This study explores the nuanced immunomodulatory effects of sertraline, which is widely used in the treatment of major depression, obsessive-compulsive disorder, and anxiety in adults and children. Recent investigations have emphasized the intricate interplay between depression and the body's inflammatory response. This has sparked an exploration into the impact of sertraline on the immune system, an area that still awaits comprehensive exploration.

This study aims to evaluate the efficacy and outcomes of renal replacement therapy (RRT) in pediatric patients with metabolic diseases, specifically focusing on the impact of hemodialysis (HD) and peritoneal dialysis (PD) on clinical parameters, toxin reduction, and long-term survival. This retrospective study included 10 pediatric patients (eight females and two males) treated at a pediatric nephrology department between 2020 and 2023. Patients diagnosed with metabolic disorders, including maple syrup urine disease (MSUD), methylmalonic acidemia (MMA), and glycogen storage disease (GSD), underwent RRT.

Article Synopsis
  • - The study investigated congenital anomalies of the kidney and urinary tract (CAKUT) in children, focusing on factors leading to the need for ureterorenal surgery by analyzing 651 cases for demographics, genetic mutations, and ultrasound findings.
  • - Findings revealed that a significant proportion of patients had hydronephrosis (46.9%), and surgical intervention was linked to better outcomes in reducing hydronephrosis compared to those who did not undergo surgery.
  • - Risk factors for genetic mutations included low neonatal birth weight, advanced maternal age, and abnormal postnatal ultrasounds, while antenatal hydronephrosis and postnatal urinary tract infections increased the likelihood of requiring surgical intervention.

Background: Cardiovascular autonomic neuropathy (CAN) is a serious complication of diabetes, impacting the autonomic nerves that regulate the heart and blood vessels. Timely recognition and treatment of CAN are crucial in averting the onset of cardiovascular complications. Both clinically apparent autonomic neuropathy and subclinical autonomic neuropathy, particularly CAN pose a significant risk of morbidity and mortality in children with type 1 diabetes mellitus (T1DM).

Adenylate cyclase 3 (ADCY3) gene alterations have been found to be associated with obesity. However, few patients with homozygous mutations have been reported so far, and the follow-up procedure and treatment options have not been clarified. A 10-month-old female presented with increased appetite and weight gain.

Article Synopsis
  • The study focused on identifying (epi)genetic factors in children born small for gestational age (SGA) experiencing undiagnosed syndromic short stature, involving 29 selected cases from a syndromic SGA cohort.
  • Advanced genetic analysis techniques like chromosomal microarray and whole exome sequencing were used, leading to the detection of pathogenic variants and uniparental disomy in several patients.
  • The findings revealed a 55.2% diagnosis rate, introduced 15 rare syndromes linked to SGA, and identified novel genes and copy number variants (CNVs), highlighting the complexity and diversity of syndromic short stature.

The majority of patients with depression are treated with antidepressant drugs that are in the serotonin reuptake inhibitor (SSRI) group. Different studies have been conducted on the effect of treatment with antidepressants on the level of pro-inflammatory cytokines. There have been studies on the effects of escitalopram, an SSRI group antidepressant, on the pro-inflammatory cytokine levels both in vivo and in vitro.

Fluoxetine is an antidepressant drug that is heavily preferred in the cure of depression, which is from the selective serotonin reuptake inhibitor (SSRI) group. There are many reports on the effect of fluoxetine on the immune system, and its effect on the macrophage cells has never been looked at before. We aimed to demonstrate the cytokine production potential of fluoxetine antidepressant, which is widely used in the clinic, in the J774.

Background: Tyrosine kinase inhibitors (TKIs) are the standard of care for resectable and metastatic non-small-cell lung cancer (NSCLC) harbouring epidermal growth factor receptor (EGFR) mutations (EGFRm). We describe the real-world practice of EGFRm testing, prevalence, treatment and outcomes in EGFRm stage III NSCLC from a multi-country, observational study.

Methods: The KINDLE study retrospectively captured diagnostic information, treatments and survival outcomes in patients with stage III NSCLC from January 2013 to December 2017.

Aim: Sarcopenia is a progressive and generalized syndrome that can be linked to many causes such as cancers, and is caused by a quantitative and qualitative disorder (loss of muscle strength and/or physical performance) of skeletal muscle mass. Although sarcopenia has some hypothetical explanation in clinical practice, the mechanisms underlying this condition have not been clearly differentiated in patients with cancer. We aimed to investigate the relationship between irisin, FGF21 and CRP in detecting sarcopenia in colorectal cancer patients.
