Environmental and health-related external costs of meat consumption in Italy: estimations and recommendations through life cycle assessment
The literature on the external costs of food consumption is limited. This study aims at advancing in this field by translating the environmental and health-related impacts generated by the life-cycle of meat into external costs via monetization. The main types of meat consumed in Italy are used as a case study. The potential external costs are estimated via attributional life cycle assessment (LCA), using: i) the ReCiPe method for the environmental impact assessment (fourteen impact categories), ii) the population attributional fractions for the health damage from meat ingestion, and iii) the CE Delft environmental prices for monetization. Results show that processed pork and beef generate the highest costs on society, with an external cost of approximately 2€ per 100 g. Fresh pork and poultry follow, with a cost of 1€ and 0.5€ per 100 g, respectively. For comparison, the potential external costs of legumes (i.e., a plant-based alternative to meat) are estimated to be from eight to twenty times lower than meat (around 0.05€ per 100 g of legumes). In 2018, meat consumed in Italy potentially generated a cost on society of 36.6 bn€. The burden arises almost equally from impacts generated before meat ingestion (mainly associated with the emissions arisen from farming), and after the ingestion (due to diseases potentially associated with meat consumption). A sensitivity analysis on the main parameters revealed a large uncertainty on the final yearly cost, ranging from 19 to 93 bn€. Although more research is needed to improve the accuracy and the validity of the models used in the study (e.g., human health impact assessment, monetization) and to include potential external costs currently unaccounted for (e.g., water use, animal welfare, occupational health), results show unequivocal significant costs associated with meat consumption. We thus advocate for policies aimed at reducing these costs and allocating them properly

A Simple fMRI Compatible Robotic Stimulator to Study the Neural Mechanisms of Touch and Pain.
This paper presents a simple device for the investigation of the human somatosensory system with functional magnetic imaging (fMRI). PC-controlled pneumatic actuation is employed to produce innocuous or noxious mechanical stimulation of the skin. Stimulation patterns are synchronized with fMRI and other relevant physiological measurements like electroencephalographic activity and vital physiological parameters. The system allows adjustable regulation of stimulation parameters and provides consistent patterns of stimulation. A validation experiment demonstrates that the system safely and reliably identifies clusters of functional activity in brain regions involved in the processing of pain. This new device is inexpensive, portable, easy-to-assemble and customizable to suit different experimental requirements. It provides robust and consistent somatosensory stimulation, which is of crucial importance to investigating the mechanisms of pain and its strong connection with the sense of touch
Strong and auxiliary forms of the semi-Lagrangian method for incompressible flows
We present a review of the semi-Lagrangian method for advection-diusion and incompressible Navier-Stokes equations discretized with high-order methods. In particular, we compare the strong form where the departure points are computed directly via backwards integration with the auxiliary form where an auxiliary advection equation is solved instead; the latter is also referred to as Operator Integration Factor Splitting (OIFS) scheme. For intermediate size of time steps the auxiliary form is preferrable but for large time steps only the strong form is stable
No evidence of association between genetic variants of the PDCD1 ligands and SLE

Please click on the hyperlink in Additional Links fieldPDCD1, an immunoreceptor involved in peripheral tolerance has previously been shown to be genetically associated with systemic lupus erythematosus (SLE). PDCD1 has two ligands whose genes are located in close proximity on chromosome 9p24. Our attention was drawn to these ligands after finding suggestive linkage to a marker (gata62f03, Z=2.27) located close to their genes in a genome scan of Icelandic families multiplex for SLE. Here, we analyse Swedish trios (N=149) for 23 single nucleotide polymorphisms (SNPs) within the genes of the PDCD1 ligands. Initially, indication of association to eight SNPs was observed, and these SNPs were therefore also analysed in Mexican trios (N=90), as well as independent sets of patients and controls from Sweden (152 patients, 448 controls) and Argentina (288 patients, 288 controls). We do not find support for genetic association to SLE. This is the first genetic study of SLE and the PDCD1 ligands and the lack of association in several cohorts implies that these genes are not major risk factors for SLE.Genes and Immunity (2007) 8, 69-74. doi:10.1038/sj.gene.6364360; published online 30 November 2006
2017 WSES and SICG guidelines on acute calcolous cholecystitis in elderly population 11 Medical and Health Sciences 1103 Clinical Sciences
