RESUMO
Chronic kidney disease is classified as a civilization disease and is being diagnosed in an increasing number of patients. Hypertension and diabetes mellitus often coexist in hemodialyzed patients. The aim of the present study was to identify publications on the oral cavity status of multimorbid hemodialyzed adult patients additionally diagnosed with hypertension and/or diabetes mellitus, published between 2012 and 2022 to establish evidence of the impact of hypertension and diabetes mellitus on the oral status of hemodialyzed patients. Scopus and Web of Science databases were searched. Eight articles were included in the review. In total, 3 articles discussed oral hygiene in hemodialyzed patients, 4 discussed periodontal status, 3 discussed mucosa condition and saliva parameters, and 3 discussed the problem of Candidiasis infections. The conclusions were as follows: there is still a limited number of publications discussing the oral status of hemodialyzed patients diagnosed with hypertension; involved articles have proven that coexisting diseases can influence the oral cavity status of hemodialyzed patients and cause periodontal disorders, lower hygiene status, saliva parameters and make the risk of Candida infections higher.

Dynamic development of medicine in the 20th and 21st centuries has only been possible due to its split into narrow specialties. The increasingly complicated and costly technologies used in clinical practice can only be mastered by small groups of highly qualified specialists; however, diagnosis and treatment are not about matching a patient with the latest and most sophisticated technologies but about finding an optimal patient oriented solution, as it is the human being as a whole that needs help. To achieve this goal, a close collaboration of different specialists is required, but the key role rests with a physician with good general internal medicine skills and the right motivation to act. Management of patients presenting to internal medicine departments requires not only the skill of appropriate pathophysiological reasoning based on extensive knowledge and acquired experience, but many times also the civil courage of the physician. The task is further complicated by chronic underfunding of these wards. The aim of the present review is to reflect on the current state and prospects of Polish internal medicine as well as to attempt a definition of an internist and their role in the integration of different medical specialties. It also stresses the importance of a master in the teaching and practice of medicine and presents profiles of 4 eminent Polish internists.

BACKGROUND: Amantadine has been proposed as a treatment for COVID-19 because it shows anti-SARS-CoV-2 activity in vitro. However, to date, no controlled study has assessed the safety and efficacy of amantadine in COVID-19. RESEARCH QUESTION: Whether amantadine is effective and safe among patients with different COVID-19 severity classifications. STUDY DESIGN: and Methods: This was multi-centre, randomised, placebo-controlled study.Patients with oxygen saturation ≤94% and no need for high-flow oxygen or ventilatory support were randomly allocated to receive oral amantadine or placebo (1:1) for 10 days in addition to standard care. The primary endpoint was time to recovery assessed over 28 days since randomisation, defined as discharge from hospital or no need for supplemental oxygen. RESULTS: The study was terminated early due to a lack of efficacy after an interim analysis. Final data from 95 patients who received amantadine (mean age, 60.2 years; 65% male; 66% with comorbidities) and 91 patients who received placebo (mean age, 55.8 years; 60% male; 68% with comorbidities) were obtained. The median (95% CI) time to recovery was 10 days both in the amantadine (9-11) and placebo arms (8-11; subhazard ratio = 0.94 [95%CI 0.7-1.3]). The percentage of deaths and percentage of patients who required intensive care at 14 and 28 days did not significantly differ between the amantadine and placebo groups. INTERPRETATION: Adding amantadine to standard care in patients hospitalised with COVID-19 did not increase the likelihood of recovery.

