Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):58-
Introduction:
Obesity is a chronic disease characterized by complex
alterations in body composition and metabolic health. Traditional reliance on body weight may overlook important
physiological adaptations during lifestyle intervention.
Methodology:
A cohort of 99 participants at programme entry underwent
body composition assessment using bioelectrical impedance analysis. Parameters included percent body fat (PBF),
visceral fat area (VFA), skeletal muscle index (SMI), and
phase angle (PhA). Correlation analyses were performed to
explore relationships between adiposity, muscle mass, and
cellular health.
Results:
Participants demonstrated elevated adiposity (PBF 38.9 ±
8.9%; VFA 142.9 ± 56.1 cm²). PhA was inversely associated
with VFA (r ≈ −0.23, p <0.05) and positively associated with
SMI (r ≈ 0.49, p <0.001). Notably, a subset of overweight
individuals exhibited relatively preserved PhA, indicating
heterogeneity in metabolic health despite similar adiposity
levels.
Conclusion
Body composition and PhA provide complementary
insights into metabolic health beyond body weight. These
findings support the role of bioimpedance-derived parameters in identifying metabolic heterogeneity and guiding
personalized obesity management.

2.Research advance on the clinical phenotypes and molecular genetic mechanisms of Microcephalic primordial dwarfism.
Chinese Journal of Medical Genetics 2026;43(1):76-80
Primordial dwarfism (PD) refers to a group of monogenic genetic disorders characterized by intrauterine growth restriction (IUGR) and severe, persistent postnatal growth retardation. These diseases have been associated with variants of multiple genes whose products are mainly involved in critical cellular biological processes such as maintenance of genomic stability, DNA damage repair, mRNA splicing regulation, and centrosome function. Variants of such genes can directly impair cell proliferation and developmental potential. With the widespread application of molecular genetic technologies such as high-throughput sequencing, significant progress has been made in the research of PD. This article focuses on the major subtypes of PD, including Seckel syndrome, Microcephalic osteodysplastic primordial dwarfism (MOPD) types I/III, MOPD type II, and Meier-Gorlin syndrome. It has systematically summarized the advances in their clinical phenotypic characteristics, pathogenic genes, and molecular mechanisms, with an aim to deepen the understanding of the essence of growth disorders associated with PD.

OBJECTIVE:
To analyze the phenotype and genotype of a neonate with Osteo-oto-hepato-enteric syndrome (O2HE) and review the literature.
METHODS:
A female neonate diagnosed with O2HE syndrome on December 13, 2024 at the First Affiliated Hospital of Zhengzhou University was selected as the study subject, and her clinical characteristics were analyzed, and pathogenic variants were explored by whole exome sequencing (WES). This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: 2025-KY-1038).
RESULTS:
The proband, a female infant, was delivered by Cesarean section at 36+1 weeks of gestation. Five days after birth, she had developed severe diarrhea, mild cholestasis, sensorineural hearing loss, and growth retardation. WES revealed that she has harbored novel compound heterozygous variants c.512delA (p.Lys171Serfs*64) and c.698C>A (p.Thr233Asn) of the UNC45A gene, which were inherited from her mother and father, respectively. A total of 8 English papers were retrieved, which involved 16 patients from 14 families. Combined with our case, the 17 patients included 13 (76.5%) females and 4 (23.5%) males. Four patients (23.5%) had consanguineous parents. One case was excluded from further genetic analysis due to co-morbidity with other genetic variants. The primary clinical features included diarrhea (87.5%), cholestasis (81.3%), sensorineural hearing loss (31.3%), bone fragility (37.5%), and developmental delay (50.0%). Bi-allelic compound heterozygous mutations were identified in 12 patients (75.0%), and homozygous variants in 4 (25.0%). These included missense, nonsense, frameshift and deletional variants. The c.710T>C (p.Leu237Pro) variant was identified for 5 times, 3 of which were in homozygote forms.
CONCLUSION
O2HE syndrome should be suspected in cases with diarrhea, cholestasis, and hearing abnormalities during early postnatal period. Genetic testing facilitate early identification, genetic diagnosis and treatment.

