RESUMEN
INTRODUCTION: The second COPD Biennial organized by the COPD working group of the French Society of Respiratory Diseases took place in Paris (Cochin) on 13th December 2023. STATE OF THE ART: Major trends in 2023 were discussed; they encompassed concepts, definitions, biologics, care pathways, pulmonary rehabilitation and complex situations entailed by respiratory infections, cardiovascular comorbidities and pulmonary hypertension, and modalities of oxygen therapy and ventilation. PERSPECTIVES: The different talks underlined major changes in COPD including the concepts of pre-COPD, etiotypes, health trajectories and new definitions of exacerbation. Recent results in biologics for COPD open the door to new pharmacological options. Assessment of current care pathways in France highlighted some causes for concern. For example, pulmonary rehabilitation is a key but insufficiently practiced element. Respiratory infections require careful assessment and treatments. Diagnosis and treatment of cardiovascular comorbidities and pulmonary hypertension are of paramount importance. As of late, oxygen therapy and ventilation modalities have evolved, and are beginning to afford more personalized options. CONCLUSIONS: As regards COPD, a personalized approach is crucial, placing the patient at the center of the care pathway and facilitating coordination between healthcare providers.

Sarcopenia is a pathology resulting from a progressive and severe loss of muscle mass, strength, and function in the course of aging, which has deleterious consequences on quality of life. Among the most widespread studies on the issue are those focused on the effect of different types of physical exercise on patients with sarcopenia. This randomized controlled study aimed to compare the effects of a whole-body vibration exercise (WBV) session on the inflammatory parameters of non-sarcopenic (NSG, n=22) and sarcopenic elderly (SG, n=22). NSG and SG participants were randomly divided into two protocols: intervention (squat with WBV) and control (squat without WBV). After a one-week washout period, participants switched protocols, so that everyone performed both protocols. Body composition was assessed by dual-energy radiological absorptiometry (DXA) and function through the six-minute walk test (6MWD) and Short Physical Performance Battery (SPPB). Plasma soluble tumor necrosis factor receptors (sTNFR) were determined by enzyme-linked immunosorbent assay (ELISA) and measured before and immediately after each protocol. After exercise with WBV, there was an increase in sTNFR2 levels in the NSG (P<0.01; d=-0.69 (-1.30; -0.08) and SG (P<0.01, d=-0.95 (-1.57; -0.32) groups. In conclusion, an acute session of WBV influenced sTNFr2 levels, with sarcopenic individuals showing a greater effect. This suggested that WBV had a more pronounced impact on sTNFr2 in those with loss of muscle strength and/or physical performance. Additionally, WBV is gaining recognition as an efficient strategy for those with persistent health issues.

RESUMEN
In myotonic mystrophy type 1 (DM1), combining respiratory symptom screening and respiratory function testing, is crucial to identify the appropriate time for ventilatory support initiation. Dyspnea has been little investigated in DM1. To provide a multidimensional description of dyspnea, questionnaires assessing dyspnea were administered to 34 consecutive adult patients with DM1 (median (25th-75th centile) age of 36 (28-49), Vital Capacity (VC) of 74 (64-87)% of predicted value). Dyspnea scores were low whatever the questionnaire used: Multidimensional Dyspnea Profile score of 2(0-4.7)/50 for dyspnea sensory descriptor and of 0 (0-4.7)/60 for the emotional descriptor, Visual Analogue Scale score of 0 (0-0)/10 in sitting and supine position and Borg score after six-minute walk test (6MWT) of 2.2 (1.8-4.2)/10. Eleven patients (32%) reported disabling dyspnea in daily living (modified Medical Research Council (mMRC) score ≥ 2). In comparison with patients with mMRC score < 2, patients with mMRC score ≥ 2 had a more severe motor handicap (Muscular Impairment Rating score of 4.0 (4.0-4.0) vs 3.0 (2.0-3.5), p<0.01), a lower 6MWT distance (373 (260-424) vs 436 (346-499)m, p = 0.03) and a lower VC (64 (48-74)% vs 75 (69-89)%, p = 0.02). These data suggest that the mMRC scale might be an easy-to-use and useful tool to assess dyspnea in daily living in DM1 patients. However, the interest of integrating the mMRC dyspnea scale in clinical practice to guide therapeutic management of DM1 patients remains to be assessed in further studies.

