Serum fetuin-A is decreased in cirrhotic patients with Wilson's disease.

INTRODUCTION: Wilson's disease may lead to cirrhosis, but timely medical treatment could slow down its progression. Clinical markers helping early diagnosis are essential. Decreased fetuin-A concentration has been reported in cirrhosis of different etiologies. The aim of this study was to investigate whether decreased serum fetuin-A concentration could identify patients with Wilson's disease who developed cirrhosis. MATERIALS AND METHODS: In this cross-sectional study we determined the serum fetuin-A concentration of 50 patients with Wilson's disease. We analyzed the data of patients with liver involvement, comparing cirrhotic and non-cirrhotic patients. RESULTS: Among patients with liver involvement those with cirrhosis had significantly lower fetuin-A and albumin level, white blood cell and platelet count. Fetuin-A negatively correlated with disease duration, bilirubin level, positively with total protein and albumin concentration, but not with copper and ceruloplasmin concentrations or markers of systemic inflammation. In multivariate analysis with fetuin-A and the Nazer score or its parameters only fetuin-A was a significant determinant of having cirrhosis. In receiver operator curve analysis among patients with liver involvement the fetuin-A level of 523 µg/ml was associated with cirrhosis with 82% sensitivity and 87% specificity. The presence of the H1069Q mutation was not associated with alteration in fetuin-A concentration. CONCLUSIONS: The serum concentration of fetuin-A is a sensitive marker of liver cirrhosis in Wilson's disease, independently of the H1069Q mutation, ceruloplasmin concentration or systemic inflammation.

[The association between diabetes complications and symptoms of depression and anxiety]. / A cukorbetegség szövodményeinek összefüggése a depressziós és szorongásos tünetekkel.

INTRODUCTION: The bidirectional relationship between diabetes and depression results in severe disease burden. Co-occurring depression is associated with a higher rate of diabetes complications. These complications impair quality of life, however, their impact on depressive symptoms is controversial. OBJECTIVE: In our cross-sectional study, we aimed to investigate whether the presence of diabetes complications is associated with depressive and anxiety symptoms among patients with type 2 diabetes in general practice. METHOD: We obtained patient history, anthropometric, socioeconomic, laboratory parameters. For symptom assessment, the Beck Depression Inventory (BDI) and the Hamilton Anxiety Scale (HAM-A) were used. We collected data between September 2018 and February 2020. RESULTS: We included 338 consecutive patients with type 2 diabetes. The mean age of the sample was 63.98 ± 11.51 (years ± SD), 61.2% of participants were female. We found significant univariate association between diabetes complications and older age, less physical activity, higher body mass index, insulin therapy, higher HbA1c, higher creatinine and carbamide concentrations, worse depressive and anxiety symptoms. In multivariate analysis, diabetes complications and certain socio-demographic factors (female gender, lower education, rural-dwelling) were the determinants of higher BDI and HAM-A scores. CONCLUSION: Among primary care patients with type 2 diabetes, the prevalence of depressive and anxiety symptoms was higher and more severe in patients with diabetes complications. The recommended screening for affective disorders among patients with diabetes is especially justified if complications are present. Orv Hetil. 2023; 164(3): 79-87.

What factors empower general practitioners for early cancer diagnosis? A 20-country European Delphi Study.

BACKGROUND: Some symptoms are recognised as red flags for cancer, causing the General Practitioner (GP) to refer the patient for investigation without delay. However, many early symptoms of cancer are vague and unspecific, and in these cases, a delay in referral risks a diagnosis of cancer that is too late. Empowering GPs in their management of patients that may have cancer is likely to lead to more timely cancer diagnoses. AIM: To identify the factors that affect European GPs' empowerment in making an early diagnosis of cancer. METHODS: This was a Delphi study involving GPs in 20 European countries. We presented GPs with 52 statements representing factors that could empower GPs to increase the number of early cancer diagnoses. Over three Delphi rounds, we asked GPs to indicate the clinical relevance of each statement on a Likert scale.The final list of statements indicated those that were considered by consensus to be the most relevant. RESULTS: In total, 53 GPs from 20 European countries completed the Delphi process, out of the 68 GPs who completed round one. Twelve statements satisfied the pre-defined criteria for relevance. Five of the statements related to screening and four to the primary/secondary care interface. The other selected statements concerned information technology (IT) and GPs' working conditions. Statements relating to training, skills and working efficiency were not considered priority areas. CONCLUSION: GPs consider that system factors relating to screening, the primary-secondary care interface, IT and their working conditions are key to enhancing their empowerment in patients that could have cancer. These findings provide the basis for seeking actions and policies that will support GPs in their efforts to achieve timely cancer diagnosis.

