Abstract
INTRODUCTION Pulmonary segmentectomy is becoming increasingly widespread but remains technically challenging. The aim of this study was to evaluate the impact of the surgical approach applied on postoperative complications after pulmonary segmentectomy. METHODS All patients having undergone pulmonary segmentectomy by thoracotomy, videothoracoscopy or robot-assisted surgery from 1st January 2018 to 31st December 2021 were included. The primary endpoint was the occurrence of postoperative complications. Secondary endpoints were operative time, length of hospital stay, 30-day readmission rate, 30-day and 90-day mortality. RESULTS Two hundred and twenty-three patients were included, 30% (n=67) in the thoracotomy group, 9.4% (n=21) in the videothoracoscopy group and 60.5% (n=135) in the robot-assisted surgery group. There was no difference in the occurrence of postoperative complications according to type of approach (P=0.564), 26.9% of patients (n=60) had at least one postoperative complication. There was no significant difference between the groups in terms of operative time (P=0.385), length of hospital stay (P=0.107), 30 and 90-day mortality (P=0.124 and P=0.249, respectively). Mini-invasive surgery significantly reduced the 30-day readmission rate (P=0.049). CONCLUSION The surgical approach applied does not influence the postoperative complications of pulmonary segmentectomy.

A specific tongue microbiota signature is found in patients displaying an improvement of orosensory lipid perception after a sleeve gastrectomy. Front Nutr 2023; 9:1046454.

Abstract
Introduction A preferential consumption of low-fat foods is reported by most of the patients after a vertical sleeve gastrectomy (VSG). The fact that a recent study shed light on a relationship between oral microbiota and fat taste sensitivity in obese patients prompted us to explore whether such a connection also exists in the context of a VSG. Methods Thirty-two adult female patients with a severe obesity (BMI = 43.1 ± 0.7 kg/m2) and candidates for a VSG were selected. Oral microbiota composition surrounding the gustatory circumvallate papillae (CVP) and the lipid perception thresholds were explored before and 6 months after surgery. Results VSG was found to be associated both with a qualitative (compositional changes) and quantitative (lower gene richness) remodeling of the peri-CVP microbiota. Analysis of the lipid perception allowed us to distinguish two subgroups: patients with a post-operative improvement of the fat taste sensitivity (i.e., with a lower threshold, n = 14) and unimproved patients (n = 18). Specific peri-CVP microbiota signatures also discriminated these two subgroups, unimproved patient being characterized by higher levels of Porphyromonas, Fusobacterium, and Haemophilus genera associated with lower levels of Atopobium and Prevotella genera as compared to the lipid-improved patients. Conclusion Collectively, these data raise the possibility that the microbial environment surrounding gustatory papillae might play a role in the positive changes of fat taste sensitivity observed in some patients after VSG.

Abstract
Abstract
Background
Evidence on the impact of simulation-based training in transesophageal echocardiography (TEE) is scarce.
Purpose
We aimed to assess the efficacy of simulation-based versus traditional teaching on TEE knowledge and skills for cardiology residents.
Methods
Between November 2020 and November 2021, all consecutive cardiology residents inexperienced from TEE were randomised (1:1, n=324) through 42 French University Centers into two groups with or without simulation support (either a simulation group or a traditional group). The coprimary outcomes were the scores in the final theoretical and practical tests 3 months after the training. TEE duration and the feelings of residents were also assessed. An economic analysis was also performed.
Results
While the theoretical and practical test scores were similar between the two groups before the training (respectively P=0.80 and P=0.51), the residents in the simulation group displayed higher theoretical test and practical test scores after the training than those in the traditional group (respectively 47.2±15.6% vs. 38.3±19.8%, P<0.0001 and 74.5±17.7% vs. 59.0±25.1%, P<0.0001). Subgroups analyses showed that the efficacy of the simulation training was even greater when performed at the beginning of residency (P<0.0001). After the training, the duration to perform a complete TEE was significantly lower in the simulation group than in the traditional group (respectively 8.3±1.4 min vs. 9.4±1.2 min, P<0.0001). Finally, residents' feelings were better in the simulation group than in the traditional group across all components (P<0.0001). Compared to the traditional group, the average additional cost per resident of the simulation program was respectively €1,785, €942 or €662 for 20, 40 and 60 residents.
Conclusion
Simulation-based teaching on TEE showed a significant improvement in knowledge, skills, and feelings of cardiology residents as well as a reduction in the duration to complete the examination.

Abstract
Meniscal tear in the knee joint is a highly common injury that can require an ablation. However, the success rate of meniscectomy is highly impacted by difficulties in estimating the thin vascularization of the meniscus, which determines the healing capacities of the patient. Indeed, vascularization is estimated using arthroscopic cameras that lack of high sensitivity to blood flow. Here, we propose an ultrasound method for estimating the density of vascularization in the meniscus during surgery. This approach uses an arthroscopic probe driven by ultrafast sequences. To enhance the sensitivity of the method, we propose to use a chirp-coded excitation combined with a mismatched compression filter robust to the attenuation. This chirp approach was compared to a standard ultrafast emission and a Hadamard-coded emission using a flow phantom. The mismatched filter was also compared to a matched filter. Results show that, for a velocity of a few millimeters per second, the mismatched filter gives a 4.4-10.4-dB increase of the signal-to-noise ratio (SNR) compared to the Hadamard emission and a 3.1-6.6-dB increase compared to the matched filter. Such increases are obtained for a loss of axial resolution of 13% when comparing the point spread functions (PSFs) of the mismatched and matched filters. Hence, the mismatched filter allows increasing significantly the probe capacity to detect slow flows at the cost of a small loss in axial resolution. This preliminary study is the first step toward an ultrasensitive ultrasound arthroscopic probe able to assist the surgeon during meniscectomy.

