    We examined risk of newly detected human papillomavirus (HPV) infection and cervical abnormalities in relation to HPV type 16/18 antibody levels at enrollment in PATRICIA (Papilloma Trial Against Cancer in Young Adults; NCT00122681). Using Poisson regression, we compared risk of newly detected infection and cervical abnormalities associated with HPV-16/18 between seronegative vs seropositive women (15-25 years) in the control arm (DNA negative at baseline for the corresponding HPV type [HPV-16: n = 8193; HPV-18: n = 8463]). High titers of naturally acquired HPV-16 antibodies and/or linear trend for increasing antibody levels were significantly associated with lower risk of incident and persistent infection, atypical squamous cells of undetermined significance or greater (ASCUS+), and cervical intraepithelial neoplasia grades 1/2 or greater (CIN1+, CIN2+). For HPV-18, although seropositivity was associated with lower risk of ASCUS+ and CIN1+, no association between naturally acquired antibodies and infection was demonstrated. Naturally acquired HPV-16 antibody levels of 371 (95% confidence interval [CI], 242-794), 204 (95% CI, 129-480), and 480 (95% CI, 250-5756) EU/mL were associated with 90% reduction of incident infection, 6-month persistent infection, and ASCUS+, respectively. Naturally acquired antibodies to HPV-16, and to a lesser extent HPV-18, are associated with some reduced risk of subsequent infection and cervical abnormalities associated with the same HPV type. © The Author 2014.

The purpose of this study was to estimate health care resource utilization and costs among COPD patients with newly acquired pneumonia compared to those without pneumonia. Methods: A retrospective claims analysis using Truven MarketScan® Commercial and Medicare databases was conducted. COPD patients with and without newly acquired pneumonia diagnosed between January 1, 2004 and September 30, 2011 were identified. Propensity score matching was used to create a 1:1 matched cohort. Patient demographics, comorbidities (measured by Charlson Comorbidity Index, and medication use were evaluated before and after matching. Health care resource utilization (ie, hospitalizations, emergency room [ER] and outpatient visits, and associated health care costs were assessed during the 12-month follow-up. Logistic regression was conducted to evaluate the risk of hospitalization and ER visits, and gamma regression models and two-part models compared health care costs between groups after matching. Results: In the baseline cohort (N=467,578, patients with newly acquired pneumonia were older (mean age: 70 versus [vs] 63 years and had higher Charlson Comorbidity Index scores (3.3 vs 2.6 than patients without pneumonia. After propensity score matching, the pneumonia cohort was nine times more likely

    Community-acquired pneumonia is associated with a significant long-term mortality after initial recovery. It has been acknowledged that additional research is urgently needed to examine the contributors to this long-term mortality. The objective of the present study was to assess whether diabetes or newly discovered hyperglycaemia during pneumonia affects long-term mortality. A prospective, observational cohort study. A single secondary centre in eastern Finland. 153 consecutive hospitalised patients who survived at least 30 days after mild-to-moderate community-acquired pneumonia. Plasma glucose levels were recorded seven times during the first day on the ward. Several possible confounders were also recorded. The surveillance status and causes of death were recorded after median of 5 years and 11 months. In multivariate Cox regression analysis, a previous diagnosis of diabetes among the whole population (adjusted HR 2.84 (1.35-5.99)) and new postprandial hyperglycaemia among the non-diabetic population (adjusted HR 2.56 (1.04-6.32)) showed independent associations with late mortality. New fasting hyperglycaemia was not an independent predictor. The mortality rates at the end of follow-up were 54%, 37% and 10% among patients with diabetes, patients without diabetes with new postprandial hyperglycaemia and patients without diabetes without postprandial hyperglycaemia, respectively (pdiabetes and newly discovered postprandial hyperglycaemia increase the risk of death for several years after community-acquired pneumonia. As the knowledge about patient subgroups with an increased late mortality risk is gradually gathering, more studies are needed to evaluate the possible postpneumonia interventions to reduce late mortality.

  8. Limited transfer of newly acquired movement patterns across walking and running in humans.

    Directory of Open Access Journals (Sweden)

    Tetsuya Ogawa

    Full Text Available The two major modes of locomotion in humans, walking and running, may be regarded as a function of different speed (walking as slower and running as faster. Recent results using motor learning tasks in humans, as well as more direct evidence from animal models, advocate for independence in the neural control mechanisms underlying different locomotion tasks. In the current study, we investigated the possible independence of the neural mechanisms underlying human walking and running. Subjects were tested on a split-belt treadmill and adapted to walking or running on an asymmetrically driven treadmill surface. Despite the acquisition of asymmetrical movement patterns in the respective modes, the emergence of asymmetrical movement patterns in the subsequent trials was evident only within the same modes (walking after learning to walk and running after learning to run and only partial in the opposite modes (walking after learning to run and running after learning to walk (thus transferred only limitedly across the modes. Further, the storage of the acquired movement pattern in each mode was maintained independently of the opposite mode. Combined, these results provide indirect evidence for independence in the neural control mechanisms underlying the two locomotive modes.

    Osteoporosis is characterized by decreased bone mineral density and mechanistic imbalances of bone tissue that may result in reduced skeletal strength and an enhanced susceptibility to fractures. Osteoporosis in its most common form affects the elderly (both sexes) and all racial groups of human beings. Multiple environmental risk factors like acquired immune deficiency syndrome (AIDS) are believed to be one of the causes of osteoporosis. Recently a high incidence of osteoporosis has been obs...

    Stephanie A Maddox

    Full Text Available The study of the cellular and molecular mechanisms underlying the consolidation and reconsolidation of traumatic fear memories has progressed rapidly in recent years, yet few compounds have emerged that are readily useful in a clinical setting for the treatment of anxiety disorders such as post-traumatic stress disorder (PTSD. Here, we use a combination of biochemical, behavioral, and neurophysiological methods to systematically investigate the ability of garcinol, a naturally-occurring histone acetyltransferase (HAT inhibitor derived from the rind of the fruit of the Kokum tree (Garcina indica, to disrupt the consolidation and reconsolidation of Pavlovian fear conditioning, a widely studied rodent model of PTSD. We show that local infusion of garcinol into the rat lateral amygdala (LA impairs the training and retrieval-related acetylation of histone H3 in the LA. Further, we show that either intra-LA or systemic administration of garcinol within a narrow window after either fear conditioning or fear memory retrieval significantly impairs the consolidation and reconsolidation of a Pavlovian fear memory and associated neural plasticity in the LA. Our findings suggest that a naturally-occurring compound derived from the diet that regulates chromatin function may be useful in the treatment of newly acquired or recently reactivated traumatic memories.

    Identification of factors that confer an increased risk of mortality in hospital acquired sepsis (HAS) is necessary to help prevent, and improve the outcome of, this condition. To evaluate the clinical characteristics and factors associated with mortality in patients with HAS. Retrospective study of patients with HAS in a major Spanish Hospital from 2011 to 2015. Data from adults receiving any of the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes associated with sepsis were collected. Those fulfilling the SEPSIS-2 definition with no evidence of infection during the first 48 hours following hospitalization were included (n=196). A multivariate analysis was employed to identify the risk factors of mortality. HAS patients were found to have many of the risk factors associated with cardiovascular disease (male sex, ageing, antecedent of cardiac disease, arterial hypertension, dyslipemia, smoking habit) and cancer. Vascular disease or chronic kidney disease were associated with 28 day mortality. Time from hospital admission to sepsis diagnosis, and the presence of organ failure were risk factors for 28-day and hospital mortality. Experiencing more than one episode of sepsis increased the risk of hospital mortality. "Sepsis Code" for the early identification of sepsis was protective against hospital mortality. We have identified a number of major factors associated to mortality in patients suffering from HAS. Implementation of surveillance programmes for the early identification and treatment of sepsis translate into a clear benefit. Copyright © 2017 The Healthcare Infection Society.

    Full Text Available Although most recent publications focus on Ventilator-associated Pneumonia, Non-Ventilator-associated Hospital-acquired pneumonia (NVHAP is still worrisome. We studied risk factors for NVHAP among patients admitted to a small teaching hospital. Sixty-six NVHAP case patients and 66 controls admitted to the hospital from November 2005 through November 2006 were enrolled in a case-control study. Variables under investigation included: demographic characteristics, comorbidities, procedures, invasive devices and use of medications (Sedatives, Antacids, Steroids and Antimicrobials. Univariate and multivariable analysis (hierarchical models of logistic regression were performed. The incidence of NVHAP in our hospital was 0.68% (1.02 per 1,000 patients-day. Results from multivariable analysis identified risk factors for NVHAP: age (Odds Ratio[OR]=1.03, 95% Confidence Interval[CI]=1.01-1.05, p=0.002, use of Antacids (OR=5.29, 95%CI=1.89-4.79, p=0.001 and Central Nervous System disease (OR=3.13, 95%CI=1.24-7.93, p=0.02. Although our findings are coherent with previous reports, the association of Antacids with NVHAP recalls a controversial issue in the physiopathology of Hospital-Acquired Pneumonia, with possible implications for preventive strategies.

    Full Text Available Abstract Background Some forms of pharmacotherapy are shown to increase the risk of community-acquired pneumonia (CAP. The purpose of this study is to investigate whether pharmacotherapy with proton pump inhibitors (PPI, inhaled corticosteroids, and atypical antipsychotics was associated with the increased risk for CAP in hospitalized older adults with the adjustment of known risk factors (such as smoking status and serum albumin levels. Methods A retrospective case-control study of adults aged 65 years or older at a rural community hospital during 2004 and 2006 was conducted. Cases (N = 194 were those with radiographic evidence of pneumonia on admission. The controls were patients without the discharge diagnosis of pneumonia or acute exacerbation of chronic obstructive pulmonary disease (COPD (N = 952. Patients with gastric tube feeding, ventilator support, requiring hemodialysis, metastatic diseases or active lung cancers were excluded. Results Multiple logistic regression analysis revealed that the current use of inhaled corticosteroids (adjusted odds ratio [AOR] = 2.89, 95% confidence interval [CI] = 1.56-5.35 and atypical antipsychotics (AOR = 2.26, 95% CI = 1.23-4.15 was an independent risk factor for CAP after adjusting for confounders, including age, serum albumin levels, sex, smoking status, a history of congestive heart failure, coronary artery disease, and COPD, the current use of PPI, β2 agonist and anticholinergic bronchodilators, antibiotic(s, iron supplement, narcotics, and non-steroidal anti-inflammatory drugs. The crude OR and the AOR of PPI use for CAP was 1.41 [95% CI = 1.03 - 1.93] and 1.18 [95% CI = 0.80 - 1.74] after adjusting for the above confounders, respectively. Lower serum albumin levels independently increased the risk of CAP 1.89- fold by decreasing a gram per deciliter (AOR = 2.89, 95% CI = 2.01 - 4.16.

    Full Text Available There was limited information available in the clinical and public health communities about Sexually Transmitted Infections (STIs among lesbians and bisexual women. This study intends to investigate perceived risks of acquiring STIs among lesbians in Rochester, New York. This research concludes that Rochester area lesbians do not perceive themselves at significant risk of acquiring STIs. A gap exists in the sexual health dialogue between health providers and their lesbian patients. And while there was a broad range of safer sex practices documented in the literature, there seems to be little consensus and few guidelines available as far as motivations to practice safer sex.

    Full Text Available Abstract Background A variable decision in managing community acquired pneumonia (CAP is the initial site of care; in-patient versus outpatient. These variations persist despite comprehensive practice guidelines. Patients with a Pneumonia Severity Index (PSI score lower than seventy have low risk for complications and outpatient antibiotic management is recommended in this group. These patients are generally below the age of fifty years, non-nursing home residents, HIV negative and have no major cardiac, hepatic, renal or malignant diseases. Methods A retrospective analysis of 296 low-risk CAP patients evaluated within a year one period at St. Agnes Hospital, Baltimore, Maryland was undertaken. All patients were assigned a PSI score. 208 (70% were evaluated and discharged from the emergency department (E.D. to complete outpatient antibiotic therapy, while 88 (30% were hospitalized. Patients were sub-stratified into classes I-V according to PSI. A comparison of demographic, clinical, social and financial parameters was made between the E.D. discharged and hospitalized groups. Results Statistically significant differences in favor of the hospitalized group were noted for female gender (CI: 1.46-5.89, p= 0.0018, African Americans (CI: 0.31-0.73, p= 0.004, insurance coverage (CI: 0.19-0.63, p= 0.0034, temperature (CI: 0.04-0.09, p= 0.0001 and pulse rate (CI: 0.03-0.14, p= 0.0001. No statistically significant differences were observed between the two groups for altered mental status, hypotension, tachypnea, laboratory/radiological parameters and social indicators (p>0.05. The average length of stay for in-patients was 3.5 days at about eight time's higher cost than outpatient management. There was no difference in mortality or treatment failures between the two groups. The documentation rate and justifications for hospitalizing low risk CAP patients by admitting physicians was less than optimal. Conclusions High fever, tachycardia, female gender

    Full Text Available Patients who were hospitalized for community-based pneumonia frequently had pre-existing atrial fibrillation (AF and had subsequent cardiovascular complications. Whether patients who had AF would be susceptible to the development of hospital-acquired pneumonia (HAP is a serious concern but this has not been investigated. In our clinics, we have made empirical observation of such susceptibility.To investigate the association between newly developed HAP and pre-existing AF, and to identify whether AF is an independent risk factor for HAP.Hospital data from 8657 sequentially admitted inpatients [1059 patients with AF and 7598 without AF (NAF] were collected from the Department of Cardiology, First Affiliated Hospital of Shantou University Medical College, Shantou, China, from January 1, 2009 to December 31, 2011. Exclusion criteria were: having previous or current pneumonia, pacemakers, sick sinus syndrome and repeated hospitalization. The incidence of HAP (within 48 hours after hospitalization was identified among all the patients.Among the AF patients, 274 had HAP (adjusted rate 25.64% which was significantly higher than the 276 NAF patients who had HAP (adjusted rate 3.66%; P<0.001. The increased risk was also associated with high blood pressure, heart failure and age, but not with gender, smoking, coronary heart disease, diabetes, congenital heart disease. In addition, our multiple regression analysis indicates that AF is an independent risk factor for HAP.We have identified, for the first time, that AF is an important risk factor for HAP. Although additional clinical confirmation is needed, our data provide valuable evidence for use in prevention of HAP which is the most common cause of death from nosocomial infection.

    Background and objective COPD patients with community-acquired pneumonia (CAP) have worse clinical outcomes, as compared to those without COPD. Cardiovascular disease (CVD) is a common comorbidity for COPD patients. Whether COPD with comorbid CVD will increase the risk of CAP is not well investigated. The incidence and factors associated with CAP in COPD patients with and without CVD were analyzed. Methods The medical records of patients with newly diagnosed COPD between 2007 and 2010 were reviewed. The patients’ characteristics, medical history of CVD, occurrence of CAP, and type of medication were recorded. Kaplan–Meier curves were used to assess the differences in cumulative incidence of CAP. Cox’s proportional hazards regression model was used to determine the adjusted hazard ratios with 95% confidence intervals in relation to factors associated with CAP in COPD patients with and without CVD. Results Among 2,440 patients, 475 patients (19.5%) developed CAP during the follow-up period. COPD patients who developed CAP were significantly older, had lower forced expiratory volume in 1 second, frequent severe exacerbation and comorbid CVD, as well as received inhaled corticosteroid (ICS)-containing therapy than those without CAP. The cumulative incidence of CAP was higher in COPD patients with CVD compared to those without CVD. Patients who received ICS-containing therapy had significantly increased risk of developing CAP compared to those who did not. Conclusion For patients with COPD, comorbid CVD is an independent risk factor for developing CAP. ICS-containing therapy may increase the risk of CAP among COPD patients. PMID:27980402

    ABSTRACT This systematic review evaluated the epidemiology of community-acquired pneumonia in children <6 y of age within 90 developing and newly industrialized countries. Literature searches (1990–2011), based on MEDLINE, EMBASE, Cochrane, CAB Global Health, WHO, UNICEF, country-specific websites, conferences, health-technology-assessment agencies, and the reference lists of included studies, yielded 8,734 records; 62 of 340 studies were included in this review. The highest incidence rate among included studies was 0.51 episodes/child-year, for children <5 y of age in Bangladesh. The highest prevalence was in Chinese children <6 months of age (37.88%). The main bacterial pathogens were Streptococcus pneumoniae, Haemophilus influenzae and Mycoplasma pneumoniae and the main viral pathogens were respiratory syncytial virus, adenovirus and rhinovirus. Community-acquired pneumonia remains associated with high rates of morbidity and mortality. Improved and efficient surveillance and documentation of the epidemiology and burden of community-acquired pneumonia across various geographical regions is warranted. PMID:27269963

  3. Increasing newly diagnosed rate and changing risk factors of HCV in Yanbian Prefecture, a high endemic area in China.

    Directory of Open Access Journals (Sweden)

    Hong-Xin Piao

    Full Text Available BACKGROUND: The newly diagnosed rate of HCV infection is increasing in China. However, the risk factors have not been fully identified. Here, a survey was performed in Yanbian Prefecture, a high-endemic area in China. METHODS: We identified newly diagnosed HCV infection in 2007-2011, using the local National Disease Supervision Information Management System from the Chinese Center for Disease Control and Prevention. We determined the risk factors using a case-control survey by questionnaire. RESULTS: Yanbian Prefecture had a rapid increase in the yearly newly diagnosed rate of HCV infection from 32.6 to 72.1/100.000 from the year 2007 to 2011. People aged 50-64 years had a high HCV infection of 43.4%, but only 0.3% of cases were reported in those aged less than 20 years. Cosmetic treatment, family history, blood transfusion, and dental treatment were independent risk factors for HCV infection. Unexpectedly, cosmetic treatments [odd ratio (OR = 5.15, 95% confidence interval (CI = 2.31-11.48, P = 0.00] and family history (OR = 4.68, 95% CI = 2.67-8.75, P = 0.00 showed a higher risk than the conventional risk factors of blood transfusion (OR = 4.49, 95% CI = 1.95-10.37, P = 0.001 and dental treatment (OR = 2.98, 95% CI = 1.42-6.25, P = 0.00. To further analyze the intrafamilial transmission, we found that spouses of HCV patients had an increased risk for acquiring HCV (OR = 5.75, 95% CI: 1.94-17.07, without significant association between either HCV RNA viral load (P = 0.29 or genotype (P = 0.43. CONCLUSIONS: HCV infection was increased in Yanbian Prefecture. Cosmetic treatment was a higher risk factor than medical procedure. HCV infection had a clear family clustering phenomenon, especially between spouses.

    The stability of living situation was examined as a predictor of young people's HIV-related sexual and drug use acts two years after leaving home for the first time. Newly homeless youth aged 12-20 years were recruited in Los Angeles County, California, U.S.A. (n = 261) and Melbourne, Australia (n = 165) and followed longitudinally at 3, 6, 12, 18, and 24 months. Their family history of moves and the type and frequency of moves over the two years following becoming newly homeless were examined. Regression analyses indicated that recent sexual risk two years after becoming newly homeless was not related to the instability of youths' living situations; condom use was higher among youth with more placements in institutional settings and among males. Drug use was significantly related to having moved more often over two years and Melbourne youth used drugs significantly more than youth in Los Angeles.

    This study sought to identify modifiable risk factors for pneumonia in elderly nursing home residents. A cohort of 613 elderly residents (age, >65 years) of 5 nursing homes in the New Haven, Connecticut, area was followed-up prospectively from February 2001 through March 2003. The primary outcome was radiographically documented pneumonia within a 12-month surveillance period. Baseline modifiable risk factors were evaluated for their independent association with pneumonia. Of 613 elderly nursing home residents, 131 (21%) died, and an additional 112 (18%) developed a radiographically documented case of pneumonia during the 12-month surveillance period. Among the 9 candidate modifiable risk factors that were evaluated individually in Cox proportional hazards models adjusting for covariates (i.e., nursing home facility, age, race, coexisting conditions, and immobility), inadequate oral care (hazard ratio [HR], 1.60; 95% confidence interval [CI], 1.06-2.35; P=.024) and swallowing difficulty (HR, 1.65; 95% CI, 1.04-2.62; P=.033) were associated with pneumonia. When modifiable risk factors were evaluated simultaneously in the same Cox proportional hazards model, inadequate oral care (HR, 1.55; 95% CI, 1.04-2.30; P=.030) and swallowing difficulty (HR, 1.61; 95% CI, 1.02-2.55; P=.043) remained independently associated with pneumonia, adjusting for the same covariates. Calculation of population-based attributable fractions showed that 21% of all cases of pneumonia in our cohort could have been avoided if inadequate oral care and swallowing difficulty were not present. Two biologically plausible and modifiable risk factors increased the risk of pneumonia in elderly nursing home residents. These results provide a framework for the development and testing of a targeted pneumonia prevention strategy.

Cardiovascular disease (CVD is a common comorbidity for COPD patients. Whether COPD with comorbid CVD will increase the risk of CAP is not well investigated. The incidence and factors associated with CAP in COPD patients with and without CVD were analyzed. Methods: The medical records of patients with newly diagnosed COPD between 2007 and 2010 were reviewed. The patients’ characteristics, medical history of CVD, occurrence of CAP, and type of medication were recorded. Kaplan–Meier curves were used to assess the differences in cumulative incidence of CAP.

    Objective: To find out the frequency of hypovitaminosis D and its associated risk factors in newly diagnosed pulmonary tuberculosis patients prior to administration of standard anti tuberculosis therapy. Methods: This cross-sectional study was carried out in Ojha Institute of Chest Diseases-DUHS. After approval from BASR and following written informed consent eighty newly diagnosed, as per WHO criteria, tuberculosis patients were enrolled. Prior to the initiation of anti tuberculosis therapy, the serum vitamin D level was determined by 25-OH Vitamin D kit using the chemiluminescent immunoassay (CLIA) method. A cut off value of >30 ng/mL of serum vitamin D was taken as normal whereas a range between 10-30 ng/mL and <10 ng/mL were considered insufficient and deficient respectively. Frequency of socio-demographic associated risk factors of hypovitaminosis D was also determined. Results: Out of eighty newly diagnosed tuberculosis patients 33 (41.25%) were males and 47(58.75%) were females with their ages ranging from 18-50 years. 54 patients (26 male and 28 female patients) were smokers. BMI of all the patients was found to be less than the normal ranges. Hypovitaminosis was present in all the cases. Vitamin D insufficiency was found in 49 participants (20 male and 29 female) whereas 31 patients (13 male and 18 female) were found to be vitamin D deficient. Conclusion: Prevalence of serum vitamin D level derangement is very high in newly diagnosed patients with pulmonary tuberculosis in our local setting which necessitates administration of adjuvant vitamin D along with standard anti tuberculosis therapy.

    Introduction Studies on the prevalence of and risk factors for tuberculosis (TB) among newly diagnosed human immunodeficiency virus (HIV)-infected children in sub-Saharan Africa are scarce and in Nigeria there is paucity of reported data. We determined the prevalence of and risk factors for pulmonary TB (PTB) in newly diagnosed (treatment-naïve) HIV-1 infected children at the pediatric HIV clinic of the Jos University Teaching Hospital (JUTH) in Nigeria. Methods We performed a retrospective analysis of 876 children, aged 2 months – 13 years, diagnosed with HIV-1 infection between July 2005 and December 2012, of which 286 were diagnosed with PTB at presentation after TB screening. The study site was the AIDS Prevention Initiative in Nigeria (APIN)-supported Pediatric HIV clinic at JUTH, Jos. A multivariate forward logistic regression modelling was used to identify risk factors for PTB-HIV co-infection. Results The prevalence of PTB-HIV co-infection was 32% (286/876). Severe immunosuppression (SI) and World Health Organization (WHO) HIV clinical stage 3/4 were identified as independent risk factors for PTB-HIV co-infection in HIV infected children. The odds of PTB-HIV co-infection was increased two-fold in HIV-infected children with WHO clinical stage 3/4 compared to those with stage 1/2 (adjusted odds ratio (AOR) 1.76 [1.31-2.37], p<0.001) and 1.5-fold in children with SI compared to those without SI (AOR 1.52 [1.12-2.06], p=0.007). Conclusion In our setting, the burden of PTB was high among newly diagnosed HIV-infected children, and late WHO HIV clinical stage and severe immunosuppression were associated with PTB-HIV co-infection. Therefore there is a clear need to improve strategies for early diagnosis of both HIV and PTB to optimize clinical outcomes. PMID:27019829

    Hypertension is commonly reported in multiple myeloma (MM) patients and may be associated with older age, disease-related complications and consequences of MM treatments. This study evaluated the incidence rates of and risk factors for hypertension and malignant hypertension in newly-treated MM patients in the United States. Newly-treated adult MM patients were identified from Truven MarketScan claims database from 1/1/05 to 3/31/14. Inclusion criteria were new diagnosis of MM with start of MM treatment, ≥12 months continuous enrollment prior to diagnosis, ≥30 days of continuous enrollment following initial diagnosis, and prescription drug coverage. Non-MM patients were matched for age (within +/- 5 years), sex and distribution of index dates to MM patients. Baseline cardiovascular (CV) comorbidities, incidence rate of hypertension and malignant hypertension in the follow-up period, and risk of hypertension and malignant hypertension based on existing baseline CV comorbidities were evaluated. A total of 7895 MM patients (38% with hypertension history) and 23,685 non-MM patients (24% with hypertension history) were included in the study. Twenty-two percent of MM patients versus 3% of non-MM patients had baseline renal failure. A higher percentage of MM versus non-MM patients had baseline hypertension in combination with renal failure, congestive heart failure or both. The incidence rate of hypertension in MM and non-MM patients was 260 and 178 per 1000 person-years, respectively. There was a 30% increase in the risk of hypertension for MM versus non-MM patients: hazard ratio (HR) 1.30 (95% confidence interval [CI] 1.22, 1.37). In MM patients with a history of hypertension, the risk of malignant hypertension was significantly increased with the following comorbid conditions: cardiomyopathy, HR 2.79 (95% CI 1.20, 6.48); renal failure, HR 2.13 (95% CI 1.36, 3.34); and diabetes mellitus, HR 1.59 (95% CI 1.05, 2.39).

    Patients with multiple myeloma are generally immune-compromised either due to pronounced depression in primary antibody responses or because of anti-myeloma therapy. Infection is a major risk factor for early deaths among these patients. The impact of blood stream infections (BSI) on newly diagnosed myeloma patients has been less studied. We aimed to study the incidence and risk factors of BSI within 3 months after diagnosis of multiple myeloma in a tertiary referral center. Between November 2002 and December 2008, consecutive patients with multiple myeloma in Taipei Veterans General Hospital were retrospectively enrolled. Characteristics of patients with or without BSI were collected. Possible factors associated with development of BSI were analyzed by Cox regression. There were a total of 222 patients. The incidence of BSI within 3 months after diagnosis is 11.7%. The patients with BSI had poorer survival outcomes than those without (mortality rate: 50% vs. 20.9%, p  2 vs. ≤ 2: OR 3.58, p = 0.005) were the independent risk factors of BSI, whereas immunoglobulin deficiency and low absolute lymphocyte count were not associated with risk of BSI development. Our study highlights the characteristic of myeloma patients with BSI and the importance of disease and host factors on risk of BSI. Myeloma patients with risks of BSI should be properly managed to reduce early mortality.

    Urinary tract infections account for as much as one-third of all nosocomial infections. The aim of this study was to examine previously reported characteristics of patients with hospital-acquired urinary tract infections (HA-UTI) using an automated infection monitoring system (Hospital-Acquired Infection Registry: HAIR). A matched case-control study was conducted to investigate the association of risk factors with HA-UTI. Patients with HA-UTI more frequently had indwelling urinary catheters or a disease in the genitourinary or nervous system than the controls. Automated hospital-acquired infection monitoring enables documentation of key risk factors to better evaluate infection control interventions in general or for selected groups of patients.

    Full Text Available Background -Risk factors for acquiring hepatitis C virus (HCV infection have been elucidated in many developed countries but the picture is still not clear in many Middle Eastern Countries including Saudi Arabia. Aim -To investigate possible risk factors for acquiring HCV among Saudis. Methods -Various demographic and medical risk factors that might be associated with the spread of HCV among Saudis were investigated. The population studied included 20 anti-HCV-positive with chronic liver disease (CLD, 30 anti-HCV-positive patients without CLD and 272 anti-HCV-negative Saudi blood donors. All people investigated were of the same age group (>40 years of age. Results -None of the demographic parameters studied (type of job, type of housing, education was found to be significantly associated with acquiring HCV infection among our Saudi patients. On the other hand up to 40% of the anti-HCV-positive patients and irrespective of the condition of liver disease had a history of surgery, and 25% of them had a history of multiple injections. Furthermore, at least 20% of our anti-HCV-positive patients had a history of schistosomiasis which is significantly higher than schistosomiasis among the blood donors (P< 0.005. Conclusion -In addition to blood and blood products, schistosomiasis seems to be a possible risk factor for acquiring HCV among the Saudi population. The association between schistosomiasis and enhancement of HCV infection need to be further elucidated.

    Full Text Available Background and Aims: The aim of this paper was the improvement of diabetes mellitus primary prevention through analysis of the prevalence of diabetogenic risk factors. Materials and Methods: The study group comprises 1590 newly diagnosed subjects with diabetes mellitus in a 24 month period in Ploiesti Municipal Hospital. We analyzed the prevalence in this population of some diabetogenic risk factors reported by different risk scores, including gender, age, body mass index (BMI, waist circumference (CA, physical activity at least 30 minutes a day, daily fruit and vegetable consumption, blood pressure history, family history of diabetes, etc. Results: Two-thirds of the patients declared a recent major stress. 74% had dyslipidemia at enrolment or hypolipidemic treatment. The presence of fetal macrosomia in the personal history was about 21%, from which 66% with a familial diabetes mellitus history. Conclusions: The risk factors` increased prevalence in diabetes mellitus detected in the analyzed sample population should determine an increased vigilance for an early screening of the people at risk, and to an early diagnosis of the disease.

    Full Text Available The aim of this study was to determine the relationship between infection with “persistent” agents of children and the possibility of the development of inflammatory diseases of the respiratory tract such as community-acquired pneumonia and acute bronchitis on the basis of risk management concepts.Materials and methods. 701 children in age from 15 days to 16 years were examined in Nizhny Novgorod and the Nizhny Novgorod region with clinically and radiologically confirmed diagnosis: community-acquired pneumonia, acute bronchitis. This study was performed in the period from 2005 to 2014. The control group consisted of 127 healthy children of different ages. The detection of M. pneumoniae, Сytomegalovirus, Herpes simplex I/II C. pneumoniae was performed by PCR. The concept of risk determination was based on the determination of the absolute risk in the exposed and the no exposed groups, attributable risk, relative risk, the population attributable risk, as well as determining the standard errors for each type of risk and confidence interval.Results. Attributable risk, relative risk, population-attributable risk are statistically significant figures. Attributable risk of development of community-acquired pneumonia was 29,26%; 27,37%; 25,70%; 20,21% for the M. pneumoniae, C. pneumoniae, CMV, HSV I / II respectively. The relative risk was 1,43 for the M. pneumoniae; 1,38 – for C. pneumoniae and CMV; 1,28- for HSV I / II. The presence of persistent pathogens is resulting in increased incidence of communityacquired pneumonia throughout the population (population attributable risk: 4,75% for M. pneumoniae, 0,23% for C. pneumoniae, 5,59% for the CMV and 1,08% for the HSV I/II. Similar calculations were performed for patients with acute bronchitis. The statistical analysis allowed to exclude C. pneumoniae and HSV I / II of the risk factors for communityacquired pneumonia and acute bronchitis.Conclusion. The findings suggest the influence of M

    Superficial vein thrombosis (SVT) increases the risk of venous thrombosis fourfold to sixfold. As most individuals with SVT do not develop venous thrombosis, additional risk factors may explain the risk of developing a venous thrombosis. In the Multiple Environmental and Genetic Assessment of risk factors for venous thrombosis study, we assessed the risk of venous thrombosis in individuals with previous SVT and a mild thrombotic risk factor (smoking or overweight/obesity), a strong risk factor (surgery, hospitalization, plaster cast immobilization, or malignancy), or a reproductive factor in women (oral contraception, postmenopausal hormone therapy, or pregnancy/puerperium). Individuals with previous SVT alone had a 5.5-fold (95% confidence interval [CI], 4.4-6.8) increased risk of venous thrombosis. This was 9.3 (95% CI, 7.2-12.1) combined with a mild thrombotic risk factor, 31.4 (95% CI, 14.6-67.5) with a strong risk factor, and 34.9 (95% CI, 19.1-63.8) in women with a reproductive risk factor. The highest separate risk estimates were found for SVT with surgery (42.5; 95% CI, 10.2-177.6), hospitalization (49.8; 95% CI, 11.9-209.2), or oral contraception (43.0; 95% CI, 15.5-119.3 in women). In conclusion, the risk of venous thrombosis is markedly increased in individuals with previous SVT who have an acquired thrombotic risk factor.

    Several sets of guidelines have advocated initial antibiotic treatment for community-acquired pneumonia due to Gram-negative bacilli in patients with specific risk factors. However, evidence to support this recommendation is scarce. We sought to identify risk factors for community-acquired pneumonia due to Gram-negative bacilli, including Pseudomonas aeruginosa, and to assess outcomes. An observational analysis was carried out on prospectively collected data for immunocompetent adults hospitalized for community-acquired pneumonia in two acute-care hospitals. Cases of pneumonia due to Gram-negative bacilli were compared with those of non-Gram-negative bacilli causes. Sixty-one (2%) of 3272 episodes of community-acquired pneumonia were due to Gram-negative bacilli. COPD (odds ratio (OR) 2.4, 95% confidence interval (CI): 1.2-5.1), current use of corticosteroids (OR 2.8, 95% CI: 1.2-6.3), prior antibiotic therapy (OR 2.6, 95% CI: 1.4-4.8), tachypnoea >or=30 cycles/min (OR 2.1, 95% CI: 1.1-4.2) and septic shock at presentation (OR 6.1, 95% CI: 2.5-14.6) were independently associated with Gram-negative bacilli pneumonia. Initial antibiotic therapy in patients with pneumonia due to Gram-negative bacilli was often inappropriate. These patients were also more likely to require admission to the intensive care unit, had longer hospital stays, and higher early (Gram-negative bacilli is uncommon, but is associated with a poor outcome. The risk factors identified in this study should be considered when selecting initial antibiotic therapy for patients with community-acquired pneumonia.

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

  3. Risk and vulnerability: do socioeconomic factors influence the risk of acquiring HIV in Asia?

    HIV epidemics in Asia have been mainly concentrated among certain population groups such as injecting drug users, sex workers and their clients and men who have sex with men (MSM). HIV risk has also been associated with labour migrants and their partners. Many of the people at risk through these behaviours are very poor, and this raises the question that poverty and social deprivation may be underlying factors that drive the adoption of risk behaviours and can be regarded as 'determinants' of vulnerability to HIV infection in Asia. The study presents some observations of the socioeconomic pattern of HIV spread in Asia, using country-level and household-level data. The discussion then draws tentative conclusions about what is known concerning the mechanisms influencing the risk of HIV acquisition in Asia and what they might imply for programme design and policy. In summary, the data presented here do not support the hypothesis that HIV epidemics in Asia are primarily driven by poverty and social deprivation, though sex inequality and education for women and girls are strongly associated factors. There is clearly a multidimensional relationship between the risk of HIV infection and a host of underlying social and cultural factors that confound any attempt at a single explanation for the HIV epidemic in Asia or elsewhere. There is an undeniable need for further research through multicountry studies and better analysis of existing household data, as well as through further investigation of the quantitative relationship between the barriers to HIV services and the risk of infection. The key message for policy is to seek a broad balance between a focus on prevention and treatment for the higher-risk behaviours without losing sight of the importance of programmes that address vulnerability and behavioural change among the sexually active adult population. The implication of these findings for the allocation of resources for downstream factors such as risk behaviours as

    The very early onset of smoking predicts numerous health problems. The authors conducted the first test of one risk model for elementary school age smoking, known as the acquired preparedness (AP) model of risk, in a cross-sectional sample of 309 5th grade children. The model posits that (a) impulsivity-related personality traits contribute to risk for a variety of risky, maladaptive behaviors; (b) smoking expectancies confer risk only for smoking; and (c) the personality traits contribute to the formation of high risk expectancies for reinforcement from smoking, which in turn increases the likelihood of early onset smoking. The model was supported: the high-risk personality traits distinguished children engaging in any risky, maladaptive behavior from other children, and the smoking expectancies differentiated smokers from all other children. The relationship between personality tendencies to act rashly when experiencing intense positive or negative emotions and smoker status was partially mediated by expectancies for reinforcement from smoking. This model should be investigated longitudinally.

    Full Text Available Previous research has reported reduced serum 25-hydroxyvitamin D (25(OHD levels is associated with acute infectious illness. The relationship between vitamin D status, measured prior to acute infectious illness, with risk of community-acquired pneumonia (CAP and sepsis has not been examined. Community-living individuals hospitalized with CAP or sepsis were age-, sex-, race-, and season-matched with controls. ICD-9 codes identified CAP and sepsis; chest radiograph confirmed CAP. Serum 25(OHD levels were measured up to 15 months prior to hospitalization. Regression models adjusted for diabetes, renal disease, and peripheral vascular disease evaluated the association of 25(OHD levels with CAP or sepsis risk. A total of 132 CAP patients and controls were 60 ± 17 years, 71% female, and 86% Caucasian. The 25(OHD levels <37 nmol/L (adjusted odds ratio (OR 2.57, 95% CI 1.08–6.08 were strongly associated with increased odds of CAP hospitalization. A total of 422 sepsis patients and controls were 65 ± 14 years, 59% female, and 91% Caucasian. The 25(OHD levels <37 nmol/L (adjusted OR 1.75, 95% CI 1.11–2.77 were associated with increased odds of sepsis hospitalization. Vitamin D status was inversely associated with risk of CAP and sepsis hospitalization in a community-living adult population. Further clinical trials are needed to evaluate whether vitamin D supplementation can reduce risk of infections, including CAP and sepsis.

    To assess the incidence of hospital-acquired, surgery-related pressure injury (ulcers) and identify risk factors for these injuries. We used a prospective cohort study to investigate the research question. The study was conducted at a major metropolitan hospital in Brisbane, Australia. Five hundred thirty-four adult patients booked for any surgical procedure expected to last more than 30 minutes were eligible for inclusion. Patients who provided informed consent for study participation were assessed for pressure ulcers, using the European Pressure Ulcer Advisory Panel and National Pressure Ulcer Advisory Panel Guidelines, before entering the operating room and again in the post-anesthetic care unit (PACU). Research nurses and all PACU nurses were trained in skin assessment and in pressure ulcer staging. Patients were not assessed again after their discharge from the PACU. Seven patients (1.3%) had existing pressure injuries (ulcers) and a further 6 (1.3%) developed a surgery-related pressure ulcer. Risk factors associated with surgery-related pressure injuries were similar to non-surgically related risks and included older age, skin condition, and being admitted from a location other than one's own home. Length of surgery was not associated with pressure ulcer development in this cohort. Perioperative nurses play an important role in identifying existing or new pressure injuries. However, many of these nurses are unfamiliar with pressure ulcer classification, so education in this area is essential. Although the incidence of surgically acquired pressure ulcers was low in this cohort, careful skin inspection before and after surgery provides an opportunity for early treatment and may prevent existing lesions progressing to higher stages.