Background: Societal aging - as a global demographic phenomenon - shows no indication of abating. As a result, the problem of age-associated disability and related long-term care is emerging as a major public health challenge. It is important that methods for identifying older adults at risk of adverse outcomes are implemented early. Methods: The study group consisted of 145 individuals, 44.1% women, who were randomized from community-dwelling 60-74-year-old adults. A comprehensive geriatric assessment was supplemented with Fried frailty phenotype evaluation and blood tests (including adhesion molecules, matrix metalloproteinases and neurotrophic factors). A follow-up by phone call was made for at least 3 years after the initial examination. Composite endpoint (CE) included falls, hospitalization, institutionalization and death. Results: Mean study group age was 66.5 ± 4.1 years () and mean number of diseases was 3.7 ± 2.2. Functional status of the subjects was good, as indicated by high Barthel Index scores of 99.1 ± 2.4, MMSE scores of 29.0 ±1.5 and no frailty case. During a three-year follow-up, 71 participants (49.0%) experienced any CE-events. The Wilcoxon-Gehan test indicates that a higher probability of three-year CE completion was associated with an age >65 years (P = 0.006), coronary artery disease (CAD) (P = 0.008), 6-Minute Walk Test <432 m (P = 0.034), serum glucose >120 mg/dL (P = 0.047), serum cortisol >10 µg/dL (P = 0.011), leptin ≥15 ng/mL (P = 0.018), P-selectin ≥23 ng/mL (P = 0.006) and GDNF ≥20 pg/mL (P = 0.004). CAD (OR = 3.64, 95% CI = 1.53-8.69, P = 0.004), educational status (OR = 0.87, 95% CI = 0.77-0.98, P = 0.022) and P-selectin levels (OR = 1.07, 95% CI = 1.02-1.13, P = 0.013) were independent measures predicting three-year CE occurrence in multivariate logistic regression analysis adjusted for clinical and functional measures, and blood tests. Conclusion: Coronary artery disease, poorer lower educational status and higher P-selectin levels were predictive of adverse outcomes in the community-dwelling healthy-aging early-old adults during three-year follow-up.

Metabolic syndrome (MS) and anxiety disorders are common problems among hemodialysis patients (HD). However, there have been no studies defining the role of physical activity in reducing anxiety in HD patients with MS. This study was aimed to determine the effects on the severity of anxiety of a four-week rehabilitation program for HD patients, with or without metabolic syndrome (MS), planned and adapted to their abilities. The study was single-center, interventional, non-randomized, and prospective. Fifty-eight individuals completed the project (28 HD patients and 30 controls (C) with normal kidney function). Each group was divided into two subgroups with respect to MS. The mean age of the subjects in the HD and C groups was 56.9 ± 13.3 years (x¯ ± SD) and 61.5 ± 8.3 years (x¯ ± SD), respectively. Planned and adapted to the patient's abilities, the rehabilitation program based on physiotherapy was provided to each subject for 4 weeks. Baseline and post-intervention determined anxiety levels using the State-Trait Anxiety Inventory (STAI). The X1 scale tests state anxiety, and the X2 scale tests trait anxiety. Post-intervention, there was no significant difference in the intensity of state anxiety observed in HD patients compared to C with normal renal function, as observed before the program. After four weeks of regular physical activity planned and adapted to the patient's abilities in an inpatient ward, the level of state anxiety (X1) and trait anxiety (X2) lowered considerably in all HD patients (respectively: 35.1 ± 8.0 vs. 29.2 ± 5.0, p = 0.001 for X1 and 41.8 ± 9.1 vs. 38.1 ± 5.9, p = 0.008 for X2). The rehabilitation program significantly reduced the intensity of state anxiety (X1) in HD patients with MS (35.8 ± 7.9 vs. 29.2 ± 5.1; p = 0.01). The rehabilitation program helped to significantly reduce the intensity of trait anxiety (X2) in HD patients without MS (41.9 ± 10.7 vs. 36.9 ± 5.9; p = 0.04). Four-week physical activity planned and adapted to the patient's abilities reduces the intensity of anxiety in HD patients and controls with normal renal function. HD patients with MS benefit more in terms of reducing perceived state anxiety, and HD patients without MS in terms of reducing trait anxiety.

