In patients with hypoxemic acute respiratory failure (ARF), randomized studies have shown noninvasive positive pressure ventilation (NPPV) to be associated with lower rates of endotracheal intubation. In these patients, predictors of NPPV failure are not well characterized. To investigate variables predictive of NPPV failure in patients with hypoxemic ARF. Prospective, multicenter cohort study. Eight Intensive Care Units (ICU) in Europe and USA. Of 5,847 patients admitted between October 1996 and December 1998, 2,770 met criteria for hypoxemic ARF. Of these, 2,416 were already intubated and 354 were eligible for the study. NPPV failed in 30% (108/354) of patients. The highest intubation rate was observed in patients with ARDS (51%) or community-acquired pneumonia (50%). The lowest intubation rate was observed in patients with cardiogenic pulmonary edema (10%) and pulmonary contusion (18%). Multivariate analysis identified age > 40 years (OR 1.72, 95% CI 0.92-3.23), a simplified acute physiologic score (SAPS II) > or = 35 (OR 1.81, 95% CI 1.07-3.06), the presence of ARDS or community-acquired pneumonia (OR 3.75, 95% CI 2.25-6.24), and a PaO2:FiO2 < or = 146 after 1 h of NPPV (OR 2.51, 95% CI 1.45-4.35) as factors independently associated with failure of NPPV. Patients requiring intubation had a longer duration of ICU stay ( P < 0.001), higher rates of ventilator-associated pneumonia and septic complications ( P < 0.001), and a higher ICU mortality ( P < 0.001). In hypoxemic ARF, NPPV can be successful in selected populations. When patients have a higher severity score, an older age, ARDS or pneumonia, or fail to improve after 1 h of treatment, the risk of failure is higher.

Objective: To assess the ability of the SOFA score (Sequential Organ Failure Assessment) to describe the evolution of organ dysfunction/failure in trauma patients over time in intensive care units (ICU). Design: Retrospective analysis of a prospectively collected database. Setting: 40 ICUs in 16 countries. Patients: All trauma patients admitted to the ICU in May 1995. Main outcome measures and results: Incidence of dysfunction/failure of different organs during the first 10 days of stay and the relation between the dysfunction, outcome, and length of stay. Included in the SOFA study were 181 trauma patients (140 males and 41 females).The non-survivors were significantly older than the survivors (51 years ± 20 vs 38 ± 16 years, p < 0.05) and had a higher global SOFA score on admission (8 ± 4 vs 4 ± 3, p < 0.05) and throughout the 10-day stay. On admission, the non-survivors had higher scores for respiratory ( > 3 in 47 % of non-survivors vs 17 % of survivors), cardiovascular ( > 3 in 24 % of non-survivors vs 5.7 % of survivors), and neurological systems ( > 4 in 41 % of non-survivors vs 16 % of survivors); although the trend was maintained over the whole study period, the differences were greater during the first 4-5 days. After the first 4 days, only respiratory dysfunction was significantly related to outcome. A higher SOFA score, admission to the ICU from the same hospital, and the presence of infection on admission were the three major variables associated with a longer length of stay in the ICU (additive regression coefficients: 0.85 days for each SOFA point, 4.4 for admission from the same hospital, 7.26 for infection on admission). Conclusions: The SOFA score can reliably describe organ dysfunction/failure in trauma patients. Regular and repeated scoring may be helpful for identifying categories of patients at major risk of prolonged ICU stay or death.[PUBLICATION ABSTRACT]

For several decades, many efforts have been dedicated to enhancing the accuracy of mortar radiocarbon dating and evaluating the reliability of the results concerning the typology of the examined specimens. Several assumptions that are fundamental for the application of the method may be in many cases not fulfilled, such as (a) complete primary limestone dissociation during calcination, (b) efficient separation of geogenic carbon contained in calcareous aggregates, (c) short carbonation time, and (d) absence of secondary calcite. Many laboratories all over the world have proposed different methods to select suitable fractions of mortar. The first intercomparison attempt, involving eight international laboratories, was organized in 2016 aiming at comparing and statistically treating the results obtained on the same materials by different laboratories with their own characterization and pre-treatment methods (Hajdas et al. 2017; Hayen et al. 2017). Following this first step, a new intercomparison experiment was proposed and set up in 2018 during the Mortar Dating International Meeting (Bordeaux, FR). A new set of three mortar samples was chosen, taking care of the selection of standardized materials (homogeneity, known mineralogical composition, absence of exogenous inclusions, known expected age). This work describes the results of two research teams involved in the intercomparison. The samples were characterized, selected, and dated depending on each laboratory strategy. The results stress the importance of the characterization of the raw material is to better understand the mineralogical and petrographical composition of the samples. Such information can support the choice of the most appropriate strategy for the extraction of CO2 and then for data interpretation.

