  • 16 α-Hydroxyestrone induced adduct generate high affinity
           autoantibodies in SLE
    • Abstract: Publication date: March 2019Source: Advances in Medical Sciences, Volume 64, Issue 1Author(s): Wahid Ali Khan PurposeIncreased 16 α-hydroxyestrone (16 α-OHE1) and autoantibodies against histone H1 (H1) have been well described in systemic lupus erythematosus (SLE), but the combination effects of 16 α-OHE1 and H1 remains unclear. Here, we tried to assess the affinity and binding specificity of SLE autoantibodies against the 16 α-OHE1-H1 adduct. IgG was induced against this adduct and was also used as immunochemical probe for the estimation of 16 α-OHE1 in the serum of SLE patients.Materials and methodsThe affinity and binding specificities of SLE autoantibodies against 16 α-OHE1-H1 were determined by direct binding and inhibition ELISA as well as quantitative precipitation titration in 60 patients and 30 control subjects.ResultsPurified SLE autoantibodies showed greater recognition to 16 α-OHE1-H1 over H1 (p 
  • Beneficial effect of ovocystatin on the cognitive decline in APP/PS1
           transgenic mice
    • Abstract: Publication date: March 2019Source: Advances in Medical Sciences, Volume 64, Issue 1Author(s): Bartłomiej Stańczykiewicz, Marta Jakubik-Witkowska, Maria Rutkowska, Antoni Polanowski, Jakub Gburek, Krzysztof Gołąb, Katarzyna Juszczyńska, Tadeusz Trziszka, Joanna Rymaszewska PurposeCystatin C plays an important role in the course of neurodegenerative diseases and has a beneficial effect through inhibiting cysteine proteases and amyloid-β aggregation. It also induces proliferation and autophagy. Cystatin isolated from chicken egg white, called ovocystatin, has been widely used in the medical and pharmaceutical research due to its structural and biological similarities to human cystatin C. The aim of this study was to assess the effect of administering ovocystatin on the development of dementia-specific cognitive deficits in APP/PS1 transgenic mice.Materials/methodsThe study was conducted on transgenic B6C3-Tg(APPswe,PSEN1dE9)85Dbo/Mmjax mice. Ovocystatin was administered to four-month-old transgenic (AD) and wild type (NCAR) mice in drinking water for 24 weeks (at a dose of 40 and 4 μg/ mouse). The locomotor activity and cognitive functions were determined using an actimeter and the Morris water maze test, respectively.ResultsThe results of the study indicate that ovocystatin has a beneficial effect on the cognitive functions in APP/PS1 transgenic mice. The strongest effects of ovocystatin were found in the group of AD mice, where ovocystatin was administered in drinking water at a dose of 40 μg/mouse (p 
  • Epilepsy identification based on EEG signal using RQA method
    • Abstract: Publication date: March 2019Source: Advances in Medical Sciences, Volume 64, Issue 1Author(s): Iwona Gruszczyńska, Romuald Mosdorf, Piotr Sobaniec, Milena Żochowska-Sobaniec, Marta Borowska PurposeEpilepsy is one of the most common neurological diseases and its cause is not unequivocal. Thus, additional methods and searches that may help to diagnose the disease are used in the clinical practice. In this study, we tested the possibility of using the Recurrence Quantification Analysis (RQA) method to identify epilepsy and present the analysis of EEG signals of healthy patients and epileptic patients by the RQA method.Materials/methodsThe recordings of signals belong to 13 patients, which were divided into 2 groups: Group A (5 epileptic patients) and Group B (8 healthy patients). In this study Fp1, Fp2, T3 and T4 electrodes were considered in the analysis using the RQA method.ResultsIt is difficult to explore the dynamics of signals by linear methods. In this study, another way of analyzing the dynamics of signals by the RQA method is presented. The RQA method revealed differences in the dynamics between the epileptic and normal signals, which seemed important in an organoleptic way. It was found that the dynamics of epileptic signals is more periodic than normal signals. To confirm the correctness of the statements issued for the RQA data the Principal Component Analysis mapping was applied. This method showed more clearly the differences in the dynamics of both signals.ConclusionsThe RQA method can be used to identify nonlinear biomedical signals such as EEG signals.
  • Effect of Lactobacillus acidophilus and Porphyromonas gingivalis on
           proliferation and apoptosis of gingival epithelial cells
    • Abstract: Publication date: March 2019Source: Advances in Medical Sciences, Volume 64, Issue 1Author(s): Jun-jun Zhao, Long Jiang, Ya-qin Zhu, Xi-ping Feng PurposeThis study aimed to evaluate the possible antagonistic effects of Lactobacillus acidophilus on Porphyromonas gingivalis, and detect inhibition of Lactobacillus acidophilus on Porphyromonas gingivalis when they are co-cultured with human gingival epithelial cells.Materials and methodsHuman gingival epithelial cells were co-cultured with Lactobacillus acidophilus and Porphyromonas gingivalis alone or together. The amount of Porphyromonas gingivalis adhering to or invading the epithelial cells were determined by bacterial counts. The cellular proliferation was assayed by the MTT method. Apoptosis was detected by flow cytometry with apoptosis detection kit.ResultsOn one hand, Lactobacillus acidophilus reduced the inhibitory effect of Porphyromonas gingivalis on the human gingival epithelial cells proliferation in a dose dependent manner. On the other hand, Porphyromonas gingivalis induced significant apoptosis on human gingival epithelial cells, and Lactobacillus acidophilus inhibited this apoptosis-inducing effect of Porphyromonas gingivalis in a dose dependent manner.ConclusionsPorphyromonas gingivalis inhibits the proliferation and induces the apoptosis of human gingival epithelial cells. Lactobacillus acidophilus could attenuate this effect in a dose-dependent manner, and it thus reduces the destruction from pathogens. Lactobacillus acidophilus could be an effective candidate for probiotic therapy in periodontal diseases.
