Abstract

Dalam kehidupan sehari-hari tulang lumbar berperan dalam menopang berat badan tubuh dan mendukung gerakan tubuh dalam berkativitas. Tulang lumbar merupakan rangkaian tulang yang sering mengalami keluhan penyakit, salah satu contoh keluhan penyakit yang biasa terjadi adalah low back pain (LBP) atau yang lebih dikenal dengan nyeri punggung bagian bawah tubuh. Kondisi ini bisa terjadi oleh beberapa faktor, antara lain akibat dari melakukan kegiatan fisik secara berlebihan seperti mengangkat beban yang terlalu berat dan dapat diakibatkan oleh kondisi berat badan yang berlebih (obesitas). Simulasi dengan menggunakan metode elemen hingga dilakukan untuk mengetahui pengaruh yang terjadi akibat dari kondisi berat badan yang berlebih terhadap tulang lumbar. Kondisi berat badan dikategorikan dalam 5 kategori indeks massa tubuh (BMI), yaitu underweight, normal, at-risk of obesity, obesitas I, dan obesitas II. Hasil simulasi menunjukkan peningkatan tegangan von Mises seiring dengan kenaikan beban, dengan tegangan tertinggi terjadi pada kategori obesitas II. Temuan ini memberikan wawasan penting terkait risiko penyakit hernia nucleus pulposus (HNP) pada populasi dengan BMI tinggi yang dapat diakibatkan oleh tegangan mekanik pada struktur diskus intervetebralis.

Abstract

Background: Individuals with Down Syndrome are often subjected to social stigma due to their physical appearance. In Indonesia, there was a paucity of research on stigma associated with Down syndrome because the instrument is not available. The study aims to develop and validate the Down Syndrome Stigma Scale in the Indonesian language. Method: An expert panel selected 27 relevant items from the Iranian version of the Stigma Scale towards Down Syndrome. After the translation process, the validity and reliability of the items were evaluated in 79 parents of children with Down syndrome. Results: A factor analysis with factor loading greater than 0.40 was performed. Three factors were identified from 23 items (α=0.928), namely social interaction (10 items; α=0.881), acceptance (8 items; α=0.853), and health-related factors (5 items; α=0.821). Conclusionss The psychometric quality of the Indonesian version of the Down Syndrome Stigma Scale is satisfactory and can be utilized in future research.

Abstract

ABSTRACTBackground: The aging process in the elderly can be caused by a decrease in vitamin D precursors and reduced Vitamin D levels due to impaired absorption of Vitamin D. Vitamin D plays a role in cognitive function, acts as an immunomodulator affecting blood glucose levels, promotes muscle atrophy, and affects the intranuclear VDR concentration and gene expression of VDR.Objectives: To determine the effect of vitamin D3 supplementation on Serum 25(OH)D levels, hand grip strength, blood sugar levels, and cognitive function in the elderly.Materials and Methods: This study used a quasi-experimental pre-posttest control group design with a total of 60 subjects included and divided into two groups. The treatment group received vitamin D3 at a dosage of 1000 IU/day for three months, while the control group was given a placebo. Blood serum levels were used to obtained serum 25(OH)D and blood sugar level. Hand grip strength values were measured by a hand grip dynamometer, and cognitive function was assessed using the Mini-Mental State Examination (MMSE) Questionnaire. The data was analyzed using the Wilcoxon test, and the bivariate analysis was performed using the Mann-Whitney test.Results: Most subjects were between 60 and 92 years old and had a vitamin D deficiency. Significant (P<0,05) differences were observed in serum 25(OH)D levels, blood sugar levels, and cognitive function following the intervention. The differences in serum 25(OH)D levels were 8,50±6,17, blood sugar levels were -21,68±25,88, and cognitive function was 2,23±3,05. Additionally, hand grip strength increased after the intervention (mean=0,42±4,66) but was not statistically significant (P=0,633).Conclusion: There is an improvement in cognitive function and a decrease in blood glucose levels, along with an increase in 25(OH)D levels after three months of vitamin D supplementation. However, hand grip strength did not significantly increase after supplementation.Keywords: Vitamin D3 Supplementation; serum 25(OH)D; hand grip strength; blood sugar level; cognitive function; elderly.

