Article Synopsis
  • CLOCK is a transcription factor that influences biological rhythms and has been linked to various factors such as sleep patterns and obesity, but research on its effect on adolescents' dietary habits is limited.
  • A study involving 300 adolescents explored the relationship between specific CLOCK gene polymorphisms (rs3749474, rs4580704, and rs1801260) and their impacts on weight, dietary energy intake, and meal frequency.
  • Results showed that certain gene variants were associated with increased risks of obesity, higher energy intake, snacking habits, and a correlation between breakfast frequency and BMI, indicating the potential influence of genetics on adolescent dietary behaviors and metabolism.

Increasing the awareness of adolescents about hedonic hunger, understanding the difference between homeostatic hunger and hedonic hunger, and adolescents learning to control themselves to stop excessive food consumption are extremely important for a healthy adulthood. The study aimed to evaluate the effects of the multi-strategy nutrition education programs (MSNEP) on hedonic hunger, food addiction, nutrition literacy, and nutritional status in adolescents. This study was planned using a pre-test and post-test design.

Purpose Of Review: Adequate and balanced nutrition during pregnancy is essential for both the mother's and fetus's health. The increased dietary intake of ultra-processed foods (UPFs) and their significant share in the diet negatively affects diet quality and gestational weight gain during pregnancy. The aim of this systematic review was to examine the association of UPFs consumption with diet quality and gestational weight change among healthy pregnant women, using data from observational studies (PROSPERO Identifier: CRD42023468269) from the last 10 years.

Unlabelled: Background: Obesity, which results from a long-term positive energy balance, is affected by many factors, especially nutrition. The sensory properties of foods are associated with increased food intake through hedonic appetite. Taste perception, a component of flavor, is also responsible for increased consumption, through reward and hedonic mechanisms.

The developing fetus is dependent on the maternal nutritional environment. This study was conducted to determine the effects of a maternal high-fat diet (HFD) applied during pregnancy and/or lactation on the expression levels of some lipid-related genes in rat models. Half of the pregnant rats (n: 6) were fed an HFD (energy from fat: 45%), while the other half (n: 6) were fed a control diet (CD) (energy from fat, 7.

Background: Chronic obstructive pulmonary disease (COPD) is a common chronic inflammatory lung disease with high mortality and morbidity rates. Obesity, various comorbid diseases, and inflammation often coexist in chronic obstructive pulmonary disease (COPD), exhibiting a complex interaction with disease severity. The aim of the study was to examine the relationship between COPD markers and obesity, the Charlson Comorbidity Index (CCI), and neutrophil/lymphocyte ratio (NLR).

The gut microbiota, which plays an important role in health and disease processes, is affected by many disease processes, such as cirrhosis, and dysbiosis can lead to the development of numerous liver diseases, including complications of cirrhosis. In this disease group, the intestinal microbiota shifts towards dysbiosis for reasons such as endotoxemia, increased intestinal permeability, and decreased bile acid production. Although weak absorbable antibiotics and lactulose are among the treatment strategies in cirrhosis and its most common complication, hepatic encephalopathy (HE), this may not be the most appropriate treatment option for all patients, in view of its side-effects and high costs.

This study was conducted to describe the dietary patterns and diet quality and to examine the correlation between diet quality, dietary patterns (Mediterranean or DASH) and migraine attributes. Individuals between the ages of 18-64 who applied to the headache outpatient clinic and were diagnosed with episodic migraine were evaluated by a neurologist. Healthy Eating Index-2010 was used to determine the diet quality.

Fetuin-A (Alfa 2-Heremans-Schmid) is a glycoprotein that is mainly synthesized by hepatocytes and then released into the bloodstream. While fetuin-A, a multifunctional protein, has inhibitory effects on health in the processes of calcification, mineralization, coronary artery calcification (CAC), and kidney stone formation by various mechanisms, it has such stimulatory effects as obesity, diabetes, and tumor progression processes. Fetuin-A produces these effects on the organism mainly by playing a role in the secretion levels of some inflammatory cytokines and exosomes, preventing unwanted calcification, inhibiting the autophosphorylation of tyrosine kinase, suppressing the release of adiponectin and peroxisome proliferator-activated receptor-γ (PPARγ), activating the toll-like receptor 4 (TLR-4), triggering the phosphatidylinositol 3 (PI3) kinase/Akt signaling pathway and cell proliferation, and mimicking the transforming growth factor-beta (TGF-β) receptor.

Parkinson's disease (PD) is a neurodegenerative disease characterized by motor impairment and the accumulation of alpha-synucleinopathy (α-syn), which can affect different levels of the brain-gut axis. There is a two-way communication between the gastrointestinal tract, and brain that includes the gut microbiota. This bidirectional communication between the gut microbiota and the brain includes many pathways, such as immune mechanisms, the vagus nerve, and microbial neurometabolite production.

Fetuin-A is a glycoprotein structured molecule which is mostly released by the liver. As a multifunctional protein, fetuin-A has positive effects on health such as calcification, cardiovascular diseases and tumor development processes with various mechanisms, whereas it plays a negative role in the processes of obesity, diabetes and fatty liver disease. There are a large number of studies reporting that serum fetuin-A levels are affected by several dietary factors.

Hemodialysis patients may be at risk for malnutrition due to catabolic effects caused by dialysis, loss of amino acids, inadequate nutrient intake, acidosis, and inflammation. Malnutrition may have negative effects on quality of life, mortality, and disease prognosis. This study was conducted to determine the relationship between anthropometric parameters, depression, and quality of life with Malnutrition Inflammation Score (MIS) on 55 patients aged between 18 and 65 years (36 males and 19 females) who have dialysis treatment for 3 days per week for at least 3 months due to end-stage renal disease.
