Pioneering Metabolomic Studies on Diaporthe eres Species Complex from Fruit Trees in the South-Eastern Poland.

Fungi from the genus Diaporthe have been reported as plant pathogens, endophytes, and saprophytes on a wide range of host plants worldwide. Their precise identification is problematic since many Diaporthe species can colonize a single host plant, whereas the same Diaporthe species can inhabit many hosts. Recently, Diaporthe has been proven to be a rich source of bioactive secondary metabolites. In our initial study, 40 Diaporthe isolates were analyzed for their metabolite production. A total of 153 compounds were identified based on their spectroscopic properties-Ultraviolet-visible and mass spectrometry. From these, 43 fungal metabolites were recognized as potential chemotaxonomic markers, mostly belonging to the drimane sesquiterpenoid-phthalide hybrid class. This group included mainly phytotoxic compounds such as cyclopaldic acid, altiloxin A, B, and their derivatives. To the best of our knowledge, this is the first report on the metabolomic studies on Diaporthe eres species complex from fruit trees in the South-Eastern Poland. The results from our study may provide the basis for the future research on the isolation of identified metabolites and on their bioactive potential for agricultural applications as biopesticides or biofertilizers.

Changes in the size and electrophoretic mobility of HDL subpopulation particles in chronic kidney disease.

BACKGROUND: High-density lipoprotein (HDL) is a heterogeneous group of particles with anti-atherogenic properties whose metabolism is alterated in chronic kidney disease (CKD). The aim of this study was to evaluate the particle size and mobility of HDL subpopulations in non-dialysis CKD patients. METHODS: The study involved 42 non-dialysis CKD patients (stages 3a-4) and 18 control subjects. HDL was separated by non-denaturing two-dimensional polyacrylamide gradient gel electrophoresis (2D-PAGGE) and eight HDL subpopulations; preß1, preß2a-c, and α1-4 were distinguished. The size and electrophoretic mobility of HDL subpopulation particles were compared between the groups, and a regression analysis was conducted. RESULTS: In CKD patients, the mean sizes of α-HDL and preß2-HDL particles were significantly lower compared to the control group (8.42 ± 0.32 nm vs. 8.64 ± 0.26 nm, p = 0.014; 11.45 ± 0.51 vs. 12.34 ± 0.78 nm, p = 0.003, respectively). The electrophoretic mobility of preß2-HDL relative to α-HDL was significantly higher in CKD patients compared to the control group (Rf 0.65 ± 0.06 vs. 0.53 ± 0.10, p = 0.002). The size and mobility of HDL subpopulations correlated with eGFR values (p < 0.01). These relationships remained statistically significant after adjusting for age, gender, statin treatment, apolipoprotein AI, total cholesterol, and triglyceride levels. DISCUSSION: CKD affects the size and mobility of HDL particles, which can be related to HDL dysfunction. The magnitude of HDL size and mobility changes depended on CKD stage and differed for individual HDL subpopulations, which indicates that some stages of HDL metabolism may be more affected by the presence of chronic kidney disease.

Effect of COVID-19 on Kidney Graft Function One Year after Onset.

Background and Objectives: Kidney transplant recipients (KTRs) are at a higher risk of severe COVID-19 development. The course of the infection may vary. Long-term consequences for graft function are still being studied. We investigate whether the clinical course of SARS-CoV-2 infection among KTRs had a long-term effect on graft function. Patients and method: 128 KTRs with confirmed SARS-CoV-2 infection were included in the study. They were divided into two groups: mild (without the need for oxygen therapy; n = 91) and severe (with the need for oxygen therapy; n = 21). Baseline characteristics and medical data, especially creatinine level, estimated glomerular filtration rate (eGFR) CKD-EPI, and proteinuria, were analyzed. The main outcomes were the absolute and relative change in eGFR during the one-year follow-up after COVID-19. In the final models, sex, age, smoking, presence of diabetes mellitus (DM), and cardiovascular disease (CVD) were included. Results: KTRs with severe COVID-19 were older, more likely to smoke, and had DM and CVD more frequently. Our analysis reveals that COVID-19 severity was associated with a significantly more pronounced relative eGFR decline one year after recovery only in males [-13.94 (95% CI: -25.13 to -2.76, p = 0.015) percentage points]. One year after the disease onset, males with a severe course of the infection had a higher eGFR decline than those with a mild one. The COVID-19 severity did not affect eGFR loss in females. Conclusions: In KTRs suffering from COVID-19, deterioration of graft function was noticed. The eGFR decline was associated with disease severity and sex. It indicates a need for further research, observation, and preventive actions for KTRs, especially males.

