Metabolic syndrome and the phenotype of multiple sclerosis.

BACKGROUND: Comorbidities, particularly vascular comorbidities, have been shown to exacerbate the progression of disability in multiple sclerosis (MS). Metabolic syndrome (MetS) is a cluster of conditions including abdominal obesity, insulin resistance, atherogenic dyslipidemia, and vascular dysfunction, which contribute to vascular morbidity and chronic inflammation. OBJECTIVE: To describe the characteristics of MetS in a cohort of MS patients and evaluate its relationship with the MS phenotype. METHODS: A monocentric cohort study was conducted on MS patients, collecting demographic, clinical, radiological, and therapeutic data, as well as metabolic data including waist circumference, blood pressure, serum triglycerides, high-density lipoprotein cholesterol, and fasting blood glucose. RESULTS: Among the 84 patients included in the study, 27% were diagnosed with MetS. MetS was found to be associated with secondary progressive MS (SPMS). Patients with SPMS had a higher prevalence of MetS compared to those with relapsing-remitting MS (RRMS), even after adjusting for disease duration. While MetS was associated with Expanded Disability Status Scale (EDSS) progression in the 3-year period according to univariate analysis, it did not show a significant association with disease activity. CONCLUSION: This study provides evidence supporting the connection between MetS and the progression of disability in MS, independent of disease relapse activity.

Atrial fibrillation detection with long-term continuous Holter ECG recording in patients with high cardiovascular risk and clinical palpitations: the prospective after study.

AIM: New technologic tools for continuous ECG monitoring have been developed to detect and treat atrial fibrillation (AF) in specific populations with high cardiovascular risk. We evaluated the prevalence and the management of AF diagnosed in patients with high cardiovascular risk and non-documented clinical palpitation undergoing systematic 14-day continuous ECG-Holter monitoring. METHODS: Patients were prospectively enrolled from December 2019 to December 2021 in this multicentre study, sponsored by the French National College of Cardiology. Patients met the following criteria: CHA2DS2VASc score ≥ 2 in males and ≥ 3 in females and clinical palpitations without previously documented arrhythmia. Enrolled patients underwent a continuous 14-day Holter-ECG monitoring for arrhythmia detection. RESULTS: Among the 336 included patients, 39% were male, 75% were greater than 65 years of age and 46.5% had suffered a prior stroke. AF was detected in 14% of patients, among which 23.4% were detected in the first 24 h of monitoring. Finally, age ≥ 65 years (p = 0.037) was significantly associated with AF, as well as male gender (p = 0.023) and a lower rate of antiplatelet therapy (p = 0.018). Patients with diagnosed AF had a prescription of anticoagulation therapy in 90%. Antiarrhythmic drugs were administered in 90% of AF patients and 13% underwent AF ablation. CONCLUSIONS: The systematic AF screening of patients with palpitations and high cardiovascular risk resulted in a diagnostic yield of AF in 14% of the population with a 14-day continuous ECG-Holter monitor. This strategy resulted in the prescription of anticoagulation and antiarrhythmic therapy in 90% of the AF detected population.

[Radiation induced brachial plexopathy: Diagnosis, risk factors, principles of care]. / La plexite radique : épidémiologie, diagnostic, facteurs de risque et prise en charge.

Radiation plexitis, also known as radiation-induced brachial neuropathy is a rare toxicity following axillary, breast, cervical or thoracic radiotherapy, first described in 1966 by Stoll and Andrew. Although improvements in radiotherapy techniques have greatly reduced its risk over the past seventy years, its severe form remains a dreaded complication that is difficult to manage in patients with increased life expectancy. This article summarizes the epidemiological elements, risk factors, diagnostic methods, doses and constraints to be respected in radiotherapy and the treatment strategies of radiation plexitis.

Using a stacker crane for sterile storage in the operating theatre: initial environmental microbiological qualification.

