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.

Abstract Introduction: Type 2 diabetes mellitus (T2DM) is a major global health concern characterized by insulin resistance, hyperglycemia, and chronic inflammation. Interest in natural adjunctive therapies has increased, particularly in mangosteen (Garcinia mangostana), which contains xanthone compounds in the peel with potential antidiabetic properties. Methods: This systematic review followed PRISMA 2020 guidelines. Literature searches were conducted using PubMed, Google Scholar, and ClinicalKey up to December 2022 for studies assessing mangosteen peel extract (MPE) or α-mangostin in diabetic human subjects. Eligible studies included randomized controlled and quasi-experimental trials reporting glycemic or metabolic outcomes. Risk of bias was evaluated using the Cochrane RoB tool. The primary result of this study is to evaluate the effects of mangosteen peel extract supplementation on key glycemic outcomes in patients with T2DM, specifically fasting blood glucose (FBG), HOMA-IR, and HbA1c. Results: A total of two studies (n=2) met the inclusion criteria. A randomized controlled pilot trial reported significant improvement in insulin sensitivity (HOMA-IR −53.2% vs −15.2%; p = 0.004) after 26 weeks of standardized mangosteen extract. A small quasi-experimental study reported a significant reduction in FBG following 7 days of mangosteen peel decoction. Discussion: Limited clinical evidence indicates that mangosteen peel extract may improve insulin sensitivity and lower fasting glucose in T2DM. However, the conclusions are limited by the small number of available studies, the short follow-up duration in one trial, and variability in extract preparation. Conclusion: Mangosteen peel extract demonstrates promising glycemic benefits, including improved insulin sensitivity and reduced fasting glucose. However, the available evidence remains limited by small sample sizes, short follow-up periods, and heterogeneity in extract formulations. Larger randomized controlled trials using standardized preparations are required before clinical recommendations can be made.

Introduction: Insulin resistance and progressive beta-cell dysfunction are key components of the pathophysiology of type 2 diabetes mellitus (T2DM). The triglyceride-to-highdensity lipoprotein cholesterol (TG/HDL) ratio has been widely used as a marker of insulin resistance. In addition, testosterone deficiency has been associated with adverse metabolic profiles and T2DM. However, the relationship between testosterone levels, insulin resistance, and betacell function in patients with T2DM remains incompletely understood. Methodology: A cross-sectional study was conducted involving 25 male patients with T2DM attending the diabetic clinic at Dr. Mohammad Hoesin General Hospital. Serum testosterone, C-peptide, TG, and HDL levels were obtained from routine clinical data. The TG/HDL ratio was calculated as an index of insulin resistance. Normality was assessed using the Shapiro–Wilk test, and due to the non-normal distribution of key variables, Spearman correlation analysis was applied. Results: A strong inverse correlation was observed between testosterone levels and TG/HDL ratio (r = -0.860, p <0.001), indicating that higher insulin resistance was associated with lower testosterone levels. In addition, TG/HDL ratio showed a strong negative correlation with C-peptide levels (r = -0.741, p <0.001), suggesting reduced beta-cell function in the presence of increased insulin resistance. Conclusion In patients with T2DM, increased insulin resistance is strongly associated with lower testosterone levels and reduced beta-cell function. These findings highlight the interaction between metabolic dysfunction and hormonal status in middle-aged and elderly patients with T2DM

