The role of the Polish Constitution (Pre-2016) : development of the liberal democracy in European and international context
Why the Polish Supreme Court’s Reference on Judicial Independence to the CJEU is Admissible after all
On August 2nd 2018, the Polish Supreme Court has referred questions to the European Court of Justice about whether or not the forced retirement of most of its senior judges and other infringements of judicial independence are compatible with EU law. That decision is a landmark step in the serious constitutional crisis in Poland that has been going on for several years. One issue is of fundamental importance: Is the SC’s preliminary reference to the CJEU admissible
Though this be Madness, yet there’s Method in’t: Pitting the Polish Constitutional Tribunal against the Luxembourg Court

Molecular Patterns of Resistance Among Helicobacter pylori Strains in South-Western Poland
Treatment failure of Helicobacter pylori infection is caused mainly by progressive antibiotic resistance among H. pylori strains. In Poland, the prevalence of H. pylori strains resistant to metronidazole is higher than in other developed countries, reaching almost 50%, and resistance to clarithromycin is as high as 30% and is still increasing, contributing to the failure of first-line therapy in approximately 70% of patients. Moreover, the introduction of levofloxacin to eradication therapy of H. pylori infection quickly led to the emergence of resistant strains. Therefore, a necessary approach in microbiological diagnostics of H. pylori infection should be determination of susceptibility of H. pylori strains before the eradication treatment.Aim: In this study was to evaluate the molecular mechanisms of resistance among 170 H. pylori strains to clarithromycin, involving mutations in the 23S rRNA gene (A2143G, A2142G, A2143G) and to levofloxacin, involving mutations of gyrA and gyrB. Analysis was performed by using polymerase chain reaction and classical sequencing of DNA fragments.Results: Among examined strains, 26% were fully sensitive and 74% were resistant to at least one of the tested antibiotics. The overall resistance rate to metronidazole was as high as 56%, whereas to clarithromycin 46%, respectively. Resistance to LEV occurred among 6% of strains. All tested strains were susceptible to AMC and TET. The A2143G point mutation was found in 72% of clarithromycin-resistant strains. The most common mutation, present in 40% of H. pylori strains resistant to levofloxacin, was a change at position 91 of gyrA.Conclusion: The increasing number of point mutations in the 23S rRNA gene leads to an increase in the rates of antimicrobial resistance. Presence of the GCG allele at position 122 of the gyrA gene may cause an eightfold increase in risk of development of resistance to levofloxacin
Machine learning on the road to unlocking microbiota's potential for boosting immune checkpoint therapy
The intestinal microbiota is a complex and diverse ecological community that fulfills multiple functions and substantially impacts human health. Despite its plasticity, unfavorable conditions can cause perturbations leading to so-called dysbiosis, which have been connected to multiple diseases. Unfortunately, understanding the mechanisms underlying the crosstalk between those microorganisms and their host is proving to be difficult. Traditionally used bioinformatic tools have difficulties to fully exploit big data generated for this purpose by modern high throughput screens. Machine Learning (ML) may be a potential means of solving such problems, but it requires diligent application to allow for drawing valid conclusions. This is especially crucial as gaining insight into the mechanistic basis of microbial impact on human health is highly anticipated in numerous fields of study. This includes oncology, where growing amounts of studies implicate the gut ecosystems in both cancerogenesis and antineoplastic treatment outcomes. Based on these reports and first signs of clinical benefits related to microbiota modulation in human trials, hopes are rising for the development of microbiome-derived diagnostics and therapeutics. In this mini-review, we're inspecting analytical approaches used to uncover the role of gut microbiome in immune checkpoint therapy (ICT) with the use of shotgun metagenomic sequencing (SMS) data
Nutritional knowlegde and lifestyle of obese patients with diagnosed hypertension
Wstęp Celem pracy była ocena wiedzy żywieniowej
i wybranych elementów stylu życia otyłych pacjentów
ze zdiagnozowanym nadciśnieniem tętniczym,
leczonych w Klinice Chorób Zawodowych i Nadciśnienia
Tętniczego Szpitala Klinicznego Akademii
Medycznej we Wrocławiu.
