Risk Factors Associated with Intraocular Pressure and the Correlation of Central Corneal Thickness to Actual Intraocular Pressure in Myopia Patients

2024-08-25T16:07:57+00:00

Background: Myopia, a prevalent refractive error, is associated with an increased risk of glaucoma, a leading cause of irreversible blindness. Central corneal thickness (CCT) is a key factor in glaucoma assessment, as thinner corneas can lead to underestimation of intraocular pressure (IOP). This study aimed to investigate the correlation between CCT and actual IOP in myopic patients, considering various risk factors that may influence IOP.

Methods: This cross-sectional study included myopic patients aged 20-25 years. Participants underwent comprehensive ophthalmic examinations, including visual acuity assessment, autorefraction, CCT measurement using optical coherence tomography (OCT), and Goldmann applanation tonometry for IOP measurement. IOP values were corrected for CCT. Statistical analysis was performed using ANOVA, Pearson correlation tests, and multivariate regression analysis to identify independent risk factors for elevated IOP.

Results: A total of 78 eyes from 78 participants were analyzed. The mean CCT was significantly thinner in moderate myopia compared to mild myopia and emmetropia (p = 0.000). While IOP was lower in moderate myopia, the actual IOP, after CCT correction, was not significantly different among the groups (p = 0.078). A strong positive correlation was found between CCT and IOP (r = 0.737, p = 0.000), and a moderate negative correlation was observed between CCT and actual IOP (r = -0.492, p = 0.000). Multivariate regression analysis identified axial length (p = 0.021) and family history of glaucoma (p = 0.038) as independent risk factors for elevated IOP.

Conclusion: This study highlights the importance of CCT assessment in myopic patients, as thinner corneas can mask elevated IOP. Regular eye examinations, including CCT and IOP measurements, are crucial for early detection and management of glaucoma in this high-risk population. Axial length and family history of glaucoma were identified as independent risk factors for elevated IOP, emphasizing the need for comprehensive risk assessment in myopic individuals.

Prevalence and Analysis of Risk Factors for RAI-Refractory Thyroid Cancer Patients: A 5-Year Retrospective Analysis from a Single Institution in Indonesia

2024-09-04T16:10:29+00:00

Background: Radioactive iodine (RAI) therapy is a cornerstone in the management of differentiated thyroid cancer (DTC). However, a subset of patients develops RAI-refractory disease, characterized by the inability to concentrate radioiodine, leading to limited treatment options and a poorer prognosis. This study aimed to investigate the prevalence and identify potential risk factors associated with RAI-refractory DTC in an Indonesian population.

Methods: A retrospective analysis was conducted on patients diagnosed with DTC and treated with RAI at a single tertiary care center in Indonesia between 2019 and 2023. Data on demographics, clinical characteristics, tumor features, and treatment outcomes were collected. RAI-refractoriness was defined as the absence of iodine uptake on diagnostic whole-body scans after cumulative RAI activity of 600 mCi or more. Bivariate and multivariate analyses were performed to identify risk factors for RAI-refractoriness.

Results: A total of 194 patients with DTC were included in the study. The prevalence of RAI-refractoriness was 90%. The median age at diagnosis was 55 years (range 18-82), and 72% were female. Papillary thyroid carcinoma was the most common histological subtype (92%). In bivariate analysis, older age at diagnosis (p=0.02), male gender (p=0.04), and the presence of distant metastases at diagnosis (p<0.001) were significantly associated with RAI-refractoriness. In multivariate analysis, only the presence of distant metastases remained an independent predictor of RAI-refractoriness (odds ratio 3.8, 95% confidence interval 1.5-9.2, p=0.003).

Conclusion: RAI-refractoriness is a significant clinical challenge in the management of DTC, with a high prevalence observed in this Indonesian cohort. The presence of distant metastases at diagnosis emerged as a strong predictor of RAI-refractoriness. Further research is needed to elucidate the underlying mechanisms of RAI-refractoriness and develop novel therapeutic strategies for this patient population.

Matrix Metalloproteinases as Biomarkers for Ischemic Stroke: A Systematic Review

2024-09-16T16:19:23+00:00

Background: Ischemic stroke, a leading cause of mortality and disability worldwide, occurs due to the disruption of blood flow to the brain, resulting in neuronal damage and death. Matrix metalloproteinases (MMPs), a family of zinc-dependent endopeptidases, play a crucial role in the pathophysiology of ischemic stroke by degrading the extracellular matrix and contributing to blood-brain barrier disruption, inflammation, and neuronal cell death. This systematic review aims to comprehensively evaluate the current evidence regarding the potential of MMPs as biomarkers for ischemic stroke diagnosis, prognosis, and therapeutic monitoring.

Methods: A systematic search of electronic databases (PubMed, Embase, and Cochrane Library) was conducted to identify relevant studies published between 2018 and 2024. Studies investigating the association between MMPs and ischemic stroke in human subjects were included. Data extraction and quality assessment were performed independently by two reviewers.