Abstract
Abstract
Background
Patients with hypertrophic cardiomyopathy (HCM) have high risk of death related to cardiovascular (CV) death. Improvements in risk stratification are needed to help identify those HCM patients at higher risk of all-cause death and cardiovascular death.
Methods
This French longitudinal cohort study from the database covering hospital care from 2010 to 2019 analyzed adultshospitalized with isolated HCM. The overall sample of 52,091 patients was randomly partitioned into derivation (n=26,067) and validation (n=26,024) populations. A logistic regression model was used to construct HCM death and CV-death scores in the derivation sample, which were compared to the Charlson index, Frailty index and CHA2DS2VASc scores using c-indexes and calibration analysis.
Results
In 52,091 patients with isolated HCM, 12,676 (24.0%) died during follow-up of 3.0±2.8 years (median 2.3, interquartile range 0.4–5.0). Rate of all-cause death was 8.10%/year (7.96–8.24) and was 2.76%/year (2.68–2.84) for CV death.Independent predictors of CV death in HCM were older age, diabetes mellitus, heart failure, history of pulmonary edema, atrial fibrillation, ventricular tachycardia or fibrillation, ischemic stroke, while smoking and poor nutrition were associated with better survival (all p<0.05). In addition to these, male sex, vascular disease, alcohol related diagnoses, kidney disease, lung disease, liver disease anemia and cancer were independent predictors of all-cause death. In the derivation cohort, c-indexes for the HCM death score were 0.720 (0.713–0.727) for all-cause death and 0.695 (0.685–0.705) for CV death. For the HCM CV-death score, c-indexes were 0.679 (0.671–0.686) for all-cause death and 0.723 (0.712–0.733) for CV death. Performances were very similar in the validation cohort. Both scores had good calibrations. Charlson and Frailty indexes however had a better clinical usefulness than the HCM death score and HCM CV-death scores for predicting all-cause death. Decision curve analysis for CV death demonstrated that the HCM CV-death score had the best clinical usefulness of all the tested risk scores.
Conclusion
HCM patients have a high risk of all-cause and CV mortality. Independent predictors of CV-mortality in HCM were used to derive and validate a simple risk prediction model (French HCM CV-mortality score) which performed better than clinical scores, Charlson Index and Frailty Index; showing the best clinical usefulness, with good calibration.

Abstract
BACKGROUND Readmission within 30 days is an indicator of the quality of care, because it often reflects post-discharge care that is not optimal. The objective of this work is to measure over time on the one hand the readmission rate and on the other hand the number of hospitals with a standardized readmission rate beyond the national average. METHOD All patients with major pulmonary resection for lung cancer in France were extracted from the PMSI national database. Readmission within 30 days was defined as any new hospitalization either in the same hospital or in another establishment. RESULTS From January 1, 2005 to December 31, 2018, 110,603 patients were included. The 30-day all-cause readmissions rate was 24.9% (n=27,540). Patients after pneumonectomy had a readmission rate of 37% (n=4918) and 23% after lobectomy (n=2684) (P<0.0001). For the first period, we counted 10 hospitals with a standardized readmissions rate above the 99.8 limit and 10 hospitals above the 95% limit. For the second period, 8 hospitals had a standardized readmission rate above the 99.8% limit and 11 hospitals above the 95% limit. For the third period, 7 hospitals had a standardized readmission rate above the 99.8% limit and 6 hospitals above the 95% limit. CONCLUSION Readmissions to hospital 30 days after major lung resection for cancer in France declined little during these three periods. Measures to prevent readmissions should be introduced.

Abstract
Diet-induced obesity (DIO) reduces the orosensory perception of lipids in rodents and in some humans. Although bariatric surgery partially corrects this alteration, underlying mechanisms remain poorly understood. To explore whether metabolic changes might explain this fat taste disturbance, plasma metabolome analyses, two-bottle choice tests and fungiform papillae (Fun) counting were performed in vertical sleeve gastrectomized (VSG) mice and sham-operated controls. An exploratory clinic study was also carried out in adult patients undergone a VSG. In mice, we found that (i) the VSG reduces both the plasma neurotoxic signature due to the tryptophan/kynurenine (Trp/Kyn) pathway overactivation and the failure of fat preference found in sham-operated DIO mice, (ii) the activity of Trp/Kyn pathway is negatively correlated to the density of Fun, and (iii) the pharmacological inhibition of the Kyn synthesis mimics in non-operated DIO mice the positive effects of VSG (i.e., decrease of Kyn synthesis, increase of Fun number, improvement of the fat taste perception). In humans, a reduction of the plasma Kyn level is only found in patients displaying a post-surgery improvement of their fat taste sensitivity. Altogether these data provide a plausible metabolic explanation to the degradation of the orosensory lipid perception observed in obesity.