Materiał i metody Badaniem objęto 52 osoby ze zdiagnozowanym
nadciśnieniem tętniczym - pacjentów
Kliniki Chorób Zawodowych i Nadciśnienia
Tętniczego Szpitala Klinicznego Akademii Medycznej
we Wrocławiu. Ankiety przeprowadzano od lutego
do maja 2008 roku. Do oceny wiedzy żywieniowej
i wybranych elementów stylu życia wykorzystano
autorski, standaryzowany kwestionariusz opracowany
w Zakładzie Żywienia Człowieka Uniwersytetu
Przyrodniczego we Wrocławiu. Obejmował
on różne zagadnienia, dotyczące między innymi rodzaju
aktywności fizycznej, częstości palenia papierosów.
Wyniki Wykonywanie ćwiczeń fizycznych trwających
jednorazowo 20-60 minut w czasie wolnym
od pracy zadeklarowało 85,7% kobiet oraz 74,2%
mężczyzn. Prawie 26% mężczyzn oraz 14% kobiet
nie wykonywało żadnych ćwiczeń fizycznych.
W niniejszej pracy oceniano również zawodową
aktywność fizyczną osób ankietowanych. Wśród
badanych 66,7% kobiet oraz 35,4% mężczyzn nie
pracowało zawodowo. Zapytani o dietę respondenci w większości odpowiadali, że nie stosują
żadnej. Takiej deklarację złożyło 66,7% kobiet
oraz aż 87,1% mężczyzn. Wysoki odsetek wskazuje,
że pacjenci nie stosują się do zaleceń dietetycznych
jako podstawowego elementu leczenia hipotensyjnego.
Wnioski Wiedzę żywieniową pacjentów z nadciśnieniem
tętniczym można uznać za zadowalającą. Niestety
w większości przypadków znajomość zasad
żywienia nie przekłada się na prawidłowe zachowania
żywieniowe.Background The study was aimed at evaluating the nutritional
knowledge and selected elements of lifestyle of
obese patients with diagnosed arterial hypertension.
Material and methods It covered 52 persons with diagnosed
arterial hypertension - patients of the Clinic
of Occupational Diseases and Arterial Hypertension,
Clinical Hospital of the Medical Academy in Wrocław,
and was conducted from February till May 2008. The
nutritional knowledge and selected elements of lifestyle
were evaluated by means of own-construct, standardized
questionnaire developed at the Chair of Human
Nutrition, Wrocław University of Life and Environmental
Sciences. It included questions from
different fields referring to knowledge on rational nutrition,
types of physical activity, frequency of cigarette
smoking, etc.
Results Physical activity lasting each time for 20-60 minutes
in free time was declared by 85.7% of the women and
by 74.2% of the men. Nearly 26% of the men and 14% of
the women did not perform any physical exercises. In the
reported survey, evaluation included also patients’ occupational
physical activity. Amongst the respondents surveyed,
66.7% of the women and 35.4% of the men did not
work. When asked about applying therapeutic diet, in most cases the patients replied that they did not use any
diet. Such replies were delivered by 66.7% of the women
and by as many as 87.1% of the men. The high percentage
of such answers indicates that the patients do not
comply with dietetic recommendations as the basic element
of the hypotensive therapy.
Conclusions The nutritional knowledge of the patients
with arterial hypertension may be evaluated as satisfactory.
