Sarcopenia in hemodialysis patients from Buenos Aires, Argentina

Objectives@#Sarcopenia is the loss of skeletal muscle mass and function that occurs with aging that can lead to greater morbidity and mortality. Chronic kidney disease and hemodialysis (HD) favors the development of sarcopenia. We studied the prevalence of sarcopenia and its components using European Working Group on Sarcopenia in Elderly People 2 proposed criteria and risk factors for its development in HD patients. @*Methods@#In 100 adult HD patients, we evaluated: hand grip strength (HGS), muscle mass by dual energy X-ray absorptiometry and physical performance (gait-speed and sit-stand test). @*Results@#Sixty patients were male and 40 were female; mean age 55.6 years. Prevalence of sarcopenia was 16% (11.1% in males and 25% in females; P ¼ 0.05); 7% had severe sarcopenia. Prevalence of low HGS was 33% in males and 28% in females; low muscle mass was 30% in males but 70% in females and low physical performance 23% in males and 45% in females. Falls were reported by 23 patients. Patients with lower HGS had a higher prevalence of falls in the last year (40% two or more falls; P ¼ 0.03). Only females with sarcopenia had lower bone mineral content. Neither age, body mass index, time on dialysis, or prevalence of diabetes predicted sarcopenia. @*Conclusions@#A significant proportion of dialysis patients had sarcopenia, more frequent in females. Low HGS was associated with a higher prevalence of falls. Only females with sarcopenia had lower bone mineral content.

Severe atypical pneumonia in critically ill patients: a retrospective multicenter study.

BACKGROUND: Chlamydophila pneumoniae (CP) and Mycoplasma pneumoniae (MP) patients could require intensive care unit (ICU) admission for acute respiratory failure. METHODS: Adults admitted between 2000 and 2015 to 20 French ICUs with proven atypical pneumonia were retrospectively described. Patients with MP were compared to Streptococcus pneumoniae (SP) pneumonia patients admitted to ICUs. RESULTS: A total of 104 patients were included, 71 men and 33 women, with a median age of 56 [44-67] years. MP was the causative agent for 76 (73%) patients and CP for 28 (27%) patients. Co-infection was documented for 18 patients (viruses for 8 [47%] patients). Median number of involved quadrants on chest X-ray was 2 [1-4], with alveolar opacities (n = 61, 75%), interstitial opacities (n = 32, 40%). Extra-pulmonary manifestations were present in 34 (33%) patients. Mechanical ventilation was required for 75 (72%) patients and vasopressors for 41 (39%) patients. ICU length of stay was 16.5 [9.5-30.5] days, and 11 (11%) patients died in the ICU. Compared with SP patients, MP patients had more extensive interstitial pneumonia, fewer pleural effusion, and a lower mortality rate [6 (8%) vs. 17 (22%), p = 0.013]. According MCA analysis, some characteristics at admission could discriminate MP and SP. MP was more often associated with hemolytic anemia, abdominal manifestations, and extensive chest radiograph abnormalities. SP-P was associated with shock, confusion, focal crackles, and focal consolidation. CONCLUSION: In this descriptive study of atypical bacterial pneumonia requiring ICU admission, mortality was 11%. The comparison with SP pneumonia identified clinical, laboratory, and radiographic features that may suggest MP or CP pneumonia.

Management of acute exacerbations of chronic obstructive pulmonary disease (COPD). Guidelines from the Société de pneumologie de langue française (summary).

Chronic obstructive pulmonary disease (COPD) is the chronic respiratory disease with the most important burden on public health in terms of morbidity, mortality and health costs. For patients, COPD is a major source of disability because of dyspnea, restriction in daily activities, exacerbation, risk of chronic respiratory failure and extra-respiratory systemic organ disorders. The previous French Language Respiratory Society (SPLF) guidelines on COPD exacerbations were published in 2003. Using the GRADE methodology, the present document reviews the current knowledge on COPD exacerbation through 4 specific outlines: (1) epidemiology, (2) clinical evaluation, (3) therapeutic management and (4) prevention. Specific aspects of outpatients and inpatients care are discussed, especially regarding assessment of exacerbation severity and pharmacological approach.

La bronchopneumopathie chronique obstructive (BPCO) est la maladie respiratoire chronique dont le poids sur la santé publique est le plus grand par sa morbidité, sa mortalité et les dépenses de santé qu'elle induit. Pour les individus atteints, la BPCO est une source majeure de handicap du fait de la dyspnée, de la limitation d'activité, des exacerbations, du risque d'insuffisance respiratoire chronique et des manifestations extra-respiratoires qu'elle entraîne. Les précédentes recommandations de la Société de pneumologie de langue française (SPLF) sur la prise en charge des exacerbations BPCO date de 2003. Se fondant sur une méthodologie adaptée de GRADE, le présent document propose une actualisation de la question des exacerbations de BPCO en développant un argumentaire couvrant quatre champs d'investigation : (1) épidémiologie, (2) évaluation clinique, (3) prise en charge thérapeutique et (4) prévention. Les modalités spécifiques de la prise en charge hospitalière et ambulatoire y sont discutées, particulièrement les aspects relevant de l'évaluation de la sévérité de l'exacerbation et de la prise en charge pharmacologique.(AU)

Modification of cervical length after cervical pessary insertion: correlation weeks of gestation.

