La especialidad clínica de la endocrinología lleva ya más de medio siglo en nuestro país, y si nos ponemos a ver la actividad de algunos precursores, esta historia bien puede remontarse al siglo XIX.

El académico Antonio Ucrós Cuellar se puso en la tarea de recopilar las actuaciones de los especialistas en problemas hormonales y en las actividades de las asociaciones científicas de este ramo de la medicina y para ello contó con la ayuda editorial de los endocrinólogos y discípulos suyos, Eric Hernández y Stella Acosta.

Ucrós ha participado personalmente en el devenir histórico de la endocrinología en Colombia, como investigador de la problemática del bocio, como fundador de la Asociación Colombiana de Endocrinología y de la sección de endocrinología del Hospital de San José, que recientemente cumplió sus Bodas de Oro, y en la cual se han formado numerosos y distinguidos especialistas que ejercen en el país su profesión.

Comentar esta obra viene como anillo al dedo en este número especial sobre endocrinología que publica la revista “Medicina” de la Academia. Este libro de 230 páginas recoge en su parte inicial los antecedentes históricos y los estudios sobre el bocio en el país que el autor tan elegantemente lideró, finaliza esta parte inicial con su propia versión de la endocrinología en Colombia, que comienza con él y otros eminentes especialistas como Hernán Mendoza Hoyos, Tomás Quintero, Alonso Gutiérrez, Jaime Cortázar, Efraím tero, Mario Sánchez Medina (en el campo de la diabetes, Iván Molina en Medellín, Alberto Jamis en Barranquilla, y el importante grupo de Cali donde figuraron entre otros Eduardo Gaitán, Heins Wahner (actualmente en la Clínica Mayo, William Jubiz y Matilde de Bernal, todos de talla internacional.

Mi interés por la endocrinología se inició con las magistrales clases de Mendoza Hoyos en la Javeriana, sobre el tema de la Fisiología Endocrina

Microbial endocrinology and the microbiota-gut-brain axis.

Science.gov (United States)

Lyte, Mark

2014-01-01

Microbial endocrinology is defined as the study of the ability of microorganisms to both produce and recognize neurochemicals that originate either within the microorganisms themselves or within the host they inhabit. As such, microbial endocrinology represents the intersection of the fields of microbiology and neurobiology. The acquisition of neurochemical-based cell-to-cell signaling mechanisms in eukaryotic organisms is believed to have been acquired due to late horizontal gene transfer from prokaryotic microorganisms. When considered in the context of the microbiota's ability to influence host behavior, microbial endocrinology with its theoretical basis rooted in shared neuroendocrine signaling mechanisms provides for testable experiments with which to understand the role of the microbiota in host behavior and as importantly the ability of the host to influence the microbiota through neuroendocrine-based mechanisms.

The transgender population continues to face challenges in accessing appropriate health care. Adequate training of endocrinologists in this area is a priority. Assess the status of transgender health care education in US endocrinology fellowship training programs and assess knowledge and practice of transgender health among practicing US endocrinologists. Mayo Clinic and the Endocrine Society developed and administered a Web-based anonymous survey to 104 endocrinology fellowship program directors (PDs; members of the Association of Program Directors in Endocrinology, Diabetes and Metabolism) and 6992 US medical doctor members of Endocrine Society. There were 54 total responses from 104 PDs (51.9%). Thirty-five of these 54 programs (72.2%) provide teaching on transgender health topics; however, 93.8% respondents indicated that fellowship training in this area is important. Barriers to provision of education included lack of faculty interest or experience. The most desired strategies to increase transgender-specific content included online training modules for trainees and faculty. Of 411 practicing clinician responders, almost 80% have treated a transgender patient, but 80.6% have never received training on care of transgender patients. Clinicians were very or somewhat confident in terms of definitions (77.1%), taking a history (63.3%), and prescribing hormones (64.8%); however, low confidence was reported outside of the hormonal realm. The most requested methods of education included online training modules and presentation of transgender topics at meetings. Confidence and competence in transgender health needs to increase among endocrinologists. Strategies include the development of online training modules, expansion of formal transgender curricula in fellowship programs, and presentations at national and international meetings.

Shubeska Stratrova, S

2013-01-01

The Clinic of Endocrinology, diabetes and metabolic disorders was founded in 1975 by Prof d-r Alexandar Plashevski. Healthcare, educational and scientific activities in the Clinic of Endocrinology are performed in its departments. The Department for hospitalized diabetic and endocrine patients consists of the metabolic and endocrine intensive care unit, the department for diagnosis and treatment of diabetics and endocrine patients, day hospital, the department for education of diabetic patients, and the national center for insulin pump therapy. The Center for Diabetes was established in 1972 by Prof d-r Dimitar Arsov. In 1975, Prof d-r Alexandar Plasheski broadened the activities of the Center for Diabetes. It was dislocated in 1980, with new accommodation outside the clinic. Since then the Center has consisted of several organized units: two specialist outpatient clinics for diabetic patients, biochemical and endocrine laboratory, sub-departments for: diabetic foot, cardiovascular diagnosis, ophthalmology, and urgent interventions. The Department of Endocrinology and Metabolic Disorders for outclinic endocrine patients was established in 1980, and it integrates the following sub-departments: thyrology, andrology, reproductive endocrinology, obesity and lipid disorders and sub-department for osteoporosis. The educational staff of the Clinic of Endocrinology organizes theoretical and practical education about Clinical Investigation and Internal Medicine with credit transfer system course of study of the Medical Faculty, Faculty of Stomatology, postgraduate studies, specializations and sub-specializations. Symposiums, 3 congresses, schools for diabetes and osteoporosis and continuous medical education were also organized. The Clinic of Endocrinology was initiator, organizer, founder and the seat of several medical associations.

Microbial Endocrinology in the Pathogenesis of Infectious Disease.

Science.gov (United States)

Lyte, Mark

2016-04-01

Microbial endocrinology represents the intersection of two seemingly disparate fields, microbiology and neurobiology, and is based on the shared presence of neurochemicals that are exactly the same in host as well as in the microorganism. The ability of microorganisms to not only respond to, but also produce, many of the same neurochemicals that are produced by the host, such as during periods of stress, has led to the introduction of this evolutionary-based mechanism which has a role in the pathogenesis of infectious disease. The consideration of microbial endocrinology-based mechanisms has demonstrated, for example, that the prevalent use of catecholamine-based synthetic drugs in the clinical setting contributes to the formation of biofilms in indwelling medical devices. Production of neurochemicals by microorganisms most often employs the same biosynthetic pathways as those utilized by the host, indicating that acquisition of host neurochemical-based signaling system in the host may have been acquired due to lateral gene transfer from microorganisms. That both host and microorganism produce and respond to the very same neurochemicals means that there is bidirectionality contained with the theoretical underpinnings of microbial endocrinology. This can be seen in the role of microbial endocrinology in the microbiota-gut-brain axis and its relevance to infectious disease. Such shared pathways argue for a role of microorganism-neurochemical interactions in infectious disease.

Reproductive endocrinology of vitamin D.

Lorenzen, Mette; Boisen, Ida Marie; Mortensen, Li Juel; Lanske, Beate; Juul, Anders; Blomberg Jensen, Martin

2017-09-15

Vitamin D is a versatile hormone with several functions beyond its well-established role in maintenance of skeletal health and calcium homeostasis. The effects of vitamin D are mediated by the vitamin D receptor, which is expressed together with the vitamin D metabolizing enzymes in the reproductive tissues. The reproductive organs are therefore responsive to and able to metabolize vitamin D locally. The exact role remains to be clarified but several studies have suggested a link between vitamin D and production/release of reproductive hormones into circulation, which will be the main focus of this review. Current evidence is primarily based on small human association studies and rodent models. This highlights the need for randomized clinical trials, but also functional animal and human in vitro studies, and larger, prospective cohort studies are warranted. Given the high number of men and women suffering from reproductive problems and abnormal endocrinology research addressing the role of vitamin D in reproductive endocrinology may be of clinical importance.

Endocrinology and Clinical Nutrition are branches of Medicine that deal with the study of physiology of body glands and hormones and their disorders, intermediate metabolism of nutrients, enteral and parenteral nutrition, promotion of health by prevention of diet-related diseases, and appropriate use of the diagnostic, therapeutic, and preventive tools related to these disciplines. Development of Endocrinology and Clinical Nutrition support services requires accurate definition and management of a number of complex resources, both human and material, as well as adequate planning of the care provided. It is therefore essential to know the services portfolio of an ideal Department of Endocrinology and Clinical Nutrition because this is a useful, valid and necessary tool to optimize the available resources, to increase efficiency, and to improve the quality of care.

Science.gov (United States)

Tsutsui, Kazuyoshi

2013-01-15

The Asia and Oceania Society for Comparative Endocrinology (AOSCE) was founded in 1987, when the first congress was held in Nagoya, Japan. The purpose of the AOSCE is to progress scientific activities in the field of comparative endocrinology in Asia and Oceania and to establish a deep relationship among the members. For this purpose, the AOSCE holds a congress or an intercongress symposium every 2 years, which organizes an attractive scientific program covering the latest progress in the broad aspect of comparative endocrinology. 2012 was the 25th anniversary of AOSCE. Our scientific activities have increased dramatically during the past 25 years. The 7th AOSCE congress was held in Kuala Lumpur, Malaysia in 2012. The theme of this congress was "Overcoming challenges in the 21st century". To overcome challenges in the 21st century, we further need to create new research directions in comparative endocrinology from Asia and Oceania. This paper describes a brief history of the AOSCE and also highlights the discovery of gonadotropin-inhibitory hormone (GnIH) and the progress of GnIH research as one of new research directions in comparative endocrinology. In 2000, GnIH was discovered in Japan and now more than 50 laboratories are working on GnIH in the world. The discovery of GnIH has changed our understanding about regulation of the reproductive axis drastically in the past decade. Copyright © 2012 Elsevier Inc. All rights reserved.

Adult and pediatric endocrinologists share responsibility for the transition of youth with type 1 diabetes from pediatric to adult healthcare. This study aimed to increase successful transfers to adult care in subspecialty practices by establishing a systematic health care transition (HCT) process. Providers from the adult and pediatric endocrinology divisions at the University of Rochester Medical Center met monthly to customize and integrate the Six Core Elements (6CEs) of HCT into clinical workflows. Young adult patients with type 1 diabetes having an outpatient visit during a 34-month pre-post intervention period were eligible (N = 371). Retrospective chart review was performed on patients receiving referrals to adult endocrinology (n = 75) to obtain (1) the proportion of patients explicitly tracked during transfer from the pediatric to adult endocrinology practice, (2) the providers' documentation of the use of the 6CEs, and (3) the patients' diabetes control and healthcare utilization during the transition period. The percent of eligible patients with type 1 diabetes who were explicitly tracked in their transfer more than doubled compared to baseline (11% vs. 27% of eligible patients; P<.01). Pediatric providers started to use transition readiness assessments and create medical summaries, and adult providers increased closed-loop communication with pediatric providers after a patient's first adult visit. Glycemic control and healthcare utilization remained stable. Successful implementation of the 6CEs into pediatric and adult subspecialty practices can result in improvements of planned transfers of pediatric patients with type 1 diabetes to adult subspecialty providers. 6CEs = six core elements; AYA = adolescent and young adult; DKA = diabetic ketoacidosis; ED = emergency department; HbA1c = hemoglobin A1c; HCT = health care transition.

Background: Residents' perception on quality of endocrinology training in India is not known. This study aimed to evaluate the perceptions about endocrinology residency programs in India among current trainees as compared to practicing endocrinologists. Methods: Trainees attending a preconference workshop at the annual conference of Endocrine Society of India (ESI) were given a questionnaire designed to evaluate their perceptions on their training. These evaluated the reasons for choosing endocrinology, their experiences during residency, and career plans. Practicing endocrinologists attending ESICON with at least 5-year experience were evaluated as controls. Results: Questionnaires from 63 endocrine trainees and 78 practicing endocrinologists were analyzed. Endocrinology is perceived to be the super-specialty with the best quality of life (QOL) but fair with regard to financial remuneration. Among current trainees, 61.89%, 31.74%, and 34.91% are satisfied with training in clinical endocrinology, laboratory endocrinology, and clinical/translational research, respectively. The corresponding figures for practicing endocrinologists are 71.78%, 25.63%, and 30.75%, respectively. Exposure to national endocrinology conferences during their endocrinology residency was adequate. However, exposure to international endocrinology conferences, research publications, project writing, and grant application are limited. Laboratory endocrinology is rated as the most neglected aspect during endocrine residency. Most of the trainees want to establish their own clinical practice in the long run. Very few trainees (17.46%) wish to join the medical education services. Conclusion: There is a good perception of QOL in endocrinology in spite of average financial remuneration. There is dissatisfaction with the quality of training in laboratory endocrinology and clinical research. Very few endocrine trainees consider academics as a long-term career option in India.

Recently, significant contributions to the study of endocrinology and metabolism have been made. The national contribution, however, has not been reported. The aim of this study was to assess national efforts in the field of endocrinology and metabolism. A Web of Science search was performed using subject categories "endocrinology & metabolism" to identify articles published from 2010 to 2014. The total and per capita numbers of articles and citations were analysed for different countries. A total of 79,394 articles were published on endocrinology and metabolism from 2010 to 2014. Most were published in North America, East Asia, and Europe. The majority (82.28%) were reported by authors in high-income countries, 17.64% were published in middle-income countries, and only 0.08% were published in low-income countries. Authors in the United States published the most articles (27.38%), followed by China (7.22%), Italy (5.70%), the United Kingdom (5.6%), and Japan (5.54%). Articles published by authors in the United States had the most citations (260,934). A positive correlation was found between the number of publications and population/gross domestic product (GDP; p endocrinology and metabolism articles were published by authors from high-income countries with few from low-income countries. The United States was the most productive country. However, when population size and GDP were considered, some European countries were ranked higher.

Background: The details about the research productivity in the specialty of endocrinology from India is lacking. We plan to assess the publishing trends and the research productivity of Endocrinology related research articles published in the Journal of the Association of Physicians of India (JAPI). Materials and Methods: We carried the bibliometric analysis of endocrinology related articles from JAPI. The data were obtained from the JAPI website for the publications between 2000 and 2011. The articles were analyzed for the type (original article, case reports, correspondence, and pictorial image), subspecialty (diabetes, thyroid, etc.), and place of the research. Data were presented with descriptive statistics in numbers and percentages. Results: Out of a total 2977 articles published by JAPI, 312 articles belong to endocrine subspecialty. Endocrinology related articles constitute about 11.2%–23.2% of the published articles per year in JAPI and the percentage is increasing every year. Original articles (52%) and case reports (27%) constituite the majority, while the rest were letters to editor (9%) and pictorial images (12%). Diabetes (57%) and metabolic bone disorders (16%) lead the subspecialty articles, followed by thyroid (9%), adrenal and gonad (8%), and pituitary (8%). Chennai (20%), Mumbai (14%), and Delhi (9%) are the top 3 places contributing to the articles followed by Chandigarh and Varanasi. Conclusion: Majority of endocrinology related research productivity is seen in form of original articles and case reports. Diabetes is the leading disease with maximum research articles from Chennai and other glands are equally represented in the research productivity. PMID:23226637

The use of noninvasive and minimally invasive methods in endocrinology for threatened mammalian species conservation.

Science.gov (United States)

Kersey, David C; Dehnhard, Martin

2014-07-01

Endocrinology is an indispensable tool in threatened species research. The study of endocrinology in threatened species not only advances knowledge of endocrine mechanism but also contributes to conservation efforts of studied species. To this end, endocrinology has been traditionally used to understand reproductive and adrenocortical endocrine axes by quantifying excreted steroid metabolites. From these studies a large body of knowledge was created that contributed to the field of endocrinology, aided conservation efforts, and created a template by which to validate and conduct this research for other species. In this regard noninvasive hormone monitoring has become a favored approach to study the basic endocrinology of wildlife species. Due to the increased understanding of endocrine physiology of threatened species, breeding rates of captive population have improved to levels allowing for reintroduction of species to restored natural ecosystems. Although these approaches are still employed, advances in biochemical, molecular, and genomic technologies are providing inroads to describe lesser known endocrine activity in threatened species. These new avenues of research will allow for growth of the field with greater depth and breadth. However, for all approaches to endocrinology, limitations on resources and access to animals will require innovation of current methodologies to permit broad application for use in threatened species research.

On September 2016, the Board of the College of Endocrinology and Nutrition of the Portuguese Medical Association carried out a national survey, about all Endocrinology, Diabetes and Metabolism Departments of the public hospitals included in the Portuguese National Health Service and a simplified version of this survey was sent to all endocrinologists working in Portugal and registered with the Portuguese Medical Association. Data related to organizational and human resources were collected, reporting the situation by the end of year 2015. The census registered 107 individuals and 27 Departments. The ratio of endocrinologists-population was 1.4, much lower than in the other European countries (varies between 2 to 4), resulting in alarming shortages of services in some areas of Portugal and in worse quality indicators. These data suggest that actions should be taken to increase the number of endocrinologists and departments in the country. In recent years, the number of residents has significantly increased, which will make it possible to correct this situation.

Obesity, is a chronic, biological, preventable, and treatable disease. The accumulation of fat mass causes physical changes (adiposity), metabolic and hormonal changes due to adipose tissue dysfunction (adiposopathy), and psychological changes. Bariatric endocrinology was conceived from the need to address the neuro-endocrinological derangements that are associated with adiposopathy, and from the need to broaden the scope of the management of its complications. In addition to the well-established metabolic complications of overweight and obesity, adiposopathy leads to hyperinsulinemia, hyperleptinemia, hypoadiponectinemia, dysregulation of gut peptides including GLP-1 and ghrelin, the development of an inflammatory milieu, and the strong risk of vascular disease. Therapy for adiposopathy hinges on effectively lowering the ratio of orexigenic to anorexigenic signals reaching the the hypothalamus and other relevant brain regions, favoring a lower caloric intake. Adiposopathy, overweight and obesity should be treated indefinitely with the specific aims to reduce fat mass for the adiposity complications, and to normalize adipose tissue function for the adiposopathic complications. This paper defines the principles of medical practice in bariatric endocrinology—the treatment of overweight and obesity as means to treat adiposopathy and its accompanying metabolic and hormonal derangements.

1982-01-01

The discovery of regulatory peptides common to the nervous and the endocrine systems (brain, gut, and skin) has brought about a revolution in our concepts of endocrinology and neurology. We are beginning to understand some of the complex interrelationships between soma and psyche that might, someday, be important for an integrated treatment of diseases. Examples of the actions of certain peptides in the periphery and in the central nervous system are given, and their biosynthesis and molecular anatomy as carriers for information are discussed.

Gastrointestinal Hormones Induced the Birth of Endocrinology.

Science.gov (United States)

Wabitsch, Martin

2017-01-01

The physiological studies by British physiologists William Maddock Bayliss and Ernest Henry Starling, at the beginning of the last century, demonstrated the existence of specific messenger molecules (hormones) circulating in the blood that regulate the organ function and physiological mechanisms. These findings led to the concept of endocrinology. The first 2 hormones were secretin, discovered in 1902, and gastrin, discovered in 1905. Both hormones that have been described are produced in the gut. This chapter summarizes the history around the discovery of these 2 hormones, which is perceived as the birth of endocrinology. It is noteworthy that after the discovery of these 2 gastrointestinal hormones, many other hormones were detected outside the gut, and thereafter gut hormones faded from both the clinical and scientific spotlight. Only recently, the clinical importance of the gut as the body's largest endocrine organ producing a large variety of hormones has been realized. Gastrointestinal hormones are essential regulators of metabolism, growth, development and behavior and are therefore the focus of a modern pediatric endocrinologist. © 2017 S. Karger AG, Basel.

Despite the importance of lifestyle change in disease management and the growing evidence supporting motivational interviewing (MI) as an effective counseling method to promote behavioral change, to date there are few published reports about MI training in graduate medical education. The study aimed to pilot the feasibility and effectiveness of a brief MI training intervention for endocrinology fellows and other providers. We used a pretest/posttest design to evaluate a brief MI training for 5 endocrinology fellows and 9 other providers. All participants completed subjective assessments of perceived confidence and beliefs about behavioral counseling at pretest and posttest. Objective assessment of MI was conducted using fellows' audiotaped patient encounters, which were coded using a validated tool for adherence to MI before and after the training. Paired t tests examined changes in objective and subjective assessments. The training intervention was well received and feasible in the endocrinology setting. At posttest, participants reported increased endorsement of the MI spirit and improved confidence in MI skills. Objective assessment revealed relative improvements in MI skills across several domains. However, most domains, as assessed by a validated tool, did not reach competency level after the training intervention. Although more intensive training may be needed to develop MI competence, the results of our pilot study suggest that brief, targeted MI training has short-term efficacy and is well received by endocrinology fellows and other providers.

Science.gov (United States)

Higham, James P

2016-08-01

In the past few decades, research on nonhuman primate endocrinology has moved from the lab to the field, leading to a huge increase in both the breadth and depth of primate field studies. Here, I discuss the past, present, and future of primate field endocrinology. I review the history of the field, and go on to discuss methodological developments and the issues that they sometimes entail. Next, I consider ways in which we might conceptualize the role of hormones, and focus on the need to distinguish proximate from ultimate levels of explanation. Current potentially problematic issues in the field include: 1) an inability to obtain noninvasive measurements of Central Nervous System (CNS) rather than peripheral hormone concentrations; 2) research questions that become stuck (e.g., questions regarding sexual swelling expression mechanisms); 3) data dredging and post-hoc linking of hormones to any plausible variable, leading to a lack of clarity on their role in animal ecology and behavior. I finish by discussing several unanswered questions that might benefit from further research. These are how we might: 1) best obtain measurements for CNS hormone concentrations non-invasively; 2) measure hormone receptor expression alongside hormone concentrations; 3) consider the human endocrinology literature more thoroughly and perhaps take more multimarker approaches; 4) better consider the social environment, including audience and dyadic familiarity effects; and 5) apply our findings to conservation issues.

2017-03-01

Full Text Available Background. Special linguistic researches of terminological units of different branches of medicine allow analyzing in details the ways of creating the systems of clinical terminology from different aspects: historical, scientific, cultural, linguistic and semantic. There is a wide area of terminology related to the clinical and experimental endocrino­logy within general medical terminological system. The purpose of the study: to demonstrate the structure of endocrine medical terms — eponyms through the prism of systematization of methodological researches on eponymic vocabulary. Materials and methods. The actual material received as a result of a total choice of eponyms (there were 296 terms from the “Reference dictionary for endocrinologist”, which was composed by the scientists of V. Danilevsky Institute of Endocrine Pathology Problems and Kharkiv Medical Academy of Postgraduate education — A.V. Kozakov, N.A. Kravchun, I.M. Ilyina, M.I. Zubko, O.A. Goncharova, I.V. Cherniavska has 10,000 endocrine terms, the authors successfully streamlined medical terms of the clinical and experimental endocrinology into the vocabulary. The method of total choice of terms from professional literature, the descriptive method and distributive method were used in the study that allowed distinguishing lexical and semantic features of eponymic terms in the branch of endocrinology. Results. The obtained results point out to the modernity of studies in the field of clinical and experimental endocrinology, which is due to the fact that this is the oldest terminology, by the example of which it is possible to trace the ways of formation, development and improvement of terms, the realization of semantic processes, certain trends, ways and means of word formation. Conclusions. The results of the research on the above mentioned sublanguage of clinical medicine at the level of linguistic observations of the functio­ning in dictionaries and scientific works will

Rates of diabetes for veterans who receive health care through the Veterans Health Administration are higher than rates in the general population. Furthermore, many veterans live in rural locations, far from Veterans Affairs (VA) hospitals, thus limiting their ability to readily seek face-to-face endocrinology care for diabetes. Telehealth (TH) technologies present an opportunity to improve access to specialty diabetes care for such patients; however, there is a lack of evidence regarding the ability of TH to improve glycemic control in comparison to traditional face-to-face consultations. This was a retrospective cohort study of all new endocrinology diabetes consultations at the Denver VA Medical Center over a 1-year period. A total of 189 patients were included in the analysis. In all, 85 patients had received face-to-face (FTF) endocrinology consultation for diabetes and 104 patients had received TH consultation. Subjects were mostly males (94.7%) and the mean age was 62.8 ± 10.1 years old. HbA1c improved from 9.76% (9.40% to 10.11%) to 8.55% (8.20% to 8.91%) (P Endocrinology TH consultations improved short-term glycemic control as effectively as traditional FTF visits in a veteran population with diabetes. © 2016 Diabetes Technology Society.

The European Society of Endocrinology has published this year a series of guidelines for hypoparathyroidism, the management of adrenal incidentalomas as well as for the long-term follow-up of patients operated on for a phaeochromocytoma/paraganglioma (PPGL). For hypoparathyroidism, guidelines insist on screening for chronic complications and monitoring treatment with calcium and vitamin D; the use of recombinant PTH may provide new opportunities for the future. Concerning adrenal incidentalomas, the panel of the guidelines primarily recommends non contrast CT for the evaluation of the risk of malignancy. Patients operated on for a PPGL, should be offered an individualized follow-up plan based on assessment of their risk of tumor recurrence.

Microbial endocrinology: Host-microbiota neuroendocrine interactions influencing brain and behavior.

Science.gov (United States)

Lyte, Mark

2014-01-01

The ability of microorganisms, whether present as commensals within the microbiota or introduced as part of a therapeutic regimen, to influence behavior has been demonstrated by numerous laboratories over the last few years. Our understanding of the mechanisms that are responsible for microbiota-gut-brain interactions is, however, lacking. The complexity of the microbiota is, of course, a contributing factor. Nonetheless, while microbiologists approaching the issue of microbiota-gut-brain interactions in the behavior well recognize such complexity, what is often overlooked is the equal complexity of the host neurophysiological system, especially within the gut which is differentially innervated by the enteric nervous system. As such, in the search for common mechanisms by which the microbiota may influence behavior one may look for mechanisms which are shared by both host and microbiota. Such interkingdom signaling can be found in the shared production of neurochemical mediators that are found in both eukaryotes and prokaryotes. The study of the production and recognition of neurochemicals that are exactly the same in structure to those produced in the vertebrate organisms is known as microbial endocrinology. The examination of the microbiota from the vantage point of host-microbiota neuroendocrine interactions cannot only identify new microbial endocrinology-based mechanisms by which the microbiota can influence host behavior, but also lead to the design of interventions in which the composition of the microbiota may be modulated in order to achieve a specific microbial endocrinology-based profile beneficial to overall host behavior.

Many changes in health care delivery, health legislation, and the physician workforce that affect the supply and demand for endocrinology services have occurred since the first published workforce study of adult endocrinologists in 2003. The objective of the study was to assess the current adult endocrinology workforce data and provide the first analysis of the pediatric endocrinology workforce and to project the supply of and demand for endocrinologists through 2025. A workforce model was developed from an analysis of proprietary and publicly available databases, consultation with a technical expert panel, and the results of an online survey of board-certified endocrinologists. The Endocrine Society commissioned The Lewin Group to estimate current supply and to project gaps between supply and demand for endocrinologists. A technical expert panel of senior endocrinologists provided context, clinical information, and direction. The following were measured: 1) the current adult and pediatric endocrinology workforce and the supply of and demand for endocrinologists through 2025 and 2) the number of additional entrants into the endocrinology work pool that would be required to close the gap between supply and demand. Currently there is a shortage of approximately 1500 adult and 100 pediatric full-time equivalent endocrinologists. The gap for adult endocrinologists will expand to 2700 without an increase in the number of fellows trained. An increase in the prevalence of diabetes mellitus further expands the demand for adult endocrinologists. The gap can be closed in 5 and 10 years by increasing the number of fellowship positions by 14.4% and 5.5% per year, respectively. The gap between supply and demand for pediatric endocrinologists will close by 2016, and thereafter an excess supply over demand will develop at the current rate of new entrants into the work force. There are insufficient adult endocrinologists to satisfy current and future demand. A number of proactive

25 male patients suffering from acne vulgaris were examined by means of endocrinological, morphological, and 5 psychometric procedures in order to check the correlations and interactions between the psychological and dermatological aspects of the disease. In comparison with a control group, the acne patients did not show any striking endocrinological abnormalities; we found no correlation between the extensiveness of the lesions and the level of DHEA sulphate. All the psychological tests yielded results deviating from those achieved by the representative controls, but they were comparable with those of other patients suffering from psychosomatic diseases. The individual feeling of being "disfigured" found its expression in self-consciousness, lack of trust in his/her own body, as well as the clinically relevant difference between his/her conception of self and the ideal of self. During times of enhanced psychosocial strains subjectively assumed by the patients, the lesions increased and the patients were disturbed in social interaction and communication. Surprisingly, we did not find any correlation between the clinical status and significant psychometric findings. Our results show that in acne vulgaris, the individual experience of wanting physical attractiveness, associated with a predominantly neurotic depressive personal structure, may play a central part in a disturbed process of interaction with the environment and suggest the influence of psychic factors in the pathogenesis of acne vulgaris.

