Multi-Branch Attention Learning for Bone Age Assessment with Ambiguous Label.

Bone age assessment (BAA) is a typical clinical technique for diagnosing endocrine and metabolic diseases in children's development. Existing deep learning-based automatic BAA models are trained on the Radiological Society of North America dataset (RSNA) from Western populations. However, due to the difference in developmental process and BAA standards between Eastern and Western children, these models cannot be applied to bone age prediction in Eastern populations. To address this issue, this paper collects a bone age dataset based on the East Asian populations for model training. Nevertheless, it is laborious and difficult to obtain enough X-ray images with accurate labels. In this paper, we employ ambiguous labels from radiology reports and transform them into Gaussian distribution labels of different amplitudes. Furthermore, we propose multi-branch attention learning with ambiguous labels network (MAAL-Net). MAAL-Net consists of a hand object location module and an attention part extraction module to discover the informative regions of interest (ROIs) based only on image-level labels. Extensive experiments on both the RSNA dataset and the China Bone Age (CNBA) dataset demonstrate that our method achieves competitive results with the state-of-the-arts, and performs on par with experienced physicians in children's BAA tasks.

One year of the pandemic - how European endocrinologists responded to the crisis: a statement from the European Society of Endocrinology.

Changes that COVID-19 induced in endocrine daily practice as well as the role of endocrine and metabolic comorbidities in COVID-19 outcomes were among the striking features of this last year. The aim of this statement is to illustrate the major characteristics of the response of European endocrinologists to the pandemic including the disclosure of the endocrine phenotype of COVID-19 with diabetes, obesity and hypovitaminosis D playing a key role in this clinical setting with its huge implication for the prevention and management of the disease. The role of the European Society of Endocrinology (ESE) as a reference point of the endocrine community during the pandemic will also be highlighted, including the refocusing of its educational and advocacy activities.

EndoERN patient survey on their perception of health care experience and of unmet needs for rare endocrine diseases.

Patients' perceptions on quality of care and gaps in diagnosis/management of rare endocrine diseases (RED) were collected in a 21-item questionnaire, answered on-line in the patients' language. There were 598 (66% females) responses from 29 countries reflecting pituitary, adrenal, thyroid, parathyroid, gonadal, genetic and autoimmune diseases. While in 36% a diagnosis was made in <1 year, in 28% it took >5 years. In 64% it took 2-7 professionals for a correct diagnosis, after which in >50% a specialist/specific treatment was available within 1 month; 60% were satisfied with current treatment. Most (59-67%) would have liked access to psychological support, social worker, dietician or physiotherapist/rehabilitation specialists. Half were satisfied with information received, treatment and health care follow-up; 87% contacted patient/support groups; 78% agreed that "The personal limitations related to the disease, impact on my everyday quality of life". Conclusion: Diagnostic delay in RED is still unsatisfactory in Europe, as well as specific needs impacting QoL.

Development of an index of complexity for outpatient endocrinology and nutrition clinics. / Desarrollo de un índice de complejidad en consultas externas de Endocrinología y Nutrición.

INTRODUCTION: The tools for analyzing the case-mix in outpatient clinics are scarce few and unsatisfactory. The objective of this study conducted by Sociedad Castellano Manchega de Endocrinología, Nutrición y Diabetes (SCAMEND) was to develop a tool that allows for analyzing the case-mix in outpatient endocrinology and nutrition clinics, considering bearing in mind the complexity of the conditions seen. MATERIAL AND METHODS: Using the Delphi method, the SCAMEND index of complexity in outpatient endocrinology and nutrition clinics (ISCCE-EyN) was developed by endocrinologists in two rounds, comparing the complexity of each condition being compared with that of a review visit of primary hypothyroidism. RESULTS: The first visits were considered more complex than the subsequent visits. Non-neoplastic thyroid disease and uncomplicated overweight/obesity were considered as the least complex diseases, while metabolic diseases, multiple endocrine neoplasia syndromes, and adrenal carcinoma were considered as the most complex. The degree of agreement was high in most of the diseases analyzed. CONCLUSIONS: This tool allows for analyzing the case-mix in outpatient endocrinology and nutrition clinics, based on the inherent complexity of the disease of the patient is reported. This tool may be used for comparisons between centers, to better allocate resources within a given service, or for self-evaluation.

Functional and endocrine-metabolic oligomenorrhea: proposal of a new diagnostic assessment tool for differential diagnosis in adolescence.