BACKGROUND: Adequate storage of sterile surgical devices must prevent contamination and the introduction of microbial contaminants inside the operating room. For functional and economic purposes, stacker cranes (STCs) could replace the traditional sterile storage room (TSSR). STCs are large, multi-stage, computer-assisted systems used to automatically store and retrieve loads from defined locations. However, their microbiological performance has not been evaluated. AIM: As part of the opening of a new building that included an operating theatre, we qualified a new STC and compared its microbiological control performance to that of the previous TSSR. METHODS: From December 2020 to March 2021, 590 environmental specimens (air, N = 56; surfaces, N = 534) were collected and interpreted according to the NF S90-351 French Association for Standardization standards. FINDINGS: Thorough surface disinfection was not sufficient for controlling microbial contamination in the STC. Thus, the initial qualification testing was conducted following an aggressive aerial chemical decontamination of the STC. Despite the lack of a HEPA filtered air system, the overall non-conformity rates were lower in the STC than in the TSSR (8.3% vs 21.4%, P=0.33 for air, respectively, and 9.7% vs 41.7% P<0.001 for surfaces). The air-controlled barrier in front of the loading zone appeared to be sufficient to prevent bacterial contamination. The presence of fungi must be carefully monitored. CONCLUSION: This is the first study supporting the contribution of STCs in saving space and improving the maintenance of sterile surgical device storage and availability under acceptable environmental conditions. Further studies are needed to assess the long-term microbiological contamination inside the STC.

Tuberculosis in sickle cell disease patients.

OBJECTIVE: Tuberculosis (TB) disease has rarely been reported in patients with sickle cell disease, but it is associated with an increased risk of bacterial infections. In France, sickle cell disease is frequent in populations with the highest prevalence of TB disease. We aimed to highlight clinical aspects of TB disease in patients with sickle cell disease. PATIENTS AND METHODS: Over a 10-year period, we retrospectively included all adults with sickle cell disease who had a positive culture for Mycobacterium tuberculosis managed in the adult sickle cell center of Henri-Mondor hospital. Sickle cell patients with TB disease were matched for comparison to adults without hemoglobinopathy and with documented TB disease in a 1:2 ratio. Logistic regression mixed models were performed. RESULTS: Twelve patients with sickle cell disease and documented TB disease (median age: 29years; IQR [25-34]) were compared to 24 non-sickle cell patients (median age: 33years; IQR [27.5-38.5]). Baseline characteristics were similar between groups except for sickle cell disease. Ten of the 12 patients with sickle cell disease had pulmonary TB. TB disease characteristics were similar between sickle cell and non-sickle cell patients although sickle cell patients had fewer positive sputum smears for acid-fast bacilli (P=0.003) and fewer lung cavitations (P=0.03). CONCLUSIONS: TB disease in sickle cell patients was globally similar to non-sickle cell patients, even though less infectious. Regular follow-up in specialized centers might allow for earlier TB disease diagnosis in sickle cell patients.

Framework Implementation of the INSPIRE ICOPE-CARE Program in Collaboration with the World Health Organization (WHO) in the Occitania Region.

INTRODUCTION: Limiting the number of dependent older people in coming years will be a major economic and human challenge. In response, the World Health Organization (WHO) has developed the «Integrated Care for Older People (ICOPE)¼ approach. The aim of the ICOPE program is to enable as many people as possible to age in good health. To reach this objective, the WHO proposes to follow the trajectory of an individual's intrinsic capacity, which is the composite of all their physical and mental capacities and comprised of multiple domains including mobility, cognition, vitality / nutrition, psychological state, vision, hearing. OBJECTIVE: The main objective of the INSPIRE ICOPE-CARE program is to implement, in clinical practice at a large scale, the WHO ICOPE program in the Occitania region, in France, to promote healthy aging and maintain the autonomy of seniors using digital medicine. METHOD: The target population is independent seniors aged 60 years and over. To follow this population, the 6 domains of intrinsic capacity are systematically monitored with pre-established tools proposed by WHO especially STEP 1 which has been adapted in digital form to make remote and large-scale monitoring possible. Two tools were developed: the ICOPE MONITOR, an application, and the BOTFRAIL, a conversational robot. Both are connected to the Gerontopole frailty database. STEP 1 is performed every 4-6 months by professionals or seniors themselves. If a deterioration in one or more domains of intrinsic capacity is identified, an alert is generated by an algorithm which allows health professionals to quickly intervene. The operational implementation of the INSPIRE ICOPE-CARE program in Occitania is done by the network of Territorial Teams of Aging and Prevention of Dependency (ETVPD) which have more than 2,200 members composed of professionals in the medical, medico-social and social sectors. Targeted actions have started to deploy the use of STEP 1 by healthcare professionals (physicians, nurses, pharmacists,…) or different institutions like French National old age insurance fund (CNAV), complementary pension funds (CEDIP), Departmental Council of Haute Garonne, etc. Perspective: The INSPIRE ICOPE-CARE program draws significantly on numeric tools, e-health and digital medicine to facilitate communication and coordination between professionals and seniors. It seeks to screen and monitor 200,000 older people in Occitania region within 3 to 5 years and promote preventive actions. The French Presidential Plan Grand Age aims to largely implement the WHO ICOPE program in France following the experience of the INSPIRE ICOPE-CARE program in Occitania.