Orosensory Perception of Fat/Sweet Stimuli and Appetite-Regulating Peptides before and after Sleeve Gastrectomy or Gastric Bypass in Adult Women with Obesity. Nutrients 2021; 13:nu13030878.

Abstract
The aim of this study was to explore the impact of bariatric surgery on fat and sweet taste perceptions and to determine the possible correlations with gut appetite-regulating peptides and subjective food sensations. Women suffering from severe obesity (BMI > 35 kg/m2) were studied 2 weeks before and 6 months after a vertical sleeve gastrectomy (VSG, n = 32) or a Roux-en-Y gastric bypass (RYGB, n = 12). Linoleic acid (LA) and sucrose perception thresholds were determined using the three-alternative forced-choice procedure, gut hormones were assayed before and after a test meal and subjective changes in oral food sensations were self-reported using a standardized questionnaire. Despite a global positive effect of both surgeries on the reported gustatory sensations, a change in the taste sensitivity was only found after RYGB for LA. However, the fat and sweet taste perceptions were not homogenous between patients who underwent the same surgery procedure, suggesting the existence of two subgroups: patients with and without taste improvement. These gustatory changes were not correlated to the surgery-mediated modifications of the main gut appetite-regulating hormones. Collectively these data highlight the complexity of relationships between bariatric surgery and taste sensitivity and suggest that VSG and RYGB might impact the fatty taste perception differently.

Introduction
Aortic Stenosis (AS) is a common condition in patients over 75 years. Latest ESC recommendations differentiate 4 types of AS according to: Indexed Stroke Volume (SVi), mean gradient and left ventricular ejection fraction (LVEF). The aim of our study is to evaluate prognosis of patients who have had a transcatheter aortic valve replacement (TAVR), in terms of mortality, according to the 4 types of AS.
Methods
This study compares prognosis of 620 patients who had TAVR between January 1, 2015 and December 31, 2018. Patients were classified into 4 groups according to AS type: high gradient; low gradient, low flow, low LVEF; low gradient, low flow, normal LVEF; low gradient, normal flow.
Results
69 patients (11.1%) died within 12 months of the procedure: 49 in the high gradient group (9.4%); 13 in the low gradient, low flow, low LVEF group (47.1%); 1 in the low gradient, low flow, normal LVEF group (5%); 6 in the low gradient, normal flow, normal LVEF group (18.2%). All-cause mortality at one year follow-up is higher in low-gradient, low-flow, altered LVEF group (p = 0.0004) than in other groups. Patients in this group were significantly more often admitted for heart failure than patients in high-gradient group (p = 0.009).
Conclusion
A complete echocardiography evaluation is needed to evaluate AS, its severity and type. Patients in the low gradient, low flow, low LVEF group have an independent risk of mortality at 12 months higher than other groups and are more hospitalized than patients in the high gradient group.

Abstract
BACKGROUND The beneficial effect of a climatic treatment in children with asthma was established quite some time ago, but the mechanism of this beneficial effect has not been fully elucidated. We investigated the role of the cytokines of the TH2 pathway, reactive oxygen species (ROS) and reactive nitrogen species (RNS) over the course of a high-altitude climatic therapy. METHODS A group of 67 children originating from various French towns suffering from uncontrolled severe asthma was sent via their medical specialists, to the Briançon climatic area. They were monitored over the course of an entire school year. During this time, they returned home for 15 days during the Christmas holidays. At each stage, assessment of asthma control, lung function examination (peak flow meter and spirometry), and measurement of exhaled NO, ROS and RNS in exhaled breath condensate (EBC), and the level of cytokines in the plasma of the TH2 pathway were carried out. RESULTS The degree of asthma control improved at high altitude and worsened upon returning home. The average value of the peak expiratory flow also improved during the first 3 months but then worsened upon returning home, while the other spirometric parameters did not change. The level of expired NO and the scores for quality of life underwent a similar change. The level of RNS and ROS in the EBC did not change significantly. Besides, a marked and statistically significant decrease in the level of IL-13 and IL-10 was noted. CONCLUSION The beneficial effect of a climatic stay of children suffering from allergic asthma at altitude appears to be linked with less allergenic stimulation.

Abstract
AIMS Type 2 diabetes leads to multiple sensory dysfunctions affecting notably the gustatory sensitivity. Although this sensory defect, by impacting food choices, might lead to unhealthy eating behavior, underlying mechanisms remains poorly studied. We have recently reported that the composition of microbiota in contact with circumvallate gustatory papillae might affect the orosensory perception of lipids in lean and normoglycemic obese subjects. This finding has prompted us to explore whether such a phenomenon also occurs in diabetic obese patients. METHODS The composition of microbiota surrounding the circumvallate papillae was analyzed in combination with the linoleic acid perception thresholds in male insulin-resistant patients and weight-matched healthy controls. Two complementary comparisons were performed: (1) controls vs diabetic and (2) diabetic low-lipid tasters versus diabetic high-lipid tasters. RESULTS Despite subtle modifications in the oral microbiota composition, comparison of orosensory lipid perception in controls and diabetic subjects did not lead to discriminating data due to the large inter-individual variability of linoleic acid perception thresholds. In contrast, specific bacterial signatures were found by comparing diabetic low- and high-lipid tasters leading to differential molecular pathways. Surprisingly, a lower fatty taste perception was mainly found in patients treated with metformin and/or statins, suggesting a possible side effect of these antidiabetic and/or hypolipidemic drugs on taste acuity. CONCLUSIONS Collectively, these data show that the diabetic patients with defective fatty taste detection are characterized by a specific microbiota metabolism at the circumvallate papillae levels, this occurrence seeming amplified by drugs commonly used to counteract the damaging metabolic effects of T2D.