  • Association between gastric myoelectric activity disturbances and
           dyspeptic symptoms in gastrointestinal cancer patients
    • Abstract: Publication date: March 2019Source: Advances in Medical Sciences, Volume 64, Issue 1Author(s): Aneta L. Zygulska, Agata Furgala, Krzysztof Krzemieniecki, Beata Wlodarczyk, Piotr Thor PurposeDyspeptic symptoms present a severe problem in gastrointestinal (GI) cancer patients. The aim of the study was to analyze an association between gastric myoelectric activity changes and dyspeptic symptoms in gastrointestinal cancer patients.Material and MethodsThe study included 80 patients (37 men and 43 women, mean age 61.2 ± 7.8 years) diagnosed with GI tract malignancies: colon (group A), rectal (group B) and gastric cancers (group C). Gastric myoelectric activity in a preprandial and postprandial state was determined by means of a 4-channel electrogastrography. Autonomic nervous system was studied based on heart rate variability analysis. The results were compared with the data from healthy asymptomatic controls.ResultsIn a fasted state, GI cancer patients presented with lesser percentages of normogastria time (A:44.23 vs. B:46.5 vs. C:47.10 vs. Control:78.2%) and average percentage slow wave coupling (ACSWC) (A:47.1 vs. B:50.8 vs. C:47.2 vs. Control:74.9%), and with higher values of dominant power (A:12.8 vs. B:11.7 vs. C:12.3 vs. Control:10.9) than the controls. Patients did not show an improvement in the percentage of normogastria time, dominant power, dominant frequency and ACSWC in response to food. The severity of dyspeptic symptoms correlated with the values of electrogastrography parameters. Patients showed lower values of heart rate variability parameters than the healthy controls, that indicate abnormal autonomic nervous system activity.ConclusionGI cancers affect the gastric myoelectric activity, decreasing normogastria and slow wave coupling. These patients do not show adequate gastric motility response to food. Impaired gastric electric motility may result from cancer-induced autonomic disturbances.
  • Fluid therapy in non-septic, refractory acute decompensated heart failure
           patients – The cautious role of central venous pressure
    • Abstract: Publication date: March 2019Source: Advances in Medical Sciences, Volume 64, Issue 1Author(s): Malgorzata Chlabicz, Remigiusz Kazimierczyk, Paulina Lopatowska, Monika Gil-Klimek, Bartosz Kudlinski, Marcin Ligowski, Bozena Sobkowicz, Marek Gierlotka, Karol Kaminski, Agnieszka Tycinska PurposeFluid therapy in congestive acute decompensated heart failure (ADHF) patients might be inappropriate and worsening the prognosis. The aim of our study was to analyze the effect of fluid administration on mortality in non-septic, ADHF patients with reduced ejection fraction.Material and methodsWe analyzed 41 ADHF consecutive ‘cold-wet’ patients (mean age 69.3 ± 14.9 years, 27 men, LVEF 22.8 ± 11.1%, lactates 2.2 ± 1.6 mmol/L) without sepsis. At admission central venous pressure (CVP) was measured (17.6 ± 7.2 cm H2O), and ultrasound examination of inferior vena cava (IVC) was performed (IVC min. 18.6 ± 7.3 mm and IVC max. 24.6 ± 4.3 mm). Moreover, the groups were compared (survivors vs. non-survivors as well as 1st and 4th quartile of CVP).ResultsAltogether 17 (41%) patients died: 16 (39%) during a mean of 11.2 ± 7.8 days of hospitalization and 1 during a 30-day follow up. Patients in the lowest CVP quartile (24 cm H2O), P = 0.012. Higher intravenous fluid volumes within the first 24 h were infused in patients in the lowest CVP quartile as compared to the highest CVP quartile (1791.7 ± 1357.8 mL vs. 754.5 ± 631.4 mL, P = 0.046). Moreover, more fluids were infused in a group of patients who died during a hospital stay and at 30-day follow up (1362.8 ± 752.7 mL vs. 722.7 ± 1046.5 mL, P = 0.004; 1348.8 ± 731.0 mL vs. 703.6 ± 1068.4 mL, P = 0.002, respectively).ConclusionsCVP-guided intravenous fluid therapy is a common practice which in high risk ADHF ‘cold-wet’ patients might be harmful and should rather be avoided. Lower CVP seems to be related with worse prognosis.
  • Hypertension prevalence in early breast cancer patients undergoing primary
    • Abstract: Publication date: March 2019Source: Advances in Medical Sciences, Volume 64, Issue 1Author(s): Klaudia Kozłowska, Leszek Kozłowski, Jolanta Małyszko PurposeTreatment with chemotherapy and targeted drugs may results in elevated risk of cardiac and renal toxicity as well as hypertension. However, data on prevalence of chronic kidney disease and hypertension in subjects with early breast cancer undergoing primary surgery are very limited.Patients and methodsThe study aimed to assess the prevalence of chronic kidney disease and hypertension (evaluated as a preoperative assessment and defined according to ESC/ESH guidelines) in a cohort of 100 consecutive female patients with early breast cancer treated with primary surgery with curative intent.ResultsPatients with breast cancer were 53 ± 14 years of age, with serum creatinine of 0.68 ± 0.14 mg/dl and estimated glomerular filtration rate by chronic kidney disease-epidemiological collaboration formula of 99 ± 18 mL/min/1.72 m2. Hypertension was present in 37%, but in the elderly patients (over 65 years) the prevalence was 74%. Hypertensive females had worse kidney function as reflected by higher serum creatinine and lower estimated glomerular filtration rate, higher body mass index and fibrinogen, which reflects general inflammatory state. When we divided the patients according to age (≤ vs>65 years) and the presence of hypertension, the elderly hypertensive females had significantly worse kidney function, higher fibrinogen and fasting glucose.ConclusionsThe prevalence of hypertension in patients with breast cancer raises with age, and presence of comorbidities, including chronic kidney disease. Hypertension should be treated promptly to prevent cardiovascular complications during oncological therapy.
