Background: This study aimed to investigate the relationship between myonectin levels and metabolic and hormonal disorders in patients with polycystic ovary syndrome (PCOS).
Methods: One hundred PCOS patients who sought medical advice from September 2017 to March 2019 in our hospital were selected as the PCOS group, while 100 healthy women matched for age and body mass index (BMI) with the PCOS patients were selected as the control group. General clinical information, myonectin levels, and metabolism and sex hormone-related indicators of the two groups were compared, and the correlation between myonectin, metabolism, and sex hormones was analyzed.
Results: There were no significant differences in age, BMI, blood pressure, or other general clinical information between the two groups (P>0.05). Compared with the control group, the levels of myonectin, sex hormone-binding globulin (SHBG), and high-density lipoprotein cholesterol (HDL-C) in the PCOS group were significantly decreased (P<0.05), while the levels of fasting blood glucose (FBG), homeostasis model assessment of insulin resistance (HOMA-IR), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), luteinizing hormone (LH), and testosterone were significantly increased (P<0.05). Pearson correlation analysis showed that the level of myonectin was negatively correlated with BMI, FBG, HOMA-IR, TG, and testosterone but was positively correlated with SHBG and HDL-C. Multivariate linear regression analysis showed that the level of myonectin was negatively correlated with BMI, HOMA-IR, and TG but positively correlated with SHBG and HDL-C.
Conclusions: There is a correlation between the level of myonectin and multiple metabolic and hormone indices in PCOS patients indicating that myonectin may be an effective index to predict metabolic and hormone disorders in PCOS patients.

Background: Severe acute pancreatitis (SAP) is characterized by high mortality rates and various complications, including skeletal muscle atrophy, which significantly exacerbates its outcomes. Despite its clinical relevance, the mechanistic understanding of the relationship between skeletal muscle and the pancreas in SAP remains limited. Our study aimed to elucidate this "organ crosstalk" and its potential implications.

Background/objectives: Recent data indicate the involvement of skeletal muscles in the regulation of metabolism and in the pathogenesis of chronic noncommunicable diseases. The goal of our study was to describe the serum concentrations of myokines in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) and hypertension (HTN) and their correlation with laboratory parameters, blood pressure (BP), and MASLD severity.
Methods: A total of 67 patients with MASLD and HTN underwent anthropometric measurements, laboratory tests, and point shear-wave elastography.

Aim: The purpose of this study was to evaluate irisin, myonectin and high-sensitivity interleukin-6 (hs IL-6) levels in obese children and adolescents and to determine the association of these parameters with metabolic dysfunction-associated steatotic liver disease (MASLD) in children.
Methods: Sixty-one overweight/obese children with suspected liver disease and seventeen healthy controls were included in the study. MASLD was diagnosed according to the latest consensus.

In the context of the global COVID-19 pandemic, understanding the intricate mechanisms of the body's response to infection and inflammation has become a priority for the medical and research communities. It has been proven that during COVID-19 infection, molecules are secreted-namely organokines, which may directly or indirectly play a role in the pathophysiology of COVID-19. The objective of this study was to scrutinize the potential correlation between the levels of selected myokines (myostatin, agrin, irisin, and myonectin) and the duration of rehabilitation in post-COVID-19 patients.