Abstract
Abstract
Background
The significance and the management of coronary artery disease (CAD) are disputed in patients treated by transcatheter aortic valve implantation (TAVI). In the presence of a significant CAD eligible for percutaneous coronary intervention (PCI), the issue of the timing of PCI relative to TAVI is unsettled. To answer this question, the present study aimed at comparing the short-term and long-term outcome in patients treated by staged PCI within a 90-day time interval before or after TAVI.
Methods
Based on the French administrative hospital-discharge database, the study collected information for all consecutive patients treated with TAVI between 2014 and 2018. Patients treated with PCI in the preceding 90 days before the TAVI procedure (pre-TAVI PCI) or subsequent 90 days after the TAVI procedure (post-TAVI PCI) were included. All-cause mortality, cardiovascular mortality, stroke, myocardial infarction and a combined cardiovascular endpoint were assessed at 30 days after the last procedure (short-term) and during the whole follow-up (long-term). Propensity score matching was used for the analysis of outcomes.
Results
8613 patients met the inclusion criteria with a vast majority of pre-TAVI PCI patients (N=8324) as opposed to post-TAVI PCI (N=229). After propensity score matching, 2 groups of 227 patients with comparable characteristics were obtained. At 30 days, no significant difference was observed for any of the outcome tested with the exception of myocardial infarction more frequent in post-TAVI PCI (OR 2.43 [1.17–5.07]). After a mean [SD] follow-up of 459 [569] days, all outcomes were identical between subgroups. The figure below illustrates the Kaplan Meier curve for all-cause mortality.
Conclusions
Our study based on a French nationwide database shows that PCI is performed pre-TAVI in a majority of cases, with no significant impact on outcome. Deferring PCI after TAVI seems safe and may provide an opportunity to make the decision on more objective parameters while the stenosis has been removed (such as FFR or IFR). In any case, the timing of PCI relative to TAVI does not seem to represent a concern and should be decided on an individual basis.

Abstract
Abstract
Background
Prediction of operative risk in patients with aortic stenosis (AS) undergoing surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI) remains a challenge, particularly in high-risk patients. The EuroSCORE II is now commonly used to improve risk prediction. Large analyses from administrative database have provided opportunities for conducting health research in the field of structural heart disease interventions but may have a lack of granularity and do not routinely include EuroSCORE II, which may result in a risk of uncontrolled biases. We sought to approximate the EuroSCORE II using only administrative claims data to enable the operative risk to be assessed without clinical or paraclinical performance measures.
Methods
Based on the administrative hospital-discharge database, we collected information for all patients with AS treated with SAVR or TAVI between 2010 and 2019 in France. A total of 78,085 SAVR and 60,821 patients with AS treated with transcatheter aortic valve replacement (TAVR) were found in the database. For each patient, the EuroSCORE II was estimated using the formulas available at the EuroSCORE website. Age, gender, extracardiac arteriopathy, poor mobility, previous cardiac surgery, chronic lung disease, active endocarditis, diabetes on insulin, recent MI, dialysis are items available in the PMSI database using the ICD-10 or CCAM codes. For renal impairment, NYHA class, LVEF, pulmonary hypertension, “critical preoperative state” and urgent intervention, different proxies were built based on ICD-10 codes likely to represent increasing severity of these items.
Results
In the cohort of patients with SAVR, mean estimated EuroSCORE II was 3.3±1.1 while all-cause death at day 30 after SAVR was 3.8%. In the cohort of patients with TAVI, mean estimated EuroSCORE II was 3.8±1.0 while all-cause death at day 30 after TAVI was 5.5%. In the whole cohort, the area under the curve (AUC) of the estimated EuroSCORE II for predicting the risk of all-cause death at day 30 was 0.72 (95% CI 0.71–0.73) and was higher in patients treated with SAVR (AUC 0.76, 95% CI 0.75–0.77) than in those treated with TAVI (AUC 0.67, 95% CI 0.65–0.68, p<0.00001 for DeLong test). The observed versus predicted risks of all-cause death at day 30 post-TAVI OR SAVR within risk deciles are shown in Figure 1. Calibration of the prediction score was satisfying across the 10 deciles and a predicted 30-day mortality rate of approximately 15%.
Conclusions
Claims data alone can be used to identify individuals with AS at operative risk when they are considered for SAVR or TAVI. The Claims-based EuroSCORE II might be used in research with large datasets for confounding adjustment or risk prediction. It provides hospitals and health systems with a low-cost, systematic way to identify a group of patients who are at greater risk of adverse outcomes with these interventions and for whom a more specific approach might be useful.

