    Effect of cardio-gastric interaction on atrial fibrillation in GERD patients
    (2023) Günlü, Serhat; Araç, Eşref; Aktan, Adem; Kayan, Fethullah; Bernas, Altıntaş; Karahan, Mehmet Zülkif
    Objective: Atrial fibrillation (AF) and gastroesophageal reflux disease (GERD) are very common in daily clinical practice. Post-prandial AF episodes have been reported in GERD patients. Although it was reported in previous studies that it was caused by sympathovagal imbalance, there are no studies on cardiac conduction system involvement. In this study, we aimed to evaluate whether the risk of developing AF increases in untreated GERD patients with non-invasive electrophysiological tests. Methods: The research was prospectively performed. Endoscopy was performed on the individuals due to reflux complaints. ECG was recorded at 25mm/s and 10 mm/mV amplitude, and 24-hour Holter ECG (three-channel; V1, V2, and V5) was performed. ECG parameters were measured and Holter ECG results were analyzed. Results: A total of 120 individuals, 60 patients and 60 controls, were included. No significant statistically differences existed between groups for hypertension, diabetes, smoking, or dyslipidemia (p>0.05). In terms of heart rate, Pmax, Pmin, QTd, and QTcd, there were no significant differences across the two groups (p>0.05). P-wave dispersion (Pd) was substantially higher in the study group (p=0.014). Comparing the heart rate variabilities of 24-hour Holter ECG recordings across the groups, the standard deviation of R-R intervals (SDNN) was substantially higher in the study group (p<0.001). Low Frequency (LF) and LF/HF were significantly higher in the control group (p<0.001 and p=0.003, respectively). AF was detected in nine individuals on Holter ECG. Conclusion: Pd duration and risk of developing AF were higher in GERD patients.

    Examining the effect of COVID-19 vaccines on the menstrual cycle: A study from Turkey
    (LWW, 2023) Toktaş, İzzettin; Akelma, Hakan; Araç, Eşref
    Concerns about a possible relationship between vaccination against Coronavirus Disease 2019 (COVID-19) and menstrual disorders have been raised in the media. In addition, different studies have shown that the COVID-19 vaccine may be associated with menstrual changes. This study was conducted to investigate the effects of COVID-19 vaccines on the menstrual cycle in women. This cross-sectional descriptive study was conducted between August 16 and September 17, 2021. Data were collected through a self-administered questionnaire via an online form sent to the participants through social media. Data of 586 women were included in this study. A total of 82.4% (n = 483) of the participants were aged between 31 and 50 years. The BioNTech vaccine (2 doses) was administered to 75.8% (n = 444), Sinovac (3 doses) to 9.0% (n = 53) of the participants. 53.1% (n = 311) of the women experienced changes in their menstrual cycles. The most common menstrual changes after vaccination were delayed menstruation (n = 176; 30.0%) and prolonged menstrual duration (n = 132; 22.5%). Menstrual delay, prolonged menstrual duration, heavy bleeding, and early menstruation were more common in women than prior to receiving the vaccine (P < .05). More than half of the women experienced menstrual cycle changes after receiving the COVID-19 vaccine. Women experienced significantly higher rates of menstruation delay, prolonged menstrual duration, heavy bleeding, and early bleeding compared to before vaccination.
