Factors influencing the level of stigma in Parkinson’s disease in western Turkey
Background and purpose – Stigma is
a widespread phenomenon in Parkinson’s
disease (PD) and has been shown to affect
the quality of life of individuals. This study
aims to assess the level of stigma and
identify the factors contributing to stigma in
patients with PD in Turkey.
Methods – A total of 142 patients diagno
sed with PD between June 2022 and
March 2023 were included in the study.
Sociodemographic data including age,
gender, marital status, education level,
and duration of PD were collected using a
sociodemographic information form. Mo
tor symptom severity was assessed using
the Unified Parkinson’s Disease Rating
Scale (UPDRS part III). The disease stage
was determined using the Hoehn and Yahr
scale. Participants were classified as PIGD
(postural instability/gait difficulty) or TD
(tremor dominant) based on the UPDRS
score. Patients with a UPDRS ratio greater
than or equal to 1.5 were classified as TD,
while subjects with a ratio less than or
equal to 1.0 were classified as PIGD. Ratios
between 1.0 and 1.5 were classified as
mixed type. Depression was assessed us
ing the Hamilton Depression Rating Scale
(HAM-D), while stigma was measured using
the Chronic Illness Anticipated Stigma
Scale (CIASS) and the stigma sub-scale of
the 39 item Parkinson’s Disease Question
naire (PDQ-39 stigma sub-scale).
Results – The mean score on the stigma
sub-scale of the PDQ-39 was 7.60±4.39,
while the mean total stigma score on the
CIASS was 1.37±0.39. Our results indicated
that stigma was more prevalent among
patients with PD with the TD motor subtype,
younger age, shorter disease duration,
higher level of disability, and presence of
depression symptoms. Conclusion – Our study highlights the asso
ciation between stigma and disease progres
sion, duration, and depressive symptoms in
patients with PD in western Turkey. | Háttér és cél – A Parkinson kórban (PD)
szenvedők gyakran találkoznak előítélettel és
szembesülnek stigmatizálással, ami bizonyí
tottan rontja életminőségüket. E tanulmány
célja a stigmatizáltság szintjének felmérése,
és a stigmához hozzájáruló tényezők azono
sítása törökországi PD-betegek körében.
Módszerek – A vizsgálatba összesen 142,
2022 júniusa és 2023 márciusa között Par
kinson-kórral diagnosztizált beteget vontunk
be. A szociodemográfiai adatokat, köztük
az életkort, a nemet, a családi állapotot, az
iskolai végzettséget és a PD időtartamát egy
szociodemográfiai adatlap segítségével gyűj
töttük össze. A motoros tünetek súlyosságát
a Mozgászavar Társaság-féle Egyesített Par
kinson-kór Pontozó Skála (UPDRS III. rész) se
gítségével értékeltük. A betegség stádiumát
a Hoehn–Yahr-skála segítségével határoztuk
meg. A résztvevőket az UPDRS-pontszám
alapján PIGD (posturalis instabilitás/járási
nehézség) vagy TD (tremordomináns) kate
góriába soroltuk. Az 1,5-nél nagyobb vagy
azzal egyenlő UPDRS-aránnyal rendelkező
betegeket TD-nek, míg az 1,0-nél kisebb vagy
azzal egyenlő arányúakat PIGD-nek minősí
tettük. Az 1,0 és 1,5 közötti aránnyal bírókat
vegyes típusba soroltuk. A depressziót a
Hamilton Depresszió Pontozó Skála (HAM-D),
míg a stigmát a Krónikus Betegségekben
Anticipált Stigma Skála (CIASS) és a 39 tételes
Parkinson-kór Kérdőív stigmaalskálája (PDQ-
39 stigmaalskála) segítségével mértük.