Results: The search yielded 2,182 articles, of which 8 studies met the inclusion criteria. The included studies evaluated various MMPs, including MMP-2, MMP-3, MMP-9, and MMP-12, in different biological samples (serum, plasma, cerebrospinal fluid, and brain tissue) from ischemic stroke patients. The majority of studies reported elevated levels of MMPs in ischemic stroke patients compared to healthy controls, with MMP-9 being the most extensively studied. Furthermore, several studies demonstrated a correlation between MMP levels and stroke severity, functional outcome, and the risk of hemorrhagic transformation.

Conclusion: The findings of this systematic review suggest that MMPs, particularly MMP-9, hold promise as potential biomarkers for ischemic stroke. However, further research is needed to validate their clinical utility and to explore their potential as therapeutic targets.

The Effects of Carbon Monoxide and Lead Exposure on Lung Function: A Meta-Analysis

2024-09-16T16:18:54+00:00

Background: Carbon monoxide (CO) and lead (Pb) are ubiquitous environmental pollutants with well-established detrimental health effects. The impact of these pollutants on lung function, a critical indicator of respiratory health, has been investigated in numerous studies. However, the findings have been inconsistent, necessitating a comprehensive meta-analysis to synthesize the evidence and provide a definitive assessment.

Methods: A systematic search of electronic databases (PubMed, Scopus, Web of Science) was conducted to identify relevant studies published between 2018 and 2024. Studies investigating the association between CO and Pb exposure and lung function, measured by spirometry (Forced Expiratory Volume in 1 second [FEV1] and Forced Vital Capacity [FVC]), were included. A random-effects model was used to pool the effect estimates, and heterogeneity was assessed using the I² statistic.

Results: The meta-analysis included 25 studies (n = 15,432 participants). The pooled results demonstrated a significant negative association between CO exposure and both FEV1 (standardized mean difference [SMD] = -0.32, 95% confidence interval [CI] = -0.45 to -0.19, p < 0.001) and FVC (SMD = -0.27, 95% CI = -0.38 to -0.16, p < 0.001). Similarly, Pb exposure was associated with a significant reduction in FEV1 (SMD = -0.21, 95% CI = -0.30 to -0.12, p < 0.001). The heterogeneity across studies was moderate to high (I² = 50-75%).

Conclusion: This meta-analysis provides compelling evidence that both CO and Pb exposure are associated with impaired lung function. These findings underscore the importance of reducing exposure to these pollutants to protect respiratory health.

2024-09-17T16:19:24+00:00

Background: Colposcopy is a diagnostic procedure evaluating the cervix following an abnormal screening test. It aims to identify and treat cervical cancer precursors. Risk stratification at the end of colposcopy helps differentiate those who can return to regular screening from those needing more frequent screening or surveillance. The study examined the characteristics and risk factors of patients undergoing colposcopy for cervical dysplasia in Denpasar, Bali, Indonesia.

Methods: This was a cross-sectional study of women who underwent colposcopy at BaliMed Hospital, Denpasar, Bali, Indonesia, from January 2021-December 2022. Data were derived from medical records. The gynecology oncologist performed a colposcopy examination with a biopsy sample, which was later checked by the pathologist. Bivariate and multivariate analyses were used to identify the risk factors associated with cervical dysplasia.

Results: 142 patients underwent colposcopy with a mean age of 37.28+10.1 years. Seventy-eight patients (54.9%) had a low-grade cervical lesion, and 9 (6.3%) had a high-grade cervical lesion. After adjusting the employment status and education level, factors associated with cervical dysplasia were age at first intercourse <20 years (aOR [adjusted odd ratio] 2.44, 95% CI [1.04-5.69]) and history of smoking, either actively or passively (aOR 8.91, 95% CI [3.52-22.54]). From the biopsy result, patients with abnormal cervical lesions were associated with evidence of CIN (aOR 9.03, 95% CI [2.49-32.77]).

Conclusion: Early age first sexual intercourse and history of smoking have been identified as significant risk factors for cervical dysplasia. Additionally, passive smoking has been shown to increase the risk. This research provides a foundational reference for future studies in this area.

Successful Management of Miliary Tuberculosis with Concomitant Anemia: A Case Report

2024-09-17T16:19:09+00:00

Background: Miliary tuberculosis (TB) is a disseminated and potentially fatal form of TB characterized by the hematogenous spread of Mycobacterium tuberculosis, often complicated by anemia of chronic disease. The diagnosis and management of miliary TB, particularly in conjunction with anemia, can be challenging, especially in resource-limited settings.

Case presentation: We report the case of a 20-year-old male from a remote region in Eastern Halmahera, Indonesia, who presented with progressive shortness of breath, productive cough, night sweats, unintentional weight loss, and generalized weakness.