Full Text Available Celiac disease is a permanent genetically determined intolerance to gluten that generally presents with gastrointestinal symptoms in young children and extraintestinal manifestations (endocrinological, dermatological, neurological, etc. later. Furthermore, many studies demonstrate the close association between celiac and endocrine diseases, including growth and pubertal disorders, type I diabetes mellitus and autoimmune thyroid diseases, probably due to the presence of a common genetic predisposition. Follow-up for celiac children after the start of gluten-free diet is mandatory to avoid complications such as growth hormone deficiency. The present review deals with the problem of the diagnosis of endocrine-associated diseases in celiac children and gives suggestions for correct management and follow-up of these patients.

With the reference to the position statements of the Endocrine Society, the Paediatric Endocrine Society, and the European Society of Paediatric Endocrinology, the Polish Society of Endocrinology points out the adverse health effects caused by endocrine disrupting chemicals (EDCs) commonly used in daily life as components of plastics, food containers, pharmaceuticals, and cosmetics. The statement is based on the alarming data about the increase of the prevalence of many endocrine disorders such as: cryptorchidism, precocious puberty in girls and boys, and hormone-dependent cancers (endometrium, breast, prostate). In our opinion, it is of human benefit to conduct epidemiological studies that will enable the estimation of the risk factors of exposure to EDCs and the probability of endocrine disorders. Increasing consumerism and the industrial boom has led to severe pollution of the environment with a corresponding negative impact on human health; thus, there is great necessity for the biomonitoring of EDCs in Poland.

The advent of mass spectrometry into the clinical laboratory has led to an improvement in clinical management of several endocrine diseases. Liquid chromatography tandem mass spectrometry found some of its first clinical applications in the diagnosis of inborn errors of metabolism, in quantitative steroid analysis, and in drug analysis laboratories. Mass spectrometry assays offer analytical sensitivity and specificity that is superior to immunoassays for many analytes. This article highlights several areas of clinical endocrinology that have witnessed the use of liquid chromatography tandem mass spectrometry to improve clinical outcomes.

Rare endocrine-metabolic diseases (REMD) represent an important area in the field of medicine and pharmacology. The rare diseases of interest to endocrinologists involve all fields of endocrinology, including rare diseases of the pituitary, thyroid and adrenal glands, paraganglia, ovary and testis, disorders of bone and mineral metabolism, energy and lipid metabolism, water metabolism, and syndromes with possible involvement of multiple endocrine glands, and neuroendocrine tumors. Taking advantage of the constitution of a study group on REMD within the Italian Society of Endocrinology, consisting of basic and clinical scientists, a document on the taxonomy of REMD has been produced. This document has been designed to include mainly REMD manifesting or persisting into adulthood. The taxonomy of REMD of the adult comprises a total of 166 main disorders, 338 including all variants and subtypes, described into 11 tables. This report provides a complete taxonomy to classify REMD of the adult. In the future, the creation of registries of rare endocrine diseases to collect data on cohorts of patients and the development of common and standardized diagnostic and therapeutic pathways for each rare endocrine disease is advisable. This will help planning and performing intervention studies in larger groups of patients to prove the efficacy, effectiveness, and safety of a specific treatment.

Since 1995, the European Society for Paediatric Endocrinology (ESPE) has hosted Winter School (WS), a 5-day interactive meeting of 25 trainees and 7 teachers designed to cover all main endocrine topics. The aim of the present study was to determine subsequent outcome in ex-WS "students." A questionnaire was sent in August 2016 to all ESPE WS participants between 2008 and 2014. Information was requested on job/training status at WS attendance and in 2016, and subsequent involvement with ESPE. Of 174 participants (144 women, 30 men) including 5 attending two WS, 129 (74.5%) responded. At the time of WS/2016 survey 58/3 participants were junior trainees, 38/21 senior trainees, and 33/101 consultants. One hundred and seventeen (90.6%) responders were still involved with endocrinology, 107 (82%) rating WS as having a strong/very strong influence on their careers. Following WS, 80/174 (46%) participants had attended at least one ESPE main meeting, 28 (16%) had been awarded ESPE fellowships, and 34 (19%) had become ESPE members. The great majority of WS participants responding to the questionnaire are still involved with endocrinology and rated WS as influential. This favourable outcome supports the continuing funding of WS and similar educational programmes. © 2017 S. Karger AG, Basel.

Full Text Available Based on educational considerations, the European Society for Paediatric Endocrinology (ESPE e-learning portal has been developed, providing an interactive learning environment for up-to-date information in pediatric endocrinology. From March 2011 to January 2012, five small-scale pilot studies were completed to assess the usefulness of the structure and content by senior experts, fellows, residents and medical students. Altogether, 8 cases and 4 chapters were studied by a total of 71 individuals: 18 senior experts, 21 fellows, 10 medical students, 9 regional pediatricians and 13 residents, resulting in a total of 127 evaluations. Participants considered the portal content interesting and appreciated the way of learning compared to traditional learning from literature and textbooks. Special attention was paid to assess the personalized feedback given by experts to fellows and residents who completed the portal. Feedback from experts included both medical understanding and communication skills demonstrated by fellows and residents. Users highly appreciated the feedback of the medical experts, who brought perspectives from another clinic. This portal also offers educational opportunities for medical students and regional pediatricians and can be used to develop various CanMEDS competencies, e.g., medical expert, health advocate, and scholar.

2015-01-01

This paper presents results of an assessment of the quality research of endocrinology referrals in the public health system in the state of Rio Grande do Sul. From the analysis of 4,458 requests for endocrinology referrals, it was found that 15% of referrals had insufficient information for evaluation and 71% showed no clinical justification for authorization of referencing. The partial results of the study indicated that the lack of information makes it impossible to clinically regulate these requests. The use of referencing protocols associated with telemedicine tools can assist doctors in primary health care in the clinical management and make access to specialized services more equitable and timely.

In medicine and endocrinology, there are few clinical circumstances in which clinicians can accurately predict what is best for their patients. As a result, patients and clinicians frequently have to make decisions about which there is uncertainty. Uncertainty results from limitations in the research evidence, unclear patient preferences, or an inability to predict how treatments will fit into patients' daily lives. The work that patients and clinicians do together to address the patient's situation and engage in a deliberative dialogue about reasonable treatment options is often called shared decision making. Decision aids are evidence-based tools that facilitate this process. Shared decision making is a patient-centred approach in which clinicians share information about the benefits, harms, and burden of different reasonable diagnostic and treatment options, and patients explain what matters to them in view of their particular values, preferences, and personal context. Beyond the ethical argument in support of this approach, decision aids have been shown to improve patients' knowledge about the available options, accuracy of risk estimates, and decisional comfort. Decision aids also promote patient participation in the decision-making process. Despite accumulating evidence from clinical trials, policy support, and expert recommendations in endocrinology practice guidelines, shared decision making is still not routinely implemented in endocrine practice. Additional work is needed to enrich the number of available tools and to implement them in practice workflows. Also, although the evidence from randomised controlled trials favours the use of this shared decision making in other settings, populations, and illnesses, the effect of this approach has been studied in a few endocrine disorders. Future pragmatic trials are needed to explore the effect and feasibility of shared decision making implementation into routine endocrinology and primary care practice. With the

Financial Analysis of Behavioral Health Services in a Pediatric Endocrinology Clinic.

This article addresses a current need in psychological practice by describing a financially feasible model that moves toward integrated care of behavioral health services in a pediatric endocrinology clinic. Financial information (costs and revenue associated with behavioral health services) for the clinic, over an 18-month period (July 2012 to December 2013), was obtained through the hospital's financial department. The clinic meets one half day per week. Over the 18-month period, the behavioral health services generated a net gain of $3661.45 in the favor of the clinic. We determined that the psychologist and clinical psychology residents needed to see a total of four patients per half-day clinic for the clinic to "break-even." We describe one financially feasible way of integrating behavioral health services into a pediatric endocrinology clinic in the hope that this will be generalizable to other medical settings. © The Author 2015.

With recent improvements in the diagnosis and treatment of cancer, the number of childhood cancer survivors (CCSs) has been increasing in Japan. The importance of quality of life during the lifetime of CCSs has now been recognized, and the late effects of cancer treatments are essential and important issues. In this study we analyzed the endocrinological abnormalities of CCSs by retrospectively evaluating 122 outpatients (62 males and 60 females) who had been referred from pediatric oncologists to our follow-up clinic among 151 CCSs attending our hospital more than two years after their cancer treatment. Follow-up duration varied from 2 to 30 (median 8.0) years. Their average age was 17.3 (range 4-36, median 17.0) years, and 38 patients (31.1%) reached adulthood. Endocrinological abnormalities were found in 82 (67%) of 122 survivors. Gonadal dysfunction was observed in 60 patients (49%). Thirty-nine patients (32%) were short or grew at a slower rate. Twenty-six patients (21%) showed thyroid dysfunction. Other abnormalities were as follows: obesity in 20 patients (16%), leanness in 10 (8%), central diabetes insipidus in 11 (9%) and adrenocortical dysfunction in 9 (7%). Low bone mineral density was observed in 41 (42%) of 98 patients evaluated. These endocrinological abnormalities were caused by the combined effects of cancer itself and various treatments (chemotherapy, radiation therapy, surgery, and hematopoietic stem cell transplantation). Lifetime medical surveillance and continuous follow-up are necessary for CCSs, because treatment-related complications may occur during childhood and many years after the therapy as well. Endocrinologists should participate in long-term follow-up of these survivors in collaboration with pediatric oncologists. (author)

This volume contains the Proceedings of the IV European Workshop on Molecular and Cellular Endocrinology of the Testis held in Capri (Italy) between the 9th and 12th April 1986. The workshop was organized in several symposia related to some of the most relevant aspects of the regulation of testicular function. Main topics were the role of cell interactions, the mechanisms of signal transduction, gene expression and metabolic response of somatic cells as well as differentiation of germ cells. One session was devoted to prostaglandins in the male reproductive system and to brief discussions on interstitial fluid and on antispermatogenic compounds. In this book only the main lectures and some selected short papers are presented. (Auth.)

La Facultad de Medicina de la Universidad Javeriana enseñó clínicas durante sus primeros 25 años de existencia en hospitales tradicionales de Bogotá tales como el San José, la Samaritana y el Instituto de Cancerología. La medicina en adultos era manejada por internistas generales como De Zubiría o Carrizosa o por cardiólogos como Consuegra.

Poca cabida había para especialistas, los que con el tiempo empezaron a llegar del exterior. Cuando el Hospital San José se encargaba de la docencia en Medicina Interna, allí se rotaba por el servicio de endocrinología donde se formó como endocrinólogo el doctor Julio Gómez Afanador, quien ha sido casi que el secretario perpetuo de la Sociedad Colombiana de Endocrinología y quien es coautor de muchos de los estudios de bocio endémico y crecimiento producidos por este servicio; en 1965 él organizó una consulta de endocrinología en el Hospital San Ignacio, que a partir de 1968 empecé a dirigir.

La endocrinología se enseñaba poco, que recuerde; hubo clases de fisiología endocrina por Hernán Mendoza y algunas pocas charlas que sobre el tema nos dio Bernardo Reyes en la Samaritana. Con mi amigo y colega Alvaro Mesa resolvimos indagar en un tema que se había puesto de moda merced a las investigaciones de los inmunólogos ingleses Deborah Doniach y su asociado el doctor Roitt: la autoinmunidad tiroidea.

El Instituto de Cancerología nos pareció el sitio adecuado para trabajar en este proyecto que serviría para nuestra tesis de grado pues convocamos el grupo liderado por Jaime Cortázar, quien contaba con Efraím Otero como su asociado y a Jaime Ahumada como residente. Ellos habían sido pioneros en el manejo de los isótopos radioactivos en Colombia y el hecho de que aplicaran una novedosa e impactante tecnología, la gamagrafía en el diagnóstico tiroideo, les daba una aureola de científicos que sin duda nos atrajo.

Full Text Available Objective: Survival rates for childhood acute lymphoblastic leukemia (ALL have significantly improved and late effects of therapy have been important in the follow-up of survivors. The objective of this study is to identify the endocrinological and cardiological late effects of ALL patients treated in our pediatric hematology unit. Materials and Methods: Patients treated for ALL with BFM protocols after at least 5 years of diagnosis and not relapsed were included in the study. Endocrinological late effects (growth failure, obesity, insulin resistance, dyslipidemia, thyroid gland disorders, osteopenia/osteoporosis, and pubertal disorders and cardiological late effects were evaluated. The study group was evaluated with anthropometric measurements, body mass index, and laboratory testing of fasting glucose, insulin, serum lipids, thyroid functions, and bone mineral densities. Echocardiography and pulsed wave Doppler imaging were performed for analysis of cardiac functions. Results: Of the 38 ALL survivors, at least 1 adverse event occurred in 23 (60%, with 8 of them (21% having multiple problems. Six (16% of the survivors were obese and 8 (21% of them were overweight. Subjects who were overweight or obese at the time of diagnosis were more likely to be overweight or obese at last follow-up. Obesity was more frequently determined in patients who were younger than 6 years of age at the time of diagnosis. Insulin resistance was observed in 8 (21% subjects. Insulin resistance was more frequently seen in subjects who had family history of type 2 diabetes mellitus. Hyperlipidemia was detected in 8 (21% patients. Hypothyroidism or premature thelarche were detected in 2 children. Two survivors had osteopenia. Cardiovascular abnormalities occurred in one of the subjects with hypertension and cardiac diastolic dysfunction. Conclusion: We point out the necessity of follow-up of these patients for endocrinological and cardiological late effects, since at least

Thyroid nodule detection has increased with widespread use of ultrasound, which is currently the main tool for detection, monitoring, diagnosis and, in some instances, treatment of thyroid nodules. Knowledge of ultrasound and adequate instruction on its use require a position statement by the scientific societies concerned. The working groups on thyroid cancer and ultrasound techniques of the Spanish Society of Endocrinology and Nutrition have promoted this document, based on a thorough analysis of the current literature, the results of multicenter studies and expert consensus, in order to set the requirements for the best use of ultrasound in clinical practice. The objectives include the adequate framework for use of thyroid ultrasound, the technical and legal requirements, the clinical situations in which it is recommended, the levels of knowledge and learning processes, the associated responsibility, and the establishment of a standardized reporting of results and integration into hospital information systems and endocrinology units.

Outpatient specialty consultations rely on the timeliness and completeness of referral information to facilitate a valuable patient-specialist interaction. This project aimed to increase essential diagnostic information availability at the initial consultation for patients referred for common endocrine conditions frequently lacking such data-diabetes mellitus, thyroid nodule, thyrotoxicosis, and hypercalcemia. At an endocrinology clinic at an academic medical center in rural New England, providers see several thousand new patients annually, the majority of whom are referred by providers external to the clinic's healthcare system. Through consensus, endocrinology clinic providers agreed on the two or three data elements essential for a meaningful initial consultation for each. A quality improvement team employed a planned series of interventions based on previously published methods and an innovative approach: dissemination of a referral guideline, an assessment of referral adequacy in the endocrinology clinic workflow, coupled with focused requests for missing items, and a pre-visit lab appointment. Between April 2015 and March 2016, 762 referrals were reviewed. At baseline for the four conditions, referrals contained all essential elements only 27.5% (22 of 80) of the time. Over a 7-month period, the team implemented the interventions, with subsequent referrals containing all essential elements increasing to 75.5% (P<.0001), largely attributable to the pre-visit lab appointment. Incoming referrals that lack essential information are a significant problem in specialty care and may adversely affect patient experience, provider satisfaction, and clinic efficiency. Improvement may require innovative approaches, such as the potentially transferable and generalizable ones employed here.

Rejuvenation was a chapter of critical importance for the worldwide development of endocrinology in the 1920s. This work explores the acceptance of these techniques in Chile. Starting in the late 19th century, the Chilean Medical Journal (Revista Médica de Chile) incorporated references to experiments with endocrine gland preparations that were being conducted in Europe at the time. An appropriation of the experiments by the Austrian Eugen Steinach began in 1920, with prominent figures such as the Italian professor Juan Noe Crevani and the young Chilean student Ottmar Wilhelm. Between 1922 and 1924, Wilhelm developed a series of experiments on dogs, bulls, pigs, rats and Welfare Board patients through the so-called Steinach operation, which consisted of the sectioning of the efferent channel in one of the testicles. Professor Noe's scientific patronage policy and Wilhelm's strategy of succession in the field led the latter to hold a chair in the new School of Medicine of Universidad de Concepci6n at the age of 25. From this position, the. figure of Wilhelm was fundamental for the development of a line of endocrinological research that was able to position Universidad de Concepci6n as a scientific development centre, which was strengthened by the arrival of another disciple of Steinach in Chile, the Latvian professor Alejandro Lipschütz.

Systematic reviews provide clinicians and policymakers estimates of diagnostic test accuracy and their usefulness in clinical practice. We identified all available systematic reviews of diagnosis in endocrinology, summarized the diagnostic accuracy of the tests included, and assessed the credibility and clinical usefulness of the methods and reporting. We searched Ovid MEDLINE, EMBASE, and Cochrane CENTRAL from inception to December 2015 for systematic reviews and meta-analyses reporting accuracy measures of diagnostic tests in endocrinology. Experienced reviewers independently screened for eligible studies and collected data. We summarized the results, methods, and reporting of the reviews. We performed subgroup analyses to categorize diagnostic tests as most useful based on their accuracy. We identified 84 systematic reviews; half of the tests included were classified as helpful when positive, one-fourth as helpful when negative. Most authors adequately reported how studies were identified and selected and how their trustworthiness (risk of bias) was judged. Only one in three reviews, however, reported an overall judgment about trustworthiness and one in five reported using adequate meta-analytic methods. One in four reported contacting authors for further information and about half included only patients with diagnostic uncertainty. Up to half of the diagnostic endocrine tests in which the likelihood ratio was calculated or provided are likely to be helpful in practice when positive as are one-quarter when negative. Most diagnostic systematic reviews in endocrine lack methodological rigor, protection against bias, and offer limited credibility. Substantial efforts, therefore, seem necessary to improve the quality of diagnostic systematic reviews in endocrinology.

Gregorio Maranon born and dead in Madrid (1887-1960), was a Spanish physician, scientist, historian, philosopher, humanist, and writer, considered one of the most brilliant Spanish intellectuals of the 20th century. He was also a Republican and fought the Primo de Rivera dictatorship, though later expressed his disagreement with communism. Maranon participated closely with the process of exile of Alfonso XIII. From a very early age he learned several foreign languages and was an avid reader, hence he became in contact with the intellectual circles of the time and cultivated a close friendship with Perez Galdos, Menendez-Pelayo, Ortega y Gasset, Pio Baroja, Unamuno, Lerroux among several outstanding and eminent figures of the famous Generation of 14. In Medical School he had great teachers such as Santiago Ramon y Cajal, and later he specialized in endocrinology and became professor of the specialty in the Complutense University in Madrid, moreover he founded the Institute of Medical Pathology and the Department of Experimental Endocrinology, henceforth he contributed to establish the relationship between endocrinology and psychology. At the beginning of the instauration of the Republic, Maranon became a member of the constituent assembly and the parliament, but soon became disillusioned of communism and left Spain before the initiation of the Civil War, remaining in France until 1942 when he returned to Spain to reestablish his private practice, and soon the medical teaching at the hospital which now bears his name. Late work about history, poetry was elaborated at his Toledo Cigarral de Menores.

To identify and rate reproductive endocrinology and infertility (REI) mobile applications (apps) targeted toward REI providers. A list of REI apps was found in both the Apple iTunes and Google Play stores using the following seven MeSH terms: reproductive endocrinology, REI, infertility, fertility, In Vitro Fertilization, IVF, and embryology. Patient-centered apps were excluded. The remaining apps were then evaluated for accuracy using reliable references. Mobile technology. None. Accurate apps were evaluated for comprehensiveness (the extent of the ability to aid in clinical decision-making) and rated with objective and subjective components using the APPLICATIONS scoring system. Using the seven REI-related MeSH terms, 985 apps and 1,194 apps were identified in the Apple iTunes and Google Play stores, respectively. Of these unique apps, only 20 remained after excluding patient-centered apps. Upon further review for applicability to REI specifically and content accuracy, only seven apps remained. These seven apps were then rated using the APPLICATIONS scoring system. Only 0.32% of 2,179 apps reviewed for this study were useful to REI providers. There is potential for further mobile resource development in the area of REI, given the limited number and varying comprehensiveness and quality of available apps.

To evaluate the presence of extreme findings and fluctuation in effect size in endocrinology. We systematically identified all meta-analyses published in 2014 in the field of endocrinology. Within each meta-analysis, the effect size of the primary binary outcome was compared across studies according to their order of publication. We pooled studies using the DerSimonian and Laird random-effects method. Heterogeneity was evaluated using the I(2) and tau(2). Twelve percent of the included 100 meta-analyses reported the largest effect size in the very first published study. The largest effect size occurred in the first 2 earliest studies in 31% of meta-analyses. When the effect size was the largest in the first published study, it was three times larger than the final pooled effect (ratio of rates, 3.26; 95% confidence interval: 1.80, 5.90). The largest heterogeneity measured by I(2) was observed in 18% of the included meta-analyses when combining the first 2 studies or 17% when combing the first 3 studies. In endocrinology, early studies reported extreme findings with large variability. This behavior of the evidence needs to be taken into account when used to formulate clinical policies.

To compare the management of prediabetes between a family practice clinic and internal medicine/endocrinology practice. A randomized, retrospective evaluation of the medical history in 168 eligible patients with a diagnosis of prediabetes or abnormal blood glucose (BG) at a family practice clinic (n = 78) and an internal medicine/endocrinology practice (n = 90). The internal medicine/endocrinology practice provided more counseling regarding lifestyle modifications (91.1% vs 76.9%, P = .039), specific physical activity recommendations (26.7% vs 7.7%, P = .003), and recommended more patients receive 150 minutes/week of moderate exercise (8.9% vs 1.3%, P = .038). The family practice clinic provided more written dietary information (16.9% vs 13.3%, P = .044) and specific weight loss goals (20.5% vs 6.7%, P = .015). The internal medicine/endocrinology practice initiated pharmacological therapy in more patients (51.1% vs 3.8%, P< .001) and had a significant decrease in fasting BG from baseline compared to the family practice clinic (-9.0 vs -5.6 mg/dL, P< .001). Providers are likely to initiate nonpharmacological therapy but may not provide specific education recommended by the American Diabetes Association. The integration of a multidisciplinary team to provide guideline-based nonpharmacologic counseling may be beneficial in improving outcomes in the management of prediabetes. © The Author(s) 2013.

The purpose of this study was to identify whether endocrinologists and primary care physicians (PCP) adequately screen for ophthalmic symptoms/signs within office visits and provide timely ophthalmology referrals in patients with diabetes. Patients between the ages of 18 years and 80 years with diabetes who underwent an office visit with an endocrinologist or a PCP between January 1, 2014, and December 31, 2014, were identified. Demographics, ophthalmic assessments, and referral information were collected. A total of 1,250 patient records were reviewed. Providers asked about ophthalmic symptoms/signs in 95.5% and 71% of endocrinology and primary care office encounters, respectively (P endocrinology and PCP visits, respectively (P < .0001). Ophthalmic complications from diabetes are not adequately screened, especially within the primary care setting, and further quality improvement measures may improve adherence to recommended screening protocols.

The current training program for resident physicians in endocrinology and nutrition (EN) organizes their medical learning. Program evaluation by physicians was assessed using a survey. The survey asked about demographic variables, EN training methods, working time and center, and opinion on training program contents. Fifty-one members of Sociedad Castellano-Manchega de Endocrinología, Nutrición y Diabetes, and Sociedad Andaluza de Endocrinología y Nutrición completed the survey. Forty-percent of them disagreed with the compulsory nature of internal medicine, cardiology, nephrology and, especially, neurology rotations (60%); a majority (>50%) were against several recommended rotations included in the program. The fourth year of residence was considered by 37.8% of respondents as the optimum time for outpatient and inpatient control and monitoring without direct supervision. The recommended monthly number of on-call duties was 3.8±1.2. We detected a positive opinion about extension of residence duration to 4.4±0.5 years. Doctoral thesis development during the residence period was not considered convenient by 66.7% of physicians. Finally, 97.8% of resident physicians would recommend residency in EN to other colleagues. Endocrinologists surveyed disagreed with different training program aspects such as the rotation system, skill acquisition timing, and on-call duties. Therefore, an adaptation of the current training program in EN would be required. Copyright © 2011 SEEN. Published by Elsevier Espana. All rights reserved.

Hormones coordinate developmental, physiological, and behavioral processes within and between all living organisms. They orchestrate and shape organogenesis from early in development, regulate the acquisition, assimilation, and utilization of nutrients to support growth and metabolism, control gamete production and sexual behavior, mediate organismal responses to environmental change, and allow for communication of information between organisms. Genes that code for hormones; the enzymes that synthesize, metabolize, and transport hormones; and hormone receptors are important targets for natural selection, and variation in their expression and function is a major driving force for the evolution of morphology and life history. Hormones coordinate physiology and behavior of populations of organisms, and thus play key roles in determining the structure of populations, communities, and ecosystems. The field of endocrinology is concerned with the study of hormones and their actions. This field is rooted in the comparative study of hormones in diverse species, which has provided the foundation for the modern fields of evolutionary, environmental, and biomedical endocrinology. Comparative endocrinologists work at the cutting edge of the life sciences. They identify new hormones, hormone receptors and mechanisms of hormone action applicable to diverse species, including humans; study the impact of habitat destruction, pollution, and climatic change on populations of organisms; establish novel model systems for studying hormones and their functions; and develop new genetic strains and husbandry practices for efficient production of animal protein. While the model system approach has dominated biomedical research in recent years, and has provided extraordinary insight into many basic cellular and molecular processes, this approach is limited to investigating a small minority of organisms. Animals exhibit tremendous diversity in form and function, life-history strategies, and

To determine the degree of control of cardiovascular risk factors (CVRF) in a sample of patients with diabetes mellitus (DM) attending Endocrinology and Nutrition Departments in Spain. An epidemiological, cross-sectional, multicenter and observational study involving 41 Departments of Endocrinology and Nutrition in Spain. Each department selected patients with DM with over 10 years of evolution, which were treated in outpatient settings. Demographic, anthropometric, clinical and biochemical data, including medication, were collected for each participant. 1159 patients who met the inclusion criteria were recruited. 52% of the participants were patients with type 2 DM. The mean duration of DM was 19.6 years. A proportion of 37%, 44%, 27.6% and 25.5% had good control of their blood pressure (BP), low density cholesterol (LDLc), lipids and glucose, respectively, and only 4.3% did well in all factors evaluated. The percentage of poorly controlled BP was four times higher in type 2 than in type 1 DM. Obesity, low cultural level and aggregation of cardiovascular risk factors were associated with poorer control. The degree of control of CVRF in diabetic patients with long disease duration is insufficient. Copyright © 2010 SEEN. Published by Elsevier Espana. All rights reserved.

Training in reproductive endocrinology (REI) and its male variant, andrology, has been profoundly influenced by the central role captured by assisted reproductive technologies (ART). The marked differences in financial, regulatory, and societal/ethical restrictions on ART in different countries of the world also prominently influence the clinical management of infertility. Training should strive for comprehensive teaching of all medically indicated procedures, even if only to optimize cross-border care. Better international standardization of infertility practices and training would benefit worldwide infertility care and should be promoted by international societies. Copyright © 2015.

