RESUMEN
Aim: Real-world evidence on the management of hemorrhoidal disease (HD) is limited. This international study collected clinical practice data on the effectiveness of conservative treatments for acute HD on symptoms and quality of life (QoL), providing perspectives of treatment modalities from different continents. Patients & methods: The 4-week observational prospective CHORALIS study involved adult outpatients consulting for spontaneous complaints of hemorrhoids (graded using Goligher classification) and prescribed conservative treatments according to usual clinical practice. Assessments were: anal pain/discomfort (visual analog scale [VAS]), other signs/symptoms (patient questionnaire), Patient Global Impression of Change (PGI-C) questionnaire and disease-specific QoL (HEMO-FISS-QoL questionnaire). Results: Of 3592 participants, 3505 were analyzed (58.4% male; age 40.5 ± 13.7 years; history of HD in 48.4%; 72.1% Goligher grade I and II). Pain and discomfort were the most common symptoms. Most treatments were venoactive drugs (VADs; 90.9%), particularly micronized purified flavonoid fraction (MPFF; 73.7%) and diosmin (14.6%). All VAD-based therapies improved signs/symptoms (number/intensity/frequency of pain, discomfort, bleeding, swelling, itching and soiling) and QoL. MPFF was associated with a significantly greater proportion of patients with no symptoms (48.8 vs diosmin 34.4%, p < 0.001), pain disappearance (69.7 vs diosmin 52.8%, p < 0.001), treatment impact at 1 week rated on PGI-C as 'very much better' (30.5 vs diosmin 17.9%, p < 0.001) and shorter times to improvement (mean ± SD 3.9 ± 1.5 days vs diosmin 4.2 ± 1.7 days). Conclusion: In this prospective real-world study of patients with acute HD, conservative therapies consisting mainly of VADs, including MPFF, improved the clinical signs and symptoms of disease, as well as QoL. This study evidence supports clinical advantages associated with VADs, mostly MPFF, for effectively managing acute HD.
RESUMEN
Growing evidence indicates the pronounced effects of physical activity on immune functions, which may largely depend on the type of exercise, intensity, and duration. However, limited information is available regarding the effects of low-impact exercises, especially on the level of adaptive immune system. Our study aimed to investigate and compare the changes in a broad spectrum of lymphocyte subtypes after 14 weeks of aerobic-type total-body-shaping workouts (TBSW) and Pilates workouts (PW) among healthy individuals. We determined the percentages of peripheral natural killer cells and different T and B lymphocyte subtypes with flow cytometry. At the end of the exercise program, significant changes in naïve and memory lymphocyte ratios were observed in TBSW group. Percentages of naïve cytotoxic T (Tc) cells elevated, frequencies of memory Tc and T-helper cell subsets decreased, and distribution of naïve and memory B cells rearranged. Proportions of activated T cells also showed significant changes. Nonetheless, percentages of anti-inflammatory interleukin (IL)-10-producing regulatory type 1 cells and immunosuppressive CD4+CD127lo/-CD25bright T regulative cells decreased not only after TBSW but also after PW. Although weekly performed aerobic workouts may have a more pronounced impact on the adaptive immune system than low-impact exercises, both still affect immune regulation in healthy individuals.
RESUMEN
INTRODUCTION: Raynaud's disease is a vasospastic phenomenon affecting acral areas, which manifests itself in characteristic color changes. Symptoms are affected by mundane things like stress or temperature. There are also differences in the presence and progression of the disease in terms of gender, age, health-damaging behaviors (e.g., smoking) and occupation. OBJECTIVE: The aim of our study was to examine how the risk factors assumed in the literature affect the quality of life of patients with Raynaud's disease. METHOD: 110 people diagnosed with Raynaud's disease completed a questionnaire on disease-specific quality of life and risk factors. RESULTS: There was a significant difference between the groups with good and less good quality of life in terms of age (p<0.001), education (p<0.01), type of diagnosis (p<0.001), duration of illness (p<0.001), headache frequency (p<0.01), the influence of cold (p<0.05) and emotions (p<0.01). The groups currently working (p<0.01), drinking coffee more often (p<0.05), attributing less influence to emotions (p<0.001) and cold (p<0.01) had a better quality of life. According to the regression analysis, the type of diagnosis, the duration of the disease, the influencing role of emotions and cold are the most important predictors of Raynaud-specific quality of life. CONCLUSION: Our results draw attention to the role of factors that potentially affect the long-term development of the quality of life, thereby identifying the possible focuses of prevention.