BACKGROUND
Stunting remains a major public health issue in Indonesia, particularly in regions like Pandeglang Regency, where prevalence rates are high. Understanding the contributing factors is essential for targeted interventions.
OBJECTIVEThis study aimed to analyze factors associated with stunting among toddlers using a mixed-methods approach.
METHODSA cross-sectional mixed-methods study was conducted in two health centers in Banten Province from December 2021 to January 2022. Quantitative data were collected using a structured questionnaire and analyzed using chi-square tests (pRESULTS
There is a relationship between maternal knowledge, history of exclusive breastfeeding, history of supplementary feeding, support from health workers, and socio-economic status with the prevalence of stunting. However, the pattern of exclusive breastfeeding and seeking health services in the working areas of Bangkonol Health Center and Kaduhejo Health Center, Pandeglang Regency, is not good enough and needs to be improved. Health workers need to educate mothers with toddlers about patterns of providing complementary feeding, food preparation, and storage, and basic health practices to prevent stunting.

Abstract
Pituitary adenomas are common intracranial tumors that can be classified based on their hormonal activity and size. While microadenomas are more frequent, macroadenomas often present with significant clinical manifestations due to hormone excess or mass effects. In older populations, diagnosis is often delayed as physical changes may be subtly attributed to normal aging. A 61-year-old woman presented with progressively coarsening facial features and enlargement of the hands and feet. Physical examination confirmed acral enlargement, and the patient reported persistent headaches and a history of hypertension. Laboratory investigations revealed significantly elevated levels of growth hormone (GH) at 18.9 ng/mL and insulin-like growth factor-1 (IGF-1) at 865.6 ng/mL. Other pituitary functions, including prolactin and morning cortisol, were within normal limits. Magnetic resonance imaging (MRI) identified a 1.3 × 2.5 × 1.0 cm pituitary macroadenoma. The patient subsequently underwent successful endonasal endoscopic transsphenoidal surgery for tumor resection. This case underscores the necessity of maintaining a high index of suspicion for acromegaly in elderly patients presenting with unexplained acral and facial changes. Comprehensive endocrine evaluation and advanced imaging are critical for achieving an accurate diagnosis and ensuring timely surgical intervention to prevent disease progression.

6.When Hypoglycemia Speaks Louder Than the Chest: A Decade-Late Recurrence of IGF-2-Mediated Non-Islet Cell Tumor Hypoglycemia
Li Li Kwan ; Deviga Lachumanan
Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):67-68
Introduction:
Non-islet cell tumor hypoglycemia (NICTH) is a rare
paraneoplastic syndrome caused by tumor secretion of
insulin-like growth factor-2 (IGF-2), leading to recurrent
hypoinsulinemic hypoglycemia. It is most commonly
associated with large mesenchymal tumors, such as solitary fibrous tumor, particularly those arising from the pleura
or lungs. This phenomenon, also known as Doege–Potter
syndrome, may precede tumor detection or signal tumor
recurrence. We report a striking case of late malignant
recurrence presenting solely with hypoglycemia after
a decade of remission.
Case:
A 68-year-old female was initially presented in 2016
with respiratory symptoms and recurrent symptomatic
fasting and post-prandial hypoglycemia, and was found
to have a large left upper lobe mass. Tumor resection in
2017 resulted in complete resolution of hypoglycemia.
She remained asymptomatic for several years. In
2023, she developed recurrent hypoglycemia without
respiratory or constitutional symptoms. Biochemical
evaluation demonstrated hypoinsulinemic hypoglycemia
with suppressed insulin and C-peptide, low IGF-1, and
markedly elevated IGF-2, resulting in an IGF-2:IGF-1 ratio
of 25, consistent with IGF-2-mediated NICTH. Computed
tomography imaging revealed a large left thoracic mass
with invasion into the intercostal muscles and diaphragm
with extension toward the stomach, associated with
contralateral lung nodules and possible liver metastases,
suggesting recurrent malignant disease. Hypoglycemia
improved with glucocorticoid therapy, and the patient
was referred for oncological assessment. Despite initiation
of systemic chemotherapy, her disease progressed and she
succumbed during treatment.
Conclusion
This case highlights several important lessons: Firstly,
recurrent hypoinsulinemic hypoglycemia warrants
evaluation for NICTH even in the absence of tumor-related
symptoms. Secondly, solitary fibrous tumors may recur
or undergo malignant transformation after prolonged
disease-free intervals; and glucocorticoids provide effective
metabolic control but do not alter oncologic prognosis.
Long-term surveillance should be considered in patients
with prior solitary fibrous tumors due to the risk of delayed
recurrence and paraneoplastic complications.