The PREMEDI study was designed to assess the efficacy of nutritional counseling aimed at promoting Mediterranean Diet (MD) during pregnancy on the incidence of overweight or obesity at 24 months in the offspring. PREMEDI was a parallel-arm randomized-controlled trial. 104 women in their first trimester of pregnancy were randomly assigned in a 1:1 ratio to standard obstetrical and gynecological care alone (CT) or with nutritional counseling promoting MD. Women enrolled in the MD arm were provided with 3 sessions of nutritional counseling (one session per trimester). The main outcome was the proportion of overweight or obesity among the offspring at the age of 24 months. Maternal MD-adherence and weight gain during pregnancy were also evaluated. Lastly, the evaluation of epigenetic modulation of metabolic pathways in the offspring was analyzed in cord blood. Five women in the MD arm and 2 in the CT arm were lost to follow-up, so a total of 97 completed the study. At 24 months, children of MD mothers were less likely to have overweight or obesity than those of the CT mothers (6% vs. 30%, absolute risk difference = -24%, 95% CI -38% to -9%, p = 0.003, number needed to treat 4, 95% CI 2 to 12, per-protocol analysis). A significantly higher increase of MD-adherence during the trial was observed in the MD arm compared to the CT arm. A similar body weight gain at the end of pregnancy was observed in the two arms. The mean (SD) methylation rate of the leptin gene in cord blood was 30.4 (1.02) % and 16.9 (2.99) % in the MD and CT mothers, respectively (p < 0.0001). MD during pregnancy could be an effective strategy for preventing pediatric overweight or obesity at 24 months. This effect involves, at least in part, an epigenetic modification of leptin expression.

The Istituto Nazionale di Fisica Nucleare—Laboratori Nazionali del Gran Sasso (LNGS) is one of the largest underground physics laboratory, a very peculiar environment suited for experiments in Astroparticle Physics, Nuclear Physics and Fundamental Symmetries. The newly established Bellotti Ion Beam facility represents a major advance in the possibilities of studying nuclear processes in an underground environment. A workshop was organized at LNGS in the framework of the Nuclear Physics Mid Term Plan in Italy, an initiative of the Nuclear Physics Division of the Instituto Nazionale di Fisica Nucleare to discuss the opportunities that will be possible to study in the near future by employing state-of-the-art detection systems. In this report, a detailed discussion of the outcome of the workshop is presented.

Objective To compare the efficacy of five probiotic preparations recommended to parents in the treatment of acute diarrhoea in children. Design Randomised controlled clinical trial in collaboration with family paediatricians over 12 months. Setting Primary care. Participants Children aged 3-36 months visiting a family paediatrician for acute diarrhoea. Intervention Children's parents were randomly assigned to receive written instructions to purchase a specific probiotic product: oral rehydration solution (control group); Lactobacillus rhamnosus strain GG; Saccharomyces boulardii; Bacillus clausii; mix of L delbrueckii var bulgaricus, Streptococcus thermophilus, L acidophilus, and Bifidobacterium bifidum; or Enterococcus faecium SF68. Main outcome measures Primary outcomes were duration of diarrhoea and daily number and consistency of stools. Secondary outcomes were duration of vomiting and fever and rate of admission to hospital. Safety and tolerance were also recorded. Results 571 children were allocated to intervention. Median duration of diarrhoea was significantly shorter (P<0.001) in children who received L rhamnosus strain GG (78.5 hours) and the mix of four bacterial strains (70.0 hours) than in children who received oral rehydration solution alone (115.0 hours). One day after the first probiotic administration, the daily number of stools was significantly lower (P<0.001) in children who received L rhamnosus strain GG and in those who received the probiotic mix than in the other groups. The remaining preparations did not affect primary outcomes. Secondary outcomes were similar in all groups. Conclusions Not all commercially available probiotic preparations are effective in children with acute diarrhoea. Paediatricians should choose bacterial preparations based on effectiveness data. Trial registration number Current Controlled Trials ISRCTN56067537.
