Psychometric validation of the French Multidimensional Chronic Asthenia Scale (MCAS) in a sample of 621 patients with chronic fatigue.

BACKGROUND: Psychometric validation of the Multidimensional Chronic Asthenia Scale (MCAS) was conducted in order to provide an effective tool for assessing the health-related quality of life of French-speaking patients with chronic asthenia (CA). METHODS: Items resulting from the initial formulation of the self-reported MCAS (along with other materials) were completed by French-speaking volunteers with inactive or active inflammatory bowel disease (IBD-I vs. IBD-A) or chronic fatigue syndrome (CFS). Responses from 621 participants (180 patients with IBD-A, 172 with IBD-I, 269 with CFS) collected in a single online survey were divided into three subsamples to test the construct validity of the MCAS (Step 1, N = 240), to confirm its factorial structure (Step 2, N = 204) and to explore its convergent-discriminant validity with the Fatigue Symptoms Inventory (FSI) and revised Piper Fatigue Scale (r-PFS, Step 3, N = 177). RESULTS: Steps 1 and 2 showed that, as expected, MCAS has four dimensions: feeling of constraint (FoC), physical (PC), life (LC) and interpersonal consequences (IC), which are also related to the duration of CA (i.e., the longer it lasts, the more the dimensions are impacted). The results further showed that the MCAS is sensitive enough to capture between-group differences, with the CFS group being the most impaired, followed by IBD-A and IBD-I. While convergent-discriminant validity between the 4 factors of MCAS and FSI and r-PFS, respectively, was satisfactory overall, Step 3 also pointed to some limitations that call for future research (e.g., shared variances between the PC and IC dimensions of MCAS and behavioral dimension of r-PFS). CONCLUSION: Despite these limitations, the MCAS clearly constitutes a promising tool for measuring quantitative differences (i.e., severity/intensity) in CA associated with various diseases, but also, and importantly, the clinically important differences in domains of its expression (i.e., qualitative differences).

An 81-Year-Old Man Presenting with Asthenia and Anorexia After an Alcohol-Induced Hypoglycemic Coma and a Diagnosis of Central Adrenal Insufficiency: A Case Report.

BACKGROUND Alcohol abuse inhibits the ability of the liver to release glucose into the bloodstream, primarily by inhibiting gluconeogenesis, so chronic alcohol abusers exhibit hypoglycemia after drinking alcohol without eating; this is called alcohol-induced hypoglycemia. Central adrenal insufficiency (AI) is characterized by cortisol deficiency due to a lack of adrenocorticotropic hormone. It is challenging to diagnose central AI, as it usually presents with nonspecific symptoms, such as asthenia, anorexia, and a tendency toward hypoglycemia. Here, we report a rare case of central AI that presented with AI symptoms shortly after an alcohol-induced hypoglycemic coma. CASE REPORT An 81-year-old Japanese man who had been a moderate drinker for >40 years developed a hypoglycemic coma after consuming a large amount of sake (alcohol, 80 g) without eating. After the hypoglycemia was treated with a glucose infusion, he rapidly recovered consciousness. After stopping alcohol consumption and following a balanced diet, he had normal plasma glucose levels. However, 1 week later, he developed asthenia and anorexia. The endocrinological investigation results indicated central AI. He was started on oral hydrocortisone (15 mg/day), which relieved his AI symptoms. CONCLUSIONS Cases of central AI associated with alcohol-induced hypoglycemic attacks have been reported. Our patient developed AI symptoms following an alcohol-induced hypoglycemic attack. His alcohol-induced hypoglycemic attack likely occurred in combination with a developing cortisol deficiency. This case highlights the importance of considering central AI in chronic alcohol abusers presenting with nonspecific symptoms, including asthenia and anorexia, especially when patients have previously experienced alcohol-induced hypoglycemic attacks.

[Epidemiological, Clinical And Evolutionary Characteristics Of Autoimmune Dysthyroidism In The National University Center Hubert Koutoukou Maga (CNHU-HKM) Of Cotonou]. / Caracteristiques Epidemio-Cliniques Et Evolutives Des Dysthyroïdies Auto-Immunes Au Centre National Hospitalier Universitaire Hubert Koutougou Maga (CNHU-HKM) De Cotonou.