    The acquired immune deficiency syndrome (AIDS) occurs most commonly in homosexual men. This group carries the greatest risk of transmitting AIDS by blood transfusion. Both promiscuous and nonpromiscuous male homosexuals should refrain from giving blood. A leaflet stating this advice was prepared by the Department of Health and Social Security, United Kingdom. In July 1984 a questionnaire was given to all donors attending a blood donor clinic in the west end of London, England. 53% were male. Donors were given a leaflet on AIDS and a questionnaire to complete in private. Those who considered themselves to be in a high risk group were asked to designate their blood for research purposes only. Serum samples from donors who confirmed that they were in the high risk category were tested for antihepatitis B core antigen and anti-human T lymphotropic virus type III (anti-HTLV-III) in addition to the routine screening of donors for hepatitis B surface antigen and syphilis. All high risk donors were men. Homosexuality was the only high risk factor. Of 5000 questionnaires administered between July and October, 614 were not completed or had ambiguous answers. 38 donors who completed the questionnaire beonged to a high risk group. Of these, 7 were positive for antihepatitis B core antigen; none were positive for anti-HTLV-III, T pallidum hemagglatination, or hepatits B surface antigen. Although the homosexual donors had a much lower incidence of sexually transmitted disease than those attending special clinics, this should not encourage complacency. All possible measures must be taken to prevent homosexuals from donating blood.

    Full Text Available BACKGROUND: Previously, we demonstrated that hypofibrinolysis, a decreased capacity to dissolve a blood clot as measured with an overall clot lysis assay, increases the risk of venous thrombosis. Here, we investigated the combined effect of hypofibrinolysis with established risk factors associated with hypercoagulability. METHODS AND FINDINGS: Fibrinolytic potential was determined with a plasma-based clot lysis assay in 2,090 patients with venous thrombosis and 2,564 control participants between 18 and 70 y of age enrolled in the Multiple Environmental and Genetic Assessment (MEGA of risk factors for venous thrombosis study, a population-based case-control study on venous thrombosis. Participants completed a standardized questionnaire on acquired risk factors. Hypofibrinolysis alone, i.e., clot lysis time (CLT in the fourth quartile (longest CLT (in absence of the other risk factor of interest increased thrombosis risk about 2-fold relative to individuals with CLT in the first quartile (shortest CLT. Oral contraceptive use in women with CLT in the first quartile gave an odds ratio (OR of 2.6 (95% confidence interval [CI] 1.6 to 4.0, while women with hypofibrinolysis who used oral contraceptives had an over 20-fold increased risk of venous thrombosis (OR 21.8, 95% CI 10.2 to 46.7. For immobilization alone the OR was 4.3 (95% CI 3.2 to 5.8 and immobilization with hypofibrinolysis increased the risk 10.3-fold (95% CI 7.7 to 13.8. Factor V Leiden alone increased the risk 3.5-fold (95% CI 2.3 to 5.5, and hypofibrinolysis in factor V Leiden carriers gave an OR of 8.1 (95% CI 5.3 to 12.3. The combination of hypofibrinolysis and the prothrombin 20210A mutation did not synergistically increase the risk. All ORs and 95% CIs presented are relative to individuals with CLT in the first quartile and without the other risk factor of interest. CONCLUSIONS: The combination of hypofibrinolysis with oral contraceptive use, immobilization, or factor V Leiden

    Full Text Available Advances and research in biotechnology have applications over a wide range of areas such as microbiology, medicine, the food industry, agriculture, genetically modified organisms and nanotechnology, among others. However, research with pathogenic agents such as virus, parasites, fungi, rickettsia, bacterial microorganisms or genetic modified organisms has generated concern because of their potential biological risk - not only for people, but also for the environment due to their unpredictable behavior. In addition, concern for biosafety is associated with the emergence of new diseases or re-emergence of diseases that were already under control. Biotechnology laboratories require biosafety measures designed to protect their staff, the population and the environment, which may be exposed to hazardous organisms and materials. Laboratory staff training and education is essential, not only to acquire a good understanding about the direct handling of hazardous biological agents but also knowledge of the epidemiology, pathogenicity and human susceptibility to the biological materials used in research. Biological risk can be reduced and controlled by the correct application of internationally recognized procedures such as proper microbiological techniques, proper containment apparatus, adequate facilities, protective barriers and special training and education of laboratory workers. To avoid occupational infections, knowledge about standardized microbiological procedures and techniques and the use of containment devices, facilities and protective barriers is necessary. Training and education about the epidemiology, pathogenicity and biohazards of the microorganisms involved may prevent or decrease the risk. In this way, the scientific community may benefit from the lessons learned in the past to anticipate future problems.

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

    Full Text Available BackgroundPatients with type 2 diabetes have an increased risk of cardiovascular disease. Few studies have evaluated the cardiovascular disease (CVD risk simultaneously using the United Kingdom Prospective Diabetes Study (UKPDS risk engine and non-invasive vascular tests in patients with newly diagnosed type 2 diabetes.MethodsParticipants (n=380; aged 20 to 81 years with newly diagnosed type 2 diabetes were free of clinical evidence of CVD. The 10-year coronary heart disease (CHD and stroke risks were calculated for each patient using the UKPDS risk engine. Carotid intima media thickness (CIMT, flow mediated dilation (FMD, pulse wave velocity (PWV and augmentation index (AI were measured. The correlations between the UKPDS risk engine and the non-invasive vascular tests were assessed using partial correlation analysis, after adjusting for age, and multiple regression analysis.ResultsThe mean 10-year CHD and 10-year stroke risks were 14.92±11.53% and 4.03±3.95%, respectively. The 10-year CHD risk correlated with CIMT (P<0.001, FMD (P=0.017, and PWV (P=0.35 after adjusting for age. The 10-year stroke risk correlated only with the mean CIMT (P<0.001 after adjusting for age. FMD correlated with age (P<0.01 and systolic blood pressure (P=0.09. CIMT correlated with age (P<0.01, HbA1c (P=0.05, and gender (P<0.01.ConclusionThe CVD risk is increased at the onset of type 2 diabetes. CIMT, FMD, and PWV along with the UKPDS risk engine should be considered to evaluate cardiovascular disease risk in patients with newly diagnosed type 2 diabetes.

    To investigate the risk and risk factors for newly developed visual impairment in treated patients with normal-tension glaucoma (NTG) followed up on for 10 years. Patients with NTG, who did not have visual impairment at the initial diagnosis and had undergone intraocular pressure (IOP)-lowering treatment for more than 7 years, were included on the basis of a retrospective chart review. Visual impairment was defined as either low vision (0.05 [20/400] ≤ visual acuity (VA) visual field (VF) visual impairment, Kaplan-Meier survival analysis and generalized linear mixed effects models were utilized. During the 10.8 years mean follow-up period, 20 eyes of 16 patients were diagnosed as visual impairment (12 eyes as low vision, 8 as blindness) among 623 eyes of 411 patients. The cumulative risk of visual impairment in at least one eye was 2.8% at 10 years and 8.7% at 15 years. The risk factors for visual impairment from treated NTG were worse VF mean deviation (MD) at diagnosis and longer follow-up period. The risk of newly developed visual impairment in the treated patients with NTG was relatively low. Worse VF MD at diagnosis and longer follow-up period were associated with development of visual impairment. © 2014 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

    Full Text Available Cerebral vein thrombosis (CVT is an infrequent condition with a large variety of causes that can lead to serious disabilities. However, in 20% to 35% of cases, no cause is found. In this study we evaluated the hereditary (P & C Proteins, antithrombin, mutation of prothrombin G20210A and factor V Leiden, other risk factors (hyperhomocycteinemia, factor VIII, ACL-ab, APL-ab, and OCP and clinical manifestations among a population of Iranian patients with CVT. 18 women and 10 men aged 16 to 50 years with CVT were screened for inherited and acquired coagulation risk factors. No one had an abnormal ACL-ab, APL-ab or antithrombin III deficiency. One had prothrombin G20210A mutation (heterozygot (3.6%. Hyperhomocycteinemia was observed in 5 patients (17.9%. APC-R was decreased in 3 (10.7%. 2 had positive factor V Leiden mutation (heterozygot (7.1%. 17 had an increased of factor VIII (60.7. PS and PC deficiencies were each detected in two cases (7.1%. Conclusion: Our study suggests that screening for inherited thrombophilia may be an integral part in the diagnostic workup and duration of treatment in patients with CVT.

    Hospital-acquired acute kidney injury (HA-AKI) is a potentially preventable cause of morbidity and mortality. Identifying high-risk patients prior to the onset of kidney injury is a key step towards AKI prevention. A national retrospective cohort of 1,620,898 patient hospitalizations from 116 Veterans Affairs hospitals was assembled from electronic health record (EHR) data collected from 2003 to 2012. HA-AKI was defined at stage 1+, stage 2+, and dialysis. EHR-based predictors were identified through logistic regression, least absolute shrinkage and selection operator (lasso) regression, and random forests, and pair-wise comparisons between each were made. Calibration and discrimination metrics were calculated using 50 bootstrap iterations. In the final models, we report odds ratios, 95% confidence intervals, and importance rankings for predictor variables to evaluate their significance. The area under the receiver operating characteristic curve (AUC) for the different model outcomes ranged from 0.746 to 0.758 in stage 1+, 0.714 to 0.720 in stage 2+, and 0.823 to 0.825 in dialysis. Logistic regression had the best AUC in stage 1+ and dialysis. Random forests had the best AUC in stage 2+ but the least favorable calibration plots. Multiple risk factors were significant in our models, including some nonsteroidal anti-inflammatory drugs, blood pressure medications, antibiotics, and intravenous fluids given during the first 48 h of admission. This study demonstrated that, although all the models tested had good discrimination, performance characteristics varied between methods, and the random forests models did not calibrate as well as the lasso or logistic regression models. In addition, novel modifiable risk factors were explored and found to be significant. Published by Oxford University Press on behalf of the American Medical Informatics Association 2015.

    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.

    Full Text Available Introduction. Healthcare-acquired urinary tract infections (HAUTI make up to 40% of all healthcareacquired infections and contribute significantly to hospital morbidity, mortality, and overall cost of treatment. Objective. The aim of our study was to investigate possible risk factors for development of HAUTI caused by multi-drug resistant pathogens. Methods. The prospective case-control study in a large tertiary-care hospital was conducted during a five-year period. The cases were patients with HAUTI caused by multi-drug resistant (MDR pathogens, and the controls were patients with HAUTI caused by non-MDR pathogens. Results. There were 562 (62.6% patients with MDR isolates and 336 (37.4% patients with non-MDR isolates in the study. There were four significant predictors of HAUTI caused by MDR pathogens: hospitalization before insertion of urinary catheter for more than eight days (ORadjusted = 2.763; 95% CI = 1.352-5.647; p = 0.005, hospitalization for more than 15 days (ORadjusted = 2.144; 95% CI = 1.547-2.970; p < 0.001, previous stay in another department (intensive care units, other wards or hospitals (ORadjusted = 2.147; 95% CI = 1.585-2.908; p < 0.001, and cancer of various localizations (ORadjusted = 2.313; 95% CI = 1.255-4.262; p = 0.007. Conclusion. Early removal of urinary catheter and reduction of time spent in a hospital or in an ICU could contribute to a decrease in the rate of HAUTI caused by MDR pathogens.

    The purpose of this study was to develop a method for identifying newly diagnosed tuberculosis (TB) patients at risk for TB adverse events in Tamaulipas, Mexico. Surveillance data between 2006 and 2013 (8431 subjects) was used to develop risk scores based on predictive modelling. The final models revealed that TB patients failing their treatment regimen were more likely to have at most a primary school education, multi-drug resistance (MDR)-TB, and few to moderate bacilli on acid-fast bacilli smear. TB patients who died were more likely to be older males with MDR-TB, HIV, malnutrition, and reporting excessive alcohol use. Modified risk scores were developed with strong predictability for treatment failure and death (c-statistic 0·65 and 0·70, respectively), and moderate predictability for drug resistance (c-statistic 0·57). Among TB patients with diabetes, risk scores showed moderate predictability for death (c-statistic 0·68). Our findings suggest that in the clinical setting, the use of our risk scores for TB treatment failure or death will help identify these individuals for tailored management to prevent these adverse events. In contrast, the available variables in the TB surveillance dataset are not robust predictors of drug resistance, indicating the need for prompt testing at time of diagnosis.

    OBJECTIVES Temperature is universally measured in the hospitalized patient, but the literature on hospital-acquired fever has not been systematically reviewed. This systematic review is intended to provide clinicians with an overview of the incidence, etiology, and outcome of hospital-acquired fever. DATA SOURCES We searched MEDLINE (1970 to 2005), EMBASE (1988 to 2004), and Web of Knowledge. References of all included articles were reviewed. Articles that focused on children, fever in the developing world, classic fever of unknown origin, or specialized patient populations were excluded. REVIEW METHODS Articles were reviewed independently by 2 authors before inclusion; a third author acted as arbiter. RESULTS Of over 1,000 studies reviewed, 7 met the criteria for inclusion. The incidence of hospital-acquired fever ranged from 2% to 17%. The etiology of fever was infection in 37% to 74%. Rates of antibiotic use for patients with a noninfectious cause of fever ranged from 29% to 55% for a mean duration of 6.6 to 9.6 days. Studies varied widely in their methodology and the patient population studied. CONCLUSIONS Limited information is available to guide an evidence-based approach to hospital-acquired fever. We propose criteria to help standardize future studies of this important clinical situation. PMID:17026728

    2012-01-01

    A meta-analysis of odds ratios comparing the risks of participating in transplant tourism by acquiring a kidney abroad to the risks associated with domestic kidney transplant was undertaken. Comparison across 12 medical outcomes indicates transplant tourists are significantly more likely to contract cytomegalovirus, hepatitis B, HIV, post-transplantation diabetes mellitus, and wound infection than those receiving domestic kidney transplant. Results also indicate that domestic kidney transplant recipients experience significantly higher one-yr patient- and graft-survival rates. Analyses are supplemented by independent comparisons of outcomes and provide practitioners with weighted estimates of the proportion of transplant recipients experiencing 15 medical outcomes. Practitioners are encouraged to caution patients of the medical risks associated with transplant tourism. Despite the illegal and unethical nature of transplant tourism, additional efforts are indicated to eliminate the organ trade and to educate wait-listed patients about the risks of transplant tourism.

    . Cases (n=7642) were defined as all patients with a first-discharge diagnosis of community-acquired pneumonia from a hospital during 2000 through 2004. We also selected 34 176 control subjects, who were frequency matched to the cases by age and sex. Data on the use of PPIs and other drugs......, on microbiological samples, on x-ray examination findings, and on comorbid conditions were extracted from local registries. Confounders were controlled by logistic regression. RESULTS: The adjusted odds ratio (OR) associating current use of PPIs with community-acquired pneumonia was 1.5 (95% confidence interval [CI......], 1.3-1.7). No association was found with histamine(2)-receptor antagonists (OR, 1.10; 95% CI, 0.8-1.3) or with past use of PPIs (OR, 1.2; 95% CI, 0.9-1.6). Recent initiation of treatment with PPIs (0-7 days before index date) showed a particularly strong association with community-acquired pneumonia...

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

    ICUs are experiencing an epidemic of patients with acute brain dysfunction (delirium) and weakness, both associated with increased mortality and long-term disability. These conditions are commonly acquired in the ICU and are often initiated or exacerbated by sedation and ventilation decisions and management. Despite > 10 years of evidence revealing the hazards of delirium, the quality chasm between current and ideal processes of care continues to exist. Monitoring of delirium and sedation levels remains inconsistent. In addition, sedation, ventilation, and physical therapy practices proven successful at reducing the frequency and severity of adverse outcomes are not routinely practiced. In this article, we advocate for the adoption and implementation of a standard bundle of ICU measures with great potential to reduce the burden of ICU-acquired delirium and weakness. Individual components of this bundle are evidence based and can help standardize communication, improve interdisciplinary care, reduce mortality, and improve cognitive and functional outcomes. We refer to this as the "ABCDE bundle," for awakening and breathing coordination, delirium monitoring, and exercise/early mobility. This evidence-based bundle of practices will build a bridge across the current quality chasm from the "front end" to the "back end" of critical care and toward improved cognitive and functional outcomes for ICU survivors.

    The aims of this study were to obtain the incidence of infertility, to examine the causes of infertility and to explore risk factors for impaired fecundity in a rural region of northern China using a prospective follow-up design. A total of 2151 newly married couples planning to become pregnant within the next 12 months were enrolled between 2009 and 2012 from two counties of Shanxi Province in northern China. Couples were followed up for at least 1 year or until a clinical pregnancy occurred. Information about clinical pregnancy was obtained. The 12-month and 24-month infertility rates were 13.6% (95% CI 11.9 to 15.3) and 8.5% (95% CI 6.7 to 10.3), respectively. About 63% of women became pregnant within 6 months of follow up, and 86% did so within 12 months of follow up. The main causes of female infertility were ovulation disorders, fallopian tube problems and polycystic ovary syndrome. The primary cause of male infertility was sperm quality problems. Couples who used coal as cooking fuel, women with a higher body mass index, women with long-term health problems, and men who had married at later ages were more likely to have delayed pregnancies.

    Serratia marcescens has rarely been reported as an agent of invasive disease in patients presenting from the community. Furthermore, S marcescens is frequently opportunistic, affecting individuals with serious medical comorbidities including immune suppression and diabetes. A case of a community-acquired S marcescens spontaneous lumbar epidural abscess presenting as cauda equina syndrome is reported in a previously well 36-year-old man with no identifiable risk factors. To the authors' knowledge, this is the first report of invasive S marcescens causing disease in a patient with no medical comorbidities.

    To determine the effectiveness of a recorded information line in communicating health risk during the emergence of a new disease, hantavirus pulmonary syndrome (HPS), in the Edmonton area and to study the accuracy of recall of information about hantavirus among the general public. A random telephone survey of residents five months after a death from HPS had occurred. The number of residents who received their information from the recorded line was quite low (approximately 2%), and more people remembered receiving their information through the news media, particularly television (74%) and newspaper (57%). An information line by itself will not communicate risk effectively during an outbreak or other emergent health situation. However, an information line used in conjunction with news media proved effective in providing ongoing, accurate information and allaying public fears in a low-risk situation.

    Objective To determine the attributable risk of community acquired pneumonia on incidence of heart failure throughout the age range of affected patients and severity of the infection.Design Cohort study.Setting Six hospitals and seven emergency departments in Edmonton, Alberta, Canada, 2000-02.Participants 4988 adults with community acquired pneumonia and no history of heart failure were prospectively recruited and matched on age, sex, and setting of treatment (inpatient or outpatient) with up to five adults without pneumonia (controls) or prevalent heart failure (n=23 060).Main outcome measures Risk of hospital admission for incident heart failure or a combined endpoint of heart failure or death up to 2012, evaluated using multivariable Cox proportional hazards analyses.Results The average age of participants was 55 years, 2649 (53.1%) were men, and 63.4% were managed as outpatients. Over a median of 9.9 years (interquartile range 5.9-10.6), 11.9% (n=592) of patients with pneumonia had incident heart failure compared with 7.4% (n=1712) of controls (adjusted hazard ratio 1.61, 95% confidence interval 1.44 to 1.81). Patients with pneumonia aged 65 or less had the lowest absolute increase (but greatest relative risk) of heart failure compared with controls (4.8% v 2.2%; adjusted hazard ratio 1.98, 95% confidence interval 1.5 to 2.53), whereas patients with pneumonia aged more than 65 years had the highest absolute increase (but lowest relative risk) of heart failure (24.8% v 18.9%; adjusted hazard ratio 1.55, 1.36 to 1.77). Results were consistent in the short term (90 days) and intermediate term (one year) and whether patients were treated in hospital or as outpatients.Conclusion Our results show that community acquired pneumonia substantially increases the risk of heart failure across the age and severity range of cases. This should be considered when formulating post-discharge care plans and preventive strategies, and assessing downstream episodes of

    This study was performed to evaluate the clinical features of community-onset levofloxacin-nonsusceptible pneumococcal pneumonia and to identify risk factors for levofloxacin resistance. Using the database of a surveillance study of community-acquired pneumococcal infections in Asian countries, we conducted a nested case-control study to identify risk factors for levofloxacin-nonsusceptible S. pneumoniae in community-acquired pneumonia in adults. Of 981 patients with pneumococcal pneumonia, 46 (4.7 %) had levofloxacin-nonsusceptible S. pneumoniae, of whom 39 evaluable cases were included in the analysis. All cases were from Korea, Taiwan, and Hong Kong. Among patients with levofloxacin-susceptible S. pneumoniae, 490 controls were selected based on patient country. Of the 39 cases of levofloxacin-nonsusceptible pneumococcal pneumonia, 23 (59.0 %) were classified as healthcare-associated, while 164 (33.5 %) of the 490 controls of levofloxacin-susceptible S. pneumoniae (P = 0.001) were classified as healthcare-associated. Multivariate analysis showed that previous treatment with fluoroquinolones, cerebrovascular disease, and healthcare-associated infection were significantly associated with levofloxacin-nonsusceptible pneumococcal pneumonia (all P < 0.05). Levofloxacin-nonsusceptible pneumococci pose an important new public health threat in our region, and more information on the emergence and spread of these resistant strains will be necessary to prevent spread throughout the population.

    There are different theories about the pathophysiology of sepsis-associated encephalopathy (SAE), and the majority of our knowledge was derived from critically ill patients. 7In less severe sepsis, it is probable that neuroinflammation can be a major aspect of SAE development. We hypothesized that in non-severe septic patients, blood biomarkers of inflammation, endothelial activation, coagulation, and brain function would be different when compared to patients with and without brain dysfunction. A total of 30 patients presenting with community-acquired pneumonia (CAP)-induced sepsis were included of which 10 (33 %) developed SAE. Eight medical patients admitted to the general ward, except due to sepsis or infection, which developed delirium were included as delirium, non-sepsis group. From all measured biomarkers, only brain-derived neurotrophic factor (BDNF), regulated upon activation normal T cell expressed, and presumably secreted (RANTES), and interleukin (IL)-10 where significantly different when compared to SAE and sepsis groups. In addition, SAE patients presented higher levels of BDNF, vascular cellular adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), platelet-derived growth factor (PDGF)-AB/BB and RANTES when compared to delirium patients. In conclusion, the profile of biomarkers differs between SAE, sepsis, and delirium patients, suggesting that pathways related to SAE are different from delirium and from sepsis itself.

  8. 'Fetal programming' and 'functional teratogenesis': on epigenetic mechanisms and prevention of perinatally acquired lasting health risks.

    2004-01-01

    Alterations of the intrauterine and early postnatal nutritional, metabolic, and hormonal environment may cause predispositions to the development of disorders and diseases in later life. Mechanisms responsible for this perinatally acquired 'malprogramming' still remain unclear. It has long been known, however, that hormones are environment-dependent organizers of the developing 'neuroendocrine-immune network', which regulates all fundamental processes of life. When present in nonphysiological concentrations during critical ontogenetic periods, hormones can therefore also act as 'endogenous functional teratogens'. Fetal and neonatal hyperinsulinism is a pathognomic feature in the offspring of diabetic mothers. Perinatal hyperinsulinism also occurs due to early postnatal overfeeding. Data obtained by our group indicate that elevated insulin concentrations during critical periods of perinatal life may induce a lasting 'malprogramming' of neuroendocrine systems regulating body weight, food intake, and metabolism. Similar characteristics may occur due to perinatal hyperleptinism, hypercortisolism etc. Since mechanisms of early 'programming' of obesity, diabetes, and the metabolic syndrome X are unclear, a complex 'neuroendocrine malprogramming' of the regulation of body weight and metabolism may provide a general etiopathogenetic concept in this context, exemplarily revealing critical new implications for chances and challenges of perinatal preventive medicine in the future.

Although most patients respond well to discontinuation of antibiotics, 20%–30% of patients relapse. To initiate early therapeutic measures, the risk factors for recurrent CDI must be identified, although very few Japanese studies have used standard surveillance definitions to identify these risk factors.Methods: We retrospectively reviewed the medical records of patients with health care facility-onset CDI between August 2011 and September 2013. Patients with diarrhea who were positive for Clostridium difficile (via an enzyme immunoassay were defined as having CDI. Clinical data (eg, demographics, comorbidities, medication, laboratory results, and clinical outcomes were evaluated, and multivariate analysis was used to identify risk factors that were associated with recurrent CDI.Results: Seventy-six health care facility-onset CDI cases were identified, with an incidence rate of 0.8 cases per 10,000 patient-days. Fourteen cases (18.4% were recurrent, with 13 patients having experienced a single recurrent episode and one patient having experienced three recurrent episodes. The 30-day and 90-day mortality rates were 7.9% and 14.5%, respectively. Multivariate analysis revealed that recurrent patients were more likely to have underlying malignant disease (odds ratio: 7.98; 95% confidence interval: 1.22–52.2; P=0.03 and a history of intensive care unit hospitalization (odds ratio: 49.9; 95% confidence interval: 1.01–2,470; P=0.049.Conclusion: Intensive care unit hospitalization and malignancy are risk factors for recurrent

Cohort 1 comprised 10,614 adults (≥18 years diagnosed with non-valvular atrial fibrillation within the previous 6 weeks, with ≥1 investigator-defined stroke risk factor (not limited to those in existing risk-stratification schemes, and regardless of therapy. Data collected at baseline included demographics, medical history, care setting, nature of atrial fibrillation, and treatments initiated at diagnosis. The mean (SD age of the population was 70.2 (11.2 years; 43.2% were women. Mean±SD CHADS2 score was 1.9±1.2, and 57.2% had a score ≥2. Mean CHA2DS2-VASc score was 3.2±1.6, and 8,957 (84.4% had a score ≥2. Overall, 38.0% of patients with a CHADS2 score ≥2 did not receive anticoagulant therapy, whereas 42.5% of those at low risk (score 0 received anticoagulant therapy.These contemporary observational worldwide data on non-valvular atrial fibrillation, collected at the end of the vitamin K antagonist-only era, indicate that these drugs are frequently not being used according to stroke risk scores and guidelines, with overuse in patients at low risk and underuse in those at high risk of stroke.ClinicalTrials.gov TRI08888.

    To investigate the postnatal risk of Kawasaki disease and coronary complications from a nationwide birth cohort in Taiwan, a country with the third-highest incidence of Kawasaki disease worldwide. We enrolled children born between 2000 and 2009 with complete postnatal medical care records for 2000-2014 in the Taiwan national database. Out of a total of 2 150 590 live births, we identified 6690 (62.6% boys) patients with Kawasaki disease. The onset was mostly (93.9%) within the first 5 years of life (median, 16 months; 38% during infancy), but was rare within the first 3 months of life. The overall cumulative incidence of Kawasaki disease by age 5 years was 2.78‰ (3.33‰ for boys and 2.17‰ for girls; P Kawasaki disease recurred more often in younger patients (cumulative incidence, 2.3% in infants vs 1.7% in children aged 1-4 years). Coronary complications occurred in 16.2% of the patients, including 4 cases of acute myocardial infarction (3 occuring during the acute stage and 1 occurring 5 years later). The probability of a major cardiac event (infarction, undergoing percutaneous coronary intervention or coronary artery bypass grafting, or death) by adolescence was 1.9%. The postnatal risk of Kawasaki disease was 3‰-4‰ and increased with every birth year. Patients with Kawasaki disease are at substantial risk for a major cardiac events during childhood.

    Acquired sensory hearing loss (SHL) is suggested to be associated with depression. However, some studies have reported conflicting results. Our study investigated the relationship between the prevalence of SHL and the incidence of depression over 12 years of follow-up by using data from the Taiwan National Health Insurance Research Database (NHIRD). We sought to determine the association between SHL and subsequent development of depression and discuss the pathophysiological mechanism underlying the association.Patients with SHL were identified from the NHIRD (SHL cohort). A non-SHL cohort, comprising patients without SHL frequency-matched with the SHL patients according to age group, sex, and the year of diagnosis of SHL at the ratio of 1:4, was constructed, and the incidence of depression was evaluated in both cohorts. A multivariable model was adjusted for age, sex, and comorbidity.The SHL cohort and non-SHL cohort comprised 5043 patients with SHL and 20,172 patients without SHL, respectively. The incidences density rates were 9.50 and 4.78 per 1000 person-years in the SHL cohort and non-SHL cohort, respectively. After adjustment for age, sex, and comorbidities, the risk of depression was higher in the SHL cohort than in the non-SHL cohort (hazard ratio = 1.73, 95% confidence interval = 1.49-2.00).Acquired SHL may increase the risk of subsequent depression. The results demonstrated that SHL was an independent risk factor regardless of sex, age, and comorbidities. Moreover, a strong association between hearing loss and subsequent depression among Taiwanese adults of all ages, particularly those aged ≤49 and >65 years and without using steroids for the treatment of SHL was observed. Prospective clinical and biomedical studies on the relationship between hearing loss and depression are warranted for determining the etiopathology.

  15. Evaluating risks of acquired clinical vulnerability among subjects exposed to E-waste.

    Acquired clinical vulnerability (ACV) results from insults that produce consequential pathophysiological changes and predispose exposed subjects to future disease. ACV comprises a complex biological process that is manifested by exposure to toxicants, generally over the course of many years, and results from subtle changes that occur at the cellular and molecular level. A large proportion of the world's population has already been, or will be, exposed to toxicants emanating from E-waste during the course of their lives. In countries where E-waste recycling is an important economic activity (China, India, among others), the challenge facing researchers is to devise suitable methods for identifying and objectively measuring ACV. Primary prevention can be achieved through legislation/awareness/monitoring and secondary prevention by developing innovative diagnostic tools and corrective measures. Studies in which attempts are made to define the health impact of multiple exposures, as routinely occurs in E-waste recycling, should include measures of as many of the following parameters as possible: (a) characterization of pollutant levels in air/water/soil at the residential or workplace, (b) periodical clinical examination of exposed subjects, (c) assessments of circulating toxicant loads in blood/urine/hair, (d) genomic variation and resultant susceptibility to complex biological responses, (viz, inflammation/dysplasia/immunosuppression/tissue regeneration) that derive from pathway modulation (viz., cytoskeleton/metabolism/cell adhesion/immune system/neuroactive ligand-receptor interaction/cytokine/signaling), (e) routine monitoring of altered gene expression from modulation of hematology or the above-mentioned pathways. E-waste exposure may also serve as a model for the types of multiple exposures that occur in other industrial or environmental exposures. Moreover, the approach used to study and address or alleviate E-waste exposure may also be useful in other

In addition, the Centers for Disease Control and Prevention in the United States and the World Health Organization have both released guidelines recommending the offer of oral PrEP to high-risk populations. The scale-up of PrEP is underway, but several implementation questions remain unanswered. Demonstration projects and open-label extensions of placebo-controlled trials are ongoing and hope to contribute to our understanding of PrEP use and delivery outside the randomized controlled trial setting. Evidence is beginning to emerge from these open-label studies and will be critical for guiding PrEP scale-up. Outside of such studies, PrEP uptake has been slow and several client- and provider-related barriers are limiting uptake. Maximizing the public health impact of PrEP will require rollout to be combined with interventions to promote uptake, support adherence, and prevent increases in risk behavior. Additional PrEP strategies are currently under investigation in placebo-controlled clinical trials and may be available in the

    Full Text Available Background. The effects of smoking on human metabolism are complex. Although smoking increases risk for diabetes mellitus, smoking cessation was also reported to be associated with weight gain and incident diabetes mellitus. We therefore conducted this study to clarify the association between smoking status and newly diagnosed diabetes mellitus. Methods. An analysis was done using the data of a mass health examination performed annually in an industrial park from 2007 to 2013. The association between smoking status and newly diagnosed diabetes mellitus was analyzed with adjustment for weight gain and other potential confounders. Results. Compared with never-smokers, not only current smokers but also ex-smokers in their first two years of abstinence had higher odds ratios (ORs for newly diagnosed diabetes mellitus (never-smokers 3.6%, OR as 1; current smokers 5.5%, OR = 1.499, 95% CI = 1.147–1.960, and p=0.003; ex-smokers in their first year of abstinence 7.5%, OR = 1.829, 95% CI = 0.906–3.694, and p=0.092; and ex-smokers in their second year of abstinence 9.0%, OR = 2.020, 95% CI = 1.031–3.955, and p=0.040. Conclusion. Smoking cessation generally decreased risk for newly diagnosed diabetes mellitus. However, increased odds were seen within the first 2 years of abstinence independently of weight gain.

The true scope of the problem or the risk with different topical anesthetic sprays and endoscopic procedures is unknown.Methods: We retrospectively identified all cases of methemoglobinemia that occurred in a university affiliated community hospital from 2001 to 2007.Results: Eleven cases of methemoglobinemia were identified over the 6-year period. Nine (82% occurred with use of benzocaine spray during transesophageal echocardiography (TEE. Patients who developed methemoglobinemia secondary to the topical anesthetic spray compared to other causes were more likely to be older, have lower mean hemoglobin levels (10.5 ± 0.5 g/dL vs 11.3 ± 0.0 g/dL, and a higher mean methemoglobin concentration at diagnosis (40.8% ± 5.2% vs 24% ± 10%. However, only age reached statistical significance (P = 0.004.Conclusion: In a university-affiliated community hospital, topical anesthetic sprays account for most of the burden of methemoglobinemia. Benzocaine use in the context of TEE caused more methemoglobinemia compared to lidocaine and other endoscopic procedures. This observation supports previous data and findings deserve further study.Keywords: methemoglobinemia, benzocaine, lidocaine, transesophageal echocardiography, endoscopy

    Being diagnosed with cancer constitutes not only an immediate threat to health, but cancer treatments may also have a negative impact on fertility. Retrospective studies show that many survivors regret not having received fertility-related information and being offered fertility preservation at time of diagnosis. This qualitative study investigates newly diagnosed cancer patients' experiences of fertility-related communication and how they reason about the risk of future infertility. Informants were recruited at three cancer wards at a university hospital. Eleven women and 10 men newly diagnosed with cancer participated in individual semi-structured interviews focusing on three domains: experiences of fertility-related communication, decision-making concerning fertility preservation, and thoughts and feelings about the risk of possible infertility. Data was analyzed through qualitative content analysis. The analysis resulted in three sub-themes, 'Getting to know', 'Reacting to the risk' and 'Handling uncertainty', and one main theme 'Women more vulnerable when facing risk for infertility', indicating that women reported more negative experiences related to patient-provider communication regarding fertility-related aspects of cancer treatment, as well as negative emotional reactions to the risk of infertility and challenges related to handling uncertainty regarding future fertility. The informants described distress when receiving treatment with possible impact on fertility and used different strategies to handle the risk for infertility, such as relying on fertility preservation or thinking of alternative ways to achieve parenthood. The negative experiences reported by the female informants may be related to the fact that none of the women, but almost all men, had received information about and used fertility preservation. Women newly diagnosed with cancer seem to be especially vulnerable when facing risk for treatment-induced infertility. Lack of shared decision

    Pneumonia is a common infection, accounting for approximately one million hospitalizations in the United States annually. This potentially life-threatening disease is commonly diagnosed based on history, physical examination, and chest radiograph. To investigate emergency medicine evaluation of community-acquired pneumonia including history, physical examination, imaging, and the use of risk scores in patient assessment. Pneumonia is the number one cause of death from infectious disease. The condition is broken into several categories, the most common being community-acquired pneumonia. Diagnosis centers on history, physical examination, and chest radiograph. However, all are unreliable when used alone, and misdiagnosis occurs in up to one-third of patients. Chest radiograph has a sensitivity of 46-77%, and biomarkers including white blood cell count, procalcitonin, and C-reactive protein provide little benefit in diagnosis. Biomarkers may assist admitting teams, but require further study for use in the emergency department. Ultrasound has shown utility in correctly identifying pneumonia. Clinical gestalt demonstrates greater ability to diagnose pneumonia. Clinical scores including Pneumonia Severity Index (PSI); Confusion, blood Urea nitrogen, Respiratory rate, Blood pressure, age 65 score (CURB-65); and several others may be helpful for disposition, but should supplement, not replace, clinical judgment. Patient socioeconomic status must be considered in disposition decisions. The diagnosis of pneumonia requires clinical gestalt using a combination of history and physical examination. Chest radiograph may be negative, particularly in patients presenting early in disease course and elderly patients. Clinical scores can supplement clinical gestalt and assist in disposition when used appropriately. Published by Elsevier Inc.

    Full Text Available OBJECTIVE: To identify risk factors for the development of hospital-acquired pneumonia (HAP caused by multidrug-resistant (MDR bacteria in non-ventilated patients. METHODS: This was a retrospective observational cohort study conducted over a three-year period at a tertiary-care teaching hospital. We included only non-ventilated patients diagnosed with HAP and presenting with positive bacterial cultures. Categorical variables were compared with chi-square test. Logistic regression analysis was used to determine risk factors for HAP caused by MDR bacteria. RESULTS: Of the 140 patients diagnosed with HAP, 59 (42.1% were infected with MDR strains. Among the patients infected with methicillin-resistant Staphylococcus aureus and those infected with methicillin-susceptible S. aureus, mortality was 45.9% and 50.0%, respectively (p = 0.763. Among the patients infected with MDR and those infected with non-MDR gram-negative bacilli, mortality was 45.8% and 38.3%, respectively (p = 0.527. Univariate analysis identified the following risk factors for infection with MDR bacteria: COPD; congestive heart failure; chronic renal failure; dialysis; urinary catheterization; extrapulmonary infection; and use of antimicrobial therapy within the last 10 days before the diagnosis of HAP. Multivariate analysis showed that the use of antibiotics within the last 10 days before the diagnosis of HAP was the only independent predictor of infection with MDR bacteria (OR = 3.45; 95% CI: 1.56-7.61; p = 0.002. CONCLUSIONS: In this single-center study, the use of broad-spectrum antibiotics within the last 10 days before the diagnosis of HAP was the only independent predictor of infection with MDR bacteria in non-ventilated patients with HAP.