Platelets are increasingly considered a bridge between mental and immunological disorders. However, data relating to platelet parameters in patients with autoimmune disorders are limited. The aim of the present study was to investigate, for the first time, the association of platelet parameters with the symptoms of affective disorders in patients with autoimmune conditions. In this cross-sectional study, we measured the complete blood count (CBC), the Generalized Anxiety Disorder Scale for anxiety (GAD-7), and the Beck Depression Inventory for depression (BDI) in 121 patients with autoimmune disorders. Mean platelet volume (MPV) was positively correlated with both anxiety and depression. Platelet distribution width (PDW) was negatively correlated with anxiety and depression. Before adjustment for covariates, logistic regression analysis revealed a significant association of MPV with depression and anxiety. After adjustment for covariates, only depression was associated with MPV. The area under the ROC curve of MPV for GAD-7 determined anxiety and BDI determined depression was 0.63. Our study showed that among the CBC hematological parameters, the MPV might be a useful biomarker of depression and anxiety in patients with autoimmune disorders. Further investigations of platelet parameters in controlled prospective studies are warranted to confirm our preliminary results.

Sarcopenia, defined as loss of muscle mass and strength, develops gradually with aging or after chronic disease. Efforts are ongoing to identify the best interventions that can slow down or stop sarcopenia. Nutrition-based interventions and exercise therapy may be beneficial; however, pharmacotherapy also could play a role. The effect of ACE inhibitors on physical performance is controversial. The present study investigates the impact of functional training on sarcopenia in the presence or absence of ACEi in elderly females. A total of 35 women over 65 years of age were selected for two groups on the basis that they were taking ACEi (n = 18) or not (n = 17). All subjects conducted a training program two times a week for 6 months. We examined various factors related to sarcopenia. After completing the short physical performance battery (SPPB) test, we found a significant improvement after 6 months of functional training. SPPB values of the ACEi group were significantly lower at the beginning of the study; however, we observed no difference between the SPPB results of the two groups after the training period. We conducted further studies to measure posture and spine mobility. Our Schober and Cobra test results revealed significantly improved spine mobility (both flexor and extensor) in both groups after 6 months of training. Furthermore, the grip strength of the hands, studied by an electric dynamometer, was significantly improved in both groups at the end of the training period. Our results indicated that functional training may improve body composition and muscle strength in patients diagnosed with sarcopenia. Furthermore, ACEi may be a helpful additional therapy in older adult patients suffering from severe sarcopenia.

Age-related changes of the immune system lead to an increased morbidity and mortality due to enhanced vulnerability to infectious diseases and malignancies. Recent studies revealed the important effects of physical activity on immune functions, which may largely depend on the type of exercise, its intensity and duration. However, limited information is available regarding the immunological effects of sport activities in older ages. The aim of our study was to examine the changes in a wide spectrum of lymphocyte subtypes after regular workout among healthy elderly individuals. We enrolled 29 elderly women with sedentary lifestyle (mean age: 67.03 ± 3.74 years) to take part in a 6-week long functional conditioning gymnastic exercise program. The percentages of peripheral natural killer (NK), NKT cells, T and B lymphocyte subtypes (early-/late-activated T, naïve and memory T, cytotoxic T (Tc), T-helper (Th)1, Th2, Th17, T regulatory type 1 (Tr1), CD4+CD127lo/-CD25bright Treg, as well as naïve and memory B cells) were determined by flow cytometry. Evaluation of the changes in functional capability of Treg cells was based on in vitro functional assays. At the end of exercise program, in parallel with improvements in body composition and physical performance, significant changes in naïve and memory lymphocyte ratios were observed. Importantly, levels of naïve Tc cells elevated, ratios of effector memory Tc cells decreased and distribution of memory B cells rearranged as well. Additionally, proportions of late-activated HLA-DR+ T cells increased, while percentages of anti-inflammatory interleukin (IL)-10 producing Tr1 cells, as well as immunosuppressive CD4+CD127lo/-CD25bright Treg cells decreased following the exercise workout. Changes observed after the regular exercise program indicate an improvement in the age-related redistribution of certain naïve and memory cell proportions and a retuned immune regulation in older ages.

