Hepatic alveolar echinococcosis is a highly invasive zoonotic parasitic disease with poor prognosis. Surgical intervention serves as the pivotal approach to achieve radical cure and improve the prognosis of hepatic alveolar echinococcosis patients. In recent years, with the popularization of the concept of precision surgery and the development of the multidisciplinary diagnosis and treatment model, the surgical treatment strategies for hepatic alveolar echinococcosis have been continuously enriched, and the selection of surgical procedures has become increasingly diversified. Although key surgical techniques such as radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation have achieved remarkable progress in clinical application, many insurmountable challenges still remain. Therefore, by sorting out the latest evidence-based advances in the field of surgical treatment for hepatic alveolar echinococcosis, this article focuses on discussing the application status and bottlenecks of radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation in hepatic alveolar echinococcosis, aiming to provide a reference for the clinical treatment of hepatic alveolar echinococcosis.

Abnormal synaptic plasticity is an early pathological feature of Alzheimer disease (AD). Synaptic damage and dysfunction initiate neuronal degeneration and death, ultimately leading to cognitive impairment. Traditional Chinese medicine (TCM) can effectively ameliorate cognitive dysfunction through multitarget regulation of synaptic plasticity. This review summarizes the mechanisms by which TCM, including active components, single herbs, and classical formulas, modulates synaptic plasticity, offering new insights for future research and clinical applications. Relevant experimental studies published between 2020 and 2024 were retrieved from major databases, including China National Knowledge Infrastructure, the National Science and Technology Library, Wanfang Data, Elsevier, ScienceDirect, PubMed, SpringerLink, and Web of Science. Network pharmacology and bioinformatics approaches were used to predict the therapeutic effects and mechanisms of TCM on AD-related synaptic plasticity. In total, 15 TCM single herbs and 11 TCM formulas were identified as enhancing AD-related synaptic plasticity. Additionally, 15 active ingredients targeting synaptic plasticity in AD were retrieved from TCM databases over the past decade. This review provides novel perspectives and strategic directions for future AD research and therapeutic development.

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):24-
Introduction:
Large, rapidly enlarging adrenal masses typically mandate
surgical intervention given the high probability of adrenocortical carcinoma (ACC). However, benign processes can mimic these aggressive growth kinetics, creating a
diagnostic challenge for clinicians.
Case:
A 74-year-old male with hypertension, atrial fibrillation on
rivaroxaban, and prostate cancer was referred for evaluation
of a right adrenal incidentaloma detected on computed
tomography imaging performed for prostate cancer
staging. The well-defined mass measured 8.9 × 7.8 × 7.5 cm
(AP × W × CC) with areas of calcification. Mean attenuation
was +40 Hounsfield Unit, with no significant washout.
Biochemical evaluation confirmed a non-functioning
lesion (24-hour urine metanephrines 756 mcg/24 hours
[N 246–753 mcg/24 hours]; serum cortisol 62 nmol/L post
overnight dexamethasone suppression test). The patient was otherwise asymptomatic and declined surgical intervention. Repeat imaging 4 months later demonstrated
interval enlargement of the mass to 9.8 × 8.8 × 10.7 cm. Due
to this rapid growth, which was highly concerning for ACC,
the patient underwent laparoscopic right adrenalectomy.
Histopathological examination unexpectedly revealed
an adrenal hematoma without evidence of an underlying
tumor or malignancy.
This case illustrates the difficulty in differentiating
aggressive cortical tumors from atypical hemorrhagic
events. Larger series on adrenal hemorrhage reported
trauma and procedural complications as the leading causes,
with a median size of 3–4 cm. Idiopathic large adrenal
hematomas presenting as rapidly expanding “pseudotumors” are exceptionally rare, with fewer than 20 cases
reported in which surgical resection was performed due to
high preoperative suspicion of malignancy. Additionally,
adrenal hemorrhage attributed to anticoagulant therapy
often occurs bilaterally. Unilateral lesion, especially when
large, can pose a diagnostic challenge as highlighted in
this case.
Conclusion
In patients on anticoagulation, rapid interval growth of
an adrenal mass does not always equate to malignancy.
Recognizing this mimicry in the era of widespread Direct
Oral Anticoagulant use is essential for refining treatment
decision regarding surgical intervention, as most cases exhibited a self-limiting process with spontaneous resolution.

