Postural evaluation in young skaters: effect of two proprioceptive training

The roller skating involves developing of motor and artistic skills from an early age. The aim was to evaluate the effects that an ocular a podalic proprioceptive training cause to postural control and stability in a sample of young skaters. A total of 25 skaters aged between 9 and 15 (12±2.14) divided into two groups: the eyes group (EG) aimed at exercising visual proprioception, the feet group (FG) aimed at exercising podalic proprioception. The participants were subject to through electronic stabilometry in static mode, open (OE) and closed (CE) eyes, in a time T0 (pre-training) and T1 (post-training), without and with skates. The results through the two paired t-test showed that both variables Wz (TotHz) to CE within the EG (p<.05) and Wx (TotHz) to CE within the FG (p<.05) were statistical significance. The unpaired t-test showed that the FG obtained a greater statistical significance than the EG for the VarVit and Wx (TotHz) variables in CE (p<.05) and Wz (TotHz) in both CE and OE (p<.05). The two-way ANOVA found statistical significance (p<.05) on the Wx (TotHz) variable in open/closed eyes of the FG (T0/T1). We concluded that in roller skating it could be useful to integrate athletic training with a visual proprioceptive training.

Peer victimization in Primary School. Gender difference

Purpose: The peer victimization is frequent phenomenon in the school. The aim of study was to investigate the gender distinction in the peer victimization, also considering the role that physical activity inside and outside school could have in this phenomenon. Methods: The study included 277 students (142 females; 134 males), between the ages of 8 and 10, attending the primary school. A questionnaire based on "Multi-dimensional Peer-Victimization Scale (MPVS)'' (Mynard et al., 2000), Italian version (Scarpa et al, 2010) and adapted to the age of the subjects, was given, to evaluate four areas of victimization (physical victimization, verbal victimization, social manipulation and attack on property). In addition, subjects were asked which physical activities they practiced in and out of school. Results: The results showed that the phenomenon victimization is present in a content way, and that males are more involved than females. Physical victimization falls more in the male gender (average value of 2±1.4 and 1.6±0.9 for the males and females, respectively), while the social manipulation in the women gender (average value of 1.9±1.2 and 1.7±1.1 for the females and males, respectively). The correlation between two or more macro-areas is there for the 74.32% of the cases and verbal victimization is the most widespread phenomenon in our sample (9.46%). The extra-school physical activity is performed by the majority of students (83.57%). Conclusions: The results confirm existing studies in the literature. The peer victimization includes not only being the obvious target of physical attacks but also includes more subtle forms of abuse, falling more in females behavior than in males

EDUCAZIONE MOTORIA E MIGLIORAMENTO DELLA DISPONIBILITÀ ATTENTIVA IN ETÀ EVOLUTIVA

L’Obbiettivo del presente lavoro è di verificare l’ipotesi secondo la quale una seduta psicomotoria condotta prima di un compito didattico (nel caso lo svolgimento di un dettato), possa incrementare la disponibilità attentiva in alunni di età compresa tra i 7 e gli 8 anni e la qualità del risultato al compito stesso. A tal fine sono stati coinvolti 170 alunni, ai quali si sono somministrati due diversi tipi di intervento: una prova di dettato (D) e una prova di dettato preceduta da una seduta di ginnastica (Ex+D). Successivamente, si è proceduto al calcolo degli errori compiuti nelle diverse prove e alle verifiche statistiche. Dall’analisi dei dati è emerso che la MEDIA degli errori compiuti nei dettati è inferiore e statisticamente significativa (p<0.0005) quando questi sono preceduti da una seduta di ginnastica psicomotoria rispetto a quando effettuati senza alcun intervento. In conclusione si è osservato che la pratica psicomotoria è da considerarsi, a tutti gli effetti, una buona opportunità per stimolare la disponibilità attentiva e migliorare le prestazioni didattiche e ciò ci fa pronunciare, senza indugio, l’esortazione affinché essa possa divenire prassi consueta in ambiente scolastico

Fate of Salmonella enterica Typhimurium and Listeria monocytogenes in Black Soldier Fly (Hermetia illucens) Larvae Reared on Two Artificial Diets

Ensuring food security is one of the main challenges facing the world over the next 30 years. There is, thus, an urgent need to significantly increase the supply of sustainable protein that can be transformed into animal feed. Proteins from insects offer a valuable alternative. This article presents the results of challenge tests conducted to investigate the dynamics of the microbial load of Salmonella enterica Typhimurium and Listeria monocytogenes in black soldier fly (Hermetia illucens) larvae grown on contaminated substrates. Four separate challenge tests were performed on two substrates: the Gainesville diet and a homemade diet. The challenge test procedure was carried out in accordance with ISO/DIS 20976-2 (under development). The results of this study show that, when grown on contaminated substrates, BSF larvae do not eliminate Salmonella Typhimurium or L. monocytogenes, but can reduce their microbial load. Sanitation processes downstream of the breeding of BSF larvae are, however, required to reduce the microbiological risks of this novel food

