancies of HfO2-14 mole% CaO and HfO2-20 mole% CaO films were measured from the thermal evolution of the relaxation constant measured by Perturbed Angular Correlation Technique.

  8. HF Radio Wave Production of Artificial Ionospheres

    Science.gov (United States)

    Carlson, Herbert

    In 1993 it was predicted that artificial ionospheres would be produced by high power HF radio waves, once HF transmitters approached a GWatt ERP. When that threshold was very recently achieved, such production was indeed detected and published at two high latitude high power HF facilities. Here we review: the first-principles logic behind that prediction, which aspects of such production are critically dependent on magnetic latitude, and which aspects of such production depend only on physical parameters independent of latitude. These distinctions follow directly from decomposition of the problem of ionization production into its components of: radio-wave propagation, wave-particle interactions, electron transport, and quantitative elastic/inelastic cross-sections. We outline this analysis to show that, within the context of early observations, the production of ionization is inevitable, and only a question of competing instability thresholds, and scale of ionization production. This illustrates complimentary aeronomy and plasma physics to advance understanding of both.

    Heart failure (HF) hospitalization rates are decreasing in western Europe, but little is known about trends in central and east European countries. We analysed the Slovenian national hospitalization database to determine the burden of HF hospitalization. The Slovenian National Hospital Discharge Registry was searched for HF hospitalizations between 2004 and 2012 in patients aged ≥20 years. A total of 55 531 main HF hospitalizations (43 636 first HF hospitalizations) in 34 406 patients (median age 78 years, 55% female) were recorded. The most common co-morbidities were arterial hypertension (54.3%), atrial fibrillation (40.6%), diabetes mellitus (24.5%), and ischaemic heart disease (21.9%). The number of age-standardized main and first HF hospitalizations per 100 000 population decreased from 249 to 232 (7.1%, P = 0.002) and from 467 to 435 (6.8%, P = 0.074), respectively. Crude main and first HF hospitalization rates increased from 249 to 298 (19.8%, P Slovenia, standardized HF hospitalization rates have decreased but the crude HF hospitalization burden has increased.

  10. Lu-Hf constraints on the evolution of lunar basalts

    Fujimaki, H.; Tatsumoto, M.

    1984-01-01

    Very low Ti basalts andd green glass samples from the moon show high Lu/Hf ratios and low Hf concentrations. Low-Ti lunar basalts show high and variable Lu/Hf ratios and higher Hf concentrations, whereas high-Ti lunar basalts show low Lu/Hf ratios and high Hf concentrations. KREEP basalts have constant Lu/Hf ratios and high but variable Hf concentrations. Using the Lu-Hf behavior as a constraint, we propose a model for the mare basalts evolution. This constraint requires extensive crystallization of the primary lunar magma ocean prior to formation of the lunar mare basalt sources and the KREEP basalts. Mare basalts are produced by the melting of the cumulate rocks, and KREEP basalts represent the residual liquid of the magma ocean

    Unintentional injury leads all other causes of death for those 1 to 45 years old. The expense of medical care for injured people is estimated to exceed $406 billion annually. Given this burden on the population, the Centers for Disease Control and Prevention consistently refers to injury prevention as a national priority. We postulated that exposure to crime and the density of alcohol outlets in one's neighborhood will be positively associated with the incidence of hospitalization for and mortality from traumatic injuries, independent of other neighborhood characteristics. We conducted a cross-sectional study with ecological and individual analyses. Patient-level data for traumatic injury, injury severity, and hospital mortality due to traumatic injury in 2010 were gathered from the Dallas-Fort Worth Hospital Council Foundation. Each case of traumatic injury or death was geospatially linked with neighborhood of origin information from the 2010 U.S. Census within Dallas County, Texas. This information was subsequently linked with crime data gathered from 20 local police departments and the Texas Alcoholic Beverage Commission alcohol outlet dataset. The crime data are the Part One crimes reported to the Federal Bureau of Investigation. The proportion of persons 65 years old or older was the strongest predictor of the incidence of hospitalization for traumatic injury (b = 12.64, 95% confidence interval (CI) 8.73 to 16.55). In turn, the incidence of traumatic injury most strongly predicted the severity of traumatic injury (b = 0.008, 95% CI 0.0003 - 0.0012). The tract-level unemployment rate was associated with a 5% increase in the odds of hospital mortality among hospitalized trauma patients. Several neighborhood characteristics were associated with the incidence, severity, and hospital mortality from traumatic injury. However, crime rates and alcohol outlet density carried no such association. Prevention efforts should focus on neighborhood characteristics such

    Heart failure (HF) is the main cause of death in adult congenital heart disease (ACHD). We aimed to characterize HF-related hospitalization of patients with ACHD, and to determine HF risk factors and prognosis in this population. We prospectively included 471 patients with ACHD admitted to our unit over 24 months. Clinical and biological data and HF management were recorded. Major cardiovascular events were recorded for ACHD with HF. HF was the main reason for hospitalization in 13% of cases (76/583 hospitalizations). Patients with HF were significantly older (median age 44±14 years vs. 37±15 years; Pcongenital heart disease (P=0.04). In the multivariable analysis, pulmonary arterial hypertension (odds ratio [OR] 6.2, 95% confidence interval [CI] 3.5-10.7), history of HF (OR 9.8, 95% CI 5.7-16.8) and history of atrial arrhythmia (OR 3.6, 95% CI 2.2-5.9) were significant risk factors for HF-related admissions (Pheart transplantation during the median follow-up of 18 months (95% CI 14-20 months). The risk of cardiovascular events was 19-fold higher after HF-related hospitalization. HF is emerging as a leading cause of morbidity and mortality in the ACHD population. Earlier diagnosis and more active management are required to improve outcomes of HF in ACHD. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    There is growing evidence that health systems in developed countries are poorly prepared to deal with major incidents. This study aimed to determine the skills required for successful major incident response, the factors that contribute to a successful major incident exercise, and whether there is a role for using novel simulation training (virtual worlds) in preparing for major incidents. This was a qualitative semi-structured interview study. Fourteen health care staff with experience of major incident planning and training in the United Kingdom were recruited. Interviews were content-analyzed to identify emergent themes. The aims and benefits of current exercises were categorized into three major themes: Organizational, Interpersonal, and Cognitive. Participants felt that the main objective of current exercises is to see how a major incident plan is implemented, rather than training individual staff. Communications was the most frequently commented-on area requiring improvement. Participants felt that lack of constructive feedback reduced the effectiveness of the exercises. All participants commented that virtual worlds technology could be successfully utilized for training. The creation of an immersive environment, increased training opportunity, and improved participant feedback were thought to be amongst the greatest benefits. There are clear deficiencies with current major incident preparation. Utilizing virtual worlds technology as an adjunct to existing exercises could improve training and response in the future.

    The Research Center System Safety of the Berlin University of Technology conducted a research project on the analysis of Human Factors (HF) aspects in incident reported by German Nuclear Power Plants. Based on psychological theories and empirical studies a classification scheme was developed which permits the identification of human involvement in incidents. The classification scheme was applied in an epidemiological study to a selection of more than 600 HF - relevant incidents. The results allow insights into HF related problem areas. An additional study proved that the application of the classification scheme produces results which are reliable and independent from raters. (author). 13 refs, 1 fig

    Heart failure with preserved ejection fraction (HFpEF) is characterized by elevated left atrial pressure during rest and/or exercise. The Reduce LAP-HF (Reduce Elevated Left Atrial Pressure in Patients With Heart Failure) trial will evaluate the safety and performance of the Interatrial Shunt Device (IASD) System II, designed to directly reduce elevated left atrial pressure, in patients with HFpEF. The Reduce LAP-HF Trial is a prospective, nonrandomized, open-label trial to evaluate a novel device that creates a small permanent shunt at the level of the atria. A minimum of 60 patients with ejection fraction ≥40% and New York Heart Association functional class III or IV heart failure with a pulmonary capillary wedge pressure (PCWP) ≥15 mm Hg at rest or ≥25 mm Hg during supine bike exercise will be implanted with an IASD System II, and followed for 6 months to assess the primary and secondary end points. Safety and standard clinical follow-up will continue through 3 years after implantation. Primary outcome measures for safety are periprocedural and 6-month major adverse cardiac and cerebrovascular events (MACCE) and systemic embolic events (excluding pulmonary thromboembolism). MACCE include death, stroke, myocardial infarction, or requirement of implant removal. Primary outcome measures for device performance include success of device implantation, reduction of PCWP at rest and during exercise, and demonstration of left-to-right flow through the device. Key secondary end points include exercise tolerance, quality of life, and the incidence of heart failure hospitalization. Reduce LAP-HF is the first trial intended to lower left atrial pressure in HFpEF by means of creating a permanent shunt through the atrial septum with the use of a device. Although the trial is primarily designed to study safety and device performance, we also test the pathophysiologic hypothesis that reduction of left atrial pressure will improve symptoms and quality of life in patients

    Objectives The exact form of the association between systolic blood pressure (SBP) and heart failure (HF) risk in the elderly remains incompletely defined, especially in individuals not receiving antihypertensive medications. Our aim was to examine the association between SBP and HF risk in the elderly. Design Competing-risks proportional hazards modeling of incident HF risk, utilizing 10-year follow-up data from two NIH-sponsored cohort studies; the Cardiovascular Health Study (inception: 1989-90 and 1992-93) and the Health ABC Study (inception: 1997-98). Setting Community-based cohorts. Participants 4408 participants (age, 72.8 [4.9] years; 53.1% women, 81.7% white; 18.3% black) without prevalent HF and not receiving antihypertensive medications at baseline. Main outcome measures Incident HF, defined as first adjudicated hospitalisation for HF. Results Over 10 years, 493 (11.1%) participants developed HF. Prehypertension (120-139 mmHg), stage 1 (140-159 mmHg), and stage 2 (≥160 mmHg) hypertension were associated with escalating HF risk; hazard ratios vs. optimal SBP (<120 mmHg) in competing-risks models controlling for clinical characteristics were 1.63 (95% CI, 1.23-2.16; P=0.001), 2.21 (95% CI, 1.65-2.96; P<0.001), and 2.60 (95% CI, 1.85-364; P<0.001), respectively. Overall 255 of 493 (51.7%) HF events occurred in participants with SBP <140 mm Hg at baseline. Increasing SBP was associated with higher HF risk in women than men; no race-SBP interaction was observed. In analyses with continuous SBP, HF risk had a continuous positive association with SBP to levels as low as 113 mmHg in men and 112 mmHg in women. Conclusions There is a continuous positive association between SBP and HF risk in the elderly for levels of SBP as low as <115 mmHg; over half of incident HF events occur in individuals with SBP <140 mmHg.