OBJECTIVE
This study aimed to investigate the determinants linked to stunting among infants and young children aged 0-23 months in the Fourth District of Camarines Sur.
METHODSAn analytical cross-sectional study was conducted among 628 primary caregivers with infants and young children aged 0-23 months in four municipalities of the Fourth District of Camarines Sur, Philippines, using a two stage stratified random sampling design. Data on sociodemographic and economic factors were collected through face-to-face interviews. Infant and young child feeding (IYCF) indicators were assessed using a list-based approach, while weight and length were evaluated using the World Health Organization Anthro Plus software. Descriptive statistics and multiple logistic regression were done using R statistical software version 4.3.1.
RESULTSThe study revealed that the prevalence of stunting was of significant public health concern, reaching 42.8%. Holding other variables constant, age of the child (OR=0.77; 95% CI: 0.63-0.94), having college undergraduate mothers (OR=0.26; 95% CI: 0.05-1.28), and belonging to a poor income household (OR=0.40; 95% CI: 0.14-0.88) were associated with stunting among infants aged 0.01-6.00 months. Moreover, after controlling for the confounding effects of other variables, age (OR=1.09; 95% CI: 1.05-1.14) and sex of the child (OR=1.55; 95% CI: 1.05-2.28) were associated with stunting among older children aged 6.00-23.99 months.
CONCLUSIONThis study emphasizes the challenge of stunting in the Fourth District of Camarines Sur. None of the IYCF indicators were associated with stunting; however, maternal education, the child’s age, sex, and socioeconomic status were identified as significant factors influencing stunting. Addressing these determinants through targeted interventions focusing on improving maternal education and enhancing socio-economic conditions were crucial to reducing stunting in the study areas.

OBJECTIVE:
To investigate the potential mechanism by which electroacupuncture (EA) induces macrophage polarization to promote muscle satellite cell proliferation and differentiation, accelerating the repair of acute skeletal muscle injury.
METHODS:
Forty-two SPF-grade SD rats were randomly divided into three groups: a blank group (n=6), a model group (n=18), and an EA group (n=18). The model and EA groups established acute blunt contusion model of the right gastrocnemius muscle using a self-made striking device. From day 1 after modeling, rats in the EA group received EA at "Chengshan" (BL57) and "Yanglingquan" (GB34) on the right side, using disperse-dense wave with a frequency of 2 Hz/100 Hz and a current of approximately 2 mA. The EA treatment was administered once daily for 30 minutes for 3, 7, or 14 days based on the designated sampling time points. Gait analysis was performed using the Cat Walk XTTM system. Hematoxylin-eosin (HE) staining was used to observe the morphological changes in the gastrocnemius muscle. Masson staining was applied to evaluate collagen fiber content. Immunofluorescence was used to detect the expression of proliferating cell nuclear antigen (PCNA) in muscle satellite cells. Immunohistochemistry was used to assess the expression levels of CD68 and CD206, markers of macrophages. Serum levels of pro-inflammatory cytokines (TNF-α, IL-1β) and anti-inflammatory cytokines (IL-10, IL-13) were detected using ELISA.
RESULTS:
Compared with the blank group, the model group showed a significant reduction in average movement speed on days 3 and 7 after modeling (P<0.05), and a decrease in the right hind limb stride length on day 3 (P<0.05). Compared with the model group, the EA group showed increased average movement speed and right hind limb stride length on day 7 (P<0.05). In the blank group, the gastrocnemius muscle on the right side showed uniform and consistent inter-fiber spacing, with neatly and regularly arranged muscle cells. In contrast, the model group exhibited enlarged inter-fiber spacing, edema, and significant infiltration of red blood cells and inflammatory cells, with progressively increasing fibrosis over time. By day 14 after modeling, the EA group showed a return to baseline levels of inflammatory cell infiltration, and the degree of fibrosis was significantly lower than that observed in the model group. Compared with the blank group, the ratio of collagen fibers in the gastrocnemius muscle of the model group increased significantly on days 3, 7, and 14 after modeling (P<0.05). Compared with the model group, the EA group exhibited a lower collagen fiber ratio on days 3, 7, and 14 (P<0.05). Compared with the blank group, PCNA positive expression in the gastrocnemius muscle of the model group was significantly increased on days 3, 7, and 14 after modeling (P<0.05). Compared with the model group, the EA group exhibited significantly higher PCNA positive expression on days 3 and 7 (P<0.05). Compared with the blank group, the model group showed a significant increase in CD68-positive macrophage expression in the gastrocnemius muscle on day 3 after modeling (P<0.05), while CD206-positive macrophage expression increased on days 3, 7, and 14 (P<0.05). Compared with the model group, CD68 expression was significantly lower in the EA group on day 3 (P<0.05), whereas CD206 expression was significantly higher on days 3 and 7 (P<0.05), peaking on day 7 with CD206 expression. Compared with the blank group, serum TNF-α levels were significantly elevated in the model group on days 3 and 7 after modeling (P<0.05), while serum IL-1β levels were increased on days 3, 7, and 14 (P<0.05). Serum IL-10 and IL-13 levels were significantly higher on day 7 after modeling (P<0.05). Compared with the model group, the EA group exhibited lower serum TNF-α level on day 3 (P<0.05) and reduced serum IL-1β levels on days 3 and 7 (P<0.05), while serum IL-10 and IL-13 levels were significantly increased on day 7 (P<0.05).
CONCLUSION
EA could promote the repair of acute blunt contusion-induced gastrocnemius muscle injury by regulating the proliferation and differentiation of muscle satellite cells. This process is closely related to macrophage polarization.