Eredmények – A PDQ-39 stigmaalskála
átlagos pontszáma 7,60 ± 4,39 volt, míg a
CIASS teljes stigmapontszámának átlaga
1,37 ± 0,39 volt. Eredményeink azt mutat
ják, hogy a stigma gyakoribb a TD motoros
altípusú, fiatalabb, rövidebb betegségtar
tamú, nagyobb fokú fogyatékossággal élő
és a depressziós tünetekkel rendelkező
PD betegekkel szemben. Következtetés – Tanulmányunk rávilágít a
stigmatizáltság és a betegség progressziója,
időtartama és a depressziós tünetek közötti
összefüggésre a nyugat-törökországi PD-
betegek körében

Entrepreneurial Universities in Times of Crisis: Case of Covid-19 Pandemic
Entrepreneurial universities are at the centre of innovation ecosystems, and play a critical role in improving them. The concept of the quintuple helix, which deals with the interrelations between universities, industries, governments, societies and environments is highly sensitive to the role of entrepreneurial universities which could pave the way for their success. During the COVID-19 pandemic, they faced several challenges, and the ecosystem needed their attention to a greater extent. This research highlights the main challenges faced by entrepreneurial universities and their responses to those challenges. Hence, qualitative research was conducted by interviewing twenty-five experts from different countries in the Middle East, including Iran, Turkey, Iraq, United Arab Emirates, Oman, Jordan, Kuwait, and Lebanon. The respondents were engaged in five online focus group sessions, and the findings were coded. The findings revealed the main challenges faced by entrepreneurial universities as well as their relevant potential responses.

Surface modification of stimuli responsive polymers by wrinkling method: surface morphology and bacterial adsorption studies
Stimuli responsive polymers are the great candidates to engineer the surfaces that can switch between different states of surface energy. Integration of those responsive polymers to the systems, where filtration or a controlled adsorption of the microscopic organisms are targeted, offers a very practical and functional pathway. Topographical modifications of these polymers may improve the wettability limits of the smart surfaces and the control over the adhesion of microscopic organisms. In this work, we present a useful method to form 2 distinct sets of surface modified thin films: Poly(Nisopropylacrylamide) [PNIPAAm] and poly(hydroxyethylmethacrylate-coperfluorodecylacrylate) [poly(HEMA-co-PFA)]. Surface modifications of the thin films are achieved by the initiated chemical vapor deposition (iCVD) of the polymers on stretched poly(dimethylsiloxane) (PDMS) molds in order to provide simultaneous chemical and morphological treatment. The surface properties of the flat and wrinkled thin films are analyzed. Wrinkled PNIPAAm surfaces are also investigated for bacterial attachment activity
Maximizing the number of worker’s self-selected tasks in spatial crowdsourcing
ABSTRACT With the progress of mobile devices and wireless broadband, a new eMarket platform, termed spatial crowdsourcing is emerging, which enables workers (aka crowd) to perform a set of spatial tasks (i.e., tasks related to a geographical location and time) posted by a requester. In this paper, we study a version of the spatial crowdsourcing problem in which the workers autonomously select their tasks, called the worker selected tasks (WST) mode. Towards this end, given a worker, and a set of tasks each of which is associated with a location and an expiration time, we aim to find a schedule for the worker that maximizes the number of performed tasks. We first prove that this problem is NP-hard. Subsequently, for small number of tasks, we propose two exact algorithms based on dynamic programming and branch-and-bound strategies. Since the exact algorithms cannot scale for large number of tasks and/or limited amount of resources on mobile platforms, we also propose approximation and progressive algorithms. We conducted a thorough experimental evaluation on both real-world and synthetic data to compare the performance and accuracy of our proposed approaches
Symptomatic Giant Cavernous Haemangioma of the Liver: Is Enucleation a Safe Method?
