Invasive mechanical ventilation (IMV) of pre-term infants may be associated with high rate of mortality and iatrogenic complications in low- and middle-income countries. Sustained lung inflation (SLI) may help to reduce their need for IMV.

This randomized controlled trial included 160 infants with gestational age (GA) ≥27 and ≤32 weeks who were randomly assigned to receive either SLI; using a pressure of 20 cmH2O for 15 s followed by nasal continuous positive airway pressure (CPAP) of 5 cmH2O or nasal CPAP alone, through an appropriate mask and a T-piece resuscitator. Primary outcome was the need for IMV in the first 72 h of life.

There was no difference in the primary outcome between SLI group; 55% (44 out of 80) and the control group; 65% (52 out of 80) [odds ratio (OR) 0.623, 95% confidence interval (CI) 0.33-1.18; p = 0.145]. However, SLI significantly reduced the primary outcome in the sicker infants; who had clinical eligibility criteria (CEC; OR 0.224, 95% CI 0.076-0.663; p = 0.005) and in the smaller babies; whose GA was <30 weeks (OR 0.183, 95% CI 0.053-0.635; p = 0.005).

SLI was not harmful. Although, it did not lead to reduction in the need for IMV in the first 72 h of life in pre-term infants with GA ≥27 and ≤32 weeks, SLI reduced this outcome in the subgroup of infants with CEC and those with GA <30 weeks. Future trials are needed to investigate the effect of SLI on these two subgroups.

Some degree of mental distress is commonly present in old age, and it is often exacerbated in later life following changes in physical health. This work presents in two studies among samples that have been exposed to stressful experiences in the past, a prospective examination of how the association between physical health and mental distress is attenuated by two forms of views on aging, evaluations of age and evaluations of one's future.

Study 1 (N = 226) was conducted in 2008 (Time 1) and 2014 (Time 2), among Israeli war veterans (mean age 64.90, SD = 5.04); Study 2 (N = 132) was conducted in 2014 (Time 1) and 2015 (Time 2) among older adults who were exposed to ongoing rocket fire in the south of Israel (mean age 66.44, SD = 9.77). Participants reported on their subjective age, subjective life expectancy (SLE, in Study 1/distance-to-death; DtD, in Study 2), health, and mental distress.

Both studies showed that after controlling for exposure to trauma and for Time 1 mental distress, Time 1 subjective age, but not SLE/DtD, moderated the association between Time 1 physical health and Time 2 mental distress.

Subjective age and SLE represent distinct features of views of aging. Subjective age may reflect perceptions of one's aging process, associated more directly with health-related outcomes over time. SLE reflects future, death-related perceptions, therefore perhaps less directly associated with such outcomes.

The primary objectives of two phase II studies of fostamatinib were to evaluate efficacy (OSKIRA-Asia-1 NCT01569074) and long-term safety/tolerability (OSKIRA-Asia-1X NCT01640054) in patients from Asia with active RA despite MTX treatment.

OSKIRA-Asia-1 was a 12-week, multicentre, double-blind, placebo-controlled, parallel-group study. Patients were randomized to receive one of four fostamatinib doses (groups A-D; n = 31, 33, 33, 33) or placebo (group E; n = 33). OSKIRA-Asia-1X was a long-term extension study (100 mg fostamatinib qd) of patients who completed OSKIRA-Asia-1. RA signs and symptoms were measured by ACR response criteria and DAS based on a 28-joint count. Physical function status was assessed with the HAQ-Disability Index. Safety findings were monitored.

In OSKIRA-Asia-1, fostamatinib revealed numerical improvements in ACR 20% response (ACR20) at week 12 in group A (100 mg bid) and group B (100 mg bid, then 150 mg qd) vs placebo. Statistically significant improvements in ACR20 and ACR50 at week 8 and in ACR70 at week 12, and statistically significant achievement in low disease activity (defined as DAS based on a 28-joint count ≤3.2 based on C-reactive protein) occurred in groups A and B. Improvement in physical function was numerically higher in group A. The most common adverse events were hypertension, diarrhoea and neutropenia. In OSKIRA-Asia-1X, the most common adverse events were nasopharyngitis, hypertension, RA and neutropenia.

Fostamatinib achieved both statistically and clinically significant improvements in RA signs and symptoms. The safety and tolerability of fostamatinib (plus MTX) were consistent with previous studies.

To define key genetic elements, single or in clusters, underlying SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) evolutionary diversification across continents, and their impact on drug-binding affinity and viral antigenicity.