OBJECTIVE:
To explore the characteristics and rules of the locations of acupoints selected in weight loss after syndrome differentiation of acupuncture and moxibustion, and provide quantitative evidence for the location specificity of acupoint selection in weight loss.
METHODS:
Clinical research articles on acupoint selection based on syndrome differentiation of acupuncture and moxibustion in weight loss were retrieved in China National Knowledge Infrastructure (CNKI), from the inception to September 20th, 2024, and the data about acupoints and differentiated syndromes were extracted. Based on graph theory, the acupoint-syndrome network was established and its topological parameters such as node degree, value of betweenness centrality, description length and number of community were calculated.
RESULTS:
①The description length of the limbs was 4 255.592, and that of the trunk was 3 274.312. The information contained in the acupoint-syndrome network for the acupoints on the limbs was greater than that for those on the trunk. ②The value of betweenness centrality and node degree showed a nonlinear relationship, with R²of 0.812 1 for the trunk and 0.321 8 for the limbs. The values of betweenness centrality for the acupoints on the trunk were uniformly distributed, and the difference among these values was much smaller than that for the acupoints on the limbs. It suggested that the distance from each trunk acupoint to network center was similar, and the importance among these acupoints to network was similar, while the importance among acupoints located on the limbs was different significantly. ③The frequency proportion of acupoints on the trunk showed uniform distribution among different syndromes, while that of some acupoints located on the limbs such as Taichong (LR3), Neiting (ST44) and Taixi (KI3) presented a correlation with the syndromes.
CONCLUSION
In weight loss with acupuncture and moxibustion, the correlation between the limb acupoints and syndromes is more diverse and specific than that between the trunk acupoints and syndromes. The differences in acupoint selection for simple obesity treated with acupuncture and moxibustion are mostly reflected in the acupoints on the four limbs rather than those on the trunk. It provides an approach to acupoint selection for "local weight loss" and "general regulation" in treatment with acupuncture and moxibustion.

