Background: Reconstruction of mandibular and maxillary defects resulting from malignant tumors has remained a complex challenge in recent years. Defects caused by tumors—as well as trauma, inflammatory diseases, and congenital anomalies—lead to impaired essential functions such as mastication, swallowing, and speech. Prior to the 1950s, reconstruction of maxillofacial hard tissue was not commonly performed. Instead, metal plates were used to reestablish bony continuity, and surrounding tissues were utilized to close soft tissue defects, without effectively restoring function. With modern advances in three-dimensional (3D) virtual planning, it is now possible to accurately plan free bone flaps for reconstructing jaw defects. During surgery, manually bending reconstruction plates to fit donor bone precisely is often not feasible. Preoperative 3D planning allows for precise fabrication of surgical guides and fixation plates, improving accuracy and significantly reducing operative time. Additionally, incorporating dental implant planning into the reconstruction process facilitates restoration of both structural and functional outcomes. Aim: To evaluate the outcomes of mandibular defect reconstruction using scapular free flaps in Mongolia and explore potential approaches to optimize the technique. Materials and Methods: This was a case study series. Data from reconstructive surgeries performed at the National Cancer Center of Mongolia, Central Dental Hospital, and the Mongolia-Japan Hospital were collected. Variables included patient age and sex, etiology of the mandibular defect, size of the scapular bone segment, operative time, ischemia time of the free flap, number of vascular anastomoses performed, and pedicle length. For 3D planning, CT scans of the patient's head and lower limb (slice thickness <1 cm) were used to generate 3D models via the 3D Slicer software. Cutting guides for the mandible and scapula (ASIGA), as well as the reconstruction models (AMS), were printed using a 3D printer. Results: A total of 400 free flap reconstructions were performed during the study period. Of these, 29 cases involved reconstruction of mandibular defects using scapular free flaps. The mean age of patients was 40.0 ± 18.3 years, with 52% (15 patients) being female. The etiologies of the defects included malignant tumors (13 cases, 45%), benign tumors (6 cases, 21%), and pre-existing defects (10 cases, 34%). In one case, tumor resection and mandibular reconstruction were performed using 3D planning. The total operative time was 9 hours and 30 minutes, and the ischemia time was 2 hours and 40 minutes. Conclusion Between 2012 and 2025, a total of 29 mandibular reconstructions using scapular free flaps were performed in Mongolia. Traditional reconstruction methods were associated with prolonged ischemia time. The use of 3D surgical planning has shown potential in significantly reducing ischemia time and improving surgical outcomes.

Background: Type 2 diabetes has increased risk of heart failure 2-4 times more than those in non-diabetic subjects. The early detection of asymptomatic ventricular dysfunction by using NT-pro BNP test in diabetic patients is the best strategy for decreasing morbidity and mortality of heart failure. Aim: The aims of this study were to detect asymptomatic cardiac ventricular dysfunction by using NT-pro BNP test in subjects with type 2 diabetes and to define the factors associated with elevated NT-proBNP. Materials and Methods: This cross-sectional study was included diabetic and non diabetic subjects aged from 35- to 64 years, who had no clinical symptoms of heart failure. Cardiovascular risk factors were detected by clinical examinations. NT-pro BNP determination was performed on an immunoassay analyzer (FIA1100, Getein Bio Medical Inc, China), which uses reagent strip to obtain quantitative NT-pro BNP results in plasma. The cut-off point for NT-pro BNP was 300 pg/ml. Results: A total of 536 subjects without clinical symptoms of heart failure were included in the study of which, 150 were diabetic and 386 were non diabetic. The mean age was 52.8 ± 7.8 years and 281 (52.4%) were females. Cardiac ventricular dysfunction was detected in 7.3% of diabetic and 5.2% of non diabetic subjects. Cardiac ventricular dysfunction in diabetic subjects was increased with age and non-significantly higher in females than in males (8.3% vs 6.4%, p>0.05). In the logistic regression analysis, uncontrolled hypertension (OR 3.80, 95% CI 1.07–13.44), long duration of disease (OR 5.30, 95% CI 1.36-20.66), and ageing (OR 5.40, 95% CI 1.29–22.88) were significantly correlated cardiac ventricular dysfunction in subjects with type 2 diabetes. Conclusion Cardiac ventricular dysfunction in subjects with type 2 diabetes was detected 1.4 times more than those in non diabetic subjects. The likelihood of positive NT-pro BNP test in subjects with type 2 diabetes was independently (p<0.05) associated with advanced age, uncontrolled hypertension and long duration of diabetes.