OBJECTIVES: Besides cold, emotional distress is the most important trigger of Raynaud's disease (RD) attacks, although little is known about the factors that contribute to the effectiveness of coping with emotional distress. The aim of the present study was to explore alexithymia and emotion regulation and their relationship with depression and quality of life among patients with RD. METHODS: Total of 110 patients (mean age 53.65; 96 women) with RD completed self-report measures. RESULTS: Alexithymia was associated with adverse emotional regulation skills, depression, and quality of life impairment. Detailed analysis revealed that there are significant differences between alexithymic and nonalexithymic patients in emotion regulation. CONCLUSION: Alexithymia is a significant factor affecting health status in RD since it plays a significant role in emotion regulation. A multidisciplinary approach is essential to improve treatment outcome by identifying patients with high alexithymia, and to improve their emotional regulation skills.

RESUMEN
There is an absolute and relative increase in the proportion of the elderly population especially in the European countries, but this tendency can be also observed universally. By the continuous increase of the proportion of the elderly population, the medical and social related financial burdens are also increasing because of the significant decrease in health condition among older adults. The process of aging includes not only the constant decline of the general health condition and daily functioning, but also includes the decrease of the mental and cognitive performance, which further impairs the everyday life of the older adults. These findings warrant the necessity of preventive interventions in the future. According to previous findings, physical activity can be used to improve cognitive functioning and prevent further decline. In this article we provide a brief review of the literature on physical activity effects on cognition in general and with referring to three different specific forms of physical exercise; moreover, briefly discuss the important future directions of research.

Increased cardiovascular (CV) morbidity and mortality have been found in rheumatoid arthritis (RA). Tumour necrosis factor α (TNF-α) inhibitors may improve vascular function. In the first part of this study, we determined microcirculation during postoocclusive reactive hyperemia (PORH) representing endothelial function. In a nonselected population (n = 46) we measured flow-mediated vasodilation (FMD) of the brachial artery and laser Doppler flow (LDF) by ultrasound. Among LDF parameters, we determined TH1 (time to half before hyperemia), TH2 (time to half after hyperemia), Tmax (time to maximum) and total hyperemic area (AH). We measured von Willebrand antigen (vWF:Ag) by ELISA. In the second part of the study, we assessed the effects of adalimumab treatment on microcirculatory parameters in 8 early RA patients at 0, 2, 4, 8 and 12 weeks. We found significant positive correlations between FMD and LDF Tmax (R = 0.456, p = 0.002), FMD and TH2 (R = 0.435, p = 0.004), and negative correlation between vWF:Ag and Tmax (R = - 0.4, p = 0.009) and between vWF:Ag and TH2 (R = - 0.446, p = 0.003). Upon adalimumab therapy in early RA, TH2 times improved in comparison to baseline (TH2baseline = 26.9 s vs. TH24weeks = 34.7 s, p = 0,032), and this effect prolonged until the end of treatment (TH28weeks = 40.5, p = 0.026; TH212weeks = 32.1, p = 0.013). After 8 weeks of treatment, significant improvement was found in AHa (AHbaseline = 1599 Perfusion Units [PU] vs. AH8weeks = 2724 PU, p = 0.045). The PORH test carried out with LDF is a sensitive option to measure endothelial dysfunction. TH1 and TH2 may be acceptable and reproducible markers. In our pilot study, treatment with adalimumab exerted favorable effects on disease activity, endothelial dysfunction and microcirculation in early RA patients.

