French-language questionnaires in ENT: Inventory and review.

OBJECTIVE: Patient-Reported Outcome Measures (PROMs) are now an integral part of clinical and academic practice in ENT, and it is essential to have tools with a validated French version. However, there are no guidelines on ENT questionnaires available in French or those that could have transcultural adaptation. METHODS: The present study, under the auspices of the ENT National Professional Council and the French Society of ENT, inventoried PROMs, for each super-specialty and pathology, meeting one of the following inclusion criteria: validated French version, not translated but used internationally (i.e., translated into other languages and widely cited since 2017), or subjectively deemed useful by experts in the super-specialty in question. RESULTS: In total, 103 questionnaires were identified. To encourage and accompany their intercultural adaptation and statistical validation, this article presents the rationale and methodology of such an undertaking. CONCLUSION: PROMs either already validated in French or which it would be useful to translate were inventoried. The methodology of translation and validation to guarantee reliability and relevance is presented.

Burnout in ENT France: Update and risk factors; a STROBE analysis.

BACKGROUND: Burnout can significantly impact practitioners and their co-workers, and hence patients. There are no data for the prevalence of burnout in French ENT specialists, or for associated risk factors. MATERIAL AND METHODS: A French national cross-sectional online survey was performed on the initiative of the ENT National Professional Council (CNPORL), contacting all ENT specialists whose e-mail address was known to the French Society of ENT, the National Professional Council or the National ENT Union. The 22-question Maslach Burnout Inventory (MBI) was sent out, along with 16 extra questions on possible risk factors. OBJECTIVES: The study sought to assess the prevalence and severity of burnout, using the MBI, and to analyze risk factors. RESULTS: Among the 1936 physicians, 406 contacted responded to the questionnaire (21%). Mean age was 47±14 years (range, 25-77 years); 53% male, 47% female. 196 (48%) reported burnout, including 20 (5%) severe burnout. Independent risk factors for burnout of whatever severity, comprised social interaction issues, history of identified burnout, and medicolegal pressures. Social interaction issues were independently associated with specifically severe burnout. CONCLUSIONS: Burnout affected almost half of respondents. There are identifiable risk factors, for which improvements could be implemented.

French adaptation and validation of the Stapesplasty Outcome Test (SPOT-25), following COSMIN guidelines.

AIMS: Otosclerosis can severely impact quality of life, but no questionnaire is available in French. The present study aimed to adapt and validate a French version of the SPOT-25. MATERIALS AND METHODS: A controlled prospective study was conducted between September 2021 and April 2022. The translation used the "forward-backward" technique and statistical validation was performed in non-operated adult otosclerosis patients (cases) and a control group. Assessment Internal consistency, discrimination performance and test-retest reliability were assessed on global score, subscores and items. RESULTS: Fifty-one cases and 58 control subjects filled out the test questionnaire and 35 of the 51 cases, also filled out the retest. Internal consistency on Cronbach alpha was 0.95 for the cases. Median total SPOT-25 score was 44 (range, 10-78) for cases and 2 (range, 0-33) for controls (p= P<0.0001). Test-retest reliability on intraclass correlation coefficient was excellent (ICC=0.92; [95% CI, 0.84-0.96]). Individual items all showed satisfactory performance. CONCLUSION: The French version of SPOT-25 was short and easy to use, with satisfactory performance in assessing quality of life in otosclerosis patients.

Pancreatic ß-cell imaging in humans: fiction or option?

Diabetes mellitus is a growing worldwide epidemic disease, currently affecting 1 in 12 adults. Treatment of disease complications typically consumes ∼10% of healthcare budgets in developed societies. Whilst immune-mediated destruction of insulin-secreting pancreatic ß cells is responsible for Type 1 diabetes, both the loss and dysfunction of these cells underly the more prevalent Type 2 diabetes. The establishment of robust drug development programmes aimed at ß-cell restoration is still hampered by the absence of means to measure ß-cell mass prospectively in vivo, an approach which would provide new opportunities for understanding disease mechanisms and ultimately assigning personalized treatments. In the present review, we describe the progress towards this goal achieved by the Innovative Medicines Initiative in Diabetes, a collaborative public-private consortium supported by the European Commission and by dedicated resources of pharmaceutical companies. We compare several of the available imaging methods and molecular targets and provide suggestions as to the likeliest to lead to tractable approaches. Furthermore, we discuss the simultaneous development of animal models that can be used to measure subtle changes in ß-cell mass, a prerequisite for validating the clinical potential of the different imaging tracers.

