Using Dancesport as an Educational Resource for Improving Institutionalized Children's Learning Strategies.

INTRODUCTION: Specialized studies mention that extracurricular activities (including dance) contribute to the stimulation of multiple intelligences, on whose development the educational process and academic success depend. The aims of the study were to investigate the benefits of dancesport for the development of institutionalized children's learning strategies, and to examine gender-dependent differences in learning strategies, as well as to formulate possible recommendations regarding the practice of dance at the age of preadolescence, from the perspective of school success vectors. METHODS: Through the School Motivation and Learning Strategies Inventory (SMALSI), we could observe the changes produced in children from the initial phase to the final assessment at the end of a dancesport program. The intervention took place over a period of six months with a frequency of two lessons per week, with each lesson lasting 60 min, and aimed to increase school motivation and performance, considering the learning strategies used by institutionalized children. Thirty institutionalized children, aged 11-12 years old, participated in the research, during which they did not engage in other extracurricular physical activities. The preadolescents were assessed using the School Motivation and Learning Strategies Inventory (SMALSI). This self-report rating scale measures nine areas associated with learning strategies, six of which focus on student strengths (study strategies, note-taking/listening skills, reading/comprehension strategies, writing/research skills, test-taking strategies, and time management/organization techniques), and three are aimed at student liabilities (low academic motivation, test anxiety, and concentration/attention difficulties). RESULTS: The results show that the biggest improvements in the case of institutionalized children were recorded for study strategies, effectiveness of test-taking strategies, and concentration difficulties. Girls registered significantly better results than boys only in the case of study strategies and for writing/research skills (Mann-Whitney test was used). DISCUSSION: The study demonstrates the benefits of dancesport practice for the development of institutionalized children's learning strategies, creating a foundation for the improvement of their academic performance and school integration. CONCLUSIONS: At the end of the dance program, significant improvements in academic interest were observed due to the testing strategies used. Better results were also obtained for the scales of anxiety and difficulty concentrating during tests, where average scores decreased significantly.

Evaluation of the pancreatic tumors by transabdominal Shear Wave Elastography: preliminary results of a pilot study.

AIM: To identify the mean values of Shear Wave Elastography (SWE) in pancreatic neoplasms. MATERIAL AND METHOD: This pilot case-control study was conducted in a tertiary care setting and data were collected in a prospective manner. Thirty-three subjects were included and divided into two groups: 18 healthy subjects and 15 patients with pancreatic neoplasm, from which 14 patients were diagnosed with adenocarcinoma and one with intraductal papillary mucinous neoplasia. Inclusion criteria for patients with pancreatic neoplasia were histopathological confirmation obtained by endoscopic ultrasonography (EUS) with fine needle aspiration or surgically and imaging confirmation by computed tomography with contrast enhancement. A number of minimum 5 shear wave velocity (SWV) measurements regarding each segment respectively at the tumoral level was obtained among a series of elastograms. RESULTS: The mean SWV of the pancreas in the control group was 1.21±0.27 m/s. Data regarding the pathological parenchyma indicated an increase of the SWV at the tumoral (cephalic) level corresponding to 1.54±0.32 m/s, with significant statistical difference between the control batch and tumoral group, p=0.02. CONCLUSIONS: Transabdominal SWE represents a surrogate but feasible method for differentiation cancer from the normal pancreatic tissue. In a clinical setting, data regarding the stiffness complementary to an ultrasound evaluation could guide high-risk patients for a close-up pancreatic monitoring.

Prevalence and associated risk factors of non-alcoholic fatty liver disease in hospitalized patients.

