Abstract
Acromegaly is a rare disease and thus challenging to accurately quantify epidemiologically. In this comprehensive literature review, we compare different approaches to studying acromegaly from an epidemiological perspective and describe the temporal evolution of the disease pertaining to epidemiological variables, clinical presentation and mortality. We present updated epidemiological data from the population-based Danish cohort of patients with acromegaly (AcroDEN), along with meta-analyses of existing estimates from around the world.Based on this, we conclude that the incidence, prevalence and age at acromegaly diagnosis are all steadily increasing, but with considerable variation between studies. An increased number of incidental cases may contribute to the increase in incidence and age at diagnosis, respectively. The clinical features at presentation are trending toward a milder disease phenotype at diagnosis, and advances in therapeutic options have reduced the mortality of patients with acromegaly to a level similar to that of the general population. Moreover, the underlying cause of death has shifted from cardiovascular to malignant neoplastic diseases.

Abstract
OBJECTIVE To study time-related changes in the prevalence and patient characteristics of acromegaly, as well as to assess the impact of changes in treatment on disease control. METHODS A total of 107 patients with acromegaly were identified by healthcare registries and subsequently validated by patient chart review over a three-decade period (1992-2021). A systematic literature review focusing on the incidence and prevalence of acromegaly was performed identifying 31 studies. RESULTS The prevalence of acromegaly significantly increased throughout the study period (R2 = 0.94, p < .001) and was 122 cases/106 persons in 2021 whereas the annual incidence remained constant at 4.6 cases/106 persons. The age at the first sign of acromegaly and the age at diagnosis significantly increased during the study period, whereas growth hormone and insulin-like growth factor I decreased. Incidentalomas constituted 32% of all cases diagnosed with acromegaly in the last decade. Primary surgery was used in 93% of all cases, and repeated surgery decreased from 24% to 10% during the three decades. The use of first-generation somatostatin analogues (21%-48%) and second-line medical treatment (4%-20%) increased with a concomitant improvement of biochemical disease control (58%-91%). CONCLUSION The prevalence of acromegaly is higher than previously reported and the clinical presentation has shifted towards a milder phenotype. Modern treatment of acromegaly enables individualized treatment and disease control in the majority of patients.

Abstract
Ecuador has shown a growth in its scientific production since 2011, representing 85% of the total historical production. These investigations are reflected in scientific publications, which address world interest topics and serve as a link for the university, business, and society. This work aims to analyze the scientific production generated by Ecuador in the period of 1920–2020 using bibliometric methods to evaluate its intellectual structure and performance. The methodology applied in this study includes: (i) terms definition and search criteria; (ii) database selection, initial search, and document compilation; (iii) data extraction and software selection; and finally, (iv) analysis of results. The results show that scientific production has been consolidated in 30,205 documents, developed in 27 subject areas, in 13 languages under the contribution of 84 countries. This intellectual structure is in harmony with the global context when presenting research topics related to “Biology and regional climate change”, “Higher education and its various approaches”, “Technology and Computer Science”, “Medicine”, “Energy, food and water”, and ”Development and applications on the Web”. Topics framed in the Sustainable Development Goals (SDGs), sustainability, climate change, and others. This study contributes to the academic community, considering current re-search issues and global concerns, the collaboration between universities and countries that allow establishing future collaboration links.

Abstract
AIMS Describe the local characteristics, methodology and results of the registry of acromegalic patients in Colombia (RAPACO). METHODS Multicenter, retrospective study based on the registry of acromegalic patients in Colombia: RAPACO. The data collected included: demographics, diagnosis, approximate time of disease evolution, data on weight, height, body mass index (BMI), neck circumference (NC) abdominal circumference (AC) hip circumference (HC) and waist/hip ratio (WHR); clinical and biochemical data at the time of diagnosis, etiology, immunohistochemistry of the tumor and information related to types of treatment. Descriptive analytics were employed. RESULTS A total of 201 patients (60% females) with an average age at registration of 49.5 ± 14.6 years and an average time of evolution of the disease of 6.96 ± 4.5 years. Average weight was 75.1 Kg ± 12.98, with an average BMI of 28.11 ± 4.33. The most frequent symptoms mentioned at the time of diagnosis were extremity enlargement and headache. The most frequent comorbidity was arterial hypertension in 50.3% of the cases. 78.6% of cases were caused by macroadenoma. 80.1% received surgical treatment, 77.6% were under medical treatment, of which 95.7% were receiving somatostatin analogues. 26.4% of patients were treated with radiation therapy. Of the patients who received any type of clinical treatment, only 2.5% reported biochemical control at registration. CONCLUSION It is important to recognize the local epidemiological, clinical, biochemical and treatment characteristics in order to assist in further understanding this pathology to implement local measures to improve both the quality of life as well as the prognosis of the patients diagnosed.