A wide use of imaging techniques results in more frequent diagnosis of adrenal incidenataloma. To analyse the current state of knowledge on adrenal incidentaloma in adults in order to prepare practical management recommendations. Following a discussion, the Polish Society of Endocrinology expert working group have analysed the available data and summarised the analysis results in the form of recommendations. Unenhanced adrenal computed tomography (CT) may be recommended as an initial assessment examination helpful in the differentiation between adenomas and "non-adenomatous" lesions. In the case of density > 10 Hounsfield units, CT with contrast medium washout assessment or MRI are recommended. However, in all patients with adrenal incidentaloma, hormonal assessment is recommended in order to exclude pheochromocytoma and hypercortisolism, notwithstanding the clinical picture or concomitant diseases. In addition, examination to exclude primary hyperaldosteronism is suggested in patients with diagnosed hypertension or hypokalaemia. Surgical treatment should be recommended in patients with adrenal incidentaloma, where imaging examinations suggest a malignant lesion (oncological indication) or with confirmed hormonal activity (endocrinological indication). The basis of the surgical treatment is laparoscopic adrenalectomy. Patients with suspected pheochromocytoma must be pharmacologically prepared prior to surgery. In patients not qualified for surgery, control examinations (imaging and laboratory tests) should be established individually, taking into consideration such features as the size, image, and growth dynamics of the tumour, clinical symptoms, hormonal tests results, and concomitant diseases.

Nuclear medicine: Scintiscanning of the kidneys and the renal clearance of radionuclides give us separate information about the function of each kidney. Scintiscanning of the lungs has become very important for the diagnosis of embolisms. Scintiscanning is also an important method for the diagnosis of skeletal diseases (inflamation of neoplasms, especially metastases) or for the diagnosis of introhepatic neoplasms. New nuclear methods evaluating dynamic processes in the cardiovascular system will become of clinical relevance. Endocrinology: A number of radioimmunoassays (especially of thyroxine, triiodthyronine, TSH, ACTH, cortisol, androgeus, estrogeus, progesterone, LH, FSH and prolaction) the isolation and synthesis of hypothalamic releasing hormones, scintiscanning of the thyreoid and the adrenal glands and computed tomography give us information about the endocrine system. In particular, the new radioimmunoassay of prolactin has taught us new aspects of the function of this hormone and the etiology of hyperprolactinemia.

To determine which residency characteristics are associated with performance during endocrinology fellowship training as measured by competency-based faculty evaluation scores and faculty global ratings of trainee performance. We performed a retrospective review of interview applications from endocrinology fellows who graduated from a single academic institution between 2006 and 2013. Performance measures included competency-based faculty evaluation scores and faculty global ratings. The association between applicant characteristics and measures of performance during fellowship was examined by linear regression. The presence of a laudatory comparative statement in the residency program director's letter of recommendation (LoR) or experience as a chief resident was significantly associated with competency-based faculty evaluation scores (β = 0.22, P = .001; and β = 0.24, P = .009, respectively) and faculty global ratings (β = 0.85, P = .006; and β = 0.96, P = .015, respectively). The presence of a laudatory comparative statement in the residency program director's LoR or experience as a chief resident were significantly associated with overall performance during subspecialty fellowship training. Future studies are needed in other cohorts to determine the broader implications of these findings in the application and selection process.

To assess the frequency and the clinical, biochemical, and molecular aspects of familial hypercholesterolemia (FH) in subjects attending an endocrinology unit. An observational, descriptive study evaluating 3,140 subjects attending the endocrinology unit of Centro Médico Orinoco in Ciudad Bolívar, Venezuela, from 7 January 2013 to 9 December 2016. The index cases were selected using the Dutch Lipid Clinic Network criteria. Plasma lipid levels were measured, and a molecular analysis was performed by DNA sequencing of the LDLR and APOB genes. Ten (0.32%) of the 3,140 study patients had clinical and biochemical characteristics consistent with FH. All but one were female. Three had first-degree relatives with prior premature coronary artery; and none had a personal history of this condition. Three patients were obese; three had high blood pressure; and no one suffered from diabetes. Three patients had a history of tendon xanthomas, and one of corneal arcus. LDL-C levels ranged from 191 to 486mg/dL. Two patients were on statin therapy. The genetic causes of FH were identified in four patients, and were LDLR gene mutations in three of them and an APOB gene mutation in exon 26 in the other. Approximately, one out of every 300 people attending this endocrinology unit in those four years had FH, and LDLR gene mutations were the most prevalent cause. Copyright © 2017 SEEN.

Motta-Mena, Natalie V; Puts, David A

2017-05-01

Hormones orchestrate and coordinate human female sexual development, sexuality, and reproduction in relation to three types of phenotypic changes: life history transitions such as puberty and childbirth, responses to contextual factors such as caloric intake and stress, and cyclical patterns such as the ovulatory cycle. Here, we review the endocrinology underlying women's reproductive phenotypes, including sexual orientation and gender identity, mate preferences, competition for mates, sex drive, and maternal behavior. We highlight distinctive aspects of women's sexuality such as the possession of sexual ornaments, relatively cryptic fertile windows, extended sexual behavior across the ovulatory cycle, and a period of midlife reproductive senescence-and we focus on how hormonal mechanisms were shaped by selection to produce adaptive outcomes. We conclude with suggestions for future research to elucidate how hormonal mechanisms subserve women's reproductive phenotypes. Copyright © 2016 Elsevier Inc. All rights reserved.

Postoperative magnetic resonance images of 40 patients after transsphenoidal surgery for pituitary adenoma were evaluated retrospectively. The signal intensities of packing material and residual tumour were analysed. T 1 -weighted spin-echo sequences were obtained in coronal and sagittal views with and without intravenous injection of contrast media. Residual tumour demonstrated homogeneous or inhomogeneous signal intensity on the native scan with homogeneous or inhomogeneous enhancement. Packing material demonstrated a homogeneous signal intensity on the images obtained without injection of contrast media with a peripheral enhancement or alternate layers of low and intermediate signal intensity with alternate enhancement after injection of contrast media. In 5 of 54 examinations different results were found in MRI, endocrinology and surgery (two false negative and one false positive MRI in correlation with endocrinology; two residual tumours on MRI where surgery was supposed to be complete). Application of intravenous contrast media facilitates the interpretation of postoperative examination of the pituitary gland as well as comparison with preoperative examinations and the knowledge of the intraoperative procedure.

Since 2010, the High Authority for health (HAS) recommends the use of non-mydriatic fundus camera for diabetic retinopathy screening. The purpose of this study is to evaluate the results of screening for diabetic retinopathy using the non-mydriatic retinal camera by a physician's assistant in the endocrinology service. This is a retrospective study of all diabetic patients hospitalized in the endocrinology department between May 2013 and November 2013. For each endocrinology patient requiring screening, a previously trained physician's assistant performed fundus photos. The ophthalmologist then provided a written interpretation of the photos on a consultant's sheet. Of the 120 patients screened, 40 (33.3%) patients had uninterpretable photos. Among the 80 interpretable photos, 64 (53.4%) patients had no diabetic retinopathy, and 16 (13.3%) had diabetic retinopathy. No patient had diabetic maculopathy. Specific quality criteria were established by the HAS for screening for diabetic retinopathy using the non-mydriatic retinal camera in order to ensure sufficient sensitivity and specificity. In our study, the two quality criteria were not achieved: the rates of uninterpretable photos and the total number of photos analyzed in a given period. In our center, we discontinued this method of diabetic retinopathy screening due to the high rate of uninterpretable photos. Due to the logistic impossibility of the ophthalmologists taking all the fundus photos, we proposed that the ophthalmic nurses take the photos. They are better trained in the use of the equipment, and can confer directly with an ophthalmologist in questionable cases and to obtain pupil dilation as necessary.

To investigate patients' communication with their gynecologists in the first visit of the gynecological endocrinology outpatient clinics. We developed a questionnaire to evaluate 379 women' expectations of their first visit, information-giving about illness, and understanding of the consultation they encountered from April to August 2010. Descriptive statistics and multiple linear regression analysis were used to analyze the data. Before the first visit, 55% (208/379) of participants hoped to get the doctors' special attention, and 60% (227/379) of patients expected a very satisfying consultation. During the consultation, only 34% (129/379) of patients provided their case history clearly according to physicians' inquiry, 21% (81/379) of patients understood the examination and 28% (105/379) of patients understood the therapeutic regime after doctors' explanation. Correlation analysis showed that sociodemographic characteristics such as young age (under 20 years old), low level of education (primary school or less), and lack of medical knowledge affected patients' information-giving about illness and understanding of their first visit (all ps endocrinology outpatient clinics. They could not communicate well with their doctors, which was affected by age, education, and medical background.

An investigation was carried out to determine reproductive activity of endocrinological and behavior in Akkaraman sheep (n=20.25 years, 74±7.7 body weight) throughout the year in the Middle Anatolian (39 57 deg. N 32.53 deg. W). The onset of estrous was detected by using apron ram for 30-minute period twice a day. Blood samples collected twice a week were analyzed by Enzyme immunoassay for progesterone (p 4 ), by Radio immunoassay for estradiol. Estrus cycle lengths and estrous lengths were (mean±SD) 18.33±1.03 day, 35.16±5.95 hours, respectively. The breeding season lengths were 283±63.36 day and 229.64±63.74 day according to hormonal and behavior data, respectively (P≤0.0032). Frequency of occurrence estrus was high between August and March however the highest peak was in October. The lowest peaks were both in June and July. Plasma progesterone levels were changed between 0.01-9 ng/ml throughout the year and 0.2-0.16 ng/ml in anoestrus. P 4 level of 11-th day of luteal phase of estrus was 3.73±1.50 ng/ml (n=11). Plasma estradiol level was 8.42±2.51 pg/ml between of 1-st and 2-nd day and 3.50±1.50 pg/ml on day 15. Second peak of estradiol determined on day 11 of estrus cycle was 6.09±2.87 pg/ml (n=11)

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) celebrates in 2010 its 60th year as an institute of the National Institutes of Health. NIDDK has been fundamental in providing support for research in endocrinology, fostering research to elucidate basic principles of endocrine signaling leading to understanding of diseases and disorders of hormone action. Over this time span, a move to a more molecular level in understanding of the basis of hormone action has emerged and been supported by NIDDK, with many advances finding their way into a new journal, Molecular Endocrinology. The merging of disciplines that has made this possible constitutes a major force for further progress as NIDDK moves forward over the next 60 yr. Together, NIDDK and Molecular Endocrinology have served as catalysts for advancing knowledge in the field, energizing new paradigms that have led to advances in the clinic. PMID:20660301

PET/CT scans have reached an important place in the evaluation of endocrine tumors. The metabolic marker 18F-FDG is the most widespread over the world, and, for the time being, it is the only one available in our country. The limitations of this technique in Endocrinology include high differentiation and low aggressiveness of most endocrine tumors, and low detection rate for low cellularity and/or small lesions. Indications for PET/CT scan in these tumors should be precise, due to the fact that not all of these lesions are significantly glucose-avid and to extract the maximum diagnostic efficacy of this modality to achieve the optimum diagnostic accuracy. The most important indication is DTC with high Tg levels and negative 131-Iodine scans. It is advisable to indicate a PET/CT scan in patients with Tg > 10 ng/ml and stimulated TSH (endogenous or exogenous). The aim is to locate recurrences and metastases in order to remove them, either surgically or by any other therapy alternative to 131 I. Due to higher uptake in more aggressive lesions, this study has a high prognostic value. In patients with high Tg levels, negative 131 I scan, and abnormal FDG uptake, the practitioner must act more aggressively in order to remove the pathologic foci, while with a negative FDG -PET scan, the conduct can be expectant, with periodic follow-up. The introduction of other positron-emitting tracers like 124-Iodine, is likely to yield superior quality images and provide better diagnoses. FDG has a limited efficiency in neuroendocrine tumors, unless they show a significant level of dedifferentiation. The scan is indicated in MTC, when calcitonin levels are above 1000 pg/ml, in order to locate the tumor sites. With the introduction of more specific positron-emitting radiopharmaceuticals, such as 18F-DOPA, 68Ga DOTA, 11C methomidate, 11C-hydroxytryptophan and others, it will be possible to study the metabolic-molecular behavior of these tumors with a more accurate approach.

The purpose of this study is to evaluate the feasibility and patient acceptability of a novel artificial intelligence (AI)-based diabetic retinopathy (DR) screening model within endocrinology outpatient settings. Adults with diabetes were recruited from two urban endocrinology outpatient clinics and single-field, non-mydriatic fundus photographs were taken and graded for referable DR ( ≥ pre-proliferative DR). Each participant underwent; (1) automated screening model; where a deep learning algorithm (DLA) provided real-time reporting of results; and (2) manual model where retinal images were transferred to a retinal grading centre and manual grading outcomes were distributed to the patient within 2 weeks of assessment. Participants completed a questionnaire on the day of examination and 1-month following assessment to determine overall satisfaction and the preferred model of care. In total, 96 participants were screened for DR and the mean assessment time for automated screening was 6.9 minutes. Ninety-six percent of participants reported that they were either satisfied or very satisfied with the automated screening model and 78% reported that they preferred the automated model over manual. The sensitivity and specificity of the DLA for correct referral was 92.3% and 93.7%, respectively. AI-based DR screening in endocrinology outpatient settings appears to be feasible and well accepted by patients.

The union of microbiology and neurobiology has led to a revolution in the way we view the microbiome. Now recognized as important symbionts, the microorganisms which inhabit multiple niches in mammalian and avian (chicken) hosts, such as the intestinal tract and skin, serve and influence many important physiological functions. The realization that the gut microbiome serves as a kind of "microbial organ" has important implications for many areas of biology. In this paper advances in the field of microbial endocrinology which may hold relevance for the poultry industry are examined. © 2017 Poultry Science Association Inc.

Pheochromocytoma is rare tumor with a highly variable clinical presentation. This report provides clinical picture, efficiency of diagnostics and treatment of pheochromocytoma in 8-years in the endocrinological center in Wroclaw. The records of 37 patients with pheochromocytoma were identified, who were treated in 2000-2007 in the Department of Endocrinology, Diabetology and Isotope Treatment in Wroclaw. There were 23 women (age 23-75 year) and 14 men (age 17-74). We studied frequency of clinical signs, usefulness of diagnostic methods and efficacy of treatment. The duration of the clinical history ranged from 2 months to 16 years. The most frequent symptoms were: hypertension paroxysmal and constant, palpitations, headache, sweating and anxiety. The most sensitive diagnostic method was increased concentration of urinary metanephrine in 24-hour urine. Computed tomography was the most widely used method for tumor localization. Adrenal pheochromocytoma was detecting by CT in all patients, predominated in right adrenal, in 1 case in urinary bladder. Surgery caused remission of hypertension in 59%, improvement in 26.8%, and no changes in 13.9% of patients. Malignancy was reported in 2 cases, 1 woman died after surgery. MEN 2A occur in 21.6%. The diagnosis of pheochromocytma is usually made after long duration of the disease. The study confirms that clinical presentation of pheochromocytoma is variable and nonspecific, this finding makes the diagnosis very difficult. The most typical symptom is paroxysmal hypertension, which is present only in 40%, other symptoms are nonspecific. The measurement of 24-hour urinary metanephrines was the best indicator. CT was almost always successful in localizing the tumor. Patients with pheochromocytoma should be consider for other endocrine diseases especially medullary carcinoma, primary hyperparathyroidism and other component of MEN 2A.

Longitudinal monitoring of patients suggests a causal link between chronic periodontitis and the development of Alzheimer's disease (AD). However, the explanation of how periodontitis can lead to dementia remains unclear. A working hypothesis links extrinsic inflammation as a secondary cause of AD. This hypothesis suggests a compromised oral hygiene leads to a dysbiotic oral microbiome whereby Porphyromonas gingivalis , a keystone periodontal pathogen, with its companion species, orchestrates immune subversion in the host. Brushing and chewing on teeth supported by already injured soft tissues leads to bacteremias. As a result, a persistent systemic inflammatory response develops to periodontal pathogens. The pathogens, and the host's inflammatory response, subsequently lead to the initiation and progression of multiple metabolic and inflammatory co-morbidities, including AD. Insufficient levels of essential micronutrients can lead to microbial dysbiosis through the growth of periodontal pathogens such as demonstrated for P. gingivalis under low hemin bioavailability. An individual's diet also defines the consortium of microbial communities that take up residency in the oral and gastrointestinal (GI) tract microbiomes. Their imbalance can lead to behavioral changes. For example, probiotics enriched in Lactobacillus genus of bacteria, when ingested, exert some anti-inflammatory influence through common host/bacterial neurochemicals, both locally, and through sensory signaling back to the brain. Early life dietary behaviors may cause an imbalance in the host/microbial endocrinology through a dietary intake incompatible with a healthy GI tract microbiome later in life. This imbalance in host/microbial endocrinology may have a lasting impact on mental health. This observation opens up an opportunity to explore the mechanisms, which may underlie the previously detected relationship between diet, oral/GI microbial communities, to anxiety, cognition and sleep patterns

Hypoparathyroidism (HypoPT) is a rare (orphan) endocrine disease with low calcium and inappropriately low (insufficient) circulating parathyroid hormone levels, most often in adults secondary to thyroid surgery. Standard treatment is activated vitamin D analogues and calcium supplementation and not replacement of the lacking hormone, as in other hormonal deficiency states. The purpose of this guideline is to provide clinicians with guidance on the treatment and monitoring of chronic HypoPT in adults who do not have end-stage renal disease. We intend to draft a practical guideline, focusing on operationalized recommendations deemed to be useful in the daily management of patients. This guideline was developed and solely sponsored by The European Society of Endocrinology, supported by CBO (Dutch Institute for Health Care Improvement) and based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE) principles as a methodological base. The clinical question on which the systematic literature search was based and for which available evidence was synthesized was: what is the best treatment for adult patients with chronic HypoPT? This systematic search found 1100 articles, which was reduced to 312 based on title and abstract. The working group assessed these for eligibility in more detail, and 32 full-text articles were assessed. For the final recommendations, other literature was also taken into account. Little evidence is available on how best to treat HypoPT. Data on quality of life and the risk of complications have just started to emerge, and clinical trials on how to optimize therapy are essentially non-existent. Most studies are of limited sample size, hampering firm conclusions. No studies are available relating target calcium levels with clinically relevant endpoints. Hence it is not possible to formulate recommendations based on strict evidence. This guideline is therefore mainly based on how patients are managed in clinical practice

Reproductive technology, especially the diagnosis of pregnancy by radioimmunoassay of fecal steroid metabolites, is an important component of captive propagation, but its role in our understanding of ecological interactions and in situ biological restoration has been more limited. Where large herbivores have been 'released' from predation by the extirpation of carnivores, controversy often exists about possible detrimental effects at the ecosystem level A related concern is that the reestablishment of large carnivores may decrease the availability of prey populations for human subsistence. We suggest that pregnancy assays can be a valuable tool to help distinguish between the roles of predation versus food-imposed limitations on population size and their effects on juvenile recruitment in wild species. We explored this issue through analyses of fecal progestagen concentration (FPC) levels to document pregnancy in moose (Alces alces) in the southern Greater Yellowstone Ecosystem, a site where wolves (Canis lupus) and grizzly bears (Ursus arctos) are recolonizing former habitats after an absence of more than 60 years. Pregnancy was clearly discernible (mean FPC for pregnant and nonpregnant females, respectively: 10.60 vs. 2.57 ??g/g; p endocrinology can be applied to issues involving reproductive events within an ecological context. They also affirm that noninvasive and generally inexpensive endocrinological procedures will be applicable to understanding interactions between recolonizing predators and prey, an issue that will continue to arise because of global restoration efforts, and to the study of rare ungulates in remote systems where data on reproductive events are difficult to obtain.

Objective: The aim was to formulate practice guidelines for the diagnosis and management of congenital hypothyroidism (CH). Evidence: A systematic literature search was conducted to identify key articles relating to the screening, diagnosis, and management of CH. The evidence-based guidelines were developed with the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system, describing both the strength of recommendations and the quality of evidence. In the absence of sufficient evidence, conclusions were based on expert opinion. Consensus Process: Thirty-two participants drawn from the European Society for Paediatric Endocrinology and five other major scientific societies in the field of pediatric endocrinology were allocated to working groups with assigned topics and specific questions. Each group searched the literature, evaluated the evidence, and developed a draft document. These papers were debated and finalized by each group before presentation to the full assembly for further discussion and agreement. Recommendations: The recommendations include: worldwide neonatal screening, approaches to assess the cause (including genotyping) and the severity of the disorder, the immediate initiation of appropriate L-T4 supplementation and frequent monitoring to ensure dose adjustments to keep thyroid hormone levels in the target ranges, a trial of treatment in patients suspected of transient CH, regular assessments of developmental and neurosensory functions, consulting health professionals as appropriate, and education about CH. The harmonization of diagnosis, management, and routine health surveillance would not only optimize patient outcomes, but should also facilitate epidemiological studies of the disorder. Individuals with CH require monitoring throughout their lives, particularly during early childhood and pregnancy. PMID:24446653

Among the numerous societal benefits of comparative endocrinology is the application of our collective knowledge of hormone signaling towards the conservation of threatened and endangered species - conservation endocrinology. For several decades endocrinologists have used longitudinal hormone profiles to monitor reproductive status in a multitude of species. Knowledge of reproductive status among individuals has been used to assist in the management of captive and free-ranging populations. More recently, researchers have begun utilizing molecular and cell-based techniques to gain a more complete understanding of hormone signaling in wildlife species, and to identify potential causes of disrupted hormone signaling. In this review we examine various in vitro approaches we have used to compare estrogen receptor binding and activation by endogenous hormones and phytoestrogens in two species of rhinoceros; southern white and greater one-horned. We have found many of these techniques valuable and practical in species where access to research subjects and/or tissues is limited due to their conservation status. From cell-free, competitive binding assays to full-length receptor activation assays; each technique has strengths and weaknesses related to cost, sensitivity, complexity of the protocols, and relevance to in vivo signaling. We then present a novel approach, in which receptor activation assays are performed in primary cell lines derived from the species of interest, to minimize the artifacts of traditional heterologous expression systems. Finally, we speculate on the promise of next generation sequencing and transcriptome profiling as tools for characterizing hormone signaling in threatened and endangered species.

Science.gov (United States)

Grijpink-van den Biggelaar, K; Drop, S L S; Schuwirth, L

2010-01-01

Global accessibility and dissemination of developments in pediatric endocrinology prompted to examine how to develop an educational interactive e-SPE web portal. A systematic approach was used to identify the relevant aspects of accessibility and dissemination. An orientation at the big idea was made, executed by an analysis of the needs of student and teacher pediatric endocrinologists, a definition of the learning objectives, a research in educational literature and an exploration of ICT design specifications. The intensive collaboration between medical, educational and information technology disciplines resulted in a portal design. The portal meets requirements of adult learning, stresses interaction between partners in learning and offers direct feedback during the learning process. The portal supports the development of not only knowledge but also competences both at junior and advanced levels. When the e-SPE portal is completed, the options for summative assessment will be examined as a medium for international certification in conjunction with local and national requirements (http://espe.elearning.nl).

No conclusive data exist on the value of a high resolution thyroid nodule clinic for management of nodular thyroid disease. The aim of this study was to evaluate the economic impact of and user satisfaction with a high resolution thyroid nodule clinic (HRTNC) in coordination with primary care. A prospective, observational, descriptive study was conducted to analyze data from 3,726 patients (mean age 61±12 years; 85% women) evaluated at an HRTNC during 2014 and 2015. Demographic data (sex and age), number of ultrasound examinations and fine needle aspiration cytologies (FNAC), referral center and consultation type were assessed. In 2014 and 2015, 3,726 neck ultrasound examinations and 926 FNACs (3.8% rated as non-diagnostic) were performed. Among the 1,227 patients evaluated for the first time, 21.5% did not require a second endocrine appointment, which resulted in mean estimated savings of 14,354.55 euros. Of all patients, 41.1% were referred from primary care, 33.4% from endocrinology, and 26.5% from other specialties. As compared to 2013, the number of thyroid ultrasound examinations requested decreased by 65.3% and 59.7% in 2014 and 2015 respectively, with mean estimated savings of 137,563.92 euros. Mean user satisfaction assessed was 4.0 points (95% confidence interval, 3.7-4.3) on a 5-point scale. HRTNCs at endocrinology departments, coordinated with primary care, are a viable, cost-effective alternative with a positive user perception. Copyright © 2016 SEEN.

The aim of this study was to assess the levels of serum lipid and awareness, treatment, and control of dyslipidemia in type 2 diabetes mellitus (T2DM) patients from top-ranked endocrinology clinics in large cities of China. A cross-sectional study in a representative sample of 4807 Chinese adults 40 to 75 years of age was conducted during 2010 to 2011 at 20 endocrinology clinics in top-ranked hospitals covering most of the major cities of China. Serum lipid levels were measured, and treatment of dyslipidemia was recorded and assessed. In the present study, the prevalence of dyslipidemia was 67.1% in T2DM subjects. Among those with dyslipidemia, the proportion of awareness and treatment was 68.7% and 55.9%. Among participants with lipid-lowering therapy, 686 subjects achieved the low-density lipoprotein cholesterol (LDL-C) control less than 2.60 mmol/L, with the rate being 39.4%. In those patients with previous cardiovascular disease, the percentage of participants who achieved LDL-C goal (1.80 mmol/L) was 15.3%. The prevalence of dyslipidemia is high, and the awareness, treatment, and control of dyslipidemia are relatively low in Chinese T2DM patients. This calls for the awareness and intervention of dyslipidemia in these patients. Copyright © 2016 National Lipid Association. Published by Elsevier Inc. All rights reserved.

To conduct a literature review on the diagnosis and management of primary hyperparathyroidism including the classical hipercalcemic form as well as the normocalcemic variant. This scientific statement was generated by a request from the Brazilian Medical Association (AMB) to the Brazilian Society for Endocrinology as part of its Clinical Practice Guidelines program. Articles were identified by searching in PubMed and Cochrane databases as well as abstracts presented at the Endocrine Society, Brazilian Society for Endocrinology Annual Meetings and the American Society for Bone and Mineral Research Annual Meeting during the last 5 years. Grading quality of evidence and strength of recommendation were adapted from the first report of the Oxford Centre for Evidence-based Medicine. All grades of recommendation, including "D", are based on scientific evidence. The differences between A, B, C and D, are due exclusively to the methods employed in generating evidence. We present a scientific statement on primary hyperparathyroidism providing the level of evidence and the degree of recommendation regarding causes, clinical presentation as well as surgical and medical treatment.

Demonstrating competence in clinical skills is key to course completion for medical students. Methods of providing clinical instruction that foster immediate learning and potentially serve as longer-term repositories for on-demand revision, such as online videos demonstrating competent performance of clinical skills, are increasingly being used. However, their impact on learning has been little studied. The aim of this study was to determine the value of adjunctive on-demand video-based training for clinical skills acquisition by medical students in endocrinology. Following an endocrinology clinical tutorial program, 2nd year medical students in the pre-assessment revision period were recruited and randomized to either a set of bespoke on-line clinical skills training videos (TV), or to revision as usual (RAU). The skills demonstrated on video were history taking in diabetes mellitus (DMH), examination for diabetes lower limb complications (LLE), and examination for signs of thyroid disease (TE). Students were assessed on these clinical skills in an observed structured clinical examination two weeks after randomization. Assessors were blinded to student randomization status. For both diabetes related clinical skills assessment tasks, students in the TV group performed significantly better than those in the RAU group. There were no between group differences in thyroid examination performance. For the LLE, 91.7% (n = 11/12) of students randomized to the video were rated globally as competent at the skill compared with 40% (n = 4/10) of students not randomized to the video (p = 0.024). For the DMH, 83.3% (n = 10/12) of students randomized to the video were rated globally as competent at the skill compared with 20% (n = 2/10) of students not randomized to the video (p = 0.007). Exposure to high quality videos demonstrating clinical skills can significantly improve medical student skill performance in an observed structured clinical examination of these skills, when

The combination of the efficient steroid-separating properties of a lipophilic Sephadex derivative Lipidex-5000sup(TM) and the use of antibodies with carefully selected specificity allows the quantitative determination of pregnenolone, progesterone, 17α-hydroxyprogesterone, androstenedione, testosterone, 5α-dihydrotestosterone, 5α-androstanedione, androsterone and 5α-androstane-3α, 17β-diol in 1- to 2-ml samples of both blood serum and amniotic fluid as well as in 300- to 600-mg pieces of prostatic tissue. The adaptation of the pipetting unit and incubator of a discrete clinical chemical analyser, System Olli 3000, for the automation of the radioimmunoassays has resulted in a greatly increased through-put and has decreased the experimental error of the procedure. In studies on reproductive endocrinology, the methodology developed has allowed the detection of a sex difference in androgen composition of the amniotic fluid early in pregnancy. Further, it is very likely that the decline in steroid production by the testis seen during the first year of life and then in senescence is affected by basically different mechanisms. There are also important differences in the steroid content of normal, hyperplastic and carcinomatous prostate. (author)

Forever young: Endocrinology of paedomorphosis in the Mexican axolotl (Ambystoma mexicanum).

