A post COVID lockdown pilot study on the effect of physical activity intensity on cognitive functions of children aged 6-8 years old
Physical activity practice is very important for individualâs wealth status. Moreover, it is possible to consider physical activity one of the teachersâ tool to improve the academic achievement and the cognitive functions in children. However, according to some evidences it seems that the physical activity at high intensity increase the cognitive functions compared to the low intensity physical activity. In this project, we investigate how the intensity of physical activity affects a series of cognitive functions such as Attention and Working Memory. Eleven participants of a summer camp participated at the study. Three experimental weeks with different physical intensities were involved (Standard Intensity, High intensity and Low Intensity). Participants performed the cognitive tasks at the beginning and at the end of each experimental week. Our results indicated an effect of the physical activity intensity in some kind of attention. Working Memory instead, was not affected. Thus, our results suggested that intensity could be an important factor to increase some cognitive functions, but not all of them

COVID-19 Pandemic Impact on Undergraduate Nursing Students: A Cross-Sectional Study
COVID-19 is a challenge for education systems around the world. This study aimed to evaluate the perceived impact of the COVID-19 pandemic on nursing students, by assessing their emotions, the level of concern in contracting the virus and their perceived stress. We conducted an observational cross-sectional study. A total of 709 nursing students completed an anonymous questionnaire. The levels of anxiety and stress were assessed using the generalized anxiety disorder scale and the COVID-19 student stress questionnaire, respectively. In total, 56.8% of the sample often or always found it difficult to attend distance-learning activities. The main difficulty referred to was connection problems (75.7%). The mean generalized anxiety disorder score was 9.46 (SD = 5.4) and appeared almost homogeneous among students across the three years of study; most of the students showed mild (35%) to moderate (27%) levels of anxiety; 19% had severe anxiety. The overall COVID-19 stressor mean scores were 11.40 (SD = 6.50); the majority of the students (47.1%) showed scores indicative of moderate stress, 25% showed low stress levels, and 28% showed high-stress levels. Improvements and investments are needed to ensure high-quality distance learning, adequate connectivity, technical support for students, as well as strategies to promote mental health
Complicated enterocele: timely resolution with bowel resection via a vaginal approach: case report
Background: Enterocele is an uncommon, serious condition that requires accurate and early diagnosis to prevent complications such as intestinal obstruction, incarceration, and strangulation, with consequent intestinal ischemia, necrosis, and evisceration. We report a rare case of a patient with a voluminous enterocele and initial signs of intestinal ischemia who underwent urgent vaginal surgery. Case description: An 80-year-old woman presented with a voluminous mass protruding from the vagina, associated abdominopelvic pain, a 10-day history of bowel sub-occlusion, and numerous episodes of profuse vaginal bleeding. She was diagnosed with an enterocele with early signs of complications. Owing to her advanced clinical condition and comorbidities, we opted for an urgent vaginal procedure. Intestinal loops with initial signs of ischemia were resected via a transvaginal approach, leading to good clinical outcomes. She was discharged on postoperative day 5. Conclusions: This rare case highlights a surgical emergency that was managed with transvaginal resection of the intestine. Early identification of the initial signs of complications allowed for this less invasive approach, resulting in reduced morbidity and length of hospital stay
The Impact of the COVID-19 Pandemic on Women's Perinatal Mental Health: Preliminary Data on the Risk of Perinatal Depression/Anxiety from a National Survey in Italy
Increasing evidence suggests that during the COVID-19 pandemic, anxiety and depression during the perinatal period increased. The aim of the study is to estimate the prevalence of risk for both maternal depression and anxiety among women attending 18 healthcare centres in Italy during the SARS-COV-2 pandemic and to investigate the psychosocial risks and protective factors associated. It was divided into a retrospective phase (2019, 2020, and the first nine months of 2021) and a prospective phase (which began in November 2021 and it is still ongoing), which screened 12,479 and 2349 women, respectively, for a total of 14,828 women in the perinatal period. To evaluate the risk of anxiety and depression, the General Anxiety Disorder-7 (GAD-7), the Edinburgh Postnatal Depression Scale (EPDS), and an ad hoc form were used to collect sociodemographic variables. In the prospective study, the average age of the women is 31 (range 18-52) years. Results showed that the percentage of women who had EPDS score â„9 increased from 11.6% in 2019 to 25.5% in the period ranging from November 2021 to April 2022. In logistic regression models, the variables associated with the risk of depression at a level â€0.01 include having economic problems (OR 2.16) and not being able to rely on support from relatives or friends (OR 2.36). Having the professional status of the housewife is a lower risk (OR 0.52). Those associated with the risk of anxiety include being Italian (OR 2.97), having an education below secondary school level (OR 0.47), having some or many economic problems (OR 2.87), being unable to rely on support from relatives or friends (OR 2.48), and not having attended an antenatal course (OR 1.41). The data from this survey could be useful to determine the impact of the SARS-COV-2 pandemic on women and to establish a screening program with common and uniformly applied criteria which are consistent with national and international women's mental health programs
