OBJECTIVES
Clinical pathways (CPs) ensure adherence to heart failure (HF) management guidelines. To optimize quality care in a low resource setting, an evidence-based care pathway for the management of acute HF was implemented at the emergency department (ED) of the Philippine General Hospital (PGH), the designated national tertiary hospital and referral center. This study aimed to describe the characteristics of adults with acute HF admitted at the ED and evaluate the quality of care they received, measured using physician adherence to the hospital’s acute heart failure CP.
METHODSThis was a retrospective, descriptive cohort study. We reviewed the inpatient charts of all adult patients with acute HF admitted to the ED of the PGH and referred to the Division of Cardiovascular Medicine between December 1, 2022 and May 31, 2023. Quality of care was assessed based on adherence to quality indicators adapted from routine and conditional order sets detailed in the pathway. Descriptive statistics was utilized to describe patient characteristics, quality of care, and outcomes.
RESULTSTwo hundred thirty-six (236) patients were included, with a mean age of 51.8 years. Majority were male (53.4%); hypertension (61.4%) and ischemic heart disease (53.8%) were the most common comorbidities, and infection the most common precipitant of decompensation (60.6%). There were optimal adherence rates to routine orders, which included referrals to Internal Medicine and Cardiology, baseline vital signs monitoring, fluid intake and output monitoring, chest radiograph, complete blood count, blood urea nitrogen, sodium, potassium, prothrombin time, partial thromboplastin time, arterial blood gas, urinalysis, and N-terminal pro b-type natriuretic peptide. Conditional orders, such as oxygen support, focused echocardiography, thyroid - stimulating hormone, and the use of vasopressors, diuretics, and venous thromboembolism prophylactic agents, were optimally performed when warranted. However, we noted suboptimal adherence to certain resource-intensive conditional orders, such as hourly monitoring of urine output (61.4%), hooking to cardiac monitor (53.8%), and performance of 12-lead ECG within 10 minutes (56.8%). Further, only 43.9% of patients were referred to the intensive care unit. Troponin I, calcium, magnesium, and albumin were ordered in excess.
CONCLUSIONOverall adherence rate of physicians to the hospital’s Acute Heart Failure Pathway was satisfactory. Work is needed to improve adherence to hourly urine output monitoring, consistent hooking to cardiac monitor, and timely performance of 12-lead ECG – an effort that begins with expanding in-hospital diagnostic equipment and human resource supply. We recommend continuous pathway implementation with periodic evaluation and stakeholder feedback to further improve quality of care.

OBJECTIVES
In Asia, younger individuals (below age 45) are diagnosed to have type 2 diabetes with increased rates of obesity defined by lower BMI yet with greater visceral adiposity (waist circumference and waisthip ratios). The prevalence data on type 1 diabetes is not well established, considered to be low, but is seen to be increasing as well. This changing phenotype therefore, presents a clinical dilemma in terms of correctly classifying diabetes and deciding on the consequent appropriate treatment. Distinguishing type 1 from type 2 diabetes has become more difficult with type 2 diabetes dramatically increasing in young adults and children. This study aims to define the characteristics of diabetes among young adults in the Philippines to provide a basis for appropriate management amidst changes in diabetes phenotypes seen globally.
METHODSIn this cross-sectional analytic study, we characterized the demographic, metabolic, and autoimmune features of diabetes among young adult Filipinos aged 18 to 45 years old consulting at a tertiary referral center in Manila, Philippines. Baseline serum A1c, FBS, 75-g oral glucose tolerance test, insulin, serum C-peptide, insulin autoantibodies, leptin, adiponectin, lipid profile, and thyroid function tests were obtained from the participants and analyzed. The homeostasis model assessment (HOMA) was used to estimate the insulin sensitivity.
RESULTSA total of 348 patients with diabetes were included, with females comprising two-thirds of the participants. The mean age at diagnosis of diabetes was 35.9±7.22 years. The mean BMI was 28.12 kg/m2, with median waist to hip ratio (WHR) of 0·93. Metabolic syndrome was found in 60% of participants and 67.82% were obese by body mass index. The mean A1c was 9.07±2.52%. Good glucose control (A1c less than 7.0%) was seen in 23% of participants while nearly half (48%) had HbA1c which was >9.0%. The median levels of fasting insulin and C-peptide were 12.62 (range 1.33–90.42) mIU/L and 0.78 ng/mL (range 0–16.2), respectively.
