Biomolecular evidence reveals mares and long-distance imported horses sacrificed by the last pagans in temperate Europe.

Horse sacrifice and deposition are enigmatic features of funerary rituals identified across prehistoric Europe that persisted in the eastern Baltic. Genetic and isotopic analysis of horses in Balt cemeteries [1st to 13th centuries CE (Common Era)] dismantle prevailing narratives that locally procured stallions were exclusively selected. Strontium isotope analysis provides direct evidence for long-distance (~300 to 1500 kilometers) maritime transport of Fennoscandian horses to the eastern Baltic in the Late Viking Age (11th to 13th centuries CE). Genetic analysis proves that horses of both sexes were sacrificed with 34% identified as mares. Results transform the understanding of selection criteria, disprove sex-based selection, and elevate prestige value as a more crucial factor. These findings also provide evidence that the continued interaction between pagans and their newly Christianized neighbors sustained the performance of funerary horse sacrifice until the medieval transition. We also present a reference 87Sr/86Sr isoscape for the southeastern Baltic, releasing the potential of future mobility studies in the region.

Biomedical knowledge of dementia is not enough to counteract its stigma - quantitative research among future medical and social care staff in Poland.

OBJECTIVES: The aim is to assess the level of stigmatization and knowledge of dementia among university students of medical, rehabilitation and social faculties in Poland. Possible correlates of these concepts and group differences are also investigated. METHODS: We applied quantitative methods using an online questionnaire comprising sociodemographics, the Alzheimer's Disease Knowledge Scale, a vignette of a person with dementia and the modified Family Stigma in Alzheimer's Disease Scale. RESULTS: Students had low levels of dementia knowledge and moderate levels of stigma. Medical science students had significantly better knowledge than the other groups but did not differ in their level of stigma. Relationships between the main variables were complex. Emotional and cognitive stigmatizing attributions were negatively correlated with knowledge about communication and behaviors of people with dementia. Better knowledge on causes and characteristics, as well as on risks and health promotion of the disease also triggered fewer negative attributions toward people with dementia. CONCLUSIONS: If health-related programs are to be effective, they should provide opportunities for the acquisition of relevant knowledge and skills that also address the stigmatization of people living with dementia. Well-established biomedical knowledge on dementia must be supplemented with a person-centered approach and proper communication skills.

Artificial Intelligence-Based Emphysema Quantification in Routine Chest Computed Tomography: Correlation With Spirometry and Visual Emphysema Grading.

OBJECTIVE: The aim of the study is to assess the correlation between artificial intelligence (AI)-based low attenuation volume percentage (LAV%) with forced expiratory volume in the first second to forced vital capacity (FEV1/FVC) and visual emphysema grades in routine chest computed tomography (CT). Furthermore, optimal LAV% cutoff values for predicting a FEV1/FVC < 70% or moderate to more extensive visual emphysema grades were calculated. METHODS: In a retrospective study of 298 consecutive patients who underwent routine chest CT and spirometry examinations, LAV% was quantified using an AI-based software with a threshold < -950 HU. The FEV1/FVC was derived from spirometry, with FEV1/FVC < 70% indicating airway obstruction. The mean time interval of CT from spirometry was 3.87 ± 4.78 days. Severity of emphysema was visually graded by an experienced chest radiologist using an established 5-grade ordinal scale (Fleischner Society classification system). Spearman correlation coefficient between LAV% and FEV1/FVC was calculated. Receiver operating characteristic determined the optimal LAV% cutoff values for predicting a FEV1/FVC < 70% or a visual emphysema grade of moderate or higher (Fleischner grade 3-5). RESULTS: Significant correlation between LAV% and FEV1/FVC was found (ϱ = -0.477, P < 0.001). Increasing LAV% corresponded to higher visual emphysema grades. For patients with absent visual emphysema, mean LAV% was 2.98 ± 3.30, for patients with trace emphysema 3.22 ± 2.75, for patients with mild emphysema 3.90 ± 3.33, for patients with moderate emphysema 6.41 ± 3.46, for patients with confluent emphysema 9.02 ± 5.45, and for patients with destructive emphysema 16.90 ± 8.19. Optimal LAV% cutoff value for predicting a FEV1/FVC < 70 was 6.1 (area under the curve = 0.764, sensitivity = 0.773, specificity = 0.665), while for predicting a visual emphysema grade of moderate or higher, it was 4.7 (area under the curve = 0.802, sensitivity = 0.766, specificity = 0.742). Furthermore, correlation between visual emphysema grading and FEV1/FVC was found. In patients with FEV1/FVC < 70% a high proportion of subjects had emphysema grade 3 (moderate) or higher, whereas in patients with FEV1/FVC ≥ 70%, a larger proportion had emphysema grade 3 (moderate) or lower. The sensitivity for visual emphysema grading predicting a FEV1/FVC < 70% was 56.3% with an optimal cutoff point at a visual grade of 4 (confluent), demonstrating a lower sensitivity compared with LAV% (77.3%). CONCLUSIONS: A significant correlation between AI-based LAV% and FEV1/FVC as well as visual CT emphysema grades can be found in routine chest CT suggesting that AI-based LAV% measurement might be integrated as an add-on functional parameter in the evaluation of chest CT in the future.

