Terahertz antireflection coatings employing off-the-shelf adhesive tapes.

We demonstrate the feasibility of making antireflection coatings (ARCs) for terahertz (THz) light using multilayered polymer films from commercial adhesive tapes. Efficient and low-cost ARCs in the THz range are not conveniently available. Our economical approach can mitigate many of the experimental challenges posed by Fresnel reflection.

Sodium Bicarbonate Prescription and Extracellular Volume Increase: Real-world Data Results from the AlcalUN Study.

Oral alkalization with sodium bicarbonate (NaHCO ) or citrate is prescribed for conditions ranging from metabolic acidosis to nephrolithiasis. Although most nephrologists/urologists use this method routinely, extracellular volume (ECV) increase is the main feared adverse event reported for NaHCO . Thus far, no trial has specifically studied this issue in a real-world setting.

Skeletal Muscle Index as a Prognostic Marker for Kidney Transplantation in Older Patients.

Objective: Low skeletal muscle mass has emerged as a risk factor for mortality after liver transplantation. We evaluated the prognostic value of muscle mass on length of hospitalization and adverse outcomes after kidney transplantation in aging end-stage renal disease patients.

Methods: One hundred twenty-two patients aged 60 years or older at the time of transplantation were retrospectively analyzed.

Neonatal COVID-19 Pneumonia: Report of the First Case in a Preterm Neonate in Mayotte, an Overseas Department of France.

We report the first case of COVID-19 pneumonia in a preterm neonate in Mayotte, an overseas department of France. The newborn developed an acute respiratory distress by 14 days of life with bilateral ground glass opacities on a chest CT scan and a 6-week-long stay in the neonatal intensive care unit (NICU). This case report emphasizes the need for a cautious and close follow-up period for asymptomatic neonates born to mothers with COVID-19 infection.

An unusually high plasma concentration of homocysteine resulting from a combination of so-called "secondary" etiologies.

The metabolism of homocysteine is complex and involves many enzymes as well as vitamin-derived cofactors. Any dysregulation of this metabolism may lead to hyperhomocysteinemia (HHCy) which is responsible for many clinical disorders including thromboembolic events. HHCy may result from very different etiologies and is generally classified into three groups according to homocysteine concentrations: moderate (<30 µmol/L), intermediate (30-100 µmol/L) or major (>100 μmol/L).

Unilateral nephrectomy versus renal arterial embolization and technique survival in peritoneal dialysis patients with autosomal dominant polycystic kidney disease.

Background: Autosomal dominant polycystic kidney disease (ADPKD) is a common genetic disorder associated with progressive enlargement of the kidneys and liver. ADPKD patients may require renal volume reduction, especially before renal transplantation. The standard treatment is unilateral nephrectomy.

[Obstetrical follow-up and perinatal prognosis in drug addict pregnant women].

Objective: To identify the factors associated with a good obstetric follow-up and a good perinatal prognosis, in order to adapt the management of pregnant women with addiction to opiates.

Methods: A retrospective study was carried out in our maternity between January 2012 and December 2014, including 104 women who were addicted to opiates, whether or not they were substituted, with or without associated consumptions, regardless of the term of delivery beyond 22 weeks of amenorrhea.

Results: A good obstetrical follow-up was observed by 32.

[Bicarbonate: From physiology to treatment for all clinicians].

Acid-base regulation is essential to maintain homeostasis in humans. Carbonic acid/bicarbonate (HCO/HCO) couple is the most predominant extracellular buffer to keep plasma pH within a physiological range. The ability to (re)generate such a buffer is a key milestone that necessitates to understand a precise physiology of both renal tubule and digestive tract.

Signaling of Serum Amyloid A Through Receptor for Advanced Glycation End Products as a Possible Mechanism for Uremia-Related Atherosclerosis.

Objective: Cardiovascular disease is the leading cause of death in patients with end-stage renal disease. Serum amyloid A (SAA) is an acute phase protein and a binding partner for the multiligand receptor for advanced glycation end products (RAGE). We investigated the role of the interaction between SAA and RAGE in uremia-related atherogenesis.

Early Standard Electroencephalogram Abnormalities Predict Mortality in Septic Intensive Care Unit Patients.

Introduction: Sepsis is associated with increased mortality, delirium and long-term cognitive impairment in intensive care unit (ICU) patients. Electroencephalogram (EEG) abnormalities occurring at the acute stage of sepsis may correlate with severity of brain dysfunction. Predictive value of early standard EEG abnormalities for mortality in ICU septic patients remains to be assessed.

[Hyponatremias: From pathophysiology to treatments. Review for clinicians].

Hyponatremia could be defined as a public health topic: too many patients are concerned in both hospitalized and general populations; hyponatremia induces lots of clinical outcomes and a great economic burden. Its pathophysiology involves thirst regulation (hypotonic water intakes) and losses regulation (through the kidney under vasopressin control). Diagnostic approach should insure that hyponatremia reflects hypo-osmolality and hypotonicity: first, a false hyponatremia should be ruled out, then a non-hypotonic one.

Recurrent IgA nephropathy is predicted by altered glycosylated IgA, autoantibodies and soluble CD89 complexes.

IgA nephropathy (IgAN), the most common primary glomerulonephritis worldwide, frequently leads to end-stage renal disease and kidney transplantation. However, disease recurrence often occurs after transplantation. Here we evaluated the predictive value of three markers for IgAN recurrence: the presence of galactose-deficient IgA1, IgG anti-IgA autoantibodies, and IgA-soluble (s) CD89 complexes.

Prevalence of Clostridium species and behaviour of Clostridium botulinum in gnocchi, a REPFED of italian origin.

Sales and consumption of refrigerated processed foods of extended durability (REPFEDs) have increased many-fold in Europe over the last 10 years. The safety and quality of these convenient ready-to-eat foods relies on a combination of mild heat treatment and refrigerated storage, sometimes in combination with other hurdles such as mild preservative factors. The major hazard to the microbiological safety of these foods is Clostridium botulinum.

Growth and germination of proteolytic Clostridium botulinum in vegetable-based media.

The growth of proteolytic Clostridium botulinum from spore inocula and changes in spore counts in mushroom, broccoli, and potato purées were monitored. Four strains of proteolytic C. botulinum types A and B were inoculated separately at approximately 10(4) spores per ml in nutrient broth and vegetable purées incubated at 15, 20, and 30 degrees C for up to 52 days.

Paroxetine versus clomipramine in adolescents with severe major depression: a double-blind, randomized, multicenter trial.

Objective: To date, two randomized, double-blind trials of serotonin reuptake inhibitors (SRIs) have shown that antidepressant drugs are effective in treating adolescent depression. In contrast, tricyclic antidepressants (TCAs) are not superior to placebo. This has led to a serotonin hypothesis in this age group.

[Risk-taking. Adolescent girls versus adolescent boys].

Epidemiologists as well as professionals working in the area of adolescent health generally agree that adolescence is a period characterized by a difference in frequency of risk-taking behaviour between girls and boys. An explanation of these data through ethno-psychological and psychodynamical approaches is hereby presented. Such approaches should be taken into account for general preventive strategies to take effect.