Screening for Polyomavirus Viruria Like Early Detection of Human Polyomavirus Infection and Replication: The Results of a Single-Center Observation.

BACKGROUND: Polyomavirus (PV) infection and PV-associated nephropathy (PVAN) are some of the most important problems in kidney transplantation. PURPOSE: Our objective was to determine the incidence of PV viruria and PV replication in single-center Polish kidney transplant recipients (KTR). METHODS: Urine samples from 155 cadaveric KTR were analyzed for PV viruria using quantitative real-time polymerase chain reaction and the patients were followed prospectively. The PV replication was recognized when the urine level was >107 PV DNA copies/mL of urine. RESULTS: Based on the PV DNA analysis, the patients were divided into 3 groups: Group 1 (n = 87; 56.1%) without viruria, Group 2 (n = 44; 28.4%) with viruria but without PV replication, and Group 3 (n =24; 15.5%) with PV replication. The presence of PV viruria was correlated with the type of immunosuppressive regimen, strongly associated with tacrolimus intake. There was no correlation between viruria and mycophenolate daily dose in the study population. In Group 3 there were 6 patients (3.9%) with high viruria (>1010 copies/mL), and 5 patients from this group had confirmed PVAN in allograft biopsy. CONCLUSIONS: The prevalence of BK virus infection in KTR is similar to that reported in studies from other countries. We confirmed that PV viruria can be both a good screening for PV infection and a good predictor of PVAN. Tacrolimus was the most important predictor of PV viruria and PV replication in KTR.

Changes in Kidney Graft Function in COVID-19 Convalescents.

BACKGROUND: Kidney transplant recipients (KTRs) are at an increased risk of infection with severe acute respiratory syndrome coronavirus 2, with mortality from 13% to over 30%. However, data concerning the influence of COVID-19 on long-term graft function in convalescents is lacking. The aim of this study was to evaluate the influence of COVID-19 on graft function at 6 months after recovery. METHODS: A longitudinal controlled study was conducted in a group of 1058 KTRs. Of 180 patients with COVID-19 in the past, 77 KTRs (45 male) with a mean age 50.57 ± 13.37 years, Charlson Comorbidity Index of 3 (median; interquartile range [IQR], 3-5), Fragility Score of 3 (median; IQR, 3-3), and minimum 6 months after acute COVID-19 were included. The most common symptoms were weakness (75.33%), fever (74.03%), cough (51.95%), and loss of appetite (48.05%). Thirty-three patients were hospitalized; none required invasive ventilation therapy, but 16 required oxygen support. The treatment of COVID-19 included antibiotics (38.96%), thromboprophylaxis (25.97%), and nonsteroidal anti-inflammatory drugs, or paracetamol (25.97%). RESULTS: The median (IQR) values of serum creatinine 3 months before the onset and 6 months after COVID-19 were 1.25 (0.98-1.86) and 1.26 (1.03-1.78) mg/dL (nonsignificant difference); in strata analysis, there were also no differences with regards to patients with higher and lower comorbidity (3 < Charlson Comorbidity Index < 3) and fragility (3 < Fragility Score < 3). Furthermore, creatinine concentration in KTRs and controls did not differ. CONCLUSIONS: In the group of KTRs with a mild course of COVID-19, no negative impact of the infection on graft function was observed 6 months after transplantation.

Associations between symptoms of constipation and sleep quality in patients with nondialysis chronic kidney disease: a cross-sectional study.