Patients' Expectations and Satisfaction with the Patient-Doctor Relationship in Hidradenitis Suppurativa.

INTRODUCTION: Hidradenitis suppurativa (HS) is a chronic inflammatory dermatosis with a vast psychosocial burden. We analyzed the actual and ideal patient-doctor relationship and patients' satisfaction with the patient-doctor relationship in relation to their satisfaction with life (SWL), HS-related quality of life, and psychopathological symptoms. METHODS: 105 HS patients (53% females; mean age 37.64 ± 14.01 years) were enrolled. Severity of the disease was measured using Hurley staging and the International HS Score System (IHS4). Instruments utilized: Patient Expectation Test; Satisfaction with Life Scale; HS Quality of Life; Patient Health Questionnaire-9; Generalized Anxiety Disorder-7; General Health Questionnaire. RESULTS: Patients with Hurley I and mild IHS4 had the lowest satisfaction with the patient-doctor relationship. There were significant correlations between the actual patient-doctor relationship and the patients' SWL (r = 0.30; p = 0.002), depressive (r = -0.36; p < 0.01), anxiety (r = 0.37; p < 0.01) and psychopathological symptoms (r = -0.47; p < 0.0001) and between the satisfaction with the patient-doctor relationship and their SWL (r = -0.32; p = 0.00098). Multiple regression analysis revealed a significant influence of the following factors: Hurley II + III, psychopathological symptoms, and severe anxiety about the actual patient-doctor relationship and the satisfaction with the patient-doctor relationship. CONCLUSIONS: Assessment of relations between patients and doctors is related to the patients' mental health and SWL. The usage of the Patient Expectation Test in clinical practice can improve the patient-doctor relationship and the general quality of care for and compliance by HS patients.

Sociodemographic and behavioral factors associated with controlled hypertension after 9 years of observation of a PURE Poland cohort study.