    Although case series suggest a higher burden of cardiovascular risk factors in patients with systemic lupus erythematosus (SLE) compared with the general population, the association between SLE and heart failure (HF) remains undefined. We sought to investigate the incidence and risk of HF in patients with SLE. In April 2016, we performed a retrospective cohort analysis using the Explorys platform, which provides aggregated electronic medical record data from 26 major integrated healthcare systems across the USA from 1999 to present. Demographic and regression analyses were performed to assess the impact of SLE on HF incidence. Among 45 284 540 individuals in the database, we identified 95 400 (0.21%) with SLE and 98 900 (0.22%) with a new diagnosis of HF between May 2015 and April 2016. HF incidence was markedly higher in the SLE group compared with controls (0.97% vs 0.22%, relative risk (RR): 4.6 (95% CI 4.3 to 4.9)), as were other cardiovascular risk factors. In regression analysis, SLE was an independent predictor of HF (adjusted OR: 3.17 (2.63 to 3.83), prisk but decreasing RR with advancing age in both sexes. Renal involvement in SLE correlated with earlier and higher incidence of HF. The findings of this study suggest that patients with SLE have significantly higher risk of developing HF and a worse cardiovascular risk profile compared with the general population. These results need to be confirmed by prospective studies. Published by the BMJ Publishing Group Limited.

    As an important data for a fusion reactor there are not any experimental results for the cross section of the 179 Hf(n,2n) 178m2 Hf reaction. So the cross section was measured in this work at neutron energy of 14 MeV. Meanwhile, we also gave the data for the cross section of the 180 Hf(n,2n) 179m2 Hf reaction.

    Highlights: • Hafnium oxide growth on Si(100) by atomic layer deposition was simulated. • The interface structure was considered as silicate and silicide. • The interface was studied employing DFT. • TDMA-Hf precursor show better interface stability. - Abstract: The final structure of HfO 2 films grown by atomic layer deposition (ALD) after reaction with OH − ions has been analyzed by DFT (density functional theory). The interaction of the precursors: HfCl 4 (hafnium tetrachloride), HfI 4 (hafnium tetraiodide), TEMA-Hf (tetrakis-ethylmethylamino hafnium), and TDMA-Hf (tetrakis-dimethylamino hafnium) with HO–H was studied employing the B3LYP (Becke 3-parameter, Lee–Yang–Parr) hybrid functional and the PBE (Perdew–Burke–Ernzerhof) generalized gradient functional. The structural evolution at the Si(100) surface has been analyzed by LDA (local density approximation). The structural parameters: bond length and bond angle, and the vibrational parameters for the optimized structures are also reported. The presence of hafnium silicate at the interface was detected. The infrared spectra and structural parameters obtained in this work agree with previously reported experimental results.

    Cervical spondylosis is well accepted as a common degenerative change in the cervical spine. Compelling evidence has shown that the incidence of cervical spondylosis increases with age. However, the relationship between age and the incidence of cervical spondylosis remains obscure. It is essential to note the relationship between age and the incidence of cervical spondylosis through more and more clinical data. In the case-controlled study reported here, retrospective clinical analysis of 1,276 cases of cervical spondylosis has been conducted. We analyzed the general clinical data, the relationship between age and the incidence of cervical spondylosis, and the relationship between age-related risk factors and the incidence of cervical spondylosis. A chi-square test was used to analyze the associations between different variables. Statistical significance was defined as a P-value of less than 0.05. The imaging examination demonstrated the most prominent characteristic features of cervical spondylosis: bulge or herniation at C3-C4, C4-C5, and C5-C6. The incidence of cervical spondylosis increased with aging before age 50 years and decreased with aging after age 50 years, especially in the elderly after 60 years old. The occurrence rate of bulge or herniation at C3-C4, C4-C5, C5-C6, and C6-C7 increased with aging before age 50 years and decreased with aging after age 50 years, especially after 60 years. Moreover, the incidence of hyperosteogeny and spinal stenosis increased with aging before age 60 years and decreased with aging after age 60 years, although there was no obvious change in calcification. The age-related risk factors, such as hypertension, hyperlipidemia, diabetes, cerebral infarct, cardiovascular diseases, smoking, and drinking, have no relationship with the incidence of cervical spondylosis. A decreasing proportion of cervical spondylosis with aging occurs in the elderly, while the proportion of cervical spondylosis increases with aging in the young

  9. Self-diffusion of Er and Hf inpure and HfO2-doped polycrystalline Er2O3

    Using a tracer technique, self-diffusion of Er and Hf was measured over the approximate temperature interval of 1600 to 1970 0 C in pure and HfO 2 -doped polycryatalline Er 2 O 3 . Up to about 10 m/o HfO 2 dopant level, the Er self-diffusion coefficients followed a relationship based on cation vacancies. Above 10 m/o HfO 2 , deviation from this relationship occurred, apparently due to clustering of cation vacancies and oxygen interstitials around the dopant hafnia ion. The activation energy for the self-diffusion of Er in pure Er 2 O 3 was 82.2 Kcal/mole and increased with the HfO 2 dopant level present. Self-diffusion of Hf was measured in pure Er 2 O 3 having two impurity levels, and a separation of the grain boundary. The volume diffusion of Hf showed both extrinsic and intrinsic behavior with the transition temperature increasing with the impurity level present in Er 2 O 3 . The activation energy for Hf volume diffusion in the intrinsic region was high, i.e. 235 -+ 9.5 Kcal/mole. The grain boundary diffusion was apparently extrinsic over the entire temperature interval Very low Hf self diffusion rates were found in both pure and HfO 2 doped Er 2 O 3 compositions. Despite a clustering effect, the HfO 2 dopant increased the Hf volume diffusion coefficients

    Hafnium ion forms a strong complex with nitrilotriacetic acid (NTA). But there is a controversy about the nature of the complex on whether it is a 1:1 or a 1:2 complex. We have carried out an electrophoresis experiment and supplemented data to establish the nature of the complex. Our data indicates that it is a 1:2 complex i.e. [Hf(NTA) 2 ] 2- in which the coordination number 8 has been satisfied for hafnium. (author)

    Aims This report describes the baseline characteristics of patients in the Reduction of Events with Darbepoetin alfa in Heart Failure trial (RED-HF) which is testing the hypothesis that anaemia correction with darbepoetin alfa will reduce the composite endpoint of death from any cause or hospital admission for worsening heart failure, and improve other outcomes. Methods and results Key demographic, clinical, and laboratory findings, along with baseline treatment, are reported and compared with those of patients in other recent clinical trials in heart failure. Compared with other recent trials, RED-HF enrolled more elderly [mean age 70 (SD 11.4) years], female (41%), and black (9%) patients. RED-HF patients more often had diabetes (46%) and renal impairment (72% had an estimated glomerular filtration rate <60 mL/min/1.73 m2). Patients in RED-HF had heart failure of longer duration [5.3 (5.4) years], worse NYHA class (35% II, 63% III, and 2% IV), and more signs of congestion. Mean EF was 30% (6.8%). RED-HF patients were well treated at randomization, and pharmacological therapy at baseline was broadly similar to that of other recent trials, taking account of study-specific inclusion/exclusion criteria. Median (interquartile range) haemoglobin at baseline was 112 (106–117) g/L. Conclusion The anaemic patients enrolled in RED-HF were older, moderately to markedly symptomatic, and had extensive co-morbidity. PMID:23329651

    This paper reports NMR measurements of the magnetic dipole moments of two high-K isomers, the 37/2-, 51.4 m, 2740 keV state in Hf177 and the 8-, 5.5 h, 1142 keV state in Hf180 by the method of on-line nuclear orientation. Also included are results on the angular distributions of γ transitions in the decay of the Hf177 isotope. These yield high precision E2/M1 multipole mixing ratios for transitions in bands built on the 23/2+, 1.1 s, isomer at 1315 keV and on the 9/2+, 0.663 ns, isomer at 321 keV. The new results are discussed in the light of the recently reported finding of systematic dependence of the behavior of the gR parameter upon the quasiproton and quasineutron make up of high-K isomeric states in this region.

    There are increasing reports of multidrug-resistant gram-negative bacilli in nursing homes and acute care hospitals. We performed a point prevalence survey to detect fecal carriage of gram-negative bacteria carrying carbapenem resistance genes or which were otherwise resistant to carbapenem antibiotics among 500 consecutive admissions from local nursing homes to 2 hospitals in Providence, Rhode Island. We performed a case-control study to identify risk factors associated with carriage of carbapenem-resistant Enterobacteriaceae (CRE). There were 404 patients with 500 hospital admissions during which they had rectal swab samples cultured. Fecal carriage of any carbapenem-resistant or carbapenemase- producing gram-negative bacteria was found in 23 (4.6%) of the 500 hospital admissions, including 7 CRE (1.4%), 2 (0.4%) of which were Klebsiella pneumoniae carbapenemase (ie, blaKPC) producing (CPE) Citrobacter freundii, 1 of which was carbapenem susceptible by standard testing methods. Use of a gastrostomy tube was associated with CRE carriage (P = .04). We demonstrated fecal carriage of carbapenem-resistant or carbapenemase-producing gram-negative bacteria in 4.6% of nursing home patients admitted to 2 acute care hospitals, but only 0.4% of such admissions were patients with fecal carriage of CPE. Use of gastrostomy tubes was associated with fecal carriage of gram-negative bacteria with detectable carbapenem resistance. CRE fecal carriage is uncommon in our hospital admissions from nursing homes. Copyright © 2016 Association for Professionals in Infection Control and Epidemiology, Inc. Published by Elsevier Inc.

    The AVOID-HF (Aquapheresis versus Intravenous Diuretics and Hospitalization for Heart Failure) trial tested the hypothesis that patients hospitalized for HF treated with adjustable ultrafiltration (AUF) would have a longer time to first HF event within 90 days after hospital discharge than those receiving adjustable intravenous loop diuretics (ALD). Congestion in hospitalized heart failure (HF) patients portends unfavorable outcomes. The AVOID-HF trial, designed as a multicenter, 1-to-1 randomized study of 810 hospitalized HF patients, was terminated unilaterally and prematurely by the sponsor (Baxter Healthcare, Deerfield, Illinois) after enrollment of 224 patients (27.5%). Aquadex FlexFlow System (Baxter Healthcare) was used for AUF. A Clinical Events Committee, blinded to the randomized treatment, adjudicated whether 90-day events were due to HF. A total of 110 patients were randomized to AUF and 114 to ALD. Baseline characteristics were similar. Estimated days to first HF event for the AUF and ALD group were, respectively, 62 and 34 (p = 0.106). At 30 days, compared with the ALD group, the AUF group had fewer HF and cardiovascular events. Renal function changes were similar. More AUF patients experienced an adverse effect of special interest (p = 0.018) and a serious study product-related adverse event (p = 0.026). The 90-day mortality was similar. Compared with the ALD group, the AUF group trended toward a longer time to first HF event within 90 days and fewer HF and cardiovascular events. More patients in the AUF group experienced special interest or serious product-related adverse event. Due to the trial's untimely termination, additional AUF investigation is warranted.