INTRODUCTION Sleep disturbances, similarly to constipation­related symptoms, are common problems in patients with chronic kidney disease (CKD) and are associated with worse health-related quality of life. OBJECTIVES The aim of the study was to investigate sleep problems in conservatively treated patients with CKD and to assess association between sleep quality and constipation in that population. PATIENTS AND METHODS In this cross­sectional study, 100 conservatively treated outpatients with CKD filled questionnaires addressing sleep quality (The Medical Outcomes Study 12­item Sleep Scale-Revised [MOS­Sleep­R]) and constipation­related symptoms (PAC­SYM, Rome III criteria). RESULTS The T scores of none of the assessed sleep domains differed across the estimated glomerular filtration rate terciles (all P >0.05). The scores from the PAC-SYM abdominal and stool subscales correlated with all assessed sleep quality domains. In both univariable and multivariable regression models adjusted for key clinical data, functional constipation, less than 7 bowel movements a week, abdominal discomfort, and pain as well as too small bowel movements were independently associated with increased prevalence ratio of decreased sleep quality. CONCLUSIONS In patients with nondialysis CKD, sleep disorders might have common etiological factors with constipation-related symptoms.

New Cladosporium Species from Normal and Galled Flowers of Lamiaceae.

A series of isolates of Cladosporium spp. were recovered in the course of a cooperative study on galls formed by midges of the genus Asphondylia (Diptera, Cecidomyidae) on several species of Lamiaceae. The finding of these fungi in both normal and galled flowers was taken as an indication that they do not have a definite relationship with the midges. Moreover, identification based on DNA sequencing showed that these isolates are taxonomically heterogeneous and belong to several species which are classified in two different species complexes. Two new species, Cladosporium polonicum and Cladosporium neapolitanum, were characterized within the Cladosporium cladosporioides species complex based on strains from Poland and Italy, respectively. Evidence concerning the possible existence of additional taxa within the collective species C. cladosporioides and C. pseudocladosporioides is discussed.

Non-HDL-C/TG ratio indicates significant underestimation of calculated low-density lipoprotein cholesterol (LDL-C) better than TG level: a study on the reliability of mathematical formulas used for LDL-C estimation.

OBJECTIVES: Low-density lipoprotein cholesterol (LDL-C) is the main laboratory parameter used for the management of cardiovascular disease. The aim of this study was to compare measured LDL-C with LDL-C as calculated by the Friedewald, Martin/Hopkins, Vujovic, and Sampson formulas with regard to triglyceride (TG), LDL-C and non-high-density lipoprotein cholesterol (non-HDL-C)/TG ratio. METHODS: The 1,209 calculated LDL-C results were compared with LDL-C measured using ultracentrifugation-precipitation (first study) and direct (second study) methods. The Passing-Bablok regression was applied to compare the methods. The percentage difference between calculated and measured LDL-C (total error) and the number of results exceeding the total error goal of 12% were established. RESULTS: There was good correlation between the measurement and calculation methods (r 0.962-0.985). The median total error ranged from -2.7%/+1.4% (first/second study) for Vujovic formula to -6.7%/-4.3% for Friedewald formula. The numbers of underestimated results exceeding the total error goal of 12% were 67 (Vujovic), 134 (Martin/Hopkins), 157 (Samspon), and 239 (Friedewald). Less than 7% of those results were obtained for samples with TG >4.5 mmol/L. From 57% (Martin/Hopkins) to 81% (Vujovic) of underestimated results were obtained for samples with a non-HDL-C/TG ratio of <2.4. CONCLUSIONS: The Martin/Hopkins, Vujovic and Sampson formulas appear to be more accurate than the Friedewald formula. To minimize the number of significantly underestimated LDL-C results, we propose the implementation of risk categories according to non-HDL-C/TG ratio and suggest that for samples with a non-HDL-C/TG ratio of <1.2, the LDL-C level should not be calculated but measured independently from TG level.

The relation of fibromyalgia and fibromyalgia symptoms to self-reported seizures.

