The goal of the 8th edition of the Clinical Practice Guidelines for Obesity is to help primary care physician provide safe, effective care to patients with obesity by offering evidence-based recommendations to improve the quality of treatment. The Committee for Clinical Practice Guidelines comprised individuals with multidisciplinary expertise in obesity management. A steering board of seven experts oversaw the entire project. Recommendations were developed as the answers to key questions formul

Congenital lipoid adrenal hyperplasia (CLAH) is the most severe form of congenital adrenal hyperplasia, caused by defects in the steroidogenic acute regulatory protein (STAR). The STAR p.Q258* mutation is the most common mutation in China, Japan and Korea, suggesting a founder effect. This study aimed to investigate the phenotypic and mutation spectrum of STAR defects and identify the founder effect of the p.Q258* mutation in Korean patients with CLAH. For 45 patients from 42 independent pedigre

BACKGROUND: Fatty acid oxidation disorders (FAODs) include more than 15 distinct disorders with variable clinical manifestations. After the introduction of newborn screening using tandem mass spectrometry, early identification of FAODs became feasible. This study describes the clinical, biochemical and molecular characteristics of FAODs patients detected by newborn screening (NBS) compared with those of 9 patients with symptomatic presentations. METHODS: Clinical and genetic features of FAODs pa

Neurofibromatosis type 1 (NF1), a prevalent genetic disease that is transmitted in an autosomal dominant manner, is characterized by multiple cutaneous café-au-lait spots and neurofibromas as well as various degrees of neurological, skeletal, and neoplastic manifestations. The clinical features of NF1 increase in frequency with age, while the clinical diagnosis can remain undetermined in some pediatric patients. Importantly, affected patients are at risk for developing tumors of the central and

The prevalence of obesity in children and adolescents has been gradually increasing in recent years and has become a major health problem. Childhood obesity can readily progress to adult obesity. It is associated with obesity-related comorbidities, such as type 2 diabetes mellitus, hypertension, obstructive sleep apnea, non-alcoholic fatty liver disease, and the risk factor for cardiovascular disease. It is important to make an accurate assessment of overweight and obesity in children and adoles

Abstract Background Neurofibromatosis type 1 (NF1) is a common human genetic disease with age-dependent phenotype progression. The overview of clinical and radiological findings evaluated by whole-body magnetic resonance imaging (WBMRI) in NF1 patients < 3 years old assessed with a genetic contribution to disease progression is presented herein. Methods This study included 70 clinically or genetically diagnosed NF1 patients who received WBMRI before 3 years old. Clinical, genetic, and radiolo

Background: and explored the underlying mechanisms. Methods: (paricalcitol, 10 nM) for 48 h. The dose- and time-dependent cytotoxicity of PM with or without paricalcitol was determined via cell counting kit-8 assay. Cellular oxidative stress was assessed using commercially available enzyme-linked immunosorbent assay kits. The protein expression of vitamin D receptor (VDR), cytochrome P450(CYP)27B1, CYP24A1, renin, angiotensin converting enzyme (ACE), angiotensin II type 1 receptor (AT1), nuclear

Purpose: This study was performed to investigate the etiology, clinical features, and outcomes of patients with gonadotropin-independent precocious puberty (GIPP). Methods: The study included 16 patients (14 female and 2 male patients) who manifested secondary sexual characteristics, elevated sex hormones, or adrenal androgens with prepubertal luteinizing hormone levels after gonadotropin releasing hormone stimulation diagnosed between May 1994 and December 2015. Patients with congenital adrenal

Background ARID2 belongs to the Switch/sucrose non-fermenting complex, in which the genetic defects have been found in patients with dysmorphism, short stature and intellectual disability (ID). As the phenotypes of patients with ARID2 mutations partially overlap with those of RASopathy, this study evaluated the biochemical association between ARID2 and RAS-MAPK pathway. Methods The phenotypes of 22 patients with either an ARID2 heterozygous mutation or haploinsufficiency were reviewed. Comprehen

OBJECTIVES: To evaluate the long-term effectiveness of weekly vs. daily growth hormone (GH) administration in children with GH deficiency. METHODS: This study, part of the "LG Growth Study", included a total of 996 children with GH deficiency (773 receiving daily GH and 193 receiving weekly GH). Anthropometric data were collected at baseline and every 12 months; clinical and laboratory data were collected at baseline and throughout the study. RESULTS: At baseline, the weekly GH group was older,

Constitutional mismatch repair deficiency (CMMRD) is a rare and highly aggressive cancer predisposition syndrome caused by biallelic germline mutations in mismatch repair genes. This condition is characterized by early-onset malignancies across multiple organ systems, including central nervous system tumors, hematological cancers, and gastrointestinal malignancies. CMMRD-associated tumors exhibit hypermutation and microsatellite instability, resulting in a high tumor mutation burden and renderin

Careful observation for gastrointestinal bleeding is warranted for patients on anticoagulation with extensive cutaneous angiokeratomas. Furthermore, our experience suggests that surveillance is needed to assess the prevalence and extent of gastrointestinal angiokeratomas in patients with FD.
