Immunotherapy in Melanoma,Gastrointestinal (GI), and Pulmonary Malignancies

Oncologic immunotherapy involves stimulating the immune system to more effectively identify and eradicate tumor cells that have successfully adapted to survive the body''s natural immune defenses. Immunotherapy has shown great promise thus far by prolonging the lives of patients with a variety of malignancies, and has added a crucial new set of tools to the oncologists'' armamentarium. The aim of this paper is to provide an overview of immunotherapy treatment options that are currently available and under active research for melanoma, gastrointestinal (esophageal, gastric, pancreatic, and colorectal), and pulmonary malignancies. Potential biomarkers that may predict favorable responses to immunotherapies are discussed where applicable, as are future avenues of research in this rapidly evolving field.     

17q12-21 and asthma: interactions with early-life environmental exposures

Background17q12-21 polymorphisms are associated with asthma presence and severity across different populations.ObjectiveTo extensively investigate the genes in this region among Croatian schoolchildren in a case-control study, taking account of early-life environmental exposures.MethodsWe included 423 children with asthma and 414 controls aged 5 to 18 years. Fifty-one haplotype tagging single-nucleotide polymorphisms (SNPs) were genotyped (GSDMA, GSDMB, ORMDL3, IKZF3, ZPBP2, and TOP2). Data on exposure to smoking and furry pet ownership were collected using a validated questionnaire. Information on severe asthma exacerbations with hospital admission were retrieved from hospital notes. All patients underwent spirometry.ResultsWe found 2 SNPs (1 novel rs9635726 in IKZF3) to be associated with asthma. Among children with asthma, 4 SNPs (in ZPBP2, GSDMB, and GSDMA) were associated with hospital admissions and 8 SNPs with lung function. One SNP (rs9635726) remained significantly associated with a predicted forced expiratory volume in 1 second after false discovery rate correction. Nine markers across 5 genes showed interaction with early-life environmental tobacco smoke (ETS) exposure in relation to asthma and 2 with furry pet ownership. Among children with asthma, we observed significant interactions between early-life ETS exposure and 3 SNPs for lung function and among early-life ETS exposure, 3 SNPs (in ORMDL3 and GSDMA), and hospital admission with asthma exacerbation. Three SNPs (in ORMDL3) interacted with current furry pet ownership in relation to hospital admissions for asthma exacerbation.ConclusionOur results indicate that several genes in the 17q12-21 region may be associated with asthma. This study confirms that environmental exposures may need to be included into the genetic association studies.     

Variabilidad en el consumo de recursos en pacientes con espondiloartritis en España. Datos descriptivos preliminares del estudio emAR II

ObjectiveOur objective was to describe the variability in the management of spondyloarthritis (SA) in Spain in terms of healthcare resources and their use.MethodsA review of 1168 medical files of patients seen in randomly selected Spanish hospital rheumatology departments. We analyzed demographic variables and variables related to the consumption of health resources.ResultsThe total number of visits to rheumatology were 5,908 with a rate of 254 visits/100 patient-years. The total number of visits to rheumatology specialty nurses was 775, with a rate of 39 visits/100 patient-years, and there were 446 hospitalizations, representing a rate of 22 per 100 patient-years. The number of admissions due to SA was 89, with a rate of 18 admissions/100 patient-years. Total visits to other specialists was 4,307 with a rate of 200/100 patient-years. The total number of orthopedic surgeries was 41, which leads to a rate of 1.8 surgeries/100 patient-years.ConclusionsThe data regarding visits to the rheumatologist and prosthetic surgery of patients with in Spain is similar to most studies published in our environment, however, other aspects concerning the use of health resources are different compared to other countries. This data may help to understand and improve organizational aspects of management of SA in Spanish hospitals.
