A Case Series Report on the Effect of Tofacitinib on Joint Inflammation and Gut Microbiota Composition in Psoriatic Arthritis Patients Naive to Biologic Agents.

Introduction: Psoriatic arthritis (PsA) is a complex condition within the Spondyloarthritis (SpA) group. Recent studies have focused on the important role of the intestinal microbiota in maintaining immunological homeostasis, highlighting how intestinal dysbiosis may act as a trigger for autoimmune diseases. Tofacitinib is a Janus kinase inhibitor (JAK-i) with proven efficacy for the treatment of both rheumatoid arthritis and PsA.

Resistant starch from high-amylose maize increases insulin sensitivity in overweight and obese men.

This study evaluated the effects of 2 levels of intake of high-amylose maize type 2 resistant starch (HAM-RS2) on insulin sensitivity (S(I)) in participants with waist circumference ≥89 (women) or ≥102 cm (men). Participants received 0 (control starch), 15, or 30 g/d (double-blind) of HAM-RS2 in random order for 4-wk periods separated by 3-wk washouts. Minimal model S(I) was assessed at the end of each period using the insulin-modified i.

Relation between estimates of cornstarch digestibility by the Englyst in vitro method and glycemic response, subjective appetite, and short-term food intake in young men.

Background: Starch composition and rate of digestion are determinants of blood glucose concentrations and food intake (FI).

Objective: Our objective was to describe relations between estimates of digestibility of starches by the in vitro Englyst method and their effect on blood glucose concentrations, subjective appetite, and FI in young men.

Design: Subjects consumed 5 soups containing 50 g maltodextrin, whole-grain, high-amylose, regular cornstarch, or no added starch at 1-wk intervals.

Prevalence of home artificial nutrition in Italy in 2005: a survey by the Italian Society for Parenteral and Enteral Nutrition (SINPE).

Aim: To determine the prevalence (cases per million inhabitants) of home artificial nutrition (HAN), enteral (HEN) and parenteral (HPN), in Italy, grouped according to administrative regions, patient age and primary disease, and to analyze the impact both of the presence of an HAN regional regulation and of demographic characteristics.

Methods: In April 2005, the Regional Coordinators of the Italian Society for Parenteral and Enteral Nutrition (SINPE) recorded all the ongoing cases of HAN using a structured questionnaire and were asked to estimate the representativeness of the collected sample with respect to the total expected HAN.

Results: A total of 6955 cases of HAN (93.

Conformational study of proteins by SAXS and EDXD: the case of trypsin and trypsinogen.

The radius of gyration (Rg) of bovine trypsinogen and beta-trypsin was measured by an energy-dispersive X-ray technique (EDXD) and by small-angle X-ray scattering (SAXS), under different solvent conditions. Both techniques gave superimposable results. The experimental evidence demonstrated that: (1) no structural modifications and/or damage occurred during the data acquisition by EDXD; (2) at pH 4 the active enzyme has one class of chloride binding sites in common with the zymogen, whereas the latter protease shows an additional class able to reverse the effects on Rg induced by chloride at low concentration; and (3) the pH profile of the Rg of both proteases does not resemble at all the pH effect on beta-trypsin activity, a result in line with the finding that the electrical potentials induced by surface charge are small in absolute magnitude and produce no gradient across the active site.

Safety and factors related to survival after percutaneous endoscopic gastrostomy in ALS. ALS Percutaneous Endoscopic Gastrostomy Study Group.

Percutaneous endoscopic gastrostomy (PEG) has been proposed as symptomatic treatment of dysphagia in patients with ALS. Safety and factors related to survival after PEG were analyzed in 50 consecutive ALS patients. No major acute or long-term complications were observed.

[Trace nutrients in total enteral nutrition: the basal status and longitudinal course].

Introduction: Previous studies demonstrated deficiencies of selenium and other micronutrients in patients receiving total enteral nutrition (TEN). The content and bioavailability of trace elements in enteral formulas can be suboptimal.

Material And Methods: Basal blood levels of some trace elements (copper, iron, selenium, zinc) and vitamins (B12, folic acid) were determined in twenty patients at the beginning of TEN.

[Percutaneous endoscopic gastrostomy].

Surgical gastrostomies were first performed in the middle of the 19th century and modified during the following years, but the most important technical improvement was percutaneous endoscopic placement (PEG), in 1980 by Ponsky and Gauderer. This technique doesn't require anesthesia and it in possible also in patients with contraindications to surgical gastrostomy. The simple procedure involves a shorter hospitalization, lower risks and reduced costs.

[Enteral nutrition in the elderly].

Elderly is particularly at risk of malnutrition: he is not able to feed himself adequately, it is then important to attain correct intakes using also artificial enteral nutritional techniques (nasogastric tube, gastrostomy, etc.). These techniques may lead to complications (ab ingestis pneumonia, metabolic complications, alvus disorders): the use of artificially nutrition in the elderly must be carefully evaluated.

Sterol Oxides in Foodstuffs: A Review.

The toxicological significance of oxidized cholesterol has been well documented in numerous studies. This review focuses on the analysis of dietary sterol oxides in the foodstuffs examined to date with particular emphasis on isolation and characterization techniques. Eight common oxidation products of cholesterol have been identified in certain cholesterol-rich foods subjected to oxidative stress during food processing and/or storage.