    Allan Hills (ALH) 84001 is an orthopyroxenite that is unique among the Martian meteorites in having the oldest inferred crystallization age (approx..4.5 to 4.0 Gyr) [e.g., 1-6 and references therein 7]. Its ancient origin makes this stone a critical constraint on early history of Mars, in particular the evolution of different planetary crust and mantle reservoirs. However, because there is significant variability in reported crystallization ages, determination of initial isotope compositions is imprecise making assessment of planetary reservoirs difficult. Here we report a new Lu-Hf mineral isochron age, initial Hf-176/Hf-177 isotope composition, and inferred Martian mantle source compositions for ALH84001 that place constraints on longlived source reservoirs for the enriched shergottite suite of Martian meteorites including Shergotty, Zagami, NWA4468, NWA856, RBT04262, LAR06319, and Los Angeles. Sm-Nd isotope analyses are under way for the same mineral aliquots analyzed for Lu-Hf. The Lu-Hf system was utilized because Lu and Hf are both lithophile and refractory and are not easily redistributed during short-lived thermal pulses associated with shock metamorphism. Moreover, chromite has relatively modest Hf concentrations with very low Lu/Hf ratios [9] yielding tight constraints on initial Hf-176/Hf-177 isotope compositions

    To explore the quality/comprehensiveness of nursing documentation of pressure ulcers and to investigate the relationship between the nursing documentation and the incidence of pressure ulcers in four intensive care units. Pressure ulcer prevention requires consistent assessments and documentation to decrease pressure ulcer incidence. Currently, most research is focused on devices to prevent pressure ulcers. Studies have rarely considered the relationship among pressure ulcer risk factors, incidence and nursing documentation. Thus, a study to investigate this relationship is needed to fill this information gap. A retrospective, comparative, descriptive, correlational study. A convenience sample of 196 intensive care units patients at the selected medical centre comprised the study sample. All medical records of patients admitted to intensive care units between the time periods of September 1, 2011 through September 30, 2012 were audited. Data used in the analysis included 98 pressure ulcer patients and 98 non-pressure ulcer patients. The quality and comprehensiveness of pressure ulcer documentation were measured by the modified European Pressure Ulcer Advisory Panel Pressure Ulcers Assessment Instrument and the Comprehensiveness in Nursing Documentation instrument. The correlations between quality/comprehensiveness of pressure ulcer documentation and incidence of pressure ulcers were not statistically significant. Patients with pressure ulcers had longer length of stay than patients without pressure ulcers stay. There were no statistically significant differences in quality/comprehensiveness scores of pressure ulcer documentation between dayshift and nightshift. This study revealed a lack of quality/comprehensiveness in nursing documentation of pressure ulcers. This study demonstrates that staff nurses often perform poorly on documenting pressure ulcer appearance, staging and treatment. Moreover, nursing documentation of pressure ulcers does not provide a complete

    Full Text Available Background: Ventilator-associated pneumonia (VAP is a common side effect in patients who receive intravenous sedation infusion. In routine care, after starting sedation infusion for patients who receive mechanical ventilation, interruption of sedation starts without protocol. This study aimed to evaluate the effect of daily sedation vacation protocol on the incidence of VAP in mechanically ventilated patients. Materials and Methods: In this clinical trial study, 80 patients with intravenous sedation infusion were selected and randomly allocated to intervention and control groups. In the intervention group, daily sedation vacation protocol and in the control group, routine sedation vacation was followed. Modified clinical pulmonary infection score questionnaire was completed before intervention and on the third, fourth, and fifth days after intervention. Data were analyzed by using repeated measures analysis of variance (ANOVA, Chi-square, and independent t-test. Results: The results of this study showed that the incidence rate of VAP in the intervention and control groups was 0% versus 15% on the third day of intervention, 12.5% versus 50% on the fourth day, and 27.5% versus 55.3% on the fifth day of intervention in the intervention and control groups, respectively. The incidence of VAP in the intervention group was significantly lower than in the control group (P < 0.05. Conclusions: The results of this study showed that in patients with intravenous sedation, infusion of a daily sedation vacation protocol may reduce the incidence of VAP. Therefore, in order to prevent VAP, nurses are recommended to use this daily sedation vacation protocol.

    AIMS: Approximately 20% of deaths from adverse events are related to medication incidents, costing the NHS an additional £500 million annually. Less than 5% of adverse events are reported. This study aims to assess the reporting rate of medication incidents in NHS facilities in the north east of Scotland, and to describe the types and outcomes of reported incidents among different services. Furthermore, we wished to quantify the proportion of reported incidents according to the reporters\\' profession. METHODS: A retrospective description was made of medication incidents reported to an online reporting system (DATIX) over a 46-month-period (July 2005 to April 2009). Reports originated from acute and community hospitals, mental health, and primary care facilities. RESULTS: Over the study period there were 2,666 incidents reported with a mean monthly reporting rate of 78.2\\/month (SD±16.9). 6.1% of all incidents resulted in harm, with insulin being the most commonly implicated medication. Nearly three-quarters (74.2%, n=1,978) of total incidents originated from acute hospitals. Administration incidents were implicated in the majority of the reported medication incidents (59%), followed by prescribing (10.8%) and dispensing (9.9%), while the nondescript "other medication incidents" accounted for 20.3% of total incidents. The majority of reports were made by nursing and midwifery staff (80%), with medical and dental professionals reporting the lowest number of incidents (n=56, 2%). CONCLUSIONS: The majority of medication incidents in this study were reported by nursing and midwifery staff, and were due to administration incidents. There is a clear need to elucidate the reasons for the limited contribution of the medical and dental professionals to reporting medication incidents.

    Prevalence of heart failure (HF) increases significantly with age, coinciding with age-related changes in body composition that are common and consequential. Still, body composition is rarely factored in routine HF care. The Health, Aging, and Body Composition study is a prospective cohort study of nondisabled adults. Using yearly dual-energy x-ray absorptiometry, body composition was assessed in the Health, Aging, and Body Composition study over 6 years, comparing those who developed incident HF versus those who did not. Among 2815 Health, Aging, and Body Composition participants (48.5% men; 59.6% whites; mean age, 73.6±2.9 years), 111 developed incident HF over the 6-year study period. At entry into the Health, Aging, and Body Composition study, men and women who later developed HF had higher total body mass when compared with those versus those who did not develop HF (men, 80.9±10 versus 78.6±12.9 kg, P =0.05; women, 72.7±15.0 versus 68.2±14.2 kg, P =0.01, respectively). However, after developing HF, loss of total lean body mass was disproportionate; men with HF lost 654.6 versus 391.4 g/y in non-HF participants, P =0.02. Loss of appendicular lean mass was also greater with HF (-419.9 versus -318.2 g/y; P =0.02), even after accounting for total weight change. Among women with HF, loss of total and appendicular lean mass were also greater than in non-HF participants but not to the extent seen among men. Incident HF in older adults was associated with disproportionate loss of lean mass, particularly among men. Prognostic implications are significant, with key sex-specific inferences on physical function, frailty, disability, and pharmacodynamics that all merit further investigation. © 2017 American Heart Association, Inc.

    Highlights: • HfC naobelts accompanied by HfC nanowires were synthesized by a catalytic CVD method. • HfC nanobelts as a novel structure of HfC ceramic are reported for the first time. • HfC nanobelts have 100–200 μm in lengths and reach up to 10 μm in widths. • The synthesized product is promising field nanoemitters. - Abstract: As a key refractory carbide, hafnium carbide (HfC) is commonly used as structural materials while the field emission (FE) application of HfC in the field of vacuum microelectronics is almost the only one for functional material purposes. Based on its outstanding physical and chemical characteristics, HfC is identified as a potential candidate with satisfactory mechanical properties and long-term and/or high-temperature FE stability for future applications in high-performance field emitters. However, the development of HfC in various FE applications is hindered because it is not facile to fabricate large-scale low-dimensional HfC field nanoemitters. Herein, High-aspect-ratio HfC nanobelts accompanied by HfC nanowires were synthesized on a large scale by a traditional and simple catalytic chemical vapor deposition (CVD) method. Classical vapor–liquid–solid (VLS) theory was employed to explain the growth of the HfC nanowires and nanobelts along axial direction. The thin HfO{sub 2} shell and thin C layer surrounding the nanostructures might give rise to the diameter fluctuation of HfC nanowires and the width increase of HfC nanobelts in lateral direction. Field emission results show that the high-aspect-ratio HfC nanobelts accompanied by the nanowires are promising field nanoemitters, which exhibit excellent field emission properties with a fairly low turn-on field of ∼1.5 V μm{sup −1} and a low current fluctuation less than ∼10%. This suggests that HfC ceramics with high-aspect-ratio nanostructures are ideal cathode material for various field emission applications.

    To explore the causes of failure to activate the rapid response system (RRS). The organisation has a recognised incidence of staff failing to act when confronted with a deteriorating patient and leading to adverse outcomes. A multi-method study using the following: a point prevalence survey to determine the incidence of abnormal simple bedside observations and activation of the rapid response team by clinical staff; a prospective audit of all patients experiencing a cardiac arrest, unplanned intensive care unit admission or death over an 8-week period; structured interviews of staff to explore cognitive and sociocultural barriers to activating the RRS. Southern Health is a comprehensive healthcare network with 570 adult in-patient beds across four metropolitan teaching hospitals in the south-eastern sector of Melbourne. Frequency of physiological instability and outcomes within the in-patient hospital population. Qualitative data from staff interviews were thematically coded. The incidence of physiological instability in the acute adult population was 4.04%. Nearly half of these patients (42%) did not receive an appropriate clinical response from the staff, despite most (69.2%) recognising their patient met physiological criteria for activating the RRS, and being 'quite', or 'very' concerned about their patient (75.8%). Structured interviews with 91 staff members identified predominantly sociocultural reasons for failure to activate the RRS. Despite an organisational commitment to the RRS, clinical staff act on local cultural rules within the clinical environment that are usually not explicit. Better understanding of these informal rules may lead to more appropriate activation of the RRS.

