Background: Temporal lobe epilepsy (TLE) is a complex neuropsychiatric illness that alters patient's behavior and social well-being. Early and accurate diagnosis of TLE is a key factor in its treatment. Currently, magnetic resonance spectroscopy (MRS) is recommended due to its high sensitivity and specificity in the detection of seizures. However, some studies have reported on its limited role in lesion detection.
Objectives: The present meta-analysis aims to analyze different studies thoroughly and investigate the role of MRS in the detection of TLE.
Material And Methods: A systematic literature review was conducted using Medline (via PubMed), Cinahl (via EBSCO), Scopus, and Web of Sciences databases for case-control, retrospective and prospective studies regarding the use of MRS in detecting TLE. Studies were included using the Population, Intervention, Comparison, Outcomes and Study (PICOS) criteria and relevant event data were extracted. The risk of publication bias was analyzed using the Begg and Mazumdar test. A risk of bias assessment was conducted using RevMan software. The Mantel-Haenszel method was used to calculate the sensitivity, pooled odds ratio (OR), and risk ratio (RR), also using RevMan software.
Results: A total of 16 studies published between 2000 and 2022 were included, which encompassed a total of 645 patients. We obtained a high sensitivity of 84.8%, which shows a high efficiency of MRS, and a pooled OR value of 0.37 (95% confidence interval (95% CI): 0.14-0.97) with a tau2 value of 2.63, χ2 value of 84.99, degrees of freedom (df) value of 15, I2 value of 82%, Z-value of 2.03, and p < 0.05. The pooled RR was 0.82 (95% CI: 0.69-0.97) with a tau2 value of 0.10, χ2 value of 122.11, df of 15, I2 value of 88%, Z-value of 2.25, and p < 0.05. These results were statistically significant for a low risk of publication bias.
Conclusion: The current meta-analysis highly recommends the use of MRS in the accurate detection of alterations seen in the brain in patients with TLE.

Author Affiliation: Assistant Professor, School of Nursing and Healthcare Leadership, University of Washington, Tacoma.
Objective: This study aimed to investigate the mediating role of psychological distress in the relationship between work-family conflict and nurse managers' (NMs') professional and organizational turnover intentions.
Background: Work-family conflict is prevalent among NMs. It can have a significant impact on their intent to leave their organization and the profession.
What has brain diffusion magnetic resonance imaging taught us about chronic primary pain: a narrative review.

Chronic pain is a pervasive and debilitating condition with increasing implications for public health, affecting millions of individuals worldwide. Despite its high prevalence, the underlying neural mechanisms and pathophysiology remain only partly understood. Since its introduction 35 years ago, brain diffusion magnetic resonance imaging (MRI) has emerged as a powerful tool to investigate changes in white matter microstructure and connectivity associated with chronic pain.

Surprisingly innovation process based on deliberate practice has rarely been unearthed that might explore the boundary conditions of the eco-friendly deliberate practice and eco-innovation performance relationship. Anchored on the organizational support theory and the social cognitive, the current study seeks to investigate the impacts of perceived organizational support (POS) and developmental leadership (DL) on eco-innovation performance (EP) through the mediating role of eco-friendly deliberate practice (EDP). In addition, the study explores the boundary effects of employee resilience (ER) on the relationship between EDP and EP.

Saturated sp-carbon nanothreads (CNTh) have garnered significant interest due to their predicted high Young's modulus and thermal conductivity. While the incorporation of heteroatoms into the central ring has been shown to influence the formation of CNTh and yield chemically homogeneous products, the impact of pendant groups on the polymerization process remains underexplored. In this study, we investigate the pressure-induced polymerization of phenol, revealing two phase transitions occurring below 0.

Objectives: Electroconvulsive therapy (ECT) is one of the most effective treatments for treatment-resistant depression (TRD), even though the molecular mechanisms underlying its efficacy remain largely unclear. This study aimed, for the first time, to analyze plasma levels of miRNAs, key regulators of gene expression, in TRD patients undergoing ECT to investigate potential changes during treatment and their associations with symptom improvement.
Methods: The study involved 27 TRD patients who underwent ECT.