Background: One of the causes of inflammatory arthritis is excessive production of uric acid or hyperuricemia. It is a painful disease that is treated with a commercial xanthine oxidase inhibitor to decrease uric acid synthesis. However, the treatment is associated with adverse side effects and thus, there is interest in medicinal plants that could have similar therapeutic effects with minimal side effects. There are many reported indigenous plants and trees in the Philippines that are reported to have therapeutic and bioactive compounds. One such plant is Canarium ovatum or locally called pili. This study aimed to determine the antihyperuricemic activity of the ethanolic extract of the leaves of C. ovatum. Objective: Determine the antihyperuricemic activity of the crude ethanolic extract of C. ovatum leaves and its partially purified fractions through inhibition of xanthine oxidase and its effect on the blood uric acid level of oxonate-induced hyperuricemic mice. Methodology: The crude ethanol extract from C. ovatum leaves and its partially purified fractions obtained through column chromatography were tested for their in vitro xanthine oxidase (XO) inhibitory activity by measuring spectrophotometrically the uric acid formation from xanthine as the substrate. The crude ethanol extract and the fraction with the most XO inhibitory activity were then tested for their in vivo XO inhibitory activity in oxonate-induced hyperuricemic mice by measuring their blood uric acid levels using uric acid test strips. Results: The crude ethanolic extract of C. ovatum leaves at 100ppm showed 83.62±2.05% in vitro inhibition of XO while the most active fraction showed 80.30±4.00% inhibition. Both were comparable (p>0.05) to the positive control, allopurinol, which showed 91.47±5.64% inhibition. In vivo, the crude extract and the fraction that showed the highest XO inhibitory activity at 200 mg/kg significantly (p<0.01 and p<0.05) respectively reduced the serum uric acid levels of the hyperuricemic mice one hour after induction as compared to the negative control. Moreover, their antihyperuricemic activity were not statistically significant as compared to that of allopurinol (p<0.0001). Conclusion The crude ethanolic extract of C. ovatum leaves and its most active fraction showed statistically significant in vitro xanthine oxidase inhibition and in vivo antihyperuricemic activity. The activities shown by both crude and active fraction were not statistically different from that determined for allopurinol. Therefore, further studies can be conducted to isolate the most active compound and study its pharmacokinetic properties.

Background: While online orthopedic resources are becoming an increasingly popular avenue for patient education, videos on YouTube are not subject to peer review. The purpose of this cross-sectional study was to evaluate the quality of YouTube videos for patient education in ulnar collateral ligament (UCL) injuries of the elbow. Methods: A search of keywords for UCL injury was conducted through the YouTube search engine. Each video was categorized by source and content. Video quality, reliability, and accuracy were assessed by two independent raters using five metrics: (1) Journal of American Medical Association (JAMA) benchmark criteria (range 0–4) for video reliability; (2) modified DISCERN score (range 1–5) for video reliability; (3) Global Quality Score (GQS; range 1–5) for video quality; (4) ulnar collateral ligament-specific score (UCL-SS; range 0–16), a novel score for comprehensiveness of health information presented; and (5) accuracy score (AS; range 1–3) for accuracy. Results: Video content was comprised predominantly of disease-specific information (52%) and surgical technique (33%). The most common video sources were physician (42%) and commercial (23%). The mean JAMA score, modified DISCERN score, GQS, UCL-SS, and AS were 1.8, 2.4, 1.9, 5.3, and 2.7 respectively. Conclusions Overall, YouTube is not a reliable or high-quality source for patients seeking information regarding UCL injuries, especially with videos uploaded by non-physician sources. The multiplicity of low quality, low reliability, and irrelevant videos can create a cumbersome and even inaccurate learning experience for patients.