BACKGROUND: Kidney dysfunction is a common complication in patients with severe liver cirrhosis. There is a need for discovery and validation of novel biomarkers for earlier AKI detection. The aim of this study was to determine if tubular injury markers: NGAL and KIM-1 could be helpful in the early diagnosis of AKI in patients undergoing therapeutic paracentesis. METHODS: This preliminary study included 24 adult patients diagnosed with liver cirrhosis who had been hospitalized due to massive ascites requiring paracentesis. Pre- and post-paracentesis plasma samples were taken from each patient and biomarkers were measured. RESULTS: Before paracentesis, the levels of serum and urinary NGAL were similar between patients and controls; while urinary KIM-1 was markedly increased in liver cirrhotic patients (0.76 vs. 0.24 ng/ml; respectively). Although urinary NGAL levels in AKI patients were 5-time greater than in non-AKI subgroup, the difference did not reach statistical significance (13.2 vs 1.5 pg/mL, p = 0.06). Serum NGAL level, post-procedure, was 3 times greater in AKI subgroup. CONCLUSION: Kidney injury markers, especially serum NGAL, may be useful for the early detection of AKI. However, further research is required to determine if biomarkers of kidney injury may help identify patients with cirrhosis who would most likely benefit from early AKI prevention and treatment.

BACKGROUND: Simple, easy-to-perform, safe and cost-effective methods for the prediction of adverse outcomes in older adults are essential for the identification of patients who are most likely to benefit from early preventive interventions. METHODS: The study included 160 community-dwelling individuals aged 60-74 years, with 44.4% women. A comprehensive geriatric assessment was performed in all participants. Bioimpedance body composition analysis included 149 subjects. Among other tests, functional assessment included the Barthel Index of Activities of Daily Living (Barthel Index), Mini-Mental State Examination (MMSE), Timed Up and Go (TUG) and Fried frailty phenotype. Follow-up by telephone was made after at least 365 days. The composite endpoint (CE) included fall, hospitalization, institutionalization and death. RESULTS: Cohort characteristics: age 66.8±4.2 years (mean±SD), 3.81±2.23 diseases, 4.29±3.60 medications or supplements, and good functional status (MMSE 29.0±1.5, Barthel Index 98.1±8.2, prevalence of Fried frailty phenotype 2.5%). During one-year follow-up, 34 subjects (21.3%; 95% confidence interval [CI] =14.9-27.6%) experienced CE: hospitalizations (13.8%; 95% CI=8.41-19.1), falls (9.38%; 95% CI=4.86-13.9), death (0.63%; 95% CI=0-1.85) and no institutionalization. A higher probability of CE was associated with age ≥70 years (P=0.018), taking any medication or supplements (P=0.007), usual pace gait speed ≤0.8 m/s (P=0.028) and TUG >9 s (P<0.002). TUG was the only independent measure predicting one-year CE occurrence (OR=1.22, 95% CI=1.07-1.40, P=0.003) in multivariate logistic regression. However, its predictive power was poor; the area under the receiver operating characteristic curve was 0.659 (95% CI 0.551-0.766, P=0.004) and Youden's J statistic for a TUG cut-off of 9.0 s was 0.261 (sensitivity 0.618 and specificity 0.643). CONCLUSION: The TUG test was superior to frailty phenotype measures in predicting one-year incidence of a CE consisting of fall, hospitalization, institutionalization and death in a cohort of healthy-aging community-dwelling early-old adults, although its value as a stand-alone test was limited.

BACKGROUND: Demographic aging results in increased incidence of old-age disability. Frailty is a major factor contributing to old-age disability. The aim of this study was to investigate the prevalence of the frailty phenotype as defined by Fried et al and to estimate the need for associated preventative interventions in early-old community-dwelling inhabitants of the southern industrial region of Poland, as well as to investigate the defining components of the frailty phenotype. METHODS: The study group consisted of 160 individuals with an average age of 66.8 ± 4.2 years ( ± SD), 71 (44.4%) of study participants were women. The cohort was randomized out of over 843 thousand community-dwelling Upper Silesian inhabitants aged 60-74 years, who agreed to participate in this project. A comprehensive geriatric assessment (CGA), frailty phenotype test (as described by Fried et al) blood tests and bioimpedance body structure analysis was completed for study participants. Functional assessment included Barthel Index of Activities of Daily Living (Barthel Index), Instrumental Activities of Daily Living Scale (IADL), Mini-Mental State Examination (MMSE), the Timed Up and Go (TUG) test, Tinetti Performance-Oriented Mobility Assessment (POMA), and Geriatric Depression Scale - Short Form (GDS-SF). RESULTS: Prefrailty was diagnosed in 24.4% of the subjects (95% Confidence Interval (CI) = 17.7-31.0%; 31% in women and 19.1% in men, P=0.082) and frailty in 2.5% subjects (95% CI 0.1-4.9%; more frequently in women: 4.2% versus 1.1% in men, P=0.046). Having one or more positive frailty criteria was positively associated with depression (odds ratio (OR)=2.85, 95% CI=1.08-7.54, P=0.035) and negatively associated with MMSE score (OR=0.72, 95% CI=0.56-0.93, P=0.012) and fat-free mass (OR=0.96, 95% CI=0.92-0.99, P=0.016) in multivariate logistic regression analysis adjusted for age, sex, disease prevalence, number of medications, functional tests (Barthel Index, IADL, MMSE, GDS-SF), BMI, bioimpedance body composition score, and blood tests. CONCLUSION: At least 25% of the early-old community-dwelling population would benefit from a frailty prevention program. The frailty phenotype reflects both physical and mental health in this population.