Severity of depressive but not anxiety symptoms impacts glucose metabolism among patients with type 2 diabetes in primary care.

Background: Data from primary care regarding the prevalence of symptoms of depression and anxiety, and their effect on glycemic control among people with diabetes is lacking in Hungary. The recently introduced Patient Health Record (PHR) requires family doctors to screen for depressive symptoms. Objectives: We aimed to investigate the prevalence of depressive and anxiety symptoms among patients with type 2 diabetes in the general practice, and the relationship between these affective disorders and glycated hemoglobin (HbA1c) level. Methods: We included 338 consecutive patients with type 2 diabetes from six primary care practices in this cross-sectional study. A self-administered questionnaire (patient history, anthropometric, socioeconomic, laboratory parameters), the Beck Depression Inventory (BDI) and the Hamilton Anxiety Scale (HAM-A) were used. Results: The mean age of the sample was 64.0 ± 11.5 (years ± SD), 61% of participants were female. The prevalence of depressive symptoms was 21%, mainly moderate/severe symptoms (13%). Anxiety symptoms were more common (35%). We found significant univariate association between the depressive symptoms and HbA1c (p = 0.001), suicide attempt (p < 0.001), anxiety (p < 0.001), micro- and macrovascular complication (p = 0.028 and p < 0.001), education (p = 0.001) and place of residence (p = 0.002). In multivariate analysis, however, only BDI score had significant (p = 0.03191) association with glycemic control. Conclusion: Among primary care patients with type 2 diabetes, the prevalence of depressive symptoms was less frequent than anxiety symptoms. More severe depressive symptoms were associated with worse glycemic control.

Serum fetuin-A level is independent of Helicobacter pylori postinfection status in systemic lupus erythematosus.

Helicobacter pylori is a common pathogen causing gastric inflammation and malignancy. Fetuin-A is a multifunctional protein that is involved in the regulation of calcification, insulin resistance and inflammation. Reports on serum levels of fetuin-A in acute H. pylori infection are contradictory. We intended to see whether H. pylori post-infection status has a long-term effect on serum fetuin-A levels in a well-characterized series of systemic lupus erythematosus cases. In this cross-sectional study 117 patients with systemic lupus erythematosus were enrolled. Helicobacter infection status and serum fetuin-A concentration were determined by ELISA and radial immunodiffusion, respectively. H. pylori positive patients had higher serum fetuin-A concentration than negative ones: 517 (456-603) vs. 476 (408-544) mg L-1, median (25-75% percentiles), P = 0.020. No other parameters differed between these groups. During univariate regression analysis fetuin-A levels were associated with Erythrocyte sedimentation rate (ESR), White blood cell count (WBC), C-reactive protein (CRP), serum total protein, albumin, and the SLEDAI index at the time of diagnosis but only serum albumin remained a significant determinant in multivariate regression study.

The relationship between anxiety and diabetes / A szorongás és a diabetes közti kapcsolat.

