OCTOBER 20, 2016

Lege Artis Medicinae - 2016;26(09-10)

[The timely detection of thyroid hormone deficiency is crucial to inhibit the dangerous consequences of related diseases, such as obesity, cardiovascular diseases, type 2 diabetes mellitus, breast cancer, bone wasting, menstruation disturbance, and goitrogenesis. Subclinical hypothyroidism (<10 mU/l TSH) can initiate the above mentioned symptoms and diseases, therefore its early detection and treatment is necessary. The manuscript details from a practical point of view the causes leading to thyroid hormone deficiency, their consequences and gives recommendation for starting the treatment. The increased occurrence of breast and colorectal cancers associated with thyroid hormone deficiency is explained, and the attention to concomitantly elevated prolactin levels is called. Finally, the paper gives proposals for the clinical practice, when we should think of thyroid hormone deficiency and reports on the algorithm of the treatment of subclinical hypo­thyroidism recommended by the European Thyroid Association (ETA) in 2013.]

[“Yesterday no longer exists either…” - End-of-life ethical issues in the care of dementia patients]

HEGEDÛS Katalin

[The number of dementia patiens is rising. Most of them die in various institutions, often after many years of care. The long process of nursing and care entails particular ethical requirements that are built primarily on vulnerability, dignity, and dia-logue. The dialogue, however, is often absent from the care of dementia patients. Do we find - as physicians, patients, relatives - that specific time when the patients can still make decisions about end-of-life treatments in a good mental state? Most patients would like to participate in these decisions. Talking about these issues in the early stage of dementia may help in the great emotional burden of family members and caregivers. Therefore the ethical aim is the ad­vance care planning (ACP) of the end-of-life treatments. The study reviews the latest scientific results, with special regard to resources that may be helpful in the course of conversations between doctor and patient on end-of-life preferences, and in the preparation for decision making. ]

[Physician attitudes concerning complementary and alternative medicine]

ZÖRGŐ Szilvia, GYŐRFFY Zsuzsa

[INTRODUCTION - A crucial challenge for XXI. century health care is the presence of complementary and alternative medicine (CAM). A marked question of professional discourse has been characterizing patient CAM use, yet the attitudes, knowledge, and opinions of physicians have received far less attention. METHODS - This qualitative study involves semi-structured interviews conducted with 45 physicians. The narratives were scrutinized by employing Interpretative Phenomenological Analysis (IPA) via At­las.ti software. RESULTS - The narratives were coded ac­cording to attitudes and opinions concerning CAM, and subsequently participants were placed into 3 main groups. The first group is distinguished by a total rejection of CAM (n=11), while at the other end of the continuum, participants integrated biomedicine with CAM therapies (n=8). Those participants in between the two poles (rejection and integration) were characterized as „acceptance with reservations” and signify a heterogeneous category regarding composition and attitudes. COMMENTS - Most participants in our sample belonged to the „acceptance with reservations” category, that is, physicians who do not employ CAM in their praxis, albeit support their patients should they decide to utilize a CAM modality. Our inquiry aims to serve as a precursor to a quantitative study concerning CAM use.]

[Conversation with the relatives]

ZELENA András, MONOSTORI Dóra

[In our strong opinion in hospitals the efficient conversation among staff and patient and/or relatives is important. We try to draw attention to the psychosocial aspects of pediatric intensive care and the complex and special case of relative-staff communication via the introduction of a clinical case. Various medical experts were involved in the treatment of the infant and all participants witnessed the 4 months long life and the death of the newborn. The case of the intubed patient was painful and stressful for the medical staff. With our case-report, we try to present the spectrum, which forms during the treatment of a sickly born infant and the changes of the relationship of the medical staff and relatives as well as the engrossment of their interpersonal relationship along with the center of their communication problems and solution-finding. Our paper is centered around the psychosocial aspect of the clinical case and we would like to call the attention on how the medical experts communicated with the parents of the infant. ]

[The role of neurohormonal regulation in the development of insulin resistance in chronic stress]

MOLNÁR Ildikó

[The effects of the chronic stress could not be avoided recently. The pathognomic regulation of the neurohormonal events is responsible for the manifestation of diseases such as obesity, cardiovascular diseases, diabetes mellitus type 2, depression, tumors, inflammations, allergy. Two major regulatory systems are involved in the neuroendocrine alterations caused by stress: the hypothalamus-pituitary-adrenal (HPA) axis and the sympathetic nervous systems. The chronic activation of the adrenocortical system leads to insulin resistance and obesity associating with vascular, arteriosclerotic and inflammatory symptoms. The revealing of the pathognomic events on time and the enhanced physical activity may provide the effective prevention of these frequent diseases.]