Included participants were diagnosed with diabetes within a year and as such, majority did not have any micro- or macrovascular complications. The most common diabetes complication was sensory neuropathy detected by monofilament testing, which was found in 28% of participants, followed by non-proliferative diabetic retinopathy in 13%. A history of previous diabetic ketoacidosis was found in 10 patients (2.87%). Glutamic acid decarboxylase (GAD) and insulin auto-antibodies were found in 3.2% and 19.3% of participants, respectively. Approximately half (51.73%) of the participants were insulin resistant by HOMA-IR.
CONCLUSIONIn contrast with Caucasians and other Asians, diabetes among young Filipino adults is associated with lower BMI but with a similarly high visceral adiposity as shown by an elevated WHR. Metabolic syndrome with insulin resistance as defined by a variety of indices is predominant. Type 1 diabetes with autoantibodies occur in only a small fraction of this population. Data derived from this work can provide a framework for cluster analysis towards personalized management specific to this population.

Introduction:
Medullary thyroid carcinoma (MTC) comprises sporadic and hereditary forms, the latter commonly associated with
multiple endocrine neoplasia type 2 (MEN2) which is identifiable through genetic screening of germline RET protooncogene. We compared the clinicopathological features and outcomes of hereditary and sporadic MTC in our single
centre.
Methodology:
We conducted a retrospective audit of patients with MTC from 2000 to 2026. Patients were classified as either hereditary
or sporadic based on genetic testing and/or family history of MTC/MEN2A syndrome. Variables analyzed included age
at diagnosis, mode of presentation, pre-operative calcitonin, tumor size, lymph node (LN) involvement, post-operative
biochemical cure, repeat surgery and presence of structural residual/recurrent disease.
Results:
A total of 57 patients were included (18 hereditary [31.6%], 39 presumed sporadic [68.4%]) with a median follow-up of
7.5 years (IQR 1.5–12.4). Hereditary MTC was diagnosed at a significantly younger age than sporadic MTC (33.0 vs. 44.7
years, p = 0.010) where 33% of the cases were diagnosed via screening detection whereas sporadic MTC more commonly
presented with symptomatic neck swelling (84.6% vs. 50.0%, p = 0.008). There were no significant differences in median
pre-operative calcitonin (513.5 vs. 1148.0 pg/mL, p = 0.101), tumor size (24.5 vs. 22.5 mm, p = 0.301), or LN involvement
(41.7% vs. 61.5%, p = 0.307) between hereditary and sporadic MTC. Long-term outcomes were also comparable, with
no differences in biochemical status, need for repeat surgery or residual/recurrent structural disease.
Conclusion
Hereditary MTC presents earlier and is more frequently detected due to screening, whereas sporadic MTC often presents
symptomatically. Long-term outcomes are not primarily determined by hereditary status alone. Early access to RET
mutation testing with a view to initiating prophylactic treatments rather than post detection surgery may improve
disease burden.

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):45-
Introduction:
Type 2 diabetes mellitus (T2DM) and thyroid disorders are
common endocrine conditions with a bidirectional relationship affecting glucose and lipid metabolism. Adiposity,
particularly fat mass index (FMI), may influence thyroid
function. but its association with thyroid dysfunction and
glycemic control remains unclear, especially in Malaysia.
This study aimed to determine the prevalence of thyroid
dysfunction in T2DM and its association with glycemic
control and FMI at Universiti Teknologi MARA (UiTM).
Methodology:
A cross-sectional study was conducted among patients
with T2DM attending the Endocrine Clinic, UiTM, from
December 2025 to March 2026. A total of 91 participants
aged 18–70 years were recruited using convenience
sampling. Demographic, clinical, anthropometric, and
laboratory data were collected. Thyroid dysfunction was
defined as thyroid-stimulating hormone (TSH) <0.38 or
>5.33 mIU/L. Body composition was assessed using the
InBody 380 to determine FMI. Data were analyzed using
SPSS version 30 with descriptive statistics and Pearson
correlation.