Összefoglaló. A cukorbetegség és a depresszió kapcsolatáról számos tanulmány született. A szorongás és a diabetes közti összefüggést már kevesebben vizsgálták, pedig jelentos szerepük van a szorongásos kórképeknek is, hiszen nagyon gyakori a két betegség együttes elofordulása. A diabetes már önmagában is nagy betegségterhet jelent a betegek számára, a társuló pszichiátriai kórképek pedig tovább rontják a kezelés minoségét, ezért fontos a korai felismerésük és kezelésük. Jelen összefoglaló közleményünk célja a szorongásos kórképek és elsosorban a 2-es típusú cukorbetegség közti összefüggés feltárása. Több elmélet született a köztük lévo kapcsolat magyarázatára. Egyesek szerint szerepet játszhat benne a közös etiológiai háttér, mások szerint a cukorbetegség diagnózisa és a gondozásával kapcsolatos feladatok vezetnek szorongáshoz. Megint mások pedig ellentétes irányból vizsgálva a köztük lévo kapcsolatot, arra a megállapításra jutottak, hogy a szorongás különbözo fiziológiai mechanizmusokon keresztül vezethet cukorbetegséghez. A szorongás és a diabetes közti kapcsolat irányától függetlenül javasolt a depresszió mellett a szorongásnak a szurése és minél korábbi kezelése a cukorbetegek körében, így csökkennének a komorbiditásból származó szövodmények, a kezelési nehézségek, javulna a betegek életminosége és a terápiával való együttmuködésük. Orv Hetil. 2021; 162(31): 1226-1232. Summary. The relationship between diabetes and depression has been evaluated in numerous studies. The association between diabetes and anxiety was less investigated, although the importance of anxiety disorders is underlined by its frequent co-occurrence with diabetes. Diabetes alone carries a significant disease burden for patients. Comorbidity with psychiatric disorders deteriorates the quality of care, therefore early treatment and diagnosis of these conditions are essential. The aim of the present review is to outline the relationship between anxiety and mainly type 2 diabetes. There are several theories to explain the relationship between them. Some researchers suggest that common etiological background may play a role in their co-occurrence, some believe that the diagnosis of diabetes and the burden of self-management lead to anxiety, while others - investigating the relationship from the opposite direction - suggest that anxiety leads to diabetes through physiological mechanisms. Independently of the direction of the relationship, screening for anxiety and timely treatment among diabetic patients may decrease the risk of complications, the difficulty in treatment arising from the co-occurrence of these two conditions and may improve patients' quality of life and adherence to therapy.

Salivary IL-6 mRNA is a Robust Biomarker in Oral Squamous Cell Carcinoma.

Salivary IL-6 mRNA was previously identified as a promising biomarker of oral squamous cell carcinoma (OSCC). We performed a multi-center investigation covering all geographic areas of Hungary. Saliva from 95 patients with OSCC and 80 controls, all Caucasian, were collected together with demographic and clinicopathological data. Salivary IL-6 mRNA was quantified by real-time quantitative PCR. Salivary IL-6 protein concentration was measured by enzyme-linked immune-sorbent assay. IL-6 protein expression in tumor samples was investigated by immunohistochemistry. Normalized salivary IL-6 mRNA expression values were significantly higher (p < 0.001) in patients with OSCC (mean ± SE: 3.301 ± 0.885) vs. controls (mean ± SE: 0.037 ± 0.012). Differences remained significant regardless of tumor stage and grade. AUC of the ROC curve was 0.9379 (p < 0.001; 95% confidence interval: 0.8973-0.9795; sensitivity: 0.945; specificity: 0.819). Salivary IL-6 protein levels were significantly higher (p < 0.001) in patients (mean ± SE: 70.98 ± 14.06 pg/mL), than in controls (mean ± SE: 12.45 ± 3.29). Specificity and sensitivity of IL-6 protein were less favorable than that of IL-6 mRNA. Salivary IL-6 mRNA expression was significantly associated with age and dental status. IL-6 manifestation was detected in tumor cells and tumor-infiltrating leukocytes, suggesting the presence of a paracrine loop of stimulation. Salivary IL-6 mRNA is one of the best performing and clinically relevant biomarkers of OSCC.

The Diagnosis and Therapy of Helicobacter pylori Infection in Hungary: Comparison of Strategies Applied by Family Physicians and Internists.