BACKGROUND AND AIM: Non-alcoholic fatty liver disease (NAFLD) and metabolic syndrome (MS) have become important health issues in many countries. There is increasing interest in ultrasound-diagnosed NAFLD. The aim of the study was to evaluate the prevalence of NAFLD in hospitalized patients and to determine the metabolic features of ultrasound-diagnosed patients. METHODS: A number of 3,005 hospitalized patients were prospectively assessed. Subjects were submitted to a standard interview and a chart review was made to note anthropometric (BMI and waist circumference), biochemical and abdominal ultrasonography parameters. MS was evaluated according to IDF criteria. Logistic regression analysis was used to identify independent factors associated with ultrasound-diagnosed NAFLD. RESULTS: The prevalence of NAFLD in the enrolled subjects was 20%. Patients with NAFLD had higher values of BMI and waist circumference. MS was present in 61.09 % of cases with NAFLD. At least one risk factor was observed in 88.41%, and in 14.07% of patients all 5 criteria were fulfilled. The odds ratios of the metabolic disorders in subjects with NAFLD compared with those without NAFLD were higher in the overweight and obese group than in the normal-weight group. Central obesity, hypertriglyceridemia, and elevated blood pressure (for total and the overweight group) were independently associated with NAFLD. CONCLUSION: The prevalence of ultrasound NAFLD in hospitalized patients was similar to the general population. NAFLD was closely associated with metabolic disorders.

Staging of portal hypertension and portosystemic shunts using dynamic nuclear medicine investigations.

AIM: To explore portal hypertension and portosystemic shunts and to stage chronic liver disease (CLD) based on the pathophysiology of portal hemodynamics. METHODS: Per-rectal portal scintigraphy (PRPS) was performed on 312 patients with CLD and liver angioscintigraphy (LAS) on 231 of them. The control group included 25 healthy subjects. We developed a new model of PRPS interpretation by introducing two new parameters, the liver transit time (LTT) and the circulation time between right heart and liver (RHLT). LTT for each lobe was used to evaluate the early portal hypertension. RHLT is useful in cirrhosis to detect liver areas missing portal inflow. We calculated the classical per-rectal portal shunt index (PRSI) at PRPS and the hepatic perfusion index (HPI) at LAS. RESULTS: The normal LTT value was 24 +/- 1 s. Abnormal LTT had PPV = 100% for CLD. 27 non-cirrhotic patients had LTT increased up to 35 s (median 27 s). RHLT (42 +/- 1 s) was not related to liver disease. Cirrhosis could be excluded in all patients with PRSI < 5% (P < 0.01). PRSI > 30% had PPV = 100% for cirrhosis. Based on PRPS and LAS we propose the classification of CLD in 5 hemodynamic stages. Stage 0 is normal (LTT = 24 s, PRSI < 5%). In stage 1, LTT is increased, while PRSI remains normal. In stage 2, LTT is decreased between 16 s and 23 s, whereas PRSI is increased between 5% and 10%. In stage 3, PRSI is increased to 10%-30%, and LTT becomes undetectable by PRPS due to the portosystemic shunts. Stage 4 includes the patients with PRSI > 30%. RHLT and HPI were used to subtype stage 4. In our study stage 0 had NPV = 100% for CLD, stage 1 had PPV = 100% for non-cirrhotic CLD, stages 2 and 3 represented the transition from chronic hepatitis to cirrhosis, stage 4 had PPV = 100% for cirrhosis. CONCLUSION: LTT allows the detection of early portal hypertension and of opening of transhepatic shunts. PRSI is useful in CLD with extrahepatic portosystemic shunts. Our hemodynamic model stages the evolution of portal hypertension and portosystemic shunts. It may be of use in the selection of patients for interferon therapy.

Endoscopic mucosal resection for early esophageal cancer. A case report.

With the rapid progress of the diagnostic techniques, especially endoscopy, the discovery rate of early superficial cancer of the esophagus has increased markedly. Relatively recently introduced, endoscopic mucosal resection (EMR) is now widely used in the treatment of early stage cancer of the esophagus. We used EMR in the case of a patient who was incidentally diagnosed with a type IIa early esophageal cancer using a band-ligating device. We had no serious complications. At the histopathological examination we noticed that the carcinoma involved the upper third of the submucosal layer. For this reason the patient was given additional therapy (radiotherapy), too. A month after the EMR, at the histological examination we found no local signs of recurrent disease.