Abstract
The aim of this article is to present a historical review on giants and dwarves living in South America and the contribution of South America's researchers to scientific advances on growth hormone (GH) and human disorders related to GH excess and GH deficiency (GHD). We went back in time to investigate facts and myths stemming from countless reports of giants who lived in the Patagonia region, focusing on what is currently known about gigantism in South America. Additionally, we have reviewed the exceptional work carried out in two of the world's largest cohorts of dwarfism related to GH-IGF axis: one living in Itabaianinha, Brazil, suffering from severe GHD due to a mutation in the GHRH receptor (GHRHR) gene, and the other living in El Oro and Loja provinces of Ecuador, who are carriers of GH receptor gene mutation that causes total GH insensitivity (Laron syndrome). Importantly, we present an overview of the outstanding medical contribution of Jose Dantas de Souza Leite, a Brazilian physician that described the first cases of acromegaly, and Bernardo Alberto Houssay, an Argentine researcher graced with the Nobel Prize, who was one the first scientists to establish a link between GH and glucose metabolism.

Hormones (Athens) 2018; 17:373-381.

Abstract
BACKGROUND Worldwide variations exist in the diagnosis and management of patients with acromegaly. For such a rare condition, the knowledge and perception of physicians would most likely direct the care of patients. However, the adherence of physicians in non-Western regions to guidelines for the diagnosis and management of acromegaly has not been previously ascertained. METHODS An online survey was conducted to assess the perceptions and practice of physicians regarding acromegaly diagnosis and management as per international guidelines. An electronic questionnaire containing key questions was mailed, initially to physicians in Saudi Arabia (KSA) and later to other countries in the Middle East and North Africa (MENA) region. Additional questions were included to ensure the relevance of the respondents' replies. The responses were captured and summarized anonymously. Descriptive comparisons were made with two similar international and national surveys from other regions. RESULTS Two hundred forty-seven doctors responded to the survey. Of these, 155 (64.5%) fulfilled the inclusion criteria and, in particular, confirmed having treated acromegaly patients in the previous 12 months, and they constituted the basis of this study. The three most common referring specialties for patients were internists (44; 28.4%), neurosurgeons (46; 29.6%), and family medicine physicians (42; 27.1%), respectively. The combination of growth hormone (GH) nadir during the oral glucose tolerance test (OGTT) and elevated insulin-like growth factor-1 (IGF-1) levels was used by 99 physicians (63.9%) to diagnose acromegaly. The main determinant for treatment choice was tumor mass characteristics confirmed by 117 respondents (75.5%) with neurosurgery as first treatment choice confirmed by 124 respondents (80%). Combined measurement of IGF-1 and GH levels after OGTT at 3 months after surgery was the most widely used criterion for assessment of surgical outcomes, confirmed by 82 physicians (52.9%). The biggest barriers to optimal management of acromegaly as perceived by 38.1% and 35.5% of the respondents were high cost of medications and lack of physicians' awareness, respectively. CONCLUSIONS The majority of the surveyed physicians reported variable adherence to the international acromegaly guidelines. Clearly, higher awareness is needed among physicians for early diagnosis and timely referral for specialist management.

Abstract
BACKGROUND Acromegaly results from the hypersecretion of growth hormone. Because of the low incidence rates of this disease worldwide, few clinical trials evaluating drug treatments have been conducted. OBJECTIVES To conduct the first network meta-analysis simultaneously comparing all available drugs used in acromegaly treatment so as to provide more robust evidence in this field. METHODS A systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Cochrane Collaboration recommendations (PROSPERO database under the registration number CRD42017059880). The electronic searches were conducted in PubMed (MEDLINE), Scopus, and Web of Science databases. Randomized controlled trials comparing any drug for the treatment of acromegaly head-to-head or versus placebo were included. Outcomes concerning the efficacy and safety of treatments were evaluated. The statistical analyses were performed using Aggregate Data Drug Information System version 1.16.8 (drugis.org, Groningen, The Netherlands). RESULTS The initial search retrieved 2059 articles. Of these, 10 randomized controlled trials were included in a qualitative analysis and 7 in a quantitative analysis. The network meta-analysis for the efficacy outcome (number of patients achieving insulinlike growth factor 1 control) showed that pegvisomant and lanreotide autogel were statistically superior to placebo (odds ratio [95% credible interval] 0.06 [0.00-0.55] and 0.09 [0.01-0.88]). No further differences were found. The probability rank indicated that pegvisomant and pasireotide have the highest probabilities (33% and 34%, respectively) of being the best therapeutic options. No major side effects were noted. CONCLUSIONS Pegvisomant is still a good option for acromegaly treatment, but pasireotide seems to be a promising alternative. Nevertheless, other important key factors such as drug costs and effectiveness (real-world results) should be taken into account when selecting acromegaly treatment.
