Attention bias modification add-on to inpatient treatment for young women with anorexia nervosa-A randomized controlled trial.

Patients with anorexia nervosa (AN) display elevated anxiety and attention biases (ABs) in threat processing. Attention bias modification treatment (ABMT) is considered promising for anxiety disorders, but its potential for AN is limited. In this study, 154 young women hospitalised because of AN were assigned to ED-related and anxiety-related threat stimuli, or to a non-ABMT intervention control condition in a randomized control trial. Hundred-and-ten patients completed the study. ABMT was an add-on to the regular inpatient treatment. Research participants completed two pretreatment training sessions and eight biweekly sessions of ABMT. AB, ED-related symptoms, depression, anxiety and stress were assessed before and after ABMT in the research groups, and, similarly, 5 weeks apart, in the controls. We found that despite the different patterns of change in AB between the three groups following ABMT, the reduction in AB, or the between-group differences in AB-reduction, were not significant. While the severity of ED-symptoms, depression, anxiety and stress was reduced following ABMT, or control condition, in all groups, there were no between-group differences in these changes. Changes in AB were not correlated with baseline and pre-post-treatment changes in ED-related and comorbid symptomatology. Methodological and inpatient treatment-related considerations may explain our negative ABMT-related results.

Immature platelets in patients with Covid-19: association with disease severity.

Coronavirus disease 2019 (Covid-19) is associated with a high incidence of venous and arterial thromboembolic events. Currently, there are no clinical or laboratory markers that predict thrombotic risk. Circulating immature platelets are hyper-reactive platelets, which are associated with arterial thrombotic events. The aim of this study was to assess whether the proportion of circulating immature platelets is associated with disease severity in Covid-19 patients. Patients admitted with Covid-19 disease were prospectively assessed. Immature platelet count (IPC) and immature platelet fraction (IPF) were measured at admission and at additional time points during the hospital course using the Sysmex XN-3000 auto-analyzer. A total of 136 consecutive patients with Covid-19 were recruited [mean age 60 ± 19 years, 49% woman, 56 (41%) had mild-moderate disease and 80 (59%) had severe disease at presentation]. The median IPF% was higher in patients with severe compared to mild-moderate disease [5.8 (3.9-8.7) vs. 4.2 (2.73-6.45), respectively, p = 0.01]. The maximal IPC value was also higher in patients with severe disease [15 (10.03-21.56), vs 10.9 (IQR 6.79-15.62), respectively, p = 0.001]. Increased IPC was associated with increased length of hospital stay. Patients with severe Covid-19 have higher levels of IPF than patients with mild-moderate disease. IPF may serve as a prognostic marker for disease severity in Covid-19 patients.

Immature platelets in patients hospitalized with Covid-19.

Coronavirus disease 2019 (Covid-19) is associated with high incidence of venous and arterial thromboembolic events. Currently, there are no markers to guide antithrombotic therapy in Covid-19. Immature platelets represent a population of hyper-reactive platelets associated with arterial events. This prospective study compared consecutive Covid-19 patients (n = 47, median age = 56 years) to patients with acute myocardial infarction (AMI, n = 100, median age = 59 years) and a group of stable patients with cardiovascular risk factors (n = 64, median age = 68 years). Immature platelet fraction (IPF) and immature platelet count (IPC) were determined by the Sysmex XN-3000 auto-analyzer on admission and at subsequent time-points. IPF% on admission was higher in Covid-19 than the stable group and similar to the AMI group (4.8% [IQR 3.4-6.9], 3.5% [2.7-5.1], 4.55% [3.0-6.75], respectively, p = 0.0053). IPC on admission was also higher in Covid-19 than the stable group and similar to the AMI group (10.8 × 109/L [8.3-18.1], 7.35 × 109/L [5.3-10.5], 10.7 × 109/L [7.7-16.8], respectively, P < 0.0001). The maximal IPF% among the Covid-19 group was higher than the stable group and similar to the AMI group. The maximal IPC in Covid-19 was higher than the maximal IPC in both the stable and AMI groups (COVID-19: 14.4 × 109/L [9.4-20.9], AMI: 10.9 × 109/L [7.6-15.2], P = 0.0035, Stable: 7.55 × 109/L [5.55-10.5], P < 0.0001). Patients with Covid-19 have increased immature platelets indices compared to stable patients with cardiovascular risk factors, and as the disease progresses also compared to AMI patients. The enhanced platelet turnover and reactivity may have a role in the development of thrombotic events in Covid-19 patients.

