RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Due to the multifactorial nature of falls in the elderly population, it is difficult to determine causal relationships for risk factors for falls. In some cases, other risk factors may play a role. For example, the association between poor nutrition status and falls has not been studied extensively. The association of commonly demonstrated nutritional deficiencies in the elderly with factors such as balance, gait, and mobility may lead to new insights into causes of falls in the elderly not previously established. In this article, we review how malnutrition can be a risk factor for falls, how falls can induce malnutrition, and the possible relationship between mobility and nutrition in the elderly.

RESUMO

The effects of three strength development methods (during 6 weeks) were assessed on the body composition in 32 women, 62 to 75 years old and randomised in 3 groups. The first group (SC) has climbed and come down 300 stairs per session. The second group (ES) followed an electrostimulation programme on quadriceps muscles. The third group (SC+ES) has combined the stairs climbing with electrostimulation. Body composition and bone mineral density (BMD) was assessed using Absorptiometry machine before and after the programmes. None of the programmes has increased significantly BMD. Nevertheless, the SC+ES group BMD enhanced more on the trochanter (p<0,05) and the two legs (p<0,05) than the SC and ES groups BMD (interaction group/time). The combined activity (SC+ES) would deserve to be tested on a longer period.

RESUMO

BACKGROUND: Physical activity delays loss of autonomy in the elderly. In patients with Alzheimer disease (AD), physical activity could be a useful strategy in therapeutic management by delaying loss of functional independence and the usual complications of the disease. OBJECTIVE: To determine, using standardized tools, the effects on autonomy (ADL, IADL), cognitive function (MMS), nutritional status (MNA), behavioral problems (NPI) and risk of falls (Tinetti test) of a physical exercise program in patients with AD. DESIGN: Twenty-three subjects (13 men and 10 women, aged 71-92 years, mean 78 years) with AD (mean MMS 16, range 1-23) carried out for a mean of 7 weeks (5-12 weeks) a program of endurance exercise (walking, exercise bicycle) adapted to their individual capacities. Standardized gerontological evaluation was performed before and after the study. RESULTS: No significant change in autonomy (ADL, IADL) was observed. There was an improvement in the MNA (p<0.001) and the MMS (p<0.001). Risk of falls (p<0.01) and behavioral problems (p<0.05) decreased. These results were obtained without increasing family workload. CONCLUSION: We suggest that physical activity is a therapeutic option which can reduce nutritional and behavioral complications and risk of falls in subjects with AD.

RESUMO

The effects of a walking training programme were assesed on 10 healthy, active men aged 63-69 years. Serum lipids, pulse and blood pressure, maximum oxygen consumption (VO2 max) and anthropometric parameters, were measured before and after this programme. There was a significant fall in LDL (p<0.02) and mean diastolic BP (p<0.005). In spite of the subjects's initial good level of fitness there was still an 8% rise in the mean VO2 max of the group. There was also a significant loss of body fat (P<0.01). These positive physiological effects suggest that brisk walking can be considered as a a useful activity for improving the fitness and general health in this age-range.

RESUMO

AIM: The present study aimed to compare the effects of 3 strength development methods on muscular mass and muscular strength in healthy ageing women. METHODS: Thirty-two healthy women, 62 to 75 years old were randomised into 3 groups. The 3 groups performed 4 sessions a week of strength development for 6 weeks. The 1(st) group (SC) climbed up and down 300 stairs per session. The 2(nd) group (ES) followed an electrostimulation programme on the quadriceps muscles. The 3(rd) group (SC+ES) combined stair climbing with electrostimulation. Before and after the 3 programmes, the muscular mass of the leg was assessed using a biphotonic absorptiometry machine. Isometric (angle 20 degrees and 100 degrees ) and isokinetic (60 degrees /s and 240 degrees /s) knee extension torque was measured using an isokinetic dynamometer. RESULTS: None of the programmes changed the muscular mass. All 3 groups increased isometric (angle 20 degrees, p<0.001; angle 100 degrees, p<0.003) and isokinetic (60 degrees /s, p<0.0001; 240 degrees /s, p<0.0001) knee extension torque. None of the programmes appeared more efficient than the others for muscular mass or muscular strength. CONCLUSION: Six weeks of activity (SC, ES or SC+ES) improved the isometric and dynamic muscular strength in ageing healthy women. However, this period was too short to change the muscular mass. None of the activities presented a real advantage over the others in ageing women.

RESUMO

INTRODUCTION: Elderly people can be subdivided into three groups: healthy elderly persons (65-70% of the population), elderly subjects with diseases (about 5%) and frail old people. Frailty represents "age-related physiologic vulnerability resulting from impaired homeotasic stock and a reduced capacity of the organism to withstand stress". It could lead elderly subjects to pathological, barely reversible, ageing. CURRENT KNOWLEDGE AND KEY POINTS: One of the main objective of geriatricians is to develop useful screening tools to identify people at high risk, thus allowing them to benefit from preventive interventions as early as possible. It has been suggested that the decline in homeostatic stock involves numerous physiological systems. Those at the core of frailty would be neuromuscular changes resulting in sarcopenia, neuroendocrine dysregulation, and immune disorders. A recent study has shown that increased levels of interleukin 6 is a risk factor for frailty. FUTURE PROSPECTS AND PROJECTS: Work in progress aimed at identification of at-risk patients should: lead to early detection; draw attention on underestimated fields such as the nutritional status, sarcopenia, or gait disorders; promote the development of the standardized gerontological evaluation in order to identify the different components of frailty; and promote the development of non-pharmacological programmes including physical training, nutritional managing, and optimal social life.

RESUMO

Recommendations for dietary intake in elderly persons must account for wide interindividual variation. We propose different recommendations for: generally self sufficient elderly persons in good health. The recommended dietary intakes are very similar to those for adults, with a few exceptions (reduced calorie intake, the importance of protein and certain vitamins or minerals: vitamins B6, D, C, calcium, zinc ...); patients with an intercurrent disease or an event causing a loss of appetite and a reduction in dietary intake. Recommendations for these subjects should aim at correcting or preventing deficiencies by the use of supplementary and complementary nutritional products; subjects in a state of protein-calorie malnutrition. Recommended dietary intake should take into account the effect of malnutrition on the digestive functions of the pancreas and the intestine in the elderly. Such recommendations must be based on the findings of numerous studies now being carried out and of which we report here the first results.
