[Biomonitoring of lead exposure among workers: the role of the occupational health nurse ]


[Biological monitoring (biomonitoring) in occupational safety and health is the detection of substances (biomarkers) in biological samples of workers, compared to reference values. This article is limited to Lead (Pb) exposures, as it is one of the most important models for biomonitoring of exposure, with the blood Pb concentration as a predominant choice in occupational health. This article examines the nature of and risk factors for lead exposure among workers, the scope of the problem, the legislative and regulatory framework relevant to biomonitoring, and the role of occupational health nurses in promoting a culture of safety to prevent exposures. ]

Matrix metalloproteinases and their tissue inhibitors in relapsing remitting multiple sclerosis: Possible markers and treatment agents


Matrix metalloproteinases (MMPs), which are synthesized by many cell groups and responsible for the destruction of matrix proteins, and endogen tissue inhibitors of MMPs (TIMPs) have a role in the pathogenesis of Multiple Sclerosis (MS) by affecting the blood-brain barrier. We aimed to investigate the role of MMPs and TIMPs in the immunopathogenesis and in the course of multiple sclerosis (MS). We enrolled 25 relapsing remitting MS patients, who had a definite MS diagnosis according to McDonald criteria and 25 healthy subjects similar for age and gender as control group. MMP-9- and TIMP-1 levels were measured twice in patient group (one time during an attack and one in remission) and once in healthy subjects. MMP-9- and TIMP-levels of patients during attack and remission period and MMP-9/TIMP-1 ratio were found significantly higher than in the control subjects. In patient group MMP-9 and TIMP-1 levels and MMP-9/TIMP-1 ratio during attacks were not significantly different than during remission period. However, when subdivided according to their number of attacks, patients with 2 attacks had significantly higher levels during attack period comparing to remission period (p<0.05); in case of patients with more than 2 attacks did not have a statistically significant difference in attack and remission periods. Matrix metalloproteinases are important actors in MS immunopathogenesis, particularly in the early period and inhibitor agents for these enzymes can be used as a treatment option.

Retinal morphological changes during the two years of follow-up in Parkinson’s disease

ATUM Mahmut, DEMIRYÜREK Enes Bekir

The study aims to investigate the relationship between the progression of idiopathic Parkinson’s disease (IPD) and retinal morphology. The study was carried out with 23 patients diagnosed with early-stage IPD (phases 1 and 2 of the Hoehn and Yahr scale) and 30 age-matched healthy controls. All patients were followed up at least two years, with 6-month intervals (initial, 6th month, 12th month, 18th month, and 24th month), and detailed neurological and ophthalmic examinations were performed at each follow-up. Unified Parkinson’s Disease Rating Scale part III (UPDRS Part III) scores, Hoehn and Yahr (H&Y) scores, best-corrected visual acuity (BCVA), intraocular pressure (IOP) measurement, central macular thickness (CMT) and retinal nerve fiber layer (RNFL) thickness were analyzed at each visit. The average age of the IPD and control groups was 43.96 ± 4.88 years, 44.53 ± 0.83 years, respectively. The mean duration of the disease in the IPD group was 7.48 ± 5.10 months at the start of the study (range 0-16). There was no statistically significant difference in BCVA and IOP values between the two groups during the two-year follow-up period (p> 0.05, p> 0.05, respectively). Average and superior quadrant RNFL thicknesses were statistically different between the two groups at 24 months and there was no significant difference between other visits (p=0.025, p=0.034, p> 0.05, respectively). There was no statistically significant difference in CMT between the two groups during the follow-up period (p> 0.05). Average and superior quadrant RNFL thicknesses were significantly thinning with the progression of IPD.