Reducing Inappropriate Overutilization of the Massive Transfusion Protocol. Am J Clin Pathol 2020.

Abstract
Abstract
Introduction/Objective
Massive transfusion protocols (MTPs) make it possible to deliver blood products to exsanguinating patients in an efficient, sustained, and immediate manner. However, overutilization of MTPs continues to remain a significant problem for hospital blood banks. The study aims to address the characteristics of possibly inappropriate MTP activations during the first phase (cooler) at a level 1 trauma academic medical center.
Methods
This was a retrospective review of 328 phase 1 MTPs out of 696 total MTPs performed during a two-year period (Jan 1, 2017 and Dec 31, 2018) and divided into three categories: trauma, non-trauma surgery, and medicine services. We assumed that a possibly inappropriate MTP for trauma cases would show an Assessment of Blood Component (ABC) score of 1 or less and physicians used clinical discretion. For possibly inappropriate MTP non- trauma surgical and medicine cases, we devised a new system where we looked at only whether the blood pressure was equal to or less than 90 mm Hg and/or the pulse was greater than or equal to 120 beats per minute. If there was a score of 0 where there were neither vital sign criteria, then the MTP was considered possibly inappropriate.
Results
For trauma service, there were 43/168 (25.6%) cases that had an ABC score of 0, 49/168 (29.2%) cases that had an ABC score of 1, 53/168 (31.5%) cases that had an ABC score of 2, 21/168 (12.5%) cases that had an ABC score of 3, and only 2/168 (1.2%) case that had an ABC score of 4. Non-trauma surgery service had 31/51 (60.8%) cases with a new score of 0, 20/51 (39.2%) cases with a new score of 1, and 0/51 (0%) cases with a new score of 2. Medicine services had 57/109 (52.3%) patients with a new score of 0, 47/109 (43.1%) patients with a new score of 1, and 5/109 (4.6%) patients with a new score of 2. Non-trauma surgery service had the greatest possibly inappropriate MTP activations [31/51 cases (60.8%)], followed by trauma [92/168 (54.8%) cases] and medicine [57/109 (52.3%) cases].
Conclusion
Our study shows greater overutilization with MTPs using clinical judgment than with using the ABC criteria. Non-trauma surgery service had the greatest number of possibly inappropriate MTP activations at our hospital without having a significantly abnormal pulse or blood pressure. While ABC criteria is already liberal for activating an MTP, physician discretion appears to be more liberal in activating a possibly inappropriate MTP.

Abstract
PURPOSE Handicap evaluation in adults with acquired or progressive congenital visual loss allows for identification of the individual's specific needs and targeted therapy (medical, technical, rehabilitative and psychological). Currently, the subjective dimension of the handicap remains poorly explored in the field of visual loss. Our questionnaire aims to understand the whole of these subjective impacts. It differs from existing quality of life scales in ophthalmology in its approach centered on the process of adaptation, individual resources (technical, cognitive, psychic and environmental), and investigation of the perception of the handicap. The goal of the present study is to validate this questionnaire, which could be used in any adult with a visual handicap, regardless of the extent of the visual loss, its etiology, or the type of treatment or compensatory mechanisms. MATERIALS AND METHODS The Assessment Questionnaire on the Perception of and Adaptation to Visual Handicap in Adults (QUEPAHVA) is composed of 28 items relating to perception of the visual impairment, its impact, and adaptive resources. They are divided into 3 sub-categories: perception of daily life and relationships (10 items), Perception of visual status and compensatory mechanisms (8 items), and Psychological impact of the visual handicap (10 items). The responses are graded on a Likert scale. Factor analysis and verification of psychometric qualities were performed based on the responses of 446 subjects. The discriminatory validity of the NEI-VFQ 25 was proven with 99 subjects. Reliability over time (mean interval between T1 and T2=49.43 days) was measured in 31 subjects. Sensitivity to change between pre- and post-management (mean interval between T1 and T2=410 days) was tested in 123 subjects. RESULTS Internal consistency was very good for the global scale (α=.90) as well as for the 3 sub-dimensions (α=.86; α=.79; α=.80). The discriminatory validity was satisfactory (r=.70). This result had to be interpreted as a function of the qualitative specificity of the questionnaire. The questionnaire enjoyed good reproducibility over time with regard to its total score and relatively satisfactory reproducibility with regard to its sub-dimensions. Sensitivity to change was very high and accounted for adaptations to the disability over time. CONCLUSION The QUEPAHVA displays good psychometric qualities. It constitutes a new means of evaluation. Its potential applications are many. It permits evaluation of the needs of the individual and adaptation of the protocol of care. Its use in institutions may support a step forward in the science of evaluation and continued improvement in quality of care.

Diet-Induced Obesity Alters the Circadian Expression of Clock Genes in Mouse Gustatory Papillae. Front Physiol 2020; 11:726.