BACKGROUND AIMS: Most patients with Helicobacter pylori infection are consulted for the first time by family physicians. We aimed to survey the adherence to the newest guidelines of the management of H. pylori infection in the primary and secondary care settings in Hungary. METHODS: From a total of 793 physicians, 94 trainees in family medicine, 334 family physicians without and 195 with board certification in internal medicine, 87 internists, 78 family paediatricians were invited to take part in the study. Diagnostic and therapeutic attitudes towards H. pylori infection were compared by a voluntary and anonymous questionnaire. RESULTS: Participants test for H. pylori infection in 92.8% of cases with a family history of peptic ulcer or 76.9% of gastric cancer, 68.9% of dyspepsia and 49.9% of non-specific abdominal complaints, before initiation of non-steroidal anti-inflammatory drug (NSAID; 17.3%) and antiplatelet treatment (14.5%), respectively. They confirm the success of eradication therapy in 88.1% mainly by urea breath test. Most of them initiate eradication therapy by themselves and only 22.4% refer their patients to a gastroenterologist. Clarithromycin-based standard triple therapy is the most preferred (62.1%) and only 3.7% choose quadruple combination with bismuth as first-line and 48.1% as second-line therapy. We found significant differences between groups with respect to the physicians' own infection, localization of practice, and sources of information on H. pylori infection. Internists are more likely to clarify H. pylori status before the initiation of NSAID and antiplatelet therapies, initiate second-line therapies and use bismuth compared to the other groups. Family physicians with board certification in internal medicine are also prone to start eradication therapy and less prone to refer patients to a gastroenterologist. Family paediatricians prefer stool antigen determination, screen family members and prefer gastroenterologist consultation more often, and use bismuth less frequently than the other groups. Family physicians with previous infection check for H. pyloriinfection more frequently before the initiation of NSAID treatment and are more likely to use histology to detect H. pylori. Postgraduate trainings were the most popular source of information. CONCLUSION: The adherence to the recent recommendations of current guidelines is moderate. There is a need to increase adherence to current recommendations by family physicians and internists.

[Co-occurrence of diabetes and depression, their potential bidirectional association and the significance of their screening]. / A diabetes és a depresszió együttes elofordulása, lehetséges kétirányú kapcsolata és szurésük jelentosége.

Diabetes and depression are considered global epidemics. Both have multifactorial aetiologies, including external, environmental factors and internal factors in connection with physiological processes as well as genetic variants triggering disease onset. Although the co-occurrence of diabetes and depression is well described, the mechanisms underlying these diseases and their interactions are still not entirely revealed. The authors aimed to present known and potential explanations of the co-occurrence of these diseases and to highlight the importance of their timely diagnosis and effective treatment, as their co-occurrence may increase morbidity and mortality. Screening for depression among diabetes patients and for diabetes among patients with depression may decrease the incidence of complications and consequences of this comorbidity and may foster more effective treatment. General practitioners play a key role in the care of both diseases by providing timely diagnosis and adequate treatment potentially leading to a better quality of life, slower disease progression and decreased risk of complications.

Serum fetuin-A, tumor necrosis factor alpha and C-reactive protein concentrations in patients with hereditary angioedema with C1-inhibitor deficiency.