[The role of APN in the Care of Patients with High Blood Pressure]

VÖRÖS Tünde, PAKAI Annamária, SZEBENI-KOVÁCS Gyula, SZABÓNÉ Bálint Ágnes, OLÁH András

[Internationally the role of Advanced Practice Nurses (APN) has grown a lot in the treatment for high blood pressure. The tasks of Advanced Practice Nurses with an advanced degree include the observation, following, diagnostics, medicinal treatment, health education, education of patients, coordination of care, checking of performance and improvement of quality. In Hungary the family doctors do the care of people with hypertonia in the primary care. Because of the number of patients who must be treated every day comes less time per capita in the care. For a high number of acute patients must be cared and for this reason less time remains for the care of chronic patients. In Hungary the education for Advanced Practice Nurse (APN) with an advanced degree has started in autumn 2017. The first of these nurses will get out of the education in February 2019. Due to their education they will be able to care acute illnesses in practices of family doctors and in communities of practice. Besides they will be able to explore, care and follow chronic patients. ]

[Survey of Medication Habits in Hypertensive Adults]

VARGA Bernadett, FUSZ Katalin, CSIMA Melinda, LUKÁCS-HORVÁTH Marianna, DEÁK András, STROMAJER-RÁCZ Tímea

[Hypertension is the best known risk factor in development of cardiovascular diseases and stroke. Survey has assessed –in hypertensive patients over 40, - the illness representation, lifestyle and medicine taking habits. Quantitative, cross-section descriptive research was conducted in 2017 with online questionnaire among hypertensive people over 40 (n=267) using shortened version of Brief Illness Perception Questionnaire, Morisky Medication Adherence Scale (8-item) and our questionnaire. Therapy adherence is typical for older individuals in surveyed population. (r= 0,26; p<0,001). Who were advised by general practitioners (GP) to implement lifestyle changes show more inclination following therapy. (p=0,032). Those with higher blood pressure (r-0,18; p=0,003) has harder time living with hypertension. (r=0,15; p=0,014). Quality of living with hypertonia and therapy adherence can be influenced by health behaviour and the information provided by general practitioners (GP). Beside the, general practitioners (GP) advanced practice nurse can have significant role in increasing the level of health behaviour and therapy adherence. ]

[Complication of the Metabolic Syndrome in Women with Polycystic Ovary Syndrome]

KOMLÓSI Kálmánné, KISS Sarolta, FERENCZY Mónika, MÁTÉ-PÓHR Kitti, PAKAI Annamária

[In our research we compared whether pregnant women with polycystic ovary syndrome or the mothers who were healthy through pregnancy has a higher risk to develop high BMI, metabolic syndrome, preeclampsia, polyhydramnion and macrosomia. Our research is a retrospective, cross-sectional study. In the random sampling within the target group, the target group was diagnosed with PCOS (n=50) and the control group was mothers who had undergone uninterrupted pregnancy (n=50). The exclusion criterion is the coexistence of other endocrine disease that may affect the parameters under consideration, in addition to the control group the diagnosis of PCOS. With IBM SPSS for Windows 22.0, we applied two-sample T-test and Khi2 test (p<0.05). The BMI values ​​measured in the PCOS study group are higher than in the control group (p<0,05). Pregnant women with PCOS has a higher risk of developing high blood pressure, and high cholesterol (p<0,05). The difference between the two groups can not be considered significant for the development of proteinuria and oedema. Emphasis should be placed on PCOS gravid care, early detection of metabolic disturbances, accurate documentation, and elimination of complications and illnesses associated with the disease.]

[Possibility of ARNI (angiotensin receptor-neprilysin inhibitor) treatment in hypertension]


