Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a common and debilitating side effect of cancer treatment. Nerve growth factor (NGF) plays a crucial role in neuronal health and has been implicated in CIPN development. This study investigated the relationship between serum NGF levels and CIPN in cancer patients undergoing chemotherapy. Methods: A cross-sectional study was conducted on 60 cancer patients receiving chemotherapy at Dr. M. Djamil General Hospital Padang, Indonesia, from June to October 2024. Serum NGF levels were measured, and CIPN was assessed using the Toronto Clinical Scoring System (TCSS). The relationship between NGF and CIPN was analyzed using the Mann-Whitney test. Results: The median serum NGF level was significantly lower in patients with CIPN (n=43) compared to those without CIPN (n=17) (103.26 pg/ml vs. 148.91 pg/ml, p=0.029). No significant association was found between chemotherapy regimens and CIPN or NGF levels. Conclusion: Lower serum NGF levels are associated with CIPN in cancer patients undergoing chemotherapy. NGF may serve as a potential biomarker for CIPN, aiding in early detection and management. Further research is needed to explore the clinical utility of NGF as a predictive and monitoring tool for CIPN.

Background: Emerging evidence suggests a bidirectional relationship between systemic inflammation and both epilepsy and sleep dysfunction. High-sensitivity C-reactive protein (Hs-CRP), a sensitive marker of low-grade systemic inflammation, is elevated in response to pro-inflammatory cytokines. However, the specific link between Hs-CRP levels and subjective sleep quality within the epilepsy population required further investigation. This study aimed to investigate the relationship between serum Hs-CRP levels and sleep quality in patients diagnosed with epilepsy. Methods: A cross-sectional study was conducted involving 40 patients diagnosed with epilepsy attending the neurology clinic at Dr. M. Djamil General Hospital, Padang, Indonesia, between January and February 2025. Patients aged over 17 years diagnosed by a neurologist were included. Serum Hs-CRP levels were quantified using an enzyme-linked immunosorbent assay (ELISA). Sleep quality over the preceding month was assessed using the validated Indonesian version of the Pittsburgh Sleep Quality Index (PSQI). Mann-Whitney U test was employed to analyze the difference in median Hs-CRP levels between patients with good and poor sleep quality. Relationships between baseline characteristics and sleep quality were assessed using Chi-square/Fisher's exact tests for categorical variables and the Mann-Whitney U test for continuous variables. Results: Forty epilepsy patients (median age 25.5 years, range 17-50; 52.5% female) were enrolled. The median duration of epilepsy was 10 years (range 1-35). A majority of patients exhibited uncontrolled seizures (75%) and were receiving AED polytherapy (60%). Based on PSQI scores, 24 patients (60%) were classified as poor sleepers, while 16 (40%) were good sleepers. A significant difference was observed in median serum Hs-CRP levels between the two groups: patients with good sleep quality had significantly lower median Hs-CRP levels compared to those with poor sleep quality (1,271.50 ng/ml [range 58–5,837] vs. 2,771.50 ng/ml [range 509–27,187], p=0.027). Poor sleep quality was significantly associated with younger age (median 23 vs. 36 years, p=0.039) and AED polytherapy (75% vs. 25%, p=0.018). Conclusion: This study demonstrated a significant association between elevated serum Hs-CRP levels and poor subjective sleep quality in patients with epilepsy. Epilepsy patients experiencing poor sleep exhibited significantly higher levels of this inflammatory biomarker. These findings underscore the potential role of systemic inflammation in the complex interplay between epilepsy and sleep disturbances, suggesting Hs-CRP could serve as a potential biomarker linking these conditions.

Background: Type 2 diabetes mellitus (Type 2 DM) is a metabolic disease that causes a global crisis that threatens health and the world economy. Impaired cognitive function is a key factor in reducing health-related quality of life in type 2 DM patients. Phosphorylated Tau (p-Tau) is a microtubule protein that functions in cell signaling, synaptic plasticity, and regulation of genome stability. A malfunction of p-Tau will cause disruption of cell signaling, which can result in impaired cognitive function. This study aims to assess the relationship between serum p-Tau levels and impaired cognitive function in type 2 diabetes mellitus patients. Methods: This research is an observational study, comparative analysis with a cross-sectional design with a sample of 60 type 2 diabetes mellitus patients who sought treatment at the endocrine polyclinic at Dr. M. Djamil General Hospital Padang. Cognitive function was assessed using MoCa-Ina. Serum p-Tau levels were measured using the ELISA method. Data analysis was carried out using SPSS. Results: The average serum p-Tau level in type 2 diabetes mellitus patients with impaired cognitive function was 542.9 pg/ml. The cut-off point for serum p-Tau levels which is associated with impaired cognitive function in type 2 diabetes mellitus patients is 517.2 pg/ml. There was a significant relationship between serum p-Tau levels and impaired cognitive function in type 2 diabetes mellitus patients (p=0.039). Conclusion: There is a significant relationship between serum p-Tau levels and impaired cognitive function in type 2 diabetes mellitus patients.

Background: Traumatic brain injury (TBI) is a global health problem that can cause death and disability in people of productive age. The diagnosis and assessment of TBI severity currently still rely on clinical examination and neuroimaging. However, limited access and cost of neuroimaging are obstacles in many health facilities. Therefore, blood-based biomarkers are needed that can help the diagnosis and prognosis of TBI. Phosphorylated Tau (p-tau) is a potential biomarker that can be measured in serum. This study aims to assess the relationship between serum p-tau levels and severity and outcome in TBI patients. Methods: This research is a comparative study with a cross-sectional design involving 70 TBI patients who came to the emergency room (ER) of Dr. M. Djamil General Hospital Padang. TBI severity was assessed using the Glasgow coma scale (GCS) and grouped into mild (GCS 13-15) and moderate to severe (GCS 3-12). Outcomes were assessed using the Glasgow outcome scale (GOS) and grouped into good (GOS 4-5) and poor (GOS 1-3). Serum p-tau levels were measured using the ELISA method. Data analysis was carried out using SPSS. Results: The median serum p-tau level in the mild TBI group was 165.84 ng/L (IQR 126.18-463.85), while in the moderate to severe TBI group, it was 177.68 ng/L (IQR 87.62-591 .93). There was a significant difference between serum p-tau levels in the mild and moderate to severe TBI groups (p=0.029). The median serum p-tau level in the good outcome group was 167.21 ng/L (IQR 87.62-463.85), while in the poor outcome group it was 187.04 ng/L (IQR 137.75-591.93). There was a significant difference between serum p-tau levels in the good and bad outcome groups (p=0.014). Conclusion: Serum p-tau levels have a significant relationship with severity and outcome in TBI patients. Elevated serum p-tau levels are associated with increased severity of TBI and poor outcomes. Further research is needed to confirm these findings and explore the potential of p-tau as a biomarker in TBI management.