Results:
The prevalence of thyroid dysfunction among patients
with T2DM was 7.7% (7/91), predominantly with low
TSH levels. Mean hemoglobin A1c (HbA1c) in the overall
study population was 7.59 ± 1.49%, and mean TSH was
1.42 ± 0.95 mIU/L, within the euthyroid range. Mean FMI
was 11.95 ± 5.23 kg/m², exceeding normal ranges for both
men (3–6 kg/m²) and women (5–9 kg/m²). FMI showed a
positive correlation with TSH level (r = 0.379, p <0.001), indicating that higher adiposity was associated with
higher TSH levels despite remaining within the euthyroid
range. Pearson correlation showed a weak, non-significant
negative correlation between HbA1c and TSH (r = −0.127,
p = 0.229).
Conclusion
The prevalence of thyroid dysfunction among patients with
T2DM in our cohort was relatively low at 7.7%. However,
the significant correlation between FMI and TSH level, even
within the euthyroid range, suggests that adiposity may
exert a clinically relevant influence on thyroid function.

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):66-
Introduction:
Diabetic ketoacidosis (DKA) and thyroid storm are
individually rare but potentially fatal endocrine crises
in pregnancy. Each carries significant maternal and fetal
morbidity, with mortality risk compounded when they
occur concomitantly. Physiological and pharmacokinetic
changes of pregnancy, combined with overlapping
symptoms, necessitate urgent treatment strategies.
Case:
A 29-year-old G2P2 female at 29 weeks’ gestation, with
poorly controlled type 2 diabetes mellitus (hemoglobin
A1c 8.1%) on a basal–bolus insulin regimen and Graves’
disease managed with carbimazole, non-adherent to medications, presented with fever, vomiting, and dyspnea. On
examination, she was tachycardic (HR 138 bpm), hypotensive (BP 94/60 mmHg), and hypoxic. Laboratory investigations revealed hyperglycemia (glucose 27.1 mmol/L), severe metabolic acidosis (pH 7.02, bicarbonate 4.9
mmol/L), and elevated serum ketones (4.6 mmol/L), consistent with DKA. Thyroid function tests showed suppressed
thyroid-stimulating hormone (<0.005 mIU/L) and elevated
free T4 (28.2 pmol/L), with a Burch–Wartofsky score of 70.
Unfortunately, intrauterine fetal demise was confirmed
upon the patient’s presentation to the emergency department. She was intubated and admitted to the intensive care
unit, receiving fluid resuscitation judiciously according to
the DKA regimen, with frequent assessment of volume
status. Intravenous insulin and potassium supplements
were commenced concurrently. Metabolic stabilization was
achieved within 24 hours. Carbimazole, propranolol, Lugol’s iodine, and intravenous hydrocortisone were started
for treatment of thyroid storm. A breech-assisted vaginal
delivery was performed, and her postpartum course was
uneventful.
Conclusion
The case reveals the catastrophic potential of concurrent
DKA and thyroid storm in pregnancy, where rapid
maternal deterioration and poor fetal outcomes can occur
despite timely intervention. High clinical suspicion,
early biochemical confirmation, and coordinated
multidisciplinary management are vital. Precipitating
factors, particularly medication non-adherence, must
be addressed through intensive patient education and
structured follow-up to prevent recurrence.

Journal of Zhejiang University. Medical sciences 2025;54(3):372-381
OBJECTIVES:
To investigate the role of nucleolar pre-rRNA processing protein NIP7 (NIP7) in maintaining the malignant phenotype of anaplastic thyroid cancer (ATC) and its molecular mechanisms.
METHODS:
NIP7 expression in ATC tissues and its gene knock-out effects in ATC cells were analyzed using gene expression microarray (GSE33630), proteome database (IPX0008941000) and the Dependency Map database, respectively. Expression and localization of NIP7 in normal thyroid cells, papillary thyroid cancer cells, and ATC cells were detected by Western blotting. Small interfering RNA (siRNA) was transfected into ATC cells, and the knockdown efficiency of NIP7 was detected by quantitative reverse transcription polymerase chain reaction (qRT-PCR) and Western blotting. Cell proliferation was assessed by CCK-8 assay, colony formation was evaluated by colony formation assay, and tumor growth was assessed by xenograft tumor model in nude mice. SUnSET (surface sensing of translation) assay combined with co-immunoprecipitation were employed to evaluate the effect of NIP7 silencing on ubiquitin-conjugating enzyme E2 C (UBE2C) translation. Finally, gene set enrichment analysis was used to identify shared pathways of NIP7 and UBE2C, which were validated by qRT-PCR.
