This is the first study to investigate the efficacy of intravenous iron in treating fatigue in nonanemic patients with low serum ferritin concentration. In a randomized, double-blinded, placebo-controlled study, 90 premenopausal women presenting with fatigue, serum ferritin ≤ 50 ng/mL, and hemoglobin ≥ 120 g/L were randomized to receive either 800 mg of intravenous iron (III)-hydroxide sucrose or intravenous placebo. Fatigue and serum iron status were assessed at baseline and after 6 and 12 weeks. Median fatigue at baseline was 4.5 (on a 0-10 scale). Fatigue decreased during the initial 6 weeks by 1.1 in the iron group compared with 0.7 in the placebo group (P = .07). Efficacy of iron was bound to depleted iron stores: In patients with baseline serum ferritin ≤ 15 ng/mL, fatigue decreased by 1.8 in the iron group compared with 0.4 in the placebo group (P = .005), and 82% of iron-treated compared with 47% of placebo-treated patients reported improved fatigue (P = .03). Drug-associated adverse events were observed in 21% of iron-treated patients and in 7% of placebo-treated patients (P = .05); none of these events was serious. Intravenous administration of iron improved fatigue in iron-deficient, nonanemic women with a good safety and tolerability profile. The efficacy of intravenous iron was bound to a serum ferritin concentration ≤ 15 ng/mL. This study was registered at the International Standard Randomized Controlled Trial Number Register (www.isrctn.org) as ISRCTN78430425. © 2011 by The American Society of Hematology.

Community acquired pneumonia (CAP) and sepsis are leading causes of hospitalisation after admission to a medical emergency department (ED). Identifying these potentially life-threatening diseases is not always easy due to often unspecific or minimal symptoms. However, quick application of antibiotics is known to be crucial and is correlated with better outcome. The international guidelines of the joint commission suggest a 4 hour-rule for optimal quality of care in CAP and sepsis. In this study we assessed the door-to-needle time (DNT) in patients admitted to our ED with the diagnosis of CAP and/or sepsis. Furthermore we investigated the CRB-65 score, its clinical performance and its influence on DNT. Retrospective observational study of all patients admitted and hospitalised through the ED of a Swiss hospital with the diagnosis of sepsis or pneumonia from June 2009 to June 2010 (n = 139). In 73% of the cases DNT was lower than the recommended 4 hours. In CAP, a correlation between the CRB-65 and DNT was not found (ρ = 0.13, p = 0.30). Further parameters, e.g. temperature or blood pressure did not improve DNT significantly. Analysis of the CRB-65 score was regularly impeded due to absent documented information on respiratory rate or confusion state. In most cases it was feasible to fulfill the 4 hours DNT. The CRB-65 score is an easy bedside tool, which was not routinely assessed by our emergency room personnel but its assessment did not affect DNT in our hospital.

Introduction: Osteoporosis is one of the commonest metabolic diseases of bone. Its possible causes may include thyroid hormonal dysfunction. The objective of this study was to evaluate the effects of hyperthyroidism and hypothyroidism on osseous tissue metabolism in premenopausal women. Material and methods: 38 women with hyperthyroidism, 40 with hypothyroidism and 41 healthy women participated in this study. Initially after 6 and 12 months, each patient underwent selected hormonal, immunological and biochemical tests, measurement of concentrations of bone turnover markers and densitometry were also performed. Results: On initial evaluation, lower cortical bone density was found in patients with hyperthyroidism (femoral neck). After 12 months, an increase in BMD was seen, but it was still lower than in the control group. Statistically significantly higher concentrations of bone turnover markers, decreasing from the sixth month of treatment, were noted only in the group with hyperthyroidism. Statistically significant differences were not noted in the femoral neck nor in the lumbar spine BMD in patients with hypothyroidism. Conclusions: Hyperthyroidism poses a negative effect on bone metabolism. Hypothyroidism in premenopausal females does not have any influence on bone density.

Organ transplantation is increasingly common in the older population, particularly among end-stage renal disease patients. The outcomes of transplantation are often inferior in older people compared with younger recipients, partly because of the side effects of immunosuppressive medication used after organ transplantation. In this paper, we explore treatment considerations for older transplant patients. The current commonly used immunosuppressive protocols have not been validated sufficiently in older organ recipients. The primary objective for the management of transplant recipients of all ages is to prevent rejection without increasing the risk of infection or other long-term complications. To avoid serious side effects related to immunosuppressive treatment, the clinician should consider modifying and tailoring the long-term regimen for individual patients. Modifications for older recipients include reduction in the dosage or avoidance of calcineurin inhibitors, with or without the introduction of a mammalian target of rapamycin inhibitor and discontinuing the use of corticosteroids. Such modifications must consider the individual risks and needs of each recipient. Treatment of an acute rejection episode should follow the same protocol as for younger recipients, but special attention is needed to ensure reduction in the total immunosuppressive load. One way to achieve this is to avoid anti-thymocyte globulin (ATG) induction and to use on-demand ATG treatment of rejection on the basis of the patient's CD3 T cell count. © 2013 Springer International Publishing Switzerland.

Ceftaroline is a new cephalosporin with bactericidal activity against resistant Gram-positive organisms, including methicillin- resistant Staphylococcus aureus (MRSA) and penicillin-resistant Streptococcus pneumoniae, as well as common Gram-negative organisms. This study tested the prodrug, ceftaroline fosamil, against a penicillin-sensitive and a penicillin- resistant strain of S. pneumoniae in an experimental rabbit meningitis model. The penetration of ceftaroline into inflamed meninges was approximately 14%. Ceftaroline fosamil was slightly superior to ceftriaxone against the penicillinsensitive strain and significantly superior to the combination of ceftriaxone and vancomycin against the penicillinresistant strain.