A total of 12 150 SARS-CoV-2 sequences (publicly available) from 69 countries were analysed. Mutational clusters were assessed by hierarchical clustering. Structure-based virtual screening (SBVS) was used to select the best inhibitors of 3-chymotrypsin-like protease (3CL-Pr) and RNA-dependent RNA polymerase (RdRp) among the FDA-approved drugs and to evaluate the impact of mutations on binding affinity of these drugs. The impact of mutations on epitope recognition was predicted following Grifoni et al. (Cell Host Microbe 2020.

671-80.).

Thirty-five key mutations were identified (prevalence ≥0.5%), residing in different viral proteins. Sixteen out of 35 formed tight clusters involving multiple SARS-CoV-2 proteins, highlighting intergenic co-evolution. Some clusters (s reflect geographically dependent SARS-CoV-2 genetic adaptation, and may play a potential role in modulating drug susceptibility and hampering viral antigenicity. Thus, a close monitoring of SARS-CoV-2 mutational patterns is crucial to ensure the effectiveness of treatments and vaccines worldwide.

Epigenetic changes, including abnormal histone and DNA methylation, have been implicated in the pathogenic build-up of hematopoietic progenitors, but it is still unclear whether and how IDH mutations themselves affect hematopoiesis. Here, we show that IDH1-mutant mice develop myeloid dysplasia in that these animals exhibit anemia, ineffective erythropoiesis, and increased immature progenitors and erythroblasts. In erythroid cells of these mice, D-2-hydroxyglutarate, an aberrant metabolite produced by the mutant IDH1 enzyme, inhibits oxoglutarate dehydrogenase activity and diminishes succinyl-coenzyme A (CoA) production. This succinyl-CoA deficiency attenuates heme biosynthesis in IDH1-mutant hematopoietic cells, thus blocking erythroid differentiation at the late erythroblast stage and the erythroid commitment of hematopoietic stem cells, while the exogenous succinyl-CoA or 5-ALA rescues erythropoiesis in IDH1-mutant erythroid cells. Heme deficiency also impairs heme oxygenase-1 expression, which reduces levels of important heme catabolites such as biliverdin and bilirubin. These deficits result in accumulation of excessive reactive oxygen species that induce the cell death of IDH1-mutant erythroid cells. Our results clearly show the essential role of IDH1 in normal erythropoiesis and describe how its mutation leads to myeloid disorders. These data thus have important implications for the devising of new treatments for IDH-mutant tumors.
EUCAST recently advised against temocillin use, except for non-serious urinary tract infections (UTI) caused by Escherichia coli, Klebsiella spp. (except Klebsiella aerogenes) and Proteus mirabilis (EKP) treated with a dose of 2 g q8h. We aimed to analyse our practice in the context of a larger temocillin use in France.

All ≥3 day temocillin prescriptions from 2016 to 2019 were reviewed, with reference to French recommendations and a susceptibility breakpoint of 8 mg/L. The primary outcome was early clinical failure (antibiotic switch, relapse or death within 10 days after the completion of antibiotic treatment).

Overall, 153 cases were analysed 123 cases of UTI (80.4%) and 133 cases of monomicrobial infection with Enterobacterales (86.9%). A total of 160 Enterobacterales were isolated, comprising 108 (67.5%) ESBL producers and 30 (20.7%) non-EKP species. The rate of early clinical failure was 9.2% and was significantly lower for UTI compared with non-UTI (4.9% versus 26.7%, P = 0.001) and for sepsis compared with severe sepsis or septic shock (6.2% versus 25%, P = 0.011). It was not different between 2 g q12h and 2 g q8h doses (10% versus 7.4%, P = 0.81) and between EKP and other Enterobacterales (8.7% versus 14.3%, P = 0.41).

EUCAST recommendations on urinary isolates seem to be too restrictive. Our data support the efficacy of temocillin at a dose of 2 g q12h to treat patients with non-severe complicated UTI caused by MDR Enterobacterales with an MIC of ≤8 mg/L, whatever the species.

Significant morbidity and mortality in patients with sickle cell disease are accounted for by lung complications. To facilitate good respiratory care for children with sickle cell anaemia the generation of local predicted values is highly important.

To determine the reference equations for spirometry indices estimation in children with sickle cell anaemia, which can be readily used as proxy when there is no easy accessibility to spirometer.

A cross-sectional study with linear regression models developed to estimate reference values for spirometric indices in Nigerian children with sickle cell anaemia aged 5-12 years.

Age as independent variables for estimation of forced expiratory volume in 1 s (FEV1) was associated with lowest coefficient of determination (R2) and highest standard error. The coefficient of determination (R2) and standard error was highest and lowest, respectively, when arm span was used to determine peak expiratory flow rate (PEFR). Prediction models for PEFR and FEV1 gave the closest mean estimates that were 0.