Changes of mean platelet volume (MPV) and platelet count (PC) could be a marker or a predictor of acute stroke (AS). We conducted a systematic review and meta-analysis of the published literature on the reporting of MPV and PC in AS. Studies were included in accordance with Patient Population or Problem, Intervention, Comparison, Outcomes, and Setting framework. The PRISMA strategy was used to report findings. Risk of bias was assessed with the Newcastle-Ottawa Scale. We included 34 eligible articles retrieved from the literature. PC was significantly lower in AS patients [standardized mean difference (SMD) = - 0.30, (95% CI: - 0.49 to - 0.11), N = 2492, P = .002] compared with controls (N = 3615). The MPV was significantly higher [SMD = 0.52 (95% CI: 0.28-0.76), N = 2739, P < .001] compared with controls (N = 3810). Subgroup analyses showed significantly lower PC in both ischemic stroke (Difference SMD = -0.18, 95% CI: -0.35-0.01) and hemorrhagic stroke (-0.94, -1.62 to -0.25), but only samples by citrate anticoagulant showed significantly lower result for patients compared to controls (-0.36, -0.68 to -0.04). Ischemic stroke patients had higher MPV (0.57, 0.31-0.83), and samples by Ethylenediaminetetraacetic acid (EDTA) anticoagulant showed significantly higher result for patients compared to controls (0.86, 0.55-1.17). PC and MPV appeared to be significantly different between patients with AS and control populations. MPV was significantly higher in ischemic stroke and PC was significantly lower in both ischemic and hemorrhagic strokes. These characteristics might be related to AS and associated with it. It is advisable to pay attention to elapsed time between phlebotomy and hematology analysis, anticoagulant and hemocytometer types in AS. SYSTEMATIC REVIEW REGISTRATION: This meta-analysis is registered on the International Prospective Register of Systematic Reviews (PROSPERO) under registration number CRD42017067864 (https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=67864).

OBJECTIVE: To compare anxiety, depression, physical health and quality of life in patients with primary Raynaud's phenomenon (PRP) and patients with secondary Raynaud's phenomenon (SRP). METHOD: Adult patients with Raynaud's phenomenon (RP) were assessed for the severity of anxiety and depressive symptoms, physical health and quality of life by using the General Anxiety Disorder Scale (GAD-7), the Beck Depression Inventory (BDI), the 12-item Short Form Health Survey: Physical Component Scale (PCS-12), and the Raynaud Specific Quality of Life Questionnaire (RQLQ), respectively. Patients with PRP and SRP were recruited for comparison at a single clinical center in Debrecen, Hungary from September to December 2017. RESULTS: In total, 60 primary and 41 secondary patients with RP were studied. Gender distribution, family status, employment status and smoking were similar in the two groups. Significantly more patients with SRP had anxiety and depressive symptoms than patients with PRP. Patients with SRP had significantly higher GAD-7 and BDI; and lower overall PCS-12 and RQLQ scores than patients with PRP. CONCLUSION: Anxiety and depression is more common in patients with SRP than in patients with PRP. Patients with SRP have a lower physical health condition and RP specific quality of life than patients with PRP. Anxiety, depression and quality of life impairments should be taken into account when managing all patients with RP. Further study is needed to assess whether appropriately designed interventions have the potential to reduce the mental and physical health burdens of RP on quality of life (QOL), especially in patients with SRP.