Introduction: Despite some improvement in awareness and treatment of hypertension, blood pressure control is still below expectations in Poland. The aim of the study was to analyze the secular trend of hypertension prevalence in the PURE Poland cohort study over 9 years of observation and to analyze factors associated with controlled HT. Methods: The study group consisted of 1,598 participants enrolled in a Prospective Urban and Rural Epidemiological Study (PURE), who participated both in baseline (2007-2010) and 9-year follow-up (2016-2019). Hypertension was ascertained on the basis of (1) self-reported hypertension previously diagnosed by the physician, (2) self-reported anti-hypertensive medication, and/or (3) an average of two blood pressure measurements ≥140 mmHg systolic BP and/or ≥90 mmHg diastolic BP. Results: The prevalence of hypertension increased from 69.4% at baseline to 85.9% at 9-year follow-up. The chance of HT was 8.6-fold higher in the oldest vs. the youngest age group [OR 8.55; CI 4.47-16.1]. Male sex increased the chance for hypertension over 3-fold [OR 3.23; CI 2.26-4.73]. Obesity, according to BMI, increased the chance of HT 8-fold [OR 8.01; CI 5.20-12.8] in comparison with normal body weight. Male sex decreased the chance of controlled HT after 9 years [OR 0.68; CI 0.50-0.92]. There was no statistically significant association between controlled HT and age or place of residence. Higher and secondary education increased the chance of controlled HT over 2-fold in comparison with primary education [OR 2.35; CI 1.27-4.34, OR 2.34; CI 1.33-4.11]. Obesity significantly decreased the chance of controlled HT after 9 years in comparison with normal body weight [OR 0.54; CI 0.35-0.83]. Conclusion: Factors significantly increasing the chance for controlled hypertension after 9 years were female sex, secondary and tertiary education, normal body weight, and avoiding alcohol drinking. Changes in lifestyle, with special emphasis on maintaining normal body weight, should be the basis of prevention and control of HT.

Influence of contrast agent on artificial intelligence-based CT low attenuation volume percentage measurement.

BACKGROUND: Low attenuation volume percentage (LAV%) has been identified as a quantitative imaging biomarker for emphysema with good correlation with spirometry. The influence of intravenous contrast agent on LAV% and its correlation with spirometry is not well known. PURPOSE: To evaluate the influence of intravenous contrast agent on artificial intelligence (AI)-based LAV% in correlation with spirometric Tiffeneau-Pinelli Index (TI). MATERIAL AND METHODS: In a retrospective study, two groups of 47 patients (mean age 68.04 ± 12.64 and 67.89 ± 11.54 years) with either non-enhanced chest computed tomography (CT) or contrast-enhanced CT were compared. Using an AI-based software, LAV% was quantified using a threshold <-950 HU. TI was calculated from spirometry and pathologic airway obstruction was considered with a TI <70. The effect of contrast agent on LAV% and the relationship between TI and LAV% was analyzed. Correlation coefficients between TI and LAV% were compared for both groups. RESULTS: Patients with non-enhanced CT had a mean LAV% of 9.07 ± 7.53. Of them, 22 patients had a TI <70% and 25 patients a TI ≥70%. Patients with contrast-enhanced CT had a mean LAV% of 6.54 ± 4.62. Of them, 20 patients had a TI <70% and 27 patients had a TI ≥70%. Contrast agent did not show a major effect on LAV% (P = 0.099) and the relationship between TI and LAV% (P = 0.88). In both groups, a significant correlation between TI and LAV% was found (ρ = -0.317 for non-enhanced CT; ρ = -0.514 for contrast-enhanced CT). Difference between correlation coefficients was insignificant. CONCLUSION: Our findings suggest that contrast agent does not influence LAV% nor its correlation with TI.

Retrospective Evaluation of the Most Frequently Observed Histological Changes in Duodenal and Rectal Mucosal Biopsies in Horses with Recurrent Colic.

Colic, a condition affecting the gastrointestinal tract of horses, manifests as severe pain and may be a life-threatening condition. It is possible to distinguish between an acute, disposable process, as well as recurrent colic symptoms (abdominal pain) caused by an ongoing chronic inflammatory process. This paper presents a retrospective analysis of the histopathological findings of duodenal and rectal samples taken from horses with recurrent colic, with the aim to determine the frequency and extent of inflammation. The samples, i.e., duodenal biopsy (60 samples) and rectal biopsy (17 samples), were taken from 77 horses showing recurrent colic symptoms. Histopathological examination included staining with hematoxylin and eosin. The examination included evaluation of the superficial epithelium, mucosal lamina propria, and submucosa. All samples from the duodenum and rectum showed the presence of leukocyte infiltration in the mucosal lamina propria. The most frequently observed cellular infiltration was a moderate infiltration consisting of lymphocytes and plasma cells in duodenum and mixed populations of plasma cells, lymphocytes, and eosinophilia in the rectum. Mott cells were also noted among the inflammatory infiltrates. More than one-fourth of the horses were found to have shortened intestinal villi. The results presented here showed the involvement of inflammation in the course of recurrent colic, which can be both its cause (by impairing motility and absorption) and its effect (as a result of obstruction or ischemia).