RATIONALE & OBJECTIVE: Clinical practice guidelines for dietary intake in hemodialysis focus on individual nutrients. Little is known about associations of dietary patterns with survival. We evaluated the associations of dietary patterns with cardiovascular and all-cause mortality among adults treated by hemodialysis. STUDY DESIGN: Prospective cohort study. SETTING & PARTICIPANTS: 8,110 of 9,757 consecutive adults on hemodialysis (January 2014 to June 2017) treated in a multinational private dialysis network and with analyzable dietary data. EXPOSURES: Data-driven dietary patterns based on the GA2LEN food frequency questionnaire. Participants received a score for each identified pattern, with higher scores indicating closer resemblance of their diet to the identified pattern. Quartiles of standardized pattern scores were used as primary exposures. OUTCOMES: Cardiovascular and all-cause mortality. ANALYTICAL APPROACH: Principal components analysis with varimax rotation to identify common dietary patterns. Adjusted proportional hazards regression analyses with country as a random effect to estimate the associations between dietary pattern scores and mortality. Associations were expressed as adjusted HRs with 95% CIs, using the lowest quartile score as reference. RESULTS: During a median follow-up of 2.7 years (18,666 person-years), there were 2,087 deaths (958 cardiovascular). 2 dietary patterns, "fruit and vegetable" and "Western," were identified. For the fruit and vegetable dietary pattern score, adjusted HRs, in ascending quartiles, were 0.94 (95% CI, 0.76-1.15), 0.83 (95% CI, 0.66-1.06), and 0.91 (95% CI, 0.69-1.21) for cardiovascular mortality and 0.95 (95% CI, 0.83-1.09), 0.84 (95% CI, 0.71-0.99), and 0.87 (95% CI, 0.72-1.05) for all-cause mortality. For the Western dietary pattern score, the corresponding estimates were 1.10 (95% CI, 0.90-1.35), 1.11 (95% CI, 0.87-1.41), and 1.09 (95% CI, 0.80-1.49) for cardiovascular mortality and 1.01 (95% CI, 0.88-1.16), 1.00 (95% CI, 0.85-1.18), and 1.14 (95% CI, 0.93-1.41) for all-cause mortality. LIMITATIONS: Self-reported food frequency questionnaire, data-driven approach. CONCLUSIONS: These findings did not confirm an association between mortality among patients receiving long-term hemodialysis and the extent to which dietary patterns were either high in fruit and vegetables or consistent with a Western diet.