How to Manage Frail Older Adults in the Community? Proposal of a Health Promotion Program Experienced in a City of 16,638 Inhabitants in France.

BACKGROUND: Health promotion programs could prevent and delay frailty and functional decline. However, in practice, the planning and establishment of such a program is a challenge for health care providers. We report an experimental model of screening and management for frail elderly conducted in Cugnaux, city of 16,638 inhabitants in France, by the Toulouse Gerontopole and the social care service of the Cugnaux City Hall. METHODS: A frailty screening self-administered questionnaire (FiND questionnaire) was sent to community-dwelling residents of 70 years old and over of Cugnaux. The completed questionnaires were analyzed and the subjects were classed into three groups: robust, frail, mobility disability, based on their score. Frail subjects and those with mobility disability invited to undergo a frailty assessment in the premises of the town hall realized by a nurse in order to identify the causes of their frailty and propose them a personalized intervention plan (PIP). RESULTS: The FiND questionnaire was sent to the residents of Cugnaux of 70 years old and over (n=2,003). After two mailings, 860 (42.9%) completed questionnaires were received. Mean age of the responders was 79.0 ± 6.2 years and 59.6% women (n= 511). According to the questionnaires analysis, 393 (45.7%) were robust, 212 (24.6%) frail, 240 (27.9%) had a mobility disability and 15 (1.7%) could not be classified due to missing data. 589 (68.5%) subjects accepted to be contacted by the Gerontopole nurse. The assessment by the nurse was proposed to frail subjects and those with mobility disability (n=313). Until 31 December 2016, 136 patients have been evaluated. The mean age was 80.1±5.4 and most patients were women (69.9%). The mean ADL score was 5.8±0.5 and the IADL showed a mean score of 6.9±1.7. According to Fried definition of frailty, 76 patients (55.9%) were pre-frail, and 35 (25.7%) frail. Concerning the frailty domains identified, 75 patients (55.1%) showed the alteration of physical performance, 70 (51.5%) thymic disorders and 46 (33.8%) sensory disorders. Preventive interventions proposed in the PIP were mostly physical interventions (86.8%, n=118) followed by cognitive (61.8%, n=84) and nutritional (39.7%, n=54) interventions. DISCUSSION: This project shows the feasibility to implement a care model in the community. It permitted a large identification of frail elderly people in the city population, insuring their assessment and clinical follow up to maintain their capacities and referring them to social services.

Anterior pituitary cell networks.

Both endocrine and non-endocrine cells of the pituitary gland are organized into structural and functional networks which are formed during embryonic development but which may be modified throughout life. Structural mapping of the various endocrine cell types has highlighted the existence of distinct network motifs and relationships with the vasculature which may relate to temporal differences in their output. Functional characterization of the network activity of growth hormone and prolactin cells has revealed a role for cell organization in gene regulation, the plasticity of pituitary hormone output and remarkably the ability to memorize altered demand. As such, the description of these endocrine cell networks alters the concept of the pituitary from a gland which simply responds to external regulation to that of an oscillator which may memorize information and constantly adapt its coordinated networks' responses to the flow of hypothalamic inputs.