    The current World Health Organization classification of conjunctival melanocytic proliferations divides them into conjunctival nevi and invasive melanoma but, in contrast to other anatomic sites, does not recognize melanoma in situ. All atypical intraepithelial conjunctival proliferations are included in a heterogeneous category designated as primary acquired melanosis (PAM) with atypia. We performed clinicopathologic analysis of 29 cases of PAM with atypia. On the basis of histologic features and frequency of association with invasive melanoma and metastases, we were able to divide our cases into 2 histologic groups. The low-risk group (13 cases) included lesions composed of small to medium size melanocytes with high nuclear to cytoplasmic ratio and small to medium size hyperchromatic nuclei devoid of nucleoli showing predominantly single cell lentiginous growth pattern. Invasive melanoma occurred in only 2 cases from this group. None of these lesions metastasized. The second, high-risk group (16 cases), showed increased frequency of association with invasive melanoma (15/16 cases, 94%) and metastases (4/16 cases, 25%). These lesions were more heterogeneous architecturally but were all composed of melanocytes showing various degrees of epithelioid features such as abundant cytoplasm, vesicular nuclei, or prominent nucleoli. In 4 cases discrete areas showing high-risk and low-risk features were identified. All 4 lesions were associated with invasion. Our findings offer a practical approach for prognostically useful subclassification of PAM with atypia, which emphasizes cytologic features of intraepithelial conjunctival melanocytic proliferation.

    Full Text Available Abstract Background Initial antimicrobial therapy (AB is an important determinant of clinical outcome in patients with severe infections as pneumonia, however well-conducted studies regarding prognostic impact of inadequate initial AB in patients who are not undergoing mechanical ventilation (MV are lacking. In this study we aimed to identify the risk factors for inadequate initial AB and to determine its subsequent impact on outcomes in both ventilator associated pneumonia (VAP and hospital acquired pneumonia (HAP. Methods We retrospectively studied the accuracy of initial AB in patients with pneumonia in a university hospital in Turkey. A total of 218 patients with HAP and 130 patients with VAP were included. For each patient clinical, radiological and microbiological data were collected. Stepwise multivariate logistic regression analysis was used for risk factor analysis. Survival analysis was performed by using Kaplan-Meier method with Log-rank test. Results Sixty six percent of patients in VAP group and 41.3% of patients in HAP group received inadequate initial AB. Multiple logistic regression analysis revealed that the risk factors for inadequate initial AB in HAP patients were; late-onset HAP (OR = 2.35 (95% CI, 1.05-5.22; p = 0.037 and APACHE II score at onset of HAP (OR = 1.06 (95% CI, 1.01-1.12; p = 0.018. In VAP patients; antibiotic usage in the previous three months (OR = 3.16 (95% CI, 1.27-7.81; p = 0.013 and admission to a surgical unit (OR = 2.9 (95% CI, 1.17-7.19; p = 0.022 were found to be independent risk factors for inadequate initial AB. No statistically significant difference in crude hospital mortality and 28-day mortality was observed between the treatment groups in both VAP and HAP. However we showed a significant increase in length of hospital stay, duration of mechanical ventilation and a prolonged clinical resolution in the inadequate AB group in both VAP and HAP.

    Full Text Available To evaluate the risk of premotor symptoms, namely rapid eye movement behavior disorder (RBD, constipation, and depression among patients with newly diagnosed Parkinson disease (PD.A total of 705 PD patients and 2,820 control subjects were selected from the Taiwan National Health Insurance Research Database. Patients were traced back for a maximum of 14 years to determine the diagnoses of RBD, depression, and constipation. Logistic regression analysis was used to identify risk of premotor symptoms for PD. Moreover, subgroup analyses were performed by dividing the patients into a middle-age onset group (≤ 64 years and an old-age onset group (≥ 65 years. The associations between these premotor symptoms and age of PD onset were further examined.An association was found between a history of premotor symptoms and newly diagnosed PD in which a high occurrence of premotor symptoms was identified in PD patients as compared to selected controls (4.3% vs. 1.2% for RBD, 40.4% vs. 24.0% for constipation, and 13.0% vs. 5.1% for depression. The strength of this association remained statistically significant after adjustment for potential confounders (3.69 fold risk for RBD, 2.36 for constipation, and 2.82 for depression, all p < 0.0001. The average interval between premotor symptoms and PD ranged from 4.5 to 6.2 years. RBD and depression carried higher risks for PD in the middle-age onset group than in the old-age onset group (7.20- vs. 2.24-fold risk for RBD, 6.06 vs. 1.40 for depression.The prevalence of premotor symptoms was higher among the PD patients than in the controls. Premotor symptoms appeared to be associated with a higher risk for PD in subjects with an earlier age of onset.

    Identification of risk for continuous positive airway pressure therapy (CPAP) nonadherence prior to home treatment is an opportunity to deliver targeted adherence interventions. Study objectives included the following: (1) test a risk screening questionnaire to prospectively identify CPAP nonadherence risk among adults with newly diagnosed obstructive sleep apnea (OSA), (2) reduce the questionnaire to a minimum item set that effectively identifies 1-month CPAP nonadherence, and (3) examine the diagnostic utility of the screening index. A prospective, longitudinal study at two clinical sleep centers in the USA included adults with newly diagnosed OSA (n=97; AHI≥5 events/h) by polysomnogram (PSG) consecutively recruited to participate. After baseline participant and OSA characteristics were collected, a risk screening questionnaire was administered immediately following CPAP titration polysomnogram. One-month objective CPAP use was collected. Predominantly, white (87%), males (55%), and females (45%) with obesity (BMI 38.3 kg/m2; SD 9.3) and severe OSA (AHI 36.8; SD 19.7) were included. One-month CPAP use was 4.25 h/night (SD 2.35). Nineteen questionnaire items (I-NAP) reliably identified nonadherers defined at point for the I-NAP screening questionnaire were determined to maximize sensitivity (87%) while maintaining specificity>60% (63%). A risk screening questionnaire employed immediately after titration PSG may reliably identify CPAP nonadherers and permit the delivery of targeted interventions to prevent or reduce nonadherence. This novel approach may enhance cost-effectiveness of care and permit appropriate allocation of resources for CPAP adherence.

    Full Text Available Summary Objective: several scores were developed in order to improve the determination of community acquired pneumonia (CAP severity and its management, mainly CURB-65 and SACP score. However, none of them were evaluated for risk assessment of in-hospital mortality, particularly in individuals who were non-immunosuppressed and/or without any comorbidity. In this regard, the present study was carried out. Methods: we performed a cross-sectional study in 272 immunocompetent patients without comorbidities and with a diagnosis of CAP. Performance of CURB- 65 and SCAP scores in predicting in-hospital mortality was evaluated. Also, variables related to death were assessed. Furthermore, in order to design a model of in-hospital mortality prediction, sampled individuals were randomly divided in two groups. The association of the variables with mortality was weighed and, by multiple binary regression, a model was constructed in one of the subgroups. Then, it was validated in the other subgroup. Results: both scores yielded a fair strength of agreement, and CURB-65 showed a better performance in predicting in-hospital mortality. In our casuistry, age, white blood cell counts, serum urea and diastolic blood pressure were related to death. The model constructed with these variables showed a good performance in predicting in-hospital mortality; moreover, only one patient with fatal outcome was not correctly classified in the group where the model was constructed and in the group where it was validated. Conclusion: our findings suggest that a simple model that uses only 4 variables, which are easily accessible and interpretable, can identify seriously ill patients with CAP

    Full Text Available BackgroundIntima-media thickness (IMT of the carotid arteries is known to have a positive correlation with the risk of cardiovascular disease. This study was designed to identify risk factors affecting the progression of carotid IMT in patients with type 2 diabetes mellitus (T2DM.MethodsPatients with newly diagnosed T2DM with carotid IMT measurements were enrolled, and their clinical data and carotid IMT results at baseline and 2 years later were compared.ResultsOf the 171 patients, 67.2% of males and 50.8% of females had abnormal baseline IMT of the left common carotid artery. At baseline, systolic blood pressure, body mass index and smoking in male participants, and fasting plasma glucose and glycated hemoglobin levels in females were significantly higher in patients with abnormal IMT than in those with normal IMT. Low density lipoprotein cholesterol (LDL-C levels in males and high density lipoprotein cholesterol (HDL-C levels in females at the 2-year follow-up were significantly different between the nonprogression and the progression groups. Reduction of the United Kingdom Prospective Diabetes Study (UKPDS 10-year coronary heart disease (CHD risk score after 2 years was generally higher in the nonprogression group than the progression group.ConclusionLDL-C levels in males and HDL-C levels in females at the 2-year follow-up were significantly different between participants with and without progression of carotid IMT. Furthermore, a reduction in the UKPDS 10-year CHD risk score appeared to delay the advancement of atherosclerosis. Therefore, the importance of establishing the therapeutic goal of lipid profiles should be emphasized to prevent the progression of carotid IMT in newly diagnosed T2DM patients.

    Neuroleptic malignant syndrome (NMS) is a potentially lethal antipsychotic drug (APD)-induced thermoregulatory disturbance. We hypothesized that several precautionary measures taken after administeration of APDs might prevent progression to definite NMS. The study group included 657 consecutively admitted drug-free schizophrenia inpatients who received various typical APDs for 28 days. Specific predefined precautionary measures were employed for this group. The comparison group (n=192) consisted of typical APD-treated schizophrenia inpatients in whom such precautionary measures were not imposed. The study group exhibited a significantly lower incidence of definite NMS (1/657=0.2% versus 4/192=2.1%; P=0.01, odds ratio=13.96; 95% confidence interval 1.55-125.63). Antipsychotics were discontinued in 28 patients (28/657=4.3%) from the study group due to NMS (n=1) or early detection of potential NMS-related signs (probable abortive NMS) (n=27). Our findings suggest that specific precautionary measures can effectively reduce the incidence of definite NMS by approximately one order in newly medicated schizophrenia inpatients.

Interactions between SNPs and environmental factors were evaluated using an empirical Bayes-type shrinkage estimator. Six SNPs showed interactions with associated p-values (pint) <1.1×10−3. None of the observed interactions was significant after accounting for multiple testing. The Bayesian False Discovery Probability was used to rank the findings, which indicated three interactions as being noteworthy at 1% prior probability of interaction. SNP rs6828523 was associated with increased ER-negative BC risk in women ≥170cm (OR=1.22, p=0.017), but inversely associated with ER-negative BC risk in women <160cm (OR=0.83, p=0.039, pint=1.9×10−4). The inverse association between rs4808801 and overall BC risk was stronger for women who had had four or more pregnancies (OR=0.85, p=2.0×10−4), and absent in women who had had just one (OR=0.96, p=0.19, pint = 6.1×10−4). SNP rs11242675 was inversely associated with overall BC risk in never/former smokers (OR=0.93, p=2.8×10−5), but no association was observed in current smokers (OR=1.07, p=0.14, pint = 3.4×10−4). In conclusion, recently identified breast cancer susceptibility loci are not strongly modified by established risk factors and the observed potential interactions require confirmation in independent studies.

    Full Text Available BACKGROUND/METHODS: To better understand dengue fever in the elderly, we compared clinical features, World Health Organization (WHO dengue classification and outcomes between adult (<60 and elderly (≥60 dengue patients. We explored the impact of co-morbidity and hospital-acquired infection (HAI on clinical outcomes in the elderly. All patients managed at the Communicable Disease Centre, Singapore, between 2005 and 2008 with positive dengue polymerase chain reaction (PCR or who fulfilled WHO 1997 or 2009 probable dengue criteria with positive dengue IgM were included. RESULTS: Of the 6989 cases, 295 (4.4% were elderly. PCR was positive in 29%. The elderly suffered more severe disease with more dengue haemorrhagic fever (DHF (29.2% vs. 21.4% and severe dengue (SD (20.3% vs. 14.6% (p<0.05.

    Patients with coeliac disease are considered as individuals for whom pneumococcal vaccination is advocated. To quantify the risk of community-acquired pneumonia among patients with coeliac disease, assessing whether vaccination against streptococcal pneumonia modified this risk. We identified all patients with coeliac disease within the Clinical Practice Research Datalink linked with English Hospital Episodes Statistics between April 1997 and March 2011 and up to 10 controls per patient with coeliac disease frequency matched in 10-year age bands. Absolute rates of community-acquired pneumonia were calculated for patients with coeliac disease compared to controls stratified by vaccination status and time of diagnosis using Cox regression in terms of adjusted hazard ratios (HR). Among 9803 patients with coeliac disease and 101 755 controls, respectively, there were 179 and 1864 first community-acquired pneumonia events. Overall absolute rate of pneumonia was similar in patients with coeliac disease and controls: 3.42 and 3.12 per 1000 person-years respectively (HR 1.07, 95% CI 0.91-1.24). However, we found a 28% increased risk of pneumonia in coeliac disease unvaccinated subjects compared to unvaccinated controls (HR 1.28, 95% CI 1.02-1.60). This increased risk was limited to those younger than 65, was highest around the time of diagnosis and was maintained for more than 5 years after diagnosis. Only 26.6% underwent vaccination after their coeliac disease diagnosis. Unvaccinated patients with coeliac disease under the age of 65 have an excess risk of community-acquired pneumonia that was not found in vaccinated patients with coeliac disease. As only a minority of patients with coeliac disease are being vaccinated there is a missed opportunity to intervene to protect these patients from pneumonia. © 2016 John Wiley & Sons Ltd.

    Full Text Available BACKGROUND: Prospective data is sparse on the association between ischemic heart disease (IHD and ankylosing spondylitis (AS in the young. The purpose of this population-based, age- and sex-matched follow-up study was to investigate the risk of IHD in young patients with newly diagnosed AS. METHODS: A total of 4794 persons aged 18 to 45 years with at least two ambulatory visits in 2001 with the principal diagnosis of AS were enrolled in the AS group. The non-AS group consisted of 23970 age- and sex-matched, randomly sampled subjects without AS. The three-year IHD-free survival rate and cumulative incidence of IHD were calculated using the Kaplan-Meier method. The Cox proportional hazards regression model was used to estimate the hazard ratio of IHD after controlling for demographic and cardiovascular co-morbidities. RESULTS: During follow-up, 70 patients in the AS group and 253 subjects in the non-AS group developed IHD. The cumulative incidence rate of IHD over time was higher in the AS group than the non-AS group. The crude hazard ratio of IHD for the AS group was 1.47 (95% CI, 1.13 to 1.92; p = 0.0043 and the adjusted hazard ratio after controlling for demographic characteristics and comorbid medical disorders was 1.47 (95% CI, 1.13 to 1.92; p = 0.0045. CONCLUSIONS: This study showed an increased risk of developing IHD in young patients with newly diagnosed AS.

    Detection of circulating plasma cells (PCs) in multiple myeloma (MM) patients is a well-known prognostic factor. We evaluated circulating PCs by flow cytometry (FC) in 104 patients with active MM at diagnosis by gating on CD38(+)  CD45(-) cells and examined their relationship with cytogenetic risk. Patients had an average follow-up of 36 months. By using a receiver operating characteristics analysis, we estimated the optimal cut-off of circulating PCs for defining poor prognosis to be 41. Patients with high-risk cytogenetics (n = 24) had poor prognosis, independently of circulating PC levels [PC cytogenetics (n = 65) showed a better prognosis when associated with a lower number of circulating PCs (PC cytogenetics confirmed that the co-presence of circulating PCs ≥ 41, older age, Durie-Salmon stage >I and lack of maintenance adversely affected PFS, while OS was adversely affected only by lactate dehydrogenase, older age and lack of maintenance. Our results indicate that the quantification of circulating PCs by a simple two-colour FC analysis can provide useful prognostic information in newly diagnosed MM patients with standard-risk cytogenetics.

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

    The formation of acquired drug resistance is a major reason for the failure of anti-cancer therapies after initial response. Here, we introduce a novel model of acquired oxaliplatin resistance, a sub-line of the non-MYCN-amplified neuroblastoma cell line SK-N-AS that was adapted to growth in the presence of 4000 ng/mL oxaliplatin (SK-N-ASrOXALI4000). SK-N-ASrOXALI4000 cells displayed enhanced chromosomal aberrations compared to SK-N-AS, as indicated by 24-chromosome fluorescence in situ hybridisation. Moreover, SK-N-ASrOXALI4000 cells were resistant not only to oxaliplatin but also to the two other commonly used anti-cancer platinum agents cisplatin and carboplatin. SK-N-ASrOXALI4000 cells exhibited a stable resistance phenotype that was not affected by culturing the cells for 10 weeks in the absence of oxaliplatin. Interestingly, SK-N-ASrOXALI4000 cells showed no cross resistance to gemcitabine and increased sensitivity to doxorubicin and UVC radiation, alternative treatments that like platinum drugs target DNA integrity. Notably, UVC-induced DNA damage is thought to be predominantly repaired by nucleotide excision repair and nucleotide excision repair has been described as the main oxaliplatin-induced DNA damage repair system. SK-N-ASrOXALI4000 cells were also more sensitive to lysis by influenza A virus, a candidate for oncolytic therapy, than SK-N-AS cells. In conclusion, we introduce a novel oxaliplatin resistance model. The oxaliplatin resistance mechanisms in SK-N-ASrOXALI4000 cells appear to be complex and not to directly depend on enhanced DNA repair capacity. Models of oxaliplatin resistance are of particular relevance since research on platinum drugs has so far predominantly focused on cisplatin and carboplatin. PMID:28192521

    Recent reports identify the ratio between absolute neutrophil count (ANC) and absolute lymphocyte count (ALC), called neutrophil to lymphocyte ratio (NLR), as a predictor of progression-free survival (PFS) and overall survival (OS) in various malignancies. We retrospectively examined the NLR in a cohort of 309 newly diagnosed multiple myeloma (MM) patients treated upfront with novel agents. NLR was calculated using data obtained from the complete blood count (CBC) at diagnosis and subsequently correlated with PFS and OS. The median NLR was 1.9 (range 0.4-15.9). Higher NLR was independent of international staging system (ISS) stage, plasma cell infiltration or cytogenetics. The 5-year PFS and OS estimates were, respectively, 18.2 and 36.4 % for patients with NLR ≥ 2 versus 25.5 and 66.6 % in patients with NLR ISS stages. By combining ISS stage and NLR in a model limited to young patients, we found that 19 % of the patients were classified as very low risk, 70 % standard risk and 11 % very high risk. The 5-year estimates were 39.3, 19.4 and 10.9 % for PFS and 95.8, 50.9 and 23.6 % for OS for very low, standard-risk and very high-risk groups. We found NLR to be a predictor of PFS and OS in MM patients treated upfront with novel agents. NLR can be combined with ISS staging system to identify patients with dismal outcome. However, larger cohorts and prospective studies are needed to use NLR as additional parameter to personalise MM therapy in the era of novel agents.

    Correct definition of the level of risk of invasive fungal infections is the first step in improving the targeting of preventive strategies. We investigated the potential relationship between pre-hospitalization exposure to sources of fungi and the development of invasive fungal infections in adult patients with newly diagnosed acute myeloid leukemia after their first course of chemotherapy. From January 2010 to April 2012, all consecutive acute myeloid leukemia patients in 33 Italian centers were prospectively registered. Upon first admission, information about possible pre-chemotherapy risk factors and environmental exposure was collected. We recorded data regarding comorbid conditions, employment, hygienic habits, working and living environment, personal habits, hobbies, and pets. All invasive fungal infections occurring within 30 days after the first course of chemotherapy were recorded. Of the 1,192 patients enrolled in this study, 881 received intensive chemotherapy and were included in the present analysis. Of these, 214 developed an invasive fungal infection, including 77 proven/probable cases (8.7%). Of these 77 cases, 54 were proven/probable invasive mold infections (6.1%) and 23 were proven yeast infections (2.6%). Upon univariate analysis, a significant association was found between invasive mold infections and age, performance status, diabetes, chronic obstructive pulmonary disease, smoking, cocaine use, job, hobbies, and a recent house renovation. Higher body weight resulted in a reduced risk of invasive mold infections. Multivariate analysis confirmed the role of performance status, job, body weight, chronic obstructive pulmonary disease, and house renovation. In conclusion, several hospital-independent variables could potentially influence the onset of invasive mold infections in patients with acute myeloid leukemia. Investigation of these factors upon first admission may help to define a patient’s risk category and improve targeted prophylactic

    Full Text Available Acquired methemoglobinaemia is a relatively rare condition and, therefore infrequently encountered in acute medical practice. Suspicion of the condition may be triggered when the measured PaO2 is ‘out of keeping’ with the oxygen saturations that are discovered with pulse oximetry. We describe two separate cases of acquired methemoglobinaemia secondary to the recreational use of alkyl nitrites (’poppers’. The patients presented at separate times to two different teaching hospitals in London, UK. The similarity of these cases has led the authors to conclude that a raised awareness of this potentially fatal condition, and its association with a widely-available recreational drug, is necessary to ensure a correct and timely diagnosis.

    Control of blood pressure and reduction of cardiovascular risk factors are mandatory in patients with hypertension. The aim of this study was to determine the proportion of patients with controlled hypertension and to describe the cardiovascular risk profile in hypertensive patients followed by general practitioners (GPs) in Morocco. This national, observational, multicentre, prospective, longitudinal study of patients with newly diagnosed hypertension was carried out between September 2011 and December 2011. The use of antihypertensive drugs was evaluated at inclusion and after 3 months of follow up. Uncontrolled hypertension was defined as systolic blood pressure (SBP) ⩾ 140 mmHg or diastolic blood pressure (DBP) ⩾ 90 mmHg at 3 months of follow up. The SCORE scale issued by the European Society of Cardiology (ESC) was used to assess overall cardiovascular risk and probability of experiencing a cardiovascular event within 10 years. A total of 909 hypertensive patients were recruited (62.4% female). Mean age was 56.8 ± 10.6 years. More than half of the patients (53.0%) were between 40-60 years and more than one-third (34.1%) were obese [body mass index (BMI) ⩾ 30 kg/m(2)]. There were significantly more obese females than males ( p high or extremely high cardiovascular risk. Abdominal obesity (measured as waist circumference) was the most common cardiovascular risk factor (61.7%) followed by age (40.5%), dyslipidaemia (36.3%) and diabetes (34.3%). Mean SBP decreased from 168.1 ± 14.8 to 138.3 ± 13.2 mmHg ( p blood pressure was achieved in only 46.8% of patients. Poor compliance (17.1%) and a lack of treatment efficacy (16.9%) were the two main reasons for not achieving the blood pressure target. More than half (53.2%) of the hypertensive patients in our study did not achieve adequate blood pressure control during the 3-month follow-up period and had a high cardiovascular risk. More effective management of hypertension is required in primary care.

  13. Hospital-acquired urinary tract infection point prevalence in Turkey: Differences in risk factors among patient groups

    Science.gov (United States)

    2013-01-01

    Background The aim of this study was to determine the point prevalence of nosocomial urinary tract infections (UTIs) and to investigate risk factors for pathogen type (E. coli vs. others) and extended-spectrum beta-lactamase (ESBL) positivity among nosocomial UTI patients. Methods A questionnaire consisting of 44 questions on demographic data and risk factors of UTI cases was sent to 51 tertiary care hospitals. Univariate and multivariate analyses were conducted. Results The overall prevalence of UTI was 1.82% (483/26534). The prevalence of UTI was higher in intensive care units (ICUs) with 6.77% versus 1.45% outside ICUs. Hospitals of the Ministry of Health (compared to university hospitals), hospitals in less developed provinces and hospitals with bed capacity urinary catheter were more likely to have received immunosuppressive therapy, current corticosteroid use, renal transplantation and uterine prolapsus and less likely to have another infection outside the urinary tract, as compared to catheterized patients. Among the 422 culture-positive patients, the most common pathogen was E. coli (45.5%). The risk factors increasing the likelihood of E. coli in urine culture were being female, history of urinary tract operation, no use of antibiotics in the preceding three months and infection outside the urinary tract. There were 247 patients with E. coli or Klebsiella spp. positive in culture. Among these, 61% (n=151) were ESBL- positive. Among patients having E. coli/Klebsiella positive in culture, antibiotic use in the preceding three months and history of urinary tract operation were the independent risk factors significantly increasing the risk of ESBL. Conclusions The reasons underlying the high prevalence of nosocomial UTIs, and a better understanding of the risk factors might lead to improved control of these infections. PMID:24188193

    The emergence of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli has become an important challenge among pediatric patients with community-acquired urinary tract infection (UTI). The aim of this study was to assess the antimicrobial susceptibility patterns, associated risk factors and to survey the frequency of bla cefotaximase (CTX-M), bla temoneira (TEM), and bla sulfhydryl variable (SHV) genotypes in ESBL-producing E. coli isolated from children with community-acquired UTI. This was a prospective study conducted from November 2012 to March 2016 in a tertiary care center. E. coli isolated in urine cultures from children aged ≤18 years was identified and confirmed for ESBL production. ESBL-positive strains were screened for ESBL encoding genes. Chi-square test and Fisher's exact test were used to compare the difference in antibiotic susceptibility with respect to ESBL positive and negative, and binary logistic regression was used to identify the risk factors associated with ESBL production. Among 523 E. coli isolates, 196 (37.5%) were ESBL positive, >90% were resistant to cephalosporins, and 56% were resistant to fluoroquinolones. Least resistance was observed for imipenem, netilmicin, and nitrofurantoin (2%, 8.6%, 15.3%). Association between ESBL production and drug resistance was significant for ceftazidime (P community-acquired pediatric UTI carries more than one type of beta-lactamase coding genes correlating their increased antibiotic resistance. Aggressive infection control policy, routine screening for detecting ESBL isolates in clinical samples, and antimicrobial stewardship are the keys to prevent their dissemination in community settings.

    The aim of the present study was to investigate the risk factors of antimicrobial resistance in children with urinary tract infection caused by extended-spectrum beta-lactamase (ESBL)-producing bacteria. A total of 344 patients diagnosed with urinary tract infection (UTI) between January 2008 and December 2009 were enrolled in this retrospective study. Causative microorganisms were ESBL-producing bacteria in 148 patients and non-ESBL-producing bacteria in 196 patients. There was no difference between the two groups regarding distribution of age, sex and length of follow up. The most frequent causative agent was Escherichia coli, of which 41.4% were ESBL producing. Among Klebsiella species, 53.2% were ESBL producing. The proportion of ESBL-producing bacteria that were resistant to antibiotics was 83.1% for trimethoprim/sulfamethoxazole, 18.2% for nitrofurantoin, 47.3% for quinolones, and 39.9% for aminoglycosides. For non-ESBL-producing bacteria, the resistance rate was 62.2% for trimethoprim/sulfamethoxazole, 4.6% for nitrofurantoin, 9.7% for quinolones, and 9.7% for aminoglycosides. Age <1 year, high UTI recurrence rate, long duration of prophylaxis, use of cephalosporins for prophylaxis, hospitalization within the previous 3 months and clean intermittent catheterization were found to be significant risk factors for ESBL-producing bacteria (P < 0.05). Logistic regression analysis identified age <1 year and high recurrence UTI rate to be independent risk factors, increasing the risk 1.74-fold and 2.25-fold, respectively. Recognition of the risk factors for ESBL-producing bacteria may be helpful to determine new policies in the management of UTI. Recurrence of UTI should be prevented especially in the first year of life, and prophylactic cephalosporins should be avoided. © 2012 The Authors.

    Treatment of critical illness on intensive-care-units (ICU) results often in persistent invasive endotracheal intubation which might delay rehabilitation and increases the risk of mortality. Recent longitudinal studies have described the recovery of critically ill people, but the detailed time course of decannulation in patients with chronic critical illness with ICU-acquired muscle weakness (ICUAW) is not well known. The aim of our study was to describe the decannulation times and associated risk factors in patients who are chronic critically ill with ICU acquired weakness. This is a cohort study. Postacute and rehabilitation units. Chronic critically ill patients with ICUAW and tracheostomy tube. We calculated the time until decannulation and used possible predictor variables to explain this time course. We included 122 patients with ICUAW. Successful decannulation of the tracheostomy tube was achieved after a median of 40.5 days (interquartile range= 44) after study onset and after a median of 89 days (interquartile range= 58) after onset of primary illness. Our final multivariate Cox-Proportional Hazard model included two main risk factors for decannulation: the amount of medical tubes such as catheters at admission to the rehabilitation center (adjusted hazard ratio [HR]=1.572 (95% CI: 1.021 to 2.415) and the duration of weaning from respirator in days (adjusted HR= 1.02 per day (95% CI: 1.006 to 1.03). No adverse events occurred. We described the detailed time course of decannulation in the rehabilitation of chronic critically ill patients and no adverse events were observed. Taken many single factors into account the quantity of medical tubes and the duration of weaning from respirator were associated risk factors for decannulation in this population. Knowing an exact time course of decannulation supports medical decisions in clinical rehabilitation and might help to give a prognosis for decannulation. The amount of medical tubes and the duration of weaning

    During outbreaks of hospital-acquired influenza-like illness (HA-ILI) healthcare workers (HCWs), patients, and visitors are each a source of infection for the other. Quantifying the effects of these various exposures will help improve prevention and control of HA-ILI outbreaks. We estimated the attributability of HA-ILI to: (1) exposure to recorded or unrecorded sources; (2) exposure to contagious patient or contagious HCW; (3) exposure during observable or unobservable contagious period of the recorded sources; and, (4) the moment of exposure. Among recorded sources, 59% [95% credible interval (CrI) 34-83] of HA-ILI of patients was associated with exposure to contagious patients and 41% (95% CrI 17-66) with exposure to contagious HCWs. Exposure during the unobservable contagiousness period of source patients accounted for 49% (95% CrI 19-75) of HA-ILI, while exposure during the unobservable contagiousness period of source HCWs accounted for 82% (95% CrI 51-99) of HA-ILI. About 80% of HA-ILIs were associated with exposure 1 day earlier. Secondary cases of HA-ILI might appear as soon as the day after the detection of a primary case highlighting the explosive nature of HA-ILI spread. Unobservable transmission was the main cause of HA-ILI transmission suggesting that symptom-based control measures alone might not prevent hospital outbreaks. The results support the rapid implementation of interventions to control influenza transmission.

    Background: almost 5 million newborns die every year all over the world. 98% of them belong to developing countries. From 30% to 40% of neonatal deaths are related to infections. Objective: to determine risk factors influencing the occurrence of hospital-acquired infections in a neonatology service. Methods: a case-control study was conducted in the Neonatology Service of the Dr. Gustavo Aldereguía Lima General University Hospital of Cienfuegos in 2007. Cases included 76 newborns with hospital-acquired infection and their controls as well as neonates without hospital-acquired infection at a rate of one control per case. The following variables were analyzed: sex, birth weight, age, prenatal medical history, type and duration of labor, use of antibiotics and type of sepsis. Chi-square method was used with a maximum error of 5% and the risk odds ratio was used with a confidence interval of 95%. Results: 42, 1% of those infected were between 1500 g and 2499 g at birth. Infants whose mothers had presented vaginal sepsis had a higher risk for infection (62, 3%, OR = 5.9. Preterm delivery (89, 5%, premature rupture of membrane (22.4%, and instrumentation were potential risks for hospital-acquired infection. Conclusions: Preterm birth, low birth weight, the use of instrumentation and vaginal sepsis in mothers were the main risk factors for the occurrence of hospital-acquired infections in neonates.

    Full Text Available OBJECTIVE: To characterize the 90-day risk of hospitalization with pneumonia among patients treated with different anti-hypertensive drug classes. DESIGN: Population based cohort study using five linked databases. PARTICIPANTS: Individuals over the age of 65 who filled a new outpatient prescription for one of four anti-hypertensive medications: ACE inhibitors (n = 86 775, ARBs (n = 33,953, calcium channel blockers (CCB, n = 34,240, beta blockers (BB, n = 35,331 and thiazide diuretics (n = 64 186. PRIMARY OUTCOME: Hospitalization with pneumonia within 90 days of a qualifying prescription. We adjusted for ten a priori selected covariates, including age, sex, diabetes and number of visits to a family doctor. RESULTS: Baseline characteristics of the groups were relatively well matched, except for age, sex, diabetes and frequency of family doctor visits. 128 of the 86 775 patients (0.15% initiated on an ACE inhibitor and 43 of the 33953 patients (0.13% of patients initiated on an ARB were hospitalized with pneumonia in the subsequent 90 days. 135 of 64 186 patients (0.21% initiated on a thiazide, 112 of 35 331 patients (.32% initiated on a BB, and 89 of 34 240 (0.26% patients initiated on a CCB achieved the primary outcome. Compared to calcium channel blockers, ACE inhibitors (adjusted OR 0.61, 95% CI 0.46 to 0.81 and ARBs (adjusted OR 0.52, 95% CI 0.36 to 0.76 were associated with a lower risk of pneumonia. No benefit was seen with thiazides (adjusted OR 0.87, 95% CI 0.66 to 1.14 or beta blockers (adjusted OR 1.21, 95% CI 0.91 to 1.60. CONCLUSION: Initiating medications that block the renin angiotensin system, compared to other anti-hypertensive medications, is associated with a small absolute reduction in the 90 day risk of hospitalization with pneumonia.

    At the beginning of the 1980-ies, HIV infection and AIDS were described for the first time, this among the population of men who have sex with other men. Nearly thirty years later, the MSM population is still a population under heightened risk for acquiring HIV infection and other sexually transmitted diseases. This study investigates sexually transmitted diseases as a risk for HIV infection. A total of 296 men who have sex with men (MSM) were included in this case control study. Differences among the frequencies of sexually transmitted diseases among the MSM of HIV positive and HIV negative status were tested. The history of HIV positive more often states falling ill with sexually transmitted diseases than this was the case before they became HIV positive, unlike those MSM who are not HIV infected (45.9%:11.1% that is OR 6.79, 95% CI 3.49-13.19). Hepatitis B infection is more frequent in HIV positive MSM (11.5%:1.9%; OR 6.58, 95% CI 1.86-23.3). The frequency of gonorrhea in case history of HIV positive MSM is significantly higher than in the HIV negative group (11.5%:3.8%, OR 3.24, 95% CI 1.13-9.34). In the group of HIV positive MSM, unlike the HIV negative group, syphilis (14.8:1.0%, OR 1774, 95% CI 3.43-122.87) and genital herpes (8.2%:0.5%, OR 18.39, 95% CI 2.03-424.7) are more frequent. The results of this study will be used in future preventive activities focused on the population of MSM, as a population under particular risk for acquiring sexually transmitted infections.

    PROBLEM  The purpose of this study was to determine whether quantification of peripheral blood Treg cell levels could be used as an indicator of miscarriage risk in newly pregnant women with a history of immunologic reproductive failure. METHOD OF STUDY  Fifty-four pregnant women with a history of immunologic infertility and/or pregnancy loss were retrospectively evaluated (mean age: 36.7 ± 4.9 years, 2.8 ± 2.5 previous miscarriages; 1.5 ± 1.9 previous IVF failures). Twenty-three of these women experienced another first trimester miscarriage, and 31 of these women continued their current pregnancies past 12 weeks ('pregnancy success'). The following immunologic parameters were assessed in the first trimester: NK cell 50:1 cytotoxicity, CD56(+)  16(+)  CD3(-) (NK), CD56(+)  CD3(+) (NKT), TNFα/IL-10, IFNγ/IL-10, CD4(+)  CD25(-) Foxp3(+) , total CD4(+)  Foxp3(+) (CD4(+ ) CD25(+)  Foxp3 plus CD25(- ) Foxp3(+) ), and CD4(+)  CD25(+)  Foxp3(+) levels. RESULTS  Patients with successful ongoing pregnancies experienced a mean (CD4(+)  CD25(+)  Foxp3(+) ) 'Treg' level of 0.72 ± 0.52%, while those that miscarried in the first trimester experienced a mean Treg level of 0.37 ± 0.29% (P = 0.005). Markers not significantly different between the loss and success groups were NK 50:1 cytotoxicity (P = 0.63), CD56(+)  16(+)  3(+) NK cells (P = 0.63), CD56(+)  3(+)   NKT (P = 0.30), TNFα(+) IL-10(+) (P = 0.13), IFNg(+) IL-10(+) (P = 0.63), and CD4(+)  25(-)  Foxp3(+) cells (P = 0.10), although total CD4(+)  Foxp3(+) levels remained significant (P = 0.02) and CD4(+)  25(+) Foxp3(+) showed the most significant difference (P = 0.005). Mean day of blood draw was 49.2 ± 36.1 days pregnant (median 39.0 days). In addition, patients with a low Treg level (0.7%) in the first trimester [44% (15/34) versus 80% (16/20); P = 0.01].

    Background: Elderly multiple myeloma (MM) patients often tend to suffer a variety of diseases, so the treatment of choice is very difficult for the elderly myeloma patients. The overall survival (OS) time and side effects with elderly patients are unclear in China. The study tried to find out the role of geriatric assessment in the Chinese elderly MM. Methods: We retrospectively analyzed the data of 628 newly diagnosed patients from six hospitals from June 2011 to June 2013. A geriatric assessment had been performed to assess comorbidities, cognitive, and physical status for these patients. The primary endpoint was to evaluate different physical states of elderly patients with OS time and treatment-related side effects. Results: An additive scoring system (range: 0–5), based on age, Katz's Activity of Daily Living (ADL) and Lawton's Instrumental Activity of Daily Living (IADL) ≤5 and Charlson Comorbidity Index (CCI) was developed to identify three groups: fit (score = 0); intermediate-fitness (score = 1); and frail (score ≥2). The 3-year OS was 63% in fit patients, 63% in intermediate-fitness patients, and 49% in frail patients ≥3 hematologic adverse events (AEs) were documented in 45 (35.4%) fit, 34 (34%) intermediate-fitness, and 121 (30.2%) frail patients. The risk of a grade ≥3 hematologic AEs was not significantly increase in intermediate-fitness (hazard ratios [HR]: 0.99, 95% confidence interval [CI]: 0.54–1.47, P = 1.000) and in frail patients (HR: 1.16, 95% CI: 0.70–1.93, P = 0.558) compared with fit ones. Conclusions: MM occurs earlier in life and being advanced when the diagnosis is made in the mainland of China. The overall survival in frailty with International Staging System (ISS) II/III was the worst in all patients. PMID:28091402

    Full Text Available Community-acquired MRSA (CA-MRSA is rapidly increasing. Currently, it is unknown which reservoirs are involved. An exploratory hospital-based case-control study was performed in sixteen Dutch hospitals to identify risk factors for CA-MRSA carriage in patients not belonging to established risk groups.Cases were in- or outpatients from sixteen Dutch hospitals, colonised or infected with MRSA without healthcare- or livestock-associated risk factors for MRSA carriage. Control subjects were patients not carrying MRSA, and hospitalised on the same ward or visited the same outpatients' clinic as the case. The presence of potential risk factors for CA-MRSA carriage was determined using a standardised questionnaire.Regular consumption of poultry (OR 2⋅40; 95% CI 1⋅08-5⋅33, cattle density per municipality (OR 1⋅30; 95% CI 1⋅00-1⋅70, and sharing of scuba diving equipment (OR 2⋅93 95% CI 1⋅19-7⋅21 were found to be independently associated with CA-MRSA carriage. CA-MRSA carriage was not related to being of foreign origin.The observed association between the consumption of poultry and CA-MRSA carriage suggests that MRSA in the food chain may be a source for MRSA carriage in humans. Although sharing of scuba diving equipment was found to be associated with CA-MRSA carriage, the role played by skin abrasions in divers, the lack of decontamination of diving materials, or the favourable high salt content of sea water is currently unclear. The risk for MRSA MC398 carriage in areas with a high cattle density may be due to environmental contamination with MRSA MC398 or human-to-human transmission. Further studies are warranted to confirm our findings and to determine the absolute risks of MRSA acquisition associated with the factors identified.

