OBJECTIVES

In the past decade, the prevalence of diabetes in the Philippines has been increasing. The prevalence of diabetes is 7.1% and it is the sixth leading cause of death among adults. Preventive measures to address the incidence of diabetes, as well as diabetes-related complications, have been in place. However, knowledge of the risk factors for developing cardiovascular or renal-related Type 2 Diabetes Mellitus (T2DM) complications has numerous benefits for T2DM patients. This study aimed to describe common risk factors among Filipino T2D patients which increase their risk of developing cardiorenal complications including Heart Failure and CKD. Furthermore, the study aimed to assess the
awareness of T2DM patients regarding these risk factors

METHODS

A clinic-based cross-sectional survey among Filipinos with T2DM Philippines was conducted in the different regions in the Philippines from April 2021 to January 2022. The study participants were 16,268 patients of various ages and sex, however, only 11,578 of them answered the form completely. The patients and their corresponding physicians answered a validated self-assessment form on whether they had 8 identified risk factors for T2DM.

RESULTS

This survey identified Hypertension as the most common risk factor present in 96.49% of T2DM patients followed by Dyslipidemia (82.56%), Family History of CVD (77.11%), Obesity (59.66%), Kidney Disease (38.08%), Personal History of CVD (36.22%), Smoking (35.49%) and Family History of Kidney Disease (33.05%). Most patients were aware of the presence of these risk factors. However, there were some identified by the physician but unknown to the patient. In decreasing order of frequency, these were personal history of heart and blood vessel diseases (7.19%), followed by family history of kidney disease (5.44%) and smoking (5.1%).

CONCLUSION

This survey was able to identify crucial risk factors in developing T2DM complications that are most common among T2DM patients in the Philippines. Furthermore, for the first time, the study was able to show the level of awareness of T2DM patients regarding the risk factors that they have in developing these complications. These data show the importance of determining and addressing the common risk factors in preventing T2DM complications. Moreover, identification of these risk factors is an important step in prevention of cardiorenal complications.

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.

METHODS

In 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.

RESULTS

A 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.

CONCLUSION

In 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.

WAGR syndrome is a rare congenital disorder, occurring in approximately 1 in 500,000 to 1,000,000 individuals, often presenting with ocular malformations such as aniridia. Glaucoma frequently develops when the iris and angle structures are affected, posing a significant risk of vision loss. We report a one-year and seven-month-old patient who presented with corneal opacity of the left eye. Examination revealed corneal opacity, aniridia, and markedly elevated intraocular pressure of 65 mmHg, while the fellow eye, also with aniridia, was normotensive. The patient underwent immediate combined trabeculectomy-trabeculotomy. Postoperative follow-up and timely management of complications allowed acceptable pressure control over one year, though visual prognosis remained guarded. This case highlights the challenges of managing glaucoma in WAGR syndrome, particularly in resource-limited settings. Medical therapy alone is often insufficient, making surgical intervention essential. Combined trabeculectomytrabeculotomy proved effective in maintaining pressure control when glaucoma drainage devices were not feasible. Multiple interventions and close monitoring are frequently required due to the risk of scarring and postoperative complications. Our experience emphasizes the need for a multidisciplinary ophthalmology approach to optimize outcomes. Despite pressure control, visual outcomes often remain poor due to structural anomalies and the challenges inherent to pediatric patients with this rare syndrome.

OBJECTIVES: To explore the therapeutic mechanism of Chaihu Shugan (CHSG) Decoction for improving cognitive impairment in rats with epilepsy induced by lithium chloride and pilocarpine. METHODS: Male SD rat models of cognitive impairment model after epilepsy induced by intraperitoneal injection with lithium chloride and pilocarpine were randomly divided into 5 groups (n=12) for treatment with daily gavage of saline, donepezil (90 mg/kg), or CHSG Decoction at 2.5, 5.0, 10, 20 and 40 g/kg for 4 consecutive weeks, with 10 rats with intraperitoneal injection with saline as the blank control group. Morris water maze test was used to evaluate cognitive and behavioral changes of the rats after treatment. The mRNA and protein expressions of ASIC1, NR1, NR2A and NR2B in the hippocampus of rats were detected using RT-qPCR and Western blotting. RESULTS: Compared with those with saline treatment, the rat models treated with CHSG Decoction at 5 and 10 g/kg showed significantly shortened escape latency and prolonged stay in the target quadrant with increased number of platform crossings in Morris water maze test. CHSG Decoction treatment at the two doses significantly increased ASIC1, NR1, NR2A and NR2B protein expressions in the hippocampus of the rat models, and their mRNA expression levels were all increased significantly after the treatment at the doses above 2.5 g/kg. CONCLUSIONS CHSG Decoction can improve cognitive impairment in rats after epilepsy possibly by regulating the expression and channel activity of NMDAR protein and its subunit protein via upregulating ASIC1 to modulate neuronal excitability and synaptic plasticity in the hippocampus.