The purpose of this study was to evaluate the association between platelet (PLT) count and mean platelet volume (MPV) and venous thromboembolism (VTE). Thus, this study reviewed and performed a quantitative synthesis on data from the literature. This meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. 18 studies were included in this paper. A random-effect meta-analysis was conducted for the assessment of heterogeneity using thrombosis place, type of analyzer, type of anticoagulant and incubation time of samples as covariates. A mixed-effect meta-regression was performed based on the subgroup for the whole samples using thrombosis place and method of measurement as moderators for MPV and PLT, respectively. The cumulative estimates and 95% confidence interval (95%CI) of specificity, sensitivity, area under the receiver operator characteristic curve (AUC) and diagnostic odds ratio (DOR) for MPV were calculated using a random effect model. The quality assessments were evaluated according to the quality assessment and diagnostic accuracy tool-2 (QUADAS-2). The primary outcome was the occurrence of VTE. Secondary outcomes included PLT and MPV. Patient with deep vein thrombosis is likely to have a higher value of MPV than control group (P < 0.001). The presence of pulmonary embolism (PE) had no significant effect on the standardized mean difference of MPV between patients and controls. Patients are likely to have less PLT than the control group regarding all studies. However, subgroup analysis demonstrated that this effect was significant for patients with PE (P < 0.05). The summary receiver operating characteristic (SROC) curve indicated that AUC was 0.745 (95% CI: 0.672-0.834). The DOR for MPV was 4.76 (95%CI: 2.3-9.85), with diagnostic accuracy of 0.66.

Nowadays, we are witnessing a spectacular improvement in health consciousness of advanced societies. Due to the transformation of consumer behaviour, the proportion of health-conscious consumers who make well-informed and independent decisions increases steadily. In parallel, health-promoting foods are gaining more ground in the markets. Regarding the health effects, primarily cardiovascular prevention, bacterial flora modification, weight reduction as well as energy and vitamin supplementation are in focus in Hungary. Practically, any food type can be enriched with functional attributes; however, in addition to technical difficulties, the main challenge for food manufacturers is to persuade consumers to try out their products and use them continuously. In addition to research, development and innovation, consumer awareness and continuous knowledge expansion are also key factors for the success of functional foods. Consequently, strengthening the collaboration between functional food manufacturers and health professionals and researchers would be particularly beneficial, since their interrelationships might have a significant impact on the development and acceptance of novel functional foods.

INTRODUCTION: Raynaud's disease is characterized by episodic vasospastic attacks and digital ischemia usually followed by pain, numbness and cold. Despite the severity of the symptoms, the investigation of the quality of life in this disease received less attention yet. AIM: The aim of the study was to examine how the disease affects the patients' quality of life. METHOD: Semi-structured interviews were made with 28 patients diagnosed with Raynaud's disease. RESULTS: Almost every domain of quality of life is negatively affected. The somatic symptoms cause significant suffering, they are accompanied by loss of functionality; frequent preventive actions are needed; furthermore they affect job performance, commuting and sleep quality. Emotional and cognitive burdens and negative changes in interpersonal relationships were found. CONCLUSION: The findings of this study show that the disease is present as significant hardship in every aspect of daily life. Because of the decrease in the quality of life and the psychological burdens caused by this chronic disease, not only the basic medical care, but psychological treatment is also indicated.

In the present study, we investigated the effects of sour cherry seed extract (SCSE) on a variety of systemic processes that contribute to general health and viability of human subjects. The experiments were conducted according to a double-blind protocol in which six healthy individuals were administered 250-mg/day SCSE for 14 days, while four were treated with placebo. Peripheral blood was collected before and after the treatment period. Samples were analyzed for levels of selected cells, enzymes, or metabolites. Subjects that received SCSE showed increases in the values of mean cell volume, serum transferrin, mean peroxidase index, and representation of peripheral blood lymphocytes. On the other hand, decreases were observed in circulating neutrophils and ferritin levels. Changes observed in the present study do not fit into a clear pattern that might yield additional in-depth understanding of SCSE-mediated alterations in physiologic responses. The most encouraging result of the present study is the absence of any indication of toxicity by subjects consuming the extract.