OBJECTIVE: Several epidemiological and clinical reports associate fibromyalgia (FM) with seizure disorders, and clinical studies associate FM diagnosis with psychogenic non-epileptic seizures. However, these associations rely on self-reports of being diagnosed with FM or unstandardized clinical diagnosis in combination with small samples. We investigated the association of FM and self-reported seizures using a large rheumatic disease databank and the current established self-reported, symptom-based FM diagnostic criteria. METHODS: We selected a random observation from 11,378 subjects with rheumatoid arthritis (RA), 2,390 (21.0%) of whom satisfied 2016 revised criteria for FM. Patients were inquired about the presence of any kind of seizures in the previous 6 months, anti-epileptic medications, and patient-reported symptoms and outcomes. RESULTS: Seizures were reported by 89 RA patients who met FM criteria (FM+) and by 97 patients who did not (FM-), resulting in an age- and sex-adjusted seizure prevalence of 3.74 (95% CI 2.95 to 4.53) per 100 FM+ subjects and 1.08 (95% CI 0.87 to 1.30) in FM- subjects. The seizure odds ratio of FM+ to FM- cases was 3.54 (95% CI 2.65 to 4.74). Seizures were associated to a very similar degree with symptom reporting (somatic symptom count and comorbidity index) as to FM diagnosis variables. RA patients reporting seizures also reported worse pain, quality of life, and functional status. Seizure patients treated with anti-seizure medication had worse outcomes and more comorbidities than seizure patients with no seizure drugs. CONCLUSIONS: We found a significant and similar association of both FM diagnostic variables and FM-related symptom variables, including the number of symptoms and comorbidities, with self-reported seizures in people with RA. The observed association was similar to those found in previous studies of symptoms variables and seizures and does not suggest a unique role for fibromyalgia diagnosis. Rather, it suggests that multi-symptom comorbidity is linked to seizures in a complex and not yet clearly understood way. As the current study relied on self-reported seizures and was not able to distinguish between epileptic and psychogenic nonepileptic seizures, future studies are needed to replicate the findings using both validated FM criteria assessments and clinically verified diagnoses of epileptic and psychogenic seizures.

Constipation and the Quality of Life in Conservatively Treated Chronic Kidney Disease Patients: A Cross-sectional Study.

Background: Constipation is a common gastrointestinal disorder that in general population is associated with worse health-related quality of life (HRQoL). The epidemiology of constipation has not been reliably determined in conservatively-treated CKD patients. We aimed to determine the prevalence of constipation and constipation-related symptoms in conservatively-treated CKD patients, to find factors associated with their altered prevalence ratio (PR), and to verify the associations between constipation and HRQoL. Methods: In this cross-sectional study, 111 conservatively-treated CKD outpatients fulfilled questionnaires that included questions addressing HRQoL (SF-36v2®), constipation-related symptoms (The Patient Assessment of Constipation-Symptoms questionnaire), the Bristol stool form scale (BSFS), Rome III criteria of functional constipation (FC), and frequency of bowel movement (BM). Results: Depending on the used definition, the prevalence of constipation was 6.6-28.9%. Diuretics and paracetamol were independently associated with increased PR of BSFS-diagnosed constipation (PR 2.86, 95% CI 1.28-6.37, P = 0.01) and FC (PR 2.67, 95% CI 1.07-6.64, P = 0.035), respectively. The most commonly reported symptoms were bloating (50.9%) and straining to pass a BM (42.7%). Abdominal discomfort (37.3%) was independently associated with worse scores in all analyzed HRQoL domains. In multiple regressions, FC and having <7 BM/week, but not BSFS-diagnosed constipation, were associated with lower scores in several HRQoL domains. Conclusions: Constipation and related symptoms are prevalent in CKD patients. FC and decreased frequency of defecation, but not BSFS-diagnosed constipation, are associated with worse assessment of HRQoL in conservatively-treated CKD patients.

Gastrointestinal Pathologies in Patients After Successful Renal Transplantation.