Twenty-three patients with symptomatic giant hemangioma of the liver were treated by surgery between 1979 and 1996 at the department of General Surgery, Faculty of Medicine, University of Çukurova. Twenty-three enucleations were performed in 21 patients, left lateral segmentectomy in one patient and enucleation plus left lobectomy in one patient. The tumors were enucleated along the interface between the hemangioma and normal liver tissue. The diameters of the tumors ranged from 5×5 to 25×15 cm. The mean blood loss for enucleations was 525 ml (range 500–1000 ml). There was no mortality and no postoperative bleeding. Three patients had postoperative complications. Enucleation is the best surgical technique for symptomatic giant hemangioma of the liver. It may be performed with no mortality, low morbidity and the preservation of all normal liver parenchyma
Patients with primary restless legs syndrome have higher prevalence of autonomic dysfunction and irritable bowel syndrome
CONCLUSION The presence of autonomic nervous system impairment in patients with pRLS and the strong link between IBS and pRLS merit further, more extensive investigation
Nitric oxide synthases in infants and children with pulmonary hypertension and congenital heart disease
Nitric oxide is an important regulator of vascular tone in the pulmonary circulation. Surgical correction of congenital heart disease limits pulmonary hypertension to a brief period. The study has measured expression of endothelial (eNOS), inducible (iNOS), and neuronal nitric oxide synthase (nNOS) in the lungs from biopsies of infants with pulmonary hypertension secondary to cardiac abnormalities (n = 26), compared to a control group who did not have pulmonary or cardiac disease (n = 8). eNOS, iNOS and nNOS were identified by immunohistochemistry and quantified in specific cell types. Significant increases of eNOS and iNOS staining were found in pulmonary vascular endothelial cells of patients with congenital heart disease compared to control infants. These changes were confined to endothelial cells and not present in other cell types. Patients who strongly expressed eNOS also had strong expression of iNOS. Upregulation of eNOS and iNOS occurs at an early stage of pulmonary hypertension, and may be a compensatory mechanism limiting the rise in pulmonary artery pressure
Существует ли связь между средним уровнем mIDkIne и прогнозом заболевания COVID-19?
The objective was aimed to measure plasma midkine (MK)* levels in patients with COVID-19 and assess its clinical significance. Materials and Methods. 88 patients observed in our hospital with a diagnosis of COVID-19 were included in the study. The patients’ demographic characteristics, clinical, and laboratory data were studied, and the relationship between MK levels, prognosis, and other parameters was investigated. Results. Of the 88 patients included in the study, 43 (48.9 %) were female and 45 (51.1%) were male. 24 (27%) patients died. The mean age of non-survivors was 70 ± 12.3 years and the survivors were 61.9 ± 18.2 years. Mortality predictors such as D-dimer, ferritin, troponin, LDH, CRP, and procalcitonin were significantly higher in non-survivors than in survivors (p < 0.05). The median MK level (IR) was 152.5 ± 125 pg/ml in all patients, 143 ± 149 pg/ml in survivors, and 165.5 ± 76 pg/ml in non-survivors (p = 0.546). The difference between these two groups was not statistically significant. The area under the ROC curve was found to be 0.542 (95% CI 0.423–0.661, p = 0.546). Conclusion. MK is not a biomarker that can replace or reinforce known predictors of mortality in COVID-19 patients. Цель. Исследование направлено на измерение уровня Midkine (MK)* в плазме крови у пациентов с COVID-19 и оценку его клинической значимости. Материалы и методы. В исследование включены 88 пациентов, наблюдавшихся в клинике с диагнозом COVID-19. Изучены демографические характеристики пациентов, клинические и лабораторные данные, а также исследована взаимосвязь между уровнями MK, прогнозом и другими параметрами. Результаты. Из 88 пациентов, включенных в исследование, 43 (48,9 %) были женщинами и 45 (51,1 %) – мужчинами. 24 (27 %) пациента умерли. Средний возраст невыживших составил 70 ± 12,3 года, а выживших – 61,9 ± 18,2 года. Предикторы смертности, такие как D-димер, ферритин, тропонин, ЛДГ, СРБ и прокальцитонин, были значительно выше у умерших, чем у выживших (р < 0,05). Медиана уровня МК (IR) составила 152,5 ± 125 пг/мл у всех пациентов, 143 ± 149 пг/мл у выживших и 165,5 ± 76 пг/мл у умерших (р = 0,546). Разница между этими 2 группами была незначима. Было обнаружено, что площадь под кривой ROC составляет 0,542 (95 % ДИ 0,423–0,661, р = 0,546). Вывод. МК не является биомаркером, который может заменить или усилить известные предикторы смертности у пациентов с COVID-19