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):40-
Introduction:
The increasing prevalence of diabetes represents a
significant global health challenge. Modifiable risk factors,
including physical inactivity, unhealthy dietary habits, and obesity contribute substantially to this rising burden.
In conjunction with the 2025 World Diabetes Day (WDD)
campaign focusing on “diabetes and the workplace,” we
assessed diabetes risk among healthcare workers in our
hospital using the Modified Asian Finnish Diabetes Risk
Score (ModAsian FINDRISC).
Methodology:
Healthcare workers from various departments were invited
to participate in the hospital WDD celebration. A total of
286 attendees underwent anthropometric measurements
and completed the ModAsian FINDSRIC questionnaire.
Descriptive statistics were used to summarize the
prevalence of risk factors and overall diabetes risk.
Results:
The participants included doctors, nurses, allied healthcare
professionals, as well as hospital support and administrative
staff. The majority of participants (74.8%) were aged below
45 years. 39.2% were overweight while 30.8% were obese.
One-third (37.4%) had increased waist circumference
(WC) (≥90 cm for men, ≥80 cm for women). Additionally,
20% of respondents reported being on antihypertensive
medication, and 23.8% had previously recorded high blood
glucose. A family history of diabetes mellitus (DM) was
reported by 62.6% of respondents. Additionally, about onethird were sedentary with less than 30 minutes of daily
exercise or physical activity, another one-third did not
consume fruits or vegetables on a daily basis. The median
ModAsian FINDRISC score was 8, with approximately
30% of them classified as having moderate to very high
risk of developing DM (moderate: 17.5%; high: 10.8%; very
high: 2.8%).
Conclusion
These results revealed high metabolic risk in healthcare
workers and highlight the need for targeted workplace
health promotion strategies to reduce the risk of developing
diabetes.

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):42-43
Introduction:
The 2021 IDF-DAR risk calculator had been previously
evaluated in multiple studies and subsequently widely
accepted and applied in clinical practice as a practical
standardized tool for patient risk stratification. Recently
updated, the 2026 IDF-DAR Risk calculator enables a more individualized, evidence-related evaluation of patientrelated and disease-related risk factors, incorporating
modern diabetes technologies, including continuous
glucose monitoring (CGM), automated insulin delivery
(AID) systems, and advanced insulin formulations to
enhance risk stratification. This tool allows medical
professionals to tailor Ramadan practices based on overall
factors toward promoting safe fasting.
Methodology:
This prospective multicentre observational study recruited
adults with Type 1 and Type 2 diabetes attending public
hospitals nationwide. People with diabetes (PwD) intending
to perform Ramadan fasting were invited to participate
and assessed using the 2026 IDF-DAR Risk Calculator in
the 6-week pre-Ramadan period between 30th January and
19th March 2026.
Results:
A total of 458 PwD were evaluated and stratified into low
(15.7%), moderate (41%), and high risk (43.3%) categories.
Most participants had Type 2 diabetes (83.6%), with 60.3%
having a disease duration exceeding 10 years and 43%
exhibiting poor glycemic control (hemoglobin A1c >9%).
Insulin therapy was used by 76.4% of participants, including
two individuals with Type 1 diabetes using AID systems.
Most participants reported no recent hypoglycemia (76.4%),
81.0% performed glucose monitoring, and 3.3% used CGM.
Severe comorbidities were uncommon, with 1.1% having
unstable macrovascular disease and 4.4% advanced chronic
kidney disease (estimated glomerular filtration rate <30).
Notably, 72.2% received structured Ramadan education.
Conclusion
Majority of PwD attending tertiary diabetes clinics were
in the moderate- to high-risk category and intended to
fast despite medical advice against fasting in some cases.
Although most participants were on insulin therapy,
hypoglycemia was low in the pre-Ramadan period.
Integration of modern technologies, advanced insulin
therapies, and structured education may support safer
fasting practices.

