The susceptibility to infection, the pathogenesis and the clinical manifestations of tuberculosis (TB) depend on the immunological status of the host. Immunological status is largely determined by age and comorbidities, but is also affected by other less well known factors. In Spain, most incidental cases of TB arise from the reactivation of remotely acquired latent infections and are favored by the aging of the population and the use of aggressive immunosuppressive therapies. The diagnosis and management of TB in these circumstances is often challenging. On the one hand, the atypical presentation with extrapulmonary involvement may delay diagnosis, and on the other, the toxicity and interactions of the antituberculous drugs frequently make treatment difficult. Immigration from resource-poor, high incidence TB countries, where the social and economic conditions are often suboptimal, adds a new challenge to the control of the disease in Spain. This chapter summarizes our current knowledge of epidemiological, clinical and treatment aspects of TB in particularly susceptible populations. © 2011 Elsevier España S.L.

This paper summarizes the current understanding of the biology of somatostatin receptor (sst), role of immunotherapy in neuroendocrine tumor (NET), new agents for PPRT, and methods to assess response and clinical benefit in NET. One of the most interesting aspects of sst biology is the recent discovery of truncated variants of the sst5 receptor subtype with unique tissue distribution and response to somatostatin (SST). These truncated receptors are associated with bad patient prognosis, decreased response to SST analogs, and may be new targets for diagnoses and treatment. IFN remains a cost-effective agent, particularly in classic mid gut carcinoids, and there is interest to continue examining immunotherapy's in this disease. PRRT remains a key strategy for treatment and imaging. In addition to the classic agents, there are a series of new agents targeting other receptors such as the incretin receptors (GLP-1R; GIPR) and other G-protein coupled receptors with great potential. With regards to therapy monitoring, the most commonly used criteria are Response Criteria Evaluation in Solid Tumors (RECIST). However, for different reasons, these criteria are not very useful in NET. Incorporation of other criteria such as Choi as well as functional imaging assessment with PET would be of great interest in this area. © 2014 Springer Science+Business Media New York.

Objective: n-3 polyunsaturated fatty acids (contained in fish oil) have been shown to beneficially influence infection rate and clinical outcomes in surgical patients probably due to their immunomodulatory action. In contrast, study results of fish oil administration in critically ill patients are controversial. The aim of this study was to investigate the effects of n-3 polyunsaturated fatty acids on the prevalence of nosocomial infections and clinical outcomes in medical and surgical critically ill patients. Design: Prospective, multicenter, randomized, comparative, double- blind study. Setting: Seventeen Spanish ICUs during 4 years. Subjects: A total of 159 medical and surgical intensive care patients with Acute Physiology and Chronic Health Evaluation II score more than or equal to 13, expected to require total parenteral nutrition for at least 5 days. Interventions: Patients received total parenteral nutrition prepared either with a lipid emulsion containing 10% fish oil or a fish oil-free lipid emulsion. The prevalence of nosocomial infections was detected during 28 days of ICU stay. Patients were followed 6 months after discharge from the ICU for length of hospital stay, hospital mortality, and 6-month mortality. Measurements and Main Results: The number of patients with nosocomial infections was significantly reduced in the fish oil-receiving group (21.0% vs 37.2%, p = 0.035) and the predicted time free of infection was prolonged (21 ± 2 vs 16 ± 2 d, p = 0.03). No significant differences were detected for ICU, hospital, and 6-month mortality. Conclusions: The results show that administration of n-3 polyunsaturated fatty acids reduces the risk of nosocomial infections and increases the predicted time free of infections in critically ill medical and surgical patients. The administration of n-3 polyunsaturated fatty acids was safe and well tolerated.

Infections related to the health-care system are those associated with health care practices in hospitalized patients as well as in out-patients with health-care contact. Nosocomial infections affect 5% of in-patients, and carry a high morbidity, mortality and economic cost. The main types of nosocomial infections are related to invasive procedures, and include respiratory tract infection, surgical site infections, urinary tract infections, and vascular catheter bacteremia. It has been shown that the application of checklists and a bundle of measures are useful in preventing these infections. Epidemiological surveillance, defined as the gathering of information to take actions, is the basis of infection control programs. These have evolved from a global surveillance targeted at processes and indicators of nosocomial infection. The comparison of these indicators can be useful in establishing preventive measures. © 2013 Elsevier España, S.L. All rights reserved.

The non -peptide vasopressin antagonists (VPA), called vaptans, were developed in the 1990s to antagonize both the pressor and antidiuretic effects of vasopressin.There are three subtypes of VPA receptors: V1a, V1b and V2. V1a receptors are widely distributed in the body, mainly the blood vessels and myocardium. The V1b receptors are located mainly in the anterior pituitary gland and play a role in ACTH release. V2 receptors are located in the collecting tubular renal cells. Both V1a and V1b receptors act through the intracellular phosphoinositol signalling pathway, Ca++ being the second messenger. V2 receptors work through AMPc generation, which promotes aquaporin 2 (AQP2) trafficking and allows water to enter the cell.The vaptans act competitively at the AVP receptor. The most important are mozavaptan, lixivaptan, satavaptan and tolvaptan, all of which are selective V2 antagonists and are administered through the oral route. In contrast, conivaptan is a dual V1 and V2 antagonist administered through the endovenous route. The main characteristics of vaptans are their effect on free water elimination without affecting electrolyte excretion. There are several studies on the effects of these drugs in hypervolemic hyponatremia (heart failure, hepatic cirrhosis) as well as in normovolemic hyponatremia (inappropriate secretion of ADH [SIADH]).Current studies show that the vaptans are effective and well tolerated, although knowledge of these drugs remains limited. There are no studies of the use of vaptans in severe hyponatremia. Osmotic demyelination syndrome due to excessively rapid correction of hyponatremia has not been described. © 2010 Sociedad Española de Endocrinología y Nutrición.

