Co-Development of Educational Aspirations and Academic Burnout from Adolescence to Adulthood in Finland
2017
The study followed 871 participants from age 17 to 25. Resources were related to lower cynical attitude towards studying and feelings of inadequacy, whereas demands were related to all three components of academic burnout. Family resources predicted higher educational aspirations. Co-development between educational aspirations and academic burnout showed that among those on the vocational track, the more exhaustion they felt, the higher their aspirations, which again increased their exhaustion. Among those on the academic track, the less cynicism they felt, the higher their aspirations which again decreased their cynicism. High aspirations positively and cynicism negatively predicted educat…
Immunoperoxidase Staining of Fine-Needle Aspiration Biopsies of Renal Cell Carcinoma Using Tumor-Specific Monoclonal Antibody
1987
In 30 nephrectomy specimens, fine needle aspiration biopsies (FNAB) were performed both in the tumor and in the macroscopically normal part of the kidney: 18 were well differentiated renal cell carcinoma (RCC), 6 were moderately differentiated RCC, 4 were poorly differentiated RCC, and 2 were oncocytomas. FNAB was also performed in a bone metastasis of RCC. FNAB materials were stained using the immunoperoxidase method with RCC-specific monoclonal antibody and were compared with the staining of frozen sections. In all cases where tumor-antigen expression could be demonstrated in the frozen sections, a FNAB had already proven positive. There were only 2 false-negative cases where sufficient c…
Intraductal aspiration: a promising new tissue-sampling technique for the diagnosis of suspected malignant biliary strictures
2012
Brushing is the most commonly used technique for biliary sampling at ERCP, despite its limited sensitivity. To evaluate intraductal aspiration (IDA) as a new combined endoscopic technique for cytodiagnosis, its cellular adequacy, diagnostic accuracy for cancer detection, feasibility, and safety. Prospective, observational study. Single tertiary referral center. IDA cellular adequacy, diagnostic accuracy for cancer detection, feasibility, and safety. From April 2009 to September 2010, 42 consecutive patients with suspected malignant biliary stricture underwent ERCP, with tissue sampling obtained with IDA. IDA included performance of standard brushing in all patients. After standard brushing,…
German Survey on EUS-Guided Diagnosis and Management of Gastrointestinal Stromal Tumors (GISTs) - Evidence or "Gut-Feeling"?
2015
To examine practice patterns of endosonographers in diagnosing and managing gastrointestinal stromal tumors (GISTs) in Germany.A modified published survey (Ha et al., Gastrointest Endosc 2009) was sent to endosonographic ultrasound (EUS) customers in Germany. The survey was also publicized on the homepage of an EUS interest group. To avoid duplicate opinions, participants were asked to return one survey per institution.142 centers of roughly 850 German EUS centers responded. 25 % were from University hospitals and 74 % from community hospitals. 61 % performed 2 EUS scans for suspected subepithelial lesions/week. Although 97 % of respondents believed that tissue acquisition with CD117 immuno…

Zakrzepica zatok żylnych — diagnostyka, leczenie farmakologiczne i alternatywne leczenie endowaskularne z zastosowaniem systemów do trombektomii
2018
Cel: Celem artykułu jest omówienie patofizjologii, obrazu klinicznego, neuroobrazowania zakrzepicy żył mózgowych oraz nowoczesnych metod leczenia, z uwzględnieniem leczenia endowaskularnego. Metody: Na podstawie dostępnego piśmiennictwa przeanalizowano wyniki leczenia farmakologicznego oraz alternatywnego postępowania endowaskularnego, obecnie wciąż zarezerwowanego dla chorych bez odpowiedzi lub z nieadekwatną odpowiedzią na leczenie farmakologiczne przeciwkrzepliwe. Wyniki: Objawy kliniczne zakrzepicy zatok żylnych są często niespecyficzne i wymagają dokładnej diagnostyki neurologicznej i obrazowej. Jest to o tyle istotne, że zakrzepica zatok żylnych występuje rzadko, dotyczy głównie młody…
Diagnostic performance of endoscopic ultrasound through‐the‐needle microforceps biopsy of pancreatic cystic lesions: Systematic review with meta‐anal…
2020
Objectives Endoscopic ultrasound through-the-needle biopsy (EUS-TTNB) is a useful tool for differential diagnosis among pancreatic cystic lesions (PCLs). Cystic fluid cytology (CFC) is recommended by guidelines, but its diagnostic accuracy is about 50%. The aim of this meta-analysis is to assess the clinical impact of EUS-TTNB in terms of technical success (TS), histological accuracy (HA) and diagnostic yield (DY). Methods Original studies in English language on EUS-TTNB were searched in MEDLINE and EMBASE until October 2019. Diagnostic accuracy of EUS-TTNB for identification of mucinous PCLs was calculated using individual diagnostic data of patients who underwent CFC and surgery. Results …
PERCUTANEOUS US (ULTRA SOUND) GUIDED FINE NEEDLE ASPIRATION (FNA) OF ENDOTHORACIC NEOPLASM
2022
Introduction: Ultrasound (US)-guided fine needle aspiration (FNA) of percutaneous, transparietal endothoracic lesions, is a useful method in the diagnostic process for anatomopathological characterization. This sampling is a minimally invasive procedure, with a low complication rate and can be performed under loco-regional anesthesia Material and methods: We retrospectively studied (2009 to 2019) the utility of US guided transthoracic FNA in the diagnosis of suspected endothoracic lesions on 54 patients (34 men and 20 women), aged between 44 and 79 years, with pleural, pulmonary or mediastinal neoplasm viewable with an US examination. Results: The definitive diagnosis of malignant or benign…
Les parcours scolaires des enfants issus de l'immigration : réussites et désillusions
2006
06052; Cette communication propose une analyse des parcours scolaires des enfants issus de l'immigration en lien avec les aspirations éducatives de leurs parents et le vécu de ces parcours par les enfants eux-mêmes. Les données exploitées sont celles du Panel 95-2002 (DEP, Ministère de l'Education) et de l'enquête Education et famille (INSEE, 2003). Sont mises en évidence les aspirations éducatives plus élevées des familles immigrées comparées aux familles françaises d'origine de même milieu social, avec des différences selon l'origine géographique. Ces aspirations jouent un rôle positif sur les scolarités des enfants d'immigrés. Toutefois, existent des décalages entre aspirations et parcou…