Homeostasis of the Intestinal Mucosa in Healthy Horses-Correlation between the Fecal Microbiome, Secretory Immunoglobulin A and Fecal Egg Count.

The defensive function of the intestinal mucosa depends both on the ability to secrete immunoglobulin A and communication with the mucus microbiome. In horses, the functioning of this system is also influenced by the presence of nematode eggs. Feces collected from healthy horses were examined to determine the fecal egg count, immunoglobulin A level (ELISA), microbiome composition (Next-Generation Sequencing, NGS, V3−V4 and V7−V9 hypervariable regions of the 16S rRNA gene analysis and short-chain fatty acid (SCFA) production ((high-performance liquid chromatography, HPLC). In the taxonomic analysis within the phylum, the following order of dominance was found: Firmicutes, Bacteroidota, Verrucomicrobiota and Fibrobacterota. The coefficient of phylogenetic diversity of the microbiome positively correlated with both secretory immunoglobulin A (SIgA) [µg/g of feces] (p = 0.0354, r = 0.61) and SIgA [µg/mg of fecal protein] (p = 0.0382, r = 0.6) and with the number of Cyathostomum eggs (p = 0.0023, r = 0.79). Important components of the key microbiome in horses, such as phylum Proteobacteria and species Ruminococcus flavefaciens, were positively correlated with the fecal SIgA (p < 0.05). All the obtained results indicate the existence of significant relationships between the host response (SIgA production) and composition and SCFA production in the microbiome as well as the presence of small strongyles in the digestive tract of horses.

When Conventional Oxygen Therapy Fails-The Effectiveness of High-Flow Nasal Oxygen Therapy in Patients with Respiratory Failure in the Course of COVID-19.

High-flow nasal oxygen (HFNO) is recommended as a first-line treatment in patients with acute hypoxemic respiratory failure due to COVID-19. We assessed the effectiveness of HFNO and predictors of failure and death. The medical records of 200 consecutive adult patients treated with HFNO were analysed. Ninety-two patients (46%) were successfully cured, 52 (26%) required noninvasive ventilation, and 61 (30.5%) received intubation. Overall mortality was 40.5%. Risk factors of HFNO ineffectiveness were: SpO2 ≤ 90% with conventional oxygen therapy (HR 0.32, 95% CI 0.19-0.53, p < 0.001), SpO2 ≤ 74% without oxygen therapy (HR 0.44, 95% CI 0.27-0.71, p < 0.001), an age ≥ 60, comorbidities, biomarkers (C-reactive protein, procalcitonin, creatinine, lactate dehydrogenase), duration of symptoms before admission to hospital ≤ 9 days, start of treatment with HFNO ≤ 4 days. The multivariate logistic regression models (age ≥ 60, comorbidities, C-reactive protein concentration and SpO2 with oxygen therapy) revealed a high predictive value of death and HFNO failure (AUC 0.851, sensitivity 0.780, specificity 0.802; AUC 0.800, sensitivity 0.776, specificity 0.739, respectively). HFNO is a safe method for treating acute hypoxemic respiratory failure, with effectiveness reaching nearly 50%. Low values of SpO2 without and during oxygen therapy seem to be good diagnostic tools for predicting death and HFNO failure.

Characteristic of FINDRISC Score and Association with Diabetes Development in 6-Year Follow-Up in PURE Poland Cohort Study.

