Question: Right ventricular pacing (RVP) has been associated with heart failure and increased mortality. His-bundle pacing (HBP) is more physiological but requires a mapping catheter or a backup right ventricular lead and is technically challenging.', 'We sought to assess the feasibility, safety, and clinical outcomes of permanent HBP in an unselected population as compared to RVP.', 'All patients requiring pacemaker implantation routinely underwent attempt at permanent HBP using the Select Secure (model 3830) pacing lead in the year 2011 delivered through a fixed-shaped catheter (C315 HIS) at one hospital and RVP at the second hospital. Patients were followed from implantation, 2 weeks, 2 months, 1 year, and 2 years. Fluoroscopy time (FT), pacing threshold (PTh), complications, heart failure hospitalization, and mortality were compared.', 'HBP was attempted in 94 consecutive patients, while 98 patients underwent RVP. HBP was successful in 75 patients (80%). FT was similar (12.7 8 minutes vs 10 14 minutes; median 9.1 vs 6.4 minutes; P = .14) and PTh was higher in the HBP group than in the RVP group (1.35 0.9 V vs 0.6 0.5 V at 0.5 ms; P < .001) and remained stable over a 2-year follow-up period. In patients with >40% ventricular pacing (>60% of patients), heart failure hospitalization was significantly reduced in the HBP group than in the RVP group (2% vs 15%; P = .02). There was no difference in mortality between the 2 groups (13% in the HBP group vs 18% in the RVP group; P = .45).

Answer: Is permanent His-bundle pacing feasible , safe , and superior to right ventricular pacing in routine clinical practice?

Question: Inadequate response of the innate immune system to bacterial antigens present in the intestinal flora may play a role in the development of necrotizing enterocolitis (NEC). Pattern recognition receptors such as CD14, toll-like receptor (TLR) 4, and caspase-recruitment domain (CARD) 15 bind bacterial lipopolysaccharide and peptidoglycan, and their activation leads to production of inflammatory cytokines. Our aim was to evaluate whether single nucleotide polymorphisms (SNPs) of CD14, TLR4, and CARD15 are associated with the risk of NEC in very low birth weight (VLBW) infants.', 'We determined the CD14 C-260T, TLR4 A +896G, C +1196T, and CARD15 G +2722C, C +2104T, 3020insC functional SNPs in dried blood samples from 118 VLBW infants (of those, 41 developed NEC) and from 146 healthy term newborns using polymerase chain reaction and restriction fragment length polymorphism methods. We tested the association between genotype and risk of NEC.', 'No significant differences were found in the prevalence of CD14 -260T, TLR4 +896G, +1196T, and CARD15 +2722C, +2104T, 3020insC alleles between VLBW infants and healthy term newborns (P = NS). The frequencies of investigated genotypes were similar in infants with and without NEC (P = NS). Furthermore, we did not find any association between genotype and prematurity or sepsis, which are important risk factors of NEC.

Answer: Are genetic polymorphisms of CD14 , toll-like receptor 4 , and caspase-recruitment domain 15 associated with necrotizing enterocolitis in very low birth weight infants?

Question: Most patients with Fusarium infection present with affection of the tegumentary system, with the presence of necrotic and/or inflammatory lesions associated with pain.', 'To evaluate the effect of the intradermal application of a metabolic extract of Fusarium oxysporum in the skin of Wistar rats.', 'The extract was obtained from fungal cultivation in Czapek-Dox medium. It was sterilized by filtration through a Millipore membrane, and injected (0.5 mg/mL) intradermally into the skin of rats, which were killed 3, 6, 12, and 24 h after inoculation. Skin specimens were placed in paraffin and stained using hematoxylin and eosin, and toluidine blue, for the evaluation of the inflammatory response, and Sirius red for the quantification of collagen. Terminal deoxynucleotidyl transferase-mediated UTP nick end labelling (TUNEL) was used for the identification of apoptosis. Tissue reactions were graded and compared over time and compartment.', 'The inflammatory reaction reached a peak at 12 h for both the dermis and subcutaneous region, being graded as moderate and moderate to severe, respectively. There was an influx of granulocytes, lymphocytes, and macrophages. A significant increase in the number of mast cells, as well as the presence of hyperemic vessels and apoptotic bodies, was observed. There was TUNEL staining in keratinocytes, fibroblasts, endothelial cells, muscles, and in the cells of the inflammatory infiltrate. There was a significant decrease in the area occupied by collagen after 12 h.

Answer:
Does metabolic extract of Fusarium oxysporum induce histopathologic alterations and apoptosis in the skin of Wistar rats?