De Groef, Bert; Grommen, Sylvia V H; Darras, Veerle M

2018-05-16

The Mexican axolotl (Ambystoma mexicanum) is a salamander species that does not undergo metamorphosis, resulting in the retention of juvenile characteristics in the mature breeding stage (paedomorphosis). Here we review the endocrinological studies investigating the proximate cause of axolotl paedomorphosis with a focus on the hypothalamo-pituitary-thyroid (HPT) axis. It is well established that axolotl paedomorphosis is a consequence of low activity of the HPT axis. The pituitary hormone thyrotropin (TSH) is capable of inducing metamorphosis in the axolotl, which indicates that all processes and interactions in the HPT axis below the pituitary level are functional, but that TSH release is impaired. In metamorphosing species, TSH secretion is largely controlled by the hypothalamic neuropeptide corticotropin-releasing hormone (CRH), which seems to have lost its thyrotropic activity in the axolotl. However, preliminary experiments have not yet confirmed a role for faulty CRH signalling in axolotl paedomorphosis. Other hypothalamic factors and potential pituitary inhibitors need to be investigated to identify their roles in amphibian metamorphosis and axolotl paedomorphosis. Copyright © 2018 Elsevier Inc.

Paediatric endocrinology and diabetes is a paediatric specialty with less common conditions and higher cost medicines. Access to medicines for our specialty in low and middle income countries remains limited. We analysed the content of the WHO (children and adults) and of all available national Model Lists of Essential Medicines (EMLs) for Mexico, the Caribbean, Central and South America from a paediatric endocrinology and diabetes standpoint. A master list of medicines deemed necessary in paediatric endocrinology and diabetes was established and compared with the WHO and national EMLs, taking into account the gross national income. The WHO EMLs, which are largely recognised as an international benchmark and drive the content of the national EMLs, included many but not all medicines present on our master list. Interestingly, several national EMLs from richer countries included medicines that were not present in the WHO EMLs. Our analysis suggests that these medicines could be considered by the WHO for inclusion in their EMLs, which may promote the adoption of more medicines by individual countries. We also propose several changes to the WHO and national EMLs that could facilitate access to medicines in our specialty: age cut-off for a child using physical maturity rather than a set age limit; greater standardisation of the formatting of the national EMLs for easier comparison and collaborations between countries; greater emphasis on age-specificity and population-specificity for some medicines; and formatting of the EMLs in a disease-focused manner rather than as individual medicines.

Comparative endocrinology of aging and longevity regulation

John eAllard

2011-11-01

Full Text Available Hormones regulate growth, development, metabolism, and other complex processes in multicellular animals. For many years it has been suggested that hormones may also influence the rate of the aging process. Aging is a multifactorial process that causes biological systems to break down and cease to function in adult organisms as time passes, eventually leading to death. The exact underlying causes of the aging process remain a topic for debate, and clues that may shed light on these causes are eagerly sought after. In the last two decades, gene mutations that result in delayed aging and extended longevity have been discovered, and many of the affected genes have been components of endocrine signaling pathways. In this review we summarize the current knowledge on the roles of endocrine signaling in the regulation of aging and longevity in various animals. We begin by discussing the notion that conserved systems, including endocrine signaling pathways, regulate the aging process. Findings from the major model organisms: worms, flies and rodents, are then outlined. Unique lessons from studies of non-traditional models: bees, salmon and naked mole rats, are also discussed. Finally, we summarize the endocrinology of aging in humans, including changes in hormone levels with age, and the involvement of hormones in aging-related diseases. The most well studied and widely conserved endocrine pathway that affects aging is the insulin/insulin-like growth factor system. Mutations in genes of this pathway increase the lifespan of worms, flies, and mice. Population genetic evidence also suggests this pathway’s involvement in human aging. Other hormones including steroids have been linked to aging only in a subset of the models studied. Because of the value of comparative studies, it is suggested that the aging field could benefit from adoption of additional model organisms.

Studies on the physiology and endocrinology of reproduction of Helisoma duryi (Mollusca: Pulmonata)

Energy Technology Data Exchange (ETDEWEB)

Miksys, S.L.

1987-01-01

Helisoma duryi is a hermaphroditic, freshwater, pulmonate snail native to North America. It has been proposed as a biological control agent against snail intermediate hosts of Schistosoma sp., a parasitic trematode in man. Very little is known of the physiology and endocrinology of reproduction of H. duryi. This thesis investigates vitello-genesis, endocrine control of the synthesis of albumen, a nutrient-rich fluid catabolized by developing embryos, and the possible endocrine role of the gonad. Light and electron microscopy, chemical extraction, energy dispersive X-ray analysis, and radioimmunoassay are used to identify the yolk protein ferritin. It is proposed that ferritin synthesis, and its circulating levels, are regulated, probably indirectly, by a gonadal factor released into the blood. The rate of synthesis of albumen polysaccharides can be monitored in vitro by providing albumen gland explants with the precursor /sup 14/C-glucose and measuring /sup 14/C-polysaccharide produced. The basal synthetic activity of the gland reflects the reproductive activity of the snail.

Epidemiology of infertility and polycystic ovarian disease: endocrinological and demographic studies.

Science.gov (United States)

Hull, M G

1987-09-01

The frequency of polycystic ovarian disease (PCOD) as a cause of oligo-amenorrhea and infertility was determined, first by characterizing clinically occult PCOD using endocrinological methods, and secondly by estimating the frequency of overt and occult PCOD amongst infertile women residing in a particular area. Four groups of infertile women with oligo-amenorrhea due to 'functional' disorder were compared. The results show that by contrast with the groups having hyperprolactinemia or hypothalamic disorder the group with hirsutism (and therefore presumed PCOD) was closely resembled by a non-hirsute group in terms of estrogenization, LH level, LH/FSH ratio, prolactin level, body mass and responsiveness to clomiphene. The last group was therefore concluded to have a mild occult form of PCOD. The population studies revealed, first, that overt and occult PCOD accounted for 90% of patients with oligomenorrhea and 37% with amenorrhea, or 73% with oligo- or amenorrhea. Oligo- or amenorrhea accounted for 21% of couples with infertility and the annual incidence was 247 patients per million of the general population. The annual incidence of infertility due to PCOD per million was 41 with overt PCOD and 139 with occult PCOD (total 180). Of those, 140 appeared to respond well to clomiphene (78%) but 40 (22%) failed, requiring alternative therapy.

Evolutionary medicine and its implications for endocrinological issues (e.g. menopause).

Science.gov (United States)

Kirchengast, Sylvia; Rühli, Frank

2013-06-01

Evolutionary medicine, which was formalized in the early 1990s, investigates evolutionary causes of recent human disease, disorders and malfunctions but also the influence of changing living conditions and modernization on health and disease. Evolutionary medicine can also provide insights into endocrinological disorders and in particular in the process of female reproductive senescence. Female reproductive senescence, i.e. menopausal transition is physiologically caused by the decline of estrogen secretion, which is associated with various somatic and psychic discomforts making this stage of life extremely uncomfortable. From the viewpoint of evolutionary medicine, these menopausal symptoms are the result from the sudden decrease of very high lifetime estrogen levels to zero during postmenopause, a situation which is quite new in our evolution and history. While women in recent developed countries experience menarche early, menopause late, few pregnancies, short periods of lactation and consequently low life time estrogen levels. The opposite is true of women living in traditional societies, whose living conditions may be interpreted as a mirror of the situation in our history. From this viewpoint we can conclude that menopausal symptoms may are the result of a mismatch between female reproductive physiology and recent living conditions. Copyright © 2013 Elsevier Inc.

Barriers to continuous glucose monitoring (CGM) use continue to hamper adoption of this valuable technology for the management of diabetes. The American Association of Clinical Endocrinologists and the American College of Endocrinology convened a public consensus conference February 20, 2016, to review available CGM data and propose strategies for expanding CGM access. Conference participants agreed that evidence supports the benefits of CGM in type 1 diabetes and that these benefits are likely to apply whenever intensive insulin therapy is used, regardless of diabetes type. CGM is likely to reduce healthcare resource utilization for acute and chronic complications, although real-world analyses are needed to confirm potential cost savings and quality of life improvements. Ongoing technological advances have improved CGM accuracy and usability, but more innovations in human factors, data delivery, reporting, and interpretation are needed to foster expanded use. The development of a standardized data report using similar metrics across all devices would facilitate clinician and patient understanding and utilization of CGM. Expanded CGM coverage by government and private payers is an urgent need. CGM improves glycemic control, reduces hypoglycemia, and may reduce overall costs of diabetes management. Expanding CGM coverage and utilization is likely to improve the health outcomes of people with diabetes.

Reproductive endocrinology and infertility (REI) is one of the original officially recognized subspecialties in obstetrics and gynecology and among the earlier subspecialties in medicine. Recognized by the American Board of Obstetrics and Gynecology in 1972, fellowship programs are now 3 years in length following an obstetrics and gynecology residency. Originally focused on endocrine problems related to reproductive function, the assisted reproductive technologies (ART) have recently become the larger part of training during REI fellowships. It is likely that the subspecialty of REI strengthens the specialty of obstetrics and gynecology and enhances the educational experience of residents in the field. The value of training and certification in REI is most evident in the remarkable and consistent improvement in the success of ART procedures, particularly in vitro fertilization. The requirement for documented research activity during REI fellowships is likely to stimulate a more rapid adoption (translation) of newer research findings into clinical care after training. Although mandatory reporting of outcomes has been proposed as a reason for this improvement the rapid translation of reproductive research into clinical practice is likely to be a major cause. Looking forward, REI training should emphasize and strengthen education and research into the endocrine, environmental, and genetic aspects of female and male reproduction to improve the reproductive health and fertility of all women.

To update previous recommendations developed by the Working Group on Osteoporosis and Mineral Metabolism of the Spanish Society of Endocrinology and Nutrition for the evaluation and treatment of osteoporosis associated to different endocrine and nutritional diseases. Members of the Working Group on Osteoporosis and Mineral Metabolism of the Spanish Society of Endocrinology and Nutrition. Recommendations were formulated according to the GRADE system (Grading of Recommendations, Assessment, Development, and Evaluation) to describe both the strength of recommendations and the quality of evidence. A systematic search was made in MEDLINE (Pubmed) using the following terms associated to the name of each condition: AND "osteoporosis", "fractures", "bone mineral density", and "treatment". Papers in English with publication date between 18 October 2011 and 30 October 2014 were included. The recommendations were discussed and approved by all members of the Working Group. This update summarizes the new data regarding evaluation and treatment of osteoporosis associated to endocrine and nutritional conditions. Copyright © 2015 SEEN. Published by Elsevier España, S.L.U.

MAGEL2 is the paternally expressed gene within Prader-Willi syndrome critical region at 15q11.2. We encountered three individuals in whom truncating mutations of MAGEL2 were identified. Patients 1 and 2, siblings born to healthy, non-consanguineous Japanese parents, showed generalized hypotonia, lethargy, severe respiratory difficulty, poor feeding, and multiple anomalies including arthrogryposis soon after birth. We carried out whole-exome sequencing, which detected a MAGEL2 mutation (c.1912C>T, p.Gln638*, heterozygous). The patients' father was heterozygous for the mutation. Patient 3 was a female infant, showed respiratory difficulty reflecting pulmonary hypoplasia, generalized hypotonia, feeding difficulty and multiple anomalies soon after birth. Targeted next-generation sequencing detected a novel heterozygous mutation in MAGEL2 (c.3131C>A, p.Ser1044*). This mutation was not found in the parents. MAGEL2 mutations, first reported to be the cause of the Prader-Willi like syndrome with autism by Schaaf et al. (2013) Nature Genetics, 45: 1405-1408 show the wide range of phenotypic spectrum from lethal arthrogryposis multiplex congenital to autism spectrum disorder (ASD) and mild intellectual disability (ID). Our results indicate that MAGEL2 mutations cause multiple congenital anomalies and intellectual disability accompanied by arthrogryposis multiplex congenita and various endocrinologic abnormalities, supporting that the view that clinical phenotypes of MAGEL2 mutations are variable. © 2018 Wiley Periodicals, Inc.

flag' clinical features. These 'red flags' comprise findings indicating lack of prior 'mini-puberty' (such as cryptorchidism or micropenis), or the presence of non-reproductive congenital defects known to be associated with specific hypogonadal syndromes, e.g. anosmia, deafness, mirror movements, renal agenesis, dental/digital anomalies, clefting or coloboma would be compatible with Kallmann (or perhaps CHARGE) syndrome. In children, interventions (whether in the form or treatment or simple reassurance) have been historically directed at maximising height potential and minimising psychosocial morbidity, though issues of future fertility and bone density potential are now increasingly 'in the mix'. Apubertal adults almost invariably harbour organic hypogonadism, requiring sensitive acknowledgement of underlying personal issues and the timely introduction of sex hormone replacement therapy at more physiological doses. © 2014 European Society of Endocrinology.

The association of prolonged neonatal jaundice and hypoglycaemia may be secondary to an endocrinological disease. Pituitary insufficiency and primary adrenal insufficiency are the most likely endocrine diseases that need to be ruled out. We retrospectively analysed the clinical and laboratory characteristics of thirteen patients referred to the Hospital de Niños Ricardo Gutiérrez between years 2003 and 2008 due to prolonged neonatal jaundice and hypoglycaemia secondary to pituitary insufficiency in twelve patients, and in one secondary to primary adrenal insufficiency. All patients had a history of neonatal hypoglycaemia. Ten patients had conjugated hyperbilirubinaemia and six also had elevated transaminases. Combined pituitary hormone deficiency was observed in the twelve hypopituitarism patients. Hormonal replacement normalised liver function and resolved the prolonged jaundice in all the patients. None of them underwent liver biopsy. Hypoglycaemia also remitted after hormonal therapy. Prolonged or cholestatic jaundice associated with neonatal hypoglycaemia is highly likely to be due to pituitary hormone deficiency or primary adrenal insufficiency. Early diagnosis and treatment of these children reverts the prolonged jaundice and prevents morbidity and mortality due to recurrent hypoglycaemia and hormone deficiencies.

Santesmases, María Jesús

2006-01-01

A political discourse of peace marked the distribution and use of radioisotopes in biomedical research and in medical diagnosis and therapy in the post-World War II period. This occurred during the era of expansion and strengthening of the United States' influence on the promotion of sciences and technologies in Europe as a collaborative effort, initially encouraged by the policies and budgetary distribution of the Marshall Plan. This article follows the importation of radioisotopes by two Spanish research groups, one in experimental endocrinology and one in molecular biology. For both groups foreign funds were instrumental in the early establishment of their laboratories. The combination of funding and access to previously scarce radioisotopes helped position these groups at the forefront of research in Spain.

Standardized, high-quality training in reproductive endocrinology, infertility, and assisted reproductive technologies (REI-ART) faces challenges owing to the high-tech nature of ART and the important country-to-country differences in clinical practice and regulations overseeing training. Moreover, while the training capacity of the classical by-fellowship training platforms is shrinking, an increasing demand for REI-ART specialists is coming from emerging countries. To meet this expanding need for REI-ART specialists, we propose a novel by-network model linking a reference training center to satellite practical training sites. Simulation should be used more extensively to achieve competency before initiating live clinical experience, analogous to the highly effective training systems that have been used in aviation for decades. Large ART databases that exist because of obligations to report ART activity and results constitute unique yet so far untapped sources for developing by-scenario simulation training models. Online training materials incorporating these state-of-the-art information technology tools could be developed as a means of fulfilling training needs worldwide. Copyright © 2015.

Pituitary adenomas are uncommon, difficult to diagnose tumors whose heterogeneity and low incidence complicate large-scale studies. The Molecular Registry of Pituitary Adenomas (REMAH) was promoted by the Andalusian Society of Endocrinology and Nutrition (SAEN) in 2008 as a cooperative clinical-basic multicenter strategy aimed at improving diagnosis and treatment of pituitary adenomas by combining clinical, pathological, and molecular information. In 2010, the Spanish Society of Endocrinology and Nutrition (SEEN) extended this project to national level and established 6 nodes with common protocols and methods for sample and clinical data collection, molecular analysis, and data recording in a common registry (www.remahnacional.com). The registry combines clinical data with molecular phenotyping of the resected pituitary adenoma using quantitative real-time PCR of expression of 26 genes: Pituitary hormones (GH-PRL-LH-FSH-PRL-ACTH-CGA), receptors (somatostatin, dopamine, GHRH, GnRH, CRH, arginine-vasopressin, ghrelin), other markers (Ki67, PTTG1), and control genes. Until 2015, molecular information has been collected from 704 adenomas, out of 1179 patients registered. This strategy allows for comparative and relational analysis between the molecular profile of the different types of adenoma and the clinical phenotype of patients, which may provide a better understanding of the condition and potentially help in treatment selection. The REMAH is therefore a unique multicenter, interdisciplinary network founded on a shared database that provides a far-reaching translational approach for management of pituitary adenomas, and paves the way for the conduct of combined clinical-basic innovative studies on large patient samples.

We developed clinical practice guidelines to assess the individual risk-benefit profile of androgen replacement therapy in adult male hypogonadism (HG), defined by the presence of specific signs and symptoms and serum testosterone (T) below 12 nmol/L. The task force consisted of eight clinicians experienced in treating HG, selected by the Italian Society of Endocrinology (SIE). The authors received no corporate funding or remuneration. Consensus was guided by a systematic review of controlled trials conducted on men with a mean T treatments for individuals at high risk for complications, such as those with osteoporosis and/or metabolic disorders. We recommend against using TS to improve cardiac outcome and limited mobility. We recommend against using TS in men with prostate cancer, unstable cardiovascular conditions or elevated haematocrit. The task force places a high value on the timely treatment of younger and middle-aged subjects to prevent the long-term consequences of hypoandrogenism.

Captive breeding of whale sharks is one of the great challenges for aquariums. However, there is limited information available related to reproductive physiology due to the difficulty of sampling and long-term observation. In the present report, we provide information on the reproductive physiology of female whale sharks, which were incidentally captured as bycatch in a set-net off the coast of Okinawa, Japan. Total lengths of three captured female whale sharks were 403, 665, and 761 cm, respectively, at the time of their death. Collected paired ovaries differed in size between right and left. However, it seems not to determine which side of ovary becomes developed. Histological observations revealed that oocytes surrounded by follicle cell layers localized in the developed ovary, and most developed oocytes exhibited yolk vesicle stage. Additionally, in the largest specimen, there were low levels of three steroid hormones (Testosterone, Dihydrotestosterone, and Estradiol-17ß) that did not show seasonal variation. The present results indicate that even the whale shark over 7 m in TL are still histologically and endocrinologically immature. We expect that the present data will provide fundamental information related to reproductive physiology of female whale sharks, and will contribute to protection activities and increased success in captive breeding of whale sharks.

MECHANISMS IN ENDOCRINOLOGY: Nutrition as a mediator of oxidative stress in metabolic and reproductive disorders in women.

Nutrition can generate oxidative stress and trigger a cascade of molecular events that can disrupt oxidative and hormonal balance. Nutrient ingestion promotes a major inflammatory and oxidative response at the cellular level in the postprandial state, altering the metabolic state of tissues. A domino of unfavorable metabolic changes is orchestrated in the main metabolic organs, including adipose tissue, skeletal muscle, liver and pancreas, where subclinical inflammation, endothelial dysfunction, mitochondrial deregulation and impaired insulin response and secretion take place. Simultaneously, in reproductive tissues, nutrition-induced oxidative stress can potentially violate delicate oxidative balance that is mandatory to secure normal reproductive function. Taken all the above into account, nutrition and its accompanying postprandial oxidative stress, in the unique context of female hormonal background, can potentially compromise normal metabolic and reproductive functions in women and may act as an active mediator of various metabolic and reproductive disorders. © 2017 European Society of Endocrinology.

Clinical practice guideline (CPG), clinical practice algorithm (CPA), and clinical checklist (CC, collectively CPGAC) development is a high priority of the American Association of Clinical Endocrinologists (AACE) and American College of Endocrinology (ACE). This 2017 update in CPG development consists of (1) a paradigm change wherein first, environmental scans identify important clinical issues and needs, second, CPA construction focuses on these clinical issues and needs, and third, CPG provide CPA node/edge-specific scientific substantiation and appended CC; (2) inclusion of new technical semantic and numerical descriptors for evidence types, subjective factors, and qualifiers; and (3) incorporation of patient-centered care components such as economics and transcultural adaptations, as well as implementation, validation, and evaluation strategies. This third point highlights the dominating factors of personal finances, governmental influences, and third-party payer dictates on CPGAC implementation, which ultimately impact CPGAC development. The AACE/ACE guidelines for the CPGAC program is a successful and ongoing iterative exercise to optimize endocrine care in a changing and challenging healthcare environment.

To understand how the social and physical environment influences behaviour, reproduction and survival, studies of underlying hormonal processes are crucial; in particular, interactions between stress and reproductive responses may have critical influences on breeding schedules. Several authors have examined the timing of breeding in relation to environmental stimuli, while others have independently described endocrine profiles. However, few studies have simultaneously measured endocrine profiles, breeding behaviour, and offspring survival across seasons. We measured sex and stress hormone concentrations (oestrogens, testosterone, and corticosterone), timing of breeding, and chick survival, in Adelie penguins (Pygoscelis adeliae) at two colonies in two different years. Clutch initiation at Cape Bird South (CBS; year 1, ~14,000 pairs) occurred later than at Cape Crozier East (CCE; year 2, ~ 25,000 pairs); however, breeding was more synchronous at CBS. This pattern was probably generated by the persistence of extensive sea ice at CBS (year 1). Higher corticosterone metabolite and lower sex hormone concentrations at CBS correlated with later breeding and lower chick survival compared to at CCE - again, a likely consequence of sea ice conditions. Within colonies, sub-colony size (S, 50-100; M, 200-300; L, 500-600; XL, >1000 pairs) did not influence the onset or synchrony of breeding, chick survival, or hormone concentrations. We showed that the endocrine profiles of breeding Adelie penguins can differ markedly between years and/or colonies, and that combining measures of endocrinology, behaviour, and offspring survival can reveal the mechanisms and consequences that different environmental conditions can have on breeding ecology.

Phaeochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumours. Standard treatment is surgical resection. Following complete resection of the primary tumour, patients with PPGL are at risk of developing new tumoural events. The present guideline aims to propose standardised clinical care of long-term follow-up in patients operated on for a PPGL. The guideline has been developed by The European Society of Endocrinology and based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE) principles. We performed a systematic review of the literature and analysed the European Network for the Study of Adrenal Tumours (ENS@T) database. The risk of new events persisted in the long term and was higher for patients with genetic or syndromic diseases. Follow-up in the published cohorts and in the ENS@T database was neither standardised nor exhaustive, resulting in a risk of follow-up bias and in low statistical power beyond 10 years after complete surgery. To inform patients and care providers in this context of low-quality evidence, the Guideline Working Group therefore prepared recommendations on the basis of expert consensus. Key recommendations are the following: we recommend that all patients with PPGL be considered for genetic testing; we recommend assaying plasma or urinary metanephrines every year to screen for local or metastatic recurrences or new tumours; and we suggest follow-up for at least 10 years in all patients operated on for a PPGL. High-risk patients (young patients and those with a genetic disease, a large tumour and/or a paraganglioma) should be offered lifelong annual follow-up. © 2016 European Society of Endocrinology.

Craniopharyngiomas are locally aggressive tumors which typically are focused in the sellar and suprasellar region near a number of critical neural and vascular structures mediating endocrinologic, behavioral, and visual functions. The present study aims to summarize and compare the published literature regarding morbidity resulting from treatment of craniopharyngioma. We performed a comprehensive search of the published English language literature to identify studies publishing outcome data of patients undergoing surgery for craniopharyngioma. Comparisons of the rates of endocrine, vascular, neurological, and visual complications were performed using Pearson’s chi-squared test, and covariates of interest were fitted into a multivariate logistic regression model. In our data set, 540 patients underwent surgical resection of their tumor. 138 patients received biopsy alone followed by some form of radiotherapy. Mean overall follow-up for all patients in these studies was 54 ± 1.8 months. The overall rate of new endocrinopathy for all patients undergoing surgical resection of their mass was 37% (95% CI = 33–41). Patients receiving GTR had over 2.5 times the rate of developing at least one endocrinopathy compared to patients receiving STR alone or STR + XRT (52 vs. 19 vs. 20%, χ2P < 0.00001). On multivariate analysis, GTR conferred a significant increase in the risk of endocrinopathy compared to STR + XRT (OR = 3.45, 95% CI = 2.05–5.81, P < 0.00001), after controlling for study size and the presence of significant hypothalamic involvement. There was a statistical trend towards worse visual outcomes in patients receiving XRT after STR compared to GTR or STR alone (GTR = 3.5% vs. STR 2.1% vs. STR + XRT 6.4%, P = 0.11). Given the difficulty in obtaining class 1 data regarding the treatment of this tumor, this study can serve as an estimate of expected outcomes for these patients, and guide decision making until these data are available.

ADIPOSITY-BASED CHRONIC DISEASE AS A NEW DIAGNOSTIC TERM: THE AMERICAN ASSOCIATION OF CLINICAL ENDOCRINOLOGISTS AND AMERICAN COLLEGE OF ENDOCRINOLOGY POSITION STATEMENT.

2017-03-01

The American Association of Clinical Endocrinologists (AACE) and American College of Endocrinology (ACE) have created a chronic care model, advanced diagnostic framework, clinical practice guidelines, and clinical practice algorithm for the comprehensive management of obesity. This coordinated effort is not solely based on body mass index as in previous models, but emphasizes a complications-centric approach that primarily determines therapeutic decisions and desired outcomes. Adiposity-Based Chronic Disease (ABCD) is a new diagnostic term for obesity that explicitly identifies a chronic disease, alludes to a precise pathophysiologic basis, and avoids the stigmata and confusion related to the differential use and multiple meanings of the term "obesity." Key elements to further the care of patients using this new ABCD term are: (1) positioning lifestyle medicine in the promotion of overall health, not only as the first algorithmic step, but as the central, pervasive action; (2) standardizing protocols that comprehensively and durably address weight loss and management of adiposity-based complications; (3) approaching patient care through contextualization (e.g., primordial prevention to decrease obesogenic environmental risk factors and transculturalization to adapt evidence-based recommendations for different ethnicities, cultures, and socio-economics); and lastly, (4) developing evidence-based strategies for successful implementation, monitoring, and optimization of patient care over time. This AACE/ACE blueprint extends current work and aspires to meaningfully improve both individual and population health by presenting a new ABCD term for medical diagnostic purposes, use in a complications-centric management and staging strategy, and precise reference to the obesity chronic disease state, divested from counterproductive stigmata and ambiguities found in the general public sphere.

