Summary: This study found that both acylated and total ghrelin levels were significantly reduced in bipolar disorder patients compared to healthy controls, and were positively correlated with markers of illness severity but negatively correlated with prescribed mood stabilizers, weight, and body mass index.

Summary: This study found that patients with congenital generalized lipodystrophy (CGL) have appetite disturbances compared to eutrophic individuals, with lower fasting acylated ghrelin levels and no physiological drop after meal intake. These disturbances seem to play a role in hunger attenuation and satiety, but not in acute satiation.

Summary: This study found no correlation between circulating NAA levels, central NAA levels, cognitive function, or cerebral small vessel disease. These results indicate that circulating NAA levels do not reflect the related features in the brain.

Summary: This study investigated potential plasma biomarkers associated with the pathophysiologic progression of coronary chronic total occlusion (CTO) and identified protein dynamics in plasma after successful revascularization of CTO vessels. The results revealed that proteins were mainly related to negative regulation of proteolysis, regulation of peptidase activity, negative regulation of hydrolase activity, humoral immune response, and lipid location.

Summary: This meta-analysis found that obese individuals have lower baseline levels of circulating acyl ghrelin (AG) and des-acyl ghrelin (DAG), as well as a faster decline in postprandial AG levels. These findings provide important clinical evidence for further investigations into the role of various forms of ghrelin in energy homeostasis.

Summary: This study investigates the influence of glucose, insulin, body fat, BMI, food intake, and physical activity on serum sOb-R levels. The researchers found that BMI and insulin were causally linked to decreased sOb-R levels, while intensive exercise and food intake acutely increased sOb-R levels.

Summary: This study aimed to investigate the effects of exercise and meal consumption on the concentration of butyrylcholinesterase (BChE) and acylated ghrelin in young healthy men. The findings suggest that BChE may not be involved in suppressing acylated ghrelin after exercise and meal consumption.

Summary: This study aimed to determine serum total and acylated ghrelin levels serially in critically ill patients and investigate their relationship with clinical outcomes in the intensive care unit. The findings showed that ghrelin levels slightly decreased while acylated ghrelin levels substantially increased over time in critically ill patients. There was no significant difference between serum total ghrelin/acylated ghrelin levels and ICU mortality.

Summary: Moderate caloric restriction can improve insulin sensitivity in obese individuals, potentially due to increased levels of unacylated ghrelin (UnAG). The study found that caloric restriction led to an increase in UnAG levels and was positively associated with improvements in insulin sensitivity.

Summary: This study investigates the role of multisensory information in memory-guided spatial navigation. The results show that the availability of multisensory input improves spatial navigation in both individuals with hippocampal lesions and those without. It has a significant impact on navigational behavior, with greater improvement in spatial memory performance observed in patients. The study concludes that congruent multisensory information shifts computations to extrahippocampal areas that support spatial navigation and compensates for spatial navigation deficits.

Summary: This study found that hyperinsulinemia increases bronchoconstriction induced by the vagus nerve in obese rats, as well as significantly increases methacholine-induced airway smooth muscle contraction. Insulin enhances intracellular calcium and smooth muscle contraction, providing insights into potential asthma treatment targets.

Summary: Increased maternal food intake affects fetal development and metabolism, with gut-hormone molecules playing a crucial role. However, the correlation between maternal appetite axis hormones and birth weight is not consistent, suggesting their role in regulating fetal energy deposition mechanisms.

Summary: Resveratrol, a polyphenol chemical found in many plant-based dietary products, has potential health benefits. After ingestion, it undergoes extensive metabolism, inhibits adipogenesis and fat accumulation, possesses anti-inflammatory effects, and may improve insulin sensitivity and inflammatory status. However, optimal dosage and benefits within the general population need further research.

Summary: This study aimed to assess the long-term effects of a dietary intervention high in protein and unsaturated fatty acids on intrahepatic lipids and metabolism. The study found that in adherent older individuals following dietary recommendations, a high-protein and unsaturated fatty acids diet can have beneficial long-term effects on liver fat and lipid metabolism.

Summary: The objective of this study was to examine the effects of lifestyle intervention on impaired insulin secretion in specific subphenotypes of prediabetes. Participants from the Prediabetes Lifestyle Intervention Study were divided into six prediabetes clusters and assessed for insulin secretion, glycemia, insulin sensitivity, and liver fat changes during a 1-year intervention. The lifestyle intervention improved glycemic traits in all high-risk clusters, while insulin secretion increased only in clusters 3 and 5. However, high liver fat in cluster 5 hindered the improvement of insulin secretion.

Summary: This study investigates the contribution of amino acids to postprandial hyper-glucagonemia in type 2 diabetes patients. The research shows that type 2 diabetes patients have excessive glucagon responses after mixed meals, while the obese control group only shows small initial and delayed greater glucagon responses. The role of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) in mixed meals is unclear.

Summary: This study examined the response of subcutaneous adipose tissue (SAT) to exercise and compared it with skeletal muscle. The results showed that SAT responds differently to exercise, with reductions in transcripts related to lipid storage and lipogenesis, as well as modulation of the circadian rhythm, which can potentially prevent metabolic syndrome progression towards diabetes.

Summary: Pancreatic metastases (PMs) from neuroendocrine neoplasms (NENs) are rare but can be detected using new diagnostic tools. A retrospective analysis was performed to study the characteristics and prognostic significance of PMs in NEN patients. The presence of PMs did not have a significant negative impact on overall survival (OS) in this study.

Summary: This study investigated the gene expression changes in white adipose tissue after an isocaloric high-fat diet in healthy human twins. The results showed that fatty acid transport was reduced, while fructose transport was increased, potentially leading to increased de novo lipogenesis. These gene expression changes were partially inherited.

Summary: The Mediterranean Diet is a plant-based diet rich in vegetables, fruit, cereals, and olive oil. It has numerous health benefits, including improved longevity, reduced risk of chronic diseases such as diabetes and obesity, and improved cognitive function. The diet also influences the gut microbiota, promoting the growth of beneficial bacteria and reducing the growth of harmful bacteria. The adoption of the Mediterranean Diet is beneficial for both health and the environment, and should be encouraged globally.

Summary: Metabolic-associated fatty liver disease (MAFLD) has become the most common cause of chronic liver disease globally, affecting one in four people. Despite only a small proportion of MAFLD patients progressing to cirrhosis, it still plays a significant role in its development. However, MAFLD faces challenges such as insidious and asymptomatic onset, lack of accurate diagnostic tests, and absence of specific therapies.

Summary: Nonalcoholic fatty liver disease (NAFLD) is strongly associated with metabolic syndrome and type 2 diabetes, and can independently lead to long-term complications. Direct diagnostics for NAFLD are either invasive, costly, or dependent on the examiner's expertise. Biomarkers, specifically liver fat indices, provide a cheap diagnostic alternative for NAFLD prediction, but have limited accuracy for liver fat quantification. Currently, they lack precision for individual patient monitoring but can serve as compound biomarkers in large cohorts.