  • Activity of lysosomal exoglycosidases in the urine of healthy normotensive
           and pre-hypertensive children
    • Abstract: Publication date: March 2019Source: Advances in Medical Sciences, Volume 64, Issue 1Author(s): Beata Zalewska-Szajda, Katarzyna Taranta-Janusz, Sylwia Chojnowska, Napoleon Waszkiewicz, Krzysztof Zwierz, Anna Wasilewska PurposeWe investigated the relationship between blood pressure (BP) and the activity of lysosomal exoglycosidases: N-acetyl-β-hexosaminidase (HEX), its isoenzymes A (HEX A) and B (HEX B), α-fucosidase (FUC), β-galactosidase (GAL), β-glucuronidase (GLU) and α-mannosidase (MAN) in pre-hypertensive (high normal blood pressure - HNBP) and normal blood pressure (NBP) children.Material and methodsThe study was carried out with urine samples collected from 176 children, aged 6–17.9 years, divided into 2 groups: 42 HNBP and 134 NBP subjects. The children were stratified depending on systolic and diastolic BP (SBP; DBP): HNBP (SBP and/or DBP greater than or equal to the 90th percentile, but less than the 95th percentile) for sex, age, and height; and NBP (SBP and DBP less than the 90th centile). The activities of lysosomal exoglycosidases were determined by the colorimetric method, and expressed in pKat/mL and pKat/μgCr.ResultsThe activity of urinary HEX A in HNBP group was significantly higher than in NBP (p 
  • Long-term administration of fatty acid amide hydrolase inhibitor (URB597)
           to rats with spontaneous hypertension disturbs liver redox balance and
           phospholipid metabolism
    • Abstract: Publication date: March 2019Source: Advances in Medical Sciences, Volume 64, Issue 1Author(s): Michał Biernacki, Ewa Ambrożewicz, Agnieszka Gęgotek, Marek Toczek, Elżbieta Skrzydlewska PurposeThe effect of chronic administration of [3-(3-carbamoylphenyl)phenyl] N-cyclohexylcarbamate (URB597), inhibitor of fatty acid amide hydrolase (FAAH) that hydrolyzes anandamide, on cross-talk between endocannabinoid system, oxidative status and pro-inflammatory factors in the liver of spontaneously hypertensive rats (SHRs) was investigated.Materials/methodsExperiments were conducted using SHRs and normotensive control Wistar-Kyoto rats treated by intraperitoneal injection with URB597 for 14 days. The biochemical parameters were assayed in the rat’s livers.ResultsIn the liver of SHRs an increase in endocannabinoids level, the activity of enzymes degrading them and expression of the cannabinoid receptor type 2 (CB2) receptor as well as a decrease in the expression of the CB1 and vanilloid 1 receptor (TRPV1) were shown. These changes were related to inflammatory conditions as well as oxidative stress resulting from increased reactive oxygen species (ROS) generation due to enhanced activity of enzymes generating ROS accompanied by decrease in the effectiveness of transcription activity of nuclear factor erythroid 2 and the activity of antioxidant enzymes, as well as level of glutathione and vitamins. Chronic administration of URB597 to SHRs caused a decrease in FAAH activity and an increase in anandamide and N-arachidonoyl-dopamine level as well as a decrease in CB2 and an increase in TRPV1 receptor expression. The levels/activities of pro- and antioxidant and inflammatory factors tended to normalize, but phospholipid peroxidation and DNA modifications were increased.ConclusionIn conclusion, long-term chronic administration of URB597 to SHRs by altering interactions between endocannabinoid and redox systems enhances some liver metabolic disturbances observed in hypertension.
  • Diagnostic power of VEGF, MMP-9 and TIMP-1 in patients with breast cancer.
           A multivariate statistical analysis with ROC curve
    • Abstract: Publication date: March 2019Source: Advances in Medical Sciences, Volume 64, Issue 1Author(s): Monika Zajkowska, Ewa Gacuta, Sylwia Kozłowska, Emilia Lubowicka, Edyta K. Głażewska, Lech Chrostek, Maciej Szmitkowski, Przemysław Pawłowski, Monika Zbucka-Krętowska, Sławomir Ławicki PurposeVascular endothelial growth factor is an important factor in promoting angiogenesis in malignant processes, matrix metalloproteinase-9 in the degradation of extracellular matrix, which enhances metastasis, and tissue inhibitor of metalloproteinase-1 is its inhibitor. The aim of this study was to investigate the diagnostic power of these parameters in comparison to CA15-3 in breast cancer patients and in relation to the control group.Materials/methodsThe study included 120 breast cancer patients, 60 patients with benign breast tumors and 60 healthy women. Plasma levels of tested parameters were determined by enzyme-linked immunosorbent assay, CA15-3 by chemiluminescent microparticle immuno assay.ResultsTissue inhibitor of metalloproteinase-1 showed the highest value of sensitivity in breast cancer group (86.25%) and, more importantly, highest value in breast cancer stage I (85%). Vascular endothelial growth factor also showed high sensitivity (stage I and II–75%, III–85%, IV–70% and 76.25% in total breast cancer group) and the highest specificity (85%) from all tested parameters. It was also the only parameter which had statistically significant area under curve in all stages. In the total breast cancer group all tested parameters showed statistically significant area under curve, but the maximum range was obtained for combination: ‘vascular endothelial growth factor + CA15-3′. Vascular endothelial growth factor seems to be the best candidate for diagnosing breast cancer stage I and for differentiating between breast cancer and non-carcinoma cases.ConclusionsThe combined analysis of tested parameters and CA15-3 resulted in an increase in sensitivity and area under curve values, which provides hope for developing new panel of biomarkers that may be used in diagnosing breast cancer in the future.