Placenta-Derived Cell Therapy to Treat Patients With Respiratory Failure Due to Coronavirus Disease 2019.

OBJECTIVES: To determine whether placental cell therapy PLacental eXpanded (PLX)-PAD (Pluristem Therapeutics, Haifa, Israel) may be beneficial to treating critically ill patients suffering from acute respiratory distress syndrome due to coronavirus disease 2019. DESIGN: Retrospective case report of critically ill coronavirus disease 2019 patients treated with PLacental eXpanded (PLX)-PAD from March 26, 2020, to April 4, 2020, with follow-up through May 2, 2020. SETTING: Four hospitals in Israel (Rambam Health Care Campus, Bnai Zion Medical Center, and Samson Assuta Ashdod University Hospital), and Holy Name Medical Center in New Jersey. PATIENTS: Eight critically ill patients on invasive mechanical ventilation, suffering from acute respiratory distress syndrome due to coronavirus disease 2019. INTERVENTIONS: Intramuscular injection of PLacental eXpanded (PLX)-PAD (300 × 106 cells) given as one to two treatments. MEASUREMENTS AND MAIN RESULTS: Mortality, time to discharge, and changes in blood and respiratory variables were monitored during hospitalization to day 17 posttreatment. Of the eight patients treated (median age 55 yr, seven males and one female), five were discharged, two remained hospitalized, and one died. By day 3 postinjection, mean C-reactive protein fell 45% (240.3-131.3 mg/L; p = 0.0019) and fell to 77% by day 5 (56.0 mg/L; p < 0.0001). Pao2/Fio2 improved in 5:8 patients after 24-hour posttreatment, with similar effects 48-hour posttreatment. A decrease in positive end-expiratory pressure and increase in pH were statistically significant between days 0 and 14 (p = 0.0032 and p = 0.00072, respectively). A decrease in hemoglobin was statistically significant for days 0-5 and 0-14 (p = 0.015 and p = 0.0028, respectively), whereas for creatinine, it was statistically significant between days 0 and 14 (p = 0.032). CONCLUSIONS: Improvement in several variables such as C-reactive protein, positive end-expiratory pressure, and Pao2/Fio2 was observed following PLacental eXpanded (PLX)-PAD treatment, suggesting possible therapeutic effect. However, interpretation of the data is limited due to the small sample size, use of concomitant investigational therapies, and the uncontrolled study design. The efficacy of PLacental eXpanded (PLX)-PAD in coronavirus disease 2019 should be further evaluated in a controlled clinical trial.

High prevalence of attention-deficit/hyperactivity disorder in adolescents with severe obesity seeking bariatric surgery.

AIM: To examine the prevalence of attention-deficit/hyperactivity disorder (ADHD) and related post-surgical weight loss in adolescents with severe obesity seeking bariatric surgery. METHODS: The study population included 84 adolescents (age 13-19 years; 44 males, 40 females) with severe obesity who sought bariatric surgery at the Sheba Medical Centre in Israel during the years 2011-2017. Anthropometric and clinical data were collected from medical records. A subgroup of 20 participants filled questionnaires that evaluated ADHD-like symptoms, eating behaviours and quality of life. Data on adolescents that ultimately underwent surgery (n = 45) were also obtained. RESULTS: The prevalence of ADHD was 28.6% in adolescents seeking bariatric surgery, much higher than that of the general adolescent population of Israel (17.1%, P < .001). There were no significant differences in reductions of weight, body mass index, body mass index standard deviation scores and body fat percent between participants with or without ADHD. In the subgroup that filled questionnaires, higher scores on ADHD-Rating Scale at baseline were associated with greater excess weight loss. CONCLUSION: The prevalence of ADHD in adolescents seeking bariatric surgery was very high. Diagnosed ADHD was not related to post-surgical weight loss, whereas baseline ADHD-related behaviour was associated with higher post-surgical weight loss.

Obsessive-compulsive symptomatology in female adolescent inpatients with restrictive compared with binge-purge eating disorders.

