Towards addressing the need for novel alternatives to antibiotics, we attempted to sensitize Gram-negative bacilli (GNB) to innate antibacterial protagonists. We report a lipopeptide-like sequence (C10OOc12O) that inflicted outer-membrane damages at low micromolar range, whereas measurable bacterial growth inhibition in broth medium required >10-fold higher concentrations. In serum however, C10OOc12O induced antibacterial activity in a manner suppressible by anti-complements antibodies or heat treatment, and acted synergistically with exogenous lysozyme in broth and serum media...

Although pericardial effusion (PE) is common after cardiac surgery, late and recurrent cardiac tamponade that occurs more than 5-7 days after coronary artery bypass grafting is an infrequent complication. Moreover, the treatment of PE resistant to medical therapy, percutaneous drainage and pleuro-pericardial window remains a therapeutic challenge. We report the case of a recalcitrant PE with high-daily volume outflow drainage, finally treated with success, with a transdiaphragmatic pleuro-peritoneal shunting by laparoscopic approach...

Background.: Little is known regarding the optimal treatment of ventriculoperitoneal (VP) shunt infections in adults. Our aim was to assess the efficacy of treatment strategies and to identify factors that predict failure. Methods.: Retrospective, observational study of patients aged ≥12 years with VP shunt infections (1980 -2014). Therapeutic approaches were classified under 4 headings: only antibiotics (OA), one-stage shunt replacement (OSSR), two-stage shunt replacement (TSSR), and shunt removal without replacement (SR)...

Peritoneal dialysis (PD) is an effective renal replacement therapy, but a significant proportion of patients suffer PD-related complications, which limit the treatment duration. Mesothelial-to-mesenchymal transition (MMT) contributes to the PD-related peritoneal dysfunction. We analyzed the genetic reprograming of MMT to identify new biomarkers that may be tested in PD-patients. Microarray analysis revealed a partial overlapping between MMT induced in vitro and ex vivo in effluent-derived mesothelial cells, and that MMT is mainly a repression process being higher the number of genes that are down-regulated than those that are induced...

Bothrops envenomations can promote severe inflammatory responses by inducing edema, pain, leukocyte recruitment and release of chemical mediators by local cells. In the present study, two toxins from Bothrops atrox venom (the P-I metalloprotease Batroxase and the acidic phospholipase A2 BatroxPLA2) were evaluated in relation to their inflammatory effects induced in vivo and in vitro, mainly focusing on the participation of different immune cells and inflammatory mediators. Both toxins mainly promoted acute inflammatory responses with significant recruitment of neutrophils in the early hours (1-4h) after administration into the peritoneal cavity of C57BL/6 mice, and increased infiltration of mononuclear cells especially after 24h...

Colorectal cancer (CRC) remains the second leading cause of cancer-related deaths in the United States. While a decline has been observed in the older population, the occurrence of CRC in the adolescent and young adult (AYA) population has increased over the past two decades. The histopathologic characteristics and clinical behavior of CRC in AYA patients have been shown to be distinct from those of CRC in older adults. The rarer subtypes of CRC such as mucinous adenocarcinoma and signet-ring cell carcinoma are associated with a poorer prognosis compared to the more common subtypes...

Sepsis-typically caused by an uncontrolled and amplified host systemic inflammatory response to microbial infection-is a life-threatening complex clinical disorder and remains a major cause of infection-related deaths in the intensive care unit. Emerging evidence suggests that neuropilin 1 (Nrp1), an originally defined coreceptor for class 3 semaphorins and VEGF, plays important roles in the immune system; however, the function and regulation of macrophage Nrp1 in host immune defense against bacterial infection remain unknown...

REVIEW
Virendra R Desai, Robert A Scranton, Gavin W Britz
Subdural hematomas commonly recur after surgical evacuation, at a rate of 2% to 37%. Risk factors for recurrence can be patient related, radiologic, or surgical. Patient-related risk factors include alcoholism, seizure disorders, coagulopathy, and history of ventriculoperitoneal shunt. Radiologic factors include poor brain reexpansion postoperatively, significant subdural air, greater midline shift, heterogeneous hematomas (layered or multi-loculated), and higher-density hematomas. Surgical factors include lack of or poor postoperative drainage...

Chronic exposure to diets high in saturated fat (HFD) increases the prevalence of obesity and contributes to the development of low-grade inflammation and insulin resistance. A possible mediator accounting for obesity-associated inflammation and insulin resistance is Toll-like receptor 4 (TLR4). We investigated the role of adipocyte TLR4 in lipid and glucose homeostasis through an inducible, adipocyte-specific deletion of TLR4, the "TADIPO mouse". Consistent with a critical role for inflammation as a positive force for healthy adipose tissue expansion, chronic HFD exposure resulted in exacerbated whole body and muscle insulin resistance in the absence of TLR4 in the adipocyte...

In this project we examined how the presence of human peritoneal mesothelial cells (HPMCs) modifies (supports or inhibits) colorectal and pancreatic cancer cell progression in mice peritoneal cavity. Experiments were performed using primary, omentum-derived HPMCs, commercially available colorectal (SW-480) and pancreatic (PSN-1) cancer cells, and immunocompromised SCID mice. Tumor growth within the peritoneal cavity was monitored using bioluminescence. Adhesion of the cancer cells to HPMCs was examined using a fluorescence-based method, while the incidence of apoptosis was quantified using flow cytometry...