The American Association of Clinical Endocrinologists (AACE) and American College of Endocrinology (ACE) convened their first Workshop for recommendations to optimize Clinical Practice Algorithm (CPA) development for Latin America (LA) in diabetes (focusing on glycemic control), obesity (focusing on weight loss), thyroid (focusing on thyroid nodule diagnostics), and bone (focusing on postmenopausal osteoporosis) on February 28, 2015, in San Jose, Costa Rica. A standardized methodology is presented incorporating various transculturalization factors: resource availability (including imaging equipment and approved pharmaceuticals), health care professional and patient preferences, lifestyle variables, socio-economic parameters, web-based global accessibility, electronic implementation, and need for validation protocols. A standardized CPA template with node-specific recommendations to assist the local transculturalization process is provided. Participants unanimously agreed on the following five overarching principles for LA: (1) there is only one level of optimal endocrine care, (2) hemoglobin A1C should be utilized at every level of diabetes care, (3) nutrition education and increased pharmaceutical options are necessary to optimize the obesity care model, (4) quality neck ultrasound must be part of an optimal thyroid nodule care model, and (5) more scientific evidence is needed on osteoporosis prevalence and cost to justify intervention by governmental health care authorities. This 2015 AACE/ACE Workshop marks the beginning of a structured activity that assists local experts in creating culturally sensitive, evidence-based, and easy-to-implement tools for optimizing endocrine care on a global scale.

To analyze the use of Spanish language translation on the websites of reproductive endocrinology and infertility (REI) practices in the context of evidence of underuse of infertility services by minority populations. Cross-sectional survey of websites from REI practices. Not applicable. None. None. Assessment of the relationship between having a Spanish-translated website and REI practice characteristics. Variables included concurrent use of social media, size of the practice, Spanish-speaking practitioner in the practice, being a private or a university-based practice, being in a mandated insurance state, and being in an area with different levels of percentage of Hispanic population, adjusted for annual income levels of the population. Of the 376 REI practice websites analyzed, 101 (27%) offered at least some information in Spanish. We identified 97 Spanish-speaking practitioners at 71 REI practices. Having a Spanish-translated website was significantly associated with the practice's use of social media, having an international/out-of-town web page, and having a Spanish-speaking physician in the practice. The size of the practice, as measured in number of cycles reported per year, was not associated with having a translated website. In practices located in the top 60 metropolitan areas by Hispanic population, the odds of having a Spanish-translated website were only related to the percentage of Hispanic population after adjusting for state-mandated insurance and average annual income level of the Hispanic population. Sixty-six of the websites with Spanish-translated content had been automatically translated. An additional eight websites were partially translated automatically. REI practices in metropolitan areas with a higher percentage of Hispanics were more likely to reach out to this minority population by translating their website content into Spanish. These practices were also more likely to use social media. Future studies are needed to determine whether

The study was designed to examine pathophysiology of endocrinological disturbance associated with diminished pituitary function by using magnetic resonance (MR) imaging. The subjects were 13 patients with hemorrhagic pituitary adenoma. According to clinical severity, the patients were classified as having (I) classical pituitary apoplexy (PA, n=2), (II) subacute PA (n=4), or (III) asymptomatic hemorrhagic pituitary adenoma (n=7). MR imaging and intraoperative findings revealed hemorrhagic PA in 7 patients and necrotic cyst formation in 5 patients. The cyst contents, either hemorrhagic or xanthochromic, were more accurately predicted by intensities on MR images than CT fidnings. Niveau formation was seen in 2 patients in Group I on MR images; however, MR imaging intensities differed in the two patients. In the first patient who developed classical PA during pregnancy, the upper and lower parts of the pituitary gland were seen as high intensity and iso-intensity, respectively. In the other patient, the upper and lower parts were seen as water-like and methemoglobin-like intensities, respectively. These findings have implications for the different etiology of niveau formation. In conclusion, diminished hypothalamic and pituitary function in pituitary hemorrhage seemed to be associated with disturbance of the connection between hypothalamus-anterior pituitary gland, or stalk of the pituitary gland. Hemorrhagic pituitary apoplexy manifested by various clinical features seemed to be attributed to venous hemorrhagic infarction due to pituitary portal compression. Pituitary apoplexy itself seemed to compress the portal system, leading to venous hemorrhage. (N.K.)

MECHANISMS IN ENDOCRINOLOGY: Neurodevelopmental disorders in children born to mothers with thyroid dysfunction: evidence of fetal programming?

Fetal programming is a long-standing, but still evolving, concept that links exposures during pregnancy to the later development of disease in the offspring. A fetal programming effect has been considered within different endocrine axes and in relation to different maternal endocrine diseases. In this critical review, we describe and discuss the hypothesis of fetal programming by maternal thyroid dysfunction in the context of fetal brain development and neurodevelopmental disorders in the offspring. Thyroid hormones are important regulators of early brain development, and evidence from experimental and observational human studies have demonstrated structural and functional abnormalities in the brain caused by the lack or excess of thyroid hormone during fetal brain development. The hypothesis that such abnormalities introduced during early fetal brain development increase susceptibility for the later onset of neurodevelopmental disorders in the offspring is biologically plausible. However, epidemiological studies on the association between maternal thyroid dysfunction and long-term child outcomes are observational in design, and are challenged by important methodological aspects. © 2017 European Society of Endocrinology.

It has been suggested that vitamin D may play a role in the pathogenesis of several endocrine diseases, such as hyperparathyroidism, type 1 diabetes (T1DM), type 2 diabetes (T2DM), autoimmune thyroid diseases, Addison's disease and polycystic ovary syndrome (PCOS). In this review, we debate the role of vitamin D in the pathogenesis of endocrine diseases. Narrative overview of the literature synthesizing the current evidence retrieved from searches of computerized databases, hand searches and authoritative texts. Evidence from basic science supports a role for vitamin D in many endocrine conditions. In humans, inverse relationships have been reported not only between blood 25-hydroxyvitamin D and parathyroid hormone concentrations but also with risk of T1DM, T2DM, and PCOS. There is less evidence for an association with Addison's disease or autoimmune thyroid disease. Vitamin D supplementation may have a role for prevention of T2DM, but the available evidence is not consistent. Although observational studies support a potential role of vitamin D in endocrine disease, high quality evidence from clinical trials does not exist to establish a place for vitamin D supplementation in optimizing endocrine health. Ongoing randomized controlled trials are expected to provide insights into the efficacy and safety of vitamin D in the management of endocrine disease. © 2014 European Society of Endocrinology.

To identify the current and future state of the practice of reproductive medicine. Cross-sectional survey. Not applicable. None. Not applicable. The survey included 57 questions designed to assess practice patterns/metrics and professional satisfaction and morale. A total of 336/1,100 (31%) responded, and they were 38% women, 61% men, and 76% Caucasian, with a mean age of 54. Respondents averaged 2.3 jobs and averaged 53 hours of work per week: 44% work in academia and 50% in private groups. Average practice size was 5.5, with an average of 470 fresh IVF cycles performed per year. Percent effort included 63% infertility, 10% endocrinology, 10% surgery, and 9% research. Respondents performed an average of 13 major surgeries, 69 minor surgeries, and 128 oocyte retrievals per year. A total of 60% were salaried, and 40% were equity partners. Compensation was highly skewed. Greater than 84% had a positive morale and had a positive view of the future, and 92% would again choose REI as a career. The most satisfying areas of employment were patient interactions, intellectual stimulation, interactions with colleagues, and work schedule. The least satisfying areas were work schedule and financial compensation. Training was felt to be too focused on female factor infertility and basic research with insufficient training on embryology, genetics, male factor infertility, and clinical research. In the next 5 years, 57% suggested that the need for specialists would stay the same, while 20% predicted a decrease. A total of 58% felt we are training the correct number of fellows (37% felt we are training a surplus). Compared with academia, those in private practice reported higher compensation, less major surgery, more IVF, less endocrinology, and less research. Men worked more hours, conducted more surgery and IVF cycles, and had higher compensation than women. Morale was similar across age, gender, practice type, and geography. Our subspecialty has an extremely high morale. We

Obesity and thyroid diseases are common disorders in the general population and they frequently occur in single individuals. Alongside a chance association, a direct relationship between 'thyroid and obesity' has been hypothesized. Thyroid hormone is an important determinant of energy expenditure and contributes to appetite regulation, while hormones and cytokines from the adipose tissue act on the CNS to inform on the quantity of energy stores. A continuous interaction between the thyroid hormone and regulatory mechanisms localized in adipose tissue and brain is important for human body weight control and maintenance of optimal energy balance. Whether obesity has a pathogenic role in thyroid disease remains largely a matter of investigation. This review highlights the complexity in the identification of thyroid hormone deficiency in obese patients. Regardless of the importance of treating subclinical and overt hypothyroidism, at present there is no evidence to recommend pharmacological correction of the isolated hyperthyrotropinemia often encountered in obese patients. While thyroid hormones are not indicated as anti-obesity drugs, preclinical studies suggest that thyromimetic drugs, by targeting selected receptors, might be useful in the treatment of obesity and dyslipidemia. © 2014 European Society of Endocrinology.

Polycystic ovary syndrome (PCOS) is the most common ovarian disorder associated with androgen excess in women, which justifies the growing interest of endocrinologists. Great efforts have been made in the last 2 decades to define the syndrome. The presence of three different definitions for the diagnosis of PCOS reflects the phenotypic heterogeneity of the syndrome. Major criteria are required for the diagnosis, which in turn identifies different phenotypes according to the combination of different criteria. In addition, the relevant impact of metabolic issues, specifically insulin resistance and obesity, on the pathogenesis of PCOS, and the susceptibility to develop earlier than expected glucose intolerance states, including type 2 diabetes, has supported the notion that these aspects should be considered when defining the PCOS phenotype and planning potential therapeutic strategies in an affected subject. This paper offers a critical endocrine and European perspective on the debate on the definition of PCOS and summarises all major aspects related to aetiological factors, including early life events, potentially involved in the development of the disorder. Diagnostic tools of PCOS are also discussed, with emphasis on the laboratory evaluation of androgens and other potential biomarkers of ovarian and metabolic dysfunctions. We have also paid specific attention to the role of obesity, sleep disorders and neuropsychological aspects of PCOS and on the relevant pathogenetic aspects of cardiovascular risk factors. In addition, we have discussed how to target treatment choices based according to the phenotype and individual patient's needs. Finally, we have suggested potential areas of translational and clinical research for the future with specific emphasis on hormonal and metabolic aspects of PCOS. © 2014 European Society of Endocrinology.

Full Text Available Las prácticas de los psicólogos en el campo de la Endocrinología y las de los propios endocrinólogos, requieren un mínimo de conocimientos sobre los efectos conductuales no endocrinos de las hormonas. La temporalidad es un concepto clave en Neurobiología, hecho que puede observarse con claridad en el efecto de las hormonas sobre la conducta, al tratarse de acciones moduladas por el período de maduración del sistema nervioso en que se ejercen. El mecanismo neural que facilita la ocurrencia de estas acciones en el tiempo es la plasticidad cerebral. Las hormonas, en su condición de factores epigenéticos, influyen en la conducta mediante los procesos de plasticidad, y provocan dos efectos principales: el organizador y el activador. El primero se refiere a la capacidad de las hormonas de influir en la citoarquitectura y estructura del cerebro de manera permanente durante el desarrollo, desde el período fetal hasta el final de la adolescencia, aunque algunos estudios sugieren que este efecto se mantiene más allá del período de la pubertad. El activador se relaciona con la activación de células diana para facilitar conductas en contextos específicos. Se trata de influencias transitorias, puntuales, que dependen de la concentración de las hormonas en cada instante. Solo conociendo la compleja relación entre el sustrato neural, las condiciones hormonales y el grado de maduración del sistema nervioso en general, y del cerebro en particular, se pueden diseñar estrategias terapéuticas correctas. El desconocimiento de estas interrelaciones lleva al riesgo de trabajar solo con la subjetividad del paciente y desconocer sus potencialidades y limitaciones.The practice of psychologists in the field of endocrinology and that of the endocrinologists as such require a minimum level of knowledge on the non-endocrine behavioral effects of hormones.

Several experimental and cross-sectional studies have established the stress-buffering effect of social identification, yet few longitudinal studies have been conducted within this area of research. This study is the first to make use of a multilevel approach to disaggregate between- and within-person effects of social identification on subjective and endocrinological stress reactions. Specifically, we conducted a study with 85 prospective students during their 1-day aptitude test for a university sports program. Ad hoc groups were formed, in which students completed several tests in various disciplines together. At four points in time, salivary cortisol, subjective strain, and identification with their group were measured. Results of multilevel analyses show a significant within-person effect of social identification: The more students identified with their group, the less stress they experienced and the lower their cortisol response was. Between-person effects were not significant. Advantages of using multilevel approaches within this field of research are discussed. © 2015 by the Society for Personality and Social Psychology, Inc.

MECHANISMS IN ENDOCRINOLOGY: Aberrations of the X chromosome as cause of male infertility.

Science.gov (United States)

Röpke, Albrecht; Tüttelmann, Frank

2017-11-01

Male infertility is most commonly caused by spermatogenetic failure, clinically noted as oligo- or a-zoospermia. Today, in approximately 20% of azoospermic patients, a causal genetic defect can be identified. The most frequent genetic causes of azoospermia (or severe oligozoospermia) are Klinefelter syndrome (47,XXY), structural chromosomal abnormalities and Y-chromosomal microdeletions. Consistent with Ohno's law, the human X chromosome is the most stable of all the chromosomes, but contrary to Ohno's law, the X chromosome is loaded with regions of acquired, rapidly evolving genes, which are of special interest because they are predominantly expressed in the testis. Therefore, it is not surprising that the X chromosome, considered as the female counterpart of the male-associated Y chromosome, may actually play an essential role in male infertility and sperm production. This is supported by the recent description of a significantly increased copy number variation (CNV) burden on both sex chromosomes in infertile men and point mutations in X-chromosomal genes responsible for male infertility. Thus, the X chromosome seems to be frequently affected in infertile male patients. Four principal X-chromosomal aberrations have been identified so far: (1) aneuploidy of the X chromosome as found in Klinefelter syndrome (47,XXY or mosaicism for additional X chromosomes). (2) Translocations involving the X chromosome, e.g. nonsyndromic 46,XX testicular disorders of sex development (XX-male syndrome) or X-autosome translocations. (3) CNVs affecting the X chromosome. (4) Point mutations disrupting X-chromosomal genes. All these are reviewed herein and assessed concerning their importance for the clinical routine diagnostic workup of the infertile male as well as their potential to shape research on spermatogenic failure in the next years. © 2017 European Society of Endocrinology.

Information sharing in chronic conditions such as disorders of/differences in sex development (DSD) is essential for a comprehensive understanding by parents and patients. We report on a qualitative analysis of communication skills of fellows undergoing training in paediatric endocrinology. Guidelines are created for the assessment of communication between health professionals and individuals with DSD and their parents. Paediatric endocrinology fellows worldwide were invited to study two interactive online cases (www.espe-elearning.org) and to describe a best practice communication with (i) the parents of a newborn with congenital adrenal hyperplasia and (ii) a young woman with 46,XY gonadal dysgenesis. The replies were analysed regarding completeness, quality, and evidence of empathy. Guidelines for structured assessment of responses were developed by 22 senior paediatric endocrinologists worldwide who assessed 10 selected replies. Consensus of assessors was established and the evaluation guidelines were created. The replies of the fellows showed considerable variation in completeness, quality of wording, and evidence of empathy. Many relevant aspects of competent clinical communication were not mentioned; 15% (case 1) and 17% (case 2) of the replies were considered poor/insufficient. There was also marked variation between 17 senior experts in the application of the guidelines to assess communication skills. The guidelines were then adjusted to a 3-level assessment with empathy as a separate key item to better reflect the qualitative differences in the replies and for simplicity of use by evaluators. E-learning can play an important role in assessing communication skills. A practical tool is provided to assess how information is shared with patients with DSD and their families and should be refined by all stakeholders, notably interdisciplinary health professionals and patient representatives. © 2017 S.

Combining Behavioral Endocrinology and Experimental Economics: Testosterone and Social Decision Making

Science.gov (United States)

2011-01-01

Behavioral endocrinological research in humans as well as in animals suggests that testosterone plays a key role in social interactions. Studies in rodents have shown a direct link between testosterone and aggressive behavior1 and folk wisdom adapts these findings to humans, suggesting that testosterone induces antisocial, egoistic or even aggressive behavior2. However, many researchers doubt a direct testosterone-aggression link in humans, arguing instead that testosterone is primarily involved in status-related behavior3,4. As a high status can also be achieved by aggressive and antisocial means it can be difficult to distinguish between anti-social and status seeking behavior. We therefore set up an experimental environment, in which status can only be achieved by prosocial means. In a double-blind and placebo-controlled experiment, we administered a single sublingual dose of 0.5 mg of testosterone (with a hydroxypropyl-β-cyclodextrin carrier) to 121 women and investigated their social interaction behavior in an economic bargaining paradigm. Real monetary incentives are at stake in this paradigm; every player A receives a certain amount of money and has to make an offer to another player B on how to share the money. If B accepts, she gets what was offered and player A keeps the rest. If B refuses the offer, nobody gets anything. A status seeking player A is expected to avoid being rejected by behaving in a prosocial way, i.e. by making higher offers. The results show that if expectations about the hormone are controlled for, testosterone administration leads to a significant increase in fair bargaining offers compared to placebo. The role of expectations is reflected in the fact that subjects who report that they believe to have received testosterone make lower offers than those who say they believe that they were treated with a placebo. These findings suggest that the experimental economics approach is sensitive for detecting neurobiological effects as subtle

More similar than you think: Frog metamorphosis as a model of human perinatal endocrinology.

Buchholz, Daniel R

Hormonal control of development during the human perinatal period is critically important and complex with multiple hormones regulating fetal growth, brain development, and organ maturation in preparation for birth. Genetic and environmental perturbations of such hormonal control may cause irreversible morphological and physiological impairments and may also predispose individuals to diseases of adulthood, including diabetes and cardiovascular disease. Endocrine and molecular mechanisms that regulate perinatal development and that underlie the connections between early life events and adult diseases are not well elucidated. Such mechanisms are difficult to study in uterus-enclosed mammalian embryos because of confounding maternal effects. To elucidate mechanisms of developmental endocrinology in the perinatal period, Xenopus laevis the African clawed frog is a valuable vertebrate model. Frogs and humans have identical hormones which peak at birth and metamorphosis, have conserved hormone receptors and mechanisms of gene regulation, and have comparable roles for hormones in many target organs. Study of molecular and endocrine mechanisms of hormone-dependent development in frogs is advantageous because an extended free-living larval period followed by metamorphosis (1) is independent of maternal endocrine influence, (2) exhibits dramatic yet conserved developmental effects induced by thyroid and glucocorticoid hormones, and (3) begins at a developmental stage with naturally undetectable hormone levels, thereby facilitating endocrine manipulation and interpretation of results. This review highlights the utility of frog metamorphosis to elucidate molecular and endocrine actions, hormone interactions, and endocrine disruption, especially with respect to thyroid hormone. Knowledge from the frog model is expected to provide fundamental insights to aid medical understanding of endocrine disease, stress, and endocrine disruption affecting the perinatal period in humans

Parental obesity is a risk factor for childhood obesity. The aim of this study was to determine if parental obesity influences the adherence and success of obesity treatment in a hospital paediatric endocrinology clinic. An analytical, prospective, longitudinal study was conducted on obese children aged 4-14. An initial body mass index (BMI), and again at 6 months after receiving health, hygiene and dietary recommendations. Success was considered as a decrease of 0.5 in the BMI Z-score, and adherence to attending the 6-month review. Parental BMI was determined to identify overweight. The χ(2) test was used for qualitative variables and the T-Student test for quantitative (significance, p3). More than half (59%) of the children had one or both parents obese (41 fathers and 37 mothers were obese). Treatment was not adhered to by 25 children. Adherence was worse if both parents were obese OR 3.65 (1.3 to 10.5) (P<=.01) and adherence was better if the mother was not obese, although the father was (P=.01). The treatment had significant success in 40 patients. If the mother was the only obese one in the family, the possibility of treatment failure was greater OR 5.6 (1.4 to 22.4) (P<.01) CONCLUSIONS: A high percentage of children with severe obesity have obese parents. The mother has an important influence on adherence and response to treatment for the severely obese child. Copyright © 2014 Asociación Española de Pediatría. Published by Elsevier España, S.L.U.

The aim of this study was to evaluate the strategy and efficacy of a hyperglycemia treatment program supervised by Endocrinology. All patients with type 2 diabetes hospitalized at the vascular surgery department over a 12 month period were retrospectively reviewed. Clinical characteristics and hyperglycemia treatment during hospitalization, at discharge and 2-6 month after discharge were collected. Glycemic control was assessed using capillary blood glucose profiles and HbA1c at admission and 2-6 months post-discharge. A total of 140 hospitalizations of 123 patients were included. The protocol to choose the insulin regimen was applied in 96.4% of patients (22.8% correction dose, 23.6% basal-correction dose and 50% basal-bolus-correction dose [BBC]). Patients with BBC had higher HbA1c (7.7±1.5% vs. 6.7 ±0.8%; P<.001) and mean glycemia on the first day of hospitalization (184.4±59.2 vs. 140.5±31.4mg/dl; P<.001). Mean blood glucose was reduced to 162.1±41.8mg/dl in the middle and 160.8±43.3mg/dl in the last 24h of hospitalization in patients with BBC (P=.007), but did not change in the remaining patients. In 22.1% patients with treatment changes performed at discharge, HbA1c decreased from 8.2±1.6 to 6.8±1.6% at 2-6 months post-discharge (P=.019). The hyperglycemia treatment protocol applied by an endocrinologist in the hospital, allows the identification of the appropriate therapy and the improvement of the glycemic control during hospitalization and discharge, supporting its efficacy in clinical practice.

Full Text Available Abstract Main progresses in endocrinology, gastroenterology, hemato-oncology, infectious diseases, otolaryngology, pharmacotherapy, and respiratory tract illnesses selected from articles published in The Italian Journal of Pediatrics in 2011 were reviewed. Risk factors for gastroenteritis and appendicitis in developing countries may be useful in improving our understanding of these diseases. Childhood hearing impairment is a world-wide problem which continues to have an high prevalence in newborns. Among the mechanisms of diseases, obese children often have asthma and high hepcidin levels that may reduce serum iron concentrations. In cystic fibrosis, 18q distal deletion has been described as a novel mutation. Hypothyroidism in children with central nervous system infections may increase mortality rates. Infrared tympanic thermometer (IRTT in oral mode for the measurement of body temperature may be useful in fever screening in a busy setup. In newborns, the transmission of CMV infection through breast milk may be prevented through freezing or pasteurization. Recent advances in treatment of constipation, urinary tract infections, leukemia, pain in children with cancer, neonates with sepsis or difficult weaning from mechanical ventilation will likely contribute towards optimizing management of these common disorders. The work of the Family Pediatricians Medicines for Children Research Network aims to develop competence, infrastructure, networking and education for pediatric clinical trials.

MECHANISMS IN ENDOCRINOLOGY: Kidney involvement in patients with primary hyperparathyroidism: an update on clinical and molecular aspects.

Primary hyperparathyroidism (PHPT) is the third most common endocrine disease. Kidney is a target of both chronic elevated PTH and calcium in PHPT. The classic PHPT complications of symptomatic kidney stones and nephrocalcinosis have become rare and the PHPT current presentation is asymptomatic with uncertain and long-lasting progression. Nonetheless, the routine use of imaging and of biochemical determinations have revealed the frequent occurrence of asymptomatic kidney stones, hypercalciuria and reduced kidney function in asymptomatic PHPT patients. Though the pathogenesis is far from being elucidated, PHPT is associated with reduced renal function, in terms of estimated glomerular filtration rate, and related increased morbidity and mortality. In the last decade, the effort of the Kidney Disease: Improving Global Outcomes (KDIGO) panel of experts highlighted that even mild reduction of kidney function is associated with increased risk of cardiovascular disease. These considerations provided the basis for the Fourth Workshop recommendations of a more extensive diagnostic workout about kidney features and of wider criteria for parathyroid surgery including asymptomatic kidney disease. Moreover, kidney involvement in PHPT is likely to be affected by variants of genes coding the key molecules regulating the calcium and ions renal handling; these features might have clinical relevance and should be considered both during diagnostic workout and follow-up. Finally, the effects of parathyroid surgery and of medical treatment on kidney involvement of PHPT are reviewed. © 2017 European Society of Endocrinology.

The United States lacks timely reliable mechanisms for assessing the professional work of subspecialty physicians. The aim was to use early-career members of The Endocrine Society as a model to estimate subspecialty physician involvement in patient care, teaching, research, and administration among clinical, academic, federal, and pharmaceutical/biotech workplaces and to assess the workforce for research within individual workplaces. Physicians joining The Endocrine Society from 1991-2005 and residing in North America were invited to complete a Web-based survey. This report relies on 817 early-career endocrinologists or 29.6% of eligible respondents. Respondents from all types of workplaces engaged in patient care, teaching, research, and administration. The time committed to the four tasks, however, differed significantly among workplaces. Research (basic, translational, disease, patient, population, and prevention) was accomplished within all workplaces, but the scope and scale of investigative work was employer dependent. Recipients of National Institutes of Health K08/23 awards succeeded in receiving federal research project grants (P Women in academic settings earned less than men (P < 0.01) and were less likely to occupy tenure-eligible positions (P < 0.01). Web-based surveys offer a simple tool for estimating the work of subspecialty physicians and provide a framework for improving biomedical investigation. Several interventions should be considered for endocrinology: recruit physicians from underrepresented demographic groups, increase K08/23 awards, incentivize investigative careers, and improve the national infrastructure for biomedical research.

Clinically nonfunctioning pituitary adenomas (NFPA) are the most common pituitary tumors after prolactinomas. The absence of clinical symptoms of hormonal hypersecretion can contribute to the late diagnosis of the disease. Thus, the majority of patients seek medical attention for signs and symptoms resulting from mass effect, such as neuro-ophthalmologic symptoms and hypopituitarism. Other presentations include pituitary apoplexy or an incidental finding on imaging studies. Mass effect and hypopituitarism impose high morbidity and mortality. However, early diagnosis and effective treatment minimizes morbidity and mortality. In this publication, the goal of the Neuroendocrinology Department of the Brazilian Society of Endocrinology and Metabolism is to provide a review of the diagnosis and treatment of patients with NFPA, emphasizing that the treatment should be performed in reference centers. This review is based on data published in the literature and the authors' experience. (author)

Iodothyronine deiodinases represent a family of selenoproteins involved in peripheral and local homeostasis of thyroid hormone action. Deiodinases are expressed in multiple organs and thyroid hormone affects numerous biological systems, thus genetic variation in deiodinases may affect multiple clinical endpoints. Interest in clinical effects of genetic variation in deiodinases has clearly increased. We aimed to provide an overview for the role of deiodinase polymorphisms in human physiology and morbidity. In this systematic review, studies evaluating the relationship between deiodinase polymorphisms and clinical parameters in humans were eligible. No restrictions on publication date were imposed. The following databases were searched up to August 2013: Pubmed, EMBASE (OVID-version), Web of Science, COCHRANE Library, CINAHL (EbscoHOST-version), Academic Search Premier (EbscoHOST-version), and ScienceDirect. Deiodinase physiology at molecular and tissue level is described, and finally the role of these polymorphisms in pathophysiological conditions is reviewed. Deiodinase type 1 (D1) polymorphisms particularly show moderate-to-strong relationships with thyroid hormone parameters, IGF1 production, and risk for depression. D2 variants correlate with thyroid hormone levels, insulin resistance, bipolar mood disorder, psychological well-being, mental retardation, hypertension, and risk for osteoarthritis. D3 polymorphisms showed no relationship with inter-individual variation in serum thyroid hormone parameters. One D3 polymorphism was associated with risk for osteoarthritis. Genetic deiodinase profiles only explain a small proportion of inter-individual variations in serum thyroid hormone levels. Evidence suggests a role of genetic deiodinase variants in certain pathophysiological conditions. The value for determination of deiodinase polymorphism in clinical practice needs further investigation. © 2014 European Society of Endocrinology.

Though it is well appreciated that insulin plays an important role in the regulation of muscle protein metabolism, there is much discrepancy in the literature on the capacity of exogenous insulin administration to increase muscle protein synthesis rates in vivo in humans. To assess whether exogenous insulin administration increases muscle protein synthesis rates in young and older adults. A systematic review of clinical trials was performed and the presence or absence of an increase in muscle protein synthesis rate was reported for each individual study arm. In a stepwise manner, multiple models were constructed that excluded study arms based on the following conditions: model 1, concurrent hyperaminoacidemia; model 2, insulin-induced hypoaminoacidemia; model 3, supraphysiological insulin concentrations; and model 4, older, more insulin resistant, subjects. From the presented data in the current systematic review, we conclude that: i) exogenous insulin and amino acid administration effectively increase muscle protein synthesis, but this effect is attributed to the hyperaminoacidemia; ii) exogenous insulin administered systemically induces hypoaminoacidemia which obviates any insulin-stimulatory effect on muscle protein synthesis; iii) exogenous insulin resulting in supraphysiological insulin levels exceeding 50, 000  pmol/l may effectively augment muscle protein synthesis; iv) exogenous insulin may have a diminished effect on muscle protein synthesis in older adults due to age-related anabolic resistance; and v) exogenous insulin administered systemically does not increase muscle protein synthesis in healthy, young adults. © 2015 European Society of Endocrinology.

