Outcomes of patients hospitalized in ward settings for COVID-19 pneumonia with or without early empirical antibiotics.

Background: During the first pandemic of COVID-19, early empirical antibiotic use rates for pneumonia varied widely. The benefit remains hypothetical.

Methods: We assessed the benefit of empirical antibiotic use at admission in patients hospitalized with COVID-19 pneumonia.

Early and short-term intensive management after discharge for patients hospitalized with acute heart failure: a randomized study (ECAD-HF).

Aims: Hospitalization for acute heart failure (HF) is followed by a vulnerable time with increased risk of readmission or death, thus requiring particular attention after discharge. In this study, we examined the impact of intensive, early follow-up among patients at high readmission risk at discharge after treatment for acute HF.

Methods And Results: Hospitalized acute HF patients were included with at least one of the following: previous acute HF < 6 months, systolic blood pressure ≤ 110 mmHg, creatininaemia ≥ 180 µmol/L, or B-type natriuretic peptide ≥ 350 pg/mL or N-terminal pro B-type natriuretic peptide ≥ 2200 pg/mL.

Reliability and Safety of Bedside Blind Bone Biopsy Performed by a Diabetologist for the Diagnosis and Treatment of Diabetic Foot Osteomyelitis.

Objective: Bone biopsy (BB) performed by a surgeon or an interventional radiologist is recommended for suspicion of osteomyelitis underlying diabetic foot ulcer (DFU). To facilitate its practice, we developed a procedure allowing bedside blind bone biopsy (B4) by a diabetologist.

Research Design And Methods: We conducted a three-step observational study consisting of a feasibility and safety phase (phase 1) to assess the success and side effects of B4, a validity phase (phase 2) to compare DFU outcomes between positive (B4+) and negative (B4-) bone cultures, and a performance phase (phase 3) to compare B4 with the conventional surgical or radiological procedure basic bone biopsy (B3).

Intentionality in adherence to long-term therapies. Results from an online survey of 3,001 patients with cardio-metabolic pathologiesin France.

Purpose: Some patients make a rational choice not to follow medical prescriptions; others fail to take their medications for reasons beyond their control, such as mere forgetfulness or a weak medication routine. The aim of this study was to elucidate the functioning of patient intentionality in medication adherence.

Patients And Methods: This online study was conducted in metropolitan France in 2019.

White blood count, D-dimers, and ferritin levels as predictive factors of pulmonary embolism suspected upon admission in noncritically ill COVID-19 patients: The French multicenter CLOTVID retrospective study.

Background: A high prevalence of pulmonary embolism (PE) has been described during COVID-19. Our aim was to identify predictive factors of PE in non-ICU hospitalized COVID-19 patients.

Methods: Data and outcomes were collected upon admission during a French multicenter retrospective study, including patients hospitalized for COVID-19, with a CT pulmonary angiography (CTPA) performed in the emergency department for suspected PE.

D-Dimer Level and Neutrophils Count as Predictive and Prognostic Factors of Pulmonary Embolism in Severe Non-ICU COVID-19 Patients.

The incidence of pulmonary embolism (PE) is high during severe Coronavirus Disease 2019 (COVID-19). We aimed to identify predictive and prognostic factors of PE in non-ICU hospitalized COVID-19 patients. In the retrospective multicenter observational CLOTVID cohort, we enrolled patients with confirmed RT-PCR COVID-19 who were hospitalized in a medicine ward and also underwent a CT pulmonary angiography for a PE suspicion.

Towards individualised and optimalised positioning of non-ventilated COVID-19 patients: Putting the affected parts of the lung(s) on top?

The outbreak of COVID-19 led to an unprecedented inflow of hospitalised patients with severe acute respiratory syndrome (SARS), requiring high-flow non-invasive oxygenation, if not invasive mechanical ventilation. While the best option in terms of non-invasive systems of oxygen delivery is still a matter of debate, it also remains unclear as to whether or not the optimal in-bed positioning of patients might also help to improve their oxygen saturation levels. On the basis of three representative cases, it is possible to propose the following hypotheses: (i) how patients are positioned has a strong influence on their oxygen saturation levels; (ii) saturation-optimalised positions are patient-specific; (iii) prone positions require ergonomic devices; and (iv) saturation-optimalised positions should aim to place the most affected part(s) of the lung(s) on top.

Switching fibrate to statin in type 2 diabetic patients: consequences on lipid profile.

Unlabelled: Interest of statins in terms of morbid-mortality reduction in primary and secondary prevention in type 2 diabetic patients has broadly been proven in recent studies, while evidence for fibrates preventive effect is considerably weaker. HMGCoA reductase inhibitors are known to decrease low density lipoprotein cholesterol (LDL C) in a greater extension than triglycerides (TG). In type 2 diabetic patients, the dyslipidemic profile is commonly associated with reduced high-density lipoproteins (HDL C), increased TG and normal or mildly elevated LDL C.

[Mitochondrial diabetes: clinical features, diagnosis and management].

