Development of ELIP to Assess Physical Literacy for Emerging Adults: A Methodological and Epistemological Challenge.

Purpose: Following increased interest in physical literacy (PL), development of appropriate tools for assessment has become an important next step for its operationalization. To forward the development of such tools, the objective of this study was to build the foundations of the Évaluation de la Littératie Physique (ELIP), designed to help reduce existing tensions in approaches to PL assessment that may be resulting in a low uptake into applied settings. Methods: We followed two steps: (1) the development of the first version of ELIP by deploying a Delphi method (n = 30); and (2) the modification of items through cognitive interviews with emerging adults (n = 32). Results: The expert consensus highlighted four dimensions of PL to be assessed-physical; affective; cognitive; and social-with new perspectives, including a preference for broad motor tests over fitness. Conclusion: Results offer new insights into the assessment of emerging adults' PL, but ELIP still requires further work concerning validity, reliability, and sensitivity.

Bioactive phenols in algae: the application of pressurized-liquid and solid-phase extraction techniques.

A new extraction technique based on the off-line combination of pressurized-liquid with solid-phase extraction (PLE-SPE) is described. The method was used for the extraction of bioactive phenolic acids (protocatechuic, p-hydroxybenzoic, 2,3-dihydroxybenzoic, chlorogenic, vanillic, caffeic, p-coumaric, salicylic acid), cinnamic acid and hydroxybenzaldehydes (p-hydroxybenzaldehyde, 3,4-dihydroxybenzaldehyde, vanillin) from in vitro culture of two freshwater algae (Anabaena doliolum and Spongiochloris spongiosa) and from food products of marine macroalgae Porphyra tenera (nori) and Undaria pinnatifida (wakame). For the identification and quantification of the compounds the molecular ions [M-H](-) and specific fragments were analyzed by quadrupole mass spectrometry analyzer connected on-line with a reversed-phase HPLC system. Our analysis showed that the freshwater algae and marine algal products contained submicrogram or microgram level of above-mentioned phenols per gram of lyophilized sample. In addition, the total phenol content (Folin-Ciocalteu assay) and antioxidant activity (TEAC assay, Trolox equivalent antioxidant capacity assay) of the PLE-SPE extracts were determined and discussed.

[Our concept of defecography. Methods and reproducibility of results]. / Defekografie v nasem pojetí. Metoda a reprodukovatelnost výsledku.

Defecography is used in the Czech Republic only exceptionally. Since 1988 the authors made 402 defecographic examinations. They submit a detailed description of hitherto assembled experience and their own modification of the examination. As contrast material they use at present Micropaque susp. thickened by means of wheat bran. They administer it by means of a modified press for dough preparation. The X-rays are taken on a modified ordinary stool made from soft timber. For screening of uncovered places in the visual field they use individually placed copper plates 2 mm thick. For better evaluation of the X-rays the authors place during examination an X-ray contrasting net behind the patient. Pictures are taken at rest, during contraction, during modified Valsalva's manoeuvre and during all stages of defecation. The authors mention the most interesting pathological pictures they encountered so far--internal prolapse, levator hernia, rectocele, sphincter defect, various forms of prolapses and dyskineses of the pelvic floor. In the authors opinion the basic quantifiable parameters are the magnitude of the anorectal angles. They used the assessment method described by Mahieu, as well as the mediorectal angle which in their opinion is a reflection of the patient's somatotype and levator function. More than the absolute values of the angles they emphasize the difference of the two angles and change of the latter during contraction and defecation. In their opinion enlargement of the difference during contraction and diminution to values close to zero is normal. Converse values are according to the authors evidence of dyssynergy of the pelvic floor. Independent assessment of the angles and magnitude of the lift of the pelvic floor by three subjects are subjected to statistical analysis. They provide evidence of complete reproducibility of results of anorectal angles according to the authors' definition. The results of assessment can be used to investigate relations with parameters of anorectal manometry (AM) or transrectal sonographyy (TRS) in subsequent investigations.

Recent position of transjugular intrahepatic portosystemic shunt in the treatment of portal hypertension.

Transjugular intrahepatic portosystemic shunt (TIPS) is a side-to-side portocaval shunt for threatening complications of portal hypertension. TIPS effectively decreases portal hypertension connecting the hepatic and portal vein with an expandable metal stent without the mortality and morbidity of an open surgical procedure. Technical success can be achieved in over 90% of patients, with procedure related mortality of 1-2%. The main problem is stenosis or occlusion of the shunt by neo-intimal hyperplasia narrowing the lumen of the shunt in 20-80% of patients during 6-12 months, but fortunately, most stenotic stents can be revised successfully. Recent indications for TIPS are acute variceal hemorrhage refractory to endoscopic treatment and recurrent variceal bleeding despite sclerotherapy or band ligation. TIPS insertion in the treatment of refractory ascites seems to be promising.

[Transjugular intrahepatic portosystemic shunt in the treatment of complications in portal hypertension]. / Transjugulární intrahepatická portosystémová spojka v lécbe komplikací portální hypertenze.

Transjugular intrahepatic portosystemic shunt (TIPS) is a side-to-side portocaval shunt for threatening complications of portal hypertension. The purpose of this study was to evaluate in first 33 patients indicated for TIPS insertion in our institution the efficacy, complications, and mortality. Indication was failure of sclerotherapy or ligation in control either of acute (n = 4) or repetitive (n = 25) variceal bleeding and refractory ascites (n = 4). The technical success rate was with 70% (21/30) lower than expected, but the complication rate was also very low. There were no fatal complications, only one subcapsular liver hematome, and in one patient repetitive punction of biliary tract. The 30-days mortality was 10% (2/21) and rebleeding was 15% (3/20), caused always by thrombosis of the shunt. TIPS seems to be a promising therapeutic procedure after failed endoscopic therapy of esophageal varices without the mortality and morbidity of an open surgical procedure. Recent indications for TIPS are acute variceal hemorrhage refractory to endoscopic treatment and recurrent variceal bleeding despite sclerotherapy or band ligation. Promising seems to be TIPS insertion in the treatment of refractory ascites.