To compare rates of clinical pregnancy (CPR) and live birth (LBR) following embryo transfer (ET) performed by reproductive endocrinology and infertility (REI) fellows before and after a prolonged lapse in clinical training due to an 18-month research rotation. Retrospective cohort study. Not applicable. All women undergoing in vitro fertilization (IVF) and IVF-intracytoplasmic sperm injection (ICSI) cycles with ET performed by REI fellows from August 2003 to July 2012. Eighteen-month lapse in clinical training of REI fellows. CPR and LBR before and after the lapse in clinical training were calculated and compared per fellow and as a composite group. Alternating logistic regression models were used to calculate the odds of clinical pregnancy and live birth following transfers performed before and after the lapse in training. Unadjusted odds of clinical pregnancy and live birth were similar between the two time periods both for individual fellows and for the composite group. Alternate logistic regression analysis revealed no significant difference in CPR (odds ratio [OR] 0.94, 95% confidence interval [CI] 0.83-1.07) or LBR (OR 1.05, 95% CI 0.94-1.18) after the lapse in training compared with before. A research rotation is common in REI fellowship training programs. This prolonged departure from clinical training does not appear to negatively affect pregnancy outcome following fellow ET.

Essential learning tools for continuing medical education are a challenge in today's rapidly evolving field of reproductive medicine. The Midwest Reproductive Symposium International (MRSi) is a yearly conference held in Chicago, IL. The conference is targeted toward physicians, geneticists, nurses, allied health professionals, mental health professionals, business administration professionals, and reproductive endocrinology and infertility (REI) fellows engaged in the practice of reproductive medicine. In addition to the scientific conference agenda, there are specific sessions for nurses, mental health professionals, and REI fellows. Unique to the MRSi conference, there is also a separate "Business Minds" session to provide education on business acumen as it is an important element to running a department, division, or private clinic.

This review will provide new information related to pathophysiology and management of specific diseases that have been addressed by selected articles published in the Italian Journal of Pediatrics in 2013, focusing on allergology, endocrinology, gastroenterology, hypertension, infectious diseases, neonatology, neurology, nutrition and respiratory tract illnesses in children. Recommendations for interpretation of skin prick test to foods in atopic eczema, management of allergic conjunctivitis, hypertension and breastfeeding in women treated with antiepileptic drugs and healthy breakfast have been reported. Epidemiological studies have given emphasis to high incidence of autoimmune disorders in patients with Turner syndrome, increasing prevalence of celiac disease, frequency of hypertension in adolescents, incidence and risk factor for retinopathy of prematurity. Advances in prevention include elucidation of the role of probiotics in reducing occurrence of allergies and feeding intolerance, and events of foetal life that influence later onset of diseases. Mechanistic studies suggested a role for vitamin D deficiency in asthma and type 1 diabetes and for reactivation of Varicella-Zoster virus in aseptic meningitis. Regarding diagnosis, a new mean for the diagnosis of hyperbilirubinaemia in newborns, a score for recognition of impaired nutritional status and growth and criteria for early Dyke-Davidoff-Masson Syndrome have been suggested. New therapeutic approaches consist of use of etanercept for reducing insulin dose in type 1 diabetes, probiotics in atopic eczema, and melatonin in viral infections.

To design and evaluate an ET simulator to train Reproductive Endocrinology and Infertility (REI) fellows' techniques of ET. Simulation model development and retrospective cohort analysis. Not applicable. Patients undergoing IVF. Simulation model evaluation and implementation of ET simulation training. Pregnancy rates. The REI fellow and faculty evaluation responses (n = 19/21 [90%]) of the model demonstrated realistic characteristics, with evaluators concluding the model was suitable for training in almost all evaluated areas. A total of 12 REI fellows who performed ET were analyzed: 6 before ET trainer and 6 after ET trainer. Pregnancy rates were 31% in the initial 10 ETs per fellow before simulator vs. 46% after simulator. One of six pre-ET trainer fellows (17%) had pregnancy rates ≥40% in their first 10 ETs; whereas four of six post-ET trainer fellows had pregnancy rates ≥40% in their first 10 ETs. The average number of ETs to obtain >40% pregnancy efficiency was 27 ETs before trainer vs. 15 ETs after trainer. Pregnancy rates were similar in the two groups after 20 ETs, and collective terminal pregnancy rates were >50% after 40 ETs. Embryo transfer simulation improved REI fellow pregnancy rates in their first 10 transfers and led to a more rapid ET proficiency. These data suggest potential value in adopting ET simulation, even in programs with a robust history of live ET in fellowship training. Published by Elsevier Inc.

Sporting activity is becoming a common practice in patients with diabetes mellitus (DM). This situation requires both a preliminary medical assessment and a wide range of changes in treatment which have scarcely been addressed in medical literature. To prepare a clinical guideline on the medical approach to patients with diabetes who practice sport regularly. An expert panel from the Diabetes Mellitus Working Group of the Spanish Society of Endocrinology and Nutrition (SEEN) reviewed the most relevant literature in each of the sections. Based both on this review and on data from the experience of a number of athletes with DM, a number of recommendations were agreed within each section. Finally, the Working Group and representatives of the SEEN jointly discussed all these recommendations. The guideline provides recommendations ranging from medical assessment before patients with DM start to practice sport to actions during and after physical activity. Recommendations are also given on aspects such as the impact of sport on blood glucose control, training schemes, or special risk situations. Copyright © 2015 SEEN.

Kaser, Daniel J

2017-03-01

Fellows in Reproductive Endocrinology and Infertility training are expected to complete 18 months of clinical, basic, or epidemiological research. The goal of this research is not only to provide the basis for the thesis section of the oral board exam but also to spark interest in reproductive medicine research and to provide the next generation of physician-scientists with a foundational experience in research design and implementation. Incoming fellows often have varying degrees of training in research methodology and, likewise, different career goals. Ideally, selection of a thesis topic and mentor should be geared toward defining an "answerable" question and building a practical skill set for future investigation. This contribution to the JARG Young Investigator's Forum revisits the steps of the scientific method through the lens of one recently graduated fellow and his project aimed to test the hypothesis that "sequential oxygen exposure (5% from days 1 to 3, then 2% from days 3 to 5) improves blastocyst yield and quality compared to continuous exposure to 5% oxygen among human preimplantation embryos."

To investigate the differences in bone turnover between diabetic patients and controls. A systematic review and meta-analysis. A literature search was conducted using the databases Medline at PubMed and EMBASE. The free text search terms 'diabetes mellitus' and 'bone turnover', 'sclerostin', 'RANKL', 'osteoprotegerin', 'tartrate-resistant acid' and 'TRAP' were used. Studies were eligible if they investigated bone turnover markers in patients with diabetes compared with controls. Data were extracted by two reviewers. A total of 2881 papers were identified of which 66 studies were included. Serum levels of the bone resorption marker C-terminal cross-linked telopeptide (-0.10 ng/mL (-0.12, -0.08)) and the bone formation markers osteocalcin (-2.51 ng/mL (-3.01, -2.01)) and procollagen type 1 amino terminal propeptide (-10.80 ng/mL (-12.83, -8.77)) were all lower in patients with diabetes compared with controls. Furthermore, s-tartrate-resistant acid phosphatase was decreased in patients with type 2 diabetes (-0.31 U/L (-0.56, -0.05)) compared with controls. S-sclerostin was significantly higher in patients with type 2 diabetes (14.92 pmol/L (3.12, 26.72)) and patients with type 1 diabetes (3.24 pmol/L (1.52, 4.96)) compared with controls. Also, s-osteoprotegerin was increased among patients with diabetes compared with controls (2.67 pmol/L (0.21, 5.14)). Markers of both bone formation and bone resorption are decreased in patients with diabetes. This suggests that diabetes mellitus is a state of low bone turnover, which in turn may lead to more fragile bone. Altered levels of sclerostin and osteoprotegerin may be responsible for this. © 2017 European Society of Endocrinology.

Routine thyroid ultrasound examination in a single medical appointment is rarely performed in Spain. The objective of this study was to evaluate the care and economic impact of thyroid US examination in a single endocrine appointment. A prospective, observational, descriptive study was conducted to analyze data from 2274 patients (mean age, 59±16 years; 83% females) performed at least one thyroid US in a single visit to an endocrinology clinic during 2013 and 2014. The number of endocrine acts with thyroid US, single endocrine and US acts without review, and the change in the number of thyroid US requested by endocrinologists to the radiology department and total thyroid US examinations performed at the radiology department during the study period were assessed. In 2013 and 2014, 2558 endocrine acts with thyroid US were performed, of which 42.2% were single endocrine and US appointments without a second endocrine act, with estimated savings of €58,946.40. As compared to 2012, the number of thyroid US requested by endocrinologists to the radiology department decreased by 43.3% and 86.0% in 2013 and 2014 respectively, and total thyroid US performed by the radiology department decreased by 28.1% and 68.3% respectively, with estimated savings of €94,441.36. Thyroid US examination in a single endocrine appointment allows for decreasing the number of both second endocrine acts and thyroid US examinations performed at the radiology department, thus reducing the number of unnecessary clinic visits and promoting considerable economic savings.

This study aimed to identify the dropout rate at 6 and 12 months from the first outpatient visit, and to analyze dropout risk factors among the following areas: biochemical examinations, anthropometric measures, psychological tests, personal data, and life attitude such as smoking, physical activity, and pathologies. This is a retrospective longitudinal observational study. Patients undergo an outpatient endocrinology visit, which includes collecting biographical data, anthropometric measurements, physical and pathological history, psychological tests, and biochemical examinations. The sample consists of 913 subjects (682 women and 231 men), with an average age of 50.88 years (±15.80) for the total sample, with a BMI of 33.11 ± 5.65 kg/m 2 . 51.9% of the patients abandoned therapy at 6 months after their first visit, and analyzing the dropout rate at 12 months, it appears that 69.5% of subjects abandon therapy. The main predictor of dropout risk factors at 6 and 12 months is the weight loss during the first 3 months (p dropout at 12 months.

Xie, Zhenzhen; Or, Calvin

2017-01-01

The issue of long patient waits has attracted increasing public attention due to the negative effects of waiting on patients' satisfaction with health care. The present study examined the associations between actual waiting time, perceived acceptability of waiting time, actual service time, perceived acceptability of service time, actual visit duration, and the level of patient satisfaction with care. We conducted a cross-sectional time study and questionnaire survey of endocrinology outpatients visiting a major teaching hospital in China. Our results show that actual waiting time was negatively associated with patient satisfaction regarding several aspects of the care they received. Also, patients who were less satisfied with the sociocultural atmosphere and the identity-oriented approach to their care tended to perceive the amounts of time they spent waiting and receiving care as less acceptable. It is not always possible to prevent dissatisfaction with waiting, or to actually reduce waiting times by increasing resources such as increased staffing. However, several improvements in care services can be considered. Our suggestions include providing clearer, more transparent information to keep patients informed about the health care services that they may receive, and the health care professionals who are responsible for those services. We also suggest that care providers are encouraged to continue to show empathy and respect for patients, that patients are provided with private areas where they can talk with health professionals and no one can overhear, and that hospital staff treat the family members or friends who accompany patients in a courteous and friendly way.

To help celebrate the 50th anniversary of General and Comparative Endocrinology, the history of only a small portion of crustacean endocrinology is presented here. The field of crustacean endocrinology dates back to the decades prior to the establishment of General and Comparative Endocrinology and the first article about crustacean endocrinology published in this journal was concerned with the anatomy of neurosecretory and neurohemal structures in brachyuran crabs. This review looks at the history of neuroendocrinology in crustaceans during that time and tries to put perspective on the future of this field. Copyright © 2011 Elsevier Inc. All rights reserved.

Full Text Available To assess the prevalence of osteoporosis and osteopenia among Jordanian postmenopausal women attending the National Center for Diabetes, Endocrinology, and Genetics (NCDEG, and to determine the potential associated risk factors. A cross-sectional study was conducted at (NCDEG in Amman, Jordan. A total of 1079 Jordanian postmenopausal women aged between 45 and 84 years were included in this study that was conducted during the period between April 2013 and December 2014. All patients underwent bone mineral density measurement through dual-energy X-ray absorptiometry (DEXA scan. DEXA scan was interpreted in terms of T score as per World Health Organization guidelines. The overall prevalence of osteoporosis and osteopenia was 37.5% and 44.6%, respectively. The maximum prevalence of osteoporosis was observed at the lumbar spine (32.4% followed by the left femoral neck (14.4%, while the maximum prevalence of osteopenia was observed at the left femoral neck (56.1% followed by the lumbar spine (41.3%. Patients with longer menopausal duration, normal or overweight body mass index, high parity, physical inactivity, positive family history of osteoporosis, inadequate sun exposure, high daily caffeine intake, low daily calcium intake, and delay in the age of menarche were all positively associated with osteoporosis. On the other hand, women with type 2 diabetes mellitus had lower risk of osteoporosis. There is a high prevalence of osteoporosis and osteopenia among Jordanian postmenopausal women. Necessary steps are needed for more public education and a wider dissemination of information about osteoporosis and its prevention.

MECHANISMS IN ENDOCRINOLOGY: Skeletal muscle lipotoxicity in insulin resistance and type 2 diabetes: a causal mechanism or an innocent bystander?

Science.gov (United States)

Brøns, Charlotte; Grunnet, Louise Groth

2017-02-01

Dysfunctional adipose tissue is associated with an increased risk of developing type 2 diabetes (T2D). One characteristic of a dysfunctional adipose tissue is the reduced expandability of the subcutaneous adipose tissue leading to ectopic storage of fat in organs and/or tissues involved in the pathogenesis of T2D that can cause lipotoxicity. Accumulation of lipids in the skeletal muscle is associated with insulin resistance, but the majority of previous studies do not prove any causality. Most studies agree that it is not the intramuscular lipids per se that causes insulin resistance, but rather lipid intermediates such as diacylglycerols, fatty acyl-CoAs and ceramides and that it is the localization, composition and turnover of these intermediates that play an important role in the development of insulin resistance and T2D. Adipose tissue is a more active tissue than previously thought, and future research should thus aim at examining the exact role of lipid composition, cellular localization and the dynamics of lipid turnover on the development of insulin resistance. In addition, ectopic storage of fat has differential impact on various organs in different phenotypes at risk of developing T2D; thus, understanding how adipogenesis is regulated, the interference with metabolic outcomes and what determines the capacity of adipose tissue expandability in distinct population groups is necessary. This study is a review of the current literature on the adipose tissue expandability hypothesis and how the following ectopic lipid accumulation as a consequence of a limited adipose tissue expandability may be associated with insulin resistance in muscle and liver. © 2017 European Society of Endocrinology.

At the same time Lopez and coworkers published on the Annals of Internal Medicine an important study showing that even patients with non-functioning adrenal tumors have an increased risk of incident diabetes. In consideration of previous data and of the results of the study of Lopez and coworkers, some points emerge from the ESE Guidelines that deserve attention. Firstly, it must be observed that the term "autonomous cortisol secretion," introduced by the ESE Panel in the place of the commonly used "subclinical hypercortisolism," seems questionable, since the guidelines do not suggest determining the adrenocorticotroph hormone levels that could give the certain proof of a truly autonomous cortisol secretion. Secondly, the ESE Guidelines suggest against repeated hormonal workup in AI patients with a normal hormonal secretion at initial evaluation, but also in those with a "possible autonomous cortisol secretion," if in the absence of comorbidities potentially related to hypercortisolism. Thirdly, the ESE Guidelines suggest against further imaging during follow-up in patients with an adrenal mass below 4 cm in size with clear benign features on imaging studies. Considering the available literature data that are briefly summarized in this comment, we believe that no sufficient evidence is available to date for giving sharp-cutting recommendations about the uselessness of a biochemical and morphological follow-up in AI patients, even in those with initially benign and not hypersecreting adrenal adenomas. However, if a recommendation has to be given on the basis of the present evidences, we should suggest to biochemically and morphologically follow-up AI patients for at least 5 years.

To provide practical recommendations for evaluation and treatment of osteoporosis associated to endocrine diseases and nutritional conditions. Members of the Bone Metabolism Working Group of the Spanish Society of Endocrinology, a methodologist, and a documentalist. Recommendations were formulated according to the GRADE system (Grading of Recommendations, Assessment, Development, and Evaluation) to describe both the strength of recommendations and the quality of evidence. A systematic search was made in MEDLINE (Pubmed), using the following terms associated to the name of each condition: AND "osteoporosis", "fractures", "bone mineral density", and "treatment". Papers in English with publication date before 18 October 2011 were included. Current evidence for each disease was reviewed by two group members, and doubts related to the review process or development of recommendations were resolved by the methodologist. Finally, recommendations were discussed in a meeting of the Working Group. The document provides evidence-based practical recommendations for evaluation and management of endocrine and nutritional diseases associated to low bone mass or an increased risk of fracture. For each disease, the associated risk of low bone mass and fragility fractures is given, recommendations for bone mass assessment are provided, and treatment options that have shown to be effective for increasing bone mass and/or to decreasing fragility fractures are listed.

Hyperthyroidism is characterized by increased synthesis and release of thyroid hormones by the thyroid gland. Thyrotoxicosis refers to the clinical syndrome resulting from excessive circulating thyroid hormones, secondary to hyperthyroidism or due to other causes. This article describes evidence-based guidelines for the clinical management of thyrotoxicosis. This consensus, developed by Brazilian experts and sponsored by the Department of Thyroid Brazilian Society of Endocrinology and Metabolism, aims to address the management, diagnosis and treatment of patients with thyrotoxicosis, according to the most recent evidence from the literature and appropriate for the clinical reality of Brazil. After structuring clinical questions, search for evidence was made available in the literature, initially in the database MedLine, PubMed and Embase databases and subsequently in SciELO - Lilacs. The strength of evidence was evaluated by Oxford classification system was established from the study design used, considering the best available evidence for each question. We have defined 13 questions about the initial clinical approach for the diagnosis and treatment that resulted in 53 recommendations, including the etiology, treatment with antithyroid drugs, radioactive iodine and surgery. We also addressed hyperthyroidism in children, teenagers or pregnant patients, and management of hyperthyroidism in patients with Graves' ophthalmopathy and various other causes of thyrotoxicosis. The clinical diagnosis of hyperthyroidism usually offers no difficulty and should be made with measurements of serum TSH and thyroid hormones. The treatment can be performed with antithyroid drugs, surgery or administration of radioactive iodine according to the etiology of thyrotoxicosis, local availability of methods and preferences of the attending physician and patient.

Development of these guidelines is mandated by the American Association of Clinical Endocrinologists (AACE) Board of Directors and the American College of Endocrinology (ACE) Board of Trustees and adheres to published AACE protocols for the standardized production of clinical practice guidelines (CPGs). Recommendations are based on diligent review of clinical evidence with transparent incorporation of subjective factors. There are 9 broad clinical questions with 123 recommendation numbers that include 160 specific statements (85 [53.1%] strong [Grade A], 48 [30.0%] intermediate [Grade B], and 11 [6.9%] weak [Grade C], with 16 [10.0%] based on expert opinion [Grade D]) that build a comprehensive medical care plan for obesity. There were 133 (83.1%) statements based on strong (best evidence level [BEL] 1 = 79 [49.4%]) or intermediate (BEL 2 = 54 [33.7%]) levels of scientific substantiation. There were 34 (23.6%) evidence-based recommendation grades (Grades A-C = 144) that were adjusted based on subjective factors. Among the 1,788 reference citations used in this CPG, 524 (29.3%) were based on strong (evidence level [EL] 1), 605 (33.8%) were based on intermediate (EL 2), and 308 (17.2%) were based on weak (EL 3) scientific studies, with 351 (19.6%) based on reviews and opinions (EL 4). The final recommendations recognize that obesity is a complex, adiposity-based chronic disease, where management targets both weight-related complications and adiposity to improve overall health and quality of life. The detailed evidence-based recommendations allow for nuanced clinical decision-making that addresses real-world medical care of patients with obesity, including screening, diagnosis, evaluation, selection of therapy, treatment goals, and individualization of care. The goal is to facilitate high-quality care of patients with obesity and provide a rational, scientific approach to management that optimizes health outcomes and safety.

Long-lasting problem on the differentiation of adenohypophyseal cell, which prepares them for their specific tasks (somatotropic, lactotropic ect.), becomes elucidated after recognition of the differentiational effect of transcription factor Pit-1. Expression of that factor in somatotrops results in STH secretion, contrary to lactotrops producing prolactin. Subclinical hypothyreosis (increased TSH with normal T3 and T4) endangers vessel not because of hypercholesterolemia, but because of changes in the dynamics of the blood flow. The idea of cardiotropic effect of thyroidal hormones is supported by the finding that administration of trijodthyronine to children after the surgical correction of heart malformations (cardiopulmonary bypass) improves myocardial function--it elevates cardiac output and decreases requirements on the intensive care. Receptors for hormones in tissues are flexible, they can be "heterooligomers" for dopamine and somatostatin. Mutations of mineralocorticoid receptor may cause hypertension in pregnancy and progesterone receptors have several isoforms. Receptors can be also activated by short exposition to a hormone. Glucocorticoids have probably also membrane receptors. Diabetes mellitus "type I" needn't to be immunogenic and DM type II not only results from down-regulation of receptors and subsequent insulin resistance, but it can be also caused by defects in insulin secretion. Insulin has receptors in the brain and participates in the appetite regulation. The attempt to use "desensibilisation" by peroraly administered insulin in patients with immunogenic DM had no effect. Stress affects memory mechanisms, heavy emotional stress during gravidity can bring congenital malformations. The decrease of mental functions in aged women depends on the level of free estradiol (the fraction, which is not bound to plasma proteins). Activation of dopaminergic neurons can be achieved by neurotropic growth factors. Nesiritide is a recombinant brain natriuretic hormone successfully tested in heart failure. The role of leptin in the appetite regulation in man is still not clear, other signalling molecules may have also an effect, e.g., ghrelin, which primarily stimulates STH secretion and brings about weight gain. Sildenafil influences nitrergic neurons elsewhere than in penis, for example it has positive effects in patients with oesophageal achalasia.

The myometrium must remain relatively quiescent during pregnancy to accommodate growth and development of the feto-placental unit, and then must transform into a highly coordinated, strongly contracting organ at the time of labour for successful expulsion of the new born. The control of timing of labour is complex involving interactions between mother, fetus and the placenta. The timely onset of labour and delivery is an important determinant of perinatal outcome. Both preterm birth (delivery before 37 week of gestation) and post term pregnancy (pregnancy continuing beyond 42 weeks) are both associated with a significant increase in perinatal morbidity and mortality. There are multiple paracrine/autocrine events, fetal hormonal changes and overlapping maternal/fetal control mechanisms for the triggering of parturition in women. Our current article reviews the mechanisms for uterine distension and reduced contractions during pregnancy and the parturition cascade responsible for the timely and spontaneous onset of labour at term. It also discusses the mechanisms of preterm labour and post term pregnancy and the clinical implications thereof. PMID:23776853

Endocrinology Update: Hypopituitarism.

Science.gov (United States)

Heidelbaugh, Joel J

2016-12-01

Hypopituitarism is defined as a deficiency of one or more pituitary hormones due to a decline in function of the pituitary gland and/or hypothalamus, which can result in higher risks of morbidity and mortality and decreased quality of life. Although hypopituitarism is a rare condition, it commonly develops after traumatic brain injury and in the setting of functioning and nonfunctioning pituitary adenomas. The diagnosis is based on detailed investigation of symptoms of target endocrine gland function relative to the corresponding pituitary hormone deficiency. The clinical manifestations of hypopituitarism result from the degree of the specific hormone deficiency. A thorough and longitudinal history and physical examination, including visual field testing, are paramount. Management consists of prompt pharmacotherapy, surgery, and/or radiotherapy to restore normal endocrine function and quality of life. In most patients with anterior and posterior pituitary hormone deficiency, corresponding hormone replacement is the mainstay of therapy. The prognosis for patients with hypopituitarism depends on the manner of and age at presentation, degree and severity of hormonal impairment, and response to medical and surgical therapies. Patients with hypopituitarism require lifelong monitoring of serum hormone levels and symptoms of hormone deficiency or excess.

Subclinical hypothyroidism (SCH), defined as elevated concentrations of thyroid stimulating hormone (TSH) despite normal levels of thyroid hormones, is highly prevalent in Brazil, especially among women and the elderly. Although an increasing number of studies have related SCH to an increased risk of coronary artery disease and mortality, there have been no randomized clinical trials verifying the benefit of levothyroxine treatment in reducing these risks, and the treatment remains controversial. This consensus, sponsored by the Thyroid Department of the Brazilian Society of Endocrinology and Metabolism and developed by Brazilian experts with extensive clinical experience with thyroid diseases, presents these recommendations based on evidence for the clinical management of SCH patients in Brazil. After structuring the clinical questions, the search for evidence in the literature was initially performed in the MedLine-PubMed database and later in the Embase and SciELO - Lilacs databases. The strength of evidence was evaluated according to the Oxford classification system and established based on the experimental design used, considering the best available evidence for each question and the Brazilian experience. The topics covered included SCH definition and diagnosis, natural history, clinical significance, treatment and pregnancy, and the consensus issued 29 recommendations for the clinical management of adult patients with SCH. Treatment with levothyroxine was recommended for all patients with persistent SCH with serum TSH values > 10 mU/L and for certain patient subgroups.

To evaluate the prevalence of hyperglycemia among inpatients in internal medicine, and specifically, to assess the glycemic management of inpatients in non-endocrinology departments in three large urban hospitals in China. A multicenter observational study was conducted using electronic health records, and a survey of 1939 patients who were admitted to internal medicine units and followed until discharge. Those with previously diagnosed diabetes, newly diagnosed diabetes, or impaired fasting glucose were included. Aspects of glycemic management examined were (a) hyperglycemia, (b) endocrinology consultation for hyperglycemia and (c) hypoglycemia. The prevalence of hyperglycemia in internal medicine was 45.7% (886 out of 1939). A total of 741 (83.6%) patients were treated by non-endocrinology departments; of those, 230 (31.1%) were in poor glycemic control and needed an endocrinology consultation. Yet only 57 (24.8%) received one. In 4 cases, the physician did not follow the consultants' advice. Among the remaining 53 consulted patients, 35 (66.1%) were still in poor glycemic control, yet only about half received a second consultation. Finally, among patients treated in non-endocrinology departments, 58 (7.8%) had hypoglycemia; less than half retested their blood glucose after treatment. The majority of patients with hyperglycemia were in non-endocrinology departments. Their glycemic management was poor; the endocrinology consultation rate was low and the result was suboptimal. Also, the management of hypoglycemia was not ideal. Therefore, improving glycemic management is urgently needed in Chinese hospitals.

CONSENSUS STATEMENT BY THE AMERICAN ASSOCIATION OF CLINICAL ENDOCRINOLOGISTS AND AMERICAN COLLEGE OF ENDOCRINOLOGY ON THE QUALITY OF DXA SCANS AND REPORTS.

High-quality dual-energy X-ray absorptiometry (DXA) scans are necessary for accurate diagnosis of osteoporosis and monitoring of therapy; however, DXA scan reports may contain errors that cause confusion about diagnosis and treatment. This American Association of Clinical Endocrinologists/American College of Endocrinology consensus statement was generated to draw attention to many common technical problems affecting DXA report conclusions and provide guidance on how to address them to ensure that patients receive appropriate osteoporosis care. The DXA Writing Committee developed a consensus based on discussion and evaluation of available literature related to osteoporosis and osteodensitometry. Technical errors may include errors in scan acquisition and/or analysis, leading to incorrect diagnosis and reporting of change over time. Although the International Society for Clinical Densitometry advocates training for technologists and medical interpreters to help eliminate these problems, many lack skill in this technology. Suspicion that reports are wrong arises when clinical history is not compatible with scan interpretation (e.g., dramatic increase/decrease in a short period of time; declines in previously stable bone density after years of treatment), when different scanners are used, or when inconsistent anatomic sites are used for monitoring the response to therapy. Understanding the concept of least significant change will minimize erroneous conclusions about changes in bone density. Clinicians must develop the skills to differentiate technical problems, which confound reports, from real biological changes. We recommend that clinicians review actual scan images and data, instead of relying solely on the impression of the report, to pinpoint errors and accurately interpret DXA scan images.

