Psychiatric Deprescribing: A Narrative Review.

Objective: Psychiatric deprescribing is an intervention where psychiatric medications are reduced or discontinued with the goal to improve health and reduce unnecessary risks. The purpose of this study was to synthesize the literature related to psychiatric deprescribing to discuss practice and research implications.

Methods: A structured search of the literature was conducted from May to September 2022, yielding 29 articles meeting inclusion criteria.

Diet Quality Is an Indicator of Disease Risk Factors in Hispanic College Freshmen.

Background: No studies have assessed the relationship between diet quality, using the Healthy Eating Index (HEI), and adiposity, physical activity, and metabolic disease risk factors in a Hispanic college population.

Objective: To assess associations between diet quality and adiposity, metabolic health, and physical activity levels in a Hispanic college freshman population.

Design: This was a cross-sectional study.

Decreased eating frequency linked to increased visceral adipose tissue, body fat, and BMI in Hispanic college freshmen.

Background: To investigate the relationship between eating frequency and specific adiposity markers in a potentially high-risk and understudied population of Hispanic college freshmen.

Methods: This study included 92 Hispanic college freshmen (18-19 y). The following cross-sectional data were collected: height, weight, waist circumference, body mass index (BMI), dietary intake, body composition, physical activity, hepatic fat, visceral adipose tissue (VAT), and subcutaneous adipose tissue (SAT).

[Interest of a sterilised anti-burning gel in radiation dermatitis: results of a comparative study].

Trial objectives were to assess effectiveness and tolerance of sterilized Avène thermal spring water anti burning gel (ATSW gel) in prevention of radiation dermatitis in adults irradiated (6 weeks) for breast (n=61) or head and neck (n=8) cancer. Patients included in this open labelled, 2 parallel groups, multicentric study, were randomly assigned to apply five times daily for ten weeks either the Avène spring water gel (n=35) or trolamine cream (n=34). The median of emergence of the first objective radiation dermatitis signs was 31 days in the ATSW gel group and 29 days in the control group (p=0,924).

Evaluation of residual and therapeutic doses of tetracycline in the human-flora-associated (HFA) mice model.

In order to evaluate an in vivo model system for assessing the effect of therapeutic and residue levels of tetracycline on human intestinal microflora, tetracycline was administered via drinking water (1, 10, and 100 mg/liter) to human-flora-associated (HFA) male and female mice. The effects of the antibiotic on fecal aerobic and anaerobic populations, selection of bacteria resistant to tetracycline, metabolic parameters of the microflora, and maintenance of the intestinal barrier against exogenous Salmonella (resistance to colonization) were recorded. In both sexes of mice, tetracycline exposure at 10 and 100 mg/liter induced the selection of several resistant bacterial species (Gram-positive anaerobes, Bacteroides fragilis, enterobacteria, and enterococci).

New trends in regulatory rules and surveillance of antimicrobial resistance in bacteria of animal origin.

Since the introduction in the 1940s of antibiotics as drugs against bacterial infections in human and then veterinary medicine, two major events have caused a shift in the antibiotherapy era: (1) the emergence of resistant bacteria and (2) the awareness of the limits of new drug development. It rapidly became urgent to set up measures in order to evaluate the importance of resistant bacteria and their origin as well as to limit the dissemination of resistant vectors (bacteria and bacterial genes). This led to the establishment of guidelines and regulatory rules necessary for risk assessment and clearly dependent upon monitoring and research organisations.

Elimination of aminoglycoside antibiotics in milk following intramammary administration.

The elimination in cow milk of aminoglycoside antibiotic residues (neomycin, dihydrostreptomycin, kanamycin and gentamicin) was studied after intramammary administration of eight drug formulations marketed in France. Quantitative residue analysis was performed by a cylinder plate method. The sensitivity was 0.

Basis for the evaluation of the microbiological risks due to veterinary drug residues in food.

The history of the establishment of safe residue levels is reviewed. Current international agreements within the FAO/WHO Codex Alimentarius programme and EC legislation establish these levels on the basis of toxicology studies. In addition to conventional toxicological effects, other effects such as the effects of drugs on the immune system, and pharmacological effects should be taken into account.

Excretion of penicillins and cephalexin in bovine milk following intramammary administration.

The elimination into bovine milk of beta-lactam antibiotic residues (procaine penicillin G, cloxacillin, ampicillin, oxacillin, cephalexin) following intramammary administration of 10 preparations marketed in France was studied. The quantitative analysis of residues was carried out by a microbiological agar diffusion method using Bacillus stearothermophilus. Sensitivity ranged from 0.

Excretion of tetracycline and chlortetracycline in eggs after oral medication of laying hens.

After dosing laying hens orally with tetracycline (TC) through either drinking water (0.25 and 0.5 g/l for 5 days) or feed (300 and 600 ppm for 7 days), and chlortetracycline (CTC) through feed (600 ppm) residues were determined by an agar plate diffusion technique in cylinders with Bacillus cereus as test-organism, separately for albumen and for yolk.

Excretion of oxytetracycline in eggs after medication of laying hens.

The kinetics of oxytetracycline elimination into eggs were determined separately for albumen and yolk after oral administration through either drinking water (0.1-0.25 and 0.

[Elimination of polypeptide antibiotics (colistin and bacitracin) in the milk after intramuscular or intramammary administration].

The elimination in cow's milk of polypeptidic antibiotic residues (colistin sulfate, colistin methanesulfonate and bacitracin) was investigated following intramuscular and intramammary administrations of eight drugs marketed in France. The quantitative analysis was performed according to the microbiological method of agar diffusion. The mean elimination periods lasted between three and six milkings for injected preparations, between four and six milkings for intramammary ones.

Excretion of penicillins in bovine milk following intramuscular administration.

The kinetics of elimination into milk of sodium penicillin G, procaine penicillin G, benzathine penicillin G, ampicillin and amoxycillin residues have been determined after intramuscular administration of eleven drugs chosen among those commercially available in France. These investigations will be used as a basis to estimate and harmonize the withdrawal times demanded for veterinary drugs. The quantitative analysis of residues was carried out by a cylinder plate microbiological method with Bacillus stearothermophilus as test organism.

[A survey on the use of antibiotics in veterinary medicine (author's transl)].

Many problems about public health are raised by the use of antiinfectious agents in veterinary medicine. Particular attention must be given to the contamination of human food of animal origin and to the exposure of workers manufacturing these drugs. A review of the use of these products in veterinary medicine, particularly that of antibiotics will allow to circumscribe the problems due to drugs which might cause allergy.

[General schema for safety evaluation of residues of embryotoxic drugs (author's transl)].

Concerned with adapting the withdrawal time to real risks attributed to residues, the authors present a general schema of evaluation based on the metabolism-toxicity relationship. This schema takes into account: a) possible distinction between potentially toxic and atoxic metabolites for extractable residues, b) the more or less large biovailability of residues, c) the methodological evaluation difficulties of toxicity of bound residues. Without neglecting public health, this procedure leads to less constrained restrictions in use of veterinary drugs.

High-pressure liquid chromatographic analysis of veterinary anthelmintics I: Quantitative determination of tetramisole.

High-pressure liquid chromatography was used with a 10-micron C8-type bonded silica gel column to quantitate the tetramisole in veterinary anthelmintic preparations. The chromatographic elution time was less than 10 min, and other compounds present in the products analyzed did not interefere.