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):55-
Introduction:
Repaglinide, a meglitinide analogue, has a rapid onset
and short duration of action. It offers prandial glucose
control while reducing hypoglycemia risk compared to
sulfonylureas. We describe its use in our special cohorts
of diabetic patients where repaglinide was prescribed to
reduce hypoglycemia in vulnerable patients or to optimize
glycemic control through pharmacotherapy intensification
or deintensification.
Cases:
Cohort A comprised 12 elderly patients with multiple
comorbidities (mean age: 70.3 years; mean DM duration:
18.3 years) characterized by high glucose variability and
problematic hypoglycemia. In seven patients, low-dose
gliclazide was replaced with repaglinide with reduction
in hypoglycemic episodes. One patient on low-dose premixed insulin was successfully switched to preprandial
repaglinide. Two patients on basal insulin were able to
reduce their insulin requirements and stabilize their glucose
levels. A younger patient with autonomic dysfunction had
hypoglycemia while on insulin glulisine, while its omission
led to severe hyperglycemia. Substituting glulisine with
repaglinide resolved the glucose variability. Repaglinide
effectively reduced hypoglycemic episodes while maintaining glycemic stability, with a mean hemoglobin A1c
(HbA1c) reduction of 0.36% over 3–6 months.
Cohort B consisted of six younger patients (mean age: 35.3
years) with focus on optimizing HbA1c and improving
treatment adherence. Two patients on basal-bolus regimes
success-fully transitioned off bolus insulin to repaglinide,
significantly improving compliance. One patient on
basal insulin was successfully transitioned to an all-oral
regimen. Three patients on existing oral hypoglycemic
agents were started on repaglinide to close the glycemic
gap. Cohort B achieved a robust mean HbA1c reduction of
2.1% within 3–6 months.
Conclusion
Repaglinide remains an important armamentarium in
personalized diabetes management. Its pharmacokinetics
and flexible dosing allow intensification of glycemic
control while minimizing the risk of hypoglycemia. It also
offers a viable strategy for selected patients struggling
with complex insulin regime.

Acta Parasitologica et Medica Entomologica Sinica 2026;33(2):108-113
Objective This study aimed to investigate the seasonal variation of mosquitoes in Yantai, Shandong Province, and provide a scientific basis for mosquito and mosquito-borne disease control. Methods From March to November for each of the years between 2020 and 2023, adult mosquitoes were collected from different habitats, including parks, hospitals, urban residential areas, rural households and livestock sheds, in 13 counties of Yantai City using a mosquito trap lamp method, among which, female mosquitoes were separated and identified, and the numbers were counted. We used the circular distribution method to analyze the temporal distribution characteristics of mosquito density. Results The γ values obtained for mosquitoes in Yantai from 2020 to 2023, the distribution of mosquitoes in different habitats, and dominant mosquito species in different months showed strong seasonality, with values ranging from 0.7461 to 0.8531(P < 0.05). The peak period of seasonal variation in mosquitoes occurred from June 28thto September 13th, with August 5thbeing identified as the peak day. The peak periods of seasonal variation in mosquitoes in residential areas, parks, hospitals, peasant households, and animals sheds were observed from June 24thto September 14th, June 25thto September 10th, June 22ndto September 12th, July 1stto September 9th, and July 2ndto September 17th, respectively, with corresponding peak days on August 4th,3rd, 2nd, 5th, and 9th, respectively. The peak periods of Culex pipiens pallens, Aedes albopictus, and Anopheles sinensis were from June 26thto September 11th, June 28thto September 17th, and July 12thto September 17th, respectively, with corresponding peak days on August 3rd,7th, and 14th, respectively. Conclusions Our findings in this study revealed that the peak of mosquito activity in Yantai was concentrated in early August, with a peak period extending from June 28thto September 13th, and there were differences between different habitats(with peak periods for rural households and livestock sheds occurring later than those in residential areas, parks, and hospitals). Moreover, with respect to the mosquito species, populations of Cx. pipiens pallens and Ae. albopictus peaked earlier than those of An. sinensis. Based on these findings, we recommend that city-wide mosquito control work should commence in late June, and include appropriate early prevention and control measures for key habitats, such as livestock sheds, and dominant mosquito species, such as Cx. pipiens pallens, to minimize the density of mosquito vectors and the risk of disease transmission.