Unfortunately, in most of the cases the knowledge of principles
of nutrition does not translate into proper nutritional
behaviors
Oncogenic osteomalacia — detection of the tumour site upon physical examination
Ostemalacja onkogenna jest rzadkim zespołem paranowotworowym wynikającym z obecności guza produkującego fosfatoniny. Pacjenci bez właściwej diagnozy i leczenia cierpią na silne bóle kości, nawracające patologiczne złamania i osłabienie mięśni przez miesiące, a nawet lata. Guz jest zwykle niewielki i może występować w różnych miejscach. Najczęstszym typem nowotworu powodującego onkogeniczną osteomalację jest wariant mezenchymalny w tkankach miękkich. Nasze badanie ma na celu przedstawianie przypadku klinicznego 50-letniej pacjentki z onkogeniczną osteomalacją u której w badaniu fizykalnym znaleźliśmy guz w tkance podskórnej okolicy prawej łopatki, co skróciło czas wdrożenia odpowiedniego leczenia do jednego tygodnia. Na tym przykładzie chcielibyśmy podkreślić rolę badania fizykalnego jako ważnego etapu w procesie diagnostycznym tej rzadkiej choroby i zalecić usuwanie łatwo dostępnych guzów bez przeprowadzania zaawansowanych badań obrazowych jako szybkie, skuteczne i korzystne ekonomicznie postępowanie.Not required for Clinical Vignette
Arrested neural and advanced mesenchymal differentiation of glioblastoma cells-comparative study with neural progenitors
<p>Abstract</p> <p>Background</p> <p>Although features of variable differentiation in glioblastoma cell cultures have been reported, a comparative analysis of differentiation properties of normal neural GFAP positive progenitors, and those shown by glioblastoma cells, has not been performed.</p> <p>Methods</p> <p>Following methods were used to compare glioblastoma cells and GFAP+NNP (NHA): exposure to neural differentiation medium, exposure to adipogenic and osteogenic medium, western blot analysis, immunocytochemistry, single cell assay, BrdU incorporation assay. To characterize glioblastoma cells <it>EGFR </it>amplification analysis, LOH/MSI analysis, and <it>P53 </it>nucleotide sequence analysis were performed.</p> <p>Results</p> <p><it>In vitro </it>differentiation of cancer cells derived from eight glioblastomas was compared with GFAP-positive normal neural progenitors (GFAP+NNP). Prior to exposure to differentiation medium, both types of cells showed similar multilineage phenotype (CD44+/MAP2+/GFAP+/Vimentin+/Beta III-tubulin+/Fibronectin+) and were positive for SOX-2 and Nestin. In contrast to GFAP+NNP, an efficient differentiation arrest was observed in all cell lines isolated from glioblastomas. Nevertheless, a subpopulation of cells isolated from four glioblastomas differentiated after serum-starvation with varying efficiency into derivatives indistinguishable from the neural derivatives of GFAP+NNP. Moreover, the cells derived from a majority of glioblastomas (7 out of 8), as well as GFAP+NNP, showed features of mesenchymal differentiation when exposed to medium with serum.</p> <p>Conclusion</p> <p>Our results showed that stable co-expression of multilineage markers by glioblastoma cells resulted from differentiation arrest. According to our data up to 95% of glioblastoma cells can present <it>in vitro </it>multilineage phenotype. The mesenchymal differentiation of glioblastoma cells is advanced and similar to mesenchymal differentiation of normal neural progenitors GFAP+NNP.</p
Age-dependent determinants of infectious complications profile in children and adults after hematopoietic cell transplantation : lesson from the nationwide study
Incidence and outcome of microbiologically documented bacterial/viral infections and invasive fungal disease (IFD) in children and adults after hematopoietic cell transplantation (HCT) were compared in 650 children and 3200 adults in multicenter cross-sectional nationwide study. Infections were diagnosed in 60.8% children and 35.0% adults, including respectively 69.1% and 63.5% allo-HCT, and 33.1% and 20.8% auto-HCT patients. The incidence of bacterial infections was higher in children (36.0% vs 27.6%; p 21 days were risk factors for death from infection. In conclusion, pediatric patients have 2.9-fold higher incidence and 2.5-fold better outcome of infections than adults after HCT