    Full Text Available Campylobacteriosis is the most frequently reported food- and waterborne infection in Norway. We investigated the risk factors for sporadic Campylobacter infections in Norway in order to identify areas where control and prevention measures could be improved.A national prospective case-control study of factors associated with Campylobacter infection was conducted from July 2010 to September 2011. Cases were recruited from the Norwegian Surveillance System of Communicable Diseases (MSIS. Controls were randomly selected from the Norwegian Population Registry. Cases and controls were mailed a paper questionnaire with a prepaid return envelope. Univariable analyses using logistic regression were conducted for all exposures. A final parsimonious multivariable model was developed using regularized/penalized logistic regression, and adjusted odds ratios were calculated.A total of 995 cases and 1501 controls were included in the study (response proportion 55% and 30%, respectively. Exposures that had significant increases in odds of Campylobacter infection in multivariable analysis were drinking water directly from river, stream, or lake (OR: 2.96, drinking purchased bottled water (OR: 1.78, eating chicken (1.69, eating meat that was undercooked (OR: 1.77, eating food made on a barbecue (OR: 1.55, living on a farm with livestock (OR: 1.74, having a dog in the household (OR: 1.39, and having household water supply serving fewer than 20 houses (OR: 1.92.Consumption of poultry and untreated water remain important sources of Campylobacter infection in Norway, despite ongoing control efforts. The results justify the need for strengthening education for consumers and food handlers about the risks of cross-contamination when preparing poultry and with consuming raw or undercooked chicken. The public should also be reminded to take precautions when drinking untreated water in nature and ensure continued vigilance in order to protect and maintain the quality of

    More than 600,000 football fans, coming from all over the world, were expected to visit Brazil during the FIFA World Cup 2014. International travel can become a public health problem when the visitors start to become sick, needing medical intervention and eventually hospitalization. The occurrence of dengue fever infections in Brazil is persistent and has been increasing since the 1980s, and the health authorities were expected to take preventive measures and to warn the visitors about the risks during the tournament period. Before the World Cup started, studies have been published stating that dengue could be a significant problem in some of the Brazilian cities hosting the games. These conclusions were taken after a brief observation of the available data, analyzing its mean and standard deviation only, or based on seasonal climate forecasts, causing alarm for the world cup in Brazil. Here, with a more careful data analysis, we show that the seasonality of the disease plays a major role in dengue transmission. The density of dengue cases in Brazil is residual during winter in the Southern hemisphere (mid June to mid September) and the fans of football were not likely to get dengue during the tournament period.

    Full Text Available The objective of this study was to determine the prevalence of pAmpC beta-lactamases in community-acquired Gram negative bacteria in the Netherlands, and to identify possible risk factors for carriage of these strains.Fecal samples were obtained from community-dwelling volunteers. Participants also returned a questionnaire for analysis of risk factors. Screening for pAmpC was performed with selective enrichment broth and a selective screening agar. Confirmation of AmpC-production was performed with two double disc combination tests: cefotaxime and ceftazidime with either boronic acid or cloxacillin as inhibitor. Multiplex PCR was used as gold standard for detection of pAmpC. 16S rRNA PCR and AFLP were performed as required, plasmids were identified by PCR-based replicon typing. Questionnaire results were analyzed with SPSS, version 20.0.Fecal samples were obtained from 550 volunteers; mean age 51 years (range: 18-91, 61% were females. pAmpC was present in seven E. coli isolates (7/550, 1.3%, 0.6-2.7 95% CI: six CMY-2-like pAmpC and one DHA. ESBL-encoding genes were found in 52/550 (9.5%, 7.3-12.2 95% CI isolates; these were predominantly blaCTX-M genes. Two isolates had both ESBL and pAmpC. Admission to a hospital in the previous year was the only risk factor we identified.Our data indicate that the prevalence of pAmpC in the community seems still low. However, since pAmpC-producing isolates were not identified as ESBL producers by routine algorithms, there is consistent risk that further increase of their prevalence might go undetected.

    Little is known about the prognosis of community-acquired bacteraemia (CAB) in workforce adults. We assessed return to workforce, risk for sick leave, disability pension and mortality within 1 year after CAB in workforce adults compared with blood culture-negative controls and population controls. Population-based cohort study. North Denmark, 1996-2011. We used population-based healthcare registries to identify all patients aged 20-58 years who had first-time blood cultures obtained within 48 h of medical hospital admission, and who were part of the workforce (450 bacteraemia exposed patients and 6936 culture-negative control patients). For each bacteraemia patient, we included up to 10 matched population controls. Return to workforce, risk of sick leave, permanent disability pension and mortality within 1 year after bacteraemia. Regression analyses were used to compute adjusted relative risks (RRs) with 95% CIs. One year after admission, 78% of patients with CAB, 85.7% of culture-negative controls and 96.8% of population controls were alive and in the workforce, and free from sick leave or disability pension. Compared with culture-negative controls, bacteraemia was associated with an increased risk for long-term sick leave (4-week duration, 40.2% vs 23.9%, adjusted RR, 1.51; CI 1.34 to 1.70) and an increased risk for mortality (30-day mortality, 4% vs 1.4%, adjusted RR, 2.34, CI 1.22 to 4.50; 1-year mortality, 8% vs 3.9%, adjusted RR, 1.73; CI 1.18 to 2.55). Bacteraemia patients had a risk for disability pension similar to culture-negative controls (2.7% vs 2.6%, adjusted RR, 0.99, CI 0.48 to 2.02) but greater than population controls (adjusted RR, 5.20; 95% CI 2.16 to 12.50). CAB is associated with long duration of sick leave and considerable mortality in working-age adults when compared with blood culture-negative controls, and an increased 1-year risk for disability pension when compared with population controls.

The survey includes acute care (91.4%), long-term acute care (1.7%), rehabilitation patients (1.7%) and long-term care residents (5.2%). Geographic distribution included 182,832 patients in the United States, 22,282 patients in Canada, and the rest of the world, primarily in Europe and the Middle East. We analyzed data from the 2013 and 2014 IPUP surveys to better understand the relationship between incontinence and the frequency and severity of FAPUs. The IPUP survey is an annual voluntary survey of patients who are hospitalized or who reside in long-term care facilities. Data were collected over a 24-hour period within each participating facility. Data collection included limited demographics, presence and stage of pressure ulcers, and pressure ulcer risk assessment score (Braden Scale for Pressure Sore Risk, Braden Q, Norton, Waterlow, and others). In addition, data were collected on pertinent pressure ulcer risk factors including the number of linen layers, use of a pressure redistributing surface, adherence to repositioning schedule, and whether moisture management was provided in the last 24 hours. We aggregated data by urinary, urinary catheter, fecal, fecal management system, double (urinary and fecal), and ostomy incontinence category. If patients were managed by indwelling urinary catheter or fecal management systems, they were considered incontinent in this analysis. In order to analyze ulcers likely to be affected by incontinence, we defined a subset of ulcers as Relevant Pressure Ulcers, which are ulcers that are facility-acquired, non

    Full Text Available Questionnaires are popular and fundamental tools for acquiring information on public knowledge and perception of natural hazards. Questionnaires can provide valuable information to emergency management agencies for developing risk management procedures. Although many natural hazards researchers describe results generated from questionnaires, few explain the techniques used for their development and implementation. Methodological detail should include, as a minimum, response format (open/closed questions, mode of delivery, sampling technique, response rate and access to the questionnaire to allow reproduction of or comparison with similar studies. This article reviews current knowledge and practice for developing and implementing questionnaires. Key features include questionnaire design, delivery mode, sampling techniques and data analysis. In order to illustrate these aspects, a case study examines methods chosen for the development and implementation of questionnaires used to obtain information on knowledge and perception of volcanic hazards in a tourist region in southern Iceland. Face-to-face interviews highlighted certain issues with respect to question structure and sequence. Recommendations are made to overcome these problems before the questionnaires are applied in future research projects. In conclusion, basic steps that should be disclosed in the literature are provided as a checklist to ensure that reliable, replicable and valid results are produced from questionnaire based hazard knowledge and risk perception research.

    Tyrothricin, an antimicrobial peptide combination produced by Bacillus brevis consisting of gramicidins and tyrocidins commands broad antimicrobial activity against gram-positive bacteria and some yeasts in vitro. The polypeptide and its components have been used therapeutically for about 60 years in the local treatment of infected skin and infected oro-pharyngeal mucous membranes. Though older studies suggest that resistance development of originally susceptible microorganisms towards tyrothricin is a rare event, data concerning recent state of resistance are lacking. In the present in vitro study the susceptibility to tyrothricin of clinical isolates of bacterial and yeast origin from superficial swabs of the skin and mucous membranes of outpatients and inpatients obtained from clinical material in the second half of the year 2003 was determined. Using a microdilution assay, the minimum inhibitory concentration (MIC and MIC90, defined as the concentration that inhibits at least 90 percent of the tested strains) of 20 strains each of Staphylococcus aureus of the variety MSSA (susceptible to methicillin), Staphylococcus aureus of the variety MRSA (methicillin resistant), Staphylococcus haemolyticus, Streptococcus pyogenes, Enterococcus faecalis, Corynebacterium spec., Candida albicans and Candida parapsilosis was determined. All of the tested gram-positive bacteria turned out to be highly susceptible to tyrothricin with MICs ≤ 4mg/l. The tested yeast strains were susceptible to the polypeptide antibiotic as well, but (with MICs of 16 mg/l and 32 mg/l, respectively) to a lesser extent. No acquired resistance of the tested strains was determined, indicating that the risk of resistance development against topically applied tyrothricin is only marginal, if there is any at all. Thus, long-term-, i.e. decade-long use of topically applied tyrothricin and its components in the local treatment of infected skin does not pose a major risk with respect to acquired resistance

    Full Text Available Objective: This study aimed to determine the etiologic factors of acquired methemoglobinemia in infants younger than three months in our region. Material and Methods: This study was carried out retrospectively in infants with methemoglobinemia admitted to Karadeniz Technical University, Pediatric Clinic, during the period 2000-2009. Infants with methemoglobinemia were identified according to the medical records or ICD-10 code. Results: Nine infants with acquired methemoglobinemia (8 male, 1 female were included in the study. Seven cases were associated with the use of prilocaine for circumcision, one case with the use of prilocaine-lidocaine for local pain therapy, and one case with neonatal sepsis caused by Staphylococcus aureus.Conclusion: Prilocaine should not be used in infants less than three months of age because of the risk of methemoglobinemia. Ascorbic acid is an effective therapy if methylene blue is not obtained. It should not be forgotten that sepsis caused by S. aureus may cause methemoglobinemia in infants.

    Full Text Available Context: Hospital-acquired hypernatremia (HAH is a frequent concern in critical care, which carries high mortality. Aims: To study the risk factors for HAH in settings that practice a preventive protocol. Settings and Design: Two tertiary-care hospitals. Prospective observational study design. Materials and Methods: Patients aged >18 years admitted for an acute medical illness with normal serum sodium and need for intensive care >48 h formed the study population. Details of the basic panel of investigations on admission, daily electrolytes and renal function test, sodium content of all intake, free water intake (oral, enteral and intravenous and fluid balance every 24 h were recorded. Individuals with serum Na 140-142 meq/l received 500 ml of free water every 24 h, and those with 143-145 meq/l received 1000 ml free water every 24 h. Statistical Analysis Used: Risk factors associated with HAH was analysed by multiple logistic regression. Results: Among 670 study participants, 64 (9.5% developed HAH. The median duration of hypernatremia was 3 days. A total 60 of 64 participants with HAH had features of renal concentrating defect during hypernatremia. Age >60 years ( P = 0.02, acute kidney injury (AKI on admission ( P = 0.01, mechanical ventilation ( P = 0.01, need for ionotropes ( P = 0.03, worsening Sequential Organ Failure Assessment (SOFA score after admission ( P < 0.001, enteral tube feeds ( P = 0.002, negative fluid balance ( P = 0.02 and mannitol use ( P < 0.001 were the risk factors for HAH. Mortality rate was 34.3% among hypernatremic patients. Conclusions: The study suggests that administration of free water to prevent HAH should be more meticulously complied with in patients who are elderly, present with AKI, suffer multi-organ dysfunction, require mechanical ventilation, receive enteral feeds and drugs like mannitol or ionotropes.

    Full Text Available Contributors to long-term mortality in patients with community-acquired pneumonia (CAP remain unclear, with little attention paid to pneumonia etiology. We examined long-term survival, causes of death, and risk factors for long-term mortality in adult patients who had been hospitalized for CAP, with emphasis on demographic, clinical, laboratory, and microbiological characteristics.Two hundred and sixty-seven consecutive patients admitted in 2008-2011 to a general hospital with CAP were prospectively recruited and followed up. Patients who died during hospital stay were excluded. Demographic, clinical, and laboratory data were collected within 48 hours of admission. Extensive microbiological work-up was performed to establish the etiology of CAP in 63% of patients. Mortality data were obtained from the Norwegian Cause of Death Registry. Cox regression models were used to identify independent risk factors for all-cause mortality.Of 259 hospital survivors of CAP (median age 66 years, 79 (30.5% died over a median of 1,804 days (range 1-2,520 days. Cumulative 5-year survival rate was 72.9% (95% CI 67.4-78.4%. Standardized mortality ratio was 2.90 for men and 2.05 for women. The main causes of death were chronic obstructive pulmonary disease (COPD, vascular diseases, and malignancy. Independent risk factors for death were the following (hazard ratio, 95% CI: age (1.83 per decade, 1.47-2.28, cardiovascular disease (2.63, 1.61-4.32, COPD (2.09, 1.27-3.45, immunocompromization (1.98, 1.17-3.37, and low serum albumin level at admission (0.75 per 5 g/L higher, 0.58-0.96, whereas active smoking was protective (0.32, 0.14-0.74; active smokers were younger than non-smokers (P < 0.001. Microbial etiology did not predict mortality.Results largely confirm substantial comorbidity-related 5-year mortality after hospitalization for CAP and the impact of several well-known risk factors for death, and extend previous findings on the prognostic value of serum albumin

    Full Text Available Community-acquired urinary tract infection (CA-UTI is the most common infection caused by extended-spectrum β-lactamase (ESBL-producing Enterobacteriaceae, but the clinical epidemiology of these infections in low prevalence countries is largely unknown. A population based case-control study was conducted to assess risk factors for CA-UTI caused by ESBL-producing E. coli or K. pneumoniae. The study was carried out in a source population in Eastern Norway, a country with a low prevalence of infections caused by ESBL-producing Enterobacteriaceae. The study population comprised 100 cases and 190 controls with CA-UTI caused by ESBL-producing and non-ESBL-producing E. coli or K. pneumoniae, respectively. The following independent risk factors of ESBL-positive UTIs were identified: Travel to Asia, The Middle East or Africa either during the past six weeks (Odds ratio (OR = 21; 95% confidence interval (CI: 4.5-97 or during the past 6 weeks to 24 months (OR = 2.3; 95% CI: 1.1-4.4, recent use of fluoroquinolones (OR = 16; 95% CI: 3.2-80 and β-lactams (except mecillinam (OR = 5.0; 95% CI: 2.1-12, diabetes mellitus (OR = 3.2; 95% CI: 1.0-11 and recreational freshwater swimming the past year (OR = 2.1; 95% CI: 1.0-4.0. Factors associated with decreased risk were increasing number of fish meals per week (OR = 0.68 per fish meal; 95% CI: 0.51-0.90 and age (OR = 0.89 per 5 year increase; 95% CI: 0.82-0.97. In conclusion, we have identified risk factors that elucidate mechanisms and routes for dissemination of ESBL-producing Enterobacteriaceae in a low prevalence country, which can be used to guide appropriate treatment of CA-UTI and targeted infection control measures.

    Antimicrobial resistance to ciprofloxacin is rising worldwide, especially in bacteria causing urinary tract infections (UTIs). Prudent use of current antibiotic drugs is therefore necessary. We analysed (modifiable) risk factors for ciprofloxacin-resistant Escherichia coli. Urinary cultures of UTIs caused by E. coli were collected from participants in the Rotterdam Study, a prospective cohort study in an elderly population, and analysed for susceptibility to ciprofloxacin. Multivariate logistic regression was performed to investigate several possible risk factors for resistance. Ciprofloxacin resistance in 1080 E. coli isolates was 10.2%. Multivariate analysis showed that higher age (OR 1.03; 95% CI 1.00-1.05) and use of two (OR 5.89; 95% CI 3.45-10.03) and three or more (OR 3.38; 95% CI 1.92-5.97) prescriptions of fluoroquinolones were associated with ciprofloxacin resistance, while no association between fluoroquinolone use more than 1 year before culture and ciprofloxacin resistance could be demonstrated. Furthermore, a high intake of pork (OR 3.68; 95% CI 1.36-9.99) and chicken (OR 2.72; 95% CI 1.08-6.85) and concomitant prescription of calcium supplements (OR 2.51; 95% CI 1.20-5.22) and proton pump inhibitors (OR 2.04; 95% CI 1.18-3.51) were associated with ciprofloxacin resistance. Ciprofloxacin resistance in community-acquired UTI was associated with a high intake of pork and chicken and with concomitant prescription of calcium supplements and proton pump inhibitors. Modification of antibiotic use in animals as well as temporarily stopping the prescription of concomitant calcium and proton pump inhibitors need further evaluation as strategies to prevent ciprofloxacin resistance. © The Author 2016.

    Full Text Available BACKGROUND: The number of extended-spectrum beta-lactamase (ESBL positive (+ Escherichia coli is increasing worldwide. In contrast with many other multidrug-resistant bacteria, it is suspected that they predominantly spread within the community. The objective of this study was to assess factors associated with community-acquired colonization of ESBL (+ E. coli. METHODS: We performed a matched case-control study at the Charité University Hospital Berlin between May 2011 and January 2012. Cases were defined as patients colonized with community-acquired ESBL (+ E. coli identified <72 h after hospital admission. Controls were patients that carried no ESBL-positive bacteria but an ESBL-negative E.coli identified <72 h after hospital admission. Two controls per case were chosen from potential controls according to admission date. Case and control patients completed a questionnaire assessing nutritional habits, travel habits, household situation and language most commonly spoken at home (mother tongue. An additional rectal swab was obtained together with the questionnaire to verify colonization status. Genotypes of ESBL (+ E. coli strains were determined by PCR and sequencing. Risk factors associated with ESBL (+ E. coli colonization were analyzed by a multivariable conditional logistic regression analysis. RESULTS: We analyzed 85 cases and 170 controls, respectively. In the multivariable analysis, speaking an Asian language most commonly at home (OR = 13.4, CI 95% 3.3-53.8; p<0.001 and frequently eating pork (≥ 3 meals per week showed to be independently associated with ESBL colonization (OR = 3.5, CI 95% 1.8-6.6; p<0.001. The most common ESBL genotypes were CTX-M-1 with 44% (n = 37, CTX-M-15 with 28% (n = 24 and CTX-M-14 with 13% (n = 11. CONCLUSION: An Asian mother tongue and frequently consuming certain types of meat like pork can be independently associated with the colonization of ESBL-positive bacteria. We found neither frequent consumption

    Travel to (sub)tropical countries is a well-known risk factor for acquiring resistant bacterial strains, which is especially of significance for travellers from countries with low resistance rates. In this study we investigated the rate of and risk factors for travel-related acquisition of extended spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E), ciprofloxacin-resistant Enterobacteriaceae (CIPR-E) and carbapenem-resistant Enterobacteriaceae. Data before and after travel were collected from 445 participants. Swabs were cultured with an enrichment broth and sub-cultured on selective agar plates for ESBL detection, and on plates with a ciprofloxacin disc. ESBL production was confirmed with the double-disc synergy test. Species identification and susceptibility testing were performed with the Vitek-2 system. All isolates were subjected to ertapenem Etest. ESBL and carbapenemase genes were characterized by PCR and sequencing. Twenty-seven out of 445 travellers (6.1%) already had ESBL-producing strains and 45 of 445 (10.1%) travellers had strains resistant to ciprofloxacin before travel. Ninety-eight out of 418 (23.4%) travellers acquired ESBL-E and 130 of 400 (32.5%) travellers acquired a ciprofloxacin-resistant strain. Of the 98 ESBL-E, predominantly Escherichia coli and predominantly blaCTX-M-15, 56% (55/98) were resistant to gentamicin, ciprofloxacin and co-trimoxazole. Multivariate analysis showed that Asia was a high-risk area for ESBL-E as well as CIPR-E acquisition. Travellers with diarrhoea combined with antimicrobial use were significantly at higher risk for acquisition of resistant strains. Only one carbapenemase-producing isolate was acquired, isolated from a participant after visiting Egypt. In conclusion, travelling to Asia and diarrhoea combined with antimicrobial use are important risk factors for acquiring ESBL-E and CIPR-E.

    This study explored the prevalence of risk behaviors (excessive alcohol use, illegal drug use, heavy smoking, reduced sleep, overweight, underweight, sedentary behavior, high use of Internet/TV/videogames for reasons not related to school or work, and truancy), and their association with psychopathology and self-destructive behaviors, in a sample of 12,395 adolescents recruited in randomly selected schools across 11 European countries. Latent class analysis identified three groups of adolescents: a low-risk group (57.8%) including pupils with low or very low frequency of risk behaviors; a high-risk group (13.2%) including pupils who scored high on all risk behaviors, and a third group (“invisible” risk, 29%) including pupils who were positive for high use of Internet/TV/videogames for reasons not related to school or work, sedentary behavior and reduced sleep. Pupils in the “invisible” risk group, compared with the high-risk group, had a similar prevalence of suicidal thoughts (42.2% vs. 44%), anxiety (8% vs. 9.2%), subthreshold depression (33.2% vs. 34%) and depression (13.4% vs. 14.7%). The prevalence of suicide attempts was 5.9% in the “invisible” group, 10.1% in the high-risk group and 1.7% in the low-risk group. The prevalence of all risk behaviors increased with age and most of them were significantly more frequent among boys. Girls were significantly more likely to experience internalizing (emotional) psychiatric symptoms. The “invisible” group may represent an important new intervention target group for potentially reducing psychopathology and other untoward outcomes in adolescence, including suicidal behavior.

    The interpersonal psychological theory of suicide provides a useful framework for considering the relationship between non-suicidal self-injury and suicide. Researchers propose that NSSI increases acquired capability for suicide. We predicted that both NSSI frequency and the IPTS acquired capability construct (decreased fear of death and increased pain tolerance) would separately interact with suicidal ideation to predict suicide attempts. Undergraduate students (N = 113) completed self-report questionnaires, and a subsample (n = 66) also completed a pain sensitivity task. NSSI frequency significantly moderated the association between suicidal ideation and suicide attempts. However, in a separate model, acquired capability did not moderate this relationship. Our understanding of the relationship between suicidal ideation and suicidal behavior can be enhanced by factors associated with NSSI that are distinct from the acquired capability construct.

METHODS By the means of retrospective survey, the related factors for hospital-acquired pneumonia in 368 patients in NICU were analyzed. RESULTS The incidence of hospital-acquired pneumonia in NICU was 10. 33% ; the age of the patient,underlying disease, consciousness, length of hospital stay, the space for each bed, and the invasive operations like tracheotomy were the risk factors which were closely related to hospital-acquired pneumonia. CONCLUSION To reduce the risk factors for hospital-acquired pneumonia is essential and effective to reduce the incidence of hospital-acquired pneumonia.

  6. Which individuals are at increased risk of pneumococcal disease and why? Impact of COPD, asthma, smoking, diabetes, and/or chronic heart disease on community-acquired pneumonia and invasive pneumococcal disease.

    2015-10-01

    Pneumococcal disease (including community-acquired pneumonia and invasive pneumococcal disease) poses a burden to the community all year round, especially in those with chronic underlying conditions. Individuals with COPD, asthma or who smoke, and those with chronic heart disease or diabetes mellitus have been shown to be at increased risk of pneumococcal disease compared with those without these risk factors. These conditions, and smoking, can also adversely affect patient outcomes, including short-term and long-term mortality rates, following pneumonia. Community-acquired pneumonia, and in particular pneumococcal pneumonia, is associated with a significant economic burden, especially in those who are hospitalised, and also has an impact on a patient's quality of life. Therefore, physicians should target individuals with COPD, asthma, heart disease or diabetes mellitus, and those who smoke, for pneumococcal vaccination at the earliest opportunity at any time of the year.

    2015-09-27

    Japanese encephalitis (JE) is a serious arboviral disease caused by a virus of the genus Flavivirus. Japanese encephalitis is the most common vaccine-preventable virus causing encephalitis in Asia, affecting more than 50,000 persons and leading to 15,000 fatalities per year in endemic countries. For most travelers to Asia, the risk of Japanese encephalitis infection is extremely low and depends on destination, duration of travel, season, and activities. This article reviews travel-acquired Japanese encephalitis with a focus on epidemiology and prevention in the light of the newly available options for active immunization against Japanese encephalitis which have become available, and of the increasing popularity of travels to Japanese encephalitis endemic countries.

    Development of hepatocellular carcinoma (HCC) is a multi-factorial process. Chronic infections with hepatitis B virus (HBV) and hepatitis C virus (HCV) are important risk factors of HCC. Host factors, such as alcohol drinking, may also play a role. This study aims to provide a synthesis view on the development of HCC by examining multiple risk factors jointly and collectively. Causal-pie modeling technique was applied to analyze a cohort of 11,801 male residents (followed up for 15 years) in Taiwan, during which a total of 298 incident HCC cases were ascertained. The rate ratios adjusted by age were further modeled by an additive Poisson regression. Population attributable fractions (PAFs) and causal-pie weights (CPWs) were calculated. A PAF indicates the magnitude of case-load reduction under a particular intervention scenario, whereas a CPW for a particular class of causal pies represents the proportion of HCC cases attributable to that class. Using PAF we observed a chance to reduce around 60% HCC risk moving from no HBV-related intervention to the total elimination of the virus. An additional ∼15% (or ∼5%) reduction can be expected, if the HBV-related intervention is coupled with an HCV-related intervention (or an anti-drinking campaign). Eight classes of causal pies were found to be significant, including four dose-response classes of HBV (total CPW=52.7%), one independent-effect class of HCV (CPW=14.4%), one HBV-alcohol interaction class (CPW=4.2%), one HBV-HCV interaction class (CPW=1.7%), and one all-unknown class (CPW=27.0%). Causal-pie modeling for HCC helps clarify the relative importance of each viral and host factor, as well as their interactions.

    We assessed the prospective association between baseline serum uric acid levels and consequent risk of developing diabetic retinopathy. Data for 1839 type 2 diabetes patients without diabetic retinopathy were obtained from a Japanese diabetes registry. A Cox proportional hazards model with time-varying exposure information by sex was used and adjusted for potential confounders to assess the independent correlations between baseline serum uric acid levels and incidence rate of diabetic retinopathy. Newly developed diabetic retinopathy was recognized in 188 patients (10.2%) during the observation period of 2 years. Compared to the first serum uric acid quartile level, the multivariate adjusted hazards ratio for diabetic retinopathy development in male patients was 1.97 (95% CI, 1.14-3.41; P = .015), 1.92 (95% CI, 1.18-3.13; P = .008), and 2.17 (95% CI, 1.40-3.37; P = .001) for the second, third, and fourth serum uric acid quartile levels, respectively. But this was not the case with female patients. Higher serum uric acid levels were associated with increased risk of developing diabetic retinopathy in male patients with type 2 diabetes, but not in female patients. Serum uric acid may be a useful biomarker for predicting the future risk of developing diabetic retinopathy in male patients with type 2 diabetes. Copyright © 2017 John Wiley & Sons, Ltd.

  13. ICU-Acquired Weakness.

    2016-11-01

    Survivorship after critical illness is an increasingly important health-care concern as ICU use continues to increase while ICU mortality is decreasing. Survivors of critical illness experience marked disability and impairments in physical and cognitive function that persist for years after their initial ICU stay. Newfound impairment is associated with increased health-care costs and use, reductions in health-related quality of life, and prolonged unemployment. Weakness, critical illness neuropathy and/or myopathy, and muscle atrophy are common in patients who are critically ill, with up to 80% of patients admitted to the ICU developing some form of neuromuscular dysfunction. ICU-acquired weakness (ICUAW) is associated with longer durations of mechanical ventilation and hospitalization, along with greater functional impairment for survivors. Although there is increasing recognition of ICUAW as a clinical entity, significant knowledge gaps exist concerning identifying patients at high risk for its development and understanding its role in long-term outcomes after critical illness. This review addresses the epidemiologic and pathophysiologic aspects of ICUAW; highlights the diagnostic challenges associated with its diagnosis in patients who are critically ill; and proposes, to our knowledge, a novel strategy for identifying ICUAW.

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

    Lenalidomide is an immunomodulatory compound with high clinical activity in multiple myeloma. Lenalidomide binding to the Cereblon (CRBN) E3 ubiquitin ligase results in targeted ubiquitination and degradation of the lymphoid transcription factors Ikaros (IKZF1) and Aiolos (IKZF3) leading to growth inhibition of multiple myeloma cells. Recently, Basigin (BSG) was identified as another protein regulated by CRBN that is involved in the activity of lenalidomide. Here, we analyzed the prognostic value of IKZF1, IKZF3, CRBN and BSG mRNA expression levels in pretreatment plasma cells from 60 patients with newly diagnosed multiple myeloma uniformly treated with lenalidomide in combination with intensive chemotherapy within a clinical trial. We found that IKZF1 mRNA expression levels are significantly associated with progression-free survival (PFS). Patients in the lowest quartile (Q1) of IKZF1 expression had a superior PFS compared with patients in the remaining quartiles (Q2-Q4; 3-year PFS of 86 vs 51%, P=0.01). This translated into a significant better overall survival (100 vs 74%, P=0.03). Subgroup analysis revealed a significant impact of IKZF1, IKZF3 and BSG expression levels on PFS in cytogenetically defined standard-risk but not high-risk patients. Our data suggest a prognostic role of IKZF1, IKZF3 and BSG expression levels in lenalidomide-treated multiple myeloma.Leukemia advance online publication, 20 January 2017; doi:10.1038/leu.2016.384.

    Objective: To investigate the cardiovascular disease risk of the newly diagnosed adult latent autoimmune diabetes ( LADA) . Methods: After determination of diabetes autoantibodies ,132 cases newly diagnosed diabetes were divided into LADA group (n = 60) and type 2 diabetes mellitus (T2DM) group (n =72) . At the same time,46 cases from physical examination center were selected in normal controls group (NC group) , whoes age and body mass index matched with LADA group. The high-sensitivity C-reac-tive protein ( hs-CRP) level and the carotid intima medial thickness ( CIMT) in three groups were compared. Results: 1. The concentration of hs-CRP and the levels of CIMT in the LADA group was significantly higher than NC group, (P0. 05) , also were between LADA without AS group and T2DM without AS group(P >0. 05) . There were no statistical significance between LADA group and T2DM group in the incidence of AS and carotid atherosclerosis plaque(P = 0. 489, P = 0. 920) , the proportion of moderate risk group and high risk group of cardiovascular disease between two group were also no significant difference ( P > 0.05, P>0.05). 3. In LAD A group, LDL-C, FPG, HbAlc, 2hPG, hs-CRP showed a significant linear correlation with CIMT(P = 0. 001-0. 044) . Conclusion: The elevated hs-CRP levels and CIMT levels in newly diagnosed LADA indicated that its risk of cardiovascular disease was increased. The hs-CRP and CIMT levels in newly diagnosed LADA and newly diagnosed T2DM was no significant difference .%目的:临床评估初诊成人隐匿性自身免疫糖尿病(Latent autoimmune diabetes in adults,LADA)心血管疾病风险.方法:初诊糖尿病(Diabetes mellitus,DM)患者,共132例,经糖尿病自身抗体检测后分为LADA组和2型糖尿病(Type 2 diabetes mellitus,T2DM)组(其中LADA组60例,T2DM组72例).同时从体检中心选取与LADA组年龄、体重指数相匹配的健康对照(Normal controls,NC)组46例.观察高敏C反应蛋白(High-sensitivity C-reactive protein

    The acquired demyelinating neuropathies can be divided into those with an acute onset and course and those with a more chronic course. The acute neuropathies present as Guillain-Barré syndrome and include acute inflammatory demyelinating polyradiculoneuropathy (AIDP), Miller Fisher syndrome, acute motor axonal neuropathy (AMAN), acute motor and sensory axonal neuropathy (AMSAN), and acute pandysautonomia. The chronic neuropathies are collectively known as chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and include MADSAM (multifocal acquired demyelinating sensory and motor neuropathy, also know as Lewis-Sumner syndrome) and DADS (distal acquired demyelinating symmetric neuropathy) as variants. The clinical features, pathology, pathogenesis, diagnosis, treatment, rehabilitation, and prognosis of these neuropathies are discussed.

    Nursing home-acquired pneumonia (NHAP) was first described in 1978. Since then there has been much written regarding NHAP and its management despite the lack of well-designed studies in this patient population. The most characteristic features of patients with NHAP are the atypical presentation, which may lead to delay in diagnosis and therapy. The microbial etiology of pneumonia encompasses a wide spectrum that spans microbes recovered from patients with community-acquired pneumonia to organisms considered specific only to nosocomial settings. Decision to transfer a nursing home patient to an acute care facility depends on a host of factors, which include the level of staffing available at the nursing home, patients' advance directives, and complexity of treatment. The presence of risk factors for multidrug-resistant pathogens dictates approach to therapy. Prevention remains the cornerstone of reducing the incidence of disease. Despite the advance in medical services, mortality from NHAP remains high.

    Full Text Available The Southern African HIV Clinicians Society published its first set of oral pre-exposure prophylaxis (PrEP guidelines in June 2012 for men who have sex with men (MSM who are at risk of HIV infection. With the flurry of data that has been generated in PrEP clinical research since the first guideline, it became evident that there was a need to revise and expand the PrEP guidelines with new evidence of safety and efficacy of PrEP in several populations, including MSM, transgender persons, heterosexual men and women, HIV-serodiscordant couples and people who inject drugs. This need is particularly relevant following the World Health Organization (WHO Consolidated Treatment Guidelines released in September 2015. These guidelines advise that PrEP is a highly effective, safe, biomedical option for HIV prevention that can be incorporated with other combination prevention strategies in Southern Africa, given the high prevalence of HIV in the region. PrEP should be tailored to populations at highest risk of HIV acquisition, whilst further data from studies in the region accrue to guide optimal deployment to realise the greatest impact regionally. PrEP may be used intermittently during periods of perceived HIV acquisition risk, rather than continually and lifelong, as is the case with antiretroviral treatment. Recognition and accurate measurement of potential risk in individuals and populations also warrants discussion, but are not extensively covered in these guidelines.

    Acquired color vision deficiency occurs as the result of ocular, neurologic, or systemic disease. A wide array of conditions may affect color vision, ranging from diseases of the ocular media through to pathology of the visual cortex. Traditionally, acquired color vision deficiency is considered a separate entity from congenital color vision deficiency, although emerging clinical and molecular genetic data would suggest a degree of overlap. We review the pathophysiology of acquired color vision deficiency, the data on its prevalence, theories for the preponderance of acquired S-mechanism (or tritan) deficiency, and discuss tests of color vision. We also briefly review the types of color vision deficiencies encountered in ocular disease, with an emphasis placed on larger or more detailed clinical investigations.

    Acquired generalized lipodystrophy (AGL) is a rare disease thought to result from autoimmune destruction of adipose tissue. Peripheral T-cell lymphoma (PTCL) has been reported in two AGL patients. We report five additional cases of lymphoma in AGL, and analyze the role of underlying autoimmunity and recombinant human leptin (metreleptin) replacement in lymphoma development. Three patients developed lymphoma during metreleptin treatment (two PTCL and one ALK-positive anaplastic large cell lymphoma), and two developed lymphomas (mycosis fungoides and Burkitt lymphoma) without metreleptin. AGL is associated with high risk for lymphoma, especially PTCL. Autoimmunity likely contributes to this risk. Lymphoma developed with or without metreleptin, suggesting metreleptin does not directly cause lymphoma development; a theoretical role of metreleptin in lymphoma progression remains possible. For most patients with AGL and severe metabolic complications, the proven benefits of metreleptin on metabolic disease will likely outweigh theoretical risks of metreleptin in lymphoma development or progression.

    The emergence of human malaria due to the monkey parasite Plasmodium knowlesi threatens elimination efforts in southeast Asia. Changes in land use are thought to be driving the rise in reported P knowlesi cases, but the role of individual-level factors is unclear. To address this knowledge gap we assessed human and environmental factors associated with zoonotic knowlesi malaria risk. We did this population-based case-control study over a 2 year period in the state of Sabah in Malaysia. We enrolled cases with microscopy-positive, PCR-confirmed malaria who presented to two primary referral hospitals serving the adjacent districts of Kudat and Kota Marudu. We randomly selected three malaria-negative community controls per case, who were matched by village within 2 weeks of case detection. We obtained questionnaire data on demographics, behaviour, and residential malaria risk factors, and we also assessed glucose-6-phosphate dehydrogenase (G6PD) enzyme activity. We used conditional logistic regression models to evaluate exposure risk between P knowlesi cases and controls, and between P knowlesi and human-only Plasmodium spp malaria cases. From Dec 5, 2012, to Jan 30, 2015, we screened 414 patients and subsequently enrolled 229 cases with P knowlesi malaria mono-infection and 91 cases with other Plasmodium spp infection. We enrolled 953 matched controls, including 683 matched to P knowlesi cases and 270 matched to non-P knowlesi cases. Age 15 years or older (adjusted odds ratio [aOR] 4·16, 95% CI 2·09-8·29, ptravel (2·48, 1·45-4·23, p=0·0010), being aware of the presence of monkeys in the past 4 weeks (3·35, 1·91-5·88, p<0·0001), and having open eaves or gaps in walls (2·18, 1·33-3·59, p=0·0021) were independently associated with increased risk of symptomatic P knowlesi infection.

    Full Text Available

    Background: Risk assessment in relation to firearms and cognitive impairments is complex, and no guidelines exist regarding the appropriate management of people with dementia who may own or have access to a firearm. In Italy, approximately 4.8 million people either own a firearm or use one for recreational, sporting or professional reasons. Recent studies report that firearms were used in 35.7% of suicides committed by people over 65 years old and that 5% of all suicides were committed by over 65-year-olds using firearms. As for the figures related to homicides committed with firearms by people over 65, these represented 31.8% of all homicides committed with firearms.

    Results: The aim of the present study was to conduct a critical review of the procedures currently used in relation to the use of firearms by elderly people. We conducted a review of the international scientific literature published over the last 20 years on the phenomenon of firearms abuse by elderly people and its prevention, drawn from the Medline and PsychINFO online databases. We considered all studies published in journals and books from 1990 to 2010 using the following keywords: violence, firearms, suicide, homicide, dementia and cognitive impairments, and searching for quantitative studies, case reports and literature reviews.

