OBJECTIVE: To compare maximum oxygen uptake and anaerobic threshold in patients with fibromyalgia (FM) and healthy sedentary controls matched by sex, age, weight, and body mass index. METHODS: Fifty women with FM aged 18-60 years and 50 healthy sedentary controls were studied. All were submitted to a maximum treadmill incremental test. Expired gas, ventilatory anaerobic threshold, and maximum oxygen uptake (VO2max) were evaluated. The influence of FM on quality of life was evaluated by questionnaires: the Fibromyalgia Impact Questionnaire and the Medical Outcomes Study Short-Form (SF-36). RESULTS: In patients with FM, the anaerobic threshold and peak oxygen uptake were significantly reduced. Maximum heartbeat rate was significantly lower in FM, indicating submaximum effort. Linear regression data showed a correlation between peak VO2 and the "Role-physical" domain of the SF-36. No such correlations were noted with anaerobic threshold. CONCLUSION: These results confirm the hypothesis of lower physical fitness in patients with FM. Considering that patients with FM do not achieve a maximum effort, ventilatory anaerobic threshold should be considered as a better fitness index than VO2max. 相似文献

The improvement in sickle cell disease (SCD) children receiving cromolyn sodium therapy prompted us to investigate its antisickling activity in vitro . The number of sickle cells was determined in deoxygenated blood samples from 15 children with severe SCD. At the eight concentrations tested, cromolyn sodium exhibited a significantly higher activity than pentoxifylline, the standard compound. Therefore cromolyn sodium would appear to be an interesting candidate for SCD therapy and deserves further in vivo investigations. 相似文献

The purpose of this research was to identify whether a certain set of drivers of satisfaction/perceived quality of healthcare (PQHC) could indirectly affect patients’ confidence/trust in the emergency department (ED).Patients were seen at an ED in the public hospital in Lisbon, Portugal between January and December 2016. Data were collected between May and November 2017, using a questionnaire, by mail or e-mail. The total sample size comprised 382 patients. The data analysis included structural equation modeling to test the conceptual model with specific drivers of satisfaction/PQHC (privacy; accessibility and availability; doctors; meeting expectations; waiting time for triage [perception]; waiting time to be called back by the doctor following examinations and/or tests [perception]; information about possible delays in receiving treatment/waiting times) and with the main outcome (confidence/trust in the ED) using path analysis.The analysis of the coefficients revealed that all the mediated paths are statistically significant (P ≤ .05). Although, altogether, the direct paths did not prove statistically significant (P > .05), the overall satisfaction with doctors (P ≤ .01) and meeting expectations (P = .01) can still directly explain the confidence/trust in the ED without the mediating role of satisfaction and PQHC. Hence, overall satisfaction with doctors and meeting expectations can influence, both directly and indirectly, confidence/trust in the ED. All other variables can only indirectly affect confidence/trust in the ED, either through PQHC or through satisfaction.Even though there are more variables that influence confidence/trust in the ED through PQHC (1)waiting time to be called back by the doctor following examinations and/or tests [perception]; 2) privacy; 3) accessibility and availability; 4) doctors; 5) meeting expectations than through satisfaction (1)waiting time for triage [perception]; 2) information about possible delays in receiving treatment/waiting times; 3) doctors; 4) meeting expectations), we observe the strongest contribution in the mediation model through satisfaction, which reveals its dominant role over PQHC. 相似文献

Objective: To examine the outcomes of pregnancy and newborn following an event of maternal medical compromise during pregnancy.Methods: A retrospective study was performed on all patients hospitalized following an event of medical compromise during pregnancy. Medical compromise was divided to acute or chronic bleeding, major or complicated operations, and admission to intensive care unit (ICU). Data collected included maternal, fetal, neonatal and child’s follow-up.Results: The study included 51 pregnant patients and 58 fetuses. The study group had increased risk of preterm deliveries (35.0 versus 6.5%, p?0.001), cesarean delivery (55.0 versus 22.7%, p?0.001) and low Apgar scores (5.0 versus 0.45%, p?=?0.002). Patients with acute bleeding had higher rates of cesarean sections, preterm deliveries, admissions to neonatal ICU and neonatal mortality. Two cases of fetal abnormalities included brain abnormalities and pericardial effusion. Three terminations of pregnancies were performed: two in patients in ICU due to severe maternal medical condition and one in the fetus with brain abnormalities.Conclusions: Maternal medical compromise during pregnancy increases the risk for preterm deliveries, cesarean delivery and low Apgar scores. Acute bleeding was the main cause of medical compromised and with the higher rates of adverse outcomes. 相似文献

The VATER/VACTERL association describes the combination of congenital anomalies including vertebral defects, anorectal malformations, cardiac defects, tracheoesophageal fistula with or without esophageal atresia, renal malformations, and limb defects. As mutations in ciliary genes were observed in diseases related to VATER/VACTERL, we performed targeted resequencing of 25 ciliary candidate genes as well as disease‐associated genes (FOXF1, HOXD13, PTEN, ZIC3) in 123 patients with VATER/VACTERL or VATER/VACTERL‐like phenotype. We detected no biallelic mutation in any of the 25 ciliary candidate genes; however, identified an identical, probably disease‐causing ZIC3 missense mutation (p.Gly17Cys) in four patients and a FOXF1 de novo mutation (p.Gly220Cys) in a further patient. In situ hybridization analyses in mouse embryos between E9.5 and E14.5 revealed Zic3 expression in limb and prevertebral structures, and Foxf1 expression in esophageal, tracheal, vertebral, anal, and genital tubercle tissues, hence VATER/VACTERL organ systems. These data provide strong evidence that mutations in ZIC3 or FOXF1 contribute to VATER/VACTERL. 相似文献