PURPOSE: The aim of the study was to assess if FINDRISC score was associated with diabetes development after 6 years of observation. METHODS: Polish cohort is a part of global PURE study. Hereby analysis presents data from baseline (2007-2010) and 6-year follow-up (2013-2016) and was conducted on 1090 participants (702 women) from urban and rural areas in Lower Silesia region (Poland) without diabetes at the baseline and with complete data throughout course of the study. RESULTS: At the baseline, women had significantly higher FINDRISC score than men (10.43 vs 8.91; p=0.000) and participants from rural areas had higher score than from urban areas (10.97 vs 9.33; p=0.000). At the baseline, 25.87% of the participants had low risk of diabetes according to FINDRISC score, 38.90% had slightly elevated risk, 16.79% moderate risk, 16.42% high risk and 2.02% very high risk. Participants, who were healthy at baseline, but developed diabetes after 6 years of observation had significantly higher FINDRISC, than those who did not (13.39 vs 9.36; p=0.000). In 6-year follow-up, diabetes was diagnosed in 2.8% of participants, who were ascertained to "low risk" according to FINDRISC score in baseline; in 9.9% of participants of "slightly elevated risk", 17.5% of participants of "moderate risk", 26.8% in participants of "high risk" and 50.0% of participants of "very high risk". CONCLUSIONS: Results of PURE Poland cohort study indicates that higher FINDRISC score at the baseline was associated with higher risk of diabetes development during 6 years of observation.

A multi-factorial mathematical model for the selection of electropolishing parameters with a view to reducing the environmental impact.

Electrochemical metal processing is a process that generates harmful pollution. An important goal often disregarded by researchers is not only the achievement of the best possible quality of electropolished surface, but also minimising the load of metal ions in the wastewater generated in the process. The conducted experiments on the electropolishing of stainless steel in laboratory conditions, varied time, temperature and current density conditions, as well as process bath contamination (ranging from 0 to 6% Fe mass) allowed us to develop a multi-factorial mathematical model. This model offers the possibility of being able to select the process parameters recommended for achieving the desired effects. It takes into account such surface quality parameters as roughness and gloss, process duration and current density that determine power consumption, as well as the weight loss of the electropolished element that influence the rate of contamination in processing baths and wastewater. The study presents the composition of a passive film of stainless steel after the electropolishing process at the initial and final stages of the process bath's exploitation. The results obtained from XPS tests were then correlated with the results of corrosion tests and resistance to pitting corrosion in the environment of 0.1 M NaCl.

Personality Factors Crucial in Internalized Stigma Understanding in Psychiatry.

Objective: The main purpose of this research was to establish the relationship between personality traits and internalized stigma in individuals living with severe mental illness. Additionally, the study aimed to identify individual differences that could be used to develop the theoretical socio-cognitive-behavioral equation model of internalized stigma. Methods: A total of 114 patients with diagnosis of nonorganic psychotic disorder or uni- or bipolar affective disorder took part in this study. The Internalized Stigma of Mental Illness (ISMI) scale, Eysenck Personality Questionnaire Revised (EPQ-R) and NEO Five-Factor Inventory (NEO-FFI) were administrated among all participants. Results: Patients presenting higher levels of neuroticism scored higher on the ISMI scale. Otherwise, those with higher levels of extraversion, openness to experience and conscientiousness had lower ISMI scores. With the use of multivariate linear regression, neuroticism, openness to experience and conscientiousness showed the strongest associations with internalized stigma. Conclusions: Intrapersonal factors such as personality traits might explain individual differences in responses to the stigmatization process. Moreover, sociodemographic conditions such as the place of residence and level of education can play a mediating role in reducing the level of internalized stigma. Adequate psychosocial interventions should consider demographics and personality traits when engaging patients with mental illnesses in activities aimed at understanding and accepting the disorders.

Effects of drought on environmental health risk posed by groundwater contamination.