    Conclusions: Family physicians and specialists (geriatricians, neuropsychiatrists, clinical psychologists can act as an indispensable observatory of the related risks in people who own firearms, but their role should be supported by suitable training on the procedures used to assess and report on any such risks.

    Current Centers for Disease Control and Prevention (CDC) guidelines for prescribing pre-exposure prophylaxis (PrEP) to prevent HIV transmission are broad. In order to better characterize groups who may benefit most from PrEP, we reviewed demographics, behaviors, and clinical outcomes for individuals presenting to a publicly-funded sexually transmitted diseases (STD) clinic in Providence, Rhode Island, from 2012 to 2014. Latent class analysis (LCA) was used to identify subgroups of men who have sex with men (MSM) at highest risk for contracting HIV. A total of 1723 individuals presented for testing (75% male; 31% MSM). MSM were more likely to test HIV positive than heterosexual men or women. Among 538 MSM, we identified four latent classes. Class 1 had the highest rates of incarceration (33%), forced sex (24%), but had no HIV infections. Class 2 had 10 anal sex partners in the previous 12 months (69%), anonymous partners (100%), drug/alcohol use during sex (76%), and prior STDs (40%). Class 4 had similar characteristics and HIV prevalence as Class 2. In this population, MSM who may benefit most from PrEP include those who have >10 sexual partners per year, anonymous partners, drug/alcohol use during sex and prior STDs. LCA is a useful tool for identifying clusters of characteristics that may place individuals at higher risk for HIV infection and who may benefit most from PrEP in clinical practice.

    We investigated whether the experience of homophobic events increases the odds of engaging in unprotected anal intercourse (UAI) among black men who have sex with men (MSM) and whether social integration level buffered the association. Participants (N = 1,154) reported homophobic events experienced in the past 12 months. Social integration measures included social support, closeness with family members and friends, attachment to the black gay community, openness about sexuality within religious communities, and MSM social network size. Logistic regression analyses indicated that experiencing homophobia was associated with (1) UAI among men not previously diagnosed with HIV and (2) sexual HIV transmission risk behavior among men who knew they were HIV-infected. None of the social integration measures buffered these associations. Homophobia may promote acquisition and transmission of HIV infection among black MSM. Interventions are needed to reduce homophobia experienced by black MSM.

    Although the risk of transfusion-transmitted hepatitis has been recently reduced, transfusion-dependent beta-thalassemia patients may still develop liver disease due to viral infection or iron overload. We assessed the frequency and causes of liver dysfunction in a cohort of anti-hepatitis C virus (HCV) negative thalassemics. Of 1,481 thalassemics enrolled in 31 centers, 219 (14.8%) tested anti-HCV- by second-generation assays; 181 completed a 3-year follow-up program consisting of alanine-aminotransferase (ALT) measurement at each transfusion and anti-HCV determination by third-generation enzyme-immunoassay (EIA-3) at the end of study. Serum ferritin levels were determined at baseline and at the end of follow-up. Ten patients were anti-HCV+ by EIA-3 at the end of follow-up. Of them, seven were already positive in 1992 to 1993 when the initial sera were retested by EIA-3, one tested indeterminate by confirmatory assay, and two had true seroconversion (incidence, 4. 27/1,000 person years; risk of infection, 1/7,100 blood units, 95% confidence interval [CI], 1 in 2,000-1 in 71,000 units). At baseline, 67 of 174 thalassemics had abnormal ALT. Of those with normal ALT, seven subsequently developed at least one episode of moderate ALT increase (incidence, 24.6/1,000 person-years). All of the 20 patients with ferritin values >/=3,000 ng/mL had clinically relevant ALT abnormalities, as compared with 53 of 151 with <3,000 ng/mL (P < .005). Hepatic dysfunction is still frequent in thalassemics. Although it is mainly attributable to siderosis and primary HCV infection, the role of undiscovered transmissible agents cannot be excluded.

    Full Text Available Smooth muscle hamartoma is an uncommon, usually congenital, cutaneous hyperplasia of the arrectores pilorum muscles. When it is acquired, it may be confused with Becker′s nevus. We report a case of this rare tumor in a 19-year-old man. The disease started several years ago as multiple small skin-colored papules that subsequently coalesced to form a large soft plaque on the back of the left shoulder. The diagnosis of acquired smooth muscle hamartoma was confirmed on histopathology. The patient was reassured about the benign nature of the lesion and was not advised any treatment.

    A prospective observational study of 226 intensive care unit (ICU) patients was conducted during a 25-month period. Rectal samples were taken at day 1, 4, and 7 and, afterwards, once weekly. Klebsiella pneumoniae was identified using standard techniques, whereas the presence of bla(KPC) gene was confirmed by PCR. During ICU stay, 72.6% of the patients were colonized with Klebsiella pneumoniae carbapenemases (KPC)-producing K. pneumoniae (KPC-Kp). Male gender, prior bed occupants, and patients in nearby beds colonized with KPC-Kp, tracheotomy, number of invasive catheters inserted, and number of antibiotics administered were the major risk factors for KPC-Kp colonization. ICU mortality (35.4%) was significantly related to Simplified Acute Physiology II score and respiratory insufficiency upon admission, cortisone administration, aminoglycoside administration, confirmed KPC-Kp infection, and severe sepsis or septic shock. The high prevalence of KPC-Kp enteric carriage in ICU patients and the significant mortality associated with KPC-Kp infection dictate the importance of early identification and isolation of such carriers.

    This study was undertaken to establish the sero-epidemology of Hepatitis C Virus (HCV) antibodies among blood donors in Port Harcourt, Nigeria. One Thousand Five Hundred consecutive blood donors presenting to the blood transfusion unit of the University of Port Harcourt Teaching Hospital between January and April, 2003 comprising of 1481 males and 19 females were screened for hepatitis C antibodies using the commercially available Clinotech anti-HCV test strips. All initially positive samples were subsequently tested using a second-generation Trinity Biotec enzyme linked immunosorbent assay. HCV antibodies were detected in 7 (0.5%) of donors. Although statistically not significant, the overall sero prevalence of HCV antibodies was higher in males 7 (0.5%) compared to zero prevalence among females. (chi-squared = 1.94, p = 1.000). Commercial remunerated donors had a higher prevalence of anti-HCV anti-bodies 5 (0.8%) compared to family replacement donors (0.2%) (chi-squared = 1.25, p = 0.26). The highest infection rate occurred in the 18 - 27 years age group 7 (0.7%). This study shows a 0.5% prevalence of HCV antibodies among blood donors and describes their demographic characteristics. This calls for urgent implementation of a universal donor screening for HCV antibodies and setting up of a national blood transfusion service run on the basis of voluntary, non-remunerated low risk donors.

    Listeriosis is characterized by bacteremia or meningitis. We searched for listeriosis case series and outbreak investigations published in English by 2013, and assessed the strength of evidence for foodborne acquisition among patients who ate hospital food. We identified 30 reports from 13 countries. Among the case series, the median proportion of cases considered to be hospital-acquired was 25% (range, 9%-67%). The median number of outbreak-related illnesses considered to be hospital-acquired was 4.0 (range, 2-16). All patients were immunosuppressed in 18 of 24 (75%) reports with available data. Eight outbreak reports with strong evidence for foodborne acquisition in a hospital implicated sandwiches (3 reports), butter, precut celery, Camembert cheese, sausage, and tuna salad (1 report each). Foodborne acquisition of listeriosis among hospitalized patients is well documented internationally. The number of listeriosis cases could be reduced substantially by establishing hospital policies for safe food preparation for immunocompromised patients and by not serving them higher-risk foods.

    Sterno-costo-clavicular hyperostosis (SCCH) is the most common manifestation of a syndrome, consisting of increased bone metabolism, mostly new bone formation and heterotopic ossification of fibrous tissue, which we have characterised as the acquired hyperostosis syndrome. In part I we discuss the terminology, radiological appearances, scintigraphy, clinical and laboratory findings, bacteriology, histology, nosology, complications, treatment and differential diagnosis of SCCH. Chronic recurrent multifocal osteomyelitis (CRMO) is regarded as a phaenotype of SCCH, depending on the age. CRMO occurs in children, adolescents and young adults, SCCH predominantly in middleaged and elderly adults.

    Full Text Available In postgraduate interpreter training, the main objective of the course is to help trainees develop various competences, from linguistic, textual and cultural competence, to professional and specific interpreting competence. For simultaneous interpreting (SI, the main focus is on mastering the SI technique and strategies as well as on developing and strengthening communicative skills, which is discussed and illustrated with examples in the present paper. First, a brief overview is given of all the necessary competences of a professional interpreter with greater emphasis on specific interpreting competence for SI. In the second part of the paper, various approaches are described in terms of acquiring specific skills and strategies, specifically through a range of exercises. Besides interpreting entire speeches, practical courses should also consist of targeted exercises, which help trainees develop suitable coping strategies and mechanisms (later on almost automatisms, while at the same time "force" them to reflect on their individual learning process and interpreting performance. This provides a solid base on which trained interpreters can progress and develop their skills also after joining the professional sphere.

    The response of a recently acquired Canberra{trademark} Alpha Analyst 'Blue' system (Chamber Number's 173-208) used by the Hazards Control, Radiation Safety Section, WBC/Spectroscopy Team has been studied with respect to an existing Canberra system. The existing Canberra system consists of thirty Alpha Analyst dual chambers Model XXXX comprising a total of sixty detectors (Chambers Number's 101-124 and 137-172). The existing chambers were previously compared to an older system consisting of thirty-six Model 7401 alpha spectrometry chambers (Chamber Number's 1-36) Chambers 101-124 and 137-172 are DOELAP accredited. The older system was previously DOELAP accredited for the routine Alpha Spectroscopy program used in LLNL's in vitro bioassay program. The newly acquired Alpha Analyst system operates on a network with software that controls and performs analysis of the current Alpha Analyst system (Chamber Number's 101-124 and 137-172). This exact same software is used for the current system and the newly acquired system and is DOELAP accredited. This document compares results from the existing Alpha System with the newer Alpha Analyst system.

    OBJECTIVE To investigate the characteristics and risk factors of hospital-acquired pneumonia (HAP) in elderly stroke patients. METHODS A retrospective study was performed on the characteristics and risk factors of HAP in 202 elderly stroke patients. RESULTS Of 202 elderly stroke patients, 54 patients got the HAP, the incidence rate was 26. 7%, the case-time rate was 49. 0%. The percentage of HAP was 30. 1% among total nosocomial infection patients during the same period. The main pathogens were Gram-negatives (61. 8%). The incidence rate of HAP was higher in elderly stroke patients with long-term hospitalization, antibiotics abuse and various invasive operations than the patients with short-term hospitalization, no use of antibiotics and invasive operations with statistical difference. CONCLUSION HAP has still a high incidence rate in elderly stroke patients and the main risk factors are long-term hospTtalization, antibiotics abuse and various invasive operations. Taking comprehensive precaution measures positively to reduce the risk factors is the key to decrease the incidence rate of HAP.%目的 探讨老年脑卒中患者医院获得性肺炎(HAP)的特点和危险因素.方法 对202例住院的老年脑卒中患者发生医院获得性肺炎特点及危险因素进行回顾性分析.结果 202例老年脑卒中患者中发生HAP 54例,感染率为26.7%,例次感染率为49.0%;病原菌以革兰阴性杆菌为主,分离得到革兰阴性菌42株,占61.8%;住院时间>30 d、抗菌药物滥用及有侵入性操作的老年脑卒中患者HAP发生率明显高于住院时间≤30 d、无抗菌药物滥用及无侵入性操作患者,两者差异有统计学意义(P<0.05).结论 老年脑卒中患者是HAP高发人群,住院时间长、侵人性操作及滥用抗菌药物等是HAP的危险因素,故积极采取综合防范措施,减少危险因素,是降低HAP发生率的关键.

    propounded as to how maternally transmitted graft-versus-host reactivity might lead to the development of these tumors. In mice it has been established that graft-versus-host reactivity may result in a high incidence of lymphomas (18). Recent analysis indicates that this graft-versus-host reactivity unmasks and activates normally latent and undemonstrable oncogenic viruses (19). The work we describe in this article may have some relevance to the possible clinical significance of transplacental cellular mobility in man. We suggest that the relatively high incidence of lymphomas in children might also be, in part at least, due to unmasking of oncogenic viruses by subclinical graft-versus-host reactivity mediated by immunocompetent cells of maternal origin. The statistical evidence that male infants are at greater risk than females (20) is concordant with our observation that maternally induced runts include a significantly higher proportion of males than females (10).

    Acquired immunodeficiency syndrome (AIDS) is reviewed for dental practitioners, with an emphasis on oral findings; the clinical course, diagnosis, reporting, treatment, prognosis, transmission, and epidemiology are also covered. HIV infection has an incubation period that may be associated with glandular fever, a prodrome called AIDS-Related Complex (ARC) characterized by lymphadenopathy, low fever, weight loss, night sweats, diarrhea, oral candidosis, nonproductive cough and recurrent infections. AIDS is characterized by opportunistic infections. Over 50% present with pneumocystis carinii pneumonia, 21% with Kaposi's sarcoma, and 6% have both. The AIDS virus causes direct neurological symptoms in some cases. Oral candidosis (thrush) in a young male without a local cause such as xerostomia or immune suppression is strongly suggestive of AIDS. Other oral manifestations are severe herpes simplex, varicella-zoster, Epstein-Barr virus, cytomegalovirus, venereal warts, aphthous ulceration, mycobacterial oral ulcers, oral histoplasmosis, sinusitis and osteomyelitis of the jaw. Hairy leukoplakia, usually seen on the lateral border of the tongue, is probably caused by Epstein-Barr virus. Kaposi's sarcoma, an endothelial cell tumor, is characteristic of AIDS, and in 50% of patients is oral or perioral. Cervical lymph node enlargement will be seen in those with ARC as well as AIDS. No guidelines have been issued by the Department of Health and Social Security for dental surgeons in the UK for reporting AIDS cases. Although HIV virions have been isolated from saliva, there are no known incidents of transmission via saliva. HIV is less likely to be transmitted by needle stick injuries than, for example hepatitis B (25% risk), especially if the blood is from a carrier rather than a full blown AIDS case.

    Portosystemic shunts are enlarged vessels that form collateral pathological pathways between the splanchnic circulation and the systemic circulation. Although their causes are multifactorial, portosystemic shunts all have one mechanism in common-increased portal venous pressure, which diverts the blood flow from the gastrointestinal tract to the systemic circulation. Congenital and acquired collateral pathways have both been described in the literature. The aim of this pictorial essay was to discuss the distinct anatomic and imaging features of portosystemic shunts, as well as to provide a robust method of differentiating between acquired portosystemic shunts and similar pathologies, through the use of illustrations and schematic drawings. Imaging of portosystemic shunts provides subclinical markers of increased portal venous pressure. Therefore, radiologists play a crucial role in the identification of portosystemic shunts. Early detection of portosystemic shunts can allow ample time to perform endovascular shunt operations, which can relieve portal hypertension and prevent acute or chronic complications in at-risk patient populations.

    The incidence of community-acquired pneumonia complications has increased during the last decade. According to the records from several countries, empyema and necrotizing pneumonia became more frequent during the last few years. The optimal therapeutic approach for such conditions is still controversial. Both pharmacological management (antimicrobials and fibrinolysis), and surgical management (pleural drainage and video-assisted thoracoscopic surgery), are the subject of continuous assessment. In this paper, the Spanish Society of Paediatric Infectious Diseases and the Spanish Society of Paediatric Chest Diseases have reviewed the available evidence. Consensus treatment guidelines are proposed for complications of community-acquired pneumonia in children, focusing on parapneumonic pleural effusion. Recommendations are also provided for the increasing population of patients with underlying diseases and immunosuppression. Copyright © 2014 Asociación Española de Pediatría.

  16. Impact of newly recommended HbA1c-based diabetes diagnostic criteria on the prevalence of diabetes and high risk individual in clinical and community population in China

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    @@ To the editor: Recently, the International Expert Committee recommended using HbAlc as a diagnosing tool for diabetes and suggested HbAlc value of 6.5% as cut-off for the diagnosis.~1 In this recommendation, pre-diabetes was replaced by "sub-diabetes or high risk status" which was defined by HbAlc between 6.0% and 6.5%. The recommendation has triggered wide discussion on its potential influence on diabetes care, for example, the impact of the new diabetes diagnosis criteria on the prevalence of diabetes. We have noticed that the level of HbAlc correlated with oral glucose tolerance test (OGTT) based diabetes diagnosis criteria~2 is lower than 6.5%.~(3,4) We hypothesized that the new diagnosis criteria will reduce the prevalence of both diabetes and high risk population in Chinese population. To test this hypothesis, we calculated the prevalence of diabetes and high risk individuals in both community and hospital based diabetes screening population by using both OGTT based2 and HbAlc based diagnosis criteria.

    Hypercholesterolaemia, characterised by raised blood cholesterol levels, is not a disease itself but a metabolic derangement that often contributes to many diseases, notably cardiovascular disease. In most cases, elevated cholesterol levels are associated with high-fat diet, especially saturated fat, coupled with an inactive lifestyle. Less commonly, raised cholesterol may be related to an inherited disorder, familial hypercholesterolaemia. This systematic review is only concerned with acquired hypercholesterolaemia. To assess the effects of low-fat diets for acquired hypercholesterolaemia and to investigate the incidence of adverse effects from low-fat dietary interventions. We planned to compare the relative effectiveness of low-fat diets with calorie-restricted diets for acquired hypercholesterolaemia. We also wanted to look into the relative effectiveness of low-fat diets and pharmacological interventions for acquired hypercholesterolaemia. Studies were obtained from computerised searches of The Cochrane Library, MEDLINE, EMBASE and databases of ongoing trials. Date of last search was February 2010. Otherwise healthy adults (equal to or greater than 18 years) with acquired (not familial) hypercholesterolaemia. We defined hypercholesterolaemia as either total cholesterol greater than 5.2 mmol/L, LDL-cholesterol greater than 3.0 mmol/L, HDL-cholesterol less than 1.0 mmol/L or a combination thereof, although investigators' definitions were also accepted. We wanted to include any low-fat dietary intervention, like low-fat and low-saturated fat diets, intended to lower serum total and LDL-cholesterol or to raise HDL-cholesterol. A low-fat diet was considered as a fat calorie intake less than 20% of the total calories. The minimum duration of the intervention had to be six months. We excluded studies in unhealthy people. Two authors were planned to independently assess risk of bias and extract data. No study met our inclusion criteria. Well designed, adequately

    Recent studies have left absolutely no doubt that tobacco increases susceptibility to bacterial lung infection, even in passive smokers. This relationship also shows a dose-response effect, since the risk reduces spectacularly 10 years after giving up smoking, returning to the level of non-smokers. Streptococcus pneumoniae is the causative microorganism responsible for community-acquired pneumonia (CAP) most frequently associated with smoking, particularly in invasive pneumococcal disease and septic shock. It is not clear how it acts on the progress of pneumonia, but there is evidence to suggest that the prognosis for pneumococcal pneumonia is worse. In CAP caused by Legionella pneumophila, it has also been observed that smoking is the most important risk factor, with the risk rising 121% for each pack of cigarettes smoked a day. Tobacco use may also favor diseases that are also known risk factors for CAP, such as periodontal disease and upper respiratory viral infections. By way of prevention, while giving up smoking should always be proposed, the use of the pneumococcal vaccine is also recommended, regardless of the presence of other comorbidities.

    The acquired immunodeficiency syndrome (AIDS) is a major health problem for gay men in the United States. About three fourths of all reported cases have occurred in this population, and the number is projected to double in the next year. In Manhattan and San Francisco, AIDS is now the leading cause of premature mortality in men aged 25 to 44 years who have never married. In a sample of a cohort of gay men enrolled in a San Francisco clinic, 2.7% of the men had the syndrome and 26% had related conditions in 1984. Antibody to human T-lymphotropic virus, type III/lymphadenopathy-associated virus was found in sera from 67% of the men, including 58% of asymptomatic men. Behavioral factors associated with an increased risk of AIDS include large numbers of sexual partners, receptive anal intercourse, and "fisting." The adoption of safer lifestyles is currently the basis of attempts to control the syndrome in gay men.

    This study reviewed the clinical history and management of acquired growth arrest in the upper extremity in pediatric patients. The records of all patients presenting from 1996 to 2012 with radiographically proven acquired growth arrest were reviewed. Records were examined to determine the etiology and site of growth arrest, management, and complications. Patients with tumors or hereditary etiology were excluded. A total of 44 patients (24 boys and 20 girls) with 51 physeal arrests who presented at a mean age of 10.6 years (range, 0.8-18.2 years) were included in the study. The distal radius was the most common site (n=24), followed by the distal humerus (n=8), metacarpal (n=6), distal ulna (n=5), proximal humerus (n=4), radial head (n=3), and olecranon (n=1). Growth arrest was secondary to trauma (n=22), infection (n=11), idiopathy (n=6), inflammation (n=2), compartment syndrome (n=2), and avascular necrosis (n=1). Twenty-six patients (59%) underwent surgical intervention to address deformity caused by the physeal arrest. Operative procedures included ipsilateral unaffected bone epiphysiodesis (n=21), shortening osteotomy (n=10), lengthening osteotomy (n=8), excision of physeal bar or bone fragment (n=2), angular correction osteotomy (n=1), and creation of single bone forearm (n=1). Four complications occurred; 3 of these required additional procedures. Acquired upper extremity growth arrest usually is caused by trauma or infection, and the most frequent site is the distal radius. Growth disturbances due to premature arrest can be treated effectively with epiphysiodesis or osteotomy. In this series, the specific site of anatomic growth arrest was the primary factor in determining treatment. [Orthopedics. 2017; 40(1):e95-e103.]. Copyright 2016, SLACK Incorporated.

    Speaking up, i.e. expressing ones concerns, is a critical piece of effective communication. Yet, we see many situations in which crew members have concerns and still remain silent. Why would that be the case? And how can we assess the risks of speaking up vs. the risks of keeping silent? And once we do make up our minds to speak up, how should we go about it? Our workshop aims to answer these questions, and to provide us all with practical tools for effective risk assessment and effective speaking-up strategies..

    Nevus of Ota is a unilateral, asymptomatic cutaneous and mucosal hyperpigmentation of the face that is congenital or may appear during childhood. We present a case of symptomatic acquired nevus of Ota in an adult, associated with intense pruritus, not described in the literature so far. A 32-year-old woman presented with brownish mottled macules which appeared on her face progressively over 8 days, following the distribution of the first and second divisions of the left trigeminal nerve and partially covering the iris and sclera of the left eye. She reported an intense pruritus in this area. We performed a biopsy on the left forehead, which confirmed the diagnosis of nevus of Ota. Specific stains and immunohistochemistry revealed increased numbers of mast cells. Ophthalmological tests showed acute acquired melanocytosis of the left iris and sclera. The origin of the nevus is still unclear. Several hypotheses suggest a reactivation of melanocytes during their migration from the neural crest. The pruritus reported in our patient may be explained by the increased quantity of mast cells observed in the lesion and/or neuronal stimulation of the ophthalmic and maxillary divisions of the fifth cranial nerve.

     Prospective, observational, ecological, time series, cross-sectional study examining the association between hand hygiene compliance (HHC) rates and the incidence of hospital-acquired infections.  Acute care hospitals (N = 166) located in the province of Ontario, Canada.  All data were extracted from the Ontario patient safety indicator database ( http://www.hqontario.ca/public-reporting/patient-safety). Complete data were available for 166 acute care hospitals from October 1, 2008, to December 31, 2011. The rates of Clostridium difficile infection (CDI) are reported monthly, methicillin-resistant Staphylococcus aureus (MRSA) bacteremia quarterly, and HHC rates yearly. Trends and associations for each indicator were evaluated by ordinary least squares regression (HHC), zero-inflated Poisson regression (MRSA bacteremia), or Poisson regression (CDI). Dependent variables included in the regression analyses were extracted from the same database and included year, healthcare region, and type of hospital (teaching or small or large community). Compared to those in 2008, reported HHC rates improved every year both before and after environment/patient contact (range, 10.6%-25.3%). Compared to those in 2008, there was no corresponding change in the rates of MRSA bacteremia; however, the rates of CDI decreased in 2009 but were not statistically significantly decreased from baseline in either 2010 or 2011. No consistent association was demonstrated between changes in the rates of HHC and these two healthcare-associated infections (HAIs).  Despite significant improvements in reported rates of HHC among healthcare personnel in Ontario's hospitals, we could not demonstrate a positive ecological impact on rates of these two HAIs.

  7. Bejel: acquirable only in childhood?

    2006-10-01

    Bejel clearly has a long history in the Middle East and the Sudan, but was it transmitted to Europe? As the major manifestation of bejel is presence of periosteal reaction in 20-40% of afflicted populations, absence of significant population frequency of periosteal reaction in Europe would exclude that diagnosis. Examination of skeletal populations from continental Europe revealed no significant periosteal reaction at the time of and immediately subsequent to the Crusades. Thus, there is no evidence for bejel in Europe, in spite of clear contact (the mechanism of bejel transmission in children) between warring groups, at least during the Crusades. This supports the hypothesis that bejel is a childhood-acquired disease and apparently cannot be contracted in adulthood.

    The aim of this study was to assess mortality and sequellae within cases from Nationwide survey of community acquired meningitis and identify risk factors for inferior outcome. Risk factors such as underlying disease (diabetes mellitus, cancer, trauma, neonatal age, splenectomy, alcoholism, sepsis, other infections), etiology, clinical symptoms and outcome (death, improvement and cured after modifications of ATB therapy, cured without change of therapy, cured with neurologic sequellae) were recorded and analysed with univariate analysis (chi2 or t test for trends, CDC Atlanta 2004). Analysing risk factors for inferior outcome (death or cured with neurologic sequellae), we compared patients who died or survived with neurologic sequellae to all patients with community acquired bacterial meningitis. Univariate analysis showed that trauma (palcohol abuse (pdiabetes, S. aureus (pdiabetes mellitus (palcoholism (palcohol abuse (p<0.05), craniocerbral trauma (p<0.05) and less common in meningitis with pneumococcal etiology (p<0.05).

    INTRODUCTION: The incidence of new HIV diagnoses in Denmark has remained stable since 1991, but it has increased among the subgroup of homosexual men in recent years. This may reflect an actual increase in newly infected, e.g. as a result of increased risk behaviour, or it may reflect increased HIV....... MATERIALS AND METHODS: Observational study based on the Danish HIV Cohort Study, which includes all adults seen at Danish HIV clinics since 1995. RESULTS: From 2000 to 2004 the number of newly-infected homosexual men increased (from 69 to 123), particularly in persons under 30 years (from 5 to 42...... from 0 in 2000 to 23 in 2004. The prevalence of patients with high viral load (and thus potentially at risk of transmitting HIV) decreased in all risk groups.

    Full Text Available Abstract Background The aim of our study was to investigate the predictive value of the biomarkers interleukin 6 (IL-6, interleukin 10 (IL-10 and lipopolysaccharide-binding protein (LBP compared with clinical CRB and CRB-65 severity scores in patients with community-acquired pneumonia (CAP. Methods Samples and data were obtained from patients enrolled into the German CAPNETZ study group. Samples (blood, sputum and urine were collected within 24 h of first presentation and inclusion in the CAPNETZ study, and CRB and CRB-65 scores were determined for all patients at the time of enrollment. The combined end point representative of a severe course of CAP was defined as mechanical ventilation, intensive care unit treatment and/or death within 30 days. Overall, a total of 1,000 patients were enrolled in the study. A severe course of CAP was observed in 105 (10.5% patients. Results The highest IL-6, IL-10 and LBP concentrations were found in patients with CRB-65 scores of 3-4 or CRB scores of 2-3. IL-6 and LBP levels on enrollment in the study were significantly higher for patients with a severe course of CAP than for those who did not have severe CAP. In receiver operating characteristic analyses, the area under the curve values for of IL-6 (0.689, IL-10 (0.665 and LPB (0.624 in a severe course of CAP were lower than that of CRB-65 (0.764 and similar to that of CRB (0.69. The accuracy of both CRB and CRB-65 was increased significantly by including IL-6 measurements. In addition, higher cytokine concentrations were found in patients with typical bacterial infections compared with patients with atypical or viral infections and those with infection of unknown etiology. LBP showed the highest discriminatory power with respect to the etiology of infection. Conclusions IL-6, IL-10 and LBP concentrations were increased in patients with a CRB-65 score of 3-4 and a severe course of CAP. The concentrations of IL-6 and IL-10 reflected the severity of disease in

    2016-11-01

    Background: Synthetic drug use and abuse are on the rise. Governmental institutions report a shift in consumption from natural drugs to synthetic drugs, and show an increase in confiscation, particularly of methamphetamine and newly identified psychoactive substances. In addition, the media report an alarming increase in the rate of consumption and casualties resulting from the use of drugs such as "crystal meth" and warn against a flood of this and other designer drugs from eastern European countries. Objectives: The present article gives an overview of current popular and widely used synthetic drugs, both classical substances (amphetamine, methamphetamine, MDMA) and new psychoactive substances ("designer drugs", "legal highs"). It addresses their pharmacology, effects, side effects, and risks. It furthermore explores newly emerging problems for the health system and clinical practice regarding the treatment of intoxication as well as withdrawal. Methods: The current scientific literature concerning synthetic drugs is summarized and official statistics and reports provided by the government are reviewed. Results: Different derivatives of amphetamine vary in their risk of harm and addictive potential. Methamphetamine, one of the most dangerous derivatives, is increasingly being consumed in certain regions of Germany. New psychoactive substances represent a heterogeneous group of substances. Since the substances are often unknown to the user, they are unpredictable in their effects and side effects.

  17. Life style factors and acquired susceptibility to environmental disease.

    Science.gov (United States)

    Au, W W

    2001-10-01

    Multifactorial risk factors are responsible for many diseases. They can be broadly categorized as environmental, genetic and life style factors. Much attention has been focused on the first two categories, e.g. the identification of environmental toxicants/carcinogens and the elucidation of genetic susceptibility to disease. Life style risk factors such as aging, poor nutrition, infection and exposure to toxicants can also increase susceptibility to illnesses. These life style factors can therefore be considered to cause acquired susceptibility for increased risk for environmental disease. Among Egyptians, infection with the parasite, Schistosoma, is the primary risk factor for bladder cancer and the risk is enhanced by exposure to mutagenic chemicals. We have shown that inheritance of susceptible metabolizing genes that can increase body burden of mutagenic chemicals enhances the risk. We have also hypothesized that chronic exposure to mutagenic chemicals causes cellular abnormalities that can reduce the capacity of cells to repair DNA damage and thus increase the risk for environmental disease. We have used a challenge assay to show that cells from cigarette smokers and from populations exposed to uranium, butadiene and pesticides have abnormal DNA repair responses compared to matched controls. On the other hand, the response is normal in workers exposed to very low concentrations of butadiene and benzene, and in mothers who had children with birth defects. This suggests that exposure to high enough concentrations of certain mutagens can cause acquired susceptibility in human populations. The acquired susceptibility is expected to interact with environmental factors and with genetic susceptibility to increase risk for environmental disease.

  18. Establishment probability in newly founded populations

    2012-06-01

    Full Text Available Abstract Background Establishment success in newly founded populations relies on reaching the established phase, which is defined by characteristic fluctuations of the population’s state variables. Stochastic population models can be used to quantify the establishment probability of newly founded populations; however, so far no simple but robust method for doing so existed. To determine a critical initial number of individuals that need to be released to reach the established phase, we used a novel application of the “Wissel plot”, where –ln(1 – P0(t is plotted against time t. This plot is based on the equation P0t=1–c1e–ω1t, which relates the probability of extinction by time t, P0(t, to two constants: c1 describes the probability of a newly founded population to reach the established phase, whereas ω1 describes the population’s probability of extinction per short time interval once established. Results For illustration, we applied the method to a previously developed stochastic population model of the endangered African wild dog (Lycaon pictus. A newly founded population reaches the established phase if the intercept of the (extrapolated linear parts of the “Wissel plot” with the y-axis, which is –ln(c1, is negative. For wild dogs in our model, this is the case if a critical initial number of four packs, consisting of eight individuals each, are released. Conclusions The method we present to quantify the establishment probability of newly founded populations is generic and inferences thus are transferable to other systems across the field of conservation biology. In contrast to other methods, our approach disaggregates the components of a population’s viability by distinguishing establishment from persistence.

  19. Inherited or acquired metabolic disorders.

    2016-01-01

    This chapter starts with a description of imaging of inherited metabolic disorders, followed by a discussion on imaging of acquired toxic-metabolic disorders of the adult brain. Neuroimaging is crucial for the diagnosis and management of a number of inherited metabolic disorders. Among these, inherited white-matter disorders commonly affect both the nervous system and endocrine organs. Magnetic resonance imaging (MRI) has enabled new classifications of these disorders that have greatly enhanced both our diagnostic ability and our understanding of these complex disorders. Beyond the classic leukodystrophies, we are increasingly recognizing new hereditary leukoencephalopathies such as the hypomyelinating disorders. Conventional imaging can be unrevealing in some metabolic disorders, but proton magnetic resonance spectroscopy (MRS) may be able to directly visualize the metabolic abnormality in certain disorders. Hence, neuroimaging can enhance our understanding of pathogenesis, even in the absence of a pathologic specimen. This review aims to present pathognomonic brain MRI lesion patterns, the diagnostic capacity of proton MRS, and information from clinical and laboratory testing that can aid diagnosis. We demonstrate that applying an advanced neuroimaging approach enhances current diagnostics and management. Additional information on inherited and metabolic disorders of the brain can be found in Chapter 63 in the second volume of this series.

    Squamous cell carcinoma (SCC) is among the most frequent types of cancer constituting a significant public health burden. Prevention strategies focus on limiting UV-exposure during leisure time. However, the relative impact of occupational and non-occupational UV-exposure for SCC occurrence is unclear. To investigate the association between occupational and non-occupational UV-exposure with SCC in a multicenter population-based case-control study hypothesizing that high occupational UV-exposure increases the risk for SCC. Consecutive patients with incident SCC (n=632) were recruited from a German national dermatology network. Population-based controls (n=996) without history of skin cancer were recruited from corresponding residents' registration offices and propensity score matched to cases. Lifetime UV-exposure, sociodemographic and clinical characteristics were assessed by trained physicians. Occupational and non-occupational UV-exposure dosages were estimated by blinded investigators using established reference values. Odds ratios (OR) and corresponding 95%-confidence intervals (95%-CI) were assessed using conditional logistic regression adjusting for relevant confounders. Total solar UV-exposure was significantly associated with an increased SCC. The OR (95%-CI) for high (>90(th) percentile) vs. low (exposure was 1.95 (1.19-3.18) and 2.44 (1.47-4.06) for SCC. Adjusting for occupational UV-exposure non-occupational UV-exposure was not significantly related to SCC incidence. Dose-response relationships were observed for occupational but not for non-occupational solar UV-exposure. Solar occupational UV-exposure is a major determinant of incident SCC. Our findings indicate that prevention strategies should be further expanded to the occupational setting. This article is protected by copyright. All rights reserved.

    2003-01-01

    Full Text Available Community-acquired pneumonia (CAP is common among children and may have viral, bacterial or, occasionally, other causes. The etiology is complex, with age-related trends, and differs from that in adult CAP, necessitating different management guidelines. There is an absence of current guidelines for the management of pediatric CAP (PCAP that take into account changing etiologies, antimicrobial-resistance issues and the use of newly licensed antimicrobials. The present review does not provide specific guidelines, but it reviews the literature and presents currrent approaches to the treatment of PCAP. To compile the review, an expert panel was convened to provide a consensus. The review discusses the etiology, diagnosis and antimicrobial treatment of PCAP as well as indications for referral to a hospital emergency department. The goal of the review is to provide those involved with treatment of PCAP in the community setting with information that can be used to make effective treatment choices.

    2007-08-01

    Because some native ungulates have lived without top predators for generations, it has been uncertain whether runaway predation would occur when predators are newly restored to these systems. We show that landscape features and vegetation, which influence predator detection and capture of prey, shape large-scale patterns of predation in a newly restored predator-prey system. We analysed the spatial distribution of wolf (Canis lupus) predation on elk (Cervus elaphus) on the Northern Range of Yellowstone National Park over 10 consecutive winters. The influence of wolf distribution on kill sites diminished over the course of this study, a result that was likely caused by territorial constraints on wolf distribution. In contrast, landscape factors strongly influenced kill sites, creating distinct hunting grounds and prey refugia. Elk in this newly restored predator-prey system should be able to mediate their risk of predation by movement and habitat selection across a heterogeneous risk landscape.

    This paper reports the findings from a study of newly qualified nurses and which subjects the nurses regarded as the most important in order to be able to live up to the requirements of clinical practice, and how they experience their potential for developing practical and moral skills, after the decrease in practical training. A qualitative approach guided the research process and the analysis of the data. The data was collected by participant observation and qualitative interviews with four nurses as informants. The conclusions made in this study are based on the statements and the observations of the newly qualified nurses. Our findings are discussed in relation to the Aristotelian concept and other relevant literature. The main message is that the newly qualified nurses did not feel equipped when they finished their training. This could be interpreted as a direct consequence of the decrease in practical training. Our study also underlines that the way nursing theory is perceived and taught is problematic. The interviews revealed that the nurses think that nursing theories should be applied directly in practice. This misunderstanding is probably also applicable to the teachers of the theories.

    Aim of this prospective study was to investigate prognostic significance of increased bone marrow microcirculation as detected by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) for survival and local complications in patients with multiple myeloma (MM). We performed DCE-MRI of the lumbar spine in 131 patients with newly diagnosed MM and analysed data according to the Brix model to acquire amplitude A and exchange rate constant k{sub ep}. In 61 patients a second MRI performed after therapy was evaluated to assess changes in vertebral height and identify vertebral fractures. Correlation analysis revealed significant positive association between beta2-microglobulin as well as immunoparesis with DCE-MRI parameters A and k{sub ep}. Additionally, A was negatively correlated with haemoglobin levels and k{sub ep} was positively correlated with LDH levels. Higher baseline k{sub ep} values were associated with decreased vertebral height in a second MRI (P = 0.007) and A values were associated with new vertebral fractures in the lower lumbar spine (P = 0.03 for L4). Pre-existing lytic bone lesions or remission after therapy had no impact on the occurrence of vertebral fractures. Multivariate analysis revealed that amplitude A is an independent adverse risk factor for overall survival. DCE-MRI is a non-invasive tool with significance for systemic prognosis and vertebral complications. (orig.)

    Full Text Available Understanding how the mappings between orthography and phonology in alphabetic languages are learned, represented and processed has been enhanced by the cognitive neuropsychological investigation of patients with acquired reading and writing disorders. During the past decade, this methodology has been extended to understanding reading and writing in Chinese leading to new insights about language processing, dyslexia and dysgraphia. The aim of this paper is to review reports of patients who have acquired dyslexia and acquired dysgraphia in Chinese and describe the functional architecture of the reading and writing system. Our conclusion is that the unique features of Chinese script will determine the symptoms of acquired dyslexia and dysgraphia in Chinese.