Clinical and laboratory features associated with macrophage activation syndrome in Still's disease: data from the international AIDA Network Still's Disease Registry
: To characterize clinical and laboratory signs of patients with still's disease experiencing macrophage activation syndrome (MAS) and identify factors associated with MAS development. patients with still's disease classified according to internationally accepted criteria were enrolled in the autoInflammatory disease alliance (AIDA) still's disease registry. clinical and laboratory features observed during the inflammatory attack complicated by MAS were included in univariate and multivariate logistic regression analysis to identify factors associated to MAS development. A total of 414 patients with Still's disease were included; 39 (9.4%) of them developed MAS during clinical history. At univariate analyses, the following variables were significantly associated with MAS: classification of arthritis based on the number of joints involved (pâ=â0.003), liver involvement (pâ=â0.04), hepatomegaly (pâ=â0.02), hepatic failure (pâ=â0.01), axillary lymphadenopathy (pâ=â0.04), pneumonia (pâ=â0.03), acute respiratory distress syndrome (pâ<â0.001), platelet abnormalities (pâ<â0.001), high serum ferritin levels (pâ=â0.009), abnormal liver function tests (pâ=â0.009), hypoalbuminemia (pâ=â0.002), increased LDH (pâ=â0.001), and LDH serum levels (pâ<â0.001). at multivariate analysis, hepatomegaly (OR 8.7, 95% CI 1.9-52.6, pâ=â0.007) and monoarthritis (OR 15.8, 95% CI 2.9-97.1, pâ=â0.001), were directly associated with MAS, while the decade of life at Still's disease onset (OR 0.6, 95% CI 0.4-0.9, pâ=â0.045), a normal platelet count (OR 0.1, 95% CI 0.01-0.8, pâ=â0.034) or thrombocytosis (OR 0.01, 95% CI 0.0-0.2, pâ=â0.008) resulted to be protective. clinical and laboratory factors associated with MAS development have been identified in a large cohort of patients based on real-life data
Acute Delta Hepatitis in Italy spanning three decades (1991â2019): Evidence for the effectiveness of the hepatitis B vaccination campaign
Updated incidence data of acute Delta virus hepatitis (HDV) are lacking worldwide. Our aim was to evaluate incidence of and risk factors for acute HDV in Italy after the introduction of the compulsory vaccination against hepatitis B virus (HBV) in 1991. Data were obtained from the National Surveillance System of acute viral hepatitis (SEIEVA). Independent predictors of HDV were assessed by logistic-regression analysis. The incidence of acute HDV per 1-million population declined from 3.2 cases in 1987 to 0.04 in 2019, parallel to that of acute HBV per 100,000 from 10.0 to 0.39 cases during the same period. The median age of cases increased from 27 years in the decade 1991-1999 to 44 years in the decade 2010-2019 (p < .001). Over the same period, the male/female ratio decreased from 3.8 to 2.1, the proportion of coinfections increased from 55% to 75% (p = .003) and that of HBsAg positive acute hepatitis tested for by IgM anti-HDV linearly decreased from 50.1% to 34.1% (p < .001). People born abroad accounted for 24.6% of cases in 2004-2010 and 32.1% in 2011-2019. In the period 2010-2019, risky sexual behaviour (O.R. 4.2; 95%CI: 1.4-12.8) was the sole independent predictor of acute HDV; conversely intravenous drug use was no longer associated (O.R. 1.25; 95%CI: 0.15-10.22) with this. In conclusion, HBV vaccination was an effective measure to control acute HDV. Intravenous drug use is no longer an efficient mode of HDV spread. Testing for IgM-anti HDV is a grey area requiring alert. Acute HDV in foreigners should be monitored in the years to come
Multidifferential study of identified charged hadron distributions in -tagged jets in proton-proton collisions at 13 TeV
Jet fragmentation functions are measured for the first time in proton-proton
collisions for charged pions, kaons, and protons within jets recoiling against
a boson. The charged-hadron distributions are studied longitudinally and
transversely to the jet direction for jets with transverse momentum 20 GeV and in the pseudorapidity range . The
data sample was collected with the LHCb experiment at a center-of-mass energy
of 13 TeV, corresponding to an integrated luminosity of 1.64 fb. Triple
differential distributions as a function of the hadron longitudinal momentum
fraction, hadron transverse momentum, and jet transverse momentum are also
measured for the first time. This helps constrain transverse-momentum-dependent
fragmentation functions. Differences in the shapes and magnitudes of the
measured distributions for the different hadron species provide insights into
the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any