Introduction: Acromegaly is usually diagnosed by elevated age- and sex-adjusted insulin-like growth factor-1 (IGF-1) levels reflecting chronic growth hormone (GH) excess. IGF-1 is preferred as a screening biomarker due to its longer half-life and reduced pulsatility compared with GH. However, IGF1 levels may be disproportionately low or only modestly elevated in certain clinical contexts, leading to diagnostic uncertainty. Pituitary apoplexy is one such condition in which acute tumor hemorrhage or infarction may disrupt sustained GH secretion and attenuate IGF-1 production Case: A 48-year-old female with hypertension, type 2 diabetes mellitus, and dyslipidemia presented with a 2-day history of severe headache, vomiting, and visual disturbance, on a background of progressive acral enlargement over 2 years. Examination revealed coarse facial features, prognathism, enlarged hands, and cranial nerve involvement. Magnetic resonance imaging demonstrated an invasive sellar– suprasellar pituitary macroadenoma with optic chiasmal compression and cavernous sinus encasement. Intravenous dexamethasone was initiated pre-operatively due to a significant mass effect. Biochemical evaluation showed markedly elevated random GH levels (>50 ng/mL) with only mildly elevated IGF-1 at 1.19 times the upper limit of normal, below the threshold at which confirmatory oral glucose tolerance testing may be omitted according to current guidelines. Other pituitary axes suggested evolving hypopituitarism. During admission, she developed severe hyperglycemia with marked insulin resistance, requiring high-dose insulin therapy (approximately 1.5 U/kg/day). She underwent urgent transsphenoidal surgery, with histopathology confirming a pituitary neuroendocrine tumor with extensive hemorrhage and infarction, consistent with pituitary apoplexy. Postoperatively, GH levels were suppressed to <5 ng/mL, insulin requirements decreased markedly, and hormone replacement was initiated for secondary adrenal insufficiency and central hypothyroidism. Conclusion This case highlights that IGF-1 levels below conventional diagnostic thresholds do not exclude clinically significant acromegaly, particularly in the setting of pituitary apoplexy. Integration of clinical phenotype, GH levels, and imaging findings is essential to avoid diagnostic delay and ensure timely management.

BACKGROUND

Invasive candidiasis is defined by the growth of Candida species in the bloodstream or other internal organs. It is a global concern due to increasing multidrug resistance and high mortality rates. This study aimed to update prevalence data on Candida infections in the Philippines, analyzing demographic factors (age, sex), specimen sources, and associated risk factors. We compared antifungal resistance patterns against CLSI epidemiological cutoff values (ECVs) and clinical breakpoints and examined MIC variations by underlying disease to inform potential standardized empiric therapies.

METHODOLOGY

We conducted a retrospective analytical cross-sectional study (SLMC-IERC approval, minimal risk) reviewing one year of Candida speciation and susceptibility results from January 2024 to December 2024 at a private tertiary hospital. All aseptically collected samples that tested positive for Candida species were included. Respiratory and wound specimens required a Gram stain demonstrating yeasts and hyphae prior to culture, while urine cultures were included only if they yielded ≥100,000 CFU/mL. Identification and susceptibility testing were performed using the VITEK 2 system, with results interpreted using CLSI breakpoints and ECVs.

RESULTS

Among 266 patients with Candida infections, invasive candidiasis predominated in those aged ≥60 years (66.4%). Candida albicans (21.7%) and Candida tropicalis (13.5%) were more frequent in females, while Candida parapsilosis (13.2%) and Candida glabrata (5.3%) were more common in males. Blood and CSF samples strongly correlated with invasive disease and underlying risk factors. C. albicans was linked to infection-related conditions (13.9%), malignancy (9.0%), and cardiovascular disease (6.8%). C. parapsilosis(23.3%) and C. tropicalis (20.7%) were frequently associated with infection, malignancy, and metabolic disorders. C. glabrata (7.5%), noted for antifungal resistance, was isolated in patients with direct infections (3.4%) and malignancies (1.9%). Among azoles, fluconazole demonstrated greater susceptibility against Candida species, requiring lower concentrations for inhibition, despite a higher resistance rate (13.22%) compared to voriconazole (8.95%). Among echinocandins, micafungin showed better susceptibility than caspofungin. Amphotericin B demonstrated the highest overall susceptibilit y (93 –10 0%), though MICs approached ECV limits. Most susceptible MIC values were fluconazole 0.5 μg/mL for C. albicans and C. parapsilosis, 1.0 μg/mL for C. tropicalis; voriconazole and caspofungin 0.12 μg/mL; micafungin 0.06 μg/mL; amphotericin B 0.5 μg/mL; and flucytosine

CONCLUSION

These findings support a species-specific, risk-adapted approach to antifungal therapy, incorporating demographic and clinical variables. Continuous surveillance of invasive candidiasis prevalence and antifungal MIC trends, with periodic breakpoint updates, is crucial to preserve therapeutic efficacy. Effective management of multidrug-resistant Candidainfections also requires close collaboration between clinicians and pharmacists, as well as the development of new dosing strategies based on pharmacokinetic/pharmacodynamic (PK/PD) principles.

