Polymerase chain reaction (PCR) testing is one of the better techniques for viral detection in nasopharyngeal swabs. The objective of this study was to assess the percentage of positive swabs and to determine whether there were differences according to PCR positivity. A retrospective study of 362 patients with flu syndrome attended at the Emergency Department between July 15 and December 15, 2009, in whom PCR of nasopharyngeal swabs for the detection of H1N1 2009 influenza virus was performed. Those cases in which swab testing was adequately requested were identified, and patients were divided into two groups according to positive or negative results for H1N1 2009 influenza virus. Nasopharyngeal swab was inadequately ordered in 87. In the remaining 275 patients, PCR was positive in 141. Patients with positive nasopharyngeal swabs were younger (mean [SD] age 36.1 [15] vs 42.3 [18] years, P= 0.002), had lower white blood cell, neutrophil and lymphocyte counts, lower serum concentrations of C-reactive protein (5.15 [5] vs 10.5[12] mg/dL, P= 0.036) and lower incidence of radiological infiltrates (20.5% vs 33%, P= 0.036). In the logistic regression analysis, age, serum C-reactive protein levels, and lymphocyte count were independently associated with a positive nasopharyngeal swab. About 50% of patients with flu syndrome had positive nasopharyngeal swabs for H1N1 2009 influenza virus. Age, C-reactive protein, and lymphocyte count were independent predictors of positivity.

Antimicrobial resistance has increased during the last few years, representing a public health concern. Among Gram-positive organisms, methicillin-resistant Staphylococcus aureus (MRSA) and Streptococcus pneumoniae are paradigms of resistance and of the dispersion of multiresistant clones. Ceftaroline, a broadspectrum cephalosporin that includes MRSA and penicillin-resistant S. pneumoniae, is the first β-lactam antibiotic useful in infections due to MRSA. Phase-III clinical trials have demonstrated its efficacy in the treatment of community-acquired pneumonia and in skin and soft tissue infections, which are the current indications for ceftaroline. Due to its microbiological and pharmacological (PK/PD) profiles, these indications could be expanded to include bacteremia, endocarditis, and even osteoarticular infections. Another notable feature is the activity of this drug against Gram-negative bacilli susceptible to thirdgeneration cephalosporins, indicating that ceftaroline could be useful when these organisms are suspected or demonstrated in polymicrobial infections. Clinical follow-up of ceftaroline use will more clearly define future ceftaroline indications. © 2014 Elsevier España, S.L. All rights reserved. Source

The aim of this study was to assess the impact of vancomycin (VAN) versus linezolid (LZD) on renal function in patients with renal failure (RF) admitted to intensive care units. This was a multicenter, retrospective, comparative cohort study. Renal failure patients were treated with VAN or LZD for proven or suspected infections by multiresistant Gram-positive cocci. Changes in plasma creatinine levels and creatinine clearance at the start and end of treatment were used as endpoints. A total of 147 patients were treated with VAN (group A, n=68) or LZD (group B, n=79). Group B included more patients with diabetes mellitus [9 (13.2%) vs. 25 (31.6%); p = 0.007], septic shock [39 (57.4%) vs. 60 (75.9%); p = 0.013] and greater RF (mean ClCr 42.24 ml/min vs. 37.57 ml/min; p = 0.04). Renal function improved in patients from both groups who did not require renal replacement therapy. A greater improvement was seen in group B [percent decrease in Cr (27.94 vs. 9.48; p = 0.02) and percent increase in ClCr (95.96 vs. 55.06; p = 0.05)]. In group A, nine patients (13.2%) experienced an antibiotic-related increase in RF, and antibiotic was discontinued in five patients due to adverse effects. It is reasonable to avoid use of VAN in critically ill patients with acute renal failure. © 2011 Springer-Verlag. Source

Introduction: Perioperative complications influence long- and short-term outcomes after esophagectomy. The absence of a standardized system for defining and recording complications and quality measures after esophageal resection has meant that there is wide variation in evaluating their impact on these outcomes. Methods: The Esophageal Complications Consensus Group comprised 21 high-volume esophageal surgeons from 14 countries, supported by all the major thoracic and upper gastrointestinal professional societies. Delphi surveys and group meetings were used to achieve a consensus on standardized methods for defining complications and quality measures that could be collected in institutional databases and national audits. Results: A standardized list of complications was created to provide a template for recording individual complications associated with esophagectomy. Where possible, these were linked to preexisting international definitions. A Delphi survey facilitated production of specific definitions for anastomotic leak, conduit necrosis, chyle leak, and recurrent nerve palsy. An additional Delphi survey documented consensus regarding critical quality parameters recommended for routine inclusion in databases. These quality parameters were documentation on mortality, comorbidities, completeness of data collection, blood transfusion, grading of complication severity, changes in level of care, discharge location, and readmission rates. Conclusions: The proposed system for defining and recording perioperative complications associated with esophagectomy provides an infrastructure to standardize international data collection and facilitate future comparative studies and quality improvement projects. © 2015 Wolters Kluwer Health, Inc.

Clinical Drug Investigation

The combination of calcium with vitamin D (vitamin D3 colecalciferol) forms the basis of preventive and therapeutic regimens for osteoporosis. A number of studies have suggested that the combination of calcium and vitamin D is effective when administered at respective dosages of at least 1200mg and 800IU per day, although efficacy is, as expected, affected by patient compliance. Overall, treatment with this combination appears to be effective in reducing the incidence of non-vertebral and hip fractures. Also, in all drug studies (of antiresorptive and anabolic agents and strontium ranelate) that demonstrated a reduction in risk of osteoporotic fractures, patients also took calcium and vitamin D supplements. An important finding in this regard is that vitamin D levels have been demonstrated to be inadequate in more than half of women treated for osteoporosis in the US and Europe.The capacity of the small intestine to absorb calcium salts depends on the solubility and ionization of the salts. These properties vary for different salts, with fasting calcium citrate absorption being greater than that of calcium lactogluconate and calcium carbonate. Calcium citrate formulations taken between meals may help to prevent abdominal distension and flatulence, as well as minimize the risk of renal calculus formation, thus helping to optimize patient compliance. Therefore, calcium citrate combined with vitamin D is the combination of choice for the prevention or treatment of osteoporosis. © 2011 Adis Data Information BV. All rights reserved. Source