  • TiC-composite materials in applications for kinematic denture connections
    • Abstract: Publication date: September 2018Source: Advances in Medical Sciences, Volume 63, Issue 2Author(s): Marek Jałbrzykowski, Jan R. Dąbrowski, Łukasz Minarowski PurposeThis paper presents an own proposal for the construction of a ball latch intended for use in prosthetic dentistry. Attention was paid to the existing commercial constructions of elements of the same type, indicating their advantages and disadvantages. Based on the analysis of the present solutions, own ones were proposed.Materials and methodsThe following materials were chosen for the tests: pure titanium, 316 L V steel, Ti15Mo2.8Nb obtained using powder metallurgy and through mechanical alloying, 10 and 20% of titanium carbide – obtained using powder metallurgy, as well as 10 and 20% of graphite – obtained using powder metallurgy. For the prepared materials, tribological tests were performed using a friction simulator in a ring/shield system.ResultsFairly extensive tests were performed to verify the suitability of the selected material for use in the specific conditions of the oral cavity. The performed tests showed that the proposed material is not only beneficial in relation to the existing commercial dental alloys but also meets the general criteria set for this type of elements.ConclusionsA more beneficial use of two–part ball latches (two key parts – patrix, matrix) was noticed in comparison to latches consisting of three parts (patrix, insert, matrix). On the basis of the obtained test results, it can be concluded that the proposed own design of a ball latch is a good alternative for traditional constructional and material solutions of commercial ball latches.
  • Fatty acids profile in patients after heart or renal transplantation who
           developed metabolic complications
    • Abstract: Publication date: September 2018Source: Advances in Medical Sciences, Volume 63, Issue 2Author(s): Małgorzata Wilusz, Dominik Cieniawski, Grzegorz Wasilewski, Marek Kuźniewski, Władysław Sułowicz, Krystyna Sztefko PurposeDiabetes mellitus and hyperlipidemia are frequently observed after organ transplantation. It is known that in these disorders the fatty acid metabolism is impaired. The aim of this study was to compare the fatty acid profile in the heart and renal transplant recipients who developed metabolic disorders since there is no such research available.Materials and methodsThe study included 55 patients treated with tacrolimus (Tac) after heart (n = 14; mean age: 60.4 ± 9.1) or renal (n = 41; mean age: 51 ± 13) transplantation. Diabetes and hyperlipidemia was present in 35.7% and 28.5% of heart transplant recipients, and 19.5% and 41% of renal transplant recipients. Concentrations of fatty acid in phospholipids fraction in serum were measured by gas chromatography.ResultsThe concentration of C20:5 fatty acid was lower in heart transplant recipients, as compared to renal transplant recipients (p = 0.001), whereas the level of C20+C18:3 fatty acid and the ratio of n-6/n-3 was higher (p = 0.01; p = 0.03, respectively). The observed differences were not related to metabolic disorders. Negative correlation between C16:1 and eGFR was seen in heart transplant recipients (p = 001). In renal transplant recipients with metabolic disorders, the concentration of C20:5 was correlated positively whereas the n-6/n-3 ratio was correlated negatively with eGFR (p 
  • The added value of magnifying endoscopy in diagnosing patients with
           certain gastroesophageal reflux disease
    • Abstract: Publication date: September 2018Source: Advances in Medical Sciences, Volume 63, Issue 2Author(s): Justyna Wasielica-Berger, Andrzej Kemona, Joanna Kiśluk, Agnieszka Świdnicka-Siergiejko, Paweł Rogalski, Adam Chwieśko, Maja Kostrzewska, Andrzej Dąbrowski PurposeIn most cases gastroesophageal reflux disease proceeds without macroscopic erosions in the esophagus. We aimed to clarify if abnormalities detectable in magnifying endoscopy may offer additional diagnostic criteria for gastroesophageal reflux disease and to what histopathologic structures do they correspond.Patients/methodsEsophageal mucosa above and below Z-line was evaluated under x115 magnification in 67 gastroesophageal reflux disease patients (11 with erosive reflux disease, 28 with Barrett’s esophagus, 28 with nonerosive reflux disease) and in 12 patients without gastroesophageal reflux disease (negative control group). Features characteristic of gastroesophageal reflux disease were specified by comparing erosive reflux disease and Barrett’s esophagus patients with negative control group. Afterwards the presence of identified features were evaluated in nonerosive reflux disease group. Interobserver agreement in the recognition of the proposed criteria was rated. Biopsies collected from the mucosa above Z-line were evaluated histologically after hematoxylin and eosin staining.ResultsEndoscopic lesions characteristic of gastroesophageal reflux disease were: microerosions, abnormal intrapapillary capillary loops, obscured palisade vessels, white points, big triangular indentations of Z-line and villous mucosa below Z-line. The presence of two or more of the above features indicated gastroesophageal reflux disease with 97% sensitivity and 75% specificity. Substantial interobserver agreement was achieved in evaluation of obscured palisade vessels, abnormal intrapapillary capillary loops and white points. Endoscopic lesions were correlated to histology. Lesions identified with magnifying endoscopy were helpful in discerning between negative control group and nonerosive reflux disease patients.ConclusionsMagnifying endoscopy reveals abnormalities that can be used as additional endoscopic diagnostic criteria of gastroesophageal reflux disease.