BACKGROUND AND AIMS: Hereditary angioedema with C1-inhibitor deficiency (C1-INH-HAE) is characterized by localized, non-pitting, and transient swelling of submucosal or subcutaneous region. Human fetuin-A is a multifunctional glycoprotein that belongs to the proteinase inhibitor cystatin superfamily and has structural similarities to the high molecular weight kininogen. Fetuin-A is also known a negative acute phase reactant with anti-inflammatory characteristics. In this study we aimed to determine serum fetuin-A, C-reactive protein (CRP) and tumor necrosis factor alpha (TNFα) concentrations in patients with C1-INH-HAE during symptom-free period and during attacks and compare them to those of healthy controls. Further we analyzed possible relationship among these parameters as well as D-dimer levels which was known as marker of HAE attacks. PATIENTS AND METHODS: Serum samples of 25 C1-INH-HAE patients (8 men, 17 women, age: 33.1 ± 6.9 years, mean ± SD) were compared to 25 healthy controls (15 men, 10 women, age: 32.5 ± 7.8 years). Serum fetuin-A and TNFα concentrations were determined by ELISA, CRP and D-dimer by turbidimetry. RESULTS: Compared to healthy controls patients with C1-INH-HAE in the symptom-free period had significantly decreased serum fetuin-A 258 µg/ml (224-285) vs. 293 µg/ml (263-329), (median (25-75% percentiles, p = 0.035) and TNFα 2.53 ng/ml (1.70-2.83) vs. 3.47 ng/ml (2.92-4.18, p = 0.0008) concentrations. During HAE attacks fetuin-A levels increased from 258 (224-285) µg/ml to 287 (261-317) µg/ml (p = 0.021). TNFα and CRP levels did not change significantly. We found no significant correlation among fetuin-A CRP, TNFα and D-dimer levels in any of these three groups. CONCLUSIONS: Patients with C1-INH-HAE have decreased serum fetuin-A concentrations during the symptom-free period. Given the anti-inflammatory properties of fetuin-A, the increase of its levels may contribute to the counter-regulation of edema formation during C1-INH-HAE attacks.

Perceived cardiovascular risk and attitude towards lifestyle change.

Background: Cardiovascular diseases are prominent cause of death. Lifestyle change is effective in decreasing mortality. Perception of patients' cardiovascular risk by physicians is a drive for following preventive recommendations. Whether the hazard perceived by patients influences their attitude towards lifestyle is uncertain. Objective: We hypothesized that high perceived risk would be associated with a stronger determination for lifestyle change, while incorrectly optimistic patients would be less motivated. Methods: Two hundred patients visiting their family physicians were asked to fill out a questionnaire about demographic, clinical and lifestyle characteristics, about their attitude towards lifestyle change and their estimation of their cardiovascular risk. Actual risk was estimated by family physicians based on the national guideline. Results: Questionnaires were completed by 80.5% (161/200) of patients approached. Patients underestimated their risk (P < 0.001), mainly because high-/very high-risk patients classified themselves into lower risk categories. The majority of patients were planning a lifestyle change, losing weight being the most popular goal. It was the priority even for some normal weight subjects and for smokers, too. Perceived risk played a marginal role as a determinant of lifestyle change. Underestimation of perceived risk had no effect on patients' motivation. Self-rated obesity was the predictor of three out of five means of change (weight loss, diet, physical activity). Conclusion: Perceived cardiovascular risk and incorrect optimism about this hazard have minimal, if any, influence on attitude towards lifestyle change. Patients' motivation seems not to be primarily health related.

Salivary proteome profiling of oral squamous cell carcinoma in a Hungarian population.

Oral squamous cell carcinoma (OSCC) is the seventh most common malignancy and the ninth most frequent cause of cancer death in Europe. Within Europe, Hungary has one of the highest rates of OSCC incidence and mortality. Thus, there is an urgent need to improve early detection. Saliva, as a readily available body fluid, became an increasingly important substance for the detection of biomarkers for many diseases. Different research groups have identified salivary biomarkers specific for OSCC for different countries. In this study, saliva samples of Hungarian patients with OSCC were studied to discover disease-specific and perhaps region-specific biomarkers. LC-mass spectrometry (MS)/MS analysis on a linear ion trap-Orbitrap mass spectrometer was used for qualitative and quantitative salivary protein profiling. More than 500 proteins were identified from saliva by shotgun proteomics. The up- and downregulated proteins in the saliva of patients with OSCC highlighted the importance of protein-protein interaction networks involving the immune system and proteolysis in disease development. Two potential biomarkers from our shotgun analysis and a third candidate reported earlier by a Taiwanese group were further examined by ELISA on a larger reference set of samples. Resistin, a biomarker reported in Taiwan but not validated in our study, highlights the necessity of application of standardized analysis methods in different ethnic or geographical populations to identify biomarkers with sufficient specificity and sensitivity.