BACKGROUND: Kidney transplantation (KT) is the most desired and cost-effective modality of renal replacement therapy for patients with chronic kidney failure. KT protects the patient from complications that may develop during chronic dialysis. Unfortunately, evidence also suggests that KT patients are more prone to developing cancer than healthy persons. Many complications after renal transplantation can be prevented if they are detected early. The aim of this study was to evaluate the prevalence of gastrointestinal pathologies in patients after KT. METHODS: Adult patients after KT who are under the care of the Outpatient Department of Nephrology at the Medical University of Gdansk, Poland, received alarm symptom questionnaires and referral for testing for the presence of fecal occult blood. Then, in 58 selected patients (36 men and 22 women), endoscopic examination was performed. Mean age was 57.34 ± 10.1 (range, 35-83) years. RESULTS: Out of 940 patients after KT, resting under supervision of the Outpatient Department, 208 patients completed the questionnaire and 118 gave a stool sample for testing: 40 results were positive. After analyzing the questionnaires and stool results, 100 patients qualified for further investigation. The endoscopic examination had been performed so far in 58 patients and revealed gastritis and/or duodenitis in 49 patients, diverticular colon disease in 26, esophagitis in 8, colon polyps in 16, stomach polyps in 4, inflammatory bowel disease in 12, and cancers in 3. CONCLUSIONS: The preliminary results indicate that patients after KT have significant risk of gastrointestinal pathologies and require detailed diagnostic endoscopy.

Pregnancy After Kidney Transplantation With Maternal and Pediatric Outcomes: A Single-Center Experience.

Outcomes of pregnancies after kidney transplantation were evaluated. Thirty-one pregnancies in 26 women were noted. The mean maternal age at pregnancy was 31 ± 5 years (range, 23-44 years). The interval between transplantation and conception was 54 ± 51 months (range, 7-213 months). The mean serum creatinine concentration before conception was 1.28 ± 0.4 mg/dL (range, 0.8-2.45 mg/dL), and mean estimated glomerular filtration rate (Chronic Kidney Disease Epidemiology Collaboration) was 62 ± 18 mL/min/1.73 m2 (range, 27-106 mL/min/1.73 m2). There were no maternal deaths. There was 1 case of suspected acute rejection after delivery. There was 1 case of graft loss during pregnancy. Maternal complications included edema (6/26), hypertension (7/26), increase of (2/26) or appearance of proteinuria (5/26), and preeclampsia (4/26). Mean creatinine increase during pregnancy was 0.02 mg/dL. Mean creatinine 1 year after pregnancy was 1.54 mg/dL (±0.8 mg/dL). There were 19 cesarean sections. Fetal outcomes included 25 live births, 4 abortions, and 2 stillbirths. Out of 25 live births, 22 children were considered healthy, 2 children had congenital defects, and there were 2 deaths at neonatal age. Mean pregnancy age was 35 ± 4 weeks (range, 24-40 weeks). The rate of premature deliveries was 15 of 25. Mean neonate birth weight was 2363 ± 1029 grams (range, 490-4100 grams). The rate of babies small for gestational age was 19%. During follow-up (range, 0.5-30 years) 5 of 26 patients lost grafts (between 3 and 15 years after pregnancy); most (20) of the children previously considered healthy had good long-term development. Our results confirm that risk of pregnancy in kidney transplant recipients can be accepted, and children considered healthy at delivery develop well.

Plasma Levels of Preß1-HDL Are Significantly Elevated in Non-Dialyzed Patients with Advanced Stages of Chronic Kidney Disease.

In chronic kidney disease (CKD), the level of high-density lipoprotein (HDL) decreases markedly, but there is no strong inverse relationship between HDL-cholesterol (HDL-C) and cardiovascular diseases. This indicates that not only the HDL-C level, but also the other quantitative changes in the HDL particles can influence the protective functionality of these particles, and can play a key role in the increase of cardiovascular risk in CKD patients. The aim of the present study was the evaluation of the parameters that may give additional information about the HDL particles in the course of progressing CKD. For this purpose, we analyzed the concentrations of HDL containing apolipoprotein A-I without apolipoprotein A-II (LpA-I), preß1-HDL, and myeloperoxidase (MPO), and the activity of paraoxonase-1 (PON-1) in 68 patients at various stages of CKD. The concentration of HDL cholesterol, MPO, PON-1, and lecithin-cholesterol acyltransferase (LCAT) activity were similar in all of the analyzed stages of CKD. We did not notice significant changes in the LpA-I concentrations in the following stages of CKD (3a CKD stage: 57 ± 19; 3b CKD stage: 54 ± 15; 4 CKD stage: 52 ± 14; p = 0.49). We found, however, that the preß1-HDL concentration and preß1-HDL/LpA-I ratio increased along with the progress of CKD, and were inversely correlated with the estimated glomerular filtration rate (eGFR), even after adjusting for age, gender, triacylglycerols (TAG), HDL cholesterol, and statin therapy (ß = -0.41, p < 0.001; ß = -0.33, p = 0.001, respectively). Our results support the earlier hypothesis that kidney disease leads to the modification of HDL particles, and show that the preß1-HDL concentration is significantly elevated in non-dialyzed patients with advanced stages of CKD.

