Objective: Digoxin is a cardiac glycoside for treating heart failure and atrial fibrillation. Despite its limited therapeutic range and complex pharmacokinetic properties, this medication continues to be frequently prescribed. This study aimed to evaluate the serum digoxin concentration (SDC) at therapeutic, subtherapeutic, and toxic levels and explore the factors affecting these levels in patients receiving digoxin therapy for heart failure.

Purpose: Cataract, which occurs as a result of lens opacification, is one of the most common causes of vision loss. In the literature, deterioration of the antioxidant system due to the increase in reactive oxygen species and oxidant levels is shown among the causes of cataract formation. The aim of this study was to investigate the antioxidant effect of chrysin on steroid-induced cataract development in an experimental chick embryo model using morphological, histological and biochemical parameters.

Background: The Selvester QRS (S-QRS) score on a 12-lead electrocardiogram (ECG) is associated with both the amount of myocardial scar and poor prognosis in myocardial infarction patients. However, its prognostic value in heart failure (HF) with preserved ejection fraction (HFpEF) is unknown.

Objective: This study aims to investigate the predictive value of the S-QRS score for mortality in HFpEF.

Article Synopsis
  • Additive manufacturing (AM) is a growing industry that raises concerns about potential toxic emissions, particularly ultrafine particles and volatile organic compounds (VOCs), which could impact respiratory health in operators.
  • A study involving 18 AM workers and 20 control participants assessed respiratory effects through questionnaires, blood and urine tests, spirometry, and particle collection from exhaled air.
  • Results showed significant variation in particle and VOC exposure levels based on AM techniques, but respiratory measures were within normal ranges; however, distinct differences in lung surfactant lipid compositions were observed between AM operators and controls.

There is not enough information about tinnitus and related parameters in patients with heart failure with reduced ejection fraction (HFrEF). In our study, we aimed to investigate the frequency of tinnitus in HFrEF patients and the clinical parameters associated with this condition. This study included 100 patients with HFrEF and whose medical treatment was arranged according to their disease stage, and 100 control patients without HFrEF with similar age, gender and cardiovascular risk factors.

Background: There are various distal locking options for the repair of tibia distal diametaphyseal fractures with intramedullary nails. There is no consensus about the superiority of any of these distal locking options. In our study, comparing nails with distal bolt locking screw (DSBLS) and conventional nails; we aimed to compare the clinical and radiological results of intramedullary nail models in fixing tibial distal diametaphyseal fractures.

In this study, we aimed to evaluate the liver stiffness (LS) values and the right ventricle (RV) functions after atrial septal defect (ASD) closure treatment. Sixty-six patients were included (38 female, 28 male) in the study. Patients were grouped into 3 subgroups (group I = 21 patients without ASD closure, group II = 38 patients who underwent ASD closure, and group III = 11 patients with ASD and Eisenmenger syndrome).

Respiratory tract lining fluid (RTLF) is an important component of the lung epithelial barrier. Pathological changes in RTLF may cause increased permeability of the epithelial barrier, but changes within RTLF are difficult to assess non-invasively. The aim of this study was to explore if the use of the non-invasive measurement technique, Particles in Exhaled Air (PEx) and blood test were useful in assessing epithelial barrier, and if cigarette smoking affects the relationship.

Background: Oxidative stress increases in many systemic and endocrine diseases. The effect of increased parathyroid hormone levels (PTH) and the effects of this hormone on oxidative stress in patients with primary hyperparathyroidism (pHPT) is unknown. We aimed to investigate the change of Thiol-disulfide (SH-SS), one of the oxidative stress parameters, in patients diagnosed with pHPT and the usability of this parameter in patients with pHPT.

Background: Although it is known that the left ventricular (LV) ejection fraction (EF) measured by echocardiography is preserved in patients with acromegaly, there is not enough information about the LV and left atrial strain (LV-GLS and LAS).

Objective: This study aimed to evaluate the left ventricular (LV) and left atrial (LA) functions with strain echocardiography (SE) in patients with acromegaly.

Methods: This study included 50 acromegaly patients with active disease and 50 healthy controls with similar age, gender, and body surface area.

Article Synopsis
  • Workers in marble processing plants are exposed to harmful marble dust containing silica, leading to potential genetic and immune system issues.
  • The study assessed the health effects on 48 workers, finding lower levels of protective enzymes and higher DNA damage compared to a control group of 41 individuals.
  • Results suggest that prolonged exposure to marble dust is linked to increased genotoxic and immunotoxic risks among marble industry workers.