    We report on the sol-gel fabrication, using a dip-coating technique, of low-loss Eu-doped 70SiO2 -(30-x) HfO2-xZnO (x = 2, 5, 7 and 10 mol%) ternary glass-ceramic planar waveguides. Transmission electron microscopy and grazing incident x-ray diffraction experiments confirm the controlled growth of hybrid nanocrystals with an average size of 3 nm-25 nm, composed of ZnO encapsulated by a thin layer of nanocrystalline HfO2, with an increase of ZnO concentration from x = 2 mol% to 10 mol% in the SiO2-HfO2 composite matrix. The effect of crystallization on the local environment of Eu ions, doped in the ZnO-HfO2 hybrid nanocrystal-embedded glass-ceramic matrix, is studied using photoluminescence spectra, wherein an intense mixed-valence state (divalent as well as trivalent) emission of Eu ions is observed. The existence of Eu2+ and Eu3+ in the SiO2-HfO2-ZnO ternary matrix is confirmed by x-ray photoelectron spectroscopy. Importantly, the Eu{}2+,3+-doped ternary waveguides exhibit low propagation losses (0.3 ± 0.2 dB cm-1 at 632.8 nm) and optical transparency in the visible region of the electromagnetic spectrum, which makes ZnO-HfO2 nanocrystal-embedded SiO2-HfO2-ZnO waveguides a viable candidate for the development of on-chip, active, integrated optical devices.

    Full Text Available Objective: To study the distribution and patterns of resistance to antimicrobial agents of normal conjunctival bacteria.Materials and Methods: Conjunctival specimens were collected from 8,224 patients and then cultured, which underwent antimicrobial susceptibility test following standard methods. Patients with infectious symptoms such as erythema or oedema and those using systemic or topical antibiotics within 1 month were excluded.Results: In this study, the incidence of isolated bacteria was 24.2%. The middle aged group of 41–65 years presented the lowest rate of bacterial isolation which was 19.4%, while the highest isolation rate (83.1% was found in patients in the age range of 0–6 years. In every age group, the incidence of bacterial isolation in men was higher than that in women. The top 3 most commonly isolated micro-organisms were Staphylococcus epidermidis (39.7%, Streptococcus pneumoniae (4.5%, and Staphylococcus aureus (2.7%, of which about 83.1% S. aureus were isolated in the group of 0-6 years. We found that coagulase-negative Staphylococcus (CONS were more resistant to penicillin, macrolides, clindamycin and sulfonamides with the rate ranging from 57.9 to 90.8%, which were highly susceptible to vancomycin, linezolid, rifampin, tetracyclines, and aminoglycosides. Contrasting to CONS, the general resistance rate of S. aureus was significantly lower. Additionally, Streptococcus was susceptible well to the majority of antimicrobial agents, while highly resistant to macrolides and tetracyclines with the rate >80%.Conclusions: In conclusion, our study revealed the incidence and antimicrobial sensitivity profiles of normal conjunctiva bacterial flora in the central area of China, which could be useful in the prevention of ocular infections. Importantly, our data could be used to guide the selection of appropriate prophylactic agents.

    Cardiac resynchronization therapy (CRT) has been established as a treatment for patients with chronic heart failure (HF). We tested the hypothesis that assessment of peripheral endothelial function is associated with the long-term outcome of CRT and its linkage to coronary flow reserve (CFR) was also investigated. From 2010, a total of 34 consecutive patients implanted with CRT for the treatment of advanced HF were evaluated at baseline (immediately before CRT) and 6-8 months after CRT. Endothelial function was evaluated by measurement of reactive hyperemia peripheral arterial tonometry (RH-PAT). In 24 of 34 patients, CFR was determined by transthoracic echocardiography. Based on the receiver-operating characteristic curves, depressed RH-PAT index (RHI) was defined as ≤1.5. Accurate follow-up information during the mean of 343 ± 120 days was obtained in 20 preserved RHI group (mean age 66 ± 1.8 years) and 14 depressed RHI group (71 ± 2.2 years). Kaplan-Meier survival analysis demonstrated that depressed RHI group had higher prevalence of new hospitalization due to HF progression (log-rank 5.40). Cox proportional hazards regression analysis revealed that the baseline log brain natriuretic peptide (hazard ratio 5.95) and the baseline RHI value (hazard ratio 0.066) were independently associated with the incidence of new hospitalization due to HF progression. The baseline RHI values were positively correlated with the 6-8 months change of CFR (R = 0.434, P = 0.0343). Our results suggest that the baseline peripheral endothelial function could predict the long-term outcome of CRT. The results also suggest that improvement of coronary microcirculation might be associated with the better baseline endothelial function. © 2015 Wiley Periodicals, Inc.

    In the 2004 HF test beam data, signals corresponding to unusually high energies compared to the beam energy were observed and later confirmed in the subsequent test beam study in 2007. These high energy signals most likely result from particles directly hitting the PMTs instead of passing through the fibers to produce Cherenkov radiation, which is the basis of the HF calorimeter. We studied these events using the 2004 HF test beam data confirming the previous results.

    Full Text Available A review is given of the impact that HF radars are having on the management of coastal hazards. Maps of surface currents can be produced every 10–20 minutes which, in real time, improve navigation safety in restricted areas commonly found near ports and harbours. The time sequence of surface current maps enables Lagrangian tracking of small parcels of surface water, which enables hazard mitigation in managing suspended sediments in dredging, in emergency situations where flotsam and other drifting items need to be found, and in pollution control. The surface current measurement capability is used to assist tsunami warnings as shown by the phased-array data from Chile following the Great Tohoku Earthquake in 2011. The newly launched Tsunami Warning Center in Oman includes a network of phased-array HF radars to provide real-time tsunami monitoring. Wind direction maps can be used to locate the position of cold fronts in the open ocean and to monitor the timing and strength of sea-breeze fronts in key locations.

    Full Text Available An accurate knowledge of several metal-boron phase diagrams is important to evaluation of higher order systems such as metal-silicon-boron ternaries. The refinement and reassessment of phase diagram data is a continuous work, thus the reevaluation of metal-boron systems provides the possibility to confirm previous data from an investigation using higher purity materials and better analytical techniques. This work presents results of rigorous microstructural characterization of as-cast hafnium-boron alloys which are significant to assess the liquid composition associated to most of the invariant reactions of this system. Alloys were prepared by arc melting high purity hafnium (minimum 99.8% and boron (minimum 99.5% slices under argon atmosphere in water-cooled copper crucible with non consumable tungsten electrode and titanium getter. The phases were identified by scanning electron microscopy, using back-scattered electron image mode and X-ray diffraction. In general, a good agreement was found between our data and those from the currently accepted Hafnium-Boron phase diagram. The phases identified are αHfSS and B-RhomSS, the intermediate compounds HfB and HfB2 and the liquide L. The reactions are the eutectic L ⇔ αHfSS + HfB and L ⇔ HfB2 + B-Rhom, the peritectic L + HfB2 ⇔ HfB and the congruent formation of HfB2.

    Methods and results: We analyzed Utstein-style data in Sendai City (population 1,020,000, Japan from January 2002 to March 2004. The incidence of OHCA overall was 62.3/100,000/year. The incidence of the bystander-witnessed VF was 2.5/100,000/year. In younger patients (20–65 years of age, the percentage of VF was 52% when cardiac origin was presumed by bystander witness, and ECG was recorded within 10 minutes from the collapse. In older patients (over 65 years of age, however, the percentage of VF was 21% when they were bystander-witnessed, and ECG was recorded within 10 minutes from the collapse. No VF was reported when the ECG was recorded more than 15 minutes after the collapse. The thirty-day survival rate was 21% in the bystander-witnessed VF cases with cardiac etiology, but 0% in the non-VF cases. The bystander CPR was significantly associated with improved 30-day survival rate. Conclusion: Younger age, male gender, and shorter collapse-to-ECG time are significantly associated with the appearance of VF in bystander-witnessed OHCA with cardiac etiology. Bystander CPR was significantly associated with the improvement in prognosis of those VF patients.

    High-temperature x-ray diffraction techniques were used to determine the axial thermal expansion curves of HfTiO 4 -HfO 2 solid solutions as a function of composition. Data show increasing anisotropy with increasing HfO 2 content. An orthorhombic-to-monoclinic phase transformation was detected near room temperature for compositions near the high HfO 2 end of the orthorhombic phase field and for compositions within the two-phase region (HfTiO 4 solid solution plus HfO 2 solid solution). An orthorhombic-to-cubic phase transformation is indicated by data from oxygen-deficient materials at greater than 1873 0 K. (U.S.)

    The authors sought to determine the clinical characteristics and in-hospital survival of women presenting with acute myocardial infarction (AMI) and spontaneous coronary artery dissection (SCAD). The clinical presentation and in-hospital survival of women with AMI and SCAD remains unclear. The National Inpatient Sample (2009 to 2014) was queried for all women with a primary diagnosis of AMI and concomitant SCAD. Iatrogenic coronary dissection was excluded. The main outcome was in-hospital mortality. Propensity score matching and multivariable logistic regression analyses were performed. Among 752,352 eligible women with AMI, 7,347 had a SCAD diagnosis. Women with SCAD were younger (61.7 vs. 67.1 years of age) with less comorbidity. SCAD was associated with higher incidence of in-hospital mortality (6.8% vs. 3.4%). In SCAD patients, a decrease in in-hospital mortality was evident with time (11.4% in 2009 vs. 5.0% in 2014) and concurred with less percutaneous coronary intervention (PCI) (82.5% vs. 69.1%). Propensity score yielded 7,332 SCAD and 14,352 patients without SCAD. The odds ratio (OR) of in-hospital mortality remained higher with SCAD after propensity matching (OR: 1.87, 95% confidence interval [CI]: 1.65 to 2.11) and on multivariable regression analyses (OR: 2.41, 95% CI: 2.07 to 2.80). PCI was associated with higher mortality in SCAD patients presenting with non-ST-segment elevation myocardial infarction (OR: 2.01; 95% CI: 1.00 to 4.47), but not with STEMI (OR: 0.62; 95% CI: 0.41 to 0.96). Women presenting with AMI and SCAD appear to be at higher risk of in-hospital mortality. Lower rates of PCI were associated with improved survival, with evidence of worse outcomes when PCI was performed for SCAD in the setting of non with ST-segment elevation myocardial infarction.

    The electronic structures and magnetic properties of the new Heusler alloys Hf 2 CoGa and Hf 2 CoIn have been studied by using the first-principles projector augmented wave (PAW) potential within the generalized gradient approximation (GGA). Both Hf 2 CoGa and Hf 2 CoIn Heusler alloys have the half-metallic character and completely (100%) spin polarization at the Fermi level (E F ) and the indirect band gaps of 0.733 eV and 0.654 eV, respectively, in the minority spin channel. The total magnetic moments µ t are all 2µ B per formula unit, linearly scaled with the total number of valence electrons (Z t ) by µ t =Z t −18 and the atomic magnetic moments have localized character due to less affected by deformations. The origin of the indirect band gaps for these two new Heusler alloys is well understood. These two new Heusler alloys are the ideal candidates for spintronic devices. - Graphical abstract: The distribution of the magnetic charge density of the Hf 2 CoGa at equilibrium lattice constant. - Highlights: • The Hf 2 CoGa and Hf 2 CoIn are HM ferromagnets with large half-metallic gaps. • The indirect band gaps of Hf 2 CoGa and Hf 2 CoIn are located in minority spin channel. • The total magnetic moments of these two alloys obey the Slater–Pauling rule. • The atomic magnetic moments have the localized characters.