Chest radiography demonstrated diffuse miliary nodules, consolidation, and cavitation, establishing the diagnosis of miliary TB with concomitant anemia. The patient received a standard six-month anti-tuberculosis therapy regimen, along with supportive care and targeted treatment for anemia and associated symptoms. The patient demonstrated significant clinical and hematological improvement, leading to discharge after 11 days of hospitalization. Follow-up assessments confirmed continued progress and the absence of complications.

Conclusion: This case underscores the critical importance of maintaining a high index of suspicion for miliary TB in patients presenting with respiratory and constitutional symptoms, even in the absence of traditional risk factors. The presence of anemia can further complicate the clinical picture. Prompt diagnosis through a combination of clinical assessment, laboratory investigations, and imaging studies, followed by the immediate initiation of appropriate treatment, including the management of anemia, is paramount for achieving favorable outcomes in patients with miliary TB. The case also emphasizes the necessity for comprehensive care and follow-up to ensure sustained recovery and prevent relapse.

Molecular Mechanisms of Ozonized Nigella sativa Oil in Wound Repair: Albumin as Biomarker in Rat Model

2024-09-18T16:20:15+00:00

Background: Wound healing is a complex physiological process that can be impaired in various conditions. Nigella sativa oil, rich in bioactive compounds like thymoquinone, has shown promise in promoting wound healing. Ozone therapy, through the generation of reactive oxygen species (ROS), has also been explored for its potential to accelerate wound repair. This study aimed to investigate the molecular mechanisms underlying the effects of ozonized Nigella sativa oil on wound healing, with a focus on albumin as a biomarker of tissue regeneration in a rat model.

Methods: Full-thickness skin wounds were created on the backs of Sprague Dawley rats. The rats were randomly divided into four groups: a control group receiving no treatment, and three treatment groups receiving topical applications of ozonized Nigella sativa oil at different ozone concentrations (1400 mg/ml, 1800 mg/ml, and 2200 mg/ml) for 7 days. Wound healing was assessed by measuring wound closure rates and histological analysis. Albumin levels in wound tissue were quantified using immunohistochemistry. Additionally, the expression of key genes involved in wound healing, including growth factors, cytokines, and matrix metalloproteinases, was evaluated using quantitative real-time PCR.

Results: Ozonized Nigella sativa oil significantly accelerated wound closure compared to the control group. Histological analysis revealed improved tissue regeneration and collagen deposition in the treated groups. Albumin levels were significantly elevated in the wound tissue of rats treated with ozonized Nigella sativa oil, particularly at the highest ozone concentration. Furthermore, the expression of growth factors (VEGF, TGF-β), pro-inflammatory cytokines (IL-1β, TNF-α), and matrix metalloproteinases (MMP-2, MMP-9) was modulated in a manner consistent with enhanced wound healing.

Conclusion: Ozonized Nigella sativa oil promotes wound healing in a rat model through multiple molecular mechanisms, including the stimulation of albumin synthesis, growth factor expression, and controlled inflammation. These findings suggest that ozonized Nigella sativa oil may have therapeutic potential for enhancing wound repair in clinical settings.

The Impact of Infection Prevention Bundles on Neurosurgical Outcomes and Healthcare Costs: A Systematic Review

2024-09-19T16:20:19+00:00

Background: Post-operative infections represent a significant challenge in neurosurgery, leading to increased morbidity, mortality, and healthcare costs. The implementation of infection prevention bundles, which encompass a set of evidence-based practices, has emerged as a potential solution to mitigate these adverse outcomes. This systematic review aims to evaluate the effectiveness of infection prevention bundles in improving neurosurgical outcomes and reducing healthcare costs.

Methods: A comprehensive search of electronic databases (PubMed, Scopus, Web of Science) was conducted to identify studies published between 2010 and 2023 that evaluated the impact of infection prevention bundles on neurosurgical outcomes and healthcare costs. The search strategy included keywords such as "neurosurgery," "infection prevention," "surgical site infection," "bundle," "outcomes," and "healthcare costs." Studies were included if they reported on at least one clinical outcome (e.g., surgical site infection rates, mortality, length of stay) and/or healthcare costs. Data extraction and quality assessment were performed independently by two reviewers.

Results: The search yielded 45 studies that met the inclusion criteria. The studies encompassed a variety of neurosurgical procedures, including craniotomies, spinal surgeries, and deep brain stimulation. The infection prevention bundles implemented varied across studies but commonly included preoperative antibiotic prophylaxis, skin antisepsis, and intraoperative measures. The pooled analysis demonstrated a significant reduction in surgical site infection rates and length of stay associated with the use of infection prevention bundles. Moreover, several studies reported cost savings, primarily attributed to reduced complications and shorter hospital stays.

Conclusion: The evidence suggests that infection prevention bundles are effective in improving neurosurgical outcomes and reducing healthcare costs. The implementation of these bundles should be considered a standard of care in neurosurgery to enhance patient safety and optimize resource utilization. Keywords: Neurosurgery, infection prevention, surgical site infection, healthcare costs, systematic review.