Apolipoprotein E gene polymorphism and renal function are associated with apolipoprotein E concentration in patients with chronic kidney disease.

BACKGROUND: Chronic kidney disease (CKD) associates with complex lipoprotein disturbances resulting in high cardiovascular risk. Apolipoprotein E (APOE) is a polymorphic protein with three common isoforms (E2; E3; E4) that plays a crucial role in lipoprotein metabolism, including hepatic clearance of chylomicrons and very low-density lipoprotein (VLDL) remnants, and reverse cholesterol transport. It demonstrates anti-atherogenic properties but data concerning the link between polymorphism and level of APOE in CKD patients are inconclusive. The aim of our research was to assess the relationship between APOE gene polymorphism and APOE concentration and its redistribution among lipoproteins along with CKD progression. METHODS: 90 non-dialysed CKD patients were included into the study. Real time PCR was used for APOE genotyping. APOE level was measured in serum and in isolated lipoprotein fractions (VLDL; IDL + HDL; HDL). Kidney function was assessed using eGFR CKD-EPI formula. RESULTS: The population was divided into three APOE genotype subgroups: E2(ε2ε3), E3(ε3ε3) and E4(ε3ε4). The highest APOE level was observed for the E2 subgroup (p < 0.001). APOE concentration positively correlated with eGFR value in the E2 subgroup (r = 0.7, p < 0.001) but inversely in the E3 subgroup (r = - 0.29, p = 0.02).). A lower concentration of APOE in the E2 subgroup was associated with its diminished contents in HDL and IDL + LDL particles. In the E3 subgroup, the higher concentration of APOE was related to the increased number of non-HDL lipoproteins. CONCLUSION: In patients with CKD, APOE genotype as well as renal function are associated with the concentration of APOE and its redistribution among lipoprotein classes.

Progression of Chronic Kidney Disease Affects HDL Impact on Lipoprotein Lipase (LPL)-Mediated VLDL Lipolysis Efficiency.

BACKGROUND/AIMS: Hypertriglyceridaemia (HTG) and reduction and dysfunction of high density lipoprotein (HDL) are common lipid disturbances in chronic kidney disease (CKD). HTG in CKD is caused mainly by the decreased efficiency of lipoprotein lipase (LPL)-mediated very low density lipoprotein triglyceride (VLDL-TG) lipolysis. It has not been clarified whether HDL dysfunction in CKD contributes directly to HTG development; thus, the aim of this study was to assess the impact of CKD progression on the ability of HDL to enhance LPL-mediated VLDL-TG lipolysis efficiency. METHODS: VLDL was isolated from non-dialysis patients in CKD stages 3 and 4 and from non-CKD patients. The VLDL was incubated with LPL at the constant LPL:VLDL-TG ratio, in the absence or presence of HDL. After incubation, the VLDL was separated and the percentage (%) of hydrolyzed TG was calculated. RESULTS: HDL presence increased the lipolysis efficiency of VLDL isolated from CKD and non-CKD patients, for the VLDL-TG> 50 mg/dl. Its effect was dependent on the VLDL-TG and HDL-cholesterol concentrations in the reaction mixtures: the higher the concentrations of VLDL-TG and HDL-cholesterol, the greater the effect. The positive impact of HDL on VLDL lipolysis was modified by CKD progression: the percentage of lipolyzed VLDL-TG in the presence of HDL decreased with a reduction in eGFR (r=0.43, p=0.009), and for patients with stage 4 CKD, no positive impact of HDL on lipolysis was observed. The percentage of lipolyzed TG correlated negatively with apoE and apoCs content in VLDL, and positively with HDL-apoCII, as well as with VLDL and HDL apoCII/ apoCIII ratios. The progression of CKD was associated with unfavourable changes in VLDL and HDL composition; apoE and apoCs levels increased in VLDL with a decrease in eGFR whereas the HDL-cholesterol level decreased. CONCLUSION: The progression of CKD affects lipoprotein composition and properties, and modulates the positive impact of HDL on VLDL lipolysis efficiency. In CKD patients, HDL deficiency and dysfunction can directly affect hypertriglyceridaemia development.