    Full Text Available Abstract Background Disease management programmes (DMPs have been shown to reduce hospital readmissions and mortality in adults with heart failure (HF, but their effectiveness in elderly patients or in those with major comorbidity is unknown. The Multicenter Randomised Trial of a Heart Failure Management Programme among Geriatric Patients (HF-Geriatrics assesses the effectiveness of a DMP in elderly patients with HF and major comorbidity. Methods/Design Clinical trial in 700 patients aged ≥ 75 years admitted with a primary diagnosis of HF in the acute care unit of eight geriatric services in Spain. Each patient should meet at least one of the following comorbidty criteria: Charlson index ≥ 3, dependence in ≥ 2 activities of daily living, treatment with ≥ 5 drugs, active treatment for ≥ 3 diseases, recent emergency hospitalization, severe visual or hearing loss, cognitive impairment, Parkinson's disease, diabetes mellitus, chronic obstructive pulmonary disease (COPD, anaemia, or constitutional syndrome. Half of the patients will be randomly assigned to a 1-year DMP led by a case manager and the other half to usual care. The DMP consists of an educational programme for patients and caregivers on the management of HF, COPD (knowledge of the disease, smoking cessation, immunizations, use of inhaled medication, recognition of exacerbations, diabetes (knowledge of the disease, symptoms of hyperglycaemia and hypoglycaemia, self-adjustment of insulin, foot care and depression (knowledge of the disease, diagnosis and treatment. It also includes close monitoring of the symptoms of decompensation and optimisation of treatment compliance. The main outcome variables are quality of life, hospital readmissions, and overall mortality during a 12-month follow-up. Discussion The physiological changes, lower life expectancy, comorbidity and low health literacy associated with aging may influence the effectiveness of DMPs in HF. The HF-Geriatrics study

    Full Text Available Breast cancer is currently one of the most common malignant tumors of human race and at the same it is the most frequent cancer of female population. The war and post-war migrations of population have significantlychanged the demographic and age structure in Bosnia and Herzegovina. Absence of a National Cancer Register and a unique database on malignant diseases makes monitoring of breast cancer even more difficult.Theobjectiveof this retrospective study was to analyze the incidence of breast cancer in Zenica-Doboj Canton, to conduct a survey based on the age of patients in the five-year period starting from 1 January 2001 until 30 November 2005 and results of the study have been compared with 1990. All the patients were treated surgically with pre-surgical clinical examination, ultra-sound examination and mamography, and pathohistological verification of cancer and pathologically determined size of tumor. A total of 297 patients were treated out of the series of 583 breast surgeries.During this five-year survey a continuous increase of breast cancers in Zenica-Doboj Canton was noted.Therehas been an increased incidence of breast cancer in women aged 30-45, the average size of tumor has decreased, and there has been no change in the relationship between the pathohistological types of tumors and tendencies in surgical treatments to use breast conserving surgical methods. The program of early detection of breast cancer or screening of healthy women and search for “small” cancers (screening programs will enable a wider use of breast conserving surgical methods and it requires a more active involvement of the state and society.

    Recurrence of syncope is a common event, but the influence of recurrent syncope on the risk of death has not previously been investigated on a large scale. We examined the prognostic impact of recurrent syncope in a nationwide cohort of patients with syncope. All patients (n = 70,819) hospitalized from 2001 to 2009 in Denmark with a first-time diagnosis of syncope aged from 15 to 90 years were identified from national registries. Recurrence of syncope was incorporated as a time-dependent variable in multivariable-adjusted Cox models on the outcomes of 30-day, 1-year, and long-term all-cause mortality and cardiovascular death. During a mean follow-up of 3.9 ± 2.6 years, a total of 11,621 patients (16.4%) had at least 1 hospitalization for recurrent syncope, with a median time to recurrence of 251 days (33 to 364). A total of 14,270 patients died, and 3,204 deaths were preceded by a hospitalization for recurrent syncope. The long-term risk of all-cause death was significantly associated with recurrent syncope (hazard ratio 2.64, 95% confidence interval 2.54 to 2.75) compared with those with no recurrence. On 1-year mortality, recurrent syncope was associated with a 3.2-fold increase in risk and on 30-day mortality associated with a threefold increase. The increased mortality risk was consistent over age groups 15 to 39, 40 to 59, and 60 to 89 years, and a similar pattern of increase in both long-term and short-term risk of cardiovascular death was evident. In conclusion, recurrent syncope is independently associated with all-cause and cardiovascular mortality across all age groups exhibiting a high prognostic influence. Increased awareness on high short- and long-term risk of adverse events in subjects with recurrent syncope is warranted for future risk stratification. Copyright © 2014 Elsevier Inc.

    2005-01-01

    We performed a direct observation prepost study to evaluate the impact of barcode technology on medication dispensing errors and potential adverse drug events in the pharmacy of a tertiary-academic medical center. We found that barcode technology significantly reduced the rate of target dispensing errors leaving the pharmacy by 85%, from 0.37% to 0.06%. The rate of potential adverse drug events (ADEs) due to dispensing errors was also significantly reduced by 63%, from 0.19%to 0.069%. In a 735-bed hospital where 6 million doses of medications are dispensed per year, this technology is expected to prevent about 13,000 dispensing errors and 6,000 potential ADEs per year.

    Full Text Available This study is about the incidence of congenital abnormalities in two populations of new born children at Obstetrics and Gynaecology Clinical Hospital of Oradea. First population is represented by the children that were born in the year of 1987. The second population is represented by the children that were born in the year of 2002. We selected these years for this study, because the policy about births is different in the two mentined years. Comparatively with 1987, the abortion is legal. The results are meaningful, because we observed that number of children with congenital abnormalities is bigger in 2002 comparatively with 1987. In spite of all this, the birth rate is smaller in 2002 comparatively with 1987. also, we obtained a significant increased frequency of digestive apparatus congenital abnormalities in comparison with 1987.

    Full Text Available Introduction: The present study aimed to adopt a Plan-do-Study-Act (PDSA cycle to monitor the implementation of Pointing and Calling (P&C in the United Christian Hospital of Hong Kong, China. Materials and Methods: A workgroup was formed to evaluate the approaches to apply P&C in high-alert medication administration using infusion and syringe devices. A series of promulgations and strategies were implemented to increase the probability of its success and sustainability. In addition, pretest and posttest evaluation was performed to monitor the incident rate associated with high-alert medication administration using infusion and syringe devices. Results:Over 100 briefing sessions were conducted in the hospital wards, and 145 senior managers, ward managers, and advanced practice nurses completed the training and assessment. In total, 217 questionnaires, which were scored based on a six-point Likert scale, were collected from 21 wards, with the response rate estimated at 26.53%. Moreover, an audit was performed to obtain 98.1-100% of the compliance rate of using the P&C for evaluation. Since June 2016, the incident rate due to inaccurate device setting decreased from 0.21 to 0.13 after the P&C implementation. Conclusion: According to the results, P&C is a simple method to facilitate the meticulous assessment of high-alert medication administration by nurses. It is recommended that further improvement be made in this regard in order to address the unidentified other areas. Of note, counter measures were proposed to strengthen P&C compliance.

    Full Text Available Patients with heart failure (HF are reportedly at high risk for 'all-cause' re-hospitalization. A biomarker for HF, N-terminal pro-brain natriuretic peptide (NT-proBNP, enables to simply detect patients with possible HF (pHF. We examined the hospitalization and medical cost of Japanese patients detected by an elevated serum NT-proBNP, and also evaluated the effects of institutional team approaches for HF on their all-cause hospitalizations.We retrospectively extracted all adult patients with serum NT-proBNP ≥400 pg/ml measured between January and March 2012 in Hiroshima University Hospital as pHF-positive patients. We studied their all-cause hospitalization records during the past 3-year period. We also extracted all pHF-negative patients with NT-proBNP <400 pg/ml and studied as well. In the pHF-positive patients followed for 3 years after starting interprofessional team approaches to prevent the onset and exacerbation of HF in the hospital, we compared the hospitalization and medical cost between the 3-year periods before and after the start of the team approaches.We enrolled 432 pHF-positive and 485 pHF-negative patients with one or more hospitalization records. Compared to the pHF-negative patients, the pHF-positive patients had longer total hospitalization days (median [interquartile range], 30 [13-58] versus. 18 [8-39], p <0.0001 and higher total medical cost for hospitalizations (2.42 [1.07-5.08] versus. 1.80 [0.79-3.65] million yen, p <0.0001. A subset of 303 pHF-positive patients was followed for 3 years after starting the team approaches, and we found that both total hospitalization days (30 [13-57] to 8 [0-31] and medical cost for hospitalizations (2.59 [1.37-5.05] to 0.76 [0-2.38] million yen showed marked reduction in them.Patients with an elevated serum NT-proBNP have longer hospitalizations and higher costs for all-cause hospitalizations than those without. Institutional team approaches for HF may reduce them.

    Full Text Available Aims: This study was undertaken to estimate the incidence of bacterial vaginosis (BV and other vaginal infections during pregnancy and its association with urinary tract infections (UTI and its consequences on pregnancy outcome, maternal and fetal morbidity and mortality. Settings and Design: Prospective cohort study. Materials and Methods: The present prospective cohort study was conducted on 200 women attending the antenatal clinic (ANC of a tertiary hospital. All pertinent obstetric and neonatal data covering antenatal events during the course of pregnancy, delivery, puerperium and condition of each newborn at the time of birth were collected. BV was detected by both Gram stain and gold standard clinical criteria (Amsel′s composite criteria. Statistical analysis used: Data were analyzed using SPSS version 9. Fischer′s exact test, chi square tests and Student′s′ test has been used for analysis. The probability of 5% was considered as significant for continuous variables such as age, period of gestation and birth weight. Odds ratio (OR and confidence interval (CI with 95% probability were determined. Results: The incidence of bacterial vaginosis was 41 in 200 patients. Adverse outcomes such as preterm labor, PROM and fetal complications were found more in pregnant women who had bacterial vaginosis (N=41, bacterial vaginosis with UTI (N=14 as compared to those without bacterial vaginosis (N=118. Conclusions: The incidence of poor pregnancy outcome was higher in bacterial vaginosis with UTI. Prevention of BV and UTI is cost effective to minimize the pregnancy-related complications and preterm labor to decrease in perinatal and maternal mortality and morbidity. We recommend all antenatal patients should be screened for the presence of bacterial vaginosis, other infections and UTI.