  • Effect of maternal weight during pregnancy on offspring muscle strength
           response to resistance training in late adulthood

Salonen, Samuel Sandboge, Johan G. Eriksson PurposeMaternal obesity can unfavorably influence offspring body composition, muscle strength, and possibly muscle’s adaptability to training, but the human studies are scarce. Therefore, we aimed to investigate the effect of maternal obesity on offspring muscle strength responses to resistance training intervention in elderly frail women.Materials/methodsRecruited participants were elderly frail women offspring of lean/normal weight mothers (n = 19, mean body mass index (BMI): 22.8 kg/m2, range: 19.9–24.5) or overweight/obese mothers (n = 16, mean BMI: 29.7 kg/m2, range: 28.2–34.2). Information on maternal BMI immediately prior to delivery was collected from the birth registers. All women participated in a 4-month supervised progressive resistance training intervention three times a week for 60 min. Predicted 1-RM of abdominal crunch, hip abduction, leg curl, leg press, seated row, and total strength were measured at baseline and after each month of training.ResultsAccording to rANOVA, strength increased significantly in both groups (p for time 0.072). On average, muscle strength of the women offspring of overweight/obese mothers tended to be lower than in women offspring of lean/normal weight mothers, but the only significant difference was found in leg curl (p = 0.006). No significant differences between the groups were found in relative strength changes from baseline to 4-months.ConclusionsMuscle strength response to supervised resistance training is not modulated by maternal adiposity in late pregnancy in elderly frail female offspring.
  • Topical folinic acid enhances wound healing in rat model
    • Abstract: Publication date: September 2018Source: Advances in Medical Sciences, Volume 63, Issue 2Author(s): Nilay Duman, Reşat Duman, Murat Tosun, Murat Akıcı, Engin Göksel, Barış Gökçe, Oğuzhan Alagöz PurposeFolic acid is an essential vitamin participating in DNA synthesis and repair. Recently folic acid has been shown to stimulate DNA-repair capacity in dermal fibroblasts in response to injury. Thus, the present study aimed to investigate the effects of topical folinic acid, a 5-formyl derivative of tetrahydrofolic acid, on wound healing using rat wound model.Materials and methodsA rat wound model was established, and the wound healing was evaluated by macroscopic and histological analyses among vehicle control, 2.5% folinic acid, 1% folinic acid, and dexpanthenol treatment groups. While an image-analysis program was used to evaluate macroscopic wound closure, connective tissue properties, mast cell numbers, and the expressions of matrix metalloproteinase 1 (MMP-1) and 9 (MMP-9) were evaluated by microscopy.ResultsThe 2.5% folinic acid-treated group exhibited enhanced wound healing by increased reepithelialization, neo-vessel formation, inflammatory cell migration, collagen deposition and progressive mast cell increase. Furthermore, 2.5% folinic acid induced higher expressions of MMP-1 and MMP-9.ConclusionsFolinic acid enhances both macroscopic and microscopic wound healing in rat wound model.
  • Vitamin E status and its determinants in patients with cystic fibrosis
    • Abstract: Publication date: September 2018Source: Advances in Medical Sciences, Volume 63, Issue 2Author(s): Ewa Sapiejka, Patrycja Krzyżanowska-Jankowska, Ewa Wenska-Chyży, Mariusz Szczepanik, Dariusz Walkowiak, Szczepan Cofta, Andrzej Pogorzelski, Wojciech Skorupa, Jarosław Walkowiak PurposeThe risk of vitamin E deficiency is of primary concern in cystic fibrosis patients. However, early diagnosis and routine vitamin E supplementation can lead to its normal or even high levels. In the present study, we assessed vitamin E status in a large group of cystic fibrosis patients. Moreover, we also aimed to establish determinants of its body resources in cystic fibrosis patients.Material and methodsThe study group comprised 211 cystic fibrosis patients aged from 1 month to 48 years. In all of them serum α-tocopherol concentration was analyzed using high-performance liquid chromatography.ResultsMedian vitamin E concentration was 9.9 μg/ml (1st–3rd quartile: 7.5–13.5). Vitamin E deficiency was found in 17 (8.0%) and high levels were documented in 24 (11.4%) participants. Patients with and without vitamin E deficiency did not differ significantly with respect to age, standardized body weight and height, FEV1, albumin concentration and vitamin E supplementation dose. However, vitamin E deficiency appeared more frequently in participants without vitamin E supplementation. Moreover, in multiple linear regression analysis pancreatic insufficiency, severe CFTR gene mutation and vitamin E dose, were potentially defined as determinants of vitamin E concentration.ConclusionsVitamin E deficiency in cystic fibrosis patients is rather rare nowadays. Excessive vitamin E levels seem to be more frequent. Vitamin E status wasn’t documented to be strictly related to clinical determinants. Beyond vitamin E supplementation, exocrine pancreatic function and CFTR gene mutations may have had an impact on the vitamin E body resources in cystic fibrosis patients.