Background To develop a diagnostic assessment tool, using clinical, biochemical and sonographic markers, to help clinicians in the differential diagnosis of functional oligomenorrhea (FO) and endocrine-metabolic oligomenorrhea (EMO). Methods Sixty-two adolescents with oligomenorrhea without evident hormonal imbalances or severe energy deficit were selected. They were divided into two groups (EMO and FO) and they all underwent the following assessment: physical examination (height, weight, presence of hirsutism or acne), blood exams and transabdominal ultrasonography. The biochemical markers included: hemoglobin, thyrotropin stimulating hormone (TSH), prolactin (PRL), follicle stimulating hormone (FSH), luteinizing hormone (LH), free (FT) and total testosterone (TT), androstenedione (A), dehydroepiandrosterone sulfate (DHEAS) and sex hormone binding globulin (SHBG). Uterine and ovarian volume, ovarian morphology, endometrial thickness and pulsatility index (PI) of uterine arteries were evaluated with ultrasound. Results Body mass index (BMI), hemoglobin, LH levels and LH/FSH ratio were significantly higher in women with EMO than in those with FO. Increased androgens values were found in the EMO group, but only A and FT were significantly different (p=0.04). Ovarian volume and uterine artery PI were the only ultrasound features significantly different, with higher values in the EMO population (p<0.05). Considering these variables, with a receiving characteristic operating curve, new cut-offs were calculated, and a diagnostic assessment tool elaborated (area under curve [AUC] 0.88, specificity 99%, sensibility 59%, p<0.001]. Conclusions This diagnostic tool, specific for adolescents, could be useful in the management of oligomenorrhea. Recognizing and distinguishing EMO and FO is very important in order to establish an appropriate treatment and a correct follow-up.

Tools for Enhancement and Quality Improvement of Peer Assessment and Clinical Care in Endocrinology and Metabolism.

Members of the College of Physicians and Surgeons of Ontario Endocrinology and Metabolism Peer Review Network have been involved in a quality improvement project to help standardize the peer assessment of physicians practicing in endocrinology and metabolism. This has included developing state-of-the-art summaries of common endocrine problems by Canadian experts in endocrinology and metabolism. These tools have been developed in response to the educational needs, as identified by peer reviewers, of practicing endocrinologists in Ontario. These pedagogical tools aim not only to standardize the documentation of the clinical performance of endocrinologists but also to make the process more transparent and to improve the quality of patient care in Ontario. This article summarizes the project and also provides the tools developed for the endocrinology and metabolism section of the College of Physicians and Surgeons of Ontario.

Financial implications of telemedicine visits in an academic endocrine surgery program.

BACKGROUND: Telemedicine is an emerging medium for the delivery of ambulatory care, but the reimbursement profile of telemedicine visits in the surgical setting has not been well studied. METHODS: A retrospective assessment of telemedicine encounters for thyroid and parathyroid conditions occurring from April 2015 to April 2017 was performed. Financial reimbursement from commercial payers for new and established patient visits were compared between telemedicine visits and in-person visits. Patient "savings" in terms of travel distance and drive time were calculated. RESULTS: A total of 290 telemedicine encounters were conducted; 7% were initial consultations, 47% were postoperative visits, and 45% were follow-up visits. The median patient age was 57 years. The median round-trip travel distance saved was 123.6 miles with estimated drive time of 2.4 hours per encounter. In 2% of cases, a second in-person visit within the 90-day global period occurred after a postoperative telemedicine encounter. Charges were filed for 67 encounters. The initial unpaid claims rate was 6%, which was consistent with the unpaid claims rate for in-person visits. The charge-to-collection ratio was comparable to that of in-person visits. There was a higher ratio of level 2 visits in the telemedicine encounters. Over the study period, 70 clinic hours were liberated via the use of telemedicine. CONCLUSION: Endocrine surgery telemedicine visits have the same level for level reimbursement profile as in-person visits. Down-coding and elimination of components of in-office physical examinations may lead to modest decreases in overall reimbursement. Other advantages include reallocation of clinic resources and decreased travel burden for patients.

Monitoring of Metabolic, Cardiac, and Endocrine Indicators in Youth Treated With Antipsychotics as Reported by Health Care Professionals.

BACKGROUND: It is unclear how youth treated with antipsychotics are monitored. The purpose of this study was to assess monitoring of metabolic, cardiac, and endocrine indicators in youth (<18 years old) treated with antipsychotics as reported by health care professionals in the Netherlands. METHODS: A questionnaire was designed to collect information from health care professionals regarding the monitoring of youth treated with antipsychotics. Data were collected at a national conference. FINDINGS AND RESULTS: Fifty-nine health care professionals completed the questionnaire, of which 53 (89.8%) were child and adolescent psychiatrists (approximately 20% of all child and adolescent psychiatrists in the Netherlands). More than 80% of respondents reported monitoring physical indicators-weight, height, body mass index, heart rate, and blood pressure-and over 50% reported monitoring laboratory indicators-lipid profile, blood glucose, and prolactin level. Most of the respondents reported monitoring physical indicators more than twice per year and laboratory indicators once per year. Almost all respondents (56/59, 94.9%) reported monitoring according to a clinical guideline or protocol. Only 1 respondent reported monitoring the indicators completely according to the clinical guideline. Respondents mentioned that facilitating factors for monitoring, such as access to electrocardiogram facilities, were insufficiently available. CONCLUSIONS: Although all health care professionals reported monitoring metabolic, cardiac, and endocrine indicators in youth treated with antipsychotics, great variability exists in reported monitoring practices. Factors contributing to this variability must be assessed to optimize the benefit-risk ratio for the individual patient.

