Non-O Blood Group Is Associated with High Thrombus Burden and Poor Short- and Long-Term Prognosis in ST-Segment Elevation Myocardial Infarction Patients.

INTRODUCTION: This study investigated how non-O blood groups relate to thrombus burden (TB) and prognosis in ST-segment elevation myocardial infarction (STEMI) patients, aiming to shed light on their association with thrombotic complications in cardiovascular diseases. METHODS: Retrospectively, 1,180 STEMI patients undergoing primary percutaneous coronary intervention were included. The study population was divided into groups according to TB status and the groups were compared in terms of basic clinical characteristics, laboratory parameters and ABO blood group types. In addition, short-term (30 days) and long-term (12 months) clinical outcomes were assessed to evaluate the prognostic implications. RESULTS: The analysis revealed a significant association between non-O blood groups and increased TB in STEMI patients (p = 0.001). Non-O blood group was independently associated with high TB (OR: 1.726, 95% confidence interval [CI]: 1.279-2.330, p < 0.001). Additionally, patients with non-O blood groups had higher short and long-term mortality rates (hazard ratio [HR]: 2.480, 95% CI: 1.361-4.520, p = 0.003; HR: 2.347, 95% CI: 1.433-3.844, p = 0.001; respectively). CONCLUSIONS: This study emphasizes the significance of the ABO blood group system in STEMI outcomes, associating non-O blood groups with higher TB and poorer clinical outcomes. While proposing personalized treatment strategies based on blood group status to improve reperfusion interventions and outcomes, additional trials are needed to comprehensively evaluate their impact.

The predictive value of the HALP score for no-reflow phenomenon and short-term mortality in patients with ST-elevation myocardial infarction.

OBJECTIVE: ST-elevation myocardial infarction (STEMI) is a medical emergency demanding immediate intervention, and primary percutaneous coronary intervention (pPCI) is the standard of care for this condition. While PCI has proven highly effective, a subset of patients experience the devastating no-reflow phenomenon, and some face increased short-term mortality. The Hemoglobin, Albumin, Lymphocyte, and Platelet (HALP) score, a novel biomarker-based tool, has recently surfaced as an innovative predictor of these adverse outcomes. This study aims to investigate the groundbreaking findings that designate a low HALP score as a robust risk factor for no-reflow and short-term mortality in STEMI patients. METHODS: 1817 consecutive STEMI patients who underwent pPCI were included in this retrospective study, and the patients were divided into two groups according to whether no-reflow developed or not, and the HALP scores of the groups were compared. In addition, short-term mortality was compared between the study groups according to their HALP score values. The predictive ability of the HALP score for no-reflow was evaluated using a receiver operating characteristic curve. RESULTS: No-reflow developed in 198 (10.1%) of the patients included in the study. HALP score value was found to be significantly lower in the no-reflow group (27 ± 13 vs 47 ± 24, p < 0.001). After multivariable adjustment, the HALP score was an independent predictor of no-reflow (OR, 0.923, 95% CI, 0.910-0.935, p < 0.001). Furthermore, the HALP score showed good discrimination for no-reflow (AUC, 0.771, 95% CI, 0.737-0.805, p < 0.001). In addition, HALP score was determined to be an independent predictor for short-term mortality (HR, 0.955, 95% CI, 0.945-0.966, p < 0.001). CONCLUSIONS: HALP score can independently predict the development of no-reflow and short-term mortality in STEMI patients undergoing pPCI.

Comparative Evaluation of Intermountain Risk Score With Mehran Risk Score for Risk Estimation of Contrast-Induced Nephropathy and Short-Term Mortality in ST-Segment Elevation Myocardial Infarction Patients.