OBJECTIVE: To study the epidemiological, clinical and evolutionary characteristics of autoimmune dysthyroidism in the endocrinology-diabetes department of the CNHU-HKM. MATERIAL AND METHOD: This was a descriptive and analytical cross-sectional study of patients seen for thyroid pathology in the endocrinology diabetology department over a 10-year period. Patients with at least one abnormal TSH and positive anti-thyroid antibodies were included. RESULTS: Over the study period, we recorded 2883 consultants, 347 of them having thyroid diseases, including 69 cases of autoimmune dysthyroidism divided into 54 cases of Graves' disease and 15 cases of Hashimoto's disease. Autoimmune dysthyroidism represented 2.39% of consultations and 19.89% of thyroid disorders. Graves' disease and Hashimoto's disease accounted for 1.87% (54 cases) and 0.52% (15 cases) of consultations respectively. Autoimmune dysthyroidism was more frequent in the 30-40 and 40-50 age groups. The most frequent symptoms of Graves' disease were asthenia (94.4%), weight loss (87.0%) and tachycardia (85.2%). In Hashimoto's disease, the main symptoms were asthenia (86.66%), goiter (66.6%) and weight gain (60%). High initial R-TSH antibody levels and iatrogenic hypothyroidism were found to be factors associated with extended follow-up of Graves' disease beyond 18 months. CONCLUSION: Autoimmune dysthyroidism is a frequent condition, with Graves' disease predominating. Their evolution under therapy is influenced by clinical, biological and ultrasonographic factors.

OBJECTIF: Etudier les caractéristiques épidémio cliniques et évolutives des dysthyroïdies auto immunes dans le service d'endocrinologie diabétologie du CNHU-HKM. MATÉRIEL ET MÉTHODE D'ÉTUDE: Il s'agit d'une étude transversale descriptive et analytique ayant porté sur les patients reçus en consultation pour une pathologie thyroïdienne dans le service d'endocrinologie diabétologie sur une période de 10 ans. Ont été inclus les patients ayant au moins une TSH anormale et les anticorps anti thyroïdiens positifs. RÉSULTATS: Sur la période d'étude, nous avons enregistré 2883 consultants, 347 avaient une pathologie thyroïdienne, dont 69 cas de dysthyroïdie auto-immune répartis en 54 cas de maladie de Basedow et 15 cas de maladie de Hashimoto. Les dysthyroïdies auto immunes représentaient donc 2,39 % des consultations et 19,89% des thyroïdopathies. Les fréquences de la maladie de Basedow et de la maladie de Hashimoto étaient respectivement de 1,87% (54 cas) et 0,52% (15 cas) parmi les consultations. Les dysthyroïdies auto immunes étaient plus fréquentes dans les tranches d'âge de 30 à 40 et 40 à 50 ans. Les manifestations les plus fréquentes de la maladie de Basedow étaient l'asthénie (94,4%), l'amaigrissement (87,0%) et la tachycardie (85,2%) . Quant à la maladie de Hashimoto les principales manifestations étaient représentées par une asthénie (86,66%), un goitre (66,6%) et une prise de poids (60%). Le titre initial élevé des anticorps anti R-TSH, l'hypothyroïdie iatrogène ont été retrouvés comme des facteurs associés au suivi prolongé de la maladie de Basedow au-delà de 18 mois. CONCLUSION: Les dysthyroïdies auto-immunes sont des affections fréquentes dominées par la maladie de Basedow. Leur évolution sous traitement est influencée par des facteurs cliniques, biologiques et échographiques.

Association of Low Handgrip Strength with Chemotherapy Toxicity in Digestive Cancer Patients: A Comprehensive Observational Cohort Study (FIGHTDIGOTOX).

