Article Synopsis
  • The review investigates the unclear relationship between insulin resistance and bone mineral density (BMD), aiming to identify associations using various insulin resistance indices.
  • A systematic review of 27 studies involving over 71,000 participants was conducted, highlighting that indices like HOMA-IR showed no significant link to BMD, while a higher TyG index was generally associated with lower BMD levels.
  • The findings indicate a complex relationship requiring more longitudinal studies for robust conclusions, as the inability to conduct a meta-analysis limits the current results' strength.

After experiencing many ups and downs, chimeric antigen receptor (CAR)-T cell therapy has reached a milestone as an anti-cancer method, as evidenced by the increasing number of clinical trials and approved products. Nonetheless, there is a real need to optimize CAR-T cell therapy and overcome its existing limitations. The importance of cellular starting material for generating CAR-T cells is undeniable, as the current personalized manufacturing approach is the main roadblock to providing a fast, affordable, and standard treatment for patients.

  • This study investigated the relationship between GAP-43 levels in cerebrospinal fluid (CSF) and changes in brain white matter microstructure in Alzheimer's disease (AD) patients.
  • Over a follow-up period of 2 to 4 years, researchers analyzed data from 133 participants and found significant negative correlations between GAP-43 levels and specific diffusion tensor imaging (DTI) measures in early and late mild cognitive impairment (MCI).
  • The findings suggest that GAP-43 and DTI together can serve as new biomarkers to detect and monitor synaptic degeneration in AD, which could help track disease progression and evaluate treatment effectiveness.

Article Synopsis
  • - Various soft markers identified in fetal ultrasounds may indicate potential chromosomal abnormalities, but some can also be normal variations that resolve over time in pregnancy.
  • - A study was conducted to evaluate the effectiveness of these ultrasonic soft markers in diagnosing chromosomal issues like Trisomy 21 and 18, by reviewing 10 relevant studies published before August 2023, which included over 18,500 cases.
  • - Results showed that Trisomy 21 and 18 were the most frequently linked to these soft markers, along with other chromosomal abnormalities, and indicated a higher chance of pathogenic copy number variations in fetuses with multiple soft markers present.

  • The systematic review examined the effects of Nigella sativa (N. sativa) on glycemic index in adults, analyzing data from 30 randomized controlled trials.
  • Results indicated significant reductions in fasting blood sugar (FBS) and hemoglobin A1c (HA1c) levels with N. sativa supplementation, but no impact on insulin levels or HOMA-IR.
  • Further research is needed to establish optimal dosage and duration for effective N. sativa supplementation in improving glycemic markers.

Background: Preclinical research has identified the mechanisms via which bacteria influence cancer treatment outcomes. Clinical studies have demonstrated the potential to modify the microbiome in cancer treatment. Herein, we systematically analyze how gut microorganisms interact with chemotherapy and immune checkpoint inhibitors, specifically focusing on how gut bacteria affect the pharmacokinetics and pharmacodynamics of cancer treatment.

Article Synopsis
  • A study looked at whether moms’ jobs during pregnancy could cause asthma in their kids.
  • Researchers checked 10 previous studies with over 5,000 kids and found no strong link between mom’s work and asthma later on.
  • They concluded that more research is needed, but right now, it seems like mom's occupation during pregnancy doesn’t really affect asthma in children.

Introduction: Keratoacanthoma (KA) and squamous cell carcinoma (SCC) are two cutaneous conditions with morphological resemblance, which can complicate the diagnosis in some cases. Using immunohistochemistry staining of biomarkers could be beneficial in resolving this obstacle.

Objectives: We investigated a variety of biomarkers assessed in different studies in order to find the most important and helpful biomarkers for differentiation between SCC and lesions capable of spontaneous regression.

A review of the kappa opioid receptor system in opioid use.

Neurosci Biobehav Rev

July 2024

Department of Psychiatry, Yale University School of Medicine, 300 George Street, Suite 901, New Haven, CT 06511, USA; Clinical Neuroscience Research Unit, Connecticut Mental Health Center, 34 Park Street, New Haven, CT 06519, USA. Electronic address:

The kappa opioid receptor (KOR) system is implicated in dysphoria and as an "anti-reward system" during withdrawal from opioids. However, no clear consensus has been made in the field, as mixed findings have been reported regarding the relationship between the KOR system and opioid use. This review summarizes the studies to date on the KOR system and opioids.

Insulin-like growth factor-1 (IGF-1) levels in multiple sclerosis patients: A systematic review and meta-analysis.

PLoS One

April 2024

Anesthesia and Critical Care Department, Critical Care Quality Improvement Research Center, Loghman Hakim Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Background And Objective: Multiple sclerosis (MS) is a chronic progressive autoimmune disorder of the central nervous system (CNS) that can cause inflammation, demyelination, and axon degeneration. Insulin-like growth factor-1 (IGF-1) is a single-chain polypeptide mainly synthesized in the liver and brain. IGF-1 causes neuronal and non-neuronal cell proliferation, survival, and differentiation.

Background And Aims: The occurrence of thiamine metabolism dysfunction syndrome (THMD), a rare autosomal recessive condition, may be linked to various mutations found in the and genes. The disease chiefly manifests through ataxia, muscle hypotonia, abrupt or subacute onset encephalopathy, and a decline in developmental milestones achieved during the early stages of infancy. We present findings from an investigation that involved two individuals from Iran, both of whom experienced seizures along with ataxia and hypotonia.

Article Synopsis
  • The systematic review aimed to explore how variations in lipid levels (like HDL, LDL, triglycerides, total cholesterol, and remnant cholesterol) affect the risk of microvascular complications in diabetic patients.
  • The review included seven studies from multiple countries, focused on individuals aged 45-84 with type 2 diabetes, and found that variability in LDL and triglycerides was linked to complications, particularly nephropathy and neuropathy, while HDL showed some protective effects.
  • Despite some findings linking lipid variability to complications, the overall relationship remains unclear and highlights a need for further research across diverse populations to better understand these effects.