Abstract
Diet-induced obesity (DIO) is associated with a defect of the orosensory detection of dietary lipids in rodents. This dysfunction is not anecdotic since it might worsen the negative effects of obesity by promoting the overconsumption of energy-dense foods. Previous studies have highlighted a progressive devaluation of reward value of lipid stimuli due to a desensitization of dopaminergic brain areas in DIO mice. Paradoxically, the putative deleterious impact of obesity on peripheral fat detection by the gustatory papillae remains poorly documented. Using a whole transcriptomic investigation of the circumvallate papillae (CVP), an analysis of CVP genes involved in fat taste transduction and signaling along the day, and two bottle choice tests, we have found that (i) CVP, known to house the most taste buds in the oral cavity, displays a genic circadian rhythm, (ii) DIO reduces the oscillation of key genes involved both in the circadian clock and lipid detection/signaling, and (iii) the gene invalidation of the clock gene Rev-Erbα does not significantly affect fat preference despite an oily solution intake slightly lower than littermate controls. Taken together these data bring the first demonstration that the gustatory function is under control of a peripheral clock in mammals, as already reported in fly and suggest that a disturbance of this rhythmicity might contribute to the lower fatty taste acuity found in obese mice.

Abstract
Gout is a chronic disease due to the deposition of monosodium urate microcrystals in joints and tissues. Its incidence and prevalence are increasing worldwide in close relation with the epidemic of obesity and metabolic syndrome. Gout is related to chronic hyperuricemia that should be treated to ensure the reduction or even the disappearance of acute attacks ("gout flares") and to reduce the size and number of tophi. If arthritis of the first metatarsophalangeal joint is the most typical form, other joints may be affected, including the spine. Demonstration of urate microcrystals arthritis allows diagnosis of gout but, in the absence of possibility of performing joint puncture, imaging may be useful for providing complementary diagnostic elements. Appropriate care is essential to reduce the number of flares and the evolution towards gouty arthropathy but also in terms of public health in order to reduce costs related to this pathology.

Abstract
OBJECTIVES Transcatheter aortic valve implantation (TAVI) is an alternative to surgical aortic valve replacement (AVR) in aortic stenosis (AS). Infective endocarditis (IE) in patients with prosthetic heart valves is associated with significant morbidity and mortality. Data on the incidence, risk factors, and outcomes of IE after TAVI are conflicting. We evaluated these issues in patients with percutaneous TAVI vs. isolated surgical AVR (SAVR) at a nationwide level. METHODS Based on the administrative hospital discharge database, the study collected information for all patients with aortic stenosis treated with AVR in France between 2010 and 2018. RESULTS A total of 47 553 patients undergoing TAVI and 60 253 patients undergoing isolated SAVR were identified. During a mean follow-up of 2.0 years (median (25th to 75th percentile) 1.2 (0.1-3.4) years), the incidence rates of IE were 1.89 (95% confidence interval (CI) 1.78-2.00) and 1.40 (95% CI 1.34-1.46) events per 100 person-years in unmatched TAVI and SAVR patients, respectively. In 32 582 propensity-matched patients (16 291 with TAVI and 16 291 with SAVR), risk of IE was not different in patients treated with TAVI vs. SAVR (incidence rates of IE 1.86 (95% CI 1.70-2.04) %/year vs 1.71 (95% CI 1.58-1.85) %/year respectively, relative risk (RR) 1.09, 95% CI 0.96-1.23). In these matched patients, total mortality was higher in TAVI patients with IE (43.0% 95% CI 37.3-49.3) than in SAVR patients with IE (32.8% 95% CI 28.6-37.3; RR 1.32, 95% CI 1.08-1.60). DISCUSSION In a nationwide cohort of patients with AS, treatment with TAVI was associated with a risk of IE similar to that following SAVR. Mortality was higher for patients with IE following TAVI than for those with IE following SAVR.

Abstract
Abstract
Patients undergoing transcatheter aortic valve replacement (TAVR) may have concomitant mitral regurgitation (MR). The impact of MR at baseline or after TAVR on subsequent prognosis remains to be more precisely determined. We analysed the impact of MR before or after TAVR on prognosis in the systematic analysis of patients treated with TAVR at a nationwide level.
Methods
Based on the French administrative hospital-discharge database, the study collected information for all consecutive patients with aortic stenosis treated with transfemoral TAVR in France between 2008 and 2018. Cox regression was used for the analysis of predictors of events during follow-up.
Results
A total of 47,872 patients with transfemoral TAVR were included in the analysis (mean age 83±7 years). Moderate/severe MR was present at baseline (MRb) in 9.5% of the patients. Few patients (1.6%) revealed moderate/severe MR post-TAVR (MRpt). Mean follow-up was 1.31±1.61 years. MRb was associated with an increased cardiovascular mortality (Hazard ratio 1.29, 95% CI 1.20–1.39) and total mortality (Hazard ratio 1.15, 95% CI 1.10–1.21). However, MRb was not an independent predictor in multivariable analysis, neither for cardiovascular mortality (adjusted HR 1.06, 95% CI 0.98–1.14) nor for total mortality (adjusted HR 1.01, 95% CI 0.96–1.07). MRpt was not a predictor of cardiovascular or total mortality. Older age, male sex, history of pulmonary edema/cardiogenic shock, atrial fibrillation, myocardial infarction, diabetes, renal failure, liver disease, pulmonary disease, previous cancer and anemia at baseline independently predicted mortality during follow-up. All of them (but history of cancer) were also independent predictor of cardiovascular death.
Conclusion
Baseline MR was associated with increased cardiovascular and totality mortality following TAVR but was not an independent predictor of any of them. By contrast, several other predictors of cardiovascular and total mortality were identified. This suggests that MR should not be directly considered to establish the strategy for TAVR decision or for avoiding TAVR-related futility.

