On multivalued weakly Picard operators in partial Hausdorff metric spaces
2015
We discuss multivalued weakly Picard operators on partial Hausdorff metric spaces. First, we obtain Kikkawa-Suzuki type fixed point theorems for a new type of generalized contractive conditions. Then, we prove data dependence of a fixed points set theorem. Finally, we present sufficient conditions for well-posedness of a fixed point problem. Our results generalize, complement and extend classical theorems in metric and partial metric spaces.
The assessment of skeletal status in young patients with Turner syndrome by 2 densitometric techniques: Phalangeal quantitative ultrasound and dual e…
2018
Background. Studies using dual energy X-ray absorptiometry (DXA) demonstrate a reduction in bone mineral density (BMD) in children and adolescents with Turner syndrome (TS). However, these studies do not take into account changes in bone size, which influence BMD in the case of short-statured patients. Phalangeal quantitative ultrasound (phQUS) measurements have shown an ability to reveal changes due to skeletal growth, aging, and bone and mineral disorders. There is limited data on bone mineral status in girls with TS assessed by 2 different techniques, i.e., DXA and phQUS. Objectives. The aim of this study was to investigate the potential negative impact of TS on bone status and to assess…
Analysis of the impact of sex and age on the variation in the prevalence of antinuclear autoantibodies in Polish population: a nationwide observation…
2022
AbstractThe detection of antinuclear autoantibody (ANA) is dependent on many factors and varies between the populations. The aim of the study was first to assess the prevalence of ANA in the Polish adult population depending on age, sex and the cutoff threshold used for the results obtained. Second, we estimated the occurrence of individual types of ANA-staining patterns. We tested 1731 patient samples using commercially available IIFA using two cutoff thresholds of 1:100 and 1:160. We found ANA in 260 participants (15.0%), but the percentage of positive results strongly depended on the cutoff level. For a cutoff threshold 1:100, the positive population was 19.5% and for the 1:160 cutoff th…
Presence of Serum Antinuclear Antibodies Does Not Impact Long-Term Outcomes in Nonalcoholic Fatty Liver Disease
2020
Introduction We investigated the longitudinal impact of antinuclear antibody (ANA) on clinical outcomes and survival in nonalcoholic fatty liver disease (NAFLD). Methods ANA were found in 16.9% of 923 biopsy-proven NAFLD patients, but none of them had histologic autoimmune hepatitis (AIH) or developed AIH after a mean follow-up of 106±50 months. Results Although ANA-positive cases had a higher prevalence of nonalcoholic steatohepatitis at baseline, the occurrence of liver-related events, hepatocellula carcinoma, cardiovascular events, extrahepatic malignancy, and overall survival were similar to ANA-negative. Discussion Once AIH has been ruled out, the long-term outcomes and survival are un…
Frequency and Correlates of Mild Cognitive Impairment in Myasthenia Gravis
2023
Background: Antibodies against acetylcholine receptors (AChRs) can also target nicotinic AChRs that are present throughout the central nervous system, thus leading to cognitive dysfunctions in patients with myasthenia gravis (MG). However, the presence of cognitive impairment in MG is controversial, and the factors that may influence this risk are almost completely unknown. In this study, the frequency of mild cognitive impairment (MCI) in MG, as well as the clinical, immunological, and behavioral correlates of MCI in MG were evaluated. Methods: A total of 52 patients with MG underwent a comprehensive assessment including motor and functional scales, serological testing, and neuropsychologi…
Towards a typology of negative engagement behavior in social media
2022
Extant literature on consumer engagement has focused on positive manifestations of the construct, rather than on its negative dimension. Yet, many brand interactions are negative in nature. The purpose of this conceptual study is to develop a typology of negative engagement behavior in social media by using the multi-grounded theory (MGT) approach on a sample of 12,429 tweets extracted from Twitter. The analysis shows that negative engagement behavior with a brand or service provider as the object focus or target can be categorized according to (a) the manifestation of the negative engagement and (b) the emotional intensity of the negative engagement. Four categories of negative engagement …
Etiological factors of chronic hepatitis in Italy: a 2014 national survey.
2017
Background The last Italian prevalence survey on chronic hepatitis (CH) conducted in 2001 showed that the hepatitis C virus (HCV) was the main agent associated with CH. Aim The aim of this study was to evaluate epidemiological changes in CH occurring after 13 years. Patients and methods Enrollment of 1392 CH consecutive patients referred to 16 Italian liver units in 2014 scattered all over the country (four in the North, four in the Center, four in the South, and four in the Islands) was performed. Results The mean age of the patients was 58.3 years, with a sex ratio (male/female) of 1.5. HCV infection (also with other etiologies) continues to be the most prevalent etiology (58.1%). However…
Pilnvarojuma juridiskā spēka tiesiskie aspekti.
2022
Bakalaura darba “Pilnvarojuma juridiskā spēka tiesiskie aspekti” galvenais uzdevums ir apzināt problēmas, kas saistītas ar pilnvarojuma nodibināšanas un izmantošanas iespējām dažādās civiltiesisko attiecību situācijās, tostarp arī komerctiesību, kā arī personu iespējām izdot Latvijas Republikas tiesību sistēmai atbilstošu un par derīgu atzīstamu pilnvaru viņu interešu pārstāvībai, atrodoties ārpus Latvijas Republikas robežām, kā arī ārvalstīs izdoto pilnvaru atbilstības un piemērošanas iespēju problemātiku, darījumiem Latvijas Republikā. Vienlaicīgi, darbā tiek pētīts jautājums, kā tiesību piemērotājs, īpaši zvērināts notārs, var pārliecināties par ārvalstīs izdotas pilnvaras atbilstību pār…
Akomodācijas un verģences sistēmas darbības traucējumu izplatība Azerbaidžānā
2020
Maģistra darb ir uzrakstīts angļu valodā uz 35 lpp. Tas satur 19 tabulas, 2 pielikumus un 16 atsauces uz literatūras avotiem. Maģistra darba mērķis ir izvērtēt akomodācijas un verģences traucējumu izplatību un veidus Azerbaidžānas galvaspilsētas baku studentu vidū. Pētījumā piedalījās 192 dalībnieki (15-36 g.v.). Visiem tika veikta bezmaksas redzes pārbaude, kur detalizēti tika izvērtēta refrakcija, akomodācija un verģence. Rezultāti parāda, ka 51 ± 4 % dalībniekiem novēro dažāda veida akomodācijas un verģences darbības traucējumus vai to kombinācijas. Visbiežāk novērotās problēmas ir akomodācijas ekscess un konverģences nepietiekamība. Netiek novērota dzimuma un vecuma ietekme uz akomodāci…