Referring Quality Assessment of Primary Health Care for Endocrinology in Rio Grande do Sul, Brazil.

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.

[High-tech medical care in surgical endocrinology].

The number of patients with endocrine system diseases increases annually. Widespread introduction of screening programs and improvement of laboratory and instrumental diagnostic is one of the most important causes for this. Treatment of patients with endocrine system diseases within the high-tech medical care leads to perform the unique surgical interventions. It increases survival and patients' life quality.

Preclinic investigations accelerate decision-making, reduce delays in treatment and are highly popular with endocrinology patients and staff.

OBJECTIVE: Endocrine diagnosis relies on a thorough history, examination and confirmatory biochemical tests. Previously, in our unit, tests were performed after new patients attended clinic. We proposed that diagnosis and management would be improved if this system was inverted. DESIGN: Clinicians and chemical pathologists reviewed available guidance and local practice to determine the key tests to confirm or refute most common endocrine disorders. A system was developed for clinicians to categorize new referrals into diagnostic groups: for example, nodular thyroid disease or possible polycystic ovarian syndrome. Standard letters were developed and sent to patients explaining the requirement for tests to be performed prior to first hospital appointment. The letters and requests for investigation sets were standardized for each diagnostic group and generated via a one-click automated method. After one year, clinical outcomes were audited and patients and staff surveyed. RESULTS: The time from referral to confirming diagnosis and starting treatment was halved: mean 11·8-5·7 weeks (P < 0·001). Acute patients were also discharged from clinic earlier: mean 17 to 10·3 weeks (P < 0·005). Ninety four percent patients surveyed had their tests performed easily prior to attending their appointment. Hundred per cent of patients, 100% of hospital staff and 93% referring general practitioners who responded felt the system improved patient care and should continue. CONCLUSIONS: Performing investigations prior to new patient appointments is practical, popular with staff and patients and has dramatically improved our referral to treatment statistics by reducing delays prior to diagnosis. This system could be used as a model for other departments.

[Gender-specific differences in age-associated endocrinology]. / Geschlechtsspezifische Unterschiede der Endokrinologie im Alter.

The endocrine system is intimately involved in modulating lifespan and quality of life. Facing an ever increasing proportion of aged people in the western society, there is great interest in understanding the complex interrelations between increasing age and hormonal regulation. Age-associated endocrinological changes comprise the decline of basal hormonal levels, pulsatile hormone distribution, and activity of hormonal axis, which result in changes in body composition. Men and women experience different age-associated alterations of the hormonal system. Aging per se is a risk factor for diseases like diabetes mellitus type 2, thyroid disorders, osteoporosis, frailty, and sarcopenia. Gender-specific differences with respect to symptoms, interactions, diagnosis, and therapy must be taken into consideration. Current data do not allow a general recommendation for hormonal substitution, neither for women nor for men. New research approaches following a multifactorial pathway are required to elucidate the complexity of age-associated endocrinological changes and to develop gender-specific therapies for endocrinological diseases.

Promoting excellence in the care of pediatric endocrine diseases in the developing world.

On behalf of the Global Pediatric Endocrinology and Diabetes group, the authors provide a perspective on the rights of a child as enshrined in the United Nations Convention on the Rights of the Child (1989) concerning the care of pediatric endocrine disorders and diabetes mellitus, throughout the world, with particular reference to care in resource-constrained settings. In this article, we define the spectrum of health care needs of the child with an endocrine disorder and how they may be addressed, in terms of education, research, and development of sustainable programs for improved health outcomes. We emphasize the responsibilities of medical communities, the pharmaceutical industry, and relevant governments in promoting and supporting such concepts.

A comparative quality assessment of evidence-based clinical guidelines in endocrinology.