We present a systematic review of clinical trials to evaluate the efficacy of infusing local anesthetic through a catheter placed in the abdominal surgical wound. The Jadad (Oxford) scoring system was used to select trials. The variables considered in relation to each trial selected were as follows: type of intervention and incision; type, dose, and concentration of local anesthetic; site where the catheter was placed; rescue analgesia required; opioid use; and incidence of adverse events. Fifteen clinical trials with a mean Jadad score of 4.6 were selected. The 1139 patients enrolled in the trials were grouped according to catheter placement: subfascial (6 trials), subcutaneous (8 trials), and both (1 trial). Six additional unpublished trials registered at ClinicalTrials.gov were also located. Surgical wound analgesia is a safe technique whose effectiveness has been observed in cesarean sections and hysterectomies performed with Pfannenstiel incisions. Outcomes for other types of surgery are inconsistent. There is a lack of studies of the optimal site for catheter placement as well as of adequate anesthetic concentration and volume.

Introduction: Sunitinib is an oral oxindol derivative and a potent inhibitor of vascular endothelial growth factor receptor and platelet-derived growth factor receptor and a multitargeted tyrosine-kinase inhibitor, which has antitumor and antiangiogenic activity due to the selective inhibition that can stabilize progressive metastatic disease. The aim of this review is to expose whether the drug could be considered as a new promising therapy compared with other tyrosine-kinase inhibitors. Areas covered: In seven open-label studies carried out with sunitinb, the drug showed its anti-tumoral activity in advanced differentiated thyroid carcinoma and in medullary thyroid carcinoma. The reported objectives in advanced differentiated thyroid carcinoma, partial response ranges 13% to 55.5%, stable disease ranges 44.4% to 68%, progressive disease ranges 10% to 21% of patients, progression free survival ranges 3 to 13.3% months. In medullary thyroid carcinoma, PR ranges 0% to 55%, SD ranges 44.4% to 87.5%, PD ranges 7% to 18.8% and progression free survivalranges seven to 21 months. Expert opinion: Sunitinib has demonstrated a potent anti-tumoral activity in differentiated thyroid carcinoma and in medullary thyroid carcinoma, but the results of the open-label trials single arm are limited. Further investigations with this agent with randomized trials are warranted. © 2016 Informa UK Limited, trading as Taylor & Francis Group.

Interferon-γ-based assays, collectively known as IFN-γ release assays (IGRAs), have emerged as a reliable alternative to the old tuberculin skin test (TST) for the immunodiagnosis of tuberculosis (TB) infection. The 2 commercially available tests, the enzyme-linked immunosorbent assay (ELISA), QuantiFERON-TB Gold Intube (QFT-IT), and the enzyme-linked immunospot assay (ELISPOT), T-SPOT.TB, are more accurate than TST for the diagnosis of TB, since they are highly specific and correlate better with the existence of risk factors for the infection. According to the available data, T-SPOT.TB obtains a higher number of positive results than QFT-IT, while its specificity seems to be lower. Although the sensitivity of the IFN-γ -based assays may be impaired to some extent by cellular immunosuppression and extreme ages of life, they perform better than TST in these situations. Data from longitudinal studies suggest that IFN-γ-based tests are better predictors of subsequent development of active TB than TST; however this prognostic value has not been consistently demonstrated. This review focuses on the clinical use of the IFN-γ -based tests in different risk TB groups, and notes the main limitations and areas for future development. © 2011 Elsevier España S.L.
[The emergency department short stay unit and the hospital at home as alternatives to standard inpatient hospitalisation]. [La unidad de corta estancia de urgencias y la hospitalización a domicilio como alternativas a la hospitalización convencional.]

The emergency short stay unit (ESSU) is a support unit for the accident and emergency services and a clear alternative to the conventional hospitalisation of patients needing urgent care, who are affected by the re-aggravation of certain chronic diseases (whether seasonal o not) or by moderate short-evolution pathologies. Hospitalisation at home is one alternative making it possible to undertake the care and treatment characteristic of a hospital in the home of the patient, with greater comfort and intimacy. The origin of the patient might be the conventional hospital, the emergency service or ESSU. A suitable selection of patients is essential in both alternatives to conventional hospitalisation, using strict criteria that are both clinical and socio-family in nature. Their correct use assures a significant saving in stays in conventional hospital units, a reduction of the average stay in hospital medical and surgical services and less pressure on the accident and emergency service, since they increase the availability of beds both for programmed admission and for urgent admission in conventional hospitalisation and thus improve patient outflow in the accident and emergency service.