[The natriuretic peptide (NP) is an important endocrine, autocrine and paracrine system that is in constant interaction with RAAS and the sympathetic nervous system in order to ensure a continuous cardio-renal homeostasis. In abnormal conditions – if the pressure/volume load develops in the heart or there are some disorder in the vascular tone or in sodium-water balance, the NP system triggers the body’s defense mechanism. The neutral endopeptidase (NEP) inactivates the vasodilator NPs, bradykinin and vasoconstrictor angiotensin II and endothelin I as well. From this knowledge, the idea that inhibition of the effect of NEP (NEPg) offers a potentially beneficial option in the treatment of heart failure and hypertension was initiated, only the stimulatory effect of angiotensin II needs to be blocked. After a lengthy search, they arrived at a dualacting molecule with a beneficial effect of NEP inhibition (secubitrile) and the angiotensin II AT1 receptor antagonist valsartan (ARNI). Several clinical studies have shown that ARNI alone and in combination with other antihypertensive agents significantly reduces SBP and DBP in hypertensive patients. Its effect is also present in isolated systolic hypertension and in chronic kidney disease with high risk. Do not administer with an ACE inhibitor. Based on clinical experience to date, there is a logic expectation that ARNI will also be classified as a useful antihypertensive agent in the near future.]

[Risk of nonsteroidal antiinflammatory drugs. Focus on aceclofenac]


[Nonsteroidal antiinflammatory drugs (NSAIDs) are among the most frequently used pharmaceuticals. Nevertheless, a number of studies emphasized that NSAIDs were damaging not only the gastrointestinal (GI), but also the cardiovascular (CV) system, could increase the blood pressure, the frequency of coronary events (angina, myocardial infarction) and stroke incidence, as well as they might deterio­rate renal functions. The National Institute for Health and Care Excellence (NICE) did not find evidence that administering NSAIDs could increase the risk of developing COVID-19 or worsened the condition of COVID-19 patients. However, unwanted effects of specific drugs differ substantially in their occurrence and seriousness as well. It seemed to be for a long time that the NSAIDs provoked higher GI-risk was closely related to the COX1/COX2 selectivity, like the cardiovascular (CV) risk to the COX2/COX1 selectivity, however, the recent data did not prove it clearly. Based on the available literature while pondering the gastrointestinal and cardiovascular adverse events, among all NSAIDs the aceclofenac profile seemed to be the most favourable.]

[Molecular residual tumor monitoring in solid cancers]

SZÁSZ A. Marcell, TOBIÁS Bálint, KÓSA János, LAKATOS Péter

[Blood-based diagnostics has long been used in the oncological practice of solid tumors, but its full potential is just unfolding recently. Quantitative measurement of tumor markers, circulating tumor cells, and some of their products or components have now become available and are part of a multimodal system that provides additive parameters in clinical decision making. The most challenging oncological questions can be answered by the detection, characterization and measurement of circulating free DNA (cfDNA), which, due to its growing importance, bears the potential of incorporation into routine practice. In this overview, we review the „blood impressions” of solid tumors and present the most promising results in different patient groups, especially in lung, breast, colon, and bladder tumors, which are also valid for other solid tumors.]

[Biological clock and cancer]


[In the present paper, we are giving a review about the circadian rhythm of the biological rhythm, its regulation and relation to tumorigenesis. The circadian rhythm is an approximately 24-hour cycle in biochemical, physiological processes in organisms from unicellular to vertebrates. This biological rhythm is generated by the synchronization of our endogenous clocks and the light as the main “Zeitgeber”. The nucleus suprachiasmaticus (SCN) of the hypothalamus is the region, which is considered to be the circadian “main clock” of the organism and is responsible for coordinating peripheral clocks in different organ systems. At the cellular level, the regulation of the circadian rhythm is basically provided by the so-called “circadian locomotor output cycles kaput” the CLOCK genes. The discovery of those cellular mechanisms was awarded with Nobel Prize in 2017. The CLOCK genes, acting on other effector genes, regulate diurnal rhythm of protein synthesis. More and more data are available, which suggest that there is an association between circadian genes and tumor development. Furthermore, many studies show a link between the shift work and the development of breast and prostate cancer and between mutations in some circadian genes and development of carcinomas. More data suggest a relationship between tumor metabolism and CLOCK genes and their regulations. Based on all these data, the circadian rhythm, so the time of day, may need to be taken into account during cancer therapy.]