In the FIGHTDIGO study, digestive cancer patients with dynapenia experienced more chemotherapy-induced neurotoxicities. FIGHTDIGOTOX aimed to evaluate the relationship between pre-therapeutic handgrip strength (HGS) and chemotherapy-induced dose-limiting toxicity (DLT) or all-grade toxicity in digestive cancer patients. HGS measurement was performed with a Jamar dynamometer. Dynapenia was defined according to EWGSOP2 criteria (<27 kg (men); <16 kg (women)). DLT was defined as any toxicity leading to dose reduction, treatment delay, or permanent discontinuation. We also performed an exploratory analysis in patients below the included population's median HGS. A total of 244 patients were included. According to EWGSOP2 criteria, 23 patients had pre-therapeutic dynapenia (9.4%). With our exploratory median-based threshold (34 kg for men; 22 kg for women), 107 patients were dynapenic (43.8%). For each threshold, dynapenia was not an independent predictive factor of overall DLT and neurotoxicity. Dynapenic patients according to EWGSOP2 definition experienced more hand-foot syndrome (p = 0.007). Low HGS according to our exploratory threshold was associated with more all-grade asthenia (p = 0.014), anemia (p = 0.006), and asthenia with DLT (p = 0.029). Pre-therapeutic dynapenia was not a predictive factor for overall DLT and neurotoxicity in digestive cancer patients but could be a predictive factor of chemotherapy-induced anemia and asthenia. There is a need to better define the threshold of dynapenia in cancer patients.

[Efficacy of Mexidol in patients with chronic brain ischemia and cognitive impairment of different age groups (results of sub-analysis of the international multicenter, randomized, double-blind, placebo-controlled study of sequential therapy in patients with chronic brain ischemia MEMO)]. / Effektivnost' Meksidola u patsientov raznykh vozrastnykh grupp s khronicheskoi ishemiei golovnogo mozga s kognitivnymi narusheniyami (rezul'taty subanaliza mezhdunarodnogo mnogotsentrovogo randomizirovannogo dvoinogo slepogo platsebo-kontroliruemogo issledovaniya MEMO).

OBJECTIVE: To assess the efficacy of sequential therapy with Mexidol and Mexidol FORTE 250 in comparison with placebo in patients of different age groups with chronic brain ischemia. MATERIAL AND METHODS: The study is sub-analysis of data of the international multicenter, randomized, double-blind, placebo-controlled study of sequential therapy in patients with chronic brain ischemia (MEMO), which included 318 patients (25% men) in the age of 40-90 (median 60) years. All subjects were subdivided into 3 age subgroups: 40-60 years (n=163), 61-75 years (n=141) and 76-90 years (n=13). The primary efficacy endpoint was the dynamic of increase of total score by MoCA scale, i.e. the absolute value of difference by MoCA scale at the point of day 75 comparing to values before treatment. As secondary efficacy endpoints results of dynamic by following questionnaires and scales were used: digit symbol substitution test, the Health Survey SF-36, asthenia subjective assessment scale (MFI-20), Vane questionnaire, Beck anxiety scale, Tinetti scale. RESULTS: After 75 days of treatment positive dynamic was revealed in cognitive, emotional and motor impairment in patients of 40-60 and 61-75 age subgroups both in groups of Mexidol and placebo, but in group of Mexidol the changes were more prominent which is proved by significantly higher values of median of absolute difference of total score of studied parameters. CONCLUSION: The results of trial showed that in patients of different age-subgroups with chronic brain ischemia the improvement in cognitive, motor impairment and quality of life, as well as decrease in vegetative impairment, asthenia and anxiety are observed after 75 days of treatment both in Mexidol and placebo group, but in Mexidol group these changes are more prominent. The data obtained confirm the expediency of the use of sequential therapy with Mexidol and Mexidol FORTE 250 in patients of different age subgroups with chronic brain ischemia.

[Analysis of the correlation between neuroimaging markers of the brain damage and the severity of postural instability in patients with chronic cerebrovascular insufficiency (NEMAN open observational study)]. / Svyaz' neirovizualizatsionnykh markerov porazheniya golovnogo mozga i vyrazhennosti postural'noi neustoichivosti u patsientov s khronicheskoi ishemiei golovnogo mozga (rezul'taty otkrytogo nablyudatel'nogo issledovaniya NEMAN).