INTRODUCTION: Zonulin is a protein that reversibly modulates the permeability of tight junction of the small intestine wall. As the serum concentration of "zonulin family peptides" (ZFPs) is considered to be a sensitive and useful marker of intestinal wall permeability, its serum level may affect the volume of ascites fluid and change in gut microbiota. The aim of the study was to assess the association between concentrations of ZFPs in serum and ascites in relation to the severity of liver cirrhosis. METHODS: The preliminary study included 24 adult patients diagnosed with alcoholic or viral liver cirrhosis. 18 healthy adult subjects were enrolled as the control group. In patients and controls, there were measured serum and ascites (only in patients) ZFPs, serum bilirubin, creatinine, alanine aminotransferase, total protein, and C-reactive protein (CRP). RESULTS: Cirrhotic patients had lower serum hemoglobin (11.6 vs. 14.3 mg/dL; p < 0.001), platelet count (178 vs. 305 × 103/mm3; p < 0.01), total protein and albumin (58.6 vs. 74.3 g/dL; p < 0.001, 26.6 vs. 42.3 g/dL; p < 0.001, respectively), and serum ZFPs (30.5 vs. 62.0 ng/mL; p < 0.001) in comparison to controls. In patients with cirrhosis serum bilirubin, C-reactive protein level and INR were higher than in controls (3.07 vs. 0.96 mg/dL; 36.9 vs. 5 mg/L; 1.53 vs. 0.95; p < 0.001, respectively). Patients with low ZFP levels were characterized with lower ascites ZFP levels (0.25 vs. 16.4 ng/mL; p < 0.001) and ascites/serum index (0.011 vs. 0.462; p < 0.001). There were negative correlations between ascites ZFPs and platelet count (R = -0.497; p < 0.01) and positive correlation with INR (R = 0.640; p < 0.001). ZFP index positively correlated with platelet count (R = 0.726; p < 0.001) and negatively with INR (R = -0.392; p = 0.06). CONCLUSIONS: Decrease serum ZFP levels seem to reflect their decreased liver synthesis but not increased gut permeability in patients with liver cirrhosis. The physiologically low level of ZFPs in transudate is increased in exudate.

BACKGROUND AND OBJECTIVES: Higher fruit and vegetable intake is associated with lower cardiovascular and all-cause mortality in the general population. It is unclear whether this association occurs in patients on hemodialysis, in whom high fruit and vegetable intake is generally discouraged because of a potential risk of hyperkalemia. We aimed to evaluate the association between fruit and vegetable intake and mortality in hemodialysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Fruit and vegetable intake was ascertained by the Global Allergy and Asthma European Network food frequency questionnaire within the Dietary Intake, Death and Hospitalization in Adults with ESKD Treated with Hemodialysis study, a multinational cohort study of 9757 adults on hemodialysis, of whom 8078 (83%) had analyzable dietary data. Adjusted Cox regression analyses clustered by country were conducted to evaluate the association between tertiles of fruit and vegetable intake with all-cause, cardiovascular, and noncardiovascular mortality. Estimates were calculated as hazard ratios with 95% confidence intervals (95% CIs). RESULTS: During a median follow up of 2.7 years (18,586 person-years), there were 2082 deaths (954 cardiovascular). The median (interquartile range) number of servings of fruit and vegetables was 8 (4-14) per week; only 4% of the study population consumed at least four servings per day as recommended in the general population. Compared with the lowest tertile of servings per week (0-5.5, median 2), the adjusted hazard ratios for the middle (5.6-10, median 8) and highest (>10, median 17) tertiles were 0.90 (95% CI, 0.81 to 1.00) and 0.80 (95% CI, 0.71 to 0.91) for all-cause mortality, 0.88 (95% CI, 0.76 to 1.02) and 0.77 (95% CI, 0.66 to 0.91) for noncardiovascular mortality and 0.95 (95% CI, 0.81 to 1.11) and 0.84 (95% CI, 0.70 to 1.00) for cardiovascular mortality, respectively. CONCLUSIONS: Fruit and vegetable intake in the hemodialysis population is low and a higher consumption is associated with lower all-cause and noncardiovascular death.