RESULTS:
Compared with normal tissues and papillary thyroid cancer, NIP7 was significantly upregulated in ATC tissues, and had a gene knock-out fitness effect on different ATC cell lines. The relative protein levels of NIP7 in ATC cells were significantly higher than those in normal thyroid follicular cells, and the protein was mainly expressed in the nucleus. NIP7 silencing significantly inhibited cell proliferation and reduced colony formation. Xenograft tumor model showed that NIP7 knockdown significantly slowed down the growth of ATC xenograft, and the tumor volume and weight were significantly lower than those in the control group (all P<0.05). NIP7 silencing downregulated the protein level of UBE2C, but did not affect the expression of UBE2C mRNA. Compared to the control group, UBE2C silencing significantly inhibited ATC cells proliferation (P<0.01) and colony formation (P<0.05). UBE2C overexpression reversed the proliferation-inhibitory effect induced by NIP7 silencing (P<0.01). Gene set enrichment analysis indicated that NIP7 and UBE2C were both involved in DNA replication. NIP7 or UBE2C silencing could significantly downregulate the expression levels of DNA polymerase epsilon, catalytic subunit 2 and replication factor C4 in DNA replication pathway.
CONCLUSIONS
NIP7 promotes ATC tumor growth by upregulating UBE2C to mediate DNA replication.

OBJECTIVE:
By analyzing the hormone secretion of the adenohypophysis, thyroid glands, gonads, and adrenal cortex in patients with hematological diseases before and after hematopoietic stem cell transplantation (HSCT), this study aims to preliminarily explore the effect of HSCT on patients' hormone secretion and glandular damage.
METHODS:
The baseline data of 209 hematological disease patients who underwent HSCT in our hospital from January 2019 to December 2023, as well as the data on the levels of hormones secreted by the adenohypophysis, thyroid glands, gonads and adrenal cortex before and after HSCT were collected, and the changes in hormone levels before and after transplantation were analyzed.
RESULTS:
After allogeneic HSCT, the levels of thyroid-stimulating hormone (TSH), triiodothyronine (T3), free triiodothyronine (FT3) and estradiol (E2) decreased, while the levels of luteinizing hormone (LH) and follicle- stimulating hormone (FSH) increased. The T3 level of patients with decreased TSH after transplantation was lower than that of those with increased TSH after transplantation. In female patients, the levels of prolactin (PRL), progesterone (Prog), and testosterone (Testo) decreased after HSCT. Testo and PRL decreased when there was a donor-recipient sex mismatch, and the levels of adrenocorticotropic hormone (ACTH) and cortisol (COR) decreased when the HLA matching was haploidentical. The levels of T3, FT3, and PRL decreased after autologous HSCT. In allogeneic HSCT patients, the levels of TSH, T4, T3, FT3, and ACTH in the group with graft-versus-host disease (GVHD) were significantly lower than those in the group without GVHD. Logistic regression analysis showed the changes in hormone levels after transplantation were not correlated with factors such as the patient's sex, age, or whether the blood types of the donor and the recipient are the same.
CONCLUSION
HSCT can affect the endocrine function of patients with hematological diseases, mainly affecting target glandular organs such as the thyroid, gonads, and adrenal glands, while the secretory function of the adenohypophysis is less affected.

OBJECTIVES:
Lymph node metastasis in papillary thyroid cancer (PTC) is closely associated with tumor recurrence and patient survival. However, current technologies have limited sensitivity in detecting occult cervical lymph node metastases. Identifying accurate molecular markers for predicting PTC metastasis holds significant clinical value. This study aims to analyze WNT10A expression in PTC and its clinical significance, and to explore the role of WNT10A gene knockdown in PTC cell proliferation, invasion, and metastasis.