Contrast-induced nephropathy (CIN) has become one of the most important causes of in-hospital acute renal failure with the increasing use of contrast-mediated imaging tools. This significantly increases the morbidity and mortality of the affected subjects and causes a financial burden on the health system. In this context, prediction of CIN is important and some risk scores have been developed to predict CIN. The most frequently used and popular among these is the Mehran Score (MS), which is based on a number of hemodynamic and metabolic parameters. The Intermountain Risk Score (IMRS) is a recently developed risk score that highly predicts short-term mortality based on common laboratory parameters, and many parameters of this risk score have been found to be closely associated with CIN. In this context, we aimed to compare MS and IMRS in terms of CIN and short-term mortality estimation. The study included 931 patients who underwent percutaneous coronary intervention. CIN developed in 21.5% of patients. Both MS and IMRS independently predicted CIN. In receiver operating characteristic analysis, IMRS was found to be non-inferior to MS in predicting CIN and IMRS was superior to MS in predicting short-term mortality. IMRS and MS were independently associated with short-term mortality.

The HbA1c/C-Peptide Ratio is Associated With the No-Reflow Phenomenon in Patients With ST-Elevation Myocardial Infarction.

Currently, the gold standard treatment for ST-elevation myocardial infarction (STEMI) is primary percutaneous coronary intervention (pPCI), but even after successful pPCI, a perfusion disorder in the epicardial coronary arteries, termed no-reflow phenomenon (NR), can develop, resulting in short- and long-term adverse events. The present study assessed the relationship between NR and HbA1c/C-peptide ratio (HCR) in 1834 consecutive patients who underwent pPCI due to STEMI. Participants were divided into two groups according to NR status and the demographic, clinical and periprocedural characteristics of the groups were compared. NR developed in 352 (19.1%) of the patients in the study. While C-peptide levels were significantly lower in the NR group, HbA1c and HCR were significantly higher (P < .001, for all). In multivariable analysis, C-peptide, HbA1c, and HCR, were determined as independent predictors for NR (P < .05, for all). In Receiver Operating Characteristic (ROC) analysis, HCR predicted the NR with 80% specificity and 77% sensitivity. In STEMI patients, combining HbA1c and C-peptide in a single fraction has a predictive value for NR independent of diabetes. This ratio may contribute to risk stratification of STEMI patients.

Investigation of Helicobacter pylori antigen in stool samples of patients with upper gastrointestinal complaints.

Helicobacter pylori infection is usually acquired in early childhood and it can persist throughout life without antibiotic treatment. This study aimed to compare the accuracy of the noninvasive H. pylori Stool Antigen Test-applied on the stool samples with the invasive gold standart Rapid Urease Test-applied on the gastric biopy samples of patients with upper gastrointestinal complaints. After endoscopy, biopsy and stool specimens were taken in 122 patients. The infection was detected with rapid urease test which is accepted as gold standart test. Rapid, one-step H. pylori card test was applied to all patients stool specimens. In this study 106 of the 122 patients (86.8%) were positive for H. pylori infection, while 16 of the 122 patients (13.2%) were negative. H. pylori card test was negative in 13 of the 16 patients and was positive in 98 of the 106. The sensitivity, specifity, positive and negative predictive values were 92.45%, 81.25%, 97.02%, and 61.90%, respectively. H. pylori card test is rapid, easy, noninvasive and inexpensive methods for detection H. pylori infection. This test showed high sensitivity and specificity. Additionally, it may be a good alternative to invasive tests for the detection of H. pylori infections especially in children.

Submandibular and intracranial hydatid cyst in an adolescent.

OBJECTIVES: An unusual case of hydatid disease is reported. Review of the pertinent literature did not reveal any hydatid disease located simultaneously in both the intracranial and submandibular glands. This is the first case with hydatid disease occurring in both locations at the same time. STUDY DESIGN: The case of an 18-year-old is presented; the symptoms, findings, methods of diagnosis, and our approach for treatment are discussed; and the literature is reviewed. RESULTS: The intracranial lesion was completely excised by left-sided frontoparietal craniotomy, and the mass in the right side of the submandibular gland was removed through a submandibular approach at the same session. The intact cyst was completely excised. Histological examination of both lesions confirmed the diagnosis of hydatid cyst by. Postoperative recovery was uneventful, and the patient was discharged on the seventh day. CONCLUSIONS: Hydatid cyst should be suspected during the evaluation of cervical masses, particularly in endemic regions. Hydatid disease infestations are best treated with complete excision of the intact cyst.