Reducing "iatrogenic disability" in the hospitalized frail elderly.

BACKGROUND: Hospitalization is the first cause of functional decline in the elderly: 30 to 60% of elderly patients lose some independence in basic activities of daily living (ADL) during a stay in hospital. This loss of independence results from the acute condition that led to admission, but is also related to the mode of management. OBJECTIVE: This paper is a review of the literature on functional decline in elderly hospitalized patients. It is the first stage in a project aiming to prevent dependence that is induced during the course of care. METHODS: During a 2-day workshop in Monaco, a task force of 20 international experts discussed and defined the concept of "iatrogenic disability". RESULTS: 1- "Iatrogenic disability" was defined by the task force as the avoidable dependence which often occurs during the course of care. It involves three components that interact and have a cumulative effect: a) the patient's pre-existing frailty, b) the severity of the disorder that led to the patient's admission, and lastly c) the hospital structure and the process of care. 2- The prevention of "iatrogenic disability" involves successive stages. - becoming aware that hospitalization may induce dependence. Epidemiological studies have identified at-risk populations by the use of composite scores (HARP, ISAR, SHERPA, COMPRI, etc). - considering that functional decline is not a fatality. Quality references have already been defined. Interventions to prevent dependence in targeted populations have been set up: simple geriatric consultation teams, single-factor interventions (aimed for example at mobility, delirium, iatrogenic disorders) or multidomain interventions (such as GEM and ACE units, HELP, Fast Track, NICHE). These interventions are essentially centered on the patient's frailty and have limited results, as they take little account of the way the institution functions, which is not aimed at prevention of functional decline. The process of care reveals shortcomings: lack of geriatric knowledge, inadequate evaluation and management of functional status. The group suggests that interventions must not only identify at-risk patients so that they may benefit from specialized management, but they must also target the hospital structure and the process of care. This requires a graded "quality approach" and rethinking of the organization of the hospital around the elderly person.

[Non-invasive diagnosis of peritoneal tuberculosis]. / Diagnostic non invasif d'une tuberculose péritonéale.

Tuberculous peritonitis was suspected in a 33-year-old man, without significant past medical history or risk factor for tuberculosis, who presented with constitutional manifestations including fatigue and weight loss, fever for several weeks and inflammatory ascites. Echo-guided percutaneous biopsy of the thickened omentum showed numerous epithelioid granulomas, avoiding laparoscopic peritoneal biopsies. Recovery was uneventful under antituberculous treatment.

[Soft tissue characterization of the female pelvis with MRI]. / Caractérisation tissulaire IRM du pelvis féminin.

MRI allows optimal characterization of normal and pathological soft tissues of the female pelvis through the use of standard morphological T1W and T2W sequences, fat-suppression techniques and perfusion and diffusion weighted sequences.

Effects of a semiochemical on feed conversion index and related indicators on fast-growing broilers housed during forty-two days.

Consequences of stress in poultry may be assessed through a wide range of parameters. A semiochemical named mother hen uropygial secretion analogue (MHUSA) is known to decrease stress in broilers. Because stress influences their feeding behavior, this trial has been built so as to test the influence of MHUSA on feed conversion index and related indicators. Two hundred forty chicks were placed into 24 similar crates (10 chicks per crate) at 1 d of age. After 35 d, chickens under MHUSA presented similar feed conversion index compared with control. A treatment effect was observed on both heterophil:lymphocyte ratio and corticosterone (MHUSA

[Imaging in pelvic inflammatory disease]. / Imagerie de l'infection pelvienne.

This is a review of evolutive aspects in pelvic inflammatory disease (salpingitis, endometritis, pyosalpinx, tubo ovarian abscess) assessed by different imaging modalities (Ultrasound, CT, MRI and hysterosalpingography).

Influence of a preen gland secretion on growth and meat quality of heavy broilers.