INTRODUCTION

Burn wound infection is a significant risk factor in the morbidity and mortality of burn wound patients. Previous studies in our institution showed bacterial colonization in burn patients seen beyond 24 hours post-injury. The microbiological profile of burn wounds seen within 24 hours, including the presence and risk factors for wound colonization, has not been determined in our Burn Center.

OBJECTIVES

To identify the presence and risk factors for burn wound colonization in burn patients seen less than 24 hours after injury and determine the microbiological profile and antibiotic susceptibility patterns in colonized burn wounds.

METHODS

One hundred eighty-nine burn patients who were seen at and admitted to the UP Philippine General Hospital ATR Burn Center within 24 hours of the burn injury from June 2021 until July 2023 were included in the study. Demographic and clinical data were collected upon admission. A total of 635 swab samples were collected from 189 patients and were sent for identification of aerobic organisms by standard culture methods and antibiotic sensitivity tests using the Kirby-Bauer disc diffusion method. Association of patient characteristics (area of injury, time received post-injury, previous hospital care, place of injury, percent burn injury, etiology, mode of transport, and type of dressing prior to admission) were determined using Chi square test of independence.

RESULTS

Out of 189 burn patients seen within 24 hours after injury included in the study, 58.73% (n = 111) of patients, and 49.29% (n = 313) of swabs showed bacterial colonization. Burn wound colonization was associated with area of injury/body region (χ2 5 = 16.29, p = .0061), time received post-injury (χ2 3 = 24.62, p < 0.0001, post hoc Fisher’s test for 6-12 hours vs. within the first 6 hours: p < 0.0001), place of burn injury (χ2 2 = 18.17, p = 0.0001, post hoc Fisher’s test work vs. home: p = 0.0006, work vs. outdoors: p = 0.0015), percent burn injury (χ2 4 = 21.40, p = 0.0003, post hoc Fisher’s test 25-49% vs. 0-9%: p = 0.004, 50-75% vs. 0-9%: p = 0.002), and etiology of burn injury (χ2 2 = 37.05, p < 0.0001, post hoc Fisher’s test scald vs. flame: p = 0.0012, electrical vs. flame: p < .0001). From 313 positive samples, 357 isolates were identified. Staphylococcus (58.8%) was the most common organism isolated. It was noted that out of the total isolates, 15 (4.2%) were identified to be methicillin-resistant S. aureus (MRSA) while 5 isolates (1.4%) were methicillin-resistant S. epidermidis (MRSE). Streptococcus (10.4%) and Acinetobacter (6.2%) were the second and third most common organisms, respectively. Other groups identified were Aeromonas, Bacillus, Enterobacter, Pseudomonas, Klebsiella, and diphtheroids. Frequency of bacterial isolates differed across body regions, time received post-injury, percent burn injury, and etiology of burn injury. Resistance to one antibiotic was observed in 36.84%, 6.25%, and 63.64% of Staphylococcus, Streptococcus, and Acinetobacter isolates tested, respectively. Resistance to more than 1 antibiotic was observed in 48.68% of Staphylococcus isolates and 50.0% of Streptococcus isolates tested. Among the 51 S. aureus isolates, 29.1% were methicillin-resistant S. aureus (MRSA).

CONCLUSION

In burn patients seen within 24 hours after injury, about half of burn wounds and more than half of patients showed the presence of microbial growth. Potential risk factors for positive microbial growth in a burn wound during this timeframe were area of injury/ body region, place of injury, time received post-injury, percent TBSA burn, and etiology of burn injury. The most common isolate was Staphylococcus spp. More than half of Staphylococcus isolates showed antibiotic resistance, with a significant number showing multidrug resistance. More than a quarter of S. aureus isolates were methicillin-resistant S. aureus (MRSA). These results suggest that bacterial isolates can colonize burn wounds even within 24 hours post-injury and may exhibit antibiotic resistance.