To address the increasing need for detecting and validating protein biomarkers in clinical specimens, mass spectrometry (MS)-based targeted proteomic techniques, including the selected reaction monitoring (SRM), parallel reaction monitoring (PRM), and massively parallel data-independent acquisition (DIA), have been developed. For optimal performance, they require the fragment ion spectra of targeted peptides as prior knowledge. In this report, we describe a MS pipe-line and spectral resource to support targeted proteomics studies for human tissue samples. To build the spectral resource, we integrated common open-source MS computational tools to assemble a freely accessible computational workflow based on Docker. We then applied the workflow to gen-erate DPHL, a comprehensive DIA pan-human library, from 1096 data-dependent acquisition (DDA) MS raw files for 16 types of cancer samples. This extensive spectral resource was then applied to a proteomic study of 17 prostate cancer (PCa) patients. Thereafter, PRM validation was applied to a larger study of 57 PCa patients and the differential expression of three proteins in prostate tumor was validated. As a second application, the DPHL spectral resource was applied to a study consisting of plasma samples from 19 diffuse large B cell lymphoma (DLBCL) patients and 18 healthy control subjects. Differentially expressed proteins between DLBCL patients and healthy control subjects were detected by DIA-MS and confirmed by PRM. These data demonstrate that the DPHL supports DIA and PRM MS pipelines for robust protein biomarker discovery. DPHL is freely accessible at https://www.iprox.org/page/project.html?id=IPX0001400000.

INTRODUCTION: Dengue continues to be a major health concern in the Philippines. This study aimed to establish trends and correlations between the incidence of dengue and rainfall, humidity and temperature, respectively, in the different regions. METHODS: Using 2018 records obtained from DOH and PAGASA, correlations were made between monthly measurements of climatic factors and the incidence of dengue using Pearson’s r, while maps and interpolations were generated using quantum geographical information system software. RESULTS: There was a significant positive but weak correlation between the incidence of dengue and rainfall (r = 0.379, 95% CI 0.255, 0.491; p < 0.001) and humidity (r = 0.215, 95% CI 0.080, 0.342; p = 0.002). There was a significant negative but weak correlation between the incidence of dengue and temperature (r = -0.145, 95% CI -0.277, -0.008; p = 0.039). A strong positive correlation was noted between the incidence of dengue, and rainfall and humidity, respectively, in several regions. Multiple regression indicates that rainfall, humidity and temperature are poor predictors of the incidence of dengue (R2 = 0.1436, 0.0461 and 0.0209, respectively). CONCLUSION This study showed overall a significant but weak correlation between an increased incidence of dengue and heavy rainfalls and high relative humidity, and a weak negative correlation for temperature. A high positive correlation of an increased incidence of dengue and heavy rainfalls and high relative humidity was observed in several regions.

With the progress of gene detection technology and the speed-up in new drug development, biological target therapy has fully covered the first-line treatment of advanced NSCLC. Immunotherapy has significantly improved the survival of advanced NSCLC patients with negative driven genes, and the median OS reaches about 2 years (15.6-30 months). EGFR is the most common driven gene. According to different EGFR mutation subtypes (L858R or 19del), different treatment mode (EGFR-TKI single drug, TKI combined with anti-vascular drugs and TKI combined with chemotherapy) is selected as the first-line treatment, which has become a consensus. Depending on the data of median PFS, the treatment efficacy against rare targets is more prominent, which has exceeded the efficacy of standard chemotherap:ALK (alectinib, PFS=34.8 months), ROS1 (ceritinib, PFS=19.3 months), RET (selpercatinib, PFS=18.4 months), BRAF (dabrafenib plus trametinib, PFS=14.6 months), NTRK (larotrectinib, PFS≥12 months) and MET (savolitinib, PFS=9.7 months). In conclusion, the first-line treatment of advanced NSCLC has entered the era of“precision-targeted treatment”based on different molecular typing, and it has become a consensus that high-throughput sequencing is required for newly diagnosed patients.