Nutritional status in post SARS-Cov2 rehabilitation patients

After prolonged hospitalization, the assessment of nutritional status and the identification of adequate nutritional support is of paramount importance. In this observational study, we aimed at assessing the presence of a malnutrition condition in SARS-Cov2 patients after the acute phase and the effects of a multidisciplinary rehabilitation program on nutritional and functional status

A randomized trial of tranexamic acid in combination with cell salvage plus a meta-analysis of randomized trials evaluating tranexamic acid in off-pump coronary artery bypass grafting

ObjectivesWe sought to evaluate the effectiveness of tranexamic acid in off-pump coronary artery bypass grafting surgery, either when used in combination with mechanical cell salvage or when used alone.MethodsOne hundred patients were randomized to either 2 g of tranexamic acid as an intravenous bolus before sternotomy or to placebo. Intraoperative and postoperative cell salvage was used in all patients. The primary end point was early postoperative blood loss (within 4 hours). To evaluate the efficacy of tranexamic acid in isolation, we also performed a meta-analysis of 4 randomized trials identified from a systematic literature search. The primary end point of the meta-analysis was red cell transfusion.ResultsIn our randomized trial patients in the tranexamic acid group had a significant reduction in early postoperative blood loss, (median difference, 50 mL; 95% confidence interval, 15-100 mL; P < .01); however, there was no reduction in the frequency of blood component transfusion. Patients in the placebo group received a significantly larger volume of autotransfused red cells (median difference, 120 mL; 95% confidence interval, 0-220 mL; P = .02). The meta-analysis demonstrated a significant reduction in red cell transfusions in patients receiving tranexamic acid compared with those receiving placebo (risk ratio, 0.48; 95% confidence interval, 0.24-0.97; P = .041). There was also a reduction in the frequency of any allogeneic blood component transfusion, as well as a highly significant reduction in postoperative blood loss, in patients receiving tranexamic acid (P < .001).ConclusionsTranexamic acid reduces blood loss and transfusion requirements in off-pump coronary artery bypass grafting surgery. A reduction in allogeneic blood transfusion was not evident in the presence of perioperative cell salvage. These data support the routine use of tranexamic acid in off-pump coronary artery bypass grafting surgery

Time Series Modelling with MATLAB: the SSpace toolbox

SSpace is a MATLAB toolbox for State-Space modeling that provides the user with tools for linear Gaussian, nonlinear, and non-Gaussian systems with the most advanced and up-to-date features available in any State-Space framework. Great flexibility is achieved because each model is coded on a standard MATLAB function, thence having absolute control on particular parameterizations, parameter constraints, time variation of parameters or variances, arbitrary nonlinear relations with inputs, time aggregation, nested models, system concatenation, etc. The toolbox may be used by specifying State-Space systems from scratch or by using ready-to-use templates for standard methods (like VARMAX, exponential smoothing, unobserved components, Dynamic Linear Regression, etc.). The toolbox is freely available via a public code repository with full documentation and help system. This chapter demonstrates the toolbox’s potential with several examples

The effect of seasoning with herbs on the nutritional, safety and sensory properties of reduced-sodium fermented Cobrançosa cv. table olives

This study aimed at evaluating the effectiveness of seasoning Cobrancosa table olives in a brine with aromatic ingredients, in order to mask the bitter taste given by KCl when added to reduced-sodium fermentation brines. Olives were fermented in two different salt combinations: Brine A, containing 8% NaCl and, Brine B, a reduced-sodium brine, containing 4% NaCl + 4% KCl. After the fermentation the olives were immersed in seasoning brines with NaCl (2%) and the aromatic herbs (thyme, oregano and calamintha), garlic and lemon. At the end of the fermentation and two weeks after seasoning, the physicochemical, nutritional, organoleptic, and microbiological parameters, were determined. The olives fermented in the reduced-sodium brines had half the sodium concentration, higher potassium and calcium content, a lower caloric level, but were considered, by a sensorial panel, more bitter than olives fermented in NaCl brine. Seasoned table olives, previously fermented in Brine A and Brine B, had no significant differences in the amounts of protein (1.23% or 1.11%), carbohydrates (1.0% or 0.66%), fat (20.0% or 20.5%) and dietary fiber (3.4% or 3.6%). Regarding mineral contents, the sodium-reduced fermented olives, presented one third of sodium, seven times more potassium and three times more calcium than the traditional olives fermented in 8% NaCl. Additionally, according to the panelists' evaluation, seasoning the olives fermented in 4% NaCl + 4% KCl, resulted in a decrease in bitterness and an improvement in the overall evaluation and flavor. Escherichia coli and Salmonella were not found in the olives produced.info:eu-repo/semantics/publishedVersio