Association of PPAR Alpha Intron 7 G/C, PPAR Gamma 2 Pro12Ala, and C161T Polymorphisms with Serum Fetuin-A Concentrations.

BACKGROUND: Both peroxisome activator proteins (PPARs) and fetuin-A play a role in lipid and glucose metabolism. AIMS: We investigated whether PPARα intron 7 G2468/C and PPARγ2 Pro12Ala and PPARγ exon 6 C161T polymorphisms are associated with serum fetuin-A concentrations. PATIENTS AND METHODS: The PPARα intron 7 G/C polymorphism was studied in cohort 1 (79 reference individuals, 165 postinfarction patients). The two PPARγ polymorphisms were investigated in cohort 2 (162 reference individuals, 165 postinfarction patients). Fetuin-A levels and PPAR polymorphisms were determined by radial immunodiffusion and polymerase chain reaction-restriction fragment length polymorphism techniques. RESULTS: The C allele variant of PPARα intron 7 G2467C was associated with higher fetuin-A levels (p = 0.018). Postinfarction status (p = 0.001), PPARα intron 7 GG/GC/CC genotypes (p = 0.032), and the C allele (p = 0.021) were the strongest determinants of fetuin-A concentration in a multiple regression model. Higher fetuin-A levels were associated with the Pro variant of PPARγ2 (p = 0.047). Postinfarction status (p = 0.041) and BMI (p < 0.001) but not PPARγ2 Pro were the strongest determinants of fetuin-A concentrations. PPARγ exon 6 C161T genotypes were not associated with fetuin-A levels. CONCLUSIONS: Fetuin-A was determined mainly by the PPARα intron 7C allele and postinfarction status in cohort 1 and the BMI and postinfarction in cohort 2. The PPARα intron 7C and PPARγ2 Pro variants are associated with fetuin-A levels.

The proteomic profile of a mouse model of proliferative vitreoretinopathy.

Proliferative vitreoretinopathy (PVR) develops as a complication of retinal detachment surgery and represents a devastating condition leading to serious vision loss. A good animal model that permits extensive functional studies and drug testing is crucial in finding better therapeutic modalities for PVR. A previously established mouse model, using dispase injection, was analyzed from the proteomic point of view, examining global protein profile changes by 2D electrophoresis, image analysis and HPLC-tandem mass spectrometry-based protein identification. The easy applicability of the mouse model was used to study the role of transglutaminase 2 (TG2) in PVR formation by proteomic examination of dispase-induced TG2 knockout vitreous samples. Our data demonstrate that, despite the altered appearance of crystallin proteins, the lack of TG2 did not prevent the development of PVR.

Proteomic analysis of protein phosphatase Z1 from Candida albicans.

Protein phosphatase Z is a "novel type" fungus specific serine/threonine protein phosphatase. Previously our research group identified the CaPPZ1 gene in the opportunistic pathogen Candida albicans and reported that the gene deletion had several important physiological consequences. In order to reveal the protein targets and the associated mechanisms behind the functions of the phosphatase a proteomic method was adopted for the comparison of the cappz1 deletion mutant and the genetically matching QMY23 control strain. Proteins extracted from the control and deletion mutant strains were separated by two-dimensional gel electrophoresis and the protein spots were stained with RuBPS and Pro-Q Diamond in order to visualize the total proteome and the phosphoproteome, respectively. The alterations in spot intensities were determined by densitometry and were analysed with the Delta2D (Decodon) software. Spots showing significantly different intensities between the mutant and control strains were excised from the gels and were digested with trypsin. The resulting peptides were identified by LC-MS/MS mass spectrometry. As many as 15 protein spots were found that exhibited significant changes in their intensity upon the deletion of the phosphatase and 20 phosphoproteins were identified in which the level of phosphorylation was modified significantly in the mutant. In agreement with previous findings we found that the affected proteins function in protein synthesis, oxidative stress response, regulation of morphology and metabolism. Among these proteins we identified two potential CaPpz1 substrates (Eft2 and Rpp0) that may regulate the elongation step of translation. RT-qPCR experiments revealed that the expression of the genes coding for the affected proteins was not altered significantly. Thus, the absence of CaPpz1 exerted its effects via protein synthesis/degradation and phosphorylation/dephosphorylation. In addition, our proteomics data strongly suggested a role for CaPpz1 in biofilm formation, was confirmed experimentally. Thus our unbiased proteomic approach lead to the discovery of a novel function for this phosphatase in C. albicans.