  • Cardiac and autonomic function in patients with Crohn’s disease

Klawe, Julia L. Newton, Paweł Zalewski PurposeThe aim of the study was to assess cardiac and autonomic function in patients with Crohn’s disease and explore their relation to disease duration using cardiovascular reflex tests.Materials and methodsCardiovascular parameters, baroreflex sensitivity, spectral-indices of short-term heart rate variability and blood pressure variability were compared between patients with Crohn’s disease in remission (n = 30) and a control group (n = 29). Cardiac autonomic function was assessed during response to standing (tilt) and deep breathing test (expiration/inspiration ratio-E/I). Aortic pulse wave velocity, aortic augmentation index and central systolic blood pressure were measured oscillometrically.ResultsAt rest, Crohn’s disease patients had significantly higher systolic (p = 0.03) and diastolic (p = 0.03) blood pressure, total peripheral resistance index (p = 0.003), sympathetic-parasympathetic ratio (p = 0.033) and lower baroreceptor effectiveness (p = 0.047), myocardial variables (stroke index; p = 0.03, cardiac index; p = 0.025, Heather index; p = 0.039, left ventricular ejection time; p = 0.038), as compared to controls. Orthostatic response to the tilt test in the Crohn’s disease group and the control group was similar, no intergroup differences were observed for E/I ratio and autonomic parameters. In Crohn’s disease patients, disease duration was negatively associated with baroreflex sensitivity and positively correlated with normalised high frequency heart rate variability, sympathetic-parasympathetic ratio at rest and post-tilt changes in Δsystolic blood pressure, p

The study group was divided based on BMI and HOMA-IR values, and the occurrence of diabetes.ResultsPlasma RBP4 concentration was similar in normal weight, overweight, and obese subgroups, both in women (40.4 vs 40.8 vs 41.8 ng/ml, respectively), and men (41.2 vs 40.3 vs 42.9 ng/ml, respectively). Similar values were found in subjects with HOMA-IR
  • HLA-G and anti-HCV in patients on the waiting list for kidney
    • Abstract: Publication date: September 2018Source: Advances in Medical Sciences, Volume 63, Issue 2Author(s): Linda Sommese, Rossella Paolillo, Francesco Cacciatore, Vincenzo Grimaldi, Chiara Sabia, Antonella Esposito, Antonio Sorriento, Carmela Iannone, Nicolò Rupealta, Gerardo Sarno, Michele Santangelo, Paride De Rosa, Gianfranco Nicoletti, Claudio Napoli PurposeHuman leukocyte antigen (HLA)-G is a non-classic major histocompatibility complex HLA class I molecule. HLA-G may have tolerogenic properties which are linked to epigenetic-sensitive pathways. There is a correlation of sHLA-G levels and graft acceptance in transplantation studies. There are previous data on correlation of sHLA-G with graft rejection as well as with viral infections such as hepatitis C virus (HCV) in kidney transplanted patients. Here, we report the sHLA-G expression in patients on the waiting list for kidney transplantation, with and without anti-HCV compared to a control group.MethodsSerum of 67 patients on the waiting list for kidney transplantation (n = 43 with anti-HCV and n = 24 without anti-HCV) was analyzed. Among these patients, n = 39 were on the waiting list for the first transplantation, while n = 28 were patients who returned in the list. The control group included n = 23 blood donors with anti-HCV (n = 13) and without anti-HCV (n = 10).ResultsThe expression of sHLA-G was significantly lower in the control group (39.6 ± 34.1 U/ml) compared to both - patients on the waiting list for the first transplantation (62.5 ± 42.4 U/ml, p=0.031) and patients who returned in the list (76.7 ± 53.9 U/ml, p=0.006). No significant differences were observed in all anti-HCV positive groups. A positive linear correlation between sHLA-G and TNF-α, and patient age was observed.ConclusionsSerum sHLA-G values were significantly increased in both - patients on the waiting list for the first transplantation and patients who returned in the list, as compared to control group. Our findings confirm the key tolerogenic role of sHLA-G levels as epigenetic-related marker for measuring the state of kidney allograft acceptance.

  • Expression profile and cellular localizations of mucin proteins, CK7, and
           cytoplasmic p27 in Barrett’s esophagus and esophageal adenocarcinoma
    • Abstract: Publication date: September 2018Source: Advances in Medical Sciences, Volume 63, Issue 2Author(s): H. Ece Arslan Ozcan, Turgut Anuk, Ozkan Ozden PurposeBarrett's esophagus is one of the main risk factors for increased incidence of esophageal adenocarcinoma. In this study, we studied protein expression levels and cellular localizations of MUC-1, MUC-2, MUC-5AC, CK7, and cytoplasmic p27 to assess the relationship between the expression of each of these proteins and the disease progression on endoscopic biopsies.Materials and methodsImmunohistochemical analyses were performed using antibodies produced against MUC-1, MUC-2, MUC-5AC, CK7, and p27. Endoscopic specimens of esophageal mucosa were obtained from 72 patients who underwent esophagectomy for Barrett’s esophagus, metaplasia, dysplasia, or esophageal adenocarcinoma developed from Barrett’s esophagus.ResultsMultilayer squamous epithelium showed only MUC-1 positivity in the EAC group while MUC-2 and MUC-5AC staining could not be detected in this group. Strong and diffused membranous or cytoplasmic staining of CK7 was observed at squamous, ductal, surface columnar and/or glandular epithelium. c-p27 staining was diffused and moderate in the cellular membranes observed in all groups except for esophageal epithelial metaplasia without intestinal metaplasia. Additionally, weakly focal cytoplasmic staining in squamous epithelium of p27 in EAC was detected.ConclusionsBarrett's esophagus, which has a heterogeneous epithelium, might yield different diagnosis based on endoscopic evaluation and immunohistological investigation. Thus, the use of MUC1, p27, and CK7 might strengthen the truthful diagnosis. MUC-1, CK7, and c-p27 immunostaining can be used as the predictive markers for esophageal cancer progression from Barrett’s esophagus.