OBJECTIVE: To analyze the relationship between the severity of postural instability in patients with CCI (chronic cerebral ischemia) and brain changes according to MRI, as well as to evaluate the efficacy and safety of vinpocetine. MATERIAL AND METHODS: The study included 60 patients with CCI: 40 people with postural instability made up the main group and 20 people without balance disorders - the control group. The severity of manifestations of cerebrovascular pathology was assessed according to the protocol STRIVE. Severity of postural instability was assessed with the VAS, anxiety syndrome - Hamilton Anxiety Rating Scale, asthenia - Asthenic Condition Scale, daytime sleepiness - Epworth Sleepiness Scale, cognitive impairment - Montreal scale assessment of cognitive functions, the overall impression of treatment - Global Rating of Change Scale. RESULTS: The main group was associated with older age, more significant decrease in cognitive functions, urination disorders, anxiety syndrome and asthenia, changes according to MRI of the brain. CCI burden scale was significantly associated with VAS: ß=0.479, P=0.035, 95% CI 0.023-0.928. The presence of lacunae was the most significant marker for the development of severe imbalance: ß=0.482, p=0.041, 95% CI 0.022-0.925. A significant relationship was found between the total number of lacunae and VAS (r=0.509, p=0.021), as well as between the number of lacunae in the basal ganglia (r=0.793, p=0.019), especially the lenticular nuclei (r=0.498, p=0.036), and VAS. After 3 months of vinpocetine treatment, a significant improvement in statodynamic function was noted in the main group, moreover - absence of anxiety, normalization of daytime sleep, «weak¼ asthenia, increasement in the value of the MoCA scale. Most of the patients regarded the improvement from the therapy as «moderate¼ and «pronounced¼. CONCLUSIONS: The presence of lacunes in the basal ganglia is a most prominent neuroimaging marker of brain damage in patients with CCI and postural instability. The use of vinpocetine can significantly reduce the severity of imbalance, anxiety and asthenia, and normalize the circadian rhythm of sleep.

Long-term Efficacy and Safety of Rifampin in the Treatment of a Patient Carrying a CYP24A1 Loss-of-Function Variant.

BACKGROUND: Pharmacological therapy may be useful in the treatment of moderate to severe hypercalcemia in patients with infantile hypercalcemia-1 (HCINF1) due to pathogenic variants in the cytochrome P450 24 subfamily A member 1 (CYP24A1). Rifampin is an antituberculosis drug that is a potent inducer of cytochrome P450 3 subfamily A member 4, which is involved in an alternative catabolic pathway of vitamin D. The efficacy of rifampin in improving hypercalcemia was previously reported, but many questions remain on the long-term efficacy and safety. The aim of the study is to test the long-term efficacy and safety of rifampin in a patient with HCINF1. METHODS: We report clinical, biochemical, and imaging features of a 23-year-old man affected by HCINF1 with moderate hypercalcemia (12.9 mg/dL), symptomatic nephrolithiasis, nephrocalcinosis, and impaired kidney function [estimated glomerular filtration rate (eGFR) 60 mL/min/1.73 m2] treated with rifampin for an overall period of 24 months. Kidney, liver, and adrenal function were evaluated at every follow-up visit. RESULTS: In 2 months, rifampin induced a normalization of serum calcium (9.6 mg/dL) associated with an improvement of kidney function (eGFR 92 mL/min/1.73 m2) stable during the treatment. After 15 months, rifampin was temporally withdrawn because of asthenia, unrelated to impairment of adrenal function. After 3 months, the timing of drug administration was shifted from the morning to the evening, obtaining the remission of asthenia. At the end of follow-up, the nephrolithiasis disappeared and the nephrocalcinosis was stable. CONCLUSIONS: Rifampin could represent an effective choice to induce a stable reduction of calcium levels in patients with HCINF1, with a good safety profile.

Prevalence of Hoarseness and Its Association with Severity of Dysphagia in Patients with Sarcopenic Dysphagia.

