Marco Stella, Massimiliano Bissolati, Daniele Gentile, Alessandro Arriciati
Pancreaticoduodenectomy (PD) is one of the procedures in general surgery with the highest rate of life-threatening complications. The positive impact of the volume-outcome ratio on outcomes and mortality in pancreatic surgery (PS) has led to policy-level efforts toward centralization of care for PS that is currently under evaluation by some Regional Health Services. The role of the surgeon's experience and training is still under debate. The aim of this paper is to compare the outcomes of PS by the same surgeon in a high volume (HV) and in a low volume (LV) hospital to assess whether a specific training in PS could outdo the benefits of hospital volume...

REVIEW
Sitaramesh Emani
PURPOSE OF REVIEW: Rehospitalization for heart failure remains a challenge in the treatment of affected patients. The ability to remotely monitor patients for worsening heart failure may provide an avenue through which therapeutic interventions can be made to prevent a rehospitalization. Available data on remote monitoring to reduce heart failure rehospitalizations are reviewed within. RECENT FINDINGS: Strategies to reduce readmissions include clinical telemonitoring, bioimpedance changes, biomarkers, and remote hemodynamic monitoring...

In humans, ten genes encode small heat shock proteins with lens αA-crystallin and αB-crystallin representing two of the most prominent members. The canonical isoforms of αA-crystallin and αB-crystallin collaborate in the eye lens to prevent irreversible protein aggregation and preserve visual acuity. α-Crystallins form large polydisperse homo-oligomers and hetero-oligomers and as part of the proteostasis system bind substrate proteins in non-native conformations, thereby stabilizing them. Here, we analyzed a previously uncharacterized, alternative splice variant (isoform 2) of human αA-crystallin with an exchanged N-terminal sequence...

The purified BCP61 was reported to be a unique low-molecular-weight (MW) anti-microbial peptide because of its non-identical alanine-rich N-terminal sequence. In this study, we investigated the anti-inflammatory effects of BCP61 on induction of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), pro-inflammatory cytokines, nuclear factor-kappa B (NF-κB), and mitogen-activated protein kinases (MAPKs) in lipopolysaccharide (LPS)-stimulated Raw 264.7 cells. The treatment with BCP61, with varying concentrations of 10, 50, and 100 μg/mL, inhibited levels of expression of LPS-induced NF-κB and MAPKs (extracellular signal-related kinases (ERKs), c-Jun NH2-terminal kinase (JNK), and mitogen-activated protein (p38)) as well as production of pro-inflammatory mediators, such as nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6)...

Hyperglycemia and mitochondrial ROS overproduction have been identified as key factors involved in the development of diabetic nephropathy. This has encouraged the search for strategies decreasing glucose levels and long-term improvement of redox status of glutathione, the main antioxidant counteracting mitochondrial damage. Previously, we have shown that avocado oil improves redox status of glutathione in liver and brain mitochondria from streptozotocin-induced diabetic rats; however, the long-term effects of avocado oil and its hypoglycemic effect cannot be evaluated because this model displays low survival and insulin depletion...

Colonoscopy is an important diagnostic and screening tool for colorectal cancer detection and prevention, and adequate bowel preparation is critical for successful colonoscopy. Complications related to colonoscopy, either directly or indirectly related to the procedure, are increased in elderly patients, and the risks and benefits of colonoscopy procedures need to be carefully considered in these patients. Recent studies have shown that 4 L polyethylene glycol with a split preparation is safe and effective for elderly patients, and is the preferred preparation for patients with medical comorbidities...

Fiix-prothrombin time (Fiix-PT) differs from traditional PT in being affected by reduced factor (F) II or FX only. In the randomized controlled Fiix-trial, patients on warfarin monitored with Fiix-PT (Fiix-warfarin patients) had fewer thromboembolisms (TE), similar major bleeding (MB) and more stable anticoagulation than patients monitored with PT (PT-warfarin patients). In the current Fiix-trial report we analyzed how reduced anticoagulation variability during Fiix-PT monitoring was reflected in patients with TE or bleeding...

In the present study, the effects of low-molecular-weight organic acids (OAs) on the toxicity of copper (Cu) to the earthworm Eisenia fetida (E. fetida) were investigated in a simulated soil solution. We exposed E. fetida to soil solution containing Cu and a variety of OAs (acetic acid, oxalic acid, citric acid, and EDTA). We found that the addition of OAs reduced the toxicity of Cu to E. fetida, where the reduction was strongest in EDTA and weakest in acetic acid. These compounds decreased the mortality rate of E...

In this work, through a docking analysis of compounds from the ZINC chemical library on human β-tubulin using high performance computer cluster, we report new polycyclic aromatic compounds that bind with high energy on the colchicine binding site of β-tubulin, suggesting three new key amino acids. However, molecular dynamic analysis showed low stability in the interaction between ligand and receptor. Results were confirmed experimentally in in vitro and in vivo models that suggest that molecular dynamics simulation is the best option to find new potential β-tubulin inhibitors...

Drought-acclimated vines maintained higher gas exchange compared to irrigated controls under water deficit; this effect is associated with modified leaf turgor but not with improved petiole vulnerability to cavitation. A key feature for the prosperity of plants under changing environments is the plasticity of their hydraulic system. In the present research we studied the hydraulic regulation in grapevines (Vitis vinifera L.) that were first acclimated for 39 days to well-watered (WW), sustained water deficit (SD), or transient-cycles of dehydration-rehydration-water deficit (TD) conditions, and then subjected to varying degrees of drought...

The authors discuss the latest data regarding obesity and diabetes worldwide and in Italy. Two very important articles were recently published by the Non Communicable Disease Risk Factor Collaboration which employs hundreds of researchers around the world. The two articles respectively describe trends in Body Mass Index and diabetes, in different countries in the past 40 years, and show that there has been a startling increase in the number of obese people and people suffering from diabetes worldwide. The number of obese people (BMI>=30 Kg/m2) has risen globally from 105 million in 1975 to 641 million in 2014...

The aim of this observational descriptive study was to identify the main international models evaluating the quality of nursing homes for non self-sufficient elderly persons, and to apply them in the Italian health system. Firstly, a bibliographic search of institutional websites and Pubmed-Medline was performed to identify the main international models. Secondly, three variables were chosen to evaluate the level of implementability of the models: (1) frequency of use of quality indicators in the international models; (2) degree of constructability of the models in two Italian nursing homes; (3) perceived relevance of the indicators used by the chosen models, by nursing home workers...

BACKGROUND/AIMS: Osteogenic differentiation of mesenchymal stem cells (MSCs) plays a crucial role in bone regeneration and bone reparation. This complex process is regulated precisely and firmly by specific factors. Recent studies have demonstrated that miR-125b regulates osteogenic differentiation, but little is known about the molecular mechanisms of this regulation. Furthermore, how miR-125b regulates the osteogenic differentiation of MSCs still needs elucidation. METHODS: In the present study, human bone marrow-derived mesenchymal stem cells (hBMSCs) were isolated and induced to osteoblasts with miR-125b inhibition or overexpression...
