Összefoglaló. Bevezetés A családorvosok testi, lelki egészségi állapota hatással van a munkavégzésükre, a betegellátás minőségére, ezáltal a társadalom egészségmutatóira is. Az életmód pedig az egyik legjelentősebb, egészségi állapotot befolyásoló tényező. Célkitűzés A vizsgálat célja a magyar háziorvosok egészségi állapotának és az azt befolyásoló életmódtényezőknek a felmérése. Módszer Keresztmetszeti vizsgálat. Kvantitatív, papíralapú felmérés családorvosok körében (n = 569, életkor 54 ± 10 év, nők 42%). Eredmények A háziorvosok 61%-a túlsúlyos vagy elhízott, 88%-ának a vércukorszintje ≤5,5 mmol/l. A résztvevők 50%-a legalább heti rendszerességgel végez testmozgást, 20%-uk egyáltalán nem. A háziorvosok 13%-a dohányzik jelenleg, 5%-a tekinthető nagyivónak. Enyhe fokú depressziós tünetegyüttes 19%-uknál, közepes fokú 6%-uknál, súlyos fokú 5%-uknál fordult elő. A súlyos fokú kiégés mindkét nemben, mindhárom dimenzióban 18–39% volt. Következtetés A magyar háziorvosok általános egészségi állapota nem mondható j significant problem among family physicians. Monitoring and caring for their mental health is a key factor in the effective health care system.

The urothelium has a very slow turn-over under normal conditions but is capable of extremely fast response to injury. learn more During regeneration urothelium either restores normal function or undergoes altered differentiation pathways, the latter being the cause of several bladder diseases. In this review, we describe the structure of the apical plasma membrane that enables barrier function, the role of urothelium specific proteins uroplakins and the machinery for polarized membrane transports in terminally differentiated superficial umbrella cells. We address key markers, such as keratins, cancer stem cell markers, retinoic acid signalling pathway proteins and transient receptor potential channels and purinergic receptors that drive normal and altered differentiation in bladder cancer and bladder pain syndrome. Finally, we discuss uncertainties regarding research, diagnosis and treatment of bladder pain syndrome. Throughout the review, we emphasise the contribution of immunohistochemistry in advancing our understanding of processes in normal and diseased bladder as well as the most promising possibilities for improved bladder cancer and bladder pain syndrome management.During aging, skeletal muscle is affected by sarcopenia, a progressive decline in muscle mass, strength and endurance that leads to loss of function and disability. Cell nucleus dysfunction is a possible factor contributing to sarcopenia because aging-associated alterations in mRNA and rRNA transcription/maturation machinery have been shown in several cell types including muscle cells. In this study, the distribution and density of key molecular factors involved in RNA pathways namely, nuclear actin (a motor protein and regulator of RNA transcription), 5-methyl cytosine (an epigenetic regulator of gene transcription), and ribonuclease A (an RNA degrading enzyme) were compared in different nuclear compartments of late adult and old mice myonuclei by means of ultrastructural immunocytochemistry. In all nuclear compartments, an age-related decrease of nuclear actin suggested altered chromatin structuring and impaired nucleus-to-cytoplasm transport of both mRNA and ribosomal subunits, while a decrease of 5-methyl cytosine and ribonuclease A in the nucleoli of old mice indicated an age-dependent loss of rRNA genes. These findings provide novel experimental evidence that, in the aging skeletal muscle, nuclear RNA pathways undergo impairment, likely hindering protein synthesis and contributing to the onset and progression of sarcopenia.As a vital male accessory reproductive gonad, the prostate requires vascular endothelial growth factors for promoting its growth and development. In this study, we investigated the localizations and expressions of vascular endothelial growth factor (VEGF) and its receptors including VEGF-receptor1 (VEFGR1) and VEGF-receptor2 (VEGFR2) in the prostate of the wild ground squirrels during the breeding and the non-breeding seasons. The values of total prostate weight and volume in the breeding season were higher than those in the non-breeding season. Histological observations showed that the exocrine lumens of the prostate expanded in the breeding season and contracted in the non-breeding season. The mRNA expression levels of VEGF and VEGFR2 in the prostate were higher in the breeding season than those in the non-breeding season, but the mRNA expression level of VEGFR1 had no significant change between the breeding and non-breeding seasons. Immunohistochemical results revealed that VEGF, VEGFR1 and VEGFR2 were presented in epithelial and stromal cells during the breeding and non-breeding seasons. In addition, the microvessels of the prostate were widely distributed and the number of microvessels increased obviously in the breeding season, while decreased sharply in the non-breeding season. These results suggested that expression levels of VEGF and VEGFR2 might be correlated with seasonal changes in morphology and functions of the prostate, and VEGF might serve as pivotal regulators to affect seasonal changes in the prostate functions of the wild male ground squirrels via an autocrine/paracrine pathway.Maintaining a balanced and nutritious diet is essential to support optimal health and well-being. However, rates of overweight and obesity in the UK and internationally have risen significantly, alongside increases in food portion sizes. While it can be challenging to work in partnership with patients towards achieving a healthy weight, it is crucial that nurses are able to offer patients advice and support to assist them in following dietary guidelines. This article explores the development and practical application of recommended dietary guidelines such as the Eatwell Guide. It also discusses practical interventions that nurses can use to advise patients on healthy eating, such as using the hands as a guide to portion size.