OBJECTIVES: To investigate the prevalence of hoarseness and its association with the severity of dysphagia in patients with sarcopenic dysphagia. DESIGN: Cross-sectional study using the Japanese sarcopenic dysphagia database. SETTING: 19 hospitals including 9 acute care hospitals, 8 rehabilitation hospitals, 2 long-term care hospitals, and 1 home visit rehabilitation team. PARTICIPANTS: 287 patients with sarcopenic dysphagia, aged 20 years and older. MEASUREMENTS: Sarcopenic dysphagia was diagnosed using a reliable and validated diagnostic algorithm for the condition. The presence and characteristics of hoarseness classified as breathy, rough, asthenic, and strained were assessed. The prevalence of hoarseness and the relationship between hoarseness and Food Intake LEVEL Scale (FILS) were examined. Order logistic regression analysis adjusted for age, sex, naso-gastric tube, and handgrip strength was used to examine the relationship between hoarseness and FILS at baseline and at follow-up. RESULTS: The mean age was 83 ± 10 years. Seventy-four (26%) patients had hoarseness, while 32 (11%), 20 (7%), 22 (8%), and 0 (0%) patients had breathy, rough, asthenic, and strained hoarseness, respectively. Median FILS at the initial evaluation was 7 (interquartile range, 5-8). Hoarseness (ß=0.747, 95% confidence intervals= 0.229, 1.265, p=0.005), age, sex, naso-gastric tube, and handgrip strength were associated independently with baseline FILS, while hoarseness (ß=0.213, 95% confidence intervals= -0.324, 0.750, p=0.438) was not associated independently with the FILS at follow-up. CONCLUSIONS: Hoarseness was associated with the severity of dysphagia at baseline, however not a prognostic factor for sarcopenic dysphagia. Resistance training of swallowing and respiratory muscles and voice training as part of rehabilitation nutrition might be useful for treating sarcopenic dysphagia.

Lipoinjection for Unilateral Vocal Fold Paralysis Treatment: A Systematic Review and Meta-Analysis.

INTRODUCTION: Lipoinjection is one of the available treatments for unilateral vocal fold paralysis. OBJECTIVE: To evaluate lipoinjection predictability, and analyze the differences in safety and efficacy of the different techniques. STUDY DESIGN: Systematic review and meta-analysis. METHODS AND RESULTS: A systematic review on Medline, Cochrane, and Scopus databases included 49 articles analyzing the data of 1,166 patients, concerning technical details and voice parameters changes. Lipoinjection used a mean volume of 1.3 mL, 95% confidence interval (CI) (0.92, 1.69)-average overcorrection of 30%. Meta-analysis of pre- and postoperative voice parameters' means showed a significant improvement at 6 months of mean phonation time (preoperative: 5.12, 95% CI [4.48, 5.76]-6 months: 10.46, 95% CI [9.18, 11.75]), Jitter (preoperative: 2.71, 95% CI [2.08, 3.33])-6 months: 1.37, 95% CI [1.05, 1.70]), Shimmer (preoperative: 4.55, 95% CI [3.04, 6.07]-6 months: 2.57, 95% CI [1.69, 3.45]), grade (preoperative: 2.15, 95% CI [1.73, 2.57]-6 months: 0.12, 95% CI [0.97, 1.43]), breathiness (preoperative: 2.012, 95% CI [1.48, 2.55]-6 months: 0.99, 95% CI [0.58, 1.40]), and asthenia (preoperative: 1.90, 95% CI [1.33, 2.47]-6 months: 0.75, 95% CI [0.17, 1.33]) of GRBAS (Grade, Roughness, Breathiness, Asthenia and Strain), and Voice Handicap Index-30 (preoperative: 72.06, 95% CI [54.35, 89.76]-6 months: 26.24, 95% CI [19.58, 32.90]). Subgroup analysis by harvesting technique concluded in no statistically significant difference between them. Few complications were reported. Reintervention was only required for 86 patients. CONCLUSION: Lipoinjection seems a safe therapeutic option for unilateral vocal fold paralysis, with available data showing an efficacy lasting 6 months to 1 year. Laryngoscope, 132:1630-1640, 2022.