This study aims to investigate the in vitro mechanisms underlying the beneficial effects of puerarin on hepatic insulin resistance(IR) based on the carbohydrate response element-binding protein(ChREBP)/peroxisome proliferator-activated receptor(PPAR)α/PPARγ axis involved in glucose and lipid metabolism. An IR-HepG2 cell model was established by treating cells with dexamethasone for 48 h, and the cells were then treated with 10, 20, and 40 μmol·L~(-1) puerarin for 24 h. Glucose levels and output in the extracellular fluid were measured by the glucose oxidase method, while cell viability was assessed by the cell counting kit-8(CCK-8) assay. The adenosine triphosphate(ATP) content and glycogen synthesis were evaluated through chemiluminescence and periodic acid-Schiff staining, respectively. Western blot was employed to quantify the protein levels of forkhead box protein O1(FoxO1), phosphorylated forkhead box protein O1 [p-FoxO1(Ser256)], glucagon, phosphofructokinase, liver type(PFKL), pyruvate kinase L-R(PKLR), pyruvate dehydrogenase complex 1(PDHA1), insulin receptor substrate 2(IRS2), phosphatidylinositol 3-kinase p85(PI3KR1), phosphorylated protein kinase B [p-Akt(Thr308)], glycogen synthase(GYS), glycogen phosphorylase, liver type(PYGL), adiponectin(ADPN), ChREBP, PPARα, and PPARγ. Additionally, the protein levels of acetyl-CoA carboxylase 1(ACC1), phosphorylated ATP citrate lyase [p-ACLY(Ser455)], sterol regulatory element binding protein 1c(SREBP-1c), peroxisome proliferator-activated receptor gamma coactivator 1α(PGC1α), carnitine palmitoyltransferase 1α(CPT1α), and glucagon receptor(GCGR) were also determined. Immunofluorescence was employed to visualize the expression and nuclear location of ChREBP/PPARα/PPARγ. Furthermore, quantitative PCR with the antagonists GW6471 and GW9662 was employed to assess Pparα, Pparγ, and Chrebp. The findings indicated that puerarin effectively reduced both the glucose level and glucose output in the extracellular fluid of IR-HepG2 cells without obvious effect on the cell viability, and it increased intracellular glycogen and ATP levels. Puerarin down-regulated the protein levels of FoxO1 and glucagon while up-regulating the protein levels of p-FoxO1(Ser256), PFKL, PKLR, PDHA1, IRS2, PI3KR1, p-Akt(Thr308), GYS, PYGL, ADPN, ACC1, SREBP-1c, p-ACLY(Ser455), PGC1α, CPT1α, and GCGR in IR-HepG2 cells. Furthermore, puerarin up-regulated both the mRNA and protein levels of ChREBP, PPARα, and PPARγ and promoted the translocation into the nucleus. GW6471 was observed to down-regulate the expression of Pparα while up-regulating the expression of Chrebp and Pparγ. GW9662 down-regulated the expression of Pparγ while up-regulating the expression of Pparα, with no significant effect on Chrebp. In summary, puerarin activated the hepatic ChREBP/PPARα/PPARγ axis, thereby coordinating the glucose and lipid metabolism, promoting the conversion of glucose to lipids to exert the blood glucose-lowering effect.

The use of antimicrobial agents is an important measure for the treatment of oral and maxillofacial space infection(OMSI). The irrational use of antimicrobials will not only affect the effect of disease treatment, but also leads to the occurrence of bacterial resistance. To standardize the rational use of antimicrobial agents in the treatment of OMSI, this consensus was developed based on the latest evidence-based medical research, incorporating extensive input from pharmaceutical and oral clinical experts, and refined through multiple rounds of discussion and revision. This consensus mainly reviews the anti-infective treatment regimen, common drug use methods, pharmaceutical monitoring, and treatment duration for OMSI. It aims to provide guidance for oral clinicians in the rational use of antimicrobial agents during the treatment of such infections.