The long-term risk of all-cause death was significantly associated with recurrent syncope (hazard ratio 2.64, 95% confidence interval 2.54 to 2.75) compared with those with no recurrence. On 1-year mortality, recurrent syncope was associated with a 3.2-fold increase in risk...... from 2001 to 2009 in Denmark with a first-time diagnosis of syncope aged from 15 to 90 years were identified from national registries. Recurrence of syncope was incorporated as a time-dependent variable in multivariable-adjusted Cox models on the outcomes of 30-day, 1-year, and long-term all...... and on 30-day mortality associated with a threefold increase. The increased mortality risk was consistent over age groups 15 to 39, 40 to 59, and 60 to 89 years, and a similar pattern of increase in both long-term and short-term risk of cardiovascular death was evident. In conclusion, recurrent syncope...

    We undertook a study programme at the end of 1991. To start with, we performed some exploratory studies aimed at learning some preliminary lessons on this type of analysis: Assessment of the interest of probabilistic incident analysis; possibility of using PSA scenarios; skills and resources required. At the same time, EPN created a working group whose assignment was to define a new approach for analysis of incidents on NPPs. This working group gave thought to both aspects of Operating Feedback that EPN wished to improve: Analysis of significant incidents; analysis of potential consequences. We took part in the work of this group, and for the second aspects, we proposed a method based on an adaptation of the event-tree method in order to establish a link between existing PSA models and actual incidents. Since PSA provides an exhaustive database of accident scenarios applicable to the two most common types of units in France, they are obviously of interest for this sort of analysis. With this method we performed some incident analyses, and at the same time explores some methods employed abroad, particularly ASP (Accident Sequence Precursor, a method used by the NRC). Early in 1994 EDF began a systematic analysis programme. The first, transient phase will set up methods and an organizational structure. 7 figs

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Náuseas e vômitos pós-operatórios (NVPO constituem complicação freqüente e potencialmente grave que aumenta o tempo de recuperação pós-anestésica (RPA e implica insatisfação dos pacientes. Avaliação do risco para NVPO e instituição de profilaxia visando ao bem-estar dos pacientes e à redução de custos têm sido freqüentes em publicações médicas. Este estudo observacional avaliou a incidência, fatores de risco e adequação e efetividade da profilaxia para NVPO na RPA de um hospital-escola terciário. MÉTODO: As informações obtidas a partir de prontuários e questionários aplicados aos pacientes incluíram idade, fatores preditivos maiores para NVPO (sexo feminino, história prévia, não-tabagismo, uso pós-operatório de opióides, profilaxia administrada, ocorrência de NVPO, tipo de cirurgia e anestesia, utilização de óxido nitroso, estado clínico e tempo de permanência na RPA. RESULTADOS: Observou-se incidência de 18,5% de náuseas e 8,5% de vômitos no pós-operatório imediato. Observou-se, ainda, correlação entre fatores maiores de risco e ocorrência de NVPO. Não se observou correlação entre tais fatores e a utilização de medicação antiemética profilática, bem como entre sua utilização e a ocorrência de NVPO. Contudo, observou-se tendência à administração de medicação profilática em pacientes jovens do sexo feminino. CONCLUSÕES: A preocupação dos anestesiologistas da instituição com NVPO ficou estabelecida. Contudo, a ausência de correlação entre risco e profilaxia sugere realização empírica e pouco efetiva. Fatores não-avaliados são sugeridos pela ausência de correlação entre NVPO e o uso de antieméticos. Orientação dos anestesiologistas quanto a condutas profiláticas mais eficientes pode aprimorar os cuidados à população atendida.JUSTIFICATIVA Y OBJETIVOS: Náuseas y vómitos postoperatorios (NVPO constituyen una complicaci

    Full Text Available Background. Disorders connected with the musculoskeletal and central nervous system dysfunction are the most significant clinical problem worldwide. Our earlier research has shown that back and spinal disorders and lumbar disc disorders were most frequently diagnosed using MRI scanner at the University Clinical Hospital (UCH in Olsztyn in years 2011–2015. We have also observed that another two diseases of spinal column, spondylosis and cervical disc disorders, were also very prevalent. The main objective of this work was to analyze the prevalence of spondylosis and cervical disc disorders in the study population diagnosed at UCH in years 2011–2015. Methods. The digital database including patients’ diagnostic and demographic information was generated based on MRI reports from years 2011–2015 and analyzed using SPSS software. Results. Within the study group (n=13298 the most frequently MRI-diagnosed diseases were musculoskeletal group (M00–M99; n=7711; 57,98% and cervical disc disorders (M50; n=1659; 12,47% and spondylosis (M47, n=611; 4,59%. More women (67% than men (33% were enrolled in the study, and the largest fraction of the study population was in the range of 51–60 years, with about 1/3 of cases of both diseases diagnosed in early age range of 31–40 years. Conclusion. Significant number of patients presenting with either of the spine disorders at the young age of 31–40 years points to the necessity of introducing methods preventing disorders of the vertebral column at younger age, preferably at school age.

    This study sought to examine the prevalence and predictors of influenza vaccination among participants in the PARADIGM-HF (Prospective Comparison of ARNI with ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure) study and investigate associations between receiving influenza vaccine and cardiovascular death or heart failure hospitalizations, all-cause hospitalizations, and cardiopulmonary or influenza-related hospitalizations. Influenza is associated with an increased risk for cardiovascular events in patients with heart failure. We used data from the PARADIGM-HF trial in which patients with heart failure were randomized to the angiotensin receptor neprilysin inhibitor LCZ696 (sacubitril/valsartan) or enalapril. We assessed predictors of receiving influenza vaccination, and examined the relationship between influenza vaccination and outcomes in a propensity-adjusted model. Of 8,099 study participants, 1,769 (21%) received influenza vaccination. We observed significant regional variation in vaccination rates, with highest rates in the Netherlands (77.5%), Great Britain (77.2%), and Belgium (67.5%), and lowest rates in Asia (2.6%), with intermediate rates in North America (52.8%). Top predictors of vaccination included enrolling country, white race, implanted defibrillator, older age, lower New York Heart Association functional class, lower heart rate, and a history of diabetes mellitus. Influenza vaccination was associated with a reduced risk for all-cause mortality in propensity-adjusted (hazard ratio: 0.81; 95% confidence interval: 0.67 to 0.97; p = 0.015) models. Influenza vaccination rates varied widely in patients with heart failure with reduced ejection fraction enrolled in the PARADIGM-HF trial, and vaccination was associated with reduced risk for death, although whether this association was causal cannot be determined.

    Full Text Available Adaptive servoventilation (ASV has proven effective at suppressing breathing disturbances during sleep, improving quality of life and cardiac surrogate parameters. Since the publication of the SERVE-HF-trial, ASV became restricted. The purpose of this study was to evaluate the clinical relevance of the SERVE-HF inclusion criteria in real life and estimate the portion of patients with these criteria with or without risk factors who are undergoing ASV treatment. We performed a retrospective study of all patients who were treated with ASV in a university-affiliated sleep laboratory. We reviewed the history of cardiovascular diseases, echocardiographic measurements of left ventricular ejection fraction (LVEF and polysomnography. From 1998 to 2015, 293 patients received ASV, of which 255 (87.0% had cardiovascular diseases and 118 (40.3% had HF. Among those with HF, the LVEF was ≤45% in 47 patients (16.0%. Only 12 patients (4.1% had LVEF <30%. The SERVE-HF inclusion criteria were present in 28 (9.6% ASV recipients. Of these patients, 3 died within 30–58 months of therapy, all with systolic HF and a LVEF <30%. In this study, only a small minority of ASV patients fell in the risk group. The number of fatalities did not exceed the expected mortality in optimally treated systolic HF patients.

    Full Text Available Abstract Background Death of an infant in utero or at birth has always been a devastating experience for the mother and of concern in clinical practice. Infant mortality remains a challenge in the care of pregnant women worldwide, but particularly for developing countries and the need to understand contributory factors is crucial for addressing appropriate perinatal health. Methods Using information available in obstetric records for all deliveries (17,072 births at Harare Maternity Hospital, Zimbabwe, we conducted a cross-sectional retrospective analysis of a one-year data, (1997–1998 to assess demographic and obstetric risk factors for stillbirth and early neonatal death. We estimated risk of stillbirth and early neonatal death for each potential risk factor. Results The annual frequency of stillbirth was 56 per 1,000 total births. Women delivering stillbirths and early neonatal deaths were less likely to receive prenatal care (adjusted relative risk [RR] = 2.54; 95% confidence intervals [CI] 2.19–2.94 and RR = 2.52; 95% CI 1.63–3.91, which for combined stillbirths and early neonatal deaths increased with increasing gestational age (Hazard Ratio [HR] = 3.98, HR = 7.49 at 28 and 40 weeks of gestation, respectively. Rural residence was associated with risk of infant dying in utero, (RR = 1.33; 95% CI 1.12–1.59, and the risk of death increased with increasing gestational age (HR = 1.04, HR = 1.69, at 28 and 40 weeks of gestation, respectively. Older maternal age was associated with risk of death (HR = 1.50; 95% CI 1.21–1.84. Stillbirths were less likely to be delivered by Cesarean section (RR = 0.64; 95% CI 0.51–0.79, but more likely to be delivered as breech (RR = 4.65; 95% CI 3.88–5.57, as were early neonatal deaths (RR = 3.38; 95% CI 1.64–6.96. Conclusion The frequency of stillbirth, especially macerated, is high, 27 per 1000 total births. Early prenatal care could help reduce perinatal death linking the woman to the health

    2003-01-01

    Since its discovery in the 1960's the sup 1 sup 7 sup 8 sup m sup 2 Hf isomer has garnered high attention from both the basic and applied communities in nuclear science. It's combination of high spin (16+), long half life (31 yrs), and high excitation energy (2.446 MeV) offer unique possibilities as an energy storage medium. Interest in the isomer was rekindled beginning in 1999 when a series of publications began to appear from a group (referred to here as the ''Texas collaboration'') primarily based at the University of Texas, Dallas [1]. They reported observations that some of the stored energy could be released (''triggered'') when the isomer was exposed to a fluence of photons in the energy range approx 10 to approx 60 keV. The implications of this observation are profound. Even though the claimed cross section for the process was approx 7 orders of magnitude greater than would be predicted from the known systematics of photon absorption by nuclei in this mass range [2], such a highly efficient method fo...