BACKGROUND: Chronic kidney disease is a risk factor for oral diseases, which may be associated with premature death. We evaluated the risk of all-cause and cardiovascular mortality associated with oral mucosal lesions in adults with kidney failure treated with long-term haemodialysis. METHODS: Oral mucosal lesions (herpes, ulceration, neoformation, white lesion, red lesion, oral candidiasis, geographical tongue, petechial lesions, and fissured tongue) were evaluated within the Oral Diseases in Haemodialysis (ORAL-D) study, a multinational cohort study of 4726 haemodialysis adults. We conducted cox regression analyses adjusted for demographic and clinical variables to evaluate the association with all-cause and cardiovascular mortality. RESULTS: Overall, 4205 adults (mean age 61.6 ± 15.6 years) underwent oral mucosal examination with 40% affected by at least one lesion. The prevalence of oral lesions was (in order of frequency): oral herpes 0.5%, mucosal ulceration 1.7%, neoformation 2.0%, white lesion 3.5%, red lesion 4.0%, oral candidiasis 4.6%, geographical tongue 4.9%, petechial lesions 7.9%, and fissured tongue 10.7%. During median follow-up of 3.5 years, 2114 patients died (1013 due to cardiovascular disease). No association was observed between any individual oral lesion and all-cause or cardiovascular mortality when adjusted for comorbidities, except for oral candidiasis, which was associated with all-cause mortality (adjusted hazard ratio 1.37, 95% CI 1.00 to 1.86) and cardiovascular mortality (adjusted hazard ratio 1.64, 95% CI 1.09 to 2.46). CONCLUSION: Oral mucosal lesions are prevalent in haemodialysis patients. Oral candidiasis appears to be a risk factor for death due to cardiovascular diseases.

Hemodialysis patients perform little physical activity. We formulated a hypothesis that some factors, i.e., frailty, medical and functional factors, psychological factors, quality of life, awareness of recommendations, and sociodemographic factors influence the decisions of taking up physical activity. This prospective study comprised 72 dialysis patients aged 57.8 ± 16.0 ( x ¯ ± SD; in the range of 19-87 years of age). The following research tools were used: an interview about awareness of the physical activity recommendations, the Canadian Study of Health and Aging Scale (CSHA-CFS), scales for the assessment of functional status, State-Trait Anxiety Inventory (STAI), Acceptance of Illness Scale (AIS), and the questionnaire of Kidney Disease Quality of Life (KDQOL-SF 1.3). The majority of patients diagnosed with frailty did not follow the physical activity recommendations (79.3%). Quality of life was better in active patients compared to inactive patients, especially in the domains of sleep and physical performance. The severity of trait anxiety was significantly higher in patients who did not follow the recommendations compared to patients who adhered to physical activity recommendations (46.0 ± 10.5 vs. 40.0 ± 8.2; p = 0.021 ). The likelihood of adherence decreased by 1% after each subsequent month of dialysis (odds ratio = 0.99; 95% confidence interval = 0.972-0.999; p = 0.047 ). Adherence was most limited by frailty. Adherence to recommendations on physical activity was affected by: motivation, lower levels of trait anxiety, and better quality of life. Age modified the effect of awareness and acceptance of the disease on adherence to physical activity recommendations.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is among the most common causes of liver disease worldwide. There is growing evidence on pathogenesis and pathophysiology of NAFLD. However, there is still no universally accepted pharmacotherapy protocol. METHODS: The study was conducted on 42 patients with NAFLD. They were randomized to dietary treatment alone (n = 21) or to diet and metformin therapy (n = 21). Liver ultrasonography, controlled attenuation parameter (CAP), liver stiffness (LS), complete blood count, anthropometric and biochemical parameters were obtained before treatment (baseline), and after 3 and 5 months of the therapy. RESULTS: Patients treated with diet and metformin exhibited significantly decreased CAP values at 3 and 5 months of the therapy compared to baseline (319 dB/m vs. 285 dB/m; p < 0.05; 319 dB/m vs. 295 dB/m; p < 0.05 respectively). Five months of diet and the metformin therapy resulted in significant reduction of LS value (6.2 kPa vs. 5.2 kPa; p < 0.05), while patients treated with diet alone had no significant changes in liver CAP and LS measurements. CONCLUSIONS: Metformin therapy combined with dietary treatment seems to be effective for the reduction of hepatic steatosis and fibrosis. However, considering limitations of the study and inconsistent results of previous investigations in this area, there is a need for further research on metformin efficacy in this group of patients.