Human-IAPP disrupts the autophagy/lysosomal pathway in pancreatic ß-cells: protective role of p62-positive cytoplasmic inclusions.

In type II diabetes (T2DM), there is a deficit in ß-cells, increased ß-cell apoptosis and formation of intracellular membrane-permeant oligomers of islet amyloid polypeptide (IAPP). Human-IAPP (h-IAPP) is an amyloidogenic protein co-expressed with insulin by ß-cells. IAPP expression is increased with obesity, the major risk factor for T2DM. In this study we report that increased expression of human-IAPP led to impaired autophagy, due at least in part to the disruption of lysosome-dependent degradation. This action of IAPP to alter lysosomal clearance in vivo depends on its propensity to form toxic oligomers and is independent of the confounding effect of hyperglycemia. We report that the scaffold protein p62 that delivers polyubiquitinated proteins to autophagy may have a protective role against human-IAPP-induced apoptosis, apparently by sequestrating protein targets for degradation. Finally, we found that inhibition of lysosomal degradation increases vulnerability of ß-cells to h-IAPP-induced toxicity and, conversely, stimulation of autophagy protects ß-cells from h-IAPP-induced apoptosis. Collectively, these data imply an important role for the p62/autophagy/lysosomal degradation system in protection against toxic oligomer-induced apoptosis.

Biguanides and thiazolidinediones inhibit stimulated lipolysis in human adipocytes through activation of AMP-activated protein kinase.

AIMS/HYPOTHESIS: In rodent adipocytes, activated AMP-activated protein kinase reduces the lipolytic rate. As the hypoglycaemic drugs metformin and thiazolidinediones activate this enzyme in rodents, we tested the hypothesis that in addition to their known actions they could have an anti-lipolytic effect in human adipocytes. METHODS: Adipose tissue was obtained from individuals undergoing plastic surgery. Adipocytes were isolated and incubated with lipolytic agents (isoprenaline, atrial natriuretic peptide) and biguanides or thiazolidinediones. Lipolysis was quantified by the glycerol released in the medium. AMP-activated protein kinase activity and phosphorylation state were determined using standard procedures. RESULTS: In human adipocytes, isoprenaline and atrial natriuretic peptide stimulated the lipolytic rate three- to fourfold. Biguanides and thiazolidinediones activated AMP-activated protein kinase and inhibited lipolysis by 30-40%, at least in part by inhibiting hormone-sensitive lipase translocation to the lipid droplet. Inhibition of AMP-activated protein kinase by compound C precluded this inhibitory effect on lipolysis. Stimulation of lipolysis also induced an activation of AMP-activated protein kinase concomitant with a drop in ATP concentration. CONCLUSIONS/INTERPRETATION: We show for the first time in human adipocytes that biguanides and thiazolidinediones activate AMP-activated protein kinase, thus counteracting lipolysis induced by lipolytic agents. In addition, beta-agonist- or ANP-stimulated lipolysis increases AMP-activated protein kinase activity. This is because of an increase in the AMP/ATP ratio, linked to activation of some of the released fatty acids into acyl-CoA. AMP-activated protein kinase activation could represent a physiological means of avoiding a deleterious drain of energy during lipolysis but could be used to restrain pharmacological release of fatty acids.

[Objective tinnitus and essential palatal tremor in children: report of a case]. / Acouphènes objectifs et myoclonies vélaires: à propos d'un cas chez l'enfant.

Palatal tremor is a rare neurotological disorder responsible for objective tinnitus in children. Palatal tremor may be symptomatic of an underlying neurological disease or essential when a cause cannot be identified. We report a case of an essential palatal tremor in a 10-year-old girl complaining of clicking tinnitus. No treatment was undergone as she was not obviously bothered by the ear-clicking sound. Different treatment modalities have been used for distressing tinnitus related to palatal myoclonus. Recently several publications reported satisfactory results with botulinum toxin injection, which seems to be the treatment of choice.