Abstract
Abstract
Risk-benefit assessment for transcatheter aortic valve replacement (TAVR) is still a matter of debate. A sizeable group of patients do not fully benefit from intervention despite a technically successful procedure. We therefore sought to identify patients with a bad outcome early after the procedure, and to develop a prediction model and calculator for identification of these patients.
Methods
Based on the French administrative hospital-discharge database, the study collected information for all consecutive patients with aortic stenosis treated with transfemoral TAVR in France between 2008 and 2018. Multivariate logistic regression was used to select the risk factors of early all-cause death in first year after TAVR procedure (considered as futility) for the overall population. Score points were assigned to each risk factor using the β coefficient. Internal validation was performed by a bootstrap method. Calibration was assessed with the Hosmer-Lemeshow goodness of fit test and accuracy with the C-statistic.
Results
A total of 47,872 patients with transfemoral TAVR were included in the analysis (mean age 83±7 years). Mean follow-up was 1.31±1.61 years and 9,338 deaths were recorded (yearly rate 14.9%), among which 4,562 (49%) occurred in first year after TAVR procedure. The final logistic regression model included older age, male sex, history of hospital stay with heart failure, history of acute pulmonary oedema, atrial fibrillation, previous stroke, vascular disease, diabetes, renal disease, liver disease, pulmonary disease, anemia, history of cancer, metastasis and denutrition,. The area under the curve (AUC) for the score was 0.696 (95% CI 0.688–0.704). This score outperformed frailty index and Charlson comorbidity index for identifying futility. AUC was 0.677 (95% CI 0.669–0.86) for internal validation. The Hosmer–Lemeshow goodness of fit test had a p-value of 0.10 suggesting that the model was accurate. We further divided the model into 4 groups with 5%, 12%, 19% and 30% futility, respectively. The low-risk group consisted of 60% of the patients and the high-risk group consisted of 4% of these patients.
Conclusion
This futility prediction score established from a large nationwide cohort of patients treated with TAVR may provide a relevant insight for optimizing healthcare decision. It may facilitate identification of patients who, despite an apparently successful procedure, have risk of death that may outweigh the benefit of an anticipated TAVR.

Abstract
OBJECTIVE An original device for exploring taste-guided reward behavior in rodents using a newly designed computer-controlled liquid delivery system equipped with "lickometers" is described. METHODS This octagonal shaped "gustometer" is composed of eight shutters that give random access during a few seconds to eight bottles delivering different liquid stimuli. This original design, which forces the animal to move for access to the drinking source, allows a simultaneous analysis of the licking behavior and motivation to drink. Determination of the sucrose licking behavior in diet-induced obese mice was used to validate this method because nutritional obesity disturbs the sweet taste perception in rodents. RESULTS A rise in sucrose response threshold and a decrease in the motivation to drink sweet solutions were found in mice fed the obesogenic diet. These data were highly reproducible among independent studies and corroborated the existence of functional links between diet-induced obesity and gustation in rodents. CONCLUSIONS The FRM-8 gustometer appears to be especially suitable for exploring determinants of behavioral outputs in response to oro-sensory stimuli in the mouse. It also provides substantial information on the taste-reward relationship, useful for better understanding the origin of gustatory efficiency or, conversely, dysfunction, as reported in nutritional obesity.

[PMID: 30279038 DOI: 10.1016/j.clon.2018.09.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2018] [Revised: 07/03/2018] [Accepted: 08/22/2018] [Indexed: 11/30/2022]
Abstract
AIMS Select patients with brain metastases receive stereotactic radiosurgery (SRS) with the objective of improving survival and intracranial disease control. Brain metastases number and volume are prognostic factors used to inform patient selection. The aim of this study was to assess the rate of change of brain metastases size and number (growth kinetics) between the diagnostic and day of SRS magnetic resonance imaging (MRI) scans. MATERIALS AND METHODS All patients treated with Gamma Knife SRS between October 2015 and April 2017 were included in this single-centre retrospective analysis. Brain metastases number and diameter were recorded at diagnosis and treatment. For patients with multiple brain metastases, the largest lesion was the index lesion. Distant intracranial control and overall survival were reported from the date of SRS. RESULTS In total, 146 patients received 156 episodes of SRS. The median interval between diagnostic and SRS MRI was 20 days (range 1-68). Interval growth in the index lesion of at least 3 mm or the development of a new brain metastasis was noted in 60.2% of patients. This was associated with age less than 60 years (P = 0.001), Eastern Cooperative Oncology Group (ECOG) performance status 2 or above (P = 0.04), non-small cell lung carcinoma (NSCLC) (P = 0.03) or melanoma histologies (P = 0.05) and uncontrolled extracranial disease (P = 0.05). These patients were also more likely to develop distant intracranial recurrence (P = 0.046). Clinically significant growth was not associated with scan interval or differences in overall survival. The Kaplan-Meier estimate of probability of survival at 12 months was 59.3% (95% confidence interval 46.7-75.2%) for all patients. CONCLUSION Intracranial progression between diagnosis and day of SRS is common. Risk factors are uncontrolled extracranial disease, poorer performance status, NSCLC or melanoma histologies and age less than 60 years. These patients would benefit from an MRI closer to treatment to inform patient selection and target delineation for SRS planning.