OBJECTIVES: To prepare a stable mouse model of chronic liver fibrosis induced by dietary vitamin A (VA) deficiency combined with CCl₄ injections. METHODS: A total of 126 Balb/c mice were randomized into 3 groups for feeding with a normal VA diet or a VA-deficient diet containing 500 or 200 IU/kg VA. After 4 weeks of feeding, half of the mice in each group were given intraperitoneal injections of 5% CCl₄ (10 mL/kg, twice a week) for 8 weeks. Serum retinol, ALT/AST and liver index of the mice were examined, liver tissue pathologies were observed with HE and Masson staining, and liver fibrosis score and oxidative stress level were evaluated. RESULTS: Four weeks of VA-deficient feeding, especially at 200 IU/kg, significantly lowered serum retinol level of the mice. CCl₄ injections for 8 weeks obviously increased liver index and ALT/AST and caused obvious liver fibrosis in all the mice, but liver pathologies were more severe in the 2 VA-deficient groups; severe liver necrosis with inflammatory cell infiltration was observed in 200 IU/kg VA group, where 2 mice died. After discontinuation of CCl₄, the mice with normal dietary VA showed gradual recovery of the liver index, ALT/AST, liver cord structure and liver fibrosis; the mice with VA deficiency, however, showed no significant improvements in these parameters, and the mice with 200 IU/kg VA still had serious abdominal adhesion, false lobules and massive inflammatory cell infiltration with a fibrosis stage score of 3. The oxidative damage index 8-OHdG was significantly higher in 500 IU/kg VA group than in normal VA group after CCl₄ modeling. CONCLUSIONS Feeding with diet containing 500 IU/kg VA for 4 weeks and 10 mL/kg CCl₄ injections for 8 weeks can result in stable moderate to severe liver fibrosis in mice without spontaneous reversal at 8 weeks of drug withdrawal.

OBJECTIVES: To investigate the effect of serum advanced glycation endproducts (AGEs) on stenosis after first autologous arteriovenous fistula (AVF) in patients with end-stage renal disease (ESRD). METHODS: Patients with ESRD undergoing standard native arteriovenous fistula (AVF) for the first time in the Department of Nephrology, Affiliated Hospital of Guilin Medical University from February to June 2022 were prospectively enrolled. The preoperative general data, clinical examination results and ultrasound data of the operated limbs were collected. The patients with and without stenosis within 2 months after the operation were compared for preoperative serum AGEs levels detected using ELISA and the clinical parameters. Logistic regression analysis was used to analyze the independent risk factors of AVF stenosis, and the sensitivity and specificity of AGEs for predicting postoperative stenosis were analyzed using receiver-operating characteristic (ROC) curve. RESULTS: Of the 94 patients enrolled, 34 had postoperative arteriovenous stenosis and 60 had no stenosis. The number of diabetic patients differed significantly between stenosis group and non-stenosis group (P<0.001). Serum AGEs levels, which were negatively correlated with serum phosphorus level (P<0.05), were significantly higher in stenosis group than in non-stenosis group (Z=-2.837, P=0.005). Serum AGE level was an independent risk factor for postoperative stenosis after AVF (OR=1.251, 95% CI:1.096-1.423, P<0.001). For predicting AVF stenosis, the area under the ROC curve (AUC) of AGEs was 0.677 (P=0.007, 95% CI: 0.572-0.770), with a specificity of 90.00% and a sensitivity of 52.94% at the optimal cut-off value of 8.43 µg/mL; AGEs combined with fibrinogen had an AUC of 0.763 (P<0.001, 95% CI: 0.664-0.844), with a specificity of 73.33% and a sensitivity of 70.59% at the optimal cut-off value of 0.30. CONCLUSIONS Elevated serum AGEs level is an independent risk factor for postoperative AVF stenosis, and its combination with fibrinogen has a better efficacy for predicting postoperative AVF stenosis.

OBJECTIVES: To investigate the incidence of ipsilateral upper urinary tract stones after partial nephrectomy and its risk factors. METHODS: We retrospectively analyzed baseline patient characteristics (age, gender, and body mass index), smoking, alcohol consumption, comorbidities (hypertension, diabetes, hypertriglyceridemia, hyperuricemia, and cardiovascular diseases), preoperative tumor conditions (tumor diameter, multiple foci, location, hemorrhage, necrosis, cystic changes, and endophytic growth), preoperative glomerular filtration rate and intraoperative factors (renal collecting system damage, ischemia time, operation time, surgical approach, and estimated intraoperative blood loss) to identify the risk factors for ipsilateral upper urinary tract stones following partial nephrectomy in our center. RESULTS: The overall incidence of upper urinary tract stones following partial nephrectomy was 7.80% (112/1435). The incidence of ipsilateral upper urinary tract stones was significantly higher than those of contralateral stones (4.95% vs 1.46%, P<0.001) and bilateral stones (4.95% vs 1.39%, P<0.001). Intraoperative damage to the renal collecting system was identified as a significant risk factor for ipsilateral upper urinary tract stones (OR=4.550, 95% CI: 2.237-9.252, P<0.001). Diabetes was a probable risk factor for secondary ipsilateral upper urinary tract stones after partial nephrectomy (OR=2.419, 95% CI: 0.973-6.012, P=0.057). CONCLUSIONS The incidence of ipsilateral upper urinary tract stones after partial nephrectomy is higher than that of contralateral and bilateral stones. Intraoperative renal collecting system damage is a risk factor for secondary ipsilateral upper urinary tract stones after partial nephrectomy.