The hyperventilation syndrome is a complex entity whose management is poorly codified. We report a synthesis about the management of adult patients diagnosed with hyperventilation syndrome. A systematic literature review has identified fifteen articles dealing, among them three studies about drug treatment and the others about non-pharmacological approaches. Among the last ones, a re-educational approach based on abdominal ventilation and regulation of the ventilatory rate seems and an educative approach seems to be the most effective. Methodological biases did not permit a conclusion on the efficacy of these treatments. Practically, teaching abdominal ventilation and respiratory rate regulation, associated with a personalized therapeutic education, seems to be a pertinent management approach. Other clinical studies should explore this issue.

The objective of this study was to determine the clinical characteristics of swallowing disorders in severe brain injury in the arousal phase after coma. Between December 1, 2013 and June 30, 2014, eleven patients with severe acquired brain injury who were admitted to rehabilitation center (Male 81.8 %; 40.7 ± 14.6 years) were included in the study. Evaluation of swallowing included a functional examination, clinical functional swallowing test, and naso-endoscopic swallowing test. All patients had swallowing disorders at admission. The first functional swallowing test showed oral (77.8 %) and pharyngeal (66.7 %) food bolus transport disorders; and alterations in airway protection mechanisms (80 %). Swallowing test under endoscopic control showed a disorder in swallowing coordination in 55.6 % of patients tested. Seven (63.6 %) patients resumed oral feeding within an average of 6 weeks after admission to rehabilitation center and 14 weeks after acquired brain injury. Six (85.7 %) of these seven patients continued to require modified solid and liquid textures. Swallowing disorders are a major concern in severe brain injury in the arousal phase. Early bedside assessment of swallowing is essential for detection of swallowing disorders to propose appropriate medical rehabilitation care to these patients in a state of altered consciousness.

OBJECTIVE: Physical therapy strategies have recently proved their efficacy in the field of Parkinson's disease management. The purpose of this paper was to access the efficacy and the limits of aerobic training and strength training included in physical rehabilitation programs and to define practical modalities. METHOD: A comprehensive search on Pubmed and Cochrane databases was made. RESULTS: Five literature revues and thirty one randomised trials have been selected. Exercise training improves aerobic capacities, muscle strength, walking, posture and balance parameters. Rehabilitation programs should begin as soon as possible, last several weeks and be repeated. They should include aerobic training on bicycle or treadmill and a muscle strengthening program. CONCLUSION: There is evidence that aerobic and strength training improve physical habilities of patients suffering from Parkinson's Disease. Rehabilitation programs should be discussed with the patient, taking in account his difficulties and his physical capacities. Two questions are debatable: exercise intensity and phase ON / phase OFF timing.

INTRODUCTION: Up until now, there has been little description of the test exercises carried out in patients with neuromuscular diseases. However, prescription of physical therapy by exercise requires rigorous individualized assessment of the patient's physical endurance parameters. OBJECTIVE: To describe exercise tolerance and external limitation factors in a sample group of adult patients suffering from neuromuscular diseases. MATERIALS AND METHODS: A descriptive retrospective study of exercise tests realized at the Reims university hospital for patients divided into three groups according to their pathologies: CMT hereditary neuropathies, muscular dystrophies, metabolic myopathies. RESULTS: Forty-four (44) tests were analyzed. Cessation was occasioned on 63.6% of the cases by muscular symptomatology, with no possibility of maintaining the cycling frequency in 29.5% of the overall population. Insufficient lung volume recruitment was involved in 61.4% of the patients, final oxygen pulse (VO2/heart rate) was 80% lower than the theoretical pulse in 50% of the patients, and there existed an early first ventilatory threshold in 54.5% of the cases. Peripheral deconditioning was highly severe in 18% of the population and significantly greater in the subjects suffering from dystrophies (VT1 at 31% of the maximum theoretical O2, P<0.001). DISCUSSION: The main limitation factor in exercise tests is peripheral. Ventilatory and cardiovascular limitations can nonetheless be added on; while they are absent when the patient is at rest, they are unmasked in effort situations. Exercise tests could be of great interest in screening and managing the relevant pathologies. Multicenter studies on homogeneous populations could facilitate definition of the procedures specific to exercise tests for patients suffuring from neuromuscular diseases.