Muscle activity during a hemodialysis procedure improves its efficacy. We have formulated a hypothesis that vibrations generated by a specially-designed dialysis chair can, the same as physical exercise, affect the filtering of various fluids between fluid spaces during the hemodialysis procedure. This prospective and interventional study included 21 dialyzed patients. During a single dialysis session, each patient used a prototype device with the working name "vibrating chair". The chair's drive used a low-power cage induction motor, which, along with the worm gear motor, was a part of the low-frequency (3.14 Hz) vibration-generating assembly with an amplitude of 4 mm. Tests and measurements were performed before and after the vibration dialysis. After a single hemodialysis session including five 3-min cycles of vibrations, an increase in K t / V in relation to non-vibration K t / V ( 1.53 ± 0.26 vs. 1.62 ± 0.23 ) was seen. Urea reduction ratio increased significantly ( 0.73 ± 0.03 vs. 0.75 ± 0.03 ). A significant increase in systolic blood pressure was observed between the first and the third measurement ( 146 ± 18 vs. 156 ± 24 ). The use of a chair generating low-frequency vibrations increased dialysis adequacy; furthermore, it seems an acceptable and safe alternative to intradialytic exercise.

BACKGROUND: Elevated circulating osteoprotegerin (OPG) level is associated with an increased risk of hospitalization for ischemic stroke and coronary artery disease. The aim of the present study was to analyze whether OPG assessment may improve the prediction of mortality in patients with stroke. PATIENTS AND METHODS: Serum OPG, fetuin A, 25-OH-D3, intact parathyroid hormone levels were assessed in serum samples which were left over after routine tests in a hospital laboratory. This assessment was conducted in 240 consecutive patients with acute ischemic stroke, admitted within 24hours after the onset of symptoms to the Stroke Unit. Mortality data were obtained from the local registry office. RESULTS: The mean OPG serum level was 14.6 ± 6.0pmol/L (range: 3.7-43.4). There were no significant differences in the OPG values between men and women (13.9 ± 5.0 versus 15.1 ± 6.7 pmol/L; P = .12). Therefore, tertiles were calculated for the whole group. During the follow-up, 85 (35.4%) patients died and 92 (38.3%) died or had recurrent stroke. OPG level appeared a significant predictors of death and composite end-point (death/recurrent stroke), in addition to the well-established once (age, atrial fibrillation, diabetes RANKIN at admission and discharge, severity of stroke). In multivariable stepwise backward analyses, the OPG level persisted as a significant and independent predictor of death (hazard ratio [HR]â¯=â¯1.084 (95% confidence intervals: 1.036-1.134)] and composite and point (HRâ¯=â¯1.082 [1.037-1.129]). CONCLUSIONS: OPG level may be considered as a predictor of mortality in stroke patients.

BACKGROUND: Resistin (RES) concentration increases in end-stage renal disease patients. However, there have been no studies defining the role of physical activity in RES concentrations in hemodialyzed (HD) patients. This study was aimed to determine metabolic and inflammatory effects, including RES, of 4-week supervised rehabilitation program in HD patients, with or without metabolic syndrome (MS). METHODS: The study was completed by 28 patients aged 56.9±13.3 years ( x ¯ ± SD ) who were HD for 50.6±73.4 months, and 30 controls aged 61.5±8.3 years with normal renal function. Both the groups were divided into two subgroups with respect to MS. Individualized supervised rehabilitation program based on physiotherapy, including exercises, was provided to each subject for 4 weeks. Baseline and post-intervention complete blood count, glycated hemoglobin (HbA1c) and levels of serum RES, leptin, adiponectin, cystatin C, erythropoietin, high sensitivity C-reactive protein (hs-CRP), tumor necrosis factor alpha (TNF-α), interleukin-6, transforming growth factor- ß1, plasminogen activator inhibitor-1 homocysteine, insulin, albumin, parathyroid hormone (PTH), and phosphorus were measured. RESULTS: Compared to controls, HD patients showed higher baseline leucocytes count and higher serum concentrations of RES, leptin, cystatin C, hs-CRP, TNF-α, homocysteine, phosphorus, PTH while hemoglobin, glucose, and albumin concentrations. A positive correlation between serum albumin and RES concentrations was observed in HD patients. Post-intervention RES increase was observed in HD patients without MS (post-intervention 34.22±8.89 vs baseline 30.16±11.04 ng/mL; P=0.046) while no change was observed in patients with MS and in the control group. CONCLUSION: MS modifies a RES response to the rehabilitation program in HD patients.