Mitochondrial diabetes affects up to 1% of patients with diabetes and is often unrecognised by the physicians. Maternally inherited diabetes and deafness (MIDD) resulting from the mutation 3243A>G of the mitochondrial DNA is the most frequent mutation associated with mitochondrial diabetes. This review summarizes the range of clinical phenotypes associated with MIDD and outlines the advances in genetic diagnosis, pathogenesis and management of these patients.

Abnormalities in insulin secretion in type 2 diabetes mellitus.

Type 2 diabetes mellitus is a multifactorial disease, due to decreased glucose peripheral uptake, and increased hepatic glucose production, due to reduced both insulin secretion and insulin sensitivity. Multiple insulin secretory defects are present, including absence of pulsatility, loss of early phase of insulin secretion after glucose, decreased basal and stimulated plasma insulin concentrations, excess in prohormone secretion, and progressive decrease in insulin secretory capacity with time. beta-cell dysfunction is genetically determined and appears early in the course of the disease.

Macular pattern dystrophy in MIDD: long-term follow-up.

A case of maternally inherited diabetes and deafness (MIDD)-associated macular pattern dystrophy with a 15-year follow-up is reported. On initial examination at age 37, visual acuity was normal, but chorioretinal atrophy at the posterior pole was already present in both eyes. At age 52, visual acuity remained normal in the right eye and was only slightly decreased in the left eye despite notable extension of the areas of chorioretinal atrophy in that eye.

Gender and neurogenin3 influence the pathogenesis of ketosis-prone diabetes.

Ketosis-prone diabetes (KPD) is a phenotypically defined form of diabetes characterized by male predominance and severe insulin deficiency. Neurogenin3 (NGN3) is a proendocrine gene, which is essential for the fate of pancreatic beta cells. Mice lacking ngn3 develop early insulin-deficient diabetes.

Muscle infarction in a young woman with brittle type 1 diabetes.

We present the first case of muscle infarction in a 30-year-old woman who had a 5-year history of type 1 diabetes mellitus that was not complicated by nephropathy, retinopathy or neuropathy. All common causes of muscle infarction were excluded, particularly microangiopathy and a hypercoagulable state. The differential diagnosis included infection (pyomyositis, necrotic fasciitis), focal inflammatory myositis, vascular events, trauma, tumor and diabetic amyotrophy, all of which were excluded.

Occurrence of gestational diabetes mellitus, maternal and fetal outcomes beyond the 28th week of gestation in women at high risk of gestational diabetes. A prospective study.

Aim: Among the numerous guidelines defining the diagnostic strategy of gestational diabetes mellitus (GDM), none of them suggest a follow-up in women with risk factors beyond the 28th week of gestation (WG). The primary objective of this study was to assess the incidence of GDM beyond 28 WG in a group of women at high risk. The secondary objectives were to evaluate maternal and fetal outcomes in early and late GDM (between 24-28 WG, and beyond 28 WG), as well as to compare them to a normal glucose tolerance (NGT) group.

Zygomycosis: an uncommon cause for peripheral facial palsy in diabetes.

Mucormycosis is an emerging fungal infection with a high rate of mortality. Diabetic and immuno-compromised patients are the most frequent hosts. We report a case of rhino-orbito-cerebral mucormycosis revealed by facial palsy in a diabetic, immuno-compromised patient with difficult life conditions.

No evidence for left ventricular diastolic dysfunction in asymptomatic normotensive type 2 diabetic patients: a case-control study with new echocardiographic techniques.

Objective: We sought to determine whether abnormalities of left ventricular structure and function could be detected in asymptomatic type 2 diabetic patients free of cardiovascular complications.

Research Design And Methods: We compared 48 subjects with type 2 diabetes (34 men, 50+/-6 years) without hypertension, coronary artery disease and microangiopathic complications with 30 age-matched healthy controls. Left ventricular diastolic function was assessed by conventional Doppler echocardiography and new echocardiographic techniques (tissue Doppler imaging, color M-mode propagation velocity).

[Limits of the Valsalva manoeuvre for the detection of pseudonormal mitral flow].

The pseudonormal mitral profile is difficult to distinguish from a normal profile with echocardiography. Ever since a study showing that the Valsalva manoeuvre could unmask the appearance of relaxation disorders of transmitral flow (E/A < 1) in subjects with cardiopathy, this method has been proposed for the analysis of diastolic function. Very few data exist on the effect of this method in healthy subjects.

High prevalence of glucose-6-phosphate dehydrogenase deficiency without gene mutation suggests a novel genetic mechanism predisposing to ketosis-prone diabetes.

Context: Ketosis-prone diabetes (KPD) is mostly observed in males of West African descent and is characterized by phasic or permanent insulin dependence without apparent autoimmune process.

Objective: KPD subjects display a propensity to hyperglycemia-induced acute insulin deficiency, suggesting that they exhibit a propensity to oxidative stress in beta-cells. The enzyme glucose-6-phosphate dehydrogenase (G6PD) is a defense mechanism against oxidative stress, and G6PD deficiency, an X-linked genetic disorder with male predominance, is frequent in West Africans.