[What do family medicine trainees think about gratitude payment?] / Mit gondolnak a családorvos-rezidensek a hálapénzrol?

INTRODUCTION: The issue of gratuity is one of the most important health policy issues in Hungary. AIM: The authors' aim is to investigate the attitude of Hungarian family medicine trainees towards gratitude payment. METHOD: Quantitative, paper-based survey among trainees from four Departments of Family Medicine in Hungary (n = 152). RESULTS: More than 50 percent of the residents do not approve of accepting gratitude money. Men (p<0.026), and graduating residents accept it significantly more often (p<0.036) while doctors with children tend to accept it more frequently (p<0.051). They think that the reason for this phenomenon is the lack of proper care (65%), vulnerability and the sense of real gratitude patients feel (52%). According to the participants, the least influencing factor was the low salary of physicians (14.4%). They believe that accepting gratuity is a corruption, and it's humiliating for doctors (80-80%). CONCLUSION: Family medicine residents approve of gratitude money even less as compared to the results of previous studies, but related to other gratitude payment issues we have found similar opinions.

Proteomics investigation of OSCC-specific salivary biomarkers in a Hungarian population highlights the importance of identification of population-tailored biomarkers.

Oral squamous cell carcinoma (OSCC) accounting for about 90% of malignant oral lesions is the 6th most common malignancy worldwide. Diagnostic delay may contribute to dismal survival rate therefore, there is a need for developing specific and sensitive biomarkers to improve early detection. Hungarian population occupies the top places of statistics regarding OSCC incidence and mortality figures therefore, we aimed at finding potential salivary protein biomarkers suitable for the Hungarian population. In this study we investigated 14 proteins which were previously reported as significantly elevated in saliva of patients with OSCC. In case of IL-1α, IL-1ß, IL-6, IL-8, TNF-α and VEGF a Luminex-based multiplex kit was utilized and the salivary concentrations were determined. In case of catalase, profilin-1, S100A9, CD59, galectin-3-bindig protein, CD44, thioredoxin and keratin-19, SRM-based targeted proteomic method was developed and the relative amount of the proteins was determined in the saliva of patients with OSCC and controls. After several rounds of optimization and using stable isotope-containing peptides, we developed an SRM-based method for rapid salivary protein detection. The validation of the selected potential biomarkers by ELISA revealed salivary protein S100A9 and IL-6 as useful protein biomarkers for OSCC detection improving the diagnostic accuracy for OSCC in the Hungarian population.A noninvasive diagnostic method to detect biomarkers useful for the early diagnosis of OSCC was developed. This can be an attractive strategy in screening saliva samples collected in a nation-wide multi-centric study in order to decrease morbidity, mortality, to enhance survival rate and to improve quality of life. The heterogeneity of protein biomarkers found in different ethnic groups presented in the literature highlights the importance of identification of population-tailored protein biomarkers.

[A családorvosok alvási apnoéval kapcsolatos ismeretei és attitudjei. Megvalósul-e az OSAS szurése a jármuvezetok egészségi alkalmasságának vizsgálata során?] / A családorvosok alvási apnoéval kapcsolatos ismeretei és attitudjei. Megvalósul-e az OSAS szurése a jármuvezetok egészségi alkalmasságának vizsgálata során?