In this review, we summarize the progresses in allergy, endocrinology, gastroenterology, hematology, infectious diseases, neurology, nutrition and respiratory tract illnesses that have been published in The Italian Journal of Pediatrics in 2012. The induction of Treg activity by probiotics might be effective for promoting tolerance towards food allergens. Nasal cytology is useful in patients with rhinitis for diagnosing chronic non-allergic non-infectious diseases. Atopic eczema is associated both with an aberrant skin matrix and impaired systemic immune response. Therefore, isolated topical treatment may have suboptimal effect. Diagnostic work-up of exercise-induced anaphylaxis, including exercise challenge test, is necessary to reach a diagnosis. Studies may support a role for nutrition on prevention of asthma and cardiovascular diseases. Clinicians need to early identify adolescent menstrual abnormalities to minimize sequelae, and to promote health information. In Multiple Endocrine Neoplasia type 2B investigations include acetylcholinesterase study of rectal mucosa followed by the molecular analysis of RET mutation. Low adherence to gluten-free diet and osteopenia are common problems in children with diabetes mellitus type 1 and celiac disease. In infantile colic, laboratory tests are usually unnecessary and the treatment is based on reassurance. Prevalence of obesity and stunting is elucidated by several studies. Evidences are growing that dietetic measures are needed to prevent obesity in children with acute leukemia. Treatment studies for infectious diseases show promise for probiotics along with standard triple therapy in children with Helicobacter pilori infection, while zinc has no effect on pneumonia. Educational programs about the proper management of the febrile child are warranted. A new hour-specific total serum bilirubin nomogram has been shown to be able to predict newborns without hyperbilirubinemia after 48 to 72 hours of life. Newborns with

2521 patients of the Lodz Outpatient Endocrinologic Clinic (2290 females, 231 males; inhabitants of the central region of Poland were included in the study. The obtained results indicate that: 1) KI administration neither increased the number of exacerbations of hyperthyroidism nor affected the onset of new cases of that disease in 1986. 2) The same can be said about the cases of thyroiditis and hypothyroidism. 3) No increase of ATMA or ATG antibodies ''prevalence, as well as no elevation of those antibodies'' titres after KI prophylactic dose were observed in the patients with Grave's disease and chronic thyroiditis, when compared to persons who did not take Lugol's iodine. 4) The course of the majority of diseases diagnosed in 1986, evaluated with use of the, so called, test for analysis of trends, became unchanged. 5) There were adverse side effects noted after KI in 32 patients out of all the examined 774 patients (i.e., in 4.13%); five of the affected patients required medical care. 6) After iodine tincture; side effects occurred in three patients in the group of 35 patients included in the examination, i.e., in 8.57%; none of the affected patients required medical care. 7) Our results, comprising the four year observation period after Chernobyl accident, do not indicate any increased incidence of malignant neoplasms of the thyroid gland, what confirms the apparent theoretical data; much longer observation time is necessary to reveal phenomena of scholastic type (10-15 years).

A comprehensive survey was conducted courtesy of the Turkish Turner study group to evaluate the shortcomings of clinical care in patients with Turner syndrome (TS) in Turkey. A structured questionnaire prepared by the Turner study group in Turkey, which covers relevant aspects of the care of patients with TS, was sent to all pediatric endocrinology centers. Eighteen centers (41%) returned the questionnaire. In the majority of the centers, diagnostic genetic testing, screening for Y chromosomal material, protocols regarding the timing and posology of growth hormone (GH) and estrogen, thrombophilia screening, fertility information, and screening for glucose intolerance, thyroid, and coeliac diseases in patients with TS were in line with the current consensus. Thirteen centers (72.2%) performed GH stimulation tests. Only four centers (22.2%) used oxandrolone in patients with TS with very short stature. The majority of the centers relied on bone age and breast development to assess estrogen adequacy, though together with variable combinations of oestrogen surrogates. Two centers (11.1%) reported performing serum estradiol measurements. Eight centers (44.4% ) routinely conducted cardiac/thoracic aorta magnetic resonance imaging. Screening for hearing, dental, and ophthalmologic problems were performed by thirteen (72.2%), six (33.3%), and ten (55.6 %) centers, respectively. Psychiatric assessments were made by four centers (22.2%) at diagnosis, with only one center (5.6% ) requiring annual reassessments. Although we found some conformity between the current consensus and practice of the participating centers in Turkey regarding TS, further improvements are mandatory in the multi-disciplinary approach to address co-morbidities, which if unrecognized, may be associated with reduced quality of life, and even mortality.

We investigated hypertension and diabetes mellitus in two management settings, namely cardiology and endocrinology, and their associations with albuminuria while accounting for the management of these two diseases. Our multicentre registry included patients (≥20 years) seen for hypertension in cardiology or for diabetes mellitus in endocrinology. We administered a questionnaire and measured blood pressure, glycosylated haemoglobin A1c and albuminuria. Presence of both hypertension and diabetes was observed in 32.9% of hypertensive patients in cardiology (n = 1291) and 58.9% of diabetic patients in endocrinology (n = 1168). When both diseases were present, the use of combination antihypertensive therapy [odds ratio (OR) 0.31, P hypertension and diabetes, however, was not different between the two management settings (P ≥ 0.21), regardless of the therapeutic target (SBP/DBP hypertension (12.6%) or diabetes alone (15.9%).

Hormones play a critical role in maintaining body fluid balance in euryhaline fishes during changes in environmental salinity. The neuroendocrine axis senses osmotic and ionic changes, then signals and coordinates tissue-specific responses to regulate water and ion fluxes. Rapid-acting hormones, e.g. angiotensins, cope with immediate challenges by controlling drinking rate and the activity of ion transporters in the gill, gut, and kidney. Slow-acting hormones, e.g. prolactin and growth hormone/insulin-like growth factor-1, reorganize the body for long-term acclimation by altering the abundance of ion transporters and through cell proliferation and differentiation of ionocytes and other osmoregulatory cells. Euryhaline species exist in all groups of fish, including cyclostomes, and cartilaginous and teleost fishes. The diverse strategies for responding to changes in salinity have led to differential regulation and tissue-specific effects of hormones. Combining traditional physiological approaches with genomic, transcriptomic, and proteomic analyses will elucidate the patterns and diversity of the endocrine control of euryhalinity.

This article attempts to analyze the crucial link between the plant Agnus castus and human health, particularly hormonal status, with special reference to the needs of the society of ancient Sparta. The ancient Spartans used Agnus both as a cure for infertility and as a remedy to treat battle wounds. These special properties were recognized by the sanctuary of Asclepios Agnita, which was located in Sparta, as well as by medical practitioners in Sparta during the classical, Hellenistic and Roman ages.

The effect of intraoperative magnetic resonance imaging (iMRI) on the extent of sellar region tumors treated endonasally has been described in previous research. However, the effects of iMRI on endocrinologic outcome of growth hormone-secreting adenomas have been studied in only a few small cohort studies. Inclusion criteria were primary transsphenoidal surgery for growth hormone-secreting adenoma from January 2009 to December 2014, a minimum follow-up of 1 year, complete endocrinologic data, at least 1 iMRI, and at least 2 postoperative magnetic resonance images. The cohort consisted of 105 patients (54 females, 51 males) with a mean age of 48.3 years (range, 7-77 years). There were 16 microadenomas and 89 macroadenomas. Endocrinologic remission in the whole cohort was achieved in 64 of the patients (60.9%). Resection after iMRI was attempted in 22 of the cases (20.9%). Resection after iMRI led to hormonal remission in 9 cases (8.6%). Endocrinologic postoperative deficit was observed in 10 cases (12.5%). Postoperative cerebrospinal fluid leakage indicated the necessity to reoperate in 3 cases (3.8%). No neurologic deterioration was observed. iMRI influences not only the morphologic extent of pituitary adenomas resection but also the endocrinologic results. We encourage the routine application of iMRI in pituitary adenoma surgery, including hormone-secreting pituitary tumors. Copyright © 2016 Elsevier Inc. All rights reserved.

Turner syndrome affects 25-50 per 100,000 females and can involve multiple organs through all stages of life, necessitating multidisciplinary approach to care. Previous guidelines have highlighted this, but numerous important advances have been noted recently. These advances cover all specialty fields involved in the care of girls and women with TS. This paper is based on an international effort that started with exploratory meetings in 2014 in both Europe and the USA, and culminated with a Consensus Meeting held in Cincinnati, Ohio, USA in July 2016. Prior to this meeting, five groups each addressed important areas in TS care: 1) diagnostic and genetic issues, 2) growth and development during childhood and adolescence, 3) congenital and acquired cardiovascular disease, 4) transition and adult care, and 5) other comorbidities and neurocognitive issues. These groups produced proposals for the present guidelines. Additionally, four pertinent questions were submitted for formal GRADE (Grading of Recommendations, Assessment, Development and Evaluation) evaluation with a separate systematic review of the literature. These four questions related to the efficacy and most optimal treatment of short stature, infertility, hypertension, and hormonal replacement therapy. The guidelines project was initiated by the European Society for Endocrinology and the Pediatric Endocrine Society, in collaboration with The European Society for Pediatric Endocrinology, The Endocrine Society, European Society of Human Reproduction and Embryology, The American Heart Association, The Society for Endocrinology, and the European Society of Cardiology. The guideline has been formally endorsed by the European Society for Endocrinology, the Pediatric Endocrine Society, the European Society for Pediatric Endocrinology, the European Society of Human Reproduction and Embryology and the Endocrine Society.

Quantitative review and categorization of available endocrinology related mobile apps for the iOS platform (Apple®) and outline of search strategies to identify appropriate mobile apps for this field. A total of 80 endocrinology related search terms were collected and grouped into 8 main categories covering different areas of endocrinology. These terms were then used to perform comprehensive searches in three categories of Apple's app store, namely 'Medicine', 'Health and Fitness', and 'Reference'. Altogether, matches were found for only 33 of the 80 collected endocrinology related search terms; the majority of matches were found in the medical category, followed by matches for the health and fitness (27/33), and reference (16/33) categories. Restricting the search to these categories significantly helped in discriminating between health related apps and those having another purpose. The distribution of apps per category roughly matches what one can expect considering available data for incidence and prevalence of corresponding endocrinological conditions. Apps matching terms belonging to the spectrum of glucose homeostasis disorders are the most common. For conditions where patients do not have to constantly monitor their condition, apps tend to have a reference or educational character, while for conditions that require a high level of involvement from patients, there are proportionally more apps for self-management. With a single exception, the identified apps had not undergone regulation, and information about the data sources, professional backgrounds, and reliability of the content and integrated information sources was rare. While applying a good search strategy is important for finding apps for endocrinology related problems, users also need to consider whether the app they have found respects all necessary criteria regarding reliability, privacy and data protection before they place their trust in it.

We aim to study surgical technique and analyze the related factors affecting tumor total removal and postoperative endocrinological remission for endoscopic endonasal pituitary adenomas surgery. We retrospectively analyzed 178 endoscopic endonasal pituitary adenomas surgery from March 2011 to May 2014. Endonasal approach included the routine transnasal-sphenoidal approach, transnasal- maxillary sinus approach in four cases and transnasal-clivus approach in one case. According to postoperative imaging data and endocrine examination results, total removal was achieved in 129 patients (72.5%), and endocrinological remission was achieved in 38 patients with functional adenomas (44.1%). Statistical analysis of the clinical data showed that total removal rate was much closely related to tumor volume (P = 0.006), and tumor invasiveness (P < 0.001). In this study, we found tumor sizes and invasion of cavernous sinus were related to total removal rate and endocrinological remission rate; the direction and degree of tumor invasion, and the surgeon's experience were the key influence factors of the endocrinological remission rate for invasive functional pituitary adenomas.

2015-04-01

Full Text Available Background: The Royal College of Physicians and Surgeons of Canada mandates that community experiences be incorporated into medicine-based specialties.  Presently there is wide variability in community endocrine experiences across Canadian training programs.  This is complicated by the paucity of literature providing guidance on what constitutes a ‘community’ rotation. Method: A modified Delphi technique was used to determine the CanMEDS competencies best taught in a community endocrinology curriculum. The Delphi technique is a qualitative-research method that uses a series of questionnaires sent to a group of experts with controlled feedback provided by the researchers after each survey round.  The experts in this study included endocrinology program directors, community endocrinologists, endocrinology residents and recent endocrinology graduates. Results: Thirty four out of 44 competencies rated by the panel were deemed suitable for a community curriculum.  The experts considered the “Manager” role best taught in the community, while they considered the community least suitable to learn the “Medical Expert” competency. Conclusions: To our knowledge, this is the first time the content of a community-based subspecialty curriculum was determined using the Delphi process in Canada.  These findings suggest that community settings have potential to fill in gaps in residency training in regards to the CanMEDS Manager role.  The results will aid program directors in designing competency-based community endocrinology rotations and competency-based community rotations in other medical subspecialty programs.

Development of these guidelines is mandated by the American Association of Clinical Endocrinologists (AACE) Board of Directors and the American College of Endocrinology (ACE) Board of Trustees and adheres to published AACE protocols for the standardized production of clinical practice guidelines (CPGs). Recommendations are based on diligent review of clinical evidence with transparent incorporation of subjective factors. There are 9 broad clinical questions with 123 recommendation numbers that include 160 specific statements (85 [53.1%] strong [Grade A]; 48 [30.0%] intermediate [Grade B], and 11 [6.9%] weak [Grade C], with 16 [10.0%] based on expert opinion [Grade D]) that build a comprehensive medical care plan for obesity. There were 133 (83.1%) statements based on strong (best evidence level [BEL] 1 = 79 [49.4%]) or intermediate (BEL 2 = 54 [33.7%]) levels of scientific substantiation. There were 34 (23.6%) evidence-based recommendation grades (Grades A-C = 144) that were adjusted based on subjective factors. Among the 1,790 reference citations used in this CPG, 524 (29.3%) were based on strong (evidence level [EL] 1), 605 (33.8%) were based on intermediate (EL 2), and 308 (17.2%) were based on weak (EL 3) scientific studies, with 353 (19.7%) based on reviews and opinions (EL 4). The final recommendations recognize that obesity is a complex, adiposity-based chronic disease, where management targets both weight-related complications and adiposity to improve overall health and quality of life. The detailed evidence-based recommendations allow for nuanced clinical decision-making that addresses real-world medical care of patients with obesity, including screening, diagnosis, evaluation, selection of therapy, treatment goals, and individualization of care. The goal is to facilitate high-quality care of patients with obesity and provide a rational, scientific approach to management that optimizes health outcomes and safety.

Environmental endocrinology of salmon smoltification

Science.gov (United States)

Bjornsson, Bjorn Thrandur; Stefansson, S.O.; McCormick, S.D.

2011-01-01

Smolting is a hormone-driven developmental process that is adaptive for downstream migration and ocean survival and growth in anadromous salmonids. Smolting includes increased salinity tolerance, increased metabolism, downstream migratory and schooling behavior, silvering and darkened fin margins, and olfactory imprinting. These changes are promoted by growth hormone, insulin-like growth factor I, cortisol, thyroid hormones, whereas prolactin is inhibitory. Photoperiod and temperature are critical environmental cues for smolt development, and their relative importance will be critical in determining responses to future climate change. Most of our knowledge of the environmental control and endocrine mediation of smolting is based on laboratory and hatchery studies, yet there is emerging information on fish in the wild that indicates substantial differences. Such differences may arise from differences in environmental stimuli in artificial rearing environments, and may be critical to ocean survival and population sustainability. Endocrine disruptors, acidification and other contaminants can perturb smolt development, resulting in poor survival after seawater entry. ?? 2010.

Endocrinologic complications of cranial irradiation

Brauner, R.; Rappaport, R.

1990-01-01

Cranial irradiation has become one of the leading causes of growth hormone (GH) deficiency. The risk and time of onset of GH deficiency depend mainly on the dose delivered to the hypothalamo-pituitary region: GH deficiency is infrequent after doses under 20 grays and nearly constant after doses above 45 grays. For a given dose, a younger age at the time of irradiation and administration of the dose over a shorter time period increase the risk of GH deficiency. GH secretion can be adequately evaluated using rapid stimulation tests and is usually well correlated with growth, except in patients with radiation-induced precocious puberty or growth delay due to radiation-induced cartilage lesions [fr

For a given dose, a younger age at the time of irradiation and administration of the dose over a shorter time period increase the risk of GH deficiency. GH secretion can be adequately evaluated using rapid stimulation tests and is usually well correlated with growth, except in patients with radiation-induced precocious puberty or growth delay due to radiation-induced cartilage lesions [fr

The endocrinology of food intake.

Many questions must be considered with regard to consuming food, including when to eat, what to eat and how much to eat. Although eating is often thought to be a homeostatic behaviour, little evidence exists to suggest that eating is an automatic response to an acute shortage of energy. Instead, food intake can be considered as an integrated response over a prolonged period of time that maintains the levels of energy stored in adipocytes. When we eat is generally determined by habit, convenience or opportunity rather than need, and meals are preceded by a neurally-controlled coordinated secretion of numerous hormones that prime the digestive system for the anticipated caloric load. How much we eat is determined by satiation hormones that are secreted in response to ingested nutrients, and these signals are in turn modified by adiposity hormones that indicate the fat content of the body. In addition, many nonhomeostatic factors, including stress, learning, palatability and social influences, interact with other controllers of food intake. If a choice of food is available, what we eat is based on pleasure and past experience. This article reviews the hormones that mediate and influence these processes.

Microvascular complications of diabetes mellitus were extensively studied from various points of view. The aim was to elucidate the possible interaction of insulin, glucagon, prolactin, growth hormone, T 3 , and T 4 in the pathogenesis of diabetic retinopathy. Forty patients with diabetic retinopathy (group II) and twenty age-matched controls (group I) were investigated. Plasma levels of both insulin and glucagon were significantly elevated in group II versus group I, whereas other hormones were insignificantly changed. This shows the role that might be played by T 3 , T 4 , growth hormone, and prolactin in the established cases of diabetic retinopathy. (author)

The extrapuerperal secretion of the mammary glands is not a pathological image sui generis, but principally a symptom of a different disease to be detected. On the one hand this procedure must consider differential-diagnostic assessments of the endocrinium and primarily consider disorders of the prolactine metabolism or release. On the other hand, morphologic intraductal processes must be excluded by means of concerted X-ray diagnostics. A clearly defined diagnostic programme permits the concerted treatment of mammary gland secretion according to the causes. Only the systematic progress of the examination offers a sufficient degree of security that fundamental pathologic findings as pituitary adenomas or intraductal carcinomas are not overlooked. (orig.)

The endocrinological complications in β-thalassemia major patients do affect the life quality to a large extend. In this study, the endocrinological complications of 47 β-thalassemia patients, who have been followed-up at our hospital's pediatric hematology department, were evaluated. Out of β-thalassemia major cases included to this study, the 55.3% was male and 44.7% was female. The patients' mean levels of ferritin, whose mean age was 10.0 ± 4.5 years (2-20 years), were 2497 ± 1469 ng/mL (472-8558 ng/mL). At least one endocrinological pathology in 27 out of 47 (57.4%) and more than one endocrinological pathology in 14 out of 47 (29.7%) thalassemia patients were observed. The most frequently observed complication in followed-up cases was vitamin D insufficiency and deficiency (78.2%). The other complications in decreasing order were pubertal failure (41.6%), growth retardation (25.5%), decreased bone-mineral density (22.2%), secondary hyperparathyroidism (11.5%), overt hypothyroidism (4.25%), subclinical hypothyroidism (2.12%), and impaired glucose tolerance (2.12%). There was no statistically significant difference between serum mean ferritin level and endocrin complications (P > .05). Four patients (8.5%) had decreased signal intensity in pituitary magnetic resonance imaging (MRI) but this finding was not associated with ferritin levels (P = .87). MRI parameters were similar between patients with and without gonadal dysfunction. Mean height of the pituitary gland was 4.98 ± 1.1 mm (3-9 mm) and this was similar to those normal values in the literature. Ferritin levels were not correlated with pituitary height (P > .05). Beta thalassemia major, having the potential of leading to multisystemic complications, is a chronic disease that should be treated and followed-up by a multidisciplinary approach. Due to frequently encountered endocrinological complications, beta thalassemic patients should be followed-up regularly by hematology and endocrinology

This study was set up to determine the long term ocular and systemic sequelae in patients with severe congenital toxoplasmosis. Cross sectional and retrospective study of 17 patients with severe congenital toxoplasmosis. In addition to chorioretinitis (100%), the most common abnormal ocular features were optic nerve atrophy (83%), visual acuity of less than 0.1 (85%), strabismus, and microphthalmos. In 50% of cases we observed iridic abnormalities and about 40% developed a cataract. Overt endocrinological disease, diagnosed in five of 15 patients, included panhypopituitarism (n = 2), gonadal failure with dwarfism (n = 1), precocious puberty with dwarfism and thyroid deficiency (n = 1), and diabetes mellitus and thyroid deficiency (n = 1). The observed endocrinological involvement was associated in all cases with obstructive hydrocephalus with a dilated third ventricle and optic nerve atrophy. The recognition of long term ocular, neurological, and endocrinological sequelae of congenital toxoplasmosis is important for medical management of these severely handicapped patients.

The parr-smolt transformation of anadromous salmonids is a suite of behavioral, morphological, and physiological changes that are preparatory for downstream migration and seawater entry. The timing of smolt development varies among species, occurring soon after hatching in pink and chum salmon and after one to several years in Atlantic salmon. In many species the transformation is size dependent and occurs in spring, mediated through photoperiod and temperature cues. Smolt development is stimulated by several hormones including growth hormone, insulin-like growth factor-1, cortisol, and thyroid hormones, whereas prolactin is generally inhibitory. Increased salinity tolerance is one of the most important and tractable changes, and is caused by alteration in the function of the major osmoregulatory organs, the gill, gut, and kidney. Increased abundance of specific ion transporters (Na+/K+-ATPase, Na+/K+/Cl− cotransporter and apical Cl− channel) in gill ionocytes results in increased salt secretory capacity, increased growth and swimming performance in seawater, and higher marine survival.

Although many environmental cues influence reproductive activity, the seasonal breeder responds most strongly to long day length. THE MALE BIRD: Testicular interstitial cells secrete testosterone, which influences reproductive behavior such as territorial aggression and song. Other changes observed in seasonal breeders include testicular hypertrophy and enlargement of the ductus deferens and seminal glomus. THE FEMALE BIRD: Early changes associated with rising estrogen levels in the hen include osteomyelosclerosis and hypercalcemia. Ovulation is then induced by LH, which is followed by eggshell calcification, which is under the control of progesterone. Sources of calcium for shell production include intestinal absorption from the diet, renal control of calcium levels, and mobilization of bone calcium stores. During oviposition, PGF2 alpha and vasotocin stimulate powerful uterine contractions [32] in the presence of calcium. Incubation is associated with falling LH levels and rising prolactin levels. If the hen actually enters reproductive quiescence at this time, then molt will follow. Molt is associated with the total regression of the reproductive tract.

Anorexia nervosa (AN) is a psychiatric disorder characterised by self-induced starvation or a very reduced caloric intake, and frequently by severe life-threatening protein calory malnutrition. Its physiological consequences include amenorrhea, estrogen deficiency and osteoporosis. Osteoporosis may develop as a consequence of a lack of estrogens, low calcium or vitamin D intake, hypercortisolemia or the duration of the illness. The aim of this study was to identify the best endocrinological and nutritional indicators of bone density. The study involved 49 young females with AN and malnutrition and 24 age-matched normal controls in whom AN had been excluded on the basis of a clinical evaluation using DSM IV criteria. We studied bone density in early osteopenia, a condition in which the potential risk of fractures is certainly high and traditionally related to a variety of endocrinological and nutritional factors. Bone density was significantly lower in the AN than the control group in all of the examined bone districts: bone mineral density (BMD) spine 0.89 +/- 0.19 vs 1.27 +/- 0.2 (pexercise, urinary free cortisol osteocalcin and type I collagen-telopeptide (NTX) did not significantly correlate with the degree of osteopenia. Our data suggest the importance of nutritional factors (particularly lean body mass and BMI) in determining bone mass, and the relatively limited importance of endocrinological factors with the exception of the duration of amenorrhea as an indirect indicator of endocrinological status.

The Need for Open-access, Structured Data in Endocrine Research

Full Text Available Data sharing has become a ‘hot topic’ for university librarians, faculty, and research centers, with particular focus within biomedical science, to prevent duplication of effort, promote scientific integrity, and permit the creation of new data sets when data from multiple sources are combined. However, access to and sharing of scientific data require substantial effort and investment to define specifications and generate requisite resources. Studies from well-designed and well-conducted medical registries can provide a real-world view of clinical practice, patient outcomes, safety, and may strengthen evidence-based decision making processes. At present, if cardiovascular data management has been sufficiently documented with data exchange in all clinical research, clinical registry, and patient care environments, including all electronic health records. It is nevertheless still necessary to create a database for endocrinology, particularly in light of new medical research that have blurred the concept of endocrinology as a discipline of basic science. The aim of this paper is to conceive datasets in endocrinology research and facilitate the exchange of data across studies and to promote interoperability between different research centres.

Since the first position statement on diabetes and cardiovascular prevention published in 2014 by the Brazilian Diabetes Society, the current view on primary and secondary prevention in diabetes has evolved as a result of new approaches on cardiovascular risk stratification, new cholesterol lowering drugs, and new anti-hyperglycemic drugs. Importantly, a pattern of risk heterogeneity has emerged, showing that not all diabetic patients are at high or very high risk. In fact, most younger patients who have no overt cardiovascular risk factors may be more adequately classified as being at intermediate or even low cardiovascular risk. Thus, there is a need for cardiovascular risk stratification in patients with diabetes. The present panel reviews the best current evidence and proposes a practical risk-based approach on treatment for patients with diabetes. The Brazilian Diabetes Society, the Brazilian Society of Cardiology, and the Brazilian Endocrinology and Metabolism Society gathered to form an expert panel including 28 cardiologists and endocrinologists to review the best available evidence and to draft up-to-date an evidence-based guideline with practical recommendations for risk stratification and prevention of cardiovascular disease in diabetes. The guideline includes 59 recommendations covering: (1) the impact of new anti-hyperglycemic drugs and new lipid lowering drugs on cardiovascular risk; (2) a guide to statin use, including new definitions of LDL-cholesterol and in non-HDL-cholesterol targets; (3) evaluation of silent myocardial ischemia and subclinical atherosclerosis in patients with diabetes; (4) hypertension treatment; and (5) the use of antiplatelet therapy. Diabetes is a heterogeneous disease. Although cardiovascular risk is increased in most patients, those without risk factors or evidence of sub-clinical atherosclerosis are at a lower risk. Optimal management must rely on an approach that will cover both cardiovascular disease prevention in

The metabolome, although very dynamic, is sufficiently stable to provide specific quantitative traits related to health and disease. Metabolomics requires balanced use of state-of-the-art study design, chemical analytics, biostatistics, and bioinformatics to deliver meaningful answers to contemporary questions in human disease research. The technology is now frequently employed for biomarker discovery and for elucidating the mechanisms underlying endocrine-related diseases. Metabolomics has also enriched genome-wide association studies (GWAS) in this area by providing functional data. The contributions of rare genetic variants to metabolome variance and to the human phenotype have been underestimated until now. Copyright © 2017 Elsevier Ltd. All rights reserved.

Endocrinologic control of normal canine ovarian function.