CONTEXT: Evidence-based clinical guidelines in endocrinology attempt to improve and standardize patient care. There has been an expansion in guideline production although some of the heterogeneous methods used to assess the quality of the underlying evidence base might limit interpretation and implementation. DESIGN: Current and archived guidelines from major endocrine organizations were accessed. The organizations used six different methods to rate underlying evidence, including Grading of Recommendations Assessment, Development and Evaluation (GRADE). To allow direct comparison between guidelines produced by different organizations, the levels of evidence used to generate them were graded according to the standardized system: 'high' based on randomized, controlled trials and meta-analyses, 'moderate' based on nonrandomized studies and 'low' based on expert opinion. RESULTS: There was an increase in guideline production over time (1995-2000 = 9, 2001-2005 = 12, 2006-2011 = 36). Three guidelines were updated with an average delay of 4·3 years and an increase in recommendations per guideline (21·1%). Encouragingly, whilst updates had similar levels of 'high'-quality evidence, there was increased reliance on 'moderate'-category evidence and less on 'low''-quality evidence' ('high', 6·3% vs 6·5%; 'moderate', 46·1% vs 59·1%; 'low', 47·7% vs 34·4%). A high proportion of 'low'-category evidence was seen throughout all organizations. Rarer conditions and recommendations concerning treatment efficacy were particularly reliant on 'low'-category evidence. CONCLUSIONS: The level of evidence underpinning current guidelines highlights areas in need of well-designed, collaborative clinical research. Furthermore, criteria to define when guideline updates are necessary are currently lacking. A standardized method of assessment, such as GRADE, would promote understanding and compliance by guideline users with the ultimate aim of enhancing patient care.

Molecular genetic testing in endocrinology - a practical guide.

OBJECTIVE: To discuss the factors to consider when evaluating patients with a suspected genetic endocrine disorder, so as to guide practicing endocrinologists through the process of genetic testing and result interpretation. METHODS: The author's experience and review of appropriate literature have been used to give a personal perspective on the role of genetic testing in hereditary endocrine disorders. RESULTS: Recent advances in our understanding of genetics and genomics have uncovered that they have a far more important role in the pathogenesis of endocrine disease than previously appreciated. Not only are we expanding our understanding of rare mendelian disorders such as multiple endocrine neoplasia type 1 and 2, but we are also beginning to understand the clinical significance of genetic factors in the pathogenesis of common disorders such as obesity and dyslipidemia. CONCLUSIONS: It can be difficult to appreciate the clinical significance and utility of genetic testing that is currently available, and the interpretation of genetic test results can be challenging. Decisions on whether genetic testing is needed should be made on a case-by-case basis, with the endocrinologist and geneticist working together from the outset.

[Services portfolio of a department of endocrinology and clinical nutrition]. / Cartera de Servicios de Endocrinología y Nutrición.

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.

Bone age assessment in the workup of children with endocrine disorders.

Bone age is a measure of developmental age, or physiological maturity, which represents more truthfully than chronological age, how far an individual has progressed towards full maturity. It is particularly helpful in the clinical workup of children with growth and/or puberty disorders as well as in treating decisions, such as whether to start replacement therapy in a patient with hypogonadism. Skeletal maturity assessment plays a pivotal role in confirming the diagnosis of normal variants of growth such as familial short stature and constitutional delay of growth, in interpreting hormone tests during puberty, and in the diagnosis of precocious puberty and hyperandrogenism. On the other hand, it is important to recognize that overemphasizing bone age evaluation can be misleading if not used in the proper settings. Adult height prediction is based on skeletal maturity assessment and can be used to predict with acceptable accuracy which adult height will be achieved by a 'normal' child. However, the predictions do not apply to children with endocrine or bone pathologies affecting growth.

Assessment of endocrine abnormalities in severe traumatic brain injury: a prospective study.

OBJECTIVE: The frequency and pattern of endocrine abnormalities among patients with traumatic brain injury have been the subject matter of very few studies. This study was intended to assess the pattern of endocrine dysfunction following severe head injury. METHODS: Severe head injury patients admitted to the Department of Neurosurgery, All India Institute of Medical Sciences, New Delhi, from January to December in 1 year formed the study group. Apart from clinical assessment, NCCT of the head was performed on all patients on admission. A complete anterior pituitary hormone analysis was performed within 24 h of injury and was repeated at 2 weeks, 3 months and 6 months amongst patients who survived. RESULTS: A total of 99 patients were included in the study. Forty of our patients succumbed in the hospital. Rest of the patients were followed up for 6 months. Elevations of cortisol followed by prolactin were the most common hormonal derangements at admission. Midline shift on CT scans was inversely related to cortisol elevation and directly related to GH elevation. Infarct on CT scans was inversely related to cortisol and LH elevation. A significant alteration was found in the decreasing trend of the mean T4 values and normalisation or a decreasing trend from initially elevated mean cortisol and GH levels during follow-up (p < 0.05). CONCLUSIONS: This study reveals that abnormalities in hormonal profiles appear to be relatively common in severe traumatic brain injury and fluctuate significantly over at least 6 months; there is a correlation with age and radiological findings. Performance of hormonal analysis evaluation should be considered in patients with severe brain injury so that appropriate hormonal replacement can be done to optimise the clinical outcome.