BACKGROUND AND PURPOSE: Obstructive sleep apnea syndrome (OSAS) without treatment can cause serious cardiovascular, cardiorespiratory, neurological and other complications. Family physicians have an important role in recognizing the disease. The aim of the study is to assess the knowledge and attitude of family physicians related to sleep apnea. Whether OSAS screening is realized during the general medical checkup for drivers. METHODS: In the cross-sectional study we used a validated OSAKA questionnaire in mandatory continuous medical education courses, supplemented with four additional questions. RESULTS: 116 family physicians and 103 family medicine residents filled out the questionnaire. Hungarian family physicians, especially male doctors lack the adequate knowledge of sleep apnea. The average score of female physicians was significantly higher than that of males (13.4±1.8 vs. 11.7±2.6, p=0.005). The more specializations the doctor has, the higher the score. Zero or one special examination holders reached 12.5±2.3 points, two special examination holders 12.7±2.2 points. three or four special examination holders reached 14.0±2.1 (p=0.05). Residents' average score was 12.1±2.4 points, which is higher than that of family doctors (p=0.012). Female residents also had higher average points than male residents (12.6±2.0 vs. 11.3±2.7; p=0.008). The size, location and type of the practice or the doctor's age did not show any statistically significant correlation with the number of points achieved. According to our regression analysis, corrected to variables in the model, we found correlation between gender and medical knowledge, but there was no correlation between age, number of specialities, body mass index and the theoretical knowledge of the doctors. In terms of attitude female GPs had higher average scores than male GPs (3.5±0.6 vs. 2.9±0.6, p<0.001). Despite the modification of the 13/1992 regulation only 39% of the practices carried out regularly the required OSAS screening as part of the medical examination for a driving licence. CONCLUSION: Despite the high prevalence and clinical importance of OSAS, GPs often do not recognize sleep apnea and they have difficulty in treating their patients for this problem.

Quantitative body fluid proteomics in medicine - A focus on minimal invasiveness.

Identification of new biomarkers specific for various pathological conditions is an important field in medical sciences. Body fluids have emerging potential in biomarker studies especially those which are continuously available and can be collected by non-invasive means. Changes in the protein composition of body fluids such as tears, saliva, sweat, etc. may provide information on both local and systemic conditions of medical relevance. In this review, our aim is to discuss the quantitative proteomics techniques used in biomarker studies, and to present advances in quantitative body fluid proteomics of non-invasively collectable body fluids with relevance to biomarker identification. The advantages and limitations of the widely used quantitative proteomics techniques are also presented. Based on the reviewed literature, we suggest an ideal pipeline for body fluid analyses aiming at biomarkers discoveries: starting from identification of biomarker candidates by shotgun quantitative proteomics or protein arrays, through verification of potential biomarkers by targeted mass spectrometry, to the antibody-based validation of biomarkers. The importance of body fluids as a rich source of biomarkers is discussed. SIGNIFICANCE: Quantitative proteomics is a challenging part of proteomics applications. The body fluids collected by non-invasive means have high relevance in medicine; they are good sources for biomarkers used in establishing the diagnosis, follow up of disease progression and predicting high risk groups. The review presents the most widely used quantitative proteomics techniques in body fluid analysis and lists the potential biomarkers identified in tears, saliva, sweat, nasal mucus and urine for local and systemic diseases.

[Opinions of Hungarian family physicians and residents on vocation and informal payment]. / Hivatással és hálapénzzel kapcsolatos vélekedések a magyarországi családorvosok és családorvos rezidensek körében.

INTRODUCTION: The changing of the family medicine can be observed in the New Millennium. Migration, the aging of the healers and informal payment are crucial to the human resource crisis of the health sector. AIM: The aim of this study was to investigate the family physicians' and residents' opinions about the vocation and informal payment. METHOD: Exploratory, quantitative study was carried out among family physicians (n = 363) and family physician residents (n = 180). The central questions of the study were the vocation, the income and the informal payment. RESULTS: The most decisive factors of the carrier choice were altruism, service and responsibility. Residents were significantly rejective (19.7% vs. 38.3%, p<0.001) about informal payment. They would accept smaller amounts of informal payment (14.3% vs. 8.9%, p<0.034), and would spend it on praxis development (1.4% vs.9.4% p<0.023). CONCLUSIONS: The attitudes of family physicians and residents are the same in case of the vocation, but on the issue of informal payment, the two generations have different opinions. Orv.