    • Abstract: Publication date: September 2018Source: Advances in Medical Sciences, Volume 63, Issue 2Author(s): Hanna Pituch, Piotr Obuch-Woszczatyński, Dominika Lachowicz, Robert Kuthan, Katarzyna Dzierżanowska-Fangrat, Agnieszka Mikucka, Katarzyna Jermakow, Aleksandra Pituch-Zdanowska, Kerrie Davies, Polish EUCLID C. difficile Study Group PurposeWe aimed to measure the underdiagnosis of Clostridium difficile infection across Poland and the distribution of PCR-ribotypes of C. difficile.Material and methodsTwenty seven Polish healthcare facilities (HCFs) participated in this prospective study. Each HCF systematically sent all diarrhoeal stools received from inpatients at their laboratories on two days (one in January 2013 and one in July 2013), independently of CDI test request, to the National Coordinating Laboratory (NCL) for standardized testing of CDI. Positive samples (using two-stage algorithm), had CDI, confirmed by qPCR and toxigenic culture. C. difficile isolates were characterized by PCR-ribotyping. Hospitals were questioned about their methods and testing policy for CDI during the study period: September 2011 to August 2013.ResultsDuring the study period, participating hospitals reported a mean of 33.2 tests for CDI per 10 000 patient-days and a mean of 8.4 cases of CDI per 10 000 patient-days. The overall prevalence of positive CDI patients at NCL was 16.5%. Due to absence of clinical suspicion, 19.1% of these patients were not diagnosed by the local diagnostic laboratory. We identified 23 different PCR-ribotypes among 87C. difficile strains isolated from patients. PCR-ribotype 027 (48%) was the most prevalent.ConclusionsThe incidence of CDI in Poland in study period was very high. It should be noted however, that there is a lack of clinical suspicion and underestimation of the need to perform diagnostic tests for CDI in hospitalized patients. This will have an impact on the reported epidemiological status of CDI in Poland.

However, the PR/RR ratio has never been evaluated in a large group of patients with pacing from the proximal coronary sinus and after isoproterenol challenge. Our study validates new site of pacing and easier method of identification of PR > RR.Material and methodsA prospective protocol of incremental atrial pacing from the proximal coronary sinus was carried out in 398 patients (AVNRT-228 and control-170). The maximum stimulus to the Q wave interval (S-Q = PR), SS interval (S-S), and Q-Q (RR) interval were measured at baseline and 10 min after successful slow pathway ablation and after isoproterenol challenge (obligatory).ResultsThe mean maximum PR/RR ratios at baseline were 1.17 ± 0.24 and 0.82 ± 0.13 (p

    • Abstract: Publication date: September 2018Source: Advances in Medical Sciences, Volume 63, Issue 2Author(s): Ewa Czeczuga-Semeniuk, Marzenna Galar, Katarzyna Jarząbek, Piotr Kozłowski, Nela A. Sarosiek, Sławomir Wołczyński PurposeWe aimed to elucidate the frequency of the SNPs in the ADIPOQ, RBP4 and BCMO1genes in a population of Caucasian Polish women with polycystic ovary syndrome (PCOS), and to evaluate the possible associations between these variants and the susceptibility to PCOS. Additionally, the relationship of these polymorphisms to a clinical phenotype of this syndrome, and the concentrations of adipokines, were determined.Materials/methodsClinical and biochemical profiles, DNA isolation and genotyping, and adipokine assays were performed in 294 PCOS women and 78 controls.ResultsIn a cohort of Polish women, for the genotype distribution and allele frequencies (minor allele frequency − MAF) proved that only the SNP rs1501299 in the gene ADIPOQ (P = 0.0010, OR = 0.41, 95% C.I.:0.24-0.70) and rs7501331 in the gene BCMO1 (P = 0.0106, OR = 0.24, 95% C.I.:0.21-0.71), are significantly associated (the latter marginally significant) with the decrease of the risk of the disease. Also for this SNPs there were significant differences in the genotypic frequencies in the study population.There was a link between rs12934922 of BCMO1 gen and serum concentration of RBP4 (P = 0.034) and adiponectin (P = 0.038) in the study group but not in the control group. The elevated mean serum concentration of cholesterol (P = 0.020) and LDL cholesterol (P = 0.005) was observed for GG rs1501299 genotype and triglycerides (P = 0.028) for TT rs2241766 genotype.ConclusionsThe results of the present study revealed that the genes variants RBP4 is not associated with PCO. It seems that rs1501299 of ADIPOQ gene influences the occurrence of PCO and lipids profile in those patients.