A 31-year-old woman, with signs of HIV infection (oral thrush, weight loss, asthenia) presented to our hospital with dyspnea and fever. A rapid HIV test yielded a positive result, and cryptococcal capsular antigen was detected in serum. In the mycological study of the clinical respiratory samples, yeasts compatible with Cryptococcus were observed under light microscope in a wet mount; structures compatible with Pneumocystis jirovecii were also observed in Giemsa stain. Treatment for both pathologies was prescribed but, unfortunately, the patient died 7 days after. The finding of two etiologic agents in the same clinical picture is rare but not exceptional, and it always must be considered in immunocompromised hosts

[Features of positive personality phenomena in patients with mild cognitive impairment and asthenic syndrome treated with recognan (citicoline)]. / Vliianie primeneniia preparata Rekognan (tsitikolin) na proiavleniia pozitivnykh lichnostnykh kachestv u patsientov s astenicheskim sindromom i legkimi kognitivnymi narusheniiami.

AIM: To assess the formation of positive personality phenomena in patients with mild cognitive impairment and asthenic syndrome during the treatment with recognan (citicoline). MATERIAL AND METHODS: Thirty-eight patients (17 men and 21 women), aged 18 to 45 years (mean age 27.8±12.1 years), with asthenic syndrome with mild cognitive impairment (ICD-10 F06.7) were examined. Patients were divided into two groups: 20 people in the main group and 18 people in the comparison group. The main group received recognan (orally, in solution, 100 mg in 1 ml) for 30 days, the daily dosage of the drug was 0.5 g (5 ml solution). The comparison group did not receive any medications. Adapted methods of positive personality psychology were used: the Fordyce Emotions Questionnaire, the Subjective Happiness Scale (SHS), the Adult Hope Scale (AHS), the Satisfaction with Life Scale (SWLS), M. Atkinson's Scale of Emotional Maturity, the projective technique 'Map of experiences'. The follow-up period was 30 days. All subjects were examined three times (at baseline, 15 and 30 days after treatment). RESULTS AND CONCLUSION: After a month of treatment with recognan, there was an improvement of positive personality traits and a significant decrease in negative experiences, indicating the positive impact of the drug on the formation of positive personality manifestations and compensation for emotional disorders in patients with mild cognitive impairment and asthenic syndrome.

Use of antibiotics and asthma medication for acute lower respiratory tract infections in people with and without asthma: retrospective cohort study.

BACKGROUND: Antibiotics are overused in patients with acute lower respiratory tract infections (ALRTIs), but less is known about their use in patients with asthma, or the use of asthma medication for ALRTI in patients without asthma. Our aim was to describe the frequency, variation and drivers in antibiotic and asthma medication prescribing for ALRTI in adults with and without asthma in primary care. METHODS: A retrospective cohort analysis of patients aged ≥12 years, diagnosed with an ALRTI in primary care in 2014-15 was conducted using data from the Clinical Practice Research Datalink. Current asthma status, asthma medication and oral antibiotic use within 3 days of ALRTI infection was determined. Treatment frequency was calculated by asthma status. Mixed-effect regression models were used to explore between-practice variation and treatment determinants. RESULTS: There were 127,976 ALRTIs reported among 110,418 patients during the study period, of whom 17,952 (16%) had asthma. Respectively, 81 and 79% of patients with and without asthma received antibiotics, and 41 and 15% asthma medication. There were significant differences in between-practice prescribing for all treatments, with greatest differences seen for oral steroids (odds ratio (OR) 18; 95% CI 7-82 and OR = 94; 33-363, with and without asthma) and asthma medication only (OR 7; 4-18 and OR = 17; 10-33, with and without asthma). Independent predictors of antibiotic prescribing among patients with asthma included fewer previous ALRTI presentations (≥2 vs. 0 previous ALRTI: OR = 0.25; 0.16-0.39), higher practice (OR = 1.47; 1.35-1.60 per SD) and prior antibiotic prescribing (3+ vs. 1 prescriptions OR = 1.28; 1.04-1.57) and concurrent asthma medication (OR = 1.44; 1.32-1.57). Independent predictors of asthma medication in patients without asthma included higher prior asthma medication prescribing (≥7 vs. 0 prescriptions OR = 2.31; 1.83-2.91) and concurrent antibiotic prescribing (OR = 3.59; 3.22-4.01). CONCLUSION: Findings from the study indicate that antibiotics are over-used for ALRTI, irrespective of asthma status, and asthma medication is over-used in patients without asthma, with between-practice variation suggesting considerable clinical uncertainty. Further research is urgently needed to clarify the role of these medications for ALRTI.
