Insect decline: immediate action is needed.

Insects appeared more than 400 million years ago and they represent the richest and most diverse taxonomic group with several million species. Yet, under the combined effect of the loss of natural habitats, the intensification of agriculture with massive use of pesticides, global warming and biological invasions, insects show alarming signs of decline. Although difficult to quantify, species extinction and population reductions are confirmed for many ecosystems.

Impact of Angiotensin-Converting Enzyme Inhibitors and Angiotensin II Receptor Blockers in Hypertensive Patients with COVID-19 (COVIDECA Study).

Effect of angiotensin-converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB) among hypertensive patients with coronavirus disease 2019 (COVID-19) is debated. The aim of the COVIDECA study was to assess the outcome of ACEI and ARB among hypertensive patients presenting with COVID-19. We reviewed from the Assistance Publique-Hôpitaux de Paris healthcare record database all patients presenting with confirmed COVID-19 by RT-PCR.

Intravenous Artesunate for the Treatment of Severe Imported Malaria: Implementation, Efficacy, and Safety in 1391 Patients.

Background: Intravenous artesunate is the World Health Organization-recommended first-line treatment for severe malaria worldwide, but it is still not fully licensed in Europe. Observational studies documenting its safety and efficacy in imported malaria are thus essential.

Methods: We prospectively collected clinical and epidemiological features of 1391 artesunate-treated patients among 110 participant centers during the first 7 years (2011-2017) of a national program implemented by the French Drug Agency.

Why the Risk of Developing Neuroarthropathy Is Higher After Simultaneous Kidney and Pancreatic Transplantation Compared to Kidney Transplantation Only: The Role of Euglycemia.

Charcot's neuroarthropathy is a destructive complication of the joint, which is often found in patients living with diabetes. Despite the fact that its description was published almost 100 years ago, its pathophysiology, diagnosis, and treatment remain areas that need to be updated. Its prevalence is low in patients living with diabetes, but this increases in particular situations such as peripheral neuropathy, as well as after simultaneous kidney-pancreas transplantation (SPKT) in patients living with type 1 diabetes.

Association of Intravenous Immunoglobulins Plus Methylprednisolone vs Immunoglobulins Alone With Course of Fever in Multisystem Inflammatory Syndrome in Children.

Importance: Multisystem inflammatory syndrome in children (MIS-C) is the most severe pediatric disease associated with severe acute respiratory syndrome coronavirus 2 infection, potentially life-threatening, but the optimal therapeutic strategy remains unknown.

Objective: To compare intravenous immunoglobulins (IVIG) plus methylprednisolone vs IVIG alone as initial therapy in MIS-C.

Design, Setting, And Participants: Retrospective cohort study drawn from a national surveillance system with propensity score-matched analysis.

Coronavirus Disease 2019 Pandemic: Impact Caused by School Closure and National Lockdown on Pediatric Visits and Admissions for Viral and Nonviral Infections-a Time Series Analysis.

A time series analysis of 871 543 pediatric emergency visits revealed that the coronavirus disease 2019 (COVID-19) lockdown and school closures were associated with a significant decrease in infectious diseases disseminated through airborne or fecal-oral transmission: common cold, gastroenteritis, bronchiolitis, and acute otitis. No change was found for urinary tract infections.

References were assessed according to a predefined process to propose recommendations with the corresponding levels of evidence.

PRODIGE 59-DURIGAST trial: A randomised phase II study evaluating FOLFIRI + Durvalumab ± Tremelimumab in second-line of patients with advanced gastric cancer.

Gastric or gastro-oesophageal junction (GEJ) adenocarcinomas present poor overall survival (OS). First-line chemotherapy regimen for patients with HER2-negative tumours is based on a doublet or triplet of fluoropyrimidine plus platinum salt ± taxane. Second-line chemotherapy (Docetaxel or Irinotecan) improves OS which nonetheless remains poor (around 5 months).

Hyperacute Recanalization Strategies and Childhood Stroke in the Evidence Age.

