In this study, we assessed the incidence, contributing factors and outcome of prolonged neutropenia above 7 days and of bacteraemia in patients with lymphoma and multiple myeloma who underwent autologous haematopoietic stem cell transplantation (AHSCT) without antibacterial prophylaxis.
Methods
This is a retrospective chart review of 190 adult patients who underwent AHSCT between 2005 and 2015 at a Lebanese hospital.
Results
Neutropenia of 7 days duration and longer was documented in 66% of the patient population. Through univariate analysis, patients with lymphoma were significantly more likely to have prolonged neutropenia (≥?7 days) compared to those with myeloma. Mucositis above grade 3, diarrhoea and fever were more likely to occur in patients with prolonged neutropenia. Bacteraemia was documented in 12.6% of the patients. Total mortality rate was 3.7%, and that attributed to bacteraemia was 12.5% in the bacteraemia subgroup. Among bacterial isolates recovered from clinical specimens (89 isolates), 70% were Gram-negative, of which 57% were fluoroquinolone susceptible. Ninety-five percent of the Gram-negative bacteria causing bacteraemia were susceptible to fluoroquinolones.
Conclusion
Bacterial pathogens causing bacteraemia were still highly susceptible to fluoroquinolones, despite the high prevalence of fluoroquinolone-resistant strains in the general bacterial ecology. Accordingly, the pertinence of fluoroquinolone prophylaxis in the AHSCT setting warrants further investigation. Moreover, continuous surveillance of local antibiograms in this patient population has become a must in an era of preponderant antibiotic resistance.
IntroductionEdible mushrooms have a great nutritional value including high protein, essential amino acids, fiber, vitamins (B1, B2, B12, C, and D), minerals (calcium [Ca], potassium [K], magnesium [Mg], sodium [Na], phosphorus [P], copper [Cu], iron [Fe], manganese [Mn], and selenium [Se]), low fatty foods, and sodium. The objective of this systematic review was to determine the relationship between edible mushroom consumption and overall cardiovascular risk.MethodsWe systematically searched Ovid MEDLINE, Embase, Ovid Cochrane Database of Systematic Reviews, Scopus, and Web of Science from database inception from 1966 through August 2020 for observational studies that reported the association between edible mushroom consumption and cardiovascular risk. Two investigators independently reviewed data. Conflicts were resolved through consensus discussion.ResultsOf 1479 studies, we identified 7 prospective studies. Edible mushroom consumption may have favorable effects on lipid profiles by changing some metabolic markers such as low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, total cholesterol, and triglycerides. Moreover, edible mushroom consumption is probably associated with reduced mean blood pressure. The beneficial overall cardiovascular risk, stroke risk, and coronary artery disease of edible mushroom consumption are not consistent.ConclusionsEdible mushroom consumption has not been shown to conclusively affect cardiovascular risk factors to date. However, potential health benefits may exist, including a favorable alteration of lipid profiles and blood pressure reduction. 相似文献
Introduction: Primary biliary cirrhosis (PBC) is a chronic autoimmune liver disease mostly seen in middle-aged women characterized by progressive nonsuppurative destruction of small bile ducts resulting in intrahepatic cholestasis, parenchymal injury and ultimately end-stage liver disease. Despite major breakthroughs in our understanding of PBC, there remains only one FDA-approved agent for treatment: ursodeoxycholic acid (UDCA) to which one-third of patients are unresponsive.
Areas covered: Biochemical response to treatment with UDCA is associated with excellent survival rates in PBC patients. However, there is a need for alternative treatments for nonresponders. Results from human epidemiological and genetic studies as well as preclinical studies in PBC animal models have provided a strong impetus for the development of new therapeutic agents. In this review, we discuss the recent advances in translational research in PBC focusing on promising therapeutic approaches, namely immune-based targeted therapies and agents targeting the synthesis and circulation of bile acids.
Expert opinion: We are in a new era for the development of novel therapies for PBC. Data on fibrates, budesonide and obeticholic acid offer encouragement for nonresponders to UDCA. 相似文献

Chronic gastric motility disorders have proven intractable to most traditional therapies. Twenty-six patients with chronic nausea and vomiting were treated with a behavioral technique, autonomic training (AT) with directed imagery (verbal instructions), to help facilitate physiological control. After treatment, gastrointestinal symptoms decreased by >30% in 58% of the treated patients. We compared those improved patients to the 43% who did not improve significantly. No significant differences existed in baseline symptoms and autonomic measures between both groups. However, baseline measures of gastric emptying and autonomic function predicted treatment outcome. Patients who improved manifested mild to moderate delay in baseline gastric emptying measures. The percent of liquid gastric emptying at 60 mins and the sympathetic adrenergic measure of percent of change in the foot cutaneous blood flow in response to cold stress test predicted improvement in AT outcome, with clinical diagnostic values of 77% and 71%, respectively. We conclude that AT treatment can be efficacious in some patients with impaired gastric emptying and adrenergic dysfunction. More work is warranted to compare biofeedback therapy with gastric motility patients and controls in population-based studies. 相似文献
BACKGROUND: Heart failure remains a progressive disease with incremental morbidity and mortality despite optimal medical therapy. A growing body of evidence suggests that progressive left ventricular (LV) remodeling is directly related to a deterioration in LV performance and untoward clinical outcomes for heart failure patients. Preclinical and early phase I clinical studies with the CorCap Cardiac Support Device (CSD), a passive cardiac support device that prevents cardiac remodeling, have shown that it is safe and is associated with improvements in LV structure and function, as well as patient symptomatology. METHODS AND RESULTS: The Acorn Pivotal Trial is a pivotal prospective, randomized, evaluation of the CorCap CSD in patients with New York Heart Association class III-IV heart failure. Patients will be enrolled into one of two different strata. Patients who require a mitral valve repair/replacement (MVR) will fall into the "MVR stratum" and will be randomized to either treatment (MVR surgery plus the CSD) or control (MVR surgery alone). Patients who do not have a clinical indication for MVR surgery will fall into the "no-MVR stratum" and will also be randomized to either treatment (CSD implant plus optimal medical therapy) or control (optimal medical therapy alone). A total of 300 patients (150 treatment and 150 control) will be enrolled. The primary endpoint of the trial is the change in clinical status from baseline to the end of the efficacy phase (1 year), as determined by a clinical composite score. Patients will be classified as improved, worsened, or unchanged based upon patient vital status, the occurrence of a major cardiac procedure indicative of heart failure progression, and a change in the assessment of New York Heart Association functional class. CONCLUSIONS: The Acorn Pivotal Trial will formally test the hypothesis that preventing LV remodeling using a passive cardiac support device will favorably impact the untoward natural history of heart failure and thus represents an important departure from all previous medical and device studies that have been reported to date. 相似文献