Concannon, P W

In dogs, the termination of the 3-10-month obligate anoestrus involves selection of a cohort of LH-sensitive follicles, presumably from a wave of dominant small antral follicles that would otherwise undergo atresia. The number and size of such follicles appears to increase, especially during the last 50 days of anoestrus when the already elevated concentrations of FSH become further elevated. The final selection and eventual terminal development of these follicles is caused by an increased frequency of high-amplitude LH pulses at the end of anoestrus. Concomitant increases in FSH are typically small or negligible. High concentrations of FSH in anoestrus are likely to be important in maintaining, if not stimulating, overlapping waves of dominant follicles throughout anoestrus, their expression of aromatase activity and basal oestradiol secretion sufficient to suppress LH by negative feedback. An attractive hypothesis is that late anoestrus increases in LH-stimulate synthesis of precursor androgen for already available FSH-dependent aromatase. After 7 or more days of elevated LH, and perhaps 2-5 days of semi-autonomous growth, with maximal oestradiol production reached, follicle capacity to further increase oestradiol becomes limited and excess progesterone becomes increasingly secreted. The pre-ovulatory LH surge and oestrus onset are then triggered - often synchronously and in concert with the terminal maturation of the follicles - by central effects of the large decrease in the oestrogen to progestin ratio. Follicular endocrine and paracrine events during and following the LH surge are likely similar to those reported for other species. The prolonged luteal phase lengths of 55-75 days in non-pregnant bitches bracket the 64 +/- 1 day in pregnancy and represent a genetically programmed luteal cell lifespan approximating gestation length as occurs in the luteal phase of hysterectomized animals of most polyoestrous artiodactyls and rodents. The 30-40-day slow regression after day 20 to 30 involves periodic cell death, diminution in cell size, low levels of apoptosis and minimal or modest involvement of endogenous prostaglandin F (PGF) production. The canine corpus luteum (CL) is dependent on both LH and prolactin as stimulating luteotrophins by day 15, and as required luteotrophins by days 20-25, if not earlier. Thereafter, both luteotrophins likely have cellular mechanisms of action similar to those reported for other species. Progesterone secretion during pregnancy is greatly enhanced by characteristic, and probably relaxin-stimulated, increases in prolactin concentration starting at or after day 25, and persisting to term. Near term, foetoplacental maturation results in the placental release of large, luteolytic amounts of PGF for 1-2 days pre-partum. Pre-partum luteolysis, like that induced by exogenous prostaglandin, likely involves a cascade enhanced by the removal of progesterone inhibition of PGF release and some degree of intra-luteal PGF synthesis. That a likely twofold or greater increase in progesterone production by the CL of pregnancy does not result in significantly higher serum progesterone than in non-pregnant metoestrus relates to several biological changes, including a large increase in plasma volume of distribution, increased metabolism of progesterone by increased uterine, placental and mammary masses and increased liver clearance and excretion of progesterone and progesterone metabolite. Anoestrus length and ovarian cycle intervals, variable within and among bitches, are likely affected by neuroendocrine components of an endogenous circannual cycle, albeit only photo-entrained in the Basenji breed. This may be modified by the prior luteal phase, exposure to oestrus female pheromones and as yet unknown mechanisms that likely operate via inhibitory opioidergic and/or stimulatory dopaminergic hypothalamic pathways affecting late anoestrus increases in LH.

Late neuro endocrinological sequelae of radiation therapy

International Nuclear Information System (INIS)

Bieri, S.; Bernier, J.; Sklar, C.; Constine, L.

1997-01-01

When the hypothalamic-pituitary axis (HPA) is included in the treatment field in children and adults, a variety of neuroendocrine disturbances are more common than has been appreciated in the past. Clinical damage to the pituitary and thyroid glands usually occurs months to years after treatment, and is preceded by a long subclinical phase. Primary brain tumors represent the largest group of malignant solid tumors in children. The survival rates of 50 reported in the literature are achieved at the expense of late occurring effects. Radiation-induced abnormalities are generally dose-dependent. Growth hormone deficiency and premature sexual development can occur at doses as low as 18 Gy in conventional fractionation, and is the most common neuroendocrine problem in children. In patients treated with > 40 Gy on the HPA, deficiency of gonadotropins, thyroid stimulation hormone, and adrenocorticotropin (> 50 Gy), hyperprolactinemia can be seen, especially among young women. Most neuroendocrine disturbances that develop as a result of HPA can be treated efficiently, provided that an early detection of these endocrine dysfunctions abnormalities is done. (authors)

Reproductive endocrinology of wild, long-lived raptors.

The last decades have witnessed a surge of studies analyzing the role of sex hormones on the behavior and ecology of wild bird populations, allowing a more integrated view of the evolution of avian physiology and life histories. Despite a marked progress, field studies show a considerable bias towards research on specific phylogenetic groups, neglecting a significant fraction of the class Aves. Here we analysed changes in the circulating levels of sex steroids in relation to reproductive behaviour in wild black kites (Milvus migrans), a long-lived and socially monogamous Accipitridae raptor. Males and females displayed a single seasonal peak of circulating testosterone (males) and estradiol (females) during pre-laying and laying. Absolute male testosterone levels were low even at the seasonal maximum and remained below detection limits in females. The latter results supports the idea that avian species establishing long-term pair bonds require lower amounts of circulating androgens for reproduction. Circulating progesterone showed a single seasonal peak in females and males, but their timing (during Incubation and Post-brooding respectively) did not overlap. The fact that females black kites perform the majority of incubation and males provide the majority of care to fledglings suggests that progesterone is involved in the expression of parental behaviors.

In this setting, in recent years, there has been an exponential rise in the number of bariatric procedures, with approximately half of them performed in women of childbearing age, and a remarkable surge in the number of women who become pregnant after having undergone bariatric surgery (BS. These procedures entail the risk of nutritional deficiencies, and nutrition is a crucial aspect during pregnancy. Therefore, knowledge and awareness of the consequences of these techniques on maternal and fetal outcomes is essential. Current evidence suggests a better overall obstetric outcome after BS, in comparison to morbid obese women managed conservatively, with a reduction in the prevalence of gestational diabetes mellitus, pregnancy-associated hypertensive disorders, macrosomia, and congenital defects. However, the risk of potential maternal nutritional deficiencies and newborns small for gestational age cannot be overlooked. Results concerning the incidence of preterm delivery and the number of C-sections are less consistent. In this paper, we review the updated evidence regarding the impact of BS on pregnancy.

To explore the characteristics of diabetes mellitus in adults with Turner syndrome. Observational study consisting of a prospective phase after the access of adults with Turner syndrome to the Endocrinology Unit (median period of follow-up 15.6, interquartile range: 12.0-24.5 months) and a retrospective collection of data from the diagnosis of Turner syndrome until the time of access to the Endocrinology Unit. A total of 113 Italian Turner syndrome patients were included in the study. During the prospective phase of the study, each patient underwent physical examination, fasting blood sampling, and an oral glucose tolerance test on a yearly basis. Oral glucose tolerance test was used to perform the diagnosis of diabetes mellitus. Before access to the Endocrinology Unit, diabetes mellitus was diagnosed in two Turner syndrome patients. Another five cases of diabetes mellitus were diagnosed at the first access to the Endocrinology Unit, whereas seven new cases of diabetes mellitus were diagnosed during the prospective phase of the study. At the diagnosis of diabetes mellitus, only one patient had fasting glucose above 126 mg/dL, and only two had an HbA1c value >6.5% (48 mmol/mol). When compared to normo-glucose tolerant patients, the diabetic patients had a significantly lower insulin-to-glucose ratio at 30 and 60 min of the oral glucose tolerance test. In the regression analyses, only age was associated with the development of diabetes mellitus. This study confirms that diabetes mellitus is frequent in Turner syndrome and suggests that it is specific to the syndrome. In addition, this study demonstrates that oral glucose tolerance test is a more sensitive test than HbA1c for the diagnosis of diabetes mellitus in Turner syndrome.

Full Text Available Endocrinologists contribute to the care of sizable populations with diabetes, thyroid disorders, obesity, metabolic syndrome, osteoporosis, dyslipidemia, pituitary disease, adrenal disease, male and female reproductive disorders and menopausal women. In addition, the trend of prevalences of endocrine and metabolic disorders show that these diseases are highly prevalent, with none becoming less common; on the contrary, diabetes and obesity are the great epidemics of the third millennium. Based on the number of hospital beds, required office-based services, trend of endocrinology diseases, current prevalence of this disease, an estimated 860 endocrinologist are needed while at present there are only 146 adult endocrinologists are practicing. Efforts are urgently needed to find solutions for this gap in the endocrinology workforce if quality services is to be offered.

To determine the number of adult clinic patients seen for type 2 diabetes mellitus (T2DM) at an academic medical center and to examine characteristics of those who had or had not registered for a web portal. Electronic records were reviewed to identify web portal registration by patients treated for T2DM by age, sex, race and Hispanic ethnicity, and service (General Internal Medicine, Endocrinology). A total of 1,401 patients with T2DM were seen in General Internal Medicine and Endocrinology outpatient clinics. Less than one third (32%) had registered for the web portal. Women were more likely to have registered for the web portal than men [odds ratio (OR) =1.25; 95% CI, 0.99-1.57; Pweb portal, along with those who were 56 to 60 and >66 years of age. In multivariate analysis, a statistically significant association was observed between web portal registration and General Internal Medicine clinic vs . Endocrinology clinic (OR =2.96, P18-25 years, male sex (adjusted OR =0.71, P=0.006), and Black race (OR =0.33, P<0.001). Additional research is needed to identify portal design features that improve glycemic control and interventions that will increase use of patient portals, especially among Black patients with T2DM and those with low health literacy or computer literacy.

Nutrition, endocrinology, and body composition during space flight

Lane, H. W.; Gretebeck, R. J.; Smith, S. M.

1998-01-01

Space flight induces endocrine changes that perturb metabolism. This altered metabolism affects both the astronauts' body composition and the nutritional requirements necessary to maintain their health. During the last 25 years, a combination of studies conducted on Skylab (the first U.S. space laboratory), U.S. Shuttle flights, and Soviet and Russian flights provides a range of data from which general conclusions about energy and protein requirements can be drawn. We have reviewed the endocrine data from those studies and related it to changes in body composition. From these data it appears that protein and energy intake of astronauts are similar to those on Earth. However, a combination of measures, including exercise, appropriate diet, and, potentially, drugs, is required to provide the muscle health needed for long duration space flight.

Skin abnormality and hairloss: the reproductive endocrinological viewpoint

Directory of Open Access Journals (Sweden)

Ali Baziad

2004-12-01

Full Text Available Excessive androgen production may cause changes in female skin, such as hirsutism and acne. The administration of antiadrogenic hormone such as cyproteron acetate, may eliminate the hyperandrogenic effect on the skin. Hairloss may also caused either by hyper-androgenemia or by low estrogen level. The administration of either antiandrogen or estrogen may reduce hairloss. Virilization, which includes excessive growth of hair and clitoris enlargement, deepened voice, muscle hypertrophy and mammary hypoplasia are also associated with hyperandrogenemia. Antiandrogen treatment could eliminate these impacts of virilization. In contrast, cellulite was supected to be due to androgen deficiency, and the use of topical testosterone could eliminate it. It is concluded that skin and/or hairloss are associated with hormonal changes in women. The treatment with antiandrogenic hormones may reduce or cure these abnormalities.

Lesions of hypothalamus or adjacent brain structures by the craniopharyngioma (CP) and/or its treatment, as well as changes in orexigenic and anorexigenic hormones, are possible pathogenic factors for the obesity observed in CP patients. This study assessed anthropometric measurements, food intake, and biochemical markers of CP patients. Weight, height, skinfold thicknesses, circumferences, body composition, food intake evaluation, basal glucose, lipids, insulin, ghrelin, PYY, and HOMA-IR calculation were obtained from CP children (n = 10, 4F, aged 12 ± 4.2yr) and CP adults (n = 27,13F aged 42 ± 13 yr) and from 32 gender and age matched controls. Overweight/obesity was observed in 51.4% of the patients at the diagnosis and increased to 86.5% at the time of the study. Obesity was more frequent in patients with grade 2 hypothalamic involvement. Most anthropometric measurements were similar in patients and controls. Caloric intake was lower in CP adults, without difference between children. Lipid intake was higher in CP patients. Carbohydrate and protein intakes were lower in CP children, with no difference between adult groups. There were no differences in micronutrients intake as well as in insulin and PYY levels, and HOMA-IR between patients and controls. HDL-c was lower in CP adults and ghrelin higher in CP children. There is a high rate of overweight/obesity in CP patients at the diagnosis and throughout the follow-up period. Obesity was associated with degree of hypothalamic involvement but not with caloric intake. Obesity and a lipid rich diet may have contributed to the dyslipidemia observed in CP patients.

Gynecological problems are one of the most frequent somatic complications of eating disorders. The purpose of the present study was to assess the role of improper eating habits causing menstrual disturbances, anovulation and related hormonal changes. Latent bulimia nervosa is in the focus of attention since amenorrhea is considered as a diagnostic criterion of anorexia nervosa. Subjects of the BITE (Bulimia Investigation Test, Edinburgh) test were infertile patients (n = 34) of the gynecological outpatient departments after medical examination, blood-test (LH, FSH, androstenedione, DHEAS, progesterone, testosterone, SHBG, prolactin) and ultrasonic examination (uterus and ovaries). Symptoms and severity subscales of the BITE test and body mass index (BMI) were close correlation (p = 0.003, p = 0.033). In comparison with previous results, EDNOS (Eating Disorders Not Otherwise Specified) prevalence was 48%. Of hormonal changes, low LH and FSH levels (6/6) and hyperandrogenism (5/6) were significant in patients with subclinical eating disorders (n = 6) by infertile women as compared with the "normal" infertile group (n = 18; 7/18, 8/18). The recent results suggests that unsatisfactory nutrition (bulimic binges, "crash diet") is as relevant in hormonal dysfunction, menstrual disturbances and infertility as pathologically low weight in anorexia nervosa. Excessive application of contraceptives in therapy has to be taken into consideration.

Endocrinology and the brain: corticotropin-releasing hormone signaling.

Corticotropin-releasing hormone (CRH) is a key player of basal and stress-activated responses in the hypothalamic-pituitary-adrenal axis (HPA) and in extrahypothalamic circuits, where it functions as a neuromodulator to orchestrate humoral and behavioral adaptive responses to stress. This review describes molecular components and cellular mechanisms involved in CRH signaling downstream of its G protein-coupled receptors (GPCRs) CRHR1 and CRHR2 and summarizes recent findings that challenge the classical view of GPCR signaling and impact on our understanding of CRHRs function. Special emphasis is placed on recent studies of CRH signaling that revealed new mechanistic aspects of cAMP generation and ERK1/2 activation in physiologically relevant contexts of the neurohormone action. In addition, we present an overview of the pathophysiological role of the CRH system, which highlights the need for a precise definition of CRHRs signaling at molecular level to identify novel targets for pharmacological intervention in neuroendocrine tissues and specific brain areas involved in CRH-related disorders. © 2017 The authors.

Endocrinology of pregnancy in the dog: a review.

Science.gov (United States)

Verstegen-Onclin, K; Verstegen, J

2008-08-01

Pregnancy regulation in the dog is not yet fully elucidated. Since plasma progesterone concentrations are similar in pregnant versus non-pregnant animals, it is a poor reflection on CL function and progesterone metabolism. Increased progesterone secretion by the CL in pregnant animals follows implantation and relaxin secretion by the feto-placental units. Progesterone is absolutely required to maintain pregnancy and no placental sources of progesterone have been identified. Pregnancy can be artificially maintained by progesterone administration. Prolactin secretion appears to be increased in response to the increase in relaxin production and occurs independent of estrogen production by the CL. The respective roles of LH, FSH and prolactin are still unclear, with considerable conflicting evidence among studies. However, it appears that prolactin is absolutely required, whereas LH is either permissive or facilitates CL function during pregnancy. Pre-implantation events are still poorly defined in the bitch, and no embryonic factors have been isolated or purified, preventing early pregnancy diagnosis. Parturition occurs following luteolysis, which results from the release of prostaglandin F(2alpha), which begins 36h prepartum in a process similar to that observed in other species. The role of estrogens at the time of parturition remains undefined.

Genetics of Common Endocrine Disease: The Present and the Future.

Science.gov (United States)

Goodarzi, Mark O

2016-03-01

In honor of the 75th issue of the Journal of Clinical Endocrinology and Metabolism, the author was invited to present his perspectives on genetics in human endocrinology. This paper reviews what the field has achieved in the genetics of common endocrine disease, and offers predictions on where the field will move in the future and its impact on endocrine clinical practice. The October 2015 data release of the National Human Genome Research Institute-European Bioinformatics Institute (NHGRI-EBI) Catalog of Published Genome-wide Association Studies was queried regarding endocrinologic diseases and traits. PubMed searches were focused on genetic prediction of disease, genetic findings and drug targets, functional interrogation of genetic loci, use of genetics to subtype disease, missing heritability, systems genomics, and higher order chromatin structures as regulators of gene function. Nearly a quarter of genome wide association study findings concern endocrinologic diseases and traits. While these findings have not yet dramatically altered clinical care, genetics will have a major impact by providing the drug targets of tomorrow, facilitated by experimental and bioinformatic advances that will shorten the time from gene discovery to drug development. Use of genetic findings to subtype common endocrine disease will allow more precise prevention and treatment efforts. Future advances will allow us to move away from the common view of DNA as a string of letters, allowing exploration of higher order structure that likely explains much "missing heritability." The future will see a greater role of genetics at the bedside, with genetic epidemiologic discoveries leading not only to new treatments of endocrine disease, but also helping us prescribe the right drug to the right patients by allowing subclassification of common heterogeneous endocrine conditions. Future technological breakthroughs will reveal the heritable mysteries hidden in chromatin structure, leading to a

Reliability of magnetic resonance imaging for the detection of hypopituitarism in children with optic nerve hypoplasia.

It is essential to identify hypopituitarism in children with optic nerve hypoplasia (ONH) because they are at risk for developmental delay, seizures, or death. The purpose of this study is to determine the reliability of neurohypophyseal abnormalities on magnetic resonance imaging (MRI) for the detection of hypopituitarism in children with ONH. Cross-sectional study. One hundred one children with clinical ONH who underwent MRI of the brain and orbits and a detailed pediatric endocrinologic evaluation. Magnetic resonance imaging studies were performed on 1.5-Tesla scanners. The imaging protocol included sagittal T1-weighted images, axial fast fluid-attenuated inversion-recovery/T2-weighted images, and diffusion-weighted images of the brain. Orbital imaging included fat-saturated axial and coronal images and high-resolution axial T2-weighted images. The MRI studies were reviewed by 2 pediatric neuroradiologists for optic nerve hypoplasia, absent or ectopic posterior pituitary, absent pituitary infundibulum, absent septum pellucidum, migration anomalies, and hemispheric injury. Medical records were reviewed for clinical examination findings and endocrinologic status. All patients underwent a clinical evaluation by a pediatric endocrinologist and a standardized panel of serologic testing that included serum insulin-like growth factor-1, insulin-like growth factor binding protein-3, prolactin, cortisol, adrenocorticotropic hormone, thyroid-stimulating hormone, and free thyroxine levels. Radiologists were masked to patients' endocrinologic status and funduscopic findings. Sensitivity and specificity of MRI findings for the detection of hypopituitarism. Neurohypophyseal abnormalities, including absent pituitary infundibulum, ectopic posterior pituitary bright spot, and absent posterior pituitary bright spot, occurred in 33 children. Magnetic resonance imaging disclosed neurohypophyseal abnormalities in 27 of the 28 children with hypopituitarism (sensitivity, 96%). A�

Full Text Available Daphne SL Gardner1, E Shyong Tai21Department of Endocrinology, Singapore General Hospital, 2Department of Endocrinology, National University Hospital, SingaporeAbstract: Maturity onset diabetes of the young (MODY is a heterogeneous group of disorders that result in ß-cell dysfunction. It is rare, accounting for just 1%–2% of all diabetes. It is often misdiagnosed as type 1 or type 2 diabetes, as it is often difficult to distinguish MODY from these two forms. However, diagnosis allows appropriate individualized care, depending on the genetic etiology, and allows prognostication in family members. In this review, we discuss features of the common causes of MODY, as well as the treatment and diagnosis of MODY.Keywords: type 1 diabetes, type 2 diabetes, HNF1A, HNF4A, HNF1B, GCK

Twenty-four cases of pituitary adenoma, 13 males and 11 females with the age ranging from 11 to 65 years, received radiation therapy(RT) on the pituitary area with 6MV linear accelerator during past 25 months at the Division of Radiation Therapy, Kangnam St. Mary Hospital, Catholic Medical College. Of 24 case of RT, 20 were postoperative and 4 primary. To evaluate the effect of RT, we analyzed the alteration of the endocrinological tests, neurologic abnormalities, major clinical symptoms, endocrinological changes and improvement in visual problems after RT. The results were as follows ; 1. Major clinical symptoms were headache, visual defects, diabetes insipidus, hypogonadisms and general weakness in decreasing order of frequency. 2. All but the one with Nelson syndrome showed abnormal neuroradiologic changes in the sella turcica with an invasive tumor mass around supra and para-sellar area. 3. Endocrinological classifications of the patient were 11 prolactinoma, 4 growth hormonesecreting tumors, 3 ACTH-secreting tumors consisting of one Cushing disease and two Nelson syndrome, and 6 nonfunctioning tumors. 4. Eleven of 14 patients, visual problems were improved after treatment but remaining 3 were unchanged. 5. Seven of 11 prolactinomas returned to normal hormonal level after postoperative and primary RT and 3 patients are being treated with bromocriptine (BMCP) but on lost case. 6. Two of 4 growth hormone-secreting tumor returned to normal level after RT but the remaining 2 are being treated with BMCP, as well

[Cornelia de Lange Syndrome and multiple hormonal deficiency, an unusual association. Clinical case].

Science.gov (United States)

Mora-Bautista, Víctor M; Mendoza-Rojas, Víctor; Contreras-García, Gustavo A

2017-06-01

Cornelia de Lange syndrome is a genetic disease characterized by distinctive facial features, failure to thrive, microcephaly and several malformations associated. Its main endocrinological features are anomalies of the genitalia. We present a 13-year-old boy, who suffered from complicated aspiration pneumonia and showed Cornelia de Lange syndrome phenotype, with global developmental delay, suction-swallowing abnormalities, short stature and abnormal genitalia associated. His bone age was delayed, so he underwent full endocrinological panel. Central hypothyroidism, growth hormone deficiency and low luteinizing hormone-follicle-stimulating hormone levels were observed and multiple pituitary hormone deficiencies diagnosis was made. Basal cortisol, adrenocorticotropic hormone and prolactin levels were normal. He received thyroid hormonal substitution. Multiple pituitary hormone deficiencies are an unusual feature of De Lange syndrome. We suggest evaluating all different endocrine axes in these patients. Sociedad Argentina de Pediatría.

Although theory suggests a link between social anxiety and social dominance, direct empirical evidence for this link is limited. The present experiment tested the hypothesis that socially anxious individuals, particularly men, would respond to a social-dominance threat by exhibiting decrements in their testosterone levels, an endocrinological change that typically reflects pronounced social submission in humans and other animals. Participants were randomly assigned to either win or lose a rigged face-to-face competition with a confederate. Although no zero-order relationship between social anxiety and level of testosterone was observed, testosterone levels showed a pronounced drop among socially anxious men who lost the competition. No significant changes were observed in nonanxious men or in women. This research provides novel insight into the nature and consequences of social anxiety, and also illustrates the utility of integrating social psychological theory with endocrinological approaches to psychological science. PMID:18816282

To provide practical recommendations for evaluation and follow-up of patients with normocalcemic primary hyperparathyroidism. Members of the Bone Metabolism Working Group of the Spanish Society of Endocrinology. A systematic search was made in MEDLINE (PubMed), using the terms normocalcemic primary hyperparathyroidism and primary hyperparathyroidism, for articles in English published before 22 November 2012. Literature was reviewed by 2 members of the Bone Metabolism Working Group of the Spanish Society of Endocrinology, and after development of recommendations, the manuscript was reviewed by all other members of the Group, and their suggestions were incorporated. The document provides practical recommendations for evaluation and follow-up of patients with normocalcemic primary hyperparathyroidism. There is however little evidence available about different aspects of this disease, mainly progression rate and clinical impact. More data are therefore needed before definite recommendations may be made. Copyright © 2012 SEEN. Published by Elsevier Espana. All rights reserved.

[Changes in muscle tissue in hypothyroidism].

Science.gov (United States)

Jiskra, J

2001-09-01

This article offers a synopsis of detailed analysis of the functional and structural changes in muscle tissue in manifest and subclinical hypothyroidism. There is a brief overview of the division between mypathy and myositis, with emphasis on endocrinological and metabolic disorders. The necessity of endocrinological examination in each case of myopathy the etiology of which is indefinite is stressed, and this especially before the instigation of non-specific immunosuppressive treatment (e.g., corticosteroids) as this treatment has the risk of undesirable side-effects. In conclusion, it emphasises the negative influence of the nexus of hypothyroidism and the administering of a hypolipidemic in tandem on muscle tissue, as in rare cases this can lead to the disintegration of muscle tissue, i.e., rhabdomyolysis. The administering of hypolipidemic drugs to patients with hypothyroidism is indicated only in those cases where persists hyperlipoproteinemia after the normalisation of the thyroid function by substitutional treatment.

Endocrinology of anorexia nervosa in young people: recent insights

Science.gov (United States)

Singhal, Vibha; Misra, Madhusmita; Klibanski, Anne

2014-01-01

Purpose of review Anorexia nervosa is among the most prevalent chronic medical conditions in young adults. It has acute as well as long-term consequences, some of which, such as low bone mineral density (BMD), are not completely reversible even after weight restoration. This review discusses our current understanding of endocrine consequences of anorexia nervosa. Recent findings Anorexia nervosa is characterized by changes in multiple neuroendocrine axes including acquired hypogonadotropic hypogonadism, growth hormone resistance with low insulin-like growth factor-1 (likely mediated by fibroblast growth factor-1), relative hypercortisolemia, alterations in adipokines such as leptin, adiponectin and resistin, and gut peptides including ghrelin, PYY and amylin. These changes in turn contribute to low BMD. Studies in anorexia nervosa have demonstrated abnormalities in bone microarchitecture and strength, and an association between increased marrow fat and decreased BMD. One study in adolescents reported an improvement in BMD following physiologic estrogen replacement, and another in adults demonstrated improved BMD following risedronate administration. Brown adipose tissue is reduced in anorexia nervosa, consistent with an adaptive response to the energy deficit state. Summary Anorexia nervosa is associated with widespread physiologic adaptations to the underlying state of undernutrition. Hormonal changes in anorexia nervosa affect BMD adversely. Further investigation is underway to optimize therapeutic strategies for low BMD. PMID:24275621

Recent advances in the endocrinology of the sebaceous gland.

Science.gov (United States)

Szöllősi, Attila G; Oláh, Attila; Bíró, Tamás; Tóth, Balázs István

2017-01-01

The sebaceous gland, long considered an evolutionary relic with little-to-no physiological relevance in humans, has emerged in recent decades as a key orchestrator and contributor to many cutaneous functions. In addition to the classical physico-chemical barrier function of the skin against constant environmental challenges, a more novel, neuro-immune modulatory role has also emerged. As part of the complex intercellular communication network of the integumentary system, the sebaceous gland acts as a "relay station" in the skin for many endocrine factors. This review aims to offer a comprehensive overview of endocrine effects and subsequent interactions on this much maligned mini-organ.

This is a descriptive review of several mechanisms that can explain the IR among women with PCOS, other risk factors for the development of diabetes, and the screening methods used for the detection of glucose intolerance in women with PCOS. Few mechanisms can explain IR in women with PCOS such as obesity, insulin receptor signaling defects, and inhibition of insulin-mediated glucose uptake in adipocytes. Women with PCOS have additional risk factors for the development of glucose intolerance such as family history of diabetes, use of oral contraceptives, anovulation, and age. The Androgen Society in 2007 and the Endocrine Society in 2013 recommended using oral glucose tolerance test as a screening tool for abnormal glucose tolerance in all women with PCOS. The approach to detection of glucose intolerance among women with PCOS varies among health care providers. Large prospective studies are still needed for the development of guidelines with strong evidence. When assessing risk of future diabetes in women with PCOS, it is important to take into account the method used for screening as well as other risk factors that these women might have.