Objective To study the impacts of curcumin on the proliferation, migration and cisplatin (DDP) resistance of bladder cancer cells by regulating the liver kinase B1-AMP activated protein kinase-microtubule-associated protein 1 light chain 3 (LKB1-AMPK-LC3) signaling pathway. Methods Human bladder cancer cell line T24 was cultured in vitro, and its DDP resistant T24/DDP cells were induced by cisplatin (DDP). After treating T24 and T24/DDP cells with different concentrations of curcumin, the optimal concentration of curcumin was screened by MTT assay. T24 cells were randomly grouped into control group, curcumin group, metformin group, and combination group of curcumin and metformin. After treatment with curcumin and LKB1-AMPK activator metformin, the proliferation, autophagy, migration, and apoptosis of T24 cells in each group were detected by MTT assay, monodansylcadavrine (MDC) fluorescence staining, cell scratch assay, and flow cytometry, respectively. Western blot was used to detect the expression of proteins related to LKB1-AMPK-LC3 signaling pathway in T24 cells of each group. T24/DDP cells were randomly assigned into control group, curcumin group, metformin group, and combination group of curcumin and metformin. Cells were treated with curcumin and metformin according to grouping and treated with different concentrations of DDP simultaneously. Then, the effect of curcumin on the DDP resistance coefficient of T24/DDP cells was detected by MTT assay. T24/DDP cells were randomly grouped into control group, DDP group, combination groups of DDP and curcumin, DDP and metformin, DDP, curcumin and metformi. After treatment with DDP, curcumin, and metformin, the proliferation, autophagy, migration, apoptosis, drug resistance, and the expression of proteins related to LKB1-AMPK-LC3 signaling pathway in T24/DDP cells of each group were detected with the same methods. Results Compared with the control group, the activity of T24 cells, relative number of autophagosomes, migration rate, Phosphorylated-LKB1 (p-LKB1)/LKB1, Phosphorylated-AMPK (p-AMPK)/AMPK, LC3II/LC3I, and the DDP resistance coefficient of T24/DDP cells in the curcumin group were lower, and the apoptosis rate of T24 cells was higher; the changes in various indicators in the metformin group were opposite to those in the curcumin group. Compared with the curcumin group, the activity of T24 cells, relative number of autophagosomes, migration rate, p-LKB1/LKB1, p-AMPK/AMPK, LC3II/LC3I, and the DDP resistance coefficient of T24/DDP cells in the combination group of curcumin and metformin were higher, and the apoptosis rate of T24 cells was lower. Compared with the control group, there were no obvious changes in various indicators of T24/DDP cells in the DDP group. Compared with the control group and DDP group, the viability of T24/DDP cells, relative number of autophagosomes, migration rate, P-glycoprotein (P-gp) protein expression, p-LKB1/LKB1, p-AMPK/AMPK, and LC3II/LC3I in the combination group of DDP and curcumin were lower, and the apoptosis rate of T24/DDP cells was higher; the changes in the above indicators in the combination group of DDP and metformin were opposite to those in the combination group of DDP and curcumin. Compared with the combination group of DDP and curcumin, the viability of T24/DDP cells, relative number of autophagosomes, migration rate, P-gp protein expression, p-LKB1/LKB1, p-AMPK/AMPK, and LC3II/LC3I in the combination group of DDP, curcumin and metformin were higher, and the apoptosis rate of T24/DDP cells was lower. Conclusion Curcumin can reduce the activity of LKB1-AMPK-LC3 signaling pathway, thereby inhibiting autophagy, proliferation and migration of bladder cancer cells, promoting their apoptosis, and weakening their resistance to DDP.

It has been popular and challenging to undertake researches on the delay of acquired resistance of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKI). As key cells for tumor initiation, cancer stem cells (CSC) play an important role in the process of resistance to EGFR-TKI. Although preliminary studies found that traditional Chinese medicine (TCM) could inhibit CSC properties and delay EGFR-TKI resistance, the specific molecular mechanism remains unclear. By summarizing the empirical syndrome treatment of EGFR-TKI resistance via TCM and combining recent researches on TCM intervention in CSC to delay EGFR-TKI resistance, this review discussed the potential molecular pathways and mechanisms of deceleration in resistance to EGFR-TKI by TCM via inhibiting CSC characteristics, in order to expand the research ideas of TCM in combination with targeted therapy.