Analysis of preoperative blood platelet parameters in terms of diversity of epithelial ovarian cancer.

Smouldering inflammation, thrombocytosis, and platelet hyper-reactivity are linked to malignancy. The relationships between preoperative diagnostic blood morphology parameters and cancer have been the focus of much interest, because some of these parameters are correlated with advanced cancer stages and poor patient survival rates. This study aimed to perform an observational, retrospective analysis of the intradiversity of blood platelet parameters in patients with different International Federation of Gynaecology and Obstetrics (FIGO) stages and different histological types of epithelial ovarian carcinomas (EOC), and also an analysis of the overall survival rate.In all, 94 EOC patients were included in this analysis (23 mucinous, 33 serous, 20 undifferentiated, 14 endometrioid, and 4 clear cell carcinoma cases). Peripheral blood samples were collected and analyzed before drug or surgical treatment.The platelet-to-neutrophil ratio (PNR) was related to the histological type of EOC, particularly mucinous carcinoma. In patients with mucinous cancer, the PNR was significantly lower compared with patients with nonmucinous cancer, and this parameter distinguished between mucinous and nonmucinous groups of patients (area under receiver-operating characteristic [ROC] curve 0.721 ±â€Š.056; sensitivity 82.6%; specificity 61%; P < .001; ROC analysis), regardless of the FIGO stage. Moreover, elevated PNR values were correlated with lower survival rate of EOC patients.The reduced PNR, similar to the lower level of cancer antigen 125, is characteristic for mucinous ovarian carcinoma patients. Moreover, elevated PNR index might correlate with poor survival of patients.

An assessment of health status and health behaviours in adolescents: main points and methods of the SOPKARD-Junior programme.

INTRODUCTION: The study involved preparing and implementation a model of complex screening programme for adolescents and comparison of anthropometric examinations between the population of the SOPKARD-Junior programme and representative sample of Polish children in the same age. MATERIAL AND METHODS: The screening programme in 14-15 year old pupils (n = 282) included: anthropometric, blood pressure, echocardiographic, electrocardiographic, carotid arteries, kidney and thyroid ultrasound examinations, as well as respiratory, dental and masticatory system, orthopaedic, psychological and psychiatric assessment. Blood and urine tests were also performed. The results of anthropometric examinations from the SOPKARD-Junior and OLAF programmes were used for comparative analysis. RESULTS: Statistically significant (p < 0.001) differences between young people from Sopot and their peers in the general Polish population were found in height (+3.61 cm for boys), body mass (+5.19 kg for boys and +3.99 kg for girls), body mass index (+0.99 kg/m2 for boys and +1.33 kg/m2 for girls), waist circumference (+4.52 cm for boys and +4.52 cm for girls) and hip circumference (+2.51 cm for boys). The highest attendance rate was achieved for examinations performed in school (e.g. anthropometric and blood pressure measurements - n = 268; 95%) and the lowest for the echocardiograpy performed in local hospital (n = 133; 47%). The mean score of the programme quality (scale 1-6) assessed by children was 4.63. CONCLUSIONS: The SOPKARD-Junior programme represents an attempt to develop a model of screening assessments for teenagers in Poland. Preliminary results of the SOPKARD-Junior programme indicate small differences in the biological development of Sopot youth in comparison with their peers from Polish population of the OLAF programme. The high attendance rate on research conducted at the school indicate that proposed health examinations in adolescents are acceptable and feasible.