METHODS:
The expression of WNT10A in thyroid carcinoma was analyzed using the Gene Expression Profiling Interactive Analysis (GEPIA) and University of Alabama at Birminghara Cancer data analysis Portal (UALCAN) databases. Real-time RT-PCR was used to measure WNT10A mRNA levels in tumor and adjacent normal tissues from 32 PTC patients. Immunohistochemistry was conducted on 158 PTC specimens to assess WNT10A protein expression and its correlation with clinicopathological features. In vitro experiments were performed using K1 and TPC-1 cell lines. Cell proliferation was assessed using the Celigo system and methyl thiazolyl tetrazolium (MTT) assays; apoptosis was measured via flow cytometry; invasion and metastasis were evaluated using scratch and Transwell assays. A xenograft model was established in nude mice to observe tumor growth, and tumor weight and volume were compared between cell lines. Differentially expressed genes regulated by WNT10A were identified via mRNA sequencing, followed by Gene Ontology (GO) and ingenuity pathway analysis (IPA). Real-time PCR and Western blotting were used to validate the effects of WNT10A on key downstream mRNA and protein in the Tec kinase signaling pathway.
RESULTS:
WNT10A mRNA expression was significantly higher in thyroid cancer tissues compared to adjacent normal tissues according to GEPIA and UALCAN (both P<0.01). The real-time RT-PCR result showed that WNT10A mRNA expression in PTC tissues was high than that in adjacent tissues (P<0.01). Immunohistochemistry revealed significantly higher WNT10A protein expression in PTC tissues compared to adjacent tissues (P<0.01), and its expression correlated with multifocality, extrathyroidal invasion, and lymph node metastasis. WNT10A knockdown significantly inhibited proliferation, altered cell cycle distribution, and increased apoptosis in K1 and TPC-1 cells (all P<0.01). WNT10A silencing also reduced migration and invasion abilities in both cell lines. In vivo, WNT10A knockdown in TPC-1 cells suppressed tumor formation in nude mice. GO analysis and IPA suggested that the Tec kinase signaling pathway was a key downstream target of WNT10A. RT-PCR and Western blotting confirmed that WNT10A knockdown downregulated the expression of key genes (STAT3, MAPK8, TNFRSF21, and AKT2) in this pathway.
CONCLUSIONS
WNT10A is highly expressed in PTC and is associated with tumor proliferation, invasion, and metastasis. Its tumor-promoting effects may be mediated through suppression of the Tec kinase signaling pathway.

Journal of Central South University(Medical Sciences) 2025;50(5):815-826
OBJECTIVES:
Increasing detection of low-risk papillary thyroid carcinoma (PTC) is associated with overdiagnosis and overtreatment. N6-methyladenosine (m6A)-mediated microRNA (miRNA) dysregulation plays a critical role in tumor metastasis and progression. However, the functional role of m6A-miRNAs in PTC remains unclear. This study aims to elucidate the regulatory mechanism of m6A-miR-139-5p expression in PTC, determine its association with PTC metastasis, and evaluate its potential as a diagnostic biomarker for PTC metastasis, thereby providing experimental evidence for precision diagnosis and therapy.
METHODS:
Expression profiles of m6A-miRNAs were compared between the The Cancer Genome Atlas (TCGA) and GSE130512 cohorts to identify metastasis-associated candidates. Clinical specimens from 13 metastasis and 18 non-metastasis PTC patients were analyzed to assess m6A-miR-139-5p expression and its correlation with metastasis. Functional experiments were conducted to investigate the effect of fat mass and obesity-associated protein (FTO) on pri-miR-139 methylation and processing, clarifying its regulatory role in miR-139-5p expression. In TPC-1 cells, MTT assays were performed to evaluate whether miR-139-5p overexpression could counteract FTO-mediated cell proliferation. Transwell invasion assays were used to determine the impact of miR-139-5p on PTC cell invasion, exploring whether it functions through the ZEB1/E-cadherin axis.
RESULTS:
By comparing TCGA and GSE130512 cohorts, it was found that circulating m6A-miR-139-5p could serve as a biological indicator for detecting PTC metastasis. Detection of 13 metastatic and 18 non-metastatic clinical specimens showed that FTO inhibited the processing of pri-miR-139 by reducing its methylation level, leading to the dysregulation of miR-139-5p in PTC (P<0.05). In TPC-1 cells, MTT assay showed that overexpression of miR-139-5p could partially reverse FTO overexpression-mediated cell proliferation (P<0.05). In addition, miR-139-5p inhibited the invasive ability of PTC cells by targeting the ZEB1/E-cadherin axis, while FTO overexpression could partially weaken this inhibitory effect.
CONCLUSIONS
Circulating miR-139-5p can be a potential marker for evaluating PTC metastasis. FTO affects the expression and function of miR-139-5p by regulating m6A modification of pri-miR-139, but its clinical value needs further verification.
