    Tas, S; Sarsmaz, K; Sarsmaz, HY; Gürgen, SG; Tas, U; Eyüboglu, M; Ari, Z
    Objective: Gestational hypetension is a major public health concern due to its links with cardiovascular disease, stroke and neonatal morbidity and mortality. Timely diagnosis and effective management of gestational hypertension are essential for both maternal and neonatal health. Neuropeptide FF Receptor 2 (NPFFR2) is a protein secreted by the brain and placenta, involved in pain regulation, water balance, and the modulation of cardiovascular effects. This study aims to conduct a comparative analysis of NPFFR2, smoothelin (SMTH), echocardiographic results and pregnancy outcomes in pregnant women with and without gestational hypertension. Method: This study included 78 pregnant participants, which were grouped into women with gestational hypertension (n = 39) and those without gestational hypetension (n = 39). The gestational hypertension population was classified into two groups, i.e., dipper and non-dipper groups, based on the 24-hour ambulatory blood pressure monitoring results. Smoothelin and NPFFR2 analyses were performed using the blood samples and placental tissue samples collected from all participants, along with echocardiography and 24-hour ambulatory blood pressure monitoring. Results: The study group comprised 78 pregnant women with a mean age of 28.8 years and mean gestational age of 27.7 weeks. The gestational hypertension group had a significantly higher NPFFR2 levels, lower SMTH levels and gestational age at birth and higher all 24-hour ambulatory blood pressure monitoring findings. The left atrial-to-aortic ratio and Tricuspid annular plane systolic excursion (TAPSE) were significantly higher in G & Idot;H group than in the control group. NPFFR2 and gestational age at birth were found to be independently associated with neonatal intensive care unit admission. Conclusion: Serum NPFFR2 levels were increased in women with gestational hypertension, SMTH levels were decreased, and pregnancy prognosis was found to be associated with NPFFR2 levels.

    Time to Reconsidering the Potential Role of Leech Salivary Proteins in Medicine: Type-II Kounis Syndrome Triggered by Leech Bite
    Tas, S; Yildiz, BS; Ersin, A; Tas, U
    Kounis syndrome also known as allergic myocardial infarction, represents the simultaneous occurrence of acute coronary syndromes with allergic or hypersensitivity reactions. We present a case of a 58-years-old male who developed anaphylaxis following a leech bite, leading to myocardial infarction despite the absence of prior allergic history. He was entubated and cardiopulmonary resusciation had been performed for 10 minutes. The patient was successfully resuscitated and Intravenous antihistamine, prednisolone and adrenaline were given. The patient was stabilized and transferred to the intensive care unit and coronary angiography was performed, which revealed a 90% stenosis in the circumflex coronary artery. A stent was successfully implanted in the affected artery. This report emphasizes the complexity of diagnosing and managing Type-II Kounis syndrome and highlights the need for increased clinical awareness.

    Comparison of Serum Spexin Level and its Relationship with Echocardiographic Findings in Prediabetic Patients with and without Hypertension
    Tas, S; Tas, U; Küme, T
    Objective: Prediabetes mellitus, hypertension, and their frequent coexistence are risk factors for macrovascular and cardiovascular complications. In this study we aimed to determine the relationship between spexin levels and echocardiographic findings and hypertension in prediabetic patients. Methods: This study included 118 adult patients diagnosed with prediabetes mellitus who presented to outpatient clinics between April 2021 and January 2022. The patients were grouped into prediabetic patients with hypertension (n = 58) and those without hypertension (n = 60). The hypertension group was further divided into dipper and non-dipper groups according to the 24-hour ambulatory blood pressure monitoring. Blood samples were collected from all patients and echocardiography was performed. Spexin levels were measured by ELISA. Serum spexin levels, echocardiographic and ambulatory blood pressure monitoring findings were compared between the groups. Results: The hypertension and non-dipper groups had significantly lower spexin levels and higher left atrial volume index, E/Em index, and interventricular septum and posterior wall thicknesses. Spexin levels were negatively correlated with body mass index (r = -0.298, P < 0.001), nighttime systolic blood pressure (r = -0.264, P = 0.006), nighttime diastolic blood pressure (r =-.255, P = 0.005), left atrial volume index (r =-.238, P = 0.009), E/Em (r =-.214,P = 0.020), and low-density lipoprotein cholesterol (r = -.243, P = 0.008). Obesity, overweight and spexin <780 pg/mL were independently associated with hypertension. Conclusion: Circulating spexin levels were lower in prediabetic patients with overall hypertension and in non-dipper patients, and were associated with echocardiographic and lipid parameters. The cut-off value of spexin identified in our study may be a useful indicator for hypertension detection and raise clinicians' awareness about evaluating prediabetic patients for hypertension.

