Objective: This study aims to investigate plasma levels of leptin, acyl ghrelin, and unacylated ghrelin during heroin withdrawal in patients with opioid use disorder (OUD) with regard to the relationship of these levels with craving and their changes over time.
Methods: This study included 28 male patients diagnosed with OUD according to DSM-5 diagnostic criteria who received inpatient rehabilitation. The control group included 28 healthy male volunteers with characteristics similar to the patient group. Plasma leptin, acyl ghrelin, and unacylated ghrelin levels of the patients were measured 3 times throughout the study by collecting blood on the first day, the seventh day at the end of the detox, and the twenty-first day. Blood was collected only once from the control group to determine their plasma leptin, acyl ghrelin, and unacylated ghrelin levels.
Results: Our study did not determine any statistically significant differences between patients with OUD and healthy controls with regard to plasma leptin, acyl ghrelin, and unacylated ghrelin levels on the first, seventh, and twenty-first days of withdrawal. Plasma levels of leptin, acyl ghrelin, and unacylated ghrelin did not significantly correlate with craving scores.
Conclusion: This study does not support the hypothesis that plasma leptin, acyl ghrelin, and unacylated ghrelin levels are markers in those with OUD. Further research, particularly in humans, is recommended to replicate and expand on the findings of the current literature.

SERT-Deficient Mice Fed Western Diet Reveal Altered Metabolic and Pro-Inflammatory Responses of the Liver: A Link to Abnormal Behaviors.

Background: The inheritance of the short allele, encoding the serotonin transporter (SERT) in humans, increases susceptibility to neuropsychiatric and metabolic disorders, with aging and female sex further exacerbating these conditions. Both central and peripheral mechanisms of the compromised serotonin (5-HT) system play crucial roles in this context. Previous studies on SERT-deficient (Sert) mice, which model human SERT deficiency, have demonstrated emotional and metabolic disturbances, exacerbated by exposure to a high-fat Western diet (WD).

Article Synopsis
- A study compared appetite regulation among Parkinson's Disease (PD) patients with cognitive impairment (CI), PD patients without CI, and age-matched controls to understand how these factors influence appetite.
- Results showed that PD patients with CI consumed significantly less protein and had altered hormone levels, which were linked to decreased hunger and energy intake.
- The hormones peptide YY (PYY) and glucagon-like peptide 1 (GLP-1) play key roles in appetite control for PD patients, suggesting they are important areas for further research.

Article Synopsis
- The study investigates the lipid and metabolite profiles in Parkinson's disease (PD) patients to uncover new pathways and potential biomarkers for early detection and treatment.* -
- It highlights significant differences in lipid profiles among three groups (No L-Dopa, L-Dopa, and DBS) with findings that show increases in specific lipid species, particularly with deep brain stimulation (DBS) treatment.* -
- The research also reveals dysregulation in amino acid metabolism, especially L-glutamic acid, suggesting that DBS may positively influence glutamate levels, offering insights for future PD diagnosis and therapies.*

Article Synopsis
- * This report highlights how c-Myc activates lipid and serine metabolism, contributing to tumor development, while therapies like aspirin and lomitapide aim to disrupt these metabolic links to inhibit cancer progression.
- * It also discusses various upstream regulators that affect c-Myc in different cancers, along with the potential impact of epigenetic pathways and non-coding RNAs on lipid and serine metabolism, suggesting new avenues for cancer therapies targeting these mechanisms.
Peripheral Biomarkers of Anorexia Nervosa: A Meta-Analysis.

Article Synopsis
- - This study aimed to identify biomarkers related to anorexia nervosa (AN) by analyzing data from various published studies up to mid-2022.
- - It found that certain biomarkers, like acylated ghrelin and cortisol, were significantly higher in individuals with AN, while others, such as leptin and insulin, were lower compared to non-AN controls.
- - The findings suggest that these peripheral biomarkers could be important for understanding the biological mechanisms behind AN and might lead to improved personalized treatments in the future.