    This study sought to understand whether UK Foundation doctors perceived the phenomena of ethical erosion and empathy decline during their initial period of clinical practice, and if so, why this occurred. This qualitative study used semi-structured interviews with nine doctors in their first year of clinical practice at Royal Bolton Hospital, UK. Participants were invited to discuss the definition of empathy, how individuals acquire and maintain empathic ability, perceptions of ethical erosion in the self and others, and how clinical experiences have influenced their empathic ability. The interviews were transcribed, and analysed to identify emergent themes. Each participant reported a conscious acknowledgement of empathy decline in their own and their colleagues' early clinical experiences as doctors. Stressful working environments, the prioritisation of patients' physical rather than psychological well-being, and the attitudes of senior colleagues were all suggested as possible causes. Some doctors believed that specialties with reduced patient contact had a culture which precluded empathy, and influenced their own practice. In addition, some described how their value judgements of patients had affected their ability to empathise. However, all doctors perceived that empathy skills were desirable in senior clinicians, and some believed that educational interventions may be useful in arresting ethical erosion. Newly qualified doctors are aware of ethical erosion in themselves and their colleagues as they begin clinical practice. This has serious implications for patient care. Improving working conditions may reverse this trend. Empathy skills training within undergraduate and postgraduate curricula may be a useful intervention.

    In this study the performance of two newly developed personal bioaerosol samplers was evaluated. The two test samplers are cyclone-based personal samplers that incorporate a recirculating liquid film. The performance evaluations focused on the physical efficiencies that a personal bioaerosol sampler could provide, including aspiration, collection, and capture efficiencies. The evaluation tests were carried out in a wind tunnel, and the test personal samplers were mounted on the chest of a full-size manikin placed in the test chamber of the wind tunnel. Monodisperse fluorescent aerosols ranging from 0.5 to 20 microm were used to challenge the samplers. Two wind speeds of 0.5 and 2.0 m/sec were employed as the test wind speeds in this study. The test results indicated that the aspiration efficiency of the two test samplers closely agreed with the ACGIH inhalable convention within the size range of the test aerosols. The aspiration efficiency was found to be independent of the sampling orientation. The collection efficiency acquired from these two samplers showed that the 50% cutoff diameters were both around 0.6 microm. However the wall loss of these two test samplers increased as the aerosol size increased, and the wall loss of PAS-4 was considerably higher than that of PAS-5, especially in the aerosol size larger than 5 microm, which resulted in PAS-4 having a relatively lower capture efficiency than PAS-5. Overall, the PAS-5 is considered a better personal bioaerosol sampler than the PAS-4.

  11. Community-acquired pneumonia; Ambulant erworbene Pneumonien

    The diagnosis of community-acquired pneumonia (CAP) is often not possible based only on the clinical symptoms and biochemical parameters. For every patient with the suspicion of CAP, a chest radiograph in two planes should be carried out. Additionally, a risk stratification for the decision between outpatient therapy or hospitalization is recommended. Based on the evaluation of the different radiological patterns as well as their extent and distribution, a rough allocation to so-called pathogen groups as well as a differentiation between viral and bacterial infections are possible; however, because different pathogens cause different patterns an accurate correlation is not feasible by relying purely on imaging. The radiological findings serve as proof or exclusion of pneumonia and can also be used to evaluate the extent of the disease (e.g. monolobular, multilobular, unilateral or bilateral). In cases of prolonged disease, suspicion of complications (e.g. pleural effusion or empyema, necrotizing pneumonia or abscess) or comorbid conditions (e.g. underlying pulmonary or mediastinal diseases) computed tomography is an important diagnostic tool in addition to chest radiography. Ultrasound is often used to diagnose pleural processes (e.g. parapneumonic effusion or pleural empyema). (orig.) [German] Anhand der klinischen Symptome und laborchemischen Befundkonstellation alleine ist es oft nicht moeglich, die Diagnose einer ambulant erworbenen Pneumonie (''community-acquired pneumonia'', CAP) zu stellen. Bei jedem Patienten mit Verdacht auf CAP sollte eine Roentgenthoraxaufnahme in 2 Ebenen angefertigt werden. Weiter muss eine Risikostratifizierung im Sinne der Entscheidung ambulante Therapie vs. Hospitalisierung erfolgen. Anhand der Analyse radiologischer Muster sowie deren Verteilung und Ausdehnung koennen eine grobe Zuordnung zu sogenannten Erregergruppen sowie eine Differenzierung zwischen viralen und bakteriellen Infektionen gelingen.

  14. Mammalian-specific genomic functions: Newly acquired traits generated by genomic imprinting and LTR retrotransposon-derived genes in mammals

    2015-01-01

    Mammals, including human beings, have evolved a unique viviparous reproductive system and a highly developed central nervous system. How did these unique characteristics emerge in mammalian evolution, and what kinds of changes did occur in the mammalian genomes as evolution proceeded? A key conceptual term in approaching these issues is “mammalian-specific genomic functions”, a concept covering both mammalian-specific epigenetics and genetics. Genomic imprinting and LTR retrotransposon-derived genes are reviewed as the representative, mammalian-specific genomic functions that are essential not only for the current mammalian developmental system, but also mammalian evolution itself. First, the essential roles of genomic imprinting in mammalian development, especially related to viviparous reproduction via placental function, as well as the emergence of genomic imprinting in mammalian evolution, are discussed. Second, we introduce the novel concept of “mammalian-specific traits generated by mammalian-specific genes from LTR retrotransposons”, based on the finding that LTR retrotransposons served as a critical driving force in the mammalian evolution via generating mammalian-specific genes.

    Next-generation sequencing(NGS) technologies have made high-throughput sequencing available to medium- and small-size laboratories, culminating in a tidal wave of genomic information. The quantity of sequenced bacterial genomes has not only brought excitement to the field of genomics but also heightened expectations that NGS would boost antibacterial discovery and vaccine development. Although many possible drug and vaccine targets have been discovered, the success rate of genome-based analysis has remained below expectations. Furthermore, NGS has had consequences for genome quality, resulting in an exponential increase in draft(partial data) genome deposits in public databases. If no further interests are expressed for a particular bacterial genome, it is more likely that the sequencing of its genome will be limited to a draft stage, and the painstaking tasks of completing the sequencing of its genome and annotation will not be undertaken. It is important to know what is lost when we settle for a draft genome and to determine the "scientific value" of a newly sequenced genome. This review addresses the expected impact of newly sequenced genomes on antibacterial discovery and vaccinology. Also, it discusses the factors that could be leading to the increase in the number of draft deposits and the consequent loss of relevant biological information.

    This prospective study was designed to (1) test the hypothesis that the majority of families of newly dead infants in a tertiary neonatal intensive care unit would consent to their infants' being intubated for teaching purposes, (2) determine factors related to family consent, and (3) determine the effects of participation on resident physicians and respiratory therapists. Family consent for intubation was requested following 44 (80%) of the 55 deaths that occurred during the 10-month study period. Of these requests, 32 (73%) were granted. Proportionately more white than black families consented and consent was positively related to autopsy permission. Fifty-three (75%) of 71 trainees completed a mailed questionnaire after their first intubation experience. Although each respondent found the experience helpful, many reported mixed feelings categorized as doubt about participating, apprehension and discomfort, respect for the body, appreciation for the opportunity, a sense of achievement, and feelings of comfort knowing that consent had been obtained. These findings confirm our initial hypothesis and suggest that (1) newly dead infants can be a valuable resource for teaching intubation skills, and (2) others considering a similar approach need to be aware of and sensitive to trainees' feelings.

    Objective To identify antimicrobial susceptibilities of community-acquired Staphylococcus aureus infections and the risk factors of severe infections.Methods Clinical data of 184 cases of community-acquired Staphylococcus aureus infections collected from 4 hospitals in Ningbo during May 2008 and May 2013 were reviewed.Microbial sensitivity test and virulence genes ( pvl and tst) detection were performed in clinical isolates, and SCCmec genotyping was performed in methicillin-resistant Staphylococcus aureus ( MRSA) strains.Binary logistic regression analysis was used to identify the risk factors for severe infections.Results Among 184 cases of community-acquired Staphylococcus aureus infections, 39 ( 21.20%) were severe cases. Staphylococcus aureus strains were highly resistant to penicillin, erythromycin and clindamycin, but more than 75% strains were sensitive to oxacillin, aminoglycosides, quinolones, rifampicin and vancomycin.Logistic regression analysis showed that advanced age (OR=1.024, 95%CI:1.005-1.043, P<0.05), malignant tumor (OR=15.288, 95%CI:1.609-145.229, P<0.05) , autoimmune diseases or long-term hormone therapy ( OR=12.102, 95%CI:2.082-70.338, P <0.01 ) were risk factors for severe community-acquired Staphylococcus aureus infections. Conclusions Strains isolated from the patients with community-acquired Staphylococcus aureus infections in Ningbo are usually sensitive to oxacillin, aminoglycosides, quinolones, rifampicin and vancomycin, which may be recommended for clinical use.Elder patients and those with malignant tumor, autoimmune diseases or long-term hormone therapy are more likely to develop severe Staphylococcus aureus infections.%目的:了解宁波地区社区获得性金黄色葡萄球菌重症感染发生的危险因素和菌株对常用抗菌药物的敏感性。方法连续收集2008年5月至2013年5月宁波地区4家医院184例社区获得性金黄色葡萄球菌感染病例的资料及分离的菌株。对患者一般特征(

    Full Text Available Background: Community-acquired pneumonia is a common reason for hospital admission; however underlying pathogens vary depending on host immunity and circulating pathogens in the community. Case Summary: A 32 year old man from Malawi presented with community-acquired pneumonia. After failing outpatient management, he was admitted and found to have underlying HIV disease. His diagnostic work up was initially inconclusive for M. tuberculosis (TB and thus his diagnostic evaluation and treatment focused on other etiologies. He was ultimately diagnosed with TB after an invasive procedure and had a rapid clinical response after initiating TB treatment. Conclusion: Both failure to recognize that TB can present with a syndrome similar to bacterial pneumonia and over-reliance on diagnostic testing delayed the diagnosis of TB. Delays in diagnosis contributed to substantial morbidity and risked nosocomial transmission. Despite declining incidence in the US, providers should remain cognizant of diagnostic limitations for TB disease and have a low threshold for empiric treatment.

    2015-05-01

    Community-acquired Acinetobacter baumannii (CA-Ab) is a rare but serious cause of community-acquired pneumonia in tropical regions of the world. CA-Ab infections predominantly affect individuals with risk factors, which include excess alcohol consumption, diabetes mellitus, smoking and chronic lung disease. CA-Ab pneumonia presents as a surprisingly fulminant course and is characterized by a rapid onset of fever, severe respiratory symptoms and multi-organ dysfunction, with a mortality rate reported as high as 64%. It is unclear whether the distinct clinical syndrome caused by CA-Ab is because of host predisposing factors or unique bacterial characteristics, or a combination of both. Deepening our understanding of the drivers of overwhelming CA-Ab infection will provide important insights into preventative and therapeutic strategies.

    A 53-year-old white man had fever, malaise, and dyspnea on exertion. His chest roentgenogram was normal, but pulmonary function tests showed impaired diffusion capacity and a gallium scan showed marked uptake in the lungs. Results of an open-lung biopsy documented Pneumocystis carinii pneumonia. Immunologic test results were consistent with the acquired immunodeficiency syndrome. The patient denied having homosexual contact or using intravenous drugs. Twenty-nine months before the diagnosis of pneumocystis pneumonia was made, the patient had had 16 transfusions of whole blood, platelets, and fresh-frozen plasma during coronary artery bypass surgery at another medical center. This patient is not a member of any currently recognized high-risk group and is believed to have contracted the acquired immunodeficiency syndrome from blood and blood-product transfusions.

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

  9. LiDAR data and SAR imagery acquired by an unmanned helicopter for rapid landslide investigation

    When earthquakes or heavy rainfall hits a landslide prone area, initial actions require estimation of the size of damage to people and infrastructure. This includes identifying the number and size of newly collapsed or expanded landslides, and appraising subsequent risks from remobilization of landslides and debris materials. In inapproachable areas, the UAV (Unmanned Aerial Vehicles) is likely to be of greatest use. In addition, repeat monitoring of sites after the event is a way of utilizing UAVs, particularly in terms of cost and convenience. In this study, LiDAR (SkEyesBox MP-1) data and SAR (Nano SAR) imagery, acquired over 0.5 km2 landslide prone area, are presented to assess the practicability of using unmanned helicopters (in this case a 10 year old YAMAHA RMAX G1) in these situations. LiDAR data was taken in July 2012, when tree foliage covered the ground surface. However, imagery was of sufficient quality to identify and measure landslide features. Nevertheless, LiDAR data obtained by a manned helicopter in the same area in August 2008 was more detailed, reflecting the function of the LiDAR scanner. On the other hand, 2 m resolution Nano SAR imagery produced reasonable results to elucidate hillslope condition. A quick method for data processing without loss of image quality was also investigated. In conclusion, the LiDAR scanner and UAV employed here could be used to plan immediate remedial activity of the area, before LiDAR measurement with a manned helicopter can be organized. SAR imagery from UAV is also available for this initial activity, and can be further applied to long term monitoring.

    2014-02-01

    The authors provide a transcription, translation, and evaluation of nine newly discovered letters from the alchemist Michael Maier (1568-1622) to Gebhardt Johann von Alvensleben (1576-1631), a noble landholder in the vicinity of Magdeburg. Stemming from the final year of his life, this correspondence casts new light on Maier's biography, detailing his efforts to secure patronage amid the financial crisis of the early Thirty Years' War. While his ill-fated quest to perfect potable gold continued to form the central focus of his patronage suits, Maier also offered his services in several arts that he had condemned in his printed works, namely astrology and "supernatural" magic. Remarks concerning his previously unknown acquaintance with Heinrich Khunrath call for a re-evaluation of Maier's negotiation of the discursive boundaries between Lutheran orthodoxy and Paracelsianism. The letters also reveal Maier's substantial contribution to a work previously ascribed solely to the English alchemist Francis Anthony.

    Objective To investigate the incidences, risk factors, genotypes and epidemiology of community-acquired blood stream infection caused by extended spectrum β-lactamases (ESBLs)-producing Escherichia coli and Klebsiella pneumonia strains and to analyze the sensitivity of those ESBLs producing strains to commonly used antibiotics. Methods Forty-two patients who were diagnosed with community-ac-quired blood stream infection caused by Escherichia coli or Klebsiella pneumonia strains in Sichuan Provincial People′s Hospital were recruited in this study. Disc diffusion method was used for the phenotypic confirmato-ry test of ESBLs. Agar dilution method was performed to measure the antimicrobial susceptibility of the ESBLs-producing strains to 13 clinically commonly used antibiotics. Genotypes of the ESBLs-producing strains were identified by polymerase chain reaction (PCR). Multilocus sequence typing (MLST) was used to analyze the epidemiology of ESBLs-producing strains. Logistic regression analysis was performed to analyze the risk factors for community-acquired blood stream infection. Results The ESBLs-producing Escherichia coli strains accounted for 56. 3% (18 / 32) and the ESBLs-producing Klebsiella pneumoniae strains accounted for 20% (2 / 10). All of the 20 ESBLs-producing strains were sensitive to imipenem, meropenem, ertapen-em, nitrofurantoin and moxalactam. The ESBLs-producing strains sensitive to amikacin, piperacillin-tazobactam and fosfomycin accounted for 95% , 90% and 85% , respectively. Drug resistance rates of the 20 strains to cefotaxime, levofloxacin, ciprofloxacin and cefepime were relatively high accounting for 100% , 80% , 80% and 75% , respectively. Among the 20 ESBLs-producing strains, 7 strains only carried the CTM gene, while the other 13 strains were all positive for two genotypes of ESBLs, mainly identified as TEM+CTM-M-14 and TEM+CTM-15 genotypes. The 18 Escherichia coli strains were classified into 10 ST types, most of which were ST131

    Acquired hemophilia A (AHA) is an autoimmune disease caused by an autoantibody to factor VIII. Patients are at risk of severe and fatal hemorrhage until the inhibitor is eradicated, and guidelines recommend immunosuppression as soon as the diagnosis has been made. The optimal immunosuppressive regimen is unclear; therefore, data from 331 patients entered into the prospective EACH2 registry were analyzed. Steroids combined with cyclophosphamide resulted in more stable complete remission (70%), defined as inhibitor undetectable, factor VIII more than 70 IU/dL and immunosuppression stopped, than steroids alone (48%) or rituximab-based regimens (59%). Propensity score-matched analysis controlling for age, sex, factor VIII level, inhibitor titer, and underlying etiology confirmed that stable remission was more likely with steroids and cyclophosphamide than steroids alone (odds ratio = 3.25; 95% CI, 1.51-6.96; P < .003). The median time to complete remission was approximately 5 weeks for steroids with or without cyclophosphamide; rituximab-based regimens required approximately twice as long. Immunoglobulin administration did not improve outcome. Second-line therapy was successful in approximately 60% of cases that failed first-line therapy. Outcome was not affected by the choice of first-line therapy. The likelihood of achieving stable remission was not affected by underlying etiology but was influenced by the presenting inhibitor titer and FVIII level.

    To delineate the clinical features and prognostic significance of acquired trisomy 21 (+21) in 31 patients with acute myeloid leukemia (AML). Chromosome specimen was prepared from bone marrow samples using a direct method and (or) cultivation, and their karyotypes were analyzed with R banding. The clinical features, chemotherapeutic effect and survival status of patients with acquired +21 were evaluated. Cytogenetic studies were successfully performed on 3 329 patients with newly diagnosed AML, among which 31 (0.93%) had acquired +21. And 16 (0.48%) of the 31 patients had +21 as the sole abnormality. The most frequent subgroup of bone marrow morphology was AML-M5b, and its total number was 12 (38.7%) of the total. Thirty patients among those with +21 received standard chemotherapy. The complete remission (CR) rate (63% vs. 80%, P 0.05). Three patients undergoing allogenetic hematopoietic stem cell transplantation (allo-HSCT) were still alive at the end of follow-up. Their survival time have reached 56, 36 and 105 months, respectively, which were remarkably longer than those only received chemotherapy (P< 0.01). The presence of acquired +21 in patients with AML has a adverse prognosis with or without other additional abnormalities. Older age (60 years or older) and +21 alone predicted relatively poorer outcome. Allo-HSCT was expected to prolong the survival time of AML patients with acquired +21.

    Full Text Available Judith E Karp1, Jeffrey E Lancet21Division of Hematologic Malignancies, Johns Hopkins Sidney Kimmel Comprehensive Cancer Center, Baltimore, Maryland, USA; 2H. Lee Moffitt Comprehensive Cancer Center, Tampa, Florida, USAAbstract: Farnesyltransferase inhibitors (FTIs represent a new class of signal transduction inhibitors that block the processing of cellular polypeptides that have cysteine terminal residues and, by so doing, interdict multiple pathways involved in proliferation and survival of diverse malignant cell types. Tipifarnib is an orally bioavailable, nonpeptidomimetic methylquinolone FTI that has exhibited clinical activity in patients with myeloid malignancies including elderly adults with acute myelogenous leukemia (AML who are not candidates for traditional cytotoxic chemotherapy, patients with high-risk myelodysplasia, myeloproliferative disorders, and imatinib-resistant chronic myelogenous leukemia. Because of its relatively low toxicity profile, tipifarnib provides an important alternative to traditional cytotoxic approaches for elderly patients who are not likely to tolerate or even benefit from aggressive chemotherapy. In this review, we will focus on the clinical development of tipifarnib for treatment of newly diagnosed AML, both as induction therapy for elderly adults with poor-risk AML and as maintenance therapy following achievement of first complete remission following induction and consolidation therapies for poor-risk AML. As with all other malignancies, the optimal approach is likely to lie in rational combinations of tipifarnib with cytotoxic, biologic and/or immunomodulatory agents with non-cross-resistant mechanisms of action. Gene expression profi ling has identified networks of differentially expressed genes and gene combinations capable of predicting response to single agent tipifarnib. The clinical and correlative laboratory trials in progress and under development will provide the critical foundations for

    New fluoride varnishes have been marketed that reportedly release more fluoride (Enamel Pro) or release fluoride more slowly (Vanish XT). The purpose of this study was to compare the amount and rate of fluoride release of new fluoride varnishes with other traditional fluoride varnishes. Extracted molars were cut into block sections. The enamel surfaces of the sections were painted with Enamel Pro, Duraphat, Vanish, or Vanish XT fluoride varnishes. One group was not treated and served as a negative control. The tooth sections were immersed in artificial saliva. The concentration of fluoride in parts per million was measured after the first 30 minutes, daily for the first week, and weekly until the level was below the limit of detection. Fluoride release was plotted over time. Cumulative fluoride release and rate of release (slope) were analyzed using one-way ANOVA/Tukey (α = .05). Enamel Pro had the greatest cumulative fluoride release. There was no significant difference between Duraphat and Vanish. Vanish XT had the lowest cumulative fluoride release. The rate of fluoride release from 1 week to limit of detection was Enamel Pro > Vanish > Duraphat > Vanish XT. The two newly marketed fluoride varnishes (Enamel Pro and Vanish XT) had significantly different fluoride release from the two conventional fluoride varnishes (Duraphat and Vanish).

    In this report, we describe a case of a neonatal oral herpes simplex virus (HSV) infection possibly acquired from a mother who had oral HSV reactivation in association with neuraxial morphine. Neuraxial morphine is commonly administered for postpartum analgesia after cesarean delivery. While there is evidence that neuraxial morphine increases the risks of oral HSV reactivation in parturients, there has been no report of neonatal HSV infection directly acquired from a mother who had HSV recurrence from neuraxial morphine.

    The impact of prolonging temozolomide (TMZ) maintenance beyond six cycles in newly diagnosed glioblastoma (GBM) remains a topic of discussion. We investigated the effects of prolonged TMZ maintenance on progression-free survival (PFS) and overall survival (OS). In this retrospective single-center cohort study, we included patients with GBM who were treated with radiation therapy with concomitant and adjuvant TMZ. For analysis, patients were considered who either completed six TMZ maintenance cycles (group B), continued with TMZ therapy beyond six cycles (group C), or stopped TMZ maintenance therapy within the first six cycles (group A). Patients with progression during the first six TMZ maintenance cycles were excluded. Clinical data from 107 patients were included for Kaplan-Meier analyses and 102 for Cox regressions. Median PFS times were 8.1 months (95% confidence interval [CI] 6.1-12.4) in group A, 13.7 months (95% CI 10.6-17.5) in group B, and 20.9 months (95% CI 15.2-43.5) in group C. At first progression, response rates of TMZ/lomustine rechallenge were 47% in group B and 13% in group C. Median OS times were 12.7 months (95% CI 10.3-16.8) in group A, 25.2 months (95% CI 17.7-55.5) in group B, and 28.6 months (95% CI 24.4-open) in group C. Nevertheless, multivariate Cox regression for patients in group C compared with group B that accounted for imbalances of other risk factors showed no different relative risk (RR) for OS (RR 0.77, p = .46). Our data do not support a general extension of TMZ maintenance therapy beyond six cycles. The Oncologist 2017;22:570-575 IMPLICATIONS FOR PRACTICE: Radiation therapy with concomitant and adjuvant temozolomide (TMZ) maintenance therapy is still the standard of care in patients below the age of 65 years in newly diagnosed glioblastoma. However, in clinical practice, many centers continue TMZ maintenance therapy beyond six cycles. The impact of this continuation is controversial and has not yet been addressed in

    Full Text Available There is limited evidence that long-term exposure to ambient air pollution increases the risk of childhood autism spectrum disorder (ASD. The objective of the study was to investigate the associations between long-term exposure to air pollution and newly diagnostic ASD in Taiwan. We conducted a population-based cohort of 49,073 children age less than 3 years in 2000 that were retrieved from Taiwan National Insurance Research Database and followed up from 2000 through 2010. Inverse distance weighting method was used to form exposure parameter for ozone (O3, carbon monoxide (CO, nitrogen dioxide (NO2, sulfur dioxide (SO2, and particles with aerodynamic diameter less than 10 µm (PM10. Time-dependent Cox proportional hazards (PH model was performed to evaluate the relationship between yearly average exposure air pollutants of preceding years and newly diagnostic ASD. The risk of newly diagnostic ASD increased according to increasing O3, CO, NO2, and SO2 levels. The effect estimate indicating an approximately 59% risk increase per 10 ppb increase in O3 level (95% CI 1.42-1.79, 37% risk increase per 10 ppb in CO (95% CI 1.31-1.44, 340% risk increase per 10 ppb increase in NO2 level (95% CI 3.31-5.85, and 17% risk increase per 1 ppb in SO2 level (95% CI 1.09-1.27 was stable with different combinations of air pollutants in the multi-pollutant models. Our results provide evident that children exposure to O3, CO, NO2, and SO2 in the preceding 1 year to 4 years may increase the risk of ASD diagnosis.

    Acquired cranial asymmetry is prevalent in infants today. This is largely attributed to the supine sleep position recommended for infant safety. The condition can become permanent, so prevention and early detection are important. A prevention project was initiated where guidelines for Swedish child health nurses were developed, tested in a pilot study, revised, and then incorporated into a short cranial asymmetry prevention program for nurses. The program included detailed information on what to teach parents of newborns. An intervention study was initiated where one group of nurses was taught according to the program and the other group followed the standard recommendations. The aim of this survey was to compare intervention and control group parents' responses regarding the cranial asymmetry prevention information that they had received from their nurses during their infant's first four months. Participants included 272 parents (180 intervention group, 92 control group) at 26 child health centers. A checklist was distributed to parents in conjunction with infants' four month health checkup. A significantly higher percentage of intervention group parents were aware of regular recommendations - alternate direction of the infant's head when putting the child to bed (82%: 64%, p=0.001), which pillow to use (92%: 80%, p=0.01), and when to remove the pillow (48%: 31%, p=0.006) - and five newly introduced recommendations compared to controls. Results indicate that educating child health nurses on prevention of cranial asymmetry works to increase parental awareness of what to do and how to do it safely.

    Community-acquired pneumonia (CAP) is not considered a professional disease, and the effect of different occupations and working conditions on susceptibility to CAP is unknown. The aim of this study is to determine whether different jobs and certain working conditions are risk factors for CAP. Over a 1-year period, all radiologically confirmed cases of CAP (n=1,336) and age- and sex-matched controls (n=1,326) were enrolled in a population-based case-control study. A questionnaire on CAP risk factors, including work-related questions, was administered to all participants during an in-person interview. The bivariate analysis showed that office work is a protective factor against CAP, while building work, contact with dust and sudden changes of temperature in the workplace were risk factors for CAP. The occupational factor disappeared when the multivariate analysis was adjusted for working conditions. Contact with dust (previous month) and sudden changes of temperature (previous 3 months) were risk factors for CAP, irrespective of the number of years spent working in these conditions, suggesting reversibility. Some recent working conditions such as exposure to dust and sudden changes of temperature in the workplace are risk factors for CAP. Both factors are reversible and preventable.

  20. Newly Identified Rydberg Emission Lines in Novae

    Newly Identified Rydberg Emission Lines in Novae David K. Lynch, Richard. J. Rudy (The Aerospace Corporation) & Lawrence S. Bernstein (Spectral Sciences, Inc.) Novae spectra in the near infrared frequently show a set of six emission lines that have not been positively identified (Williams, Longmore, & Geballe 1996, MNRAS, 279, 804; Lynch et al. 2001, AJ, 122, 2013; Rudy et al. 2002 ApJ, 573, 794; Lynch et al. 2004 Astron. J. 127, 1089-1097). These lines are at 0.8926, 1.1114, 1.1901, 1.5545, 2.0996 and 2.425 µm ± 0.005 µm. Krautter et al. (1984 A&A 137, 304) suggested that three of the lines were due to rydberg (hydrogenic) transitions in an unspecified atomic species that was in the 4th or 5th ionization stage (core charge = 4 & 5). We believe that Krautter et al.'s explanation is correct based on 4 additional lines that we have identified in the visible and near infrared spectrum of V723 Cassiopeiae. The observed Rydberg lines appear to originate from high angular momentum states with negligible quantum defects. The species cannot be determined with any certainty because in rydberg states, the outer electron sees a nucleus shielded by the inner electrons and together the inner atom appears to have a charge of +1, like hydrogen. As a result, the atom looks hydrogenic and species such as CV, NV, OV, MgV, SiV, etc. have their rydberg transitions at very similar wavelengths. All the lines represent permitted transitions, most likely formed by recombination. Atoms with core charges 4, 5 & 6 are rarely seen in the astrophysical environment because an extremely hot radiation field is necessary to ionize them. Thermonuclear runaways on the surface of a white dwarf can reach millions of degrees K, and thus there are enough X-ray photons available to achieve the necessary high ionization levels.

    Laboratory-acquired infections due to a variety of bacteria, viruses, parasites, and fungi have been described over the last century, and laboratory workers are at risk of exposure to these infectious agents. However, reporting laboratory-associated infections has been largely voluntary, and there is no way to determine the real number of people involved or to know the precise risks for workers. In this study, an international survey based on volunteering was conducted in biosafety level 3 and 4 laboratories to determine the number of laboratory-acquired infections and the possible underlying causes of these contaminations. The analysis of the survey reveals that laboratory-acquired infections have been infrequent and even rare in recent years, and human errors represent a very high percentage of the cases. Today, most risks from biological hazards can be reduced through the use of appropriate procedures and techniques, containment devices and facilities, and the training of personnel.

    The acquired alexia with agraphia syndrome is a conspicuous disorder of reading and writing in the absence of significant other language impairments that has mainly been recorded in adults. Pure cases are rare, with most patients displaying mild aphasic deficits. In children, acquired reading and writing disorders are generally reported as part of more encompassing aphasic syndromes affecting oral and written language equally, for example, Broca or Wernicke aphasia. Documented instances of predominant acquired reading and writing disorders in childhood are exceptional. We report an 11-year-old, right-handed boy who sustained a left temporoparieto-occipital hematoma following rupture of an arteriovenous malformation and who consecutively presented with the acquired alexia with agraphia syndrome associated with word-finding difficulties. Neuropsychologic and neurolinguistic data showed that there was no concomitant Gerstmann and/or angular gyrus syndrome. Th e recoveryfrom the anomia was quite favorable, but recovery of written language was more protracted and acted on the patient's further scholastic achievement. This case is reminiscent of a historical childhood case reported in 1939 and is consonant with adult cases in terms of lesion location and semiologic picture.

    Directory of Open Access Journals (Sweden)

    Full Text Available The prevalence of vancomycin-resistant enterococci (VRE colonization or infection in the hospital setting has increased globally. Many previous studies had analysed the risk factors for acquiring VRE, based on cross-sectional studies or prevalent cases. However, the actual incidence of and risk factors for VRE remain unclear. The present study was conducted in order to clarify the incidence of and risk factors for VRE in the intensive care unit (ICU. From 1(st April 2008 to 31(st March 2009, all patients admitted to a surgical ICU (SICU were put on active surveillance for VRE. The surveillance cultures, obtained by rectal swab, were taken on admission, weekly while staying in the SICU, and on discharge from the SICU. A total of 871 patients were screened. Among them, 34 were found to carry VRE before their admission to the SICU, and 47 acquired VRE during their stay in the SICU, five of whom developed VRE infections. The incidence of newly acquired VRE during ICU stay was 21.9 per 1000 patient-days (95% confidence interval [CI], 16.4-29.1. Using multivariate analysis by logistic regression, we found that the length of ICU stay was an independent risk factor for new acquisition of VRE. In contrast, patients with prior exposure to first-generation cephalosporin were significantly less likely to acquire VRE. Strategies to reduce the duration of ICU stay and prudent usage of broad-spectrum antibiotics are the keys to controlling VRE transmission.

  2. Circulating microparticles and endogenous estrogen in newly menopausal women.

    Estrogen modulates antithrombotic characteristics of the vascular endothelium and the interaction of blood elements with the vascular surface. A marker of these modulatory activities is formation of cell-specific microparticles. This study examined the relationship between blood-borne microparticles and endogenous estrogen at menopause. Platelet activation and plasma microparticles were characterized from women being screened (n = 146) for the Kronos Early Estrogen Prevention Study. Women were grouped according to serum estrogen ( 40 pg/ml; high estrogen, n = 11). Age, body mass index, blood pressure and blood chemistries were the same in both groups. No woman was hypertensive, diabetic or a current smoker. Platelet counts, basal and activated expression of P-selectin on platelet membranes were the same, but activated expression of glycoprotein IIb/IIIa was greater in the high-estrogen group. Numbers of endothelium-, platelet-, monocyte- and granulocyte-derived microparticles were greater in the low-estrogen group. Of the total numbers of microparticles, those positive for phosphatidylserine and tissue factor were also greater in the low-estrogen group. These results suggest that, with declines in endogenous estrogen at menopause, numbers of procoagulant microparticles increase and thus may provide a means to explore mechanisms for cardiovascular risk development in newly menopausal women.

    The prevalence of HIV/AIDS among people in midlife and late adulthood has been increasing in Western countries over the last decade. We analyzed data from a prospective, observational multi-centre study on individuals newly diagnosed with HIV between January 2004 and March 2007 in 10 public counselling and testing sites in Latium, Italy. At diagnosis, routine demographic, epidemiological, clinical and laboratory data are recorded, and patients are asked to complete a questionnaire investigating socio-demographic and psycho-behavioural aspects. To analyze the association of individual characteristics with age, we compared older adults (> or = 50 years) with their younger counterpart (18-49 years). To adjust for potential confounding effect of the epidemiological, clinical and behavioural characteristics, to identify factors associated with older age at HIV diagnosis, multivariate logistic regression analysis was performed. Overall, 1073 individuals were identified, 125 of whom (11.6%) were aged 50 years or above. The questionnaire was completed by 41% (440/1073). Compared with their younger counterparts, a higher proportion of older patients were males, born in Italy, reported heterosexual or unknown HIV risk exposure, were never tested for HIV before and were in a more advanced stage of HIV infection at diagnosis. In addition, older adults had a lower educational level and were more frequently living with their partners or children. With respect to psycho-behavioural characteristics, older patients were more likely to have paid money for sex and have never used recreational drugs. Interestingly, no differences were found regarding condom use, which was poor in both age groups. These findings may have important implications for the management of older adults with HIV, who should be targeted by appropriate public health actions, such as opportunistic screening and easier access to healthcare. Moreover, strategies including information on HIV and prevention of risk

    Jiménez P, Patricio; Calvo A, Mario

    2005-01-01

    Microbiological analysis allows us to identify the etiology of pneumonia and its in vitro susceptibility pattern. Antibiotic treatment directed against a known pathogen enables us to narrow antibacterial spectrum of action, and to reduce costs, drug adverse effects risk and antibiotic resistance. However it is unnecessary to perform extended microbiological studies in all patients with community acquired pneumonia (CAP). Etiological studies must be based in pneumonia severity, epidemiological risk factors and clinical response to empirical treatment. Routine microbiological analysis for ambulatory patients is not recommended. In patients with persistent cough and worsening in their general conditions, a sputum sample must be obtained to perform an acid-fast smear and Mycobacterium culture. The risk of complications and death of patients hospitalized with CAP justifies basic microbiological exploration (sputum Gram staining and culture, blood cultures, pleural fluid culture) intending to obtain a more accurate etiology of pulmonary infection and to guide specific antibiotic treatment. Paired serum samples obtained to document atypical pathogen infections (Mycoplasma pneumoniae, Chlamydia pneumoniae) and urine sample to detect Legionella pneumophila antigenuria are recommended in all CAP severely ill patients that are admitted to ICU, in those not responding to betalactamic drug treatment and in selected patients with specific epidemiological risks. A microbiological study would be useful in management of patients with severe CAP pneumonia outbreaks with clinical-epidemiological particular characteristics, and in-patients with empirical antimicrobial treatment failure.

    This study aims to investigate the risk of subsequent fractures after low-trauma fracture in frail older people. A total of 1412 elderly residents (mean age 86.2 years, SD 7.0 years, female 77%) were recruited from aged care facilities in Australia. Residents were assessed and then followed for any fracture for 2 years and hip fractures for at least 5 years. Residents with and without a newly acquired fracture in the first 2 years were compared for risk of subsequent hip fracture. Residents with a nonhip fracture in the first 2 years had an increased risk of subsequent hip fracture for about 2.5 years, whereas those with a hip fracture had a similar risk over the whole period compared with those with no fracture. During these 2.5 years, 60, 28, and 6 subsequent hip fractures occurred in the nonfracture group (n = 953), the nonhip fracture group (n = 194), and the hip fracture group (n = 101), respectively, resulting in the probability of subsequent hip fracture of 8.0%, 19.9%, and 10.4%, respectively. Compared with the nonfracture group, the hazard ratio (HR) was 2.82 [95% confidence interval (CI) 1.73-4.59; p < .001] for the nonhip fracture group and 1.48 (95% CI 0.63-3.49, p = .37) for the hip fracture group after adjusting for age, sex, residence type, calcaneal broadband ultrasound attenuation, fracture history, weight, lower leg length, immobility, cognitive function, and medications. Frail institutionalized older people with newly acquired fractures are at increased risk of subsequent hip fracture for the next few years. Accordingly, despite their advanced age, they are a high-priority target group to investigate interventions that might reduce the risk of hip fracture.

    2000-10-01

    Stuttering is an uncommon presentation of acute stroke. Reported cases have often been associated with left sided cortical lesions, aphasia, and difficulties with other non-linguistic tests of rhythmic motor control. Three patients with subcortical lesions resulting in stuttering are discussed. In one patient the ability to perform time estimations with a computerised repetitive time estimation task was characterised. One patient had a pontine infarct with clinical evidence of cerebellar dysfunction. A second patient had a left basal ganglionic infarct and a disruption of timing estimation. A third patient had a left subcortical infarct and a mild aphasia. These findings expand the reported distribution of infarction that can result in acquired stuttering. Subcortical mechanisms of speech control and timing may contribute to the pathophysiology of acquired stuttering.

    1985-01-01

    The electrophysiologic differences between chronic acquired demyelinative neuropathy and the demyelinative form of Charcot-Marie-Tooth disease have recently been reported. The present report extends these observations to include the genetically determined demyelinating neuropathies seen in metachromatic leukodystrophy, Krabbe's leukodystrophy, and Cockayne's syndrome. The electrophysiologic features of metachromatic leukodystrophy (five patients), Krabbe's (four patients), and Cockayne's syndrome (three patients) were all similar. There was uniform slowing of conduction (both in different nerves and in different nerve segments), and conduction block was not seen. These findings are consistent with a uniform degree of demyelination in multiple nerves and throughout the entire length of individual axons. Thus, uniform slowing of nerve conduction constitutes strong evidence for a familial demyelinative neuropathy, as opposed to the multifocal slowing seen in acute and chronic acquired demyelinative neuropathy.