This publication presents a comparison of the content of pollutants in groundwater samples taken at 117 measurement points in four regions of Poland during a drought period and in the reference period without drought. Based on the chemical analyses of water, an assessment of the health risk resulting from the use of underground water for consumption was carried out. The study aimed to determine whether drought affects the increase in health risk exposure of the population. It was found that despite the occurrence of drought, the expected increase in the concentration of pollutants in water does not take place in all locations. This study found that in some cases the occurrence of drought did not cause an increase in the non-cancerogenic threat expressed by the hazard index. There were also no clear changes in excess lifetime cancer risk values except for selected measurement points. On the other hand, the statistical analysis of all data collected in the regions where the research was conducted showed a general trend of increasing environmental health risk caused by changes in groundwater pollution during drought.

Changes in diabetes prevalence and corresponding risk factors - findings from 3- and 6-year follow-up of PURE Poland cohort study.

BACKGROUND: Diabetes mellitus (DM) is one of the greatest challenges for public health worldwide. The aim of the study was the analysis of diabetes development in participants with normoglycemia and Impaired Fasting Glucose (IFG) in 3-year and 6-year follow-up of PURE Poland cohort study. METHODS: The analysis was conducted in Polish cohort enrolled into Prospective Urban and Rural Epidemiology (PURE) Study. The following study presents results of 1330 participants that have partaken both in the baseline study, in 3-year and in the 6-year follow up. The analysis of the impact of risk factors on diabetes development was performed using multivariate Cox frailty analysis. Population Attributable Risk (PAR) was computed individually for every risk factor. RESULTS: Diabetes prevalence increased from 17.7% at baseline to 23.98% in 3-year- and 28.27% in 6-year follow-up. The risk of diabetes was higher in participants with obesity [HR = 5.7, 95%Cl 2,56-12,82], overweight [HR = 3.4, 95%Cl 1,56-7,54] and IFG [HR = 2.7, 95%Cl 1,87-3,85]. The risk of diabetes development was almost 2-fold higher in men than in women [HR = 1.826; 95%CI =1,24 - 2,69]. In 6 years, diabetes developed in 23.8% of participants with IFG and 7.9% of participants with normoglycemia. According to PAR, overweight and obesity accounted for 80.8%, hypertension for 67.6% and IFG for 38.3% of diabetes cases in our population. CONCLUSIONS: Our study reveals alarming increase in prevalence of diabetes during 6 years of observation. In our population, most diabetes cases can be attributed to overweight, obesity, hypertension and IFG. Findings add strong rationale to implement targeted preventive measures in population of high risk.

Effects of Long-Term High-Fat Diet and Its Reversal on Lipids and Lipoproteins Composition in Thoracic Duct Lymph in Pigs.

BACKGROUND This study was carried out to evaluate the effects of a long-term high-fat diet on lipids and lipoproteins composition in thoracic duct lymph in pigs. MATERIAL AND METHODS We examined lymph taken from the thoracic duct from 24 female white sharp-ear pigs, divided into 3 experimental groups fed different diets for 12 months: (a) the control group, fed the standard balanced diet; (b) the HFD group, fed an unbalanced, high-fat diet, and (c) the reversal diet group (RD), fed an unbalanced, high-fat diet for 9 months and then a standard balanced diet for 3 months. RESULTS Lymph analysis after 12 months of fixed diets revealed significantly higher concentration of proteins in the HFD group in comparison to the control and RD groups. Examination of lymph lipoproteins fractions showed that the high-fat diet in the HFD group in comparison to control group caused an increase in cholesterol, phospholipids, and proteins content within HDL and chylomicrons. There were also more proteins within HDL in the HFD group in comparison to the RD group and more triglycerides within chylomicrons in the HFD group in comparison to the control group. CONCLUSIONS A long-term high-fat diet resulted in changed structure of HDL and chylomicrons in the thoracic duct lymph. Alterations in HDL composition suggest that a high-fat diet enhances reverses cholesterol transport. Changes in chylomicrons structure show the adaptation to more intense transport of dietary fat from the intestine to the liver under the influence of a high-fat diet. Reversal to a standard balanced diet had the opposite effects.