    2015-08-01

    The Hafnium oxide (HfO2) high-k thin films have been deposited by radio frequency (rf) sputtering technique on p-type Si (100) substrate. The thickness, composition and phases of films in relation to annealing temperatures have been investigated by using cross sectional FE-SEM (Field Emission Scanning Electron Microscope) and grazing incidence x-ray diffraction (GI-XRD), respectively. GI-XRD analysis revealed that at annealing temperatures of 350°C, films phases change to crystalline from amorphous. The capacitance-voltage (C-V) and current-voltage (I-V) characteristics of the annealed HfO2 film have been studied employing Al/HfO2/p-Si metal-oxide-semiconductor (MOS) structures. The electrical properties such as dielectric constant, interface trap density and leakage current density have been also extracted from C-V and I-V Measurements. The value of dielectric constant, interface trap density and leakage current density of annealed HfO2 film is obtained as 23,7.57×1011eV-1 cm-2 and 2.7×10-5 Acm-2, respectively. In this work we also reported the influence of post deposition annealing onto the trapping properties of hafnium oxide and optimized conditions under which no charge trapping is observed into the dielectric stack.

    This study aims to evaluate the associations of early menopause (menopause occurring before age 45 years) and age at menopause with incident heart failure (HF) in postmenopausal women. We also explored the associations of early menopause and age at menopause with left ventricular (LV) measures of structure and function in postmenopausal women. We included 2,947 postmenopausal women, aged 45 to 84 years without known cardiovascular disease (2000-2002), from the Multi-Ethnic Study of Atherosclerosis. Cox proportional hazards models were used to examine the associations of early menopause and age at menopause with incident HF. In 2,123 postmenopausal women in whom cardiac magnetic resonance imaging was obtained at baseline, we explored the associations of early menopause and age at menopause with LV measures using multivariable linear regression. Across a median follow-up of 8.5 years, we observed 71 HF events. There were no significant interactions with ethnicity for incident HF (Pinteraction > 0.05). In adjusted analysis, early menopause was associated with an increased risk of incident HF (hazard ratio, 1.66; 95% CI, 1.01-2.73), whereas every 1-year increase in age at menopause was associated with a decreased risk of incident HF (hazard ratio, 0.96; 95% CI, 0.94-0.99). We observed significant interactions between early menopause and ethnicity for LV mass-to-volume ratio (LVMVR; Pinteraction = 0.02). In Chinese-American women, early menopause was associated with a higher LVMVR (+0.11; P = 0.0002), whereas every 1-year increase in age at menopause was associated with a lower LVMVR (-0.004; P = 0.04) at baseline. Older age at menopause is independently associated with a decreased risk of incident HF. Concentric LV remodeling, indicated by a higher LVMVR, is present in Chinese-American women who experienced early menopause at baseline.

    Full Text Available Hf-N based alloys have been widely used and studied in the fields of electronic devices and cutting tools industry. A thermodynamic description of this system is essential for further materials development. By means of CALPHAD method, a thermodynamic modeling of the Hf-N system was carried out based on the available phase diagram data as well as thermodynamic property data. The Fcc phase is modeled as (Hf, Va1(N, Va1 to cover the composition range since the solubility of nitrogen in Fcc phase is reported up to about 52 at.%. A set of self-consistent thermodynamic parameters for the Hf-N system has been obtained. The computed phase diagrams and thermodynamic quantities using the present parameters agree well with the experimental data.

    2015-10-01

    Abstract—This paper describes modifications to the filter bank multicarrier spread spectrum (FB-MC-SS) system, that was presented in [1] and [2], to enable transmission of this waveform in the HF skywave channel. FB-MC-SS is well suited for the HF channel because it performs well in channels with frequency selective fading and interference. This paper describes new algorithms for packet detection, timing recovery and equalization that are suitable for the HF channel. Also, an algorithm for optimizing the peak to average power ratio (PAPR) of the FBMC- SS waveform is presented. Application of this algorithm results in a waveform with low PAPR. Simulation results using a wide band HF channel model demonstrate the robustness of this system over a wide range of delay and Doppler spreads.

    Anomalous growth of HfAl 3 is observed on 400degreeC annealing of evaporated thin-film samples consisting of 900 A aluminum, on 1000 A hafnium, 6000 A aluminum and SiO 2 substrates. A continuous layer of HfAl 3 forms at the aluminum--hafnium interface nearer the surface, but not at the deeper interface. The surface HfAl 3 layer then continues to grow, fed by diffusion of underlying aluminum through the intervening hafnium layer. Needlelike precipitates of HfAl 3 are formed along the underlying aluminum grain boundaries. Observations are made by nuclear backscattering, Auger electron spectroscopy, and transmission electron microscopy. Similar behavior is observed in Al--Zr--Al layers

    Robert Gałązkowski

    2014-04-01

    Full Text Available In 2013 a fire broke out in the Nursing Home (NH in the Henryszew village 5 km away from the district hospital in Żyrardów. At the time of the incident 52 residents and 16 staff members were present in the building. Due to a large number of casualties, the occurrence was classified as a potentially mass casualty incident (MCI. Troops of the State Fire Brigade, Paramedic Rescue Squads, choppers of the Helicopter Emergency Medical Service, the Police, and the NH staff took part in the rescue operation. The priority was given to the evacuation of the NH residents carried out by the NH staff and firefighters, extinguishing the fire, as well as to primary and secondary survey triage. Due to the pre-accident health state of the victims, the latter posed a considerable difficulty. A decisive role was played by the need to conduct non-invasive measurements of carboxyhemoglobin in all the casualties, which then made it possible to adequately diagnose the patients and implement proper procedures. The rescue operation was correctly followed although it proved to be a serious logistical and technical undertaking for the participating emergency services. The residents were not found to be suffering from carbon monoxide poisoning, therefore 46 of the residents safely returned to the building. The fact that all the Paramedic Rescue Squads were equipped with medical triage sets and were able to conduct non-invasive measurements of carboxyhemoglobin made it possible to introduce effective procedures in the cases of suspected carbon monoxide poisoning and abandon costly and complicated organisational procedures when they proved to be unnecessary.

    We present a theoretical and experimental study of two little-studied manganese phosphide ferromagnets, HfMnP and ZrMnP, with Curie temperatures above room temperature. We find an anisotropy field in HfMnP approaching 10 T - larger than that of the permanent magnet workhorse NdFeB magnets. From theory we determine the source of this anisotropy. Our results show the potential of 3d-element-based magnetic materials for magnetic applications.

We sought to establish temporal changes in maternal age composition and their impact on annual Caesarean section (CS and low birth weight deliveries (LBWT at Muhimbili National Hospital in Tanzania. Methods We conducted data analysis of 91,699 singleton deliveries that took place in the hospital between 1999 and 2005. The data were extracted from the obstetric data base. Annual proportions of individual age groups were calculated and their trends over the years studied. Multiple logistic analyses were conducted to ascertain trends in the risks of CS and LBWT. The impact of age composition changes on CS and LBWT was estimated by calculating annual numbers of these outcomes with and without the major changes in age composition, all others remaining equal. In all statistics, a p value Results The proportion of teenage mothers (12–19 years progressively decreased over time while that of 30–34 years age group increased. From 1999, the risk of Caesarean delivery increased steadily to a maximum in 2005 [adjusted OR = 1.7; 95%CI (1.6–1.8] whereas that of LBWT declined to a minimum in 2005 (adjusted OR = 0.76; 95% CI (0.71–0.82. The current major changes in age trend were responsible for shifts in the number of CS of up to206 cases per year. Likewise, the shift in LBWT was up to 158 cases per year, but the 30–34 years age group had no impact on this. Conclusion The population of mothers giving birth at MNH is progressively becoming older with substantial impact on the incidence of CS and LBWT. Further research is needed to estimate the health cost implications of this change.

    Full Text Available Abstract Two new methods for synthesizing nanostructured HfO2 have been developed. The first method entails exposing HfTe2 powders to air. This simple process resulted in the formation of nanometer scale crystallites of HfO2. The second method involved a two-step heating process by which macroscopic, freestanding nanosheets of HfO2 were formed as a byproduct during the synthesis of HfTe2. These highly two-dimensional sheets had side lengths measuring up to several millimeters and were stable enough to be manipulated with tweezers and other instruments. The thickness of the sheets ranged from a few to a few hundred nanometers. The thinnest sheets appeared transparent when viewed in a scanning electron microscope. It was found that the presence of Mn enhanced the formation of HfO2 by exposure to ambient conditions and was necessary for the formation of the large scale nanosheets. These results present new routes to create freestanding nanostructured hafnium dioxide. PACS: 81.07.-b, 61.46.Hk, 68.37.Hk.

    We have studied the structural stability, electronic structure, optical properties and thermoelectric properties of doped BaHfO{sub 3} by full potential linearized augmented plane wave (FP-LAPW) method. The electronic structure of BaHfO{sub 3} doped with Sr shows enhances the indirect band gaps of 3.53 eV, 3.58 eV. The charge density plots show strong ionic bonding in Ba-Hf, and ionic and covalent bonding between Hf and O. Calculations of the optical spectra, viz., the dielectric function, refractive index and extinction coefficient are performed for the energy range are calculated and analyzed. Thermoelectric properties of semi conducting are also reported first time. The doped BaHfO{sub 3} is approximately wide band gap semiconductor with the large p-type Seebeck coefficient. The power factor of BaHfO{sub 3} is increased with Sr doping, decreases because of low electrical resistivity and thermal conductivity.

    A systematic study of magnetic, magneto-transport and micro-structural properties of Co-HfO{sub 2} granular films fabricated by sequential sputtering is presented. We demonstrate reduction in ferromagnetic-oxide formation by using HfO{sub 2} as the insulting matrix. Microstructure evaluation of the films showed that the film structure consisted of discrete hcp-Co grains embedded in HfO{sub 2} matrix. Films with varying compositions were prepared and their macroscopic properties were studied. We correlate the variation in these properties to the variation in film microstructure. Our study shows that Co-HfO{sub 2} films with reduced cobalt oxide and varying properties can be prepared using sequential sputtering technique. - Highlights: • Co-HfO{sub 2} granular films were prepared using sequential sputtering. • A reduction in ferromagnetic-oxide formation is observed. • Co-HfO{sub 2} films display superparamagnetism and tunnelling magneto-resistance. • Varying macroscopic properties were achieved by changing film composition. • Applications can be found in moderate MR sensors and high –frequency RF devices.