Abstract
BACKGROUND AND PURPOSE The presentation of Parkinson's disease patients with mutations in the LRRK2 gene (PDLRRK2 ) is highly variable, suggesting a strong influence of modifying factors. In this context, inflammation is a potential candidate inducing clinical subtypes. METHODS An extensive battery of peripheral inflammatory markers was measured in human serum in a multicentre cohort of 142 PDLRRK2 patients from the MJFF LRRK2 Consortium, stratified by three different subtypes as recently proposed for idiopathic Parkinson's disease: diffuse/malignant, intermediate and mainly pure motor. RESULTS Patients classified as diffuse/malignant presented with the highest levels of the pro-inflammatory proteins interleukin 8 (IL-8), monocyte chemotactic protein 1 (MCP-1) and macrophage inflammatory protein 1-β (MIP-1-β) paralleled by high levels of the neurotrophic protein brain-derived neurotrophic factor (BDNF). It was also possible to distinguish the clinical subtypes based on their inflammatory profile by using discriminant and area under the receiver operating characteristic curve analysis. CONCLUSIONS Inflammation seems to be associated with the presence of a specific clinical subtype in PDLRRK2 that is characterized by a broad and more severely affected spectrum of motor and non-motor symptoms. The pro-inflammatory metabolites IL-8, MCP-1 and MIP-1-β as well as BDNF are interesting candidates to be included in biomarker panels that aim to differentiate subtypes in PDLRRK2 and predict progression.

Analysis of a swimmer's hand and forearm in impulsive start from rest using computational fluid dynamics in unsteady flow conditions. J Biomech 2017; 67:157-165. [PMID: 29269003 DOI: 10.1016/j.jbiomech.2017.12.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2017] [Revised: 10/19/2017] [Accepted: 12/04/2017] [Indexed: 11/25/2022]
Abstract
The propulsive forces generated by the hands and arms of swimmers have so far been determined essentially by quasi-steady approaches. This study aims to quantify the temporal dependence of the hydrodynamic forces for a simple translation movement: an impulsive start from rest. The study, carried out in unsteady numerical simulation, couples the calculation of the lift and the drag on an expert swimmer hand-forearm model with visualizations of the flow and flow vortex structure analysis. The results of these simulations show that the hand and forearm hydrodynamic forces should be studied from an unsteady approach because the quasi-steady model is inadequate. It also appears that the delayed stall effect generates higher circulatory forces during a short translation at high angle of attack than forces calculated under steady state conditions. During this phase the hand force coefficients are approximately twice as large as those of the forearm. The total force coefficients are highest for angles of attack between 40° and 60°. For the same angle of attack, the forces produced when the leading edge is the thumb side are slightly greater than those produced when the leading edge is the little finger side.

Patient characteristics, interventions and outcomes of 1151 rapid response team activations in a tertiary hospital: a prospective study. Intern Med J 2017; 46:1398-1406. [PMID: 27600063 DOI: 10.1111/imj.13248] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2016] [Revised: 08/23/2016] [Accepted: 08/30/2016] [Indexed: 11/30/2022]
Abstract
BACKGROUND The characteristics of mature contemporary rapid response systems are unclear. AIM To determine the patient characteristics, processes and outcomes, both in-hospital and post-discharge, of a well-established rapid response system in a tertiary adult hospital. METHODS This is a prospective study of consecutive rapid response team (RRT) activations between 1 July and 25 November 2015. Variables included patient characteristics, timing, location and triggers of RRT activations, interventions undertaken, mortality and readmission status at 28 days post-discharge. RESULTS A total of 1151 RRT activations was analysed (69.1 per 1000 admissions), involving 800 patients, of whom 81.5% were emergency admissions. A total of 351 (30.5%) activations comprised repeat activations for the same patient. Most activations (723; 62.8%) occurred out of hours, and 495 (43%) occurred within 48 h of admission. Hypotension, decreased level of consciousness and oxygen desaturation were the most common triggers. Advanced life support was undertaken in less than 7%; 198 (17.2%) responses led to transfer to higher-level care units. Acute resuscitation plans were noted for only 29.1% of RRT activations, with 80.3% stipulating supportive care only. A total of 103 (12.6%) patients died in hospital, equalling 14 deaths per 100 RRT activations. At 28 days, 150 (18.8%) patients had died, significantly more among those with multiple versus single RRT activations (24.9 vs 16.6%; odds ratio 1.66, 95% confidence interval 1.31-2.44; P = 0.013). CONCLUSION Relatively few RRT activations are associated with acute resuscitation plans, and most interventions during RRT responses are low level. The high rate of post-RRT deaths and transfers to higher-level care units calls for the prospective identification of such patients in targeting appropriate care.