Utility of tissue Doppler imaging of systolic function to diagnose diastolic dysfunction in critically ill patients.

BACKGROUND: Diastolic dysfunction might be associated with increased mortality in severe sepsis and septic shock. In 2016 new American Society of Echocardiography (ASE)/European Association of Cardiovascular Imaging (EACVI) guidelines were published. They simplify our approach to diastolic dysfunction recognition, but they were not validated in critical care settings. The aim of the study was to assess the applicability of systolic tissue Doppler imaging of left ventricle in patients with and without diastolic dysfunction classified on the basis of the new guidelines. METHODS: Two echocardiographers analyzed transthoracic echocardiography (TTE) exa-minations and assigned patients according to ASE/EASCVI guidelines to three groups: patients with systolic dysfunction and diastolic dysfunction, patients with normal systolic function and diastolic dysfunction, and patients with normal systolic and diastolic function. RESULTS: We performed 593 examinations in 320 patients and 390 examinations in 200 patients were included in the study. In 264 examinations with ejection fraction (EF) < 55% systolic and diastolic dysfunction was diagnosed (group 1). In 114 examinations with EF ≥ 55% normal systolic and diastolic function was diagnosed (group 2). In 12 examinations with EF ≥ 55% normal systolic and abnormal diastolic dysfunction was diagnosed (group 3). After analyzing mean systolic tissue Doppler of the mitral annulus we found a statistically significant difference between group 1 and 2 (P < 0.0001) and between group 2 and 3 (P < 0.0001). The difference in values of means in group 1 vs. 3 was not statistically significant (P = 0.853). CONCLUSION: Systolic tissue Doppler analysis of mitral annulus might help to diagnose diastolic dysfunction especially in patients with preserved ejection fraction.

Does the Meeting Centres Support Programme reduce unmet care needs of community-dwelling older people with dementia? A controlled, 6-month follow-up Polish study.

INTRODUCTION: In Poland we lack a multidisciplinary and coordinated system of care for people with dementia, which would take the form of an evidence-based pathway and the number of reports on the holistic approach to caring for people living with this diagnosis is very low. AIM OF THE STUDY: The aim of the study was to investigate whether the Meeting Centres Support Programme (MCSP) is effective in meeting the needs of older people with dementia. PARTICIPANTS AND METHODS: This was done by comparing the experiences of people with dementia themselves and that of their carers at baseline and at follow-up, after 6 months of participation in MCSP or Usual Care (UC). RESULTS: The study included 47 people diagnosed with mild-to-moderate dementia (n=24, MCSP group; n=23, UC control group) and 42 informal carers (n=22, MCSP group; n=20, UC control group), all living in Wroclaw in Poland and involved in the European JPND-MEETINGDEM project. To assess cognitive functioning and severity of dementia, the Mini-Mental State Examination and Global Deterioration Scale were used. The needs were assessed using the Camberwell Assessment of Need for the Elderly. The most frequently reported unmet needs at baseline both by the persons with dementia and their carers included activities of daily living, psychological distress, and the need for company. Compared to the UC group the unmet needs were reduced considerably in the MCSP group providing convincing evidence that MCSP is effective in reducing unmet needs over a 6-month period. CONCLUSION: MCSP may be regarded as a good example of comprehensive post-diagnostic support for patients with mild-to-moderate dementia as well as their informal carers.

Clinical effectiveness of MARS treatment - multidirectional analysis of positive clinical response to treatment.