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):71-
Introduction:
Severe hypercalcemia is most commonly caused by primary
hyperparathyroidism (PHPT) and malignancy. While
standard therapies are effective in most cases, a subset of
patients have persistent or refractory hypercalcemia. We
present a retrospective case series detailing the clinical
characteristics, biochemistry, and outcomes of patients
treated with denosumab for hypercalcemia.
Cases:
Seven patients with severe hypercalcemia were identified,
comprising five with PHPT and two with malignancyassociated hypercalcemia. The mean age was 70.4 years
(range 55–86), with 71% female (n = 5) and 29% male (n
= 2). Baseline corrected calcium ranged from 2.92 to 4.59
mmol/L, with a mean of 3.26 mmol/L. In the PHPT cohort,
parathyroid hormone (PTH) levels were significantly
elevated (16.7–168 pmol/L), while malignancy patients had
suppressed PTH (0.6 and 0.9 pmol/L).
Prior to denosumab, 4/7 patients (57%) received bisphosphonates, 3/7 (43%) received calcitonin, and 1/7 (14%) was
treated with cinacalcet. Denosumab resulted in a mean
reduction in corrected calcium of 0.22 mmol/L from 3.26
to 3.03 mmol/L.
Biochemical response was observed in 5/7 patients (71%).
Of these, 3 patients (43%) achieved normocalcemia,
while 2 patients (29%) demonstrated a partial response.
The remaining 2/7 patients (29%) showed no significant
improvement in calcium levels. Among responders, the
mean time to calcium reduction to <3.0 mmol/L was 27 days
(range 7–47). Repeat dosing was required in the majority
of patients, with a mean of 1.7 doses per patient (range
1–4), indicating variability in both onset and durability
of response. Among patients with PHPT, four underwent
parathyroidectomy, and one declined surgery. Both patients
with malignancy were managed nonsurgically.
Conclusion
Denosumab achieved normocalcemia in 43% of patients,
with additional partial responses. Its effects were variable,
with delayed response and frequent need for repeat dosing,
supporting its role as an adjunctive or bridging therapy
rather than as a definitive treatment.

9.Fatal Hypercalcemic Crisis Secondary to Primary Hyperparathyroidism: A Case Report
Pey Hui See ; Ee Wen Loh ; Pei Lin Chan ; Florence Hui Sieng Tan
Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):75-
Introduction:
Hypercalcemic crisis, a decompensated state characterized
by multiorgan dysfunction and a corrected serum calcium
(CCa) level typically >3.5 mmol/L, is a rare but lifethreatening endocrine emergency that requires prompt
recognition and aggressive multimodal management. We
report a fatal case of hypercalcemic crisis secondary to
primary hyperparathyroidism, which was refractory to
multiple lines of medical therapy.
Case:
A 55-year-old female with diabetes mellitus, hypertension,
and chronic kidney disease (creatinine 159 umol/L; estimated glomerular filtration rate 33 mL/min) presented with
3 days of confusion, profound fatigue, and constipation,
preceded by a 1-month history of polyuria and polydipsia.
Her Glasgow Coma Scale (GCS) was E4V3M5. Physical
examination was unremarkable, with no palpable neck
swelling. Significant laboratory findings included severe
hypercalcemia with markedly elevated serum intact
parathyroid hormone (iPTH) (CCa 4.49 mmol/L; phosphate
1.01 mmol/L; iPTH 60.1 pmol/L [N 1.6–6.0]; creatinine
149 umol/L). Saline diuresis was initiated together with
subcutaneous calcitonin, resulting in an initial biochemical
response, with CCa decreasing to a nadir of 3.61 mmol/L.
However, the CCa subsequently rebounded to 5.00 mmol/L.
Hemodialysis was performed, followed by administration
of subcutaneous denosumab 60 mg. Nonetheless, the CCa
decreased only modestly to 4.28 mmol/L. She became
increasingly drowsy, and her clinical course was further complicated by aspiration pneumonia and lung collapse,
leading to respiratory failure requiring intubation and
inotropic support. Despite intensive care, additional
sessions of hemodialysis and continuous renal replacement
therapy, her CCa remained persistently above 4.0 mmol/L,
peaking at 5.35 mmol/L. Due to her critical condition,
imaging for lesion localization could not be performed.
She eventually succumbed to her illness on day 10 of
admission, before definitive surgery could be undertaken.
Conclusion
This case highlights the potentially fatal course of
hypercalcemic crisis secondary to primary hyperparathyroidism. The reported mortality rate is high, at around
60%. Early recognition and intensive management,
including emergency parathyroidectomy in resistant cases,
have been shown to be crucial in improving outcomes.