OBJECTIVES: To observe the modifications in cervical length (CL) in patients with and without cervical pessary (Arabin® ASQ 65/25/32) and correlate these modifications with gestational age at delivery. STUDY DESIGN: Prospective study of asymptomatic singleton pregnancies (PECEP-Trial) between weeks 20 + 0 and 23 + 6 with maternal short cervix (<25 mm) randomised into two groups: expectant management and cervical pessary. RESULTS: This study included 380 pregnant women: 190 with pessary and 190 without pessary. Mean CL in both groups at the time of randomisation showed no statistically-significant differences (pessary group: 19.0 mm and management group: 19.0 mm; p = 0.9). Mean CL measured after randomisation was 15.4 mm in patients of the expectant management group and 21.5 mm in the pessary group. These differences were statistically significant (p < 0.0001). When means at randomisation and at the second measurement were compared, CL had decreased by 3.6 mm in the expectant management group and increased by 2.6 mm in the pessary group; this difference was statistically significant (p < 0.0001). Coefficients of correlation showed that among patients of both groups with the same CL at 20 weeks of gestation, those with a pessary gave birth later. CONCLUSIONS: Insertion of an Arabin cervical pessary increased CL in asymptomatic patients with a short cervix, which correlated with shorter gestational age at delivery. The cervical pessary halted the progressive decrease in CL, which correlated with longer gestational age at delivery.

Factors associated with effective reassessment of antibiotic therapy on day 3.

UNLABELLED: Reassessment of antibiotic therapy (RA) after 3 days is constitutive of French antibiotic stewardship. This delay is required because of the need for clinical reappraisal and for obtaining microbiological data. Our aim was to determine the factors associated with an effective RA. PATIENTS AND METHOD: A prospective study was made in a 350-bed general hospital in which all prescriptions are computerized and validated daily by prescribers. All curative antibiotic therapies were reassessed during 4 weeks. RA was defined as effective if the initial antibiotic treatment was modified. All clinical, biological, and radiological data having contributed to the initial prescription and to RA were recorded during bedside visit with the prescribers, two hospital physicians and one infectious diseases specialist. RESULTS: In one month, 148 antibiotic treatments were reassessed. Pulmonary, digestive, and urinary infections accounted for two thirds of the cases. An effective RA was recorded in 28 cases (19%) and associated with hospitalization in the ICU (P=0.001), imaging supporting the diagnosis (P=0.016), and persistence or aggravation of clinical signs (P=0.007). Microbiological findings were not contributive to an effective RA. CONCLUSION: RA was associated to hospitalization in the ICU, to an inflammatory syndrome, and to the clinical outcome after 3 days. These results should help to improve the implementation of infectious diseases advice.

[Diagnostic strategy for acute respiratory failure in patients with haematological malignancy]. / Stratégie diagnostique dans l'insuffisance respiratoire aiguë des patients d'oncohématologie.

INTRODUCTION: About 15% of patients with haematological malignancy develop acute respiratory failure (ARF), necessitating admission to intensive care where their mortality is of the order of 50%. STATE OF THE ART: The prognosis of these patients is not determined by the pathological characteristics of the malignancy but by the cause of the acute respiratory failure. In effect, the need to resort to mechanical ventilation in the presence of dysfunction of other organs dominates the prognosis. Even if the use of non-invasive ventilation in these patients has reduced the need for intubation and reduced the mortality, its prolonged use in the most severely affected patients prevents the optimal diagnostic and therapeutic management. PERSPECTIVES: Fibreoptic bronchoscopy with broncho-alveolar lavage (BAL) is considered the cornerstone of aetiological diagnosis but its diagnostic effectiveness is poor, at best 50%, and this has led to increasing interest in high resolution CT scanning and regularly reawakens a transitory enthusiasm for surgical lung biopsy. Furthermore, in hypoxaemic patients, fibreoptic bronchoscopy with BAL may be the origin of the resort to mechanical ventilation, and thus increased mortality. The place of recently developed non-invasive tools is under evaluation. In effect, though the individual performance of diagnostic molecular techniques on sputum, blood, urine or naso- pharyngeal secretions has been established, the combination of these tools as an alternative to BAL has not yet been reported. CONCLUSION: This review deals with acute respiratory failure in patients with haematological malignancy. It includes a review of the recent literature and considers the current controversies, in particular the risk-benefit balance of fibreoptic bronchoscopy with BAL in severely hypoxaemic patients.