Factor XIII (FXIII) is a regulator of fibrinolysis and clot firmness. Val34Leu polymorphism of its potentially active A subunit (FXIII-A) leads to faster activation of FXIII, influences clot structure and provides a moderate protection against coronary artery disease. The effect of FXIII-A Val34Leu polymorphism on the risk of atherothrombotic ischemic stroke (AIS) has been investigated in a few studies with contradictory results. In all previous studies, only patients surviving AIS were enrolled and sex-specific effects were not explored. In this retrospective multicenter cohort, we investigated the effect of FXIII-A Val34Leu polymorphism on the risk of fatal AIS in women and men. DNA isolation and genetic determinations in the case of 316 patients who died of AIS were carried out on paraffin-embedded tissue specimens. Genetic analyses for population controls, patients with history of AIS and sex-matched controls were performed on extracted genomic DNA from peripheral blood leukocytes. The prevalence of homozygous wild-type, and heterozygous genotypes, Leu34 carriers and Leu34 allele was not different significantly between the patients with fatal AIS and their respective controls. Logistic regression analysis with age as co-variant demonstrated that in women, homozygous presentation of Leu34 allele represented a more than three-fold increased risk of AIS with fatal outcome. The results demonstrate that FXIII-A Val34Leu polymorphism does not influence the occurrence of AIS, but has an effect on the severity of its outcome. This effect is sex-specific and in homozygous women, the prothrombotic/antifibrinolytic effects of FXIII-A Val34Leu polymorphism seem to prevail.

Increased environmental oxidative stress caused primarily by chemicals like polycyclic aromatic hydrocarbons, plays significant role in human diseases. A representative compound, 7,12-dimethylbenz(a)anthracene (DMBA), was used for modeling oxidative damages including the significant decrease of the antioxidant capacity of the blood. Selenium has antioxidant effects but with a narrow therapeutic window. In our current studies to avoid accidental overdose and toxicity selenium was given to meat-producing animals. The standard rodent diet of mice was replaced by meat from lambs either on standard or selenium-enriched diet. Selenium concentration of lamb meat was enhanced three times by nano-selenium administration and an increase in the antioxidant capacity of the blood of mice was measured after the indirect selenium supplementation. Protective effects were also observed against DMBA-induced immunotoxicity. Twice the amount of white blood cells and among them three times more phagocytes survived. Similarly, in their renewal system in bone marrow twice the amount of cells survived and regenerative capacity of granulopoiesis was four times higher than in control DMBA-damaged mice. Our findings suggest functional dietary benefits of lamb meat enriched with selenium by feeding lambs with nanoparticle selenium supplements.

INTRODUCTION: We studied the effect of rosuvastatin on endothelial and macrovascular function, cardiovascular risk factors and the complement pathway in patients with systemic sclerosis (SSc). METHODS: Altogether 28 patients with SSc underwent laboratory and complex vascular assessments before and after six months of 20 mg rosuvastatin treatment. Flow-mediated dilation (FMD) of the brachial artery, as well as carotid artery intima-media thickness (ccIMT), carotid-femoral and aorto-femoral pulse wave-velocity (PWV) were analyzed by ECG-synchronized ultrasound. Ankle-brachial index (ABI) was determined by Doppler, and forearm skin microcirculation was assessed by Laser Doppler perfusion monitoring. RESULTS: Brachial artery FMD significantly improved upon rosuvastatin therapy (2.2% ± 3.3% before versus 5.7% ± 3.9% after treatment, P = 0.0002). With regard to patient subsets, FMD significantly improved in the 21 lcSSc patients (from 2.1% to 5.6%, P = 0.001). In the seven dcSSc patients, we observed a tendency of improvement in FMD (from 3% to 6%, P = 0.25). Changes in PWV, ccIMT and ABI were not significant. Mean triglyceride (1.7 ± 0.97 versus 1.3 ± 0.46 mmol/l, P = 0.0004), total cholesterol (5.3 ± 1.6 mmol/l versus 4.2 ± 1.3 mmol/l, P = 0.0003), low density lipoprotein cholesterol (3.0 ± 1.3 versus 2.2 ± 1.0 mmol/l, P = 0.005) and C-reactive protein levels (CRP) (5.1 ± 5.2 versus 3.4 ± 2.7, P = 0.01) levels significantly decreased after rosuvastatin treatment. Mean C3, C4 and IC levels also decreased significantly as compared to pretreatment values. CONCLUSIONS: Six-month rosuvastatin therapy improves endothelial function and lowers CRP, C3, C4 and IC levels indicating possible favourable effects of this statin on the cardiovascular and immune system in SSc.