Chinese Acupuncture & Moxibustion 2025;45(12):1759-1769
OBJECTIVE:
To explore the effect and mechanism of acupuncture at "Weizhong" (BL40) on microcirculation of paravertebral skeletal muscle in rats with chronic blunt injury of lumbar muscle based on the insulin-like growth factor-1 (IGF-1)/phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) pathway.
METHODS:
Forty-eight SPF-grade SD rats were randomized into a blank group (8 rats) and a modeling group (40 rats). Chronic blunt injury model was established by weight impact method in the modeling group. Forty rats were successfully modeled, and were randomly divided into a model group, an acupuncture at Weizhong group (Weizhong group), an acupuncture at non-acupoint group (non-acupoint group), an inhibitor group, and an inhibitor+acupuncture at Weizhong group (inhibitor+Weizhong group), 8 rats in each group. In the Weizhong group and the inhibitor+Weizhong group, acupuncture was applied at bilateral "Weizhong" (BL40). In the non-acupoint group, acupuncture was applied at non-acupoints, i.e. points 0.5 cm inward from bilateral "Weizhong" (BL40). The acupuncture intervention was delivered 20 min each time, once a day for continuous 2 weeks. In the inhibitor group and the inhibitor+Weizhong group, intraperitoneal injection of IGF-1 receptor (IGF-1R) inhibitor was given once a day, at a dosage of 2 mg/100 g, for continuous 2 weeks. Before modeling and on the 1st, 7th and 14th days of intervention, the body mass was measured. Before and after modeling, and after intervention, the limb grip strength and paw withdrawal threshold (PWT) were measured. After intervention, the morphology of psoas muscle was observed by HE staining; the ultrastructure of psoas muscle capillaries was observed by electron microscopy; the levels of serum vascular endothelial growth factor (VEGF) and endothelial nitric oxide synthase (eNOS) were detected by ELISA; and the protein and mRNA expression of IGF-1, IGF-1R, PI3K, AKT of psoas muscle was detected by Western blot and real-time PCR.
RESULTS:
Compared with the blank group, in the model group, the body mass on the 7th and 14th days of intervention, the limb grip strength, and the PWT of left and right hind feet were decreased (P<0.001, P<0.01); the skeletal muscle cells showed enlarged intercellular space, loosely arranged and irregularly shaped, the capillaries in the psoas muscle tissues were edematous, and the lumen of the blood vessels was obviously atrophied; the levels of serum VEGF and eNOS were decreased (P<0.001); in psoas muscle, the protein expression of IGF-1 and IGF-1R, as well as the p-PI3K/PI3K, p-AKT/AKT values were decreased (P<0.001), the mRNA expression of IGF-1, IGF-1R, PI3K and AKT was decreased (P<0.001, P<0.05). Compared with the model group, in the Weizhong group, the body weight was increased on the 7th and 14th days of intervention (P<0.001), the limb grip strength and the PWT of the left and right hind feet were increased (P<0.001, P<0.01); the arrangement of the skeletal muscle cells was relatively tight and the intercellular space was reduced, the blood vessels tended to be regular and the structure of the basement membrane was continuous, while the lumens of blood vessels were collapsed locally; the levels of serum VEGF and eNOS were increased (P<0.001); in psoas muscle, the protein expression of IGF-1 and IGF-1R, as well as the p-PI3K/PI3K, p-AKT/AKT values were increased (P<0.001), the mRNA expression of IGF-1, IGF-1R, PI3K and AKT was increased (P<0.001, P<0.01). Compared with the model group, in the inhibitor group, the body mass was decreased on the 7th and 14th days of intervention (P<0.05, P<0.01); the limb grip strength and the PWT of the left hind foot were decreased (P<0.01, P<0.001); the intercellular space of skeletal muscle cells was larger, the nuclei of the cells and erythrocytes were scattered in the intercellular space, the damage of the capillaries in the muscular tissues was serious, the collagen fibers were sparsely distributed and disorganized; the levels of serum VEGF and eNOS were decreased (P<0.001, P<0.01); in psoas muscle, the protein expression of IGF-1 and IGF-1R, as well as the p-PI3K/PI3K and p-AKT/AKT values were decreased (P<0.01, P<0.05, P<0.001), the mRNA expression of IGF-1, IGF-1R, PI3K, and AKT was decreased (P<0.01, P<0.001, P<0.05). Compared with the Weizhong group, in the non-acupoint group and the inhibitor+Weizhong group, the body mass was decreased on the 7th and 14th days of intervention (P<0.001, P<0.01), the limb grip strength was decreased (P<0.001); the morphology of muscle cell was relatively poor, with generally irregular, there was mild collapse and atrophy in the vascular lumen, and mild edema in the endothelial cells; the levels of serum VEGF and eNOS were decreased (P<0.001); in psoas muscle, the protein expression of IGF-1 and IGF-1R, as well as the p-PI3K/PI3K and p-AKT/AKT values were decreased (P<0.01, P<0.001), the mRNA expression of IGF-1, IGF-1R, PI3K, and AKT was decreased (P<0.001, P<0.01, P<0.05).