AIM OF THE STUDY: Liver failure is a life-threatening condition which often requires intensive care treatment. It is essential to quickly determine whether there are indications for extracorporeal liver support systems for the patient. The aims of the study were: to assess effectiveness of molecular adsorbent recirculating system (MARS) therapy based on selected clinical criteria, to analyze the moment of clinical response and to create a patient's profile, who will benefit clinically from the treatment. MATERIAL AND METHODS: The analysis encompassed medical histories of 65 patients treated with MARS. Effectiveness of treatment was evaluated based on selected clinical parameters. Statistical analysis was performed based on medical data gathered. RESULTS: There were 158 cycles of MARS performed, with effectiveness documented in 57 cycles (36.6%). The first MARS session was effective in 43.1% of patients. They also more often responded to the second cycle (63.6% vs. 15.4%). A significant part of the analysis was devoted to create a profile of the patient in whom positive response can be expected. A low MELD score and low baseline white blood cells (WBC) level are statistically significant factors in multivariate analysis of selected features of positive clinical response to treatment. CONCLUSIONS: MARS therapy is an effective form of treatment in a properly selected group of patients with liver failure. The first MARS session is the most effective one. It is also a good prognostic factor for further clinical response to treatment. Multifactorial analysis of positive clinical response to treatment enables to create a patient's profile based on the lower baseline MELD score and WBC.

Asymmetric and symmetric dimethylarginines and mortality in patients with hematological malignancies-A prospective study.

The study was designed to determine the associations of asymmetric (ADMA) and symmetric (SDMA) dimethylarginines plasma concentrations with all-cause mortality in patients with hematological malignancies. 33 patients with acute myeloid leukemia (AML), 31 patients with non-Hodgkin's lymphoma (nHL), 32 patients with chronic lymphocytic leukemia (CLL) and 48 patients without malignancy were enrolled into the study. Each patient was followed until death or for at least 14.5 months (range: 14.5-53). Median ADMA and SDMA were significantly elevated in AML, nHL and CLL compared to controls (ADMA: 1.36, 1.24, 1.03, 0.55 µmol/l respectively, p<0.0001; SDMA: 0.86, 0.76, 0.71, 0.52 µmol/l respectively, p<0.0001). High ADMA and SDMA were associated with increased risk for all-cause mortality in CLL group (Hazard ratio (HR) for ADMA: 3.05, 95% CI:1.58-5.88, p = 0.001; HR for SDMA: 4.71, 95% CI:1.91-11.58, p = 0.001). Our study suggests that ADMA and SDMA could be novel prognostic factors for all-cause mortality in CLL patients.

Depressive symptoms but not chronic pain have an impact on the survival of patients undergoing maintenance hemodialysis.

INTRODUCTION: More than 1/3 of patients with end-stage renal disease who are in a chronic dialysis program suffer from chronic pain and depression/anxiety. The aim of the study was to determine the impacts of symptoms of depression/anxiety, chronic pain and quality of life (QoL) on 6-year patient survival. MATERIAL AND METHODS: Observational study of end-stage renal disease patients on maintenance hemodialysis (n = 205) who met the inclusion criteria. Patients from three dialysis centers in Lower Silesia were asked to complete a battery of validated questionnaires: the Hospital Anxiety and Depression Scale (HADS), the 36-item Short Form Health Survey Questionnaire, the Verbal Rating Scale (VRS) and the Visual Analog Scale (VAS). Clinical and biochemical data (dialysis adequacy) were recorded. RESULTS: One hundred thirty from 205 enrolled hemodialysis patients (63.4%) suffered from chronic pain. Patients with pain were on maintenance dialysis for longer times and had higher levels of parathyroid hormone, more depressive symptoms and a lower QoL than those without pain. In the 6-year period, 96 (46.8%) patients died. The most common cause of death was cardiovascular disease in 44 (45.8%) patients. Highly depressed patients (HADS depression score > 8) exhibited higher mortality (< 8 vs. > 8 points; p = 0.016) independent of age, diabetes, cardiovascular disease, C-reactive protein or albumin level. CONCLUSIONS: Chronic pain, although common among hemodialysis patients, did not lower survival. Depressive symptoms are an important predictor for all-cause mortality in hemodialysis patients, with the relationship independent of nutritional or inflammatory status.