No controlled pharmacological studies are available in the field of pediatric stroke, except for sickle cell disease. Therefore, while pharmacological and mechanical recanalization treatments have repeatedly shown clinical benefit in adults with arterial ischemic stroke, pediatric strokologists still cannot base their therapeutic management (including hyperacute strategies) on high-level evidence. Once again, pediatricians face the same dichotomic choice: adapting adult procedures now versus waiting-for a long time-for the corresponding pediatric trials.

Factors Associated With Severe SARS-CoV-2 Infection.

Background: Initial reports on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in children suggested that very young age and comorbidities may increase risk of severe evolution, but these findings remained to be confirmed. We aimed to analyze the clinical spectrum of hospitalized pediatric SARS-CoV-2 infection and predictors of severe disease evolution.

Methods: We conducted a French national prospective surveillance of children hospitalized with SARS-CoV-2 infection.

Cytosolic sequestration of the vitamin D receptor as a therapeutic option for vitamin D-induced hypercalcemia.

The bioactive vitamin D, 1α,25(OH)D, plays a central role in calcium homeostasis by controlling the activity of the vitamin D receptor (VDR) in various tissues. Hypercalcemia secondary to high circulating levels of vitamin D leads to hypercalciuria, nephrocalcinosis and renal dysfunctions. Current therapeutic strategies aim at limiting calcium intake, absorption and resorption, or 1α,25(OH)D synthesis, but are poorly efficient.

Glacial heterogeneity in Southern Ocean carbon storage abated by fast South Indian deglacial carbon release.

Past changes in ocean C disequilibria have been suggested to reflect the Southern Ocean control on global exogenic carbon cycling. Yet, the volumetric extent of the glacial carbon pool and the deglacial mechanisms contributing to release remineralized carbon, particularly from regions with enhanced mixing today, remain insufficiently constrained. Here, we reconstruct the deglacial ventilation history of the South Indian upwelling hotspot near Kerguelen Island, using high-resolution C-dating of smaller-than-conventional foraminiferal samples and multi-proxy deep-ocean oxygen estimates.

DTPA-Coated Liposomes as a New Delivery Vehicle for Plutonium Decorporation.

Administration of diethylenetriaminepentaacetic acid (DTPA) is the treatment approach used to promote the decorporation of internalized plutonium. Here we evaluated the efficacy of PEGylated liposomes coated with DTPA, primarily designed to prevent enhanced plutonium accumulation in bones, compared to marketed nonliposomal DTPA and liposomes encapsulating DTPA. The comparative effects were examined in terms of reduction of activity in tissues of plutonium-injected rats.

Human dentin characteristics of patients with osteogenesis imperfecta: insights into collagen-based biomaterials.

Osteogenesis imperfecta (OI), also known as "brittle bone disease", is a rare genetic disorder of the skeleton, whose most benign form I corresponds to autosomal dominant mutations in the genes encoding type I collagen (COLA1, COLA2). Several associated skeletal manifestations are often observed but, surprisingly, while dentin defects often reflect genetic bone disorders, about half of OI patients have no obvious oral manifestations. Here, we investigated the collagen, mineral and mechanical properties of dentin from deciduous teeth collected from patients with mild form of OI and displaying no obvious clinical signs of dentinogenesis imperfecta.

Mild dyserythropoiesis and β-like globin gene expression imbalance due to the loss of histone chaperone ASF1B.

The expression of the human β-like globin genes follows a well-orchestrated developmental pattern, undergoing two essential switches, the first one during the first weeks of gestation (ε to γ), and the second one during the perinatal period (γ to β). The γ- to β-globin gene switching mechanism includes suppression of fetal (γ-globin, HbF) and activation of adult (β-globin, HbA) globin gene transcription. In hereditary persistence of fetal hemoglobin (HPFH), the γ-globin suppression mechanism is impaired leaving these individuals with unusual elevated levels of fetal hemoglobin (HbF) in adulthood.