    The Relationship between Nocturnal Dipping Status, Morning Blood Pressure Surge, and Hospital Admissions in Patients with Systolic Heart Failure
    Tas, U; Tas, S; Edem, E
    Background: Hypertension is a known risk factor for developing heart failure. However, there is limited data to investigate the association between morning blood pressure surge (MBPS), dipping status, echocardiographic parameters, and hospital admissions in patients with systolic heart failure. Objectives: To evaluate the relationship between morning blood pressure surge, non-dipper blood pressure pattern, echocardiographic parameters, and hospital admissions in patients with systolic heart failure. Methods: We retrospectively analyzed data from 206 consecutive patients with hypertension and a left ventricular ejection fraction below 40%. We divided the patients into two groups according to 24-hour ambulatory blood pressure monitoring (ABPM) results: dippers (n=110) and non-dippers (n=96). Morning blood pressure surge was calculated. Echocardiographic findings and hospital admissions during follow-up were noted. Statistical significance was defined as p < 0.05. Results: The study group comprised 206 patients with a male predominance and mean age of 63.5 +/- 16.1 years. The non-dipper group had significantly more hospital admissions compared to dippers. There was a positive correlation between MBPS and left atrial volume index (r=0.331, p=0.001), the ratio between early mitral inflow velocity and flow propagation velocity (r= 0.326, p=0.001), and the ratio between early mitral inflow velocity and mitral annular early diastolic velocity (E/Em) (r= 0.314, p=0.001). Non-dipper BP, MBPS, and E/Em pattern were found to be independently associated with increased hospital admissions. Conclusion: MBPS is associated with diastolic dysfunction and may be a sensitive predictor of hospital admission in patients with systolic heart failure.

    Tas, U; Tas, S; Kume, T; Yilmaz, O
    Objectives: NPFFR2 is a biomarker produced by the placenta during pregnancy and is thought to be associated with in various physiological processes, including pain modulation, opioid receptor regulation, and cardiovascular function. Pre-eclampsia (PE) is a major public health concern due to its links with cardiovascular disease (CVD), stroke and neonatal morbidity and mortality. Consequently, timely diagnosis and efficient management of PE are essential for both maternal and neonatal health. This study aimed to conduct a comparative analysis of neuropeptide FFR2 (NPFFR2), echocardiographic evaluation results, and pregnancy outcomes in pregnant women with and without PE. Methods: This is a prospective case-control study. It included 94 pregnant participants who applied to Manisa City Hospital between October 2021 to January 2023 and were grouped into women with PE (n = 47) and those without PE (n = 47). Biochemical and NPFFR2 analyses were performed using the blood samples collected from all participants, along with echocardiography and 24 hours. Ambulatory blood pressure monitoring (ABPM). A p-value <0.05 was considered statistically significant Results: The study group comprised 94 pregnant women with a mean age of 29.2 years and mean gestational age of 27.6 weeks. The preeclampsia group had a significantly higher NPFFR2 levels, lower gestational age at birth and higher all 24-hours ABPM findings. The left atrial-to-aortic ratio and right ventricle myocardial performance index were significantly higher and EA ratio was significantly lower in the preeclampsia group than in the control group. NPFFR2, gestational age at birth, LDL cholesterol, and body mass index were found to be independently associated with neonatal intensive care unit admission. Conclusions: The women with PE presented with increased serum NPFFR2 levels and the prognosis of pregnancy was associated with NPFFR2 levels.

    Senel, U; Tanriverdi, HI; Tanriverdi, S; Sapmaz, HI; Akbas, A; Gevrek, F; Uysal, M; Tas, U
    Background: Necrotizing enterocolitis (NEC) is a serious intestinal illness in newborns.Objectives: We aimed to investigate the potential protective effects of hesperidin (Hsd) and diosmin on NEC.Methods: Thirty newborn rats were divided into 3 groups: the control group (n = 10), the NEC group (n = 10), and the treatment group (n = 10). The treatment group was given 100 mg/kg of the flavonoid by oral gavage twice daily. On day 5 of the study, animals were sacrificed under anesthesia. After laparotomy, the tissue samples were obtained from the stomach, cecum, and ileum. NEC scoring was performed histopathologically. Apoptotic changes were evaluated by TUNEL (terminal deoxynucleotidyl transferase-mediated biotin-deoxyuridine triphosphate nick-end labeling) staining. Furthermore, levels of oxidants and antioxidants were determined by biochemical analyzes of the tissues.Results: Glutathione peroxidase (GSH-Px) activity and malondialdehyde (MDA) levels were significantly higher in the NEC group than in the control group in all gastrointestinal tract regions examined. Similar to the control group, GSH-Px and MDA were found to be low only in the cecum in the group treated with flavonoids. NEC damage score and apoptotic index in all 3 regions examined were significantly higher in the NEC group than in the control and treatment groups. The apoptotic index values in the treatment group were similar in the stomach and cecum, and the NEC damage score was similar to those in the control group only in the cecum.Conclusions: Hsd and diosmin treatment significantly reduces the severity of NEC-induced damage and apoptotic cell death, espe-cially in the cecum.