The effects of folic acid in the prevention of neural tube development defects caused by phenytoin in early chick embryos.

STUDY DESIGN: The effects of phenytoin and folic acid on the development of neural tube defects in early chick embryos were studies. OBJECTIVE: To investigate the effects of folic acid in the prevention of neural tube development defects. SUMMARY OF BACKGROUND DATA: Several studies have shown that phenytoin selectively inhibits neural tube closure. Folic acid supplementation has been reported to decrease the occurrence of neural tube defects. METHODS: This study shows the effects of folic acid in preventing neural tube development defects caused by phenytoin in chicks based on light microscopy, transmission electron microscopy, and histopathological examination. Forty-five fertile Hubbard Broil eggs, all at Stage 8 (four somite) of development, were divided into three equal groups: Group 1 embryos (n = 15), the control group, were explanted and grown for 18 hours in a nutrient medium (thin albumin). Group 2 embryos (n = 15) were explanted and grown for 18 hours in a nutrient medium containing 500 microg/mL of phenytoin. Group 3 embryos (n = 15) were explanted and grown for 18 hours in a nutrient medium containing 500 microg/mL of phenytoin and 0.4 microg/mL of folic acid. RESULTS: After the incubation period, 86.6% of the control embryos (Group 1) had intact neural tubes; 80% of Group 2 and 46.6% of Group 3 embryos showed neural tube defects. CONCLUSIONS: The results of this study suggest that phenytoin causes neural tube defects, whereas folic acid decreases the incidence of neural tube development defects caused by phenytoin in early chick embryos.

Facial nerve schwannomas: a report of four cases and a review of the literature.

OBJECTIVE: To evaluate both the surgical approaches and results of the facial nerve schwannoma cases as diagnosed in our clinic in line with the literature. MATERIAL AND METHODS: The files of 4 cases diagnosed in our clinic as facial nerve schwannoma between 1996 to 2002 were reviewed retrospectively. All the cases were evaluated with detailed history; ear, nose, and throat examination; computed tomography; and/or magnetic resonance imaging. If required, electromyography and audiometric evaluations were made. Fine-needle aspiration cytology was also performed in appropriate cases. The surgical approach used was determined depending on the tumor location and its extent. Facial nerve reconstruction was accomplished if the integrity of the nerve could not be protected. Cases were followed up for facial nerve function, complications, and recurrence. RESULTS: The tumors occurred in the vertical (n = 2), internal auditory canal (n = 1), and the peripheric segment (n = 1) of the nerve. As symptoms, facial paralysis (n = 2), hearing loss (n = 3), tinnitus (n = 1), otorrhea (n = 2), parotid mass (n = 2), and external auditory canal mass (n = 1) were observed. Radiologic investigations provided important informations. However, fine-needle aspiration cytology did not contribute to a correct preoperative diagnosis. The superficial parotidectomy approach (n = 1), retrosigmoid approach (n = 1), and transmastoid-superficial parotidectomy combined approach (n = 2) were used. The integrity of the nerve could not be protected in 3 of the cases. After the reconstruction surgery, the facial nerve function was evaluated as House-Brackmann grade 3 for all 3 cases at the mean 38.6 months follow-up time. No tumors have recurred during follow-up. CONCLUSION: Facial nerve schwannoma is a rare tumor. Through improved surgical and reconstruction techniques, postoperative morbidity is at acceptable levels. The rate of recurrence is low. It should be kept in mind for differential diagnosis of facial nerve paralysis.