  12. Recognising and managing community-acquired pneumonia.

    Science.gov (United States)

    Gibson, Vanessa

    2015-11-18

    Pneumonia remains a significant cause of morbidity and mortality in the UK and yet the seriousness of the disease is underestimated. Pneumonia can be life-threatening because the delicate tissues of the alveoli and pulmonary capillaries are susceptible to damage from the inflammatory response. This damage leads to consolidation that prevents the diffusion of oxygen and carbon dioxide, and this in turn can lead to respiratory failure. This article summarises guidance on the diagnosis and management of community-acquired pneumonia, and also includes information on the prevention of pneumonia. This information should be valuable to nurses working in a variety of clinical areas since patients with community-acquired pneumonia are encountered in primary, intermediate, secondary and critical care.

    Acquired brain injury (ABI) can result in impairments in motor function, language, cognition, and sensory processing, and in emotional disturbances, which can severely reduce a survivor's quality of life. Music interventions have been used in rehabilitation to stimulate brain functions involved in movement, cognition, speech, emotions, and sensory perceptions. An update of the systematic review published in 2010 was needed to gauge the efficacy of music interventions in rehabilitation for people with ABI. To assess the effects of music interventions for functional outcomes in people with ABI. We expanded the criteria of our existing review to: 1) examine the efficacy of music interventions in addressing recovery in people with ABI including gait, upper extremity function, communication, mood and emotions, cognitive functioning, social skills, pain, behavioural outcomes, activities of daily living, and adverse events; 2) compare the efficacy of music interventions and standard care with a) standard care alone, b) standard care and placebo treatments, or c) standard care and other therapies; 3) compare the efficacy of different types of music interventions (music therapy delivered by trained music therapists versus music interventions delivered by other professionals). We searched the Cochrane Stroke Group Trials Register (January 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) (2015, Issue 6), MEDLINE (1946 to June 2015), Embase (1980 to June 2015), CINAHL (1982 to June 2015), PsycINFO (1806 to June 2015), LILACS (1982 to January 2016), and AMED (1985 to June 2015). We handsearched music therapy journals and conference proceedings, searched dissertation and specialist music databases, trials and research registers, reference lists, and contacted relevant experts and music therapy associations to identify unpublished research. We imposed no language restriction. We performed the original search in 2009. We included all randomised controlled trials

    The purpose of this study was to characterize differences in the prevalence of hereditary and acquired thrombophilia in patients with splanchnic vein thrombosis (SVT). A total of 88 consecutive patients with SVT, including Budd Chiari Syndrome (n = 47) and portal extrahepatic portal vein obstruction (n = 41), underwent comprehensive thrombophilia testing, including testing for heritable and acquired causes. In 33 (37.5%) patients, etiology could be explained by at least 1 of the heritable etiologic factors, and 31 (35.2%) patients could be explained by at least 1 of the acquired causes studied. The combination of multiple concurrent factors was present in 9 (11.4%) patients. Among the heritable causes, the risk of SVT was found increased in the presence of thrombophilia resulting from the deficiencies of the naturally occurring anticoagulant proteins, and the acquired thrombogenic factors were significantly associated with causation of thrombosis in adult patients with SVT.

    A key feature of the vertebrate adaptive immune system is acquired immune memory, whereby hosts launch a faster and heightened response when challenged by previously encountered pathogens, preventing full infection. Here, we use a mathematical model to explore the role of ecological and epidemiological processes in shaping selection for costly acquired immune memory. Applying the framework of adaptive dynamics to the classic SIR (Susceptible-Infected-Recovered) epidemiological model, we focus on the conditions that may lead hosts to evolve high levels of immunity. Linking our work to previous theory, we show how investment in immune memory may be greatest at long or intermediate host lifespans depending on whether immunity is long lasting. High initial costs to gain immunity are also found to be essential for a highly effective immune memory. We also find that high disease infectivity and sterility, but intermediate virulence and immune period, increase selection for immunity. Diversity in host populations through evolutionary branching is found to be possible but only for a limited range of parameter space. Our model suggests that specific ecological and epidemiological conditions have to be met for acquired immune memory to evolve.

    Full Text Available Acquired hemophilia A is a rare, but devastating bleeding disorder caused by spontaneous development of autoantibodies directed against coagulation factor VIII. In 40%-50% of patients it is associated with such conditions as the postpartum period, malignancy, use of medications, and autoimmune diseases; however, its cause is unknown in most cases. Acquired hemophilia A should be suspected in patients that present with a coagulation abnormality, and a negative personal and family history of bleeding. Herein we report 3 patients with acquired hemophilia A that had different underlying pathologies, clinical presentations, and therapeutic responses. Factor VIII inhibitor formation in case 1 occurred 6 months after giving birth; underlying disorders were not identified in cases 2 or 3. The bleeding phenotype in these patients’ ranged from no bleeding tendency with isolated prolongation of APTT (activated partial thromboplastin time to severe intramuscular hematoma and hemarthrosis necessitating recombinant activated factor VII infusion and blood components transfusion. Variable responses to immunosuppressive treatment were also observed.

The literature contains a diverse range of biological and psychological etiological theories. Acquired PE is commonly due to sexual performance anxiety, psychological or relationship problems, erectile dysfunction (ED), and occasionally prostatitis and hyperthyroidism, consistent with the predominant organic etiology of acquired PE, men with this complaint are usually older, have a higher mean BMI and a greater incidence of comorbid disease including hypertension, sexual desire disorder, diabetes mellitus, chronic prostatitis, and ED compared to lifelong, variable and subjective PE.

    Acquired fetal brain damage is suspected in cases of destruction of previously normally formed tissue, the primary cause of which is hypoxia. Fetal brain damage may occur as a consequence of acute or chronic maternal diseases, with acute diseases causing impairment of oxygen delivery to the fetal brain, and chronic diseases interfering with normal, placental development. Infections, metabolic diseases, feto-fetal transfusion syndrome, toxic agents, mechanical traumatic events, iatrogenic accidents, and space-occupying lesions may also qualify as pathologic conditions that initiate intrauterine brain damage. MR manifestations of acute fetal brain injury (such as hemorrhage or acute ischemic lesions) can easily be recognized, as they are hardly different from postnatal lesions. The availability of diffusion-weighted sequences enhances the sensitivity in recognizing acute ischemic lesions. Recent hemorrhages are usually readily depicted on T2 (*) sequences, where they display hypointense signals. Chronic fetal brain injury may be characterized by nonspecific changes that must be attributable to the presence of an acquired cerebral pathology. The workup in suspected acquired fetal brain injury also includes the assessment of extra-CNS organs that may be affected by an underlying pathology. Finally, the placenta, as the organ that mediates oxygen delivery from the maternal circulation to the fetus, must be examined on MR images.

    The purpose of this work was to determine whether cross-sectional area and coronal and sagittal diameter measurements of the trachea between inspiration and end-expiration on CT are significantly different between patients with acquired tracheomalacia and those without this condition. Inspiratory and end-expiratory CT scans of the trachea of 23 normal patients and 10 patients with acquired tracheomalacia were analyzed. Percent changes in cross-sectional area, coronal, and sagittal diameters were calculated. For patients with tracheomalacia, mean percent changes in the upper and middle trachea between inspiration and expiration were 49 and 44%; mean changes in the coronal and sagittal diameters in the upper and middle tracheal were 4 and 10% and 39 and 54%, respectively. Control group mean percent changes in the upper and middle tracheal area were 12 and 14%, respectively, and mean changes in the coronal and sagittal diameters in the upper and middle trachea were 4 and 4% and 11 and 13%, respectively. Significant differences were calculated for changes in cross-sectional area and sagittal diameter between groups (p 18% change in the upper trachea and 28% change in the midtrachea between inspiration and expiration were observed; the probability of tracheomalacia was 89-100%. The probability of tracheomalacia was > 89%, especially if the change in sagittal diameter was > 28%. By measuring changes in tracheal cross-sectional area and sagittal diameters between inspiratory and end-expiratory CT, a significant difference can be identified between normal patients and those with acquired tracheomalacia.

    Full Text Available Background: community-acquired pneumonia is the leading cause of hospitalization among older adults. It has a high fatality rate. At present, there are several risk and prognosis scores and different clinical practice guidelines available. Objective: to develop a proposal for the management of community-acquired pneumonia in older adults, applicable in both primary care, and the hospital setting. Methods: a search on community-acquired pneumonia, especially in older adults or the elderly, was conducted using index terms and existing guidelines from different countries, companies and regional consensus included in Clinical Evidence, The Cochrane Library, PubMed, Google Scholar, MEDLINE, LIS, Scielo, Medscape, LILACS, Latindex, HINARI, MEDIGRAPHIC-NEWS and others. The publications providing high-quality evidence in accordance with the criteria of the Grading of Recommendations, Assessment, Development and Evaluations approach were selected. Results: a proposal for practical management of community-acquired pneumonia at any level of care in our health system was developed considering the list of medications currently available in the country. Epidemiology, risk factors, risk stratification, treatment, and fatality rate were considered. Conclusions: community-acquired pneumonia is a current problem and future challenge. This proposal can be used by professionals treating this condition at any level of care. Its application could improve care and quality of life and reduce the fatality rate and costs.

    Full Text Available Diabetic retinopathy is a common complication of type II diabetes mellitus and carries with it the threat of blindness. Accurate information regarding the incidence of diabetic retinopathy and associated risk factors is important in the prevention of its development and of the visual impairment caused by this complication. This study was designed to determine the prevalence of diabetic retinopathy in newly diagnosed patients with type II diabetes mellitus. We have also evaluated the association of diabetic retinopathy with clinical and biochemical variables. In a cross-sectional study, 152 consecutive patients with newly diagnosed type II diabetes mellitus were referred from two outpatient clinics in Tehran for ophthalmologic exam to detect retinopathy. Indirect ophthalmoscopy was performed and data regarding risk factors were extracted from routine medical records. Chi square and Mann Whitney U tests were used to analyze the data. The overall prevalence of diabetic retinopathy was 13.8 %( 21 cases: three cases with microaneurysm only, 10 with mild, 5 with moderate and 2 with severe non proliferative diabetic retinopathy. Only one patient had advanced proliferative retinopathy. The prevalence of diabetic retinopathy was positively associated with age, duration of disease, fasting plasma glucose, HbA1c, and systolic blood pressure. Diabetic retinopathy is common in newly diagnosed type II diabetes mellitus patients. Ophthalmologic consultation is essential at the time of diagnosis for all patients.

    Full Text Available The relationship between a perioperative change in sarcopenic status and clinical outcome of liver transplantation (LT is unknown. We investigated whether post-LT sarcopenia and changes in sarcopenic status were associated with the survival of patients.This retrospective study was based on a cohort of 145 patients from a single transplant center who during a mean of 1 year after LT underwent computed tomography imaging evaluation. The cross-sectional area of the psoas muscle of LT patients was compared with that of age- and sex-matched healthy individuals. The Cox proportional hazards regression model was used to determine whether post-LT sarcopenia and changes in sarcopenic status affect post-LT survival.The mean age at LT of the 116 male and 29 female patients was 50.2 ± 7.9 years; the mean follow-up duration was 51.6 ± 32.9 months. All pre-LT patients with sarcopenia still had sarcopenia 1 year after LT; 14 (15% patients had newly developed sarcopenia. The mean survival duration was 91.8 ± 4.2 months for non-sarcopenic patients and 80.0 ± 5.2 months for sarcopenic patients (log-rank test, p = 0.069. In subgroup analysis, newly developed sarcopenia was an independent negative predictor for post-LT survival (hazard ratio: 10.53, 95% confidence interval: 1.37-80.93, p = 0.024.Sarcopenia in LT recipients did not improve in any of the previously sarcopenic patients and newly developed within 1 year in others. Newly developed sarcopenia was associated with increased mortality. Newly developed sarcopenia can be used to stratify patients with regard to the risk of post-LT mortality.

    Objective To describe the clinical features of reported cases of community-acquired pneumonia (CAP) due to methicillin-resistant Staphylococcus aureus (MRSA), and to evaluate the risk factors related to outcome. Methods A systematic search of databases from January 1995 to December 2009 was performed. Baseline characteristics of survivors and non-survivors in the hospital were compared with the χ2 test for categorical variables. Variables with P<0.2 were entered in Logistic regression. Survival analysis was estimated by the Kaplan-Meier method according to use of antimicrobials inhibiting toxin production. Results Fifty-two articles were identified reporting data on 74 patients, with 41.1% of total mortality, short duration of symptom onset to death [(6.1±11.0) days], and prolonged hospital admissions [(28.6±29.1) days]. Logistic regression analysis showed that influenza like symptoms (P=0.04), hemoptysis (P<0.01), leucopenia (P<0.01) were the risk factors associated with death, and using clindamycin or linezolid which could inhibit the Panton-Valentine leukocidin (PLV, P<0.01) was the factor associated with survival. Kaplan-Meier analysis indicated that the antibiotic therapies inhibiting toxin production were associated with improved outcome in these cases (χ2=21.59, P<0.01). Conclusion CAP due to MRSA is a severe disease with significant lethality. Empiric therapy of severe CAP with flu-like symptoms, hemoptysis and leucopenia should include coverage for MRSA. Targeted treatment with antimicrobials inhibiting toxin production appear to be more appropriate selection.%目的 揭示社区获得性耐甲氧西林金黄色葡萄球菌(CA-MRSA)肺炎临床特征及死亡相关危险因素.方法 系统检索1995年1月至2009年12月发表的中英文文献,对比分析CA-MRSA肺炎生存和死亡者的临床特征,对相关参数进行Logistic回归分析以探讨与死亡的关系.按照是否应用抑制杀白细胞素(PVL)治疗措施分层,对患

    Objective To investigate the clinical features, risk factors, antibiotic resistance, and clinical outcomes of hospital-acquired pneumonia ( HAP) in adult patients in Shanghai hospitals. Methods From November 2007 to December 2009, the clinical and microbiological data of HAP cases were prospectively reviewed in seven large general hospitals in Shanghai region. Results A total of 204 cases were included in the analysis. The mean age of these patients was (68 ± 17) years (58. 3%>70 years). The underlying conditions included cerebral vascular disease, diabetes mellitus and abdominal surgery. Ventilator-associated pneumonia accounted for 20.6% of the cases. The case mortality was 15. 7%. Increased heart rate, decreased arterial PH, hypoxia, hyperglycemia, increased plasma creatinine and vasopressor use were associated with the poor outcome in these HAP patients. Of all the bacterial strains isolated from HAP, 64.9% were gram-negative bacilli, including A. Baumannii, P. Aeruginosa, K. Pneumoniae, and E. Colt. The prevalence of methicillin-resistant Staphylococcus aureus was 65. 4% in the S. Aureus isolates. No vancomycin-resistant MRSA was identified. Conclusions Advanced age, cerebrovascular diseases and diabetes are risk factors of HAP. Septic shock is the most important complication associated with poor prognosis of HAP. Common pathogens of HAP include A. Baumannii, P. Aeruginosa, K. Pneumoniae, E. Coli, and S. Aureus (MRSA 65.4%).%目的 本研究对上海地区医院获得性肺炎(HAP)的病原菌和临床结局进行前瞻性研究,探讨上海地区HAP的临床特点、易患因素、病原菌的耐药状况及对临床预后的影响因素.方法 采用前瞻性观察性研究方法,收集2007年11月-2009年12月上海市7所大型综合性医院住院并确诊为HAP患者的临床资料及微生物学标本进行细菌培养、鉴定和药敏试验.结果 本组共收集HAP 204例,患者平均年龄(68±17)岁,70岁以上患者占58.3%.患者的基础疾病

    Objectives. We conducted a large-scale study of newly arrived refugee children in the United States with data from 2006 to 2012 domestic medical examinations in 4 sites: Colorado; Minnesota; Philadelphia, Pennsylvania; and Washington State. Methods. Blood lead level, anemia, hepatitis B virus (HBV) infection, tuberculosis infection or disease, and Strongyloides seropositivity data were available for 8148 refugee children (aged Malaysia. Hepatitis B was more prevalent among male children than female children and among children aged 5 years and older. The odds of HBV, tuberculosis, and Strongyloides decreased over the study period. Conclusions. Medical screening remains an important part of health care for newly arrived refugee children in the United States, and disease risk varies by population. PMID:26562126

    The aim of this study was to review recent advances in the management of acquired cholesteatoma. All papers referring to acquired cholesteatoma management were identified in Medline via OVID (1948 to December 2013), PubMed (to December 2013), and Cochrane Library (to December 2013). A total of 86 papers were included in the review. Cholesteatoma surgery can be approached using either a canal wall up (CWU) or canal wall down (CWD) mastoidectomy with or without reconstruction of the middle ear cleft. In recent decades, a variety of surgical modifications have been developed including various "synthesis" techniques that combine the merits of CWU and CWD. The application of transcanal endoscopy has also recently gained popularity; however, difficulties associated with this approach remain, such as the need for one-handed surgery, the inability to provide continuous irrigation/suction, and limitations regarding endoscopic accessibility to the mastoid cavity. Additionally, several recent studies have reported successes in the application of laser-assisted cholesteatoma surgery, which overcomes the conflicting goals of eradicating disease and the preservation of hearing. Nevertheless, the risk of residual disease remains a challenge. Each of the techniques examined in this study presents pros and cons regarding final outcomes, such that any pronouncements regarding the superiority of one technique over another cannot yet be made. Flexibility in the selection of surgical methods according to the context of individual cases is essential in optimizing the outcomes.

    Full Text Available Following a large outbreak of community-acquired psittacosis in 2002 in residents of the Blue Mountains, New South Wales, Australia, we reviewed new cases in this area over a 7-year period from 2003 to 2009. Using the 2010 criteria from the Centers for Disease Control National Notifiable Diseases Surveillance System, 85 patients with possible psittacosis were identified, of which 48 were identified as definite or probable infection. Clinical features of these cases are summarized. In addition to Chlamydia-specific serology, specimens, where available, underwent nucleic acid testing for chlamydial DNA using real-time PCR. Chlamydophila psittaci DNA was detected in samples from 23 patients. Four of 18 specimens were culture positive. This is the first description of endemic psittacosis, and is characterized in this location by community-acquired psittacosis resulting from inadvertent exposure to birds. The disease is likely to be under-diagnosed, and may often be mistaken for gastroenteritis or meningitis given the frequency of non-respiratory symptoms, particularly without a history of contact with birds. Clinical characteristics of endemic and outbreak-associated cases were similar. The nature of exposure, risk factors and reasons for the occurrence of outbreaks of psittacosis require further investigation.

    We investigated the association between antipsychotic medications and the risk of dental caries in patients with schizophrenia. We enroled a nationwide cohort of patients with newly diagnosed schizophrenia within 1 year of dental caries development. Exposure to antipsychotics and other medications was categorised according to their type and duration, and the association between exposure and dental caries was assessed through logistic regressions. Of the 3610 patients with newly diagnosed schizophrenia, 2149 (59.5%) exhibited an incidence of treated dental caries. Logistic regression analysis identified a younger age, female sex, high income, a 2-year history of dental caries, and exposure to first-generation antipsychotics, and antihypertensives as independent risk factors for treated dental caries in patients with schizophrenia. Hyposalivation, the adverse effect of first-generation antipsychotics and antihypertensives, was associated with an increased risk of treated dental caries. However, hypersalivation from first-generation antipsychotics for dental caries was associated with a protective factor. These findings suggest that clinicians should pay attention to the aforementioned risk factors for dental caries in patients with schizophrenia, particularly while prescribing first-generation antipsychotics and antihypertensives to such patients.

    Methods:The newly developed device consists of two parts:the plunger and barrel. On one side, the barrel is bullet shaped with an opening tip. The plunger is located in the middle cavity of the tube barrel and extended out at the open-end. It was designed for strengthening the tube barrel and for convenience in performing the drainage procedure. It can be used by inserting the drainage tube into the lesion and pulling out the plunger, whereby blood will forcefully rise up inside the barrel, providing a satisfactory outcome. It is made for effusion drainage purposes. During the procedure, the drainage tip is placed at the deepest part of the intracranial hematoma to completely drain the blood. Moreover, the plunger fits tightly in the tube, preventing leakage during the operation. With the use of the device, brain can be separated. In addition, the device can help reduce the risk of cerebral damage because of the small operating area. The barrel sidewall has matching opening holes bilaterally and equally for exchanging substances between the inner and outer parts. The overlapping ratio in each horizontal pair is around 1/3–1/2. Each pair on the opposite side will form a different pressure. Thus, the opening holes will not easily get blocked with blood clot. Results: Blood and accumulated liquid from the deepest part of the intracranial hematoma can be directly drawn through the drainage tube without damaging a large area. The tube does not get blocked easily and allows for complete removal of the hematoma. Conclusions:The device is asuitable instrument for clinical application.

    2014-06-01

    Full Text Available Acquired immunodeficiency syndrome (AIDS is a human immune system disease characterized by increased susceptibility to opportunistic infections, certain cancers and neurological disorders. The syndrome is caused by the human immunodeficiency virus (HIV that is transmitted through blood or blood products, sexual contact or contaminated hypodermic needles. Antiretroviral treatment reduces the mortality and the morbidity of HIV infection but is increasingly reported to be associated with increasing reports of metabolic abnormalities. The prevalence and incidence of diabetes mellitus in patients on antiretroviral therapy is high. Recently, a joint panel of American Diabetes Association (ADA and European Association for the Study of Diabetes (EASD experts updated the treatment recommendations for type 2 diabetes (T2DM in a consensus statement which provides guidance to health care providers. The ADA and EASD consensus statement concur that intervention in T2DM should be early, intensive, and uncompromisingly focused on maintaining glycemic levels as close as possible to the nondiabetic range. Intensive glucose management has been shown to reduce microvascular complications of diabetes but no significant benefits on cardiovascular diseases. Patients with diabetes have a high risk for cardiovascular disease and the treatment of diabetes should emphasize reduction of the cardiovascular factors risk. The treatment of diabetes mellitus in AIDS patients often involves polypharmacy, which increases the risk of suboptimal adherence

    Full Text Available Arjun Gupta, Sahil Khanna Division of Gastroenterology and Hepatology, Mayo Clinic, Rochester, MN, USA Abstract: There has been a startling shift in the epidemiology of Clostridium difficile infection over the last decade worldwide, and it is now increasingly recognized as a cause of diarrhea in the community. Classically considered a hospital-acquired infection, it has now emerged in populations previously considered to be low-risk and lacking the traditional risk factors for C. difficile infection, such as increased age, hospitalization, and antibiotic exposure. Recent studies have demonstrated great genetic diversity for C. difficile, pointing toward diverse sources and a fluid genome. Environmental sources like food, water, and animals may play an important role in these infections, apart from the role symptomatic patients and asymptomatic carriers play in spore dispersal. Prospective strain typing using highly discriminatory techniques is a possible way to explore the suspected diverse sources of C. difficile infection in the community. Patients with community-acquired C. difficile infection do not necessarily have a good outcome and clinicians should be aware of factors that predict worse outcomes in order to prevent them. This article summarizes the emerging epidemiology, risk factors, and outcomes for community-acquired C. difficile infection.

    Highlights: • CT with multiplanar reformations can accurately display the sigmoid platet dehiscence. • The prevalence of sigmoid plate dehiscence was no significant difference among different age groups. • The size of sigmoid plate bony defects were not statistically different among different age groups. • The sigmoid plate dehiscence is more commonly a congenital than an acquired condition. - Abstract: Background and purpose: The imaging features of sigmoid plate dehiscence-induced pulsatile tinnitus have been presented. The origin of the sigmoid plate dehiscence, however, remains unclear. Our aim was to assess the prevalence and extent of sigmoid plate dehiscence on computed tomography (CT) images in multiple age groups to determine whether this condition is more likely to be congenital or acquired. Materials and methods: We retrospectively reviewed contrast-enhanced CT images of sigmoid plates of temporal bones in 504 patients. Each temporal bone was characterized as normal or dehiscent. Patients were then subcategorized into four age groups, and the prevalence and extent of dehiscent sigmoid plates in each group were calculated and compared. Results: Overall, 80 patients had sigmoid plate dehiscence, nine of whom had it bilaterally. In successively older age groups, the prevalences of sigmoid plate dehiscence were 18.9%, 20.1%, 14.5%, and 12.7%, respectively. Respective average anteroposterior bony defect diameters were 3.7 ± 1.7, 3.0 ± 1.3, 3.1 ± 1.5, and 3.0 ± 1.1 mm. Respective average vertical bony defect diameters were 3.6 ± 2.3, 2.6 ± 1.2, 3.2 ± 1.5, and 3.0 ± 1.7 mm. The prevalence and extent of sigmoid plate dehiscence were not statistically different among the four age groups. Conclusions: The similar radiologic prevalence and extent of dehiscent sigmoid plates among the age groups suggest that the dehiscence is more commonly a congenital than an acquired condition.

  15. Acquired prosopagnosia without word recognition deficits.

    It has long been suggested that face recognition relies on specialized mechanisms that are not involved in visual recognition of other object categories, including those that require expert, fine-grained discrimination at the exemplar level such as written words. But according to the recently proposed many-to-many theory of object recognition (MTMT), visual recognition of faces and words are carried out by common mechanisms [Behrmann, M., & Plaut, D. C. ( 2013 ). Distributed circuits, not circumscribed centers, mediate visual recognition. Trends in Cognitive Sciences, 17, 210-219]. MTMT acknowledges that face and word recognition are lateralized, but posits that the mechanisms that predominantly carry out face recognition still contribute to word recognition and vice versa. MTMT makes a key prediction, namely that acquired prosopagnosics should exhibit some measure of word recognition deficits. We tested this prediction by assessing written word recognition in five acquired prosopagnosic patients. Four patients had lesions limited to the right hemisphere while one had bilateral lesions with more pronounced lesions in the right hemisphere. The patients completed a total of seven word recognition tasks: two lexical decision tasks and five reading aloud tasks totalling more than 1200 trials. The performances of the four older patients (3 female, age range 50-64 years) were compared to those of 12 older controls (8 female, age range 56-66 years), while the performances of the younger prosopagnosic (male, 31 years) were compared to those of 14 younger controls (9 female, age range 20-33 years). We analysed all results at the single-patient level using Crawford's t-test. Across seven tasks, four prosopagnosics performed as quickly and accurately as controls. Our results demonstrate that acquired prosopagnosia can exist without word recognition deficits. These findings are inconsistent with a key prediction of MTMT. They instead support the hypothesis that face

    Most individuals who have survived an acquired brain injury present consequences affecting the sensorimotor, cognitive, affective or behavioural components. These deficits affect the proper performance of daily living activities. The aim of this study is to identify functional differences between individuals with unilateral acquired brain injury using functional independence, capacity, and performance of daily activities. Descriptive cross-sectional design with a sample of 58 people, with right-sided injury (n=14 TBI; n=15 stroke) or left-sided injury (n = 14 TBI, n = 15 stroke), right handed, and with a mean age of 47 years and time since onset of 4 ± 3.65 years. The functional assessment/functional independence measure (FIM/FAM) and the International Classification of Functioning (ICF) were used for the study. The data showed significant differences (P<.000), and a large size effect (dr=0.78) in the cross-sectional estimates, and point to fewer restrictions for patients with a lesion on their right side. The major differences were in the variables 'speaking' and 'receiving spoken messages' (ICF variables), and 'Expression', 'Writing' and 'intelligible speech' (FIM/FAM variables). In the linear regression analysis, the results showed that only 4 FIM/FAM variables, taken together, predict 44% of the ICF variance, which measures the ability of the individual, and up to 52% of the ICF, which measures the individual's performance. Gait alone predicts a 28% of the variance. It seems that individuals with acquired brain injury in the left hemisphere display important differences regarding functional and communication variables. The motor aspects are an important prognostic factor in functional rehabilitation. Copyright © 2013 Sociedad Española de Neurología. Published by Elsevier España, S.L.U. All rights reserved.

    The primary goal of triple arthrodesis for stage III and IV adult acquired flatfoot is to obtain a well-aligned plantigrade foot that will support the ankle in optimal alignment. Ancillary procedures including posterior muscle group lengthening, medial displacement calcaneal osteotomy, medial column stabilization, peroneus brevis tenotomy, or transfer and harvest of regional bone graft are often necessary to achieve adequate realignment. Image intensification is helpful in confirming optimal realignment before fixation. Results of triple arthrodesis are enhanced with adequate preparation of joint surfaces, bone graft/orthobiologics, 2-point fixation of all 3 tritarsal joints, and a vertical heel position.

    The face is a vital component of one’s personality and body image. There are a vast number of variables that influence recovery and rehabilitation from acquired facial trauma many of which are psychological in nature. The present paper presents the various psychological issues one comes across in facial trauma patients. These may range from body image issues to post-traumatic stress disorder symptoms accompanied by anxiety and depression. Issues related to facial and body image affecting social life and general quality of life are vital and the plastic surgeon should be aware of such issues and competent to deal with them in patients and families.

    Full Text Available Acquired hypopigmentary disorders comprise a significant group of disorders that affect Indians and Asians. The pigment disturbance in darker skin individuals can be very distressing to the patient and the family. These disorders cover a wide array of pathologies including infections, autoimmune processes, lymphoproliferative disorders, and sclerosing diseases. Histological diagnosis is particularly important because treatments for these diseases are varied and specific. This review will focus on histopathological diagnosis based on clinicopathological correlation for commonly encountered disorders such as leprosy, vitiligo, lichen sclerosus, pityriasis alba (PA, and pityriasis versicolor (PV. Atypical or uncommon clinical presentation of classic diseases such as hypopigmented mycosis fungoides (HMF and hypopigmented sarcoidosis are also included.

    Horner's syndrome (HS) is related to an interruption of the oculosympathetic nerve pathway. The classic clinical findings associated with this condition are ptosis, miosis, and enophthalmos. Heterochromia is typically described in congenital HS, but it is an uncommon finding in acquired HS. We report a case of post-traumatic HS associated with heterochromia. A literature review indicates that this type of heterochromia may be related to a reduction in the number of iris melanocytes. This mechanism may be the same in the physiological iris color modifications in adulthood.

    Plate-like osteoma cutis is a rare disorder that has been historically classified as a congenital syndrome. It has a possible relationship to a mutation in the gene (GNAS1) that encodes the α-subunit of the stimulatory G protein, which regulates adenyl cyclase activity. We report a case of extensive plaque-like masses on the scalp and face with no abnormalities in calcium or phosphate metabolism and no preceding inflammatory cutaneous conditions. With less than ten reported cases, to our knowledge, this is one the few cases of acquired plate-like osteoma cutis described in the literature.

    2003-01-01

    PIV Acquisition (PIVACQ) is a computer program for acquisition of data for particle-image velocimetry (PIV). In the PIV system for which PIVACQ was developed, small particles entrained in a flow are illuminated with a sheet of light from a pulsed laser. The illuminated region is monitored by a charge-coupled-device camera that operates in conjunction with a data-acquisition system that includes a frame grabber and a counter-timer board, both installed in a single computer. The camera operates in "frame-straddle" mode where a pair of images can be obtained closely spaced in time (on the order of microseconds). The frame grabber acquires image data from the camera and stores the data in the computer memory. The counter/timer board triggers the camera and synchronizes the pulsing of the laser with acquisition of data from the camera. PIVPROC coordinates all of these functions and provides a graphical user interface, through which the user can control the PIV data-acquisition system. PIVACQ enables the user to acquire a sequence of single-exposure images, display the images, process the images, and then save the images to the computer hard drive. PIVACQ works in conjunction with the PIVPROC program which processes the images of particles into the velocity field in the illuminated plane.

    People with communication impairments may face barriers to civic participation, with resulting marginalisation of individuals who wish to be actively involved. The investigation aimed to explore the experience of civically engaged adults with acquired neurological communication difficulties. Six people with acquired neurological communication difficulties were interviewed. Discussion included the definition of active citizenship, their civic involvement, motivations, related barriers and facilitators. Qualitative analysis was undertaken, with data categorised, coded and examined for recurring themes. All participants were active in disability-related organisations and four undertook wider civic roles. Motivations included activity being out with the home and wanting to effect change for themselves and the populations they represented. Disability group meetings were more positive experiences than broader community activities, which were associated with fatigue and frustration, commonly resulting from communication difficulties and unmet support needs. All participants identified a need for professional and public educational about disability and communication and made recommendations on content, methods and priority groups. For these participants civic engagement had positive and negative dimensions. Speech and language therapists should promote reduction of the barriers that impede the active citizenship rights of people with communication support needs. Civic participation may be a relevant measure of outcome in communication impaired populations.

    Community-acquired pneumonia is the sixth leading cause of death in the USA. Adherence to the 2007 Infectious Diseases Society of America/American Thoracic Society community-acquired pneumonia guidelines has been associated with improved clinical outcomes. However, choice between guideline-recommended treatments is at the discretion of the prescribing clinician. This review is intended to discuss the characteristics of these treatment options including dosing frequency, dose adjustment for renal/hepatic dysfunction, serious/common adverse events, drug interactions, lung penetration, pharmacokinetic-pharmacodynamic target and effect of obesity to help guide antimicrobial selection. An increasing portion of patients are receiving expanded empiric coverage for methicillin-resistant Staphylococcus aureus as recommended by the American Thoracic Society and Infectious Diseases Society of America for healthcare-associated pneumonia. However, this expanded coverage may not be achieving the desired improvements in clinical outcomes. We expect this increasingly diverse spectrum of patients with pneumonia to eventually result in the merger of these two guidelines to include all patients with pneumonia.

    Many animals acquire otherwise inaccessible food with the aid of sticks and occasionally water. As an exception, some reports suggest that elephants manipulate breathing through their trunks to acquire inaccessible food. Here, we report on two female Asian elephants (Elephas maximus) in Kamine Zoo, Japan, who regularly blew to drive food within their reach. We experimentally investigated this behaviour by placing foods in inaccessible places. The elephants blew the food until it came within accessible range. Once the food was within range, the elephants were increasingly less likely to blow as the distance to the food became shorter. One subject manipulated her blowing duration based on food distance: longer when the food was distant. These results suggest that the elephants used their breath to achieve goals: that is, they used it not only to retrieve the food but also to fine-tune the food position for easy grasping. We also observed individual differences in the elephants' aptitude for this technique, which altered the efficiency of food acquisition. Thus, we added a new example of spontaneous behaviour for achieving a goal in animals. The use of breath to drive food is probably unique to elephants, with their dexterous trunks and familiarity with manipulating the act of blowing, which is commonly employed for self-comfort and acoustic communication.

  8. Borders and Legal Criteria for Acquiring Nationality

    Directory of Open Access Journals (Sweden)

    2008-09-01

    Full Text Available Legal criteria for acquiring nationality are crucial in the integration of persons into society, since they provide access to the right to vote. Until now, the criteria most frequently used are those of ius soli (birth and ius sanguinis (nationality is inherited from the parents, which comply with previous anthropological approaches and which jurists accept without reflection, or consider to be unshakeable traditions.The author’s proposal in this article is to accept that some of these legal criteria should be reformed, though not in an anarchic manner. On one hand, some of the ethnic criteria may be respected, but on the other, the processes of acquiring nationality should be streamlined by accepting the desire of persons wanting to change their nationality on moving to a new country of residence. Meanwhile, we must establish channels of demand for accepting the democratic values and legal system of the welcoming country, as a result of which it would be fair to call for a prior learning period before the rights to nationality and suffrage are granted. The author also adds – and accepts as being a fundamental element – some of Habermas’ inclusion theses, though she stresses that this discourse should be organised into two specific, feasible legal solutions or rather, in a realistic manner.

    Full Text Available Acquired pigmentary disorders are group of heterogenous entities that share single, most significant, clinical feature, that is, dyspigmentation. Asians and Indians, in particular, are mostly affected. Although the classic morphologies and common treatment options of these conditions have been reviewed in the global dermatology literature, the value of histpathological evaluation has not been thoroughly explored. The importance of accurate diagnosis is emphasized here as the underlying diseases have varying etiologies that need to be addressed in order to effectively treat the dyspigmentation. In this review, we describe and discuss the utility of histology in the diagnostic work of hyperpigmentary disorders, and how, in many cases, it can lead to targeted and more effective therapy. We focus on the most common acquired pigmentary disorders seen in Indian patients as well as a few uncommon diseases with distinctive histological traits. Facial melanoses, including mimickers of melasma, are thoroughly explored. These diseases include lichen planus pigmentosus, discoid lupus erythematosus, drug-induced melanoses, hyperpigmentation due to exogenous substances, acanthosis nigricans, and macular amyloidosis.

  10. [Neural mechanism underlying autistic savant and acquired savant syndrome].

    2008-07-01

    It is well known that the cases with savant syndrome, demonstrate outstanding mental capability despite coexisting severe mental disabilities. In many cases, savant skills are characterized by its domain-specificity, enhanced memory capability, and excessive focus on low-level perceptual processing. In addition, impaired integrative cognitive processing such as social cognition or executive function, restricted interest, and compulsive repetition of the same act are observed in savant individuals. All these are significantly relevant to the behavioral characteristics observed in individuals with autistic spectrum disorders (ASD). A neurocognitive model of savant syndrome should explain these cognitive features and the juxtaposition of outstanding talents with cognitive disabilities. In recent neuropsychological studies, Miller (1998) reported clinical cases of "acquired savant," i.e., patients who improved or newly acquired an artistic savant-like skill in the early stage of frontotemporal dementia (FTD). Although the relationship between an autistic savant and acquired savant remains to be elucidated, the advent of neuroimaging study of ASD and the clarification of FTD patients with savant-like skills may clarify the shared neural mechanisms of both types of talent. In this review, we classified current cognitive models of savant syndrome into the following 3 categories. (1) A hypermnesic model that suggests that savant skills develop from existing or dormant cognitive functions such as memory. However, recent findings obtained through neuropsychological examinations imply that savant individuals solve problems using a strategy that is fairly different from a non-autistic one. (2) A paradoxical functional facilitation model (Kapur, 1996) that offers possible explanations about how pathological states in the brain lead to development of prodigious skills. This model emphasizes the role of reciprocal inhibitory interaction among adjacent or distant cortical regions

    Purpose The heterogeneous nature of myelodysplastic syndromes (MDS) complicates therapeutic decision making, particularly for newly diagnosed disease. Factors impacting the treatment plan in this early period of disease course are poorly defined. This study determines whether therapeutic choices for newly diagnosed MDS are associated with location of treatment (community or academic), prognostic risk category, and patient age. Methods The Adults in Minnesota with Myelodysplastic Syndromes (AIMMS) database was utilized in this statewide, prospective population-based study conducted by the University of Minnesota (UMN), Mayo Clinic, and Minnesota Department of Health. Adult (age 20+ years) cases of MDS newly diagnosed starting in April 2010 were invited to participate. This analysis includes patients enrolled during the first study year with one-year follow-up data. Treatment choices (supportive, active, and transplant) were stratified by the international prognostic scoring system (IPSS) and the revised-IPSS (IPSS-R), then separated into groups by location of care and age (<65 or 65+ years). Academic-based care was any contact with the UMN and Mayo Clinic; community-based care was all other clinical sites. Results Stratification by IPSS and IPSS-R showed supportive care decreased and active care increased with advancing risk categories (p <0.0001). Comparing treatment setting, community-based care had 77% supportive and 23% active treatment; academic-based care was 36% supportive, 41% active, and 23% transplant (p <0.0001). By age groups, patients <65 years with intermediate, high, or very high risk disease by IPSS-R received 97% active care/transplant, compared to only 52% of patients age 65+. Conclusions Younger patients and those treated at academic centers had a more aggressive treatment approach. Whether these treatment differences convey improved disease control and mortality, and therefore should be extended more frequently to older and community

    Acute promyelocytic leukemia (APL) is a curable subtype of acute myeloid leukemia. The optimum regimen for newly diagnosed APL remains inconclusive. In this Bayesian network meta-analysis, we compared the effectiveness of five regimens-arsenic trioxide (ATO) + all-trans retinoic acid (ATRA), realgar-indigo naturalis formula (RIF) which contains arsenic tetrasulfide + ATRA, ATRA + anthracycline-based chemotherapy (CT), ATO alone and ATRA alone, based on fourteen randomized controlled trials (RCTs), which included 1407 newly diagnosed APL patients. According to the results, the ranking efficacy of the treatment, including early death and complete remission in the induction stage, was the following: 1. ATO/RIF + ATRA; 2. ATRA + CT; 3. ATO, and 4. ATRA. For long-term benefit, ATO/RIF + ATRA significantly improved overall survival (OS) (hazard ratio = 0.35, 95%CI 0.15-0.82, p = 0.02) and event-free survival (EFS) (hazard ratio = 0.32, 95%CI 0.16-0.61, p = 0.001) over ATRA + CT regimen for the low-to-intermediate-risk patients. Thus, ATO + ATRA and RIF + ATRA might be considered the optimum treatments for the newly diagnosed APL and should be recommended as the standard care for frontline therapy.