OBJECTIVE: Strong relationships exist between obsessive-compulsive (OC) disorder and eating disorders (EDs). The aim of the study was to investigate whether OC symptoms would be expressed differently in different ED types. METHOD: Ninety-four female adolescent inpatients with restricting anorexia nervosa (AN-R), 67 with binge/purge AN (AN-B/P), and 48 with bulimia nervosa (BN) were assessed on admission and discharge using the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Yale-Brown-Cornell Eating Disorders Scale (YBC-EDS), Eating Attitude Test-26 (EAT-26), Beck Depression Inventory (BDI), and State-Trait Anxiety Inventory (STAI). RESULTS: On admission, patients with AN-B/P exhibited higher scores on the Y-BOCS, YBC-EDS, EAT-26, and BDI in comparison with patients with AN-R or BN. A significant improvement on all psychometric variables from admission to discharge was found for all participants taken together. Nonetheless, patients with AN-B/P and/or BN showed a greater improvement on Y-BOCS, BDI, and STAI than patients with AN-R, whereas no between-group difference was found for YBC-EDS and EAT-26. CONCLUSIONS: Obsessionality is more severe in acutely ill AN-B/P patients than in patients with AN-R and BN, whereas a greater improvement in obsessionality from the acutely ill to the stabilized ED condition is found in patients with binge/purge in comparison with restrictive pathology.

Different attention bias patterns in anorexia nervosa restricting and binge/purge types.

Patients with anorexia nervosa (AN) have been shown to display both elevated anxiety and attentional biases in threat processing. In this study, we compared threat-related attention patterns of patients with AN restricting type (AN-R; n = 32), AN binge/purge type (AN-B/P; n = 23), and healthy controls (n = 19). A dot-probe task with either eating disorder-related or general and social anxiety-related words was used to measure attention patterns. Severity of eating disorder symptoms, depression, anxiety, and stress were also assessed. Patients with AN-R showed vigilance to both types of threat words, whereas patients with AN-B/P showed avoidance of both threat types. Healthy control participants did not show any attention bias. Attention bias was not associated with any of the demographic, clinical, and psychometric parameters introduced. These findings suggest that there are differential patterns of attention allocation in patients with AN-R and AN-B/P. More research is needed to identify what causes/underlies these differential patterns.

Building and Validating a Computerized Algorithm for Surveillance of Ventilator-Associated Events.

OBJECTIVE: To develop an automated method for ventilator-associated condition (VAC) surveillance and to compare its accuracy and efficiency with manual VAC surveillance SETTING: The intensive care units (ICUs) of 4 hospitals METHODS: This study was conducted at Detroit Medical Center, a tertiary care center in metropolitan Detroit. A total of 128 ICU beds in 4 acute care hospitals were included during the study period from August to October 2013. The automated VAC algorithm was implemented and utilized for 1 month by all study hospitals. Simultaneous manual VAC surveillance was conducted by 2 infection preventionists and 1 infection control fellow who were blinded to each another's findings and to the automated VAC algorithm results. The VACs identified by the 2 surveillance processes were compared. RESULTS: During the study period, 110 patients from all the included hospitals were mechanically ventilated and were evaluated for VAC for a total of 992 mechanical ventilation days. The automated VAC algorithm identified 39 VACs with sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 100%. In comparison, the combined efforts of the IPs and the infection control fellow detected 58.9% of VACs, with 59% sensitivity, 99% specificity, 91% PPV, and 92% NPV. Moreover, the automated VAC algorithm was extremely efficient, requiring only 1 minute to detect VACs over a 1-month period, compared to 60.7 minutes using manual surveillance. CONCLUSIONS: The automated VAC algorithm is efficient and accurate and is ready to be used routinely for VAC surveillance. Furthermore, its implementation can optimize the sensitivity and specificity of VAC identification.

Impact of changes in the NHSN catheter-associated urinary tract infection (CAUTI) surveillance criteria on the frequency and epidemiology of CAUTI in intensive care units (ICUs).

The impact of the 2013 NHSN CAUTI definition on CAUTI rates was analyzed. A total of 107 CAUTI episodes were identified; 60 according to NHSN 2013 definitions only and 47 according to the 2012 and 2013 definitions. Physician-diagnosed "other infections" were more common among patients who had CAUTI only according to NHSN 2013 definitions (P<.001).

Carbapenem-resistant Acinetobacter baumannii: epidemiology, surveillance and management.

Carbapenem-resistant Acinetobacter baumannii pose a significant threat to hospitalized patients, as therapeutic options are scarse. Alarmingly, rates of carbapenem-resistance in A. baumannii are on the rise and are slowly becoming a routine phenotype for this organism. This review focuses on infection control strategies for identification and control of A. baumannii, as well the available therapeutic options.