Rehabilitation is a recommended first-line therapy for patients with peripheral arterial disease (PAD) and consists of supervised exercise training and therapeutic education. Proved benefits are significant: improve pain-free walking distance, functional status and quality of life; reduce cardiovascular risk factors and mortality. At least three sessions weekly are recommended during 3 months. Exercise conditioning (global training and lower limb resistance training) is tailored by the preliminary evaluation of walking ability (free walking test, treadmill tests, 6-min walk test) and of the cardiac tolerance (maximal effort tests). Then the exercise workload is progressively improved. The four main goals of therapeutic education are: smoking cessation, prolonged physical activity, Mediterranean diet and observing pharmacological therapies. The limited compliance of the patients with PAD is often an obstacle for educational needs. The chronic patients with important functional limitations and unchecked risk factors will be preferentially enrolled in such programs. When a revascularization is discussed, rehabilitation can serve as trial treatment. Despite its efficacy, rehabilitation is still underutilized in clinical practice and should be promoted.

Post-polio syndrome (PPS) refers to a clinical disorder affecting polio survivors with sequelae years after the initial polio attack. These patients report new musculoskeletal symptoms, loss of muscular strength or endurance. PPS patients are tired, in pain and experience new and unusual muscular deficits, on healthy muscles as well as deficient muscles initially affected by the Poliovirus. Once a clinical diagnosis is established, the therapeutic options can be discussed. Some pathophysiological mechanisms have been validated by research studies on PPS (inflammatory process in cerebrospinal fluid [CSF] and cytokines of the immune system). Several studies have been conducted to validate medications (pyridostigmine, immunoglobulin, coenzyme Q10) or physical exercises protocols. This article focuses on the relevance and efficacy that can be expected from these therapeutics. Very few studies reported some improvements. Medications combined to individual and supervised exercise training programs are promising therapeutic strategies for PPS patients care management.

Post-polio syndrome (PPS) is the commonly affected term to describe the symptoms that may develop many years after acute paralytic poliomyelitis. The etiology of PPS is still unclear. An overuse of enlarged motor units is suspected causing denervation again due to distal degeneration of axons. Metabolic and functional changes has been described in muscle fibers of partially denervated muscles. Nevertheless, submaximal aerobic training and low intensity muscular strengthening have shown positive effects on muscular strength and cardiorespiratory system in patients affected by PPS. Aquatic therapy has a positive impact on pain and muscle function. In patients with severe fatigue, it is recommended to adapt the daily exercise routine to their specific case.

Lipopolysaccharides from a number of mutants of Escherichia coli K-12 were investigated by means of chemical and serological methods. Inhibition of passive hemagglutination and inhibition of precipitation show that L-rhamnose is the immunodominant sugar in the lipopolysaccharide from wild-type E. coli K-12. The disaccharide rhamnosyl-KDO (where KDO is 3-deoxy-D-manno-octulosonic acid) was isolated and characterized after mild acid hydrolysis of the lipopolysaccharide. It is concluded that rhamnose is present in the innermost part of the core as a side-chain substituent on KDO. From crosses between an E. coli K-12 donor and E. coli O8, hybrids were obtained which contained either one or both of the donor rfa and rfb clusters. Serum absorption studies with lipopolysaccharides from these hybrids indicated that the histidine-linked rfb cluster is responsible for the presence of rhamnose in the K-12 core oligosaccharide. Using paper chromatography of 32P-labelled lipopolysaccharides we have found heterogeneous lipopolysaccharide in two strains as well as some differences between two wild-type strains. The latter difference is believed to be due to varying contents of KDO-linked ethanolamine phosphate. The overall results presented together with those described in the companion paper clearly show that the core oligosaccharide in E. coli K-12 has a structure different from the types previously described for other strains of E. coli (designed coli R1 to coli R4).