Background: Gallstone disease is very common afflicting 20 million people in the USA. In Europe, the overall incidence of gallstone disease is 18.8% in women and 9.5% in men. The frequency of gallstones related disease increases by age. The elderly population is increasing worldwide. Aim: The present guidelines aims to report the results of the World Society of Emergency Surgery (WSES) and Italian Surgical Society for Elderly (SICG) consensus conference on acute calcolous cholecystitis (ACC) focused on elderly population. Material and methods: The 2016 WSES guidelines on ACC were used as baseline; six questions have been used to investigate the particularities in elderly population; the answers have been developed in terms of differences compared to the general population and to statements of the 2016 WSES Guidelines. The Consensus Conference discusses, voted, and modified the statements. International experts contributed in the elaboration of final statements and evaluation of the level of scientific evidences. Results: The quality of the studies available decreases when we approach ACC in elderly. Same admission laparoscopic cholecystectomy should be suggested for elderly people with ACC; frailty scores as well as clinical and surgical risk scores could be adopted but no general consensus exist. The role of cholecystostomy is uncertain. Discussion and conclusions: The evaluation of pro and cons for surgery or for alternative treatments in elderly suffering of ACC is more complex than in young people; also, the oldest old age is not a contraindication for surgery; however, a larger use of frailty and surgical risk scores could contribute to reach the best clinical judgment by the surgeon. The present guidelines offer the opportunity to share with the scientific community a baseline for future researches and discussion
focus groups in migration research a forum for public thinking
This chapter outlines how to use focus groups (FGs) in migration studies, considering this method a forum for "public thinking" and discussing controversial issues. Moreover, the use of FGs allows us to understand the process of creating consensus and dissent via interaction. The chapter is structured in five sections: the first one introduces what FGs are and why they are useful for migration research; the second focuses on how to build the groups and how to do comparative migration research with FGs; the third illustrates how to prepare and to facilitate group discussion, and how to ask questions and engage participants in collaborative migration research; the fourth introduces how to interpret discussions and how to analyse the everyday naturalization of nation, ethnicity and race; the final section discusses how to communicate FG results. Each section is devoted to a specific methodological issue and it includes at least one "box" with an example from European migration research
Pelvic trauma : WSES classification and guidelines
Complex pelvic injuries are among the most dangerous and deadly trauma related lesions. Different classification systems exist, some are based on the mechanism of injury, some on anatomic patterns and some are focusing on the resulting instability requiring operative fixation. The optimal treatment strategy, however, should keep into consideration the hemodynamic status, the anatomic impairment of pelvic ring function and the associated injuries. The management of pelvic trauma patients aims definitively to restore the homeostasis and the normal physiopathology associated to the mechanical stability of the pelvic ring. Thus the management of pelvic trauma must be multidisciplinary and should be ultimately based on the physiology of the patient and the anatomy of the injury. This paper presents the World Society of Emergency Surgery (WSES) classification of pelvic trauma and the management Guidelines.Peer reviewe
Outcomes following small bowel obstruction due to malignancy in the national audit of small bowel obstruction
Introduction
Patients with cancer who develop small bowel obstruction are at high risk of malnutrition and morbidity following compromise of gastrointestinal tract continuity. This study aimed to characterise current management and outcomes following malignant small bowel obstruction.
Methods
A prospective, multicentre cohort study of patients with small bowel obstruction who presented to UK hospitals between 16th January and 13th March 2017. Patients who presented with small bowel obstruction due to primary tumours of the intestine (excluding left-sided colonic tumours) or disseminated intra-abdominal malignancy were included. Outcomes included 30-day mortality and in-hospital complications. Cox-proportional hazards models were used to generate adjusted effects estimates, which are presented as hazard ratios (HR) alongside the corresponding 95% confidence interval (95% CI). The threshold for statistical significance was set at the level of P ≤ 0.05 a-priori.
Results
205 patients with malignant small bowel obstruction presented to emergency surgery services during the study period. Of these patients, 50 had obstruction due to right sided colon cancer, 143 due to disseminated intraabdominal malignancy, 10 had primary tumours of the small bowel and 2 patients had gastrointestinal stromal tumours. In total 100 out of 205 patients underwent a surgical intervention for obstruction. 30-day in-hospital mortality rate was 11.3% for those with primary tumours and 19.6% for those with disseminated malignancy. Severe risk of malnutrition was an independent predictor for poor mortality in this cohort (adjusted HR 16.18, 95% CI 1.86 to 140.84, p = 0.012). Patients with right-sided colon cancer had high rates of morbidity.
Conclusions
Mortality rates were high in patients with disseminated malignancy and in those with right sided colon cancer. Further research should identify optimal management strategy to reduce morbidity for these patient groups