OBJECTIVES: To analyze the differential expression and biological functions of circRNAs in the anterior lens capsules of high myopic patients with cataract and their pathogenic roles in the development of this condition. METHODS: Anterior lens capsule specimens were collected intraoperatively from 36 patients with age-related cataract (ARC) and 36 high myopic patients with cataract. Among these, 18 specimens from each group were selected for whole transcriptome sequencing and biological analysis, and the remaining 36 specimens were used for validation of circPDGFRA, circFOXJ3, hsa_circ_0004767, hsa_circ_0007528, ciCRIM1, circMAN1A2, circSLC5A3, and circPTK2 expressions using RT-qPCR. hsa_circ_0007528 was selected for cell experiments to examine its effects on proliferation, migration, and apoptosis of lens epithelial cells (LECs). RESULTS: A total of 16 192 circRNAs were detected in the specimens from both groups, among which 62 circRNAs were differentially expressed (29 upregulated and 33 downregulated). GO and KEGG analyses revealed that the differentially expressed circRNAs were primarily localized in the cytoplasm, nucleoplasm, and endoplasmic reticulum, and were involved in signaling pathways associated with Gap junction and the PI3K-Akt, NF-κB, Jak-STAT, HIF-1, and MAPK signaling pathways. The ceRNA network predicted multiple target genes. RT-qPCR validation results were consistent with the sequencing data. In the LECs, upregulation of hsa_circ_0007528 significantly inhibited cell proliferation and migration and obviously promoted cell apoptosis. CONCLUSIONS The expression profile of circRNAs in the anterior lens capsule of high myopic patients with cataract differs from that of ARC patients. Upregulation of hsa_circ_0007528 inhibits LEC proliferation and migration and promotes cell apoptosis.

OBJECTIVES: To develop risk prediction models for postoperative hypothermia after transurethral holmium laser enucleation of the prostate (HoLEP) using machine learning algorithms. METHODS: We retrospectively analyzed the clinical data of 403 patients from our center (283 patients in the training set and 120in the internal validation set) and 120 patients from Weifang People's Hospital (as the external validation set). The risk prediction models were built using logistic regression, decision tree and support vector machine (SVM), and model performance was evaluated in terms of accuracy, recall, precision, F1 score and AUC. RESULTS: Operation duration, prostate weight, intraoperative irrigation volume, and being underweight were identified as the predictors of postoperative hypothermia following HoLEP. Among the 3 algorithms, SVM showed the best precision rate and accuracy in all the 3 data sets and the best area under the ROC (AUC) in the training set and validation set, followed by logistic regression, which had a similar AUC in the two data sets. SVM outperformed logistic regression and decision tree models in the validation set in precision, accuracy, recall, F1 score, and AUC, and performed well in the external validation set with better precision rate and accuracy than logistic regression and decision tree models but slightly lower recall rate, F1 index, and AUC value than the decision tree model. SVM outperformed logistic regression and decision tree models in precision, accuracy, F1 score, and AUC in the training set, but had slightly lower recall rate than the decision tree. CONCLUSIONS Among the 3 models, SVM has the best performance and generalizability for predicting post-HoLEP hypothermia risk to provide support for clinical decisions.

OBJECTIVES: To investigate the effect of intubation with electromyographic (EMG) endotracheal tubes versus conventional wire-reinforced (CWR) tubes on the incidence of postoperative sore throat (POST) in patients undergoing thyroidectomy under general anesthesia and identify the risk factors for POST. METHODS: We retrospectively collected the clinical data from a cohort of 245 patients undergoing elective thyroid surgery under general anesthesia at the Sixth Affiliated Hospital of Sun Yat-sen University between October, 2024 and March, 2025. Patients received intubation with either EMG endotracheal tubes (n=100) or CWR tubes (n=145) during the operation, and the incidences of POST and other postoperative complications were compared between the two groups. Propensity score matching (PSM) was applied to adjust for the baseline differences, and multivariate logistic regression analysis was used to identify independent risk factors for POST. RESULTS: Comparisons of the baseline data revealed significant differences between the two groups (P<0.05). After PSM, 90 patients in EMG group and 75 in CWR group were included in the final analysis with matching baseline characteristics (P>0.05). Post-matching analysis showed that the EMG group had a shorter operative time (P=0.002) but a higher incidence of POST (P=0.001). Multivariate logistic regression identified the use of EMG tubes (OR=17.50, 95% CI: 2.25-136.03, P<0.01) as an independent risk factor for POST. CONCLUSIONS Intubation with EMG endotracheal tubes can shorten the operative time and allow recurrent laryngeal nerve monitoring during thyroidectomy under general anesthesia, but their structural design may increase the risk of POST. Clinical decisions should be made to balance nerve protection and postoperative patient comfort by selecting appropriate tube types and optimizing intubation strategies to enhance perioperative outcomes.