IA might be formed after all types of surgical interventions regardless the surgical approach with a higher incidence in obese individuals. Here we determine the diagnostic power of TGF-β and blood inflammatory parameters in the prediction of IA in obese patients undergoing second surgical intervention.Materials and methodsEighty patients were divided into groups according to body mass index (BMI) values and presence of intraperitoneal adhesions (IA). Evaluation of peritoneal adhesion index (PAI), serum TGF-β and blood inflammatory parameters was performed.ResultsLevel of TGF-β, C-reactive protein (CRP), leukocytes, neutrophil to lymphocyte ratio and platelet to lymphocyte ratio were significantly higher in obese patients while TGF-β, CRP, and leukocytes were higher in patients with IA. There was a significant correlation between PAI values and TGF-β concentration (p 
  • Activation of mitochondrial KATP channels mediates neuroprotection induced
           by chronic morphine preconditioning in hippocampal CA-1 neurons following
           cerebral ischemia
    • Abstract: Publication date: September 2018Source: Advances in Medical Sciences, Volume 63, Issue 2Author(s): Maedeh Arabian, Nahid Aboutaleb, Mansoureh Soleimani, Marjan Ajami, Rouhollah Habibey, Hamidreza Pazoki-Toroudi PurposePharmacologic preconditioning, through activating several mechanisms and mediators, can increase the tolerance of different tissues against ischemia/reperfusion (I/R) injury. Recent studies have shown that morphine preconditioning has protective effects in different organs, especially in the heart. Nevertheless, its mechanisms are not well elucidated in the brain. The present study aimed to clarify whether the activation of mitochondrial KATP (mKATP) channels in chronic morphine (CM) preconditioning could decrease hippocampus damage following I/R injury.Materials and methodsCM preconditioning was performed by the administration of additive doses of morphine for 5 days before I/R injury induction. I/R injury was induced by the occlusion of bilateral common carotid arteries. The possible role of mKATP channels was evaluated by the injection of 5-hydroxydecanoate (5-HD) before I/R injury. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) was performed to detect apoptosis in hippocampal neurons. The expressions of B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (BAX) and levels of malondialdehyde (MDA) and catalase (CAT) enzymes were assessed.ResultsCM attenuated apoptosis in the hippocampal CA1 neurons (P 
  • The role of platelets in the development and progression of pulmonary
           arterial hypertension
    • Abstract: Publication date: September 2018Source: Advances in Medical Sciences, Volume 63, Issue 2Author(s): Remigiusz Kazimierczyk, Karol Kamiński Pulmonary arterial hypertension is a multifactorial disease characterized by vasoconstriction, vascular remodeling, inflammation and thrombosis. Although an increasing number of research confirmed that pulmonary artery endothelial cells, pulmonary artery smooth muscle cells as well as platelets have a role in the pulmonary arterial hypertension pathogenesis, it is still unclear what integrates these factors. In this paper, we review the evidence that platelets through releasing a large variety of chemokines could actively impact the pulmonary arterial hypertension pathogenesis and development. A recent publication revealed that not only an excess of platelet derived cytokines, but also a deficiency may be associated with pulmonary arterial hypertension development and progression. Hence, a simple platelet blockade may not be a correct action to treat pulmonary arterial hypertension. Our review aims to analyse the interactions between the platelets and different types of cells involved in pulmonary arterial hypertension pathogenesis. This knowledge could help to find novel therapeutic options and improve prognosis in this devastating disease.
  • Interactions between the growth hormone and cytokines – A review
    • Abstract: Publication date: September 2018Source: Advances in Medical Sciences, Volume 63, Issue 2Author(s): Mieczysław Szalecki, Anna Malinowska, Monika Prokop-Piotrkowska, Roman Janas Numerous reports on the interactions between the immune and endocrine systems, especially growth hormone axis, can be found in the literature. Growth hormone acts mainly indirectly through insulin-like growth factor-1, which stimulates the growth and development processes, metabolism of lipids, proteins, and carbohydrates, and it also has a modulating effect on the cells of the immune system.Several studies have been conducted on the influence of growth hormone therapy on the immunological parameters in children and adults with and without growth hormone deficiency. However, there have been no definite results and some of them have been even contradictory. Some studies have suggested that administration of growth hormone increases the production of tumor necrosis factor and certain pro- and anti-inflammatory cytokines; whereas other studies have demonstrated the lack of correlation between growth hormone and interleukins.The aim of this paper was to evaluate the available literature on the interaction between growth hormone and TNF-α, pro-inflammatory (IL-1β, IL-2, IL-6) and anti-inflammatory (IL-4, IL-10) interleukins.
  • Th9 lymphocytes and functions of interleukin 9 with the focus on IBD
    • Abstract: Publication date: September 2018Source: Advances in Medical Sciences, Volume 63, Issue 2Author(s): Krzysztof Matusiewicz, Barbara Iwańczak, Małgorzata Matusiewicz The work presents the newest knowledge on a new phenotype of T helper lymphocytes (Th9) and on Interleukin 9 (IL-9). Processes leading to transformation of naïve T lymphocyte into Th9 lymphocytes are presented, including the role of IL-4 and TGFβ signaling. Involvement of transcription factor network in production of IL-9 is described. Other cells capable of expressing IL-9 and secreting IL-9 are portrayed. Diversity of IL-9 effects caused by activation of IL-9 receptors on various types of cells is presented. Principal effects of the activation of IL-9 receptor on T-cells seem to be antiapoptotic and stimulatory which leads to enhanced defense against parasitic infection and cancer development but, from the other side, it perpetuate chronic inflammation in autoimmune diseases and allergic processes. In the last years the role of IL-9 in autoimmune diseases such as rheumatic diseases and inflammatory bowel disease gained importance since the increased expression of this cytokine has been observed in animal models of intestinal inflammation and in groups of patients with ulcerative colitis. It was also noted that neutralization of IL-9 in animal models of ulcerative colitis leads to amelioration of inflammatory process, what could have significance in the treatment of this disease in humans in the future.
  • Markers of anaphylaxis – a systematic review
    • Abstract: Publication date: September 2018Source: Advances in Medical Sciences, Volume 63, Issue 2Author(s): Maria Magdalena Tomasiak-Łozowska, Maciej Klimek, Agnieszka Lis, Marcin Moniuszko, Anna Bodzenta-Łukaszyk Anaphylaxis is defined as severe, life-threatening, systemic or general, immediate reaction of hypersensitivity, with repeatable symptoms caused by the dose of stimulus which is well tolerated by healthy persons. The proper diagnosis, immediate treatment and differential diagnosis are crucial for saving patient's life. However, anaphylaxis is relatively frequently misdiagnosed or confused with other clinical entities. Thus, there is a continuous need for identifying detectable markers improving the proper diagnosis of anaphylaxis. Here we presented currently known markers of anaphylaxis and discussed in more detail the most clinically valuable ones: tryptase, platelet activacting factor (PAF), PAF-acethylhydrolase, histamine and its metabolites.