Preen gland secretions were obtained from several hens that were rearing their chicks and the content of these secretions was analysed. From these results, a synthetic analogue of the secretions was created (given the title Mother Hen Uropygial Secretion Analogue, or MHUSA, in this study). According to a blinded, controlled experimental design, heavy broilers (strain SASSO T56N) were reared from 1 day of age in an environment treated with either MHUSA or control. At 80 days the birds were slaughtered. Post mortemcarcass weight, abdominal fat and fillet weights were then measured. Colour, pH and yield were also measured as indicators of meat quality. Broilers exposed to MHUSA had both higher carcass weights and higher fillet weights compared with control-treated birds (P < 0.05). Abdominal fat, pH, water loss and colorimetry results were similar between the treatment groups at all time points (24 h and 6 days post mortem) and also after a cooking procedure. The meat from the MHUSA birds was less yellow compared with control. It is concluded that constant exposure to MHUSA from rearing until slaughter improves growth rate in broilers without significantly affecting meat quality.

Ligamentoplasty of the forearm interosseous membrane using the semitendinosus tendon: anatomical study and surgical procedure.

Total longitudinal disruptions of the interosseous membrane can allow proximal radius migration and are seen in Essex-Lopresti lesions. We propose an original technique of ligamentoplasty using the semitendinosus tendon. The graft corresponds to the forearm rotation axis for an optimized isometry and longitudinal stabilization. Our ligamentoplasty technique was performed on ten fresh frozen right forearms. We successively assessed the innocuousness, efficiency and resistance of the ligamentoplasty. The ligamentoplasty induced neither passive limitation of pronation-supination nor neurovascular lesions. It prevented from radius proximal migration. The mean load to failure was 28 kg at both ulnar and radial sides of the graft. Our technique is original for the type and position of the graft. It seems safe, efficient and resistant enough for in vivo procedures. This technique decreases longitudinal loads on the radius. It should be indicated in patients with Essex-Lopresti syndrome, in association with radial head internal fixation or arthroplasty.

Comparison of the efficacy of a synthetic dog-appeasing pheromone with clomipramine for the treatment of separation-related disorders in dogs.

Sixty-seven dogs that showed signs of distress when separated from their owners (destructiveness, excessive vocalisation and house soiling) and hyperattachment were used in a randomised, blind trial to assess the potential value of a dog-appeasing pheromone in reducing the unacceptable behaviours. For ethical reasons, there was no placebo group and the effects of the pheromone were compared with the effects of clomipramine which is regularly used to treat this type of problem. The undesirable behaviours decreased in both groups, but the overall assessment by the owners indicated that there was no significant difference between the two treatments, although there were fewer undesirable events in the dogs treated with the pheromone, and the administration of the pheromone appeared to be more convenient.

[Is electrical stimulation with voluntary muscle contraction of physiologic interest in aging women?]. / L'électrostimulation surimposée à la contraction musculaire volontaire présente-t-elle un intérêt physiologique chez les sujets âgés?

OBJECTIVE: To analyze the physiological effects of electrical stimulation with voluntary muscle contraction exercise in postmenopausal women. MATERIALS AND METHODS: Thirty-two females aged 62 to 75 years were randomly assigned to three groups to perform four activity sessions for six weeks: group ME (N =11) climbed up and down stairs, group ES (N =11) practised electrostimulation, and group ME + ES (N = 10) undertook both activities. Physiological adaptations of body composition (lean and fat masses and bone mineral density), muscular strength (isometric and dynamic), vertical jump and posturokinetic activities (balance and gait) were analysed. RESULTS: For the three groups, the isometric strength at angle 100 degrees (average increase right and left legs, ME: 19 N.m; ES: 4.5 N.m; ME + ES: 11.5 N.m), the dynamic strength at speed 60 degrees.s(-1) (average increase right and left leg, ME: 15 N.m; ES: 14 N.m; ME+ES: 18.5 N.m) and the vertical jump (ME: 23 mm; ES: 16 mm; ME + ES: 34 mm) increased contrary in the body composition and posturokinetic activities. Nevertheless, the group ME + ES adapted differently on some parameters of bone mineral density (P < 0.05) and dynamic strength (P < 0.01) in relation to the groups ES and ME. CONCLUSION: Electrostimulation with voluntary muscle contraction exercise could induce different physiologic adaptations compared with electrostimulation or voluntary muscle contraction exercise alone.