    INTRODUCTION: The incidence of new HIV diagnoses in Denmark has remained stable since 1991, but it has increased among the subgroup of homosexual men in recent years. This may reflect an actual increase in newly infected, e.g. as a result of increased risk behaviour, or it may reflect increased HIV....... MATERIALS AND METHODS: Observational study based on the Danish HIV Cohort Study, which includes all adults seen at Danish HIV clinics since 1995. RESULTS: From 2000 to 2004 the number of newly-infected homosexual men increased (from 69 to 123), particularly in persons under 30 years (from 5 to 42......). The median CD4 cell count at the time of diagnosis increased in this group (median 19.1 cells/microL per year [95% CI: 3.7-11.3]), while it remained stable among heterosexually infected. The number of newly-diagnosed homosexually infected under 30 years with a CD4 cell count over 400 cells/microL increased...

    2010-01-01

    In Japan, an ISO15189 accreditation system was started in 2005. To date, 47 hospitals have been accredited. In this session, I will present the merits of acquiring accreditation regarding ISO15189 based on our experience. Our hospital has 263 beds. The Clinical Examination Section consists of 12 staff (including 5 part-time workers): 7 in change of sample examination and 5 in charge of physiological examination. The annual number of samples is approximately 150,000. Samples collected on health checkups account for 90%. To improve the quality and service, assessment by third persons has been positively utilized in our hospital. Accreditation regarding ISO9001, ISO14001, ISO27001, privacy mark, hospital function assessment, the functional assessment of "ningen-dock"/health checkup hospitals, labor/hygiene service function assessment, and ISO15189 has been acquired. Patients may not recognize ISO. So, it must be utilized, considering that the acquisition of accreditation is not a goal but a starting point. Furthermore, cost-performance should be improved to achieve utilization-related merits. It is important to not only acquire accreditation but also help clinical staff and patients become aware of some changes/merits. Patients may consult a hospital for the following reasons: confidence in the hospital, and the staffs kind/polite attitudes. Long-term management strategies should be established without pursuing only short-term profits. I will introduce several merits of acquiring accreditation regarding ISO15189. Initially, incidental conditions for bids and appeal points include accreditation regarding ISO15189. Our corporation has participated in some competitive bids regarding health checkup business. In some companies, the bid conditions included ISO acquisition. In our hospital, clinical trials have been positively carried out. For participation in trials, hospitals must pass an institutional examination. However, ISO acquisition facilitates the preparation of

    AIM: Acquired hepatocerebral degeneration (AHD) is an exceptional type of hepatic encephalopathies (HE). It is characterized by neuropsychiatric and extrapyramidal symptomathology similar to that seen in hepatolenticular degeneration (Wilson's disease). In this paper, we report a case of AHD with unusual presenting features.METHODS: A 28-year-old man with AHD was described and the literature was reviewed.RESULTS: The man had a history of HBV-related liver cirrhosis. He was admitted to our hospital with apathy,dysarthria, mild consciousness impairment and extrapyramidal symptoms after hematemesis. By review of the literature,cases with AHD often did not present consciousness impairment. So our case was once diagnosed incorrectly as Wilson's disease.CONCLUSION: AHD is a rare syndrome and its variable clinical manifestations make it difficult to be diagnosed.But we believe that extensive examination and thorough understanding of the disease are beneficial to a correct diagnosis. Moreover, biocoene is effective in treating the case.

    Asano, Michiko; Yokosawa, Kazuhiko

    2012-06-01

    Determinants of synesthetic color choice for the Japanese logographic script, Kanji, were studied. The study investigated how synesthetic colors for Kanji characters, which are usually acquired later in life than other types of graphemes in Japanese language (phonetic characters called Hiragana and Katakana, and Arabic digits), are influenced by linguistic properties such as phonology, orthography, and meaning. Of central interest was a hypothesized generalization process from synesthetic colors for graphemes, learned prior to acquisition of Kanji, to Kanji characters learned later. Results revealed that color choices for Kanji characters depend on meaning and phonological information. Some results suggested that colors are generalized from Hiragana characters and Arabic digits to Kanji characters via phonology and meaning, respectively. Little influence of orthographic information was observed. The findings and approach of this study contributes to a clarification of the mechanism underlying grapheme-color synesthesia, especially in terms of its relationship to normal language processing.

  19. Acquiring Correct Knowledge for Natural Language Generation

    Reiter, E; Sripada, S G; 10.1613/jair.1176

    2011-01-01

    Natural language generation (NLG) systems are computer software systems that produce texts in English and other human languages, often from non-linguistic input data. NLG systems, like most AI systems, need substantial amounts of knowledge. However, our experience in two NLG projects suggests that it is difficult to acquire correct knowledge for NLG systems; indeed, every knowledge acquisition (KA) technique we tried had significant problems. In general terms, these problems were due to the complexity, novelty, and poorly understood nature of the tasks our systems attempted, and were worsened by the fact that people write so differently. This meant in particular that corpus-based KA approaches suffered because it was impossible to assemble a sizable corpus of high-quality consistent manually written texts in our domains; and structured expert-oriented KA techniques suffered because experts disagreed and because we could not get enough information about special and unusual cases to build robust systems. We bel...

    Cho, S Y; Maguire, R F

    1980-08-01

    Acquired cutis laxa is a rare disorder characterized by diffuse laxity of the skin and loss of connective tissue support with involvement of the lungs, gastrointestinal tract, pelvic organs, and aorta. The case report presented herein describes a forty-six year old woman with multiple myeloma and cutis laxa. Her history included several severe allergic reactions and the gradual development of lax skin, loss of connective tissue support throughout the body, and emphysema. At autopsy, multiple myeloma, diffuse laxity of the skin, and panacinar emphysema were found. The amount of elastic fiber in the skin, lungs, and aorta was decreased and showed abnormal fragmentation. Results of direct immunofluorescence study demonstrated IgG bound to dermal elastic fibers. Speculation regarding an immunologic etiology of the elastic tissue abnormality is presented herein.

  1. Time dysperception perspective for acquired brain injury

    Directory of Open Access Journals (Sweden)

    Federica ePiras

    2014-01-01

    Full Text Available Distortions of time perception are presented by a number of neuropsychiatric disorders. Here we survey timing abilities in clinical populations with acquired brain injuries in key cerebral areas recently implicated in human studies of timing. We purposely analyzed the complex relationship between cognitive and contextual factors involved in time estimation, as to characterize the correlation between timed and other cognitive behaviors in each group. We assume that interval timing is a solid construct to study cognitive dysfunctions following brain injury, as timing performance is a sensitive metric of information processing, while temporal cognition has the potential of influencing a wide range of cognitive processes. Moreover, temporal performance is a sensitive assay of damage to the underlying neural substrate after a brain insult. Further research in neurological and psychiatric patients will definitively answer the question of whether time distortions are manifestations of cognitive and behavioral symptoms of brain damage and definitively clarify their mechanisms.

    2012-01-01

    Summary Ion channel dysfunction or “channelopathy” is a proven cause of epilepsy in the relatively uncommon genetic epilepsies with Mendelian inheritance. But numerous examples of acquired channelopathy in experimental animal models of epilepsy following brain injury have also been demonstrated. Our understanding of channelopathy has grown due to advances in electrophysiology techniques that have allowed the study of ion channels in the dendrites of pyramidal neurons in cortex and hippocampus. The apical dendrites of pyramidal neurons comprise the vast majority of neuronal surface membrane area, and thus the majority of the neuronal ion channel population. Investigation of dendritic ion channels has demonstrated remarkable plasticity in ion channel localization and biophysical properties in epilepsy, many of which produce hyperexcitability and may contribute to the development and maintenance of the epileptic state. Here we review recent advances in dendritic physiology and cell biology, and their relevance to epilepsy. PMID:23216577

    Hypertrichosis is the excessive hair growth in any area of the skin surface. Acquired localized hypertrichosis may be secondary to multiple causes and there is a secondary form due to several drugs, which is usually reversible with discontinuation of the causative agent. Rivastigmine is a reversible and competitive inhibitor of acetylcholinesterase and butyrylcholinesterase used for symptomatic treatment of Alzheimer dementia and Parkinson's disease. It has an adequate safety profile and cutaneous side effects are unusual. Irritant contact dermatitis, allergic dermatitis, baboon syndrome, and cutaneous rash due to rivastigmine have been reported. We report on a Caucasian 80-year-old male with personal history of Alzheimer's disease. The patient started therapy with oral rivastigmine one month prior to clinical presentation of localized hypertrichosis on both forearms. Norgalanthamine has been shown to promote hair growth activity via the proliferation of dermal papilla. Acetylcholinesterase inhibitors can induce hair growth. PMID:27073702

    Dermal melanocytoses comprise a variety of congenital and acquired conditions characterized by a sparse population of intradermal dendritic, variably pigmented, spindle-shaped melanocytes. While Mongolian spot, Ota's and Ito's nevi are usually present at birth or appear around puberty; acquired dermal melanocytoses that appear in adult life are extremely rare. They include the facial lesions of acquired bilateral nevus of Ota-like macules, also named Hori's nevus, and the acquired unilateral nevus of Ota, also known as Sun's nevus. Uncommon extrafacial examples of acquired dermal melanocytoses include lesions involving upper extremities, wrist, back, lower extremities and dorsal aspects of the hands and feet. They are more prevalent among Asian women. In general, dermal melanocytoses are rare lesions in Caucasian patients and acquired variants are exceedingly uncommon. We report a rare example of acquired Ito's nevus that appeared in a Caucasian elderly woman and review the literature about acquired dermal melanocytoses.

    2014-01-30

    The interpersonal theory of suicidal behavior proposes that fearlessness of death and physical pain insensitivity is a necessary requisite for self-inflicted lethal self-harm. Repeated experiences with painful and provocative events are supposed to cause an incremental increase in acquired capability. The present study examined whether playing a first-person shooter-game in contrast to a first-person racing game increases pain tolerance, a dimension of the acquired capability construct, and risk-taking behavior, a risk factor for developing acquired capability. N=81 male participants were randomly assigned to either play an action-shooter or a racing game before engaging in a game on risk-taking behavior and performing a cold pressor task (CPT). Participants exhibited higher pain tolerance after playing an action shooter game than after playing a racing game. Furthermore, playing an action shooter was generally associated with heightened risk-taking behavior. Group-differences were not attributable to the effects of the different types of games on self-reported mood and arousal. Overall these results indicate that action-shooter gaming alters pain tolerance and risk-taking behavior. Therefore, it may well be that long-term consumption of violent video games increases a person's capability to enact lethal self-harm.

  10. Does Acquired Hypothyroidism Affect the Hearing Functions?

    Full Text Available Purpose: It is well known that congenital hypothyroidism can cause hearing loss. However, conflicting results were found in studies investigating hearing functions in acquired hypothyroidism. Therefore, we evaluated the audiometric findings in patients with acquired hypothyroidism. Material and Method: The study included 58 patients with hypothyroidism and age- and gender-matched 34 healthy controls. Twenty eight (48.27% patients had subclinical hypothyroidism, and 30 (51.73% had obvious hypothyroidism. All subjects had a normal otoscopic examination and tympanometry. Pure tone audiometry at 250, 500, 1000, 2000, 4000, 6000, and 8000 Hertz (Hz was performed in both groups. Blood pressure measurements and the levels of plasma electrolytes, lipids and vitamin B12 were available in all subjects. Results: Hypothyroidism group and control group were similar with respect to systolic and diastolic blood pressures and plasma glucose, lipid, vitamin B12, calcium, sodium, potassium, and chloride levels. Significantly higher audiometric thresholds (dB at 250 (10 (0-45 vs. 5 (0-15, p<0.001 and 500 Hz (10 (0-40 vs. 10 (-5-15, p=0.003 were recorded in hypothyroid patients compared to that in healthy controls. Hearing thresholds at 250 and 500 Hz correlated positively with thyroid-stimulating hormone (TSH, and negatively with free triiodothyronine and free thyroxine. Subclinical hypothyroid patients had a higher hearing threshold at 250 Hz than healthy controls (p=0.001. Discussion: Our study demonstrated that hearing ability decreases in hypothyroidism, even in subclinical hypothyroidism. The changes in TSH and thyroid hormone levels seem to be directly related to the hearing loss in this population of patients.

    Full Text Available In this study, it has been purposed to share practice of event-scene administration, search and rescue and evacuation of injured and acquired experiences carried out throughout a building collapse. After an explosion at Diyarbakir Kurdoglu housings at 11 December 2006 about 08:20AM, five flats of an apartment that has five floors-ten flats were collapsed. Local military hospital ambulances, city ambulances, and fire-fighting vehicles arrived to event-place 10 minutes later. It has been found out that there were 13 people inside, 6 of which were children. Army rescue team arrived event-place about 01:30PM, then all non-professional persons has been sent away from region. Eight dead including five children, and five injured including one child have been taken out. Two people from close area have been also injured mildly due to the explosion. It has been found out that accident caused by boiler tank exploding. Sixth of total eight injured had only superficial wounds. Other two injured have been followed because of head trauma at first one and hepatic contusion and rib fracture at the other one. No complication observed after follow-up. Building collapses can create disaster potential according to the number of people inside and facilities of nearby region of the place accident taken place. The evaluation of the direction of building collapse during search and rescue operation would enhance possibility to reach more living in shorter time. Building collapses which can be considered as a miniature of big disaster potentials like earthquakes can be appraised as an important practical training and experience source on event-place administration, search and rescue operations and injured evacuation. We believe that share of the analysis and acquired experiences of this kind of studies would contribute interfering big disaster potentials. [TAF Prev Med Bull 2012; 11(2.000: 241-244

    Aim The aim of this research was to explore how newly qualified nurses learn to organise, delegate and supervise care in hospital wards when working with and supervising healthcare assistants. It was part of a wider UK research project to explore how newly qualified nurses recontextualise the knowledge they have gained during their pre-registration nurse education programmes for use in clinical practice. Method Ethnographic case studies were conducted in three hospital sites in England. Data collection methods included participant observations and semi-structured interviews with newly qualified nurses, healthcare assistants and ward managers. A thematic analysis was used to examine the data collected. Findings Five styles of how newly qualified nurses delegated care to healthcare assistants were identified: the do-it-all nurse, who completes most of the work themselves; the justifier, who over-explains the reasons for decisions and is sometimes defensive; the buddy, who wants to be everybody's friend and avoids assuming authority; the role model, who hopes that others will copy their best practice but has no way of ensuring how; and the inspector, who is acutely aware of their accountability and constantly checks the work of others. Conclusion Newly qualified nurses require educational and organisational support to develop safe and effective delegation skills, because suboptimal or no delegation can have negative effects on patient safety and care.

    We examined the relationship between the O(6)-methylguanine-methyltransferase (MGMT) methylation status and clinical outcomes in newly diagnosed glioblastoma multiforme (GBM) patients who were treated with Gliadel wafers (Eisai, Tokyo, Japan). MGMT promoter methylation has been associated with increased survival among patients with GBM who are treated with various alkylating agents. MGMT promoter methylation, in DNA from 122 of 160 newly diagnosed GBM patients treated with Gliadel, was determined by a quantitative methylation-specific polymerase chain reaction, and was correlated with overall survival (OS) and recurrence-free survival (RFS). The MGMT promoter was methylated in 40 (32.7%) of 122 patients. The median OS was 13.5 months (95% confidence interval [CI] 11.0-14.5) and RFS was 9.4 months (95% CI 7.8-10.2). After adjusting for age, Karnofsky performance score, extent of resection, temozolomide (TMZ) and radiation therapy (RT), the newly diagnosed GBM patients with MGMT methylation had a 15% reduced mortality risk, compared to patients with unmethylated MGMT (hazard ratio 0.85; 95% CI 0.56-1.31; p=0.46). The patients aged over 70 years with MGMT methylation had a significantly longer median OS of 13.5 months, compared to 7.6 months in patients with unmethylated MGMT (p=0.027). A significant difference was also found in older patients, with a median RFS of 13.1 versus 7.6 months for methylated and unmethylated MGMT groups, respectively (p=0.01). Methylation of the MGMT promoter in newly diagnosed GBM patients treated with Gliadel, RT and TMZ, was associated with significantly improved OS compared to the unmethylated population. In elderly patients, methylation of the MGMT promoter was associated with significantly better OS and RFS.

    Full Text Available Clinical decision support systems that notify providers of abnormal test results have produced mixed results. We sought to develop, implement, and evaluate the impact of a computer-based clinical alert system intended to improve atrial fibrillation stroke prophylaxis, and identify reasons providers do not implement a guideline-concordant response.We conducted a cohort study with historical controls among patients at a tertiary care hospital. We developed a decision rule to identify newly-diagnosed atrial fibrillation, automatically notify providers, and direct them to online evidence-based management guidelines. We tracked all notifications from December 2009 to February 2010 (notification period and applied the same decision rule to all patients from December 2008 to February 2009 (control period. Primary outcomes were accuracy of notification (confirmed through chart review and prescription of warfarin within 30 days.During the notification period 604 notifications were triggered, of which 268 (44% were confirmed as newly-diagnosed atrial fibrillation. The notifications not confirmed as newly-diagnosed involved patients with no recent electrocardiogram at our institution. Thirty-four of 125 high-risk patients (27% received warfarin in the notification period, compared with 34 of 94 (36% in the control period (odds ratio, 0.66 [95% CI, 0.37-1.17]; p = 0.16. Common reasons to not prescribe warfarin (identified from chart review of 151 patients included upcoming surgical procedure, choice to use aspirin, and discrepancy between clinical notes and the medication record.An automated system to identify newly-diagnosed atrial fibrillation, notify providers, and encourage access to management guidelines did not change provider behaviors.

    Oral glucose-lowering medications are associated with excess risk of heart failure (HF). Given the absence of comparative data among drug classes, we performed a retrospective study in 32 Health Services of 16 Italian regions accounting for a population of 18 million individuals, to assess the association between HF risk and use of sulphonylureas, DPP-4i, and glitazones. We extracted data on patients with type 2 diabetes who initiated treatment with DPP-4i, thiazolidinediones, or sulphonylureas alone or in combination with metformin during an accrual time of 2 years. The endpoint was hospitalization for HF (HHF) occurring after the first 6 months of therapy, and the observation was extended for up to 4 years. A total of 127 555 patients were included, of whom 14.3% were on DPP-4i, 72.5% on sulphonylurea, 13.2% on thiazolidinediones, with average 70.7% being on metformin as combination therapy. Patients in the three groups differed significantly for baseline characteristics: age, sex, Charlson index, concurrent medications, and previous cardiovascular events. During an average 2.6-year follow-up, after adjusting for measured confounders, use of DPP-4i was associated with a reduced risk of HHF compared with sulphonylureas [hazard ratio (HR) 0.78; 95% confidence interval (CI) 0.62-0.97; P = 0.026]. After propensity matching, the analysis was restricted to 39 465 patients, and the use of DPP-4i was still associated with a lower risk of HHF (HR 0.70; 95% CI 0.52-0.94; P = 0.018). In a very large observational study, the use of DPP-4i was associated with a reduced risk of HHF when compared with sulphonylureas. Published on behalf of the European Society of Cardiology.

    Periodontal regenerative techniques have been proposed; however, the outcomes remain debatable. The present investigation assessed the regenerated cementum following enamel matrix derivative application in dehiscence-type defects. Buccal osseous dehiscences were surgically created on the maxillary cuspid, and the second and fourth premolars in five female beagle dogs. The treatment group (n = 15 sites) received the enamel matrix derived application, whereas the control groups (n = 15) did not. The dogs were sacrificed 4 months following treatment and the specimens were histologically and histometrically examined. The newly formed cementum was uneven in thickness and mineralization, overlapped the old cementum and exhibited functional orientation, cementocyte lacunae and collagen fibril bundles. Most of the histological specimens showed the presence of a gap between the newly formed cementum and the underlying dentin. Control sites did not exhibit any cementum formation. The present study concluded that newly formed cementum is of cellular type and exhibits multiple characteristics.

    Acquired epilepsy is frequently associated with structural lesions after trauma, stroke, and infections. Although seizures are often difficult to treat, there is no clinically applicable strategy to prevent the development of epilepsy in patients at risk. We have recently shown that vascular injury is associated with activation of albumin-mediated transforming growth factor β (TGF-β) signaling, and followed by local inflammatory response and epileptiform activity ex vivo. Here we investigated albumin-mediated TGF-β signaling and tested the efficacy of blocking the TGF-β pathway in preventing epilepsy. We addressed the role of TGF-β signaling in epileptogenesis in 2 different rat models of vascular injury, combining in vitro and in vivo biochemical assays, gene expression, and magnetic resonance and direct optical imaging for blood-brain barrier permeability and vascular reactivity. Long-term electrocorticographic recordings were acquired in freely behaving animals. We demonstrate that serum-derived albumin preferentially induces activation of the activin receptor-like kinase 5 pathway of TGF-β receptor I in astrocytes. We further show that the angiotensin II type 1 receptor antagonist, losartan, previously identified as a blocker of peripheral TGF-β signaling, effectively blocks albumin-induced TGF-β activation in the brain. Most importantly, losartan prevents the development of delayed recurrent spontaneous seizures, an effect that persists weeks after drug withdrawal. TGF-β signaling, activated in astrocytes by serum-derived albumin, is involved in epileptogenesis. We propose losartan, a drug approved by the US Food and Drug Administration, as an efficient antiepileptogenic therapy for epilepsy associated with vascular injury. © 2014 American Neurological Association.

    Full Text Available Hospital-acquired pneumonia (HAP is a frequent cause of nosocomial infections, responsible for great morbidity and mortality worldwide. The majority of studies on HAP have been conducted in patients hospitalized in the intensive care unit (ICU, as mechanical ventilation represents a major risk factor for nosocomial pneumonia and specifically for ventilator-associated pneumonia. However, epidemiological data seem to be different between patients acquiring HAP in the ICU vs. general wards, suggesting the importance of identifying non ICU-acquired pneumonia (NIAP as a clinical distinct entity in terms of both etiology and management. Early detection of NIAP, along with an individualized management, is needed to reduce antibiotic use and side effects, bacterial resistance and mortality. The present article reviews the pathophysiology, diagnosis, treatment and prevention of NIAP.

    Full Text Available Background: Prevalence of diabetes is on an increase in India, currently there is limited nation-wide data regarding the prevalence of chronic complications in diabetic patients at diagnosis. This information will help health-care professionals approach management more aggressively to prevent complications. Objective: To determine the prevalence of chronic complications in newly-diagnosed Type 2 diabetic (T2D patients in India. Design and Methods: This was a cross-sectional survey of T2D patients, diagnosed within 3 months of their first visit to the centers doing the survey. Each patient was screened for diabetic complications, hypertension, dyslipidemia, and body mass index. Family history was recorded. Standard protocols were used to make the diagnosis of retinopathy, neuropathy and nephropathy. Data analysis was carried out using the standard statistical techniques. Results: Of the total 4,600 (males 67%, females 33% newly diagnosed patients with T2D, majority were from the age group 41-50 years (40%. 13.15% of newly detected India T2D had neuropathy 6.1% had retinopathy and 1.06% had nephropathy. Risk factors of macro vascular complication such as hypertension, obesity, and dyslipidemia were observed in 23.3%, 26%, and 27% of patients respectively. Ischemic heart disease was noticed in 6%. Conclusion: High prevalence of micro vascular complications was present at diagnosis along with association of CV cardiovascular risk factors among Indian T2D. In view of this, screening must be instituted for all diabetics for complications at the time of diagnosis itself.

    Bullous diseases of the oral cavity cause painful erosion. They must be distinguished from aphthae and vesicles which may have a similar presentation. Acute, chronic and congenital conditions are recognized. Acute lesions may involve a polymorphous oral erhythema which has an polymorphous erythematous presentation or toxidermia (Stevens-Johnson syndrome, Lyell syndrome, fixed pigmented erythema). Examination of the skin and history taking are the keys to diagnosis. Patients with chronic bullous diseases may have a congenital condition (bullous epidermolysis or lymphangioma) suggested by the age at onset and the clinical presentation. Acquired chronic bullous diseases include lichen planus and autoimmune bullous diseases. Careful examination is essential to identify mucosal or cutaneous involvement and to obtain a biopsy for histological examination. Search for antibodies deposited in the perilesional mucosa is necessary. Chronic erosive gingivitis is a frequent presentation. Most of the patients have cicatricial pemphigoid, lichen planus, and more rarely pemphigus. The pinch sign is highly discriminative to differentiate the cause of this syndrome. Symptomatic treatment of bullous lesions of the oral cavity include adapted diet and correct and early use of antalgesics.

    Full Text Available Background: The course of human immunodeficiency virus infection and the acquired immunodeficiency syndrome can be complicated by a variety of endocrine abnormalities, including abnormalities of thyroid gland. Materials and Methods: This study was designed to understand the spectrum of pathology of thyroid in Indian patients with AIDS. The present study describes the findings of retrospective autopsy findings of 158 patients with AIDS which revealed infectious diseases from a time period before the use of highly active antiretroviral regimen. Results: A wide range of bacterial, fungal, and viral infections were observed. Tuberculosis was recorded in 14 (09% patients, Cryptococcus neoformans in 11 (7% patients and cytomegalovirus in 3 (2% patients. Hashimoto's thyroiditis and lymphocytic thyroiditis were seen in 02 (01% patients each. One patient had dual infection comprising of tuberculosis and cytomegalovirus infection. The other microscopic findings observed were goiter (2 patients, interstitial fibrosis in thyroid (7 patients, and calcification in thyroid (8 patients. Conclusions: Abnormalities of thyroid are uncommon findings in patients with HIV infection however several case reports of thyroid involvement by infectious agents and neoplasm are described in these patients; hence patients with HIV infection should be closely followed up for development of goiter or abnormalities of thyroid functions.

    The neocortex is the site of origin of several forms of acquired epilepsy. Here we provide a brief review of experimental models that were recently developed to study neocortical epileptogenesis as well as some major results obtained with these methods. Most of neocortical seizures appear to be nocturnal and it is known that neuronal activities reveal high levels of synchrony during slow-wave sleep. Therefore, we start the review with a description of mechanisms of neuronal synchronization and major forms of synchronized normal and pathological activities. Then, we describe three experimental models of seizures and epileptogenesis: ketamine-xylazine anesthesia as feline seizure triggered factor, cortical undercut as cortical penetrating wound model and neocortical kindling. Besides specific technical details describing these models we also provide major features of pathological brain activities recorded during epileptogenesis and seizures. The most common feature of all models of neocortical epileptogenesis is the increased duration of network silent states that up-regulates neuronal excitability and eventually leads to epilepsy.

    Davies-Thompson, Jodie; Pancaroglu, Raika; Barton, Jason

    2014-01-01

    Cognitive models propose a hierarchy of parallel processing stages in face perception, and functional neuroimaging shows a network of regions involved in face processing. Reflecting this, acquired prosopagnosia is not a single entity but a family of disorders with different anatomic lesions and different functional deficits. One classic distinction is between an apperceptive variant, in which there is impaired perception of facial structure, and an associative/amnestic variant, in which perception is relatively intact, with subsequent problems matching perception to facial memories, because of either disconnection or loss of those memories. These disorders also have to be distinguished from people-specific amnesia, a multimodal impairment, and prosop-anomia, in which familiarity with faces is preserved but access to names is disrupted. These different disorders can be conceived as specific deficits at different processing stages in cognitive models, and suggests that these functional stages may have distinct neuroanatomic substrates. It remains to be seen whether a similar anatomic and functional variability is present in developmental prosopagnosia.

  11. Acquired Hemophilia A successfully treated with rituximab

    2015-02-01

    Full Text Available Acquired hemophilia A (AHA is a rare bleeding disorder due to the development of specific autoantibodies against factor VIII. The anti-CD20 monoclonal antibody Rituximab has been proven to be effective in  obtaining a long-term suppression of inhibitors of AHA,  besides other immunosuppressive standard treatments. Here we describe a case of idiopathic AHA in a 60-year old man successfully treated with rituximab. He showed a complete clinical response with  a normalization of clotting  parameters after 5 weekly courses of rituximab given at a dose of 375 mg/sqm. , but after stopping rituximab, an initial worsening of coagulation  parameters  induced the addition of 3 further courses. At present, the patient is in complete clinical and hematological remission after 200 days.  This case confirms that Rituximab may be a safe and useful tool to treat AHA and, a prolonged administration can overcome the initial resistance. However, the precise position of this drug in the therapeutic strategy (first or second-line, alone or in combination with other drugs remains to be established and warrants further investigation.

    Acquired immune deficiency syndrome (AIDS) is an immune deficiency disease. The etiology of hyperthyroidism, which can also be immune-related, is usually divided into six classical categories, including hypophyseal, hypothalamic, thyroid, neoplastic, autoimmune and inflammatory hyperthyroidism. Hyperthyroidism is a rare complication of highly active antimicrobial therapy (HAART) for human immunodeficiency virus (HIV). Hyperthyroidism caused directly by AIDS has not been previously reported. A 29-year-old man who complained of dyspnea and asthenia for 1 month, recurrent fever for more than 20 days, and breathlessness for 1 week was admitted to our hospital. The thyroid function test showed that the level of free thyroxine (FT4) was higher than normal and that the level of thyroid-stimulating hormone (TSH) was below normal. He was diagnosed with hyperthyroidism. Additional investigations revealed a low serum albumin level and chest infection, along with diffuse lung fibrosis. Within 1 month, he experienced significant weight loss, no hand tremors, intolerance of heat, and perspiration proneness. We recommended an HIV examination; subsequently, AIDS was diagnosed based on the laboratory parameters. This is the first reported case of hyperthyroidism caused by AIDS. AIDS may cause hyperthyroidism by immunization regulation with complex, atypical, and easily ignored symptoms. Although hyperthyroidism is rare in patients with AIDS, clinicians should be aware of this potential interaction and should carefully monitor thyroid function in HIV-positive patients.

    This study determined the colonisation scenario of Listeria monocytogenes in a newly-opened ready-to-eat meat processing facility using a combination of classical microbiology and molecular biology techniques. Samples (n=183), including food contact surfaces, non-food contact surfaces, raw materials and food samples, collected on four sampling occasions, were analysed for L. monocytogenes by the ISO 11290:1996 standard method and by real-time PCR applied to the second enrichment broth from the ISO method. No L. monocytogenes were detected on the first sampling occasion, but by the second sampling occasion a persistent clone had colonised the facility. Analysis of the second enrichment of the ISO method by real-time PCR was more sensitive for the detection of L. monocytogenes than the ISO method alone. In order to reduce the risk of cross contamination and the public health risk, awareness and proactive measures are required to control L. monocytogenes from the first days of production in a newly opened meat processing facility.

    2013-01-01

    Full Text Available Introduction and Aim. Type-1-diabetes mellitus (T1DM is the most commonly diagnosed type of DM in children and adolescents. We aim to identify the epidemiological profile, risk factors, clinical features, and factors related to delayed diagnosis or mismanagement in children with newly diagnosed T1DM in Taif, Saudi Arabia. Patients and Methods. Ninety-nine newly diagnosed patients were included in the study along with 110 healthy controls. Patients were classified into 3 groups (I: >2 years, II: 2–>6 years, and III: 6–12 years. Both patients and controls were tested for C-peptide, TSH, and autoantibodies associated with DM and those attacking the thyroid gland. Results. Diabetic ketoacidosis was present in 79.8%. Delayed and missed diagnoses were recorded in 45.5%, with significant correlation to age and district of origin. Severity at presentation showed significant correlation with age and cow’s milk feeding. Group I, those with misdiagnosis or positive DM related autoantibodies, had more severe presentations. The correlation of C-peptide and TSH levels in patients and controls was significant for C-peptide and nonsignificant for TSH. Conclusion. Misdiagnosis and mismanagement are common and account for more severe presentation, especially in young children >2 years. Early introduction of cow’s milk appears to be a risk factor for the development of T1DM.

    Pavli, Androula; Maltezou, Helena

    2017-07-01

    The number of migrants and refugees in Europe in the past few years has increased dramatically due to war, violence or prosecutions in their homeland. Migration may affect physical, mental and social health. The objective of this article is to assess migrants and refugees' health problems, and to recommend appropriate interventions. A PubMed search of published articles on health problems of newly arrived migrants and refugees was conducted from 2003 through 2016, focusing on the current refugee crisis in Europe. In addition to communicable diseases, such as respiratory, gastrointestinal and dermatologic infections, non-communicable diseases, including chronic conditions, mental and social problems, account for a significant morbidity burden in newly arrived migrants and refugees. Vaccine-preventable diseases are also of outmost importance. The appropriate management of newly arrived refugees and migrants' health problems is affected by barriers to access to health care including legal, communication, cultural and bureaucratic difficulties. There is diversity and lack of integration regarding health care provision across Europe due to policy differences between health care systems and social services. There is a notable burden of communicable and non-communicable diseases among newly arrived migrants and refugees. Provision of health care at reception and temporary centres should be integrated and provided by a multidisciplinary team Appropriate health care of migrants and refugees could greatly enhance their health and social status which will benefit also the host countries at large.

  8. Being a team leader: newly registered nurses relate their experiences.

    Ekström, Louise; Idvall, Ewa

    2015-01-01

    This paper presents a study that explores how newly qualified registered nurses experience their leadership role in the ward-based nursing care team. A nurse's clinical leadership affects the quality of care provided. Newly qualified nurses experience difficulties during the transition period from student to qualified professional and find it challenging to lead nursing care. Twelve nurses were interviewed and the transcribed texts analysed using qualitative content analysis to assess both manifest and latent content. Five themes were identified: feeling stranded; forming well-functioning teams; learning to lead; having the courage, strength, and desire to lead; and ensuring appropriate care. The findings indicate that many factors limit nurses' leadership but some circumstances are supportive. The leadership prerequisites for newly registered nurses need to improve, emphasizing different ways to create a supportive atmosphere that promotes professional development and job satisfaction. To increase nurse retention and promote quality of care, nurse managers need to clarify expectations and guide and support newly qualified nurses in a planned way. © 2013 John Wiley & Sons Ltd.

    The HI Parkes All-Sky Survey (HIPASS) is a blind 21-cm survey for extragalactic neutral hydrogen, covering the whole southern sky. The HIPASS Bright Galaxy Catalog (BGC; Koribalski et al. 2002) is a subset of HIPASS and contains the 1000 HI-brightest (peak flux density) galaxies. Here we present the 138 HIPASS BGC galaxies, which had no redshift measured prior to the Parkes multibeam HI surveys. Of the 138 galaxies, 87 are newly cataloged. Newly cataloged is defined as no optical (or infrared) counterpart in the NASA/IPAC Extragalactic Database. Using the Digitized Sky Survey we identify optical counterparts for almost half of the newly cataloged galaxies, which are typically of irregular or magellanic morphological type. Several HI sources appear to be associated with compact groups or pairs of galaxies rather than an individual galaxy. The majority (57) of the newly cataloged galaxies lie within ten degrees of the Galactic Plane and are missing from optical surveys due to confusion with stars or dust extinc...

    Moon, K.L. Jr.; Federle, M.P.; Abrams, D.I.; Volberding, P.; Lewis, B.J.

    1984-02-01

    Abdominal computed tomography (CT) was performed in 31 patients with Kaposi sarcoma (KS) related to acquired immunodeficiency syndrome (AIDS), three patients with classic KS, and 12 patients with the newly described lymphadenopathy syndrome (LNS). The frequency, distribution, and appearance of lymphadenopathy and splenomegaly were similar in the AIDS-related KS and LNS groups. Rectal and perirectal disease was identified in 86% of homosexual men studied; rectal KS could not be distinguished from proctitis on CT criteria alone. No CT abnormalities were seen in patients with classic KS. The CT demonstration of retroperitoneal, mesenteric, or pelvic adenopathy or of rectal or perirectal disease in patients with AIDS-related KS is not necessarily indicative of widespread involvement with the disease.

  20. Chapter 22: Hereditary and acquired angioedema.

    Science.gov (United States)

    Georgy, Mary S; Pongracic, Jacqueline A

    2012-01-01

    Hereditary angioedema (HAE) is an autosomal dominant disorder defined by a deficiency of functional C1 esterase inhibitor (C1-INH). Acquired angioedema (AAE) is caused by either consumption (type 1) or inactivation (type 2) of CI-INH. Both HAE and AAE can be life-threatening. The screening test for both conditions is complement component C4, which is low to absent at times of angioedema or during quiescent periods. A useful test to differentiate HAE from AAE is C1q protein, which is normal in HAE and low in AAE. There are three types of HAE: type 1 HAE is most common, occurring in ∼85% of patients and characterized by decreased production of C1-INH, resulting in reduced functional activity to 5-30% of normal. In type 2, which occurs in 15% of cases, C1-INH is detectable in normal or elevated quantities but is dysfunctional. Finally, type 3, which is rare and almost exclusively occurs in women, is estrogen dependent and associated with normal CI-INH and C4 levels. One-third of these patients have a gain-of-function mutation in clotting factor XII leading to kallikrein-driven bradykinin production. Although the anabolic steroid, danazol, is useful in increasing the concentration of C4 and reducing the episodes of angioedema in HAE and AAE, it has expected adverse effects. Fortunately, disease-specific therapies are available and include C1-INH enzyme for i.v. infusion either acutely or empirically, ecallantide, an inhibitor of kallikrein, and icatibant, a bradykinin B2-receptor antagonist, both approved for acute angioedema and administered, subcutaneously.