Abstract

Down Syndrome (DS) is a genetic disorder in the form of adding chromosome 21 due to abnormal cell division. This condition causes a distinctive physical appearance and intellectual impairment. The prevalence of DS is between 10-11 out of 10,000 live births worldwide. A 2-week-old baby presented with complaints of jaundice with the clinical picture of DS. There was a mild increase in fT4 levels, and TSH levels were still within the reference value range. Karyotype examination showed Robertsonian translocation of chromosomes 13 and 14 and several abnormalities, namely trisomy 21.

Abstract

BACKGROUND Kidney stones are a global issue with varying prevalence. The most common metabolic risk factor is hypercalciuria, a condition where excess calcium in the urine promotes stone formation. Matrix Gla protein (MGP) inhibits stone formation by preventing crystal growth. This study aimed to analyze the correlation between urinary calcium and MGP levels in kidney stone formation. METHODS A case-control study at Kardinah Hospital, Indonesia, included 64 patients with kidney stone and 64 healthy controls. Exclusion criteria included renal failure, stroke, kidney tumor, heart failure, and hemodialysis. Urinary calcium and MGP were measured using the 5’-nitro-5’-methyl-BAPTA method and enzyme-linked immunosorbent assay. Cut-off values were determined via receiver operating characteristic analysis. RESULTS Among 128 participants (mean age: 51.6), the optimal cut-off for urinary MGP was 1,405 ng/l (p = 0.00024) with 62.5% sensitivity and 72% specificity. Urinary calcium cut-off was 72.5 mg/24 hours with 81.3% sensitivity and 62.5% specificity. Higher urinary calcium and MGP levels were linked to kidney stones (OR: 7.22; 95% CI: 3.23–16.18 and OR: 4.26; 95% CI: 2.03–8.96, respectively). A significant association was found between urinary calcium and MGP (OR: 5.11; 95% CI: 2.31–11.29, p = 0.00006) that hypercalciuria and increased MGP levels are predictors of kidney stone formation. CONCLUSIONS Urinary calcium and MGP levels are associated with kidney stones. Elevated urinary calcium (>1,405 ng/l) increases MGP levels more than 5-fold. Depending on their levels, urinary calcium and MGP act as both promoters and inhibitors of stone formation.

Abstract

Understanding stress distribution on lumbar vertebral endplates is essential for predicting mechanical failure and guiding clinical interventions. Therefore, this study aims to investigate the von Mises stress patterns on the L1/L2 endplates under multiaxial loading using a 3-dimensional finite element (FE) model derived from CT imaging of a healthy 55-year-old male. Anatomical structures were reconstructed in Mimics 21.0, and simulations were conducted in ANSYS Workbench 2023 R2. Material properties for cortical bone, cancellous bone, and intervertebral disc were assigned based on validated biomechanical data. A compressive load of 500 N and multiaxial moments ranging from 2.5 to 10 N•m were applied to simulate physiological movements, while the inferior surface of L2 was fully constrained to reflect realistic boundary conditions. The results showed that the superior endplate experienced the highest von Mises stress, particularly during flexion and lateral bending, indicating increased vulnerability to mechanical overload. Extension loading significantly reduced stress on both endplates, with a 60.54% decrease on the superior endplate and 69.17% on the inferior endplate. Stress distribution was asymmetrical and was influenced by anatomical features, such as cortical thickness and trabecular alignment. These results show the superior endplate as a biomechanically critical region prone to degeneration, emphasizing its importance in implant design, preventive strategies, and risk assessment for microfracture in high-risk populations.

Abstract

Chromosomal aneuploidy is the most common genetic cause of multiple congenital anomalies (MCA), contributing to high neonatal mortality and morbidity rates in intensive care units. Prevalence of live birth double trisomy is rarely reported, with previous studies reporting the involvement of autosomal aneuploidy combined with sex chromosomal aneuploidy that is a more tolerable or benign phenotype. Mostly, a live-born baby with a double trisomy is associated with mosaicism.  This report aims to present a rare case of a viable baby with non-mosaic double autosomal trisomy involving chromosomes 8 and 18. A term baby from advanced maternal and paternal age with low birth weight and height was born from spontaneous vaginal delivery from unremarkable pregnancy. The phenotype was suitable with Edward syndrome with congenital heart anomalies confirmed by cytogenetic analysis with additional extra chromosome 8 (48, XX,+8,+18). The baby was on and off the mechanical ventilator due to respiratory failures, and her health condition gradually deteriorated, leading to her death at the age of 2.5 months due to neonatal pneumonia.