[BRAIN INSULIN SIGNALLING IN THE REGULATION OF ENERGY BALANCE AND PERIPHERAL METABOLISM]

MICHAELA Diamant

[The unparalleled global rates of obesity and type 2 diabetes, together with the associated cardiovascular morbidity and mortality, are referred to as the "diabesity pandemic". Changes in lifestyle occurring worldwide, including the increased consumption of high-caloric foods and reduced exercise, are regarded as the main causal factors. Central obesity and insulin resistance have emerged as important linking components. Understanding the aetiology of the cluster of pathologies that leads to the increased risk is instrumental in the development of preventive and therapeutic strategies. Historically, skeletal muscle, adipose tissue and liver were regarded as key insulin target organs involved in insulinmediated regulation of peripheral carbohydrate, lipid and protein metabolism. The consequences of impaired insulin action in these organs were deemed to explain the functional and structural abnormalities associated with insulin resistance. The discovery of insulin receptors in the central nervous system, the detection of insulin in the cerebrospinal fluid after peripheral insulin administration and the well-documented effects of intracerebroventricularly injected insulin on energy homeostasis, have identified the brain as an important target for insulin action. In addition to its critical role as a peripheral signal integrating the complex network of hypothalamic neuropeptides and neurotransmitters that influence parameters of energy balance, central nervous insulin signalling is also implicated in the regulation of peripheral glucose metabolism. This review summarizes the evidence of insulin action in the brain as part of the multifaceted circuit involved in the central regulation of energy and glucose homeostasis, and discuss the role of impaired central nervous insulin signalling as a pathogenic factor in the obesity and type 2 diabetes epidemic.]

[Diabetes mellitus and the liver]

BECHER Péter, PATAI Árpád, MÁJER Katalin

[In the past years, the prevention of micro- and macrovascular complications has been the main target of diabetes treatment. Its unfavourable effects on the liver have been forgotten: the accelerated progression of the liver diseaeses and the increased risk of hepatocellular carcinoma. The multimetabolic syndrome leads to non-alcoholic fatty liver diseases (steatosis, steatohepatitis, cirrhosis). On he other hand some types of liver cirrhosis (for example the common alcoholic form) are worsening the insulin resistance, so they may due to a hepatogenous diabetes mellitus, that’s treatment is different and needs more regard, than type 2 diabetes.]

[INSULIN RESISTANCE: FOCUS ON THE ADIPOSE TISSUE]

URICH Elemér

[Insulin resistance is defined as a state of subnormal biological response to normal quantity of insulin. This phenomenon was first described by Hinsworth and Kerr in 1939, however it has come to the centre of interest only in the last two decades. It is the central pathogenetic factor of type 2 diabetes and the more complex clinical entity of metabolic syndrome, consequently also referred to as insulin resistance syndrome. In the background of insulin resistance alterations of the adipose tissue can be observed which clinically means obesity in most of the cases, however, this issue cannot be simplified to obesity only as increase in adipose tissue growth may be beneficial in certain cases. Current article discusses the explanation of this paradox and the pathophysiologic link between adipose tissue and insulin resistance. It also reviews the therapeutic aspects of insulin resistance emphasizing the role of thiazolidinedione type drugs having recently joined the therapeutic palette.]

[Gestational diabetes mellitus and neuropathy: examining the relationship]

STELLA Péter, KERÉNYI ZSUZSA, NÁDASDI Ágnes, TAMÁS GYULA

[BACKGROUND - Little is known about the relationship between gestational diabetes and late diabetes complications. The relationship between these abnormalities was investigated in this study. PATIENTS, METHODS - Besides reclassification of their glucose tolerance, the prevalence and correlating factors of diabetic neuropathy were evaluated in 123 gestational diabetic (GDM) women controlled prior by our team during their pregnancies. 26 pregestational type 2 diabetic patients served as controls. Mean follow-up time was 7.2 years. Vibration perception threshold was measured to diagnose peripheral neuropathy, while cardiovascular autonomic neuropathy was evaluated using the battery of four cardiovascular reflex-tests. RESULTS - From 123 prior GDM women, 63 were characterized as having diabetes (52.9%), while 14 had impaired glucose tolerance (11.8%). Peripheral neuropathy was diagnosed in 23.6 %, parasympathetic neuropathy in 37.4 %, while sympathetic neuropathy was confirmed in 7.3 % of the patients evaluated during follow-up visit. Association between abnormal glucose tolerance and neuropathy was statistically significant only in the case of parasympathetic neuropathy (p=0.0001), and this relationship was independent from elevated BMI, microalbuminuria and the higher rate of hypertension observed in these women (p=0.006). Since the number of abnormal neuropathy tests were also higher than expected in women with normal glucose tolerance, we hypothetised a cross-sectional link between neuropathy and insulin resistance. An additional analysis comfirmed this association between insulin resistance and parasympathetic neuropathy independent of metabolic status of these patients (p=0.005). CONCLUSIONS - The importance of gestational diabetes, which is sometimes underestimated by many clinicians, was highlighted by our study since it projected a high frequency of parasympathetic cardiovascular neuropathy in these patients. This form of diabetes not only projects the development of late onset type 2 diabetes, but could also act as a predictor of late diabetes complications. According to our results diabetic parasympathetic neuropathy may be linked to type 2 diabetes/ insulin resistance syndrome, and could play a role in the excess cardiovascular mortality observed in these patients.]