10.A Diagnostic Dilemma in Ectopic ACTH Syndrome: When Biochemistry and Imaging Conflict
Ioanna Ting Yung Sim ; Florence Hui Sieng Tan ; Sing Yee Sim ; Pei Lin Chan ; Ee Wen Loh
Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):83-84
Introduction:
Ectopic ACTH secretion (EAS) is a rare cause of Cushing’s
syndrome, accounting for 5–15% of cases. Pulmonary
neuroendocrine tumors are the most frequent cause.
However, primary tumor localization remains a significant
diagnostic challenge, delaying effective treatment.
Case:
A 59-year-old female with diabetes mellitus presented
with refractory hypertension and hypokalemia. Initial
laboratory findings revealed a baseline cortisol of 1,164
nmol/L and morning adrenocorticotropic hormone
(ACTH) of 19.5 pmol/L (normal <10.2 pmol/L), with an
overnight dexamethasone suppression test cortisol of
624 nmol/L. Pituitary magnetic resonance imaging (MRI)
and computed tomography (CT) scans of the thorax,
abdomen, and pelvis were initially unremarkable. A PET
scan identified mild hypermetabolism in the left adrenal
gland and gastrointestinal tract, though colonoscopy
revealed only chronic colitis. An intravenous desmopressin
stimulation test demonstrated a 181% rise in ACTH and a
35% rise in cortisol, pointing toward pituitary Cushing’s.
However, repeat pituitary MRI remained normal.
A high-dose dexamethasone suppression test showed
approximately 34% cortisol suppression (cortisol 1,128
nmol/L to 745 nmol/L), suggesting ectopic Cushing’s
syndrome. Bilateral inferior petrosal sinus sampling
demonstrated a peak central-to-peripheral ACTH ratio of
1.8 on the right and 1.6 on the left, pointing toward ectopic
Cushing’s.
Localization with DOTATATE PET-CT identified a 7 × 9 ×
8 mm nodule in the right middle lobe. A wedge resection
was performed. Histopathology confirmed a typical
carcinoid tumor with clear resection margins. Immunohistochemistry revealed tumor cells positive for CK AE1/ AE3, synaptophysin, chromogranin, and INSM-1, with
weak positivity for ACTH. The latest 8 am cortisol was 117
nmol/L and ACTH 1.74 pmol/L, confirming biochemical
cure. Hypokalemia resolved, with improvement in her
metabolic profile.
Conclusion
This case highlights the diagnostic complexities of EAS,
particularly when initial imaging is inconclusive and
biochemical tests yield conflicting results. Timely, precise
localization of the causative tumor is crucial for successful
surgical intervention and to prevent severe complications
of hypercortisolism, thereby improving patient outcomes.