    Details on the mechanism of HF catalyzed isobutylene-isobutane alkylation were investigated. On the basis of available experimental data and high-level quantum chemical calculations, a detailed reaction mechanism is proposed taking into account solvation effects of the medium. On the basis of our computational results, we explain why the density of the liquid media and stirring rates are the most important parameters to achieve maximum yield of alkylate, in agreement with experimental findings. The ab initio Car-Parrinello molecular dynamics calculations show that isobutylene is irreversibly protonated in the liquid HF medium at higher densities, leading to the ion pair formation, which is shown to be a minimum on the potential energy surface after optimization using periodic boundary conditions. The HF medium solvates preferentially the fluoride anion, which is found as solvated [FHF](-) or solvated F(-.)(HF)(3). On the other hand, the tert-butyl cation is weakly solvated, where the closest HF molecules appear at a distance of about 2.9 Angstrom with the fluorine termination of an HF chain.

    Patients in critical care areas are at risk for developing hospital-acquired pressure ulcers (HAPUs) due to their physical conditions and limited ability to reposition themselves. A prospective, 2-phase quality improvement study was conducted from September to November 2011 and from February to April 2012 in 1 medical and 1 surgical ICU to investigate the impact of a turn-and-assist device on the incidence of HAPUs and the time and personnel required to reposition patients reported as person/minutes (staff x minutes). A consecutive, convenience sample of patients was selected from newly admitted ICU patients who were at least 18 years old, nonambulatory, and required 2 or more people to assist with turning and repositioning. Sociodemographic data (patient age, gender, height, weight, body mass index, incontinence status); total Braden score and subscores for Activity, Mobility, and Moisture on admission; length of ICU stay and ventilator days; and sacral pressure ulcer incidence and stage and turn-and-assist data were collected. Fifty (50) patients participated in each phase. In phase 1, standard care for positioning included pillows, underpads, standard low-air-loss beds and additional staff as required for turning. In phase 2, the study product replaced standard care repositioning products including pillows; and a larger disposable moisture-wicking underpad (included as part of the turn study project kit) was substituted for the smaller, standard moisture-wicking disposable underpad. Turning procedures were timed with a stopwatch. Data were collected for a total of 32 hours during the observation periods; all patients were followed from admission until discharge from the ICU for a maximum of 14 days. T-tests were used to compare patient characteristics and person-minutes needed for repositioning differences, and Fisher's exact test was used to compare the incidence of sacral HAPUs during phase 1 and phase 2 of the study. No statistically significant

    Early defibrillation in out-of-hospital cardiac arrest (OHCA) is of importance to improve survival. In many countries the number of automated external defibrillators (AEDs) is increasing, but the use is low. Guidelines suggest that AEDs should be installed in densely populated areas and in locations with many visitors. Attempts have been made to identify optimal AED locations based on the incidence of OHCA using geographical information systems (GIS), but often on small datasets and the studies are seldom reproduced. The aim of this paper is to investigate if the distribution of public AEDs follows the incident locations of public OHCAs in urban areas of Stockholm County, Sweden. OHCA data were obtained from the Swedish Register for Cardiopulmonary Resuscitation and AED data were obtained from the Swedish AED Register. Urban areas in Stockholm County were objectively classified according to the pan-European digital mapping tool, Urban Atlas (UA). Furthermore, we reclassified and divided the UA land cover data into three classes (residential, non-residential and other areas). GIS software was used to spatially join and relate public AED and OHCA data and perform computations on relations and distance. Between 1 January 2012 and 31 December 2014 a total of 804 OHCAs occurred in public locations in Stockholm County and by December 2013 there were 1828 AEDs available. The incidence of public OHCAs was similar in residential (47.3%) and non-residential areas (43.4%). Fewer AEDs were present in residential areas than in non-residential areas (29.4% vs 68.8%). In residential areas the median distance between OHCAs and AEDs was significantly greater than in non-residential areas (288 m vs 188 m, ppublic OHCAs occurred in areas classified in UA as 'residential areas' with limited AED accessibility. These areas need to be targeted for AED installation and international guidelines need to take geographical location into account when suggesting locations for AED installation

    To evaluate the relationship between creatinine clearance rate (CCR) and the level of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in heart failure (HF) patients and their correlations with HF severity. Two hundred and one Chinese patients were grouped according to the New York Heart Association (NYHA) classification as NYHA 1-2 and 3-4 groups and 135 cases out of heart failure patients as control group. The following variables were compared among these three groups: age, sex, body mass index (BMI), smoking status, hypertension, diabetes, NT-proBNP, creatinine (Cr), uric acid (UA), left ventricular end-diastolic diameter (LVEDD), and CCR. The biomarkers of NT-proBNP, Cr, UA, LVEDD, and CCR varied significantly in the three groups, and these variables were positively correlated with the NHYA classification. The levels of NT-proBNP and CCR were closely related to the occurrence of HF and were independent risk factors for HF. At the same time, there was a significant negative correlation between the levels of NT-proBNP and CCR. The area under the receiver operating characteristic curve suggested that the NT-proBNP and CCR have high accuracy for diagnosis of HF and have clinical diagnostic value. NT-proBNP and CCR may be important biomarkers in evaluating the severity of HF.

    Fully relativistic molecular density-functional calculations of the electronic structures of hydrated, hydrolyzed and fluoride/chloride complexes have been performed for group-4 elements Zr, Hf, and element 104, Rf. Using the electronic density distribution data, relative values of the free energy change for hydrolysis and complex formation reactions were defined. The results show the following trend for the first hydrolysis step of the cationic species: Zr>Hf>Rf in agreement with experiments. For the complex formation in HF solutions, the trend to a decrease from Zr to Hf is continued with Rf, provided no hydrolysis takes place. At pH>0, further fluorination of hydrolyzed species or fluoro-complexes has an inversed trend in the group Rf≥Zr>Hf, with the difference between the elements being very small. For the complex formation in HCl solutions, the trend is continued with Rf, so that Zr>Hf>Rf independently of pH. A decisive energetic factor in hydrolysis or complex formation processes proved to be a predominant electrostatic metal-ligand interaction. Trends in the K d (distribution coefficient) values for the group-4 elements are expected to follow those of the complex formation

    This study aims to investigate the effect of recombinant human brain natriuretic peptide (rhBNP) on renal function and contrast-induced nephropathy (CIN) incidence in ST-segment elevation myocardial infarction and heart failure (STEMI-HF) patients with mild renal insufficiency undergoing primary percutaneous coronary intervention (PCI). A total of 116 participants were randomized into rhBNP (rhBNP, n = 57) and nitroglycerin group (NIT, n = 59), receiving intravenous rhBNP or nitroglycerin from admission to 72 h after PCI. Renal function was assessed by serum creatinine (SCr), estimated glomerular filtration rate (eGFR), Cystatin-C (Cys-C) and β2-microglobulin before and after primary PCI, and calculated the incidence of CIN within 72 h after PCI. There were no significant differences in SCr, eGFR and β2-microglobulin between the two groups (P > 0.05, respectively). Compared with the NIT group, the total urinary volume within 72 h was higher while the level of Cys-C at 24 and 72 h after PCI was lower in the rhBNP group. rhBNP was associated with a decline in the incidence of CIN (12.28 vs. 28.81 %, P renal injury was not different between rhBNP and nitroglycerin in STEMI-HF patients with mild renal insufficiency. However, infusion of rhBNP was associated with a decline in incidence of CIN.

Retrospective cohort study. 368 U.S. hospitals in the Premier research database. Individuals aged 65 and older principally hospitalized with pneumonia, COPD, or HF in 2009 or 2010. Proportion of diagnosed episodes of pneumonia, COPD, or HF concurrently treated for two or more of these acute cardiopulmonary conditions during the first 2 hospital days. Of 91,709 diagnosed pneumonia hospitalizations, 32% received treatment for two or more acute cardiopulmonary conditions (18% for HF, 18% for COPD, 4% for both). Of 41,052 diagnosed COPD hospitalizations, 19% received treatment for two or more acute cardiopulmonary conditions (all of which involved additional HF treatment). Of 118,061 diagnosed HF hospitalizations, 38% received treatment for two or more acute cardiopulmonary conditions (34% for pneumonia, 9% for COPD, 5% for both). Hospitalized older adults diagnosed with pneumonia, COPD, or HF are frequently treated for two or more acute cardiopulmonary conditions, suggesting that clinical syndromes often fall between traditional diagnostic categories. Research is needed to evaluate the risks and benefits of real-world treatment for the many older adults whose presentations elicit diagnostic uncertainty or concern about coexisting acute conditions. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    Chronic heart failure (HF) is associated with activation of blood coagulation but there is a lack of prospective studies on the association between coagulation markers and incident HF in general populations. We have examined the association between the coagulation markers fibrinogen, von Willebrand Factor (VWF), Factors VII, VIII and IX, D-dimer, activated protein C (APC) and activated partial thromboplastin time (aPPT) with NT-proBNP and incident HF. Prospective study of 3366 men aged 60-79years with no prevalent HF, myocardial infarction or venous thrombosis and who were not on warfarin, followed up for a mean period of 13years, in whom there were 203 incident HF cases. D-dimer and vWF were significantly and positively associated with NT-proBNP (a marker of neurohormonal activation and left ventricular wall stress) even after adjustment for age, lifestyle characteristics, renal dysfunction, atrial fibrillation (AF) and inflammation (C-reactive protein). By contrast Factor VII related inversely to AF and NT-proBNP even after adjustment. No association was seen however between the coagulation markers VWF, Factor VII, Factor VIII, Factor IX, D-dimer, APC resistance or aPPT with incident HF in age-adjusted analyses. Fibrinogen was associated with incident HF but this was abolished after adjustment for HF risk factors. Coagulation activity is not associated with the development of HF. However D-dimer and vWF were significantly associated with NT-proBNP, suggesting that increased coagulation activity is related to cardiac stress; and the increased coagulation seen in HF patients may in part be a consequence of neurohormonal activation.

    The reference pyro-chemistry process studied by the DRCP is based on an actinide reductive extraction in fluoride media. At the front end of the process, a hydro-fluorination step is needed in order to convert the oxides present in irradiated fuel into fluorides. This hydro-fluorination is carried out with HF gas at 350-500 degrees C. Very few experimental facilities, hot cells, or glove-boxes are equipped with operational HF gas lines: the building and commissioning of such HF lines is very complicated and expensive. This experimental device offers an alternative, enabling hydro-fluorination of small samples (approximate to 5g) of oxide fission product (FP) elements through a chemical reaction involving 'in situ' HF gas generation. A specific gas line would no longer be required, and the hydro-fluorination reaction could therefore be carried out in conventional hot cells or glove-boxes. Ten inactive runs were carried out without any particular problem; there were no gas leaks and no temperature control issues. More than seventeen FP samples were tested. The reliability of the hydro-fluorination set-up through a chemical reaction involving 'in situ' HF gas generation has been demonstrated, and therefore this set-up could be implemented in a hot cell.
